Keyset-driven Cursors (Database Engine)
The membership and order of rows in a keyset-driven cursor are fixed when the cursor is opened. Keyset-driven cursors are controlled by a set of unique identifiers, keys, known as the keyset. The keys are built from a set of columns that uniquely identify the rows in the result set. The keyset is the set of the key values from all the rows that qualified for the SELECT statement at the time the cursor was opened. The keyset for a keyset-driven cursor is built in tempdb when the cursor is opened.
Changes to data values in nonkeyset columns (made by the cursor owner or committed by other users) are visible as the user scrolls through the cursor. Inserts to the database made outside the cursor are not visible in the cursor unless the cursor is closed and reopened. Inserts made through the cursor using an API function such as the ODBC SQLSetPos function are visible at the end of the cursor. @@FETCH_STATUS returns a "row missing" status when an attempt is made to fetch a row deleted after the cursor was opened. An update to a key column operates like a delete of the old key value followed by an insert of the new key value. The new key value is not visible if the update was not made through the cursor; it is visible at the end of the cursor if the update was made through the cursor using either an API function such as SQLSetPos or the Transact-SQL WHERE CURRENT OF clause and the SELECT statement did not contain a JOIN condition in the FROM clause. The new key value is not visible if the insert contained a remote table in the FROM clause. Attempts to retrieve the old key value get the same missing row fetch status as a deleted row.
An index on computed columns cannot be used when declaring a keyset-driven cursor on a remote table. You can create another index to provide the unique keys for that remote table.

Today's Law, Society, and Taxation panels at the virtual 2021 Law & Society Association Annual Meeting (program):
Session #6: Tax, Politics, and History (Diane Klein (Chapman), Chair/Discussant):
Tax law is a product of the political process and often depends in large part on the views of the society in which it is to be enacted. Further, the particular nature of that society influences how the tax law develops and how it is applied in practice. This makes tax history a critical part of the understanding of the tax law. The papers in this session reflect on the role that society plays in the development of some particular areas of the tax law, and the role that the tax law plays in the evolution of society.
Session #7: Tax, Inequality, and Racial Justice (Shu-Yi Oei (Boston College), Chair/ Discussant):
Rising awareness of racial injustice and broader concerns regarding social inequality have dominated national conversations in recent years. This panel focuses on tax law's long history with inequalities along race and gender lines, as well as attempts to address inequality through the tax code.

Session #8: Tax Practice and Interpretation (Sloan Speck (Colorado), Chair/ Discussant):
Tax law requires interpretation, and statutes are just the starting point for deciding what consequences the tax law brings. The papers on this panel consider the language of the tax law in its context, and discuss what's at stake in the act of interpretation.

Total Character of a group $G$ with $(G,Z(G))$ as a generalized Camina pair
We investigate whether the total character of a finite group $G$ is a polynomial in a suitable irreducible character of $G$. When $(G,Z(G))$ is a generalized Camina pair, we show that the total character is a polynomial in a faithful irreducible character of $G$ if and only if $Z(G)$ is cyclic.

Character Degree Graphs of Solvable Groups of Fitting Height $2$
Given a finite group $G$, we attach to the character degrees of $G$ a graph whose vertex set is the set of primes dividing the degrees of irreducible characters of $G$, and with an edge between $p$ and $q$ if $pq$ divides the degree of some irreducible character of $G$. In this paper, we describe which graphs occur when $G$ is a solvable group of Fitting height $2$.

Degree Homogeneous Subgroups
Let $G$ be a finite group and $H$ be a subgroup. We say that $H$ is \emph{degree homogeneous }if, for each $\chi\in \Irr(G)$, all the irreducible constituents of the restriction $\chi_{H}$ have the same degree. Subgroups which are either normal or abelian are obvious examples of degree homogeneous subgroups. Following a question by E.~M. Zhmud', we investigate general properties of such subgroups. It appears unlikely that degree homogeneous subgroups can be characterized entirely by abstract group properties, but we provide mixed criteria (involving both group structure and character properties) which are both necessary and sufficient. For example, $H$ is degree homogeneous in $G$ if and only if the derived subgroup $H^{\prime}$ is normal in $G$ and, for every pair $\alpha,\beta$ of irreducible $G$-conjugate characters of $H^{\prime}$, all irreducible constituents of $\alpha^{H}$ and $\beta^{H}$ have the same degree.

Beavers and sea otters are known for having this amazing fur that traps air when they dive underwater, helping to keep their little blubber-less bodies warm. This is what inspired MIT engineers to create a fur-like rubbery pelt. They wanted to figure out how these mammals star warm and even dry while diving in and out of icy waters.
The Plan: Make precise, fur-like surfaces of various dimensions, dunk the surfaces in liquid at different speeds, and use video imaging to measure the air that is trapped in the fur during each each dive.
"We are particularly interested in wetsuits for surfing, where the athlete moves frequently between air and water environments," says Anette (Peko) Hosoi, a professor of mechanical engineering and associate head of the department at MIT. "We can control the length, spacing, and arrangement of hairs, which allows us to design textures to match certain dive speeds and maximize the wetsuit's dry region."
The team at MIT made several molds by laser-cutting thousands of tiny holes in small acrylic blocks. Each mold was altered, varying in size and the spacing of individual hairs. The molds were then filled with a soft casting rubber.
Researchers mounted each hairy piece of rubber and submerged them in silicone oil. They chose oil so they could better observe any air pockets forming.
Results: The team learned that the spacing of individual hairs, and the speed at which they were plunged, played a large role in determining how much air a surface could trap. Surfaces with denser fur, plunged at higher speeds, generally retained more air within the hairs.
So, what does this mean? If you've ever worn a wetsuit you know they can be heavy and hard to move around in. Let's pretend a wetsuit is made out of this fabricated hairy material, using air for insulation instead of soggy rubber. The bio-inspired wetsuit would be lightweight and behave better in water.
Can you imagine? Light, warm, furry wetsuits? I'm in! 🏄
The results were published in the journal Physical Review Fluids. You can view the study here -along with some pretty epic charts, diagrams, and photos.

How we sold more sports water by using music to put people in the zone
Increase sales of Mizone Formulated Sports Water by 10% despite a 20% decline in the overall category.
Music has the power to take you to another state of consciousness – a place where physical effort feels easier and you perform better. This place is often known as 'the zone'. So we went on a quest to create 'music to put you in the zone'.
1. We enlisted an Olympic sports psychologist, four music producers and four everyday athletes.
2. We created 'The ZoneLab' and conducted a series of musical experiments to discover what kind of music puts people in the zone.
3. We produced four ZoneLab-tested music tracks and distributed them on bottles as a gift with purchase.
4. We shared the ZoneLab story through PR and video content that followed the creation and testing of each music track.

