WhatsApp Groups Allow Students to Express Themselves Better, Says Study

WhatsApp chat groups help teenagers communicate with their peers and express themselves better compared to classrooms they are part of, a new study claims. The findings of the study say students in WhatsApp groups are able to develop closer and more open relationships with their classmates because of the freedom of expression they enjoy on the platform.

As part of the study, the researchers observed two groups of eight youths aged 16-17, and two groups of eight youths aged 14 to 15. The teenagers perceived WhatsApp chat group as a space that breaks down the hierarchical division created at school.

“The group chats are based on trust among the members of the group, and this enhances the possibility to be in contact,” Arie Kizel from University of Haifa in Israel, was quoted as saying to nocamels.com – an Israeli Innovation news website on Sunday.

WhatsApp Groups Allow Students to Express Themselves Better, Says Study“The discussions on Whatsapp enable the development of a social environment that is warm and human,” Kizel added.

One student described WhatsApp as “a place where there is respect for language and where all those involved share common terms and signs.”
“On WhatsApp, I usually feel that I am not being judged, particularly because there isn’t any eye contact or physical contact, only words and signs. So I feel more intimacy and security,” explained another participant.

The school domain often divides the class into fixed groups and friendships, created on the basis of socioeconomic status, common activities or study tracks, and so forth.

However, the WhatsApp groups break down these divisions and make the class a single, homogeneous group.

“In the WhatsApp group, everyone can talk to everyone else. WhatsApp breaks down the walls we put up between us in class. The WhatsApp group is like a class team-building day,” one participant commented.

New Nano-Film Could Help Developer Better Wearable Devices: Study

New Nano-Film Could Help Developer Better Wearable Devices: StudyNano material researchers from the University of Illinois at Chicago (UIC) and Korea University have invented a cheap ultra-thin film that is both transparent and highly conductive to electric current, offering promise for bendable, wearable electronic devices like smart watches.
The film a mat of tangled nanofibre is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

“It is difficult to make materials that are both transparent and conductive,” said Alexander Yarin, distinguished professor of mechanical engineering at UIC.

The new film establishes a “world-record combination of high transparency and low electrical resistance, the latter at least 10-fold greater than the previous existing record,” informed Sam Yoon, professor of mechanical engineering at Korea University.

The film also retains its properties after repeated cycles of severe stretching or bending an important property for touchscreens or wearables.

The manufacturing begins by electrospinning a nanofibre mat of polyacrylonitrile or PAN, whose fibres are about one-hundredth the diameter of a human hair.
The fibre shoots out like a rapidly coiling noodle, which when deposited onto a surface intersects itself a million times.

The fibre is then electroplated with copper or silver, nickel or gold.

The electrospinning and electroplating are both relatively high-throughput, commercially viable processes that take only a few seconds each, according to the researchers.

“We can then take the metal-plated fibres and transfer to any surface the skin of the hand, a leaf, or glass,” Yarin added in a paper reported in the journal Advanced Materials..

An additional application may be as a nano-textured surface that dramatically increases cooling efficiency, he noted.

Delhi University UG Admission 2017: 5 Points To Remember In Online Registration

Delhi University UG Admission 2017: 5 Points To Remember In Online RegistrationThe undergraduate online registration in Delhi University will kick off tomorrow. The university will be accepting the online registration forms for its 60 undergraduate (UG) programmes in 62 colleges affiliated with the university with around 54,000 seats. The registration will take place between May 22 and June 12. To make the online registration process simple, here we are listing out some important points to keep in mind while applying for the UG courses of University of Delhi.

DU UG Admission 2017: Dates of online registration

The online registration will start from tomorrow, ie, May 22. The last date for the registration will be June 12. The registration for the entrance based courses will start from May 31. According to the university officials, the first cut-off list will be announced on June 20. The university will notify the subsequent cut-off list’ dates soon

DU UG Admission 2017: Documents needed for online registration

Some of the mandatory uploads that an applicant has to make during online registration include passport size photograph, scanned signature, class X board certificate, among others. The University of Delhi will keep the window open for the entire May 12 – June 12 period, so that, the students whose class 12 results are yet to be announced may add their details the results come out, including the CBSE.

DU UG Admission 2017: Online Registration Fee, Multiple programmes

All applicants have to make an online registration fee depending on the categories they belong. There won’t be any extra fee for the multiple programmes from various colleges applicants chose to apply.
“The students can apply for multiple programmes without paying an extra fee,” said a release from the university.

DU UG Admission 2017: Merit Based Courses, Entrance Based Courses

Merit-based courses are those under graduate courses in which admission is done on the basis of marks scored by a student in class 12 board exam. For these courses, the university publishes cut off marks for the various colleges which fall under the aegis of Delhi University.

These are the courses, for which Delhi University conducts an entrance test to select students for admission. The registration for these courses will start from May 31.

Glaucoma treatment developed here more effective, less painful

Image result for Glaucoma treatment developed here more effective, less painfulA laser treatment developed here for glaucoma patients has proven more effective while causing less pain and side effects, according to data from the National University Hospital (NUH).

The treatment – micropulse transscleral cyclophototherapy (MPTCP) – involves shooting small lasers into the patient’s eyes, as opposed to the conventional treatment of transscleral cyclophotocoagulation (TCP), which uses a high-intensity laser.

Since last year, 300 patients have successfully undergone the treatment at NUH Eye Surgery Centre.

Within 12 months, 75 per cent of patients who underwent MPTCP had their eye pressure reduced, compared with 20 per cent for the conventional treatment, according to figures NUH released yesterday.

While 30 to 40 per cent of patients who undergo TCP suffer side effects such as inflammation and shrinkage of the eye, there were almost no side effects reported by patients who received the new treatment. It takes 100 seconds to complete, half the time needed for conventional laser treatment.

The latest treatment was developed by Associate Professor Paul Chew, a senior consultant with NUH’s department of ophthalmology, and patented in 2015.

It has been used on 45,000 patients in other countries, such as the United States and the Philippines, over the last two years.

Prof Chew said in a statement: “Patients with advanced glaucoma can now look forward to a treatment which enhances their quality of life.”

Glaucoma results in gradual loss of one’s vision and can lead to blindness. It is caused by improper drainage of fluid from the eye, causing increasing eye pressure that damages the optic nerve.

While glaucoma is incurable, it can be delayed through eye drops and oral medication. In advanced stages of glaucoma, laser treatment is recommended only after invasive surgery fails to reduce eye pressure.

Three per cent of Singapore residents aged 50 and above have glaucoma, rising to 10 per cent for those aged 70 and above.

The maximum temperature of the laser in the new treatment is 35 deg C, compared with 550 deg C in the conventional treatment. This prevents the pain that is commonly reported by patients who have undergone TCP, Prof Chew said.

Retiree Chee Chean Shyong, 64, underwent MPTCP last month, after discovering the glaucoma in his left eye had worsened in March.

“The only pain was when they did the injection for the painkiller into my eye,” said Mr Chee, whose condition has improved.
