International Migration, Remittances and its Macroeconomic Impact on Indian Economy

This paper tried to study the impact of remittances on various macroeconomic and developmental aspects for the Indian economy. For this, the data regarding remittances and some of the macroeconomic variables like GDP, PFCE, GDFC, savings, FDI, FII, export, import and balance of trade deficit etc have been analyzed for the period 1971-2008. The study shows that remittances have been consistently increasing at very fast rate for the last 15 years which have significant implications on the above mentioned macroeconomic variables. Through this study, the importance of remittances as a source of external development finance has been discussed. At last, some of the regulatory frameworks governing the flow of remittances have also been discussed.

An effective modeling approach for high efficient solar cell using virtual wafer fabrication tools

In order to give a real understanding and realization of all the phenomena occurring inside the photovoltaic cell devices, the development of a reliable simulated model first is also essential. In this paper, a novel method for developing a realistic model of an efficient solar cell is presented. An efficient model of a Dual Junction InGaP/GaAs solar cell having GaAs tunnel diode is prepared and fully simulated using Silvaco VWF/ATLAS code. An optimization of window layer, ARC, BSF etc are also performed incorporating the effect of some of the different parameters on the performance of this model. The major stages of the process are explained and the simulation results are compared with published experimental data to demonstrate the accuracy of our results produced by the model utilizing this technique. For this optimized InGaP/GaAs Dual Junction cell model having 125 nm DLAR on 18 nm InAlP textured window with effective 500 nm InAlGaP bottom BSF , a maximum conversion efficiency of 32.20 % (1 sun) and 36.67 % (1000 suns) is obtained under AM1.5G illumination. The introduction of this modeling technique to the photovoltaic community will prove to be of great importance in aiding in the design and development of advanced solar cells using Silvaco Virtual Wafer Fabrication Tools.

Success of electromagnetic shock wave lithotripter as monotherapy in large renal calculi—Our experience

AbstractObjectivesTo evaluate the success of shock wave lithotripsy (SWL) as monotherapy for solitary renal stones larger than 2cm without ureteral stenting. Hence, if our study result demonstrates acceptable success and safety, we can recommend ESWL as a treatment option for patients with large renal calculi.Subjects and methodsThis is a prospective study conducted in the Department of Urology, Regional Institute of Medical Sciences, Imphal, India, from January 2011 to December 2012. A total of 104 patients aged between 20 and 70 years with solitary large (>2cm) renal stones underwent ESWL using the Dornier Compact Sigma Lithotripter. Stone size was calculated by measuring the largest dimension of the stone in KUB plain films. In each session, 3000–3500 shocks at frequency 60–90min−1 and intensity between 1 and 4 were given. A maximum number of six sessions were given. Successful treatment was defined as complete clearance or residual stones smaller than 4mm on KUB performed 3 months after the first session.ResultsTotal number of patients was 104. The M:F ratio was 1:1.4. The stone size ranged from 21 to 55mm. The overall success rate was 73%. For stones >30mm, the success rate was only 62.2% (n=28). The number of sessions required increased as the stone size increased. The most common complication encountered was haematuria.ConclusionESWL remains the cornerstone of therapy for renal calculi less than 2cm. Our study reveals that multiple sessions were required for solitary renal calculi, with higher rate of ancillary procedures. The success rate of ESWL for both non-staghorn and staghorn calculi with size above 2cm is low, so other treatment modalities like PCNL should be considered as the first treatment option. However, with appropriate patient selection, significant improvements in stone-free rates may be achieved

Computation of Onset and Growth of Delamination in Double Cantilever beam Specimens Subjected to Fatigue Loading

