To identify the cause of edge waves and to minimize them, which are frequently occurring on the steel pipe manufacturing site, the shape of the edge part of skelp has been confirmed according to a design variable and operating condition. In particular, parametric studies were carried out on the variation in the thickness of skelp, tskelp, the roll gap between upper and bottom rolls, troll, at the forming stage 1, Forming 1, the roll shape, toffset, of the Forming 1, and the material property of skelp to study the generation of edge waves, because these parameters have been determined by field engineers extemporaneously without any physical estimation. For this purpose, the roll design and operating conditions used in the field were applied to the finite element analysis model, and the distribution of contact force between the rolls and skelp, and the distribution of effective plastic strain on the skelp were investigated. The fact that adjusting to tskelp and troll arbitrarily without changing to the roll shape can cause not only the edge waves but also the center waves, was carried out. Especially, the edge waves were reduced without the irregular contact pressure by changing the surface of the upper roll that is offset by target tskelp in the normal direction of the surface of the bottom roll in the Forming 1, when the target thickness is tskelp. Moreover, there is no significant difference in the vertical load applied to the rolls when high-strength steels are used or when low-strength steels are used, it is necessary to predict the local maximum and minimum of contact pressure between the skelp and rolls and the shape of the upper roll of the Forming 1 should be modified to decrease irregular contact pressure instead of any design modifications.

Study of equivalence classes of links up to n-moves plays an important role in the theory of invariants based on the skein relation and, in particular, skein modules. In this paper, we consider Nakanishi's 4-move conjecture [12]. The modification of the conjecture to 2-component link (homotopically trivial links) is a question proposed by Kawauchi [10]. We define a new invariant of links which is preserved by 4-moves and analyze its potential strength. In particular, we show that our invariant allows us to obtain results of [8, 9, 13] concerning 4-moves.

Using Chebyshev polynomials, C. Frohman and R. Gelca introduced a basis of the Kauffman bracket skein module of the torus. This basis is especially useful because the Jones–Kauffman product can be described via a very simple Product-to-Sum formula. Presented in this work is a diagrammatic proof of this formula, which emphasizes and demystifies the role played by Chebyshev polynomials.

Denne artikel giver et overblik over morfemets rolle i menneskelig sprogprocessering på basis af teoretisk morfologi, psykolingvistik og undersøgelser af dansk ordgenkendelse. Jeg beskriver først hvordan teoretisk morfologi arbejder ud fra enten morfembaserede eller ordbaserede modeller, trods problemer med både morfemet og ordet som teoretiske størrelser. Efterfølgende ser jeg på to relaterede men dog adskilte psykolingvistiske traditioner der begge fokuserer på morfologi: for det første den såkaldte datidsdebat der står mellem på den ene side modeller der skelner skarpt mellem regelmæssige og uregelmæssige ord, og på den anden side modeller der postulerer den samme processeringsmekanisme for alle typer ord; for det andet en bredere ordgenkendelseslitteratur der, i modsætning til datidsdebatten og dens fokus på engelske bøjningsformer, undersøger forskellige sprog og forskellige typer morfologi. Dernæst opsummeres resultaterne fra en række eksperimenter om dansk ordgenkendelse som overordnet set tyder på en funktionel rolle for morfologien. Samtidig viser forskelle mellem forskellige typer ord, komplekse frekvenseffekter og effekter af det lydlige signals overlap med andre ord i sproget et komplekst billede af morfologiens rolle. Til slut opsummeres morfologiens funktionelle rolle i sprogprocesseringen, og de videre perspektiver opridses med en opfordring til et kritisk blik på psykolingvistikkens traditionelle metoder og på både ordet og morfemet som teoretiske størrelser.

