In the present study, various developmental stages of Liza aurata oocyte, especially IV and V stages have been described. On the basis of histological investigations, oocyte development in L. aurata comprises immature (I), the early maturing (II), the late maturing (III), mature (IV), ripe (V), and spent (VI) stages. In the stages I and II, nucleus occupied large volume of oocyte. Vacuolization...

in this paper, we intend to investigate the impact of privatization on economic growth in developing and transition economies. previous studies that have attempted to measure this relationship have conflicting results, some indicating a positive impact of privatization on growth, while others indicate a negative relationship. our study uses recent world bank data on privatization for 117 countr...

the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

the effects of weight and length of barbus grypus broodstock on fingerlings reproductive characteristics and growth were investigated. we chose three female treatments  including weight and length groups (1) 2212.5±479g,  62.68±6.7cm, (2) 4518±780g,  79.12±4.36cm  and (3) 7712.5±1171g, 92.62±3.13cm. the same male broodstock were used for all the treatments with the weight and length size of 140...

Basic fibroblast growth factor (bFGF) induces proliferation and alters differentiation of cultured oligodendrocyte lineage cells. In situ, bFGF is present in normal adult central nervous system (CNS) and upregulated during an early stage of various pathological conditions. We examined the expression of receptors for bFGF (FGFRs) by oligodendrocyte progenitors and oligodendrocytes in situ in nor...

in order to study the effect of nitrogen on competition between wild oat (avena fatua) and wheat (triticum aestivum) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. first factor was five densities (0, 2, 4, 6 and 8 plan...

objective: this study investigated the relationship between resilience and religious orientation (internal and external) with posttraumatic growth (ptg). this study also examined the impact of marriage and sex variables on growth . method: participants were selected based on prescreening of a larger group of students enrolled in the university of shiraz. participants were recruited in two stage...

This paper explores the relationship between patterns of productivity growth and the development stage of an industry, using firm-level data on the cotton-spinning industry in Japan in the late-nineteenth century. It is found that patterns of productivity growth depend on the development stage of the industry. In the earlier stage of industrial development, the productivity growth of each firm,...

The pelagic juvenile stage of sea turtles is poorly studied. We present a growth model and estimates for duration of the pelagic juvenile stage for loggerhead sea turtles Caretta caretta in the North Atlantic based on length-frequency analyses and sizes of young-of-the-year stranded in the Azores. The size-specific growth model is a monotonic, nonlinear, declining function. The growth model is ...
