Biomedical Waste Management
Authors: Khandelwal Gaurav
Published: August 2021

Bio medical waste (BMW) disposal is a very important yet a challenging task. Health care waste contains potentially harmful microorganisms, which can infect hospital patients, health workers, and the general public. Exposure to hazardous health care waste can result in disease or injury. The Government of India has been laying down rules, namely, Bio Medical Waste (Management and Handling) Rules, in 1998, COVID-19 pandemic and its consequent biomedical waste is an unprecedented challenge worldwide. Biomedical waste generated during COVID-19 patient isolation, testing and care needs special consideration as it challenges the previous notion that only 15–20% of waste can be considered infectious. With establishment of new home quarantine facility, isolation/quarantine centers the chances of general waste getting contaminated with biomedical waste has increased exponentially. The key step in COVID19 waste management is segregation of biomedical waste from solid waste. Waste generated from COVID19 patients is like any other infectious waste, therefore creating public awareness about the COVID19 waste hazards and segregation at source is highlighted in all guidelines as a recommendation.

Simulation Methods Development for an EV Battery Pack in Terms of Thermal and Safety Aspects
Authors: Shinganapurkar Neehar R.
Published: August 2021

This paper is the representation of our effort at modelling a LiFePO4 battery pack for an electric vehicle (EV) and further carrying out simulations on it. The process involves creating a single cell and then making a combination of these cells to form a battery pack. The simulations assist us in monitoring the thermal behaviour of the 60Ah battery pack after working for a stipulated amount of time at 1 and 2 C rates. It can be observed that the battery pack may experience thermal shock or thermal runaway leading to the failure of battery pack. Hence it is of paramount importance that we keep a check on the temperature range of the battery. The pack functions best when its temperature is maintained in the range of 288K-308K. This is a challenge in the absence of cooling. Hence, we used air and PCM (RT15 & RT31) as coolants to accomplish the objective of maintaining the temperature of battery pack within the optimum range.

O monolinguismo nacionalista do Estado Novo nas páginas da Revista de Imigração e Colonização
Authors: Castro Pedrina Barros de
Published: August 2021

Este trabalho tem como objetivo analisar a contribuição da Revista de Imigração e Colonização ao conjunto de ações implementadas pelo Governo Vargas no período do Estado Novo (1937-1945) de forma a disseminar e legitimar o nacionalismo no Brasil. Nesse contexto, a defesa do monolinguismo baseado na língua portuguesa era entendida como fundamental para se alcançar não só a união da população brasileira como a assimilação das comunidades de imigrantes. Dessa maneira, além das políticas autoritárias de restrição ao uso e ao aprendizado do idioma estrangeiro, realizadas diretamente pelo Governo Vargas por meio de leis, diversas outras políticas linguísticas foram desenvolvidas mediante a utilização do aparato estatal, com o objetivo de construção da identidade nacional, como a publicação da Revista de Imigração e Colonização.

Spatiotemporal impact of antecedent drought on hot extremes from the nonstationary risk perspective: A case study in eastern China
Authors: Xu Pengcheng , Wang Dong , Wang Yuankun , Singh Vijay , Qiu Jianchun , Wu Jichun , Zhang Along , Ju Xiaopei
Published: August 2021

Hot extremes may adversely impact human health and agricultural
production. Owing to anthropogenic and climate changes, the close and
dynamic interaction between drought and hot extremes in most areas of
China need to be revisited from the perspective of nonstationarity. This
study therefore proposes a time-varying Copula-based model to describe
the nonstationary dependence structure of extreme temperature (ET) and
antecedent soil moisture condition to quantify the dynamic risk of hot
extremes conditioned on dry/wet condition. This study proposed a new
approach to identify the soil moisture driving law over extreme
temperature from the point view of tail monotonicity and nonstationary
risk assessment. Owing to the LTI-RTD (left tail increasing and right
tail decreasing) tail monotonicity for dependence structure of these two
extremes derived from most areas, the driving laws of soil moisture over
ET follows DDL1-WDL1 laws (DDL1: drier antecedent soil moisture
condition would trigger a higher risk of ET; WDL1: wetter antecedent
soil moisture condition would alleviate the occurrence risk of ET).
Because of the spatiotemporal divergence of sensitivity index derived
from tail monotonicity (SITM), we can conclude that the spatial and
temporal heterogeneity of response degree of ET over the variations of
antecedent dry/wet conditions is evident. Incorporation of
nonstationarity and tail monotonicity helps identify the changes of
driving mechanism (laws) between soil moisture and hot extremes. From
the comparison of different kinds of nonstationary behaviours over the
spatial distribution of conditional probability of ET (CP1), the
dependence nonstationarity can impose greater variations on the spatial
distribution of conditional risk of ET given antecedent dry condition
(CP1).
A multiaxial prediction equation of low/medium/high cycle fatigue life of metallic materials for plain and notch components
Authors: yan xiangqiao
Published: August 2021

