Fuzzy Based Balanced Scorecard for e-Business

The balance scorecard [6] is a performance measurement system that supplements traditional financial measures with the criteria that measures performance from three additional perspectives: customer perspective, internal business perspective, and innovation and learning perspective. In recent years, the balanced scorecard has been applied to information technology in order to ensure that IT is fairly evaluated. The same methodology has also been applied to E-business. Since some of the parameters in the measurement are somewhat inexact, the idea of fuzzy logy can be applied to allow manipulation of both exact and inexact (fuzzy) inputs from the ebusiness to the balanced scorecard. This fuzzy model works with a grade of membership and portrays inexact information represented by fuzzy statements, and explains both fuzzy conditional statements and the inference mechanism. This paper tries to develop a frame -work for Fuzzy-based Balanced Scorecard for Ebusines

EVALUATION OF FROZEN SEMEN BY A CROSOMAL INTEGRITY AND SPERM CONCENTRATION - TWO VITAL QUALITY PARAMETERS OF MALE FERTILITY IN BOVINES

Acrosomal integrity and sperm concentration are two important parameters to assess the quality of frozen semen doses which in terms validates the fertilizing capacity and conception rate. The present study was undertaken to evaluate acrosomal integrity by Giemsa’s stain and sperm concentration of FSS using improved neubauer chamber in Exotic pure Jersey, Crossbred Jersey, Indigenous Gir cattle and Indigenous Murrah buffalo prior to the field use. The overall values of Giemsa’s stain were observed as 73.74±0.31, 18.65±0.33 and 7.79±0.25 percent for Intact Acrosome, Partially Damaged Acrosome and Fully Damaged Acrosome, respectively. Overall values of sperm concentration were 21.98±0.28 million per straw. The study indicated that there was no significant difference (P<0.05) among the breeds and the values mostly correlates with the guideline of Minimum Standard Protocol for Production of bovine semen, 2012 of Govt. of India

Stress causing dynamic changes of four phytohormones in tobacco and tomato: A GC-MS analysis

Many analytical procedures have been developed to determine the importance of phytohormones in different plants. The work reported here provides a sensitive, accurate and readily accessible gas chromatography coupled to mass spectrometry (GC-MS) technique designed for the simultaneous quantitation of phytohormones indole-3-aceticacid (IAA), abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA). These signalling molecules were analysed in two different plants, Tomato and Tobacco grown in vitro. The protocol designed to assess the dynamic changes in endogenous concentrations of hormones to study plant responses to abiotic stresses in leaf tissues. A hormone profiling is obtained from leaves of plants exposed to salt stress show that different plant hormones are involved in diverse physiologicsl processes. Crosstalk between these hormones result in synergetic or antagonic interactions which have important roles to play in abiotic stress response

Loco-regionally advance breast cancer: evaluation of management of breast cancer with special reference to multimodal approach

Background: Breast cancer is one of the most common human neoplasms, accounting for approximately one-quarter of all cancers in females worldwide and 27% of cancers in developed countries with a western lifestyle. The aims of this study were to evaluate the management of loco-regionally advanced carcinoma of breast with special reference to multimodal approach.Methods: The study was conducted on patients with loco-regionally advanced carcinoma of breast, reporting for treatment in a large multi-specialty teaching institute. All patients of stage IIIB were initially treated with neo-adjuvant (induction) chemotherapy (3 cycles), except 4 patients in the study group offered surgery as initial treatment because of small tumor size with limited peu’d orange change in the skin. After this treatment all patients were reassessed with a thorough clinical examination and restaging work upto detect the response of the chemotherapy. All patients who achieved objective response (complete + partial) were offered surgery, followed by CT and RT.Results: About 60% of the patients were in stage IIIB and 32% in stage IIIA. Majority of the tumors were in T4 category (64%). In 28% cases ipsilateral fixed lymph nodes were found. Histopathological examination revealed 76% (38) patients with infiltrating duct carcinoma, 4 patients (8%) had comedo carcinoma, 2 patients (4%) had lobular carcinoma, 2 patients (4%) had medullary carcinoma and 4 patients (8%) had mucinous carcinoma. Both nonresponsive (NR) and disease progression (DP) patients were in stage III B group. About 76.9% patients of stage IIIB (20) achieved partial response. Only 1 patient (33.3%) developed local recurrence after 10 months of completion of treatment. Median disease free survival (DFS) period of this group is 30.2 months. Recurrence rate is stage IIIA patients was 27.7% and in stage IIIB 37.5%. Maximum numbers of disease free patients were found in T3N1 group (85.7%). Patient with N2 and T4 disease chances of recurrence was more than N1 and T3 lesions.Conclusions: Patients with LBAC who are able to complete treatment with chemotherapy, mastectomy, and postmastectomy radiation have a high probability of locoregional control. Neo-adjuvant chemotherapy can make inoperable locally advanced breast cancer operable and with the use of neo-adjuvant CT, breast conservation surgery is possible even in locally advanced breast cancer. Use of post-operative CT and RT can increase the disease free survival period. Use of multimodal treatment in the form of CT, surgery and radiotherapy can increase the disease free survival period in locally advanced breast cancer. The advent of successful multimodal regimens incorporating systemic treatment (chemotherapy or chemohormonal therapy) as well as local therapy (surgery and radiation) has significantly improved disease-free and overall survival as well as local-regional control. Longer follow-up of these conservatively treated patients will be needed, however, to determine whether local-regional control is preserved

