RF Sputtering Method Preparing Nanometer Tungsten Disulfide Membrane
Tungsten disulfide is an excellent solid lubricant material, it has high application value in the field of super solid lubrication.
Tungsten disulfide membrane have layered structure, it has lower hardness and better stability under high temperature, it is suitable to be used as a solid lubricant for friction parts in special environment. There are three main methods for preparing tungsten disulfide membrane which include RF sputtering method, reactive magnetron sputtering method, chemical deposition method.
The method of RF sputtering crystal growth is the method of using RF sputtering to make the components of the crystal material gasified and then recrystallized to grow the crystal. RF sputtering is a sputtering deposition method suitable for all kinds of metal and nonmetal materials, the frequency range is 5~30MHz, the frequency of 13.56MHz is commonly used internationally. It is mainly used to prepare thin membranes and also to prepare small size crystals.

WS2 powder with 99.99% purity was prepared by cold pressing to form WS2 target, the surface of the stainless steel substrate is mechanically polished, and the surface is cleaned by ultrasonic wave. The background vacuum is 3 x 10-3Pa, fill in argon to the working pressure 1Pa, sputtering power 30W, deposition time for 1hour, depositing WS2 on a substrate to form a thin membrane.
The surface of tungsten sulfide membrane prepared by RF sputtering method is smooth, no voids and gaps were observed under SEM, it has high density and good quality, the surface morphology of the samples with different working pressure, different sputtering power and deposition time is similar, and no obvious changes.
Compared with other sputtering methods, RF sputtering method has a wide range of target materials, better advantages of high deposition rate, the RF power can be effectively input by adjusting the discharge impedance and the power impedance matching.
The membrane obtained by this method are generally amorphous. But by strictly controlling the sputtering pressure, power and other technological parameters, the sputtering method is still an important method for the preparation of the laboratory or the production of small workpieces.

Review on the Effectiveness of Tungsten Disulfide and Molybdenum Disulfide Lubricant
 Solid lubrication is a method of coating or plating on the surface of the friction pairs to form a thin film and reducing friction.
tungsten disulfide and molybdenum disulfide image
The technique of using solid lubricants to lubricate is called solid lubrication. Tungsten disulfide and molybdenum disulfide are excellent solid lubricating materials, in the field of ultra-solid lubrication has a very high value, this technology is applied to the hard disk drive bearing of computer, such as rotation and sliding in ultra high vacuum system.
Molybdenum disulfide has a graphite-like structure, molybdenum and sulfur through the covalent bond to form a hexagonal structure, each molybdenum is surrounded by six sulfur atoms, the molecular layer surface only sulfur atoms, each layer molecular layer thickness of 0.626nm. The thermal stability of MoS2 is better in the air environment lower than 400 degrees. When the temperature is higher than 400 degrees, MoS2 will be oxidized to MoS3 in a short time, MoS3 is a granular material with higher hardness, attached to the friction surface of abrasive formation. But in a vacuum and inert gas environment, the structure of MoS2 at 1100 DEG C can keep steady.
Tungsten disulfide WS2 also has a hexagonal lamellar structure similar to molybdenum disulfide. Tungsten atoms and sulfur atoms covalently bonded, the molecular layer surface only sulfur atoms, between the sulfur atoms between the weak molecular bonds. WS2 is insoluble in almost all media, including acids, alkalis, oils and water, but is sensitive to free gaseous fluoride, hydrofluoric acid and hot sulphuric acid. Compared with MoS2, the thermal stability of WS2 is better than that of MoS2, and the decomposition temperature of WS2 is 510 °C in the air. In 539 degrees will be rapid oxidation, decomposition temperature in vacuum and inert gas is 1150 DEG C. Compared to the molybdenum disulfide, more widely applicable temperature range WS2.
Several domestic and foreign lubricant manufacturers have tungsten disulfide, molybdenum disulfide and graphene three lubrication performance comparison, through the test found that tungsten disulfide is not only stronger than molybdenum disulfide, stronger than graphene. In addition, in the high radiation operating environment, tungsten disulfide has a higher anti-radiation properties, can adapt to more complex operating environment, therefore, the major manufacturers are tungsten disulfide lubricant showed a more intense interest in production.
In the United States, aerospace industry, mainly used as MoS2 solid lubricating material, this is because the United States is the production of molybdenum power, convenience with local resources. In China, we have not only molybdenum more tungsten, relative to molybdenum, tungsten, whether it is heat resistance, physical and chemical stability, or radiation resistance are better than molybdenum, so tungsten disulfide lubricant will be better choice.

Electrical Properties of Tungsten Disulfide
The structure of tungsten disulfide is a hexagonal layered structure with excellent electrical properties.
In tungsten disulfide, the interaction between the W atoms in the layer and the surrounding S atoms is strong, and the interaction between the tungsten disulfide layer and the layer is weak.

The thermal stability of two tungsten sulfide is stronger than that of molybdenum disulfide. The temperature range is wide, and it is not easy to decompose. Oxidation occurs at 539 degrees centigrade. Therefore, tungsten disulfide is an excellent semiconductor material for indirect bandgap semiconductors. When the thickness of tungsten disulfide is reduced to a single layer, it changes into a direct band gap, which means that tungsten disulfide can effectively pass through the bandgap transition absorb or emit photons. The band gap of monolayer tungsten disulfide is about 2eV. This electrical performance characteristic is the main advantage of tungsten disulfide in semiconductor tubes, transistor applications that can go beyond graphene.
In fact, graphene has a very important defect in the field of semiconductors, which is the lack of band gap between electrons. In theory, graphene has very high mobility electrons that allow it to process data at very high rates, although it's very fast, there's no electron gap, and it's hard to turn it off once it starts to transmit data, this seriously hinders the logical operation, because all the problems in logic operations are open and close. While the two tungsten sulfide with planar high current switch, a higher than the mobility and the effective conductivity modulation performance, there is no logic problem, which can completely replace graphene in transistors, lighting diodes and optical sensors and other devices. The future, even now produce more than 100 times the calculation function of CPU, the use of the material is probably two tungsten sulfide.
In addition, tungsten disulfide also has a very strong photoluminescence properties, can replace the traditional transparent electrode materials and graphene, as a liquid crystal display, touch screen, solar cells and other equipment, transparent electrodes, with the addition of tungsten disulfide, the future of such equipment or will have a folding function.

National Teachers Initiative
The National Teachers Initiative is a project of StoryCorps, the American oral history project. Each month this school year, "Weekend Edition Sunday" will celebrate stories of public school teachers across the country.
Learning Works charter school in California takes an unorthodox approach to getting young people to graduate. Students who had previously dropped out get mentors who help with everything from getting to class on time to staying up late studying. Now, some of those who graduated are helping others.
December 25, 2011 Teacher John Hunter invented the World Peace Game to get his elementary students to think about major world issues. He also wanted to teach them compassion and kindness. At least two of his former students are on the path he helped to pave.
October 30, 2011 Ayodeji Ogunniyi's family came to the U.S. from Nigeria in 1990. His father worked as a cab driver in Chicago, and he always wanted his son to become a doctor. But while Ogunniyi was studying pre-med in college, his father was murdered on the job. At that point, he says, his life changed course.
September 25, 2011 As a middle-school student in the '80s, Lee Buono stayed after school one day to remove the brain and spinal cord from a frog. He did such a good job that his science teacher told him he might be a neurosurgeon someday. That's exactly what Buono did.
September 25, 2011 StoryCorps is honing in on lessons about learning with a new project for the academic year called the National Teachers Initiative. It'll feature conversations with teachers across the country — teachers talking to each other, students interviewing the teachers who changed their lives, and more.

