Hluk v životním prostředí z pohledu fyzické geografie
Křečková, Michala ; Matějček, Tomáš (vedoucí práce) ; Přibyl, Václav (oponent)
This study investigates the sound propagation in the environment, defines sounds and related noise and describes their sources and features in general. The importance of noise as the environmental factor has shifted up sharply in the last decade and the sound propagation depends on many different circumstances. These factors, such as meteorological conditions, topography, ground cover or presence of vegetation cause changes in the sound propagation. Furthermore, nature itself can be also the place, where the sounds are generated. In the study were also listed impacts of sounds in landscape according to the origin (geophone, biophone and antrophone). In the practical part of this study the noise reduction effect of vegetation was investigated. More than 70 vegetations profiles with 43 vegetation species were covered and investigated. Six different kinds of vegetation were taken into account (conifers, broad-leaved trees, mixed forest, field thickets, herbs and belts of shrubs). To make comparison with the figures the last investigation was made in the open ground as the basic measure to compare the difference in sound pressure levels between the tree belts, theoretical attenuation and open ground. Point source of noise was set up in various distances in the front of the tree belts. Level of noise at various...

'Children's Chorus'
A prompt from We Write Poems: Congregate.
'Children's Chorus'
They are a part of something really grand -
They know this much as they fill up the stage,
The little ones are just six years of age,
It might be hard for them to understand,
Or maybe not. In simple black and white
They stand like one. Aware of their cause,
They hold their breath, before takeoff they pause,
All eyes on her… And then her hands take flight -
And music starts.
Live for the Love of it,
The Happy Amateur
 1. I understand that feeling very well. Choirs are great for togetherness.
 2. My daughter joined a choir not long ago, and it's been a wonderful experience. I'm so happy for her. Thank you for the comment, Viv.
 3. Singing in a choir is a special feeling, and you have described it well, Happy.
 4. Thank you, Pamela, I haven't sung in a choir :-( but my daughter, a chorister, approved of my poem :-)
 5. Choirs are very nurturing experiences for kids usually and you've captured that with your poem... nicely done

A key by which a Node's additional information can be accessed.
 - Key
 - Basic
 - Identifiable
 - Object
 - Anything
Initializer
Key(String name)
Parameters:
 - name
 The name of this key. To avoid collisions with other keys, some use-site ID should be included, e. g. the name of the module that uses this key.
Attributes
hashshared actual Integer hash
The hash value of the value, which allows the value to be an element of a hash-based set or key of a hash-based map. Implementations must respect the constraint that:
 - if x==y then x.hash==y.hash.
Therefore, a class which refines equals must also refine hash.
Because the Integer type is platform-dependent a compiler for a given platform is permitted to further manipulate the calculated hash for an object, and the resulting hash may differ between platforms.
Refines Identifiable.hash ultimately refines Object.hash
idshared String id= "'' 'Type'.string '':::''name''"
A unique ID of this key, composed of the name argument and the Type type argument.
stringshared actual String string
A developer-friendly string representing the instance. Concatenates the name of the concrete class of the instance with the hash of the instance. Subclasses are encouraged to refine this implementation to produce a more meaningful representation.
Refines Object.string
Inherited Attributes
Attributes inherited from: Object
hash, string
Methods
equalsshared actual Boolean equals(Object that)
Determine if two values are equal. Implementations should respect the constraints that:
 - if x===y then x==y (reflexivity),
 - if x==y then y==x (symmetry),
 - if x==y and y==z then x==z (transitivity).
Furthermore it is recommended that implementations ensure that if x==y then x and y have the same concrete class.
A class which explicitly refines equals() is said to support value equality, and the equality operator == is considered much more meaningful for such classes than for a class which simply inherits the default implementation of identity equality from Identifiable.
Refines Identifiable.equals ultimately refines Object.equals
Inherited Methods

Free Today: Mothers: Their Power and Influence
Today's Free Kindle eBook: Mothers: Their Power and Influence
A unique bondDr Ann Dally, a practising psychiatrist, provides an in-depth perspective on mothers, based on her experience observing mothers at a personal level. Her perspective is intended to provide mothers, and new mothers, with a deeper understanding of the forces that may at times seem irrational. She explores the three stages of motherhood: enclosure, extension and separation and stresses that it is important to understand these stages to be able to identify certain behavioural patterns. Although there are a variety of other factors, understanding the mother-child relationship does play a significant role.Included throughout the book are true accounts of Dr Ann Dally's encounters with mothers and children, as well as excerpts from well-known works from D.H. Lawrence and Philip Roth, who both wrote about their own 'enclosing' mothers. Going beyond the three stages of mothering, Dr Ann Dally covers the three types of environment that tie in with the stages of mothering. This important analysis provides a further understanding of how the mother's behaviour, along with the environment that surrounds the child, impacts a child's future. Mothers: Their Power and Influence sheds light on a variety of perspectives and really explores the dynamics and behaviours that make up mother/child relationships. Praise for Ann Dally'Thorough and engaging' – Kirkus Reviews 'introduces a levelheaded view' – Kirkus Reviews 'refreshingly evenhanded' – Kirkus Reviews Dr Ann Dally (_PHONE_) was a pioneering English author and psychiatrist. She was born in London, the daughter of a distinguished lawyer and a half-American mother. She studied history, before qualifying in medicine and then in psychiatry, whilst going on to marry and have six children. Ann Dally wrote eleven books in all, including A-Z of Babies, The Intelligent Person's Guide to Modern Medicine, A Child is Born, and The Morbid Streak.

