A comparison of foreign direct investments in Eurosian countries to world trend in the period of 1995-2011

Küreselleşen ve gün geçtikçe sınırların azaldığı dünyamızda doğrudan yabancı sermaye yatırımları, başta ekonomik büyüme ve işsizlik olmak üzere, ülkelerin birçok farklı makro verisini etkilemektedir. Mevcut araştırmalar, doğrudan yabancı sermaye yatırımlarının ekonomik büyümeyi etkilemesi yönünde güçlü bir nedensellik ilişkisi olduğunu desteklemektedir. Ekonomik büyümenin doğrudan yabancı sermaye yatırımlarınıetkilemesi yönünde ise, daha zayıf bir pozitif nedensellik ilişkisi tespit edilmiştir. Böylece, ekonomik büyümenin bir sonucu olarak, işsizlik oranlarında bir azalma beklenebilir. Bu çalışma, yedi Avrasya ülkesinin (Azerbaycan, Kazakistan, Kırgızistan, Tacikistan, Türkiye, Türkmenistan ve Özbekistan) 1995 yılından 2011'e kadar çekmiş olduğu doğrudan yabancı sermaye yatırımları trendini, hem bu ülkeler arasında hem de dünya trendi ile karşılaştırmaktadır.The world which rapidly globalizes and where the boundaries diminish day by day, the foreign direct investments affect many diverse macroeconomic variables, specifically economic growth and unemployment. Most current studies support that there exists a strong causality relationship between foreign direct investments and economic growth.On the other hand, there exists a weaker positive causality relationship between economic growth and foreign direct investments. Moreover, it is an undeniable fact that the economic growth leads to a decline in unemployment. This study aims to compare the foreign direct investment trends of seven Eurasian countries (Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkey, Turkmenistan and Uzbekistan) in the period of 1995 and 2011. The results are compared to both the world foreign direct investment trend and the other Central Asian countries.Publisher's Versio

GC/MS analysis and antimicrobial activity of essential oils of Telekia speciosa (Schreb.) Baumg.

Telekia speciosa (Schreb.) Baumg., Asteraceae, is widespread in Eastern and Central Europe and the Balkan Peninsula. Previous phytochemical investigations have revealed T. speciosa as a rich source of sesquiterpene lactone – isoalantolactone, especially in its underground parts. The aim of the present study was to analyze the essential oils from aerial and underground parts of T. speciosa and investigate their antimicrobial activity. Essential oils were obtained by hydrodistillation. Their chemical compositions were determined by GC-FID/MS method leading to the identification of 67 compounds in total, with 15.77% oxygenated monoterpenes, 7.77% sesquiterpene hydrocarbons, 49.14% oxygenated sesquiterpenes and 12.37% other compounds from aerial parts, and 3.80% oxygenated monoterpenes, 3.13% sesquiterpene hydrocarbons, 90.33% oxygenated sesquiterpenes from underground parts essential oil. The main components from essential oil aerial parts were (E)-nerolidol (11.54%) and caryophyllene oxide (10.54%), while isoalantolactone was the predominant component from essential oil underground parts (83.41%). The minimum inhibitory concentration, minimum bactericidal/fungicidal concentration of the essential oils were evaluated against six strains of bacteria and two strains of fungus using in vitro microdilution method. Both oils presented antimicrobial properties against pathogens Staphylococcus aureus, Bacilus cereus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. Inhibition of growth of tested microorganisms by T. speciosa UEO was achieved with MICs ranging 1.0 to 11.0 mg mL-1, while MICs of AEO varied from 4.0 to 30.0 mg mL-1. The obtained results contribute to knowledge of antimicrobial properties of T. speciosa, which support traditional usees underground parts of the plant

