The Article reports the extension of the new original methodology for the analysis and visualization of the bonding interactions, known as the analysis of domain averaged Fermi holes (DAFH), to open-shell systems. The proposed generalization is based on straightforward reformulation of the original approach within the framework of unrestricted Hartree-Fock (UHF) and/or Kohn-Sham (UKS) levels of...

The bonding of glass wafers to aluminum foils in multi-layer assemblies was investigated by the fieldassisted diffusion bonding process. Bonding was effected at temperatures in the range 350–450 C and with an applied voltage in the range 400–700 V under a pressure of 0.05 MPa. The experimental parameters of voltage and temperature were the main factors in influencing the ionic current leading t...

JCO/JULY 2007 P bracket placement is even more important in lingual orthodontics than with labial appliances.1-5 New bracket systems and more flexible wires have eliminated many positioning problems; examples include Kyung’s Mushroom Bracket Positioner,5 the STb system* developed by Takemoto and Scuzzo,6 Wiechmann’s Transfer Optimized Positioning** (TOP), which produces customized archwires wit...

background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...

The hydrogen-bond arrangement within crystalline 2,3,6,7,10,11-hexahydroxytriphenylene tetrahydrate (HHTP·4H2O) undergoes an order-disorder transition at 240 K, as evidenced by the emergence and disappearance of systematic absence violations in variable-temperature single-crystal X-ray diffraction measurements. The low-temperature ordered phase is polar with ferroelectric coupling between neigh...

The purpose of the present study is evaluation of bonding durability of tri-n-butylborane (TBB) initiated resin without 4-methacryloyloxyethyl trimellitate anhydride (4-META) joined to human enamel. Ground human enamel was bonded with TBB resin under six surface conditions: 1) as ground, 2) primed with Teeth Primer, 3) sodium sulfite solution, 4) 4-META solution, 5) acetone-water, and 6) phosph...

We address a unique security vulnerability in long term evolution (LTE) advanced and high speed packet access (HSPA+) wireless networks due to carrier/channel bonding. This vulnerability is shown to result in various amounts of service disruption based on the radio network parameters and the user locations. Typically, channel bonding have been perceived as a means to enhance the bandwidth and t...

The purposes of this study were to investigate the reliability and efficiency of a new evaluation method for resin bonding to root canal dentin, which measures both marginal adaptation and shear bond strength simultaneously, and to determine the effects of root canal irrigants on resin bonding. A wet bonding system (Single Bond) and a self-etching primer system (Clearfil Mega Bond) were employe...
