"Dainty Predators" and "Carnivorous Families": The Representation of Hunger in Jessica Hagedorn’s Dogeaters
Authors: I. Rawashdeh Faisal , J. Zuraikat Malek
Published: April 2019

The cultural practice of obsessive feasting suggests not only individual attitudes to food but also a collective state of spiritual emptiness. In Jessica Hagedorn’s Dogeaters (1990) most male characters’ hunger for food is never satisfied. Their expressed desire to eat at any given circumstance is often aligned with vocalized or wishful sexual urges. Their female counterparts either eschew food ascetically or demonstrate a corresponding degree of gastronomic crave. In this novel, hunger and its direct association with consumption do not define a festive, harmonious environment. Rather, satisfaction of desires is set against a violent, politically charged background. The discussion below traces the representation of hunger and food consumption in the novel to gain fresh insights into the problematic nature of the neocolonial modes of living in Manila. To this end, we argue that Manila in Hagedorn’s Dogeaters is consumed by a collective insatiability and instability fostered by the hegemony of a capitalistic/postmodern dynamic that continues to define the cultural attitudes and practices of the citizenry in the neocolonial city of Manila.

Authors: B. Shenderuk Olena , L. Tamarkina Olha , P. Pernarivska Tetiana
Published: April 2019

Knowledge of foreign languages to a great extent depends on a teacher’s methods and methodological approaches. Among the number of certain methods we choose grammar-translation and direct methods. In spite of the fact that these methods were popular last century, they are still widely used nowadays. The usage of them presented their fundamental advantages and some disadvantages, used in our practice. This paper was written on the basis of theoretical aspects’ research of the problem, on analysis and synthesis of scientific literature and on personal experience of teaching English during nearly one year in Chernihiv Academy of the State Penitentiary Service (Ukraine). During this period of time we were observing the problem of teaching English with the help of grammar-translation and direct methods by the students and cadets who were taught with the help of these methods. Studying the problem of grammar-translation and direct methods in teaching English is acute because of increasing role of English, on the one side, and demands which are promoted to future law specialists, on the other hand. The significance of this issue arises in detection of peculiarities in teaching English in the educational institution with specific conditions of study. Solving this problem with the help of differentiated approach to teaching English to students and cadets facilitates high qualitative changes. Novelty is in applying famous methods such as grammar- translation and direct methods in the new surroundings. The results of our work were described and compared in this paper. The findings revealed the implementation of the mentioned methods in the high institution with specific conditions of studying. The described methods can be admitted by other foreign language teachers. However, we reached a conclusion that the mentioned methods may be modified.
Reflections on Discussions of Literature: A Language Learning Environment to Promote Speaking Skills
Authors: Tugrul Mart Cagri
Published: April 2019

Classroom discussions of literature create a pedagogically sound platform in the ELT classroom for language acquisition to take place. The pedagogic rationale for embracing literature discussions lies in the claim that they lend the necessary guidance language learners need to construct meaning, promote comprehension and seek ways to articulate their ideas, opinions and interpretations. This article discusses benefits of implementing literature discussions with undergraduate ELT students to empower their growth in oral communication. The data revealed favorable responses toward using literature discussions in language learning with regard to their benefits in building a solid foundation for learners to experiment with language by means of dialogic exchanges for the development of speaking skills.

The Heat Transfer Problem in a Rigid and Nonconvex Gray Body with Temperature Dependent Thermal Conductivity
Authors: SALDANHA DA GAMA Rogério Martins , MARTİNS-COSTA Maria Laura
Published: April 2019

This work studies coupled steady-state conduction-radiation heat transfer in a non-convex gray body when the thermal conductivity temperature-dependent. The gray-body assumption is an improvement with respect to the black body model, because in this model a portion of the incident radiant energy can be reflected from the body boundary. The problem is mathematically described by a nonlinear partial differential equation subjected to a nonlinear boundary condition involving a Fredholm operator which arises from the non-convexity of the body. In this problem the absolute temperature distribution is the unknown, as in the case of a black body. The Kirchhoff transformation is employed to linearize the partial differential equation, giving rise to new boundary conditions. The solution of the problem is constructed by a proposed iterative procedure, employing  sequences that involve the temperature and the radiosity. The convergence is explicitly demonstrated.  Besides, an error estimate, for each element, is presented. It is remarkable that the results obtained for black bodies are a particular case of this work. In other words, the results presented in reference [1] consists of a particular case of this paper, obtained when the emissivity is equal to one.

