High Performance 3D PET Reconstruction Using Spherical Basis Functions on a Polar Grid

2011

Statistical iterative methods are a widely used method of image reconstruction in emission tomography. Traditionally, the image space is modelled as a combination of cubic voxels as a matter of simplicity. After reconstruction, images are routinely filtered to reduce statistical noise at the cost of spatial resolution degradation. An alternative to produce lower noise during reconstruction is to model the image space with spherical basis functions. These basis functions overlap in space producing a significantly large number of non-zero elements in the system response matrix (SRM) to store, which additionally leads to long reconstruction times. These two problems are partly overcome by expl…

Recycling of almond by-products for intestinal inflammation: improvement of physical-chemical, technological and biological characteristics of a drie…

2020

Background: Almond skins are rich in bioactive compounds that undergo oxidation/degradation phenomena and are poorly soluble in water, reducing in vivo absorption and bioavailability, factors that influence the pharmacological activity of an active product. We developed a dried acetonic almond skins extract/cyclodextrin complex to improve extract solubility, dissolution rate and biological activity. Methods: A lyophilized acetonic almond skin extract was produced. To optimize complex formulation, phase solubility studies and complex characterization (absorption studies, differential scanning calorimetry (DSC), morphology, solubility studies) were performed. To evaluate a possible use in hea…

Mediation for resolving family disputes

2016

Nowadays the understanding of the institute of marriage and its importance in the society has changed. Marriage is no longer assumed to be a commitment for a lifetime. As the principle of equality has replaced hierarchy as the guiding principle of family law it gave more grounds for family disputes and it became socially acceptable to leave marriages that are intolerable or merely unfulfilling. The aim of this article is to suggest an alternative dispute resolution method-mediation as a worthy option for resolving family conflicts.

Implementation of the Comprehensive Approach. Leadership factors that influence the respect of Human Rights and Humanitarian Law

2020

The respect of Human Rights and International Humanitarian Law is linked to conflict resolution and recent experiences show that is not possible to prevent, manage or resolve a conflict only with military means, a Comprehensive Approach is essential and in this context leadership assumes a crucial role. The purpose of this study is to determine the leadership factors influencing the respect of Human Rights and International Humanitarian Law. The first research question focuses on the relevance of the Comprehensive Approach, while the remaining questions examine why it is so difficult to implement it and how its implementation could improve the respect for Human Rights and the cooperation be…

Towards the Learning Experience Technology Usability framework

2017

The availability of learning technology has increased over past decades; however, severe usability issues that cause adverse effects on the learning experience can be found in many available technologies. Learning solution usability is commonly evaluated by focusing on either technical or pedagogical usability and rarely both. This artificially separates the two important aspects of learning technology usability. This chapter provides a new framework for designing and evaluating learning solutions that synthesizes the above usability types to consider them a part of a complex and dynamic whole comprising of learning, technological design, content-related issues and context. The proposed Lea…

Spectroscopic and Structural Investigation of the Confinement of D and L Dimethyl Tartrate in Lecithin Reverse Micelles

2009

The confinement of D and L dimethyl tartrate in lecithin reverse micelles dispersed in cyclohexane has been investigated by FT-IR, polarimetry, electronic and vibrational circular dichroism (ECD and VCD), 1H NMR, and small-angle X-ray scattering (SAXS). Measurements have been performed at room temperature as a function of the solubilizate-to-surfactant molar ratio (R) at fixed lecithin concentration. The analysis of experimental data indicates that the dimethyl tartrate molecules are solubilized within reverse micelles in proximity to the surfactant head groups in the same way for the D and L forms. The encapsulation of dimethyl tatrate within lecithin reverse micelles involves changes in i…

Dictamen profesional sobre la fusión y escisión como extrategias alternativas en un grupo de sociedades

2021

This work is a professional, legal opinion which sets out two alternative strategies (merger by absorption and partial demerger) in order to bring together the different areas of activity of the various companies in a group of companies. The aim is to provide solutions to the questions raised by customers and, therefore, to set out clearly and simply the procedure to be followed in each of the strategies, weighing up the advantages and disadvantages from each of them

Life-based design for technical solutions in social and voluntary work

2012

The Social and Voluntary work sector operates outside the organised boundaries and systems of normal business, financial and government organisational institutions. My target during this research has been to develop an optimum solution for decision support towards committing and accepting resources in the Social Work and Voluntary sector. In initial part of this monograph, I have traced the history of Design Thinking from the time it was ‘art and craft’ until modern times where multiple approaches are tried, tested and implemented for solution development. For the actual application development, I have chosen the Life-based Design conceptual framework. Three design iterations were made in t…

A Novel Fast Volumetric Light Sheet Microscopy

2016

Fast noninvasive three-dimensional (3D) imaging is crucial for the quantitative understanding of highly dynamic biological processes. Over the last decades, several fluorescence microscopy techniques have been developed in order to provide a faster and deeper imaging of thick biological samples [1]. Within this framework, Light Sheet Fluorescence Microscopy (LSFM) has emerged as a powerful imaging tool for 3D imaging of thick samples ranging from single cells to entire animals [2,3].However, to obtain a 3D reconstruction either sample or microscope parts usually need to be moved limiting the acquisition speed and inducing possible interferences in volume recording. To solve this problem, he…

Dissolution and hydrolysis of fibre sludge using hydroxyalkylimidazolium hydrogensulphate ionic liquids

2014

The dissolution and hydrolysis of wet fibre sludge in ionic liquids (ILs) with different reaction conditions are performed in this study. Novel types of hydroxyalkylimidazolium hydrogensulphate ILs, [glymim]HSO4, [hemim]HSO4 and [hpmim]HSO4, are especially designed and aimed to combine the dissolution and hydrolysis of wet fibre sludge in a one-step pretreatment. The results were obtained based on the analysis of total reducing sugars (TRS) with the DNS method. The dissolution and hydrolysis of fresh wild horse chestnut fruit (Aesculus hippocastanum) with the same ILs were also carried out as a comparison reference. Since fibre sludge is cellulose based and horse chestnut fruit is starch ba…
