Peu d'études se sont intéressées à la qualité de la fonction sexuelle masculine après traitement chirurgical de la fracture de la verge. L'objectif de notre travail est d'évaluer la fonction sexuelle masculine après traitement chirurgical de la fracture de la verge et l'étude des facteurs prédictifs de la dysfonction érectile postopératoire. Il s'agit d'une étude transversale, rétrospective incluant 28 patients opérés en urgence pour une fracture de la verge au sein de notre service sur une période de 6 ans. Afin d'évaluer l'impact du traitement chirurgical sur la fonction sexuelle, on a utilisé la version arabe du questionnaire IIEF-15 (International Index of Erectile Function-15) et le score EHGS (Erection Hardness Grading Scale). L'âge moyen des patients était de 42,6 ans. Le mécanisme le plus souvent retrouvé était le faux pas du coït. La dysfonction érectile était présente chez 9 patients dont un était en dysfonction érectile sévère. On a objectivé une différence statistiquement significative entre les scores pré- et postopératoire de l'IIEF-15 et de l'EHGS. Après une étude multivariée, aucun facteur indépendant n'a été incriminé dans la survenue de dysfonction érectile après chirurgie de la fracture de la verge. La fracture de la verge a un impact sur la fonction sexuelle. La pierre angulaire de la prise en charge est une réparation chirurgicale dans les plus brefs délais. Une réassurance et si besoin, un accompagnement psychologique après le traumatisme apparaissent nécessaires pour reprendre une activité sexuelle satisfaisante. Few studies have focused on the quality of male sexual function after immediate surgical treatment of the penile fracture. The aim of this study was to evaluate the male sexual function and more specifically the erectile function after surgical treatment of the penile fracture and to study the predictive factors of postoperative erectile dysfunction. This is a cross-sectional, single-center, retrospective, study including 28 patients operated on for a penile fracture in our urology department over a period of 6 years. In order to evaluate the impact of surgical treatment on sexual function, the Arabic version of the IIEF-15 (International Index of Erectile Function-15) questionnaire and the EHGS (Erection Hardness Grading Scale) score were used. The mean age of patients was 42.6 years. The most common mechanism found was misstep of coitus. Erectile dysfunction was noticed in 9 patients with a severe form in one case. There was a statistically significant difference between pre- and post-operative IIEF-15 and EHGS scores. After multivariate study, there was no independent factor of erectile dysfunction after penile fracture surgery. Penile fracture has an impact on male sexual function, particularly, erectile one. This condition should be managed rapidly with psychological assistance. [ABSTRACT FROM AUTHOR]

The investigation of sex bias and pseudohermaphroditism is a relatively unexplored area of research in the Neostromboidae. Here, we inform on these phenomena in a population of Gibberulus dekkersi Maxwell, Hernandez Duran, Rowell & Rymer, 2021 on Green Island, Great Barrier Reef. We collected 598 individuals, and noted the size of the cluster in which it occurred. Each individual was placed ventral side up and the body of the animal observed at the time of righting. Sex was determined by the presence or absence of a verge. During this sexing process, females were inspected for the presence of external male sexual organs to indicate the presence or absence of pseudohermaphroditism. We found that, overall, the population was not sexually biased towards one sex. However, we did find that individual clusters within the population showed significant sex bias, with different clusters favouring either males or females. Smaller clusters had a structural sex-ratio bias in favour of females. No evidence for pseudohermaphroditism was recorded, which indicates that the marine pollutant tributyltin (TBT) may not be present or at harmful levels in the surrounding environment. This study adds information from an unstudied Queensland taxon to the growing evidence on sex bias, clustering effects and pseudohermaphroditism within the Neostromboidae. [ABSTRACT FROM AUTHOR]

