Rhodium helpful in checking food adulteration

By changing its colour in the presence of particular gases, Rhodium can warn consumers if packaged food has been tampered with.

This finding could potentially influence the production of both industrial and commercial air quality sensors.

We initially found out by accident that modified rhodium reacts in a colourful way to different gases, says Cathleen Crudden, chemistry professor at Queens Univeristy, Ontario. That happy accident has become a driving force in our work with rhodium.

Rhodium that is modified using carbon, nitrogen or hydrogen-based complexes changes to yellow in the presence of nitrogen, deep blue in the presence of oxygen, and brown in the presence of carbon monoxide, according to a Queens statement.

Explain Axis in Eyeglasses

When you get a prescription for eyeglasses, you will see a chart where the optometrist will write numbers for your prescription. These numbers represent nearsightedness or farsightedness, cylinder and axis. Cylinder and axis are the numbers that refer to astigmatism and how it affects the focal points in a person’s field of vision.

    • The human eye is a sphere. Light enters it and refracts evenly.

Working mums do no harm to their young kids

Here’s some positive news for mothers who are struggling to combine job with bringing up their children.

A new study has found that mothers who go back to work after having a baby do not harm their child’s development.

The long-term study of almost 13,000 UK boys and girls found no evidence that young children suffered by not having a mother who stayed at home.

The researchers found the ideal was for children to have both parents living at home and both working.

The findings will be a relief to the 29 percent of mothers who work full time, as previous research suggested children of working mothers were at risk of developing behavioural problems, reports The Daily Express.

However boys’ behaviour suffered if the mother was the main breadwinner, though girls reacted well to having a working mother.

“Some studies have suggested whether or not mothers work in the first year of a child’s life can be particularly important for later outcomes,” said Dr Anne McMunn, whose study was funded by the Economic and Social Research Council.

“In this study we did not see any evidence for a longer-term detrimental influence on child behaviour of mothers working during the child’s first year of life,” she added.

The researchers found the role model of a working mother improved the behaviour of girls, while a working father improved boys’ behaviour.

They also found that both boys and girls were likely to do better if both their parents were going out to work.

The study also found that five-year-olds living in a single-mother household or living with two parents who did not work were much more likely to have behavioural problems than children where both parents were working.

How to Train for Five Kilometers

Improve your fitness and embark on a challenge to complete a 5K running event. A 5K race has a distance of 5 kilometers or 3.1 miles. Running can be a strenuous activity because it puts a lot of impact on your body as you pound on the ground. It’s important to increase distance and speed gradually so that you can avoid injuries and knee, ankle and joint pains.

Difficulty: Moderate
    • 1

      Start a seven to nine-week training program before a 5K event to gradually improve your fitness level and endurance.
