[1] To increase our understanding of carbon (C) cycling and storage in soils, we used C to trace C from roots into four soil organic matter (SOM) fractions and the movement of soil microbes in arctic wet sedge and tussock tundra. For both tundra types, the proportion of C activity in the soil was 6% of the total C-CO2 taken up by plants at each of the four harvests conducted 1, 7, 21, and 68 da...

This paper discusses how a qualitative understanding on the physics of failure can lead to a theoretical derivation of effective features that are useful for condition monitoring of wet friction clutches. The physical relationships between the features and the mean coefficient of friction (COF) which can be seen as the representation of the degradation level of a wet friction clutch are theoret...

A small concentration of organic acid in carbon dioxide (CO2) storage formations and caprocks could significantly alter the wettability such into less water-wet conditions, decreasing CO2-storage potential containment security. Recent studies have attempted to infer influence on rock–CO2–brine systems by measuring advancing receding contact angles. However, no investigated contamination capacit...

mazafati date is a wet and semi-dried date fruit type with dark red to black color that has premier quality. because of its high moisture content, date fruits of this variety are very perishable at room temperature and therefore must be refrigerated during storage. in this study, effect of air temperature (50, 60, 70, 80 and 90 ˚c) and air flow rate (1, 1.5 and 2 m/s) in hot air drying of mazaf...

[1] Despite the importance of mountainous catchments for providing freshwater resources, especially in semi-arid regions, little is known about key hydrological processes such as mountain block recharge (MBR). Here we implement a data-based method informed by isotopic data to quantify MBR rates using recession flow analysis. We applied our hybrid method in a semi-arid sky island catchment in so...

The factors controlling seasonal rainfall interception loss are investigated by using a double-mass curve analysis, based on direct measurements of high-temporal resolution gross rainfall, throughfall and stemflow from 43 rainfall events that occurred in central Taiwan from April 2008 to April 2009. The canopy water storage capacity for the wet season was estimated to be 1.86 mm, about twice th...

This study was designed to determine if avulsed permanent incisors which have been kept dry for a period and then immersed in an isotonic solution prior to implantation have an increased healing rate. The permanent maxillary incisors of six beagle dogs were grouped by lot in six treatment classes so that each type of incisor was included in each class. After extraction, the teeth of a treatment...
