Como consecuencia del uso intensivo de pesticidas pertenecientes al mismo grupo químico en artrópodos como los ácaros se induce la generación de resistencia, la cual se ve desarrollada a nivel genético con la afectación de no solo uno si no de varios genes (resistencia poligénica), lo cual conlleva a la modificación de diferentes rutas metabólicas y trae consigo la resistencia indirecta sobre el efecto de otros insecticidas, generando así un circulo que puede manifestarse en la dificultad para controlar algún tipo de plaga como es el caso de Phyllocoptruta oleivora (Ashmead) (ácaro tostador) y Polyphagotarsonemus latus (ácaro blanco) en Limón Tahití (Citrus latifolia Tanaka) en la zona de EL ESPINAL, TOLIMA con el uso repetido de abamectinas, por tal razón se evalúo diferentes moléculas empleadas comercialmente en el control de ácaros en cultivos diferentes como VULCANO 420 EC , MILBEKNOCK EC 9,3 , KENDO SC, DANISARABA SC , VEKTOR Y MYCOTROL SE buscando establecer un Manejo Integrado de Plagas basado en rotación de compuestos, también se evaluó manejos que empíricamente han presentado resultados favorables en campo sin emplear productos comerciales que estén enfocados al control de plagas y que son de fácil acceso como detergentes encontrándose resultados cualitativos iniciales más efectivos que los presentados por los acaricidas ensayados.Abstract. Like a consequence of an intensive use of pesticides belonging at the same chemical group over arthropods like mites induces generation of resistance, which have been developed at genetically level over several gens (polygenetic resistance), that is carrying on the modification of different path ways with the consequence to the indirectly resistance over the action of the other insecticides, generating a circle that can manifest in the difficult to control some kind of plague like is case of Phyllocoptruta oleivora (Ashmead) (roast mite) and Polyphagotarsonemus latus (white mite) in acid lime (Citrus latifolia Tanaka) on the EL ESPINAL ZONE, TOLIMA with the repeated use of abamectins, for that reason was evaluated different commercial molecules to control mites in another crops like VULCANO 420 EC , MILBEKNOCK EC 9,3 , KENDO SC , DANISARABA SC , VEKTOR Y MYCOTROL SE , looking for establishment a Plague Integrated Management based on compound rotation, also was evaluated management that empirically has given good effect in field without use a commercial products focused to plague control and to easy access like detergent, finding beginning qualitative results more effective than present by acaricides used.Pregrad

Tratamento de lixiviado de aterro sanitário com carvão ativado obtido de resíduos de café

A set of experiments were carried out in order to establish and evaluate the potential of activated carbon, produced from coffee waste in adsorption process, in the depuration of landfill leachate. Different reagents were studied in the activation of carbon: HCl, HCl + H2O2, H3PO4, H3PO4 + H2O2, all with an impregnation rate of 1:1. The activated carbon that showed the best global results was activated with H3PO4, obtaining a 51.0, 32.8, 66.0, 81.0 and 97.1% elimination of chemical oxygen demand, ammonia, total chlorine, bromine and copper, respectively. This activated carbon has a total pore area of 4.85 m2/g and a median pore diameter of 65.32 micrometers. When different loads of this carbon were placed in a stirrer system in contact with landfill leachate, with the aim of evaluating the effect of the adsorption load and contact time, the concentration of ammonia decreased from the beginning of the adsorption process to the end of it, and the removal of ammonia increased with the increase in the adsorbent load. However, the trend of the amount adsorbed per unit mass decreased with increased dosage. The model Freundlich equilibrium isotherm fits experimental data adequately, giving R2 values of 0.95, 1/n of 0.5183, and a K value of 7.08*10-5 L/g, being favourable for adsorption process.Foi realizada uma série de experimentos para estabelecer e avaliar o potencial de carvão ativado produzido de resíduos de café por meio de um processo de adsorção na depuração do lixiviado de aterro sanitário. Foram estudados diferentes reagentes para a ativação do carvão: HCl, HCl + H2O2, H3PO4, H3PO4 + H2O2, todos com taxa de impregnação de 1:1. O carvão que apresentou os melhores resultados foi ativado com H3PO4, obtendo uma eliminação de 51,0; 32,8; 66,0; 81,0; e 97,1% de demanda química de oxigênio e concentração de amônia, cloro total, bromo e cobre, respetivamente. O referido carvão ativado tem uma área total de poro de 4,85 m2/g e diâmetro médio de poro de 65,32 micrômetros. Com o objetivo de avaliar o efeito da carga de adsorção e do tempo de contato, foram colocadas diferentes cargas desse carvão em um sistema de agitação em contato com o lixiviado de aterro sanitário. Observou-se que a concentração de amônia diminuiu e que sua remoção foi maior à medida que a carga adsorvente aumentava. No entanto, a quantidade adsorvida por unidade de massa diminuiu com o aumento da dosagem. Os dados experimentais adequaram-se corretamente ao modelo de isoterma de Freundlich, obtendo-se valores de R2 de 0,95, 1/n de 0,5183, e um valor de K de 7,08*10-5 L/g, considerados favoráveis para o processo de adsorção.Ministerio de Educación (Chile) 1114021

