This exhibition offers visitors a glimpse into the lives of the Delaware Indians over a two hundred year time span. From the 1740s to the 1890s, many of New Jersey's Indians moved out of the state ahead of the ever-expanding non-Indian population. Artist and chronicler of American Indians, George Catlin (_PHONE_), noted as early as 1832 that the Delaware were among the most relocated Indians in the United States. This exhibition tells the story of these migrations.
In the late 1800s and into the 1900s, the Indians that remained in New Jersey survived by adapting to a market economy. They developed handcraft industries which produced items desired by non-Indian settlers. The Indians produced baskets and other woven items such as mats and brooms, as well as carved wooden pieces such as mortars and shovels.
The descendents of the Delaware Indians who left New Jersey, as well as those who stayed, continue to follow and adapt their cultural and religious traditions, thus preserving them for future generations and sharing them with all other cultures.
The objects on view, which date from the late 1700s to the early 1900s, include a woman's blouse with silver brooches, splint baskets, a wooden shovel, a leather pipe bag decorated with glass beads, children's moccasins and a child's basket.
The exhibition was made possible through funding support provided by PSEG Foundation, with additional generous support provided by the Friends of the New Jersey State Museum.

Simple Batik Instructions
Batik Instructions for Soy Wax
By: Colorado Wholesale Dye
These are simple instructions with soy wax and pipettes. This method won't work with other waxes as they have higher melting points and require other methods of removal. The proper way to batik is with a batik pen (a Tjanting Tool) but this works just as well if you don't have one available.
What you need:
-Soy Wax -Dye
-Pipettes -Dye Fixer (Soda Ash)
- Melt the wax. Soy wax has a low melting point so it can be melted in the microwave or in a double boiler with some hot water.
2. Apply the wax to your fabric using a pipette. Use caution and gloves as Pipette will get hot from the wax and you don't want to get burned!
(Tip: Make sure to put cardboard or something between the fabric otherwise the wax will soak through and create a resist on the other side of the fabric as well)
3. Wait for the wax to dry completely.
4.Soak the fabric in dye fixer. Use warm water, but not too hot. If the water is to hot it could re-melt the wax and mess up your design.
5. Ring the fabric out and tie it up in the design you wish to achieve.
6. Dye the fabric and then let it sit for anywhere from 3 hours to 24 hours. The length of time you let it sit affects how easy the fabric is to wash out. The longer it is left alone the less loose dye will flow out and the shorter it will be to wash out.
7. Rinse the fabric under COLD running water. Keep rinsing until the water is flowing clear and all the loose dye is washed out.
8. When all the loose dye is rinsed out run the fabric under HOT running water. This will melt the wax and wash it away from the fabric. Do NOT rub the wax to help get it off, this will just spread the wax around and muddy up the design. Just let the hot water run over it and it will all wash away.
9. When the wax is all washed away, wash and dry the fabric as normal.

Vision -Three Stages in Environmental Conservation ActivitiesThe Ricoh Group's environmental conservation efforts have evolved through three stages that we define as the "passive stage," "proactive stage" and "responsible stage." In the passive stage, our efforts generally aimed at addressing external requirements by dealing with laws and regulations and competing with other companies. In the next proactive stage, we began to take voluntary actions with a sense of mission as a global citizen. In the current responsible stage, we have enhanced out efforts to an advanced level, namely, from the stage of simply operating its business in an environmentally friendly manner to pursuing both environmental conservation and profit generation simultaneously. Based on this concept of sustainable environmental management, we are continuing environmental conservation efforts in an integrated part of out business activities. Specific initiatives implemented range a broad areas from developing energy-saving products, curtailing costs by promoting resource/energy conservation, to developing materials that can replace natural resources at a high risk of depletion, and offering efficient and environmental work style-related solutions by providing products and services designed to achieve increased operational efficiency and reduced environmental impact.
In order to effectively protect the global environment and build sustainable societies, it is imperative to reduce impact of human activities on the environment to a level that the Earth's self-recovery capabilities can manage. With this recognition, the Group organizes and participates in a variety of forest ecosystem conservation projects, in addition to efforts to reduce environmental impact stemming from its operations, aiming to improve the self-recovery capabilities of the global environment.

This patent production line of rice bran pretreatment and expansion machines adopts reasonable designs. It can make high efficient expansion for rice bran. This rice bran oil expansion pretreatment is featured by high quality rice bran expansion, low human and production cost, small footprint, low power consumption etc.
Process flow of Rice Bran Oil pretreatment & Expansion introduction:
1. Rice bran was unloaded into workshop manually through artificial screw feeder and then be sent to elevator.
2. The uploaded rice bran goes through rice bran separating screen in order to remove large complexes of rice bran.
3. Clearly cleaned rice bran is sent into quenching pot through elevator conveyor. The quenched rice bran goes into feeding auger after expansion and fall into extruder.
4. After extruding, rice bran expansion materials fall on flat dryer for drying. The dry extruding rice bran is sent to extraction plant by conveyor.
Process Flow Chart of Rice Bran Oil Expansion & Pretreatment:
Working Principle of rice bran oil pretreatment and Expansion:
Rice bran oil expansion pretreatment will change the shape and structure of rice bran through press and promotion of non-isometric and nonstandard screw system of extruder. The gas among rice bran gap is squeezed out and quickly filled with materials, which causes rice bran sheared back and increased pressure inside the chamber. Rice bran hybrid is fully mixed, squeezed, heated, glued and pasted with increasing friction between screw and chamber, which changes rice bran structure and destroys rice bran fat layer structure.
At the same time, mechanical energy converts into heat, and machine chamber quickly rises to 125 degrees, which causes effective passivation of various enzyme activities of rice bran, and destruction of fat layer structure. The starch and protein turn into viscous state while rice bran is extruded to the exit, and high pressure changes into atmospheric pressure instantaneously. Moisture is evaporated from rice bran organizational structure quickly, forming into numerous pore structure inner rice bran. The rice bran oil expansion pretreatment is completed after cooling.

If there is a case were a client would like to combine an exception rule to a transaction type, say for a non-billable number, but still needs to have the transaction amount over a certain value approved first before it exports to billing, both rules can be used together.
In this example, the client would like any transaction marked as an exception when using matter 999999, but also want any postage transaction over $20.00 approved first. Therefore, the transaction would first have to be corrected by the end user, then the transaction needs to be approved by a manager.
- If there is an exception rule for the matter 999999 under ANY TYPE transaction, you need to remove it.
- Then create the exception rule under EACH transaction type, using a different name for each instance, i.e. Fax Exception 999999, Copy Exception 999999, etc.
- Now, under the transaction type that requires approval, highlight the new exception rule and move it to Priority 1. The Requires Approval should be Priority 2 or lower.
- What will happen now is that any Postage transaction with matter 999999 and over $20.00 will first be marked as an Exception and have to be corrected to a valid matter number. It will then move from Exceptions to Requires Approval and need to be approved to Valid before it can be exported.

The Quiet Ensemble sees music everywhere in nature.
"Quintetto" is an installation based on the study of casual movement of objects or living creatures used as input for the production of sounds. The basic concept is to reveal what we call "invisible concerts" of everyday life. The vertical movements of the 5 fishes in the aquariums is captured by a video camera, that translates (through a computer software) their movements in digital sound signals. We'll have 5 different musical instruments creating a totally unexpected live concert.