AbstractWe study the problem of the amplification of an ultra-short seed pulse via stimulated Raman backscattering (SRB) from a long pump pulse (assumed to have an envelope with a constant amplitude), in an underdense plasma. The SRB interaction couples the pump light wave to a daughter light seed wave propagating in the opposite direction, scattered off an electron plasma wave. In recent numerical simulations, it has been observed that besides stimulated Raman backward scattering (SRBS) and stimulated Raman forward scattering, other high-frequency kinetic instabilities can occur when modified distribution functions exist during the evolution of the system. In particular, we showed the prominent role played by kinetic electrostatic electron nonlinear (KEEN) waves (Afeyan et al., 2004). We continue this work by applying a relativistic Vlasov–Maxwell code to study stimulated KEEN wave scattering (SKEENS) and its role in the SRBS short pulse amplification processes. An analysis of the full spectrum of waves participating in the amplification processes is presented. The absence of spurious noise in grid-based Vlasov codes allows us to follow the evolution of the system with a kinetic (collisionless) description. This affords us a glimpse at the intricate phase-space structures such as trapped particle orbits, which coexist and interact nonlinearly in the electron distribution function.

Brazilian discussions of race between 1880 and 1940 were partly a use of European scientific theory to rationalise the native system of colour discrimination. When scientific orthodoxy turned against ‘race’ between 1920 and 1945, much of the intellectual racism of Brazil also dispersed. Quite rightly, most intellectual histories of race in Brazil stress a disjuncture around 1930. However, from the 1870s onward, and most clearly after abolition, there was also a medical-psychiatric strand to ‘race’ that can be unravelled from the rest of the skein. Part of racial thinking in Brazil reflected the general medicalisation of social thought that began when early-nineteenth-century physicians called for hygienic reforms within upper-class families to protect children from hereditary or environmental contaminations. The Spencerian and Comtean positivist social science that became fashionable in Brazil after 1870 also contributed to medicalisation. It saw society as an organism, and compared the role of the social scientist to the role of the physician: to examine symptoms of disease and propose therapies. From the 1880s through the 1920s, the national ailment that the medicalised social thought of Brazil most often diagnosed, an ailment that connected individual health to national well-being, was degeneration.

Human cytomegalovirus (HCMV) UL53 belongs to a family of conserved herpesvirus genes. In this work, the expression and localization of the UL53 gene product was analysed. Results obtained showed that pUL53 is a new structural protein. In infected human fibroblasts, pUL53 localizes in cytoplasmic perinuclear granular formations together with other structural viral proteins. In the nucleus, pUL53 forms patches at the nuclear periphery and co-localizes with lamin B at the internal nuclear membrane level. Immunoelectron microscopy studies have disclosed that nuclear pseudo-inclusions are labelled, whereas nucleocapsid formations within the intranuclear skein are negative. Furthermore, the mature virus particle maintains pUL53 at its tegumental level. These data suggest that pUL53 could be involved either in nucleocapsid maturation or in the egress of nucleocapsids from the nucleus to the cytoplasm through the nuclear membrane, a role compatible with the function hypothesized for UL31, its positional homologue in herpes simplex virus type 1.

Cryptography has distinct paramount significance in interconnected environment where whether we concern about ‘Computer-Security,’ ‘Information-Security,’ ‘Network-Security’ etc., doesn’t matters and, ingredients of this particular branch of computer science viz. ‘Encryption/Decryption’ systems, ‘Hash-Functions,’ ‘Digital-Signatures’ etc. also playing vital role from years in order to manage ‘Confidentiality,’ ‘Integrity’ and ‘Authenticity’ of resources. The Encryption/Decryption Cryptosystems managing the Confidentiality and Hash-Functions are fully devoted towards to look after the Integrity, Authenticity either alone or with Digital Signature schemes. There is a huge list of ‘Hash-Algorithms’ available with us to provide dedicated services (i.e., security) depends on how complex is to break it. Few renowned names are MD5, Blake, CRUSH, Grøstl, HAIFA, JH, Lake, SHA, Skein, Whirlpool etc., Keyed/Un-keyed constructions having its own justifiable capabilities. So in this direction we’re proposing a new secure keyed Hash-Function especially for military services where security is major concern apart from resource utilization which not only fulfilling basic properties but also providing justifiable services in order to manage integrity/authenticity of resources.

