Abstract:
Mens unges brug af billedmedier har fået megen opmærksomhed de senere år, er radioen blevet overset. Radioen er for de unge først og fremmest et musikmedie og er som sådan et af de vigtigste medier i de unges liv. Danmarks Radios Medieforsknings afdeling har gennem en kvalitativ analyse af de 16-19 åriges brug af radio, set i sammenhæng med uddannelse og musiksmag. For de unge bærer radioen både musikken og andre kulturelle signaler: Programværternes roller, præ- sentationsformerne osv.. Derfor kan musik og radio betragtes som en vigtig del af det kulturelle rum, hvor unge bearbejder hverdagslivets erfaringer og udtrykker deres identitet.

Abstract:
Due to the rapid growth in the use of wireless communication services and the corresponding scarcity and the high cost of radio spectrum bandwidth, Channel assignment problem (CAP) is becoming highly important. Radio [Formula: see text]-coloring of graphs is a variation of CAP. For a positive integer [Formula: see text], a radio [Formula: see text]-coloring of a simple connected graph [Formula: see text] is a mapping [Formula: see text] from the vertex set [Formula: see text] to the set [Formula: see text] of non-negative integers such that [Formula: see text] for each pair of distinct vertices [Formula: see text] and [Formula: see text] of [Formula: see text], where [Formula: see text] is the distance between [Formula: see text] and [Formula: see text] in [Formula: see text]. The span of a radio [Formula: see text]-coloring [Formula: see text], denoted by [Formula: see text], is defined as [Formula: see text] and the radio[Formula: see text]-chromatic number of [Formula: see text], denoted by [Formula: see text], is [Formula: see text] where the minimum is taken over all radio [Formula: see text]-coloring of [Formula: see text]. In this paper, we present two radio [Formula: see text]-coloring algorithms for general graphs which will produce radio [Formula: see text]-colorings with their spans. For an [Formula: see text]-vertex simple connected graph the time complexity of the both algorithm is of [Formula: see text]. Implementing these algorithms we get the exact value of [Formula: see text] for several graphs (for example, [Formula: see text], [Formula: see text], [Formula: see text], some circulant graph etc.) and many values of [Formula: see text], especially for [Formula: see text].

Abstract:
Previous researches on radio convergence showed that various radio stations in Ponorogo have implemented convergence by using new media platforms, such as, radio and video streaming, Youtube, and social media. However, evaluations on radio convergence has never been done before. Therefore, this research was conducted to study the effect of convergence to the listenership as well as to evaluate the implementation of radio-convergence in Ponorogo radio stations from April to July 2019. Using a survey method, the researchers administered a set of questionnaires to 267 respondents in Ponorogo to find out the listenership trends in Ponorogo community on its radio and other convergence platforms. The results of the study showed that the convergence implemented by the radios failed to raise awareness and number of radio listeners. Low awareness affects the community’s media habit. It was apparent in the fact that 84% of the respondents preferred conventional (analog) radio to a convergence platform. The results of this study also showed that convergence was unable to foster community involvement with radio. In other words, the radio was not the primary choice of the Ponorogo community in accessing information or entertainment.

Full text
Abstract:
Hercules A is an unusual radio source in that its structure is dominated (most specifically on the western side of the source) by an undulating chain of discrete "rings" of radio emission, whose individual radii increase progressively with distance from the nuclear core while their apparent separation decreases. In the theoretical model presented here, these interesting radio features are presumed to be due to emission from a discrete set of ram-pressure confined plasmoids that have been periodically ejected by a precessing nuclear engine. The predicted deceleration and expansion of these ram-pressure confined plasmoids provides an excellent fit to the observed spacing and radii of the radio rings observed on the western side of Hercules A. Furthermore, a satisfactory fit to the morphology of the undulating eastern jet can also be achieved using this discrete ejection model, providing the eastward ejections alternate with the westward ejections, thus implying a form of flip-flop behavior for this particular source.

We have begun VLA observations of straight-angle tailed radio sources (SATs) at 1.5 and 4.8 GHz (L and C band) to achieve one arcsecond resolution at each frequency. This will provide a SAT data set similar to the O'Donoghue, Owen, and Eilek (1990) WAT data set with both total intensity and spectral index information. We will use these data to examine morphological and dynamical properties of straight-tailed radio sources in clusters of galaxies.

