I am seeking to understand that "average" file size for a folder on my computer. I have calculated the true average of files (total size / no. of files), however I would, ultimately, love to group together files into file-size categories as follows;
Files < 1kb: 23 files.
Files < 100kb: 276 files.
Files < 1mb: 786 files.
Is this possible using a batch script?

Yes this is possible.
You will need to write some code that follows along an algorithm of your choice, using variables to store values.
The algorithm could look perform actions like this:
 - define File-Size-Range-Groups ( < 1kb, < 100 kb, etc )
 - Sum the number of files in each File-Size-Range-Group
 - Sum the individual file sizes for a File-Size-Range-Group total
 - Output the sum value of files in a File-Size-Range-Group
 - Output the average (total file size sum for File-Size-Range-Group / number of files in File-Size-Range-Group)

Hormones in Metamorphosis of Amphibia
In amphibians, the changes that take place during metamorphosis are brought about by hormonal secretions of the thyroid gland. The first sign of this was obtained in 1912 when Gudematsch reported that frog tadpoles while fed dried and powdered sheep thyroid underwent precocious or early metamorphosis. Identical results however were not observed when tadpoles were fed along with preparation of other glands. These experiments made it feasible to postulate that thyroid hormones bring about metamorphosis.
In 1918 B.M. Allen observed that elimination of thyroid rudiment from early frog tadpoles, prevented them from going through metamorphosis, and caused them to become giant tadpoles instead. Conversely, if they were fed with thyroid or immersed in water containing soluble extracts from thyroid glands they then proceeded immediately to metamorphosis. Identical experiments in urodele amphibians, in particular in axolotl, Ambystoma mexicanum, also indicated the significance of the thyroid gland in urodele metamorphosis.

Properties of sediment phosphorus in seven wetlands of the Swan Coastal Plain, South-Western Australia
*Subscription may be required
Seven wetlands from two dune systems on the Swan Coastal Plain, Western Australia were studied for sediment properties associated with phosphorus retention and potential remobilization. Sediments from the Spearwood Dunes had higher contents of silt, clay, and organic material. Sediment total phosphorus was positively correlated with water content, organic matter and silt content but inversely related to the amount of coarse materials. Part of the organic matter was refractory humic substances, and the molecular weight of humic acids ranged from less than 10,000 to over 600,000. Significant portions of sediment total P (5–73%) were bound to humic substances. The fraction of "loosely-bound phosphorus" (NH4Cl-P) accounted for less than 10% of total-P. NaOH-extractable P was high; some humic substances were extracted with NaOH. Correlations between phosphorus forms and other components suggest an affinity between 'fine particles' of similar hydrologic density during sediment transport and reworking, and this involves most humic-P in these wetlands.

The quantity of available water resources has been recognized as the key limiting factor for development of most of the arid regions. This paper focuses on the simulation–optimization for conjunctive use of surface water and groundwater on a large scale. In this study, Hetao Irrigation District in China, one of the largest irrigation districts in the Yellow River basin, is selected as a representative study area. The conjunctive management model of water resources is developed by means of dynamically coupling a large-scale hydrological model with an optimal allocation model. A groundwater level is adopted in the coupled model as the constraint condition and the optimal conjunctive utilization quantity of surface water and groundwater is set as the objective function. Finally, the coupled model is applied to calculate the optimal water supply quantity of surface water and groundwater and sustainable utilization scheme of water resources for 2020 and 2030 in Hetao Irrigation District. The modeling results demonstrate the conjunctive management model of water resources is an effective tool for appraising water resources in large-scale arid regions.

