Isothermal calorimetry and diffuse reflectance infrared DR–FTIR spectroscopy are combined to correlate evolutions of spectroscopic signatures with rates of chemical reactions as reflected in the rate of heat emitted during the first 38 h of cement hydration. Portland limestone cement mortar is employed and the analysis is repeated for two different mixing procedures. Intensive blender mixing with

Background and aims-Laser induced fluorescence (LIF) from colonic mucosa was measured in vivo with and without delta aminolevulinic acid (ALA) in an attempt to differentiate between neoplasia and non-neoplasia in real time during colonoscopy. Methods-Spectra from 32 adenomas, 68 normal sites, and 14 hyperplastic polyps in 41 patients were obtained with a point monitoring system. Twenty one of the

First laser spectroscopic investigations on atomic selenium are reported. Natural selenium was thermally dissociated in a quartz resonance cell keeping the background pressure of abundant selenium molecules low by differential heating. The 4p35s5S2 level was excited by frequency-tripled pulsed-dye laser radiation at 207 nm. From time-resolved recordings of the fluorescence decay at 216 nm a natura

INTRODUCTION: More knowledge is needed about structural factors in society that affect risky sexual behaviors. Educational institutions such as universities provide an opportune arena for interventions among young people. The aim of this study was to investigate the relationship between sociodemographic and religious factors and their impact on sexual behavior among university students in Uganda.

Pore and fiber-matrix theory can both be used to model the peritoneal and glomerular filtration barriers in an attempt to shed light on their differing structure-function relationships. The glomerular filtration barrier (GFB) is structurally more specialized, morphologically complex, and also highly dynamic; but paradoxically, because of its uniformity, it conforms more closely to the predictions

Different aspects of the integration of conventional control system and knowledge-based systems are discussed. Special requirements such as multiple forms of knowledge representation, support for model-based reasoning, and real-time operation are discussed. Three different forms of integration are described: interfaced systems, embedded systems, and totally integrated systems.

Presented at conference on NGO studies and anthropology, panel on elite NGOs and NGO elites. Abstract. The anticorruption NGO Transparency International was founded in 1993 by a former World Bank official and his network of ex-diplomats, lawyers, development consultants and businessmen. With headquarters in Berlin and affiliate organizations in 90 countries, it is truly one of the most successful

This paper focuses on the radio wave propagation through energy saving windows. These panes have a metallic shielding that keeps the heat inside the building during winter and outside during summer. Unfortunately, this covering also has an opaque behaviour at microwave frequencies. A design of energy saving window panes with high transmission at 900MHz and 1800MHz is presented. The high transmissi

During the last decade social media has become an increasingly common platform for political participation. However there is to date no research investigating the personality and/or incentive correlates of political participation on social media platforms. Some previous research has shown that extraversion is positively correlated to social media use (Correa et al, 2010), while other studies have

It is argued that we live in a post-industrial society with a transition from the production of goods to services. It is also said we live in a knowledge economy where creation, distribution, use and manipulation of information are significant activities (Dahlbom, 2003). The word industrial has a connotation of mass-production of products and, logically also industrial design has this connotation.

ad transport of dangerous goods is due to its inherent risk associated with a potential impact far higher than the small volumes might suggest, and has therefore been the target of numerous ITS-related initiatives. However, there are few indications of actual working ITS solutions for dangerous goods. In this paper we conduct an empirical investigation of past projects and research to analyze the