Flow visualization of pollutant mixing in freshwater body near the density maximum

Mixing in water bodies forms a major part of the environmental hydraulic studies. In the present study, effects of density variations in freshwater manifested in the form of convection currents on the water quality parameters is studied. Convection forms a dominant mixing mechanism for near-stagnant lakes i.e. with high residence times. However, due to tedious computations involved in simulating natural convection, water quality models available commercially or open-source solve vertically hydrostatic equations which fail to capture the circulation currents. A hydrodynamic model is conceptualized for describing the setting up of vertical circulation currents driven by the buoyancy. 2D incompressible Navier-Stokes, plus equations for transport of scalars (heat and concentration) are formulated and solved. Concentration profile of a conservative parameter is simulated to study the anomaly in temperature-density relationship on mixing.Density is assumed to be a function of temperature only (at 0.1Mpa) and various formulations like linear, quadratic and IAWPS(The International Association for the Properties of Water and Steam)are used in the model. The phenomenon is investigated near 4°C i.e. at the anomalous behavior of temperature-density curve. Impact of this anomaly on the hydrodynamics and subsequently on the mixing of water quality parameter is studied and visualized to facilitate interpretation and use. Modeling and simulation results for the hydrodynamics are validated against reported work

Influence of isochronal annealing on the microstructure and magnetic properties of Cu-free HITPERM Fe40.5Co40.5Nb7B12 alloy

Systematic study of the effect of isochronal annealing on the structure and magnetic properties of Cu-free HITPERM alloy (Fe40.5Co40.5Nb7B12) is described herein. Mo¨ssbauer spectroscopy (MS) and anomalous x-ray diffraction (XRD) measurement at Fe K-edge (7.112 keV) jointly provide clear evidence for the presence of atomically ordered a0-FeCo (B2 structure) phase as a nanocrystalline ferromagnetic phase. Being a short range order probe, Mo¨ssbauer spectroscopy also confirms the development of an additional non-magnetic Nb-rich phase in the nanocrystalline specimens (annealed above 723 K) with simultaneous lowering of the volume fraction of ferromagnetic phases. The fraction of Fe atoms in the non-magnetic phase is rv15% upon annealing at 773 K for 1 h, which increases gradually and reaches to as high as rv19% after annealing at 923 K. This phase was not detected by XRD and transmission electron microscopy (TEM) measurements, which may be attributed to tiny crystallite size and/or high degree of disorder. In the second stage of crystallization, i.e., above 923 K, the alloy becomes fully crystalline and a stable, hard magnetic fcc-(FeCo)23B6 type phase was observed as a main boride phase along with soft magnetic a0-FeCo phase and Nb rich non-magnetic phase. Thermo magnetic measurement evidenced re-crystallization process as a considerable decrease in magnetization at the second transformation stage. Simultaneous lowering of the volume fraction of magnetic phases with the formation of non-magnetic phase provides convincing origin for the decrease in magnetization at the second crystallization stag

Development of genic-SSR markers by deep transcriptome sequencing in pigeonpea [Cajanus cajan (L.) Millspaugh]

<p>Abstract</p> <p>Background</p> <p>Pigeonpea [<it>Cajanus cajan </it>(L.) Millspaugh], one of the most important food legumes of semi-arid tropical and subtropical regions, has limited genomic resources, particularly expressed sequence based (genic) markers. We report a comprehensive set of validated genic simple sequence repeat (SSR) markers using deep transcriptome sequencing, and its application in genetic diversity analysis and mapping.</p> <p>Results</p> <p>In this study, 43,324 transcriptome shotgun assembly unigene contigs were assembled from 1.696 million 454 GS-FLX sequence reads of separate pooled cDNA libraries prepared from leaf, root, stem and immature seed of two pigeonpea varieties, Asha and UPAS 120. A total of 3,771 genic-SSR loci, excluding homopolymeric and compound repeats, were identified; of which 2,877 PCR primer pairs were designed for marker development. Dinucleotide was the most common repeat motif with a frequency of 60.41%, followed by tri- (34.52%), hexa- (2.62%), tetra- (1.67%) and pentanucleotide (0.76%) repeat motifs. Primers were synthesized and tested for 772 of these loci with repeat lengths of ≥18 bp. Of these, 550 markers were validated for consistent amplification in eight diverse pigeonpea varieties; 71 were found to be polymorphic on agarose gel electrophoresis. Genetic diversity analysis was done on 22 pigeonpea varieties and eight wild species using 20 highly polymorphic genic-SSR markers. The number of alleles at these loci ranged from 4-10 and the polymorphism information content values ranged from 0.46 to 0.72. Neighbor-joining dendrogram showed distinct separation of the different groups of pigeonpea cultivars and wild species. Deep transcriptome sequencing of the two parental lines helped <it>in silico </it>identification of polymorphic genic-SSR loci to facilitate the rapid development of an intra-species reference genetic map, a subset of which was validated for expected allelic segregation in the reference mapping population.</p> <p>Conclusion</p> <p>We developed 550 validated genic-SSR markers in pigeonpea using deep transcriptome sequencing. From these, 20 highly polymorphic markers were used to evaluate the genetic relationship among species of the genus <it>Cajanus</it>. A comprehensive set of genic-SSR markers was developed as an important genomic resource for diversity analysis and genetic mapping in pigeonpea.</p

