We present a set of formulae to extract the gluon distribution function from the deep inelastic structure function F2 and its derivative dF2/dlnQ 2 at small x in the leading and next-to-leading order of perturbation theory. The detailed analysis is given for new HERA data. The values of the gluon distribution are found in the range 10 ≤ x ≤ 10 at Q = 20 GeV E-mail:[email protected] E-mai...

Sandstones sampled from Patti Formation, Southern Bida Basin, were studied geochemically using Inductively Coupled Plasma Atomic Emission Spectrophotometer (ICP-AES) and an Mass Spectrometry (ICP-MS) technique to evaluate their weathering tectonic setting as well deduce the paleo-climatic conditions that existed during deposition. Geochemically, SiO2 range 73.9% 86.2%, Al2O3 (6.7%~17.1%), Fe2O3...

This paper discusses the principal domains of auto-and cross trispectra. It is shown that the cumulant and moment based trispectra are identical except on certain planes in trifrequency space. If these planes are avoided, their principal domains can be derived by considering the regions of symmetry of the fourth order spectral moment. The fourth order averaged periodogram will then serve as an ...

BACKGROUND The midline and paramedian mandibulotomy are surgical procedures that divide the mandibular bone into two halves and disconnects the condylar heads of the TMJ from each other. This study aimed to prospectively evaluate the temporomandibular joint (TMJ) functional and morphological changes after mandibulotomy using a reconstructed 3D models of the TMJ. METHODS Sixteen adult patients...

The Aravalli-Delhi Mobile Belt (ADMB) in the northwestern part of Indian Shield represents final stage a complex tectonic evolution witnessed by recognition three distinct orogenies that have resulted northwestward accretion terranes belonging to Archaean Neoproterozoic ages. In this contribution, review deformation structures different is discussed with their implications and global correlatio...

Background: HIV patients have several habits that can produce oral lesions. However, the association of oral habits and risk behaviors with oral and peri-oral lesions in HIV patients has not been studied in Ethiopia to date. Objective: To assess the relationship of oral and peri-oral lesions with oral habits, risk behaviors, socio-demographic factors and clinical stages of disease among HIV inf...

We present a set of formulae to extract the longitudinal deep inelastic structure function FL from the transverse structure function F2 and its derivative dF2/dlnQ 2 at small x. Our expressions are valid for any value of δ, being x the behavior of the parton densities at low x. Using F2 HERA data we obtain FL in the range 10 ≤ x ≤ 10 at Q = 20 GeV. Some other applications of the formulae are po...
