A Nonlinear Panel ARDL Analysis of Pollution Haven/Halo Hypothesis

Zamira ÖSKÖNBAYEVA

There is a growing popularity for the nonlinear econometric approaches, since linkages among variables are not always linear. Nonlinear approaches provide a broader range of knowledge compared to the linear model. This research aims to assess the impact of foreign direct investment on pollution. To capture the potential asymmetries resulting from rise and fall in the foreign direct investments, the nonlinear panel autoregressive distributed lag approach is employed. In the empirical analysis, annual data of selected 22 transition economies from 1995 to 2016 is utilized. The findings highlighte ...Более

Potential Impacts of Climate Change on Plant Diversity of Sary-Chelek Biosphere Reserve in Kyrgyzstan

Nazgül İMANBERDİYEVA | Zeki SEVEROĞLU

The Sary-Chelek Nature Reserve established in 1959 with an area of 239 km2 and declared as a UNESCO-MAB Biosphere Reserve in 1978 is located on the southeast-facing slope of the northern Chatkal Range in central Jalalabad province. It is centered around the scenic Sary-Chelek Lake. The mountains immediately surrounding the lake abound in exceptionally diverse flora and fauna, what may be the widest variety found in the Tian Shan. The area is spread over varied ecosystems and habitats, which include the forests of spruce and juniper together with the forests of wild fruits and nuts and riparian ...Более

No Evidence of an Elevation Effect Caused by Temperature Differences on Soil Microbial Properties in a Walnut Fruit Forest in Kyrgyzstan

Cıldız ÖSKÖNBAEVA

This study is to investigate the effect of differences in annual average temperature on soil microbial communities as caused by elevation in walnut-fruit forests in Kyrgyzstan with similar vegetation. Soil samples (n 10 per site) were collected from top- and subsoil at three elevation levels (1000, 1300 and 1600 m above sea level) with an average temperature difference of 1.3 °C between sites and analysed for soil chemical and biological properties. All soil properties showed high variability within, but most revealed no differences between elevation levels. Microbial biomass, activity and com ...Более

Possibilities for Prediction And Evaluation of the Carbon Footprint in Furnace Fuel Oil Combustion in Medium- and Low-Power Boilers

Mirlan MOLDOBAYEV | Zarlık MAYMEKOV

To predict and evaluate the carbon footprint in the gas phase, furnace fuel oil oxidation in excess air (alpha factor 1.3) was studied over a wide temperature (T 298–3000 K, P 0.1 MPa). Equilibrium thermodynamic parameters (entropy, enthalpy, and internal energy) and the concentration distributions of C-, S-, N-, O-, and H-containing components and active particles in the gas phase were determined. Based on the total concentration distribution of C-, S-, N-, O-, and H-containing components and active particles in the gas phase, the weight content of carbon was calculated. Taking into account t ...Более

Flora and Plant Formations Distributed in At-Bashy Valleys–Internal Tien Shan in Kyrgyzstan and Interactions with Climate

Nazgül İMANBERDİYEVA

In this chapter, the flora and vegetation of Kyrgyzstan’s At-Bashy valley and inner Tien Shan, together with the vegetational changes due to climatic impacts, are presented. The data presented covers the period between 2000 and 2014. More than 50 % of the higher plants in Kyrgyzstan grow on a very small territory. There are more than 4100 species distributed in the country and 1600 of these possess economic and practical value. Flora in At-Bashy valleys is represented by 222 species of higher plants belonging to 130 genera and 35 families. Steppes are a dominant vegetation type in the study ar ...Более

Seismogenic destruction of the Kamenka medieval fortress, northern Issyk-Kul region, Tien Shan (Kyrgyzstan)

Kubatbek TABALDİYEV

A paleoseismological study of the medieval Kamenka fortress in the northern part of the Issyk-Kul Lake depression, northern Tien Shan in Kyrgyzstan, revealed an oblique slip thrust fault scarp offsetting the fortification walls. This 700 m long scarp is not related to the 1911 Kebin Earthquake (Ms 8.2) fault scarps which are widespread in the region. As analysis of stratigraphy in a paleoseismic trench and archaeological evidence reveal, it can be assigned to a major twelfth century a.d. earthquake which produced up to 4 m of oblique slip thrusting antithetic to that of the nearby dominant fau ...Более

Assessment of the impact of the different settlement patterns on the summer land surface temperature: Elazig

Hasan YILMAZ

Currently, cities are at the center of the debate on global warming since land use and land cover change (LULC) in cities are considered to be major contributors to global climate change. In this study, Carsi and Dogukent Neighborhood areas in the city center of Elazig province, Turkey, were examined in terms of land use and land cover (LULC). Both areas were chosen because they have different patterns and features, such as different residential densities, street aspect ratios and orientations, impervious surfaces, vegetation, and elevations. The aim is to assess the effect of the different pa ...Более

Agro-morphological traits of Cicer reticulatum Ladizinsky in comparison to C. echinospermum P.H. Davis in terms of potential to improve cultivated chickpea (C. arietinum L.)

Mirlan TALİP

Germplasm collections of C. reticulatum and C. echinospermum are limited, while both species face threats from over-grazing and habitat change in their natural environments. Recently many new accessions of C. reticulatum and C. echinospermum were collected in east and south-east Anatolia (Turkey) but they have not yet been evaluated for agro-morphological traits. Therefore, the current study investigated agro-morphological traits of new germplasm sources of C. reticulatum and C. echinospermum and evaluated resistance to biotic and abiotic stresses for chickpea improvement. The most attractive ...Более

First report of dry rot of potato caused by Fusarium sambucinum in Kyrgyzstan

İsmail ERPER | Sezim COLDOŞBEKOVA

In October 2020, the presence of an intense Fusarium dry rot disease was detected during a survey of potato tubers in the production storage facilities in Chui region, Kyrgyzstan. The species of Fusarium isolates, obtained from infected tubers, were identified as Fusarium sambucinum by using morphological features and phylogenetic analyses of the transcription elongation factor 1-alpha (EF1-alpha) gene. The isolates were pathogenic to potato tubers, and Koch

The utility ofTrichodermaspp. isolates to control ofXylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae)

İsmail ERPER

The invasive ambrosia beetle,Xylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae), is a serious pest of hazelnut in Turkey, which is the biggest hazelnut producer in the world. In this study, the utility of four isolates representing differentTrichodermaspecies (T. harzianum,T. hamatum,T. asperellum, andT. atroviride) was evaluated on survival, gallery behavior and brood production ofX. germanusby effecting the symbiotic fungal development at laboratory conditions. Hazelnut branches were exposed to fungal suspensions (1 x 10(6)and 1 x 10(8)conidia mL(-1)doses) for about 30 s. ...Более
