Continuous analysis of waveform relaxation for heterogeneous heat equations Philipp Birken[0000−0002−6706−3634] and Martin J. Gander[0000−0001−8450−9223] and Niklas Kotarsky[0009−0001−5135−3776] 1 Introduction We consider the coupling of time dependent partial differential equations (PDEs) across an interface. This can be used to describe the exchange of heat or of forces be- tween different domai

Hematopoietic stem cells (HSC), the ancestors of all blood cells, have the ability to give rise to mature effector cells through a series of developmental steps. This is a tightly regulated, though a highly dynamic process: on the one hand, dysregulation in steady-state could lead to under- or overgrowth of certain blood cell lineages, whereas, on the other hand, demands for certain mature blood c

My PhD dissertation investigates relationships between contemporary art and spatial practices It emphasising the creation of platforms for public participation as interventions into urban regeneration processes. The project has two essential objectives: a. To identify the potential within contemporary art for a critical analysis of an urban de velopment process from the location, in dialogue with

Problem definition: In recent years, Kalmar has received an increased number of requests and indications from the market concerning automated solutions in the industry. In the paper industry this is mainly caused by the increased costs in the customer's key processes that possibly could be reduced by fully automated solutions. However, there is currently no clear view of the market potential a

Background In a competitive market place a competing company has to focus on continuous improvements and effectiveness, something that can be achieved by investing in product resources which then generates a need of capital. The need of capital can be financed through direct financing or external financing such as leasing where the leasing company offers the customer capital support. Since 1999, A

Treaties are the most important source of international law, but treaties are only binding when in force, and only with respect to the nations that have expressly agreed to become parties to them. The Vienna Convention on the Law of Treaties, from 1969, is the ''treaty on treaties''. The rules on reservations in the Vienna Convention, articles 19 to 23, govern the situation where p

Kortspelet poker har tagit världen med storm under 2000-talet. Utvecklingen har gått oerhört fort, bland annat tack vare TV och Internet. Idag kan i princip vem som helst som är över 18 år med ett kreditkort och tillgång till Internet skapa ett konto på en nätpokersida och inom några minuter möta spelare från hela världen på alla tänkbara insatsnivåer. Pokern har historiskt sett ofta förknippats m

Infatuation and love are two words associated with marriage, but from a historical perspective marriage has nothing to do with love. Marriage has been regulated by both religious and secular rules since medieval times. At first marriage was most common in wealthy families but with the involvement of the church marriage became a sacrament and something every good Christian had to commit to unless t

Av artikel 6 Europakonventionen följer att varje person som befinner sig under en medlemsstats jurisdiktion har rätt till en rättvis rättegång. Till de rättigheter som i detta avseende följer tillkommer bland annat oskyldighetspresumtionen som medför att varje person som står anklagad för brott försäkras att betraktas som oskyldig till att motsatsen bevisas och dennes skuld lagligen fastställts. OArticle 6 in the European Convention on Human Right provides that every person under the jurisdiction of a member state has the right to a fair trial. To the rights that follow in this respect are added, among other things, the presumption of innocence, which means that every person accused of a crime is assured to be considered innocent until proven guilty and his guilt legally establishes.

Stockholms stad äger stor del av marken i Stockholms kommun. När byggherrar vill bygga bostäder tecknar Stockholms stad och byggherrarna ett markanvisningsavtal. Vid tecknade av markanvisningsavtalet bestäms priset för marken men förvärvet genomförs först när fastigheten tillträds. Tillträdet sker vanligtvis efter två till tre år, då detaljplaneprocessen är klar, men ibland tar det längre tid. StoStockholm stad owns a large part of the land in Stockholm. When developers wants to build houses, Stockholm stad and the developer sign a land allocation agreement. When the land allocation agreement is signed, the price is determined for the land, but the purchase will take place when the developer gets access to the land. Access usually occurs after two to three years, when the detailed developm

The comprehensive use of plastic globally has raised many questions about how it will affect living organisms once it is disposed of and reaches the ecosystem. Disposing of plastic in high amounts without recycling could lead to several toxic effects for aquatic organisms and eventually humans. Accumulation of plastic for a long time leads to its aggregation and/or degradation into small sizes in

This study assess the climate consideration in building designs and aims to explore the extent of passive house performances in warm and humid climates. Previous studies have shown significant correlation between climate conscious building designs and meaningful improvements in indoor climate. The study uses a number of indices that are used to summarize indoor climatic parameters that describes h

In the early 21st century, deflationary trends applied pressure on margins in a range of different industries and subsequently cost reductions were required. Improving efficiency in the supply chain was identified as one of the key sources of potential cost savings. Subsequently, a trend towards slimmer supply chains with less stockkeeping emerged. However, due to the covid-19 pandemic supply chai

This work reports the research and findings concerning the processes of groundwater flow and distribution to lake Bolmen in the Småland region, Sweden. The watershed of Bolmen is of high interest since it provides water for drinking and energy purposes, representing a resource of notable importance for the society of southern Sweden. Among the main objectives there is the estimation of the water b

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Kardiovaskulär sjukdom (CVD) är ett i vårt samhälle växande problem där allt fler insjuknar i akuta hjärtinfarkter, stroke eller hjärtsvikt. Överlevnaden efter insjuknandet har förbättrats med åren med hjälp av nya mediciner och invasiva ingrepp såsom stentning av kranskärlen vid svår kärlkramp och direkt i det akuta skedet vid vissa tThis thesis examines the relationship between measures of renal function and cardiovascular disease (CVD) in patients with hypertension (the NORDIL study) and in the healthy population (Malmö Diet and Cancer Study, MDC) and whether antihypertensive treatment response and the risk of CVD is affected by genetic variation of a regulator of the renal amiloroide sensitive sodium channel (NORDIL).
