ABSTRACT
Objective The non intrusive ultrasound combined with western medicine in the treatment of chronic prostatitis prostate/research and analysis of the effect of chronic pelvic pain syndrome.Methods96 cases of chronic prostatitis patients who were treated in our hospital from September 2016 to were randomly divided into the observation group, the control group 1 and the control group2.The observation group was treated with western medicine in the treatment of non intrusive prostate ultrasound;1 patients in the control group were given a single non intrusive prostate ultrasound treatment;control group 2 given a single treatment with Chinese and Western medicine.The clinical symptoms and NIH-CPSI scores were evaluated before and after treatment in each group.ResultsComparison between groups of patients before treatment NIH-CPSI score, no significant difference;after treatment, the NIH-CPSI score has decreased, there are obvious differences (P<0.05);the patients in the observation group were decreased significantly, the total score before treatment (26.21±2.20), the total score after treatment (11.77±1.90), there are obvious the difference (P<0.05).The treatment groups were compared with the efficiency, the total efficiency of observation group was 93.75%, the control group of 1 patients with the total effective rate was 75%, the control group of 2 patients with the total effective rate was 68.75%, there was significant difference in the treatment effect, with statistical significance (P<0.05).ConclusionNon intrusive ultrasound combined with western medicine in the treatment of prostate in compared with non intrusive ultrasound therapy and Western medicine alone in the treatment of prostate, has more significant treatment effect, should strengthen the clinical application and promotion.
ABSTRACT
Neste trabalho estuda-se a transferência de massa gás-líquido a partir de bolhas de ar para a água, geradas por um difusor de ar, em uma coluna de aeração, mudando a vazão de ar de 400 L/h a 2000 L/h, o nível de água de 0,50 m a 1,80 m, cujas taxas de aplicação superficial de ar variaram de 3,1 L/m².s a 15,4 L/m².s. Várias características hidrodinâmicas foram medidas, tal como a velocidade ascensional das bolhas de ar e seus diâmetros, fundamentais para verificar o coeficiente de transferência de massa que estão na literatura, usando um equipamento laser para velocimetria não-intrusiva. Após os estudos da transferência de massa, foi concluído que a vazão de ar entre 400 L/h e 800 L/h e o nível de água de 1,80 m apresentou a maior eficiência de transferência de massa, garantindo para estas medidas, dentro da coluna em estudo, maior quantidade de oxigênio dissolvido.
The present work is a study of the mass transfer gas-liquid from air bubbles into water, generated by a diffuser of air, in a column of aeration, changing the air flow from 400 L/h to 2000 L/h, the level of water from 0.50 m to 1.80 m, whose taxes of superficial application of air had varied of 3.1 L/m².s to 15.4 L/m².s. Several hydrodynamics characteristics were measured, such as the velocity range of the air bubbles and their diameter, fundamental to check the mass transfer coefficient that are in literature, by using a laser equipment for non-intrusive velocimetry. After of the study of the mass transfer, it was concluded that the air flow between 400 L/h and 800 L/h and the level of water of 1.80 m was the most efficient of mass transfer, guaranteeing for these measure, into of the column in study, most quantity of dissolved oxygen.
ABSTRACT
Objective To design a wearable physiological monitoring system for acquiring and monitor-ing vital signs non-intrusively and concurrently.Methods All bio-sensors were embedded in an elastic shirt for detecting physiological parameters with wearable technology.A patented respiratory inductive plethysmography technology was used to measure respiratory function,two sensors were woven into the jerkin around the patient's chest and abdomen.A three-lead,single channel ECG measures heart rate,and a three-axis accelerometer records posture and activity level.An NTC thermometer embedded in the shirt measures the body temperature.Results An elastic jerkin with embedded sensors that collect and continuously monitor respiration,cardiac,temperature,posture and activity signals was fabricated.Conclusion This wearable physiological monitoring system can record multiple parameters non-intrusively and concurrently.It can act as an useful platform for further researches.
ABSTRACT
Objective To design a system for monitoring pulse wave transit time (PWTT) in working condition non-intrusively and continuously. Method The system was composed of wireless ECG sensor and wireless pulse wave sensor which measure pulse wave signal from the temporal artery and ECG signal from body synchronously and calculates PWTT continuously. Result Both the wireless ECG sensor and the wireless pulse wave sensor were small sized and powered by button battery. And the accuracy of time synchronization about sensors was less than 1 ms. The calculated PWTT changed slowly with deep breathing. Conclusion The system works smoothly for continuous monitoring of PWTT in working condition.
