Authors: Varela-Giraldo Elizabeth , Úsuga-Suárez Alexandra , Duque-Cortés Juan E , Gómez-Oquendo Jorge , Restrepo-Betancur Giovanni
Published: September 2020

Background: In artificial insemination, chicken egg yolk is added to bovine semen to protect it during the cryopreservation process, although it contains substances that can affect the microbiological quality and metabolism of sperm. Objective: To evaluate post-thaw quality of bovine cryopreserved semen added with centrifuged and non-centrifuged egg yolk, low-density lipoproteins (LDL), and trehalose (T). Methods: Ten ejaculates from five bulls were cryopreserved under the treatments T1: pure egg yolk (PEY) at 20% v/v, T2: centrifuged egg yolk (CEY) at 20% v/v, T3: LDL at 8% v/v, T4: T at 100 mM, and T5: T at 100 mM plus LDL at 8% v/v (TLDL). Spermatic motility and kinetics, functional membrane integrity (FMI), structural membrane integrity (SMI), sperm vitality (SV) and abnormal morphology (AM) were assessed using the Sperm Class Analyzer (SCA®) system, hypoosmotic test (HOST), SYBR/PI probes, and eosin–nigrosin staining, respectively. A completely randomized design was used. Normal distribution of the variables was validated through the Kolmogórov– Smirnov test. A generalized linear model was used to determine sources of variation. Means were compared using the Tukey test. Results: Inclusion of CEY or LDL had a similar effect on sperm protection, and were superior for motility, kinetics and membrane integrity compared to the other treatments (p<0.05). CEY was superior for progressive motility (p<0.05). The cryoprotective action of LDL was similar to TLDL for motility and kinetics, SMI, SV, and AM (p<0.05). Inclusion of PEY and T resulted in the lowest semen quality (p<0.05). The use of T resulted in a reduction in FMI and SMI (p<0.05). No differences in AM between treatments were found (p>0.05). Conclusions: Egg yolk can be replaced by centrifuged egg yolk or low-density lipoproteins in the freezing extender used for bovine semen used in artificial insemination.

Published: September 2020

Ulcerative colitis (UC) is a major type of inflammatory bowel disease (IBD) and significantly impacts patient quality of life. Previous research revealed that the guanylate cyclase-C (GC-C) signaling pathway is associated with the severity of UC. We aimed to investigate the effect of the GC-C agonist, guanylin (Gn), on inflammatory injury in mice with colitis. An experimental UC model was established in Balb/c mice. Mesalamine served as a positive control. The Gn overexpression vector was administered once per day for 1 week. Intestinal permeability of the mice was measured using fluorescein isothiocyanate-dextran after the treatment. Histopathologic grading was estimated to assess the inflammatory injury of the colon. The expression level of crucial mediators of the GC-C signaling pathway (Gn, Ugn and GC-C) and tight junction proteins (occludin, claudin-1 and ZO-1) was measured in the colon. Additionally, the level of pro-inflammatory cytokines (IL-8 and TNF-α) in serum was measured. After injecting the UC mice with the Gn overexpression vector, the body weight increased, and the frequency of loose stools and bloody stools was decreased. Intestinal permeability and histopathologic score were significantly reduced (P<0.05). The expression level of GC-C, Gn, Ugn, claudin-1 and ZO-1 was significantly increased (P<0.05). The level of IL-8 and TNF-α in the serum was significantly decreased (P<0.01). Therefore, the application of Gn overexpression vector can ameliorate the intestinal inflammatory injury and repair the mucosal barrier in colitis mice, which further suggests the clinical therapeutic potential of GC-C agonists in IBD.

A Comparative Study of the Interpretation of Prophet Jesus' Verses Based on the Interpretation of Judge Numan and Al-Bahrani
Authors: Dizajy Vida , Aram Mohammadreza
Published: September 2020

