This study offers a brief overview of the export and import of wood based panelin India. The statistical parameters such as descriptive analysis, trends, graph and regression analysis have been computed to understand the nature of wood based panels export and import with top 25 countries on the basis of five year assessment, which is accounts 87.7% (1997-1998 to 2001-2002), 89.5% (2002-2003 to 2006-2007) and grow to 91% (2007-2008 to 2011-2012). The result of regression analysis demonstrate high R20.86 in export and 0.97 in import with correlated GDP, FDI and PC-NDP. The wood based panel’s viz. veneers, plywood, fibre boards, particle boards have also been examined for their trends.

One major feature of ambidexterity literature is its focus on how organizational ambidexterity can be achieved for superior organizational outcomes. Extant literature by and large propose that organizational ambidexterity could be attained by adopting one of the two approaches i.e. structural or contextual. By doing so, studies see the organizational structure and organizational context as contradictory factors in achieving organizational ambidexterity, hence adopt a trade-off approach and vacillate the applicability of both structure and context simultaneously. Only few studies, if any, have looked into the organizational structure and organizational context in combination for organizational ambidexterity, leaving an integrated approach unexplored. This study, therefore, addresses such a prevailing gap and proposes that both structural and contextual approaches are complementary in attaining organizational ambidexterity. As a result, this study contributes to elucidating underlying misconceptions and extend the ambidexterity literature by presenting the structurally and contextually integrated approach towards organizational ambidexterity which will serve as a reference for future conceptual and empirical research.

A study was carried out to evaluate the plant architecture of 27 local cassava cultivars (Manihot esculenta Crantz) in the Bengamisa region. The aim was to find out which cultivars could be used as monocultures or in crop associations for better weed control. We used a randomized complete block design with 27 treatments (27 cultivars) repeated four times. These parameters were measured: height of first branch, number of branches and petiole length after three months' planting. The results obtained showed that the 27 cultivars gave three groups of cultivars in relation to the height of the first branching and the number of branches (early, medium and late cultivars). They also showed that there are early cultivars that can be used in monoculture for better weed control (Apolina, Adjele and Atua); medium cultivars that can be used for both cropping systems (pure or associated) and late cultivars, better indicated for crop association.

The conventional solar still is modified by thermal energy storage material (Fly ash particles) to absorb the maximum amount of solar energy during shiny hours to increase the evaporation rate. In this work, fly ash is used effectively to store the thermal energy and also support the still to minimize the heat loss through bottom and side wall of the solar still. The fly ash is effectively used in the solar still to maintain the greater temperature difference between the glass inner surface and water by absorbing the excess amount solar energy during shiny hours. So, evaporation rate increases in the solar still. The quantity of the fly ash in the basin will influence the productivity of the still and other parameters like water temperature‚ glass surface temperature and vapour temperature etc. In this work, the experimental work has been conducted for various quantity of water and various depth of fly ash to find the optimum quantity of water and depth of fly ash in the basin. Finally, the performance of the modified solar still is compared with the conventional solar still under the same climate conditions. The productivity of the modified still is improved by 71 %.

Replantation of hands has become common in various institutions. But, many problems remain in our context especially the quality of the preservation and real-time of replantation, making surgical care more difficult and thus undermines functional proof our patients. We report one case of a young patient presented with a total amputation at the wrist joint of the left hand, despite technical problems in our emergency department, replantation was successfully possible with an acceptable functional and aesthetic result.our patient have recovered a useful function in their replanted hand in daily activities and work. A need of early rehabilitation is stressed and these severe injuries require long periods of rehabilitation; for a good functional recovery, social and professional reintegration of these patients.

New vanillin Schiff bases (A1-A6) have been prepared. The Schiff bases were synthesized via condensation of vanillin with various substituted anilines. Compounds A1-A4 came out as crystals of different colours while A5-A6 were obtained as thick viscous liquid. The organic compounds were characterized by IR spectra, UV/Visible spectra and melting points measurements. Purity of the new compounds was revealed by their sharp melting points. The coordination feasibility of the compounds was tested using compound A1 with Zn2+, Cu2+, Co2+ and Ni2+ salts.

