In an previous research project a new type of greenhouse with an integrated concentrated photovoltaic system (CPV) was developed which has an integrated filter for reflecting the near infrared radiation (NIR) to the greenhouse and exploiting this radiation in a solar energy system. The performance of …

Throughout the world greenhouse horticulture is expanding and intensifying. The expansion is driven by the much higher production levels that are achieved in greenhouses compared to open fields. This provides increased income for farmers and a positive effect on rural development. Intensification is …

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 …

It is said that environmental problems are research dependent. Science is in these cases needed to identify a phenomenon such as climate change. New technologies can be characterized both by scientific uncertainties and research dependence (Yearley, 1996). An example of this is the case of biofuels. …

A new awareness program is needed to learn the women of Prime Trust's Self-Help Groups more about healthy nutrition for children. The following main question is formulated: What is an effective nutrition awareness program for mothers in Self- Help Groups in Puducherry to prevent undernutrition in young …

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. …

In 1949 the People's Republic of China emerged from a civil war with communist Mao Zedong as its victor. During the peak of Mao's rule China was completely isolated from the world. In the 1960's China lost the support of the Soviet Union due to failed policies such as the Great Leap Forward and various …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

Ghrelin, a peptide predominantly produced by the stomach [1], appears to play an important role in the regulation of food intake. Intravenous infusion of ghrelin stimulates food intake and enhances appetite in humans [2]. In addition, plasma ghrelin concentrations rise gradually before a meal and decrease …

Optimization routines for battery, supercap and fuel cell stack in a fuel cell based propulsion system face two problems: the tendency to cycle beating and the necessity to maintain identical amounts of stored energy in battery and supercap at the start and end of the driving cycle used in the simulation. …
