The impact of climate change on water and energy security

Abstract The interdependent fundamental systems, water and energy, face abundant challenges, one of which is climate change, which is expected to aggravate water and energy securities. The hydropower industry's benefits have led to its development and growth around the world. Nonetheless, climate change is expected to disturb the future performance of hydropower plants. This study looks at the Seimareh Hydropower Plant to assess the potential vulnerability of hydropower plants to climate change. Results indicate that climate change will affect the area's hydrological variables and suggest an increase in temperatures and decrease in precipitation during a 30-year future period (2040–2069). It is predicted that Seimareh Dam's inflow will decrease by between 5.2% and 13.4% in the same period. These hydrological changes will affect the Seimareh plant's performance: current predictions are that the total energy produced will decrease by between 8.4% and 16.3%. This research indicates the necessity of considering climate change impacts in designing and maintaining hydraulic structures to reach their optimal performance

Comparison of prevalence of metabolic syndrome between idiopathic and secondary deep vein thrombosis

Background- The association of the metabolic syndrome with idiopathic or secondary deep vein thrombosis (DVT) remains uncertain. In addition, the relevance of the different features of the metabolic syndrome as an independent or pivotal risk factor for DVT is controversial. We aimed to evaluate the prevalence of the metabolic syndrome in patients with idiopathic or secondary DVT and also compare the prevalence of the different components of this syndrome in the two clinical etiological conditions of DVT. Methods- In a cross-sectional study, 115 consecutive patients with a recent objective diagnosis of DVT (idiopathic in 87 patients and secondary to a known risk factor in 28 patients) who were referred to Rajaei Heart Center between April 2009 and January 2010 were enrolled in the study. In all the patients, DVT was diagnosed by means of compression Doppler ultrasonography. The metabolic syndrome was defined according to the ATP III recommendations. Results- Overall prevalence of the metabolic syndrome in the study participants was 9.6, and the prevalence of the metabolic syndrome in patients with idiopathic or secondary DVT was 9.2 and 10.7, respectively, which was not different between them. Relative to the presence of the different numbers of the metabolic syndrome features, no difference was found between the groups with idiopathic or secondary DVT. The presence of no feature was found in 6.9 and 7.1, the presence of one feature was seen in 51.7 and 42.9, and the presence of two features was found in 32.2 and 39.3, respectively. Conclusion- Regardless of the etiology of DVT, the overall prevalence of the metabolic syndrome in our DVT subjects ranged from 9.2 to 10.7, and this prevalence was independent of the etiology (idiopathic or secondary) of DVT
