bharat ias - New Wi-Fi system to offer super-fast connectivity

New Wi-Fi system to offer super-fast connectivity

New Wi-Fi system to offer super-fast connectivity ·         Scientists have developed a new wireless Internet based on infrared rays that is reportedly 100 times faster than existing Wi-Fi networks. ·         The wireless network developed by researchers at Eindhoven University of Technology in The Netherlands not only has a huge capacity — more than 40 Gigabits per second (Gbit/s) — but does away with the need to share Wi-Fi as every device gets its own ray of light. ·         The wireless data comes from a few central ‘light antennas’, which can be mounted on the ceiling, that are able to precisely direct the rays of light supplied by an optical fibre. ·         The antennas contain a pair of gratings that radiate light rays of different wavelengths at different angles (‘passive diffraction gratings’). ·         Changing the light wavelengths also changes the direction of the ray of light. A safe infrared wavelength is used that does not reach the retina in the eye. Tracks precise location ·         The network tracks the precise location of every wireless device using its radio signal transmitted in the return direction ·         Different devices are assigned different wavelengths by the same light antenna and so do not have to share capacity. ·         Current Wi-Fi uses radio signals with a frequency of 2.5 or five gigahertz. ·         The new system uses infrared light with wavelengths of 1,500 nanometres and higher. ·         Researchers managed to achieve a speed of 42.8 Gbit/s over a distance of 2.5 metres. ·         The system has so far used the light rays only to download; uploads are still done using radio signals since in most applications much less capacity is needed for uploading.    ...

bharat ias - National Health Policy, 2017:

National Health Policy, 2017:

National Health Policy, 2017: Why in news? The National Health Policy was cleared by the Union Cabinet.  Features ·         It will replace the previous policy which was framed 15 years ago in 2002. ·          It aims at providing healthcare in an “assured manner” to all by addressing current and emerging challenges arising from the ever changing socio-economic, epidemiological and technological scenarios. ·         the policy advocates a progressively incremental assurance-based approach.   Highlights of National Health Policy, 2017 ·         It aims to raise public healthcare expenditure to 2.5% of GDP from current 1.14%, with more than two-thirds of those resources going towards primary healthcare. ·         It envisages providing a larger package of assured comprehensive primary healthcare through the ‘Health and Wellness Centers’. ·         It is a comprehensive package that will include care for major non-communicable diseases (NCDs), geriatric healthcare, mental health, palliative care and rehabilitative care services. ·         It advocates allocating major proportion (two-thirds or more) of resources to primary care. ·          It proposes free diagnostics, free drugs and free emergency and essential healthcare services in all public hospitals in order to provide healthcare access and financial protection. ·         It seeks to establish regular tracking of disability adjusted life years (DALY) Index as a measure of burden of disease and its major categories trends by 2022 ·         . It aims to improve and strengthen the regulatory environment by putting in place systems for setting standards and ensuring quality of healthcare. ·          It also looks at reforms in the existing regulatory systems both for easing drugs and devices manufacturing to promote Make in India and also reforming medical education. ·         It advocates development of mid-level service providers, public health cadre, nurse practitioners to improve availability of appropriate health human resource. ·         It aims to ensure availability of 2 beds per 1000 population to enable access within golden hour. ·          It proposes to increase life expectancy from 67.5 to 70 years by 2025. ·         It aims to reduce total fertility rate (TFR) to 2.1 at sub-national and national level by 2025. ·         It also aims to reduce mortality rate (MR) of children under 5 years of age to 23 per 1000 by 2025 and maternal mortality rate (MMR) to 100 by 2020. It also aims to reduce infant mortality rate to 28 by 2019 and reduce neo-natal mortality to 16 and still birth rate to ‘single digit’ by 2025. ·          It proposes universal screening. ·         As per the new Policy, the National Healthcare Standards Organisation (NHSO) will decide the standards of private and public health institutions, and an empowered tribunal will deal with grievances ·         The policy envisages a three-dimensional integration of AYUSH systems encompassing cross referrals, co-location and integrative practices across systems of medicines. ·         This has a huge potential for effective prevention and therapy that is safe and cost-effective.Yoga would be introduced much more widely in schools and work places as part of promotion of good health. ·         Many of the disease-specific targets have been announced by the Policy — such as eliminating kala-azar and filariasis by 2017, leprosy by 2018 and measles by 2020. ·         The policy proposed to eliminate tuberculosis by 2025. Drawbacks of the policy ·         The new policy repeats several old ideas, and fails to fulfil 2015 promise of a Right to Health. ·         The policy duplicates portions of the Health section of Finance Minister 2017 Budget speech. ·         It fails to make health a justiciable right in the way the Right to Education 2005 did for school education. ·         The policies reference to an “assurance-based approach” abandons a radical change proposed in the draft policy of 2015 where National Health Rights Act aimed at making health a right. ·         Diagnostics, drugs and essential health care services are already free in many states. ·         The policy says that 2.5% GDP spend target for Health would be met by 2025.But the HLEG report of 2011, quoted by the 12th Plan document, had set the same target for the Plan that ends at the end of this march 2017. ·          health cess was a pathbreaking idea in the Health Ministry’s draft policy.But now it has been rejected, with health officials maintaining that there is no dearth of funds.      ...

