Renet Simirenko grafted on M.4 or M.9 rootstocks, the plots were sprinkler irrigated with water from an artesian well to maintain soil moisture at 70-80% of field capacity. Application frequency and rates, and the charac...

Genetic counselling in families with congenital hydrocephalus internus (CHI) in combination with aqueduct stenosis (AS) is often difficult due to an uncertain aetiology. We present a series of 35 patients with CHI and AS focusing on the aetiology...

Ju, Y.Chan.; Kim, S.; Seong, T-Geun.; Nahm, S.; Chung, H.; Hong, K.; Kim, W., 2012: Resistance random access memory based on a thin film of CdS nanocrystals prepared via colloidal synthesis. We demonstrate that resistance random access memory (RRAM) can be fabricated based on CdS-nanocrystal thin films. A simple drop-drying of the CdS-nanocrystal solution leads to the formation of uniform thin films with controlled thickness. RRAMs wi...

This anemia appears to be due largely to a blunted erythropoietin (Epo) response and an impaired ability of the bone marrow to respond to endogenous Epo. Both a...

Tropomyosin ( Tm) is a dimeric coiled-coil protein, composed of 284 amino acids ( 410 A), that forms linear homopolymers through head-to-tail interactions at low ionic strength. The head-to-tail complex involves the overlap of approximately nine...
