Phosphorus, Sulfur and Cobalt Fertilization Effect on Yield and Quality of Soybean (Glycine max L. Merrill) in Acidic Soil of Northeast India

Soybean production on acidic soils of northeast India is often constrained by inadequate availability of phosphorus (P), sulfur (S) and cobalt (Co). To ascertain their individual and synergistic effects on growth, yield and quality of soybean, we conducted a field experiment on an acid alfisol (pH 4.5), with 12 treatments consisting of three levels of P (30, 60 and 90 kg P 2 O 5 ha -1 ), two levels of S (15 and 30 kg S ha -1 ) and two levels of Co (1 and 2 kg Co ha -1 ) application in factorial combination. In general, growth and yield parameters of soybean responded positively to higher doses of P, S and Co applications, with the response to P fertilization being the best. Higher doses of P also improved seed protein content of soybean. Based on the results of this study, we conclude that 60 kg P 2 O 5 ha -1 along with 15 kg S and 1 kg Co is advisable for optimum growth, yield and quality of soybean on acid alfisols of northeast India.
Muslim youths' e-lifestyle and its impacts on well-being

In the lives of young people, particularly the students, the internet has become all-pervasive. Internet development has sparked debates on how the online activities and online behaviour of youths can affect their well-being. While the positive aspects of internet usage have the potential to learn and improve social relationships, overuse of the internet can lead to addiction, as well as online risks such as abuse, cyberbullying, and sexual exploitation. This research aims to examine the impact of e-lifestyle on wellness dimensions and the total well-being of Muslim youth in Malaysia. The data was collected through a survey of 255 Muslim respondents aged between 18 and 24 years and analysed using SmartPLS 3.0. The results indicate that the second-order construct of e-lifestyle has a significant effect on all wellness dimensions, while only social wellness has a significant effect on the total well-being of Muslim youth. Later, the future implications are discussed, and a conclusion is provided.
Finite-Time Bipartite Tracking Control for Double-Integrator Networked Systems With Cooperative and Antagonistic Interactions

This paper is concerned with bipartite tracking for double-integrator networked systems with signed communication graphs, where both cooperative and antagonistic interactions coexist. A finite-time bipartite tracking framework is established, where followers track either the state or the opposite state of a leader. Different from some conventional results with convergence over an infinite time horizon, the finite-time convergence in this paper is achieved in an accurate manner. Under structurally balanced signed graphs, an integral sliding mode based finite-time bipartite tracking controller is proposed. The construction of an integral sliding mode variable is to ensure that the system dynamics is driven onto a sliding surface in finite-time. On the sliding surface, neighbouring states are used together with the homogeneous technique to guarantee that bipartite tracking is achieved in finite-time. To further realize fixed-time bipartite tracking, a controller is designed by using the integral sliding mode and the bi-limit homogeneous concept. Finally, numerical examples are provided to demonstrate the effectiveness of the proposed controllers.
Knowledge, attitude, practices and behaviour study regarding COVID-19 amongst health care workers of armed forces in North-Western part of India

Background: A concerted effort has been made by the Government of India and the Armed Forces to train all health-care workers (HCWs) in various aspects of the prevention and management of COVID-19. This study was conducted to evaluate the efforts by assessing their knowledge, attitudes, practice, and behavior regarding COVID-19. Materials and Methods: A quick online survey, using a web portal and social media platform with a pretested questionnaire, was conducted. Responses were collected for 3 days and analyzed. Results: A total of 988 HCWs participated, including 61 (6.17%) specialist officers, 98 (9.91%) medical officers, 17 (1.72%) dental officers, 135 (13.66%) nursing officers, 518 (52.4%) paramedical staff, and 159 (16.09%) supporting staff. There was a high prevalence (>90%) of knowledge related to symptoms and transmission of the disease with no statistically significant difference in knowledge based on the category of HCW except for bleaching powder requirement (0.001) and chemoprophylaxis (0.001). The majority of the participants (>95%) agreed that lockdown, infection control programs, and repeated training of HCWs are good measures to control COVID-19 spread. Observing full precaution while handling personal protective equipment was the only practice which demonstrated a significant association with increasing qualification of the participant (P < 0.001). Conclusions: Levels of knowledge, positive attitude, and good practices are high among HCWs in the Armed Forces, however, feeling of anxiousness and worry prevail being frontline workers with maximum proximity toward patients. Aggressive, continuous, relevant target population-oriented information, education, and communication is the need of the hour, with structured and programmed interventions for positive mental health during course of the pandemic.
Effect of zinc application on the maize

