Effect of Genetic Variations in BMP 4 Gene (Exon 2 Plus Part Of Intron 2) on Infertility in Egyptian Buffalo Cows

Bone morphogenetic proteins (BMPs) are growth factors belonging to the transforming growth factor beta (TGF-β) superfamily. BMPs are intra-ovarian factors expressed in mammalian ovaries by oocytes, granulosa and theca cells. The present study was designed to isolate and detect polymorphism in BMP 4 (exon 2 plus part of intron 2) gene associated with infertility in Egyptian buffalo cows using PCR-RFLP and nucleotide sequencing techniques. PCR amplification of DNA from 35 Egyptian water buffalo (5 normal fertile, 14 anestrum and 16 repeat breeders) with 482 bp expected size was purified and sequenced. There was no variation in the sequence of amplified region between fertile and infertile group. PCR product was digested using Taqα1 and Hinf1 restriction enzymes gave one type of the restriction banding pattern with no polymorphism. Concluded that BMP 4 is highly evolutionarily conserved gene.

MYXOSPORIDIOSIS IN AFRICAN SHARPTOOTH CATFISH ( CLARIAS GARIEPINUS )

This study was conducted to screening for Myxobolus sp. infections in the brain of African sharptooth catfish (Clarias gariepinus). A total of 120 fish were collected over one year from Al fath center in Assiut Governorate. Smears of all samples were examined parasitologically, and polymerase chain reaction (PCR) was used to confirm selected positive samples. Examination revealed the presence of Myxobolus sp. in 57 (47.5%) of examined fish. Prevalence of infection was highest in winter and spring (56.7%) and became low in autumn (30%). The effect of body weight revealed that, the highest prevalence rate (52.9 %) was occurred in middle group (301400g). Female fish seems to be more sensitive to infection (48.5%) than male (46.2%). Morphological characters and measurements of mature spores were recorded. The amplified 18S rDNA gene fragment by using a specific primer for Myxosporean was (869bp).
Learning Assessment in Portugal: Research and Activity Theory

The author provides a global characterisation of research on the basis of six literature summaries covering practically all the research carried out in Portugal on learning assess‐ ment over the last three decades, by referring to some of the main findings. Most of the research was found to have used conceptions and/or actions and practices of the teacher as its item of analysis. Data was collected through surveys by means of interviews or ques‐ tionnaires. The researchers rarely obtained information from classroom settings enabling them to relate fundamental aspects (e.g. tasks, students, teachers, processes, results). Such is the framework in which the importance of considering the classroom an item of analysis and activity system is discussed so that it is possible to understand teacher evaluation practices, particularly the changes that may occur in the classroom in a more systemic, comprehensive and profound manner. This gives way to a discussion on the ontological, epistemological and methodological grounds related to activity theory, which are at the root of an alternative rationality to positivism and certain forms of constructivism. The ar‐ ticle ends with a set of reflections/recommendations for improving research in learning as‐ sessment and regarding the role activity theory can play in working towards improvement.
OUTCOME OF FECAL CONTINENCE AFTER PURE TRANS-ANAL PULL THROUGH VERSUS LAPAROSCOPIC ASSISTED IN MANAGEMENT OF HIRSCHSPRUNG’S DISEASE

Background: Several operative techniques have been developed for the treatment of Hirschsprung's disease (HD) in the past decades. One-stage trans-anal pull-through (TAPT) was first performed in 1998. Objectives: To evaluate fecal continence after laparoscopicassisted and trans-anal endo-rectal pull-through (TERPT) for recto-sigmoid Hirschsprung's disease (HSD). Patients and Methods: This prospective study was performed on 40 pediatric patients with Hirschsprung’s disease from July 2013 to July 2016 at Al-Azhar University Hospitals. The patients were divided into two equal groups: group (A) underwent laparoscopic assisted trans-anal endo-rectal pull-through, and group (B) underwent pure trans-anal endo-rectal pull-through (TERPT). Demographic, clinical data, preoperative investigations, operative records, postoperative outcome were studied. A continence evaluation questionnaire (CEQ, max score = 10) assessing frequency of motions, severity of staining, severity of perianal erosions, anal shape, and requirement for medications was used. Severity of staining was graded as none = 2, occasional = 1.5, often = 1, and always =0. Electromyogram (EMG) and magnetic resonance imaging (MRI) were also used in follow-up. Results: After one year of follow up , group A, continence score was normal in 10 (50%), good in 9 (45 %), and fair in 1 (5%); while group B, continence score was normal in 5 (25 %), good in 14 (70%), and fair in 1 (5%). However, staining/soiling in group A was present in 2(occasional staining); while group B, staining/soiling was present in 2(occasional staining). Statistically significant difference was found between groups according to continence score after 1month and 6 months, but no statistical significance clinically after 12 months. Conclusion: Laparoscopically assisted trans-anal endo-rectal pull through was less invasive and can provide a better clinical outcome compared with trans-anal endo-rectal pull through as regard fecal continence and stooling function.
Suspended Stripline Low-pass Filter Design for Wide Stopband Attenuation Applications