The Book of Basis of Interpretation by Judge Numan is one of the most important Ismaili books that expresses its interpretative views on many verses. This study seeks to answer the important question of how do Judges Numan's interpretations coincide with the narrations of Allameh al-Bahrani in relation to the verses of Jesus (A.s)? This research is the documentary-analytical method and seeks to analyze the verses concerning Jesus (PBUH) in two books: The Basis of Interpretation and "Al-Burhan in the Interpretation of the Qur'an", the aspects of these two views being shared and differentiated. Explain and, through it, examine and criticize Judge Numan's intellectual foundations. The findings of this research show that Judge Numan, in his commentary and especially in his interpretations, has used his mental aptitudes more than he has expressed in a humorous way, except in very rare cases that he has not used the Ahlul-Bayt (A.S) narrations. Is and does not refer to its sources of interpretation. But an evaluation of the traditions in the book of Alburhan shows that more than half of all traditions are weak and less than a quarter of the relevant traditions are reliable. In this way, the narrations that Numan quotes from Alburhan cannot be cited. Despite Judge Numan's intellectual concessions to the issue of interpretation, there are serious drawbacks and ambiguities in his view that we will examine and critique in this article.

Published: September 2020

The Venturi tube measures the fluid’s flowrate by use of an obstruction in the flow path. As a tool to understand the fundamental principles of Chemical Engineering, an experimental device for flow measurement integrating a Venturi tube was developed in the course of the Chemical Engineering Projects I from the Federal University of Lavras. The system was constructed with materials of low-cost and easy access. The experimental results for the flow and pressure drop were compared with theorical values and with additional data obtained by the use of a numerical and computational method (CFD). The discharge coefficient was 0.680 ± 0.018 [-], an intermediate value of those found in the literature for orifice plate and flow nozzle meters. The numerical method was successfully able to predict the pressure drop in the system.

EVALUASI DAN OPTIMASI EFISIENSI ENERGI SISTEM CHILLER DENGAN PROSES DESCALING
Authors: Nuriyadi M. , Margana Ade S.
Published: September 2020

Chiller system consumes most energy (around 50%) of the electrical energy in a building. To reduce the use of energy, it is necessary to evaluate the use of energy and identify opportunities for energy savings and recommendations for increasing efficiency. The evaluation aims to ensure that a chiller system works and produces chilled water products as designed. The chiller system evaluation includes the evaluation of the chiller refrigeration system, power consumption, cooling capacity, as well as the evaluation of the piping system and pumps. Evaluation is carried out on the system before and after repairing/descaling on the chiller system.

The results of the evaluation and optimization of the chiller system are: the chilled water temperature output drops to 15oC, the cooling capacity of the chiller rises to 30 KW, the pressure of the condenser coolant pump rises to 0.58 bar. While the efficiency of the circulating pump system is 15.8%; efficiency of condenser cooling pump is 19.3% and distribution pump system efficiency is 14.1%.

The Europe 2020 programme is the European Union’s growth strategy for the coming decade and especially for new budget perspective 2014–2020. In a changing world, representatives of the EU want it to become a smart, sustainable, and inclusive economy. These three mutually reinforcing priorities should help the EU and its Member States deliver high levels of employment, productivity, and social cohesion. Concretely, the Union has set five ambitious objectives — on employment, innovation, education, social inclusion, and climate/energy — to be reached by 2020. Each Member State has adopted its own national targets in each of these areas. Concrete actions at EU and national levels underpin this strategy. The main objective of the research task is to give a comprehensive analysis of the knowledge-based economy from the regional perspective and the program Europe 2020. The particular main concern is the increase of the importance of the knowledge-based economy in the region, the Triple Helix model constructed advantages, programme Europe 2020 and financial instrument of this programme — Horizon 2020.

Każdy system polityczny jest podporządkowany osiągnięciu konkretnych celów w przestrzeni — czy to wewnętrznej, czy też międzynarodowej. Żaden system nie jest jednak w stanie wypełnić luki, jaką tworzy wadliwie zarządzane państwo. Przykład państw wyrosłych na fundamencie kultury anglosaskiej pozwala docenić wartość bezpieczeństwa wewnętrznego państwa. Anglia, jak też USA, na jego podstawie stworzyły model funkcjonowania w przestrzeni międzynarodowej. Jest on różny od europejskiego, podobnie jak odmienny jest tryb jego wprowadzania. I tak jak w przypadku oświecenia we Francji za zmianami szły idealistyczne wartości — równość, wolność i braterstwo — tak dla Amerykanów, jak również Brytyjczyków, liczyły się przesłanki pragmatyczne.

