NASA helps launch Angry Birds Space game
Looking for ways to attract new audiences to its space and technology mission a year ago, NASA saw a prime opportunity to fly with some hugely popular birds.
And now the results of NASA's innovative collaboration with mobile game company Rovio Entertainment is approaching lift-off: the Angry Birds Space game created by Rovio with NASA's cooperation debuts on March 22.
Angry Birds is one of the most popular mobile games ever, with the company claiming more than 500 million downloads in two years. Originally created on iPhone, it is also available for Android and other devices. In the game, stylized cartoon birds are launched to destroy pigs.
"The value [of the collaboration] for NASA is in getting people excited about science and space technology," Bob Jacobs, a NASA spokesman, told Federal Computer Week on March 13. 'This could be an important tool to reach new communities. We saw the possibility of reaching a very different audience through a gaming platform," Jacobs said.
In the original game, the player launches the angry birds with a catapult to destroy the structures in which the pigs are hiding. The game reflects the laws of physics, so the player can change the angle and power of the catapult to change the trajectory of the bird.
The new space version of the game applies the laws of physics that exist in outer space. Rovio designers met with NASA engineers to develop ways to demonstrate zero gravity principles in movements within the game. The game also contains a permanent Web link to a NASA website on zero gravity, also known as microgravity.
The collaboration is generating a lot of interest. A jointly-produced video featuring NASA astronaut Don Pettit at the International Space Station has already received more than 4 million views on YouTube. In the video, Pettit demonstrates zero gravity principles in action with a stuffed bird resembling the Angry Red Bird character.
Rovio and NASA debuted the introductory video on March 8 at the South by Southwest conference in Austin, Tex. Pettit can be seen in the video talking about gravity while floating around the station and shooting one of the stuffed birds down a tunnel with the help of a slingshot.
It all started with a tweet
The project started a year ago when Jacobs noticed several tweets mentioning NASA and Angry Birds. "NASA launched a man to the moon. We launch birds into pigs," read a tweet from game consultant George Bray.
There also were tweets circulating about smart phones today allegedly having more computing power than NASA computers back in the 1960s, Jacobs recalled.
Jacobs responded through the _USER_ Twitter account he manages. "Hey, RovioMobile, our computers are a bit better than they were in '69. We might be able to help you launch birds if you can find a pig in space," Jacobs tweeted on March 27, 2011.
Rovio also responded, and a conversation began. "It started with a tweet," Jacobs said. "It sparked a lot of light bulbs going off in people's minds."
The collaboration took off from there, with NASA and Rovio signing a "Space Act Agreement" outlining the terms of the collaboration with Rovio, which is from Finland. The federal agency has many such agreements in which it cooperates with private sector projects, Jacobs said. For example, NASA previously had signed an agreement with Paramount Pictures for allowing the filming of a Transformers movie at the Kennedy Space Center. All such agreements are vetted by NASA management to ensure they comply with regulations.
One of the initial fruits of the NASA-Rovio effort was that a version of Angry Birds released in 2011 had an "outer space" level embedded in it. Rovio debuted that version to coincide with the final space station launch, and the company distributed tee-shirts and other publicity materials.
There are no financial terms in the agreement with Rovio, Jacobs said. NASA has no mechanism to receive funding for such efforts, he added.
Jacobs said the collaboration has been successful, because the goal is to reach new communities, including millions of people likely to play Angry Birds Space.
"We see it as a mutually beneficial relationship that allows us to get NASA mission information into the game," Jacobs said. But he acknowledged that measuring the success of the endeavor might be a bit tricky.
For example, Rovio's YouTube video on the NASA Angry Birds Space announcement has received more than 4 million views. Meanwhile, the NASATelevision version of the introductory video has received only about 38,000 views.
On the other hand, Jacobs said many people have tweeted about, and shared links to, both videos on social websites including Facebook, Google+ and Twitter. NASA is gaining value from that sharing even when people view the video at Rovio's YouTube page rather than NASA's, he asserted, because the people are being exposed to the same principles of science and technology regardless.
"Having a bird and pigs in space are fun and cool ideas," Jacobs said. "We are seeing communities getting excited about it and sharing the information."

Sox is based on my Korean cultural heritage influenced by attitudes in the USA. The artworks look like cute Valentine's Day socks, but these typical American holiday icons, a bear, a heart, and a green frog, actually refer to individual Korean myths and cultural stereotypes.
In "Which Part of NO Don't You Understand?" the text is combined with the image of a heart. It is based on a sentimental Valentine's day cheesiness which contrasts with a New York, street smart, feminist attitude.
In "What Is My Social Responsibility As A Korean Artist?" the text of the work's title is combined with the image of a teddy bear. It attempts to question the fundamental roll of an artist in society which contrasts with the simple and cartoonish visuals.
It is based on the Korean myth of the "Tale of Tangun," which explains the origin of Korean women and Korean culture. According to this myth a bear became the first Korean women by praying and eating only garlic for 100 days in a cave. The cute teddy bear is a reference to this myth. This work explores what it means to be a Korean woman artist in the cultural mix of the present.
In "Why Do You Have To Be A Green Frog?" the text is combined with the image of a cartoon frog. The text is an English translation of a common Korean phrase which means "why do you have to be a rebel?" and is very similar to the American idea of being a "black sheep" – somebody who is different and doesn't fit in with the crowd. It is also something that my mom used to tell me.
In the west, a green frog represents romance, like the frog who when kissed, turns into a prince. In Korea, a green frog is rare and considered to be bad luck if you catch it or kill it. It appears in a Korean children's story where the green frog gets into trouble by not obeying his parents. Korean children are supposed to learn a lesson about the value of obedience and conformity from this story.
Sox explores the interplay between globalized mass commercial production and contemporary art practice by using traditional Korean icons that are reinterpreted as American Hallmark style designs.

Main Article Content
The need for a multidimensional measure of population health that accounts for its distribution remains a central problem to guide the allocation of limited resources. Absolute proxy measures, like the infant mortality rate (IMR), are limited because they ignore inequality and spatial clustering. We propose a novel, three-part, multidimensional mortality indicator that can be used as the first step to differentiate interventions in a region or country. The three-part indicator (MortalityABC index) combines absolute mortality rate, the Theil Index to calculate mortality inequality and the Getis-Ord G statistic to determine the degree of spatial clustering. The analysis utilises global sub-national IMR data to empirically illustrate the proposed indicator. The three-part indicator is mapped globally to display regional/country variation and further highlight its potential application. Developing countries (e.g. in sub-Saharan Africa) display high levels of absolute mortality as well as variable mortality inequality with evidence of spatial clustering within certain sub-national units ("hotspots"). Although greater inequality is observed outside developed regions, high mortality inequality and spatial clustering are common in both developed and developing countries. Significant positive correlation was observed between the degree of spatial clustering and absolute mortality. The proposed multidimensional indicator should prove useful for spatial allocation of healthcare resources within a country, because it can prompt a wide range of policy options and prioritise high-risk areas. The new indicator demonstrates the inadequacy of IMR as a single measure of population health, and it can also be adapted to lower administrative levels within a country and other population health measures.

