The flagellate Euglena gracilis shows rhythms in phototaxis and cell shape changes between oblong and round. Artificial UV-B radiation of 0.5 W m-2 caused a loss in phototaxis, but the peak of activity occurred at the same time as for control cells. The transition from round to oblong cell shape was slower after UV-B radiation, but the amplitude between the roundest and the most oblong cell shape
The temperature distribution in a concrete structure varies due to complex interactions with the surrounding climate. Solar radiation, air temperature, wind speed and long-wave radiation all affect the temperature in the material, and may cause movements in the longitudinal and transversal directions. If these movements are restrained, stresses and strains can be induced which may contribute to cr
This study, addressing the analysis of pitch patterns in Estonian Swedish compounds, enables us to draw some preliminary conclusions about the characteristics of accentuation in this little studied regional variety of Swedish. The analysis in the first part of the paper was inspired by the classification of Edvin Lagman (1979) who on the basis of auditory analysis distinguished between four accent

Popular Abstract in English Fruits are a key complement to the diet of many people in the southern region of Africa, especially in rural areas. maphilwa (Vangueria infausta L.), maçanica (Ziziphus mauritiana), maçala (Strychnos spinosa), mapsincha (Salacia kraussi), cajú (Anacardium accidentale L.), mavungwa (Landolpia kirki) are some of the most commonly found fruits in sub-Saharan Africa, particThis study concerns the identification and characterisation of volatile components of fruits, and evaluation of the effect of heat treatment and drying on retention or loss of volatiles of fruits. The investigation included developing a procedure to extract volatile components from the fruit matrix, a purification step, separation, identification and quantification. Initial experiments with Vangue
Excited states in 59Zn were observed for the first time following the fusion-evaporation reaction 24Mg + 40Ca at a beam energy of 60 MeV. The GASP array in conjunction with the ISIS Silicon ball and the NeutronRing allowed for the detection of n-rays in coincidence with evaporated light particles. The mirror symmetry of 59Zn and 59Cu is discussed.
Popular Abstract in Swedish Blodgruppering med genteknik - studier av ABO-systemets arvsanlag Populärvetenskaplig sammanfattning på svenska Blodtransfusioner som utfördes före sekelskiftet slutade ofta med svåra komplikationer och i många fall patientens död. Scenariot förändrades dramatiskt till det bättre i och med den österrikiske läkaren Karl Landsteiners upptäckt av blodgruppssystemet ABO (The ABO blood group system is undoubtedly the most important genetic and phenotypic marker in clinical transfusion medicine. The A and B determinants are immunodominant, terminally located carbohydrate residues of glycoconjugates on erythrocytes and other cell surfaces. The enzymes responsible for assembly of these structures are glycosyltransferases encoded by the ABO genes on chromosome nine. T
This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. Since the Jetset event generator and its implementation of the Bose-Einstein correlation effect, LUBOEI, is the most used tool in the particle physics commun
Sudden pipe bursts occur in high-pressure water transmission pipelines and water distribution networks. The consequences of these bursts can be very expensive due to the outage time while the burst pipe is repaired, the cost of repair, and damage to surrounding property and infrastructure. As a result, it is advantageous to minimise the detection and location time after the burst occurs. Currently
Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. A census of extant populations from 1980 to 2009 revealed a dramatic decrease in population sizes during the early 1990s, despite far-reaching conservation measures. Knowledge of causes of species decline is n