In this article, the delamination onset and growth behavior of double cantilever beam (DCB) specimens has been presented. The modeling of a debonded region using master and slave surface technique for DCB specimens is done in ABAQUS CAE. The analysis of DCB specimens comprising of fatigue cyclic load has been done in ABAQUS. An onset and Paris delamination growth regimes are plotted. The growth regime being linear in log-log scale, the prediction of constants of this regime has been obtained using the polyfit command in the MATLAB environment. To obtain these constants has been explained in this article. Comparison of experimental and analytical results is shown for delamination growth. The strain energy release rate values for threshold and critical are indicated on the graphs. The number of cycles for delamination onset and growth has been tabulated for various load cases.Defence Science Journal, Vol. 64, No. 4, July 2014, pp. 400-405, DOI:http://dx.doi.org/10.14429/dsj.64.4069

Characterization and classification of coconut-growing soils of Maddur, Karnataka and comparative evaluation of their suitability towards tender coconut production

A study was conducted along the coconut-growing soils of Karnataka to assess the potential of soils and consequences towards tender coconut production and marketing system. Major coconut-growing soils across the different agro-climatic zones of Karnataka were investigated for their development by studying the soil profiles. It was observed that the soils are moderately well to well-drained, moderately deep to deep black, gravelly or non-gravelly red loamy and clayey in central, eastern and southern dry, southern transitional and coastal zones, with good water holding capacity and medium to high fertility. Soils in Maddur were characterized and classified in this study. It was found that the soils in Maddur are deep, well-drained, gravelly clayey with low available water capacity on undulating inter-fluves, with moderate erosion, classified to clayey-skeletal, mixed, semi-active, isohyperthermic Typic Rhodustalfs at the family level and found to be ideal for tender coconut cultivation due to better rainfall distribution, suitable temperature, the elevation of the area, rooting conditions, moisture availability to roots, favourable soil reaction, higher base saturation, N, K and B levels along with gravelly clayey sub-soil and gravelly sandy loam surface texture

The maximum particle density (3.01g/cc), water holding capacity (58.23 %) and pore space (63.40 %) were observed in the treatment T3 (C3I3M3), whereas maximum bulk density (1.09 g/cc) was observed in the treatment T1 (C1I1M1). The maximum EC (0.58dS m-1), Organic carbon (0.66 %), available nitrogen (279.76 kg/ha), phosphorous (19.62 kg P2O5/ha) potash (194.90 kg K2O/ha), zinc (0.65 ppm) and sulfur (14.89 ppm) were found in treatment T3 (C3I3M3). The electrical conductivity gradually increased from control (C0I0M0-0.45) to T3 (C3I3M3-0.58) dSm-1 . The maximum dry weight, test weight and yield were found in the treatment T2 (C2I2M2) viz., 154.43, (230.33 and 50.50 qha-1 respectively for alluvial soil

Development of carp fish culture practice under different stocking densities in mid hills of Uttarakhand, India

The present study was undertaken in order to standardise the stocking density values of carps fishes for sustainable fisheries development in mid hills and enhancing the fish production. The paper deals with growth performance of 3 exotic fish species in low stocking density i.e. 3 fish/m3 over high stocking density of 5 fish/m3 and 10 fish/m3 in the control pond. The net production was 12.6% higher with stocking density of 3 fish/m3. Among the both tested density, the combination of 30: 40: 30 was superior (45.6%) in terms of growth and production in comparison to the other combinations and control. In present study, the highest production as 57.13kg/100m2 (5713 kg/ha.) was achieved in the stocking ratio of 30:40:30 with stocking density of 3 fish/m3. It is 4.7% higher of the combination of 40:30:30 and 4% higher than the combination of 30: 30: 40. It is 12.6% higher than the stocking density of 5 fish/m3 and 48.5% higher than the stocking density of 10 fish /m3. The growth pattern reflected the slow growth during the winter months, reflected the direct negative effect of water temperature on the growth. The production level of existing practice of the farmers may be enhanced up to 1.5 times with proper stocking density i.e. 3 fish/m3 and perfect species combination i.e. 30: 40: 30 for silver carp, grass carp and common carp respectively
