Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?
The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity.
Many insects are attracted to the smell of fermenting fruit and associated microorganisms.
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,

Motiv och motivation bakom volonta?rism i extrema situationer. : En kvalitativ studie om Volunteer Function Inventory och dess beha?llning som analysverktyg.
This study is based on the notion that the most widely cited and used instrument for assessing volunteer motivations, the Volunteer Function Inventory (VFI), might not be sufficient in its aspiration to aid, streamline and benefit the recruitment and retention process within volunteer organizations. Understanding volunteers? motivation is a crucial component in the process of securing future volunteer engagement in a world where their efforts are desperately needed.This study aims to explain motives and motivation behind volunteer efforts in extreme situations as well as to examine the dependability of the theoretical framework in relation to the forthcoming result, based on the following research questions:What motivated Swedish medical personnel to volunteer during the 2014 Ebola outbreak in West Africa?How could the motives and motivation of Swedish medical personnel be categorized in accordance with the Volunteer Function Inventory (VFI)?Is the Volunteer Function Inventory (VFI) a sufficient tool for analyzing the motives and motivation of Swedish medical personnel in the given case?The presented research questions will be answer through a qualitative theory-consuming study, based mainly on interviews. The interviews are, however, complimented by various written sources in the field of research.The result and subsequent analysis confirms the authors? notion on the VFI and highlights certain deficits in the tool?s execution and its succeeding result.
Hard Decisons, Soft Laws : Exploring the authority and the political impact of soft law in international law
The question of whether there is soft law in international law has been as much the subject of contemporary debate as whether or not there is private legal authority in the international society. The legal boundaries seem to be blurred by the process of globalisation and the recent shift in international law. The traditional definition of international law has been outdated as new forms of treaties has introduced new subject of law to the judicial arena. At the same time a supplementary map of law has been added to the cartography of international law, soft law. These correlating processes have comprehensive political and legal consequences at both the international and national levels.
Trädföryngring i låga gropar uppkomna vid brand i boreal naturskog :
This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees.
In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.
Vårdberoende, behov av omvårdnad och insatser för äldre med regelbunden vård och omsorg ? del av SNAC-Blekinge, Vårdsystemdelen
Background: The relationship between advanced age, presence of illness and impaired functioning is well known. A large proportion of the elderly population has an extensive need of care and service and therefore need help from municipal care. Aging is a transition in life and also affects the person's identity and self image, making the person particularly vulnerable and challenging everyday safety. It is therefore of importance to gain knowledge about which factors at individual and organizational level that support a person-centered nursing care for the elderly so that caring responsibilities and staffing of nursing personnel may be scheduled based on need. Aim: This study aimed at describing dependency and care needs of elderly persons living in ordinary housing, sheltered housing and nursing homes.
Barns möjlighet att uttrycka sin åsikt : En kvantitativ aktstudie om barns närvaro inom socialtjänstens förhandsbedömningar
Syftet med denna studie är att söka svar på i vilken omfattning barn har getts möjlighet att uttrycka sin åsikt inom socialtjänstens förhandsbedömningar som inte har lett till utredning. Detta genom att mäta i vilken omfattning barnets närvaro har dokumenterats inom ramen för en förhandsbedömning som inte har lett till utredning. För att besvara studiens syfte användes utvalda variabler för att ta reda på om det finns eventuella omständigheter som kan ha påverkat om barnet har getts möjlighet att uttrycka sin åsikt. Barnets ställning inom socialtjänsten är stärkt på ett flertal vis och denna studie tar avstamp i vad socialtjänstlagen (SFS 2001:453), FN:s konvention om barnets rättigheter och Stockholms stads riktlinjer för socialtjänsten fastställer om barnets möjlighet till att uttrycka sin åsikt i ärenden som rör dess person. Studien är en kvantitativ aktstudie och empirin består av 384 förhandsbedömningar som inte lett till utredning. Förhandsbedömningarna är genomförda av samma stadsdel inom Stockholms stad under 2013.
Förekomst av Klebsiella pneumoniae i avföring hos mjölkkor : en riskfaktor för mastit?
Cows affected by mastitis caused by Klebsiella (K.) pneumoniae often become seriously ill. In some cases herdproblems may occur. Contaminated bedding material is considered to be one of the most common risk factors for klebsiella mastitis. In a recently performed study in USA it was found, however, that more than 80 % of healthy, lactating dairy cows excreted K. pneumoniae in faeces.
Undersökning av svetsegenskaper för svetsning med rörtråd kontra homogen tråd
Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.
