BACKGROUND Hypertension is a common public health problem worldwide and is a well-known risk factor for increased risk of cardiovascular diseases,contributing to high morbidity and ***,there has been no systematic review and meta-analysis of a multiethnic population such as that of *** To determine the trend in prevalence,awareness and control rate of hypertension in *** Systematic searches were conducted in six databases(PubMed,Scopus,Ovid,CINAHL,Malaysian Medical Repository and Malaysia Citation Index)for articles published between 1980 and *** authors reviewed the studies and performed quality assessment and data extraction *** estimates of hypertension prevalence,awareness and control rate were calculated using the DerSimonian-Laird random-effects *** and sensitivity analyses were *** We included 56 studies involving a total of 241796 *** overall pooled prevalence of hypertension aged≥18 years was 29.7%.The prevalence of hypertension was the lowest in the 1980s(16.2%,95%confidence interval(CI):13.4,19.0),increasing up to 36.8%(95%CI:6.1,67.5)in the 1990s,then decreasing to 28.7%(95%CI:21.7,35.8)in the 2000s and 26.8%(95%CI:21.3,32.3)in the *** prevalence of awareness was 51.4%(95%CI:46.6,56.3),while 33.3%(95%CI:28.4,38.2)of those on treatment had achieved control of their blood *** In Malaysia,three in ten adults aged≥18 years have hypertension,while four in ten adults aged≥30 years have *** out of ten people are aware of their hypertension status and only one-third of those under treatment achieved control of their *** efforts by policymakers and healthcare professionals to improve awareness and control of hypertension should be of high priority.

Strengthening of Concrete Box Girder Bridges under Close-in Detonations

引用

Journal of Civil Engineering and Architecture 2012年第6期6卷 699-706页

作者： Ahmed Ibrahim hani salim Department of Civil Engineering and Construction Bradley University Peoria IL 61625 USA Department of Civil and Environmental Engineering University of Missouri Columbia MO 65211 USA

The response of a bridge superstructure under blast loading might depend largely on the extent of the local damage experienced due to close-in explosion threats. This paper investigates the local and structural response of box girder bridge decks strengthened using CFRP （carbon fiber reinforced polymers） under close-in detonations. Due to the lack of experimental research on this topic, the study is conducted using the explicit finite element computer program LS-DY-NA. The numerical study will be verified using the results of strengthened reinforced concrete slabs under field detonations. The blast load was assumed to be detonated above the bridge deck. The key parameters investigated are the charge size, and the strengthening location on the deck. This paper will present the results of this investigation and provides recommendations for predicting the local damage level based on the CFRP strengthening design under blast threat.
