    In high centre-of-mass energy lepton-nucleon collisions the space-time time resolution of partonic processes can be {\it fine-tuned} within a dynamical range which is unattainable in hadronic collisions. Replacing nucleons by nuclei of variable atomic number enables one to tune the strength of colour forces. The experimental program of high energy electron-nucleon and its extension to electron-nucleus collisions should thus give an unique opportunity to experimentally explore the transition between the soft and hard interactions of small and extended partonic systems. Such an experimental program, which can be realized at DESY and/or BNL with relatively modest cost, is discussed in this talk.Comment: Plenary talk at the PANIC conference, Uppsala, June 1999. 8 pages. 3 figure

    Zambia Country Profile: Promoting the Employability and Employment of People with Disabilities Through Effective Legislation (Southern Africa)

    Get PDF
    In recent years, many countries have adopted policies aiming to promote the rights of people with disabilities to full and equal participation in society. In Africa, some countries have made progress in introducing disability-related legislation, but many of these laws have not yet been implemented, and in others, existing national laws need to be reviewed in order to achieve equalization of opportunities for persons with disabilities. The country study for Zambia is part of an ILO project, “Promoting the employability and employment of people with disabilities through effective legislation”. The first phase of the programme (2001-2004) aimed at enhancing the capacity of national governments in selected countries of East Africa and Asia1 to implement effective legislation concerning the employment of people with disabilities. Phase 2 of the project (2004-2007) is extending coverage to several additional countries (Lesotho, Malawi, South Africa and Zambia in Africa and Viet Nam in Asia), with a broadened focus on provisions for vocational training and skills development. This country study outlines the main provisions of the laws and policies in place in Zambia concerning the employment and training of people with disabilities. An initial review of the implementation of the legislation is also provided. A concluding comment underlines the progress made in the country and points to areas that have been identified, by key stakeholders or in the literature, as in need of further improvement. It may be read in conjunction with the regional overview prepared for the Technical Consultation in 2002, “Employment of people with disabilities - The impact of legislation (East Africa),Technical Consultation Report, Addis Ababa, 20-22 May 2002”, ILO, 2002

    Bounds on QCD Instantons from HERA

    Full text link
    Signals for processes induced by QCD instantons are searched for in HERA data on the hadronic final state in deep-inelastic scattering. The maximally allowed fraction of instanton induced events is found at 95% confidence level to be on the percent level in the kinematic domain 0.0001<x<0.01 and 5 < Q-squared < 100 GeV-squared. The most stringent limits are obtained from the multiplicity distributions.Comment: 14 pages, latex, 9 figures as ps/ep

    Description of elastic vectormeson production and F_2 by two pomerons

    Using the Model of the Stochastic Vacuum many diffractive processes have been calculated by investigating the dipole-dipole scattering at a cm-energy of 20 GeV. In this work we extend the calculation to larger energies and small dipoles. We assume that there are two pomerons, the hard- and the soft-pomeron, which cause the different energy dependence for processes dominated by small or large dipoles. The physical processes are obtained by smearing the dipole-dipole amplitude with wavefunctions. For small dipoles the leading perturbative contribution is taken into account. By that way we can describe in addition to the already calculated low energy results (20 GeV) also the HERA data for the considered processes in nearly the whole energy and Q^2 range.Comment: LaTeX2e, 4pp, espcrc2mod.sty (appended, espcrc2 with corrected error), graphicx.sty, 17 eps-figures.

    According to the witness statements and the physical observation of the accident point, the accident happened while the de-miner was walking from the rest area to his clearance lane. He stepped on missed PMN anti-personnel mine in cleared area. Therefore, this mine was missed during the clearance operation. The exploded mine resulted in below knee amputation of deminer’s right leg, multiple injuries on his left leg, left foot heel, right hand palm and some minor injuries on his right arm. The de-miner was sent to Khost hospital after receiving first aids in the site. While accident happened the de-miner did not have PPE on, he was walking in cleared area to proceed to his clearance lane after the break time