In this case study I will be looking at one state, that is Punjab, and compare the differences of the population density between two districts, one rural and one urban, within that state, I will do this by looking at the birth rate, death rate fertility rate and infant mortality rate etc. And examining the fact and analysing them which led to the differences. In Jalandhar, the rural district, we see that the population is 1,962,700. In Amritsar, the urban district, the population is 3,096,077. The population is much larger in Amritsar, and we can say that Amritsar is a more urbanised area in Punjab.
This is because the government have spent much money to develop the area as it's a major city of tourism due to the location of the golden temple. This has also attracted both tourist and many people from rural areas. So the increase in population adds to the increase of population density in that area. In Jalandhar we see that as it's a rural district the population stays low therefore this plays one major role in leading to the low population density. Another point that I feel is correlated is that the people per household is proportionate to the number of population.
This is because as the area of the district is limited when there is an increase in the population the average space per person will decrease, this will lead to a rise in the people per household and therefore cause a higher population density. Now looking at Amritsar we can see that the number of people per households is 6, this is a high number is responsible by the high number of population, this number would have been higher if the area was low, but as it was high the number of people per household turned out quite less.
In Jalandhar we see that the number of people per household is 5, there not much different between Jalandhar and Amritsar this is because the area of Jalandhar is much smaller to that of Amritsar and this lead to an increase in the number of people per household. Therefore this proves our theory that as the population increases so does the people per household. So these factor effect the population density in a propionate way. I. E. if the population and number of people per household increases so does the population density.
Looking at the Birth rate and death rate, as the records were not found for each district I decided to use the different age group population and use the term 'high birth rate, low birth rate, high death rate, low death rate' according to how many people were in each age group. Now in Amritsar we see that the birth rate is quite high, this is because within the age group 0 – 4 we see that the population is 286,056. This tells us that the birth rate will be high and also the infant mortality rate will be quite low since the population of children is high.
Now looking at the rest of the age groups we see that the population is still quite high and this leads us to assuming that the death rate must be quite low as the population of the age groups does not decrease by a great amount. Also as we can see the number of people which live beyond 60 years is 283,409 this number is quite high and therefore we can say that the life expectancy is also high. To conclude this we can say as Amritsar is an urban city the medical facility is high and this is proved by the high number of population.
Drawn below is a sketch of the population pyramid of Amritsar from the assumed data written above. Now looking at Jalandhar we see that the population of people in the age group 0-4 is 154,749 this figure is much lower than what we saw in Amritsar. So therefore we can say that the birth rate is either low, this is unlikely as it is a rural district, or that the birth rate is high but the infant mortality rate is very high. In the other age groups we see that the population does not increase at an exponential rate and it is much lower than the figures in Amritsar, so this tells us that the death rate is high.
And also as there are relatively few people above the 60 year age group therefore meaning that the life expectancy is low. To conclude this we can say, as Jalandhar is a rural city the medical facility is low and this is proved by the low number of population as compared to Amritsar. These factors here also affect the population density again in a proportionate way. Drawn below is a sketch of the population pyramid of Jalandhar from the assumed data written above.
Now looking at both the population density of Amritsar and Jalandhar. We see that Amritsar has a population density of 619. 21. This is quite high but it's expected from an Urban district in a LEDC. Reason have been explained above, human and physical factors is listed below. In Jalandhar the population density is 577. 09 we can see this is lower than Amritsar's but still quite high, it is high because it is in a rural district region but it is lower than Amritsar's because jalandhar has a higher death rate.

Controversial issues: guidance for schools
7. The importance of citizenship education
A consideration of the issues surrounding the teaching of controversial issues serves only to underline the importance of good citizenship education from an early age.
If children become accustomed to discussing their differences in a rational way in the primary years, they are more likely to accept it as normal in their adolescence.
Citizenship education helps to equip young people to deal with situations of conflict and controversy knowledgeably and tolerantly. It helps to equip them to understand the consequences of their actions, and those of the adults around them.
Pupils learn how to recognize bias, evaluate argument, weigh evidence, look for alternative interpretations, viewpoints and sources of evidence; above all to give good reasons for the things they say and do, and to expect good reasons to be given by others.

In conclusion, Ontario is a unique place that showcases its cultural diversity through its festivals and events. Toronto's Toronto Caribbean Carnival and Stratford's Shakespearean Festival are just a few examples of the excellent cultural events that happen in Ontario. These festivals are essential in promoting cultural exchange and celebrating the region's past and present.
How has city planning and development impacted the overall niceness of Ontario's cities?
City planning and development has played a significant role in shaping the overall niceness of Ontario's cities. Over the years, city planners have been striving to create livable and attractive communities that meet the needs of their residents. They have focused on creating safe and walkable neighborhoods, providing access to public transportation and green spaces, and enhancing the overall visual appeal of the city.
One of the most significant impacts of city planning and development on Ontario's cities has been the creation of vibrant and diverse neighborhoods. City planners have encouraged the development of mixed-use spaces that combine residential and commercial buildings, which has created lively communities where people can live, work, and play. Moreover, the development of transit-oriented communities has made it easier for residents to access employment, education, and other services without relying on cars.
Another impact of city planning and development on Ontario's cities has been the preservation and enhancement of natural and cultural heritage.

Here's how to put together an insulated inner cover for your beehive without having to buy a new cover or build one. I learned this method from Phillipe at MudSongs.org , he has some great info on his beekeeping site, very down to earth.
An insulated inner cover reduces or prevents condensation in the beehive in winter.
Why does this matter? Condensation is water that collects on the top of the hive. It forms on the side of the inner cover that faces the bees. When enough water collects, it will drip back down onto the bees. Not a good thing.
Wet bees are dead bees.
Especially in winter.
How does this cover help? Condensation happens when warm air meets a cold object. In the beehive in winter, the bee cluster is warm, and there is some humidity in the air. When the warm air from the cluster rises and hits the cold inner cover, the water vapor condenses and drops back onto the bees. Not good.
The insulation that sits on top of the inner cover here keeps the cover from getting real cold, thus reducing or eliminating condensation. Since I have been using the insulated inner cover, I have not seen signs of condensation in the hive. If you find mold in your hives, you have condensation, FYI.
My variation on the insulated cover is to put a shim between the upper super and the inner cover. I then put sugar on top of the frames, using the dry sugar, aka mountain camp, method. This sugar provides a backup food source, and absorbs moisture in the hive.
Be sure the slot of the inner cover is not covered, one should always provide an upper entrance to the hive, plus it allows for air flow. Yes even in cold weather, I believe a hive needs some air flow, so provide an upper entrance. Remember to invert the inner cover.
You should also insulate the sides of the hive.
- Outer cover sits on top of insulation, and usually covers it.
- Insulation - I use 2" thick polystyrene.
- Inner cover, turned upside down, flat side faces upward.
- Spacer shim, with dry sugar on top of newspaper.
- Top brood super
I built some DIY insulated inner covers that are more involved than this stack method, and they work well for me. If you are handy, have at them.


