The Contemporary Affirmation of Taxonomy and Recent Literature on Workflow Scheduling and Management in Cloud Computing

The Cloud computing systemspreferred over the traditional forms of computing such as grid computing, utility computing, autonomic computing is attributed forits ease of access to computing, for its QoS preferences, SLA2019;s conformity, security and performance offered with minimal supervision. A cloud workflow schedule when designed efficiently achieves optimalre source sage, balance of workloads, deadline specific execution, cost control according to budget specifications, efficient consumption of energy etc. to meet the performance requirements of today2019; svast scientific and business requirements. The businesses requirements under recent technologies like pervasive computing are motivating the technology of cloud computing for further advancements. In this paper we discuss some of the important literature published on cloud workflow scheduling

Mechanical characterization and fractography of 100 micron sized silicon carbide particles reinforced Al6061 alloy composites

In the current exploration, the impact of the 100 to 125 micron size addition of silicon carbide (SiC) on the mechanical performance of Al6061 alloy has been studied. The Al6061 alloy dispersed with 6, 9, and 12 wt.% of SiC particles were synthesized by a two-step stir cast route. Two-step addition of the preheated particles into the melt helps avoid the agglomeration of the particles, which further contributes to enhancing the properties of composites. The orchestrated composites were exposed to microstructural examines and mechanical properties evaluation. Microstructural portrayals of acquired examples were completed by SEM microscopy, EDS, and XRD patterns. The event of SiC particles were affirmed by the XRD patterns. The density of the Al6061-SiC composites was increased with the addition of high-density silicon carbide particles. The hardness, ultimate, and yield qualities of metal composites have been improved with the increase in the content of SiC support. The ductility of SiC reinforced composites decreased with hard ceramic particles' incorporation in the Al matrix alloy. Various fracture mechanisms were observed in the Al6061-SiC composites using SEM

Pneumonitis following diesel fuel siphonage

AbstractPetroleum diesel is a complex mixture of liquid hydrocarbons and mainly used as fuel in transport vehicles. The practice of manual siphoning of diesel from fuel tanks is common in developing countries but hydrocarbon pneumonitis due to diesel siphonage is rarely reported. We report pneumonitis following diesel fuel siphonage in a 30-year-old driver. Initially patient had severe nausea and vomiting followed by chest pain and breathlessness after three days. In our case, induced sputum was diagnostic as against majority of cases where bronchoscopy was used as diagnostic tool. Recovery was complete with medical treatment

A New Approach for SAR Image Denoising

In synthetic aperture radar (SAR)  imaging, the transmitted pulses from space born antenna interacts with ground objects and returned energy or back scattered energy will be collected  to get backscattered image. In this process, a speckle noise will be added because of the coherent imaging system and  makes the study of SAR images very difficult. For better SAR image processing, the speckle has to be removed in the initial stages of processing  and maintain all texture features efficiently. The BM3D method is generally considered as state of art method in denoising of SAR images. In this paper, it is proposed a technique to despeckle the speckle noise to the maximum extent while maintaining the edge characteristics

Fishing fathers, vending mothers and educated youth (A maritime community on east coast of India in transition)

In Indian social research, village is considered as one of the units for understanding networks of socio-cultural and economic organization. Such studies are paramount in conceptualizing the social processes such as sanscritization, dominant caste (Srinivas 1955), caste hierarchies (Dube 1960, Dumont and Pocock 1957), jajmani system (Wiser 1969), etc., in Indian context. The Census of India in its survey operations of 1950-51 periods had produced a few monographs on village ethnographies emphasizing the socio-economic and cultural mosaic. Of late, these village studies are contextualized in evaluating the change and continuity of the village profile. Among such monographs, Mufuzbandar a fishermen village in Srikakulam district on the coast of Bay of Bengal has been used as benchmark for the present study to assess the status of fishermen

Economic and domestic activities of maritime fisher women of north coastal andhra pradesh, east coast of India

In anthropological literature, the early studies, particularly of late nineteenth century anthropologists had recorded women’s participation in all aspects of social, economic, political and religious aspects as they were but not emphasizing or focusing distinctly on women. In the present study the analyzed data are presented under three broad heads, such as 1. Procurement and Transport. 2. Sale of fish (wet) and 3. Dry fish and Sale. Each head is further sub headed according to the information pertaining to type of marketing or vending methods and locations. Fisher women activities at domestic level besides the economic are dealt in detail to draw the domestic and entrepreneurial tenacities

Structural, Morphological and 1/f noise Properties of ITO/TiO2 thin Films by e-beam Evaporation System for Optoelectronic Device Applications

In the present research study, ITO/TiO2 thin films were prepared on a glass substrate by using an electron beam (e-beam) evaporation system at different annealing temperatures (300, 350, 400 and 450 °C). The amorphous and crystalline natures of ITO/TiO2 structure were analyzed by X-ray diffraction study. As the grain size becomes larger, indirectly it will develop the crystalline quality of the TiO2 films studied from AFM. The surface of TiO2 films and the crystalline size of the sample were increased gradually with respect to a temperature that is observed in SEM. The elemental composition determined by the energy dispersive analysis of EDAX showed that TiO2 thin films were highly stoichiometric. Further, the higher optical transmittance (93%) was obtained with 450 °C annealed ITO/TiO2 film. The optical band gap increased along with annealing temperatures (300, 350, 400 and 450 °C). All the above results of this present work can be utilized for solar cell and optoelectronic device applications. © 2020 Author(s)

ANTIOXIDANT AND ANTIPROLIFERATIVE POTENTIALS OF MARINE ACTINOMYCETES

Objective: The aim of present studyis to isolate and characterize a novel actinomycetes strain from marine sediments collected at Kakinada coast. To evaluate antioxidant and antiproliferative activities of the crude methanolic extract of isolated actinomycetes.Methods: Actinomycetes was isolated from marine sediments collected at Kakinada coast using starch casein agar. Morphological, biochemical and molecular characterization was performed and the crude methanolic extract was used for determination of in vitro antioxidant activity and antiproliferative activity against MDA-MB 231 breast cancer cells.Results: The crude methanolic extract exhibited significant antioxidant activity with IC­50­ value in the range of 30-46 µg/ml in different radical scavenging assays. Moreover, the extract showed concentration dependent cytotoxicity against triple negative breast cancer cell line, MDA-MB 231 with IC50 of 42.5µg/ml. The extract also inhibited cell proliferation with IC50 value 44.1 µg/ml probably by arresting cell cycle at S phase. The antioxidant activity of the extract was strongly correlated with cytotoxic and antiproliferative activity.Conclusion: The isolated marine actinomycetes can be the potential source of antioxidants with the anticancer property
