Antifungal Activity of Crude Extracts of Tectona grandis L.f. against Wood DecayFungi

引用

Phyton-International Journal of Experimental Botany 2022年第8期91卷 1795-1808页

作者： enrique Cárcamo-Ibarra mauro Manuel Martínez-Pacheco Abril Munro-Rojas Jorge enrique Ambriz-Parra Crisanto Velázquez-Becerra Facultad de Ingeniería en Tecnología de la Madera Universidad Michoacana de San Nicolás de HidalgoMorelia58030México Instituto de Investigaciones Químico-Biológicas Universidad Michoacana de San Nicolás de HidalgoMorelia58030México

Wood is mainly made up of cellulose, hemicelluloses, lignin polymers and other organic and inorganic substances, making it susceptible to deteriorate by various biological agents. Tectona grandis L.f. (Teak) is a timberspecies with high resistance to biological deterioration, valued for its durability, beauty, and mechanical *** purpose of this work was to evaluate the antifungal activity of crude extracts from teak on various fungi thatcause wood deterioration. For this, Teak heartwood was obtained, then fragmented and pulverized until obtaininga flour which was used for compounds extraction using the Soxhlet technique coupled to a rotary evaporatorthrough solvents of increasing polarity (hexane, dichloromethane, tetrahydrofuran, and acetone). The extractsobtained were tested against fungal organisms collected in the field, and the LC50 was determined using teak crudeextracts on Artemia salina as a biological model. The results obtained showed that a high flour yield was obtainedwith hexane (0.951 g), followed by tetrahydrofuran (0.446 g), dichloromethane (0.348 g), and acetone (0.152 g). Byusing nine fungal organisms that predominantly correspond to the genus Aspergillus, the extractable compoundswere tested, inhibiting 25% of mycelial growth with tetrahydrofuran (T. versicolor), and 40.9% with dichloromethane(G. trabeum). Likewise, the biological model of A. salina showed an LC50 of 84.9 μg/mL with hexane, 43.3 μg/mLwith dichloromethane, 59.6 μg/mL with tetrahydrofuran, and 54.7 μg/mL with acetone. For this reason, it is concluded that Teak wood contains many extractable compounds in relation to its weight, besides having antimicrobialactivity when extracted through polar compounds such as dichloromethane and tetrahydrofuran.

Caving performance through the integration of microseismic activity and numerical modeling at DOZ-PT Freeport,Indonesia

引用

International Journal of Minerals,Metallurgy and Materials 2009年第1期16卷 1-6页

作者： Rubio enrique Napitupulu Daulat Mining Engineering Department Universidad de Chile Geotechnical Engineering Department PT Freeport IndonesiaTembagapuraIndonesia

This article describes an undergoing research at PT Freeport, Indonesia, in which the main goal is to use the microseismic information recorded as a result of mining to analyze cave propagation and stress performance on the actual production and fixed infrastructure. At the moment, several numerical experiments have been conducted to correlate the mining activity with the microseismic events using the data collected during year 2005 and 2006. As a result of the preliminary analysis a micro- and a macrocracking envelop were proposed on the basis of computation of stress behavior at the location of the events. Stresses have been computed using standard elastic continuous boundary element models. The correlation between the average source radius and the stress performance has provided a method to propose a macrocracking criterion. Several techniques have been tested to nucleate the microseismic activity around different geological features. This last attempt was aimed to look at potential overstresses induced over the undercut and extraction level drifts. A method was devised to integrate the microseismicity into a 3-dimensional ride distribution model. This model has shown to be very effective to quantify the overstress induced as a result of computing volumetric microseismicity density. The volumetric microseismic model showed to induce overstress up to 10 MPa over a period of two months. The future work will concentrate on the calibration of the integrated model with actual damage observations made at the current mining infrastructure.

Internal Controllability for Parabolic Systems Involving Analytic Non-local Terms

引用

Chinese Annals of Mathematics,Series B 2018年第2期39卷 281-296页

作者： Pierre LISSY enrique ZUAZUA This article is dedicated to Phillippe G. Ciarlet in the occasion of his 80th birthday with gratitude and admiration/or his mastery and continuous support. Merci Philipp

This paper deals with the problem of internal controllability of a system of heat equations posed on a bounded domain with Dirichlet boundary conditions and perturbed with analytic non-local coupling terms. Each component of the system may be controlled in a different subdomain. Assuming that the unperturbed system is controUable--a property that has been recently characterized in terms of a Kalman-like rank condition--the authors give a necessary and sufficient condition for the controllability of the coupled system under the form of a unique continuation property for the corresponding elliptic eigenvalue system. The proof relies on a compactness-uniqueness argument, which is quite unusual in the context of parabolic systems, previously developed for scalar parabolic equations. The general result is illustrated by two simple examples.

On the material dependence of experimental shear fracture orientation

引用

Science China Earth Sciences 2015年第12期58卷 2357-2362页

作者： enrique GOMEZ-RIVAS Albert GRIERA Department of Geology and Petroleum Geology School of Geosciences King’s College University of Aberdeen Departament de Geologia Universitat Autònoma de Barcelona

It is not uncommon to observe shear fractures in ductile rocks oriented at more than 45° with respect to the maximum compression direction. Since these orientations cannot be explained with the classic Mohr-Coulumb or Tresca yield criteria, Zheng et al.(Journal of Structural Geology, 35: 1394–1405, 2011) proposed the maximum effective moment(MEM) failure criterion. This rule suggests that shear fractures in ductile rocks form at ?55° with the maximum compression axis and that this orientation is material-independent and, therefore, universal. Zheng et al.(Science China: Earth Sciences, 57(11): 2819–2824, 2014) used data from our own experiments as supporting evidence of their failure criterion. In this contribution we discuss why shear fracture formation in ductile rocks indeed strongly depends on the mechanical properties of the deforming medium, and why experimental data should not be taken to prove the validity of the MEM criterion. The formation mechanisms and orientations of shear fractures in our experiments significantly vary depending on the material strength and degree and type of anisotropy(composite and intrinsic). We therefore demonstrate using experimental data that a universal failure angle in ductile and anisotropic rocks does not apply. Additionally, we highlight some inconsistencies of the MEM criterion.

A UNIFIED FRAMEWORK FOR SITE SELECTION AND BUSINESS FORECASTING USING ANP

引用

Journal of Systems Science and Systems Engineering 2006年第2期15卷 178-188页

作者： enrique MU Katz Graduate School of Business University of PittsburghUSA

This paper reports an on-going application of the Analytic Network Process （ANP） in the context of a non-profit organization： The Latin American Studies Association （LASA）. This institution organizes a large international conference every eighteen months and needs to estimate conference attendance in advance （for logistic purposes） as well as selecting a host city where the combination of hotel infrastructure, conference costs, and so on, makes it a sound financial choice. In this paper, ANP will be used to： first, create a model to predict the relative number of attendees to the forthcoming 2009 LASA conference; and second, to create a Benefit-Cost-Risk （BCR） model to select the most suitable Latin American city as the conference site, This paper shows how the combination of these two ANP models, one for prediction and one for selection, can be used together for effective decision-making.
