- Code of Conduct (Please note there is no longer a separate version for elementary students)
- Code of Conduct – Arabic (Arabic Translation)
The Dearborn Public Schools consider maintaining a safe, secure, and orderly learning environment our number one priority. We believe, through securing a safe, secure, and orderly learning environment, we foster the development of responsible active citizens of our city, state, and country.
A necessary step to secure such an orderly learning environment is to outline the standards for behavior by our students and staff. The Code of Conduct for the Dearborn Public Schools ensures this first step. It is through the judicious application of our Code of Conduct that we nurture responsible and caring citizens and citizenship by our students.


Animal Land Load Guidelines for Self-Sufficiency (Sustainability)
How many animals can I put on my land and not have to buy feed? This sounds like a pretty simple thing, but it is fairly complex, and involves a range of variables that have to be taken into account.
The short answer is this:
The long answer is that it depends on many factors, which include the breeds of the animals (primarily whether they are large or small breeds), the condition of the land, the amount of attention you want to give the land, and how you stack the animals (which animals are penned together).
Let's start with a more complicated version of that chart above, which includes a few more animals, and which includes some additional information.
Acres Animal Category Quantity
1 Chicken A 200
1 Duck A 100
1 Goose B 60
1 Turkey A 20
1 Lg. Hog ABC 2
1 Goat B 4
1 Sheep B 4
10 Cow C 2
10 Horse C 2
So, what all this means, is that with land that has not been improved, but which started out having a good amount of wild forage, these are the numbers of standard sized animals you can raise on the listed acreage, without over-stressing the land.
But... it also means you mix and match when you have more than one kind of animal. Since goats and sheep have the same quantity limit, you can have 4 goats, or 4 sheep, OR two of each in the same acreage. Same with other animals, a percentage of one offsets a percentage of another animal.
The Category lists the kind of stress the animal puts on the land. You can COMBINE animals from more than one category, and you don't have to fully exchange. For example, if you combine an A and a B, you do not have to compensate for half and half, you can do 60-75% of each instead of 50% of each. This is because they overlap SOME on the kinds of forage and land stress, but not completely, so by combining different categories, you can gain more use of the land. Pigs count in all three categories, because they fully occupy any land they are on.
Keep in mind:
 1. If you have poor land, decrease the numbers by half.
 2. If you raise miniature breeds, you can double the number of animals, sometimes more (up to 4 times with Bantam chickens).
 3. You will need to maintain the forage on the land. Sometimes you will need to plant, sometimes you will need to protect an area while a plant type is coming up, and you may need to put screening around trees to keep goats or pigs from eating the bark.
 4. Your house space does not count in your acreage. If you have a home on 1 acre, then you are going to have to subtract the area you are not using specifically for the animals.
 5. Land area may include land used to raise crops for the animals. You may put the animals on half the land and raise crops on the other half. All of it counts.
 6. If you haul in feed, you can increase your animal loads on the land. If you want to buy half the feed, you can double the numbers of animals. If you do, they will stress the land more, their feet will destroy more habitat, and you may find that you have to purchase 60-70% of the feed in order to compensate for the trampling of forage. It depends on what crops you have on their forage land, and how densely stocked the land actually is.
 7. Planting aggressive growers (things like comfrey, wild blackberry, etc) which tend to take over when not grazed, can increase your forage potentials - but if you stop grazing animals there, they may be difficult to control without heavy grazing. Forage animals are a great way to control aggressive trees which propagate by seed or sucker, such as alders, willows, plum trees, apple trees, etc. The presence of aggressive growers which are also good forage can slightly increase your land loads.
 8. If you are in an area that gets a lot of rain, where plants grow really fast, you may also be able to increase stocking densities.
 9. Watch the land - if it is trampled and you start to lose forage, then you need to back off. If it ends up overgrown in the corners, then you can add animals.
And that last thing really is the determining factor. The guidelines listed are a place to start. If your forage grows faster than it can be consumed, you may add animals. If your land starts showing stress and getting down to dirt and mud, then back off a bit, rotate pastures, etc.
Calculations are based on published information regarding several animal species, with estimates extrapolated for those animals for which we could not locate recommended stocking densities.


Most radiomic features depend on the data acquisition settings, including the scanner brand, the imaging and image reconstruction, and voxel size settings. It is therefore recommended to study radiomic features from images that have been acquired using the exact same scanner and protocol settings. If this is not possible, and if you want to combine radiomic features obtained using different settings in a single analysis, some feature harmonization should be performed.
For PET and CT data, we suggest to harmonize radiomic features using the ComBat approach, that we previously validated (,, and that is freely available as a R routine :
We provide below an example of R script and two sample files (before and after ComBat) involving 3 features, 30 regions of interest for scanner 1 and 30 regions of interest for scanner 2. The code corresponds to using ComBat without any covariate. Before ComBat, the statistical distributions of the 3 features are quite different between scanner 1 (pink) and scanner 2 (cyan) (top row), while after ComBat, the distributions from the two scanners better match for the 3 features.

 Servo System Controlling in CNC Bending Machine
 CNC Bending Machine is a machine to process metal plates and it mainly uses hydraulic system to blend panels into different shapes. Hydraulic system of traditional CNC bending machines generally adopts common three-phase asynchronous motor, thus it has big energy consumption, high temperature and low efficiency, and its parts are vulnerable. With energy saving and emission reduction is concerned by more and more people, new CNC bending machine which uses electric-hydraulic servo system to drive oil pump has emerged. Combination of servo drives and servo motors and adjustment of electro-hydraulic servo of CNC bending machine hydraulic system can reduce system energy consumption and temperature-rising of hydraulic oil and improve operational reliability of equipment at the same time.
 CNC bending machine
 Introduction of techniques
 A work cycle of CNC bending machines can be divided into several states like fast drop, slow drop, pressure maintaining, unload and kickback. When the equipment is working, the system will control oil pump to work, coordinating with work of hydraulic oil circuit control units, and then control the flow of hydraulic system, to reach the reasonable pressure value under different working states. The specific work procedures are as follows:
 1. When sliding blocks of machines drop fast, pressure oil will enter into upper compartment of oil cylinder through hydraulic valve and oil in lower compartment will return back to hydraulic pump through hydraulic valve. In this way, sliding blocks of machines will decline rapidly due to self-weight, and the open prefill valve will charge upper compartment of oil cylinder.
 2. When sliding blocks of machines operate in a slow speed, pressure oil will enter into upper compartment of oil cylinder through hydraulic valve to continue to push sliding blocks to drop.
 3. when sliding blocks of machines return back, pressure oil will enter into lower compartment of oil cylinder through hydraulic valve, rod of oil cylinder will pull sliding blocks to rise and oil in upper compartment of oil cylinder will flow back to oil tank through open prefill valve.
 Thus a work cycle has just finished.
 Application of servo system
 Hydraulic system of traditional bending machines adjusts flow of the system through dosing pump and proportional reversing valve. Since actual flow needed by the system changes while discharge of oil pump is constant, a part of flow will definitely overflow and generate energy loss. Moreover, setting pressure of valve controlling hydraulic system is always higher than actual pressure demanded, which will also cause energy loss. Meanwhile, throttle governing modes have overflow in main pressure valve, which will cause noise, a large calorific value of hydraulic oil, rising temperature, reduction of service life of hydraulic oil and increasing maintenance cost.
 In view of defects of hydraulic system of traditional bending machine and characteristics of forming techniques and processes of equipment, it adopts servo drive, servo motor, and gear pump to adjust control system of flow and pressure of hydraulic system. The details are as follows:
 According to position feedback of linear scale, CNC system will obtain values of flow and pressure needed by the system through algorithm characteristics, output 0～±10V analog control signals to servo drives, adjust speed of oil pump in real time and coordinate with work of hydraulic oil circuit control unit to meet demands of different process terminals on pressure and flow. The program adopts the principles of volumetric speed control and changes flow of oil pump and system pressure by adjusting speed of servo motor, thus avoiding energy consumption caused by traditional throttle governing schemes. Especially at the stage of pressure maintaining and unloading, output of oil is less and oil pump can almost stop operate, which will greatly reduce energy consumption. Meanwhile, response time of servo driven system is shorter and speed of fast drop and return when equipment is working is faster and has a higher efficiency.
 In conclusion, the program can effectively reduce system consumption, has less operation noise and a faster system response, and improves efficiency, and its operation is stable and reliable, its protection function is strong and its operation is simple and convenient. Thus it can not only meet requirements of forming techniques of bending machines and improve product quality and output, but also reduce maintenance costs of equipment, creating favorable economic benefits to users.

