Bio-Fuel: Explained

Context: The use of food crops to generate bio-fuels can put burden on the resources of India, which demands for change in the definition of bio-fuels.

Biofuels are alternative fuels produced from biomass and used for transportation. 

There are two major biofuel sectors: 

  • Bio-gasoline from sugar-based bioethanol.
  • Biodiesel from vegetable oils or fatty acid methyl esters (FAME).  
Biomass to liquified

Need for Alternative Fuel Options 

Global transportation sector is facing three major challenges, namely 

  • Depletion of fossil fuels.
  • Volatility in crude oil prices.
  • Stringent environmental regulations. 

Alternative fuels specific to geographies can address these issues. Ethanol is considered to be one of most suitable alternative blending, transportation fuel due to its better fuel quality (ethanol has a higher octane number) and environmental benefits.

Defnition of Biofule and Global Regulation 

Since 2008, European regulations (such as the RED II directive) while differntiating provide for two kinds of biofuels:

  • Conventional biofuels: First generation biofuels from agricultural raw materials that can threaten food security or have a negative impact on land use changes
  • Advanced biofuels:
    • Second Generartion: These fuels are derived from non-edible vegetal resources.
    • Third Generartion: These fuels are derived from micro-organisms such as algae or yeasts.
Biofuel Feedstocks

Biofuel consumption mainly depends on legal constraints on blending and on the fuel demand trends. They were mainly used in road transport in 2020, but new applications in the maritime and air sector are being developed. 

Data 

According to the International Energy Agency, to achieve net-zero emissions by 2050 globally, sustainable biofuel production needs to triple by 2030 to fuel modes that have few other mitigation options.

Biofuels vs. Electric Vehicles (EVs)

Transitioning to EVs requires replacing existing internal combustion engine (ICE) vehicles and infrastructure, which is capital-intensive and can have environmental concerns related to the mining of critical minerals for batteries.

Case of India  

  • High Import Dependence: India’s import dependence on crude oil and products stood at an all-time high of 87.3% in FY2023, and 25.8% of the country’s import bill was spent on it. 
  • High Demand of Crude and its Product: India has the third-largest crude and product demand in the world with significant room for consumption growth. 
  • Demand of Transportation Sector for Petrol  
    • Nearly 60 per cent of our petrol demand comes from two-wheelers, which cater to the mobility needs of citizens across the economic spectrum.  
    • The remaining 40 per cent demand is from four-wheelers and this share is likely to increase. 
  • Government Programme: India launched its ethanol blending programme in 2003 and in 2022, India’s blending programme achieved the significant milestone of 10 per cent ethanol blending in petrol. 
  • Ethanol Supply:  
    • Ethanol producers supplied nearly 430 crore liters of ethanol in 2022. 
    • Much of India’s supply of ethanol for the blending programme comes from first-generation production using food crops, mostly sugarcane (84 per cent) and grain (16 per cent). 
  • Prospect of Second-generation (2G) technologies 
    • Investments in second-generation (2G) technologies for ethanol production have been slow. 
    • Indian Oil’s state-of-the-art facility will only produce 3 crore liters of 2G ethanol.  
    • There are 12 such facilities in various stages of planning and construction. 
  • International Energy Agency suggested that in the last decade, up to 20% of our total primary energy supply was met by biomass, and a large portion of it was used by households. 

Biofuel Targets of India 

  • The government aims to achieve a 20% ethanol blending with petrol (E20) by 2025-26.
  • In India, biofuels are primarily associated with first-generation (1G) ethanol, which is sourced from food crops like sugarcane and foodgrains. 
What is Ethanol-blanded Gasoline

Factors that Derive production of ethanol in India 

  • Demand Enrichment: Governments’ mandate for blending a minimum percentage (%) of ethanol with gasoline fuel & production of ethanol compatible vehicles.
  • Supply Enrichment: Schemes for ethanol production from different feedstocks and encouragement to augment bio-refineries and their capacities.
  • Incentives: Promoting the use of higher ethanol blends through price incentives (tax relief at the retail level) and tax incentives for vehicles compatible with E20 and E85.

