LIFESTYLE INDICATOR SCHEME FOR GROUPING SIMILARITIES IN SOCIAL MEDIA

Even though huge efforts were produced for activity recognition by means of wise phones, there's comparatively minute concentrate on recognition of daily routines by means of wise phones. To cope with challenges of existing works, we provide Friend book, this can be a semantic-based system of friend recommendation for social systems according to sensor-wealthy wise phones. In recent occasions, when using the growth and development of systems of social networking, friend recommendations are suffering from plenty of consideration.  It is the friend recommendation system which was measured first using existence style information of user that was discovered from Smartphone sensors. Totally different from friend recommendation techniques according to social graphs in traditional services of social networking, Friend book found existence styles from user-centric data collected from sensors on wise phone and suggested potential buddies towards clients once they distribute comparable existence styles. Introduced system finds out existence styles concerning clients from user centric information, and assesses being much like existence styles among clients plus this method, client-server mode was created where every client might be a Smartphone that suits the use of user and servers are data centres

Prevalence, pattern, risk factors and outcome of stroke in women: a clinical study of 100 cases from a tertiary care center in South India

Background: Stroke is the leading cause of acquired disability and the third leading cause of death in women worldwide. There had been relatively few studies of stroke in women. Objective of the study was to study the prevalence, patterns, risk factors and outcome of stroke in women. A cross sectional study with case control comparison and prospective follow up at one month at ESIC Super speciality hospital, Hyderabad in South India.Methods: Total 100 stroke patients were identified over a period of 3 months and data collected on the basis of clinical proforma developed for the purpose.Results: Of 100 stroke patients, 31 were females. Ischemic stroke was seen in 25 (80.64%) females. Age was an important non-modifiable risk factor for stroke. Stroke was predominant among older women 23 (74.19%).  Mean age of stroke in females was 57 years. Menopause 27 (87.09%) was the predominant risk factor followed by hypertension in 25 (80.6%), dyslipidemia in 19 (70.3%) physical inactivity in 17 (54.8%) and diabetes in 12 (38.7%) females respectively. Majority of females 27 (87.09%) were uneducated as compared to males 27 (39.13%). The overall mortality in females was 3 (9.6%) as compared to males 3 (4.3%). 25 (89.2%) of females were ambulatory when compared to males 62 (93.9%). Conclusion: Stroke was common in older women and ischemic stroke was the predominate type of stroke.  Physical   inactivity was the significant risk factor in women when compared to men. Women are more likely to be disabled after stroke than men.

Offshore Wind Feasibility Study in India

Offshore wind provides a scalable alternative to conventional energy resources. This chapter provides an insight into various activities of Ministry of Earth Sciences for the realization of offshore wind in India. To understand the hurdles in policy frame work for offshore wind, the evolution of onshore wind policy is analyzed and suitable strategies for offshore wind are proposed. Wind resource assessment results indicated a high offshore potential at Kanyakumari, Rameshwaram, Gulf of Khambhat, and Gulf of Kutch. Commercial viability studies showed levelized cost of electricity (LCOE) of around Rs 10/kWh at identified sites for an internal rate of return (IRR) of 14%. Offshore light detection and ranging (LiDAR)-based data collection platform has been installed at Gulf of Khambhat and Kutch to obtain bankable wind data for the development of offshore wind farms. A preliminary design of substructure by exploring different concepts like monopile, jacket, and gravity-based foundations was carried out based on their suitability for site-specific environmental and soil data. The port facilities along Gujarat and Tamil Nadu coast were assessed, and installation methodology was developed considering marine spread along the Indian coast

Validating Prediction of a CGE Model of India: An Introspection

Although computable general equilibrium (CGE) models have been used extensively to evaluate the potential impact of economic reforms, few efforts have been made to assess the predictive power of the models. This paper attempts to test the performance of one such model, viz., Chadha, Pohit, Deardorff and Stern’s study of India’s unilateral trade/domestic policy reforms in the 1990s. Our model does not incorporate many of the rigidities/features of the Indian economy. Nevertheless, our model can perform quite well at simulating, if not forecasting, actual changes in sectoral output and export

Local niche differences predict genotype associations in sister taxa of desert tortoise

