Hadronic resonances are used to probe the hadron gas produced in the late stage of heavy-ion collisions since they decay on the same timescale, of the order of 1–10 fm/c, as the decoupling time of the system. In the hadron gas, (pseudo)elastic scatterings among the products of resonances that decayed before the kinetic freeze-out and regeneration processes counteract each other, the net effect dep
Standards are put forward as important means to turn the ideals of ethical and responsible artificial intelligence into practice. One principle targeted for standardization is transparency. This article attends to the tension between standardization and transparency, by combining a theoretical exploration of these concepts with an empirical analysis of standardizations of artificial intelligence t
Fluorescence, the optical phenomenon whereby short-wavelength light is absorbed and emitted at longer wavelengths, has been widely described in aquatic habitats, in both invertebrates and fish. Recent years have seen a stream of articles reporting fluorescence, ranging from frogs, platypus, to even fully terrestrial organisms such as flying squirrels, often explicitly or implicitly linking the pre
Planthoppers (Hemiptera: Fulgoromorpha) are a species-rich and globally distributed insect clade with high economic, ecological and evolutionary importance. However, the relationships among planthopper lineages and families remain unclear. Previous efforts based on inconsistent morphological traits, a few genes or limited sampling often resulted in conflicting tree topologies. Here, we used genome
The Warburg effect, which describes the fermentation of glucose to lactate even in the presence of oxygen, is ubiquitous in proliferative mammalian cells, including cancer cells, but poses challenges for biopharmaceutical production as lactate accumulation inhibits cell growth and protein production. Previous efforts to eliminate lactate production in cells for bioprocessing have failed as lactate
The procurement process can be defined as all the activities required in getting a product or a service from the supplier to a final destination. It encompasses the purchasing function, storing, transportation and manages the relations between suppliers and internal customers. It is a cyclical process involving the following activities: analysis, planning, implementation, and measurement. The perf
The international standard IEC 62264, also known as ISA95, deals with Enterprise-Control System integration and Manufacturing Operations Management. The standard contains, among other things, a description of what Manufacturing Operations means. The description states that The activities of manufacturing operations management are those activities of a manufacturing facility that coordinate the per
This article focuses on sustainability and environmental challenges in spa industry and describes motivations and possible barriers spas can face while addressing them. Environmental issues are gaining on importance for spa industry, as visiting spa becomes a popular leisure activity, leading to steady growth of the industry and increased public visibility. Spa companies are known to consume natur
Despite their tiny eyes and brains, nocturnal insects have remarkable visual abilities. Recent work-particularly on fast-flying moths and bees and on ball-rolling dung beetles-has shown that nocturnal insects are able to distinguish colors, to detect faint movements, to learn visual landmarks, to orient to the faint pattern of polarized light produced by the moon, and to navigate using the stars.
Life oil earth was formed during billions of years, exposed to, and shaped by the original physical forces such as gravitation, cosmic irradiation, atmospheric electric fields and the terrestrial magnetism. The Schumann resonances at 7.4 Hz are all example of oscillations possibly important for life.(1)) The existing organisms are created to function in harmony with these forces. However, in the l
Tidigare forskning som berör våldet under kriget i Bosnien och Hercegovina presenterar en ensidig bild av fenomenet ”krigsvåld.” Forskare har uppmärksammat betydelsen av efterkrigsberättelser, men de har inte uppmärksammat berättelser om krigsvåld, eller analyserat berättelserna om krigsvåld som en produkt av mellanmänsklig interaktion. Denna artikel försöker fylla denna kunskapslucka genom att anPrevious research on violence during the war in Bosnia and Herzegovina presents a one-sided picture of the phenomenon ”war violence.” Researchers have emphasized the importance of narratives but they have not focused on stories about war violence, nor have they analyzed the stories of war violence being a product of interpersonal interaction. This article tries to fill this knowledge gap by analyz
AIM: To evaluate the effect of hyaluronan (HY) application as monotherapy or as adjunct to non-surgical and/or surgical periodontal therapy. METHODS: Literature search was performed according to PRISMA guidelines with the following main eligibility criteria: (a) English or German language; (b) preclinical in-vivo or human controlled trials; (c) effect size of HY evaluated histologically or clinic
The Ax phenotype is an important subgroup of the ABO blood group system. Its inheritance does not always follow Mendelian rules and recent studies suggested that different alleles can result in this phenotype. This suggestion has been explored by cloning and sequencing exons 6 and 7 of the ABO gene and the intervening intron from members of six unrelated families expressing the Ax phenotype. Two f
Restenosis is a major problem after balloon angioplasty and stent implantation. The aim of this study is to introduce gadolinium neutron capture brachytherapy (GdNCB) as a suitable modality for treatment of stenosis. The utility of GdNCB in intravascular brachytherapy (IVBT) of stent stenosis is investigated by using the GEANT4 and MCNP4B Monte Carlo radiation transport codes. To study capture rat
Popular Abstract in Swedish Förståelse av väldigt snabba proceeser i molekyler utgör grunden inom modern kemi. Jonisation och excitation av en molekyl med en foton startar en nukleär dynamisk process som åtföljs av elektroniskt sönderfall och fragmentering av molekylen. En rörelsemändsvektor-spektrometer har utveclats som används för att mäta massa, laddning, energi och hastighet av joniska fragmeA momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. The possibility of focusing is essential for most applications, where fragment momentum is to be extracted. The apparatus
Enzyme engineering for a better future It is essential for many organisms on this planet to be able to digest plants. One of those organisms is the blue mussel, which uses certain enzymes in its stomach to break down sugar fibers in the algae that it eats. But how does this really work, and can we use it for anything? Plant cells have very strong walls, protecting them from environmental stress.
In today's industry the need for fast logging of measurements is increasing. Existing systems used by Tetra Pak AB have a maximum logging frequency which is inadequate. As a result of this Tetra Pak gave Industriprojektbyrån AB the task of developing a measuring system for this purpose. Industriprojektbyrån AB has before the start of this thesis developed the hardware set up for the system. Th
