Biología, comportamiento y taxonomía de dos subespecies de Oleria onega (Ithomiinae, Nymphalidae) en el noreste del Perú
Oleria onega agarista (Felder & Felder) y Oleria onega ssp. Nov. son dos subespecie de Ithomiinae que viven en el noreste del Perú y que están separadas por la Cordillera Escalera. Ambas presentan diferencias de comportamiento de ovoposición (una oviposita en la planta hospedera mientras que la otra lo hace en un objeto cercano) por lo cual se realizaron observaciones de campo, rastreos de potenciales depredadores y estudios genéticos sobre las diferentes poblaciones de dicha especie en la cordillera así como sus zonas de hibridación natural.Tesi
Bilateral Diabetic Knee Neuroarthropathy in a Forty-Year-Old Patient.
Diabetic osteoarthropathy is a rare cause of neuropathic joint disease of the knee; bilateral involvement is even more exceptional. Diagnosis is often made late due to its unspecific symptoms and appropriate surgical management still needs to be defined, due to lack of evidence because of the disease's low incidence. We report the case of a forty-year-old woman with history of diabetes type I who developed bilateral destructive Charcot knee arthropathy. Bilateral total knee arthroplasty was performed in order to achieve maximal functional outcome. Follow-up was marked by bilateral tibial periprosthetic fractures treated by osteosynthesis with a satisfactory outcome. The diagnosis of Charcot arthropathy should always be in mind when dealing with atraumatic joint destruction in diabetic patients. Arthroplasty should be considered as an alternative to arthrodesis in bilateral involvement in young patients
Genetic (RAPD) Diversity between Oleria onega agarista and Oleria onega ssp. ( Ithomiinae , Nymphalidae, Lepidoptera) in North-Eastern Peru
Oleria onega agarista Felder and Felder and Oleria onega ssp. nov. are two Ithomiinae subspecies from north-eastern Peru, that differ for some morphological and behavioural traits. Two contact zones are known near the town of Tarapoto: Ahuashiyacu, where both subspecies cohabit but do not seem to hybridise, and Estero (near the village of Shapaja), where they apparently hybridise. Genetic differences between the two subspecies and between populations were investigated with random amplified polymorphic DNA (RAPD) markers. Both Cluster and Principal Coordinates Analyses (CCoA and PCoA) performed using these data, provided a clear but weak discrimination between the two subspecies. Genetic diversity is much higher within the populations than between them. Moreover, the geographically more distant populations are grouped together by the genetic data. Morphological traits on the wing patterns of the hybrids are intermediary between the two butterflies subspecies, while RAPDs data place them closer to O. onega agarista than to O. onega ssp. The individuals of the Ahuashiyacu population are clearly separated into two groups, those of O. onega ssp. and O. onega agarista, by both morphology and RAPDs data. Moreover, none of those individuals show RAPD similarity with the hybrids, suggesting that hybridisation has not occurred in this populatio
Desaströse Risikogruppe oder wunderliche Alte: Eine narratologische Zeitungsanalyse zum ‹alten› Alter(n) im Altersheim während der Covid-19-Pandemie
Da kein Abstract des Artikels vorhanden ist, finden Sie hier den Beginn der Einleitung:
Die Covid-19-Pandemie ist eine Krise. In Schweizer Zeitungen und in der Fachliteratur wird von der «Corona-Krise» gesprochen oder über «verlängerte» Krisen, «public-health-Krisen», «humanitäre Krisen» und «Krisenzeiten» nachgedacht. Aber diese Krise ist nicht nur medial, sondern auch persönlich zu erfahren gewesen, weil, wie die Journalistin Helena Schmid schreibt, die Pandemie «den Alltag der Menschen verändert» hat: Lockdown und Social Distancing führten nicht zuletzt zu der persönlichen Erfahrung, sich einen Schritt von der gewohnten Welt und vom angewöhnten Umgang mit Anderen getrennt zu fühlen. Der eigene Alltag war nicht mehr zu erkennen, und man fühlte sich zuhause ein wenig wie Erving Goffmans Insassen, die von ihrer «home world» plötzlich abgetrennt sind und sich in einer abgeschlossenen Institution wiederfinden. Die ‹Krise› der Pandemie ist so auch als Übergang von sozialer Stabilität zu sozialer Unsicherheit wahrgenommen worden, die sich im persönlichen Erleben äussert.Aber nicht nur das, wie die Journalistin Dana Liechti anmerkte: «Das Coronavirus beeinflusst unseren Alltag, macht ihn einsamer, angstvoller, trister. Eine Bevölkerungsgruppe trifft die aktuelle Situation besonders hart: die Alten.» Im Mittelpunkt dieser Krisenoptik standen vor allem die als «Risikogruppe» eingestuften Menschen im hohen Alter, die im Altersheim wohnen. Sie galten als stärker gefährdet, einerseits am Virus zu sterben, andererseits sich im Heim kollektiv anzustecken. Deswegen war ihr Alltag stärker und länger durch Einschränkungen und Abschottungen geprägt. Ja, mehr noch: In medialen Darstellungen wurde die Pandemie als «older adult problem» behandelt, was mit dazu beigetragen hat, dass ungleiche und benachteiligende Behandlungen und Lebenseinschränkungen von alten Menschen möglich wurden
Manufacturing of firearms parts: relevant sources of information and contribution in a forensic context
