Today's rapidly evolving and changing market dictates constant changes in design requirements during the development process of a product. If development teams are unable or unwilling to adapt to these changes, this will ultimately lead to an uncompetitive product. How the change in requirements will affect the development process depends on the complexity of the product and the development phase
Two methods for estimating the sensor offset of a cylinder pressure transducer are developed. Both methods fit the pressure data during pre-combustion compression to a polytropic curve. The first method assumes a known polytropic exponent, and the other estimates the polytropic exponent. The first method results in a linear least-squares problem, and the second method results in a nonlinear least-
The heat transferred to the turbine blade is substantially increased as the turbine inlet temperature is increased. Cooling methods are therefore much needed for the turbine blades to ensure a long durability and safe operation. The blade tip region is exposed to the hot gas flows. A common way to cool the tip is to use serpentine passages with 180-deg turn under the blade tip cap taking advantage
BACKGROUND: Cyclin A1 is a cell cycle regulator that has been implicated in the progression of prostate cancer. Its role in invasion and metastasis of this disease has not been characterized. METHODS: Immunohistochemistry and cDNA microarray analyses were used to assess protein and mRNA expression of cyclin A1 and proteins with roles in metastasis, including vascular endothelial growth factor (VEG
Intratumoral heterogeneity is an inherent feature of most human cancers and has profound implications for cancer therapy. As a result, there is an emergent need to explore previously unmapped mechanisms regulating distinct subpopulations of tumor cells and to understand their contribution to tumor progression and treatment response. Aberrant platelet-derived growth factor receptor beta (PDGFRβ) si
We have made a study by isothermal calorimetry of the heat production response of root and tuber tissue to wounding. Samples with different surface to volume ratios were prepared from carrots, potatoes and swedes (rutabaga) and the overall metabolic heat was measured in closed glass ampoules in a TAM Air isothermal calorimeter. The evaluation was made by assuming that a certain heat production rat
Cytokines play a major role in lymphoid development. Defects of the common gamma chain (gamma (c)) or of the JAK3 protein in humans have been shown to result in a severe combined immune deficiency (SCID), with a profound defect in T and natural killer (NK)-cell development, whereas B-cell generation is apparently unaffected (T-B+NK- SCID). While extensive molecular and biochemical analysis of thes
Popular Abstract in Swedish Att vara äldre, beroende av hjälp och leva med varaktig smärta. För äldre människor som är beroende av hjälp från omvärlden för att klara av sitt dagliga liv, utgör inte bara den nedsatta funktion ett problem. Många är drabbade även av andra problem, varav ett vanligt är ihållande och varaktig smärta. För vissa äldre med gravt nedsatt funktion kan språket ha drabbat's This thesis explores everyday living with persistent pain from the perspectives of functionally dependent older persons in pain and of staff. A combination of qualitative and quantitative methods was chosen. Data were collected using interviews and tools for assessing pain. The first data collection included 66 persons (65+) living in sheltered accommodation and their corresponding contact nurses.
Introduction: as South Africa's maternal mortality ratio increased between 1990 and 2015, the country failed to reach the United Nations millennium development goal 5a. The maternal mortality ratio of Limpopo province is higher than the national average and previous studies report shortages of manpower and medical equipment in Limpopo province. The overall study aim was to elucidate views and expe
Tumor-associated macrophages (TAMs) continuously fine tune their immune modulatory properties, but how gene expression programs coordinate this immune cell plasticity is largely unknown. Selective mRNA translation, controlled by MNK1/MNK2 and mTOR pathways impinging on eIF4E, facilitates reshaping of proteomes without changes in abundance of corresponding mRNAs. Using polysome profiling developed
Background: Infectious complications in ANCA associated vasculitis (AAV) are a major cause of morbidity and mortality. The aim of this study was to determine the incidence rates, predictors and outcome of severe infections in AAV. Methods: We conducted a population-based cohort study in Southern Sweden with 326 incident cases of AAV diagnosed between 1997 and 2016. Diagnosis of vasculitis was conf
För att mildra förlusten av biologisk mångfald i jordbruksmarker, inklusive dess pollinatörer, har många ansträngningar ägnats åt att bevara naturbetesmarker och slåtterängar. Dock är redan förlorade naturbetesmarker och slåtterängar svåra att återställa och kostsamma att hantera för ökade fördelar för biologisk mångfald. Dessutom är idag många marker som tidigare användes till slåtterängar nu betTo mitigate loss of farmland biodiversity, including insect pollinators, much effort has been spent on preserving semi-natural grasslands. However, already lost grasslands are difficult to restore and costly to manage for increased benefits to biodiversity. Previously often mowed semi-natural grasslands are today mostly managed by grazing, resulting in a lack of critical floral resources for many
Background The impact of baseline anemia in a contemporary acute coronary syndrome (ACS) population undergoing percutaneous coronary intervention in the era of predominant radial artery access, potent P2Y12 inhibition, and rare use of glycoprotein IIb/IIIa inhibitors has not been adequately studied. Methods and Results ACS patients who underwent percutaneous coronary intervention between 2014 and
Parasites are expected to exert long-term costs on host fecundity and longevity. Understanding the consequences of heritable polymorphic variation in disease defence in wild populations is essential in order to predict evolutionary responses to changes in disease risk. Telomeres have been found to shorten faster in malaria-diseased individuals compared with healthy ones with negative effects on lo
Purpose of this paper The purpose of this article is to explore themes and challenges in making logistics environmentally sustainable with a complexity theoretical perspective. Design/methodology/approach The research is explorative and based on a cross-sectional design focusing on different entities of supply chains. The study set out with a systematic review and content analysis of articles in
Extracellular histones are present in the airways because of cell death occurring during inflammation. They promote inflammation and cause tissue damage due to their cationic nature. The anionic phosphoglycoprotein osteopontin (OPN) is expressed at high levels during airway inflammation and has been ascribed both pro- and anti-inflammatory roles. In this study, it was hypothesized that OPN may neu
The objective for this study was to investigate whether the postural control adaptation during galvanic stimulation of the vestibular nerve were similar to that found during vibration stimulation to the calf muscles. A method for adaptation analysis was used to analyze the evoked changes of posture, stimulus responses and the motion dynamics. The adaptive adjustments of postural control were simil