Full text
Abstract:
The objective of this thesis was to evaluate radio receivers that had been previously acquired for other tasks by the Swedish Defence Materiel Administration, for additional service in a radio direction finding (DF) system. The antenna, calibration signal generator and DF algorithm were provided. As the receivers used the VITA 49 frame format, much of the work involved the interpretation of the frame structure and contents. The other main challenges were to put the receivers into the correct internal state, to compensate the analogue phase errors due to cabling, and to correlate the digital frames according to the time stamps. The work was performed partly as a literature study and, during implementation, by using an investigative trial and-error method. Collection of reference signals, for later offline analysis, was made at the Swedish Defence Research Agency. The findings of the evaluation was that the receivers were phase coherent and that the VITA 49 frame format was suitable for DF use. An apparently systematic error of unknown origin rendered the DF results inaccurate, even though the precision of the results was high. The automatic gain control (AGC) of the receivers did not perform according to norm. If the systematic error is compensated for, and the AGC problem is eliminated, the receivers will function as a DF system using the manufacturer's instructions, with the provided antenna. The performance of the receivers in this setting was not a primary concern for the thesis, but was deemed to be acceptable. Suggestions for further development include finding the source of the systematic error, an automatic calibration function, a more thorough performance analysis, and code optimizations using multiple threads.

Abstract:
This project simulates QPSK modulation signals and uses a laboratory environment to create deteriorating effects of real-world high frequency (HF) transmissions that may modify the ideal QPSK waveform. These modifications may be identifiable in order to "fingerprint" the source of the modifications. To simulate the transmission path in the real world a signal generator is used to create the QPSK I/Q signal at the HF operating frequencies and a digital sampling oscilloscope acts as a receiver and records the data for analysis. A computer with MATLAB Instrument-control Toolbox is used to generate a random-input data stream as an input to the signal generator, which modulates the RF signal. The RF signal was chosen to be at HF (5-15 MHz) and the QPSK modulation was at 9600 baud. The deterioration effects of a real-world transmitter site were chosen to be associated with the output amplifier linearity and with the transmission line condition between the transmitter and antenna.

Abstract:
This thesis outlines the design and implementation of a single channel, dual polarization pulsar timing instrument for the Hartebeesthoek Radio Astronomy Observatory (HartRAO). The new timer is designed to be an improved, temporary replacement for the existing device which has been in operation for over 20 years. The existing device is no longer reliable and is di±cult to maintain. The new pulsar timer is designed to provide improved functional- ity, higher sampling speed, greater pulse resolution, more °exibility and easier maintenance over the existing device. The new device is also designed to keeping changes to the observation system to a minimum until a full de-dispersion timer can be implemented at theobservatory. The design makes use of an 8-bit Reduced Instruction Set Computer (RISC) micro-processor with external Random Access Memory (RAM). The instrument includes an IEEE-488 subsystem for interfacing the pulsar timer to the observation computer system. The microcontroller software is written in assembler code to ensure optimal loop execution speed and deterministic code execution for the system. The design path is discussed and problems encountered during the design process are highlighted. Final testing of the new instrument indicates an improvement in the sam- pling rate of 13.6 times and a significant reduction in 60Hz interference over the existing instrument.

