Authors: Dhanabhakyam Dr. M. , Joseph Emil
Published: April 2022

A satisfied employee is an asset for any organization to produce good results. Further, some of the research studies have shown that the productivity of organizations improves if the satisfaction level is high. Employee Satisfaction happens through a host variety of factors, one of the proven factors for employee satisfaction is "Salary". There were many motivation theories and research conducted on employee satisfaction. Almost all research is always novel due to their contribution and identification of a new phenomenon to Satisfaction. The present research work is also intended to study employee satisfaction taking the variables from previous studies. The current work is majorly focused on academic fraternity, whose contribution is highly essential in producing the next generation in any educational set-up. Unfortunately, not much research happened in this direction. Primary and Secondary data were used for data collection. A simple percentage method was used and considered 120 faculty members, specifically from the arts and science colleges, collected through a well-structured questionnaire. Methods used are Simple percentage analysis, Weighted mean, Cronbach's alpha (Reliability), Chi-square test, Standard deviation, and Ranking. Therefore, the present research work is intended to fill that gap. The study aims to find the Factors influencing the Satisfaction of faculty members working in fine Arts and Science colleges in Palakkad District, Kerala. The research paper initially focused on employee satisfaction on various parameters and then studied the phenomenon during the Covid-19 Pandemic. The pandemic has devastating effects on academic fraternity satisfaction levels, especially in India. A host variety of reasons captured in this study, and finally, the paper ends with some of the suggestions to make a healthy work environment for a happy and satisfied work-life to provide to the community good academic pursuits.

Published: April 2022

Alzheimer’s disease (AD) is progressive, irreversible, neurodegenerative memory disorder linked with somehow aging and comes under the umbrella of dementia. It may be rare Familial AD or randomly occurring Sporadic AD. Some preventable acquired risk factors and non-preventable e.g., age and genetics are the main risk factors for Alzheimer’s. The most essential genetic risks factor for (LOAD) late onset of Alzheimer’s disease is APOE genes present on chromosome 19, has three major alleles (e2, e3, and e4). We can slow Alzheimer’s but cannot prevent or stop it till now. Some non-drug treatments, like physical activity, social engagement, nutritious supplemented food, and FDA approved drugs i.e., Donepezil, Galantamine, cholinesterase inhibitors, Mementine, Antidepressants, Antipsychotics and mood stabilizing medication helps to reduce AD.
Hegel ante el capitalismo industrial: la pobreza y la plebe como residuos del Estado moderno
Authors: Pérez Andrés
Published: April 2022

El presente escrito tiene como objetivo aproximarse a lo que ha sido la gran “fisura” de los “Principios de la filosofía del derecho”: el aumento ingente de pobreza en el seno de las sociedades industriales modernas. A partir de su filosofía gris, carente de soluciones, Hegel aporta una filosofía política cuya estructura lógica y coherencia no escapa del latido de la negatividad que ostenta todo acontecer histórico, dando cuenta de las contradicciones de los mismos elementos que vertebran aquella realidad tal y como es. En este sentido, la pobreza no será vista ya como mero daño colateral de la abundancia o como una intrusión externa dentro de la sociedad civil y enfrentada al Estado, sino como el fundamento del mismo orden existente. La lectura de Hegel conducirá a aproximarse a las propias “fisuras” de la realidad y, muy especialmente, a los límites de la racionalidad moderna, cuyo nivel de abstracción y desapego de la realidad parece generar un incontenible amontonamiento de residuos imposibles de recoger por la misma.
Assessment of Marine Coastal Water Pollution from Karachi Harbour Pakistan
Authors: Nergis Yasmin , Butt Jawad Abdullah , Sharif Mughal
Published: April 2022

