Aproximaci?n a la estimaci?n espacial de sequ?as meteorol?gicas en la cuenca hidrogr?fica del rio Coello, Colombia
15 p. Recurso Electr?nicoLa evaluaci?on espacio temporal para la caracterizaci?on de las sequ??as meteorol?ogicas se bas?o en datos de precipitaci
?on mensual acumulada entre 1996-2005 de 20 estaciones meteorol?ogicas distribuidas en la cuenca hidrogr?afica del r??o
Coello. Se realiz?o un preprocesamiento a los datos de precipitaci?on con pruebas de consistencia de datos para corregir y eliminar
datos sobre o sub estimados. Para estimar los datos faltantes de precipitaci?on se comparan tres m?etodos geoestad??sticos de interpolaci
?on, derivados de Kriging, asociados con variables secundarias como el Kriging Ordinario, CoKrigin Ordinario asocidadas a
las variables secundarias de un Modelo de Elevaci?on Digital y datos de precipitaci?on satelital TRMM. Para seleccionar el m?etodo
geoestad??stico se compar?o el ajuste de cada interpolaci?on con respecto a tres estaciones de referencia a trav?es de tres pruebas
de calidad, las cuales fueron Ra??z del Error Cuadr?atico Medio (RMSE), Criterio de Informaci?on de Akaike (AIC) y Criterio de
Informaci?on Bayesiano (BIC). En esta investigaci?on dos de tres pruebas favorecen al CoKriging Ordinario usando como variable
secundaria la Altitud (CoK+DEM). Con la serie interpolada de precipitaci?on se evaluaron y caracterizaron las sequ??as por medio
del ?Indice de Precipitaci?on Estandarizado (SPI) a escala mensual y trimestral, calculando los par?ametros de severidad, duraci?on,
intensidad y frecuencia de las sequ??as. Por medio de mapas se delimitaron las regiones en donde se presentan los valores negativos
de SPI. En el an?alisis espacio temporal los meses de Enero, Febrero, Julio y Agosto son los m?as secos del a?no. En el a?no
1997 se present?o la sequ??a meteorol?ogica de mayores afectaciones en la cuenca del r??o Coello generalmente concentrados en la
parte media y baja de la cuenca, con una intensidad maxima de -2,57 de SPI.
Palabras Clave: Sequ??a meteorol?ogica; m?etodos de interpolaci?on geoestad??sticos; ?Indice de Precipitaci?on Estandarizado

precipitation between 1996-2005 from 20 meteorological stations distributed in the Coello River basin. Data precipitation was
performed preprocessing with data consistency tests to correct and delete data over- or under estimated. To estimate missing
precipitation data are compared three geostatistical interpolation methods derived from Kriging, associated with secondary variables
such as the Ordinary Kriging, CoKrigin Ordinary associated with secondary variables of a Digital Elevation Model and
data satellite TRMM. To select the statistical method the setting of each interpolation was compared with respect to three reference
stations through three quality tests, which were Root Mean Square Error (RMSE), Akaike Information Criterion (AIC) and
Bayesian Information Criterion (BIC). In this investigation two of three tests favor the Ordinary CoKriging using as a secondary
variable Altitude (COK+DEM). With the interpolated series of precipitation were evaluated and characterized by drought Standardized
Precipitation Index (SPI) at monthly and quarterly scale, calculating the parameters of severity, duration, intensity and
frequency of droughts. By mapping are delimited the regions where occur the more negative values of SPI. In analyzing spacetemporal
the months of January, February, July and August are the driest of the year. In 1997 the meteorological drought greatest
damage occurs in the Coello River basin generally concentrated in the middle and lower part of the basin, with a maximum
intensity of SPI -2,57.

