title: Conceptual and mathematical difficulties of the conventional model of damped oscillations

description: Abstract A mathematical study on the subject of damped oscillations is expounded, focused on the computation of the constants of the equation of movement, their mathematical meaning and their implications on the behavior of systems. Examples are given of the initial value method for computing the constants, both for free and damped oscillations. Algebraic expressions are deduced for the conventional damped model and they are comparatively discussed with those from Crawford's formalism. The meaning of the constants is discussed and answers are offered for questions frequently asked by students and professionals. The concept of secant exponential function is introduced, and the distinction between this function and the envelope of the equation of motion is established. Examples are given of systematic errors committed when constants are arbitrarily imposed, and their meaning and the mathematical reason is discussed. In the appendix, the general equation of damped oscillations is deduced and examples are given for all three possible cases of systems (overdamping, critical damping, and underdamped oscillations). The conventional model of damped oscillations is deduced as a particular case of the general equation.

title: Analytical Analysis and Experimental Validation of a Multi-parameter Mach-Zehnder Fiber Optic Interferometric Sensor

description: Abstract Here we report a simple analytical technique to model a Mach-Zehnder fiber optic interferometric sensors that allow us to predict and calculate via computer simulations parameters that are not easily obtained experimentally. This model was calibrated and compared with experimental data using a 120 mm sensor for measurements of temperature, refractive index and water level. For instance, we were able to calculate the effects on the cladding effective index caused by the variation of those physical parameters. Moreover, this analysis could further our understanding of such sensors and allow us to make predictions about their use in different applications and even their behavior with different sensing lengths.

title: Body fat percentage in adolescents from Curitiba-PR metropolitan region: reference data using LMS method

description: Abstract Percentile indicators, aided in its development by biomedical engineering, relative to body fat distribution in adolescents are able to help health professionals in better diagnosing overweight and obesity. The aim of this study was to calculate percentile values to body fat in adolescents aged between 12 and 17 years from the Curitiba-PR and its metropolitan region composed of 29 municipalities, having as reference method the dual energy x-ray absorptiometry (DXA) technology. After applying inclusion criteria for the adolescents, anthropometric measures of body fat and stature were taken, as well as evaluation of the body composition through DXA. The statistical analysis was grounded in the presentation of percentilic values developed by Cole and Green’s LMS method, where L stands for the skewness curve, M for the mean curve and S for the variance curve. In total, 390 boys were evaluated. The fat percentage values tend to show a decrease between the ages of 12 (22.8±5.1%) and 16 years (17.9±2.9%). Moreover, for the superior percentiles: 90th and 97th re-start to increase at the age of 17 after showing a decrease in the previous years. The L, M and S parameters, altogether with the percentiles created to evaluate body fat are interesting tools to tendency and evolution analyses, as well as to enable inferences to be made about the body composition of adolescents.

title: WCIP Method Applied To Modeling an L-Notched Rectangular Metallic Ring FSS for Multiband Applications and its Equivalent Structure

description: Abstract A frequency selective surface (FSS) with a unit cell containing of an L-notched rectangular metallic ring pattern that can be adopted for dual polarization applications is proposed and analyzed using the wave concept iterative procedure (WCIP). The parametric study of the FSS provides three FSS dimensions where their variation independently or simultaneously results in resonant frequencies tuning. They are the two dimensions of the L part of the FSS and its notch penetration and changing their values in the FSS allowed intervals gives rise to charts and equations based on polynomials determined by the use of least mean square method. Thus no need to software to determine the FSS resonant frequencies once the application is restricted to a specific FSS such as the L- notched rectangular metallic ring FSS for low cost FSS use. The presented synthesis approach is extended to the determination of the equivalent FSS structures based on non-coupled parallel metallic strips for the complex FSS structures of difficult comprehensive resonance sources. One FSS is manufactured and characterized. A good agreement is recorded when the WCIP results for the transmission coefficient are compared with the results of COMSOL Multiphysics software and measurement.

title: Adipose tissue is less responsive to food restriction anti-inflammatory effects than liver, muscle, and brain in mice

description: High caloric intake promotes chronic inflammation, insulin resistance, and chronic diseases such as type-2 diabetes, which may be prevented by food restriction (FR). The effect of FR on expression of pro-inflammatory and anti-inflammatory genes in adipose tissue, liver, muscle, and brain was compared. Male Swiss mice were submitted to FR (FR group) or had free access to food (control group) during 56 days. The liver, gastrocnemius muscle, brain, and epididymal white adipose tissue (WAT) were collected for analysis of gene expressions. FR attenuated inflammation in the liver, brain, and gastrocnemius muscle but did not markedly change inflammatory gene expression in epididymal WAT. We concluded that adipose tissue was less responsive to FR in terms of gene expression of pro-inflammatory and anti-inflammatory genes.

title: CD47 expression is decreased in hematopoietic progenitor cells in patients with myelofibrosis

description: Myelofibrosis (MF) is characterized by increased circulating hematopoietic progenitor cells (HPCs), abnormal cytokine levels, and the survival advantage of neoplastic progenitors over their normal counterparts, which leads to progressive disappearance of polyclonal hematopoiesis. CD47 is a surface glycoprotein with many functions, such as acting as a phagocytosis inhibitor of the expressing cell, that is increased in normal hematopoietic stem and progenitor cells mobilized into the blood and several human cancer-initiating cells, such as in acute myeloid leukemia. We compared CD47 expression in hematopoietic stem and progenitor cells of patients with MF and controls and found it to be decreased in progenitors of MF. Exposure of control HPCs to the cytokines transforming growth factor β and stromal-derived factor 1, which are important regulators of hematopoietic stem cell cycling and are overexpressed in patients with MF, did not modulate CD47 expression.

