Call centres represent some of the busiest and most acoustically challenging work environments, with operators managing multiple high-volume calls throughout the day. Ensuring that these spaces offer both comfort and effective noise management is paramount in maintaining employee well-being, productivity and overall job satisfaction. In this in-depth guide, we will explore the essential elements of soundproofing for call centre environments, as well as the innovative acoustic solutions that can transform the workplace into a harmonious and productive space.
To achieve a comfortable acoustic setting within a busy call centre environment, the focus must be placed on balancing essential factors such as noise reduction, privacy management and employee comfort. In addressing these challenges, businesses are poised to improve call quality, ensure clear communication and foster a healthy working atmosphere for their employees. In this article, we will outline a range of crucial considerations, techniques and best practices for designing and implementing effective soundproofing strategies within call centre environments.
Our discussion will shed light on the vital role of sound-absorbing materials and surfaces, as well as the importance of strategic space planning for accommodating the unique acoustic challenges faced by call centres. Moreover, we will delve into the benefits of integrating custom acoustic solutions to support employee well-being, while presenting a strong business case for engaging with acoustic consultants to ensure tailored and effective approaches. Whether you are a call centre owner, facility manager, architect or designer, this comprehensive guide will provide you with valuable insights and strategies to create an acoustically optimised environment that supports and enhances employee performance and satisfaction.
Sound-Absorbing Materials: Tackling Noise Levels and Reverberation
Incorporating sound-absorbing materials within a call centre environment can effectively reduce overall noise levels and improve employee comfort and focus:
– Wall Treatments: Applying acoustic wall panels or wallpaper to the call centre walls can help absorb sound, reduce noise reflection, and improve the overall acoustic performance of the space. These wall treatments are available in various materials, colours, and designs to match the existing décor.
– Ceiling Solutions: Installing suspended acoustic baffles or ceiling clouds can help to reduce reverberation, absorb excess noise, and contribute to a more comfortable noise level within the space. These solutions can be customised to existing ceiling structures and are available in a wide range of materials and designs.
– Flooring Options: Utilising sound-absorbing flooring solutions, such as carpet tiles or rubber mats, can decrease noise from foot traffic and the movement of chairs or office equipment. Additionally, these flooring options offer durability and can be easily replaced as needed.
Space Planning and Design: Privacy Management and Employee Comfort
Strategic space planning and design are crucial for addressing call centre privacy concerns and fostering employee comfort:
– Workstation Configuration: Arranging workstations with ample space in between can help minimise direct noise interference between call handlers. Consider using side-by-side or staggered arrangements to facilitate communication between team members whilst maintaining some level of privacy.
– Acoustic Screens and Partitions: Integrating acoustic screens or partitions around staff workstations can provide a degree of privacy, absorb additional sound, and reduce cross-talk. These solutions can be customised to fit specific workstation sizes and designs, catering to the workflow and aesthetic preferences of the call centre.
– Breakout and Quiet Areas: Allocating designated spaces for breakout and quiet areas can give employees respite from the busy call floor and a place to relax or focus on individual tasks. Providing comfortable, sound-absorbing furnishings and adjustable lighting in these areas can further enhance their effectiveness.
Technological Solutions and Equipment: Supporting Clear Communication
Adopting suitable technological solutions and equipment can further improve soundproofing strategies within call centres:
– Noise-Cancelling Headsets: Invest in high-quality, noise-cancelling headsets for employees, enabling them to hear callers more clearly while reducing background noise. This investment can enhance call quality, improve productivity and reduce employee stress.
– Sound Masking Systems: Consider implementing sound masking systems to introduce a constant ambient noise, negating the impact of sudden or distracting background sounds. This technology can contribute to employee focus and concentration, enabling them to better handle calls with fewer disruptions.
– Acoustic Treatment for Equipment: Apply sound-absorbing materials to office equipment and machinery, such as air conditioning units, office printers and server racks, reducing the noise produced and further promoting a comfortable call centre environment.
Collaborating with Acoustic Consultants: Achieving Bespoke and Effective Solutions
Partnering with expert acoustic consultants can ensure tailored and effective soundproofing strategies for unique call centre environments:
– Customised Acoustic Assessment: An acoustic consultant can assess your call centre's specific acoustic challenges and develop tailored solutions to achieve the desired balance of noise reduction, privacy, employee comfort, and call quality.

How an SD Card Bootloader solves your problems
Transferring data from one drive to another is worrying. Sometimes you discover not all data transferred successfully. You can use a utility app that allows you to move everything with ease. This app makes sure you transfer everything in one swoop, without fumbling around with cables and cords. The same case applies to your work. You keep replacing the microcontroller's firmware and you have to keep plugging and unplugging cables. To avoid all this, the best solution is to invest in an SD card Bootloader.

How to Use the SD Bootloader
Normally, a programming cable programs a microcontroller, which is tedious if you have little space, or you tend to leave tasks undone. A microcontroller is subject to external forces such as loose cables. A Bootloader in a microcontroller is a unique program, which accepts code from outside sources and rewrites it into an internal memory. When the microcontroller powers up and tries to read the newest code that is in the external resource, the Bootloader program deletes the previous code in the memory and rewrites the current code over it.
You can do a bootloader customization for it to derive new code from serial ports or LAN. AN SD card is wireless and using a bootloader becomes a simple matter of SD card insertion and microcontroller reset. Updating code on a bootloader is instant and has little or no system interruption. This makes SD card bootloaders very instrumental in fixed systems that need updating or checking for errors. If you need to change or update the specifications of your code, the SD Card Bootloader comes in handy.

Key considerations
The bootloader will read the hex or binary file of the main app and rewrite it into the microcontroller's memory. There are a few considerations to keep in mind:

- Allocation of memory
There are obvious benefits to using an SD card bootloader, but not every microcontroller is capable of holding a bootloading program, as it is in itself, an application. This means it doesn't need a set amount of space. This space may stand unavailable later if you use a smaller memory microcontroller, or if your code is large. Make sure you allocate enough memory for the bootloader and code if you plan to merge a bootloader.

- SD Card Port Implementation
An SD bootloader needs extra components added to the hardware to give space for the SD Card bootloader. This obviously means added expenses if the main application does not need the bootloader interface. To make sure the SD Card program can read the hex or binary file of the new code, you have to fix a File Allocation Table (FAT32) stack in the bootloader program.

- The proper sequence
A bootloader rewrites different addresses in its internal memory with information bytes. This needs the right sequence of command execution for erasure and writing on internal storage. Make sure the address written is correct and the bootloader doesn't delete instead.

- Mapping to the correct address
Applications start from 0x00000000. A bootloader, however, is different and it depends on the allocation in the program space. Make a modification of the memory's file to ensure hex files of the two programs go to the right address.

- Testing
An SD bootloader simplifies the code, not to compound on errors. Test your bootloader rigorously to ensure everything runs as planned and to prevent the system from erratic behavior.

