Current Affairs Questions

Explanation :

• A meta material is any material engineered to have a property that is not found in naturally occurring materials.
• They are made from assemblies of multiple elements fashioned from composite materials such as metals and plastics.
• The materials are usually arranged in repeating patterns, at scales that are smaller than the wavelengths of the phenomena they influence.
• These derive their properties not from the properties of the base materials, but from their newly designed structures.

Applications

• Potential applications of meta materials are diverse and include optical filters, medical devices, remote aerospace applications, sensor detection and infrastructure monitoring, smart solar power management, crowd control, radomes, high-frequency battlefield communication and lenses for high-gain antennas, improving ultrasonic sensors, and even shielding structures from earthquakes.
• Meta materials offer the potential to create super-lenses. Such a lens could allow imaging below the diffraction limit that is the minimum resolution that can be achieved by conventional glass lenses.

Explanation :

• Founded in 2002, the Global Fund is a partnership designed to accelerate the end of AIDS, tuberculosis and malaria as epidemic.
• Microsoft founder Bill Gates was one of the first private foundations among many bilateral donors to provide seed money for the partnership.
• Headquartered in Geneva, Switzerland, the Global Fund is the world's largest financier of AIDS, TB, and malaria prevention, treatment, and care programs.
• The Global Fund is a financing mechanism rather than an implementing agency.
• Programs are implemented by in-country partners such as ministries of health, while the Global Fund secretariat, whose staff only have an office in Geneva, monitor the programs.

Explanation :

• Article 72 and Article 161 empowers the President and the Governors respectively, the power to grant pardons, reprieves, respites or remissions of punishment or to suspend, remit or commute the sentence of any person convicted of any offence.
• Remission: It implies reducing the period of the sentence without changing its character. For example, a sentence of rigorous imprisonment for five years may be remitted to rigorous imprisonment for one year.
• Respite: It denotes awarding a lesser sentence in place of one originally awarded due to some special fact, such as the physical disability of a convict or the pregnancy of a woman offender.
• Reprieve: It implies a stay of the execution of a sentence (especially that of death) for a temporary period. Its purpose is to enable the convict to have time to seek pardon or commutation from the President.