10 Facts About 1950s Singapore That Only Your Ah Ma Will Remember
Singapore In The 50s
Articles about '90s kids' are far too many online. Today, we're going to throw all the way back to a time when our grandparents were young -- the 50s.
Shirtless children running around kampungs defined the spirit of the 50s. It was a decade when people had no care about the paper chase or the 5Cs. The children played bare-foot in the fields while adults crouched at the steps of their attap houses and work was just for feeding the mouths under the same zinc roof.
The 50s also saw the rise of cultural icons that eventually shaped Singapore. Show your grandparents this list and you might be wowed by their memories from pre-independence Singapore.
1. We had privately-owned zoos with 50 cent entrance fees

The west of Singapore has been always the go-to place for wildlife sanctuaries. Long before the Singapore Zoo was the Singapore Miniature Zoo at Pasir Panjang. You might not think much of wildlife preservation in post-war Singapore but the Singapore Miniature Zoo had not only sun bears and lions -- they even had penguins!
Ticketing fees were also cheaper in the past with adults paying 50 cents and children a mere 20 cents.
2. Magnolia's iconic pyramid-shaped milk packets
1950s singapore
This ought to be the fondest memory any child in the 50s had. Free milk was given out in the schools in the quirky shape of a pyramid, unlike the usual rectangular cartons that we now see everywhere. This unique and iconic packaging is one everyone soon started associating with Magnolia.
3. A swimming pool that becomes women-only on Tuesdays

1950s singapore
Being the second public swimming pool in Singapore, it is no wonder that Yan Kit Swimming Pool was always crowded with locals escaping the heat. It was often so jam-packed that there wasn't any room to swim laps and visitors were limited to spending just two hours there.
On Tuesdays, the pool was only opened for ladies who found it immodest to be in their swimsuits among strangers.
4. A scheme for children to save money
1950s singapore
10-cents = one plate of mee rebus. Source
1950s children were taught to save money by buying stamps for 10 cents each, and sticking them on a School Savings Scheme card. Once they've stuck 20 stamps onto the card (for $2 in total), they could trade the card in at the post office and their bank account would be credited with the money. If students had at least $5 in their account at the end of the year, they'd even get an extra $5 from the government.
This was to encourage the habit of saving in small doses!
5. There was a legit reason to squat on chairs in coffee shops

Back when spitting phlegm and chewing tobaccos were everyday habits of the Singaporean uncle, avoiding goops of saliva was easier said than done.

A floor flooded with spit is not a good sight. Source
By placing vases-like containers called spittoons under coffee tables, it wasn't long before people realised that they should start crossing their legs or squatting on the chairs to keep the floor clean.
Maybe this was how we mastered the Asian squat.
6. The Magnolia Ice-Cream man

No child can withstand the bell of the ice cream man. Source
The ice cream man is a familiar sight for us even till today. As Singaporeans, our love for ice-cream in bread is one that has endeared through the generations and through the decades.
In the days of your ah ma, it took on the form of a peddler on his motorcycle with a yellow "ship" connected to it. In the "ship" was the answer to surviving Singapore's weather: rectangular blocks of Magnolia's classic ice-cream. Yasss.
7. Mass weddings were really common

Imagine getting married together with your clique. Source
In those days, being married alongside other couples was a common occasion. In the different dialect guilds and clubs, over 10 couples could get married all on a single day. This trend lasted till the 70s and there were even instances where they'd all go on their honeymoon together!

8. The "OG" of TCM - the "Koh Yok" man
1950s singapore
They're literally 'doctors' on the street corner. Source
If you ever got a bruise and your ah ma asks you to rub some strange-smelling liquid on it, chances are that she learnt that technique from the koh yok man -- the poor man's doctor.
The koh yok man's medical knowledge was not acknowledged by Western medicine but has a long tradition stemming from legit TCM. They struck out a living on the streets by providing medical attention for those who can't afford private doctors. With thwacks here and there, they could even relieve sprains or even joint dislocations.
9. $1 circus shows with wild animals
1950s singapore
Being in a cage filled with wild cats must've been nerve-wrecking.

The tightrope has been a classic act ever since the first circuses. Source
Wild animals in circuses might have been banned in Singapore for more than 10 years but in the 50s, it was all the rage. The Big Tops can be found setting up in any vacant plot of land with the performing animals kept in cages outside them and there'd be 2 shows running every day.
Tigers jumping through hoops, tightrope walkers and gymnasts -- there was entertainment for everyone even in those turbulent times.
10. "Burning the midnight oil" was literal
1950s singapore
A common sight in families of the 50s. Source
This was probably the one thing from their past that hardworking students and busy adults would remember of their sleepless nights. By burning the kerosene-soaked wicks, everyone in the family would be able to work through the night in an otherwise dark home.
The scarcity of electricity in those days meant that every night of 'burning midnight oil' ran the risk of being a fire hazard.
The 1950s Singapore we will never see
Long gone are the circuses and fear of kicking over spittoons but these are nostalgic elements of our grandparents' past that you can talk about to see their eyes sparkle. Talking about the 50s would awaken the same nostalgia in our grandparents as it does for us when someone talks about waking up at 9am to catch our favourite cartoon programmes.
Collect exclusive Magnolia's 80th anniversary memorabilia
1950s singapore
A household name in Singapore since the introduction of the pyramid-shaped pack in the 1950s, Magnolia's been the brand that comes to mind whenever a generation of Singaporeans wanted to buy fresh milk.
With its iconic packaging and involvement in the School Milk Programme, it is no wonder that till today, our ah gong and ah ma remember the classic brand as a major part of their childhood. It was, after all, on a daily basis, that Magnolia brought the nutrition game for the children up a notch.