The Hellenic Heritage Foundation (HHF) is pleased to announce the launch of the podcast series: The Idea of Greece.
Produced by the HHF's award-winning History Committee, The Idea of Greece is a seven-part podcast exploring the Greek Revolution of 1821.
Each podcast will explore a part of the revolution and formation of the Greek state going beyond stereotypes and providing a clearer, more complex account of our heritage. The project is under the auspices of Greece 2021, the global project by the Greek State, marking the 200th Anniversary of the Greek Revolution.
The podcast is hosted by journalist Georgia Balogiannis and Prof. Sakis Gekas, the HHF Chair in Modern Greek History at York University. It is sponsored by Agape Greek Radio with original music by Toronto musician Demetri Petsalakis.
Episodes drop every two weeks and you can download them on Spotify, Stitcher and Apple Podcasts.
Most diaspora Greeks learned a very rudimentary version of the Greek Revolution in Greek School. It was a very black and white version of events from a dated curriculum steeped in nationalism. Drawing on the expertise of various academics and researchers, The Idea of Greece strives to present a more fulsome account of what life was like in the 1820s and what motivated people to join the Revolution.
The podcasts series will look at motivations, the battles and tactics used in warfare, the heroes and who they really were, the women who participated in the Revolution, how the international community got involved and how the modern Greek State evolved after the fighting ended.
"Even though I teach about the 1821 Revolution in a more thorough manner at the Modern Greek History program at York University," says Prof. Gekas, "this podcast series is an excellent opportunity to contribute to the public history of the Greek Revolution and engage as many people as possible."
In 2018, the HHF's History Committee launched the year-long commemoration of the 1918 Anti-Greek Riots in Toronto. That campaign won the Heritage Toronto 2019 Community Heritage Award.
Where: On Stitcher, Spotify and Apple Podcasts and HHF.ca
When: Monday, January 4th, 2021 and every other Monday
What: The Idea of Greece, a podcast about the 1821 Revolution by the award-winning Hellenic Heritage Foundation's history committee

An Approach to Determination of Curing Time in Stabilization of Swelling Soils with Lime Column
ABSTRACT:Swelling soils which are problematic in terms of geotechnics should be determined in preliminary works a n d appropriate cautions should be taken. The most frequently used method among the cautions to be taken is to stabilize soil with in-situ operations. One of the most widely used stabilization methods is lime column technique. Before stabilizing a swelling soil with lime column technique, it is investigated if the lime column works for the soil. This is done by creating a small-scale model of the land in the laboratory. The created models are left for a specific curing time to ensure the stabilization. Determination of the appropriate curing time is important for the performance of lime column. The aim of this study is to determine the curing time for the laboratory models, which are designed for investigating lime column performance, with an easy a n d economic method. The method is based on measuring the ion migration distance by using phenolphthalein which is an acid base indicator. In the scope of the study, a small scale laboratory model was designed for a Na-bentonite clay. The ion migration distance from the lime column in the model was measured by using phenolphthalein in various curing times a n d the measurements were stopped when the ion migration distance reached a constant value. The time in which the ion migration distance started not to change was taken as the cure time. The results obtained in this study showed that phenolphthalein can be a useful tool for determination of curing time in the laboratory applications of lime column.

When making caramel candy the recipe often calls for boiling a water/sugar/butter mix to one temperature, then adding cream and boiling to another temperature. Often the second temperature is higher than the first. I assume the second temperature is set to get the proper amount of water driven off and the proper caramelization of the sugar. What is the purpose of the first boiling? How would the result be different if we just mixed the water/sugar/butter/cream and boiled to the second temperature? If the first one is higher I can see we get more caramelized sugar that way, but if the second is higher I don't see the purpose.
When caramelizing sugar in a recipe that uses water your first job is to get the sugar to completely dissolve. That is the first temperature you are using. They are probably making you pause at this temperature long enough to make sure you do this tep correctly. If they didn't have the step most folks would blow past it, add more ingredients and run the risk of not dissolving the sugar correctly.
Make sure no sugar crystals remains at the first stage, even on the side of the pot. If any crystals remain or fall in later your recipe will fail because the sugar will recrystallize leaving a grainy taste.
Caramel and other candies like toffee start off with a small amount of water and are brought up to around the boiling point of water and held there briefly (typically a couple minutes) until the water is boiled off (which then allows the temperature to rise to the desired sugar stage). The reason for this is that when sugar is heated in the presence of water it undergoes a slow reaction called hydrolysis where the sucrose breaks down into fructose and glucose (this combination of fructose and glucose is referred to as invert sugar). Invert sugar impedes the crystallization of sucrose and helps produce the desired texture of the candy. Alternatively, invert sugar can be introduced to the recipe to reduce the time spent at the first boiling stage or skip it entirely. High fructose corn syrup is a common source of invert sugar used for this purpose in many commercial candy operations.

