Synthesis and Characterization of Samarium doped SrBi 2x O 4 oxides

Sm doped SrBi2-xO4 oxides were prepared by sol gel method via nitrate citrate route with ‘x’ values ranging from 0.0, 0.1, 0.2, 0.3, and 0.4 (samples C0 C4). X-ray powder diffraction analysis reveals the single phase monoclinic structure with the space group of P/2m. Rietveld refinement of unit cell structure shows lowered agreement factors Rp , Rwp and Rexp for all the samples. Average crystallite size was determined by Scherrer’s relation in the range of ̴ 36 45nm. Magnetic properties of the samples were analyzed by using Vibrating Sample Magnetometer at room temperature which reveals a weak ferromagnetic behaviour for C1 to C4 and diamagnetic behaviour for sample C0. EPR studies recorded at liquid helium temperature show a single absorption peak with defect line content. Optical absorption spectra of the prepared samples were recorded in UV visible region from 200nm to 800nm. FT-IR spectra of the samples were recorded at room temperature, which show the characteristic absorptions at 853 cm -1 and 533 cm –1 corresponding to the tetrahedral and octahedral sites. SEM studies show the particles were agglomerated with rod like structure. The combined TGA – DSC measurements show important stages of decomposition with no phase transition.
Geovisual Analytics Environment for Supporting the Resilience of Maritime Surveillance System

This paper presents an original approach for supporting the resilience in Maritime Domain Awareness, based on geovisual analytics. While many research projects focus on developing rules for detecting anomalies at by automated means, there is no support to visual exploration led by human operators. We investigate the use of visual methods for analyzing mobility data of ships. Behaviors of interest can be known (modeled) or unknown, asking for various ways of visualizing and studying the information. We assume that supporting the use of geovisual analytics will make the exploration and the analysis process easier, reducing the cognitive load of the tasks led by the actors of maritime surveillance. The detection and the identification of threats at sea are improved by using adequate visualization methods, regarding the context of use. Our suggested framework is based on ontologies for maritime domain awareness and geovisual analytics environments, coupled to rules.
The selection of social actions in families: II. Parental investment

One of the most widely used applications of kin selection concerns the investment that parents provide to their young. In particular, Trivers’ concept of parent–offspring conflict was enthusiastically adopted by biologists and applied to many aspects of parent–offspring interactions, including reproductive effort, clutch size, brood reduction, sex ratios, and dispersal and germination strategies. In this paper, parental and offspring strategies are examined with regard to the amount of resources that parents invest in each offspring; this determines the size and average fitness of the newly independent young. Parental investment is used here as a model system to compare the results of genetic models of social actions with those of autonomous gene models, and to examine the relative merits of using measures of inclusive or collective fitness. To this end, the extent of conflicts over parental investment is derived for two kinds of families, which differ in the way that the young compete with each other (equal versus unequal competition). Finally, the ways in which conflicts are resolved and the relative importance of conflict and cooperation in raising young are discussed.
The Role of Peer Bystanders in School Bullying: Positive Steps Toward Promoting Peaceful Schools

Bullying and harassment are pervasive problems in schools, with interventions to counter bullying now regarded as a matter of high priority by educational authorities. This article considers the impact of bullying on victim and bully. It also explores the role of peers as bystanders in school bullying. Australian research is described, examining peer perceptions and responses, together with factors associated with bystander behavior. The authors' research suggests that teaching peers to cope may go some way to combating bullying in school by effecting change at the peer group level. Features of a universal coping program are given and common elements of successful antibullying interventions are highlighted. It is clear that peers play a central role in school bullying and teaching young people strategies to cope may be a positive step toward promoting peaceful schools.
The Influence of Knowledge Management on the Competitiveness of Government Organisations

Due to increasing instability in modern economies Government organizations need to become competitive. In relation to this Knowledge Management (KM) has been rapidly growing recently as a source of influence on organisational development practices. During the past decade research has largely failed to show the importance of KM initiatives in creating synergy with other initiatives that lead towards organizational competitiveness. This investigation addresses whether KM holistically influences organisational excellence, specifically in the context of the government sector. In order to determine the relationships between KM and organisational excellence identified in the literature, and increasingly used in practice, a quantitative survey approach was undertaken using a series of researcher-developed scales. Building on the literature review Organisational Competitiveness (OC) was identified as important in relation to KM. The conceptual framework that was designed tested the concept of the holistic influence of KM on organisational excellence. Some six hundred and twenty five valid responses were collected from top and middle management from fifty four government organizations in the Kingdom of Bahrain. Following this a model was statistically tested according to the research hypothesis by regression analysis then Structural Equation Modelling (SEM). The results revealed strong and significant correlations amongst organisational development practices. Although the holistic influence of the model could not be confirmed, findings show positive KM influence on organisational development practices, thus KM is an essential factor for government organisations. This concept of a holistic model needs to be further subjected to empirical investigation to explore its viability.
Study of Thyroid Hormonal Status in Preeclamptic Patients

