1. Contributions of the High Frequency Dynamic Wire Feeding in the GTAW Process for Increased Robustness
Abstract: The GTAW process is recognized as a process of high metallurgical quality, being widely used in the pipelines welding, mainly in the root pass. The relative independence between the heat delivered to the melting pool and the amount of material added helps to control the melting of the material and to avoid the appearance of welding discontinuities

2. Penetration of 0.3% ciprofloxacin, 0.3% ofloxacin, and 0.5% moxifloxacin into the cornea and aqueous humor of enucleated human eyes
We aimed to quantify the penetration of ciprofloxacin, ofloxacin, and moxifloxacin into the cornea and aqueous humor of cadaver eyes. A total of 60 enucleated eyes, not eligible for corneal transplantation, were divided into three groups and immersed in commercial solutions of 0.3% ciprofloxacin, 0.3% ofloxacin, or 0.5% moxifloxacin for 10 min. Whole corneas

3. PENETRATION OF DROPS AND GRAIN YIELD IN ACCORDANCE WITH THE ARRANGEMENTS OF THE PLANTS CULTIVAR AND SPRAY VOLUME IN SOYBEAN CROP / PENETRAÇÃO DE GOTAS E RENDIMENTO DE GRÃOS EM FUNÇÃO DO ARRANJO DE PLANTAS, CULTIVARES E VOLUME DE CALDA NA CULTURA DA SOJA
Este trabalho teve como objetivo avaliar a penetração de gotas de pulverização e o rendimento de grãos em função da cultivar, do arranjo de plantas e volume de calda de soja em três estádios do ciclo da cultura. Para isso foram desenvolvidos dois experimentos na área experimental do Departamento de Defesa Fitossanitária da Universidade Federal de

4. Development of an electronic device for attraction drops of the electrostatic spraying in citric plants / Desenvolvimento de sistema eletrônico para pulverização e atração de gotas em plantas cítricas
The technology of application of agricultural defensives in tree like plants and orchard plants in general way, still little is researched in Brazil. Ahead of requirements of the international market, the application technology must take care of some parameters that will give the credibility of the Brazilian products in the exterior market, as for the certif

5. Formação de filme líquido nas paredes de um lavador venturi
The study of the liquid film in the walls of a Venturi scrubber was chosen as the target of this work for representing one of the important phenomena that influence the collection efficiency of the equipment. Such efficiency decreases with the presence of the film once it has a superficial area per volume much smaller than the drops and, consequently, contri

6. ROW SPACINGS AND SPRAY NOZZLES IN THE Phakopsora pachyrhizi Sidow CONTROL / ESPAÇAMENTO ENTRE LINHAS E PONTAS DE PULVERIZAÇÃO NO CONTROLE DE Phakopsora pachyrhizi Sidow
A associação da tecnologia de aplicação com o manejo fitotécnico pode proporcionar maior adequação no manejo fitossanitário assim como aumentar a exposição das folhas à radiação. O presente trabalho teve por objetivo avaliar o efeito da interação de espaçamentos entre linhas da soja com diferentes pontas de pulverização visando controle da

7. Effect of silicon on the resistance of corn plants to Rhopalosiphum maidis (Fitch.) (Hemiptera: Aphididae) and its interaction with insecticide in the control of Spodoptera frugiperda (J.E.Smith) (Lepidoptera: Noctuidae) / Efeito do silÃcio na resistÃncia de plantas de milho a Rhopalosiphum maidis (Fitch.) (Hemiptera: Aphididae) e sua interaÃÃo com inseticida no controle de Spodoptera frugiperda (J.E.Smith) (Lepidoptera: Noctuidae)
The action of pest insects is one of the factors responsible for the low level of yield of the corn in Brazil, and in this context, the corn aphid and the fall armyworm are considered the main corn pests. The control, chiefly, of the fall armyworm is accomplished almost exclusively by insecticide applications, which can cause, inclusive, damages to the envir

8. Influence of the weld parameters on metal transfer and weld bead profile in double wire MIG/MAG process / Influência da variação de parâmetros de soldagem sobre a transferência metálica e perfil do cordão no processo MIG/MAG duplo arame
Double Wire MIG/MAG welding process appeared in manufacturing market as an alternative for metals joining, when highest productivity is demanded. However, the most important limitations of this process is the difficulty for parameter settings, as much because of doubled parameters in relation to the normal process as because each wire is dependent of each ot

10. Modulation of fertilization in vitro by peptides released during hamster sperm-zona pellucida interaction.
The penetration of the zona-pellucida by hamster sperm in vitro (assay drops) was inhibited by aliquots of ultrafiltrates obtained from another set of drops (experimental drops) in which capacitated sperm had interacted with the surface of the zona pellucida. This inhibition was inversely related to the concentration of sperm in the assay drop, and it was no

12. Penetration of timolol eye drops into human aqueous humour: the first hour.
Samples of aqueous humour were removed from 26 eyes at the start of cataract extraction. Two drops of timolol 0.5% had been instilled into the conjunctival sac 12-71 minutes before operation. Analysis by gas chromatography showed a mean timolol concentration of 55.46 ng/mg, with a range of 8 to 100 ng/mg.
