Published: October 2020

Nowadays, biomedical data are generated exponentially, creating datasets for analysis with ultra-high dimensionality and complexity. An indicative example is emerging single-cell RNA-sequencing (scRNA-seq) technology, which isolates and measures individual cells. The analysis of scRNA-seq data consists of a major challenge because of its ultra-high dimensionality and complexity. Towards this direction, we study the generalization of the MRPV, a recently published ensemble classification algorithm, which combines multiple ultra-low dimensional random projected spaces with a voting scheme, while exposing its ability to enhance the performance of base classifiers. We empirically showed that we can design a reliable ensemble classification technique using random projected subspaces in an extremely small fixed number of dimensions, without following the restrictions of the classical random projection method. Therefore, the MPRV acquires the ability to efficiently and rapidly perform classification tasks even for data with extremely high dimensionality. Furthermore, through the experimental analysis in six scRNA-seq data, we provided evidence that the most critical advantage of MRPV is the dramatic reduction in data dimensionality that allows for the utilization of computational demanding classifiers that are considered as non-practical in real-life applications. The scalability, the simplicity, and the capabilities of our proposed framework render it as a tool-guide for single-cell RNA-seq data which are characterized by ultra-high dimensionality. MRPV is available on GitHub in MATLAB implementation.
Higher-Order Risk–Returns to Education
Authors: Henderson Daniel J. , Souto Anne-Charlotte , Wang Le
Published: October 2020

In the traditional human capital framework, education is often considered as an investment, rather than consumption, while consumption is not necessarily precluded. Whether education is an investment is empirically unclear and relatively under-explored. We shed light on this issue by estimating the risk–return trade-off in the context of education. If education is indeed an investment, risk could play an important role in individual educational decisions just as with risky assets. As portfolio theory predicts, there could be a trade-off between returns to education and risks concerning those returns: higher risks are generally associated with higher returns. We contribute to the literature by proposing various measures of risk based on the entire distribution of returns to education recovered by our nonparametric models. Our results confirm a trade-off between returns and variance. We also found statistically significant impacts for the higher moments: skewness and kurtosis. Interestingly, we found the relationship between mean returns and variance to be linear, and the relationship between expected returns and higher-moments (skewness and kurtosis) is non-linear.
Corrosion and Corrosion Protection of Additively Manufactured Aluminium Alloys—A Critical Review
Authors: Revilla Reynier , Verkens Donovan , Rubben Tim , De Graeve Iris
Published: October 2020

Metal additive manufacturing (MAM), also known as metal 3D printing, is a rapidly growing industry based on the fabrication of complex metal parts with improved functionalities. During MAM, metal parts are produced in a layer by layer fashion using 3D computer-aided design models. The advantages of using this technology include the reduction of materials waste, high efficiency for small production runs, near net shape manufacturing, ease of change or revision of versions of a product, support of lattice structures, and rapid prototyping. Numerous metals and alloys can nowadays be processed by additive manufacturing techniques. Among them, Al-based alloys are of great interest in the automotive and aeronautic industry due to their relatively high strength and stiffness to weight ratio, good wear and corrosion resistance, and recycling potential. The special conditions associated with the MAM processes are known to produce in these materials a fine microstructure with unique directional growth features far from equilibrium. This distinctive microstructure, together with other special features and microstructural defects originating from the additive manufacturing process, is known to greatly influence the corrosion behaviour of these materials. Several works have already been conducted in this direction. However, several issues concerning the corrosion and corrosion protection of these materials are still not well understood. This work reviews the main studies to date investigating the corrosion aspects of additively manufactured aluminium alloys. It also provides a summary and outlook of relevant directions to be explored in future research.

Published: October 2020

Liquid composite moulding (LCM) of plant fibre composites has gained much attention for the development of structural biobased composites. To produce quality composites, better understanding of the resin impregnation process and flow behaviour in plant fibre reinforcements is vital. By reviewing the literature, we aim to identify key plant fibre reinforcement-specific factors that influence, if not govern, the mould filling stage during LCM of plant fibre composites. In particular, the differences in structure (physical and biochemical) for plant and synthetic fibres, their semi-products (i.e., yarns and rovings), and their mats and textiles are shown to have a perceptible effect on their compaction, in-plane permeability, and processing via LCM. In addition to examining the effects of dual-scale flow, resin absorption, (subsequent) fibre swelling, capillarity, and time-dependent saturated and unsaturated permeability that are specific to plant fibre reinforcements, we also review the various models utilised to predict and simulate resin impregnation during LCM of plant fibre composites.

