We study the effects of scattering lengths on Lévy walks in quenched, one-dimensional random and fractal quasilattices, with scatterers spaced according to a long-tailed distribution. By analyzing the scaling properties of the random-walk probability distribution, we show that the effect of the varying scattering length can be reabsorbed in the multiplicative coefficient of the scaling length. ...

AIM Thecurrent study aims at investigating the polyadenylated (poly[A]) tail length of morphologically high and low competent oocytes at different developmental stages. Furthermore, effect of ultra-rapid vitrification on the poly(A) tail length was studied. MATERIALS AND METHODS Fresh bovine cumulus oocyte complexes from abattoir originated ovaries were graded based on morphological character...

polyvinylidene fluoride/polyvinylpyrrolidone (pvdf/pvp) hollow fiber membranes were fabricated by dry-jet wet-spinning process. the correlated effects of the air gap length and pvp concentration ((1) the air gap length effect at the low and high pvp concentration in the dope solutions, as well as (2) the effect of the pvp concentration at the same air gap length) on the cross-section structure ...

root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...

The purpose of this study was to determine the taxonomic status of an unidentified enigmatic macaque seen by scientists since the late 1990s in Arunachal Pradesh, India. We surveyed 49 troops of enigmatic macaques in four districts of Arunachal Pradesh. The population studied is from the macaque sinica-group as defined by the reproductive organs. The main species-separating trait in the sinica-...

Tail morphology in primates is important for interpreting functional adaptation and phylogeny. Tail length is probably the most remarkable trait. Establishing usable methods to predict the tail length of extinct primates is a part of the basis to reconstruct primate evolution, particularly of hominoids. Previous studies revealed that sacral morphology often predicts tail length. However, most o...

Background: Matricaria chamomilla (chamomile) is a herb used to treat various human illnesses. The present study was conducted to investigate the effects of chamomile extract on spermatozoon quality, serum levels of estradiol and testosterone, and sperm tail length in male adult rat.  Methods: Male Sprague-Dawley rats received extract of chamomile (400 mg/kg once daily, orally) during an 8-week...

Fluid slip has been observed experimentally in microand nanoscale flow devices by several investigators @e.g., Tretheway and Meinhart, Phys. Fluids 14, L9 ~2002!; Zhu and Granik, Phys. Rev. Lett. 87, 096105 ~2001!; Pit et al., Phys. Rev. Lett. 85, 980 ~2000!; and Choi et al., Phys. Fluids 15, 2897 ~2003!#. This paper examines a possible mechanism for the measured fluid slip, for water flowing o...
