Authors: Wu Ji-Hua , Deng Yao-Liang , Liu Quan , Yu Jun-Chuan , Liu Yun-Long , He Zi-Qi , Guan Xiao-Feng
Published: June 2017

Calcifying nanoparticles have been linked to various types of human disease, but how they contribute to disease processes is unclear. Here, we examined whether and how calcifying nanoparticles isolated from patients with kidney stones are cytotoxic to human bladder cancer cells. Calcifying nanoparticles were isolated from midstream urine of patients with renal calcium oxalate stones and examined by electron microscopy. Human bladder cancer cells (EJ cells) were cultured in the presence of calcifying nanoparticles or nanohydroxyapatites for 12 and 72 h and examined for toxicity using the Cell Counting Kit-8, for autophagy using transmission electron microscopy and confocal microscopy, and for apoptosis using fluorescence microscopy, transmission electron microscopy, and flow cytometry. Changes in protein expression were analyzed by Western blotting. The results showed that the size and shape of the isolated calcifying nanoparticles were as expected. Calcifying nanoparticles were cytotoxic to EJ cells, more so than nanohydroxyapatites, and this was due, at least in part, to the production of intracellular reactive oxygen species. Transmission electron microscopy showed that calcifying nanoparticles were packaged into vesicles and autolysosomes. Calcifying nanoparticles induced greater autophagy and apoptosis than nanohydroxyapatites. Our findings demonstrate that calcifying nanoparticles can trigger bladder cancer cell injury by boosting reactive oxygen species production and stimulating autophagy and apoptosis.
Group work and the change of obstacles over time: The influence of learning style and group composition
Authors: Soetanto Danny , MacDonald Matthew
Published: June 2017

It is through working in groups that students develop cooperative learning skills and experience. However, group work activity often leads students into a difficult experience, especially for first-year students who are not familiar with group work activities at university. This study explores obstacles faced by first-year students during their group work activities. It investigates whether a group of students with a similar learning style (homogeneous group) experience different obstacles compared to a group of students with a diverse learning style (heterogeneous group). In addition, to identify the difference, if any, between a group formed by a tutor and one where the students form the group themselves, tutor and self-allocated group allocations are explored. This study focuses on obstacles experienced by these students during group work activities. Using a sample of more than 200 students over a period of 3 years, the types and the changes of obstacles in different stages of group life are explored. The findings show that students experience obstacles which can be classified into personal and social, leadership and management, and task-related obstacles. Those obstacles were not static but increased over time. The study also investigates the impact of different methods of forming groups and whether this impacted on obstacles experienced. Overall, different interventions prompted different patterns of obstacle development.
Towards a rhythmanalysis of debt dressage: Education as rhythmic resistance in everyday indebted life
Authors: Wozniak Jason Thomas
Published: June 2017

Debt shapes subjectivity by rhythmically training indebted subjects. Stated slightly differently, there exists a debt dressage that produces indebted subjectivity. One of the principle aims of this article is to introduce rhythm into the debt analysis debates. Building on Henri Lefebvre’s book Rhythmanalysis: Space, Time and Everyday Life, this article attempts to theoretically justify, as well as engage in, a rhythmanalysis of indebted life. The article concludes with the claim that education experience can be made up of, and produce, rhythms that disrupt the production of indebted subjectivity.
Modeling of smart magnetically affected flexoelectric/piezoelectric nanostructures incorporating surface effects
Authors: Ebrahimi Farzad , Barati Mohammad Reza
Published: June 2017

In this article, electromechanical buckling behavior of size-dependent flexoelectric/piezoelectric nanobeams is investigated based on nonlocal and surface elasticity theories. Flexoelectricity represents the coupling between the strain gradients and electrical polarizations. Flexoelectric/piezoelectric nanostructures can tolerate higher buckling loads compared with conventional piezoelectric ones, especially at lower thicknesses. Nonlocal elasticity theory of Eringen is applied for analyzing flexoelectric/piezoelectric nanobeams for the first time. The flexoelectric/piezoelectric nanobeams are assumed to be in contact with a two-parameter elastic foundation which consists of infinite linear springs and a shear layer. The residual surface stresses which are usually neglected in modeling of flexoelectric nanobeams are incorporated into nonlocal elasticity to provide better understanding of the physics of the problem. Applying an analytical method which satisfies various boundary conditions, the governing equations obtained from Hamilton’s principle are solved. The reliability of the present approach is verified by comparing the obtained results with those provided in literature. Finally, the influences of nonlocal parameter, surface effects plate geometrical parameters, elastic foundation, and boundary conditions on the buckling characteristics of the flexoelectric/piezoelectric nanobeams are explored in detail.
The Quality of Sustainability Reports and Corporate Financial Performance: Evidence From Brazilian Listed Companies
Authors: Ching Hong Yuh , Gerab Fábio , Toste Thiago Henrique
Published: June 2017

