Weeds impair the productive efficiency of agricultural crops, a species that has shown an increase in occurrence is the melon-de-são-caetano (Momordica charantia L.), and this causes losses due to competition for water, light, nutrients and space. Therefore, a treatment with an effective herbicide to control this species is of utmost importance for the reduction of the damage caused. Therefore, the present work aimed to evaluate different herbicide molecules associated with irrigation intervals in the control of são caetano melon (Mormodica charantia L.).

Prosopis cineraria (Ghaf) is considered as one of the highly valued trees in many arid and dry areas in the world. Historically, this tree has drag attention for its various uses therefore, in 2008, it was declared the national tree of the UAE not only for its sustainability through low water consumption and its ability to maintain desert ecosystems, but also for its many cultural uses. Ancient literature from Arabian Gulf and Indian desert illustrated the importance of the tree in treated various ailments like asthma, dysentery, leucoderma, leprosy, dyspepsia, earache, etc. The P.

The Brazilian brewery sector has significantly grown in the past few years due to recent developments from microbreweries and mid-scale craft beer manufacturers. Despite the slightly higher end-product cost, the diversity and improved quality are perceived as an acceptable trade-off by customers. The contemporary Brazilian scenario contrasts with the legacy mainstream beer producers that prevailed in market-share until late 90s with no competitors. In this article, we present a brief introduction of the beer history worldwide and its current state in Brazil.

O objetivo deste estudo foi ajustar equações matemáticas para estimar de forma não destrutiva a área foliar de mudas de Allagoptera arenaria a partir das dimensões lineares do limbo foliar. Para tanto, 205 folhas foram utilizadas sendo obtidas de cada folha as medidas do maior comprimento (C), maior largura (L) e área foliar observada (AFO). Determinou-se também o produto da multiplicação do comprimento com a largura (CL).

This work was conductedwith the objective of determining the discharge coefficient values and the characteristic curves (flow-pressure ratio) of two models of metallic silver and bronze domestic taps, with commercial diameters of ¾ and ½ inch. Each tap was subjected to 5 pre-established hydraulic loads (ranging from 2 to 30 m). Flow and discharge coefficient values differ between faucet models. The average flow rate of silver and bronze taps is 37.08 and 18.91 L min-1, respectively. The silver tap has a higher flow rate diameter inches (39.10 L min-1).

The aim of this study was to evaluate the microbiological and sensorial quality of guava jam functionalized by the addition of concentrated grape juice. Two formulations were prepared: guava jam enriched by the addition of concentrated grape juice in the proportion of 30% (w/w) (SF), with sucrose, and guava jam enriched by the addition of concentrated grape with no added sugar (DF), in which sucrose was replaced by a commercial blend of sweeteners.

Duchenne Muscular Dystrophy (DMD) is considered to be the most common muscular dystrophy. It is caused by changes in the DMD gene that is responsible for the production of the protein dystrophin. It predominantly affects the male sex, with an incidence of one in three thousand five hundred (1: 3,500) live births, the female sex is usually asymptomatic carrier. The first symptoms of DMD are characterized by balance deficits, frequent falls and difficulty lifting and jumping due to weakness in the muscles that initially affect the lower limbs.

This work evaluated the antiadhesive activity of two microbial exometabolites: indole and pyocyanin. The in vitro quantitative microtiter adherence assay was carried out with Pseudomonas aeruginosa exposed to concentrations of 0.5 and 1.0 mM of indole and Escherichia coli exposed to 0.2 mM of pyocyanin. The incubation took place for 48 hours at 30ºC. Afterwards, the violet crystal test was performed and optical density measurements (590 nm) were used to calculate the percentage of adhesion relative to the control tube, in which the cells were cultured in the absence of exometabolites.

The present investigation is aimed at assessing the current Ground Water Quality standard of Jammu City in terms of Physico-chemical parameters. In the selected study area the talab tillo is receiving considerable amount of man made products such as gasoline oil , road salts, and chemicals get into the ground water and witnessing an untreated waste from septic tanks and toxic chemicals from underground storage tanks and leaky landfills to contaminate the ground water.

The objective of this research was to compare the physical-chemical, spectroscopic and fatty acid profiles of Brazil nut oils from the 2018 and 2019 harvests. The methodological procedures followed the internationally accepted standards of the American Oil Chemist’s Society. The analysis of the physical-chemical properties showed oils with high quality for human consumption, within the quality standards defined by Brazilian legislation. In relation to the different harvests, during the analyzed period, they did not present differences maintaining their high quality as a function of time.
