Novel electrode structure in a DBD reactor applied to the degradation of phenol in aqueous solution

引用

Plasma Science and Technology 2017年第7期19卷 71-84页

Phenol degradation experimental results are presented in a similar wastewater aqueous solution using a non-thermal plasma reactor in a coaxial dielectric barrier discharge. The novelty of the work is that one of the electrodes of the reactor has the shape of a hollow screw which shows an enhanced efficiency compared with a traditional smooth structure. The experimentation was carried out with gas mixtures of 90% Ar-10% O2, 80% At-20% 02 and 0% Ar-100% 02. After one hour of treatment the removal efficiency was 76%, 92%, and 97%, respectively, assessed with a gas chromatographic mass spectrometry technique. For both reactors used, the ozone concentration was measured. The screw electrode required less energy, for all gas mixtures, than the smooth electrode, to maintain the same ozone concentration. On the other hand, it was also observed that in both electrodes the electrical conductivity of the solution changed slightly from ,-0.0115 S m^-1 up to -0.0430 S m^-1 after one hour of treatment. The advantages of using the hollow screw electrode structure compared with the smooth electrode were：（1） lower typical power consumption, （2） the generation of a uniform plasma throughout the reactor benefiting the phenol degradation, （3） a relatively lower temperature of the aqueous solution during the process, and （4） the plasma generation length is larger.

Developing Genetic Variability of Quinoa (<i>Chenopodium quinoa</i>Willd.) with Gamma Radiation for Use in Breeding Programs

引用

American Journal of Plant Sciences 2013年第2期4卷 349-355页

作者： Luz Rayda Gomez-Pando Ana eguiluz-de la Barra Cereal and Native Grain Research Program National Agricultural University La Molina Lima Peru

Quinoa (Chenopodium quinoa Willd.) is a staple food produced mainly by small-scale subsistence farmers in Peru’s highland. Dry seeds (cv. Pasankalla) were irradiated with doses of 150 Gy, 250 Gy and 350 Gy. In the M1 generation, the germination process was delayed with increasing radiation dose;seedling height, root length and leaf development were most reduced at 250 Gy and at 350 Gy, no plants survived. In M2, the maximum spectrum of chlorophyll mutations corresponded to 150 Gy and the maximum frequency to 250 Gy. The chlorine mutation was predominant, followed by xantha. Changes were registered for branch number, pedicel length, plant height, life-cycle duration, stem and foliage colour, and leaf morphology at the two doses, with improvements in plant type. More than one mutation per plant was found, especially at 250 Gy. In M3, the same spectrum of mutations was observed, along with a valuable change in grain colour.

Atmospheric-pressure dielectric barrier discharge generation by a full-bridge flying capacitor multilevel inverter

引用

Plasma Science and Technology 2017年第7期19卷 40-49页

作者： Rosendo PE?A-eguiluz José A LóPEZ-FERNáNDEZ Antonio MERCADO-CABRERA Bethsabet JARAMILLO-SIERRA Régulo LóPEZ-CALLEJAS Benjamín RODRíGUEZ-MéNDEZ Raúl VALENCIA-ALVARADO Allan A FLORES-FUENTES Arturo E MU?OZ-CASTRO Plasma Physics Laboratory Instituto Nacional de Investigaciones Nucleares Tecnológico de Estudios Superiores de Tianguistenco Universidad Autónoma del Estado de México

A new configuration of a resonant full-bridge flying capacitor multicell inverter has been designed and constructed with the aim of achieving an extended output voltage frequency range with low harmonic distortion and reduced semiconductor commutation losses. This configuration was tested as a power supply for two different coaxial dielectric barrier discharge reactors, one of them employed for electric characterization and the other one for inorganic compound elimination in an aqueous solution. Two different gas mixtures, 90% Ar-10% 02 and 80% Ar-20% 02, were individually supplied during the experiments; the results showed a high- efficiency removal of meta-cresol （m-cresol） to the order of 98%, which was obtained by adding more oxygen to the plasma gas mixture.

Colorectal Cancer Screening in a Spanish Town: Evaluation of Colonoscopy Preparation, Sedation by the Endoscopist and Screening Results

引用

Open Journal of Gastroenterology 2014年第5期4卷 208-215页

作者： Rebeca Higuera álvarez Raquel González Monasterio Fidencio Bao Pérez Pablo Ruiz eguiluz Gastroenterology Department San Eloy Hospital Bilbao Spain

Objective: The aim of this study is to evaluate the colonic cleansing preparation and colorectal cancer screening results in Sestao (Bilbao);and to verify the safety of endoscopist-controlled sedation. Materials and methods: A retrospective observational study of colorectal cancer screening using the immunological faecal occult blood test in a medium-risk population in this region, with colonoscopy being performed in the event of a positive result. The colonic cleansing preparation was administered in split doses;the second dose was administered 4 hours prior to colonoscopy. The quality of the preparation and lesion detection were evaluated. Sedation-related complications were analyzed. Results: Participation was high (4342 of 6896 people invited, 62.99%), with 309 subjects (7.12%) presenting a positive immunological faecal occult blood test. A high percentage of the 284 colonoscopies had optimal preparation: 276 (97.18%) had an adequate preparation. A total of 22 (7.91%) sedation-related complications were detected: only one (0.36%) was serious. A total of 140 high-risk adenomas were removed (47.13%) and 24 carcinomas were diagnosed (8.08%). Both these percentages are high. Conclusions: Split doses of colonoscopy preparation and reduction of the time interval between the second dose and the colonoscopy result in a high percentage of adequate preparation and lesion detection. Sedation by trained endoscopists is safe and effective. An immunological faecal occult blood test-based screening program is feasible and allows malignant and precancerous lesions to be efficiently detected and treated.

介绍了一种特殊的多电机多变流器系统(MMS)结构,即专为轨道牵引设计的单逆变器双电机结构。牵引设备必须具有良好的转矩响应,为了控制两台电动机的转矩,可以采用基于传统磁场定向控制(FOC)的协调控制结构。单逆变器双异步电动机传动系统可以提高机车性能,降低由内部和外部干扰产生的不良影响,对其系统性能与传统的机车传动控制系统的性能进行了比较。机车制造商已对仿真模型进行了确认。根据结果对这2种控制方式进行了性能分析,而且考虑了该牵引系统中的4种特性干扰。
