'Un engin de torture, une baïonnette à crochets; une arme blanche déshonorée': an historical-archaeological evaluation of the Sawback bayonets of the Deutsches Heer
The Imperial German Army (Deutsches Herr) was unique among the combatants in World War One (WW1) in issuing to a proportion of its soldiers a bayonet whose blade back was fashioned as a saw. A common belief developed quickly among the Allies that these sawback bayonets were weapons specifically intended to inflict a particularly vicious type of wound. After setting out the origins of this class of weapon and explaining their real purpose, the two main types of sawback bayonet available to the Deutsches Heer during WW1 are then concisely described. Its reputation as a weapon of especial barbarity is outlined, along with an overview of bayonet use in combat between the mid-nineteenth century and 1918, as evidenced by official sources, highlighting the lack of any specific contemporary references to the use of or the wounds caused by sawback bayonets. The article concludes by detailing the contemporary German sources relevant to its withdrawal from service use in 1917.

The unpredictable diagnosis of pulmonary nodules
Pulmonary nodules are single or multiple rounded opacities with a size of minimum 1 cm diameter visualised in the lung parenchyma. From an anatomopathological point of view, they can be benign or malignant. Most often, these nodules are asymptomatic or with minimal symptoms. Now, we present the case of a 62-year-old patient, a smoker, with exposure to occupational respiratory noxious (cellulose industry – 10 years and printing industry – 30 years) without significant personal respiratory pathological history. He has dyspnoea on moderate exertion, irritable cough, myalgia, arthralgia and physical asthenia. The physical examination reveals the presence of a right bayonet sign. Biologically, an inflammatory syndrome was present, the urine test shows no pathological changes, but the imaging is intriguing. On the other side, the imagistic workup [chest X-ray and computed tomography (CT) scan] was quite surprising: micro/macronodular opacities with variable wall thickness, irregular contours and a tendency to confluence at the bilateral lower lobes level. A bronchoscopy was also performed with bronchioloalveolar lavage (BAL) in the right upper lobe (RUL) and bronchial biopsy at the level of the right upper ventral. The hypotheses are multiple: pulmonary rheumatoid nodules, polyangiitis with granulomatosis, lymphangitis carcinomatosis and tuberculosis. Thoracic surgery determined the diagnosis.

Importance Classification Method for Signalized Intersections Based on the SOM-K-GMM Clustering Algorithm
Urbanization has intensified traffic loads, posing significant challenges to the efficiency and stability of urban road networks. Overloaded nodes risk congestion, thus making accurate intersection importance classification essential for resource optimization. This study proposes a hybrid clustering method that combines Self-Organizing Maps (SOMs), K-Means, and the Gaussian Mixture Model (GMM), which is supported by the Traffic Flow–Network Topology–Social Economy (TNS) evaluation framework. This framework integrates three dimensions—traffic flow, road network topology, and socio-economic features—capturing six key indicators: intersection saturation, traffic flow balance, mileage coverage, capacity, betweenness efficiency, and node activity. The SOMs method determines the optimal k value and centroids for K-Means, while GMM validates the cluster membership probabilities. The proposed model achieved a silhouette coefficient of 0.737, a Davies–Bouldin index of 1.003, and a Calinski–Harabasz index of 57.688, with the silhouette coefficient improving by 78.1% over SOMs alone, 65.2% over K-Means, and 11.5% over SOM-K-Means, thus demonstrating high robustness. The intersection importance ranking was conducted using the Mahalanobis distance method, and it was validated on 40 intersections within the road network of Zibo City. By comparing the importance rankings across static, off-peak, morning peak, and evening peak periods, a dynamic ranking approach is proposed. This method provides a robust basis for optimizing resource allocation and traffic management at urban intersections.

