Soil degradation is one of the most serious environmental problems in the highlands of Ethiopia. The prevalence of traditional agricultural land use and the absence of appropriate resource management often result in the degradation of natural soil fertility. This has important implications for soil productivity, household food security, and poverty. Given the extreme vulnerability of farmers in th
This paper provides one of the first studies on the role of social media in articulating individuals’ experiences and memories and (re-)shaping collective memory in contemporary China. It investigates how social media enable and facilitate the participation of ordinary citizens in distributing and accumulating alternative narratives and memories of the past against the authoritarian version by tak
Recent technological advancements now allow us to obtain geographical position data for a wide range of animal movements. Here we used light-level geolocators to study the annual migration cycle in great reed warblers (Acrocephalus arundinaceus), a passerine bird breeding in Eurasia and wintering in sub-Saharan Africa. We were specifically interested in seasonal strategies in routes and schedules
Context. To use the data in the future Gaia catalogue it is important to have accurate estimates of the statistical uncertainties and correlations of the errors in the astrometric data given in the catalogue. Aims. In a previous paper we derived a mathematical model for computing the covariances of the astrometric data based on series expansions and a simplified attitude description. The aim of th
This quantitative study aimed to provide an in-depth understanding of how distance education has affected social worker students' study motivation and social contacts.This study collected its data by sending web based surveys to the social work students in Lunds University who, in may 2022, currently were on term 6 and 7 (n=311) with the purpose to measure how they felt about the education bec
Initiation of construction of apartments has increased by 26% from 2014 to 2015 in Sweden. This has meant more building permits to treat. Several tasks done by a building inspector has been identified through active observation of the building permit department in Helsingborg. Some of the tasks are review of cases, technical consultation, and visits at building places, final consultation, supervis
Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. The measurement of gas channel temperature is also a source of error due to th
Räddningstjänstens personal har ett arbete med stora krav på fysisk och psykisk stryka. I mindre kommuner är flertalet anställda på deltid och har andra arbeten på heltid att sköta. De har jour och beredskap och de förväntas träna och underhålla sin kapacitet. I denna undersökning jämförs 145 personers hälsovärden, (BMI, blodtryck samt blodsocker) från två undersökningstillfällen med ett års inter
In probability theory, the assumption of independence between consecutive events is strong. However, when analyzing empirical data, this assumption is often weak or violated. This thesis investigates whether extreme negative daily returns in stock indices occur independently over time. To address this question, self-exciting Hawkes models are applied to extreme negative returns in two stock indice
Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. Biomethanol and substitute natural gas, are two fossil free energy carrier, they can both be produced through g
Introduction: The main route of excretion of activity for most administered radiopharmaceuticals is via the urinary bladder and it is important to estimate the absorbed dose to the mucosal surface of the bladder wall, especially when radiopharmaceuticals are given for therapeutic purposes. The purpose of this thesis was to investigate how the absorbed dose varies with changes in the parameters, wh
Barn som är under 15 år kan inte straffas i svensk rätt enligt 1 kap. 6 § brottsbalken (BrB) och därmed kan de inte heller bli föremål för rättsväsendets åtgärder p.g.a. brott. När samhällsåtgärder därmed måste tas, ligger ansvaret på socialtjänsten. Begår ett barn ett brott kan det ändå utredas av polis och åklagare genom stöd av lagen om unga lagöverträdare (LUL), en s.k. 31 § LUL-utredning. SChildren under the age of 15 can commit crimes but they cannot be punished under Swedish law in accordance with Chapter 1, Section 6 of the Criminal Code and therefore they cannot be subject to a preliminary criminal investigation by a Prosecutor or the Police. Instead, when children have committed a crime other societal measures can be taken. The responsibility for the care for these children lie
Previous research has established that when engaged in episodic memory retrieval, people frequently look at locations associated with the sought-after memory trace, even if those locations no longer contain any information. While it has been further demonstrated that gaze positions showing compatibility between encoding and retrieval increase the likelihood of successful remembering (Johansson &amPrevious research has established that when engaged in episodic memory retrieval, people frequently look at locations associated with the sought-after memory trace, even if those locations no longer contain any information.

Small animals that winter at northern latitudes need to maximize energy intake and minimize energy loss. Many passerine birds use night-time hypothermia to conserve energy. A potential cost of night-time hypothermia with much theoretical (but little empirical) support is increased risk of night-time predation, due to reduced vigilance and lower escape speed in hypothermic birds. This idea has neve
Protein synthesis, measured as [14C]-leucine incorporation into proteins, was studied in the normothermic rat brain following 15 min of transient cerebral ischaemia and 1 h, 24 h and 48 h of recirculation, and in the hypothermic (33°C) brain following 1 h and 48 h of recirculation. Ischaemia was induced by bilateral common carotid occlusion combined with hypotension. Following normothermic ischaem
Background: The COVID-19 pandemic has rapidly led to some of the most revolutionary changes in private and professional life around the world. While the extent and duration of these changes are not certain, they have already had a great impact on travel patterns. This is also the case in Sweden, despite its relatively liberal approach to restrictions, which relies on voluntary measures such as soc
Brazil's Atlantic Forest biome is one of the world's biodiversity hotspots, whose heterogeneous ecosystems are threatened by habitat loss and climate change. Palaeoecological research can provide essential context for the impacts of anthropogenic climate change in the 21st Century and beyond, but existing studies have notable limitations in the insights they can provide: vegetation proxy data are
Nemo-like kinase (NLK) is a member of the mitogen-activated protein kinase family of kinases and shares a highly conserved kinase domain with other mitogen-activated protein kinase family members. The activation of NLK contributes to the pathogenesis of Diamond–Blackfan anemia (DBA), reducing c-myb expression and mechanistic target of rapamycin activity, and is therefore a potential therapeutic ta
