Can a tensorial analogue of gravitational force explain away the galactic rotation curves without dark matter?

The dark matter problem is one of the most pressing problems in modern physics. As there is no well-established claim from a direct detection experiment supporting the existence of the illusive dark matter that has been postulated to explain the flat rotation curves of galaxies, and since the whole issue of an alternative theory of gravity remains controversial, it may be worth to reconsider the familiar ground of general relativity (GR) itself for a possible way out. It has recently been discovered that a skew-symmetric rank-three tensor field — the Lanczos tensor field — that generates the Weyl tensor differentially, provides a proper relativistic analogue of the Newtonian gravitational force. By taking account of its conformal invariance, the Lanczos tensor leads to a modified acceleration law which can explain, within the framework of GR itself, the flat rotation curves of galaxies without the need for any dark matter whatsoever.

User Grouping and Energy Harvesting in UAV-NOMA System With AF/DF Relaying

The development of unmanned aerial vehicles (UAVs) is one of the driving forces for revolutionizing wireless communications in the modern era. Although there are many unique features of UAV networks, their widespread use is still hampered by the short battery life. As a result, most of the research efforts in this domain mainly have focused on the efficient use of energy through trajectory planning and cooperative communication. While there have been a few proposals to use energy harvesting techniques for UAV networks, a complete understanding of the performance limits of such networks is still missing in the literature and needs further investigations. Within this context, our paper provides a comprehensive performance evaluation of UAV relay networks (UAVRNs) employing non-orthogonal multiple access (NOMA) technique. Specifically, a cooperative communication system, where a UAV serves as a mobile relay, is fully considered. The UAV relay is considered to be wirelessly-powered and harvests energy from the radio signals received from a nearby base station. For the sake of comparison, both amplify-and-forward (AF) and decode-and-forward (DF) relaying protocols are considered. Subsequently, the closed-form expressions of outage probabilities and ergodic capacities are provided for each UAV relaying protocol. Extensive simulations are performed to verify the accuracy of the derived closed-form expressions. The results provided in this work characterize the outage and ergodic capacity performance of NOMA-enabled UAVRNs.
The effect of work motivation, work environment, and job satisfaction on organizational citizenship behavior and their impact on employees performance of RSU Menteng Mitra Afia during the Covid-19 pandemic

The current Covid-19 pandemic has resulted in many hospitals in the world experiencing difficulties both in terms of management and infrastructure in providing services because the number of patients has increased in a short time. The human aspect has a significant role in hospitals, with the characteristics of various ages, education levels, position levels, and length of work. Menteng Mitra Afia General Hospital (MMA GH) is one of 144 hospitals in Jakarta that accepts COVID-19 patients and has had significant changes in terms of service and management. In this study, the authors succeeded in analyzing the influence of work motivation, work environment, and job satisfaction on Organizational Citizenship Behavior (OCB) and their impact on employee performance at MMA GH during the COVID 19 pandemic. Sampling method with a total sampling of 121 respondents from the population of employees who returned the questionnaire. The technical data analysis technique uses the Structural Equation Modeling, where the data processing uses the Partial Least Square (Smart-PLS) version 3.0 program.

The conclusions that can be drawn from the results of data analysis and discussion are as follows: (1) Work Motivation has an effect on OCB (2) Work Environment has no effect on OCB (3) Job Satisfaction has an effect on OCB (4) Work motivation has an effect on Employee Performance (5) OCB has an effect on Employee Performance (6) Job Satisfaction has an effect on Employee Performance at MMA GH.
Effects of Human–Machine Interface Design for Intelligent Speed Adaptation on Driving Behavior and Acceptance