Determine Image Quality with Photoshop CS5 Histograms
Before making image adjustments, look at the image's histogram, which displays an image's tonal values, to evaluate whether the image has sufficient detail to produce a high-quality image. In Photoshop CS5, choose Window→Histogram to display the Histogram panel.
The greater the range of values in the histogram, the greater the detail. Poor images without much information can be difficult, if not impossible, to correct. The Histogram panel also displays the overall distribution of shadows, midtones, and highlights to help you determine which tonal corrections are needed.
A full histogram indicates a smooth transition from one shade to another in the image. When a histogram is spread out and has gaps in it, the image is jumping too quickly from one shade to another, producing a posterized effect. Posterization is an effect that reduces tonal values to a limited amount, creating a more defined range of values from one shade to another.
If you have a bad histogram, we recommend that you rescan or reshoot the image. Make sure your scanner is set for the maximum number of colors.
If you have a good histogram to start with, keep it that way by not messing around with multiple tone correction tools. Most professionals use the Curves feature — and that's it. Curves (choose Image→Adjustments→Curves) adjusts levels (brightness and contrast) and color balance, all in one step.
If a Warning icon appears while you're making adjustments, double-click anywhere on the histogram to refresh the display.
Don't panic if your histogram is smashed all the way to the left or right. The bars of the histogram represent tonal values. You can break down the types of images, based on their values, into three key types:
High key: An extremely light-colored image. Information is pushed toward the right in the histogram. Color correction has to be handled a little differently for these images to keep the light appearance to them.A high key image is a light image.
Low key: An extremely dark image. Information is pushed to the left in the histogram. This type of image is difficult to scan on low-end scanners because the dark areas tend to blend together with little definition.A low key image is a dark image.
Mid key: A typical image with a full range of shades. These images are the most common and easiest to work with.A typical image with a full range of values is a mid key image.

A History of Style: Fashion Inspired by Josephine Baker
When you think of a fashion icon from the past, who is the first person that comes to mind? Marilyn Monroe? Audrey Hepburn? Edie Sedgwick, maybe? While all three of those females have enviable styles that we absolutely love, there are so many other fashionable ladies that have graced the history pages. This biweekly column focuses on just that: unexpected and out-of-the-box fashion icons from the past. We feature girls who have not only created an influence, but also have distinct signature types that we can still draw inspiration from nowadays.
If you haven't observed them already, be confident to check out our other "A History of Style" posts on Amelia Earhart, Billie Holiday, Joan Jett, Louise Brooks, Dorothy Dandridge, Elizabeth Taylor, Edith Head, Mary Tyler Moore, Sylvia Plath, Edith Bouvier Beale, Marlene Dietrich, Frida Kahlo, Cyndi Lauper, Isadora Duncan, Pam Grier, C. Z. Guest and Debbie Harry.
This week, we'll be taking a closer look at entertainer Josephine Baker's bold, glam and totally revolutionary sense of style. Read on to learn far more about Josephine's life and unique style, then check out some outfit tips to aid you channel her look for yourself:
five Facts About Josephine Baker
- Josephine Baker was born Freda Josephine McDonald on June 3rd, 1906 in St. Louis, Missouri. After performing in chorus lines in St. Louis and Harlem, she moved to Paris in 1925 and rapidly gained fame due to her bold dancing and brazen costumes.
- Josephine had a pet cheetah named Chiquita who she employed to take for walks along the streets of Paris. Chiquita even had a fabulous diamond-encrusted collar. (Lucky cat!)
- For the duration of Planet War II, Josephine worked as a spy for the French resistance. She relayed data overheard among German officers during her performances and exposed French officials secretly working for the Germans. It was also rumoured that she smuggled secret documents written in invisible ink on her sheet music. After the war, Josephine was awarded the Croix de guerre (the French military honor) for her service.
- Josephine was a strong supporter of the American Civil Rights Movement and racial equality. More than the course of her life, she adopted two daughters and ten sons of various nationalities and races. She referred to her household as an "experiment in brotherhood" and the "Rainbow Tribe."
- In 1975, Josephine celebrated 50 years in show enterprise with a retrospective revue in Paris. Just four days after the show, Josephine suddenly passed away due to a cerebral hemorrhage. She was the 1st American woman to receive full French military honors at her funeral.
Josephine's Style 101
- Art Deco. Josephine's success occurred alongside the rise of the Art Deco movement in Paris, so naturally, her style was influenced by that time period and vice versa. Sleek lines and geometrc shapes are the epitome of Art Deco and Josephine acted as a muse for the movement with every thing from her clothing selections to her slicked-down hairdos. Spend tribute to Josephine by rocking a few pieces of Art Deco-inspired jewelry, or attempt some fun Art Deco nail art.
- Wild side. Josephine also had a bold and entirely fearless sense of style. Who else could perform in small much more than a skirt created out of bananas (yes, bananas) and make it look great?! The next time you are wary of testing out a bold new trend, take a cue from Josephine and just go for it.
- Accessories overload. When it comes to accessories, we usually try to follow that age-old adage "less is more," but in Josephine's eyes, a lot more was definitely more. She paired ropes of pearls, door-knocker earrings and oversized cocktail rings together and always looked glamorous and not at all over-the-best. And of course, no Josephine-inspired look would be total without having an elaborate hair accessory. Attempt a turband or jeweled headpiece for a modern day day interpretation.

Relaxed Parsing of Regular Approximations of String-Embedded Languages
We present a technique for syntax analysis of a regular set of input strings. This problem is relevant for the analysis of string-embedded languages when a host program generates clauses of embedded language at run time. Our technique is based on a generalization of RNGLR algorithm, which, inherently, allows us to construct a finite representation of parse forest for regularly approximated set of input strings. This representation can be further utilized for semantic analysis and transformations in the context of reengineering, code maintenance, program understanding etc. The approach in question implements relaxed parsing: non-recognized strings in approximation set are ignored with no error detection.

Nissan demonstrates sweat-sensing seats to fight dehydration
Sweat-covered seats aren't most people's idea of a good thing, but Nissan thinks they are. The Japanese automaker is demonstrating technology that changes the color of car seats and steering wheels based on sweat. Nissan believes this will allow the car to detect when the driver is dehydrated.
Nissan designer Paulien Routs, and Droog Design sought to show how useful sweat can be with the Nissan Juke Soak. That last part refers to the trademarked, sweat-sensitive textile material the car's interior is coated with. You can see exactly how it works in the embedded video. Soak can also be sprayed onto clothes to give the wearer a better idea of his or her hydration level, which could be particularly useful when working out.
While the concept of car seats that change color from sweat may seem a bit silly, Nissan claims driver dehydration is no laughing matter. The automaker contends that dehydration has as big an impact on reaction times and overall alertness as drunk driving. That's based on a 2015 study conducted by England's Loughborough University, and funded by the European Hydration Institute, a research organization that promotes hydration.
Staying hydrated should be as important for driving as it is for any other activity, but car buyers may not be interested in seats that change colors when they sweat. Besides being a bit undignified, it's also sort of an inefficient way to let drivers know they might be dehydrated. The color changes won't be highly apparent if you're sitting in the seat, after all. Drivers may also simply ignore the car's warning about their hydration levels. Given the number of warnings and alerts modern cars are capable of emitting, that wouldn't be difficult.
But the Nissan Juke Soak is a reminder that drivers need to do their part to keep the roads safe. A driver must be calm, alert, and awake at all times, something that is easy to forget in an age where driving is taken for granted. Everyone is responsible for making sure they are fit to drive before getting behind the wheel. That is, at least until autonomous cars arrive.

