A review on Data Mining for Indian Online Retail Industry

Data mining, the technique of extracting hidden information from large databases, is a powerful new technology with great potential to help companies focus on the most important information in their data warehouses. Data mining tools predict future trends and behaviors, allowing businesses to make proactive, knowledge-driven decisions. The Indian retail industry has emerged as one of the most dynamic and fast-paced industries due to the entry of several new players in the Indian Retail Sector. It increases the need of different knowledge extraction tools which can extract usable information form large data sets. In this paper we have discussed the Overview of an Indian retail sector, the previous study related to the retailing industry. Also the study presents the gaps identified in the previous work

Gene HI1472 of <i>Haemophilus influenzae </i>Rd is a novel gene involved in DNA repair

530-535A chimeric plasmid, pJPuvr4, consists of a 16.7 kbp Haemophilus influenzae Rd chromosomal DNA insert at the EcoRI site of vector pJ 1-8. This plasmid complements the UV and gamma ray sensitivity of the mutant strain MBH4.This plasmid carries the wild type allele of gene uvr4 which was localised to a 3.8 kbp DraI fragment, with an internal Eco RI site. Partial sequencing of the gene and its alignment with the published genome sequence of H. influenzae Rd revealed uvr4 to be HI1472. HI1472 is a putatively identified open reading frame (ORF), which has been assigned no function so far. The partial sequence did show nt database match with 3D exon of N cadherin gene of homosepians and moaA gene of H. Inf luenzae. Cadherins are involved in cell adhesion, cell to cell contact and morphogenesis in homosepians and moaA gene codes for molybdenum biosynthesis subunit A. This report implicates HI 1472 of Haemophilus influenzae Rd in DNA repair. Nucleotide sequence obtained for the gene uvr4 was compared with the published sequence of gene HI1472. A wild type strain variation was observed at the 592nd nucleotide position corresponding to a change from aspartic acid to threonine

SPEECH RECOGNITION SYSTEM FOR BLIND PEOPLE USING RASPBERRY PI AND JASPER PLATFORM

Speech recognition applications are becoming more and more practical nowadays. Various interactive speech aware applications are available in the market. But they are usually meant for and executed on the traditional general-purpose computers. Due to the rapid technological advancements, bigger and more complex tasks are being efficiently performed consuming less time and efforts. This can be further simplified with a more hands-free approach with the help of Voice Controlled System. For implementing this, we use an open source platform called Jasper for Raspberry Pi. Our aim is to build an automated personal secretary who could remind us of our schedule and optimize the rudimentary ways of performing tasks at one’s commands

RP-LC gradient elution method for simultaneous determination of thiocolchicoside, aceclofenac and related impurities in tablet formulation

Objective: The aim of the present study is to develop a simple and precise HPLC method for simultaneous determination of thiocolchicoside, aceclofenac and related impurities in a tablet formulation and validate as per ICH guidelines. The aim of study extends to perform forced degradation study to trace the degradation pathways of potential degradant impurities. Materials and Methods: The separation was achieved on a 4.6 mm × 100 mm, 3 μm C 18 column at 40°C with the mobile phase containing 0.1 M ammonium acetate buffer and methanol in a gradient mode at a flow rate of 1.0 mL min−1 . The UV detection was carried out at 257 nm. Results: Acelofenac, thiocolchicoside and their related compounds were well separated from each other with good resolution and symmetry factor without interference of excipients. The method for assay was linear in the range of 10-200 μg mL−1 for aceclofenac and 0.4 to 8 μg mL−1 for thiocolchicoside. Conclusion: The method was validated according to ICH guidelines and the acceptance criteria for accuracy, precision, linearity, specificity, robustness, ruggedness and system suitability were met in all cases. The method was highly specific, as two related compounds of thiocolchicoside and nine related compounds of aceclofenac were well separated from each other. Stress study ensured the specificity of the method as the unknown degradation products formed during stress studies did not interfere with the determination of thiocolchicoside and aceclofenac, thus proving the stability indicating capacity of the method

Evaluation of bioemulsifier production by <i>Comamonas sp. CBJ1 </i> isolated from oil-contaminated soil

1365-1370Comamonas sp. CBJ1 isolated from oil-contaminated soil was evaluated for bioemulsifier production in phosphate buffered mineral salt medium with different carbon substrates, viz. coconut oil, sesame oil and n-hexadecane. Bioemulsifier production in culture broth was assessed using emulsification assay and surface tension analysis. Highest emulsification activity was observed on day 1 in case of coconut oil supplemented broth while in case of sesame oil and n-hexadecane supplemented medium the highest emulsification activity was observed on 2nd and 5th day, respectively. Bioemulsifier produced with coconut oil supplemented medium found effective in emulsification with other substrates. The yield of bioemulsifier produced by Comamonas sp. CBJ1 was more in medium supplemented with coconut oil (1.6 g/L) than that of in sesame oil (1.0g/L) and n-hexadecane (0.31g/L)

Deactivation and Regeneration of Mn-Promoted Sulfated Zirconia Alkane Isomerization Catalysts: An In-Situ Spectroscopic Study

Abstract Mn-promoted sulfated zirconia (0.5 or 2 wt% Mn) was investigated during activation (in inert or oxidizing atmosphere at 703–773 K), during n-butane isomerization (323–333 K, 1 kPa n-butane) and during regeneration (see activation conditions) using in situ UV–vis–NIR, diffuse reflectance IR, and X-ray absorption spectroscopies. While the activation atmosphere did not influence the degree of hydration and the state of the sulfate, manganese—which was always present as a mixture of Mn2+ and higher oxidation states—was slightly reduced in the absence of oxygen. Catalytic data did not give a clear picture as to whether activation in oxygen-containing atmosphere is advantageous or not. The catalysts deactivated within hours, but complete recovery in O2 was possible. Heating of a deactivated catalyst in N2 produced an inactive material and unsaturated compounds on the surface