Design, Conformance Verification, and Performance Evaluation of OpenFlow Message Layer
MetadataShow full item record
The message layer is a critical part of a network protocol stack. The quality of the protocol implementation is closely tied to that of the message layer. The responsibilities of the message layer include conversion between binaries from the network interface and message structures in the device memory, along with validation of these messages. Design and implementation of the message layer pose major challenges, especially for modern protocols that have complex message structures. Poor design choices and errors in the implementation lead to safety issues, performance inefficiencies, and expose vulnerabilities, opening door to potential exploitations and attacks. In this thesis we develop a systematic approach to design and implementation of efficient and correct-by-construction message layer components of the protocol stack. To achieve this goal, we identify some common design trade-off s and evaluate their impacts on performance and/or safety using the OpenFlow protocol as a case study. A performance benchmarking framework leveraging existing tools is developed to conduct these evaluations. Furthermore, the thesis develops a framework for conformance verification. The conformance framework proposes a methodology that generates test messages to identify vulnerabilities in the message layer. In particular, we present an algorithm that minimizes the number of required test messages by exploiting the structure of the message format. A safe message layer is developed as part of the Flowgrammmable OpenFlow stack. Flowgrammable and several existing OpenFlow stack implementations, such as Beacon Controller and CPqD Soft Switch, are evaluated using both proposed conformance and performance frameworks. It is shown that unlike Flowgrammable, implementations of Beacon and CPqD Soft Switch message layer contain conformance violations. Furthermore, design choices such as omitting semantic checking, inlining small and frequently used functions, and header optimization can yield performance gain in protocol stack implementations. The work can be extended by automating the message layer implementation and testing by using a programming language approach. Even though OpenFlow is used as an example, the work can be applied to improve the performance and level of conformance in other network protocols as well. This thesis intends to help developers take a more systematic approach and make better design choices in implementing a conformant message layer for a broad range of network protocols.

- Views: Nippon × Fashion: Local Looks
- Kawamata, Fukushima Prefecture
- The World's Thinnest Silk Wins a Global Following
From just after Japan's opening to the West in the late Edo period (1603–1868) through the 1960s, silk was the nation's representative export. Today demand for Japanese silk has fallen due to cheaper silk from other countries and synthetic fabrics, but the town of Kawamata in Fukushima Prefecture—one of Japan's silk centers—is aiming to revitalize Japanese silk production using world-class technology.
The World's Thinnest Fabric
The supple Fairy Feather silk developed in Fukushima Prefecture's town of Kawamata, one of Japan's most renowned silk production centers, is the thinnest in the world, and so light that it feels like a concentrated layer of air—perhaps even as thin as the legendary hagoromo, or feather mantle, from Japanese folk tales. Fairy Feather is made from 8-denier silk microfibers that are only one-sixth as thick as a human hair (about 50 deniers). This organdie (an ultrathin, plain-woven, sheer fabric), woven on a loom from thousands of silk microfiber warp threads, is so light that it feels nearly weightless to the hand. The softness of such a thin cloth envelops the skin gently and surely.
Kawamata's Fairy Feather is said to be the thinnest silk in the world. The technology enabling industrial production of this fabric has won high praise, including the Prime Minister's Prize, the highest honor at the 2012 Monozukuri Nippon Grand Awards. Although silk production is one industry that has been moving overseas, Fairy Feather continues to attract attention as a globally competitive product.
Birthplace of the "Yokohama Scarf"
The town of Kawamata has been known for producing thin silk since ancient times. According to legend, Otehime, the empress-consort of Emperor Sushun (r. 587–92), fled to Kawamata after the emperor was assassinated in 592. There she propagated the arts of sericulture, or silkworm cultivation, and weaving. A text from the mid-seventeenth century says that Kawamata was already widely known as a silk town, and the region began exporting the product internationally in the 1880s.
The manufacture of silk scarves boomed in the port city of Yokohama, and "Yokohama scarves" became famous worldwide, even for a time holding an 80% share of the global market. Almost half of these so-called Yokohama scarves were actually made from cloth produced in Kawamata.
Fujiwara Kazuichi, head of the Fukushima Prefecture Textile Industry Association, is an authority on the history of Kawamata and its key product. "Sheerness has always been a property of Kawamata silk," he notes. "Since it was sheer and of high quality, by 1884—just after the Meiji Restoration in 1868—it was already being exported via Yokohama. The selection of Fukushima as the location for the first Bank of Japan branch in the Tōhoku region was because it was a trading center for the raw silk and silk products that were at the time a major export of Kawamata. As the financial center of Tōhoku, it also saw a lot of foreign currency coming in from overseas sales of that silk. But today, production volume has fallen to only one-tenth of what it was at its peak."
A Return to Success for the Industry
Fairy Feather was the technical achievement that turned the depressed Kawamata silk industry back into a success story. This textile was developed by Saiei Orimono Co., Ltd., which was founded 60 years ago. President Saitō Yasuyuki says that the name was based on "the image of a feathery curtain of heat haze in the air, thin enough to blow away in a gentle breeze." The cloth features warp and weft threads in alternating colors, creating just the iridescent fabric that the company first envisioned when it set out to create it.
Funding for development of the world's thinnest silk came from various sources, including the Ministry of Economy, Trade, and Industry, which designated it as a Local Resource Support Project. The silkworm cocoons used as raw materials for the thread are a specially chosen variety. Silkworms usually spin their cocoons after molting four times, but the silk used in Fairy Feather is from a variety called sanminsan, meaning "thrice-sleeping silkworm." Cocoons produced after just three moltings are smaller, but the silk fibers they provide are as thin and elastic as spider silk. The higher cost of producing this silk in volume means there are few companies using it, though.
Saitō explains the reason Saiei Orimono opted for a type of thread that other companies were hesitant to use: "Light, thin fabrics are very popular in the fashion industry right now. Katsura Yumi, a wedding dress designer we've done business with for thirty years, told us that she wanted to make dresses that would feel so light on the bride that she'd be able to dance with ease."
The company made unique improvements to its looms, enabling them to weave cloth from sanminsan microfiber silk threads in large quantities, but to also avoid stressing the ultrathin threads, leading to split threads or fluffiness. This strict control of thread tension is what allowed Saiei Orimono to commercialize Fairy Feather.
Success in Paris and Milan
Saiei Orimono also worked to further develop its overseas business. It had been exporting silk for the American bridal market for about twenty years, but exports dropped after the 2008 financial crisis. The firm used that as an opportunity to widen its sales channel to the European apparel market. The first step was participation in a trade fair held in Milan by JETRO, the Japan External Trade Organization. The positive response—and the fact that this was a product that needed to enter the European market in earnest—led the company to apply for JETRO's Customized Export Project Support Program, for which it were selected. After displaying its wares at February 2012 trade fairs held in Paris and Milan, Saiei Orimono received sample orders from several famous international brands. Following that, local papers reported that the company's fabric had been chosen by Giorgio Armani.
"Much time and many hands are needed before we can make a product and put it on sale. We could not have completed Fairy Feather without the generous assistance of the company dyeing the thread, the company that twists the thread, and the company that refines the cloth. Since the disaster we have all gotten used to hearing the word kizuna, the social bonds that tie us together. I believe that this fabric is truly a grand culmination of kizuna," Saitō says enthusiastically.
Saitō's dream is for his company's cloth to be used in theater costumes—and not just any drama houses, but those with tradition on the level of the Paris Opera. How high can this dream fly with wings of Fairy Feather? At a time when Japan-made silk scarves were popular all over the world, the name of the town of Kawamata, where they were made, was hidden in the shadow of the port of Yokohama, from where they were exported. Today, though, Kawamata silk looks primed to build global fame in its own name.