Dynamic voltage and frequency scaling (DVFS) is an essential mechanism for power saving in smartphones and mobile devices. Central processing unit (CPU) load based DVFS algorithms are widely used due to their simplicity of implementation. However, such algorithms often lead to a poor response time, which is one of the most important factors of user experience, especially for interactive applications. In this paper, the response time is mathematically modeled by considering the CPU frequency and characteristics of the running applications based on the Linux kernel's completely fair scheduler (CFS), and a Response time constrained Frequency & Priority (RFP) control scheme for improved power efficiency of smartphones is proposed. In the RFP algorithm, the CPU frequency and priority of the interactive applications are adaptively adjusted by estimating the response time in real time. The experimental results show that RFP can save energy up to 24.23% compared to the ondemand governor and up to 7.74% compared to HAPPE while satisfying the predefined threshold of the response time in Android-based smartphones.

From Pioneers to Present Day
College Avenue, circa 1898. Photo courtesy Cheney Historical Museum.
Cheney developed into the city we know today because of its strong ties to education, rail, and agriculture. This provided a strong economic base for the community and was the result of much larger events that took place in the United States.
What's in a Name?
The name of the little community, originally Section Thirteen became Willow Springs, then became Depot Springs, because of its ties to the railroad, then Billings, in honor of a president of the Northern Pacific Company, and finally Cheney, in honor of Benjamin P. Cheney, a Director of the Northern Pacific Railroad.
Benjamin P. Cheney was the eldest son of a blacksmith who was born in 1815 at Hillsborough, New Hampshire. Mr. Cheney, a director of the Northern Pacific Railroad, donated $10,000 to establish the Benjamin P. Cheney Academy in the town. And the railroad donated 8 acres of land so that the educational facility could be built.
The County Seat
The Grand Steal
On a night when most of the residents of Spokane Falls were at a gala wedding celebration, a delegation of armed "Cheneyites" invaded the Auditor's office, took possession of the books, did their own ballot recount which showed Cheney the victor, and made off into the darkness with the records - and the auditor, who may have been sympathetic to their position. The "Grand Steal" was not contested and was confirmed by a court decision in 1881.
EWU's Roots: the Benjamin P. Cheney Academy
Shaping a Community
The creation of "Special Interest Groups" was an increasing interest in the social circle. Participating in "proper" social activities became the forefront in Cheney for creating a character all its own. In the past, keeping the small town characteristic was an important issue, and today we find that the citizens of Cheney still share that same ideal and vision for Cheney's future.

The Marquess of Donegall, a former British war correspondent and London newspaper columnist, died Saturday at his home in Switzerland. His age was 71.
Lord Donegall was the sixth holder of the title, which dates to 1612 and originated in County Antrim, Northern Ireland. Named Edward Arthur Donald St. George Hamilton Chichester, he succeeded to the title when he was one year old. With the title went the designations of Governor of Carrichfergus Castle, and Hereditary Lord High Admiral of Lough Neagh. Lough Neagh is a lake 17 miles long and 10 miles wide in Antrim.
After schooling at Eton and Oxford, Lord Donegall became a reporter and later war correspondent and columnist for The Sunday Dispatch of London and moved to Switzerland to avoid what he described as high British taxes.Continue reading the main story

In response to some serious issues like the energy crisis and environmental problems associated with the conventional compression refrigeration system, thermal air-conditioning systems were therefore developed to overcome the mentioned problems. A completely novel integrated adsorption and absorption (AD-AB) refrigeration system driven by low-grade temperature heat sources is proposed in this investigation. This novel cycle focuses on the inherent characteristics of the adsorption and absorption phenomena. The innovation here is that the generator of the absorption cycle becomes the evaporator of the adsorption cycle. Therefore, the generation and evaporating pressure are associated with the heat source temperature. Moreover, the adsorber in the adsorption system replaces the condenser in the standard absorption system. Thus, the generation pressure is associated with the heat source temperature and can be adjusted according to the solution concentration and generation temperature.
Keywords integrated AD-AB system, absorption, adsorption, COP, low-grade thermal energy, energy Efficiency.

Considered by some authorities to be a separate species and by some to be a sub species of Lesser Whitethroat (sylvia curruca) the Hume's Whitethroat is one of those species that occurs in the far southeast of the Western Palearctic as a scarce passage migrant and very occasional winterer. It is treated as a full species by Clements.
This article is based on our experiences of the species from several spring tours to Kuwait. Although not a regular migrant even here it is undoubtedly overlooked to some extent due to poor observer coverage and confusion with Lesser Whitethroat which is a very common spring migrant through the state.
Range – The breeding range of Hume's and Lesser Whitethroat do not overlap. Hume's Whitethroat is an upland breeding species with its range extending from eastern Iran eastwards to the Tian Shan mountains of central Asia and the western fringes of the Himalayas. It breeds at altitudes of 2,000–3,600 m in open scrub, often with juniper, and also in cultivated areas such as almond orchards. It migrates south to southern Pakistan and India in the winter with wintering also having been noted in south Iran. Clearly its spring passage includes Kuwait on the very western edge of its migration route.
Voice – Although unlikely to be heard from a migrating bird this is very different from Lesser Whitethroat being an almost Blackcap-like warble with a slight scratchy quality. The migrant birds we have observed tend to be silent unlike the very vocal Lesser Whitethroats.
The song can be heard here _URL_
Size – When seen alongside a Lesser Whitethroat at Al Abraq in western Kuwait it is clearly a larger more bulky bird with a correspondingly heavier bill. Its movement was also noted to be more ponderous.
Plumage – In comparison with Lesser Whitethroat, Hume's gives an overall darker impression. The mantle is much greyer (especially in 1w birds) as is the nape and crown which means there is no real contrast between head and mantle colour. The crown itself is darker grey than Lesser and the ear coverts are very dark (sometimes appearing almost black) but due to the darkness of the crown the contrast is very much less than in Lesser. 1w birds and some spring birds show a dusky wash on the breast and flanks contrasting with a white throat.
Habits – being a bird of low mountain scrub migrants tend to shun larger bushes and trees, preferring low vegetation. They are also often seen on the ground and in this tend to closely match the behaviour of Menetries's Warbler (sylvia mystacea) which often shares the same areas.