The article presents the results of field experience in studying the effect of zinc-containing fertilizers on the growth and yield of maize. The experiment was carried out under typical loamy chernozem in the loess of the Left-Bank Forest-Steppe (Sumy region, Sumy oblast). The following plots were studied: 1) control; 2) pre-sowing treatment of corn seeds with Monozinc, 3) treatment of seeds with Monozinc + spraying in the phase of 3-5 leaves Nutrivant Plus (0.5 l/ha); 4) seed treatment with Monozinc + spraying Nutrivant Plus in the phase of 3‒5 leaves (0.5 l/ha) and 10-11 leaves (1 l/ha). Zn monocinc from «Compo» (Germany) and Nutrivant Plus grain from «ICL Fertilizers» (Israel) were used, a hybrid of corn was Inagua (FAO 210, France). An increasing of the leaf surface area, plant height, height of the main ear in maize and yield under zinc fertilizers application has been established. The height of the main ear in maize was at the level of 72‒78 cm, the application of fertilizers slightly increased this indicator. The zinc application clearly influenced on the increasing of maize yields, but their effectiveness more depended on weather conditions. Under stress, the application of Nutrivant gave a larger increasing of grain yield. The maize yield increased to 0.35 t/ha under Monozinc seed treatment and with foliar top dressing with a Nutrivant plus 0.73, two-time top dressing ‒ 0.97 t/ha. On average, over two years of research, the weight of 1000 seeds in the control was 301.1 g, in fertilized plots ‒ 303.8‒310.9 g. The weight of grain in the treatment 2 was 2.1 g, in the 3 ‒ 5.8 g and on the 4-th ‒ 9.7 g. Monozinc treatment of seeds leads to increased germination energy to 3.1 % (compared to control), field and laboratory germination to 3.3 and 3.0 %, respectively.
EMBODIED GREENHOUSE GAS EMISSIONS FOR TWO DIFFERENT TYPES OF TIRE TREAD MOLDS

In an assessment of the carbon footprint (CFP) of a tire product, embodied greenhouse gas (GHG) emissions of its tread mold are usually disregarded due to the absence of available information. This study presents embodied GHG emissions of a winter tire tread mold and evaluates its significance. We also provide a comparative study between two types of mold, namely the sector and the element mold, which are not different in terms of the tread forming in the production process, but subject to the customer’s utilization. The assessment was performed according to the international ISO/DIS 14067 standard, requirements, and guidelines for the quantification of the CFP of products. Required input data of the processes were collected and allocated based on a tread mold production plant located in Thailand. Direct GHG emissions and indirect emissions were calculated according to the 2006 IPCC guidelines. In other indirect processes, secondary data from process-based and input-output-based data were assigned to match the best site specificity, and closer fuel mix in upstream inputs. The results obtained in this study show that the embodied GHG emissions were 5,033.36 kg CO2e for the sector mold, whereas 53.73% additional emissions were found in the dataset using the element mold. The embodied emissions estimated for the aluminum input were found to significantly influence the mold CFP. Disregarding the embodied GHG emissions during the production of a single conventional tire could result in an underestimation of 0.03% for the sector type and 0.05% for the element type. Furthermore, appropriate lifetime utilization of the tread mold could increase the contribution of the tread mold CFP.
Basic problems of scientific research in psychology

The article discusses the “immersion” of scientific and professional activities (assessment, consulting and psychotherapy) of psychologists from four perspectives: methodological, institutional, social practice and ethical. In scientific research, the primary importance is attached to testable empirical psychological theory. In particular, it has been emphasized that professional practice only makes sense and is ethical if it is supported by the results of basic research conducted by research psychologists.
Event-Triggered Sliding Mode Control of Uncertain Switched Systems via Hybrid Quantized Feedback

