Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

Motsättningar i det harmoniska samhällets gryning: En studie av sambandet mellan rule of law och rättmätigt motstånd i Folkrepubliken Kina

År 1999 infördes principen om rule of law i Folkrepubliken Kinas konstitution - lagen skulle styra landet. De år av vanstyre som nådde sin kulmen under kulturrevolutionen hade åsidosatt lag och ordning och hade lett till att Folkrepubliken Kina vid tiden för Deng Xiaopings maktövertagande i slutet av 1970-talet stod utan ett rättssystem. Vid sidan om den ekonomiska reform som skulle öppna upp landet för världen gjordes därför enorma insatser för att etablera ett fungerande rättssystem. De kinesiska medborgarna fick många nya lagstadgade rättigheter, men på många håll runt om på den vidsträckta kinesiska landsbygden tillämpades lagarna inte till fullo av lokala styren som skaffade sig förmåner genom att inte tillämpa alla rättigheter. Bland de människor som inte fick ta del av rättigheterna formades rättmätigt motstånd ("rightful resistance") - motstånd med stöd av lag - som riktades mot illojala kadrar på lokal nivå.Sedan dess har rättmätigt motstånd ökat och är en aktuell fråga i dagens Kina.

Har kombinerad konditions- och styrketräning en hämmande effekt på utvecklingen av muskelstyrka jämfört med enbart styrketräning?: En systematisk litteraturstudie

Introduktion: Under de senaste tre decennierna har forskare försökt nå konsensus kring frågan om den möjliga hämmande effekten av kombinerad konditions- och styrketräning avseende utveckling av muskelstyrka jämfört med enbart styrketräning. Senaste meta-analysen inom området fastställdes 2012 och har kartlagt forskningsresultat fram till 2008, där konklusionen påvisar att forskningsresultaten är tvetydiga. Syfte: Att genomföra en systematisk litteraturstudie i form av en aktuell kunskapssammanställning över den forskning som bedrivits inom området för kombinerad konditions- och styrketräning för att undersöka om kombinerad träning har en hämmande effekt på utvecklingen av muskelstyrkan. Metod: Studien är en litteraturgenomgång där data samlats in via de medicinska databaserna; PubMed, Web of science, CINAHL, Scopus, AMED, Cochrane library och Physical education index. De sökord och sökordskombinationer som användes var; Concurrent training AND Endurance training AND Combined, Concurrent training AND Physical fitness AND Resistance training och Concurrent training AND endurance training AND Resistance training.

Antibiotikaresistensgener: förekomst och spridning i akvatisk miljö

Antibiotikaresistens hos bakterier har de senaste årtionden ökat drastiskt och är idag en av de största medicinska utmaningarna samhället står inför. Resistensutvecklingen har ökat i takt med den oförsiktiga användning av antibiotika som präglat både sjukvård och djuruppfödning i många år. Via akvatisk miljö har antibiotikaresistensgener stora möjligheter att spridas och är svårkontrollerbara. Den här litteratursammanställningen undersöker vilka ursprung antibiotikaresistensgener i akvatisk miljö kan ha och om det kan ske en horisontell genöverföring mellan bakterier. Vidare undersöks olika risker med antibiotikaresistensgener i akvatisk miljö, vilken möjlig roll de kan ha i resistensutvecklingen och hur de kan spridas tillbaka till människor och landlevande djur. Antibiotikaresistensgener i akvatisk miljö kommer ifrån utsläpp av resistenta bakterier från djuruppfödningar, akvakultur, sjukhus och bostäder.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Vanans makt : En kritisk granskning av Pierre Bourdieus bidrag till aktör-strukturdebatten genom George Herbert Meads tänkande

The purpose of this essay is to critically review Pierre Bourdieus contribution to agency ? structure debate. I will do this with help from the thinking of George Herbert Mead. My aim is to show that Mead can provide valuable knowledge to Bourdieus theory.Pierre Bourdieus notion of habitus is his solution to the dilemma between agency and structure. It is in the habitus that the objective structures meet the inner, subjective structures and this results in various actions.

Viskleken : Ett gestaltande arbete från text till upplevelse

In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.

Den obeorende revisionen och god revisorssed enligt revisorslagen

Several industrial scandals, especially those about Enron and WorldCom, have lead to an intense debate about the independent audit and the independent auditor. A substantial part of the auditor?s income originates from counselling, and therefore the role of the auditor may be seen as double, and the auditor?s objectivity may be questioned. In the year of 2002, a new Auditors Act was legislated in Sweden. In the 21 § of the act, a model based on principles was introduced, to test the auditor independence in every single case.

KONTROLLBERÄKNING AV ETT TAKRAS PÅ EN TENNISHALL I NYKÖPING : En jämförelse mellan Eurokod och BKR

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

Simulering av översvämningar i Byälven

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Analys av spänningsstabilitetsberäkningar i det svenska elsystemet

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

Ibn Khaldun om Banu Umayya : Historieskrivningen om det umayyadiska kalifatet och dess återgivelse i al-Muqaddima

The history of Banu Umayya has since the collapse of the caliphate occupied a major part in Islamic historiography. The present thesis analyses the presentation of the Umayyads in Ibn Khaldun?s al-Muqaddima and its relation to previous historical traditions. The thesis examines the social and intellectual context in which Ibn Khaldun stood and how it is represented in his historiography, while also providing an overview of the various socio-political, intellectual and historiographical developments in Islam. The theoretical perspectives are based on the concept of agency, examining the intellectual room for manoeuvre that the historian disposed of while composing the works.

emotional ownership and the fan fiction community

”Fan fiction writing”, or the writing of stories based upon a popular entertainment franchise, has become a topic of academic discussion. Fan fiction writers have waked the ire of movie producers, since they often write fiction that is in direct contradiction to the movie’s plot or spirit. While most academic studies on fan fiction have concentrated on his confrontational aspect of the writers’ psyches, we have found that the writers actually have a much more nuanced approach to their work, and are not necessarily hostile towards the directors and producers. Even more surprising is the fact that the internet, beyond giving the writers a forum to post their writings, has potentially had a transformative impact on how the writers interact with each other and with the outside world. .
