The use of ultrasonography has significantly improved the evaluation of fetal growth and development and has permitted prenatal diagnosis of a variety of congenital malformations.Campbell et al in (1968) studied fetal cephalometry in the second trimester and determined that the fetal head can be measured from 13 week of pregnancy2. BinholzJ.C(1982) studied the new born cerebellar size both in f...

background: stereotactic radiosurgery is an important clinical tool for the treatment of small lesions in the brain, including benign conditions, malignant and localized metastatic tumors. a dosimetry study was performed for elekta ‘synergy s ’ as a dedicated stereotactic radiosurgery unit, capable of generating circular radiation fields with diameters of 1-5 cm at isocentre using the beam/egs4...

background: considering differences in head size and shape of different equine breeds, biometric parameters can be an attribute to a particular race. objectives: the purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the darehshori horse. methods: twenty mature darehshori horses were studied biometrically. the ear length, ears dista...

The characterization of flow through Pelton hydro turbines allows the optimization their operation and maximization energy performance. in injector free jet area (the from outlet surface to runner bucket inlet surface) is influenced by several parameters: geometry components (nozzle spear), opening, turbine head. parameters (velocity distribution, pressure spread) are reflected efficiency. rese...

Sex determination based on discriminant function analysis of skeletal measurements is probably the most effective method for assessment of sex in archaeological and contemporary populations due to various reasons, but it also suffers from limitations such as population specificity. In this paper standards for sex assessment from the femur and tibia in the medieval Irish population are presented...

Pancreatoblastoma (PB) in children is extremely rare. Although pancreatoblastoma in children has been well reported in some literature, very few cases have been reported in China. In this paper, we report a case of pancreatoblastoma. This patient was a 4-year-old girl who complained of abdominal pain for a week. Imaging studies showed an about 5 cm in diameter mass located at the head of pancre...

Yield and relationships among head traits were recorded in order to better understand the effects of planting date and cultivar selection on crop quality characteristics and to help increase the efficiency of cultivar development, evaluation, and selection. A total of seven cultivars of fresh market-type cabbage (Brassica oleracea L., Capitata Group) were planted in May and June of 1999 and 200...
