Testing the consistency between cosmological measurements of distance and age

We present a model independent method to test the consistency between cosmological measurements of distance and age, assuming the distance duality relation. We use type Ia supernovae, baryon acoustic oscillations, and observational Hubble data, to reconstruct the luminosity distance D_L(z), the angle averaged distance D_V(z) and the Hubble rate H(z), using Gaussian processes regression technique. We obtain estimate of the distance duality relation in the redshift range 0.1<z<0.73 and we find no evidence for inconsistency between the data sets used.Comment: 5 pages, 1 pdf figure, minor revision, accepted for publication in Physics Letters

Challenges and Opportunities for Modern Management Education

oai:ojs2.jconsortium.com:article/428Nevertheless, the purpose of management education is to prepare scholars for facing the profligacy challenges of the modern industry and catering to the modern complexities of the projects. The faculty of Management Studies in global academic institutions are required to move towards the modern practices backed with the traditional ways of teaching and learning. These faculties are expected not only to equip themselves with competence of modern technologies but also be innovative in finding solutions to enhance the knowledge, skills, and competence of the scholar community and raise their confidence to face the modern challenges

DEVELOPMENT OF POLYHERBAL WITH ANTIOXIDANT ACTIVITY

Objective: The objective of this research was to develop a polyherbal formulation (PHF) using four different herbs and to evaluate their phytochemicals, physical constants, and determination of their antioxidant activity by DPPH method.Methods: The PHF authenticated herbs were characterized by studying its morphological and pharmacognostic characters. Phytochemical screening showed the presence of alkaloids, glycosides, carbohydrates, amino acid, tannin, steroids, and flavonoids in the combination extract. Physical parameters such as loss on drying (LOD), pH, ash values, LOD, and extractive value have been studied. The antioxidant activity of the combination of extract (100 mg each) was determined using DPPH free radical scavenging method.Results: The results showed that the combination extract has best antioxidant effect at a dose of 400 μg/ml when it was compared with ascorbic acid as the reference standard.Conclusion: The results obtained in this research work clearly showed that the combination extract has best antioxidant effect at a dose of 400 μg/ ml when it was compared with ascorbic acid as the reference standard.Â

Listen to Customer Cries, Before the Software dies

The software marketplace is in a constant state of change with new and disruptive markets emerging while some traditional markets fall by the side. The software development market is also characterized by an irrevocable trend towards greater software complexity -- complexities that not only complicate the community of software developers but also create financial pressures on them as well as their customers. Software technology is changing at such a high rate that software bought this morning gets outdated by next evening. In such a scenario, many a times consumer of the product suffers for paying for an older software unknowingly. It suffers with the system when developer organization of such old systems stops providing technical supports on them stating that newer versions are available in the market to solve their problems and hence the customer should discard the system and purchase a new one. In this paper, the author proposes that software has finite lifetime regardless of its type and development platforms and it must be dismantled before it dies. The process of dismantling the software is treated as its retirement. Author brings into light the current poor scenario of software retirements and desires of consumer community in favor of code of ethics for software developing organizations

STUDY OF ANTIOBESITY ACTIVITY OF POLYHERBAL FORMULATION IN CORRELATION WITH ANTIDIABETIC ACTIVITY

Objective: The objective of this research was to develop a polyherbal formulation using four different herbs using obese diabetic rat's model. Methods: Rats received high-fat diet and alloxan was injected intraperitoneal to rats for induction of diabetes. In the preventive experiment, diabetic rats received Momordica charantia Linn. (200 and 400 mg/kg/day p.o), Eugenia jambolana Linn. (200 and 400 mg/kg/day p.o), Ziziphus mauritiana (200 and 400 mg/kg/day p.o), Acacia catechu (AC) (200 and 400 mg/kg/day p.o), and aqueous extract of all extracts (100 and 200 mg/kg/day p.o). Diabetic rats were also treated with glibenclamide (5 mg/kg p.o.) and orlistat (60 mg/kg/day p.o.) as reference standards. Results: The results showed that the extract of M. charantia Linn., E. jambolana Linn., Z. mauritiana, and AC significantly (p&lt;0.05) inhibited body weight gain, blood glucose, triglyceride, total cholesterol, low-density lipoprotein (LDL), very LDL, high-density lipoprotein cholesterol, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, and fasting blood glucose in a dose-dependent manner. Extracts treated rats at doses of 200 and 400 mg/kg improved dyslipidemia in high-fat diet (HFD)-induced obese rats by enhancing their lipid metabolism when compared to the HFD control. Conclusion: The results obtained in this research work clearly showed that taken together the extract of M. charantia Linn., E. jambolana Linn., Z. mauritiana Lam. AC Willd., and aqueous extract of all extracts has potential as a preventive agent for type 2 diabetes mellitus (and possibly obesity) and deserves clinical trial in the near future
