Understanding the soil-water dynamics and maize evapotranspiration (ETc) under variable rate irrigation (VRI) fertigation (VRF) management with respect to soil spatial variability constitutes basis for developing effective water nitrogen strategies. This long-term research was designed quantify compare dynamics, including available (AW), ETc during vegetative reproductive growth periods of VRI,...

The aim of this research was to determine the impact of voluntary information disclosure on informational content of share price. In this regard, future earnings response coefficient was used to determine the informational content of the share price about the future income information. Furthermore, share price synchronicity was used to evaluate the informational content of the share price about...

The metabolic activity of tendinous tissues has traditionally been considered to be of limited magnitude. However, recent studies have suggested that glucose uptake increases in the force-transmitting tissues as a response to contractile loading, which in turn indicates an elevated tissue metabolism. The purpose of the present study was to investigate whether such a mechanism could be observed ...

Aims. We present VRi photometric observations of the quadruply imaged quasar HE0435-1223, carried out with the Danish 1.54 m telescope at the La Silla Observatory. Our aim was to monitor and study the magnitudes and colors of each lensed component as a function of time. Methods. We monitored the object during two seasons (2008 and 2009) in the VRi spectral bands, and reduced the data with two i...

OBJECTIVE Internally guided actions are defined as being purposeful, self-generated and offering choices between alternatives. Intentional actions are essential to reach individual goals. In previous empirical studies, internally guided actions were predominantly related to functional responses in frontal and parietal areas. The aim of the present study was to distinguish event-related potentia...

An unresolved issue in the task-switching literature is whether preparatory reconfiguration occurs before a change of task. In this study, we used event-related potentials (ERPs) to determine whether preparatory reconfiguration occurs during two different task-switching procedures: voluntary and cued task switching.We focused on two ERP components that index different cognitive operations. The ...

Circadian rhythms are self-sustained 24-hour period oscillations present in most organisms, from bacteria to human. They can be synchronized to external cues, thus allowing organisms to anticipate environmental variations and optimize their performance in nature. In Drosophila, the molecular pacemaker consists of two interlocked transcriptional feedback loops. CLOCK/CYCLE (CLK/CYC) sits in the ...

OBJECTIVE To assess the clinical radiology research productivity in Pakistan by type of publication, sources of funding and name of journals. METHODS A systematic search strategy using key words related to techniques and type of clinical radiology was carried out to identify various studies published in Indexed (Medline) and non-indexed (Pakmedinet) medical journals. RESULTS Total of 397 st...