Use of airborne vehicles as research platforms
This is the accepted version of the following chapter: Gratton, G. 2012. Use of Airborne Vehicles as Research Platforms. Encyclopedia of Aerospace Engineering, which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1002/9780470686652.eae604/full. Copyright @ John Wiley & Sons 2012.The use of aircraft is often valuable to position airborne sensors or to conduct experiments in ways not possible purely on the ground. An airframe, typically an older one, must be selected then adapted to the role – likely to include inlets, windows, structural changes, power supply, computing and data recording capacity, and likely the provision of external hardpoints. Once the research vehicle is created, the instruments on board will require calibration, either in isolation or by intercomparison against already calibrated instruments on board another aircraft. This calibration process will continue throughout the life of the airplane. Additionally, an operating organization must be created and obtain any necessary organizational approvals. For some specialist applications, unmanned aerial vehicles (UAVs) may also be used, which carry some special considerations of autonomy and interoperability, but similar concerns of instrument, vehicle, and operational integrity
Caracterizaci?n y manejo de residuos s?lidos, de siete predios en Salento, Quind?o
99 P?ginasEl trabajo de caracterizaci?n para la identificaci?n de los residuos s?lidos y su manejo en siete fincas lecheras de peque?os productores en el municipio de Salento, se realiz? haciendo el seguimiento durante un mes y consignando los datos obtenidos en tablas de chequeo, las cuales permitieron, hacer un an?lisis y procesar la informaci?n en cuadros y gr?ficos para obtener un panorama claro de la situaci?n real del manejo de residuos s?lidos en la zona rural.
Los estudios realizados dan como resultado que en los 7 predios de ASOGASA del municipio de Salento, se est?n produciendo aproximadamente 212 kg de residuos org?nicos mensuales y 237.7 kg con otros residuos (papel, material infeccioso biol?gico y vidrio) Y en los 21 predios de la asociaci?n se producir?a un estimado de 470 kg de materia org?nica mensual, papel con 32 kg y 6.4 kg para material biol?gico, infeccioso y de vidrio 17.7 kg, para un total de 526.1 kg de residuos totales, cifras que son bastante significativas, si se mira el monto de desechos al a?o.
Pero, el problema no radica en la cantidad de residuos producidos en la zona, sino en el mal manejo que se da a los mismos, en su gran mayor?a los habitantes de la zona rural desconoce las normas m?nimas para el control de ?stos y el da?o que se hace al medio ambiente, as? mismo, puede verse que no existen organizaciones del Estado que se ocupen del tema. Cabe anotar la importancia de poner en conocimiento a la administraci?n municipal de la problem?tica que se vive en sus campos, para que hagan presencia y procuren generar programas de capacitaci?n que ayuden a los campesinos para que hagan un mejor uso de los residuos s?lidos y de paso ayuden a conservar el ecosistema.ABSTRACT. The characterization work for the identification of solid waste and its management in seven smallholder dairy farms in the town of Salento, was following up for a month and obtained by attaching the check tables, which allowed, do analysis and process information in tables and graphs to get a clear picture of the real situation of solid waste management in rural areas.
Studies resulting in the seven grounds ASOGASA the municipality of Salento, are producing approximately 212 kg of organic waste per month and 237.7 kg with other waste (paper, glass and biological infectious material) and in the 21 plots of association produce an estimated 470 kg organic matter monthly paper with 32 kg and 6.4 kg for biological material, infectious glass and 17.7 kg, for a total of 526.1 kg of total residues, numbers that are significant enough, when viewed the amount of waste a year.
But, the problem is not the amount of waste produced in the area, but in the mismanagement that is given to them, the vast majority of people in rural areas know the minimum standards for the control of these and the damage is done to the environment, so it can be seen that there are no state organizations that address the issue. It is worth noting the importance to inform the municipal administration of the problems being experienced in their fields, to make presence and seek to create training programs that help farmers to make better use of solid waste and step help preserve the ecosystem.INTRODUCCI?N 15

Evaluaci?n de la calidad nutricional, consumo y digestibilidad in vivo de los henos de pasto vidal (Bothriochloa saccharoides), Colosuana (Bothriochloa pertusa) y Angleton Climacuna (Dichanthium annulatum)
52 P?ginasRecurso Electr?nicoLas producciones ganaderas de Am?rica Tropical se basan en el suministro de forrajes de baja calidad nutricional que son convertidos en alimentos de alta calidad proteica como carne y leche. El objetivo de este estudio fue determinar la calidad nutricional, el consumo y la digestibilidad aparente de tres gram?neas henificadas (B. saccharoides, B. pertusa, D. annulatum). El experimento se desarroll? en el Centro Universitario Regional del Norte del Tolima en el municipio de Armero Guayabal Tolima, a una altura de 275 m.s.n.m; temperatura de 26 ?C y precipitaci?n anual de 1732 mm. El dise?o experimental fue Cuadrado Latino 3*3. Para la determinaci?n de la digestibilidad aparente se utiliz? el m?todo in vivo colecta total de heces; se emplearon 12 ovinos machos mestizos que fueron alojados en jaulas metab?licas. De igual forma se emple? esta fase para realizar mediciones de consumo. Las muestras de gram?neas y heces recolectadas se evaluaron en el laboratorio de Ecofisiolog?a de la Universidad del Tolima y la Universidad de Nari?o. Los datos se analizaron a partir del software Infostat?, realizando ANOVA y Tukey (p= 0.05). El resultado del an?lisis bromatol?gico, fue similar para las tres gram?neas incluyendo los metabolitos secundarios; se observaron datos de digestibilidad superiores para B. saccharoides seguido por el B. Pertusa y por ?ltimo D. annulatum. Sin embargo los pastos B. pertusa y D. annulatum presentaron mejor consumo con respecto a B. saccharoides.ABSTRACT. Livestock production in tropical America are based on the supply of fibrous foods that are converted to high quality food protein as meat and milk, which is why studies seeking to confirm an improvement in digestibility and intake of grasses ensuring greater conversion nutritional management based on a more accurate. The present study aimed to determine the nutritional quality, consumption and apparent digestibility three grasses (B. saccharoides, B. pertusa, D. annulatum) the dry tropics of northern Tolima. The pilot phase was developed in the CURDN center in Armero-Tolima, (South America or Colombia) at 275 meters below the sea level temperature of 26 ? C and annual rainfall of 1732 mm. The experimental design was a Latin Square 3 * 3, with three treatments and three experimental periods was used. For determining the in vivo digestibility was used method through total feces collection; 12 crossbreed male sheep were housed 14 days to adaptation and 3 days to the experimental period in metabolic cages. Collection and weighing of food and feces declined in each of the experimental periods cages were used. Likewise this phase is used to perform power measurements, weighing the quantity of feed and 24 hours after rejections. Samples collected grasses and feces were evaluated in the laboratory of Ecophysiology of Tolima University and the University of Nari?o. Data were analyzed from Infostat? software, performing Anova and Tukey (p = 0.05). The nutritional analysis was similar for the three grasses including secondary metabolites; higher digestibility data B. saccharoides followed by B. pertusa and finally D. annulatum observed. However pertusa pastures B. and D. annulatum had better consumption relative to B. saccharoides.INTRODUCCI?N 10
