Reibungscharakterisierung bei der Zerspanung von 1.4404/Friction characterisation during machining of 1.4404
Authors: Volke Pascal , Saelzer Jannis , Biermann Dirk 
Published: February 2023

Für die Vorhersage des Werkzeugverschleißes sind neben den Kontaktnormalspannungen und den Relativgeschwindigkeiten die explizite Kenntnis des thermo-mechanischen Belastungskollektives, das im Wesentlichen durch die Reibungsverhältnisse zwischen den Tribopartnern beschrieben wird, von zentraler Bedeutung. Die vorliegende Studie befasst sich mit der Parametrierung eines von der Relativgeschwindigkeit abhängigen Reibungsmodells, welches im weiteren Projektverlauf einen Teil der Datenbasis für die Entwicklung eines Verschleißmodells bildet.

Of central importance for the prediction of tool wear, besides contact normal stresses and relative velocities, is the explicit knowledge of thermo-mechanical loads mainly described by the friction conditions between the tribological partners. The present study focuses on the parameterization of a friction model depending on the relative velocity, which subsequently will form part of the data basis for developing a wear model.

Published: February 2023

Etablierte Verfahren zur Drehwinkelbestimmung an rotierenden Wellen verwenden Codierscheiben oder kabelgebundene Sensorik, welche sich negativ auf die Laufeigenschaften, den Verschleiß oder den Installationsaufwand auswirken können. Schneider et al. demonstrierten ein neuartiges Verfahren zur optischen Drehwinkelbestimmung an lasercodierten Wellen, welches eine kontaktlose Bestimmung des absoluten Drehwinkels ohne Aufbauten oder Verkabelungen an rotierenden Wellen ermöglicht. Gegenwärtig wird die industrielle Anwendung dieses Verfahrens noch durch hohe Belichtungszeiten, große Hardwarekosten und eine mangelnde Echtzeitfähigkeit beschränkt. In diesem Beitrag wird gezeigt, wie durch eine Modularisierung des Messaufbaus und die Verwendung leistungsfähiger Linearsensoren die Belichtungszeit von einigen Millisekunden auf 26 µs reduziert und die Abtastrate auf 1000 Frames*s-1 und mittelfristig 34 000 Frames*s-1 gesteigert werden kann. Messungen an einer rotierenden Welle mit 96,4 U*min-1 bei 1000 Frames*s-1 wurden durchgeführt und in Echtzeit durch einen Field Programmable Gate Array (FPGA) verarbeitet und dekodiert. Die Kosten des Versuchsaufbaus konnten dabei um mehr als den Faktor 20 reduziert werden.

Existing methods for measuring the rotation angle of rotating shafts use encoding disks or cable-based sensors, which can have a negative effect on the running characteristics, abrasion or installation costs. Schneider et al. demonstrated a novel method for optical rotation angle measurement on laser-coded shafts, which allows contactless measurement of the absolute rotation angle without additional setups or cabling. Currently, the industrial application of this method is still limited by high hardware costs and a missing real-time capability. In this work, we show how modularization of the measurement setup, and the use of high-performance linear sensors can reduce the exposure time from a few milliseconds to 26 µs, while the scanning rate can be increased to 1,000 frames*s-1 and 34,000 frames*s-1 in the medium term. Measurements on a rotating shaft at 96,4 rpm at 1,000 frames*s-1 were performed and real-time processed and decoded by a Field Programmable Gate Array (FPGA). The cost of the setup was reduced by a factor more than 20.
Savoir et pouvoir dans les œuvres juridiques d’Alphonse X : une synthèse et une hypothèse
Authors: A. Panateri Daniel 
Published: February 2023