Frequently Asked Questions
How does the compiler handle converting between bytes and words?
In an assignment such as:
bytevar = wordvar;
The most significant BYTE is lost. This is the same result as:
bytevar = wordvar & 0xff;
The following will yield just the most significant BYTE: For Example:
bytevar = wordvar >> 8;
Any arithmetic or relational expression involving both bytes and words will perform word operations, and treat the bytes as words with the top byte 0. For example:
wordvar= 0x1234;
bytevar= 0x34;
if(wordvar==bytevar) //will be FALSE
Any arithmetic operations that only involve bytes will yield a byte result even when assigned to word.
bytevar1 = 0x80;
bytevar2 = 0x04;
wordvar = bytevar1 * bytevar2; //wordvar will be 0
However, typecasting may be used to force word arithmetic:
wordvar = (long) bytevar1 * (long) bytevar2; //wordvar will be 0x200

CALGARY -- Fewer Albertans intend to turn down vaccination against COVID-19 compared to stated intentions tabulated prior to the arrival of vaccines in the province.
Saskatchewan now has the highest level of vaccine hesitancy in Canada at 24 per cent. The other provinces range between 10 and 12 per cent according to the poll.
"Measles, you probably need 90-95 per cent coverage," says Dr. Jia Hu with the University of Calgary's Cumming School of Medicine.
"You can still have breakthroughs, little outbreaks every once in a while, but it doesn't rule our lives. We will have the supply, if people get immunized we will reach herd immunity.
"Our trajectory is not there yet, but that's why we need to do as much as we can to try and get it higher."
Hu says the two most common reasons for reluctance is either a lack of concern for the virus' ability to hurt them, or a lack of trust in government regulators and the speed of vaccine development.
While many cases of COVID-19 are indeed mild, each case is like a lottery ticket, with some people experiencing severe, lingering illness.
Even young healthy Albertans have died. There are no sure predictors who will become severely ill.
More than 2.2 million doses of vaccine have been given in the province with less than 350 of those experiencing adverse reactions.
Hu says despite clear data that COVID-19 has a vastly greater chance of hurting a person, that's often not enough to overcome a person's resistance.
"We still need to have those conversations in sort of gentle, accepting way," he said.
The Angus Reid Institute's online survey of 1,594 Canadian adults was conducted over three days beginning April 20. The margin of error for a survey of a similar sample size is considered to be +/- 2.5 percentage points.

To replace a textbox by a picturebox, you can use 3 different types of tokens :
Each of the above will replace the textbox in which it is, by a picturebox.
-All other tokens within that textbox will be ignored, if a graphics file is associated with the token for the current textbox (this is not necessarily the case).
-If no graphics file is associated with an image token for the current textbox, then the textbox is not changed to a picturebox, and all other tokens included in that textbox are evaluated normally.
-However zap tokens supercede all other tokens and, in a textbox which includes both zap and image tokens, if the zap token evaluates to a result which deletes the textbox, then that textbox will be deleted, regardless of the result of the image token.

Healthcare Workers
Understand the role of healthcare workers in a town.
0-30 min.
Tell the children they will explore what it is like to be a healthcare worker.
Explain that doctors, nurses, and dentists are called "healthcare workers," and that they help us stay healthy. Tell
the children that when all of the parts of your body are working as they should, you are healthy.
Tell the children that people go to doctors and dentists for different reasons. Sometimes they go to receive medical care, or help for health problems. Other times, people go to doctors and dentists for checkups. A checkup is an
appointment where a healthcare worker checks a person's body or teeth to see if everything is okay. Explain that healthcare workers use tools such as lights, tongue depressors, stethoscopes, scales, measuring tapes or sticks, blood pressure cuffs, thermometers, suction straws, etc.
Explain that people also go to hospitals to receive care. Many mothers give birth, or have their babies in a hospital. The nurses and doctors check the mothers and babies to make sure they are healthy.
Show the photographs of the LEGO® DUPLO® models for Activity 4.
Consider asking questions like:
 - Have you ever been to the hospital, doctor's office, or dentist's office? If so, why
 were you there? Who worked there?

the consistency of the object data.
For a SQL representation, the USING clause must specify either SQLData or ORAData, and the corresponding Java class must implement one of those interfaces. The EXTERNAL NAME clause for attributes is optional.
Creating SQLJ Object Types
The SQL statements to create SQLJ types and specify their mappings to Java are placed in a file called a deployment descriptor. Related SQL constraints and privileges are also specified in this file. The types are created when the file is executed.
Below is an overview of the process of creating SQL versions of Java types/classes:
 1. Design the Java types.
 2. Generate the Java classes.
 3. Create the SQLJ object type statements.
 4. Construct the JAR file. This is a single file that contains all the classes needed.
 5. Using the loadjava utility, install the Java classes defined in the JAR file.
 6. Execute the statements to create the SQLJ object types.
Additional Notes About Mapping
The following are additional notes to consider when mapping of Java classes to SQL types:
 - You can map a SQLJ static function to a user-defined constructor in the Java class. The return value of this function is of the user-defined type in which the function is locally defined.
 - Java static variables are mapped to SQLJ static methods that return the value of the corresponding static variable identified by EXTERNAL NAME. The EXTERNAL NAME clause for an attribute is optional with a SQLData or ORAData representation.
 - Every attribute in a SQLJ type of a SQL representation must map to a Java field, but not every Java field must be mapped to a corresponding SQLJ attribute: you can omit Java fields from the mapping.
 - You can omit classes: you can map a SQLJ type to a non-root class in a Java class hierarchy without also mapping SQLJ types to the root class and intervening superclasses. Doing this enables you to hide the superclasses while still including attributes and methods inherited from them.
 However, you must preserve the structural correspondence between nodes in a class hierarchy and their counterparts in a SQLJ type hierarchy. In other words, for two Java classes j_A and j_B that are related through inheritance and are mapped to two SQL types s_A and s_B, respectively, there must be exactly one corresponding node on the inheritance path from s_A to s_B for each node on the inheritance path from j_A to j_B.
 - You can map a Java class to multiple SQLJ types as long as you do not violate the restriction in the preceding paragraph. In other words, no two SQLJ types mapped to the same Java class can have a common supertype ancestor.
 - If all Java classes are not mapped to SQLJ types, it is possible that an attribute of a SQLJ object type might be set to an object of an unmapped Java class. Specifically, to a class occurring above or below the class to which the attribute is mapped in an inheritance hierarchy. If the object's class is a superclass of the attribute's type/class, an error is raised. If it is a subclass of the attribute's type/class, the object is mapped to the most specific type in its hierarchy for which a SQL mapping exists
See Also:
The Oracle Database JPublisher User's Guide for JPublisher examples of object mapping
Evolving SQLJ Types
The ALTER TYPE statement enables you to evolve a type by, for example, adding or dropping attributes or methods.
When a SQLJ type is evolved, an additional validation is performed to check the mapping between the class and the type. If the class and the evolved type match, the type is marked valid. Otherwise, the type is marked as pending validation.
Being marked as pending validation is not the same as being marked invalid. A type that is pending validation can still be manipulated with ALTER TYPE and GRANT statements, for example.
If a type that has a SQL representation is marked as pending evaluation, you can still access tables of that type using any DML or SELECT statement that does not require a method invocation.
You cannot, however, execute DML or SELECT statements on tables of a type that has a serializable representation and has been marked as pending validation. Data of a serializable type can be accessed only navigationally, through method invocations. These are not possible with a type that is pending validation. However, you can still re-evolve the type until it passes validation.
See Also:
"Type Evolution"
For SQLJ types having a SQL representation, the same constraints can be defined as for ordinary object types.
Constraints are defined on tables, not on types, and are defined at the column level. The following constraints are supported for SQLJ types having a SQL representation:
 - Unique constraints
 - Primary Key
 - Check constraints
 - NOT NULL constraints on attributes
 - Referential constraints
The IS OF TYPE constraint on column substitutability is supported, too, for SQLJ types having a SQL representation.
Querying SQLJ Objects
SQLJ types can be queried just like ordinary SQL object types. Methods called in a SELECT statement must not attempt to change attribute values.
Inserting Java Objects
Inserting a row in a table containing a column of a SQLJ type requires a call to the type's constructor function to create a Java object of that type.
The implicit, system-generated constructor can be used, or a static function can be defined that maps to a user-defined constructor in the Java class.
Updating SQLJ Objects
SQLJ objects can be updated either by using an UPDATE statement to modify the value of one or more attributes, or by invoking a method that updates the attributes and returns SELF—that is, returns the object itself with the changes made.
For example, suppose that raise() is a member function that increments the salary field/attribute by a specified amount and returns SELF. The following statement gives every employee in the object table employee_objtab a raise of 1000:
UPDATE employee_objtab SET c=c.raise(1000);
A column of a SQLJ type can be set to NULL or to another column using the same syntax as for ordinary object types. For example, the following statement assigns column d to column c:
UPDATE employee_reltab SET c=d ;
Defining User-Defined Constructors in Java
When you implement a user-defined constructor in Java, the string supplied as the implementing routine must correspond to a static function. For the return type of the function, specify the Java type mapped to the SQL type.
Here is an example of a type declaration that involves a user-defined constructor implemented in Java:
( name VARCHAR2(30),
 age NUMBER,
 RETURN Person1_typ AS RESULT

