Effects of tidal wave modulation on coastal flooding along a tide-river context: Case of the seine estuary
Authors: EI Turki , J Deloffre , R Gilbert , ET Mendoza , E Salameh , N Abcha , N Lecoq , B Laignel
Published: October 2023

Tidal waves modulated over a range of timescales, from inter-daily to inter-annual variations, are responsible for coastal flooding which is enhanced in tide-river environments. The research described here investigates the tidal dynamics interacting with the fluvial component in the Seine estuary (NE France), an excellent natural laboratory for its time-varying flow and the available water-level records provided by tide gauges along the estuary. The tidal signal has been analyzed together with the river discharge during 25 years (1990-2015) in the Seine Bay, including the estuary and the marine tides at Cherbourg, by the use of a series of spectral and physical approaches. The main results highlighted that the tidal modulation is basically induced by the time changes of the harmonic components of M2, S2, N2, and K2 with significant shifts in the middle of the estuary. The estuary takes a flood-dominant behavior when the deformation of tides increases in the river section during the period 1999-2002 with an interaction between the high variability of tidal range and the extreme river discharge. This opposite effect of the river and its resistance is enhanced under higher tidal flow velocity; which increases the water depth and reduces the hydraulic head and the tidal amplification factor in a low turbid estuary. This work carried out in the framework of the SWOT 3MC research program, gives some insights into the complex behavior of tidal propagation in the Seine estuary and its non-stationary dynamics close to the river effects in response to extreme sea levels leading to coastal flooding.

A Computational Method for detecting and evaluating Tankyrase-Binding Motifs v1
Authors: M. Clements Christopher
Published: October 2023

Tankyrases are multifunctional proteins within the poly(ADP-ribose) polymerase family. Known tankyrase binders primarily interact with the scaffolding portion of tankyrases, which comprises five ankyrin repeat cluster (ARC) domains. These domains recognize a specific sequence known as the Tankyrase binding motif (TBM), typically following an octapeptide format characterized by an arginine at position 1 and a glycine at position 6. However, extended and nonconventional TBMs have also been reported. At present, there is no system in place that can easily find and score TBMs. This protocol describes how to use a web-based, public-accessible, computational method (https://shellmanlab.github.io/) we developed to locate and rank all types of potential TBMs. As interest in tankyrases continues to grow across various biological fields, our tool empowers researchers to quickly assess how tankyrases may impact their protein of interest.
Study on the influence of pin shaft clearance on the bearing performance of the hydraulic support
Authors: Du Shunyi , Yang Yang
Published: October 2023

The pin clearance is a significant factor affecting the bearing capacity of the hydraulic support, but the effect of the pin clearance is often neglected in the current studies. Therefore, on the basis of considering the Equal stiffness spring damping system of the column, the dynamic simulation model of the hydraulic support without clearance was constructed to study the static bearing capacity of the hydraulic support. Moreover, as per the contact model of the connecting pin clearance, the dynamic simulation model of the single-pin clearance hydraulic support was established. The effect of single pin clearance on the load of the front and rear columns of the hydraulic support and the transmission force at key bearing points was analyzed. Meanwhile, the influence of single pin clearance at different positions on the bearing capacity of the hydraulic support was compared. Through the design of orthogonal test, the change of the transmission force of the bearing points under the coupling of multi-pin clearance was studied.
Revealing the Community’s Interpretation of Place: Integrated Digital Support to Embed Photovoice Into Placemaking Processes
Authors: García-Esparza Juan A. , Nikšič Matej
Published: October 2023

Rising the quality of life through improving existing living environments remains one of the critical tasks of contemporary urban design. The quality of life is, in part, a subjective matter and shall thus be approached not only through professional measures but must also include participatory inputs. The techniques for including the residents’ points of view are various and greatly depend on the broader context of each case. However, using new ICT and other digitally supported tools is an ongoing trend and can be traced in various places and stages of the process. This article addresses the issue of the participatory reading of characteristics in existing living environments as they are assessed through residents’ eyes. It reviews and analyses two case studies, a Slovenian and a Spanish one, that used the photovoice approach with photography and related supplementary materials to get to know residents’ perceptions towards cultural and natural values that enhance their quality of life. The cases illustrate two different contexts, the urban and the rural one. In both cases, the processes were supported by a digital approach to achieve broader participation in the process, to offer residents an additional channel of expression, to analyse the input data, to disseminate the results, and to encourage a wider community and stakeholder dialogue. The case studies reflect the added value of using digital support in terms of the level of the integration of residents’ voices into the placemaking process. It concludes that the photovoice supported by digital tools can importantly enhance community-oriented urban planning processes.