The famous acoustics of ancient Greek theatres rely on a successful combination of appropriate location and architectural design. The theatres of the ancient world effectively combine two contradictory requirements: large audience capacity and excellent aural and visual comfort. Despite serious alterations resulting from either Roman modifications or accumulated damage, most of these theatres are still theatrically and acoustically functional. Acoustic research has proven that ancient theatres are applications of a successful combination of the basic parameters governing the acoustic design of open-air venues: elimination of external noise, harmonious arrangement of the audience around the performing space, geometric functions among the various parts of the theatre, reinforcement of the direct sound through positive sound reflections, and suppression of the delayed sound reflections or reverberation. Specifically, regarding the acoustic contribution of the stage building, it is important to clarify the consecutive modifications of the skene in the various types of theatres, given the fact that stage buildings were almost destroyed in most ancient Greek theatres. This paper attempts to demonstrate the positive role of the scenery in contemporary performances of ancient drama to improve the acoustic comfort using data from a sample of twenty (20) ancient theatres in Greece.

In his article “Fides et Ratio” (Philosophia Reformata 2000, 65: 72-104), Eduardo Echeverria states he is writing out of his concern that since “”¦ the lack of unity among Christians represents the grave obstacle for the proclamation of the gospel, we should take every suitable opportunity to increase the unity of all Christians. The present essay is meant as a contribution toward this goal.” (p.72). The increased unity he has in mind is a reconciliation of the traditional scholastic interpretation of Christian doctrine (which he designates the “TSC”), and the Calvinist tradition (which I will designate the “CT”). More specifically, he seeks a unity between them concerning the relation of faith and reason, that is, the role of reason in belief in God. To this end he compares what he understands of the CT, as represented by Calvin and Dooyeweerd, with the TSC as represented by St Thomas and the encyclical, Fides et Ratio (1998) by Pope John Paul II. In all that follows I will be agreeing with Echeverria that this is, indeed, an important concern and a laudable goal, and I hope that what I offer here in reply to his essay will be taken in that same charitable spirit. So even though I find that Echeverria’s account of the differences between the TSC and the CT is seriously mistaken, I do agree that it would go a long way toward greater cooperation between our two traditions if we could at least agree on what our differences are and work toward resolving them. For that reason I will be more concerned here with clarifying those differences than with arguing for the CT. That does not mean that I will not at times offer brief accounts of why I think the CT is right to differ from the TSC on certain points; it only means that I do not regard the case I will make for these points as anywhere near complete. This brevity is made necessary because I find the misunderstandings of Calvin, and especially of Dooyeweerd, to be so many and so knotted in “Fides et Ratio” as to form a tangled skein that would require more than just one article to unravel. I have also decided that there are so many strands to this skein that for the sake of clarity I will restrict myself to only a few of them. My assumption is that it would be better to make real progress with getting a few key differences in focus, than to end up producing a tangle of my own in an attempt to cover every point raised in Echeverria’s long article. My hope is that the treatment of the points I do cover will be sufficient to indicate how a more thorough untangling would proceed.

The French reception of Wagner is often based on the two pillars of the 1861 Tannhäuser production and that of Lohengrin in 1891. Sufficient is now known about the composer's earliest attempt to engage with Parisian music drama around 1840 to be able to understand his work on Das Liebesverbot, Rienzi, Der fliegende Holländer, his editorial and journalistic work for Schlesinger, and his emerging relationship with key figures in Parisian musical life, Meyerbeer most notably. A clearer picture is also beginning to emerge of Wagner's position in French cultural life and letters in the 1850s. Wagner's position in Paris during the 1860s, culminating in the production of Rienzi at the Théâtre- Lyrique in 1869, is however complex, multifaceted, and little understood. Although there were no staged versions of his operas between 1861 and 1869, the very existence of a successful Parisian premiere for an opera by Wagner in 1869—given that there would be almost nothing for two decades after 1870—is remarkable in itself. The 1860s furthermore saw the emergence of a coherent voice of Wagnérisme, the presence of French Wagnéristes at the composer's premieres all over Europe and a developing discourse in French around them. This may be set against a continuing tradition of performing extracts of Wagner's operas throughout the 1860s, largely through the energies of Jules Pasdeloup, who—as director of the Théâtre-Lyrique—was responsible for the 1869 Rienzi as well. These competing threads in the skein of Wagner-reception in the 1860s are tangled in a narrative of increasingly tense Franco-German cultural and political relationships in which Wagner, his works, and his writings, played a key role. The performance of Rienzi in 1869 was embedded in responses to the Prussian-Austrian War of 1866, the republication of Das Judenthum in der Musik in 1869, and the beginnings of the Franco-Prussian War.

The Na+/H+ exchanger is a ubiquitous, integral membrane protein involved in pH regulation. It removes intracellular acid, exchanging a proton for an extracellular sodium ion. There are seven known isoforms of this protein that are the products of distinct genes. The first isoform discovered (NHE1) is ubiquitously distributed throughout the plasma membrane of virtually all tissues. It plays many different physiological roles in mammals, including important functions in regulation of intracellular pH, in heart disease, and in cytoskeletal organization. The first 500 amino acids of the protein are believed to consist of 12 transmembrane helices, a membrane-associated segment, and two reentrant loops. A C-terminal regulatory domain of approximately 315 amino acids regulates the protein and mediates cyto skel etal interactions. Studies are underway to determine the amino acid residues important in NHE1 function. At present, it is clear that transmembrane segment IV is important in NHE1 function and that transmembrane segments VII and IX are also involved in transport. Further experiments are required to elucidate the mechanism of transport and regulation of this multifunctional protein.Key words: cation transport, intracellular pH, membrane proteins, Na+/H+ exchanger.

Den høje danske dimittendalder har været et tilbagevendende indslag på den politiske dagsorden i de sidste 10 år. Forskningsmæssigt ved vi dog ikke så meget om årsagerne, og især sammenhængen mellem social baggrund og de studerendes alder er underbelyst i en dansk kontekst. I internationale undersøgelser peger resultaterne på, at der er en mindre socialt skæv rekruttering blandt ældre end yngre studerende. Denne artikel undersøger, om dette også er gældende for danske forhold. Ved at skelne mellem dimittendalder og sabbat byder artiklen på ny viden om, hvor i uddannelsesforløbet betydningen af social baggrund er størst. Desuden analyseres studerendes egne begrundelser for at holde pauser mellem uddannelser, hvilket normalt ikke indgår i de internationale undersøgelser på feltet. Resultaterne viser, at der er en sammenhæng mellem social baggrund og dimittendalder. Unge med højtuddannede, højtlønnede gifte/samlevende forældre bosat i storbyer har markant lavere dimittendalder end unge med lavtuddannede, lavtlønnede enlige forældre bosat på landet. I forhold til sabbat efter gymnasietiden lader der derimod til at være en homogenitet blandt de unge, da varigheden af pauser ikke varierer nævneværdig med social baggrund. Der er heller ingen signifikante forskelle mellem studerende med forskellig social oprindelse i begrundelserne for sabbat. ENGELSK ABSTRACT: Rolf Lyneborg Lund and Trond Beldo Klausen: A Long Way to Go: Social Background and Students’ Age at Danish Universities The high age at graduation of Danish university students has been on the political agenda during the last decade. International research has shown that mature students are a less socially selected group than younger students, but virtually nothing is known about social origin and students’ age in Denmark. This article investigates the association between social origin and students’ age based on data from administrative registers. This data allows us to differentiate between graduation age and gap years. A framework of social inequality is used to analyze students’ own reasons for choosing gap years, which is contrary to most research in this field. The results show a fairly strong association between social origin and graduation age. Descendants of urban living highly educated married parents with high earnings are more likely to attain a master’s degree at a younger age than decedents of rural living single parents with low education and low earnings. However, there is virtually no significant association between social origin and gap years, and the reasons for choosing to have one or more gap years do not vary between students of different social origin. Keywords: graduation age, gap years, higher education, social inequality, social class.

