Abstract This study investigates the impact of bee pollen nutrition on the royal jelly production of honey bees (Apis mellifera).Results demonstrate that pollen diet significantly impacts hypopharyngeal gland (HPG) development and the expression of genes associated with royal jelly biosynthesis.Bees fed Brassica napus pollen exhibited superior HPG
In in vitro conditions, virulence of 91 isolates of species Fusarium genus (F.oxysporum, F.solani, F.acuminatum, F.equiseti, F.arthrosporioides, F.proliferatum, F.avenaceum, F.semitectum, F.tricinctum, F.sporotrichioides and F.graminearum) towards alfalfa seedlings was investigated.Isolates of investigated species originated from diseased alfalfa p
The boiler economizer Drills is a tube heat exchanger located in the final part of the convective duct.In the economizer, water flowing into the boiler is preheated by flue gases.The paper presents the boiler economizer mathematical model with distributed parameters, which can be used to simulate its operation.The developed mathematical model makes
Abstract Among the most cultivated vegetables, brassicas stand out for their economic and social importance, but they also stand out for their requirement for micronutrients, especially cauliflower.In view of the importance of micronutrients in the development of cauliflower, the objective was to study the effect of treating cauliflower seeds with