The physiological changes in the thyroid gland during pregnancy were well understood. Serum TSH levels were significantly increased without changes in free T 3 and T 4 in preeclamptic patient compared to normal pregnancy. This study tried to find out a possible relationship between preeclampsia and thyroid profile. The present study determines thyroid hormonal levels in cases of preeclampsia in the third trimester of pregnancy. TSH level were significantly higher in preeclamptic group as compared to control. A prospective case control study was conducted in the Department of Obstetrics and Gynecology, Chittagong Medical College Hospital, Chittagong. Thyroid hormone, namely Triiodothyronine (Free T 3 ), Thyroxine (Free T 4 ) and Thyroid Stimulating Hormone (TSH) were evaluated by radioimmunoassay. In this case control study pregnant women with preeclampsia were recruited after the diagnosis were made and compared with equal number of healthy normotensive pregnant women in third trimester. The data were analyzed using unpaired ‘t’ test and chi-square test. When P value were <0.05, the result were accepted as significant. Increase TSH level were associated with a risk for occurrence of preeclampsia DOI: http://dx.doi. org/10.3329/medtoday.v25i2. 17922 Medicine Today 2013 Vol.25(2): 63-66
Productive and Unquestioning Data Duplicate Detection Using REVISE

Duplicate detection consists in detecting multiple types of representations of a same object, and every object represented in a database source. Duplicate detection is relevant data cleaning and data integration applications and has been studied extensively for relational data describing a single type of object in a single data table.New novel comparison strategy that uses graph model in terms of relationships proposed for hierarchical data. Insteadpairs of objects at any level of the hierarchy are compared in an order that depends on their relationships. We use stringer to evaluate the quality of the clusters obtained many unconstrained clustering algorithms used in concert with approximate join techniques.We present new novel iterative algorithm for duplicate detection system called REVISE. REVISE access to re-examining an object influencing neighbors turn out to be duplicates. The main aim of the project is to detect the duplicate in the structured data. Proposed system focus on a specific type of error namely fuzzy duplicates,The problem of detecting duplicate entities that describe the same real-world object is an important data cleansing task which is important to improve data quality.
Practical Scale for the Management of Head Injured Patients in Coma or with Possible Multiple Injuries

Background: Aggressive total management of all patients with severe closed head injuries requires much effort and many resources. A clinical scale has been developed for assessing the depth and duration of impaired consciousness. Method: A protocol for emergency triage of head injuries was presented. Its objectives were to increase the quality of clinical assistance, to avoid unnecessary emergency neurosurgical consultation and to reduce the interhospital transfer of patients. Result: Emergency neurosurgical consultation was reduced by 80% in Grade 1 and by 85% in Grade II. Moreover, a significant reduction of Hospital readmissions was recorded 1vs 11 (p = 0.01). Conclusion: This head injury chart enables every member of the staff in casualty to view the evolution of any patient at any given moment.
From nucleation to growth of catalyst-free GaN nanowires on thin AlN buffer layer

We demonstrate that thin AlN buffer layers improve the orientation of GaN nanowire grown on Si 111 . The deposited GaN initially forms into islands which act as a seed for the wires. By raising substrate temperature, the actual amount of grown material decreases but wire density increases and well-separated wires are achieved. Fast wire length growth rate at high growth temperature is assigned to an enhancement of adatom diffusion. The upper limit of length growth rate is determined by the supply rate of active nitrogen. © 2007 American Institute of Physics. DOI: 10.1063/1.2817941
Quantifying the uncertainty in estimates of surface-atmosphere fluxes through joint evaluation of the SEBS and SCOPE models

Accurate estimation of global evapotranspiration is considered to be of great importance due to its key role in the terrestrial and atmospheric water budget. Global estimation of evapotranspiration on the basis of observational data can only be achieved by using remote sensing. Several algorithms have been developed that are capable of estimating the daily evapotranspiration from remote sensing data. Evaluation of remote sensing algorithms in general is problematic because of differences in spatial and temporal resolutions between remote sensing observations and field measurements. This problem can be solved in part by using soil-vegetation-atmosphere transfer (SVAT) models, because on the one hand these models provide evapotranspiration estimations also under cloudy conditions and on the other hand can scale between different temporal resolutions.
Functional Analysis Of Grapevine STS7 And STS22 Promoters

