Wheat straw was used to produce medium-density fiberboard (MDF). The chemical and physical characteristics of fractionated size-reduced wheat straw were investigated. The pH, pH-buffering capacity, ash, and silicon content increased as wheat straw particle size decreased. Ash of the finest…

For the first time for Mexican mycobiota the genus Cerinomyces Mar. is reported with the species C. lagerheimii(Pat.) McNabb. This species only have been found in Ecuador (type locality), Brasil, United States and Venezuela. A review of different specimens was…

The characteristics of enzymatic/mild acidolysis lignin (EMAL) isolated from moso bamboo were investigated using pyrolysis-gas chromato-graphy/mass spectrometry (Py-GC/MS). Pyrolysis temperature as a factor on products was studied, and the pyrolysis mechanism was inferred with respect to the dominating products. Research…

Nanoparticles are widely used in the papermaking industry as retention/ drainage aids, usually in conjunction with a high mass cationic polyelectrolyte such as cationic starch. However, little convincing knowledge of their role and mechanism in the wet-end system is yet…

Background: During preoperative preparation patients undergo investigations to detect asymptomatic diseases. The probability of finding significant abnormalities on such "routine" investigations is small, unnecessarily increasing costs of perioperative care. We evaluated current practices, compliance with guidelines and costs of preoperative…

En esta comunicación presentaremos el trabajo que estamos realizando, centrado en la creación de entornos que permitan la construcción conjunta del conocimiento mediante herramientas informáticas, en concreto la herramienta Knowledge Forum como elemento mediador en el proceso de discusión y…

Next generation sequence technologies (NGS) made possible to sequence entirely genomes in a fast way and low cost, from unicellular to complex organisms, like plants and mammals. These sequences can be assembled (i ) using a reference genome or by…

This article talks about Bioethics and new technologies perspectives in the de nominated Society of Knowledge. It formulates central topics lead to wards transition forwarding to new civilizations. It also points out questionings and suggests several hypothests about the future…

El hombre desde que nace empieza a aprender. Algunos conocimientos se adquieren sin percatarnos de ellos, otros necesitan esfuerzos y dedicación, algunos son estrictamente necesarios, otros no lo son tanto. El proceso de búsqueda de relaciones es un modo de…
