Effect of thinning on anatomical adaptations of Norway spruce needles [PDF]

Tree Physiology, 2011
Conifers and other trees are constantly adapting to changes in light conditions, water/nutrient supply and temperatures by physiological and morphological modifications of their foliage. However, the relationship between physiological processes and anatomical characteristics of foliage has been little explored in trees.

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Technical Validation of a Training Workstation for Magnet-Based Ultrasound Guidance of Fine-Needle Punctures

Sensors
It has been demonstrated that needle guidance systems can enhance the precision and safety of ultrasound-guided punctures in human medicine. Systems that permit the utilization of commercially available standard needles, instead of those that necessitate

Endoscopic electroincision of challenging benign biliopancreatic strictures

Endoscopy International Open, 2022
Background and study aims Endoscopic drainage of benign biliary and pancreatic strictures can be challenging, especially when tightness of the stenosis does not allow passage of mechanical and pneumatic dilation catheters.

A mass that has no (EBUS) echo. [PDF]

, 2018
We report findings for a patient that underwent endobronchial ultrasound (EBUS) guided transbronchial needle aspiration (TBNA) for diagnostic purposes after an abnormal chest CT. The patient initially presented with cough and shortness of breath.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Ultrasonographic Features of Tuberculous Cervical Lymphadenitis

Journal of Medical Ultrasound, 2014
Making an accurate diagnosis of tuberculous cervical lymphadenitis (TCL) has been a problem to clinicians because it is a versatile masquerader and is often confused with lymphomas or cervical metastases.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Design and evaluation of a mechanical pencil-based actuator for a wasp-inspired needle.

PLoS ONE
In percutaneous interventions, long and thin needles are used to reach deep target locations within the body. However, inserting a long and thin needle into the tissue can cause needle buckling, resulting in poor control of the needle's trajectory and ...