The present study assessed the retention forces corresponding to different telescopic systems used in removable prosthetic dentures. The telescopic systems were represented by Co–Cr alloy or zirconia-based primary crowns and Co–Cr secondary crowns. All crowns were manufactured using computer-aided design/computer-aided manufacturing technology (CAD/CAM). Two types of reference abutment teeth (upper canine and first upper molar) were selected in order to obtain the telescopic crowns and two taper angles—of 0° and 2°—were used for the design of the crowns. A number of 120 samples of telescopic crowns were obtained and subjected to mechanical tests, following a specific protocol, on a mechanical testing equipment. The retention of the telescopic systems was evaluated for different sets of cycles (up to 360), represented by movements that simulate the intraoral insertion and disinsertion of the telescopic systems. The present study highlights that the telescopic systems in which the primary crown is made of zirconia ceramics presents more advantages than those made of Co–Cr. All telescopic systems studied, highlighted that by modifying the taper angle from 0° to 2°, the retention forces have decreased, irrespective of the materials used for the fabrication of the primary crown, suggesting that by using a taper angle of 0°, which is known to be ideal, more efficient, and reliable prosthesis can be developed. Thus, even though the ceramic–metallic telescopic system exhibited the highest retention, all telescopic crowns evaluated registered values between 2–7 N, indicating that they are suitable for clinical use.

Published: October 2020

Marine actinobacteria are viewed as a promising source of enzymes with potential technological applications. They contribute to the turnover of complex biopolymers, such as pectin, lignocellulose, chitin, and keratin, being able to secrete a wide variety of extracellular enzymes. Among these, keratinases are a valuable alternative for recycling keratin-rich waste, which is generated in large quantities by the poultry industry. In this work, we explored the biocatalytic potential of 75 marine-derived actinobacterial strains, focusing mainly on the search for keratinases. A major part of the strains secreted industrially important enzymes, such as proteases, lipases, cellulases, amylases, and keratinases. Among these, we identified two streptomycete strains that presented great potential for recycling keratin wastes—Streptomyces sp. CHA1 and Streptomyces sp. G11C. Substrate concentration, incubation temperature, and, to a lesser extent, inoculum size were found to be important parameters that influenced the production of keratinolytic enzymes in both strains. In addition, proteomic analysis of culture broths from Streptomyces sp. G11C on turkey feathers showed a high abundance and diversity of peptidases, belonging mainly to the serine and metallo-superfamilies. Two proteases from families S08 and M06 were highly expressed. These results contributed to elucidate the mechanism of keratin degradation mediated by streptomycetes.

Published: October 2020

Tick-borne encephalitis (TBE) is a zoonotic disease that usually presents as a moderate febrile illness followed by severe encephalitis, and various neurological symptoms are observed depending on the distinct central nervous system (CNS) regions affected by the TBE virus (TBEV) infection. In Japan, TBE incidence is increasing and TBEV distributions are reported in wide areas, specifically in Hokkaido. However, an extensive epidemiological survey regarding TBEV has not been conducted yet. In this study, we conducted a retrospective study of the prevalence of antibodies against TBEV in patients with neurological disorders and healthy populations in a TBEV-endemic area in Hokkaido. Among 2000 patients, three patients with inflammatory diseases in the CNS had TBEV-specific IgM antibodies and neutralizing antibodies. The other four patients diagnosed clinically with other neurological diseases were positive for TBEV-specific IgG and neutralizing antibodies, indicating previous TBEV infection. In a total of 246 healthy residents in a TBEV-endemic region, one resident had TBEV-specific antibodies. These results demonstrated undiagnosed TBEV infections in Japan. Further surveys are required to reveal the actual epidemiological risk of TBE and to consider preventive measures, such as a vaccine program, for the control of TBE in Japan.
Thermo-Structural Evolution of the Val Malenco (Italy) Peridotite: A Petrological, Geochemical and Microstructural Study
Authors: Liu Wenlong , Cao Yi , Zhang Junfeng , Zhang Yanfei , Zong Keqing , Jin Zhenmin
Published: October 2020

