The self-healing electrolytes play an essential role in supercapacitors. Herein, poly (vinyl alcohol)/sulphuric acid (PVA/H2SO4) hydrogel with properties are prepared, which has been achieved by dynamic hydrogen bonds between PVA chains. obtained displays fast capability, reliable mechanical performance (stress at 0.29 MPa after stretching to 238%) and high ionic conductivity (57.8 mS cm−1). Ba...

introduction: self-directed learning is originated from adult education which has currently gained a special place in educational systems and is influenced by many variables such as teaching self-efficacy and self-directed learning. this research investigated the relationship of teachers’ teaching with academic self-efficacy and self-directed learning from english language students' perspective...

Its highest form the Soviet, its 'lowest' the simple workplace representatives' committee, this formation rec...

nucleostemin (ns), a stem cell-abundant nucleolar protein, is critical for maintaining the self-renewal and proliferative properties of normal and cancerous stem cells. recent data suggests that ns signaling is important for proliferation of t-cells and leukemia cells. this study was conducted to verify the role of ns in pathogenesis and treatment of t-cell acute lymphocytic leukemia (t-all). o...