: In Pakistan, marine pollution is a major problem that is caused by the waste from industrial, municipal,agronomy, and oil leak sources. The pollutant loads along with the coastline areas near Karachi is received fromterrestrial contaminants including discharges from Karachi Harbour located on the estuary of the Lyari river. Karachigenerates 472 Million Gallon per Day (MGD) of wastewater out of which only 55 MGD is treated and the rest isdischarged in the sea. The prevailing sewage treatment plants are functioning at reduced capacity due to the insufficienttransmission capacity of interceptors. Water sampling was carried out from the Lyari River and five different selectedcoastal point around Karachi harbour for physicochemical parameters and selected heavy metals. Results show that theKarachi Harbour area is noticeably polluted, whereas; the coastal environment in the vicinity of Karachi is also underthe stress of pollution. High COD and BOD5 values were noticed at the Lyari river samples and the sampling locationsclose to the Lyari river outfall area. The Pb, Cd, Ni, and Hg heavy metals that pollute marine water are found. Thissituation is due to the discharge of mixed effluents of industrial and domestic wastes as well as dredging, cargohandling, dumping of ship waste and other coastal activities. The highest value of pollution observed at KarachiHarbour which is near Lyari river mouth, where the domestic and industrial effluents with organic and inorganic wasteshave a greater influence on the water quality and the marine environment. At present, there is no effective controllingmechanism for industries to treat their waste, nor has any investigation to assess increasing marine pollution beencarried out. As a result, there is an adverse impact on fish habitat and mangroves, corrosion of cargo ships, navalvessels and the residents living in the coastal area. Therefore, the government agencies and industrial sectors shouldwork together to avert marine pollution and attain total environmental sustainability.

Published: April 2022

The problem of exposure to traffic noise pollution is rapidly increasing day by day and is closely associated with the rapid industrialization and urbanization process taking place over the glob (Margaritis and Kang, 2016). Nowadays, more than 54% of the world’s population lives in urban areas, a proportion that is expected to increase to 66% by the year 2050 (United Nations, 2018). The special effects of vegetation cover on propagation of sound have been the theme of much debate for a number of years (Bell et al., 2007). There is increasing evidence that this is not always true and a significant reduction of noise may be accomplished through vegetation cover if present in adequate density and depth (Peng et al., 2014). Development in urban transportation is increasing day by day. Transportation of goods from one place to another place has become very easy. Specifically, in urban areas, it is common to move people and goods from one place to another. The use of transportation in terms of vehicles makes noise. The noise of vehicles causes many problems including health issues (Monazzam et al., 2015). Noise pollution is very dangerous for human health (Selander et al., 2009). It is also very harmful to the environment. It adversely affects the quality of the environment. Noise pollution badly affects mental health. It develops aggressiveness in public. It leads to higher blood pressure. It increases the stress level. 65 dB of routine contact can cause hypertension. A level of noise above 75 dB can cause stress. It also causes heart diseases. It can cause hearing loss. The cases of noise pollution complaints are more than other environmental issues (Doygun and Gurun, 2008).

Published: April 2022

"This paper presents the work of an R&D project which aims to augment IDIADA’s capabilities in the prediction of aerodynamically generated passby noise via CFD simulations. The project focuses on the noise generated by the A-pillar and the side view mirror of IDIADA’s iShare concept car and combines numerical and experimental investigations. The objective is to develop and validate the numerical aeroacoustics methodology, as well as to develop an experimental methodology that makes use of IDIADA’s semi-anechoic chamber. The main numerical methodology used was based on the surface integral formulation of Ffowcs Williams-Hawkings, this is an acoustic analogy which splits up the problem to the local noise generation first and to the propagation of the acoustic wave second. For the local noise generation two approaches were used, a compressible and an incompressible one. The latter assumes that the acoustic field has a negligible effect on the hydrodynamic flow field, which simplifies the physics involved. The technique uses the theory of Acoustic Perturbation Equations to model the acoustic field that is generated by the flow of an incompressible fluid. The solver used was STAR-CCM+. Parallel to the numerical methodology development the project developed an experimental methodology. This involved the design of a nozzle that could channel the available flow of the semi-anechoic chamber into a high velocity jet that could be directed towards the A-pillar or the side view mirror of a vehicle, thus focusing the noise generation in these features. Finally, the numerical tests were compared to the experiments for validation. The paper will present the numerical and experimental SPL measurements in an array of microphones placed 0.6m away from the left hand side of the iShare, as well as, CFD visualisations of the flow field generated and of the noise sources. The numerical results follow the trends of the experimental results, but for certain frequency octaves there was a small deviation in the predicted SPL. Overall the agreement was satisfactory. This work has shown the potential of the methodologies used to solve aeroacoustics problems and the limitations of what can be tested in IDIADA’s semi-anechoic chamber and of the numerical methods. The paper will elaborate in detail on these findings. This is a new field for IDIADA, and it offers a new aeroacoustic validation case for numerical codes to be compared against."
Acoustic target qualification on test bench with 3D array technology: application to turbocharger sound power emission
Authors:   MicrodB, FRANCE, PINEL LAMOTTE Lucille , Millot Alban ,   CRITTM2A, FRANCE
Published: April 2022