Due to the intensified land use in transformed landscapes, grassland biodiversity is often restricted to habitat fragments inadequate for arable use or for urban development. In continental parts of Eurasia, the ~600,000 ancient burial mounds (called “kurgans”) built by nomadic tribes of the steppes are amongst the most widespread landmarks providing refuge for dry grassland species. In our study by using plant functional groups and functional traits, we aimed at gaining insight into the ecological and evolutionary processes shaping the structure and the composition of assemblages of grassland specialist plant species on kurgans embedded in the agricultural landscapes of East-Hungary. As a comparison, we also studied roadside verges and pristine extensive grasslands in the same region. We found that despite their small size, due to the lack of human disturbances and high microhabitat diversity kurgans can maintain a high species richness and percentage cover of specialists, especially when compared to verges. We revealed that assemblages of specialist plants on kurgans are characterized by traits typical to terrestrial habitat islands such as self-compatibility, large seed mass and tall stature. Kurgans and extensive grasslands were characterized by higher functional diversity (both at the level of single traits and multi-trait based functional dispersion) which is probably due to the higher level of environmental heterogeneity compared to the homogeneous environment in verges.

In intensively used landscapes biodiversity is often restricted to fragmented habitats. Exploring the biodiversity potential of habitat fragments is essential in order to reveal their complementary role in maintaining landscape-scale biodiversity. We investigated the conservation potential of dry grassland fragments in the Great Hungarian Plain, i.e. patch-like habitats on ancient burial mounds and linear-shaped habitats in verges, and compared them to continuous grasslands. We focused on plant taxonomic diversity, species richness of specialists, generalists and weeds, and the phylogenetic diversity conserved in the habitats. Verges meshing the landscape are characterised by a small core area and high level of disturbance. Their species pool was more similar to grasslands than mounds due to the lack of dispersal limitations. They held high species richness of weeds and generalists and only few specialists. Verges preserved only a small proportion of the evolutionary history of specialists, which were evenly distributed between the clades. Isolated mounds are characterised by a small area, a high level of environmental heterogeneity, and a low level of disturbance. Steep slopes of species accumulation curves suggest that high environmental heterogeneity likely contributes to the high species richness of specialists on mounds. Mounds preserved the same amount of phylogenetic diversity represented by the branch-lengths as grasslands. Abundance-weighted evolutionary distinctiveness of specialists was more clustered in these habitats due to the special habitat conditions. For the protection of specialists in transformed landscapes it is essential to focus efforts on preserving both patch-like and linear grassland fragments containing additional components of biodiversity.

L'épispadias est une malformation urogénitale rare se caractérisant par une aplasie plus ou moins complète de la face supérieure de l'urètre. Fréquemment associé à une exstrophie vésicale, il est isolé dans 10% des cas. On distingue donc des épispadias continents et incontinents. Nous rapportons le cas d'un patient âgé de 29 ans, qui consulte pour prise en charge d'une dysurie et de l'mpossibilité d'avoir des rapports sexuels. À l'examen, des organes génitaux externes notaient une ouverture anormale de l'urètre sous forme de fente sur la moitié distale de la face dorsale de la verge. La verge ne présentait pas de courbure dorsale (chordée), les corps caverneux étaient palpés, légèrement latéralisés. La paroi abdominale était sans anomalie. Le reste de l'examen était normal. Devant cette anomalie, le diagnostic d'épispadias continent balano-pubien a été retenu. Une échographie de l'arbre urinaire réalisée est revenue normale et une radiographie sans préparation du bassin montrait un diastasis inter pubien. Le patient a été opéré en un temps selon la technique de Cantwell-Young, l'évolution postopératoire immédiate était sans anomalie; la sonde urétrale a été enlevée 21 jours plutard après cicatrisation. Le résultat fonctionnel et esthétique évalué à trois et à six mois ont été jugés satisfaisants sans brièveté de la verge.

But: présenter les aspects anatomocliniques, étiologiques et prendre en charge les amputations de verge dans le service d’urologie. Observations: il s’agissait de trois observations cliniques. Les patients étaient âgés de 25 ans, 18 ans et 30 ans. Le motif de consultation était l’amputation totale de la verge. Le délai de consultation était de 2 heures (n = 2) et 24 heures (n = 1). L’étiologie était criminelle (n = 2) et psychogène (n = 1). L’extrémité distale de la verge amputée était emportée par les bourreaux ou dissimulée par le patient. La prise en charge consistait en: un parage, la confection d’un méat urétral, la pose d’une sonde urétrovésicale. Un accompagnement par psychothérapie était nécessaire. Conclusion: qu’elle soit d’origine criminelle ou psychogène, l’amputation totale du pénis est rarissime. Les conséquences sont urinaires, sexuelles et psychogènes. La prise en charge doit être multidisciplinaire.

