Abstract:

A number of environmentally hazardous substances are used in the process of flax roving preparation for spinning. An alternative to them can be the use of electrochemical activated aqueous solutions. However, the metastability of such solutions requires time tracking of their properties’ relaxation. This article pre-sents experimental data on the relaxation of relevant solutions that can be used for a well-founded selection of flax roving treatment procedures to ensure a re-quired quality of flax yarn. It has been experimentally proven that the use of ECA solutions for preparing rovings for spinning allows to obtain high quality yarn as well as significantly reduce wastewater pollution and improve the envi-ronmental situation in the places of their emissions.

Abstract:

Wood processing soft waste is mainly used in the production of fuel briquettes, irrecoverable (non-recyclable) waste from spinning flax and cotton are incinerated or sent to dump. The development of methods for recycling non-recyclable cellulosic waste through the product manufacturing is relevant, both from the resource conservation perspective, as well as the environmental point of view. The issues of plant waste recycling through the manufacturing of various types of products are widely developed in the Russian and foreign scientific research practice. Researchers deal with the processing of wheat, rice straw, bamboo stalks, and other cellulosic materials. There is a plenty of published information on methods of soft wood waste recycling. However, no research on recycling irrecoverable waste of spinning flax and cotton fibers had been carried out before this paper. We propose to produce thermal insulation boards based on phenol-formaldehyde resol binder using flax and cotton spinning waste and soft wood processing waste. The wet production method used here involves mixing the filler with water, a precipitant solution and a binder. After spinning the material is dried. The paper presents the results of determining the physical and mechanical properties and thermal conductivity coefficient of boards made of plant waste. The research was carried out according to the B-plan of the second order. Adequate regression mathematical models of the dependences of physical and mechanical parameters of the boards on the varying factors of the production process were developed according to the experimental data processing results. Using the developed regression models we built the response surfaces of the composite parameters: the bending strength of the boards, the thickness swelling of the boards after 24 h of exposure in water and the thermal conductivity coefficient. Nomograms of the dependencies of board parameters on the values of varying factors have been developed based on the mathematical models analysis. The nomograms are the basis for the development of practical recommendations for determining the rational values of the parameters of insulation board materials production from irrecoverable waste of spinning flax and cotton and soft wood processing waste.

Abstract:

Limited studies exist related to the siro-spun spinning of flax ( Linum usitatissimum L.) and cotton (Gossypium hirsutum) blends. The purpose of this study was to determine the influence of various siro-spun processing parameters, including twist factor, space between two rovings and specification of traveler, on yarn qualities, such as yarn hairiness, tenacity and evenness. Results show that both specification of traveler and space between two rovings significantly influenced yarn hairiness and evenness, and heavier traveler and greater space led to decreased hairiness, but bad evenness. Twist factor influenced yarn evenness highly significantly, and smaller twist factor led to worse yarn evenness. Results also indicate the optimum levels of siro-spun process parameters as follows: twist factor αm = 150, space between two rovings 8 mm, traveler Fo 5/0. In relation to the general ring-spinning yarn, the siro-spun spinning yarns had decreased hairiness, little increased tenacity and similar evenness.

Abstract:

