What’s best fabric combos for cloth masks

15

Sydney, June 24 | During the Covid-19 pandemic, cloth face masks became a way to help protect from the virus. For some people, they became a fashion statement, with many fabric choices available. But just how effective are they, especially in blocking respiratory droplets from a sneeze?

Researchers from the University of New South Wales used high-speed videos of a person sneezing to identify the optimal cloth mask design.

The team made simple face masks with 17 commonly available fabrics. Each mask had one, two or three layers of the same or different fabrics.

A healthy 30-year-old volunteer donned each mask, tickled the inside of his nose with tissue paper on a cotton swab, and then readjusted the mask just before the onset of a sneeze.

The researchers captured high-speed videos of the sneezes and computed the intensity of droplets in the images in a region 2 cm from his mouth. With each fabric layer, the droplet-blocking capability improved by more than 20-fold.

Interestingly, all of the three-layer cloth combinations the researchers tested were more effective than a three-layer surgical mask.

The best masks for blocking droplets contained a hydrophilic inner layer of cotton or linen, an absorbent middle layer of a cotton/polyester blend and a hydrophobic outer layer of polyester or nylon. The findings are detailed in the journal ACS Biomaterials Science & Engineering.

Machine washing the masks didn’t decrease their performance; in fact, masks containing cotton or polyester worked slightly better after washing because of pore shrinkage. Future studies are planned with more people and different age groups, said researchers including Shovon Bhattacharjee, from the UNSW.

Face masks help reduce disease spread by blocking tiny, virus-laden droplets expelled through the nose and mouth when a person speaks, coughs or sneezes.

Does MBA really help in getting a better job offer ?

Does MBA really help in getting a better job offer ?

Most students pursuing an MBA come with the sole objective of having a decent job offer or a promotion in the existing job soon after completion of the MBA. And most of them take loans to pursue this career dream. According to a recent survey by education portal Campusutra.com  74% MBA 2022-24 aspirants said they would opt for education loans.

There are exceptional cases like those seeking master’s degree or may have a family business to take care of or an entrepreneurial venture in mind. But the exception cases are barely 1%. For the rest 99%, a management degree is a ticket to a dream job through campus placements or leap towards career enhancements. Stakes are high as many of them quit their jobs which essentially means loss of 2 years of income, apprehension and uncertainty of the job market. On top of that, the pressure to pay back the education loans. Hence the returns have to be high. There is more than just the management degree. Colleges need to ensure that they offer quality management education which enables them to be prepared for not just the demands of recruiters and for a decent job but also to sustain and achieve, all along their career path.

  • So, what exactly are the B Schools doing to prepare their students for the job market and make them industry ready ?
  •  Are B schools ready to deliver and prepare the future business leaders to cope up with the disrupted market ?  

These are the two key questions every MBA aspirant needs to ask, check and validate before filling the MBA application forms of management institutes. And worth mentioning that these application forms do not come cheap. An MBA aspirant who may have shortlisted 5 B Schools to apply for, may end up spending Rs 10,000.00 to Rs 15,000.00 just buying MBA / PGDM application forms.

While internship and placements data of some management institutes clearly indicates that recruiters today have specific demands. The skill sets looked for are job centric and industry oriented. MBA schools which have adopted new models of delivery and technology, redesigned their courses, built an effective evaluation process and prepared the students to cope with the dynamic business scenario, have done great with campus placements despite the economic slow down.

However, the skill set being looked for by a consulting company like Deloitte or KPMG may be quite different from FMCG or a manufacturing sector. Institutes need to acknowledge this fact and act accordingly.

  • Management institutes should ensure that students are intellectually engaged, self motivated and adapt to changes fast. In one word ‘VUCA ready’.
  • B Schools should encourage students to participate in national and international competitive events, simulations of business scenarios.
  • Institutes should have the right mix of faculty members with industry exposure and pure academics.

The placement records of 2021 across top management institutes indicated the fact that recruitment is happening, skilled talent is in demand and certain management institutions continued to attract recruiters even in the middle of an ongoing crisis.

It is time, all management institutes rise to the occasion, understand market realities and identify areas of improvement at both ends – students and faculty.

After all, the stakes are high at both ends. B Schools taking corrective measures will stay while those which are lagging will end up shutting down.