The Val Malenco peridotite massif is one of the largest exposed ultramafic massifs in Alpine orogen. To better constrain its tectonic history, we have performed a comprehensive petro-structural and geochemical study. Our results show that the Val Malenco serpentinized peridotite recorded both pre-Alpine extension and Alpine convergence events. The pre-Alpine extension is recorded by microstructural and geochemical features preserved in clinopyroxene and olivine porphyroblasts, including partial melting and refertilisation, high-temperature (900–1000 °C) deformation and a cooling, and fluid-rock reaction. The following Alpine convergence in a supra-subduction zone setting is documented by subduction-related prograde metamorphism features preserved in the coarse-grained antigorite and olivine grains in the less-strained olivine-rich layers, and later low-temperature (<350 °C) serpentinization in the fine-grained antigorite in the more strained antigorite-rich layers. The strain shadow structure in the more strained antigorite-rich layer composed of dissolving clinopyroxene porphyroblast and the precipitated oriented diopside and olivine suggest dissolution and precipitation creep, while the consistency between the strain shadow structure and alternating less- and more-strained serpentinized domains highlights the increasing role of strain localization induced by the dissolution-precipitation creep with decreasing temperature during exhumation in Alpine convergence events.
Heterotrimeric G-Protein Signalers and RGSs in Aspergillus fumigatus
Authors: Park Hee-Soo , Kim Min-Ju , Yu Jae-Hyuk , Shin Kwang-Soo
Published: October 2020

The heterotrimeric G-protein (G-protein) signaling pathway is one of the most important signaling pathways that transmit external signals into the inside of the cell, triggering appropriate biological responses. The external signals are sensed by various G-protein-coupled receptors (GPCRs) and transmitted into G-proteins consisting of the α, β, and γ subunits. Regulators of G-protein signaling (RGSs) are the key controllers of G-protein signaling pathways. GPCRs, G-proteins, and RGSs are the primary upstream components of the G-protein signaling pathway, and they are highly conserved in most filamentous fungi, playing diverse roles in biological processes. Recent studies characterized the G-protein signaling components in the opportunistic pathogenic fungus Aspergillus fumigatus. In this review, we have summarized the characteristics and functions of GPCRs, G-proteins, and RGSs, and their regulatory roles in governing fungal growth, asexual development, germination, stress tolerance, and virulence in A. fumigatus.
Unveiling Trends in Cultural Participation: The Case of Slovakia
Authors: Šebová Miriam , Révészová Zuzana
Published: October 2020

This paper explores the trends in participation in a variety of cultural activities in Slovakia. Although the research on cultural participation has thrived and there have been plenty of empirical studies published about the consumption of cultural products in different countries, there is still a lack of comprehensive research from former post-communist countries. The paper aims to test the link between cultural participation and social and economic characteristics, which has previously been done in other international studies. The cluster analysis suggests four types of Slovak cultural participants—the heritage visitors, the omnivores, the popular genre visitors, and the inactive. The outcomes point to a strong relationship between cultural inactivity and heritage visits to socioeconomic status, while there is a weak relationship between highbrow cultural participation and the upper-class. The results challenge cultural policies to be adjusted for different groups of cultural participants with the objective of increasing the overall consumption of cultural goods in Slovakia.

Published: October 2020

Proper training methods may be used as an effective preventative measure for many of the musculoskeletal injuries sustained as a first responder that are inherent to the profession. The traditionally low fitness levels and poor exercise habits of city firefighters may predispose this population to an increased risk of chronic conditions, such as cardiovascular and metabolic disease. The purpose of this study was to analyze changes in the health and fitness parameters of professional firefighters across North Texas during a six-month training program. Twenty-two professional firefighters completed six months of group training, consisting of two training sessions per week. These individuals underwent a pre- and post-fitness testing protocol that consisted of body composition, range of motion, anaerobic power, muscular endurance, and cardiorespiratory fitness. Improvements (p < 0.05) in flexibility, anaerobic performance, fatigue index, muscular endurance, and aerobic fitness were found following the six-month training program. No differences in body composition or peak power were observed (p > 0.05). Six months of group exercise improves aerobic and anaerobic fitness, exercise tolerance, muscular endurance, and flexibility in firefighters.
A Brief History of the Major Rickettsioses in the Asia–Australia–Pacific Region: A Capstone Review for the Special Issue of TMID

