The third edition of the popular exam for admission into engineering, architecture and planning courses at the graduation level will be conducted between 20 to 25 July as per the new schedule.

JEE Mains 2021

As the exam is to be conducted from 20 to 25 July, and as per the usual trend, the admit card would be made available for the download just about 10 or 15 days before the exam.

Students should regularly visit the official website for the exam ‘https://jeemain.nta.nic.in/webinfo2021/Page/Page?PageId=1&LangId=P’

Downloading the hall ticket for JEE Mains 2021 third edition is a simple process for the candidates.

They have to visit the official website mentioned above and click the link for downloading their hall ticket.

Soon after when another webpage downloads, students have to enter their username and password which they have created during the registration process and login.

Post login, they can view the admit card and download it and take a printout of it.

Before the applicants go for a printout, they have to check the admit card for any mistakes with regards to their name, date of birth, exam centre or any other important information.

Should they find a mistake, they have to take it to the notice of authorities concerned for suitable rectification.

If there are no mistakes on the hall ticket, students can download it and take a printout of it.

It is interesting to note that JEE Mains exam which was usually held for two times a year till recently will now be held for four times a year starting from 2021.

This year onwards JEE Mains was to he held in February, March, April and May. The first two editions of JEE Mains 2021 were successfully conducted.

The outbreak of COVID-19 for the second time in India led to postponement of April and May editions of JEE Mains 2021.

Applicants can register for the fourth edition of JEE Mains 2021 from 9 to 12 July. The fourth edition of JEE Mains 2021 would be held from 27 July to 2 August.

The dates for downloading of hall ticket and declaration of results for both the editions will be announced later, according to a notification released by National Testing Agency (NTA).

NTA is the agency that conducts the exam. However, as far as the fourth edition of JEE Mains is concerned, the hall ticket would likely be released by around 18 to 20 July as per the actual trend.

The actual trend is to release the hall ticket for download about 10 to 15 days before the commencement of the exam.

Applicants should remember that the above mentioned dates are just an estimation taking to account the prevailing usual trends.

The exact details will be available on the official website of JEE Mains 2021 which has been already mentioned above.

There is another important point attached to JEE Mains 2021.

Candidates who have already applied for April and May editions of the exams could take up corrections with regards to details provided in the application forms.

The corrections were allowed from 6 to 8 July for April session of JEE Mains 2021. Similarly, applicants for May editions of JEE Mains 2021 are allowed to make corrections from 9 to 12 July.

What are the fields in which applicants can make corrections? The corrections can be takenup with regards to Session, Category, Subject etc.

JEE Mains 2021 holds a great significance for those who want to do engineering or architecture in IITs.

There is another point to remember. The third edition of JEE Mains 2021 (April) will be held only for Paper 1 (BE/BTech).

Candidates have to appear for JEE-2021 and have to get a score that puts them among the top 2.5 lakh rank holders if they are to apply for JEE Advanced a pass in which gets admission in IITs.

Designed to monitor the freshness of seafood in real-time by responding to pH changes, the film offers a practical solution for improving food safety and reducing waste.

This film detects the release of volatile amines, compounds typically associated with spoilage, and indicates food quality through visible color changes, say sources from NIT Rourkela.

These natural components make the film biodegradable, safe, and responsive, aligning with sustainability goals and offering a non-invasive way to assess seafood freshness.

Findings

The findings of this research have been published in the journal Food Packaging and Shelf Life in a paper co-authored by Prof. Preetam Sarkar (as the lead corresponding author), along with his research scholars, Mr. Rahul Thakur, Miss Harshi Singhi, Mr. Vedsagar Rajesh Suryavanshi, and Dr. Ravichandran Santhosh.

Other co-authors in this work include Dr. Khalid Gul from NIT Rourkela, Dr. Swarup Roy from Lovely Professional University, Dr. Srinivas Janaswamy from South Dakota State University, Brookings, USA and Dr. Kirtiraj K. Gaikwad from IIT Roorkee.

Fishing

India is the world’s second-largest fish-producing nation, contributing approximately 8% of global fish production, say NIT Rourkela researchers.

It also holds the distinction of being the top five producer of shrimp globally, with frozen shrimp being the top export commodity.

Given the scale and importance of seafood production, innovations that ensure freshness and reduce spoilage are of immense value, say NIT Rourkela researchers.

In this context, intelligent packaging systems, which preserve food while monitoring its quality, are rapidly gaining global interest.

Unlike conventional packaging that serves merely as a protective barrier, the intelligent packaging film developed by NIT Rourkela team offers visual cues about the product’s condition, making it a promising solution for enhancing food safety and reducing waste.

The beetroot peel extract was prepared separately, and then combined with the starch, gum tragacanth, and a small amount of glycerol to cast the films.

These were dried and tested for their pH-sensitivity and effectiveness in monitoring seafood freshness, said Prof Preetam of NIT Rourkela.

Pigments

Beetroot peels contain betalains, a group of pigments known for their bright colours and pH sensitivity, say NIT Rourkela researchers.

These pigments also offer antioxidant and antimicrobial benefits, making them suitable for food-related applications.

Incorporating these natural compounds into the starch-based film creates a biodegradable, safe, and responsive packaging material.

When the seafood begins to spoil and pH levels rise, the film changes colour, providing a clear visual indicator of freshness.

Starch

The choice of Kodo millet starch and gum tragacanth contributes to the film’s biodegradable and eco-friendly profile.

Kodo millet is an underutilised grain with excellent film-forming properties, while gum tragacanth enhances the mechanical strength and flexibility of the material.

The researchers believe that using such agricultural by-products not only supports sustainability but also adds value to food processing waste, such as beetroot peels.

At the laboratory scale, the cost of producing the film was estimated approximately Rs. 900 per kilogram.

When scaled up for industrial production, the cost is projected to range between Rs. 400 and Rs. 600 per kilogram, making it a potentially viable option for commercial use.
