MODERN ADVANCES IN THE SYNTHESIS OF NEW DERIVATIVES OF ACETYLENE DITHIOCARBAMATE AND THEIR BIOLOGICAL ACTIVITY
Makhsumov Abdukhamid Gafurovich, Ismatov Dilmurod Nurillaevich, Valeeva Nailya Gennadievna, Asadova Rano Dilmuratovna, Ruzmatov Bobur
Abstract:
The article shows the results of the preparation of 1-bromopropargyl esters of substituted benzoates based on bromo-substituted benzoates and propargyl alcohol by interaction with NaSH, the synthesis of 1-thiol-propargyl esters of substituted benzoates with high yields. It was shown that the reaction between 1-thiol propargene benzoate and 1-isocyanate proceeds according to the AN nucleophilic addition mechanism with the quantitative formation of dithiocarbamate compounds. The structures of the synthesized compounds were established and their biostimulating activity was shown.

BACKGROUND ON THE DEVELOPMENT ISSUES OF SOIL EROSION OF SLOPING LANDS OF AZERBAIJAN
Prof. Academician RAS. B.H.Aliyev, Prof. RAE Z.H. Aliyev
Abstract:
The article examines the issues of the possibility of studying the areas of development by soil erosion and its control. The study proved that the development of soil erosion is based on the forming impact of natural and anthropogenic factors. The degree of potential danger and the possibility of prevention, taking into account the preservation of the environmental situation in the foothills of the Upper Shirvan in the example of the Shamakhi district of the Republic of Azerbaijan, were studied. The main tasks of the study were a determination of the amount and degree of development of eroded and erosionprone soils of the foothill zones carried out on the basis of soil erosion surveys of the farms of the republic.

POLLUTION OF NATURAL ECOSYSTEMS, THE BIOSPHERE RADIONUKLIDAMY, AND ITS IMPLICATIONS
Dr, Prof. RAE Aliyev Z.H.
Abstract:
Now humanity is understood not only the magnitude of its creativity, but its complete dependence on the environment Wednesday. However, this understanding until nevseobĀ» by and often submissive short-term selfish interests (situation, economy, etc.); ended in the twentieth century, a century of great discoveries and global achievements in the sciences, engineering, economics, and human culture. In this century, along with the progress occurred global destruction of nature, pollution Wednesday. Scientific and technical progress was threaten green civilization. From the middle of the century, mankind departed entered a new phase of its development in the no sphere i.e. when the only alternative becomes a balanced national economy conducting "joint" with all the elements of nature, i.e. on a smoke break already established natural biogeocenozam populations and communities, and combining with them, complementing them, sozhitelstvuja them

REVIEW AND ASSESSMENT OF THE USE OF IRRIGATION SYSTEMS IN CONDITIONS OF ACUTE RESOURCE SHORTAGE IN THE CONDITIONS OF AZERBAIJAN
Prof. RAEAliyev ZakirHuseynoqlu
Abstract:
Simmer Blass and his twin daughters were able to transfer the ACL to the University of Clermont. The Lakinobanalist was not given up. (the so-called plastic bottlenecks). In 1948, the injection of the injection drug of Seco Blass injectable injection and injection of the injectable drug for injection due to injection due to the biochemistry of chrysophilic biochemistry. One of the worst attackers, Sima Blass, was Israel's successor in the 1962 Diving Water Pipe. In 1968, the southernmost region in southern Kyrgyzstan was the epicenter of 800 headquarters. Then, in several countries, the temperature of the tsunami declined. Only in the 1970s, irrigated farms grew to 4.2 million degrees in the 1970s, in 1975 there were 110,000 recruiters and the 1980s in the south by 350,000 hectares. This steam boom absorbs ACS at 172 mAh. Damages and dams caused by irrigation can be caused by unevenness of diarrhea irrigation systems; Allow the beard to go to the watercourse water and bring the cow to a low rate, allow the water to be thrown clockwise and make sure that the erosion of the fungi is extinguished.[

SPATIAL ANALYSIS OF DATA ON THE BASIS OF THE DIGITAL MODEL OF RELIEF AND LOCALITY
Prof. Z.H.Aliyev
Abstract:
The article examines the issues of studying the degree of susceptibility of sloping lands in Azerbaijan in the example of specific administrative-territorial units, flat areas with a slope of up to 6% (about 3.50) are concentrated in Akhsu district - 71%, and in Shemakha - almost 49%. The steepest slopes are observed in the Ismaili region, where almost 26% of the territory has a slope of 10-18%, 30% of its area slope is 18%.

DIFFICULT TOPICS IN SECONDARY SCHOOL BIOLOGY CURRICULUM AS PERCEIVED BY SECONDARY SCHOOL STUDENTS IN EZEAGU LOCAL GOVERNMENT AREA OF ENUGU STATE
EZECHI, Nnenna Grace
Abstract:
This study was conducted to determine the difficult topics in secondary school biology curriculum as perceived by secondary school students in Ezeagu Local Government Area of Enugu State. Survey research design was adopted for the study. Three research questions were formulated to guide the study. The population of the study was all the students in the twenty eight (28) public secondary schools in Ezeagu L. G. A.. The sample consisted of three hundred senior secondary school two (SS 2) students randomly selected from ten (10) secondary schools in the area of study. Data was collected using structured questionnaire developed by the researcher and validated by experts with reliability index of 0.97. The collected data collected were analyzed using mean. The findings of the research revealed that mendelian genetics, genes and chromosomes, mitosis and meiosis, nervous system, protein synthesis, DNA synthesis, homeostasis, photosynthesis, enzymes, transport of materials, ecology, evolution, skeletal system, classification and endocrine system were perceived difficult by secondary school student. Lack of suitable models in school, too technical, abstract and complex terminologies and lack of good instructional materials to drive home the lessons among others were identified to be the major cause of the perceived difficulties by secondary school students. Recommendations included among others that Government through grants should restock these laboratories in terms of necessary equipment or apparatus, chemicals, and models and other required teaching and learning materials to ensure effective and efficient teaching of biology in schools. And also, there should be rigorous regular monitoring of the teaching of biology in public secondary schools by the local school authorities as well as by external authorities who may include Post Primary School Management Board (PPSMB) officers, Local Government Education Authorities, and state ministry of education so that the teachers of biology intensify their lesson preparations and improvisation.

ANAEROBIC PALM OIL MILL EFFLUENT TREATMENT USING A THERMOPHILIC SLUDGE FROM THE EFFLUENT
M.C. ONYIA, OGBUANU, CYRIL .C
Abstract:
A mixed culture sludge of a mesophilic pond palm oil mill effluent was used for thermophlic anaerobic treatment of palm oil mill effluent in a batch fermenter. The cultivation was carried out successfully while being monitored. The cultivated thermophilic mixed culture could reduce at least 80% of Chemical Oxygen Demand (COD) in palm oil effluent with a mixed liquor suspended solid concentration of 20,000mg/L after 10 days operation producing biogas with average 75% methane.