The effects of human–machine interface (HMI) design for intelligent speed adaptation (ISA) on driving behavior and acceptance were measured in a moving-base research driving simulator. Sixty-four experienced drivers participated in two simulator experiments (32 in each). During the simulated runs with ISA, the speed limit was communicated through the ISA system. The ISA system consisted of an indication of the speed limit on the speedometer and a gas pedal that could be used either as a haptic or tactile pedal or as a dead throttle. Two versions of the haptic gas pedal were examined in Experiment I: a low-force ISA (easy to overrule, informative in nature) and a high-force ISA (stronger counterforce, more compulsory in nature). Two other configurations were tested in Experiment II: a tactile pedal (a vibration on the gas pedal, informative in nature) and a dead throttle (completely restraining the driver from exceeding the speed limit). It was hypothesized that the closer the ISA is to an informative type, the higher the acceptance and the smaller the effects on driving behavior would be. This hypothesis appeared to be valid, although for both driving behavior and acceptance, not all four HMIs could be ranked unambiguously on the scale from no ISA to full ISA. In sharp curves, drivers appeared to choose a driving speed below the speed limit, irrespective of ISA. The specific road environment scenarios that were inserted to examine presupposed compensatory behavior for experienced delay indicated no signs of compensatory driving behavior.
Hydrologic responses to climate and land-use/land-cover changes in the Bilate catchment, Southern Ethiopia

The likely effects of climate and land-use/land-cover (LULC) changes on hydrologic processes in Bilate catchment, Ethiopia were evaluated. The study emphasizes the evaluation of individual and combined impacts on hydrologic responses of climate and LULC changes. Climatic scenarios included a downscaled regional climate model from CORDEX-Africa. The CA–Markov model was used to project LULC. The results revealed that distinct changes on hydrologic responses occurred which follow the direction of climate and LULC changes. A 30.87% decline in rainfall resulted in about 4.09, 1.43 and 3.57% decline in runoff, groundwater and water yield, respectively. A rise in mean temperature by 1.3 °C resulted in a 7 and 0.8% increase in potential and actual evapotranspiration, respectively. Runoff, groundwater and water yield are projected to decrease by 11.24, 12.54 and 11.54%; however, potential and actual evapotranspiration are projected to increase by 19 and 14.7%, respectively, under combined climate and LULC changes. The joint effects of climate and LULC changes on hydrologic responses in the forthcoming were higher than the variation trend of climate or LULC change alone. Climate change compared with LULC change has a higher impact on hydrologic responses. The results obtained provide further insight into future water balance, and assistance in water resources planning and management.
Effect of Nanofluids on the Enhancement of Boiling Heat Transfer: A Review

Boiling heat transfer can play a vital role in the two-phase flow applications. The analysis of the boiling hat transfer enhancement is of importance in such applications and the enhancement can be mostly conducted by using various active and passive techniques. One type of passive techniques is the enhancement of heat transfer by nanofluids. This article presents an extensive review on the effect of different nanofluids on the enhancement of heat transfer coefficient (HTC) and critical heat flux (CHF) for both pool as well as flow boiling. Nanoparticles addition to a working fluid is done arbitrarily to improve the thermophysical properties which in turn improves heat transfer rate. Numerous works have been done in the studies on nanofluid boiling. Among various nanoparticles, the most frequently used nanoparticles are Al2O3 and TiO2. In the case of binary nanoparticles, the most commonly used combination is Al2O3 and TiO2. After reviewing the relevant literatures, it is found that for pool boiling, the maximum HTC is increased to 138% for TiO2 nanoparticles and the maximum CHF is increased to 274.2% for MWCNTs. Conversely, in flow boiling the maximum HTC is increased to 126% for ZnO nanoparticles and the maximum CHF increased to as 100% for GO nanoparticles. In addition, when two or more nanoparticles in succession or binary nanofluids are used the CHF in pool boiling increased up to 100% for Al2O3 and TiO2 as well as the CHF in flow boiling increased up to 100% for Al2O3, ZnO, and Diamond. Though the information of the coefficient of heat transfer and the critical heat flux varied for different nanofluids and vary from experiment to experiment for each of the nanofluids. This variation happens because the coefficient of heat transfer and the critical heat flux in boiling is dependent upon several factors.
Analysis of the overturning moment caused by transient liquid slosh inside a partly filled moving tank

