摘要： Soil organisms undertake every major ecosystem process, from primary production to decomposition to carbon sequestration, and those processes they catalyze have a bearing on the management of issues from agriculture to global climate change. Nonetheless, until recently, research to measure the dynamics of microscopic organisms living belowground has largely been limited to infrequent field sampling and laboratory extrapolation. Now, however, new sensor technologies can measure and monitor soil organisms and processes at rapid and continuous temporal scales. In this article, we describe these technologies and how they can be arrayed for an integrated view of soil dynamics.

关键词： sensor   light backscatter   coagulation   syneresis   moisture content control   yield   whey fat  

摘要： The objective of this study was to investigate a novel light backscatter sensor, with a large field of view relative to curd size, for continuous on-line monitoring of coagulation and syneresis to improve curd moisture content control. A three-level, central composite design was employed to study the effects of temperature, cutting time, and CaCl2 addition on cheese making parameters. The sensor signal was recorded and analyzed. The light backscatter ratio followed a sigmoid increase during coagulation and decreased asymptotically after gel cutting. Curd yield and curd moisture content were predicted from the time to the maximum slope of the first derivative of the light backscatter ratio during coagulation and the decrease in the sensor response during syneresis. Whey fat was affected by coagulation kinetics and cutting time, suggesting curd rheological properties at cutting are dominant factors determining fat losses. The proposed technology shows potential for on-line monitoring of coagulation and syneresis. 2007 Elsevier Ltd. All rights reserved.

摘要： Metallothionein (MT) are a class of intracellular proteins possessing cysteme-rich and heavy metal-binding properties. They can be utilized as biomarkers for the detection and assessment of heavy metals in environmental pollution. This paper addresses the development of a sensor technique suitable for the determination of MT in the tissue samples of perches and their parasites. The work suggest a heavy metal biosensor based on interaction of heavy metals (lead(H), cadmium(H), copper(II) and silver(l)) with MT using adsorptive transfer stripping (AdTS) technique in combination with chronopotentiometric stripping analysis. The samples were investigated with various heavy metals (lead(H), cadmium(H), copper(H) and silver(l)), prior to sensor applications to understand the interaction between MT and the metals. The results obtained from this experiment clearly show that cadmium(II) had the highest affinity for MT followed by silver(l), copper(H) and lead(H). Based on these results, we attempted to quantify MT content with respect to content of a heavy metal in the samples of interest. The highest re-evaluated concentration of MT (495 ng/g of fresh weight) was determined in samples of Acanthocephalus anguillae. (c) 2007 Elsevier B.V. All rights reserved.
