Private Equity and Devaluation in Emerging Countries
Authors: Herrera-Echeverri Hernán , Haar Jerry , Salazar-Duque Juan Guillermo
Published: November 2017

Abstract:

Using a comprehensive database with 51 emerging countries studied over a 13 year period, we find that devaluation increases the PE investment. More years of annual devaluation have a higher impact in promoting PE investment. Conclusions are confirmed for total and high technology PE investments, but not for early stage PE investments. Devaluation does not benefit PE investment in firms in the early stages of development. Devaluation itself is not sufficient to encourage the appetite of investors; however, some country-level competitiveness variables are indispensable for making a country more fertile for PE investment when a devaluation occurs – the high relevance of competiveness increasing in the long term.
Robust Optimal Design of Working Fluids for Sustainable Low Temperature Energy Recovery Under Uncertain Conditions

Published: November 2017

Efficient energy recovery is one of the key technological strategies for coping with reduction and emission of green-house gases. Commonly, such gases are produced during combustion of fossil fuel-based processes. A way to contribute to reduce the emission of green-house gases has to do with energy recovery from low-temperature energy sources, commonly available in industrial processing systems, deploying both mixtures of organic fluids and power Rankine cycles. However, feasible optimal design calls for taking into account uncertainty both in model and process parameters. In this work we propose a robust optimal design approach, based on nonlinear programming, for addressing efficient energy recovery from low-temperature sources which takes advantage of the presence of uncertainty to render optimal processing conditions realizable in practice. The proposed robust optimal approach is particularly suitable when no probability distributions of uncertainty are available and only upper and lower bounds on uncertainty are known. Three case studies are presented to stress the importance of considering the impact and presence of uncertainty on low-temperature Rankine cycles.

Published: November 2017

A closed-type water source heat pump dryer integrated with a drying programme (DP) was designed and tested. The DP was developed using psychometric conditions of desired drying air and thermodynamic balance of heat pump. A drying algorithm was developed according to the technical specification of the dryer. Drying air temperature, relative humidity and drying air volumetric flow rate were entered from a programmable logic controller (PLC) screen. In this study, the drying of mint leaves was examined. Mint leaves were dried at different temperatures (35°C, 40°C and 45°C) and at different volumetric flow rates 300 m3/h for a velocity of 0.75 m/s and 600 m3/h for a velocity of 1.5 m/s in the PLC-controlled heat pump dryer. The relative humidity of the drying air entering the dryer chamber was kept between 13.88% and 6.81% and the two air dampers were controlled according to predetermined value. The coefficient of performance (

Published: November 2017

In China, there are about 1.6 million tons of thinned young apples (TYAs) every year after blossoming and fruit thinning. These resulting fruits, in reality, could be utilized as agricultural and food resource. This study was undertaken to evaluate the influence on physical properties, bioactive attributes of TYAs that were subjected to chosen drying techniques. In general, significant differences (p < 0.05) exist in physical appearance and polyphenol. Antioxidant capacity was also investigated on the basis of assay for Trolox equivalent antioxidant capacity (TEAC) by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), reducing power and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging ability. Judging from the results, it was concluded that hot air drying at 60℃ is appropriate for large-scale production; furthermore, vacuum freeze drying tends to manufacture high-value up-market TYA products that are available to give the best results for dehydrated fruits. It is suggested that TYA has great potential in the food industry as functional ingredient.
Foreign Aid, Law Reform, and the World Bank’s Doing Business Project
Authors: Yackee Jason Webb
Published: November 2017

Prominent socio-legal scholars have criticized the World Bank’s Doing Business Project on the grounds that development aid donors improperly condition aid on compliance with Doing Business norms. This paper provides the first empirical test of that thesis. I examine nearly a decade of development assistance to analyze whether developing countries that implement more Doing Business reforms indeed tend to receive more development aid. I find mixed support for the conditionality thesis. While aid from multilateral organizations and from the World Bank’s International Development Assistance (IDA) program are correlated with reform efforts, total aid, as well as aid from rich countries, is not.
Seeing Things with Your Own Eyes: Steven Cheung’s Example for Economists

Published: November 2017

We are delighted to be present today to share in the celebration of Steven Cheung’s 80th birthday. We bring best wishes from several others who could not be here – Yoram Barzel, Chris Hall, and Douglass North. Congratulations to Steve and thanks to Linda for this special occasion. Steve, congratulations on your keen observation, your broad experience, and the impact of your ideas. Our subject today is Steven Cheung’s advice to economists: that personal observation and real-world business experience can lead economists to greater insights and fewer errors. In his own words: “The world is my laboratory and I want to see things with my own eyes.” We certainly could use better economics. Is Steve right? And if he is right, how to implement his advice?
Workplace Democracy and Democratic Worker Organizations: Notes on Worker Centers
Authors: Fisk Catherine L.
Published: November 2017