New mothers and babies could be at risk of contracting Legionnaires' disease from some pre-heated birthing pools, the government has warned.
Birthing pools filled in advance of the expected date of delivery are dangerous and are to be avoided, the warning from Public Health England states.
In 2014, a new born baby in England was found to have contracted Legionnaires' disease following a home birth in a pre-heated birthing pool.
Legionnaires' is a serious and sometimes fatal lung infection caused by inhaling the Legionella bacteria when suspended in water droplets.
Expectant mothers are advised to discuss matters with their midwife
Symptoms can materialise as rapidly as after two days after exposure and are usually flu-like, such as coughing, shortness of breath and chest pains.
Legionella bacteria grow in stagnant water between 20C and 45C, especially where nutrient rich rust, sludge, scale, sediment and algae are present.
If the water temperature of a birthing pool has been maintained for an extended time before birth by the use of a heater and circulation pump, this allows for conditions where Legionalla bacteria can grow.
Traditional birthing pools are filled with water once the pregnant woman goes into labour are considered to be safe. These come with disposable liners and the water is not kept warm using a heater.
One of the new birthing pools at East Surrey Hospital
Fixed birthing pools in NHS units are also considered safe as they are subject to stringent infection control procedures which prevent Legionella growing in the water and system.
Pregnant women are advised to discuss with their midwives if they are planning to use a birthing pool at home and have any concerns.
Midwives will be able to talk through the birth plan and give advice on how best to keep both mother and baby safe.

Comments on the Chatfield Reallocation Mitigation Company's Open House, May 30, 2017
From the Audubon Society of Greater Denver
The Proposed Mitigation is Better, But Our Basic Concerns Remain
In a 2.5 hour session on the evening of May 30, 2017, the entity known as the Chatfield Reallocation Mitigation Company presented current plans for mitigation of the Chatfield Reallocation project. It was a very slick presentation with good visuals and experts to answer questions, and it answered some of the concerns we have voiced for years. However, there was no opportunity for the public to submit comments.
- More of the mitigation will occur in Chatfield State Park.
- Wetlands mitigation has been moved from the uplands into the riparian zones.
- Severe downcutting on Plum Creek will be addressed.
However, our basic concerns remain:
- There will be a net loss of habitat, since what is destroyed at Chatfield State Park will not be replaced; the off-site conservation easements protecting riparian habitat protect EXISTING areas and no new riparian habitat is being created.
- There will be a net loss of accessible recreation lands. We will lose riparian areas and lake shore in Chatfield State Park that are open to the public to inundation or conversion to mud flats; the mitigation lands put into conservation easements will not be open to the public.
- The Corps of Engineers has refused to consider less-damaging practicable alternatives.
- The Corps has manipulated the project documents to avoid compliance with the Clean Water Act's requirement that they choose "the least environmentally damaging practicable alternative." Instead, they chose the MOST damaging.
- The Corps has determined that the "dependable" yield of the project – how much water it will provide in severe drought years – is 0. We fail to see why so much money should be spent for a project that cannot deliver a dependable yield.
- Because the providers have very junior water rights, they will only be able to store additional water in Chatfield 3 years out of 10, according to the Corps of Engineers' calculations. Most of the time the fluctuation zone will be dry with great possibilities for dust and noxious weeds.
- There is still uncertainty about the fate of the mature cottonwoods in the Park.
The visuals for the recreational mitigation have been posted on _URL_. As of June 5, the environmental mitigation visuals, the schedule of work and the Ecological Function Unit calculations used to plan the environmental mitigation had NOT been posted for future reference.

Doctor of Business Administration
Sydney Business School
Manatsa, Augustine, Dynamic capabilities, institutions and firm performance of firms responding to climate change: the case of Australia and South Africa, Doctor of Business Administration thesis, Sydney Business School, University of Wollongong, 2017. _URL_
Limited research has evaluated how the adoption of proactive climate change strategies impacts firm performance, more so a good understanding of the organisational components that link such strategies to performance. For this reason, the relationship between climate change strategies and other corporate strategies and how they could enhance firm performance is not well understood. In this study, organisational capabilities that underlie a firm's ability to generate and enhance performance by adopting proactive climate change strategies is pursued. The study develops and tests a model of dynamic capabilities enhancing firm performance through the development of proactive climate change strategies. Results from a survey of 166 energy and materials (E&M) firms, archival data and eight semi-structured interviews strongly support the model.
To investigate this relationship, this study identifies the dynamic capabilities and climate change practices of energy and materials (E&M) firms in Australia and South Africa. Given, the location differences, the study further explored the relationship between institutional capacity, proactive climate change practices, and firm performance. The investigation was guided by three objectives, with data obtained from archival and primary data sources. The primary data is obtained via an online survey and semi-structured interviews targeting company executives from eight purposefully sampled firms (four from each country).
The results reveal that South African firms have higher climate change proactiveness compared to Australian firms, although climate change proactiveness was moderate overall (r= 0.522; p< 0.001). In this regard, South African firms are more actively seeking to collaborate, develop partnerships and report their climate change practices than Australian firms. Regarding the extent of the presence of dynamic capabilities, absorptiveness was the most demonstrated in both countries, followed by adaptiveness and lastly innovativeness. Australian firms are more receptive to innovativeness compared to South African firms which focused on knowledge acquisition (a component of absorptiveness).
The study finds that as individual components, the dynamic capabilities impact on firm performance varies by component. As a construct, dynamic capabilities have no significant direct impacts on firm performance. Instead, proactive climate change practices strongly mediate the dynamic capabilities construct and performance. Climate change proactivity is, therefore, an important competence for E&M firms that seek to enhance their performance when faced by climate change disruptions. The presence of institutions has a weak influence on dynamic capabilities development, but strongly impact the climate change proactivity of participating firms. Therefore, the study finds that institutional presence indirectly influences the performance of firms.
The study contributes to "the beyond green" debate by linking climate change strategies and firm performance with studies that seek to rationalise proactive climate change practices. Previous studies had not considered that overall environmental proactivity was the major driver of the proactive strategies developed by such firms. Since the three dynamic capabilities were not incorporated in previous models, it is likely that the effect of climate change proactivity on firm performance was spuriously exaggerated. While the results show some significant relationships, the results could also be rather spurious given that both climate change proactivity and firm performance depend on firms' capabilities.
The study findings support existing literature but provide new knowledge specific to firms' capabilities and functional competencies that drive climate change practices and performance. Further research into the dynamic capabilities of proactive climate change practices of firms in more diverse countries and over a longer period is likely to extend this knowledge. Future research could also investigate the knowledge businesses require to identify and incorporate climate change risks into broader company risk management.

