ANSWER: 23rd September

Explanation:
The people of Saudi Arabia celebrated Saudi National Day on 23rd September 2015. Indo-Saudi diplomatic relations can be traced to the 1940s and upgraded completely in 1954. Foundation of foreign bilateral relations was laid when Crown Prince Faisal visited India in 1955. This was followed by the first ever visit of Head of State, King Saud bin Abdul Aziz Al-Saud in December 1955. Several agreements have been signed including DTAA, BIPPA and cooperation in the field of sports between the two nations. Delhi Declaration marks a major turn in the India-Saudi Arabia relations.

ANSWER: 22nd September

Explanation:
World Rhino Day observed on September 22, 2015 to celebrate 5 species of rhino-Black, White, Greater one-horned, Sumatran and Javan rhinos. World Rhino Day was announced by WWF-South Africa in the year 2010. In India, they day was celebrated with awareness programmes at Kaziranga National Park (Assam), Manas National Park (Assam) and Laokhowa Burachapori (Assam). According to Save the Rhino, there are 29,000 rhinos left across the globe today. Numbers fell from 5 lakh rhinos to 70,000 in 1970.

3) Union Minister for Health and Family Welfare, J. P. Nadda released the NHP/National Health Profile on 22nd September 2015. Which of the following statements are correct about NHP?
a. e-Book/digital version of NHP was released for the first time.
b. This is NHP’s 11th edition
c. NHP 2015 incorporates data from ESIC and Railways for the first time
d. All of the above

ANSWER: All of the above

Explanation:
The National Health Profile/NHP prepared by Central Bureau of Health Intelligence was released on 22nd September 2015. It covers demographic, socio-economic, health status and health finance indicators, along with detailed information on health infrastructure and human resources in health. NHP estimates there is one hospital bed for every 1833 people and the ratio of 1:11000 for the number of government doctors to patients, with Bihar and Maharashtra attaining the worst rations. India currently has 9.4 lakh allopathic doctors, 1.54 lakh dental surgeons and 7.37 lakh AYUSH doctors. Its 400 medical colleges admit an estimated 47000 students annually. NHP was launched in 2005. It seeks to understand data for health indicators of the nation and studied data under following 6 categories-demographic, socio-economic, health finance and health status indicators, comprehensive information on health infrastructure and human resources in health in India.

4) Stanford engineers including that of Indian origin have developed which type of coating to boost and cool solar cells and their efficiency?
a. Transluscent
b. Transparent
c. Opaque
d. None of the above

ANSWER: Transparent

Explanation:
Stanford engineers Shanhui Fan, a professor of electrical engineering, research associate Aaswath P Raman and doctoral candidate Linxiao Zhu at Stanford University in US, have found a solution which is based on a thin, patterned silica material laid on top of a traditional solar cell to boost its efficiency and cool the solar cells. As the heat of the solar cells increases, they become less efficient at covering photons in light into electricity with can be used. Material of the coating is transparent to the visible sunlight powering solar cells, yet captures and emits thermal radiation or heat from infrared rays. In 2014, the same researchers developed an ultrathin material radiating infrared heat directly back toward space without atmospheric warming. For a typical crystalline silicon solar cell with an efficiency of 20 per cent, minus 5 degrees Celsius of cooling would improve absolute cell efficiency by over 1 per cent, a figure that represents a significant gain in energy production. The transparent thermal overlay works best in dry environments.

5) 13 year old Odisha student has won the Community Impact Award at the Google Science Fair in the 13 to 15 years category for developing a water purifier working through waste corn cobs on 22nd September 2015. She is:
a. Sripada Srisai Lalita Prasida
b. Geetika Srisai Lalita Prasida
c. Malini Srisai Lalita Prasida
d. None of the above

ANSWER: Sripada Srisai Lalita Prasida

Explanation:
13 year old Oriya student Sripada Srisai Lalita Prasida, has won the Community Impact Award at the Google Science Fair in the 13-15 years age category for developing a water purifier that works using waste corn cobs. A standard 9th student at DPS Damanjodi in Koratpur district, Prasida was awarded USD 10,000 as prize money apart from receiving mentorship from Google. Prasida used waste corn cobs in order to clean purify water from domestic as well as industrial wastes by applying the principle of adsorption. She based her invention on the principle that waste corn cobs are able to adsorb contaminants like salt oxides, detergent, suspended particles, coloured dyes, oil, grease and certain heavy metals.

6) Google has allowed users to avail which facility after the recent undo technology on 24th September 2015:
a. Block feature
b. Unsubscribe feature
c. Both of the above
d. Neither of the above

ANSWER: Both of the above

Explanation:
Following undo, tech major Google has now introduced block and unsubscribe features for Gmail service allowing users to block email ID and unsubscribe from news letters in just a few clicks. Through the new features, specific email addresses can be blocked in Gmail on the web and future mail will go to spam folder. Users can also opt out of eligible mailing lists directly from the Gmail app. The “undo” option was introduced in June and gmail currently attracts more than 900 million users internationally.

7) US airlines will commence with the testing of a new NASA developed software designed to save time, cut GHG emissions and more. What is the name of this software?
a. Traffic Aware Planner/ TAP
b. Traffic Aware Schedule/TAS
c. Traffic Aware System/TAS
d. None of the above

ANSWER: Traffic Aware Planner/ TAP

Explanation:
US airlines have started testing new software TAP developed by NASA to make traffic aware strategic aircrew requests (TASAR) and this software directly connects to aircraft avionics information hub on the aircraft. It reads the current position and altitude of the aircraft, its flight route and other real-time information that defines the plane’s current situation and active flight plan.

Following this, it automatically looks for numerous routes or altitude changes to save fuel and flight time and display solutions straightaway to flight crew. It also scans nearby air traffic signals to avoid conflicts in flight path changes. TAP can also obtain information for airlines with internet connectivity in the cockpit.
