Experimental Analysis on Use of Polypropylene in Concrete

Polypropylene may be a thermoplastic polymer utilized as a neighborhood of wide assortment of uses including bundling, materials (e.g., ropes, warm clothing and covers). Polymer cement may be a piece of gathering of cements that utilizes polymers to supplement bond as a canopy. Impregnated solid, polymer cement, and Polymer-Portland-bond concrete are the sorts incorporate polymers. To realize maximum strength of concrete by using optimum weight of polypropylene fibers is the aim of the study. Fiber ferroconcrete is employed during a sort of engineering applications due to its satisfactory and outstanding performance within the industry and construction field. Polypropylene fiber in concrete mix design is used for multiple purposes that include rigid pavement, self- compacting concrete and other applications. 40 cylinders of polypropylene concrete were casted and tested for 7 and 28 days’ strength for both compressive and split lastingness. It was concluded that the many improvement was observed in ultimate compressive strength after 7 and 28 days. The optimum percentage of Polypropylene fiber was obtained to be 5 percent of cement by volume. The addition of bit of polypropylene improved the mechanical properties of concrete.

Properties of Surface Heating Textile for Functional Warm Clothing Based on a Composite Heating Element with a Positive Temperature Coefficient

A high-stretch positive temperature coefficient (PTC) surface heating textile (PTC-SHT) was fabricated using a composite of PTC powder and multiwall carbon nanotubes (MWCNTs). The PTC-SHT (heating area = 100 × 100 mm2) was produced by screen-printing the PTC-MWCNT composite paste onto a high-stretch textile with embroidered electrodes. Overall, the temperature increased to 56.1 °C with a power consumption of 5 W over 7 min. Subsequently, the surface temperature of the PTC-SHT remained constant despite the continued decrease in power consumption. This indicated that heating was accompanied by an increase in resistance of the PTC-SHT, which is typical of this process—i.e., heating to a constant temperature under a constant voltage over an extended period of time. In addition, 4.63 W power was required to heat the PTC-SHT surface from an external temperature of 5 to 45 °C in 10 min, after which stable low-temperature heat generation behavior was observed at a constant temperature of 50 °C, which was maintained over 40 min. In contrast, negative temperature coefficient (NTC) behavior has been observed in an NTC-SHT consisting of only MWCNTs, where a slow heating rate in the initial stage of power application and a continuous increase in surface temperature and power consumption were noted. The PTC-SHT consumed less power for heat generation than the NTC-SHT and exhibited rapid heating behavior in the initial stage of power application. The heat generation characteristics of the PTC-SHT were maintained at 95% after 100,000 cycles of 20% stretch–contraction testing, and the heating temperature remained uniformly distributed within ± 2 °C across the entire heating element. These findings demonstrated that an SHT with PTC characteristics is highly suitable for functional warm clothing applications that require low power consumption, rapid heating, stable warmth, and high durability.

ANALYSIS OF THE GENRE PALETTE F. KIESLER’S CREATIVE ACTIVITIES

Kiesler’s art was not based on the theory of form, color, and means; his art was not a political instrument to comment on the state of society, and he did not consider his art to be the product of a scientific process, a result that contained a truth that was absolute. He believed that his art revealed a truth that science could not see, and that truth was the key to a “core” existence. He believed that his process and his ritual were attacked by the deceptive beliefs of others. “A revived art that has been stolen from a warm embrace, freezing in its nakedness, cooled by the sweat of its forehead, desperately needs a new cloak so as not to freeze to death.” Kiesler’s environmental and galactic art, like its endless architecture, was warm clothing for art that desperately needed warmth.

An Unlikely Refuge: Latvia’s Women Volunteers in the Red Army in World War II

This article examines women’s wartime experiences with a focus on Latvia’s women volunteers in the Red Army in World War II. An estimated 8 percent of the Red Army was composed of women, who played a wide array of roles, including as snipers, combat engineers, medics, and frontline journalists. This level of female participation was unique in World War II, but a close examination of the phenomenon shows that motives and means for entry into the Red Army at the beginning of the war were not uniform. Our examination of the case of women volunteers from the Latvian Soviet Socialist Republic reveals key factors that fed women’s fervent desire to “get to the front.” It shows particular ways in which the Red Army functioned as an unlikely refuge, sheltering women from some of the hardships and threats of life in the Soviet Russian interior, including hunger, loneliness, and a lack of warm clothing, while providing a means of exacting revenge against a mortal enemy. At the same time, it exposed women to extremes of violence and conflict. Dominant Soviet narratives of women in war have presented them in largely marginal roles or have silenced stories that failed to comport with triumphalist and masculine representations of World War II. This work uses the voices of women volunteers in the Latvian Riflemen’s Divisions of the Red Army to construct an agent-centered history of motives, experiences, and memories.

