The study was carried out in one of the districts Nangarhar province located Eastern Afghanistan between latitude 34.25o N and longitude 70.50o E. has huge ground surface water resources. There are 78 irrigation canals having an overall length 365 km. Behsud Canal is district Afghanistan. results showed that highest crop requirements were found for month July Canal. Similarly, application effic...

A very large body of information has been collected on the structure of the Galaxy. Here we can only concentrate on a small selection of the most recent and most important observational facts and theoretical findings. The MILKY WAY GALAXY belongs to the Local Group, a smaller group of three large and over 30 small galaxies, and is the second largest (after the Andromeda Galaxy M31) but perhaps ...

Atlantic bluefin tuna (ABFT) are highly valued and heavily exploited, and critical uncertainties regarding their population structure hinder effective management. Evidence supports the existence of two breeding populations of ABFT; a western population in the Gulf of Mexico and an eastern population in the Mediterranean Sea; both of which migrate and mix in the North Atlantic. Conventional tagg...

The Tibetan Plateau results from the collision of the Indian and Eurasian Plates during the Cenozoic, which produced at least 2,000 km of convergence. Its tectonics is dominated by an eastward extrusion of crustal material that has been explained by models implying either a mechanical decoupling between the crust and the lithosphere, or lithospheric deformation. Discriminating between these end...

Hypoxia in the ocean influences biogeochemical cycling of elements, the distribution of marine species and the economic well being of many coastal countries. Previous delineations of hypoxic environments focus on those in enclosed seas where hypoxia may be exacerbated by anthropogenically induced eutrophication. Permanently hypoxic water masses in the open ocean, referred to as oxygen minimum z...

We present a method to derive positions of molecular clouds along the lines of sight from a quantitative comparison between 2.6mm CO emission lines and 18 cm OH absorption lines, and apply it to the central kiloparsecs of the Milky Way. With some simple but justifiable assumptions, we derive a face-on distribution of the CO brightness and corresponding radial velocity in the Galactic centre wit...

The aim of this study was to classify the most frequently observed atmospheric circulation anomaly patterns in eastern Africa and the adjacent Indian Ocean. As an example of the usefulness of such a classification, the second objective was to test whether these patterns account for intraseasonal rainfall anomalies in the region. A partitioning algorithm, known as dynamical cluster analysis, was...

The response of the equatorial Pacific Ocean’s seasonal cycle to orbital forcing is explored using idealized simulations with a coupled atmosphere–ocean GCM in which eccentricity, obliquity, and the longitude of perihelion are altered while other boundary conditions are maintained at preindustrial levels. The importance of ocean dynamics in the climate response is investigated using additional ...

Previously reported work in Uganda Protectorate included a leprosy survey by samples of the population in a wide range of places (1). The total number of persons examined then was 14,808, and the leprosy prevalence indicated was 54 per thousand; but since the population of Uganda is over 4,000,000 it was emphasized at the time that that survey needed amplifying and extending. In pursuance of th...
