Nipponbare）. Genetic analysis indicated that the phenotype was caused by a recessive mutation in a single nuclear-encoded gene. To map the PGL2gene, an F2 population was constructed by crossing the mutant with Longtefu （Oryza sativa L. subsp, indica）. The PGL2 locus was roughly linked to SSR marker RM331 on chromosome 8. To finely map the gene, 14 new InDel markers were developed around the marker, and PGL2 was further mapped to a 2.37 Mb centromeric region. Analysis on chlorophyll contents of leaves showed that there was no obvious difference between the mutant and the wild type in total chlorophyll （Chl） content, while the ratio of Chl a / Chl b in the mutant was only about 1, which was distinctly lower than that in the wild type, suggesting that the PGL2 gene was related to the conversion between Chl a and Chl b. Moreover, the method of primer design around the centromeric region was discussed, which would provide insight into fine mapping of the functional genes in plant centromeres.展开更多

We conducted sedimentological and stratigraphic investigations in the northeastern Qiangtang terrane, eastern Tibetan Plateau. Our results indicate development of several nonmarine basins during Paleogene(?) time, probably synchronous with northeast\|southwest contractional deformation. The Nangqian and Xialaxiu basins (96°～97°E, 32°～33°N) are composed of 500～ 20000m thick successions of primarily clastic sediment indicative of lacustrine and alluvial\|fan depositional processes. Paleocurrent measurements and sediment compositional data indicate local sediment source areas composed of Carboniferous\|Triassic carbonate and sandstone and minor Tertiary volcanic rocks. The large variability of provenance and facies types suggest that each basin evolved independently, as opposed to regional development of a single integrated basin which was partitioned by later deformation.展开更多

Years elapsed, the"who invented whom"question remains an enigma. Through expounding four current interpretations and tracing the relationship among the major characters, the real author behind this intriguing work—Nabokov is reshaped. Meanwhile, several fundamental ideas prevalent in his literary creation are discussed, casting some light on the philosophy behind his literary creation.展开更多

We can find a vivid embodiment of this creation view in Pale Fire. Because of the method“defamiliarization”, the aesthetics of the whole novel is expressed in three key steps: the introduction of poeticambiguity on Shade’s poem;an explanation of poetic ambiguity by means of Kinbote’s commentary;regenarationof ambiguity through the suspension of Kinbote’s commentary from Shade’s poetic language. The artistic theme ofambiguity is a manifestation of the author’s hidden feelings for the homeland. Nabokov, as an expatriate Russianwriter, is experiencing not only a deep relationship with his homeland, but also a sense of bitterness from being inexile. His impression and memories of hometown beacame the inspiration for creation.展开更多

Vascular occlusion is one of the most serious complications. The need urges to adopt a powerful protocol to manage such cases. The private practice I am working for has six branches in the middle east. I tried to investigate if there were any vascular occlusion incidences through the last three years. Four cases without sufficient details were found. A protocol was adopted from a scientific reference to deal with similar cases properly. A re-audit was done after six months to test the efficiency of the suggested protocol.展开更多

Despite a great deal of criticism on the novel Pale Fire the poem Pale Fire within it has been neglected. This essay commits to analyze this poem from four perspectives, namely its symmetrical structure, the counterpoint of the poem, its parody and intertextuality and its meta-poetic element. By doing the detailed examination this essay proves that this 999 line poem embodies the significant themes of this novel, which are the counterpoint and"a Web of Sense".展开更多

Anemia is the most public health problem in school age children. It has a wide range of adverse results involving, poor cognitive performance, poor development of infants, preschool and school-aged children. Anemia also causes the impairment of physical capacity, work performance of adolescents and adults, reduction in immune competence and increased morbidity from infections in all age groups. Our study based on 1686 volunteers was randomly selected from different Government High schools and colleges. A Questionnaire was utilized for data collection. BMI was also calculated by dividing weight in kg by the square of height in meters. Hemoglobin (Hb), Hematocrite (Hct), Mean Corpuscular volume (MCV), Mean Corpuscular hemoglobin concentration (MCHC), white blood cell (WBC) and red blood cell was examined using Sysmex kx-21N hemoglobin auto analyzer (Hedwin, 2008). The total percentage of anaemic students (43.1%) and non-anaemic (56.9%) were observed in district Shaheed Benazirabad. The mean Hb level of anaemic students (11.1 ± 4.94) was observed. In males (12.7%) and females (30.4%) anemic was observed. The prevalence of anemia high (16.2%) was observed in the age of 14 - 16 years. The majority of anemic patients (30.2%) belonged to low income group. Area wise prevalence, in rural areas 27.8% and urban areas 15.3% volunteers anaemic was observed. Taluka wise occurrence of anaemia in taluka Sakrand was (14.6%), in taluka Kazi Ahmed (15.0%), in taluka Daur (8.0%) and in taluka Nawabshah was (5.5%). Clinically signs and symptoms showed, pale skin 57.7% and weakness 42.3% were observed in school children.展开更多

The geotemperature of the Turpan\|Hami Basin has the character that suggests higher temperature in the past, in the east and south of the basin, and in the areas of large\|fracture, and lower temperature in the present day and in the west and north of the basin. This feature is controlled by the difference of burial depth of basement and heat flow values, which made Permian source rock mature in the late Triassic and Jurassic source rock mature at the end of Jurassic and the early Tertiary.展开更多
