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

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...

urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their environmental impact. in a life cycleassessment (lca) the conventional production was used as a yardstick against which tomeasure the performanceof two recycling options: spreading of sewage sludge and phosphorus recovery from municipal ...

magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...

waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...

transportation is an important part of modern community life as well as one of the largest sources of greenhouse gas emissions in urban communities, the population growth of which can increase transportation capacity. monorail systems are relatively new rail transportation systems which are currently being designed and constructed in different countries. we have applied the intergovernmental pa...

background: human echinostomiasis is an intestinal disease caused by the members of family echinostomatidae parasites. the aim of present research was to identify echinos­tomatidae cercariae emitted by lymnaea palustris snails from mazandaran province in the north of iran based on the morphological and morphometrical charac­teristics of the different stages of experimental parasite life cycle. ...
