This research aimed to describe the knowledge of adolescents in elementary school about the menstrual period and analyze the existing sanitary facilities in public schools for menstrual hygiene. This is a descriptive, cross-sectional study with a quantitative approach. The participants were 39 students between 11 and 17 years old who have had their first menstruation.

Blister blight pathogen is not only affect the crop productivity,but also impart quality deterioration of processed teas. Among the biochemical constituents, polyphenols and catechins declined considerably due to blister blight infection. This study deals with impact of blister blight infection in relation to relative distribution of catechins of popular, quality tea clones. Results obtained in the present study revealed that irrespective of the cultivars, processed green tea obtained from healthy crop shoots contained significantly higher amount of total polyphenols and catechins.

The elements that make up some systems are competing with each other for resources. Following the path of ending this struggle, evolution strengthens the reliability of the existence of these systems. This is how the Metazoa and Metaphyta evolved. Therefore, they thrive on the Earth. The development of human societies is a special case of the evolution of systems that have improved the reliability of their existence by stopping the struggle between elements of which they consist. The engine of this struggle is atavistic instinct of selfishness.

Objective: To highlight the agglomerations where the risk of transmission of onchocerciasis is highest in the region of Aboisso, with a view to eliminating this endemic in Côte d'Ivoire. Methods: Entomological surveys were carried out in the Aboisso region in the south-east of Côte d'Ivoire, in the forest zone, during the last semester of 2013 (from 2 July to 27 December). These surveys are part of a better knowledge of the status of onchocerciasis transmission in Côte d'Ivoire.

Os problemas ambientais originados pelo uso de adubosquímicos associados ao seu elevado preço fez com que na presente pesquisa fossem avaliados dois adubos orgânicos de origem galinácea como forma a minimizar os custos de produção da couve. Desta feita, a pesquisa objectivou avaliar efeitos dos adubos orgânicos no desempenho da cultura de couve tronchuda. Para tal, foi desenvolvida uma pesquisa experimental obedecendo ao desenho experimental completamente casualizado com três repetições e três tratamentos (testemunha, cama de frango e esterco de galinha sem cama).

The increase in the demand for fish highlights the aquaculture potential of the Brazilian Amazon. The high cost of electric energy, lack of technical staff and inexistence of continuous control of water quality parameters are some of the factors that hinder the growth of this activity. We evaluated two opportunities for automation and optimization in commercial tambaqui farms in ponds in Amazonasstate, Brazil. The first is the manual control and recording of physical-chemical properties of the water, and the second is the high consumption of electricity by the aerators.

Este estudo objetivou analisar as folhas de araticum do mato Duguetia furfuracea (A.St.-Hil.) Saff.) encontrados na zona de transição amazônica maranhense para determinação de seus componentes químicos, metabólitos secundários, compostos bioativos e sua atividade biológica como ação antimicrobiana. As folhas de araticum foram preparadas para análise a partir de secagem e trituração, e realizadas as análise químicas e biológicas seguindo metodologias descritas na literatura.

In 2020, the world was faced with the pandemic of COVID-19 and the social distancing to contain the transmission of the new coronavirus, SARS-Cov2. In education, there was a transition from face-to-face to virtuality, indicating possibilities, dilemmas, and even illness among those who engage in teaching practice. Mobile devices connected to the internet have been the bridge between the teacher and the student, between the family and the community; however, they are far from being savior resources in Education.
