Turbo Equalizer Block Diagram
Short Description
Turbo equalization is a well-known approach to improve the overall performance of a wireless communication system. The underlying principle is to feed back soft information from the channel decoder to the channel equalizer and channel estimator in an iterative manner. However, due to the iterative nature of Turbo equalization there are severe challenges to meet latency requirements in almost all communication standards which is one of the reasons why Turbo equalization is found only seldom in practical receiver implementations today.
With the focus of communication systems being partly shifted from ever increasing throughput requirements to low-throughput, long-range communication systems in order to enable cellular IoT (Internet of Things), the upcoming communication standards such as LTE Cat-M2 heavily rely on the re-transmissions of the same data blocks. This represents an unique opportunity: The iterative Turbo equalization can already be performed in parallel to the actual data transmission. Thus, any additional latency contribution can be completely hidden making Turbo equalization a viable solution in practical communication systems.
Your first task in this project is to upgrade the available Matlab-based LTE-simulation environment to support a standard Turbo equalization algorithm. In a next step this algorithm needs to be adapted towards the LTE Cat-M2 physical communication channels which support codeword repetitions. In the next phase an architectural concept for a hardware implementation will be developed that especially needs to consider the synchronization of the channel equalizer and the channel decoder. Finally, you will port the algorithm to an HDL implementation and synthesize it either towards an FPGA or an ASIC implementation in order to analyze the hardware complexity of the developed algorithm.

 FAQS
 Q1. How can I find siblings in jQuery?
 The siblings() function is a built-in feature of jQuery that is used to locate all siblings elements of the currently chosen element. Siblings in the DOM Tree are those who share a parent element. The World Wide Web Consortium has established the DOM (Document Object Model) as a standard. This defines how to access items in the DOM tree.
 Q2. What is jQuery traversing method?
 In jQuery, traversing refers to travelling through or over the HTML components in order to locate, filter, or pick out a specific or all of them. It provides every descendant element of the chosen selection. between the supplied selection and parameters, it returns all ancestor elements.
 Q3. What is sibling in JavaScript?
 A sibling is a node that shares a parent (in the same childNodes list). Element Siblings are components that share a parent (in the same children list).
 Q4. What is the function of sibling?
 Siblings fill a special place in each other's lives that mimics both the influence and support of friends and the company of parents. Siblings are exposed to one another on a regular basis, much like other members of the immediate family, because they frequently grow up in the same home.
 Q5. What is sibling correlation?
 The sibling-correlation method calculates the proportion of overall inequality that may be attributed to things that siblings have in common. This percentage is typically much higher than what is indicated by estimates of intergenerational mobility.

text: Correction of myopia with the ArF-excimer laser (PRK) sometimes leads to a so called 'central island' formation on the anterior corneal surface. The attenuation of the laser beam by the ablation plume might be one reason for this phenomenon. The attenuation properties of the ablation plume were investigated by a probe beam parallel to the surface of the tissue probe. By varying the laser parameters (fluence, repetition rate, spot size) and the target tissue (cornea, PMMA) the attenuation of the probe beam was measured time and spatial resolved. As a result of this study, a significant influence of the removal process due to scattering and absorption within the ablation plume can be assumed as a function of repetition rate, spot size and air flow on the tissue surface.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.

Sea sponges have been used to soak up menstrual blood for decades. Much like a tampon, a sea sponge is inserted into the vaginal canal, where its super absorbency slurps up what your uterus is shedding. In fact, according to the Museum Of Menstruation and Women's Health:
Women have probably used sponges to absorb menstrual discharge for thousands of years, but they have also used them as contraceptives and for putting medication into the vagina (as with tampons; see hieroglyphics from about 1550 BCE). Sometimes it's hard to say which sponge was used for what - but maybe women sometimes used them for all three purposes.
So. Sea sponge: Not new. What is new? Calling it the Jam Sponge. As in jam it up in there? As in, what comes out looks like strawberry jam? Back to the drawing board with you.

HUNG KINGS' COMMEMORATION DAY - Back to The Roots of Our Cultural Values
On Saturday morning March 27, CIS students have visited the Hung Kings Temple at the History Ethnic and Cultural Park (district 9) with over 30 students and teachers from the Saturday Vietnamese Program onboard. Following the Hung Kings Temple, impressive performance, and others, students have been able to engage in a valuable learning experience. During the journey to the Hung Kings Temple, the students had the opportunity to participate in various activities and engage in a valuable learning experience.
Students were listening to a presentation at Hung King Temple
Here, they were able to expand their understanding of their origin as well as learn about the great contributions of the Hung Kings, accompanied by informative lectures. Also, there is an enormous artwork depicting the material and spiritual life of the residents in Van Lang's era, and 33 stones representing the 33 islands of the Truong Sa archipelago, which is a reminder of the awareness of the sea and island sovereignty.
Designing historical Hung Vuong period attire
Following the impressive performance, students soon got to shaping "bánh giày", which are round, white glutinous rice cakes, to recreate the traditional scene of hand pounding rice in the exploration of the 2875-258 BC Van Lang lifestyle
Students glutinous with rice and make bánh giày
Finish cooking of the Hung Vuong dynasty
The succeeding culture-themed games, including Cheraw dance and tug of war, kept spirits high until the end. By allowing students to interact with a part of Vietnam's history, these activities boosted their appreciation for Vietnamese tradition and culture, specifically during the Hung Vuong period.
Cheraw dance
"I can feel the value of Vietnamese history and our country's soul through each unique painting and ancient artifacts. That's what I want to learn and cultivate. I will bring my filial spirit to discover Vietnamese people's cultural values and beauty wherever I go to continue enriching my understanding. It is also luggage for me to bring in my future journey to a new horizon." (Minh Anh, Grade 11)
 At the end of the trip, students took a photo together
All journeys leave behind an unforgettable trace, and those aiming to instigate experience and newfound knowledge surrounding cultural values especially so. This occasion brings meaning and memorable experiences, particularly the students in grade 11 of CIS.

Thermal energy storage (TES) using phase change materials (PCMs) is being widely considered as one of the alternative solutions for effective use of solar energy. This paper presents a multi-objective optimisation strategy for TES systems using PCMs for solar air systems, in which two performance indicators of average heat transfer effectiveness and effective PCM charging time were used as the conflicting objectives. The influence of the key design variables on the performance of an air-based PCM TES system was first experimentally investigated using Taguchi method, and the results were used to develop two performance models for optimisation. A genetic algorithm was used to search for an optimal Pareto front and a multi-criteria decision-making process was employed to determine the compromise optimal solutions. The results showed that the average heat transfer effectiveness of the PCM TES system can be improved from 44.25 to 59.29% while the effective PCM charging time increased from 4.53 to 6.11 h when using the solutions identified by the proposed strategy with the weighting factors of 0.5/0.5 for both objectives, in comparison to a baseline case. A further comparison showed that the optimal design identified by the proposed strategy outperformed the two designs identified using Taguchi method.

The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The center of the pool is sterile due to extreme heat.
The deep blue color of the water in the center of the pool results from a light-absorbing overtone of the hydroxy stretch of water. Though this effect is responsible for making all large bodies of water blue, it is particularly intense in Grand Prismatic Spring because of the high purity and depth of the water in the middle of the spring.