Gas Turbine Alternator RTDs Meaning and Explanation
Hello everyone,
We are in operation of 19.6 MW GE make gas turbine (Mark Vie control system) with Brush make alternators. There are nine RTDs installed for alternator i.e. :
1. Stator coupling end : 3 nos, (DTGSF1, DTGSF2, DTGSF3)
2. Stator collector end : 3 nos : (DTGSA4, DTGSA5, DTGSA6)
3. Cold gas TE : 1 no ( DTGGC10)
4. Hot air TE & CE: 2 nos (DTGGH18. DTGGH19)
Can anyone explain what are meaning of the tags, its functions and its importance?
Thanks and regards
>1. Stator coupling end : 3 nos, (DTGSF1, DTGSF2, DTGSF3)
DTGSF1 Detector, Temperature-Generator Stator Forward #1
DTGSF1 Detector, Temperature-Generator Stator Forward #2
DTGSF1 Detector, Temperature-Generator Stator Forward #3
There are three RTDs, embedded in the generator stator at the "forward" end of the generator (also referred to as the turbine end, or the drive end, or the driven end), usually one RTD in each phase (of the 3-phase generator)
>2. Stator collector end : 3 nos : (DTGSA4, DTGSA5, DTGSA6)
Detector, Temperature-Generator Stator Aft #4
Detector, Temperature-Generator Stator Aft #5
Detector, Temperature-Generator Stator Aft #6
There are also usually three RTDs, embedded in the generator stator at the "aft" end of the generator (also referred to as the collector end, the non-drive end, the non-driven end), usually one RTD in each phase (of the 3-phase generator); I have always presumed DTGSA4 is measuring the temperature of the same phase as DTGSF1, and DTGSA5 is measuring the same temperature as DTGSF2, and so on
>3. Cold gas TE : 1 no ( DTGGC10)
DTGGC10 Detector, Temperature-Generator Gas Cold #10
This RTD measures the temperature of the cold "gas" (air in an air-cooled generator; hydrogen in a hydrogen-cooled generator--the cooling "gas")
>4. Hot air TE & CE: 2 nos (DTGGH18. DTGGH19)
DTGGH18 Detector, Temperature-Generator Gas Hot #18
DTGGH19 Detector, Temperature-Generator Gas Hot #19
There is usually an RTD at each "exit" of the air cooling the generator, one at the turbine end (the "forward" end) and one at the collector end (the "aft" end)
Should a high temperature develop in the generator stator (turbine end or collector end), the embedded RTDs could help in detecting the high temperature. Again, as was mentioned in another thread--operators should always be "trending" readings like these, because if they rise, and the rate of rise, can be an indication of a problem--possibly a serious problem if the rate of temperature rise is very quick.
By monitoring the temperature of the air entering and leaving the generator one can also gauge the effectiveness of the cooling of the generator. Again--trending these temperatures is key to spotting a problem BEFORE it becomes a serious problem.
Hope this helps!
Hello CSA...
Yes this will help. recently the RTD DTGSA-4 was increasing gradually till 96 deg C (normal 70-74 deg C) and operator raised alarm. While troubleshooting b instrument engineer, the GT got somehow tripped. Later we came to know its trip setting is 120 deg C.
Now I have a query.... will it really require to set the particular temp at collector end to be set at 120 Deg C. I think it is not.
But anyway thank you CSA sir for the explanation and help
Would it surprise you to know that most generators supplied with a unit packaged by GE don't have trips configured for the generator RTDs? Alarms, yes; but trips, no.
GE's philosophy as a packager is that an alarm should alert a conscious operator to a problem--which might be or become a serious problem--and the operator can raise the issue with the operations supervisor or other plant personnel to decide what corrective action to take.
This is a good philosophy--because when the turbine control system is configured to alarm AND trip for just about every possible condition then the unit becomes unreliable. In the case you are describing if only one stator RTD is indicating a problem the plant personnel should be able to decide how to handle the situation. In your case, it seems the I&C technician was troubleshooting the issue without understanding how the Mark VIe handles RTDs and what can happen when an RTD is disconnected or the wiring is otherwise "disturbed"--and probably was also unaware that a single out-of-range RTD signal (high in this case) would also result in a turbine trip (if the scenario you described is actually what happened--a LOT of times trips are incorrectly attributed to something OTHER than what really tripped the turbine by people who should know better, but don't--the Trip History and the Alarm Display have the required information to be able to say precisely what tripped the turbine!). And, so, if what you say happened actually happened, this is another case of making the unit unreliable by trying to make it trip for any and all conditions and taking the ability of operators and their supervisors to make appropriate decisions.
Now, if the unit was not configured/programmed to trip on a single high stator temperature and the tech caused an out-of-range signal which would have resulted in a trip had it been configured/programmed to trip on a high-high value then all that would have happened is that the signal would have been out of range and the unit would have continued to run (which is probably what the tech thought would happen because it appears he didn't check to see if the unit would trip on a high value--which should have been done).
So, trying to use the automated turbine control system to protect the unit in just about any or every case can actually have undesired results. And, guess what gets the blame? The Mark* turbine control system! Because it tripped the turbine! And, someone thinks--now--the turbine should not trip on a single high-high generator stator temperature (real or caused by an instrument tech). BUT, when the unit was built and ordered someone in the organization that was purchasing the unit decided the unit SHOULD trip on high-high generator stator temperatures, and so it was configured/programmed that way. And that person is probably long gone and no longer associated with the unit, and now someone (you, included) doesn't believe the unit should trip on a single high-high generator stator temperature reading.
Can you see what the issue here is? It's trying to substitute machine intelligence (that of the Mark* turbine control) for operator and operator supervisor intelligence. And, more and more sites are thinking this way, and this is leading to more and more turbine trips and blame being incorrectly attributed to the Mark*. Because owners and managers don't want to pay operators and technicians to be properly trained and want to let the hero turbine control system make all the decisions about whether or not to trip the turbine to protect it from inexperienced operators and technicians.
Yes; it happens everywhere around the world. Not so much in Europe, but pretty much just about everywhere else. Cut training budgets; pay operators and technicians less; and let the hero turbine control system make all of these decisions instead of trained, experienced operators, technicians and their supervisors. (Most operations supervisors get promoted to that position from a job as an operator. And, if they didn't get much, if any, training as an operator how does that make them a good supervisor? Learning by mistake is not the best way to learn how to run a turbine-generator or a power plant.)
As for the trip value of a reading--120 deg C is about 250 deg F. And, that's a fairly high temperature for a normal, air-cooled generator being operated properly (with a good supply of clean, dry cooling air, an unobstructed air way, a clean generator stator and clean generator cooling fan blades).
Here's the deal: It's not uncommon for embedded generator stator RTDs to fail over time. And it's made worse when generators are operated at high stator temperatures for long periods of time. Now, sometimes, it's just the wiring that gets damaged, but sometimes it's the stator insulation. And, it's very difficult to replace most embedded generator stator RTDs. So, they just get left "open" circuited in most cases. I'm NOT saying that has happened or was happening at your site (you didn't tell us what the results of the tech's checks were, which should have been completed after the turbine tripped and before it was re-started). I'm just saying this is not an uncommon occurrence for many generators around the world.
Finally, RTD wiring is very confusing to most people. VERY confusing. It's actually very simple, but it can appear very complicated. And, the Mark* turbine controls will react differently when one wire is removed as opposed to another (most Mark* RTD inputs require three wires, not just two). (And, that's not documented in


How to Stop Pitting in Aluminum
John Adams
Aluminum pitting is a common type of corrosion that occurs in the presence of water and salt dissolved in the water. You can prevent pitting in your aluminum surface by cleaning, treating and sealing the aluminum surface.
An aluminum boat is particularly susceptible to pitting.
 1. Dry the surface to be protected and sand it. Start sanding with the 400-grit sandpaper, then follow with the 800-grit sandpaper. Then sand the surface with the fine steel wool.
 2. Apply an aluminum cleaner to the surface using the steel wool. Rub this into the surface until it is thoroughly cleaned. Follow the cleaner's application and drying instructions.
 3. Buff out the entire surface using a clean cotton or wool cloth, or preferably an orbital buffer. Apply aluminum polish to the cloth or orbital buffer, and use the cloth or buffer in circular motions until you have removed all traces of the aluminum cleaner. Follow the polish's application and drying instructions.
 4. Once the surface is dry, apply an aluminum sealer to the surface using a second cloth. Do not use the same cloth used in Step 3. Let the surface dry for the period specified on the aluminum sealer's container and reapply if recommended.
 5. Tip
 If your surface gets scratched or dented, this will break the sealant applied in step 4 and allow moisture and salts to restart the corrosion cycle. To address this, you will need to repeat steps 1 through 4 at and near the damaged surface.
 Perform steps 1 through with little pause in between. You do not want the aluminum to sit exposed for long after the sanding. This will leave the surface susceptible to more corrosion.
 Many of the chemicals mentioned in this are harmful to the skin. Wear protective clothing, especially gloves, and follow all warnings.

Patient context - the "envirome" - can have a significant impact on patient health. While envirome indicators are available through large scale public data sources, they are not provided in a format that can be easily accessed and interpreted at the point of care by healthcare providers with limited time during a patient encounter. We developed a clinical decision support tool to bring envirome indicators to the point of care in a large pediatric hospital system in the Kansas City region. The Envirome Web Service (EWS) securely geocodes patient addresses in real time to link their records with publicly available context data. End-users guided the design of the EWS, which presents summaries of patient context data in the electronic health record (EHR) without disrupting the provider workflow. Through surveys, focus groups, and a formal review by hospital staff, the EWS was deployed into production use, integrating publicly available data on food access with the hospital EHR. Evaluation of EWS usage during the 2020 calendar year shows that 1,034 providers viewed the EWS, with a total of 29,165 sessions. This suggests that the EWS was successfully integrated with the EHR and is highly visible. The results also indicate that 63 (6.1%) of the providers are regular users that opt to maintain the EWS in their custom workflows, logging more than 100 EWS sessions during the year. The vendor agnostic design of the EWS supports interoperability and makes it accessible to health systems with disparate EHR vendors.

Size-dependent vibration of bi-directional functionally graded microbeams with arbitrary boundary conditions
- Additional Document Info
- View All
© 2017 Elsevier Ltd In this paper, the free vibration behaviour of bi-dimensional functionally graded (BDFG) microbeams under arbitrary boundary conditions (BCs) is studied. Based on the frame work of the modified couple stress theory and Hamilton's principle, governing equations of motion are developed for the BDFG microbeams using a quasi-3D theory. The formula then can be reduced to a higher-order beam theory (HOBT) of conventional functionally graded (FG) microbeams with the material properties varying along the thickness direction only. Two types of BDFG microbeams with different patterns of material volume distribution are considered. The material properties used in this study are assumed to vary exponentially along both longitudinal and thickness directions of microbeams. Based on the state-space concept, the governing equations are solved for natural frequencies and vibration mode shapes of microbeams under various BCs. The effects of material distribution, geometric parameters and BCs are also investigated to examine the size-dependent behaviour of BDFG microbeams.