bharat ias - Gauntlet at Sukma

Gauntlet at Sukma

Gauntlet at Sukma   Context The Maoist ambush suggests that the state has a lot more to do to establish its writ  What has happened? Deadly ambush by Maoists in Chhattisgarh’s Sukma district  Can’t let loose Wake up call for security forces: The incident should serve as a wake-up call for the security forces to beef up their standard operating procedures, especially intelligence-gathering capabilities, in the Maoist heartland in central India In 2016, reportedly there was a 15% drop in left-wing extremist incidents, but the current incident proves otherwise  Half Measures The government has over the past decade taken a patchy approach to bringing the so-called “red corridor” under its control No visible civil administration: The only presence of the state consistently visible across the region has been of the security forces, not of the civil administration Counter-insurgency operations by the security forces have often been undermined by poor intelligence, flagging alertness of the security forces and the absence of a multi-layered political strategy  Conclusion   Any fight against non-state actors will be effective only when the state puts forward its combined might to exhibit what it can — and indeed must — provide to the people...

bharat ias - bold foreign policy

bold foreign policy

For a bold foreign policy  Context National interest is not served by avoiding problems left over by a previous order  Moving to a multipolar world Increasing Leverage of China: The China-led Asian Infrastructure Investment Bank & the New Development Bank of the BRICS could provide the required $8-15 trillion, marginalising the World Bank. China is projecting the One Belt, One Road (OBOR) initiative as a replacement for the U.S.-led post-1950 multilateral institutions.  Trump’s Approach He Questions Role of the UN: Trump Favoring bilateral Deals instead of International Co-operation Resetting priorities of the UN away from peacekeeping, environment and human rights to trade Prepared to limit imports and boost exports even at the cost of upsetting long-standing agreements and allies Impact: Other rich countries like Japan and the U.K. are likely to adopt this new template of Trump (America First) doing away with concessions to others consequences for the World Trade Organisation, in particular if the WTO dispute resolution panels rule against the U.S., leading to a questioning of the rule-based system itself Sees China as greatest Threat:The combination of military and economic strength creates a strategic situation where, like in the Cold War, the U.S. will need to seek a “constructive relationship” in Asia rather than dominance and may join the OBOR  Asian connectivity and India Chinese exports to the U.S. are declining, the shift to a consumption-driven economy will open markets for U.S. goods India is more vulnerable with two-thirds of the exports of the $150-billion IT industry to the U.S. and the ‘Make in India’ strategy colliding with Mr. Trump’s priorities, requiring India to make strategic choices.  Way ahead   Need a bold vision on Kashmir and must not just seek to isolate Pakistan Should join the OBOR, while maintaining our reservations on its branch passing through Kashmir, and become part of the growing Asian market With world-class cyber-space-biotech capability, we should reconsider large-scale purchases from abroad for massive investment in cyber security and the related digital economy that will make the ‘Digital India’ initiative into ‘Digital Asia’. ...