Amino Acid Plasma Concentrations and Urinary Excretion in Young Diabetics

The aim of this study is to analyze amino acid plasma profile in a group of young diabetics and to evaluate its application as markers of metabolic control of the disease, as well as to analyze the urinary excretion of amino acids in these patients. A clinical assessment and metabolic study (amino acid serum concentrations and urinary excretion of amino acids) was accomplished in a group of 49 children diagnosed with diabetes, and a group of 48 healthy children (control group). The plasma levels of total amino acids as well as branchedchain, glucogenic and ketogenic amino acids were significantly higher (p < 0.05) in the diabetic group with respect to the control group. Total as well as branched-chain, glucogenic and ketogenic amino acids urinary levels were significantly lower (p < 0.05) in the diabetic group compared to the control group. The study of the amino acid plasma in the young diabetic reflect disturbances in protein/amino acid metabolism and, consequently, in metabolic control of the disease. The study of amino acid urinary excretion might have interest not only in the context of diabetic nephropathy, but also in the revealing of partial aspects of amino acid metabolism and, probably, in the metabolic control of the disease

Information flow between resting state networks

The resting brain dynamics self-organizes into a finite number of correlated patterns known as resting state networks (RSNs). It is well known that techniques like independent component analysis can separate the brain activity at rest to provide such RSNs, but the specific pattern of interaction between RSNs is not yet fully understood. To this aim, we propose here a novel method to compute the information flow (IF) between different RSNs from resting state magnetic resonance imaging. After haemodynamic response function blind deconvolution of all voxel signals, and under the hypothesis that RSNs define regions of interest, our method first uses principal component analysis to reduce dimensionality in each RSN to next compute IF (estimated here in terms of Transfer Entropy) between the different RSNs by systematically increasing k (the number of principal components used in the calculation). When k = 1, this method is equivalent to computing IF using the average of all voxel activities in each RSN. For k greater than one our method calculates the k-multivariate IF between the different RSNs. We find that the average IF among RSNs is dimension-dependent, increasing from k =1 (i.e., the average voxels activity) up to a maximum occurring at k =5 to finally decay to zero for k greater than 10. This suggests that a small number of components (close to 5) is sufficient to describe the IF pattern between RSNs. Our method - addressing differences in IF between RSNs for any generic data - can be used for group comparison in health or disease. To illustrate this, we have calculated the interRSNs IF in a dataset of Alzheimer's Disease (AD) to find that the most significant differences between AD and controls occurred for k =2, in addition to AD showing increased IF w.r.t. controls.Comment: 47 pages, 5 figures, 4 tables, 3 supplementary figures.

Effect of two oil types and energy levels on broiler performance, carcass quality and skin pigmentation

This study evaluated different levels of metabolisable energy (ME) and two oil types: crude soybean oil (CSO) and acidulated soybean oil (ASO), in sorghum-soybean meal diets for broilers. One thousand and eight unsexed Ross 308 chicks aged 1 to 49 days old were used in a factorial arrangement design 2x3. The first factor corresponded to the oils (CSO and ASO) and the second factor corresponded to the ME levels (high, medium and low) in the initiation (1-10 days), growing (11-25 days) and finishing (26-48 days) feeds, with a 90 kcal/kg reduction. The treatments were as follows: (1) CSO with 3010, 3175 and 3200 kcal/kg; (2) CSO with 2920, 3085 and 3110 kcal/kg; (3) CSO with 2920, 3085 and 3200 kcal/kg; (4) ASO with 3010, 3175 and 3200 kcal/kg; (5) ASO with 2920, 3085 and 3110 kcal/kg; and (6) ASO with 2920, 3085 and 3200 kcal/kg. The treatments with high and medium levels of ME (P&lt;0.05) were higher. The carcass weight and skin pigmentation when cold were better in broilers fed with high and medium levels of ME (P&lt;0.05). No effect (P&gt;0.05) between oil types was found. It can be concluded that it is feasible to replace CSO by ASO and to reduce 90 kcal/kg of ME from the recommended amount for the breed during the initiation and growing stages, without affecting their performance
