The exposure of CIGS solar cells to different electrical biases in a damp-heat illumination environment

Two hybrid degradation setups, allowing exposure of solar cells and modules to elevated temperatures and humidity as well as illumination have been built. CIGS solar cells were placed in the degradation setups, allowing real time monitoring of their electrical properties. Under open circuit conditions, the efficiency of alkali-rich CIGS solar...

Systeemintegratie en flexibiliteit: De veranderende mix van fossiele en hernieuwbare bronnen in de Nederlandse energievoorziening

This study explores particularly the options for more flexibility at the supply side of the electricity system, with special interest to the role of biomass in preservation, flexibility and integration of the energy system as a whole. In addition, the study analyses the implications of a growing need for flexibility for (i) the reliability and...

Electronic Vehicle Identification Architecture and Proof of Concept

An architecture and a proof of concept for Electronic Vehicle Identification have beendeveloped. The system has been successfully tested in a pilot with 23 participants over a period of three months and a total distance of 75.000 km travelled. The architecture consists of a functional definition, a security framework and a design for the...

Extracellular matrix components and regulators in the airway smooth muscle in asthma

There is an intimate relationship between the extracellular matrix (ECM) and smooth muscle cells within the airways. Few studies have comprehensively assessed the composition of different ECM components and its regulators within the airway smooth muscle (ASM) in asthma. With the aid of image analysis, the fractional areas of total collagen and...

Collagen degradation in the abdominal aneurysm: A conspiracy of matrix metalloproteinase and cysteine collagenases

Growth and rupture of abdominal aortic aneurysms (AAAs) result from increased collagen turnover. Collagen turnover critically depends on specific collagenases that cleave the triple helical region of fibrillar collagen. As yet, the collagenases responsible for collagen degradation in AAAs have not been identified. Increased type I collagen...

Cathepsin K is the principal protease in giant cell tumor of bone

Giant cell tumor (GCT) of bone is a neoplasm of bone characterized by a localized osteolytic lesion. The nature of GCT is an enigma and the cell type(s) and protease(s) responsible for the extensive localized clinicoradiological osteolysis remain unresolved. We evaluated protease expression and cellular distribution of the proteolytic machinery...
