Published: March 2019

The aim of the study was to compare ratios of total and free fractions of iodothyronines (T3/T4, fT3/fT4) and integral thyroid index ((fT3 + fT4)/TSH) in euthyroid subjects that had negative of antibodies values and euthyroid subjects that had positive antibodies (antibodies to thyroid peroxidase - AntiTPO and / or antibodies to thyroglobulin - AntiTG). Methods. A total of 95 apparently healthy people were enrolled in this study and classified into two groups. Group A (n = 72) had normal values of thyroid hormones and negative values of antibodies, i. e. AntiTPO < 50 IU/ml and/or AntiTG < 100 IU/ml. Group B (n = 23) had normal values of thyroid hormones and positive antibodies, i.e. AntiTPO > 50 IU/ml and/or AntiTG > 100 IU/ml. Serum thyroid hormones and antibodies concentration was measured by enzyme immunoassay. Results. Euthyroid subjects with positive thyroid antibodies have less values of (T3 + T4)/TSH (Me = 12,9 vs. 15.7, p = 0.01), T3/T4 (Me = 0.015 vs. 0.017, p = 0.02) and fT3/fT4 (Me = 0,24 vs. 0.27, p = 0.03) ratios than subjects with negative antibodies, as well as value of free triiodothyronine (Me = 3.9 vs. 4.7 pmol/l, p = 0.02). In the group of individuals with positive antibodies AntTPO significantly correlated with thyroid-stimulating hormone (r = 0.45; p = 0.02) and T3/T4 ratio (r = -0.43; p = 0.03). Conclusion. This finding may point to a decreased ability of tissues thyroxine deiodination in individuals with elevated thyroid antibodies levels.

This research is motivated by the low ability to write free poetry for fifth grade students at SD Negeri 161 Pekanbaru. This isbecause there are still teachers who are less creative in giving lessons to students. For free poetry, two-dimensional picturemedia is a suitable for use. This research aims to determine the differences in the ability to write free poetry for studentsusing two dimensional picture media. This research method uses quasi nonequivalent control group design experiments. Thisresearch was conducted in two classes V in SD Negeri 161 Pekanbaru, namely VB as the control class and VC as theexperimental class, with each class totaling 30 students. Based on the results of the research obtained the ability to write freepoetry for students who learn using two dimensional picture media better and higher increase than students who learnwithout using learning media. It can be seen from the gain index in the experimental class using two dimensional picturemedia by 49% which is the medium category, while the gain index in the control class without using learning media is 17%which is a low category.

This study aims to determine the differences in students mathematics learning outcomes in the experimental class using theindex card match learning strategy with the control class using conventional learning. This study uses quasi experimentalmethod with nonequivalent control group design. This design uses two groups, namely the experimental group and thecontrol group. The experimental group is the class that gets treatment while the control group is the class that is not treated.This research was conducted at SD Negeri 39 Pekanbaru in class V. The results of the study based on the experimental classt test and the initial test control class (pretest) that is t_count <t_table or 1.760 <2.016 so that it can be interpreted that thereis no difference. The results of the final test t meet the criteria t count> t table or 2.769> 2.016, which means that there is adifference between the experimental class students and the control class at the final test (posttest). This means that there aredifferences in students mathematics learning outcomes in the experimental class using the index card match learning strategywith the control class using conventional learning. This shows that the index card match learning strategy can affect themathematics learning outcomes of class V students SD Negeri 39 Pekanbaru.

O termo empreendedorismo está sendo disseminado e estudado neste século, com ênfase no fato de não existir empregos para todos, constituindo uma saída para manutenção da atividade econômica da população. Em que o termo empreendedorismo significa mais do que uma denominação ou um conceito, trata-se de um comportamento, de uma atitude, estando associado à inovação, possibilidades de fazer coisas novas ou de maneira diferente, assim como a capacidade de assumir riscos. O referido trabalho apresenta um estudo de abordagem qualiquantitativa, desenvolvido através de pesquisa descritiva, bibliográfica e de campo, feita com 10 empreendedoras do curso de Administração de uma faculdade particular em Juazeiro do Norte/CE. Diante do exposto, o trabalho teve como objetivo geral analisar os desafios encontrados pelas empreendedoras que estudam em uma faculdade particular, no curso de administração, e como objetivos específicos compreender as faces do empreendedorismo feminino, traçar o perfil das empreendedoras, e identificar as razões que as motivaram para se tornar empreendedoras. Os resultados da pesquisa indicaram que o perfil delas é composto por mulheres jovens, que são mais propensas ao risco, solteiras e sem filhos e os motivos que levaram a abrir o empreendimento são diversos desde o desemprego, a independência financeira, a vocação e realização profissional. Diante do exposto, percebe-se que as mulheres estão empreendendo cada vez mais cedo, procurando tanto a satisfação profissional quanto a independência financeira, para depois pensar em constituir uma família, e os desafios enfrentados pelas mesmas são enfrentados em todos os gêneros, pois é uma questão mundial, desde a concorrência exacerbada, às crises mundiais. 
The Analysis of The Translation of 'אֲמֻצִּים' In Zechariah 63 and 67
Authors: Chia Philip Suciadi
Published: March 2019

There are some ancient sacred texts for Christianity such as Hebrew Bible, Syriac Peshitta, Septuagint, Aramaic Targum and Latin Vulgate. However, the translation of these ancient texts is not always having the same nuance or literal meaning. Zechariah 6:3 and 6:7 are one example. The word “אֲמֻצִּים” or strong has been translated diversely in our ancient sacred texts. Therefore, this paper will attempt to discuss multiple translations for the word “אֲמֻצִּים” or strong. The discussion will cover the purpose of these various translations. The possible reason behind the selection of the meaning will also be discussed in this paper.

