The natural northern distribution limit for pedunculate oak ( L.) is in southern Finland. We hypothesized that the maximum frost hardiness (FH) winter limited cultivation of oaks latitudes. tested hypothesis with controlled freezing tests midwinter. The acorns experiment were collected from four main populations southernmost seedlings raised nursery, hardened field conditions, and then mo...

Global climate models simulate a robust increase of global mean precipitation of about 1.5 to 2% per kelvin surface warming in response to greenhouse gas (GHG) forcing. Here, it is shown that the sensitivity to aerosol cooling is robust as well, albeit roughly twice as large. This larger sensitivity is consistent with energy budget arguments. At the same time, it is still considerably lower tha...

The nasal placode shares a common origin with other sensory placodes within a pre-placodal domain at the cranial neural plate border. However, little is known about early events in nasal placode development as it segregates from prospective lens, neural tube and epidermis. Here, Dlx3, Dlx5, Pax6 and the pan-neuronal marker Hu serve as molecular labels to follow the maturation of olfactory precu...

Background: Feed is an important input for poultry and swine production, representing 50–70% of the total production costs. processing provides opportunity to improve performance. Herbal gut function modulators are used in feeds nutrient utilization efficiencies biomass production. Nbiotic™ Premix a phytoformulation AYURVET LIMITED, INDIA as natural growth promoter (NGP) effectively r...

â â â  in the last years, have been accelerated increased the damages of landslides by natural and anthropogenic factors. one of the main solutions to decrease landslide hazards is avoid from prone areas. for this purpose, it is necessary to prepare the landslide susceptibility map. in this research, after field studies in the ilam dam basin, nine factors including slope gradient, aspect, eleva...

C —¿ > T transitions at CpG sites are the most prevalent mutations found in the p53 tumor suppressor gene in human colon tumors and in the germline (Li-Fraumeni syndrome). All of the mutational hot spots are methylated to 5-methylcytosine, and it has been hypothesized that the majority of these mutations are caused by spontaneous hydrolytic deamination of this base to thymine. We have previou...

A number of reports have described the occurrence of liver cell adenomas in women using oral contraceptives. Circum stantial evidence derived from human and early experimental animal data, together with the recent report of Taper [Cancer (Phila.), 42: 462-467, 1978], suggests that oral contraceptive steroids may be liver tumor promoters. The objective of this study was to determine whether the ...

Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available observations. The characteristics examined include the mean spatial patterns, intraseasonal-to-interannual and ENSO-related variability, convective versus stratiform precipitation ratio, precipitation frequency a...
