Implementation of In-Silico Drug Design to Find Natural Product-Based SARS-CoV 2 Spike Protein Inhibitor
Authors: Sanyal Saptarshi , Banerjee Priyanka
Published: August 2023

COVID-19 has been a threat to the whole world due to its massive amount
of infectivity. The causative SARS- CoV virus has an extremely small biological
footprint. However, it has the ability to bind with the host cell, which, in this case, the
human upper respiratory tract, with the intervention of a minimal amount of enzymes
and energy. For this anchoring, this virus uses a specially designed protein known as
the spike protein or S-protein which also gives the virus its unique shape.
Unfortunately, even after the discovery of the vaccine, the number of people getting it
is still significant. This is due to the ability of the virus to prevaricate immunity through
constant mutation. Therefore, the search for an antiviral drug is still necessary. While
there are only a few identified targets of anti-SARS-CoV drug designing, the S-protein
can be unique for two reasons; first, it can be both virostatic and can be used as a post.exposure prophylaxis measure. Here, in this book chapter, we look into several drug.designing techniques that can be utilized for designing a molecule that can prevent the
first stage of infection, and that is to attach with the ACE receptor of the host cell using
the S-protein. Both ligand-based and structure-based designs have been taken into
consideration, with a special focus on lead molecules obtained from natural products.

Vatarakta : An Ayurvedic classical literature review
Authors: Soni Savitri
Published: July 2023

The statement “The inequalities of basic constituents in the body are the root cause for different diseases” is the fundamental principle of the Ayurveda, which indicate the control of different fundamental elements in the body (Sharira) is the sign of good health and free from diseases. Ayurvedic remedies and therapies are found very effective and useful to sustain the equilibrium of these fundamental elements in the body. Vatarakta is a chronic joint and body pain disease accompanied by pain, stiffness, swelling over joints which involve vitiated Vatadosha as well as Raktadhatu. Aggravated Vata is blocked by vitiated Rakta, which leads to further aggravation of Vata Dosha. Vatarakta have two Avasthas i.e., Uttana and Gambhira. Uttana Vatrakta affects Twacha and Mansadhatu whereas Gambhira mainly affects Asthi, Majjadi Gambhira Dhatu. Nidan Panchak is one of the finest and important method of diagnosing disease, its causes & prognosis. Nidan Panchak consists of 5 components viz. Nidan, Purvarupa, Rupa, Upshaya & Samprapti. Every component of Nidan Panchak helps the physician for better understanding of disease growth & treating the disease at an earliest possible stage. Nidana Panchak is the main and important diagnostic tools in Ayurveda. The present life style not only disturb the healthy Aahar but Vihara also. Sedentary lifestyle along with mental stress, consumption of nonveg and highly protein diet, excessive alcohol intake are some of the causing factors which origins acute exacerbation of Vatarakta. The etiological factors responsible for Gouty arthritis, pathology and clinical features are quite similar to Vatarakta.

Published: August 2023

Fresh and clean water is an essential source of life. It can be supplied from the oceans, rivers, lakes, streams, and marshes. Nowadays, clean water availability has become a problem in several areas. Several problems usually occur, including the local ecosystem and air conditions, so they cannot be used properly. It is one area vulnerable to clean water availability. Meanwhile, UNESCO declares the community's right to clean water is 60 liters per person daily. This situation is the basis of research problems with the aim of (1) analyzing the problems and obstacles of the Nganti community towards water needs, (2) community responses to these problems and technology, and (3) the Nganti community strategies for now and future. The method used in this research was qualitative and descriptive. The key informants are the head of village, the head of the Clean Water Association, the head of Ngraho sub-district, the leader of community, and a survey of 40 Nganti-Ngraho residents. The data analysis used statistics descriptive and qualitative by using SMART method. The results show that the currently developed strategy was membrane technology, but the ultra-filtrated water was still turbid, requiring a more sophisticated membrane technology. The expected strategy is that local government institutions need to be directly involved to improve water quality.