Изучение линий и номеров на всех этапах селекционного процесса проводилось в 1995–2004 и 2021–2022 годах на опытных полях ФНЦ ЛК в Торжокском районе Тверской области. Целью проводимых исследований было создание и передача на государственное сортоиспытание нового сорта льна-долгунца, сочетающего высокую продуктивность с устойчивостью к наиболее вредоносным грибным заболеваниям и полеганию. Лён-долгунец является исконно русской сельскохозяйственной культурой комплексного использования, максимально адаптированной к почвенно-климатическим условиям России. Благодаря уникальным природным гигиеническим и эксплуатационным свойствам льняная продукция является перспективным сырьевым материалом для использования в различных секторах экономики. Созданные за последние годы сорта льна-долгунца (Надежда, Визит, Сурский, Добрыня, Импульс и другие) характеризуются высоким содержанием волокна в технической части стебля (27–30% и более) и высокой потенциальной его урожайностью (2–2,5 т/га), комплексной устойчивостью к наиболее вредоносным грибным заболеваниям (ржавчине и фузариозному увяданию). Волокно ряда сортов (Надежда, Визит и др.) обладает высокими прядильными свойствами. Вместе с тем сорта, возделываемые в настоящее время в льносеющих хозяйствах, не в полной мере удовлетворяют потребности перерабатывающей промышленности в сырье с определёнными технологическими свойствами. Селекционная линия П-183, планируемая как новый сорт, обеспечивает получение высоких урожаев семян (1,24 т/га) и волокна (2,13 т/га) с высоким качеством (номер 12,4). Создаваемая линия высоковолокнистая, содержание волокна в технической части стебля составляет 29,3%. Линия высокоустойчива к ржавчине (99,3%) и полеганию (4,9 балла), устойчива к фузариозному увяданию (70,7%) и антракнозу (51,5%). The testing of lines and genotypes of flax was conducted at the trial fields of the Federal Research Center of Fibre Crops in the Tver region in 1995–2004 and 2021–2022. The aim of this research was to breed the high-productive variety of flax resisting the most virulent fungi and lodging to be later sent to the State Variety Trial. Flax is a multipurpose crop that is very common in Russia and well-adapted to the conditions of the country. Due to their unique sanitary and economically important traits flax products are promising raw materials to be used in various spheres. The lates varieties of flax (Nadezhda, Vizit, Surskiy, Dobrynya, Impuls etc.) have high fiber content in stem (27–30% and more), potential productivity (2–2.5 t ha-1), as well as resistance to rust and fusarium wilt. The fiber of some varieties (Nadezhda, Vizit etc.) show excellent spinning properties. At the same time, currently cultivated varieties do not fully satisfy the needs of the processing industry. The P-183 line (putative new variety) provides high seed yield (1.24 t ha-1) and top-quality (No. 12.4) fiber (2.13 t ha-1). The line shows high fiber content — 29.3%. It tolerates rust disease (99.3%), lodging (4.9 points), fusarium wilt (70.7%) and anthracnose (51.5%).

Abstract:

Due to the ever-growing demand for bast fibres for technical and garment textiles, complementary sources to textile flax, whose cultivation in western Europe cannot really be extended, need to be proposed. In this study, the interest in harvesting and processing linseed flax straw is studied for geotextile applications. The main critical stages of fibre-to-yarn production for geotextiles were investigated. Different dew retting levels as well as different all-fibre extraction processes were investigated to achieve this objective. It was demonstrated that the fibres extracted from linseed flax stems subjected to 12 weeks of dew retting using breaking rollers, thresher and a breaking card exhibited the most suitable morphological and mechanical properties. The optimal fibres were converted into 100% linseed flax yarns using a flyer spinning machine, and the mechanical properties as well as the biodegradability of the linseed yarns were evaluated to understand their potential as geotextiles. These linseed flax yarns were further coated with linseed oil or chitosan to enhance their durability. It was observed that the linseed oil coating better preserved the yarn’s integrity and mechanical properties over time, and it permitted doubling their service life potential.

Abstract:

Abstract The elaborated principles of nanoengineering of linen textile materials implement the techniques of spatially localized effects of protein catalysts on polymeric cellulose companions with selective splitting of impurity compounds without damaging technologically necessary nano-sized formations of binders in the fiber structure. The ranges of optimal values of the residual content in flax fiber prepared for spinning are identified on the basis of the analysis of the successive stages of enzymatic and peroxide treatments contribution to the breakdown of polymers and the differentiation of the influence of impurities on the yarn technological properties. The recommended level of residual pectin, lignin and hemicellulose (wt. %) is: after enzymatic treatment P1 = 1,0±0,1; L1 = 3,9±0,3; Hc1 = 11,0±1,0; after peroxide bleaching P2 = 0,4±0,05; L2 = 2,3±0,3; Hc2 = 7,5±0,5. The required level of fiber structural modification at the stage of preparing roving for spinning can be achieved through use of protein catalysts whose globule size is 50...100 nm. The use of enzymes with these dimensional characteristics helps to ensure breaking of polymer adhesives on the surface of incrusts and in the areas of intercellular formations, which hinder fiber crushing, without damaging nano-sized binding fractions. The implementation of this method contributes to a significant improvement in the uniformity of structural and physical and mechanical properties of flax yarn. Increase in yarn fineness and strength properties of semi-finished products, as well as improvement of deformation properties and reduction of yarn breakages during the spinning processes are achieved.

