Published: June 2022

Introduction: Health care workers act as front-line heroes during the pandemic, but during this period, they are facing problems from the society and families as everyone is thinking they are carriers of the disease. Such an unfavourable situation can develop bad social behaviour, social loneliness, social isolation, anxiety, fear, sadness, anger, frustration, and low esteem towards work, because of the fear of infection.Objectives: The study was conducted to assess the social challenges faced by COVID-19 warriors posted at a COVID-19 care unit and to seek the association between social life challenges faced by them and selected demographic variables.Methodology: The quantitative approach using a descriptive research design was incorporated to conduct the study. 60 COVID-19 warriors posted at a COVID care unit were selected using purposive sampling. The tool used for conducting the study was a rating scale to assess the social challenges faced by them. Online Google survey forms were distributed to samples using their e-mail ids. Result: For data analysis, descriptive and inferential statistics were used. The study shows that 58.3% experienced bad behaviour from society (Figure 1 and Table 2), 55.0% experienced severe social loneliness (Figure 2 and Table 2) and 25% experienced moderate social loneliness (Figure 2 and Table 2). 61.67% of study subjects were severely anxious (Figure 4 and Table 2) and 76.7% were in severe fear (Figure 5 and Table 2). There exists a statistically significant association between social challenges and selected demographic variables (Table 3).Conclusion: The study concluded that COVID-19 warriors posted at a COVID care unit experienced social challenges associated with their demographic variables.

Authors: Bauck Anje G. , Vidyasagar Sadasivan , Freeman David E.
Published: June 2022

OBJECTIVE

To examine bicarbonate (HCO3−) secretion ex vivo in the equine large colon to determine any differences between the right dorsal colon (RDC) and right ventral colon (RVC). The effect of phenylbutazone (PBZ) on HCO3− secretion was examined in the RDC.

ANIMALS

14 healthy horses.

PROCEDURES

In anesthetized horses (n = 10), segments of mucosa from RDC and RVC were harvested to measure HCO3− secretion ex vivo with the pH Stat method. The effect of PBZ on HCO3− secretion in the RDC was studied in 4 additional horses.

RESULTS

Three distinct mechanisms of HCO3− secretion previously described in a murine model were confirmed in the equine colon. The RDC had a greater capacity for electrogenic, Cl−-independent HCO3− secretion than the RVC (P = 0.04). In the RDC, all HCO3− secretion was decreased by PBZ (P < 0.02) but was not studied in the RVC because of low baseline secretion.

CLINICAL RELEVANCE

Secretion of HCO3− by the RDC could play a pivotal role in equine colon physiology, because intense microbial fermentation in this site could require HCO3− secretion to buffer short-chain fatty acids. Inhibition of this secretion by PBZ could interfere with mucosal buffering and predispose to changes associated with right dorsal colitis.
Lipases: it's not just pancreatic lipase!
Authors: Lim Sue Yee , Steiner Jörg M. , Cridge Harry
Published: June 2022

Lipases are water-soluble enzymes that hydrolyze water-insoluble lipid molecules, such as triglycerides, phospholipids, and galactolipids. They are ubiquitous in nature and are present in humans, animals, insects, plants, fungi, and microorganisms. While we commonly consider pancreatic lipase, this review provides an overview of several lipases that are important for the digestion and metabolism of lipids in veterinary species. All of these enzymes have specific functions but share a common α/β-hydrolase fold and a catalytic triad where substrate hydrolysis occurs. The pancreatic lipase gene family is one of the best characterized lipase gene families and consists of 7 mammalian subfamilies: pancreatic lipase, pancreatic lipase related proteins 1 and 2, hepatic lipase, lipoprotein lipase, endothelial lipase, and phosphatidylserine phospholipase A1. Other mammalian lipases that play integral roles in lipid digestion include carboxyl ester lipase and gastric lipase. Although most enzymes have preferred substrate specificity, much overlap occurs across the plethora of lipases because of the similarities in their structures. This has major implications for the development and clinical utilization of diagnostic assays. These implications are further explored in our companion Currents in One Health article by Lim et al in the August 2022 issue of the Journal of American Veterinary Medical Association, which focuses on pancreatic lipase assays for the diagnosis of pancreatitis.

