Authors: Adebayo Elijah A. , Azeez Musibau A. , Majolagbe Olusola N. , Oloke Julius K. 
Published: August 2018

Abstract
Genetic diversity in nineteen strains of Pleurotus was studied using morphometric traits and growth factors. Ability of the isolates of these strains to tolerate different ranges of temperature and pH were evaluated. Highest mycelial growth rates were obtained at 25 °C (mutants and hybrids) and 30 °C (wild type), while LAU 90 (mutant) performed satisfactorily at all evaluated temperature ranges (15-35 °C). Highest mycelial yields (dry weight) were produced by LAU 90 at different pH regimes (4.0 - 9.0), while hybrids LN 97 and LN 98 maximally produced mycelial yield at pH 5.0 and 7.0, respectively. Analysis od Principal component (PC) revealed that components of these strains accounted for 86.1% of total variations among the strains with first PC recording 44.6%. The dendrogram discriminated nineteen Pleurotus genotypes into two major genetic groups with mutants and hybrid strains in Cluster A, separated distinctly from wild parents in Cluster B, indicating genetic diversity. The expression of heterosis can be maximized by information obtained among the hybrid strains and mutant (LAU90) strain. The hybrid (LN98) strain with superior performance may be selected for adoption in commercial mushroom production.
Interaction Between Caseinate and Carrageenans Results in Different Physical and Mechanical Properties of Edible Films
Authors: Totosaus Alfonso , Gutierrez Reyna , Pérez-Chabela M. Lourdes 
Published: August 2018

Abstract
Edible films were elaborated with sodium caseinate and different types of carrageenans (iota, kappa or lambda), and glycerol as plasticizer, to determine the different specific interactions between caseinate and carrageenans on physical and mechanical properties via a response surface methodology approach. The different sulphate groups content in the different carrageenans affected differentially edible films properties. The use of lambda carrageenan in edible film formulation resulted in more soluble and permeably film, with a concomitantly both less rigid and more elastic structure. The edible film formulation was optimized to 8.0 % of caseinate, 0.4% of carrageenan (irrespectively of the type) and 0.3% of glycerol.
Experimental Assessment of the Meliss Simulation Model Accuracy of the Direct Solar Irradiance in Brasov, Romania

Published: August 2018

Abstract
The solar irradiance is the main input parameter when designing solar energy conversion systems. A poor accuracy of the solar irradiance simulation models negatively affect the output energy and the durability of the solar energy conversion system. In the paper, the measured values of the direct solar irradiance in the entire month of July 2016 are analysed and, based on the daily received direct solar energy and the variability of the direct solar irradiance, the days are classified in four categories: clear sky days, partially clear sky days, partially cloudy days and cloudy days. Based on this classification, only four clear sky days were identified in July 2016. The same procedure was applied for the months of July 2013, 2014 and 2015 resulting 13 clear sky days in the entire monitoring period of four years (2013-2016). The measured values of the direct solar irradiance in these 13 selected clear sky days are comparatively analysed against the direct solar irradiance simulated with Meliss clear sky model. Further on, a statistical analysis is performed for the time interval 8:00-16:00 to evaluate absolute, relative and root mean square errors between the measured and simulated values. The results show that the simulation model overestimates, in eleven out of the thirteen clear sky days, the solar direct irradiance in the central part of the day. The measurements were performed in the Renewable Energy Systems and Recycling (RESREC) Research Centre located in the R&D Institute of the Transilvania University of Brasov, Romania.
Effect of Cu2O Morphology on Photovoltaic Performance of P-Type Dye-Sensitized Solar Cells
Authors: Ursu Daniel , Dabici Anamaria , Vajda Melinda , Bublea Neli-Camelia , Duteanu Narcis , Miclau Marinela 
Published: August 2018

Abstract
Cuprous oxide with different morphologies (3D hierarchical structure consisting of the micrometer dendritic rods and the porous truncated octahedrons) has been successfully synthesized via a facile one-step hydrothermal method using copper (II) acetate and ethyl cellulose as reactants. The p-type dye-sensitized solar cell based on the micrometer porous structure exhibits approximately 15% increase in JSC and VOC than 3D hierarchical structure. This enhancement could be explained by the high dye loading capacity of this porous structure and lowering the recombination process at the oxide/dye/electrolyte interface.
H2 and Syngas Production From Catalytic Cracking of Pig Manure and Compost Pyrolysis Vapor Over Ni-Based Catalysts

Published: August 2018

Abstract
Catalytic cracking of volatiles derived from wet pig manure (WPM), dried pig manure and their compost was investigated over Ni/Al2O3 and Ni-loaded on lignite char (Ni/C). Non-catalytic pyrolysis of WPM resulted in a carbon conversion of 43.3% and 18.5% in heavy tar and light tar, respectively. No tar was formed when Ni/Al2O3 was introduced for WPM gasifi cation and the gas yield signifi cantly reached to a high value of 64.4 mmol/g at 650oC. When Ni/C was employed, 5.9% of carbon in the light tar was found at 650oC, revealing that the Ni/C is not active enough for cracking of tarry materials. The pyrolysis vapor was cracked completely and gave a H2-rich tar free syngas in high yield. High water amount of WPM promotes steam gasifi cation of char support, causing the deactivation of Ni/C. Such a study may be benefi cial to the development of livestock manure catalytic gasifi cation technology.

Vemos cómo las caminatas aleatorias generan algunas ecuaciones diferenciales parciales tales como la ecuación de calor; se presenta la ecuación de Laplace resuelta usando el juego Tour du wino; es decir, simulación Montecarlo para obtener los valores de una función armónica, como los promedios de su valores en la frontera obtenidos por diferentes trayectorias. Se revisan los modelos de Black and Scholes, así como el método de funciones generadoras de probabilidad para mostrar como determinados problemas probabilísticos pueden resolverse usando métodos determinísticos basados en ecuaciones diferenciales ordinarias y parciales.Palabras clave: modelos determinísticos, modelos probabilísticos, Montecarlo, caminatas aleatorias, Black and ScholesAbstract This work presents a review of some deterministic and stochastic models, interesting rela­tionships between them, are also discussed. Random walks give rise to partial differential mo­dels such as the heat equation. A Tour du wino game is introduced to approximate a solution to Laplace equation, here a Monte Carlo simulation is used to obtain the values of an harmonic function as the average of its boundary values using random trajectories. We review the Black & Scholes and the probability generating functions models to show how some probabilistic pro­blems can be solved using deterministics methods (based on ordinary and partial differential equations).Keywords: BDeterministic models; Stochastic models; Monte Carlo; random walk; Black and Scholes