JS constructor names make it easier to analyze memory dumps
As they say, "There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors". Out of these 2/3 things, naming is the most difficult. We all know that being lazy when naming things will hurt you down the road when you'll need to make sense of the code that you've written half a year ago. However, one more interesting aspect of good naming paying off I didn't previously think about is memory dump analysis.
Let's imagine, you are facing what looks like a memory leak or some strange behavior of the system and memory dump may help you understand what's happening inside the brain of your system in a particular environment. So you dump your heap, Google Chrome does a great job of grouping your object by constructor name, but all you see is this:
JS heap dump example with badly named constructors
Since your service classes where isolated in your modules/files and you default-exported them, it seemed unnecessary to think of fancy names. The path to the file identifies the service so well anyway! Not until you look at a heap dump like this.

In this experiment, high quality thin film acoustic devices were constructed utilizing zinc oxide (ZnO) thin film deposition, integrated circuit (IC), and electrochemical etch techniques. The bridge type ZnO thin film ultrasonic devices produced showed acute high frequency response sensitivity, with the high frequency response at 600 KHz attaining -124 dBV /spl mu/Bar. The highest response was near 8 MHz. Sensitivity increased in direct proportion to frequency, indicating that the bridge-type ZnO thin film acoustic devices were suitable for application as ultrasonic wave sensors at high operating frequencies. Further experimentation verified that the bridge-type ZnO thin film acoustic devices fabricated also had ultrasonic signal transmitting capability and signal bidirectional devices having both transmission and reception functions were successfully constructed. Therefore, bridge-type ZnO thin film acoustic devices will continue to be developed in the future due to the reliable control possible over the structural transformations involved; and, since IC fabrication techniques can be readily adopted in the process, the manufacturing of such devices will be greatly assisted.

Jiang Number Theory (JNT)
Authors: Laurent Schadeck
Jiang Chun-Xuan2 is a Chinese mathematician who claims to have developed new number theoretic tools consisting mostly in the Jiang function Jn (s #) where s # 2.3.5...p, p n denotes the primorial function to solve fundamental problems in Number Theory such as the Goldbach Conjecture, the Twin Prime Conjecture, the k-tuple Conjecture, and some other 600 basic prime number theorems. The fundamental motivation of Jiang to develop a number theory different from the one we are familiar with (we, number theorists) comes from his recent claim (1997) that the Riemann Hypothesis (RH) which lies at the foundations of all prime number theories, is false, that all calculations done to improve it are misunderstood, and that the entire speculative theory done through it (see Connes, Bombieri, Zagier et al.) are eventually uncertain.3 Our goal in this paper will be to review Jiang's achievements from his disproof of RH to his establishment of the new number theory.

Optical EngineeringToward an analog very large scale integration system for perceiving depth through motion parallax
|Format||Member Price||Non-Member Price|
|GOOD NEWS! Your organization subscribes to the SPIE Digital Library. You may be able to download this paper for free.||Check Access|
We describe the development of an analog very large scale integration (AVLSI) system for perceiving depth of a stationary object, termed the depth through motion parallax (DTMP) system. The system consists of an AVLSI smart focal plane array and an optical lens, with a laser system for the object. The DTMP integrated circuit is implemented using the AMI Semiconductor 1.5-µm process available through the MOSIS integrated circuit fabrication service. The DTMP chip and the lens are mounted on a single motion-controlled stage to mimic the human head and eye. The object is mounted on a different motion stage and is manually moved to different depths with respect to the lens. We report experimental results obtained for depth perception with the head being stationary and the object moving with a constant velocity that is geometrically equivalent to the object being stationary and the head moving with a constant velocity. Our results show that the transit time across the DTMP chip, which is equivalent to the perceived velocity, can be used to determine the depth of an object, and uses less than 2 mW of average power.

Hash House Harrier roots extend back to the old English schoolboy game of "Hares and Hounds," in which some players, called "hounds," chase others, called "hares," who have left a trail of paper scraps along their route across fields, hedges, streams, bogs, and hills. One of the earliest Hares and Hounds events on record was the "Crick Run" at Rugby School in Warwickshire, England, first held in 1837.
Hare and Hounds as an adult sport began in the fall of 1867 with a group of London oarsmen who wanted to keep fit during the winter. Also called "Paper Chasing" or the "Paper Chase," the game became very popular after its introduction on Wimbledon Common in 1868 by the Thames Hare and Hounds. Early clubs called themselves "Hare and Hounds" or simply "Harriers."
THE HASH IS BORN
The Hash House Harriers as we know it today was founded in Malaya (now Malaysia) by Albert Stephen Ignatius Gispert, an English chartered accountant. It was sometime during 1937 when Gispert (or simply "G" as he was known to his friends) acquired a taste for the paper chase with the Springgit Harriers in Malacca (also in Malaya). Shortly after being transferred by his accounting firm to Kuala Lumpur he gathered together a number of fellow expatriate businessmen to form a harrier group. The first run was held in in December 1938 and the founding members included Cecil H. Lee, Frederick "Horse" Thomson, Eric Galvin, H.M. Doig, and Ronald "Torch" Bennet.
The group's name came about primarily because local authorities required legal registration of the club. While the "Kuala Lumpur Harriers" would have appeared a logical choice, "G" decided instead to use the nickname for the Selangor Club where a number of the local harriers both lived and took their meals. It seems that due to its lackluster food, the dining room was commonly referred to as the "Hash House."
The philosophy of the original Hash House Harriers from the 1938 charter:
- To promote physical fitness among our members
- To get rid of weekend hangovers
- To acquire a good thirst and to satisfy it in beer
- To persuade the older members that they are not as old as they feel
Hashing in Kuala Lumpur was suspended during the World War II occupation by Japanese forces, but then reestablished after peace returned. It wasn't long before the hash began slowly spreading around the world. Former members of the original Hash House Harriers started a hash in 1947 near Milan, Italy, but it wasn't until 1962 that the next group was formed in Singapore. The Singapore Hash was gradually followed by others until in 1973 there were approximately 35 hashes in 14 countries.
Subsequently, the hash began spreading like wildfire and the number of hashes soon climbed into the hundreds by the early 1980s. Today (1999) there are some 1,700 active hashes in over 180 countries, including approximately 350 in the United States

Although rhodochrosite is found in many different localities, only a few supply the compact material which is used as an ornamental stone. It is commonly found in the form of stalactites and stalagmites in the caves of Argentina. Its use as an ornamental stone began just before the commencement of World War II, when a quantity of this stone came from San Luis in Argentina. The deposit from which it came was said to have been found in a long-disused mine situated on a mountain fissure at a high altitude, which was reputedly worked by the Incas for silver and copper during the thirteenth century. The Incas, who called it Inca Rose, believed that rhodochrosite is the blood of their former kings and queens / that was turned to stone.

