Perennial grain crops are gaining increased attention from researchers as one possible solution to agriculture’s many sustainability challenges. In the Sub-Saharan African context, perennial varieties of crops such as sorghum, rice, and pigeon pea have potential to provide numerous benefits for smallholder farmers. The introduction and adoption of new crops and practices is however a complex proce
This article offers narratives of individual journeys through the scholarship of leading in three different contexts—Asia, Europe, and Africa. Together, these narratives argue for the need to make explicit the diversity of practices of the scholarship of teaching and learning (SoTL), with each practice inextricably tied to specific geographical, sociocultural, and political contexts. In offering t
Den kände astronomen Tycho Brahe initierade meteorologiska observationer på ön Ven som noterades i endagbok, nästan oavbrutet från oktober 1582 till april 1597. Fastän observationerna huvudsakligen är kvalitativapå grund av dåtida brist på instrument och metoder kan en stor mängd användbar information erhållas fråndagboken beträffande molntäcke, nederbörd, vindhastighet och riktning, temperaturför
BackgroundCellulase enzymes have been reported to contribute with a significant share of the total costs and greenhouse gas emissions of lignocellulosic ethanol production today. A potential future alternative to purchasing enzymes from an off-site manufacturer is to integrate enzyme and ethanol production, using microorganisms and part of the lignocellulosic material as feedstock for enzymes. Thi
We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
Electrical brain activity and eye movements were recorded in 10 intact and 6 unilaterally labyrinthectomized rabbits, each with implanted electrodes. The frequency of optokinetic nystagmus (OKN) and a 10-second aggregate of theta waves in the dorsal hippocampus were determined after exposure of the animals to sound, vibration and optokinetic stimulation. Each stimulus used caused significant incre
A machine-learning and a string-matching approach to automated subject classification of text were compared, as to their performance, advantages and downsides. The former approach was based on an SVM algorithm, while the latter comprised string-matching between a controlled vocabulary and words in the text to be classified. Data collection consisted of a subset from Compendex, classified into six
The purpose of this study was to investigate illness experiences of patients after a first myocardial infarction (MI), focusing on life situation and the recovery process over time. Thirty patients were interviewed within the first 3 days of hospitalisation, and again 17 weeks after discharge. The interviews were tape-recorded verbatim and the transcriptions were analysed and categorised using qua
The rd1 mouse is a relevant model for studying the mechanisms of photoreceptor degeneration in retinitis pigmentosa. Treatment with ciliary neurotrophic factor (CNTF) in combination with brain derived neurotrophic factor (BDNF) is known to rescue photoreceptors in cultured rd1 retinal explants. To shed light on the underlying mechanisms, we studied the effects of 9 days (starting at postnatal day
In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a
Requirements engineering for commercial off-the-shelf software packages entails special challenges. This paper presents preliminary results from an empirical study investigating these challenges through a qualitative approach using semi-structured interviews. The survey is exploratory with the objective of eliciting relevant topics for further research. Seven employees at five software companies w
In order to reduce the vibration transmission in multi-storey wood buildings, it is common to insert viscoelastic elastomer materials between parts of the buildings. The studies presented here investigate to which extent different design choices for the elastomer layers affect the isolation of low-frequency vibrations (0-100 Hz). A finite element model of two storeys of a multi-storey wood buildin
Enterprise Resource Planning (ERP) systems have been used by organizations and companies the world throughout since 1990. Many universities have recently replaced their legacy systems with ERP systems to improve work efficiency. One solution available for universities by way of management information system is the Campus ERP system. The Campus ERP system helps universities incorporate all departme
To introduce a standardized component assortment takes a lot of effort in order to make real cost savings. The rationalization effect itself is important, but perhaps even more important is to state the aim of the standardization efforts in a well-defined way. How can an organization assure that they are working in a proper way? How do they know that their efforts are being interpreted into the wh
Enligt vår empiri kan lärande uppstå även i nätverk som inte är skapade med grundtanke att lära. Nätverksplattformen är en viktig grund för att lärandet ska kunna utvecklas, vi ser dock lite annorlunda på tid och resurser då teorin säger att den är tidskrävande, medan vi menar motsatsen. Vi anser även att Nätverksplattformen behöver kompletteras. Här utgör bland annat struktur och rutiner en vikti
Balans och psykologisk tilltro till fotledsfunktion vid idrottsutövande hos kvinnliga handbollsspelare efter en fotledsstukning Bakgrund: Handboll är en intensiv idrott och kännetecknas av ett stort antal högintensiva moment såsom hopp, tempoväxlingar, riktningsförändringar, dueller och kontaktsituationer. Handboll var en av de mest skadedrabbade sporterna under OS i London 2012 och under VM i Q
Syftet med denna studie är att ur ett livsvärldsfenomenologiskt perspektiv dokumentera sång-ares upplevelse av sitt sångtekniska och musikaliska lärande i grupp och i förekommande fall sätta detta i relation till deras upplevelse av en enskild undervisning, samt att studera vilka faktorer som kan ha varit utslagsgivande för dessa upplevelser. Studien är kvalitativ och genomfördes som aktionsforsknTitle: Individual development in group - voice lessons together with and through others. The purpose of this study is to, from a life-world phenomenological point of view, document how singers experience their vocal technical and musical learning in group and in to relate this to their experience of a private lesson and to study what factors have been decisive for these experiences. This study is
Studiens avsikt är att undersöka den information man kan få fram med hjälp av undersökningsinstrumenten, Adult Attachment Interview och Inventory of Interpersonal Problems och syftar till att belysa dessas användbarhet i en klinisk kontext. Studien bygger på både kvalitativ och kvantitativ metod, vilket innebär, semistrukturerade intervjuformulär, fallbeskrivning samt självskattningsformulär. Stud
