Técnicas de análise multivariada são aplicadas aos dados de ar superior coletados em Petrolina com o objetivo de identificar fatores físicos na atmosfera para janeiro de 2004, mês chuvoso no semiárido brasileiro. As chuvas são frequentes na área de Petrolina a partir do dia 10, associadas a ventos em superfície fracos e com direção variável. Na média troposfera o teor de umidade é muito baixo nos dias sem precipitação, em contraste com o teor de umidade elevado nos dias chuvosos. A aplicação da análise fatorial de componentes principais aos dados de ar superior resulta em um modelo com três componentes, retendo 96% e 93% da variância total dos dados no nível de 850 hPa e 500 hPa, respectivamente. O primeiro fator retido para cada nível isobárico é associado à advecção horizontal. No nível de 850 hPa, com 45% da variância total explicada, o fator é relacionado a advecção de temperatura pela componente meridional do vento; no nível de 500 hPa, com 46% da variância total explicada, ele está ligado a advecção de umidade pela componente zonal do vento. A aplicação da análise de agrupamentos aos fatores retidos possibilita identificar quatro grupos no nível de 850 hPa: os Grupos 1 e 2, formados por dias sem registro de chuva, e os Grupos 3 e 4, formados por dias com precipitação. No nível de 500 hPa são identificados três grupos, com características similares às dos grupos do nível de 850 hPa. ABSTRACT Multivariate analysis techniques are applied to upper air data collected in Petrolina aiming to identify physical factors in the atmosphere on January 2004, a rainy month in the Brazilian semiarid. Starting on the 10th, rainfall is frequent in the Petrolina area associated with weak and variable surface winds. In the middle troposphere the moisture content is very low in rainless days, in contrast with high moisture content in rainy days. Factorial analysis by principal components applied to upper air data results in a three component model, retaining 96% and 93% of the total variance in the data, at the 850 hPa and 500 hPa levels, respectively. Both isobaric levels have the first retained factor associated with horizontal advection. At 850 hPa, with 45% of the total variance explained, the factor is related to temperature advection by the meridional wind component, while at 500 hPa, with 46% of the total variance explained, the factor is related to moisture advection by the zonal wind component. Cluster analysis applied to the retained factors allows identification of four groups at the 850 hPa level: Groups 1 and 2 are formed by rainless days, while Groups 3 and 4 are comprised by rainy days. Three groups were identified at the 500 hPa level, whose characteristics are similar to those of the 850 hPa groups.

Published: March 2021

<p>Thin film copper-based RTD still has a low TCR. Hence, plating a Cu-based RTD with nickel will develop a higher TCR. TCR is the sensitivity of RTD’s value in response to temperature change. The experimental design in constructing Cu/Ni thin film by using the electroplating method with a concentration of solution and electrode spacing’s variation has been done. Electroplating is performed with a concentration of solution and electrode spacing’s variations<em>.</em> Electroplating processed by limiting DC voltage to 6 volts. Electrolyte solutions composition were NiSO4, Ni2Cl2, H3BO3 and aquades. Concentrations of solutions can be varied by changing NiSO4 and Ni2Cl2 masses. Based on these concentrations of solutes and electrode’s spacing, this research used 15 samples. Thickness, thin-film resistance, and temperature sensor test are performed to each sample. The purpose of thickness test is to measure nickel plates which were formed from the electroplating process. Thin-film resistance test performed to measure sample resistance changing to the electroplating process, and the temperature sensor test was performed to measures the sample’s sensitivity in responding to temperature changes. This research’s result shows the greater the concentrations of solutes used for copper electroplating, the thicker nickel plates will form. This condition makes its resistance’s value decreasing.</p><p><strong>Keywords:</strong> thin layer resistance, concentration of the solution, electrode distance, electroplating, thin layers of Cu / Ni, RTD, modules</p>

Aim. This study was aimed at developing biocompatibility of extracorporeal components due to the use of «adaptation composition» (AdC), reducing the negative impact of perfusion on the state of red blood cell due to the use of fructose-1,6-diphosphate (FDP) to decrease intraoperative hemolysis and tissue hypoxia.
Material and methods. The study included 225 patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). The first group included patients who underwent surgery with the treatment of an extracorporeal circuit by AdC, the second group included patients who were administered the drug with the active substance FDP, the third group was the control group. The oxygenator was treated with AdC and PDF was administrated according to the protocol. Patient blood was sampling for complete blood cell count (CBC) and blood smears were at 4 stages of surgery: before CPB, at 10 min. CPB-time, at 60 min. CPB-time (rewarming stage) and after separation from CPB. Several parameters were studied: plasma free hemoglobin (plfHb), the erythrocytes osmotic, mechanical resistance of erythrocytes, erythrocyte membrane permeability (EMP), acid hemolysis, the blood smears were stained according to Pappenheim.
Results. The best erythrocyte indices, hemolysis, osmotic, mechanical, acid, urea resistance of erythrocytes were observed in the groups where fructose-1,6-diphosphate and «adaptation composition» were used. At the preoperative stage, hypophosphatemia was detected in 16.8% out of 225 patients and 26.6% out of 225 patients have a clear tendency to ones. After CPB, there was no hypophosphatemia in the group where fructose-1,6-diphosphate was administered. The higher peripheralization of reticulocytes, echinocytes, and spherocytes was observed in the control group after perfusion.
Conclusion. The use of AdC and FDP during CPB helps to reduce hemolysis and the better state of erythrocytes.
Cardiopulmonary bypass (CPB) can negatively affect the state of red blood cell. The effect of fructose-1,6-diphosphate and «adaptation composition» on the state of erythrocytes during perfusion was studied.

Published: March 2021

Summary. Purpose of the study: to assess the effect of motor disorders on the quality of life of elderly patients with comobility of Parkinson's disease and frailty and to evaluate the effectiveness of their correction by means of physical therapy.
Material and methods. 57 elderly people with diagnosed Parkinson's disease in combination with frailty were examined. They were divided into two groups: 1 (practiced according to the principles of polyclinic rehabilitation) and 2 (practiced according to a developed program of physical therapy, which was created from the point of view of a patient-centric model of rehabilitation, taking into account the specifics of each polymorbid state with the use of functional training, massage, ergotherapy, correction food). In the course of physical therapy, we consistently achieved individual short- and long-term goals of rehabilitation in the SMART format. The effectiveness of the program was assessed by the dynamics of the MDS Unified Parkinson's Disease Rating Scale, Schwab-England, PDQ-39.
Results. The examined persons were found to have significant motor disorders, deterioration in the activity of everyday life and everyday activity and, as a consequence, a decrease in the quality of life. The developed program of physical therapy, created from the point of view of a patient-centric model of rehabilitation with the use of functional training, therapeutic exercises, massage, ergotherapy, nutrition correction, revealed a statistically significant better effect on the indicators of motor functions, the state of daily and household activity and the quality of life in comparison with the general polyclinic program. for all studied indicators (p <0.05).
Findings. Elderly patients with comorbidity of Parkinson's disease and senile asthenia require the development of individual programs of physical therapy, taking into account and correcting the specificity of each disease, which increases the overall effectiveness of rehabilitation.
