Proporcionando un modelo integral para mejorar los indicadores de productividad de los empleados en la Organización Agrícola de Jihad de la provincia de Ilam

  The current study aims to design and explain a comprehensive model for employee productivity improvement indicators. This research is objectively a fundamental-practical study, naturally a survey research, and paradigmatically an exploratory blended research. The statistical population consists of human resource experts and organizational behavior in the qualitative section. The targeted sampling and snowball were used to identify the experts. Twenty experts were employed due to the data adequacy. To test the model, 245 employees of Agriculture Jihad Organization of Ilam province were used. The analysis method included the grounded theory and the structural equation approach. Data were collected through deep interviews along with a 69 item questionnaire. The grounded results indicate the fact that the supportive atmosphere and attention to the learning organization were identified in causal conditions. The main phenomenon of individual characteristics was identified in relation to the intervention conditions, the internal and external factors of the organization. The governing body of organizational culture and laws and regulations and merit-based leaders and human resources skills have been identified in relation to the main strategy of human resource management (HRM) practices. The main consequence of this model is also the productivity of human resources, and the results of the partial least squares model were approved and its relationships were correctly designed.El presente estudio tiene como objetivo diseñar y explicar un modelo integral de indicadores de mejora de la productividad de los empleados.

Biodiesel production by a novel composite of Fe (III)-based MOF and phosphomolybdic acid as an efficient and heterogeneous catalyst

The synthesis of MIL-53(Fe) samples and encapsulation process of phosphomolybdic acid implemented using ultrasound at ambient temperature and atmospheric pressure. Characterization of newly synthesized nanocomposite was carried out using various techniques such as XRD, FT-IR, SEM, EDS, BET and ICP. The catalytic activity of the prepared nanocomposites, PMA@MIL-53(Fe), was tested through the esterification reaction of oleic acid with ethanol under ultrasonic irradiation. Biodiesel production process using certain molar ratio of oleic acid/ethanol, PMA@MIL-53(Fe) as catalyst (10-200 mg) containing different amounts of PMA (0-40%), at different reaction times (5-20 minutes), total energy consumption (in watts, W) and ambient temperature under ultrasound conditions. The operating conditions of each of parameters were varied to study their effects on product yield. The results indicated that the synthesized composites show excellent catalytic activity. by encapsulating heteropoly acids in the MOF network, the challenges of using heteropoly acids, such as low contact surface and high solubility, are largely eliminated. The use of heteropoly acids in the industrial scales shows promise, provided the mentioned problems can be overcom

The Effects of the Toxicity of (Fe (so4).7H2o) on the isolated Mitochondria from the brain of rat

Introduction: Iron, through the reaction of Fenton, generates free radicals such as active oxygen radicals and activates the oxidative stress pathway. The oxidative stress due to the increased iron level in the brain regions plays  an important role in creation of neurodegenerative diseases. Methods and Results:In this study, the mitochondria of the brain tissue of Wild Wistar Rat isolated from various centrifuge rounds and with the concentrations of Fe (so4).7H2o were incubated at 30 and 60 minutes. To determine IC50 Fe (so4).7H2o, the mitochondrial survival ratio was measured by MTT test. Mitochondrial suspension with the concentration of 0.5 mg protein/ml at various concentrations of Fe (so4).7H2o was placed in a shaker incubator at 37° C for 30 and 60 minutes. Then the activity of mitochondrial complex 2 and the formation ratio of reactive oxygen species was investigated. The results showed that IC50 ratio for Fe (so4).7H2o was 20 and 5 μg/ml at 30 and 60 minutes, respectively, and mitochondria incubation isolated from the brain tissue of the rat with Fe (so4).7H2o can disrupt be the electron transfer chain and significantly increases the formation of reactive oxygen species compared to the control group (P <0.001). Conclusions:The findings of this study indicate that Fe (so4).7H2o disrupts electron transfer chain in the mitochondria and causes increasing ROS production. This excessive increase of ROS can activate the oxidative stress pathway and ultimately activate the cell toxicity pathways

Dynamic impedance studies of oxidation of nickel and glycerol at nickel electrodes.

This thesis uses dynamic electrochemical impedance spectroscopy (dEIS) to study how nickel undergoes electrooxidation. An electropolishing step is used to make a clean surface, and then the transformation of nickel to α-Ni(OH)2 is studied, including how a holding potential affects the double layer capacitance, surface structure and charge transfer resistance. Also, NiOOH is grown on the surface by sweeping to more positive potentials, and the activity of NiOOH toward glycerol electrooxidation is studied. It is shown that the free water content decreases on the surface (all or some portions of the surface, or possibly one or two monolayers close to the nickel surface) during the potential hold as determined by the decrease in measured capacitance. Oxidation of glycerol to glyceraldehyde is found to be the main reaction and the reaction mechanism is discussed.Graduate2019-10-2

Kinetics and Thermodynamics Studies of Copper (II), Mercury (II) and Chromium (III) Adsorption from Aqueous Solution by Peels of Banana

ABSTRACT The adsorption of Copper (II), Mercury (II) and Chromium (III) on peels of banana has been studied in batch mode using flame atomic absorption spectroscopy for metal estimation. The effects of Copper (II), Mercury (II) and Chromium (III) ions concentration, agitation time and temperature on adsorption of heavy metals onto peels of banana was investigated. The experimental isotherm results were fitted using Langmuir and Freundlich equations. The Langmuir and Freundlich model agrees very well with experimental data. The maximum amounts of Chromium (III), Copper (II), Mercury (II), adsorbed (q m ), as evaluated by Freundlich isotherm, were 9.01 mg, 8.81 mg and 7.65 per gram of powder of peels of banana, respectively. In the kinetic study, pseudo-first-order and pseudo-second-order were tested, and was found to follow closely the pseudo-second-order kinetic model. The negative values of Gibb's free energy change (ΔG°) showed that the adsorption process was feasible and spontaneous in nature
