A technique to determine which nutrients limit bacterial growth in soil was developed. The method was based on measuring the thymidine incorporation rate of bacteria after the addition of C, N, and P in different combinations to soil samples. First, the thymidine incorporation method was tested in two different soils: an agricultural soil and a forest humus soil. Carbon (as glucose) was found to b
Something has happened in the field of Service Studies. With the introduction of what has been called Service Dominant Logic a large proportion of the established theories related to service as a phenomenon has been challenged. From previously having been defined as something different from the tangible things we buy (goods); i.e. a residual, service defined out of what service is not, the new lin
In this paper, the critical factors behind commercialization of new product development (NPD) are investigated in order to add to our understanding of what drives and hampers the commercialization of new products and services. With the illustration of nine cases of commercialization from three multinational organizations, an initial framework of three categories of factors related to the success o
This paper seeks to discuss the nature of complex relationships among participants in organizational life, including ways in which paradox and ambiguity in their interactions impact upon organizational performance. Any relationship emerges and subsists through interaction between people. The nature of a relationship is the result of double description (Bateson, 2002). Each of the parties involved
Over 20?000 MR systems are currently installed worldwide and, although the majority operate at magnetic fields of 1.5?T and below (i.e. about 70%), experience with 3-T (in high-field clinical diagnostic imaging and research) and 7-T (research only) human MR scanners points to a future in functional and metabolic MR diagnostics. Complementary to previous studies, this review attempts to provide an
Organohalogen compounds constitute one of the important groups of persistent organic pollutants (POPs). Among them, due to their long-term health effects, one should pay attention on organochlorine pesticides, polychlorinated biphenyls (PCBs) and perfluoroalkylated substances (PFASs). This paper is an attempt to answer the question about relation between the fact of cohabitation by couples expecti
Accurate accelerator mass spectrometry (AMS) measurements rely on standards with well-known isotopic ratios. For radiocarbon measurements, a number of standards with different properties are commercially available, of which the IAEA-C6 sucrose standard with a 14C value of 150.61 pMC is the most active. When analyzing biological samples resulting from studies using 14C-labeled substances, the activ
We analyze the Ce3+-Pr3+:Y2SiO5 emission spectra obtained under selective excitation of the two Ce3+ sites in Y2SiO5 and we show clear evidence of direct energy transfer from Ce3+ to Pr3+. Energy transfer microparameters were calculated from the experimental spectral overlap between the Ce3+ emission and the Pr3+ and Eu3+ absorptions from which, the transfer mechanisms Ce3+-> Pr3+ are concluded to
The Xenopus oocyte and the Human Embryonic Kidney (HEK) 293 cell expression systems are frequently used for functional characterization (deorphanization) of insect odorant receptors (ORs). However, the inherent characteristics of these heterologous systems differ in several aspects, which raises the question of whether the two systems provide comparable results, and how well the results correspond
We used remote sensing, geographical information systems, Google Earth™ images, and regional geology in order to (i) improve the mapping of linear structures and understand the chronology of different mafic dyke swarms in the Ahmeyim area that belongs to the Archean Tasiast-Tijirit Terrane of the Reguibat Shield, West African craton, NW Mauritania. The spatial and temporal distributions with the t
Endosymbiotic organelles of eukaryotic cells, the plastids, including chloroplasts and mitochondria, are highly integrated into cellular signalling networks. In both heterotrophic and autotrophic organisms, plastids and/or mitochondria require extensive organelle-to-nucleus communication in order to establish a coordinated expression of their own genomes with the nuclear genome, which encodes the
There is no alternative! Margaret Thatcher once proclaimed in order to defend neoliberalist reforms and – implicitly – the capitalist regime. But if one doesn’t agree with Thatcher’s definition of the situation and her (and her many followers’) subsequent analysis, what viable options does one really have? Is it possible to come up with an empirically grounded alternative to the dominant modes of
Problem discussion: To be more competitive, Trading Area Wood is working on developing their suppliers in efficiency projects. However, they find it hard to motivate their suppliers to take part in the projects. Therefore, they need a way to show the suppliers the positive effects of participating in the efficiency projects. Moreover, Trading Area Wood has troubles to predict the economical outcom
Hälften av Afrikas befolkning - mer än 300 miljoner människor - hotas idag av markförstöring och ökenspridning. De flesta forskare är överens om att markförstöring orsakas av mänsklig aktivitet som avsiktligt eller oavsiktligt rubbar balansen i redan känsliga ekosystem. Namibia det torraste landet söder om Sahara, vilket följaktligen gjort att landet är mycket utsatt för ökenspridning och markförsHalf of Africa’s population - more than 300 million people - is threatened by land degradation. In general, land degradation is initiated when people intentionally or accidentally disturb the balance in a already fragile ecosystem. Poor management practices such as overgrazing, puts pressure on land already close to exceed the limits of sustainability. Besides suffering from overgrazing issues, Na
This work has been done for Tetra Pak Distribution (TPD) at the Department of Engineering Logistic at the Lund Institute of Technology. My task was mainly to create a set of simulation models based on the Tetra Pak Distribution Lines. These models are going to be used by TPD to try to analyse the effect of the accumulation systems on the line efficiency. The inputs for the models are failure rate
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusi
In a previous 16-month seasonal study on living (stained) benthic foraminifera from two fjords on the Swedish west coast, it was reported that foraminifera proliferated in response to phytodetritus input; the strongest response came from the opportunistic species Stainforthia fusiformis. In this study, our objective was to find out if that phytodetritus input resulted in a change in the carbon iso
Dynamic glucose-enhanced (DGE) imaging uses chemical exchange saturation transfer magnetic resonance imaging to retrieve information about the microcirculation using infusion of a natural sugar (D-glucose). However, this new approach is not yet well understood with respect to the dynamic tissue response. DGE time curves for arteries, normal brain tissue, and cerebrospinal fluid (CSF) were analyzed
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressive disabling condition, for which tobacco smoking, environmental pollution, inherited alpha-antitrypsin deficiency and their interactions are predisposing factors. We carried out a family study on COPD in order to address the role of heritable and environmental risk factors at a population level.METHODS: In a nationwide study o
The main purpose with this Master's thesis has been to through a case study investigate and analyze the music library activity at the Public Library in Lund, in order to find out according to which ideas and principals this activity is run by. It also discusses how you at the music department handle your task as intermediary of music and how well this coincides with the users expectations. To
