To date there are several ways to insulate shoes. Among them: the use of quality leather raw materials for the outer parts of the upper and natural fur for the inner parts of the upper of the shoe; application of insert insoles from heat-insulating foil; use of special insoles with a heating element Successful solution of the problem of heating the feet with the help of special insoles will diversify the range of shoes for the cold season, namely shoes for children, military, the elderly, people with impaired blood circulation in the vessels, hunters, fishermen and athletes. Currently, there are many imported thermal insoles on the footwear market, the prices of which are often too high for the average Ukrainian buyer. Therefore, it will be appropriate to make Ukrainian shoes of good design and good quality with special insert insoles at lower prices to meet the consumer needs of our consumers. It will also be possible to make only thermal insoles, which can be inserted into any shoe. Therefore, the topic of this scientific article is very relevant. The article analyzes all existing methods of heating the foot in warm shoes, considers the types of available insoles with heating. Such types of insole heating as chemical and mechanical are considered. Based on previously obtained experimental data, calculations were performed, based on which the required diameter of the wire to be used for heating the insoles was determined. The principles of production of insoles with a heating element which will be used for heating of feet in the cold period of the year are stated. An inexpensive foot heater has been developed, namely, an insole with a heating element made of wire cantaloupe A-1 with a diameter of 0.46 mm, which can be activated from absolutely any type of battery, from laptops, Powerbank, etc.

This chapter challenges traditional views on Iron Age dress. Recent research has greatly enhanced our understanding of how textiles were manufactured in Iron Age Europe. The variety of qualities, textures, techniques, raw materials, colours, and cuts give insights into the detailed knowledge of the craftspeople involved. Textiles used for dress, blankets, or furniture fittings were appreciated not only for their appearance, but also for the quality of the work. In everyday life, their optical qualities were used to express and signal gender, social roles and status, while the labour expended on textiles found in wealthy burials underlines both the status of the deceased and the extent of conspicuous consumption in funerary rituals—for instance, for wrapping grave furniture and goods. The chapter also looks at experimental data showing how labour-intensive textile production was, and the types of clothing and accessories found in different archaeological contexts or depicted in visual representations.

High pressure processing (HPP) is a cold pasteurization technology by which products, prepacked in their final package, are introduced to a vessel and subjected to a high level of isostatic pressure (300–600 MPa). High-pressure treatment of fruit, vegetable and fresh herb homogenate products offers us nearly fresh products in regard to sensorial and nutritional quality of original raw materials, representing relatively stable and safe source of nutrients, vitamins, minerals and health effective components. Such components can play an important role as a preventive tool against the start of illnesses, namely in the elderly. An overview of several food HPP products, namely of fruit and vegetable origin, marketed successfully around the world is presented. Effects of HPP and HPP plus heat on key spoilage and pathogenic microorganisms, including the resistant spore form and fruit/vegetable endogenous enzymes are reviewed, including the effect on the product quality. Part of the paper is devoted to the industrial equipment available for factories manufacturing HPP treated products.

As people age and engage with life, many people drop the commitments in things which become like a routine that they go on with There are many patients forget to take their treatment on time, while some of them take the treatment but in irregular schedules, which reduces the effectiveness of the treatment. The method of reminding patients their schedules by the nurse for the elderly and sitter kids is not considered a successful solution in some cases, because it relies on another person, who may probably omit or forgets the exact time. With the proliferation of smartphones, it requires a technology solution to help patients in determining medication schedules accurately and make them more controlling on taking their medication.             This paper proposed an application running on the iPhone connecting with smart drawers through the Arduino Board. The primary purpose of this application is to organize and remind patients to take their medicines on the accurate time. Drawers can be opened and closed through the application.

ObjectiveTo investigate the acute effect of air pollutants on ischaemic stroke (IS) and IS-related death.SettingFive urban districts in Changzhou, China, between 9 January 2015 and 31 December 2016.ParticipantsA total of 32 840 IS cases and 4028 IS deaths were enrolled.Main outcome measuresA time-series design, generalised additive model and multivariable regression model were used to examine the percentage change (95% CI) in daily IS counts and deaths with an IQR increase in air pollutant levels for different single or multiple lag days in single-pollutant and two-pollutant models.ResultsDaily IS counts increased 0.208% (95% CI 0.036% to 0.381%) with an IQR increment in the levels of nitrogen dioxide (NO2). The estimated risk of NO2was more robust in males and in the cold season. For daily IS counts, the estimated effects of NO2and sulfur dioxide (SO2) were more significant when adjusted for particulate matter with aerodynamic diameters <2.5 µm (PM2.5) and PM10. An IQR increment in the concentration of PM10, SO2and NO2significantly increased IS deaths with 6 days of cumulative effects (0.268%, 95% CI 0.007% to 1.528%; 0.34%, 0.088% to 0.592%; and 0.263%, 0.004% to 0.522%, respectively). Young individuals (<65 years old) had a higher IS mortality risk for PM2.5, PM10, NO2and CO. For IS death, the effect estimates of SO2in the elderly, females and the cold season were more pronounced; statistical significance was also identified for SO2when adjusted for carbon monoxide (CO).ConclusionsThis study suggested that short-term exposure to ambient NO2was associated with increased IS risk. In addition, SO2was associated with increased IS onset and death.

