Sexual conflict and selection on pistil and pollen traits

Popular Abstract in Swedish Konflikter och sexuellt urval under pollenkonkurrens Naturens många fantastiska färger och former har till stor del skapats av det sexuella urvalet, det vill säga selektionstryck som skapas av konkurrens och val, som uppstår till följd av att djur och växter fortplantar sig. Det var Darwin som 1871 presenterade teorin om det sexuella urvalet i ett försök att förklara vThe incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. Using the hermaphroditic annual herb Collinsia heterophylla, I looked deeper into the role of pollen-pollen comp

Barns behov av information, råd och stöd när en förälder är psykiskt sjuk - Hur efterföljs lagen? En utvärdering av implementeringen i Psykiatri Skåne

Omfattande forskning pekar på att en förälders psykiska ohälsa kan utgöra en riskfaktor för barnens psykiska utveckling och hälsa. Man räknar med att cirka 30 procent av patienterna i vuxenpsykiatrisk vård har minderåriga barn. Under ett år får cirka 30 000 patienter vuxenpsykiatrisk vård i Skåne. Sedan år 2010 finns ett tillägg i hälso- och sjukvårdslagen som slår fast att vården ska beakta barne

The potential of Supplemental Instruction in engineering education

The results from this study show that both the percentage of students passing a difficult first-year engineering course, and scores on the course exams, are higher for students attending SI compared to students not attending. There is also a clear relation between SI attendance and student performance, with higher attendance leading to higher student performances. The study also shows that female

The Dynamics of Innovation Clusters. Examples from the Food Industry

The book provides an in-depth analysis of the processes of innovation found in industrial clusters. The Authors focus particularly on the characteristics of innovation clusters and their operation in the food industry. This is revealed through novel case studies, detailed research on dynamic cluster relationship between academia and the industry, and the role of competencies, resources, interactio

Relationship between chemical structure and airway sensitizing potential for organic acid anhydrides : an animal model

Oranic acid anhydrides (OAAs) are important reactive, low-molecular-weight industrial chemicals which induce allergic rhinitis and asthma in exposed subjects. Specific IgE has been demonstrated in a large proportion of OAA-exposed workers. The characteristics of the OAAs make them excellent model compounds for studies of quantitative structure-activity relationships (QSAR) of allergenicity. In the

Geophysical Investigation of a Rural Water Point Installation Program in Nampula Province, Mozambique

There are many projects in Mozambique for poverty reduction. One of these projects is funded by Millennium Challenge Account (MCA) and is aimed to install a total of 600 rural water points in the province of Nampula and Cabo Delgado in crystalline rock zone. Each water point consists of a drilled well, a water pump and a communal washing basin. Vertical Electrical Sounding (VES) was used for asse

Proteome Profiling of Strawberry and Characterization of a Bet v 1-Homologous Allergen

Popular Abstract in Swedish Denna avhandling visar att jordgubbar innehåller ett allergen, proteinet Fra a 1, som är mycket likt det allergen som orsakar besvär vid björkpollen-allergi. Den som får allergiska besvär av jordgubbar, t.ex. att det kliar och blir irriterat i munhålan och svalget när man äter , har ofta en björkpollen-allergi sen tidigare. Motsvarande allergen finns också i en del andrStrawberry (Fragaria ananassa) is an economically important crop, and recognised as an important source of antioxidants and bioactive compounds with health promoting effects. Yet increased incidence of allergy puts a limit to the choice of food for an increasing percentage of the population. As part of this thesis a strawberry allergen termed Fra a 1 was identified, which is related to a major bi

Navigating the world and learning to like it - mobility training through a pervasive game

This paper introduces the idea that location based pervasive games can be used to make mobility training for visually impaired children more fun. The user centred development process which has been carried out in collaboration with both visually impaired children and rehabilitation staff is described and we present a novel game concept which combines locative play, sound traces and a physical catc

Thermo- and chemosensitive properties of Transient Receptor Potential Ankyrin 1 ion channels

Popular Abstract in English All living things have the ability to detect and respond to changes in the surrounding environment and most of us take sensations caused by changes in light, sound, taste, temperature, and touch for granted. However, the process of detection and transmission of the signal generated to the brain is quite complex and some aspects not known. This thesis explores the sensorThe ability to sense and accommodate to an ever-changing environment is crucial for the survival of living organisms. Transient Receptor Potential (TRP) ion channels comprise a large superfamily of cation conducting membrane proteins that function as molecular sensors in diverse sensory processes including perception of light, taste, smell, sound, touch and temperature. The TRP Ankyrin 1 (TRPA1) i

On-line simulation tool for the design and analysis of lower-limb prosthetic devices

This paper presents a new and practical simulation interface to design and analyze lower-limb prosthetic devices. The proposed tool simulates the gait of a lower limb amputee using a desired prosthetic device. It allows the analysis of simple passive devices or the testing of control algorithms for active prostheses. The results presented in this paper correspond to the use of this tool to test a

Evaluation of the injection force dynamics of a modified prefilled insulin pen

Objective: A modified version of the widely used pen FlexPen® (FP), called Next Generation FlexPen® (NGFP), has been designed to reduce the injection force with this pen. In this study, the injection force of NGFP was compared with another insulin pen, SoloStar® (SS). Research design/methods: The injection force of 24 pens of each type: NGFP fitted with a NovoFine® 32G Tip ETW 6 mm needle; SS fitt
