A CONJOINT ANALYSIS OF PAPER DEMAND BY COMMERCIAL GRAPHIC DESIGNERS

Conjoint analysis was used to evaluate the preferences of graphic designers toward kenaf paper. Results indicate that price is of overwhelming importance to designers in their purchasing decisions regarding paper stock. If priced competitively with existing wood and recycled papers, kenaf products should gain market share among designers.Demand and Price Analysis,

Supervillin Is a Component of the Hair Cell\u27s Cuticular Plate and the Head Plates of Organ of Corti Supporting Cells

The organ of Corti has evolved a panoply of cells with extraordinary morphological specializations to harness, direct, and transduce mechanical energy into electrical signals. Among the cells with prominent apical specializations are hair cells and nearby supporting cells. At the apical surface of each hair cell is a mechanosensitive hair bundle of filamentous actin (F-actin)-based stereocilia, which insert rootlets into the F-actin meshwork of the underlying cuticular plate, a rigid organelle considered to hold the stereocilia in place. Little is known about the protein composition and development of the cuticular plate or the apicolateral specializations of organ of Corti supporting cells. We show that supervillin, an F-actin cross-linking protein, localizes to cuticular plates in hair cells of the mouse cochlea and vestibule and zebrafish sensory epithelia. Moreover, supervillin localizes near the apicolateral margins within the head plates of Deiters\u27 cells and outer pillar cells, and proximal to the apicolateral margins of inner phalangeal cells, adjacent to the junctions with neighboring hair cells. Overall, supervillin localization suggests this protein may shape the surface structure of the organ of Corti

Fusion of mercury a new certified standard for differential scanning calorimetry

From the results of adiabatic-calorimetric measurements, mercury has been certified as a standard reference material for temperature and enthalpy of fusion for differential scanning calorimetry. The fusion temperature is (234.30 +/- 0.03) K and the molar enthalpy of fusion is (2.301 +/- 0.001) kJ[middle dot]mol-1. Adiabatic-calorimetric measurements made by heating continuously at 0.00017 K[middle dot]s-1 through the transition showed a fusion temperature of (234.32 +/- 0.03) K. Differential-scanning-calorimetric measurements gave a fusion temperature of (234.34 +/- 048) K.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28706/1/0000526.pd

Nuclei in Strongly Magnetised Neutron Star Crusts

We discuss the ground state properties of matter in outer and inner crusts of neutron stars under the influence of strong magnetic fields. In particular, we demonstrate the effects of Landau quantization of electrons on compositions of neutron star crusts. First we revisit the sequence of nuclei and the equation of state of the outer crust adopting the Baym, Pethick and Sutherland (BPS) model in the presence of strong magnetic fields and most recent versions of the theoretical and experimental nuclear mass tables. Next we deal with nuclei in the inner crust. Nuclei which are arranged in a lattice, are immersed in a nucleonic gas as well as a uniform background of electrons in the inner crust. The Wigner-Seitz approximation is adopted in this calculation and each lattice volume is replaced by a spherical cell. The coexistence of two phases of nuclear matter - liquid and gas, is considered in this case. We obtain the equilibrium nucleus corresponding to each baryon density by minimizing the free energy of the cell. We perform this calculation using Skyrme nucleon-nucleon interaction with different parameter sets. We find nuclei with larger mass and charge numbers in the inner crust in the presence of strong magnetic fields than those of the zero field case for all nucleon-nucleon interactions considered here. However, SLy4 interaction has dramatic effects on the proton fraction as well as masses and charges of nuclei. This may be attributed to the behaviour of symmetry energy with density in the sub-saturation density regime. Further we discuss the implications of our results to shear mode oscillations of magnetars.Comment: presented in "Exciting Physics Symposium" held in Makutsi, South Africa in November, 2011 and to be published in a book by Springer Verla

Comparison of heat capacities measured by adiabatic calorimetry and by scanning calorimetry: thermodynamic properties of 9-methylcarbazole at temperatures between 4 K and 345 K

We have measured the heat capacity of 9-methylcarbazole at 4[less-than-or-equals, slant]T/K[less-than-or-equals, slant]345 by adiabatic calorimetry and compared it with that measured by differential scanning calorimetry (d.s.c.) at 120[less-than-or-equals, slant]T//K[less-than-or-equals, slant]355. The d.s.c. measurements were made by both a scanning method and by an enthalpic, or intermittent heating, method. The molar heat capacities Cp, m determined by d.s.c. agreed with the values obtained by adiabatic calorimetry within the usual error associated with d.s.c., about 0.01 · Cp, m. No anomalies or transitions were observed up to 350 K. Thermodynamic functions obtained from these values are tabulated at selected temperatures.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30183/1/0000568.pd

Zebrafish TRPA1 Channels Are Required for Chemosensation But Not for Thermosensation or Mechanosensory Hair Cell Function

Transient receptor potential (TRP) ion channels have been implicated in detecting chemical, thermal, and mechanical stimuli in organisms ranging from mammals to Caenorhabditis elegans. It is well established that TRPA1 detects and mediates behavioral responses to chemical irritants. However, the role of TRPA1 in detecting thermal and mechanical stimuli is controversial. To further clarify the functions of TRPA1 channels in vertebrates, we analyzed their roles in zebrafish. The two zebrafish TRPA1 paralogs are expressed in sensory neurons and are activated by several chemical irritants in vitro. High-throughput behavioral analyses of trpa1a and trpa1b mutant larvae indicate that TRPA1b is necessary for behavioral responses to these chemical irritants. However, TRPA1 paralogs are not required for behavioral responses to temperature changes or for mechanosensory hair cell function in the inner ear or lateral line. These results support a role for zebrafish TRPA1 in chemical but not thermal or mechanical sensing, and establish a high-throughput system to identify genes and small molecules that modulate chemosensation, thermosensation, and mechanosensation