This article is concerned with the sliding mode control (SMC) for stabilizing a switched linear system with external disturbances and uncertain nonlinearities. The state sampling is implemented by an event-triggered mechanism (ETM) and the sampled data are transmitted through a limited-bandwidth digital channel. The main challenge of such a work comes from the quantizer saturation and quantization error in the SMC design with finite-level quantization and the mismatched control caused by the switch and event-triggered sampling. To solve the above problem, we at first present an ETM and a limited-information-based SMC law. Then, a new discrete-time level-sets method is proposed to develop the dynamic quantization policy (DQP). If the disturbance bound is known, the DQP can avoid the quantizer saturation without the need of online detection. A switching law and quantization parameter conditions are provided to ensure the convergence of the state trajectory. At last, the result is generalized to the unknown bound of disturbance. The limited-information control problem of a single-link manipulator is taken as a potential application of the proposed method.
Innovative design of spur gear tooth with infill structure

The progress of additive manufacturing technology brings about many new questions and challenges. Additive manufacturing technology allows for designing machine elements with smaller mass, but at the same time with the same stiffness and stress loading capacity. By using additive manufacturing it is possible to produce gears in the form of shell shape with infill inside. This study is carried out as an attempt to answer the question which type of infill, and with how much density, is optimal for a spur gear tooth to ensure the best stiffness and stress loading capacity. An analysis is performed using numerical finite element method. Two new infill structures are proposed: triangular infill with five different densities and topology infill designed according to the already known results for 2D cantilever topology optimization, known as Michell structures. The von Mises stress, displacements and bending stiffness are analyzed for full body gear tooth and for shell body gear tooth with above mentioned types of infill structure.
Breakup Likelihood Following Hypothetical Sexual or Emotional Infidelity: Perceived Threat, Blame, and Forgiveness

Abstract Infidelity represents a major threat to relationships, often resulting in dissolution of couples. The process from infidelity to potential breakup was studied in 92 couples using questionnaires concerning hypothetical scenarios of sexual and emotional infidelity. Structural equation model analyses using couple data for both infidelity types suggest that the level of perceived threat to the relationship was the main predictor of likelihood of breakup for men and women. Following each type of imagined infidelity, this effect was partly mediated by forgiveness. For emotional infidelity, level of blame was associated with forgiveness and breakup. The effect of blame on breakup was fully mediated by keeping less distance. The mechanisms involved in these processes were highly similar for women and men.
Design Optimization of Conical Concrete Support Structure for Offshore Wind Turbine

Various types of support structures for offshore wind turbine have been developed, and concrete structures have attracted attention due to many advantages. Although many studies have been conducted on the design of the existing steel structures, information and research on the design of concrete support structures are insufficient. Therefore, in this paper, a structural analysis model of conical concrete support structure (CCSS) is established and design optimization is presented. A detailed performance evaluation and the design of prestressed concrete were performed under the marine conditions of Phase 1 test site of southwest offshore wind project in Korea. The fluid–soil–structure interaction (FSI) was applied using the added mass method and soil spring model to represent the effects of water and soil. With the result of quasi-static analysis, a post-tensioning design was implemented by applying prestressing steel, and CCSS showed sufficient rigidity. From the natural frequency analysis, CCSS has a dynamic structural stability, and, in response spectrum and time-history analyses, the CCSS was safe enough under the earthquake loads. The methods and conclusions of this study can provide a theoretical reference for the structural analysis and design of concrete support structures for offshore wind turbines.
Quality improvement and value addition of processed fish (Clarias gariepinus) using phenolic compounds in coffee pulp smoke.