title: Adaptation patterns of winter wheat cultivars in agro-ecological regions

description: ABSTRACT: Multi-environment trials are commonly used to assess cultivar adaptation patterns under different environmental conditions and to help make effective cultivar recommendations for growers. An example of a multi-environment trial system used for cultivar recommendations is the Polish Post-registration Variety Testing System. A common approach in cultivar recommendations is to evaluate the adaptability of cultivars across, or for, specific trial locations. However, the locations of the trials and the fields where a farmer will grow a crop are hardly ever in the same place. Therefore, it would be better to group the trial locations into regions and give recommendations for the whole region. The aim of this study is to evaluate the grain yield adaptation patterns of 62 modern winter wheat cultivars in six agro-ecological regions of Poland for two crop management intensities over five growing seasons. The analysis of the grain yield data was performed separately for each intensity using single-stage approaches in linear mixed models. We ascertained that winter wheat yield variability was in the main determined by agro-ecological region and their interactions, and to a small extent by the cultivar effect. Cultivars Sailor and Linus were widely adapted to all agro-ecological regions studied for both crop management intensities. It is highly probable that these two cultivars will obtain high yield in all agro-ecological regions as well as with both crop management intensities studied. We observed high compatibility rankings between locations for both crop management intensities. High compatibility of the cultivar rankings in the trial locations also provides high precision when determining regions.

title: GRANULOMATOUS PERIORAL DERMATITIS WITH EXTRA-FACIAL INVOLVEMENT IN CHILDHOOD: GOOD THERAPEUTIC RESPONSE WITH ORAL AZITHROMYCIN

description: ABSTRACT Objective: To present a case of granulomatous perioral dermatitis (GPD) with extra-facial involvement and good response to short-term treatment with oral macrolide. Case description: A 9-year-old girl presented with exuberant GPD with extra-facial involvement. During follow-up, she received multiple ineffective therapies, but showed significant improvement of the lesions after the use of azithromycin for five days. Comments: GPD is an inflammatory dermatological condition represented by papulo-erythematous eruptions on perioral, nasal and periorbital regions, more prevalent in children and adolescents. It rarely extends to the genital region, trunk, and extremities, which characterizes its extra-facial manifestation. Its etiology is unknown, but it seems to have a correlation with the use of topical corticosteroids and other agents.

title: P’URHEPECHA IDENTITY CONSTRUCTION FROM THEIR OWN INTERCULTURAL BILINGUAL EDUCATION PERSPECTIVE

description: SUMMARY The "T’arhexperakua - Growing Together" Project emerges in two P’urhepecha primary schools in the centre-west of Mexico’s highlands as an initiative of their indigenous teachers. Due to the high ethnolinguistic vitality, pupils enter school as monolinguals. The common approach to teach nevertheless in Spanish only had yielded widespread school failure. Therefore, the teachers started to teach all content matters including maths, language and literacy in the native language to improve learning in 1995. In 1999 a small team of linguists, educationalists and anthropologists were invited by the schools to implement a study of the project. Subsequently, they engaged in a long-lasting collaboration to improve teaching and to develop an intercultural and bilingual curriculum that persists till today. This article reports on the curriculum development and its practice. It analyses two classes carried out entirely in the native language. The first one deals with the indigenous worldview of the concept of territory and the obligation of its defence. The second class mobilises the rich morphological system of P’urhepecha with its classifiers of size and shape to help learn how mathematical fractions work. Our classroom analysis shows in which way teaches develop a language and education policy that fosters linguistic and ethnic identity through the functionally successful use of P’urhepecha in the high prestige school environment.

title: LEIGH SYNDROME: A CASE REPORT WITH A MITOCHONDRIAL DNA MUTATION

description: ABSTRACT Objective: Leigh syndrome is a neurodegenerative disorder with an incidence of 1:40,000 live births. It presents wide clinical, biochemical, and genetic heterogeneity, but with homogenous neuropatoradiological alterations. There is no specific treatment, and the prognosis is reserved. This case report aimed familiarize health professionals with the disease. Case Description: A 16-month-hold girl who was followed in outpatient clinic due to axial hypotonia and delayed psychomotor development. Karyotype, auditory evoked potentials and ophthalmologic evaluation were normal. Evidence of hyperlactacidemia and hypocitrullinemia was detected in the patient. After performing brain magnetic resonance under anesthesia, hypotonia got worse, and the patient was hospitalized after an episode of cyanosis and apnea. The electroencephalogram showed no epileptiform activity. Neuroimaging revealed bilateral lenticular hyperintensity, especially in the putamen and in the left globus pallidus regions. Molecular analysis revealed an 8993T&gt;G (MT-ATP6) mutation in the mitochondrial DNA. Comments: Between 10 and 30% of individuals with Leigh syndrome have mitochondrial DNA mutations. The decompensation after anesthetic intercurrences is typically associated with neurological deterioration and, in this case, increased the diagnosis suspicion. It is important to alert for similar cases and to reduce invasive diagnostic tests if the diagnosis is suspected.
