Several animal models of "depression" have been examined. One of them is chronic unpredictable stress (CUS)-induced deficit of fighting behavior in rats. In the present study, we compared the effects of two antidepressants (fluoxetine or fluvoxamine) and three anxiolytics (buspirone, lorazepam or oxazepam) on the electric footshock-induced fighting behavior in the pairs of male Wistar rats expo...

In this paper we have designed, developed and proposed a prototype Wireless Sensor Network (WSN) System to monitor the Fish Farm. Salinity of the fresh water is a prominent parameter and is responsible for the difference in environment from marine conditions. Salt is an effective ingredient for fishes in fighting disease, parasites and chemical poisoning. The pH is equally a key parameter which...

In nature animals fight to acquire or defend vital resources such as food, shelter or access to mates. Aggressive behaviour is a quantifiable response to social stress, which is intrinsic to an individual and prevalent throughout the animal kingdom. In dyadic agonistic encounters, behaviour can be characterized by several specific behavioural patterns, usually dependent on the actions of the op...

OBJECTIVE To analyze the impact of the method of Gunshot Injury (GSI) (i.e. war injuries, stray bullets, and civilian fighting) on patient morbidity and mortality. STUDY DESIGN An observational study. PLACE AND DURATION OF STUDY Biostatistics Department of Al-Jalaa Hospital in Benghazi, Libya, from January to December 2011. METHODOLOGY Patients' records were analyzed with the method of gu...

The physical demands of rapid and economical running differ from those of physical fighting such that functional trade-offs may prevent simultaneous evolution of optimal performance in both behaviours. Here we test three hypotheses of functional trade-off by measuring determinants of limb musculoskeletal function in two breeds of domestic dogs that have undergone intense artificial selection fo...

This paper proposes an optimization algorithm based on how human fight and learn from each duelist. Since this algorithm is based on population, the proposed algorithm starts with an initial set of duelists. The duel is to determine the winner and loser. The loser learns from the winner, while the winner try their new skill or technique that may improve their fighting capabilities. A few duelis...

Levels of three adrenal catecholamine synthesizing enzymes and isolation-induced fighting behavior were studied in two related sublines of the Balb/c inbred mouse strain. Enzyme levels were twice as high in the adrenals of Balb/cJ mice as in those of the Balb/cN mice; heterozygous progeny were intermediate between their parents in the levels of the three enzymes. These sublines also showed mark...
