Authors: Salehin Shahrbanoo , Simbar Masoumeh , Keshavarz Zohre , Nasiri Malihe 
Published: June 2020

Abstract

Introduction
In order to be effective in discussing high-risk sexual behaviors with adolescents, mothers need to be educated about their adolescent daughters’ sexual issues. As no detailed and exact knowledge on mothers’ educational needs concerning adolescent girls’ reproductive health is available, the current study was intended to investigate mothers’ educational needs concerning their adolescent daughters’ reproductive health.

Materials and methods
This research was a qualitative content analysis. Purposive sampling was performed to the saturation point. The samples included 26 mothers and 14 key informants. Semi-structured interviews were used for data collection. Data authenticity was verified based on Lincoln and Guba’s criteria and data analysis was conducted using conventional content analysis with MAXQDA10 software.

Findings
In this study, three themes and 13 main categories, each with a number of subcategories were extracted. The themes and main categories included: “appropriate educational content (reproductive health, sexual health, general health, psychological health, family health, social health and spiritual health)”, “characteristics of the educator (communicative skill, cognitive skill and moral competence)”, and “effective factors in learning (teaching method, learning conditions and environment, and the learner’s readiness)”.

Conclusions
The results demonstrated that mothers need to be informed about sexual, reproductive, general, psychological, family, social and spiritual health in adolescent girls. Consequently, the results can help the healthcare authorities to implement need-based programs and boost the effectiveness of education about adolescent girls’ reproductive health for mothers.
Variations in cricket players’ upper body dynamic balance across different levels of competition
Authors: Singla Deepika , Hussain M. Ejaz 
Published: June 2020

Abstract

Background
Balance ability has been associated with performance and injury prevention in athletes. Previous studies have investigated the differences in lower body dynamic balance abilities among male high school, collegiate and professional soccer players.

Objective
To investigate the differences on the Upper Quarter Y-Balance Test (UQYBT) in school, collegiate and employed cricket players.

Subjects
Dynamic balance data were collected for school (SCH; n = 22), collegiate (COL; n = 19) and employed (EMP; n = 15) cricket players of Jamia Millia Islamia, New Delhi, India using the UQYBT standardized protocol.

Methods
For the UQYBT, the participant reached with one hand in the medial, superolateral and inferolateral directions while maintaining three points of contact (other hand and both feet). The test was performed for both non-dominant and dominant hands.

Results
The SCH group had the least medial reach distance than the other two groups (p = 0.010). Also, SCH players tended to exhibit a lower composite reach score than the other groups, but this difference was not significant (p > 0.05). No bilateral differences were observed among the three groups in any of the reach directions.

Conclusions
Upper body dynamic balance performance varied with the competition level. This may indicate that athletes’ movement strategies may be different depending on the competition level and that normative values may need to be established for each competition level.
An Application of Wavelet Technique in Numerical Evaluation of Hankel Transforms

Published: June 2020

Abstract
This paper endeavors to formulate a stable and fast algorithm for the first time that is quite accurate and fast for numerical evaluation of the Hankel transform using wavelets which are usually difficult to solve analytically so it is required to obtain the approximate solution. So we have proposed an approach depending on separating the integrand

is expanded into wavelet series using wavelets orthonormal basis which are first derived and truncating the series at an optimal level or approximating

$rf(r)$

by a quadratic over the subinterval using the Filon quadrature philosophy. A good covenant between the obtained solution and some well-known results has been obtained. The solutions obtained by proposed wavelet method indicate that the approach is easy to implement and computationally very attractive. The novelty of our method is that we give error analysis for wavelet method for the first time in literature.
A function fitting method
Authors: Dachiraju Rajesh 
Published: June 2020

Abstract
In this article, we describe a function fitting method that has potential applications in machine learning and also prove relevant theorems.
The described function fitting method is a convex minimization problem which can be solved using a gradient descent algorithm.
We also provide qualitative analysis on fitness to data of this function fitting method.
The function fitting problem is also shown to be a solution of a linear, weak partial differential equation (PDE).
We describe a simple numerical solution using a gradient descent algorithm that converges uniformly to the actual solution.
As the functional of the minimization problem is a quadratic form, there also exists a numerical method using linear algebra.

