Authors: Abo Nassar Nour Eldeen
Published: August 2021

The construction industry is one of the most significant industries that contribute greatly to achieving economic development. However, it is also considered one of the industries that is always exposed to a high risk of hazards in addition to being full of risky activities. Accidents that occurred in construction industries have caused many defects in project progress, for example, delays in completing the project, increasing project cost, reducing productivity, and creating negative impressions about the company. The major reason for the accidents is poor worker safety performance, with a host of contributing causes. For improving safety performance, the root causes of incidents that occur in construction as well as the factors influencing them must be studied. Health and safety issues are the main problem and concerns in the building industry. Though much development has been made in construction safety, the industry still lacks a lag behind most other industries in terms of safety. The aim of this paper is to provide a comprehensive review of the factors that could affect the safety performance of a construction site to reduce the frequency of accidents.

Published: August 2021

Buscou mostrar e explicar a história da alfabetização apresentando algumas das dificuldades enfrentadas durante o processo de alfabetização, que está dividido em três grandes períodos. O primeiro inclui a Antiguidade e a Idade Média onde predominava o método da soletração; o segundo iniciou-se por uma revolta contra o método da soletração e ficou marcado pela criação dos métodos sintéticos e analíticos e o terceiro período que, com a divulgação da Psicogênese da Língua Escrita, questionou a necessidade de associar os sinais gráficos da escrita aos sons da fala para se aprender a ler e a escrever. O foco principal de todo o trabalho é a concepção da Psicogênese da Língua Escrita, fundamentada pelas autoras Emilia Ferreiro e Ana Teberosky, que tiveram como referência a teoria de Jean Piaget. Faz-se uma reflexão sobre a relevância da concepção para entender todo o processo de aprendizagem de leitura e escrita e sua grande repercussão conceitual na alfabetização Brasileira. Foi utilizada a metodologia bibliográfica, com o objetivo principal de analisar o processo de aquisição da escrita alfabética e o papel do professor diante deste processo. Apresentam-se os aspectos comuns em todo percurso e processos individuais da base alfabética escrita, esclarecendo as hipóteses presentes durante esse processo, que vêm divididas em três grandes períodos. Conclui-se então que é de fundamental importância a disposição do professor para estudar, para construir sua competência profissional para que possa planejar e programar situações de aprendizagem.

Authors: Caproni Luana Marcondes Emergente , Madeira Leticia Alves , Santos Gérsika Bitencourt
Published: August 2021

Essa revisão sistemática tem como objetivo reunir conhecimentos de estudos já realizados, selecionando dados importantes que demonstram o impacto da insuficiência renal em regiões de baixa renda. Com base nas análises feitas, foi identificado que indivíduos afro-americanos predispõem de variantes genéticas que aumentam o risco para doença renal crônica. Além disso, a desnutrição das gestantes acarreta no nascimento de filhos com baixo peso, fato este que resulta no possível desenvolvimento de doença renal crônica.  Os artigos também revelam que a carência na atenção primária da saúde tem como consequência o aumento de enfermidades que são fatores de risco para a doença renal crônica, como diabetes e hipertensão. Por fim, os indivíduos que vivem em locais de baixo status socioeconômico têm grande desvantagem no acesso às terapias renais substitutivas, o que eleva de forma acentuada o índice de mortalidade nessas regiões.

An Investigation Into the Mathematics of Decryption Techniques in RSA Encryption, With an Implementation in Python
Authors: Flynn Sofia
Published: August 2021

This study explores the mathematics of two different techniques that can be used to access the decryption key in RSA encryption including semi-prime factorization and a logarithmic method. The study then presents a Python program, written by the author, that automates the calculations for either of the decryption techniques and also calculates the number of iterations required to determine the decryption key in either circumstance. Most importantly, the program utilizes only values of the RSA encryption algorithm that would be made publicly available in actual circumstances to calculate the decryption key so as to mimic real-life occurrences with as much integrity and accuracy as possible.
GPR40 and Postsynaptic NMDA Receptors: A Pair Against Epilepsy
Authors: Mullangi Vidya , Shah Nikita , Nam Hyunwook , Asch Alexa , Cox Lauren , Mendoza Clarisa
Published: August 2021

