Obtaining resistant lettuce progenies to downy mildew

A alface é a hortaliça folhosa mais consumida no Brasil. No entanto, a dificuldade em produzi-la vem aumentando, principalmente pela infestação das áreas de produção por Bremia lactucae, sendo o uso de cultivares com resistência horizontal, a alternativa mais viável no controle da doença. Diante do exposto, o objetivo do presente trabalho foi obter progênies de alface crespa resistentes às raças de míldio SPBl:01, SPBl:02, SPBl:03, SPBl:04, SPBl:05, SPBl:06 e SPBl:07. O trabalho de melhoramento consistiu de duas etapas: cruzamento dos parentais para obtenção das progênies de alface crespa resistentes e teste de resistência das progênies às raças de B. lactucae. Os parentais utilizados na obtenção das progênies resistentes foram Argeles e linhagem JAB 4-13-7, visando a obtenção de progênies de alface do tipo crespa, com os fatores de resistência R-18 e R-38. Para tanto, adotou-se o método genealógico, tendo como padrão, para as seleções, a cultivar Hortência e o genótipo JAB 4-13-7. Após a seleção e autofecundação das plantas no campo, efetuou-se o teste de resistência ou suscetibilidade, por meio da inoculação nas progênies oriundas dos cruzamentos, de uma mistura de água destilada + esporângios de B. lactucae das raças SPBl:01, SPBl:02, SPBl:03, SPBl:04, SPBl:05, SPBl:06 e SPBl:07 obtidas de isolados coletados nos anos de 2008 a 2010. Quinze dias após a inoculação, as plântulas foram selecionadas, descartando aquelas que possuíam esporulação e pontos necróticos causados por B. lactucae. Pelo método genealógico, selecionaram-se 69 progênies F3 com boas características agronômicas. No entanto, após o teste de resistência ou suscetibilidade, somente 19 apresentaram todas as plantas resistentes ao míldio.

Estudo de casos de seleção dos materiais e processos para a fabricação de fuselagens

This work proposes a study on the materials selections and processes for the manufacture of aircraft and showing a methodology to reduce the manufacturing cost. The DFMA can be understood as a methodology that aims at reducing manufacturing and assembly costs and coupled with the increase of product quality through design simplifications. The most commonly material used in the manufacture of aircraft is aluminum alloys due to these possess great structural strength, good elasticity, and being stainless having a low specific weight (about 1/3 that of steel), reducing the weight of the aircraft. A case study in which an operation in the process of verifying the quality was generating unnecessary costs time / man for the company was also developed. The problem solution was simple, just removing the attachment process. It was found that the DFMA methodology is extremely important for the simplification of processes and projects, contributing to the reduction of manufacturing costs of aircraft

On the solvability of implicit differential inclusions

In the paper, the set-valued covering mappings are studied. The statements on solvability, solution estimates, and well-posedness of inclusions with conditionally covering mappings are proved. The results obtained are applied to the investigation of differential inclusions unsolved for the unknown function. The statements on solvability, solution estimates, and well-posedness of these inclusions are derived.

Handgrip strength as a predictor of bone mineral density in cirrhotic outpatients

Osteoporosis is well recognized as a cirrhosis complication; however, most studies assessing this condition included only patients on liver transplantation lists with an elevated rate of bone diseases. While general population studies show that handgrip strength is clearly associated with bone mineral density, until now this tool has not been applied to cirrhotic patients in relation to their bone condition. This study aimed to evaluate whether handgrip strength, bone and liver tests may be useful as predictors of bone disease in cirrhotic outpatients. 129 subjects were included (77 men and 52 women). Dual energy X-ray absorptiometry was applied to evaluate lumbar-spine and femoral-neck T scores. Osteoporosis/osteopenia rates were 26.3%/35.6% in the lumbar spine and 6.9%/41.8% in the femoral neck, respectively. Model selections were based on backward procedures to find the best predictors of low T scores. For lumbar spine, only low handgrip strength and high parathyroid hormone levels were clearly related to low T scores. For femoral neck, only age was associated with low T scores. Handgrip strength may serve as an effective predictor of low lumbar spine T score among cirrhotic outpatients. As cirrhosis affects the lumbar spine more than the femoral neck, these results suggest that handgrip strength should be tested in all cirrhotic patients as a first indicator of bone health.

A modular approach to study protein adsorption on surface modified hydroxyapatite

Biocompatible inorganic nano- and microcarriers can be suitable candidates for protein delivery. This study demonstrates facile methods of functionalization by using nanoscale linker molecules to change the protein adsorption capacity of hydroxyapatite (HA) powder. The adsorption capacity of bovine serum albumin as a model protein has been studied with respect to the surface modifications. The selected linker molecules (lysine, arginine, and phosphoserine) can influence the adsorption capacity by changing the electrostatic nature of the HA surface. Qualitative and quantitative analyses of linker-molecule interactions with the HA surface have been performed by using NMR spectroscopy, zeta-potential measurements, X-ray photoelectron spectroscopy, and thermogravimetric analyses. Additionally, correlations to theoretical isotherm models have been calculated with respect to Langmuir and Freundlich isotherms. Lysine and arginine increased the protein adsorption, whereas phosphoserine reduced the protein adsorption. The results show that the adsorption capacity can be controlled with different functionalization, depending on the protein-carrier selections under consideration. The scientific knowledge acquired from this study can be applied in various biotechnological applications that involve biomolecule-inorganic material interfaces.

Selecting for rust (Puccinia psidii) reistance in Euclyptus grandis in São Paulo state, Brazil

In Brazil, Eucalyptus grandis is a key species for wood production. However, some genotypes are susceptible to rust (Puccinia psidii), mainly in São Paulo State, where climatic conditions are favorable for its development. Rust represents a high economic risk to forest companies because of the high potential of damage to commercial eucalypt plantations. The aims of the present study were (i) to select progenies of E. grandis for stability and adaptability regarding resistance to rust at different locations; (ii) compare the selections under these different climatic conditions; and (iii) compare rust severity in the field with the theoretical model. We observed that climatic conditions were extremely influential factors for rust development, but even under favorable conditions for disease development, we found rust-resistant progenies. In sites unfavorable for rust development, we detected highly susceptible progenies. We found significant correlation among the genetic material, environmental conditions and disease symptoms, however, we observed a simple genotype-environmental interaction and significant genetic variability among the progenies. The average heritability was high among the progenies in all sites, indicating substantial genetic control for rust resistance. We also observed a good relationship between rust severity in the field and the theoretical model that considered annual average temperature and leaf wetness.

The soccer is a sport that can be decided in a penalty, including world champions have already been defined For this, shoot a penalty or defend a penalty can build heroes and villains in this sport so popular and competitive. Studying penalty kicks will a better understanding of the actions of goalkeepers and kickers. This study looked at 527 penalty charges in professional games in 2010 to 2015. The objective was to verify the fact that the charge be right-handed or left-handed interfered with the action of the goalkeeper, differences in efficiency of left-and right-handed players, check results in penalty situations in the match and in the disputes of penalties and performance of players in club games and selections. The complete use in 527 penalty charges was 74%. It is concluded that if the debt collector is right-handed, the goalie moves to the right and if it's left-handed move more to the left. Tax collectors selections had better use (77%) than the clubs. Right-handers presented more efficacy (76%) compared to lefties (66%). The index of the goalkeepers was greater when centered (22%), although 91% of all charges being directed to the right and left sectors
