Planet formation by pebble accretion in ringed disks
Creators: name: Morbidelli, Alessandro
Publisher: name: arXiv

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Context: Pebble accretion is expected to be the dominant process for the formation of massive solid planets, such as the cores of giant planets and super-Earths. So, far, this process has been studied under the assumption that dust coagulates and drifts throughout the full protoplanetary disk. However, observations show that many disks are structured in rings that may be due to pressure maxima, preventing the global radial drift of the dust. Aims: We study how the pebble-accretion paradigm changes if the dust is confined in a ring. Results: Planet Type-I migration is stopped in a ring, but not necessarily at its center. If the entropy-driven corotation torque is desaturated, the planet is located in a region with a low density of dust, which severely limits its accretion rate. If instead the planet is near the ring's center, its accretion rate can be similar to the one it would have in a classic (ring-less) disk of equivalent dust density. However, the growth rate of the planet is limited by the diffusion of dust in the ring and the final planet's mass is bounded by the total ring's mass. The DSHARP rings are too far from the star to allow the formation of massive planets within the disk's lifetime. However, a similar ring rescaled to 5 AU could lead to the formation of a planet incorporating the full ring's mass in less than 1/2 My. Conclusions: The existence of rings may not be an obstacle to planet formation by pebble-accretion. However, for accretion to be effective the resting position of the planet has to be relatively near the ring's center and the ring needs to be not too far from the central star. The formation of planets in rings can explain the existence of giant planets with core masses smaller than the so-called pebble isolation mass.

description: The following thesis surveys artistic utilizations of the archive and underscores its role as a tool for knowledge disruption. Fluctuating between theoretical meanderings, autobiographical reflections, and the analysis of artwork, I propose one avenue in which to reinvigorate conversations around the archive began by Derrida in Archive Fever and by Hal Foster in “Archival Impulse.” Approaching the archive as both a theoretical container and as a charged artist medium, I argue for a new archival impulse — one that embraces opaqueness and mess over clarity and order. Comprised of eight individual sections, and a parallel dialogue presented in the form of extended footnotes, the thesis borrows formal and stylistic strategies from arenas of creative non-fiction, diaristic writing, and art historical analysis. Archive scholars — Derrida, Foster, Michel Foucault, Annet Dekker — are cross-examined with thinkers in fields of queer theory, ecology, art history, philosophy, media studies, performance studies, and cultural studies — José Muñoz, Lee Edelman, Sara Ahmed, Jane Bennett, Hito Steyerl, Graham Harman, Timothy Morton, Nicholas de Villiers. Contextualizing artwork made during my time in graduate school through contemporary artists working in the fields of painting, performance and installation, I outline how this research has led me to define a particularly artistic subcategory of archival discourse capable of capturing the pulse of an American undercurrent. Artists building with and through the counter-archive look backward to engage with the potentiality of what has not yet come to pass. Their unorthodox strategies for collecting and sharing history employ the archive not as merely a bank of historical knowledge, but in fact, as a formally antagonistic counter to the ways in which history and other forms of knowledge production are weaponized as systems of oppression.

description: We report the results of a study of the Hall effect and magnetoresistance in single crystals of Sr2RuO4 in which Sr^(2+) has been substituted by La^(3+) (Sr(2-y)La(y)RuO(4)) or Ru^(4+) by Ti^(4+) (Sr(2)Ru(1-x)Ti(x)O(4)). For undoped Sr2RuO4, the purity is so high that the strong-field Hall coefficient can be measured for fields above 4 T. The conventional weak-field Hall coefficient as a function of doping shows a sharp jump and sign change at y ~ 0.01 that is unrelated to either a sharp change in Fermi-surface topography or a magnetic instability. The implications of these results are discussed.

description: We study a class of heat engines including Feynman's ratchet, which exhibits a directed motion of a particle in nonequilibrium steady states maintained by two heat baths. We measure heat transfer from each heat bath separately, and average them using a careful procedure that reveals the nature of the heat transfer associated with directed steps of the particle. Remarkably we find that steps are associated with nonvanishing heat transfer even in equilibrium, and there is a quantitative relation between this ``hidden heat transfer'' and the directed motion of the particle. This relation is clearly understood in terms of the ``principle of heat transfer enhancement'', which is expected to apply to a large class of highly nonequilibrium systems.