activities that can help regulate hyperactivity in individuals with autism?
Yes, sensory activities can play a crucial role in regulating hyperactivity in individuals with autism. Engaging in sensory activities can provide calming input and help individuals with autism regulate their sensory systems. Some effective sensory activities include deep pressure activities, such as using a weighted blanket or receiving a gentle massage, which can provide a sense of grounding and relaxation.
Other sensory activities that can help regulate hyperactivity include using a sensory swing or trampoline, engaging in water play, or playing with sensory toys like stress balls or sensory bins. It's important to observe and understand an individual's sensory preferences and sensitivities to ensure that the chosen sensory activities are appropriate and beneficial for that individual. If you're unsure about which sensory activities to try, consulting with an occupational therapist or sensory integration specialist can provide expert guidance.
4. Can medication help manage hyperactivity in individuals with autism?
Medication can be a viable option for managing hyperactivity in individuals with autism, but it should always be considered as part of a comprehensive treatment plan and in close consultation with a healthcare provider. Certain medications, such as stimulant medications, can help reduce hyperactivity and improve attention and impulse control. However, medication should always be prescribed and monitored by a qualified medical professional who specializes in autism spectrum disorder.
It's important to note that medication is not the only approach or solution for managing hyperactivity in autism. Behavioral interventions, therapy, and other strategies should also be incorporated to address the underlying causes and provide holistic support. Each individual with autism is unique, so it's crucial to work closely with healthcare professionals to determine the most appropriate and effective treatment approach.
5. How can caregivers support individuals with autism during episodes of hyperactivity?
Caregivers play a vital role in supporting individuals with autism during episodes of hyperactivity. One important factor is to remain calm and patient. Demonstrating a calm attitude can help create a more soothing environment, which can aid in regulating the individual's emotions and behaviors. It's also essential to provide clear and consistent communication, using simple and concise language to convey expectations and instructions.
Engaging in calming activities, such as deep breathing exercises or listening to calming music, can also help individuals with autism during episodes of hyperactivity. Lastly, offering reassurance and support, while acknowledging the individual's emotions, can provide a sense of security and comfort. Remember, each individual with autism is unique, so it's crucial to understand their specific needs and preferences and tailor the support accordingly.
Summary
If you have a friend or family member with autism who is hyperactive, there are things you can do to help. First, create a structured environment with consistent routines and clear rules. Make sure they have a quiet and organized space to relax. Second, provide them with plenty of physical activities to burn off energy, like going for walks or playing sports. Lastly, teach them calming techniques such as deep breathing and using a sensory tool.
Remember, everyone with autism is unique and what works for one person may not work for another. So, be patient and understanding. With love and support, you can help your loved one with autism manage their hyperactivity and live a happier, more peaceful life.

This is the practice for calculating the IFI of the pavement. The IFI has proven useful for harmonization of the friction measuring equipment. F60 and Sp have proven to be able to predict the speed dependence of wet pavement-related measurements of the various types of friction-measuring equipment.2 The two IFI parameters (F60 and Sp) have been found to be reliable predictors of the dependence of wet pavement friction on tire slip and vehicle speed.
The IFI parameters, F60 and Sp, can be used to calculate the calibrated friction at another-slip speed using a transformation equation.
The IFI model given below describes the relationship between the values of wet pavement friction FRS measured at a slip speed of S and between the friction values measured by different types of equipment.
A significance of the IFI Model is that the measurement of friction with a device does not have to be at one of the speeds run in the experiment. FRS can be measured at some S and is always adjusted to FR60. Thus, if a device can not maintain its normal operating speed and must run at some speed higher or lower because of traffic, the model still works well. In that case S is determined by the vehicle speed (V) which can be converted to S by multiplying V by the percent slip for fixed slip equipment or by multiplying V by the sine of the slip angle for side force equipment.
This practice does not address the problems associated with obtaining a measured friction or measured macrotexture.View Less
1.1 This practice covers the calculation of the International Friction Index (IFI) from a measurement of pavement macrotexture and wet pavement friction. The IFI was developed in the PIARC International Experiment to Compare and Harmonize Texture and Skid Resistance Measurements. The index allows for the harmonizing of friction measurements with different equipment to a common calibrated index. This practice provides for harmonization of friction reporting for devices that use a smooth tread test tire.
1.2 The IFI consists of two parameters that report the calibrated wet friction at 60 km/h (F60) and the speed constant of wet pavement friction (Sp).
1.3 The mean profile depth (MPD) has been shown to be useful in predicting the speed constant (gradient) of wet pavement friction.
1.4 A linear transformation of the estimated friction at 60 km/h provides the calibrated F60 value. The estimated friction at 60 km/h is obtained by using the speed constant to calculate the estimated friction at 60 km/h from a measurement made at any speed.
1.5 The values stated in SI (metric) units are to be regarded as standard. The inch-pound equivalents are rationalized, rather than exact mathematical conversions.
1.6 This standard does not purport to address all of the safety concerns, if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

VERILOG-XL: Error! Module (...) has a 'timescale directive but previous modules do not
Keywords: Verilog, Verilog-XL, timescale
Urgency: Standard
General Description:
When simulating with Verilog-XL, what does the following error mean:
The 'timescale compiler directive is optional. Designs that do not
contain this require no modification and the default of 1 ns / 1 ns is used.
However, if the design includes a 'timescale compiler directive for any
module definition, then all other modules definitions require this as well.
Otherwise, Verilog-XL flags this as an error.
The 'timescale can be declared in any file.
The UNISIMS has 100ps / 10ps.
The SIMPRIMS has 1ps / 1ps.
The glbl.v has 100ps / 10ps.
The smallest precision of all the timescale directives determines the time
unit of the simulation. For example,
'timescale 1 ns / 10 ps
module1 ();
'timescale 100 ns / 1 ns
module2 ();
'timescale 1 ps / 100 fs
module3 ();
The first timescale indicates that the time units for module1 are in multiples
of 1 ns and it is precise to 10 ps. Thus, the smallest timestep for the
simulator is 10 ps.
The second timescale is 100 ns / 1 ns. Since 1 ns is greater than 10 ps,
the smallest timestep remains 10 ps.
The third timescale is 1 ps / 100 fs. Since 100 fs is smaller than 10 ps,
the smallest simulator timestep now becomes 100 fs.

The radiology technicians at Fort Duncan are pleased to offer a better patient experience!
A new CT scanner offers patients faster and more accurate CT scans
The radiology department at Fort Duncan Regional Medical Center invested in a new CT scanner that will provide faster, lower-dose, high resolution imaging for patients. Director of Radiology Jeffrey Otto says that the new technology means an improved imaging experience for patients and more accurate scans for radiologists and physicians to use in diagnosis and treatment assessments.
Computed tomography (CT) uses a low dose of radiation to capture X-ray scans with multiple rotating sensors that produce detailed cross-sectional images of organs, bones and tissues to assess possible fractures, internal injuries, tumors, blood clots and conditions like heart disease, lung nodules and cancer.
Otto explains that the new CT machine has 10 times more sensors to produce higher quality scans in less time. "The new machine has reduced the amount of time a scan takes. It's double the speed of our previous machine, so we are much faster."
Faster CT scanning translates to shorter radiology visits and less radiation exposure for patients. Another feature is the lateral assist button that allows radiology technicians to easily adjust the position of patients in the scanner without having to physically push or pull them into place. This is important not just for patient comfort but also because the technicians are able to move patients who may be immobile because of a trauma injury.
For CT angiography scans of the heart and coronary arteries, the new machine has advanced technologies for capturing detailed images between heartbeats while diminishing the amount of time, IV contrast and radiation exposure necessary to evaluate which cardiac or vascular intervention a patient may require.
These enhancements offer patients at Fort Duncan a more comfortable imaging experience and provide more detailed results for diagnosis, which is the top priority for the radiology department.
A doctor's order is required for a CT scan, and results are provided promptly.
New cardiac catheterization lab coming to Fort Duncan!
Fort Duncan is building a cardiac catheterization lab in a 1400 square foot space beside the Emergency Department. The lab will house a ceiling mounted imaging machine that allows the cardiologist to move freely while taking X-ray scans or performing minimally invasive procedures to diagnose and treat heart disease. The upgrade will vastly improve patient experience with an anticipated opening later this year.

