the potential of fourier transform near-infrared (ft-nir) spectroscopy technique was applied to determine moisture and soluble solids content of shahani date fruit. spectral acquisitions were carried out in reflectance mode using a ft-nir spectrophotometer in the range of 12000- 4000cm-1. three different preprocessing methods namely: multiplicative scatter correction (msc), first and second der...

(1) the secondary stage of freeze - drying, particularly the last day, is not important and i suggest the whole procedure is reduced to three days, the primary stage occupying two of these. (2) the mothod used obtains the satisfactory low level of residual moisture. resume (3) experiments on reconstitution with saline and distilled water show that distilled water is more satisfactory and i sugg...

OBJECTIVES This study evaluated the effects of intraradicular moisture on the pushout bond strength of a fibre post luted with several self-adhesive resin cements. MATERIALS AND METHODS ENDODONTICALLY TREATED ROOT CANALS WERE TREATED WITH ONE OF THREE LUTING CEMENTS: (1) RelyX U100, (2) Clearfil SA, and (3) G-Cem. Roots were then divided into four subgroups according to the moisture condition...

Standard maize starch was hydrothermally treated at residual moisture content (~12 %) by Instantaneous Controlled Pressure Drop for various pressure levels and processing times. In order to examine the homogeneity of the starch treatment, three thicknesses (1.5, 1 and 0.5 cm) were tested at 3 bar of steam pressure. For the three thicknesses, the temperature and the moisture content of starch we...

We investigated two approaches for large-scale analysis and prediction of the spatial distribution of soil properties in an agricultural landscape in the Canadian prairies. The first approach was based on the implementation of nine types of digital terrain models (DTMs) and regression analysis of soil and topographic data. The second approach used a concept of accumulation, transit, and dissipa...

PURPOSE We surveyed youths and denture wearers to evaluate the feeling of oral dryness. MATERIALS AND METHODS The survey was performed in 100 denture wearers (mean age, 66.2+/-8.6 years) who visited our department from June to October 2003. A similar survey was performed in 50 20-29 year-old persons (mean age, 25.6+/-2.4 years). Measurement of the height of the salivary moisture area, and det...

Leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. Determining drying characteristics of leather is vitally important so as to optimize the drying stage. This paper describes an analytical way for determination of the drying characteristics of leather. The model presented, is based on fundamental heat and mass tra...

This research presents the results of a series of stability studies on freeze-dried formulations of human growth hormone (hGH). Chemical decomposition via methionine oxidation and asparagine deamidation as well as irreversible aggregation are characterized by HPLC. Water sorption isotherms, DSC thermograms, and pulsed proton NMR data are also obtained. No glass transition temperatures are obser...
