The Nested Thermal Envelope Design (NTED™) is an innovative low energy house design that incorporates two thermal envelopes to create a core and perimeter zone. The perimeter acts as a thermal buffer zone, where heat loss from the core and solar gain in the perimeter is recovered to the core via an inter-zone heat pump. In order to optimize heat recovery from the perimeter and minimize temperature stratification, a complete loop is formed around the core living space, through which air may flow in a convective loop. A simplified convective loop was modelled with a commercial CFD software package. Simulations show the convective loop distributes solar gains and reduces temperature stratification in the perimeter. The location of the heat pump in the convective loop was found to affect the DOP by up to 21%.

Fast-atom bombardment mass spectrometry (FAB-MS) was employed for the structural analysis of the core oligosaccharide ofAeromonas hydrophila(Chemotype III) lipopolysaccharide. Positive ion FAB-MS of the underivatized core oligosaccharide gave the protonated molecular ion, confrrming the correct composition in terms of hexoses, heptoses and Kdo which was present as a bicyclic furanosidic lactone. Negative ion FAB-MS gave the deprotonated molecular ion and fragment ions which were derived from more than two cleavage events with charge retention at the reducing and non-reducing terminals. Positive ion F AB-MS of the permethylated core oligosaccharide afforded fragment ions consistent with the defined sequence and branching patterns of the sugar constituents. The electrospray mass spectrum (ESMS) in the positive ion mode of the underivatized core oligosaccharide afforded the protonated molecular ion in the singly and doubly charged forms. Low energy collision-activated dissociation tandem mass spectrometry (CAD MS/MS) analysis of the protonated molecular ion [M+2H]+2provided additional structural data. ESMS of the permethylated and N-acetylated permethylated core oligosaccharides provided useful structural indices and afforded a characteristic pattern for fragmentions resulting from the opening of the methylated bicyclic Kdo furanosidic 1,7- lactone, which was similar to that obtained in the corresponding FAB-MS.

AbstractA novel preparation method of thin films has been successfully developed by high-density ablation plasma produced by pulsed ion-beam evaporation method. The preparation is available with extremely high deposition rate (with cm/s), without heating the substrate, in a vacuum, with good stoichiometry. As an example, the preparation of phosphoresecent SrAl2O4:Eu, Dy thin films will be shown. Furthermore, a new method has been developed of the synthesis of ultrafine nanosize powders by use of microexplosion of pulsed wire discharge. As an example, the synthesis of NiFe2O4 powders will be shown, where two wires of nickel and iron were exploded by pulsed current. In addition, we have succeeded in the preparation of tungsten thin films within via holes in LSI by use of pulsed ion beam-evaporation method. In addition to the huge power per shot, a new machine has been developed of highly repetitive, pulsed power machine for the industrial applications.

An attempt has been made to select the core radius and coupling constant of the Lévy potential for the interaction of two nucleons in order to fit the binding energy of the deuteron and the singlet state neutron–proton scattering length. It was found that these two quantities cannot be fitted simultaneously. For any given choice of coupling constant, a somewhat larger core radius is required to fit the deuteron binding energy than is required for the scattering length. This spin dependence of the core radius does not preclude the possibility of a fit to the low energy data with the Lévy potential.
