presently, emerging economies are acquiring singular positions all over the world. the complexities of nowadays economy have caused international companies and investors to be of a tendency towards emerging markets for more profitability and growth. this study aims to find the relationships between firm's profitability and growth in iranian manufacturing industry consisting of tehran stock...

To detect the presence of NO, ROS and RNS in nodules of crack entry legumes, we used Arachis hypogaea functional nodule. The response of two cognate partner rhizobia was compared towards NO and GSNO using S. meliloti and Bradyrhizobium sp NC921001. ROS, NO, nitrosothiol and bacteroids were detected by fluorescence microscopy. Redox enzymes and thiol pools were detected biochemically. Nitrosothi...

Treatment of Ehrlich ascites-tumour cells with 1-amino-oxy-3-aminopropane (AOAP), a potent inhibitor of ornithine decarboxylase, resulted in a marked decrease in cellular contents of putrescine and spermidine, concomitant with an arrest of cell growth. The activity of S-adenosylmethionine decarboxylase (AdoMetDC) was greatly increased in cells treated with AOAP. This increase in AdoMetDC activi...

7 We present a model of structural change due to non-linear Engel-curves for consumer 8 goods. Goods are sequentially introduced starting out as a luxury with high income 9 elasticity and ending up as a necessity with low income elasticity. Although this leads to 10 rising and falling sectoral employment shares, the model exhibits a steady growth path 11 along which the Kaldor facts are satisfi...

Introduction: Dental maturation is a useful indicator of growth. Moreover, skeletal maturation is assessed by the cervical vertebrae maturation (CVM) stages, using lateral cephalometric radiographs. This study aimed to investigate the association between Demirjian’s method and CVM stages and also to analyze the diagnostic performance of the dental maturation stages for identification of ...

Sexual size dimorphism (SSD) has received considerable attention from evolutionary biologists, but relatively little is known about the physiological mechanisms underlying sex differences in growth that lead to SSD. Testosterone (T) stimulates growth in many male-larger vertebrates, but inhibits growth in the female-larger lizard Sceloporus undulatus. Thus, opposite patterns of SSD may develop ...

Aims: Evidence has suggested that there might be negative consequences and benefits associated with maternal exercise while breastfeeding. The aim of the present study was to determine the effect of the exercise on lactation in breastfeeding women regarding whether mothers can exercise and breastfeed without detriment to the growth of their infants. Materials & Methods: In this randomized contr...

Complex systems may be mechanistically modelled by white-box modeling with using logical deterministic individual-based cellular automata. Mathematical models of complex systems are of three types: black-box (phenomenological), white-box (mechanistic, based on the first principles) and grey-box (mixtures of phenomenological and mechanistic models). Most basic ecological models are of black-box ...

Introduction: The purpose of this study was formulation and preparation of a proper culture medium for Saccharomyces cerevisiae var. boulardii with molasses and animal serum. Methods: A fully-crossed factorial design contain 5%, 10% and 20% of molasses (M) with 0, 1% and 5% animal serum (S) was used in this study. The pH of all culture medias were adjusted to 5.6 with acetic acid. The seed was ...
