The aim of this work was to find the most useful inorganic nitrogen source to enable Leucopaxillus giganteus to become a more nutritious mushroom, regarding organic acid and phenolic composition and total alkaloids content. For these, the influence of NH 4NO 3,NaNO 2, KNO 3,, and (NH 4) 2HPO 4 on the organic acid production was determined by HPLC-UV and total alkaloid content was assessed by a ...

Seeding nanoparticles in molten salts has been shown recently as a promising way to improve their thermo-physical properties. The prospect of such technology is of interest to both academic and industrial sectors in order to enhance the specific heat capacity of molten salt. The latter is used in concentrated solar power plants as both heat transfer fluid and sensible storage. This work explore...

One of the most dif ficult problems in the first stages of automatic speech recognition (ASR) is the identification of consonantal place of articulation (CPA). It is kno wn that the acoustic correlates for CPA reside largely in the pattern of formant transitions preceding v ocal tract closure and follo wing release, b ut common speech preprocessing techniques make only a limited attempt to capt...

We present an alignment-based method for estimating robot position and orientation from a single mountain image and digital elevation map. Robot pose estimation is achieved even without any initial position or orien tation parameter estimate and requires only that the robot's camera height abo veground be kno wnbeforehand. It is also robust to partial occlusion. Using mountain peaks as features...

Protection of ascorbic acid (AA) (vitamin C) from Cu(II)-catalyzed autoxidation is an important aspect of antioxidant chemistry. The autoxidation of AA in the absence and presence of Cu(II) ions was investigated in aerated solution at room temperature and I = 0.1 ionic strength (KNO(3)); the effects of three different flavonoids of similar structure (quercetin, morin and catechin) and their mix...

The response of net O(2) exchange to light intensity by intact Anacystis nidulans cells in the presence of saturating NaHCO(3) concentrations followed a curve with an inflection near the light-compensation point. Addition of either KNO(3) or NH(4)Cl stimulated O(2) uptake in the dark and at light intensities below the light-compensation point. This resulted in steeper slopes of the curve calcul...

Trie orientationaly disordered phase of a relatively large system of potassium perchlorate is simulated on a massively parallel computer with strict SIMD architecture. Crystallographic results are compared with kno~vn diffraction data. Correlation densities of orientational and translational variables are computed showing orientation-translation coupling of trie perchlorate ions, and coupling b...
