The majority of terrestrial plants associate with arbuscular mycorrhizal (AM) fungi, which typically facilitate the uptake of limiting mineral nutrients by plants in exchange for plant carbon. However, hundreds of non-photosynthetic plant species—mycoheterotrophs—depend entirely on AM fungi for carbon as well as mineral nutrition. Mycoheterotrophs can provide insight into the operation and regulat
In this paper, we introduce a novel framework for semi-parametric estimation of an unknown number of signals, each parametrized by a group of components. Via a reformulation of the covariance fitting criteria, we formulate a convex optimization problem over a grid of candidate representations, promoting solutions with only a few active groups. Utilizing the covariance fitting allows for a hyperpar
This paper presents an innovative study of the port system of Rome in Imperial times through the application of an integrated approach to both archaeological analysis and material evidence. Specifically, it seeks to provide a more complete contextualization and understanding of the port system of Rome by focusing on the exploration of the physical geography of the river Tiber and its transformatio
The integration of daylight and electric lighting, considering user satisfaction and energy savings potentially can contribute significantly to reduce energy demand for lighting, that represents 18% of global energy demands. This paper presents the work and first results of IEA SHC Task 61/EBC Annex 77 “Integrated Solutions for Daylighting and Electric Lighting: From component to user centered
The thesis discusses community development in fast track resettlement areas of Zimbabwe. The land reform programme designated as the Third Revolution (Chimurenga) or fast track land reform was launched in 2000. This programme saw 12 million hectares of farming land being taken over by the state for resettlement. This research conducted in Mazowe district of Zimbabwe, provides an insight on the typ
Business challenges today are becoming more numerous, and more urgent. Many companies are expanding beyond their traditional product and market boundaries, while others are forming new alliances or outsourcing supporting functions to other producers. The concept of product-service system (PSS), analysed in this study, has the potential to improve companies’ competitiveness and provide new business
Packaging is becoming increasingly important from a marketing as well as logistics perspective, particularly for actors in consumer product supply chains. However, the role of packaging in creating or contributing to the competitive advantage of a company or a whole supply chain is still unexplored to a large extent. This is even the case in businesses where research has shown the benefits of cons
1 INTRODUCTION In a global and highly competitive economy, companies have now adopted an increasingly integrated ap-proach to product development. However, packaging logistics has been left out from this integration trend. The reasons are multiple: first packaging is not considered to be an integral part of the product, so it is not part of the product “culture” of the company. In most companies,
The implementation of circular initiatives requires certain capabilities and knowledge that traditional business models often lack, requiring new perspectives and external collaborations. This paper explores the competency needs and partnership dynamics of established companies collaborating for business model innovation for circularity through a case study of a gap exploiter business model, a com
Adopting circular business models (CBM) represents a key lever for industry to address urgent global challenges. Prior research recognizes the need for systems thinking and collaboration, but existing CBM tools and methods often implicitly assume that the focal firm has direct access to end customers, usage data and end-of-life phases. However, upstream suppliers who lack this access often produce
Augmented reality (AR) games are a rich environment for researching and testing computational systems that provide subtle user guidance and training. In particular computer systems that aim to augment a user's situation awareness benefit from the range of sensors and computing power available in AR headsets. The main focus of this work-in-progress paper is the introduction of the concept of the in
We have developed a microfluidic chip for isolation of circulating tumor cells (CTCs) in blood based on microchannel acoustophoresis. Ultrasound radiation forces are used to separate cancer cells from blood cells in a continuous flow format. Separation was dramatically improved after incorporation of a 2-dimensional acoustic pre-alignment of the cells before entering the acoustophoresis separation
The research project Innovative Solutions for Cross Laminated Timber Structures (InnoCrossLam) wasrecently finished. The project aimed at increasing the competitiveness of CLT as a versatile engineered product, byincreasing its predictability in demanding design situations not covered by the guidelines of today, or standards and codesforeseeable in the near future (e.g., second generation of Europ
Armed conflicts are acknowledged for their effects on the environment, includingecosystem degradation and biodiversity loss, but also ecological restoration. Bothprocesses impact post-conflict opportunities for peace and development. The armed conflict in Northern Uganda (1986–2008) profoundly affected local communities and their natural environment. While some areas suffered environmental degrada
The strategies, decisions and beliefs of those who occupy prominent positions of economic power have influence on very large corporations and the markets they dominate, on vast amounts of economic resources, and on the rules of the game. However, the sociology of elites faces a dual challenge: divergent conceptualisations of what can be considered as a position of economic power and internationall
Reliable electrical power supply is a requirement for the modern society, therefore it is important to analyse the vulnerability of the electric power system. Network analysis has previously been used to analyse the vulnerability of electric transmission systems, however recent events in Sweden have shown that perturbations in distribution systems also can cause severe societal consequences. Thus,
There are about eight thousand and five hundred of level crossings in Sweden according to Swedish Transport Administration (STA). Approximately four thousand and six hundreds of railroad crossings are arranged without any type of protection. Most of the accidents occurs when there are none protection or the amount of traffic is very low. Types of protections that are usually used in most of the le
Skuldfinansiering inom koncerner har under senare år blivit ett mer förekommande fenomen. Vid finansiering med lån är utgångspunkten att det ska utgå marknadsmässig ränta. För det långivande bolaget uppstår en ränteintäkt, vilken är skattepliktig. För det låntagande bolaget som betalar ränta till det långivande bolaget uppstår istället en ränteutgift. Ränteutgiften är en avdragsgill kostnad för deDebt financing within groups has become a more common phenomenon in recent years. When financing with loans, the starting point is that market interest must be paid. For the lending company, interest income arises, which is taxable. For the borrowing company that pays interest to the lending company, an interest expense arises instead. The interest expense is a deductible cost for the borrowing co
