Snowmelt sensitivity to radiation in the urban environment

Despite having the same snowmelt processes, snowpacks in urban environments experience a range of conditions different from those of rural areas. Melt is intensified at some sites due to greater radiative energy. Shading, however, can reduce radiation and melt at other sites. Changes to the radiation balance and snowpack processes have been investigated. A physical snowpack model was developed and

Measuring cancer prevalence in Europe: the EUROPREVAL project

Cancer prevalence is the proportion of individuals in a population who at some stage during their lifetime have been diagnosed with cancer, irrespective of the date of diagnosis. Cancer prevalence statistics have generally been provided by a limited number of well established cancer registries that have been in existence for several decades. The advent of systematic follow-up of life status of inc

LICS - Language for Implementation of Control Systems

This report describes a language and an interactive environment, called LICS, for implementation of control systems and dynamic modelling. It used graphics for representation of the structural properties: hierarchical decomposition, interconnection structure, and structure of the interfaces. The decomposition and interconnection structures are described by block diagrams. Low level modules are des

The REAL process - a process for recycling sludge from water works

In order to produce drinking water, coagulants - such as aluminium salts - are widely used for precipitation and separation of impurities from raw water. The residual from the process is sludge, which presents a disposal problem. The REAL process is a method for recycling the aluminium from the sludge. In a first step, the aluminium hydroxide is dissolved in sulphuric acid. In a second step, an ul

Evaluating Motivational Factors Involved at Different Stages in an IS Outsourcing Decision Process

This study evaluates factors involved at different stages in an IS outsourcing decision process. From a theoretical perspective, the motivation for IS outsourcing is often described as a result of three factors: cost reduction, access to technological expertise and focus on core competence. The aim of this paper is to evaluate motivational factors in an outsourcing decision process. The study uses

Enterolactone and breast cancer: methodological issues may contribute to conflicting results in observational studies.

Lignans found in plant foods are converted by the intestinal microflora to enterolignans. The structure of enterolignans is similar to that of estrogens, which has inspired researchers to examine a potential protective association in relation to health outcomes. Numerous epidemiological studies have measured concentration of enterolignans, mainly enterolactone, in blood or urine as a biomarker of

Follower-Power: A follower-centric approach to the social construction of prophetic leadership

This article addresses the follower-centric examination of the social construction of prophetic leadership roles. The central questions are: In what ways can key follower figures potentially exert independent agency and influence within the charismatic relationship?; What role might they play in the establishment and maintenance of the social construction of prophetic leadership roles? To these en

Measurement-based modeling of vehicle-to-vehicle MIMO channels

Vehicle-to-vehicle (VTV) communications are of interest for applications within traffic safety and congestion avoidance, but the development of suitable communications systems requires accurate models for the VTV propagation channel. This paper presents a new wideband MIMO (multipleinput- multiple-output) channel model for VTV channels based on extensive MIMO channel measurements performed at 5.2
