We have implemented and evaluated a secondary organic aerosol scheme within the chemistry transport model TM5-MP in this work. In earlier versions of TM5-MP the secondary organic aerosol (SOA) was emitted as Aitken-sized particle mass emulating the condensation. In the current scheme we simulate the formation of secondary organic aerosol from oxidation of isoprene and monoterpenes by ozone and hyd

Background: Lund is one of the two tertiary referral centers for pediatric cardiac surgery in Sweden, with nearly 350 surgical procedures every year. We performed a retrospective analysis of newborns and infants with transposition of the great arteries (TGA) operated with arterial switch (ASO) during the past 10 years. Methods: a single-institution retrospective analysis of nearly 100 newborns and

Rotor-stator mixers (RSMs) can be operated in either batch or inline mode. When operating a rotor-stator geometry in batch mode, it typically experiences an order of magnitude higher volumetric flow through the stator than in inline mode. This is expected to cause differences in the flow and turbulence in the rotor-stator region. This study uses computational fluid dynamics (CFD) to study the hydr
Mycoprotein from the fungi Fusarium Venenatum A3/5 has been used as a meat alternative for a long time but little attention has been paid to the waste it creates. When the fungi is fermenting it uses a lot of water which is sent to the drain after the process is finished. This water contains large quantities of both nutrients and biomass. As circular economy is becoming more important for environm
In transposition of the great arteries (TGA), certain coronary patterns have been associated with major adverse events early after the arterial switch operation (ASO). We sought to determine the impact of preoperative echocardiographic (ECHO) diagnosis on the intra and postoperative morbidity. All patients with TGA born between June 2001 and June 2017 and who underwent ASO were reviewed. Data on
Popular Abstract in English News about global warming, discussions about alternative fuels such as natural-gas and biogas, and commercials about gas engines sound familiar to the most people living in modern societies. Why global warming is important? What is the role of natural-gas engines in this subject? Are natural-gas engines efficient? Do they perform as well as diesel engines? If not, why? Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels. Using natural gas/biogas can be a very good alternative due to the attractive fuel properties regarding emissio
In this two-part paper, influences from environmental factors on lightning in a convective storm are assessed with a model. In Part I, an electrical component is described and applied in the Aerosol-Cloud model (AC). AC treats many types of secondary (e.g., breakup in ice-ice collisions, raindrop-freezing fragmentation, rime splintering) and primary (heterogeneous, homogeneous freezing) ice initia
Within Scania there is a need to classify vehicles depending on the prevailing operation conditions. Different vehicles are exposed to various loads and this will influence the need for R&M greatly. The systems that are presently used for classification purposes are subjective and the owner’s negotiation skills can affect the outcome. Simultaneously there is a lack of knowledge concerning the
Catalyst from a Perstorp Formox formaldehyde plant, operating with high inlet concentration of methanol (10.2 vol.%), was discharged from single tubes of a multi-tube reactor after half the expected lifetime of the catalyst and again after termination of the load. Each tube was filled with two different layers of catalyst. From the inlet of the reactor the first layer was a catalyst mixed with ine
Interfacial stability issues at the cathode remain a bottleneck to developing durable and high-power all-solid-state lithium batteries (ASSLBs). In fact, the presence of conductive carbon in the cathode, necessary for high capacity and power capability, is believed to aggravate the stability woes. Thus, it is typically excluded from the cathode mix. Herein, employing a model functionalized ca
Thanks to an intensive technological effort in the framework of the EUFELE collaboration, the European FEL at ELETTRA was able to break the previous record for the shortest wavelength of an FEL oscillator. Novel solutions were adopted for multilayer mirrors to allow FEL operation in the wavelength region between 160 and 190 nm, which is one of the main targets of the project. The characteristics o
This study aims to investigate the environmental, operational and economic performance of the methanol partially premixed combustion concept at slow speed operation of a ship to find a solution for the shipping emission effect on the coastal settlements while do not increase the risk and expense of the engine operation on the ships. The experimental study was done with partially premixed combustio
The purpose of this article is to describe three cases of kissing stent placement in the common femoral artery bifurcation in patients unsuitable for open endarterectomy and patch plasty. In three patients with critical limb ischemia, caused by primary atherosclerotic disease or dissection-related injury when performing a lower extremity intervention, a technique of kissing stents was used to trea
In Southern Sweden, production of renewable energy from crop residues digestion is viewed as a worthwhile alternative. Also, the process gives valuable mineralised nitrogen as a by-product, which when produced at farm-scale can be recycled for ecological farming. It is difficult to achieve economic utilisation of crop residues in centralised slurry digestion, mainly because of the greater transpor
