Aroma characterisation and retention after heat treatment and drying of fruits using extraction and GC-MS analysis

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

First Identification of Excited States in 59Zn

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.

Molecular Genetic Studies of the Blood Group ABO Locus in Man

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

Particle Interferometry in e+e- Annihilation

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

Burst Detection and Location in Pipelines and Pipe Networks - With Application in Water Distribution

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

Investigating genetic factors behind the decline of a threatened plant species – Tephroseris integrifolia (Asteraceae)

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

Internal Bremsstrahlung Accompanying the Positon Decay of 82Rb

The internal bremsstrahlung from the positon decay of 82Rb has been measured in the energy ranges 0.95-1.3 and 1.7-2.0 MeV. The measured intensity was about twice the value predicted by the charge-independent theory. The external bremsstrahlung produced in stopping the positons in Be, C and Al has been measured in the same energy intervals. Energies and intensities of the γ-rays from 82Rb have bee

Introductory Study of Variable Valve Actuation for Pneumatic Hybridization

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele

"Ur klumpig lera stiger skönhets vilja". Konflikten mellan ande och drift i Birger Sjöbergs *Konferensman"

Birger Sjöbergs dikt "KOnferensman" ur Kriser och kransar (1926) tolkas mot bakgrund av psykoanalytiska föreställningar, vilka Sjöberg sannolikt mött hos psykoanalytikern Poul Bjerre.Det som läker psykosen hos huvudpersonen är en estetiskt fattad teologi, där konst, drömmar och andra andliga produkter visar att drift och ande hör samman, inte bör fattas som dikotomiska eller antagonistiska krafter