The article discusses Badiou’s reading of Paul. Although it would be easy to criticise it on the basis of its overly anachronistic character, I argue that there may be more to it. I present his reading and situate it in the framework of his wider philosophical oeuvre. Core issues are the ideas of anti-philosophy, subjectivity, the event, the fabulous, singularity, universalism, and love. I accentuate Badiou’s use of Paul as exemplary of a post- and anti-Nietzschean philosophical undertaking. Four critical points are raised against Badiou’s use of Paul: (1) a lack of historical appreciation of the type of religion Paul represents. Had Badiou acknowledged the Axial Age character of Paul’s religiosity, he could have strengthened his argument by undergirding it historically; (2) a problematic element of anti-Judaism relating to the juxtaposition of Pharisees with Pétainists; (3) although Paul may be seen to revolt against one particular type of particularism, it is difficult to see how one can possibly surmise that Paul’s worldview and the role he ascribes to Christ-adherents can evade the accusation of exemplifying another form of particularism; (4) throughout Badiou’s reading, there is a lack of lucidity in the use of concepts and in the ductus of the philosophical argument. At points, the argument borders mysticism and religious discourse. Artiklen giver en introduktion til den franske filosof Badious Paulus-læsning og placerer den i sammenhæng med hans øvrige filosofiske oeuvre. Jeg fremdrager en række centrale begreber i såvel hans Paulus-læsning som i hans filosofi generelt. Det gælder betoningen af det subjektive og subjektet, begivenheden, det fabuløse, det singulære, antifilosofi, universalisme og kærlighed. Jeg fremhæver Badious Paulus-læsning som udtryk for en post- og anti-nietzscheansk tænkning. Fire grundlæggende kritikpunkter kan rettes mod læsningen: 1) manglende sans for Paulus’ religionstype. Havde Badiou været bevidst om Paulus’ aksialreligiøse verdensforståelse, ville han dels have kunnet underbygge sin læsning historisk, dels have nuanceret forbindelsen til Nietzsche; 2) en antijudaisme hos Badiou udtrykt i sidestillingen mellem farisæere og pétainister; 3) mangel på forståelse i skelnen mellem singularitet og partikularisme for det paulinske verdenssyns partikularisme. Sans for Paulus’ aksialitet ville have åbnet Badious øjne for, at Paulus’ opgør med en type partikularisme ikke fjerner ham fra identitetsfiksering. Den transponeres i stedet fra en etnicitetsbaseret til en fideistisk grundet religion; 4) et uklarhedsproblem i Badious filosofi, som er essayistisk, fabulerende og ugennemsigtig i begrebsbrug og argumentationsgang. Derved forsynder den sig mod grundlæggende dyder i al filosofisk argumentation.

Udgangspunktet for denne artikel er, at humor spiller en relativt dominerende rolle i dansk tv-reklame, og at der dermed er tale om en stilart, som i høj grad søger at vinde tilslutning og sympati igennem en inkluderende henvendelsesmodus. Man kunne fristes til at antage, at dette skulle hænge sammen med en særlig dansk mentalitet, og at humor er mere eller mindre uomgængelig, hvis man vil have danske forbrugere i tale. Dette forhold kontrasteres med den tænkning i livsstile, som er blevet dominerende, dvs. en tænkning, der grundlæggende søger at udskille bestemte forbrugertyper eller -grupper og altså grundlæggende skiller eller ekskluderer i segmenter, målgrupper og værdifællesskaber og dermed i princippet også dikterer en udformning af kommunikationen, der sætter skel. Artiklens pointe er, at humor i flere henseender kan være en pragmatisk måde at omgå en række af de problemer, som såvel tænkning i livsstilssegmenter som i unikke mærkevarer sætter vis-a-vis et forholdsvist lille markedsområde, hvor kontakt via tv-reklame kan være relativt dyr. Og at humor bl.a. kan gøre det i kraft af, at dens særlige tvetydige modus forrykker kommunikationens realitetsreference til et andet plan og/eller til andre mere eller mindre groteske og derealiserede universer og figurer/figurkonstellationer. Det markeret forrykte kan dermed udgøre et fælles ’neutralt’ felt, som uanset skillelinjer i livsstile mv. kan appellere bredt og fungere inkluderende. Humour in Danish TV advertising. A means of transcending lifestyle barriers? The point of departure for the article is the fact that approximately 40% of Danish TV advertising in the 1990s had some humorous content and that fictional formats such as drama (and comedy) play an increasing role (cf. Stigel 2006 and 2001). Both small scale and large scale humour play a great role in Danish TV-ads and you might presume that this is due to some kind of special Danish mentality that one has to conform to in order to reach a Danish audience. Although humour in general has many faces the humorous style in Danish TV-ads is typically one of good will and seldom one of offensiveness. The intention is to include and create common ground in a playful way. In contrast the concept of lifestyle is basically a way of construing and segmenting audiences that prescribes exclusion and distinction or at least underlines barriers and differences between groups of people, their values and mentalities and accordingly also manifests these differences in the mode of address and the style of execution. The point the article makes is that humour in several respects represents a pragmatic way, making it possible to by-pass or transcend some of the problems raised by segmentation, lifestyle and unique brands - especially in a relatively small (Danish) market. The ambiguous mode of humour displaces the facts and the reality referred to by lifting things up to another (playful) level and/or by staging them via more or less grotesque events and non-realistic characters and universes. The displacement makes up a common, ’neutral’ ground and a marked level of incongruence in which it is possible to cross borders of lifestyle as well as other borders and problems inherent in marketing communication and consequently appeal in a broader and more inclusive way.

