Adsorption onto hydrophobic surfaces of α-, β-, γ-, and ω-gliadins from the wheat variety Chinese Spring was studied by means of in situ ellipsometry. Most measurements were conducted in 0·01m phosphate buffer, pH 6·0, with the protein concentrations 1, 5 and 25 μg/mL. The adsorbed amount varied between 1·3 and 11·4 mg/m2, which is high considering the low protein concentrations. The concentration
The adsorption of β-lactoglobulin to stainless steel and its subsequent alkali-induced removal were followed using ellipsometry. New steel samples differing in bulk composition, surface finish or chemical pretreatment were used. All surfaces were precleaned in strongly alkaline solution, and some were subsequently passivated in nitric acid. Furthermore, on surfaces differing in pretreatment measur
Ellipsometry and radio-labelling techniques were employed to study the deposition of human serum albumin (HSA) followed by excess of mono- or polyclonal anti-HSA to methylated silicon. Adsorbed HSA, and [HSA-monoclonal anti-HSA] layers were rapidly removed by 0.1-0.5% SDS, but [HSA-polyclonal anti-HSA] layers were not. The results suggest that antigens and polyclonal antibodies crosslink on surfac
The adsorption of β-lactoglobulin onto methylated silica surfaces and the subsequent protein removal by the anionic surfactant sodium dodecyl sulphate (SDS) were followed using in-situ ellipsometry. Experiments were performed at pH 6.0 in phosphate-buffered saline solution. Parameters varied include temperature, length of time for protein adsorption from solution and surface residence time of β-la
Particle-stabilized emulsions, called Pickering emulsions, can be produced by using starch particles. In this work we studied how the properties of the starch particles affect the droplet size and creaming of such emulsions. In the study, various sizes of starch particles were generated by two different methods and used to stabilize Pickering emulsions. Sedimentation according to Stokes’ law was u
Epstein-Barr virus (EBV) is a potent inducer of polyclonal B lymphocyte proliferation and is widely used as a tool for the establishment of B cell lines producing human monoclonal antibodies. However, because of low transformability, low clonability, and the inherent instability of EBV-infected B cells, valuable antibody-producing B cells are often lost during this procedure. We have here examined
Background: Cholera as an endemic disease remains a health issue in Iran despite decrease in incidence. Since forecasting epidemic diseases provides appropriate preventive actions in disease spread, different forecasting methods including artificial neural networks have been developed to study parameters involved in incidence and spread of epidemic diseases such as cholera.Objectives: In this stud
Context: Somatostatin inhibits a range of hormones, including GH, insulin, and glucagon, but little is known about its role in the development of cardiometabolic disease. Objective: The objective of the study was to investigate whether fasting plasma concentration of N-terminal prosomatostatin (NT-proSST) is associated with the development of diabetes, coronary artery disease (CAD), and mortality.
This study explores employees' experiences and management strategies during a corporate restructuring process in a small organization. The purpose is to analyze how the restructuring process impacts employees' emotional reactions, work morale, and loyalty, as well as how management has handled uncertainty and communication to support employees. The study employs a qualitative method, using
The Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
Since 1994 super-resolution microscopes enable us to visualize processes in the nanome- ter regime where bio-molecules work. Consequently, there is a great need for methods analyzing the generated data to transfer the motion of molecules, seen as white dots, into trajectories. Important steps in understanding bio-molecular behavior are first the detection of those and then generating trajectories
This thesis research analyses the role of local and regional governance in fostering the circular economy, using Uusimaa and Päijät-Häme – both being regions in Finland – as study cases. The main inquiry is to understand the role along the seven causal factors that were identified as relevant for this study, which are captured by the notions of i) interpretation and congruence of the circular econ
The study of home has historically been approached by numerous academic disciplines within the social sciences and humanities. However, increased international mobility and forced migration due to conflict in recent years has produced a renewed interest to understand the ways we conceptualize and (re)create home in foreign places. The present research aims to produce a theoretical framework that a
This paper explores the use of an automated pipeline to construct synthetic (artificially derived) trip data from aggregate socio-demographic sources to build a simulation of individual vehicles interacting with one another. The study shows that quality data sources are required in order to do this effectively and accurately. It is shown that aspects of typical patterns and behaviours may still n
The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctu
Title: A Comparative analysis of the design and use of performance measurement in two Universities - Lund University and Liepaja University Seminar date: May 2017 Course: BUSN79 Business Administration Degree Project in Accounting and Finance, 15 credits Authors: Kaspars Sokolovskis & Liwaalislam Joudeh Supervisor: Anna Glenngård Keywords: Management control, performance measurement systems, p
Loss of biodiversity is an immediate threat to the planet and if no actions are taken it is expected to accelerate. The highest species richness on smaller scale is found in semi-natural temperate grasslands, with one of the documented records from Stora Alvaret on Öland, Sweden. The area is protected under the Natura 2000-network and Länstyrelsen Kalmar are responsible for monitoring while local
Hollow fiber supported liquid membrane sampling and speciation of lead(II) from aqueous solution using a selective carrier (Kelex 100) is studied. An optimization of different variables affecting permeation performance (chemical conditions of the sampling module - pH, concentration and nature of the acceptor phase, extractant concentration; membrane impregnation form; sampling time; and hollow fib