Gaston, K.J. 2020. Personalised ecology and detection functions. People and Nature [online early].
1. Direct interactions with nature are important for people's health, well-being and support for pro-nature policies. There is an urgent need better to understand the structure and dynamics of these interactions, and how they differ among individual people, human populations and the communities to which they belong.
2. The determinants of these interactions have two components. First are the factors that influence whether someone undertakes actions that may lead to interactions with nature (e.g. looking through a window, going for a walk, travelling to the countryside). These factors have attracted significant attention. Second are the factors that influence what nature interactions are obtained when someone is present in a situation in which these could occur. These have received little explicit attention.
3. One way of formalizing understanding, and identifying gaps in knowledge, of the second group of factors is to consider human–nature interactions in terms of detection functions. Rather than using such functions for the estimation of species abundances, the purpose for which they were originally developed, they can be reorganized as descriptors of influences on people's nature interactions.
4. This paper considers how the different variables contained within detection functions influence human–nature interactions, and in particular how the number of nature interactions a person has in a given place and time is shaped both by clearly 'nature'-associated variables, such as the number of organisms present, and also by variables that are strongly influenced by characteristics of the observer, such as how they use or explore an area and their personal nature detection abilities.
5. Many issues explored in the context of human–nature interactions are then seen to concern these component variables of detection functions, and approaches to improving the frequency of interactions seen, in effect, to be targeted at affecting change in different ones of these variables.

What is the correct standard use of glass edging machine?
by：Enkong 2019-12-10
At present, there are many glass inner grinding machines used in factories, and some are specially made for glass decoration, which are basically available, and the glass made is beautiful and accurate, so what is the correct specification of the glass edging machine? 1. The stepless transmission used by the edging machine must be in an open state when adjusting the speed, otherwise it is easy to damage the continuously variable transmission of the edging machine. 2. Precautions when using the special-shaped machine: ① whether the suction cup of the special-shaped machine Workbench is consistent or not has a great influence on the grinding effect. During assembly, the manufacturer has self-grinded the five sets of suction cup seats, and selected the suction cup glue with the same thickness to keep the height of each suction cup consistent. Therefore, under normal circumstances, do not disassemble the suction cup. If the suction cup glue is damaged, it should be replaced with the same thickness. (2) after using the vacuum pump for a period of time, the vacuum degree will drop due to water inflow and other reasons (That is, the suction drops) Phenomenon, so pay attention to check and eliminate the fault, otherwise, the machine works under the condition of insufficient suction, on the one hand, it will affect the grinding quality, on the other hand, it is also prone to safety accidents. 3. Whether the cooling is sufficient also has a great influence on the grinding effect. Always check the cooling pipe for blockage. In particular, the pipeline of the linear edging machine is easy to be blocked by bristles, and it is not easy to be detected after blocking, which will cause insufficient cooling and affect the edging quality. 4. The quality of the grinding head of the edging machine has a great influence on the grinding quality of the glass. The position of the grinding head and the moving gap have been adjusted when leaving the factory. In addition to the advance and retreat grinding head, do not move the rest, so as not to affect the grinding quality. In addition, the back position of the grinding head is not easy to be too large, otherwise it is easy to damage the waterproof sleeve, causing water leakage, and it is easy to burn the motor. This is some popularization of the correct and standardized use of glass edge grinding machines.

Māori pēpī in research gap
A Liggins Institute study has found the most pressing research questions around mother and baby healthcare relate to improving outcomes for Māori and Pacific whanau.
Lead researcher Katie Groom says the study was done for ON TRACK, the national clinical trials network, to identify gaps in current knowledge of pregnancy and newborn care.
The top 20 priorities all related directly to Māori and Pacific health.
Associate Professor Groom says research topics needed to be suitable for clinical trials or large observational studies.
She says there's currently a cookie-cutter model of pregnancy care where everyone gets a similar approach, whereas Māori pregnancy outcomes could be improved by the care that includes their whānau and iwi.
Research is also needed to understand enablers and barriers to training Māori doctors and midwives, and whether current training models work for Māori.

The finite-difference time-domain (FDTD) method is a commonly used electromagnetic simulation method. However, in the analysis of electrically large structures with curved boundaries, the FDTD method suffers from cumulative errors introduced by inadequate resolution of curvature (stair-casing errors), reflection from absorbing boundaries, numerical dispersion, etc. On the other hand, integral equation based methods such as the method of moments (MoM) have available a wide variety of shape functions and grids for accurate resolution of the field on curved boundaries. In this paper, we propose to hybridize the FDTD method and the MoM such that FDTD can be implemented on a relatively crude mesh, and the resulting 'crude' solution employed as an initial guess to the solution of the MoM matrix equations using the conjugate gradient (CG) method.

Bhargav Gajjar contrives drones with perching legs for improved spying
Military drones generally tend to be stealthy in their design, but at the same time they are also meant to be bad-ass in their features. Well, Bhargav Gajjar of Massachusetts based Vishwa Robotics, does envision a military drone that conforms to the later consideration in quite an innovative manner. As a result, he specializes in creating add-ons like legs for bantam US air force drones. These 'legs' are normally utilized as advanced landing gear by the tiny machines, which is in stark contrast to the prevalent crude practice of crash landing or hard landing of drones. However beyond just practicality, there is an elegant side to this ingenious scope. The precision landing mechanism mimics the posture of a perching predatory bird, thus bringing that bad-ass essence into the mix.
For his commercial project, Gajjar had to study a number of different bird species and then record their landing with the help of a high-speed camera. Finally, he settled on the landing ambit exhibited by American kestrel, a smaller variant of falcon. Similar to kestrel's natural scope, the drone's perching legs can also perform the action of waddling, which comes in handy during indoor missions.
But the greatest advantage of a drone equipped with Gajjar's invention is its enhanced gripping action derived out of an electric motor. Additionally, the grip is much stronger because of the sharpness exhibited by the perched legs. This also allows the drone to be more stealthy, as now the robot can easily choose a perfect vantage point for effective snooping sessions.

Understanding Pages and Extents
The fundamental unit of data storage in SQL Server is the page. The disk space allocated to a data file (.mdf or.ndf) in a database is logically divided into pages numbered contiguously from 0 to n. Disk I/O operations are performed at the page level. That is, SQL Server reads or writes whole data pages.
Extents are a collection of eight physically contiguous pages and are used to efficiently manage the pages. All pages are stored in extents.
In SQL Server, the page size is 8 KB. This means SQL Server databases have 128 pages per megabyte. Each page begins with a 96-byte header that is used to store system information about the page. This information includes the page number, page type, the amount of free space on the page, and the allocation unit ID of the object that owns the page.
The following table shows the page types used in the data files of a SQL Server database.
Data rows with all data, except text, ntext, image, nvarchar(max), varchar(max), varbinary(max), and xml data, when text in row is set to ON.
Large object data types:
Variable length columns when the data row exceeds 8 KB:
Global Allocation Map, Shared Global Allocation Map
Information about whether extents are allocated.
Page Free Space
Information about page allocation and free space available on pages.
Index Allocation Map
Information about extents used by a table or index per allocation unit.
Bulk Changed Map
Information about extents modified by bulk operations since the last BACKUP LOG statement per allocation unit.
Differential Changed Map
Information about extents that have changed since the last BACKUP DATABASE statement per allocation unit.
Log files do not contain pages; they contain a series of log records.
Data rows are put on the page serially, starting immediately after the header. A row offset table starts at the end of the page, and each row offset table contains one entry for each row on the page. Each entry records how far the first byte of the row is from the start of the page. The entries in the row offset table are in reverse sequence from the sequence of the rows on the page.
Large Row Support
Rows cannot span pages, however portions of the row may be moved off the row's page so that the row can actually be very large. The maximum amount of data and overhead that is contained in a single row on a page is 8,060 bytes (8 KB). However, this does not include the data stored in the Text/Image page type. This restriction is relaxed for tables that contain varchar, nvarchar, varbinary, or sql_variant columns. When the total row size of all fixed and variable columns in a table exceeds the 8,060 byte limitation, SQL Server dynamically moves one or more variable length columns to pages in the ROW_OVERFLOW_DATA allocation unit, starting with the column with the largest width. This is done whenever an insert or update operation increases the total size of the row beyond the 8060 byte limit. When a column is moved to a page in the ROW_OVERFLOW_DATA allocation unit, a 24-byte pointer on the original page in the IN_ROW_DATA allocation unit is maintained. If a subsequent operation reduces the row size, SQL Server dynamically moves the columns back to the original data page. For more information, see Row-Overflow Data Exceeding 8 KB.
Extents are the basic unit in which space is managed. An extent is eight physically contiguous pages, or 64 KB. This means SQL Server databases have 16 extents per megabyte.
To make its space allocation efficient, SQL Server does not allocate whole extents to tables with small amounts of data. SQL Server has two types of extents:
Uniform extents are owned by a single object; all eight pages in the extent can only be used by the owning object.
Mixed extents are shared by up to eight objects. Each of the eight pages in the extent can be owned by a different object.
A new table or index is generally allocated pages from mixed extents. When the table or index grows to the point that it has eight pages, it then switches to use uniform extents for subsequent allocations. If you create an index on an existing table that has enough rows to generate eight pages in the index, all allocations to the index are in uniform extents.


