The global consumption of fossil fuels such as diesel and gasoline represent a considerable per-centage emissions, it is important to know for sure the percentage type gas emitted, there are many alternative energies that mitigate production emissions in different sectors transport sector energy sector. use hydrogen mixed with internal combustion engines viable because helps com-bustion process, but necessary behavior engine determine carbon footprint, quantify benefit these actions design...
Global fossil fuel consumption, including diesel and gasoline, significantly contributes to emissions. Understanding emission percentages types is critical. Alternative energies, like hydrogen mixed with help mitigate emissions in sectors such as transport energy. Hydrogen-gasoline blends internal combustion engines improve the process but require studying engine behavior carbon footprint. This research designs a low-cost sensor network monitor provide reliable data for statistical...
Nowadays, biodiesel is being promoted worldwide as a sustainable and alternative to diesel fuel. However, there still lack of market in Mexico. Hence, new initiative reform the Mexican biofuels framework by decree includes production use biodiesel. This regulation can ensure contribute development The proposes start from B5.8 blend end 2017 reach B10 2020. Therefore, objective present work was quality assessment blends proposed policy framework. techniques applied were Fourier transform...
Purpose This paper aims to identify the relationships among critical success factors (CSFs) for lean six sigma (LSS) implementation in higher education institutions (HEIs). Design/methodology/approach An extensive literature review was conducted design survey instrument, which authors later administered Mexican public HEIs existing CSFs and their impact on benefits obtained from implementing LSS projects. The data were empirically statistically validated using exploratory confirmatory factor...
Several studies have been conducted on alternatives to fossil fuels in internal combustion engines. In this work, we present an analysis of the optimization a spark ignition engine (SIE), which operates with mix gasoline and hydrogen. Thus, study tries enrich literature about effect using hydrogen SIEs taking into account their performance environmental issues. The experiments were considering three independent variables: revolutions, load produced by dynamometer, electrolyte concentration...
The gases emissions measurement systems in internal combustion engines are strict and expensive nowadays. For this reason, a virtual instrument was developed to measure the from an diesel engine, running with diesel-biodiesel mixtures. This software is called for (VIEM), it platform of LabVIEW 2010® programming. VIEM works sensors connected signal conditioning system, data acquisition system used as interface computer order monitor real time O 2 , NO, CO, SO CO gases. paper shows results...
It is not justifiable to use excess of water purify biodiesel only because it the "most economical" method. Actually one problems in production industry an adequate purification method; most commonly used washing. Currently, there considerable interest with other solid materials such as synthetic magnesium silicate, which effective absorbent remove impurities. The two methods discussed here have been tested similar conditions temperature, time and concentration reactants. was found that very...
The present investigation analyzes the performance of a Hatz diesel engine that has 912 cubic centimeters (cc), stationary type, two cylinders, an air cooled feature and B10 (90% 10% palm biodiesel), using test bench to improve statistically repeatability reproducibility runs. experimental reference tests were carried out under defined conditions at fixed speed 1800 revolutions per minute (rpm) four load levels: 35%, 50%, 65% 80%. analysis was based on technical standard NTC-ISO / IEC17025....
El biodiesel es un combustible producido mediante la transesterificacion de aceites vegetales o grasas animales, que en actualidad esta adquiriendo mayor atencion como sustituto del diesel. Representa una oportunidad para disminuir las emisiones CO2, SO2, CO, HC, HAP y MP, ademas contribuir a diversificacion combustibles matriz energetica Mexico. En el presente trabajo se muestran los resultados simulacion proceso combustion, tomando referencia especificaciones motor KUBOTA D600-B, opera con...
Dietary strategies can potentially help to reduce nitrogen (N) emissions and decrease the environmental impact of beef production. This study aimed evaluate effects dietary crude protein (CP) concentration on animal performance, N excretion, manure volatilisation finishing Holstein animals. In a first study, 105 bulls (BW 344 ± 2.6 kg; age 252 0.9 days) were allocated eight pens effect two treatments (medium (M) low (L), which contained CP 14.5% 12% DM basis, respectively) results confirmed...
The present work is about evaluating the emission characteristics of biodiesel-diesel blends in a reciprocating engine. biodiesel was produced and characterized before test. A virtual instrument developed to evaluate velocity, fuel consumption, temperature, emissions O2, CO, SO2, NO from an ignition-compression engine four cylinders with constant rate 850 rpm. percentages soybean-biodiesel (B) blended Mexican-diesel (D) analyzed were 2% B-98% D (B2), 5% B-95% B (B5), 20% B-80% (B20)....
This study investigates the fabrication and characterization of electrospun poly (ε-caprolactone)/poly (vinyl pyrrolidone) (PCL/PVP) fibers integrated with a nanocomposite chitosan, silver nanocrystals, graphene oxide (ChAgG), aimed at developing advanced wound dressing materials. The ChAgG nanocomposite, recognized for its antimicrobial biocompatible properties, was incorporated into PCL/PVP through electrospinning techniques. We assessed resultant fibers' morphological, physicochemical,...
Given the growing interest in manufacturing’s environmental effects, understanding impact of improvement strategies on sustainability is critical. This study focuses implementation Green Lean Six Sigma (GLSS) Mexican manufacturing sector, an area where research limited, particularly concerning barriers to successful outcomes. Through development a structural equation model using SPSS software,,version 25, 64-bit edition, key such as lack investment, insufficient participation, ineffective...
Cheese whey (CW) is a by-product of the cheese industry with pollution potential if not properly managed. This study evaluates biogas from CW samples Canary Islands. Empirical data were used to evaluate at factory, municipality, insular and regional level. 24 collected 17 different farms across Canaries, including industries (artisan/industrial), milk types (cow, goat, sheep, cow + goat sheep) post-treatments (cottage production, filtering skimming, inverse osmosis) their physical chemical...
Twenty-four individually housed Holstein bulls (456 ± 6.9 kg of body weight and 292 1.4 d age) were enrolled in a complete randomized experiment involving four dietary treatments to evaluate the potential effect mash particle size diets finishing beef on behavior, digestibility, macro- microscopic changes digestive tract. The all ingredients sieved at 2 mm (HM2), 3 (HM3), ingredients, but corn, corn 10 (HM210), (HM310). For HM210 HM310 mashes, ground was mixed with remaining concentrate or...
