PURPOSE To describe epidemiological findings of ocular trauma in childhood in an emergency unit. METHODS A retrospective study was carried out including patients under 16 years old who were treated for ocular trauma at the emergency unit of the Federal University of São Paulo from September 2001 to September 2004. Age, sex, involved eye, place, circumstance and mechanism of injury, initial vi...

Wood vinegar is a substance, derived from cooling black carbon fire, which could be used instead of chemical materials in the agriculture industry as an organic compound. In order to study the effectiveness of pine wood vinegar on physiological and photosynthesis traits of cucumber, two experiments were conducted based on a completely randomized design with six treatments including 0, 1250, 200...

To elucidate potential dose-dependent mechanisms associated with wood smoke inhalation injury, the present study evaluated antioxidant status and the extent of pulmonary injury in sheep after graded exposure to smoke. Adult, male sheep (n=4-5 per group) were anesthetized and received 0, 5, 10 or 16 units of cooled western pine bark smoke, corresponding to 0, 175, 350 and 560 s, respectively, of...

the major objectives of this study were to find out the mechanism behind the sapstaining fungal hyphae penetration into wood elements using electron microscope and to evaluate the exact role of phenolic compounds existing in wood vinegar towards the sapstaining fungal growth inhibition. to formulate the new environmental friendly wood preservative, we neutralized (to ph 7) wood vinegar with nao...

hemicellulose of southern yellow pine wood spices was extracted by pressurized hot water at three different temperatures: 140°c, 155°c and 170°c. compounding with pp (polypropylene) was performed by extrusion after preparing wood flour and sieving to determine its mesh size. the ratio of wood to polymer was 50:50 based on oven-dry weight of wood flour. all extraction treatments and control samp...

to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...