REGIONAL: A deep-dive into the impact of COVID-19 on tourism and long-term implications for international travel
The impact of the coronavirus (COVID-19) pandemic has had a significant impact on Europe's tourism industry. As governments are struggling to convince citizens that national outbreaks have come under control, the outlook for international travel remains bleak.
According to data from the World Tourism Organization (UNWTO), there was a 98 per cent fall in international tourist numbers in May compared to the same period last year. This essentially equates to a drop of around 300 million tourists and a revenue loss of approximately USD320 billion, globally. The EU tourism industry employs around 13 million people, and an estimated EUR1 bn per month is being lost. In Italy, the Italian tourism federation estimates that around 60 per cent of tourists will be lost this year. Globally, 75 million jobs could be lost, including 6.4 million in the EU, according to the World Travel and Tourism Council (WTTC). A series of major sporting and cultural events, including the UEFA Euro 2020, usually a magnet for overseas tourists, have also been cancelled or postponed to 2021.
A key obstacle to the resumption of normal tourism flows is the current border situation in Europe. For instance, Hungary announced in late August that from 1 September it would shut borders to foreign nationals, essentially marking a return to the travel restrictions imposed to cope with the first wave of coronavirus. The ban will remain in place for at least one month, and Hungarian citizens have been urged to avoid non-essential travel to other countries. This makes Hungary the first Schengen Area member to re-introduce a ban, while most other EU countries have opted to avoid similar action. More broadly, it signifies that there remains scope for divergence in approaches from EU countries despite an incohesive and inconsistent approach in the early stages of the pandemic. Indeed, travel has become an increasingly complex undertaking, with passengers required to complete multiple forms in addition to completing COVID-19 tests before departure. Another key concern for tourists is the requirement for arrivals to undergo a two-week quarantine.
Given the severe sectoral impact of the pandemic, the EU has sought to alleviate some economic pressure on the tourism industry. Unprecedented levels of economic uncertainty will mean less disposable income for leisure travel. The majority of EU member states have announced plans to introduce economic assistance packages, including tax moratoriums and wage subsidies, that will also cover the tourism sector. In the wake of the pandemic, state intervention in private markets will become the norm. This has already been seen through the full acquisition of Alitalia by the Italian state and the partial nationalisation of railways in the UK.
The lack of a vaccine or effective treatment will continue to present longer term challenges for the sector's recovery. For companies with staff travelling regularly for business purposes, operational resilience plans will have to adapt to new realities. Business travellers for instance should ensure they travel with all the necessary documentation and ensure they carry a 'COVID kit', which will comprise of hand sanitiser, face masks, and disposable gloves. Effective planning can be helped by travel risk teams proactively monitoring communications for any new restrictions at destination or transit countries.
Ultimately, the traditional tourism model will undergo a profound shift. In the current context and the near future, a new important condition for tourists before beginning travel will likely be the performance of a government in dealing with national outbreaks. More travellers will pay closer attention to the quality and standard of healthcare in destinations. Countries that recorded comparatively high infection rates will likely suffer more than others with similar climates and tourism infrastructure. Rural destinations in normally less crowded areas will become increasingly popular, while short weekend trips to major cities probably will become a less appealing proposition. Some travellers will also prefer private accommodation rather than large, centrally-located hotels. Long-distance travel to countries such as the US and the wider Americas region will also be avoided, at least until the epidemiological picture there improves.

Rasik walked 20 m towards north. Then he turned right and walks 30 m. Then he turns right and walks 35 m. Then he turns left and walks 15 m. Finally he turns left and walks 15 m. In which direction and how many metres is he from the starting position?
Two cars start from the opposite places of a main road, 150 km apart. First car runs for 25 km and takes a right turn and then runs 15 km. It then turns left and then runs for another 25 km and then takes the direction back to reach the main road. In the mean time, due to minor break down the other car has run only 35 km along the main road. What would be the distance between two cars at this point?
Starting from the point X, Jayant walked 15 m towards west. He turned left and walked 20 m. He then turned left and walked 15 m. After this he turned to his right and walked 12 m. How far and in which directions is now Jayant from X?

The COVID-19 pandemic is a stark reminder of our dysfunctional relationship with nature, environment and our food with studies linking the disease to the collapse of ecosystems and wildlife destruction. We need to rethink how we approach and value food, nature, the environment and our economy. It's vital that we ensure a Green Recovery to build back better after the Covid-19 crisis.
One thing is certain, nature friendly farming has huge role to play in securing a Green Recovery. Nature friendly farming can help tackle the climate and ecological crises, support vibrant rural communities and economies, produce plentiful healthy sustainable food and improve public health. In order to help achieve this we urge all political parties to commit to the following 6 key asks:
 1. Maintain and redirect payments towards mainstreaming nature friendly farming
 2. Commit to zero carbon agriculture by 2040
 3. Maintain strong environmental and animal welfare standards
 4. Build markets for nature friendly farming products
 5. Invest in local food systems
 6. Educate on food, farming and nature
Farmers should be better supported and rewarded for the good work we do for nature and the environment. A sufficiently funded future agricultural policy has huge play to play here, and can help reverse wildlife declines whilst creating a stable, long term income for farmers. And let's not forget that simple nature-based solutions such as tree and hedgerow planting, encouraging grassland biodiversity and peatland management can play a big role in tackling climate change.
Farming also needs to be profitable. We need a food system that ensures farmers earn a fair return whilst ensuring food is healthy, affordable and sustainably produced. Shorter and more transparent food supply chains can help achieve this. Many NFFN farmers are changing the way they supply the food they produce, and are marketing directly to the public, through local supply chains or online. Furthermore, food produced to high nature and environmental standards should be recognised in the market and that farmers adhering to them are rewarded.
Currently, there's a disconnect between customers and farmers and a lack of understanding on what is good or bad for the environment. We need to educate people where their food comes from and the positive environmental, social and economic impacts of nature friendly farming systems.
The wonderful thing about food is that you get three votes a day. Every one of them has the potential to change the world.

Not to be confused with pumice.
Pomace in a bladder press. These are Chardonnay grapes left over after pressing.
Pomace (/ˈpʌməs/ PUM-əs), or marc (/ˈmɑrk/; from French marc [maʀ]), is the solid remains of grapes, olives, or other fruit after pressing for juice or oil. It contains the skins, pulp, seeds, and stems of the fruit.
Grape pomace has traditionally been used to produce pomace brandy (such as orujo, grappa, zivania or törkölypálinka) and grape seed oil. Today, it is mostly used as fodder or fertilizer.
"Pomace" is derived from the Latin "pomum" (fruit and fruit tree).[1] The English were the first to use the term "pomace" to refer to the byproduct of cider production.[2]
In the Middle Ages, pomace wine with a low alcohol content of three or four percent was widely available. This wine was made by adding water to pomace and then fermenting it. Generally, medieval wines were not fermented to dryness; consequently the pomace would retain some residual sugar after fermenting.
Main article: Piquette
The Ancient Greeks and Romans used pomace to create a wine that later became known as piquette. This was an inferior wine normally given to slaves and common workers. After the wine grapes had been pressed twice, the pomace was soaked in water for a day and pressed for a third time. The resulting liquid was mixed with more water to produce a thin, weak wine.[3]
Apple pomace is often used to produce pectin and can be used to make ciderkin, a weak cider.
Grape pomace is used to produce pomace brandy and piquette. Most wine-producing cultures began making some type of pomace brandy after the principles of distillation were understood.
Pomace in winemaking differs, depending upon whether white wine or red wine is being produced.
In red wine production, pomace is produced after the free run juice (the juice created before pressing by the weight of gravity) is poured off, leaving behind dark blackish-red debris consisting of grape skins and stems. The color of red wine is derived from skin contact during the maceration period, which sometimes includes partial fermentation. The resulting pomace is more alcoholic and tannic than pomace produced from white wine production. Pomace from the Italian wine Amarone is macerated in Valpolicella wine to produce Ripasso.
In white wine production, grapes are quickly pressed after crushing to avoid skin contact with pomace as a byproduct of the pressing. The resulting debris is a pale, greenish-brown color and contains more residual sugars than it contains tannins and alcohol. This is the pomace normally used in brandy production.[2]
Other uses[edit]
Grape pomace from wineries in the Barossa Valley, South Australia. Top, white grape pomace; bottom, red grape pomace.
Pomace is produced in large quantities in wine production, with disposal an important environmental consideration. Some wineries use the material as fertilizer, while others are selling it to biogas companies for renewable energy. As envisioned, pomace would be introduced into anaerobic digesters that contain microorganisms that aid in its decomposition and produce methane gas that could be combusted to generate power.[4]
Specific polyphenols in red wine pomace may be beneficial for dental hygiene. A study conducted at the Eastman Dental Center found that these polyphenols interfere with Streptococcus mutans, the bacterium in the mouth that causes tooth decay. Professor Hyun Koo, the lead researcher of the study, hopes to isolate these polyphenols to produce new mouthwashes that will help protect against cavities.[5]
Grape pomace is also used in the oil and gas industry as a lost circulation material in oil-based drilling muds due to the pomace being fibrous and tannin-rich.
A 2004 study conducted by Erciyes University in Turkey found that pomace can also act as a natural food preservative that interferes with E. coli, Salmonella and Staphylococcus bacteria. Researchers pulverised the dried pomace from the white Turkish wine grape Emir Karasi and red Kalecik Karasi grapes; this was mixed with ethyl acetate, methanol or water and exposed to 14 different types of food bacteria. All 14 bacteria were inhibited to some degree by the pomace — depending on the grape variety and the concentration of the extract. The red wine Kalecik Karasi grape was the most effective; the researchers believed this was due to the higher concentration of polyphenols in red wine grape skins.[6]
Oenocyanin, a natural red dye and food-coloring agent, is produced from grape pomace. Tartrates (potassium bitartrate, 'cream of tartar') and grape polyphenols can also be manufactured from grape pomace.[2]