tested whether the magnitude of association between self-esteem and happiness would differ between local regions in the same country (i.e., Japan), varying in their relative degrees of relational mobility. Results showed that this association was stronger in areas where people more frequently changed their jobs than in those where job mobility was lower (Study 2). Study 3 experimentally manipulated participants' perceived relational mobility using a priming technique, and tested if this manipulation would affect the degree of association between self-esteem and happiness. Supporting the prediction, it was found that this association was stronger when participants were asked to recall the situations when they had talked with strangers than when they had talked with their family (Study 3). There are, however, some weaknesses inherent in these studies. First, both Studies 1 and 2 showed that, as predicted, relational mobility of local and regional ecology moderated the strength of association between self-esteem and happiness, but there are a number of other possible confounding factors between the countries and regions, including language, economy, climate, etc. Second, although Study 3 used a priming technique and successfully indicated the predicted causal relationship between relational mobility and the association between self-esteem and happiness, the manipulation changed perception of relational mobility, not the actual levels of relational mobility that existed in the environment. Therefore, we conducted a new study, which sought to control for confounding factors as far as possible, employing a quasi-experimental method, which examined two similar groups of people who were facing two similar circumstances that crucially differed in the associated levels of relational mobility.
In the present study, we aimed to test whether a change in the degree of relational mobility in the surrounding social context would affect the magnitude of association between individuals' self-esteem and happiness. More specifically, using a quasi-experimental method, we observed if the strength of this association among Japanese students who belong to the same university might change between the time when they have just entered college and there are abundant chances to meet and select new friends (high relational mobility), and when they have entered their second year and relationships tend to be more stable and exclusive (low relational mobility). Although research has shown Japan to be a typical low relational mobility society, when compared with the United States (e.g., Schug et al., 2009, 2010; Yuki et al., 2013), there are a varieties of circumstances and places when and where relational mobility is particularly higher than average (Yamagishi et al., 2012; Yuki et al., 2013). The college situation right after entrance (i.e., the few months after April for the first-year students) can be one such typical situation.
This study is intended to address the limitation of the previous studies by Yuki et al. (2013) as first, it could exclude the historical or cultural confounding factors of specific regions (e.g., the United States vs. Japan or urban vs. rural). Thus, an important strength of the current study is that we could adopt a "just minimal difference" paradigm (Uskul et al., 2008) that allows us to keep constant as many potentially confounding variables as possible in order to test the hypothesis. For our comparison groups, we used different academic years from a sample of students from the same university. These students share the same general nature of living (i.e., all students live in the same city and its suburb and about the half of them live quite near to the university), the same academic stage, and similar daily lives and backgrounds (i.e., family income). Thus, we could control not only personal but also many surrounding socio-ecological characteristics with the exception of relative levels of relational mobility. The second advantage of our present approach was that it allowed us to test the hypothesis without attempting to induce some change in cognition or perception of the social environment but rather relied on a "real" change of social contexts.
In the present study, we specifically predicted that: (1) relational mobility should be higher among the first-year university students than among the second-years and (2) the magnitude of association between self-esteem and happiness should be stronger among the first-year than the second-year students. To the best of our knowledge, the present study is the first study to investigate the moderation effect of relational mobility on the association between self-esteem and happiness by comparing cross-contextual differences in relational mobility using a quasi-experimental design.
Materials and Methods
Five hundred and thirty seven Japanese university students [344 first-years (251 male, 93 female), 193 second-years (110 male, 83 female)] participated in this study. The mean average age for the first-years was 18.47 (SDage = 0.70) and 19.50 for the second-years (SDage = 0.67).
Procedure and Materials
We conducted the survey at the end of April and the beginning of May, which is about a month after a school year starts in Japan. Given the generally low relationally mobile nature of interpersonal relationships among Japanese university students (e.g., Schug et al., 2010; Yuki et al., 2013), the first-year students at this time of the year are supposed to be experiencing one of the rarely relationally mobile contexts of their student lives.
Participants who volunteered to take the survey completed the questionnaire packet in a class setting. We administered two sets of questions in order to confirm our assumption that the first-year and second-year students resided in social environments that differed in their relative degrees of relational mobility. First, we asked participants about their perception of relational mobility in their immediate social environment using the relational mobility scale (Yuki et al., 2007). Sample items include: "They (i.e., people in my immediate society) have many chances to get to know other people" and "They can choose who they interact with." Second, we asked the participants to report the number of new friends and acquaintances that they had made in the past month in order to provide an indirect self report measure of personal rather than perceived societal relational mobility (Schug et al., 2010). Finally, we asked participants' about their happiness and self-esteem (in that order) employing the 5-item Satisfaction with Life Scale (Diener et al., 1985; Rosenberg's,1965) 10-item scale, respectively. We chose these particular scales as they are the most frequently used and well-validated scales available to assess happiness (e.g., Diener and Diener, 1995) and self-esteem (e.g., Schmitt and Allik, 2005). Sample items from the satisfaction with life scale are, "In most ways my life is close to my ideal" and "I am satisfied with my life" and for the Rosenberg self-esteem scale, examples are "I feel that I am a person of worth, at least on an equal plane with others" and "I feel that I have a number of good qualities." All measurements were made on 6-point scales ranging from 1 (strongly disagree) to 6 (strongly agree), with the exception of the question concerning the number of new acquaintances made.
Table 1 shows the scale means, standard deviations, and reliability coefficients for each scale. First, we calculated the reliability of items for each scale. All the scales were highly reliable: Rosenberg's self-esteem scale (α = 0.84), satisfaction with life scale (α = 0.78), and relational mobility scale (α = 0.81). Thus, we calculated the average of each scales to generate an overall scale score.
TABLE 1. Means and standard deviations of, and intercorrelations among, variables by first vs. second-year students.
Second, we checked if the first-year and second-year students were, as expected, facing situations varying in the degree of relational mobility. As predicted, perceived relational mobility was higher among the first-years (M = 4.03, SD = 0.58) than among the second-years (M = 3.88, SD = 0.56), t(535) = 2.86, p = 0.004, d = 0.26. Moreover, the first-years self reported that they had obtained a greater number of new friends and acquaintances in the past month (M = 40.03, SD = 29.57) than the second-years (M = 15.21, SD = 23.16), t(523) = 10.64, p < 0.0001, d = 0.91 (Table 1)1,2. These results confirmed our assumption that our first-year students were indeed in a social context higher in relational mobility than the second-year students.
Next, as the main analysis, we compared the strengths of correlations between self-esteem and happiness between firstand second-years. As can be seen in Table 2, the correlation was stronger for first-year students (β = 0.53, p < 0.001) than for second-year students (β = 0.38, p < 0.001). This observation was confirmed by a multiple regression analysis where self-esteem, school year (dummy coded as first-year student = 1, second-year student = 0), and a self-esteem × school year interaction effect were entered as the independent variables, with happiness as the dependent variable. The results showed, in addition to the main effect of self-esteem, there was also a significant interaction effect between self-esteem and school year (β = 0.11, p = 0.026), with the strength of association between self-esteem and happiness stronger for first-year students than second-year students (Figure 1), thus supporting our prediction (Table 2: Fisher's z regarding the difference in the strength of

Cholesky-factorized sparse Kernel in support vector machines
Document typeMaster thesis
Rights accessOpen Access
Support Vector Machine (SVM) is one of the most powerful machine learning algorithms due to its convex optimization formulation and handling non-linear classification. However, one of its main drawbacks is the long time it takes to train large data sets. This limitation is often aroused when applying non-linear kernels (e.g. RBF Kernel) which are usually required to obtain better separation for linearly inseparable data sets. In this thesis, we study an approach that aims to speed-up the training time by combining both the better performance of RBF kernels and fast training by a linear solver, LIBLINEAR. The approach uses an RBF kernel with a sparse matrix which is factorized using Cholesky decomposition. The method is tested on large artificial and real data sets and compared to the standard RBF and linear kernels where both the accuracy and training time are reported. For most data sets, the result shows a huge training time reduction, over 90\%, whilst maintaining the accuracy.

if they like school. The results were almost even: 64 kids said yes, and 62
We like school. One reason is that we can make new friends there.
We also think it's fun to do school projects and we like learning new
things. Competing in school sports can be fun, too.
We talked to kids who are not glad that their summer vacation will soon end.
Some said the reason they don't like school is because they don't like
Some said they don't like sitting through boring school lessons. And some
said the schoolwork is too difficult.
School can be a little challenging, but we don't think it's a waste of time.
If kids don't go to school, they probably will have a difficult time
getting a job when they grow up.

When I first read about the microSD card feature of the Gen6 board that comes with the Portabee 3d-printer I regarded it as totaly useless. But after a lot of mysterious connection problems between Pronterface and the Portabee during the print apparently triggered by other electrical appliances in the same room I started to investigate the issue.
Sometimes, when I switched on the lights of the room or my soldering iron the Portabee stopped. Pronterface showed an error message which said something about a connection problem. Pronterface was not able to connect to the printer again and I needed to restart both! the printer and the PC. This problem was caused by electromagnetic interferences to the Gen6 board. USB is quite prone to EMI effects via the power line. Large motors, a fan for example, starting and stopping on the same ring main can cause power spikes and knock out the USB connection. I searched the Internet and found a lot of suggestions like buying an uninterruptable power supply or making a shielded case for the board and connect it to ground or buying a higher quality usb cable or just shorten the usb cable. But a different solution seems much easier: Print from an microSD card.
How it works
Format the microSD card to the FAT32 format. Copy the GCode files to the microSD card. For the GCode files use file names in the 8.3 format. That means the file name must have at most eight characters, optionally followed by a period . and a filename extension of at most three characters. Example: FOO.G. Check the microSD card for hidden files and folders and remove them. My Linux distribution automatically created a .Trash folder which caused a lot of problems. Insert the microSD card in the board. If you are using Pronterface select SD and SD Print. Pronterface will show a list where you can select the GCode file and start the print. Pronterface will then show the progress and the temparatures during the print and allow to stop the print process. But be aware to never disconnect the USB cable from the PC during the print because the Portabee 3d-printer will stop.

