Cleavage of DNA using plant hemoglobins

Three non-symbiotic hemoglobins (nsHb) have been identified in Beta Vulgaris (sugar beet). These are hexacoordinated Hbs with high oxygen affinity. The spectral properties for one of these, BvHb1.1 was analyzed and its molar absorption coefficients determined. Furthermore, an initial safety analysis was carried out by studying the cleavage of plasmid DNA (pDNA) induced by these proteins. The resul

Kundorientering i patentprocesserna

Bakgrund: Det har skett en förändrad marknadsmiljö hos patentbyråerna idag, i alla fall för de större byråerna. Förr agerade patentbyråerna mer som ordermottagare, efterfrågan var stor i förhållande till antalet aktörer på marknaden. Vilket gav patentkonsulterna en starkare position i förhandlingarna med kunder. Detta har förändrats, på senare tid har det krävts mer arbete från patentkonsulter

Grönlutslam för efterbehandling av gruvavfall

Bakgrund Vid gruvdrift uppstår miljöfarligt avfall i form av gråberg som innehåller metaller som kan urlakas. Avfallet kan oskadliggöras genom att lägga ut tät morän som ett vattenhållande tätskikt kring gråbergsupplaget. Transportkostnaderna för detta är oftast höga då morän av tillräcklig kvalitet måste hämtas långt ifrån upplagen. Studier har visat att kvaliteten på morän kan förbättras genom a

Simulation and data analysis of peer-to-peer traffic for live video streaming

Evaluating and testing changes or configurations to peer-to-peer systems or even understanding their behaviour can be complicated. One approach is to simulate a large peer-to-peer system and visualise the results. In this master's thesis a study is performed to understand how an actual implementation of a hybrid peer-to-peer live video streaming system behaves and performs under different scen

Integration of a Digital Built-in Self-Test for On-Chip Memories

The ability of testing on-chip circuitry is extremely essential to ASIC implemen- tations today. However, providing functional tests and verification for on-chip (embedded) memories always poses a huge number of challenges to the designer. Therefore, a co-existing automated built-in self-test block with the Design Under Test (DUT) seems crucial to provide comprehensive, efficient and robust testi

American Dream Turns to Nightmare: The Decline of the United States Middle Class

The United States middle class has become a major topic of discussion and debate over the past several years, playing an intricate part in economic and political policies today. The reasoning behind this is due to the acknowledgement of the average American household struggling to maintain their standard of living with rising costs of goods and services along with stagnating wages. Unemployment is

Efterarv och försäkring - Kan ett förmånstagarförordnande skapa ett efterarv?

Då en make ärver en make med släktingar i första eller andra parantelen uppstår arvsrättsligt en efterarvsrätt. Denna efterarvsrätt har tidigare inte förtydligat huruvida en försäkringsersättning som utfaller genom förmånstagarförordnande till efterlevande make ska inräknas i efterarvet. 1975 kom ett rättsfall från högsta domstolen som fastställde just detta, att det faktiskt föreligger rätt till When a spouse inherits another spouse, who has children from a previous marriage, parents, siblings or nephews alive, a right to secondary inheritance occurs according to Swedish law. Before 1975, it was not clarified whether this right to secondary inheritance should include an insurance reimburse-ment due to an insurance with a spouse as beneficiary. In 1975 the Swedish Supreme Court ruled that

Benefits and risks of implementing a dynamic shelf life prediction system

Matsvinn är ett problem med miljömässiga, ekonomiska och sociala konsekvenser. Nära en tredjedel av maten som produceras i världen idag kastas eller förstörs, något som är ohållbart av en mängd anledningar. Ett forskningsprojekt som drivs för att åtgärda detta är DynahMat-projektet på Lunds Universitet. DynahMat föreslår användandet av temperaturindikatorer och andra sensorer för att beräkna en prFood waste is a problem with environmental, economic and societal aspects.

Feedforward neural networks with ReLU activation functions are linear splines

In this thesis the approximation properties of feedforward articial neural networks with one hidden layer and ReLU activation functions are examined. It is shown that functions of these kind are linear splines and the number of spline knots depend on the number of nodes in the network. In fact an upper bound can be derived for the number of knots. Furthermore, the positioning of the knots depend o

Electrical Characterization of GaN Device Structures and Coalesced Films

Wide band gap semiconductors such as gallium nitride (GaN) are attractive candidates for short wavelength optoelectronic devices and high-power/high-temperature electronics. Widespread commercial adoption has been hindered by great difficulties encountered in obtaining high-quality materials. No suitable substrate material is available, making lattice matching unattainable and resulting in high th

Does repetition make perfect? Comparing scanpaths over repeated visual search to investigate how scanpath similarity evolves with experience

Visual search efficiency improves with repeated exposure to the same search problem, yet the mechanisms behind these search efficiency gains remain unclear. Investigating how eye-movement sequences evolve over repeated viewings is fundamental for understanding how skilful search develops over time and its role in learning and gaining expertise. Scanpath theory holds that repeated displays are inve
