Imágenes, Tablas, GráficasEl experimento se llevó a cabo en el municipio de Nuevo Colón (Boyacá) sector centro rural, con una duración de 45 días, se emplearon tres tratamientos con el fin de evaluar el bloque multinutricional elaborado a base de hoja de manzana (malus domestica), como alimento para conejos, frente a los parámetros productivos de los animales. El estudio se estableció con el propósito de generar nuevas alternativas alimenticias para conejos en etapa de levante y ceba, con la finalidad de reducir los costos de producción ya que al emplear el alimento balanceado comercial estos son muy altos, para llevar a cabo este estudio se emplearon 15 conejos destetos con treinta días de edad aproximadamente, de la raza nueva Zelanda, distribuidos al azar en tres grupos iguales de 5 animales cada uno, para ser sometidos a un tratamiento diferente, para el primero se empleó el 100 % de la ración a base de alimento balanceado comercial (ABC) 80 gramos día, el segundo 40 gramos de (ABC) Y Bloque multinutricional (BMN) ad libitum y para el tercero 100 % de (BMN) ad libitum. Para evaluar la diferencia entre los tratamientos se utilizó un análisis de Varianza con un arreglo completamente al azar. Las variables que se evaluaron Para los tres tratamientos fueron: ganancia de peso, consumo de alimento y conversión alimenticia. En ganancia de peso se obtuvieron los mejores resultados en el tratamiento 1 seguido del tratamiento 2 y por último el tratamiento 3, el mayor consumo de alimento se presentó en el tratamiento 1 seguido del tratamiento 2 el cual fue también superior al tratamiento 3, en cuanto a conversión alimenticia el mejor resultado se estuvo en el tratamiento 3, seguido el tratamiento 2 y por último el tratamiento 1, y para rendimiento en canal el mejor resultado se evidencio en el tratamiento 2 seguido del tratamiento 1 y por último el tratamiento 3. Teniendo en cuenta los anteriores resultados se puede evidenciar que los bloques multinutricionales se convierten en una buena opción alimenticia en conejos, como alimento complementario o como dieta total.The experiment was conducted in the town of Nuevo Colón (Boyacá) rural center industry, with a duration of 45 days, three treatments were used in order to evaluate the block Multinutrient sheet made from apple (Malus domestica) against the production parameters of the rabbit. The study was established with the purpose of generating new food alternatives to raise rabbits and fattening stage, in order to reduce production costs and that using the commercial feed these are very high, to carry out this study they used 15 weaned rabbits thirty days old about new Zealand race distributed blossom into three equal groups of 5 animals each, to be subjected to a different treatment to the first 100% of the ration was used to based commercial feed (ABC) 80 grams a day, the second 40 grams of ABC Block and multinutrient (BMN) ad libitum and for the third BMN 100% ad libitum.

Kinetic and equilibrium adsorption parameters estimation based on a heterogeneous intraparticle diffusion model

In this work, a commercial resin with a well-developed internal pore structure was chosen to adsorb four parabens used as probe molecules. The main novelty was to propose and validate a phenomenological transient adsorption model based on conservation law in both phases coupled with Langmuir’s equilibrium law and Fick’s mass transfer rate law inside the pores. With such an aim, a heterogeneous three-parameter intraparticle diffusion model, IPDM, was formulated, and its numerical solution was fitted to time-dependent concentration data by minimizing the sum of squared residuals. Equilibrium constants were also predicted by fitting Langmuir isotherm to equilibrium data. A monolayer capacity of 0.81 mmol/g was calculated for the four parabens regardless of the number of carbons in the ester group. With the optimal parameters values from the IPDM fitting process, a system of ODEs comprising local sensitivity coefficients as dependent variables was solved to compute the parameters’ variance-covariance matrix and infer their ranges for a 95% marginal confidence interval. In order to test the validity of the proposed model, an attempt to crosscheck between the parameters obtained by the estimation of the equilibrium related parameter, κ, and the modified capacity parameter, and the ones obtained by fitting the Langmuir’s isotherm to equilibrium data was carried out. As far as equilibrium related parameters concern, there is a relative agreement inside the limits of the confidence range between the estimated values of the amount adsorbed in equilibrium with initial bulk solution concentration, q0, and Langmuir’s equilibrium constant, K, adjusted to kinetic and equilibrium data, independently. Additionally, the order of magnitude of pore diffusivity obtained in this work is in accordance with the one predicted by Wilke-Chang correlation and is inversely proportional to the van der Waals volume raised to the power 0.53 in close agreement with the literature.The authors gratefully acknowledge financial support of this research work through the Comisión Interministerial de Ciencia y Tecnología (CICYT)-CTM2013-41354-R and Fundação para a Ciência e a Tecnologia (FCT)-UIDB/04730/2020 projects.info:eu-repo/semantics/publishedVersio