Ghana As a Tourism Country
Ghana As a Tourism Country
Ghana is in many ways a warm tourist destination. The heat of more than 30 degrees does not compare to the warm kindness of the locals.
Ghana in Western Africa is not one of the most traditional tourist destinations, but Ghana has a lot to offer for those interested in wildlife bonga, the tropics and fiery food, among other things. In Ghana, you can also go on a cruise to the world's largest dam lake.
Ghana 2
Versatile Ghana
According to countryaah, the Republic of Ghana is a former British colony in West Africa on the Atlantic coast. The country is home to about 24 million people and is bordered by Togo, Burkina Faso and Côte d'Ivoire. The main exports of Ghana, which became independent in 1957, are gold and cocoa, and tourism plays only a small role in the country's economy.
Ghana is especially known as a cultural and nature tourism destination. Ghana is diverse in its terrain, with deserts and savannas as well as river landscapes and rainforests. Ghana is located in more than one natural park, of which the most significant are Molen and Kakumin national parks.
There are also cultural attractions in Ghana. There are two UNESCO World Heritage Sites in the country: Ghana's castles and fortresses and the Ashanti buildings. Many tourists start exploring Ghana from the country's capital, Accra.
Ghana's climate
Ghana has a tropical warm climate. Daytime temperatures in the country often rise to around 30 degrees and there is little seasonal variation in temperatures.
There are some regional differences in Ghana's climate. There are two rainy seasons on the coast of the country, spring and autumn. The spring rainy season falls in April-June and the autumn rainy season in September-October. The shorter autumn rainy season does not extend to the central parts of the country. During the rainy seasons, it can rain a lot, especially in the interior of the country.
Friendly Ghana
Short for GH by abbreviationfinder, Ghana is a very friendly country and locals often greet tourists on the street and in the shops. It is very rude not to respond to people's happy greetings. For example, in the marketplace of the city of Kumas, which is very diverse in terms of population, where goods and food change hands, happy greetings are heard from the right and the left.
In addition to its friendly atmosphere, Ghana is known for its nature. In the country, for example, there is a large dam lake Volta, which is led by a river of the same name. On the Volta River and the islands of Lake Volta, such as Dod, Dwarf and Kporve, tourists can also visit by cruise ship.
Ghana's Natural Parks offer plenty to see for tourists interested in savannas and rainforests. Ghana is the largest natural park in Mole National Park, but the country also found in numerous other, smaller parks. Many local tour operators and park guides organize nature excursions and sightseeing tours.
Cheap shopping and hot food
Ghana is an affordable country, so shopping is worth it, and especially the food is worth enjoying to the fullest. In Ghana's shops, you can buy, for example, beautifully patterned local fabric and beautiful handicrafts. The best shopping and the biggest shopping can be found in the capital Accra.
Ghana has plenty of dining options, from hotel restaurants and expensive sophistication to small cupboards and food carts across the street. Ghanaian food is quite hot, so you should taste the snacks carefully at first. In Ghana, you should also try a homemade pit drink.
The busiest nightlife in Ghana is Accra, which has sports bars and Irish pubs along the streets and around the hotel. There are also a few trendy nightclubs in the city.
Good to know about Ghana
Ghana is a peaceful country and its administration is stable. Ghana also has a high standard of living in Africa. As a tourist destination, Ghana is relatively safe, but common sense is always good to follow.
Ghana is fluent in English, whose official language status dates back to British colonial times.
Before traveling to Ghana, it is advisable to visit a doctor to discuss the necessary vaccinations. For example, anti-malarial medication and yellow fever vaccine should be treated before traveling to Ghana.
Flights to Ghana
There are no direct flights to Ghana from Finland, but you can fly to the country via a major European city, such as Brussels or Frankfurt.
Ghana has several airports, but the country is usually reached via Kotoka International Airport. Kotoka Airport is located about ten kilometers from Accra.
Flights to Ghana cost around € 800-100.
Hotels and accommodation in Ghana
Ghana has a lot of good-value and mid-range hotels, especially in major population centers like Accra. The city also has luxury accommodation and five-star hotels. Luxury hotels often have a swimming pool and good facilities.
On average, a hotel night in Ghana costs about 60-80 euros and at its cheapest you stay in the country for 10-40 euros. The level of the cheapest accommodation can be really modest.
Getting around in Ghana
Buses are the most convenient and reliable way to get around Ghana. The bus company Vanef-STC provides connections between major cities and other bus companies operating in the country include OSA, Kingdom Transport Services (KTS), City Express and GPRTU.
If you want to travel to smaller destinations and have good nerves, you should hop on a minibus aboard the tro-tron. The tro-trot does not move according to schedules but on demand, so the cars are packed full of passengers before departure. Finding a tro-tron to the right destination can be difficult for a traveler, so it's worth asking locals which route takes you anywhere. Tro-trot are a really affordable ride and the shortest trips cost just a few cents. Tro-trots also run in local urban traffic.
The capital of Accra
The capital of Ghana, Accra, is the largest city in the country with a population of a couple of million people. Accra is located on the shores of the Gulf of Guinea. In the city you can visit, for example, the National Museum of Ghana and Christianborg Castle, originally built by the Swedes.
Mole National Park
Mole National Park is Ghana's largest natural park and it is located in the northwestern part of the country about 670 kilometers from Accra. The park is home to numerous exotic animal species such as elephants and lions. Mole National Park is a popular ekoturismikohde Ghana.
Kakumi National Park
Mole National Park considerably less Kakum is located approximately 170 kilometers from Accra. The park is known for its long suspension bridge, from the heights of which you can observe the animals of the rainforest. The park is home to many species of animals such as monkeys and parrots.
Ghana Fortress
Ghana's colonial forts were inscribed on the UNESCO World Heritage List in 1979. There are several forts around Ghana. The oldest of the fortresses is the 15th century Elmina Castle, located in Elmina. The most famous of the castles are the castles of Cape Coast and Christianborg.

