background: abdominal circumference (ac), biparietal diameters (bpd) and femoral length (fl) are now the main parameters used to obtain estimated fetal weight (efw). although the role of soft tissue parameters in determining fetal weight was proved but clinical attention to mid-thigh soft tissue thickness (stt) is limited. objective: to find the impression of stt on birth weight (bw) and repres...

The effectiveness of an alpha-chloralose (AC)-corn oil suspension, an AC-margarine mixture, and AC tablets were compared for immobilizing Canada geese (Branta canadensis). Responses to AC immobilization also were compared in male and female Canada geese. There was no difference in mean time to first effects or mean time to capture between male and female geese dosed with 30 mg/kg AC in orally-a...

Ac–ac power conversion, the most popular topologies are indirect ac–ac converters with a dc link matrix converters and direct pulse width modulation (PWM) ac–ac converters. The indirect ac–ac converters and matrix converters can provide variable output voltage and variable frequency. However, for applications, where only voltage regulation is needed, the direct PWM ac–ac converters are used to ...

The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...

This study was conducted to compare the methods of seed bedpreparation in rangelands of Khash region in Sistan and Baluchestan province inIran. A split plot design was conducted based on Randomized complete blockdesign with three replications in 1999. Five seed bed preparation methods wereused as main plot as: 1) Seed sown by passing livestock. 2) Seed sown machinery.3) Seeds sown as drilled in...