This paper involves the design of asymmetrical generalized Chebyshev low-pass filter realized with a suspended substrate stripline. The study presents the synthesis and design of an asymmetrical prototype with a degree of 11, the cut-off frequency of 2.5 GHz, better than 26 dB as passband return loss and a broad stopband rejection of 55 dB. The filter produces 11 transmission zeros (attenuation poles), one at infinity and 5 pairs located at finite frequencies offering better wide stopband attenuation performance as well as sharp selectivity. The filter is built based on suspended stripline structure (SSS) using aluminium as a cavity and with 2mm as a ground spacing. The filter measurements show a reasonable agreement has been achieved with the simulated response.An eleventh-order lowpass filter satisfying generalized Chebyshev response with asymmetrical topology, a wide stopband rejection and high selectivity has been presented. The filter has a total of 11 TZs, one is located at infinity and 5 pairs located at different finite frequencies contributing response improvements in both passband and stopband re- gions
IDENTIFIKASI MOLEKULER DAN STATUS KONSERVASI IKAN PARI HIU (RHINIDAE) YANG DIDARATKAN DI PULAU BANGKA

The high activity of catching Shark Ray (Rhinidae) have a big impact on the population and affect the balance of the marine ecosystem. This is supported by the characteristics of stingrays that have a lower reproductive ability, slower growth and higher risk of death. Lack of database information, relating to the Shark Ray can reduce oversight or regulations governing the production of the total catch. So the condition is feared impact on the survival of Shark Ray, especially in Bangka Belitung. One of the important databases that must be done is the accurate identification of fish species Shark Ray as a reference in determining the conservation status. The purpose of this research is to identify the molecular basis Shark Ray and the conservation status of the Shark Ray landed on Bangka Island. Shark Ray samples obtained from a source of potential landing in Bangka Island, namely PPN Sungailiat (Bangka Regency), TPI Ketapang (Pangkalpinang City) and TPI Kurau (Central Bangka Regency). The research method consists of three stages: collection of samples, the molecular identification (mtDNA Cytochrome Oxidase Subunit 1 / COI gene), phylogenetic analysis and conservation status of Shark Ray. The results of the COI gene nucleotide character matching were performed by using the BLAST program integrated into GenBank pages and showed that the three samples of Shark Rays were identified as Rhina Ancylostoma species (Bowmouth guitarfish, Shark Ray) with a rate of similarity of 100%. Based on data from the IUCN Red List, the species Rhina Ancylostoma in the category of Critically Endangered (CR) and based on the status of trade, at the 18th CoP meeting in Geneva, on August 2019, CITES has added Wedgefishes (Family Rhinidae) in Appendix II.
Malaria and Natural Disasters: Evidence Using GMM Approach

Natural disasters not only disrupt accessibility to education, health care, food supplies and clean water, but causes outbreak of diseases. These issues deteriorate the health conditions among the victims of disasters and reduce human capital accumulation that adversely affects the economic development of the country. This paper examines the impact of total disasters and floods on malaria incidences using panel data over the period 2008 to 2014 for 79 countries. For robustness check, we use two measures on each of these natural disasters; the number of occurrences and number of people affected by these disasters. Employing the system Generalized Method of Moment (GMM) model, the findings show that the occurrences and the number of people affected by total disasters and flood, significantly increases cases of malaria. Income and education negatively impact the incidences of malaria whereas urbanization and deforestation increase the rates of
Acetic acid mitigated salt stress by alleviating ionic and oxidative damages and regulating hormone metabolism in perennial ryegrass (Lolium perenne L.)

