The potential of recycled waste polymeric materials as a substitute for aggregates in concrete has been investigated in the study. Two different types of waste polymer, namely polyurethane formaldehyde (PUF) based packaging waste and high density polyethylene (HDPE) were recycled and used in the experiment. Concrete and masonry poly block specimens were prepared using recycled polymer materials...

Although cluster dwarf galaxies are often neglected due to their faintness, recent observations demonstrate that they are critical for understanding the physical processes behind galaxy and cluster formation. Dwarfs are the most common galaxy type and are particularly abundant in clusters. Recent observational results suggest that dwarfs in dense environments do not all form early in the univer...

Much of this material is not reusable and is usually deposited in a landfill. A study conducted in Wisconsin estimated that construction of a typical single family home in 1992 encumbered waste disposal expenses of over $700.2 The study estimated that between 77,000 and 102,000 cubic yards of construction waste was generated in Dane County alone, at a disposal cost of between $1,000,000 and $1,...

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...

This study presents the research on the chemical analysis and genotoxicity of 28 virgin/recycled paper products in food-contact use. In the chemical analysis, paper products were extracted by reflux with ethanol, and analyzed by gas chromatography/mass spectrometry. 4,4'-bis(dimethylamino)benzophenone (Michler's ketone: MK), 4,4'-bis(diethylamino)benzophenone (DEAB), 4-(dimethylamino)benzopheno...

This perspectives article reviews selected key examples from the field of supramolecular polymer chemistry with specific focus on use dynamic properties that these materials possess in real-world applications. The scope application for fascinating materials, typically networks held place by numerous weak, non-covalent bonds, has proven to be extremely diverse – significant effort past twenty ye...

The management of plastics waste is one the most urgent and significant global problems now. Historically, have been predominantly discarded, mechanically recycled, or incinerated for energy production. However, these approaches typically relied on thermal processes like conventional pyrolysis, which are energy-intensive unsustainable. In this Minireview, some latest advances future trends in c...

This paper describes an attempt to recycle parts of the Czech-to-Russian machine translation system (MT) in the new Czech-to-English MT system. The paper describes the overall architecture of the new system and the details of the modules which have been added. A special attention is paid to the problem of named entity recognition and to the method of automatic acquisition of lexico-syntactic in...

Mechanical properties of supramolecular elastomers (reversible polymer networks with chains connected by and dynamic covalent bonds) differ noticeably from those conventional cross-links. Due to the ability polymers be reprocessed, reshaped, recycled reused, they are considered as potential candidates for green sustainable economy. A simple model is developed viscoplastic behavior at large stra...
