Damaged or partially damaged pumps can cause issues that at best is an inconvenience and at worst a catastrophe. In order to prevent such issues it is necessary to catch any potential damage as early as possible. One possible solution is to use a sensor that can be placed on or near a pump in order to monitor it using audio. Audio based fault detection is still a relatively new field of research,
Turbulent emulsification devices are used in many applications of chemical engineering. There is large need to predict the drop sizes resulting from such devices, for example in the context of designing new devices, modifying current design, or adapting designs to new products. The Kolmogorov-Hinze framework is the most used approach, much due to its simplicity and flexibility. However, there is n
This thesis examines how Yumna Al-Arashi’s Aisha negotiates the tension between the potential for empowerment and the risk of exoticization in its photographic representation of tattooed women. Aisha is a photobook and artist’s book that combines portraits, landscapes, archival family photographs, and written fragments. It begins from the absence of Al-Arashi’s greatgrandmother’s facial tattoo in
Political discourse has been and remains a central topic of scholarly inquiry due to its role in shaping public opinion, ideologies, and social interactions. It constitutes a highly polysemiotic form of communication in which hand expressions play a central role in the organisation and interpretation of interactions. This thesis investigates hand expressions in televised political discourse from

It has been a common practice both in Sweden and worldwide to enclose nuclear reactors with prestressed concrete structures. The prestress level decreases with time from its initial value due to various degradation mechanisms. To ensure that the prestress level is sufficient the tendon force is measured at regular in-service inspections. The intention with this paper is to present a reliability-ba
Addition of surfactants to aqueous solutions of polyelectrolytes carrying an opposite charge causes the spontaneous formation of complexes in the bulk phase in certain concentration ranges. Under some conditions, compact monodisperse multichain complexes are obtained in the bulk. The size of these complexes depends on the mixing procedure and it can be varied in a controlled way from nanometers up
We present a theoretical study of two coupled diffusion processes through a membrane which is able to respond to the presence of the diffusing substances with a phase change. The case we consider is when the direct driving force for one of the processes vanishes, i.e. when the chemical potential of one of the components, or some other intensive variable, is kept equal in the two reservoirs surroun
A predicting model for soft dielectric elastomer generators (DEGs) must consider a realistic model of the electromechanical behaviour of the elastomer filling, the variable capacitor and of the electrical circuit connecting all elements of the device. In this paper such an objective is achieved by proposing a framework for reliable simulations of soft energy harvesters. In particular, a simple ele
The valence of the europium dopant and selected rare earth co-dopants (Ce3+, Dy3+, and Yb3+) in the Sr2MgSi2O7:Eu2+,R3+ persistent luminescence materials were studied by room temperature XANES measurements. The results indicated the co-existence of both divalent and trivalent europium in all the studied materials. The relative amount of Eu3+ was observed to increase upon increasing exposure to X-r
Newborn male infants have higher morbidity and mortality than female infants. Male fetal gender is associated with an overall increased risk of preterm birth and complications related to pregnancy are overrepresented in women carrying male fetuses. Several studies have shown that being newborn and of male gender are independent risk factors for adverse outcome. Even though experimental data from n
OBJECTIVE:: To compare the effects of ST-waveform analysis in combination with cardiotocography with conventional cardiotocography for intrapartum fetal monitoring. DATA SOURCES:: We searched MEDLINE, Embase, and PubMed for randomized controlled trials (RCTs) evaluating ST-waveform analysis for intrapartum fetal monitoring. METHODS OF STUDY SELECTION:: We identified RCTs that compared ST-waveform
Scavengers play a major role in the waste management process in developing countries. This study analyzed the informal recycling activities carried out by scavenger in the Tafila region of Jordan. The results show that scavengers have an important role in the informal solid waste management (SWM) especially in term of waste reduction, minimization and material recovery. Significant values from the
The complement (C') cascade is an important part of the innate immunity. It acts through three major pathways: classical (CP), alternative (AP) and mannose-binding-lectin (MP). C' reduction is a key feature in systemic lupus erythematosus (SLE), for its pathogenesis and for disease relapse. The aims of our study are to correlate C' variations with disease activity and verify the presence of C' def
Background: Meat intake may be related to weight gain because of its high energy and fat content. Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results. Objective: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain afte
A landscape genetics approach was applied to common goby (Pomatoschistus microps) sampled from three estuaries (six sites) of the Portuguese coast. Individuals of each site were genotyped for eight microsatellite loci and levels of genetic diversity and differentiation were correlated to present-day estuarine characteristics and historical events. A general ecological state for each sampling site
Sweden experienced a decline in inter-county real wage differentials for agricultural workers between 1860 and 1940, historical evidence of early labour market integration well before widespread unionization in agriculture occurred. By means of dynamic panel data analysis, this paper examines whether internal and external migration caused real wage beta convergence across Swedish counties. To acco
Popular Abstract in English Huntingtons sjukdom (HS), även kallad danssjukan, är en ärftlig och dödlig sjukdom som leder till ofrivilliga motoriska rörelser. Personer med HS får vanligtvis symtom i medelål- dern och avlider efter 15–20 år. Diagnosen ställs klinisk när de första ofrivilliga rörelserna uppträder. Dessa symtom kan kopplas till celldöd i de delar av hjärna som styr vår rörelse. SjukdoHuntington’s disease (HD) is a neurodegenerative disorder caused by an expansion of the CAG repeat in the huntingtin gene. Non-motor symptoms and signs such as psychiatric disturbances and metabolic dysfunction are also part of the disease manifestation. These symptoms often precede the motor symptoms by decades. The hypothalamus is an area in the brain involved in the regulation of emotions and m
PURPOSE. The authors recently showed that the retinal circulation can be accessed by transfemoral endovascular catheterization. The purpose of this study was to examine whether endovascular coiling can be used to induce different degrees of ischemic injury. The possibility of creating occlusions at different sites in the vasculature to cause retinal ischemia with different degrees of severity was