Kia Optima Hybrid: Air Conditioning System / Compressor Oil Repair procedures
Oil Specification
1.
The HFC-134a system requires synthetic (POE) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed.
2.
Compressor (POE) oil varies according to compressor model. Be sure to use oil specified for the model of compressor.
Since the electric compressor uses high-voltage, you should use POE oil which have high Volumetric Resistivity.
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.

If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.
If the POE oil gets mixed with PAG oil, replace the compressor with new one and clean inside the A/C system (condenser, refrigerant line, evaporator and etc.)
Handling of Oil
1.
The oil should be free from moisture, dust, metal powder, etc.
2.
Do not mix with other oil.
3.
The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC-134a Compressor Oil absorbs moisture very easily.)
4.
The compressor oil must be stored in steel containers, not in plastic containers.
Compressor Oil Check
The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the original amount of oil.
Oil total volume in system
POE OIL : 3.8 ~ 4.5 oz. (115 ~ 135cc)
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculation with the refrigerant in the system. When checking the amount of oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return operation. The procedure is as follows:
1.
Open all the doors and the engine hood.
2.
Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.
3.
Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4.
Stop the engine.

Marmoset Twins are Born
Here are new arrivals at the Zoo in Belfast. Two Monkeys at the same time, yes twins have arrived and they are Pygmy Marmosets which are the smallest Monkeys in the world!! So cute. The twins are carried by their parents most of the time, but they're becoming more adventurous by the day.
Pygmy Marmosets are one of the world's smallest primates, with adults weighing four to five ounces (110-140g) when fully grown. Native to South America's upper Amazon basin, Pygmy Marmosets dwell in rain forests and feed primarily on tree gum. Using specialized teeth, Marmosets gnaw on trees until sap is released, then lick up the sap. They also feed on insects which are attracted to the sap, as well as fruits and nectar.

I am trying to prove the following algorithm to see if a there exists a path from u to v in a graph G = (V,E).
I know that to finish up the proof, I need to prove termination, the invariants, and correctness but I have no idea how. I think I need to use induction on the while loop but I am not exactly sure how.
How do I prove those three characteristics about an algorithm?

Disclaimer: I don't know how much formal you want your proof to be and I'm not familiar with formal proofs.
 1. induction on the while loop: Is it true at the beginning? Does it remain true after a step (quite simple path property)?
 2. same idea, induction on k (why k+1???): Is it true at the beginning? Does it remain true after a step (quite simple path property)?
 3. Think Reach as a strictly increasing set.
Termination: maybe you can use a quite simple property linked to the diameter of the graph?
(This question could probably be better answered elsewhere, on _URL_ maybe?)
share|improve this answer
There is a lot of possibilities. For example, for a Breadth First Search, we note that: (1) The algorithm never visits the same node twice.(as any path back must be >= the length that put it in the discovered pile already. (2) At every step, it adds exactly one node.
Thus, it clearly must terminate on any finite graph, as the set of nodes which are discoverable cannot be larger than the set of nodes which are in the graph.
Finally, since, give a start node, it will only terminate when it has reached every node which is connected by any path to the start node, it will always find a path between the start and target if it exists.
You can rewrite these logical steps above in deeper rigour if you like, for example, by showing that the list of visited nodes is strictly increasing, and non convergent (i.e. adding one to something repeatedly tends to infinity) and the termination condition must be met at at most some finite value, and a non convergent increasing function always intersects a given bound exactly once.
BFS is an easy example because it has such simple logic, but proving these things for a given algorithm may be extremely tricky.

Mothman - Alien from another world, or a being from the spiritual realm
More than a film or the 12 foot tall, stainless steel sculpture on display in downtown Point Pleasant in West Virginia, Mothman is a strange creature seen in the United States between November 1966 and November 1967, appearing several times in West Virginia, on the border with Ohio. Artist Robert Roach portrayed the creature in his sculpture as people reported the sightings, a man-sized beast with wings and large reflective or luminous red eyes, that scientist tried to associated with owls, but due to the size and characteristics, it is believed that Mothman was a paranormal phenomena, mostly see during the 1966-69 years.
However, some theories associate Mothman with visitors from outer space or a type of Alien never seen before or after his visit. Mothman was first sighted in November 12, 1966, and named after the Batman TV series. The first apparition occurred in a cemetery close to Clendenin, West Virginia while a group of 5 men were preparing a grave. The workers described the being as a "brown human shape with wings" which lifted off from behind nearby trees and flew over their heads. This sighting was kept in secret in the belief it would not occur again, but 3 days later two young married couples from Point Pleasant, were out for a drive and saw two red lights in the shadows of a nearby World War II TNT factory.
After stopping the car, their curiosity led them to see that the lights were the glowing red eyes of a large animal described as "shaped like a man, but bigger, maybe six and a half or seven feet tall, with big wings folded against its back". This time the creature started chasing the couples, who were terrified drove off in their car, heading for Route 62 toward the Mason County courthouse after finding the creature again standing on a ridge near the road. Later it was revealed that a poltergeist attacked one of the couples' home later the same night, after the encounter with Mothman.
Apparitions of Mothman continued in West Virginia during all of November 1966, and after the reports, strangers dressed in black began to appear in the area. Nobody knew who the Mothman, or the men in black were and where they had come from or went, one year later. Some neighbors of West Virginia believe that Mothman was an alien and the men in black were government agents investigating the strange occurrences, but most people are convinced that Mothman was a paranormal being and the mysterious visitors were Catholic priests who went to exorcise the demonic creature.

The aim of this School Based Assessment is to investigate unemployment in the community of Block 2E Garvey Meade, Portmore and to give or suggest recommendations that can be put in place to improve the unemployment rate in the community
Methodology EMPLOYED
In order to carry out this research the researcher will be using printed questionnaires. A questionnaire is an inexpensive way to gather data from a potentially large number of respondents, it is a series of questions written or typed and given to individuals to obtain statistically useful information about a given topic. Questionnaires were used because of its advantage to gather numerous information from different persons in a short time span, when compared to doing multiple interviews. The researcher also gathered information from other sources such as the internet and books. This was done so that the information presented was as close to a hundred percent accurate as possible.
The researcher of this assignment wanted to know the main cause and effect of unemployment in his community and how it impacts the community and its members. The researcher structured a set of five questions to aid in his effort, these are: What are the effects of unemployment?
How are the unemployed surviving?
What are some benefits of unemployment?
* What is the main reason for unemployment?
* What can be done to reduce unemployment?
The researcher collected the information presented in this S.B.A from the community of Block 2E Garvey Meade in Portmore, St. Catherine which holds approximately twenty-five households. A total of fifteen questionnaires were prepared for distribution, as the researcher thought that it was necessary to obtain answers from at least fifty percent of the inhabitants of the community. The researcher had expected for ten questionnaires to return.
The researcher wanted to ensure as much accuracy as possible...

