Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden
The
focus
of
this
project
was
to
characterize
the
occurrence
of
ESBL-?producing
bacteria
in
two
irrigation
water
ponds
in
Southern
Sweden.
Samples
were
taken
from
two
ponds
nearby
each
other,
from
which
analyses
were
made
based
on
levels
of
community
and
individual
isolates.
Community
samples
were
used
for
attempts
for
characterization
of
resistance
patterns
in
irrigation
water
using
the
Omnilog
PM-?plate
system.
The
growth
of
community
microbiota
in
the
presence
of
the
following
antibiotic
substances
was
assessed;
amikacin,
gentamicin,
kanamycin,
penicillin
G,
ampicillin,
piperacillin,
trimethoprim,
potassium
tellurite
and
ciprofloxacin.
Isolates
were
pure
cultured
using
semi-?selective
media:
LB,
Rainbow
Agar,
mEnterococcus,
0.1
TSA
and
VRBD.
A
total
of
177
isolates
were
isolated
randomly.
Each
isolate
was
identified
using
the
Omnilog
GENIII-?system
of
biochemical
characterization.
Further,
the
isolates
were
tested
on
Brilliance
ESBL-?agar
for
their
ability
to
grow.
Out
of
the
total
number
of
isolates,
30
were
selected,
preferably
Enterobacteriaceae
or
Pseudomonas
spp.,
based
on
their
high
similarity
to
library
strain
during
the
identification
in
the
Omnilog-?system.
These
were
further
characterized
using
Etest-?sticks.
Three
selected
strains
were
picked
for
further
analyses
using
exogenous
isolation
for
attempts
to
simulate
horizontal
gene
transfer,
and
Omnilog
PM-?panels
containing
various
antibiotics
of
interest.
Selections
of
samples
were
chosen
for
molecular
tests
targeting
plasmid-?borne
resistance
genes
CTX-?M1,
CTX-?M2
and
SHV.
The
method
for
assessing
community-?resistance
patterns
showed
ambiguous
data
that
was
difficult
to
interpret;
further
optimization
is
recommended.
For
all
tested
PM-?plates,
generally
greatest
differences
between
substances
were
found
among
wells
with
the
strongest
concentration
of
antibiotic
substance.
A
total
of
175
isolates
displayed
ability
to
grow
on
ESBL-?agar.
Etests
confirmed
ability
of
isolates
to
resist
many
?-?lactam
antibiotics
and
many
were
clinically
resistant
to
certain
substances.
No
plasmids
were
transferred
during
exogenous
isolation.
During
molecular
tests,
a
few
matches
were
found
for
the
CTX-?M1
gene.
Isolates
analyzed
with
Omnilog
PM-?plates
showed
resistance
to
most
compounds
tested.
The
isolates
showed
greatest
resistance
toward
penicillin
G,
ampicillin,
amikacin,
kanamycin
and
trimethoprim.
In
the
study,
it
was
established
that
resistance
among
bacteria
was
frequently
occurring
in
the
irrigation
water,
and
?-?lactamase
producing
bacteria
was
very
common.
Extended
studies
are
needed
to
assess
the
frequency-?
and
occurrence
of
horizontal
gene
transfer
(HGF)
in
this
environment.
Although
some
potential