How Do I Calculate Beam Size?
How do you find the width of a beam?
As per IS code 456 depth and width of beam depend on its length of beam and various types of load acting on it.
according to as per IS code 456 minimum depth of simply supported beam is about L/20 and minimum width of beam is about depth/1.5..
What is the maximum length of beam?
Span (distance) between two columns One can use beams of size 9″ X 12″ (225 MM x 300MM) with a slab thickness of 5″ (125 MM) cast in M20 concrete for spans up to 5m. There are other considerations like secondary and tertiary spans, point loads and wall loads which have to be considered.
What is depth of beam?
Introduction. A beam is considered as a deep beam when the ratio of effective span to overall depth is <2.0 for simply supported members. The beam theories which are based on assumptions are useful in case of those problems, where thickness of beams is moderate.
How far can a beam span without support?
What is the maximum length of cantilever beam?
That is the ratio of effective length to effective depth of the member. IS 456: 2000 prescribed a limiting value of 'l/d'=7, for cantilever beams for spans up to 10m. So, if we go beyond a certain length, we will end up with large depths as per the relation: d=l/7.
What is effective depth of beam?
For the design of the longitudinal tension reinforcement, the effective depth of a section, d is defined as the distance from the extreme concrete fibre in compression to the centre of gravity of the longitudinal tension reinforcement.
How much weight can a 2×12 beam hold?
How much weight can a 2×12 support horizontally? A 2×12 can withstand about 180 pounds per foot or about 2100 pounds.
What is the standard size of beam?
THE STANDARD SIZE OF THE BEAMS In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.
How do I calculate house beam size?
What is the minimum size of footing?
12 inchesThe minimum depth of footings below the surface of undisturbed soil, compacted fill material or controlled low strength material (CLSM) shall be 12 inches (305 mm). Where applicable, the requirements of CBC Section 1809.5 shall also be satisfied. The minimum width of footings shall be 12 inches (305 mm).
How far can a 2×8 beam span without support?
What is the minimum depth of beam?
How do you design a beam?
The design of concrete beam includes the estimation of cross section dimension and reinforcement area to resist applied loads. There are two approaches for the design of beams. Firstly, begin the design by selecting depth and width of the beam then compute reinforcement area.
How do you size a ridge beam?
Determining the Ridge Beam Height For example, if the slope is 4 in 12, and the run is 12 feet, the ridge beam height (M) will be 4 feet. The finished ridge beam height (Z) above the top of the wall will be (M) plus the Y Height. The formulas are: M = (R * X) / 12.
What size ridge beam do I need to span 20 feet?
If it is a 20′ span in the ridge beam you could easily need 3-18″ LVL's if not more and 18′ rafters will probably need to be 11 7/8's I joists.
How thick should a ridge beam be?
Ridge board shall be at least 1-inch (25 mm) nominal thickness and not less in depth than the cut end of the rafter.
What is a width?
The measurement of the extent of something from side to side. … Width is defined as the quality of being wide, or the measurement of distance from side to side. An example of width is a 36″ measurement for a table's wideness.
What is the minimum and maximum distance between two columns?
The Minimum Spacing or Distance between two column should not be less than 2.5 Meter. It Must be 2.5 Meter minimum distance. Or, Maximum Spacing & Distance of two Columns Should not be less than 7.5 meter.

Cast Iron Cistern Cover
Description: This is a metal cover for a cistern, or a large container (usually behind a house) used for storing and catching rainwater for use by people. It was made by the Sioux City Foundry and Boiler Company, one of the many different foundries that started here in Sioux City. Foundries are factories that produce metal castings. Liquid metal is poured into a mold and then cooled and removed from the mold, creating a cast. Cast metal, most commonly aluminum and iron, can be used to make metal items of many shapes and sizes, such as this circular cistern cover. Sioux City was a hotspot for foundries, even though the surrounding region contained very little iron and metal ores. Ore had to be imported from elsewhere, but cast metal was in such high demand in the industrial world many cities in the Midwest had foundries. Sioux City foundries were successful due to the city's shipping industry, which allowed for the transport of manufactured metal all across the U. S.
Sioux City Foundry and Boiler was originally Sioux City Foundry and Machine Works, started in 1871. In this time the company manufactured steam engines, machinery, pipes, fittings, and bolts in brass and iron. The company was also successful in producing machinery for steamboats and mills, as well as boiler works. Sales soared and the company expanded to a new warehouse in Leeds and changed its name: Sioux City Engine Works. Their new name shows their primary purpose: the manufacture of steam engines and their parts. They also produced a revolutionary furnace known as the Norfolk furnace, which was immensely popular. Sioux City Foundry and Boiler Company became the foundry's name in 1922, and this name lasted until 1963 when it was renamed simply Sioux City Foundry Company. The company still exists today in two plants: one for fabrication (working metal by cutting, bending, and welding) on Division Street and the true casting foundry in South Sioux City.

Rat Shooting Sport - Una nueva experiencia, un nuevo deporte. Tiro a la Rata.
© 2013 - RatShooting.com
 Exterminating common or sewer rats with fire arms as a leisure activity.
This is a new competitive sport that is a fusion of hunting an animal, which has a chance of survival, in a field, with the pertinent scoring provided by judges, together with the reflexes and calm required for competition target shooting, combined with stress relieving exercise, without forgetting about the health and environmental aspects
The main idea is to enjoy yourself in competition with others, without neglecting the aspect of controlling harmful rodents with a natural and effective method.
Individual or hunting in teams.
In the day-time version, the hunts are monitored by judges and they come to an end when all the rats have been eliminated from the field of action, or when they have got away through the holes made on the edge of the field for that purpose. If they do escape through the holes, they get into another area that is designed to catch and keep theme.
The judges count the animals shot and score the kills depending on the area of the field where they are shot. These zones are marked with the relevant scores before the hunt starts.
Important: There are different modalities for competitions between two teams, in a league, where there are sets of 5 hunts for each match. The winner is the team to win the best of the 5.
For individual tournaments, with everybody competing against everybody else, the winner of each match is the one that wins the best of three hunts and everybody carries their score forward until the end, when the final classification is decided on the number of hunts won and the number of animals killed.
The number of rats per hunt will depend on the organisation, championship or tournament.
Championships are played over a period of 6 months or more and tournaments can be one-day or weekend tournaments.
There is also a night-time version practised with infra-red goggles or under spot lights, using the same regulations as the day-time version.
Anybody with a firearms licence, or similar in the case of foreigners, may play.
The sport can be played as an individual or a team sport, depending on the rules governing each field.
For amateur or free hunters, both individuals and teams, the sets will be determined by the management of the field. The duration and price of the hunt will also vary, depending on the number of rats released into the field. The ideal number is 3 to 5 rats per player, all released at the same time.
I would like to call on everybody with a firearms licence, whether they have a gun or not, who takes part in other shooting sports or hunting to try this new exciting sport that has open season all year round at a very reasonable price.
The kind of gun of course, will depend on the legislation in force and the house rules of the shooting club or gallery, although several calibres can be used. The ammunition will be supplied by the shooting ground. Notice must be given of any special calibres. Comfortable clothing is recommendable.
The Management of the shooting grounds will require every participant or shooter to identify him/her self.
Held in an authorised and licensed shooting grounds, players may bring their own private guns, or they may hire a weapon from the club's armoury.
The hunting ground shall have a diameter of between 40 and 50 metres and marked with concentric rings worth different scores, like a target.
We are mainly interested in people with a communicative profile and team spirit who like extreme nature activities.
When you first come into this activity, you will be given a series of lectures/talks to ensure that the grounds operate properly.
An essential part of the training is to study the rat in depth to prevent any problems as this is team work.
The Staff of the grounds will work full time, but there may be free lance workers too, like the rat suppliers (trappers).
"Trappers": bearing in mind the large number of specimens required, this could be a well paid and interesting job for many people or companies. Trappers will be given a short training course to enable them to do their job.


