The factors to determine the economic growth of South Asian Association for Regional Cooperation (SAARC) countries are foreign direct investment, total debt, gross domestic investment and inflation. Simple ordinary least square is applied to analyze the determinates of economic growth with the help of panel data for 39 years with annual frequency from 1971 to 2009. The economic growth may gain boost by the factors not only by these but also many others. In this study foreign direct investment and inflation are found having inverse relationship with economic growth while gross domestic investment and total debt are found positively associated with economic growth. This study may prove useful contribution for policy making for South Asian countries.

This untreated domestic wastewater is badly affecting the ecosystem. In the present study, we have tried to develop activated carbon based abatement technique for domestic wastewater. Dalbergia sissoo and Cedrus deodara saw dust was used for the preparation of activated carbons (ACs), using different activating agents (BaCl2, H3PO4, and H2SO4). The efficiency and potential of developed ACs for Color, chemical oxygen demand (COD) and biological oxygen demand (BOD) removal was investigated in batch mode experimentation. Different operating parameters like contact time, COD and BOD load, pH and activated carbon amount were also investigated. Statistical analysis showed that every AC is significantly diverse in their potential for domestic wastewater treatment. Dalbergia sissoo based AC was most proficient; reduced 87% COD, 87% BOD and 93% color. The results of this study can...

Discharge of wastewater (containing heavy metals) without treatment leads to the damage to all functions of ecosystem. The present study is the continuation of previous work. Previously plant based activated carbons were prepared and used for the removal of COD and color and show removal efficiency of 93% and 100%, respectively. In the present study the same activated carbons are used for the removal of Cr(VI) from wastewater. Activated carbons were prepared from saw dust of Dalbergia sissoo, Cedrus deodara and Eucalyptus spp., using H3PO4, H2SO4 and BaCl2 as activating agents. These raw materials are of low cost and exhibit greater efficiency for Cr(VI) removal. Statistical analysis revealed that all the three saw dusts and activating agents differ significantly in their physiochemical parameters. The efficiency o...

This industrial wastewater (IWW) contains number of toxic chemicals, and their entry in natural water streams disturbs the whole ecosystem. Out of many physical and chemical methods for treating IWW, nature based systems are gaining popularity being more eco-friendly, less laboriously and economical. One way is to irrigate forest with IWW and the toxic material will be taken up by plants and is stored for longer time. The present study is based on the same principle and is the part of mega/intensive project. We conducted germination (irrigated with different concentration of IWW) studies on 8 tree species. Only 4 responded well in the following sequence; Dalbergia sissoo L. > Albizia lebbeck (L.) Benth > Bauhinia purpurea L. > Pongamia pinnata (L.) Pierre. Germination %, germination time, seedling length and seedling fre...

In such analysis workflows, cell nuclei segmentation is typically the first step and is followed by cell body segmentation, feature extraction, and subsequent data analysis workflows. Therefore, it is of utmost importance that the first steps of high-content analysis are done accurately in order to guarantee correctness of the final analysis results. In this paper, we present a novel cell nuclei image segmentation framework which exploits robustness of graph cut to obtain initial segmentation for image intensity-based clump splitting method to deliver the accurate overall segmentation. By using quantitative benchmarks and qualitative comparison with real images from high-content screening experiments with complicated multinucleate cells, we show that our method outperforms other state-of-the-art nuclei segmentation methods. Moreover, we provide a modular and easy-to-use implementation of the method for a widely used platform.

ABSTRACT Bioprocess scale-up from optimized flask cultivations to large industrial fermentations ... more ABSTRACT Bioprocess scale-up from optimized flask cultivations to large industrial fermentations carries technical challenges and economical risks. Essentially, the prediction of optimal process conditions in large fermentations based on small scale experiments is non-trivial. For example, common statistical methods encounter problems with the high-dimensional, small sample size and, on the other hand, the use of various scale-up criteria requires a priori knowledge that may be difficult to obtain. We propose a novel computational scale-up approach applicable to various bioprocesses. The method bases on regularized linear and logistic regression. With embedded feature selection, it automatically identifies the most influential parameters and predicts their values in large scale. In addition, the method predicts the resulting large scale yield. As a case study, we examined the production of a cytotoxic compound. We predicted scale-up from flask and 2L to 30L fermentations and found that, in both cases, the product yield predictions are close to experimentally observed yields.
