Context can be defined as all factors that are not part of a quality improvement intervention itself. More research indicates which aspects are 'conditions for improvement', which influence improvement success. However, little is known about which conditions are most important, whether these are different for different quality interventions or whether some become less or more important at diffe...

Definition 2.1. Fix integers d and r. A limit (linear) series on X of degree d and rank r is a collection consisting of an invertible sheaf L on X of degree d on Y and degree 0 on Z, and vector subspaces Vi ⊆ Γ(X,L) of dimension r + 1, for each i = 0, . . . , d, such that φ(Vi) ⊆ Vi+1 and φi(Vi+1) ⊆ Vi for each i. Given a limit series (L, V0, . . . , Vd), we denote by V Y,0 i the subspace of Vi...

In this chapter three issues in the interpretation of the results of school effectiveness research are discussed: criterion choice, effect size and stability of effects. With respect to the first issue the overall conclusion is, that criterion choice and definition depend on the effectiveness perspective and the particular theory one wishes to corroborate. The issues of effect size and stabilit...

The etherification of glycerol with propylene over acidic heterogeneous catalysts, Amberlyst-15, S100, and S200 resins, produced mono-propyl glycerol ethers (MPGEs), 1,3-di- and 1,2-di-propyl glycerol ethers (DPGEs), and tri-propyl glycerol ether (TPGE). The propylation of glycerol over Amberlyst-15 yielded only TPGE. The glycerol etherification with 1-butene over Amberlyst-15 and S200 resins p...

We present new magnetic heat capacity and neutron scattering results for two magnetically frustrated molybdate pyrochlores: S=1 oxide Lu_{2}Mo_{2}O_{7} and S=1/2 oxynitride Lu_{2}Mo_{2}O_{5}N_{2}. Lu_{2}Mo_{2}O_{7} undergoes a transition to an unconventional spin glass ground state at T_{f}∼16  K. However, the preparation of the corresponding oxynitride tunes the nature of the ground state from...

This work describes the synthesis of a novel magnetic graphene oxide composite for removal of Cr(VI) ions. The synthesized nanosorbent were characterized with various techniques such as FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM), elemental analysis and vibrating sample magnetometry (VSM). This material is illustrated to represent a viable sorbent for the removal of Cr(VI...

The role of Vi-capsular polysaccharide (Vi-CPS) in human immunity against infection caused by Salmonella typhi is well known. The downstream process of purification generally causes depolymerization of Vi-CPS to a nonimmunogenic low molecular weight form. In the present study, a standard strain of Sal. typhi Ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 Liter fe...