April 19, 2006 - Refuge fire crew assists Stillwater NWR with emergency prescribed burn
Heavy rains and increasing snow melt resulted in pressure for quick measures to move large quantities of water through Stillwater National Wildlife Refuge. The refuge has a series of canals designed to facilitate just such an effort, however a major section was thickly overgrown with tule reeds and posed a risk of clogging and potential flooding. A crew from Klamath Basin traveled to Fallon, NV, and burned nearly 10 miles of canals, significantly reducing the thick vegetation and increasing flow ability. Weather and holding conditions permitted the crew only two days of burning before new rains inundated roads and limited access. Refuge managers report the burns increased their ability to safely deliver water through the refuge.
See pictures from the burn on the Stillwater NWR Stills page.

Types of Aerospace Insulation Materials
Aircraft insulation materials are used throughout the interior of most airplanes to reduce noise levels and protect passengers from excessive temperatures. Aerospace Insulation Materials are typically made from an insulator surrounded by an aircraft-rated plastic covering to hold the material in place and prevent moisture from entering the aircraft. Aerospace insulators also include flame retardant properties to minimize the risk of fire and aid in reducing the spread of a fire once it has ignited.
Depending on the aircraft type, aerospace insulation needs can vary greatly. For example, engine nacelles or encasements require thermal insulation to maintain consistent internal operating temperatures and avoid heat loss that can damage the inner workings of the aircraft and outer casing. Flexible microporus insulation is an effective choice to meet these requirements. It can be molded into tight spaces to provide a custom fit while still meeting all required temperature, weight and performance specifications.
Mica insulation is another option to consider for aerospace applications. It's a lightweight, flame retardant material that can be manufactured into a variety of shapes for various aircraft applications. For example, mica roll laminates can be used to insulate ducting and tubing. It can also be used to manufacture insulation pads, curtains and expansion joints. Mica is ideal for aircraft insulation because of its high temperature resistance and ability to withstand harsh environments.
Thermocouple insulators, light-duty stand-off insulators, heavy-duty stand-off insulators and suspender insulators are other types of insulators that can be used in the Aerospace industry. These insulators are often made from ceramic and composite materials that have an abrasion, chemical, corrosion and moisture resistant coating. They are typically made of alumina, zirconia, mullite, cordierite or steatite and can be provided in cylindrical, conical or flat forms.
Most Aerospace insulation materials must have flame-retardant properties to reduce the risk of in-flight fires and assist in preventing or delaying post-crash fuel fires from igniting in the fuselage. These insulators are also able to withstand the rigors of an aircraft's harsh environments and safeguard critical electronics.
In addition to insulating against temperatures and sound, aviation insulation is also required to prevent the transmission of unwanted vibrations throughout the aircraft's structure. This is essential to ensuring passenger comfort, as well as limiting the damage that can be caused by vibrations on aircraft components and structural parts.
Aerospace tapes are designed to make composite molding easier to handle and boost bonding, sealing and insulation performance. They are available in a variety of thicknesses, widths and colors to match the specific requirements of any aircraft. They're designed to provide an ideal surface for composite bonding, protect against fluids, improve handling and speed up installation times. They're also abrasion and corrosion resistant and can be supplied with an anti-stick coating to ensure clean removal from the surface of the aircraft.


Introduction to date-fns – a Lightweight JavaScript Date Library
Introduction to date-fns
Working with dates in JavaScript is a pain. Native date methods are often verbose and occasionally inconsistent — something which also makes them error-prone. But good news is at hand. There are several libraries that exist to take the pain out of date manipulation. These libraries are to JavaScript dates, what jQuery is to the native DOM API.
Let me give you an example. This is the accepted answer to a Stack Overflow question asking how to get last day of the month:
var t = new Date();
alert( new Date(t.getFullYear(), t.getMonth() + 1, 0, 23, 59, 59) );
Watch Learn JavaScript Syntax and Programming Principles
Power your JavaScript code. Power the modern web.
Of course that works, but it's not immediately obvious what the numbers after getMonth represent. Now contrast that with the considerably more readable:
const today = new Date();
console.log( lastDayOfMonth(today) );
That lastDayOfMonth method is one provided by date-fns, a self-proclaimed comprehensive toolset for manipulating JavaScript dates in the browser and Node.js.
In this article I'm going to show you how to get up and running with date-fns. After reading you'll be able to drop it into your projects and take advantage of its many helper methods to manipulate dates with ease. This will make code like t.getMonth() + 1, 0, 23, 59, 59 a thing of the past.
So, Why Not Just Use Moment.js?
The elephant in the room is Moment.js. This library has undoubtedly become the de-facto standard for working with dates in JavaScript. So why not use that? Why do we need another JavaScript date library?
Well, according to Sasha Koss, the creator of date-fns, Moment.js has a few inherent problems which motivated him to create date-fns. Sasha expands on what these problems are on the project's GitHub page, but in a nutshell:
 - Moment.js is mutable which can cause bugs.
 - It has a complex OOP API (which doubles the mutability problem).
 - It has a performance overhead due to the complex API.
 - Its build size is large when used with Webpack, as locale files are included as part of the bundle.
Let's contrast that with date-fns (taken from the project's homepage):
 - Date-fns is immutable, always returning a new date instead of changing the one you pass in.
 - It has a simple API. You always have one function that does one thing.
 - It is fast. You can be sure that your users will have the best user experience.
 - It is the perfect companion for Webpack. With the function-per-file style you can pick just what you need and stop bloating your project with useless functionality.
For me, the feature that makes it shine is its ease of use. When using it on a web-based project, you can just grab date-fns from a CDN, drop it into your page and profit. More about that next…
Installation
There are a variety of ways to install the library.
It's available as an npm package:
npm install date-fns --save
Or via Yarn:
yarn add date-fns
Or Bower:
bower install date-fns
Or from a CDN:
<script src="_URL_
If you chose this method, please note that the library is namespaced under a dateFns object, in the same way that jQuery is namespaced under $.
<script>
 console.log(
 dateFns.isToday(new Date())
 );
</script>
Date-fns Basic Usage
Assuming you're using a module loader you can require only those parts you need. The following example shows you how to format a date.
const format = require('date-fns/format');
console.log(
 format(new Date(2017, 6, 6), 'MM/DD/YYYY')
);
// '06/07/2017'
Want to change the locale? No problem:
const format = require('date-fns/format');
const deLocale = require('date-fns/locale/de') // German
console.log(
 format(new Date(2017, 6, 6), 'DD MMMM YYYY', { locale: deLocale })
);
// 06 Juli 2017
Here's a list of supported languages.
If you're working in the browser, don't forget to hang any calls to helper methods off of a dateFns object. Here's how to determine the last day of the month using the aptly named lastDayOfMonth method:
<script src="_URL_
<script>
 console.log(
 dateFns.lastDayOfMonth( new Date(2017, 6, 7) )
 );
 // Mon Jul 31 2017 00:00:00 GMT+0200 (CEST)
</script>
Note that date-fns has equivalent methods for determining the last day of the week, quarter and year.
Immutability, Pureness and Simplicity
One of the selling points for date-fns is that its functions are pure, and simple, to explain. This leads to easy to understand code, which is easier to debug when things go wrong.
Let me demonstrate this using Moment.js as a counter example. As mentioned before, dates in Moment are mutable, which can lead to unexpected behavior.
const moment = require('moment');
const now = new Date();
const mNow = moment(now);
mNow.add('day', 3);
console.log(mNow.toDate());
mNow.add(3, 'day');
console.log(mNow.toDate());
// 2017-07-08T22:00:00.000Z
// 2017-07-11T22:00:00.000Z
There are a couple of things to take note of here. Moment's add function is not fussy about the order in which it accepts its arguments (although the first method will now throw a deprecation warning). But more confusing is that if you call add multiple times in a row you, won't get the same result because Moment objects are mutable:
mNow.add(3, 'day'); // add 3 days
mNow.add(3, 'day'); // adds 3 **more** days
Now compare that to date-fns which keeps arguments in one order and always returns the same result, returning a new Date object for each call.
let addDays = required('date-fns/add_days');
addDays(now, 3); // (April 30, 2017)
addDays(now, 3); // (April 30, 2017)
addDays(now, 3); // (April 30, 2017)
Also notice how the method name is more expressive (addDays instead of just add), keeping things consistent and having one method to do one thing and one thing only.
Comparing Dates
If you look at the list of posts on SitePoint's JavaScript channel, you can see that some are listed as being published on a certain date, whereas others are listed as being published X days ago. It might take a while if you tried to implement this in vanilla JavaScript, but with date-fns this is a breeze – just use the distanceInWords method.
Let's compare two different dates.
const distanceInWords = require('date-fns/distanceInWords');
const startDate = new Date(2017, 3, 27); // (April 27, 2017)
const endDate = new Date(2018, 3, 27); // (April 27, 2018)
console.log(
 distanceInWords(startDate, endDate)
);
// "about 1 year"
In date-fns if you want to know the difference in another unit, you can substitute any of the following:
 - Milliseconds
 - Seconds
 - Minutes
 - Hours
 - Days
 - Months
 - Years
Where the method names are differenceIn[any of the above here] like differenceInDays.
Working With Collections of Dates
Date-fns has some very handy helper methods which you can use to manipulate collections of dates in all kinds of ways.
Ordering a Collection of Dates
The following example uses compareAsc to sort dates into ascending order. To do this, it returns 1 if the first date is after the second, -1 if the first date is before the second or 0 if dates are equal.
const compareAsc = require('date-fns/compare_asc');
const date1 = new Date('2005-01-01');
const date2 = new Date('2010-01-01');
const date3 = new Date('2015-01-01');
const arr = [date3