Abstract A non-linear fluid slosh analysis of a partially filled circular tank is performed to illustrate the significance of transient fluid motion on the resulting destabilizing forces and moments imposed on the tank structure and thus the vehicle. The analyses are performed on a clean bore tank of circular cross-section for various fill volumes and subject to different magnitudes of steady as well as harmonic lateral acceleration using the FLUENT software. The results of the study are presented in terms of transient forces and moments caused by the cargo slosh, which directly relate to the roll dynamic performance of the partly filled tank trucks. A relationship between the lateral force and the resulting roll moment is derived, which suggests that the roll moment could be defined as a function of the horizontal force and tank radius, irrespective of the translation of the centre-of-mass coordinates. The deviations of the forces and overturning moment from those predicted using quasi-static (QS) load shift analysis are also presented and discussed. The influence of fluid viscosity on the transient behaviour is further investigated under time-varying lateral acceleration in terms of slosh damping rate and peak responses. The results of the study suggest that the magnitude of transient roll moment could be 1.57 times larger than corresponding mean values that are very close to those predicted using the QS analysis. Analysis of the partly filled tank under harmonic lateral acceleration excitations shows that the peak values of the lateral slosh force and the overturning moment occur during the first oscillation. The magnitude of the peak overturning moment is strongly dependent upon the frequency of the lateral acceleration excitation.

Verbal overshadowing at an immediate Task-Test delay is independent of Video-Task delay

ABSTRACT We sought to identify the sources of effect size differences in replications of the verbal overshadowing effect: the negative effect of verbally describing a face on later recognition of the face (Schooler & Engstler-Schooler, 1990). Comparisons of the original findings with those in a registered replication report (Alogna et al., 2014) showed differences in the patterns of recognition in the criterial conditions defining the verbal overshadowing effect. The review indicates that although verbal overshadowing is strongest when the recognition task immediately follows the verbal description task, that delay variable is confounded with the delay between the encoding of the face and the verbal description task. We varied the delay between face encoding and the verbal description task under conditions where the recognition test immediately followed the description task. The verbal overshadowing effect was independent of the delay between face encoding and verbal description of the face.
A durable, shock-resistant electromagnetic optical scanner with polyimide-based hinges

This paper presents a moving-coil electromagnetic optical scanner with newly developed hinge structure consisting of multilayered polyimide films with aluminum lead wires in between. The main purpose is to obtain a scanner with good durability and shock resistance for practical use. Polyimide has both features, and the aluminum lead wires, connecting the moving-coils and fixed electrode pads, are more reliable, because they are located inside the hinge, where the stress caused by torsional deformation and atmospheric degradation are minimal. An electromagnetic actuator is used to satisfy the following requirements; a millimeter-sized mirror, resonant and galvanometric operation, and scan angle control. Scanner prototypes with two different specifications (i.e., fast scanner and slow scanner) were fabricated and characterized. Driven with a sinusoidal current of /spl plusmn/20 mA, the fast scanner and the slow one vibrated with an optical scan angle (/spl theta//sub o/) of 1/spl deg/ at the resonant frequency (f/sub r/) of 1.7 kHz and /spl theta//sub o/ of 60/spl deg/ at f/sub r/ of 72 Hz, respectively. Durability was demonstrated with a shock test of 2500 G and a life test of over 13 000 h. By substituting sputtered aluminum driving coil with electroplated copper coil, improved /spl theta//sub o/ of 16.8/spl deg/ was obtained at f/sub r/ of 2.7 kHz.
Two-port resonator of axially magnetised gyroelectric disk

Many novel rf and microwave nonreciprocal devices exploit the gyromagnetic property of ferrites. Similar principles should also be applicable to those materials with gyroelectric property such as semiconductors according to the Drude model. The work reported here concerns a very simple structure, that is a two-port axially magnetised semiconductor disk. Assuming no axial variation in the electromagnetic field and adopting the Green's function analysis approach, the S-parameters of the resonator are derived. The theoretical frequency response of an Indium Antimonide disk cooled to 77 K is presented. The sharpness and location of the peaks in the insertion response of the resonator are observed to be material dependent. This method provides a way to calibrate the semiconductor materials and to verify the model. It may prove to be the vital help in the realisation of a three-port semiconductor junction circulator for high-T/sub c/ superconductivity circuits.
Bioelectrical Phase Angle as a Factor Associated with Mobility Limitation in Older Cardiac Inpatients