Proper subway etiquette is lacking in New York, and the MTA (Metro Transit Authority) has responded with Courtesy Counts, an ad campaign prescribing social norms for good behavior on the subway. As revealed in last week's post, similar ad campaigns have been tried across the globe for decades, yet the problems persist: people still crowd the doors, lean on the poles and spread their legs across several seats. So why do these social norming campaigns seem so ineffective?
In order for these campaigns to change behavior, people must (1) be aware of the norm and (2) feel urged to follow the norm. When asked why the campaign isn't working, most New Yorkers quickly gravitate toward the first reason: a businessman remarked, "Are people really reading [the posters]? They don't catch the eye;" a worker for the MTA agreed, saying, "If more people saw them, they'd work more."
The idea that more information leads to more action underlies many efforts to fix a behavioral problem. The problem with this theory is that people don't always translate their knowledge of what they should do into action. If they did, we'd all be celery-munching marathon runners with perfect self-control, and I would have found a nice image to break up the text here.
The truth is that knowing about a social norm and actually following that social norm are far from the same thing. The MTA's current strategy for making people care about norms relies heavily on people's intrinsic desire to be courteous. Their slogan, "be someone who makes it a better ride for everyone," is effective as long as people wish to be perceived as courteous. For this reason, the campaign enjoys some success—for example, by teaching self-conscious people (like me) who wish to be courteous that removing a backpack during rush hour can help save space.
On the other hand, the greatest limitation to the success of an etiquette campaign is that people must be attentive: attentive to the message and attentive to their behavior. Therefore, even if commuters successfully internalize the messages of the campaign, they may not change their behavior, because they are not mindful of their actions. In fact, we all suffer from limited attention – so although I may have the best intentions to remain courteous, I may not give up my seat to a pregnant or elderly person simply because I fail to notice her presence.
Therefore, although we may be able to improve a social norming campaign in myriad ways – better poster design, catchier messaging, greater visibility of ads, increased social accountability, etc. – these adjustments may not be enough to overcome people's inattention. So perhaps the MTA should instead focus their efforts on creating nudges that encourage good behavior without requiring people to make the active decision to be courteous.
As discussed last week, most of our decisions and actions are influenced by our context. Train station designers across the globe have used this insight to design a simple intervention to improve flow in and out of the train:
A few weeks ago, the MTA followed suit, installing the following signage in two stops in Manhattan:
The MTA will be testing the effectiveness of this nudge in the coming weeks before deciding whether to scale it to all stations. At a glance, however, this nudge seems more likely to succeed than the original Courtesy Counts poster. It's both more visible and timelier than an etiquette poster: you are likely to look down at the platform to determine where the doors will open, and when you do, you'll be reminded to step aside as you wait for the train to come. In fact, you would have to actively choose to ignore the message to step in front of the opening train doors.
There are similar small changes that could be made to a train car to address other problems around etiquette. For example, let's take the problem of crowding the doors inside the subway car:
In general, I hypothesize that people entering a subway car without available seats will default to standing where it is most spacious and comfortable. I say "default" because in many instances I do not make an active choice about where I want to stand – I simply enter a train and will not move further into the car unless there is a reason to keep going.
In this case, people can be nudged to move into the center of the train car in several different ways. The easiest would be to simply point the way:
This nudge is reminiscent of the platform nudge described above: the hope is that a gentle visual cue may be enough of a reminder to encourage passengers to continue moving into the car.
Beyond just pointing the way, you could also change the context of a subway to make standing around the doors less comfortable. An extreme solution might be to shine a bright light around the doors, every time they open. In this case, passengers may feel uncomfortably illuminated when blocking the doors and choose to step out of the spotlight and into the interior of the car.
A more palatable solution would be to rearrange the poles in the subway car. Currently, the newest generation of New York subway cars is designed with poles clustered in front of the doors:
A solution to bring people further into the cars is to simply move the center poles further inside:
By providing more handholds further away from the doors, people will be more likely to take the extra step or two inside and leave room for others to enter.
Whatever the details of the intervention, we should take a hint from 70 years of failed etiquette campaigns and think beyond a poster for creating real change. As one woman I interviewed said, "Most New Yorkers just don't give a ****." If that's the case, it's time we stop relying on people's attention to courtesy and instead design a subway system that nudges positive behavior—especially if the solution could be as easy as painting some arrows on the floor or moving a subway pole a few feet further inside the car.

Co-Training for Domain Adaptation[PDF] [BibTeX]
Domain adaptation algorithms seek to generalize a model trained in a source domain to a new target domain. In many practical cases, the source and target distributions can differ substantially, and in some cases crucial target features may not have support in the source domain. In this paper we introduce an algorithm that bridges the gap between source and target domains by slowly adding both the target features and instances in which the current algorithm is the most confident. Our algorithm is a variant of co-training, and we name it CODA (Co-training for domain adaptation). Unlike the original co-training work, we do not assume a particular feature split. Instead, for each iteration of co-training, we add target features and formulate a single optimization problem which simultaneously learns a target predictor, a split of the feature space into views, and a shared subset of source and target features to include in the predictor. CODA significantly out-performs the state-of-the-art on the 12-domain benchmark data set of Blitzer et al.. Indeed, over a wide range (65 of 84 comparisons) of target supervision, ranging from no labeled target data to a relatively large number of target labels, CODA achieves the best performance.

Audience segment composition
This feature might not be enabled in your DFP environment.
Each member of an audience segment represents an audience identifier associated with a user's device. As your audience segment collects members, you can see a breakdown of what audience identifiers compose the segment by clicking Inventory Audience segments in DFP.
In the table that lists all audience segments, the columns below display information about the audience segment member composition:
- Total size: The number of members currently in a segment.
- Mobile web size: The number of mobile web users that comprise a segment.
- AdID size: The number of Android app users (identified with an AdID) that comprise a segment.
- IDFA size: The number of iOS app users (identified with an IDFA) that comprise a segment.
- PPID size: The number of users, identified by a publisher provided identifier (PPID), that comprise a segment.
- These totals are updated periodically throughout each day.
- The Mobile web, AdID and IDFA size values are rounded to two significant digits (for example, "22,000" instead of "22,382") and if there are fewer than 50 members in any category, DFP displays 0.
- The total size of an audience segment, updated approximately every 30 minutes, must be at least 100 before it is eligible for ad serving. We use statistical modeling and sampling to estimate the segment total size, so the size shown might not exactly match a number of identifiers uploaded. Small audience segments are subject to a higher variance in model estimates, so using lists with at least 150 members is recommended.
- The sum of "Mobile web size", "IDFA size", and "AdID size" values may not equal the "Total size" value for a segment because of users on other targeted devices or environments.
- For third-party audience segments, the "Total size" value shows how many identifiers are provided in the segment, but doesn't necessarily reflect the total amount of unique impressions you'll get from the segment. This could be because some identifiers are stale or based in another country.

