Authors: Nabil Tamer , Soliman Ahmed Hussein
Published: October 2019

In this work, we introduce notions of generalized firmly nonexpansive (G-firmly non expansive) and fundamentally firmly nonexpansive (F-firmly nonexpansive) mappings and utilize to the same to prove Ray's theorem for G-firmly and F-firmly nonexpansive mappings in Hilbert Spaces. Our results extend the result due to F. Kohsaka [ Ray's theorem revisited: a fixed point free firmly nonexpansive mapping in Hilbert spaces, Journal of Inequalities and Applications (2015) 2015:86 ].

Authors: Rogers Frank Dewayne
Published: October 2019

This articleâ€™s goal is to support the existence of the dual in a Linear Fuzzy Real environment and focus on its application to Linear fuzzy program problems. This concept will apply to linear fuzzy programming problems that contain fuzzy constraints with a crisp objective function, crisp constraints with a fuzzy objective function, or fuzzy constraints with a fuzzy objective function. It is also proposed here that optimizing fuzzy constraints and objectives of the dual linear program that consist of a triplet and are much like triangular fuzzy numbers, but differ in that they are a hybrid fuzzy number that contains characteristics that are both fuzzy and crisp.

Carbon Fiber Polymer Composites
Authors: Markovičová Lenka , Zatkalíková Viera , Hanusová Patrícia
Published: October 2019

Carbon fiber reinforced composite materials offer greater rigidity and strength than any other composites, but are much more expensive than e.g. glass fiber reinforced composite materials. Continuous fibers in polyester give the best properties. The fibers carry mechanical loads, the matrix transfers the loads to the fibers, is ductile and tough, protect the fibers from handling and environmental damage. The working temperature and the processing conditions of the composite depend on the matrix material. Polyesters are the most commonly used matrices because they offer good properties at relatively low cost. The strength of the composite increases along with the fiber-matrix ratio and the fiber orientation parallel to the load direction. The longer the fibers, the more effective the load transfer is. Increasing the thickness of the laminate leads to a reduction in the strength of the composite and the modulus of strength, since the likelihood of the presence of defects increases.

The aim of this research is to analyze the change in the mechanical properties of the polymer composite. The polymer composite consists of carbon fibers and epoxy resin. The change in compressive strength in the longitudinal and transverse directions of the fiber orientation was evaluated. At the same time, the influence of the wet environment on the change of mechanical properties of the composite was evaluated.

Determination of steroid esters in hair of slaughter animals by liquid chromatography with tandem mass spectrometry
Authors: Matraszek-Żuchowska Iwona , Woźniak Barbara , Sielska Katarzyna , Posyniak Andrzej
Published: October 2019

Introduction

The use of growth promoters in animal husbandry to increase weight gain and efficiency of feed conversion into muscle has been banned in the European Union since 1988, and under Directive 96/23/EC, surveillance for anabolic steroid hormones is obligatory. The hormones present in animal tissues may be of endogenous origin or may result from illegal administration. Steps have been taken to determine selected steroids in the form of esters in the alternative matrix of animal hair. Their detection in biological material is direct proof of the illegal use of anabolics.

Material and Methods

The procedure for the determination of steroid esters in animal hair, based on digestion, extraction, purification, and liquid chromatography with tandem mass spectrometry was validated under the current regulations. In total, 348 samples of animal hair were examined using this method.

Results

Good recoveries and precision values (RSD) were obtained during validation. Decision limits (CCα) and detection capabilities (CCβ) were in the ranges of 2.57–4.18 μg kg−1 and 4.38–7.12 μg kg−1, respectively. The method met the criteria for confirmation techniques with respect to Commission Decision 2002/657/EC.

Conclusion

Testing for steroid esters in animal hair was introduced into the National Residue Control Programme in 2017. Steroid esters were not found in any hair samples above the CCα, which indicates that illegal use of anabolics was not confirmed.

The Challenges and Strategies of Teachers in Teaching TOEFL and IELTS Test Preparation
Authors: Roza Delvia
Published: October 2019

High-stake English proficiency tests, such as TOEFL and IELTS, open up opportunities for the people in Indonesia to study in reputable universities, both local and abroad. Since Indonesian learners are non-native English speakers, some institutions help them to overcome the problems they have with the tests. Related to these issues, the teachers may face some challenges in teaching the students who want to reach their target scores. For that reason, this study was conducted to find out: 1) teacher challenges in teaching the TOEFL and IELTS tests, and 2) teacher strategies in motivating the students. The location of the study was in an English educational institution in Pekanbaru. The participants were 10 teachers who had taught these tests preparation for more than two years. The method used was a qualitative approach with face-to-face interviews as the data collection instrument. It was found that the challenges of the teachers in teaching the tests were 1) students’ high expectations, 2) lack of effort from students, 3) study time limitations, 4) teachers’ experience, 5) issues with high school students, and 6) the number of students in a class. It was also found that the teachers’ strategies in motivating the students were 1) students’ awareness of the opportunities of passing the tests, 2) fun learning, 3) telling stories of people who are successful through passing the tests, and 4) reminding the students why they joined the class, spending much money, time and energy on these tests. All in all, though teachers faced some challenges in teaching IELTS and TOEFL tests, they also had strategies to overcome them.