This time last year, I was contemplating the predictions of Nostradamus, the possibility of a ‘barbeque summer’, and the hope that an Olympic ‘feel good factor’ would find its way onto the AMU. Longterm predictions are as tough for clinicians as they are for weathermen and 14th century apothecaries, but even looking a few days into the future can be difficult. In some ways it is the unpredictability of acute medicine which provides our biggest challenges: risk scores, early warning scores, and discharge prediction tools attempt to add some science to the subjectivity of clinical assessment. Every scientific meeting seems to feature a new biomarker, promising to eliminate uncertainty and improve accuracy, but probably opening a few cans of worms in the process. None of us has a crystal ball; recognising uncertainty – and communicating this to our patients – is a key skill which we all need to develop. The challenge of delivering a high quality acute medicine service, 7 days a week, has been a major theme for 2012. Many readers will already have read the ‘Toolkit’ for delivery of a 7 day consultant service on the AMU, produced by the Royal College of Physicians (RCP) in association with SAM. This can be downloaded from the SAM website (www.acutemedicine.org.uk) along with the AMU Quality Standards which were released earlier in the summer. The article by Hannah Skene and David Ward on p205 complements these two documents, highlighting some of the practicalities in implementing quality standards across the 7 day week. This paper also comments on best ward round practice, a topic which has been the subject of some combined work by the RCP and Royal College of Nursing this year, and which provided the subject of the ‘best poster’, awarded to John Soon at this year’s SAM Autumn conference. The abstract from this presentation is included in the ‘selected abstracts’ article on p217. During the summer I had the privilege to represent SAM at a reception organised by SepsisUK to co-incide with World Sepsis Day. The event featured some powerful, and moving talks from patients and relatives affected by sepsis, portraying the importance of early diagnosis and treatment for this devastating condition. Case reports in this journal over the past 10 years have demonstrated how often acute physicians are faced with atypical presentations of infection; this is particularly true for older patients as demonstrated in the cases on p 226. Ron Daniels’ ‘viewpoint’ article emphasises the important role which acute physicians have in recognising the signs of sepsis, ensuring early treatment and escalation to higher dependency areas where necessary. For patients who do not fall into any other clear cut speciality category during the first 48 hours of their hospital stay, acute physicians must provide the leadership and continuity of care which are essential in ensuring a good outcome. January is a busy time on the AMU, so wishing you all a ‘Happy New Year’ may seem inappropriate to some readers. As I mentioned at the top of this editorial, my track record in prediction has not been good lately; however I hope it’s a fairly safe bet to suggest that – no matter how hard these next few weeks may get – the months which follow will probably be a whole lot easier!