description: Multilevel artificial cervical disc replacement and anterior hybrid surgery have been established as effective treatments for multilevel cervical degenerative disc disease. Proper surgical techniques are essential to alleviate patient symptoms and ensure the optimal functioning of cervical implants. However, the use of incorrect surgical strategies may result in complications such as implant migration and neurological deficits. In this paper, we outline our surgical strategies for multilevel cervical disc replacement and hybrid surgery, summarized into five key points.

description: We consider the harmonic superspace formulation of higher-derivative $6D$, ${\cal N}=(1,0)$ supersymmetric gauge theory and its minimal coupling to a hypermultiplet. In components, the kinetic term for the gauge field in such a theory involves four space-time derivatives.The theory is quantized in the framework of the superfield background method ensuring manifest $6D$, ${\cal N}=(1,0)$ supersymmetry and the classical gauge invariance of the quantum effective action. We evaluate the superficial degree of divergence and prove it to be independent of the number of loops. Using the regularization by dimensional reduction, we find possible counterterms and show that they can be removed by the coupling constant renormalization for any number of loops, while the divergences in the hypermultiplet sector are absent at all. Assuming that the deviation of the gauge-fixing term from that in the Feynman gauge is small, we explicitly calculate the divergent part of the one-loop effective action in the lowest order in this deviation. In the approximation considered, the result is independent of the gauge-fixing parameter and agrees with the earlier calculation for the theory without a hypermultiplet.

description: The perception of markets delivering a Pareto optimal solution with distribution of benefits and value creation along the supply chain has been evolving from a theoretical perspective and respective assumptions toward more pragmatic and sophisticated analysis. Food and agricultural production, at farm level, frequently faces great challenges and deviations from theory optimal solutions, mainly when markets do not have the necessary conditions for “perfect functioning”. Institutional innovation and regulations from the supply side and from the demand side have been able to offer solutions, some of them science based. Those examples deserve attention and can offer sound base for improvements in our knowledge about market behaviour and development for improved dynamics and innovation in the food systems. The analysis will be centred in case studies in Europe, Africa and Latin America, providing examples where science has been playing an important role for good market performances. In the wine sector in Europe, regulations started very early, and were based on market needs and value creation strategies. Food aid for development purposes also evolved during the last decades, from tangible goods distribution toward other forms of cooperation for development, which has been very important for African countries. Last but not least, we would like to address the examples of private sector organizations with market regulatory interventions, such as the sugar cane sector with a scientific based support from research team’s efforts (like CEPEA at the University of S. Paulo/Brazil, among others).
Solution of a Model for the Oceanic Pycnocline Depth: Scaling of Overturning Strength and Meridional Pressure Difference

description: We present an analysis of the model by Gnanadesikan [1999] for the pycnocline depth in the ocean. An analytic solution for the overturning strength as a function of the meridional pressure difference is derived and used to discuss their mutual scaling. We show that scaling occurs only in two unphysical regimes of the model. In the absence of the Southern Ocean (SO) processes, i.e. for a northern overturning cell, the volume transport is proportional to the square root of the pressure difference. Linear scaling is seen when the overturning is restricted entirely to the SO, i.e. when no northern downwelling exists. For comparison, we present simulations with the coupled climate model CLIMBER-3$α$ which show linear scaling over a large regime of pressure differences in the North Atlantic (NA). We conclude that the pycnocline model is not able to reproduce the linear scaling between its two central variables, pressure and volume transport.

description: Gaseous detectors are used in high energy physics as trackers or, more generally, as devices for the measurement of the particle position. For this reason, they must provide high spatial resolution and they have to be able to operate in regions of intense radiation, i.e. around the interaction point of collider machines. Among these, Micro Pattern Gaseous Detectors (MPGD) are the latest frontier and allow to overcome many limitations of the pre-existing detectors, such as the radiation tolerance and the rate capability. The gas Electron Multiplier (GEM) is a MPGD that exploits an intense electric field in a reduced amplification region in order to prevent discharges. Several amplification stages, like in a triple-GEM, allow to increase the detector gain and to reduce the discharge probability. Reconstruction techniques such as charge centroid (CC) and micro-Time Projection Chamber ($\upmu$TPC) are used to perform the position measurement. From literature triple-GEMs show a stable behaviour up to $10^8\,$Hz/cm$^2$. A testbeam with four planar triple-GEMs has been performed at the Mainz Microtron (MAMI) facility and their performance was evaluated in different beam conditions. In this article a focus on the time performance for the $\upmu$TPC clusterization is given and a new measurement of the triple-GEM limits at high rate will be presented.

description: A new algorithm for solving the general relativistic MHD equations is described in this paper. We design our scheme to incorporate black hole excision with smooth boundaries, and to simplify solving the combined Einstein and MHD equations with AMR. The fluid equations are solved using a finite difference Convex ENO method. Excision is implemented using overlapping grids. Elliptic and hyperbolic divergence cleaning techniques allow for maximum flexibility in choosing coordinate systems, and we compare both methods for a standard problem. Numerical results of standard test problems are presented in two-dimensional flat space using excision, overlapping grids, and elliptic and hyperbolic divergence cleaning.

