Technology that is developed for or adopted by the recreational fisheries sector (e.g., anglers and the recreational fishing industry) has led to rapid and dramatic changes in how recreational anglers interact with fisheries resources. From improvements in finding and catching fish to emulating their natural prey and accessing previously inaccessible waters, to anglers sharing their exploits with others, technology is completely changing all aspects of recreational fishing. These innovations would superficially be viewed as positive from the perspective of the angler (aside from the financial cost of purchasing some technologies), yet for the fisheries manager and policy maker, technology may create unintended challenges that lead to reactionary or even ill-defined approaches as they attempt to keep up with these changes. The goal of this paper is to consider how innovations in recreational fishing are changing the way that anglers interact with fish, and thus how recreational fisheries management is undertaken. We use a combination of structured reviews and expert analyses combined with descriptive case studies to highlight the many ways that technology is influencing recreational fishing practice, and, relatedly, what it means for changing how fisheries and/or these technologies need to be managed-from changes in fish capture, to fish handling, to how anglers share information with each other and with managers. Given that technology is continually evolving, we hope that the examples provided here lead to more and better monitoring of technological innovations and engagement by the management and policy authorities with the recreational fishing sector. Doing so will ensure that management actions related to emerging and evolving recreational fishing technology are more proactive than reactive.This paper is associated to investigate a stochastic SEIAQHR model for transmission of Coronavirus disease 2019 that is a recent great crisis in numerous societies. This stochastic pandemic model is established due to several safety protocols, for instance social-distancing, mask and quarantine. Three white noises are added to three of the main parameters of the system to represent the impact of randomness in the environment on the considered model. Also, the unique solvability of the presented stochastic model is proved. Moreover, a collocation approach based on the Legendre polynomials is presented to obtain the numerical solution of this system. Finally, some simulations are provided to survey the obtained results of this pandemic model and to identify the theoretical findings.Due to the increased concern for the environment, sustainable construction materials are getting increased attention. Wood is considered a renewable, sustainable construction material. The problem with wood is that it is a fire-prone material. With an increasing number of wildland-urban interface (WUI) fires recently, it is important to consider that wood buildings are in danger to be ignited as well as may produce new sources of ignition due to firebrand production. Experiments were performed to investigate cedar roof covering effects of firebrand production from roof assemblies. Two wind speeds, 6 m/s and 8 m/s were selected for this experiment for a comparison with literature. The wood materials used were untreated cedar shingles, untreated cedar shakes, fire retardant cedar shingles and fire retardant cedar shakes. The roof assembly with fire retardant cedar shakes applied produced little or no firebrands under both wind speeds tested. Roof coverings fitted with cedar siding produced more variety of firebrands compared to only base sheathing materials. The mass and the projected area of firebrands were found to have a linear relationship. The firebrand coefficient was used for comparison. With attendant increase in wind speed, the firebrand coefficient increased in this study.We continuously talk about autonomous technologies. But how can words qualifying technologies be the very same words chosen by Kant to define what is essentially human, i.e. being autonomous? The article focuses on a possible answer by reflecting upon both etymological and philosophical issues, as well as upon the case of autonomous vehicles. Most interestingly, on the one hand, we have the notion of (human) "autonomy", meaning that there is a "law" that is "self-given", and, on the other hand, we have the notion of (technological) "automation", meaning that there is something "offhand" that is "self-given". Yet, we are experiencing a kind of twofold shift on the one hand, the shift from defining technologies in terms of automation to defining technologies in terms of autonomy and, on the other hand, the shift from defining humans in terms of autonomy to defining humans in terms of automation. From a philosophical perspective, the shift may mean that we are trying to escape precisely from what autonomy founds, i.e. individual responsibility of humans that, in the Western culture, have been defined for millennia as rational and moral decision-makers, even when their decisions have been the toughest. More precisely, the shift may mean that we are using technologies, and in particular emerging algorithmic technologies, as scapegoats that bear responsibility for us by making decisions for us. Moreover, if we consider the kind of emerging algorithmic technologies that increasingly surround us, starting from autonomous vehicles, then we may argue that we also seem to create a kind of technological divine that, by being always with us through its immanent omnipresence, omniscience, omnipotence and inscrutability, can always be our technological scapegoat freeing us from the most unbearable burden of individual responsibility resulting from individual autonomy.Most recently, the whole world is struggling against the virulent pandemic COVID-19. click here Due to the unbounded global spread of the disease, having biosensors with high performance such as high sensitivity and accuracy is of utmost importance. In this paper, the effects of various parameters on the behaviors of micro-biosensors are investigated in order to enhance their performance. These parameters are related to the geometry and material, and they are assumed to be gradually changing in the longitudinal direction of the biosensor according to a power law. Therefore, they are called functionally graded geometrical and material parameters. Another aspect is when considering microcantilever-based biosensors, the main behavior parameter is the deflection at the free end. In the analyses, the influences of the surface stress and van der Waals intermolecular forces are taken into account. Also, the total energy of the beam, which is the combination of the van der Waals energy and the elastic strain energy, is accomplished.
