For fast detection of inorganic phosphorus fractions and their phosphorus contents in soil, a method employing near-infrared spectroscopy (NIRS) combined with partial least squares (PLS) and least squares support vector machine (LS-SVM) was proposed. Fifty soil samples for each of iron phosphate, magnesium phosphate, calcium phosphate and aluminum phosphate, with application rates of phosphate ...

geothermal investors need to be confident with the methods and results of exploration programs. also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

An ecologically sound approach to the problem of brush encroachment onto Israeli rangeland might be their utilization by goats, but better knowledge of the feeding selectivity and ability of goats to thrive in encroached areas is required to devise viable production systems. Direct observation of bites could provide precise and accurate estimates of diet selection, but construction of a suffici...

Currently, common optical techniques to measure tissue oxygen saturation (StO 2 ) include time domain (TD), frequency (FD), and continuous wave (CW) near-infrared spectroscopy (NIRS). While TD- FD-NIRS can provide absolute hemoglobin concentration, these systems are often complex expensive. CW-N...

Near infrared spectroscopy (NIRS) is a noninvasive optical technology that relies on the relative transparency of biological tissues to near infrared light (700-900 nm) to determine tissue oxygenation. Oxy and deoxy hemoglobin and cytochrome aa3 possess distinct absorption characteristics in the near infrared spectrum. By monitoring absorption at wavelengths where oxyand deoxyhemoglobin and cyt...

Penentuan karakteristik dan konsentrasi unsur hara tanah perlu dilakukan metode analisa untuk perlakuan lahan serta ketepatan dosis jenis pemupukan dalam optimalisasi produktivitas tanaman. Metode alternatif analisis kandungan sampel secara cepat, efektif, ramah lingkungan, tidak merusak dapat menggunakan near infrared spectroscopy (NIRS). Sampel yang digunakan berasal dari Laboratorium Tanah, ...

The purpose of this study was to cross-validate measurements of skeletal muscle oxidative capacity made with near-infrared spectroscopy (NIRS) measurements to those made with phosphorus magnetic resonance spectroscopy ((31)P-MRS). Sixteen young (age = 22.5 ± 3.0 yr), healthy individuals were tested with both (31)P-MRS and NIRS during a single testing session. The recovery rate of phosphocreatin...

Near-infrared spectroscopy (NIRS) and mid-infrared spectroscopy (MIRS) have been used for quantitative and/or qualitative analysis of a wide range of materials. The objective of this study was to investigate the potential of MIRS and NIRS for following the degradation of bio-based food utensils during composting. Polylactide (PLA)-based forks lost 34% of their initial mass and were reduced to s...

Data about diet and digestion process of cattle are important for the fine-tuning from an environmental point view. Given capacity near-infrared reflectance spectroscopy (NIRS) to provide easily, quickly cheap data its ability in predicting dietary faecal chemical composition, fibre-bound N total-tract apparent digestibility (ttaD) beef were tested. The ttaD was estimated using undigestible neu...