A typhoid fever outbreak in a slum of South Dumdum municipality, West Bengal, India, 2007: Evidence for foodborne and waterborne transmission

<p>Abstract</p> <p>Background</p> <p>In April 2007, a slum of South Dumdum municipality, West Bengal reported an increase in fever cases. We investigated to identify the agent, the source and to propose recommendations.</p> <p>Methods</p> <p>We defined a suspected case of typhoid fever as occurrence of fever for ≥ one week among residents of ward 1 of South Dumdum during February – May 2007. We searched for suspected cases in health care facilities and collected blood specimens. We described the outbreak by time, place and person. We compared probable cases (Widal positive >= 1:80) with neighbourhood-matched controls. We assessed the environment and collected water specimens.</p> <p>Results</p> <p>We identified 103 suspected cases (Attack rate: 74/10,000, highest among 5–14 years old group, no deaths). Salmonella (enterica) Typhi was isolated from one of four blood specimens and 65 of 103 sera were >= 1:80 Widal positive. The outbreak started on 13 February, peaked twice during the last week of March and second week of April and lasted till 27 April. Suspected cases clustered around three public taps. Among 65 probable cases and 65 controls, eating milk products from a sweet shop (Matched odds ratio [MOR]: 6.2, 95% confidence interval [CI]: 2.4–16, population attributable fraction [PAF]: 53%) and drinking piped water (MOR: 7.3, 95% CI: 2.5–21, PAF-52%) were associated with illness. The sweet shop food handler suffered from typhoid in January. The pipelines of intermittent non-chlorinated water supply ran next to an open drain connected with sewerage system and water specimens showed faecal contamination.</p> <p>Conclusion</p> <p>The investigation suggested that an initial foodborne outbreak of typhoid led to the contamination of the water supply resulting in a secondary, waterborne wave. We educated the food handler, repaired the pipelines and ensured chlorination of the water.</p

Strategies for identifying stable lentil cultivars (Lens culinaris Medik) for combating hidden hunger, malnourishment, and climate variability

Iron and zinc malnutrition is a global humanitarian concern that mostly affects newborns, children, and women in low- and middle-income countries where plant-based diets are regularly consumed. This kind of malnutrition has the potential to result in a number of immediate and long-term implications, including stunted growth, an elevated risk of infectious diseases, and poor development, all of which may ultimately cause children to not develop to the fullest extent possible. A determination of the contributions from genotype, environment, and genotype by environment interactions is necessary for the production of nutrient-dense lentil varieties that offer greater availability of iron and zinc with a high level of trait stability. Understanding the genotype and environmental parameters that affect G x E (Genotype x Environment) interactions is essential for plant breeding. We used GGE(Genotype, Genotype x Environment interactions) and AMMI (Additive Main effects and Multiplicative Interaction) models to study genetic stability and GE(Genotype x Environment interactions) for grain Fe, Zn, Al, and anti-nutritional factors like phytic acid content in sixteen commercially produced lentil cultivars over several different six geographical locations across India. Significant genetic variability was evident in the Fe and Zn levels of different genotypes of lentils. The amounts of grain iron, zinc, and phytic acid varied from 114.10 to 49.90 mg/kg, 74.62 to 21.90 mg/kg, and 0.76 to 2.84 g/100g (dw) respectively. The environment and GE (Genotype x Environment interactions) had an impact on the concentration of grain Fe, Zn, and phytic acid (PA). Heritability estimations ranged from low to high (53.18% to 99.48%). The study indicated strong correlation between the contents of Fe and Zn, a strategy for simultaneously increasing Fe and Zn in lentils may be recommended. In addition, our research revealed that the stable and ideal lentil varieties L4076 (Pusa Shivalik) for Fe concentration and L4717 (Pusa Ageti) for Zn content, which have lower phytic acid contents, will not only play an essential role as stable donors in the lentil bio-fortification but will also enable the expansion of the growing area of bio-fortified crops for the security of health and nutrition