Full text
Abstract:
Cette thèse de recherche-création s’appuie sur le travail de création mené par r∆∆dio c∆∆rgo , collectif de création radiophonique, autour de la notion de plateau-radio, en tant que dispositif de SF dans le sens que lui donne Donna Haraway, à savoir un espace de recherche-création dans lequel s’entremêlent Spéculation Féministe, Faits Scientifiques (Science Fact, Science-Fiction et jeu de ficelle (String Figure en anglais), c’est-à- dire une pratique collective qui produit autant un échange et une circulation de la pensée interdisciplinaire, qu’elle en cartographie son propre processus. La thèse tente de démontrer que le studio radiophonique tel qu’on le connaît aujourd’hui -avec ses micros, ses casques, ses animateur·ices qui reçoivent des invité·es et sa technicité qui canalise la parole et les sons au service d’une production adressée à des auditeur·ices - peut être appréhendé d’autres manières et à d’autres fins. La thèse se construit de manière polyphonique dans deux temporalités qui se superposent. Tout d’abord celle de comptes-rendus d’expériences artistiques réalisées entre 2017 et 2021, dans lesquels des collectifs vivent et expérimentent l’objet d’étude et dont l’écriture autorise une forme de style, celui d’un journal autoreflexif permettant de rendre compte des relations que les participant·es ont entre elles et eux et avec les dispositifs. En parallèle, une partie théorique, reposant elle sur une écriture scientifique, observera l’objet d’étude du plateau-radio avec le recul nécessaire pour produire une pensée théorique. Cette partie théorique propose une approche du plateau-radio en tant que dispositif de recherche-création artistique, scientifique et politique mais aussi en tant qu’espace relationnel de création aurale et émancipatrice. L’écriture polyphonique permet ainsi une friction entre spéculation artistique et écriture scientifique afin de faire émerger, dans l’entre-deux, une méthodologie de recherche-création. Une troisième voix apparaîtra donc peu à peu pour manifester une théorie-pratique à travers la méthodologie. Pour construire cette thèse il a ainsi été nécessaire de tresser au moins trois approches méthodologiques. La recherche débute par le concept de SF de Donna Haraway. Celui-ci découle des travaux d’Isabelle Stengers et Didier Debaise sur les gestes spéculatifs qui s’intéressent à comment la théorie peut-elle passer vers la pratique. Ce glissement de la théorie à la pratique par un arc à plusieurs cordes qu’offre le concept de SF se révèle nécessaire lorsqu’il n’y a pas encore assez de faits scientifiques pour poser une hypothèse et qu’il implique de passer par la pratique pour rendre manifeste un objet d’étude. Les deux autres approches sont mentionnées dans le plan résumé.Cette recherche débute donc avec la spéculation suivante :Et si,le plateau radio était un dispositif sorcier qui permet de tracer le cercle, dans le sens que lui donne Isabelle Stengers, à savoir un espace temporairement clos qui permet [aux sorcières éco-féministes] de récupérer les pouvoirs dont iels ont besoin ?
This creative research thesis is based on the creative work carried out by r∆∆dio c∆∆rgo, a collective of radio creation, around the notion of the radio platform, understood as a science fiction device in the sense given by Donna Haraway, that is, a space of research-creation where Feminist Speculation, Scientific Facts (Science Fact, Science Fiction), and String Figures intertwine. This approach constitutes a collective practice that produces not only an exchange and circulation of interdisciplinary thought but also maps its own process. The thesis aims to demonstrate that the radio studio as we know it today—with its microphones, headsets, hosts who invite guests, and its technical apparatus that channels speech and sounds for the purpose of production aimed at an audience—can be approached in other ways and for other purposes.The thesis is constructed in a polyphonic manner, unfolding in two overlapping temporalities. First, through reports on artistic experiments conducted between 2017 and 2021, in which collectives live and experiment with the object of study, and where the writing adopts a particular style—a self-reflexive journal that reflects on the relationships between the participants and with the devices. In parallel, a theoretical part, written in a scientific style, observes the object of study—the radio platform—with enough distance to produce theoretical thought. This theoretical section proposes an approach to the radio platform as a device for artistic, scientific, and political research-creation, but also as a relational space for aural and emancipatory creation. The polyphonic writing thus allows for friction between artistic speculation and scientific writing, to bring forth, in the in-between, a research-creation methodology. A third voice will gradually emerge to manifest a theory-practice through the methodology. In constructing this thesis, it was necessary to weave together at least three methodological approaches. The research begins with Donna Haraway’s concept of SF (science fiction/speculative fabulation), drawing from the work of Isabelle Stengers and Didier Debaise on speculative gestures, which examine how theory can move into practice. This shift from theory to practice, through the multi-string arc offered by the concept of SF, becomes necessary when there are not yet enough scientific facts to formulate a hypothesis, requiring practice to make the object of study manifest. The other two approaches are outlined in the summarized plan.Thus, this research begins with the following speculation:What if the radio platform was a witch’s device, enabling the drawing of the circle, in the sense given by Isabelle Stengers—namely, a temporarily enclosed space that allows [eco-feminist witches] to reclaim the powers they need ?

