The use of intelligent nanocomposites in sensing and actuation applications has become quite common over the past decade. In this article, electro-thermo-mechanical nonlinear dynamic buckling of an orthotropic piezoelectric nanocomposite (PNC) cylindrical shell conveying viscous fluid is investigated. The composite cylindrical shell is made from Polyvinylidene Fluoride (PVDF) and reinforced by ...

The effect of central opening on the buckling and nonlinear post-buckling response of carbon nanotubes (CNTs) reinforced micro composite plate embedded in elastic medium is considered in this paper. It is assumed that the system is surrounded by elastic medium, therefore; the influence of Pasternak foundation on buckling and post-buckling behavior are analyzed. In order to derive the basic form...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

This work combines a theoretical study of electrical interactions between two excitable heart cells, using a variable coupling resistance, with experimental studies on isolated rabbit ventricular cells coupled with a variable coupling resistance to a passive resistance and capacitance circuit. The theoretical results show that the response of an isolated cell to an increased frequency of stimul...

INTRODUCTION Postoperative infections are a major complication associated with tissue-expander-based breast reconstruction. The use of acellular dermal matrix (ADM) in this surgery has been identified as a potential reservoir of infection, prompting the development of sterile ADM. Although aseptic and sterile ADMs have been investigated, no study has focused on the occurrence and clinical outco...

OBJECTIVE Evaluate the influence of the glycemic index (GI) and glycemic load (GL) of the diet in the glycemic control of children and teenagers with type 1 diabetes mellitus (DM1). METHODS A total of 146 subjects, aged 7-19 years, monitored at the Division of Pediatric Endocrinology at the HC/UFMG participated in the study. The consumed diet was evaluated using a quantitative food frequency ...

Exploitation of modern power systems requires prediction of the electrical load time series for operation of power utilities and load estimates for market operation and system planning. Increase of energy produced from renewable sources and deregulation of electrical energy market makes load prediction more important nowadays. By its nature, electrical load time series are highly non linear and...

In order to evaluate the mechanical condition and working performance of a rigid frame bridge after reconstruction extension, was analyzed by static load test. Static test is stress at each section main beam under action partial medium load. The results show that, load, check coefficient strain deflection measuring point box girder does not exceed standard limit value 1, relative residual or de...
