Elaboration of New Method of Deep Processing of Caro-tene-containing Raw Materials Into Nanoadditives with the Use of Cryogenic Freezing and Fine-dispersed Grinding

The aim of the work is elaboration of principally new cryogenic method of deep processing of carotene-containing vegetable raw material (CCVRM) such as carrot, pumpkin, sweet Bulgarian pepper, tomato, sea buckthorn, apricot using cryogenic freezing and fine-dispersed grinding.The new method of deep processing leads to more full extracting and removal of β-carotene from the state, bound with biopolymers into free and hydrophilic form. The mechanism of these processes was presented. It was established, that mass share of β-carotene in cryopuree, received by the new method, exceeds its content in initial (fresh) CCVRM in 3,0…3,5 times.The regularities of growth and transformation of carotenoids separately at freezing with different high speeds and low-temperature grinding of CCYRM were established. It was demonstrated, that at cryogenic freezing take place quantitative increase of mass share of carotenoids in 2,0…2,5 times comparing with initial (fresh) raw material depending on freezing speed and type of CCVRM. That is it was demonstrated, that frozen carotene-containing vegetable raw material contains 2,0…2,5 times more β-carotene than fresh one. Mechanism of these processes was presented.It was demonstrated, that cryopuree of CCVRM, received using new methods of deep processing, exceeds the initial (fresh) raw material by the content not only β-carotene but also other low-molecular bioactive substances: L-ascorbic acid – in 2,0…2,2 times, phenol compounds – in 1,7…1,8 times, tanning substances – in 1,5…1,7 times). That is they have principally new chemical composition, because practically all bioactive substances (BAS) in cryopuree are in nanosize form and easily assimilated by human organism

Economic-mathematical model for forecasting of Ukrainian educational industry market development considering demographic factors in accordance with the economy trends

Запропоновано економіко-математичну модель прогнозу розвитку ринку освітніх послуг України з урахуванням демографічних факторів відповідно до тенденцій змін в економіці. Для цього визначено фактори взаємовпливу ринку освітніх послуг та ринку праці, доведено, що важливою передумовою прогнозу розвитку ринку освітніх послуг з метою досягнення максимально можливого і в довготерміновому плані стабільного використання працездатного населення є баланс між демографічною ситуацією (демографічні фактори) і розвитком економіки (економічні фактори). Проведено аналіз переваг існуючих економіко-математичних моделей, що можуть бути застосовані до прогнозування розвитку ринку освітніх послуг України. Враховувати демографічні фактори запропоновано за допомогою методу пересування вікових груп, доцільність методу полягає в тому, що він дозволяє встановити не тільки чисельність, але й склад майбутніх фахівців. Економічні фактори описуються за допомогою павутиноподібної моделі, яка дозволяє описати перехід від однієї стійкої рівноваги ринку праці до іншої в тому випадку, коли в деякий момент часу при кожному значенні заробітної плати збільшується величина попиту на фахівців, і, як наслідок, на споживачів освітньої послуги зазначеної спеціальності. Економічні та демографічні фактори, які надають можливість переходу до стійкого економічного зростання та залежать від накопичення й використання людських ресурсів, враховуються в двосекторній ендогенній економіко-математичній моделі. Для кожної з моделей наведено функціональні залежності між складовими ринку освітніх послуг. Комплекс економіко- математичних моделей прогнозу розвитку ринку освітніх послуг, куди входять метод пересування вікових груп, павутиноподібна модель, двосекторна модель економічного зростання, представлений у вигляді відповідної схеми. Реалізація комплексу економіко-математичних моделей прогнозу розвитку ринку освітніх послуг дозволить визначити потреби економіки в робочих місцях із урахуванням коливань заробітної плати та очікуваннями щодо віддачі доходу, вкладеного в освіту.Economic-mathematical model for forecasting of Ukrainian educational industry market development considering demographic factors in accordance with the economy trends is proposed in this paper. For this purpose factors of mutual influence of the educational industry market and the labor market are determined, it is proved that an important condition for forecasting the educational industry market development in order to achieve the maximum possible and long-term sustainable use of able-bodied population is balance between demographic situation (demographic factors) and economic development (economic factors). The advantages of the existing economic-mathematical models that can be applied for forecasting Ukrainian educational market industry development are analyzed. It is proposed to consider demographic factors by means of technique of ageing, the relevance of this method is its ability to determine not only the number but also the list of future specialists. Economic factors are described by web-like model. It enables to describe the transition from one labor market stable equilibrium to another when at some point at each wage value the demand for specialists increases as well as for educational industry consumers of the specified specialty. Economic and demographic factors providing the possibility to move towards sustainable economic growth and depend on the accumulation and use of human resources are taken into account in two-sector endogenous economic-mathematical model. For each model, functional relationships between the components of the educational industry market are presented. A set of economic-mathematical models for forecasting of the educational industry market development including technique of ageing, web-like model, two-sector economic growth model is presented in the form of diagram. The implementation of economic-mathematical models set for forecasting of the educational industry market development makes it possible to determine the economy labour demand, taking into account wage fluctuations and expectations from the revenues invested in education

Noise Effects on Health in the Context of Air Pollution Exposure

For public health policy and planning it is important to understand the relative contribution of environmental noise on health compared to other environmental stressors. Air pollution is the primary environmental stressor in relation to cardiovascular morbidity and mortality. This paper reports a narrative review of studies in which the associations of both environmental noise and air pollution with health have been examined. Studies of hypertension, myocardial infarction, stroke, mortality and cognitive outcomes were included. Results suggest independent effects of environmental noise from road traffic, aircraft and, with fewer studies, railway noise on cardiovascular outcomes after adjustment for air pollution. Comparative burden of disease studies demonstrate that air pollution is the primary environmental cause of disability adjusted life years lost (DALYs). Environmental noise is ranked second in terms of DALYs in Europe and the DALYs attributed to noise were more than those attributed to lead, ozone and dioxins. In conclusion, in planning and health impact assessment environmental noise should be considered an independent contributor to health risk which has a separate and substantial role in ill-health separate to that of air pollution

Dynamics of platicons due to third-order dispersion

Dynamics of platicons caused by the third-order dispersion is studied. It is shown that under the influence of the third-order dispersion platicons obtain angular velocity depending both on dispersion and on detuning value. A method of tuning of platicon associated optical frequency comb repetition rate is proposed.Comment: 11 pages, 5 figure

Emerging countries as a future market leader

A modern world is changing very fast and the leadership of United States of America and Europe is becoming weaker than a few years ago. Nowadays some emerging countries are now trying to become the future economics‘ leaders. Such countries as Brazil, China and India have fast growing economies which will soon be even more effective than the western economies. They are taking more space in the international trade. This new dimension of the economy opens a lot of new opportunities to companies and organizations which are not afraid of investing abroad