Epilepsy is a chronic neurological condition characterized by abnormal brain activity, unusual behavior, and loss of awareness. One of the most common features is the spontaneous recurrence of unprovoked seizures that mainly affect the hippocampus and cortical regions of the brain. Although the exact cause of epilepsy is still unknown, a mix of genetic, neurological, and environmental factors play a role. A novel study by Yang et al. explores the metabotropic receptor GPR40 which is suspected to be involved in the regulation of epileptic seizures, specifically through its modulatory role on NMDA receptors in the central nervous system. Their findings suggest that GPR40 induces NMDA receptor endocytosis via direct interaction with NR2A and NR2B subunits of postsynaptic NMDA receptors. Through this mechanism, NMDA-mediated postsynaptic currents are altered, resulting in reduced seizure-like activity. This review article discusses these novel findings which not only shed light on the potential molecular mechanisms of epilepsy but also push the scientific community closer to developing a treatment for this disorder.
Cancer Models to Defeat Therapy Resistance in Pancreatic Ductal Adenocarcinoma
Authors: He Britney
Published: August 2021

One of the largest hurdles to the efficacy of cancer therapeutics, and a main cause of relapse, is therapy resistance. In response, researchers have developed model systems to better understand therapy resistance. Cancer research employs several model systems that reflect the biology of actual human tumors: in vitro models (2D, 3D cell cultures), in vivo models (PDX, GEMMS, transgenic), proteomic models, and computational or mathematical models. One cancer that has been extensively modeled is pancreatic ductal adenocarcinoma (PDAC). PDAC is the third most common cause of annual cancer deaths in developed countries; as its incidence and mortality rates continue to increase, PDAC is projected to be the second leading cause of cancer deaths by 2030. Although chemotherapy is a pillar of clinical PDAC treatment, its outcome typically leads to multi-drug resistance, drastically restricting the curative effect of drugs for a variety of tumors. Elucidating the underlying mechanisms for resistance through different models is essential for the development of new strategies and therapies. This review provides insight into the range of in vitro and in vivo models of pancreatic cancer used in preclinical research. This paper provides an overview of platforms for cancer research with a focus on those devoted to resistance mechanisms in PDAC and to the primary therapeutic intervention for PDAC, gemcitabine (GEM).

Study Of The Stability Of Water-In-Oil Emulsion Intended for the Extraction of Heavy Metals Application: Copper Ions
Authors: Bouranene Saliha
Published: August 2021

This work aims to optimize the parameters that affect the stability of a W/O emulsion to exploit it in the extraction of heavy metals contained in the liquid effluents. The study of the emulsion stability shows that; an emulsification time of 10 minutes, a surfactant concentration of Span80 equal to 3% (w/w), an extractant concentration of Triethylamine N(CH2CH3)3 equal to 5% (w/w), an internal phase concentration of phosphoric acid (H3PO4) of 0.75M, a volume ratio of membrane phase to internal phase of 1, a volume ratio of external phase to the emulsion of 20 and a stirring speed of 180 rpm; lead to the formation of a very stable emulsion with a very low rupture rate of around 1.92% after one hour of contact time. The results of extraction of copper ions revealed that under the best operational conditions, the extraction yield was closed to 93.33% for 20% extractant content, a contact time of 12 minutes, and an initial concentration of copper ions of 400 ppm. The application of this new membrane matrix based on phosphoric acid used as inner phase, sorbitan monooleate as a surfactant, and Triethylamine as extractant has been proven effective for extracting copper ions in water.

O objetivo deste artigo é promover uma visão integrada do meio físico, caracterizando o Parque Estadual Serra da Boa Esperança (PESBE) por meio do mapeamento temático de variáveis geoambientais e das inter-relações existentes, relacionadas especialmente ao meio físico. A metodologia consiste na elaboração do mapeamento e na análise de variáveis que explicam o meio físico na Unidade de Conservação (UC), tais como hipsometria, declividade, índice de vegetação, densidade de drenagem, densidade de lineamentos estruturais e densidade de vias de circulação. Foi constatado que o PESBE, localizado no Sul/Sudoeste de Minas Gerais, abriga uma vasta rede de drenagem, apresenta relevo serrano influenciado pelos litotipos presentes na área e secundariamente pelas estruturas, sendo majoritariamente recoberto por uma vegetação pouco densa e marcado por trilhas oriundas da atividade de motociclismo Off Road. Sugere-se que sejam tomadas medidas para o controle desta atividade, pois ela não condiz com os objetivos de preservação da UC.

Introduction

To explore the relationship between the tertiary lymphoid structures (TLSs) and tumor-infiltrating lymphocytes (TILs), and their distribution characteristics as well as the prognostic value in gastric cancer (GC).

Material and methods

The TLSs and four subtypes of TILs were assessed by immunohistochemical (IHC) staining. The presence of MECA-79 positive high endothelial venules (HEVs) identified among the ectopic lymphocyte aggregation area in the GC tissue was defined as valid TLSs. The number of labeled TILs was observed in 5 fields of the most positive cells in the tumor center, invasive edge and within the TLSs, at a field of vision ×40.