Design/Methodology: This research depends on archival data collected from the NSE. Firms have been chosen based on the convenient sampling method and an important parameter for judgment is Conglomerated firms. In order to get genuine results, ten years of financial data have been taken into consideration. Multiple regression technique was used to analyze the data. The software used for analysis was STATA version 14.0.
Results: The model I of the study disclose a pessimistic and insignificant impact of board size and board independence on IC using VAIC as a proxy. In contrast, model II results disclosed that the performance of the firms was impacted by the board’s size and institutional ownership. Implying that, the greater the size of the firm as well as more shares owned by institutional shareholders the higher the profit.
Practical Implications: Nigeria being one of the growing economies now is dependent on knowledge assets and hence it has a positive effect on the firm’s performance. Conglomeration is seen even between employee’s skills of both industries, which give a positive outcome. Hence, firms under conglomerate tags have a strong impact in relation to intellectual capital.

Наведено методику вивчення сортів фундука за морфологічними характеристиками листків, яка базується на визначенні розмірів листкової пластинки та черешка листка, загальної форми листкової пластинки, форми верхівки, основи, вираженості зубців. Виявлено відмінність і подібність окремих сортів фундука селекції УкрНДІЛГА за морфологічними ознаками листя. Показники довжини черешків листків сортів є більш мінливими, ніж розміри листків. Наявні сорти як із видовженими, округлими, так і з широко-округлими листками. Проведене попарне порівняння 12 сортів за 8 ознаками виявило, що ступінь подібності та відмінності сортів є різною. Найбільшою подібністю за морфологічними ознаками всіх компонентів листкових пластин характеризуються сорти ‘Клиновидний’ і ‘Пірожок’, які відрізняються лише за формою верхівки листка та незначно – за формою основи листка. Сорти ‘Лозівський шаровидний’ і ‘Олімпійський’, ‘Олімпійський’ і ‘Серебристий’ та ‘Серебристий’ і ‘Велетень’, навпаки, відрізняються за всіма досліджуваними ознаками. Загалом переважають відмінні ознаки, що вказує на можливість використання наведеної методики для характеристики та ідентифікації сортів.

Проведено аналіз динаміки патологічних процесів у лісових насадженнях Харківської області за базами даних УкрНДІЛГА щодо лісових насаджень, в яких зареєстровані патологічні процеси, за період 1992–2012 рр. Відзначено поступове нерівномірне збільшення площ соснових і дубових насаджень, що всихають. Станом на 2009 р. поширення патологічних процесів набуло дуже сильного ступеня (11,7 % від вкритої лісом площі). На основі кореляційного аналізу відзначено зростання масштабів патологічних процесів у соснових насадженнях за зниження сонячної активності (числа Вольфа). Зроблено прогноз щодо можливого зменшення масштабів всихання у 2023–2024 рр.
ФУНКЦІОНАЛЬНО-ЦІЛЬОВА ТА ВІКОВА СТРУКТУРА ГІРСЬКИХ ЛІСІВ УКРАЇНСЬКИХ КАРПАТ
Authors: Hudyma V. D. , Parpan Т. V. , Plikhtiak P. P.
Published: April 2019

У гірських лісах лісостани з домінуванням бука лісового займають 43 % площі, ялини європейської – 42 %, ялиці білої – 8 %, інших видів – 7 %. Експлуатаційні ліси займають 45,5 % площі, захисні – 27,7 %, природоохоронні – 17,5 %, рекреаційно-оздоровчі – 9,3 %. У кожній категорії є ліси, можливі для головного користування і виключені з користування. Ліси, можливі для експлуатації, займають близько 487 тис. га, виключені з розрахунку головного користування – 479,8 тис. га. Результатом лісосічних рубок є фрагментація лісового покриву, переважання одновікових деревостанів, зміни розподілу за класами віку. У лісах, можливих для експлуатації, частка деяких вікових груп у лісостанах усіх панівних видів у рази відрізняється від оптимальної. У виключених із головного користування лісах на практиці застосовують такі самі критерії оптимальності вікової структури, що й для експлуатаційних лісів. Водночас у них доцільнішим є застосування ідеї «різновікового лісу», за якої основним показником стану має бути стійкість і стабільність лісових екосистем. Розглядати вікову структуру похідних ялинників з погляду оптимальності недоречно, оскільки їх треба замінити на корінні деревостани. Наявність їхніх молодняків свідчить про певні недоліки в лісовідновленні.

