Twelve strains of German cockroach, Blattella germanica (Linnaeus) were collected from various locations in Peninsular Malaysia and tested for their susceptibility to three groups of insecticides applied topically. The levels of resistance were low to high (2.8 to 92×) for carbamates (propoxur and bendiocarb), low (2.0 to 7.6×) for organophosphate (chlorpyrifos) and low to moderate (1.0 to 23×)...

Cluster models are used in calculation of (207)Pb NMR magnetic-shielding parameters of α-PbO, β-PbO, Pb3O4, Pb2SnO4, PbF2, PbCl2, PbBr2, PbClOH, PbBrOH, PbIOH, PbSiO3, and Pb3(PO4)2. We examine the effects of cluster size, method of termination of the cluster, charge on the cluster, introduction of exact exchange, and relativistic effects on calculation of magnetic-shielding tensors with densit...

Concentrated sulfuric acid (SA) and nonionic surfactant (C12H25(OCH2CH2)10OH, C12E10) form lyotropic liquid crystalline (LLC) mesophases in a broad range of SA concentrations; the SA/C12E10 mole ratio may vary from 2 to 11 in the LLC mesophases in the presence of a small amount of water. The mesophase is hexagonal at low SA concentration and cubic at higher concentrations. Three different compo...

A second generation of the Particle Beam Optics Laboratory has been developed with an emphasis on applications to problems in accelerator optimization. The new version of the software incorporates several enhancements that significantly extend the capabilities of the first release of PBO Lab described at EPAC98. Several charged particle optics programs, including TRANSPORT, TURTLE, MARYLIE and ...

A field strain of the German cockroach (Melia), collected from the kitchen of a hotel in Kuala Lumpur, Malaysia demonstrated moderate resistance to bendiocarb and low resistance to propoxur and deltamethrin when tested with modified W.H.O. glass jar method. Low resistance was also detected when the strain was tested with DDT. Resistance level to bendiocarb and deltamethrin was partially suppres...

Long lasting pyrethroid treated bednets are the most important tool for preventing malaria. Pyrethroid resistant Anopheline mosquitoes are now ubiquitous in Africa, though the public health impact remains unclear, impeding the deployment of more expensive nets. Meta-analyses of bioassay studies and experimental hut trials are used to characterise how pyrethroid resistance changes the efficacy o...

The knowledge-based view (KBV) of firms has received increasingly attention. A relatively unexplored area is knowledge transfer in project-based organizations (PBOs). The PBO relies upon combining expertise from several internal and external parties in order to deliver their own capabilities in a one-off process. Knowledge over projects is difficult to transfer due to the unique character of pr...

OBJECTIVE To evaluate the efficacy and safety of perampanel in patients with drug-resistant partial seizures after the conversion from double-blind placebo in three phase III studies to open-label perampanel, and to assess the impact of perampanel titration rates through a comparison of weekly vs biweekly dose increases. METHODS Patients who completed the three multinational, double-blind, pl...