Organic chemical priming is an effective strategy in mitigating salt stress to plants. The objective of this study was to determine effects and associated mechanisms of acetic acid regulating plant tolerance to salt stress. Perennial ryegrass plants were pre-treated with 20 mM acetic acid and subsequently subjected to salt stress for 28 days. Salt stress caused increased endogenous acetic acid content with up-regulated expression of its key biosynthetic gene LpPDC1. Application of acetic acid effectively alleviated salt caused damage in perennial ryegrass. Acetic acid treatment increased K+ content and suppressed Na+ accumulation to maintain a higher K+/Na+ ratio in leaves exposed to salt stress. Plants treated with acetic acid also had significantly lower levels of ${\rm O}_2^- $ and H2O2, but higher SOD and CAT activities than those of the control after 21 days of salt stress. Acetic acid treatment also altered the plants endogenous phytohormone content with higher content of jasmonate (including JA, JA-ILe, and cis-OPDA), auxin (IAA), and cytokinins (CK, such as tZ, cZR, and iP), but lower content of abscisic acid (ABA) under salt stress conditions. Furthermore, expression of genes involved in JA, IAA, and CK biosynthesis and signaling pathways were up-regulated, while those involved in ABA were down-regulated by acetic acid treatment under salt stress. The results demonstrate that acetic acid could mitigate salt stress in perennial ryegrass by regulating K+ and Na+ balance, promoting ROS scavenging, and activating stress-protection hormone synthesis and signaling.
Machine Learning Classifiers Based Classification For IRIS Recognition

Classification is the most widely applied machine learning problem today, with implementations in face recognition, flower classification, clustering, and other fields. The goal of this paper is to organize and identify a set of data objects. The study employs K-nearest neighbors, decision tree (j48), and random forest algorithms, and then compares their performance using the IRIS dataset. The results of the comparison analysis showed that the K-nearest neighbors outperformed the other classifiers. Also, the random forest classifier worked better than the decision tree (j48). Finally, the best result obtained by this study is 100% and there is no error rate for the classifier that was obtained.

An Evaluation of the Shielding Effectiveness of Tellurite Glass with Composition 85TeO2-5Nb2O5-5ZnO-5Ag2O for Diagnostic Radiology Application

The metal oxide glasses have attracted huge interest as promising types of shielding materials to replace the toxic, heavy and costly conventional shielding materials. In this work, the physical and the shielding effectiveness of Tellurite glass sample (S1) contain host metal oxides (85TeO25Nb2O5-5ZnO-5Ag2O) were evaluated at photon energies range between 15keV and 1MeV.The shielding parameters of the proposed glass system such as linear attenuation coefficients, HVL, MFP, Zeff, and Neff were evaluated. The proposed samples showed a superior performance at the diagnostic energy range between 40 and 90 keV and a comparable shielding effectiveness above 90keV when compared with other commercial standard shielding materials.
FINITE ELEMENT IMPLEMENTATION OF GEOMETRICALLY NONLINEAR CONTACT

The OOFEM finite element software has been recently updated to include contact algorithms for small strain applications. In this work, we attempt to extend the contact algorithms to large strain problems. Reviewing the current code and comparing it with approaches encountered in literature, we arrive at a specific algorithmic solution and integrate it into the current code base. The current code is explained, the necessary extensions are derived and documented, and the algorithmic changes are described. Tests confirm the functionality and quadratic rate of convergence of the proposed implementation.
Post-Convergent Mediatization: Toward a Media Typology Beyond Web 2.0

In this article, I argue that the concept of convergence, as is still applied to media theory, has become an insufficient way for examining the current state and future of media phenomena. This is substantiated by the fact that digital media continue to exponentially percolate into human experience in ways that transcend mere integration. I contend that a recognition of post-convergence as a theoretical realization is crucial to future developments in media theory because it presumes that digital media are progressing toward a “digitization of life” in ways that are envisioned within the very logic of digitality. As post-convergence continues its way to become a theoretical realization, media theory should begin posing its questions about the digital not in terms of how traditional media and its attributes prevail in the digital, but of how digitality as an objective reality engenders experiences of the real requiring approaches that can only be formulated from the logic of post-convergence. From such theorization, I propose a working typology for conceptualizing the possible nature and direction of post-convergent media: hyper-mediation, bio-digitality, hyper-connection, and hyper-simulation.
CHARACTERIZATION OF TiO2, ZnO, AND TiO2/ZnO THIN FILMS PREPARED BY SOL-GEL METHOD

Nanostructured thin film has been extensively study because they exhibit better structural, optical, and electrical properties. Generally, the photocatalytic activity was relying on adapting condition of the material to be composited. These composite materials will be manipulated the particles size, crystallographic phase and morphology of the nanocrystallite according to condition of method preparation. Thin films of TiO2, ZnO, and TiO2/ZnO were deposited on microscope glass slides by sol gel dip coating technique. The titanium dioxide (TiO2) solution was obtained from titanium (IV) butoxide and butanol as the precursor, while zinc oxide (ZnO) solution was obtained from zinc acetate dehydrate and isopropanol as the precursor. Both of solution was ageing for 24 hours and different calcination temperatures used to calcined the thin films (400 oC, 500 oC, 600 oC). The thin films were characterized by X-ray Diffraction (XRD), and Atomic Force Microscopy (AFM). In this study, the effect of temperature show difference results of single layer and bilayer thin films. The result of XRD shows when the temperature increase, the thin films provide a good crystallization phase in which the structure of the diffraction peaks higher. From the AFM analysis, the surface roughness and the grain size increases as the temperature increase. Based on the characterization was carried out, the increase in temperature has influenced the distribution on the phase structure. The intensity of nanostructure thin films and also the smooth and compacted surface roughness were controlled by the temperature.

