Membrane extraction techniques permit the application of classical liquid-liquid extraction (LLE) chemistry to instrumental and automated operation. Various shortcomings of LLE are overcome by membrane extraction techniques as they use none or very little organic solvents, high enrichment factors can be obtained and there are no problems with emulsions. A three phase SLM system (aq/org/aq), where
A model of an industrial through-dryer for production of tissue paper was developed. The model can be used to predict the performance of a dryer section of an industrial through-drying machine consisting of one or more through-drying rolls separated by free draw sections. Roll diameters, wrap angles, machine speed, basis weight, initial paper moisture ratio, operating pressure differentials, dryin
Frequency Measures in AF. Introduction: Frequency analysis of fibrillation (FAF) and time-frequency analysis (TFA) were developed recently in order to quantify atrial electrical remodeling in atrial fibrillation (AF) from the surface ECG. This article describes the experience with these two different frequency analysis techniques in consecutive AF patients and discusses possible applications in AF
High-profile bribery scandals that involve powerful people and large sums of money are often the object of general indignation and legal action. When it comes to bribery of the everyday kind, however, it is far less obvious which gifts should be seen as bribes, be it in a moral or legal sense. Legal cases of this kind almost always include voices that strive to refute accusations of bribery. This
Lund University, Sweden, is the only seat of learning having Sociology of Law (hereafter SoL) at all levels in Europe. SoL was initiated in 1972 as a department at the Social Science Faculty, with professor Per Stjernquist as chair. Later on, for some 10 years, SoL was a division within the department of Sociology but from January 2006, SoL is an autonomous department at the Social Science Faculty
Proteins are composed of 20 different amino acids. In the translation process, each of these 20 amino acids is specifically recognized by their cognate aminoacyl-tRNA synthetase. The fidelity of this recognition system is essential if translation is to function properly. The development of an in vitro system based on this recognition scheme would make a powerful analytical tool with which to analy
Earnings assimilation is the process of convergence between the wages of e.g. women and men or a native and an immigrant. Frequently people refer to earnings assimilation as a way to look into the level of integration of an individual. But it is important to note that the fact that a person earns as much as the one that surround them or even above the average does not mean that he or she is integr
Title: Health in developing countries – The determinants of health in Latin American and Caribbean countries Author: Fredrik Klintberg Supervisor: Carl Hampus Lyttkens, Professor, Department of Economics, School of Economics and Management, Lund University Problem discussion: There are still today many problems related to health in developing countries. When reasoning on how to deal with these pro
Scientific abstract: As the increasing attentions drawn to the environment and climate change issue, the profound impact on the earth system made known to nearly every corner of the world. A great variety of global protocols and conventions has been established aiming to reduce global environmental risks and maintain a healthy earth system. In order to monitor, supervise these protocols and conven
Agroforestry är ett jordbrukssystem där odling av grödor kombineras med träd på samma jordbruksytor. Då den stadigt minskande markbördigheten ses som den främsta begränsningen till ökade skördar, är det nödvändigt för en hållbar matproduktion att näringsämnen som tas upp av grödor från marken, eller försvinner på grund av erosion och urlakning, fylls på. Många länder i Afrika har i flera årtiondenAgroforestry is an agricultural system where crop farming is combined with trees on the same land. The steadily decreasing soil fertility is considered to be the primary constraint to increased crop yields, and it is vital to replenish the nutrients lost by plant uptake or removal by erosion and leaching for a sustainable food production. Several African countries have for tens of years received f
Popular Abstract in Swedish Avhandlingens syfte är att söka kunskap om vilka faktorer som bidrar till uppfostringsanstaltens framgång som social institution och dess ständiga misslyckande som behandlingsorganisation. Jag försöker förstå varför organisationer som §12-hem och särskilda ungdomshem finns och vilken betydelse de har i vårt samhälle. Svaret på den frågan söker jag på tre sätt: genom attThe aim of the present study is to find the factors and conditions that generate the success of the reformatory as a social institution and, at the same time, its well-known failure as a treatment organization. I try to understand why organizations like the reformatory exist and what meaning they have in our society. I seek answers by exploring the birth of the reformatory in a historical perspect
Orientation for insects in olfactory landscapes with high semiochemical diversity may be a challenging task. The partitioning of odor plumes into filaments that are interspersed with pockets of ‘clean air’ may help filament discrimination and upwind flight to attractive sources in the face of inhibitory signals. We studied the effect of distance between odor sources on trap catches of the beetle,
In order to achieve the goal of sustainable banking, banks such as commercial banks have to adopt proactive strategies for reducing internal operation risks from environmental issues thereby realizing long-term profitability by external financing of environmentally friendly products and services. As a general pathway to sustainable banking, environmental risk management (ERM) is regarded as a prev
This PhD thesis examines how application of 3D visualization and related digital analytical tools is having a transformative impact on archaeological practice via improvement of visual-spatial thinking and the strengthening of conceptual understanding. However, the deployment of these new digital methods is essentially still at an experimental stage. Therefore, the thesis undertakes a critical eva
The discovery of ferroelectricity in CMOS-compatible oxides, such as doped hafnium oxide, has opened new possibilities for electronics by reviving the use of ferroelectric implementations on modern technology platforms. This thesis presents the ground-up integration of ferroelectric HfO2 on a thermally sensitive III-V nanowire platform leading to the successful implementation of ferroelectric tran
Introduction Tourette syndrome and chronic tic disorder are common, disabling childhood-onset conditions. Guidelines recommend that behavioural therapy should be offered as first-line treatment for children with tics. However, there are very few trained behaviour therapists for tics and many patients cannot access appropriate care. This trial investigates whether an internet-delivered intervention
Purpose – The purpose of this paper is to explore in what way gradually increasing teachers’ theory-based instruction affects the students’ learning outcomes, illustrated by the example of learning how to regulate body tension in the upper secondary school. Design/methodology/approach – In total, 72 students from four classes participated in the study. The way the students were offered to understa
This thesis reports on the research undertaken to increase the sustainability of foodmanufacturing by reducing the solid Food waste generation, as well as Energy and Water(FEW) consumptions through applications based of Internet of Things (IoT) concepts. Theprimary objective of this research is to develop an IoT-based framework, which identifies andcollects the key data regarding FEW within food m