'Soil moisture' is a measure of the amount of water contained within the soil.
It was not possible to create probabilistic projections of changes in soil moisture for UKCP09. Different modelling groups use different definitions of this variable, so it was not possible to construct Pdfs combining results from variants of Met Office models with those from other climate models. Without this key aspect of our methodology, it was not possible to provide probabilistic projections.
In the absence of probabilistic projections for soil moisture in UKCP09, three possible alternative sources of projections of transient changes during the 21st century are available:
- The 17-member ensemble of variants of the Met Office GCM
- The 11-member ensemble of variants of the Met Office RCM
- The ensemble of other global climate models, available as part of the CMIP3 project
Data from the first two (Met Office GCM and RCM) is available from the Climate Impacts LINK project, operated by BADC. It is recommended that those needing soil moisture information use changes from the 11-member Met Office RCM ensemble in the first instance.
- Variables for which probabilistic projections could not be provided in are outlined in section 5.10 of the UKCP09 Briefing Report. More details are provided in section 4.8 of the UKCP09 Climate Change Projections report.
- The 11-member RCM data is described in the Reports & guidance section and in section 5 of the UKCP09 Climate Change Projections report.
- More details about the climate models used in UKCP09 are given in Box 2.1 of the UKCP09 Climate Change Projections report. A commentary about the strengths and weaknesses of climate models is given in Annex 3.
- For an overview of how probabilistic projections are created and presented, go to Box 3 of the UKCP09 Briefing report. More details are provided in Chapter 3 of the UKCP09 Climate Change Projections report, including an overview of the methodology.
- Recent trends in wind speed are presented in the Observed Trends report.
- The 11-member RCM dataset is available on the BADC's LINK website.
- The CMIP3 multi-model dataset can be freely accessed for non-commercial purposes via the CMIP3 website.


text: Minimally invasive surgery for total mesorectal excision (TME) remains technically challenging due to poor maneuverability within the pelvis, which makes extremely difficult to introduce a laparoscopic stapler (LS) for the rectal transection. We aim to perform a systematic review and meta-analysis on robotic TME after the use of robotic stapler (RS) or LS after robotic TME. A systematic literature search was performed using PubMed, MEDLINE, and Cochrane Database. Participants who underwent robotic anterior resection were considered following these criteria: (1) studies comparing RS and LS; (2) studies reporting the rate of anastomotic leakage (AL). The primary outcome was the risk of AL. Secondary outcomes included the number of firings of stapler needed. A meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement was performed. A total of 4 studies including 391 patients (LS = 251, RS = 140) were included for analysis. Regarding the number of firings, overall results suggest that the rectal stapling was achieved with less firings in the RS group, but the difference is not significant [risk difference, (95% CI) 0.42 (− 0.13, 0.97)]. There was a 56% increased odds of AL for LS compared with RS; however, this was not statistically significant (OR: 1.56; 95% CI 0.59, 4.14). With the current literature evidence, the present study could not demonstrate a clear benefit of the RS over the LS. Although the development of an AL is multifactorial and unpredictable, our data may suggest that the use of the RS could help reducing the risk of AL. There is a need of future randomized clinical trial to assess the possible benefits of the RS.


Optimizing Material Handling for Better Throughput
Material Handling Optimization
Wire baskets, trays, and carriers are used for a variety of applications from work holding to heat treating to cleaning operations. Wire baskets are used in many applications because they are strong, yet lightweight. The open construction of wire baskets allows air circulation, greater visibility of the product, greater accessibility of the product and allows better run off of cleaning solutions during washing or degreasing operations.
The rounded, smooth surface of the wire can allow parts to be guided into chambers or cells without fracturing or nicking fragile components, whether it is a machined metal component for medical, automotive or military applications or a film protecting food products or pharmaceutical preparations. Wire containers are strong and can easily withstand the wear and tear of factory use. Tooling and fabrication costs for wire baskets can be more economical than baskets made of other materials. Metal baskets are better for the environment because when the baskets are no longer needed (due to a change in product or process) the metal can be recycled to be made into reprocessed metal to keep obsolete material out of landfills.
Material handling can become an issue that does not usually arise unless components are being handled improperly. The improper handling often causes parts to become damaged and may contribute to more scrap and lower productivity (due to rework or increased inspection) in certain assembly areas. If parts are not processed efficiently or moved to the next station quickly enough, throughput can be impacted and cause downtime in downstream operations.
Proper material handling techniques can decrease the indirect cost of manufacturing by reducing the number of times a part must be handled and decrease the loss or damage due to mishandling. Many handling baskets also double as storage bins. If parts are not stored properly, damage may occur. Baskets can be designed with a stacking feature which reduces the amount of floor space required for goods in process.
Material Processing
A related issue in material handling is material processing. Material processing can be heat treating, degreasing, washing or sterilizing. The need for adequate material processing containers becomes apparent when parts cannot be processed quickly enough due to improper design, or insufficient capacity. Many components have to be oriented in a certain way to ensure consistent cleaning and drainage or plating coverage or heat treating uniformity. Acme Wire Products can work with your processing engineers to help develop a processing rack or basket that meets your needs.
The more sophisticated or complex the component, the more engineered the container becomes. A component which must go through several machining or fabricating operations already has a significant labor cost already applied to it before it reaches its final state. In this instance, the manufacturer does not want the operators to carelessly put parts into a box and send them onto the next station. A custom basket or rack for handling these items can prevent damage due to mishandling.
For cleaning and sterilizing operations, 300 series stainless steel, either 304 or 316/316L is typically used as the baskets are going into a wet, high-temperature environment. For most handling baskets, zinc plated steel is the preferred material. For new basket applications, Acme Wire Products' engineers will consult with the customer and consider the weight of the product the basket will hold, how many parts need to be processed per batch, the part orientation and numerous other factors.
A pin-style basket is typically used to hold parts with a small internal diameter. Larger parts that can be located on the outer surface will often be held in a grid style orientation. Sometimes parts are oriented between rails or on rings. Proper part placement and dimensional accuracy become critical when parts are being loaded or unloaded in automated cells.
Acme Wire Products Co., Inc. of Mystic, CT specializes in designing and fabricating custom wire and metal material handling and processing baskets. As a full-service metal fabricator, Acme can utilize materials in addition to and in conjunction with wire, depending upon a customers' requirement. Sheet metal, perforated stock, stampings or tubing are all materials that can be combined with wire to obtain the maximum effectiveness in solving our customer's handling needs.
Acme Wire Products has designed, recommended and manufactured custom handling and processing baskets for customers in many diverse markets. We offer the benefit of our almost 50 years' experience in the manufacture of carriers for hardware, medical, firearms, pharmaceutical, automotive, optical and food processing industries. Wire carriers can hold parts as delicate as a glass lens or vial or an egg or an electronic component or as sturdy as a gear or a casting.
Often, when a customer is installing a new sterilizing or degreasing line, they will request custom wire baskets to fit their new equipment. Acme Wire's designers will work with the customer to establish a carrier that will afford the greatest effectiveness and coordinate manufacturing with the installation of their new equipment. Acme Wire also builds baskets, racks, and carriers as components to commercial washing and sterilization equipment.
The design of wire baskets and most wire fabrication is limited only by one's imagination (and the limitations of technology). There are almost as many types of baskets as there are different parts to be contained. Contact Acme Wire Products to assist you in determining the design which is best suited your handling and processing requirements as well as fabricating the carriers to your specifications!

Dear Parents, Guardians, Students, and Staff,
On October 5, 2021 the Alberta Government announced that it would reinstate contact tracing and notification in schools for confirmed cases of COVID-19. Beginning this week, Alberta Health Services (AHS) began notifying our School Division of confirmed cases of COVID-19.
The school will notify those impacted directly as a close contact of an AHS-confirmed case who attended school while infectious. Students and staff without symptoms are not required to isolate or quarantine due to potential exposure.
The following directives from AHS and CMOH Order 48-2021 only apply for Kindergarten to Grade 6 classes: during any 5-day period where 3 or more members of a class cohort are confirmed COVID-19 cases, unvaccinated members of the class cohort will be moved to at-home learning for a 10-day period. There is no similar requirement for Grades 7-12 at this time.
In order to help families and staff have easy access to active case numbers, we have developed a COVID-19 Dashboard. This webpage provides a summary of AHS-confirmed active cases which impact our schools and is updated at the end of each workday. According to AHS guidelines, active cases expire 10 calendar days from when the individual was last present at school.
You may wish to visit the Alberta COVID-19 School Status webpage for more information about school status classification and the provincial school outbreak alert list.

