The Lund SSAMS machine has been in routine operation since 2004. We present results from the last year of operation of the facility. The reference sample IAEA C7 and the "old" oxalic acid, Oxl, were used as secondary standards. As primary standard for calculations the OxII was used. The background and long term stability of the facility are discussed. We also report on the quality of the C-13/C-12

The number of species in the Pegomya maculata species group is raised from three to four with the description of a new, Holarctic species, P. grahami sp. nov. The other species, P. maculata Stein, P. atricauda Ringdahl and P. macrophthalma Griffiths, are redescribed. The number of species in Europe is raised from two to four. Two species, P. grahami (previously recorded as P. maculata) and P. macr

The striatum is the main input nucleus of the basal ganglia. Striatal subregions, which play different roles in motor functions, receive inputs from different cortical regions. Regulation of synaptic plasticity at the level of corticostriatal synapses is believed to underlie habit formation and motor learning. Alteration of plasticity at the level of corticostriatal synapses has been associated wi

Background: Variation in the incidence, survival rate and factors associated with survival after cardiac arrest in Europe is reported. Some studies have tried to fill the knowledge gap regarding the epidemiology of out-of-hospital cardiac arrest in Europe but were unable to identify reasons for the reported differences. Therefore, the purpose of this study was to describe European Emergency Medica

Halisaurine mosasaurs are poorly known, represented by a small number of specimens from the Santonian-Maastrichtian (similar to 86 Ma - similar to 66 Ma), but enjoyed broad palaeobiogeographic distribution during that time. They are important for understanding mosasaur evolution because certain aspects of their morphology retain the relatively plesiomorphic or minimally modified squamate condition

Global gene expression analysis has been a major tool for urothelial carcinoma subtype discovery. This approach has revealed extensive complexity both in intrinsic features of the tumor cells and in the microenvironment. However, global gene expression cannot distinguish between gene expression signals originating from the tumor cells proper and from normal cells in the biopsy. Here, we use a larg

Two novel Chlamydomonas-like species, belonging to the Moewusii clade, have been de-scribed. The first species inhabits eutrophic and neutral to basic pH waters in Sweden and England. It is easily recognizable under a light microscope due to its morphology (a small green prolate spheroidal shape with a large and truncated papilla at its anterior end, two equal flagella, a single lateral eyespot, a

We investigate the second-order von Neumann approach from a diagrammatic point of view and demonstrate its equivalence with the resonant tunneling approximation. The investigation of higher order diagrams shows that the method correctly reproduces the equation of motion for the single-particle reduced density matrix of an arbitrary non-interacting many-body system. This explains why the method rep

The European species of Foersterella Dalla Torre 1897 (Hymenoptera: Tetracampidae) are treated, including two previ-ously described species, F. erdoesi Bouček and F. reptans (Nees), and two new species, F. angusticornis sp. nov. and F. fuscicornis sp. nov. Morphological concepts of the species are based mainly on characters in the male antenna, which fe-males lack, and with the exception of F. erd

DNA barcoding (molecular characterisation) is a useful tool for describing the taxonomy and systematics of organisms. Over 250 species of avian haemosporidian parasites have been described using morphological characters, yet molecular techniques based on polymerase chain reaction (PCR) suggest this diversity is underestimated. Moreover, molecular techniques are particularly useful for the detectio

Uppsatsen undersöker cyberoperationer inom jus ad bellum-regimen, där reglerna återfinns främst uttryckta i FN-stadgan. Inom ramen för arbetet är cyberoperationer försök att ändra, störa eller förstöra datorsystem eller nätverk, alternativt information eller program på dessa, med ett politiskt intresse eller säkerhetsintresse. Användning av traditionella vapen exkluderas från definitionen. FrågesThis thesis explores cyber operations under the jus ad bellum-regime, where the rules primarily are expressed in the UN Charter. Cyber operations are for the purpose of this thesis understood as attempts to change, disrupt, or destroy computer systems or networks, alternatively, programs or information on them, whilst having a political or security interest. The use of traditional weapons is exclu

The thermionic RF gun using a BaO cathode at the MAX-lab linac injector has been successfully commissioned for additional operation as a photocathode gun. By retaining the BaO cathode, lowering the temperature below thermal emission and illuminating it with a UV (263 nm) 9 ps laser pulse a reduced emittance and enhanced emission control has been achieved. Measurements show a normalised emittance o

Energy is the essential requirement of humans. It plays a major role in the development of any country. The present status of crude oil import of India in the financial year 2018-19 was around 22,64,98,000 MT of Rs. 7,83,183 crore and other fuels like LPG, MS, Naphtha, ATF, etc. were around 3,33,48,000 MT of Rs. 1,13,665 crore [1] and the total installed capacity of India is around 3,65,981.00 MW

Fuel economy and emissions are the two central parameters in heavy duty engines; most of the existing heavy duty engines are run with diesel. The overall efficiency of diesel engines is good however they suffer from high levels of emissions mainly NOX and soot. Using alternative fuels like Natural-Gas has shown to be a good way to reduce emissions level. Diesel engines can be easily converted to N
