  • The study of behavior and values of deformations in the geological medium makes the scientific basis of the methodology of synthesis of true values of parameters of its physico-mechanical and density properties taking into account the influence of geodynamic impacts. The segments of continuous variation of homogeneous elastic uniform deformations are determined under overall compression of the medium. The limits of these segments are defined according to the criteria of instability (on geometric form changes and on "internal" instability). Analytical formulae are obtained to calculate current and limiting (critical) values of deformations within the framework of various variants of small and large initial deformations of the non-classically linearized approach of non-linear elastodynamics. The distribution of deformation becomes non-uniform in the medium while the limiting values of deformations are achieved. The proposed analytical formulae are applicable only within homogeneous distribution of deformations. Numerical experiments are carried out for various elastic potentials. It is found that various forms of instability can precede phase transitions and destruction. The influence of these deformation phenomena should be removed while the physico-mechanical and density parameters of the deformed media are determined. In particular, it is necessary to use the formulae proposed in this paper for this purpose.

  • It is undertaken systematization of results of satellite and ground observation parameters characterizing a current condition and climatic variability of two selected geographical areas. One of them covers territory of Azerbaijan and another covers a wide area of Caspian See region. Average values and mean square deviations of following values are investigated: outgoing long wave radiation during a day and night (in nebulosity and cloudless). absorbed within a day of the stream of a sunlight of the system in "a terrestrial surface-atmosphere". degree of a covering by clouds of the selected areas during a day and at night, ground temperature values of air. pressure and speed of a wind. Monthly average values of corresponding parameters create a basis of suggested investigations. It has been presented features of a time course of investigated parameters for each month and year in the whole due to the continuously observations since 1982-2000. The scientific problem consists that there are no existed models which authentically would be cover the main aspects of a realities specified changes: they are identified by economic activities. growth of the population and other features of development of a human society or internal fluctuations of biogeophysical/climatic system. Possibilities of predictability of biosphere and climate changes depend on available timely supervision. adequacy of construction of appropriate models. understanding of mechanisms of direct and feedback influences in such complicated systems.

  • Purpose: In the current era of rapid development of the information and communication technologies (ICT) sector, the formation of an effective regulatory approach is important. There are some methodological shortcomings and difficulties in the approach system of international organizations that assesses the level of application of ICT in various areas in terms of quantity and quality. The basic element of economic growth differs according to the economic conditions prevailing in the period and the country. While the agricultural sector plays an active role in economic growth or development in an underdeveloped country, in a developed country, capital-intensive and even technology-intensive production is the main element of economic growth. From this point of view, the contribution of information and communication technologies (ICT) to Azerbaijan's socio-economy for the period between 2010-2020 will be examined. Research design and methodology: The unit root test and Granger causality test were applied by taking the CDPPC per Capita, Employment, and Unemployment Rate from the social-o-economic data as the dependent variable, fixed and mobile phone usage and internet usage as the independent variables. The principal results: According to the results obtained; It has been determined that the use of ICT positively affects the socio-economic economic situation.

  • 2000년 이후 국제유가의 불안정성으로 인한 에너지 자원 확보의 중요성이 강조되면서 에너지 자원의 대안 시장으로 카스피해 연안국가들에 대한 관심이 고조되고 있다. 특히 아제르바이잔은 중앙아시아 신흥석유 수출국으로서 해외자본의 유입, BTC 송유관 개통 등으로 인해 급속한 경제성장을 이루었다. 그러나 높은 경제성장에도 불구하고 경제구조가 에너지 산업에 집중되는 등 경제구조의 불균형을 보이고 있으며, 최근 실질환율 상승의 압박 및 인플레이션이 가속화되고 있다. 아제르바이잔 경제의 지속가능성을 파악하기 위해 본 연구에서는 분석대상기간을 2001년 1월부터 2007년 12월까지의 전체 표본기간, BTC 개통을 기점으로 BTC 개통 이전과 이후의 기간 등 세 단계로 구분하였으며, 벡터오차수정모형을 이용하여 분석을 시도하였다. 실증분석 결과, 아제르바이잔은 분석기간 동안 경기침체 증상을 보였으며, 이는 고유가의 영향과 BTC 송유관 개통으로 인한 수출의 급증이 아제르바이잔 실질환율을 하락(평가절상)시키는 주원인임을 확인하였다. 이러한 결과는 장기적인 경제발전의 기반이 될 제조업의 경쟁력에 부정적 영향을 미칠 것으로 예상된다.

  • Urban geology is the study of urban geologic environments to provide a scientific basis for rational land use planning and urban development and provides information on geologic environments as a basis for city planners. Based on AEG recommendations, urban geological studies covered the urbanism and historical backgrounds, geological setting, engineering geological constraints and environmental assessments of understudied cities. The aim of this study is to provide a good view of urban geology of Tabriz city the capital of East Azerbaijan province in Iran. The topics of discussions about Tabriz city urban geology are included geologic (geomorphology, geology, climatology and hydrogeology), engineering geological (earthquake, landslide and geotechnical hazards investigations) and environmental characteristics (air, soil and water hazards assessment).The results of the urban geologic studies indicated that Tabriz city in terms of engineering geological and environmental constraints is at high risk potential and in terms of seismic activity and landslide instability is highly potential. In terms of air, soil and water pollution there are many important environmental concern in this city.

