On Distinguishing Non-Standard Interactions from Radiative Corrections in Neutrino-Electron Scattering

We present a contribution of higher order to neutrino-electron scattering that is a charged-current counterpart of both the anomalous axial-vector triangle and possible non-standard interaction contributions. It arises in the standard model with massive neutrinos, and renormalizes the nondiagonal axial-vector form-factor at low energies. We show that, due to the small size of radiative corrections, the neutrino-electron scattering still provides a discovery potential for some of the non-standard neutrino interactions proposed in the literature.Comment: 9 pages, 3 figures, change in title and context of the consideration, results of radiative corrections unchange

The Analysis of Diagnostic Assesment Result in Pisa Mathematical Literacy Based on Students Self-efficacy in Rme Learning

This research aimed to test RME learning with an effective scientific approach to improving mathematical literacy and self-efficacy, obtaining an overview of the mathematical literacy diagnostic assessment results that has high, medium and low self-efficacy as well as student difficulties in learning RME with a scientific approach. This research using mix method concurrent embedded with the subject of research is students class VIII. The research begins with a mathematical literacy diagnostic assessment and self-efficacy inventory then performed RME learning in experimental class and conventional learning in control class. Quantitative analysis was conducted to test the effectiveness of learning and deepened with the interview as a qualitative analysis. Learning RME with a scientific approach effective is marked by the achievement of classical completeness, the proportion of students\u27 mathematical literacy, self-efficacy and the difference in pre-post students\u27 mathematical literacy on RME learning better than conventional learning. The results of students\u27 mathematical literacy diagnostic assessment fit the criteria of self-efficacy students except for medium mathematical literacy that having high self-efficacy. Student difficulties in RME learning with the scientific approach are based on the results of mathematical literacy diagnostic assessment, namely language skills problem, the capacity to understand, create strategies, and create the algorithm

Clear Experimental Signature of Charge-Orbital density wave in Nd1−x_{1-x}Ca1+x_{1+x}MnO4_{4}

Single Crystals of Nd$_{1-x}$Ca$_{1+x}$MnO$_{4}$ have been prepared by the travelling floating-zone method, and possible evidence of a charge -orbital density wave in this material presented earlier [PRB68,092405 (2003)] using High Resolution Electron Microscopy [HRTEM] and Electron Diffraction [ED]. In the current note we present direct evidence of charge-orbital ordering in this material using heat capacity measurements. Our heat capacity measurements indicate a clear transition consistent with prior observation. We find two main transitions, one at temperature $T_{_H}=310-314$ K, and other at $T_{_A}=143$ K. In addition, we may also conclude that there is a strong electron-phonon coupling in this material.Comment: 7 pages, 8 figure

Ergonomic evaluation of subjects involved in orange (Citrus sinensis) handling operations in Yanlemo Market Kano State

Ergonomic evaluation of subjects involved in orange handling operation in Kano State was conducted. Anthropometric parameters were evaluated, where they were found to vary with age amongst the subjects selected. 20th and 80th percentiles of the dimensions were computed and recommended for usage in design of the relevant orange handling equipment. To evaluate the Physiological parameters, sorting/grading operations and washing operations were selected for this study. Results obtained revealed that, heart beat rate, oxygen consumption and energy expenditure varied amongst the subjects with age. Muscular stress and postural disorder were also studied. Comparing the parameters obtained during sorting/grading operation and that obtained during washing operations revealed that orange operations resulted to superior drudgery and musculoskeletal disorders.Keywords: Anthropometrics, Energy expenditure, Drudgery, Operations and Musculoskeletal disorde

A Conceptual Framework for Knowledge Management Implementation in Organizations

This study aimed to identify the processes associated with knowledge management implementation and develop a framework with different stages that combines these processes to guide the initiative for implementing knowledge management in organizations. The study was approached from a theoretical perspective. The study contributes to the knowledge management literature by developing a conceptual framework of knowledge management. A comprehensive review was conducted of recent progress and the rapidly growing number of published studies on knowledge management implementation. The review revealed ten critical processes that should be considered to ensure successful knowledge management initiatives. Based on that, a framework for knowledge management implementation is proposed. Specifically, the processes associated with implementing knowledge management are logically distributed among the PDCA framework promulgated and reflecting the four domains of the Plan–Do–Check–Act, which has consistently shown the capability to encompass all processes of effective knowledge management implementation. The framework can be used as a reference for implementing knowledge management initiatives in organizations. Finally, this study emphasizes that continuous process methods are significant in implementing knowledge management initiatives. By placing knowledge management implementation processes in the PDCA cycle, task-based knowledge can be better recognized and understood