Abstract:
Low Density Parity Check (LDPC) codes are the parity check codes of long block length, whose parity check matrices have relatively few non-zero entries. To improve the performance at relatively short block lengths, LDPC codes are constructed by either pseudo-random or quasi-cyclic methods instead of random construction methods. In this thesis, pseudo-random code construction methods, the effects of closed loops and the graph connectivity on the performance of pseudo-random LDPC codes are investigated. Moreover, quasi-cyclic LDPC codes, which have encoding and storage advantages over pseudo-random LDPC codes, their construction methods and performances are reviewed. Finally, performance comparison between pseudo-random and quasi-cyclic LDPC codes is given for both regular and irregular cases.

Full text
Abstract:
In this work, a new multicast routing algorithm for wireless networks is presented. The algorithm, called SWIM (Source-initiated WIreless Multicast), is a depth-optimal multicast tree formation algorithm. SWIM is fully distributed and has an average computational complexity of O(N 2 ). SWIM forms a shared tree from the source(s) to destinations
yet, as a by-product, it creates a multicast mesh structure by maintaining alternative paths at every tree node. This makes SWIM suitable for both ad hoc networks and access networks with multiple gateways. An extension to the main algorithm is presented for the use in dynamic networks with mobility and/or dynamic destination group. Performance of SWIM is studied with simulations and is compared to other algorithms in the literature. Due to depth optimality, SWIM achieves a lower average and maximum delay than the compared algorithms. The throughput performance is found to be high. Working capability with rateless codes are also studied.

Abstract:
AbstractThis chapter discusses a ‘bottom-up’ approach to radio broadcasting drawing on the example of a women-only listening association formed in 2018, as a result of the research in this book, in the outskirts of Niamey, Niger’s capital. The chapter draws on concepts of empowering environments to demonstrate how, through collective solidarity or through power with, women have been able to create and develop their own listening associations. This has given members the opportunity, on the one hand, to meet, discuss, and cascade information, improving their lives and those of their families and communities, and, on the other hand, to set up microcredit facilities as part of these associations enabling them to create small businesses and use the income to the benefit of their families, even sending daughters to school and empowering the next generation. The chapter also shows how women, used to being under the domination of men, recognise their capacity to transform their daily lives by participating in community action. In doing so, shifts in women’s critical consciousness emerge in the chapter from perceiving themselves as secondary or incapable of effecting social change.

Abstract:
AbstractThe 1950s was a decade of wonderful flowering and exploration for the CSIRO Division of Radiophysics. From 1950, solar noise and cosmic noise scientists became “radio astronomers”. They were present as such in international astronomy as well as radio science meetings. The key achievements of the first 5 years of observing and categorising solar bursts and detecting and measuring discrete radio sources, had produced a set of challenging new research questions. Some were conceptual and theoretical—including, the nature of the unknown non-thermal radiation mechanism that underpinned cosmic radiation emission. Some concerned the complexities and challenges of instrumentation—the early 1950s saw swift innovation of instruments and methods, in order to resolve new research questions.

Abstract:
AbstractThis chapter is an account of the creativity of a host of engineers and scientists to build a groundbreaking radio telescope with the performance needed to extract the scientific treasures buried in weak radio signals from the distant Universe, of which there were previously only hints. Always moving forward, it describes the road from the ambition to overcome barriers and harness new technologies to the reality of thousands of difficult individual decisions that had to be made to successfully yield a realisable design in the available time. The global milieu in which this was done as an international project has set many precedents.

AbstractAs 1961 began, John Bolton re-joined CSIRO in early January. On 24 February 1961, a meeting of the 210-foot Radio Telescope Committee (aka the GRT) was held with Bowen (chair), Minnett (secretary), Pawsey, Beard, Higgs, Bolton, Cooper, Day, Mathewson, McCready and McGee. Pawsey had prepared a document 2 days earlier that set out a plan of action for the GRT; the construction was expected to be completed by August 1961. Pawsey described Phase 1 tests of the new aerial, consisting of determinations of the shape of the dish, pointing accuracy as a function of position, wind and temperature. An example was the determination of the “… directional patterns at various polarisations to access dish accuracy, the determination of the radio axis of the dish … The measurements will require a series of radio sources of known positions distributed over the coverage of the telescope.”