Published: June 2022

Platelets play an important role in fracture healing. However, its role is still underappreciated. Therefore, this study investigated the values of mean platelet volume (MPV) and platelet count (PC) as the parameters in fracture healing. This study used 10 male local rabbits which were divided into 2 groups randomly, KI (control group) and KII (treatment group). Each femur of both groups was drilled a hole with a diameter of 5 mm, where KI without any substitutes and KII was implanted by demineralized bali cattle bone graft. Each animal was evaluated by collecting its blood from the central auricular vein into an EDTA tube at 24 hours, week 2, 4, and 6 postoperative determining the values of MPV and PC. Results show that treatment shows no differences to MPV and PC, yet time observation does. Overall, MPV and PC were increased in number during observation and are correlated positively.

Revitalization of the Seattle Waterfront
Authors: Wong Chelene , Valdovinos Schaun , Lee Barbara
Published: June 2022

The demolition of the 3.5-km Alaska Way viaduct opened doors for City of Seattle to transform its waterfront district. The overhead, double-decker freeway along the waterfront obstructed views of Puget Sound from the downtown and generated significant noise pollution. The structure cast wide shadows so the cold, barren nature of the ground-level space left it to be unusable for all but parking. Now torn down, people have a new visual connection with Puget Sound from downtown. This has opened opportunities to knit together the reimagined waterfront with the downtown core and to the historic Pike Place Market.

The new Union Street Pedestrian Bridge is one such opportunity, providing a safe, universally accessible east-west connection for residents, workers and visitors of Seattle. The bridge is a key element of the revitalization of the neighborhood.

The sculpted form of the bridge uses an elegantly haunched cast-in-place concrete girder and sculpted columns to carry pedestrians out over the hardscape below as an extension of the upper sidewalk. This becomes a skywalk as users approach the waterfront promenade from an elevated perspective. A grand staircase and elevator provide vertical circulation from the bridge deck down to lower grade. Two artwork elements are incorporated into the design – a decorative screen wall along one edge of the bridge, and a 21m long stainless-steel sculpture of a giant fern frond that arches over the staircase. The frond is supported at the top end on the 18m high elevator tower that is glazed in channel glass which will glow like a lantern at night. The overall effect of the interacting features is dramatic and will create a beacon to help with wayfinding along the waterfront promenade.
The Early Criminal Record on the Boundary of Entertainment: Thomas F. Byrnes’ Professional Criminals of America and the Spectacle of Criminal Identification
Authors: Brackett Charles
Published: June 2022

While the proliferation of criminal records has received much recent attention, the origin of the criminal record in the United States itself is relatively obscure. This article examines an episode in the development of criminal record keeping and lateral surveillance in the United States, the publication and reception of Thomas F. Byrnes’ Professional Criminals of America ([1886] 1969). I argue that Professional Criminals of America developed a cultural purchase well beyond its relatively modest circulation. By exploiting anxieties about mobility, anonymity, and the decline of class distinction, Byrnes’ book sold itself as a tool to develop regimes of lateral surveillance, enlisting regular citizens to support the police by spying on one another.

