Phosphorus Deficiency Phosphorous Deficiency in Animals
No full textPhosphorus deficiency is a condition, in which Phosphorus is insufficient or is not utilized properly. Phosphorus is a mineral that is vitally important to the normal metabolism of numerous compounds and in solution an acid that, with sulphur, must be neutralized by the base forming ions of sodium, potassium, calcium, and magnesium. About 70 of retained Phosphorus combines with calcium in bone and tooth structure. Phosphorus is the principal element in the structure of the nucleus and cytoplasm of all tissue cells. It is also a universally distributed component of skeletal, nerve, and muscle tissues. A reduced concentration of phosphorus in the blood serum is a disorder known as hypophosphatemia. Phosphorus deficiency may cause bone diseases such as rickets in animals. An improper balance of phosphorus and calcium may cause osteoporosis. Dietary sources of Phosphorus include milk products, egg yolk, legumes, nuts, andwhole grains.

Design of Ajanta System for Mobile Agent Programming
No full textWe describe the architecture and programming environment of Ajanta, a Java-based system for programming applications using mobile agents over the Internet. Agents are mobile objects which are hosted by servers on the network. Ajanta provides primitives for creating and dispatching agents, securely controlling agents at remote sites, and transferring agents from one server to another. For secureaccess to server resources by visiting agents, a proxy-based access control mechanism is used. The Ajanta design includes mechanisms to protect an agent's state and prevent misuse of its credentials. We describe in this paper migration patterns for programming an agent's travel path. A pattern encapsulates the abstract notion of agent mobility. Pattern composition allows one to build complextravel plans using some basic migration patterns. Finally,we present three agent-based distributed applications implemented using the Ajanta system. These include a middleware for sharing files over the Internet, a distributed calendar management system, and an agent-based middleware for distributed collaborations.Tripathi, Anand; Karnik, Neeran M.; Ahmed, Tanvir; Vora, Manish K.; Pathak, Mukta; Prakash, Arvid; Kakani, Vineet.

Stoic beliefs and health: Development and preliminary validation of the Pathak-Wieten Stoicism Ideology Scale
No full text© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved. No commercial use is permitted unless otherwise expressly granted. Introduction We developed and validated a new parsimonious scale to measure stoic beliefs. Key domains of stoicism are imperviousness to strong emotions, indifference to death, taciturnity and self-sufficiency. In the context of illness and disease, a personal ideology of stoicism may create an internal resistance to objective needs, which can lead to negative consequences. Stoicism has been linked to help-seeking delays, inadequate pain treatment, caregiver strain and suicide after economic stress. Methods During 2013-2014, 390 adults aged 18+ years completed a brief anonymous paper questionnaire containing the preliminary 24-item Pathak-Wieten Stoicism Ideology Scale (PW-SIS). Confirmatory factor analysis (CFA) was used to test an a priori multidomain theoretical model. Content validity and response distributions were examined. Sociodemographic predictors of strong endorsement of stoicism were explored with logistic regression. Results The final PW-SIS contains four conceptual domains and 12 items. CFA showed very good model fit: root mean square error of approximation (RMSEA)=0.05 (95% CI 0.04 to 0.07), goodness-of-fit index=0.96 and Tucker-Lewis Index=0.93. Cronbach's alpha was 0.78 and ranged from 0.64 to 0.71 for the subscales. Content validity analysis showed a statistically significant trend, with respondents who reported trying to be a stoic 'all of the time' having the highest PW-SIS scores. Men were over two times as likely as women to fall into the top quartile of responses (OR=2.30, 95% CI 1.44 to 3.68, P<0.001). ORs showing stronger endorsement of stoicism by Hispanics, Blacks and biracial persons were not statistically significant. Discussion The PW-SIS is a valid and theoretically coherent scale which is brief and practical for integration into a wide range of health behaviour and outcomes research studies