Abstract5G technology for mobile networking involves control communications to set up the radio channels and the authentication and security credentials. The control communications preceding the authentication and subscription verification remain vulnerable against the communication injection threats. We study the injection threats on control communications in 5G New Radio standard in 3GPP. From our 5G client-based implementation and experimentation against real-world networking, we analyze and measure the threat impact against the 5G service provider infrastructure of the core network. To secure 5G networking, our paper discusses about future research directions for increasing the understanding of such vulnerability/threat and for building greater security and availability for 5G networking against such wireless injection threats.

Full text
Abstract:
Radiofrequency spectrum is an essential asset for mobile network operators. Governments set its value to organize competitive frequency auctions and define recurrent payments, such as taxes and right of use. This publication sustains that governments should value radio frequency spectrum as a function of the intended frequency use policy and corresponding obligations. A mathematical formula is proposed to articulate, quantitatively, the relationship between spectrum value and regulatory obligations, including promoting new market entrants, conditioning of wholesale obligations, definition of coverage goals, and requirement to support public safety and first respondent services. This paper targets, in general, the telecommunication ministries, national regulatory authorities, and government entities that address the topic of valuing radio frequency spectrum.

Abstract:
Description Ballarat sits on Wathaurong land and is located at the crossroads of four main Victorian highways. A number of State agencies are located here to support and build entrepreneurial activity in the region. The Ballarat Technology Park, located some way out of the heart of the city at the Mount Helen campus of Federation University, is an attempt to expand and diversify the technology and innovation sector in the region. This university also has a high profile presence in the city occupying part of a historically endowed precinct in the city centre. Because of the wise preservation and maintenance of its heritage listed buildings by the local council, Ballarat has been used as the location for a significant set of feature films, documentaries and television series bringing work to local crews and suppliers. With numerous festivals playing to the cities strengths many creative embeddeds and performing artists take advantage of employment in facilities such as the Museum of Australian Democracy at Eureka. The city has its share of start-ups, as well as advertising, design and architectural firms. The city is noted for its museums, its many theatres and art galleries. All major national networks service the TV and radio sector here while community radio is strong and growing.

Full text
Abstract:
The SAE Regular Class Aero Design Competition requires students to design a radio-controlled aircraft with limits to the aircraft power consumption, take-off distance, and wingspan, while maximizing the amount of payload it can carry. As a result, the aircraft should be designed subject to these simultaneous and contradicting objectives: 1) minimize the aerodynamic drag force, 2) minimize the aerodynamic pitching moment, and 3) maximize the aerodynamic lift force. In this study, we optimized the geometric design variables of a biplane configuration using 3D aerodynamic analysis using the ANSYS Fluent. Coefficients of lift, drag, and pitching moment were determined from the completed 3D CFD simulations. Extracted coefficients were used in modeFRONTIER multi-objective optimization software to find a set of non-dominated (Pareto-optimal or best trade-off) optimized 3D aircraft shapes from which the winner was selected based to the desired plane performance.

Abstract:
The study analyzes the traditional media during 2013-2021 and draws attention to a number of factors, factors of economic and global nature in the historical context, which affect the general state of the media market in Ukraine. The main goal is to outline the peculiarities of the development of the print media market in modern conditions and challenges. The study uses socio-communicative and axiological approaches, methods of content analysis, synthesis and general are the main methods that were used in the research process. In addition to catalysts for abrupt changes in the print media market of Ukraine, factors have been identified that significantly affect the development trends of the general media market: digitalization, destruction of logistics, periodicals, outflow of advertisers from traditional media (television, radio, newspapers and magazines). There are already forecasts that due to the increase in the price of paper on the world market there will be an increase in prices for printed products by 40%), the lack of a culture of consumption of subscription information, as there is a free alternative (social networks, search engines). Results/findings and conclusions of my research: a set of three crisis periods, as a result of which the factors identified in the study are the main characteristics of the development of the modern print media market in Ukraine. The print media market, due to the global situation through COVID-19, is going through difficult times. In fact, the prospect for further scientific research may be the study of the financial component of the Ukrainian media market in the context of general world trends.