Authors: Savelyeva M. V. , Gudz’ Yu. V.
Published: June 2022

Relevance. In terms of environmental and social dimensions, the Chernobyl accident is the largest in the history of Russia. Radiation-hazardous incidents also occurred on nuclear submarines. The leading medical consequences of various radiation accidents in the remote period were the presence of psychosomatic pathology among the liquidators of the consequences of accidents. Intention. To determine the leading factors of psychological status among liquidators of the consequences of radiation accidents, which mitigate the development of psychosomatic disorders in the long term. Methodology. In 2019, a comprehensive in-hospital examination of 101 male liquidators of the consequences of the accident at the Chernobyl nuclear power plant was conducted. The examined persons were (65.2 ± 0.7) years old, the average radiation dose was 18 cSv. All surveyed liquidators had somatic pathology with an important contribution of psychogenic factors (hypertension, metabolic syndrome, diabetes mellitus, gastric/duodenum ulcer etc.). The psychological status was assessed using well-known tests. As a control, we used the reference indicators of the methods for similar gender and age groups. The information obtained was checked for normality of distribution. Arithmetic mean values and their errors (M ± m) are provided. Using the factor analysis with rotation of the array, the factors of psychological status were established. Results and Discussion. It turned out that the liquidators of the consequences of the accident have lowered indicators reflecting an active life position and quality of life. When the respective accident was mentioned, they showed irritability, a feeling of tension and alertness, which indicated their anxiety-phobic experience even in the remote period after the accident. Interest in life, its emotional saturation, and self-confidence were decreased. At the same time, indicators of manipulative and antisocial actions were lower vs the control group. In the factor analysis of psychological indicators using principal components with rotation, 5 factors were formed with a total variance of 58.6 %. Factors with higher association contained psychological signs that contributed to or mitigated psychosomatic disorders as follows: Factor 1, named as “Active life position”, accounted for 31.3 % of the total variance; Factor 2 “Negative socio-psychological consequences of a radiation accident” - 10.1%; Factor 3 “Quality of life” - 8.1 %; Factor 4 “Non-constructive models of behavior in a difficult life situation” - 4.9 %; Factor 5 “Mental health” - 4.1 %. Conclusion. The factor analysis of the results from liquidators of the radiation accident helped identify the leading positive qualities and maladjustment problems that can be targets for psycho-prophylaxis.

Acute lung and lower respiratory tract damage after inhalation exposure to hydrogen fluoride
Authors: Sheianov M. V. , Parinov O. V.
Published: June 2022

Relevance. Hydrogen fluoride is a highly active chemical substance widely used in industry for production of inorganic fluorides, organofluorine compounds, in the processing of aluminum, stainless steel and alloys. The chemical properties of hydrogen fluoride determine its ability to have a destructive effect on the tissues of the human body and high toxicity with local and systemic exposure. Hydrogen fluoride poisoning is severe and difficult to treat. Clarification of the clinical picture and the search for new methods of treating lesions with hydrogen fluoride are of great importance for protecting the health of workers in chemical industries and eliminating the consequences of technogenic accidents.Intention. To consider the features of the observed clinical case of severe damage to the lungs and lower respiratory tract after inhalation exposure to hydrogen fluoride and treatment methods that made it possible to achieve favorable clinical results. Methodology. The article discusses clinically important chemical properties of hydrogen fluoride, the mechanisms and manifestations of characteristic lesions developing in the human body with various routes of exposure. Modern approaches to the treatment of patients exposed to hydrogen fluoride are outlined.Results and Discussion. Inhalation of gas mixtures, even with low concentrations of hydrogen fluoride, can lead to severe inflammatory-necrotic lung damage with interstitial pneumonia (chemical pneumonitis), adult respiratory distress syndrome, and severe respiratory failure. Improvement of clinical condition of the affected person in the observed case was achieved via complex treatment with glucocorticosteroids, antimicrobial agents, calcium gluconate inhalations. A key role in the patient’s treatment was played by long-term replacement of the impaired function of the lungs using extracorporeal membrane oxygenation.Conclusion. In severe forms of acute damage to the lungs and lower respiratory tract as a result of inhaled exposure to hydrogen fluoride, clinical recovery and improvement in the quality of life of the injured can be achieved through complex therapy using glucocorticosteroids, antibacterial agents, specific antidotes (calcium gluconate) and prolonged replacement of the respiratory function via artificial ventilation and extracorporeal membrane oxygenation.

