Atmospheric Fungi

Atmospheric fungi are microscopic spores and cellular fragments suspended in the air.  Emitted from soil, decaying vegetation, and agricultural operations they act as massive organic aerosols.  They influence regional weather by triggering cloud formation, but can pose significant respiratory and allergic problems to human health.

Ecological and atmospheric roles:-

• Cloud Nucleation: Fungal spores act as highly efficient condensation and ice nuclie.  Water vapour in the atmosphere freezes or condenses around them, driving the hydrological cycle and precipitation patterns.

• Organic Aerosols:  Fungi comprises a staggering around 23 percent of total organic Aerosols emitted into the earth's atmosphere.

Environmental and climate impact:

Fungi spores act as highly effective cloud condensation nuclei (CCN) and ice nuclie (IN).  They actively trigger water droplets and ice crystals to form, significantly influencing precipitation patterns.

Fungi spores are released into the air from soil, decomposing plants, and water, constituting a massive 23% primary organic aerosols, which drives nutrient cycling.

There are hundreds of species of airborne fungi.  Due to lightweight they can travel thousands of kilometres across the globe on wind currents.

Breathing high concentration of fungi spores can cause respiratory ailments like allergy and asthma.

Thousand & One Nights: 72nd Night contd.The Story of Two Viziers

The province of Egypt. Once, here lived a king. He was kind, generous, trusted, courageous and just. He associated himself with learned. He was sympathetic to poor.

Thousand & One Nights: 70th Night

Harun al Rashid on his roaming the country side, saw a fisherman who did not have any catch for the day and worried about his family's bread. The Caliph had brought him to the banks of Tigris and asked him to throw the net. When they pulled the net the catch was a locked heavy chest. The Caliph paid him one hundred dinars. The chest was taken to the palace. Now the story to continue: When the chest was opened there was a girl. She had been cut into nineteen pieces. The Caliph looked at her, felt very sad, and turned to Ja'far and said angrily, "You, dog of a vizier, people are being killed and thrown into river in my city while I take the responsibility of Doomsday. If you do not find her killer, I will hang you and forty of your kin with you." "O Commander of the Faithful, give me three days."Ja'far said. Ja'far went into the city, vexed, worried and sad. He had no idea what to do. He thought to himself, "Where shall I find the murderer?" ...

Thousand & One Nights: 72nd Night

When the story was completed by the young man the king was astonished. "By God, I will hang none," said the king. But he had already decided to find out the slave who played trick on the young man. He said to Ja'far, "Go to the city and bring the slave, or I will strike your neck." Ja'far left in tears in search of the slave. How could he identify the slave who snatched the apple from the young man's son. He thought, "There is no escape from death this time, for the jar cannot be saved everytime. All powerful and omnipotent God who saved me always save me again. By God, I will stay home for three days until God's will is accomplished. He stayed home for two days, and for the third day, by noon, giving himself up for lost, Ja'far summoned the judges and witnesses, and made his will. Then he called his children to him, bade them farewell, and wept. Soon a messenger from the Caliph arrived. He informed that the Caliph was in great rage and swor...
