Most often, the laminar burning velocity (SL) of ammonia was measured in mixtures diluted by nitrogen bearing in mind its potential use as an alternative carbon-free fuel. Replacing the diluent with argon can increase the flame temperature and thus provide additional targets for validating pertinent detailed kinetic models. The SL data for ammonia + oxygen + argon mixtures are scarce; therefore, i
Chronic myeloid leukemia (CML) is a myeloproliferative disorder caused by clonal proliferation of primitive hematopoietic stem cell. The median age at diagnosis is 55 to 60 years with less than 10% of patients younger 20 years. Incidence of CML in children in the Czech Republic is 0.106 cases/100 thousands per year. Here we report outcome of 38 pediatric patients (median age 12.5 years; range 1.8
Microorganisms have unique biochemical mechanisms to inhibit the growth or kill other microorganisms in the same environment. Bacterial threat agents (BTA) are more effective than conventional weapons because of these characteristics, therefore, the development and production of biological weapons are still relevant. Early warning signals need to be obtained for fast and accurate detection of BTA
This article explores how quantitative organological analysis can be implemented alongside historical musicology to help stimulate creativity in performance practice while promoting a diversity of timbre that is often lost amidst the hegemonic propagation of homogenized, normalized modern musical instruments. The tuba family provides an insightful case study demonstrating how the history and devel
BackgroundThe risk of developing Alzheimer’s disease (AD) is modulated by genetic and environmental factors. Early-life stress (ELS) exposure during critical periods of brain development can impact later brain function and health, including increasing the risk of developing AD. Microglial dysfunction and neuroinflammation have been implicated as playing a role in AD pathology and may be modulated
Holism, abduction and causality are ways of reasoning that can complement each other to enable better understanding of contemporary wicked problems. Current social challenges include a global housing crisis, unwanted isolation and polarized societies. Systems thinking is instrumental to zoom out a specific phenomenon in an attempt to capture the complexity of reality. It also provides a holistic v
Popular Abstract in Swedish Den rykande startpistolen eller Konsten att ta tid på en flygande elektron Flygande elektroner kan berätta mycket om hur världen sitter ihop. Elektroner som lämnar ytan av något material avslöjar både vilka atomer som finns i materialet och hur de kemiska bindingarna ser ut. Allt detta är nödvändigt att förstå när man vill utveckla nya material – till exempel för kretTime-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution. However, the advent of angle-resolved TOF spectrometers for electron energy analysis cha
Popular Abstract in English This book investigates marketing work in professional service organizations from a rhetorical perspective. It comes to the conclusion that this work is accomplished by self-reflexive marketers who are reminiscent of the ancient sophists – a diverse group of itinerant advisors whom came to Athens around the fourth century BCE for business reasons. Marketers travel – as d
Social movements in Malaysia have been traditionally exclusive in nature. Social movements in Malaysia have been limited by ethnic, social, and lingual barriers that constrained their capacity mobilizing the mass to overcome state constraints. However, the resistance of the Damansara New Village community against the State’s closure of the community school, Damansara Primary School, demonstrated t
The present thesis focuses on the numerical simulation of the flowfield in gas turbine burners. Due to the higher and higher requirements regarding pollutant emissions there is a need for new combustion technologies. In gas turbines one method to obtain low pollutant levels is the use of lean premixed or partially premixed combustion. However, in lean combustion problems regarding the flame stabi
