Alteración de la fertilidad del suelo por el cambio climático  su efecto en la productividad de maíz y trigo bajo riego
Provedor de dados: 32
Autores: Herrera Gómez, Sergio Santiago.
Se ha desarrollado la metodología de estimación de alteración de algunas  propiedades y un índice integral de fertilidad de los suelos irrigados de México  atribuible al cambio climático global durante el siglo XXI. Esta metodología fue  aplicada para evaluar la vulnerabilidad de la productividad de los cultivos de maíz de  grano y trigo bajo riego en algunos distritos de riego de referencia del país ubicados  en diferentes zonas climáticas. Los resultados de la investigación señalan que la  sensibilidad de los suelos agrícolas bajo riego en México, al cambio climático, es  mucho menor que los suelos de temporal y vírgenes y no afecta significativamente la  vulnerabilidad de los cultivos de maíz y trigo bajo riego. Por lo general, los valores de  cambio de...

A REVIEW ON SISAL FIBER REINFORCED POLYMER COMPOSITES
Provedor de dados: 91
Autores: Joseph,Kuruvilla; Tolêdo Filho,Romildo Dias; James,Beena; Thomas,Sabu; Carvalho,Laura Hecker de.
ABSTRACT The global demand for wood as a building material is steadily growing, while the availability of this natural resource is diminishing. This situation has led to the development of alternative materials. Of the various synthetic materials that have been explored and advocated, polymer composites claim a major participation as building materials. There has been a growing interest in utilizing natural fibres as reinforcement in polymer composite for making low cost construction materials in recent years. Natural fibres are prospective reinforcing materials and their use until now has been more traditional than technical. They have long served many useful purposes but the application of the material technology for the utilization of natural fibres as...

Some quality characteristics of Gari as influenced by roasting methods
Provedor de dados: 111
Autores: Sanni, Lateef Ayodele; Odukogbe, Oluwatobi Olalekan; Faborode, Michael Oladimeji.
In this study, the effect of mechanized roasting on some properties and proximate composition of gari was investigated. Pulverized and sifted cassava mash was roasted by conductive rotary drying and traditional manual method.  Products from the two methods were compared using the students’ t-test and the results showed that bulk density and coefficient of uniformity of mechanically roasted gari of  469.89 kg/m3 and 2.89, respectively, were not significantly different (p˃0.05) from those of manually roasted gari of 472.74 kg/m3 and 2.53, respectively.  The swelling indices of the two products were 3.29 and 3.69, respectively, which were significantly different (p ˂ 0.05) and greater than the recommended swelling index of 3.0 required for high quality gari....

Purification and some properties of pectinesterase from potato (Solanum tuberosum L.) alpha cultivar
Provedor de dados: 52
Autores: Montañez Sáenz,Julio; Téllez,Alejandro; de la Garza,Heliodoro; de la Luz Reyes,María; Contreras-Esquivel,Juan Carlos; Aguilar,Cristóbal Noé.
Pectinesterase was extracted from potato alpha cultivar, purified and partially characterized The used protocol resulted in a 58.8-fold purification (51 850.2 units/mg protein) with 15.5% recovery of pectinesterase activity. The purified enzyme had a molecular weight of 27 kDa and its isoelectric point was around 4.5 with pH and temperature optima of 8.0 and 60°C, respectively. The purified enzyme had a single symmetric peak of specific activity after chromatographic steps. The homogeneity of the purified pectinesterase was confirmed by gel filtration and polyacrylamide electrophoresis gel.

Purification and properties of asparaginase from the testa of immature seeds of pea (Pisum sativum L.)
Provedor de dados: 52
Autores: Chagas,Eliana P.; Sodek,Ladaslav.
A K+-dependent asparaginase (E.C. 3.5.1.1.) was purified 1328-fold from the testas of immature pea seeds (Pisum sativum L., var. Bolero) and characterized. Antibodies raised against purified asparaginase cross-reacted with the putative asparaginase band in Western blot analyses of semi-purified extracts. However, for crude extracts of pea testas, a cross-reaction was obtained with at least four protein bands, one of which was asparaginase protein. Affinity-purified antibodies to the four strongest bands of crude extracts were fairly specific for the bands from which they were purified, suggesting a mixture of specific antibodies. The Mr of asparaginase was 69,000 by Sephacryl S200 chromatography and also by mobility on native PAGE relative to BSA. There...

ABSTRACT: This paper aimed to evaluate the technological properties of particleboards produced with particles of unconventional species, bamboo of the species Phyllostachys edulis, and of the genus traditionally used by the sector for the production of the particulate panels in Brazil, Pinus spp.The bamboo splints of 3 years old were collected in Frei Rogério, Santa Catarina, being transformed into particles in a mill hammer, while the particles of Pinus spp. were collected from the industrial process of MDP production in Bonet Madeiras e Papéis Ltda Company in Santa Cecília, Santa Catarina. The company used eight-year-old logs of P. taeda and P. elliottii from the thinning process, without distinction of the species. The experiment was composed of five...