Published: September 2020

There have been cases of male transgender in Indonesia, yet there is a small study about them. Why do some biological females claim their identity as male transgender? How do they think of themselves as male transgender? The researcher study their life history and how they see themselves as male transgender. We have a total of six research subjects who acknowledged themselves as male transgender. This research used the in-depth interview for gathering data within six months. The results found that they became transgender based on their desire rather than coercion from others. Some of them were comfortable in coming out to their family, but most were considering how the society would judge them, and how they might bring shame to the family. Three research subjects were not able to show their true identity as transgender, because of several considerations, such as the fear of being ostracized by the society and the fear to be eliminated from their family. They took the gender role according to what would be accepted by the current environment. We conclude that the existence of transgender, who is biologically females to become males are very reluctant to open their sexual identity because of this reason.

Genomic selection (GS) can accelerate variety release by shortening the variety development phase when factors that influence prediction accuracies (PA) of genomic prediction (GP) models such as training set (TS) size and relationship with the breeding set (BS) are optimized beforehand. In this study, PAs for the resistance to fall armyworm (FAW) and maize weevil (MW) in a diverse tropical maize panel composed of 341 double haploid and inbred lines were estimated using 16 parametric, semi-parametric, and nonparametric algorithms with a 10-fold and 5 repetitions cross-validation strategy. For MW resistance, 126 lines that had both genotypic and phenotypic data were used as a TS (37% of the panel) and the remaining lines, with only genotypic data, as a BS. Regarding FAW damage resistance, two TS determination strategies, namely: random-based TS (RBTS) with increasing sizes (37, 63, 75, and 85%) and pedigree-based TS (PBTS) were used. For both MW and FAW resistance datasets with an RBTS of 37%, PAs achieved with phenotypic best linear unbiased predictors were at least as twice as higher than those realized with best linear unbiased estimators. The PAs achieved with BLUPs for MW resistance traits varied from 0.66 to 0.82. The PAs with BLUPs for FAW resistance datasets ranged from 0.694 to 0.714 for RBTS of 37%, and 0.843 to 0.844 for RBTS of 85%. The PAs with BLUPs for FAW resistance with PBTS were generally high varying from 0.83 to 0.86, except for the third dataset which had the largest TS (86.22% of the panel) with PAs ranging from 0.11 to 0.75. GP models showed generally similar predictive abilities for each trait while the TS designation was determinant. There was a highly positive correlation (R=0.92***) between TS size and PAs for the RBTS approach while, for the PBTS, these parameters were highly negatively correlated (R=-0.44***), indicating the importance of the relationship between the TS and the BS with the smallest TS (31%) achieving the highest PAs (0.86). This study paves the way towards the use of GS for maize resistance to insect pests in sub-Saharan Africa.
Mining Stack Overflow: a Recommender Systems-Based Model
Authors: Harrag Fouzi , Khamliche Mokdad
Published: September 2020

In software development, developers received bug reports that describe the software bug. Developers find the cause of bug through reviewing the code and reproducing the abnormal behavior that can be considered as tedious and time-consuming processes. The developers need an automated system that incorporates large domain knowledge and recommends a solution for those bugs to ease on developers rather than spending more manual efforts to fixing the bugs or waiting on Q&A websites for other users to reply to them. Stack Overflow is a popular question-answer site that is focusing on programming issues, thus we can benefit knowledge available in this rich platform. This paper, presents a survey covering the methods in the field of mining software repositories. We propose an architecture to build a recommender System using the learning to rank approach. Deep learning is used to construct a model that solve the problem of learning to rank using stack overflow data. Text mining techniques were invested to extract, evaluate and recommend the answers that have the best relevance with the solution of this bug report.
A Patient-Specific 3D+t Coronary Artery Motion Modeling Method Using a Hierarchical Deformation with Electrocardiogram.
Authors: Yoon Siyeop , Yoon Changhwan , Chun Eun ju , Lee Deukhee
Published: September 2020

