Title: The Determination of the Optimum Parameters for the Formation of Silver Nanoparticles by Aspergillus Niger BDU-A4
Authors: Musayev, Eynulla
Abstract: In this work, the formation of silver nanoparticles was investigated by Aspergillus niger
BDU-A4 at different stages/phases/culture media: a) pH: 4.82,5.79,7.42,8.88, 9.86;b)
indicators of temperature (20°C, 25°C, 30°C, 37°C və 45°C) and c) indicators of different
concentration of the salt of AgNO3. As a result of UV-V, absorbance spectrum is defined as
the optimal conditions for the formation of maximum amount of Ag nanoparticles from
AgNO3 - substrate by Aspergillus niger BDU-A4. This condition determined pH = 7.4 at 37
°C,with 10 grams of biomass within 1mm AgNO3 solution in 100 ml suspension during 6
hours incubation.2021-01-01T00:00:00ZPhylogenetic Relationships of some Wild and Cultivated Barley Accessions Using Seed Storage Protein Markers

Title: Phylogenetic Relationships of some Wild and Cultivated Barley Accessions Using Seed Storage Protein Markers
Authors: Serpoush, Moozhan
Abstract: Barley is of renewed interest throughout the world because of its nutritional value and low
glycemic index. It has been suggested that biochemical accomplished with molecular
markers can be used to solve population diversity of barley. Hordeins are the storage proteins
of the wild and cultivated barley samples. For this reason, we analyzed genetic diversity in
the storage protein hordein encoded loci in seeds from 106 accessions of wild and cultivated
of barley accessions from different countries. Cluster analysis by using Nei genetic distance
and UPGMA methods all studied wild and cultivated barley accession divided into 6 main
groups. Groping of Azerbaijan wild and cultivated barley accession in the same cluster
showed that Azerbaijan cultivated barley accessions was clearly distinguished from its wild
accessions. The presence of high level of diversity among the tested genotypes grouped into
divergent clusters indicated their suitability for further research can be done in this direction
by selecting superior barley genotypes.2021-01-01T00:00:00ZPathologoanatomic Changes in Birds with Associated Infections (Infectious Bronchitis and Esherichiosis)

Title: Pathologoanatomic Changes in Birds with Associated Infections (Infectious Bronchitis and Esherichiosis)
Authors: Gasimov, Rustam
Abstract: Infectious diseases tend to be widespread in large poultry complexes containing a large
number of birds in limited areas. It is an actual problem for industrial poultry farming. The
presence of infectious diseases of viral and bacterial etiology in poultry farms has a negative
effect not only on the exacerbation of the epizootic situation, but also it leads to a sharp
decline of economic indicators. These infectious diseases are often associated and considered
as a medical and environmental problem, due to the risk of spread among people.
Experimental infection of chickens causes a slowdown in the growth and loss of cilia of
epithelial cells, dilatation of tubular glands, infiltration of lymphocytes, mononuclear cells,
plasma cells, as well as edema and fibroplasia of the proper layer of all parts of the oviduct.
So, the clinical signs of IBC and its mixed course with escherichiosis, pathological changes
and histological examination allow us to establish a preliminary diagnosis.2021-01-01T00:00:00ZHistory and Future Prospects of Gazelle (Gazella Subgutturosa Guld, 1780) Population on the Island of Khara Zira

Authors: Sarukhanova, Sevinj; Askerov, Elshad; Tagıyeva, Yelena; Hasanov, Nijat
Abstract: The article considers the history of development of gazelle population released on the island
of Khara Zira in 1965. Natural forage resources of these antelopes were estimated, factors
influencing the dynamics of the gazelles population are studied, future prospects of this
population are discussed and finally suggestions are made.2021-01-01T00:00:00Z