Prospects of Biofuel in India 

  • The demand for 20 per cent blending is set to increase India’s ethanol demand to nearly 1,100 crore liters by 2025. 
  • Achieving the 2025 target will require investments, and the ability to provide and divert the necessary feedstock for the domestic production of ethanol. 
  • A NITI Aayog report also indicated a growth in petrol demand by over 45 per cent by 2030, compared to 2021. 
  • The share of four-wheeler is going to increase Nearly 55 per cent of respondents in a 2021 study focused on urban India by the Council on Energy, Environment and Water. 

Challenges to Bio-fuels in India

  • 1G Ethanol Dominance: India primarily relies on first-generation (1G) ethanol, sourced from food crops, particularly sugar cane and foodgrains, to meet its ethanol blending targets.
  • Resource Depletion and Food Security:
    • Growing sugar cane and using foodgrains for ethanol production have significant implications for groundwater depletion and food security.
    • These practices may not be sustainable, given stagnant crop yields, climate change impacts, and limited resources.
  • Groundwater Issue: 
    • Groundwater depletion from sugarcane cultivation and diverting food crops for ethanol production can have negative consequences, especially given stagnant crop yields and the need to feed a growing population.
    • According to the study by University of Michigan rates of groundwater depletion could triple during 2040-81 compared with the current rate.
  • Agriculture's GHG Emissions: Diverting crops towards fuel production increases greenhouse gas (GHG) emissions from the agriculture sector, counteracting the goal of reducing emissions in the transport sector.
  • Greenhouse Gas Emissions: The agriculture sector is noted for its direct greenhouse gas (GHG) emissions, and using it to produce motor fuel may lead to a net increase in emissions, counteracting efforts to reduce emissions from the transport sector.
  • Challenge of Scaling up: Balancing economies of scale with energy needs and costs for biomass collection and transport remains a challenge.

Way Forward

  • Clarity in Definition: The term 'biofuel' encompasses both sustainable and unsustainable fuels. Distinguishing between them is crucial for effective decarbonization efforts.
  • Sustainable Biofuels:
    • Sustainable biofuels, produced from crop residues and other low-impact sources, have a lower water and GHG footprint. 
    • Global Biofuels Alliance initiative aim to develop these sustainable alternatives and promote ethanol use.
  • Biomass Use: The Energy Transitions Commission recommends prioritizing biomass use in sectors where low-carbon alternatives are limited, such as long-haul aviation and road freight, where electrification is challenging.
  • Alternative Strategies: Alternative strategies can be formulated to reduce negative consequences, such as reducing surplus sugarcane cultivation, could be explored to address the issue of surplus sugar production and prioritize food production.
  • Diversification of Fuel Base: Diversifying our fuel base, the primary focus of policy must be to slow down the overall consumption of petrol in the economy and address the private demand for fuel. 

Achieving true sustainability in biofuels is a complex task. Any strategy must be carefully assessed within the larger ecosystem to avoid unintended negative consequences.

Harami Nala: The rogue or treacherous channel Between India and Pakistan

Context: Union home minister visited Harami Nala (rogue or treacherous channel) in the Sir Creek sector of Kutch region of Gujarat, near the India-Pakistan border.

About Harami Nala

  • It is a natural water body, approximately 25 kilometers long, flowing from west to east from Pakistan into Kutch, just south of Vighakot sector. It is flanked by vast marshy mud flats affected by low and high tides.
  • About 22 kilometers of the channel lie on the Indian side of "vertical line" of the International Boundary (IB) between India and Pakistan, which itself is not contested. A portion of Rajasthan's Barmar district also touches this area.
  • It is extremely rich in fishing, especially prawns.
  • The formidable marshy terrain through which it runs makes it impossible to approach or patrol on foot, even during low tide.
  • There are dangerous tides, muddy areas, and mirages, and it also gets extremely hot in the summer, with temperatures exceeding 50 degrees Celsius.
  • It is one of the most inhospitable places along the border and has also been at the center of cross-border mischief and exploitation by infiltrators.
  • The water body has some unique characteristics. Tidal waters surge from the Pakistani side, and over the years, the channel has extended further on the Indian side.
  • On the Pakistani side, there's a wall called Chini-Bandh, built with assistance from China, to prevent ocean water from flooding their side. On the Indian side, there is a significant distance from the IB where factories have emerged to produce salt, bromide, and other chemicals carried by mineral-rich waters.
  • The channel's proximity to the coast and urban centers like Gujarat and Mumbai has made it an attractive route for potential infiltrators.