Authors: Yunus Syukri , Latif Melda , Darwison Darwison
Published: June 2022

Placing the PV in the right location will maintain the utility voltage, but if the placement of PV in the wrong location will cause the stability of the system to be affected. In this study, optimization of PV placement uses the K-means Clustering method. This method will group each node in the system from the point of view of operating characteristics LSF (loss sensitivity factor) and dV (voltage deviation). The results of grouping each bus with the K-means Clustering method will be the basis for determining the location of PV placement in the IEEE 37 and 69 bus distribution systems. In this method, grouping results are used based on the size of the proximity and have the same characteristics with each other. In determining the optimal location for PV placement, the addition of PV will reduce power losses and improve voltage. Optimal PV location placement in the IEEE 37 bus distribution system is placed on 3 buses with a power capacity of 60% where the value of power losses drops to 176.2 kW and the voltage profile is the best but there are some buses that are still under voltage and overvoltage. Meanwhile, the most optimal PV location for the IEEE 69 bus distribution system is placed on a 6 bus with a power capacity of 60% where the value of power losses drops to 149.5 kW and the voltage profile of each bus is in normal condition..

Published: June 2022

Improving heat transfer using nanofluids has proven to be a promising option with many practical applications. However, the behavior of particles conveying energy for thermal transport depends closely on the dimensions of systems and channels where the flow evolves. Thereby, any fine thermal analysis should lean on a mesoscale approach applied at a microscale level. To this end, the multi-distribution functions–thermal lattice Boltzmann method has been taken to deal with convective heat flow and entropy generation in a channel with isothermal top–bottom walls and filled with a nanofluid (Cu/water). It was extended to simulate the flow governed by the Brinkman–Forchheimer Darcy model using the local thermal equilibrium assumption. The effects of nanoparticles’ volume fraction, Darcy number, porosity, heat capacity ratio and thermal conductivity ratio on heat transfer, entropy generation, average Nusselt number, and Bejan number are investigated. Among the salient results, it can be stated that the nanoparticles’ volume fraction increases heat transfer and entropy generation, but such a propensity can be affected by the porous medium permeability used. To sum up, the findings confirm the potential of the multi-distribution functions–lattice Boltzmann formalism to tackle forced nanofluid flows with heat transfer in porous media.

The results of determining the sorption properties of samples of combined fibrous materials impregnated with dispersions of water-soluble polymers of different types and concentrations filled with clay minerals in relation to the methylene blue dye are presented. The rational composition of dispersions of water-soluble polymers filled with clay minerals is determined. The obtained materials can be used as a reinforcing base of fibrous sorbents for their further use in the treatment of light industry wastewater from dyes and heavy metal ions.The aim of the work is to determine the kinetic regularities of sorption (by methylene blue) of combined fibrous materials impregnated with dispersions of water-soluble polymers of different types and concentrations filled with clay minerals. As a fibrous basis for the composite material used knitted fabric with a surface density of 240 g/m2, which was made of plaited weave using cotton yarn with a linear density of 25 Tex and polyethylene complex threads with a linear density of 16.5 Tex on a single-font circular knitting machine type MS. First, a dispersion of the clay mineral was prepared in an aqueous solution of a polymeric binder, which was then applied with a squeegee knife to the surface of the knitted material. The sorption properties of the samples were determined by the methylene blue dye, the change in optical density was measured on a UNICO 2150 E spectrophotometer, wavelength 600 nm, cuvette 10 mm. Calculated the degree of absorption of the dye from the solution after 24, 48 and 72 hours of treatment. It was determined that increasing the duration of sorption above 48 hours is not rational. The highest degree of absorption of MS is shown by samples of knitted material treated with 3% dispersions of PVA and starch,78.4 and 77.1%, respectively. This is probably due to the fact that these samples are characterized by the highest content of clay adsorbent, the weight gain for these samples after the introduction of clay adsorbent was 78.7 and 60.1%, respectively. In the case of the use of filled dispersions of CMC and CMS, a larger amount of clay adsorbent is characterized by samples treated with dispersions of CMC and CMC of lower concentration.

