It was argued in \cite{DallAgata:2022abm} that the Volkov-Akulov (VA) model as well similar models supergravity and related KKLT string theory, suffer from tachyonic instabilities due to goldstino condensation. The authors of constructed a specific with two unconstrained interacting chiral superfields linearly realized supersymmetry which has an unstable vacuum. They claimed this becomes equiva...

the silver spr chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (aptes) in naoh aqueous solution at different times. silver sputtered slides coated with aptes were immersed in naoh solution, enabling us to produce silver surfaces homogeneously covered with aptes. the surface properties of grafted aptes on sputtered silver surface as a occasion of time were studi...

vilsmeier several diamide derivatives containing 2-chloroquinoline scaffolds were synthesized via ugi reaction of 2-chloroquinoline-3-carboxaldehydes, amines, carboxylic acids and isocyanides. the diversity of these quinolinyl ugi-adducts was increased by using 2-chloroquinoline-3-carboxylic acids as a source of acid. among them, compounds 2d, 2n, 2p, 4a, 4c and 4e displayed moderate to good an...

introduction: for a successful root canal treatment, canal must be obturated apically, coronally and laterally to prevent microleakage and canal reinfection. cold lateral condensation is the most popular method of canal obturation; an easy method with a controlled filling. cold lateral technique disadvantages are presence of void, possible vertical root fracture, and absence of a homogenous and...

In this article we examine how therapeutic culture disseminates into and affects teacher education in Norway. This is done through a close examination of knowledge practices revolving around the term psychosocial. Based on fieldwork data drawing Karin Knorr Cetina’s concept epistemic objects, analyse psychosocial practised, taught, interpreted Norwegian primary secondary institution. We identif...

he movements of cilia and flagella are driven by axonemal dynein ATPases, whose activity must be coordinated in space and time. On page 47, Rupp and Porter provide the first molecular characterization of a component of the dynein regulatory complex (DRC), a crucial but poorly understood regulator of flagellar movement. Besides suggesting a model for DRC assembly, the work identifies a possible ...