Gcode: Getting Started
G-coding K40-S & LaserWeb
Getting started with numerical coding languages......
G-code (or G programming language) is the street name for the most widely used numerical code programming language. Utilized mainly in automation, G-code is sometimes called G programming language. Very simply, G-code tells computerized machine tools - like laser systems - what to do and how to do it. For example, how fast to move, what path to take, etc.
M-code (for'miscellaneous function') is an auxiliary command; descriptions vary. Many M-codes call for machine functions like 'open workstation door,' which is why some say "M" stands for "machine", though it was not intended to.
A good starting point:
A good starting guide for CAD-CAM:
Gcode references:
Gcode's are somewhat universal in definition but various legitimate flavors exist depending on what software is injesting them and what machine they are controlling.
This post focuses on Gcoding that is compatible with the K40-S + LW configuration
What follows does not attempt to recreate the definitions in the links above, rather to document the differences. Refer to the references for complete treatments other than the changes outlined below.
Gcode Simulators/Editors;
For learning and developing Gcode these tools are useful:
Although Gcode is a standard for talking to CNC devices the implementation and interpretation of these codes can vary. This is clearly a case of "your results may vary". The best approach is to create a series of tests that emulate the Gcodes you plan to employ and see how they react.
For example and in the case of a laser cutter, the way the laser cuts is different than a mill therefore to control power a parameter for setting the lasers PWM is needed. In the K40-S that parameter is the "S" value.
You must understand the adaptations your machines interface software (LaserWeb) and firmware (Smoothieware) have made to properly control the target machine.
Gcode hand coding:
I have found these conventions to be useful in G-coding in a way that is universally interpreted correctly. This is especially true in LaserWeb.
 - Put each Gcode and its parameters on a separate line
 - Use capital letters for parameters i.e. X,Y,Z,F
 - Use at least one decimal place on numbers I.E. G1 X1.0
 - Absolute positioning (G90) is less confusing than incremental positioning (G91) and less likely to run gantries into the stops.
Special K40-S Gcode formats
Adapted Gcodes for K40-S follow.
The G01 command
G01
 - X- x position
 - Y- Y position
Currently Unsupported LaserWeb Gcodes
Mcodes (Machine options)
Coordinate systems:
Coordinate systems in CNC can be very confusing but in 2D laser systems they are the simplest. In fact when using software like LaserWeb the complexity of the coordinate systems is transparent to the user.
However there are advanced times when you want to understand the machines movements within the context of the coordinate systems so here is some information.
WCO: Work coordinate offset.
When using your K40 the WCO and MCO aren't important as LW hides this complexity and describes positions within one system.
There are six user-definable work coordinate systems (WCS) available that are selected with the G54-G59 commands (Note that if using Carbide Motion it seems to store position information in G54 and will over-write any user setting). These are modal, meaning that once you select a WCS all following commands will reference that coordinate system until you select a different one. They are also persistent, meaning that they will be stored between resets and power cycles.
MCO: Machine coordinate offset.
Machine coordinate system. The systems initial home at power on.

Diver Breathing Gas Re-heater for Closed Circuit Underwater Breathing Apparatus
Phone: _PHONE_
Phone: _PHONE_
The objective of this proposal is to develop a robust, lightweight and compact device for re-heating and maintaining the temperature of a divers inspired breathing gas when diving on a closed circuit underwater breathing apparatus for the duration of the dive. As a solution, Simuleer proposes to develop the Hybrid Energy Abiotic Thermoelectric (HEAT) system based on a high-power hybrid (i.e. passive and active) power system in order to meet the high power (~35-200 Watts) needs of this application scenario. The HEAT innovations enable a compact (for maximum maneuverability), powerful (to achieve peak power needs of 200 Watts), long-lasting (to provide heating for a >8 hour long dive), system without any breathing obstruction (for maximum comfort).In Phase I Simuleer will perform a feasibility study to determine potential solutions that meet the required specifications, and document the results.Based on results of the feasibility study, analysis and simulations of the system components will be performed to ensure that operational characteristics are in line with specification requirements.In Phase II, Simuleer will develop, install, and demonstrate a prototype HEAT system based on the Phase I feasibility study of a diver breathing gas re-heater for a closed circuit underwater breathing apparatus.

KYOTO, Japan — It makes no difference if your surgeon is a man or a woman, according to new research out of Japan. Scientists report male and female surgeons had the same rates of death or surgical complications, despite female surgeons often taking on more challenging procedures and high-risk patients.
Study authors are advocating for more opportunities for female surgeons. They note that on a global scale, women are still a minority in the surgical field. On a more positive note, the number of female physicians has increased in recent years.
More specifically, female general surgeons accounted for just 28 percent of Canadian surgeons in 2019, only 22 percent of U.S. surgeons in 2019, and 33 percent of U.K. surgeons in 2017. Meanwhile, women only account for 22 percent of physicians in Japan, and a meager 5.9 percent of surgeons. Still, prior studies in the United States and Canada reveal that the proficiency of female physicians and surgeons is actually equal to or greater than that of their male peers.
Women are more likely to take on high-risk patients
To research this topic further, researchers made use of the Japanese National Clinical Database (NCD), which features data pertaining to 95 percent of all surgeries performed in Japan. Study authors compared that data to surgical outcomes among female and male surgeons between 2013 and 2017. Additionally, they examined the relation between postoperative mortality (within 90 days of surgery) and surgical complication rates (within 30 days of surgery), and the surgeon's licensing terms.
The team placed particular emphasis on three common procedures for stomach and rectal cancer: distal gastrectomy, total gastrectomy, and low anterior resection. They chose those three because enough female surgeons have performed these surgeries to facilitate an analysis while keeping the surgeons anonymous. The complete analysis featured 149,193 distal gastrectomy surgeries, 63,417 gastrectomy surgeries, and 81,593 low anterior resection procedures.
Study authors found that female surgeons performed only five percent of these procedures and were much less likely than their male counterparts to work in high-volume medical facilities. Yet, hospitals were more likely to assign female surgeons to high-risk patients, defined as patients who were either malnourished, on long-term steroids, or with more severe disease.
Despite all that, there were no overall differences in the rates of death or surgical complications between male and female surgeons. Study authors were sure to account for other patient-related factors as well.
Female surgeons face many obstacles
Female surgeons, on average, had fewer post-registration years, and performed fewer minimally invasive (keyhole) surgeries than male surgeons. The research team speculates this could be the result of fewer training opportunities linked to preferential treatment toward male trainees, or the competing demands of women's traditional societal roles, such as raising a family.
Ultimately, the team notes that this project was observational in nature, meaning they can't make a firm conclusion about cause and effect. Study authors admit that at this time, they cannot rule out the possibility that their results are the result of other factors they did not measure. This project also failed to consider all the details on surgeons' work and personal life conditions, and it may not apply to other types of surgeries or procedures performed by surgeons with other specialties.
However, study authors still argue their findings hold scientific merit and warrant further research. This project featured the use of a highly accurate clinical database in terms of patients' preoperative condition and surgical outcomes and accounted for important patient related factors tied to the individual procedures selected.
"Many aspects can impair the successful development of female surgeons," researchers write in a media release. "Nevertheless, in this analysis, no significant difference existed in the mortality or complication rates of surgeries done by female and male surgeons, suggesting that they are equally successful in developing their surgical skills."
"More appropriate and effective surgical training for female surgeons could further improve surgical outcomes," they add.
Does the medical community need 'rapid change'?
Cherry Koh, a colorectal surgeon based in Australia, adds that these findings don't only apply to Japan; female surgeons all over the world have had similar experiences. She believes that changes across virtually all facets of society are necessary to better support women in the workforce. Leadership at all levels — government ministers, professional surgical societies, hospital managers, and departmental leads — also need to commit to change.
"Only through broad engagement can national regulations (such as targets or quotas supporting gender equity in recruitment, training, and retention) be combined with local measures (such as codes of conduct, safer workplace practices, and mentoring opportunities)," Koh concludes. "Rapid change is needed, in the interest of both clinicians and patients."
The study is published in The BMJ.