Cardiovascular-related diseases are one of the leading causes of death worldwide. An understanding of heart movement based on images plays a vital role in assisting the procedure in the postoperative and postoperative processes. In particular, if the shape information can be provided in real-time using the electrocardiogram(ECG) signal using this information, the heart’s movement information can be used for cardiovascular analysis and imaging guides during surgery. In this paper, we propose creating a 3D+t cardiac coronary artery model that is rendered in real-time according to the ECG signal. Hierarchical cage-based deformation modeling is used to generate mesh deformation used during the procedure according to the ECG signal. We match the blood vessel’s lumen obtained from the ECG-gated 3D+t CT angiography taken at the multiple cardiac phases to derive the optimal deformation. Splines for 3D deformation control points were used to continuously represent the obtained deformation at the multi-view according to the ECG signal. To verify the proposed method, we compared the manually segmented lumen and results of the proposed method for eight patients. The average distance and dice coefficient between the two models was 0.543mm and 0.735, respectively. The required time for registration of the 3D coronary artery model is 23.53 seconds/model. rendering speed to derive the model according to the ECG signal after generating the 3D+t model is faster than 120 FPS.
Tapering, Tree Rings and Biomass Production of Pinus roxburghii (Sarg.): A Dendrochronological Study
Authors: Pandey Hari Prasad , Pokhrel Narayan Prasad
Published: September 2020

Distinguishable annual growth rings produce in Pinus roxburghii are an asset to find out the age of individual tree. This paper aimed to determine the age of P. roxburghii through coring samples and test the relationship with forest production. The biomass estimated, girths measured at two different sections and heights measured which allowed to determine the rate of tapering of the stand. The regression analysis was performed to test the relationship between various variables. The mean age of the P. roxburghii stand was found to be 23.97 (~24 years). The result showed the significant (p<0.05) positive correlation coefficient has been seen between age with girth at breast height, biomass, volume and carbon stock. However, no significant (p>0.05) correlation (r = 0.08) was found between age and height of the stand. In contrast, a correlation between diameter at breast height (DBH) was significant (p<0.05) and positive with volume, biomass, but no significant (p>0.05) correlation (r = 0.14) found between DBH and height of the stand. However, height has a significant (p<0.05) positive correlation with biomass. The mean biomass was 375 kg and mean annual increment (MAI) was 15 kg per tree. Rate of tapering of the studied stand predicted to be 3 cm diameter decreased with trunk height running at 100 cm from base to upward of P. roxburghii stand and vice versa. Result suggests that height-age relation is very weak whereas age, DBH, biomass and carbon has a significant correlation signifies that time-based forests' production and potential production estimation can be obtained in a relatively accurate way by utilizing the age of stand. The time-based forest production analysis is pioneer work in Nepal. The study affirms the tree ring count in P. roxburghii would be a credible and accurate method to determine the age of standing trees.
Bridging Macro and Micro Cosmos by a New Sight on “Photon Aging” – A Simple Approach for Explaining Diracs Large Numbers
Authors: Köhler J. Michael
Published: September 2020

The energy loss of photons due to the cosmological red shift is interpreted, here, as a periodical process of transferring electromagnetic field energy into the space. The transferred energy portions are independent on photon energy if this transfer occurs with their frequency. The amounts of periodically released energy are so small that the related ultra-long wave length photons have to be understood as perfectly delocalized. Thus, the described point of view bridges the quantum micro cosmos with the macro cosmos. It is proposed to regard this energy exchange as a typical property of universal time arrow and to interpret the “large numbers”, in particular the dimensionless reciprocal of product of Hubbles constant and Planck time as the fundamental parameter describing cosmic evolution.

This case study examined changes in body composition, resting metabolic rate (RMR), aerobic capacity, and daily physical activity in a patient who had ulcerative colitis who underwent ileal pouch‒anal anastomosis (IPAA) surgery. Body composition, RMR, and VO2 peak were assessed prior to, 4, 8, and 16 weeks after IPAA surgery. Daily physical activity data was extracted from a wrist-worn activity tracker preoperatively and 16 months postoperatively. At baseline, total body mass was 95.3 kg; body fat, 11.6 %; lean body mass, 81.1 kg; RMR, 2,416 kcal/d; and V̇O2peak, 42.7 mL/kg/min. All values decreased from baseline at 4 weeks postoperatively, body mass was 85.2 kg (-10.5%); body fat, 10.9% (-6.0%); lean body mass, 73.1 kg (-9.9%); RMR 2,210 kcal/d (-8.5%) and V̇O2peak, 25.5 mL/kg/min (-40.3%). At 16 weeks postoperatively, most parameters were near their baseline levels (within 1%-7%); exceptions were V̇O2peak, which was 20.4% below baseline, and RMR, which increased to nearly 20% above baseline. After the patient had an IPAA surgery, his total and lean body masses, RMR, and aerobic capacity were markedly decreased. Daily physical activity decreased postoperatively and likely contributed to the decreased aerobic capacity, which may take longer to recover compared to body composition and RMR parameters.

