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

Popular Abstract in Swedish Protonen, neutronen och elektronen utgör de grundläggande byggstenarna för materian i vårt universum. Emedan elektronen, som tillhör den grupp av partiklar som kallas leptoner, är "odelbar", är protonen och neutronen, som tillhör gruppen hadroner, i sin tur uppbyggda av mindre partiklar, kvarkar och gluoner (partoner). En elektron växelverkar med andra partiklar genom sThe 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, 1.735 < etajet3.5 GeV) are found i

Regulation of Islet Function by the Neuropeptide PACAP

Popular Abstract in Swedish Omkring 2% av världens befolkning lider i dag av folksjukdomen diabetes och siffran ökar ständigt. Trots behandling får många diabetespatienter komplikationer av sin sjukdom, såsom fotsår, nedsatt syn, känselbortfall, njursvikt, kärlkramp och hjärtinfarkt. Halten av insulin i blodet spelar en viktig roll vid uppkomsten av diabetes. Insulinet produceras i bukspottkörtelnIt is known that parasympathetic, sympathetic and sensory nerves innervate the islets and that these nerves harbor both classical neurotransmitters and neuropeptides. However, the neural influence on islet hormone release is complex and not yet fully understood A recently discovered pancreatic neuropeptide is pituitary adenylate cyclase-activating polypeptide (PACAP). The aim of this thesis was to

Acoustofluidic rare cell sample preparation

Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. Rare cells are within this thesis defined as cells that are present in numbers of 1-1000 per mL in a much