Published: October 2020

The rickettsioses of the “Far East” or Asia–Australia–Pacific region include but are not limited to endemic typhus, scrub typhus, and more recently, tick typhus or spotted fever. These diseases embody the diversity of rickettsial disease worldwide and allow us to interconnect the various contributions to this special issue of Tropical Medicine and Infectious Disease. The impact of rickettsial diseases—particularly of scrub typhus—was substantial during the wars and “police actions” of the last 80 years. However, the post-World War II arrival of effective antibiotics reduced their impact, when recognized and adequately treated (chloramphenicol and tetracyclines). Presently, however, scrub typhus appears to be emerging and spreading into regions not previously reported. Better diagnostics, or higher population mobility, change in antimicrobial policies, even global warming, have been proposed as possible culprits of this phenomenon. Further, sporadic reports of possible antibiotic resistance have received the attention of clinicians and epidemiologists, raising interest in developing and testing novel diagnostics to facilitate medical diagnosis. We present a brief history of rickettsial diseases, their relative importance within the region, focusing on the so-called “tsutsugamushi triangle”, the past and present impact of these diseases within the region, and indicate how historically, these often-confused diseases were ingeniously distinguished from each another. Moreover, we will discuss the importance of DNA-sequencing efforts for Orientia tsutsugamushi, obtained from patient blood, vector chiggers, and rodent reservoirs, particularly for the dominant 56-kD type-specific antigen gene (tsa56), and whole-genome sequences, which are increasing our knowledge of the diversity of this unique agent. We explore and discuss the potential of sequencing and other effective tools to geographically trace rickettsial disease agents, and develop control strategies to better mitigate the rickettsioses.

Published: October 2020

In 2018–2020, the impact of anthropogenic activities on the ecological state and qualitative characteristics of the waters of the Alma River and its main inflow the Bodrak River was studied using a set of complementary methods: field – visual survey of the watercourse; laboratory – hydrochemical analysis of water samples; biological – bioassay (determining of water toxicity); calculation and analytical – study of space-time transformation of water quality, determination of the water pollution index and irrigation coefficients. Combination of the used methods made it possible to provide a consolidated assessment of the current ecological status of the Alma River ecosystem and to characterize it as a crisis leading to the transition to irreversible changes.
Statistical assessment of state and development level of agricultural territories of the Republic of Crimea
Authors:   Research Institute of Agriculture of Crimea, Popovich V.V.
Published: October 2020

The current and retrospective analysis of the development of agricultural territories using statistical data makes it possible not only to determine the level of agriculture current state in the regions and country as a whole and also identify existing problems and outline ways to solve them. In addition to economic and social indicators, environmental ones are very important nowadays and reflect the level of environmental protection. So in 2019, the current costs on environmental protection in individual administrative districts differed significantly and amounted to 0.77 rubles/ha in Dzhankoy district, 497.4 rubles/ha in Krasnogvardeisky district, and 138.2 rubles/ha in Saki district, and 114.1 rubles/ha in the Republic of Crimea. In general, in the Russian Federation, this figure was 421 rubles/ha. The data indicate insufficient investment in environmental protection in the Republic of Crimea as a whole and its regions in particular.

Published: October 2020

Optimization of planting dates and plant density for maize cultivation for green fodder is of particular importance under increased aridity in the Republic of Crimea. The aim of the research was to identify optimum planting dates and plant density for maize hybrids for green fodder harvested at the late milk stage under rain-fed conditions of the steppe zone of the Crimea. In the course of the experiment, we found that for the period from 2016 to 2019 yield of green fodder depended on the hydrothermal conditions of the year and plant density, as well as we observed the interaction of planting dates and conditions of the year. The optimum plant density was 70 thousand plants per hectare. On average, the yield of green fodder of early-ripening maize hybrid ‘Nur’ was 19.58 t/ha; medium early hybrid ‘Mashuk 220 MV’ – 19.25 t/ha, medium ripening hybrid ‘Mashuk 355 MV’ – 21.3 t/ha.

