关键词： 背书   栏杆   阳台  

摘要： 爷爷奶奶睡了,整个镇子上的人都睡了,这会儿出来活动的就只有老鼠了。小老鼠起初还有所忌惮,在栏杆的拐角处探头探脑,不敢出来,默默地在那儿守着,大概是等我离开。最后,它终于等得不耐烦了,大摇大摆地走上阳台,吱吱吱,吱吱吱,比我背书还起劲呢,似乎在嘲笑我。

摘要： Purpose/Objective(s) The outcomes of second primary head and neck malignancies in survivors of HPV associated OPSCC treated with radiation have not been well documented. The purpose of this study was to review the rate, management, and outcomes of non-metastatic second head and neck malignancies in patients with a history of HPV positive OPSCC treated with definitive or postoperative radiation (RT). Materials/Methods This is a single institution IRB approved retrospective study of patients with HPV positive OPSCC treated from 2001-2017 with definitive radiation and at least 3 years of follow up. Diagnoses were considered to be a second head and neck malignancy if they were distinct from index OPSCC with the exclusion of a primary or regional recurrence, primary site > 2 cm from the index OPSCC, and occurred at least 2 years from prior RT. Patients with second malignancies involving the thyroid were excluded. Actuarial analysis was used to calculate overall survival and disease control rates. Results There were a total of 418 patients who met inclusion criteria with a median follow up of 88.5 months (50.9-150.9 months). A total of 11 patients (2.6%) developed a second primary malignancy in the head and neck (2 larynx, 1 nasal cavity , 6 oral cavity and 2 oropharynx) and all were treated with definitive surgery. Median time between first and second cancers was 73 months (25-123 months). Median follow up for these patients was 25.4 months (7.7-69 months) and the median age at second malignancy was 65 years (range 54-73 years). 64% of patients were former smokers (quit > 3 months) and 36% were never smokers. Pathological tumor stage of the second cancer was T1 in 36%, T2 in 27%, T4a in 36%. The histology was squamous cell carcinoma in 9 patients, spindle cell squamous carcinoma in 1 patient, and adenosquamous carcinoma 1 patient. HPV status was negative in 45.5%, positive in 18.2% and unknown in 36.4%. Post-operative re-irradiation was given in 55%, of which 50% receive

关键词： 轻集料混凝土隔墙条板   U形钢卡件   安装   裂缝  

摘要： 由于胶凝材料本身具有的干缩、徐变作用,以及在使用过程中的温度、湿度变化,轻集料混凝土隔墙条板自身容易产生细微裂缝。通过对板材拼缝的形状设计,由平头缝调整为曲柄型断面,有目的地将单块板上的变形引导至板材拼缝处,有效降低了墙板后期出现裂缝的可能性。另外,在施工过程中,通过加强对细部关键节点的质量控制,轻集料混凝土隔墙条板裂缝问题得到了有效控制,为后续类似工程提供了参考。

摘要： Purpose/Objective(s) While prospective trials have established stereotactic body radiation therapy (SBRT) as standard of care for inoperable early-stage non-small cell lung cancer (NSCLC), these studies excluded patients with tumors larger than 5 cm. Since these patients have few treatment options and conservative management is associated with significant morbidity, many clinicians utilize SBRT if dosimetric constraints can be met. The purpose of this study is to determine the rate of primary tumor failure (PTF) after SBRT for NSCLC with primaries ≥ 5cm. Materials/Methods We performed a retrospective review of all patients with NSCLC and large primary tumors (≥ 5 cm in maximum dimension) treated at our institution using SBRT from 2010 – 2018. Patients with nodal or distant disease were included, but only evaluated for toxicity and PTF. Treatment failures were captured by review of imaging, pathology, and clinical notes. PTF was defined as disease recurrence in or at the margin of the primary tumor volume (PTV) and was measured from end of SBRT to PTF. Patients without PTF were censored at last follow up or death. The Kaplan-Meier method was used to estimate event-time probabilities for PTF. Predictors of PTF were analyzed using log rank tests between groups and a parsimonious multivariate Cox multivariate model. Results A total of 145 patients were identified. Median age was 78 years (Interquartile rage [IQR] 72 -84). Evidence of regional disease was present in 5 (3%) patients and metastatic disease in 14 (10%). Median tumor diameter was 5.75 cm (IQR 5.25 – 6.43) and tumor volume was 37.9 cm 3 (IQR 25.4 – 53.6). The most common SBRT regimen was 48 Gy in 4 fractions (68 patients). Median BED10 was 105.6 (IQR 105.6-151.2). With a median follow up of 21 months (IQR 9 – 32), PTF at 1, 2, and 3 years was 10.6% (95% Confidence Interval [CI] 5.1 – 16.1), 17.0% (95% CI 9.9 – 24.1), and 22.0% (95% CI 13.4 – 30.6). On univariate analysis , factors associated with PTF included

关键词： 体型系数   水平构件   《高规》   荷载规范   雨篷   遮阳板   工程事故   双坡  

摘要： 1问题引入JGJ 3—2010《高层建筑混凝土结构技术规程》(简称《高规》)第4.2.8条规定,“檐口、雨篷、遮阳板、阳台等水平构件,计算局部上浮风荷载时,风荷载体型系数不宜小于2.0。”有了《高规》这条规定,雨篷的负风压体型系数μs取值为-2.0是没有争议的。但《高规》没有规定雨篷向下的正风压荷载体型系数如何取值,所以争议较大。很多人觉得不用考虑正风压,原因很简单,从已发生的工程事故来看,基本都是雨篷被吹翻,很少听过被吹掉,也有人认为可参考GB 50009—2012《建筑结构荷载规范》(简称《荷载规范》)表8.3.1第29项“单坡及双坡顶盖”的体型系数来取值,但也觉得与雨篷形式不太一样。对于向下荷载工况控制时,正风压的不利作用是不能忽略的,大雪时将雨篷压塌的事故,谁敢说没有正风压的作用呢?只是《荷载规范》没有规定,每个人的想法肯定不一样,所以执行起来很困难。
