An area in the Middle Ganga Basin, lying around Monghyr, Bihar, has been selected for delineation of fluvial palaeofeatures. The investigation is based on aerial photographs LANDSAT MSS and TM data products and ground data. Digital enhancement of LANDSAT MSS and TM data by linear contrast stretching and ratioing has been found to be highly powerful in identification and mapping of subtle fluvial palaeofeatures. Based on the above interpretation, a summary of the fluvial palaeo-history is presented.Keywords

Liquefaction in saturated sandy soils as a result of earthquake-induced shaking, poses a major threat to men and materials. Many parts of the Indo-Gangetic plains have experienced such catastrophes repeatedly. The border region of southern Nepal-northern Bihar (India) is a typical existing setting prone to soil liquefaction in the Indo-Gangetic Plains. The Bihar-Nepal earthquake of 1934 (Ms>8) and the earthquake of 1988 (Mb = 6.7) induced extensive liquefaction in the terrain in living memory. Characteristics of soil in this area of nothern Bihar have been determined from field samples. Various parameters (e.g. clay content, D50 - and C-values) indicate high susceptibility to liquefaction among soils in the area.
A close study of remote sensing data (Landsat TM and MSS) products reveals that the boundaries of liquefaction zone in the Bihar-Nepal region during the 1934 earthquake are identifiable on the remote sensing images. This is due to a combination of several inter-related factors, such as landform, soil type, soil moisture and vegetation. These clues have been applied as guides on the adjoining remote sensing images for delineating areas on a regional scale, where liquefaction might possibly occur in the Ganga plains, in the event of future Himalayan earthquakes.

Study of aquifer geometry is essential for proper development and utilization of groundwater resources. In this study, a systematic approach has been made in the analysis of shallow aquifer geometry in the western Ganga Plains, Uttar Pradesh, by integrating the well-Log and remote sensing data. The study includes mapping of neotectonic lineaments from remote sensing data, and determination of aquifer depth and lithological details from the well-Log data. The well-Log data indicate that the region has varying thickness of alluvium composed of alternating sand, kankar and clay strata. By integrating the remote sensing and well-Log data sets, sub-Surface geological sections have been developed to interpret the aquifer geometry. The aquifers are found to show significant variation in nature and geometry from place to place. At some places, the lineaments on remote sensing images are in conformity with faults interpreted from well-Log data, whereas at others, buried faults have been interpreted. The aquifers formed by paleochannels is particularly striking, being unconfined in nature and mainly consisting of medium to coarse sand, along with pebbles, cobbles and kankar.Keywords

This article presents results on surface ice velocity of the Chhota-Shigri glacier, Himachal Himalaya, deduced by applying sub-pixel image correlation technique (COSI-Corr software) on the ASTER time series data (2003-2009). The remote sensing-derived measurements are found to match quite well with the field measurements. In general, the surface ice velocity varies from ∼20 m/yr to ∼40 m/yr. Velocity variations occur in different parts of the glacier and also from year to year. In all the years considered for this glacier, the mid-ablation zone and the accumulation zone exhibit higher velocities and zones near the snout and equilibrium line altitude have relatively lower velocities. Further, the velocities are found to be relatively higher in the years 2005-2006 and 2007-2008 and lower in the years 2006-2007 and 2008-2009. These spatial and temporal variations in velocity, which could be related to the glacier morphology and hydro-metrological factors, need to be further studied.Keywords

It is generally believed that the Moon became inter-nally dead ∼1 b.y. from the present, and only old ( 1 b.y.) volcanic flows forming largely the mare basins are known to occur. The old volcanic land-forms stand largely obliterated and flows studded with impact craters. However, recent findings have indicated global presence of young thrust faults on the Moon, escape of gases from the interior and also pre-dicted the presence of partially molten lower lunar mantle and core. Here, we have used high-resolution datasets from NASA's LRO, Kaguya of JAXA and ISRO's Chandrayan-1 missions to examine the char-acteristics and origin of multiple relatively fresh, coaxial, superposed viscous flows spotted inside the Lowell crater on the far side of the Moon. Various considerations apparently rule out the possibility of these melts being derived from nearby areas. An asso-ciated likely source crater and tectonic structures (a fault and a fracture) of two different ages but emanat-ing from the same crater and affecting different flows have also been located - exhibiting tectono-volcanic relationship. These features provide evidences of like-ly volcanic activity in the region not too far in the past, are consistent with recent results that the Moon may not be internally dead, and thus have implica-tions to the thermal history and present-day geologic nature of the Moon.Keywords

In the Himalayas, snowmelt runoff makes a dominant contribution to the total annllal stream flow. An early prediction of the amount of runoff to be derived from the snow pack is, therefore, of great importance for proper management of water resources. The area selected for the present investigation is the Punjab Himalayas comprising three major catchments of the Beas, Ravi, and Chenab rivers. Landsat imageries have been used to map snow cover in these three catchments. Data from a number of discharge gauging stations on the Beas, Ravi and Chenab rivers have been used to yield snowmelt runoff. Unique relationships between satellite snow cover and snowmelt runoff have been obtained for each of the sub-catchments. The studies show that geomorphometric parameters have a systematic influence on the relationship between snow cover area and subsequent runoff. The relationships are interpreted for their physical implications.Keywords

Zinc deficiency, encountered throughout the world in man and domestic animals adversely affects the nucleic acid and protein metabolism; thereby affecting the growth promoting ability of dietary protein. Protein efficiency ratio (PER) which is the most common method used for evaluation of protein quality has been reported to be influenced by a number of nutritional factors. However, little attention has been given with respect to zinc deficiency.- Effect of Experimental Phosphorus Deficiency on Protein and Feed Efficiency Ratios in Rats

For the last few years efforts are being made to find out the possible application of Single Cell Protein (SCP) as solution to the world wide problem of protein deficiency. The SCP may be used as food for direct human consumption or as animal feed stuff. Various combinations of waste materials (bagasse and straws) and fungi have been tried to get SCP of acceptable nature.- Field Efficacy of New Generation Insecticides for the Management of Spotted Pod Borer, Maruca vitrata(Fab.) in Cowpea

The spotted pod borer, Maruca vitrata(Fab.) causes significant damage by attacking pods in cowpea. The aim of this study was to evaluate the field efficacy of new generation insecticides against spotted pod borer. Field experiments were conducted at Regional Research Station, Nasik (Maharashtra) on cowpea during Kharif,2009 and 2010. Among the new generations tested, flubendiamide 20 WG @ 1.0 g/l (4.79%) was observed significantly higher, in reducing the damage caused by the spotted pod borer in cowpea, on number basis followed by indoxacarb 14.5SC @ 0.5 ml/l (7.99%) and spinosad 45 SC @ 0.3 ml/l (8.70%). The highest marketable yield (91.49 q/ha) was recorded in flubendiamide 20 WG @ 1.0 g/l followed by spinosad 45 SC @ 0.3 ml/l (91.39 q/ha). However, the maximum cost benefit ratio (1:3.2) was recorded in thiodicarb 75 WP @ 1 g/l followed by indoxacarb 14.5 SC @ 0.5 ml/l (1:2.3), spinosad 45 SC @ 0.3 ml/l (1:1.9), emamectin benzoate 5 SG @ 0.5 g/l (1:1.3), flubendiamide 20 WG @ 1.0 g/l (1:1.1). On the basis of efficacy, flubendiamide 20 WG @ 1.0 g/l was observed to be very effective against Maruca vitratain cowpea followed by indoxacarb 14.5 SC @ 0.5 ml/l and spinosad 45 SC @ 0.3 ml/l.Keywords