ABSTRACT Gibberellin (GA) phytohormones are ubiquitous regulators of growth and developmental processes in vascular plants. The convergent evolution of GA production by plant-associated bacteria, including both symbiotic nitrogen-fixing rhizobia and phytopathogens, suggests that manipulation of GA signaling is a powerful mechanism for microbes to gain an advantage in these interactions. Although orthologous operons encode GA biosynthetic enzymes in both rhizobia and phytopathogens, notable genetic heterogeneity and scattered operon distribution in these lineages, including loss of the gene for the final biosynthetic step in most rhizobia, suggest varied functions for GA in these distinct plant-microbe interactions. Therefore, deciphering GA operon evolutionary history should provide crucial evidence toward understanding the distinct biological roles for bacterial GA production. To further establish the genetic composition of the GA operon, two operon-associated genes that exhibit limited distribution among rhizobia were biochemically characterized, verifying their roles in GA biosynthesis. This enabled employment of a maximum parsimony ancestral gene block reconstruction algorithm to characterize loss, gain, and horizontal gene transfer (HGT) of GA operon genes within alphaproteobacterial rhizobia, which exhibit the most heterogeneity among the bacteria containing this biosynthetic gene cluster. Collectively, this evolutionary analysis reveals a complex history for HGT of the entire GA operon, as well as the individual genes therein, and ultimately provides a basis for linking genetic content to bacterial GA functions in diverse plant-microbe interactions, including insight into the subtleties of the coevolving molecular interactions between rhizobia and their leguminous host plants. IMPORTANCE While production of phytohormones by plant-associated microbes has long been appreciated, identification of the gibberellin (GA) biosynthetic operon in plant-associated bacteria has revealed surprising genetic heterogeneity. Notably, this heterogeneity seems to be associated with the lifestyle of the microbe; while the GA operon in phytopathogenic bacteria does not seem to vary to any significant degree, thus enabling production of bioactive GA, symbiotic rhizobia exhibit a number of GA operon gene loss and gain events. This suggests that a unique set of selective pressures are exerted on this biosynthetic gene cluster in rhizobia. Through analysis of the evolutionary history of the GA operon in alphaproteobacterial rhizobia, which display substantial diversity in their GA operon structure and gene content, we provide insight into the effect of lifestyle and host interactions on the production of this phytohormone by plant-associated bacteria.

In a very literal sense, a biological organism cannot be alive on its own. I employ key premises in second-order cybernetics in current developments in philosophy of science and posthumanist thought in an attempt to speak upon the state of precarity and lived reality of social and political life during the unprecedented COVID-19 pandemic. I posit the parasite and the virus as biological and communicational forms which model the impossibility of solipsism in life (be it viral, parasitic, or human). I believe that disrupting a premise of solipsism operates as a central task in an attempt to see and speak of the skein of interrelationships that inform our shared understanding about current events. To mobilize this discussion, I am sensitized to seek the resonances of the film Parasite on topics of radical interrelationality, systemicities within capitalist strictures, and muddled boundaries of biological and political life. The role of socio-economic boundaries affectively felt in the film provides a starting point from which I delve into analogous scientific concepts, including work of cyberneticians Gregory Bateson and Heinz von Foerster, among others, and their respective notions of epistemological responsibility and the circularity of human relations and mutual interaction. This discussion will anchor my attempt to present a symbiosis of concepts that posit the existence of viruses as the existence of boundaries in life forms on earth. Such concepts include Jakob von Uexküll’s Umwelt especially as it pertains to viral life, Michel Serres’ malleable interpretation of the parasite, and the formal analogies made by cyberneticists between viral ‘consciousness’ and Alan Turing’s machine (self-)organization. I frame these concepts with their potential to offer a phenomenologically resonant and scientifically nuanced understanding into systemic class warfare in mind, as depicted in the film and ramifying throughout.

I disse år er både i Danmark og internationalt fokus på, hvordan læreruddannelsen på den ene side kan blive mere forskningsbaseret og på den anden side forbindes tættere til praksis. Dette fokus bygger på en forestilling om, at forskningen yder et vigtigt bidrag til uddannelsen af kommende folkeskolelærere, men også at denne forskning skal være koblet stærkt til praksis, og at den skal kunne formidles til både skolens praksis og uddannelsen. Med andre ord ekspliciteres en bestemt forestilling om, hvad forskning er og skal. I artiklen udfordres denne grundlæggende forståelse af, hvad forskning i en læreruddannelseskontekst er og skal være, og der peges på et transformatorisk forskningsbegreb der skelner mellem teori, empiri og praksis. Gennem erfaringer fra forsknings- og skoleudviklingsarbejde i Universitetsskolen vises hvordan studerende, lærere og læreruddannere gennem refleksive og transformative processer mellem teori, empiri og praksis får en mere nuanceret forståelse for skolens og uddannelsens praksis. Nøgleord: læreruddannelse, praksissamarbejde, forskningsbasering, forskningsbegreb, teori–praksis “The University School” – a suggestion of a more didactically oriented concept of research AbstractIn Denmark as well as internationally, there is increasing focus on how teacher education can become on the one hand more research-based, and on the other, more closely linked to practice. This is based on the notion that research provides an important contribution to the education of future primary school teachers, while such research must be strongly linked to practice and at the same time communicable to the school, both in practice and for educational purposes. In other words, a certain idea of what research is, and which purpose it holds, is explicated. In this article, the basic understanding of the role and purpose of research in the context of teacher education is challenged, and a transformatory concept of research is outlined – one that distinguishes between theory, empirical data, and practice. Through experience from research and developmental work in the schools participating in “The University School”, students, teachers, and teacher educators are shown ways to develop a more nuanced understanding of school practices and education through reflexive and transformative processes between theory, empirical data and practice. Keywords: teacher education, practice collaboration, research-based, concept of research, theory–practice

