Electrothermal energy conversion provides attractive solutions for global energy management, such as energy harvesting from waste heat using pyroelectric energy conversion (PEC) and efficient cooling of portable electronics or data servers using the electrocaloric effect. Relaxor ferroelectrics are attractive for electrothermal energy conversion because of their large pyroelectric coefficients ove

Human agency has become a core topic in economic geography complementing traditional, structural approaches to explain regional development. This paper contributes firstly with a discussion of the theoretical and conceptual relationships between the agency of individuals, organizations, and systems. Secondly, it proposes a novel analytical framework for studying how human agency, combined with ext

Background: Primary spinal tumors are rare. Symptoms depend on the size and location of the tumor.Case description: A patient presented with a rare clinical finding, Brown-Séquard syndrome. The symptoms were caused by an extramedullary tumor compressing on the thoracic spinal cord. Pathologic examination showed cavernous hemangioma with growth both intradurally and extradurally.Conclusions: This i

There is over 15,600 km of track in the Swedish railroad network. This network is vital for the transportation of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety. A tool for monitoring and measuring ground deformation over a large area remotely with high frequency and accuracy was developed in recent decades. Thi

Transurethral resection of the prostate (TURP) remains the gold standard for the surgical treatment of benign prostatic hyperplasia. Complications during the procedure are rare. An extremely rare complication is a rupture of the urinary bladder. This article reports a case where an explosion occurred during TURP, resulting in a large intraperitoneal rupture of the urinary bladder. The patient unde

Superior canal dehiscence is a rare syndrome. The symptoms consist of hearing loss, dizziness and autophonia. The patient can be cured with surgery. A 28 year old woman went to several doctors for several months due to diminished hearing, dizziness and autophonia. The symptoms got worse. A work-up led to the diagnosis of superior canal dehiscence in the left ear. She underwent surgery and her symp

The Nairobi Summit on ICPD25 provided an opportunity to complete the unfinished business of the International Conference on Population and Development Programme of Action and also a chance to commit to a forward-looking sexual and reproductive health and rights agenda to meet the Sustainable Development Goals and targets by 2030.This background document for the Nairobi Summit on ICPD25 was conceiv

Introduction: Gallbladder carcinoma is about 0.5% of all cancer. The outcome of patients with gallbladder carcinoma is overall bad and the only potentially curative treatment is surgery. The aim of this study was to determine the disease's prevalence in Iceland and outcome of the patients diagnosed in the study period.Patients and methods: This was a retrospective study of all diagnosed patients w

This paper shows the advantage of using both 3d models and surgical navigation system when preparing and planning complex brain surgery. The novel clinical process introduced here combine CT and MRI images in special computer program where the regions of interest are isolated e.g. the skull base, tumor and other soft tissue. A 3D model is calculated from the segmented masks and printed using Rapid

AbstractBackgroundMotion tracking during live surgeries may be used to assess surgeons’ intra-operative performance, provide feedback, and predict outcome. Current assessment protocols rely on human observations, controlled laboratory settings, or tracking technologies not suitable for live operating theatres. In this study, a novel method for motion tracking of live open-heart surgery was develop

Retroperitoneal tumours rarely cause significant symptoms, therefore they are frequently diagnosed incidentally. Ganglioneuroma is a rare tumour that most often present in the posterior mediastinum or the retroperitoneal cavity. In the present case, a solitary ganglioneuroma is diagnosed in the retroperitoneum in an young healthy male, a rather typical presentation of this benign tumour.

This article examines the outcome of the International Law Commission’s (ILC) Study on the Protection of the Environment in relation to Armed Conflict as adopted on first reading. The twenty-eight draft principles, adopted by the ILC in July 2019, aim to enhance environmental protection before, during, and after armed conflict. This article evaluates the strengths and weaknesses of the draft princ

The environment suffers enormously during armed conflicts and, despite the increasing awareness of the pressing need to protect the planet, devastating environmental damage can occur legally at times of war. This book suggests that – apart from the protection offered under law of armed conflict – environmental treaties or multilateral agreements (MEAs) can complement and strengthen environmental p

Vi redogör för ett patientfall med covid-19-associerad myokardit.Patienten hade förhöjda hjärtskademarkörer, men inte avsevärt stegrade inflammationsmarkörer såsom D-dimer och interleukin-6. Tidigare fallrapporter indikerar att en myokarditbild kan uppträda vid covid-19, både genom förekomst av sars-cov-2 i myokardiet och immunologisk aktivering. I detta fall var orsaken sannolikt infektion i myok

This article aims at questioning the uses of feminist epistemologies and methodologies in the context of a fieldwork project conducted in Colombia on the return to civilian life of female combatants. While the topic « female combatants »tends to be the object of an academic over-investment, contributing to its depoliticization, the Authors discuss the various approaches, tools and methods produced
