Deniz Güvenliğinde 21. Yüzyıl Tehditlerinin AHP Yöntemiyle Değerlendirilmesi

Güvenlik Stratejileri Dergisi, 2023
In the global political and economic agenda cycle of the 21st century, interest in the seas has spread rapidly. The security of maritime areas, which are central in issues such as transportation, global trade, natural resource reserves, and transfer, has

Mesoscale modeling of smoke transport over the Southeast Asian Maritime Continent: coupling of smoke direct radiative effect below and above the low-level clouds [PDF]

Atmospheric Chemistry and Physics, 2014
The online-coupled Weather Research and Forecasting model with Chemistry (WRF-Chem) is used to simulate the direct and semi-direct radiative impacts of smoke particles over the Southeast Asian Maritime Continent (MC, 10° S–10° N, 90–150° E) during ...

Lagrangian aerosol particle trajectories in a cloud-free marine atmospheric boundary layer: implications for sampling [PDF]

Atmospheric Measurement Techniques
Meteorological processes such as gust fronts, roll structures, internal boundary-layer development and smaller-scale turbulence complicate the physical interpretation of measured aerosol particle properties, fluxes, and transport in the marine ...

Port infrastructure monitoring (Madeira Island, Portugal) through GNSS, inertial systems and physical and numeric models.

Frontiers in Marine Science, 2014
Port infrastructures as breakwaters, are specially designed to be exposed to the most adverse and extreme conditions. Actions such as wind, waves, tides, sediment dynamics and ships anchoring are factors that can weaken these infrastructures over time ...

Characterizing Maritime Snow Canopy Interception in Forested Mountains

Water Resources Research, 2019
Air temperature (Tair) plays an important role in determining how a canopy intercepts snow and apart from event size is the single most important micrometeorological variable found to adequately influence interception rates and magnitude.

Instance Segmentation of Ship Images Based on Multi-Branch Adaptive Feature Fusion and Occluded Region Decoupling in Occluded Scenes

Journal of Marine Science and Engineering
Instance segmentation accurately extracts the position and outline of ships, serving as the foundation for maritime safety tasks such as multi-object tracking, sensor fusion, and collision warning. This study focuses on single-frame segmentation and aims

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