Namibia – Known for its Safari Destinations
Namibia – Known for its Safari Destinations
Situated on the edge of two deserts, Namibia charms the traveler with dramatic scenery. There are more than enough popular nature hiking destinations in the country. In addition to wildlife, a tourist interested in culture can also get to know the millennia-old culture.
Namibia 2
A classic of safari destinations
According to countryaah, Namibia is located in southern Africa, bordering Angola, Botswana, South Africa and Zambia. Located on the southwest corner of the continent, the country borders on the western edge of the Atlantic Ocean.
Namibia's long and multi-stage history is still evident today. The country's population is ethnically diverse and the influences of German colonization, for example, are particularly evident in the country's capital, Windhoek. Namibia gained independence from South Africa in 1990.
The landscapes of Namibia are considered by many to be unparalleled and the country is especially known as a destination for safaris and nature trips. Namibia is home to several nature parks and protected areas, including Fisher River Canyon and the prestigious Etosha National Park.
In Namibia which is short for NA by abbreviationfinder, you can also learn about ancient cultures, for example in the petroglyphs of Twyfelfontein.
Heat and drought
Namibia has a predominantly hot and dry climate, with an average daytime temperature of 30 degrees. Indeed, there are two desert areas in the country: the Namib and Kalahari deserts.
The hot rainy season lasts from January to March. The driest, on the other hand, is from July to September. The most pleasant travel time is often between these periods. The best travel time for safari tourism is during the dry season from May to September.
A fabulous safari destination
Nature tourists thrive in Namibia, as the country is especially known for its magnificent safari destinations. There are several nature parks in the country, such as the deserted Namib-Naukluft National Park and the Waterberg National Park, known for its animals.
However, Namibia's most famous natural park is Etos

Beijing, Mar 2 (IANS/EFE) Authorities in the central Chinese province of Henan inaugurated a road that is designed to play music as vehicles pass over it, the media said.
Hundreds of narrow ribbons are arrayed across a 300-meter stretch of the road in such as way as to play a tune as vehicles pass.
The vehicles must be travelling at a minimum speed of 40 kph to correctly sound the notes.
The road, located inside the Changge nature reserve, plays either the Chinese national anthem or the traditional favourite "Molihua" (Jasmine), depending on which direction the vehicles are moving.
It is China's first musical road, though similar thoroughfares exist in Japan, South Korea and Denmark, where the idea of turning a road into a musical instrument originated in 1994.
The Danes who built the first tuneful road dubbed it the "asphaltophone".
California once had its own musical road, but authorities had to repave it after area residents complained about constant noise as some drivers were driving back and forth just to make the song play.

Choosing the best method for verbal autopsy (VA) requires the appropriate metrics to assess a given method's performance, and researchers from IHME and the University of Queensland undertook a study to determine these metrics.
Because there are many different methods of performing VA, including physician review and computer-automated methods, there needs to be a way to evaluate the performance of each method. Currently used metrics to assess performance of VA methods, such as sensitivity, specificity, and cause-specific mortality fraction error, do not provide a robust basis for comparing methods. This study was designed to test metrics to compare the performance of all types of VA methods to help identify the best methods for estimating causes of death in a population.
The authors show that VA methods need to be evaluated across a set of test datasets with widely varying cause-specific mortality fraction composition. They propose two metrics for assessing the performance of a given VA method. For assessing how well a method does at individual cause of death assignment, they recommend the average chance-corrected concordance. For testing how well a method does across a population, the authors recommend testing the accuracy of cause-specific mortality fractions. Performance of a VA method in estimating cause-specific mortality fraction by cause can be determined by examining the relationship between the estimated cause-specific mortality fraction calculated by a VA method and the true cause-specific mortality fraction in a population.
The authors performed simple simulations of populations to demonstrate that most metrics used in VA validation studies are sensitive to the cause-specific mortality fraction composition of the dataset being used to test a VA method. They also conducted simulations to show that the composition of the test dataset must be varied, demonstrating that an inferior method for assessing VA can actually produce better results than a superior method on the basis of only one test dataset.
The metrics examined in this study are crucial for objective assessment of the range of VA methods currently in use. By utilizing the most robust metrics available, the best methods will be discovered in order to most accurately determine causes of death in populations without vital registration systems. These metrics will provide a basis of comparison so that different VA methods can be compared across different studies and in different populations. These standardized metrics will also facilitate innovation of new methods by providing a clear answer if a new method is leading to improved performance in assigning causes of death through VA.

The purpose of this study was to investigate the level of adherence to antipsychotic prescription medication in a well-defined homeless cohort over a 15-year period. We hypothesized that adherence would be well below the recommended threshold for clinical effectiveness (80 %), and that it would be strongly associated with modifiable risk factors in the social environment in which homeless people live.Linked baseline data (including comprehensive population-level administrative prescription records) were examined in a subpopulation of participants from two pragmatic-randomized trials that investigated Housing First for homeless and mentally ill adults. Adherence to antipsychotic medication was operationalized using the medication possession ratio. Multivariable logistic regression was used to estimate effect sizes between socio-demographic, homelessness-related and illness factors, and medication possession ratio.Among the 290 participants who met inclusion criteria for the current analysis, adherence to antipsychotic prescription was significantly associated with: history of psychiatric hospitalization; receipt of primary medical services; long-acting injectable antipsychotic formulations; and duration of homelessness. Mean medication possession ratio in the pre-randomization period was 0.41. Socio-demographic characteristics previously correlated with antipsychotic non-adherence were not significantly related to medication possession ratio.This is the first study to quantify the very low level of adherence to antipsychotic medication among homeless people over an extended observation period of 15 years. Each of the four factors found to be significantly associated with adherence presents opportunities for intervention. Strategies to end homelessness for this population may represent the greatest opportunity to improve adherence to antipsychotic medication.

Simple Guide to Cosmetic Clay Types & their Uses!
Updated: Jul 24, 2020
There is an endless number of ways in which to use cosmetic clays, and we encourage you to find your creative outlet!
BENTONITE CLAY Bentonite clay is composed of volcanic ash sediments that have been weathered over a long period of time. Sodium bentonite clay is known for its swelling properties, as it acts like a sponge when mixed with water. This clay is very popular for facial masks, foot baths, or bath soaking blends.
Dry Characteristics: The dry clay has a neutral scent and a pale, off-white color. The texture is slightly grainy, but it smooths out when pressed between the fingers. While it does leave something of a powdery coating behind when brushed off, the dry clay doesn't stick to skin too much.
Wet Characteristics: When wet, the clay paste is off-white in color with a smooth consistency. If liquid is added in too slowly, clumps will form, and the use of a whisk is helpful for keeping a smooth consistency. This wet clay spreads smoothly on skin, and its thick texture is reminiscent of cooked oatmeal.
Bowls and spoons with wet and dry bentonite and French green clays.
FRENCH GREEN CLAY French green clay is so named because some of the first recorded deposits of this clay were found in France, although it is now known to be found in many different spots around the globe. This fine-textured clay takes its verdant color from decomposed plant matter. Many people find French green clay helpful for occasional blemishes, and it is generally used by those with average to oily skin.
Dry Characteristics: French green clay has a neutral earthy aroma and pale green color. This clay doesn't "puff" (create a cloud of fine mist) out of the bag and has a fine texture, with a slight graininess.
Wet Characteristics: When water is added, the paste of this clay tends to have a slight lumpiness. Be sure to mix slowly and thoroughly with a whisk when adding liquid for smoother clay preparations. This clay has a somewhat darker green hue when moistened then in its dry form. The texture has a tendency to be a bit grainy when applied to the skin and is similar to the Rhassoul clay in consistency.
FULLER'S EARTH CLAY Fuller's earth clay has very strong oil absorbing abilities, and because of this, it is recommended for those with very oily skin. This clay is also helpful in stain removal and has mild natural bleaching properties.
Dry Characteristics: The dry clay has a lightly earthy scent and an off-white to greenish and tan color. The texture is fine and powdery. It is also very lightweight, so watch out, it can get everywhere!
Wet Characteristics: Fuller's earth clay is very smooth and easy to mix with liquids. The color is dark grey to dark tan, and it retains a fairly thick consistency when wet.
Plate with 4 sections, filled with the earth-toned clays Fuller's earth and rhassoul.
RHASSOUL CLAY Rhassoul clay is a fine, red-colored clay from Morocco that has been used for centuries in the realm of natural skin care. While it will still absorb oils from the skin, it is much gentler than many other clays and is typically recommended for more sensitive or mature skin types.
Dry Characteristics: When dry, this clay has a light reddish-brown color and a fine texture; its slight grain feels similar to French green clay. However, unlike French clay, its lightness gives it a tendency to slightly puff out of an opened bag.
Wet Characteristics: This clay mixes easily into water to create a darker, red-brown colored paste without lumps. It still retains a slight graininess, though this goes away as the clay absorbs water. It's easy to smooth onto skin and has a thin consistency when spread out.