The work considers an important scientific and practical task of increasing the effectiveness of detecting violations of the integrity of information, in particular digital images, which is its common representation, which is becoming one of the main ones for specialists in the field of information and cyber security today. Undetected, unauthorized changes to information in a timely manner can lead to negative, catastrophic consequences for individuals, enterprises, banks, firms, and for humanity as a whole, when it comes to information that constitutes a state secret, contains data from the military industry, nuclear energy, chemical industry, etc., which determines the relevance of the problem under consideration. The main result 102 of the work is an improved universal method for detecting violations of the integrity of a digital image, ready for practical implementation, the theoretical basis of which is based on the analysis of eigenvalues and eigenvectors of symmetric blocks of the image matrix, which correspond to the original blocks. The paper substantiates the method of symmetrization of the block matrix, which allows to significantly (by more than 23%) reduce computational and, as a result, time costs for image examination in comparison with the time costs of the prototype method. It is proved that for the majority of the obtained symmetric blocks that correspond to the blocks of the original CG, the angle between the eigenvector corresponding to the maximum eigenvalue of the block and the normalized vector of the modules of the eigenvalues is equal to a certain value that does not depend on the specifics of the original image, but is sensitive to its changes, which made it possible to ensure the universality of the method and increase its efficiency in the sense of the accuracy of detecting a violation of the integrity of the image by more than 5%, compared to the analogue. The significance of the obtained results lies in ensuring, due to the use of the proposed method, an increase in the efficiency of the process of detecting violations of the integrity of the image according to the criteria of computing (time) costs for the examination of one image and the accuracy of detection.

 Abstract
The use of asphalt pavement for the displacement of freight vehicles and people is of great importance for the development of a region or a country where strategies that allow to mitigate the constant problems on the roadway, prolonging its useful life must be employed. Mapping to detect pathological manifestations using a Remotely Piloted Aircraft (RPA) popularized as a drone for studies in the area of urban paving in order to maintain quality and enable the extension of its useful life is still at an early stage in Brazilian transport system. In this sense, the objective of this work is to identify the most common imperfections in a paved section of Avenida Archimedes Pereira Lima in the city of Cuiabá-MT and to verify the effectiveness of the RGB camera (Red, Green and Blue) in identifying the defects found according to the Norm DNIT 005/2003 –TER (Defects in flexible and semi-rigid pavements Terminology). Pathological manifestations such as potholes, wear, patches and cracks were identified and distance measurements taken on the photogrammetric image were compared with measurements taken on the road paved with asphalt for each manifestation detected. The results found refer to the potential of the drone in detecting these pathological manifestations, indicating the lack of conservation and appropriate maintenance of the route..

Combination of flexible intramedullary nailing and Ilizarov frame for salvage of femur and humerus nonunion in a girl with osteogenesis imperfecta
Authors: Mingazov E. R. , Foster P. , Popkov A. V. , Popkov D. A.
Published: October 2023

Background Fixation of pathological long bones with telescopic intramedullary rods is well known to be a technically challenging procedure even in specialist centres, with a high complication rate due to rod migration, hardware failure, nonunion or malunion. However there is very little guidance in the literature regarding salvage treatment options when failure occurs.

Aim We demonstrate a surgical technique that can be used for salvage treatment of both femoral and humeral complex nonunions following Fassier-Duval (FD) rodding in a child with osteogenesis imperfecta (OI).

Case description A 13 year-old girl with OI type VIII presented sequentially with nonunion and deformity of the femur then the humerus following previous FD rods in those segments. The femur was also complicated with metallosis between the steel rod and an overlying titanium plate. Both segments were treated with pseudarthrosis debridement, removal of metalwork and stabilisation with hydroxyapatite (HA)-coated flexible intramedullary nails, with temporary Ilizarov frame to provide enough longitudinal and rotational stability to allow immediate weight-bearing. The femur Ilizarov frame was removed after 64 days, and the femur remained straight and fully healed at 2.5 years. The frame time for the humerus was 40 days, complete union was achieved and upper limb function restored and maintained at 9 months.

