This paper presents an analytic procedure for the value added to different production levels with different policy options. The approach is stochastic and thus provides a framework for informed decision-making on productivity growth under uncertainty conditions. The model was applied to data collected from a firm and re-sults recommend that the firm should redevelop if in diversification and sy...

Assessing the vulnerability of marine invertebrates to ocean acidification (OA) requires an understanding critical thresholds at which developmental, physiological, and behavioral traits are affected. To identify relevant for echinoderms, we undertook a three-step data synthesis, focused on California Current Ecosystem (CCE) species. First, literature characterizing echinoderm responses OA was ...

This research was conducted to evaluate the trend of cadmium accumulation in wheat tissue and cultivated soil affected conventional cropping systems and different growth stage via split plot experiment based on randomized complete block design with three replications during 2014-2015 seasonal year. The main factor included two cropping systems (wheat-rice, fallow-wheat) and growth stage at thre...

We conducted two laboratory experiments to evaluate the dietary effects of phytoplankton and zooplankton on larval survival, duration growth amphidromous atyid shrimp Atyopsis spinipes. In first experiment, commercially preserved or cultured Tetraselmis sp. rotifers were used rear larvae. second feed larvae for 17 days after hatching, which effect supplementing their diet with Artemia nauplii w...

small and medium size firms have major influence on job creation. some researchers, believe most of the new jobs are created in existed firms rather than newly established ones. growth management, could be the most important tactic for the firms future success. although it has many advantages for the firm, growth process faces some challenges. in this research, these challenges were identified,...

introduction: the role of adenosine a1 receptors of the entorhinal cortex on amygdaloid kindled seizures was investigated. material and methods: animals were kindled by daily electrical stimulation of amygdala. in the full kindled animals, n6-cyclohexyladenosine (cha; 0.1, 1 and 10 mm), an adenosine a1 receptor agonist, and 8-cyclopenthyle 1,3-dimethylexanthine (cpt), an adenosine a1 receptor a...

AIM To evaluate changes in indicators of endothelial function and their relationship with morphological forms of disease, stage of pathological process and tumor markers, by analysis the peripheral blood of lung cancer (LC) patients. MATERIALS AND METHODS 38 LC patients without metastases (mean age - 57 years) prior chemo- and radiotherapy were included in the study. The duration of the disea...

BACKGROUND AND AIMS Nitrogen (N) is a major factor affecting yield gain of crops under elevated atmospheric carbon dioxide concentrations [CO(2)]. It is well established that elevated [CO(2)] increases root mass, but there are inconsistent reports on the effects on N uptake capacity per root mass. In the present study, it was hypothesized that the responses of N uptake capacity would change wit...
