The initial mass function (IMF) describes the stellar mass distribution for a population of stars at birth. This parameter represents a topic of long standing discussion within astronomy due to its apparent insensitive nature to environmental conditions. However, in the last decade, significant evidence suggesting the contrary has been presented. Due to the role of the IMF as an input variable for
Stålindustrin står för uppskattningsvis 7–9 % av de globala växthusgasutsläppen. Därför måste stålindustrin bidra till minskningen av växthusgasutsläppen. Under lång tid har stålindustrin fokuserat på mindre och frekventa inkrementella minskningar av CO2 utsläpp genom energieffektiviseringsåtgärder. Dessa åtgärder kommer inte att räcka för att nå målen som är överenskomna i Parisavtalet eftersom uThe steel industry is accountable for approximately 7–9 % of global GHG emissions. Therefore, the steel industry must contribute to the reductiuon of emissions of GHG. For a long time, the industry has focused on minor and frequent incremental reductions of CO2 emissions by implementing energy efficiency measures. However, these types of measures will not be sufficient to reach the goals agreed up
This paper seeks to provide an analytical framework for designing a more effective law enforcement for the crime of commercial sexual exploitation of children. The author has chosen to focus on a group of children particularly at risk in the society due to the lack of attention, namely accompanied children in the migration process. Out of a total of 1086 asylum seeking accompanied children arriv
With increased demand and high prices for minerals and metals in recent years, many resource rich developing countries see mining sector as vital to develop their economies. Colombia is one of these nations. Non-renewable natural resource wealth is seen as an opportunity to obtain economic benefits that can be transformed into increased wellbeing for citizens. However, mining often involves a high
Social services work with violent fathers The objective of this study was to review and analyze how social workers, employed by the Swedish social services, work with fathers that are domestically violent and to discuss their views and perceptions on this issue. Domestic violence is traditionally considered a private matter, and in the past has largely not been considered a child protection issue
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
Accelerated deforestation represents a major global environmental concern. Over the last decades Cambodia has experienced a drastic decrease in forest cover and measures to halt deforestation have not been as effective as planned. In order to support reforestation, as well as appropriate sustainable forest management practices, two aspects need to be taken into account: (a) the ecosystem functioni
Behovet av att skapa hållbara och flexibla byggnader har vuxit under de senaste åren, inte minst för att möta högt uppsatta klimatmål. Utrymmena mellan byggnaderna, med andra ord utemiljöer, har regelbundet prioriterats sekundärt och anpassats i stor utsträckning efter det bebyggda behovet. Utemiljöer i urban kontext innehåller ofta mer eller mindre kollektiva varor, som är icke-exkluderbara och iThe need for sustainable and flexible buildings has grown in recent years in order to meet climate goals. However, outdoor environments have often been overlooked and is often strongly controlled by the built environment. These spaces hold significant social and ecological benefits but pose challenges for real estate companies as they lack direct financial returns. Well-designed outdoor environme
“ We are both created and create.Why cannot our own creations also create?” Så lät uttalandet från den australienska domaren i det patenträttsliga fallet DABUS. AI är ett väldiskuterat samhällsområde där utvecklingen går så snabbt att det är svårt för lagstiftningen att hinna med. Uppfinnarbegreppet i patenträtten baserar sig på att det är en fysisk person som är uppfinnare. Det är lagstiftat i en“We are both created and create. Why cannot our creations also create?” That was the statement of the Australian judge in the DABUS patent case. AI is a rapidly developing and often discussed aspect of society where its accelerated development makes it difficult for legislation to advance at the same rate. The concept of inventor in patent law is based on the fact that it is a natural person who i
As I write this, there are numerous horrible wars and acts of terror taking place all over the world. However, it is my belief that the situation would be even worse without diplomats working as mediators, and for them to be able to fulfil their duties they need to be inviolable. Through the Vienna Convention on Diplomatic Relations of 1961, which is believed to reflect customary international law
Severe environmental degradation worldwide calls for imperative action from human society. Small- and Medium-sized Enterprises (SMEs), which constitute an important component in almost every economic entity in the world, are subject to growing concern, as their environmental performance is essential to regional and global environmental protection and sustainable industrial development. Due to the
The purpose of this work has been to perform numerical calculations on the cubical mixing tank the QB mixer, to be able to verify its strength and try to improve it. The QB mixer is produced by the company QB FoodTech AB. Firstly a CAD model was made from drawings of the mixer. Then the structure was analysed in aspects of pressure load, thermal loads and gravitational load. A modal analysis to ge
Kevin Roberts has extended the comprehension of strong consumer brands to a higher level where loyalty beyond reason is established. He calls this new status Lovemarks. As the concept of Lovemark has only been applied in B2C markets, this thesis is directed to find out the applicability of Lovemarks in B2B context. In order to fulfill the research purpose, three main questions are answered based o

High school educators and administrators are increasingly concerned about educating and engaging their students in sustainability issues. Consequently, curricula in many schools are being redesigned in order to focus upon these issues and their consequences. This thesis describes a project, ‘Scholen voor Duurzaamheid’ (Schools for Sustainability, SvD), that is being used as a springboard in Dutch
Det huvudsakliga syftet med detta arbete var att simulera tredimensionella flödesmönster i tankar för lagring av vatten. De praktiska avsikter med simuleringarna var att identifiera vattenkvalitetsproblem relaterade till bristande vattenutbyte. De vattenmagasin som reservoarer vid Norra Ugglarp i Skåne utgör undersöktes i en särskild fallstudie. I denna avhandling har den öppna CFD källkoden OpenFThe main purpose of this thesis was to simulate the three-dimensional flow patterns in tanks for water storage. The practical intentions of the simulations were to identify water-quality problems related to insufficient water exchange. The water storage reservoirs at Norra Ugglarp in South Sweden were investigated as a special case study. In this thesis, the open source CFD software OpenFoam was c
Electrical resistivity tomography has potential as a complementary long-term monitoring method in embankment dams; however, the 3D character of the geometry including the shape of the embankment, its internal zoned construction and the reservoir water make interpretation challenging. To tackle this problem, a qualified inversion model considering the 3D environment is necessary. In this paper, pri
How global gridded crop models (GGCMs) differ in their simulation of potential yield and reasons for those differences have never been assessed. The GGCM Intercomparison (GGCMI) offers a good framework for this assessment. Here, we built an emulator (called SMM for simple mechanistic model) of GGCMs based on generic and simplified formalism. The SMM equations describe crop phenology by a sum of gr
Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others. The range of exper
The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. For a carton this is defined by the repulpability, i.e., the ab
