GENERATION OF THERMAL CONVECTION IN THE MOSS-SNOW LAYER ON THE COAST OF THE GULF OF GRENFJORD (WEST SVALBARD)

Generation of thermal convection in the moss-snow layer on the coast of the Gulf of Grenfjord (West Svalbard)

The significant part of the Arctic soils is covered by vegetation all year round, to which a layer of snow is added in winter.Both layers have a similar structure, consisting of a skeleton (organic and ice, respectively) and air-saturated pores, and, thus, form a unified system with high heat-insulating properties.But, with the temperature gradient

Haste makes waste: accelerated molt adversely affects the expression of melanin-based and depigmented plumage ornaments in house sparrows.

Many animals display colorful signals in their integument which convey information about the quality of their bearer.Theoretically, these ornaments incur differential production and/or maintenance costs that enforce their honesty.However, the proximate mechanisms of production costs are poorly understood and contentious in cases of non-carotenoid-b

Aerodynamic Forces Affecting the H-Rotor Darrieus Wind Turbine

Darrieus LOCK wind rotor is a vertical axis wind turbine that is a very promising kind of wind converters at remote and domestic locations that have soft and weak wind potential and speed, but from the quantitative comparison with horizontal axis wind turbines, this type of turbines has a weak performance.Additional researches are still needed to d
