O experimento teve a finalidade de comparar o desempenho e uniformidade de frangos de corte separados por sexo e criados em diferentes densidades populacionais. Para tanto foram utilizados 1800 pintos de 01 dia da linhagem Ross, distribuídos em 36 parcelas experimentais (Boxes), de acordo com um delineamento experimental tipo blocos ao acaso, obedecendo um modelo fatorial 3x2 com 3 sexos (Machos, Fêmeas e Misto) e duas densidades populacionais (10 e 15 aves/m²), com 6 repetições por tratamento, sendo ...

Objectives To investigate if compared with glycopeptides, antimicrobial therapy (AMT) with linezolid (LZD) improves the outcome in methicillin-resistant Staphylococcus aureus (MRSA) experimental pneumonia in mechanically ventilated piglets. Methods The MRSA minimal inhibitory concentration (MIC) was 0.5 for vancomycin (VAN), 0.25 for teicoplanin (TEI), and 2.0 μg/mL for LZD was inoculated in Largewhite-Landrace piglets divided into five groups. One group (n = 6) did not receive mechanical ventilation (MV) ...

Forest ecosystems strongly contribute to the mitigation of climate change impacts through the carbon stored in forests and through harvested wood products, such as sawed wood and furniture, which are obtained from many types of timber assortments. Timber assortments are defined as log sections of specific dimensions (log length and maximum/minimum end diameters), gathered from felled trunks, that have both specific commercial timber utilisation and economic value. However, it is challenging to discriminate ...

In COPD patients, hyperinflation impairs cardiac function. We examined whether lung deflation improves oxygen pulse, a surrogate marker of stroke volume.In 129 NETT patients with cardiopulmonary exercise testing (CPET) and arterial blood gases (ABG substudy), hyperinflation was assessed with residual volume to total lung capacity ratio (RV/TLC), and cardiac function with oxygen pulse (O(2) pulse=VO(2)/HR) at baseline and 6 months. Medical and surgical patients were divided into "deflators" and "non-deflators" ...

The concept and application of nature-based solutions (NBS) have been rapidly progressing in Europe and Latin America, reflecting a transition in the way that urban governance is perceived. There is a large call for the collaborative, polycentric, and interdisciplinary governance of NBS. However, research on options for operationalising these governance processes in different contexts is still insufficient. This study explores and analyses the operationalisation of NBS adaptive governance in Europe ...

This paper details the development of a single-shot diagnostic technique for the 4D average and core phase space densities of low-charge, high-brightness electron beams, based on the analysis of shadow point-projection images of metal grids. This technique is similar to the standard pepper pot method, although it allows much greater transmission of the beam and therefore is more suitable for low-charge electron beams. Transverse coupling terms are included in the analysis, allowing the complete ...

Abstract The authors compare the results of the surgical treatment of stress urinary incontinence (SUI) by the Marshall‐Marchetti‐Krantz technique with those obtained with endoscopic suspension of the bladder neck. In Group I, 30 patients with SUI were operated on by the Marshall‐Marchetti‐Krantz procedure with a 84% success rate. In Group II, 40 patients with SUI were operated on by the endoscopic suspension of the bladder neck (Stamey procedure) with 95% of cure. The results described in this second ...

The Nicaraguan revolution captured world attention as the Sandinista guerrillas developed a political strategy which incorporated the business classes into the struggle against Somoza and promised a revolution based on the principles of political pluralism, a mixed economy, and international nonalignment.Although the political strategy of the Sandinistas for the overthrow of the dictatorship did not differ drastically from that of Cuban revolutionaries [see Harnecker 1987], they have been able, even ...

A intensidade e a complexidade envolvidas no transplante de medula óssea (TMO), em seus vários níveis, produz profundos efeitos psicológicos no paciente, na família e na equipe profissional. Ignorar esta realidade e reduzir os problemas do TMO a seus aspectos puramente técnicos pode trazer consequências catastróficas para o paciente e seus familiares e ameaçar a sobrevivência da equipe. Neste trabalho, são discutidos três aspectos muito importantes de saúde mental no TMO, enfatizando a prática desenvolvida ...

Publisher Summary Cobalt-based catalysts have been widely used in the CO + H 2 reaction for hydrocarbons production; they are among several others to produce hydrocarbons from CO hydrogenation because of their ability to hydrogenate dissociated carbon species and promote chain growth. Cobalt is a typical metal that may adsorb CO molecules dissociatively forming carbon atoms at the surface, which may be hydrogenated, and it is an appropriate catalyst for the formation of long-chain hydrocarbons. However, ...

Hydroxyapatite (HA) ceramic in a porous configuration is suggested as a drug release system. A new technique for the production of this material, based on the foaming of suspensions and in situ polymerization (gelcasting method), resulted in a material whose characteristics are likely to make it useful as an implantable drug delivery system. Three batches of HA ceramic with different porosities were characterized by X-ray diffraction and scanning electron microscopy (SEM). Pore size and shape as well ...

Farmers are increasing the use of fertilizers in chestnut, the only cash crop produced in the mountainous areas of northeastern Portugal. This calls for more studies to guide them towards a more ecological intensification. The effects of three controlled-release fertilizers, two that release nutrients over three months (BoskGrow 20:05:20_3m, Exactyon 18:05:13_3m) and one over six months (Exactyon 18:05:12_6m), and an organic amendment authorized for organic farming (Humix 12:03:05) were compared with ...

Accurate structural information about forests, including canopy heights and diameters, is crucial for quantifying tree volume, biomass, and carbon stocks, enabling effective forest ecosystem management, particularly in response to changing environmental conditions. Since late 2018, NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission has monitored global canopy structure using a satellite Light Detection and Ranging (LiDAR) instrument. While GEDI has collected billions of LiDAR shots across ...

Accurate measurement of forest growing stock is a prerequisite for implementing climate-smart forestry strategies. This study deals with the use of airborne laser scanning data to assess carbon stock at the tree level. It aims to demonstrate that the combined use of two unsupervised techniques will improve the accuracy of estimation supporting sustainable forest management. Based on the heterogeneity of tree height and point cloud density, we classified 31 forest stands into four complexity categories. ...

Timber assortments are some of the most important goods provided by forests worldwide. To quantify the amount and type of timber assortment is strongly important for socio-economic purposes, but also for accurate assessment of the carbon stored in the forest ecosystems, regardless of their main function. Terrestrial laser scanning (TLS) became a promising tool for timber assortment assessment compared to the traditional surveys, allowing reconstructing the tree architecture directly and rapidly. ...

Imaging diagnosis of pancreatic solid-pseudopapillary neoplasms (SPNs) is difficult. Preoperative diagnosis by endosonography-guided fine-needle aspiration (EUS-FNA) is possible and has been reported in the literature in pancreatic tumors. However, its usefulness is still controversial. The aim of this study was to determine the accuracy of the EUS-FNA in the diagnosis of patients with SPN and describe the findings in computerized tomography (CT), magnetic resonance cholangiopancreatography imaging ( ...