The primary goal of periodontal treatment is to stop periodontal disease progression and reduce future risks in disease recurrence. In order to overcome the limitations of the conventional treatment, controlled drug delivery systems for application in periodontal pockets have been developed. Their use offers several advantages: the therapeutic agent is targeted directly to the disease site and concentrations are 10-100 folds higher than the concentrations achieved by systemic administration, with low incidence of side effects.
The PerioChip® is as local controlled-release biodegradable delivery system containing chlorhexidine digluconate. Several multicenter clinical trials have shown that the application of the PerioChip® in periodontal pockets as adjunct to the conventional periodontal treatment significantly improved the clinical parameters. In this article, the results from controlled clinical studies aimed to evaluate the clinical and microbiological efficacy of the PerioChip®, are discussed.

Many natural products could serve as the starting point in the development of modern medicines because of their numerous biological and pharmacological activities. However, some of them are known to carry toxicological properties as well. In order to achieve a safe treatment with plant products, numerous research studies have recently been focused on both pharmacology and toxicity of medicinal plants. Moreover, these studies employed efforts for alternative biological assays. Brine Shrimp Lethality Assay is the most convenient system for monitoring biological activities of various plant species. This method is very useful for preliminary assessment of toxicity of the plant extracts. Rapidness, simplicity and low requirements are several advantages of this assay. However, several conditions need to be completed, especially in the means of standardized experimental conditions (temperature, pH of the medium, salinity, aeration and light). The toxicity of herbal extracts using this assay has been determined in a concentration range of 10, 100 and 1000 µg/ml of the examined herbal extract. Most toxicity studies which use the Brine Shrimp Lethality Assay determine the toxicity after 24 hours of exposure to the tested sample. The median lethal concentration (LC50) of the test samples is obtained by a plot of percentage of the dead shrimps against the logarithm of the sample concentration. LC50 values are estimated using a probit regression analysis and compared with either Meyer’s or Clarkson’s toxicity criteria. Furthermore, the positive correlation between Meyer’s toxicity scale for Artemia salina and Gosselin, Smith and Hodge’s toxicity scale for higher animal models confirmed that the Brine Shrimp Lethality Assay is an excellent predictive tool for the toxic potential of plant extracts in humans.

The composition of the volatile aroma components was defined in the infusion prepared by stems of Sideritis raeseri (SR-S) from R. Macedonia, Albania and Greeсe and in the infusion of rosette leaves of S. raeseri (SR-R) from R. Macedonia. Analysis were made by
gas chromatography (GC/FID/MS) equipped with a headspace (HS) sampler. Twenty components (12 monoterpenes representing 76.70- 94.84% and 8 sesquiterpenes representing 5.16-18.55% of the entire volatiles) were identified as aroma components in SR-S samples. The predominant components in all samples were β-pinene, α-pinene and trans-сaryophyllene. The high abundance of limonene and δ-3-сarene were characteristic for the samples from Greeсe and 1,8-сineole was for the samples from R. Maсedonia and Albania. In the infusions of SR-R, ten components were identified, 5 monoterpenes (73.20-83.89%) and 5 sesquiterpenes (16.10-26.80%). Prevailing components in
all tested samples of SR-R were β-pinene, α-pinene, 1,8-cineole and α-epi-murolol. There was almost no difference in the chemical profiles of the aroma compounds between SR-S and SR-R. Infusion of rosette leaves exhibit very similar aroma compounds profile with the infusion of stems of S. raeseri.

