A Multi objective inventory model for short food supply chains

2017

Over the past 50 years, vertically integrated multinationals dominated global food markets by providing huge product diversity at low prices. Such systems are characterized by long supply chains capable of achieving high cost efficiencies resulting from the use of cheap raw materials, high chemical inputs, industrial shelf-life extension processes, economies of scale and mechanization. This dominant position on the market, however, has been achieved at a heavy cost on the global environment, generated by massive food wastage, and by a steady supply of fossil fuels. For such reasons, global supply chains are considered unsustainable and new food systems are being promoted in order to replace…

De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe

2021

Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …

Desarrollo de un modelo predictivo de mortalidad a largo plazo y complicaciones relacionadas con la endoprótesis, en la reparacion endovascular de an…

2015

Desde el inicio de la reparación endovascular de aneurismas de aorta abdominal infra renal, la progresión de dicho tratamiento ha superado en numero al realizado anualmente mediante cirugía abierta convencional, en la mayoría de servicios de Cirugía Vascular. A ello ha contribuido principalmente la menor mortalidad operatoria los 30 días y al atractivo que supone para pacientes un procedimiento menos agresivo y para los profesionales, el ofrecer una alternativa en casos en los que la cirugía abierta sería inasumible por elevado riesgo. Sin embargo se pueden señalar dos puntos de controversia en dicha tendencia: -La menor tasa de mortalidad postoperatoria, puede hacer que se ofrezcan alterna…

Understanding the fluctuations of perceived authenticity in cultural tourism : an investigation of Bali and Alsace contexts

2022

The marketing of cultural tourism faces a dilemma between maximizing the economic return and nurturing the culture’s social functions. It needs to attract segments driven by cultural motifs, through a differentiation based on authenticity. Perceived authenticity changes over a time, but how it does remains elusive to researchers. This research investigated fluctuations of existential authenticity in cultural tourists in Bali. Participants were purposively and conveniently-sampled among visitors of cultural attractions. It comprised two stages: qualitative for building the model, and quantitative fortesting the variables. The first employed Grounded Theory interviewing 24 visitors, found the…

FMEA - BASIC CONCEPT IN PRODUCT QUALITY

2018

Failure modes and effects analysis (FMEA) is a systematic procedure for analyzing a system (the entire system or just an assembly, subassembly or component) to identify potential failure modes, causes and effects of each failure on system operation. A somewhat different definition was formulated by Goddard Space Flight Center (USA) : FMEA is a procedure whereby every credible way of defeating each item from the lower decomposition level to the highest level is analyzed to determine effects on the system and classify each potential way of failure according to the severity of its effect.

The Legend of Excellent Businessman. A Neuroethical Perspective

2019

If the question about the causes of the crises has generated a good deal of literature in Spain, the key issue in recent times has been how to create that tangible and intangible wealth that only companies can give. One of the proposals that specialists agree upon is to revitalise the business entrepreneurial spirit, presenting the entrepreneurs’ way of life as an attractive option, due to the good they produce and the social recognition they enjoy. Accepting the suggestions of the so-called “narrative turn”, the article analyses the virtualities of business narratives in order to enhance the role of entrepreneurs. To this end, the article aims to cover three stages: (1) narratives are nece…

Changes in the receptor profile of the lower urinary tract in the aging male

2004

Benign prostatic hyperplasia (BPH) is one of th e most common effects of aging in men. Epidemiologists estimate that about one quarter of all men over 50 years of age suffer from BPH-derived voiding symptoms. Future demographic developments, with higher relative shares of older people, will increase the socioeconomic impact of this disease. Polder et al. (1994) calculated for the Netherlands that the treatment costs of BPH will double by 2035. Office visits for BPH related symptoms increased in the USA from 1.4 million in 1990 to 6 million in 1995, reflecting the increased public awareness of the problem and the increased desire for treatment (Kaplan et al. 1996).

Identification and Experimental Validation of an Induction Motor Thermal Model for Improved Drivetrain Design

2017

The ability of an electric powertrain to perform according to mechanical specifications is equally important as assessing its thermal protection limits, which are affected by its electrical and thermal properties. Although rated parameters (such as power, torque, etc.) are easily accessible in catalogs of equipment producers, more specific properties like mass/length of copper winding, heat dissipation factor, etc., are not available to customers. Therefore, an effective selection of drivetrain components is limited due to the lack of sufficient data and the need to consult critical design decisions with suppliers. To overcome this limitation, we propose a method to estimate the temperature…

Objective: Radical prostatectomy (RP) is a frequent treatment for men suffering from localized prostate cancer (PCa). Whilst offering a high chance for cure, it does not come without a significant impact on health-related quality of life. Herein we review the common adverse effects RP may have over the course of time.Methods: A collaborative narrative review was performed with the identification of the principal studies on the topic. The search was executed by a relevant term search on PubMed from 2010 to February 2021.Results: Rates of major complications in patients undergoing RP are generally low. The main adverse effects are erectile dysfunction varying from 11 to 87% and urinary incont…
