Revista en Ciencias del Movimiento Humano y Salud , 2011,
Abstract: Objetivo: Describir y analizar las modificaciones en la composición corporal, en las mujeres de mediana edad, después de realizar un programa de actividad física, basado en el aquaerobic, y un posterior periodo de desentrenamiento. Material y método: El grupo analizado estuvo integrado por diecisiete mujeres de Arroyo de San Serván (Badajoz), físicamente activas (habían realizado programas de gimnasia de mantenimiento, con una frecuencia de una a tres sesiones semanales, durante los últimos tres meses), con una edad media de 53,6 ± 9,1 a os. El programa se desarrolló con sesiones de sesenta minutos durante cinco días a la semana, por seis semanas, con un periodo de desentrenamiento de cuatro semanas. Se realizaron tres evaluaciones antropométricas: al iniciar el programa, al finalizar el mismo, tras el periodo de desentrenamiento. En cada medición, se determinaban la talla y el peso, seis pliegues cutáneos, cuatro perímetros corporales y tres diámetros óseos. El porcentaje de grasa fue obtenido a través de los datos arrojados en cuatro pliegues cutáneos (tricipital, subescapular, suprailíaco y abdominal) mediante la fórmula de Yuhasz, modificada por Faulkner (1968). Por su parte, el porcentaje muscular fue calculado, a partir del porcentaje de la masa total, menos el porcentaje óseo (Rocha, 1975), el porcentaje graso (Faulkner, 1968) y el porcentaje residual, a través de la ecuación de Wurch (Esparza, 1993), de los sujetos medidos, según la propuesta básica de Matiegka (modelo de los cuatro componentes). Resultados: después de realizar el programa, se observó un aumento significativo en el porcentaje muscular: 32.69 ± 2.69% vs. 33.44 ± 2.89% (p < 0.05), en el peso muscular: 23.45 ± 3.53 kg vs. 24.02 ± 3.33 kg (p <0.05), y un descenso significativo del componente graso reflejado, mediante el sumatorio de pliegues cutáneos: 193.66 ± 25.54 mm vs. 188.38 ± 25.67 mm (P <0,05), más específicamente, en el pliegue suprailíaco, 30.47 ± 8.49 mm vs. 28.00 ± 8.78 mm (p <0,05) Estas tendencias se mantuvieron durante el periodo de desentrenamiento, en el porcentaje muscular: 33.44 ± 2.89% vs. 34,25 ± 3,04% (p<0,01 con respecto a la inicial), en el peso muscular: 24.02 ± 3.33 kg vs 24,74 ± 3,64kg (p<0,01 con respecto a la inicial), el sumatorio de pliegues cutáneos: 188.38 ± 25.67 mm vs 183,41 ± 26,65 mm (p<0,05 con respecto a la inicial). Conclusiones: La participación en programas de aquaerobics de corta duración bajo las condiciones de este estudio provoca descensos del componente graso y aumentos significativos en el componente muscular, en las mujeres activas de
Classification of Malicious Distributed SELinux Activities

Journal of Computers , 2009, DOI: 10.4304/jcp.4.5.423-432
Abstract: This paper deals with the classification of malicious activities occurring on a network of SELinux hosts. SELinux system logs come from a high interaction distributed honeypot. An architecture is proposed to compute those events in order to assemble system sessions, such as malicious ones. Afterwards, recognition mechanisms are proposed to classify those activities. The paper presents the classification architecture using comprehensive examples. It is the first solution that supports SELinux sessions. In contrast with previous works, distributed sessions are better addressed using only SELinux logs. The results of experiments use real samples taken from our honeypot. A high performance architecture enables to compute a large amount of events captured during one year on our high interaction honeypot. Our approach enables the real-time reconstruction of system sessions. Moreover, sessions are compared to patterns in order to classify them according to specific attacks. The paper shows that the classification can be done in a linear time. An automatic recognition of new patterns is proposed.