Types of Winter Clothing Worn by Descendants of the Russian Pioneers in Siberia (Late 19th to Early 20th Centuries)

Warm clothing was an important cultural adaptation, enabling the Russian pioneers to survive in the harsh climate of Siberia. The sources for the study are archival documents, including V.K. Multinov’s manuscript “Clothing of the Angara People” (1926), results of fi eld studies in the 1970s and 1980s by the present author, museum artifacts, and collection inventories compiled by A.N. Beloslyudov, S.P. Shvetsov, I.I. Baranova, and I.I. Shangina, as well as data collected by climatologists, technologists, and designers. Types of winter clothing, including outfi ts for hunting and fi shing, worn by the Russians living on the Angara, in the Altai, and Trans-Baikal, are described. These include cloth-covered and non-covered fur coats, short fur coats, those with the fur on the inside, robes, as well as warm pants, fur hats, boots, and mittens. Protection from the cold was ensured by the use of high-volume insulating materials, several layers, and by habits such as tucking one piece of clothing into another (the so-called “Siberian one-piece garment”). Specific features in Siberia are observed, including the use in winter hunting outfi ts of certain elements of native Siberian clothing (specifi cally that of the Tungus clothing on the Angara), and the women’s habit of wearing men’s garments with belts.

Bonaparte’s Bursting Buttons: A Thin Story

On my way to Vilnius, capital of Lithuania, one late November I realized that I had not packed any winter clothes. It turns out that I was not the first to make this blunder. None of the half a million or so Germans, French, Swiss, Poles, Italians, and other nationalities who passed through the town or in its vicinity in June 1812 had packed any winter clothes, something many of them were to later regret. They were on their way, although they did not know it at the time, to Moscow. What they also did not know was that they were going to make what was arguably the world’s worst aller-retour journey ever: Vilna to Moscow and back (at that time the town was known under its Polish name and had recently been acquired by the Russians in the process of the annihilation of the Polish state). It was June, and they were in a good mood, as the Russian Tsar had recently fled Vilna followed by his quarrelling generals, and they were under the command of possibly the most competent military leader since Alexander the Great: Napoleon Bonaparte. The lack of warm clothing was not going to bother me, however. By the morning the snow had melted, and luckily I was not on my way to Moscow on foot. I was in Vilnius to search for some buttons, preferably made of tin. The story of Napoleon’s buttons and their allegedly fateful role in the disastrous 1812 campaign is widespread among scientists and science teachers. This is partly due to the popular book with the same name by the chemists Penny LeCouteur and Jay Burreson, and I wanted to find out whether there could be any truth in it, or whether it was just another of the legends and rumours that has formed around this war. Briefly, the story goes like this: metallic tin is a dense material (lots of atoms per cubic centimetre) and was supposedly the material used for many of the buttons of what was known as la Grande Armée. Unfortunately, metallic tin has a nasty Mr Hyde variation, known as grey tin.

Structure and Properties of Porous Bulked Tussah Silk and its Product

Tussah silk is a special product of China, which has luxury, ecological and health care advantages. Tussah silk is particularly suitable for the production of silk quilt, silk blanket, warm clothing and other products. In this work, porous bulked tussah silk fibers could be obtained through high temperature, high pressure, steaming explosion and puffing physical processing high-tech without any chemicals and assistants during degumming process. The surface morphology, size, porosity and mechanical property of the porous bulked tussah silk fibers were studied and compared with the ordinary tussah silk fibers. SEM results indicated that the bulked tussah silk fibers had porous structure. And the porous bulked tussah silk had higher elasticity and softness than the ordinary tussah silk fibers. Porous bulked and high elasticity tussah silk quit was produced from the ecotype porous bulked tussah silk fibers. The wearability of porous bulked tussah silk quilt was also investigated. The results showed that the insulating property, elastic recovery percentage and bulkiness of the porous bulked tussah silk quilt were all better than those of the ordinary silk quilt. As a result of the high resilience and flexibility of porous bulked tussah silk, the tussah quilt can effectively prevent the tangles and clumping of the silk fibers and is durable.

A Study of Wearabilities of Softwarm Heating Warm Fiber Fabric

With the improvement of people’s living standard, the traditional warm clothing already cannot satisfy people’s diversified demands about clothes’ comfortableness, functionality and aesthetics. Hygroscopic exothermic fibers as a positive heat production type of warm fibers have attracted much attention. Softwarm heating warm fiber is a kind of new functional material and at the same time it is a representative of hygroscopic exothermic fiber. It can absorb the moisture by skin breathe and transfer it into heat energy through chemical reaction so as to achieve the purpose of warmth. In this paper, warmth property, tensile property, and drapability of softwarm fiber plain knitted fabric were tested, and comfort property, mechanical property and appearance performances of softwarm heating warm fiber fabric were investigated. Our study showed that the wearability of softwarm fiber fabric is fine, especially the warmth property which can meet our needs of warmth to knitted underwear.

The Anglo-Latin elegy of Herbert and Wulfgar

A poem by a French monk named Herbert petitions Wulfgar Abbot of Abingdon for a gift of warm clothing. The poem, a mock epic employing alliteration and hermeneutic vocabulary, presents the seasons as warring deities. Using similar technique in the final eight lines of the poem, Wulfgar denies Herbert with a humourous response. This article contains an edition, translation, and analysis of the poem, along with brief biographies of the two authors. Another work by Herbert, a prosimetric letter requesting an allowance of fish, is edited and translated in an appendix.