Rapid growth of information technologies causes the changes in many production processes. The effectiveness of elec-trotechnical means of infrared radiation is due to the application of new, scientifically grounded methods and means of energy supply control using controllers and personal computers, new information technologies and systems.Therefore, there is a need for further mathematical models development as well as information technology used in deci-sion support systems on infrared grain drying from elevators and granaries.Research and publication analysis on information support questions of grain drying based on infrared radiation technol-ogy has shown that the issues of information support systems are currently underexplored in scientific literature.The goal of this research is mathematical modeling of the IR grain drying process and information support development of the drying process, taking into account the obtained mathematical model.The improved model of the infrared drying process for grain crops is proposed, which, in contrast to the existing ones, is focused on application in decision support systems when organizing the drying process. The results of the experiments proved that infrared radiation use contributes to the intensification of the grain drying process due to a significant heat flux rate increasing on the material’s irradiated surface and the of infrared rays’ penetration into material. It has been proved that modern information technology, rational schemes and operating parameters of infrared grain drying processes utilization will reduce dehydration time with "gentle" drying modes to ensure the required quality parameters of the product.In this work it was first proposed to abandon probabilistic models of grain flow behavior under IR irradiation. A new mathematical model has been proposed based on information about the characteristics of the heat flow, dehydration and grain mass’ condition. This will significantly improve the IR grain drying process and get a higher quality product

That is why the development of methods and models for predicting the success of startup projects is significant.There is no research on using neuro-fuzzy systems for astartup success integrated assessment. This statement only em-phasizes the need to develop and implement such a system due to its undeniable relevance.Fuzzy systems are widespread in modern startup success forecasting models, but they have disadvantages like finding membership functions, the need for an expert to determine the rules and total adherence to the existing system rules. That iswhy the search for the possibilities to combine neural networks and fuzzy logic has become quite popular.Most of theexisting analysis and projects evaluation models use accurate data-based training, but it is not always possible to provide accurate startup data. The purpose of this research is to support decision-making in the creation of startup projects through the development of an automated information system for a comprehensive assessment of the startup success.A neuro-fuzzy information technology model for startup success level integrated assessment has been developed, consist-ing of 3 main subsystems. The data processing subsystem,subsystem of neuro-fuzzy assessment for projects, subsystem for searching for successful startup projects and selecting strategies for further startup development. The complex information system will allow you to get a success assessment, an individually formed strategy for project development, and use the experience of similar startups in the development.

Objetivo: Identificar os diagnósticos histopatológicos de Carcinoma de Vesícula Biliar (CVB) e colesterolose em produtos de colecistectomia eletiva realizadas entre janeiro de 2012 e dezembro de 2017, em hospital universitário. Métodos: Tratou-se de um estudo retrospectivo de análise de dados histopatológicos de produtos de colecistectomia eletiva por diagnóstico clínico de colelitíase. Os dados foram avaliados pelo software Epi-info. Resultados: Foram avaliados 1776 laudos, dos quais 7 apresentaram diagnóstico de CVB incidental, todos os pacientes eram do sexo feminino com idade igual ou superior a 35 anos. Foram ainda identificados 322 casos de colesterolose, em sua maioria associados a colecistite e com maior frequência também no sexo feminino. Conclusão: O CVB é de difícil diagnóstico em seu início, devido a sinais clínicos inespecíficos e semelhantes aos de colecistite. Não é raro o diagnóstico incidental através da análise histopatológica de peças de colecistectomia eletiva. Devido a agressividade do CVB reafirma-se a necessidade do diagnóstico precoce através das análises histopatológicas de peças cirúrgicas de colecistectomia eletiva por outros diagnósticos pré-operatórios.

Objetivo: Compreender a fisiopatologia da Síndrome de Alagille (SAG) e suas formas de tratamento. Revisão bibliográfica: A SAG é uma doença multissistêmica autossômica crônica rara, caracterizada pela escassez de ductos biliares interlobulares e por uma grande variabilidade clínica que envolve órgãos e sistema. Dados epidemiológicos demonstram que essa doença afeta cerca de 1 a cada 30.000 nascidos vivos. As mutações genéticas causadas pela SAG podem afetar os olhos, o coração, os ossos, a face e principalmente o fígado. Da mesma forma, a mortalidade varia em média de 10 a 20%, sendo que em casos de problemas ou transplantes hepáticos a variação é de 25%, problemas cardíacos 15% e hemorragia cerebral em 25% dos casos de mortes. A forma de tratamento consiste no uso de fármacos com associação de vitaminas lipossolúveis e, em casos mais graves, o transplante hepático. Considerações finais: O diagnóstico e tratamento devem ser tratados com bastante atenção juntamente com uma equipe multidisciplinar para um melhor prognostico para o paciente, assim oferecendo uma melhor qualidade de vida.

