Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers

Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol. This thesis contains studies with the aim to improve the enzymatic hydrolysis of cellulose from steam pretreated spru

Comparative optics of prosobranch eyes

Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp. from heavily vegetated habitats in tropical fresh-water. Littorina a

No title

The dissertation deals with two part-studies. The main focus is a field study the purpose of which is to understand incurable disease and death as hands-on experiences at the player's level. With the aid of observations and interviews, nine dying people, relatives and community nurses are followed in the families? homes over time. The second part-study is a discourse analysis of Danish health-poli

Understanding Weather effects on, in, and from large Herbivore Population Dynamics

Large herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. Nevertheless, data in the less detailed form of annual censuses of large herbivore densities and weather i

Aspects of Morphological and Stylistic Variation of the Verb in Erotokritos

The aim of the present study is to examine the polytypia (morphological variation) and semantic differentiations of the verb in Vitsentzos Kornaros' Erotokritos, to understand how these shape poetic style. We examine the stems and the endings in the imperfective active forms. Moreover, we investigate the augmented forms because at an early stage we found that Kornaros employs a degree of poetic li

Järnålderns Skåne : samhälle, centra och regioner

The first purpose of this dissertation is to describe and discuss the development of the Iron Age society in Scania. The second purpose is to discuss the relations between Scania and the neighbouring areas. The Iron Age society was hierarchical and ruled by different types of leaders, usually cheiftains or kings. To maintain and develop the social system different social groups acted in society.

Towards Quantitative Diagnostics using Short-Pulse Laser Techniques

Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena th

Som vem som helst : Kön, funktionalitet och idrottande kroppar

The main aim of this thesis is to explore young women’s lived experience of the body, which, on one hand, is viewed as deviant – the disabled body – and, on the other hand, is viewed as accomplished – the sporting body. The questions posed in the thesis are the following: how do the young women handle the two subject positions that emerge as a result of the perception of them as respectively devia

BMP treatment for improving tendon repair. Studies on rat and rabbit Achilles tendons

We wanted to improve tendon healing by adding a growth factor. Bone Morphogenetic Proteins (BMPs) are well known to stimulate bone healing and bone formation. The local environment is of major importance for cell differentiation after a BMP has been added. Cartilage Derived Morphogenetic Proteins (CDMPs) -1, -2 and -3 (BMP 14, 13 and 12 or GDF 5, 6 and 7) form a subgroup in the BMP-family and are

Simulations of Transport Phenomena and Porous Structures Using Dissipative Particle Dynamics

The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. Mass transfer has also been studied in the membrane. Heat and mass transfer has been studied in parallel plate channels, first in saturated ch

Laurence-Moon-Bardet-Biedl syndrome. Clinical,electrophysiological and genetic aspects.

The study included 44 Scandinavian individuals with the autosomal recessive inherited Laurence-Moon-Bardet-Biedl syndrome. Inclusion criteria were retinal dystrophy plus at least 2 more of the remaining traditional cardinal signs of the syndrome: obesity, polydactyly, hypogenitalism and mental retardation. The study showed that the patients had an early onset of night blindness and a poor visual p

Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. Two different detectors ’ Design A and Design B’ were fabricated with thi

Water Management BIOR66

15 credits This course aims to integrate theoretical knowledge within aquatic ecology and hydrology to be used within practical water management.  In this applied course, through a combination of lectures, practical training, seminars, group projects, field trips and study visits, you will obtain a thorough knowledge of the areas that you are supposed to master when working within water management

Introducing a Clinically Applicable Ultrasound Method for the Study of Gastric Emptying in Health and Disease. A Study in Healthy Subjects and Patients with Diabetes Mellitus

Abnormal gastric motor function, a frequent complication among the increasing diabetic population of the world, also includes other patient groups such as those many patients with functional dyspepsia. These facts stress the need for a reliable, safe, cost-effective, and simple technique for measuring gastric emptying. To date the ultrasound technique for measuring gastric emptying has been regard

Terrestrial Ecosystem Interactions with Global Climate and Socio-Economics

The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. Currently it is responsible for removing 25-30% of our emissions every year, an important ecosystem service that may not persist in the long term. Global warming tends to decrease the CO2 sink capacity of the world’s oceans and ecosystems leading to a larger fraction of our emiss

About the museum

Natural history museums are fundamental for understanding life on Earth as we undergo unprecedented loss of biodiversity and climate change through the actions of humans. With more than 250 years of records, the Biological Museum at Lund University plays a central role in research on the biodiversity crisis as well as the effects of climate change on our fauna and flora.  Our collections hold abou

Eating Habits and Planetary Health

The global food system accounts for 21-34% of total greenhouse gas emissions and is one of the strongest drivers of biodiversity loss. Neither the SDGs, nor the Paris Climate agreement, can be met without a radical transformation within all stages of the food system. The scientific community suggests several necessary changes to promote human health and prosperity while preserving the health of Ea