"Chariots and Other Wheeled Vehicles in Italy before the Roman Empire" presents evidence for transport by wheeled vehicle in Italy before the Roman Imperial period, the beginning of which is often thought to be marked by Augustuss conquest of Egypt in 30 BC. The study begins with a glossary of technical terms and with evidence for roads and the animals that were used in draught. The major part is concerned with the vehicles themselves - two-wheeled chariots and carts and four-wheeled wagons - their construction, the ways in which their draught animals were harnessed and controlled, and the uses to which the equipages were put. A wide range of evidence is drawn upon including figured documents such as architectural terracottas, stone reliefs, vaseand wall paintings; bronze and terracotta models and the remains of actual vehicles, in a few cases accompanied by their harness teams recovered from tombs, primarily from central and northern Italy of the eighth and seventh centuries BC onwards. The concluding chapter looks at the history of wheeled vehicles in Italy before the Roman Imperial period. It traces local, Italic characteristics and possible foreign influences, and assesses the relative economic and social importance of the different kinds of wheeled vehicles and of other means of land transport - by pack and riding animals. In appendices the vehicles depicted in so-called Situla Art and the 'Celtic chariot' are discussed. Lavishly illustrated with over 170 plates and figures, this book is important for the history of transport, technology and draught.

While the invoice is Not Paid, then some follow up actions can not happen. When it transitions to Paid you want those actions to happen. But if you peek you don't want to see a Not Paid invoice and those actions having occurred.
What you are looking for here is a transaction. Use your database engine to ensure the invoice is either paid, or not paid. If your application is restarted it will always load that invoice in one state or the other.
Unfortunately you will still need to manage side-effects such as: changes to files, internal state, or events for external services.
Side-effects and State
If you need to update other information not in the database you will need to manage your own roll-forward, and roll-back behaviours.
A good way to encapsulate this is with a Task Queue, and Workflows.
When the invoice commits, also commit a task object to a queue. Have that queue polled regularly (or even signal it post-commit) to pick up the next task. This task performs the next action in the workflow.
 - If it succeeds it removes itself from the queue and adds any further tasks.
 - If it fails you have several choices:
 - try again, cleaning up on the retry.
 - undo, and stop
 - undo, and create an undo task for the workflow this far.
 - undo, and continue
This style has the benefit of forcing you to think through all the possible states of the system, and how to move through them.
Eventing
Eventing causes side-effects. These usually cannot easily be undone, though there are exceptions, so generally they are sent only after your application is in the new state. In the case of the invoice, this is after the transaction commits.
You can use the task abstraction above to attempt to deliver events in a push manner. Either as a once off attempt, or repeated some number of times. There is no guarantee that this event will be received (or possibly even sent). So relying on a purely push approach will fail. This also implies that any task which creates an event should not rely on the event having been received.
As pushing events may fail, the only other solution is to support polling. For this to work you will need to log each event that needs to be communicated with some unique id for each event. This is called event sourcing.
You can implement a purely polling strategy, but this is inefficient. A hybrid push/pull approach is usually best. Poll infrequently, and attempt to push only a limited number of times. If the receiver misses any event it can detect this on the next poll/received push.

