The results of a simple computational model for differential settling are presented illustrating the significant role that particle size distribution plays in collision frequency and sedimentation rate of particles in a quiescent environment. The model tracks a large number of particles（order 10;） with log-normally distributed diameters,as they settle at their Stokes settling *** collisions are detected and result in larger particles that fall more rapidly.A number of simplifying assumptions are made in the model in order to avoid empirical correlations for phenomena such as collision efficiency and particle *** simplifying assumptions were needed to isolate and quantify the role of the particle size *** concentration profiles indicate that,even in the absence of collisions, the standard deviation（σ;） of the particle size strongly influences the bulk mass settling rate as,for largerσ;, more mass is concentrated in larger,faster falling *** collision frequency is also a strong function ofσ;. For a given mass concentration the collision frequency first increases linearly with increasingσ;as greater variation in particle size leads to greater variation in particle velocity,and shorter times for particles to catch each *** largerσ;more mass is concentrated in larger particles,so,for a given mass concentration,there are fewer particles per unit volume,increasing the mean distance between the particles and reducing the collision *** implications of these results for sedimentation measurement using optical attenuation techniques are discussed.

Two pure hexagonal phases of titanium dioxide, anatase and rutile, were grown on c-cut Al2O3 substrates via pulsed-laser deposition by changing only the growth and annealing conditions, but without changing the substrate, target, or working gas. Purity of each phase was confirmed by x-ray diffraction, the quality of each film was studied using atomic force microscopy and scanning electron microscopy, and the interface between each substrate and film was studied using x-ray photoelectron spectroscopy. A binding layer of Ti2O3 was found to explain anatase growth under the very large lattice mismatch conditions.

介入心脏病学知识(一) 经皮介入电生理学

英国医学杂志中文版 2005年第1期8卷 47-51页

作者： Gerry c.kaye 唐恺

20世纪80年代以前，心脏电生理检查主要通过药物手段来验证某些心律失常的产生机制(mechanism)，以便指导药物治疗。后来，人们认识到抗心律失常药有其自身的缺陷，因而大力开展了非药物治疗技术，其中最突出的是射频消融和植入型除颤器。

AIM: To identify potential risk indicators for emerging adults transitioning to adult health care. BAcKGROUND: Without maturity, independence, knowledge and motivation to manage their diabetes and successfully transition to adult healthcare, a proportion of emerging adults will struggle, leaving themselves vulnerable to diabetes-related complications. METHODS: Fifty-three emerging adults (aged 17 - 19 years) recently transitioned from pediatric to adult healthcare were recruited. Data included demographic, glycated haemoglobin, Body Mass Index, base-line and 12-month data from four psychosocial measures: Problem Areas in Diabetes, Diabetes Empowerment Scale, Hospital Anxiety and Depression Scale and dichotomous questions from the Eating Attitude Test. Missed appointments were obtained from hospital records. RESULTS: No significant differences in age, gender, BMI and individual survey scales between three appointment groups. Median HbA1c in the Sat-1 group was 7% (53 mmol/mol), compared with 8.6% (70 mmol/mol) and 8.5% (69 mmol/mol) respectively in the Sat-2 and Unsatisfactory groups. A ROc curve analysis and classification tree analysis identified optimal threshold values for the survey scales and their linear combinations. These values were used to make comparisons across two appointment and three HbA1c status groups. The unsatisfactory appointment group was characterised by statistically higher proportions of participants with (1) a low score for empowerment alone or in combination (less) with perceived problems and (2) statistically higher perceived problems and anxiety scores. cONcLUSIONS: Findings suggest that diabetes self-care confidence, less perception of diabetes as a problem, could be a useful indicator of future appointment attendance. Similarly, depression levels could be a useful predictor of better metabolic control following transition. RELEVANcE TO cLINIcAL PRAcTIcE: This study offers an innovative use of existing metrics to identify at-risk emergin

