case studies; fisheries; models; population dynamics; population structure
Abstract:
... Understanding population dynamics is essential for achieving sustainable and productive fisheries. However, estimating recruitment in a stock assessment model involves the challenging task of identifying a self-sustaining population, which often includes representing complex geographic structure. A review of several case studies demonstrated that alternative stock assessment models can influence e ...
... Despite their generally negative attitude toward food waste, consumers often pursue goals that can inhibit their intention to reduce food waste. Identifying these goals that inhibit consumers’ intention to reduce food waste is essential for the development of successful public policy and retail approaches designed to curb or reduce household food waste. First, we conducted semi-structured qualitat ...

... The stringent response alarmones pppGpp and ppGpp are essential for rapid adaption of bacterial physiology to changes in the environment. In Escherichia coli, the nucleosidase PpnN (YgdH) regulates purine homeostasis by cleaving nucleoside monophosphates and specifically binds (p)ppGpp. Here, we show that (p)ppGpp stimulates the catalytic activity of PpnN both in vitro and in vivo causing accumula ...

... Obesity and up-regulated lipolysis are commonly associated with increased free fatty acid (FFA) concentrations, predominantly palmitic acid (PA), in blood and ovarian follicular fluid, which have been strongly linked with reduced oocyte quality. Mitochondria are known to play a central role in regulating cellular stress responses to lipotoxicity, which is well described in somatic cells. Although ...
... The northern white rhinoceros (NWR; Ceratotherium simum cottoni) is critically endangered. Testicular tissue (TT) of an NWR that died at 46 years was cryopreserved and stored. Spermatogonial stem cells (SSC) have been isolated from TT and, following transplantation or in vitro culture, differentiated into mature spermatozoa. These SSC have been phenotypically characterised by the expression of mar ...

Abstract:
... Increased urbanization and climate change have resulted in the intensification of the urban heat island (UHI) effect, particularly in tropical cities. One of the main causes of UHI is the man-made urban surfaces influencing the radiation budget by absorbing, reflecting, and emitting radiation at various wavelengths. The radiative budget of a city is directly influenced by the urban geometry, surfa ...
... The Government of Canada has implemented measures to reduce greenhouse gas emissions, including a carbon tax and its proposed Clean Fuel Standard. Alberta's Oil Sands industry, arguably one of Canada's largest and most energy intensive industries, has made significant progress towards improving energy efficiency and reducing its fossil energy footprint, including investigating options for integrat ...
... In Eastern Mediterranean history, 1200 BCE is a symbolic date. Its significance is tied to the important upheavals that destabilised regional-scale economic systems, leading to the dislocation of mighty Empires and, finally, to the “demise” of a societal model (termed “the Crisis Years”). Recent studies have suggested that a centuries-long drought, of regional scale, termed the 3.2 ka BP event, co ...

The NiCo nanoclusters can provide an excellent conductivity and high activ ...
... Lobaria pulmonaria is a widespread epiphytic foliose lichen that exhibits a prominent reticulum, a structure that has a presumed role in mechanical support and water capture. Using photogrammetry, thallus topography was digitally modelled in three dimensions to calculate 3D surface area (A₃D), which was consistently greater than areas extracted from projected images (A₂D). The A₃D:A₂D ratio, a pro ...
... No human face is like another, not even in monozygotic twins, which makes the face one of the most individualizing characteristic. It is for this reason that the human face is commonly used for identification purposes and police officers take portrait photographs of arrested persons, so-called mug shots. The disadvantage of these 2D mug shots is that the perspective, in which they are taken (usual ...

... 5-(Chloromethyl)furfural (CMF) is a carbohydrate-derived platform molecule that is gaining traction as a more practical alternative to 5-(hydroxymethyl)furfural (HMF). This perspective introduces the chemocatalytic approach to biorefining as the driving force behind the development of multifunctional chemical platforms. The main advantage of CMF over HMF is that it can be produced in high yield un ...

Abstract:
... To mitigate the effects of the intermittent generation of renewable energy sources, reliable and efficient energy storage is critical. Since nearly 80% of households energy consumption is destined to water and space heating, thermal energy storage is particularly important. In this context, we propose and validate a new model for one of the most efficient heat storage systems: stratified thermal s ...
