Produtividade acumulada (PAC) das matrizes em rebanhos Nelore do norte e nordeste do Brasil

Abstract: The accumulated productivity (ACP) is an index that takes into account the total weight of calves weaned per cow (in kg), total time required for producing the calves and age at first calving. A study was conducted to estimate the components of genetic and residual variance and estimate the heritability of ACP index. Data set consisted of 2,816 observations of Nelore cows raised in different farms of the Brazilian North and Northeast. These farms participate in the Genetic Improvement Program of the Nelore Breed. The observed mean and respective standard deviation for ACP was 96.74 ± 46.70 kg of weaned calves/cow/year, with a coefficient of variation of 48.27%. This mean ACP, however, is lower than values estimated in other herds of the Nelore genetic program. Also, Standard Nelore cows showed higher ACP in comparison to cows of the Nelore Polled variety. Estimated heritability for ACP was 0.11 ± 0.06, suggesting that there is sufficient genetic variability that justify the use of ACP in genetic selection. However, results of such strategy depend, mainly, on efficient herd management.

Automatic lattice fabrication apparatus

Abstract: This invention relates to automatic lattice fabrication apparatus for automatically forming sections of lattice from strips of wood of a predetermined length and width. The apparatus includes an elongated horizontal conveyor that conveys lattice strips from a lay-up section through an automatic adhesive dispenser, under an automatic stapling bridge where the lattice is stapled, through rip saws that trim the sides of the lattice and, when desired, cut the lattice in half, and through an automatic cross-cut saw mechanism that periodically stops the conveyor, lowers a saw and cuts off a section of lattice when it reaches a predetermined length, and then lifts the saw out of the way and resumes conveyor movement.

Manejos da fertirrigação e doses de N e K no cultivo de pimentão em ambiente protegido

Abstract: Este trabalho foi desenvolvido com o objetivo de se avaliar os efeitos de manejos de fertirrigacao e niveis de nitrogenio e potassio sobre o crescimento e a producao de pimentao cultivado em ambiente protegido. Utilizou-se o delineamento em blocos casualizados com 18 tratamentos e quatro repeticoes. Os tratamentos resultaram da combinacao de tres manejos da fertirrigacao e com seis doses de nitrogenio e potassio. Foram realizadas seis colheitas e, nelas, avaliacoes quanto ao numero, massa media e producao de frutos alem de indicadores de crescimento (area foliar, altura e acumulo de fitomassa). Os resultados obtidos demonstram que o crescimento e o rendimento do pimentao dependem, alem das doses de N e K, do manejo de fertirrigacao adotado. O manejo da fertirrigacao a partir do monitoramento da concentracao de ions de N e K com auxilio dos extratores de solucao, ou da condutividade eletrica da solucao do solo e mais eficiente que o manejo tradicional. O monitoramento da solucao do solo deve ser realizado utilizando-se, como referencia, as concentracoes variando de 200 e 250% de N e K correspondentes a recomendacao para a cultura do pimentao em sistema hidroponico.

Symptomatic manifestations of the disease caused by coronavirus (COVID-19) in adults: systematic review

Abstract: Objective To identify symptoms of COVID-19 in adults in the scientific literature. Method Systematic review of studies published from December 1, 2019 to April 21, 2020 from the Scopus, Web of Science and PubMed databases, in order to answer the following research question: “What are the symptoms caused by COVID-19 in adults?” using the keywords “Symptoms”, “Clinical Manifestations”, “Coronavirus”, “COVID-19”. Results Of the total 105 references, 13 references that addressed the symptoms of COVID-19 were selected. Fever and normal or dry cough were symptoms present in all studies. Conclusion The symptoms identified in adult patients were fever, normal or dry cough, headache, pharyngalgia, dyspnea, diarrhea, myalgia, vomiting, sputum or expectoration, anxiety or chest pain, fatigue, nausea, anorexia, abdominal pain, rhinorrhea, runny nose or nasal congestion, dizziness, chills, systemic pain, mental confusion, hemoptysis, asthma, taste disorder, smell disorder, belching and tachycardia.
