The concept of "spectrum" in Jacques Derrida's philosophy of exclusion and evocation

This research is an interpretive and critical approach to one of Jacques Derrida's theories of deconstructive philosophy, the term "spectrum", which focuses first on trying to define and clarify the meanings that can be contained within Derrida's texts, and then sheds light on its location and importance for the School of Methodological Practice , And in a third stage, this paper presents an illustration of Derrida's divergence regarding the concept of the spectrum that this argument indicates between exclusion and retention and how Derrida's position can be interpreted in this regard. Finally, this research presents a critical approach to the functional role of Derrida's philosophy .

Creating Sign and reading strategy in the deconstructing critism of Derrid

This research attempts at focusing on the sing concept by the French philosopher Jacques Derrida and how he tried to present a different critical reading of this concept, busy answering the question and looking for new horizons of this critical reading that gose beyond the structural closure. this will be through a reading strategy that enables us to open up to the text and its multiplicities. So this research firstly introduces the concept as done by Derrida then proceeds to discuss the role of reader being one deadly strategy in creating or producing the sing, being one product of the text, and his ability to recall the memory. All of this is to clarify the distance among texts which the textual horizon creates, since its role dose not have to do only with the strength of sing as in difference but also it contains a structural motive.The sign is created once the effect and the one who is put away are traced down and thus creates enterainment among texts. Consequently, reading becomes an aesthetic experience that reconstructs the text anew till we get in this research to accumulative results in a conclusion that presents some of the ideas we ended up with when tacking this issue.

Optimization of Lignocellulosic Material Degrading Enzymes Producing by Syrian Nَative Aquatic Actinobacteria Strains

After morphological and biochemical studies, 11 strains of Actinobacteria were isolated, mostly of them belong to the genus Streptomyces, these strains were used later to detect their ability in cellulase and xylanase enzymes production during the initial detection depending on the diameter of the halo transparent around cultured colonies on solid media.
