The formal conception of computation (FCC) holds that computational processes are not sensitive to semantic properties. FCC is popular, but it faces well-known difficulties. Accordingly, authors such as Block and Peacocke pursue a ‘semantically-laden’ alternative, according to which computation can be sensitive to semantics. I argue that computation is insensitive to semantics within a wide ran...

A tubeless siphon was created by sucking a 1% aqueous Polyox† solution laden with particles from a beaker into a cylinder by moving a piston. The piston speed and particle concentration were varied. At very high rates of withdrawal, all the liquid could be removed before the siphon broke. In this case, the beaker was completely cleaned without a trace of liquid. The addition of small concentrat...

Posttraumatic growth (PTG) is a person’s mental experience of positive psychological changes induced by encountering extremely challenging situations. This study aimed to investigate the concept of posttraumatic growth and its relationship with quality of life (QOL) in cancer patients. This is a descriptive cross-sectional study. The study population consisted of cancer patients referred to two...

In this paper, the sediment-laden flow around a circular cylinder is numerically simulated in order to obtain better understanding of hydrodynamics associated. A range of cases with different Reynolds numbers (Re) are studies. The effects of the concentration of the sediment on the drag coefficient are investigated. Results show that due to the fact that the laden sand particle colliding the cy...

Ecotourism in protected areas facilitates responsible travel to natural places that conserve the environment, deliver economic benefits local communities, and offer interpretation education visitors. Proper planning sufficient monitoring of ecotourism sustainability indicators is needed manage visitor activities areas. Therefore, identifying major impacts mitigating them early stages developmen...

In this article, we define a new class of graphs, the fat-extended P4-laden graphs, and we show a polynomial time algorithm to determine the Grundy number of the graphs in this class. This result implies that the Grundy number can be found in polynomial time for any graph of the following classes: P4-reducible, extended P4-reducible, P4-sparse, extended P4-sparse, P4-extendible, P4-lite, P4-tid...

Microbes are known to affect ecosystems and communities as decomposers, pathogens, and mutualists. However, they also may function as classic consumers and competitors with animals if they chemically deter larger consumers from using rich food-falls such as carrion, fruits, and seeds that can represent critical windfalls to both microbes and animals. Microbes often use chemicals (i.e., antibiot...