Aims: To investigate spatial congruence between ecological niches and genotype in two allopatric species of desert tortoise that are species of conservation concern. Location: Mojave and Sonoran Desert ecoregions; California, Nevada, Arizona, Utah, USA. Methods: We compare ecological niches of Gopherus agassizii and Gopherus morafkai using species distribution modelling (SDM) and then calibrate a pooled-taxa distribution model to explore local differences in species-environment relationships based on the spatial residuals of the pooled-taxa model. We use multiscale geographically weighted regression (MGWR) applied to those residuals to estimate local species-environment relationships that can vary across the landscape. We identify multivariate clusters in these local species-environment relationships and compare them against models of (a) a geographically based taxonomic designation for two sister species and (b) an environmental ecoregion designation, with respect to their ability to predict a genotype association index for these two species. Results: We find non-identical niches for these species, with differences that span physiographic and vegetation niche dimensions. We find evidence for two distinct clusters of local species-environment relationships that when mapped, predict an index of genotype association for the two sister taxa better than did either the geographically based taxonomic designation or an environmental ecoregion designation. Main conclusions: Exploring local species-environment relationships by coupling SDM and MGWR can benefit studies of biogeography and conservation. We find that niche separation in habitat selection conforms to genotypic differences between sister taxa of tortoise in a recent secondary contact zone. This result may inform decision making by agencies with regulatory or land management authority for the two sister taxa addressed here.Open access articleThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Design of a Protective Single-Dose Intranasal Nanoparticle-Based Vaccine Platform for Respiratory Infectious Diseases

Despite the successes provided by vaccination, many challenges still exist with respect to controlling new and re-emerging infectious diseases. Innovative vaccine platforms composed of adaptable adjuvants able to appropriately modulate immune responses, induce long-lived immunity in a single dose, and deliver immunogens in a safe and stable manner via multiple routes of administration are needed. This work describes the development of a novel biodegradable polyanhydride nanoparticle-based vaccine platform administered as a single intranasal dose that induced long-lived protective immunity against respiratory disease caused by Yesinia pestis, the causative agent of pneumonic plague. Relative to the responses induced by the recombinant protein F1-V alone and MPLA-adjuvanted F1-V, the nanoparticle-based vaccination regimen induced an immune response that was characterized by high titer and high avidity IgG1 anti-F1-V antibody that persisted for at least 23 weeks post-vaccination. After challenge, no Y. pestis were recovered from the lungs, livers, or spleens of mice vaccinated with the nanoparticle-based formulation and histopathological appearance of lung, liver, and splenic tissues from these mice post-vaccination was remarkably similar to uninfected control mice

Comparative Phylogeography of a Coevolved Community: Concerted Population Expansions in Joshua Trees and Four Yucca Moths

Comparative phylogeographic studies have had mixed success in identifying common phylogeographic patterns among co-distributed organisms. Whereas some have found broadly similar patterns across a diverse array of taxa, others have found that the histories of different species are more idiosyncratic than congruent. The variation in the results of comparative phylogeographic studies could indicate that the extent to which sympatrically-distributed organisms share common biogeographic histories varies depending on the strength and specificity of ecological interactions between them. To test this hypothesis, we examined demographic and phylogeographic patterns in a highly specialized, coevolved community – Joshua trees (Yucca brevifolia) and their associated yucca moths. This tightly-integrated, mutually interdependent community is known to have experienced significant range changes at the end of the last glacial period, so there is a strong a priori expectation that these organisms will show common signatures of demographic and distributional changes over time. Using a database of >5000 GPS records for Joshua trees, and multi-locus DNA sequence data from the Joshua tree and four species of yucca moth, we combined paleaodistribution modeling with coalescent-based analyses of demographic and phylgeographic history. We extensively evaluated the power of our methods to infer past population size and distributional changes by evaluating the effect of different inference procedures on our results, comparing our palaeodistribution models to Pleistocene-aged packrat midden records, and simulating DNA sequence data under a variety of alternative demographic histories. Together the results indicate that these organisms have shared a common history of population expansion, and that these expansions were broadly coincident in time. However, contrary to our expectations, none of our analyses indicated significant range or population size reductions at the end of the last glacial period, and the inferred demographic changes substantially predate Holocene climate changes
