Urbanization, a dominant global demographic trend, leads to various changes in environments (e.g., atmospheric CO2 increase, urban heat island). Cities experience global change decades ahead of other systems so that they are natural laboratories for studying responses of other nonurban biological ecosystems to future global change. However, the impacts of urbanization on vegetation growth are n...

The global yeast autolysates and extracts industry is expanding dynamically, with annual market growth rates projected at over 8% from 2009 to 2015. Market drivers include the rapid growth of the processed food market. One of the main uses of yeast extract is as a natural ingredient for savory flavor creation and flavor enhancement, salt replacement, and nutritional profile enhancement of proce...

The composition of biologic molecules isolated from biominerals suggests that control of mineral growth is linked to biochemical features. Here, we define a systematic relationship between the ability of biomolecules in solution to promote the growth of calcite (CaCO3) and their net negative molecular charge and hydrophilicity. The degree of enhancement depends on peptide composition, but not o...

Forests in the middle and high latitudes of the northern hemisphere function as a significant sink for atmospheric carbon dioxide (CO2). This carbon (C) sink has been attributed to two processes: age-related growth after land use change and growth enhancement due to environmental changes, such as elevated CO2, nitrogen deposition, and climate change. However, attribution between these two proce...

The effect of human growth hormone (GH) and insulin-like growth factor-l (IGF-l), IGF-ll, and insulin on human plasma cell responses was studied. GH enhanced lg production and thymidine uptake in the human plasma cell lines, IM-9 and AF-10. IGF-l, but not IGF-ll or insulin, also enhanced lg production and proliferation in them. However, enhancement by GH was not mediated by IGF-I, because enhan...

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based ...

[1] Recently proposed ion-mediated nucleation theory suggests that the enhanced uptake of neutral polar molecules by the charged clusters as a result of dipole-charge interaction may be critical to the nucleation of particles in the atmosphere. A rigorous parameterization of the enhancement effect of dipole-charge interaction on the growth of charged clusters is presented and the important para...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

OBJECTIVE To identify the CT features that help differentiate gastric schwannomas (GS) from small (5 cm or smaller) gastrointestinal stromal tumors (GIST) and to assess the growth rates of both tumors. MATERIALS AND METHODS We included 16 small GSs and 56 GISTs located in the stomach. We evaluated the CT features including size, contour, surface pattern, margins, growth pattern, pattern and d...
