The speed of translatory movement of Beggiatoa alba is governed by temperature in such a way that between 5 degrees and 33 degrees the temperature characteristics micro = 16,100 and micro = 8,400 respectively obtain for the temperature ranges 5 degrees to 16.5 degrees and 16.5 degrees to 33 degrees . The "break" at 16 degrees -17 degrees is emphasized by the occurrence of a wider latitude of va...
This paper examined cultural impacts on absolute and relative location estimates of 12 Eastern China cities, based on questionnaires of each city’s latitude and distances between city pairs. Linear regression analysis of the latitude estimates revealed that estimated latitude of a city is significantly related to its actual latitude. MDS analysis of the distance estimates revealed the gap that ...
South Asian populations harbor a high degree of genetic diversity, due in part to demographic history. Two studies on genome-wide variation in Indian populations have shown that most Indian populations show varying degrees of admixture between ancestral north Indian and ancestral south Indian components. As a result of this structure, genetic variation in India appears to follow a geographic cl...
It is widely accepted that modern humans conform to Bergmann's rule, which holds that body size in endothermic species will increase as temperature decreases. However, there are reasons to question the reliability of the findings on which this consensus is based. One of these is that the main studies that have reported that modern humans conform to Bergmann's rule have employed samples that con...
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system with an unknown aetiology. MS has a geographic pattern of prevalence with high prevalence rates between 45 degrees and 65 degrees north. In much of the northern hemisphere, there exists a prevalence gradient, with increasing prevalence from south to north. While genetics may partially explain the latitudinal gradie...
High resolution 21 cm mapping of the Ursa Major Galactic cirrus: power spectra of the high-latitude Hi gas. Abstract. We present a power spectrum analysis of interferometric 21 cm observations of the Ursa Major high-latitude cirrus, obtained with the Dominion Radio Astrophysical Observatory (DRAO) of Penticton (Canada). These high-resolution data reveal the intricate structure of the diffuse Ga...
This paper studies the interannual variability of pollution pathways from northern hemisphere (NH) continents into the Arctic. Using a 15-year model simulation of the dispersion of passive tracers representative of anthropogenic emissions from NH continents, we show that the North Atlantic Oscillation (NAO) exerts a strong control on the pollution transport into the Arctic, particularly in wint...
Global position of the monthly mean Anticyclone (AC) time series, 300 mb aloft in the North-East Indian subcontinent over the range 0-45°N,60-130°E, were identified from the NCEP/ NCAR reanalysis dataset (1958-1998). Seasonal averagelatitude and longitude of the AC centres in the time series show two extreme complementary characters; 10.34°N (min), 102.27°E (max)in March and 29.08°N (max), 86.4...
