The influences of water quality on fish occurrences in Kuala Mai, Pahang River and Ulu Tembeling, Tembeling river, Pahang, Malaysia.

This study assessed the fish community structures and influences of water quality on fish occurrences in Pahang and Tembeling rivers, Pahang. Fish samplings and water quality measurements were conducted in Kuala Mai, Pahang River and Ulu Tembeling, Tembeling River from 12 and eight different sampling points, from October 2007 to September 2008, and August 2006 to August 2007, respectively. The fish diversity, richness and evenness indices were determined, while the water quality parameters were compared for both rivers. Multivariate analyses were then used to explore the effects of water physicochemical parameters on the fish occurrences. A total of 2,391 individuals were collected from this study, comprising of 20 families and 65 species of fish. Using the gill nets, cast nets and fishing rods, a total of 55 fish species from 17 families were recorded in Kuala Mai, Pahang River, compared to 47 species from 15 families in Ulu Tembeling, Tembeling River. There were significant differences (p < 0.05) for fish diversity (H and 1-D), but not for fish evenness (e) and richness (D) between both rivers. The mean water temperature, ammonia nitrogen and total suspended solids were significantly different (p < 0.05) in both rivers. Apart from the influences of pH, alkalinity and phosphate in both rivers, the results showed that the temperature, dissolved oxygen and conductivity were the major influencers on the fish occurrences in Nur Farhanim Mohd Sukeri, Zulkafli Abd. Rashid, Abdulwakil Olawale Saba, Muhammad Rasul Abdullah Halim and Mohammad Noor Azmai Amal 164 Pertanika J. Trop. Agric. Sc. 43 (2): 163 182 (2020) Kuala Mai, Pahang River, while ammonia nitrogen and total suspended solids in Ulu Tembeling, Tembeling River. Fish conservation and stock management efforts are urgently needed due to the decreasing number of near-threatened, endangered and critically endangered fish species in both rivers.
Social Media and Employment – Students' vs. Employers' Perspective

Recently, social media has become an integral part of different business activities. One of these activities is the recruitment and selection of employees. The paper presents the results of empirical research conducted among the students of the University of Mostar, Bosnia and Herzegovina (BH) and BH employers related to the use of social media in the process of recruitment and selection of new employees. The aim of the research is to find if there are similarities or/and differences in standpoints of students and employers concerning the use of social media in job finding and recruitment. The results show that most students and employers recognized social media as a valuable tool in the process of job finding, i.e., recruiting. However, both students and employers expressed reserve about data accuracy on social media. Students were resolute that their activities on social media should not affect their employment, while employers saw social media only as an additional tool in human resource management.
Geometric Sequential Learning Dynamics

In this letter, we introduce a novel dynamic model for predicting the exact strategies of the opponents without message exchange, namely geometric sequential learning dynamics (GSLD). The intuition is twofold; first, the utility function is widely modeled by arbitrary exponential varieties; second, the equidistant sampled exponential function comprises a geometric sequence. To validate GSLD, we model the exponential variety game (EVG) and prove its convergence by showing that it is a continuous quasi-concave game. The proposed scheme enables the construction of the exact individual utility function, which results in a faster convergence and a high utility value.
An oligarchy of NO-producing interneurons controls basal and evoked blood flow in the cortex

Changes in cortical neural activity are coupled to changes in local arterial diameter and blood flow. However, the neuronal types and the signaling mechanisms that control the basal diameter of cerebral arteries or their evoked dilations are not well understood. Using chronic two-photon microscopy, electrophysiology, chemogenetics, and pharmacology in awake, head-fixed mice, we dissected the cellular mechanisms controlling the basal diameter and evoked dilation in cortical arteries. We found that modulation of overall neural activity up or down caused corresponding increases or decreases in basal arterial diameter. Surprisingly, modulation of pyramidal neuron activity had minimal effects on basal or evoked arterial dilation. Instead, the neurally-mediated component of arterial dilation was largely regulated through nitric oxide released by neuronal nitric oxide synthase (nNOS)-expressing neurons, whose activity was not reflected in electrophysiological measures of population activity. Our results show that cortical hemodynamic signals are not controlled by the average activity of the neural population, but rather the activity of a small ‘oligarchy’ of neurons.
Electrically Small, Single-Substrate Huygens Dipole Rectenna for Ultracompact Wireless Power Transfer Applications

