The Demand for Base Money in Turkey : Implications for Inflation and Seigniorage

This paper presents estimates of the demand for money function derived from two alternative opportunity cost of holding money for the Turkish economy over the period 1988-2000. The specification of the equilibrium relationship is problematic in that real money balances are integrated of order one while the inflation rate and the depreciation of TL against US dollar are integrated of order zero. However it is possible to show that the logarithm of real money balances is stationary around a segmented linear time trend with a break in 1994. The parameter estimates obtained are used to investigate the inflation level and the extent to which real seigniorage revenues have been exploited within the Turkish economy.Money Demand, Seigniorage, Inflation

Parasal Analize Bir Bakis : Turkiye Ornegi

The primary goal of this study is to introduce monetary analysis for the Turkish economy in the light of empirical evidences that demonstrate the importance of this analysis for the economy. In the study we also focus on the implication of persistent money supply shocks, particularly shocks that are emanating from fiscal policies, on the Turkish economy by using a monetary disequilibrium model. Results show that if the government adopts a fiscal rule, as it is detailed in the study, instead of the current fiscal policies, then the Turkish economy attains a lower budget deficit, inflation and interest rates, but appreciated Turkish lira in the long-run. Additionally, this fiscal move may cause reductions in the real output growth in the short run, but the contractionary effects seem to be very limited over the long-run.Monetary aggregates, Monetary indicators, Monetary disequlibrium models, Fiscal rule

Ground defected planar super-wideband antenna: a suitable transceiver for short distance wireless communication

A planar microstrip patch super-wideband antenna is presented for short distance wireless communication applications. The antenna is comprised of a simple patch and a ground plane and etched on two sides of a 1.6 mm-thick standard FR4 substrate material with a relative permittivity of 4.5 and loss tangent (0.02). The proposed antenna possesses a compact size of 29 × 20.5 mm2 with an electrical dimension of 0.25 λ × 0.18 λ. To enhance the operating bandwidth, the ground plane is modified by adding seven small rectangular slots on its upper side. Through numerical studies, it is found that insertion of the slots enhances the coupling between the patch and ground plane resulting in achievement of a super-wide operating band. From the measurements, it is observed that the fabricated prototype antenna has a bandwidth from 2.63 to more than 18 GHz, a symmetric omnidirectional radiation characteristic and the maximum peak gain of 5.85 dBi which makes it a suitable transceiver for short distance communication applications

Numerical investigation of optimized piled raft foundation for high-rise building in Germany

Piled rafts have been used as a foundation system for high-rise buildings worldwide in different soil conditions, e.g., in soft to stiff clay as well as in medium-to-dense sand. Piled raft is currently used not only to control the foundation settlement but also to minimize the required raft thickness to reach the most optimized foundation design. The purpose of this study is to investigate the behavior of piled raft as a foundation system for Frankfurt over-consolidated clay based on the well-monitored Messeturm building in Germany. The numerical tool used in analysis is Plaxis 3D finite element software with hardening soil material model. The piled raft foundation behavior will be evaluated based on the total settlement, differential settlement and the pile skin friction. Based on this study, it was found that the chosen foundation system “plied raft foundation” for Messeturm was an optimized solution for the proposed building

Isolation and characterization of antineoplastic alkaloids from Catharanthus roseus l. Don. cultivated in Egypt

Vinblastine and vincristine (the antileukemic agents) were isolated, in a pure form, from Catharanthus roseus L. Don., cultivated in Egypt, by several chromatographic techniques. Five modified methods for the preparation of total alkaloids were carried out. All the isolated mixtures were evaluated by HPLC and HPTLC analyses. The antineoplastic alkaloids; vinblastine and vincristine, were isolated by the use of vacuum liquid chromatographic column on silica gel : aluminium oxide (1:1) mixed bed vacuum liquid chromatography (VLC), Charcoal column, and finally purified by centrifugally accelerated radial chromatography (Chromatotrone).Key words: Catharanthus roseus L., Apocyanaceae, Vinblastine, Vincrisitine, Antileuckemic alkaloids, VLC, HPLC, HPTL
