Evaluation of winter wheat varieties based on grain quality indicators in northern Ukraine

open access: yesНаукові доповіді Національного університету біоресурсів і природокористування України
The study was devoted to assessing the impact of hydrothermal conditions on the formation of grain quality indicators of winter wheat varieties in northern Ukraine. The relevance of the work was determined by the intensification of climatic fluctuations,

The role of time-history effects in the formulation of the aerodynamics of aircraft dynamics [PDF]

open access: yes
The scope of any aerodynamic formulation proposing to embrace a range of possible maneuvers is shown to be determined principally by the extent to which the aerodynamic indicial response is allowed to depend on the past motion.

State-space model identification and feedback control of unsteady aerodynamic forces

open access: yes, 2014
Unsteady aerodynamic models are necessary to accurately simulate forces and develop feedback controllers for wings in agile motion; however, these models are often high dimensional or incompatible with modern control techniques.

Tobak – ett av de största folkhälsoproblemen

open access: yesSocialmedicinsk tidskrift, 2016
Användningen av tobak har blivit ett av de största folkhälsoproblemen. Numera är det allmänt känt att rökning ger upphov till flera livshotande och funktionsnedsättande sjukdomar. Samhällskostnaderna för dessa överskrider vad tobakskonsumenterna betalar i tobaksskatt. Det tobakspreventiva arbetet har många facetter.
