El disco intervertebral es una estructura fibrocartilosa localizada entre las vértebras de la columna y consiste de un núcleo pulposo, un anillo fibroso y una placa de cartílago. El disco ayuda a dar movilidad y curvatura a la columna, sirve como disipador de impactos y colabora en la transmisión de carga del torso. Con el tiempo e historial de carga, estas funciones se ven mermadas, comprometiendo otras funciones del disco y de carácter mecan...

La utilización de los métodos problémicos en la enseñanza de la Física en el primer año de la Educación Técnica y Profesional (ETP) está dirigida a favorecer los conocimientos de esta asignatura en los estudiantes, situación que se econtraba frustrada. A raíz de la anterior problemática se pudo constatar, en el plano teórico y práctico, algunas insuficiencias que permitieron al autor enfrentar objetivamente la labor educativa, por lo que a tra...

La continua destrucción de hábitats, el crecimiento poblacional y la falta de aplicación de leyes ambientales, entre otros, convierten a los bosques tropicales en uno de los ecosistemas más vulnerables del planeta. La Restauración del Capital Natural se considera una alternativa que promueve la recuperación parcial o total de los ecosistemas, para de esta forma mejorar el bienestar de la población. Se centra en revertir las tendencias de un ap...

El libro describe una verdadera curiosidad sistémica y constituye una teoría que explica la obligatoriedad de un modelo que, impuesto por la práctica social, resulta incompatible con el que prescribe la ley formal, mostrando la dicotomía dada en el sector público sindical argentino, en el cual mientras la ley formal concibió un sistema (de unidad promocionada) los usos y costumbres que se trasuntaron en el plano fáctico, impusieron un sistema ...

The onset of Green Revolution in India, undoubtedly solved the food crisis, but was accompanied by the chemical pesticides syndrome. With the ever increasing awareness about the harmful effects of chemical pesticides on man and his environment, the immediate need for sustainable eco friendly pest management has been felt very strongly, providing an impetus for research and development of microbial insecticides for obvious reasons. A growing pr...

Generally, we see the solutions with restricting in finite range, we use to find solutions for Diophantine equations. However, in my work, I have discussed and introduced a novel approach to solve Diophantine equations. Also, without restricting the solutions range and set (N or Z or Q or R or C), we can find solutions infinitely in some new Diophantine equations, which I call as, Dio-Gandhi equations. Precisely, we can find solutions in any r...

The rationale for this study emerged from a realization that conventional instructional design approaches for introducing Calculus concepts, based on the logical sequencing and structuring of the concepts, did not adequately attend to or address students' ways of thinking. The instructional design theory of Realistic Mathematics Education (RME) offered a promising approach for designing learning sequences based on actual investigations of the ...

In this book, we investigate to compare average return of value and growth stock during 8 years from 2001 until 2008 in Tehran Stock Exchange. Samples include 91 firms in order to classify value and growth we used B/M. data mining for beginning book value and ending market value of stock performed. Three classes were separate. Highest and lowest classes were chosen and middle class was omitted. Average return of highest group (value stock) and...

The banking industry is one of the most active markets for mergers and acquisitions. Several studies show that mergers and acquisitions based on operating performance approach turn out successfully while some show unsuccessfully by not showing performance gains. There are several reasons and this depends on the choice of accounting method. In this study efforts are made to examine the operating performance of bank's mergers and acquisitions ov...

The problem of Protein Structure Prediction (PSP) is one of the principal topics in Bioinformatics. Multiple approaches have been developed in order to predict the protein structure of a protein. Determining the three dimensional structure of proteins is necessary to understand the functions of molecular protein level. An useful, and commonly used, representation for protein 3D structure is the protein contact map, which represents binary prox...

This book titled:"Cost Benefit Analysis of Certified Cocoa Production in Ondo State, Nigeria" centres on the cost and returns associated with the production of certified cocoa in Nigeria. In addition, the book contains information on comparative analysis of production of conventional and certified cocoa in addition to the benefits derivable from the production of certified cocoa. Some basic concepts associated with cocoa certification such as:...

Vegetables are in abundance shortly after the rainy season but become scarce during the dry season during which cultivated types are used. Some eventually find their way to urban markets. One of the most commonly consumed leafy vegetables in Nigeria is Telfairia occidentalis, which is employed both for culinary and medicinal purposes.The main protective action of vegetables has been attributed to the antioxidants present in them. The oxidative...

Genetics is the study of heredity, the process by which characters are passed from parents to their offsprings, so that all offsprings resemble their parents. According to the concept of genetics, heredity is controlled by large number of genes that are located on chromosomes which are called Hereditary Vehicles. Chromosomes are composed of deoxyribo¬nucleic acid (DNA) and protein. Many diseases are a result of sudden heritable structural chan...

Hydroisomerisation of linear alkanes in the gasoline feed to their corresponding isomers is recently considered the most suitable petrol upgrading option, particularly due to environmental and economic concerns. Several catalysts have so far been reported to be associated with activity and stability challenges, the book therefore covers useful information based on most recent literature, on these catalysts and the prospects of metal(s) or sulp...
