Overview of Indexes Used in NOSQL Databases of MongoDB Architecture

The present day transactions result into petabytes of data collected and the credit almost goes to the booming ICT industry. The data received is able to detect the hidden patterns for the enterprises and research industry and help them to improve their traditional methods. However the data is unstructured and requires new innovative technologies to be implemented in the architecture handling big data. In the present paper, we have tried to explore the NOSQL database handling techniques and specifically the indexes that help to reduce the time complexity to handle the unstructured data. This paper is divided into four sections where the first section compares the DBMS and DSMS followed by the literature review on this technique and introduction to the MongoDB architecture and overview of NOSQL databases. The fourth section handles the types of the databases, it’s index types. Fifth section describes the performance comparison of the various MongoDB with RDBMS

The human factor: Re-organisations in public health policy

INTRODUCTION: Public health policy-making activities are currently split between local authority and NHS organisations. Despite an increasing body of research on evidence-based policy (EBP), few studies explore the process of policy-making. Little is known about how policies are made in a local context, or how (scientific) evidence is used. Previous research has ignored the 'human element' in EBP. Social network analysis (SNA) techniques are becoming increasingly important in health policy. This paper describes an innovative study giving a fresh perspective on policy-making processes in public health. METHODS: A social network analysis of public health policy making networks in Greater Manchester based on publicly available data (documents, websites and meeting papers) and an electronic survey, asking actors to nominate those who influenced their own views, those who were powerful, and those who were a source of evidence or information. RESULTS AND CONCLUSIONS: Policy-making networks are described. Formal executive roles are loosely related to perceived influence and power. Evidence-seeking networks are less coherent, with key organisations not represented. These data indicate the importance of collaboration and good relationships between researchers and policy-makers, but few academic researchers with a direct impact on health policy were identified within the networks

Nanoparticle compositions and methods for making and using the same

A composition that includes solid lubricant nanoparticles and an organic medium is disclosed, as well as nanoparticles that include layered materials. Methods of producing a nanoparticle by milling layered materials and of making a lubricant are provided. The method includes milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant
