The steady-state activity of the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum (SR) is low when reconstituted into bilayers of the long-chain phosphatidylcholines dierucyl phosphatidylcholine [di(C22:1)PC] or dinervonyl phosphatidylcholine [di(C24:1)PC]. In di(C24:1)PC the ATPase binds a single Ca2+ ion, whereas in di(C22:1)PC it binds two, as in the native SR [Starling, East and Lee ...

Previous research has primarily examined the link between price, income, and consumer spending using linear regression models. On other hand, latest evidence shows an asymmetric among economic financial variables. We contribute to literature by employing a novel technique known as ARDL model. This approach is used investigate impact of favorable unfavorable changes in income prices on household...

The Texas citrus industry in the Rio Grande Valley experiences periodic droughts. During such times, water restrictions from the Amistad and Falcon Reservoirs can reduce water available for agriculture. Irrigation in this region is primarily surface waters from the Rio Grande where citrus orchards are flood irrigated. Irrigation practices that use less water are being explored and evaluated. ...

In today world of internet, it is important to feedback the users based on what they demand. Moreover, one of the important tasks in data mining is classification. Today, there are several classification techniques in order to solve the classification problems like Genetic Algorithm, Decision Tree, Bayesian and others. In this article, it is attempted to classify researchers to “Expert” and “No...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...

Tests of the null hypothesis of stationarity against the unit root alternative play an increasingly important role in empirical work in macroeconomics and in international finance. We show that the use of conventional asymptotic critical values for stationarity tests may cause extreme size distortions, if the model under the null hypothesis is highly persistent. This fact calls into question th...

One of the risks recognized by relevant authorities is the risk of outsourcing ITS projects. The purpose of this study was to design and explain the pattern of determining the critical success factors in outsourcing large-scale ITS projects in the Ministry of Roads and Urban Development (Road Maintenance and Transportation Organization). This study was performed using qualitative method. The pa...

1-Palmitoyl phosphatidylcholines (1-palmitoyl PCs), in which the 2-position was occupied respectively by C10:0, C12:0, C14:0, C14:1, n-7, C16:0, C16:1, n-7, C18:0, C18:1(t), n-9, C18:1, n-9, C18:2, n-6, C18:3, N-3, C18:3, n-6, C18:3(5t,9,12), C22:0, C22:1, n-9, C22:2, n-6, C22:3, n-3, C22:4, n-6, C22:5, n-6 or C22:6, n-3 fatty acids, were studied as monolayer films at the air/water interface. R...

In this article, we forecast crude oil and natural gas spot prices at a daily frequency based on two classification techniques: artificial neural networks (ANN) and support vector machines (SVM). As a benchmark, we utilize an autoregressive integrated moving average (ARIMA) specification. We evaluate outof-sample forecast based on encompassing tests and mean-squared prediction error (MSPE). We ...