Create a simple authentication used by a smartphone app with a cakephp webservice
Everybody is using smartphones to get there information on the go. To provide the necessary information there a several ways to do so, e.g.:
 - your usual web page
 - your usual web page with a special mobile layout
 - a native smartphone app retrieving its information via a provided web service.
In this post i take a closer look at the last point in a very simple way, which gives you an idea of how things can work and you can play around with.
For this simple approach the smartphone app needs to be able to store data on the device.
This is how the entire process works in my case:
The already registered User logs in via his smartphone app, which will send the username and password via post request to an url.
All the authentification happens on the website, so there will be no encryption done on the mobile device, which means there is no extra work to be done, when some thing on the webservice needs to be changed.
if username and password are correct the website will generate a token, saves it and send a response with either false or an array with the token and the encrypted password (i used the already encrypted password from database) that needs to be saved in the app.
From now on, the web service expects those values on every request and authenticates this device and therefor the user.
As long as this token is sent the app will be authenticated and on every login the token will be renwed for this user, which means that a login from another device will delete the current token and writes a new one that will be different. That means, that only one device can be logged in at the same time.
I started with a controller, that provides all necessary methods and will respond to a GET request with a JSON response.
I used the great and new CakeResponse (like shown in a previous post), which is the easiest way to answer the request without any special Views or echo responses from the controller.
Here is some example code which is used to get a forum thread by its database id. All other requests are pretty much straight forward like this one and keeping all logic on the webservices side.
public function thread($id = null) {
$data = array();
$data['Thread'] = $this->Forum->getThreadById($id);
return new CakeResponse(array('body' => json_encode($data, JSON_NUMERIC_CHECK)));
}
To this this point everything is pretty much basic stuff and i also assume you already have an Users table in your database with a username and an encrypted password.
I added a column "token" (varchar), "mobile_login" (datetime) and "android_registration_id" (varchar) into the Users table, this is where we store the hash thats authenticates the smartphone app at the web service.
You could use the "mobile_login"-date to check back on a regularly base and renew the token, if you see the need to do so.
The "android_registration_id" is used to save the google account id, which is used to send push messages through the website on the users phone, e.g. to send notifications if the user receives a a messages or something similar.
Therefore this is more on the surface of the subject, i think there will be more detailed posts about in the near future and i will be happy to get your suggestions how to improve or extend this approach.

Cocktail: What came first? | Bartender: Lachlan Robinson
The idea behind this drink is to create innovation through legacy, the legacy of those who have gone before. It is awkward to view the legacy of those great innovators that have gone before and decide that one can do better, but it is on the shoulders of those giants where modern innovation occurs. John Walker started the process for Johnnie Walker, but it was his son and grandson that would be the people to innovate Johnnie Walker, making it what it is today. The Johnnie Walker brand is the perfect example of legacy vs. innovation. I drew inspiration from the history of Johnnie Walker and how over the years sine the early 1800s they have released numerous expressions of whisky culminating in some of their limited release bottling's. One such limited bottling is the Johnnie Walker "Espresso Roast", the brainchild of blender Aimée Gibson and master blender Jim Beveridge. This whisky has huge coffee and chocolate notes not from the addition of coffee or chocolate, but purely born out of the roasting process. The barley used to make the "Espresso Roast" is roasted specifically to bring out the chocolate and coffee characteristics seen in the whisky. Whilst the legacy of Jonnie Walker is seen clearly in this product, there is also substantial innovation present.
The "Espresso Roast" and the innovation surrounding it led me to think about how bartenders use their ingredients. Are their more interesting or creative ways to use the ingredients we see every day? The method of production used for this whisky inspired me to look at ingredients and products more deeply, to see if I could utilize them differently. An obvious and highly overlooked ingredient is the egg.
What is an egg? The egg contains 4 parts, shell, membrane, whites and yolk. As bartenders we are known to use the white and the yolk regularly, but rarely, if ever, the shell or membrane. As I researched I happened upon the Chaud Froid egg leading me to discover the properties of the various parts. An egg has something that chefs have only just started to utilise for cooking, a semi permeable shell.
Looking through the legacy of classic whisky cocktails that use eggs I found inspiration. Eggs are mostly used as a textural element in a drink, adding creaminess or richness. Some have used the semi-permeable shell to infuse the egg yolk and white with other flavours. None, however, have used the shell as a vessel for a warm cocktail to be cooked in.
The What Came First is the cocktail spawned by the inspiration I had following the legacy of others. The hero of the drink is the Johnnie Walker "Espresso Roast". Bold notes of coffee, toffee, dark chocolate, and toasted malt are the foundations on which all other flavours are built on.
The "Espresso Roast" is married with Amer Picon and a Golden Beetroot and white chocolate liqueur. The Amer adds a herbal sweet bitterness, complementing the vanilla and chocolate notes of the "Espresso Roast" whilst the Golden beetroot and white chocolate liqueur adds a light vegetal, floral earthiness complementing the floral aroma and earthy palate notes of the coffee tones.
Vino Cotto, black walnut bitters and saline are added to balance. The vino cotto adds a sweet and sour element, rounding out the rich flavours of the drink and sending a sharp bite of acidity down the palate. Black walnut bitters add depth of flavour and nutty flavours complementing the flavours of the "Espresso Roast". Saline pares back the bitterness of the cocktail and carries some of the sweeter, lighter flavours to the front.
Chocolate tea is added to lengthen the drink, bringing down the alcohol content making the drink palatable, without losing or diluting flavour.
Finally an egg yolk is added, for texture and palate weight.
All these ingredients are added to the hollowed shell of the egg used for its yolk. They are then sat in a Sous-Vide for 2 hours at 48 degrees Celsius, in honey water. The drink is warmed as the honey water permeates the shell and infuses into the drink. This cooking process adds a warm sweetness and a rich velvety texture to the drink.
Served warm in a double walled coffee glass, shaped distinctly like an egg with no lid, the drink is topped with a lemon, white chocolate and beetroot foam, created with the whites of the egg. This foam adds the cold element to this drink giving juxtaposition in both texture and temperature. The lemon and liqueur add acidity, pleasant aroma and carry the flavours of the warm component of the drink.
Finally, as homage to Alain Passard's Arpège Egg the foam is topped with a chiffonnade of chocolate mint. The green fresh aroma from the mint, along with the aroma of the foam, brightens the deep, rich flavours of the drink. The chocolate mint also adds colour contrast, along with the foam, to make the drink visually appealing. The clear double walled glass allows this to be achieved as well.
This drink pays respect to the legacy of those who have innovated before us. Old techniques are used to create familiar flavours and textures. However, the inspiration garnered from those who gave us these techniques led to new, interesting and innovative techniques to be used to showcase new flavours or flavours used in a manner yet unseen. The Johnnie Walker "Espresso Roast" is the perfect example of innovating with what you have in front of you, using some everyday thing differently for a completely different result. This is what is achieved in the What Came First.

With modern techniques for nanoscale investigations, we are now exploring the interactions of clay minerals and human pathogens to learn the lessons that Mother Nature has used for healing. The vast surface area and chemical variability of hydrothermally altered bentonites may provide a natural pharmacy of antibacterial agents.