Corporate sustainability is essential to long-term corporate success and for ensuring markets deliver value across society, and despite its importance, there is no clear consensus as to whether the financial performance of companies relates to their sustainability performance. The objectives of this study are to verify whether the sustainability reporting quality would affect corporate financial performance (CFP) among the firms listed on Corporate Sustainability Index (ISE) and to examine the quality of information disclosed in their sustainability reports (SR). The sample is composed of all firms listed on ISE for the period 2008 to 2014. This study considered accounting and market-based indicators and control variables. There is no clear consensus as to whether the financial performance of companies listed in sustainability indices relates to their sustainability performance. The main findings are as follows: There is no association between accounting and market-based variables and the reporting quality, and although the quality disclosure is improving throughout the years studied, the scores are still low. This is also true in the three dimensions of sustainability. We are not aware of studies examining the relationship between CFP and sustainability reporting quality, and this is the main contribution.
Social Networks in the Workplace in Postreform Urban China
Authors: Kwon Soyoung
Published: June 2017

Drawing upon organizational foci theory and market transition theory, this study examined social networks in the workplace in postreform urban China. Specifically, this study assessed the association between employment sector and employees’ social ties with coworkers and its differentials association by regions with varying levels of market economy development. Data from the Chinese General Social Survey 2003 were analyzed using negative binomial regressions. Results showed that state/collective sector workers reported more coworker ties than private sector workers, which was more prominent in less marketized regions. Moreover, sectoral differences in coworker ties were partially explained by highly constraining organizational foci embedded in the danwei system. These findings highlight the role market transition plays in restructuring social space and relations in urban China.

Perioperative Venous Thromboembolism: A Review
Authors: Gordon Ronald J. , Lombard Frederick W.
Published: June 2017

Venous thromboembolism (VTE) is a significant problem in the perioperative period, increasing patient morbidity, mortality, and health care costs. It is also considered the most preventable of the major postoperative complications. Despite widespread adoption of prophylaxis guidelines, it appears that morbidity from the disease has not substantially changed within the past 2 decades. It is becoming clear that current prophylaxis efforts are not sufficient. Using more potent anticoagulants may decrease the incidence of VTE, but increase the risk for bleeding and infection. Much has been learned about the pathophysiology of venous thrombogenesis in recent years. Beyond the “traditional coagulation cascade,” which anticoagulants modulate, there is a growing appreciation for the roles of tissue factor, monocytes, neutrophils, neutrophil extracellular traps, microvesicles, and platelets in thrombus initiation and propagation. These recent studies explain to some degree why aspirin appears to be remarkably effective in preventing thrombus propagation. Endothelial dysfunction, traditionally thought of as a risk factor for arterial thrombosis, plays an important role within the cusps of venous valves, a unique environment where the majority of venous thrombi originate. This suggests a role for newer treatment modalities such as statins. Not all patients have an equal likelihood of experiencing a VTE, even when undergoing high-risk procedures, and better tools are required to accurately predict VTE risk. Only then will we be able to effectively individualize prophylaxis by balancing the risks for VTE against the risks associated with treatment. Given the different cell types and pathways involved in thrombogenesis, it is likely that multimodal treatment regimens will be more effective, enabling the use of lower and safer doses of hemostatic modulating therapies such as anticoagulants, antithrombotics, and antiplatelet medications.
exampletestr—An easy start to unit testing R packages
Authors: Nolan Rory , Padilla-Parra Sergi
Published: June 2017

In spite of the utility of unit tests, most R package developers do not write them. exampletestr makes it easier to start writing unit tests by creating shells/skeletons of unit tests based on the examples in the user's package documentation. When completed, these unit tests test whether said examples run correctly. By combining the functionality of exampletestr with that of covr, having ensured that their examples adequately demonstrate the features of their package, the developer can have much of the work of constructing a comprehensive set of unit tests done for them.