Correct. Common strategy is to either persist a setting into application settings or to save a value to a file at the very end of the process.
The logic becomes:
1. Is my special value there?
2. Yes - great, database is populated, business as usual
3. Nope - OK, load up the database
4. Last step after loading up the databes, set my special value
In the emulator if you rebuild or close and open then yes, you'll end up in steps 3 - 4.

Liquid phase crystallized silicon on glass: Technology, material quality and back contacted heterojunction solar cells
Liquid phase crystallization has emerged as a novel approach to grow large grained polycrystalline silicon films on glass with high electronic quality. In recent years a lot of effort was conducted by different groups to determine and optimize suitable interlayer materials, enhance the crystallographic quality or to improve post crystallization treatments. In this paper, we give an overview on liquid phase crystallization and describe the necessary process steps and discuss their influence on the absorber properties. Available line sources are compared and different interlayer configurations are presented. Furthermore, we present one-dimensional numerical simulations of a rear junction device, considering silicon absorber thicknesses between 1 and 500 mu m. We vary the front surface recombination velocity as well as doping density and minority carrier lifetime in the absorber. The simulations suggest that a higher absorber doping density is beneficial for layer thicknesses below 20 mu m or when the minority carrier lifetime is short. Finally, we discuss possible routes for device optimization and propose a hybride cell structure to circumvent current limitations in device design. (C) 2016 The Japan Society of Applied Physics

NEW YORK (AP) — Scientists say they've found evidence that stone tips for spears were made much earlier than thought, maybe even created by an earlier ancestor than has been believed.
Both Neanderthals and members of our own species, Homo sapiens, used stone tips, which made more lethal hunting weapons. The new findings suggest that maybe they didn't invent that technology, but inherited it from their last shared ancestor. That would be Homo heidelbergensis (hy-dil-ber-GEN-sis).
The study concluded that a collection of stone tips from South Africa was half-a-million years old. That's 200,000 years older than stone tips found elsewhere.
The work was published Thursday by the journal Science.

We have examined the effects of excitatory amino acids on tetanus-induced long-term potentiation (LTP) in the CA1 region of rat hippocampal slices. Agonists acting at N-methyl-d-aspartate (NMDA) receptors, including NMDA, aspartate and glutamate, completely block the development of LTP when administered for 5 min prior to tetanic stimulation. Additionally, and unlike the NMDA receptor antagonist 2-amino-5-phosphonovalerate (APV), NMDA blocks LTP when administered for 5 min immediately following the electrical tetanus. The effective concentrations of NMDA are subthreshold for depolarizing CA1 neurons. These results indicate that under certain conditions NMDA receptor activation prevents CA1 LTP.

History of APBY
The history of Asia Pacific Baptist Youth dates back to 1953 when the Baptist Youth around the world met for the 4th Baptist World Youth Conference in Rio de Janeiro, Brazil.
One of the first initiation for the formation of ABYF came from Akiko Endo (Later Mrs. Matsumura) whose vision led to an October 10 meeting in 1954 in Sri Lanka. Joel Sorenson, who was the Youth Secretary of the Baptist World Youth, was invited by Willie Wikramasinghe followed by visits to India, Hong Kong, Japan, Taiwan, Philippines, Thailand and Myanmar.
Following the visit of Joel Sorenson, and correspondence amongst the leaders in Asia resulted in the first meeting of Asia Baptist Youth Fellowship on August 20, 1956. Hong Kong, Japan, India, Sri Lanka, Korea, Macau, Malaysia, Indonesia, Philippines, Myanmar, Taiwan and Thailand answered the roll call parade of nations at the 1st Asian Baptist Youth Conference held in Hong Kong.
In 2006, at the 7th Congress of the Asian Baptist Federation in Chiang Mai, Thailand, the nomenclature of Asian Baptist Youth Fellowship was changed to Asia Pacific Baptist Youth.
Asia Pacific Baptist Youth continues to serve and represent Baptists around the Asia Pacific region as regional body to the Baptist World Alliance Youth Department.
The Asia Pacific Baptist Youth (APBY) is an organization of Baptist Youth in various churches and Baptist groups under the Asia Pacific Baptist Federation. APBY seeks to build a network among Baptists, regionally, with the aim to promote fellowship, provide training and be challenged to respond to various needs of young people in our region. Once every five years, the APBY comes together for a gathering called the APBY Conference to celebrate God's work among the Baptists in Asia-Pacific continent.
APBY seeks to engage, build a comprehensive network among the APBY member bodies, to help, support and train young people to become future leaders in a yearly basis.
APBY will work to update information, news, on different ministry opportunities among member bodies to achieve effectiveness in their ministry responsibilities. APBY will plan a yearly program for leadership development by holding leadership conference within the Asia-Pacific continent.

Experimental Measurement of Multiphase Flow and CFD Erosion Modeling in Electrical Submersible Pumps
MetadataShow full item record
Electrical Submersible Pumps (ESPs) are widely being used in upstream oil production. To better understand the ESP pump?s behavior, two different ESPs, MVP-G470 and ESP-WJE1000, manufactured by Baker Hughes company have been studied experimentally and numerically to determine the pump and flow behavior in different operating conditions and for different working fluids. The MVP-G470 is a multi-vane electrical submersible pump which has been designed to increase the gas handling capacity of typical multiphase ESPs up to 70% gas volume fraction. Homogenized flow and finer bubbles produced by MVP pumps help the ESPs to delay the surging and gas lock condition to higher gas volume fractions and operate effectively. In this work, an experimental study on the performance of a 3-stage MVP along with detail study on the performance of two stages of the pump are performed. Overall pump performance for different operating conditions such as different inlet pressure, inlet gas volume fraction, water flow rate and speeds are performed for a mixture of water and air. Detail study of a stage performance is done on the first and second stage of the pump using conductivity and pressure measurements accompanied by high speed visualization. The data obtained from these measurements is employed to relate stage head degradation to effective parameters on the pump performance. The ESP-WJE1000 is a typical mixed flow ESP pump with a single vane rather than split-vane design used in MVPs. Numerical study on the erosion phenomena in this pump has been performed. The influence of key parameters on erosion in ESPs has been identified and a new model to predict the erosion rate at different pump locations has been introduced.