Super cool atom thermometer
(Nanowerk News) As physicists strive to cool atoms down to ever more frigid temperatures, they face the daunting task of developing new, reliable ways of measuring these extreme lows. Now a team of physicists has devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a degree above absolute zero. Their experiment is reported in the current issue of Physical Review Letters and highlighted with a Viewpoint in the December 7 issue of Physics.
Physicists have developed a new thermometry method suitable for measuring temperatures of ultracold atoms. (Illustration: Alan Stonebraker)
Physicists can currently cool atoms to a few billionths of a degree, but even this is too hot for certain applications. For example, Richard Feynman dreamed of using ultracold atoms to simulate the complex quantum mechanical behavior of electrons in certain materials. This would require the atoms to be lowered to temperatures at least a hundred times colder than what has ever been achieved. Unfortunately, thermometers that can measure temperatures of a few billionths of a degree rely on physics that doesn't apply at these extremely low temperatures.
Now a team at the MIT-Harvard Center for Ultra-Cold Atoms has developed a thermometer that can work in this unprecedentedly cold regime. The trick is to place the system in a magnetic field, and then measure the atoms' average magnetization. By determining a handful of easily-measured properties, the physicists extracted the temperature of the system from the magnetization. While they demonstrated the method on atoms cooled to one billionth of a degree, they also showed that it should work for atoms hundreds of times cooler, meaning the thermometer will be an invaluable tool for physicists pushing the cold frontier.

Many DIY projects go off the rails because the person doing the project dives right into doing without planning. No matter what kind of DIY project you take on, whether it is a craft or a total bathroom redo, there are six essential steps to ensuring it stays on track:
1. Take time to properly plan the project. There is a big difference between tearing a picture from a magazine and having a project blueprint. It's easy and fun to spend time poring over magazines, books, online articles and researching what you want your project to look like when it's done. But far too many people stop there.
Once you have a clear image of the goal, it is time to map out each of the specific work steps you need to take to complete the project. Be as specific as possible. Then divide each item on the list into one of three areas: foundational work, core work, finishing work.
Finally, map out a project schedule and budget. You should literally schedule appointments with yourself for working on each stage.
2. Don't go to the home-goods or home-improvement store in hopes of getting inspired. It's a surefire way to spend significantly more than you need to, and to waste time because you'll inevitably forget a critical item. Instead, make a thorough list of materials and tools you need to complete the project before you even leave the house. You can start a list using what comes to mind right away, but be sure to eventually use the project plan you created in the first step as a way to identify all of the tools and materials you need.
Then set your egg timer for 30 minutes and research where to find each of the items on your list. Check prices with online retailers and see if you can find coupons or discounts for what you need. Are you on or under budget? If not, determine what has to change.
3. When you go to buy the items, enlist some help. If you live with someone, consider dividing up the list by retailers and splitting up the errands. If you live with more than one person who can help, even better. It's a great way to speed things up and to ensure that everyone you live with has some pride of ownership in the finished project.
4. A DIY project can force one to learn new skills. That could be anything from learning how to grout tile to learning how to stitch a quilt piece together. Before you begin, identify what things you will need to learn and at what stage you will need to learn them. Then search for relevant "how-to" tutorials and have them at the ready.
5. There's always a surge of excitement once you begin. That's why it's particularly important to follow your project plan carefully during this phase. You don't want to cut corners in haste or forget something that's absolutely critical. But that's just the kind of thing that happens with alarming frequency if you're flying blind.
6. Final stages. This is where a lot of projects get bogged down and procrastination can set in. Avoid this by keeping those appointments you set in the planning stage and by identifying key milestones for this phase. If you get off track and are feeling overwhelmed, set an egg timer for 30 minutes each day after you come home from work and make consistent progress. Celebrate every milestone you complete. If you encounter a problem that throws you for a loop, head online to see if you can find answers. If you don't trust what you read, call in an expert for opinion and direction. Yes, it will likely cost you $150 to $200, but it's better to be safe than sorry.