Worker organizing outside the traditional union framework in the United States has lately focused on worker centers, which provide the benefits of collective action and participatory workplace democracy without the legal obstacles faced by unions. This Article offers thoughts on legal regulation of worker organizations’ internal governance to facilitate collective power with appropriate protection for the rights of individuals within the collective. Federal law extensively regulates the internal governance of unions so as to protect minorities in an organization that is an exclusive representative. It does not apply to worker centers, which disclaim the desire to represent workers for bargaining. Worker centers are regulated only lightly, under state law of nonprofit organizations. But if they become powerful, they will be large and will need to be managed by a leadership that may or may not remain accountable to the membership and respectful of minority rights. This Article offers a reading of the literature on union democracy from the 1950s as notes toward thinking about governance of worker organizations that are not labor unions.
Trade Union Ambivalence Toward Enforcement of Employment Standards as an Organizing Strategy
Authors: Landau Ingrid , Howe John
Published: November 2017

Trade unions in Australia have long played an important role in the enforcement of minimum employment standards. The legislative framework today continues to recognize this enforcement role, but in a way that is more individualistic and legalistic than in the past. At the same time that the law has evolved to emphasize the representation and servicing role of trade unions, the Australian union movement has sought to revitalize and grow through the adoption of an “organizing model” of unionism that emphasizes workplace-level activism. This Article explores how these seemingly opposing trends have manifested themselves in the enforcement-related activities of five trade unions. Considerable diversity was found among the unions in relation to the extent to which and how the unions performed enforcement-related activities. However, all five unions spent significant time and resources on monitoring and enforcing employer compliance with minimum standards and saw this work as a core part of what they do. The case studies suggest, however, that the way in which this work is undertaken within unions and by whom has changed significantly in recent decades. While there was evidence that enforcement work was used tactically by unions in certain cases, this was largely on an ad hoc basis and there was little indication that the enforcement work was integrated into broader organizing objectives and strategies. Overall, the unions were ambivalent, if not skeptical, as to the capacity for enforcement work to grow unions through building workplace activism and collective strength.
Informal Workers’ Aggregation and Law
Authors: Supriya Routh
Published: November 2017

In India, more than ninety percent of the workforce is informal. In spite of this enormous percentage of informal workers, these workers remain invisible to law and policy circles. One of the reasons for such exclusion and invisibility is the absence of unionism involving informal workers. In order to overcome this invisibility, informal workers are increasingly organizing into associations that are different from traditional trade unions. These organizations devise their strategies and their legal statuses in view of the atypical characteristics of informal activities. In this Article, I document some of these organizations of self-employed informal workers in India – their characteristics and functions. On this basis, I contend that these organizations offer a model for collective action by informal workers. I argue that these associations are a

Ward, PA, Ramsden, S, Coutts, AJ, Hulton, AT, and Drust, B. Positional differences in running and nonrunning activities during elite American football training. J Strength Cond Res XX(X): 000–000, 2017—The aim of this investigation was to describe differences in training loads between position groups within professional American football. Integrated micro technology data were collected on 63 NFL football players during an American football training camp. Five key metrics (total distance, high-speed distance, player load (PL), PL per minute, and total inertial movement analysis [IMA]) served to quantify both running and nonrunning activities. Players were classified into position groups (defensive back [DB], defensive linemen [DL], linebacker, offensive linemen [OL], quarterback, running back, tight end, and wide receiver [WR]). Training sessions were identified by their relationship to the upcoming match (e.g., -4, -3, and -2). Running and nonrunning activities varied between position groups relative to the training day. Differences in total distance between DB and WR were observed to be unclear across the 3 training days (game day [GD] -4: 74 ± 392 m; GD -3: −122 ± 348 m; and GD -2: −222 ± 371 m). However, moderate to large differences were observed between these 2 positions and the other positional groups. A similar relationship was observed in PL and PL per minute, with the DB and WR groups performing greater amounts of load compared with other positional groups. Differences in high-speed distance varied across positional groups, indicating different outputs based on ergonomic demands. The OL and DL groups ran less but engaged in a higher amount of nonrunning activities (total IMA) with differences ranging from moderate to large across the 3 training days. Total IMA differences between offensive and defensive linemen were unclear on GD -4 (−4 ± 9) and GD -2 (−2 ± 8) and likely moderate on GD -3 (−9 ± 9). Positional differences with regard to running and nonrunning activities highlight the existence of position-specific training within a training microcycle. In addition, total IMA provides a useful metric for quantifying sport-specific movements within the game of American football.
Electrophysiology Reveals the Neural Dynamics of Naturalistic Auditory Language Processing: Event-Related Potentials Reflect Continuous Model Updates
Authors: Alday Phillip M. , Schlesewsky Matthias , Bornkessel-Schlesewsky Ina
Published: November 2017