Four Parts:Making the WashFermentationDistillationFinishing off the Rum
Yield: Approximately 2-3 L (0.5 - 0.8 gallons) rum
 - 2.5 kg (5.5 lbs) molasses
 - 2.5 kg (5.5 lbs) processed sugar
 - 20 L (5.2 gal) distilled water
 - 42.5g (1.5 ounces )hydrated yeast
 - Additional distilled water to dilute the final solution
Part 1 of 4: Making the Wash
 1. Make Rum Step 1.jpg
 Begin by placing 20 L of water in a clean boiler. The operative word is clean. The slightest bit of contamination can spoil the rum. Before you start, make sure you're dealing with the cleanest ingredients and a sanitary area.
 - Clean and then submerge any utensils you will be using in boiling water. Turn the heat off the boiling water and soak your pot or barrel in the near-boiling water. Then dump the water. This will help kill off any potentially harmful germs.
 2. Make Rum Step 2.jpg
 Dissolve both the sugar and molasses in 20 liters of water over medium heat. The sugar will dissolve easily, but the molasses will be tougher dissolve, as it is very sticky. Try not to boil the water. Continue to let it heat up until bubbles just start to form, and then turn the burner off.
 3. Make Rum Step 3.jpg
 Cool the solution to 28 °C (82 °F) and add the hydrated yeast. You may find it helpful to take out about 1 liter of the mash in a jug first; try dissolving the yeast in the smaller jug. Then, when the mixture begins to foam up, incorporate with the rest of the wort.
Part 2 of 4: Fermentation
 1. Make Rum Step 4.jpg
 Allow solution to ferment at 25° C (77° F) until the airlock on your pot stops bubbling. The yeast needs heat to keep converting sugar to alcohol. So be sure to store the wash in a warm place or keep the room artificially heated. The airlock on the pot will let the carbon dioxide out without letting oxygen in.[1] It should take about 24 - 48 hours for the airlock to stop bubbling.
 - The airlock is a really important piece of the fermentation process. You can make an airlock yourself pretty easily, or you can buy one inexpensively.
 - Either way, be sure the airlock fits well and doesn't let additional air into the container. Why is it important that no air gets into the wash? The yeast feeds on oxygen from the sugar molecules, leaving ethyl alcohol behind (and spitting out carbon dioxide). If the yeast has a continuous supply of oxygen to eat, it won't be effective scavenging the oxygen from the sugar molecules.[2]
 2. Make Rum Step 5.jpg
 Once airlock has finished bubbling, allow the wash to sit for 3-7 days. You can use a hydrometer to test when the wash is ready. Hydrometers measure the ratio of a density of a liquid to the density of water. Measure once a day starting on the day when your wash should be finished. Take a bit of wash out of the container and put it into a graduated cylinder. Float the hydrometer into the cylinder, gently swirling the cylinder to release any bubbles. When you get the same reading on the hydrometer for three days straight, your wash is ready to distill.
 3. 3
 Knock your yeast down by lowering the temperature. At this point, your yeast may still be on the surface of your wash. Allowing the yeast to enter the still during distillation will cause bad smells and flavors.[3] To knock the yeast down to the bottom of the wash, you should move your wash to a cool place — ideally, 10° - 14° C (50° - 57° F) — and wait up to two days. At this point, you can siphon your wash directly into the still or rack it and save a part of the yeast for another batch in the refrigerator.
Part 3 of 4: Distillation
 1. Make Rum Step 6.jpg
 Place a collection vessel under the distillate valve to catch your alcohol solution. It's very important that all connections are tightly sealed and fit well.
 2. Make Rum Step 7.jpg
 Connect a water source to coolant input. You want a water source to cool the alcohol vapor. As the alcohol vapor cools, it condenses into liquid ethanol. This will then drip from the condenser into a collection vessel.
 3. Make Rum Step 8.jpg
 Now siphon the solution into the still. Be sure to siphon the wash carefully, avoiding the bottom, where the yeast collected.
 - A siphon is a tube or conduit bent into legs of unequal length, for use in drawing a liquid from one container into another on a lower level. Siphoning works by placing the shorter leg into the container above and the longer leg into the one below. The liquid is forced up the shorter leg and into the longer leg by the pressure of the atmosphere.
 4. Make Rum Step 9.jpg
 Begin slowly bringing the solution to a boil. For rum, a slow boil is best; no need to crank it up. Begin running cold water once the solution reaches between 50-60°C (122-140 °F). The solution will start distilling when clear drops of liquid start to exit the spout into the collection vessel.
 5. 5
 Discard the first 100mL (3.38 fl. ounces) of clear liquid. This is called the "heads," and is routinely discarded for safety precautions. The heads contains volatile methanol, which can lethal if ingested. Better to be safe than sorry, especially when you're distilling three liters of spirit.
 6. Make Rum Step 10.jpg
 Collect the next 2-3 L of distillate exiting the spout. Stop collecting once temperature reached 96 °C (204.8 °F).
 7. Make Rum Step 11.jpg
 Turn off the heat source, then turn off the cold water.
 8. Make Rum Step 13.jpg
 Open the lid to still so as to avoid creating a vacuum inside your still.
Part 4 of 4: Finishing off the Rum
 1. 1
 Age your rum in oak barrels or toasted oak (optional). Often, rum is aged in toasted oak barrels for 10 years or longer to add depth of flavor and color. If you don't have the luxury of a toasted oak barrel, or 10 years' time, you can safely soak your rum in toasted oak chips for three weeks to impart a signature taste. Filter your rum through a cheesecloth or clean cotton shirt to catch any of the wood particles.
 2. Make Rum Step 14.jpg
 Use water to dilute alcohol to expected proof. Depending on the reflux still, your undiluted rum can be up to 95% alcohol, which is dangerously strong for consumption. Use a dilution calculator to bring your rum down to around 45% for the best taste experience.
 3. Make Rum Step 15.jpg
 Add flavors of other additives to improve the taste. Make spiced rum by adding cinnamon, ginger, and cloves to the final rum mixture, soaking for 1 - 2 weeks. Some choose to add a small amount of caramelized sugar to the rum.

 - Fractional distillation (the type of still here, a reflux still, is a form of fractional distillation) is normally required to achieve percentages as high as 95%, and is more common to rum specifically. Pot still distillation (as used for whiskey, many other alcohols, and some so-called "full-flavored" rums) is nearer to 70% (in double-distiller process) or 80-88% (in a triple distillation).
 - Common flavorings used in rums are: coconut extract (clear), sugar cane juice. One common (and perhaps overall the most common) to all but white flavored rums is molasses. A flavoring in gold and spiced rum is often caramel. Spiced rum may have cinnamon extract (certainly tiny amounts), or honey. Another possibility for Haitian-inspired rums might also include tiny amounts of mace extract and/or the flowers of basil.
 - Try using a larger pot next time. Other wise you will have one gooey mess. Also a funnel would help when pouring into containers.

Leveraging Learning Styles to Improve Student Learning: The Interactive Learning Model and Learning Combination Inventory
This paper describes the Interactive Learning Model, and a related instrument called the Learning Combination Inventory, which identifies those patterns of processing that learners rely upon as well as those patterns that learners avoid. It further reports the results of an exploratory study using MIS students, the purpose of which was to see if a correlation exists between those learning patterns that a student relies upon and their success in two different types of learning activities. The results suggest that if students understood their own learning patterns they could develop specific strategies to become efficient and effective life-long learners.