Assessment of the response of four spring barley varieties to the toxic effects of cadmium according to physiological, biochemical and morphometric parameters throughout the plant’s life cycle
Authors:   Russian Institute of Radiology and Agroecology, Dikarev A.V.
Published: October 2020

At our previous laboratory experiments, it was found that different spring barley varieties have some different reactions to the cadmium stress at the morphologic, cytogenetic and biochemical levels of plants organization. Thus, the goal of the current work was to assess the reliability of the previous results at full vegetation cycle of plant. The experiment was carried out on the loamy soil with four contrasting at its reactions to the cadmium barley varieties. Cadmium tolerant varieties demonstrated significantly higher values of productivity (e.g. straw, in this case, weighted four times more) and had a less amounts of Cd2+ accumulated at tissues (1.2–2.5 times) in contrast to sensitive ones, which, in fact, gave no harvest at Cd2+pollution at a rate of 50 mg/kg. The identified polymorphism of barley varieties in terms of resistance is maintained throughout the plant’s life cycle.

To obtain a high multiplication index (29.4) at the second stage of micropropagation, it is necessary to cultivate explants in flasks with MS medium supplemented with 1.0 mg/l kinetin.
GROUP BEHAVIORAL BIASES AFFECT FINANCIAL DECISIONS UNLIKE INDIVIDUAL BEHAVIORAL BIASES
Authors: de Brito Marcelo Henriques , do Valle Jardim Paula Esteban
Published: October 2020

This work presents a new approach to behavioral finance with a theoretical contribution by suggesting and discussing with examples a list of group behavioral biases along with established individual behavioral biases, bringing, hence, an additional outlook on how behavioral biases affect financial decisions. While individual behavioral biases are detected in individuals acting alone, group behavioral biases require the scrutiny of group behavior. This awareness may be particularly important to institutional investors, whose decisions basically stem from a committee or a group that will exhibit behavioral biases depending on how the group members interact between themselves when making a decision, which may include negotiation activities and not necessarily be related to personality or hierarchy. The focus on individual investors deciding on personal investments explain the need of work already developed in behavioral finance, which focus on individual behavioral biases, which may be a consequence from either cognitive errors or emotional biases. However, decisions from institutional investors basically stem from a committee or a group that will exhibit behavioral biases depending on how the group members interact between themselves when making a decision. To address the challenge of identifying causes and consequences for unexpected or unsuitable financial decision-making within a group, this work initially retrieves previous work on individual behavioral biases, linking emotional biases and cognitive errors to the “system 1” and “system 2” decision-making framework. Then, a conceptual contribution of this paper, which may be particularly relevant for institutional investors, is to explain with examples - after research and experience - which are the group behavioral biases and their impact upon financial decisions. Individual behavioral biases already acknowledged in other works on behavioral finance are contrasted in this work to the suggested group behavioral biases. Furthermore, this work suggests that there are two broad types of group behavioral biases: group dynamics biases and information-acceptance biases. Each broad type is subdivided into biases related to the structure of the group and biases related to how the group decision-making procedure occurs. Group dynamics biases related to the manner the group is structured are the following: kin bias (belonging bias), harmony bias, and competition bias. On the other hand, group dynamics biases may be sorted according to five different decision-making procedures, namely: herding, fad bias, Plato bias (denial bias), scarcity bias, and home bias.

ResearchAndMarkets wrote in their report on May 15, 2018, that up to 1.2 Trillion USD in 2017 of products are counterfeited goods. The report estimated this damage globally at 1.82 Trillion USD in 2020. This paper does not consider copyright infringement, digital piracy, counterfeiting or fraudulent documents, but rather examines the prevention of counterfeiting on a technological basis. The presence of counterfeit products on the European and US markets increase, the intervention of inspection bodies and authorities alone is obviously not sufficient, but consumers could make their contribution and improve the situation. In this paper, we research the possibility to reduce counterfeit products using machine learning-based technology. Image and text recognition, and classification based on machine learning have the potential to become the key technology in the fight against counterfeiting. Image recognition and classification of product information empowers the end customer to identify counterfeits accurately and efficiently by comparing them with trained models. The goal of this paper is to create an easy, simple, and elegant application, which empowers the end-users to identify counterfeit products and as such contribute to the fight against product piracy.