Axiom of choice
In mathematics the axiom of choice, sometimes called AC, is an axiom used in set theory. The axiom of choice says that if you have a set of objects and you separate the set into smaller sets, each containing at least one object, it is possible to take one object out of each of these smaller sets and make a new set. You do not always need to use the axiom of choice to do this. You do not need to use the axiom of choice if the starting set is finite, or if the starting set is infinite and has a rule for how it can be divided built in. For example, for any (infinite or finite) sets of pairs of shoes, one can pick out the left shoe from each pair, but for an infinite collection of pairs of socks, the axiom of choice is needed.

Lignin-fueled photoelectrochemical platform for light-driven redox biotransformation†
The valorization of lignin has significant potential in producing commodity chemicals and fuels from renewable resources. However, the catalytic degradation of lignin is kinetically challenging and often requires noble metal catalysts to be used under harsh and toxic conditions. Here, we report the bias-free, solar reformation of lignin coupled with redox biotransformation in a tandem structure of a BiVO4 photoanode and perovskite photovoltaic. The tandem structure compensates for the potential gap between lignin oxidation and biocatalytic reduction through artificial Z-schematic absorption. We found that the BiVO4-catalyzed photoelectrochemical oxidation of lignin facilitated the fragmentation of higher molecular weight lignin into smaller carboxylated aliphatic and aromatic acids. Lignin oxidation induced photocurrent generation at the photoanode, which enabled efficient electroenzymatic reactions at the cathode. This study successfully demonstrates the oxidative valorization of lignin as well as biocatalytic reductions (e.g., CO2-to-formate and α-ketoglutarate-to-L-glutamate) in an unbiased biocatalytic PEC platform, which provides a new strategic approach for photo-biocatalysis using naturally abundant renewable resources.

A system of Kohn-Sham equations was solved self-consistently for the two-dimensional, spatially separated electrons and holes. A series of magic numbers were found for the total angular momentum of the electrons and holes in a strong magnetic field. The change of the angular momentum of the charge carriers was shown to lead to oscillations of the persistent current.
Keywords: electron-hole quantum dots, the Kohn-Sham equations, persistent current.

Hopscotch, choreographed by Hélène Cathala, explores the predicament of five individuals caught in a game where the rules are constantly changing. Confronting the reality of being part of a group, they ask: How do we deal with rules? How can we trick each other? How can we survive? Do we struggle or surrender? Although childish and sometimes unreasonable, the rules of the game reveal a framework which could be a metaphor for our lives: Games can turn to cruelty and a playground can become a battlefield, but with the but with the start of each new game, joy and energy re-appear.

This is yet another Ping Monitor utility written in VB.NET on.NET Framework 2.0. It fulfills the need of steadily monitoring through a "PING" the status (the aliveness) of some PCs and servers on a network, keeping a history of each state transition (ON to OFF and viceversa) and visually highlighting the last status of each machine.
This application is far from being a complete and sophisticated tool. I wrote it for a colleague who needed a starting point for a more advanced and customized tool implementation.
One service, one database, one IU
In order to continuously monitor some machine, we need to have a monitoring EXE continuously runnning. So, I decided to implement the "monitor engine" as a Windows Service application (taking advantage of unattended execution, automatic restart in case of power failure, and so on). This
PingMonitorService simply has to:
- read from some configuration storage (such as a database table) the list of machines to be monitored (along with the monitoring frequency);
- execute the actual monitoring sending a "PING" to each machine configured as to be monitored;
- log the outcome of each "PING" somewhere.
Other than a Windows Service for the monitoring and a database as a storage, we obviously need also a user interface (UI) to interact with the configuration and the log; that's why I created a simple Windows Form application (named
PingMonitor) to accomplish these tasks: showing the last PING status of the monitored machines and editing the
I decided to use a SQL Server 2000 (or 2005) database to host both the configuration (that is, a list of machines to be monitored) and the log.
The following are the two table schemas, expressed in T-SQL code, with some explanations.
The configuration table
CREATE TABLE HostList (
ID int IDENTITY(1,1) NOT NULL,
Host nvarchar(50) NULL,
IsHost char(1) NULL,
ShowInMonitor char(1) NULL,
DoPing char(1) NULL,
PingFreq int NULL,
IDparent int NULL,
CONSTRAINT PK_HostList PRIMARY KEY CLUSTERED (ID ASC)
WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON PRIMARY
) ON PRIMARY
HostList table will contain the list of the machines to be monitored. For each machine, it stores: the machine name with a unique ID (
ID fields), the frenquency of monitoring (
PingFreq field, expressed in seconds), a flag indicating if the monitoring is currently activated (
DoPing field) and a flag indicating if the specific machine has to be shown in the UI (
Being able to list a hierarchycal tree enables you to organize the machines to be monitored in groups and subgroups, the
HostList table supports the concept of parent-child node relationships (via the
IDparent field) and the concept of "folder" tree nodes, that are intermediate nodes not corresponding to an host but simply being the parent of other nodes (for them, the
IsHost flag is not set to "yes").
The user interface provided by the
PingMonitor application allows you to visually edit the tree while directly modifying the underlying
HostList table (please, notice that the deletion of nodes and the addition of children nodes is allowed through the context menu on the tree).
The log table
CREATE TABLE PingLog (
Host varchar(50) NOT NULL,
Status varchar(5) NOT NULL,
RecordingDate datetime NOT NULL,
CONSTRAINT [PK_PingLog] PRIMARY KEY CLUSTERED (Host ASC, Status ASC,
WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON PRIMARY
) ON PRIMARY
PingLog table will contain an entry for each detected state transition (ON to OFF or viceversa) for each monitored machine during a monitored period of time. The
Host field contains the name of the monitored machine, the
RecordingDate field contains a timestamp of the recorded entry and the
Status field simply contains the value "ON" or "OFF" (respectively indicating a successful and an unsuccessful "PING").
Some notes about the service
PingMonitorService has been implemented on the standard Windows Service application template of Visual Studio 2005. Being a standard.NET Windows Service, it has to be installed through the installutil.exe utility (see here for reference).
When started, the service reads its CONFIG file in order to retrieve:
- the connection string to the configuration database (see
- the configuration reloading frequency (see
ReloadConfigFrequency appSetting): it indicates the number of seconds before reloading all the configuration parameters (this enables the service to adapt its behavior based on new settings in the
HostList table eventually modified by the user through the PingMonitor UI).
To determine if it's time to "PING" a machine, the service simply looks at the total number of seconds passed after midnight and checks if this number is a multiple of the specific
PingFreq for that host (notice that only status transitions are stored, not each status detection).
If CurrentSecond Mod CInt(dr("PingFreq")) = 0 Then
Dim IsAlive As Boolean = HostIsAlive(dr("Host"))
Dim LastStatus As String = HostLastStatus(dr("Host"))
If LastStatus = "" OrElse _
(LastStatus = "ON" And Not IsAlive) OrElse _
(LastStatus = "OFF" And IsAlive) Then
Notice that the polling interval in the
MainTask() is currently set to 900ms, to be sure that at least one "tick" happens for every second (obviously, it could occur twice in some seconds). If the host list is very very big, the execution of the
TryPing() method could be long enough to make the service miss some "PING" to some hosts (so please carefully configure the hosts list and the specific
The "PING" itself is done, in a very simple way, through the
Private Function HostIsAlive(ByVal Host As String) As Boolean
Dim pingSender As New Ping
Dim reply As PingReply
reply = pingSender.Send(Host)
If reply.Status = IPStatus.Success Then
Catch ex As Exception
Some notes about the UI
The UI application is very simple; it consists of two forms: the monitoring form and the configuration form.
The application needs a CONFIG file where the connection string to the support database is specified (see
The monitoring form is just a
DataGridView populated by a query on the
PingLog table; the query is designed to show only the last entry for each host having
The refresh frequency for the
DataGridView can be specified in the
ReloadFrequency appSetting of the application configuration file. Entries with an "OFF" status are highlighted by simply implementing the
CellFormatting() event handler:
Private Sub dgMonitor_CellFormatting(...)
Dim v As Object = dgMonitor.Rows(e.RowIndex).Cells("Status").Value
If v IsNot Nothing AndAlso v.ToString() = "OFF" Then
For Each i As DataGridViewCell In dgMonitor.Rows(e.RowIndex).Cells
i.Style.BackColor = Color.Orange
The configuration form contains a treeview with a detail panel, shown when a host node is selected (see the first picture in the article).
No special remarks needed on this. Just notice that the update of the underlying
HostList table is done immediately after modifying values on the UI controls, through updates on the corresponding
DataTable suddenly written down by the
As stated in the Introduction, this application is to be considered as a starting point for a more advanced and customized tool implementation. Its basic idea and implementation are intentionally very simple, hoping it can be useful for you in building something more complex.

