Årskurs: 7-9, Gymnasiet Ämnesområde: Kraft och rörelse Hur högt en människa kan hoppa beror på hur högt hon förmår lyfta sin tyngdpunkt. Men var finns kroppens tyngdpunkt och kan vi påverka tyngdpunktens läge i kroppen? Med hjälp av en bräda får du svar på frågorna. Material  En cirka 2,5 meter lång bräda, 25 centimeter bred och minst 2-3 centimeter tjock. En kloss eller något liknande som kan fun

Lipids are organic molecules vital for living organisms. They are part of cell membranes and provide an important energy reserve once they are digested by our body. They are most commonly known as fats and oils. Some important so-called polar lipids are amphiphilic molecules, which means they have a head group that is water ‘loving’ (hydrophilic) and a hydrocarbon tail is water ‘hating’ (hydrophobNonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecu

Popular Abstract in English Alcohols and aldehydes are used in the chemical industry largely as a starting material for the manufacture of a wide range of products. They are also used as such in various industrial applications. The flexibility is due mainly to the functionalities of the alcohols and aldehydes being hydroxylic and carbonylic, respectively. Much interest is directed nowadays at convNowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan

This paper investigates and discusses four instruments found in a sixteenth century Spanish book of navigation. The night clock is a rather standard application of similar instruments known since the fourteenth century in Europe. Cortés’ explanation of the causes of the deviation of the magnetic and geographical north is quite original. His instrument to correct for that the Polaris deviates from

Autonomic dysfunction is a well-known feature in neurodegenerative dementias, especially common in α-synucleinopathies like dementia with Lewy bodies and Parkinson's disease with dementia. The most common symptoms are orthostatic hypotension, incontinence and constipation, but its relevance in clinical practice is poorly understood. There are no earlier studies addressing the influence of autonomi

The health impact of dietary replacement of carbohydrates with protein for patients with type 2 diabetes is still debated. This study aimed to investigate the association between dietary substitution of carbohydrates with (animal and plant) protein and 5-year weight change, and all-cause and cardiovascular (CVD) mortality risk in patients with type 2 diabetes.

This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. The distortion criterion is the mean squared error and the

PurposeTo investigate long-term effects of intravitreal injections on visual outcome, retinal function and structure in eyes with central retinal vein occlusion (CRVO eyes) and macular oedema and compare with untreated CRVO eyes to determine the long-term effects of anti-vascular endothelial growth factor on photoreceptor cell function.MethodsA retrospective study of 38 eyes from 38 CRVO patients.

The present study examined assertiveness and responsiveness in two different conversational contexts: children with specific language impairment (SLI) interacting with an age-matched peer with typical language development (TLD) and children with SLI interacting with a language-matched peer with TLD. The dialogues where the 10 participating children with SLI interacted with an age peer were charact

This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization). The proposed strategies depend critically on _events_, when a data packet is sent

A common problem in access control is piggybacking. This is when a person without authorized access sneaks closely behind another with access through a door. This thesis seeks to answer whether using radar is a viable solution when attempting to detect piggybacking. Detection will be made by classifying sequences of point clouds generated by the radar, using neural networks. The thesis compares tw

Digital control systems introduce unavoidable computational latencies. For some controllers this time delay inhibits practical use, even though they in theory could provide more efficient control. For example, solving an optimization problem each sampling period when using model predictive control. By sampling faster than the computation time and executing independent controllers on distributed ha
