Background: Ring wear and loss may have important consequences for mark-recapture studies that aim to estimate survival trends. Our study quantifies the rates of wear and loss from a long-running colour-ringing project of the Eurasian Oystercatcher (Haematopus ostralegus) in the Netherlands. Methods: Our analysis included 8909 colour-ringed oystercatchers with 118,071 resightings, predominantly ringed and observed by citizen scientists. We quantified how ring wear and loss may vary with ring colour and age, and how this may impact resighting probabilities. We then determined how ring loss may impact survival estimates and resighting probabilities of mark-recapture models by simulating four scenarios of how citizen scientists may resight and report birds with lost colour rings. Results: Annual rates of colour ring loss averaged 2.5% compared with 1% for ring wear, but lost rings also had a higher reporting probability (31.2%) than worn rings (10.3%). Lost rings may not directly impact survival estimates since 50% of oystercatchers with lost rings could still be uniquely identified. Ring wear and loss rapidly increased between 10 and 15 years after ringing. Rates of ring loss were comparable amongst ring colours, but the wear rate appeared higher for red and white rings compared to other colours. Rates of ring wear and loss varied significantly amongst different regions in our study, which were characterised as having different habitat features. Differential rates of ring wear may have important implications for studies conducted over large geographical scales or of multiple species. Conclusions: Based on simulations of ring loss in our population, estimates of apparent survival may be 0.3–1.2% lower whilst the impact of ring wear was deemed even lower. We developed a table of recommendations containing advice for ring fitting, data collection, study design, and mark-recapture analyses, so that future colour-ringing studies can benefit from our experiences in collecti

In Process Particle Size Distribution Measurements and Control for Jet Milling Processes

第五届国际粉体检测与控制学术会议

作者： henk.G.Merkus Melvin Wong Brian Scarlett Particle Technology Group Delft University0f Technology Julianalaan 136 2628 BL DelftThe Netherlands

Among a number of measurement techniques,laser diffraction has the advantage to be a fast,non-intrusive and reproducible technique and has widely been used for particle sizing in a variety of particulate processes. Moreover,since particle shape information can be retrieved from the azimuthal scattered intensity,this technique can be also applied for shape measurement. This paper describes a new sensor technique using a CMOS pixel *** sensor,compared with the existing fixed ring detection array,has flexibility for the application of sizing and shape measurement,no alignment is required and thereby is robust in operation. This technique has been applied to measure the crystal particle size and shape in the crystallization processes. Some results are presented to address the feature using this technique.

Third Joint China/USA Chemical Engineering Conference

＜正＞Jet milling is often used when a well-defined particle size distribution is required. This process avoids excessive heat production as well as contamination of the product. This makes jet milling very suitable for processing of plastics, pharmaceuticals and food additives. The major disadvantage of the process is the very poor energy efficiency. In practice jet mills have to be operated below their maximum capacity in order to avoid the production of off-specification material, due to the operation disturbances. Therefore, it is important to automate operation with a real-time PSD instrument for quality control. A technique for in-line particle size measurement using laser diffraction is reported, which has been used to improve operation control of the jet mill grinding system. A CMOS pixel array sizer could be a more robust and flexible sizing sensor in this application than the exiting laser diffraction instrument.

AIM: To investigate feasibility and accuracy of near-infrared fluorescence imaging using indocyanine green: nanocolloid for sentinel lymph node (SLN) detection in gastric ***: A prospective, single-institution, phase I feasibility trial was conducted. Patients suffering from gastric cancer and planned for gastrectomy were included. During surgery, a subserosal injection of 1.6 mL ICG:Nanocoll was administered around the tumor. NIR fluorescence imaging of the abdominal cavity was performed using the Mini-FLARE™ NIR fluorescence imaging system. Lymphatic pathways and SLNs were visualized. Of every detected SLN, the corresponding lymph node station, signal-to-background ratio and histopathological diagnosis was determined. Patients underwent standard-of-care gastrectomy. Detected SLNs outside the standard dissection planes were also resected and ***: Twenty-six patients were enrolled. Four patients were excluded because distant metastases were found during surgery or due to technical failure of the injection. In 21 of the remaining 22 patients, at least 1 SLN was detected by NIR Fluorescence imaging (mean 3.1 SLNs; range 1-6). In 8 of the 21 patients, tumor-positive LNs were found. Overall accuracy of the technique was 90% (70%-99%; 95%CI), which decreased by higher pT-stage (100%, 100%, 100%, 90%, 0% for respectively Tx, T1, T2, T3, T4 tumors). All NIR-negative SLNs were completely effaced by tumor. Mean fluorescence signal-to-background ratio of SLNs was 4.4 (range 1.4-19.8). In 8 of the 21 patients, SLNs outside the standard resection plane were identified, that contained malignant cells in 2 ***: This study shows successful use of ICG:Nanocoll as lymphatic tracer for SLN detection in gastric cancer. Moreover, tumor-containing LNs outside the standard dissection planes were identified.

探讨生命伦理学的起源,并阐述了不同理论支持者的观点,发现无论准确的生命伦理学历史起源是什么,目前生命伦理学已经变成了一种真正的全球现象。它在全世界具有重要的意义,因为人类不仅仅是欧洲人或亚洲人,也是世界公民和一个全球道德共同体的成员。生命伦理学对任何地方、任何人都是重要的,并不是因为它是"拿来"的,而是因为它提供了一个普遍的框架去解释和管理正在经历的变化,这个变化包括了目前所有的国家和文化。然而,这个框架的解释和应用必须依据本土环境。因此,现代生命伦理学具有全球性和本土特征的特点。