Aim:?To explore the longer term blood glucose self-monitoring outcomes and frequency of monitoring for outpatients with diabetes type 1 after completion of the Dose Adjustment for Normal Eating (DAFNE) course. The hypothesis was that DAFNE outcomes would differ according to frequency of glucose ***:?A?sequential data-triangulation design using existing?baseline (T0) and 12-months (T12)?DAFNE course data and interview data from 12 randomly selected participants who had completed the course two years ago.?Results: Age range was 23 to 70 years with HbA1c 6.1% to 12.6% at T0?and 6.1% to 11.4% at T12. comparisons of HbA1c, PAID, HAD subscales?anxiety?and?depression,?and covariate data between T0?and T12indicatedsignificant reductions in the mean depression and PAID scores (both?P?corded their blood glucose less than three times or three or more times per day, changes were not significantly different. For both groups, the trend between T0?and T12?was downwards for change in mean blood glucose level and all survey scales. The proportion of all participants with T12?HbA1c at or below their T0?value was greater than 50% (Proportion = 69%, 95% cI: 56% - 79%) but only the highest HbA1c tertile group showed a significant difference (P?= 0.003). There was an average decrease in the incidence of hypoglycaemic events of 0.6 overall: The greatest change was for the high HbA1c tertile with a mean decrease of 0.8. The interview data suggested that DAFNE graduates experimented more with food, exercise, and insulin;gained knowledge;learnt personal body needs;increased awareness of blood glucose level;gained confidence and improved their quality of life. conclusions: There was insufficient evidence to conclude that frequency of blood glucose monitoring influenced metabolic control. However, people with type 1 diabetes who undertake the less restricted DAFNE approach to diabetes self-management can improve their qualit

Objective: To estimate recent temporal trends in delivery by cesarean during the past decade and the proportion of vaginal deliveries after prior caesarean in the United Kingdom. Methods: We conducted a cohort study using information from the General Practice Research Database. We identified all women with 1 or more deliveries between January 1990 and December 1999 and determined the method(s) of delivery. We estimated the proportion of women with vaginal delivery after cesarean in a subcohort who had at least 3 years of follow-up. Results: We identified 39,938 cesareans among 271,663 deliveries (14.7% ), with an increase from 12.5% in 1990 to 18.3% in 1999. The proportion of cesarean deliveries increased with age and increased over time in all age groups except women aged younger than 20 years. Among 26,480 women with a caesarean delivery between 1990 and 1996, 7,649 (28.9% ) had a subsequent delivery. The proportion of vaginal delivery after prior cesarean decreased from 45% in 1991 to 37% in 1999. conclusion: cesarean deliveries increased as a proportion of all deliveries in the United Kingdom during the past decade, and the proportion of vaginal delivery after prior cesarean decreased. Still, the proportion of cesarean deliveries is lower and the proportion of vaginal deliveries after prior cesarean is higher in the United Kingdom than in the United States.

报道了两个稻瘟菌株cH63和TH16的杂交后代在36个水稻品种上的致病性分离、遗传分析以及无毒基因组成的分析结果。78个子囊孢子菌株中呈现显著的致病性分离,共出现71种致病类型,在不同品种上分别出现1∶1、1∶3、3∶1、1∶7、1∶15和15∶1等的无毒性/毒性分离,表明供试菌株对不同品种的无毒性/毒性是一个或多个基因控制的。遗传学分析结果表明,亲本菌株对不同品种的无毒性/毒性控制存在多种类型。菌株cH63对品种K59(Pi-t)、中98-18、特特普、T641、c102TTP(Pi-4)、c101TTP6、ENo.11、农虎6号、c101PKT(Pi-4a)、c105TTP-1(Pi-4)、中156和中98-19分别持有1个无毒基因;对品种1461选、6392选、麻谷泰引1号、Lemont、宫崎7号、Vandana、长香稻、青珍8号和珍优3号分别持有2个无毒基因;对于品种草笛(Pi-k)、品种20中-1、c104LAc(Pi-1)、c103TTP(Pi-1+1b)、K3(Pi-kh)、梅雨明(Pi-km)和东农363分别持有2个以上无毒基因;亲本菌株对于品种四丰43、珍龙13、c101LAc和20中-2分别持有2个无毒基因,关东51、欧244持有2个以上的无毒基因,但因亲本菌株对品种的致病型一致,难以判断控制菌株对品种非亲和性的基因来源。
