In this paper preliminary mineralogical characterization of hematite from Alinci is presented. Several crystals were collected for research. The straight-forward identification the studied mineral sam-ples was enabled by optical microscope, SEM-EDS, ICP-MS and XRPD methods. use these methods showed that they are very useful rapid analysis contributing important analytical information. With esta...

Nos centramos en la zona originaria del vino licoroso dulce conocido como Pajarete (Paxarete los textos antiguos). Su nombre procede de un peñón situado el término municipal Villamartín, Sierra norte provincia Cádiz (Andalucía, España), que se encuentra coronado por una fortaleza origen musulmán. El pago Pajarete, prácticamente desaparecido entre última década s. XIX y Primera Guerra Mundial, d...

Communal rangelands in South Africa are generally perceived as overgrazed owing to complexities their histories and collective utilisation which often leads improper management. A suitable solution has not been found land management policies because local people’s contexts indigenous knowledge ignored. Hence, this paper is aimed at (i) assessing the role can play communal rangeland management, ...

Fruit mixed pulp has the objective of improving nutritional and sensorial characteristics, as well development new flavours aromas. Different methods drying (e.g., spray-drying, spouted bed drying, freeze-drying) can influence quality final product. The this study was to select method that enables production acerola-ceriguela (ACMP) with higher quality. For selection, powder pulps were evaluate...

This study aimed to evaluate the effect of five cooking methods (steam, grill, oven, frying and microwave) on farm-raised rainbow trout's sensory acceptability, physicochemical characteristics, nutritional value. A survey was conducted with 307 consumers create a marinade made salt, garlic, cumin pepper. The fillets marinated in this mixture were cooked, photographs taken determine their profil...

We isolated 15 mutants of Pseudomonas aeruginosa PAO which were defective in the formation of certain extracellular proteins, such as elastase, staphylolytic enzyme, and lipase ( Xcp mutants). The mutations were mapped on the chromosome by conjugation and transduction. The locations were xcp -1 near 0', with the gene order cys-59- xcp -1- proB , and loci xcp -2, xcp -3, and xcp -31 at 35', with...

Here, we describe for the first time the Crc (catabolite repression control) protein from the soil bacterium Acinetobacter baylyi. Expression of A. baylyi crc varied according to the growth conditions. A strain with a disrupted crc gene showed the same growth as the wild type on a number of carbon sources. Carbon catabolite repression by acetate and succinate of protocatechuate 3,4-dioxygenase,...

The sorting task is popular with sensory scientists because it provides rapid sensory profiles, even when product sets are complex or fatiguing. However, these sensory profiles generally cannot identify which sensory properties are driving subjects' perception of product similarities or differences—a critical task for the sensory analyst. This paper presents DISTATIS with Barycentric Text Proje...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. This tutorial review describes recent progress in modeling the active sites of carboxylate-rich non-heme diiron enzymes that activate dioxygen to carry out several key reactions in nature. The chemistry of soluble methane monooxygenase, which cata-lyzes the selective oxidation ...

A bacterial strain, which based on the sequences of its 16S rRNA, gyrB, catA, and qsdA genes, was identified as a Rhodococcus sp. closely related to Rhodococcus erythropolis, was isolated from soil by enrichment on the Pseudomonas quinolone signal [PQS; 2-heptyl-3-hydroxy-4(1H)-quinolone], a quorum sensing signal employed by the opportunistic pathogen Pseudomonas aeruginosa. The isolate, termed...