How to draw the quad entirely depends on what you're trying to do. If you want to fill the entire window with a glow texture, a 2D ortho projection makes that easy. Equivalently, the identity projection matrix, with a quad sized to the unit square [-1, 1] will also fill the entire viewport.
Sizing the texture, taking into account aspect ratio etc, is something you'll need to experiment with to see what resolution ratio between window/offscreen is acceptable.
Multisampling does not work with textures, but EXT_framebuffer_multisample will let you create a multisample renderbuffer. You have to explicitly perform the downsample resolve using EXT_framebuffer_blit. These are fairly new extensions, and aren't supported on all hardware. An alternative way to get multisampled render-to-texture is to use NSOpenGLContext's createTexture:fromView:internalFormat: method. That will give you a texture from the view attached to the context, based on whatever pixel format the context is using, including multisampling. It will implicitly do the resolve for you, like regular multisampling. And it works on all renderers that support multisampling (which sadly, doesn't include the Intel GMA renderers in MacBooks/iMacs/Minis.)
If you need some sort of antialiasing even on renderers that don't support multisampling, you can do your own supersampling, by rendering to a texture 2x larger than your target size and then drawing it with linear filtering. You can also mix this technique with regular multisampling, to get more than the 4 or 8 samples the hardware supports.

Is a Self Retracting Lifeline the same thing as a Yoyo?
Yo-yo, self-retracting lifeline, self-retracting lanyard, retracts, self-retracting devices, retractable lifelines…. The names for these lifesavers create a long and ever changing list depending on what region you're from and what industry you work in. What you really need to know is that, yes, they are all referring to the same device. A lifeline that pays out, retracts, causes deceleration, and arrests as a fall occurs is classified as a retractable lifeline.
What is a Retractable Lifeline?
Yo-yos are a type of lanyard that allow the user to freely move around the workspace as the lifeline cable extends out of the housing and, in turn, coils back up inside the shell as the worker gets closer to the unit again to keep the cable taut. This automatic feature eliminates the trip hazard commonly presented by a traditional lanyard.
How Does a Retract Work?
Self-retracting lifelines are devices that are connected to a worker's body harness. If a fall occurs, the deceleration device can detect the fall and engages an automatic break to stop the lifeline from moving, thus arresting the fall. The braking mechanism is similar to that of a seatbelt because if you yank on the lifeline, it engages the brake, but if you smoothly pull the line in and out, it creates a fluid movement.
Overhead and Horizontal Use of Self-Retracting Lifelines
Retractable lifelines can certainly be used in a number of applications and positions. For use overhead, the retractable almost instantly arrests a fall and drastically minimizes fall distance. Along with limiting fall distance, when the unit is anchored directly over the worker's head, the possibility of a dangerous swing fall is significantly lowered.
Using SRL's horizontally presents two very important factors to be weary of, leading edges and fall clearance. If you are using the retractable lifeline in conjunction with a horizontal lifeline or have the potential to encounter a leading edge, you must use a specifically engineered leading edge SRL to ensure the cable won't snap if a fall occurs. The other notable factor to look out for is calculating fall clearance. When the user is anchored off at foot-level and using a self-retracting device, it will take longer for the unit to detect a fall. Because of this, you must carefully consider the fall clearance needed before you choose an anchorage position.
OSHA and ANSI SRL Standards
OSHA has created standards for the personal fall arrest system to regulate equipment to comply with the arresting forces that the human body can withstand. In OSHA standard 1910.140(d)(1)(i) it reads that the PFAS should, "Limit the maximum arresting force on the employee to 1,800 pounds (8 kN)". The deceleration device (SRL or shock absorbing lanyard) satisfies this regulation.
The Occupational Safety and Health Administration (OSHA) standard 1910.140 states that "Self-retracting lifeline/lanyard means a deceleration device containing a drum-wound line that can be slowly extracted from, or retracted onto, the drum under slight tension during normal movement by the employee. At the onset of a fall, the device automatically locks the drum and arrests the fall."
ANSI furthers the regulations for retracts and states that the manufacturer of your SRL should have the deceleration information clearly marked on the front or rear label of the lifeline housing.
 1. Connectors – Connectors are any device that connects your body harness to an anchor point (e.g. shock absorbing lanyards, lifelines, self-retracting lifelines (SRLs), and positioning devices). Account for potential fall distance when choosing a type of connecting device. Adding/using shock absorbing lanyards reduces the fall force impact on your body.
 1. Deceleration Device – Any mechanism that serves to dissipate energy during a fall. Suspension trauma can occur in as little as 15 minutes; do you have a rescue plan?
 Have a fall protection question?

The approval of Magnetom Terra more than doubles the maximum MRI strength in the field.
The first 7 tesla (7T) magnetic resonance imaging (MRI) device has been approved by the US Food and Drug Administration (FDA).
The approval of Magentom Terra, a 7T MRI system designed by Siemens Medical Solutions Inc., more than doubles the available magnetic field strength for use in the US. Its approval was based on comparisons to a predicate device and sample clinical images.
Prior to its approval, the greatest approved field strengths for magnet fields measured by tesla were 3T MRI scanners.
The Magnetom Terra was reviewed by the FDA through a 510(k) premarket submission, intended to demonstrate substantial equivalence between a new device and legally marketed predicate device.
The FDA also reviewed radiofrequency subsystem safety, as well as comparative study data of 35 patients to undergo imaging under the 7T device and a 3T device. The 7T-acquired images were of diagnostic quality, according to board-certified radiologists who reviewed the comparison, and was an improvement from 3T imaging in some cases.
"The overall image quality of MRI improves with higher magnetic field strength," Robert Ochs, PhD, director of the Division of Radiological Health in the FDA's Center for Devices and Radiological Health, said. "The added field strength allows for better visualization of smaller structures and subtle pathologies that may improve disease diagnosis."
The Magnetom Terra is designated for patients who weigh 66 pounds or more, and is limited to extremity examinations.


700-Kilometer Megaflash Sets New Lightning World Record
Lightning over Porto Alegre, Brazil. Thiago B Trevisan/Shutterstock
The World Meteorological Organization (WMO) has confirmed a phenomenal lightning strike that split the sky in Brazil in 2018 has set the new world record for the longest lightning bolt.
Reaching 709 kilometers (440 miles) long – about the distance from New York to Charleston, WV – the "world's greatest extent for a single lightning flash" was recorded on October 31, 2018, in southern Brazil, the WMO's Committee on Weather and Climate Extremes announced.
That wasn't the only flashy record-breaker the UN's weather agency announced though. The record for the longest duration of a lightning flash got smashed too, thanks to a 16.7-second-long "megaflash" that occurred over northern Argentina on March 4, 2019.
Both new records have wiped the floor with the previous record-holders by more than double. The previous distance record was 321 kilometers (199 miles) recorded in Oklahoma in 2007, and the duration record was a mere 7.74 seconds over Provence-Alpes-Côte d'Azur, France, in August 2012.
"These are extraordinary records from single lightning flash events," said Professor Randall Cerveny, chief rapporteur of Weather and Climate Extremes for WMO, and co-author of the study confirming these findings in Geophysical Research Letters. "Environmental extremes are living measurements of what nature is capable, as well as scientific progress in being able to make such assessments. It is likely that even greater extremes still exist, and that we will be able to observe them as lightning detection technology improves."

