Показана возможность получения пористого теплоизоляционного материала в виде гранул из песчаниковых вскрышных пород угледобычи, как альтернативное алюмосиликатное сырье техногенной основы. Выявлено, что на основе шихты, состоящий из 75% песчаника, 20% кальцинированной соды и 5% известняка получены гранулы с объемной насыпной массой 310–480 кг/м3 и прочностью при сжатии 2,1–3,2 МПа. Установлено, что на спекание, расплавление и вспенивание массы влияет дисперсность измельченного материала, где с уменьшением размера частиц повышается химическая активность компонентов.
The possibility of obtaining a porous thermal insulation material in the form of granules from sandstone overburden rocks of coal mining as an alternative aluminosilicate raw material of technogenic basis is shownin the article. It was revealed that on the basis of a charge consisting of 75% sandstone, 20% soda ash and 5% limestone, granules with a volumetric bulk mass of 310–480 kg/m3 and a compressive strength of 2.1–3.2 MPa were obtained. It is established that the sintering, melting and foaming of the mass is affected by the dispersion of the crushed material, where the chemical activity of the components increases with a decrease in the particle size.

Published: April 2023

This research paper presented the potential of Corchuros olitorius L. as a natural coagulant in the removal of turbidity, total suspended solids, and biochemical oxygen demand from the domestic wastewater of the University of Science and Technology of Southern Philippines. Optimization of the natural coagulant and synthetic coagulant was employed prior to the treatment design. The jar test method was used in the optimization and lab analysis including the gravimetric method, dilution technique, and digital measurements. The optimization results of Corchuros olitorius L. using the jar test method revealed better removal at a lower dosage of 50 mg/L and a higher settling time of 90 minutes. The characterization using FTIR analysis also suggests a functional group that influences coagulation activity. Using the optimum dose and optimum settling time, results with the different treatment designs showed the highest removal at pH 7 showed % BOD removal of 89.78% (A75C25); 85.98% (A25C75); 88.76% (A50C50). TSS removal measured values of 88.50% (A75C25), 85.56% (A25C75), and 87.16% (A50C50), while turbidity removal of 83.47% (A75C25), 80.27% (A25C75), and 80.27% (A50C50). Statistically, measured values differ between treatment designs. It is suggested to investigate removal efficiency in more varied pH conditions, different settling times, stirring speed, and other variables for future studies.

Competition in the business world is getting tougher from year to year both within a country and abroad. There are a large number of companies competing with one another, especially entering the free market share in Asia, namely the Asean Economic Community (AEC). In the current development of modern economy, Indonesia is making efforts to increase its economic growth. For this, developments in any fields are made. Among others is the service industry such as accommodation, travel, and transportation services. Considering that Indonesia is a country comprised of many islands with a variety of natural beauty, it has the very potential for tourist resort attraction. This kind of thing leads to the growth of the Travel, tourism and hotel industry to support development of tourism. With such rapid service industry development, supported by promising business opportunities, investors for such sector are encouraged. The right way to reduce risk for investors interested is to develop a system for estimating the stock prices. Therefore, in this study, the high and low stock price estimation method applied for travel companies adopted developed Kalman Filter, a comparison of two Kalman Filter development methods, namely Extended Kalman Filter (EKF) and Fuzzy Kalman Filter (FKF) as a chart for investors to take into consideration in their investment decision making. The simulation results showed that the EKF method had higher accuracy than the FKF method with an error by the EKF of 3.5% and that by the FKF of 8.9%.
Onboarding OpenAthens
Authors: Leffler David 
Published: April 2023

Liberty University is a private, Christian university in Lynchburg, Virginia. OpenAthens is a company that provides off-campus authentication for an organization’s electronic resources by redirecting URLs through a secure network. In 2022, Liberty University took action to begin transitioning from EZproxy authentication to OpenAthens authentication. There are three primary reasons why Liberty University chose to authenticate its electronic resources through OpenAthens:

OpenAthens provides greater security for accessing electronic resources by providing federated access for specific subscriptions.
OpenAthens requires less internal support to maintain access to electronic resources, such as the lack of requirement to maintain stanza updates, than other authentication products.
OpenAthens provides more granular reporting capabilities for usage data.

