Järn är en metall som finns i överflöd på vår jord. Den är säker, är ett av de mest använda grundämnena genom den mänskliga historien och finns naturligt inom varje människa. När den kombineras med andra atomer kallade ligander för att bilda ett så kallat komplex, kan den ifall den får lov att absorbera ljus, uppvisa fotokatalytiska egenskaper. Detta innebär att den omvandlar det inkommande ljusetIron is one of the most versatile transition metals on the planet, and it is the fourth most plentiful element in the crust on earth. It is among numerous things, endogenously, vital to the human organism, and exogenously, safe to handle. When combined with ligands to form a complex, it exhibits qualities that of catalysing light into viable energy, which can be harnessed to sustain different elec

In the rapidly evolving telecommunications industry, customer retention is crucial for maintaining profitability. This report investigates the performance of various machine learning models in predicting customer churn rates, which are integral to calculating Customer Lifetime Value (CLV). The focus is on a comparative analysis of several models including logistic regression, ridge regression, las

This essay aims at contributing to the existing knowledge about Result Based Financing (RBF) programs to poor and mid income countries. Results Based Financing (RBF) program may be referred to as an umbrella term referring to any program or intervention that provides rewards to individuals or institution after agreed-upon results are achieved and verified (URT 2015). The RBF program was introduced

Uganda faces various challenges related to compliance, including tax evasion, regulatory non- compliance, and violations of legal standards, laws, policies and regulations among others. These issues undermine the government's ability to collect revenue, provide public services, and maintain law and order. Enhancing compliance is not only a matter of enforcing penalties but also involves creati

This chapter addresses the background of the study, statement of the problem, objectives or aims of the study research questions, significance of the study and scope of the study. The Uganda Maritime Regulatory Framework is a Service that helps to overcome borders and barriers that affect interaction and form a greater part of probably the most characteristic dimension of cross - border networks t

This section gives an overview of Lake Victoria, that is currently underutilized for cargo transportation by the 3 East African states of Uganda, Kenya and Tanzania, despite the great potential of this shared water body for multimodal transport and trade opportunities. In order to sustainably develop infrastructure on Lake Victoria, the three member states must adopt sustainable business models t

Semi-natural grasslands in Scandinavia have been created by humans since many millennia ago, but the agricultural intensification in the last few centuries caused them to decline heavily. Accordingly, the biodiversity associated to these open, nutrient-poor habitats declined as well and many remnant populations are slowly declining and threatened to go extinct. In this study, I focused on declin

Insects are the most diverse group of animals, and among the largest contributors to species richness, accounting for around 66% of known species on Earth. Insects are extremely important pollinators, and to understand the timing of pollination, age distribution within time could give important information. Pollinator phenologies advance more rapidly than plant phenologies that can lead to pollina

The Aim of this thesis was to answer the research question “what are the actors that create an social atmosphere and how do these actors collectively form and maintain the affective atmosphere at maid cafes”. This was done by explaining the modern life in japan with muen shakai, and the collapse of the traditional family structure. This was then put in connection to an explanation of previous rese

The endemic Philippine crocodile (Crocodylus mindorensis) is considered the most threatened crocodile species globally and is listed as critically endangered on the IUCN Red List. The species was considered extinct on Luzon Island until the discovery of a remnant population in 1999. This led to the first in-situ conservation measures and later community-based conservation. Public perception has pr

Introductions of managed honeybees has been shown to negatively affect wild bees due to increased competition for resources, which threatens to dismantle key ecosystem functions such as pollination. This thesis aims to assess the influence of hive proximity on wild bee richness and abundance, as well as niche overlap, and if these processes are mediated by functional traits and environmental facto

The Gulf of Thailand is a region with a relatively high coral cover, despite having many stressors on the reef such as the bi-annual monsoon and high temperatures. Assessing coral reefs in this area can provide insight into how these reefs maintain their coral cover and seem to replenish the reef, increasing resilience to future extreme events. This study assesses the conditions on the reef flat a

The understanding of interspecific interactions is key to understanding the complexity, diversity, and evolution of land plants. Bryophytes, including mosses, are a diverse group of non-vascular plants that are especially important to study, as they are key parts of ecosystems, are chemically diverse, and have a gametophyte dominant life history. Genetic studies revolving around interspecific inte

Sammanfattning Som en konsekvens av den pågående debatten om vattenkraftverkens samhällsnytta och klimatpåverkan finns ett allt större krav på att riva eller miljöanpassa kraftverksdammar i Sverige. I Rönne å i Klippans kommun har tre vattenkraftverk lagt ner sin elproduktion i samband med att dammarna ska rivas nästa år. I det här examensarbete tar jag ställning till en ny potentiell framtid förAbstract As a consequence of the ongoing debate about the human benefits and detrimental climate impact of hydropower plants, there is an increasing call to either demolish the dams or environmentally adapt them across Sweden. In Rönne å, three hydropower plants have shut down their electric production as their dams are set to be demolished next year. In my thesis, I take a position on a new pote

In this thesis we performed a pooled cohort study to investigate the role of radiomics in head and neck cancer prognosis. The aim was to investigate prognostic value for overall survival and cancer recurrence of radiomics combined with previously studied demographic and clinical risk factors. Radiomics features were extracted from the gross tumor volume on a computed tomography captured prior to r

In the past decade, studies have examined how the Russian-speaking minority reacted to changes in citizenship, language, and memory politics. However, one aspect that has not been studied is the response to educational policy changes during an ongoing conflict. This study investigates the resistance strategies of Russian-speaking mesolevel actors against minority education policy changes before an

Nanowires are promising structures for improving light absorption due to their enhanced optical properties compared to bulk materials. Silicon is a suitable semiconducting material for driving water splitting in a photoelectrochemical (PEC) cell, and is particularly attractive due to its small bandgap as well as its relative abundance and low cost. PEC cells can be enhanced by including silicon na

Photoperiod, the relative duration of daylight in a 24-hour diel-cycle, is an environmental cue that influences physiological processes in birds, regulating life-history events such as reproduction and migration. Here we study whether variations in photoperiod affect migratory behaviors, including activity, orientation, and body mass, across bird species during 2023 spring and autumn migration. Ou

Understanding the dynamic of a population via either abundance or density is crucial for wildlife conservation. The brown bear (Ursus arctos) is a commonly distributed, yet elusive species, playing a major role in the ecosystem. Usually monitored with genetic sampling, hunted bags, or telemetry data, the use of camera traps for bear monitoring is still to this day a rarely used, yet promising meth

Restaurering av betesmarker i Ecuador: Växtkrav för Salvia corrugata och Macleania rupestris Övergivna betesmarker och fält i det syd-andinska landskapet i Ecuador har ofta under lång tid utsätts för urlakning av näringsämnen och jordpackning, något som begränsar den naturliga etableringen av träd och buskar. Då mängden övergiven mark ökar blir landskapet alltmer fragmenterat och inhemska växt arThe Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
