Shape Memory Actuator: thermomechanical training and surface optimization of shape memory wires embedded in a polymeric matrix [PDF]

open access: yes, 2011
In the first part of my work I studied the mechanical and thermal behaviour of NiTi wires and strips in order to find the best training cycle to achieve a good compromise between transformation temperatures, recovery forces and phase reversibility ...

Flavonoid mixture analysis by matrix-assisted diffusion-ordered spectroscopy [PDF]

open access: yes, 2012
The structural similarity of flavonoids, often present in natural product mixtures, makes their analysis by NMR methods less than straightforward. This similarity is a dual problem for one of the most powerful NMR methods for mixture analysis, diffusion ...

Combined approach to strategic analysis of the financial condition of organizations

open access: yesВестник Северо-Кавказского федерального университета
Introduction. The matrix approach is one of the common analytical tools in economic science. Its application is not very limited, and it serves as a supplement to a number of other analytical tools.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Nonlinear analysis and control of chemical reactors [PDF]

open access: yes, 1997
This thesis carries out a detailed study of a nonlinear spectral theory that is useful for modeling and controlling chemical reactors. The motivation for this work originates from a few reports which have demonstrated in the past that the nonlinear ...

Influence of the Physico-chemical Characteristics of the Hybrid Matrix on the Catalytic Properties of Sol-gel Entrapped Pseudomonas fluorescens Lipase [PDF]

open access: yes, 2016
Lipase from Pseudomonas fluorescens (Amano AK) was immobilized using the sol-gel entrapment technique and sol-gel entrapment combined with adsorption on a solid support (Celite 545). The sol-gel matrices were obtained using as precursors ternary mixtures

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Effective theories of finite volume QCD [PDF]

open access: yes, 2008
Finite volume QCD close to the chiral limit cannot be described by chiral Perturbation Theory using the usual p-expansion when the correlation length of pions becomes larger than the size of the box.

The Role of Oral Controlled Release Matrix Tablets in Drug Delivery Systems [PDF]

open access: yes, 2012
Formulations that are able to control the release of drug have become an integral part of the pharmaceutical industry. In particular oral drug delivery has been the focus of pharmaceutical research for many years.
