Repetitions, Their Phonetic Features And Functions In Kurmanji Kurdish

The study deals with the analysis of repetitions, their phonetic structures and functions as demonstrated in the organisation of talk-ininteraction in Kurdish. The repetitions are described as complex phonetic objects whose design has received no previous attention and are neglected by the scholars in the fields of discourse and conversation analysis studies in Kurdish. The main aims of the study are to identify the phonetic characteristics of repetitions in Kurdish, their functions and the relationship between differences in the phonetic features and their functions in speech. The study integrates the methodology of conversation analysis and impressionistic and instrumental phonetics to show how repetitions in a conversation are managed by the participants. The data used in this study comes from different types of natural speech, namely, face to face conversations, radio-phone-ins of Northern Kurdish. 27 cases of self repetitions have been analysed and they are lexical, phrasal and clausal with a range of syntactic forms. The study contributes to the theoretical issues of the prosody-pragmatics interface and participants’ understanding of naturally occurring discourse. It is hoped that such a study may contribute to language and information processing by providing a detailed analysis of patterns and functions of repetition in social interaction

Recent advances in electrospun fibrous membranes for effective chromium (VI) removal from water

The accumulation of heavy metals in aquatic environments is a significant environmental threat. Among the available methods for their removal, adsorption using nanofiber has been proven to be the most effective approach. The unique architecture of nanofibers provides them with intriguing features, such as high specific surface area and pore density, which makes them capable of removing harmful metals and a potential solution for various applications, including water treatment. This new generation of highly porous membranes is expected to have a promising future in separation applications due to its unique properties, including 90% porosity and 3D interconnected pore structure. Electrospinning is a well-regarded technique for creating such unique porous membranes. Among the various metal ions, chromium (Cr(VI)) removal has been extensively researched, and electrospun nanofiber membranes have proven to be an effective adsorbent. The objective of this review is to provide up-to-date information on the most common ways that electrospun nanofiber membranes are utilized for the removal of Cr(VI) ions from water. The findings indicate that electrospun fibrous materials are effective in eliminating Cr(VI) and establish their suitability for decontaminating polluted water. However, further attention is required to enhance the stability, mechanical strength, and reusability of these fibrous membranes