Results

The TLS distribution was significantly higher in the tumor invasive edge than the tumor center (p < 0.001). Similarly, the infiltrating density of CD8+ T cells and GrB+ T cells was statistically significantly higher in the tumor infiltrating edge than the tumor center. The total number of TILs and FOXP3+ T cells showed a contrary distribution. There was a positive correlation of the density of TLSs and TILs with both the location and the immune phenotype. A higher frequency of TILs and TLSs is often associated with favorable clinicopathologic parameters. Higher numbers of peri-TLSs (p = 0.007), peri-CD8+ (p = 0.019) and peri-GrB+TILs (p = 0.032) were significantly correlated with the favorable overall survival. Multivariate analysis revealed that the densities of TILs (p = 0.019) and TLSs (p = 0.037) were independent prognostic predictor for GC patients.

Conclusions

We provide evidence that TLSs were positively associated with lymphocyte infiltration in GC. Thus, the formation of TLSs predicts advantageous immune system function and can be considered as a novel biomarker to stratify the overall survival risk of untreated GC patients.

Introduction

In-stent restenosis (ISR) is an unfavorable outcome that occurs in patients after coronary stenting. Using of drugs like statins as well as drug-eluting stents has only been partially effective in reducing the rate of ISR. Since low high-density lipoprotein cholesterol (HDL-C) concentration is a pivotal cardiovascular disease risk factor, this study aimed the evaluation of the compositional and functional alterations of HDL in individuals with ISR.

Material and methods

This case-control study comprised 21 ISR, 26 non-ISR, 16 angiography-negative, and 18 healthy subjects. Serum HDL2 (d: 1.063-1.125 g/mL) and HDL3 (d: 1.125-1.210 g/mL) subfractions were extracted from each subject using sequential ultracentrifugation. The capacity of HDL to efflux cellular cholesterol from lipid-loaded macrophages as well as to uptake free cholesterol (FC) from triglyceride-rich lipoproteins (TGRL) during lipolysis were assessed.

Results

No difference was found in the HDL2 and HDL3 content of free cholesterol and total protein among the groups. NISR group showed reduced triglyceride content in HDL2 and increased phospholipid content in HDL3 relative to healthy subjects. Strong positive correlations were found between the cholesterol efflux capacity (CEC) of HDL2 and its phospholipid content in the healthy (r=0.50), angiography-negative (r=0.55) and ISR (r=0.52) groups. The capacity of apolipoprotein B (apoB)-depleted serum to uptake free cholesterol was not different among the groups

Conclusions

Despite some compositional alterations, the capacity of HDL to efflux cholesterol from lipid-loaded macrophages as well as to uptake free cholesterol from TGRLs during lipolysis were not associated with ISR in this study

Cloud technology has exponentially seen a rise in its absorption for various applications. Cloud users with limited storage might transfer their information to remote systems. In return for monetary compensation, these servers provide access to their clients’ data. Cloud storage protocols verify the integrity of this data which is hosted on the cloud. Broadly there are two types of data – static and dynamic. While many efficient protocols are already present for static data, much research is being undertaken to build a secure cloud storage system for dynamic data. This paper analyzes these existing and proposed cloud storage protocols for both static and dynamic data. Important performance parameters are identified and a comparison is drawn between the chosen methods in order to draw a contrast between the efficiency of the techniques chosen.

In the present time, Permanent Magnet Synchronous Motors (PMSMs) are extensively used in many industrial applications due to its advantages over conventional synchronous motor. The PMSM is compact and efficient with high dynamic performance, thus having more advantages such as light weight, small size and bulky burden ability. When PMSMs are failed during the operation then large revenue losses occurs for industries. Hence, it is essential to diagnose these faults before occurring, for protection of any industrial plant. In the paper, firstly a comprehensive review of condition monitoring has been done for PMSM faults and their diagnostics techniques. From review, it is found that the stator inter-turn fault diagnosis has been the challenging task for many researchers. Hence, the work has been extended for fault analysis of stator inter-turn under transient conditions, which is effectively analyzed with the help of advanced signal processing technique.

Renewable energy is considered an infinite source of energy. Although they have unlimited potential towards making our environment self-sustainable, they are currently insufficiently exploited and unevenly distributed. The major hindrance to exploiting these renewable sources is economic issues. Some countries, that possess these sources are currently developing or are still in the under-developed scenario. Hence, these resources are not being exploited to their full potential. We are aware of the severe consequences of burning up fossil fuels and their adverse effect on our environment Rarely do we think of the consequences on the environment due to renewable energy sources. Although they have a very small impact on our environment, in the future it might lead to some devastating issues. Some of the renewable energy sources have a visual impact on the nature of our earth and also to some extent it can affect the ecosystem of a particular area. This paper intends to analyze the current types of renewable sources (solar, wind, geothermal and hydroelectric) and their impact on our planet.