About Gulf of California

  • Gulf of California  is a large body of water that separates Baja California Peninsula from the Mexican mainland. 
  • It is semi-closed waterbody and its water is protected from cold current of the Pacific.
  • Gulf of Mexico is listed as one of the 66 Large Marine Ecosystems of the World with high endemism.
  • Unique fish species found in Gulf of California are Totoaba (Critically Endangered) and Vaquita Porpoise (Critically Endangered).

Reasons for decline in the population of Vaquita Porpoise

  • Main cause for the decline of population of Vaquita Porpoise is their incidental mortality in gillnets as bycatch. 
  • They are mainly entangled in shrimp gillnets and nets set for totoaba.
  • Totoaba is a fish similar in size to Vaquita. Value of Totoaba has skyrocketed due to demand in black market for totoaba swim bladers in Hong Kong and China. 
  • Vaquita Porpoise has low reproductive rate and limited geographical distribution which makes it high vulnerable to human disturbances.
  • Other reasons include increased urbanisation around Gulf of California and increased pollution

India- Middle East- Europe Economic Corridor

Context: Days after the launch of the India-Middle East-Europe Economic Corridor, Prime Minister Narendra Modi on Monday described Saudi Arabia as “one of the most important strategic partners of India”.

The exchange between the two sides took place during the state visit of Crown Prince Mohammed Bin Salman of Saudi Arabia when they agreed to set up a joint task force to fast-track the West Coast refinery project.

  • Further PM Modi and Prince Bin Salman also co-chaired the first meeting of the India-Saudi Strategic Partnership Council (SPC)
  • The discussion focused on defence, energy, security, education, technology, transportation, healthcare, tourism and culture, space, and semiconductors as areas of possible cooperation.
  • The new thing that has come up is that the two sides agreed to set up a joint task force to help in identifying and channelising the $100 billion investment which was actually promised by the Saudi side. Earlier Crown Prince Bin Salman had visited India in February 2019 when Saudi Arabia had pledged to invest $100 billion and the investment into the energy project.
  • Delhi and Riyadh would upgrade energy ties to “comprehensive energy partnership”

About India-Middle East- Europe Corridor:

  • The project includes India, the UAE, Saudi Arabia, the European Union, France, Italy, Germany and the US.
  • It will be a major medium of economic integration between India, West Asia and Europe and  will give a new direction to connectivity and sustainable development of entire world.
image 49

What is the project?

  • The rail and shipping corridor is part of the Partnership for Global Infrastructure Investment (PGII) — a collaborative effort by G7 nations to fund infrastructure projects in developing nations. PGII is considered to be the bloc’s counter to China’s Belt and Road Initiative.
  • The corridor will include a rail link as well as an electricity cable, a hydrogen pipeline and a high-speed data cable
  • The project is thus duped as “a green and digital bridge across continents and civilizations.”

Why is the project being proposed?

  • First, it would increase prosperity among the countries involved through an increased flow of energy and digital communications. 
  • Second, the project would help deal with the lack of infrastructure needed for growth in lower- and middle-income nations. 
  • Third, it could help “turn the temperature down” on “turbulence and insecurity” coming out of the Middle East
  • Lastly, the project could be seen as Biden’s attempt to further strengthen the G20 group to counter the dominance of China’s Xi Jinping and Russia’s Vladimir Putin.

Miniaturisation: The Future of Space and Nuclear Technology

Context: The Small Nuclear Reactors and Small Satelite Vehicles have increased the presence of private sector in these sectors, which may lead to cost efficient, environmentally sustainable and competitive future technologies.

Nuclear Fusion and Energy 

Nuclear fission is a reaction where the nucleus of an atom splits into two or more smaller nuclei, while releasing energy.