  • We have investigated the long term variability of the intensities of the broad-line region emission lines in the UV spectra of Seyfert I galaxy NGC 5548 from 1973-1996. We have obtained the following results: 1) a high level correlation between the intensities of emission lines as well as between intensities of emission lines and continuum fluxes was discovered. With increasing wavelength the correlation in both cases becomes weaker, 2) the relationship between the intensity of emission lines and the flux radiation in the continuum can be expressed by a power law function with coefficients of ${\alpha}{\approx}0.8-1.1$ for different lines. When the difference between the wavelengths of spectral lines and the continuum is increased, the value of the power function decreases, and 3) it was found that the magnitude of the variability of the line intensities are weaker than the range of variability of the continuum fluxes. The magnitude of the variability of the line intensities and the continuum fluxes increase at longer wavelengths.

  • Background: There is a close relationship between Helicobacter pylori (H pylori)-specific factors and different gastroduodenal diseases. The present study aimed to investigate the prevalence of vacA d1, d2 genotypes in the H pylori isolates from patients with gastric adenocarcinoma, peptic ulcer disease (PUD) and gastritis in East Azerbaijan region, where the incidence of gastric cancer (GC) is high. Strains isolated from this area are likely to be of European ancestry. Materials and Methods: In this study, genotyping of the vacA d region of 115 isolates obtained from patients with different gastrodoudenal diseases was accomplished by PCR methods. In addition to PCR amplification of H pylori 16S rDNA, rapid urease tests or histological examination were used to confirm the presence of H pylori in biopsy specimens. Data were collected and analyzed using SPSS version 19. Results: Of the total of 83 H pylori isolates, 36 (43.4%) contained the d1 allele and 47 (56.6%) were subtype d2. The results of the multiple linear/logistic regression analysis showed high correlation between allele d1 and gastric adenocarcinoma or PUD. Conclusions: This study suggests that the H pylori vacA d1 genotype helps predict risk for gastric adenocarcinoma and PUD in East Azerbaijan, Iran.

  • Stomach cancer, the fourth most common cancer and the second leading cause of cancer-related death through the world, is very common in parts of Iran. Geographic variation in the incidence of stomach cancer is due to many different factors. The aim of this study was to assess the geographical and spatial distribution of stomach cancer in Iran using data from the cancer registry program in Iran for the year 2009. The reported incidences of stomach cancer for different provinces were standardized to the world population structure. ArcGIS software was used to analyse the data. Hot spots and high risk areas were determined using spatial analysis (Getis-Ord Gi). Hot and cold spots were determined as more than or less than 2 standard deviations from the national average, respectively. A significance level of 0.10 was used for statistical judgment. In 2009, a total of 6,886 cases of stomach cancers were reported of which 4,891 were in men and 1,995 in women (standardized incidence rates of 19.2 and 10.0, respectively, per 100,000 population). The results showed that stomach cancer was concentrated mainly in northwest of the country in both men and women. In women, northwest provinces such as Ardebil, East Azerbaijan, West Azerbaijan, Gilan, and Qazvin were identified as hot spots (p<0.1). In men, all northwest provinces, Ardabil, East Azerbaijan, Gilan, Qazvin, Zanjan and Kurdistan, the incidences were higher than the national average and these were identified as hot spots (P<0.01). As stomach cancer is clustered in the northwest of the country, further epidemiological studies are needed to identify factors contributing to this concentration.

  • 논문은 아제르바이잔의 정체성을 형성해 온 역사적 문화적 원천을 페르시아, 투르크, 러시아의 영향이라는 측면에서 분석하여 그 복합적인 성격을 해명하고, 1991년의 독립 초기 그것이 아제르바이잔의 대외정책에 미친 영향과 그 귀결을 살펴보고자 한다. 오늘날의 세계에서 정체성은 사회적, 정치적, 경제적, 문화적 맥락에서 뿐만 아니라 복합적인 맥락에서 진행되는 다양한 변화 속에서 형성되고 표현된다. 이러한 정체성의 표출은 다원적인 환경에서 종종 배타적인 결과를 가져오기도 한다. 독립 이후 PFA 정부는 아제르바이잔의 풍부한 문화적 유산과 다면적인 정체성을 강조하기보다는 종족적 기원과 아제르바이잔의 터키성(Turkishness)을 강조하는 논리를 내세웠다. 국내적으로 볼 때, 종족 민족에 기반을 둔 대외정책은 소비에트 하에서 아제리 민족에 흡수되었던 아제르바이잔의 쿠르드인조차도 소외감과 배신감을 느꼈을 정도로 심각한 실패에 직면했다. 국제적으로 볼 때, PFA 정부의 대외정책은 러시아와 이란으로 하여금 등을 돌리게 만들었을 뿐만 아니라, 터키가 러시아와의 관계 악화를 우려함에 따라 터키에 대한 교섭력도 약화시켰다. 이에 따라, PFA 이후에 집권한 헤이다르 알리예프는 아제르바이잔 정체성의 네 가지 요소(페르시아적인 정체성, 투르크적인 정체성, 러시아적인 정체성, 아제르바이잔적인 정체성)를 모두 활용하여 대외정책의 방향을 결정하였던 것이다.