A form of short-crust pasta, orzo is the Italian word for barley (from the Latin hordeum) and is shaped like a large grain or rice or barley.
As with any other pasta, it can be boiled and served on its own with a sauce and other toppings, or, because of its small size, it can be added to other recipes, such as soup, salads, pilaf, or to a casserole for baking. It is often found in soups such as minestrone. It can also be boiled and then fried, instead of rice, for a risotto-style dish.
Orzo is made by rolling the pasta dough into thick spaghetti-like lengths, flattening it slightly, then cutting it off short grain-like pieces.
The orzo pasta dough is usually made with semolina flour which in turn is made from the denser part of the wheat berry. This makes it somewhat harder and helps it to keep its shape while cooking so that it doesn't become floppy as with other pastas. It makes for a chewier result. Some manufacturers make whole wheat variations which are denser and nuttier in flavour and have all the benefits of whole grains, such as more protein a better fibre. Some manufactured varieties are also flavoured with tomato or spinach, and these will appear either pink or green in colour.
As an ingredient, orzo pasta soaks up flavour, easily absorbing the cooking liquid, which is why cooks use it to add bulk or interest to soups and broths. It is usually added dry then left to cook with the other ingredients when used in this way.


Science Fiction's Race Problem
March 28, 2014 | 2 books mentioned 1
How can science fiction writers invent aliens and entire planets but not include multifaceted characters of color in their fiction? At The Atlantic, Noah Berlatsky discusses the genre's equality problem and analyzes how race is viewed in everything from The Left Hand of Darkness to Do Androids Dream of Electric Sheep. "When that future unthinkingly reproduces current inequities, it seems like both a missed opportunity and a failure of imagination."
One comment:
 1. I read Left Hand of Darkness not too long ago. I don't remember ANYTHING about skin color, one way or the other. In fact, it's more common to NOT mention such a detail, especially in first person narrations. Hmm, let's see, what do I remember being mentioned about color in stories I've read? In Space Cops, there was a kid who was black–not by inheritance, but as if he was spray-painted, even on the inside of his mouth. A fan-fic work crossing Evangelion with Cthlulu Tech had four races: pure Terran, pure Nazzadi (black with red eyes), amlati (Terran/Nazzadi cross resulting in an "averaged" color), and sidoci (Terran/Nazzadi cross resulting in white-pigmented skin). I think there's a lot of stories where skin color was mentioned incidentally, but I don't remember it because it wasn't all that important to the story. And when you're playing with futuristic worlds and sub-species of human, (like the Neitcheansin Gene Roddenberry's Andromeda, which come on a rainbow of colors but are defined by their bone blades, immunity to chlorine gas, and ability to survive off foods and in environments that other varieties of humans can't) skin color often just isn't worth mentioning. If there's a sense of a particular contemporary race as having "taken over" the species, well, authors tend to write what they know, and they're going to look at a futuristic humanity through the lens of their own race. And how many SF authors are skin-color minorities? In fact, outside of specifically "colored" genres, what percentage of any authors are?

text: After a long drought for Pyramid Lake and the Truckee River, the Lake and river flows are finally up. The delta of the Truckee River at Pyramid Lake is a magnet for all kinds of birds and wildlife, and this year shows what can happen when flows approach more natural, unregulated conditions. Dams still control the flows of the Truckee River, but because of the large amount of precipitation and snowpack still to melt, this year resembles what likely occurred in the Truckee River most years before large-scale diversions and dam building. [The diversions and dams dropped Pyramid Lake 80 feet and reduced the Truckee River to a trickle at the Lake's delta by sending most of the water to Lahontan Valley Farms.] For the last hundred years, Pyramid Lake receives most of its water from the Truckee River in exceptional water years – like this one. We can only hope that this winter isn't another "one and done" event and next year brings plenty of precipitation and snow. Wildlife at Pyramid Lake would probably agree.

IMAP-Hi consists of two identical, single-pixel high energy ENA Imagers that measure H, He, and heavier ENAs from the outer heliosphere. Each IMAP-Hi Imager is very similar in design to the IBEX-Hi ENA Imager aboard the IBEX mission, but incorporates key modifications that enable substantially improved (1) spectral, spatial, and temporal resolution, (2) spectral range, and (3) collection power. The instrument also incorporates time-of-flight (TOF) for identification of ENA species. These performance enhancements, yielding ~25 times the collection power of IBEX-Hi, enable unprecedented, detailed studies of structure and evolution of source plasmas in the heliosphere-LISM interaction region.
The two IMAP-Hi imagers are mounted 90° (Hi90 imager) and 45° (Hi45 imager) antisunward relative to the spacecraft spin axis, respectively. Each spin, the Hi90 imager views the ecliptic poles, while the combined Hi90 and Hi45 imagers sample the ecliptic plane in four different locations. The Hi90 and Hi45 imagers also enable viewing the same low-latitude regions twice within 3 months to probe rapid ENA time variability. Additionally, the Hi45 imager has increased exposure of a factor of ×3.9 at the equator and nearly ×10 at 45° latitude, a band that contains ENA emission from the heliospheric nose and tail, as well as most of the Ribbon and Belt.
All schematics and numbers are preliminary as of the beginning of Phase A. Additional information about each instrument can be found in the Open Access IMAP Paper.

Maori men and women from different homelands
Engraving of Maori man and woman
"A New Zealand Warrior and his Wife", an engraving from the journal of Captain James Cook's visit on Endeavour (Pic: State Library of NSW)
The male and female ancestors of today's Maori people of New Zealand originated from different parts of the world, molecular biologists have said.
Their claims, made by Masters student Adele Whyte, the Tuapapa Putaiao Maori Fellow at Victoria University in Wellington, and her supervisor Professor Geoff Chambers, will be aired on ABC-TV's science program Catalyst tonight.
By comparing the DNA of people from Asia, across the Pacific Ocean and New Zealand, Whyte and Chambers have revealed a 'living genetic map' of ancient Maori migration routes.
The findings confirm archaeological evidence that the ancestors of today's Maori originally set out from mainland south-east Asia 6,000 years ago, hopped from island to island, starting with Taiwan, and arrived in New Zealand 800 to 1,000 years ago.
However the research also brings startlingly new evidence that as Maori ancestors migrated one group of islands to the next, men from Melanesian communities joined the boats. This changed the genetic mix, and lead to the differences observed in the genetic make-up of today's Maori men and women.
The research involved two separate genetic mapping processes. The Southeast Asian homeland was confirmed by Chambers' research into the frequency of two different genes that influence the body's reaction to alcohol. He found that while Asian people have both gene types, Maori and Pacific Islanders have inherited only one.
He looked back along the trail of migration to try and work out where the gene was lost. The indigenous people from Taiwan have both genes, but a lower frequency of one - the very gene that the Maori now lack.
"We think this one was lost at the first step of migration, when people left what is now Taiwan," Chambers told ABC Science Online.
The second mapping process involved Whyte's examination of sex-linked genetic markers, namely mitochondrial DNA in women, and Y-chromosomes in men. The research found that in addition to the alcohol genes, female Maori have other genetic markers which confirm their ancient Asian origin. To her surprise, however, the men have genetic markers that show a Melanesian ancestry.
"As a result of intermarriage along the migration trail, the signatures of the mitochondrial DNA from women have stayed more 'island south-east Asian', and the Y-chromosomes are more Melanesian," Whyte told ABC Science Online.
"We think both men and women set off together, and recruited local guides who were probably men. Women stayed with the south-east Asian populations, and Melanesian men were recruited along the way."
Genetic bottlenecks
Whyte also analysed the 'haplotypes' (groups of closely linked genes) carried on mitochondrial DNA, which is inherited only through the female line. Each population has a unique range of haplotypes. While Europeans have over 100 haplotypes in a particular region of DNA, studies so far have only found four different Maori haplotypes in the same region.
"The reason for this difference is what we call a genetic bottleneck. When people leave an island to go to the next island, obviously not everybody gets on the boat, so some of the genetic diversity is being lost," she said. "Some of the maternal lineages may not have got on the boat, so they're not carried on to the next place."
Whyte has now identified 10 haplotypes in New Zealand Maori. "From that we have worked out that 56 women came to New Zealand to create the diversity of today's population," she added.
Whyte said these findings were consistent with Maori legend.
"The story I was told when I was growing up is that there was a fleet of seven great waka (canoes) that came to New Zealand," she said. "Every tribe knows which waka their ancestors arrived in. My ancestors were in a waka called Takitimu."
"There might have been 20 people travelling in a canoe the size of a waka. Seven waka, that's about 140 people. And if, as we think, about half or 56 of these people happen to be women, it does seem to tie in."