Sub-Regimes of Air-Water Slug Flow Characteristics in Horizontal Pipes by Liquid Hold-up Model Correlated to Bubble Behaviours (LHmBb)
Authors: Prayitno Yosephus , Dinaryanto Okto , Deendarlianto  , Indarto
Published: August 2023

Sub-regimes of air-water slug flow in horizontal pipes have been characterized by a liquid hold-up model correlated to bubble behaviors (LHmBb). The LHmBB is composed of two sections which are the liquid hold-up model and bubble behavior investigations. The liquid hold-up model is developed based on the statistical analysis of the probability density function (PDF) to quantify the bubble distribution. The bubble behaviors are qualitatively investigated based on the high-speed camera and correlated to the quantified LH for the characterization of sub-regime of air-water slug flow. The LHmBB characterizes the sub-regime of air-water slug flow in a horizontal transparent acrylic pipe with an inner diameter of underwater and air superficial velocities of and, respectively. As a result, four sub-regimes are determined as Initially dispersed Bubbles (IdB), Low dispersed Bubbles (LdB), High dispersed Bubbles (HdB), and Dominantly dispersed Bubbles (DdB). The presence of bubbles determines the type of sub-regime by decreasing the number of bubbles and dispersing the bubbles mechanism. Moreover, the proposed LHmBb includes the correlation function to ease the prediction of the sub-regimes of air-water slug flow characteristics which leads to the enhancements of the two-phase flow pattern map in horizontal pipes.
De redes neuronales recurrentes a modelos de lenguaje: la evolución del PLN en la generación de textos
Authors: Maqueda Bojorquez David Emmanuel
Published: August 2023

En el presente texto haremos un breve repaso por la evolución del procesamiento de lenguaje natural y la generación de texto artificial. Desde la década de 1990, vieron la luz las primeras ideas sobre generación artificial de textos. En una primera instancia, las técnicas existentes resultaron insuficientes para resolver tareas, tales como la propia generación de textos, la traducción automática o la búsqueda de información. Sin embargo, al pasar del tiempo se fueron generando nuevas ideas, con base en la comprensión propia de la generación de textos desde la naturaleza humana, desde los primeros modelos de redes neuronales recurrentes hasta los modelos de lenguaje más actuales, desde la consecución de palabras más básicas hasta lograr la generación de obras literarias enteras de manera artificial. De esta forma visualizaremos en esencia cómo es que se dio esta evolución en el campo y cuál fue la lógica que siguió.
¿Por el paraíso perdido?

Published: August 2023

As in Baudelaire's essays, artificial paradises, well-used drugs such as opium can stimulate a sense of well-being and absence of pain. Although with the risks of dependence, intoxication and even death, the need for powerful painkillers has led to the production of synthetic drugs of easy manufacture and low cost such as fentanyl that in the wrong hands, for illicit purposes and without specialized medical supervision, are a deadly weapon. Is it worth taking the risks looking for paradise lost?

Authors: Chávez-Martínez Emmanuel A. , Martínez Cabrera Daniel , Padilla-Estrada Claudia S. , Hernández-Martínez Hugo E. , Ochoa- Madrigal Marta G.
Published: August 2023

Background: Systemic lupus erythematosus is a chronic mul tisystemic autoimmune disease with diverse clinical mani festations. Women are the most vulnerable population and have the greatest neurological involvement with a higher risk of seizures. Neuropsychiatric manifestations occur in early stages of the disease and diagnosis since they can occur together with systemic manifestations or not. The frequency of neuropsychiatric manifestations in systemic lupus erythe matosus has been described from 14 to 75%; being cognitive alterations one of the major symptoms to highlight. Which, in the same way can be accompanied by affective disorders such as depression and anxiety. Since psychosis, secondary to SLE, stands out for its low prevalence (10%), laboratory studies usually guide us towards a definitive diagnosis, being ribosomal P antibodies the ones that have been more spe cifically related to lupus psychosis. MRI is the test of choice and brain lesions are dominated by punctate white matter hyperintensities. In the following case report, we present a 20-year-old pa tient who had a history of diagnosed hepatic steatosis, MODY type diabetes and resection of the right ovary for mature teratoma of 9 years of evolution; but with no psychiatric his tory of importance at the time of her evaluation. However, she acutely presented a psychotic outbreak characterized by delusions of grandiosity and reference; as well as behavioral, cognitive, and affective alterations. For which she had to go to a 3rd level hospital during the period of health contin gency in 2020. After a history of SARS-CoV-2 infection three months before her neuropsychiatric pathology, neurological symptoms secondary to COVID-19 infection were suspected, as well as isolated psychiatric pathology. Therefore, a study approach of the first psychotic outbreak was performed, diagnosing systemic lupus erythematosus with neuropsy chiatric manifestations. Treatment was based on a bolus of methylprednisolone and antipsychotics; later modified by therapy with oral corticosteroids and depot antipsychotic. Conclusion: Systemic lupus erythematosus with neuropsy chiatric manifestations is an infrequent presentation of the disease, because of the wide variation in its appearance, pa tients with psychiatric symptoms in a general hospital setting should be considered for extensive approaches. In the same way, having this knowledge of this case may broaden our knowledge about the complications of this rheumatologic pathology. And one of its most serious complications such as lupus psychosis to be able to make a better approach to the first psychotic outbreak in general hospitals, where the assessment of a specialist can be more complicated.

