background: taxi drivers have the most important role in the public transport services. they are exposed to various harmful agents and occupational hazards. noise is a harmful occupational factors and hearing loss is its most important effect. protection of drivers against hearing loss is essential. this study was performed to determine the prevalence of hearing loss among taxi and agency drive...

This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...

BACKGROUND In this exploratory study, the contribution of delivery type to the weight gain pattern for full-term infants with exclusive breastfeeding in the first month of infancy was determined. In addition, breastfeeding success among cesarean section (C-section) delivery mothers based on their neonate's weight gain at the end of the first month of infancy was evaluated. METHODS A cohort of...

the object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. the evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. the results revealed that the effect of soil moisture content was only significant on...

Habitat loss through development is one of the major causes of biodiversity loss. The increasingly common legal requirement to first avoid, then reduce and, if necessary, offset impacts of plans and projects on biodiversity has however not always been appropriately enforced. The blame lies mainly in bad governance such as patchy monitoring or poorly defined liabilities. Biodiversity offsets als...

Results The prevalence of various pregnancy complications was 8. 6% for birth prematurely, 9. 2% for hypertension or preeclampsia, IUGR 5. 8% and 7. 3% for loss pregnancy. PAPP A levels were lower in fetal loss group (P = 0. 005), vascular disease group(P = 0. 001) and preterm delivery group(P = 0. 001). In addition, a lower rate of bHCG was associated with the occurrence of placental pathologi...