The recent trend away from ANOVA-based analyses places experimental investigations into the neurobiology of cognition in more naturalistic and ecologically valid designs within reach. Using mixed-effects models for epoch-based regression, we demonstrate the feasibility of examining event-related potentials (ERPs), and in particular the N400, to study the neural dynamics of human auditory language processing in a naturalistic setting. Despite the large variability between trials during naturalistic stimulation, we replicated previous findings from the literature: the effects of frequency, animacy, and word order and find previously unexplored interaction effects. This suggests a new perspective on ERPs, namely, as a continuous modulation reflecting continuous stimulation instead of a series of discrete and essentially sequential processes locked to discrete events.
Blackness and Televisual Reparations
Authors: Monk-Payton Brandy
Published: November 2017

The television screen has increasingly come to serve as a complex threshold for images of blackness across genres. What could be termed “televisual reparations,” therefore, emphasizes the medium's attempts to address the paradox of black “unfreedom” and provide redress for continuing race-related grievances, especially those connected to histories of violence. Such televisual acts of reparation occur at the levels of television industry, text, and audience. The industry maintains a tenuous commitment to provide opportunities for African American producers, writers, directors, and actors to the degree that such practice continues to be helpful to the reputation of the medium as well as profitable. The programming created often comments on civil rights by mobilizing references to the past of racial injustice in a variety of imaginative ways. Reparations, in this way, underscore how blackness comes to be televisually transmitted to audiences through the realm of spirits—spirits that come to resonate with viewers and call forth engagement with, and response to, representations of black mortality in the afterlife of slavery.
On Platforms
Authors: Benson-Allott Caetlin
Published: November 2017

Women-led serials have been getting a lot of attention lately for bringing “the female gaze” to the small screen. Jill Soloway—the television auteur behind Transparent (Amazon, 2014–) and the recent adaptation of Kraus's novel, I Love Dick (Amazon, 2017–)—even taught a class on “The Female Gaze” at the Toronto International Film Festival in 2016, defining it as “an intersectional gaze” and “a SOCIOPOLITICAL justice-demanding way of art making.”

But the female gaze is actually a very vexed concept. Since it was first invoked via exclusion in Laura Mulvey's foundational “Visual Pleasure and Narrative Cinema” in 1975, it has been haphazardly defined more often by what it is not than by what it is.

Three current series—I Love Dick, GLOW, and Insecure—all explore how women empower themselves through experiences of abjection: states of vexation and alienation that disrupt their expectations of or participation in social life. All three shows demand respect for their characters by figuring defeat, failure, and desperation as stages women must pass through to challenge patriarchal cultures. While all three shows feature diverse casts and strong female leads, I Love Dick and GLOW introduce characters of color only in supporting roles that contest but never destabilize the white protagonists' racial solipsism. This strategic but facile gesture reveals how far these shows have to go to confront the entangled injustices of social inequality. To incorporate the experiences and insights of women of color meaningfully, their creators would have to abandon the narrative commitments and familiar pleasures of white feminist television, which still needs to decenter whiteness both narratively and figuratively. Insecure's trenchant comedy thus provides a model for future feminist television. Its self-critical but antiracist humor challenges white feminism's and television's historic neglect of black women.

Published: November 2017

This special dossier for Film Quarterly comprises a selection of essays that share the central idea that the work ahead for scholars in the current moment must be to appreciate what has been an ever-increasing complication of the idea of black film and media over the last ten years. This dossier considers significant trends, film and media objects, and clusters of work related to issues of blackness and questions of aesthetics, historiography, industrial practice, collectivity, politics, and culture. It is compelled by a shared belief that requires scholars to remain open to contemporary and future enactments while at the same time recognizing the momentum of the past.

Published: November 2017

Archaeologists, historians, and art historians are increasingly turning to three-dimensional computer modeling to create dynamic visualizations of ancient monuments and urban spaces, but the resulting 3-D content is not always accepted as scholarship and integrated into discipline-specific dialogue. In Digital Karnak: An Experiment in Publication and Peer Review of Interactive, Three-Dimensional Content, Elaine A. Sullivan and Lisa M. Snyder propose a reconceptualization of computer modeling as a new means and form of knowledge production, offer a framework for peer review and publication of 3-D content, and describe an experiment to develop an innovative publication with an interactive computer model at its core. The Digital Karnak model, a geotemporal model of an ancient Egyptian temple, is their case study, a 3-D publication package of which they posted for peer review. This article describes the model's creation, the software interface used for the publication prototype (VSim), and the ways in which this project addresses the challenges of publishing 3-D scholarly content.

