Abstract Red brick waste (RBW) powder was used as a reinforcing filler for acrylonitrile butadiene rubber (NBR) preparing eco-friendly composites. The main constituent of this is silica which considered to be one the traditional fillers in industry. So it worthwhile get suitable manner by using NBR. Physicomechanical properties were evaluated, including tensile strength, elongation at break, ha...

The present work investigates the effect of amount carbon black on curing and mechanical properties such as tensile strength, elongation at break, hardness abrasion resistance natural rubber (NR)/ acrylonitrile-butadiene (NBR) blend. For that purpose, a blend composed 65% NR 35% NBR filled with different content N330 was used. results indicate viscosity crosslink density composites increase sco...

A resorcinol resin/water dispersion and a rubber latex are added to 1% 2,2,6,6,-tetramethylpyperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TEMPO-CNFs) dispersed in water, followed by oven drying at 40 °C for 20 h prepare dried TEMPO-CNF/resorcinol resin/latex (DTRL) mixture with weight ratio of 1/0.5/3. DTRL is then nitrile-butadiene (NBR) or carboxy group-containing NBR (X-NBR) sheet,...

The American Burn Association, Children's Burn Foundation, and Christian Medical College in Vellore, India have partnered together to improve pediatric burn care in Southern India. We report the demographics and outcomes of burns in this center, and create a benchmark to measure the effect of the partnership. A comparison to the National Burn Repository is made to allow for generalization and a...

Data Dinas Kesehatan Kabupaten Probolinggo tahun 2020 menyatakan Angka Kematian Bayi (AKB) di sebesar 8,11. tersebut tergolong tinggi jika dibandingkan dengan AKB Provinsi Jawa Timur 6,3. Sehingga perlu dilakukan analisis untuk mengetahui faktor-faktor yang mempengaruhi jumlah kematian bayi 2020. Regresi poisson merupakan sesuai dalam pemodelan kasus data diskrit. Namun regresi mensyaratkan kon...

This work aims to address the heat accumulation issue in electronic components during high-frequency operation through preparation of novel thermally conductive composites. First, polydopamine (PDA) and in-situ growth silver (Ag) nanoparticles are applied for surface modification graphene oxide (GO) carbon nanotube (CNT) prepare [email protected] hybrid filler, respectively. Then, nitrile butad...

Abstract We prepared different thermoplastic elastomers (TPEs) using an internal mixer. investigated the properties of polyurethanes (TPUs) produced from prepolymers with various isocyanate content and two chain extenders to select most appropriate TPU matrix for preparing vulcanizates (TPVs). Based on results, we selected a prepolymer moderate (10%) more flexible 1,6-hexanediol as extender TPV...

The goal of a next basket recommendation (NBR) system is to recommend items for the user, based on sequence their prior baskets. We examine whether performance gains NBR methods reported in literature hold up under fair and comprehensive comparison. To clarify mixed picture that emerges from our comparison, we provide novel angle evaluation methods, centered distinction between repetition explo...