Authors: Mkandawire Elina
Published: June 2017

In order to compare the environmental performance of the existing pest control methods used by Malawian smallholder farmers a study was conducted to assess the environmental performance of two pest control methods used in cultivation of tomatoes (traditional pest control method vs. modernized pest control method). The study was conducted in two gardens, a farm using traditional pest control methods (Tikondwe Freedom Gardens) and another farm using modernized pest control techniques (Mgwirizano Farm Produce Club). The soil and tomato samples were analyzed, by liquid chromatography–mass spectrometry (LC–MS) with electrospray ionization (ESI) in positive mode. The results revealed the presence of pesticide residues at various concentration levels both in the soil and tomato samples. The concentrations of pesticide residues regarding the Mgwirizano Farm Produce Club Gardens were; for tomatoes, Dimethoate (1.2 - 3 ppm), L-Cyhalothrin, (0.2-3 ppm) Cypermethrin (< 0.03 ppm) Mancozeb (2-4 ppm) Chlorothalonil (0.02- 3ppm) while for soil samples, Dimethoate (<0.01 ppm), L-Cyhalothrin (<0.01ppm), Cypermethrin (<0.01ppm), Mancozeb (0.3- 1ppm) and Chlorothalonil (0.02- 2ppm). For comparison purposes tomato and soil samples collected from the field that uses traditional pest control methods (Tikondwe freedom farm) were also analyzed for pesticides residues and had the following outcome, the tomatoes had Dimethoate (< 0.01 ppm), L-Cyhalothrin, (0.01 ppm) Cypermethrin (< 0.01 ppm) Mancozeb (<0.01ppm) Chlorothalonil (<0.01 ppm) while the soil samples had concentrations of Dimethoate (0.03 ppm), L-Cyhalothrin (<0.01ppm), Cypermethrin (0.02ppm), Mancozeb (0.01ppm) and Chlorothalonil (0.01ppm). Furthermore, the study collected more information on health effects of pest management methodologies through Interviews with farmers, farm workers and health practitioners in rural areas where horticultural crops such as tomatoes are mostly cultivated using farm inputs, particularly pesticides.

Detection and Isolation of Zombie Attack under Cloud Environment
Authors: Kumar Sunil , Singh Maninder
Published: June 2017

Network security, data security and several other security types such as the computer security collectively compose the word “Cloud Security”. Cloud computing posses a new challenge because traditional security mechanism is being followed are insufficient to safeguard the cloud resources. Cloud computing can easily be targeted by the attackers. A group of malicious users or illegitimate users can attack on system which may lead to denial the services of legitimate users. Such kinds of attacks are performed by the malicious (zombie) attackers. The zombie attack will degrade the network performance to large extend. Traditional techniques are not easily capable to detect the zombie attacker in the cloud network. So in this paper we have proposed a technique which is the enhancement of the mutual authentication scheme in order to detect and isolate zombie attack for the efficient performance of the network.

Electronic Dictionary and Machine Translation system are both the most important language learning tools to achieve the knowledge about the known and unknown natural languages. The natural languages are the most important aspect in human life for communication. Therefore, these two tools are very important and frequently used in human daily life. The Electronic Dictionary (E-dictionary) and Machine Translation (MT) systems are specially very helpful for students, research scholars, teachers, travellers and businessman. The E-dictionary and MT are very important applications and research tasks in Natural Language Processing (NLP). The demand of research task in E-dictionary and MT system are growing in the world as well as in India. North-East (NE) is a very popular and multilingual region of India. Even then, a small number of E-dictionary and MT system have been developed for NE languages. Through this paper, we want to elaborate about the importance, approaches and features of E-dictionary and MT system. This paper also tries to review about the existing E-dictionary and MT system which are developed for NE languages in NE India.
A look at ‘fishy drag’ and androgynous fashion: Exploring the border spaces beyond gender-normative deviance for the straight, cisgendered woman
Authors: Willson Jacki , McCartney Nicola
Published: June 2017

