    Re-Scaling of Energy in the Stringy Charged Black Hole Solutions using Approximate Symmetries

    Full text link
    This paper is devoted to study the energy problem in general relativity using approximate Lie symmetry methods for differential equations. We evaluate second-order approximate symmetries of the geodesic equations for the stringy charged black hole solutions. It is concluded that energy must be re-scaled by some factor in the second-order approximation.Comment: 18 pages, accepted for publication in Canadian J. Physic

    Baiting technique if appropriately applied is the most reliable strategy to control rodent pests. Behavior modifying components may play a significant role in developing the most attractive baits. An attempt was therefore made to investigate the behavior revolutionizing effect of taste enhancers including peanut oil, peanut butter, egg shell and fishmeal, on exploratory approaches of rodents. Precise role of additives and impact of particle size of cereal bases has been discussed aiming to minimize bait shyness, neophobia and development of the most preferred bait combination for effective control of bandicoot rat Bandicota bengalensis.Key words: Bandicota bengalensis, cereals baits, taste enhancers, shyness, neophobia

    Perforated Duodenal Ulcer in Pregnancy—A Rare Cause of Acute Abdominal Pain in Pregnancy: A Case Report and Literature Review

    Medical and surgical disorders in pregnancy can be can be quite challenging for the obstetrician gynaecologist even in resource rich countries. Reaching an accurate diagnosis and admininstering appropriate management can be difficult in the presence of an on-going pregnancy. The importance of involving specialist from other disciplines (multidisciplinary care) cannot be overemphasized. We present an interesting case of perforated duodenal ulcer in a pregnant patient, review the literature ,discuss the differential diagnosis and evaluate the management principles for this rare condition