Nuclear Fusion and Energy 
  • For instance, when hit by a neutron, the nucleus of an atom of uranium-235 splits into two smaller nuclei, for example a barium nucleus and a krypton nucleus and two or three neutrons. 
  • These extra neutrons will hit other surrounding uranium-235 atoms, which will also split and generate additional neutrons in a multiplying effect, thus generating a chain reaction in a fraction of a second.
  • Each time the reaction occurs, there is a release of energy in the form of heat and radiation. 
  • The heat can be converted into electricity in a nuclear power plant, similarly to how heat from fossil fuels such as coal, gas and oil is used to generate electricity.

Nuclear Power Plant Working 

  • In a nuclear reactor heat is produced through the chain reaction happening through the fission.
  • The heat warms the reactor’s cooling agent, typically water, to produce steam. 
  • The steam is then channelled to spin turbines, activating an electric generator to create low-carbon electricity.

Small modular reactors (SMRs)

SMRs are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit, which is about one-third of the generating capacity of traditional nuclear power reactors. SMRs, which can produce a large amount of low-carbon electricity, are:

  • Small – physically a fraction of the size of a conventional nuclear power reactor. 
  • Modular – making it possible for systems and components to be factory-assembled and transported as a unit to a location for installation. 
  • Reactors – harnessing nuclear fission to generate heat to produce energy.

Advantages of SMR 

  • Given their smaller footprint, SMRs can be sited on locations not suitable for larger nuclear power plants.
  • refabricated units of SMRs can be manufactured and then shipped and installed on site, making them more affordable to build than large power reactors, which are often custom designed for a particular location, sometimes leading to construction delays.
  • SMRs offer savings in cost and construction time, and they can be deployed incrementally to match increasing energy demand.
  • In areas lacking sufficient lines of transmission and grid capacity such as rural areas, SMRs can be installed into an existing grid or remotely off-grid, as a function of its smaller electrical output, providing low-carbon power for industry and the population.
  • SMRs have reduced fuel requirements. Power plants based on SMRs may require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants
  • In comparison to existing reactors, proposed SMR designs are generally simpler, and the safety concept for SMRs often relies more on passive systems and inherent safety characteristics of the reactor, such as low power and operating pressure.

Moore’s Law

Moore’s Law is a reductive title for the idea, first postulated by American engineer Gordon Moore in the 1960s, that approximately every two years, technology doubles the total number of transistors that manufacturers can squeeze into an integrated circuit. In general terms, it implies that computing power increases exponentially over time.
A simplified definition of Moore’s Law indicates that the speed of individual microchips as well as the overall amount of computing power available doubles around every two years.  

Small Satellite Launch Vehicle

  • Small Satellite Launch Vehicle (SSLV) is the new launch vehicle of ISRO capable of launching Mini, Micro or Nano satellites (10 to 500 kg mass) to 500 km planar orbit. 
  • SSLV is a three-stage vehicle with all solid propulsion stages. 
  • The satellite insertion into the intended orbit is achieved through a liquid propulsion-based Velocity Trimming Module (VTM).

  • It has high flexibility in accommodating multiple satellites.
  • It has launch-on-demand feasibility.
  • It needs minimal launch infrastructure requirements.
  • The advantage of SSLVs is that each rocket can be integrated within as short a span of time as 72 hours, against more than a month taken for other launch vehicles.

What are Picoflare jets?

Context: Researchers studying the findings of the Solar Orbiter Aircraft, a joint mission by the European Space Agency and the U.S. space agency NASA, recently announced that they have detected picoflare jets from the sun’s outer atmosphere.

About Picoflare jets:

  • It is a tiny jet (plasma ejections) of charged particles emanating from the Sun's outer atmosphere.
  • According to the researchers, these charged small particle jets, which are ejected intermittently are a source of the solar wind. This flow is not actually uniform, the ubiquity of the jets suggests that the solar wind from coronal holes might originate as a highly intermittent outflow.
  • These widespread yet faint jets, only a few hundred kilometers across, were seen to last between 20 to 100 seconds, achieving speeds of approximately 100 kilometers per second. Their energy appears to be derived from magnetic reconnection. 
At the Sun's Poles - Picoflare Jets

Significance of Picoflare jets:

  • Due to their relatively low kinetic energies, researchers named these structures picoflare jets. Based on their calculations, they suggest that plasma outflows from these numerous, frequent picoflare jets, channeled along the open magnetic field lines of coronal holes, might supply a considerable amount of mass and energy to the solar wind throughout the solar cycle.
  • It has significant effects on the large-scale solar system as well as on Earth's magnetic field and poses risks to satellite electronics. 