Published: November 2017

Aim. To analyze and predict the climate change impact on the crop structure, yield and gross collections of grain crops in short-term (2025), mid-term (2050) and long-term perspective. Methods. Analysis of long-term series of climatic parameters based on satellite data, climatic modeling, statistical analysis of crop yield and gross collection of grain crops. Results. The positive effect of historical and current climate change on grain crop yields in Ukraine is demonstrated. It is predicted that the preservation of this pattern and the implementation of an integrated system of measures for adapting agroecosystems to warming will promote further increase in the grain crop yield and thus its gross collection. Conclusions. According to the analysis of satellite data and climatic models, further climate warming is predicted and its positive impact on grain crop productivity is forecasted. In case of developing and implementing the measures to adapt agroecosystems to climate change, the grain yield in Ukraine may increase by 25 % in 2025 compared with the current period (2015) and by 29–30 % in 2050; the gross collection of grain crops will reach 75.0 million tons (in 2025) and 79.0–80.0 million tons (in 2050). On condition of effi cient material and technical, scientifi c and informational support, further development of technical means, the reproduction of soil fertility and the improvement of irrigation technologies in the long-term perspective (by 2100), the gross grain collection may reach 92–95 million tons.

Aim. Complex study on the physiological effect of citrate chelate nanoparticles of silver and copper on spring wheat plants under presowing soaking of seeds and foliar treatment of plants. Methods. Physiological, biochemical, bio- physical, microbiological, statistical. Results. The data on the physiological effect of the presowing soaking of seeds in the solutions of citrate chelate nanoparticles of silver and copper on growth processes and photochemical activity of leaves in laboratory conditions have been studied, analyzed, and summarized along with the effect of foliar treatment of spring wheat plants using the solutions of nanoparticles, and simulated phytoplasma (Acholeplasma laidlawii var. granulum st. 118) on the elements of the performance of spring wheat plants in fi eld conditions. It was demonstrated that there was a considerable stimulating effect of presowing soaking of wheat seeds in 0.5 % and 1 % solutions of nanocomposites on the growth of leaves and mass accumulation of 6–7-day old sprouts.
A considerable increase in the photochemical activity of the leaves of 7-day-old sprouts was found after presowing soaking in 0.5 % and 1 % solu- tions of nanocomposites which is in good agreement with the activation of growth processes. The negative effect of phytopathogens on the elements of grain productivity, fullness of grain in particular, was reduced in fi led conditions when wheat plants were infected and then treated with nanocomposites, though there was a weak phytotoxic effect of foliar treatment of intact plants with 1 % solution. Conclusions. A considerable stimulating physiological effect on the growth of leaves and mass accumulation of 6–7-day-old sprouts was established after the presowing soaking of spring wheat plants in 1 % and 0.5 % solutions of citrate chelate nanoparticles of silver and copper. The increase in photochemical activity was noted in the leaves of 7-day-old wheat plants in these conditions, namely, the increase in photochemistry effi ciency PSII, considerable decrease in
stationary fl uorescence and considerable – almost trip- le – increase in the value of induction coeffi cient Ki (correlating with the activity of ribulose biphosphate carboxylase (RuBPco)) which testifi es to the increase in the intensity of photosynthetic processes in the leaf apparatus of juvenile wheat plants. The fi eld experiment established that infecting wheat plants with phytoplasma (A. laidlawii) resulted in the reduction of the grain productivity indices: the weight of 1,000 grains and grain productivity in g/plant – by 14.6 and 35.5 % respectively, whereas treating with 1 % solution of silver and copper nanocomposites inhibited this process to some extent, promoting the increase in these parameters almost to the control level. The treatment of infected plants with nanoparticles led to a notable increase in the percentage of full grains. There was a weak phytotoxic effect after foliar treatment of intact wheat plants using nanocomposite solution.
Efficiency of using the new domestic meat-egg hybrid for the production of food eggs in household farms

Published: November 2017

Aim. A detailed analysis of the egg production and economic effi ciency of using a new dual-purpose hybrid in a comparative aspect with the original forms. Methods. Standard zootechnical methods of estimating body weight, egg production and its intensity, egg weight, feed costs and livability of adult hybrid and purebred hens were used. The effects of heterosis on the main utility indicators and the European profi t ratio IOFC (Income Over Feed Cost), which displays the difference between the revenue from one layer and the cost of consumed food, was estimated. Results. Almost all studied indicators demonstrated the advantage of the hybrid over the original forms. The phenomenon of heterosis was observed in most studied indices – 5.7 % by precocity, 3– 7 % by mass of eggs, 12–14 % by egg production. Early puberty (on 2–16 days), more intensive build-up of egg production (by 3.3–4.2 %), improvement of its medium intensity by 4.6–9.8 % provided by hybrid laying hens per year of life which were 9–20 eggs
superior than the origin forms. Due to the high productivity and low feed consumption per 10 eggs (2.1 kg versus 2.8 kg for the paternal form), the profi t ratio IOFC was also 28.7– 29.1 % higher for a hybrid. This indicates the expediency of using layers of a new hybrid combination for the production of food eggs in farming and household farms. Conclusions. The obtained zootechnical and eco- nomic indicators demonstrate the expediency of using layers of a new hybrid combination for the production of food eggs in farming and household farms.

