[1] Vigorous debate still surrounds the cloud electrification process and unexplained regional variations in lightning activity. Here, we show that climatological maxima in lightning activity are associated with small effective diameter D-e of ice crystals near cumulonimbus cloud tops. This relationship, unlike lightning's more well-known relationship with cloud top height, is consistent over land

The accurate estimation of soil carbon (C) pool and fluxes is a prerequisite to better understand the terrestrial C feedback to climate change. However, recent studies showed considerable uncertainties in soil C estimates. To provide a reliable C estimate in the grasslands of the Qinghai-Tibet Plateau (QTP), we calibrated key parameters in a process-based ecosystem model (the CENTURY model) throug
Aluminum matrix fly ash (AMFA) cenosphere composites were fabricated using the stir casting technique. The used type of fly ash cenosphere, which accounted for over 60% in all fly ash particles, was in narrow and small size (2-30 μm). During synthesis, effects of several key technological parameters on microstructure and properties were investigated using orthogonal experimental design. The optima
This brief presents an on-chip memory subsystem for massive multiple-input-multiple-output (MIMO) baseband processing at the base station. In massive MIMO systems, the required memory bandwidth and capacity are orders of magnitude higher than those used in conventional wireless systems, due to the large number of serving antennas. These are further combined with design targets on low access latenc
Populärvetenskaplig sammanfattning1,7 miljoner nya fall av bröstcancer diagnosticeras årligen i världen. Bröstcancer är kvinnans vanligaste tumörsjukdom och i västvärlden samt Sverige kommer var åttonde till var nionde kvinna att insjukna under sin livstid. Överlevnaden efter bröstcancer är bland de högsta i världen i Sverige, med femårsöverlevnad på cirka 90%. För de kvinnor som diagnosticeras i Most patients with breast cancer present with low-risk tumors, node-negative disease, and excellent prognosis. For these patients, routine axillary nodal staging by sentinel lymph node biopsy (SLNB) has no therapeutic benefit. For patients with limited sentinel lymph node metastasis, completion axillary nodal dissection is controversial. Furthermore, those with heavy-burden metastasis could benefi
Implicit assumptions, approaches, rules and practices in teaching i.e. teaching and learning regimes (TLRs) are produced and reproduced (cf. Trowler & Cooper 2002) in the closest teaching environment, traditionally within a discipline. However, multidisciplinary programs implies that teachers from different disciplines and with different taken for granted assumptions, approaches and rules are Implicit assumptions, approaches, rules and practices in teaching i.e. teaching and learning regimes (TLRs) are produced and reproduced (cf.

For more than 30 years since it was first proposed by Harrington et al., the Theory of Characteristic Mode (TCM) has only been applied to perfect electric conductors (PEC), and more recently lossless dielectric materials. One key challenge in computing the characteristic modes (CMs) of non-PEC materials using the PMCHWT surface integral equation is the presence of internal resonances in the soluti
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into biorefineries they can be a keystone in a future bioeconomy based on renewable resources instead of fossil fuels. In order to achieve this, pulp mills have to close their loops
Macromolecular crowding in biological media is an essential factor for cellular function. The interplay of intermolecular interactions at multiple time and length scales governs a fine-tuned system of reaction and transport processes, including particularly protein diffusion as a limiting or driving factor. Using quasielastic neutron backscattering, we probe the protein self-diffusion in crowded a
This paper presents the first attempt to assess the wastewater treatment processes at the oil refinery sector in Kazakhstan and evaluate to what extent these processes follow international and national regulations regarding industrial waste water treatment. The assessment was performed considering wastewater discharge from refining processes at three factories in the country. While Kazakhstani env
An experimental test system including the oil circulation system and the gas circuit system has been designed and built to explore the effects of the lubricating oil flow rate on the performance of a single-screw compressor, used in a portable natural gas liquefaction process. Outlet pressure, outlet volumetric flow rate, volumetric efficiency, and specific power rate are the parameters for evalua
We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). A diverse set of process routes will be necessary to produce all intermediates and commercial products. In
Avloppsreningsverk som hanterar industriellt avloppsvatten ställs inför särskilda utmaningar, eftersom sammansättningen ofta varierar kraftigt och kan innehålla toxiska ämnen. Störningar i reningsprocessen kan därför leda till ökade utsläpp och betydande miljöpåverkan, vilket gör det avgörande att undvika sådana störningar. Avloppsreningsverket vid Perstorp industripark renar processavloppsvatten Wastewater treatment plants that treat industrial wastewater face particular challenges, as the composition is highly variable and often contains toxic compounds. Process disturbances can thus result in increased effluent loads and significant environmental impact, highlighting the importance of avoiding interference. The wastewater treatment plant at the Perstorp site treats industrial wastewater
1 2 This essay explores the ethics of everyday life living as a professional scientist in a now ongoing research project (named Pre-H) explicitly focused on user participation. The ethical system of philosopher-theologian K. E. Løgstrup (1905-1981) is applied, with a focus on the sovereign expressions of life, and used to interpret four professional scientists lived experiences. Løgstrup used his