Piscirickettsia salmonis is an intracellular bacterial fish pathogen that causes piscirickettsiosis, a disease with numerous negative impacts in the Chilean salmon farming industry. Although transcriptomic studies of P. salmonis and its host have been performed, dual host-pathogen proteomic approaches during infection are still missing. Considering that gene expression not always corresponds with observed phenotype, and bacteriological culture studies inadequately reflect infection conditions, to improve the existing knowledge for the pathogenicity of P. salmonis we present here a global proteomic profiling of Salmon salar macrophage-like cell cultures infected with P. salmonis LF-89. The proteomic analyses identified several P. salmonis proteins from two temporally different stages of macrophages infection; some of them related to key functions for bacterial survival in other intracellular pathogens. Metabolic differences were observed in early-stage infection bacteria, compared to late-stage infections. Virulence factors related to membrane, LPS and surface component modifications, cell motility, toxins and secretion systems also varied between the infection stages. Pilus proteins, beta-hemolysin and the T6SS were characteristic of the early-infection stage, while fimbria, upregulation of 10 toxins or effector proteins, and the Dot/Icm T4SS were representative of the late-infection stage bacteria. Previously described virulence-related genes in P. salmonis plasmids were identified by proteomic assays during infection in SHK-1 cells, accompanied by an increase of mobile-related elements. By comparing the infected and un-infected proteome of SHK-1 cells, we observed changes in cellular and ROS homeostasis, innate immune response, microtubules and actin cytoskeleton organization and dynamics, alteration in phagosome components, iron transport and metabolism, and amino acids, nucleoside and nucleotide metabolism, together with an overall energy and ATP production alteration. Our global proteomic profiling and the current knowledge of the P. salmonis infection process allowed us to propose a model of the macrophage-P. salmonis interaction.

Liquefaction risk assessment is critical for the safety and economics of structures. As the soil strata of Ramsar area in north Iran is mostly composed of poorly graded clean sand and the ground water table is found at shallow depths, it is highly susceptible to liquefaction. In this study, a series of isotropic and anisotropic consolidated undrained triaxial tests are performed on reconstituted specimens of Ramsar sand to identify the liquefaction potential of the area. The specimens are consolidated isotropically to simulate the level ground condition, and anisotropically to simulate the soil condition on a slope and/ or under a structure. The various states of soil behavior are studied by preparing specimens at different initial relative densities and applying different levels of effective stress. The critical state soil mechanics approach for identifying the liquefaction susceptibility is adopted and the observed phenomena are further explained in relation to the micro-mechanical behavior. As only four among the 27 conducted tests did not exhibit liquefactive behavior, Ramsar sand can be qualified as strongly susceptible to liquefaction. Furthermore, it is observed that the pore pressure ratio is a good indication of the liquefaction susceptibility
A Critical Review of Shipbreaking Literature Reveals Shortcomings in Dimensions Considered for Sustainability
Authors: Rahman SM Mizanur
Published: September 2020

The shipbreaking industry is located predominantly in South Asian countries, and dismantles end-of-life ships to meet national steel demand. There are charges that this industry exploits local environmental, economic and social conditions to boost profits. The majority of this previous research often draws from a single disciplinary point of view that ignores or downplays complexities and trade-offs, precluding realistic policy improvement. Here we review 110 shipbreaking papers published in international peer reviewed journals that are indexed in SCOPUS, Science Direct and Google Scholar. We found that to date, shipbreaking research revolves around the coastal contamination of end-of-life ships waste over many other topics, and lacks critical interdisciplinary studies that explain trade-offs between environmental, social and economic factors that would better inform policy formulations for improvement of worker safety and environmental conditions. We propose a Life Cycle Sustainability assessment (LCSA) framework that could incorporate these trade-offs in a single analysis. We hope this review guides future studies towards more comprehensive sustainability measurement of shipbreaking activities.
Direct Laser Deposition Metal 3D Printing at Different Temperatures of the Printer’s Chamber: Computer Simulation
Authors: Hosseinzadeh Hamed
Published: September 2020