Therefore, organizations that plan to switch to OpenAthens authentication should consider their testing methods, plan for liaising with OpenAthens, and gain knowledge of OpenAthens terminology and different electronic environments before implementation to ensure a smooth onboarding experience.

Published: April 2023

In recent years there was great growth in forensic investigations in Brazil. Forensic biology has become an area of great impact in civil and criminal investigation which encompasses several fields, among them, laboratory analysis of livestock. This article aims to present concepts, demands and ways to develop activities of a quality management system in forensic veterinary work. Forensics can be used to help in the civil and/or criminal spheres, and in studies and research in the areas of animal, public, environmental and individual health (one health). In investigations, evidence is generally present and may be physical, chemical or microbiological in nature. The collection of evidence must be based on biosecurity standards and respect the chain of custody, which refers to the capacity of guaranteeing the identity and integrity of residues of any nature. It comprises tracing and allows for its chronological order to be documented and maintained. The demand for forensic veterinary work can be implemented in public research and teaching institutions or in private services, all of which have trained professionals and specialized laboratories that can perform tests and counter tests for technical-scientific expertise. The quality of a product or service is a fundamental factor for its insertion in the market. Forensic veterinary work can develop technical-scientific activities to meet the demands in facilitating justice through research of infectious agents of diseases in animals, toxic substances and contaminants, or the occurrence of crimes involving animals, contamination of environmental fauna, and fraud in foods of animal origin for human or animal consumption. The Quality Management System (QMS), including Good Laboratory Practices (GLP) and ISO 17025, enables forensic veterinary laboratories to adopt analyses using technical-scientific procedures with quality, reliability, punctuality and biosecurity, which are important in legal proceedings.

Clinical Research Progress of Different Acupuncture and Moxibustion Therapy for Perimenstrual Insomnia
Authors: Si Weichen 
Published: April 2023

Perimenopausal insomnia often shows the lack of quality or quantity of sleep, such as hard to sleep, wake up earlier, easier to wake up, and often accompanied by irritability, dizziness, palpitation, the symptom such as sweat out, hot flashes, night sweats, or mood problems such as depression, anxiety. The incidence of it increased year by year, the symptoms affects the work and daily life of modern women severely. Modern medicine believes the decline in estrogen levels is the cause, so hormone replacement therapy (HRT) is often used in clinic. But its side effects and drug dependence are much criticized. Traditional Chinese Medicine (TCM) believes that the deficiency of kidney is the root cause, leading to the imbalance of Yin and Yang. Acupuncture, as an effective therapy without side effects and obvious dependence, is now attracting more and more attention. This review mainly sums up by the selecting of acupoints, the location and the depth of the acupuncture therapy and other therapies recorded in published reports of treating insomnia in perimenopause, hoping it will be helpful to clinical treatment.

Boas práticas para as empresas se adaptarem ao envelhecimento da força de trabalho
Authors: Carmo Jorge Luiz do 
Published: April 2023