WHITE COSMETIC CLAY White cosmetic clay (aka Kaolin clay), is not as absorbent as other clays, making it appropriate for skin that tends to be drier or more sensitive. Often, this clay is found as an ingredient in mineral makeup.
Dry Characteristics: This clay has a neutral scent with a light tan color that can vary to off-white. The texture is very fine and soft, and it will coat skin with a thin powdery layer when handled.
Wet Characteristics: When liquid is added, this clay takes on a much darker tan color. The texture remains fine and mixes easily with water, and it is smooth and grit-free.

How to Make Date Paste
Many of our desserts and baking recipes rely heavily on date paste as a replacement for sugar. Because date paste includes the same nutrients you find in dates, it brings more nutrition to a dish than refined sugars. Date paste, however, is not easily available in most major grocery stores, which might leave you scratching your head. Never fear! Date paste is just date puree, and it's easy to make. Here are some tips for getting good results.
Apple-Date Torte
Apple-Date Torte is a wonderful dessert for trying out date paste because it's very forgiving where consistency is concerned.
1. Choose your dates.
For the best health benefit, look for whole, unsweetened dates. The ingredients label on the package should say only "dates." Some dried or chopped, candied dates contain added sugar, which you don't need.
2. Choose your amount.
Estimating your quantity is tricky, since date sizes vary by type and your ultimate volume will also depend on how much water you add. As a general rule of thumb, however, you will get approximately 1 cup of date paste for 12 Medjool dates.
3. Soak your dates.
Straight up dates will produce a paste thick enough to jam most blenders and getting a smooth consistency can be challenging. Cover your dates with warm water for 1 hour, then drain the liquid off completely, reserving the liquid.
4. Puree the dates.
Using the most powerful blending tool in your kitchen (blender, food processor, whatever you own that's strongest), puree the dates. If you're having trouble getting them to a nice paste consistency (think tomato paste for comparison), add in just enough water to reach a workable consistency.
5. Store the extra.
Because amounts can be challenging to adjust, it's not a bad idea to make date paste in a larger batch than you expect to need. Measure out 1/4 cup increments onto a parchment covered baking sheet and cover loosely with plastic wrap. Freeze for 4-6 hours, then transfer to a freezer bag for later use.

A difference equation model for the dynamics of a semelparous size-structured species consisting of juvenile and adult individuals is derived and studied. The adult population consists of two size classes, a smaller class and a larger more fertile class. Negative feedback occurs through slowed juvenile growth due to increased total population levels during the developmental period and consequently a smaller adult size at maturation. Intra-specific competition coefficients are size dependent and measure the strength of intra-specific competition between juveniles and adults. It is shown that equilibrium states in which adults and juveniles occur together at all times are in general destabilized by significantly increased juvenile vs adults competition with the result that stable periodic cycles appear, in which the generations alternate in time and hence avoid competition. This result supports the tenet that intra-specific competition between juveniles and adults is destabilizing. Exceptions to this destabilization principle are found, however, in which populations exhibiting non-equilibrium, aperiodic dynamics can be equilibrated by increase competition between juveniles and adults. This occurs, for example, when adult fertility and competition coefficients are significantly size class dependent.

For the Star Trek: Voyager episode of the same name, see "Dragon's Teeth".
Dragon's teeth was a phrase used in ancient Greek mythology.
In 2376, Captain Kathryn Janeway, along with the Vaadwaur Gedrin and Commander Chakotay discovered numerous Vaadwaur soldiers in stasis, from the year 1484. After seeing them, Chakotay told of the myth of dragon's teeth, which was the story of when a dragon was killed in battle, its teeth were spread throughout a battlefield. The teeth then took root and warriors sprung from them to continue fighting. (VOY: "Dragon's Teeth")

Dental Aptitude Test Program
The Dental Aptitude Test (DAT) Program is conducted by the Canadian Dental Association (CDA), in coordination with the American Dental Association, and has been in operation on a national basis since 1966.
As a dental school applicant, you are encouraged to participate in the DAT well in advance of applying to dental school. Ideally, you should take the DAT exam at least one year before entering dental school.
Submission of DAT scores is an admission requirement of most of the 10 Canadian dental schools, though not all the schools require results from the Manual Dexterity Test. Canadian DAT scores are accepted by most U.S. dental schools, but because the U.S. DAT does not include a manual dexterity component, results of the U.S. DAT cannot be used for admission to Canadian dental schools. For exceptional circumstances, contact the dental school regarding their possible acceptance of U.S. DAT scores.
Examinations are held twice a year, in November and February, at various test centres across Canada. The testing program is designed to evaluate general academic ability, comprehension of scientific information, twoand three-dimensional visual perception and manual dexterity.
While all Canadian dental schools require applicants to submit DAT scores as part of the admission process, the test results are only one factor considered in evaluating the admission potential of an applicant. The relative importance of DAT scores in evaluating the admission potential of an applicant is determined by each dental school and is not regulated by the DAT Program.
Registration for the DAT is not an application to dental school. Information on admission requirements of individual dental schools must be obtained directly from each dental school.
DAT regulations, guidelines and fees are subject to change without notice.
Information for Dental School Applicants
Pre-Dental School Requirements
To complete an application for entry to a dental school, contact the school(s) of your choice directly and return the completed application according to the instructions given by the school(s) you are applying to.
There are certain basic pre-dental education courses that must be completed before enrolment in dental school. Since these requirements vary from school to school, it is essential that applicants contact the appropriate school(s) to determine specific admission requirements. Contact information for Canadian dental schools is listed on its own page.