A better quality of life
Nowadays, our life is dominated by noise and stress. The primary source of noise pollution is road traffic noise. The experts of FUCHS can contribute to noise reduction.
Our noise protection walls are made of precast concrete parts. They consist of one concrete supporting layer and one facing layer made of single-grain concrete. The single-grain concrete layer which is directed to traffic absorbs noise. The concrete wall works as a shield. It protects the side away from traffic from traffic noise. Highly absorbent precast concrete parts even on both sides can be produced if the location requires it.
Convincing in every kind of way
The highly absorbent noise protection wall by FUCHS Fertigteilwerke offers various scopes for design. The walls can be adapted to their environment by forms or coloring and even become an eye-catcher due to special design elements or patterns.

The Analysis of Slice-Induced Factors in Golf Swing Using a 3D Motion Capture System
In golf, it is crucial that unintended shots, such as slices, be minimized. However, it has proven rather difficult to improve golf performance via investigations of the causes of slicing, as this particular phenomenon is induced by a cooperative effect by each segment of the body, rather than by a single postural anomaly. Thus, the objective of this study was to isolate and characterize the factors causing slicing, and to present possibilities for the improvement of golf performance via the minimization of the number of slices executed, using a three dimensional motion capture system, combined with multiple regression analysis, artificial neural network, and fuzzy logic techniques. This study obtained some interesting results, such as the following: (1) We isolated 9 slice-inducing factors, using a stepwise method. (2) Our artificial neural network (ANN) accurately separated'slice' from 'normal' shots (classification rate: 100%). (3)We could present the possibility of reducing the number of slice using the fuzzy logic. We expect that our data might be eventually used to improve golf performance.

Sinusoidal oscillators are known to be realized using dynamical systems of second-order or higher. Here we derive the Barhkausen condition for a linear noninteger-order (fractional-order) dynamical system to oscillate. We show that the oscillation condition and oscillation frequency of some famous integer-order sinusoidal oscillators can be obtained as special cases from general equations governing their fractional-order counterparts. Examples including fractional-order Wien oscillators, Colpitts oscillator, phase-shift oscillator and LC tank resonator are given supported by numerical and PSpice simulations. © 2008 IEEE.

Would you take offence at being called a West Brit? The term has a muddled history
Sinn Féin's Micheal Mac Donncha caused controversy when he made the remarks earlier this week.
EARLIER THIS WEEK there was controversy when Sinn Féin councillor Micheál Mac Donncha used the term 'West Brit' to describe the people who run Irish rugby.
Speaking to TheJournal.ie, Mac Donncha defended the remark, saying:
"It was a Facebook comment, it wasn't a public statement. I think I reflects the attitude of a lot of people who regard the fact that there is no playing of the national anthem as being an anti-national attitude."

He was criticised for his comments by Fine Gael councillor Neale Richmond, who called them "petty sniping".
Later, the Fine Gael senator Jim D'Arcy said the American equivalent of the term would be to call someone an 'Uncle Tom'.
So where did the term come from? And how offensive is it?
How did the term come about?
The origin of the term can be traced back to its use in the British House of Commons by Irish nationalist leader Daniel O'Connell, when he was proposing that it would be beneficial for Ireland to become a sort of 'West Briton'.
The term later came to prominence through its use in nationalist magazine 'The Leader', with journalist D.P. Moran using it to described individuals he did not view as sufficiently Irish.
By the early part of the last century it had been firmly cemented as a term of derision, with the Gaelic League (below) using it to promote Irish identity, in opposition to pandering to the United Kingdom.

How offensive is it?
While it may have a muddled history, the term is now used only as an insult.
This most recent incident is not the first time that a Sinn Féin politician has found themselves in the spotlight over its use.
In 2011 Martin McGuinness used the term to criticise "elements" of the Dublin media during his presidential run.
Following this, it was noted by Miriam Lord in the Irish Times that it would be difficult for McGuinness to represent all of the people of Ireland if that was his attitude.
When asked about his comments McGuinness distanced himself from them, describing it as "an off-the-cuff remark".
In 2011, Anglican priest and journalist Patrick Comerford described the term as "racist and pejorative" and that its use is unacceptable in a pluralist democracy.

A 100 percent sustainable, self-build, co-housing scheme
I am hoping to solve the climate and housing problems on the Isles of Scilly, including the second home ownership issue which leaves many residents struggling to own homes because of the increased house prices. This led me to develop key 'Zero Waste' principles. Considering the Scilly problems and the three pillars of holistic sustainability (community, economy and ecology) I am proposing an Ikeatype/ wiki-house instruction booklet to self-build a 100 percent sustainable self-build co-housing scheme. This includes improving on existing sustainability standards.
I want to go beyond the Passivhaus certification and address embodied carbon and wellbeing.
I also want to push the co-housing principles to the max. Reconsidering the common house (a key element of a co-housing scheme) and adding the additional element of a zero waste, resident – run recycling centre, with workshop and shop to initiate a circular economywaste to resource system on the island.
Illustrations of the 3 key drivers of the scheme: Materials for their lifespan, Holisitc Sustainability approach and A Cyclical House System.
1. Materials used for their lifespan
2. Holistic sustainability
3. A cyclical house system
The overall site plan displaying the landscaping of wild and more defined allotments acting as a buffer zone between front door and communal paths.
A contrast between the structured "growth gardens" and "free,wild gardens" shows a buffer between public and private. Each residence and the commonhouse/ recycling centre have their own 2 metre buffer perimeter.
Rendered View of the inbetween spaces, that the wild landscape inhabits and the built form shares.
A wild landscape embraces the houses and common house to re-introduce biodiversity and promote a sustainable way of living to the max.
The house model broken down as an exploded axonometric to show how it is ticking the sustainability agenda set out for the scheme.
To achieve 100 percent sustainability the house must be easily built, affordable and achieve (at minimum) a PassivHaus certification.