Previously, lightning was tracked using data from ground-based sensors called Lightning Mapping Array networks, which detect radio waves. However, lightning scientists acknowledged there was an upper limit to the scale of lightning that could be traced using these, and tracking more extreme lightning would require a scale-up of the technology.
In 2016, the US National Oceanic and Atmospheric Administration (NOAA) launched the world's first lightning-mapping satellite to operate in geostationary orbit, tracking Earth's weather from 36,000 kilometers (22,300 miles) above us. This means that not only can we monitor Earth's weather 24/7, but as increased lightning activity is usually a good indicator of tropical cyclones and thunderstorms, forecasters now get a more accurate idea of what's coming.
It was this lightning-mapping tool, operating on the Geostationary Operational Environmental Satellites (GOES), that recorded the two new records.
Satellite image of record duration of a lightning flash, Argentina, March 4, 2019. WMO
There are many different types of lightning. Lightning always accompanies thunder and they both happen at the same time, but as light travels faster you often see the lightning before you hear the thunder. Most lightning starts within a thunder cloud and then either stays in the cloud or travels through air, either to another cloud or to eventually hit the ground. Both record-breaking flashes occurred from cloud to cloud, without touching the ground, but why were they so powerful?
There are two hotspots in the Americas where mesoscale convection systems – thunderstorms that combine into large clusters, or "superstorms" – form: the Great Plains in North America and La Plata basin in South America. These superstorms occur on a scale that allows for extraordinary megaflashes. Now that we have the technology to monitor and observe these megaflashes, it's highly unlikely these new records will stand for long though.

Caves in SlovakiaIn Slovakia there are about 4 thousand caves, 14 of which are open to the public. Usually these caves are with stalactites, several are the ice caves.
There are also very special and rare caves, like the Ochtinska Aragonite Cave, that is one of the three accessible caves of this kind all over the world.
The underground spaces of these caves were created during millions of years thanks to the continuous intense activity of water, of rocks and of air. The calcareous formations that come down from the ceiling are called stalactites. If this formations raise from land are called stalagmites, while when such formations meet themselves are called columns.
Caves in SlovakiaThe color of these formations depends on the different mining structure of the rocks. The iron confer to the rocks a yellow color, rose and even red, the manganese from a grey color, grey-dark blue, to a black one, while the stalactites bleaches contain carbon calcium.
All the accessible caves are also used for the care of allergic and relevant illnesses and respiratory diseases.In some caves, thanks to the high dampness, it is put into practice the speleotherapy for the children.
What is speleotherapy - speleotherapy is practised, mostly for children with breathing difficulties. The basic procedure of speleotherapy is a stay in the cave accompanied with activities increasing the effect of aerosol. Speleotherapy, that originally belonged to the group of people's empirical methods of cure, has now overcome a barrier of ignorance and distrust, and is definitely ranked among effective ways of treatment.
Caves in Slovakia In 1995 was added to the UNESCO World Heritage List, together with the the Ochtinska Aragonit Cave, also other the 4 caves of the Slovak Karst - the Domica Cave, the Silicka ladnica Cave (Slilicka ladnica), the Gombasek Cave (Gombasecka jaskyna) and the Jasovska Cave (Jasovska jaskyna). In 2000, it was added to this list the Dobsinska Ice Cave.

On 29 November, the United Nations Volunteers (UNV) programme in Fiji launched a flagship report, the State of the World's Volunteerism Report (SWVR) 2018, demonstrating that volunteers across Asia and the Pacific region are a fundamental coping strategy for resilient communities. The SWVR 2018 launch in Suva, Fiji was held on the occasion of the UNV Executive Coordinator's official visit to the Pacific.
As our climate changes rapidly, it brings major new risks for communities. Across all societies, volunteers are at the forefront of responding to and coping with shocks, using local knowledge, networks, and capacities to build community resilience. But the scale and unpredictability of future risks, rising inequalities, and low capacities mean that new support is required to sustain this people-centred approach to climate resilience. The Policy Brief acknowledges how volunteers are already mapping and monitoring climate change at scale.
UNV commissioned this global research study to provide a picture of trends and lessons in the development of supportive volunteerism policies and legislation in the decade of volunteering from 2001. A review was conducted in seven regions, complemented by country-specific case studies in each region. The study analyses considerations in drafting and implementing volunteerism laws and policies, and highlights the need to tailor them to specific local, national and regional contexts. This paper is currently being updated for the 2018 State of the World's Volunteerism Report.

Industrial Keratinase Enzyme for Cosmetics Skincare Leather softening
Keratinase is a kind of protease with broad specificity capable of degrading water soluble and insoluble proteins.It has disulfide bond reductase and peptide hydrolysis enzyme activity,and can effectively catalyze the hydrolysis of proteins especially keratin proteins, can be widely used in feed, leather, food, cosmetics, and other industrial fields.
Keratin is commonly found in fur, feather, horn, hoof and fish scale. It contains high amount of cross-linked disulfide bonds and hydrophobic amino acids forming very tight structure, and is very resistant to proteolysis. Keratinase is unique in that it contains multifunctional potent enzymatic activities attacking disulfide links and peptide bonds, and thus depolymerizes keratin efficiently, increasing digestibility of feed containing protein with the similar structure.
Definition of Keratinase Activity
One unit (U) of keratinase activity is defined as the amount of enzyme which liberates 1 μg tyrosine per minute from substrate casein at pH 10.5 and 40℃.

