magnetite (fe3o4) nanoparticles have been successfully prepared by a novel one-step and surfactant-free approach utilizing ferrous ion, as a single iron source. in this manner, the reaction occurs between two aqueous solutions via the spontaneous transfer of ammonia gas from one to another in room temperature. no ferric source or oxidizing specie, oxidation controlling and capping agents are ne...

Analysis how to use Internet influence to the process of political communication, marketing and the management of public relations, what kind of online communication methods are used by political parties, and to assess satisfaction, means of communication and the services they provide to their party's voters (people) and other interest groups and whether social networks can affect the political...

Exosomes play a crucial role in the crosstalk between cancer associated fibroblasts (CAFs) and cells, contributing to carcinogenesis tumour microenvironment. Recent studies have revealed that CAFs, normal cells all secrete exosomes contain miRNA, establishing cell-cell communication network within For example, miRNA dysregulation melanoma has been shown promote CAF activation via induction of e...

the objective of the present paper is to shed some light on peer feedback in efl writing courses. in recent years, with regard to teaching writing, there has been a total shift of approach, from product-orientation to process-orientation. a key component of the latter is peer assessment in which learners read each other's compositions and provide feedback to the writer, based on the teache...

researchers have suggested that interactional feedback which is between teacher and learner during their writing is associated with l2 learning because it prompts learners to notice l2 forms. this paper reports a classroom-based study that investigated the role of feedback in socio-cultural theory. in this study, 12 efl learners performed on three writing tasks and were provided with a three-st...

A robust surge of gonadotropin-releasing hormone (GnRH) release triggers the luteinizing hormone surge that induces ovulation. The GnRH surge is attributable to estradiol feedback, but the mechanisms are incompletely understood. Voltage-gated calcium channels (VGCCs) regulate hormone release and neuronal excitability, and may be part of the surge-generating mechanism. We examined VGCCs of GnRH ...

This paper focuses on the contributions a computer-mediated blended course can make for learning vocabulary in French as a Foreign Language (FFL). This course included class and on-line sessions, using Computer Mediated Communication (CMC) tools (forum and chat), for a written macro-task by French-learning Cypriot students accompanied in distance learning by FFL tutors. In the first part we pre...

Increase in intracellular superoxide anion level has been found to inhibit Fas-mediated apoptosis. However, not much has been studied on the relationship between intracellular superoxide and caspases. In response to incubation with TNF ligand over a period of time, caspases-2, -3, -8, and -9 activities of M14TF cells showed increasing caspase activity, meaning apoptosis was triggered. However, ...

Coaching caregivers of young children on the autism spectrum is a critical component parent-mediated interventions. Little information available about how providers implement parent coaching for in publicly funded early intervention systems. This study evaluated providers’ use an system. Twenty-five sessions were coded fidelity to established caregiver techniques. We found low techniques overal...

introduction: feedback cards are recommended as a feasible tool for structured written feedback delivery in clinical education while effectiveness of this tool on the medical students’ performance is still questionable. the purpose of this study was to compare the effects of structured written feedback by cards as well as verbal feedback versus verbal feedback alone on the clinical performance ...