Objetivo: Expor o ponto de vista dos acadêmicos de medicina acerca da Relação Médico-Paciente (RMP) no ambiente de Pronto-Socorro Infantil e propor alternativas para sua melhoria. Relato de experiencia: O ambiente universitário oferece experiências para auxiliar na formação de médicos afim de aprender e lidar com situações adversas da rotina. Denota-se, que a forma de abordagem do paciente pediátrico, a comunicação verbal e não verbal durante o atendimento, associado aos demais fatores que regem a interação do profissional com o paciente e seus responsáveis, são de fundamental importância para a obtenção dos melhores dados médicos. Observa-se que independente do ambiente, quando o contato é realizado de maneira hostil, esse torna-se lesivo a qualquer um dos pilares da RMP e pode guiar de maneira indesejável a desfechos e repercussões negativas. Portanto, é de grande relevância o reconhecimento e atenuação dos obstáculos existentes entre a RMP, para assim conduzir um diagnóstico correto, tratamento adequado e satisfação dos que buscam os serviços médicos. Considerações finais: A comunicação correta com aquele que necessita de um serviço de saúde é habilidade médica fundamental. Logo, é de responsabilidade profissional estar atento a fatores que interferem negativamente na RMP, corrigindo-as a fim de prevenir desfechos desfavoráveis.

HPLC coupled to atmospheric pressure ionisation mass spectrometry has almost replaced HPLC assays with UV, fluorescence, or electrochemical detection, due to its enhanced speed, sensitivity, and selectivity, especially when tandem-MS is used. To increase the speed and sensitivity of the drug assays further, high-speed HPLC, multi-component analysis, and µHPLC are used on a routine basis. Sample preparation is recognized as an important issue in bioanalytics. The use of a 96-well plate format with automated liquid-handling systems, off-line and on-line solid-phase extraction or automated liquid-liquid extraction allows to cope with the high sample throughput enabled by LC-MS. Although LC-MS/MS represents the highest standard with respect to sensitivity and selectivity, LC-MS, as a less expensive alternative, is useful in many stages of drug discovery and development. CE-MS and CEC-MS appear to be an attractive alternative to HPLC-MS with respect to separation power, but both are a challenge in application and only seldomly used for the quantification of new drug candidates in biological fluids.
Exploration by Confidence
Authors: Borchmann Daniel
Published: June 2022

Within formal concept analysis, attribute exploration is a powerful tool to semiautomatically check data for completeness with respect to a given domain. However, the classical formulation of attribute exploration does not take into account possible errors which are present in the initial data. We present in this work a generalization of attribute exploration based on the notion of confidence, which will allow for the exploration of implications which are not necessarily valid in the initial data, but instead enjoy a minimal confidence therein.

Ontology-based data access (OBDA) generalizes query answering in relational databases. It allows to query a database by using the language of an ontology, abstracting from the actual relations of the database. For ontologies formulated in Description Logics of the DL-Lite family, OBDA can be realized by rewriting the query into a classical first-order query, e.g. an SQL query, by compiling the information of the ontology into the query. The query is then answered using classical database techniques. In this report, we consider a temporal version of OBDA. We propose a temporal query language that combines a linear temporal logic with queries over DL-Litecore-ontologies. This language is well-suited for expressing temporal properties of dynamical systems and is useful in context-aware applications that need to detect specific situations. Using a first-order rewriting approach, we transform our temporal queries into queries over a temporal database. We then present three approaches to answering the resulting queries, all having different advantages and drawbacks.