Abstract: brazil is the world's largest sugarcane producer, so changes in sugarcane management in brazil can affect the environment to a great extent. during almost one century, studies were carried out in cropping systems involving pre-harvest burning of aerial sugarcane residues. nowadays the green trash management of sugarcane residues has become a common practice, although the effects are still poorly documented. the objective of this work was to compare topsoil carbon and nitrogen stocks, aggregation and bulk density in brazilian sugarcane plantations where aerial residues were either burned (cq) or left on the soil surface (sq) after harvest. the study was carried out in three plantations, one on a clayey soil (latossolo vermelho, lvdf, i.e. typic hapludox) and two on sandy soils (argissolo vermelho-amarelo, pvad, i.e. typic hapludult, and neossolo quartzarênico, rqo, i.e. quartzpsamment). on each plantation, the experimental design included six replications per treatment. after three crops, the accumulated aerial residue biomass in sq treatment amounted to 40 t ha-1 of dm from which 4.5 and 3.6 t ha-1 of dm (i.e. 11 and 9 %) were still present at the soil surface in lvdf and rqo, respectively. this represented 1.60 and 1.35 t ha-1 of c and 0.022 and 0.021 t ha-1 of n, respectively. as a result, soil carbon at a 0-20 cm depth increased by 6.3 and 4.7 t ha-1 in lvdf and rqo, respectively. over the three-year period, the rate of carbon sequestration in the litter and topsoil in the sq treatment was 2.63 and 2.02 t ha-1 yr-1 in lvdf and rqo, respectively. topsoil content of stable macroaggregates was also higher with sq than with cq: 814 vs. 693 g kg-1 in lvdf, and 516 vs, 420 g kg-1 in rqo, respectively. on the other hand, sq caused topsoil compaction (pvad and rqo) due to the mechanized harvest system. in the brazilian soils under study, green trash management of sugarcane residues improved the topsoil properties and promoted carbon and nitrogen sequestration in the litt
Defect evolution and interplay in n-type InN

Abstract: The nature and interplay of intrinsic point and extended defects in n-type Si-doped InN epilayers with free carrier concentrations up to 6.6x10E20cm-3 are studied using positron annihilation spectroscopy and transmission electron microscopy and compared to results from undoped irradiated films. In as-grown Si-doped samples, V_In-V_N complexes are the dominant III-sublattice related vacancy defects. Enhanced formation of larger V_In-mV_N clusters is observed at the interface, which speaks for high concentrations of additional V_N in the near-interface region and coincides with an increase in the density of screw and edge type dislocations in that area.
New standards for new poverties. Ecosystemic strategies and governance of the chain

Abstract: The impact and duration of the economic crisis we are experiencing is having a profound influence on the extended construction chain, it conditions the productive system, the system of products and services, and the system of demand, that is, the community of users of the built product. Manmade territory is the site of the clash between competing stakeholders and is the location of some of the most critical social, economic and environmental areas. To put an end to the progressive impoverishment of the productive fabric, of the users and managers of housing, it is necessary to rethink the operating standards of the entire chain, otherwise we risk the collapse of the system of building production and the support structures for housing difficulty.

Abstract: Foreign direct investments are very important for the implementation of strategic reforms, transfer of advanced technologies and managerial methods, thereby stimulating economic growth in developing countries and in particular, transition economies such as Albania is. During the last years, Albania experienced an increase in foreign investors’ interest in a wide range of sectors, with energy generation, telecommunication, cement production, mining, oil and industrial parks heading the list. However, the major obstacle factors for FDI inflows seem to remain the same: pervasive corruption, weak law enforcement, poor rule of law, lack of developed infrastructure, lack of a reliable energy supply and insufficiently defined property rights. Determining the factors that attract FDI, and furthermore identify the main characteristics of the host country’s economy, are essential to understand the reason of FDI inflows to a country or region. In the empirical perspective, various studies give different results. More specifically, this paper has focused on determining the factors for and against FDI in Albania.
