How does the biosensor work?

The term “biosensor” is short for “biological sensor.” The device is made up of a transducer and a biological element that may be an enzyme, an antibody or a nucleic acid. The bioelement interacts with the analyte being tested and the biological response is converted into an electrical signal by the transducer.
NITI Aayog’s Ease of Doing Business Report
@UPSC_18
Despite the government claiming to have provided business-friendly environment to investors and attracting huge investments in past decade-and-a-half, Odisha has been categorised as a low-growth State in the country in the latest NITI Aayog survey.The NITI Aayog’s ‘Ease of Doing Business Report: An Enterprise Survey of Indian States’, released, points at more hurdles in setting up new businesses in Odisha compared to other States. The 15-high growth States include Bihar, Uttarakhand, Tripura, Sikkim and Meghalaya.The NITI Aayog and IDFC Institute, its knowledge partner, have classified States on the basis of their average annual real growth rate using State Gross Domestic Product from 2004-05 to 2013-14.We calculated the median average annual growth rate, which turns out to be 8.14%. The States that experienced annual average growth rate equal to or above the median were classified as high-growth States and those with annual growth rate below the median were categorised as low-growth States.At a growth rate of 6.59%, Odisha falls in low-growth category.According to the study, enterprises in high-growth States reported fewer regulatory hurdles. This establishes an empirical link between superior regulatory environment and better economic performances.On average, enterprises reported taking 52 days, 61 days, and 76 days for getting electricity, water, and sewerage connections respectively.The World Bank 2017 Doing Business report ranks India at number 25 for getting electricity connection and it is estimated that getting the connection takes about 46 days. It takes an average of 31 days to get electricity connection in Karnataka, 32 days in Gujarat and around 95 days in Odisha says the report.Odisha is listed among States with lowest proportion of enterprises having knowledge of their environment category. Only 22% of enterprises in Odisha are aware of their category.Similarly, the age distribution of high-growth and low-growth enterprises shows that in general, the share of young enterprises is higher in the high-growth States than in the low-growth States.Around 20% of enterprises in Odisha are young whereas percentage of young enterprises in Bihar is above 70%.
Noted economist Rajiv Kumar today took over as the vice-chairman of government think tank Niti Aayog.

Kumar replaced Arvind Panagariya, an Indian-American economist who left the think tank yesterday to return to academia.

Kumar was a senior fellow at the Centre for Policy Research (CPR). He holds a DPhil in economics from Oxford and a PhD from Lucknow University.

Earlier, he had also served as Secretary General of industry association Ficci.

He was a member of the National Security Advisory Board between 2006 and 2008.

Kumar had also served as the chief economist of the Confederation of Indian Industries (CII) and held senior positions in the Asian Development Bank, the Indian Ministry of Industries, and the Ministry of Finance.
ISRO’S launch of IRNSS-1H failed
@UPSC_2018
@UPSC_18
In a double whammy to the Indian space programme, the PSLV-C39 mission carrying the replacement navigation satellite IRNSS-1H failed.This was the PSLV’s first failure — in what was seen as a routine mission — after 39 continuously successful launches and only the second such instance since 1993.The spacecraft was stuck in the heat shield in the last and fourth stage of the launch vehicle; it did not release into space as planned.All stages of the mission performed well. But there was a mishap. The satellite is still inside the fourth stage.The heat shield did not separate; as a result the satellite is enclosed in the body of the fourth stage.A PSLV flight lasts for 19 minutes. Normally the heat shield separates three minutes into launch but ISRO officials apparently waitied through the entie flight period before conceding the failure.The unprecedented non-release of the 1425-kg satellite halts a dream run of successful launches of the PSLV. The light lift workhorse booster was the pride of ISRO and a commercial success; its only failure was the first developmental launch of September 1993.On the one hand, the launch may somewhat dent the image that the PSLV commands in the global small-to-medium lifting launchers market. It has been easily the most-sought- after vehicle for small satellites of up to 600-700 kg. It has launched 209 satellites of 28 countries since it went commercial in 1999.Antrix Corporation, ISRO’s commercial arm, has firmed up many more client satellites, its chief had earlier said. On the other hand, the failure comes even as ISRO attempts to outsource satellite making to domestic industry. The rocket was carrying the satellite that ISRO assembled by involving a consortium of six Indian small and medium industries.
What is Litmus Paper, how does it work ?

Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly.
The primary raw materials used for making litmus paper are wood cellulose, lichens, and adjunct compounds. Litmus paper, as its name implies, is primarily composed of paper. The paper used to make litmus paper must be free of contaminants that could change the pH of the system it is measuring.
Why The Time is Always Set To 9:41 In Apple Ads?

That time used to be 9:42 . You could see it across various commercials, print ads, and even on Apple's site itself. The explanation was simple: That's the time in the morning that Steve Jobs announced the very first iPhone in 2007. Around 42 minutes into his keynote address, he said, "Today Apple is going to reinvent the phone."
And a picture of the iPhone, displaying the time 9:42, popped up on the screen behind him.
But that all changed in 2010, when the very first iPad was released. When that was revealed, it displayed a different time: 9:41. The time was changed for no reason at all.
Chinese government is trying to woo Kashmiri students
https://t.me/UPSC_2018

Oblivious to the tensions that have recently marked India-China relations, Chinese medical universities have been splurging on advertisements in Kashmiri newspapers, promising “affordable” MBBS courses to students from the State.Fatima Jan, a counsellor with Srinagar-based Fayaz International Counselling Centre, that around 90 China-based and state-run medical universities are currently taking students from Kashmir for courses taught in English.This year, following an advertising blitz, half a dozen placement agencies in Srinagar have received over 200 queries on admission to MBBS courses in China. Similar queries at these centres were less than 20 last year.Traditionally, Bangladesh has been the preferred destination for aspirants from the Valley.Apart from MBBS, students in Jammu and Kashmir are looking at China for other specialised courses.This year, counsellors are also offering MBBS seats in countries such as Kazakhstan, Georgia, and Kyrgyzstan.A Kashmir-like climate and cultural links, especially food, “attract students to Central Asian countries.”

After two decades Assam government issued orders for AFSPA
@UPSC_2018
@UPSC_18

For the first time since 1990, the Assam government issued orders declaring the State a “disturbed area”, imposing the Armed Forces Special Powers Act (AFSPA) for six months.Such orders were earlier issued by the Union Home Ministry, which recently gave up its power and asked the State government to decide on continuing the enforcement of the AFSPA in the State.Under Section 3 of the Act, it can be invoked in places “where the use of armed forces in aid of the civil power is necessary”.Except in the case of Tripura and Manipur, the Centre had been issuing such notifications for Assam, Nagaland, Arunachal Pradesh and Meghalaya. The decision comes a year after the BJP came to power in Assam in 2016.The AFSPA gives powers to the Army and Central forces deployed in “disturbed areas” to kill anyone acting in contravention of the law, arrest and search any premises without a warrant.On August 4, the Home Ministry extended the AFSPA in Assam for 27 days, which expired on August 31.

WB govt to distribute UNHCR refugee cards to Rohigya children
@UPSC_18

The West Bengal government will distribute identity cards issued by the United Nations High Commissioner for Refugees (UNHCR) to Rohigya children lodged in the juvenile justice homes of the State.The UNHCR says some 16,500 Rohingya from Myanmar are registered with it in India.The government issues long-term visas to refugees which ease their access to public services and employment in the private sector.Because of some recent changes to the documentation processes, some refugees have reportedly been facing challenges in accessing public services and opening bank accounts.The UNHCR advocates that the long-term visas and refugee cards continue to be recognised to facilitate their access to these services.While there are no fixed settlement of Rohingyas in West Bengal, most of them are in prisons.The data available for the period till August 2015 show that 83 Rohingyas, including women and children, are lodged in prisons and 27 had completed their term.
Model Answer:

Write a note on the principles of stem cell therapy and latest advancements in this field?

Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition.

Bone marrow transplant is the most widely used stem-cell therapy, but some therapies derived from umbilical cord blood are also in use. Research is underway to develop various sources for stem cells, and to apply stem-cell treatments for neurodegenerative diseases and conditions such as diabetes, heart disease, and other conditions.

