We discuss the proposal of Hata and Kawano for the tachyon fluctuation around a solution of vacuum string field theory representing a D25 brane. We give a conformal field theory construction of their state – a local insertion of a tachyon vertex operator on the sliver surface state, and explain why the on-shell momentum condition emerges correctly. We also show that a naive computation of the D...

Hydrocyclones are used as pre-filter to reduce suspended particles in irrigation water on the subsequent filters. The aim of study was determine separation efficiency (SE) hydrocyclones, called H1, H2 and H3 according inlet/outlet diameters, at velocities 1.0 (V10), 1.5 (V15) 2.0 (V20) ms-1, sands diameter 0.5 (D05), (D10), (D15), (D20) 2.5 (D25) mm. Therefore, a hydrocyclone laboratory test sy...

We analyze how lower-dimensional bosonic D-branes further decay, using the boundary string field theory. Especially we find that the effective tachyon potential of the lower-dimensional D-brane has the same profile as that of D25-brane. ∗[email protected] †[email protected]

We measure the extent of 100μm galactic emission in two independent galaxy samples using the IRAS 100μm Sky Survey images and constrain the distribution of dust at large (∼<30 kpc) radii. The first sample consists of 90 nearby (v < 6000 km/s) galaxies from the RC3 catalog with similar angular sizes and absolute luminosities (5 ≤ D25 ≤ 10 ′ and −22.5 ≤ MB ≤ − 18) that are isolated in the 100μm i...

X-ray observations have revealed in other galaxies a class of extra-nuclear X-ray point sources with X-ray luminosities of 10–10 erg/sec, exceeding the Eddington luminosity for stellar mass X-ray binaries. These ultra-luminous Xray sources (ULXs) may be powered by intermediate mass black hole of a few thousand M⊙ or stellar mass black holes with special radiation processes. In this paper, we pr...

We consider a new class of solutions (dressed slivers) in Vacuum String Field Theory, which represent D25–branes. For each dressed sliver we introduce a deformation parameter and define a family of states which are characterized by new abelian ∗– subalgebras. We show that this deformation parameter can be used as a regulator: it allows us to define for each such solution a finite norm and energ...

Background: Trans urethral resection of prostate (TURP) under spinal anaesthesia (SAB) in elderly with associated cardio-pulmonary, endocrine or other co-morbidities induces detrimental physiological and psychological stress response to surgery anaesthesia. Proper sedation during can reduces this response. Aim study was compare the characteristics block, hemodynamic changes, postoperative analg...

The interaction of Cu(2+) and Ni(2+) with the N-terminal tail of histone H2B, the 31 amino acid peptide H2B(1-31) (Ac-PEPAKSAPAPKKG(13)SKKAVTKAQKKD(25)GKKRKR-NH(2)), studied by various spectroscopic techniques (UV/Vis, CD, EPR and NMR) are described. The results showed the formation of Cu(2+)-H2B(1-31) complexes above pH 7.3 most probably through the beta-carboxylate group of D25. With the incr...
