13. Interleukin-6 contributes to myocardial damage in pregnant rats with reduced uterine perfusion pressure
Preeclampsia is one of the most frequent and difficult illnesses in pregnancy, which jeopardizes both mother and fetus. There are several diagnostic criteria for preeclampsia. However, the preeclampsia-associated myocardial damage has not been described. In this study, we employed reduced uterine perfusion pressure (RUPP) to generate a rat model of preeclamp

14. Antioxidant extract counteracts the effects of aging on cortical spreading depression and oxidative stress in the brain cortex
Abstract Purpose: To investigate the effects of Murici extract on the brain excitability-dependent phenomenon known as cortical spreading depression (CSD) and on brain oxidative stress. Methods: Adult and aged Wistar rats were supplemented with murici extract (150 mg/kg/day or 300 mg/kg/day) by gavage for fifteen days. Afterwards, the animals were submitt

15. Exploring the effects of deep-defending vs high-press on footballers’ tactical behaviour, physical and physiological performance: A pilot study
Abstract AIMS The aim of this study was to explore the effects of a deep-defending vs high-press defending strategy on footballers’ tactical behaviour, physical and physiological responses, when in numerical difference. METHODS Nineteen elite professional footballers (outfield players) participated in this study, playing an 11vs10 match (simulating an ea

16. Proper Orthogonal Decomposition and Spectral Analysis of a Wall-Mounted Square Cylinder Wake
ABSTRACT: The flow patterns over a finite square cylinder of aspect ratio of 3 were analyzed experimentally in a subsonic wind tunnel using the time-resolved particle image velocimetry (TR - PIV) techniques. The near wake flow structures and vortex shedding characteristics were investigated using mean flow analysis, spectral analysis and proper orthogonal de

17. Parametric study of sweetening process of sour gas by Molybdenum oxide nanoparticles
Abstract The purpose of this work is to study the application of nano-molybdenum oxide adsorbent in gas sweetening process. Experiments were made to evaluate the operating and geometrical parameters in the adsorption process. The process performance of H2S removal from methane gas on molybdenum oxide nanoparticles was defined as the ratio of final concentrat

18. Numerical Analysis of Swirl Effects on Conical Diffuser Flows
ABSTRACT: The present paper focuses on the effect of swirl on important parameters of conical diffusers flows such as static pressure evolution, recirculation zones and wall shear stress. Governing equations are solved using a software based on the finite volume method. Moreover, turbulence effects are taken into account employing the k-ε RNG model with an

19. Vasculopathy associated with peripheral neuropathy in gait parameters of diabetic people
Abstract Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus when glycemic levels are poorly controlled. Sometimes DPN is accompanied by vasculopathy (DPV), which can worsen the clinical prognosis. The aim of this study was to analyze the gait parameters of nondiabetic individuals and diabetic individuals with DPN with or witho

20. Wind Tunnel Testing on a Generic Model of a Hybrid Lifting Hull
ABSTRACT In this research, an experimental investigation was carried out at the International Islamic University Malaysia - Low Speed Wind Tunnel facility on a generic model of a hybrid lifting hull. Based on the historical trends of non-rigid airships, the fineness ratio of the said hull has been selected equal to 4. Free stream velocity was kept at 20 m/s

21. Statins for aortic valve stenosis
ABSTRACT BACKGROUND: Aortic valve stenosis is the most common type of valvular heart disease in the USA and Europe. Aortic valve stenosis is considered similar to atherosclerotic disease. Some studies have evaluated statins for aortic valve stenosis. OBJECTIVES: To evaluate the effectiveness and safety of statins in aortic valve stenosis. METHODS: Searc

22. Optimizing the Water-Oil Emulsification Process for Developing CPC Microspheres
Spherical calcium phosphate cement carriers were synthesized by water/oil emulsion. A 23 factorial design was employed in order to optimize the size and form of the microspheres. Stirring speed, liquid-to-powder ratio and cement paste-to-oil ratio were varied in two different levels and the response variable was the microsphere's sphericity. The results show

23. Analysis of combustion efficiency in a pelletizing furnace
Abstract The objective of this research is to assess how much the improvement in the combustion reaction efficiency can reduce fuel consumption, maintaining the same thermal energy rate provided by the reaction in a pelletizing furnace. The furnace for pelletizing iron ore is a complex thermal machine, in terms of energy balance. It contains recirculation fa

24. DOLOMITE DESULFURIZATION BEHAVIOR IN A BUBBLING FLUIDIZED BED PILOT PLANT FOR HIGH ASH COAL
Abstract Although fluidized bed in situ desulphurization from coal combustion has been widely studied, there are aspects that remain under investigation. Additionally, few publications address Brazilian coal desulphurization via fluidized beds. This study used a 250 kWth bubbling fluidized bed pilot plant to analyze different aspects of the dolomite desulphu