Authors: El-Assaad Iqbal , Al-Kindi Sadeer G. , Aziz Peter F.
Published: November 2017

BACKGROUND AND OBJECTIVES:

Previous estimates of sudden cardiac death in children and young adults vary significantly, and population-based studies in the United States are lacking. We sought to estimate the incidence, causes, and mortality trends of sudden cardiac death in children and young adults (1–34 years).

METHODS:

Demographic and mortality data based on death certificates for US residents (1–34 years) were obtained (1999–2015). Cases of sudden death and sudden cardiac death were retrieved by using the International Classification of Diseases, 10th Revision codes.

RESULTS:

A total of 1 452 808 subjects aged 1 to 34 years died in the United States, of which 31 492 (2%) were due to sudden cardiac death. The estimated incidence of sudden cardiac death is 1.32 per 100 000 individuals and increased with age from 0.49 (1–10 years) to 2.76 (26–34 years). During the study period, incidence of sudden cardiac death declined from 1.48 to 1.13 per 100 000 (P < .001). Mortality reduction was observed across all racial and ethnic groups with a varying magnitude and was highest in children aged 11 to 18 years. Significant disparities were found, with non-Hispanic African American individuals and individuals aged 26 to 34 years having the highest mortality rates. The majority of young children (1–10 years) died of congenital heart disease (n = 1525, 46%), whereas young adults died most commonly from ischemic heart disease (n = 5075, 29%).

CONCLUSIONS:

Out-of-hospital sudden cardiac death rates declined 24% from 1999 to 2015. Disparities in mortality exist across age groups and racial and ethnic groups, with non-Hispanic African American individuals having the highest mortality rates.

The article presents the results of the study of histological changes in organs and tissues of dogs for coronavirus infection. The histological study of the pathological material of cadavers (n =5) dogs of different breeds and sex between the ages of 2 to 6 months, who died with diarrheal syndrome. The study of presence of coronavirus, without other assiociants, in these cases had previously been confirmed in the polymerase chain reaction analysis of fecal samples. The made histological sections were stained with hematoxylin and eosin according to standard prescriptions. The general histological structure and microstructural changes in histological preparations were studied under a light microscope. Histological studies have been confirmed and supplemented with pathoanatomical diagnoses, established after autopsies of dead bodies of dead animals. The most pronounced lesions and typical change in all dead dogs fixed contact in the small intestine (jejunum and to the ileum) and the regional lymph nodes to it, as well as in the spleen. It is shown that the morphological manifestations of coronavirus infection in dogs following features are on the microscopic level: the presence of exudative inflammation in the small intestine in the form serous-fibrinous jejuno-ileitis; hyperplasia of single and congested lymphoid nodes of the mucous membrane of the small intestine; hyperplasia and serous-hemorrhagic lymphadenitis mesenteric lymph nodes; foci of hemorrhage and hemorrhagic heart attacks in the spleen parenchyma; hyperplasia lymphoid nodes of the spleen; foci of hemorrhage in the serous membrane of the small intestine. Also, non-specific, but constant morphological features, which arose as a result of circulatory disorders and heart failure were: passive venous congestion of the liver and kidney; degenerative processes in the liver and kidney parenchyma. Consequently, local and general immunological processes develop during the coronaviral infection. Therefore, additional diagnostic markers appear hyperplastic and inflammatory changes of regional seats to the reproduction of the virus lymphoid organs.