The antioxidative and antimicrobial effects of coffee pulp were investigated against rancidity (lipid oxidation) and microbial growth on smoked fish samples. About thirty kilogram’s (wet weight) of catfish (Clarias gariepinus) were killed, gutted and immersed in 15% brine for a period of 4 minutes before smoking. The fishes were divided into three batches and exposed to three smoking sources (Electric cooker (Control), Dry coffee pulp smoke and firewood smoke) for about five hours at temperature range of 80 – 900C. The three smoked fish samples were then kept differently in high densed polythene bag and kept for twenty-one days. Significantly lower values than the control were obtained for Trimethylamine, Thiobabituric acid and Peroxide values in both Coffee and charcoal smoked fish samples. During the second week, a well pronounced antioxidative effect of coffee pulp was noticed both control and firewood smoked samples. Higher preference (Physical) was shown for coffee smoked sample, as coffee aroma characterized the sample when exposed to air. Mould growth was most delayed in the coffee smoked sample till about fifteen days of storage. Fillet cut from the Coffee and firewood smoked samples were still appreciable when tasted. No repulsive odour was detected in coffee smoked sample. Coffee pulp therefore has potential antioxidative effect on rancidity in smoked fish and could also be used to flavor smoked fish products.
DETERMINANTS OF PURCHASE INTENTION ATHYPERMARKETS

Retailing industry in Malaysia has been transformed from traditional retailing market to supermarket and hypermarket sector. Although a small scale retailing market is still continue to exist, the emergence of hypermarket received considerable attention among consumers in Malaysia as an alternative for better choices and quality.The hypermarket was introduced to Malaysians with the arrival of Carrefour in 1994. The aim of the study is to examine the relationships of price, product quality and interior atmospherics with customer purchase intention in Malaysia. Data were collected using questionnaires from patrons of well known hypermarkets such as Kota Bharu Mall, Aeon, Billion, Tesco, Mydin, Giant and Pantai Timur Hypermarket. A total of 417 valid questionnaires were analyzed using descriptive statistics and Pearson correlation. The findings revealed that all three independents variable were significantly and positively correlated with the dependent variable. Of the independent variables, product quality had the strongest correlation with purchase intention, followed by interior atmospherics and price. The results suggest that a slight change in the independent variables will influence customer purchase intention at hypermarkets.
COMPARATIVE STUDIES ON THE PHYSIOCHEMICAL PROPERTIES, PHENOLIC COMPOUNDS AND ANTIOXIDANT ACTIVITIES IN 13 JAPANESE PLUM CULTIVARS GROWN IN THE SUBTROPICAL REGION OF CHINA

The physiochemical parameters and antioxidant properties of plum cultivars, grown in subtropical regions of China are little known. However, in this comparative study, these properties of 6 landraces and 7 introduced cultivars showed evaluated. The major nonvolatile constituents were a significant difference among cultivars. Color parameter values were strongly influenced by cyanidin 3-Oglucoside and cyanidin 3-O-rutinoside. Remarkably high antioxidant activity, high total phenolic, and ascorbic acid contents were found in black or purple flesh genotypes. Catechinic acid, the most important phenolic acid in Japanese plum, together with vanillic acid, caffeic acid and syringic acid, accounted for > 96% of the total phenolic content. The total phenolics and ascorbic acid concentration revealed significant contributions to antioxidant capacity detected by α, α-diphenyl-β-picrylhydrazyl (DPPH), (r = 0.78**, 0.73**) and ferric reducing antioxidant power (FRAP) (r = 0.74**, 0.57*). Moreover, there was a clear correlation between the total phenolic compounds and the ascorbic acid content (r = 0.76**). Comparison of physicochemical characteristics and antioxidant profiles revealed that both introduced cultivars and landraces had good adaptability in the subtropical region.
Phoenix: Towards Ultra-Low Overhead, Recoverable, and Persistently Secure NVM