Villemot, Sébastien, and Daniel Cohen. Self-Fulfilling Debt Crises in Theory and Practice. Inter-American Development Bank, December 2006. http://dx.doi.org/10.18235/0010972.

Full text
Abstract:
This paper analyzes econometrically how a country's post-crisis debt ratio could be forecast, in the aftermath of a debt crisis, from the previous debt-to-GDP ratio. A critical parameter is simply the debt-to-PPP-GDP ratio, where PPP-GDP is, in current international dollars, the Summers-Heston value. In this formulation, this paper shows that the Latin American paradox disappears. This then leads to a simple conclusion: debt crises are more frequent in Latin American countries because they have more damaging consequences on the market value of GDP. This itself appears to be closely related to the fact that pre-crisis Latin American exchange rates are also overvalued (for a similar emphasis, see Calvo et al., 2003). As a simple consequence of this model, the paper suggests computing the debt-to-PPP-GDP ratio as a new standard for analyzing debt sustainability.

Bruce. L52090 Near-Neutral pH SCC - Dormancy and Re-Initiation of Stress Corrosion Cracks. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), April 2003. http://dx.doi.org/10.55274/r0011360.

Full text
Abstract:
The objective of this research project was to identify the environmental, metallurgical, and mechanical conditions that lead to dormancy and re-initiation of previously dormant stress corrosion cracks. These parameters would assist pipeline operators in mitigating near-neutral pH SCC on their systems, and allocating resources for pipeline maintenance. Unload-reload transients were found to increase the crack growth rate in the majority of the experiments and to re-initiate dormant stress corrosion cracks in several cases. On the other hand, there was no consistent effect of the presence or magnitude of overloads on crack growth behavior. The simulated hydrostatic tests had relatively little effect on the crack velocities for near dormant conditions, but consistently inhibited subsequent crack growth for actively growing cracks. The results of analyses of the data and modeling suggest that the R ratio (ratio of minimum to maximum pressure) and frequency of pressure fluctuations on an operating pipeline can be used as a tool to rank segments of pipelines base on the mechanical driving force for propagation of near neutral pH SCC. The concept of a critical crack tip strain rate, which can be related to the R ratio and frequency, also can be used to reasonably predict whether a given set of loading conditions will lead to dormancy.

Kanninen. PR-380-104500-R01 Minimum Permissible Bend Radii for Layered Composite Materials. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), March 2013. http://dx.doi.org/10.55274/r0010802.

Full text
Abstract:
The research utilized a closely coordinated combination of full-scale bend/burst testing and highly detailed finite element analysis (FEA) modeling of representative HPIR constructions in a two-phase iterative approach. The fundamentally sound methodology that was developed and validated in the research has the potential for optimizing the design of HPIR systems in regard to safely negotiating tight bends while renewing energy transmission pipelines in a wide range of operating conditions. The combination of FEA modeling and the full-scale bend/burst testing utilized in this research has led to an important conclusion in regard to the burst strengths of HPIR designs . In a 10D radius of curvature (RoC) bend (i.e., a multiple of 10 times the nominal diameter of the host pipe), the burst strength of an HPIR design is only 5% less than its burst strength in a straight segment. In addition, the analyses have strongly indicated that much tighter bends can also be accommodated without encountering drastic burst strength reductions. It has also become clear from this work that the further research needed to establish a full set of minimum allowable RoC values for HPIR installations must be based upon the stresses arising from the combination of RoC, bend angle, diametrical clearance, and axial tension. . A preliminary application of the methodology for an HPIR installation in a cased crossing rehabilitation is included in this report to demonstrate that this new technology has already been implemented and that it has made a significant impact in a commercial installation. Recommended further research that would generalize and substantiate a broad-based methodology for determining the minimum permissible RoC of a pipeline bend that can be negotiated in an installation of the HPIR system beyond the 10D value established in this research is also outlined in the report.