University of Mississippi Center's Role Critical in Quality and Safety of Supplements, Cosmetics
NCNPR globally recognized for expertise in field of botanicals research
In today's age of online shopping and two-day delivery, consumers have more opportunities than ever to try new health-related products. During COVID-19, for example, many individuals began taking immune-boosting supplements.
Recognizing this trend, the National Center for Natural Products Research at the University of Mississippi School of Pharmacy analyzed a sample of these products. The study produced surprising results.
"As a case study, we purchased more than 30 products just to get an idea if they were actually selling what was listed on their product labels," said Amar Chittiboyina, assistant director and principal scientist at the NCNPR. "We found that around 30% have nothing to do with what they list on their label.
"The internet gives people a lot of accessibility to dietary supplements like multivitamins, pre-workout products, whey protein and even probiotics. We have seen, however, that this is not always a good thing."
The U.S. Food and Drug Administration looks to experts at the NCNPR to assess the quality and safety of products such as these. The research center contains the nation's only FDA Center of Excellence dedicated to this work.
"We could rapidly pull together the COVID-19 study because we have developed the resources to do so over the past 20 years," Chittiboyina said. "That includes our research leadership, botanical reference material, state-of-the-art instrumentation and expertise – our people."
Under the leadership of NCNPR Director Ikhlas Khan, the Center of Excellence resulted from a partnership with the FDA that began in 2001. It is charged with developing analytical methods and reference standards for botanical formulations sold as dietary supplements in the U.S.
The Center of Excellence aids the FDA's Center for Food Safety and Applied Nutrition in fulfilling its public health mission.
"At the end of the day, we want to make sure that the science is there to confirm that the product contains what it says on the label for various reasons," Chittiboyina said. "Most of these products are consistent with their label; however, a good number of samples may not include what they claim to contain."
To do this, the NCNPR partners with botanical gardens around the globe to source plant materials that they use to validate the authenticity of botanical raw materials found in dietary supplements. Outside of the university's own Maynard W. Quimby Medicinal Plant Garden, the center has various international collaboration agreements.
Cosmetics research, specifically in regard to botanical-based cosmetic products, is yet another area where the NCNPR is a recognized leader.
"Botanical extracts and single ingredients are increasingly used in cosmetics and other personal care products," Chittiboyina said. "The center's resources allowed us to develop a unique lab-based method that is now patented and can be used by manufacturers for the safety assessment of botanical raw materials in various cosmetic products.
"It is important for manufacturers to substantiate the safety of both ingredients and finished cosmetic products prior to marketing to the public."
Traditional plants, such as cinnamon, have been used for their health-improving properties for thousands of years, said Ahmed Osman, senior research scientist.
"That's the basis for the emergence of dietary supplements," Osman said. "These ingredients that have been used in China or India or the U.S. have proven medicinal benefits.
"Most of the botanicals are safe; however, we thrive on generating reliable scientific tools for quality assurance – especially with the modern form of supplements."
Bill Gurley, principal scientist, called the NCNPR the "best kept secret on campus." He has collaborated with the center for 20 years in various roles.
"We are the premier entity that can provide both research and information regarding dietary supplements," Gurley said. "Anytime there's a nationally recognized issue regarding these products, they come to us."
When selecting products, consumers can stay informed of safety issues by using resources already available to them, Chittiboyina said.
"It's a daunting task to determine which product to trust because there are so many options out there," he said. "But consumers can be pragmatic – they can look up the company history and the claims to see what's realistic and make an educated choice; nowadays, so many resources are at the consumer's fingertips."