Emerging Non-Volatile Memories (NVMs) bring a unique challenge to the security community, namely persistent security. As NVM-based memories are expected to restore their data after recovery, the security metadata must be recovered as well. However, persisting all affected security metadata on each memory write would significantly degrade performance and exacerbate the write endurance problem. On the other hand, relying on an encryption counters recovery scheme would take hours to rebuild the integrity tree, and will not be sufficient to rebuild the Tree-of-Counters (ToC). Due to intermediate nodes dependencies it is not possible to recover this type of trees using the encryption counters. To ensure recoverability, all updates to the security metadata must be persisted, which can be tens of additional writes on each write. In this article, we propose Phoenix, a practical novel scheme which relies on elegantly reproducing the cache content before a crash, however with minimal overheads. Our evaluation results show that Phoenix reduces persisting security metadata overhead writes to 3.8 percent less than a write-back encrypted system without recovery, thus improving the NVM lifetime by 8x. Overall Phoenix performance is better than the baseline.
Assessing the dimensionality of three LMX instruments within a diverse cultural and linguistic context

Multiple versions of the Leader-member exchange (LMX) instruments are widely utilized for exploring the quality of exchange between the leader/supervisor and the employees in leadership studies. Despite widespread usage, validation studies outside the USA are scarce. The purpose of this study was to analyze the psychometric properties of three versions of LMX instruments in the South African context. The factor structure, validity, and reliability of the respective versions were explored. The sample comprised of employees from the private (3598) and public (2640) sectors, from 106 organizations, across three independent studies. A three-factor structure was reported for 11 and 12 item instruments, which is different from the original four factor structure. The unidimensional 7 item instrument reported exceptionally good fit. The results of this study are useful for leadership researchers within the South African context, as they can use the LMX instruments with confidence, but it raises a question about the common practice of using foreign developed instruments for research purposes without testing its transferability to that specific context.
Assessment of water quality parameters in grow out phase of brackish water fish Lates calcarifer (Seabass) in floating net cages

Cage culture is an alternative to inland and brakishwater farming, whereby existing water resources are used to increase fish and shell fish production and the fish are enclosed in a cage allowing the water to pass freely between the fish in the sea. The mesh retains the fish, making it easier to feed, observe and harvest them. The mesh also allows the water to pass freely between the fish and surrounding water resource, thus maintaining good water quality and removing wastes. The present studies were conducted in the closed bay near Suryalanka, Baptla, Guntur district. Prior to start of the experiment, the transported fish were acclimated with the sea environment by rearing them in hapa net for one week. Fish with an average initial weight of 351.72±1.05g were randomly stocked in the net cages at 6fish/ m3, 8fish /m3, 10fish /m3, 12 fish/ m3. Standard methods (APHA) used for analysis of water quality. All important water quality parameters was analysed for a period of 90 days with 15 days interval. The growth parameter of fishes from each net cage were estimated by taking the individual body length and weight at every 15 days of interval. This paper gives detailed information on water quality parameters such as water temperature, pH, dissolved oxygen, total alkalinity, nitrite, nitrate, ammonia in brackish water fish culture in floating net cages.
A Predator-Prey Model of Unemployment and W-shaped Recession in the COVID-19 Pandemic

The paper presents a predator-prey model which captures the interactions between unemployment rate and COVID-19 infection rate. The model shows that lockdown measures can effectively reduce the infection rate, but at the cost of higher unemployment rate. The solution of the system makes the case for an endemic equilibrium of COVID-19 infections, hence producing waves in the unemployment rate in the absence of widespread immunity and/or vaccination. Furthermore, we simulate the model, calibrating it for the US. The simulation shows the dramatic effects on unemployment and on overall economic activity produced by potential recurrent waves of COVID-19, leading to a series of W-shaped recessions that - in absence of adequate policy response - jeopardize the coming back to the normal trend in the medium run.
Effects of Different Treatment Methods on Seed Germination of Kiwifruit

In order to break the dormancy of kiwifruit seed, accelerate the process of seed germination, to understan the effects of different treatment methods on the germination of kiwifruit seeds. Different treatment methods were set up in this study. The results showed that GA3 soaked for 18h can make seeds break the dormancy; when only the filter paper is placed on the petri dish, the germination rate is the highest: the most suitable disinfection time is 10min. After dark conditions, the seed germination rate was 73.3%, which was much higher than that under non-dark conditions. In certain range, the higher the concentration of GA3, the higher the germination rate of kiwifruit seeds.