La présente étude a pour objet l’analyse du récit de droit présent dans l’œuvre juridique d’Alphonse X, en particulier dans les Siete Partidas. Dans cette œuvre, le récit en question est centré sur le concept de connaissance comme élément structurant de l’image du pouvoir, image que reflète l’œuvre juridique. Cette image du pouvoir est également produite par le texte lui-même. L’analyse proposée consistera donc en une présentation de différents cas présents dans l’ouvrage susmentionné. Il s’agira d’aborder les divers modes d’action narrative des concepts impliqués dans la construction de ce récit, mais aussi les points communs qui existent entre ces concepts. Ceux-ci supposent l’existence d’un système conceptuel alphonsin dans lequel l’utilisation des notions de savoir et de pouvoir entraîne des différences qui répondent à des stratégies spécifiques au sein même du texte. Ces différences produisent toutefois et, en même temps, un fort sentiment d’unité, renforcé par des phénomènes d’agrégation et de complémentarité.

Published: February 2023

"Социальные медиа занимают прочное место в жизни современного человека. Они стали одним из главных источников информации, которую мы получаем. Подростки проводят в социальных сетях такое невообразимое количество времени, что нельзя упустить возможность использовать эти социальные медиа в их обучении. Современные реалии таковы, что вне школьных стен педагоги и обучающиеся всё чаще общаются через социальные сети и разные мессенджеры – это быстрее, удобнее, проще. Социальные медиа создают новшества в основе процесса обучения, построенного на новых принципах: самостоятельности и активности самих обучающихся, на их сотрудничестве и взаимодействии, на креативности и освоении новых приёмов и методов самообучения. Реализация такого новшества во многом зависит от готовности и инициативы преподавателей экспериментировать и внедрять новые технологии в образовательную практику. Современное общество, к жизни в котором педагоги стараются подготовить детей, подвержено быстрым переменам и, в сущности, мы не знаем, какие знания, умения и навыки понадобятся нашим детям в их будущей взрослой жизни. Именно поэтому необходимо экспериментировать с новыми методами обучения в образовательной практике для того, чтобы научить детей адаптироваться к динамике быстро меняющегося мира. Ключевые слова: социальные медиа, социальные сети, образование, обучение, мессенджеры."
Bladder Scanners in Personal Care Homes
Authors: Hao Qiukui , Mahood Quenby 
Published: February 2023

For older adults with incontinence in a personal care home setting, using a bladder scanner to assist traditional urinary incontinence care may reduce the amount of daytime urine loss and use of incontinence pads without increasing caregivers’ care burden.
Adding a bladder scanner to urinary incontinence care may not impact patient quality of life, mental state, depression, physical function, and level of motivation.
These findings were based on 2 studies, 1 of which lacked a control group and did not directly measure the effect of adding a bladder scanner to urinary incontinence care on patients’ urine loss. This may limit our confidence in the findings.
We did not find any studies that reported on the effect of using bladder scanners in the personal care setting on rates of catheterization, emergency department visits, urinary tract infections, or other harms. We also did not identify any cost-effectiveness studies or evidence-based guidelines that met inclusion criteria for this report.

Introduction: Apparently, Complementary and Alternative Medicine (CAM) is a recognized medical practice that precisely makes use of multiple treatment therapies and techniques in the prevention and management of variety of human disorders. Having a glance at the future, health science students belonging to different universities would take the leadin hospitals and health centers thus this study aims to analyze the level of knowledge, attitude and perception of them towards CAM in Nepal, also aims at awaking students about CAM therapies, related side effects, risks and possible complications.
Methods: A cross sectional descriptive study was organized by enlisting 385 undergraduate students, pharmacy(107) and non-pharmacy (278) which encompasses demographic characteristics, source of information, knowledge, attitudes and perception towards CAM.
Results: Report indicated that predominance of students had good knowledge regarding homeopathy (Pharmacy:81.3%, NP:71.9%, P-value:0.044), herbalmedicine (Pharmacy:62.5%,NP:56.5%, P-value:0.008, acupuncture (Pharmacy:72.9%, Non-Pharmacy:62.2%, P-value:0.073), gingko (Pharmacy:52.3%, Non-Pharmacy:40.6%), ginseng (Pharmacy:52.3, Non-Pharmacy:34.9%, P-value:0.001). In spite employing non reliable origin of CAM information and their mindset that CAM is proceeded by quacks, the preponderance of students had positive attitudes and perception regarding CAM management. However, few non pharmacy students believe that CAM should be adapted by legislation (Pharmacy: 78.5%, Non-Pharmacy: 66.2%, P-value: 0.032), only few believe that CAM is a convenient appendage via traditional medication (Pharmacy: 84.1%, Non-Pharmacy: 70.5%, P-value: 0.018).
Conclusion: Disregarding scanty knowledge in the matter of CAM, students possess forward-looking attitudes and opinion regarding CAM, also express eagerness to increase their knowledge about CAM.

Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was found in Wuhan China which caused the acute respiratory illness and became the pandemic as declared by World Health Organization on March 11, 2020. Viral inclusion bodies have been identified in endothelial cells in a variety of organs. Deep Vein Thrombosis(DVT) is one atypical presentation which is thought to be triggered by endothelial dysfunction and exacerbated by hypoxia in patients with COVID-19.
Methods: It was a single center retrospective study in Kathmandu University Dhulikhel Hospital. All the data were taken between January, 2020 till May, 2021 who were presented in OPD or inpatient department with symptoms of DVT and required admission. Presence or absence or concomitant COVID-19 was tested by RT-PCR test.
Result: There were a total of 52 patients admitted as DVT, among which 26(50%) were male and 26(50%) were female. Twenty patients (38.5%) were COVID-19 positive and 32 (61.5%) were COVID-19 negative. Mean age for among those patients was 50.50±4.8 years, average hospital stay was 6.4±0.6 days, after anticoagulation therapy target INR was reached in 3.8±0.17 days and CVI was present in 14(70%) for COVID positive with DVT. Similarly, mean age was 46.80±3.3 years, average hospital stay was 4.6±0.3 days, after anticoagulation therapy target INR was reached in 3.3±0.21 days and CVI was present in 18(56.65%) with COVID negative with DVT.
Conclusion: COVID-19 is still the mysterious virus and exact mechanism of this disease is still a debate which may need many years to solve. Sometimes DVT can be the only presentation of this disease

Published: February 2023

Introduction: Hemi facial spasm (HFS) and Blepharospasm (BS) is a chronic distressing condition. Botulinum toxin (BoNT) injection is one of its treatment modality. Acquiring the injection and treating the patients overcoming the lockdown hurdles of COVID pandemic has been a major challenge.
Methods: Patients who were treated at Tribhuvan University Teaching Hospital (TUTH) Outpatient Department (OPD) during the COVID pandemic in 2020 and 2021 were included in this study.
Results: Out of 30 patients, 77% were female. 47% were diagnosed with BS whereas the rest with HFS. About 50% of them have had symptoms for an average of 2-5 years before receiving botulinum toxin injection. The mean Jankovic score for patients before BoNT was 2.31(SD: 0.66 range 1-4). 26 patients experienced a decrease in spasm within one week of BoNT injection and had symptomatic relief. The mean Jankovic score at week 1 was 0.63(SD: 1.09 range 1-3) and the difference was statistically significant (p<0.001). After 2 weeks of BoNT therapy, all patients experienced a decrease in spasm with symptomatic improvement. The mean Jankovic score at week 2 was 0.26(SD: 0.44 range 0-1) and the difference was statistically significant (p<0.001). In terms of side effects, 4 patients experienced paresis while 26 patients experienced no side effects. No other systemic side effects were reported.
Conclusion: BoNT injection has a good outcome for HFS and BS, despite its cost and the need for frequent injection. Importing the BoNT from India during the lockdown period of COVID pandemic and patients travelling within the country were challenges that were faced by the patients and doctors to achieve the result.

