Impact factor in 2000 the usual way of expressing citation frequency, but has the advantage that it permits easier comparison of the impact Fig. 1 shows that Cardiovascular Research will score an of consecutive year volumes of the journal. Fig. 2 shows all time high impact factor of 3.59 in the year 2000. This an optimum for the citation frequency of the 1995 contents impact factor reflects the...
Aspiration of meconium produces a syndrome (Meconium Aspiration Syndrome MAS) characterized by hypoxia, hypercapnia, and acidosis. Perinatal hypoxia, acute airway obstruction, pulmonary inflammation, pulmonary vasoconstriction, pulm onary hypertension, and surfactant inactivation all play a role in the pathogenesis of MAS. Most aspiration of meconium probably occurs before birth. Following asp...
Male inbred F344 weanbing rats were fed semipunified diets containing 20 or 5% beef fat. At 7 weeks of age, all animals except controls were given 1,2-dimethylhydrazine [DMH (150 mg/kg body weight s.c.; one dose)], methyl azoxymethanol acetate [MAM acetate (35 mg/kg body weight i.p.; one dose)], or methylnitrosourea (2.5 mg/rat/ week intrarectally; two doses), and autopsied 35 weeks later. No m...
40 The distribution of neuronal characteristic frequencies over the area of primary 41 auditory cortex (AI) roughly reflects the tonotopic organization of the cochlea. 42 However, because the area of AI activated by any given sound frequency in43 creases erratically with sound level, it has generally been proposed that fre44 quency is represented in AI not with a rate-place code, but with some ...
quency of plasma spacing, blocking of blood flow in varying numbers of nutritive capillaries, shunting of blood from arterioles to venules . . . . ” These microcirculatory changes were said to result in a decrease of nutritive blood flow in tissue. As mentioned in the discussion of CHD, Kjeldsen ( 31, 32) studied several smoking patients with occlusive peripheral vascular disease whose COHb lev...
The inilnû oncogene encodes a 90-kDa nuclear phosphoprotein that binds and inhibits the function of the p53 tumor suppressor protein. It was recently reported that the expression of alternatively spliced variants of uiclm2 correlated with malignancy in ovarian tumors and bladder carci nomas. We analyzed the presence of alternatively spliced mdm2 variants and studied their correlation to p53 st...
the purpose the present is the citation and co-authorship analysis of the islam and quranic science researchers in “web of science” database and mapping the scientific structure of this domain between years of 1993–2012.this research is applying and we use scientometric methods and some rules and procedures related to this domain,. histcite™ software was utilized to mapping the structure of sci...
given the sensitivity of current ground-based gravitational wave (gw) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. hence, any data analysis of detector data will need to rely on statistical techniques to separate the signal from the noise. while with the current sensitivity of our detectors we do not expect to detect any tru...
cognitive science has found out that languages typically make use of conceptual metaphors to concretize abstract meanings. conceptual metaphor explains a target domain which is abstract via a source domain which is concrete. in other words, conceptual metaphor compares an abstract domain with a concrete one and thus makes it understandable for listeners/readers. this article studies the concept...
fe49co33ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 oe and 0.58 to200 oe and 0.105, respectively), indicating the increase in m...
