the aim to achieve in this study is to recover the cr(iii) and process waters used in thewastewaters of chrome tanning operation by membrane process during leather production. in the treatmentalternative contains, cartridge filter, nanofiltration (nf(np10)), nanofiltration nf(xn45) and reverse osmosisro(acm2) membranes. the raw chrome wastewater from the cartridge filter was given to nf(np10)me...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

• Porous copper oxide nanosheets grow in situ on nickel foam surface (NF). Removes low-concentration nitrate rapidly with almost no production. CuO/NF exhibits excellent stability and N 2 selectivity reduction. Electrochemical techniques have shown advantages for the removal of nitrate. Here, were grown self-supporting (NF) to prepare electrodes (CuO/NF), which realized rapid highly selective c...

Recently, three-dimensional nickel foam (3D-Nf) has been increasingly studied; however, further modifications in nanoscale surface modification are necessary for particular applications. In this work, hierarchically porous nanogranular NiS (NiS-3D-Nf) and wrinkle-shaped (w-NiS-3D-Nf) structures were fabricated directly on by a simple one-step solvothermal process using two different solvents. S...

آلیاژهای منیزیم معمولاً دارای عدم تقارن تسلیم در حالت کشش و فشار هستند که این عامل ناشی از سازوکارهای مختلف تغییر شکل پلاستیک فعال تحت بارگذاری‌های کششی فشاری است. مقاله بر روی شبیه‌سازی المان حجمی نماینده‌ی سه‌بعدی آلیاژ اکسترود شده تمرکز دارد تا با کمک روابط کریستال پلاستیسیته تأثیر شدت بافت پایه ـ را بررسی کند. پلاستیسته مبتنی‌بر لغزش به‌صورت یک زیربرنامه نرم‌افزار آباکوس (U‌M‌A‌T) برای آزمون...

introduction: evidence suggests that neuronal apoptosis in neurodegenerative diseases is correlated with inflammatory reactions. the beneficial or detrimental role of apoptosis in neuroinflammation is unclear. elucidating this question may be helpful in management of neurodegenerative diseases. since tnf-α is able to induce apoptosis as well as increased viability of the cells by activation of ...

Abstract Premise The HybPiper pipeline has become one of the most widely used tools for assembly target capture data phylogenomic analysis. After production locus sequences and before phylogenetic analysis, identification paralogs is a critical step ensuring accurate inference evolutionary relationships. Algorithmic approaches using gene tree topologies ortholog groups are computationally effic...

Recently neuro-inflammation and cognitive impairment has attracted attention. It has been suggested that obesity lead to cognitive impairments induced by neuro-inflammatory markers like nuclear factor kappa B (NF-kB) and reduced neurotrophin factors like brain-derived neurotrophic factor (BDNF) in the hippocampus. Also, increased blood brain barrier (BBB) permeability. Because of the neuro-prot...
