A colorimetric mixed pH dye-based indicator to real-time monitoring rancidity reaction of infant milk powder formula is described. Milk powder stored in 30, 40, and 50°C was analyzed in terms of peroxide value (PV), moisture content, volatile compounds and sensory score. In addition, moisture sorption isotherms of infant milk powder formula were assessed at various temperatures including 30, 40...

The original study in three Pennsylvania houses found that operation of active soil depressurization (ASD) radon control systems caused modest reductions in basement moisture levels. Additional, supplemental analysis has been conducted on the relationship between basement air and outdoor air moisture, and on the movement of airborne sources of basement air moisture under the influence of ASD sy...

To better understand the effects of biological soil crusts (BSCs) on soil moisture and wind erosion and study the necessity and feasibility of disturbance of BSCs in the Mu Us sandland, the effects of four treatments, including moss-dominated crusts alone, Artemisia ordosica alone, bare sand, and Artemisia ordosica combined with moss-dominated crusts, on rainwater infiltration, soil moisture, a...

Biomass, mainly in the form of wood, is the oldest form of energy used by humans. Gasification is a process of conversion of solid carbonaceous fuel into combustible gas by partial combustion. In the present study, a model developed by us in our earlier study is used for predicting the steady-state composition and rate of reaction profiles for the reduction zone of the downdraft biomass gasifie...

UNLABELLED The public health risk and economic impact of dampness and mold exposures was assessed using current asthma as a health endpoint. Individual risk of current asthma from exposure to dampness and mold in homes from W.J. Fisk, Q. Lei-Gomez & M.J. Mendell [(2007) Indoor Air, [corrected] 17, 284-296], and [corrected] asthma risks calculated from additional studies that reported the preval...

Competition and facilitation are both considered major factors affecting the structure of plant assemblages, yet few studies have quantified positive, negative, and net effects simultaneously. In this study, we investigated the positive, negative, and net effects of tree saplings on the encroachment of two tree species, Douglas fir (Pseudotsuga menziesii) and tanoak (Lithocarpus densiflora), in...

This study was designed to examine the characteristics of sawdust and cocopeat bedding materials, including physicochemical properties (Exp. I) and on-farm trial (Exp. II). In Exp. I, the proportion of particle size was in the order of sawdust> cocopeat India>cocopeat Vietnam (p<0.05), and cocopeat contained higher proportion of small particles (250 μm+below 250 μm) than sawdust, causing a dust...

In this study, we determined using NIRS the heritability percentage of amylose, protein, and moisture content in polished and unpolished rice in a CNDH population derived from a cross between Cheongcheong and Nagdong rice varieties. The results revealed a higher heritability percentage for the amylose content and compromised heritability for protein and moisture contents. We also conducted QTL ...

China is a country seriously suffering from the lack of water resource, especially the north of China (a dense area) where there are more agricultural production than other places in China. Therefore, some have become most important problems which should be settled down right now for precision agriculture: saving the water of agriculture, optimizing the water for cropland as well as making use ...

The decomposition of organic matter is a major biogeochemical process because of its effect on ecosystem productivity and its implications on climate change. Temperature and moisture are two variables that have a tremendous influence on microbial decomposition. Decomposition is also influenced by substrate type, in which higher quality substrates often have greater decomposition than lower qual...