Solar Orbiter Aircraft

  • It is a next-generation solar-observing satellite developed by a collaboration between the European Space Agency (ESA) and NASA.
  • It was launched in 2020.
  • It will provide unprecedented details about the solar system and the images of the sun’s poles while investigating the heliosphere.
  • It is equipped with a suite of scientific instruments to observe the Sun up close and provide new insights into its behaviour, including its magnetic fields, solar wind, and how it influences the solar system.

Solar winds

  • The outermost layer of the Sun's atmosphere, known as the corona, is composed of extremely hot plasma. Some of this plasma escapes the Sun's gravitational pull and flows outward into space, creating the solar wind. 
  • The solar wind is a stream of charged particles, primarily electrons and protons, that constantly blows away from the Sun and interacts with objects in the solar system, including the Earth.

Corona

  • It is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space
  • It is composed of extremely hot and tenuous plasma (ionized gas). 
  • It is visible during a total solar eclipse as a pearly-white halo of light surrounding the dark disk of the Moon. 
  • It is much hotter than the Sun's surface, with temperatures reaching millions of degrees Celsius. 

Nataraja - Lord of Dance and Imperial Cholas

Context: The Nataraja sculpture now on display at Bharat Mandapam, where the G20 Leaders' Summit took place, depicts Lord Shiva in a manner that originated in the fifth century AD but gained iconic status during the reign of the Great Cholas.

More about the news:

  • The 27-foot Nataraja is the world's tallest statue of Lord Shiva in his dancing form.
  • The remarkable sculpture is crafted from an ashtadhatu, an eight-metal alloy, skillfully fashioned by artisans from Swamimalai in the Thanjavur district of Tamil Nadu.
  • Srikanda Sthapathy collaborated with his brothers to create this masterpiece and the design of the statue draws its inspiration from three esteemed Nataraja idols:
    • Thillai Nataraja Temple in Chidambaram
    • Uma Maheswarar Temple in Konerirajapuram
    • Brihadeeswara Temple, an UNESCO World Heritage Site, located in Thanjavur.

The Cholas and the Nataraja Sculpture

  • The Cholas, a prominent dynasty that thrived during the 9th-11th centuries AD, ruled over a significant portion of peninsular India and are closely associated with the development of Nataraja art.
  • The Cholas, devout followers of Shaivism, constructed elaborate Shiva temples throughout their territories, including the iconic one in Thanjavur.
  • K A Nilakanta Sastri, a pioneering historian of South India, highlighted the prevalence of Shaiva figures in Chola sculpture in his book 'The Colas' (1937), stating that while Vaishnava and Jain images were present, Shaiva figures held the most significance.
  • Although the depiction of Shiva as Nataraja dates back to the fifth century AD, it was under the Cholas that this form achieved its present iconic status.
  • Sastri has also noted that Nataraja images, particularly in bronze, were highly regarded among Chola sculptures, and they continue to hold cultural significance to this day.
Nataraja Sculpture