Energetic Optimization Considering a Generalization of the Ecological Criterion in Traditional Simple-Cycle and Combined-Cycle Power Plants
Authors: Levario-Medina Sergio , Valencia-Ortega Gabriel , Barranco-Jiménez Marco Antonio 
Published: June 2020

Abstract
The fundamental issue in the energetic performance of power plants, working both as traditional fuel engines and as combined-cycle turbines (gas-steam), lies in quantifying the internal irreversibilities which are associated with the working substance operating in cycles. The purpose of several irreversible energy converter models is to find objective thermodynamic functions that determine operation modes for real thermal engines and at the same time study the trade-off between energy losses per cycle and the useful energy. As those objective functions, we focus our attention on a generalization of the so-called ecological function in terms of an ϵ parameter that depends on the particular heat transfer law used in the irreversible heat engine model. In this work, we mathematically describe the configuration space of an irreversible Curzon–Ahlborn type model. The above allows to determine the optimal relations between the model parameters so that a power plant operates in physically accessible regions, taking into account internal irreversibilities, introduced in two different ways (additively and multiplicatively). In addition, we establish the conditions that the ϵ parameter must fulfill for the energy converter to work in an optimal region between maximum power output and maximum efficiency points.
On historical language contact in English and its types: state of the art and new directions
Authors: Lavidas Nikolaos , Bergs Alexander 
Published: June 2020

AbstractThis article presents the state of the art of current research on the different types of language contact in early English. The article’s main aim is to show what kinds of phenomena have been investigated until now as possible areas of transfer/borrowing from other languages. We examine the main contact scenarios in Old and Middle English, which involve Latin, Celtic, French and Old Norse. We locate unanswered questions and underexamined hypotheses of historical language contact. We argue that the articles of the Special Collection on Language Contact in the History of English open new directions in the way we can investigate the role of early language contact in the development of English. New methodologies of research, the role of bilingualism in language change but also of the written types of contact, and the various domains of change in grammar, lexicon, and pragmatics offer insights into old and new hypotheses on scenarios of language contact.

Abstract
Albinism is the absence of pigmentation or coloration and is rarely found in nature. In this study we examined photos and videos obtained by cameras traps in the Legado das Águas Reserve. In the images, we identified two albino lowland tapirs. The results highlight the necessity of understanding the genetic diversity of lowland tapir populations and the important role of the professional photography associated with scientific research.
Cauchy matrix and Liouville formula of quaternion impulsive dynamic equations on time scales
Authors: Li Zhien , Wang Chao 
Published: June 2020

Abstract
In this study, we obtain the scalar and matrix exponential functions through a series of quaternion-valued functions on time scales. A sufficient and necessary condition is established to guarantee that the induced matrix is real-valued for the complex adjoint matrix of a quaternion matrix. Moreover, the Cauchy matrices and Liouville formulas for the quaternion homogeneous and nonhomogeneous impulsive dynamic equations are given and proved. Based on it, the existence, uniqueness, and expressions of their solutions are also obtained, including their scalar and matrix forms. Since the quaternion algebra is noncommutative, many concepts and properties of the non-quaternion impulsive dynamic equations are ineffective, we provide several examples and counterexamples on various time scales to illustrate the effectiveness of our results.

If You Can Understand This Essay, Then You Have Moral Rights and Moral Duties
Authors: White Alan 
Published: June 2020

Abstract
Alan Gewirth’s work on moral and political philosophy attracted a great deal of attention between 1978 and 2000, but has received very little attention since then. This essay aims to revive interest in Gewirth’s work by providing a more direct and straightforward version of his core argument for objective moral rights and duties and clarifying how a Gewirthian moral and political theory can proceed beyond the conclusion of the core argument.
Decreased MiR-30a promotes TGF-β1-mediated arachnoid fibrosis in post-hemorrhagic hydrocephalus
Authors: Zhan Chaohong , Xiao Gelei , Zhang Xiangyang , Chen Xiaoyu , Zhang Zhiping , Liu Jingping 
Published: June 2020

Abstract

Background
Fibrosis in the ventricular system is closely associated with post-hemorrhagic hydrocephalus (PHH). It is characterized by an expansion of the cerebral ventricles due to CSF accumulation following intraventricular hemorrhage (IVH). The activation of transforming growth factor-β1 (TGF-β1) may be involved in thrombin-induced arachnoid fibrosis.

Methods
A rat model of PHH was established by injection of autologous non-anticoagulated blood from the right femoral artery into the lateral ventricles. Differential expression of miR-30a was detected in rat arachnoid cells by RNA sequencing. AP-1, c-Fos, and TRAF3IP2 were knocked down in primary arachnoid cells, and the degree of arachnoid fibrosis was assessed.