Published: November 2017

Conducted a comprehensive comparative study of the nutritional and biological value Galega orientalis (Lam): the solubility of the protein in vitro – Galega’s seeds, leaves, hay, which was harvested in the phase of budding – beginning of flowering. It is believed to be the essential influence of feed type on the solubility of the protein. According to the conducted studies it has revealed that the solubility of the feed protein is in the range from 37.0% to 50.0%. The rate of solubility of Galega orientalis (Lam) seed protein is 50.0%, litestock – 40.0%, and hay – 37.0% from its total. The research results indicate that the protein of Galega orientalis (Lam) refers to the feed with the average level of solubility. It has researched qualitative assessment of the biologically active substances content in organs of Galega orientalis’ (Lam) plants. It has identified the highest content of flavonoids and saponins in rosette leaves and ascorbic acid in the organs of plants and petals. There is the high content of tannins found in the petals of Galega orientalis (Lam). There is a high content of coumarins and water-soluble polysaccharides in the roots of the studied plants. Phytochemical studies of the plant Galega orientalis (Lam) indicates the absence in it of cardiac glycosides and antrahlikozydiv. It was first conducted testing on antimicrobial activity of a plant Galega orientalis (Lam) on the growth pure cultural of bacteria gram positive (Micrococcus luteus), gram negative (Escherichia coli XL1, DH5) and yeasts (Saccharomyces cerevisiae W303). The material for the study was dried vegetative mass Galega orientalis (Lam) in the phase of budding and early flowering. As a result of the experiment was revealed that 20% concentration of aqueous extract of this plant had inhibitory effects on the growth of pure cultures of bacteria and yeast. It has grounded reasonably possible relationship between the antimicrobial activity of the extract of this plant and the lack of bloating in cows. It has outlined prospects of further researches of this problem.
Підбір умов для препаративного електрофорезу протеїнів сироватки молока у нативних умовах
Authors: Yukalo V.G. , Datsyshyn K.Ye.
Published: November 2017

Протеїни сироватки молока є попередниками більше сотні біоактивних пептидів. Ці пептиди можуть утворюватися в процесі травлення у шлунково-кишковому тракті, а також за дії протеаз молочнокислих бактерій і молокозгортальних препаратів. Серед них знайдено інгібітори ангіотензин-перетворювального ензиму, пептиди з опіоїдною та бактерицидною дією, імуномодуляторні та гіпохолестеролемічні пептиди, пептиди, які впливають на моторику кишечника, апетит та інші. Біоактивні пептиди з протеїнів сироватки молока становлять значний інтерес для створення функціональних продуктів або продуктів з профілактичними властивостями.  Створення таких продуктів передбачає  виділення біоактивних пептидів певної біологічної дії. Враховуючи специфіку їх розміщення у первинній структурі доцільним є використання для їх отримання гомогенних протеїнів-попередників з сироватки молока. Одним з методів для одностадійного розділення протеїнів сироватки молока є диск-електрофорез в нативній системі ПААГ для лужних і нейтральних протеїнів. Метою даної роботи було встановити параметри препаративного варіанту диск-електрофорезу для виділення гомогенних протеїнів сироватки молока. Дослідження проводили на модифікованому апараті Стадієра. Протеїни сироватки молока виділяли осадженням  казеїнів в ізоелектричній точці. Осад казеїнів відділяли центрифугуванням. Для ідентифікації протеїнів сироватки молока використовували гомогенні фракції α–лактальбуміну(α-LA) і β-лактоглобуліну(β-LG), які отримували шляхом повторної гель-фільтрації на сефадексі G-100(fine). Гомогенність і фракційний склад протеїнів сироватки молока визначали аналітичним  диск-електрофорезом у пластинах поліакриламідного гелю. Концентрацію протеїнів у зразках визначали спектрофотометрично (спектрофотометр СФ-46) при довжині хвилі λ = 280 нм.

Отримані результати доводять доцільність використання пластинок ПААГ для  препаративного фракціонування протеїнів сироватки молока. Встановлено допустиму тривалість і умови ідентифікації протеїнових фракцій. Показано, що вихід протеїнів у складі гомогенних фракцій становить 69,2%. При цьому співвідношення між кількістю отриманих фракцій (β-LG, α-LA, BSA і  ІG) близьке до їх розподілу у сироватці молока.

В останні роки на світовому ринку нових технологій харчових продуктів визначилася тенденція до збільшення кількості якісно нових продуктів, які призначені для запобігання різних захворювань, зміцнення захисних сил організму, зниження ризику впливу токсичних сполук і сприятливої екологічної дії. В ринкових умовах харчова промисловість динамічно розвивається за рахунок впровадження нових інтенсивних технологій і випуску на їх основі харчових продуктів оздоровчого та профілактичного напрямку, що забезпечує умови підвищення стану здоров'я населення і створює можливість конкурентноздатного виходу на міжнародний ринок. Тому, використовуючи останні досягнення науки і техніки, створюються нові кисломолочні напої із високими харчовими, дієтичними та лікувально-профілактичними властивостями. Разом з тим, функціональними можуть вважатися тільки ті продукти, які, крім своєї енергетичної цінності, володіють ще й здатністю здійснювати оздоровчий вплив на організм людини. Саме тому об’єктом наших досліджень було вибрано кефір з масовою часткою жиру 2,5%, який містить пшеничні висівки.

В результаті проведених експериментів було встановлено оптимальну дозу пшеничних висівок, яку доцільно вносити в кефір. Здійснено порівняльну характеристику кефіру традиційного і з пшеничними висівками протягом терміну зберігання на основі зміни фізико-хімічних та органолептичних показників. Встановлено, що кефір із пшеничними висівками є лікувально-профілактичним продуктом і може виготовлятися на підприємствах молочної галузі.