This article seeks to re-explore and critique the current trend of androgyny in fashion and popular culture and the potential it may hold for gender-deviant dress and politics. In order to do this, it will discuss the way in which a popular version of male drag has monopolized a vision of gender subversion that has marginalized ‘straight’ cisgendered women’s transgressive challenge to gender norms. Although not misogynistic in itself, RuPaul’s Drag Race (Logo 2009–2017) brings to the surface the misogyny inherent in femininity – the performance underscores deeper asymmetrical power imbalances which are embedded in women’s daily lives. Recent unisex fashion collections with their subsequent campaigns have sought to address this imbalance; however, this is not a problem with an easy fix. This article looks at the way in which particular performers such as Grace Jones and Harnaam Kaur have ad(dressed) their gender resistance without camouflaging and thus losing sight of a feminist history of gender inequality which still strongly resonates.

Uživanje alkohola med starostniki v domačem okolju: rezultati presejalnega testa SMAST-G
Authors: Kobentar Radojka , Kusić Zoran
Published: June 2017

Uvod: Dosedanje raziskave kažejo, da je tvegano ali škodljivo uživanje alkohola med starostniki prisotno v obsegu med 5 % in 23 % te populacije. Z raziskavo smo želeli preučiti pojavnost uživanja alkohola v starosti v povezavi z demografskimi dejavniki, socialno vključenostjo in samooceno zdravja. Metode: Uporabljen je bil standardizirani vprašalnik Short Michigan Alcoholism Screening Test – Geriatric version (SMAST-G). Nenaključno so bili vključeni starostniki nad 65 let, živeči v domačem okolju, ki so razumeli besedilo. Podatke smo obdelali z opisno statistiko in testom hi-kvadrat. Rezultati: Ugotovili smo, da je med starostniki 30,0 % takšnih, ki imajo možne težave z alkoholom. Statistična značilnost večjega uživanja alkohola se je pokazala pri nižji izobrazbi (x2 = 12,255, p = 0,007) ter pri moškem spolu (x2 = 14,641, p < 0,001). Ugotovili smo statistično povezanost uživanja alkohola s samooceno zdravja (x2 = 12,085, p = 0,017) ter s posameznimi spremenljivkami socialne vključenosti, in sicer z oceno socialnih odnosov (x2 = 14,124, p< 0,001) in z (ne)obstojem osebnih ciljev za prihodnost (x2 = 12,156, p = 0,016). Diskusija in zaključek: Uživanje alkohola se pri starostnikih povezuje s slabšo kakovostjo socialnih odnosov in nižjo samooceno zdravja. Raziskava kaže na potrebo po zvišanju znanja starostnikov o vplivih uživanja alkohola na zdravje, na potrebo po njihovi integraciji v socialno okolje ter po nadaljnjem raziskovanju problema uživanja alkohola v starosti.
Oxytocin for labour induction or augmentation as a risk factor for autism: systematic literature review
Authors: Grosek Marija , Lučovnik Miha
Published: June 2017

Introduction: Some studies have shown a potential association between oxytocin use during labour and autism spectrum disorder in children (ASD). We performed a systematic review of recent studies examining this association. Methods: Boolean operators (AND/OR) were used to search MEDLINE using the following search criteria: Autistic Disorder or Autism Spectrum Disorder or Autism and Labour Induction or Labour Augmentation. Articles published in English in 2013 or later were considered. Additional studies were identified by reviewing citations. Only studies conducted on people were included. Studies not accounting for potential confounding factors were excluded. Results: Four retrospective cohort studies met the inclusion criteria. One showed an association between labour induction and augmentation and ASD, one showed a weak association between labour augmentation in boys and ASD, and one showed no association between labour induction or augmentation and ASD. The largest study showed a weak association between labour induction and ASD, which was not significant when siblings were analyzed separately. Discussion and conclusions: Recently published studies do not support the hypothesis of a causal relationship between oxytocin use during labour and ASD. Benefits of medically indicated induction or augmentation of labour outweigh the theoretical risk of ASD.
Effect of different accellerators and inoculums used in fermentation on quality of dead chicken silage flour as feed ingredient for catfish
Authors: Bakrie B. , Sastro Y. , Sudolar N. R.
Published: June 2017

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

Modeling and simulation of membrane process
Authors: Staszak Maciej
Published: June 2017

The article presents the different approaches to polymer membrane mathematical modeling. Traditional models based on experimental physicochemical correlations and balance models are presented in the first part. Quantum and molecular mechanics models are presented as they are more popular for polymer membranes in fuel cells. The initial part is enclosed by neural network models which found their use for different types of processes in polymer membranes. The second part is devoted to models of fluid dynamics. The computational fluid dynamics technique can be divided into solving of Navier-Stokes equations and into Boltzmann lattice models. Both approaches are presented focusing on membrane processes.