|"All Creatures Great and Small"
|James Herriot inspired many to become vets in
Millions of Indians still live directly off animal husbandry. Innovative application of
modern veterinary science can help improve the lives of both the animals and their owners.
Want to become Indias Herriot?
Most people will have had some contact with vets
either through the family pets, or on TV in the form of James Herriot, the pen name of
James Alfred Wight a British veterinary surgeon and writer.
The work they do helping sick creatures will tug at the heartstrings. While
these guys make it look easy, becoming a vet is seriously hard work. In fact, getting into
a veterinary career is harder than becoming a doctor! Until recently, vets have had to
struggle against indifference to their profession in the developing world. But these days,
the welfare of domestic animals is seen more positively as an essential part of rural
development and an indication of a modern progressiveoutlook.
The large majority of vets will end up working in private practice small
operations, of between one and four animal doctors where family pets will be the
mainstay of these businesses. Most veterinary doctors, develop a particular area of
expertise. As there are limited opportunities in areas of specialised research and
breeding of animals in India, a majority of veterinarians choose to work in urban areas,
where the work would mostly include the care and handling of domestic pets, or in the
government's animal husbandry departments. As with a doctor handling the medical ailments
of human beings, a veterinarian's work involves diagnosing the ailment of an animal,
through physical and clinical examination, and the administration of appropriate
medication. It also involves the timely administration of vaccines for preventing disease,
and advising on matters of nutrition

What happens when the user selects "Safely Remove Drive" when the drive is a USB Flash Memory device and what is the risk if the user simply pulls the drive without selecting that operation?
I am on Precise (12.04) and the drive is a USB 3.0 flash memory.

When the user selects "Safely Remove Drive", the partition of the media (in this case the USB flash memory) is "unmounted" as soon as the drive has finished its current operation(s).
Then, it's safe to proceed and physically remove the USB stick, because the drive is "switched off".
If you do not "eject" the media, meaning that is still mounted (i.e. linked to a directory, usually in /media), and you remove the drive, you can corrupt the files on the USB stick, even if you think the system is not reading/writing anything on the drive itself. So my advice is to always eject it.
This is just a quick answer, you can also check this article:

Saving a Path
Save Path commandAs we have already mentioned, the "Work Path" means "temporary" path. For example, when you create a new path from a selection or from text, it replaces the previous Work Path*.
*Paths created from shape layers and vector masks are saved automatically.
To secure the created Work Path:
 1. Open the "Paths" dialog.
 2. Make sure that the "Work Path" is selected in the Paths list.
 3. Apply the "Save Path" Save Path command command.
 4. In the dialog box that appears, enter desired path name and click "OK".
Please note that you can't overwrite existing paths. For example, the program won't save a path as "Path 1", in case a path with that name already exists.
In conclusion, let's touch saving the files containing paths. Unlike vector shapes, paths may be saved to various file types. For example, you can incorporate your vector drawings into a JPEG file and publish it on the Web.

From Ohio History Central
Marietta from Harmar Hill, by Charles Sullivan
Charles Sullivan was an important Ohio artist during the nineteenth century.
Born in Frankfort, Pennsylvania in 1794, Sullivan spent his youth in Pennsylvania. He began to study art in the 1810s. His most important teacher was Thomas Sully, an artist based in Philadelphia, Pennsylvania. Sullivan later opened his own studio in Philadelphia. In 1827, he moved to what is now Wheeling, West Virginia and in 1833, to Marietta, Ohio.
In Wheeling and Marietta, Sullivan became especially well known for his landscapes. His river scenes focused mainly on the Ohio River. He also made a number of paintings of Indian earthworks, especially in the vicinity of Marietta. Sullivan's paintings of the Marietta Earthworks provide valuable information since many of the earthworks are no longer in existence.
Sullivan resided in Marietta for the remainder of his life. He died in 1867.
The Ohio Historical Society's Campus Martius Museum in Marietta, Ohio contains examples of Charles Sullivan's work.

Key Difference – Exome vs Transcriptome
A gene contains coding and non-coding regions within it. Coding sequences are known as exons, and non-coding sequences are known as introns. The nucleotide sequence of the exons of a gene represents the genetic code of the gene to synthesize the specific protein. Hence, exons remain in the mRNA molecule. The total exon region of the genome is known as exome, and it is an important part of the genome. The genetic code of the genes is converted into the genetic code of the mRNA molecule, which is needed for the production of protein. The entire mRNA molecules transcribed in a cell or a cell population at a time is known as a transcriptome. The key difference between exome and transcriptome is that exome represents the sequences of the exon regions of the genome while transcriptome represents the total mRNA of a cell or a tissue at a given time.
What is Exome?
Genes are composed of exons, introns and regulatory sequences. Exons are the gene regions which are transcribed into mRNA sequence during the transcription. Introns and other non-coding regions are removed during the transcription. The nucleotide sequence of exons determines the genetic code of the gene which synthesizes the specific protein it codes. Only exons remain within mRNA of a protein. The collection of exons in the genome is known as exome of an organism. It represents a part of the genome which is expressed in genes. In humans, exome accounts 1% from the genome. It is the protein-coding portion of the human genome.
What is Transcriptome?
The transcriptome is the collection of all protein-coding and non-coding transcripts (RNAs) in a given tissue. Transcriptome represents the collection of total mRNA molecules expressed by the genes in a cell or a tissue. The transcriptome of a cell can be varied with the transcriptome of another cell type. The transcriptome is also dynamic – it changes with time in response to both internal and external stimuli. Even within the same tissue or within the same cell type, transcriptome can change after few minutes.
Transcriptome differs from exome of an organism. Transcriptome includes only the expressed exome sequences. Though the exome of a cell remains the same, transcriptome differs among cells since gene expression is not same for all cells or tissues. Only essential genes are expressed in different cells and tissues. Gene expression is a tissue or cell type specific process. It is regulated by various factors including environmental factors. Therefore, transcriptome can vary with external environmental conditions.
Transcriptome is used as a precursor for proteomics studies. All proteins are derived from mRNA sequences. Translational modifications can result in the changes in proteins. However, transcriptome provides important basic information for the proteomic studies.
What is the difference between Exome and Transcriptome?
Exome vs Transcriptome
|Exome is the collection of protein-coding region of the genes.||Transcriptome is the collection of all transcribed RNA including mRNA.|
|Exome is studied using DNA sample.||Transcriptome is studied using an RNA sample.|
|Whole exome sequencing is the method of studying exome.||RNA sequencing is the method of studying transcriptome.|
Summary – Exome vs Transcriptome
Exons are the coding sequences of the genes and determine the mRNA sequences of the proteins. The collection of these coding sequences (exons) is known as exome of an organism. Genes are transcribed into mRNA molecules prior to making proteins. The total mRNA molecules of a cell or a tissue at any given time are known as transcriptome. Transcriptome represents the genes that are being actively expressed into mRNA at any given time. Transcriptome is cell and tissue specific and affects with the environmental conditions. This is the difference between exome and transcriptome.

Augustus Edward Hough LoveArticle Free Pass
Augustus Edward Hough Love, (born April 17, 1863, Weston-super-Mare, Somerset, England—died June 5, 1940, Oxford), British geophysicist and mathematician who discovered a major type of seismic wave that was subsequently named for him.
Love held the Sedleian professorship of natural philosophy at the University of Oxford from 1899 to 1940. In his analysis of earthquake waves, Love made the assumption that the Earth consists of concentric layers that differ in density and postulated the occurrence of a seismic wave confined to the surface layer, or crust, of the Earth. This wave would be propagated as a result of the difference in density between the crust and underlying mantle. His prediction was confirmed by recordings of the behaviour of waves in the surface layer of the Earth. He proposed a method—based on measurements of Love waves—to measure the thickness of the Earth's crust. In addition to his work on geophysical theory, Love studied elasticity and wrote A Treatise on the Mathematical Theory of Elasticity, 2 vol. (1892–93).