income from peanut was not calculated in the present research because it is not the main crop. Although the biomass of weeds was not examined, weeds were clearly smothered by peanut plants in the intercropping plots. Different from other plants, peanut is a legume crop and it is able to fix nitrogen from the air. In addition to the weed smothering effect, peanut might interact in nitrogen nutrition with the main crop tomato, at least the peanut might not compete with tomato plants for nitrogen nutrition. Similar nitrogen release and supply by legume green manure crops were confirmed by Stute and Posner (1995) in cornfield. Peanut plants covered the soil surface between tomato row and suppressed weeds as found by McLenaghen et al. (1996). Dyck et al. (1995) have once conducted a field study using crimson clover (Trifolium incarnatum) as green manure in sweet corn field and confirmed the contributive effect of legume green manure in weed management. Boydston and Hang (1995) have obtained weed suppressive effect and potato yield increase by a non-legume plant, rapeseed (Brassica napus var. napus), as green manure. With their research results, many scientists suggest that allelopathic interaction between the green manure plants or the plant residues and the main crop may have been responsible for the weed suppressive effect of green manure (Dyck and Liebman, 1994; Gallandt et al., 1998; Liebman et al., 1995; Ohno and Doolan, 2001; Westoby et al., 1996; White et al., 1989). Combination of tomato and peanut, which covers the horizontal space together over the soil surface with different vertical canopy structure, minimized the invasion of weeds. As mentioned by Cardina et al. (1999) and Reader (1991), the cover crop can be selected to provide habitat for weed seed predators that are capable of reducing weed seed survival and elicit allelopathic chemicals that are capable to inhibit weed emergence and establishment. Smother crops, such as peanut used in the present
 - 70. 70 Hui-lian Xu experiment, have also been used in crop rotation between two main croppings to suppress the growth of weeds and break cycles of weed infestation associated with the production of the specific main crops (Robbins et al., 1942). A smother crop shades out weeds by its rapid growth and thick canopy. Often used smother crops are alfalfa (Madicago sativa), buckwheat (Fagopyrum esculentum), foxtail millet (Setaria italica), and rye (Secale cereale). Table 17. Fruit yield of tomato plants with peanut intercropped. 5.6.4 Weed control in paddy field by applying organic materials In the rice production, the beneficial organisms such as photosynthetic bacteria, earthworms even the unwanted weeds, pests and pathogens, all are related with the recycling of organic matter. It is expected that pests can be depressed by increasing the tolerance and competition of rice under an appropriate conditions favorable for the decomposition and utilization of organic matter in the soil. In nature farming rice production, it is expected that rice growth be promoted while weeds are depressed (Iwaishi and Umemura, 1998). Actually, undecomposed organic matter accumulates on the soil surface, decomposes during rice growth period and increases the organic mater in the root layer. This is why there should exist ideal paddy fields where weeds are not easy to propagate due to the cultivation practices. It is possible to control weeds by returning the rice crop residuals to the paddy fields and producing a condition for the residuals to be decomposed, as practiced by some farmers. In the research at INFRC Agricultural Experiment Station, the actual conditions of nature farming practitioners and the good experiences were analyzed and possibility of the practical use as a technique was confirmed. In 26 paddy fields from central to eastern parts of Japan there existed paddy soils whereby the growth of rice was promoted while the weeds were controlled by cultivation practices. The dominance of rice over the weed (M. vaginalis) or the weed over the rice and the damages by pest (L. oryzophilus) changed with alternations of the application
 - 71. Nature Farming in Japan 71 depth of rice straw with different decomposing extent and quantity. The adverse effects from the raw materials was overcome by mulching organic materials on the soil surface with positive effects of promoting activities of earthworms, improving soil structure and depressing weeds. Moreover, applications of organic materials confirmed the growth promotion from weeds control by earthworms and activities of photosynthetic bacteria. A long-term experiment conducted in the fields with M. vaginalis as the main weed and without any pesticide applications also confirmed that there exist paddy soils whereby rice growth is promoted and weeds are depressed. It is possible to adjust the soil nitrogen concentration and earthworm population by applying organic materials and changing puddling methods in addition to soil water management for weeds control. In addition, organic materials with high nitrogen content, such as oilseed mill sludge, fishmeal and rice bran, mix fermented with microbial inoculant, can applied to the soil surface in the paddy field to control weeds. The fermentation of the organic materials occurs in the soil surface layer and produces a soft muddy layer, where the weeds deposit into the deeper layers without germination and establishment. For a better fermentation and establishment of the soft muddy layer, the water should be shallow enough and the temperature should be high, so that the fermentation of the organic materials could perform well. 5.7 Integrated organic management of orchards Orchard management is difficult without pesticides and chemical fertilizers. This is especially true in Japan, where the appearance and color of fruit are very important, and the fruit will not be marketable if there is even a small blemish or scar on the surface or if the fruit is less than standard size (Fukuda, 1994). The consumer demand for these fruit quality parameters forces growers to use pesticides and fertilizers to ensure a large size and attractive appearance. Therefore, an integrated management is adopted in organic orchard production. The most common management of organic orchards in Japan is sod culture, fruit trees strip-intercropped with turfgrass. The original purposes to use sod culture are mainly the prevention of soil erosion and replenishment of organic matter. The roots deeply penetrating into the soil function as "the natural deep plowing machine" with soils undisturbed for small animals and microbes to thrive. In the opposite direction, killing grass with herbicide is called "clear culture", where the soil surface is ploughed and then exposed. Recently sod culture is managed with multiple purposes, such as enriching biodiversity especially the natural enemies, controlling the nitrogen metabolism to lower risks of diseases, minimizing soil erosion, increasing soil aeration and permeability, and supporting workers' equipment movement through the orchard during wet weather. The management practice involves use of a grass alley with a vegetation-free strip mulched by crop residuals in the tree row out to the drip line of the trees. This
 - 72. 72 Hui-lian Xu vegetation-free strip can be established and maintained by mulching rice and wheat straws or barks and wood pieces. The vegetation-free strip will help to minimize soil moisture and nutrient competition of grasses in the alley with trees, resulting in optimum tree growth. The vegetation-free strip may help minimize tree damage or loss from voles during the dormant season. 5.7.1 Principles and practices in orchard floor management Orchard floor under trees or sod culture has long been adopted in both conventional and organic fruit productions (Fujii, 1985; Ito, 1982; Matsui and Sasaki, 1979). Orchard floor is usually maintained with a planted cover crop of grasses such as Kentucky bluegrass, or legume such as clover (Kitaguchi and Yoshioka, 1988). Bluegrass is expected to form a thick sod. Clover is a low creeping legume and grows along the surface of the soil. Clover is an excellent nitrogen-fixing legume and releases nitrogen to the fruit trees. Estimates of nitrogen fixed by white clover in grass pastures are reported as high as 225 pounds per acre. Both Kentucky bluegrass and clover flower early in the spring and if left undisturbed should remain relatively dormant through the summer, minimizing competition with the fruit trees for moisture and nutrients. The common style of sod culture is a combination of a sod band between two tree rows with a weed-free zone within the tree rows. The weed-free zone is usually maintained with rice or wheat straw mulch. Sod culture offers several advantages over both complete tilling and chemical weed control. The permanent cover allows accesses to the orchard for cultural practices such as pruning, thinning, and spraying with machines easily passing through. The amount of dust in the orchard is also reduced, which is particularly important at harvest to prevent the fruit from being dirtied. Soil erosion caused by water run-off is reduced in sloping blocks. Sod culture is less costly than tilling or herbicides for weed control. Management of the sod orchard floor is difficult in practice because the orchard systems need to optimize all of the following objectives: 1) preserve soil structure, 2) maintain adequate soil organic matter levels, 3) enhance the biodiversity, 4) control weeds and other pests, 5) Allow efficient and effective irrigation of the tree crop, 6) allow efficient nutrition of the tree crop, and 7) allow access for orchard traffic.

Abstract: The aim of this study was to evaluate the role of stuffed mussel as a source of Listeria monocytogenes. Polymerase chain reaction is a rapid procedure with both sensitivity and specificity for quick detection and identification of L. monocytogenes. A total of 50 mussel samples were investigated for L. monocytogenes. L. monocytogenes was not identified by the conventional method. However, PCR amplification products demonstrated that 5 out of 50 samples showed positive reactions with L. monocytogenes. The PCR positive samples showed specific amplification at approximately 343 bp for L. monocytogenes.

Tape can be a very practical thing to have around! In animal health, tapes and wraps are often used to support, help with healing, bandaging, and to improve performance. But there are other, lesser-known applications as well.
In a paper published in 2006, authors were looking at ways to improve absorption of topical medications into the skin of horses. Different topical treatments can have different rates of absorption, skin irritation, and can lead to side effects if it doesn't absorb quickly.
These authors worked in a lab with frozen skin samples of Thoroughbred Geldings. They then worked with the skin samples the following ways:
- No skin treatment
- Cleaning the samples with chlorhexidine (mixed in solution or alcohol)
- Tape-stripped using adhesive tape
The authors found that all techniques of chemical cleaning increased skin absorption, but also that the skin previously treated with tape also had greater absorption, without needing to use any chemical preparation. This approach showed that horse skin reacts to topical treatments very differently when the skin has been prepared prior to treatments, which is important for caregivers to consider. Furthermore, the study shows that adhesive tape can be an effective skin preparation technique that doesn't require chemical treatments applied to the skin.
Is this an approach you use in your practice? If so, we'd love to hear from you! Contact us at _EMAIL_.