In India, there is a scheme to compute each day consumption of petroleum products but there is no scheme to measure each day consumption of LPG in household item for consumption. In the existing system, LPG providers were unable to predict the daily LPG usage of their customers and customers can only able to predict the emptiness of LPG cylinder at verge of inflammable burner. Nowadays the cost of LPG is increasing day by day. The LPG consumer has to dial a toll free number in order to register a booking service, there is a high chance to forget booking for next cycle[5]. The aim of this project is to develop an application (LPG-ON-TIP). The proposed system helps consumer aware of daily, weekly and monthly consumption of gas, thereby each consumer can increase number of days of usage. Proposed system helps to check quantity of LPG while refill and also verify it whether the LPG provider has delivered according to prescribed quantity. On verge of emptiness, proposed system activates automatic booking (without human intervention).Proposed system involves a feature of leakage detection and provide alert. Also consumer pay amount through online. [ABSTRACT FROM AUTHOR]

Les kératoses séborrhéiques (KS) sont des tumeurs épithéliales bénignes fréquentes. Elles se développent préférentiellement dans les zones séborrhéiques,notamment le visage et le tronc, rarement au niveau génital.Nous rapportons le cas d'un patient âgé de 41 ans, sans antécédents pathologiques notables, consultait pour des lésions pubiennes évoluant depuis trois ans. L'examen clinique retrouvait des lésions noirâtres à surface kératosique, cérébriformes au niveau de la verge. La biopsie cutanée était en faveur d'une kératose séborrhéique. Un traitement par électrocoagulation-curetage a été réalisé.Il existe deux théories expliquant le mécanisme de formation des KS. La première, émet l'hypothèse que les KS sont la résultante d'une prolifération de kératinocytes aboutissant à une inhibition de l'apoptose et l'expression de la survivine. D'après la seconde, les KS seraient le résultat d'une accumulation de kératinocytes sénescents avec une surexpression de la protéine p16. Dans le cas des KS génitales, le rôle du frottement chronique et de l'HPV a été suspecté. Le traitement repose sur l'exérèse chirurgicale, le curetage, la cryothérapie par azote liquide, l'application d'acide trichloroacétique, l'électrosection ou l'ablation par laser CO2. Si les KS ne posent pas a prioride problèmes de santé majeurs, leur localisation au niveau de la région génitale peut influencer négativement la vie sexuelle du patient, d'où l'intérêt d'une prise en charge précoce.

Enfant de 8 ans sans antécédent pathologique particulier, qui a été amené aux urgences pédiatriques par ses parents pour un fait inédit, une strangulation de la verge remontant 5 jours auparavant. Le patient avait curieusement introduit sa verge dans un anneau. L'enfant avait caché les faits par peur et pudeur avec l'espoir de pouvoir l'extraire seul. Devant l'installation progressive d'une douleur et une tuméfaction du gland avec l'impossibilité de pouvoir retirer l'anneau, le patient était contraint d'avouer à ses parents qui étaient embarrassés et furieux. A l'admission, il était conscient, sans trouble psychique ni de comportement. L'examen retrouvait un important èdème de la verge en aval d'un anneau fermé très constrictif avec une bonne viabilité du gland (A). Le geste a consisté à une ablation de l'anneau par cisaillement à l'aide d'une pince coupante (B), après une protection préalable de la verge. Après une semaine on note régression complète de l'èdème sans signes urinaires (C).

The fracture of the penis is a rare andrological emergency. We report 2 cases of fracture of the penis including one by false-no coitus. These were young adults aged 34 and 40 respectively. The painful swelling with deviation of the penis was the dominant symptomatology of the clinical picture of the 2 patients. Surgical management was performed with favorable functional results in both cases. The long-term functional prognosis of the fracture of the penis depends on the speed of its management.