|Ada 95 Quality and Style Guide||Chapter 8|
Reusability is the extent to which code can be used in different applications with minimal change. As code is reused in a new application, that new application partially inherits the attributes of that code. If the code is maintainable, the application is more maintainable. If it is portable, then the application is more portable. So this chapter's guidelines are most useful when all of the other guidelines in this book are also applied.
Several guidelines are directed at the issue of maintainability. Maintainable code is easy to change to meet new or changing requirements. Maintainability plays a special role in reuse. When attempts are made to reuse code, it is often necessary to change it to suit the new application. If the code cannot be changed easily, it is less likely to be reused.
There are many issues involved in software reuse: whether to reuse parts, how to store and retrieve reusable parts in a library, how to certify parts, how to maximize the economic value of reuse, how to provide incentives to engineers and entire companies to reuse parts rather than reinvent them, and so on. This chapter ignores these managerial, economic, and logistic issues to focus on the single technical issue of how to write software parts in Ada to increase reuse potential. The other issues are just as important but are outside of the scope of this book.
One of the design goals of Ada was to facilitate the creation and use of reusable parts to improve productivity. To this end, Ada provides features to develop reusable parts and to adapt them once they are available. Packages, visibility control, and separate compilation support modularity and information hiding (see guidelines in Sections 4.1, 4.2, 5.3, and 5.7). This allows the separation of application-specific parts of the code, maximizes the general purpose parts suitable for reuse, and allows the isolation of design decisions within modules, facilitating change. The Ada type system supports localization of data definitions so that consistent changes are easy to make. The Ada inheritance features support type extension so that data definitions and interfaces may be customized for an application. Generic units directly support the development of general purpose, adaptable code that can be instantiated to perform specific functions. The Ada 95 improvements for object-oriented techniques and abstraction support all of the above goals. Using these features carefully and in conformance to the guidelines in this book, produces code that is more likely to be reusable.
Reusable code is developed in many ways. Code may be scavenged from a previous project. A reusable library of code may be developed from scratch for a particularly well-understood domain, such as a math library. Reusable code may be developed as an intentional byproduct of a specific application. Reusable code may be developed a certain way because a design method requires it. These guidelines are intended to apply in all of these situations.
The experienced programmer recognizes that software reuse is much more a requirements and design issue than a coding issue. The guidelines in this section are intended to work within an overall method for developing reusable code. This section will not deal with artifacts of design, testing, etc. Some research into reuse issues related specifically to the Ada language can be found in AIRMICS (1990), Edwards (1990), and Wheeler (1992).
Regardless of development method, experience indicates that reusable code has certain characteristics, and this chapter makes the following assumptions:
In addition to these criteria, a reusable part must be easier to reuse than to reinvent, must be efficient, and must be portable. If it takes more effort to reuse a part than to create one from scratch or if the reused part is simply not efficient enough, reuse does not occur as readily. For guidelines on portability, see Chapter 7.
- Reusable parts must be understandable. A reusable part should be a model of clarity. The requirements for commenting reusable parts are even more stringent than those for parts specific to a particular application.
- Reusable parts must be of the highest possible quality. They must be correct, reliable, and robust. An error or weakness in a reusable part may have far-reaching consequences, and it is important that other programmers can have a high degree of confidence in any parts offered for reuse.
- Reusable parts must be adaptable. To maximize its reuse potential, a reusable part must be able to adapt to the needs of a wide variety of users.
- Reusable parts should be independent. It should be possible to reuse a single part without also adopting many other parts that are apparently unrelated.
This chapter should not be read in isolation. In many respects, a well-written, reusable component is simply an extreme example of a well-written component. All of the guidelines in the previous chapters and in Chapter 9 apply to reusable components as well as components specific to a single application. As experience increases with the 1995 revision to the Ada standard, new guidelines may emerge while others may change. The guidelines listed here apply specifically to reusable components.
Guidelines in this chapter are frequently worded "consider..." because hard and fast rules cannot apply in all situations. The specific choice you can make in a given situation involves design tradeoffs. The rationale for these guidelines is intended to give you insight into some of these tradeoffs.

K'inich Janaab' Pakal
From Wikipedia, the free encyclopedia
Jump to: navigation, search
K'inich Janaab' Pakal
Ajaw of Palenque
Pacal the Great
Reign July, 615 – August, 683 CE
Full name K'inich Janaab' Pakal
Born - March 603
Died - August 683 age 80
Buried Temple of the Inscriptions, Palenque
Predecessor Sak K'uk'
Successor K'inich Kan B'alam II
Issue K'inich Kan B'alam II
K'inich K'an Joy Chitam II
Father K'an Mo' Hix
Mother Sak K'uk'
K'inich Janaab' Pakal[pronunciation?] (March 603 – August 683)[1] was ruler of the Maya polity of Palenque in the Late Classic period of pre-Columbian Mesoamerican chronology. During a long reign of some 68 years Pakal was responsible for the construction or extension of some of Palenque's most notable surviving inscriptions and monumental architecture.
Before his name was securely deciphered from extant Maya inscriptions, this ruler had been known by an assortment of nicknames and approximations, including Pakal[pronunciation?] (or Pacal), "Sun Shield", "8 Ahau", and (familiarly) as Pacal the Great. The word pakal means "shield" in the Maya language.
In modern sources his name is also sometimes appended with a regnal number,[2] to distinguish him from other Janaab' Pakals that either preceded or followed him in the dynastic lineage of Palenque. Confusingly, he has at times been referred to as either "Pakal I" or "Pakal II". Reference to him as Pakal II alludes to his maternal grandfather (who died in 612) also being named Janaab' Pakal. However, although his grandfather was a personage of ajaw ranking, he does not himself appear to have been a king. When instead the name Pakal I is used, this serves to distinguish him from two later known successors to the Palenque rulership, Upakal K'inich Janaab' Pakal (ruled c. 742, aka "[K'inich Janaab'] Pakal II") and Wak Kimi Janaab' Pakal (aka [Janaab'] Pakal III), the last-known Palenque ruler, who acceded in 799.
Pakal ascended the throne at age 12 in July, 615 - Long Count 5 lamat 1 mol,[3] and lived to the age of 80. He expanded Palenque's power in the western part of the Maya states and initiated a building program at his capital that produced some of Maya civilization's finest art and architecture. He was preceded as ruler of Palenque by his mother, Lady Sak K'uk'. As the Palenque dynasty seems to have had Queens only when there was no eligible male heir, Sak K'uk' transferred rulership to her son upon his official maturity.
After his death, Pakal was succeeded by his son K'inich Kan B'alam II. A younger son, K'inich K'an Joy Chitam II, succeeded his brother K'inich Kan B'alam II. After his death, Pakal was deified and was said to communicate with his descendants; he was buried within the Temple of Inscriptions. Though Palenque had been examined by archaeologists before, the secret to opening his tomb — closed off by a stone slab with stone plugs in the holes, which had until then escaped the attention of archaeologists—was discovered by Mexican archaeologist Alberto Ruz Lhuillier in 1948. It took four years to clear the rubble from the stairway leading down to Pakal's tomb, but was finally uncovered in 1952.[4] His skeletal remains were still lying in his coffin, wearing a jade mask and bead necklaces, surrounded by sculptures and stucco reliefs depicting the ruler's transition to divinity and figures from Maya mythology. Traces of pigment show that these were once colorfully painted, common of much Maya sculpture at the time.[5]
Whether the bones in the tomb are really those of Pakal is under debate because analysis of the wear on the skeleton's teeth places the age of the owner at death as 40 years younger than Pakal would have been at his death. Epigraphers insist that the inscriptions on the tomb indicate that it is indeed K'inich Janaab' Pakal entombed within, and that he died at the age of 80 after ruling for around 70 years. Some contest that the glyphs refer to two people with the same name or that an unusual method for recording time was used, but other experts in the field say that allowing for such possibilities would go against everything else that is known about the Maya calendar and records of events. The most commonly accepted explanation for the irregularity is that Pakal, being an aristocrat, had access to softer, less abrasive food than the average person so that his teeth naturally acquired less wear.[6] Despite the controversy, it remains one of the most spectacular finds of Maya archeology. A replica of his tomb is found at the National Museum of Anthropology and History in Mexico City.
Carved lid of the tomb of K'inich Janaab' Pakal in the Temple of the Inscriptions.
Iconography of Pakal's sarcophagus lid[edit]
The large carved stone sarcophagus lid in the Temple of Inscriptions is a unique piece of Classic Maya art. Iconographically, it is closely related to the large wall panels of the temples of the Cross and the Foliated Cross centered on world trees. Around the edges of the lid is a band with cosmological signs, including those for sun, moon, and star, as well as the heads of six named noblemen of varying rank.[7] The central image is that of a cruciform world tree. Beneath Pakal is one of the heads of a celestial two-headed serpent viewed frontally. Both the king and the serpent head on which he seems to rest are framed by the open jaws of a funerary serpent, a common iconographic device for signalling entrance into, or residence in, the realm(s) of the dead. The king himself wears the attributes of the Tonsured maize god - in particular a turtle ornament on the breast - and is shown in a peculiar posture that may denote rebirth.[8] Interpretation of the lid has raised controversy. Linda Schele saw Pakal falling down the Milky Way into the southern horizon,[9] a view that would not appear to have found general acceptance among scholars.
Pakal and his sarcophagus in popular culture[edit]
Erich von Däniken's "Maya Astronaut"[edit]
Pakal's tomb has been the focus of attention of some "ancient astronaut" enthusiasts since its appearance in Erich von Däniken's 1968 best seller, Chariots of the Gods?. Von Däniken reproduced a drawing of the sarcophagus lid, incorrectly labeling it as being from "Copan" and comparing Pacal's pose[10] to that of Project Mercury astronauts in the 1960s, interpreting drawings underneath him as rockets, and offering it as evidence of a supposed extraterrestrial influence on the ancient Maya.
Von Däniken's claim is not considered a credible interpretation by any professional Mayanist. For example Ian Graham responded, "Well I certainly don't see any need to regard him as a space man. I don't see any oxygen tubes. I see a very characteristically drawn Maya face."[citation needed]
José Argüelles' "Pacal Votan"[edit]
Another example of this carving's manifestation in pseudoarchaeology is the identification by José Argüelles of "Pacal Votan" as an incarnation named "Valum Votan," who will act as a "closer of the cycle" in 2012 (an event that is also significant on Argüelles' "13 Moon" calendar). Daniel Pinchbeck, in his book 2012: The Return of Quetzalquatl (2006), also uses the name "Votan" in reference to Pakal. However, this name is not used for Pakal by Mayanist researchers such as academic archaeologists, epigraphers, and iconographers. Argüelles claims a connection between Pakal and the semi-historical Toltec figure Topiltzin Ce Acatl Quetzalcoatl, but this is not supported by archaeological or epigraphic evidence. New Age interpretations of Pakal's tomb are a cornerstone of contemporary Mayanism.