Design and Simulation
The design of analogue circuits starts with a schematic, which is used for various time and frequency domain simulations and optimizations. Passive layout structures such as transmission lines and inductors have to be simulated using 2.5D and 3D electro-magnetic simulations. For very high frequencies even the small interconnects have to be simulated. An optimized schematic is used for the layout design, which transfers the schematic to the production technology. Once more these layouts have to be simulated and in turn may have to be optimized leading – an iterative process of schematic and layout changes till the final design.
Chip performance can be optimized for various parameters such as frequency range, output power, noise level, chip size, power consumption, temperature range. These parameters cannot be simultaneously optimized. Our goal is to find an optimal trade-off for the given application with you.
Real World Tests
Simulated and measured chip performance usually shows some difference and a redesign of the chip may be necessary. Designer experience is the crucial factor here – not just for proper design and simulation but also for foreseeing the difference between the simulated and expected measured performance. Our design team can provide this knowledge avoiding unnecessary iterations.
Typical Parameters for MMIC Optimization:
- Frequency range
- Output power
- Noise level
- Chip size
- Power consumption
- Temperature range

Kalani discusses how basic life rhythms relate to several aspects of health and how those rhythms align with and relate to musical experiences. You'll learn about the different rhythms of the body and get some ideas as to how to structure musical experiences to support and facilitate positive physical and emotional changes that lead to greater health for groups. You'll also learn how to use 'the rhythms of life' to support your own health goals.
Rhythms are part of every-day living and many of the body's natural rhythms can be used within musical experiences to facilitate positive health changes. This is accomplished through designing and facilitating structured experiences that align with and modulate the bodies natural rhythms in ways that are intentional and desirable. Two primary areas of focus include the rhythms of walking and the rhythms of breathing. Both of these areas relate to ï¿½our general physical health and can be developed to affect emotional and spiritual health.

When you look at it from broader perspective it is a from of 3d printer which prints with carbon fiber, it just needs to be upgraded and developed to be able to print non-rotating shapes with full x/y/z movement or at least to reinforce ABS/PLA parts with carbon fiber applied on their surface.
There were similar solutions on the beginning of DIY 3d printing machines development like this 3d printer which printed silicone on rotating tube:
There were successful applications of epoxy surface glued Kevlar and carbon fibers on regular ABS/PLA 3d printed parts which gave them amazing strength:
For next level in carbon printing we need to bring those concepts in a single machine.
Hopefully there will be someone to develop this idea further.

text: Background: The majority of patients with pancreatic cancer present with advanced disease. Systemic chemotherapy has limited impact on overall survival (OS) so that eligible patients should be selected carefully. The aim of this study was to analyze prognostic factors for survival in Turkish advanced pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving gemcitabine (Gem) alone or gemcitabine plus cisplatin (GemCis). Methods: This retrospective evaluation was performed for patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and who received gemcitabine between December 2005 and August 2011. Twenty-seven potential prognostic variables were chosen for univariate and multivariate analyses to identify prognostic factors associated with survival. Results: Among the 27 variables in univariate analysis, three were identified to have prognostic significance: sex (p = 0.04), peritoneal dissemination (p = 0.02) and serum creatinine level (p = 0.05). Multivariate analysis by Cox proportional hazard model showed only peritoneal dissemination to be an independent prognostic factor for survival. Conclusion: In conclusion, peritoneal metastasis was identified as an important prognostic factor in metastatic pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving Gem or GemCis. The findings should facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.

Anton Probst brutally slaughtered eight people on a family farm in 1866
Books Murder
01112018_Anton_Probst./.
Anton Probst, above, used a hammer and axe to kill Christopher Deering, his wife and four children, as well as a family friend and employee, in 1866, in what is now South Philadelphia. A new book looks for links between the murderer and Frankenstein.
In "The Face of a Monster: America's Frankenstein," Delaware author Patricia Earnest Suter revisits the gruesome killings of eight people at the hands of Anton Probst in 1866.
A German immigrant, Probst came to the United States in 1863 and became a "bounty jumper" during the Civil War, joining up with Union regiments and collecting his check before deserting and doing the same with another troop.
After squandering away his money, he took a job for the Deering family as a farm hand in rural Philadelphia. To enrich himself, he killed Christopher Deering, his wife, four of their children, a family friend and another employee, slicing their throats and crushing their skulls before ransacking the house and hiding the bodies in hay.
Probst had the unmoved demeanor of a cold-hearted killer, but not the intelligence of one. A New York Times report about his execution details how detectives found him not far away in what's now considered Old City, drinking and selling away the family's possessions.
His trial was quick, and after initially only admitting to one killing, he opted to confess entirely when he was found guilty by a jury. Probst detailed how he slaughtered each person with a hammer and axe, and was reportedly "quiet, undemonstrative, cool and unembarrassed" at his hanging.

The cover for 'The Face of a Monster: America's Frankenstein,' an upcoming book that revisits Anton Probst's brutal Philadelphia murders.
In her coming examination of Probst's murders, Suter hopes to have created an "imaginative blend of fiction and reality" by showing the parallels between Probst's ruthless crime and the monster in Mary Shelley's 1818 novel, "Frankenstein," just in time for the legendary book's 200th anniversary.
"(Shelley's) monster personified abandonment and loneliness, feelings Shelley shared. In despair, the creature resorts to violence and the novel darkens into tragedy," a preview for the book reads.
"Fifty years later, Anton Probst adopted characteristics of Shelley's monstrous creation."
For "The Face of a Monster," Suter, who's written previously about notorious true crime in the area, sourced "Frankenstein" and accounts from Shelley's inner circle as well as modern accounts of Probst from journalists and lawyers.
"This is a story of life imitating art," the preview reads. "Over the course of researching and writing 'The Face of a Monster: America's Frankenstein' Suter discovered that monsters exist and that her childhood belief was right: they almost always adopt human form."
The book will be available in hardback for $14.99 and via e-book for $9.99 on March 11.


text: Originating from natural language processing, the new paradigm of prompting has recently swept through the computer vision community, bringing disruptive changes to various computer vision applications, such as image recognition and image generation. In comparison to the traditional fixed-once-learned architecture, like a linear classifier trained to recognize a specific set of categories, prompting offers greater flexibility and more opportunities for novel applications. It allows the model to perform new tasks, such as recognizing new categories, by tuning textual instructions or modifying a small number of parameters in the model's input space while keeping the majority of the pre-trained parameters untouched. This paradigm significantly pushes conversational human-AI interaction to unprecedented levels. Within a short period of time, the effectiveness of prompting has been demonstrated in a wide range of problem domains, including image classification, object detection, image generation and editing, video analytics, and robot control. In this tutorial, our aim is to provide a comprehensive background on prompting by building connections between research in computer vision and natural language processing. We will also review the latest advances in using prompting to tackle computer vision problems.