Mr AB, âgé de 44 ans, sans antécédents particuliers. Il avait consulté pour des néoformations de la verge évoluant depuis 1 an, accompagné de signes urinaires à type de dysurie et pollakiurie, dans un contexte d'apyrexie et de conservation de l'état général. L'examen des organes génitaux externes mettait en évidence 3 tumeurs fixes, exophytiques, rouges, en "chou-fleur", à centre blanchâtre ulcéré. L'IRM pelvienne montrait une importante infiltration des deux corps caverneux et de l'urètre. Les biopsies ont mis en évidence une tumeur bien différenciée avec prolifération épithéliale papillomateuse et hyperkératose, sans anomalies cytonucléaires. Le patient a subi une pénectomie totale avec dérivation urinaire par urétrostomie périnéale. L'examen anatomopathologique de la pièce opératoire a confirmé le diagnostic de carcinome verruqueux de la verge. L'évolution était favorable, avec un recul de 18 mois, sans récidive locale.

La thrombose de la veine dorsale profonde de la verge (TVDPV) est une urgence rare et mal connue en urologie. Elle nécessite une prise en charge précoce symptomatique et étiologique afin de préserver la fonction érectile et d'éviter les récidives. Nous rapportant à travers notre observation un cas de thrombose veineuse dorsale de la verge révélée par un priapisme spontané non résolutif, et confirmé par un écho-doppler pénien. Apres prise en charge du priapisme et de la TVDPV, l'enquête étiologique a révélé une maladie de Behçet dont le diagnostic a été retenu sur l'association d'un critère majeur qui est l'aphtose buccale, et de 3 critères mineurs que sont: l'aphtose génitale, l'atteinte oculaire, et un test pathergique cutané positif à 24h. Un traitement étiologique a été instauré avec bonne évolution clinique, et conservation de la fonction érectile.

L’épispadias pénien est une malformation urologique rare. Peu de cas sont rapportés dans la littérature. Nous rapportons un cas chez un patient de 30 ans. Le traitement a consisté en une urétroplastie selon le technique de Cantwell-Young, avec de bons résultats fonctionnels.

La gangrène de la verge est une pathologie rare mais grave. Les étiologies sont diverses avec essentiellement le diabète. Nous rapportons le cas d'un patient de 58 ans, diabétique et tabagique chronique ayant présenté une nécrose de la verge et avait bénéficié d'une amputation totale après deux interventions chirurgicale. L'évolution a été marquée par l'installation d'un sepsis et décès du patient.

Deep dorsal penile vein thrombosis (DDPVT)is a rare and little known urologic emergency. It requires an early etiological and symptomatic approach to preserve erectile function and prevent recurrences. This study reports a case of dorsal penile vein thrombosis revealed by spontaneous priapism that didn't resolve adequately and confirmed by penile Doppler ultrasound. After management of priapism and DDPVT, the etiological investigation revealed Behcet's disease whose diagnosis was based on the association of a major criteria, such as oral aphthous ulcers with 3 minor criteria such as: genital aphthous ulcers, ocular involvement, and a positive skin pathergy test within 24h. The patient underwent etiological treatment with good clinical evolution and preservation of erectile function. [ABSTRACT FROM AUTHOR]

Résumé Les automutilations génitales sont des situations rares qui surviennent le plus souvent sur un terrain psychotique. Elles peuvent être à l’origine de complications majeures tant sur le plan urinaire, sexuelle ou esthétique. Nous rapportons un cas d’autosection de la verge chez un patient présentant une dépression profonde et un cas de strangulation de la verge chez un schizophrène. Les aspects épidémiologiques et anatomocliniques sont discutés. La nécessité d’une collaboration entre urologues et psychiatres dans la prise en charge est soulignée. Summary Genital self-mutilation are rare situations that occur most often on a psychotic ground. They can cause major complications both urinary level, sexual or aesthetic. We report a case self-section of the penis in a patient with major depression and a case of strangulation of the penis in a schizophrenic. Epidemiological and pathological aspects are discussed. The need for collaboration between urologists and psychiatrists in management of care is emphasized. [ABSTRACT FROM AUTHOR]

