Natural Killer (NK) cells comprise a group of specialized innate lymphoid endowed with multiple cytotoxicity mechanisms while also harnessed the ability to enhance other immune cytokine production. This exclusive advantage them recognize and eliminate virally infected tumour has been unmasked for decades, previous clinical trials are successfully tested both efficacy safety. With emerging strat...
The diagnosis of land degradation requires a deep understanding ecosystem functioning and evolution. In dryland systems, in particular, research efforts must address the redistribution scarce resources for vegetation, context high spatial heterogeneity non-linear response. This fact explains prevalence eco-hydrological perspectives interested runoff processes and, more recent, focused on connec...
Species surrogates, the use of particular species to index habitat condition or to represent ecological assemblages are commonly identified in many ecosystems, but are less tested, and therefore less employed in estuaries. Estuaries provide important ecosystem goods (e.g. harvestable species) and services (e.g. carbon processing, coastal armouring), but require protection from multiple human ac...
Sandy beaches comprise one of the most important coastal resources worldwide, providing habitats to threatened vertebrates, supporting underappreciated invertebrate biodiversity, and delivering crucial ecosystem services and economic benefits to mankind. Monitoring of the natural resource condition of sandy beaches and assessments of the ecological impacts of human disturbance are, however, rar...
Gully erosion is a major environmental problem, posing significant threats to sustainable development. However, insights on techniques prevent and control gullying are scattered incomplete, especially regarding failure rates effectiveness. This review aims address these issues contribute more successful gully prevention strategies by synthesizing the data from earlier studies. Preventing format...
Natural river channels that are sediment supply limited due to upstream water management practices and/or flow regulation often subject in-channel bed degradation and surface restructuring during natural flood hydrographs or controlled releases from dams. The heterogeneity of sizes present in these means different size classes transported more actively parts the hydrograph. A series laboratory ...
The numerical 1-D HEC-RAS modelling tool was supported by the estimation of sieve curve changes procedure to measure scale predicted discharges along a stretch stream in southern Poland on Olkusz Upland. calibrated mountain streams during high-stage events, using radiotracer application bedload transport. Particular terrain hypsometry, created dissolution limestone, forced deep erosion river va...
of Research Findings Alternative tillage and cropping systems are sought for reducing dust emissions and improving air quality in the Pacific Northwest dryland cropping region. The purpose of this study was to modifiy the conventional rodweeder that would facilitate the armouring of the soil surface with straw and large aggregates otherwise buried below the soil surface. Several modifications w...
In many places, sandy coastlines and their associated assets are at high risk of erosion flooding, with this increasing under climate change sea level rise. context, dynamic cobble berm revetments represent a potentially sustainable protection technique to armour beaches, reduce wave runup protect the hinterland against attack. However, behaviour performance such structures is not well understo...
