One of the problems in the care of coronary patients is accurately assessing the functional state of the myocardium. Contributions from Master ( 25, 26) , using the Test of electrocardiographic Effort constitute itself a doctrinal issue in evaluating the state of coronary sufficiency. However, results based seudonegativos Scherf and Schaffer ( 33 ) can be found in 20% , and even the same Master considered by over 50 % . Recent research by Simonson (34, 35, 36 ), reviews the impact should be taken into account also in seudopositivos results. Be remembered that if a Stress Test is negative , is no guarantee for exempting imminent post coronary insufficiency ( 12). With the introduction of Practice Ballistocardiography by Dock system (10 ) , ( 11) , it is possible to insist on this method to find out the exact behavior of the myocardium in patients with coronary disease.

In the competition of the lighting market, LED technology has stood out for excellent characteristics, one of which is the possibility of dimming, compared to other technologies. The dimming capacity allows to find the comfort zone with respect to two parameters, illuminance and correlated colour temperature (CCT). The present work provides a methodology to find comfort with respect to two variables, the level of illumination and the CCT. A controller with a simple structure, supported by Arduino, is proposed to control the above-mentioned variables of LEDs. The LEDs are located on a tape attached to a heat sink. In addition, the use of a light box as an environment for analysis is proposed. The design of this cubicle is based on literature. The controller has the possibility to regulate 12 different channels and the linearity between the PWM output and the illuminance was verified. The ...

El objetivo del estudio fue evaluar el efecto de tres protocolos de anestesia balanceada sobre las funciones vitales y el tiempo de recuperación en la ovariohisterectomía felina. Se utilizaron 32 gatas criollas mayores de seis meses (ASA I y ASA II). Los animales fueron distribuidos en tres grupos y recibieron una premedicación similar, pero con inductores diferentes: 3 mg/kg de propofol (n=11), 7 mg/kg de ketamina (n=11) y 5 mg/kg de tiletamina (n=10). Los tres protocolos de anestesia se mantuvieron con isoflurano (1.5% v/v). La monitorización exhaustiva de las constantes fisiológicas fue registrada cada 2 minutos (intra quirúrgico) y cada 4 minutos (posquirúrgico) utilizando un monitor multiparámetro. El efecto de los tres protocolos sobre las funciones vitales y el tiempo de duración se evaluó mediante un análisis de varianza y la prueba de Tukey (α = 0.05). Los protocolos...

HIV-associated neurocognitive disorder (HAND) is not a well recognized entity but has high prevalence and impact in individuals infected with HIV. The term HAND encompasses a spectrum of progressive central nervous system (CNS) involvement, ranging from asymptomatic neurocognitive impairment and minor neurocognitive disorder through to the most severe form of HIV-associated dementia (HAD). While the incidence of HAD has declined significantly with highly active antiretroviral treatment (HAART), the milder forms of HAND have increased. In this review, updated nomenclature and research case definitions to guide HAND diagnosis are described. Clinical manifestations, diagnosis and treatment recommendations are also outlined. Finally, while neurocognitive impairment is typically diagnosed with full neuropsychological evaluation, the interpretation of test results is based on comparing the pat...

Objective: To evaluate the relationship between uremic index (UI) and renal function measured by creatinine clearance (CrCl) in persons with normal renal function and in those with chronic renal failure (CRF), as well as to compare the renal function extrapolated from serum creatinine and that calculated with equations internationally recommended. Methods: A cross sectional study was conducted including patients attended in outpatient clinics at Hospital Cayetano Heredia in Lima from June 2018 to June 2019. Pearson’s correlation between UI and CrCl was calculated; comparison of means of UI, serum creatinine and standard equations was done by ANOVA and eta square. Results: the overall UI was 4.37 ± 4.99 mg/dl and correlated linearly with CrCl (r=-0.74, p=0.000). The UI and the log UI were significantly more predictive of CrCl than serum creatinine and the international equations used. ...

Purpose. This paper aims to test the hypothesis that the effect of production slowdown on labour demand can be muted by labour hoarding. Design/methodology/approach. This study adopts a production function approach, using data from Malta, a small state in the EU. Findings. The results confirm the hypothesis and indicate that firms are normally prepared to employ and dismiss more workers in the long run than in the short run. Practical implications. This finding has important implications for developed countries, including that labour hoarding can be of certain relevance in times of economic slowdown as shocks are absorbed by internal flexibility. Originality/value. The results of this study add on to the existing literature in two ways. First, this study compares two industries –manufacturing and financial services– for which the former sector received support to hoard labour after t...

The functional compounds present in food are essential to prevent certain types of cancer, so it is important to know how they vary in the food during storage. The study was conducted in the Puno region in 2019; the objective of the trial was to evaluate the behavior of functional compounds in two accessions of Isaño: Yana añu (purple-dark color) and Yellow pumpkin with purple eyes during storage at natural conditions 13 ºC and 65 % of relative humidity. The method used to determine the polyphenols was the one described by Folin-Ciocalteu; ABTS to determine the CAOX and visual titration with 2-6 Dichlorophenolindophenol to quantify the vitamin C content. The results show that the Yana añu accession has the highest polyphenol content and antioxidant capacity compared to the yellow pumpkin with purple eyes accession, being these values for polyphenols 24.90 and 15.89 mg AGE.g-1, which ...

In 14 women with cervical factor infertility functional postcoital tests preovulatory 30 days, with accurate counts of spermatozoa in mucus cervicaI and intrauterine contents were made. The values are compared with the breasts of 19 women, multiparous. A normal patient and two infertile were followed with serial through a full cycle. Exact quantification of mucus crystallization, made by a new method, proved to be a good criterion for evaluating the cervical penetrability. A intracervical level infertile group results were not significantly different from controls; a slight decrease of mobile sperm directional no practical value. By contrast, intrauterine level in infertile sperm group were detected in only 7 of the 30 cases with very low concentrations; in the control group were 18 of 19 cases. It emphasizes the value of intrauterine sperm count, much higher than intracervical tests. Th...

This master thesis is devoted to the state estimation of a particular form of PDE systems, coupled parabolic PDEs with spatial dependent coefficients. This form of PDEs represent some dynamic systems such as Tubular Reactors, Diffusion in lithium-ion cells and Diffusive Gradient in Thin Films sensor. Other methods for this problem use "Backstepping" observers, in which the estimation error system is transformed into another system that is stable, reducing the problem to calculate the Kernel functions making the transformation possible. In some cases this calculation is not simple, also the simulation in real time of the observer system, that is also a PDE, can be difficult. The method presented in this thesis uses the properties of the so-called Modulating Functions in order to estimate the states. The procedure con- sists of generating an orthonormal basis of functions that can represen...

This is a test of visual perception in which sheets containing novel scenes and situations of everyday life in schematic form and with total disregard of detail accessories are presented. The essential features of the situation are present only through proper arrangement of pieces of fine wire wool and photographed. The response achieved in a control group of 100 normal persons constituted by the type of response and fifteen schizophrenic patients compared. Eighteen have been classified schizophrenic types response to the sheets that differ from the normal response. The purpose of the research is to show the primary disorder prejudicativa noetic function in building the perceptual world in the schizophrenic. This is a preliminary report.
