This document presents the investigation of the costs of investing in a new transformer compared to the maintenance of an existing one. A detailed research of the different technical possibilities to maintain transformers has been conducted. Superconducting Magnetic Energy Storage (SMES) technology had …

Model calculations and the few data that are available show that over 100 L water condense yearly on each square meter of a greenhouse cover. It is known that the presence of condensate reduces light transmission. This effect is suppressed to some extent by adding film-forming (anti-drop) additives to …

The scope of this investigation is the development and testing of a new type of greenhouse with an integrated linear Fresnel lens, receiver module and an innovative system for tracking to exploiting all direct radiation in a solar energy system. …

A new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …

Although sustainability is often discussed solely in ecological terms, it cannot be disconnected from the way humans behave in their social environment. This article presents a theoretical approach toward sustainability that takes a human behavior and knowledge view on sustainability as a starting point. …

In dit hoofdstuk wordt ingegaan op de toepassing van vraagpatronenonderzoek als middel om formele en informele ondersteuning te verbinden. Hierbij wordt nadrukkelijk niet alleen gekeken naar zorg, maar ook naar meer brede vormen van ondersteunende activiteiten waar burgers van profiteren en in participeren. …

De noodzaak voor docentprofessionalisering is in dit tijdschrift al veelvuldig beschreven. Daarbij ligt het accent vaak op het individu. Maar juist collectieven zoals kenniskringen en lectorarten hebben een bijzonder vermogen om samen te leren. Het instellen van een kennisgemeenschap, zoals een Community …

Performance results are given of a new type of greenhouse, which combines reflection of near infrared radiation (NIR) with electrical power generation using hybrid photovoltaic cell/thermal collector modules. Besides the generation of electrical and thermal energy, the reflection of the NIR will result …