International research commissioned by P2i, the world leader in liquid repellent nano-coating technology, reveals demand for mobile devices to be water-repellent as standard. The results come as more and more consumers put their phones at risk of moisture and corrosion damage as they go about their day-to-day activities.
The research found that many people keep their mobile phones with them for the majority of their average day, whatever they intend to do. The Spanish and British are more likely to take their mobile phones to a pub or café (88 percent and 85 percent respectively) than the French (67 percent), Germans (60 percent) or Americans (56 percent) – although it was Americans (12 percent) who were most likely to spill alcohol on their phones.
Water came top on the spillage stakes with an average 30 per cent of respondents having spilt it on their mobile phone, followed by coffee (13 percent) and tea (8 percent) in second and third places. Surprisingly, men were more likely to have spilled coffee on their phone than women (16 percent and 11 percent respectively).
Commenting on the survey results, Dr. Stephen Coulson, CTO, P2i says: "Mobile phones are not just susceptible to accidental spillages in pubs or cafes. Reflecting the increasing role that they play in our lives, this survey also found that on average phones are taken out in the rain (64 percent); in the snow (59 percent) and even into the shower (8 percent) and sauna (3 percent) – all posing a risk of the phone being exposed to moisture which can cause long term damage.
There is a very real demand for these devices to be able to keep up with thriving lifestyles. Phones are no longer left on the desk in the office but now accompany us everywhere we go." When it comes to exposing a mobile device to the outdoor elements such as sand and sea, the Spanish (77 percent) and the French (72 percent) are the most likely to take their phones to the beach. Only 47 percent of respondents from the USA take their phones with them to sit beside the sea.
Dr. Coulson adds, "It's no surprise that on average over half of all of those questioned (51 percent) expect water protection to be included as standard when buying a mobile phone. Without it, users not only need to avoid liquid coming into contact with their phones but have to consider the 'hidden' risk of moisture that can cause corrosion, damaging the phone, its components and, often more importantly, the content and data stored on it."
When asked what applications they would miss the most if their phone stopped working, the UK is clearly a nation of text fanatics, with 63 per cent of respondents citing text messaging over any other function. The findings from the other nations showed that the ability to phone people would be missed the most.
On Booth 2E58, in Hall 2, at Mobile World Congress, Barcelona, P2i will be demonstrating its Aridion technology which dramatically increases the reliability of electronic devices by protecting them from water and corrosion damage. Over nine million electronic devices are now protected by Aridion including smartphones, tablets, and hearing aids.

If you want to maintain a healthy lawn, avoid exposing it to products that contain uric acid. If your goal is to kill off a lawn in order to install a new one or replace it with something else, treating it with healthy doses of uric acid is a good way to kill the grass down to the roots and make it easy to remove.
What is Uric Acid?
Uric acid occurs naturally in the bodies of people, dogs and other mammals and is excreted in waste material. Uric acid contains large amounts of nitrogen and salt, materials mammals need to survive, but only up to certain point. Whatever the body doesn't need is excreted. Waste material contains varying amounts of uric acid. Uric acid is not harmful in small amounts, but can damage grass and other plants in larger, more concentrated doses.
A common source of uric acid for many lawn owners is the family dog. Dog urine contains high levels of uric acid, and dog owners with lawns are likely to see the familiar brown spots caused by dog urine. The problem is more common with female dogs that squat to urinate, since they deposit large amounts of urine in a concentrated area. Cat urine also contains uric acid, but few cats produce enough urine to do damage to grass. Fertilizer and manure also contain uric acid and using too much on a lawn is a sure way to kill it, which is why fertilizer labels contain warnings cautioning against overuse.
What Causes the Damage?
Uric acid damages grass because of its nitrogen and salt content. The salt coats the indivdual blades of grass and slowly leaches water from them, causing the grass to eventually die from dehydration. Nitrogen is less harmful, but an over-abudance of nitrates has the same effect on grass and can kill it by draining its water supply. A hot dry climate can accelerate this process and allow uric acid to damage or kill a lawn faster.
Though all types of grass are susceptible to damage from uric acid, some are more vulnerable than others. Kentucky bluegrass and perennial rye grass are two types that are easily killed off by uric acid. Hardier types such as Bermuda grass and St. Augustine grass are not damaged as easily and grow back more quickly when they are exposed to uric acid. Small amounts of dog urine don't contain enough uric acid to damage grass and can actually help it grow faster due to the additional nitrogen. The grass in the exposed area will grow taller and darker than the surrounding area.
Killing a Lawn with Uric Acid
The best way to get rid of a lawn using uric acid is through the liberal use of fertilizer. Choose any lawn care fertilizer and dose your lawn with three to four times the amount recommended on the label. Wait a few days, repeat the process, and the lawn will be on its way out. The combination of the salt and nitrates in the uric acid will dehydrate the leaves and infiltrate the roots with a buildup of sodium, bicarbonate and boron, making them unable to absorb nutrients.

This is true for the given query, but not in general.
Assume you have in an InnoDB table and an index on (b,c) and 'a' is
the primary key. In this case:
select c from foo where a=1 and b = 1
I't better to scan the index (b,c) than scan the primary key as you
get all key parts from this index, but it's much less to scan as you
don't have to access all the other columns from the table.

Update[symbol] tells Mathematica that hidden changes have been made which could affect values associated with a symbol.
Update[ ] specifies that the value of any symbol could be affected.
Update manipulates internal optimization features of Mathematica. It should not need to be called except under special circumstances that rarely occur in practice.
One special circumstance is that changes in the value of one symbol can affect the value of another symbol by changing the outcome of Condition tests. In such cases, you may need to use Update on the symbol you think may be affected.
Using Update will never give you incorrect results, although it will slow down the operation of the system.

How reliable is the Polar Fitness Test
Validity of a test means that the test measures what it is supposed to measure and not something else. The Polar Fitness Test was originally developed on 305 healthy Finnish men and women in a study, where VO2max prediction was developed using artificial neural network analysis. The correlation coefficient between the laboratory measured VO2max and the neural network prediction value was 0.97 and the mean error in the VO2max prediction was 6.5 % which is good compared to any other predictive tests of VO2max.
In further development of the test, 119 fitness measurements of healthy American men and women were included in the final development of the neural network, making a total of 424 subjects. Based on these results the artificial neural network was modified into Polar Fitness Test. The test was validated in a study on 52 healthy men, who didn't belong to the group on whom the test was developed. The mean deviation in the Polar Fitness Test prediction was less than 12 %. The validity of the Polar Fitness Test is considered to be good.
The reliability of a test is a measure of how consistent and reproducible the test results are on consecutive trials. The reliability of the Polar Fitness Test is good. When 11 subjects repeated the test in the morning, in the middle of the day and in the evening during eight days, in both sitting and laying positions, the average individual standard deviation of consecutive test results was less than 8 % from the individual mean value. The standard deviations calculated separately for each time of the day were all smaller than the standard deviation of all results. This indicates that the test can be conducted at any time of the day but it should always be repeated at about the same time.

ESTIMATED READING TIME – 1:40
Learning goals for this aptitude
– Understand why diagnosis is important to talent optimization.
– Be able to list and describe the three actions associated with the diagnose aptitude.
– Use the associated maturity model to identify an organization's level of maturity for the diagnose aptitude.
Diagnose is part one of the four-part talent optimization framework. This is where you'll measure critical people data, analyze that data in the context of your business, and prescribe remedies as needed.
Why diagnosis is important to talent optimization
Consider how a medical doctor uses reliable lab results to measure a person's overall health, evaluates the data in the context of any problems, and acts to correct any issues. A talent optimizer employs a similar methodology. Best practice for a business is to identify potential problems proactively by diagnosing preventatively; this is what smart organizations do. But there will always be gaps between what you think will happen and what actually happens. This is why companies often diagnose in response to problems (e.g., "not meeting sales goals" or "high turnover.")
Diagnose is a method for pinpointing the root cause of gaps—your underlying people problems—and making strategic changes or changes to day-to-day execution. The insights you uncover in diagnose typically point back to the other three aptitudes of talent optimization: design, hire, and inspire. Businesses that collect and analyze their people data and then make necessary adjustments proactively will enjoy a more productive and engaged workforce; instead of letting problems build up and fester, addressing them quickly shows employees they care.


