1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
reserches show that relationship between human and residential places is based upo both emotional and identity structures. in other words, habitat place is not only the creator of a part of humanistic identity but also form a kind of sentimental and emotional bond that may result in tendency to maintain closeness to a specific place. therefor, formaton of emotional and identity relationship wit...
In order to evaluate effect of salinity on the germination and vegetative growth of grassland different salad burent Poterium sanguisorba two different experiments were conducted under laboratory and glasshouse conditions in summer 2010. In the first experiment six ecotypes (Semirom, Fereidonshahr, Tehran, Karsang, Damavand and farokhshahr) and four levels of salinity (0, 4, 8 and 12 dS m-1 of ...
a fundamental shift to a total system approach for crop management in greenhouses is urgently needed to resolve escalating economic and environmental consequences of long-lasting undesired effects of synthetic pesticides used in combating agricultural pests. the aim of this study was to examine a potential new approach i.e. microbial-based production system (mps) for greenhouse-grown peppers. f...
in order to study, the effect of pre-cooling treatment, osmotic potential and water stress on some population of two species of satureja bachtiarica and satureja sahendica was studied by a factorial experiment based on completely randomized design with three replications in laboratory and greenhouse conditions during one year in the gene bank of institute of forests and range lands by the years...
we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...

a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
it is well known that sugar beet is sensitive to salinity stress at the germination stage. three separate experiments were conducted to study the effects of salinity on seed germination, plant establishment, and yield of sugar beet genotypes for screening purposes. these included: (a) a laboratory study using four water salinity levels (with ec values < 0.1 as the control, 16, 20, and 24 ds m-1...