Measuring angular momentum in atomic systems
 1. Perhaps rather an elementary question, but I can't find a clear answer in my textbooks:
 Would I be right in thinking that we never actually measure directly the angular momentum of atomic systems, but rather: using the results of QM calculations about structure, and knowledge of the selection rules, we *infer* it from spectral transitions?
 2. jcsd

 What would you consider to be a "direct measurement" of angular momentum?
 The Einstein - de Haas effect demonstrates that the microscopic angular momentum of electrons in a metal contributes to the object's total macroscopic angular momentum. Briefly (and probably oversimplified), you start with an object that's not rotating, then flip the spins of the electrons, and observe that the object starts to rotate macroscopically in order to maintain the same total angular momentum.
 4. You've identified the origin of my question, as I could not think of how an experiment could observe angular momentum in atomic systems directly.
 Clearly, the Einstein-de Haas effect does demonstrate a way to do this - and spin angular momentum at that (which is what I'm pursuing).
 However, I'm still left wondering how angular momentum is identified from atomic spectroscopy. I doubt that early work on atomic spectra relied on the Einstein-de Haas effect.
 Can you, or anyone else, tell me how it's conventionally done?

 Er.. the angular momentum of an atom is the origin of magnetism in solids! One doesn't need any "spectroscopy" studies to get that.
 6. OK - let me put it a bit more precisely:
 I'm asking about the orbital and spin angular momenta of electrons in, for example, low density gaseous states.
 Textbooks glibly mention electrons being in states |n,l,m,s>
 But how, observationally, do we come to know what m(l) and m(s) are for the states between which we observe spectral lines?
 Suppose I excite some sodium vapour, and as Wikipedia states:
 "One notable atomic spectral line of sodium vapor is the so-called D-line, which may be observed directly as the sodium flame-test line (see Applications) and also the major light output of low-pressure sodium lamps (these produce an unnatural yellow, rather than the peach-colored glow of high pressure lamps). The D-line is one of the classified Fraunhofer lines observed in the visible spectrum of the sun's electromagnetic radiation. Sodium vapor in the upper layers of the sun creates a dark line in the emitted spectrum of electromagnetic radiation by absorbing visible light in a band of wavelengths around 589.5 nm. This wavelength corresponds to transitions in atomic sodium in which the valence-electron transitions from a 3p to 3s electronic state. Closer examination of the visible spectrum of atomic sodium reveals that the D-line actually consists of two lines called the D1 and D2 lines at 589.6 nm and 589.0 nm, respectively. This fine structure results from a spin-orbit interaction of the valence electron in the 3p electronic state. The spin-orbit interaction couples the spin angular momentum and orbital angular momentum of a 3p electron to form two states that are respectively notated as 3p(2p0,1/2) and 3p(2p0,3/2) in the LS coupling scheme. The 3s state of the electron gives rise to a single state which is notated as 3s(2S1 / 2) in the LS coupling scheme. The D1-line results from an electronic transition between 3s(2S1 / 2) lower state and 3p(2p0,1/2) upper state. The D2-line results from an electronic transition between 3s(2S1 / 2) lower state and 3p(2p0,3/2) upper state. Even closer examination of the visible spectrum of atomic sodium would reveal that the D-line actually consists of a lot more than two lines. These lines are associated with hyperfine structure of the 3p upper states and 3s lower states. Many different transitions involving visible light near 589.5 nm may occur between the different upper and lower hyperfine levels.[8][9]"
 (see original in Wiki to see the term symbols displayed correctly).
 Now, how precisely do we come to be able to state that a transition is between any of the above two states - ie to identify the states' various quantum numbers including the angular momenta?
 As posed in my original question - the only way I can see this being achieved is if one first *calculates* the structure of the spectrum and thus the associated n,l,m,s, values, and then one assigns the observed spectral lines to those theoretically identified states. So one never actually observes the m(l) and m(s) values, but as mentioned in the first post, one infers them.
 Or is there some other way to do this?
 7. jtbell
 Staff: Mentor
 One way (there are probably others) to associate spin and orbital angular momentum quantum numbers of initial and final states with particular spectral lines is via the Zeeman effect. When you apply an external magnetic field, the energy levels of the different spin states shift and/or split by amounts that depend on the angular momentum quantum numbers, and on the strength of the magnetic field.
 8. Yes, what you say is correct, but I think I'm failing to make explicit the point of my question.
 It seems to me that all the answers I've received come from hindsight, as is the case with textbooks.
 But how do we know *from the outset* what the quantum numbers are (which lines correspond to transitions from the lowest values), and what the units of spin and orbital angular momentum are initially, unless we have an atomic model of some sort to start with.
 For example: If you look at Ch1, Vol 1 of P.W. Atkins' "Molecular Quantum Mechanics", he outlines how Balmer, Rydberg and Ritz worked out some regularities in spectral lines which led Bohr to propose a model for hydrogen, based on a number of assumptions, including that:
 "The stationary states are to be determined by the condition that the ratio of the total energy of the electron to its frequency of rotation shall be an integral multiple of h/2. For circular orbits this is equivalent to the restriction of the angular momentum of the electron to integral multiples of h/(2pi)"
 ...and the calculation based on (all) the postulates yields the electron's energies in the hydrogen atom as:
 E(n) = - mu*e^4/(8n^2h^2eta^2) (mu being a reduced mass)
 ...where n = 1,2,3... is the first quantum number. And the result agrees well with experiment (as far as early observations went).
 So, it appears that even at the outset, the unit of angular momentum is fed into the model, and not itself observed. The first quantum number is identified by a model, and I suspect that the *ranges* of possible values of l and m(l) drop out of the spherical harmonics as solutions to the Schrodinger equation - and that these provide the original basis for *interpretation* of the observations, rather than direct measurement of orbital angular momentum. And m(s) emerges from the doublet structure of spectral lines but still refers to the *calculated* unit h/(2pi), again rather than being measured directly.
 I think I'm convincing myself that my original point was true, but it would be good to know if I'm wrong.
 Thanks for the stimulus of your contributions.

 Bohr's atomic model has been superseded for over eighty years by modern quantum mechanics. The quantum numbers for orbital angular momentum arise directly from the solution of the Schrödinger equation.
 For spin, I think you have to go further to the relativistic Dirac equation, and assume that the magnitude of the spin angular momentum has a certain value; but after that, the mathematics of addition of quantum-mechanical angular momentum determine everything else. (Someone with more expertise than I in atomic physics is welcome to correct me on this.)
Have something to add?


