Solar eclipse to occur on 3rd November

THE Director-General of National Biotechnical Development Agency (NASRDA), Dr Saidu Mohammed, has said the solar eclipse, which will occur on November 3, will come with mild darkness across the 36 states of the federation.

The Director-General, who made this known during a press briefing, last Thursday in Abuja, also advised Nigerians to remain calm, as the eclipse would not affect satellite communications or air services.

The eclipse, however, will be characterised by a flush of sunlight and mild darkness during its peak. The agency has, therefore, made available at its headquarters, sunglasses, which will serve as filters for the effect of the sun.

Dr Mohammed added that: “It will be like any other day, but its effect will be felt at its peak. It is recommended you wear sunglasses. There is no need to panic,” he concluded.

Earlier in his presentation, the Director of Centre for Astronomy, University of Nsukka, Professor Felix Okpara, who outlined the various times of the eclipse across the nation said, in Abuja, the eclipse will begin by 1:03 p.m. It will be at its maximum by 2.40 p.m and it will end by 4.03 p m in the evening. In Lagos, it will begin by 12.50 p.m, its maximum level will take place by 2.40 p.m and end by 4.01p.m.

In Ibadan, the eclipse will start by 12.52 p.m, the maximum level will be witnessed by 2.32 p.m and it will end 4.01 p.m. In Port Harcourt, the eclipse will begin by 1.03 p.m, its maximum will be experienced by 2.43 p.m and by 4.09 p.m, it will end. In Uyo, the eclipse will begin by 1.06 p.m, its maximum will be experienced by 2.45 p.m and by 4.10 p.m, it will end.

In Enugu, the eclipse will begin by 1.04 p.m, its maximum will be experienced by 2.43 p.m and by 4.07 p.m, it will end and in Kano, the eclipse will begin by 1.07 p.m, its maximum will be experienced by 2.40 p.m and by 4.01 p.m, it will end.

An eclipse is an astronomical event that occurs when an astronomical object/objects is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer as seen from the earth.

Solar eclipse was previously recorded in Nigeria concurrently in 1945, 1959, 2001 and 2006.

Chewing stick is better than toothbrush- Dentist

The Head of Dental Department at the State Specialist Hospital, Okitipupa in Ondo State, Dr Segun Adegoke, has said that chewing sticks are better for cleaning the teeth than tooth brush.

Adegoke said that chewing sticks contained anti-microbacterial substance called ‘tannin’ which was the same as fluoride in toothpastes.

He said the natural ‘tannin’ helped to fight bacteria in the mouth, maintained the gums, made the teeth stronger and improved the oral hygiene more than tooth brushes.

“Our aged parents use chewing sticks and even at 60 years of age, their teeth are stronger than that of the youth of today,” he said. “Why many people choose tooth brush is because it is faster to use and they also hold the belief that chewing stick is outdated.

I think chewing sticks are better than tooth brushes because the tannin in it helps in various ways to keep the teeth cleaner, fresher and stronger.”

He, however, said that the only advantage tooth brush had over chewing stick was its ability to get to the corners of the mouth