An electrically small, single-substrate Huygens dipole rectenna with exceptional physical and radiation performance characteristics is reported. A highly efficient rectifier circuit is seamlessly integrated with an ultrathin, electrically small, Huygens dipole antenna (HDA) on a single piece of Rogers 5880 substrate. It consists of two metamaterial-inspired near-field resonant parasitic (NFRP) elements, an Egyptian axe dipole (EAD) and a capacitively loaded loop (CLL) that are etched on the top and bottom metallization layers of the substrate, respectively. A printed receiving dipole is amalgamated tightly with the rectifier on the CLL layer. This ultracompact rectenna system has a large electromagnetic wave capture capability and achieves nearly complete conversion of the incident energy into dc power. The HDA prototype has a realized gain of 4.6 dBi and a half power beamwidth (HPBW) greater than 130°. The entire rectenna is electrically small with ka =0.98, is low cost and easy to fabricate, and has a measured 88% ac-to-dc conversion efficiency. The developed rectenna system is the ideal candidate for ultracompact far-field wireless power transfer (WPT) applications.
Optimal Scheduling of the Integrated Electricity and Natural Gas Systems Considering the Integrated Demand Response of Energy Hubs

Nowadays, integrated electricity and natural gas system (IENGS) stands as one of the most discussed topics among industry and academic sectors. The interdependency issues of electricity and natural gas may limit the operational flexibility of the IENGS and consequently prevent wind power integration. This article aims to solve the problem by incorporating the demand-side flexibility of energy hubs (EHs) into the scheduling of the IENGS. To fully exploit the demand-side flexibility, the detailed integrated demand response (IDR) model is developed for the EHs. Unlike the traditional demand response programs in which only elastic electricity demand is considered, both electricity demand and natural gas demand are considered flexible and controllable in the IDR. Moreover, the IDR is modeled as an optimization problem rather than a price-responsive load bid. The interactions between the EHs’ IDR model and the IENGS's scheduling model are achieved based on the two-level optimization framework. Then, the IDR-embedded scheduling of the IENGS is formulated as a complicated two-level mixed integer nonlinear programming (TL-MINLP) problem. A technique is proposed to solve the TL-MINLP problem efficiently to enable the IDR-embedded scheduling model to be used in engineering practice. Case study illustrates the benefits of the proposed IDR-embedded scheduling method.
Pedestrian Dead Reckoning With Wearable Sensors: A Systematic Review

Pedestrian Dead Reckoning (PDR) is the process of calculating one's current location by using the previously known position, and advancing that position over time using established or estimated speeds and trajectories (or alternatively stride lengths and directions). PDR plays an important role in modern life, including tracking locations of people and objects whenever GPS is not available. Self-contained PDR systems do not require an infrastructure, thus they can be used for rapid deployment in situations such as search and rescue, disaster relief or medical emergencies. Wearable sensors are often applied in self-contained PDR, but implementation varies in terms of the number, type and location of sensors used. Many algorithms are designed for PDR in order to reduce the error or drift of the final estimate, with various levels of success. There is a lack of comparison between these different methods and this systematic review of PDR for wearable devices provides a comprehensive overview that can inform further design optimizations. The aim of this article is to assess the quality of all available PDR literature with a focus on wearable sensors. It provides an outline of the state-of-the-art in the field by comparing the accuracy of different sensor layouts and algorithms. Further directions of research are suggested based on these results. This study also highlights the need for more standardised and robust assessment protocols to capture real-world tracking performance of PDR methods.
Reconsidering the Effects of Work on College Student Leadership Development: An Empirical Perspective

Abstract:Most college students work for pay while enrolled, however theoretical and methodological concerns with the extant literature make it nearly impossible to understand how employment affects students. Responding to those shortcomings, I designed a validation study with robust statistical methods to examine relationships between student employment and leadership in a sample of nearly 36,000 students across 87 colleges and universities, recognizing that paid work provides an equitable, skills-focused environment in which students may refine and practice their own leadership skills. Findings suggest that working while enrolled is associated with lower self-reported capacity for socially responsible leadership and that this association varies across on-campus workplace locations and institutional characteristics. Recommendations are offered for supervisors to effectively incorporate socially responsible leadership into student employment structures and tasks.
Relationship between Job Satisfaction and Depression, Anxiety and Stress among the Female Nurses of Dhaka Medical College and Hospital, Bangladesh

