Chronic wound management; surgical therapy and complementary nursing with Manuka honey

Objectives. This study aims to analyze the evolution of chronic wounds treated both surgically and by complementary nursing using Manuka honey. The parameters monitored were: presence/persistence of bacterial infection, the duration of healing, the recovery period and the patients\u27 quality of life. Materials and Methods. The study group and the control group each consisted of 10 patients, aged between 50-60 years, with chronic wounds of various etiologies but without other significant systemic pathologies. Data collection was carried out through anamnesis, physical examination and analysis of medical documents. Results. In the study group, the depth of the wound was reduced rapidly and significantly, with complete epithelialization after about four weeks. In the control group, the wound was completely healed by classical treatment, but in eleven weeks and in the form of an unaesthetic keloid scar. The recovery period of a chronic wound appears to be significantly influenced by the use of Manuka honey. Conclusions. Future studies on large groups of patients need to verify the potential therapeutic properties of this compound (anti-inflammatory, antibacterial, antifungal, antioxidant, autolytic debridement, etc.), as well as its adjunctive contribution to wound dressing (maintaining a moist environment and reducing trauma and unpleasant odors)

The Use of Infrared Spectroscopy in the Investigation of Urolithiasis Ulilizarea spectroscopiei în infraroşu pentru investigarea urolitiazei

Abstract Infrared (IR) spectroscopy is a modern physical-chemical method suitable for the investigation of kidney stones composition. The application of this method in our wor

Psychological risk factors for road safety

AbstractThis meta-analytic study examines the latest psychological research focusing on road safety on the four strategic directions proposed by domain practitioners: 1. personality characteristics in young drivers, 2. ageing population and road traffic, 3. relationship between driver personality and accident producing and 4. national profiles of drivers. This study aims to advocate in support of the idea that the Romanian road safety strategy (involving road campaigns education) must take into account the complexity of the relationship between an psychological risk factors (individual's personality, age, national profiles of drivers) and behavior in traffic

A review of mental models research in child-computer interaction

AbstractResearch in cognitive science, science education, and developmental psychology has long investigating how children, based on their everyday experience, construct mental models of the world they live in. This paper provides a review of the research investigating the nature of mental models in the context of child-computer interaction, review elicitation techniques used within the field, and discusses its potential to further inform the design process. Exploring children's mental models of new technologies may bring about some further understanding in their cognitive and conceptual development, thus promting parents and teachers to guide them in exploring the new technological environment

Synthesis and Stability of the Strontium Cobaltite Thermally Treated in Air

This paper reports, the studies on chemical transformations at thermal treatment of a mixture of SrCO3 and Co3O4 corresponding to stoichiometric ratio of SrCoO3 compound. The mixture of raw materials was prepared by mechanical activation. Thermal analysis, X-ray diffraction and scanning electron microscopy were used for these studies. It was found that SrCoO3 forms at 930oC but is not stable and turn immediately into Sr2Co2O5 by eliminating of oxygen. This compound, Sr2Co2O5, is unstable and by increasing of the temperature decomposes in Sr3Co2O6 and cobalt oxide. At temperatures above the 1250oC, the samples melt and Sr3Co2O6 crystallizes from vitreous phase by cooling. </jats:p

Study on the Formation Mechanism and Sinterability of La1-x SrxCoO3-d (x = 0.1 - 0.3) Prepared by Mechanical Activation

In this work it was studying evolution of the reactions that occur at the formation of La1-xSrxCoO3-� from mixtures of La2O3, Co3O4 and SrCoO3, prepared by mechanical activation. It was found that distributions of the particles sizes after mechanical activation are unimodal and narrow. Thermal analysis shows that the reactions that occur under the temperature of 1000oC are dissociation reactions of the raw materials or of intermediate compounds formed in the process of mechanical activation. The first compound found, starting from 1000oC was LaCoO3, whereas Co3O4 and CoO were observed as secondary phases. By measuring the apparent density of the thermally treated samples, a good tendency to sintering was noticed. SEM images and EDX analyses allowed to highlight the high sinterability of the samples. </jats:p