Structure–property Effects in the Generation of Transient Aqueous Benzoic Acid Anhydrides by Carbodiimide Fuels
Authors: Kariyawasam Lasith , Kron Julie , Sommer André , Hartley Scott
Published: October 2019

The design of dissipative systems, which operate out-of-equilibrium by consuming chemical fuels, is challenging. As yet, there are few examples of privileged fuel chemistry that can be broadly applied in abiotic systems in the same way that ATP hydrolysis is exploited throughout biochemistry. The key issue is that designing nonequilibrium systems is inherently about balancing the relative rates of coupled processes. The use of carbodiimides as fuels to generate transient aqueous carboxylic anhydrides has recently been used in examples of new nonequilibrium materials and supramolecular assemblies. Here, we explore the kinetics of formation and decomposition of a series of benzoic anhydrides generated from the corresponding acids and EDC under prototypical conditions (EDC = N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride). The reactions can be described by a simple mechanism that merges known behavior for the two processes independently. Structure–property effects in these systems are dominated by differences in anhydride decomposition rate. The kinetic parameters allow trends in concentration-dependent properties to be simulated, such as reaction lifetimes, peak anhydride concentrations, and efficiencies (i.e., total anhydride produced per equivalent of carbodiimide). For key properties there are diminishing returns with the addition of increasing amounts of fuel. This is particularly significant for the lifetimes, where substituent effects exert a much greater influence than fuel quantity under typical conditions. These results should provide useful guidelines for the design of functional systems making use of this chemistry.

Single crystal XRD studies reveal the molecular structure as a one-dimen­sional (1D) coordination polymer (CP) with the composition [Cu(phen)(NO3)2]n. The FT-IR spectrum of CP further ascertains the binding modes of the ligand moiety. The copper ion is present in the +2 oxidation state and the geometry around the central metal ion is distorted square pyramidal. Moreover, CP shows a brilliant catecholase-like activity in methanol, which can easily oxidize the substrate 3,5-di-tert-butylcatechol (3,5-DTBC) to its respective quinone. Kinetic measurements suggest that the catechol oxidation rate follows saturation kinetics with respect to the substrate and first order kinetics with respect to the catalyst. CP shows a very good catalytic activity with Kcat = 8.28 h–1.

Diabetes mellitus is a metabolic disease characterized by elevated blood glucose levels. Medicinal plant Ferulago angulata has anti-oxidant properties. The aim of the present research was to evaluate the effect of a hydroalcoholic extract of F. angulata on the blood glucose level and liver enzyme activity in diabetic male rats. Forty-eight male rats were randomly divided into eight groups, including normal and diabetic groups. Diabetes was induced by a single intraperitoneal injection of streptozotocin at 40 mg·kg-1 body weight. Rats were treated with an intraperitoneal injection of the extract for three weeks. At the end of the experimental period, fasting blood samples were collected, and blood glucose and liver enzyme activity were measured. This study demonstrated that serum glucose levels in diabetic groups treated with F. angulata were significantly lower than those in diabetic rats (P < 0.001). Alanine aminotransferase levels in diabetic rats treated with F. angulata were significantly decreased compared to diabetic rats (P < 0.001). Aspartate aminotransferase levels in diabetic rats treated with 200 and 400 mg·kg-1 F. angulata were significantly decreased compared to diabetic rats (P < 0.001). No significant differences were observed in the serum levels of blood glucose and liver enzymes in the normal group treated with different doses of the extract. These results show that the hydroalcoholic extract of F. angulata might be effective in the treatment of diabetes and consequently alleviate the liver damage caused by streptozotocin-induced diabetes mellitus. This effect might be due to the presence of flavonoids and their antioxidant features.
SELF-SIMILAR AND LASER-LIKE REGIMES IN NUMERICAL MODELING OF HASSELMANN KINETIC EQUATION FOR OCEAN WAVES

The absence of mathematically justified criteria in the models of prediction of wind waves of the ocean, used by the world’s largest centers NOAA (USA) and ECMWF (UK), based on numerical modeling of the Hasselmann kinetic equation, led to erroneous hierarchy and erroneous nonlinear interaction approximation, wind forcing and waves dissipation terms due to wave-breaking. Existing models of wind waves operate in the paradigm of the adjustable «black box», each time requiring reconfiguration. On the basis of numerical simulation, we were able to construct a model, taking into account the wind forcing of the power type in combination with the «implicit» dissipation.