A mature bordered pit in secondary xylem of Pinaceae comprises a circular border of secondary-wall material that protrudes into the tracheid lumen and is punctuated by a centralized aperture through which sap flows. The overarching border encloses a pit chamber within which is a "membrane", or diaphragm, consisting of a central torus and margo strands. Bordered- pit pairs are abundantly present in all woods, and their membranes serve as swinging-diaphragm check valves regulating sap flow between adjoining tracheary elements, simultaneously trapping emboli and particulates in water as it moves from roots to leaves. The cell biology of bordered-pit formation in cambial derivatives of Abies balsamea (L.) Mill. was investigated by light and scanning electron microscopy during early stages of cellular differentiation of cambial derivatives into secondary xylem tracheids. A bordered-pit template (BPT), a bordered-pit organelle (BPO), a bordered-pit basal disk, and additional novel structures were found to be associated with bordered-pit formation. Evidence was found that the membrane does not comprise residual compound middle lamella; rather, the membrane forms de novo as BPO remnants. A cell-biology model and new terminology are introduced to explain how BPTs, BPOs, and basal disks contribute to successive stages in formation of bordered-pit pairs. [ABSTRACT FROM AUTHOR]

Résumé: Objectif: La thrombose veineuse profonde de la verge est une pathologie habituellement bénigne thrombotique veineuse et spontanément régressive. Nous nous proposons d’étudier les caractéristiques épidémiologiques, cliniques, diagnostiques, thérapeutiques et évolutives de cette pathologie. Patients et méthodes: Sept patients entre 13 et 50ans ont consulté pour verge douloureuse. Le diagnostic établi était une thrombose de la veine dorsale profonde de la verge. Un interrogatoire minutieux, un examen clinique et une écho-Doppler pénienne ont été réalisés. Un bilan biologique, à la recherche de troubles de l’hémostase fut également réalisé. Résultats: Tous les patients ont consulté pour une verge douloureuse. Trois patients avaient un priapisme associé. Le diagnostic de certitude a été établi chez tous les patients, grâce à l’échographie Doppler pénienne montrant la thrombose des veines dorsales profondes de la verge. Une hémopathie a été la première cause étiologique (3 cas). Un traitement anticoagulant à base d’héparine à bas poids moléculaire a été aussitôt instauré. Une ponction aspiration avec lavage a été réalisée en cas de priapisme associé avec obtention d’une détumescence satisfaisante. Pour deux patients un traitement spécifique associé (chimiothérapie, corticothérapie) a dû être instauré. Sur le plan évolutif, une dysfonction érectile persistante a été notée chez 2 patients dont un avait des antécédents de priapisme récidivant. Conclusion: La thrombose de la veine dorsale profonde de la verge est une urgence urologique. Son évolution spontanée est souvent favorable. Toutefois, cette affection doit être systématiquement évoquée devant tout œdème et/ou priapisme de la verge chez l’adulte jeune surtout s’il présente des antécédents thromboemboliques. L’association possible à d’autres maladies doit inciter à réaliser un bilan étiologique en fonction des facteurs de risque. Le traitement doit être instauré rapidement sinon le pronostic sexuel peut en être compromis. [Copyright &y& Elsevier]

Summary The Stock Route Network (SRN) of New South Wales (NSW) and Queensland is a large-scale system of predominantly roadside remnant vegetation, which was established in the 1800s to allow livestock to be moved. Proposed changes to the management of the SRN could result in some portions of it being sold to private landholders, or subjected to long-term set-stocking. This may have potentially negative impacts on some of the values of the SRN. One key feature of the SRN is that it covers low-lying parts of the landscape, which are poorly protected by national parks. To quantify this, we specifically analysed a 41 million hectare portion of the SRN which transects the NSW 'wheat-sheep belt', characterising its representation of woody vegetation cover and topography, and contrasting this with the National Reserve System. Our analysis revealed that 55% of stock routes occur in low-lying valley portions of the landscape, compared with only 6% of the National Reserve System. The SRN supports a wide range of vegetation types and, unlike the National Reserve System, is not biased towards heavily forested areas. White Box-Yellow Box-Blakeley's Red Gum woodland, which is listed as critically endangered by the Australian Government, was recorded in 803 (or 17.5%) of the 4575 stock routes in our data set. In contrast, only 10 of the 335 reserves within our spatial study region are known to support small occurrences of this community. Our findings suggest that the protection of the SRN and National Reserve System together may fulfil the 'representation' goal of systematic conservation planning far better than the National Reserve System on its own. Future research should quantify which stock routes in particular should receive priority for protection. [ABSTRACT FROM AUTHOR]

