Chondrocytes are the living cells in articular cartilage (AC). They synthesize and maintain the extracellular matrix. Their activity is regulated by the interplay of genetic and environmental factors, such as soluble mediators, extracellular matrix composition, and mechanical factors. The mechanical environment of the chondrocytes has a significant influence on the health of the joint. In past ...

Two hundred thirty-six students in 12th-grade physics classes took part in a quasiexperimental study comparing homogeneous and heterogeneous grouping in a jigsaw classroom. Students were assigned to expert groups according to their prior topic knowledge. Students showed higher intrinsic motivation, activated deeper level processing strategies, and performed better on their expert topic when wor...

Heterogeneous information systems are today inevitable for historical and technical reasons. Data is typically maintained on heterogeneous hardware and software platforms and a migration of the legacy systems to a homogeneous environment is not feasible due to high costs and the loss of available functionality. Between existing databases there are global integrity constraints that have to consi...

In the present research, 4, 4'-biphenol was used as a homogeneous mediator for determining cysteine (CySH) on a Glassy Carbon Electrode (GCE). To describe the electrochemical properties of 4,4'-biphenol and to examine its electrocatalytic impacts on cysteine oxidation, both Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) were employed. Our findings revealed that 4,4'-biphenol could s...

In this paper we present a system for data integration on the web, where an XML-based mediator plays a key role providing a homogeneous view of different data sources. One novelty of our approach is that we also propose solutions for the problems of generation and maintenance of mediators. Observe that, in dynamic environments, such as the Web, individual data sources may change not only their ...

Take a breath: An oxygen-tolerant hydrogenase can be employed with a dye in a photocatalytic scheme for the generation of H2 . The homogeneous system does not require a redox mediator and visible-light irradiation yields high amounts of H2 even in the presence of air.

Query evaluation strategies in traditional databases do not consider possible data inaccuracy and vagueness of predicates. However, measurement considerations and data quality are inherent components of geographic information. The purpose of this work is to explore query evaluation in distributed spatial information mediation system that takes into account different accuracy characteristics of ...
