Eco-innovation practices’ adoption in the automotive industry

Eco-innovation is a construct that is gaining increasing interest from academics and researchers since it is commonly considered in the literature as one of the strategies that allow manufacturing companies not only to significantly reduce the negative impacts on the environment but also the generation of pollutants. However, little is known about the adoption of eco-innovation practices in manufacturing companies, particularly in the automotive industry. Therefore, this research has as main objective to fill this gap in the literature and explore the interdependence between eco-innovation of products, processes and management. The study is conducted through a research framework consisting of 3 measurement scales, 14 items and 3 hypotheses and an extensive review of the literature. A self-administered questionnaire was distributed to a sample of 460 companies in the automotive and auto parts industry in Mexico. Data were analyzed through Confirmatory Factor Analysis, Descriptive Statistics and Structural Equation Modelling. The results obtained show that product eco-innovation, process eco-innovation and management eco-innovation are good indicators for the adoption of eco-innovation practices for companies in the automotive and auto parts industry. The paper addresses a research gap in the academic literature in the eco-innovation field by providing evidence on the interdependence between eco-innovation of products, processes and management and the implementation of their practices in the automotive industry.N/

Beyond Lean Manufacturing and Sustainable Performance: Are the Circular Economy practices worth pursuing?

Purpose - The need to improve sustainability in manufacturing firms, which would allow them to reduce the emission of pollutants and the generation of industrial waste, has stimulated the adoption of Circular Economy (CE) alongside lean manufacturing practices to significantly improve the sustainable performance of organizations. However, empirical evidence provided in previous studies and that has related the practices of lean manufacturing, CE, and sustainable performance does not allow establishing an interconnection between these three concepts. Therefore, this paper fills this gap in the literature by exploring the relationship between these three concepts. Design/methodology/approach - A quantitative study in which data was collected from 460 managers working in the automotive industry in Mexico was conducted. The data allowed the testing and validation of four hypotheses through the use of partial least squares structural equation modelling. Findings - The results obtained suggest that lean manufacturing practices have a significant positive influence both on sustainable performance and CE. In turn, the results also demonstrate the existence of a significant positive relationship between Circular Economy and the sustainable performance of manufacturing firms in the automotive industry as well as that CE has a positive role in mediating the interconnection between lean manufacturing practices and sustainable performance. Originality – This is one of the first studies that have investigated the relationship between lean manufacturing, CE, and sustainable performance, particularly, in the automotive sector. Practical implications – The results obtained from the present study will allow entrepreneurs in the automotive industry and industry professionals as well as government authorities to formulate more effective policies and strategies to support the improvement of environmental sustainability performance in the manufacturing sector

The bias-extension test for the analysis of in-plane shear properties of textile composite reinforcements and prepregs: a review

The bias-extension test is a rather simple experiment aiming to determine in-plane shear properties of textile composite reinforcements. However the mechanics during the test involves fibrous material at large shear strains and large rotations of the fibres. Several aspects are still being studied and are not yet modeled in a consensual manner. The standard analysis of the test is based on two assumptions: inextensibility of the fibers and rotations at the yarn crossovers without slippage. They lead to the development of zones with constant fibre orientations proper to the bias-extension test. Beyond the analysis of the test within these basic assumptions, the paper presents studies that have been carried out on the lack of verification of these hypothesis (slippage, tension in the yarns, effects of fibre bending). The effects of temperature, mesoscopic modeling and tension locking are also considered in the case of the bias-extension test

Estudio cinético e isotérmico de la biosorción de Zinc (II) y Cadmio (II) para un sistema monometálico-bimetálico por Undaria pinnatífida sp

Se estudió la capacidad de adsorción que tiene el alga marina Undaria pinnatifida sp. en la adsorción de los iones metálicos de zinc y cadmio para un sistema individual (monometalico) y en mezclas (bimetálico) de una solución acuosa. Se estudió preliminarmente para este proceso, el tiempo de contacto, pH de la solución y tratamiento del biopolímero. El estudio de la cinética determinó que el comportamiento del sistema de adsorción fue de pseudo segundo orden usando la ecuación de Langergren (concentración inicial 50 mg/L, peso del biopolímero = 0,4g; pH = 3 - 5). El modelamiento no lineal de las isotermas de Langmuir y Freundlich, con el modelo de Langmuir se obtuvo un mejor coeficiente de correlación cercano a la unidad, determinándose que la máxima capacidad de sorción de los iones metales como zinc fue qmax = 44,91 mg/g y cadmio qmax = 102,38 mg/g a pH = 4 en un tiempo de contacto de 60 minutos, con el alga sin tratamiento en el sistema monometálico, siendo más eficiente la adsorción para el ion cadmio. Para el sistema bimetálico se empleó dos métodos: el método de las isoconcentraciones que dio a conocer el comportamiento en la adsorción de ambos metales en solución y el método de las concentraciones variables empleando el análisis de regresión del modelo de Langmuir modificado, que dio a conocer los valores de la capacidad máxima de adsorción, siendo para el ion metálico zinc qmax = 0,27 mmol/g; cadmio qmax= 1,27 mmol/g y para la adsorción de ambos metales sobre la biomasa qmax= 1,13 mmol/gFil: Mori C., M..