High workload, psychosocial stressors, physical labour, emotional labour, shift work and so on puts nurses at risk for short-term and long-term health problems, including sleep disorders, depression, psychiatric disorders, stress-related illnesses and illness in general. The context of Bangladesh is also not that different, since it has the lowest number of nurses in the sub-continent which results a staggering shortage. The main objective of this study was to find out the relationship between job satisfaction and depression, anxiety & stress among the female nurses in Dhaka Medical College and Hospital, Bangladesh. This cross sectional study was conducted among purposively selected 310 female nurses for the period of six months. A face to face interview through a semi structured questionnaire was applied to collect the data. The information about depression, anxiety and stress, and job satisfaction level, and socio-demographic factors and the presence of chronic illness was obtained through DASS 21, Minnesota satisfaction (Short form) and pre-tested questionnaire. A computer program “R” version was used for data analysis. The unadjusted association between each of categorical variable and stress, anxiety and depression were evaluated by chi square test. The associated factors of stress, anxiety and depression were estimated by multivariable logistic regression model. Moderate to severe level of stress, anxiety, and depression was experienced by 20%, 65%, and 40% of the nurses respectively at work. On the other hand, 80% of the nurses experienced normal stress at work whereas 35% and 60% of the nurses did not experience any anxiety and depression. In regards to job satisfaction level, 18%, and 35% of the nurses were satisfied, and dissatisfied with their job respectively. Job satisfaction level has a significant relationship with anxiety & depression but not with the stress. Low back pain and owning a house has been identified as significant variables for developing stress. The job satisfaction level and age group both have been observed as significant variables for depression and anxiety along with other factors. Due to shortage of man power, nurses are at high risk of developing mental disorder in Bangladesh. Therefore, proper interventions need to be placed for preventing this phenomenon to happen.

Dual-Band Transmitarray With Low Scan Loss for Satcom Applications

This communication presents the experimental validation of independent and wide beam scanning with a dual-band transmitarray antenna (TA) in Satcom up- and down-links at <italic>Ka</italic>-band. The TA consists of two subarrays: one operates in the down-link with central frequency at 19.5 GHz, while the other one operates in the up-link centered at 29 GHz. Both subarrays share a common radiating aperture to obtain the compact configuration. The TA layout is made of 1 bit unit-cells and its design relies on the bifocal technique to extend the beam-scanning capability. The proposed bifocal prototype includes 1500 up-link unit-cells in a <inline-formula> <tex-math notation="LaTeX">$30\times50$ </tex-math></inline-formula> matrix and 1581 down-link unit-cells arranged in a <inline-formula> <tex-math notation="LaTeX">$31\times51$ </tex-math></inline-formula> rectangular lattice. The 1-D scanning is validated by displacing the feed horn along one direction. We show that the TA beam can be scanned in a ±40° and ±30° independently in each band while keeping a very low scan loss (<2 dB).
Static Eccentricity Fault Diagnosis in Wound-Rotor Resolvers

In this paper static eccentricity (SE) fault diagnosis in wound rotor (WR) resolver is considered and a new noninvasive index is proposed. Using the proposed index not only leads to SE detection but also, helps to precisely determine the eccentricity level. Furthermore, the location of the fault is determined using two search coils. In this regard, a mathematical model based on the winding function method is proposed. In the proposed model the influence of non-uniform air-gap length on calculating the inductances is considered. Then, time-stepping finite element method (TSFEM) is used for approving the success of the proposed index. Finally, experimental tests are done to validate the simulation results.
Post-Mortem Examination of a Female Elephant Suspected of Having Degenerative Joint Disease: A Case Report

| The musculoskeletal impairments are one of the major health challenging issues of captive elephants in zoos. This is a case study of 45 years old female African Elephant (Loxodonta africana) named Laila, kept at Riyadh Zoological Garden, Al Malaz Ar Riyadh, Saudi Arabia. There were total 3 female African elephants in the zoo and Laila was the eldest one. The elephant Laila was fed on fresh berseem and leaves, lucern hay, rhodes grass, pellets, molasses, rice, seasonal vegetables and fruits (Banana, Apple, and Orange). Facility of adequate water was provided by keeping drums of 100 litres capacity. The elephant was captivated at night quarters having cemented floor while during day time it was allowed to walk on soil. Usually one hind limb of the elephant was tethered with chain. The animal was found falling down repeatedly and unable to bear weight on limbs while attempting to stand up. Walking Activity was gradually decreased and ultimately total reluctance to walk. Bones were malformed grossly and splaying was evident. The elephant was suspected for gradual aging and related Degenerative Joint Disease. The animal was on continuous supportive medicines from the last few months. The animal was also under hot water hydrotherapy for quicker recovery from Degenerative Joint Disease. At the end, the elephant died when constant pain and lameness became unresponsive to protracted treatment. Post-mortem examination of elephant was conducted at post-mortem block of the zoo. When bones, joints and joint cavities were observed, articular surfaces of bones were found fragile and inflamed. Synovial fluid was less viscous. Bone density was extremely low and cracked sole was also found on palmer surface of right limb. It was suspected in the necropsy that the elephant was suffering from Degenerative Joint Disease.
Epidemic Heterogeneity and Hierarchy: A Study of Wireless Hybrid Worm Propagation