What are Hospital Ice Chips?
Table of Contents
For oral hydration, hospitals use small pieces of Ice chips to soothe a sore throat or to cool the mouth and throat. Methods to make hospital ice chips are crushing ice cubes or breaking up the block of ice. Ice chips are typically made from purified water and are safe to consume. When patients cannot drink more significant amounts of liquid because of illness or medical treatment, they are commonly used in hospitals and other healthcare settings to help patients keep hydrated and comfortable. Some people also use ice chips at home to help with dehydration, sore throat, or other conditions that affect the mouth and throat.
Benefits Of Ice Chips
- Hydration: Ice chips can help to hydrate the body because is solid form of water. People who have trouble swallowing or might feel sick and struggle to drink more significant amounts of water will find this to be especially helpful.
- Cooling effect: Ice chips can provide a cooling effect on the body, which can help reduce fever or overheating.
- Sore throat relief: Ice chips can help numb the throat and temporarily relieve soreness or irritation.
- Oral hygiene: Ice chips can help to clean the mouth and teeth, as the cold temperature helps to make it bacteria free and freshen your breath.
- Digestive aid: Ice chips can help digestion, stimulate the small intestine, and reduce bloating or discomfort.
- Pain relief: To numb, use ice chips and reduce pain in some body regions, such as following a dental procedure or during a sports injury.
- Weight loss: Some people use ice chips to curb hunger cravings and assist with weight loss efforts.
- Energy boost: Ice chips can provide a quick burst of energy, as the body uses energy to heat the ice and bring it to body temperature.
Why Hospitals Give Ice Chips
Hospitals give ice chips for several reasons:
- Hydration: Ice chips can help keep a patient hydrated, especially if they cannot drink more significant amounts of fluids due to illness or surgery.
- Comfort: Ice chips can comfort patients who may have a dry mouth or throat due to medications or treatments.
- Oral care: After surgery, a patient might not be able to brush their teeth or wash their mouth with water. Ice chips can help to clean the mouth and teeth.
- Cooling: Ice chips can help to cool down a patient's body temperature in the hospital.
- Swelling: Ice chips can help to reduce swelling in the mouth, throat, or other areas of the body.
Ice chips are a simple but effective way to help care for patients in a hospital setting.
Why to Have Ice Chips only Before Surgery?
You can only have ice chips before surgery because they are easy to digest and do not need chewing or digestion. It is crucial because, during surgery, the body's digestive system is essentially shut down, so anything eaten before surgery will sit in the stomach and intestines without being properly processed. It can lead to nausea, vomiting, and other digestive issues. On the other hand, ice chips can be quickly and easily absorbed by the body and do not pose any potential digestive problems. Additionally, ice chips can help to keep you hydrated and can provide some relief for dry mouth or throat.
What Kind Of Ice Maker Do Hospitals Use?
Hospitals typically use commercial ice makers, which are larger and more powerful than residential ice makers. These ice makers can produce large quantities of ice, making them ideal for busy hospitals where ice is use for various purposes such as patient care, food and beverage service, and laboratory research. Some hospitals may also use ice makers specifically designed for medical use, equipped with features such as built-in water filtration systems to ensure the ice is clean and safe to consume.
In conclusion, hospital staff gives their patients ice chips since it simply keeps them hydrated before and following surgery. It makes sense to provide commercial ice rather than manually crushed ice to your patients, visitors, or staff members so they can enjoy their fizzy water or drinks while staying chilly or cool on a warm day.

7 Ways to Deal With Arrogant People
7 Ways to Deal With Arrogant People
Image by 愚木混株 Cdd20 from Pixabay
Arrogant people do think that they are and will always be right. They get stuck to false assumptions and ignore hearing what other people say. They will use superior language, bully people, and become bigoted of people, or just act total rudely.
They consider themselves excellent. How you react to them becomes necessary when peace of mind is considered.
Your reply to an arrogant person is also a representation of your uprightness as a person who holds up himself.
Sometimes it becomes difficult to be sound these people because they can begin to pick away your self-confidence.
We run out of words and forget how to react to the situation.
How to save yourself from the verbal attacks of an arrogant person?
If you cross paths with these people who are self-stuck, do follow these suggestions.
So, How to deal with arrogant people? We have added different strategies to the tricky points.
Here are 7 Ways to deal with arrogant people
1. Have high self-confidence:
One of the best ways to face an arrogant person is by displaying your high confidence. Always enter into conflicts with arrogant people only when you are strong and have a depth of knowledge about a matter.
Only then you'll know where are they going wrong. It is important to point them out. It will help you get less victimized by them. You will notice how their behavior changes when that can't relate to you. Instead, they would start saying bad things that are unjustifiable. But have faith in yourself. Confusing them in their own words is your bigger trick.
2. Remember they are insecure:
Try finding sympathy in yourself if you can. Arrogant people bullies and harasses people to take control of them. It's just a reflection of their fear of being controlled. They would never admit their wrongs and stuck to pretenses. Thus they would never take account of your advice or suggestions, no matter how hard you make him try to believe. As being self-centered and the inability of open-minded, their life experiences are less. It becomes too hard to sympathize with someone of this quality.
Do not put them down. Just let them enjoy the fruits of their insecurities because they are never able to see their shortcomings.
3. Don't let it get to you:
Once you allow them to rule or control you, they won't leave a dot to not put you down. They have a very low mentality of finding happiness in other's troubles. Much like a narcissistic nature. This is much easier said than done. Just imagine, what if the person isn't trying to be rude towards you and just try hard to figure out the bigger view. There could be other reasons for a person's conduct. Try spotting them out and blur out these scornful criticisms.
Just laugh it out. Do not stress over it.
4. Be empathetic, but don't try to fix the person:
One's demand for superiority is profoundly grounded and ranges from lower appreciation to a deep craving for approval to a lack of compassion for those who seem less successful. Only the domineering person can deal with such a problem and with a continued push. On the other side, it brings peace to your heart and possibly to the circumstances if you have compassion for the grief of others.
5. Be mindful:
Whatever we decide to do, we should do them carefully and with much love as practicable. They make others lose their temper and become the worst version of themselves. You need to be very careful while handling these people. They are rotten from inside and would spread that rot within us too. We should be careful while dealing with them. Try to perform the sport of your life rather than trying to fit into someone else's. Be faithful to yourself always.
6. Try changing the topic of the conversation:
If nothing works wonders, try to change the topic of conversation. Arrogant people love to dominate over one particular topic, and if the decision to change the topic has been taken, they will bounce back. They will become defenseless. If you try switching to something that is neutral or something you know more about, they will try to find a way to jump back to the previous topic. They play dominating roles in our society. When people like us ask them anything out of the syllabus, they wouldn't answer them or might speak badly about you. After all, this is what they know.
You should try to be calm in such situations.
7. Avoid interaction at all possible means:
If you are in close proximity with such a person, your days can be tough. Do whatever it takes, to lessen the effect of this soul. Do not get close to them or park cars near their cars, I mean never!
When you meet them just smile and exchange glances. You might say "good morning", "good day" just in case, or occasional "hmm".
Do not let them know that you're avoiding them and don't want to interfere in any of their matters.
Find more ways to walk out and ignore these people. To maintain your own understanding, it's best to keep a proper distance between you.
Just dodge them by any means!