The creation of a beam using constructive interference between the signals transmitted by each antenna element is known as beamforming.
Beamforming can be done in two ways:
- Analog beamforming
- Digital beamforming
In analogue beamforming multiple antenna elements are connected to a single RF path and the RF source is split among all the connected antenna elements using a splitter.
Before radiating the signal into the propagation channel, we can steer the beam towards the desired direction by using phase shifters.
Using analogue beamforming, we can create only a single beam with high antenna gain towards a single user because we have only one RF path connected to multiple antenna elements.
For 5G FR2 analogue beamforming is the best option. Because the wavelength of mmwaves is very less. So they cannot travel long distances. By using analogue beamforming we can generate a signal with high antenna gain towards a single user. This is also known as the SU-MIMO technique and this depends upon the frequency/time domain.
In digital beamforming, each antenna element has its own RF path. All the signal processing will be done at the baseband including the amplification and the digital phase-shifting and individual signals will be passed through each RF path and will be radiated into the propagation channel.
With digital beamforming, we can create multiple beams in different directions. This is also known as an MU-MIMO technique where we can serve multiple users parallelly with different beams by allocating the same PRB's if they are spatially separated.
With this approach, we can serve a wide range of users and also can improve bandwidth efficiency. The disadvantage of digital beamforming is, it requires more RF paths which consume additional power.

Good Neighbors started in 1991 with the sole purpose of giving disadvantaged children a glimmer of hope. Back then, our organization concentrated on projects such as orphanages, handicapped children's programs, finding homes for widows stricken with poverty, rural community development, and assisting disadvantaged families of Tuberculosis patients.
We soon realized the dire need of similar aid in other parts of the world. In 1994, Good Neighbors became an international organization and was deeply involved in the Rwandan refugee situation, providing medical relief teams and establishing two non-formal schools at the refugee camps. Good Neighbors International became a formal entity in 1996, and since then we've expanded our projects and field offices to 29 countries around the world.
The United Nations
In August of 1996, Good Neighbors achieved General Consultative Status, the highest status level with the United Nations Economic and Social Council. Under the Charter of the United Nations, the Economic and Social Council may consult with non-governmental organizations (NGOs) concerned with matters within the Council's competence. The Council recognizes that these organizations should have the opportunity to express their views, and that they possess special experience or technical knowledge of value to the Council's work. In 2007, Good Neighbors was also recognized by the United Nations with the prestigious Millennium Development Goal (MDG) Award for our achievements in universal primary education.

The Mathematics of the National Highway Construction Cost Index
This document specifies the methodology which serves as the basis for the development of the National Highway Construction Cost Index, (NHCCI).
General Methodology for Calculating the NHCCI
The Fisher Ideal Index formula is applied using a chain-type indexing methodology to produce the NHCCI. The specific implementation and reasons for choosing this specification are given in this section.
Step 1. Definition of price index
The price index, It, of a specific cost item of highway construction (such as cement) gives the price of that item in period t, (pt), relative term to its price in reference period 0, (p0). The mathematical expression of It is:
Where, c represents the cost of the item and q represents the quantity of the item.
Step 2. Aggregating individual cost items into a total construction cost index
For highway construction as a whole, however, the direct price (p) does not exist because the price is the product of cost divided by quantity and the quantities of highway construction cost items are measured in different units which are not directly comparable and not additive. Therefore, we cannot calculate the price index of highway construction as a whole by directly implementing equation (1).
One natural way to derive the price index of highway construction as a whole is to calculate it as the weighted average of price indexes of individual cost items.
Where, superscript n represent the nth cost item and wn represents the weight assigned to the nth cost item.
Step 3. Choice of index formula
As equation (2) shows, the aggregate price index for highway construction as a whole not only depends on the price indexes of the individual cost items of highway construction, but also depends on the weights assigned to the individual price indexes. Therefore, how to weight the individual price indexes is essential in calculating an aggregate price index, such as the NHCCI. The choice of weights also leads to the choice of index formula.
In the economic index literature, there are three well known index formulas. They are the Laspeyres Index, the Paasche Index and the Fisher Ideal Index. In equation form, they are:
(3) (Laspeyres price index)
(4) (Paasche price index)
(5) (Fisher price index)
All three price index formulas use quantities of individual cost items as weights to their respective prices in calculating the aggregate price index. However, the Laspeyres price index formula uses quantities of the base period (0) as weights, while the Paasche price index formula uses quantities of the current period (t) as weights. The Fisher price index is a geometric mean of the Laspeyres price index and the Paasche price index.
Despite its many obvious advantages, the Laspeyres price index has its limitations. One of the limitations is that it usually overstates the impact of price increases and understates the impact of price decreases as the current period moves further away from the base period. This occurs because of the substitution effect when prices change in relative terms. Agents substitute away from goods whose relative prices increase so that the base year weights overstate the relative importance of these goods in the budget. As a result, the use of quantities from an earlier period as weights systematically biases the aggregate price index upward from the real change in aggregate price. In contrast, an aggregate price index derived from the Paasche price index formula is usually biased downward due to the substitution effect.
A second limitation of the Laspeyres index as it is often implemented is that as time goes on the fixed base year become less relevant to the current year or the year(s) of concern. However, if the base year is shifted forward in time, the entire index series will be changed. In other words, history will be rewritten every time the base year is changed.
The Fisher Ideal index, proposed by Irving Fisher in 1922, is one of the superlative indexes that give good approximations to the theoretical or "exact" cost-of-living index and yet are relatively simple to compute and use. Compared to fixed-weighted Laspeyres or Paasche Indexes, Fisher Ideal index takes the weights of both the base period and the current period into account. By doing so, Fisher Ideal index has the ability to accommodate the effects of substitutions, something the Laspeyres and Paasche indexes do not do. A major advantage of Fisher Ideal index over other superlative indexes, such as the Tornquvist index, is its "dual" property, i.e. a Fisher Ideal price index implies a Fisher Ideal quantity index, and vice versa. In other words, the product of a Fisher Ideal price index between two periods and a Fisher Ideal quantity index between the same two periods is equal to the total change in value (measured in current dollars) between those two periods.
All these advantages strongly suggest that the Fisher Ideal index formula is an excellent choice for building the NHCCI.
Step 4. Calculating aggregate price index for two adjacent periods
Since the OSI Bid-Tabs database provides data on bid value and bid quantity and estimated bid price data for each cost item of highway constructions in the United States, we can apply the Fisher Ideal Index formula to the bid quantity and estimated bid price data from Bid-Tabs data at the cost item (or Pay Item) level to calculate the NHCCI.
However, each time when the Fisher Ideal Index formula is applied to the price and quantity data, one and only one index number will be generated for the two time periods the data represent. In other words, the formula will not generate a price index series at once. The time period can be a month, a quarter, or a year and is usually determined by the data availability. An index number can be generated between any two periods in time. The two periods can be adjacent to each other. They also can be far away from each other with many periods between them. However, in order to build an index that accurately track price changes from one period to the next over time, it will be necessary to generate an index number for every pair of adjacent periods of the entire time period for which an index is build.
Step 5. Chain index numbers of adjacent periods into a time series of indexes
From the equations, we can see that the R1 is the index number of period (1) relative to period (0); R2 is the index number of period (2) relative to period (1); and Rt is the index number of period (t) relative to period (t-1); and that each index number presents the aggregate price of the current period in relative term to the aggregate price of the previous period. Mathematicians call this kind of indexing relative indexing. In relative indexing, an index number highlights the change in price from the adjacent previous period.
However, to show price changes over time, it will be more effective to compare the price of each period to the price of the base period. When an index is calculated by comparing the concerned period directly to the base period, it is called "direct indexing". The procedure of direct indexing is a dual process. That is, while the price of the concerned period is indexed in terms relative to the price of the base period, the price of the base period is also indexed to 1 and only 1. Therefore, the value of a direct index is always in terms relative to 1 and equal to the change between the two periods. This property provides the mathematical underpinning for the "chain" index procedure.
When the price of the base period (0) is indexed to 1, the chained index numbers, I1 for period (1), I2 for period (2), …, and It for period (t), can be calculated as:
In words, the chained index number of any period (to the base period) can be calculated as the product of the consecutive multiplication of the changes of the adjacent periods between the base period and that period. For example, with the chain-type procedure and annual rates of changes (Rt), the index of year 1995 to year 1990 (I90,95) can be calculated as:
In summary, the Chained Fisher Ideal Index method for building the NHCCI contains two steps. In the first step, Fisher Ideal Index formula is used to calculate changes in aggregate price between adjacent periods with bid quantity and estimated bid price data at the cost item (or Pay Item) level from Oman Bid-Tabs database as inputs. This step is also an aggregation process. Changes in aggregate price of highway construction as a whole calculated in this way are essentially the averages of quantity weighted changes in the prices of the cost items of highway construction. In the second step, changes in aggregate price between adjacent periods are chained together through consecutive multiplication to form a time series of aggregate price index for highway construction as a whole.
The Chained Fisher Ideal Index method recognizes the need for estimating changes in the aggregate price of highway construction as a whole to use weights that are relevant and appropriate for the specific periods being measured. The Chained Fisher Ideal Index method has three important advantages over Fixed-Weighted Indexes. First, while it makes aggregation of price changes in many and different cost items into one measure through weighting, it captures the effects of changes in the relative importance of different cost items in highway construction over time. Second, it minimizes substitution bias and, at the same time, provides a more accurate track of price changes in highway construction cost items as a whole. Third, it eliminates the inconvenience and confusion associated with Fixed-Weighted Indexes of updating the weights and base periods, and thus rewriting economic history, as base periods move further and further into the past and become more and more irrelevant

