The Amit conjecture about word maps on finite nilpotent groups has been shown to hold for certain classes of groups. The generalised Amit conjecture says that the probability of an element occurring in the image of a word map on a finite nilpotent group G is either 0, or at least 1/|G|. Noting the work of Ashurst, we name the generalised Amit conjecture the Amit–Ashurst conjecture and show that th

Concerns over the earth’s ability to sustain itself over the long term as a consequence of human consumption of natural resources points towards sustainable development. Since a large proportion of human consumption is linked to buildings and construction, this means managing the construction process in more sustainable ways. Strategies that target greater material efficiency and which promote cir

Objectives: To conduct the first-ever nationwide, population-based cohort study investigating survival patterns of all patients with incident SSc in Sweden compared with matched individuals from the Swedish general population. Methods: We used the National Patient Register to identify patients with incident SSc diagnosed between 2004 and 2015 and the Total Population Register to identify comparato

The suitability of Hansen solubility parameters as descriptors for modelling analyte retention during reversed-phase chromatographic experiments was investigated. A novel theoretical model using Hansen solubility parameters as the basis for a complete mathematical derivation of the model was developed. The theoretical model also includes the cavitation volumes of the analytes, which were calculate

Prediction of analyte retention times requires prior knowledge of the column void volume, the measurement of which is still highly contested within the literature and therefore experimental based prediction is often used. In this study, we investigated deuterated acetonitrile as an isotopically labelled mobile phase component to observe its elution behaviour in a binary mixture with water at 25 di

Circularity in manufacturing is critical to reducing raw material usage and waste. Ecological embeddedness examines circular relationships intended to benefit both economic actors and the natural environment. By understanding circular relationships in the value chain, manufacturers can formulate strategies that are eco-effective. This work develops and validates an original circularity tool to mea

Industry 4.0 (I4.0) is an emerging concept describing the business setting application of a broad set of digitalisation technologies, connectivity, and automation. The most common critical infrastructure (CI) uses Industrial Control Systems (ICS) for operation and supervisory control. However, the Supervisory Control and Data Acquisition (SCADA) and Internet of things (IoT) systems are examples of

Safety, privacy and comfort are elements that need to be improved on Swedish shelters. Since several homeless individuals often share bedrooms, it is not uncommon for them to be exposed to violence, harassment and theft or a generally disturbing environment during their stay. These are all contributing factors to an increased difficulty in getting out of homelessness. Enfold is a flexible w

Mentors play a crucial role in preservice teachers' (PTs) professional development. Identity construction has not however been examined in the context of specific mentoring relationships, or as a process in motion. Drawing on the theory of the Dialogical Self, and its notion of dialogically constituted identities (I-positions), this case study explores PT identity construction and adaptive dynamic

This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. 14C-labeled ozone transformation products (OTPs) were generated by ozonation of 14C-labeled micropollutan

In the building industry, circular economy has gained much attention in recent years, yet thus far, little research has been conducted on the topic of intensified building use, despite the great potential this strategy offers in terms of emission reduction. One way of intensifying building use can be through the sharing of spaces among different users at different times. This thesis explores how m

The small body of research on writing and writing processes in the group of deaf and hard of hearing (DHH) children has shown that this group struggles more with writing than their hearing peers. This article aims to explore in what ways the DHH group differs from their peers regarding the written product and the writing processes. Participants are all in the age span 10–12 years old and include:

Purpose: Idea of circular economy defies the classical “make-use-dispose” approach of linear economic model. In the context of health-care industry, it relies heavily on the supply chain practices implemented by industry stakeholders. The purpose of this study is to explore such relationships, study their structure and put it across for attaining sustainability at large. Design/methodology/approac

From 1945 to 1946, Zygmunt Lakocinski (1905-1987) served as the head of the Polish Research Institute in Lund. The Institute conducted interviews with newly arrived concentration camp prisoners, thus documenting the traumatic wartime experiences of repatriates. With the evacuated former prisoners in mind, Lakocinski founded and served as the editor of the Polish-language weekly "Polak". The collec

One of the most critical issues faced by chemical industries is reducing the environmental impact caused due to pollution, which has resulted in global warming and health issues. Most chemical industries monitor and use Key Performance Indicators (KPIs) to control pollution, which is currently done by using various KPI's that are dependent on the product they are producing. Therefore, a study is c

Thermodynamic stability is a crucial fitness constraint in protein evolution and is a central factor in shaping the sequence landscapes of proteins. The correlation between stability and molecular fitness depends on the mechanism that relates the biophysical property with biological function. In the simplest case, stability and fitness are related by the amount of folded protein. However, when pro

Understanding the nature and origin of the precursor material to terrestrial planets is key to deciphering the mechanisms and timescales of planet formation1. Nucleosynthetic variability among rocky Solar System bodies can trace the composition of planetary building blocks2–5. Here we report the nucleosynthetic composition of silicon (μ30Si), the most abundant refractory planet-building element, i

This paper discussed construction industry’s ongoing battle with gender equality. Growing awareness of social sustainability responsibility has led to the mounting importance of human resources in the organisations. One perspective involves the focus on gender equality. Today women’s participation in the construction industry is still low except in times of acute labour shortages. This disproporti

Volunteer tourism is an alternative form of tourism that is constantly increasing. The increase can be considered related to trends about social participation, environmental awareness and moral demands. Volunteering in developing countries has previously been associated with altruism and social responsibility, but more recently volunteer organizations have used personal development as part of thei

Turkey, the country of failed and "successful" military coups, experienced the latest coup attempt on July 15, 2016, in which it is still unclear how, why, and by whom it originated. However, after this critical event, Turkish media and critical journalists were subjected to very strict censorship and repression. Hundreds of journalists were arrested for their views, and many had to flee
