我对机械相机情有独钟

随着电子技术的迅猛发展，测光、过片、调焦，全由数码逻辑电路控制的所谓纯“智能相机”，十几年前还是身披神秘外衣的“尤物”，如今却已是“涓涓细流汇成江海了”。机械相机简直被这“洪流”席卷得风雨飘摇、渺无踪影！以致让许多人觉得，再加以时间洪流的无情裹协，机械相机会像20世纪一样，只能成为一段历史了。呜呼！我的机械相机！自从法国人达盖尔发明了银盐版的照相术，自然而然也就出现了“摄影”这一概念。与其说是一个新概念，不如说是一种新事物。是新事物，人们也就不免会生出许多议论。有人把它当作记录历史的工具，有人把它…

“海鸥”──中国民族工业的骄傲

上海海鸥照相机厂（前身为上海照相机总厂）迄今走过了整整38个春秋，38年的历史雄辩地证明：“海鸥”，作为中国照相机第一品牌，当之无愧！过硬的质量是名牌的第一要素。早在70年代，美国近代投影杂志就对中国照相叽作了如下报道：海鸥DF照相机镜头好，与德国名牌蔡司厂勃奥它性能相似，镜头座圈保证了镜头对胶片垂直性，对光学成像有良好的效果；快门释放揿钮轻，润滑及正确不亚于美能达。80年代初，海鸥4型相机曾多次被评为国内120型相机质量第一；海鸥DF－1单镜头反光相机质量获全国省市级荣誉更是不胜枚举。90年代初，意大利一家摄…     

金箔面临挑战

金箔历史悠久 在中国，金箔的历史非常悠久。根据考古发现，距今3300多年的我国商代河南安阳殷墟以及河北藁城商代中期遗址都有金箔出土，上世纪80年代在三星堆考古发掘中也发现了商代的金箔，其中殷墟出土的金箔厚度仅0．01毫米左右。中国金箔起源于南京，而南京金箔起源于龙潭。龙潭的老人们都称，过去打金箔的人家都供着葛仙翁像。从民间传说和民间供奉推算，金箔的大量出现应在六朝时期，而现在无论是福建漳州还是江苏苏州，金箔业都奉葛仙翁为行业始祖。可见，南京龙潭是金箔制造源头说并非虚言，     

近视的美国人

初到美国，原以为语言是工作生活的最大障碍。可是一接触实际，马上发现：度量衡用法的沟通比语言更困难。因为作为世界科技强国的美国——至今仍保持着古老繁琐的英制“度量衡”制度，而报载英国也将使用公制“度量衡”制，从而将结束近700年历史的英制单位。作为一名中国工程师，我通过职业介绍所，很快进入纽约一家建筑公司。第一天工作，是绘制一张商场平面图。我按中国规范，用公制单位，按惯用的比例1：100，不到2小时就绘制完毕。可是拿给老板一看，他连连摇头：No！No！No！……。原来他看不懂公制的尺寸，比例也不同。美国人惯用…     

爆炸法密实砂土地基(Ⅰ)——研究现状

Association between initial type of hemodialysis access used in the elderly and mortality

We hypothesized that certain subpopulations (elderly and those with greater comorbidity) may not have significant benefit from "fistula first" initiative. A cohort of incident hemodialysis patients from 2005 to 2007, who were ≥70 years old, was derived from the United States Renal Data System. Primary variable of interest was type of vascular access used at first outpatient hemodialysis (i.e., fistula, graft, or central catheter), with primary outcome of all-cause mortality (time to death measured from the first outpatient hemodialysis). A cohort of 82,202 patients was stratified by age (70 to ≤80, 81 to ≤90, and >90). Each group demonstrated a survival benefit with the use of an arterio-venous fistula compared with catheter (hazard ratio [HR] 0.56 [P < 0.001], HR 0.55 [P < 0.001], and HR 0.69 [P = 0.007], respectively). Comparing graft to with a catheter, both groups, 70 to ≤80 and 81 to ≤90, had significant benefit compared with catheter (HR 0.73, P < 0.001 and HR 0.74, P < 0.001, respectively). However, significance was lost in those ≥90 (HR 0.83, P = 0.354). When substratified by comorbidity, those 81 to ≤90 years old with a history of malignancy or peripheral vascular disease also did not reach significant benefit compared with a catheter (HR 0.88, P = 0.423 and HR 0.85, P = 0.221, respectively). While specific subgroups in the hemodialysis population exist where use of fistulas and grafts at time of dialysis initiation is not of proven statistical benefit to survival, elderly hemodialysis patients with comorbidities still appear to benefit from the use of fistulas and grafts.

Dynamic Experimental Study of Deployable Composite Structure

In this paper, dynamic behaviors of deployable composite structure are experimentally studied. Firstly, both the composite tape springs and the deployable composite structure are fabricated using the carbon/epoxy and glass/epoxy composite thin cylindrical shells, respectively. Secondly, the deployable behaviors of thin cylindrical shell specimens with section angle θ = 70° and 90° are investigated based on the strain history in three directions (0o, 45oand 90o). Finally, the deployment behaviors of the deployable carbon/epoxy composite structure with two hinges and three hinges are also studied including the deployment process and dynamic strain history.     

