The need to survive in a competitive market forces companies to serve their customers with higher agility at even lower prices. Industry 4.0 technologies enable faster responses and lower costs in various operational processes, including the maintenance area. Maintenance has a significant impact on companies’ operational costs, and a program that contributes to the reduction of these costs is the Condition Based Maintenance (CBM).

Sistema de Governo da República Democrática de Timor-Leste, uma explicação dos problemas do sistema de Governo, uma vez que entrou em vigor a 20 de Maio de 2002, no entanto, na administração do Estado o governo tem vivido vários problemas constitucionais por resolver, o que levou a vários pontos de vista que Os países da RDTL usam uma variedade de sistemas de governo, mas é claro que Timor-Leste na prática usa um sistema semi-presidencialista de governo por normas constitucionais que é um sistema parlamentar.

Training with blood flow restriction shows positive results when associated with low training loads and similar when compared to high loads. There is still a gap in the literature regarding the influence of cuff sizes used in training, smaller cuffs require lower blood pressure levels to restrict blood flow in relation to larger cuffs, such a divergence can directly impact strength gains and hypertrophy.

Male infertility is a serious problem in the developing world. Spermatogenesis is highly sensitive phenomenon due to involvement of environmental and genetic factors. The present study has been designed with the aim to evaluate the frequency of MTHFR C677T gene polymorphism, DNA copy number variations, hormone profile changes, and karyotypic alterations to evaluate the ‘risk factor’ in male infertility. Blood samples (n=72) were collected from clinically diagnosed cases of non obstructive azoospermia (NOA) and sever oligozoospermic patients with respective control.

Population, urbanization and economic growth have caused waste generation rates to increase exponentially in recent decades. The inadequate disposal of waste as well as the disregard for waste management policies can not only cause damage to society and the environment, but also to workers who deal with different types of waste. The present work aims to identify the main scientific studies that address waste management linked to occupational safety and health and its main characteristics in order to understand which types of waste are most studied.

Several investigations have shown that Lactobacillus acidophilus has antioxidant systems, both in its whole cell and in extract of cell lysate. Thus, this study aimed at evaluating the efficiency of lysing cell to obtain extract of cell lysate, its antioxidant activityas well as intact cells, obtained from Lactobacillus acidophilus NCFM® cultures. Cell lysis was carried out using sonication and centrifugation processes, whose efficiency was measured by plating in depth after obtaining the extract process from cell lysate.

Covid-19, formerly known as pneumonia or 2019-nCoV disease, emerged as a global public health crisis. Severe acute respiratory syndrome (SARS) has spawned an increasing number of coronavirus-associated illnesses that have spread from animals to people. As a result of the rising number of sick people, several people started using drugs that presented at least a small effect against the symptoms of the disease. Among them, there is Ivermectin: an antiparasitic that obtained favourable results in its first in vitro experiments to combat the new Coronavirus.

The objective of this study was to evaluate the effect of the goal difficulty level in the learning of the volleyball serve, in both precision and the movement pattern. Ten adolescents (13 to 15 years old) inexperienced participated in this study. The dependents variables were accuracy to target and movement pattern of serve. The experiment was composed of three phases:pretest, acquisition phase, and retention test. The results demonstrated higher effectiveness of difficult goal for improve accuracy to target as well as in the movement pattern in comparison with easy goal.

The use of software products is growing, leading to an increase in quality demand. With that, standards were created to implement maturity models inside organizations, including CMMI and MPS-BR. Objective: To investigate the use of maturity models for the development of human aspects in agile teams. Method: A survey was carried out, and the results were analyzed based on the frequency of responses and qualitative analysis. Results: The maturity models focused on people management (P-CMM and MPS-RH) are still little known.
