In order to perform true bicoordinate navigation, migratory birds need to be able to determine geographic latitude and longitude. The determination of latitude is relatively easy from either stellar or magnetic cues [1-3], but the determination of longitude seems challenging [4, 5]. It has therefore been suggested that migrating birds are unable to perform bicoordinate navigation and that they ...

Currently, most operational forecasting models use latitude–longitude grids, whose convergence of meridians toward the poles limits parallel scaling. Quasi-uniform grids might avoid this limitation. Thuburn et al. and Ringler et al. have developed a method for arbitrarily structured, orthogonal C grids called TRiSK, which has many of the desirable properties of the C grid on latitude–longitude ...

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...

The effect of time of administration of exogenous melatonin (M) at the rate of 100 microg/Kg BW of rat/day for 14 days on immunomodulation to killed Pasteurella multocida (P52 strain) vaccine (KPMV) was investigated in male albino rats during spring season with photoperiod of LL 13: DD 11 h and 25 +/- 2.5 degrees C air temperature and 70 +/- 4% relative humidity. The experiment was conducted at...

The causes of natural variation in alkalinity in the North Pacific surface ocean need to be investigated to understand the carbon cycle and to improve predictive algorithms. We used GLODAPv2 to test hypotheses on the causes of three longitudinal phenomena in Alk*, a tracer of calcium carbonate cycling. Thesephenomenaare (a)an increase fromeast towestbetween45°Nand55°N, (b) an increase fromwest ...

OSSE has measured the galactic longitude distribution of both the 511 keV annihilation line radiation and the three-photon positronium continuum within 40 of the center. They have similar shapes, with a composite longitude distribution well represented by an 11 FWHM Gaussian central bulge together with a possible broad disk component comprising as much as 15% of the integral ux between 40 and 3...

This paper considers a longitude distribution of sunspot groups over 1982–2013, using data from the National Geophysical Data Center (Boulder, USA). The space-time distribution of sunspot groups is analyzed in coordinate sectors calculated from heliographic longitudes of the groups. A longitude extent of a coordinate sector is compared to the average size of one active region (30–40°). Then, in...

General.?Barwadih, a railway settlement on the Gomoh-Sone East Bank branch of East Indian Railway, is 18 miles south-west of Daltonganj. It is situated 348 miles west of Calcutta in the hilly tracts of the Ranclii plateau in the Palamau district of Bihar province. The range of hills to the south of the colony is a branch of the Vindhyas. Physical geography and meteorological data. ?Latitude 23....