in this way: host$ virsh start --console vsockguest ncat like It's possible to use socat like ncat, transferring stdin and stdout via VSOCK. Guest listening In this example we start socat in the guest listening on port 1234: guest$ socat - VSOCK-LISTEN:1234 Then we connect from the host using the CID 42 assigned to the VM: host$ socat - VSOCK-CONNECT:42:1234 At this point we can exchange characters between guest and host, since stdin and stdout are linked through the VSOCK socket. Host listening In this example we do the opposite, starting socat in the host listening on port 1234: host$ socat - VSOCK-LISTEN:1234 Then, in the guest, we connect to the host using the well defined CID 2. It's always used to reach the host: guest$ socat - VSOCK-CONNECT:2:1234 ssh over VSOCK The coolest feature of socat is to concatenate sockets of different address families, so in this example we redirect ssh traffic through VSOCK socket exposed by the VM. This example could be useful if the VM doesn't have any NIC attached and we want to provide some network connectivity, like the ssh access. First of all, in the guest we start socat linking the VSOCK socket listening on port 22, to a TCP socket which will connect to the local TCP port 22 where the ssh server is listening: guest$ socat VSOCK-LISTEN:22,reuseaddr,fork TCP:localhost:22 On the host we link a TCP socket listening on a port of our choice (e.g. 4321) to the guest port 22 just opened using VSOCK: host$ socat TCP4-LISTEN:4321,reuseaddr,fork VSOCK-CONNECT:42:22 Finally from the host we can connect to the guest using ssh on the local port 4321, where socat is listening: host$ ssh -p 4321 root@localhost socat redirects all the traffic between the sockets and allow us to use ssh over VSOCK to reach the guest. Fri, 22 Jan 2021 14:16:04 +0000 (Stefano Garzarella) QEMU project: Configuring virtio-blk and virtio-scsi Devices The previous article in this series introduced QEMU storage concepts. Now we move on to look at the two most popular emulated storage controllers for virtualization: virtio-blk and virtio-scsi. This post provides recommendations for configuring virtio-blk and virtio-scsi and how to choose between the two devices. The recommendations provide good performance in a wide range of use cases and are suitable as default settings in tools that use QEMU. Virtio storage devices Key points Prefer virtio storage devices over other emulated storage controllers. Use the latest virtio drivers. Virtio devices are recommended over other emulated storage controllers as they are generally the most performant and fully-featured storage controllers in QEMU. Unlike emulations of hardware storage controllers, virtio-blk and virtio-scsi are specifically designed and optimized for virtualization. The details of how they work are published for driver and device implementors in the VIRTIO specification. Virtio drivers are available for Linux, Windows, and other operating systems. Installing the latest version is recommended for the latest bug fixes and performance enhancements. If virtio drivers are not available, the AHCI (SATA) device is widely supported by modern x86 operating systems and can be used as a fallback. On non-x86 guests the default storage controller can be used as a fallback. Comparing virtio-blk and virtio-scsi Key points Prefer virtio-blk in performance-critical use cases. Prefer virtio-scsi for attaching more than 28 disks or for full SCSI support. With virtio-scsi, use scsi-block for SCSI passthrough and otherwise use scsi-hd. Two virtio storage controllers are available: virtio-blk and virtio-scsi. virtio-blk The virtio-blk device presents a block device to the virtual machine. Each virtio-blk device appears as a disk inside the guest. virtio-blk was available before virtio-scsi and is the most widely deployed virtio storage controller. The virtio-blk device offers high performance thanks to a thin software stack and is therefore a good choice when performance is a priority. It does not support non-disk devices such as CD-ROM drives. CD-ROMs and in general any application that sends SCSI commands are better served by the virtio-scsi device, which has full SCSI support. SCSI passthrough was removed from the Linux virtio-blk driver in v5.6 in favor of using virtio-scsi. Virtual machines that require access to many disks can hit limits based on availability of PCI slots, which are under contention with other devices exposed to the guest, such as NICs. For example a typical i440fx machine type default configuration allows for about 28 disks. It is possible to use multi-function devices to pack multiple virtio-blk devices into a single PCI slot at the cost of losing hotplug support, or additional PCI busses can be defined. Generally though it is simpler to use a single virtio-scsi PCI adapter instead. virtio-scsi The virtio-scsi device presents a SCSI Host Bus Adapter to the virtual machine. SCSI offers a richer command set than virtio-blk and supports more use cases. Each device supports up to 16,383 LUNs (disks) per target and up to 255 targets. This allows a single virtio-scsi device to handle all disks in a virtual machine, although defining more virtio-scsi devices makes it possible to tune for NUMA topology as we will see in a later blog post. Emulated LUNs can be exposed as hard disk drives or CD-ROMs. Physical SCSI devices can be passed through into the virtual machine, including CD-ROM drives, tapes, and other devices besides hard disk drives. Clustering software that uses SCSI Persistent Reservations is supported by virtio-scsi, but not by virtio-blk. Performance of virtio-scsi may be lower than virtio-blk due to a thicker software stack, but in many use cases, this is not a significant factor. The following graph compares 4KB random read performance at various queue depths:

Saudi Arabia has been working with the U.S. space agency NASA in
lunar and asteroid science research. Officials said a recent accord with the
King Abdulaziz City for Science and Technology, or KACST, recognized the
Saudi Lunar and Near-Earth Object Science Center as an affiliate partner
with the NASA Lunar Science Institute.
"We are looking forward to our expanding collaboration with
NASA for the benefit of both countries," KACST vice president Turki Bin Saud
Bin Mohammed Al Saud said.

In 2008, Saudi Arabia and the United States signed a memorandum of
understanding for cooperation in science and technology. Under the accord,
the two countries would conduct joint projects and Saudi scientists would
train in the United States.
"Our continuing discussions with Saudi Arabian officials may lead to
future joint scientific collaboration in other areas of mutual interest,"
NASA assistant administrator Michael O'Brien said.
Officials said the Saudis would work with NASA in such research as radar
and infrared imaging, laser ranging and imaging, and topography. They said
the Saudi Lunar and Near Earth Object Science Center would direct all lunar
and near Earth object-related research in the kingdom.
"It will reach out to students in addition to researchers and present

It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch' and such.

Definition - What does Home Key mean?
The Home key is a key found on most physical and virtual keyboards and is supported by most operating systems. The Home key is supported by certain software applications as well. The primary functionality of the Home key in most applications is to return the cursor to the beginning of a line, document, page, screen or worksheet cell based on the position of the cursor.
Techopedia explains Home Key
The Home key helps in navigation of applications or a word processing programs. It is most commonly used to make the cursor move to the beginning of the line in a text editing program. The Home key has the opposite functionality of the End key.
Keyboards which do not have a Home key, usually due to limited size, can achieve the same functionality with the combination of a function key and the left arrow key. If a document is not editable, the Home key can help in scrolling the scrollable document to the beginning in operating systems like Microsoft and Linux. This is in addition to the functionality involving text editing applications, where the Home key can help return the cursor to the beginning of the document or the current line. Along with other function keys, the Home key can provide different functions like selecting all characters in a selectable text before the cursor, by pressing a combination of the Home and Shift keys simultaneously. In software applications, the Home key can have different functions such as reaching the menu screen.

- Portions of the Matlab program execute in light of the client input, comes about are shown, what's more, the program sits tight for extra client input.
- When an order is entered that doesn't meet the charge governs, a mistake message is shown. The revised order would then be able to be entered.
- Use of this condition doesn't require the accumulate connect/stack execution process depicted above for abnormal state dialects. While this intuitive, line-by-line execution of Matlab orders is advantageous for straightforward computational errands, a procedure of readiness and execution of projects called contents is utilized for more confounded computational assignments:
- A content is rundown of Matlab summons, arranged with a word processor.
- Matlab executes a content by perusing a summon from the content record, executing it, and after that rehashing the procedure on the following order in the content document.
-Errors in the punctuation of an order are recognized when Matlab attempts to execute the summons. A punctuation blunder message is shown and execution of the content is stopped.
- When sentence structure mistakes are experienced, the client must alter the content document to remedy the blunder and afterward coordinate Matlab to execute the content once more.
- The content may execute without language structure blunders, yet deliver inaccurate outcomes when a rationale mistake has been made in composing the content, which likewise requires that the content be altered and execution re-started.
- Script arrangement and investigating is along these lines like the order connect/stack execution process required for in the advancement of projects in an abnormal state dialect.

