A search for gravitinos produced in e(+/-)p collisions is performed using the H1 detector at HERA. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of 64.3 pb(-1) for e(+)p collisions and 13.5 pb(-1) for e(-)p collisions. If R-parity is not conserved, the t-channel exchange of a selectron can produce a neutralino, which, in models where the gravi
Since the discovery of neuropeptide Y which is co-stored and co-operate with noradrenaline (NA) in sympathetic nerve fibers, several scientific groups have searched for structures with neuropeptide Y antagonistic properties. Research has mainly focused on various peptide fragments which originate from or are related to the neuropeptide Y sequence. Some non-peptide antagonists have been proposed bu
Small-x evolution in QCD is conveniently described by Mueller's dipole model which, however, does not include saturation effects in a way consistent with boost invariance. In this paper we first show that the recently studied zero and one dimensional toy models exhibiting saturation and explicit boost invariance can be interpreted in terms positive definite k-> k+1 dipole vertices. Such k-> k+1 ve
A search is reported for Higgs boson decay to mu(+)mu(-) using data with an integrated luminosity of 24.8 fb(-1) collected with the ATLAS detector in pp collisions at root s = 7 and 8 TeV at the CERN Large Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120-150 GeV search range. For a Higgs boson with a mass o
This Letter presents a search for a hidden-beauty counterpart of the X(3872) in the mass ranges of 10.05-10.31 GeV and 10.40-11.00 GeV, in the channel X-b -> pi(+)pi(-)gamma(1S)(-> mu(+)mu(-)), using 16.2 fb(-1) of root s = 8 TeV pp collision data collected by the ATLAS detector at the LHC. No evidence for new narrow states is found, and upper limits are set on the product of the Xb cross section
This Letter presents a search for magnetic monopoles with the ATLAS detector at the CERN Large Hadron Collider using an integrated luminosity of 2.0 fb(-1) of pp collisions recorded at a center-of-mass energy root s = 7 TeV. No event is found in the signal region, leading to an upper limit on the production cross section at 95% confidence level of 1.6/epsilon fb for Dirac magnetic monopoles with t
Applying contemporary ideas regarding the role literature may have had in human evolutionary history to literary analysis, using Herman Melville's Moby Dick as a case study. The paper focuses on the function of male bonding in the text, the ways in which the setting is defined by humanity's evolutionary past, and the artistic function of the hunt, as it is described in the text.
The thesis deals with matters relating to neglected diseases and the lack of pharmaceutical R&D for the same diseases. Everybody is entitled to the right to health and subsequently the right to access to medicines, however not everyone has been receiving the benefits of this right. Currently there is an unsatisfying market-driven system, that can be changed by new and innovative approaches, su
Breast cancer is the major cause of deaths related to cancer for women worldwide. Although much is known about this malignancy, extensive research is still needed to gain complete understanding of the complexity of the disease. The inter and intra tumor heterogeneity is an important trait of breast cancer. The intratumor heterogeneity is reflected in sub-populations of cancer cells that appear to Breast cancer is the major cause of deaths related to cancer for women worldwide.

Standard Model events with prompt, isolated, same-charge high-pT leptons are rare, and therefore events with such final states provide a powerful signature towards new discoveries. This thesis presents two searches for doubly charged Higgs bosons decaying into same-charge lepton pairs using proton–proton collision data recorded by the ATLAS detector at the LHC. Observation of doubly charged Higgs
A search for the production of single top-quarks via flavour-changing neutral-currents is presented. Data collected with the ATLAS detector at a centre-of-mass energy of root s = 7 TeV, corresponding to an integrated luminosity of 2.05 fb(-1), are used. Candidate events with a semileptonic top-quark decay signature are classified as signal- or background-like events by using several kinematic vari
Upper limits on direct photon production were determined as a function of the transverse momentum for 0.7 < pT ≤ 3.2 GeV/c with the WA98 experiment in p + C and p + Pb collisions at . The results are compared to direct photon measurements in Pb + Pb collisions at by WA98. Implications for a possible thermal direct photon contribution are discussed.
Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb(-1)
A search is made for massive highly ionising particles with lifetimes in excess of 100 ns, with the ATLAS experiment at the Large Hadron Collider, using 3.1 pb(-1) of pp collision data taken at root s = 7 TeV. The signature of energy loss in the ATLAS inner detector and electromagnetic calorimeter is used. No such particles are found and limits on the production cross section for electric charges
This work is aimed at presenting a design for the proposed HIBEAM beamline which seeks to perform neutron oscillation measurements at the European Spallation Source (ESS). The design is informed by beamline simulations performed with PHITS 3.33 and detector simulations performed with both PHITS and Geant4 11.2. The shielding, consisting of 45 cm of steel and 85 cm of heavy concrete at its thickest
Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr
In the last decades, scholars, managers and consultants have shown increased interest in identifying the characteristics of high-performance organizations. Searching for ways to improve organizational performance and respond to a growing demand for quality products and services in a rapidly changing environment, this subject is of special interest of managers in both public and private organizatio
Marketing research has acknowledged the concept of authenticity. It is argued that consumers in modern society increasingly search for something real, in contrast to what they perceive as mediated and distorted. Producers of regional food brands has acknowledged this trend, and started to market their products as being authentic. Given the potential practical and theoretical contributions in study
