Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.
In market-driven requirements engineering for platform-based development of embedded systems such as mobile phones, it is crucial to market success to find the right balance among competing quality aspects (aka nonfunctional requirements). This paper presents a conceptual model that incorporates quality as a dimension in addition to the cost and value dimensions used in prioritisation approaches f
Various papers described mesh morphing techniques for computational biomechanics, but none of them provided a quantitative assessment of generality, robustness, automation, and accuracy in predicting strains. This study aims to quantitatively evaluate the performance of a novel mesh-morphing algorithm. A mesh-morphing algorithm based on radial-basis functions and on manual selection of correspondi
Popular Abstract in Swedish Framtida klimatförändringar påverkas till stor del på människans utsläpp av CO2, samt av klimat- och CO2-relaterade återkopplingar genom kolcykeln i både landbaserade ekosystem och hav. Landbaserade ekosystem tar för tillfället upp omkring 25% av de antropogena utsläppen av CO2 från förbränning av fossila bränslen och markanvändning, men att tillskriva vilka mekanismer The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it
This thesis is based upon four original papers describing the characterisation of mantle cell lymphoma (MCL) tumours and cell lines in comparison with different populations of normal B cells. Gene expression profiling, which were used in the studies, has during recent years developed as an important tool in characterisation of different types of malignancies. In this thesis, the technique is used
Modern military multi-role combat aircrafts need an emergency power system (EPU) to maintain back-up power supply for all normal and degraded flight modes. The reason for this requirement is that modern combat aircrafts are designed with built-in relaxed or negative stability. Inability of the Flight Control System to perform continuous, corrective control surface actuation, due to loss of power
We have investigated nuclear fragmentation reactions of a relativistic Pb-208 beam. Ten isomeric states for nuclei with A = 142-152 and Z = 62-67 were observed. Measured isomeric ratios were compared, together with values from other experiments, with prediction of theoretical models. The discrepancies between the experimental and theoretical values were discussed in terms of transitions by-passing
Purpose - Even though noticeable improvements have been made in global health in recent years, the distribution is uneven throughout the world and many developing and low-income countries lack access to required medicine and vaccines. Thus, a model to strategically source vaccines for these nations can contribute a great deal. This paper presents an extensive review of strategic sourcing literatur
We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5 fb(-1) of root s = 7 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with a
Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
Background: Local recurrence is a major factor affecting survival after treatment for head and neck squamous cell carcinoma (HNSCC). It is possible that the normal processes involved in wound healing after surgical removal of a primary tumor can boost the regrowth of residual cancer cells, thereby contributing to the recurrent growth. In this work, we collected human wound fluids and used them to
Diabetes mellitus is one of the most common endocrine disorders in dogs and is commonly proposed to be of autoimmune origin. Although the clinical presentation of human type 1 diabetes (T1D) and canine diabetes are similar, the aetiologies may differ. The aim of this study was to investigate if autoimmune aetiology resembling human T1D is as prevalent in dogs as previously reported.
Africa is an important part of the global carbon cycle. It is also a continent facing potential problems due to increasing resource demand in combination with climate change-induced changes in resource supply. Quantifying the pools and fluxes constituting the terrestrial African carbon cycle is a challenge, because of uncertainties in meteorological driver data, lack of validation data, and potent
Cannulation of the papilla vateri represents an enigmatic first step in endoscopic retrograde cholangiopancreaticography (ERCP). In light of falling numbers of (diagnostic) ERCP and novel techniques, e. g. short-wire system, we were interested in the approach novice and experienced endoscopist are taking; especially, what makes a papilla difficult to cannulate and how to approach this. We devised
A bench-scale unit for the development of an enzymatic process for the bioconversion of lignocellulosics to ethanol has been used to study the recycling of waste-water streams to minimize fresh-water requirements and reduce effluent streams. Willow, after impregnation with sulphur dioxide, was steam-pretreated, enzymatically hydrolysed, and the sugars produced were fermented using S. cerevisiae. T
A gas chromatographic procedure was developed to determine the relative amounts of D- and L-arabinitol in urine. Samples were filtered, diluted, purified through extractions, evaporated, and treated with trifluoroacetic anhydride; the arabinitol derivatives thus obtained were separated on a chiral stationary phase and registered by using an electron-capture detector. Urine samples from a patient w