Summary The Stock Route Network (SRN) is a vast system of public land, comprising vegetated strips and small reserves across the eastern length of the Australian continent. Now predominantly following the road system, this network was historically established to allow for the movement of livestock prior to truck and railway transport. Owing to declines in traditional uses, parts of the SRN may now be sold to private landholders, or put under long-term grazing leases, making them unavailable for other emerging uses. This is in spite of the fact that it is widely accepted by researchers, practitioners, graziers and agriculturalists that the SRN holds great natural and cultural value. We conducted a review of scientific and grey literature to determine the known values of the network for biodiversity conservation, cultural heritage, rural communities and Australian society as a whole. We found that the majority of existing literature on the network focuses on New South Wales (NSW) and is of a conservation-based nature. The Stock Route Network supports a wide range of threatened species and communities, with considerable potential for many more to be discovered. The network also holds heritage value for both Indigenous and non-Indigenous Australians. The societal benefits from the SRN are numerous because it provides land for recreation and apiary sites, a source of seed for revegetation projects, a focus for rural tourism, as well as the traditional benefits for stock droving and emergency agistment. In the light of our review, we identified key knowledge gaps pertaining to the values of the SRN and propose a number of options for its future management. Appropriate governance and increased investment in SRN management is now urgently required to ensure that it continues to conserve its many environmental and social values in perpetuity.

Résumé Introduction La maladie de Mondor est une thrombophlébite superficielle rare, touchant historiquement le système veineux thoracique de la femme. Elle peut toutefois s’exprimer chez les deux sexes et intéresser toute la surface cutanée. Observation Nous rapportons l’observation d’un homme de 40 ans, diabétique de type 1, souffrant d’une thrombose de la veine dorsale superficielle de la verge qu’il traitait comme une mycose. Un traitement anti-inflammatoire non stéroïdien complété par une héparine de bas poids moléculaire permettait une évolution favorable en 2 semaines. Conclusion L’étiopathogénie et le traitement de la maladie de Mondor sont encore incomplètement dominés. Certains facteurs prédisposants ont été toutefois soulignés dans la littérature, auxquels il nous paraîtrait intéressant d’intégrer le terrain diabétique, susceptible par ses fréquentes problématiques pelviennes, d’être un irritant inflammatoire veineux local. Introduction Mondor's disease is a rare superficial thrombophlebitis, historically involving the thoracic venous system of women. However, it can occur in both gender and all over the skin. Case report We report a 40-year-old man with type one diabetes who presented with a thrombosis of the superficial dorsal vein of the penis that he treated as a fungal infection. Treatment with non-steroidal anti-inflammatory drugs and low molecular weight heparin contributed to a favorable outcome in 2 weeks. Conclusion Pathogenesis and treatment of Mondor's disease remain incompletely dominated. Some predisposing factors have been highlighted in the literature. It might be interesting to add diabetes, due to its frequent pelvic problems leading to a potential venous inflammatory trigger. [ABSTRACT FROM AUTHOR]

The dynamics of wire rope, and the "vibrating string" problem, is of great interest for numerous applications. It involves multiple complex phenomena which need a rigorous modelization in finite displacements. The difficulties, first arising from the kinematics, are those encountered in the framework of rods mechanics. The motion being three-dimensional, the parametrization which permits to easily describe the material torsion is detailled. The equations of motion are then derived for a linearly elastic thread with a torsion-dependant tension. The couplings exhibited by these equations can be investigated through projection on the spatial modes shapes in the pinned ends case. The obtained system of modal equations shows strict selecting rules based on these spatial shapes, the modulation of the temporal parts only playing an efficiency role in the couplings.

