One of the most critical issues in the evaluation of power systems is the identification of critical buses. For this purpose, this paper proposes a new methodology that evaluates the substitution of the power flow technique by the geodesic vulnerability index to identify critical nodes in power *** methods are applied comparatively to demonstrate the scope of the proposed approach. The applicability of the methodology is illustrated using the IEEE 118-bus test system as a case study. To identify the critical components, a node is initially disconnected, and the performance of the resulting topology is evaluated in the face of simulations for multiple cascading faults. Cascading events are simulated by randomly removing assets on a system that continually changes its structure with the elimination of each component. Thus, the classification of the critical nodes is determined by evaluating the resulting performance of 118 different topologies and calculating the damaged area for each of the disintegration curves of cascading failures. In summary, the feasibility and suitability of complex network theory are justified to identify critical nodes in power systems.

Diabetic ketoacidosis remains one of the most serious complications of diabetes mellitus. Among its precipitating factors is myocardial ischemia, responsible for 1% of the cases of diabetic *** Diabetic ketoacidosis both with and without hyperkalemia has been reported to mimic a myocardial infarction pattem on ECG with ST segment elevation, described as pseudoinfarction pattern. Thus, it is important to raise awareness among physicians, as subjecting patients to invasive medical management can be avoided. We present a case of a 47-year-old female with diabetic ketoacidosis and hyperkalemia with initial ECG findings of ST segment elevation, but an urgent left heart catheterization revealed non-obstructive coronary disease.

Operation conditions to recover and quantify active compounds from Perle Hallertau (PH) and Nuggets (N) hops, following a sequential combination of ultrasound and microwave assisted ethanolic extraction were studied. Ultrasound treatment (55 °C, 60% ethanol, 30 minutes) allowed extracts with phenolic contents of 160.43 mg GAE/g extract and ABTS radical scavenging capacity equivalent to 400.24 mg Trolox/g extract for PH. Optimal conditions for N were found at 55 °C, using 60% ethanol for 120 minutes (98.80 mg GAE/g extract) and 55 °C, 40% ethanol for 180 min (370.00 mg Trolox/g extract). The remaining solids were further processed under ethanolic microwave extraction (130–190 °C, 5 minutes) with the optimal results obtained at 190 °C for PH (77.11 and 98.67 mg GAE/g extract) and N (226.96 and 368.72 mg Trolox/g extract). Results obtained provided hops pellets as a rich source of active compounds that could be suitable for food and no food industry applications.