Research - Foodways Research: A Taste of Maine
The study of foodways enhances our understanding of how individuals sustain membership in ethnic and regional groups. The relationship between food and group assist in interpreting group identity. The foods that people eat are often used to describe "others" who eat differently from the mainstream group. Most ethnic and regional groups are most usefully defined internally, using the groups' markers of self-identification. And it is clear that region and ethnicity are intertwined. In the United States, a region often exhibits a culinary hybridity. For example, in New England, Native American cuisine (corn, beans, squash) is blended with European cuisine (wheat) mostly from England but with touches of Africa (sugar cane, molasses). And as we move forward historically, other immigrant groups have added their traditional foods and spices to the mix.
The Maine Folklife Center has embarked on a project to document Maine traditional foods. A delicious story unfolds, from the blueberry fields of Downeast and the fisheries of coastal Maine, to the potato fields of Aroostook County and the bean-hole beans of lumber camps. These food traditions have increasingly moved into community settings everywhere, including urban settings around the state, where established and newer immigrants are adapting their food traditions in ways that Mainers have been doing since Europeans first arrived and began eating, hunting, and farming alongside Native peoples.
Drawing on the wealth of foodways in the state, "A Taste of Maine" explores how the family story, community history, and significant events of national history are regularly expressed through food, and teach larger lessons about geography, history, art, and culture, as well as lessons regarding tradition and change.
Beginning with beans.
In the beginning, there were beans. Traditional Native American cuisine consisted of corn, beans and squash. These three foods play a vital role in defining modern American cuisine. We find grits, cornbread, and red beans and rice in the south, tortillas and pinto beans in the Southwest, baked beans and succotash in the Northeast, and pumpkin pie across the continent. English settlers in the northeast brought a culinary tradition with them that was then blended with local foods such as turkey, maple syrup, lobster, clams, cranberries, corn and beans to provide Indian pudding, Boston baked beans and brown bread, clam chowder and boiled lobster.
Maine Native people today still make a traditional bean and corn dish known as hull corn soup. Corn which has been soaked in ashes and water and had the skin removed is added to yellow-eye beans and sometimes bits of meat. Water is added and the mixture is cooked into a hearty soup. In years gone by, Natives also baked beans with maple syrup and bear fat in ceramic pots in the ground. Englanders adapted their own versions of the corn soup (succotash) and the baked beans.
Across New England, and certainly throughout Maine, a tradition of baked bean suppers takes place in community institutions such as churches, granges, and firehouses. The tradition of baked beans for Saturday night supper seems to have originated with the pilgrims, who would cook enough so that they would not have to cook on the Sabbath. The eating of beans extends to Sunday morning as well, and many Mainers speak of eating beans for Sunday morning breakfast. Today, bean suppers are often used as fundraisers. For example, the Caribou Lions Club holds three or four bean-hole bean suppers annually to raise money for their service organization.
While Boston is known as bean-town, only in Maine can you ever really get to know beans. B&M (Burnham and Morrill) baked beans of Portland still bakes beans in huge iron pots in brick ovens before they can them for distribution around the country. The Kennebec Bean Company in North Vassalboro packages a range of Maine-grown beans under the "State of Maine" label and also sells many of them prepared to an old Maine lumber camp formula. They cook varieties of beans only known in Maine. There are other, smaller canning companies who can traditional Maine beans as well.
Boston baked beans are usually made from the white navy or pea bean, a small, thin-skinned and fairly tasteless variety. However, in Maine there are numerous varieties that are local favorites. While yellow-eye beans are the most popular Maine bean, others are preferred in some areas of the state. Pauleena MacDougall recently interviewed bean grower Patricia Qua who provided substantial insight into Maine's traditional beans.
There are little pockets [of people who want a certain type of bean]. I tried selling yellow-eye beans to a restaurant in Lewiston -a chain I sold to 4 other restaurants. In Lewiston they wanted the pea beans (Navy beans) the small white variety. I don't grow those. I have a little sales route that goes down through NH, I noticed west of Fryeburg and North Conway they're a lot more interested in Jacob's Cattle. And Downeast, there is a small brown bean. Northeast of Ellsworth is a real center for Marifax beans. Something I heard was brought in during the depression. And yellow eyes, you almost can't give them away there in that part of the state. They love the Marifax-I'm not sure they use any sweetener; they cook them with salt and pepper and salt pork. They cook them for a long time. Also, I noticed some years Soldier bean sales are higher and no one will buy Jacobs Cattle, now this year, Jacob's Cattle are selling very well and I have no idea why.
PM: Do you sell any beans in Aroostook County?
PQ: People come down to get them.
PM: Do you notice any preference?
PQ: Yes, yellow eye.
PM: How about King of the Early?
PQ: Yes, they are kind of the same track as Marifax. Downeast.
PM: Do you sell to any of the Maritime Provinces?
PQ: I know people in New Brunswick who grow the yellow eye beans.
PM: And in northern Maine the yellow eyes?
PQ: Yes, and also the soldier beans.
PM: What about kidney beans, does anybody buy those?
PQ: Yes, people like to make chili. But the yellow eyes probably 75-80% of my sales, then Soldier Beans, Jacob Cattle and then the kidney beans.
PM: [pointing to some beans in her shop] Are these soy beans?
PQ: No, they are the sulfur beans, they are supposedly from the Brewer area, originally. They cook up like a yellow eye but a little bit sweet. [also called China yellow].
PM: Wow, you're just a wealth of information about beans! (both laugh).
PQ: Oh, and the Bumblebee beans, these come from Garland, actually. A lady from Rowe's orchard used to grow these. I think they are a local heirloom type bean. They swell up very large. All I can think of is the giant beanstalk…
There are umpteen varieties of yellow-eye beans -these are some I saved from a lot of different batches which have a lot of the molasses coloring-almost half the bean is gold. These took seven years to save out of my grading. A lot of the specialty shops like these because they are so colorful. Now there was a Maine yellow eye that has a very small eye. It has a lot more white. Most people now have gone to growing the Ken Early yellow eyes, which have a little more color with a week and a half shorter growing season, and they are shorter. It's hard to harvest beans that grow high and fall over. But there is another bean they grow out in the mid-west which is Steuben yellow eye which is half white and half molasses color. They don't have the same texture or they don't taste the same to me. And I wonder if there is something in the soil that makes our Maine beans taste better. I'm not sure.
Yellow eye bean: The most popular baking bean in Maine comes in several strains including the Steuben, which is one of the oldest of heirloom beans. The Maine Yellow Eye Bean is the baked bean of choice for church and grange suppers, because of its clean, mild taste has wide appeal.
Soldier Bean: According to Patricia Qua, this is the second most popular bean in Maine It is also an heirloom white kidney-shaped bean with a distinctive maroon marking on the eye that resembles an old-fashioned toy soldier. It is closest in flavor to the Maine yellow eye.
Jacob's Cattle is a plump, pure white, kidney-shaped bean with vivid maroon splashes. It is full-flavored, holds its shape under long cooking, and stands up well to plenty of seasoning.
Marifax is a dense, chewy bean with plenty of flavor. Its origins are mysterious but tradition has it that it was introduced by the U.S. government during the Depression to help alleviate poverty. The only place the bean is eaten is in one tiny area along the Maine coast where the only viable crops are blueberries.
Sulphur or China Yellow Bean is a thin-skinned, nearly round Maine heirloom bean that has a tawny yellow color but cooks white and has a distinctly unique flavor.
While many people in Maine cook their beans in a ceramic bean pot, the most unique cooking process for beans in Maine developed in the Maine logging camps. Pork and beans, baked in a bean hole, remains the logger's main dish. The slow, long cooking makes the bean very digestible as well as tender and delicious. In the logging camps, beans were served at every meal. The bean hole is a stone-lined pit in which a fire is built until a good

Publisher's Summary
Prepare yourself to defend the truth against the greatest worldview threat of our generation.
In recent years, a set of ideas rooted in postmodernism and neo-Marxist critical theory have merged into a comprehensive worldview. Labeled "social justice" by its advocates, it has radically redefined the popular understanding of justice. It purports to value equality and diversity and to champion the cause of the oppressed.
Yet far too many Christians have little knowledge of this ideology, and consequently, don't see the danger. Many evangelical leaders confuse ideological social justice with biblical justice. Of course, justice is a deeply biblical idea, but this new ideology is far from biblical.
It is imperative that Christ followers, tasked with blessing their nations, wake up to the danger, and carefully discern the difference between biblical justice and its destructive counterfeit.
This book aims to replace confusion with clarity by holding up the counterfeit worldview and the Biblical worldview side-by-side, showing how significantly they differ in their core presuppositions. It challenges Christians to not merely denounce the false worldview, but offer a better alternative - the incomparable Biblical worldview, which shapes cultures marked by genuine justice, mercy, forgiveness, social harmony, and human dignity.

Electrostatics of polymer translocation events in electrolyte solutions
journal contributionposted on 19.01.2018, 14:10 authored by Sahin Buyukdagli, Tapio Ala-NissilaTapio Ala-Nissila
© 2016 Author(s).We develop an analytical theory that accounts for the image and surface charge interactions between a charged dielectric membrane and a DNA molecule translocating through the membrane. Translocation events through neutral carbon-based membranes are driven by a competition between the repulsive DNA-image-charge interactions and the attractive coupling between the DNA segments on the trans and the cis sides of the membrane. The latter effect is induced by the reduction of the coupling by the dielectric membrane. In strong salt solutions where the repulsive image-charge effects dominate the attractive trans-cis coupling, the DNA molecule encounters a translocation barrier of ∼10 kBT. In dilute electrolytes, the trans-cis coupling takes over image-charge forces and the membrane becomes a metastable attraction point that can trap translocating polymers over long time intervals. This mechanism can be used in translocation experiments in order to control DNA motion by tuning the salt concentration of the solution.

Bálint BalassiArticle Free Pass
Bálint Balassi, Balassi also spelled Balassa (born Oct. 20, 1554, Zólyom, Hung.—died May 30, 1594, Esztergom), the outstanding Hungarian lyric poet of his time, remaining unrivaled in his native literature until the end of the 18th century.
Balassi was born into one of the richest Protestant families of the country and lived an adventurous life, fighting against the Turks and against his own relatives, who sought to despoil him of his heritage. At first his poetry was conventional, but his powerful personality soon found original expression. He wrote vividly about the beauties of the countryside and the rough pleasures of warfare. His love poems show genuine feeling. Balassi was the inventor of a stanza form that was copied by later poets. His conversion to Roman Catholicism led to a religious poetry in which he exhibited a strong spirituality. He died of wounds received during the siege of Esztergom.

