Influence of Inter- and Intra-Batch Variability on the Sample Size Required for Demonstration of Equivalent Microstructure of Semisolid Dosage Forms
2020
Inter- and intra-batch variability of the quality attributes contribute to the uncertainty for demonstrating equivalent microstructure of post-approval changes and generic/hybrids of semisolid topical products. Selecting a representative sample size to describe accurately the in vitro properties of semisolids and to reach enough statistical power to demonstrate similarity between two semisolid topical products is currently challenging. The objective of this work is to establish the number of batches and units per batch to be compared based on different inter-batch and intra-batch variability to demonstrate equivalence in the physical characteristics of the products that ensure a similar mic…
Competitividad Del Sector Manufacturero En Ammrica Latina Tendencias Y Determinants (Competitiveness of the Manufacturing Sector in Latin America Tre…
2014
Spanish Abstract: Tras analizar conjuntamente la evolucion de las exportaciones de los principales paises latinoamericanos en la ultima decada y examinar caso a caso los determinantes del desempeno de cada pais, este estudio concluye que la competitividad del sector manufacturero en la mayoria de los paises de la region ha disminuido a partir de 2007 hasta el 2012, despues de evolucionar de manera relativamente favorable entre el 2002 y el 2007. Este deterioro reciente, que ha sido mas marcado en paises como Brasil y Colombia, esta relacionado con el mantenimiento de un tipo de cambio real apreciado, elevados costes laborales y un insuficiente avance de la productividad de la mano de obra. …
Ankle Foot Orthoses with Wire Insertion
2013
The objective of the work is to present some researches regarding the virtual modelling of external medical devices with wire insertion. Ankle foot orthoses are used to correct and prevent different disfunctions of the human body and also in athlets recovery. The research is motivate by the problems appeared using this medical devices: durability issues, patient confort, manufacturing costs, lightweight, flexible access to shoes, inexpensive, readily available. These issues depends of the wey design, manufacturing technology, materials used, patient behavior, skills manufacturer. Wire insertion in polypropylene is a new approach of orthoses materials.
Study regarding the influence of material type on economic objectives in MEx fabrication
2021
Material Extrusion has been used extensively as an additive manufacturing technology for a variety of applications like visual models, functional prototypes, tooling components, patterns for castings, and final parts. The current research paper proposes a study on the material type influence on economic objectives in material extrusion fabrication of complex assemblies. Three economic objectives have been analysed, namely, estimated fabrication time, material usage and material cost, whilst two commercial additive manufacturing machines have been considered for the simulation. Cura and ZSuite slicing software were used for the generation of Gcode and project files. Five filaments were selec…
Implementation and optimization of the properties of a sandwich structure in biobased materials (fibres and Hemp wood) with an expanded polystyrene m…
2017
Due to the rapidly improving functionality of building materials, and increasingly complicated human resource management issues, the traditional cement-based building materials of the past are becoming less and less desirable.These outdated materials are being replaced by new structures of wall that better optimize choices of materials and their layouts. In this study, we propose a multi-function structure to be the unit of a typical wall (individual house), which can be produced via the use of inexpensive materials and classic manufacturing processes. To achieve this, we chose the renewable agricultural source of the hemp plant (hemp yarns and hemp shive particles), along with recycled exp…
The calculation of shadow prices for industrial wastes using distance functions: An analysis for Spanish ceramic pavements firms
2001
Abstract This paper deals with the calculation of shadow prices for two industrial wastes generated on their production processes by 18 firms belonging to the Spanish ceramic pavements industry. These prices are then used to calculate an extended productivity index which takes into consideration wastes going with the production of marketable goods. We follow the methodological approach first proposed by Fare et al. (The Review of Economics and Statistics 75 (1993)). A negative correlation is found between absolute shadow prices and wastes production intensity, reflecting a greater marginal cost of eliminating wastes for those firms using less contaminant production processes. Differences be…
Tool replacement with adaptive control in a non-stationary non-periodic stochastic process
1991
Abstract The problem of optimum tool replacement is studied in the case in which tool performance is characterized by progressive decay over time following stochastic laws. A control system is assumed which detects, continuously or at fixed intervals, the service state of the tool. Assuming that the service state of the tool affects the marginal cost of production, the latter is used in order to minimize the unit production cost for an unlimited production horizon. The replacement policy proposed is able to update itself in process by means of an iterative procedure which converges to a conditioned optimum. The effectiveness of such a policy is demonstrated analytically, and illustrative ex…
A sustainable phenolic compound extraction system from olive oil mill wastewater
2017
Abstract The reduction of environmental impact and the achievement of economic advantages based on by-product recovery is the aim of applying methodologies for phenolic compounds extraction from Olive Oil Mill Wastewater. Volume reduction of Olive Oil Mill Wastewater could generate important advantages in terms of waste disposal cost abatement and, in addition, reuse in the production of foods with health properties could lead to economic benefits. Despite the fact that literature shows that several techniques have been developed, few economic approaches have been presented. This paper assesses the economic feasibility of a system based on membrane filtration and reverse osmosis processes f…