Philly Youth Radio won a $600 grant at Stake #6
Philly Youth Radio
1. Describe the project a STAKE Grant would help you accomplish (100 words):
Philly Youth Radio (PYR) is a project that works with a diverse group of local high school students to produce radio stories about their lives and communities. Through a series of intensive radio workshops, students work closely with professional radio producers to create broadcast-quality stories that have been aired on major media outlets. Our hope is that these stories will promote intergenerational, intercultural dialogue, as well as better understanding about young people's experiences and contributions in this city. PYR runs project-to-project and a STAKE grant would move us one step forward in beginning our third season.
2. How will you use the grant toward the realization of your project? $750 is your imaginary budget (50 words):
For PYR's third season, we plan to teach a series of intensive radio production workshops in which we pair youth radio apprentices with adult students to create collaborative audio/visual stories about love and relationships.
Youth radio apprentice stipends: $400
Teaching materials: $150
Outreach materials/listening showcase: $100
3. A little about yourself and what led you to your current creative goals. This may include a previous project of yours, ways it both succeeded and failed (this can be entirely unrelated to your proposal) (100 words):
Yowei Shaw is a freelance reporter and audio producer. Beth Patel is an independent audio producer and youth advocate. PYR's first installment, "Students of Violence," has been featured on alt.NPR's YouthCast, Generation PRX, WHYY, and other media outlets. The overwhelming response to our first project prompted a second "season" of PYR in 2012, titled "Teen Sanctuaries." Our main challenges include a shortage of time and funding. We feel that we could create better stories with our students if we had more time to work on them together. However, without adequate funding, we make do with the time that we have.
4. Why is this project important? How will it benefit the community? (100 words):
This project helps project the voices of young people in our communities. We ask students to discuss issues that matter to them and then help share their stories on a larger stage. Throughout the process, students improve their writing, editing, and voicing – skills that will be useful long after the project has ended. Most importantly, our students learn to collaborate with adults in a reporter/editor relationship formed through mutual respect and dedication to the best story possible. We feel that our students are leaders in their respective communities and that PYR is important to shaping that leadership.

Explain in basic terms how to execute managed code. | Eklavya Online
Explain in basic terms how to execute managed code.
Executing code is an essential function of any developer, but knowledge of executing managed code is specific to the.NET Framework. Your answer should explain how to execute code that runs inside the common language runtime environment the framework provides.
Additionally, whenever an interviewer asks you to explain something in "basic terms," it's important to pay attention to the language you use to make it as clear as possible. These types of questions are often asked when the position requires the candidate to be both very technical and also a good communicator who can explain their work to a broad audience. In some organizations, a lead developer may be responsible for reporting progress on an application to stakeholders. During these exchanges, they should be able to break down their work without using technical jargon or overly complicated language.
Example: "First, I would write the code. Then I would compile the code with a resource called a compiler. Using the compiler, I would convert the managed code into an intermediate language. The intermediate language will be targeted by the Common Language Runtime within.NET Framework and converted to native code that can then be executed inside the framework.
In my previous role as a developer, I was tasked with speeding up application delivery times. Using.NET and this process for executing managed code, I was able to reduce delivery timelines by 5% overall."


It doesn't take a rocket scientist to realise that if you cannot count on a flood of new postpaid customers to fuel your growth, you need to create more value from your existing prepaid subscriber base. With this in mind, I have put together 15 practices to help you increase the value of your prepaid subscriber base while maintaining positive user experience of customers. Some of these tips are applicable just as well to your postpaid activities.
 1. Map all customer interactions
Map all the touch points with customers via all channels to prevent conflicting messages and offers. You want to prevent a scenario in which customers reach an IVR and get an automatic offer that contradicts the personalised offers you have worked hard to design.
 1. Make it simple
Design simple offers with clear conditions, and preferably with immediate rewards. For example, "Recharge 10€ or more by the end of the week and get 4€ to be spent on data."
 1. Be 'contextual'
Take into an account subscribers' profile and attributes (static data such as price plan, behavioural patterns such as personal number of days between Top-ups or Max Top-up in the last 3 months, preferred communication channel, responsiveness to past activities) and design the overall marketing proposition (targeting, offer description, communication channel, communication text, user experience etc.) to fit these personal attributes.
 1. Simulate natural response rates
Try to run the rules of the offers on your subscriber base to predict response rates of the target segment you defined. Based on your simulation results, adjust the targeting or offer conditions to maximise the offer efficiency (target group versus control group response rates) and relevancy.
 1. Implement churn predictors
Apply real-time and near real-time modelled churn detectors to prevent churn attempts. Modelled churn predictors will identify abnormalities in customer's behaviour and allow you to react immediately.
 1. Allocate a benefits budget
Allocate a benefit budget that takes into account the customer's ARPU and overall value to avoid cannibalisation.
 1. Simplify response for churners
Make it as easy as possible for subscribers who are in-risk to churn to respond to offers and remain connected. For example, avoid cumbersome registrations procedures.
 1. Choose the right words
Always probe copy alternatives. Consider focusing the marketing text so it addresses customers' personal pain. For instance, for customers who are sensitive to cost, create copy that emphasises the monetary value of the incentives provided.
 1. Ensure wide coverage
Make sure your contextual marketing plan covers a large portion of the subscriber base, or if not, apply a complementary plan to address it. Wide coverage is highly important for achieving the overall desired Top-up lift, so you should consider combining reactive/contextual and proactive communications.
 1. Send time-based offer reminders
Communicate personal reminders (e.g., "You have 3 more days to Top-up 10$ or more and get 5$ back! Top-up today!"). These reminders generate better response rates than invitations, due to their time limit and urgency which triggers a reaction. The recurring effect of the message also increases its effectiveness.
 1. Use benefit reminders cautiously
Be careful when raising awareness to unused benefits or incentives. Such reminders can be risky in terms of user satisfaction and may drive churn.
 1. Send benefit confirmations
Consider issuing a benefit confirmation communication in order to reduce calls to Customer Care and to increase customer delight
 1. Tailor Recharge and Spend flows
Stimulate customers with a personal low balance to recharge their account; motivate customers with a high balance to spend it by proposing new services, activating bundles (one-off or recurring) and so on.
 1. Analyse competitors' offers
While this may seem obvious – still, you must be acquainted with market competitors and their marketing propositions, and visit their web sites and stores occasionally. You can get ideas and implement unique personalised offerings within your Below-The-Line marketing initiatives.
 1. Mix and match
Combine contextual behavioural triggers with special occasions (such as Pay day or a Sports event). For example, during the Olympics you can offer a discounted data bundle for viewing sports news and watching Olympics videos. The contextual offer can target low data users with no data bundle whose current balance supports the data bundle price.

