Obesity is a public health problem contributing to morbidity and mortality from metabolic syndrome. It has long been recognized that there is a gender dependency in several obesity-related health risks. Using a high fat diet (HFD) to induce obesity in Wistar rats, we studied the gender dependency of fat-induced oxidative stress in the heart and liver, with a special emphasis on the distribution of transition metals, as well as the protective effects of grape seed and skin extract (GSSE). HFD induced ...

It is unknown whether gender has an impact on brain injury in obesity, and, if so, whether treatment with grape seed and skin flour could exert a protective effect. Both male and female rats were fed a standard diet (SD) or a high fat diet (HFD) during eight weeks and treated with high dosage grape seed and skin flour (GSSF). Fat-induced oxidative stress was evaluated into the brain with a special emphasis on transition metals determination. HFD induced male-cholesterol overload (+78.12%) and an oxidative ...

In this paper, an experimental study and modeling by artificial neural networks were carried out to predict the generated microdroplet dimensionless size in a microfluidic system in order to formulate a water-in-oil emulsion. The various parameters that affect the size of microdroplets (flow rates, viscosities, surface tensions of both the two phases and the diameter of the microchannel) are studied and further grouped into dimensionless numbers; we used these numbers as input to the neural network ...

Generating micrometer sized droplets has been studied in a microfluidic system with T-junction geometry 250 μm in internal diameter and with PTFE capillary tubing. Several experiments were conducted by varying the flow rate of the dispersed phase from 2.78⋅10−11 m3/s to 5.28⋅10−9 m3/s and that of the continuous phase from 2.78⋅10−10 m3/s to 1.94⋅10−9 m3/s. The visualization of different flow regimes (drop, plug, and annular) was carried out for three configurations (not inverted in a horizontal position, ...

The intelligent buildings provided various incentives to get highly inefficient energy-saving caused by the non-stationary building environments. In the presence of such dynamic excitation with higher levels of nonlinearity and coupling effect of temperature and humidity, the HVAC system transitions from underdamped to overdamped indoor conditions. This led to the promotion of highly inefficient energy use and fluctuating indoor thermal comfort. To address these concerns, this study develops a novel ...

In this study, a new adaptive controller based on modified feedback error learning (FEL) approaches is proposed for load frequency control (LFC) problem. The FEL strategy consists of intelligent and conventional controllers in feedforward and feedback paths, respectively. In this strategy, a conventional feedback controller (CFC), i.e. proportional, integral and derivative (PID) controller, is essential to guarantee global asymptotic stability of the overall system; and an intelligent feedforward controller ( ...

Obesity is a public health problem and a major risk factor for metabolic syndrome. This study was designed to assess the effectiveness of grape seed and skin extract (GSSE) and Xenical (Xe) on high fat diet (HFD)-induced obesity and brain lipotoxicity.Rats were rendered obese and then treated either with vehicle (control) or GSSE (4g/kg bw) or Xe (1, 2, 4 or 8mg/kg bw) or (GSSE+Xe) and monitored for weight loss during 3 months. Animals were then sacrificed and their brain utilised for the evaluation of ...

In wireless sensor networks (WSNs), location or distance estimation information for the elderly is a critical issue. This study aims to improve the error in estimated distance between the anchor node and mobile node, which is carried by an elderly person while moving in an indoor environment. The distance between the mobile node and the anchor node was determined based on the measured received signal strength indicator (RSSI) of the anchor nodes and the artificial neural network (ANN). The ANN was ...

Spleen is the largest lymphoid organ and obesity is related to an elevated risk of immunity dysfunction. The mechanism whereby fat adversely affects the spleen is poorly understood. This study was designed to assess the effectiveness of grape seed and skin extract (GSSE) and orlistat (Xenical, Xe) on high-fat diet (HFD)-induced spleen lipotoxicity. Obese rats were treated either with GSSE (4 g/kg body weight) or Xe (2 mg/kg body weight) or GSSE+Xe and monitored for weight loss for 3 months. Animals were ...

In the design of reinforced concrete (RC) bridges, the random and nonlinear behavior of soil may lead to insufficient reliability levels. For this reason, it is necessary to take into account the variability of soil properties which can significantly affect the bridge behavior regarding ultimate and serviceability limit states. This study investigates the failure probability for existing reinforced concrete bridges due to the effects of interaction between the soil and the structure. In this paper, ...

Photocatalytic degradation of direct red 264 under visible light using NiFe 2 O 4 and Zn‐doped NiFe 2 O 4 nanoparticles was the primary goal of this work. Hence, NiFe 2 O 4 and Zn‐doped NiFe 2 O 4 nanoparticles were prepared by the sol–gel auto combustion method. The powder X‐ray diffraction pattern unveiled the formation of spinel phase of NiFe 2 O 4 with the average crystallite size determined from the Scherrer equation. The FTIR spectra of the samples revealed the vibration bands of Fe–O and ...

Abstract Nowadays this concept has been widely assessed due to its complexity and sensitivity for the beneficiaries, including passengers, airlines, regulatory agencies, and other organizations. To date, various methods (e.g., statistical and fuzzy techniques) and data mining algorithms (e.g., neural network) have been used to solve the issues of air traffic management (ATM) and delay the minimization problems. However, each of these techniques has some disadvantages, such as overlooking the data, ...