The production of chicken eggs on a widespread industrial level has led to the generation of a large amount of egg shells. These egg shells are considered to be bio-hazardous waste materials although they are a rich source of amino acids and minerals. In the present investigation, effort has been made to incorporate waste poultry egg shell particles (ESP) both in carbonized (C) as well as uncarbonized (UC) form into the matrix of an Aluminum-Silicon (Al-Si) alloy to improve its mechanical properties. Various mechanical properties of the resulting composites such as tensile strength, modulus of elasticity, hardness, toughness, impact and compressive strengths have been determined and found to increase after the addition of the ESPs confirming that the incorporation of waste ESPs in the Al-Si matrix serve as reinforcements. The increase in mechanical properties such as the hardness (10.2% - UC, 19% - C), tensile (6.61% - UC, 10.61% - C), compressive (9.12% - UC, 63.94% - C) and impact strengths (30.07% - UC, 302.35% - C) is more pronounced in the case of carbonized ESPs. Field-Emission Scanning Electron Microscopy (FE-SEM) has been conducted to determine the compositions of the matrix materials as well as the composites.
A New Cryptographic Scheme Utilizing the Difficulty of Big Boolean Satisfiability
Authors: Ahmad Waleed , Rushdi Ali Muhammad Ali
Published: March 2019

A search problem may be identified as one, which requires an actual “search” for an answer or a solution. Such a problem may have no obvious method, which could be followed to determine a solution, other than to intelligently search through all candidate or potential solutions, which constitute the search space, until a satisfactory one is found. Typically, we may have an efficient way of determining whether one of the possible solutions is actually correct, but no efficient way of determining how to find a correct solution. There are many such search problems, both theoretically and practically motivated, but they all have these difficulties in common. Consider the example of RSA cryptanalysis, where we are given an integer n which is the product of two large prime numbers a and b, and we need to factor n into its factors a and b. This can be achieved by attempting (according to the sieve of Eratosthenes) to divide n by every prime integer between 2 and √n, and hence it is a special kind of a search problem in itself. Several efforts in the past aimed to translate various encryption and hashing schemes into Boolean satisfiability (SAT). The SAT problem is a computationally intractable (NP-hard) problem but relatively efficient SAT-Solvers are built having computational complexity of 2^k (1-∈), where 0< ∈ <1 and thus can prune the search space significantly. Guided by the above concepts, we propose herein a scheme that can encrypt a message by using a ‘big’ Boolean function, which produces an equation that cannot be solved by the conventional SAT-Solvers and leads to a dramatic increase in the search space from 2^n to 〖〖(2〗^(2^m ))〗^n in the worst case. Logical cryptanalysis shows that the proposed scheme is very hard to break, indeed. To the best of our knowledge, the adversary cannot reduce or prune the search space (except for shortening the task needed at every node), and is forced to traverse the whole search space. He might arrive at several candidate solutions, and has to search for clues as to which of them is the correct solution.

miRNAs play vital regulatory roles in different plant developmental stages and in plant response to biotic and abiotic stresses. However, information is limited on the miRNA regulatory mechanism to methyl jasmonate (MeJA). In this study, we used the microRNAome profile to illustrate the relevant regulatory mechanisms of Euphorbia kansui in response to methyl jasmonate (MeJA) through Illumina RNA-Seq. As a result, we identified 875 miRNAs corresponding to 11,277 target mRNAs, among them, 168 known miRNA families representing 6019 target mRNAs sequences were obtained. 452 miRNA-mRNA pairs presented an anti-correlationship (Cor < −0.50 and p-value of correlation ≤ 0.05). The miRNA with a fold change ≥ 2 and a p (p-Value) < 0.05 in pairwise comparison were identified as significant differentially expressed miRNAs (DEMs). The DEMs in MeJA treatment of 0, 24, 36 and 48 h were compared by using Short Time Expression Miner (STEM) cluster and 4 significant gene profiles (p-value ≤ 0.02) were identified. Through the kyoto encyclopedia of genes and genomes (KEGG) pathway and gene ontology (GO) enrichment analysis on all miRNA targets, we identified 33 mRNAs in terpenoid biosynthesis, which were regulated by miRNAs under MeJA treatment, so the miRNA maybe involved in the response of E. kansui plant to exogenous MeJA and the results would provide very useful information on illustrating the regulatory mechanism of E. kansui and also provide an overall view of the miRNAs response to MeJA stress of a non-model plant.
Role of Serotonergic System in the Antidepressant Actions of mGlu2/3 Receptor Antagonists: Similarity to Ketamine
Authors: Chaki Shigeyuki , Fukumoto Kenichi
Published: March 2019

Numerous studies have demonstrated the antidepressant effects of group II metabotropic glutamate (mGlu2/3) receptor antagonists in various rodent models. Importantly, it has been shown that the antidepressant effects of mGlu2/3 receptor antagonists in rodent models are similar to those of ketamine, which exerts rapid and long-lasting antidepressant effects in patients with major depressive disorders, including patients with treatment-resistant depression. In addition, the synaptic mechanisms underlying the effects of mGlu2/3 receptor antagonists are reported to be similar to those underlying the effects of ketamine. The roles of the serotonergic system in the antidepressant effects of mGlu2/3 receptor antagonists have recently been demonstrated. Moreover, it was investigated how mGlu2/3 receptor antagonists interact with the serotonergic system to exert antidepressant effects. Notably, the same neural mechanisms as those underlying the effects of ketamine may be involved in the antidepressant actions of the mGlu2/3 receptor antagonists. In this review, we shall summarize the antidepressant potential of mGlu2/3 receptor antagonists and their mechanisms of action in comparison with those of ketamine. In particular, we shall focus on the roles of the serotonergic system in the antidepressant actions of mGlu2/3 receptor antagonists.
