1. The Formation Mechanism of Porosity for Spray-deposited 7075 Alloy
The distribution model of temperature for the billets was established based on the porosity formation mechanism. By calculating the numerical relationship between the temperature of the deposition layer and the formation ability of the porosity, the distribution of porosity for spray formed 7075 aluminum billets was predicted and the influence of superheat o

2. Automatização de um pulverizador hidropneumático visando o controle do espectro de gotas em função do déficit de pressão de vapor dágua do ar / Automation of a hydro-pneumatic sprayer for controlling droplet spectrum in function of deficit of water vapor pressure in the air
Pesticide spraying is one of the most repeated operations in farms, this has occurred mainly due to adoption of no tillage. Facility for purchasing pesticides is notorious throughout Brazil. However, technology for its application has been difficult to reach the producers, even in regions with high agricultural potential. This work aimed to develop a system

3. Tecnologia de aplicação aérea e terrestre na cultura da batata / Aerial and ground application technology in potato crop
A batata é a principal olerícula cultivada no Brasil, porém apresenta grandes desafios quanto à tecnologia de aplicação de fitossanitários. A alta frequência de aplicações desses produtos, principalmente fungicidas, é a grande responsável pelo seu elevado custo de produção. Dessa forma, é necessário estudar métodos que otimizem a tecnologia

5. Technical parameters for the white mold control using air- assisted hydraulic sprayer / Parâmetros técnicos para o controle do mofo-branco na cultura do feijão utilizando pulverizador hidráulico de barra com assistência de ar
The white mold, caused by the fungus Sclerotinia sclerotiorum, is one of the most destructive diseases of the bean plant in the world, especially in crops under conditions of mild temperatures and high soil and air humidity. In general, primary infections caused by this fungus start due to the presence of free water and an exogenous energy source, usually se

7. Resíduos de fenitrotion e esfenvalerato em grãos de milho e trigo, em alguns de seus produtos processados e sua ação residual sobre Sitophilus oryzae (L., 1763), Sitophilus zeamais Motsch.,1855 (Coleoptera: Curculionidae) e Rhyzopertha dominica (Fabr.,1792) (Coleoptera: Bostrichidae) / Fenitrothion and esfenvalerate residues in corn and wheat grain and in some of their processed products, and residual action on Sitophilus oryzae (L., 1763), Sitophilus zeamais Motsch., 1855 (Coleoptera: Curculionidae), and Rhyzopertha dominica (Fabr., 1792) (Coleoptera: Bostrichidae)
Because of the problems caused by insects in storehouses, chemicals have been chiefly used in Brazil to control these pests. However, success in solving problems with pests has been limited. In view of this, some aspects about stored grain protection were studied, among which are the following: 1) spray volume effect on grain moisture content, 2) stability o

8. Deposition of spray solution in the soybean crop according the type of nozzle and volume applied / DeposiÃÃo da calda de pulverizaÃÃo na cultura da soja em funÃÃo do tipo de ponta e do volume aplicado
To prevent the losses in agriculture has been the great objective of the Engineers Agronomists, as well as professionals of other similar areas of agrarian sciences that are worried very about the losses in agriculture, including the fitossanitÃria area. Most of the time, during the chemical control of plagues, harmful illnesses and plants, give to much imp

9. Modified Spinning Top Homogeneous Spray Apparatus for Use in Experimental Respiratory Disease Studies
The May spinning top generator was adapted to a modified Henderson tube for producing large aerosol particles (>4 μm) to obtain almost exclusive upper respiratory tract deposition of infectious aerosols in exposed mice. The system was installed in a biological safety cabinet to permit experimentation with pathogens. A novel mechanism utilizing parts from a

10. Pressurised aerosol deposition in the human lung with and without an "open" spacer device.
A radiotracer technique has been used to assess aerosol delivery from a pressurised metered dose inhaler, used both with and without a 10 cm cylindrical spacer attachment (Syncroner), which has an open section in its upper surface. The radionuclide technetium-99m (99mTc) was added to sodium cromoglycate in a canister (Intal inhaler; 1 mg/puff); in vitro stud