Stilbenic compounds are a group of phytoalexins that are produced by a limited number of plant species including grapevine to defend against diseases. Stilbene synthase (STS) is the key enzyme that catalyzes the biosynthesis of stilbenic compounds. Previous results indicated a significant increase in the abundance of transcripts of STS7 and STS22 genes in powdery mildew-infected Cabernet Sauvignon leaves. I isolated the promoter sequences of STS7 and STS22 from grapevine Vitis aestivalis ‘Norton’ (Va) and Vitis vinifera ‘Cabernet Sauvignon’ (Vv) and studied their activities in transgenic plants. The results showed high activity of VaSTS7 and VaSTS22 promoters in transgenic plant leaves at all developmental stages. VaSTS22 promoter was activated mainly along the veins, whereas VaSTS7 promoter was activated in leaf tissues in transgenic plants. Both VaSTS22 and VvSTS22 promoters showed higher activity than VaSTS7 promoter in transgenic plant leaves when treated by salicylic acid. The activity of VaSTS22 promoter increased in transgenic plant leaves at 10 days post inoculation with powdery mildew, but neither VaSTS7 nor VvSTS22 promoter showed significant changes in transgenic plants after inoculation. These assays demonstrated that STS7 and STS22 promoter differently regulated a reporter gene in roots, leaves, and also in response to salicylic acid and powdery mildew in transgenic plants. My results provided new knowledge on the involvement of STS genes in defense against biotic and abiotic factors.

What is public service improvement

Five conceptual models of public service improvement are derived from the large literature on organizational effectiveness. These are the goal, systems-resource, internal process, competing values and multiple constituency models. The strengths and weaknesses of each of these models is evaluated and a working definition of improvement is proposed. This emphasizes that concepts and measures of public service improvement are political rather than technical, and contingent rather than universal. Conclusions are drawn on the implications for academic research and policy development.
Ab initio calculation of the electronic and optical excitations in polythiophene: Effects of intra- and interchain screening

We present an ab initio calculation of the electronic and optical excitations of an isolated polythiophene chain as well as of bulk polythiophene. We use the GW approximation for the electronic self-energy and include excitonic effects by solving the electron-hole Bethe-Salpeter equation. The inclusion of interchain screening in the case of bulk polythiophene drastically reduces both the quasiparticle band gap and the exciton binding energies, but the optical gap is hardly affected. This finding is relevant for conjugated polymers in general.
Estimation of genetic parameters and trends for milk fat and protein percentages in Iranian Holsteins using random regression test day model

Abstract. The aim of the present study was to estimate the genetic parameters and trends for fat and protein percentages of milk in Iranian Holsteins calving between 2001 and 2010 using the random regression test day model. Data set included 505 160 test day records that were collected by the Animal Breeding Centre of Iran. The Legendre polynomial functions of orders (5, 5) and (5, 6) were chosen to fit the additive genetic and permanent environmental effects of fat and protein percentages, respectively. Estimated heritabilities ranged from 0.053 to 0.232 and 0.111 to 0.259 for fat and protein percentages, respectively. The averages of estimated breeding values were −8.61 and −3.15 and annual genetic trends were −0.74 kg and −0.64 kg for fat and protein percentages, respectively. Negative genetic trends for fat and protein percentages are likely the result of major emphasis on milk yield in the breeding plan of Iranian Holsteins.
The Star Formation Reference Survey – III. A multiwavelength view of star formation in nearby galaxies

We present multi-wavelength global star formation rate (SFR) estimates for 326 galaxies from the Star Formation Reference Survey (SFRS) in order to determine the mutual scatter and range of validity of different indicators. The widely used empirical SFR recipes based on 1.4 GHz continuum, 8.0 $\mu$m polycyclic aromatic hydrocarbons (PAH), and a combination of far-infrared (FIR) plus ultraviolet (UV) emission are mutually consistent with scatter of $\raise{-0.8ex}\stackrel{\textstyle }5\times10^9$ L$_{\odot}$ or with implied far-UV extinction <1 mag, the UV spectral slope gives extinction corrections with 0.22~dex uncertainty.
Morphometrical analysis of the p53 tissue marker in prostatic adenocarcinoma and its relationship to Gleason score and PSA level

