1	DISTRIBUTION OF ATMOSPHERIC PRECIPITATION IN THE MIDDLE PART OF THE ZERAVSHAN RIVER BASIN Saidova¹ D.A., Halimova² G.S., Hikmatov F³. ¹Senior Lecturer, Department of Hydrometeorology and Environmental Monitoring, Faculty of Hydrometeorology, Mirzo Ulugbek National University of Uzbekistan, ²Scientific supervisor, Doctor of Philosophy in Geographical Sciences (PhD), Faculty of Natural Sciences, Department of Ecology and Geography, ³Professor of the Department of Terrestrial Hydrology at the Faculty of Hydrometeorology of the National University of Uzbekistan E-mail: dono.saidova.76@gmail.com Abstract. The article is devoted to the study of peculiarities of atmospheric precipitation distribution in the middle part of the Zeravshan river basin. For this purpose the reference meteorological observation points located on the territory of the studied basin are selected. A hyetographic curve characterising changes in the amount of precipitation with the altitude of the terrain is constructed. [Saidova D.A., Halimova G.S., Hikmatov F.

2	Long Protocol versus Short Protocol in Poor Responders Wael Ahmed Ezzat Ammar; Hossam Mahmoud; Sherif M. Safwat; Marwa R. Shahine Fellow Obstetrics and Gynecology at El Galaa Teaching Hospital, Cairo Egypt Email: dr.waela3@gmail.com Abstract: Aim: Comparison between long agonist protocol and short agonist protocol in poor responders females. Methods: A retrospective study done at El GALAA Teaching Hospital over a period of 10 years from January 2015 till end of 2024. Where 200 cycles of ICSI were performed for poor responders females divided into 2 groups: Group (A) 100 cases of poor responders females who received long protocol, And Group (B) 100 cases of poor responders females who received short protocol. Comparison between two groups done according to number of days of stimulation, number of oocytes retrieved, number of M2 oocytes, pregnancy rate. Both groups were on same maximum dose of HMG stimulation drug of 450 IU of same drug. Results: As regarding: Age was of statistically insignificant difference between both groups where mean of age of group A was 37.7 ± 4.5 year, And mean of age of group was 36.7 ± 4.9 year, And P value was 8%, So Age between both groups was statically insignificant as P value > 5%. Mean of days of stimulation was Group A was 13.7 ± 3 days, while Mean of group B was 11.6 ± 2.5 days, where P value was 0% so it is statistically significant between both groups as P value less than 5%. Number of oocytes retrieved was, Mean of group A was 1.8 ± 1.8 oocytes, while group B mean was 2.3 ± 2.2 oocytes, And P value was 5%, So Number of oocytes retrieved was statistically significant between both groups as P value was not more than 5%. Number of M2 oocytes was, Mean of Group A was 1.6 ± 1.5 M2, And mean of Group B was 2.5 ± 2.1 M2, where P value was 0 %, So Number M2 of oocytes retrieved was statistically significant between both groups as P value was not more than 5%. Pregnancy rate was, Mean of group A was 3% ± 0.17% oocytes, while group B mean was 4% ± 0.19% oocytes, And P value was 16%, So pregnancy rate was statistically insignificant between both groups as P value was more than 5%. Conclusion: In poor responders females short protocol was better than long protocol specially in number of days of stimulation, number of oocytes retrieved and number of M2 oocytes.

3	Effects of physical characteristics of landscapes of Uzun District on population density Mingaliyev Ravshan Olim ugli¹, Sharipov Shavkat Mukhamajanovich², Khayitmurodov Alijon Olimjon ugli¹ ^1. PhD student of the Department of Physical Geography of the National University of Uzbekistan 100174, Uzbekistan ^2. Doctor of Geographical Sciences (DSc), Dean of the Faculty of Geography and Geoinformation Systems of the National University of Uzbekistan 100174, Uzbekistan xayitmurodovalijon97@gmail.com Abstract: This article covers the issues of determining the boundaries of landscapes, their classification, determining the population density in landscapes, and analyzing the effects of physical characteristics of landscapes on population density. Historical-evolutionary, genetic and structural criteria have been used to determine the boundaries of landscapes in Uzun district. Based on the theory proposed by V.A. Nikolayev, Uzun district landscapes are classified and 13 landscape species are distinguished in this area. The area of landscapes and their population, as well as population density, have been determined. The impact of physical features of landscapes on population density has been comprehensively analysed. A landscape map and population density map of Uzun district have been created.

4	*Impact of planting density on chemical composition, in vitro* gas production evaluation and yield of Corn Silage Hamed Mohamed Gaafar, Reda Abdelbary Mesbah Animal Production Research Institute (APRI), Agricultural Research Center, Dokki, Giza, Egypt. hamedgaafar@gmail.com Abstract: In a split plot design, a single cross hybrid maize (SC 10) was utilized with randomized complete block creation at low and high planting density of 20 and 30 thousand plants/fed, respectively. When the maize plants reached dough maturity (92 days), they were cut into whole pieces and put into three double-layered plastic bags for every density. The bags were kept for 35 days after being thoroughly compressed to eliminate any last traces of air. The findings showed that corn silage with lower plant density had lower CF and fiber fractions and greater NFE and NFC levels than silage with higher density (P < 0.05). As plant density decreased, there was a considerable rise in gas output (C), the soluble to insoluble matter ratio (A), and gas production. As planting density grew, production of methane rose dramatically (p < 0.05). Low density planting was associated with higher (p < 0.05) levels of microbial protein (MP), soluble fraction (GPSF), insoluble fraction (GPNSF), intake of DM, digestibility of OM, degradability of DM in vitro (IVDMD), and short-chain fatty acids. In the meantime, metabolizable and net energy were almost the same for high and low planting density. However, high plant density corn silage achieved higher yield of dry crop, protein, ME and NE.

5	Review On Fowl Cholera Marie Teshger Tsehay¹, Addisu Gebru Zeru², Getnet kindu Mengist³ ¹Department of Animal Health, Banja wored livestock office, Injibara, Ethiopia ²Department of Animal Health, Dangila city Adminstration Agriculture office. Dangila, Ethiopia ³Department of Animal Health, Durbete poly Techinque College p.box Durbete, Ethiopia teshagermarie@gmail.com Abstract: Pasteurella multocida subspecies multocida is the most common cause of fowl cholera, although pasteurellamultocida subspecies septica and gallicida may also causefowl cholera-like disease to some extent. However, the virulence properties of the different subspecies for various hosts have not been elucidated. The seventy and incidence of pasteurellamultocida infections may vary considerably depending on several factors associated with the host (including species and age of infected birds), the environment and the bacterial strain. No single virulence factor has been associated with the observed variation in virulence among strains. Possible virulence factors include the following: the capsule, endotoxin, outer membrane proteins, and iron binding systems, heat shock proteins, neuraminidase production and antibody cleaving enzymes. Carrier birds seem to play a major role in the transmission of cholera. The site of infection for pasteurellamultocida is generally believed to be the respiratory tract. The outcome of infections may range from peracute/acute infections to chronic infections. In the former type of infections, few clinical signs are observed before death and the lesions will be dominated by general septicemia lesions. In chronic forms of pasteurellamultocida infections, suppurative lesions may be widely distributed, often involving the respiratory tract, the conjunctiva and adjacent tissues of the head. Diagnosis is always dependent the development of safe and efficient live vaccines still poses problems. [Marie Teshger Tsehay; Addisu Gebru Zeru; Getnet kindu Mengist. Review On Fowl Cholera.