Published: October 2020

KOSENs not only try to increase students’ engineering abilities and literacy, which is the ability to use knowledge and skills, but also their competency, which we consider is the ability to apply knowledge and skills to any problem that might arise outside the walls of school. So the present study analyzes the relationship between a teacher’s evaluation of students’ self-assessment by “Daifuku-cho,” which is used for teacher-and-student interaction in PE class, and their competency improvement using PROG test scores. The result confirmed that students’ daily self-reflection and teachers’ feedback on them are important, and the outcome of their daily self-reflection can quantitatively show the growth in their competency. In particular, we report that the interaction between students and their teacher through the use of “Daifuku-cho” enhanced their learning and also that by comparing what the students wrote in “Daifukucho,” their grades and the results of PROG test, we suggest that the better students reflected themselves using “Daifuku-cho,” the more their competency developed.

Published: October 2020

Fake news is ‘false, often sensational, information disseminated under the guise of news reporting.’ The upsurge of technological advancement, especially social media, has paved the way for spreading fake news. The virtual realm spurs fake news as per the speed of air. Nowadays, fake news has been one of the social problems in the world along with Bangladesh. Self-seeker groups use fake news as an ‘atomic arsenal’ to disseminate their popular rhetoric with supersonic speed for fulfilling male purposes. Fake news is usually rampant during any crisis, elections, and even in campaigns. The hoaxers and fakers exploit the opportunity of the wavering psychology of the social media users, and fake news becomes ‘viral’ on social media, Facebook. Recently Bangladesh has faced an acute crisis of spreading fake news during the ‘Movement of Nirapod Sarak Chai, ‘National election in December 2018’ and very recent ‘need child’s head for Padma Bridge.’ This study titled “Spreading Fake News in the Virtual Realm in Bangladesh: Assessment of Impact” seeks the reasons for spreading fake news and its’ social impact in Bangladesh.

Authors: Morales Vanessa C. , Weaver Kathleen F. , Schnakers Caroline , Rosario Emily R.
Published: October 2020

Background: The incidence of traumatic brain injury (TBI) in the U.S. has been estimated at 1.7 million people each year and results in $60 billion in medical and productivity costs. A TBI can result in severe and potentially chronic cognitive and physical deficits. There has been an increased focus on the use of neurologic biomarkers for both monitoring progression and predicting clinical outcomes; however, the majority of the studies are focused on the acute phase.
Objective: In this study, the goal was to longitudinally characterize biochemical correlates of neural activity up to 2 years after injury and determine if these biomarkers correlate with functional outcomes.
Methods: Participants (n=13) with severe TBI as defined by the Glasgow Coma Scale (< 8) who are less than 1 year from the time of injury were included in this study. Blood samples and functional outcomes (DRS and RBANS) were collected upon enrollment and at 3, 6, 12, 18, and 24 months following enrollment.

La Corte Interamericana de Derechos Humanos es consciente de que los jueces y tribunales internos están sujetos al imperio de la ley y, obligados a aplicar las disposiciones vigentes en el ordenamiento jurídico. Pero cuando un Estado ha ratificado un tratado internacional como la Convención Americana, sus jueces están sometidos a su cumplimiento. El Reglamento de la Corte Interamericana de Derechos Humanos reformado parcialmente y renovado en vigor, en su artículo 2.3. define el término amicus curiae como «la persona ajena al litigio y al proceso que presenta a la Corte razonamientos en torno a los hechos contenidos en la demanda o formula consideraciones jurídicas sobre la materia del proceso, a través de un documento o de un alegato en audiencia». Por lo que tienen un importante valor para el fortalecimiento del sistema interamericano de protección de los derechos humanos, a través de reflexiones aportadas por miembros de la sociedad, que contribuyen al debate y amplían los elementos de juicio con que cuenta la Corte. En síntesis, el amicus curiae es un instrumento plausible y digno de ser explorado para tonificar el debate judicial ampliando los márgenes de deliberación, por medio de argumentos públicamente analizados, aportar a la defensa y la realización de los derechos humanos y contribuir a la elaboración de sentencias razonables y generadoras de un grado sustentable de consenso en la comunidad.