Results
Decreased expression of miR-30a and increased expression of TRAF3IP2, TGF-β1, and α-SMA were detected in the arachnoid cells of PHH rat. Besides, overexpression of miR-30a targets TRAF3IP2 mRNA 3′UTR and inhibits the expression of TRAF3IP2, TGF-β1, and α-SMA in the primary arachnoid cells. Furthermore, TRAF3IP2 activates AP-1 to promote arachnoid fibrosis. The content of type I collagen in the primary arachnoid cells was reduced after the silencing of AP-1 and TRAF3IP2.

Conclusions
This study identified a miR-30a-regulated mechanism of arachnoid fibrosis, suggesting a previously unrecognized contribution of miR-30a to the pathogenesis of fibrosis in the ventricular system. These results might provide a new target for the clinical diagnosis and treatment of PHH.

Abstract
Oxidative stress, abnormal fatty acid metabolism, and impaired gut microbiota play a serious role in the pathology of autism. The use of dietary supplements to improve the core symptoms of autism is a common therapeutic strategy. The present study analyzed the effects of oral supplementation with Novavit, a multi-ingredient supplement, on ameliorating oxidative stress and impaired lipid metabolism in a propionic acid (PPA)-induced rodent model of autism. Male western albino rats were divided into three groups. The first group is the control, the second group was given an oral neurotoxic dose of PPA (250 mg/kg body weight/day) for 3 days and then received buffered saline until the end of the experiment. The third group received Novavit (70 mg/kg body weight/day for 30 days after the 3-day PPA treatment). Markers of oxidative stress and impaired fatty acid metabolism were measured in brain homogenates obtained from each group. Novavit modulation of the gut microbiota was also evaluated. While PPA induced significant increases in lipid peroxides and 5-lipoxygenase, together with significantly decreased glutathione, and cyclooxygenase 2, oral supplementation with Novavit ameliorated PPA-induced oxidative stress and impaired fatty acid metabolism. Our results showed that the presence of multivitamins, coenzyme Q10, minerals, and colostrum, the major components of Novavit, protects against PPA-induced neurotoxicity.
A southern German use of prefield-eses: Evidence from the corpus and an experimental study
Authors: Fricke Lea 
Published: June 2020

AbstractThere is a use of the German third person neuter pronounesesin the prefield, known as prefield-eses, which is characterized by being neither referential, nor an argument of the verb. According to Speyer’s (2008, 2009) optimality theoretic prefield ranking, this should only occur if a sentence contains no alternative element eligible to be moved to the prefield. This paper investigates a so far unnoticed use ofesesin the prefield in combination with a demonstrative pronoundiesand a copula verbist, which will be referred to asEs ist dies-sentence. This construction is an instance of prefield-eses, but contravenes the expectations about the use of prefield-esespostulated by Speyer, sinceEs ist dies-sentences do contain a suitable candidate to fill the prefield, the demonstrative pronoundies. In a corpus study,Es ist dies-sentences are compared to a sample ofDies ist-sentences. According to the corpus data,Es ist diesoccurs predominantly in southern dialects. Significant differences between the two samples concern 1) the distance to the antecedent ofdiesand 2) the type of content of the sentence. An online rating study, that compared acceptability judgments ofEs ist dies-sentences between speakers from different regions, confirmed thatEs ist dies-sentences are a phenomenon of southern dialects. In the light of these results, a modification of Speyer’s (2008, 2009) Stochastic OT model is proposed.
Partial Range of Motion Resistance Training: A Feasible Bodybuilding Training Regiment for Local or Regional Muscle Hypertrophy?
Authors: Newmire Daniel E. , Willoughby Darryn S. 
Published: June 2020

ABSTRACT
Bodybuilding is defined as an active lifestyle and competitive interest in body aesthetics and muscularity acquired through resistance training. The overall goal in these cosmetically assessed competitions is to display the human physique in a muscularly proportionate and symmetrical manner. Bodybuilding training falls within the hypertrophic oriented goals and recommendations. However, a resistance training modality known as optimal muscle length-specificity training or partial range of motion (pROM) has been recently investigated and has shown some similar hypertrophic outcomes compared to the standard full range of motion (fROM) resistance training. Additionally, there is some work suggesting pROM may have some benefit in local or regional muscular hypertrophy, which may benefit bodybuilding competitors allowing a muscle group focused stimulus. This may be beneficial for competitors who desire to give more attention to underdeveloped muscle groups to create better proportion and symmetry. There are positive yet not definitive results from investigations of pROM on hypertrophy. More research is needed to assess the validity of this mode of training within this population. Bodybuilding is a competition that judges a physique based on proportionate and symmetrical muscularity. The resistance training modality pROM may have benefits for this population.
Before Watson and Crick in 1953 Came Friedrich Miescher in 1869