Metal 3D printing technology is a promising manufacturing method. The quality of the printed product can pass for mechanical application, if the anisotropy of the microstructure, imperfections, deformation, and residual stress of the printed sample could be lower than the appropriate level or if they are fully illuminated. Thermal stress is one of the significant reasons for deformation in the 3D printed samples. Thermal stresses are the direct consequence of the local temperature gradient. In this research, the effect of the temperature printer’s chamber (from room temperature to 900 C) was studied on thermal stress and subsequent total deformation in the printed sample. The printed sample is a six-layers-printed walk, which could be considered as a building block of other complex shapes and give us inside about deformation. The computational results show a meaningful reduction in thermal stress and deformation at the higher temperature of the printer’s chamber. The lower final deformation of the printed sample is an important subject, especially for samples with complex shapes.

Nisin is a 3.4 kDa antimicrobial peptide, produced by Lactococcus lactis (ATCC 11454). This bacteriocin can inhibit spores gemination and gram-positive bacteria development and has gained visibility in therapeutic use. The bacterial cellulose (CB) has been considered an ideal material and with high quality applied in food and medical-pharmaceutical inputs. Because of all this benefits, it is important to know the system proceeding of CB with nisin. Therefore, it was realize nisin release profile analysis of CBs was performed; analysis of the minimum inhibitory concentration (MIC) of nisin against Escherichia coli ATCC 25922, Pseudomonas aeuroginosa ATCC 9721 and Staphylococus aureus ATCC 10390; antimicrobial stability test, for 100 days at different temperatures of 4º, 25º and 37 ° C against microorganisms: S. aureus e L. sakei. The results show that nisin is released by the CB in 4 hours of contact with medium and the MIC of nisin is 78 µg/mL for S. aureus, doesn’t have gram-negative inhibition. It had stability until 100 days against L. sakei and 60 days for S. aureus. The system proved to be efficient and CB potentiated the antimicrobial action of nisin, acting as a selective barrier for other compounds present in the standard solution, serving as protection of the peptide at different temperatures. The CB loading system can be an ideal antimicrobial stability system for nisin.

Dynamic visualizations have been developed to exchange information that transforms over time across a broad range of professional and academic contexts. However, these visual tools may impose substantial demands on the learner’s cognitive resources that are very limited in current knowledge. Cognitive load theory has been used to improve learning from dynamic visualizations by providing certain design techniques to manage learner cognitive load without adding any oral/written explanations. This systematic review examined a series of experimental studies assessing the roles of these design techniques in learning tactical scenes of play through dynamic visualizations. Electronic databases PubMed and Google Scholar were used to search relevant articles. Eleven studies were eventually included for the systematic review based on the eligibility criteria. The present review revealed that adapting design techniques to the level of learners’ expertise, type of depicted knowledge, and level of content complexity is a crucial part of effective learning.

The purpose of this study was to examine the relationships between smartphone addiction of middle school students and smartphone usage types, depression, attention deficit hyperactivity disorder (ADHD), stress, interpersonal problems, and parenting attitude. This study was also performed with the aim of verifying the relationships among depression, ADHD, perceived stress, interpersonal problems, and parenting attitude, which are predictors of smartphone addiction. The subjects of this study were 487 local middle school students (234 males and 253 females). The measurement instruments used were the smartphone addiction scale, depression scale (PHQ-9), ADHD scale (K-ARS), perceived stress scale (PSS), interpersonal problem scale (KIIP-SC), and the parenting attitude scale. This study identified the relationships between the variables with correlation analysis and examined the predictors of smartphone addiction with hierarchical multiple regression analysis. According to the study results, the factors that influenced smartphone addiction were gender, stress, and interpersonal problems. In addition, when the confounding variables of smartphone addiction were controlled to examine the effects of smartphone usage types on smartphone addiction, social media use and music/videos were found to have a positively significant effect on smartphone addiction while study had a negatively significant effect. The order of the usage types with the highest influence on smartphone addiction was enjoying music/videos, social media use, and study. This suggests that selective intervention depending on the main smartphone usage type can be effective.