In this paper, it is important to illustrate that, for the LCF of
metallic materials, a “stress quantity” calculated based on the
linear-elastic analysis of the studied component is taken to be a
mechanical quantity, S, to establish a relation of the
mechanical quantity, S, to the fatigue life, N, is
practicable. Based on the practicability, a prediction equation, for a
low/medium/high cycle fatigue life assessment of metallic materials, is
proposed. The prediction equation is a stress invariant based one, in
which the computation of stress invariant is on the basis of the
linear-elastic analysis of the studied component. Using
experimental data of plain specimens reported in literature, it is
proved that the prediction equation is both accurate and high efficient.
In addition, the prediction equation in conjunction with the Theory of
Critical Distances and linear-elastic notch mechanics are
combined to establish the fatigue life estimation equation of the
notched components. Finally, using experimental data of the fatigue life
of 16MnR steel, validation verification of the notch fatigue life
prediction equation is given.

Published: August 2021

Introduction: A major focus in CF care aims to increase weight gain.
Rates of overweight and obese people with CF have gradually increased
over the past decade. Obesity could be a risk for restriction of lung
volumes and airway obstruction as well as increase rates of pulmonary
exacerbations in people with CF. Methods: Patients 6 years of age and
older were categorized into weight categories based on the CDC
definitions. A retrospective chart review was conducted to obtain lung
function testing and other outcomes. Results: 107 patients with a median
age of 20.6 years were included in this analysis. 8.4%, 64%, 18% and
10% of patients were underweight, normal/healthy weight, overweight and
obese respectively. FEV1 and FVC (% predicted) did not differ between
patients with weights in the normal range vs. patients in the
overweight/obese categories. Linear regression analysis showed a direct
correlation between BMI and FEV1 that continued as BMI entered
overweight and obese categories in both pediatric and adult patients.
Overweight/obese patients did not have increased rates of pulmonary
exacerbations compared to those in the normal/healthy weight category.
Conclusion: As CF therapies continue to improve, an increasing number of
people with CF are exceeding the CDC’s normal weight range. Gaining
weight past the normal range does not appear to negatively impact
pulmonary health of people with CF. If this trend of increased weight
gain continues, it remains to be seen if it will eventually negatively
affect lung health.
Thermal decomposition and fire extinguishing mechanism of CF3I: a combined theoretical and experimental study
Authors: Yu Rourou , Hu Wenhao , Zhang Xiao , Wang Xingyu , Tan Zhaoyang
Published: August 2021

The urgent desire for Halon substitution propels the exploration of
potential alternatives, because of the severe damage of Halons to the
stratospheric ozone layer. In this paper, the thermal decomposition
mechanism, as well as fire-extinguishing mechanism and performance of
Trifluoroiodomethane (CF3I) were studied by density functional theory
(DFT) calculation and experimental measurements, to analyze the
practicability of this proposed Halon substitute. The thermal
decomposition products of CF3I can react with active OH· and H· radicals
to achieve the purpose of rapidly fire-extinguishing. Besides, through
DFT calculation and reaction kinetics analysis, the fire-extinguishing
radicals CF3· and I· are more easily generated during the interaction
between CF3I and flame, which indicates the chemical- extinguishing
mechanism and pronounced fire-extinguishing performance of CF3I. To
explore its actual fire-extinguishing effect, the fire-extinguishing
concentration (FEC) of CF3I was measured in cup burner. The FEC value of
this proposed Halon substitute is 3.42vol% for extinguishment of
methane-air flame, which is smaller than those of three HFCs and
HFO-1336mzz(Z) and is comparable to that of Halon 1301. These findings
suggest the promising applicability of CF3I in practical Halon
replacement and the necessity of further evaluation.
Second-Line Therapy for Type 2 Diabetes Management: The Treatment/Benefit Paradox of Cardiovascular and Kidney Comorbidities
Authors: McCoy Rozalina G. , Van Houten Holly K. , Karaca-Mandic Pinar , Ross Joseph S. , Montori Victor M. , Shah Nilay D.
Published: August 2021

OBJECTIVE

To examine whether glucagon-like peptide 1 receptor agonists (GLP-1RA) and sodium–glucose cotransporter 2 inhibitors (SGLT2i) are preferentially initiated among patients with cardiovascular disease, heart failure (HF), or nephropathy, where these drug classes have established benefit, compared with dipeptidyl peptidase 4 inhibitors (DPP-4i), for which corresponding benefits have not been demonstrated.