With the growth in the use of smart mobile devices and the development of information technologies, worms and malware can spread from mobile networks into heterogeneous and hierarchical networks. Thus, the spread of these worms constitutes an increasing potential threat. For understanding the propagation of the aforementioned wireless hybrid worms, current researches have three critical problems: Structural simplification of network topologies (previous research object for wireless worms is the mobile network), Homogenous population of network devices (properties of network devices are the same), and Inaccuracy of propagation models (traditional deterministic differential or stochastic difference models cannot model propagation of wireless hybrid worms accurately). To address them, we propose a novel compartmental population-based propagation model oriented towards heterogeneous and hierarchical networks with human behaviors, and then study the impacts of user mobility and operation behaviors on worm propagation. Meanwhile, we conduct extensive simulations to show our model can characterize propagation features accurately. The results in this paper not only provide a deep understanding of new worm propagation, but also serve as fundamental defense guidelines.
Commentary of Expertise on the Epigenetic Program during Intrauterine Development

Preterm infants reflect the influences of their early intrauterine environment at birth and are placed in a nonphysiological environment after birth. We have studied the epigenetics of the Glucocorticoid Receptor (GR) and the Insulin-like Growth Factor 1 (IGF1) gene, which are important in later life. Our studies indicate that these genes are mainly modified epigenetically after birth. The postnatal environment overlaps the prenatal condition, causing modification of these genes. Our studies may imply an adult disease onset model and a critical view on transgenerational inheritance in humans through epigenetic changes in gametes.
Classification of Epileptic Resting-State Electroencephalogram Signals Based on Machine Learning and Cross-Spectrum Features

—We used machine learning tools to discriminate resting-state brain electrical activity measured with electroencephalography (EEG) of patients with refractory epilepsy (RE) from healthy controls (HC). We propose a cross-spectral density-based measure as a signal feature to distinguish between healthy and epileptic subjects using machine-learning algorithms linear discriminant analysis (LDA) and support vector machines (SVM). The resting-state EEG of epileptic patients were obtained from interictal periods without any epileptiform activity. We recorded from 11 epilepsy patients and 7 healthy age-matched controls. Both algorithms obtained 100 % accuracy. Our results show that a distinction between the two groups is possible with high accuracy when a 190-dimensional feature vector is used as input.
Study of physicochemical parameters affecting the release of diclofenac sodium from lipophilic matrix tablets

In the present work different parameters, which influence the release of diclofenac sodium (2-[(2,6-dichlorophenyl)amino]benzeneacetic acid mono sodium salt) from lipophilic matrix prolonged release tablets, were investigated. Solubility characteristics of diclofenac sodium in aqueous media with various ionic strengths, ionic compositions and pH in the range of 1 to 10 were determined. According to the obtained results different experimental conditions of the dissolution test on the drug release profiles were studied, i.e. different dissolution apparatus, various rotation speeds of the stirring elements, different buffer media with a pH in the range of 5.8 to 10.0 and various ionic strengths. The amount of released diclofenac sodium was determined by ultraviolet spectrophotometry at the wavelength of maximum absorbance at 276 ′ 2 nm. From the obtained results it can be concluded, that solubility of diclofenac sodium depends mainly on composition and pH of the dissolution medium and also on ionic strengths of the dissolution medium. Besides these parameters, on the release of diclofenac sodium from lipophilic matrix tablets influence also type of dissolution apparatus and particularly rotation speeds of the stirring elements.

This chapter analyses experiences of violence among queer immigrants in Norway. The aim of the chapter is to explore the various experiences of violence, and how vulnerability to violence is related to the wider patterns of discrimination and juridical, economic and social marginalisation. Based on an inductive analysis of interviews with 41 lesbian, gay, bisexual, trans and intersex people with immigrant backgrounds, we have identified four key themes: 1) Sexual abuse, 2) violence in relation to coming out as queer, 3) exposure to violence within Norwegian institutions dealing with immigration and integration, and 4) racism and violence. The experiences of violence that the participants talk about include violence from family members, acquaintances, strangers and representatives of public institutions. In order to understand queer immigrants’ experiences of violence, it is necessary to focus on the interconnectedness of various forms of violence that take place in different arenas and in different relationships. Moreover, violence needs to be understood in connection to discrimination and marginalisation based on the status as immigrant and queer.
