Memory for pictures and words - perceptual and semantic factors in the picture superiority effect Georg Stenberg, Växjö University, Sweden Memory for pictures is known to surpass memory for corresponding concrete words, an effect often attributed to the more distinctive perceptual form of pictures. A consequence of this view is that picture superiority would not survive a transformation in which o

Many street vendors live under constant fear of eviction and harassment because the law does not recognize their businesses and they work outside the rule of law. Furthermore, in some cities street vending is a criminal offence to public order and vendors can be sent to prison. Using the empowerment theory, defended by Hernando De Soto, this article will examine to what extent formalization - unde

The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet

The acoustic field in an annular gas turbine combustion chamber with thirty burners has been studied using a hybrid approach. The acoustic field was determined by solving an inhomogeneous wave equation. The acoustic sources were provided by a low Mach number flow solver. The main focus was to determine the influence of nonuniform behavior and interactions of neighboring burners. For this reason th

Only during the last two decades has the discourse on evaluation been on the Swedish agenda of social work and social care. One assumption is that a conscious need for evaluation knowledge and evaluation capacity has finally surfaced. This based on the view that work efforts of social service organizations are regarded as chiefly authority-based and to a lesser degree based upon scientific knowled

Water resources management in water scarce regions like the Southern Africa Development Community (SADC) is challenging with both large hydro-climatic-induced scarcity and the considerable inter-annual fluctuations at the centre of the allocation problem. Water must be allocated both in time and space using acceptable criteria and most importantly, all stakeholders must adhere to the decisions imp

The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th

Differences in national legislations can affect the international competitiveness of an industry. For example, stringent EU regulations on animal welfare and environmental protection are often said to be a cost disadvantage for EU producers competing on the global market. However, in recent years, powerful retailers and food processors have started to impose requirements on downstream producers th

High-speed laser diagnostics was utilized for single-cycle resolved studies of the fuel distribution in the combustion chamber of a truck-size HCCI engine. A multi-YAG laser system consisting of four individual Nd:YAG lasers was used for planar laser-induced fluorescence (PLIF) imaging of the fuel distribution. The fundamental beam from the lasers at 1064 nm was frequency quadrupled in order to ob

In the drying section of a paper machine, steam heated cylinders are used to control the moisture of the produced paper. In previous work it has been shown that the dynamics from the steam valve to the steam pressure in the cylinder can be described by a linear second order black box process model. In this paper an equivalent model based on first principles is presented. The foundation of this mod