Osteoarthritis is one of the most common diseases of the connective tissue of the elderly. It was found that most epidemiological studies used the Kellgren and Lawrence system for classification of osteoarthritis, which indicates one of the 5 degrees (0–4) of osteoarthritis in various joints according to the radiographic atlas. It has been proven that chondroprotectors are represented by the following active substances: chondroitin sulfate, glucosamine sulfate or hydrochloride, hyaluronic acid, glycosaminoglycans, extraction preparations from animal or plant raw materials. The sources of raw materials for the manufacture of combined chondroprotectors are known, methods for their preparation and use are described. The main drugs on the chondroprotective market are presented. The effectiveness of their use for the treatment of osteoarthritis has been proven. It was found that preparations containing chondroitin sulfate have anti-inflammatory activity, affecting mainly the cellular component of inflammation, stimulate the synthesis of hyaluronic acid and proteoglycans. Methods of treating osteoarthritis using cell therapy (the use of readily available, highly proliferative, and multipotent mesenchymal stromal cells) are presented.

Unique biological quality of Mongolian livestock that helps the animal withstand the cold and feed shortage seasons in despite of feeding pasture plants only for all year round is an evidence of its pasture usability. Better growth of hair and wool of hardy Mongolian livestock, which are able to grow under severe natural and climatic conditions, during summer and autumn, and fibers appeared around the hair base during cold season make the animals resistant to cold. Mongolia has a long tradition of raising livestock in the vast territory. This is based on a system of pastoral herding consisting of five kinds of livestock. Mongolians have specific, historical traditions of nomadic ways for pastoral animal breeding. Since ancient times they are bred the five kinds of livestock with unique capabilities, adapted to four seasons grazing under harsh natural and climatic conditions of Central Asian mountainous and used their benefits. Although Mongolian livestock breeds are well adapted to harsh weather conditions, their productivity is not especially high. Animal husbandry is the fundamental source of food consumption and raw materials for the national economy, contributing 20% of the total GDP. Livestock workers make up 34.5% of the total labor force. The livestock sector is responsible for 90% of total agricultural production and comprises 12.5% of all exports. Currently, Mongolia has: 2 breeds and 2 strains of horses, 4 breeds of camel, 3 breeds and 1 breeding group of cattle, 13 breeds, 3 breed groups and 3 breeding races and 3 strains of sheep and 7 breeds, 4 strains of goats forming genetic resources of Mongolian livestock. The main products of the livestock sector are meat, milk, wool, cashmere and hides. Due to the harsh climatic conditions of Mongolian livestock, their wools grow well in the summer and autumn, and during the cold season, cashmere is covered with cashmere and they are resistant to cold. Mongolians have specific historical traditions of managing nomadic husbandry of five types of livestock populations, which are adapted to all year round grazing under severe natural and climatic conditions of Central Asian plateau, growing and breeding of wealth producing livestock populations and utilizing their animal products since ancient times.

В технике при изучении кинетики измельчения материалов пользуются математическими моделями в виде интегро-дифференциальных уравнений, решение которых трудоемко и не всегда приводит к получению наглядных результатов. Цель настоящей статьи разработать математическую модель, раскрывающую кинетику изменения фракционного состава измельчаемых древесных материалов, позволяющую на практике проводить оценку фракционного состава обрабатываемого сырья во времени. Методы исследования математический анализ, численные методы решения дифференциальных уравнений и обработки расчетных данных. Измельчение рассмотрено как многостадийный процесс, при котором фракции материала (узкие классы) под воздействием рабочего органа машины-измельчителя претерпевают превращения, происходящие как последовательно, так и параллельно, причем скорости превращений и доли вновь образованных узких классов материала определяются исходными размерами измельчаемых фракций и параметрами рабочего органа измельчителя. Предложена система дифференциальных уравнений, описывающая в общем превращения узких классов при измельчении, причем коэффициенты уравнений позволяют учесть произвольный вид функций скоростей измельчения фракций и выхода продуктов измельчения. Предложенная система является альтернативой интегро-дифференциальному уравнению балансовой модели измельчения. Выполнена оценка значений параметров математической модели на примере измельчения коры. По результатам сопоставления результатов моделирования с экспериментальными данными, полученными предыдущими исследователями, установлено, что предложенная дифференциальная модель изменения фракционного состава материала при принятых предпосылках к расчету ее параметров качественно и количественно описывает экспериментальных данные с высокой точностью. In techniques at study of kinetics of shredding of materials use mathematical models in the form of the integral-differential equations, which solution is laborious and not always leads to reception of evident results. The purpose of this article is to develop a mathematical model, which reveals the kinetics of change in fractional composition of wood materials being shredded, allowing in practice to evaluate the fractional composition of the processed raw materials in time. Methods of research include mathematical analysis, numerical methods for solving differential equations and processing of calculated data. Shredding is considered as multistage process at which fractions of a material (narrow classes) under the influence of a working body of the shredder machine undergo transformations occurring both consistently and in parallel, and rates of transformations and a share of again formed narrow classes of the material are defined by initial sizes of shredded fractions and parameters of the working body. The system of the differential equations describing in the general transformation of narrow classes at grinding is offered, and factors of the equations allow to consider any kind of functions of speeds of grinding of fractions and the output of shredding products. The proposed system is an alternative to the integral-differential equation of the balance shredding model. The estimation of values of parameters of the mathematical model on an example of bark shredding is carried out. By results of comparison of results of modeling with the experimental data received by previous researchers it is established that the offered differential model of change of fractional composition of the material at the accepted preconditions to calculation of its parameters qualitatively and quantitatively describes the experimental data with high accuracy.
