  2. 1. Forward Jet Production in ep-collisions at HERA

    Author : Albert Knutsson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forward Jets; Parton dynamics; Jets; Small-x; Low-x; Elementary particle physics; QCD; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2007:Knutsson;

    Abstract : The production of forward jets has been measured in deep inelastic $ep$ collisions at HERA. The results are presented in terms of single differential cross sections as a function of the Bjorken scaling variable ($x_{Bj}$) and as triple differential cross sections $d^3 sigma / dx_{Bj}dQ^2dp_{t,jet}^2$, where $Q^2$ is the four momentum transfer squared and $p_{t,jet}^2$ is the squared transverse momentum of the forward jet.

  4. 2. Natural and induced immunity against the tumour-associated antigen, Ep-CAM

    Author : Szilvia Mosolits; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Tumour immunology; Ep-CAM; anti-idiotypic antibodies; vaccination;

    Abstract : The tumour-associated antigen (TAA), Ep-CAM is overexpressed on various human carcinomas, including colorectal carcinoma (CRC). TAAs or their immunodominant epitopes that are spontaneously recognised by the immune system might constitute a suitable target for immunotherapy. READ MORE

  5. 3. A Farewell to Arms : Motivational Change and Divergence Inside FARC-EP 2002-2010

    Author : Michael Jonsson; Stefano Guzzini; Svante Cornell; Maria Heimer; Stathis Kalyvas; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Civil war; motives; motivational change; Colombia; mid-level commanders; political economy of conflict; FARC; insurgency; defections; Statskunskap; Political Science;

    Abstract : How can motivational change and divergence inside a rebel group be explained and what does this imply for our understanding of civil wars? In contemporary research, these questions have received limited attention. In many studies, motives are either overlooked, inferred from a single type of motive indicator or assumed to be narrow, static over time and homogenous throughout the organization. READ MORE

  6. 4. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction

    Author : Martin Karlsson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; H1; jets; forward jet; small-x; parton dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2002:Karlsson;

    Abstract : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. READ MORE

  7. 5. Prostaglandin E2 in Brain-mediated Illness Responses

    Author : Louise Elander; Anders Blomqvist; Marianne Schultzberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostaglandin e2; PGE2; cox-1; cox-2; mPGES-1; fever; anorexia; food intake; HPA-axis; EP-receptor; LPS; IL-1; IL-6; MEDICINE; MEDICIN; Neurobiology; Neurobiologi;

    Abstract : We are unceasingly exposed to potentially harmful microorganisms. The battle against threatening infectious agents includes activation of both the innate and of the adaptive immune systems. READ MORE