Polyaniline/ poly(o-toluidine) /MMT-clay nanocomposites can be prepared by mechano chemical method in which, interaction of precursor anilinium ion into the clay lattices accomplished by mechanical grinding of Na-MMT in presence of anilinium hydrochloride at room temperature using mortar and a pestle for about 30 minutes and subsequent grinding with oxidizing agent, ammoniumperoxysulphate. The appearance of green colour indicates the formation of polyaniline/ poly (o-toluidine)/ MMT-clay nanocomposites. The morphology and structural characteristics of the polyaniline clay nanocomposites were investigated using FTIR, XRD, Cyclic voltammogram and SEM.

New VO(IV), Mn(II), Co(II) and Ni(II) complexes of the Schiff bases, 2-[(2,3-dihydro-1H-inden-4-ylimino)methyl]-5-nitrophenol (HL1) and 3-[2,4-dihydro-1H-inden-4-ylimino) methyl]napthalen-2-ol (HL2) have been synthesized and characterized by elemental analysis, molar conductance, infrared and electronic spectral measurements. The purity of the ligands is confirmed by microanalyses and 1HNMR. The IR spectra show that the ligands are bidentate coordinating via azomethine N and napthalenol/phenol O atoms, and the metal complexes of HL1 exhibit geometric isomerism being in the Cis-form with a lone vC=N band. The metal complexes all assume a 4-coordinate tetrahedral/square planar geometry with exception of the VO(IV) complex which is 5-coordinate square-pyramidal as corroborated by electronic spectra. None is an electrolyte in nitromethane. The Schiff base, HL2, and its metal complexes have higher molar absorptivities of the ligand bands than HL1 and its metal complexes; due to a closer metal to ligand overlap, a consequence of extended conjugation in the naphthalene ring. The in-vitro antibacterial activities of these complexes and their Schiff bases against Staphylococcus aureus, Bacillus cereus, Escherichia coli, Proteus mirabilis, Klebsiella oxytoca and Pseudomonas aeruginosa shows that HL1 and its metal complexes are more active than HL2 and its metal complexes, and the latter compounds have selective inactivity against Bacillus cereus and Klebsiella oxytoca. It is note worthy that [CoL1]2 exhibited broad-spectrum antibacterial activity like the antibiotic ciprofloxacin (26.0-30.5 mm), although with smaller inhibitory zones in the range 12.5-17.0 mm.

The study was carried out to characterize selected conglomerates of the Banket Series of the Tarkwaian at Tarkwa area and related the textures and mineralogy to gold grade and recovery. The conglomerates contain 60-90% quartz pebbles, with the matrix being fine to medium and rarely composed of coarse-grained quartz. The gold ore also comprises of minor fine-grained ore minerals, sericite, and chlorite. The quartz pebbles were glassy, milky and partially recrystallized into sugary varieties. Primary sedimentary textural characteristics of sub-rounded to rounded pebbles of about 0.5 cm to 3.0 cm diameter are common. The quartz pebbles are moderately sorted and well packed. Gold in the ore ranges from 0.78 - 3.86 g/t such that high-grade ores had glassy quartz pebbles whiles medium to low-grade ores had sugary varieties. Gold recovery (38.66 - 95.08%), generally increased with increase in the percentage of the matrix volume. It is also higher in ore containing grey quartz and containing much ore minerals; lowest recoveries have high quartz, low matrix volume, and richer in quartz. Also, associated with lower recovery was higher chlorite content which may require more metallurgical treatment for efficient recovery.

In this Research paper an attempt has been made to study and determine the position of Middle class of the country in the current taxation system prevailing in the country. Taxation system in India is undergoing revolutionary changes. Tax holds paramount significance in the economy and in the welfare of the country. Tax is an important source of revenue to the government. Every taxpayer is liable to pay a compulsory charge known as tax. The present paper focuses on the tax burden on the middle Income group person especially salaried class. It is a well-known notion that the middle income group mostly consist of salaried class personals who gets a fixed income in their current account so “they have to pay tax” if they are incurring taxable income. Lower class group is mostly exempted from tax liability whereas higher income group especially business class fills low return. The study also reflects tax effect on individual, salaried income personal and on GDP of the country.