Impact of mandating a driving lesson for older drivers at license renewal in Japan

In Japan, a driving lesson consisting of a lecture, a driver aptitude test, on-road driving assessment and a discussion session was added to the driving license renewal procedure for drivers aged 75 years or older in 1998 and for drivers aged 70 years or older in 2002. We investigated whether these additions contributed to a reduction in at-fault motor vehicle collisions (MVCs) by examining the trend of the at-fault MVC rates per licensed driver and the rate ratios of the older drivers relative to those aged 65–69 years for the years 1986–2011. All data were derived from nationwide traffic statistics. If the introduction of the lesson was effective in reducing at-fault MVCs of older drivers, the rate ratio should have declined, given that the lesson targeted only the older drivers. We found this was not the case, i.e., there was no declining trend in the at-fault MVC rate ratios of both drivers aged 75 years or older and drivers aged 70 years or older, relative to drivers aged 65–69 years, after the driving lesson at license renewal became mandatory for these older drivers. Therefore, the mandatory lesson for the older drivers at license renewal needs to be reconsidered.

Determining the validity of the AMA guide: A historical cohort analysis of the Assessment of Driving Related Skills and crash rate among older drivers

Background

Chronic health conditions associated with ageing can lead to changes in driving ability. The Canadian Driving Research Initiative for Vehicular Safety in the Elderly (Candrive II) is a 5-year prospective study funded by the Canadian Institutes of Health Research aiming to develop an in-office screening tool that will help clinicians identify potentially at-risk older drivers. Currently, no tools exist to directly predict the risk of motor vehicle collision (MVC) in this population. The American Medical Association (AMA), in collaboration with the National Highway Traffic Safety Association, has designed an opinion-based guide for assessing medical fitness to drive in older adults and recommends that physicians use the Assessment of Driving Related Skills (ADReS) as a test battery to measure vision, cognition and motor/somatosensory functions related to driving. The ADReS consists of the Snellen visual acuity test, visual fields by confrontation test, Trail Making Test part B, clock drawing test, Rapid Pace Walk, and manual tests of range of motion and motor strength. We used baseline data from the Candrive/Ozcandrive common cohort of older drivers to evaluate the validity of the ADReS subtests. We hypothesized that participants who crashed in the 2 years before the baseline assessment would have poorer scores on the ADReS subtests than participants who had not crashed.

Methods

In the Candrive/Ozcandrive study, 1230 participants aged 70 years or older were recruited from 7 Canadian cities, 1 Australian city and 1 New Zealand city, all of whom completed a comprehensive clinical assessment at study entry. The assessment included all tests selected as part of the ADReS. For this historical cohort study, data on all crashes (at-fault and non-at-fault) that occurred within 2 years preceding the baseline assessment were obtained from the respective licensing jurisdictions. Those who crashed were compared to those who had not crashed on their ADReS subtest scores using Pearson's chi-squared test and Student's t-test.

Results

Sixty-three of the 1230 participants (5.1%) were involved in an MVC within the 2 years preceding the baseline assessment. Contrary to our hypothesis, there were no statistically significant associations between abnormal performance on the tests constituting the ADReS and history of crash in the previous 2 years (p > 0.01).

Discussion

We found that a history of crash in the previous 2 years was not associated with abnormalities on the subtests comprising the ADReS. This suggests the need for prospective analyses of risk factors over time to establish sensitive, valid predictors of crash that can be incorporated in clinical practice guidelines.     

氯离子侵蚀下RC框架结构时变抗震性能研究

氯离子侵蚀作用引发的结构耐久性损伤将导致RC结构抗震性能发生时变劣化。在材料层次,该文通过考虑钢筋截面削弱、保护层混凝土开裂软化、核心区混凝土极限压应变降低等模拟氯离子侵蚀对RC框架结构材料性能的影响,并基于试验数据验证了模拟方法的准确性;在结构层次,基于上述材料力学性能退化模型和纤维模型,对3层、6层与8层多不同服役期(0年、30年、50年和70年)RC框架结构进行数值建模,继而进行了静力与动力弹塑性分析,研究了其随服役期增长承载与变形能力退化规律和层间位移角分布变化规律。研究结果表明:结构腐蚀后,随着服役期的增加,结构承载力、特征点位移、位移延性、软化段刚度等抗震性能指标均逐渐减小,结构的屈服PGA和倒塌PGA亦不断降低,结构最大层间位移角不断增大,且结构在罕遇地震作用下层间位移反应受服役期影响较设防地震作用更为明显。     

Fullerenes in the Fossil of Dinosaur Egg

By means of laser desorption post-ionization time-of flight mass specrometry (TOF) and high-pressure liquid chromatography (HPLC), fullerene C₆₀ have been found in a fossil of dinosaur egg shell from Xixia (N_33.3 E_111.4), China. These techniques verified also mat fullerene C₇₀ is virtually absent from identical egg fossil of dinosaur at XiXia. Preliminary results suggest that C₆₀ occurrence and C₇₀ absence may be the outcome of environment (ambient temperature, and SO₂ pollution of Earth's atmosphere, etc.) effects during the synthesis of fullerenes at 70 million years ago.