“It is always now” (Beloved): Notes on the Urgency of Enslavism Theory, and Studies
Authors: Broeck Sabine
Published: June 2017

This article argues for the necessity, for white scholars, to turn to the study of what I call enslavism, a term necessary to situate current anti-Black practices in the “future that had been created by men and women in chains” (Hartman, Saidiya V. [2007]. Lose Your Mother: A Journey Along the Atlantic Slave Route. New York, NY: Farrar, 233) and thus to critique them as the ongoing afterlife of enslavement, instead of addressing slavery as an event in bygone history. Conceptualizing their work with this term, white scholars may labor to contribute to Black Studies by way of “sitting with” (see Sharpe, Christina [2016]. In the Wake: On Blackness and Being. Durham, NC: Duke University Press) black knowledge which can enable us to produce a critical protocol, to paraphrase Hortense Spillers, of enslavism as the ongoing afterlife of social, cultural and political anti-Blackness in the future that transatlantic enslavement has made. To produce those critical protocols means to re-read the longue durée of humanism in a way that abolishes the human’s ontological reign of life, and of knowledge, based as it has been on black non-existence for the human.
Vagrant Presences: Lost Children, the Black Atlantic, and Northern Britain
Authors: Rice Alan
Published: June 2017

This article discusses a range of African Atlantic figures whose vagrant and vagabond lifestyles help to broaden Paul Gilroy’s conception of the Black Atlantic. Geographically, the author moves away from metropolitan concerns to discuss the rural and the provincial as key areas to discover hidden truths about African Atlantic peoples. The article investigates North British historical concerns from slavery and its aftermath in Scotland to the Cotton Famine in Lancashire. It takes a close look at the radical Scots-descended Robert Wedderburn, the North-of-England-based circus performer Pablo Fanque and the fugitive slave and wanderer James Johnson. It also discusses contemporary artistic responses to black presence in North Britain by Ingrid Pollard and Jade Montserrat to show how these presences are being remembered and reimagined. It uses the theoretical model of multi-dimensional memory, developed by Michael Rothberg, to investigate the way these historical characters and events are key to the fullest understanding of the Black Atlantic in Britain and beyond.

Este artigo apresenta uma análise acústica e sociolinguística das vogais médiaspretônicas de Montanha, cidade do extremo-norte do Espírito Santo. Para isso, selecionamos 4 informantes, dois homens e duas mulheres, de duas faixas etárias (18-30 e 31-50 anos). O corpus foi obtido pela apresentação de figuras inseridas na frase-veículo “Digo ______ baixinho”, repetidas cinco vezes por falante. Através do plug-in Akustyk, no programa Praat, extraímos os valores do primeiro e segundo formantes das vogais estudadas. Como resultado,observamos que as vogais médias-baixas de Montanha são mais baixas se comparadas às do Rio de Janeiro, Salvador e Vitória. Em relação à anterioridade/posterioridade, Montanha apresentou vogais anteriores bem mais anteriorizadas e posteriores bem mais posteriorizadas do que a das outras cidades. Quanto à análise sociolinguística, a variável faixa etária foi selecionada, pelo programa GoldVarb X, como a mais significativa na manutenção da vogal média-alta em posição pretônica, sendo a faixa de 18 a 30 anos a maior responsável pela manutenção.********************************************************************Abstract: This article presents acoustic and sociolinguistic descriptions of pre-stressed mid vowels in Montanha, a city at the extreme north of Espírito Santo state.

