We investigated protocerebral processing of behaviorally relevant signals in the turnip moth, Agrotis segetum. Single neurons were studied both physiologically and morphologically using intracellular recording techniques. In moth pheromone communication systems, the presence of the complete, female-produced pheromone blend is necessary for male attraction. We predicted that more protocerebral neur
Clinical physiologists in Sweden are physicians (the majority with a PhD degree) with thorough training in system physiology and pathophysiology. They investigate patients in a functional approach and are engaged in basic and applied physiology teaching and research. In 1954, clinical physiology was founded as an independent academic and clinical discipline by the Swedish government to ensure "con
Background: When scaling up lignocellulose-based ethanol production, the desire to increase the final ethanol titer after fermentation can introduce problems. A high concentration of water-insoluble solids (WIS) is needed in the enzymatic hydrolysis step, resulting in increased viscosity, which can cause mass and heat transfer problems because of poor mixing of the material. In the present study,
Terrestrial ecosystem models (TEMs) contain the coupling of many biogeochemical processes with a large number of parameters involved. In many cases those parameters are highly uncertain. In order to reduce those uncertainties, parameter estimation methods can be applied, which allow the model to be constrained against observations. We compare the performance and results of two such parameter estim
Brazil is the only country that has managed to successfully implement an economically viable large-scale biofuel program. In 2008, locally produced ethanol derived from sugarcane replaced more than half of the domestic gasoline market, without the aid of any government subsidies. Ethanol in Brazil represents an economically lucrative industry that also contributes to national energy and environmen
Problem area Alfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manag
Denna uppsats behandlar en nyligen avkunnad dom från Mark-och miljööverdomstolen. Rättsfallet som rör ett moderbolags miljöansvar för sitt helägda dotterbolags miljöskador är intressant både ur en miljö-och bolagsrättslig aspekt. Miljöansvaret faller primärt på verksamhetsutövaren och sekundärt på markägaren. Detta är reglerat i miljöbalken och har ägnats en hel del uppmärksamhet i praxis, förarbeThe present study deals with a recently delivered judgment from the Environmental court of appeal. The case deals with the issue of parent company liability for contamination, which is interesting from both an environmental and a company point of view. The environmental responsibility primarily lies on “the operator” and secondarily on the property owner. This is regulated in the Swedish environme
Kognitiv beteendeterapi (KBT) kan idag erbjuda evidensbaserade behandlingar för de flesta psykiska sjukdomar, men har inte utvecklats systematiskt för svagbegåvade personer med psykiska besvär. Individerna i denna osynliga befolkningsgrupp är emellertid extra sårbara för psykisk ohälsa pga sina sociala livsvillkor, samt sina psykobiologiska förutsättningar. Med stöd i forskning om KBT för lågbegåCognitive-Behavioural-Therapy (CBT) can today offer evidence-based treatments for most psychological disorders, but has not developed systematically for people with borderline intellectual functioning (IQ 70-85) and their psychological disorders. Individuals in this unseen population are, however, exceptionally vulnerable to psychological disorders because of their social life situation, as well a
Both numerical simulations and experiments were conducted in a heavy-duty DICI engine, with PRF81 as a gasoline surrogate, to investigate how the fuel stratification, auto-ignition and combustion are affected by the start of injection (SOI). The intake air temperature was adjusted to keep the combustion phasing constant when the SOI was swept from −100 to −20 oCA ATDC, covering different regimes o
The purpose of this paper is to discuss the conceptualisation of bibliometric analyses in terms of the levels on which they are performed, adding contextual factors to the dimension where the size of the unit being analysed is considered. Based on empirical investigations of resource allocation systems and research evaluation practices, as well as the previous literature conceptualising bibliometr
We ask what caused poverty to decline in Brazil during the first decade of the 21st century. Our contribution lies in the introduction of a structural change perspective to assess the evolution of poverty by considering the sectoral impact of growth and the social policies at the federal, state and municipal level. By structural change we mean the recomposition of output and employment over time.
During spring and autumn, many lakes in temperate latitudes experience intensive convective mixing in the vertical, which leads to almost isothermal conditions with depth. Thus the regime of turbulence appears to be similar with that characteristic of convective boundary layers in the atmosphere. In the present paper a simple analytical approach, based on boundary-layer theory, is applied to conve
Iridium(iii) half-sandwich complexes containing 7-chloroquinoline-1,2,3-triazole hybrid ligands were synthesised and their inhibitory activities evaluated against the Plasmodium falciparum malaria parasite. Supporting computational analysis revealed that metal coordination to the quinoline nitrogen occurs first, forming a kinetic product that, upon heating over time, forms a more stable cyclometal
In situ CO2 and CO measurements from five Integrated Carbon Observation System (ICOS) atmosphere stations have been analysed together with footprint model runs from the regional Stochastic Time-Inverted Lagrangian Transport (STILT) model to develop a dedicated strategy for flask sampling with an automated sampler. Flask sampling in ICOS has three different purposes, namely (1) to provide an indepe
As high technology device functionalities seem to constantly be moving towards decreasing critical dimensions and increasing density, there is a need for lithography research to move in the same direction. Block copolymer (BCP) lithography is a promising technique, which has single-digit nanometer resolution, typically has a pattern periodicity of 10-50 nm, and easily scales up the patterned area
A polymer electrolyte fuel cell (PEFC) is an electrochemical device that converts chemical energy directly to electrical energy, and its performance greatly depends on its operating temperature. Therefore, in this paper, a novel thermodynamic PEFC model with the airflow cooling method is firstly developed for the PEFC system. Then, a novel model predictive control (MPC) controller is designed to c
Purpose: This paper aims to investigate the nature and dynamics of the interaction between university spin-offs (USOs) and academia. Design/methodology/approach: The theoretical framework is grounded in an interactive view based on the industrial marketing and purchasing literature on USOs and their development. The concepts of activity links, resource ties and actor bonds are used as a starting p
The detailed dynamic modelling, simulation and optimisation of a batch distillation process at Bayer AG is presented. The model considers a mixture of 10 components separated in a 40 tray column. Simulations performed in the process modelling tool gPROMS proved that the model gives a very accurate description of the process behaviour. To increase the profit of the process an optimisation of the op
