  • Kozhikode-Wayanad Tunnel Project

    Kerala CM has launched a tunnel road project that would connect Kozhikode with Wayanad.

    Try this PYQ:

    Q.From the ecological point of view, which one of the following assumes importance in being a good link between the Eastern Ghats and the Western Ghats?

    (a) Sathyamangalam Tiger Reserve

    (b) Nallamala Forest

    (c) Nagarhole National Park

    (d) Seshachalam Biosphere Reserve

    Kozhikode-Wayanad Tunnel Project

    • The 7-km tunnel, being described as the third-longest in the country, is part of an 8-km road cutting through sensitive forests and hills of the Western Ghats.
    • Its endpoints are at Maripuzha in Thiruvambady village panchayat (Kozhikode) and Kalladi in Meppadi panchayat (Wayanad).
    • The tunnel is an outcome of a decades-long campaign for an alternative road as the Thamarassery Ghat Road is congested and gets blocked by landslides during heavy monsoon.

    How will the road impact the ecology?

    • The Forest Department has identified the proposed route as a highly sensitive patch comprising evergreen and semi-evergreen forests, marshlands and shola tracts.
    • This region is part of an elephant corridor spread between Wayanad and Nilgiri Hills in Tamil Nadu.
    • Two major rivers, Chaliyar and Kabani that flows to Karnataka, originate from these hills in Wayanad.
    • Eruvazhanjipuzha, a tributary of Chaliyar and the lifeline of settlements in Malappuram and Kozhikode, begins in the other side of the hills.
    • The region, known for torrential rain during the monsoon, has witnessed several landslides, including in 2019 at Kavalappura near Nilambur and at Puthumala, Meppadi in Wayanad.

    Environmental clearance issues

    • Proponents of the project have been stressing that the tunnel will not destroy forest (trees).
    • The MoEFCC guidelines state that the Forest Act would apply not only to surface area but the entire underground area beneath the trees.
    • For tunnel projects, conditions relating to underground mining would be applicable.
    • As the proposed tunnel is 7 km long, it will require emergency exit points and air ventilation wells among other measures, which would impact the forest further.

  • 2020 Nobel for Hepatitis C Virus discovery

    Americans Harvey J Alter and Charles M Rice, and British scientist Michael Houghton were awarded the Nobel Prize for Medicine or Physiology on Monday for the discovery of the hepatitis C virus.

    Try this PYQ:

    Q.Which one of the following statements is not correct? (CSP 2019)

    (a) Hepatitis B virus is transmitted much like HIV.

    (b) Hepatitis B. unlike Hepatitis C, does not have a vaccine.

    (c) Globally, the number of people infected with Hepatitis B and C viruses arc several times more than those infected with HIV.

    (d) Some of those infected with Hepatitis B and C viruses do not show the symptoms for many years.

    Hepatitis C Virus

    • Hepatitis C virus (HCV) is a bloodborne virus and causes liver diseases. It refers to an inflammatory condition of the liver.
    • The novel virus caused several deaths in the 1960s and 1970s — but remained unknown until its discovery in the late 1980s.

    What are other Hepatitis Viruses?

    • Before the discovery of the Hepatitis C virus, two other viruses were known to cause hepatitis in patients.
    • The Hepatitis A virus was known to spread mainly through contaminated food and water and caused a relatively milder form of liver inflammation.
    • Hepatitis B, discovered in the 1960s, was known to transmit mainly through infected blood and caused a more serious form of the disease.
    • Incidentally, the discovery of the Hepatitis B virus too was rewarded with a Nobel Prize in Medicine, given to Baruch Blumberg in 1976. There are vaccines available for this disease now.

    How Hepatitis C came to observation?

    • The discovery and identification of the Hepatitis B virus facilitated the development of a diagnostic test to detect its presence in blood.
    • Thereafter, only blood sanitized from this virus would be given to patients, but it was observed that even this sanitized blood was able to prevent only 20% of the blood-borne hepatitis cases.
    • It was then that the search for the new virus began.

    How is Hepatitis C treated?

    • Presently there is no vaccine available for HCV. However, it can be treated with antiviral medication.
    • Hepatitis A and B are preventable by vaccine.

  • What is Sheltering of Taxes?

    This newscard is an excerpt from an original article published in TH.

    We can expect a statement based question comparing Tax Shelters and Tax Heavens.

    What is a Tax Shelter?

    • A tax shelter is a financial vehicle that an individual can use to help them lower their tax obligation and, thus, keep more of their money.
    • It is a legal way for individuals to “stash” their money and avoid getting it taxed.
    • A tax shelter is entirely different from a tax haven because the latter exists outside the country and its legality can, at times, be questionable.
    • A tax shelter, on the other hand, is entirely legal and keeps all monies within an individual’s home country.

  • What is Ketogenic Diet?

    Ketogenic or Keto Diet is popularly followed as a weight loss diet across the world.

    Try this PYQ:

    Q.Regular intake of fresh fruits and vegetables is recommended in the diet since they are a good source of antioxidants. How do antioxidants help a person maintain health and promote longevity? (CSP 2014)

    (a) They activate the enzymes necessary for vitamin synthesis in the body and help prevent vitamin deficiency.

    (b) They prevent excessive oxidation of carbohydrates, fats and proteins in the body and help avoid unnecessary wastage of energy.

    (c) They neutralize the free radicals produced in the body during metabolism.

    (d) They activate certain genes in the cells of the body and help delay the ageing process.

    What is Ketogenic Diet?

