Surface Modifications on Magnesium Alloys for Biomedical Applications
Magnesium (Mg) alloys have great potential in biomedical applications due to their incomparable properties regarding other metals, such as stainless steels, Co–Cr alloys, and titanium (Ti) alloys. However, when Mg engages with body fluids, its degradation rate increases, inhibiting the complete healing of bone tissue. For this reason, it has been necessary to implement protective coatings to control the rate of degradation.

GPS-aided GEO Augmented Navigation
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The AAI's efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern Communication, navigation and surveillance/Air Traffic Management system over Indian airspace. The project has established 15 Indian reference stations, 3 Indian navigation land uplink stations, 3 Indian mission control centers, and installation of all associated software and communication links. It will be able to help pilots to navigate in the Indian airspace by an accuracy of 3 m. This will be helpful for landing aircraft in marginal weather and difficult approaches like Mangalore and Leh airports.

IBM Building (Honolulu)
The IBM Building is an office building in Honolulu located at 1240 Ala Moana Boulevard. Designed by Vladimir Ossipoff, the building opened in 1962 as the Honolulu headquarters for IBM. It is presently owned by Howard Hughes Corporation, serving as a sales center for their surrounding Ward Village development. Construction of the IBM Building cost $1,500,000 (equivalent to $12,678,218 in 2019). The building was dedicated on October 10, 1962, in a ceremony attended by officials including then-Governor of Hawaii William F. Quinn. The roughly cube-shaped structure is distinguished by the honeycomb structure of its concrete brise soleil, inspired by Polynesian culture and also intended to resemble the punched cards used in the computer industry at the time of its construction. The building was slated for demolition by then-owner GGP Inc. as part of a 2008 redevelopment plan, but public backlash led to its preservation after the planned development area was purchased by Howard Hughes Corporation, which expressed an intent to maintain the IBM Building's name and general appearance. The development company instead renovated the building to use as an information and sales center for their surrounding Ward Village development.

Chirality (Electromagnetism)
300px|thumb|The direction of current flow and induced magnetic flux follow a "handness" relationship The term chiral /ˈkaɪrəl/ describes an object, especially a molecule, which has or produces a non-superposable mirror image of itself. In chemistry, such a molecule is called an enantiomer or is said to exhibit chirality or enantiomerism. The term "chiral" comes from the Greek word for the human hand, which itself exhibits such non-superimposeability of the left hand precisely over the right. Due to the opposition of the fingers and thumbs, no matter how the two hands are oriented, it is impossible for both hands to exactly coincide. Helices, chiral characteristics (properties), chiral media, order, and symmetry all relate to the concept of left- and right-handedness.