Objectives The purpose of this study was to identify changes in information literacy, self-regulation, and online learning effectiveness of adult learners, and to explore the structural relationship between the three variables. Methods A potential growth model was used by using data surveyed in 2014 (9th), 2016 (10th), 2018 (11th), and 2020 (12th) of the Korean Education Longitudinal Study 2005 (KELS 2005). The trend of change over time and the longitudinal relationship was verified. Results As a result of examining the trend of change over time, the average of information literacy, self-regulation, and online learning effectiveness did not change significantly, and the average of online learning effectiveness was relatively high. In addition, both information literacy and self-regulation statically predicted the initial value of the online learning effectiveness, and the rate of change was also significantly predicted. Finally, it was found that information literacy was greater than self-regulation in terms of the influence on the longitudinal change of online learning effectiveness. Conclusions Discussions and suggestions were presented on the significant effects of information literacy and self-regulation on the longitudinal changes in online learning effectiveness of adult learners. To ensure stable online learning effectiveness, prior training to improve competencies such as information literacy and self-regulation is required from the beginning, and support is especially required so that learners can acquire and adapt to new technologies. Through the results of this study, it will be possible to seek ways to develop information literacy and self-regulation skills to increase the effectiveness of online learning in a situation where the importance and application fields of online learning are expanding.

Published: July 2023

Poverty alleviation has become one of Indonesia's Sustainable Development Goals (SDGs) targets to be achieved by 2030, with poverty placed as a primary focus in national development. This study aims to compare the empowerment processes undertaken by  “Gerakan Ayo Kita Peduli “ and  “Pusat Kesejahteraan Sosial “ (Social Welfare Center, Puskesos) in Husein Sasatranegara, Bandung. The research employs a qualitative approach with a comparative model. The findings indicate that  “Gerakan Ayo Kita Peduli “ is more effective in providing empowerment due to its targeting of priority groups such as the elderly, orphans, and micro, small, and medium-sized enterprise (UMKM) practitioners. The program also enhances community capacity through the establishment of  “Tokopeduli. “ On the other hand,  “Puskesos “ carries out planned activities through neighborhood deliberations (musyawarah kelurahan), but it has not effectively improved living standards due to limited human resources. Both initiatives can conduct evaluations and implement improvements to achieve more effective empowerment.  “Gerakan Ayo Kita Peduli “ should strengthen the educational aspect, while  “Puskesos “ should enhance collaboration and community involvement.