В статті розглядається процес фільтрування, який є одним з енергозатратних в переробній промисловості. Проаналізовано фактори що впливають на швидкість фільтрування. Процес фільтрування доцільно розглядати з врахуванням сил поверхневого натягу на межі контакту тверде тіло-рідина і для визначення швидкості фільтрування використовувати рівняння, які б враховували дію цих сил. Запропоновано для зменшення опору осаду на фільтрувальній перегородці та  інтенсифікації процесу фільтрування використовувати оптимальні концентрації різного роду поверхнево-активних речовин (ПАР). Експериментально знайдено оптимальну концентрацію аніонної ПАР до води, за якою коефіцієнт поверхневого натягу води є мінімальним. Показано, що за додавання оптимальної концентрації досліджуваної ПАР швидкість фільтрування у воді за температури 20 °С буде більшою у 2,3 рази ніж за нагрівання до температури 50 °С. Теоретично розраховані швидкості фільтрування у воді без ПАР та за додавання оптимальної концентрації аніонної ПАР.

На стенді гідромеханічних процесів проведена серія експериментів  для визначення швидкості фільтрування у воді без ПАР та за додавання оптимальної концентрації досліджуваної аніонної ПАР. Експериментальні дослідження добре узгоджуються з теоретичними розрахунками. Показано, що позитивна дія ПАР максимально проявляється тоді, коли частинки осаду починають відігравати функцію фільтрувальної перегородки. За таких умов  швидкість  фільтрування зростає у 2,5 рази.

Проблеми захисту і корекції дизрегуляції організму і його основних систем при радіаційному навантаженні може бути ефективно вирішені шляхом введення в організм дієтичних харчових добавок з біологічною активністю та функціональних продуктів харчування. У радіозахисному харчуванні важливе значення відводиться флавоноїдам. Метою досліджень було проведення аналізу основних рослинних джерел біофлавоноїдів та розробка харчової композиції для продуктів лікувально-профілактичного призначення, зокрема йогуртів.

Для приготування фітокомпозиції обрано ягоди шипшини, аронії та смородини чорної. Фітокомпозиції вносили у вигляді пюре. Для подовження терміну зберігання та використання композиції у зимовий період її пастеризують 25 хв. при температурі 85 °С. Кількісне співвідношення у пюре ягід смородини, аронії та шипшини становить 3:4:3.

Йогурт виготовляли термостатним способом. Для заквашування використовували закваску АВY-3 компанії Chr.Hansen, до складу якої входять такі види культур мікроорганізмів як Bifidobacterium species, Streptococcus thermophilus, Lactobacillus acidophilus,Lactobacillus delbrueckii subsp. bulgaricus.

Розроблено рецептури кисломолочних напоїв із використанням харчової композиції. Масова частка жиру у готовому продукті становить 2,5%. Досліджено основні фізико-хімічні показники готових продуктів. Встановлено, що збільшення сухих речовин суміші сприяє зростанню кількості міжмолекулярних просторових зв'язків між частинками казеїну, що призводить до інтенсивнішої їх взаємодії. Унаслідок цього помітно збільшується в'язкість продукту і знижується ступінь синерезису під час зберігання.  

Запропонована технологія йогурту з наповнювачами радіозахисної дії дозволяє розширити асортимент продукції з радіозахисними властивостями та забезпечити населення України, зокрема працівників зони відчуження та осіб, які проживають на екологічно забрудненій території, оздоровчими продуктами харчування.

У статі розглянуто регіональні особливості формування комплексу маркетингу сільського зеленого туризму в умовах економічної нестабільності. Метою дослідження є розвиток теоретичних і методичних підходів до формування комплексу маркетингу туристичних підприємств сільського зеленого туризму у Вінницькому регіоні. Обґрунтовані теоретико –  методологічні положення, науково-практичні рекомендації щодо просування послуг сільського зеленого туризму. Проаналізовано стан розвитку маркетингу сільського зеленого туризму в умовах розвитку ринкової економіки. Вказано на те, що сільський зелений туризм слід розглядати як невід’ємну складову програми комплексного соціально-економічного розвитку села та його відродження, а також, що за рахунок розвитку сільського зеленого туризму можна забезпечити сталий економічний, демографічний розвиток на селі. Показано просування туристичного продукту з використанням маркетингових заходів, які отримали назву «Сім Р». Вказані основні перешкоди власників агрооселі самотужки здійснювати маркетингові заходи із просування свого продукту на ринок. Показано, що маркетингова цінова політика продукту агрооселі на ринку ґрунтуються на основі трьох факторів: витрати, попит, конкуренція. В сучасних ринкових умовах лідером є цінова стратегія, яка базується на попиті: близько 54,2% менеджерів з маркетингу вважають її пріоритетною. Лише близько 15% туристичних підприємств області основним критерієм маркетингової цінової стратегії визначають конкуренцію. Ціни надавачі послуг сільського зеленого туризму публічно не розголошують, а посилаються на договірну ціну. Для подальшого розвитку сільського зеленого туризму в області розглянуто стратегією збалансованого регіонального розвитку Вінницької області на період до 2020 року. З’ясовано перелік проблемних питань, які перешкоджають розвитку сільського туризму, розв’язання яких вимагає спеціального нормативно-правового регулювання. Запропоновано сформулювати чітку маркетингову Стратегію управління розвитком туристичної галузі України на національному рівні, яка має узгоджуватися зі стратегіями та програмами розвитку туризму на регіональному рівні, що дасть можливість створити нові робочі місця, довести якість надання послуг і поступово поліпшити якість інфраструктурних складових (автомобільні дороги, агрооселі, музеї тощо), що забезпечуть комфортність споживання туристичних послуг іноземними та внутрішніми туристами.