The number of elderly individuals with cardiac disease is increasing in countries with aging populations, such as Japan. For example, in large-scale cohort studies of Japanese adults with chronic heart failure, 60%70% of subjects were aged 65 years or older. Older cardiac patients often have additional health issues, such as poor physical function, cognitive impairment, and comorbidity. This can lead to a complex clinical condition and make treatment more difficult.

Technical feasibility and effectiveness of vermicomposting at household level

Understanding the value of vermicompost, an attempt was made to study the technical feasibility and effectiveness of vermicomposting at household level and to analyze and compare the performance of the crops grown using vermicompost. The study was carried out during April (2013) to January (2014) at Madampe in Puttlam, Sri Lanka. Initially three vermicomposting units were established separately using six plastic bins with 45 cm diameter and 40 cm height each. The locally available earthworm species, Eisenia fetida and Eisenia andrei were used to prepare vermicompost using shredded paper as the bedding material. Five treatments with five replicates of control (T1), inorganic fertilizer (T2), vermicompost (T3), garden compost (T4), and a combination of vermicompost + inorganic fertilizer (50:50) (T5) were tested with potted okra (Abelmoschus esculentus) using randomized block design. The growth parameters and the yield characteristics were recorded during the period of six to fifteen weeks of planting. The data were statistically analyzed using ANOVA and LSD test. Results revealed that the average marketable fruit yield per plant for T3 was the highest among five treatments. The results indicated that there was a significant difference between vermicompost and other treatments on the average marketable yield of okra. The average yield of T3 showed 63%, 50% and 37% increase compared to that of T1, T2 and T4 respectively. It also showed 18% increase of yield in T5 when compared to T2. Vermicomposting provide an environmental friendly way of increasing the crop yield. Use of local earthworms to the typical process of vermicomposting could be a successful and a
Palliative Psychiatry for Patients With Severe and Persistent Mental Illness: A Survey on the Attitudes of Psychiatrists in India Compared to Psychiatrists in Switzerland

Objectives Palliative psychiatry is a new approach for the care of patients with severe and persistent mental illness (SPMI) which systematically considers biological, psychological, social, and existential factors of care. To assess the attitudes of psychiatrists in India toward palliative psychiatry for patients with SPMI and to compare these to the attitudes of psychiatrists in Switzerland. Methods In an online survey, data from 206 psychiatrists in India were collected and compared with data from a previous survey among 457 psychiatrists in Switzerland. Results Psychiatrists in India generally considered it very important to prevent suicide in SPMI patients (97.6%). At the same time, they considered it very important to reduce suffering (98.1%) and to ensure functionality in everyday life (95.6%). They agreed that palliative psychiatry is important for providing optimal care to SPMI patients without life-limiting illness (79.6%) and considered palliative psychiatry as indicated for patients with SPMI (78.2%). By contrast, curing the illness was considered very important by only 39.8 % of respondents. Relative to psychiatrists in Switzerland, psychiatrists in India were significantly more concerned about preventing suicide and less willing to accept a reduction in life expectancy, even at the expense of quality of life in patients with severe and persistent schizophrenia and recurrent major depressive disorder. At the same time, they were significantly more likely to advocate palliative psychiatry. Conclusion Most of the participating psychiatrists in India agreed that palliative psychiatry can be indicated for patients with SPMI. The comparison with psychiatrists in Switzerland highlights the need to take account of cultural differences in future studies of this kind. In summary, this study shows the potential of palliative psychiatry as a genuine biopsychosocio-existential approach which systematically integrates biological, psychological, social, and existential factors of care.