Estudos demográficos mostram que ano após ano a expectativa de vida vem aumentando e a população mundial está envelhecendo. Globalmente, a expectativa de vida ao nascer cresceu de 70 anos em 2010 para 73 anos em 2020 (STATISTA, 2023a). Uma expectativa de vida mais longa significa mais pessoas trabalhando por mais tempo. De acordo com a Organização para a Cooperação e Desenvolvimento Econômico - OCDE (2019), hoje em dia as pessoas vivem muito e com boa saúde, como nunca antes na história. A Figura 1 mostra o crescimento da força de trabalho com idade acima de 55 anos, entre 2012 e 2019, nas maiores economias do mundo e também no Brasil. Em 2019 a China contava com 17% dos trabalhadores com mais de 55 anos, os Estados Unidos 23%, Japão 30%, Alemanha 24%, Reino Unido 20% e Brasil 13% (STATISTA, 2023b). Os trabalhadores mais velhos estão cada vez mais saudáveis e dispostos a adiar a aposentadoria. A idade de aposentadoria desejável, que no passado era de 60 anos (HURSH et al., 2006), aumentou junto com o aumento da expectativa de vida. O aumento da participação dos idosos no mercado de trabalho leva as empresas a tentarem compreendê-los melhor, considerando suas características, comportamentos e desejos de carreira, com o objetivo de aumentar o sucesso profissional, fazê-los permanecer mais tempo na empresa e gerenciar o envelhecimento (KIM e KIM, 2022). Diversos fatores pessoais influenciam a tomada de decisão de quem está prestes a se aposentar, tornando a aposentadoria mais ou menos atrativa: saúde; situação financeira; atitudes em relação ao trabalho; aposentadoria; lazer; e fatores sociais e familiares (YEATTS et al., 2000).

Introduction: Oxford Nanopore Technologies (ONT) is a third generation sequencing approach that allows the analysis of individual, full-length nucleic acids. ONT records the alterations of an ionic current flowing across a nano-scaled pore while a DNA or RNA strand is threading through the pore. Basecalling methods are then leveraged to translate the recorded signal back to the nucleic acid sequence. However, basecall generally introduces errors that hinder the process of barcode demultiplexing, a pivotal task in single-cell RNA sequencing that allows for separating the sequenced transcripts on the basis of their cell of origin.Methods: To solve this issue, we present a novel framework, called UNPLEX, designed to tackle the barcode demultiplexing problem by operating directly on the recorded signals. UNPLEX combines two unsupervised machine learning methods: autoencoders and self-organizing maps (SOM). The autoencoders extract compact, latent representations of the recorded signals that are then clustered by the SOM.Results and Discussion: Our results, obtained on two datasets composed of in silico generated ONT-like signals, show that UNPLEX represents a promising starting point for the development of effective tools to cluster the signals corresponding to the same cell.

ObjectivesThe rat model of heart failure (HF) induced by doxorubicin (DOX), a broad spectrum and highly effective chemotherapeutic anthracycline with high-affinity to myocardial tissue that causes severe dose-dependent irreversible cardiotoxicity has been widely recognized and applied in HF pathogenesis and drug therapy studies. The gut microbiota (GM) has attracted significant attention due to its potential role in HF, and research in this area may provide beneficial therapeutic strategies for HF. Considering the differences in the route, mode, and total cumulative dose of DOX administration used to establish HF models, the optimal scheme for studying the correlation between GM and HF pathogenesis remains to be determined. Therefore, focusing on establishing the optimal scheme, we evaluated the correlation between GM composition/function and DOX-induced cardiotoxicity (DIC).MethodsThree schemes were investigated: DOX (at total cumulative doses of 12, 15 or 18 mg/kg using a fixed or alternating dose via a tail vein or intraperitoneal injection) was administered to Sprague Dawley (SD) for six consecutive weeks. The M-mode echocardiograms performed cardiac function evaluation. Pathological changes in the intestine were observed by H&amp;E staining and in the heart by Masson staining. The serum levels of N-terminal pre-B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) were measured by ELISA. The GM was analysed by 16S rRNA gene sequencing.Key findingsStrikingly, based on the severity of cardiac dysfunction, there were marked differences in the abundance and grouping of GM under different schemes. The HF model established by tail vein injection of DOX (18 mg/kg, alternating doses) was more stable; moreover, the degree of myocardial injury and microbial composition were more consistent with the clinical manifestations of HF.ConclusionsThe model of HF established by tail vein injection of doxorubicin, administered at 4mg/kg body weight (2mL/kg) at weeks 1, 3 and 5, and at 2mg/kg body weight (1mL/kg) at weeks 2, 4 and 6, with a cumulative total dose of 18mg/kg, is a better protocol to study the correlation between HF and GM.