Heat stress in maize: characterization and phenotypic plasticity

The future challenge will be to produce more maize and other crops, in stressed environments. Two experiments were carried out during the 2015-2016 season at INTA Leales field, Tucumán, Argentina. The treatments included a factorial arrangement of two thermal environments (non-stress and heat stress) and 15 hybrids (Exp.1) and 6 maize inbred lines (Exp.2). The hybrids and inbred lines showed phenotypic variability in most of the evaluated traits for heat stress during critical period for kernel set. The tropical genotypes (HS9, HS10 and L3) were identified as tolerant, while genotypes with a temperate x tropical and temperate genetic background (HS13, HS14 and L5) were identified as the most susceptible. There was a grain yield reduction of 82% and 78% in H13 and L5, respectively when comparing the non-heat stress environment with heat-stress environment. Range in phenotypic plasticity was similar for hybrids and inbred lines, being the largest for trait such as, grain yield, kernel number, anthesis-silking interval, harvest index, and the smallest for traits such as kernel weight, ear diameter, prolificacy, aboveground biomass at physiological maturity, cumulative thermal time to silking and leaf greenness post stress on ear leaf. The outcomes from this research are promising for future heat-stress screening, in order to increase the selection efficiency in a breeding program. Abbreviations CP, critical period for kernel set; Exp.n, experiment n; fPARi, fraction of incident photosynthetically active radiation intercepted by the canopy; HS, single hybrids; HSI, heat susceptibility index; L, inbred lines; NSE, non-stress environment; SE, heat stress environment. Other abbreviations are listed and described in detail in Table 2 Heat stress in maize: characterization and phenotypic plasticity
Generative Adversarial Networks

Generative Adversarial Networks (GANs) have promoted a variety of applications in computer vision and natural language processing, among others, due to its generative model’s compelling ability to generate realistic examples plausibly drawn from an existing distribution of samples. GAN not only provides impressive performance on data generation-based tasks but also stimulates fertilization for privacy and security oriented research because of its game theoretic optimization strategy. Unfortunately, there are no comprehensive surveys on GAN in privacy and security, which motivates this survey to summarize systematically. The existing works are classified into proper categories based on privacy and security functions, and this survey conducts a comprehensive analysis of their advantages and drawbacks. Considering that GAN in privacy and security is still at a very initial stage and has imposed unique challenges that are yet to be well addressed, this article also sheds light on some potential privacy and security applications with GAN and elaborates on some future research directions.
Autologous Platelet Rich Fibrin as a potential antiperiopathogenic agent: An in- vitro study

Background: Lately, hard and soft tissue regeneration property of autologous platelet concentrates is gaining a lot of popularity in dental and allied fields. Along with intrinsic regenerative properties, platelets are hypothesized to release certain antimicrobial peptides. Aim of present study is to evaluate antimicrobial activity of platelet-rich fibrin (PRF) preparation against periodontal pathogenic bacteria. Methods: Subgingival plaque samples and blood samples from fifteen generalized chronic periodontitis patients were collected. Antimicrobial activity of PRF preparation against periodontal bacteria was assessed. Disc diffusion method and colorimetric analysis were employed to quantify the inhibitory effects. Results: PRF demonstrated clear zone of inhibition in disc diffusion method and showed minimum amount of turbidity confirmed by colorimetric analysis. This clearly indicates possible bactericidal activity against gram-negative periodontopathic bacteria. Conclusion: Apart from being excellent regenerative material, through its antibacterial effects, PRF can provide additional benefits at periodontal surgical sites.
Effect of Online Flipped Classroom on Students' Writing Development at Senior High School

Recent developments in technology and education have created an enormous array of opportunities in the field of language learning and teaching. From one side, modern technologies are promptly attracting new users, providing growing dimensions, and allowing more sophisticated uses. Form the other side, the students’ zeal toward utilizing mobile technologies in classroom brought the idea of examining these technologies in the context of Iran. To this end, this study investigated the effect of flipped classroom on Iranian EFL students' writing development at senior high school. A group of 48 K-10 male students were conveniently assigned into two groups. The students of the control group were taught writing using distance method just like a traditional classroom held online, while the students of experimental group were taught writing through online flipped method. The results using independent and paired sample t-test and ANCOVA revealed that the experimental group outperformed the control group in content, organization, and vocabulary areas.
