ABSTRACT The existence of sound symbolic and mimetic words in the Japanese language is well known. Although the most common appearance of these sound symbolic words occurs in Japanese comics they do exist in many other forms of media, ranging from television shows to everyday conversation. These words, a very good tool for the native Japanese speaker to convey intimate meanings and sensations, po

The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. All these storage systems induce multidimensional, time-variable thermo-hydr

The immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. This thesis work is based on investigations of different tolerance mechanisms induced in CD4+ T lymphocy

Visstidsanställningar har en viktig roll i strävan efter ökad flexibilitet men konsekvenserna av anställningsformens tillämpning och förekomst har länge varit omdebatterade. År 2007 inledde EU-kommissionen ett överträdelseärende efter det att TCO anmält Sverige för brister i implementeringen av visstidsdirektivet 1999/70/EG som bland annat syftar till att förhindra otillåten stapling av visstidsan

This thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus). Overall, the results show that both crayfish species are omnivores having strong direct and indirect effects o

An increasing number of robots have been used for the finishing of castings during recent years. This is mainly due to developments to overcome problems that restricted their use during the past decade. The major difficulties have been the need to control reaction forces during metal removing by grinding operations and the lack of tools designed specially for robots. The elimination of these two p

The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine de

Convetional brass is still allowed to contain up to 3.5 wt.% lead even though lead is a hazardous metal. However, due to environmental concerns lead-free brasses are becoming increasingly available. The aim of this paper is to evaluate the machinability of a lead-free brass alloy, CuZn21Si3P, as compared to a convetionally used, lead-alloyed alternative, CuZn39Pb3. The attained results show that C