The corpus was obtained from the presentation of figures inserted into the carrier sentence “Digo ______ baixinho” and repeated five times by speaker. Using the plug-in Akustyk within Praat, we extracted the values of the first and second formants of the vowels. As a result, we noticedthat the medium-high vowels of Montanha are lower compared to those of Rio de Janeiro, Salvador and Vitória. About anteriority/posteriority, Montanha presented anterior vowels much more anteriorized, and posterior vowels much more posteriorized, compared to the other cities. Regarding sociolinguistic analysis, the age variable was selected by GoldVarb X program as the most significant for maintaining the medium-high vowel in pre-stressed position, and the range of 18 to 30 was the most responsible for this maintenance.Keywords: Pre-stressed mid vowels; Linguistic variation; Acoustic analysis; Capixaba dialect
A identificação das variedades regionais do português brasileiro através da informação entoacional
Authors: Peres Daniel Oliveira
Published: June 2017

Este estudo tem como objetivo verificar se falantes do português brasileiro são capazes de reconhecer suas próprias variedades regionais a partir das informações entoacionais. Além disso, também pretende procurar pistas nas variações de F0 que possam justificar o desempenho dos participantes. Os dois experimentos realizados neste trabalho foram feitos com base em três variedades do Português Brasileiro: a variedade de Pelotas (RS), São Paulo (bairro da Mooca) e Senador Pompeu (CE). O experimento 1 foi desenvolvido com estímulos de fala delexicalizada, e.g., com apenas as informações entoacionais; o experimento 2 apresentou estímulos de fala sem variação de F0, e.g., apenas com a curva melódica monotônica. Os resultados obtidos através da Teoria de Detecção (MACMILLAN; CREELMAN, 2005) mostraram que os participantes tiveram um desempenho significativo. Os resultados obtidos nos dois experimentos foram diferentes, pois houve mais dificuldade de reconhecimento no experimento com estímulos delexicalizados. A tendência dos alarmes falsos também mostrou que a informação entoacional desempenha um papel importante no reconhecimento de variedades regionais.********************************************************************The identification of Brazilian Portuguese regional varieties through intonational informationThis study aims to verify if Brazilian Portuguese speakers are able to recognize their own regional varieties only by listening to the intonational information. It also aims to search for cues in F0 variation, which can justify the performance of the participants. The two experiments conducted in this study deal with three varieties of Brazilian Portuguese: the variety of Pelotas (RS), São Paulo (Mooca district) and Senador Pompeu (CE). Experiment 1 was developed with delexicalised speech stimuli, e.g., intonational information only; experiment 2 presented stimuli with a flat melodic curve only, e.g., with no F0 variations. The results based on the Detection Theory (MACMILLAN; CREELMAN, 2005) showed that the participants had a performance above chance. The results obtained in both experiments were different as we observed more recognition difficulties in the experiment with delexicalized stimuli. The tendency of false alarms also showed that intonational information plays an important role in the recognition of regional varieties.Keywords: Sociophonetics; Speech perception; Intonation; Brazilian Portuguese
Construyendo un imaginario externo de Costa Rica en el siglo XIX: el caso de Félix Belly
Authors: Soto-Quirós Ronald
Published: June 2017

El presente estudio intenta examinar la imagen de Costa Rica y de los costarricenses que se fue construyendo en el exterior durante el siglo XIX. Los estudios sobre la invención de una comunidad imaginada costarricense se han basado especialmente en fuentes propiamente costarricenses. Nuestra investigación va dirigida a identificar de manera más profunda las características de esta construcción histórica a través de un ejemplo preciso: las obras de la segunda mitad del siglo XIX escritas por el francés Félix Belly en el marco de promoción de un proyecto de canal interoceánico en Centroamérica. La caracterización de la comunidad política costarricense permite a Belly situar la viabilidad de un modelo político moderno republicano en la región hispanoamericana y de rechazar las tradicionales prácticas políticas de Europa.

