This thesis describes the characterization of the rheological properties of dense suspensions of sodium caseinate and micellar casein with respect to changes in concentration (100-200g/L), pH (7.0-5.3), charge density (Δα), and temperature (5-40°C). The relationship between pH and charge density and how this relationship is affected by changes in temperature and concentration were also addressed.

Uppsatsen behandlar den tekniska konsultens ansvar när standardavtalet ABK 09 är tillämpligt. ABK 09 är ett standardavtal som är avsett att tilläm-pas vid konsultuppdrag inom arkitekt- och ingenjörsverksamhet. Den hu-vudsakliga frågan som behandlas i uppsatsen är vad det innebär att konsul-ten ska genomföra uppdraget fackmässigt, med omsorg och i enlighet med god yrkessed. Att konsulten ska genomfThe paper deals with the technical consultant’s responsibility in a contractu-al relationship when the standard agreement ABK 09 is applicable. ABK 09 is a standard agreement that is intended for commissions within architecture and engineering. The main issue in the essay is what it means that the con-sultant shall execute the commission professionally, with care and in ac-cordance with profession
The purpose of this study was to gain a greater understanding on how healthcare workers, particularly caregivers of elderly and dementia patients, are impacted by a Mindfulness-based Stress Reduction (MBSR) training and to explore the reasons a manager has for incorporating these types of trainings. Within the scope of this qualitative study, we conducted semi-structured interviews with nine careg
The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. This to investigate the content of the fuel-containing capsules, primarily to ensure non-proliferation of radioactive materials in the nuclear waste
The aim of this thesis is to identify the roots of the leftover women phenomenon in order to understand why it has appeared. In particular, we examine why the leftover women are having difficulties in finding a husband in the Chinese marriage market. Additionally, we establish whether the leftover women phenomenon may be a consequence of the increasing patriarchal norms in China. Through an in-dep
In the Dominican Republic, residing Haitians and their descendants, emigrated from the neighboring country Haiti, occupy the lowest societal strata. A societal position ascribed to the long and fraught history between the two countries. Their presence has for decades caused great aversion and has officially been labeled anti-Haitianism. Described as a viable political tool for conservatives and na
Uppsatsen undersöker egenutgivning ur författarnas perspektiv för att se hur de själva upplever sin verksamhet, vad som driver dem och vilka hinder de möter i samband med sin bokutgivning. Materialet består av en enkätundersökning samt intervjuer med egenutgivare, vilket huvudsakligen analyseras med hjälp av John B. Thompsons teorier om aktörers kapital samt länkar i publiceringskedjan. Resultatet
This thesis explores political systems of divided societies with the emphasis on democratic principles, hence its influence on fundamental elements for establishing a stable state. To demonstrate such system, this case study sheds light on a desperate situation of a forgotten country in southeastern Europe, once recognized for being a strong state and home for the population carrying different eth
The growing trend in organic consumption has lead us to develop a research about barriers that influences young consumer’s beliefs and attitudes toward organic food. The study is based on results of a survey conducted in a supermarket from Malmo on a sample of 270 occasional and non-organic young consumers aged 18-36 years. The data collected was analyzed with SPSS 23.0 by carrying out hierarchica
A sample with five Nanowire Solar Cell (NWSC) devices of equal design were performance evaluated by characterizing the current spatially and by investigating the angular and polarization dependence. For spatial characterization a Scanning Photocurrent Microscopy (SPCM) setup was developed using a highly focused laser which is scanned across the device as the photocurrent is measured. The photocur
The I-V and photovoltaic properties of III-V semiconducting GaInP nanowires have been studied using a scanning tunneling microscope (STM) in evaluation for usage as a potential "sub cell" in a nanowire based tandem solar cell configuration. This evaluation required precise I-V characterization and photo response measurements of individual nanowires. Such measurements usually involve rigo
Idag dimensioneras konstruktioner dels för permanenta laster såsom egentyngd, dels för variabla laster i form av snölast, vindlast och nyttig last. Mot bakgrund av pågående klimatförändringar och kraftiga regnoväder på senare år, exempelvis i Malmö hösten 2014, kan även vattenlaster få en större betydelse i framtiden. I synnerhet på låglutande och flacka tak finns det risk för betydande mängder kv
In this work, inverse diffusion equation and Monte Carlo methods are used in conjunction with diffuse reflectance spectroscopy to develop a protocol for evaluating the chromophore compositions of tissue mimicking liquid phantoms. A novel two spectrometer system is used which provides real time calibration of any intensity fluctuations of the light source. The calibration of this setup is investiga
This study aims to investigate and explain the portrayal of refugees in Swedish media, and to use the media as a way of understanding society at large. The analysis is based on newspaper articles written during times when nationalist parties have been in parliament in Sweden, the periods being 1990 to 1995 and 2010 to 2015. By looking at how the media portrays and reports on refugees through the t
Background. Lack of knowledge why consumers carry out unsustainable fashion practices inspired the following thesis to explore the phenomenon from a socio-cultural perspective. Although previous studies in green consumption explored to some extent how and why people consume green products, the research in the field is still underdeveloped. An extensive literature review demonstrated a limited unde
För att klimatförändringarna inte ska bli för stora har Sverige som mål att till år 2020 reducera utsläppen av växthusgaser med 40%. För att klara detta arbete behöver Sveriges kommuner hjälpa till med lokala mål och åtgärder, och Ängelholms kommun har då valt att i sin miljöplan bestämma att kommunen år 2021 ska vara helt fossilbränslefria i alla transporter som kommunen äger eller brukar. SyftetSweden has a goal to reduce the emissions of greenhouse gases with 40 % until 2020 to prevent the climate change from becoming too big. Too succeed in this work, the Swedish municipalities need to help with local goals and arrangements. The municipality of Ängelholm has chosen to decide in its environmental action plan that the municipality by 2021 is going to be completely free of fossil fuels in
Comparing with traditional linear regression methods that used to monitor vegetation trends, a nonlinear regression algorithm (PolyTrend) developed by Jamali et al. (2014) can provide more accurate information of vegetation trends by fitting a polynomial line with a degree of up to three for ASCII-formed time-series NDVI (Normalized Difference Vegetation Index) dataset of a single pixel. To extend
Planar antennae have become very popular owing to their relative ease of manufacture and unobtrusive nature (they are conformal to surfaces) especially with regard to certain devices such as smart phones, watches and fitness gadgets. Although the fractional bandwidth of planar antennae is small, the actual bandwidth in absolute terms is high owing to the higher centre frequencies used and proves u
This Master Thesis was performed for Sandvik SRP in collaboration with the Institution for Industrial Production Faculty of Engineering at Lund University. Tool wear is one of the main cost drivers in the mining industry. By being able to characterize what kind of rock involved, you can choose a more beneficial tool material to minimize the wear and thereby reduce the maintenance costs. The purpos