Under global climate change, the temperature and precipitation on the
Tibet Plateau have significantly changed, and the melting of glacier and
snow has been also affected, subsequently causing changes in runoff. The
assessment of runoff and its components on the Tibetan Plateau under
climate change is important for water resources management and ecology
conservation in alpine regions. Therefore, the Spatial Processes in
Hydrology model (SPHY model), a distributed cold-zone hydrological model
which contains a glacial ablation module and performs well in alpine
region, was used to simulate runoff in the Yangtze River source located
in the middle of the Tibetan Plateau during 2000-2020. The input data
included the measured runoff from the Zhimenda hydrological station,
meteorological data from 16 meteorological stations, digital elevation
model (DEM) data, land use data and glacier data. And the coupled model
intercomparison project 6 (CMIP6) climate model was used to predict the
runoff process for the future 30 years (2020-2050). The results showed
that Nash-Sutcliffe efficiency coefficient (NSE), Relative Error (RE)
and coefficient of determination (R ) in Zhimenda
hydrological station for the calibration period, reached 0.900, 0.036
and 0.956, respectively, and NSE, RE and R reached
0.828, 0.120 and 0.924, respectively, for the validation period, which
shows that the model performed well in most years. In 2000-2020,
rainfall runoff contributed most to the total runoff (60.87%), followed
by baseflow (22.96%), snowmelt runoff (11.59%) and glacier runoff
(4.58%) in the Yangtze River source. The runoff amount of the three
source river, Dangqu River, Tuotuo River and Chumar River accounted for
about 53% of the total runoff in the Yangtze River Source basin, with
rainfall runoff (52.04%) contributing the most and glacier runoff
(5.92%) contributing the least. Compared to the contribution of glacial
runoff in the Dangqu River (8.87%) and Tuotuo River (6.59%), the
proportion of glacial runoff in the Chumar River was very small
(0.89%). Under the CMIP6 climate model, the mean runoff depth was
predicted to increase approximately 13.5 mm from 2020-2050 compared to
2000-2020.
Organic carbon content in the particulate matter emitted by rural soils. A laboratory assessment.
Authors: Mendez Mariano , Haberkon Nancy Belén Ramirez
Published: August 2023

The aim of this study was to assess the organic carbon (OC) content in
the PM10 emitted by agricultural soils and rural roads under controlled
conditions. Samples were collected from agricultural soils and rural
roads. The PM10 was generated and collected using an electrostatic
precipitator coupled with the Easy Dust Generator (EDG). This procedure
ensures that the PM10 collected come specifically from soil. OC contents
were measured in both the soil and PM10. The enrichment ratio (ER) was
calculated as the ratio between OC content in the PM10 and OC content in
the soil. The results showed that OC content in the PM10 ranged from 2.7
to 3.5 % in agricultural soils and from 1.4 to 2.9 % in rural roads.
These values were comparable to the OC contents observed in fine
particles transported by the wind, but lower than OC contents observed
in PM10 samples collected in rural areas using active samplers and
filters. A quadratic function described the association between OC in
PM10 and OC in the soil. A negative potential function described the
association between ERs and OC in the soil. Both associations suggested
a saturation of OC in PM10 when the OC content in the soil was high.
This information is crucial for a better comprehending of the dust
emission role in the redistribution of OC within terrestrial ecosystems
and to the atmosphere and oceans.

The study of natural suitability of human settlements environment aims
at objectively revealing the human settlements under the influence of
natural geographic elements, which to quantitatively characterize the
pattern of regional population distribution under natural limitations or
suitability. Based on the kilometer grid, the study establishes the
Human Settlements Index (HSI), which includes Relief Degree of Land
Surface (RDLS), Temperature-Humidity Index (THI), Land Surface Water
Abundance Index (LSWAI) and Land Cover Index (LCI). The main conclusions
are as follows: (1) The RDLS of Qinghai-Tibet Plateau is dominated by
high values (high elevation, sharp topographic undulation), with great
regional differences. It is obviously different that the THI of the
region, which shows an increasing trend from the northwest arid region
to the southeast. However, both the high LSWAI and the LCI distribute on
intensively and zonally. (2) Supposed that the auxiliary elements
(hydrology, vegetation) enhance dominant elements (topography, climate),
the conclusion shows that the HSI between 0.07~1 in the
study area, averages 0.45. According to the grading judgment of the
topographic and climatic suitability, with the restriction of
physiological elements on human habitation, there defines the 7 types of
human settlements environment suitability. (3) The unsuitable type
account for 32.48% of the total area, and only 1.87% of the
corresponding population, mainly distributed in the Kunlun mountains,
the Gangdis mountains and the western side of the Himalayas. As an
important basis, human settlements suitability provides scientific basis
for resources and environment carrying capacity, moreover, it supports
the regional planning and population distribution.