The The Effect of the Kahoot Quiz on the Student's Results in the Exam
Students taking low-stake quizzes in a gamified environment shows improvement on their studies, thus has the potential to be an effective part in an improved learning experience. Previous researches show that implementing gamification into the educational system has positive outcome on the student's engagement, motivation and the overall experience of learning. In this study is a field experiment, where quizzes were created with the Kahoot application, to bring action and visual triggers into the classroom. The aim of this paper to measure the long-term learning effect of the Kahoot quiz in the exams. Several of the quiz questions during the class were purposefully blended into the exam's question bank as a multiple choice or a true or false question. In this research 200 bachelor students participated in a 14-week long elective course. The data was collected weekly from the Kahoot quizzes and from the two mandatory exams. All the results from the Kahoot quiz and the exams provided the base of the analysis. Furthermore, the exam results were analyzed based on number of Kahoot quizzes they took part, a comparison of the results of each question based. The results show that students who took part in more Kahoot quizzes tend to reach higher exam mark. Moreover, they marked more correct answers and less incorrect ones. As a conclusion, using some level of game-based learning has a positive effect on the student's results and perception of learning.

Evaluating long term outcomes for students with learning disabilities : does age of first services matter?
MetadataShow full item record
Within the last few decades there has been a push in the field of learning disabilities to identify students who have or who are at risk for learning disabilities as early as possible. Little to no research has been conducted on the long-term effects of age of first service provision for students with learning disabilities, however. Using multiple regression, this study will analyze data from the National Longitudinal Transition Study-2 (NLTS-2) to investigate the potential effects of age of first service provision on high school educational achievement and educational attainment in order to better understand the longer-term effects of the age of identification and age of intervention for students with learning disabilities.


Getting Started with Service with a Subject in Angular
A powerful technique in Angular is the built in integration with RxJS. Making use of reactive programming (ie. RxJS) can remove a lot of code from your Angular application. This is an indictor that reactive programming takes care of a lot of the logic you would otherwise have to come up with and test yourself.
There are simple steps you can take to get started with writing reactive Angular applications. You can then use the understanding and confidence you get from the simple steps to start using reactive programming in other, more complicated cases.
Simple Service with a Subject
The following code is a simple Angular service with a subject.
// name.service.ts
import { Injectable } from '_USER_/core';
import { BehaviorSubject, Observable } from 'rxjs';
 providedIn: 'root'
export class NameService {
 private mName$ = new BehaviorSubject(null);
 name$(): Observable {
 return this.mName$;
 constructor(private httpClient: HttpClient) { }
 loadName() {
 this.httpClient.get('name URL')
 .subscribe(name => this.mName$.next(name));
There are 3 pieces to the subject that come together to trigger getting the name from the API and passing on the retrieved name.
API Call
The entry point for a user of the service is the loadName function on line 18. It triggers the HTTP call to the API and passes on the retrieved name to mName$ in the subscribe call on line 20.
Storing the Retrieved Name
The mName$ member variable on line 10 of the service is used as private intermediate storage of the name retrieved from the API in the service. mName$ is tightly linked to the name$ function which is used to control access to the intermediate storage.
Passing on the Retrieved Name
The name$ function of the service is used to pass on the name retrieved from the API on line 12. Hiding the private intermediate storage mName$ behind the name$ function allows control over how the name is distributed throughout the Angular application.
The next step is to show the name in a component.
Reactive Component
Once the name has been retrieved from the API, the next step is to show it in a component.
Component Typescript Code
The following is the typescript code for the component.
// name.component.ts
import { Component, OnInit } from '_USER_/core';
import { NameService } from './name.service';
 selector: 'app-name',
 templateUrl: './name.component.html',
 styleUrls: ['./name.component.css']
export class NameComponent implements OnInit {
 constructor(public nameService: NameService) { }
 ngOnInit() {
There is hardly any code in the component that is not part of the required Angular component code. The only line that has been added is line 15 which instructs the service to load the name along with importing the service on line 4 and injecting it into the component on line 12.
Component Template
The following is the HTML template associated with the component.
 {{ name }}
In the template the name$ function of the service is passed to the async pipe on line 2. The values emitted by the name$ observable are renamed to the name variable and then displayed on line 3.
That concludes the simple example for making use of a subject with a service. There are some additions to consider depending on the use case. For example, you may want to introduce error handling in the subject. You may also want to write tests for the service and the component.