Partial Redesign of an Accelerator Driven System Target for Optimizing the Heat Removal and Minimizing the Pressure Drops
Accelerator Driven Systems (ADS) seem to be a good solution for safe nuclear waste transmutation. One of the most important challenges for this kind of machine is the target design, particularly for what concerning the target cooling system. In order to optimize this component a CFD-based approach has been chosen. After the definition of a reference design (Be target cooled by He), some parameters have been varied in order to optimize the thermal-fluid-dynamic features. The final optimized target design has an increased security margin for what regarding Be melting and reduces the maximum coolant velocity (and consequently even more the pressure drops).

Cast immobilization in bayonet position versus reduction and pin fixation of overriding distal metaphyseal radius fractures in children under ten years of age: A case control study
Purpose
Completely displaced distal radius fractures in children have been traditionally reduced and immobilized with a cast or pin fixed. Cast immobilization leaving the fracture displaced in the bayonet position has been recently suggested as a non-invasive and effective treatment alternative. This is a pilot comparative study between reduction and no reduction.
Methods
We assessed subjective, functional and radiographic outcome after a minimum 2.5-year follow-up in 12 children under ten years of age who had sustained a completely displaced metaphyseal radius fracture, which had been immobilized leaving the fracture in an overriding position (shortening 3 mm to 9 mm). A total of 12 age-matched patients, whose similar fractures were reduced and pin fixed, were chosen for controls.
Results
At follow-up none of the 24 patients had visible forearm deformity and the maximal angulation in radiographs was 5° Forearm and wrist movement was restored (< 10° of discrepancy) in all 24 patients. Grip strength ratio was normal in all but three surgically treated patients. All patients had returned to their previous activities. One operatively treated boy who was re-operated on reported of pain (visual analogue scale 2).
Conclusion
The results of this study do not demonstrate the superiority of reduction and pin fixation over cast immobilization in the bayonet position of closed overriding distal metaphyseal radius fractures in children under ten years with normal neurovascular findings.

Experimental Investigation on CIRCE-HERO for the EU DEMO PbLi/Water Heat Exchanger Development
The present paper describes the experimental campaign executed at the ENEA Brasimone Research Centre aiming at supporting the development of a PbLi/water heat exchanger suitable for the lithium–lead loops of the dual coolant lithium lead and the water cooled lithium lead breeding blankets of the EU DEMO fusion reactor. The experiments were performed in a test section named HERO, installed inside the main vessel of the lead–bismuth eutectic-cooled pool-type facility CIRCE. The test section hosts a steam generator bayonet tube mock-up in relevant scale, which was selected as a promising configuration for DEMO purposes. For the thermal-hydraulic characterization of the component, five tests were executed at different water pressures (6, 8, 12 MPa, two tests at 10 MPa), and liquid metal flow rates (40, 33, 27, 20, 10 kg/s). The experimental outcomes proved the technological feasibility of this novel steam generator and its suitability for the DEMO PbLi loops. The activity was completed with a post-test analysis using two versions of the system code RELAP5. Because the experiments were executed with lead–bismuth eutectic, a scaling analysis is proposed to find the equivalence with PbLi. RELAP5 code was applied to recalculate the experimental data using PbLi as working fluid.

Experimental and Numerical Investigations into Heat Transfer Using a Jet Cooler in High-Pressure Die Casting
During high-pressure die casting, a significant amount of heat is dissipated via the liquid-cooled channels in the die. The jet cooler, also known as the die insert or bubbler, is one of the most commonly used cooling methods. Nowadays, foundries casting engineered products rely on numerical simulations using commercial software to determine cooling efficiency, which requires precise input data. However, the literature lacks sufficient investigations to describe the spatial distribution of the heat transfer coefficient in the jet cooler. In this study, we propose a solver using the open-source CFD package OpenFOAM and free library for nonlinear optimization NLopt for the inverse heat conduction problem that returns the desired distribution of the heat transfer coefficient. The experimental temperature measurements using multiple thermocouples are considered the input data. The robustness, efficiency, and accuracy of the model are rigorously tested and confirmed. Additionally, temperature measurements of the real jet cooler are presented.