Additionally confounding the investigator's part is the way that the framework is frequently so nonlinear that the best way to comprehend it is through recreation. Land based power age from hydroelectric, steam or different gadgets are not by any means the only utilization of energy frameworks. A typical quality of these frameworks is their utilization of energy gadgets and control frameworks to accomplish their execution destinations.
SIMULINK is a product bundle for displaying, mimicking, and breaking down dynamical frameworks. It underpins straight and nonlinear frameworks, displayed in constant time, inspected time, or a half and half of the two. Frameworks can likewise be multi rate, i.e., have distinctive parts that are examined or refreshed at various rates. For modelling, SIMULINK gives a graphical UI (GUI) for building models as piece outlines, utilizing snap and-drag mouse tasks. With this interface, you can draw the models similarly as you would with pencil and paper (or as most reading material dearduinot them). This is a long ways from past simulation bundles that expect you to detail differential conditions and contrast conditions in a dialect or program. SIMULINK incorporates a far reaching piece library of sinks, sources, straight and nonlinear parts, and connectors. You can likewise tweak and make your own particular pieces. Models are progressive, the models are fabricated utilizing both best down and base up approaches the framework can saw at an abnormal state, at that point double tap on squares to go 5 down through the levels to see expanding levels of model detail.
This approach gives understanding into how a model is sorted out and how its parts interface. After a model is characterized, it can reproduce, utilizing a decision of mix strategies, either from the SIMULINK menus or by entering orders in MATLAB's summon window. The menus are especially helpful for intelligent work, while the summon line approach is extremely valuable for running a bunch of reproductions. Utilizing extensions and other show obstructs, the simulation results can see while running.
SimPowerSystems and SimMechanics of the Physical Modelling item family cooperate with Simulink to show electrical, mechanical and control frameworks. SimPowerSystems is an advanced device that enables researchers and designers to quickly and effectively fabricate models that mimic power frameworks. SimPowerSystems utilizes the Simulink condition, permitting building a model utilizing basic snap and drag techniques. Can draw the circuit topology quickly, as well as examination of the circuit can incorporate its connections with mechanical, warm, control, and different orders. This is conceivable in light of the fact that all the electrical parts of the simulation interface with the broad Simulink displaying library. Since Simulink utilizes MATLAB as its computational motor, creators can likewise utilize MATLAB tool compartments and Simulink piece sets. SimPowerSystems and SimMechanics share a unique Physical Modelling piece and association line interface.
The simulation is finished utilizing MOSFET switches and control signals like Pulse Width Modulation.

Abstract
The aim of the present study was to determine whether the difference in maximal voluntary contraction (MVC) forces between unilateral (UL) and bilateral (BL) contractions could be due to a difference in the timing of MVC peak force production between legs during BL MVC, or due to the maximal voluntary activation level (VAL) in each leg between UL and BL MVC. Thirteen active men (28 ± 6 years) volunteered to participate in an experimental session requiring the performance of MVC with right, left and both knee extensor muscles. An ergometer equipped with two strain gauges was used to assess the timing of MVC peak force production of each leg during BL MVC. Transcutaneous electrical stimulation was used to investigate VAL and electromyography (EMG) activity. The present results showed that the sum of the right and left UL MVC was higher compared to BL MVC force, i.e., a BL deficit of force. The timing of MVC peak force production of each leg during BL MVC was not different, but BL MVC force was lower than the sum of BL MVC(R) and BL MVC(L) force (i.e., maximal force production of each leg during BL MVC). No changes of EMG activity, M-wave amplitude, VAL, and peak doublet between UL and BL contractions were observed. The difference found in the production of force during BL MVC cannot be explained by the timing of force production of each leg.

Lambic beer is the oldest style of beer still being produced in the Western world using spontaneous fermentation. Gueuze is a style of lambic beer prepared by mixing young (one year) and older (two to three years) beers. Little is known about the volatiles and semi-volatiles found in commercial samples of gueuze lambic beers. SPME was used to extract the volatiles from nine different brands of lambic beer. GC-MS was used for the separation and identification of the compounds extracted with SPME. The pH and color were measured using standard procedures. A total of 50 compounds were identified in the nine brands. Seventeen of the 50 compounds identified have been previously identified. The compounds identified included a number of different chemical groups such as acids, alcohols, phenols, ketones, aldehydes, and esters. Ethyl acetate, 4-ethylphenol, and 4-ethylguaiacol are known by-products of the yeast, Brettanomyces
, which is normally a spoilage microorganism in beer and wine, but important for the flavor characteristics of lambic beer. There were no differences in pH, but there were differences in color between the beer samples.

The village of Grayslake today has lifted a precautionary water boil that went into effect Wednesday.
For nearly two days, residents had to boil their water after the water system lost pressure, likely due to the stress of the extreme weather on equipment.
The village water system lost pressure around 12:30 p.m. Wednesday due to a telemetry system malfunction, possibly caused by the extreme cold that began Monday. Village crews responded by overriding the automatic operating system and manually flipping the switch to start pumping water back into the system. Normal water pressure was restored in less than 30 minutes.
Bill Heinz, director of public works and village engineer, said the telemetry system is a computer system that controls pumps on water systems, both fresh water and sewage, and reacts to what sensors tell it. Sensors in the water system apparently froze and the water level got down to a point where the water pressure was compromised. If the pressure goes too low, contaminates can find their way into the system.
Due to the loss in pressure, the village is required by the Illinois Environmental Protection Agency, to issue a water boil order for residents.

To create new dynamic programs during the runtime of an ABAP/4 program, you must use an internal table. For this purpose, you should create this internal table with one character type column and a line width of 72. You can use any method you like from Filling Internal Tables to write the code of your new program into the internal table. Especially, you can use internal fields in which contents are dependent on the flow of the program that you use to create a new one, to influence the coding of the new program dynamically. The following example shows how to proceed in principal:
DATA CODE (72) OCCURS 10.
APPEND 'REPORT ZDYN1.'
APPEND 'WRITE/"Hello, I am dynamically created!".'
Two lines of a very simple program are written into the internal table CODE.
In the next step you have to put the new module, in the above example it is a report, into the library. For this purpose you can use the following statement:
INSERT REPORT FROM .
The program is inserted in your present development class in the R/3 Repository. If a program with this name does not already exists, it is newly created with the following attributes:
Type: 1 (Reporting),
Application: S (Basis).
You can specify the name of the program explicitly within single quotation marks or you can write the name of a character field, which contains the program name. The name of the program must not necessarily be the same as given in the coding, but it is recommended to do so. is the internal table containing the source code. For the above example you could write:
INSERT REPORT 'ZDYN1' FROM CODE.

