I review the various methods for taking account of finite quark masses in DIS and related processes. I pay particular attention to the so-called variable flavour number schemes (VFNS) which are designed to extrapolate smoothly from the region near threshold of production of heavy quark pairs to the region where the quarks become effectively massless. Plenary talk given at 3rd UK Phenomenology W...

We summarize the experimental and theoretical results presented in the " Physics at the Highest Q 2 and p 2 t " working group at the DIS 2000 Workshop. High Q 2 and p 2 t processes measured at current and future colliders allow to improve our knowledge of Standard Model (SM) physics, by providing precise measurements of the SM parameters and, consequently, consistency checks of the SM. Moreover...

A personal selection is made of some of the hot topics debated at this conference, including examples of using our knowledge of QCD to make electroweak measurements, structure functions at low x in the light of the corrections to the leading BFKL behaviour recently calculated, diffraction, the existence of one or more Pomerons and whether it/they may have a well-defined structure function, some...

We calculate the cross section for q ¯ qg-production in diffractive DIS with finite fermion masses and zero momentum transfer. The calculation is done in the leading log(1/x P) approximation and is valid for the region of high diffractive masses (small β). We apply our cross section formula to diffractive charm production at HERA: in a Monte-Carlo-Simulation of diffractive D * ± meson productio...

Web based instruction is growing at an incredible rate. Teachers, instructors, trainers and several others are putting their instructional content online. The format, style and media types vary from instructor to instructor. In essence web based instruction is being done by an unknown number of people in an unknown number ways using different media types and platforms. In this paper, an instruc...

Deep inspirations (DIs) taken before an inhaled challenge with a spasmogen limit airway responsiveness in nonasthmatic subjects. This phenomenon is called bronchoprotection and is severely impaired in asthmatic subjects. The ability of DIs to prevent a decrease in forced expiratory volume in 1 s (FEV1) was initially attributed to inhibition of airway narrowing. However, DIs taken before methach...

a case with two simultaneous dens invaginations (dis) and one dens evagination (de) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. de known as talon cusp of the anterior teeth is a rare entity and its co-existence with di has been reported scarcely in the literature. simultaneous occurrence of two dis with one de has not been reported elsewhere. u...

We explain microscopically why split attractor flows, known to underlie certain stationary BPS solutions of four dimensional N = 2 supergravity, are the relevant data to describe wrapped D-branes in Calabi-Yau compactifcations of type II string theory. We work entirely in the context of the classical geometry of A-branes, i.e. special Lagrangian submanifolds, avoiding both the use of homologica...

the present study on politeness is an attempt to examine (dis)agreeing strategies utilized by efl learners while chatting on the internet. subjects of the study were forty male and thirty-three female iranian natives whose internet relay chat (irc) interactions, composed of 400 excerpts, were collected between december 2007 and september 2008. data analysis was based on the general taxonomy of ...

We determined the dose-response curves to inhaled methacholine (MCh) in 16 asthmatic and 8 healthy subjects with prohibition of deep inhalations (DIs) and with 5 DIs taken after each MCh dose. Flow was measured on partial expiratory flow-volume curves at an absolute lung volume (plethysmographically determined) equal to 25% of control forced vital capacity (FVC). Airway inflammation was assesse...