Cuttings from road-verge grass could provide biomass for energy generation, but currently this potential is not exploited. This research assessed the technical, practical and financial feasibility of using grass harvested from road verges as a feedstock in farm-fed anaerobic digestion (AD) plants. The methane potential (191 mL CH 4 g DM −1) and digestion characteristics of verge grass were similar to those of current farm feedstocks; indicating suitability for AD. Ensiling had no significant impact on the biomethane generated. Testing co-digestions of verge grass with current farm feedstocks showed enhanced methane yields, suggesting that verge grass could be a valuable addition to AD feedstock mixes. In a case study of the UK county of Lincolnshire, potential volumes and locations of verge grass biomass were estimated, with capacities and locations of existing AD plants, to assess the potential to supply practical grass volumes. Grass harvesting costs were modelled and compared with other feedstock costs. Finally, the attitudes of AD operators to using verge grass were investigated to understand whether a market for verge grass exists. In a small survey all operators were willing to use it as a feedstock and most were prepared to pay over the estimated harvesting cost. If verge grass was legally recognised as a waste product it could be attractive to AD operators especially where financial incentives to use waste feedstocks are in place. In rural areas, verge grass could be harvested and co-digested by existing farm-fed AD plants, potentially reducing the cost of road verge maintenance and increasing biodiversity. • Verge grass had a methane potential of 222 mL CH 4 g VS −1 or 191 mL CH 4 g DM −1. • This is a similar methane potential to maize. • Adding verge grass to existing AD feedstock mixes can enhance methane production. • Estimated harvesting costs of under £18 t−1 were competitive with other feedstocks. • Four out of five AD plant operators interviewed would pay for verge grass.

Roadside habitats are increasingly being targeted for restoration and conservation. Roadside habitats often exhibit altered soil and plant chemistry due to pollution from maintenance (e.g. de-icing salt), car deterioration, and exhaust. Roadside plants may attract animals due to elevated levels of sodium or nitrogen, but high concentrations of heavy metals and sodium can be toxic, potentially setting an ecological trap. In this study, we determine how roads influence the chemistry of common milkweed (Asclepias syriaca) as it is the primary roadside host plant for the declining monarch butterfly (Danaus plexippus) in the eastern United States. Even though road salt is applied during the winter, we detect enhanced sodium along roads the following growing season. Road salts increase soil sodium, which in turn elevates host-plant foliar sodium (occasionally to toxic levels in <10% of plants) and sodium content in monarch caterpillars feeding on these plants. Sodium levels of milkweed leaves are highest close to the edge of busy roads. Some heavy metals (lead, zinc) are also elevated in roadside soils or plants. Nitrogen content was affected by adjacent agricultural use, but not traffic volume or proximity to a road. Other potential road pollutants (e.g. nickel) were not elevated in soil or plants. Despite a clear signature of road pollution in the chemistry of milkweed, most plants are likely still suitable for developing monarchs. Nonetheless, restoration investments in snowy regions should prioritize sites with lower-traffic density that are further from the road edge to minimize toxic impacts of high sodium. To extend this research to other insects of conservation concern, future work should characterize the nutritional quality of nectar, pollen, and other species of host-plants in roadside habitats. Unlabelled Image • Roadside habitats are important for conservation of insects. • We show some pollutants are elevated in soils, plants, and caterpillars along roads. • Sodium and zinc are highest in leaves that are in close proximity to busy roads. • Management for insect conservation should consider nutrition of roadside plants.

The privacy-oriented cryptocurrencies have built-in anonymity and privacy features that made them very difficult (nearly impossible) to trace funds back to a particular user or successfully seize funds present in a cryptocurrency wallet. Criminals use these currencies in different kinds of malware and DDOS extortion attacks to launder money. While academic research on Bitcoin is becoming more mainstream, the research on privacy-oriented cryptocurrencies is not very common. In this paper, we address the privacy-oriented cryptocurrencies Monero and Verge and investigate which valuable forensic artefacts the software of these cryptocurrencies leaves behind on a computer system. We examine different sources of potential evidence like the volatile memory, network traffic and hard disks of the system running the cryptocurrency software. In almost all sources of evidence there are valuable forensic artefacts. These artefacts vary from mnemonic seed phrases and plain text passphrases in the volatile memory to indicators of the use of a cryptocurrency in the captured network traffic. [ABSTRACT FROM AUTHOR]