Discussion The transphyseal telescopic rod is the traditional implant of choice in terms of treating fractures and stabilising osteotomies for deformity in OI. However, it does not provide enough torsional or longitudinal stability by itself to allow early weight-bearing which is detrimental to bone healing in this vulnerable patient group. The incidence of delayed union or nonunion at osteotomy site in telescopic rod application is not negligible: up to 14.5-51.5 %. Although the technique we have shown in this case may not be applied to all complex OI patients, we believe that the combination of flexible intramedullary nails and Ilizarov frame provides a favourable environment for bone healing in complex or revision cases. As a secondary learning point the initial revision surgery to the left femur demonstrated the perils of using a steel rod and a titanium plate in a biologically active environment which in this case lead to metallosis and lysis.

Conclusion We found the technique of HA-coated flexible intramedullary nails combined with the Ilizarov frame effective in the salvage of failed telescopic rods in both femur and humerus and feel this technique can be used as a salvage option in similar cases worldwide. This case also demonstrates the perils of using different metals in combined internal fixation.

Introduction Mycobacterium abscessus species belongs to the group of non-tuberculosis mycobacteria responsible for chronic infections in people with weakened immunity. M. abscessus exist in various ecological niches and are able to colonize artificial surfaces, including medical and surgical instruments/ devices. Due tothe low incidence of M. abscessus as a causative agent of orthopedic infection, a rare clinical case of periprosthetic infection caused by M.abscessus would interest practitioners.

The aim is to present a clinical case of periprosthetic infection caused by M. abscessus.

Materials and methods From the medical records and discharge documents, it was known that female patient X. underwent total hip replacement at her residence hospital. Signs of acute infection of the postoperative wound appeared in the early postoperative period.

Results Three months later, the patient was hospitalized in a specialized institution with a diagnosis of chronic deep periprosthetic infection. During the examination, the mycobacterial etiology of the process was established. During two hospitalizations, the patient underwent 4 consecutive revision surgeries (including muscle plastic surgery and installation of an antimicrobial spacer) and massive parenteral antibiotic therapy for 8 months, including at the outpatient stage, using at least 3 antibacterial agents. After 4 years, the patient does not complain of the infectious process. Postoperative scar is 45 cm. The residual shortening of the right lower limb of 3 cm was compensated by orthopedic shoes.

Discussion Treatment of infection caused by M. abscessus is challenging due to the natural resistance of the pathogen to a wide range of antibacterial drugs. The literature describes separate cases of orthopedic infections caused by this pathogen. All authors agree that the key to successful treatment is a combination of radical surgical debridement and antibacterial therapy using at least three antimicrobial drugs.

Conclusion A rare clinical case of periprosthetic infection caused by Mycobacterium abscessus after primary hip replacement is presented. This infectious agent is a rare pathogen, for which there is no proven therapeutic algorithm. Long-term aggressive antibiotic therapy in combination with stage-by-stage surgical treatment was successful.

Background: Late carpal tunnel syndrome following distal radius fracture is a frequent hazard especially after conservative management. Objective was to assess the association of radiological carpal alignment with the intensity of late carpal tunnel syndrome in old Jordanian women during 1 year of distal radius fracture.
Methods: Our retrospective investigation recruited 100 women, aged more than 50 years with unilateral distal radius fracture managed conservatively during one year of the fracture at Royal Jordanian Rehabilitation center, Jordan, between January 2021 to April 2023. Participants were split into 2 groups. Group I comprised of 50 patients with clinical features of late carpal tunnel syndrome (nocturnal or diurnal) and group II comprised of 50 women without clinical features. CTS-6 assessment tool score (1-6) was recorded to evaluate the intensity of the condition. Electrophysiological and radiological evaluation were performed to record carpal alignment. Student t-test was used to assess the variables.
Results: There was a remarkable discrepancy between groups in terms of the radiological variables of carpal alignment (The average of radio-capitate distance, volar tilt and volar prominence height were: -10.69 mm, -19.89 D angle and 1.45 mm, respectively in group I). There was a positive association between reduction in the variables of carpal alignment and the intensity of late CTS. Volar tilt was positively engaged in the late CTS. The threshold of the volar tilt was -19.41 D angle (p<0.005).
Conclusions: Modification of the carpal tunnel following distal radius fracture with carpal dorsal misalignment leads to late CTS. Reducing volar tilt and volar prominence height and radio-capitate distance are the main remarkable independent anticipators of late CTS in non-surgically treated distal radius fracture.