In space, the Castreña culture was located in the north-western part of the Iberian Peninsula, whereas in time it stretched from the Late Bronze Age to the beginning of the Roman period. This study focuses specifically on the invention and use of the spinning bowl in the Castreña culture. Theoretical and conceptual tools will enable tackling this item with a rigid research methodology and help answer the question of why the invention of the spinning bowl and the innovations in processing of flax yarn production occurred, and how they were transmitted to other areas in the forms of innovation or technical loan. To explain its presence within the limits of this geography and chronology, the use of Linum usitatissimum L. is discussed. This specific raw material is closely related to the entire innovation process on the one hand, and on the other opens an avenue for research into its function within the technical chain of the creation of linen thread or yarn.

Abstract:

The existing problem of cotton import substitution ensures the relevance of modified flax fiber production. Modified flax fiber has potential uses in textile manufacturing when mixed with cotton or similar fibers in order to produce non-woven textile materials, as well as armature for biocomposite materials. As such, it is necessary to alter the existing methods of determining modified flax fiber quality in order to pick new quality metrics corresponding to the changes to fiber's structure during processing. In particular, average thickness and length of the modified flax fiber suffer a degree of reduction during fiber's preparation for spinning, which needs to be measured and taken into account. As the result of the research there was proposed the way to estimate the fractioning quotient of modified flax fiber via sliding bending against rounded edges imitating the effects of actual fiber processing. When working parameters and edge geometry are constant, fiber thickness is reduced by ∆ = Torig - Tres. For fiber with thickness Torig in range of 0.109 to 0.135 micrometers the value of ∆ differes from approximately 0.010 to 0.098 micrometers. It was suggested to estimate the fractioning quotient according to value of D = 100·∆ / Torig. During experimental testing of this method using various quality fiber produced in Tver region and Udmurtia Republic the value of D was varying from 0.10...0.15 % to 7.3...7.7 %. It has been established that the suggested method with the use of standard indicator «fiber thickness» enables to take into account the strength of inter-fiber connections according to the currently accepted theory of their formation. Applying this method makes it possible to differentiate full-scale shipments of modified flax fiber using sliding bending stress performed under identical conditions.

Abstract:

Many plant wastes are not currently used in production, they are disposed of in landfills or incinerated. The aim of this study is to develop a composite thermal insulation material from unused spinning waste of flax and cotton fibers and soft wood waste. Samples of thermal insulation materials from plant waste were made by drying using the technology of production of soft wood fiber boards. For composite board defined physico-mechanical characteristics and thermal conductivity. The experiment was carried out according to a second-order plan, regression models of the dependences of the material indicators on the proportion of the binder additive, drying temperature and the proportion of wood waste additives were developed. The study showed that composites from unused spinning waste of plant fibers and soft wood waste have the necessary strength under static bending, the swelling in thickness after staying in water is much lower in comparison with the performance of boards from other plant fillers. The coefficient of thermal conductivity of the boards is comparable with the indicator for mineral wool boards.

Abstract:

This article explores the needlework practices of a provincial gentrywoman in mid-nineteenth century Russia. Natal’ia Chikhacheva (1799-1866) managed her family’s modest estates in Vladimir province, in the heart of the textile region surrounding the village of Ivanovo. She oversaw serf labor in textiles, especially the growing and processing of flax and weaving, but she also did spinning, knitting, sewing, and lacemaking herself. The products of her needles were used not only by her own family, but also by their serfs, while some were sold for profit or given as gifts to friends. Chikhacheva provides a rare glimpse of everyday Russian needlework of the period, its uses, and cultural associations.

Abstract:

This article presents a spinning and weaving vocabulary based on the material of the historical Russian language dictionaries and on the ancient manuscripts containing colloquial and business lexis. It describes two large groups of words connected with the designation of the actions ‘pryast’’ [to spin] and ‘tkat’’ [to weave]. They comprise not only cognate words like ‘pryast’’ [to spin],‘pryakha’ [a spinner], ‘pryalka’ [a spinning wheel], ‘pryazha’ [yarn], ‘pryadilshchik’’ [a male spinner] (the first group), and ‘tkat’’ [to weave], ‘tkan’’ [cloth], ‘tkach’ [a male weaver], ‘tkachikha’ [a female weaver] (the second group), but also other purpose-specific lexis. Special attention is placed on the fact that these two groups include the names of persons (‘pryakha’ [a spinner], ‘pryadeya’ and ‘pryaljya’ which are both obsolete words meaning [a spinner], ‘pryadilshchik’ [a male spinner],‘tkach’ [a male weaver],‘tkachikha’ [a female weaver], ‘tkaljya’which is an obsolete word meaning [a female weaver],‘tkatel’’which is an obsolete word meaning [a male weaver],etc.), names of materials (‘lyon’ [flax], ‘konoplya’ [hemp], ‘kudel’’ [tow], etc.), labor actions and processes associated with their processing (‘terebit’’ [to pull], ‘myat’’ [to break], ‘trepat’’ [to skutch], ‘suchit’’ [to twist], etc.), as well as the processing waste (‘kostrika’ [chaff], ‘otryopki’ [hurds], ‘paklya’ [rug skutching], etc.), instruments of labor (‘myalka’ [a breaker], ‘pryalka’ [a spinning wheel], ‘vereteno’ [a spindle], ‘stan’ [a body], etc.), products of labor (‘pryazha’ [yarn], ‘polotno’[canvas], ‘poskon’’ [hemp cloth], etc.). This article analyzes the origin of these words and their subject orientation. Having compared the functioning of the terms of spinning and weaving production in the Russian literature records with the colloquial and slangy lexemes associated with them in modern speech communication, we came to a conclusion that the latter acquired purely attitudinal meaning.

Abstract:

The mythological character “kikimora” is considered on ethnographic materials ofvarious ethnolocal groups of Russians in Western Siberia. Kikimora was considered a character in the home space, mostly malicious, harmful, sinister. Kikimora was spinning. Therefore, she was associated with the symbolic embodiment of destiny: a deity that spins and breaks the thread of life. Kikimora embodied the trickster archetype. The concept of kikimora correlates with the symbols of time. “Border” periods are especially significant: the change of day, the transition from the old year to the new year. Therefore, the masquerade image of the kikimora entered the calendar rituals of the winter-spring period. In Western Siberia, until the middle of the twentieth century, the tradition of dressing up in “kikimora” on Christmastide and Maslenitsa (“farewell to winter”) was preserved. Women dressed up in old shabby clothes, smeared their faces with soot: they created the image of a slob. Masquerade “kikimors” carried items of women’s handicraft: wool, flax, a spindle, a comb. Entering the house, they pretended to be spinning threads. The concepts of forest and swamp kikimora, widespread in the 20th and early 21st centuries, are probably associated with the erosion of this image in popular beliefs. Consciousness transferred the kikimora to a space far from the human cultural environment. Kikimora as a domestic demon, the spinning goddess disappears from popular beliefs, but is actualized in the forest and swamp spirits. The word “kikimora” is firmly entrenched in the Russian vocabulary to become a household name, a curse, while the characteristic features of the character have been preserved. The masquerade tradition in the twentieth century actualized the rudimentary idea of kikimora as a spirit spinning the thread of fate. However, the fundamental features of this character were lost: from the deity of destiny, kikimora turned into a playable character in genre scenes of Christmastide andMaslenitsa masquerades.

Abstract:

This research aims to analyze the environmental impact of six fibers in the textile industry: conventional and organic cotton, silk, jute, flax, and polyester. The study used a life cycle assessment (LCA) methodology with a cradle-to-gate system boundary and analyzed the stages of agriculture, spinning, weaving, and dyeing. In agriculture production, five impact categories (i.e., fossil resource scarcity, global warming, land use, terrestrial ecotoxicity, and water consumption) have the most significant differences across these fibers. Polyester production significantly impacted the terrestrial ecotoxicity impact category, while stratospheric ozone depletion had a minor impact. In yarn preparation and spinning, silk has the most significant impact in most categories, followed by conventional cotton, while jute had the most minimal impact. In weaving, the most visible differences were in fossil resource scarcity, global warming, land use, terrestrial ecotoxicity, and water consumption. Conventional cotton dyeing showed significant impacts on global warming potential and terrestrial ecotoxicity. This study contributes to the limited literature on existing LCA research in the textile industry. Adding updated information will help increase the comprehension of LCA research and guide stakeholders in transitioning fashion supply chains more sustainably.