Shiva as the Lord of Dance

  • The worship of Shiva has evolved from the Vedic deity Rudra. Shiva is a multifaceted deity within the Puranic pantheon, characterized by complexity and depth.
  • A L Basham, a prominent Indologist, described Shiva as ‘death and time (Mahakala),’ a deity who both destroys all things and serves as a patron of ascetics in his work 'The Wonder that was India' (1954).
  • Shiva also embodies the persona of the 'Lord of Dance' or Nataraja, credited with inventing a diverse range of dances, from serene and gentle to fierce, orgiastic, and formidable.
    • In the classic portrayal of Nataraja, he is encircled by a flaming aureole or halo, symbolizing the circle of the world that he both encompasses and transcends.
    • His long dreadlocks flow outward, animated by the energy of his dance, and he strikes a rhythmic pose with his four arms.
    • In his upper right hand, he holds a damru (a hand drum), the sound of which draws all beings into his rhythmic motion.
    • In his upper left arm, he holds agni (fire), which he can wield to bring about the destruction of the universe.
    • Beneath one of Nataraja's feet, a dwarf-like figure lies crushed, symbolizing illusion, which misleads humanity.
    • However, amidst the symbolism of destruction, Nataraja also offers reassurance, depicting Shiva as the Protector.
    • With his front right hand, he makes the 'abhayamudra' (a gesture that allays fear), and with his raised feet, he points to his feet, urging his devotees to seek refuge there.
    • Remarkably, Nataraja is often depicted with a broad smile, signifying his simultaneous embrace of both life and death, joy and pain.

The Lost Wax Method (Cire-Perdue)

The ancient technique can be traced back at least 6,000 years, with evidence of its use found in a copper amulet from a neolithic site in Mehrgarh, Balochistan (present-day Pakistan), dating back to circa 4,000 BC.The famous Dancing Girl of Mohenjo Daro was also created using this method. For millennia, the lost-wax method stood as the foremost technique for producing intricate metallic sculptures, and the Cholas elevated this skill to its zenith.A molten metal is poured into a Mold that has been created by means of a wax model. Once the mold is made, the wax model is melted and drained away. A hollow core can be effected by the introduction of a heat-proof core that prevents the molten metal from totally filling the mold. 

Bronze Sculptures during the Chola Period:

  • During the 10th century, evolving religious beliefs required Hindu deities to participate in various public roles akin to human monarchs.
  • Consequently, large bronze sculptures were crafted to be carried outside temples for daily rituals, processions, and festivals.
  • The iconic dancing depiction of Shiva as Nataraja was conceived and fully refined during the Chola Period, leading to the creation of numerous variations of this intricate bronze image. 
  • The region of Thanjavur (Tanjore) in Tamil Nadu played a pivotal role in the evolution of a diverse range of Shiva iconography.
  • An exceptional example from the ninth century is the depiction of the Kalyanasundara murti, which ingeniously portrays the marriage ceremony through two separate statuettes.
    • Shiva, extending his right hand, symbolically accepts Parvati's right hand in this representation, with Parvati displaying a bashful expression as she takes a step forward.
  • The union of Shiva and Parvati is brilliantly captured in a single image through the Ardhanarisvara Murti, where the two halves merge to form a harmonious whole. 
  • Independent figurines of Parvati have also been sculpted with grace, portraying her in the elegant tribhanga posture.
  • Bronze sculptures during the Chola period were meticulously crafted using the artistic technique known as Cire Perdue or Madhu Uchchishtta Vidhana, also called lost-wax casting.
    • The method involved mixing beeswax, a type of camphor called kungilium, and a small amount of oil, kneading this mixture, and using it to sculpt the figure and its intricate details.
    • The wax model was then coated with clay, dried, and placed in an oven to melt or evaporate the wax.
    • Subsequently, Pancha Loham, a bronze alloy, was melted and poured into the clay mold, filling every crevice and detail.
    • After cooling and solidifying, the clay mold was broken, leaving only the bronze sculpture.
    • The final steps included adding finer details, cleaning, removing any blemishes, and smoothing and polishing the sculpture before it was displayed, typically within a temple.

Hybrid Nanoparticles to target Cancer cells

Context: Scientists at the Indian Institute of Science (IISc) have developed a new approach using hybrid nanoparticles to potentially detect and kill cancer cells, especially those which form a solid tumour mass. The researchers have tested the nanoparticles on lung cancer and cervical cancer cell lines in the lab. They now plan to take the results forward for clinical development.