Current research into regeneration of the nervous system has focused on defining the molecular events that occur during regeneration. One well-characterized system for studying nerve regeneration is the sciatic nerve of rat. Numerous studies have characterized the sequence of events that occur after a crush injury to the sciatic nerve (Cajal 1928; Hall 1989). These events include axon and myelin breakdown, changes in the permeability of the blood vessels, proliferation of Schwann cells, invasion of macrophages, and the phagocytosis of myelin fragments by Schwann cells and macrophages. The distal segment of the injured sciatic nerve provides a supportive environment for the regeneration of the nerve fibres (Cajal 1928; David & Aguayo 1981). Within a period of weeks, the injured sciatic nerve is able to regrow and successfully reinnervate the appropriate targets. Some of the molecules that provide trophic support for the regrowing nerve fibres have been identified, including nerve growth factor (NGF) (Heumann et al. 1987) and glial maturation factor beta (Bosch et al. 1989). Another class of molecules show changes in their rates of synthesis during regeneration, including both proteins (Skene & Shooter 1983; Muller et al. 1986) and mRNA species (Trapp et al. 1988; Meier et al. 1989). To better understand nerve regeneration, we have taken two, parallel molecular approaches to study the events associated with regeneration. The first of these is to study in detail the mechanism of action of a molecule that has been implicated in the regeneration process, nerve growth factor. The second approach is to identify novel gene sequences which are regulated during regeneration. Once the genes are isolated, it will be possible to test for functional roles of the encoded proteins during regeneration. Results from the two approaches are presented in this paper.

The Nass River discharges into Nass Bay and Iceberg Bay, which are adjoining tidal inlets located within the northern inland waters of British Columbia, Canada. After the Skeena River, the Nass River is the second longest river within northern British Columbia, which discharges directly into Canadian waters of the Pacific Ocean. It is also supports one of the most productive salmon fisheries in northern British Columbia. The Nass River discharges into the eastern end of Nass Bay. Nass Bay, in turn feeds into Portland Canal and the fresh surface waters then flows westward to the Pacific Ocean via Dixon Entrance. The tides in Northern British Columbia are very large with a tidal height range of just over 7 m. Nass Bay is a shallow inlet of less than 10 km in length with typical water depths of than 10 m or less. The existing knowledge of oceanographic processes in Nass and Iceberg Bays was rudimentary until three years ago, when the first modern oceanographic measurements were obtained. In this study, the seasonal and tidal variability of the lateral extent of the Nass River surface plume is mapped from analyses of Landsat satellite data spanning the period from 2008 to 2015. A high resolution coupled three dimensional (3D) hydrodynamic model was developed and implemented, within the widely used and accepted Delft3D modeling framework, which was forced and validated using recent 2013-2016 in-situ oceanographic measurements. The combined satellite and numerical modeling methods are used to study the physical oceanographic and sediment transport regime of Nass and Iceberg Bays and the adjoining waters of Portland Inlet and Observatory Inlet. The ocean circulation of Nass and Iceberg Bays was found to be dominated by tidal currents, and by the highly seasonal and variable Nass River freshwater discharges. Complex lateral spatial patterns in the tidal currents occur due to the opening of the southwestern side of Nass Bay onto the deeper adjoining waters of Iceberg Bay. Surface winds are limited to a secondary role in the circulation variability. The sediment dynamics of the Nass Bay system features a very prominent surface sediment plume present from the time of freshet in mid-spring through to large rainfall runoff events in the fall. The time-varying turbidity distribution and transport paths of the Nass River sediment discharges in the study area were characterized using the model results combined with an analysis of several high-resolution multi-year Landsat satellite data sets.