data
is
found,
it
is
at
this
point
not
possible
to
determine
whether
the

Design- och marknadsundersökning av en applikation för smartphone
?Medicines are available in different forms and often have different types of compound components. More and more drugs are found on the market. This means that professionals who handle different medicines must have access to more and more information.The information available includes information about side effects, active substances, interactions and pill identification. You may want to access different information, depending on your profession.
Prehospital smärtbehandling hos patienter med misstänkt höftfraktur : en retrospektiv journalstudie
SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.
Ekosystemansatsen på landskapsnivå
The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA). In this thesis it is analyzed how the EA approach could be applied to regional management of coastal areas in Sweden. The aim of this report is to compare management for preserving biodiversity on a landscape level in two regional coastal areas in Uppsala and Västra Götaland respectively. In Uppsala, one of the plans consists of a previous nature reserve and in Västra Götaland, a Regional landscape strategy has been established. The ecosystem approach is used as a theoretical framework in this thesis.
Implementering och kommunikation av ekologisk h?llbarhet. En fallstudie om utmaningar och strategier i fordonsindustrin
The purpose of the study is to explore the internal implementation and communication of ecological sustainability within an organization and to identify obstacles and challenges that may arise. To address the study's purpose and research questions, a qualitative methodology
and semi-structured interviews were used. Respondents were selected from two different units within a large global organization operating in the automotive industry. The study's findings indicate that the organization's sustainability efforts are extensive and integrated
across several departments. It is also evident that sustainability initiatives are primarily driven by upper management within the organization, although there is room for lower hierarchical levels to provide some feedback.
Etanol : ett hållbart tankande eller ett kortsiktig tänkande?
Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.
Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav
The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.
Man behöver inte vara officiellt deprimerad Om biblioterapi som biblioteksverksamhet, med Kirklees i England som exempel
The purpose of this thesis is to examine if and how bibliotherapy can be part of ordinary work in Swedish libraries. Questions: what is bibliotherapy and who can work with it? What are the conditions required? What does it mean to people taking part and to libraries? In this study bibliotherapy is delimited to fiction and activities including discussions, excluded are self-help books and the individuals private reading. The study is based on four qualitative interviews with librarian and bibliotherapists in Kirklees, England, partaking in nine bibliotherapeutic sessions and a literary survey, together forming a case-study. Conclusions: There is not a single answer to the question what bibliotherapy is, but if one puts stress on the biblio- part of the word, seeing reading as a normal activity it can be part of library work, whereas the therapy- part should be dealt with by professionals outside libraries.

Svenska miljömål på byggprogrammet? - Ett sätt att integrera hållbar utveckling i karaktärsämnet
Syftet har varit att undersöka om de Svenska miljömålen kan vara ett sätt att göra hållbar utveckling synlig för elever på byggprogrammet. Det har också varit att ta reda på vilka mervärden som kan skapas genom att hållbar utveckling synliggörs genom att miljömål integreras i undervisningen. Delmålen är verklighetsnära och direkt kopplade till byggbranschen, vilket kan medföra ett ökat engagemang och vilja till att medverka till förändring.Resultatet visar att yrkeslärare, elever och platschefer på byggföretag inte hade kännedom om miljömålen. Svenska miljömål behöver integreras i karaktärsämnena på byggprogrammet för att politiskt fattade beslut om vad som krävs för att vi ska kunna nå hållbar utveckling förmedlas till de elever som skall ut i yrkeslivet, så att de kan komma ut med en handlingskompetens som kan leda till förändring. Nästan samtliga var överrens om att det skulle kunna ge mervärden att ha kunskap om hur de i sin vardag kan arbeta med hållbar utveckling.
Planering och exploatering i fjällnära natur
Detta kandidatarbete handlar om planering, exploatering och naturvärden i den
svenska fjälen. Syftet med denna uppsats är att studera och analysera hur
planering och exploatering i de svenska fjällen påverkar den naturmiljön som
finns där. En del av syftet består av att studera hur turismen påverkar
planeringen, en annan del är att se hur naturmiljön påverkas av exploateringar.
Genom exempel i från den planerade exploateringen av Rödkullen i Åre kommun
skall problem och möjligheter som kan uppkomma vid planering och exploatering
belysas. En fallstudie har gjorts på Rödkullen i Åre, ett naturområde som inom
snar framtid ska exploateras.

ATT UNDERVISA FÖR HÅLLBAR UTVECKLING : Sex lärares uppfattningar
?Syftet med studien är att undersöka hur ett antal lärare, som har genomgått Grön Flaggs utbildning, uppfattar sitt arbete med handlingskompetens för hållbar utveckling. Frågeställningarna rör hur lärare förhåller sig till olika typer av direkta/indirekta påverkanshandlingar för hållbar utveckling i sin undervisning/verksamhet samt vilka drivkrafter och hinder lärarna uppfattar för att implementera ESD (Education for Sustainable Development).För att besvara våra frågeställningar använde vi oss av en enkät som genomfördes muntligt med sex lärare som arbetar inom de tidiga skolåren. Vi gjorde enkäten muntligt för att få kommentarer/motiveringar till deras svar och på så sätt kunna behandla materialet kvalitativt.Resultatet visade att lärarna uppger sig behandla både direkta (till exempel att källsortera) och indirekta (till exempel att påverka beslutsfattare) påverkanshandlingar, men att de direkta överväger. Många av de drivkrafter och hinder som forskare tidigare har kunnat identifiera framkom även i vår studie, men det framkom även andra, till exempel sådant som har att göra med elevernas engagemang och praktiska förutsättningar.
På vandring mot handling : Utbyte av perspektiv i landskapet
Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.
Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter
Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