Why are there so few hurricanes every year?
We are about five weeks away from the climatological peak of the hurricane season, which stretches from early June to November.
During that period, even in a particularly active year, not many hurricanes actually develop. Forming over tropical oceans ensures that warm sea-surface temperature (SST) provides a mature hurricane with a means to warm and moisten the air that flows toward the important eye-wall convection. Thus, it is not surprising that hurricanes struggle to develop if the SST is not 79.7 degrees or warmer. Continue reading

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

Children can respond to disasters such as bushfires and floods in a number of ways, our son has recently started inserting fires into his creative play, smashing down lego creations as "fires" come to destroy everything.
It may be comforting to know that this is entirely normal behaviour, kids often process big emotions and issues through play. Perhaps you've noticed your children processing their feelings, how are your children/grandchildren processing the bush fires we've been experiencing for several months?
The disaster is hard to avoid, and you can't ignore them, if you've experienced an evacuation, had your home or community destroyed or, if you've been breathing in the smoke for several weeks your children/grandchildren would have experienced it too.
It may be the case that you're struggling to find ways to support your children or grandchildren at this time, being there is of utmost importance, showing them you're with them is of utmost importance, everything else flows from being present.
What follows are some articles and resources which I hope can help you think through how you work through these big feelings and issues together.
If you find any of these helpful, or if you've used other resources please let us know.
Kinderling – Helping Kids Cope With Bushfire Stress
I'll start with resources from Kinderling, (via Babyology) Initially they link to an episode of the Feed Pray Love podcast focussing on "helping children cope with fires" in which Margaret Nixon, the workforce officer for the National Workforce Centre for Child Mental Health discusses how parents (and grandparents) can help children during this emergency.
They then list a number of ways to support children through the stress brought out by the current bushfires:
- Being there matters most
- Children need reassurance and information
- Creating new routines
- Watch out for stress signals (in which they list a number of trauma responses)
- Look out for silver linings together
- Keeping kids safe from media coverage
Unicef – How to Talk to Your Children About Australia's Bushfire Emergency
UNICEF have a great article exploring how to talk with children overwhelmed by Australia's bushfire emergency.
"UNICEF's years of experience in providing counselling and emotional support to children impacted by disaster tells us that children and young people respond differently to disaster than adults."
Their list gives a number of tips for discussing the bushfires with your children, grandchildren, nieces and/or nephews:
- Focus on the child, not the distress
- Be honest, explain the truth
- Offer reassurance
- Help children get back to their normal routine
- Show them all the good people trying to help
- Show them they can help
- Take care of yourself
The Conversation – Bushfires Can Make Kids Scared & Anxious: Here Are 5 Steps To Help Them Cope
The Conversation has a great article by the people behind the Bounce Back program ( _URL_ ) on building resilience and lessons learned from working with students after the 2009 bushfires in Victoria.
Resilience is the capacity to bounce back after hardship. To help your child bounce back, you can communicate that:
- Life is mainly good but now and then everyone has a difficult or unhappy time
- Although things aren't good now and it might take a while to improve, it's important to stay hopeful and expect things to get better
- You will feel better and have more ideas about what to do if you talk to someone you trust about what's worrying or upsetting you
- Unhelpful thinking ("our family will never get a nice home again") isn't necessarily true and makes you feel worse
- Helpful thinking ("it might take a while to get our home back again but it will happen") makes you feel better because it is more accurate and helps you work out what to do.
Birdie's Tree – Growing Together Through Natural Disasters
Birdie's Tree is the work of the Queensland Centre for Perinatal and Infant Mental Health. The website includes:
- Therapeutic online games for children to play online (building a face, colouring in, singing songs…)
- Story flipbooks of Birdie and her friends experiencing natural disasters (fire, cyclone, floods, drought, sickness…). These stories can be read as families or in the classroom.
- Information and resources from the Child and Youth Mental Health team from the Queensland Hospital on recovering together through different natural disasters.
- A Curriculum for teachers and carers to help infants, young children and families recover emotionally from the 'big feelings' a natural disaster can cause.
Emerging Minds – Community Trauma Toolkit
Finally I've recently been introduced to the Community Trauma Toolkit from Emerging Minds, I've not had any time to really check it out, but it's come from a reliable source.
"This toolkit contains resources to help and support adults and children before, during, and after a disaster or traumatic event. It will help you understand some of the impacts of disaster and how you can help lessen these impacts.
Emergencies and disasters are extremely stressful and it is normal to feel overwhelmed. Children, even infants, can also be affected. They depend on the adults around them for safety and security, and will need reassurance, care, and opportunities to share their feelings. These resources provide a starting point for you to help children navigate the different stages of a disaster."

Equation: Quantifying Light = Great 3-D Animation
Light is one of the most challenging aspects of computer-generated imagery. It bounces around, reflects off surfaces, and changes color; if you don't get all those elements right, your animation will look no more real than Bugs Bunny—not necessarily bad, but not what the folks at places like Pixar are going for. In the mid-'80s, mathematicians quantified this process: If you know the intensity and color of the light arriving at a particular spot, you can figure out the same information for the light that bounces off. Here's the equation at the heart of every 3-D rendering package.
The intensity in watts of a particular color (wavelength λ) of light from spot x to the viewer's eyeball.
Light emitted from x. Unless some object—a lamp, the sun, a firefly, phosphorescent algae—is emitting a glow at x, this will be zero.
A hemisphere around x. Each point on Ω represents one of the possible directions from which light could hit x.
Strain your brain back to calculus and you may remember that this is a fancy summation—adding up infinitely many infinitely tiny things. Here, you take Ω—every possible angle light may travel to x—compute how much each unit of that light bounces toward your eye, and then add 'em all up.
This describes how much of the light that hits a material will reflect in a specific direction. A red surface, for example, will absorb every other color of light but red. A matte surface will spread light in all directions, reflecting only a bit toward your eye, while a mirrored surface will bounce all of the light in a single direction.
The amount of incoming light of wavelength λ that strikes x from a particular direction.
An adjustment for the angle of the light. Just as the low winter sun offers less heat than the high summer sun, less of the light coming from a low angle will bounce off x toward the eye than that arriving from a high angle.
An infinitely small section of the hemisphere Ω around x—in other words, just one of the directions from which light could strike spot x.
Software for making animated films like Despicable Me relies on the equation above to model how light interacts with objects.

Iu Mien is Hmong-Mien language spoken by about 840,000 people mainly in China, Laos, Vietnam, Thailand, and also in the USA. Iu Mien speakers are known as Yao - 瑶族 in Chinese, and người Dao in Vietnamese. They are one of the officially recognized ethnic minorities in China, and are also officially recognised as an ethnic group in Vietnam. Iu Mien is closely related to Kim Mun (Lanten), Biao-Jiao Mien, and Dzao Min.
In China the dialect spoken in Changdong in Jinxiu Yao Autonomous County in Guangxi is consider to be the standard. Iu Mien is also spoken in in Guangdong, Yunnan, Hunan and Guizhou provinces.
Iu Mien was written with Chinese characters in China for several centuries, then a Romanized script was devised for the language by Western linguists in the 1930s. The Iu Mien Unified Script, based on the Romanized script used in China, was created at a literacy conference in Guangdong province in 1984 by delegates from the USA, China, and Thailand.
The tone letters appear at the ends of words and are used to indicate the different tones of Iu Mien.