GTViewer's Upstream/Downstream Trace Application - Part 1
The Upstream/Downstream Trace began as a demo app to show off the Tracing capabilities of GTViewer, but it has evolved into a very sophisticated analysis application. The Upstream/Downstream Trace's original goal was to show the user all of the upstream features (along the path back to the breaker at the substation) and all of the downstream features (along the opposite path to the breaker). Now, the application allows the user to change the status of any switchable device (fuse, switch, etc.) and immediately see how it affects the flow of electricity in the network. This Blog posting will cover all of the features of the Upstream/Downstream Trace application to show one example of how GTViewer can be used as a platform for developing GIS applications as well as being an excellent viewer.
GTViewer's Tracing capability works for many different kinds of data. For Intergraph data (Framme or G/Technology), the database table storing connectivity information is used. For Smallworld and ESRI data where connectivity is stored as coincident graphics, GTViewer's spatial indexing mechanism blazes through the graphics to find connected features. GTViewer's tracing capabilities are augmented by GT/Trace which is a development tool that encapsulates all of the commonalities found in network tracing. GT/Trace accelerates the development of network tracing application and maintains a solid and well tested framework for network Tracing applications.
Running the Upstream/Downstream Trace is as simple as picking it from the menu in GTViewer. You will immediately see the dialog shown below:
When the Trace app is activated, it will wait for the user to select a starting feature. This feature can be limited to conductors, primary features, or any feature that carries electricity. This example limits the user to selecting primary conductor as the starting feature. By simply clicking on a primary conductor, the trace is started.
The Upstream/Downstream Trace's dialog has several buttons and options at the top. The Reset button will clear any previous trace information and put GTViewer back into select starting feature mode. The Cancel button will stop a trace if it has already begun; this button is disabled if a trace is not actually running. The Locate Start button is provided to find the trace's starting feature. Since the trace results are fit when the trace is completed, it is sometimes useful to easily and quickly go back to the starting feature. The Fit Trace button is provided to fit the trace results at any time. If you zoomed into look at features in the trace results more closely, or used the Locate Start button, the Fit Trace button will immediately fit the entire trace's results into the current view.
Several options are also available to govern how the trace is run. The Search For group of options allows the search to run in three different modes: Upstream, Downstream, or Both. While this is an Upstream/Downstream Trace, the user may only be interested in the Upstream features or the Downstream features. If this is the case, the time needed to trace in both directions is sometimes not necessary. If the network does not support some form of directionality in its connectivity data, the trace will have to search to find the breaker at the substation to know which direction is upstream, so if the direction traced first is not the desired direction (when only upstream or downstream is selected), the trace will have to search in the other direction as well. Fortunately, the GTViewer's tracing process is very fast and the selection of just Upstream or just Downstream is more for configuring the Trace results than increasing performance.
Three more trace options are also provided as checkboxes:
 - Highlight While Tracing is usually turned on so that the tracing can be seen while it is being performed. While this option does slow down the tracing process, GTViewer is very fast displaying graphics and it is unlike most traces you have seen before. Since the trace results are constantly being fit to the view, the view zooms out as the trace progresses resulting in a "mesmerizing" effect (possibly something you have to see to fully understand this description). It is far from the ka-chunk-ka-chunk one feature at a time highlighting I have seen with other GIS systems (not viewers). How much this option actually slows down the tracing process is dependent on many variables but usually in the area of 30% to 50%. Again, GTViewer's tracing is very fast and most users prefer to watch the highlighting as it progresses.
 - Include Secondary is an option to trace secondary features such as Secondary Conductors and Secondary Meters. Some GIS data does not include secondary features in their connectivity model, so this is not always an option. The secondary information may or may not be of interest to the user and turning it off will declutter the results and increase performance (since there will be fewer features to trace).
 - Automatically Clear Highlight is an option that is usually turned on. It will reset any previous trace results in the view when a new trace is begun. If you want to see multiple trace results together, then you will need to turn this option off. You can also clear the trace results at any time with the Refresh button on GTViewer's toolbar.
The following screenshots show a sample trace. The first screenshot has the raster backdrop turned on and the second one is shown against the overview graphics. In both screenshots, the following rules apply:
 - Magenta is the Starting Feature
 - Blue is Downstream
 - Red is Upstream
 - Yellow Circle is the location of the Breaker
Raster Backdrop:
Overview Map as Backdrop:
The Emphasize Session Graphics mode is automatically turned on when a trace is completed so that the Trace results are clearly visible against the rest of the data. If we zoom in to the area around the breaker (Yellow Circle), you can still see the trace results very clearly against the grayed out features.
The Upstream/Downstream Trace Dialog also shows a status window to indicate what is going on with the trace. When the trace is successful, it shows how many features are in each path, the path where the breaker was found, and the time it took to perform the trace. If there were errors or if the trace were canceled, the status window would also show this information. The Feature and Node labels at the top of the status window give you an indication of how the trace is progressing. The Feature count is the number of features traced. The Node count is the number of unprocessed nodes; this number will go up and down as the tracing progresses. As the trace nears completion, the Node count will go to zero and the trace will stop (as there are no more nodes to trace).
The Output list at the bottom of the Upstream/Downstream Trace Dialog shows a list of all features traced. This information includes the order of the features as they are traced, the trace path they belong to (upstream or downstream), the name of the feature, and the feature's keys. The results can also be copied to the Windows clipboard with the Copy button; these result can be pasted into Excel to make a report.. Also, if you click on one of the items in the list,
it will be located immediately in the view. See the following screenshots for an example.

Estonia studies mobile geolocation data to analyse movements
Estonia's Government Crisis Commission has instructed the state statistical office, Statistics Estonia, to use mobile geolocation data from companies such as Telia, Elisa, and Tele 2 in order to study people's movements to prevent the spread of COVID-19. Statistics Estonia hoped to launch the project during the week of March 24, 2020. Mart Mägi, the director general of Statistics Estonia, said the intention was to analyse people's movements before and after emergency measures were implemented, and that, if the telcos agreed it was feasible, data processing would take place only within Statistics Estonia's secure environment. The data protection inspectorate has agreed that this tracking is legitimate as long as the data is not personalised and it is used only for the purpose of providing generalised results.

The legislation, or the laws surrounding the keeping of these lizards, have not changed drastically over the last few years. The main questions I get asked often surrounds the keeping of Bearded dragons in specific provinces, i.e. the necessity of having a permit and importing Bearded dragons into South Africa.
The legislation surrounding Bearded dragons are the same for any exotic (i.e. those that are not naturally found in South Africa) animal species. This probably includes birds, fish etc. As of the late 1980's it is illegal to own any exotic reptile species that was not imported into the country by that time. Bearded dragons are one of those. They've been in the country before the prohibition of exotic importation of exotic species and are thus legal in South Africa.
I am not aware of any permit system incorporated in South Africa.
How do I import Bearded dragons into South Africa?
The legal importation of new Bearded dragons into South Africa is a different story. You will probably find no permits to do so making it, strictly speaking, illegal.
Is it legal to keep a Bearded dragon in my area?
Although Bearded dragons are a legal species in South Africa, they are illegal to keep in the Western Cape due to the strict protection on their fragile fauna and flora. The escape of one or two Bearded dragons into this highly evolved environment probably will put a lot of strain and danger on plants and other animal species.
I am not aware of any restrictions from other provinces.

Jumping into a better life: the profitable world of grasshopper rearing
A Surin couple are augmenting their teaching salaries by raising Patanga grasshoppers, also known as Bombay locusts, to sell their eggs and meat.
A kilogram of the grasshoppers goes for 450 baht, while the eggs can be sold for up to 10,000 baht per kg to other grasshopper farmers, said Somphong Cheuthong, 53, a teacher in Surin's Sang Kha district.
Grasshoppers are a Thai delicacy, often eaten fried and sprinkled with soy sauce as a snack. They are considered a future food due to their high protein and low fat, and can be farmed using agricultural remnants such as coconut coir and banana leaves, he said.
Somphong said he and his wife, Maneewan, 51, who is also a teacher, have long been trying to find second jobs to generate the income they need to cover the expenses of raising two young daughters. They have tried several career options in their free time including opening a coffee shop, raising cows, and growing grapes.
"None of these can compete with grasshoppers in terms of extra income," said Somphong, adding that he had started by researching on social media how to raise grasshoppers in his free time.
He bought 100 grams of grasshopper eggs for 1,000 baht, which can produce around 500 grasshoppers, and raised them in a homemade shed fashioned from mosquito netting measuring 3x4 metres and two metres in height. The ground must be covered with sand mixed with wet coconut coir, banana leaves or cut grass.
After spreading the eggs on the ground, all the farmer has to do is water them every morning and evening. The eggs will hatch and become adult grasshoppers, after which they will mate with each other and produce more eggs, which can be harvested every 2-3 days.
After 45 days, they will stop laying eggs. The farmer will then sell them for meat and start a new batch of eggs.
Maneewan said since they started a few months ago, the orders for grasshopper eggs and meat have been pouring in non-stop from local merchants and online customers, prompting her to build two more sheds to meet the demand.
She said most of her customers are fellow grasshopper farmers who need new batches of eggs for their cycle.
"Raising grasshoppers is a great part-time career with good income due to the high demand. Getting started is also easy and requires only a small investment," Somphong said. "Plus, the more people raise them, the more we can sell eggs, making it a sustainable business with a constant supply of customers."

