the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...

Rice Diversity PIC SSR marker Diversity at molecular level among thirty rice genotypes, selected based on earliness and morphometric diversity was evaluated through five SSR markers associated with days to heading. Three primers viz., RM147, RM167 and RM215 showed polymorphism for growth duration related traits. A total of 17 alleles were detected among the 30 rice genotypes with an average of ...

This paper investigates thenotion of preemption in scheduling,with earliness and tardiness penalties. Starting from the observation that the classical cost model where penalties only depend on completion times does not capture the just-in-time philosophy, we introduce a new model where the earliness costs depend on the start times of the jobs. To solve this problem, we propose an efficient repr...

⎯In this paper, we consider the single machine earliness/tardiness scheduling problem with different release dates and no unforced idle time. The most effective lower bound uses multiplier adjustment procedures that require an initial sequence. We investigate the sensitivity of the lower bounding procedure to the initial sequences, and experiment with different scheduling rules and dominance co...

This paper presents the optimal sequence of a set of jobs for a single machine with idle insert, in which the objective function is to minimize the sum of maximum earliness and tardiness (n/1/I/ETmax). Since this problem tries to minimize and diminish the values of earliness and tardiness, the results can be useful for different production systems such as just in time (JIT). Special case of det...

this research in order to identify and introduction of  cotton  suitable cultivar  or cultivars for the double cropping of after wheat and canola harvesting  was carried out in the northern region of ardebil province. in this study, eight  varieties  of    imported cotton germplasm resources in recent years were chosen   and   with the iran's cultivars included  mehr  and varamin  were eva...

BACKGROUND AND PURPOSE The routine use of distal filter devices during carotid angioplasty and stent placement (CAS) is controversial. The aim of this study was to analyze their effects on the incidence of new diffusion-weighted imaging (DWI) lesions as surrogate markers for stroke in important subgroups. MATERIALS AND METHODS DWI was performed immediately before and after CAS in 68 patients ...
