Cryogenic wind tunnel activities at the University of Southampton [PDF]

open access: yes
The characteristics and behavior of a 0.3m transonic cryogenic wind tunnel are discussed. The wide band of usable Reynolds numbers is analyzed along with a flow visualization technique using propane.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, Volume 293, Issue 9, Page 2673-2691, May 2026.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Application of numerical optimization to the design of wings with specified pressure distributions [PDF]

open access: yes
A practical procedure for the optimum design of transonic wings is demonstrated. The procedure uses an optimization program based on the method of feasible directions coupled with an aerodynamic analysis program which solves the three-dimensional ...

From Withering to Flourishing: Repairing Academia Through Holistic and Sustainable Care Practices

open access: yesGender, Work &Organization, Volume 33, Issue 3, Page 743-755, May 2026.
ABSTRACT We are scholars and educators committed to embracing care while working within colonialist, neoliberal, and performative academic environments, and we are withering. Our withering is balanced against our inner strength, a fierce belief in connection and community, and a commitment to harnessing the power of transformation.

Status of magnetic suspension technology [PDF]

open access: yes
The reasons for the continuing interest in the Magnetic Suspension and Balance System (MSBS) are highlighted. Typical problems that can arise because of model-support interference in a transonic wind tunnel are shown to illustrate the need for MSBS.
