Reference values for cardiac chamber quantification are essential for clinical decision-making. Brazil is a continental country with marked racial diversity and substantial regional socioeconomic and anthropometric variability, which may not be adequately represented in international echocardiographic standards. To establish reference echocardiographic measurements for healthy Brazilian adults and to investigate geographic and sex-related differences across Brazil's major regions. In this prospective, multicenter study, transthoracic echocardiograms were performed in 496 healthy volunteers (mean age 41 ± 15 years; 55% women) from five Brazilian regions. Left ventricular (LV) and left atrial (LA) dimensions, volumes, mass, ejection fraction, and global longitudinal strain (GLS) were analyzed in accordance with current guidelines. Comparisons were conducted by sex (Student's t test or Mann-Whitney U test) and by region (analysis of variance). Cardiac chamber dimensions and LV mass were greater in men, even after indexing for body surface area. LA volumes were also higher in men, although these differences were attenuated after indexing. Absolute LVGLS and right ventricle (RV) GLS (RVGLS) values were higher in women, whereas LA strain reservoir (LASr) was similar between sexes. Regionally, the Center-West exhibited significantly smaller LV volumes, a difference primarily driven by women, along with lower LVGLS and RVGLS (p < 0.001). In contrast, LA volumes were smaller in the Northeast region. No significant associations were observed between self-reported race and echocardiographic parameters, except for RVGLS and LASr, which were lower in White participants. This study establishes echocardiographic reference values in a nationally representative Brazilian cohort, confirms expected sex-related differences, and identifies previously unrecognized regional variations in cardiac chamber dimensions. These findings underscore the need for population-specific standards to ensure accurate cardiac quantification.

Abstract: The objective of this study was to compare the selection of plants bred by different pedigree methods using selection among, among and within and only within families. The haploid induction rate of 14 S0:1 and seven S2:3 families, all crossed with the single-cross hybrid GNZ9501, was evaluated. An experimental area of ​​the Department of Biology of the Federal University of Lavras (UFLA), in Lavras, Minas Gerais, in the growing seasons 2012/2013 and 2014/2015, was used for the experiments. In each growing season, one experiment per was carried out, arranged in a complete randomized design, with one and two replications, respectively. Haploid induction was most effective in the families 2 and 6 in both growing seasons. Selection among and within families resulted in higher genetic gains for haploid induction. The results indicated a high genetic variability for haploid induction rate in plants within families.

Research at PT Summarecon Agung Tbk and PT Pakuwon Jati Tbk, located in Jakarta, aims to assess the financial performance of PT Summarecon Agung Tbk and PT Pakuwon Jati Tbk 2015-2017. The analytical method uses in this research is Du Pont System and Economic Value Added (EVA). Du Pont System is an analysis system intended to show relation between return on investment, net profit margin, and total asset turnover. Economic Value Added (EVA) is an additional value to shareholders by management in a certain period. The result of the calculation of the financial performance of PT Summarecon Agung Tbk year period 2015-2017 with the Du Pont System shows a positive value and tend to increase per year. And for the analysis method of Economic Value Added shows value fluctuation also decrease per year. As for the analysis using the EVA method, the fluctuating value also decreases per year. The results of the calculation of the performance of PT Pakuwon Jati Tbk period in 2015-2017 with Du Pont System showed a positive value and experienced an increase and decrease every year. As for the analysis using the EVA method, the value of fluctuations also decrease and increase every year. In this case, the company needs to improve the efficiency of the company, both PT Summarecon Agung Tbk and PT Pakuwon Jati in utilizing capital and managing assets owned by the company

Rice, a staple food for more than one half of the world’s population, is one of the most cold-sensitive cereals. Breeding programs aimed at increasing rice production are expected to reduce cold-imposed grain losses. Several reports have demonstrated that cold induce differential effects on the fatty acids profile of membranes in chilling-sensitive and chilling-tolerant plants. In this work, we evaluated changes in fatty acid (FA) composition as a potential screening tool to evaluate chilling sensitivity of rice accessions. Cold exposure led to the preferential accumulation of the polyunsaturated linolenic and linoleic FAs and reduction of palmitic and stearic FAs, besides showing increased lignoceric acid content in roots of the variety. Similarly, roots of cold-exposed line Quila 66304 also presented preferential accumulation of linolenic and linoleic FAs and reduction of palmitic and stearic FAs. Cold exposure also led to enhanced levels of palmitic acid in shoots of Amaroo and, in a smaller extent, in shoots of Quila 66304. Linolenic acid was reduced in the shoots of both Amaroo and Quila 66304, while oleic acid content was reduced in shoots of Amaroo and slightly increased in shoots of Quila 66304. Double-bond index analysis indicated that 18 carbons FAs DBI for roots might be a good screening tool for cold response in rice. Results in this report demonstrate that cold-induced changes in FA profile represent a useful screening tool for early identification of differences in cold acclimation potential among rice accessions.

The traditional operational and hazard control paradigm of an electrical installation has several issues pertaining to the diversity of equipment. A large maintenance inventory is a reason for concern for any manager, but the arc-flash hazard is a particularly new phenomenon, and the effects of equipment diversity on this phenomenon are even newer. The class of arc hazard can be simply increased by changing the fuse link or circuit breaker manufacturer. Management pressure to operate as well as nonstandard practices and installations are also partly responsible. The aim of this article is to take a typical situation in an industrial plant and to statistically simulate, by means of a dedicated software program, the fuse arc-flash interruption performance of various manufacturers. The purpose of this article is to obtain a more objective indication of the influence of different fuse link manufacturers on arc-flash incident energy. © 1975-2012 IEEE.

Among the predaceous mites, those of the Phytoseiidae family are the most important and studied. The phytophagous mites Brevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae) and Oligonychus ilicis (McGregor, 1917) (Tetranychidae), on coffee trees ( Coffea spp.), are frequently found in combination with the predaceous mites Iphiseiodes zuluagai Denmark & Muma, 1972, Amblyseius herbicolus (Chant, 1959) and Euseius citrifolius Denmark & Muma, 1970, among others. The purpose of this research was to study the effects of the insecticide rynaxypyr (chlorantraniliprole 200 SC) on these three species of Phytoseiidae, relevant to coffee and citrus, following standard laboratory procedures. Mated female mites were exposed to fresh-dried residues on a glass surface, with 7 treatments, 5 mites per glass plate and 6 replicates, in a completely randomized experimental design. Each test lasted 8 days, with a daily count of the surviving females and of eggs laid. Rynaxypyr, in all tested concentrations (15, 30, 50, 100 and 500 mg a.i./liter of water), was selective for the studied species, A. herbicolus , I. zuluagai , and E. citrifolius . Overall the treatments resulted in low mortality rates and negligible impact on the reproduction. Therefore, based on IOBC standards, rynaxypyr can be classified as not harmful (Class 1), comparable to the agrochemical hexythiazox equivalent to a harmless standard of selectivity in the laboratory. Rynaxypyr is therefore a complement to programs of integrated pest management, to preserve the populations of predatory mites in crops of coffee and citrus, among others, in Brazil.