Topological Charges, Prequarks and Presymmetry: a Topological Approach to Quark Fractional Charges
Creators: name: Matute, Ernesto A.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A topological approach to quark fractional charges, based on charge constraints unexplained by the Standard Model of particle physics, is discussed. Charge fractionalization is related to a tunneling process occurring in time between pure gauge field configurations at the far past and future associated with integer-charged bare quarks, named prequarks. This transition conforms to a topologically nontrivial configuration of the weak gauge fields in Euclidean space-time. In this context, an electroweak $Z_{2}$ symmetry between bare quarks and leptons, named presymmetry, is revealed. It is shown that an effective topological charge equal to the ratio between baryon number and the number of fermion generations may be associated with baryonic matter. The observed conservation of baryon number is then connected with the conservation of this charge on quarks. Similar results are obtained for leptons in the dual scenario with local quark charges.

description: We put recent results by Chen, Deng, Du, Stanley and Yan on crossings and nestings of matchings and set partitions in the larger context of the enumeration of fillings of Ferrers shape on which one imposes restrictions on their increasing and decreasing chains. While Chen et al. work with Robinson-Schensted-like insertion/deletion algorithms, we use the growth diagram construction of Fomin to obtain our results. We extend the results by Chen et al., which, in the language of fillings, are results about $0$-$1$-fillings, to arbitrary fillings. Finally, we point out that, very likely, these results are part of a bigger picture which also includes recent results of Jonsson on $0$-$1$-fillings of stack polyominoes, and of results of Backelin, West and Xin and of Bousquet-Mélou and Steingr\'ımsson on the enumeration of permutations and involutions with restricted patterns. In particular, we show that our growth diagram bijections do in fact provide alternative proofs of the results by Backelin, West and Xin and by Bousquet-Mélou and Steingr\'ımsson.

description: As part of ProSafeBeef, an integrated research project funded by the European Commission, the present qualitative study was carried out with European consumers to obtain insights into their acceptance or rejection of eight selected novel beef production and processing technologies, identified here as concepts: 1) marinating by injection for increased healthiness; 2) marinating by injection for increased safety; 3) marinating by injection for increased eating quality; 4) marinating by submerging for increased eating quality; 5) nutritional enhancement; 6) shock wave treatment; 7) muscle profiling and 8) thermal processing. In total, 65 adults between 19- 60 years of age participated in eight focus groups that were performed in Spain, France, Germany and the United Kingdom. In each country, two group discussions were performed; one composed of women and another one of men who lived in the respective capital cities: Madrid, Paris, Berlin and London. A common and translated topic guide was developed prior to the field work. A ranking exercise was applied, where the participants classified the technologies into accepted, neutral or rejected concepts, after discussing the perceived benefits and risks of each one of them. The obtained data was consecutively transcribed, coded and analysed by using the software package NVivo 7. The results reveal a dependency between the acceptance of novel beef products and how consumers perceive the characteristics of the innovation itself. Excess manipulation and a growing distance from a ‘natural’ way of processing beef products were considered to be very negative outcomes of technological innovations in beef processing. Apparently, novel technologies applied in beef production are predominantly seen as a valuable option for convenience shoppers and those who are less demanding in terms of beef quality and have less culinary skills. However, consumers support the development of technologies that can provide more healthiness and better eating quality, and if such technologies are ‘not invasive’, the chances to be accepted increase. Current trends and development in society, global warming crisis, disease outbreaks and degradation of the environment are shaping consumers’ opinion in regard to foodproduction. There was a severe criticism about too much intervention in food and a strong desire to keep food and beef processing as simple and natural as possible.

description: The Indo-Pacific Slender Gecko Hemiphyllodactylus typus is distributed across the Indian and Pacific Oceans. Its ecological flexibility andvast distribution may raise concerns of a potential invasion in tropical and subtropical islands worldwide, but evidence of a recent spread is lacking.The identity of the species has also been questioned across its distribution range. In this note we synthesise information obtained from the literature onthe distribution and the habitat use of the species. We stress the need to develop new sampling techniques to improve its detection, and performphylogenetic analyses to formally identify the species across the different regions and determine its colonisation history.

