Sameera Moussa

Sameera Moussa () (March 3, 1917 – August 5, 1952) was the first female Egyptian nuclear physicist. Sameera held a doctorate in atomic radiation. She hoped her work would one day lead to affordable medical treatments and the peaceful use of atomic energy. She organized the Atomic Energy for Peace Conference and sponsored a call that set an international conference under the banner "Atoms for Peace." She was the first woman to work at Cairo University.
Youth and college.
Moussa was born in Egypt in Gharbia Governorate in 1917. Her mother died from cancer, and her father was a famous political activist. He moved with his daughter to Cairo and invested his money in a small hotel in the El-Hussein region. At the insistence of her father, Moussa attended Kaser El-Shok primary school, one of the oldest schools in Cairo. After she completed her primary education, she joined the Banat El-Ashraf school, which was built and managed by her father.
Despite the fact that Moussa achieved high grades in her secondary education, and could have pursued a career in engineering, she insisted on joining the Faculty of Sciences at Cairo University. In 1939, Moussa obtained a BSc in radiology with first class honors after researching the effects of X-ray radiation on various materials. Dr. Moustafa Mousharafa, the first dean of the faculty, believed in his student enough to help her become a remarkable lecturer at the faculty. Afterwards, she became the first assistant professor at the same faculty and the first woman to hold a university post, being the first to obtain a PhD in atomic radiation.
Nuclear research.
Moussa believed in Atoms for Peace. She was known to say "My wish is for nuclear treatment of cancer to be as available and as cheap as Aspirin". She worked hard for this purpose and throughout her intensive research, she came up with a historic equation that would help break the atoms of cheap metals such as copper, paving the way for a cheap nuclear bomb.
Moussa organized the Atomic Energy for Peace Conference and sponsored a call for setting an international conference under the banner "Atom for Peace", where many prominent scientists were invited. The conference made a number of recommendations for setting up a committee to protect against nuclear hazards, for which she strongly advocated. Moussa also volunteered to help treat cancer patients at various hospitals especially since her mother went through a fierce battle against this disease.

Omegatetravirus

Omegatetravirus is a genus of viruses, in the family "Alphatetraviridae". Moths and butterflies serve as natural hosts. There are three species in this genus. Infection outcome varies from unapparent to lethal.
Taxonomy.
The following species are assigned to the genus:
Structure.
Viruses in "Omegatetravirus" are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and bipartite, around 2.5kb in length.
Life cycle.
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by leaky scanning. Moths and butterflies serve as the natural host. Transmission routes are oral.
