We study the properties of a future singularity encountered by a perfect fluid observer in tilting spatially homogeneous Bianchi cos-mologies. We derive the boost formulae for the Weyl tensor to establish that, for two observers that are asymptotically null with respect to each other, their respective Weyl parameters generally both tend to zero, constant, or infinity together. We examine three ...

Radiation is used to sterilize Medflies, Ceratitis capitata (Wied.), for SIT programmes. Massreared flies in the Madeira-Med sterile insect technique (SIT) programme are sterilized at the pupal stage about 24 hours before adult eclosion with 100 Gy using a Gamma Cell 220 loaded with Cobalt 60. The pupae are in anoxia/hypoxia when treated. It is known that the higher the radiation dose given to ...

Uranyl acetate dihydrate was tested for its effects on reproduction, gestation, and postnatal survival in Swiss mice. Four groups of animals, each of which consisted of 25 males and 25 females, were administered 0, 5, 10, and 25 mg/kg/day of uranyl acetate dihydrate. Mature male mice were treated orally for 60 days prior to mating with mature virgin female mice treated orally for 14 days prior ...

The objective of this study was to evaluate two protocols of estrous synchronization in non-lactating Toggenburg goats. Nineteen goats were allocated, according to body condition score and weight, into two groups (A and B) and evaluated utilizing two treatments (T1 and T2). Animals in the T1 and T2 groups received an intravaginal sponge (day 0) containing 60 mg medroxyprogesterone acetate for 6...

PLACE AND DURATION OF STUDY Army Medical College and Military Hospital, Rawalpindi, from February 2006 to January 2007. METHODOLOGY One hundred and sixty seven non-cirrhotic chronic hepatitis C patients...

Background: Anemia may be present in patients with chronic obstructive pulmonary disease (COPD) and further impair their functional capacity. Objectives: This study investigated the prevalence of anemia of chronic disease (ACD) in COPD patients and its impact on dyspnea and exercise capacity, utilizing cardiopulmonary exercise testing (CPET). Methods: ACD prevalence was assessed in 283 consecut...

BACKGROUND The purpose of the study was (1) to examine the changes in participation and performance of males and females at the Oita International Wheelchair Marathon in Oita, Japan, between 1983 and 2011, and (2) to analyze the gender difference in the age of peak wheelchair marathon performance. METHODS Age and time performance data for all wheelchair athletes completing the Oita Internatio...