What are your thoughts about testing following high risk travel? Should testing be done within 72h of travel or should that employee wait 5 days after his/her travel?
The best response to this question is that "it depends". From the question, I assume an employer or consultant is considering using a test to modify a recommended duration of quarantine after a high-risk exposure, such as travel, in an asymptomatic individual.
With the assumption above, and taking when to test out of the picture, my advice for travel within the US is to first review local requirements or recommendations, as many US states or cities require/recommend quarantine for travelers from certain locations. If local requirements/recommendations alone are not an issue, then some international travel, type of travel, or activities in which the individual participated, might be identified as high risk, warranting quarantine, staying home as much as possible while ensuring wearing a face covering and physical distancing. The CDC lists the following as high risk travel related activities.
 - Being in an area that is experiencing high levels of COVID-19, including destinations with a Level 3 Travel Health Notice. You can check the Travel Health Notices for recommendations for places you have traveled, including foreign countries and U.S. territories. You can also check states, counties, and cities to determine if these areas are experiencing high levels of COVID-19.
 - Going to a large social gathering like a wedding, funeral, or party.
 - Attending a mass gathering like a sporting event, concert, or parade.
 - Being in crowds – for example, in restaurants, bars, airports, bus and train stations, or movie theaters.
 - Traveling on a cruise ship or river boat."1, 2
If the employee in question is considered a critical or essential employee, following the CDC recommendations for serial testing might be an option3 or other recommendations to limit risk of transmission of the virus4
In general, use of a single test (not serial testing) in an asymptomatic individual to evaluate quarantine duration, is only useful if positive. In that situation, you know the individual's status and contact tracing can be initiated. The results of a single test, if negative, cannot appropriately be used to justify shortening the duration of a quarantine period. The positive predictive value and negative predictive value of any single test, false negative and false positives rates depend on the type of testing used, prevalence of COVID-19, and timing of the test in relation to when the exposure occurred and the clinical status of the patient. An OEM provider could help assess some of these factors and interpret the results for a particular patient or help design an appropriate workplace policy.
There may be situations after travel where serial testing is reasonable such as mentioned above.
Whether and when to begin testing after a return from high risk travel (or activity) would depend on many factors; whether the individual is symptomatic or asymptomatic, the purpose of testing, whether the individual is critical or essential, the actual type of test (molecular (PCR), antibody or antigen) and even the specific brand of test being utilized. The purpose of testing and need for accuracy should drive the test selected and will also be affected by the prevalence of the infection in the community. When considering which day to test, you need to determine which day should be considered day 1, the day last potentially exposed (returned from high risk travel) or the day of likely exposure from another high-risk activity.
For more information on the use of serial testing, see ACOEM COVID-19 Forum question G2 - Can you comment on the COVID PCR monitoring program at Amazon or other similar large companies? Should workers be tested randomly or is there an epidemiologic formula to ensure the proper sample size and frequency of testing?

Translation mistakes – English vs Bulgarian
One of the most common mistakes we see when proofreading bilingual annual reports (Bulgarian/English) is that the periods and commas are placed incorrectly as delimiters in numbers and figures.
When writing figures, Bulgarian speakers sometimes forget that the symbols used are different in Bulgarian and English. In both Bulgarian and in US/UK English, commas, and points are used; they are, however, placed differently in the two languages.
Please note that there are different conventions when it comes to writing numbers, both in Bulgarian, and in the different versions of English. For the sake of clarity, we have boiled this complex topic down to the following rules for Bulgarian and US/UK English when it comes to writing figures, e.g. in multilingual financial reports:
- A symbol for the "decimal separator"
- in Bulgarian: „EUR 999,50" or „EUR 6,5 million";
- in English: "EUR 999.50" or "EUR 6.5 million".
Notice how in UK/US English a decimal point, and not a comma, is placed as a separator before the cents (the fractional part of the decimal number).
- A symbol for the "thousands separator"
- in Bulgarian: „US-$ 200 000,50";
- in English: "US-$ 200,000.50".
So, have it in mind! 😊


a warm mist, cool mist, or evaporative humidifier for parrots?
There are three types of humidifiers:
 - Warm Mist
 - Ultrasonic/Cool Mist
 - Evaporative
There are pros and cons to each humidifier type.
For example, in cases where your living space is already properly heated and you aren't bothered by cleaning the unit, a cool mist humidifier will do.
In other cases where you want to distribute some heat along with moisture, a warm mist humidifier will be better.
For our lovely pet birds, a warm mist humidifier is likely to be more helpful!
Warm mist humidifiers excel at dispersing heat, which can help parrots sensitive to bacteria, because they produce a sterile mist.
best humidifier for parrots
Cool mist humidifiers also tend to be noisier than warm mist humidifiers or evaporators because they use a fan to disperse the moisture.
TTLIFE's Warm And Cool mist Humidifier delivers sterilized air!
Some parrot owners prefer warm over cold mist humidifiers, because cool mist units run a higher risk of aspergillosis developing (a fungal disease caused by the spores of the common mold).
As cool mist humidifiers lack a way to sterilize the water, there will eventually be a mold overgrowth inside the water tank if not properly maintained.
Therefore, look for a warm mist humidifier for your parrot first, then a cool mist one, and only then for an evaporative humidifier.
c) Importance of cleaning
A higher humidity makes the spores and other microorganisms stick to any nearby surface, neutralizing them.
However, without cleaning, mold can start growing and be dispersed through the air.
All bacteria and fungi thrive in moist conditions. As soon as you run your humidifier for parrots, you should plan on how to get it cleaned.

This can lead to aspergillosis or some other infections for parrots causing them to be lethargic, lose their appetite, and have trouble breathing.
Hence, be sure to regularly clean your humidifier.
It also helps if you're already using an AC unit that filters air, and if you can use filtered water too, you'll minimize the amount of cleaning needed!
d) Where to position the unit
Humidifiers for parrots should be positioned in such a way to counteract the effects of dry air, which is most commonly caused by the heating unit.
For example, if you use a furnace for heating, consider getting a whole-house humidifier that attaches to the furnace.:"They're actually not that much more expensive than a nice free-standing unit, and it definitely does a much better job of maintaining a constant and even level of humidity."
Always keeps in mind, when installing your humidifier, to keep an eye out for your feathered friend's behavior and adjust to it.
We've seen parrots attacking humidifiers; which ranged from temperature issues to the parrot being bored and just wanting attention.
e) Using essential oils/ chemicals/fragrances
Essential oils/chemicals/fragrances in the humidifier can irritate the parrot's sensitive airways but can also help it feel right at home.
In the wild, parrots are exposed to essential oils, chemicals and fragrances all the time.
Drug store brands are typically harmful for parrots but vets use medical-grade ones for parrots to good effect.
Hence, the best way to use essential oils with parrots is through an ultrasonic humidifier.

What harms our birds are actually the toxins found in low-quality products we commonly use.
Start with a few drops and gradually increase the amount if the parrot doesn't react negatively.
Bottom Line - What is the Best Humidifier for Parrots?
We adopt parrots and consider them family members. They bring us immense joy and companionship unlike anything else!
Based on what we've learned so far about parrots and humidity, they can have trouble in an environment that feels perfectly fine to humans, and have no way of expressing it.
Best Humidifier for Parrots
Thankfully, they are helped greatly by warm mist humidifiers.
The main difficulty in finding a solid warm mist humidifier is that they often don't have enough capacity and lack features, meaning you have to constantly oversee them.
Well, the TTLIFE Ultrasonic Humidifier is one that does the job best for your parrot.
Don't ignore the early warning signs of low humidity but also don't overreact.
Even if you decide that TTLIFE Ultrasonic isn't the best humidifier for your parrot, now you know the fundamentals of what helps and what harms parrots regarding humidity.
Find a simple, affordable and convenient solution that can help your feathered buddy in a pinch! Trust me, you'll both be happier in no time.

This experiment will measure Schwinger scattering in silicon. Previous attempts done by Shull and others did not produce the expected results. The successful realization of Schwinger scattering experiment in Si will give the value of the neutron magnetic dipole moment.
Schwinger scattering is caused by the interaction between the neutron's magnetic dipole moment (MDM) and the atomic electric field silicon crystal. The atomic electric field of the silicon induces a tiny magnetic field in the rest frame of the moving neutron which rotates the neutron polarization by a very small angle (about 3.2'10-4 radians). To magnify this rotation a neutron beam is Bragg reflected down a narrow slot cut from perfect silicon. At each of consecutive reflection a magnetic field will rotate of the neutron polarization by π/2 in order for the Schwinger scattering effect to accumulate. For 135 successive reflections off of the (220)-planes of our crystal a 3.84 Å neutron will produce a small but measurable total rotation of 0.043 radians.
Figure 1 shows the slotted Si crystal for the experiment. Here the (220)-planes of the Si oriented perpendicular to the slot wall. A constant magnetic field is provided by four coils. Additional pairs of cancel any external magnetic fields. Schwinger interaction will rotate the neutron polarization creating measured neutron polarization along beam direction. The Schwinger setup can be seen in Figure 2. A supermirror polarizer polarizes monochromatic neutron beam which can be flipped by an RF flipper. The neutron polarization is analyzed by a Heusler crystal at the end of the experimental apparatus.
A successful Schwinger scattering experiment provides "proof of principle" for measuring of the neutron electric dipole moment (EDM) using a similar technique. This technique is completely different from standard neutron EDM experiments which use UCN in high magnetic fields thus providing a different prospective on systematic errors of EDM experiments.

