Opis:
The investigation of thermal modulation on double-diffusive stationary convection in the presence of an applied magnetic field and internal heating is carried out. A weakly nonlinear stability analysis has been performed using the finite-amplitude Ginzburg-Landau model. This finite amplitude of convection is obtained at the third order of the system. The study considers three different forms of temperature modulations. OPM-out of phase modulation, LBMO-lower boundary modulation, IPM-in phase modulation. The finite-amplitude is a function of amplitude ,Tδ frequency ω and the phase differenceθ . The effects of Tδ and ω on heat/mass transports have been analyzed and depicted graphically. The study shows that heat/mass transports can be controlled effectively by thermal modulation. Further, it is found that the internal Rayleigh number iR enhances heat transfer and reduces the mass transfer in the system.

Opis:
Activity pattern and food habits of Grizzled Giant Squirrel were investigated in Srivilliputhur Grizzled Giant Squirrel Wildlife Sanctuary from December 2011 to March 2012. Focal animal sampling method was used to record the activity pattern and food habits. Sampling was done in three different habitats viz., Private land, Reserve forest and Temple land. Feeding was the dominant activity accounting for 35.4% of the activity period. Bimodal feeding pattern was observed in Squirrels, the observations were made from early morning hours to till (0600-1800) late evening hours. The Squirrels feed upon 23 plant species; among them 11 were trees species, 10 climbers and 2 shrubs. Seven types of plant parts were used by Squirrels. Leaf consumption was high (38%) followed by fruit (24%). The high consumption of leaves was due to easy availability of leaves and limited availability of other plant parts. Squirrel‟s invasion into Private Land and Temple Land was observed which can be attributed to abundance and easy availability of food plants, canopy continuity and less predatory pressure.

Opis:
We studied the population records of House Sparrow Passer domesticus 16th to 20th December 2011 during winter in Ramakrishna Beach Road Vishakhapatnam town, Andhra Pradesh. The ecological density of House Sparrow was investigated using fixed width transects. A total of 189 House sparrows were recorded. The present study shows that a notable population of House Sparrow in Beach Road.

Opis:
Acrocarpus fraxinifolius portrait one among the mainstay of agro forestry in Asian tropics. The lofty tree fortified a substantial impact in every horizon of life. The evergreen, deciduous tree of Fabaceae family stands tall about 30-60 m endowed with unique properties which idiosyncrasies it in the plant kingdom. Surpassing the adverse climatic conditions, A. fraxinifolius serves as a shade tree for tea and coffee plantation and epitomises as a multipurpose avenue tree culminating to the culture of agro forestry. Mundani in bloom is a spectacular appearance bestowed with scarlet crimson red flowers attracting infinite migratory birds and insects. The ancestral gene with indelible memory gravitate this extraordinary majestic tree to aestivate and adapt to strongest survive.

Opis:
For the manufacturing of load-bearing carbon fibre reinforced plastics (CFRP) made from staple carbon fibres (CF) , statements of the CF fibre length in the composite are essential. However, no suitable fibre length measuring method is currently available for long staple CF over 60 mm. The aim of this study is the development of an effective method for characterization of the fibre length distribution of long staple CF. For this method, a fibre beard specimen is extracted from a sliver manufactured from 80 mm staple CF, which is then scanned. Greyscale values densities (GD) of the individual length classes are determined from the scanned images, which correspond to the number of fibres per length class. From the proportion of all length classes, a span length diagram and staple fibre length diagram can be compiled. The results show the good potential of the method developed for the fibre length measurement of long staple CF.
Dla wytwarzania kompozytów ze wzmocnieniem włókien węglowych bardzo ważna jest znajomość rozkładu długości tych włókien. Niestety, jak dotychczas nie istniały odpowiednie metody pomiarowe pozwalające charakteryzować włókna odcinkowe o długościach powyżej 60 mm. Celem pracy była analiza istniejących metod pomiarowych oraz opracowanie metody, która umożliwiłaby satysfakcjonujące rozwiązanie tego zagadnienia. Zostały przedstawione zasady działania tej metody oraz uzyskana dokładność pomiarów.

Opis:
$SrBi_2Nb_2O_9$ (SBN) is a bismuth layered perovskite compound, due to its relatively high Curie temperature, has potential application as high ceramic transducer. Also, it is an attractive ferroelectric material that is being considered in non-volatile random access memory cells. Present article describes preparation, dielectric, impedance and modulus characteristics. Temperature and frequency dependence of dielectric permittivity, impedance and electric modulus of barium strontium bismuth niobate ($Ba_{0.1}Sr_{0.9}Bi_2Nb_2O_9$, BSBN) have been studied in the range of 35-590°C and 45 Hz-5 MHz, respectively. The structural analysis of compound revealed orthorhombic at room temperature. Complex impedance Cole-Cole plots are used to interpret the relaxation mechanism. These plots shows the relaxation behavior as non-Debye type. By using the Cole-Cole plots grain and grain boundary contributions towards conductivity have been estimated. From electrical modulus formalism polarization and conductivity relaxation behavior in BSBN have been discussed. DC and AC conductivity measurements have been performed on BSBN.