The following guidelines should be followed when entering a flooded area with any type of gas and/or electric present:
 1. Have the utility companies shut off the gas and/or electricity.
 2. Do not touch the fuse box or any plugged-in cords or appliances until the electricity is shut off. Touching these could result in electrocution.
 3. If an electrical appliance motor or any controls are submerged under water do not start it until consulting with the dealer or a service company.
 4. Do not re-light appliances until checked by the gas company. Make sure all pilot lights are on before re-lighting burners.
 5. Do not light matches until the gas is turned off. If there is a gas leak it could cause an explosion.


for this type of insert optimization.
Problem analysis
The results of the previous tests raised questions: "How do we explain the performance degradation in the case of columns number growth?" and "How do we minimize this effect?"
I selected three factors that I believe affected response time and tried to investigate their influence on the result.
Suggested Influence
Round trips
A statement invocation on server takes time. The more rows are wrapped into a single INSERT the less statement invocation we have. Using multiple rows insert minimizes round trips.
Number of parameters in a statement
Parameter binding, sending and parsing takes time. The more parameters we use the more time is spent on binding and parsing on server side.
Insert operation time
Clear time of insert without time spent in sending, binding and parsing parameters. The more rows are wrapped into a single INSERT the less time is spent. Using of multiple rows insert should minimize INSERT operation time.
Table 3
My idea was to understand how much time we spent sending, binding and parsing data and how long the INSERT operation took.
I used a trick to gauge how long the INSERT operation took. I created a copy of the program that sent the same data to the server but did not execute the INSERT statements. I wanted to compare the results shown by program that sent data and executed INSERT statements with the results of the program that just sent data.
For comparison, I took the results of the first test with a two column table. The results of both programs are presented in Image 7. To calculate the INSERT operation time, I subtracted the results of the program without INSERT from the program executing INSERT.
Image 7
Through multiple rows optimization, the INSERT operation time was reduced from 21 seconds to three seconds, and there was no degradation. When a single INSERT contained more than 100 rows, the results of a program with INSERT and without INSERT became very similar. Both programs spent a lot of time in sending, binding and parsing data.
The best result for multiple rows insert was 9 seconds (25 rows per insert), and only 4 seconds were spent inserting data. During the test with the single row insert, the total time was 56 seconds, 21 of which were spent executing INSERT and 24 seconds on sending and binding.
When increasing the number of rows in a single statement from one to 1000, the sum of round trips and parameter binding time decreased, but with 100 rows in a single INSERT it began to increase. To insert 100 rows in one statement I used 200 parameters. It's likely that the positive effect of decreasing the round trip time was negated by the parameter binding and parsing. In my testing environment, the number of parameters in a statement should be between 100 and 200. When the number of parameters was above 200, serious response time degradation was observed. The program without INSERT shows that this effect relates not only to multiple rows insert, but to any statement with parameters including stored procedures.
In my test programs the number of parameters was the main limitation. The most significant amount of time was spent on parameter processing.
Problem minimization
To minimize the influence of the number of parameters, I decided to try and use parameters more efficiently.
I took the case which had shown the worst result: the table with 23 columns (t23). I put all the 23 values into one string variable where every field had a fixed length. Instead of sending 23 parameters for each row I sent one in the form of string. I repeated a set of tests wrapping one, two, five, 10, 25, 50, 100 rows in a single INSERT statement. To get certain column value during execution of INSERT I used substring operator, I called this method "sub stringed multiple insert".
The INSERT statement for three rows in a single statement looked like this:
Table structure:
U1 uniqueidentifier, U2 uniqueidentifier,I1 int, I2 int, d1 datetime, I3 int, I4 int, 15 columns varchar(40);
Step A. Put 23 values in to a string variable for every row using concatenation ("+")
Declare _USER_ varchar(..)= [column 1] value + … [column 23] value;
Declare _USER_ varchar(..)= [column 1] value + … [column 23] value;
Declare _USER_ varchar(..) = [column 1] value + … [column 23] value;
Step B. Insert data using substring.
Insert into t23(c1,c2,..c23) values
(substring(_USER_,1,32), substring(_USER_,33,32), …. substring(_USER_,xx,40) ), –1st row
(substring(_USER_,33,32), substring(_USER_,33,32), …. substring(_USER_,xx,40) ),– 2nd row
(substring(_USER_,33,32), substring(_USER_,33,32), …. substring(_USER_,xx,40) ),– 2nd row
Using "sub stringed multiple insert" I managed to reduce the multiple rows insert results from 79 seconds to 37 seconds for the table with 23 columns.
The results produced by the single row insert, multiple rows insert and "sub stringed multiple insert" for tables with a different number of columns are presented on Image 8.
Image 8
"Sub stringed multiple insert" supported my hypothesis about the main limitation. After minimizing the number of parameters, the result was improved in spite of spending additional CPU resources to perform substring operation.
Comparison of multiple insert method with bcp, TVP procedure and single row insert
Finally, I decided to compare multiple rows insert with other data load methods. I used bcp utility, the procedure with INSERT from TVP, the single row insert and "sub stringed multiple insert". I completed two sets of tests. In the first set, I loaded one million rows, in the second one, 10 million. I took the tables with different numbers of columns which I had used in the previous tests. In these tests, I wanted to define the influence of the number of columns on insert speed for all the methods. The results of the tests are shown in Image 9 and Image 10.
Tables had the same structure as before.
In the tests, I filled character columns completely according to its full size.
Image 9
Image 10
All the methods suffered from increasing the number of columns.
The length (in bytes) of each row for the table with ten columns was equal to the twenty-three column table. Performance for the twenty-three column table was significantly longer.
Bulk copy utility (bcp) was the fastest data load method and "Sub stringed multiple rows insert" was a close second. Multiple rows insert was faster than the single row insert and faster than TVP in two of the four cases.
In order to minimize execution time when you are loading data, it is better to insert several rows at once using INSERT... VALUES. Even by inserting two rows in a single statement you can reduce the execution time over single row insert.
For the single row and multiple row insert, good performance is possible only if you use explicit transactions. Wrap _PHONE_ statements into a transaction. Don't use auto-commit!
Even though you can have 1000 rows in a single INSERT... VALUES statement, doesn't mean you should. I got the best results with a relatively small number of rows in a single INSERT: two, five, seven and 25 rows worked best.
The more columns you have in a table, the lower the effectiveness of INSERT optimization. With 23 columns, the advantage almost vanished. This was due to the fact that the time spent parameter binding and parsing dwarfed any saving in inserting several rows in one statement. Be careful using parameterized statements with a large number of parameters (more > 100), not just with multiple rows insert, but with all the statement types including stored procedures. Such is the slowness of parameter binding that it was quicker to put all the values for one row into one delimited string and sending it in one parameter instead of several. This, combined with multiple rows and using the substring function to get values back, could improve data load speed.
Now that I've completed 45 different experiments, here's what I've learned: The fastest method to load data into SQL Server is bcp, with "sub stringed multiple rows insert" as a close second; multiple row insert consistently outperformed single row insert; and the number of columns involved in the insertion of a table was a serious limitation for all the methods.

