Advancing manufacturing processes research at NAMRC 46
2018
Research on manufacturing processes is further enriched and becomes stronger at the 46th North American Manufacturing Research Conference (NAMRC 46) at Texas A&M University, College Station, TX, USA. Manufacturing processes are tightly connected to innovation. They have been the key areas that support and influence a nation’s competitiveness and economy since the eighteenth century. As the primary driving force behind economic growth, manufacturing processes enable and facilitate innovative products realisation, ranging from heavy-duty machinery to smart home electronics. In the past centuries, they have contributed significantly to modern civilisation and created the momentum that driv…
New trends in manufacturing processes research
2019
Research on manufacturing processes is further enriched and becomes stronger at the 47th North American Manufacturing Research Conference (NAMRC 47) at Penn State University, The Behrend College, Erie, Pennsylvania USA. Innovation is fundamentally connected to products or processes: the former being rarer and more difficult to be obtained, the latter is definitively related to economy, competitiveness and welfare of a nation. Furthermore, the research and success in innovation of processes permit also the proposition of innovative products. Manufacturing processes engineering is of primary interest for industries and new challenges are faced every day in order to reduce costs, increase comp…

Random short sisal fiber biocomposites: Optimal manufacturing process and reliable theoretical models
2018
Although several works have been published in literature on agave fibers and their biocomposites, accurate information about the choice of both the fibers and the manufacturing processes that allow the user to optimize the biocomposites properties in terms of strength and stiffness are not yet available; also, no theoretical models that can be used for an accurate evaluation of the mechanical properties of these biocomposites, are reported.To this aim, the present work intends to give a contribution by considering green epoxy biocomposites reinforced by both short and discontinuous sisal agave fibers arranged in proper MAT-type fabrics. In particular, an optimized manufacturing process that…
Implementation of eco-sustainable biocomposite materials reinforced by optimized agave fibers
2018
Abstract Although several works have recently been published in literature about biocomposites, i.e. about composites with polymeric matrix reinforced by natural fibers, only a few articles have been devoted to the implementation of high performance biocomposites for structural and semi-structural applications. The present study aims to give a contribution by considering biocomposites obtained by using an eco-friendly partially bio-based epoxy (green epoxy) and sisal (agave sisalana fibers) obtained by a proper optimization process. Through a systematic experimental analysis, three different types of biocomposites obtained with a suitable manufacturing process, such as random short fiber bi…
Corrosion of stainless steel in food and pharmaceutical industry
2021
Abstract Stainless steels are widely used in the food and pharmaceutical industry because of their high corrosion resistance and superior mechanical properties. These features are crucial because produced foodstuffs and drugs must comply with high purity and quality standards. Just a proper selection of stainless steel grade can prevent corrosion phenomena that can be detrimental to the whole manufacturing process. Food/drugs production process phases will be here analyzed and discussed with a particular emphasis on the possible corrosion mechanism of stainless steels in those particular operating conditions. Recent advances on the methods to assess corrosion of stainless steels in food and…
Tiger nut and its by-products valorization: From extraction of oil and valuable compounds to development of new healthy products
2018
Abstract Consumer's growing demand for consumption of “Horchata de chufa”, a Spanish beverage produced from tiger nut tubers, has led to large-scale production of tiger nuts, and its subsequent processing for the food industry. Recent investigations clearly show that tiger nut is a valuable source of stable vegetable oils, rich in monounsaturated fatty acids, and phytosterols as well as high-added value compounds (proteins, carbohydrates, vitamins, minerals and bioactive compounds). Several conventional (Soxhlet) and alternative innovative (SC-CO2, enzyme, high pressure, etc.) extraction methods have been developed for the efficient recovery of tiger nut oil and high-added value compounds. …
Optimal manufacturing and mechanical characterization of high performance biocomposites reinforced by sisal fibers
2018
Abstract The increasing interest about eco-sustainable materials in the industrial production (automotive, civil construction, packaging), has led to the increase of the research works dealing with biocomposites. However, until now the most attention has been devoted to the development of short fiber biocomposites for non-structural applications, whereas only a few works have considered high performance biocomposites for structural applications. Consequently, the development of structural biocomposites from robust natural fibers, as sisal fibers, is a result expected from the scientific community, but not yet achieved. In order to give a contribution to the implementation of high performanc…
Metabolic flux understanding of Pichia pastoris grown on heterogenous culture media
2014
[EN] Within the emergent field of Systems Biology, mathematical models obtained from physical chemical laws (the so-called first principles-based models) of microbial systems are employed to discern the principles that govern cellular behaviour and achieve a predictive understanding of cellular functions. The reliance on this biochemical knowledge has the drawback that some of the assumptions (specific kinetics of the reaction system, unknown dynamics and values of the model parameters) may not be valid for all the metabolic possible states of the network. In this uncertainty context, the combined use of fundamental knowledge and data measured in the fermentation that describe the behaviour…
Ensuring the Consistency of Biosimilars
2017
Background: Biological products are subject to constant reappraisal by regulatory agencies and pharmaceutical companies once they have entered the market, since every improvement in their manufacturing process has the potential to alter the basic properties of these molecules. Methods: Narrative review focusing on scientific literature as well as legal documents from regulatory agencies. Results: Evaluating the impact of each manufacturing change of these drugs requires rigorous analyses in proportion to the anticipated risk of inducing more or less molecular micro-heterogenicity. There are currently more than 30 biosimilars of TNF-alpha blockers at different stages of testing, each with a …
