Mother of thousands Plant (Kalanchoe daigremontiana): Introduction Classification, Distribution, Description, Chemical constituents, and, Care

The succulent plant Kalanchoe daigremontiana, also known as The Mother of thousands, Alligator plant, Devil’s backbone, the Crown of thorns, or Mexican hat plant, is indigenous to Madagascar. It was formerly known as Bryophyllum daigremontianum. It can reproduce vegetatively through plantlets that form on its leaf margins, as well as by upshoots from lateral roots, seeds, and other Bryophyllum species (now included in the genus Kalanchoe).

Lumpy Skin Disease: Introduction, History, Geographic distribution Epidemiology, Causative Agent, Susceptible Hosts, Transmission, Treatment, Control, and prevention

The disease is most likely spread by biting flies and a few species of ticks, and these vectors are difficult to quarantine and regulate movement against. Control in endemic areas must therefore be limited to immunoprophylaxis. LSD vaccination has been done in two different ways. The vaccine virus is now grown in cell culture, but the Neethling strain of LSD was attenuated in South Africa by 20 passes on the chorio-allantoic membranes of hens’ eggs.
In Kenya, cattle receive strong protection against LSD via vaccination made from sheep or goat pox viruses. Because the vaccine could otherwise serve as a source of infection for the susceptible sheep and goat populations, this vaccine has the drawback that it can only be used in nations where sheep pox or goat pox is endemic. To establish an appropriate defense against LSD, susceptible adult cattle should receive a vaccination every year. At the site of inoculation, about 50% of cattle experience swelling that is 10–20 mm in diameter; in dairy cows, this swelling may be accompanied by a brief decrease in milk production. Within a few weeks, the swelling goes away. To avoid interference from the maternal antibody, calves under 6 months old whose moms were either naturally infected or inoculated shouldn’t receive the vaccine. To stop epidemics, calves from sensitive cows should be immunized because they are more susceptible.

TEACHER’S DAY: History, Date, Significance, and 2022 Theme

To celebrate the birth anniversary of Dr. Sarvepalli Radhakrishnan, Teachers’ Day is celebrated throughout India on September 5. He was a well-known academic, the first Vice-President and second President of independent India, and he was awarded the Bharat Ratna. His birthday is September 5, 1888. As an educator, he promoted enlightenment and was a renowned diplomat, academician, and most importantly, a fantastic teacher.
According to a proverb, a nation’s youngsters hold the key to its future, and teachers, in their capacity as mentors, can shape their charges into future leaders who will determine India’s course. They are essential to our lives because they help us succeed financially and professionally. They help us become better individuals, contributors to society, and ambassadors for our country. To recognise the difficulties, challenges, and unique responsibilities that teachers play in our lives, we commemorate Teacher’s Day.
On September 5th, India celebrates Teachers’ Day. Guru Purnima, an additional day in India honouring teachers, was observed on July 13, 2022, this year. The purpose of this holiday is to recognise the influence and contribution of teachers in the lives of their students. Teachers are just as important in a student’s life as parents and other adults because they are charged with teaching them academics as well as morals and values. The most significant and, in some cases, the very first role models or sources of inspiration in their lives are their instructors. This emphasises how significant it is to observe Teacher’s Day. In India, the teacher-student connection has also been exceedingly reverent and respectful since ancient times, which enhances the festivities even more.

Few seeds will float in the water, and the majority of the seeds will settle at the bottom of the bucket. Seeds with damage become hollow and lighter as a result. They float on water as a result.
Seed Drill
In modern times, tractors’ hoes are utilized to spread seeds. This device evenly distributes the seeds at the correct depths.