And now, in English! Take a look at the mind map! As you can see, the symbol of Superman is used deliberately. The first idea that came to my mind when I was developing the map was to draw a really eye-catching symbol in the central position so that it can easily be associated with the tense given. Why Superman? The initial S is a really distinctive feature of the Present Simple Tense, since it is added to the verb used with the third person singular. In particular, English-learners will often forget to add –s when they use the Present Simple. The central drawing is here to remind the visual types of learners not to forget the most specific fact concerning the grammatical form. As you can see, the purple branch gives a clear illustration of the positive form of the verb given. The ant here represents plural since ants are numberless insects.

Gaonim (gāōˈnĭm) [key] [Heb., = excellencies], title given to the heads of the Jewish academies at Sura and Pumbedita in Babylonia immediately following the period of the Saboraim until the middle of the 11th cent. Thereafter the title was adopted by the heads of the Palestinian academies; later it was used as an honorific title to indicate a great scholar. The Gaonim asserted the primacy of the Babylonian Talmud over the Palestinian Talmud and contributed to the standardization of Jewish law and liturgy. The greatest Gaon at Sura was Saadia ben Joseph al-Fayumi. Of those who held office at Pumbedita, Sherira Gaon (968–98) and his son Hai Gaon (998–1038) are most notable. Under Sherira the waning prestige of the Babylonian academies was restored, and it was maintained by Hai until his death. Thereafter European Jewry came to play an ever more dominant role in Jewish life.

TOF sensor fusion
Most range sensors basically use the TOF (Time of Flight) of an echo signal to offer their distance to the closest obstacle in the direction of the sensor, but many of these can be rotated like a sonar in a submarine to cover a wider range of detection. Others, like cameras, provide information on a wider area, but this information is typically more complex to process. In a dynamic, potentially unstructured environment, a quick response time might be the difference between safety and collision, so in many cases, when video cameras are used, they are combined with other range sensors to achieve faster responses. Furthermore, visual information is so rich that video processing has only been solved when some constraints can be applied. These restrictions usually imply some knowledge about the operation environment and a heavy specific problem-solving orientation. Simpler range sensors also present their own drawbacks. Sonar sensors, for example, have an uncertainty angle that, in models like Polaroid, may be up to 22.5º. Consequently, when obstacles are at a significant distance, say 4-5 m, we know how far they are, but not exactly where. Infrarred sensors are sensitive to natural light and their output may change sharply when there is a significant illumination change, like whenever someone is stepping in front of a window. switches on a light or opens a door. Lasers can not detect glass doors and deal poorly with black surfaces. Furthermore, all three of these sensors only detect obstacles in their own plane, so irregular objects like a table might be completely missed. Recently, though, laser sensors have become smaller, cheaper and stronger, so they have been particularly favored by the wheelchair industry. A classic SICK LMS 291-S05 laser weights 4.5kg and is 156 x 155 x 210mm, whereas a modern Hokuyo URG-04LX weights 160g and is just 50 x 50 x 70mm.
In any case, since all sensors have advantages and drawbacks, it is usual to work with several ones or, at least, to statistically combine the readings of a single one in time and space to obtain more reliable knowledge on the environment. If these readings are combined in a short time span within the surroundings of the robot, range sensor readings can be used to avoid close obstacles by heading it in a free direction. Readings can also be combined into a wider model of the environment to predict more efficient and safer trajectories to the goal, to combine several goals or to coordinate different mobiles. In order to build global models of the environment, though, it is important to know the position of the mobile within the environment with some accuracy. Otherwise, it would be like asking directions to someone who is actually lost.

| In 1938, the Board of Directors of the Texas A&M College authorized the development of an airport at the existing site. The University applied to the Civil Aeronautics Authority (CAA) for certification as a primary flight training school under provisions of the Civilian Pilot Training Program. In 1940, the airport was formally named for Navy Lt. Jesse L. Easterwood. Easterwood was a former student of the College who enlisted in the Naval Air Service in 1917. After being commissioned as Ensign, he was later promoted to Lieutenant in the Naval Air Service and was the second American to qualify as Naval Aviation Pilot. He served with the Royal Flying Corps in 1918 and had to his credit sixteen successful raids behind German lines. He served in three foreign countries and was killed in an airplane accident in the Canal Zone May 19, 1919. He was awarded the Navy Cross posthumously "for distinguished and heroic service as an aviator."
The original facility in 1940 consisted of one hangar and a turf landing strip and taxiway which were eventually paved through funding provided by the CAA, the Works Projects Administration (WPA), and Texas A&M. In 1948 a large hangar was relocated to the airfield from a US Army flying field near Corsicana, Texas. The FAA established a Flight Service Station (FSS) at the Airport in 1951 and Pioneer Airlines began scheduled air service in that same year. Many changes have occurred over the years including moving the Flight Service Station to Montgomery County and Continental Connection and American Eagle now provide scheduled air service.
The first control tower was erected at the Airport in 1952 and a commercial passenger terminal was constructed in 1957. Work began on an extension of Runway 16-34 to its present 7,001 foot length in 1984. At the same time the associated parallel taxiway to Runway 16-34 was also extended. In 1988, work began on improvements to the Airport access road and initial construction of a new passenger terminal began. The new McKenzie Terminal became operational in 1990. Upon completion of the McKenzie Terminal, plans were made to convert the old passenger terminal into a general aviation terminal to meet the needs of these passengers and pilots, including corporate operators that use the Airport. The old passenger facility was remodeled to meet the needs of this segment of the aviation community and re-opened for service in 1994 as a modern general aviation facility, housing line service and support personnel as well as flight operations.
The number of dignitaries and quality events supported by Easterwood far exceeds those of many airports much larger than Easterwood. The airport regularly supports dignitaries arriving for special events at the University or the George Bush Presidential Library and Museum. The airport is only two minutes from the campus or library by motorcade. This proximity to the University makes it especially desirable for visitors. Some of the special activities and guests passing through Easterwood Airport have included:
- Bush Library Opening
Easterwood Airport parked almost 200 private and corporate aircraft on the day of the library opening, the largest number ever at the airport. Special guests attending the library opening that passed through the airport included then President Bill Clinton and First Lady Hillary Clinton, Former President Gerald Ford, Former First Ladies Nancy Reagan and Lady Bird Johnson, Former President and Mrs. Jimmy Carter, Governor and Mrs. George W. Bush, Dr. Billy Graham, and Mr. Newt Gingrich.
- Athletic Events
Big 12 collegiate athletic teams regularly fly into and out of Easterwood Airport, in charter aircraft ranging in size from a King Air to a Boeing 757.
- Former President Bush's Parachute Jump
The airport served as the base for the former president's parachute jump to celebrate his 75th birthday and his 80th birthday.
- Medical Flights
The airport routinely supplies fuel, flight planning, weather and various other needs for Life Flights, Angel Flights, and Military Medi-vac flights.
- Special Guests
Special guests that have been greeted at Easterwood Airport by the Ross Volunteers include:
- Governor George W. Bush
- First Lady Laura Bush
- Former President and Mrs. George Bush
- Prime Minister Tony Blair
- Former Prime Minister John Majors
- Jorge F. Quiroga Ramirez, President of the Republic of Bolivia
- National Security Advisor Condoleeza Rice
- King Mohammed VI of Morocco
- General Norman Schwarztkopf
- Former Soviet President Mikhail Gorbachev
- Governor Rick Perry
- Chairman of the Joint Chiefs of Staff Colin Powell
- Reverend Franklin Graham
- Bill Cosby and Jeff Foxworthy, entertainers for First Yell

How do you draw the structure of the reaction of 1-hexene with h2o in the presence of acid
If you mean the acid is a catalyst, then the major product will be 2-hexanol, because Markownikoff's Rule predicts the -OH group will go to the carbon atom with
fewer H atoms (#2 carbon in this case) and the H group goes to the C atom
with more hydrogens (#1 in this case).
