Molecular Variation of Potato virus Y Isolated from EgyptMedhat Helmy
Potato Virus Y (PVY) is one of the most important viruses affecting cultivated potatoes in Egypt. Different potato plants were collected from an experimental station in Giza Governorate, Egypt and were tested using RT-PCR. PVY was amplified using primers represented portion of the Coat Protein (CP) gene and 3' Untranslated Regions (UTR). Phylogenetic tree showed two main strain groups: Group I regroups PVYN and PVYNTN stains while Group II includes PVYO, PVYW and PVYN:O strains. The Egyptian PVY isolate was clearly classified within group I and was more closely related to PVYNTN strains. Ten nucleotide substitutions resulted in 3 conserved amino acid substitutions (V1→I, G7→E, M or V and S8→G) and were able to differentiate between both groups. The partial coat protein region was more diverse than that of the 3'UTR (92.6-100% and 97.7-100% identity, respectively). The 3'UTR of the Egyptian isolate showed RNA secondary structures different from those of the 5 PVY strains.

Harriet Beecher Stowe was an American abolitionist and author born in 1811 in Connecticut. She is best known for her novel "Uncle Tom's Cabin", published in 1852, which depicted the harsh reality of slavery and increased public opposition to it in the United States. The novel was a bestseller and had a profound effect on attitudes toward African Americans and slavery prior to the American Civil War. Stowe used her writing to advocate for abolition, women's rights, religious tolerance, and educational reform. She experienced personal tragedy when 3 of her adult children died, including her son Frederick who disappeared without a trace in 1870.
The poem describes the narrator's feelings of being alone from a young age. While others found joy from common experiences, the narrator's passions, sorrows, and loves came from solitary, mysterious sources in nature like storms, mountains, and the sun. As a child, the narrator felt drawn to mysteries from both goodness and evil that still bind them.

2. • EL PODEM TROBAR ...
• El nitrogen és el component principal de
l'atmosfera terrestre (78,1% en volum) i
s'obté per a usos industrials de la destil·lació
de l'aire líquid. Està present també en les
restes d'animals, per exemple el
guano, usualment en la forma de urea, àcid
úric i compostos d'aquests.
• Es presenta en estat combinat en minerals
com KNO3 i NaNO3que són els productes
comercialment importants.
• S'han observat compostos que contenen
nitrogen en l'espai exterior i l'isòtop Nitrogen-
14 es crea en els processos de fusió nuclear
a les estrelles.
• L’atmosfera de Mart conté menys d’un 3%
de nitrogen.
3. • S'OBTÉ PUR ...
Industrialment s’obté per destil·lació fraccionada de
l’aire, que conté aproximadament un 78% de nitrogen;
com que el nitrogen té un punt d’ebullició inferior al de
l’oxigen líquid, el nitrogen destil·la primer i pot separa-se
També pot obtenir-se a partir dels seus compostos, per
exemple per oxidació de l’amoníac amb òxid de coure
al roig; per descomposició del NaN3 o del dicromat
d’amoni:NaN3 (300ºC) à 2Na + 3N2 (NH4)2Cr2O7 à N2 +
Cr2O3 + 4H2O
4. APLICACIONS
·En tancs d'emmagatzemament de líquids explosius
·En la fabricació de l'acer inoxidable
·Es pot usar per a inflar els neumàtics dels automobil
·Es pot usa també per a pressuritzar bidons
de cervesa, ja que produeix bombolles més petites
que el diòxid de carboni. òbils, i reduir així l'oxidació
d'aquests.