Сепарирование семян относится к основным технологическим процессам послеуборочной обработки и выполняется с целью очистки, сортирования, калибрования, обогащения посевного материала. Известны различные способы сепарирования в зависимости от состояния и назначения семян. Основным способом является просеивание семенных смесей на ситах зерносепараторов в различных режимах. Аэродинамическое проводится в воздушном потоке и применяется, в основном, для очистки и отделения легких примесей. В последнее время созданы аэродинамические сепараторы, которые предлагаются не только для очистки, но и сортирования. Однако, не известно влияние этого способа сепарирования на выход и качество семян отдельных фракций. Целью работы было установить влияние аэродинамического сепарирования в процессе сортирования-калибрования однокомпонентных семенных смесей.Исследования проводили на примере гибридов кукурузы, для которых сортирование-калибрование значительно определяет выход и качество продукции. Изучали гибриды селекции Института – Ушицкий 167 СВ, Пятихатский 270 СВ, Борозенский 277 МВ, Солонянский 298 СВ, Збруч. Для изучения качества применяли методы ДСТУ 4138, а также разработанные в Институте для семян кукурузы. Однокомпонентную смесь получали после очистки семян в виде посевной группы сходом и проходом с основного сита в зависимости от гибридов.Установлено особенности аэродинамического сепарирования в процессе обработки семян, для которых проведена очистка и сформирована посевная группа. Выявлена нестабильность сепарирования в связи с изменением в воздушном потоке показателей парусности семенной смеси в зависимости от ее места и положения, а также скорости и плотности воздуха. Семена гибридов в воздушном потоке распределялись под влиянием формы, размера, объема, массы 1000 семян и гораздо меньше — от показателей удельной поверхности и массы (плотности). В связи с этим, аэродинамическое сепарирование рекомендовано применять на первичном этапе для очистки семян, а на вторичном – для сортированиякалибрования более глубокое ситовое и гравитационное сепарирование на соответствующих машинах. На основании полученных данных разработана вариационная кривая аэродинамического распределения однокомпонентной смеси семян.

У статті розглянута загальна ситуація розвитку конярства в Україні та проблеми зниження динаміки поголів’я коней. Також розглянуто розподіл поголів'я коней по господарствам різних форм власності та структура виробництва комбікормів для сільськогосподарських тварин, у тому числі для коней.Зроблено аналіз виробництва яблук в Україні, з якого видно тенденцію зростання виробництва. Переробка яблук полягає в отриманні основної продукції, а також в отриманні побічної продукції.Розглянута можливість використання яблучних вичавків як компонента комбікормів. У лабораторних умовах досліджені фізичні властивості, хімічний склад та мікробіологічні показники свіжих яблучних вичавків. Яблучні вичавки багаті безазотистими екстрактивними речовинами, а також незамінними амінокислотами, вітамінами і мінеральними елементами. Яблучні вичавки не стійкі при зберіганні та швидко псуються, тому досліджено динаміку мікрофлори та терміни зберігання свіжих яблучних вичавків.Обґрунтовано вибір зерна ячменю для виробництва кормової добавки. Наведена поетапна схема виробництва кормової добавки шляхом екструдування суміші подрібненого зерна ячменю та подрібнених яблучних вичавків. На основі експериментальних досліджень обґрунтовано співвідношення компонентів екструдованої кормової добавки (ЕКД). Для визначення оптимального співвідношення компонентів ЕКД досліджено вплив введення яблучних вичавків на ефективність процесу екструдування за якісними та енергосиловими показниками, а саме за коефіцієнтом розширення екструдату та питомими витратами електроенергії. Досліджено вплив екструдування на зміну фізичних властивостей ЕКД. Також досліджено зміни хімічного складу ЕКД. У зразках кормової добавки визначали ступінь набухання, яка характеризує ефективність засвоєння поживних речовин організмом тварин.Досліджено вплив екструдування на зміну кількісного і якісного складу мікрофлори в зерні ячменю, свіжих яблучних вичавок і кормової добавки до і після екструдування. Також досліджено динаміку розвитку мікрофлори ЕКД протягом 6 місяців зберігання у нерегульованих умовах.