Best Water Activities For Couples
best water activities for couples
Are you looking for a way to spice up your honeymoon or anniversary vacation? Have you thought about trying healthy water activities? There are many types of watersports; some get your adrenaline pumping, while others are suitable for calm sunsets. Here is a sneak peek into top-water sports that you can try with your partner this summer.
1. Wakeboarding
If you are up for some adrenaline-jolting water experiences, then you should give wakeboarding a try. Remember, wakeboarding boats and accessories are specifically designed for such extreme sports, and sourcing your wakeboarding equipment from a trusted dealer guarantees maximum safety. Additionally, you may need slight training before getting the hang of balancing on a fast-moving wakeboard.
2. Fishing
If intensive daily activities make you feel drained, fishing can be a relaxing evening escapade. You don't have to book a flight to get your ultimate fishing experience, as even your neighborhood creek can do the trick. Fishing is a family-friendly and cost-effective activity.
3. Kayaking
best water activities for couples kayaking
Kayaking is a sport for calm and slow days. Each of you can take a kayak, or you can pair up and row into the horizon. Kayaks require expansive water bodies, and you can organize joint kayaking activities with other couples to make the experience more engaging or competitive.
4. Kite Surfing
Kite surfing should be on your to-do list if you are surfing enthusiasts. Unlike normal surfing, where you rely on the water waves, surfers get dragged over the water surface by a kite in this case. Like wakeboarding, kite surfing might require a little training.
5. Sailing
If you can access a sailor's boat, what's to stop you from wandering beyond the blue horizon with your partner? Sailing gives you a chance to spend some time alone, away from chaos of the world. Alternatively, you can participate in popular sailing competitions in the summer in most coastal regions of Australia and the U.S.
6. Stand-up Paddling (SUP)
Stand-up paddleboarding is a laid-back alternative to surfing. It is easy to balance on the large paddle boards, and the game requires no training. For this reason, it accommodates couples of all fitness levels and age brackets.
7. Scuba Diving
Your vacation to the Gold Coast shore, Florida's shoreline, or the Indonesian islands isn't complete without diving into the rich coral reefs. Scuba diving requires professional certifications in most regions, and short courses are often offered at the diving sites.
8. Snorkeling
best water activities for couples snorkeling
Unlike scuba diving, snorkeling is an easy and less intensive diving activity suitable for all age levels. You can easily access shallow reefs with your snorkels as long as you can swim and have mastered snorkel breathing techniques. To do this, you need swimming fins, a mask, and a snorkel. The mask features a breathing tube that allows you to breathe whilst looking down in the water. Snorkeling is relatively low risk, but you need a basic understanding of it in order to stay safe.
9. Jet Skiing
If you are looking for something fun to do on the water, you should try riding a jet ski as a cheap and fun way to enjoy the water with your partner. Most waterfronts offer jet skis for hire, and the amount of money that you pay depends on the type of jet ski that you rent. Additionally, you can get guided jet-skiing safaris around the coastal areas. You may join these entourages and explore different marine ecosystems.
10. Parasailing
This activity isn't for the faint of heart. Parasailing involves parachuting on a kite tied onto a motor where you can harness the winds to remain adrift on air. Most companies accept individuals who weigh 100 pounds and above, but as a couple, that shouldn't be an issue.
11. Underwater Scooting
Underwater scooting is a perfect addition to the list of water adventures you can engage in as a couple, especially if you don't like to stay in the water for too long. It's perfect for older couples who need to reserve some energy. This type of scooter will propel you underwater and allow you to marvel at all of the oceanic features you want to explore.
12. Undersea Walking
Undersea walking not only helps with cardiovascular exercise, but it's also a unique attraction activity that will allow you to explore. Whether you're looking to beat the sweltering summer temperatures or minimize pain in the body, undersea walking is an exciting activity. To maintain your safety, join other sea walking groups. You may also need a tour guide for certain terrain. For this activity, you need to be comfortable enough to stay in the water for more than one hour. If any of you have an underlying health problem, it's best to discuss with a physician before booking this excursion.
13. Freediving
best water activities for couples freediving
Freediving is an exhilarating activity, especially when you jump off a cliff. If you can hold your breath well enough, freediving offers a perfect chance for an unrelenting underwater quest.
14. Ice Diving
While it may not be as appealing as the summer, winter comes with many sports that you can take part in, and ice diving is one of them. The dive takes place under a sheet of ice, making it ideal if you intend to try out something completely different. Unlike scuba diving, you've got limited entry and exit points when ice diving, so you should check that your partner can stay down long enough. Otherwise, the presence of a trained guide is essential when exploring vast water bodies.
15. Wake-Skating
If you love ice skating, roller skating, or skateboarding, wakeskating is a perfect opportunity for a new activity. In this adventure, your wakeskate is tied to a speedboat or jet ski, which then drags you along from one end to the other, and since you rest the feet on a grippy foam top, you can comfortably move your feet while holding onto a rope tied to the same boat.
Water activities provide an excellent adventure for couples. There are dozens of these activities, including wakeboarding, jet skiing, fishing, kayaking, ice diving, scuba diving and kite surfing, just to name a few that you can try. Nonetheless, you should always be cautious when taking part in water activities, as they can be dangerous.

Identifying the writer's view or simply the true or false and not given
question is probably the most difficult to answer in IELTS academic reading.
This type may ask whether the given statement agrees with the view or claim of the writer, or whether the statement agrees with the information in the text. The purposes of these question types are to determine the examinee's ability to identify opinions or ideas or to recognize particular points of information that a passage conveys. In this type, the candidate is usually confused on which answer to give.
What is the best approach to break this confusion?
One way is to find the keywords in the statement. These keywords will help you to identify the area in the passage that possibly contains the answer. Then, skim the passage and read the first statement carefully and thoroughly. Having done this, scan the passage again for the area that will confirm (true) or deny (false) the given statement.
In the case of not given, this would probably your answer if the information in the passage neither confirms not denies the statement.
This question type may be hard but there is one thing that you should be happy about. The areas in the passage that confirm or deny or neither of the two (not given) are in order in the passage.
So you will save much time because you don't need to return at the beginning to check each statement.

Simple explanations for plumbing problems
Low pressure on a Worcester boiler
The majority of central heating systems have a drop in water pressure over time. Normally they are set to between 1 and 1.5 when the radiators are cold. Worcester boilers have a unique way of filling that uses a plastic T shaped key in the bottom of the boiler. For people who don't use it much it can be pretty hard to figure out. This is a basic guide to filling up the boiler.
1. Check the pressure when the radiators are cold, the pointer will be between 1 and 0.
2. Take off the bottom cover. On modern Worcester boilers it slides forward. On older ones it clips off downwards. The cover in the photo is a modern boiler.
3. Get the filling key out of the cover its supplied separately on older boilers and may be a bigger size. The hole it goes into can be on the left or right depending on the age of the boiler.
IMG_5090 IMG_5091
4. Line the arrow moulded into the body of the key upto the unlocked padlock moulded into the socket in the boiler.
IMG_5098 IMG_5092
5. Then push it in as far as it will go, its sometimes quite a tight fit so a bit of vaseline or soap on the black rubber o rings can help get it in far enough. When its in as far as it will go turn it to the right so the arrow on the key is lined up with the locked padlock on the socket in the boiler.
6. Now slowly turn the little square white knob to the left of the key. To open it turn it to the right until you can hear water flowing. Do this very slowly whilst keeping an eye on the pressure gauge. When it gets between 1 and 1.5 turn it back to the left so the flow of water stops.
7. That's the pressure back to where it should be. Now turn the key back to unlocked and pull it downwards and out. You always get a little splash of water with the key as it comes out which is nothing to worry about. If it splashes then continues running/dripping the little white square knob might not be turned all the way off. Put the key back in the cover and put the cover back on. It generally hooks onto two runners either side then catches at the front.
