In the last decades, marine natural products (MNPs), have attracted extensive interest from both chemists and pharmacologists due to their chemical and bioactive diversities. This special issue, collecting total synthesis and structural modification of six different type of bioactive MNPs, is expected to inspire and attract more research effects invested into MNP research.

The knee bracing steel frame (KBF) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. Rather than the beam-column joint, one end of the diagonal brace in KBF is attached to the knee element. Indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

Structural dynamic modification techniques have been available as a design tool for several decades. This article reviews the methodology of the technique including both proportional and complex mode formulations. Issues pertaining to limitations on their use and truncation effects of unmeasured modes are discussed. Also discussed is the use of simplistic elements through higher order elements....

Structural modification of the aromatic fragment significantly affects Cu(i) coordination compounds’ architectures and photophysical properties.

in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...

The ball milling of powders is a non-equilibrium technique (similar to rapid solidification processes) that can be used for production and structural modification of materials. Carbon nanotubes (CNTs) are relatively new materials with excellent combination of properties. They are one of the advanced reinforcement materials for engineering composites. Besides the polymer and ceramic matrices, in...

Influences from environment are inducing structural damage, modification of materials and agglomeration of pollutants, salt and microorganisms which first become visible at outer or inner surfaces of historic buildings. Non-destructive testing methods and especially active thermography are well suited for assessing and monitoring the condition and modification of facades. Active thermography me...

The success of Example-Based Machine Translation (EBMT) often depends upon how efficient the adaptation scheme is. Adaptation primarily aims at modifying retrieved examples to meet the required demands of a given translation task. The present work looks at adaptation for EBMT from English to Hindi. This paper describes a rule-driven adaptation scheme for modifying a retrieved translation exampl...