Pratt vs Howe Truss
 Hi, I have to build a Popsicle Stick bridge for Physics class. I really don't have much knowledge on bridges as most of this was to be researched. I did a lot of research but I'm having trouble deciding between these two trusses.
 Length: 55 cm
 Height: 4 cm
 Width: 8 cm
 So my main problem is the type of truss to use, Howe or Pratt. The load will be focused in the center.

 I used a Bridge Designer program to determine the force/weight distribution for each truss. Pratt is on the top, Howe is on the bottom:
 The main differences are that the Pratt truss has no force on the ends and the compression members are vertical. The Howe truss has no force on the center and the tension members are vertical instead.
 Here's why I can't decide between the two:
 - The Pratt truss uses vertical compression members. Since the height restriction is 4cm, wouldn't this allow the bridge using a Pratt truss to be stronger against compression? (Compression is inversely proportional to length, according to the research I've done)
 - The Howe truss has no net force in the center, where the load will be placed. Does this automatically make it better than the Pratt?

 It appears that you have inadvertently applied your load at the top of the truss instead of at the bottom, because that's the only way you're going to get a zero force in the center vertical chord for the Howe, and as compressive force of 150 for the Pratt (the way you have shown the load, those chord forces would be reversed). Beyond that, if your numbers are correct, I'm not sure which is better, it depends a lot on your l/r ratios for the compressive members. Off hand, you've got to weigh the 300 max tensile,225 max horiz chord compression, and 106 max compression of the diagonals, of the Howe, with the 187 max tensile and 250 max compression of the horiz chords, of the Pratt. And even for the zero force members, you're still going to use the same size popsicle stick in those members, so the zero's don't gain you anything. I'd vote for the Pratt, but it could be a wash either way. Just a thought, so don't take it for gospel. I'll let you be the engineer.
 4. Thanks for your help.
 The weight is going to be loaded on the top of the bridge in the center. Does that change anything?

 If the loading is as the top, your internal force diagrams as shown are correct.
 6. How about the deflection (vertical movement) at mid span. Does one indicate less deflection than the other? Also noticed that the maximum forces in Howe truss are less than the maximum in the Pratt. On a much larger scale, would the truss with the lower maximum forces result in in a lighter truss members, thereby reducing fabrication and erection costs?...
Have something to add?

Hazardous weather can occur at any time of the year. During the winter, the potential for icing, heavy snowfall, and power outages exist even in Las Cruces, New Mexico. During the spring, high winds are common. In the summer, extreme heat, thunderstorms, flashfloods, and tornados are all possible. In the fall, the potential for thunderstorms and hail are still high.
To help the campus community prepare for hazardous weather, NMSU has taken a number of steps. The first measure is to become a Storm Ready university, one of less than 50 in the nation. This shows the dedication of the university in helping the community be aware of, and prepared for, hazardous weather.
The NMSU Emergency Dispatch Center monitors weather information from the National Weather Service and other sources continually. If hazardous weather warnings and watches are issued, the dispatchers help determine the potential impact to NMSU and put out warnings as appropriate.
In most cases, seasonal warning information is distributed by NMSU Police once or twice in order to help people prepare for the upcoming season. Then, as severe warnings and watches are issued, additional notices are distributed as appropriate to the campus community. In the event of immediately life-threatening warnings (such as a tornado), NMSU may also activate the Emergency Notification System and the outdoor sirens.


The Dangerous Instagram Trend That's Harming Your Pets
In a worrying trend across social media, pet owners everywhere are dressing up their animals in anti-COVID face masks, a seemingly cute and innocent photo opportunity that could have potentially fatal consequences.
can my dog wear a mask?
Reasons for taking snaps of masked moggies or pooches vary in intention, with some influencers aiming to send out an adorable but persuasive post aimed at anti-maskers, while others are merely on a quest for likes or genuinely fearful their pet might contract the virus.
But whatever people's reasoning, the reaction from veterinarians and animal experts have all been the same and many are now warning pet owners of the severe stress and anxiety face coverings can cause pets.
Why Putting Masks On Pets Is Dangerous
Despite there being rare and isolated cases of dogs and cats contracting coronavirus, there is currently almost no evidence suggesting they can pass the disease on to humans and so masking up a pup is still certainly not a necessary action.
However, in this age of mistrust, many pet owners are ignoring the lack of evidence and still covering up their pets to be on the safe side.
The vast majority though are merely donning their dalmatians in masks for likes and attention on their social media accounts, with many even using it as a photo opportunity to appeal to face covering and COVID sceptics.
poodles in face masks for pandemic
But even if it looks really cute, it certainly isn't clever and according to Melbourne Veterinarian Dr Melissa Meehan, forcing a dog in particular to wear a face mask could kill them in a worst-case scenario.
Speaking to Yahoo News, Dr Meehan said: "As a vet, I am constantly treating dogs and cats that suffer from stress and anxiety, which impacts on their health and mental wellbeing and also causes behavioural issues,
"Putting a mask on a dog or cat can absolutely cause distress."
Forcing an animal to wear such a covering over their face is, therefore, going to be very agitating for them and could cause them health issues if worn for long periods of time.
She also made it clear that masks can impair an animal's breathing, "which can increase their stress levels and could even be fatal."
shihtzu in mask
This is especially true of certain breeds of dogs such as brachycephalic types who already typically suffer from breathing difficulties.
Adding a mask into the equation is only going to make the basic requirement to breathe even more of a struggle, putting their life at risk.
Unfortunately, this is not exactly a new trend either.
In the early days of the COVID-19 outbreak in Wuhan and various areas of China, plenty of people were photographed or filmed placing face masks on their beloved pets.
In their defence, the virus was still a very unknown quantity then and they were probably rightfully worried about the safety of their animals.
do pets need a mask for covid
However, even though there is still much to be discovered, evidence that animals can spread the disease remains non-existent.
This means the current bombarding of mammals in masks on Instagram is cruel and harmful to pets and doesn't actually do them or you any good.
So while we humans definitely should be campaigning to each other to all wear masks, are moggies and pooches shouldn't have any part in the advertising.
We'd much rather see you in a mask than Rover!
Why Pets Don't Need To Wear Face Masks
All over the globe, guidelines from various governments and scientists have promoted the wearing of masks to help prevent the spread of coronavirus, with some declaring it mandatory in closed public spaces.
For example, in the UK this week, face coverings were made compulsory in shops, supermarkets and on public transport, a rule many people have instantly adhered to.
why pets dont need masks for coronavirus
In a woeful case of timing though, a pet cat also became the first case of its kind to test positive for coronavirus in the UK, sending many people into panic mode.
So even if people are merely uploading masked photos of pets for fun or because it's 'cute', you may well be convincing other nervous and worried pet owners that popping a face covering on your pet is the done thing!
why cats shouldnt wear masks covid
But although several cats and dogs have now tested positive for coronavirus around the world, it remains a rare occurrence.
It's also important to note that each animal to contract the virus so far has displayed very low traces of it in their system and have also been unable to spread it to another human.
The World Organisation for Animal Health has stated that currently, there is no evidence to suggest that animals infected by humans are playing a role in the spread of COVID-19,
Human outbreaks are driven by person-to-person contact and to date, there is no evidence that companion animals have spread the disease.
This means that the handful of pets who have been unlucky enough to catch the disease have done so from their owners, and not the other way round!
So if you're truly worried about your pet catching coronavirus, it's YOU who needs to wear a mask rather than them, as well as limit contact with them if you suspect you have symptoms.
Why would you ever want to hide away that adorable face anyway!?