This study uses household-level panel data on smallholder farmers in Ethiopia to estimate how rural population density (RPD) affects agricultural intensification and productivity. Our results suggest that higher RPD is associated with smaller farm sizes, and has a positive effect on input demand, represented by increased fertilizer use per hectare. Overall, increased input use does not lead to a corresponding increase in staple crop yields, and thus farm income declines as population density increases. This suggests a situation where farmers in areas of high RPD may be stuck in place, unable to sustainably intensify in the face of rising RPD and declining farm sizes.

Joint mobilization is the careful application of skilled forces to restore a dislocated joint. This may be as a result of extended or torn ligaments, muscles and tendons found on the joints. Joint mobilization addresses joint pain and joint stiffness. Physical therapists at Whites Physical Therapy use the following techniques to administer joint mobilization:
- Gentle joint mobilization
- Mobility exercises
- Minimal energy techniques
- Joint manipulation
- Physiotherapy instrument Mobilization
These techniques ensure successful treatment of joint pain and stiffness. Our adept physiotherapists apprehend your joints and can easily regain full joint range and relieve joint anguish during therapy.
Successful Treatment Options
Physical therapists in Wilmington, MA came up with the following treatment options that have increased the rate of recovery among patients:
- Early injury treatment
- Soft tissue massage
- Running analysis
Importance of Joint Mobilization
Joint mobilization relieves pain and releases strain from joints in the body. Sport-related injuries are also treated through regular joint mobilization. Physical therapy at White Physical Therapy has also proven to be effective in addressing movement impairment in patients with disabilities and the elderly. It is especially effective in the treatment of joints affected by arthritis. Joint mobilization consistently and progressively improves joint movement and joint assimilation of food for growth and maintenance whiling decreasing muscle spasms.
Joint mobilization safety
Joint mobilization is secure as it is done at a slow pace and one can ask the therapist to halt the process if any discomfort is experienced. Thorough evaluation of blood and nerve circulation, bone muscle movement is carried out before the actual mobilization procedure is started. This is beneficial as one is able to discover other abnormalities in the blood or nervous physiology that can be treated early. Overall, joint mobilization is a secure, amiable and effective method of physical therapy.

Song, Y.; Sun, X. Modeling and Dynamics of a MDOF Isolation System. Appl. Sci. 2017, 7, 393.
This study analyzes the modeling and dynamics of a novel passive in Multi-Degree-of-Freedom (MDOF) vibration isolation platform which can achieve significant isolation effect. Symmetrical Scissor-Like structures (SLSs) are utilized in the proposed MDOF isolation platform as the supporting and isolation elastic components. Based on the mathematical modeling and theoretical analysis of the MDOF vibration isolation system with SLSs, the effect of structural parameter and joint friction on stiffness and damping properties is investigated. It is shown that due to geometric relations within the SLSs, the natural frequencies can be reduced via adjusting structural parameters of the SLS for different direction vibration isolation. Theoretical and experimental results show that the SLS isolation platform can achieve much better loading capacity and vibration isolation performance simultaneously by only using linear passive components because of the MDOF adjustable stiffness property. Therefore, with low costing and energy consumption, the proposed novel isolation platform can provide the improvement of vibration suppression in various engineering practices.

Why become a Child'Space practitioner?
The way in which infants perceive, organise and process information directly affects the development of movement skills and the way they relate to their environment.
Monitoring and supporting an infant on this critical journey influences his physical, social, emotional and cultural adjustments throughout his life.
In recent years a growing number of children are requiring special education services, even as early as kindergarten.
Early intervention and stimulation of a child's primary developmental pathways can prevent or alleviate some of the manifestations of impaired development that many in our society are experiencing.
This is why we've developed a two-year training program to teach people to become an official Child'Space practitioner.
Manuel Reetz
Manuel Reetz Feldenkrais practitioner
As a Feldenkrais practitioner my daily business is movement. I thought, that I have a good understanding about movement and patterns. Child'Space offers for me a new point of view for movement. Babies are playing with gravity as a very new thing in their life. Grown-up persons know gravity, but have no awareness of it and of their patterns dealing with it.
So Child'Space is bringing me back to my roots and let me experience movement from a baby's point of view while playing with gravity. A very big adventure.
Child'Space graduates report that, in addition to their new professional skills of working with babies and parents/caregivers, the Training Program has deepened and broadened their understanding of the theoretical roots and structure of the Feldenkrais Method, improved their FI (Functional Integration/individual lessons) and ATM (Awareness Through Movement) skills, and sharpened their observation skills concerning the connection between movement, emotions and cognitive development.

It's a birders' paradise, one which gets avian visitors from far and wide. Over 60 species of migratory birds visit this bird sanctuary which is known for its avian wealth as well as unique topography.
The Kadalundi Bird Sanctuary in Kozhikode is spread over a cluster of islands and is hemmed in by hillocks. Come the migratory bird season, the area sees a heavy influx of birds and also birders. Seagulls, terns, sandpipers, sand plovers, and turnstones are just a few varieties of the birds that arrive during the birding season.
The ideal time to visit this sanctuary is between November and April when the place turns into a paradise, bustling with birds of different plumage. There is never a dull moment, as over 100 species of native birds dwell here.
From here, one can see the mouth of the Kadalundi as it drains into the Arabian Sea. Apart from birds it invites, the sanctuary is known for its marine wealth which includes fishes, crabs and mussels. The locale makes for a scenic escapade with its mangrove forests and other natural wonders. Other activities that may attract the traveller include trekking and photography. The climate is good for the most part of the year as it is located along the coast.

A Novel Surgical Technique For Closure of Dehiscence Conjunctiva Due to Glaucoma Drainage Device
 Channels: Glaucoma | Posted 9/27/2018
Our aim is to describe a novel surgical technique for dehiscence conjunctiva caused by glaucoma drainage devices not responsive to conventional closure methods. There has been a significant rise in the implementation of glaucoma drainage devices for the surgical treatment of glaucoma; this has required surgeons to deal with their many limitations. One common unwanted occurrence is the postoperative extrusion of such tubes or plates through eroded conjunctiva. This can have catastrophic implications and leaves this cohort of patients at high risk of endopthalmitis. There remains a significant paucity on guidance in literature best describing optimal surgical techniques when attempting to deal with this unwanted complication. We describe a modified technique successfully implemented by our institution achieving consistent outcomes in even the most complex cases. We describe a modified surgical method involving a combination of relieving conjunctival incisions, tutoplast, conjunctival autograft, and amniotic membrane. We illustrate its implementation on a case example in a patient with a complex ocular history including, keratouveitis, dry eyes, and previous Baerveldt tube insertion presenting with externalization of plate. A combined surgical closure method should be adopted in complex cases when failure of direct closure will almost be inevitable.

text: This paper explores the problem of determining the success of students in higher engineering programmes. The best way to do this is a full cohort analysis, which yields information such as throughput rates, average time to graduation and average student years per graduate. A much cruder measure is graduates/headcount, the inverse of which is similar to average student years per graduate. The paper proposes an alternative to a full cohort analysis which looks back from graduation to predict the same parameters. These analyses are compared using data for a fouryear engineering programme. The results clearly show the shortcomings of the headcount analysis, as well as the potential of the looking back analysis, especially where large sets of data are concerned. The paper also indicates the value of determining the number of student years it take to generate a single graduate, in terms of the funding which needs to be provided.
