The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Hämning (Behavior Inhibition) tycks utgöra en riskfaktor för olika typer av ångestsyndrom. Child Inhibition Scale (CIS) är ett föräldraformulär som mäter hämning hos barn. Syftet med studien är att normera samt att psykometriskt utpröva den svenska versionen av CIS mot ett föräldraformulär som mäter generell ångest hos barn och ungdomar Multidimensional Anxiety Scale for Children ? Parent version (MASC-P). I studien ingår skolor från fem områden i Storstockholm.

Barn med funktionsnedsättningar har ofta problem i skolan men även i deras vardag på grund av att deras omgivning inte är ämnad för människor med någon typ av svårighet. Prospektivt minne är en viktig faktor i hur väl en person med funktionsnedsättning klarar av sin vardag. Tidigare studier visar även att det finns en koppling mellan den exekutiva funktionen inhibition och prospektivt minne. Denna studie har i syfte att undersöka om det finns ett samband mellan den exekutiva funktionen inhibition och prospektivt minne. Detta behövs för att få en större förståelse för vad som orsakar svårigheter i vardagen för personer med funktionsnedsättningar.

The problem of finding targeted medicine is a central problem in chemotherapy. From this point of view the ubiquitin-proteasome system is a highly promising object in the pharmaceutical approach. Proteasome plays a critical role in cellular protein degradation, cell cycle and apoptosis regulation.Proteasome inhibitors are substances blocking the actions of proteasome. Cancer cells are more sensitive to inhibition of the ubiquitin-proteasome system than normal cells. Therefore proteasome inhibitors have the potential to be successfully used in the cancer treatment.The study aimed to test various substances to identify possible proteasome inhibitors with the IncuCyteTM FLR image system and fluorometric microculture cytotoxicity assay.

When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.

The subject of this paper is the congestion tax in Stockholm, Sweden. The study has been conducted with the purpose to examine of how public attitudes towards congestion charging looks and the reason behind the attitude. And also to examine if there are any differences in attitudes between those living inside and outside the payment zones, between men and women and between car owners and those who do not own a car or have a driver's license. The study used a questionnaire sent out electronically to a group of friends of friends and of friends? family members.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

I denna uppsats undersöker vi Export Processing Zones (EPZ) roll i ett lands ekonomiska utveckling, exemplifierat med Mexico. Fokus för uppsatsen är centrerat kring de bakåtriktade länkeffekter som förväntas uppstå som en effekt av ett EPZ-program. Fenomenet längs den mexikansk-amerikanska gränsen kan sägas ha flera orsaker, men grundas i tillgången på billig arbetskraft samt närhet till världens enskilt största konsumentmarknad. Uppsatsen visar på ett minskat FDI-inflöde, ökad sysselsättning, begränsad teknologiöverföring samt mest jobbspecifik kunskapsöverföring. Eftersom få lokala eller inhemska underleverantörer kontrakteras av EPZ-företagen minimeras länkbildningen.

Prematurfödda barn drabbas oftare av uppmärksamhetsstörningar, ångestproblem, isolering samt sociala problem och färdighetsbrister än fullgångna barn. Uppsatsens syfte är dels att undersöka om en grupp prematurafödda beter sig mer inhiberat än fullgångna, dels undersöka sambandet mellan inhibering och överbeskydd, då tidigare studier visat på en samvariation mellan ett överbeskyddande föräldraskap och beteendeinhibering. Gruppen på 20 prematurfödda barn (VLBW) och 20 kontroller bedömdes med sina mammor vid 3 och 24 månaders ålder med The Parent-Child Early Relational Assement. I 20-gruppen ingick 16 prematurfödda som även bedömdes i en större grupp (177 prematurfödda, 120 kontroller) vid 51/2 års ålder avseende självförtroende och blyghet. Resultaten visar på en signifikant huvudeffekt av prematurfödsel avseende inhiberat beteende vid 24 månader.

The understanding of the role of nature for rehabilitation of both physical and psychological afflictions has greatly increased in the last few years. There?s a lot of science that describes the healing effects of nature. The rehabilitation garden in Alnarp has contributed with very positive results from the treatments of patients with burnout syndrome. In the first stages of rehabilitation, the need for calm is very important and a demand-less and stress-free environment is of essence.

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Denna studie berör olika developer zones som idag drivs av företag i Sverige, och om hur dessa är uppbyggda. Den tar upp de problem som dessa företag har stött på, samt vad man ska tänka på vid uppstart och användning av en developer zone.Att låta sin developer zone vara helt öppen eller helt stängd är inte det mest optimala sättet eftersom man i den helt öppna versionen låter sin information vara tillgänglig för allt och alla. Den helt stängda versionen stänger ute kunskap från developer zonen. Genom att sätta upp en developer zone med båda delarna, dvs. en öppen del för utvecklare som intresserade att utveckla innovativa tjänster/produkter och en stängd del för företag som tillsammans med ägaren av developer zonen har ett ekonomiskt intresse, så uppnår man en mer kontrollerad form.
