introduction: the parikh’s formula is a calculation method that considers menstrual cycle duration in women who have an unusual interval of menstruation cycle. since the accurate estimation of gestational age affects pregnancy outcomes, the present study aimed to compare the first trimester ultrasound and parikh’s formula in determining the expected date of delivery (edd). materials and methods...

Recently, Nüttgens and Rump proposed a formal semantics for Event driven Process Chains (EPCs), which should be fully compliant with the informal semantics of EPCs. But, their semantics has a severe flaw. This flaw reveals that there is a fundamental problem with the informal semantics of EPCs. Here, we pin-point the cause of this problem, we show that there is no sound formal semantics for EPC...

Covariance components for final score and 13 linear type traits of dairy goats were estimated by multitrait REML using canonical transformation with an animal model. Data were 10,932 type appraisals from 1988 through 1994 from herds with > or = 40 appraisals. Heritabilities were estimated as 0.27 for final score, 0.52 for stature, 0.29 for strength, 0.24 for dairyness, 0.38 for teat diameter, 0...

This study aimed to examine the nutrient utilization of rump round meat and lotus root using young (32 wk) and aged hens (108 wk) as an animal model. Rump round meat and lotus root were prepared with or without enzymatic treatment. For each age group of laying hens, a total of 24 Hy-Line Brown laying hens were randomly allotted to one of two dietary treatments with six replicates. For rump roun...

We investigated the effects of calpain-system genetic markers on consumer beef quality ratings, including interactions of marker effects with hormonal growth promotant (HGP) use and tenderstretch hanging. Brahman cattle in New South Wales (NSW; n = 164) and Western Australia (WA; n = 141) were selected at weaning from commercial and research herds to achieve balance and divergence in calpastati...

Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is certain and associated with a regular me...

Fourteen different morphological traits in 169 and 131 cattle of Oulmes-Zaer and Tidili, respectively were recorded and analyzed using a multivariate approach. The characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. Breed signif...

This study was performed to compare carcass traits, sensory characteristics, physiochemical composition, and contents of nucleotides, collagen, and free amino acids among quality grades (QG) and to understand the association between QG and above parameters in loin and rump of Korean cattle steer. Loin and rump samples were obtained from 48 Korean cattle steers with each of four QG (QG 1++, 1+, ...

A quantitative study of the trachea has been made in 452 children with apparently normal tracheas ranging from 28 weeks' gestation to 14 years. In the neonatal period the trachea is funnel shaped with the upper end wider than the lower end. It becomes cylindrical with increasing age. The ratio of cartilage to muscle remains constant throughout childhood. The trachea appears to grow at a greater...