Published: October 2019

El uso de internet simboliza una nueva práctica dentro de la comunicación política que tendrá un impacto en las actitudes políticas de las y los jóvenes. Éstos representan a una parte muy importante de la población en la Zona Metropolitana de Monterrey, Nuevo León México (ZMM); aproximadamente el 28.75% (a marzo de 2019) de la lista nominal. La metodología que se utilizó fue de corte cuantitativo, ya que se aplicó encuesta de opinión a las y los jóvenes entre 18 y 29 años. Los objetivos planteados son los siguientes: identificar los niveles de uso de internet en materia política, de interés en la política, de eficacia política interna y de confianza en las instituciones políticas y de gobierno. Asimismo, se tiene la intención de determinar si el uso de internet en lo que corresponde al área política explica las diferentes actitudes políticas de los jóvenes en la ZMM. Los resultados más relevantes muestran que los niveles de interés en la política y la sensación de eficacia política interna son positivos. Por otra parte, la confianza en las instituciones políticas y de gobierno es muy baja, mientras que el menor nivel de confianza se tiene frente a los partidos políticos y la Presidencia de la República. Es importante resaltar que el uso de internet con fines políticos presenta un nivel explicativo relevante frente al interés en la política y medianamente importante sobre la sensación de eficacia política interna.

Published: October 2019

The importance of acquiring information literacy (IL) knowledge and skills in high schools as a prerequisite to entering colleges and universities has been well-documented in the literature (e.g., Cahoy, 2002; Fitzgerald, 2004; Saunders, Severyn, & Caron, 2017).  This paper investigates the IL knowledge of Canadian and international high school graduates, as they enter a university in Canada. More specifically, the focus is on information seeking behaviour (ISB), part of the Access and Evaluation stages of the IL spectrum (Sparks, Katz, & Beile, 2016).
GIS for School Libraries Emergency Planning

Published: October 2019

Geographic Information Systems (GIS) are a means of providing great contributions to users in decision making processes based on location. It presents the information to the users serves and provides data collecting, storing, processing, managing, analyzing, querying. GIS ensures that a lot of data are layered on the architectural plans of school libraries. A data that is not well evaluated due to the data intensity in the analysis studies may prevent both the delay and the accuracy of the desired diagnosis for solution. For this reason, GIS technology is used in places where intensive data usage. GIS, which has been started to be used by different disciplines together with technological developments, enables the storage and processing of all kinds of data to be analyzed. It is a system consisting of necessary hardware and software and users for these processes. It is a tool that enables effective management of data. Complex data is easily analyzed by users in a database by GIS software. It is also concerned with the association of spatial data and non-graphical (verbal) data. GIS is able to compare measurement results successfully according to conventional measurement evaluation methods. There are also a number of projects where GIS has been implemented in interior areas. School libraries can also serve in many areas or more than one floor. The GIS layers must be shown on floor plans as emergency exit doors, location of emergency intervention tools (fire extinguisher, fire hose, hydrant, fire alarm buttons, electric panel, gas valve, first aid kit etc.), nearest emergency service centers (fire brigade, police, ambulance, etc.), evacuation routes leading to emergency assembly area, external, main and service ladders, building non structural materials. As there are many people in schools and school libraries as a number of users, in case of fire, their evacuation must also be fast. GIS will also provide effective planning for rapid evacuation of schools and school libraries. Digital data obtained from service providers such as municipalities, water, natural gas companies can also be used as separated GIS layers. All building elements in the building can be classified in different colors and typologies for each floor (Balcony, wall, threshold, hall, stairs, room, window, shelves etc.). Emergency lighting kits should be installed in school libraries. Sensors, which are part of the fire alarm system, must also be located in the GIS layers. Furniture and furnishings used in the floors can also be shown on the GIS. Routes to be used by disabled users in emergency situations should be specified in these plans and physical arrangements such as ramps should be implemented. Area names in the school and in the school library should also be included in the GIS layers. The joint meetings should be held with the school library experts working in this field in the world, problems should be discussed, national and international networks should be established.
The Effect of “The Book Characters Are Among Us” Activity on the Reading Culture of Students
Authors: Ordu Rahime
Published: October 2019

We live in an era where knowledge becomes very diverse, expands and change quickly. Reading is the most effective way in order to follow the knowledge, which is accelerated by the democracy and developments of the communication technologies. Therefore, modern societies give special attention to the activities regard to the reading culture.

Nowadays, we are facing a young generation which does not need and care about reading as well as does not know how/why to read a literature writing. This generation prefers a consumption based artificial game world which is served via computer technologies and this kind of artificial places that internet cafes and game centers serve rather than reading and going to libraries.

This study aims to present “Book Characters Are Among Us” activity which makes reading interesting for teenagers by connecting reading with drama and improves their reading, writing and speaking skills. In addition, it evaluates the results of the activity which was held with a group of students.

It was observed that, students started being interested in reading books, doing critical reading to understand and know the characters in the books, obtaining the creative thinking and writing experience and improving their speaking abilities that’s to “Books Are Among Us” activity. The activities were intentionally organized in Z Library in order to make students be aware of the facilities and possibilities which were given to their usage. The factors such as comfortable sitting zones, easiness of reaching a book, computer technology, being wide and spacious, usage of the place for book interviews, presentations and drama activities other than book taking and returning are the reasons for students to come to Z Library.