Nahdet Masr – Egypt's Awakening
Nahdet Masr statue
Nahdet Masr and Muslim Brotherhood supporters. Nov 30,2012
Nahdet Masr or Egypt's Awakening, the rose granite monumental statue that faces University Bridge in Giza, was born out of another era. Mahmoud Mukhtar (_PHONE_) sculptured Nahdet Masr to symbolize Egyptian national aspirations during the struggle for independence from British occupation that began in 1882. Mahmoud Mukhtar lived during tumultuous times not unlike what we are experiencing today. On the heels of World War I and in the wake of Egypt's 1919 Revolution, his response to the social and political changes of the day was in his art. By using his sculptures as vehicles to express the nation's awakening and national identity, he revived Egypt's old glory and raised Egyptian pride drawn from the antiquities of ancient Egypt.
4165801The Nahdet Masr statue is of a Sphinx and a peasant woman both representing Egypt. With her left hand she begins to unveil her face signifying Egypt's revival while her right arm stretches over the Sphinx, which recalls the greatness of Egypt's history. The sculptures pyramidal shape signifies resolve and confidence in the future. The Sphinx rises on it front paws to denote strength to intimidate its foes and enthusiasm for the future. The sculpture was fist unveiled in 1928 in front of the train station in Bab al -Hadid. In 1955 it was transferred to Giza and erected facing east so that each day as the sun strikes the monument as if to awaken Egypt.
Could Mahmoud Mukhtar be turning over in his grave as the Muslim Brotherhood rally around Nahdet Masr? Can all Egyptians, no matter their ideology, look to Nahdet Masr as a representation of expressions of national aspirations and identity? Or is this exactly what Mukhtar had in mind when he unveiled his sculpture to the world? The answer might be found in Mukhtar's own words, he said, "that he wished to create a statue that combined all the dreams of Egypt and its civilization, blending the glorious past with the nation's future aspirations. This is how the idea of Nahdet Masr was born." ("Tale of a statue: Nahdet Masr", Al Ahram Weekly, May 24-30, 2012).
Egypt has been a crossroad for every major civilization in the world and remnants of these ancient civilizations still remain, real treasures of world heritage. These relics are touchstones to past and give us insight to why it is in human nature to be remembered and glorified. From ancient Egyptians use of the pyramids and obelisks that symbolized timelessness and memorialization to the Mamluk's tomb complexes to present-day street statues, the use of monuments, sculptures, and statues have always represents authority, glory and identity of societies and civilizations.
Do people really care about these symbols? Judging from the defacing graffiti and the statues, on the demonstrator's routes, used as a climbing frame for a higher vantage point, the symbolism and significance of the statues that commemorate outstanding contributions of Egyptian leaders as well as representing national identity seemingly holds little importance in the public's consciousness. At best, the statues are invisible, (which may be what protects them from destruction).
Is Egypt experiencing a democratic awakening or falling into dismal chaos? It is certain that the ousted government of Hosny Mubarak had a 30 year window to position Egypt as a developed country. It is noteworthy to remember that under Mubarak, Egyptians did live in peace for 3 decades and the country's infrastructure did improve i.e. metro system, road and bridge development. There was progress in many fields and in some sectors the economy was doing well. However, Mubarak's government also turned a blind eye to the growing demand for political diversity and ignored serious poverty, population and unemployment issues, combined with the Internet, Twitter, Facebook – all components that level the playing field – and the overwhelming pressure of the underrepresented, Egypt's so-called revolution began to play itself out again on January 25, 2011, but can it be labeled an 'awakening' or 'revival'? The road will be long to answer that question.

5 tricks to eliminate render blocking resources

5 Tricks to Eliminate Render Blocking Resources
Render blocking resources are static files, such as fonts, HTML, CSS, and JavaScript files, that are vital to the process of rendering a web page. When the browser encounters a render blocking resource, it stops downloading the rest of the resources until these critical files are processed. In the meantime, the entire rendering process is put on hold. On the other hand, non-render blocking resources don't postpone the rendering of the page. The browser can safely download them in the background after the initial page render.
However, not all resources that the browser deems render blocking are essential for the first paint; it all depends on the individual characteristics of the page. There are best practices you can use to turn these noncritical render blocking resources into non-render blocking ones. Besides, you can also decrease the number and/or size of render blocking resources that are still critical and can't be eliminated.
Why eliminate render blocking resources?
If you reduce the number of render blocking resources, you can shorten the critical rendering path and reduce page load times, thus improving the user experience and search engine optimization.
There are three ways to reduce the number and impact of render blocking resources:
 1. Make them non-render blocking resources by deferring their download
 2. Decrease the total number of render blocking resources using techniques such as bundling (this also means fewer HTTP requests)
 3. Reduce the size of a resource via minification so that the page has fewer bytes to load
Types of render blocking resources
As a rule of thumb, the browser treats everything it finds in the section of an HTML page as render blocking. This includes:
 - CSS stylesheets
 - JavaScript files added in the section
 - Fonts added from either CDN or a local server
 - HTML imports (even though HTML imports are now obsolete, you might still encounter them on legacy pages)
Images, media files, and tags placed at the bottom of the <body> section are treated as non-render blocking resources.
Now let's zoom in on five strategies to eliminate or reduce the number and impact of render blocking resources.
1. Don't add CSS with the _USER_ rule
You can add CSS to a page using either:
 - The <link rel="stylesheet"> tag that you need to add to your HTML file
 - The _USER_ rule that you need to add to your CSS file
Even though the _USER_ rule keeps your HTML file cleaner and allows you to keep all your CSS dependencies in the same place, it's not the best choice performance-wise. The _USER_ rule lets you import CSS from other stylesheets, but this causes the browser to process your CSS file more slowly because it also has to download the imported files. Until this takes place, the rendering process will be blocked.
If you want to add more than one CSS file to your page, you can either use the <link> tag or concatenate the files using a minification and/or bundling tool.
We made a custom demo for.
No really. Click here to check it out.
You need to add the <link> element to the <head> section of the HTML page in the following way:
2. Use the media attribute for conditional CSS
By default, the browser treats all CSS files as render blocking resources. However, if you add the media attribute to the <link> tag, you can indicate the presence of a conditional CSS file to the browser.
Conditional CSS only applies under certain conditions, such as below or above a given viewport size or on a print page. With the media attribute, you can define a specific media condition for a CSS file. You can use any value that you would use for a media query in a CSS file. For example:
<link href="large.css" rel="stylesheet" media="screen and (min-width: 1500px)">
Even though these files are still download on all devices, they become non-render blocking resources if the condition evaluates as false. However, they will still be render blocking if the condition evaluates as true.
For instance, the mobile.css stylesheet in the above example will be render blocking on mobile devices with a maximum viewport width of 600px and non-render blocking on viewports larger than 600px.
If you have an existing CSS file with one or more media queries, you can extract all _USER_ rules and save them as separate files using this PostCSS plugin. This performance optimization technique is also called code splitting. Although code splitting is usually mentioned in conjunction with JavaScript, you can also split larger CSS files and load each file only when needed to shorten the critical rendering path and decrease initial page load times.
3. Use the defer and async attributes to eliminate render blocking JavaScript
JavaScript files added to the <head> section of the document are treated as render blocking resources by default.
You can remove them from the critical rendering path by placing the <script> tags right before the closing </body> tag instead of the <head> section. In this case, they only begin to download after the entire HTML has been downloaded. However, because the download of these scripts starts later, elements loaded by them, such as ads, animations, or dynamic functionalities, might load later than the rest of the frontend — especially if it's a longer script. This can result in noticeable delays and lagging UIs on slower connections, which is bad for the user experience.
The defer and async attributes of the <script> tag offer a solution to this problem. Both are Boolean attributes which means that if you add them, they will fire without any further configuration. They also make scripts added to the <head> section of an HTML document non-render blocking, but in a different way — deferred scripts respect the document order while asynchronous scripts are independent of the DOM.
The defer attribute instructs the browser to download the script in the background so it won't block the rendering of the page. The deferred script executes once the DOM is ready but before the DOMContentLoaded event fires.
<script src="script01.js" defer>
Deferred scripts follow the document order, just like nondeferred, default scripts. For example, in the above example, script01.js will be executed first, irrespective of which script loads first. You can't add defer to inline scripts; it only works with external scripts that specify the script's location using the src attribute.
On the other hand, the async attribute informs the browser that a script is completely independent of the page. It will download in the background as a non-render blocking resource, just like deferred scripts. However, unlike deferred scripts, async scripts don't follow the document order, so they will execute whenever they finish downloading — which can happen at any time.
For instance, in the below example, we can't be sure which script will run first; it solely depends on which downloads faster (usually the smaller one). Remember, async scripts are independent of both the document and each other, so the document order won't impact them in any way.
The defer attribute is recommended for scripts that need the DOM, but you want to begin to download them before the document loads, without making them a render blocking resource. You should also use defer rather than async if the document order is important — for instance, when consecutive scripts depend on each other.
The async attribute is recommended for independent third-party scripts, such as ads, trackers, and analytics scripts. For example, Google Analytics recommends adding the async attribute to support asynchronous loading in modern browsers.
4. Minify and bundle CSS and JavaScript
In addition to removing nonessential CSS and JavaScript from the critical rendering path, you can also minify and bundle both render blocking and non-render blocking resources.
For instance, you can create bundles for files that use the same loading rules and minify each bundle separately. Since minified files are lighter and bundles mean fewer files in the critical rendering path, initial page rendering will finish sooner. Plus, it will also take less time to download non-render blocking resources in the background.
There are numerous tools available to help you perform minification and bundling according to best practices, including Minify, CSS Minifier, Minify Code, and PostCSS. Build tools such as webpack, Parcel, and Rollup come with built-in minification, bundling, and code splitting functionalities that enable you to quickly reduce the number of render blocking resources.
5. Load custom fonts locally
Since custom fonts are called from the section of the document, they are also render blocking resources. For instance:

You can reduce the impact of custom fonts on initial page rendering by adding them locally rather than pulling them from a content delivery network such as Google CDN. Font providers tend to add multiple _USER_-face rules, many of which you won't need.
For example, Google Fonts add _USER_-face rules for all the character sets a typeface comes with, such as Latin, Cyrillic, Chinese, Vietnamese, and others. Let's say, for instance, that the online CSS file you add with the tag includes _USER_-face rules for seven different character sets, but you only want to use one (e.g., Latin). However, Google Fonts don't download the font files for all the character sets; they just add many redundant _USER_-face rules to the CSS file.
If you add fonts

A new article by Logrus IT's CEO, Leonid Glazychev, has been published in Linguistics and Literature Studies, a professional journal issued by Horizon Research Publishing Corporation. Below is the abstract and the download link.
The article introduces the first hybrid language quality assurance (LQA) methodology for translated texts, the Quality Triangle. This methodology was developed to assess original translated materials, with no available reference translations. It combines holistic and analytical approaches and provides the most flexible solution for a wide variety of applications and subject areas. Special attention is paid to the proposed approach detailing how holistic quality factors can be taken into account given the challenge they represent: these factors need to be assessed, but are at the same time not completely objective by definition. The resulting Quality Triangle methodology provides a reliable model for incorporating semi-objective, holistic factors into quality assurance metrics and can serve as the foundation for building models applicable in real production processes and serving a multitude of purposes.

Litigation and Arbitration Venue Provisions in Construction Contracts: When and How They Work
Venue and choice-of-law provisions are fairly standard in construction contacts, but can be overlooked due to their location within a contract. When drafted effectively, these provisions can help limit uncertainty about where and how disputes will be resolved. In this article for Construction Executive, Kenneth E. Rubinstein and Eric Penley examine best practices for understanding the implications of these provisions and how they can be enforced.

Multi-Scale 3D Convolution Network for Video Based Person Re-Identification
This paper proposes a two-stream convolution network to extract spatial and temporal cues for video based person ReIdentification (ReID). A temporal stream in this network is constructed by inserting several Multi-scale 3D (M3D) convolution layers into a 2D CNN network. The resulting M3D convolution network introduces a fraction of parameters into the 2D CNN, but gains the ability of multi-scale temporal feature learning. With this compact architecture, M3D convolution network is also more efficient and easier to optimize than existing 3D convolution networks. The temporal stream further involves Residual Attention Layers (RAL) to refine the temporal features. By jointly learning spatial-temporal attention masks in a residual manner, RAL identifies the discriminative spatial regions and temporal cues. The other stream in our network is implemented with a 2D CNN for spatial feature extraction. The spatial and temporal features from two streams are finally fused for the video based person ReID. Evaluations on three widely used benchmarks datasets, i.e.,MARS, PRID2011, and iLIDS-VID demonstrate the substantial advantages of our method over existing 3D convolution networks and state-of-art methods.


Florida Monkeys Threaten Residents With Herpes
 September 14, 2013
 Amanda Crum
A large group of Rhesus monkeys from a small island near Silver River are now posing a health threat to Floridians, wildlife experts say.
The monkeys–which were first brought to the area by tour guide Colonel Tooey in the 1930's–have had a population boom over the years and eventually learned to swim, and now hundreds of them are infected with Herpes B and are moving towards Jacksonville. Officials say the virus is rarely transmitted to humans, but it is possible, and it can be deadly.
The virus is caused by Macacine herpesvirus 1, according to the Center for Disease Control.
The virus is commonly found among macaque monkeys, including rhesus macaques, pig-tailed macaques, and cynomolgus monkeys (also called crab-eating or long-tailed macaques), any of which can harbor latent B virus infection and appear to be natural hosts for the virus. Monkeys infected with B virus usually have no or only mild symptoms. In addition, rabbits, guinea pigs, and mice can be experimentally infected with B virus. Infection with B virus is extremely rare in humans; however, when it does occur, the infection can result in severe neurologic impairment or fatal encephalomyelitis if the patient was not treated soon after exposure.
Local residents are being urged not to approach the animals, no matter how friendly they may seem.

What's an operating procedure?
Operating procedures are written instructions that list the steps for a given task and describe how the steps are to be performed. Operating procedures are normally used to control activities that are routinely and non-routinely performed by operators.
Operating procedures are required to safely start-up, operate, and shut down processes, including emergency shutdown. Operating procedures complement safe work and asset integrity procedures.
Without written procedures, a facility may not have the intended procedures and methods used by each operator or consistently execute a particular task in an intended manner. Procedures should be updated and reviewed periodically to ensure that they remain valid.
Some of the examples of processes which require operating procedures:
 - Initial start-up
 - Normal operations
 - Temporary operations
 - Emergency shutdown
 - Emergency operations
 - Normal shutdown
 - Start-up after a turnaround or emergency shutdown
Operating procedures help to ensure that everyone understands their roles/responsibilities in the task and maximizes the efficiency of work processes.
Here is an example of a Troubleshooting Flowchart
Procedures should be written in a universal language whereby everyone will be able to understand. Not only that, but procedures should also have sufficient details written so that a qualified worker can understand consistently and successfully perform the task.
