To improve the ductility and seismic performance of a double coupling beam, authors applied polyethylene terephthalate (PET) sheet steel tube to form fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular (DST) composite beams. A low-cyclic reversed experimental program was carried out which factored in member form, diameter, construction methods. The results indicate that energy dis...

pp/pep blends, because of different solubility factors, are incompatible. the aim of this research was to use pp-g-ma compatibilizer in a two-component blend. after preparing this compatibilizer in internal mixer and investigating different parameters on producing process, optimum compatibilization was obtained. pp/pet (60/40) blend fibers with different percentages of this compatibilizer in tw...

In this paper, recycled cellulose diacetate (rCDA) derived from cigarette butts was used as a fiber stabilizer to develop stone mastic asphalt (SMA) mixtures. The characterizations of rCDA were investigated by scanning electron microcopy (SEM), Fourier transform infrared spectrometer (FTIR), and thermogravimetric analyzer (TGA). Volumetric stability, temperature moisture fatigue performance SMA...

The interest in recycled carbon fiber (rCF) is growing rapidly and the supply chain for these materials gradually being established. However, processing routes, material intermediates properties of rCF composites are less understood designers to adopt them into practice. This paper provides a practical pathway rCFs conjunction with low cost and, most part, commodity thermoplastic resins, namely...

in this paper, we review novel techniques in the emerging field of spatiotemporal 4d pet imaging. we will discuss existing limitations in conventional dynamic pet imaging which involves independent reconstruction of dynamic pet datasets. various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that utilize iterative temporal smooth...

Plastik merupakan kemasan yang banyak digunakan dalam berbagai sektor kehidupan. Sampah plastik telah lama tercemar di perairan, akan mengalami degradasi menjadi partikel-partikel kecil disebut mikroplastik. Penelitian ini bertujuan untuk mengetahui adanya kandungan mikroplastik pada air dan sedimen Pantai Teluk Lampung Kabupaten Pesawaran, Provinsi Lampung. Pengambilan sampel dilakukan tiga st...
