Microplastics (MPs) (plastic particles < 5 mm in size) have become the most ubiquitous type of anthropogenic litter contaminating aquatic environments worldwide, and are capable harming organisms entering food web. Microplastic research has rapidly evolved over several decades, with many studies sampling microplastic surface waters. For sea MPs, different net devices been used. But altho...

A selective sweep describes the reduction of diversity due to strong positive selection. If the mutation rate to a selectively beneficial allele is sufficiently high, Pennings and Hermisson (2006a) have shown, that it becomes likely, that a selective sweep is caused by several individuals. Such an event is called a soft sweep and the complementary event of a single origin of the beneficial alle...

The Barkhausen pattern from the amorphous alloy Fe21Co64B15 showed high sweep-to-sweep reproducibility for most sweeps when driven slowly over a minor hysteresis loop. Small changes in the maximum applied field led to completely different pulse patterns. When driven near saturation the sweep-to-sweep reproducibility was lost. Large features observed on rapid sweeps were also reproducible, but n...

An underwater planar covering problem is studied where the coverage region consists of polygonal cells, and line sweep motion is used for coverage. In many subsea applications, sidescan sonar has become a common tool, and the sidescan sonar data is meaningful only when the sonar is moving in a straight line. This work studies the optimal line sweep coverage where the sweep paths of the cells co...

Garbage Collection frees the programmer from the burden of explicitly deallocating unused data. This facility induces a considerable overhead but also causes some delays that may aaect real-time applications. Guaranteed throughput (with at most short and predictable delays) is needed in many applications such as plane or plant control and requires at least a worst case analysis to identify the ...

In this research, two systems are studied. In the first system, the ratio of poly (methyl methacrylate) (PMMA) and poly (vinyl chloride) (PVC) is varied, whereas in the second system, the composition of PMMA-PVC polymer blends is varied with dopant salt, lithium bis (trifluoromethanesulfonyl) imide (LiTFSI) with a fixed ratio of 70 wt% of PMMA to 30 wt% of PVC. Oscillation tests such as amplitu...

The effectiveness of weight ratio mineral filler to effective bitumen in the fatigue performance asphalt mixture with integral granules was investigated based on experiments mastic (mixture and passed through sieve grade 200). included a dynamic shear rheometer, elastic recovery, linear amplitude sweep tests other mixture, such as indirect tensile resilient modulus test for assessing medium tem...
