BACKGROUND ambulatory blood pressure (ABPM) appears to be a more accurate predictor of cardiovascular outcome than blood pressure (BP) measured in the clinic setting in younger adults. OBJECTIVES the purpose of this study was to determine if ABPM predicted total and cardiovascular mortality independently of clinic BP and other cardiovascular risk factors in those aged 65 years and over. MET...

Background & Aims of the Study: The present research aims to use sediment quality indices in the assessment of toxicity and ecological risk factors of heavy metals Pb, Cu and Zn in Anzali, Meighan, Shadegan and Hashilan wetlands. Material & Methods: Given the environmental conditions, surface sediments in 71 diverse stations were sampled in three replications. Having preparation and subject...

The present study evaluates health risk assessment for inhabitants who are exposed to chromium in fishes and vegetables of the Gulshan Lake. In the fish, chromium concentration has amounted to 2.2 to 149.7 mg/kg, while in vegetables leaf and vegetables stem it has been 5.6 mg/kg and 12.0 mg/kg, respectively. What is more, in sediment it has been 179.5 to 308 mg/kg and in water, 4.0 to 16.9 mg/l...

the percent of normal precipitation index (pnpi) is a widely used drought index to provide good estimations about the intensity, magnitude and spatial extent of droughts. the objective of this study was analyzing spatial pattern of drought by pnpi index. in this paper, according to the data of 40 stations in iran, during 1967-2009, the pattern of drought hazard is evaluated. influenced zone of ...

the identification of natural hazard prone areas for future planning requires an efficient decision support tool to provide the appropriate weights for the various topographical, geological, and seismological factors responsible for the expected hazards. in the present study, an analytical hierarchy process (ahp) with six earthquake hazard parameters (ehps) was used as a decision support system...

Climate change has made The Gambia vulnerable to drought hazard. Variability and negative trends in rainfall quantity mid-season dry spells mainly attributed the impacts of climate change. inadequacy hydrometeorological information puts agricultural sector at a high risk which employs over 70% population. aim this study was establish intensity spatiotemporal pattern from 2000 2020 using multipl...

cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...

Abstract The study presents a time-dependent analysis of threats from man-made climate change at 244 UNESCO cultural and natural heritage sites in the Mediterranean. hazards our research are estimated by indices based on extremes heat, fire weather conditions, heavy rainfall days, frost changes mean sea level aridity each site. These were calculated regional EUROCORDEX simulations, cover period...

background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...

Abstract. Drought is understood as both a lack of water (i.e., deficit compared to demand) and temporal anomaly in one or more components the hydrological cycle. Most drought indices, however, only consider aspect, i.e., how unusual condition is. In this paper, we present two hazard indices that reflect aspects. The soil moisture index, SMDAI, based on severity DSI (Cammalleri et al., 2016), bu...