About Hybrid nanoparticles:

  • The IISc team created hybrid nanoparticles by combining gold and copper sulphide nanoparticles. They used a novel reduction method to deposit tiny seeds of gold onto the copper sulphide surface. The resulting hybrid nanoparticles are less than 8 nm in size.
    • Copper sulphide nanoparticles have previously received attention for their application in cancer diagnosis.
    • Gold nanoparticles can be chemically modified to target cancer cells and have shown anticancer effects.
  • These particles have photothermal, oxidative stress, and photoacoustic properties, the properties can be utilised to kill cancer cells using heat and enable their detection using sound waves.
    • Photothermal property: When light is shined on these hybrid nanoparticles, they absorb the light and generate heat, which can kill cancer cells.
    • Oxidative stress: These nanoparticles produce singlet oxygen atoms that are toxic to the cancer cells.
    • Photoacoustic property: The photoacoustic property of the nanoparticles allows them to absorb light and generate ultrasound waves, which can be used to detect cancer cells with high contrast once the particles reach them.
      • Ultrasound waves generated from the particles allow for a more accurate image resolution as sound waves scatter less when they pass through tissues compared to light.
      • Scans created from the generated ultrasound waves can also provide better clarity and can be used to measure the oxygen saturation in the tumour, boosting their detection.

Advantages:

  • The small hybrid nanoparticles can potentially travel inside tissues easily and reach tumours. Further, it is believed that their small size would also allow them to leave the human body naturally without accumulating.
  • The hybrid nanoparticle system can be integrated with existing systems of detection or treatment. For example, the nanoparticles can be triggered to produce heat by shining a light on them using an endoscope that is typically used for cancer screening.

  • Parliamentary Committees: Parliamentary committees complement the work of Parliament by scrutinizing bills, budgetary proposals, and government ministries in detail. They play a crucial role in oversight and ensuring the efficiency of government operations.

Role of Member of Parliament (MP) 

  • Legal Obligation: MPs in India seek endorsement every 5 years for their plans and programs from their constituents through free, fair, and open elections. This underscores the democratic principle that MPs derive their authority from the people they represent.
  • Constitutional and Moral Authority: MPs are bestowed with both constitutional and moral authority. They have the authority to enact laws, set political goals, allocate resources, and hold the executive accountable for its actions.
  • Voice of the Common Citizens: MPs serve as the voice of the common citizens, bridging the gap between the government and the people.
    • They are responsible for bringing the concerns, issues, and difficulties of their constituents to the attention of the government and the nation.
  • Executive Accountability: MPs play a crucial role in securing accountability of the executive branch of government.
    • They have instruments at their disposal, such as the Constitution, Rules of Procedure, and precedents, to hold the government accountable for its acts and decisions.
  • Parliamentary Privileges: The Constitution grants MPs certain rights, privileges, and immunities to enable them to discharge their responsibilities efficiently and effectively.
    • These privileges protect the autonomy, authority, and dignity of Parliament from interference by other branches of the state.
  • Responsibility to Uphold Dignity: MPs are morally bound to speak responsibly in Parliament and adhere to the highest parliamentary norms. Their dignified and decorous behavior is expected as they are looked upon as role models.
  • Respect for Democratic Values: MPs collectively contribute to creating a vibrant and living embodiment of the will of the people.
    • They respect and uphold constitutional values, the unity of the nation, and the common good while accommodating all shades of opinion.

Issues in the Functioning of Indian Parliament 

  • Disruptions and Unruly Behavior: The disruptions have become increasingly common and have resulted in lower productivity of the House which hinders meaningful deliberation and debate on national issues.
  • Decline in Parliamentary Norms: Members are morally bound to speak responsibly, but there have been instances of frivolous, baseless, and defamatory allegations resulting in a decline in parliamentary norms.
  • Lack of Informed Debate: Disruptions have led to the passing of important legislation without detailed debates.
    • This means that critical issues may not receive the thorough discussion they deserve, which is essential for well-informed decision-making.
  • Obstructionism: While the right to question and dissent is integral to democracy, obstructionism has become a problem. Some members use disruption to express disapproval rather than engaging in informed debate, wit, and humor.

Use of technology in Parliament  

  • Digital Sansad App: The Digital Sansad app has been developed and continuously improved to enhance communication and engagement between members of Parliament, legislative bodies, and citizens.
    • This app provides access to parliamentary proceedings, documents, and updates.
