Popular Abstract in English Among the forms of life found in extreme environments (e.g. high temperatures ‘thermo’ and oxygen deficient ‘anaerobe’), the thermoanaerobic bacteria emerge as a highly evolved and interesting subject of study. Bacteria living as microbial mats in decaying plant material possess a great potential not only to degrade complex biomass but also to produce special chemicals.A novel ethanol-producing thermoanaerobe Caloramator boliviensis 45BT (=DSM 22065T, =CCUG 57396T) was isolated from a hot spring of the Bolivian highlands. C. boliviensis possesses the ability to utilize a wide range of substrates and can efficiently convert hexoses and pentoses into ethanol with concomitant production of acetate, carbon dioxide and hydrogen as by-products of fermentation. However

This investigation concerns written output produced by Swedish learners of English as a second language (L2) and French as a third language (L3). The analysed texts were rated according to the Common European Framework of Reference for Languages (CEFR), which is a widespread and language-independent document commonly used to assess communicative competence based on six main proficiency levels (A1,

The aim of this chapter is to outline a theoretical framework for the comparative study of emotions in Western legal systems of different countries. Our focus is on the legal actors, and our primary interest is how internal legal culture – conceptualized as ‘the emotive-cognitive judicial frame’ – is embedded in a broader context of a socio-culturally specific emotional regime. The emotive-cogniti

Thin-film thermocouples (TFTCs) are critical for real-time temperature monitoring in advanced manufacturing processes where conventional sensors fail due to spatial constraints or complex geometries. This study develops K-type TFTCs on stainless steel 316 L substrates with optimized SiO₂/SiO insulation layers for industrial deployment. In particular, two types of stainless steel substrates were in

Breast cancer is the most common type of cancer in women worldwide. Triple-negative breast cancer (TNBC) is a subtype of breast cancer that lacks the expression of the oestrogen receptor, progesterone receptor, and amplification of HER2. This subtype is the most aggressive subtype and a heterogeneous subgroup of breast cancer, making up around 10-15% of the cases, often affecting younger patients

Microplastics are being found in large amounts in the environment. In samples from Sweden’s west coast 4000-100000 particles of microplastic/kilogram of dry samplewas found. One of the larger pathways into theenvironment for microplastic is believed to be stormwater. Yet there is no standard method to analyse this pollution. This study was made to get an understanding of the amount of microplastic

The external ventricular drain (EVD) is an important instrument in the management of neuro-intensive care patients through its ability to meassure intracranial pressure and to treat increased intracranial pressure by drainage of cerebrospinal fluid (CSF). However, EVDs are associated with the risk of external ventricular drain related infection (EVDRI). EVDRI diagnosis is challenging as symtoms an

BackgroundCurrent guidelines from Scandinavian Neuro Committee mandate a 24-hour observation for head trauma patients on anticoagulants, even with normal initial head CT scans, as a means not to miss delayed intracranial hemorrhages. This study aimed to assess the prevalence, and time to diagnosis, of clinically relevant delayed intracranial hemorrhage in head trauma patients treated with oral ant

Notch wear often determines tool life when machining stainless steel. Chemical Vapour Deposited (CVD) Al2O3/Ti(C,N) coated cemented carbide tools are the first recommendation for turning of stainless steel. The CVD coating plays a vital role in reducing and delaying tool wear progress. Hence, it is essential to understand the interaction between the initiation of notch wear and the coating degrada

In stainless steel turning, cutting tool life is often limited by excessive localised damage at the depth of cut line, known as notch wear. Previous research revealed that notch wear in CVD (chemical vapour deposition) Al2O3/Ti(C,N) coated WC-Co tools begins as a coating brittle fracture already after 0.3 m of cutting. This paper investigates the impact of cutting tools and workpiece materials on

Tool wear intensity is one of the major performance and economic indicators of metal cutting processes. Understanding and control of tool wear and its governing mechanisms enables effective and sustainable manufacturing. Known wear mechanisms include abrasive, adhesive, chemical and diffusional, where their individual or combined action leads to an overall tool degradation. In this study, we prese

Hard-to-heal wounds are a growing human and financial concern, constituting approximately 1–3% of the healthcare budget. Wound care is not a medical specialty and is often not prioritized within healthcare. A large portion of the cost and suffering caused by wounds has the potential to be mediated through improved knowledge and effectivised workflows. One potential way to achieve this is through t

Recent research has indicated that machining of titanium alloys with uncoated cemented tungsten carbide tools fulfil the criteria for Kirkendall porosity. If this occurs during machining, it could contribute to the type and rate of tool wear, compromising the tools structural integrity close to the edge line within the contact zone. In this study, voids were observed at the tool-workpiece contact

Carbon Fibre-Reinforced Polymers (CFRP) are a fast growing market of high performance materials and components. Thermally induced damage during machining processes such as drilling or routing are among the limiting factors for product quality, yet accurate temperature measurement remains challenging. This study develops a methodology which combines machinable thermocouples and IR thermometry techn