Purpose: Prostate cancer is one of the most common malignancies worldwide. The possible prognostic value of tissue markers, such as p53, may give a better understanding of this disease, improve staging accuracy, and help in choosing optimal treatment. In this study, we examined p53 expression and its correlation with Gleason score, prostate–specific antigen (PSA) levels, and patient age in a Slovenian population. Methods: This retrospective pilot study included 25 radical prostatectomy patients. The immunohistochemical expression of p53 was determined and expressed as a p53 index. In addition, correlations between p53 index, Gleason score before and after prostatectomy, PSA level, and patient age were statistically evaluated. Results: The p53 tissue marker was unevenly distributed in prostate cancer independently of local Gleason pattern; however, its expression correlated with Gleason score after prostatectomy and showed borderline correlation with PSA. There were also statistically significant correlations between Gleason score before and after prostatectomy, PSA level, and patient age. Conclusions: Despite the low number of cases presented in this study, our results demonstrate that p53 may have predictive value in prostate cancer. Thus, p53 is a promising tissue marker that can be used as an additional diagnostic parameter.
Investigating The Role Of the Cellular Prion Protein in Ca2+ Metabolism And Alzheimer's Disease

The cellular prion protein (PrPC) is a highly conserved cell-surface glycoprotein expressed in almost all mammalian tissues, in particular in the central nervous systems. The bad reputation acquired by PrPC originates from its capacity to convert into an aberrant conformer (PrPSc), which is the major component of the prion, the unconventional infectious particle causing fatal neurodegenerative disorders, known as prion diseases. Both the mechanism of prion related neurodegeneration and the physiologic role of PrPC are still unknown. However, use of animal and cell models has underscored a number of putative functions for PrPC, suggesting that it could serve in cell adhesion, migration, proliferation and differentiation, possibly by interacting with extracellular partners, and/or by taking part in multi-component signaling complexes at the cell surface. An intriguing hypothesis, based on increasing amounts of data that may explain the multifaceted behavior of PrPC, entails that the protein is involved in the regulation of Ca2+ homeostasis One major part of the present thesis deals with a close investigation of the alleged regulation of Ca2 homeostasis by PrPC. This study was carried out by monitoring local Ca2+ movements in primary cultures of cerebellar granule neurons (CGN) - obtained from PrP-knockout mice and transgenic PrPC-expressing mice - subjected to various stimuli. Measurements of Ca2+ fluxes in different cell domains were accomplished using the Ca2+- sensitive photo-protein aequorin genetically targeted to different cell domains (plasma membrane, cytosol, lumen of the endoplasmic reticulum and mitochondrial matrix). We found that, with respect to PrPC-expressing neurons, the absence of PrPC caused alterations of local Ca2+ movements, indicating that PrPC may be part of the cellular system(s) deputed to avoid toxic neuronal Ca2+ accumulation. As for the molecular mechanisms by which PrPC controls Ca2+ homeostasis, we found that this could be accomplished through the modulation of p59Fyn- and p42/p44-ERK-dependent signaling pathways. Another topic studied in this thesis stemmed from recent reports indicating that PrPC could acts as a high-affinity receptor for amyloid-beta (Abeta) peptides implicated in Alzheimer's disease. The possibility that PrPC-Abeta interactions may impair synaptic plasticity is, however, still highly debated. Thus, given that Ca2+ is intimately related to synaptic plasticity, we investigated whether Abeta peptides affected Ca2+ metabolism in a PrPC-dependent manner using the above-mentioned strategies and cell paradigms. The obtained results showed that interactions between PrPC and Abeta oligomers may cause Ca2+ accumulation following activation of store-operated Ca2+ entry, and that this may occur via a PrPC-dependent activation of p59Fyn kinase.
COST ANALYSIS OF FINANCING DECISIONS: A STUDY OF PHARMACEUTICAL INDUSTRY IN INDIA

Capital structure refers to the proportion in which various long-term financial sources are employed. Over the years, the decisions related to select the appropriate sources of fund are the most important decisions that a firm has to take. This is because the capital structure or the choice of selecting the appropriate sources of fund can affects the cost of capital, net profit, earning per share, and dividend payout ratio as well as the liquidity position of the firm. So, therefore a capital structure is a very important determinant for the value of a firm. This paper attempts to measure the effect of change in capital structures on the cost of capital of various pharmaceutical companies. Similarly, this study analyse the significance of cost of capital for the period 2007-2011. To analyse the set objectives, the paper include the trend analysis of detail financial information of three most reputed pharmaceutical companies i;e CIPLA Ltd, Auribindo Pharma Ltd, Cardila Health Care Ltd.
