Fjärrvärmen är en mogen uppvärmningsteknik som under lång tid har byggts ut i Sverige. Stora delar av fjärrvärmebolagens kapital består av ledningarna som är nedgrävda i marken. Att ha kunskapen om statusen på sina fjärrvärmeledningar är viktigt för att kunna undvika kostsamma skador och bedöma förnyelsebehov. För de äldre delarna av fjärrvärmenätet, där ledningarna är förlagda i kulvertar har det

Syfte: Det generella syftet med denna studie var att utifrån en webbenkät undersöka rösthälsan hos friska äldre individer i åldrarna 65-80 år. Det specifika syftet var att undersöka hur män och kvinnor skattade sin nuvarande rösthälsa och jämföra med hur de uppfattade att rösten fungerat under arbetslivet.

This master’s thesis explores how capacity planning in outsourced manufacturing can be improved through sales and operations planning (S&OP). The master’s thesis was done in collaboration with Axis Communications AB, where the capacity planning and S&OP processes were analyzed. Managing manufacturing capacity in high technology industries is one of the most important aspects to consider fo

Molnens roll i klimatsystemet har studerats och deras påverkan på solens inverkan på jordens energibalans. Jordens albedo påverkar energibalansen genom att den påverkar hur mycket av solens instrålning som reflekteras eller absorberas. Moln påverkar jordens albedo och spelar därför en viktig roll i denna balans. Molnbildning sker till nära 100% i troposfären och där finns allt det vi kallar väder.The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. Cloud formation occurs almost 100% in the tropospher

Lithium-ion batteries (LiB) are witnessing an increasing demand for electric vehicles. It provides a sustainable energy storage solution that is more efficient and ecofriendly than the fossil fuels. However, LiB are prone to ageing, which changes the dynamics of the electrochemical reactions over time and usage, and consequently affects its life and performance.. Ageing can manifest through multip

Gender role conflict (GRC) was originally developed to evaluate men’s health in relation to perceived “masculinity”. In previous studies, GRC has been associated with poor mental health and low help-seeking behavior in men. In this study, we expanded on previous research and were able to demonstrate that also women and genderqueer individuals can display GRC. An aim was also to investigate any po

Catastrophe (CAT) bonds bring the needs of (re)insurance companies and investors together: They insure against natural disasters by transferring risk to the capital market while at the same time promising high returns and a certain detachment from financial markets. Being an alternative investment class that has been on the rise only in recent years, academic research on CAT bonds is comparatively

With the rise in urbanization and cities fulfilling sustainability challenges, companies across the globe are moving towards circularity. One approach adopted towards circularity is of reverse logistics where companies take back EOL/EOU products. In the furniture industry, this approach towards circularity is coupled with consumers being asked to transport the EOL/EOU furniture to second-hand/ret

Om en part har tillräckligt starka misstankar om att motparten inte kommer att fullfölja sina avtalsförpliktelser och begå ett avtalsbrott vill den drabbade parten naturligtvis skydda sig från att drabbas av brottet. Den drabbade parten kan skydda sig mot ett s.k. befarat avtalsbrott genom att utöva stoppningsrätten eller hävningsrätten. Stoppningsrätten regleras i 61 § KöpL och innebär att den drIf a party suspects the other party will not fulfill a substantial part of his obligations according to the contract this would mean that they are breaching the terms of their contract. This means that the affected party can protect itself against a breach of contract, “anticipatory breach”, under contractual law by exercising the rights of suspension or cancellation (stoppningsrätten or hävningsr

Although most individuals consider gambling to be an innocent and fun activity, when it develops into problem gambling (PG), it can have detrimental outcomes to one’s life, such as over-indebtedness. This study explores the role of maladaptive personality traits and gender in both PG and over-indebtedness, in an online sample of 1479 adult gamblers in Sweden. Participants were administered the Pro

Respiratory tract infections (RTIs) pose severe threats to global health. The microbial profile of the respiratory tract largely impacts their ecological niche. Epidemiological studies indicate that nasopharyngeal colonization of commensals like Corynebacterium spp is associated with reduced rates of RTIs, but the underlying mechanisms are undefined. Besides, most pathogens like Streptococcus pneu

The goal of this thesis was to, from several randomly selected patients with diagnosed malignant and benign tumors, record optimal lambdas and respective Renyi entropies for each lambda, run a basic statistical analysis of the results and see if there is any significant difference between lambdas/Renyi entropies of malignant and benign lesions.\\ The results showed no significant difference.\\ The

Privata sjukvårdsförsäkringar har ökat de senaste åren i Sverige. Detta trots att Sverige har en offentlig vård som ska ge en vård på lika villkor för hela befolkningen. Vilka faktorer kan påverkar en sådan ökningen av privata sjukvårdsförsäkringar och eventuella underliggande anledningen finns det till att anskaffa en sådan försäkring. Studien syftar till att diskutera motiven till detta köp med

Differentiated instruction is a widely known approach used in different educational settings, especially in diverse classrooms. Teachers are expected to be able to meet the need of all learners and differentiate instructional parameters such as content, process and product accordingly. While previous research has shown that a successful implementation of the concept is beneficial for the students,

Buildings are a are a major consumer of energy in urban areas. The use of solar energy in buildings can help reduce CO2 emitting energy consumption in these urban areas. One way to use solar energy is through passive solar energy systems. Passive solar energy systems allow a building to use daylight as an energy source. The use of daylight as passive solar energy in Sweden could reduce the energy