We discuss several properties of these definitions and explain some applications of this approach to questions regarding uniform convergence of metrics with scalar curvature bounded below. Finally, we consider the relationship between this approach and some other generalized notions of lower scalar curvature bounds.

description: An analysis of the candidate embedded stellar systems in the reflection nebulae vdBH-RN26, vdBH-RN38, vdBH-RN53a, GGD20, ESO95-RN18 and NGC6595 is presented. Optical spectroscopic data from CASLEO (Argentina) in conjunction with near infrared photometry from the 2MASS Point Source Catalogue were employed. The analysis is based on source surface density, colour-colour and colour-magnitude diagrams together with theoretical pre-main sequence isochrones. We take into account the field population affecting the analysis by carrying out a statistical subtraction. The fundamental parameters for the stellar systems were derived. The resulting ages are in the range 1-4 Myr and the objects are dominated by pre-main sequence stars. The observed masses locked in the clusters are less than 25 solar masses. The studied systems have no stars of spectral types earlier than B, indicating that star clusters do not necessarily evolve through an HII region phase. The relatively small locked mass combined with the fact that they are not numerous in catalogues suggests that these low mass clusters are not important donors of stars to the field populations.

description: Purpose: To assess agreement of Tear Film osmolarity (TFO) with other diagnostic tests for dry eyes in IndiansStudy Design: It is a retrospective chart review of consecutive case records of cases in a period of 4 months with at least one chief complaint that is a part of the OSDI scoring system of dry eye disease or came specifically for dry eye evaluation.Methods:All cases had been subjected to of Schirmer’s test, fluorescein tear film break-up time (FBUT) and non-invasive break-up time (NIBUT) on the Oculus Keratograph, OSDI scoring, and Fluorescein staining, and tear film osmolarity by the electrical impedance-based lab-on-a-chip technology (Tear Lab Osmolarity System). 42 case records in the study period formed a convenience series. 22 case records with data entry of all 6 tests were included in final analysisResults: Of the 22 patients, 86.3% were of South Asian Ethnicity, 3 belonged to the Somali Cushites residing in India, and 12 were female. Mean age was 42.9years (SD 12.8, range 23 to 73years),68.18% described themselves as Video display unit users. Cohens Kappa showed negative values for all observations including abnormal any 1 criterion indicative of disagreement worse than expected by chance. The Sensitivity and Specificity of TFO to detect DED was 28.00% (+/-18.76 CI) and 50% (+/-20.89) respectively. Youden’s index was negative (-.22).Conclusions:Our results suggest that currently accepted thresholds of TFO do not aid in DED diagnosis in Indians. But verdict on TFO role cannot be made, as environmental factors affect diagnostic thresholds. This is the only paper from the India describing tear film osmolarity in dry eye patients.

description: First we describe briefly an information-action method for the study of stochastic dynamics of hamiltonian systems perturbed by thermal noise and chaotic instability. It is shown that, for the ensemble of possible paths between two configuration points, the action principle acquires a statistical form $=0$. The main objective of this paper is to prove that, via this information-action description, some quantum like uncertainty relations such as $\geq\frac{1}{\sqrt{2}η}$ for action, $\geq\frac{1}η$ for position and momentum, and $\geq\frac{1}{\sqrt{2}η}$ for hamiltonian and time, can arise for stochastic dynamics of classical hamiltonian systems. A corresponding commutation relation can also be found. These relations describe, through action or its conjugate variables, the fluctuation of stochastic dynamics due to random perturbation characterized by the parameter $η$.

description: This paper addresses the various modes of access to production factors, such as capital, specific inputs and know-how, as reasons for the varied development of Romanian dairy supply chains and their respective actors (farmers, processors). The paper draws on results from an ongoing World Bank study. The findings are based on semi-structured telephone and face-to-face interviews conducted in January-February 2009. The interviews indicate that large and prosperous dairy chains have better access to all production factors, which allows the strengthening of their relationships, especially in the upstream stages (farmers), and supports their competitive advantages in the domestic market. Many barriers exist in the domestic market, particularly for small and medium-sized dairy chains, which hamper their potential exploitation of particular stages in the chain. In the same way the findings indicate that virtually only large companies and farms benefit from public support regarding access to capital (EU funding, governmental programmes) and know-how (extension service).