Axon guidance requires interactions between extracellular signaling molecules and transmembrane receptors, but how appropriate context-dependent decisions are coordinated outside the cell remains unclear. Here we show that the transmembrane glycoprotein Dystroglycan interacts with a changing set of environmental cues that regulate the trajectories of extending axons throughout the mammalian brain and spinal cord. Dystroglycan operates primarily as an extracellular scaffold during axon guidance, as it functions non-cell autonomously and does not require signaling through its intracellular domain. We identify the transmembrane receptor Celsr3/Adgrc3 as a binding partner for Dystroglycan, and show that this interaction is critical for specific axon guidance events . These findings establish Dystroglycan as a multifunctional scaffold that coordinates extracellular matrix proteins, secreted cues, and transmembrane receptors to regulate axon guidance.


OBIEE - Which Usage Tracking time measure should be used to gauge the performance of SQL retrieval time ?
2 - Measures
2.1 - TOTAL_TIME_SEC
TOTAL_TIME_SEC is the same as Response time in the query log. It is the response time for the execution of a logical request in the gateway. There are several times from the query log that are included in response time (TOTAL_TIME_SEC) that are not tracked in the usage tracking logs.
TOTAL_TIME_SEC is the time that the OBI server spent working on a query. This includes the clock time spent waiting for queries to complete.
If multiple physical queries are running in parallel, the time reported is how long OBI is spent waiting for the database. This basically is the run time of the longest running query.
The total time of all physical queries spawned by a single logical query is reported in CUM_DB_TIME_SEC. This is not part of TOTAL_TIME_SEC. Time spent waiting for resources is not included in TOTAL_TIME_SEC.
TOTAL_TIME_SEC is the time clocked once the request reaches nqsserver. Any wait for connections would happen before the request reached nqsserver. These would be reflected in the difference between START_TS and END_TS as mentioned above.
2.2 - START_TS and END_TS
Note also that START_TS and END_TS have nothing at all to do with TOTAL_TIME_SEC.
START_TS is the time when a BI Server Client submits a query.
For Presentation Service, this could happen when you hit the Results tab in Answers or when you select a dashboard page.
END_TS is when the results are returned to the client.
The difference between START_TS and END_TS also includes any time spent waiting for resources, such as waiting for a free connection.
3 - CUM_DB_TIME_SEC
The CUM_DB_TIME_SEC column sometimes show a value greater than TOTAL_TIME_SEC.
CUM_DB_TIME_SEC is the cumulative time of all of the queries sent to the backend database. These queries run in parallel so the cumulative query time will be equal to or greater than the total time connected to the database. Say for example that a logical request spawns 4 physical SQL statements sent to the database and that the query times for 3 of the queries are 10 seconds and one is 15 seconds. Since the queries run in parallel, nqsserver will only be connected to the backend database for 15 seconds. CUM_DB_TIME_SEC will show 45 seconds.
4 - Waiting Time and parallelism
Not true !
TOTAL_TIME_SEC = END_TS - START_TS
TOTAL_TIME_SEC = COMPILE_TIME_SEC + CUM_DB_TIME_SEC
The reasons why the calculations provided above do not add up are because:
 - The processes are carried out in parallel and is very much dependent on the load on the BI Server and database performance.
 - If all connections are full then the query would join a queue and wait.
This dependent on the load and configuration of the execution so it won't add up.
 - Under normal circumstances the process will take place parallel and engenders server based operations that are light or intensive.
For instance, if TOTAL_TIME_SEC is 0 but the difference between START_TS and END_TS is 14 minutes, the 14 minutes could have been spent waiting.
If it is evident that a SQL is delayed, it is because it is waiting for:
Connection pooling is also handled by nqsserver, not sawserver.

The DataPortal Query module allows querying of data in a Composable DataPortal using Entity SQL. It takes a DataPortal ID, an SQL query, and a list of objects as parameters and returns a Composable Table.
See below for a complete discussion of inputs and options.
The following example DataFlow demonstrates many of the possible ways to use the DataPortal Query module. This DataFlow uses the DataPortal Query sample DataPortal model, which creates a DataPortal called
DataPortalQuery by default. WARNING: this DataFlow deletes all existing data in the DataPortal, so only run it against a test DataPortal. You can change the name in the Excel file if you already have a
DataPortalQuery DataPortal, just be sure to select the right DataPortal when configuring the DataFlow.
Adding New Data
This DataFlow uses the DataPortal Sync module to add entries to the DataPortal we can query from. These will create 5 entries, each having two FamilyHistoryEntries.
Querying Data Using Entity SQL
To ensure the proper types are returned if the query produces no data, it is usually best practice to not use the VALUE keyword. The module will provide a warning if the user attempts to use it and no data is returned. The recommended way of returning all data from a table is as shown below:
There is no '*' selector in Entity SQL. If you want all the rows to be returned in a query you must manually specify them. For a full list of the differences between Transactional SQL queries and Entity SQL queries refer to the official documentation.
The output of the DataPortal Query module is a Composable Table. If the object is a one-to-one relationship such as Double, the value will simply be returned as it exists in the database. If the object is a one-to-many relationship in the case of FamHistoryEntries which is a Table, an error will be thrown. To reference these write a SQL query like the one shown here that joins the tables:
This is the Id for the DataPortal you wish to query. Simply click on it and select the DataPortal from the list that appears.
This is the SQL query you wish to execute on the DataPortal. Specific formatting can be found in the example.
This takes in a list of KeyValuePairs of type
Cases AS c
FamilyHistories AS h
ON c.Id = h.CaseId
WHERE h.HasFamilyHistory = _USER_