Atomic Reconstruction of Au Thin Films through Interfacial Strains
No full textInterfaces play a critical thermodynamic role in the existence of multilayer systems. Due to its utility in bridging energetic and compositional differences between distinct species, the formation of interfaces inherently creates internal strain towards bulk atoms due to the reorganization needed to accommodate such interface. We report the effect of scaling interfacial stress due to deposition of different adlayers on a host thin metal film. Intrinsic property differences between host and de-posited metal atoms result in varying degree of composition and energy gradient within the interface. Interfacial stress can increase defects in the host leading to; i) energy dissipation and reorganization to minimize surface energy, ii) increased material strength. We infer that dissipation of interfacial stress induces defect migration, hence bulk and surface atomic reconstruction as captured by the surface roughness and grain size reduction coupled with concomitant increase in material strength.This is a manuscript of the article published as Martin, Andrew, Jiahao Chen, Chuanshen Du, Manish Kumar, Ian D.

Social entrepreneurship, governmentality & the Left
No full textThis paper offers a critique of the location of social entrepreneurship in the imaginaries of an advanced liberal social economy . Social entrepreneurship is used in a broad sense to refer to innovative, sustainable solutions to social problems, and this paper is agnostic towards organisational structures or the use of earned income which might be understood to circumscribe the practice of social enterprise. This chapter therefore, rejects Reiss’ (1999,1) assertion that social entrepreneurship refers simply to the “application of sound business practices to the operation of non-profit organizations” and is closer to the social innovation school of thought advocated by Dees & Anderson (2006). By doing so, the author asserts the need for nation states to take an active role through policy innovation and the co-ordination of the social economy

ORCID: 0000-0002-2750-8483 (Shubham Pathak).Natural disasters have been a significant hurdle in the economic growth of middle-income developing countries. Thailand has also been suffering from recurring flood disasters and was most which are severely affected during the 2011 floods. This paper aims to identify the various factors that impact the speed of disaster recovery among the Small and Medium Enterprises (SMEs) severely affected by the floods in Pathumthani province in central Thailand, and how it is related to its speed decision of neighbours SMEs. The methodology adopts a spatial econometric model, to analysis and understand each of the chosen factors' impact. The findings include the impact of disaster resilience, mitigation and planning at the SME level as well as the government level. The absence of accurate perception of actual risk, flood insurance and disaster management planning before the 2011 floods had contributed to the severity of the impacts during the 2011 floods
Role of interface-affected dislocation motion on the strength of Mg/Nb nanolayered composites inferred by dual-mode confined layer slip crystal plasticity
No full textIn this work, we present a nanostructure-sensitive crystal plasticity model for the deformation response of nanolaminate composites. The model is applied to investigate the strength of Mg/Nb nanocomposites, wherein the Mg phase has either a hexagonal close-packed (HCP) or a body-centered cubic (BCC) crystal structure. To account explicitly for the effects of layer thickness and biphase interface on crystallographic slip, the model features a hardening law, called dual-mode confined layer slip (CLS). The model is applied to a suite of stress-strain measurements made on Mg/Nb nanocomposites, varying layer thickness, texture, and interface structure. Experiments show that the BCC/BCC Mg/Nb nanocomposites achieve substantially higher strength than the HCP/BCC nanocomposites. Apart from the finer layer thicknesses, the model indicates that the pseudomorphic BCC Mg phase contributes to strength by increasing the slip strengths of the 〈111〉 slip modes compared to the 〈a〉 slip modes in HCP Mg. It also suggests that the coherent interface poses less resistance to dislocation motion than the incoherent interface. It is, therefore, found that the BCC/BCC composite strength benefited from both the confinement on dislocation motion imposed by the reduced layer thickness and higher inherent strength of its BCC phase, but that it would be even higher if the interface was not a sharp coherent interface.This is a manuscript of the article Published as Wang, Jiaxiang, Marko Knezevic, Manish Jain, Siddhartha Pathak, and Irene J.