Abstract:
Nu har det redan gått två år sen vi sjösatte referensområdet ’Ljusdal’. Vi ser att årets observationer förstärker bilden vad vi såg året innan i området, samt vissa observationer liknar vad vi ser i andra studieområden, medan andra skiljer sig åt. Studieområdet i Ljusdal är speciellt i två avseenden som berör älgar direkt och därmed skiljer sig åt från andra studieområden: brandfältet och en hög täthet av brunbjörn. Som förväntat ser vi skillnader mellan olika älgindivider och resultaten liknar vad vi sett i andra delar av landet - en del älgar har helt skilda sommar- och vinterområden, andra har områden som överlappar delvis, och ett fåtal verkar ha i stort sett helt överlappande områden. Av de 39 älgar vi kunde följa under mars 2021-2022, var drygt hälften stationära där några älgar har förflyttat sig bara en kort sträcka mellan sitt vinter- och sommarområde. Den andra halvan hade klart avskilda säsongsområden där merparten höll sig inom 20-25 km radie till sitt vinterområde. Men vi kunde också följa några riktiga långvandrare! Tjugofem av de 39 GPS-märkta älgarna kunde vi lokalisera i brandfältet under året. Hur länge älgarna uppehöll sig inom brandområdet varierade mellan individerna. Stationära älgkor återfanns fler dagar inom området jämfört med vandringskorna. Älgarna nyttjade brandfältet framförallt under vegetationsperioden (maj-okt/nov) där några rörde sig inom brandområdet medan många älgar främst rörde sig i ytterkanterna. Alla kor, förutom F1874, F1887 och F1924, kalvade och vid hälften av kalvningarna föddes tvillingkalvar. Medelkalvningsdagen var 18:e maj. Sommaröverlevnaden av de årskalvar som föddes under kalvningssäsongen 2021 var mellan 17 och 26% fram till jaktstarten och låg därmed högre än året innan då överlevnad låg mellan 13-17 %. Sommeröverlevnaden är betydligt lägre jämfört med områden utan större rovdjur. I studieområdet i Ljusdal utsätts årskalvar för predation framförallt av björn. För en tredjedel av kalvarna som försvann under sommaren kunde vi verifiera björnpredation genom fynd i fält och för ytterligare en tredje del misstänker vi predation. Vid vinterkoll efter jakten var överlevnaden 12%. Insamlingen av prover under jakten resulterade i ca 70 käkar och 20 kompletta reproduktionsorgan från hondjuren. Medelåldern hos de bedömda fällda hondjuren var 8.4 år och hos tjurar 4.4 år, och de respektive slaktvikterna låg på ca 188.0 och 201.0 kg. Slaktvikten för kalv låg i snitt på 71.5 kg. Fetthalten i benmärgen var i medel 81% för kor, 70% för tjurar och 74% för kalvar. En viktig orsak till att försökspopulationen i Ljusdal fungerar så bra är det nära samarbetet med alla intresserade.

Abstract:
Wolbachia are intracellular bacteria known to cause reproductive and sex ratio disorders in many insects. In various parasitic Hymenoptera, Wolbachia induce thelytokous reproduction. The overall goal of this research was the improvement of biological control agents by reversion of their mode of reproduction. This was attempted from two directions: 1) studying the effect of naturally occurring Wolbachia on the thelytokous species Muscidifuraxuniraptor and 2) trying to transmit thelytoky-inducing Wolbachia to Nasoniavitripennis. In M. uniraptor, gamete duplication was found to be the mode of diploidy restoration and Wolbachia density had a strong effect on sex ratio but not on host fitness. Studies on the natural horizontal transmission of Wolbachia between Nasonia wasps and their Protocalliphora hosts using the Wolbachia Outer Surface Protein (WOSP) gene revealed that (a) two Nasonia species (N. giraulti and N. longicornis) possess closely related strains of B-group Wolbachia, but N. vitripennisapparently acquired B Wolbachia by horizontal transmission from an unknown source, (b) Nasonia and its Protocalliphora host have similar Wolbachia, and (c) the Protocalliphora Wolbachia WOSP gene is a recombinant between the one found in N. giraulti/longicornis and N. vitripennis. Results show parasitoid-host insect transmission of Wolbachia and recombination among Wolbachia strains. Results from gynandromorph studies suggest a novel mechanism of sex determination in Nasonia.
