Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by transmission. Consensus to determine MPs in is lacking and, so, three digestion treatments were evaluated: Alkaline (potassium hydroxide) enzymatic (protease plus lipase) digestions, both combined with a hydrogen peroxide stage; an oxidative method using surfact...

Construction contractors significantly contribute to the progress and success of projects. Contractor prequalification grants tendering rights only competent contractors. The bidding process is one most critical phases in construction industry. project leader must assess general, technical, financial information prepare an accurate proposal select best contractor. In this study, contractor cons...

We propose two multiscale comparisons of graphs using heat diffusion, allowing to compare without node correspondence or even with different sizes. These lead the definition Lipschitz-continuous empirical processes indexed by a real parameter. The statistical properties means such are studied in general case. Under mild assumptions, we prove functional central limit theorem, as well Gaussian ap...

Due to the learning difficulties in mathematics education, a new teaching methodology have been proposed for its improvement. Difficulties indicate that students are not able properly deal with resolving calculations and/or problems. This research examines evolution of attitudes pre-service teachers’ (PSTs) toward when an open calculation based on numbers (OCN) method was followed flipped class...

The pavement Condition Index (PCI) method serves to measure the severity of damage based on 3 main categories: (1) type damage, (2) and (3) amount or density damage. PCI is a numerical index whose values range from 0 100. A value indicates was in very damaged condition, while 100 that still excellent. survey conducted Jalan Tregguli - Welahan along � 1 km divided into several segments identify ...