Stem-cell therapy has become controversial following developments such as the ability of scientists to isolate and culture embryonic stem cells, to create stem cells using somatic cell nuclear transfer and their use of techniques to create induced pluripotent stem cells. This controversy is often related to abortion politics and to human cloning. Additionally, efforts to market treatments based on transplant of stored umbilical cord blood have been controversial.

Some of its applications are :

a. regeneration of lost limbs or other bodily organs

b, to suppress the expression of some genes, particularly for preventing cancerous genes to develop

c. For treatment in diabetes, health loss, teeth replacement etc.

d. Now in UK, researches have explored possibility of treating foetuses by stem cell therapy to remove genital defects.

But use of stem cell therapy has been surrounded by ethical issues also:

a. use of embryonic blood for stem cells, results in their manipulation causing ethical concerns

b. Stem cell therapy is also considered ideal for human cloning .

Thus, given the immense potential of stem cells, world medical community should evolve ethical guidelines for the development and regulation of stem cell therapy.
How does an optical fiber work?

Imagine what they'd make of modern fiber-optic cables "pipes" that can carry telephone calls and emails right around the world in a seventh of a second! Photo: Light pipe: fiber optics means sending light beams down thin strands of plastic or glass by making them bounce repeatedly off the walls.
Fiber optics is faster than most other transmission mediums. The signal has a constrained loss rate, which means that very little of a signal is lost over rather long distances.
`RythuVariBhu Survey’ from Sept. 15 to Dec. 15

The special drive to be taken up for cleansing the land records in the State, 'RythuVariBhu Survey', from September 15 to December 15 would have the main objective of ensuring the proper reach of investment support to farmers, proposed to be implemented from kharif next.

Official sources involved in the exercise from the beginning stated that the special drive had been necessitated since the data collection about lands being cultivated by the Agriculture Department had no sanctity and it had to have the stamp of Revenue Department.

The special drive would help deletion of lands from the record of cultivable lands following their alienation for projects, industries, roads, canals, railway lines, power lines, real estate and other non-agricultural purposes.

A sizeable chunk of such lands are in duplication as they are also shown in the agricultural land extent, the sources noted.

There’s every chance for irregularities to claim the investment support assistance to be given by the government by ineligible persons or for the land which is not in use for agriculture in the absence of clarity in land records, the sources pointed out.

As decided already, any dispute over assigned lands, ceiling lands, forest lands, urban lands and other government and private lands would be kept aside as Category-B lands for re-survey later.

Apart from reconciling the 1B land data of the Revenue Department with the data collected by the Agriculture Department in RythuSamagra Survey with Agriculture Extension Officers during May-July, the special drive will help smooth transition of records related to succession and regularisation of sada 'binamas' without people making rounds of revenue offices”, Agriculture Secretary C. Parthasarathi told The Hindu .
Law Ministry opposed transgenders recognition as ‘third gender’

https://t.me/UPSC_2018

The NDA government has dropped plans to recognise transgender persons as the ‘third gender’ in the country’s labour law framework.

In 2014, the Supreme Court had for the first time recognised transgender persons as the ‘third gender’ and asked the Centre and the States to give them equal opportunities in education and employment.

But now this reform, part of the Labour Ministry’s draft law to codify wages and aimed at protecting transgender workers from discrimination, has been shelved following reservations expressed by the Law Ministry.

“We had proposed inserting clauses for recognising the rights of transgender workers in all the four labour codes. However, the Law Ministry objected, citing the General Clauses Act of 1897, according to which ‘transgenders’ fall within the definition of ‘person’. It was then decided that there was no need to add a separate clause for them,” a senior Labour and Employment Ministry officer.

The Wages Code Bill was drafted under an exercise to rationalise the country’s 44 labour laws into four codes covering all the regulations pertaining to wages, industrial relations, social security and safety, and health and working conditions.

The draft Labour Code on Wages Bill prepared by the Labour Ministry in 2015 had provisions prohibiting discrimination against transgender persons in the payment of wages.
