Phytase is used as a feed additive for degradation of antinutritional phytate, and the enzyme is desired to be highly thermostable for it to withstand feed formulation conditions. A Bacillus sp. MD2 showing phytase activity was isolated, and the phytase encoding gene was cloned and expressed in Escherichia coli. The recombinant phytase exhibited high stability at temperatures up to 100 degrees C.
Background: Ability to manage urges to smoke is fundamental to maximizing the chances of success in smoking cessation. Previous studies have linked a higher dose of nicotine in nicotine replacement therapy to a higher success rate for smoking cessation. Thus, this study was performed to compare relief of urges to smoke, up until 5 h following treatment with a new 6 mg nicotine gum versus currently
The inorganic metal or metal-oxide nanoparticles (NPs) that mimic enzymes are of great interest due to improved physical and chemical properties compared with native enzymes. Here, we report that manganese dioxide (MnO2)-Silk exhibit catalase, oxidase, and peroxidase-like activities. The MnO2-Silk hybrid fibers effectively decomposed hydrogen peroxide (H2O2) and oxidized the typical horseradish pe
Most freight wagons in the EU use cast iron brake blocks. Cast iron brake blocks have a stable braking capability in different environmental conditions, but wear down the wheel tread quickly. Therefore, there is a need to understand the tribology of other brake block materials. A pin-on-disc tribometer placed in a temperature-controlled chamber is used to investigate the tribology of cast iron, si
Industrial symbiosis (IS) is a key paradigm for achieving circular economy among industrial firms. Achieving new IS projects often requires outside facilitation, and intermediaries can help solidify and expand existing IS networks. While various intermediary roles have been identified in the literature, less attention has been paid to the potential challenges that intermediaries might encounter in
According to the Global Burden of Disease study, occupational exposures to particulates, gases and fumes were responsible for 0.36 million deaths and 8.8 million disability-adjusted life years globally in 2015. This thesis focuses on two occupational groups that are at risk for developing adverse health effects from the time they spend in their working environments: cleaning workers and workers in
The objective was to investigate if diffusing laser fibres can be modelled as conductive heat sources without miscalculating coagulated volumes, and if finite element analysis, disregarding light transport, may be used for three dimensional (3D) treatment planning in interstitial laser thermotherapy (ILT). Temperature distributions and coagulated volumes with a diffusing laser fibre, as compared t
Regional blood flow in rat liver and in inoculated liver tumors was studied before, during and after local hyperthermia treatment at 42.0°C for one hour. Hyperthermia was induced by microwave irradiation of the central liver lobe. The method used for blood flow studies was the clearance of Xenon-133 following portal and intraparenchymal injection. The wash-out curves were analyzed by using a bi-ex
Soil mineral weathering is one of the major sources of base cations (BC), which play a dual role in forest ecosystems: they function as plant nutrients and buffer against the acidification of catchment runoff. On a long-term basis, soil weathering rates determine the highest sustainable forest productivity that does not cause acidification. It is believed that the hydrologic residence time plays a
Högestad utgör, med sina ca 13 000 ha, en del av Skånes största enskilda egendom med verksamhet inom jordbruk och skogsbruk, viltvård och fasigheter. Under våren 2006 inleddes ett samarbete mellan Högestad och Lunds universitet för en långsiktig hållbar utveckling. En del i samarbetet utgörs av tillgängligare information gällande forskningsresultat av t.ex. klimatförändringens påverkan av jordbrukHögestad is with an area of 13 000 ha one of the largest landowners in the southern part of Sweden (Skåne). In spring 2006, the collaboration between Högestad and Lund University for a long-term sustainable development was initiated. This collaboration comprises the easy access and transfer of information about new research results. These results include the effect of climate change on agriculture
I denna uppsats undersöks rättsläget för arbetstagares yttrandefrihet och gränserna för kritikrätten vid användning av sociala medier såsom Facebook och bloggar. Arbetstagaren har en plikt att vara lojal gentemot sin arbetsgivare. Lojalitetsplikten utgör en samlingsbeteckning för en rad olika förpliktelser, t.ex. tystnadsplikten och den närliggande skyldigheten att iaktta begränsning i kritikrätteIn this thesis the employees’ freedom of expression and right to criticize the employer when using social media such as Facebook and blogs is examined. The employee has an obligation to be loyal to his or her employer. The concept of loyalty covers many different obligations, for example the duty to respect confidentiality and the closely related duty to not criticize the employer, the employer’s
Populärvetenskaplig sammanfattning: De kvartära landskapsformerna i södra Sverige skapades till stor del under och i samband med avsmältningen av den senaste inlandesisen. Skåne blev isfritt för ca 13 000 år sedan med en isavsmältning i nordvästar Skåne mot NO. I samband med denna avsmältning skapades ett småkuperat moränlandskap, plana slätter, mindre kullar och åsar. Åsarna har bildats av materiThe purpose with this study is to identify and examine heterogeneities within the ground, which is important for the groundwater flow on a more local scale. Investigation of the geology within an area is normally done through observations in field, combined with studies of geological maps and documented drillings. Depending on drilling methods, varying results are obtained but often with a good re
Denna kvalitativa intervjustudie söker svar på frågan hur rehabiliteringsarbetet med kommunalanställda som är långtidssjukskrivna på grund av mental ohälsa i Burlövs Kommun fungerar. Detta arbete sker i samverkan mellan flera aktörer och studeras därför som ett projekt där de olika aktörerna utgör projektets deltagare. Det empiriska materialet analyseras med hjälp av de teoretiska analysverktygen
PURPOSE: A meta-analysis was performed to compare the rates of the major complications associated with two gastrostomy tube placement techniques in a pediatric population: laparoscopy-assisted gastrostomy (LAG) and percutaneous endoscopic gastrostomy (PEG).METHODS: The PubMed electronic database was queried for comparative studies of the two insertion techniques. The Newcastle-Ottawa scale (NOS) w
Populärvetenskaplig sammanfattning: Rassepautasjtjåkka är ett litet bergsmassiv beläget i norra Lappland. I massivet återfinns fyra stora nischer strax under glaciationsgränsen. Dessa nischer har en gång blivit uteroderade av glaciärer, men idag återfinns endast perenna snölegor i området. Skillnaden mellan en glaciär och en perenn snölega är att en glaciär har intern rörelse. En tjocklek på cirkaSince the mid 1970s the general retreating trend for glacier in Scandinavian have ceased and some glaciers have even started to advance. This is due to a more maritime influence on the climate, which means increased precipitation in winter and lower summer temperature. A more maritime climate can be said to be favourable for glacier growth. Under such climate conditions is it possible that new gla
Abstract Uppsatsen behandlar ämnena organiatorisk förändring samt varumärkesladding. Även identitet, profil och image diskuteras. I arbetet har vi använt oss av Lindex som fallföretag. Omladdning av ett varumärke blir aktuellt när märkets brand equity stagnerat eller när företag önskar förändra de värden som är kopplade till varumärket. Detta tillsammans med en organisatorisk förändring har varit
Sweden has a very favourable legislation regarding paid parental leave. However, in the labour market this is not always something positive. Absence from the workplace, and especially a long one, may disturb the employer's organisation and there is a risk that employers compensate for this by, in the worst case, avoiding to employ workers of a fertile age. Further, back at the workplace after
