    Notes: Because of its high machining efficiency and good machining quality, ultrasonic aidedhigh-speed lapping with solid abrasive is regarded as a good method of cylindrical machining forengineering ceramics. Compared with conventional lapping, ultrasonic aided high speed lapping hasunique surface topography distribution characteristics for the difference of the surface formationmechanism and material removal mechanism. In the paper, the surface topography characteristics ofengineering ceramics in different lapping mode were researched. Research results show that thelapped surfaces with and without ultrasonic assistance present different surface topographycharacteristics. Under the same lapping mode, the lapped surface topography is distinctly different fordifferent ceramics. With the assistance of ultrasonic vibration, more ductile material removal can beobtained and the surface quality can be improved correspondingly

    Notes: The rate coefficient for the reaction of F+HFCO has been determined over the temperature range 298–368 K by monitoring the appearance rate of HF infrared chemiluminescence using the infrared multiphoton dissociation-infrared chemiluminescence technique. Results, expressed in the Arrhenius form k(T) =4.4±2.6×10−11 exp[−1800±400/RT] cm3 molecule−1 s−1, are compared with the barrier height calculated using ab initio molecular orbital theory. The rate coefficient is theoretically discussed with the aid of essential features of the potential energy surface for the F+HFCO system and the potential importance of the reaction is considered. A rate coefficient for deactivation of excited HF by HFCO is reported as 1.2±0.2×10−12 cm3 molecule−1 s−1.

    Notes: With the help of quantum characteristic functions some exact results are found for two quantum dissipative master equations which contain dissipative Liouvillian operators of the Lindblad-type corresponding to two forms of dissipation mechanisms. Population relaxation is used to demonstrate how dynamic information can be retrieved from these solutions. © 2001 American Institute of Physics.

    Notes: A variational approach is employed to compute the wave function of a single polaron for a two-dimensional Holstein Hamiltonian with arbitrary forms of linear particle–boson interactions and boson dispersion relations. The Toyozawa ansatz is utilized, and generalizations to multiple polarons are outlined. Applications are made to model superradiance in pseudoisocyanine bromide J-aggregates, and to calculate quasiparticle dispersion of an itinerant hole in a two-dimensional antiferromagnet. © 2000 American Institute of Physics.

    Novel insertion sequence-like elements in phytoplasma strains of the aster yellows group are putative new members of the IS3 family (2005)

    Notes: Novel insertion sequence (IS)-like elements were isolated and characterized from phytoplasma strains in the aster yellows (AY) group (16SrI). The IS-like elements were cloned from phytoplasma strains AY1 and NJAY or PCR-amplified from 15 additional strains representing nine subgroups in the AY group using primers based on sequences of the putative transposases (Tpases). All IS-like elements contained sequences encoding similar Tpases of 321 amino acids (320 for strain CPh). Substantial amino acid sequence variability suggested multiple species of Tpases or IS-like elements exist in the AY phytoplasma group. These Tpases have an identical DDE motif that is most similar to the DDE consensus of Tpases in the IS3 family.

    A new iterative procedure for combining direct methods with solvent flattening – dealing with the phase ambiguity in protein crystallography (1997)
    Copenhagen : International Union of Crystallography (IUCr)
    Acta crystallographica 53 (1997), S. 792-794

    Notes: A new procedure for combining direct methods with the solvent-flattening technique is proposed for phasing single isomorphous replacement (SIR) or one-wavelength anomalous scattering (OAS) data of proteins. The new procedure differs from the previous one [Zheng, Zheng, Gu, Mo, Fan & Hao (1997). Acta Cryst. D53, 49–55] in that the direct method not only provides input phases to but also accepts feedback phases from solvent flattening, thus forming an iterative process for breaking the ambiguities and refining the values of phases. The new procedure was tested with the experimental SIR data of the known structure ribonuclease Sa. For the strongest 1000 of the total 7264 refelctions, the mean Fobs-weighted phase error is 7.5 and 9.4° lower than that of the previous procedure and that of solvent flattening alone, respectively.

    Notes: : Xanthan gum coating was used to carry 5% Gluconal Cal, a mixture of calcium lactate and gluconate, and 0.2%α-tocopheral acetate (vitamin E) by weight, respectively. Peeled baby carrots were dipped in the coating solutions, dried, and then stored at 2 °C and 85% relative humidity for up to 3 wk. Calcium and vitamin E contents of the coated samples, per serving (85g), increased from 2.6% to 6.6%, and from 0 to about 67% of the Dietary Reference Intakes (DRI) values respectively. Edible coatings (p 〈 0.05) improved the desirable surface color of carrots without effects (p 〈 0.05) on the taste, texture, and fresh aroma and flavor except for a slightly slippery surface. The β-carotene level in the baby carrots (p 〈 0.05) was not affected by edible coating.

    POLYMERS IN ALUM SLUDGE DEWATERING: DEVELOPMENTS AND CONTROL (2003)

    Notes: The paper (a) discusses the use of polymers for conditioning alum sludge derived from the coagulation of low turbidity coloured waters, and (b) reviews the factors which control the optimum dosage vis a vis individual test methods such as specific resistance to filtration and capillary suction time. It was demonstrated that good estimates of the solids feed could be obtained via the suspended-solids concentration in the flocculators. An algorithm based on water-quality parameters was recommended for planning purposes. Difficulties arising from variations in the solids delivery to the thickeners were shown to influence the separation efficiency. The paper also includes a survey of polymer routeing within a water-treatment plant in which there was multiple polymer use and extensive recycling; this identified a number of quality-control issues and demonstrated the value of polymer measurement.

    Physicochemical and Sensory Qualities of Fresh Pork Chops as Affected by Phosphate, Ascorbate or Sorbate Dipping Prior to Irradiation (1996)

    Notes: Fresh pork chops were dipped for a target absorption of 0.5% sodium tripolyphosphate (STPP), 550 ppm sodium ascorbate (SA), or 0.1% potassium sorbate (PS) prior to irradiation (1.0 kGy). Untreated pork chops, both irradiated and unirradiated, were used as controls. Dipping with STPP decreased drip loss and improved color and lipid stability of irradiated chops and resulted in better tenderness and juiciness scores than undipped, irradiated samples. Also, STPP treated chops had similar or better physicochemical and sensory properties than untreated (no irradiation, no dipping) controls. Dipping with SA or PS had little effect compared with STPP, but improved some sensory qualities.
