The effect of particle size on shear strength of granular materials are investigated using direct shear tests. Small direct shear test (60 mm by 60 mm by 24 mm deep) were conducted for particles passing the sieves with opening size of 2.36 mm. Meanwhile, particles passing the standard 20 mm sieves were tested using large direct shear test (300 mm by 300 mm by 200 mm deep). The large direct shea...

The necessity of the inclusion second invariant left Cauchy-Green deformation tensor B, namely I2, in strain energy function W rubber-like materials is analysed. Universal relationships that underline such are revisited, and experimental data examined to establish trends variation ?W/?I2. Corroborated by established trends, we consider (meso)structural arguments devise a plausible approach for ...

We report a new type of photofragment caging reaction that is only possible because of the strong solvent-induced perturbation of the inherent electronic structure of the chromophore. The photoexcitation of I2 2 at 395 nm promotes it to a dissociative state correlating with I1I*(P1/2), the only near-ultraviolet dissociation channel for unsolvated I2 . In I2 ~CO2!n and I2 ~OCS!n clusters, intera...

BACKGROUND We explored the role that inhibitory heterotrimeric G-proteins play in ventricular arrhythmia. METHODS AND RESULTS Mice with global genetic deletion of Galpha(i2) [Galpha(i2) (-/-)] were studied and found, based on telemetry, to have a prolonged QT interval on surface ECG when awake. In vivo electrophysiology studies revealed that the Galpha(i2) (-/-) mice have a reduced ventricula...

To quantify the importance of the carotid sinus baroreceptor reflex and the interaction with epinephrine infusion on total pulmonary vascular capacity and resistance, I have simultaneously measured total pulmonary vascular compliance, changes in pulmonary blood volumes, and changes in resistances in seven sodium pentobarbital-anesthetized dogs. A preparation was used that bypasses the right and...

PCR Conditions: PCR was performed in a total volume of 20 microliters with 200 ng of genomic DNA, 8 pmoles of each primer, 2 mM MgCl2, 200 mM dNTP, 50 mM KC1, 5 mM Tris-HCl, pH 8.3, 0.01% gelatin, 0.5 U Taq polymerase (Boehringer). Primer Ang5 was 5' end labeled with P 7-ATP with the resulting specific activity 0.1-0.05 /iCi/pmol. Amplification was for 35 cycles with denaturation at 94°C 1 min,...

Let i1 ≥ i2 ≥ i3 ≥ 1 be integers. An L(i1, i2, i3)-labelling of a graph G = (V, E) is a mapping φ : V → {0, 1, 2, . . .} such that |φ(u)− φ(v)| ≥ it for any u, v ∈ V with d(u, v) = t, t = 1, 2, 3, where d(u, v) is the distance in G between u and v. The integer φ(v) is called the label assigned to v under φ, and the difference between the largest and the smallest labels is called the span of φ. ...

We report the dispersed fluorescence spectra of the linear and the previously well-studied T-shaped isomers of Ar–I2 following B←X optical excitation for vpump516– 26, below the I2 dissociation limit. The linear isomer has a continuum excitation spectrum. For excitation at the highest pumping energy (vpump526), the product vibrational state distribution is nearly identical to that observed for ...

The specialty of radiation therapy has increased in complexity over the years, yet as technology improves, the goal of improving outcomes while decreasing toxicity remains critical. Malignant gliomas remain among the most devastating of all malignancies, yet as conventional treatments (surgery, radiation, and chemotherapy) have become optimized overall survival has improved. The underlying mole...
