Rheophilic fish commonly experience unsteady flows and hydrodynamic perturbations. Instead of avoiding turbulent zones though, rheophilic fish often seek out these zones for station holding. A behaviour associated with station holding in running water is called entraining. We investigated the entraining behaviour of rainbow trout swimming in the wake of a D-shaped cylinder or sideways of a semi...

Being its major component, aggregate can occupy up to three-quarter of the volume of concrete. The structure of aggregate formed in hardened state impacts largely on mechanical and durability properties of concrete. On another hand, physical characteristics of aggregate are primarily assumed to be relevant to granular behavior of aggregate. Therefore, characterization of aggregate is of high re...

Three-dimensional concrete printing (3DCP) is becoming more common in the construction industry nowadays; however, aspect of durability printed not well-studied yet. Frost resistance a very important factor for structures located northern regions. Since air-entraining agents (AEAs) are widely used conventional concrete, this paper focuses on exploring potential using AEAs 3D as well—the main ob...

The evolutionary importance of hybridization as a source of new adaptive genetic variation is rapidly gaining recognition. Hybridization between coyotes and wolves may have introduced adaptive alleles into the coyote gene pool that facilitated an expansion in their geographic range and dietary niche. Furthermore, hybridization between coyotes and domestic dogs may facilitate adaptation to human...

Recent genetic admixture coupled with striking differences in incidence of estrogen receptor (ER) breast cancer subtypes, as well as severity, between women of African and European ancestry, provides an excellent rationale for performing admixture mapping in African American women with breast cancer risk. We performed the largest breast cancer admixture mapping study with in African American wo...

INTRODUCTION Historically, aggregate gradation has been controlled by specifications that call out envelopes for individual fractions, typically the coarse aggregate and the fine aggregate. The shortcoming of this approach is that the gradation of the overall system is not addressed. While it is sensible to stockpile coarse and fine fractions separately to prevent segregation, it is the combine...

Quantitative determination of adulterant in petroleum products viz diesel, petrol and kerosene is great challenge to police, revenue and forensic department. The literature methods are tedious, time consuming with large scope for errors. Viscosity measurement of known admixtures of diesel and kerosene at 40C give linear plot. The viscosity comparisons of unknown sample with known admixtures dir...

Pervious concrete is a green alternative to conventional pavements with minimal fine aggregate and a high void content. Pervious concrete allows water to infiltrate through the pavement, thereby reducing the runoff and the requirement for stormwater management systems. Seashell By-Products (SBP) are produced in an important quantity in France and are considered as waste. This work investigated ...

Programmers have difficulty writing correct multithreaded code, not to mention code that scales well. One way to approach this problem is by offering a transaction construct, and leaving it to the compiler and run-time system to implement efficient synchronization. However, automatically generating efficient synchronization code is an open research problem. In this paper, rather than attempting...
