objective: this study aimed to evaluate the effect of seasonal variability on the assisted reproductive technique (art) success rate. materials and methods: this study was a descriptive – analytical survey performed on 91 infertile women undergoing  intracytoplasmic sperm injection – embryo transfer (icsi-et) in different seasons. the patients aged less than 35 years old and had normal lh/fsh r...

absracta rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. the superior root of the ansa cervicalis was formed by the c1 ventralramus. it accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. moreover the c1 ventral ramus formed fromthe sheath and joined the inferior root from c2 and c3 ventr...

eight pollinators (as pollen parents) and four cms lines (as seed parents) differing in salinity and drought tolerance were evaluated using agro-morphological traits and microsatellite markers. root yield, leaf weight, sugar content, sodium content (na+), potassium content (k+), a-amino nitrogen content, alkalinity coefficient, molasses sugar, white sugar content, extraction coefficient of suga...

the main purpose of this study was to evaluate the influence of the photoperiod on the seminal traits of crossbreed wool-producing rams throughout on year period. for the effect of photoperiod two periods were considered: decreasing daylight length (summer and autumn) and increasing daylight length (winter and spring). for the study 5 baluchi × moghani (bl×mg) and 5 arkharmerino × moghani (am×m...

in this study, the genetic diversity among paecilomyces variotti isolaes was investigated. sampling was performed from pistachio garden in seven geographical region of kerman province during 2011-2012. seventy isolates were identified as p. variotii species using morphological criteria. the genetic diversity among 20 selected isolates was assayed by variation at ssr marker bands using 12 pair p...

An important step in plant breeding programs is identification of parents that are geneticallydistant from each other, to find crossing combinations with better prospects of hybrid vigor. Thepotential of identifying genetically distant parents depends on genetic diversity of population. 58 linesof rice from diverse origins have been employed to study genetic variation in order to identify themo...

Abstract. We prove a BV estimate for scalar conservation laws that generalizes the classical Total Variation Diminishing property. In fact, for any smooth function Φ, we have that Φ(u) is TVD with the correct definition of the initial seminorm. We call this property Total Oscillation Diminishing. The reason being that it is in contradiction with the oscillations observed recently on some numeri...

the japanese and english white quails are widespread strains and belongs to the galliformes order, phasianidae family, coturnix genus  and japonica species. these birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. in the current study, the genetic variation of japanese and english white  quail ...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...
