First, an algorithm was developed to predict PfEIR based on PfPR. Using an assembly of 123 pairs of co-measured PfPR and PfEIR (Protocol S6), we compared several candidate models and selected an empirical (log-linear) model with a correction term for the PfEIR estimation method (Protocol S7) [50,51,19]. Second, a malaria transmission model was utilized to describe the relationship between PfPR ...

One of the practical ways to overcome adverse environmental effects plastic bottle waste is implement bottles into concrete, one most widely used materials in construction industry. Plastic are mainly made polyethylene terephthalate (PET) and can be as a fiber reinforce concrete. In recent years, PET fiber-reinforced concrete (PFRC) has attracted researcher attention, several experimental studi...

in the present research, nonlinear vibration in a coupled system of boron-nitride nano-tube reinforced composite (bnntrc) oil pipes is studied. single-walled boron-nitride nano-tubes (swbnnts) are arranged in a longitudinal direction inside poly-vinylidene fluoride (pvdf) matrix. damping and shearing effects of surrounded medium are taken into account by visco-pasternak model. based on piezoele...

in this research, static stresses analysis of boron nitride nano - tube reinforced composite (bnntrc) cylinder made of poly - vinylidene fluoride (pvdf) subjected to non - axisymmetric thermo - mechanical loads and applied voltage is developed. the surrounded elastic medium is modelled by pasternak foundation. composite structure is modeled based on piezoelectric fiber reinforced composite (pfr...

Over the past decade, significant efforts have been made to develop polymeric-based macro-fibre reinforced concrete (PFRC) for structural applications. Consequently, remarkable growth has reported in use of this type fibres as reinforcement. However, advances quality control methods PFRC lie behind any progress observed polymeric fibre (PF) technology. In particular, cost-effective and efficien...

The size effect on plain concrete specimens is well known and can be correctly captured when performing numerical simulations by using a characterised softening function. Nevertheless, in the case of polyolefin-fibre-reinforced (PFRC), this not directly applicable, since only diagram cannot capture material behaviour elements with different sizes due to dependence orientation factor fibres spec...

Most commercially used piezoelectric materials suffer from certain drawbacks like low output, brittle nature, etc. Thus, they cannot be utilized to their fullest extent in dynamic applications involving actuators, transducers, Surface Acoustic Wave (SAW) devices, and Love wave sensors, among others. The present work focuses on the transference attributes of anti-plane SH a layered structure com...

OBJECTIVES The aim of this study was to evaluate the microleakage of direct restorative composite resin upon the addition of an intermediate glass fiber-reinforced composite (GFRC) layer of various fiber orientations between tooth and particulate filler composite resin (PFRC). MATERIALS AND METHODS Cavities were prepared both on the mesial and distal surfaces of sixty extracted human molars w...