Fenomenet Poppe, mellan scen och skratt : En studie av Nils Poppes komiska skådespeleri utifrån en fenomenologisk utgångspunkt
Scholarly research on comical popular theatre is rare in the Swedish context even though the genre has attracted large audiences throughout the 20th century. Nils Poppe is one of the greatest Swedish actors in the comical genre and he is famous for his playful acting style. With my Master?s dissertation I aim to shed some light on both the genre and this great actor. Another aim of this Master?s dissertation is to gain understanding of what causes the audience?s laughter experiencing Nils Poppe?s comical acting.
Rhododendron ur undersläktet Vireya - något om dess karakteristika och användning i nordiska vinterträdgårdar :
Present essay aims to introduce the reader to central topics regarding Rhododendrons of subgenus Vireya. As a result of a donation, the Swedish University of Agricultural Sciences, received a collection of Vireya from a local amateur grower, Kurt Myllenberg. Since the subgenus Vireya is uncommon in Scandinavian horticulture, the study tries to establish conditions for successful growing.
The subgenus Vireya differ from the other Rhododendron species through mainly three characteristics: the presence of two tails, attached to each end of the seed; the ovary-style junction is tapering and the pedicels arises directly from a dome-like base and form an umbel and not a raceme. The subgenus is distributed mostly in the islands of Indonesia and New Guinea, but also from Malaysia to Nepal and in Australia.
Since Vireya species mainly grows as epiphytes in the tree canopies, they need high drainage and not too much water.
En demokratisk organisation - ett klick bort? : En kvantitativ innehållsanalys som undersöker potential för demokratisk kommunikation via intranät
AbstractTitle: A democratic organisation - one click away? A quantitative content analysis which studies the potential of democratic communication through intranet use.Authors: Stina Gabrielsson and Jill Johansson VennelinPurpose: The purpose of this study was to investigate whether there is potential for democratic communication within the NGOs through intranet use.Key questions to be answered were: To what extent is authority versus members represented on the intranet Klick?s discussion forum? What/which communication-related functions out of social function, knowledge transferring and debate are featured in the posts published on the intranet Klick?s discussion forum? Are deliberative discussions being practiced in the discussion forumthreads on the intranet Klick? The thesis is based on the theory of deliberative democracy. In order to substantiate the theory has theoretical perspectives concerning participation and involvement also been applied. These perspectives are derived from organizational theory and internal communication.Method/Material: This study consists of a quantitative content analysis of the 477 posts and the 129 discussion threads available on the NGO RFSU?s intranet Klick the 29th of november 2012.Main results: The results show that 63, 4 percent of those who were active in the discussionforum represented the category authority, while the category members were formed by 36, 6 percent.

Aging is a transition in life and also affects the person's identity and self
image, making the person particularly vulnerable and challenging everyday
safety. It is therefore of importance to gain knowledge about which factors at
individual and organizational level that support a person-centered nursing care
for the elderly so that caring responsibilities and staffing of nursing
personnel may be scheduled based on need. Aim: This study aimed at describing
dependency and care needs of elderly persons living in ordinary housing,
sheltered housing and nursing homes. Furthermore the study aimed at describing
how the dependency was related to the staffing of non-licensed and licensed
nursing staff in nursing homes.
Method: A descriptive and analytical quantitative method was used in the study.
Hematologiska analysinstrument för mindre djurkliniker : en utvärdering av QBC-V och Scil Vet abc för analys av prover från hund och katt
Two haematological instruments intended for small animal clinic use were
evaluated at the Department of Clinical Chemistry, Swedish University of
Agricultural Sciences (SLU), Uppsala, Sweden. The QBC-V and Vet abc were
compared to a reference instrument, the Cell-Dyn 3500. Fresh blood samples were
obtained from canine and feline patients from the University Veterinary Hospital,
SLU. The QBC-V was used for 111 canine samples and 78 canine blood samples
were analysed with Vet abc. From cats, 23 samples were analysed with both
instruments.
Ulf Ekmans konversion till Katolska kyrkan i svensk dagspress : Diskussion utifrån ett diskursanalytiskt perspektiv
The purpose of this paper is to analyze the reasons a religious minority leader has to convert to a larger religious group and how the leader chooses to communicate this event in certain daily press. In March 2014 the leader and founder of the Christian and charismatic movement ?Livets Ord? (Words of Life), Ulf Ekman, announced his decision converting to the Roman Catholic Church after a 10 year long process of thinking. The communications of Ekman?s linguistic language in the articles are discussed through two discourse analyzing perspective, Laclau & Mouffe?s and Fairclough?s.
