the flow characteristics around an elliptic cylinder with an axis ratio of ar=2 located near a flat plate were investigated experimentally. the elliptic cylinder was located on the inside and outside a turbulent boundary layer region whose thickness (δ) is 0.38b. the reynolds numbers based on the height of the cylinder cross-section were 15000 and 30000. measurements of mean velocity and turbul...

individuals with particular genetic backgrounds develop immune responses to wheat proteins and become ‘gluten-sensitised’. mucosal pathology arises through activated mucosal t lymphocytes, resulting in a graded, adverse e reaction between particular genes and wheat proteins. given these varied influences, the marsh classification broadly itemises those stages through which a normal mucosa (mars...

We study several questions involving relative Ricci-flat Kähler metrics for families of log Calabi-Yau manifolds. Our main result states that if $p:(X,B)\to Y$ is a fiber space such $(X\_y, B|{X\_y})$ generically klt, $K{X/Y}+B$ relatively trivial and $p\_\*(m(K\_{X/Y}+B))$ Hermitian flat some suitable integer $m$, then $p$ locally trivial. Motivated by in birational geometry, we investigate th...

We provide examples of flat Laguerre planes of Kleinewillinghöfer type E, thus completing the classification of flat Laguerre planes with respect to Laguerre translations in B. Polster and G.F. Steinke, Results Maths. (2004). These planes are obtained by a method for constructing a new flat Laguerre plane from three given Laguerre planes devised in B. Polster and G. Steinke, Canad. Math. Bull. ...

Let $T=\biggl(\begin{matrix} A&0\\U&B\end{matrix}\biggr)$ be a formal triangular matrix ring, where $A$ and $B$ are rings $U$ is $(B, A)$-bimodule. We first give some computing formulas of projective, injective, flat $FP$-injective dimensions special left $T$-modules. Then we establish (weak) global $T$. It proven that (1) If $U_{A}$ $_{B}U$ $lD(A)\neq lD(B)$, then $lD(T)={\rm m...
