In this paper we use the frequency domain Granger causality test of Breitung/Candelon (2006) to analyse short and long-run causality between energy prices and prices of food commodities. We find that the oil price Granger causes all the considered food prices. However, when controlling for business cycle fluctuations this link exists especially at low frequencies. Thus, short-run phenomena like...

t he objective of this study is using the markov switching vector autoregressive method and regime dependent impulse response functions to measure the pass-through of world food prices to consumer price index in iran from 1990 to 2013. with respect to information criteria and the log-likelihood ratio statistic, msia(2)-var(1) model has a better fit to data than other models. the magnitude of th...

This paper draws close connections between the ease of presenting a given complexity class C and the position of the index sets IC = f i : L(Mi) 2 C g and JC = f i : Mi is total ^ L(Mi) = 2 C g in the arithmetical hierarchy. For virtually all classes C studied in the literature, the lowest levels attainable are IC 2 P03 and JC 2 Q02; the rst holds i C is 02-presentable, and the second i C is re...

The Bush Hawk XP, which is produced by Found Aircraft of Canada, is a small, piston-engined utility transport aircraft suitable for bushplane operations. The original version was made in the 1960s, and it uses a sealed, plain hinged flap. In the latest production version the gross weight is increased substantially, necessitating an improved flap design to achieve better airfield distances and c...

To maximize the profitability of modern satellites, designers must invest their spacecraft with both capability and reliability. On-board, autonomous software holds the promise of greatly enhancing spacecraft abilities, yet software glitches have been directly to blame for recent, highly publicized failures. This paper presents the flightsoftware development framework created for the Generalize...

BACKGROUND Buparvaquone (BW 720C) is the major hydroxynaphtoquinone active against tropical theileriosis (Theileria annulata infection). Previous studies showed that buparvaquone, similarly to others hydroxynaphtoquinone, probably acts by binding to cytochrome b (cyt b) inhibiting the electron transport chain in the parasite. Several observations suggested that T. annulata is becoming resistant...