Abstract:

The purpose of research is to study gelling substances (structure formers) and use them as a partial replacement for agar when developing a recipe and technology for preparing marmalade, as well as determining the quality of the resulting marmalade product. The object of the study is the seeds of long-stalked flax produced in 2020, grown in the fields of the Russian State Agrarian University – Moscow Agricultural Academy named after K.A. Timiryazev. The results of a study on the development of a recipe for jelly marmalade are presented. To obtain marmalade with beneficial properties, we partially replaced the gelling raw material (agar) with a jelly-like suspension obtained by blanching fiber flax seeds, and completely replaced sugar with a sweetener – stevia. A new marmalade product enriched with plant raw materials was obtained. Materials related to the physicochemical properties of long-stalked flax fiber, which is one of the best spinning crops and is used in the textile industry, were studied. At the same time, the following beneficial properties of flax were noted: the content of proteins with a complete amino acid composition; the content of polysaccharides, thanks to which it is possible to obtain a jelly-like suspension and use them as a gelatinous substance. Sugar was completely removed from the recipe and replaced with stevioside, a chemical compound present in the leaves of the stevia plant. To eliminate the bitter taste of stevioside, a decoction of red currant berries was used. A tasting was also held, as a result of which the product was highly appreciated. Based on research conducted, patents were obtained. The possibility of producing marmalade with beneficial properties under production conditions is presented. The resulting sweet product is safe for overweight people and people with diseases such as diabetes.

Abstract:

En este trabajo se analiza el importante conjunto de fusayolas procedentes del asentamiento de Cabezo Redondo, recuperadas tanto en las excavaciones antiguas de José María Soler como en las desarrolladas en las últimas décadas. El número elevado de ejemplares, todas ellas correspondientes a contextos del Bronce Tardío (c. 1600-1250 cal BC), y sus características (diversidad en materiales utilizados, tipología y peso) permiten inferir una actividad de hilado intensa distribuida a lo largo del poblado, así como importantes transformaciones en la producción textil con respecto a los momentos previos. Entre los cambios principales se encontrarían la continuidad de la tradición de hilado de fibras vegetales como el lino y, sobre todo, la consolidación de nuevas técnicas de hilado y la generalización del hilado de fibras de origen animal como la lana. En definitiva, a partir del estudio de estos artefactos, sumado al análisis de otros indicadores, se propone el desarrollo de una producción textil amplia y diversa, en sintonía con lo que sucedido en otras áreas de Europa y el Mediterráneo durante la segunda mitad del II milenio cal BC.

Abstract:

The structure and factors of the process of production of heat-insulating composite plate materials from the waste of spinning of plant fibers are being developed. A disadvantage of the cellulose-containing filler composites is their increased flammability. The stages of thermal destruction of cellulose are considered. To determine the characteristics of the material that affect their fire hazard properties, the differential scanning calorimetry method was used. The paper substantiates the use of the method of introduction of fire retardant at the stage of formation the structure of composite. To reduce the flammability of composite materials from plant raw materials, it was suggested to use ammonium fluoride. The results of the determination of the degree of damage by mass in the case of burning in a “ceramic combustion chamber” of samples of a composite material with filler from irrecoverable waste produced by cotton and linen fibers are obtained. It has been established that the use of ammonium fluoride for the manufacture of heat-insulating composite plate materials from the irrecoverable waste produced by cotton and linen fibers makes it possible to obtain material with a degree of damage by mass of not more than 22 %. Key words: cotton, flax, spinning waste, cellulose, thermal destruction, differential scanning calorimetry, composite materials, loss of mass in combustion, ammonium fluoride.

Indeed I found it difficult and tedious to bring them to this; but I believe it will now do.

Abstract:

