Background Bronchopulmonary dysplasia (BPD) is one of the most common serious squeal of preterm infants. It involves approximately one quarter of infants with birth weight less than 1500 grams and 30% of less than 1000 grams. Vitamin A has been shown to reduce BPD rate. We compared efficacy of low and high doses of vitamin A for prevention of BPD in very low birth weight preterm infants. Materi...

This study assessed hepatitis B prevalence among pregnant women attending health care facilities in rural Bangladesh. Blood samples were collected from 480 participants. HBsAg was positive in 0.4% of subjects, anti-HBc was positive in 21.5% and anti-HBs was positive in 8.5% of subjects. HBsAg was more prevalent among the older age group. Hepatitis B has a low prevalence among pregnant women in ...

strawberry as a very perishable fruit, is exposed to fungi pathogens especially botrytis cinerea, thus its storage life is very limited. the use of synthetic chemical compounds to control gray mold on strawberry as well as on other fruits that are directly consumed by humans, have become less and less advisable. on the other hand the use of non chemical and safe methods of controlling gray mold...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

$\beta$-Ga$_2$O$_3$ trench Schottky barrier diodes fabricated through a Gallium atomic beam etching technique, with excellent field strength and power device figure of merit, are demonstrated. Trench formation was accomplished by low-damage Ga flux etch that enables near-ideal forward operating characteristics independent fin orientation. The reverse breakdown greater than 5.10 MV/cm is demonst...
