Migrating from traditional grid to smart grid in smart cities promoted in developing country
No full textSmart Grid is a term that encompasses the economic benefits of an intelligent and advanced power grid to reach
changing responsibilities related directly to sustainability and energy efficiency. Considering the shortfall of
alternative fuels in developed regions, the new smart grids, in order to have access to their environmental hazard,
show that the average non-renewable and renewable energy sources can be integrated to reduce environmental
disasters to improve production costs significantly. In order to provide reliable, secured, and cost-effective power
grid functions, infrastructures can quickly and effectively co-ordinate power-sharing between several renewable
energy sources freely accessible and economically demand costs. This article reviews the conceptual model,
goals, architecture, potential benefits, and power grid issues with a complete and accurate understanding of the
different defenders and people involved in the worldwide region scenario. The article examined energy and
transmission issues, including smart grids and grid barriers, comprehensively

Patients and methods Our study included 66 patients with bipolar I disorder and 64 controls aged 37.9 ± 12.6 and 36.3 ± 18.2 years, respectively. Paraoxonase activity was determined by kinetic methods; high-density lipoprotein cholesterol (c-HDL), low-density lipoprotein cholesterol (c-LDL), triglycerides and total cholesterol were determined by enzymatic methods; apolipoprotein (Apo)A1, ApoB and lipoprotein (a) (Lp(a)) were determined by immunoturbidimetry using Konelab 30 equipment (Thermo Scientific). Results Compared with controls, patients had a significantly lower paraoxonase activity and ApoA1 level, and significantly higher total cholesterol, c-LDL and Lp(a) level and ApoB/ApoA1 ratio. Furthermore, paraoxonase activity was significantly correlated with c-HDL values (r = 0.5612; P Conclusions Bipolar patients had a significant decrease in paraoxonase activity and perturbations in their lipid profile that contribute to increased risk of cardiovascular diseases. Decrease in this activity was significantly associated with treatment with lithium but not with sociodemographic and clinical characteristics. Therefore, such patients require specific care, particularly with regard to their lipid profile.</p
