We investigate the role of hydrodynamics in the evolution of the morphology and the selection of kinematics in simple uniflagellated microorganisms. We find that the most efficient swimming strategies are characterized by symmetrical, nonsinusoidal bending waves propagating from the base of the head to the tip of the tail. In addition, we show that the ideal tail-to-head length ratio for such a...

good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...

This paper describes collaborative work on developing Indonesian WordNet in the AsianWordNet (AWN). We will describe the method to develop for collaborative editing to review and complete the translation of synset. This paper aims to create linkage among Asian languages by adopting the concept of semantic relations and synset expressed in WordNet.

abstract background: several case studies have described the use of the superficial inferior epigastric artery (siea) flap as a pedicled flap for reconstruction of upper and lower ex tremities, or a free fasciocutaneous flap when a large amount of skin coverage is required for hemifacial atrophy, breast or head and neck reconstruction. apparently, the anatomical findings of previous studies are...

Introduction: International Commission on Radiological Protection introduced three basic principles of radiation protection, namely justification, optimization, and dose limit. Medical exposure has no dose limits, and generally, diagnostic reference levels are used as a tool for optimization of patient protection. Material and Methods: Dosimetry was performed on 20 CT scanners located in 14 cit...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

background: dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. this study wasaimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. materials and methods: this prospective cohort study was conducted on 447 nulliparous women who referred to omolbaninhospital. several mat...

Let Z and IR (C) denote the ring of the integers and the field of real (complex) numbers, respectively. For a field F, we put i* = F\{0}. Fix A GC and B G C*, and let X(A, B) consist of all those second-order recurrent sequences {wn}neZ of complex numbers satisfying the recursion: n+i = „ ~ n-i (i.e., Bwn_Y = Awn wn+l) for n = 0, ± 1, ± 2,.... (1) For sequences in SE(A,B), the corresponding cha...
