The title compound, C19H17ClN4, was obtained from the reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropylamide as an Queen Panel Headboard unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring.The 2,5-dihydro-1,2,4-triazine ring is e
This study presents a study on the time when the short-circuit fault current in an MV distribution network will cross the zero point in the presence of DC offset affected by the local synchronous and/or induction machines.The motivation of the study is to examine using thyristors to bypass a series compensator in the network while the subsequent tu
The purpose of the research is studying the spread of cryptosporidiosis in calves and assessment of the extenseeffectiveness of antiprotozoal drugs.Materials and methods.The spread, seasonal and age-specific trends of cryptosporidiosis was studied on 395 spontaneously infected animals of five age groups.The first group was formed of calves up to 10
For microgrids (MGs) with multi parties, a good idea is to build a Stackelberg model for decision-making strategies and energy management.In previous studies, decision parameters in the utility function of each distributed generator (DG) were not determined according to their preferences or roles, which greatly limited their activities in the tradi
BackgroundA cartilage wedge block and covering flap are standard procedures for firm elevation of the ear in microtia correction.However, using costal cartilage for elevation of the reconstructed auricle can be insufficient, and the fixed cartilage wedge block may be absorbed or may slip out.Furthermore, elevating covering flaps is time-consuming a
