Trust Model for Optimized Cloud Services

Cloud computing with its inherent advantages draws attention for business critical applications, but concurrently expects high level of trust in cloud service providers. Reputation-based trust is emerging as a good choice to model trust of cloud service providers based on available evidence. Many existing reputation based systems either ignore or give less importance to uncertainty linked with the evidence. In this paper, we propose an uncertainty model and define our approach to compute opinion for cloud service providers. Using subjective logic operators along with the computed opinion values, we propose mechanisms to calculate the reputation of cloud service providers. We evaluate and compare our proposed model with existing reputation models

Effect of intravenous clonidine premedication in patients undergoing laparoscopic cholecystectomy

Background: Pneumoperitoneum to facilitate laparoscopic surgery produces hemodynamic changes that can be harmful for the elderly as well as patients with cardiovascular compromise. Clonidine is an alpha- 2 agonist that can attenuate these changes.Methods: This study of 100 patients was a single blind prospective randomized controlled study. Patients were randomly divided into two groups of 50 each. The clonidine group received 2 microgm/kg iv clonidine in 10 ml normal saline 15 minutes prior to induction. The placebo group received only normal saline. Hemodynamic parameters and incidence of vomiting and shivering were noted.Results: Data was analysed by Pearson’s chi-square test. Clonidine significantly attenuated the rise in heart rate, and the blood pressure. The incidence of postoperative nausea and vomiting was less in the clonidine group. It also reduced shivering.Conclusions: 2 microgm/kg of clonidine iv can be reasonably recommended as a premedicant for laparoscopic procedures in otherwise healthy patients. However further study is required to test its efficacy in patients with compromised cardiovascular function

New Chromogenic Spray Reagent for TLC Detection and Identification of Organophosphrous Insecticide Monocrotophos in Biological Material.

Monocrotophos is a member of Organophosphate insecticide. It is an important insecticide and has a diversified role in agriculture in INDIA. The increasing numbers of human poisoning cases were found to be occurred by the consumption of organophosphate insecticide monocrotophos. So in this paper, we represent a novel Thin Layer Chromatographic spray reagent for the detection and identification of Monocrotophos

Valsalva retinopathy in pregnancy: an obstetric dilemma

Valsalva retinopathy is a unilateral or bilateral condition that occurs when increased intra-thoracic or intra-abdominal pressure transmitted to the eye causes a sharp rise in the intraocular venous pressure, and rupture of superficial retinal capillaries. Pregnancy is known to be a risk factor for Valsalva retinopathy. A 29-year-old G2A1 at 38 weeks of gestation previously normotensive presented with unilateral sudden decrease in vision of 1-day duration. Fundoscopy revealed pre-retinal and vitreous hemorrhage of right eye. A diagnosis of Valsalva retinopathy of pregnancy was made after excluding other probable causes for hemorrhage. She had an elective cesarean section with no further deterioration of vision or recurrence of hemorrhage

Size-distribution of submicron aerosol particles over the Indian Ocean during IFP-99 of INDOEX

Measurements of the size-distribution of submicron aerosol particles of diameter from 0.003 to 1 μm are made over the Indian Ocean during the IFP-99 of the Indian Ocean Experiment (INDOEX). Measurements are made during the onward journey from Goa to Port Louis, Mauritius from 20 January to 11 February 1999 onboard ORV Sagar Kanya and during the return journey from Port Louis to Male from 22 February to 1 March 1999 onboard Ronald H. Brown. Observations show large concentrations in the range of 2-6 × 103 particles/cm3 over the Indian Ocean in the northern hemisphere and these drop down to about 500 particles/cm3 in the southern hemisphere. However, the aerosol concentrations show a peak of about 3 × 103 particles/cm3 at 13°S. In the northern hemisphere, the concentration of particles of diameter < 0.0749 μm increases from 14°N to 1°N and then steeply falls. On the other hand, the concentration of particles of diameter > 0.0749 μm keeps decreasing up to 6°S. Size distributions of particles at open sea in the northern hemisphere show a maximum at 0.133 μm and minimum at 0.0422 μm and are generally openended at the smaller size end. The size-distributions of particles are sometimes relatively flat from 0.0133 to 0.237 μm when the particle concentrations are low in the southern hemisphere. The transport and accumulation of aerosol particles in the Inter-Tropical Convergence Zone is discussed. The relative abundance of large versus small particles is examined with respect to the variation of surface atmospheric pressure along the route

Fisheries geographical information system for Greater Mumbai region in Maharashtra, India

Geographical information system (GIS) is an invaluable decision support tool, designed to address spatially related problems for management of natural resources. The power of GIS lies in its ability to visualise and relate various types of geo-referenced spatial and non-spatial data allowing users to analyse them. In India, use of GIS in fisheries management is yet to find its rightful place. An effort has been made in the present study to design and organise a fisheries spatial information system for Greater Mumbai region in Maharashtra to serve as a macro-level database for the planners and administrators, which can be used for querying, analysing and displaying datasets in the form of graphs and summarised tabular data for all the fisheries infrastructural facilities. This GIS will be of immense help to planners, managers and administrators in quick storing, retrieving and updating the required information for management of fisheries in Greater Mumbai region

Effect of annealing on the phase transition in poly (vinylidene fluoride) films prepared using polar solvent

The γ -phase poly (vinylidene fluoride) (PVDF) films are usually prepared using dimethyl sulfoxide (DMSO) solvent, regardless of preparation temperature. Here we report the crystallization of both α and γ -phase PVDF films by varying preparation temperature using DMSO solvent. The γ -phase PVDF films were annealed at 70, 90, 110, 130 and 160°C for five hours. The changes in the phase contents in the PVDF at different annealing conditions have been described. When thin films were annealed at 90°C for 5 h, maximum percentage of β -phase appears in PVDF thin films. The γ -phase PVDF films completely converted to α -phase when they were annealed at 160°C for 5 h. From X-ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), differential scanning calorimetry (DSC) and Raman studies, it is confirmed that the PVDF thin films, cast from solution and annealed at 90°C for 5 h, have maximum percentage of β -phase. The β -phase PVDF shows a remnant polarization of 4.9 µC/cm2 at 1400 kV/cm at 1 Hz
