in this study, 3 models of time-varying parameters (tvp), dynamic model selection (dms) and dynamic model averaging (dma) and a comparison with the ordinary least squares (ols) method in matlab in the time period 2003-2013 (with data on a monthly basis) are discussed. in the present study, the variables of unofficial exchange rate changes, interest rate changes and inflation in oil price foreca...

The discussion started with 4 brief presentations which provided a theoretical background for the ensuing discussion. The presentations are posted and thus not much detail on the presentations is included here. (1) Anna Rutgersson presented the basic air-side theory of gas exchange. She discussed how young waves are found under high wind speeds. In laboratory studies, the drag coefficient level...

the interaction between nominal and real sectors is studied based on estimating a simultaneous co-integrated system including foreign and domestic prices, real output, liquidity and exchange rate variables. two co -integrating vectors namely augmented ppp and demand for money functions are identified. the results suggest that real output is a weakly exogeneous variable and relatively the leadin...

[1] We used a controlled-environment leaf gas-exchange system and the micrometeorological technique eddy covariance to determine whether circadian rhythms constrain the rates of leaf and canopy gas exchange in an Amazonian forest over a day. When exposed to continuous and constant light for 20 to 48 hours leaves of eleven of seventeen species reduced their photosynthetic rates and closed their ...

Gas exchange dynamics in insects is of fundamental importance to understanding evolved variation in breathing patterns, such as discontinuous gas exchange cycles (DGCs). Most insects do not rely solely on diffusion for the exchange of respiratory gases but may also make use of respiratory movements (active ventilation) to supplement gas exchange at rest. However, their temporal dynamics have no...

The present research aims to evaluate impacts of crude oil price return index, Bloomberg Petroleum Index and Bloomberg energy index on stock market returns of 121 companies listed in Tehran stock exchange in a 10 years' period from early 2006 to April 2016. First, explanatory variables were aligned with petroleum products index mostly due to application of dollar data. Subsequently, to check va...

This study was undertaken to improve our understanding of the mechanical properties of the respiratory system for a range of diving mammals to improve our ability to predict gas exchange during diving. Our long term aim is to determine the alveolar collapse depth and the pressure where gas exchange cease in marine mammals. We hypothesized that differences in the anatomy of the respiratory syste...

A mathematical model for thermal explosion in a combustible dusty gas containing fuel droplets with general Arrhenius reaction-rate laws, convective and radiative heat losses, and interphase heat exchange between gas and inert solid particles is investigated. The objective of the study is to examine the effects of interphase heat exchange between the gas and solid particles on i ignition of rea...

Rectal temperature (Tre) is often used to adjust measurements of blood gases, but these adjusted measurements may not approximate temperatures during intense exercise at main sites of gas exchange: muscle and lung. To evaluate differences in blood gases between sites, temperatures (T) were measured with thermocouples in the rectum (re), in mixed venous blood (v), in gluteal muscle (mu), and on ...