In the context of forensic cases involving firearms, a major issue to address is the identification of the firearm used to discharge questioned elements of ammunition – bullets or cartridge cases – found during the scene investigation. When a questioned firearm is available, reference bullets and cartridge cases are produced through controlled test-fires. The marks left on both the questioned and reference elements of ammunition are analysed before being compared. The processes used to manufacture the firearms tend to influence the type and frequency of some of these marks. Knowing how the questioned firearm was produced is a key element to identify the relevant marks for comparison purposes. Finding this information can be challenging, as it is not necessarily publicly available. After presenting the manufacturing processes used to produce the main parts of firearms in contact with the elements of ammunition, this review includes an updated list of processes used by specific manufacturers, relying not only on the literature. The results highlight the necessity to consider a wide range of sources when gathering information about the manufacturing processes. Apart from general and specialized forensic literature, the online content made available by the manufacturers themselves is also a valuable complementary source of information. Contacting the manufacturers or visiting their premises is sometimes necessary to understand the full extent of the processes and how they can influence the marks of forensic interest
Musicalité de la parole, mise en musique du texte. Fonctions de la ‹ poésie musicale › et de sa mise en musique dans la tragédie en musique
Lully’s and Quinault’s tragédie en musique raises the question of the linkages and coordination between two creative processes in this unique genre. On the one hand, music derives its legitimacy to a large extent from poetry. On the other, a metrical and musical analysis expanding on the account of Le Cerf de la Viéville demonstrates a range of particularities in the structuring of poetry in these works, which at times adapts to pre-existing music, and more frequently anticipates it. Mise en musique, the setting of words to music, is generally in line with poetic dynamics. However, the use of its own means allows it to introduce additional semantic content, marking the strengthening of its autonomy within the artistic system
Agenesis of the long head of the biceps brachii tendon: ignored variations of the anatomy and the next tendon to disappear?
Bilateral agenesis of the long head of the biceps brachial tendon (LHB) is a very rare variation of the anatomy. We report a case of an 18-year-old man with bilateral agenesis of the long head of the biceps brachii tendon. We present initial findings, radiographical examinations and the follow-up of an unusual entity. Diagnosis of agenesis of the LHB can be challenging especially in cases of traumatic shoulder pain. It is not a very known entity because of its rareness. However, it could be associated with other congenital anomalies. The absence of the LHB is easily ignored in the diagnostic process. Clinical examination should be a pitfall, radiological examination is helpful to confirm the suspicion of LHB absence. MRI is often the first choice, although ultrasonography is cheaper and much easier to access and it is an excellent tool to visualise this anatomic variation with empty or shallow intertubercular groove
Quantification of arbuscular mycorrhizal fungi root colonization in wheat, tomato, and leek using absolute qPCR
Arbuscular mycorrhizal fungi (AMF) form symbioses with most terrestrial plants and are known to have a positive effect
on plant growth and health. Different methodologies have been developed to assess the AMF-plant symbiosis. The most
applied method, which involves staining of roots and microscopic observation of the AMF structures, is tedious and time consuming and the results are highly dependent on the observer. Using quantitative polymerase chain reaction (qPCR) to
quantify AMF root colonization represents a reliable, high-throughput technique that allows the assessment of numerous
samples. Quantification with qPCR can be performed through two methods: relative quantification and absolute quantification. In relative quantification, the target gene is normalized with a reference gene. On the other hand, absolute quantification involves the use of a standard curve, for which template DNA is serially diluted. In a previous paper, we validated the primer pair AMG1F and AM1 for a relative quantification approach to assess AMF root colonization in Petunia. Here, we tested the same primers with an absolute quantification approach and compared the results with the traditional microscopy method. We evaluated the qPCR method with three different crops, namely, wheat (cv. Colmetta and Wiwa), tomato, and leek. We observed a strong correlation between microscopy and qPCR for Colmetta (r = 0.90, p < 0.001), Wiwa (r = 0.94, p < 0.001), and tomato (r = 0.93, p < 0.001), but no correlation for leek (r = 0.27, p = 0.268). This highlights the importance of testing the primer pair for each specific crop
Investigating the availability of 3D-printed firearm designs on the clear web.
The release of the plans of the 3D-printed Liberator firearm sparked a wave of new designs from creators worldwide, resulting in an extensive collection of 3D-printed firearm plans, in particular blueprints, and parts available for almost unrestricted download on the internet. Identifying and categorizing the diverse range of 3D-printed firearms and components pose a challenge due to the abundance of designs available. Between 2021 and April 2023, data was collected on over 2,100 3D-printed firearm plans. While blueprints of fully 3D-printed firearms initially dominated the scene, hybrid designs and parts kit completions / conversions (PKC) have gained popularity for their improved reliability and performance. The now highly networked community offers considerable support with detailed instructions and procedures, providing precise guidance for construction. This systematic classification, grouping and structuration of the recorded data on the Clear Web supported the identification of patterns of the main threat trends related to 3D-printed firearms