Colorimetric detection of hazardous gases using a remotely operated capturing and processing system

[EN] This paper presents an electronic system for the automatic detection of hazardous gases. The proposed system implements colorimetric sensing algorithms, thus providing a low-cost solution to the problem of gas sensing. It is remotely operated and it performs the tasks of image capturing and processing, hence obtaining colour measurements in RGB (Red Green Blue) space that are subsequently sent to a remote operator via the internet. A prototype of the system has been built to test its performance. Specifically, experiments have been carried out aimed at the detection of CO, CO2, NO, NO2, SO2 and formaldehyde at diverse concentrations by using a chromogenic array composed by 13 active and 2 inert compounds. Statistical analyses of the results reveal a good performance of the electronic system and the feasibility of remote hazardous gas detection using colorimetric sensor arrays.This research has been carried out in the framework of Project grant nos.

Selección masal por peso y coloración en tilapia roja

Para evaluar la efectividad de la selección masal por color y peso se analizaron dos generaciones (G1 y G2) de alevinos de tilapia roja Oreochromis sp. De 40.000 larvas a la sexta semana se eliminaron los alevinos manchados y blancos y a las 14 semanas se separaron por sexos. Se midió el peso (g), la longitud total (cm), la altura (cm) y el ancho (cm) de 150 individuos a las 6, 14 y 24 semanas de edad. En la semana 24 se escogieron 150 machos y 450 hembras con las coloraciones deseables y mayor peso. La selección resultó efectiva para coloración en G2, puesto que la proporción de individuos rojos se incrementó en 15% con respecto a los testigos. Entre generaciones (G1 y G2) el efecto de la selección fue positivo, debido a que la proporción de rojos se incrementó de 64% a 84% y se redujo la de manchados de 31% a 13%. En ambas generaciones los machos fueron significativamente más pesados que las hembras. Se encontraron notables diferencias entre generaciones para peso y talla, puesto que los selectos superaron al control en 27% y 8% (G1) y en 22% y 11% (G2) para el peso y la talla, respectivamente

A deletion at Adamts9-magi1 Locus is associated with psoriatic arthritis risk

Objective: Copy number variants (CNVs) have been associated with the risk to develop multiple autoimmune diseases. Our objective was to identify CNVs associated with the risk to develop psoriatic arthritis (PsA) using a genome-wide analysis approach. Methods: A total of 835 patients with PsA and 1498 healthy controls were genotyped for CNVs using the Illumina HumanHap610 BeadChip genotyping platform. Genomic CNVs were characterised using CNstream analysis software and analysed for association using the χ2 test. The most significant genomic CNV associations with PsA risk were independently tested in a validation sample of 1133 patients with PsA and 1831 healthy controls. In order to test for the specificity of the variants with PsA aetiology, we also analysed the association to a cohort of 822 patients with purely cutaneous psoriasis (PsC). Results: A total of 165 common CNVs were identified in the genome-wide analysis. We found a highly significant association of an intergenic deletion between ADAMTS9 and MAGI1 genes on chromosome 3p14.1 (p=0.00014). Using the independent patient and control cohort, we validated the association between ADAMTS9-MAGI1 deletion and PsA risk (p=0.032). Using next-generation sequencing, we characterised the 26 kb associated deletion. Finally, analysing the PsC cohort we found a lower frequency of the deletion compared with the PsA cohort (p=0.0088) and a similar frequency to that of healthy controls (p>0.3). Conclusions: The present genome-wide scan for CNVs associated with PsA risk has identified a new deletion associated with disease risk and which is also differential from PsC risk
