Present study deals with the structure and development of conducting elements in the nine orders of acrocarpous mosses. The significance of conducting tissues in mosses in relation to their habitat conditions, growth forms and leaf cell patterns has been discussed. Features of cells in different portions of the stem and the laminal cell patterns and costa are taken into consideration. Although water-conducting cells are unspecialized in mosses, yet the study shows that they seem to play a vital role in the conduction and provide additional criteria for the distinction of taxa. Four categories have been determined as (i) Acrocarpous mosses with a distinct thick-walled conducting strand (6-7 layered) as hydrome which is surrounded by patches of leptoids. Cortex consists of thick walled cells (6-10 layered). Costa has stereidal cells and well developed conducting elements in leaf, example Polytrichum (ii) Acrocarps with thick-walled, narrow, elongated conducting strand (4-5 layered), cells angular in the cortex (6-8 layered). Leaf cells are rectangular, irregular and porous with incrassate walls, example Dicranum (iii) Acrocarps with conducting tissue (2-5 layered) stereidal, thick walled or thin walled varying in the course of development. Leaf cells are mutipapillate, rounded-quadrate, costa is present, examples Hyophila, Philonotis and (iv) Epiphytic pleurocarps with conducting cells rudimentary, thickened, scattered (2-4 layers) and parenchymatous, cortical cells (2-3 layered) thick walled. Leaf cells are small, rounded or linear and papillate, costa may be present or absent, example Leucodon. The study would constitute a formidable task, especially if intraspecific structural variability is considered. It serves a model system in the eco-physiological aspects.Keywords

Numerous studies have shown a close relationship between the tribal ecosystem and their nutritional status. The food consumption pattern and dietary practices of Oraons in our earlier reports showed that there are a wide variety of uncommon foods rich in nutrients available to Oraons in Ranchi districts of Bihar. Hence, it was thought of interest to assess the nutritional status of selected Oraons.- Infinite Integrals Involving Bessel Functions of Imaginary Argument

SCATSAT-1 is the Indian Space Research Organisation’s (ISRO’s) newest Ku-band scatterometer which was launched on 26 September 2016 from ISRO’s space-port Sriharikota on-board the PSLV C35 mission. It is an advanced follow-on of OSCAT, ISRO’s first Scatterometer in space on-board the Oceansat-2 satellite, which ceased to operate in April 2014. OSCAT had been a globally acclaimed sensor during its lifetime. The data from SCATSAT-1 exhibit superior quality, and will not only serve the operational wind and weather prediction community in the years to come, but also hold the promise of securing a place in the long-term climate data records. SCATSAT-1 is a standalone scatterometer mission atop the Indian Mini Satellite (IMS-2) bus. The scatterometer payload is a two-beam, dual-polarized, conically scanning, pencil beam, real-aperture radar which measures near-surface wind vectors over ocean exploiting Bragg scattering resonance at Ku-band. It has been developed in ISRO’s Space Applications Centre, Ahmedabad in less than two and half years to replace OSCAT. Although it inherits the instrument specifications from OSCAT, several enhancements have been made in its hardware as well as in the payload characterization from the purview of miniaturization and performance improvement over OSCAT. This article highlights the hardware improvements, the payload characterization methods devised, and the performance enhancements of SCATSAT-1 over OSCAT. The in-orbit performance of SCATSAT-1 is also discussed.Keywords

Land use/land cover (LULC) plays a pivotal role in maintaining the carbon (C) and nitrogen (N) balance in the ecosystem. It is also important for controlling soil organic carbon (SOC) levels by affecting the quantity and quality of below- and above-ground litter inputs and subsequent decomposition. The aim of the present study was to understand the effect of LULC on the C and N fractions and their stocks in the Eastern Himalayan floodplain. The study was conducted at the Pundibari campus of Uttar Banga Krishi Viswavidyalaya, Cooch Behar, West Bengal, India, hosting four kinds of land uses – agricultural croplands, grasslands, plantation croplands and human-interfered lands. The soils were acidic (pH 5.13–5.68) irrespective of the LULC type and low in bulk density (1.02–1.27 g/cm3). Estimation of several forms of C and N, viz. SOC, total C, available N, ammoniacal N, nitrate N, total N, C stock, N stock, etc., indicated variations in these forms under different LULC types. Significant variations (P < 0.05) were found for SOC and ammoniacal N content in different LULC types. Both mean C and N stocks were found highest in grassland soils (18.91 and 2.64 t ha–1 respectively), followed by plantation croplands (17.24 and 2.41 t ha–1 respectively).Keywords
