morphological and rapd markers were used to investigate the genetic diversity among 21 accessions of pomegranate originating from south eastern tunisia. thirteen morphological traits were studied and results showed significant differences for all morphological characters (p< 0.001). clustering based on fruit traits, using ward’s method, divided the accessions into three main groups. in rapd ana...
This paper proposed a multi-scale segmentation method for remote sensing image based on mathematical morphology. In mathematical morphological operations, opening transform can extract lighter connected components and closing transform can extract darker ones with size smaller than a given structure element in a gray image. A connected component, as an object, may have a high response to a give...
iron oxide (fe2o3) nanoparticles were synthesized by a simple approach using sodium borohydride (nabh4) and iron chloride hexahydrate (fecl3.6h2o). their physicochemical properties were characterized by high resolution transmission electron microscopy (hrtem), scanning electron microscopy (sem), x-ray diffraction (xrd) and electron dispersive spectroscopy (eds). xrd pattern showed that the iron...

learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
The present study aimed to investigate effects of the heavy metal Cd on the sperm morphological indices of Caspimyzon wagneri. The sperm were exposed to 0.01, 0.1, 1, 10, 100 and 1000 mg.L‑1 Cd for three minutes, three and 36 hours. The sperms exposed to Cd showed an increase in the length, width and surface of the head, flagella degradation and slightly flagella breakage. With increase of Cd ...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
