Nano silica particles are obtained from the inexpensive agricultural waste rice husk ash, by acid alkali treatment. Organic and chemical modifications are done in the nano silica particles in order to enhance their surface reactivity and to introduce reactive functional groups to achieve adequate bonding…

The method of low-frequency impedance spectroscopy has been successfully applied in Earth sciences to characterize soils and rocks. The method uses the diagnosing power of complex electrical resistivity in a frequency range between 1 mHz and 1 kHz. In our study, the potential of this…

Carotid sinus syndrome is an exaggerated response to carotid sinus baroreceptor stimulation and has been reported in patients with cancer. Here we present a 22-year-old man diagnosed with Hodgkin's lymphoma and admitted with pulmonary sepsis. He evolved with hypotension, bradycardia and syncope after infection control.…

Universities are fostering links and facilitating technology transfer with industries. Industries are transforming rapidly to sustain and ensure businesses prosper well. These have created a dynamic approach by stakeholders towards university-industry collaboration (UIC). However, there is a lack of studies which focus on how the…

Multidisciplinary scientific research collaborations in academic institutions remain at the center of the global innovation system. This article highlights the distinct challenges to developing an effective management strategy that such collaborations pose. These include the fundamental challenge of having the generation of new explicit knowledge…

This paper puts forth a novel methodology for facilities layout planning and optimization, where the fitness evaluation of layout alternatives is automatically performed by employing an artificial neural network trained to preferences of the domain experts. The inherently uncertain, unstructured, and often tacit nature of…

The debate over how to solve the problem of rising health care costs has produced a vast amount of literature in many different fields.  In particular, economists have developed a method known as stochastic frontier analysis which can be used to estimate how inefficiencies within…