single-corner-frequency spectrum, or as \(T=1/(\pi {f}_{{c}_{1}})\) for the double-corner-frequency spectrum. Assuming that the acceleration and velocity time series are non-stationary with uncorrelated peaks, the peak values (PGA and PGV) can be related to the rms values using random vibration theory (Cartwright and Longuet-Higgins 1956) via the relations
$$\frac{\mathrm{PGA}}{{a}_{\mathrm{rms}}}\approx {\left[2\mathrm{ln}\left({N}_{\mathrm{a}}\right)\right]}^\frac{1}{2}+\gamma {\left[2\mathrm{ln}\left({N}_{\mathrm{a}}\right)\right]}^{-\frac{1}{2}},$$

where Na and Nv are the number of zero crossings in the corresponding time series over duration T and \(\gamma\) is Euler's constant. The approximations in equations (B2a) and (B2b) are valid for \({N}_{\mathrm{a}}, {N}_{\mathrm{v}}\ge 2\). Finally, expressions for Na and Nv are given by
$${N}_{\mathrm{a}}=\frac{T}{\pi }{\left\{{\int }_{0}^{\infty }{\left[\widetilde{a}(f)2\pi f\right]}^{2}\mathrm{d}f/{\int }_{0}^{\infty }{\left[\widetilde{a}(f)\right]}^{2}\mathrm{d}f\right\}}^\frac{1}{2},$$

Invertible knot
From Wikipedia, the free encyclopedia
In mathematics, especially in the area of topology known as knot theory, an invertible knot is a knot that can be continuously deformed to itself, but with its orientation reversed. A non-invertible knot is any knot which does not have this property. The invertibility of a knot is a knot invariant. An invertible link is the link equivalent of an invertible knot.
There are only five knot symmetry types, indicated by chirality and invertibility: fully chiral, reversible, positively amphichiral noninvertible, negatively amphichiral noninvertible, and fully amphichiral invertible.[1]

It has long been known that most of the simple knots, such as the trefoil knot and the figure-eight knot are invertible. In 1962 Ralph Fox conjectured that some knots were non-invertible, but it was not proved that non-invertible knots exist until H. F. Trotter discovered an infinite family of pretzel knots that were non-invertible in 1963.[2] It is now known almost all knots are non-invertible.[3]
Invertible knots
 The simplest non-trivial invertible knot, the trefoil knot. Rotating the knot 180 degrees in 3-space about an axis in the plane of the diagram produces the same knot diagram, but with the arrow's direction reversed.

All knots with crossing number of 7 or less are known to be invertible. No general method is known that can distinguish if a given knot is invertible.[4] The problem can be translated into algebraic terms,[5] but unfortunately there is no known algorithm to solve this algebraic problem.
If a knot is invertible and amphichiral, it is fully amphichiral. The simplest knot with this property is the figure eight knot. A chiral knot that is invertible is classified as a reversible knot.[6]
Strongly invertible knots
A more abstract way to define an invertible knot is to say there is an orientation-preserving homeomorphism of the 3-sphere which takes the knot to itself but reverses the orientation along the knot. By imposing the stronger condition that the homeomorphism also be an involution, i.e. have period 2 in the homeomorphism group of the 3-sphere, we arrive at the definition of a strongly invertible knot. All knots with tunnel number one, such as the trefoil knot and figure-eight knot, are strongly invertible.[7]
Non-invertible knots
 The non-invertible knot 817, the simplest of the non-invertible knots.
The non-invertible knot 817, the simplest of the non-invertible knots.
The simplest example of a non-invertible knot is the knot 817 (Alexander-Briggs notation) or .2.2 (Conway notation). The pretzel knot 7, 5, 3 is non-invertible, as are all pretzel knots of the form (2p + 1), (2q + 1), (2r + 1), where p, q, and r are distinct integers, which is the infinite family proven to be non-invertible by Trotter.[2]

Abstract
The computing continuum model is a widely ac-cepted and used approach that make possible the existence of applications that are very demanding in terms of low latency and high computing power. In this three-layered model, the Fog or Edge layer can be considered as the weak link in the chain, indeed the computing nodes whose compose it are generally heterogeneous and their uptime cannot be compared with the one offered by the Cloud. Taking into account these inexorable characteristics of the continuum, in this paper, we propose a Reinforcement Learning based scheduling algorithm that makes per-job request decisions (online scheduling) and that is able to maintain an acceptable performance specifically targeting real-time applications. Through a series of simulations and comparisons with other fixed scheduling strategies, we demonstrate how the algorithm is capable of deriving the best possible scheduling policy when Fog or Edge nodes have different speeds and can unpredictably fail.

Nonisotopic detection of Loma salmonae (microspora) ...
|Title||Nonisotopic detection of Loma salmonae (microspora) in rainbow trout (Oncorhynchus mykiss) gills by in situ hybridization|
|Author(s)||J. G. Sanchez, David J. Speare, R. J. Frederick Markham|
|Abstract||Loma salmonae, a microsporidian parasite of salmonids of the genus Oncorhynchus, is a significant cause of economic loss in pen-reared chinook salmon (O. tschawytscha). Final stages of L. salmonae infections are easily recognized by the xenomas that form in the gills during sporogony. However, early prexenoma stages of infection (3 weeks or less after infection) are difficult to detect on histologic slides. An L. salmonae-specific single-stranded DNA probe labeled with digoxigenin was used to detect these prexenoma stages of L salmonae by in situ hybridization in experimentally infected rainbow trout. This method allows detection of the parasite in the gills only 2 weeks after infection, providing a sensitive and specific way of detecting L. salmonae during the early stages of infection.|

Agricultural drainage or land drainage is essential in ensuring that the soil is not saturated which is why it's so vital for agriculture. Keeping land well drained no only allows crops to flourish but it also means that the land is accessible to machinery at all times, making sure that you can continue on with the work that you need to do. This is the most effective and economical way of substantially improving crop yields so that you get the very best out of your land.
This practice has been used for many years and involves the collection, transportation and disposal of water away from crops, alleviating the problem of water logging. Our Trenching machines offer a good solution in ensuring your land stays well drained.
AFT100 Agricultural Drainage Trenching Machine
Our AFT100 trencher is ideal for installing agricultural drainage systems; it really is a great investment as it allows you to undertake this work at a fraction of what it would cost if you were to use backhoes, excavators or contractors with large self-propelled trenchers. You also have the option of contracting the trencher out to fellow farmers who may have the same concerns about water logging.
With an AFT100 trencher you have the possibility of laying pipe and gravel at the same time, using our hydraulic ripe reel carrier in conjunction with our combined pipe chute and gravel hopper. You can also perfectly set the slope of the trench using a semi or completely automated laser system.
These trenches are perfect for ensuring land doesn't get water logged and saturated which can have a negative impact on crops and can also cause accessibility issues.