In the article there are studied peculiarities of aloe extract application in the cultivation technology of herpes viruses on the re-cultivating culture of testicular piglets cells. We were faced with the following tasks: to select  a cell culture and aloe extract  concentration  to determine the toxic dose of the drug; to study the manifestation of the cytopathic effect in cell cultures infected with herpesvirus at different drug concentrations ; to determine  infectious virus activity after  its passage on the cells culture with the use of aloe extract. The work was carried out at the faculty of veterinary medicine, in the educational-research laboratory of epizootology department of microbiology, pharmacology and epizootology of the Zhytomyr National Agroecological University. The research materials included: the re-cultivating culture of testicular piglets, horse herpes virus of the first type and sterile aloe extract. Cultivation of crops, infection with the virus and determination of its concentration after contact with culture and the introduction of aloe extract were carried out under sterile conditions according to the generally accepted methods. The results were recorded daily, paying attention to the environment color changing, the integrity of the monolayer and the presence of cells in the medium. Along with the infected cells we were observing additional, uninfected, cultures of cells. The Incubation process was stopped at the destruction of 90-100% cell monolayer. As a result of this work, it is proved that the aloe extract in a dose of 0.14-0.28 mg per cm³ of growth medium allows to observe  for the 2nd day of replanting  a solid dense monolayer in the mattress without color changing , as well as enhanced growth and regeneration of cells and the metabolism of the epithelial tissue of the re-cultivating culture of testicular piglets, which makes it possible to shorten the time to grow a new monolayer for further virological and immunological studies. The use of this drug helps to increase cells concentration in the mattresses, which, in turn, can increase the concentration of the virus to 1-2 log2 for the use of similar amounts of growth medium without aloe extract. Such modified way to increase the biomass of cells is suitable for the further multiplication of viruses and the production of diagnostic antigens with lower economic costs. The use of this methodical approach will allow to solve a number of tasks related with accumulation of viruses and the production of drugs for the diagnosis and prevention of viral infections.

The article deals with the method of preparation of the liniment, the type of oil solution, based on thio-derivative of triazole. In order to determine the degree of the solution of the investigating substance in the Saint-Marry-thistle (silybum marianum) oil, other physical properties (capacity to stratification, hydrophilicity) and antimicrobial, antifungal action, the medical forms of the concentration at 1, 3, 5, 7, 10, 12, 15% were made. For the preparation of non-lethal oil solution,it was used the classical technology with the loading of the solvent in the order of increasing viscosity or density. The active substance weighed on the analytical scales (PCR-246) was put in dry bottles and was filled with the calculated mass of the thistle oil. To provide faster dissolution of the chemical compound in the oil, the vial was heated in a water bath (40–50 °C). It has been established that the new-synthesized compound is well soluble in thistle oil in the forms at 1, 3, 5 and 7%. The obtained solutions were marked by transparency, lack of sediment in the haze. The critical limit of solubility was 10% solution. For moderate solubility and light clouding, such crystallization was typical for such solutions, which disappeared in 10–15 minutes on the condition of heating it in a water bath  18–20 °C). At higher concentrations (12 and 15%) the investigated chemical compound was littlesoluble and insoluble, precipitated (felt out in sediment) and crystallized. The concentration of the solution (1, 3, 5 and 7%) was characterized by resistance to bundle. For 10% solutions of the investigating dosage form, there was a slight stratification with signs of crystallization on the verge. Sorbent capacity of oil solutions is insignificant and stops after 2 hours. According to the assessment of the effect of the new- developed therapeutic agent on microorganisms and fungi, a deleterious effect on S. aureus and C. albicans and A. niger was noted, which provides the basis for preclinical studies on laboratory animals, especially with the patterns of solution at 7 and 10%  concentration.