We studied this process preliminarily, contact time, pH of the biopolymer solution and treatment. The kinetic study of the behavior determined that the adsorption system was pseudo second-order equation using the Langergren (initial concentration 50mg/L, weight = 0,4g biopolymer, pH = 3 - 5). The nonlinear modeling the Langmuir and Freundlich isotherm, the Langmuir model obtained a better correlation coefficient close to unity, determining the maximum sorption capacity of metals such as zinc ions was qmax = 44,91mg/g and cadmium qmax = 102,38 mg/g at pH = 4 at a contact time of 60 minutes, with the alga in untreated monometallic system, being more efficient for the ion adsorption cadmium. For bimetallic systems used two methods, the method disclosed isoconcentrations that the adsorption behavior of both metals in solution and method of varying concentrations employing the regression analysis model modified Langmuir unveiled values of the maximum adsorption capacity, while for the zinc metal ion qmax = 0,27 mmol/g, cadmium qmax = 1,27 mmol/g for the adsorption of both metals on biomass qmax = 1,13 mmol/gCentro de Investigación y Desarrollo en Fermentaciones Industriale

Measurement of the production of high-p(T) electrons from heavy-flavour hadron decays in Pb-Pb collisions at root s(NN)=2.76 TeV

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPElectrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass of energy root s(NN) = 2.76 TeV. The transverse momentum (pT) differential production yields at mid-rapidity were used to calculate the nuclear modification factor R-AA in the interval 3 < p(T) < 18 GeV/c. The R-AA shows a strong suppression compared to binary scaling of pp collisions at the same energy (up to a factor of 4) in the 10% most central Pb-Pb collisions. There is a centrality trend of suppression, and a weaker suppression (down to a factor of 2) in semi-peripheral (50-80%) collisions is observed. The suppression of electrons in this broad p(T) interval indicates that both charm and beauty quarks lose energy when they traverse the hot medium formed in Pb-Pb collisions at LHC.771467481CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoThe ALICE Collaboration would like to thank all its engineers and technicians for their invaluable contributions to the construction of the experiment and the CERN accelerator teams for the outstanding performance of the LHC complex.

Constraints on jet quenching in p-Pb collisions at root s(NN)=5.02 TeV measured by the event-activity dependence of semi-inclusive hadron-jet distributions

CNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOThe ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high-transverse momentum trigger hadron in p-Pb collisions at root s(NN) = 5.02TeV. Jets are reconstructed from charged-particle tracks using the anti-k(T) algorithm with resolution parameter R = 0.2 and 0.4. A data-driven statistical approach is used to correct the uncorrelated background jet yield. Recoil jet distributions are reported for jet transverse momentum 15 < p(T,jet)(ch) < 50 GeV/c and are compared in various intervals of p-Pb event activity, based on charged-particle multiplicity and zero-degree neutral energy in the forward (Pb-going) direction. The semi-inclusive observable is self-normalized and such comparisons do not require the interpretation of p-Pb event activity in terms of collision geometry, in contrast to inclusive jet observables. These measurements provide new constraints on the magnitude of jet quenching in small systems at the LHC. In p-Pb collisions with high event activity, the average medium-induced out-of-cone energy transport for jets with R = 0.4 and 15 < p(T,jet)(ch) < 50 GeV/c is measured to be less than 0.4 GeV/c at 90% confidence, which is over an order of magnitude smaller than a similar measurement for central Pb-Pb collisions at root s(NN) = 2.76 TeV. Comparison is made to theoretical calculations of jet quenching in small systems, and to inclusive jet measurements in p-Pb collisions selected by event activity at the LHC and in d-Au collisions at RHIC.78395113CNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOSem informaçãoSem informaçãoSem informaçãoAgências de fomento estrangeiras apoiaram essa pesquisa, mais informações acesse artig

Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at root s=7 TeV

Sem informaçãoTwo-particle angular correlations were measured in pp collisions at root s = 7 TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon-baryon and anti-baryon-anti-baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This effect is interpreted in the context of baryon production mechanisms in the fragmentation process. It currently presents a challenge to Monte Carlo models and its origin remains an open question.778117Sem informaçãoSem informaçãoSem informaçãoFunded by SCOAP3
