the present work was carried out to investigate first, the ecology of the sepedon flies as well as speciesof lymnea snails and secondly, the biological effects of sepedon fly larvae living on lymnea. in this regard,the life cycle, death rate and compatibility of lymnea species, as well as the life cycle of sepedon flies inbreeding cage and the activity of the new larvae in the same ecological c...

The present work was carried out to investigate first, the ecology of the Sepedon flies as well as speciesof Lymnea snails and secondly, the biological effects of Sepedon fly larvae living on Lymnea. In this regard,the life cycle, death rate and compatibility of Lymnea species, as well as the life cycle of Sepedon flies inbreeding cage and the activity of the new larvae in the same ecological c...

background: the main object of this experimental work was to practise laboratory production both adult and the larval stage of hymenolepis diminuta with conventional modification to make further studies easier. materials & method: adults h. diminuta were collected from urban rats in tehran, iran. the beetles became infected using blended gravid segments with flour as bait. cysticercoids have be...

there are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. the mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. the quantum gates have been used to simulate these processes for the first time. the reason of several hundred sperms has been explained in the male too

The paper presents a new method of decision-making in conditions of severe uncertainty in application to a problem. The method has not been introduced in Poland yet and is still in the early development stage in Europe. Because the method is difficult to understand it was illustrated by the example of its application to evaluation of the project duration time. The paper also presents a proposal...

We introduce the half-cycle formulation (HCF), a new integer programming (IP) model for kidney exchange problem, which has life-saving applications. In HCF, cycle (i.e., set of swaps) is represented by two compatible halves. After giving several algorithmic enhancements we show through extensive computational experiments with an IP solver that our outperforms existing formulations when size lim...

this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...