Crown Lengthening Procedure for Short Crowns
Home > Periodontics > Crown Lengthening procedure for short crowns
FAQ's :
1. How long does it take for a crown lengthening to heal?
It usually takes 7 to 10 days. If bone trimming is done then Your gums should heal for aboutone to three months before the tooth is prepared for the final crown.
2. What is the procedure for crown lengthening?
3. Is a crown lengthening necessary?
A crown lengthening can reduce the bone level and gum tissue in order to gain better access to your tooth. When a tooth breaks, or if there is severe decay, the remaining healthy tooth area is reduced and this can affect the potential for a successful tooth restoration.
4. Does a crown lengthening hurt?
The dentist removes a small amount of gum and bone around the tooth, and several weeks are needed for healing. The new "taller" tooth is then prepared for the crown. The crown lengthening procedure starts with anesthesia, and then the periodontist removes excess gum tissue to expose more of your teeth.

From May 1, 2023, the size of the basic calculation value used to calculate the number of state fees will increase in Uzbekistan, including for actions with objects of intellectual property.
The size of the basic estimated value increases by 10% (from 300,000 to 330,000 Uzbekistani sum). Accordingly, all fees for filing applications, registration, and other actions with trademarks, patents, and industrial designs in Uzbekistan will increase by the same amount.
In particular, at the current exchange rate of the Uzbekistani sum, the state fee for applying for TM in one class will be about $700, and $235 for each additional class. Read more


TCPView works on Windows NT/2000/XP and Windows 98/Me. You can use TCPView on Windows 95 if you get the Windows 95 Winsock 2 Update from Microsoft.
Using TCPView
When you start TCPView it will enumerate all active TCP and UDP endpoints, resolving all IP addresses to their domain name versions. You can use atoolbar button or menu item to toggle the display of resolved names. On Windows XP systems, TCPView shows the name of the process that owns each endpoint.
Tcpvcon Usage
Show all endpoints (default is to show established TCP connections).
Print output as CSV.
Don't resolve addresses.
Source Code to Netstatp
Wonder how TCPView works? Netstatp is a program with source that demonstrates how to program some of TCPView's functionality. It shows how to use IP Helper interfaces, documented in MSDN, to obtain a list of TCP/IP endpoints. Note, however, that netstatp doesn't show process names on NT 4 and Win2K like TCPView and TCPVCon.

Brisker uses a gentle heating element to warm the interior temperature to ~120 degrees Fahrenheit. Warmer air spreads moisture out, so items inside the Brisker dry out and stay crunchy.
This all works because of the principles of relative humidity. With the air inside the Brisker about 40-50 degrees warmer than room temperature in your kitchen or pantry, humidity and moisture decreases inside of the Brisker relative to the humidity in your kitchen.
Here's a neat video explaining how relative humidity works.

The Final Act of Living: Reflections of a Long-Time Hospice Nurse
The Final Act of Living: Reflections of a Long-Time Hospice Nurse is an end of life book, a resource that reads like a novel, yet has the content of a textbook. It is available in hard copy and ebook versions.
Barbara wrote this book following years of not only being at the bedside of hundreds of persons at their moment of death but with them as their hospice nurse in the months before their actual death. From the stories and experiences she shares you will see that death unfolds as a process, within a framework, and doesn't simply happen.
By being at the bedside during a time in our culture when a person dying was usually in the hospital, in a private room and very much alone, Barbara brings to the forefront of our consciousness the dynamics of dying from disease and old age.
We will all be affected by dying, death, and grief at some time in our lives. "The Final Act of Living: Reflections of a Long-time Hospice Nurse" is a book on the end of life that offers knowledge and clarity to ease the fear and misinformation about dying and death. It explores the topics of living with a life threatening illness, fear of death, understanding the signs of approaching death from disease, the dying process, stages of death, the normal grieving process, living wills, and other end of life issues.
The Final Act of Living is used as:
- A resource on end of life issues
- A reference book for everyone working with end of life issues:
nurses, social workers, chaplains, Lay ministers, counselors, and others
- A textbook in RN/LPN classes, CNA training classes, social
work classes, college and university classes
- A training handbook for hospice volunteers
- An easy read for anyone interested in dying and grief
This material may be described as an "end of life book," however as the title states, its content and philosophy are all about "The Final Act of Living."


NAME 'IO::Ppoll' - Object interface to Linux's 'ppoll()' call SYNOPSIS use IO::Ppoll qw( POLLIN POLLOUT ); use POSIX qw( sigprocmask SIG_BLOCK SIGHUP ); my $ppoll = IO::Ppoll->new(); $ppoll->mask( $input_handle => POLLIN ); $ppoll->mask( $output_handle => POLLOUT ); $SIG{HUP} = sub { print "SIGHUP happened\n"; }; sigprocmask( SIG_BLOCK, POSIX::SigSet->new( SIGHUP ), undef ); # If a SIGHUP happens, it can only happen during this poll $ppoll->poll( $timeout ); $input_ev = $poll->events( $input_handle ); DESCRIPTION 'IO::Ppoll' is a simple interface to Linux's 'ppoll()' system call. It provides an interface that is drop-in compatible with IO::Poll. The object stores a signal mask that will be in effect during the actual 'ppoll()' system call and has additional methods for manipulating the signal mask. The 'ppoll()' system call atomically switches the process's signal mask to that provided by the call, waits identically to 'poll()', then switches it back again. This allows a program to safely wait on either file handle IO or signals, without needing such tricks as a self-connected pipe or socket. The usual way in which this is used is to block the signals the application is interested in during the normal running of code. Whenever the 'ppoll()' wait is entered the process signal mask will be switched to that stored in the object. If there are any pending signals, the Linux kernel will then deliver them and make 'ppoll()' return -1 with 'errno' set to 'EINTR'. If no signals are pending, it will wait as a normal 'poll()' would. This guarantees the signals will only be delivered during the 'ppoll()' wait, when it would be safe to do so. CONSTRUCTOR $ppoll = IO::Ppoll->new() Returns a new instance of an 'IO::Ppoll' object. It will contain no file handles and its signal mask will be empty. METHODS $mask = $ppoll->mask( $handle ) Returns the current mask bits for the given IO handle $ppoll->mask( $handle, $newmask ) Sets the mask bits for the given IO handle. If '$newmask' is 0, the handle will be removed. $ret = $ppoll->poll( $timeout ) Call the 'ppoll()' system call. If '$timeout' is not supplied then no timeout value will be passed to the system call. Returns the result of the system call, which is the number of filehandles that have non-zero events, 0 on timeout, or -1 if an error occurred (including being interrupted by a signal). If -1 is returned, '$!' will contain the error. $bits = $ppoll->events( $handle ) Returns the event mask which represents the events that happened on the filehandle during the last call to 'poll()'. $ppoll->remove( $handle ) Removes the handle from the list of file descriptors for the next poll. _USER_ = $ppoll->handles( $bits ) Returns a list of handles. If '$bits' is not given then all of the handles will be returned. If '$bits' is given then the list will only contain handles which reported at least one of the bits specified during the last 'poll()' call. $sigset = $ppoll->sigmask Returns the 'POSIX::SigSet' object in which the signal mask is stored. Since this is a reference to the object the 'IO::Ppoll' object uses, any modifications made to it will be reflected in the signal mask given to the 'ppoll()' system call. $ppoll->sigmask( $newsigset ) Sets the 'POSIX::SigSet' object in which the signal mask is stored. Usually this is not required, as a new 'IO::Ppoll' is initialised with an empty set, and the 'sigmask_add()' and 'sigmask_del()' methods can be used to modify it. $ppoll->sigmask_add( _USER_ ) Adds the given signals to the signal mask. These signals will be blocked during the 'poll()' call. $ppoll->sigmask_del( _USER_ ) Removes the given signals from the signal mask. These signals will not be blocked during the 'poll()' call, and may be delivered while 'poll()' is waiting. $present = $ppoll->sigmask_ismember( $signal ) Tests if the given signal is present in the signal mask.