description: We conduct direct simulations of turbulent channels imposing different virtual origins for all three velocities using Robin, slip-like boundary conditions to study the effect of displacing the origins perceived by different flow components, a mechanism common to small-textured surfaces. We also explore this effect using opposition control. For riblets, Luchini et al. (1991) proposed that their effect could be reduced to the offset between the streamwise- and spanwise-velocity origins, the latter being the origin perceived by turbulence. Later results on superhydrophobic surfaces suggest that the apparent wall-normal-velocity origin could also play a role. Our results support that the relevant parameter is the offset between the origins perceived by the mean flow and by turbulence. The former is determined by the streamwise slip length, but the latter depends on both the wall-normal and spanwise slip lengths. The slip on the streamwise velocity fluctuations, in turn, has a negligible effect on the virtual origin for turbulence, at least in the drag-reduction regime. This suggests that the origin perceived by the quasi-streamwise vortices, which induce the cross velocities at the surface, is key in determining the virtual origin for turbulence, while that perceived by the near-wall streaks, which are associated with the streamwise velocity fluctuations, plays a secondary role. In this framework, the changes in turbulent quantities typically reported in the flow-control literature are shown to be only a result of the choice of origin and are absent when referenced to the origin experienced by turbulence. Other than this shift in origin, we show that turbulence remains essentially smooth-wall-like, and a simple expression can predict the virtual origin for turbulence. The effect on drag can be reproduced a priori by introducing the virtual origins into a smooth-wall eddy-viscosity framework.

description: We present a detailed study of vortex core spectroscopy in slightly overdoped Bi2Sr2CaCu2O8 using a low temperature scanning tunneling microscope. Inside the vortex core we observe a four-fold symmetric modulation of the local density of states with an energy-independent period of (4.3\pm 0.3)a0. Furthermore we demonstrate that this square modulation is related to the vortex core states which are located at ~6 meV. Since the core-state energy is proportional to the superconducting gap magnitude, our results strongly suggest the existence of a direct relation between the superconducting state and the local electronic modulations in the vortex core.

description: Using the coupled climate model CLIMBER-3a, we investigate changes in sea surface elevation due to a weakening of the thermohaline circulation (THC). In addition to a global sea level rise due to a warming of the deep sea, this leads to a regional dynamic sea level change which follows quasi-instantaneously any change in the ocean circulation. We show that the magnitude of this dynamic effect can locally reach up to ~1m, depending on the initial THC strength. In some regions the rate of change can be up to 20-25 mm/yr. The emerging patterns are discussed with respect to the oceanic circulation changes. Most prominent is a south-north gradient reflecting the changes in geostrophic surface currents. Our results suggest that an analysis of observed sea level change patterns could be useful for monitoring the THC strength.

description: The optical responses of structured array of noble-metal nanoparticle dimers immersed in a glass matrix are investigated theoretically, motivated by the recent experimental observation of the splitting of the surface plasmon bands in silver arrays. To capture the strong electromagnetic coupling between the two approaching particles in a silver dimer, the spectral representation of the multiple image formula has been used, and a semiclassical description of the silver dielectric function is adopted from the literature. The splitting of plasmon resonance band of the incident longitudinal and transverse polarized light is found to be strongly dependent on the particle diameter and their separation. Our results are shown in accord with the recent experimental observation. Moreover, a large redshift for the longitudinal polarization can be reproduced. The reflectivity spectrum is further calculated for a dilute suspension of dimer arrays.

The Gleno Dam Disaster (1923). Cultural Trauma and Collective Memories of an In-Depth Mountain Community in Italy a Century Later
Creators: name: Migliorati, Lorenzo
Publisher: name: Italian Sociological Review
Year: 2024

description: There is the wreckage of a broken Dam in Val di Scalve, a remote valley in the Italian Alps. At 7:15 am on December 1, 1923, the Gleno Dam collapsed and the flood wave swept over the villages below, all the way to Lake Iseo and the plain, killing about 356 people (out of a population of about ten thousand people). Our research takes stock of the social vulnerability of the affected communities, one hundred years later, and aims to interpret this disaster in the broader framework of the irruption of industrial modernity in the Alps and its consequences. What did modernity mean in the most peripheral areas of the Alpine mountains? What conditions of vulnerability did it generate? And, under what conditions can the social memory of the past heal the wounds of communities affected by disasters? And under what conditions can it further aggravate the sense of trauma suffered? The research was conducted using hermeneutic methods and qualitative techniques to investigate the processes of collective memory construction, with specific reference to social vulnerability and cultural trauma, among the communities affected by the Gleno disaster. What emerges is a picture of an Alpine community in which the representation of the pain of one’s past still constitutes a major activator of social phenomena and ferments one hundred years later.

