Pregnant rabbits (Day 18) were treated i.m. for 3 days with 10 microgram oestradiol 17beta/kg. The number of dead fetuses was significantly greater than in the control animals but corpus luteum weight and peripheral progesterone concentrations were not affected. Fetal death was therefore not due to luteolysis.

Acute radiation sickness (ARS) following exposure to ionizing irradiation is characterized by radiation-induced multiorgan dysfunction/failure that refers to progressive dysfunction of two or more organ systems, the etiological agent being radiation damage to cells and tissues over time. Radiation sensitivity data on humans and animals has made it possible to describe the signs associated with ...

This study aimed to evaluate greenhouse gas (GHG) emissions from conventional cultivation (S1) of seedless lime (SL) fruit in Hau Giang province, the Mekong Delta region Vietnam. We adjusted scenarios by replacing 25% and 50% nitrogen chemical fertilizer with respective amounts N-based organic (S2 S3). Face-to-face interviews were conducted collect primary data. Life cycle assessment (LCA) meth...

This paper describes an outbreak of dermatitis among stevodores at a port handling cement. The cement was imported in bags, and because of breakage, there was much spillage. It was also hot and dusty inside the hatch of the ship, and some of the stevodores worked bare-bodied. Cases of dermatitis began to appear in January 1983 and reached a peak in April 1983, gradually subsiding over the next ...

Although the full effects depend on the way that firm-level special tax regimes are designed, special regimes generally tend to favor pass-through...

Use of herbal remedies in pregnancy may be deleterious to both mother and fetus. Against this background, aqueous and ethanol root bark extracts of Salacia lehmbachii, widely used herbal remedies for treatment of malaria in some localities were evaluated for embryotoxicity and teratogenicity in albino rats. One hundred and five pregnant rats weighing 170-180g were assigned 7 groups (n=15), labe...

This paper presents a set of robust PI tuning formulae for a first order plus dead time process using particle swarm optimization. Also, tuning formulae for an integrating process with dead time, which is a special case of a first order plus dead time process, is given. The design problem considers three essential requirements of control problems, namely load disturbance rejection, setpoint reg...
