The distal arteriovenous fistula (AVF) has less complications and better patency than the proximal fistula, when it works properly. The complications of outflow of the fistula are complex, and it is necessary to analyze all solutions to solve the problem. We introduce a novel approach to solve outflow problems of a radio-cephalic AVF by straightening of the forearm cephalic vein with drainage into the median ba...

Introduction: Hemodialysis (HD) patients should be trained to develop selfcare behaviors in order to prevent and preserve their arteriovenous fistula (AVF). The aim of this study was identifying the factors that affect the levels of self-care behavior with AVF by HD patients. Methods: A cross-sectional study was conducted involving 89 patients. Results: Self-care levels were negatively affected by patients' loc...
Nos últimos anos, a cultura do morango tem vindo a assumir uma maior importância devido ao seu potencial de exportação e à elevada procura que se verifica, mas a sua curta vida útil dificulta a sua comercialização.
Assessment of leaf area is of fundamental importance to calculate diverse physiological parameters such as the total rate of transpiration or photosynthesis of a plant or its leaf area index (LAI). This paper reports the determination of total leaf area in 3 year-old olive trees of two varieties using four different methods and leaf counting as the control method. Leaf area was determined on 7 plants of each va...
The effect of nitrogen source application, broadcast onto the planting bed during the growing phase, on soil nitrate concentration, soil pH, yield, and quality of intermediate-day onions was evaluated in a field experiment in southern Portugal. In addition, the soil potential for providing nitrate-N to the crop along the growing season was also monitored. The field trial consisted of six treatments of different...
