The adsorption isotherms of ciprofloxacin (CIP) by the spent coffee grounds (SCGs) was investigated. The adsorption isotherms were well described by the Langmuir model. This suggested that the strong interaction of CIP with the SCGs. Therefore, SCGs, as a green, environmental-friendly adsorbent, can be applied to the adsorption of contaminants in environment.
The developments achieved by electric machines in recent decades were more significant in terms of their resizing and in the ways in which they are activated than in the field of materials used for their manufacture. The electric machine project proposes the improvement of the technology of a three-phase synchronous machine through changes in the material and in the manufacturing process of the rotor and stator cores.

The COVID-19 disease was detected in Wuhan-China in December 2019; in March 2020, it was declared a pandemic. Due to the high transmissibility, there was a need to adapt protocols for the use of Personal Protective Equipment (PPE) to provide health care, substantially increasing its use. However, increased demand and production shortages culminated in rising costs. The aim of this study was to analyze the economic impact on the cost of acquiring PPE in the face of the COVID-19 pandemic. An integrative literature review was performed in PubMed, LILACS and CINAHL databases.
The present study intends to determine the personnel turnover rates of a small company operating in the textile industry, located in the interior of the state of São Paulo, from 2010 to 2019. Characterized as descriptive, with a case study approach, the data of admission and dismissal, among others, were collected through documentary research and interviews with partner directors. The results show an expressive turnover rate, with an average of 44.05% for the analyzed period. The years 2014 (77.78%), 2017 (63.64%) and 2019 (54.17%) were the ones with the highest values.
Among the pandemics that devastated humanity in the last 100 years, those caused by influenza viruses, belonging to the Orthomyxoviridae family, stand out. In December 2019, incity ofWuhan, China, a new coronavirus has been identifiedbelonging to the subfamily Coronaviridae. The etiological agent causing the new pandemic characterized as COVID-19 is the Sars-CoV-2 betacoronavirus, which infect animals and humans in a wide variety.This is a descriptive cross-sectional epidemiological study.
Aspects of populational structure of Epinephelusitajara were studied with specimens obtained as by-catch of fisheries of the species Tarpon Megalops atlanticus, in coastal and estuarine areas of Maranhão Gulf, Northeastern Brazil (02°05'38"S - 2°10'16"S / 43°34'06"W - 44°23'40"W). Samples were taken monthly between july/2016 and december/2016 from landings in the municipality of Raposa. A total of 14 specimens were analyzed by measuring the following variables: total length (cm) and body weight (Kg).
Leather producers in Ghana often do plain dyeing, they however, lack patterns that are attractive to enhance the surface appearance. As a result, when the leather is being used to make artefacts they apply stamping, carving, embossing, scorching, applique or printing just to register designs on themin order to enhance their aesthetic value, and these are only meant to be attracted to those who use the leather.It is for this reason that this research seeks to investigate into natural patterns as decorative motifs. The descriptive experimental research approach was used for the study.