Published: August 2023

The aim of this research is to study the bactericidal effects of copper?polypyrrole (PPy) composites deposited onto 316L stainless steel (SS) modified with silver nanoparticles (Np). The antimicrobial properties were evaluated against twenty-four strains of Gram-positive and Gram-negative bacteria. Among the twenty-four strains studied, isolates included reference strains (Escherichia coli ATCC 25922, Escherichia coli 0157:H7 EDL 933, Staphylococcus aureus ATCC 25923 and Listeria monocytogenes ATCC 7644), as well as strains isolated from food and clinical samples. The antimicrobial activity of the composites demonstrated that all PPy-modified films had antibacterial properties. Notably, Cu-PPyAgNp500 exhibited the strongest inhibitory activity against both Gram-negative and Gram-positive bacteria. Surface modification of 316L SS with these films is a promising and viable alternative for the development of novel antibacterial composites that can inhibit the growth of a significant number of bacteria.

Published: August 2023

In order to investigate the impact of cooling plate channel structural parameters on the cooling performance of battery modules, a heat generation model for LiFePO4 batteries was established. Based on the model, the 1C discharge process of LiFePO4 batteries at room temperature (25?) was simulated, and relevant heat release data were obtained. On this basis, three different cooling plate structures (Model A, Model B, Model C) were designed, and the cooling performance of the cooling liquid (50% water and 50% ethylene glycol) for the battery module was analyzed by simulation at different mass-flow rates (0.15 kg/s, 0.18 kg/s, 0.21 kg/s), along with the pressure, temperature difference and flow rate of the cooling channel. The results showed that the uniformity of the flow rate in the channel can reduce the temperature difference. Under the same mass-flow rate, the temperature difference of the battery module on the same surface between Model A and Model C was 1.1?, but too many channels would increase the pressure drop. The pressure drop of Model C was more than 10 times that of Model B. Therefore, it is necessary to design the channel structure reasonably while ensuring the heat dissipation effect. Finally, based on the simulation results, beneficial suggestions for the cooling and cooling plate design and manufacture of energy storage container battery modules are proposed.
Heat transfer comparison investigation of the permanent magnet synchronous motor for electric vehicles based on the BEM and the FEM
Authors: Zhang Jiacheng , Zhang Haixu , Liu Zining
Published: August 2023

In the field of heat transfer in permanent magnet synchronous motors (PMSM) for electric vehicles, the boundary element method (BEM) has been applied for the first time to calculate the steady-state temperature of the PMSM with a spiral water-cooled system. In this investigation, the boundary-integration equation for the steady-state heat transfer problem of a water-cooled PMSM is first derived on the basis of thermodynamic theory, and the system of constant coefficient differential equations is obtained by discretizing its boundaries, while the temperature results obtained from the BEM are compared with the finite element method (FEM) results. Furthermore, the temperature distribution and heat transfer characteristics obtained from the FEM and BEM were verified twice using the PMSM prototype and test platform. The results show that the maximum relative error between the temperature calculation results of FEM and BEM is 1.97%, and the maximum relative error between the results of BEM and the test does not exceed 3%, which finally verifies the validity and accuracy of BEM in solving the heat transfer problems of water-cooled PMSM.

Mental Health and Psychosocial Support is a mental health effort for disaster survivors. Psychiatric nurses have competence in conducting it in every disaster situation. A refuge is a place for community service activities for mental nurses. Earthquake survivors who live in evacuation shelters are among the vulnerable groups experiencing mental health problems. There is a risk of mental health problems and survivors' psychosocial well-being requiring intervention from nurses. Mental health and psychosocial support by nurses can detect and prevent mental health problems and increase survivors' mental health resilience. Community service activities for natural disasters in Cianjur aim to detect early mental health problems and improve knowledge and skills in managing stress. Activities carried out in the form of group and individual mental nursing interventions. The method used is detecting mental health problems using the Self Report Questionnaire-20 (SRQ-20), providing health education through lectures, discussions and training skills regarding stress management. Activities were carried out in 4 batches and - each batch for two days. The number of survivors aged 18 and over who were intervened was 418 people from 4 villages in Cianjur Regency. The results of the SRQ-20 measurement show that 70.1% of survivors experience mental and emotional disorders. Evaluation of activities orally survivors could answer questions and demonstrate the stress management method given. Mental health and psychosocial support (DKJPS) is a standard mental nursing intervention in disaster mental nursing care. DKJPS can be applied to the practice of disaster mental nursing collaboratively by involving various scientific disciplines of nursing in the disaster area.