description: In recent years the Hungarian milk sector has had serious problems. Since the EU accession, domestic milk production has continuously declined, the balance of the foreign trade of milk and dairy products has deteriorated year after year and the degree of self-sufficiency has fallen below 100%. This paper, drawing on the study of Popp and Potori [2009], analyses why the competitive position of the Hungarian milk and dairy sector has collapsed in recent years.
Iconic Brands’ Sustainability, Socioeconomic Contexts and the Nigerian Experience

description: Over the past two decades, iconic brands have garnered considerable attention due to their status as ideal brands. Although several studies have addressed cultural branding as a management tool for iconic brands, relatively limited literature has empirically examined iconic brands in socioeconomic contexts. As far as Nigeria is concerned, little research is related to the previous discourse. Consequently, the study investigated the socioeconomic contexts influencing iconic brands in Nigeria. The methodology involved using inductive thematic analysis to investigate selected companies’ annual reports and interview transcripts from top management officials. The sampling techniques were purposive with a theoretical undertone. The study identified the following socioeconomic contexts- insecurity, poor infrastructure, volatility of the economy, resilience, value co-creation, and communicative anchor of brand management. In addition, this study explored selected iconic corporate brands in the Nigerian environment, thereby enhancing the ongoing dialogue on product and service branding in other national contexts.

description: The EU Framework 7 project “RuralJobs” has used the DPSIR model to show the link between ‘driving forces’ of employment and economic prosperity, and policy responses. These driving forces can be ‘endogenous’ or (neo-) ‘exogenous’ to the territory. They act on the labour market or employment (‘state’) through the ‘pressures’ of jobs (economic activities) and people (the labour force). In turn, the employment rate (jobs per person) influences the ‘impact’ (sustainable economic prosperity). ‘Responses’ can be policy responses or socio-economic responses. A set of 40 indicators was compiled from strategies and programmes relevant to employment in rural areas in the EU.

description: We report here differential cross sections for the reaction $γp \to K^{*0}Σ^+$ for the first time with high statistics. The measurements were done using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Data were taken at 3.115 GeV electron beam energy using tagged photons incident upon a liquid hydrogen target. In addition, our analysis provides information about nucleon resonances and their couplings to $K^*$ decay. Our data will be used to test predictions of theoretical models of K$^*$ production, and to provide constraints on the $K^*ΣN$ coupling constant used in these models.

IMAGING OF SPONDYLODISCITIS: AN UPDATED COMPREHENSIVE REVIEW—MULTIMODAL IMAGING FEATURES, DIFFERENTIAL DIAGNOSIS, AND DETECTION OF SPECIFIC MICROORGANISMS
Creators: name: Sattorov, Bekhruz
Publisher: name: Zenodo
Year: 2024

description: Spondylodiscitis refers to infectious conditions affecting the vertebral column, and its incidence has steadily increased in recent decades. Imaging plays a crucial role at every stage of the disease. Radiological techniques are essential for (i) the initial diagnosis of spondylodiscitis, (ii) distinguishing it from other causes such as inflammatory, degenerative, or calcific disorders, (iii) assessing disease progression, and (iv) providing indications of the microorganisms involved. The latter can be achieved either through minimally invasive procedures (e.g., CT-guided biopsy) or inferred non-invasively by analyzing the features presented in CT, positron emission tomography (PET) CT, or MRI scans. This comprehensive review aims to outline the multimodal imaging characteristics of spondylodiscitis, serving as a reference for physicians, including infectious disease specialists, spine surgeons, and radiologists. Additionally, this review may offer insights for future research articles.

description: There are an increasing number of references in the literature on the significance of the role of farm households and farm families in the development of multifunctional agriculture. The motivation and intentions of 104 farmers in three LEADER micro-regions in Northern and Eastern Hungary with respect to the present and future structures of their farms (including the expansion of non-agricultural activities and functions) were investigated using questionnaires and narrative interviews. Almost two-thirds of the respondents spoke of the existence of non-agricultural activities and functions, but few of these were market-driven. The farmers ranked the steps that should be taken to increase multifunctionality in their own micro-regions in order of importance and indicated which organisations they thought would be most competent for their implementation. They also noted what factors promoted or inhibited multifunctionality within their own farms.
