Benefits of cyber-physical systems for maintenance in the industry 4.0

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).

Effects of different types of cuffs for training with restriction of blood flow: A systematic review

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.

Analysis of publications on occupational safety and health in waste management: A systematic Review

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.

Effect of goal difficulty on learning of the volleyball serve

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 maturity models in agile software development teams: Focus on human factors

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.

Desempenho da marcha nos diferentes ambientes em pacientes com paralisia cerebral níveis ii e iii

Introduction: Cerebral palsy is a predominantly sensorimotor disorder that involves disorders of muscle tone, posture, and voluntary movements, caused by non-progressive brain injuries. This health condition significantly interferes with the child's interaction in relevant contexts, which influences the acquisition and performance of basic motor milestones, as well as the daily routine activities. It is also known that the stimuli given to patients are extremely important for neuropsychomotor development, and they can act as facilitating or limiting functionality.

A new Segmented Plume Approach for Pollutant Dispersion Modelling

A segment approach is presented that allows to describe the temporal evolution of the dispersion of passive pollutants in non-stationary meteorological conditions. The methodology consists of a continuous series of source emissions integrated in time intervals whose result is a plume segment and has no numerical inversion, which refines earlier literature approaches. The dispersion of pollutants is subject to advection in horizontal direction and turbulent diffusion in all three directions, in an inhomogeneous and non-stationary atmospheric boundary layer.

Artificial intelligence for support of the bioethical decision-making of nurses related to end of life issues

Health professionals, especially nurses, are often compelled to make decisions in face of bioethical issues commonly related to intensive care environments. Due to their complexities and particularities, these issues end up generating great physical and emotional strain on the professional. Therefore, this study raised the hypothesis that artificial intelligence techniques could assist nurses in making bioethical decisions. For this, a group of four specialists in the field of nursing prepared and answered a questionnaire based on a hypothetical ICU scenario.