Published: February 2023

Introduction: Humerus shaft fracture is a common injury representing 1.2-3% of all fractures. It can be managed both conservatively and operatively with various modalities. Among operative, plate osteosynthesis is the most widely accepted method of treatment when conservative treatment is not adequate to achieve union with good functional outcome. Anteromedial plating through anterolateral approach is a safe and reliable approach in plate osteosynthesis.
Methods: A prospective study was conducted in the Department of orthopaedics, Nepal APF hospital, Kathmandu from 2015 February to 2020 February. Forty-four patients who underwent anteromedial plating for humeral shaft fracture were included in the study. Patients were evaluated for functional recovery and progress of fracture healing. Rodrigeuz-Merchan criteria was used to grade the functional outcome.
Results: A total of 44 patients were included in the study with mean age of 36. There were 31 males and 13 females. The majority of patients 31 (70.45%) sustained injury due to road traffic accident followed by fall from height 11 (25%) and direct injury 2(4.55%). The most common fracture pattern was AO /OTA Type A. The mean duration of surgery was 60±15min. Fracture union occurred in less than 4 months in 36 patients (81.81%). Rodriguez Merchan criteria showed majority of the patients had excellent 23(52.27%) and good 15 (34.1%) functional outcomes.
Conclusion: Anteromedial plating provides a safe form of fixation of humeral shaft fracture. It has benefit of supine positioning of the patient during operation with good union rate, less fixation time, lesser complications leading to better functional outcome.

Background: Craniopharyngioma, an epithelial tumor believed to arise from the remnants of Rathke’s pouch, portray approximately 1.2%-4.4% of all intracranial tumors. Due to its inherent domain in the skull base and its liaison with indispensable neurovascular structure, it has still remained an intimidating contest despite an improved dexterity among the neurosurgeons and refinement in neurosurgical gadgetry.Surgical corridor to come down in favor for is elected by the position of optic chiasm, extension of tumor and development of ACoM or ACA (A1).
Methods: A retrospective series study was conducted at Annapurna Neurological Institute and Allied Sciences between January 2016 and August 2021. A total of 20 patients who underwent surgery for histopathologically proven craniopharyngioma was enrolled. Majority of the surgery was performed via a pterional approach while two cases were addressed with a supra ciliary approach and one with a trans nasal trans septal transsphenoidal approach.
Result: The age of presentation among our study group ranged from 5 years to 46 years with a mean age of 28.2 years.The most frequent mode of presentation was headache associated with visual disturbances (visual acuity and visual field). Histopathological analysis disclosed an admantinomatous variant 15 cases and a papillary type in 5 cases. The use of Ommaya reservoir in few selective cases was escorted by the cystic ingredient of the lesion. An endeavor to aggressive surgical approach was accomplished, amidst, excision of tumor was subtotal in 9 %, near total in 36 % and gross total in 45 %. Diabetes insipidus was seen in 36%. We had to endure a case of mortality, who lamentably had a massive sub-arachnoid hemorrhage with a colossal PCA territory infarction on arrival. Post operatively, the mass effect evolved on account of PCA territory infarction.
Conclusion: The magnitude of resection of the tumor is affected by the extension of tumor, consistency of the lesion and position of optic chiasm. Even with an extensive resection, the prospect of recurrence is inordinately high.
“The truth is what happened. It aint what come out of somebody’s mouth”: Truth, Realism, and Relativism in McCarthy’sAll the Pretty Horses
Authors: Elmore Rick , Elmore Jonathan 
Published: February 2023

ABSTRACTWhile scholars agree that John Grady Cole is central to the meaning of All the Pretty Horses, the search for the truth of his character has largely ignored the role of truth in the novel. In this article, the authors argue that one finds in McCarthy’s text a battle over the nature truth, John Grady’s philosophical realism at odds with the world’s moral and metaphysical relativism. To follow the theme of truth in All the Pretty Horses is, the authors contend, to see that, for McCarthy, moral and metaphysical relativism threaten the possibility of a good and just world, this threat illuminating not only the arc of John Grady’s quest but McCarthy’s hope for society itself.
