Irrigation, salinity and nitrogen (N) are the three major limiting environmental factors inmaize yield potentials especially in arid and semi-arid regions. An integrated water and N MaizeSimulation Model (MSM) was modified for salinity conditions using 2009-2010 fieldexperiments data in southwest of Iran. Irrigation levels were: I1=1.0ETc+0.25ETc as normalleaching amount, I2=0.75I1 and I3=0.5I1...

Nitrogen (N) uptake (kg ha-1) of field-grown potatoes was measured in 4.32 m2 lysimeters that were filled with coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for six weeks until final harvest. Results show...

Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...

A 45-year-old woman presented with a headache and visual complaints. Brain MRI revealed a large mass in the right occipital cortex. The tumor was surgically removed and pathological examination showed papillary carcinoma originating from thyroid gland. She had a history of thyroid surgery 27 years ago indicating papillary thyroid cancer with central neck lymph node involvement followed by no ad...

objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...

conclusions the results of the study show that tadalafil can increase the mean ielt and can be used for treatment of premature ejaculation in combination with paroxetine. results the mean age of patients in groups a and b were 33 ± 9.6 and 31.2 ± 9.3 years, respectively (p = 0.368). the mean number of intercourses were 1.08 ± 0.6 and 1.12 ± 0.6 per week in groups a and b, respectively (p = 0.79...

while the oecd test guidelines and mostly animal assays have been used to study the toxic effects of chemicals for many years, very little is known about the potential toxicity of vast majority of inhaled chemicals. considering large number of chemicals and complex mixtures present in indoor and outdoor air, heavy reliance on animal test methods appear to be not adequate. continuing scientific ...

Objective(s): To validate the reliability of nuclear medicine physicians in diagnosing lymphoma using positron emission tomography/computed tomography using 2-deoxy-2-[18F]fluoro-D-glucose (FDG-PET/CT) and to determine findings that reliably suggest lymphoma.Methods: Seventy patients suspected of having lymphoma using FDG-PET/CT were enrolled in this retrospective study. Two nuclear medicine ph...