Published: June 2020

AbstractThe story of genetics typically omits the original discovery of the molecular nature of DNA: Friedrich Miescher's 1869 discovery of the substance he christened “nuclein”. The article explains how he came...In 1869, the young Swiss biochemist Friedrich Miescher discovered the molecule we now refer to as DNA, developing techniques for its extraction. In this paper we explain why his name is all but forgotten, and his role in the history of genetics is mostly overlooked. We focus on the role of national rivalries and disciplinary turf wars in shaping historical memory, and on how the story we tell shapes our understanding of the science. We highlight that Miescher could just as correctly be portrayed as the person who understood the chemical nature of chromatin (before the term existed), and the first to suggest how stereochemistry might serve as the basis for the transmission of hereditary variation.
Multi-trait Genomic Selection Methods for Crop Improvement
Authors: Moeinizade Saba , Kusmec Aaron , Hu Guiping , Wang Lizhi , Schnable Patrick S 
Published: June 2020

Abstract
Plant breeders make selection decisions based on multiple traits, such as yield, plant height, flowering time, and disease resistance. A commonly used approach in multi-trait genomic selection is index selection, which assigns weights to different traits relative to their economic importance. However, classical index selection only optimizes genetic gain in the next generation, requires some experimentation to find weights that lead to desired outcomes, and has difficulty optimizing nonlinear breeding objectives. Multi-objective optimization has also been used to identify the Pareto frontier of selection decisions, which represents different trade-offs across multiple traits. We propose a new approach, which maximizes certain traits while keeping others within desirable ranges. Optimal selection decisions are made using a new version of the look-ahead selection (LAS) algorithm, which was recently proposed for single-trait genomic selection, and achieved superior performance with respect to other state-of-the-art selection methods. To demonstrate the effectiveness of the new method, a case study is developed using a realistic data set where our method is compared with conventional index selection. Results suggest that the multi-trait LAS is more effective at balancing multiple traits compared with index selection.
The Corpus of Spoken Lithuanian as a Research Source of Natural Usage
Authors: Kamandulytė-Merfeldienė Laura 
Published: June 2020

The article describes the Corpus of Spoken Lithuanian, its structure, compilation stages (collection of the recordings, transcription, and grammatical annotation), and the methodology of data collection and digitalization; in addition, it discusses the possibilities of corpus application in the research of natural language usage and the research, which has already been carried out, using the corpus data.
At present (2017), the corpus, which is freely accessible for internet users, contains 226,174 word forms. The users of the online corpus version can perform search of a word or a word form and obtain data on the frequency of the form in the whole corpus or its part as well as see grammatical information about it.
In 2016-2017, the Corpus of Spoken Lithuanian was supplemented by new data resulting from the implementation of the project “Contemporary Spoken Lithuanian: A Corpus-based Analysis of Grammar and Lexis” (LIP-085/2016) financed by the Research Council of Lithuania under the programme of the State Lithuanian Studies and Dissemination Programme for 2016–2024. The project will also create a new internet access, which will provide more possibilities for the users. The updated corpus consists of 256 conversations (383,587 words) produced by 1,086 speakers (659 females and 427 males), whose age ranges from 3 to 81 years. When developing the Corpus of Spoken Lithuanian, much attention was paid to its composition, i.e. the proportions of the corpus. In order to improve the universality and suitability of the corpus for a more varied analysis, the principle of a balanced corpus was maintained; therefore, several criteria were taken into consideration when collecting the data: the nature of spoken language (private vs public speech) and structure (dialogues vs polilogues), different communication situations (direct vs indirect (e.g. a telephone conversation), demographic indicators, and social relations among the interlocutors. Therefore, in 2018, users of the updated version of the corpus will be able to filter results according to different categories, such as gender, age, place and structure of the conversation, and perform a more detailed search. It is expected that when the users are provided with more possibilities to analyse corpus data on the internet, the amount of spoken language research will increase comprising different areas of lexis and grammar.