RESEARCH DESIGN AND METHODS

We retrospectively analyzed claims of adults with type 2 diabetes included in OptumLabs Data Warehouse, a deidentified database of commercially insured and Medicare Advantage beneficiaries, who first started GLP-1RA, SGLT2i, or DPP-4i therapy between 2016 and 2019. Using multinomial logistic regression, we examined the relative risk ratios (RRR) of starting GLP-1RA and SGLT2i compared with DPP-4i for those with a history of myocardial infarction (MI), cerebrovascular disease, HF, and nephropathy after adjusting for demographic and other clinical factors.

RESULTS

We identified 75,395 patients who started GLP-1RA, 58,234 who started SGLT2i, and 91,884 who started DPP-4i. Patients with prior MI, cerebrovascular disease, or nephropathy were less likely to start GLP-1RA rather than DPP-4i compared with patients without these conditions (RRR 0.83 [95% CI 0.78–0.88] for MI, RRR 0.77 [0.74–0.81] for cerebrovascular disease, and RRR 0.87 [0.84–0.91] for nephropathy). Patients with HF or nephropathy were less likely to start SGLT2i (RRR 0.83 [0.80–0.87] for HF and RRR 0.57 [0.55–0.60] for nephropathy). Both medication classes were less likely to be started by non-White and older patients.

CONCLUSIONS

Patients with cardiovascular disease, HF, and nephropathy, for whom evidence suggests a greater likelihood of benefiting from GLP-1RA and/or SGLT2i therapy, were less likely to start these drugs. Addressing this treatment/benefit paradox, which was most pronounced in non-White and older patients, may help reduce the morbidity associated with these conditions.
Implementación de un sistema natural para tratamiento de aguas residuales en zonas rurales. Estudio de caso para una institución educativa del municipio de Malambo – Colombia.

Published: August 2021

El continuo crecimiento de la población mundial, sumado a la creciente urbanización e intensificación de la producción industrial y agropecuaria, así como la sobreexplotación de ecosistemas acuáticos, terrestres y atmosféricos, ha traído consigo uno de los problemas más críticos que afronta la sociedad actual: la crisis de la disponibilidad de agua no contaminada. Dentro de los principales contaminantes que afectan y deterioran la calidad del agua se incluye la materia orgánica y los nutrientes quienes representan un riesgo ambiental, social y económico, que afecta a la salud humana, limita la producción de alimentos, reduce la funcionalidad de los ecosistemas y obstaculiza el crecimiento económico (UNESCO, 2015). Este hecho, afecta a la población más marginada, sobre todo a los que viven en zonas rurales puesto que son los que más usan el agua de los ríos o lagos para beber, para bañarse, lavar la ropa o cocinar. Un claro ejemplo de esta problemática se vive en el municipio de Malambo, en donde los cuerpos de agua de esta unidad territorial han presentado serios problemas de contaminación ambiental, lo cual ha repercutido negativamente en las condiciones de vida de la población que se ubica en los alrededores, no solo desde el punto de vista económico, con la disminución de la pesca, sino también desde el aspecto de la salud de sus habitantes. Para evaluar el uso de tecnologías basadas en sistemas naturales como una alternativa para la gestión sostenible del agua en comunidades rurales del municipio de Malambo, se implementó a escala de mesocosmo un sistema de humedal construido de flujo sub superficial horizontal HC-FSSH, para la remoción de materia orgánica y nutrientes en una institución educativa del municipio. La evaluación de esta unidad indico una eficiencia de remoción de materia orgánica y nutrientes, comprendida entre 70 y 95 % de la carga inicial. Esta variación puede estar, relacionada con la presencia de las plantas y el tiempo de retención hidráulico TRH. Los resultados de este estudio permiten concluir que los HC-FSSH pueden ser recomendados para remover contaminantes prioritarios como la materia orgánica y los nutrientes, de las aguas residuales contribuyendo con una gestión sostenible del recurso hídrico en comunidades rurales.