Fcc breathing instability in BaBiO_3 from first principles

We present first-principles density-functional calculations using the local density approximation to investigate the structural instability of cubic perovskite BaBiO_3. This material might exhibit charge disproportionation and some evidence thereof has been linked to the appearance of an additional, fourth peak in the experimental IR spectrum. However, our results suggest that the origin of this additional peak can be understood within the picture of a simple structural instability. While the true instability consists of an oxygen-octahedra breathing distortion and a small octahedra rotation, we find that the breathing alone in a fcc-type cell doubling is sufficient to explain the fourth peak in the IR spectrum. Our results show that the oscillator strength of this particular mode is of the same order of magnitude as the other three modes, in agreement with experiment.Comment: submitted to PRB, completely revised version after referee repor

Variable structure based control strategy for treatment of HCV infection

Hepatitis C is such a harmful disease which can lead to serious health problems and it is caused by the Hepatitis C Virus (HCV) which causes liver inflammation and sometimes liver cancer. In this work, the control treatment strategy for HCV infection has been proposed. The advanced nonlinear dynamical mathematical model of HCV that has two control inputs and three state variables such as virions, infected hepatocytes and uninfected hepatocytes are considered for controller design in this research work. Moreover, four nonlinear controllers such as the Fractional Order Terminal Sliding Mode Controller (FOTSMC), Integral Terminal Sliding Mode Controller (ITSMC), Double Integral Sliding Mode Controller (DISMC) and Integral Sliding Mode Controller (ISMC) have been proposed in this work for HCV infection control inside the human body. In order to control the amount of uninfected hepatocytes to its required maximum safe limit, controllers are designed for antiviral therapy in which the amount of virions and infected hepatocytes are tracked to zero. One control input is ribavirin which blocks virions production and the other is pegylated interferon (peg-IFN-a) that acts as reducing infected hepatocytes. By doing so, uninfected hepatocytes increase and achieve the required maximum safe limit. To prove the stability of the whole system, Lyapunov stability analysis is used in this work. Simulation results and comparative analysis are carried out by using MATLAB/Simulink. It can be depicted from the given results that the virions and infected hepatocytes are reduced to their required levels completely using FOTSMC and the Sustained Virologic Response (SVR) rate is also enhanced in it. It reduces the treatment period as compared to previous strategies introduced in the literature and also system behaves very nicely even in the presence of un-modeled disturbances

Variable Structure-Based Control for Dynamic Temperature Setpoint Regulation in Hospital Extreme Healthcare Zones

In critical healthcare units, such as operation theaters and intensive care units, healthcare workers require specific temperature environments at different stages of an operation, which depends upon the condition of the patient and the requirements of the surgical procedures. Therefore, the need for a dynamically controlled temperature environment and the availability of the required heating/cooling electric power is relatively more necessary for the provision of a better healthcare environment as compared to other commercial and residential buildings, where only comfortable room temperature is required. In order to establish a dynamic temperature zone, a setpoint regulator is required that can control the zone temperature with a fast dynamic response, little overshoot, and a low settling time. Thus, two zone temperature regulators have been proposed in this article, including double integral sliding mode control (DISMC) and integral terminal sliding mode control (ITSMC). A realistic scenario of a hospital operation theater is considered for evaluating their responses and performance to desired temperature setpoints. The performance analysis and superiority of the proposed controllers have been established by comparison with an already installed Johnson temperature controller (JTC) for various time spans and specific environmental conditions that require setpoints based on doctors’ and patients’ desires. The proposed controllers showed minimal overshoot and a fast settling response, making them ideal controllers for operation theater (OT) zone temperature control

Online information needs of cancer patients and their organizations

Increasingly patients, relatives and carers are accessing health information via the internet. However, the health profession and people affected by cancer are becoming concerned with the quality of that information. A European survey was conducted under the auspices of the FP7 European Commission funded Eurocancercoms project1 during the period September 2010–March 2011. Its aim was to assess current online information needs of people with cancer particularly those who seek information using online social media technologies and the internet more broadly. A literature review was undertaken to gain a greater understanding of health seeking behaviour regarding cancer patients’ information needs and patient preferences for accessing different formats and media. This was used to inform the design and validation of online pan-European, multi-lingual questionnaires distributed via patient organizations and via specific Eurocancercoms partner organizations. This paper presents the results of this survey and suggests recommendations to be incorporated into the design of the online platform, ecancerHub, one of the intended outcomes of the Eurocancercoms project following this research. People want a wide variety of easy to find, easy to understand accurate information about cancer and how it is likely to impact on their everyday lives and on those close to them. They differ in the amount and detail of the information they would like and on their ability to identify quality information and understand it sufficiently to base their health-care decisions on. The majority of respondents raised the issue of quality of information and many requested recommendations of websites by the people who usually influence them most, the health professionals involved in their care