Background: Elderly patients with high American Society of Anaesthesiologists (ASA) physical status (classes III–IV) have higher reported postoperative mortality for hip fracture. Whether the acceptable time of surgical delay among patients with high ASA scores (classes III–IV) and those with low ASA scores (classes I–II) is different has not been clearly investigated.
Methods: A retrospective cohort study was conducted on 2,035 patients aged ≥60 years who underwent hip fracture surgery between January 2005 and December 2020. The 1-year mortality rate was compared between patients with waiting times beyond the indexed day versus those within the indexed day of 1 to 5. The least time point detecting a significant difference was considered the acceptable time of surgical delay.
Results: There were 1,099 cases (54.0%) in the high ASA group. In the low ASA group, the 1-year mortality rate was significantly lower than the high ASA group (3.5% versus 6.5%, p=0.003), and patients with a waiting time >4 days had a higher mortality rate than those receiving surgery ≤4 days (5.4% vs. 1.8%, OR 2.98, 95%CI 1.40–6.34, p=0.003). For the high ASA group, patients with a waiting time >2 days had a higher mortality rate than those receiving surgery ≤2 days (7.2% versus 3.1%, OR 2.31, 95% CI 1.01–5.25, p=0.036).
Conclusions: The elderly with hip fractures in ASA classes I–II could wait for surgery up to 4 days and 2 days in ASA classes III–IV without a significantly increased 1-year mortality.

Background: Osteoarthritis management includes a myriad of treatment modalities. This study compared the effects of corticosteroid and Hylan G-F 20 injections on knee osteoarthritis outcomes.
Methods: Patients were randomized to receive either corticosteroid or Hylan G-F 20 injections. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index, knee society rating system scores, and visual analog scale scores, collected at baseline, 3 months, and 6 months.
Results: Baseline demographic and clinical parameters were comparable between both groups. The corticosteroid group demonstrated a significant decrease in the WOMAC score over time (p<0.001). Hylan G-F 20 group showed significant improvements in both the WOMAC scores and Visual Analog Scale scores over time (p<0.01). Gender-based sub-analysis suggested both treatments were effective in men, while in women, significant benefits were seen only with Hylan G-F 20.
Conclusions: Both corticosteroid and Hylan G-F 20 demonstrated efficacy in managing knee osteoarthritis, albeit in different domains. The results suggest the need for individualized treatment plans and further research into potential gender-based variations in treatment response.

Background: Tibia is the most commonly fractured long bone, and the prevalence of compound fractures has risen due to an increase in high-energy traumatic incidents. In addressing challenging tibial fractures with significant soft tissue damage, infected tibial nonunion, and compound tibial fractures, medical professionals have turned to specialized treatments, such as Ilizarov ring fixators and limb reconstruction system fixators. These fractures typically cannot be managed effectively with traditional internal fixation methods. To facilitate early weight-bearing, limb lengthening, and efficient wound care, two minimally invasive fixation systems have been developed: the Limb Reconstruction System and the ring fixator.
Methods: The study was conducted on 40 patients with compound tibial shaft fractures treated by Ilizarov ring fixators and limb reconstruction system fixators with the aim to evaluate the functional outcome, union rate and amount of limb lengthening using Ring and ILRS fixators in compound tibial fixators.
Results: In our study, a significant portion of the participants fell within the age range of 28 to 37 years, comprising 45% of the total sample. Furthermore, the majority of the study subjects were male, constituting 65% of the participant pool. The primary mode of injury reported in our study was road traffic accidents, accounting for 77.5%.
Conclusions: The study concluded that LRS fixators show good and promising results like easy to apply, carry, compress, distract and clean while Ilizaro ring fixator is technically demanding, difficult to carry and cumbersome to the patient.