The Movement of the Sun through our Galaxy
Introduction and Purpose
The Visual Basic program VB Galaxy is a copy of the QBasic program: Galaxy.bas The purpose of the program VB Galaxy is to simulate the movement an object (the Sun) through Our Galaxy (The Milky way) with three posibilities:
 1. When the radial speed is rougly 250 km/sec. In this case its path is a circle.
 2. When its radial speed is almost zero. In this case its path is almost a straight line. The object will oscillate.
 3. When its radial speed is almost zero and when there is a black hole in the center of our Galaxy. In this case the path will be bended when the object approaches the BH.
To get a copy select: VB galaxy.zip
To see the listing of the program select: VB.GALAXY.bas.txt
Description and Operation
The program consists of 3 displays:
 1. Main Selection Display
 2. Simulation Display under three possibilities.
 3. Parameter Selection Display
The Main Selection Display is used to select the Simulation Display or the Parameter Selection Display.
In order to select the Simulation Display: Select possibility 1 to 3 and Select S. This will start the simulation under predefined initial conditions.
In order to select the Parameter Selection Display select 0.
From the Parameter Selection Display you can modify the following parameters:
 1. Delta time in ly
 2. V origin (Galaxy)
 3. Phi origin
 4. Display condition
 5. Initial condition
 6. Speed of gravity
 7. Initial distance of object in lightyears
 8. Initial radial speed of object in km/sec
 9. Mass of Black hole in Sun Masses M0
 1. For type 1 the standard value for Delta time in ly is 0.05 light years. If performance is slow you can try 0.1. For higher accuracy use 0.01.
 For type 2 and 3 delta time is 0.0005 light years.
 2. The parameter V origin (Galaxy) defines the speed of our galaxy in km/sec. The standard value is 0. First try 0. Secondly try 1000 km/sec
 3. The parameter Phi origin defines the direction of the speed of our galaxy as a function of our Sun. Valid values are 0, 90, 180, 270 and 360.
 4. The parameter Display condition defines the number of iterations between screen updates. The standard value is 100.
 5. The parameter Initial condition has to values 0, 1 or 2.
 For a value of 0 there is no change in initial condition.
 For a value of 1 the initial position of the Sun is modified.
 For a value of 2 the initial velocity of the Sun is modified.
 6. The parameter Speed of gravity defines the speed of gravity propagation. Standard value is 300000 km/sec.
 7. The parameter Initial distance in ly defines the initial distance of the object in lightyears. Standaard value for type 1 is 25000 ly and for type 2 and 3 50000 ly
 8. The parameter Initial radial speed of stardefines the initial radial speed of object in km/sec. Standaard value for type 2 and 3 is 0.0015 km/sec
 9. The parameter Mass Black hole in M0defines the Mass of Black hole in Sun Masses M0. Standaard value for type 3 is _PHONE_ Sun Masses M0
The Simulation Display Consists of three parts:
 1. The top part shows the values of the parameters.
 For type 2 at closest distance the simulation stops. Enter any character to continue.
 2. The middle part shows (1) the position and direction of our Galaxy and (2) the position of the Sun in red.
 For the type 2 also in yellow (larger) and braun (largest)
 3. The bottom part shows the values of certain parameters after each revolution of the Sun. The first parameter shows the time in counts accumulated and the time in count between revolutions. The last parameter is important in order to see if the revolution times increases The last parameter shows the distance between the center of the Galaxy and the Sun.
Test Results
All tests are done with delta time = 0.01 light year
Test 1
For V origin = 0 Revolution time is 189.56 million years
Test 2
For V origin = 1000 c = 0 km/sec Revolution time is 189.56 million years
Test 3
For V origin = 1000 c = 300000 km/sec
The table below shows the results of 12 simulations.
The parameter phi defines the direction of the speed of the galaxy.
 init = 0 init = 1 init = 2
phi rev time distance rev time distance rev time distance
 0 191.47 25000.0 189.56 24916.7 189.57 25000.0
 90 189.46 25000.0 189.56 25000.1 189.46 25000.0
180 187.68 25000.0 189.56 25083.3 189.57 25000.0
270 189.67 25000.0 189.56 25000.2 189.67 25000.0
The column init = 0 shows the time in million years after one revolution and the distance in light years, for different values phi. Phi is the direction of the speed of the galaxy.
What the simulation shows is that the revolution time is different i.e. is a function of phi. This is wrong because the Sun moves in a circle and it should not make any difference where you start the simulation.
For phi = 0 the center of galaxy moves towards the Sun. That means the virtual position is away from the Sun. This in turn means that the acceleration is smaller then it should be. Finally this means that the revolution time will be larger.
For phi = 180 the center of galaxy moves away from the Sun. That means the virtual position is toward the Sun. This in turn means that the acceleration is larger then it should be. Finally this means that the revolution time will be smaller.
To solve this problem we can do two things:
 1. change the initial position. This is done in the column init = 1
 2. change the initial velocity. This is done in the column init = 2
The result of both is that the revolution time is almost the same and is independent of the direction of the speed of the galaxy.
Reflection
 1. The simulation assumes that the center of gravity of the galaxy coincides with the center of the Galaxy. This is not correct. The center of gravity of the galaxy, from the point of vew of the Sun, does not coincide with the center of our Galaxy and has an offset towards the Sun. See program MASS_GAL.BAS for details.
 2. Change the speed of gravity with a factor of 100. The revolution time and the distance will be constant.
 3. Does this galaxy simulation requires dark matter ?

Cheque cashing businesses cash third party cheques immediately, so long as adequate personal identification is provided. They usually charge a flat fee plus a percentage of the face value of the cheque. For example, the charge for cashing a $500 cheque may range between $15 and $20. By contrast, all of the major banks provide low-cost bank accounts with monthly fees of under $4.00.
A 2006 survey indicated that seven per cent of Canadians had used a cheque cashing service over the past year. In Ontario, this would amount to over 800,000 users of these services. Low-income Canadians are disproportionately likely to use cheque cashing services, despite the fact that the fees may have a significant impact on take home pay, reducing the amount of money available for basic necessities. This is of particular concern for persons who are on fixed income, such as those receiving government benefits.
Consumers may use cheque cashing businesses, despite the relatively high fees, for a number of reasons. Some Canadians do not have bank accounts. Some may need the cash immediately, and so have concerns about the holds that banks may place on cheques. Lack of convenient bank locations may also be a factor, particularly in remote or low-income areas. Consumers may also use cheque cashing businesses because of convenience, or the quality of the service.
Several Canadian jurisdictions have taken steps to ensure that consumers are able to receive government payments without the high fees associated with cheque cashing businesses. The federal government has entered into indemnity agreements with the banks so that financial institutions that cash federal government cheques can be assured of payment, and at the same time has required the banks to cash federal government cheques for amounts under $1500 without charge. The province of Alberta has moved towards mandatory direct deposit for government benefits, thus obviating the need for cheque cashing. The provinces of Manitoba and British Columbia have passed legislation that enables them to set maximum fees for cashing government cheques.
The Law Commission of Ontario has initiated a project on fees for cashing government cheques. The purpose of the project is to:
1) examine whether cheque cashing fees are an issue of concern in Ontario, and
2) consider approaches for addressing any concerns regarding cheque cashing fees.
The LCO has developed a Consultation Paper to identify issues and options, and to provide a focal point for discussion and consultation. All interested parties are invited to provide submissions, by Friday, June 13, 2008. Submissions may be sent by mail, fax, or e-mail.
Based on the LCO's independent research, including the responses to the Consultation Paper, the LCO will issue a Final Report with findings and recommendations in the fall of 2008.

Include non-communicating reefers in your monitoring procedure
With your REFCON reefer container monitoring system connected to the load calculator or terminal planner, the task of collecting data from the non-communicating containers becomes very simple:
- Transfer the basic reefer container information from the load calculator or terminal planner to REFCON, including container ID, location, expected temperature setpoints, etc.
- Transfer a list of all non-communicating containers from the REFCON system to the handheld RDC unit
- Go to the containers and check the listed data with the actual data on the containers
- Accept or change the data in the RDC
- Go back to the REFCON system and load the corrected data into the system, using a cradle or cable connection
You will now have the actual container data available in the REFCON system. You will also have the alarms on your screen, and you will be able to make the same reports and printouts as for the communicating containers.

Water quality surveys
Our citizen scientists have been collecting important water quality data to help us understand where improvements for the River Chess could be made.
In the first year of the project, we created a baseline assessment of water quality in the Chess catchment.
We knew this would help us identify what major issues the River Chess faced and could then decide how to try and tackle them using citizen science to fill in any knowledge gaps.
What water temperatures is the River Chess reaching during summer heatwaves, and are these temperatures likely to be stressful for key species?
Storm tank overflows
How do storm overflow events from Chesham sewage treatment work impact overall water quality of the River Chess?
How are ammonium, turbidity and dissolved oxygen levels impacted by sewer misconnections in urban environments (Chesam, Rickmansworth)?
What is causing an increase in phosphate and nitrate levels in the mid-reaches of the River Chess between Sarratt and Solesbridge Lane?
Where are the worst problem areas for siltation of sediment in the River Chess, and where is the sediment coming from?
