Investigation of biochars derived from waste lignocellulosic biomass and insulation electric cables: A comprehensive TGA and Macro-TGA analysis.

This study investigates the thermochemical decomposition and gasification performance of biochars produced from blends of waste lignocellulosic biomass and waste insulation electrical cables at varying temperatures. Characterization tests revealed changes, particularly in ash content (27.5 %-34 %) and elemental composition, with nitrogen content increasing notably in biochar samples compared to the original feedstock.

Characterization of the Effect of a Novel Production Technique for 'Not from Concentrate' Pear and Apple Juices on the Composition of Phenolic Compounds.

The consumption of 'not-from-concentrate' (NFC) fruit juices can be a convenient and enjoyable way to incorporate the nutritional benefits and flavors of fruits into one's diet. This study will focus on the effect of production of juices from apple and pear fruits, by using centrifugal decanter and tangential filtration, on the profile of polyphenols as a valuable source of bioactive compounds. Likewise, by-products from the juice industry were characterized in order to understand the high-value-added potential based on their composition of polyphenols.

In Vitro Cyto- and Genotoxicity Assessment of Antibacterial Paints with Triclosan and Isoborneol.

Surfaces with antimicrobial properties are gaining notoriety as an efficient method to avoid surface contamination. Self-disinfecting paints are a promising strategy towards cleaner indoor environments by preventing the colonization of walls with microorganisms. However, its widespread use needs an appropriate toxicological safety evaluation due to the potential for biological disturbance associated to its biocidal activity.

Oleaginous yeasts for sustainable lipid production-from biodiesel to surf boards, a wide range of "green" applications.

A growing world population and a growing number of applications for vegetable oils are generating an increasing demand for these oils, causing serious environmental problems. A sustainable lipid production is then fundamental to address these problems. Oleaginous yeasts are a promising solution for sustainable lipid production, but, with the current knowledge and technology, they are still not a serious alternative in the market.

Optimization of lipid extraction from the oleaginous yeasts Rhodotorula glutinis and Lipomyces kononenkoae.

The constant growing demand for vegetable oil for biodiesel and food is raising many environmental concerns about the sustainability of its production based on crops. Oleaginous yeasts show great potential to end with those concerns due to their high lipid productivity in small areas. To evaluate their productivity in lipids, an efficient and reproducible extraction process should be used.

Implementation of integration strategies between primary care units and a regional general hospital in Brazil to update and connect health care professionals: a quasi-experimental study protocol.

Background: Better communication among field health care teams and points of care, together with investments focused on improving teamwork, individual management, and clinical skills, are strategies for achieving better outcomes in patient-oriented care. This research aims to implement and evaluate interventions focused on improving communication and knowledge among health teams based on points of care in a regional public health outreach network, assessing the following hypotheses: 1) A better-working communication process between hospitals and primary health care providers can improve the sharing of information on patients as well as patients' outcomes. 2) A skill-upgrading education tool offered to health providers at their work sites can improve patients' care and outcomes.

Thermal comfort assessment of a surgical room through computational fluid dynamics using local PMV index.

Background: Studies concerning indoor thermal conditions are very important in defining the satisfactory comfort range in health care facilities.

Objective: This study focuses on the evaluation of the thermal comfort sensation felt by surgeons and nurses, in an orthopaedic surgical room of a Portuguese hospital.

Methods: Two cases are assessed, with and without the presence of a person.

Appendicitis: what does really make the difference between private and public hospitals?

Background: Appendicitis is one of the most common surgical emergencies and is also a time-sensitive condition. Delays in treatment increase the risk of appendiceal perforation (AP), and thus AP rates have been used as a proxy to measure access to surgical care. It is very well known that in Brazil there are big differences between the public and private healthcare systems.

Impact of the use of vessel sealing or harmonic scalpel on intra-hospital outcomes and the cost of thyroidectomy procedures.

Objectives: To analyze the operative time, length of hospitalization and cost, as well as the bleeding and pain observed during the postoperative period, of thyroidectomy procedures using vessel sealing, harmonic scalpel or the conventional technique.

Methods: Retrospective analysis of thyroidectomies performed between 2007 and 2010 using either the conventional technique or minimally invasive techniques involving vessel sealing or a harmonic scalpel. Gender, age, primary diagnosis and procedure type were analyzed.

Mammaplasty combining vertical and transverse approaches through a vertical incision.

An adjustable vertical marking is described for vertical mammaplasty in mild and moderate hypertrophy or ptosis of the breast. A vertical rectangular flap with the pedicle supported at the inframammary fold provides fullness for the upper or the lower pole of the breast. It is fixed over the pectoralis aponeurosis along the upper pole to the base of the pedicle.