The integration of microgas turbines (MGT) and absorption chillers is an emerging technology that uses a wide range of fuels to produce electricity, cooling and heating simultaneously for small scale distributed generation in grid connected or isolated locations. This paper studies the performance of MGTs of different power capacities directly coupled to double-effect water–LiBr absorption chillers. In these systems the MGT exhaust gas is the heating medium to drive the chiller. Also post-combustion natural gas is used to increase the cooling capacity of the system. The paper analyses the effect of the post-combustion degree on the integrated system performance of four MGT power sizes. Two cases are considered. In the first, fresh air is added together with the post-combustion natural gas and in the second it is not added. In the latter case the oxygen necessary for the combustion reaction is extracted from the MGT exhaust gas stream. For the sake of comparison a study is also made of the performance of a more conventional system consisting of an MGT and a hot water heat exchanger to drive an absorption chiller. The main advantages of the new technology over this conventional system are that the COP of the chillers is higher because they are driven by higher temperatures, the production of electricity and chilled water is decoupled and there is a wider range of chilled water production capacity.
The new distributed generation equipment coming onto commercial and industrial markets provides waste heat that can be applied to absorption cooling. This significantly increases overall system efficiencies. On the other hand, expanding power demands, increasingly restrictive environmental regulations and the deregulation of the electricity market are providing an opportunity for developing these new on-site distributed generation technologies such as microgas turbines (MGT). MGT technology can be integrated in distributed power generation systems to produce electricity, heating and cooling simultaneously for air conditioning and industrial applications although such uses as vehicle propulsion are also currently under development. The main advantages that they have over other competing technologies are the fuel flexibility, low emissions, quiet operation and low maintenance and. The electrical efficiency of the current regenerative MGTs, which are also characterised also by low pressure ratios and modest turbine inlet temperatures, is in the range of 25–30% depending on the MGT size. Thus if the overall system efficiency is to be competitive the waste heat available in the MGT exhaust gas must be effectively recovered. In warm climates such as the Mediterranean where there can be long hot periods, so-called trigeneration systems (power, hot and chilled water) are a better alternative than the simple cogeneration system for producing only power and heat. Absorption refrigeration systems can be used in combination with MGT to recover MGT waste heat so that chilled water can be produced and the electric load demanded by the more conventional compression refrigeration systems reduced or eliminated. Nowadays the only commercially mature technology for cooling using absorption chillers for small power applications in combination with MGT is the one using an intermediate gas/water heat exchanger that produces hot water to drive the absorption system. Because of the low temperatures, only single-effect absorption chillers can be used. So the existing MGT/absorption systems are too limited: their COPs are too low, the range of chilling capacities are not wide enough, and electricity and cooling capacity depend completely on each other, etc. For these reasons it was decided to analyse the possibility of using the exhaust gas in direct fired absorption machines with the option of natural gas post-combustion. Direct-fired chillers are more efficient and better positioned in the refrigeration market than their hot water driven counterparts. Some research projects are being carried out into direct MGT exhaust gas fired absorption systems although not all of them use cofiring. The most well known are the CEEE project at the University of Maryland, Southern California Gas Co., Takuma/Capstone and Ingersoll–Rand/Hussman all in the USA, the University of Pisa project in Italy and the Icogen S.A. development in Spain. Some new small ammonia/water generator–absorber heat exchange (GAX) chillers are promising because they can be driven directly by exhaust gas and do not require a cooling tower. These GAX systems are entering the market now (2004). The objective of this paper is to study the integration of MGTs and double-effect direct-fired absorption systems. The exhaust gases from the MGT are directed to the absorption chiller with the option of additional natural gas post-combustion. Two cases are considered. In the first, fresh air is added together with the post-combustion natural gas. In the second, fresh air is not added and the oxygen necessary for the combustion reaction is extracted from the MGT exhaust gas stream. A comparison is made with a similar system that uses a hot-water driven absorption system. Before the modelling characteristics and the results are presented, the current technology in MGT and absorption cooling suitable for MGT/absorption refrigeration coupling will be briefly reviewed. Also the special features of the various MGT/absorption refrigeration integrated systems will be presented.

The main advantages of a directly driven absorption chiller with a post-combustion system over the more conventional single-effect hot-water driven system are a higher COP, a decoupling between electricity and chilled water production and a wider range of chilled water production capacity. Two directly fired cases have been studied: in one case extra fresh air was added for post-combustion and in the other it was not. With additional fresh air, the cooling capacity of a directly fired double-effect chiller integrated in an MGT with an electric power capacity between 30 and 100 kWe increases from 500 to more than 1600 kW depending on the MGT size and the degree of post-combustion. In the MGT/absorption chiller system with post-combustion and fresh air there is an optimum amount of post-combustion represented by a PCF ratio of about 0.25 that produces the optimum global operation point of the system. This means that at this ratio value, the operational costs will be lowest. This point of maximum efficiency exactly matches the maximum temperature of the gases entering the chiller. As the amount of post-combustion natural gas increases so does the cooling capacity but the fresh air required for cofiring also increases and dilutes the heat provided by the gases coming from the MGT. For this reason the cooling power decreases after a certain optimum value of post-combustion is exceeded. When no additional fresh air is added for the post-combustion, the MGT exhaust gas is directly used as combustion air. In this case, the amount of post-combustion natural gas is limited by the maximum temperature that the post-combustion chamber can withstand, not by the oxygen content in the MGT exhaust gas. The maximum cooling capacity in this case is lower than when additional fresh air is used. Below this maximum point, the cooling capacities with and without additional air are not very different but higher when fresh air is added.


Wastewater treatment plants (WWTPs) are a significant energy consumer, yet there are several opportunities of implementing on-site power generation systems. Within the treatment process, the high flow rate of effluent is produced and discharged to a nearby water body by gravity. Thus, hydro turbines can be utilized to generate power in such application due to a difference in elevation and high flow rate. This paper presents a case study of introducing a hydro turbine in wastewater treatment plant in Wisconsin and evaluating the power output in addition to determining the energy savings. The wastewater treatment plant considered in this study has an effluent flow rate of 190 MGD (million gallons per day) and elevation difference of 3 meters (10 feet) between the final stage of treatment and the discharge point. Based on the aforementioned parameters; hubless rim-drive Kaplan type hydro turbine (RDT) is the optimal choice to be used in such application. The RDT is designed and optimized by using in-house code. A computational fluid dynamics (CFD) software is applied to evaluate the performance of the proposed model, and the system is simulated through HOMER software to validate the results generated by the CFD. The expected savings is estimated to be 1,564 MWh/year.