The article deals with clay spindle whorls, special weights for spindles, necessary for spinning threads from various materials — wool, vegetable fibers (nettle, flax). They were found at the Tetyushy-II hillfort of the Imenkovo culture, in the Republic of Tatarstan. The hillfort was studied by K.A. Rudenko in 2007–2013. It differs from many other sites of the Imenkovo culture in its clear stratigraphy with dated layers. A total of 186 spindle whorls were found. This is currently one of the most representative collections of these artifacts from archaeological excavations at the settlements of the Imenkovo culture in the Kazan Volga region. According to the complex of features, 6 types of spindle whorls were distinguished. The typology is based on the shape of the product. Three types of these products, the shape of which is truncated-biconical, are the most common in the Imenkovo settlements. They differ in their sizes: small (diameter up to 2.6 cm), medium (diameter up to 3.5 cm) and large (diameter up to 5 cm). The objectivity of such a grouping is also confirmed by the weight parameters of these sections: small — up to 7 g, medium — up to 11 g, and large — up to 25 g. The dependence of the weight of the spindle whorls on the diameter of the channel through which it was put on the spindle whorls was revealed. At Tetyushy-II fortified hillfort, fragments of spindle whorls make up 33.8% of their total number and most often they are found in the lower horizon of the III — upper horizon of the IV layer, which were formed at the end of the 6th — the first half of the 7th century. There are few spindle whorls decorated with ornaments — 16% of the total. The most frequently decorated with ornaments (dots, crests, etc.) were medium-sized spindle whorls. Based on the materials of the Tetyushy-II hillfort and finds from the Imenkovo settlements located in the lower reaches of the Kama: Shcherbet’-I (island), the settlement, the settlements of “Kurgan” and “Devichiy Gorodok” and a number of others in the amount of 375 copies, methods for making Imenkovo spindle whorls. These products were made in 4 ways: from a blank in the form of a finished product; from a cylindrical billet with further sculptural refinement; from a ring blank with sculptural refinement; of three bundles, by winding onto a rod. For the first method, master models were probably used. Clay with an admixture of sand, sometimes fine chamotte and organic matter, and in some cases crushed shells of river mollusk shells was used for the manufacture of spindle whorls. It was found that in most cases the spinners were associated with buildings and were used in household crafts (spinning). Since the weight of the spindle whorls is small, then, apparently, several of them were put on the spindle, depending on the raw material for spinning. Thus, according to the materials of the Tetyushy-II hillfort, the systematization of the Imenkovo culture was carried out, for the first time methods of manufacturing were identified, the most characteristic types of these products for the 6th–7th centuries in the Kazan Volga region were determined.

Abstract:

In this talk, I present a theory of quantum gravity beyond Einstein. The theory is established based on spinnic and scaling gauge symmetries by treating the gravitational force on the same footing as the electroweak and strong forces. A bi-frame space-time is initiated to describe the laws of nature. One frame space-time is a globally flat coordinate Minkowski space-time that acts as an inertial reference frame for the motions of fields, the other is a locally flat non-coordinate Gravifield space-time that functions as an interaction representation frame for the degrees of freedom of fields. The Gravifield is sided on both the globally flat coordinate space-time and locally flat non-coordinate space-time and characterizes the gravitational force. Instead of the principle of general coordinate invariance in Einstein theory of general relativity, some underlying principles with the postulates of coordinate independence and gauge invariance are motivated to establish the theory of quantum gravity. When transmuting the Gravifield basis into the coordinate basis in Minkowski space-time, it enables us to obtain equations of motion for all quantum fields and derive basic conservation laws for all symmetries. The gravity equation is found to be governed by the total energy–momentum tensor defined in the flat Minkowski space-time. When the spinnic and scaling gauge symmetries are broken down to a background structure that possesses the global Lorentz and scaling symmetries, we arrive at a Lorentz invariant and conformally flat background Gravifield space-time that is characterized by a cosmic vector with a non-zero cosmological mass scale. We also obtain the massless graviton and massive spinnon. The resulting universe is in general not isotropic in terms of conformal proper time and turns out to be inflationary in light of cosmic proper time. The conformal size of the universe has a singular at the cosmological horizon to which the cosmic proper time must be infinitely large. We show a mechanism for quantum inflation caused by the quantum loop contributions. The Gravifield behaves as a Goldstone-like field that transmutes the local spinnic gauge symmetry into the global Lorentz symmetry, which makes the spinnic gauge field becomes a hidden gauge field. As a consequence, the bosonic gravitational interactions can be described by the Goldstone-like Gravimetric field and space-time gauge field. The Einstein theory of general relativity is expected to be an effective low energy theory. Two types of gravity equation are resulted, one is the extension to Einstein’s equation of general relativity, and the other is a new type of gravitational equation that characterizes the spinnon dynamics.