    • The Keto Diet is one of the most popular weight-loss diets the world over.
    • It consists of a high-fat, moderate-protein and low-carb diet.
    • It helps in weight loss by achieving ketosis — a metabolic state where the liver burns body fat and provides fuel for the body, as there is limited access to glucose.

    What constitutes a keto diet?

    • A classic keto generally requires that 90 per cent of a person’s calories come from fat, 6 per cent from protein and 4 per cent from carbs.
    • But there are many versions doing the rounds since this one was designed for children suffering from epilepsy to gain control over their seizures.

    How does it impact the body?

    • If we starve the body of carbohydrate, after burning out the glucose, the liver starts breaking down fats for energy.
    • Ketosis is common in all kinds of fasting, but in a keto diet, when one is feeding it by giving a lot of fats from outside without carbs, it can become mildly toxic.
    • It may lead to many nutrient deficiencies such as carbohydrates, proteins, vitamins (especially vitamin A, D, E, & K) and minerals like calcium, phosphorus, sodium.
    • Extreme carbohydrate restriction can lead to hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog, which may last days to weeks

    What impact does it have on our kidneys?

    • Even the moderate increase in protein needs to be carefully monitored, especially in those who are already suffering from chronic kidney disease, as it could lead to kidney failure.
    • One should get a thorough assessment and make sure they have normal kidney function before choosing this diet.
    • This diet could lead to increased stress on the kidneys and result in kidney stones, as they are made to work overtime.

  • ATAL: World’s Longest Highway Tunnel

    PM Modi has inaugurated the Atal Tunnel at Rohtang at an altitude of above 3,000 metres in Himachal Pradesh.

    Refer this link to read more about Himalayan passes and rivers

    https://www.civilsdaily.com/the-northern-and-northeastern-mountains-part-1/

    Atal Tunnel

    • The 9.02 km-long-tunnel, built by the Border Roads Organisation (BRO), is the world’s longest highway tunnel and connects Manali to Lahaul-Spiti valley.
    • It provides all-weather connectivity to the landlocked valley of Lahaul-Spiti, which remains cut-off for nearly six months in a year as the Rohtang Pass is usually snow-bound between November and April.
    • Before the tunnel construction, the Lahaul Valley used to remain closed for vehicular movement due to bad weather conditions.
    • It reduces the distance by 46 km between Manali and Leh and the travel time by about 4 to 5 hours. It is expected to boost tourism and winter sports in the region.
    • The tunnel, also significant from the military logistics viewpoint, will provide better connectivity to the armed forces in reaching Ladakh.

  • Shaurya Missile and India’s K missiles family

    A successful trial of the nuclear-capable Shaurya missile was conducted by India.

    Shaurya Missile

    • Shaurya is a land-based parallel of the submarine-launched K-15 missile.
    • It is a land variant of short-range SLBM K-15 Sagarika, which has a range of at least 750 kilometres.
    • These ballistic weapons belong to the K missile family — codenamed after late Dr APJ Abdul Kalam — which is launched from Arihant class of nuclear submarines.
    • Because these missiles are to be launched from submarines, they are lighter, smaller and stealthier than their land-based counterparts; the Agni series.

    A look at what this family of missiles is their strategic importance as a nuclear deterrent and their recent tests.

    K Family of missiles

    • The K family of missiles is primarily Submarine Launched Ballistic Missiles (SLBMs), which have been indigenously developed by DRDO.
    • These are named after Dr Kalam, the central figure in India’s missile and space programmes who also served as the 11th President of India.
    • The development of this naval platform launched missiles began in the late 1990s as a step towards completing India’s nuclear triad (land, sea and air-based).

    Strategic importance of SLBMs

    • The capability of being able to launch nuclear weapons submarine platforms has great strategic importance in the context of achieving a nuclear triad, especially in the light of ‘no first use’ policy of India.
    • The sea-based underwater nuclear-capable assets significantly increase the second strike capability of a country and thus boosts its nuclear deterrence.
    • These submarines can not only survive the first strike by the adversary but also can launch a strike in retaliation thus achieving Credible Nuclear Deterrence.
    • The development of these capabilities is important in light of India’s relations with the two neighbours China and Pakistan.

  • What is CBD Oil?

    These days, there are diverse opinions rising regarding the legalization of CBD oil in India after recent controversy rose after the alleged suicide of an actor.

    What is CBD oil?

    • CBD oil is an extract from the cannabis plant.
    • The two main active substances in it are cannabidiol or CBD and delta-9 tetrahydrocannabinol, or THC.
    • The high that is caused by the consumption of cannabis is due to THC.
    • CBD, however, does not cause a “high” or any form of intoxication.
    • CBD oil is made by extracting CBD from the cannabis plant, then diluting it with a carrier oil like coconut or hemp seed oil.

    What are the effects of Cannabidiol?

    • Cannabidiol has effects on the brain, preventing the breakdown of a chemical that aggravates the pain and affects mood, and mental function. It can reduce pain and anxiety.
    • It also reduces psychotic symptoms associated with conditions such as schizophrenia as well as epilepsy.

    Is it legal in India?

    • The Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act) outlaws the recreational use of cannabis.
    • The NDPS Act, however, does not apply to the leaves and seeds of cannabis plants. In case the CBD is extracted from the leaves of the cannabis, then technically it is not illegal.
    • CBD oil manufactured under a licence issued by the Drugs and Cosmetics Act, 1940 can be legally used.
    • However, the use of cannabis as a medicine is not much prevalent in India.