Published: April 2019

Probiotics, prebiotics, and synbiotics are functional components able to exert positive effects on human health. Numerous medical conditions lack effective and safe approaches for prevention or treatment, thus usage of probiotics, prebiotics, and synbiotics is an alternative. Further, the benefit related to the consumption of these compounds is associated with lower morbidity of chronic diseases and reduced health-care costs. Various types of mediums to deliver probiotics/synbiotics to the human GIT are used. Although capsules and tablets are frequently applied as delivery systems for probiotics, the major challenge of the commercial sector is to market new functional
foods containing probiotics and/or prebiotics. Discovering of new probiotic/synbiotic functional foods is connected to the interest of the food industry to revitalize continuously through introduction of products with improved nutritional value and pleasant taste, but also with health benefit for the consumers. The review provides insights and new perspectives in respect to usage of functional components and foods
in prevention and treatment of inflammatory bowel diseases (IBD) that are highly correlated with the modern lifestyle. The therapeutic and safety properties of probiotics and prebiotics, their role in pathogenesis of IBD, potential to prevent and treat these diseases as well as postulated mechanisms of action will be discussed, highlighting the main areas in which further research is an emergence.

Published: April 2019

Identification and characterization of antigens present at the human peripheral nerve is a great challenge in the field of neuroimmunology. The latest investigations are focused on the understanding of the biology of glycoconjugates present at the peripheral nerve, and their immunological reactivity. Increased titers of antibodies that recognize carbohydrate determinants of glycoconjugates (glycolipids and glycoproteins) are associated with distinct neuropathic syndromes. There is considerable cross-reactivity among anti-ganglioside antibodies, resulting from shared oligosaccharide epitopes, possibly explaining the overlap in syndromes observed in many affected patients. Sera
from patients with neuropathies (GBS, chronic inflammatory demielynating polyneuropathy - CIDP, multifocal motor neuropathy - MMN), cross-react with glycoproteins isolated from human peripheral nerve and from Campylobacter jejuni O:19. The frequency of occurrence of antibodies against these glycoproteins is different, depending of the type of neuropathy. Identification of the cross-reactive glycoproteins and possible additional auto antigens could be useful in laboratory evaluation of peripheral neuropathies and help to develop a more effective therapeutic approach.

Chemical characterization of three Juniperus species: J. foetidisima (JF), J. excelsa (JE) and J. communis (JC) from Macedonian flora enclosed determination of yield and essential oil composition of the oils obtained by hydro-distillation of dried leaves and determination of the content of total phenols and total flavonoids in dried plant material. GC/FID/MS analysis showed mainly monoterpene profile of the JC oil and combined monoterpene/sesquiterpene profile of JF and JE oils. Sesquiterpene cedrol was found as an important constituent of the JF and JE, thus the JF oil was characterized by three main components (a-pinene, limonene and cedrol, in amount up to 67.63%, 27.11% and 33.91%, respectively) and JE oil by four components (a-pinene, sabinene, cis-thujone and cedrol, in amount up to 33.83%, 29.49%, 26.20% and 24.44%, respectively). The JC oil was free of cedrol, but contained relatively large sesquiterpene fraction (sesquiterpene hydrocarbons and oxygen containing sesquiterpenes in amounts up to 28.64% and 13.57%, respectively). The JC oil was characterized by three monoterpene components (a-pinene, sabinene and terpinen-4-ol, presented up to 28.68%, 16.27% and 12.16%, respectively). The content of total phenols determined by Folin-Ciocalteu method ranged from 96.18-122.91 mg GAE/g dw (water extraction) while the content of total flavonoids ranged from 2.05-11.91 mg CE/g dw (ethanol extraction). Both water and ethanol extracts possessed radical
scavenging activity against DPPH radical. Water extracts were more powerful with % of inhibition of DPPH ranging up to 64.52%, 67.40% and 78.23% for water extract (10 mg/ml) of JF, JE and JC, respectively. Obtained results showed correlation with the content of total
phenols.

Published: April 2019

Zirconium dioxide as core ceramic material for dental crowns and bridges, possess high strength, chemical stability and superior aesthetics after veneering. Veneering ceramic is considered to be the weakest part of all-ceramic restorations. The adhesion between the core and veneering porcelain is based on the manner in which the connection occurs in metal-ceramic structures. Standard procedures for connecting zirconia to hard dental tissues and veneering materials do not achieve the required strength of bonding.
The aim of the paper is to investigate different surface treatments of the zirconium dioxide ceramic core and find the best, for achieving highest adhesive bonding values to veneering porcelain. The study was primarily designed to investigate the bonding strength of the veneering porcelain to zirconia with in vitro Macro shear bond strength test. The specimens with different surface treatment of the zirconia were divided in five groups of twelve according to the treatment of zirconium surface and results showed highest bonding values for specimens treated with Rocatec system.