Abstract:

The lower curing temperature of phenol formaldehyde binder allows reducing the costs of producing cellulose-containing materials, such as FSF plywood and thermal insulation composites made of plant wastes. However, the low-temperature production mode provides an insufficient degree of the phenol formaldehyde binder curing, leading to a decrease in water resistance of material based on the phenol formaldehyde binder. A modifier should be added to the phenol formaldehyde binder to reduce the amount of free hydroxymethylol groups in the cured binder and to form a stronger cross-linked structure in low-temperature curing conditions. Hydrogen peroxide was used as a phenol formaldehyde binder modifier in this research. The research results confirmed the hypothesis about the effect of hydrogen peroxide on the intensification of the structure formation of cellulose-containing materials based on the phenol formaldehyde binder. In conditions of low-temperature curing (120 °C for FSF plywood and 100 °C for thermal insulation composites made of plant wastes) modification of phenol formaldehyde binder with hydrogen peroxide reduced the binder curing time, the pressing time of FSF plywood, improved the physical and mechanical properties of FSF plywood and thermal insulation composites made of cellulose-containing filler (soft wood waste and irrecoverable flax spinning waste). When 1.0 % of hydrogen peroxide is added to the binder, the binder curing time reduces by 43.6 %. The addition of 1.0 % of hydrogen peroxide increased the shear strength of FSF plywood by 4.4 % and the static bending strength of plywood by 4.8 %. Modification of the binder with hydrogen peroxide increased water resistance of FSF plywood: plywood thickness swelling has been reduced by 2 % over 24 h in water. The strength of thermal insulation composites made of cellulose-containing wastes increased by 5.2 % with the addition of 1.0 % of hydrogen peroxide, thickness swelling decreased by 4.9 % over 24 h. The obtained research results allow recommending a modifying additive of hydrogen peroxide to phenol formaldehyde binder in an amount of 1.0 % of resin mass to increase the strength properties of FSF plywood and thermal insulation composites made of plant wastes.

Then, to extend the Mathisson–Papapetrou equations to R-Minkowski space–time, that correspond to de Sitter space–time given by a conformally flat metric, it was necessary to determine the Killing vectors, which allowed us to find the equations of motion that describe the dynamics of spinning particles.

Abstract:

Effect of Droplet Size on Weed Control in WheatThe efficacy of different water volume and nozzle systems, comprising spinning-discs with two disc speeds (low volume, LV), a spinning-cage rotary atomizer (median volume, MV), a flat fan nozzle Teejet-11004 (high volume, HV), and no weed control, were assessed for the application of 2,4-D to control weeds in irrigated wheat. The herbicide was applied at the tillering stage of cultivated wheat, Ghods variety. Sprayer nozzle performance was evaluated in terms of wheat grain yield, weed shoot biomass, and wheat residual (straw), at the research farm of Shahrekord University in 2007 and 2008. ANOVA analysis indicated that nozzle type, and the year had significant effects on grain yield and dry biomass of weeds at 5% confidence. There was a significant difference between the two years of the experiment for all variants. The results indicated that the median diameter volume using the spinning disc (low disc speed) for herbicide application, gave better weed control than others. The spinning disc nozzle decreased water use and so it was cheaper to operate. It did not, however, significantly improve herbicide efficacy, especially in dense canopies compared with the conventional flat fan nozzles. The spinning-disc had more droplet uniformity at high disc speeds compared with the cage rotary atomizer, but was more effective for weed control at low disc speeds.

Abstract:

Electrospinning (e-spinning) has been widely applied to fabricate flat films accumulated by microfibers for tissue engineering. In order to acquire an uneven surface morphology, two methods have been applied traditionally. The first uses a designed receiving substrate, which is stable, but suppresses the flexibility. The second uses dual solvents to achieve bimodal distribution of the fiber diameter. However, the bimodal fiber diameter causes inhomogeneity. To solve these challenges, cryogenic electrospinning, using a flat substrate and a single solvent, was performed in this study to obtain uneven films. By applying a low temperature to the flat receiving substrate, uneven e-spun films with wall-like structures were achieved through the self-assembly of uniform filaments. In addition, the wall-like structures enhanced the mechanical properties of the e-spun films. Moreover, the cryogenic e-spinning produced micropores on the fiber surface, which have the potential to promote esophageal epithelial cell adhesion, proliferation and differentiation.

We discuss the basic properties of a class of static and spinning black ringoids (Br) in d = 7 spacetime dimensions. These asymptotically flat solutions of the vacuum Einstein equations possess an S2 × S3 event horizon topology. They are found for a specific metric ansatz and can be viewed as natural higher dimensional counterparts of the d = 5 black rings (BRs). Similar to that case, the static configurations are supported against collapse by conical singularities. We provide evidence for the existence of balanced solutions which are spinning and possess two equal magnitude angular momenta.