В матеріалах статі на основі потреб домашніх тварин (собак) в поживних і біологічно-активних речовинах (БАР) науково обґрунтовано вибір кормової сировини для виробництва білково-вітамінно-мінеральної добавки (БВМД). Наведено характеристику отриманої БВМД для домашніх тварин (собак), яку розроблено за науково-обгрунтованим рецептом та розрахованим за допомогою програми КормОптимаЭксперт, за органолептичними, фізичними та хімічними показниками якості. Розроблена БВМД для собак в залежності від рецепту може містити від 30 до 36 % сирого протеїну. Порівняльний аналіз показників якості БВМД для собак згідно вимог нормативно-технічної документації показав її відповідність ДСТУ 7111-2009.В статті представлені результати оцінки санітарної якості кормової сировини і готової продукції БВМД для домашніх тварин (собак) в процесі зберігання протягом чотирьох місяців в поліетиленовій упаковці в нерегульованих умовах при температурі + 10 – 15 оС і відносній вологості повітря 60…70 %. Всі дослідження з визначення мікробіоти кормової сировини проводили для компонентів, які найбільш піддаються мікробіальній порчі в процесі зберігання: мідійна мука, крилева мука, водорості, дріжджі кормові, калоген. Санітарний стан кормової сировини і готової БВМД для собак оцінювали за кількісним і якісним складом мікроорганізмів: мезофільними аеробними і факультативно-анаеробними мікроорганізмами (МАФАнМ), бактеріями групи кишкової полочки БГКП, умовно-патогенними (Escherihia coli i Staphylococcus aureus), патогенними мікроорганізмами (сальмонели, стафілокок, протей, сульфидредукуючі клостридії, плісеневі гриби і дріжджі), які визначали класичними методами шляхом висівання в поживні середовища з подальшим культивуванням і характеристикою посівів.В результатах дослідження представлена характеристика мікробіоти кормової сировини, яка входить до складу БВМД для собак. Слід зазначити, що в усіх досліджуваних видах сировини і БВМД кишкова паличка, сальмонели, стафілокок, протей, сульфідрекукуючі клостридії не виявлені. На підставі результатів дослідження кількісного і якісного складу мікробіоти кормової сировини і БВМД для собак встановлено, що показники загального числа (МАФАнМ) і показники коліформних мікроорганізмів (БГКП) знаходяться в дозволених межах протягом зберігання 90 діб. Розроблено рекомендації щодо використання і зберігання кормової сировини і БВМД для домашніх тварин.

Наявність інноваційної складової у концепції підприємства є однією із умов його сталої конкурентоспроможності. Інноваційний розвиток закладів ресторанного господарства (ЗРГ) та підприємств харчової промисловості є основою стратегічного планування, яке формує комплекс заходів, пов’язаних із випуском нового виду продукції, впровадженням і використанням нових технологій, розвитком ринків збуту, організацією виробництва. Тому сьогодні ЗРГ та харчова промисловість орієнтується на інноваційний шлях розвитку, в основі якого лежить цілеспрямований процес пошуку нових технологій та сировинних джерел, що характеризуються доступністю, технологічністю, функціональністю. Найважливішою умовою створення нової технології є отримання продукції, яка не поступається за якістю аналогам, а за деякими показниками перевершує їх. У структурі харчування людини важливе місце займає споживання кулінарної продукції, серед якої високим попитом користуються вироби із заварного тіста. У загальній структурі ринку харчової промисловості вироби із заварного тіста займають вагому частку, і становлять сегмент, який динамічно розвивається. Тому наші наукові інтереси були зосереджені на розробці жировмісної кулінарної та кондитерської продукції, виробах із заварного тіста. Аналітично підтверджено, що реалізація технологічного процесу виробництва виробів із заварного тіста визначається переважно технічними та технологічними властивостями жирового компоненту. Проведено порівняльний аналіз жирнокислотного складу традиційних для заварного тіста жирових компонентів (масла вершкового та маргарину) з олією соняшниковою високоолеїнового типу. У статті наведено результати досліджень структурно-механічних властивостей заварного тіста з використанням олії соняшникової високоолеїнового типу та фізико-хімічні показники випечених напівфабрикатів із нього. Визначено пластичну в’язкість та інші показники деформації заварного тіста залежно від вмісту олії та води в модельній системі. Установлено, що оптимальна концентрація олії у рецептурі – 32%, за даної концентрації питомий об’єм випеченого напівфабрикату становить 7,3 см3/г; формостійкість – 1 у.о.; упік – 39 %; усушка – 4,4%. Вивчення властивостей жирового рецептурного компонента заварного тіста в умовах моделювання технологічного процесу дозволить управляти і забезпечити отримання конкурентоспроможної продукції, що має збалансований склад за харчовою та біологічною цінністю.
