Empowered Virtual Synchronous Generator Based Control Scheme for Improved Transient Response and Reduced Nuisance Tripping in Stable Microgrids

IEEE Access
Multiloop voltage-controlled virtual synchronous generator (VSG) based control scheme is recently popular in forming stable microgrids. This scheme deploys traditional VSG (TVSG) control for power controllers in the outermost loop and proportional ...

Mikrobiološki rizici sigurnosti i kvalitete tijekom proizvodnje piva [PDF]

Kemija u Industriji
Pivo se smatra relativno stabilnim proizvodom s obzirom na mikrobno kvarenje. Kemijski sastav piva ne pogoduje rastu većine mikroorganizama, što je povezano s niskom pH-vrijednosti i niskim udjelom fermentabilnih ugljikohidrata te sadržajem alkohola ...

Double scaling and intermittency in shear dominated flows

, 2001
The Refined Kolmogorov Similarity Hypothesis is a valuable tool for the description of intermittency in isotropic conditions. For flows in presence of a substantial mean shear, the nature of intermittency changes since the process of energy transfer is ...

Are non‐economic goals and financial performance friends or foes in hybrid ventures? A duality perspective on academic spin‐offs

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary This study draws on the behavioral theory of the firm and a duality perspective to investigate the impact of founders' focus on academic goals on the financial performance of academic spin‐offs (ASOs)—a specific type of hybrid venture. We theorize that such relationship follows an inverse U‐shaped curve and is moderated by the

Do digital platforms create entrepreneurial opportunities? Evidence from marginal areas

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary This article enters the debate on the effects of digital platforms on entrepreneurial opportunities by estimating whether the entry of a home‐sharing platform shapes entrepreneurial decisions in marginal areas. We add a novel perspective to the literature, as we contend that when economic conditions are unfavorable, digital ...

Photochemical Cyclization of Tertiary Buta‐2,3‐dienamides to β‐Lactams Upon Triplet Energy Transfer

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Energy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...
