The tethered balloon-borne measurement system BELUGA (Balloon-bornE moduLar Utility for profilinG the lower Atmosphere) was deployed over Arctic sea ice 4 weeks in summer 2020 as part of Multidisciplinary drifting Observatory Study Climate expedition. Using BELUGA, vertical profiles dynamic, thermodynamic, aerosol particle, cloud, radiation, and turbulence properties were measured from ground u...

Abstract Beluga whale optimization (BWO) algorithm is a recently proposed population intelligence algorithm. Inspired by the swimming, foraging, and falling behaviors of beluga populations, it shows good competitive performance compared to other state-of-the-art algorithms. However, original BWO faces challenges unbalanced exploration exploitation, premature stagnation iterations, low convergen...

the mucus layer on the skin of fish contain a several of antimicrobial compounds that provide a first line of defense against fish pathogens. this study was conducted to evaluate the effects of different levels of prebiotic grobiotic®-a on antimicrobial activity and some immune parameters of mucus of cultured juvenile beluga (huso huso). for this purpose, four groups of beluga sturgeon with mea...

this study was accomplished to investigate the effect of artemia urmiana nauplii enriched with pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, huso huso.  artemia nauplii were enriched with p. acidilactici at a final concentration of 1010 cfu ml-1 in three time dependent treatments as 3 h (t3), 6 h (t6), 9 h (t9), and one non-enriched artemia as ...

background: hematological studies are valuable diagnostictechniques in the medical care of fish, reflecting the healthcondition and the effects of environmental factors on fish. objectives:due to the high value of sturgeon fish and necessityto recover the brood stock, this study was done to provide dataabout hematological parameters and reproduction normative ofwild brood stock beluga, huso hus...
