We have studied the expression of G protein subtypes and the role of G protein-dependent signaling in two subclones of RED-1 cells, an erythropoetin(Epo)-sensitive, murine erythroleukemia cell line. Clone 6C8 showed terminal erythroid differentiation in response to a combined treatment with Epo and dimethylsulfoxide. Clone G3 was resistant to these inducers, but responded to Epo with enhanced p...

mold powders used in the continuous casting of steel contain the harmful caf2 as a main substance developing toxic gases such as sif4 and hf at elevated temperatures. in this study, three samples of i1, i2 and i3, which contained gypsum free portland cement clinker with different percentages of fe2o3 (5.68, 6.83, 8.02 ) and f- (2.09, 1.06, 0), were prepared and their main characteristics were c...

abstract in order to study the effects of cultivation method and water quantities in drip irrigation on yield of potato, an experiment was carried out using a split plot based on randomized complete block design with 4 replications in torogh agricultural research station (mashhad, iran) for tow years (2001 and 2002). the main-plots were divided into 3 levels of irrigation: i1= 100, i2= 80 and i...

The development of new approaches for sustaining soil quality, leaf health, and maize productivity are imperative in light water deficit salinity. Plant growth-promoting rhizobacteria (PGPR) silica nanoparticles (SiNP) expected to improve chemistry leading improved plant performance productivity. In this field experiment, is imposed by three irrigation intervals—12 (I1), 15 (I2), 18 (I3) days. ...

The articles [15], [8], [9], [10], [14], [11], [18], [2], [4], [6], [7], [5], [16], [1], [3], [19], [20], [12], [17], and [13] provide the notation and terminology for this paper. For simplicity, we adopt the following rules: a, b are data-locations, i1, i2, i3 are instruction-locations of SCM, s1, s2 are states of SCM, T is an instruction type of SCM, and k is a natural number. We now state a ...

The ventral premotor area (F5) is part of the cortical circuit controlling visuomotor grasp. F5 could influence hand motor function through at least two pathways: corticospinal projections and corticocortical projections to primary motor cortex (M1). We found that stimulation of macaque F5, which by itself evoked little or no detectable corticospinal output, could produce a robust modulation of...

We introduce a new approach to an enumerative problem closely linked with the geometry of branched coverings, that is, we study the number Hα(i2, i3, . . . ) of ways a given permutation (with cycles described by the partitionα) can be decomposed into a product of exactly i2 2-cycles, i3 3-cycles, etc., with certain minimality and transitivity conditions imposed on the factors. The method is to ...

The present study was undertaken to investigate the sedative, analgesic and clinical effects of xylazine, medetomidine and dexmedetomidine with fentanyl as pre-anaesthetics in water buffaloes and to compare the dose-sparing effect of xylazine, medetomidine and dexmedetomidine on thiopental for induction and isoflurane for maintenance of anaesthesia in water buffaloes. Six male water buffaloes r...

A common issue in forest management is related to yield projection for stands at young ages. This study aimed evaluate the Clutter model and artificial neural networks projecting eucalypt production from early ages, using different data arrangements. In order do this, changes number of measurement intervals used as input (ANNs) are tested. The was fitted considering two sets data: usual, with i...