"The acoustic specification of a new project, vehicle or engine, is facing the difficulty of cascading NVH targets to the component level quantitatively. However, these specifications are the basis of discussion between constructors and suppliers and each of them would appreciate to discuss on more reliable data input. It is so necessary to construct reliable database/references. It requires measurement tools able to determine on a previous project the contribution of each of the component to the complete noise emission. The sound power is one of the criteria used in the acoustic specification, but it can be completed with criteria aimed at controlling the acoustic signature, especially with the new electric technologies. The standard measurements usually based on sound intensity scanning or sound pressure emission to achieve sound power measurement do not permit to extract any sub-value without masking methodology which can be long for panel qualification or even unfeasible on engine. A new technology based on 3D acoustic array measurement permits to extract the individual sound power of each of the component or any other criteria from the spectral signature. It is parented to an experimental modelling. The complete sound field is recorded with several array positions and is then back-propagated on the 3D mesh of the source distribution taking account the object diffraction. It is carried out by a complex inversion of the system. The acoustic imaging usually used for fast acoustic diagnosis becomes a powerful tool to help in the definition of acoustic specification. This 3D technology can be used on engine bench to define the future target from the preceding experience, or coupled rooms to measure Transmission Loss or gas stand for Turbo Compressor… and any test bench useful for supplier to validate the acoustic target. This paper will briefly present the 3D array technology and its application on turbocharger component to quantify the duct transmission loss. The methodology will be applied on the same turbocharger line mounted on engine compartment and then on gas stand. The innovative 3D acoustic array measurement permits to quantify the sound power emitted outside the duct and a 3 microphones techniques permits to quantify the sound power inside the duct. By subtraction of interior and exterior sound power, the obtained transmission loss results in both experimental conditions will be compared. It will point out a nice example of component qualification on test bench with a good reproduction of true engine conditions."

Milk production in dairy cows has increased significantly in the last few decades and continues to increase. The beginning of lactation requires extremely great effort from cows to overcome metabolic stress, so the frequency of cows' illness is the most intense in this period. Significant variations in the adaptive responses to lack of energy and nutrients in this period occur in the body of cows, with numerous endocrine, hematological, immunological and other changes. Therefore, cows should be provided with adequate nutrients for a balanced meal, both in the period of drought and in all phases of lactation.

Pigs belong to a rare group of domestic animals that are bred only for one type of product - meat. There is a difference between open and closed rearing systems in organic pig farming. An open rearing system means keeping sows outdoors during whole year, which means in summer when pigs are exposed to high temperatures and in winter when they are exposed to rain, snow and wind. Therefore, it is recommended to make a shelter in the area where the sows are staying, where they will take shelter from unfavorable weather conditions. The closed rearing system largely limits natural movements and movements, and especially activities due to the urge to digging. The most common systems of facilities for housing sows are two-part, three-part and the so-called stolba pen.

Published: April 2022

This research examined from a legal perspective regarding the unilateral termination of employment by PT Indosat Tbk, during the Covid-19 Pandemic. Two main issues were discussed in this study, the first was the chronology of unilateral termination carried out by PT Indosat Tbk to its employees during the Covid-19 pandemic, and analyzing the legal termination procedural during the Covid-19 Pandemic. This study used a normative juridical research method using secondary legal data. Based on the results of the study, it was known that the chronology of layoffs was carried out by PT. Indosat, Tbk to its workers during the Covid-19 pandemic was unilateral. Meanwhile, the legal termination procedure during the Covid-19 pandemic must go through the stages of negotiations between the employers, in this case, PT. Indosat, Tbk with employees represented by existing labor associations. In its implementation carried out, PT. Indosat, Tbk did not carry out negotiations before carrying out simultaneous termination. In connection with the above, the employer should negotiate first before implementing efficiency by doing the termination of employment (PHK).