In recent years, there has been a growing need for natural fibre reinforced composite materials especially materials with good mechanical properties in order to substitute glass fibre based composite products to showcase a better engineering class for structural applications. Here the properties of jute fabric reinforced composite has been compared and analysed with e-glass fibre matte reinforced composite. The mercerized jute and e- glass fibre mats are treated with isophthalic resin. Charcoal powder has been used as a filler material constituting two percentage of the whole weight of entire composite. Isophthalic polyester resins offer substantially higher strength, better flexibility and chemical resistance. The properties of the jute composite and e-glass composite are determined by a series of tests such as Tensile, Flexural, Impact, Scanning Electron Microscopy (SEM) and Rate of Burning tests. The newly obtained composites provide a better usage for applications that require a much better physical strength and mechanical properties.

In the field of both atomic and thermal power-plant the Natural Draught Cooling Tower plays a very important role. The vulnerability of NDCT lies in its hyperbolic shell structure whereas the supporting columns play a pivotal role in load distribution and heat transfer mechanism. Throughout our study effort has been given to find out the behavior of Reinforced Concrete NDCT under static loading using two different types of support orientation. For enhanced accuracy finite element analysis method has been adopted. The geometry of NDCT has been created by strictly following IS code provisions. A detail analysis has been presented in terms of deflection, stress propagation and strain behavior under gravity load. In the final stage a comparison of response behavior of the hyperbolic shell and supporting columns has been prepared with various key components of stress strain behavior.

This examination points towards the advancement of an enhanced plan of a radiating blower comprising of different fan ribs, in light of execution appraisals looking like its inside parts. Different segments, for example, the outside cases and the turning fan ribs set in an assortment of working conditions, for example, fluctuating impeller speed and number of edges, are assessed mathematically and tentatively. Assessment depends on execution boundaries, including the delta and outlet pressures, stream rate, force, and intensity of the radial fan. The mathematical examination recommends that the blend of the different pivoting outline strategy and the standard k-ε disturbance model was suitable for recreation of the inside stream qualities and for power forecast. The mathematical outcomes were contrasted and tests under deliberately planned trial conditions. Plan and displaying of Impeller and packaging has been completed in CATIA V5R21 and then the Calculation was imported to Ansys 16.0. By differing the quantity of fan ribs, the exhibition fluctuates practically nothing. Nonetheless, the FC fan ribs display the best exhibition in regards to their stream rate reaction and are related with most reduced force. The weight at the exit is diminished as the stream rate is expanded. Among all the fans, the FC fan would yield the most noteworthy stream rate.

In the present work, the effect of process parameters on material removal rate during the machining of aluminium alloy (5086) with WEDM is studied. The four control parameter were selected i.e pulse on time (TON), pulse off time (TOFF), peak current (IP), and spark gap voltage (SV) to investigate their effects on material removal rate (MRR). Each control parameter had three levels. Total 27 experiments were done with a zinc coated brass wire of diameter 0.25 mm. Taguchi L9 orthogonal array technique was used for the experiment. ANOVA was used to find out the significance of control parameters and their contribution on MRR. It was found that maximum material removal rate was 41.52 mm3 /min which was due to high pulse on time and low pulse off time.
Reference Evapotranspiration Prediction for Smart Irrigation
Authors:   October University for Modern Sciences and Arts MSA,, Mohamed Samer I.
Published: October 2020

Irrigation is the most critical process for agriculture, but irrigation is the largest consumer of fresh water and causes the loss of large quantities because of the inaccuracy in crop water estimation. Our proposed system aims to improve irrigation management by estimating the amount of water needed by the crop accurately and reduces the number of meteorological parameters needed for such estimation. Detection of the reference crop evapotranspiration (ETo) is the most critical process in crop water estimation, that is considered through our proposed solution by implementing machine learning models using neural networks and linear regression to predict daily ETo using climate data like temperature, humidity, wind speed, and solar radiation. Comparing our system results with FAO-56 Penman-Monteith ET0 and cropwat8.0 software as benchmark, show that our proposed system is better than the linear regression model, in terms of determination coefficient (R^2)=.9677 and root mean square error(RMSE) =.1809, while the multiple linear regression model achieved determination coefficient (R^2)=.68 and root mean square error(RMSE) =3.01. Our system then used the predicted ETo and Crop coefficient (Kc) from FAO, to estimate crop evapotranspiration (ETc) for precision irrigation target.
