Hip fracture is the most serious and resource consuming consequence of osteoporosis. All patients need operation and hospital treatment which gives a great health economic impact. The two main types of hip fracture are cervical (femoral neck, intracapsular) and trochanteric (extra capsular). For the displaced cervical fractures the blood circulation to the femoral head is more or less damaged whic

The aim of the present study was to develop a method for generation of dimethylbenzylamine (DMBA) atmospheres in an exposure chamber and to investigate the possibility of using urinary DMBA metabolites for biological monitoring of exposure to DMBA. A DMBA atmosphere was generated by use of the gas-permeation principle. Six healthy male volunteers were exposed for 8 h to DMBA at air levels of 20, 4

Popular Abstract in Swedish Denna doktorsavhandling i ämnet pedagogik utgör en analys av effekter av den pågående kulturella globaliseringen genom att granska två internationella magisterprogram vid Lunds universitet. Studiens syfte är att spåra mönster i en bärande pedagogisk idé för överföring av ett interkulturellt tänkande i tvärkulturella möten genom att utforska, beskriva och försöka förstå The present study is designed to analyze the effects of the ongoing cultural globalization. It utilizes as its empirical setting two special programmes called the International Master's Programme (the IMP,) directed by Lund University in Sweden. The aim of the study is to infer a pedagogic idea for intercultural transmission through cross-cultural encounters by exploring, describing, and comprehen

For the purpose of this deactivation study, Pt- and vanadia supported catalysts were used. The catalysts have been exposed to aerosol particles of inorganic salts, with high- or low melting points. The average diameter of the generated salt particle was kept constant at around 70 nm. The aerosol particle penetration depth for the samples exposed to potassium salt, was 1 μm as measured by scanning

Infection with Vibrio cholerae is a significant problem in manydeveloping countries. Cultivation of Vibrio cholerae is used inproduction of CTB, which is a component in a cholera vaccine. Fed - batch cultivations with V. cholerae in defined mediahave been conducted and reproducible results were obtained. A probing feeding strategy developed by Åkessonfor E. coli cultivations has been tested.The pr

Objective-The neuropeptide substance P (SP) is an inducer of neurogenic inflammation and bone resorption in the middle ear. Resorption of the bone tissue structures surrounding the middle ear cavity is a distinct feature of the initial stage of acute otitis media (AOM), which may be due to nerve fiber release of SP. Material and Methods-To investigate possible release of SP in the middle ear mucos

In vitro tests are commonly employed to assess nebulizer performance. Whether the square or sine waveforms employed during in vitro tests could alter the nebulizer performance compared to that observed when a patient breathes through the nebulizer is debatable. Accordingly, the aim of this in vitro study was to compare the rates of delivery from nebulizers with simulated human breathing patterns t

Popular Abstract in Swedish De skånska godsen har genom århundradena inte bara utgjort ett spektakulärt inslag i landskapsbilden, de har också varit centrum för politisk maktutövning och jurisdiktion. I denna bok kartläggs och analyseras de skånska godsens ekonomiska och arbetsorganisatoriska utveckling från dansk tid till 1800-talets andra hälft. Utvecklingen vid nio gods uppmärksammas i fallstudThe aim of this study is to systematically survey and analyse the Scanian manors’ economic and labour organisational development from the province’s Danish times to the middle of the nineteenth century. In this thesis the various surveys provides some clear results that make it possible to generalise the Scanian estate development. Manors were generally large at the end of the the seventeenth cent

The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics. A testing arrangement is presented with which the comp

Two new vectors are described, the expression vector pB3 PGK and the CRE recombinase vector pCRE3. The pB3 PGK has a zeocin-selectable marker flanked by loxP sequences and an expression cassette consisting of the strong PGK1 promoter and the GCY1 terminator. The S. cerevisiae genes RKI1, RPE1, TAL1 and TKL1 were cloned in pB3 PGK and integrated in the locus of the respective gene, resulting in ove

Free volume and density gradient widths of the free surface of high molecular mass polystyrene was characterized by use of a pulsed low-energy positron lifetime beam. A density gradient in terms of mass density (g/cm(3)) versus depth (nm) was obtained from the experimental beam data using a novel approach, yielding a width of the density gradient of approximately 3.5 nm. The procedure accounted fo

In this paper we apply a microscopic nonequilibrium many body Keldysh Green's functions approach to an analysis of complex intersubband optical materials and devices. The calculated absorption/gain spectra are in very good agreement with transmission spectroscopy measurements of quantum cascade laser structures operating in the mid-infrared (midIR). The very good agreement reached between theoreti

The yrast superdeformed band in Zn-61 has been established using Si-28(Ar-36, 2pn)Zn-61 and Ca-40(Si-29, 2 alpha)Zn-61 fusion-evaporation reactions. The excitation energy of this band was determined via two transitions that link this band to the normally deformed states. Lifetime analysis of this band resulted in a quadrupole moment of Q(t) = 3.0 +/- (0.5)(0.4)e b, which corresponds to a deformati