Generate Objects from Xml Files
Recently needed some quick method to use objects generated from an existing xml file without bothering to create an xml schema for it.
After a few attempts and searching for explanations why a simple task like this wouldn't work, finally put the steps together:
1. Use VS2008 CommandPrompt Tool and run :
xsd.exe xmlNameFile.xml /outputdir:DirName
2. The above will generate xsd schema in the directory (.xsd file)
3. Use xsd tool again in the VS CommandPrompt to generate the classes from the new schema :
xsd.exe NewSchemaName.xsd /c /n:YourNamespace
This will generate a class file that you can use in your project but be aware of the following :
For parent elements in xml it will automatically generate a field as a multidimensional array, i.e. Items[][] with the XmlArrayItemAttribute("TagName", typeof(Items) but as Items is multidimensional it won't cope with it, even if one changes the type to typeof(Items[]) these are filled with null.
4. You need to change the whole into a one dimensional array :
private Items[] itemsField;
XmlArrayItemAttribute("TagName", typeof(Items)
This will fill the array with all the nodes that are under TagName automatically.
5. Then you can use a Deserialization method to get the whole object, like :
public object DeSerializeObject(string s, Type t)
 Stream xmlStream = new MemoryStream(s.Length);
 StreamWriter sw = new StreamWriter(xmlStream);
 xmlStream.Seek(0, SeekOrigin.Begin);
 XmlSerializer serializer = new XmlSerializer(t);
 return serializer.Deserialize(xmlStream);
And method usage :
Response rsp = (Response)this.DeSerializeObject(doc.InnerXml, typeof(Response))
The result is an object having the structure of the xml file provided at the beginning.

Assortment analysis: identifying weak links

Assortment analysis: identifying weak links
How, using assortment analysis, can you understand which product categories are the "weak link" that constantly create stocks? The most powerful way is to use ABC market analysis based on the Pareto principle. Clever Fashion's experts tell you how to apply this principle to the assortment of a shoe store.
(Only part of the article "To make the leftovers become sweet" is published here. Read the full version of the material in Shoes Report # 108).
The Pareto principle says that 20% of the effort gives 80% of the result, and in relation to the assortment implies that the largest amount of profit (80%) comes from a fairly small group of products and customers (20%). Using the Pareto principle, all inventories can be divided into 3 main categories:
And - especially valuable goods, which make up 20% of stocks in a warehouse and form 80% of sales;
B - goods of average value, comprising 30% of stocks in a warehouse and 15% of sales;
C - the least valuable goods: 50% of stocks in a warehouse and 5% - sales.
Before applying Pareto principle to product categories, analyze sales at a point of sale. To do this, you need to divide all the parameters and resources that you encounter when working into groups according to the degree of importance and effectiveness. This is especially convenient with tables. To compile them, do the following:
Identify the ones that matter to your business objectsfor example, customers (regular, casual, wholesale customers, those who are looking for rare sizes or models, etc.), suppliers (seasonal shoes, exclusive shoes, discounted shoes, etc.), groups and subgroups of goods.
· Determine what parameters you will evaluate efficiency these objects for your store. This may be the volume of sales provided by this object, the total income earned from the object, the average inventory, the number of sales units per object, the number of orders from the object, etc. For example, you analyze sales and you see that a certain regular group of customers buys the entire size range of certain shoes every season, another group - only a few popular models, and another customer group is focused on a particular brand. Or, looking at the income earned, you see that from one group of goods profit is 3 times more than from another. Make several tables for each such object, and consider all its parameters in the table. The numbers may surprise you!
· Sort Objects in importance and profitability for your store. These tables will help to understand with whom cooperation is more effective. Do not forget to analyze the ratio of the tables to each other - this way you can find that, for example, a certain group of customers buys the entire size range each time, but this does not bring the highest percentage of profit due to the pricing policy. And some supplier doesn't deliver the most popular models, but it is them who are guaranteed to buy regular customers: in this way, the products of this supplier practically do not form residues in the warehouse.
· After analyzing all the data, matching all the numbers and graphs, go to the definition priority product groups using the Pareto principle.
Analiz objektov
How exactly to apply the Pareto principle to the information obtained from the tables? As noted above, group A - these are the models and sizes that bring the main part of the profit, suppliers whose products diverge the fastest, and customers who provide most of the turnover. Therefore, in the final data, objects of this group are very easy to notice: these are the most popular models in the collection, the most popular sizes, shoes that most meet the demand of buyers and suppliers who offer just such products.
The goods of group A practically do not form residues in the warehouse, therefore also look for objects that are sold as quickly and fully as possible. In general, all the products you selected in this group will amount to no more than 20% of the total.
Next Popular Products group B form in comparative tables about 30%. These are objects that provide a good average level of sales - something that will most likely be sold out, but a certain number of pairs can get stuck in the warehouse: sandals will linger in the fall, and several pairs of boots will also stand in the spring.
Products group C they generate income less than others, but more often than others they turn into long-term stock balances. This is usually a specific product - amateur shoes, extreme sizes, exotic models. Such products also find their buyer, but this happens extremely slowly.

In queueing theory, a discipline within the mathematical theory of probability, traffic equations are equations that describe the mean arrival rate of traffic, allowing the arrival rates at individual nodes to be determined. Mitrani notes "if the network is stable, the traffic equations are valid and can be solved.":125
In a Jackson network, the mean arrival rate at each node i in the network is given by the sum of external and internal arrivals. If external arrivals have rate and the routing matrix[clarification needed] is P, the traffic equations are, (for i = 1, 2,..., m)
This can be written in matrix form as
and there is a unique solution of unknowns to this equation, so the mean arrival rates at each of the nodes can be determined given knowledge of the external arrival rates and the matrix P. The matrix I − P is surely non-singular as otherwise in the long run the network would become empty.
In a Gordon–Newell network there are no external arrivals, so the traffic equations take the form (for i = 1, 2,..., m)
