This review article presents an overview of instruments available on the market for measurement of particulate matter. The main instruments and methods of measuring concentration (gravimetric, optical, and microbalance) and size distribution Scanning Mobility Particle Sizer (SMPS), Electrical Low Pressure Impactor (ELPI), and others were described and compared. The aim of this work was to help ...

BACKGROUND Measuring team factors in evaluations of Continuous Quality Improvement (CQI) may provide important information for enhancing CQI processes and outcomes; however, the large number of potentially relevant factors and associated measurement instruments makes inclusion of such measures challenging. This review aims to provide guidance on the selection of instruments for measuring team-l...

Background: Due to the low rate of breastfeeding among working mothers and support of interventions to increase the duration of breastfeeding, this systematic review conducted to evaluate psychometric properties of instruments measured mother’s perception of Breastfeeding Support. Materials and Methods: The search was carried in English language databases including Medline (via PubMed), Scopus,...

In October 1998, the CLARE measurement campaign took place in Chilbolton, England. A variety of collocated instruments performed measurements on the clouds. Among the instruments were a microwave radiometer, lidars and radars. Also, particle size measuring probes were operated during flights through the clouds. Estimates of the cloud microphysical properties may be made by combining the measure...

INTRODUCTION Palliative care is closely linked to the concept of quality of life. In this work we will focus our interest on the need to assess quality of life in oncologic paediatric palliative care. OBJECTIVE To describe/compare instruments for measuring quality of life in Oncologic paediatric palliative care. MATERIAL AND METHODS A literature review of the sever a instruments for measuri...

Factor analytic findings from culturally specific instruments measuring traditionalism as one aspect of cultural identity are described, based on the self-reports of American Indian children and parents. Findings indicate that traditionalism is a multidimensional construct that can be measured reliably. Results are important because few psychometrically adequate instruments exist to assess eith...

In recent years measuring instruments have adopted general-purpose operating systems to offer the user a broader functionality that is not necessarily restricted towards measurement alone. Additionally the trend to the internet of things from which measuring instruments are not immune, e.g. smart meters and traffic enforcement cameras just to name a few, brings forth security questions. In this...

The purpose of this study was to examine reliability and validity of a new method of measuring hand size in which a tape measure is wrapped around the hand in a figure-of-eight pattern. In the first experiment, two testers measured hand size in 60 individuals with no recent history of injury or surgery. Intraclass correlation coefficients of 0.99 and 0.97 indicated high intratester and intertes...

In this paper, we attempt to establish quantum measurement theory in the Heisenberg picture. First, we review foundations of quantum measurement theory, that is usually based on the Schrödinger picture. The concept of instrument is introduced there. Next, we define the concept of system of measurement correlations and that of measuring process. The former is the exact counterpart of instrument ...

Blunted affect, also referred to as emotional blunting, is a prominent symptom of schizophrenia. Patients with blunted affect have difficulty in expressing their emotions. The work of Abrams and Taylor and their development of the Rating Scale for Emotional Blunting in the late 1970's was an early indicator that blunted affect could indeed be assessed reliably. Since then, several new instrumen...