Published: April 2022

The use of Ground Source Heat Pump (GSHP) systems is promising in reducing the energy consumption in the households and services sector, which accounts for almost 40% of the total energy consumption in Europe and in Northern America. There is an increasing interest in combining such earth energy systems with solar energy. In this study, three Solar Assisted Ground Source Heat Pump configurations comprised of Flat-Plate (FPC), Photovoltaic (PV) and hybrid Photovoltaic/Thermal (PV/T) collectors are investigated aiming at upgrading an existing GSHP system installed in a university building complex at in Volos, Greece. These systems were simulated with the dynamic system simulation tool TRNSYS and were assessed on energy performance and on an economic and an environmental basis. Results of the analysis showed that the PV system is the best option due to its substantial energy savings and to the lower cost compared to the PV/T system.

Australian higher education participation continues to expand, yet in unequal ways. Regional, rural, and remote (RRR) student participation is stubbornly stalled, despite sustained research and policy initiatives to support these cohorts. To address this complex issue, we interviewed 10 RRR principals in Queensland and Victoria to explore specific challenges that face RRR communities, as well as collate strategies and solutions. Our findings highlighted the importance of leveraging and developing local knowledge and expertise to equip students with careers education, as well as the need to promote a positive narrative about RRR community life. A key theme that emerged from participants was the need to dispel the myth that students needed to leave their communities to achieve their goals or find career success. The findings from this paper point to a need for educational outreach programs to continue to develop context-specific, locally informed programs and support that align with RRR communities' values and ways of life.

This paper constitutes a jurisprudential study on motivación
in public procurement. The statement of reasons is an essential requirement,
whose lack leads to the annulment of the challenged act, although its effects are
usually limited to the retroaction ot the procedure so as to carry out a sufficient
reasoning. The motivation can be based on the technical reports that support the
administrative resolution.

Currently, the vast range of helminthoses of farm fish and animals is causing significant economic damage. Effective prevention is an important element in the fight against these diseases. An effective method of preventing helminthosis is the destruction by chemical means of shellfish - intermediate helminth hosts. Molluscocidal properties have decoction from leaves, stems and roots of medicinal soap (Saponária officinalis). The article describes the peculiarity of the procedure for preparing a molluscocide agent from this plant by cold alcohol extraction (maceration). The work used dried collection of roots, leaves, stems, flowers and soapwort seeds of medicinal S. officinalis, which was ground in a mortar to form powder (particle sizes 1... 3 mm). The powder was placed in a vessel of fermenter BioFlo to which 96% ethyl alcohol was added (1 g of dried collection per 100 ml of liquid). The speed of the impeller was 150 rpm. Inside the vessel, the temperature was 25 ± 2 ° C. The extraction process was carried out for 24 hours.The proposed technology enables to obtain a substance having high selective toxicity to mollusks. Its use in the form of a 1% solution causes the death of lymnaeids within 24 hours in the treated area. In the future, based on the obtained extract, it is possible to create a prophylactic molluscocide preparation that is inexpensive to manufacture and has low toxicity to humans and animals.

O presente trabalho tem a finalidade de refletir acerca da crise atualmente vivida pelo sistema carcerário brasileiro e suas semelhanças com as violações praticadas aos direitos fundamentais na Idade Média. Quanto à metodologia, neste trabalho foi utilizada a pesquisa bibliográfica, desenvolvida a partir da análise de livros e artigos científicos, bem como da pesquisa documental, tendo sido analisada ação judicial em tramitação na corte suprema brasileira. Verificou-se a nítida inobservância pelo Estado brasileiro do dever de cuidado com o sistema prisional pátrio como um todo, o que tem causado um quadro generalizado e duradouro de violação sistêmica de direitos. Essa falha estrutural causada pela omissão de entes políticos eleitos fez o Poder Judiciário declarar a existência no Brasil de um Estado de Coisas Inconstitucional, ficando autorizado a adotar medidas de coordenação de forma a formular políticas públicas com o objetivo de enfrentamento da calamidade estatal, visando à satisfação do direito de toda coletividade afetada até que a situação seja revertida.

Proton Exchange Membrane Fuel Cell (PEMFC) generates electricity through the reaction of hydrogen and oxygen. PEMFC is considered clean technology since the by-products of the reaction are only electricity, water, and heat. Thermal management of PEMFC can be further improved through the adoption of nanofluids as its cooling medium. Nanofluids are fluids that contain suspensions of nanoparticles in their base fluid. Nanofluids have better heat transfer performance as compared to their base fluid due to their significant thermal conductivity improvement. However, unlike any other heat transfer application, there is a strict limit on the electrical conductivity of the nanofluids due to their electrically active environment. Therefore, there is a possible current leakage to the coolant due to the nanofluids’ conductive behavior. In this study, heat transfer performance and current drop of 0.5% Al2O3 and 0.5% SiO2 water were investigated. The nanofluids were forced to flow in a charged channel subjected to a heater pad of 60°C to 70°C to mimic the operating condition of a PEMFC. The performance of each nanofluid was observed and compared to distilled water. The channel temperature was reduced by 43.3 % and 42.7 % by Al2O3 and SiO2 nanofluids, respectively, compared to base fluids at Re 700. In terms of current drop, SiO2 nanofluids have the highest current drop with 2.33 % from the initial current value. It was further justified with the increment in electrical conductivity value of the fluids after the experiment, thus justifying the current leakage hypothesis.

A mobile application to monitor heart rate (HR) during an exercise called Chromozone was developed to enable a user to regulate exercise intensity using a color-coded system rather than numerical display in the most conventional device. In this study, the agreement of HR from Chromozone was compared against the HR dataset from a clinically accepted electrocardiogram (ECG) on different exercise intensity and to assess its reliability by intra-day repeated assessments. Additionally, the usability aspect of the Chromozone smartphone application was also assessed. Forty-two participants underwent self-selected exercise intensities (based on individual HR reserve) included for 5-min followed by a cool-down period (3-min). A 20-min rest period was given to the participant before repeating the same exercise protocol two more times. Chromozone was found to generate excellent criterion-concurrent validity (r = 0.998, p < 0.001) and acceptable bias of 1.96 bpm (Limits of Agreement; LoA: 3.07 to -3.51) for relative and absolute agreement, respectively. Similarly, relative (intraclass correlation coefficient test: 0.998, p < 0.001) and absolute (within-subject coefficient of variation: 1.95 ± 1.4%) reliability using Chromozone application shows an excellent consistency. Additionally, this study also showed that the usability level of the Chromozone application is beyond the satisfactory level. The outcome of this work provides strong support for Chromozone application as a valid and reliable exercise HR monitoring tool that could potentially help athletes, active individuals as well as the clinical population to monitor and regulate their exercise training regime more effectively.

Astroviruses have been associated with enteric and extra-intestinal disorders in many animal species, including chickens. Here, we describe the detection and characterisation of chicken astrovirus (CAstV) in broilers and its seroprevalence in broiler breeder flocks. Based on PCR protocol, viral confirmation was carried out on clinical tissue samples from broiler chickens suffering from uneven growth and poor performance. The tissues were molecularly detected for CAstV with differential diagnostic testing against the Newcastle disease virus, infectious bronchitis virus, avian nephritis virus, avian rotavirus, fowl adenovirus and avian reovirus. Polymerase gene-based phylogenetic analyses of the twenty samples detected positive for CAstV indicate they belong to Group I and are related to strains from the US, UK, India and Poland. From these 20 samples, CastV could be isolated from 3 samples upon inoculation in 5-day-old specific-pathogen-free (SPF) embryonated chicken eggs (ECE); virus-infected embryos showed dwarfing, haemorrhages, oedema and gelatinous lesions at harvest. The enzyme-linked immunosorbent assay (ELISA) results revealed a high prevalence of antibodies against CAstV amongst the broiler breeder flocks tested. It is the first study that describes the detection and prevalence of CAstV in broiler chickens and broiler breeder flocks in Malaysia.