Experimental study of a fast gas-particle separator

A horizontal rapid gas-particle separator dedicated to the Fluid Catalytic Cracking process was tested on a small scale cold Circulating Fluidized Bed. Air (density 1.2 kg/m3, dynamic viscosity 1.8×10-5 Pa.s) and typical FCC particles (density 1400 kg/m3, mean diameter 70 mm) are used. The inlet gas velocity is kept constant at 7.3 m/s while the inlet solid loading and the separator dipleg back pressure range from 0 to 16 kg/kg and 100 to 500 Pa, respectively. Solid collection efficiency and pressure drop are studied. A model based on cyclone concepts is proposed. The solid collection efficiency increases with the inlet solid loading and reaches an asymptotic value close to 95 % when the inlet loading is above 5 kg/kg. Two flow regimes are observed in the separator dipleg through the range of inlet solid loadings, related to the available flow section modification and the interstitial gas entrainment. At constant gas collection efficiency, the separator pressure drop is maximum under single-phase flow conditions and reaches a minimum when the inlet solid loading is close to 2.5. The pressure drop increases again for higher inlet solid loading. The final modeling allows good prediction of the separator operation for all inlet solid loading conditions when the gas collection efficiency is at 100 %

Reversible metal-insulator transition of Ar-irradiated LaAlO₃/SrTiO₃ interfaces

The conducting state of a quasi-two-dimensional electron gas (q2DEG), formed at the heterointerface between the two wide-bandgap insulators LaAlO₃ (LAO) and SrTiO₃, can be made completely insulating by low-energy, 150-eV, Ar⁺ irradiation. The metallic behavior of the interface can be recovered by high-temperature oxygen annealing. The electrical transport properties of the recovered q2DEG are exactly the same as before the irradiation. Microstructural investigations confirm that the transition is not due to physical etching or crystal lattice distortion of the LAO film below its critical thickness. They also reveal a correlation between electrical state, LAO film surface amorphization, and argon ion implantation. The experimental results are in agreement with density functional theory calculations of Ar implantation and migration in the LAO film. This suggests that the metal-insulator transition may be caused by charge trapping in the defect amorphous layer created during the ion irradiation

Gender Equality in the Movies Nominated for the Golden Arena Award at the Pula Film Festival 2010-2020

Ovaj rad analizira rodnu ravnopravnost u filmovima koji su bili nominirani za, odnosno koji su osvojili Veliku zlatnu arenu za najbolji film na Pulskom filmskom festivalu u periodu od 2010. do 2020. godine, koristeći metode kvalitativne analize sadržaja i analize narativa. Kako bih otkrila postoji li rodna neravnopravnost u režijskom sektoru, ali i samom sadržaju pobjedničkih filmova, analizirala sam pojedine prikaze ženskih i muških likova, okvir unutar kojeg su prikazani te njihove odnose. Žene su u analiziranim filmovima prikazane kao podrška protagonistu, iako nisu uvijek sporedni likovi. Prikazane su kao submisivne i pasivne; one su majke, supruge i kćeri, određene isključivo svojim odnosom s muškarcima. Iako su u nekim od filmova protagonistice, njihovo djelovanje pod utjecajem je muškarca – protagonista iz sjene. Muškarci su prikazani kao dominantni, asertivni i bez emocija; oni su oličenja patrijarhata. Direktno ili indirektno pokreću radnju, iako nisu uvijek protagonisti. Patrijarhat se u filmovima koje je filmski festival u Puli procijenio najvrjednijima u analiziranom razdoblju ne ogleda kroz velike stvari – to su sitnice koje smo kao društvo toliko normalizirali da i sami nesvjesno sudjelujemo u njima.This paper analyzes gender equality in films that were nominated for, i.e. that won the Grand Golden Arena for best film at the Pula Film Festival in the period from 2010 to 2020, using methods of qualitative content analysis and narrative analysis. In order to find out whether there is gender inequality in the directing sector, but also in the content of the winning films, I analyzed individual depictions of female and male characters, the framework within which they’re shown and their relationships. In the analyzed films women are portrayed as support for the protagonist, although they are not always supporting characters. They are presented as submissive and passive; they are mothers, wives and daughters, determined solely by their relationship with men. Although they are the protagonists in some of the films, their actions are influenced by a man - the protagonist from the shadows. Men are portrayed as dominant, assertive, and emotionless; they are the embodiment of patriarchy. They initiate action directly or indirectly, although they are not always the protagonists. Patriarchy is not reflected in the big things in the films that the Pula Film Festival considered the most valuable in the analyzed period - these are small things that we as a society have so normalized that we ourselves unconsciously participate in them
