Biodegradable Zn-based alloys, particularly Zn-Mg alloys with the addition of alloying elements, have been intensively investigated aiming to improve both mechanical properties and corrosion behavior. Since such properties are strongly dependent on the alloy microstructure, any evaluation should commence on understanding the conditions influencing its formation. In this study, the effect of the solidification cooling rate on the microstructural evolution of Zn-1 wt.%Mg-(0.5 wt.%Ca, 0.5 wt.%Mn) alloys during transient solidification was investigated. The results show that the microstructures of both alloys have three phases in common: η-Zn dendritic matrix, intermetallic compounds(IMCs) Zn11Mg2, and Zn2 Mg in the eutectic mixture. MnZn9 and two Ca-bearing phases(CaZn11 and CaZn13) are associated with Mn and Ca additions, respectively. These additions are shown to refine the dendritic matrix and the eutectic mixture as compared to the Zn-1 wt.%Mg alloy. A correlation between cooling rate, dendritic or eutectic spacings was developed, thus permitting experimental growth laws to be proposed. Additionally, hardness tests were performed to evaluate the effects of additions of Ca and Mn. Experimental correlations between Vickers microhardness and secondary dendritic spacings were proposed, showing that the microstructural refinement and characteristic Ca and Mn based IMCs induce an increase in hardness as compared to the binary alloy.

There are a diversity and variability of oil producing plants and different extraction methods. These vegetable and essential oils are substances stored and released by plants from their fruits, leaves, flowers, bark and stem, being complete of plant origin that provides some benefits. In the plant these oils are also known as antioxidant substances, which have the function of natural protection. It is known that the extraction method has a strong influence on its quality and composition due to its variability and environmental conditions, besides possible adulteration. Oils that are rich in polyunsaturated fatty acids are the most relevant to the cosmetic industry but are most sensitive to oxidation. The oxidation of these oils generates what is known as rancidity, with the presence of smaller and undesirable molecules, thus reducing the quality of the oil beyond its nutritional value, making them harmful to human health. Stocking conditions, such as exposure to sunlight and heat, are major phenomena that accelerate the degradation of these oils. Infrared spectrometry with Fourier transform (FTIR) is a tool with potential to evaluate the degradation effect of vegetable oils. Infrared spectra of Almond (Prunus dulcis), Andiroba (Carapa guianensis aubl.), Copaíba (Copaifera langsdorffi) and Rosehip (Rosa aff. Rubiginosa) oils before and after exposure to sun light for 90 days were analyzed, with objective of evaluating the effect of the degradation on the composition of the oil, which were acquired in local commerce of the city Porto Velho. The spectra trends show the occurrence of oxidation, with the reduction of unsaturation, in addition to the fractionation of carbon chains and appearance of functional groups such as aldehyde and alcohol.

InVesalius is an open-source software for reconstruction of computed tomography and magnetic resonance images, which allows the user to make analysis and segmentation of virtual anatomical models. Physical models can be printed with the aid of rapid prototyping, giving the medical community a reliable instrument to help planning surgeries. To offer the user more control over the model, this work describes a methodology and tool developed for NURBS parameterization that provides mechanisms for adjusting the shape or even selecting a particular region of interest of the surface. Furthermore, the tool gives the option to export the final results of the process to a STEP file, which allows further edition in any well-known CAD software.

Background: The unaesthetic appearance of the female intimate area (vulva, “mound of venus” and perianal region) is a triggering factor of negative psychological responses, embarrassment, anxiety and insecurity in many women. Using rejuvenating equipment for vaginal structure or for the intimate area as a whole is already widespread in the literature, and High-Intensity Focused Ultrasound (HIFU) has proven to be very effective in the clinical practice of many professionals. This study, therefore, aims to describe the fundamentals and applicability that guide the use of HIFU in vulvar rejuvenation. Materials and Methods: Exploratory research was carried out, presented in a narrative review, to highlight the action of HIFU in female intimate rejuvenation. The review explored scientific articles published and available in the following databases: MEDLINE (Medical Literature Analysis and Retrieval System Online), PubMed (National Library of Medicine), SCIELO (Scientific Electronic Library Online), and LILACS (Latin Literature American and the Caribbean in Health Sciences). In addition, some clinical findings obtained through a retrospective analysis of medical records were added to describe the authors’ clinical experience in the use of Focused Ultrasound (HIFU) for vulvar rejuvenation. Results: We verified that the tissues of female external genitalia respond very well to the stimuli of the focused sound waves of the HIFU, being able to produce immediate and lasting results through isolated applications or in association with intradermotherapy or other therapeutic resources. Conclusion: We conclude that using High Intensity Focused Ultrasound aimed at vulvar rejuvenation is safely indicated and assures excellent aesthetic results at the end of the treatment because similarly to other treatment techniques, the thermal stimuli of HIFU are also able to produce an excellent therapeutic response in the dermal tissue of the female intimate area, promoting intense neocollagen
