Simulation studies on metastable phase equilibria in the aqueous ternary systems (NaCl-MgCl

Tianlong DENG, Baojun ZHANG, Dongchan LI, Yafei GUO

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 172-175 doi: 10.1007/s11705-009-0048-1

Abstract: The solubilities and densities of the aqueous metastable ternary systems (NaCl-MgCl -H O) and (KCl-MgCl -H O) at 308.15 K were determined by the isothermal evaporation method. On the basis of the experimental results, the phase diagrams for those systems were plotted. It was found that the former system belongs to the hydrate-I type with one invariant point of (NaCl+ MgCl ?6H O), two univariant curves, and two crystallization regions corresponding to halite (NaCl) and bischofite (MgCl ·6H O); and the latter system belongs to the type of incongruent-double salts with two invariant points of (KCl+ KCl·MgCl ·6H O) and (MgCl ·6H O+ KCl·MgCl ·6H O), three univariant curves, and three crystallization regions corresponding to potassium chloride (KCl), carnallite (KCl·MgCl ·6H O) and bischofite (MgCl ·6H O). No solid solutions were found in both systems.

Genomic and pharmacogenetic studies of childhood acute lymphoblastic leukemia

Ching-Hon Pui

Frontiers of Medicine 2015, Volume 9, Issue 1,   Pages 1-9 doi: 10.1007/s11684-015-0381-3

Abstract:

With the cure rate of childhood acute lymphoblastic leukemia (ALL) approaching 90%, further improvement in the treatment outcome and quality of life of patients will require better understanding of the mechanisms of drug resistance, identifying new leukemic cell genetic lesions that are amendable to available target therapy, and optimizing treatment based on host pharmacodynamics and pharmacogenomics. Deeper characterization of leukemic cell genetic abnormalities has discovered new subtypes of leukemia such as early T-cell precursor ALL and Philadelphia chromosome-like ALL, and identified many genomic alterations that have diagnostic, prognostic, or therapeutic implications. In this regard, several novel fusion transcripts are responsive to ABL tyrosine kinase inhibitors and potentially to JAK inhibitors. Genome-wide analyses have also unraveled the role of inherited cancer predisposing genes and small nucleotide polymorphisms of several genes in the development of childhood ALL. These advances promise to lead to more sophisticated personalized treatment strategies in the near future.

Optimization, Kinetics, and Equilibrium Studies on the Removal of Lead(II) from an Aqueous Solution Using Article

Shridhar S. Bagali, Bychapur S. Gowrishankar, Aashis S. Roy

Engineering 2017, Volume 3, Issue 3,   Pages 409-415 doi: 10.1016/J.ENG.2017.03.024

Abstract:

Natural adsorbents such as banana pseudostem can play a vital role in the removal of heavy metal elements from wastewater. Major water resources and chemical industries have been encountering difficulties in removing heavy metal elements using available conventional methods. This work demonstrates the potential to treat various effluents utilizing natural materials. A characterization of banana pseudostem powder was performed using environmental scanning electron microscopy (ESEM) and Fourier-transform infrared (FTIR) spectroscopy before and after the adsorption of lead(II). Experiments were carried out using a batch process for the removal of lead(II) from an aqueous solution. The effects of the adsorption kinetics were studied by altering various parameters such as initial pH, adsorbent dosage, initial lead ion concentration, and contact time. The results show that the point of zero charge (PZC) for the banana pseudostem powder was achieved at a pH of 5.5. The experimental data were analyzed using isotherm and kinetic models. The adsorption of lead(II) onto banana pseudostem powder was fitted using the Langmuir adsorption isotherm. The adsorption capacity was found to be 34.21 mg·g−1, and the pseudo second-order kinetic model showed the best fit. The optimum conditions were found using response surface methodology. The maximum removal was found to be 89%.

Parameter studies on impact in a lap joint

Amir M. RAHMANI,Elizabeth K. ERVIN

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 1,   Pages 64-77 doi: 10.1007/s11465-014-0322-x

Abstract:

To represent a loose lap joint, a beam impacting four springs with gaps is modeled. Modal analysis with base excitation is solved, and time histories of contact points are closely monitored. Using the impulse during steady state response, six influential parameters are studied: damping ratio, contact stiffness, intermediate contact position, gap, excitation amplitude and beam height. For all parameters, the system response is highly controlled by modes with two contacting springs. Each parameter’s effect on system response is presented including unstable regions, unique trend behaviours result. Recommendations for structural designers are also noted.

Experimental studies on the influence of porosity on membrane absorption process

GAO Jian, REN Zhongqi, ZHANG Zeting, ZHANG Weidong

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 4,   Pages 385-389 doi: 10.1007/s11705-007-0070-0

Abstract: Eight kinds of flat membranes with different micro-structures were chosen to carry out the membrane absorption experiments with CO and de-ionized water or 0.1 mol · L NaOH solution as the experimental system. According to experimental results, the membrane pores shape (stretched pore and cylinder pore) and membrane thickness do not affect the membrane absorption process, and the membrane porosity has only little influence on membrane absorption process for slow mass transfer system. However, the influence of porosity on the membrane absorption process became visible for fast mass transfer system. Moreover, the mass transfer behavior near the membrane surface on liquid side was studied. The results show that the influence of membrane porosity on mass transfer relates to flow condition, absorption system and distance between micro-pores, etc.
