Analytical representation of bimodality in bivariate distribution of chain length and chemical composition of copolymers

2022

Abstract Tuning the bimodality of microstructural features in polymers has provided novel properties and applications. A classic example is to overcome the trade-off between processability and mechanical properties in polyolefins. A recent example is to decrease the interfacial tension in blending incompatible polymers. Therefore, the development of a bimodality index (BI), especially for the chain length distribution (CLD) and the chemical composition distribution (CCD), is crucial for the quantitative design of materials. This study introduces quantitative expressions for the bimodality of univariate CLD on the linear scale, and CCD. Moreover, we develop a bimodality criterion for bivaria…

Use of autologous conditioned serum (Orthokine) for the treatment of the degenerative osteoarthritis of the temporomandibular joint. Review of the li…

2012

Objectives: Treatment of osteoarthritis (OA) using autologous conditioned serum (ACS) has become in recent years an alternative to consider in the approach of the degenerative joint disease of the knee. There is no support in the literature for the use of ACS for the treatment of OA of the temporomandibular joint (TMJ), although the promising results obtained in human patients with knee joint disease as well as in animal studies are opening the way for its use at the TMJ. The aim of this paper is to conduct a review of the published literature regarding the use of the ACS for the treatment of OA in humans, considering the level of scientific evidence, and following the principles of the evi…

A weighted logistic regression for conjoint analysis and Kansei engineering

2007

Customer needs for emotional satisfaction are increasingly being considered by product and service designers. While several existing methods such as conjoint analysis (CA), Kano model and quality function deployment support the translation of customer requirements into technical specifications, researchers are now working to develop methods aimed at integrating affective aspects into product design. Kansei engineering (KE) is a design philosophy that considers customer perceptions and emotions by adopting a multi-disciplinary approach. CA is a useful tool within a KE project. This article presents a methodology for conducting a KE project in early development phases. This methodology is bas…

Gaining Competitive Advantage through Standardization and Differentiation of Services

2015

The goal of the paper is to study the question of whether or not differences between cultural groups influence the decision of a consumer wishing to avail himself of a particular service. Therefore we have developed a semiotic extension of the means-end approach as the theoretical basis for elaborating a solution to this problem. The conjoint analysis specifies the results of the meansend analysis.

Economic Allocation in Life Cycle Assessment The State of the Art and Discussion of Examples

2012

Summary This article examines methods for analyzing allocation in life cycle assessment (LCA); it focuses on comparisons of economic allocation with other feasible alternatives. The International Organization for Standardization's (ISO) guideline 14044 indicates that economic allocation should only be used as a last resort, when other methods are not suitable. However, the LCA literature reports several examples of the use of economic allocation. This is due partly to its simplicity and partly to its ability to illustrate the properties of complex systems. Sometimes a price summarizes complex attributes of product or service quality that cannot be easily measured by physical criteria. On th…

Anatomia clinica del sistema articolare del piede

2006

From a semantic point of view the word “ankle” and “ankle region” are not synonyms as “ankle” identifies all the components of the ankle joint while “ankle region” identifies the ankle joint as well as every structures in the region, form the surface level to the skeletal one. The articular system of the foot is formed by thirthyfour synovial joints, seventeen of which have complementary curvilinear articular surface, the remaning seventeen having plane joints. The rounded surface joints are: the talonavicular joint (a spheroidal joint that is part of the transverse tarsal joint), the “anatomical” subtalar joint ( a saddle joint), five ellipsoid (or condylar) joints and ten, ankle and inter…

PRENATAL DEVELOPMENT OF TEMPORO-MANDIBULAR JOINTS: STATE OF ART

2017

The aim of this work is to analyze the state of the art of temporo-mandibular joint (MJ) to understand the varoius stage of the development of the same during embryogenesis. Various theories have been analyzed, such as the formation of apoptotic or the important role of growth factors, or the Valencia et studies in which are analyzed to numerous articular diseases in various stage of development. By the aforementioned studies show that many factors, of a different nature, are to be involved in the prenatal developlment of this important joint.

Non-Hermitian Hamiltonians in Quantum Physics

2016

This volume collects the selected contributions presented at or inspired by the15th International Workshop on Pseuso-Hermitian Hamiltonians in QuantumPhysics(PHHQP15), held in Palermo, Italy, from May 18 to 23, 2015. Thisworkshop was the 15th in the series of international meetings that was started in2003. These meetings were mainly attended by mathematicians and physicistsinterested in the study of non-Hermitian operators and Hamiltonians, and in theirphysical applications. About 80 mathematicians and physicists attended the 2015Workshop in Palermo.

Comportamento flessionale di nodi esterni in calcestruzzo fibrorinforzato

2010

A softened strut-and-tie macro model able to reproduce the flexural behavior of external beam-tocolumn joints with the presence of horizontal and vertical steel bars, including softening of compressed struts and yielding of main and secondary steel bars, is presented, to be used for the pushover analysis. The model proposed is able to calculate also the flexural response of fibrous reinforced concrete (FRC) beam-to-column sub-assemblages in term of a multilinear load-deflection curves. The model is able to take into account of the tensile behavior of main bars embedded in the surrounding concrete and of the softening of the compressed strut, the arrangement and percentage of the steel bars,…
