Valenciano, Martha Del C. Mesa;Freire, Wesley J.;
Engenharia Agrícola , 2004, DOI: 10.1590/S0100-69162004000300001
Abstract: this work was done with the objective of studying some physical and mechanical characteristics of the sugarcane bagasse ash added to a soil-cement mixture, in order to obtain an alternative construction material. the sugarcane bagasse ash pre-treatment included both sieving and grinding, before mixing with soil and cement. different proportions of cement-ash were tested by determining its standard consistence and its compressive resistance at 7 and 28 days age. the various treatments were subsequently applied to the specimens molded with different soil-cement-ash mixtures which in turns were submitted to compaction, unconfined compression and water absorption laboratory tests. the results showed that it is possible to replace up to 20% of portland cement by sugarcane bagasse ash without any damage to the mixture's compressive strength.

Abstract: current evidence indicates that human papillomavirus (hpv) can be transmitted both sexually and nonsexually. when the route of contagion is nonsexual, the mother appears to be the main transmitter of hpv to the newborn. several authors report detection of hpv dna in amniotic fluid, umbilical cord, placenta and fetal membranes, suggesting that the mother can infect the infant during pregnancy or childbirth. after transmission of virus from mother to newborn, clinical manifestations may appear at any stage in life, affecting mucous membranes, skin or both. when children present with oral papilloma, possible etiologies are direct contact, self-innoculation, sexual abuse or violence. however, when none of these causes are evident, family history should be investigated, especially if the mother manifested hpv infection during pregnancy. we present two cases of pediatric patients with clinical impression of oral papilloma without obvious cause. histopathology confirmed the diagnosis of hpv and route of transmission was established as mother-to-child, since mothers reported cervical hpv infection during pregnancy. furthermore, the childrens′ medical histories did not indicate any other route of contagion for the virus.
La narrativa biográfica: Opción metodológica para investigar la relación enfermera-personas viviendo con VIH/SIDA Biographical narrative: A methodological alternative to know more about the relation nurse-patient, living with HIV/AIDS
Yurian Lidia Rubiano Mesa,Alexander Ruiz Silva
Index de Enfermería , 2012,
Abstract: Ante la importancia de avanzar en el conocimiento de la relación de cuidado enfermera-paciente, y, en particular, sobre los elementos de carácter moral que la orientan y regulan, este artículo analiza, a partir de algunos referentes teóricos, la pertinencia del paradigma cualitativo -con enfoque narrativo biográfico- para estudiar los valores, los sentimientos y las acciones morales que articulan la relación entre enfermeras y personas que viven con Virus de Inmunodeficiencia Adquirido-Síndrome de Inmunodeficiencia Adquirida. Being so fundamental to advance in the knowledge of the relation of care nurse-patient, and, particularly, on the moral aspects that guide and regulate such a relation, this article analyzes, based on some theoretical models, the relevance of the qualitative paradigm -with a narrative biographical approach- to study the values, feelings and moral actions that constitute the relation between nurses and persons who live with Human Immunodeficiency Virus or Acquired Immunodeficiency Syndrome.
International Trade and Unemployment in Less Developed Countries  [PDF]
Fernando Mesa
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25101
Abstract:

The main interest focus of this paper is the relation between international trade and the labour market, with an emphasis on the unemployment rate, and the allocation of workers among sectors. A general trade equilibrium model with three sectors is constructed for a less developed country. An informal and un-tradable sector is characterised by flexible wages, while the other two sectors are tradable, export and import sectors. The model imposes a binding minimum wage on unskilled labour and wage distortions on skilled labour. Comparative statics are used to analyse the effects on the labour market of an open economy, a rise in the minimum wage and a positive productivity shock in the export sector.

Differences between Judo, Taekwondo and Kung-fu Athletes in Sustained Attention and Impulse Control  [PDF]
Javier Sánchez-López, Thalía Fernández, Juan Silva-Pereyra, Juan Antonio Martínez Mesa
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.47086
Abstract:

Attention processes are essential in athletic performance. Competition in combat sports requires high levels of attention, concentration and self-control. The aim of this study was to determine the differences in attention test performance among three groups of athletes from different disciplines of martial arts (judo, taekwondo and kung-fu). Twenty athletes with at least one year of experience in their respective sport were included in the study. The Test of Variables of Attention (TOVA) was performed, and data for the standard and Z scores of the quarters, halves and totals of each variable were analysed. The kung-fu athletes showed better inhibition response than the judo and taekwondo athletes. Minor performance deterioration during the impulsivity test was identified in kung-fu athletes compared with taekwondo and judo athletes. Judo athletes showed higher variability in reaction times than kung-fu athletes. Our study suggests that kung-fu training improved attention skills more than the other two disciplines. This effect can be explained by the athletes’ dedication to kung-fu training and the sport’s promotion of discipline, self-control and meditation.

La cachama blanca (Piaractus brachypomus), una especie potencial para el mejoramiento genético
Mesa-Granda,Martha N; Botero-Aguirre,Mónica C;
Revista Colombiana de Ciencias Pecuarias , 2007,
Abstract: in colombiacontinental pisciculturehas shown a significant growth (by 10% per year), because it is considered a good source of high quality protein for human beings.some researches have proven that cachama blanca (piaractus brachypomus) has several advantages because of its omnivorous behaviour, adaptation to different types of production, high docility, and good rate of food conversion among others. very few studies have been done regarding white cachama`s genetic parameters such as phenotypic characterization, genetic variability, inheritance coefficient and other genetic correlation about its most important productive characteristics. this knowledge would be extremely useful at the time of making decisions concerning the establishment of programs for genetic improvement, particularly considering characteristics that impair its commercial performance in the international trade market such as the number of intramuscular spines.
La cachama blanca (Piaractus brachypomus), una especie potencial para el mejoramiento genético White cachama (Piaractus brachypomus), a potencial species for genetic improvement
Martha N Mesa-Granda,Mónica C Botero-Aguirre
Revista Colombiana de Ciencias Pecuarias , 2007,
Abstract: En Colombia, la piscicultura continental es una alternativa de seguridad alimentaria, que tiene un alto incremento (10% anual), considerándose especies como Tilapia (Oreochromis sp) y cachama blanca (Piaractus brachypomus), los dos renglones más importantes para su desarrollo. Aunque la cachama blanca es una especie en la cual se han realizado investigaciones que han demostrado su potencial zootécnico, gracias a características tales como poseer hábitos omnívoros, adaptación a diferentes tipos de producciones, gran docilidad y buena tasa de conversión alimenticia, se han desarrollado pocos estudios acerca de parámetros genéticos, que involucren la caracterización fenotípica, variabilidad genética y fenotípica, coeficiente de heredabilidad, correlaciones genéticas de sus características productivas más importantes; estos aportarían información para la toma de decisiones en el establecimiento de programas de mejoramiento genético, especialmente en características que limitan su desempe o comercial en el mercado internacional, como es la de ‘número de espinas intramusculares’ (EIMT). In Colombia continental pisciculturehas shown a significant growth (by 10% per year), because it is considered a good source of high quality protein for human beings. Some researches have proven that cachama blanca (Piaractus brachypomus) has several advantages because of its omnivorous behaviour, adaptation to different types of production, high docility, and good rate of food conversion among others. Very few studies have been done regarding white cachama`s genetic parameters such as phenotypic characterization, genetic variability, inheritance coefficient and other genetic correlation about its most important productive characteristics. This knowledge would be extremely useful at the time of making decisions concerning the establishment of programs for genetic improvement, particularly considering characteristics that impair its commercial performance in the international trade market such as the number of intramuscular spines.
