A poly（vinyl chloride）（PVC） membrane sensor for holmium ions was fabricated based on N-[（Z）-l-（2-thienyl）- methylidene]-N-[4-（4-{[（Z）-l-（2-thienyl）methylidene]amino} phenoxy）phenyl] amine （TPA） as a new ion carrier, acetophenon （AP） as plasticizing solvent mediator and sodium tetraphenyl borate （NaTPB） as an anion excluder. The electrode shows a good selectivity towards Ho^3＋ ions respect to other inorganic cations, including alkali, alka- line earth, transition and heavy metal ions. The constructed sensor displays a Nernstian behavior （19.5±0.3 mV/decade） over the concentration range of 1.0× 10^-6 to 1.0 ×10^- 2 mol·L^-1 with the detection limit of the electrode being 4.6）〈 10-7 mol·L^-1 and very short response time （ca. 5 s）. It has a useful working pH range of 3.2-9.8 for at least 8 weeks. The electrode was successfully applied as an indicator electrode for the potentiometric titration of a Ho^3＋ solution with EDTA and holmium determination in some alloys. The proposed sensor accuracy was studied by the determination of Ho^3＋ in mixtures of three different ions.

The dependencies of hydrocarbon product distributions of alkali promoted iron catalyst in Fischer-Tropsch synthesis have been studied. The concept of two superimposed Anderson-Schulz-Flory distributions has been applied for the representation of the effects of Mg, La and Ca promoters on product distributions. The FTS performance of the catalysts was tested in a fixed bed reactor under the conditions 563 K, 1.7 MPa, H2/CO = 1 and space velocities 4.86 and 13.28 nl·h^-1·gFe^-1. The results indicate that appropriate amounts of these promoters enhance the break in ASF distributions in the order Ca 〉 Mg 〉 La because of the rising of the catalyst surface basicity.

Immediately after an earthquake a healthcare system within a city, comprising several hospitals, endures an extraordinary demand. This paper proposes a new methodology to estimate whether the hospital network has enough capacity to withstand the emergency caused by an earthquake. The ability of healthcare facilities and to provide a broad spectrum of emergency services immediately after a seismic event is assessed through a metamodel that assumes waiting time as main response parameter to assess the hospital network performance. The First Aid network of San Francisco subjected to a 7.2 Mw magnitude earthquake has been used as case study. The total number of injuries and their distributions among the six major San Francisco’s Emergency Departments have been assessed and compared with their capacity that has been determined using a survey conducted by the medical staff of the hospitals. The numerical results have shown that three of the six considered San Francisco’s hospitals cannot provide emergency services to the estimated injured. Two alternatives have been proposed to improve the performance of the network. The fi rst one redistributes existing resources while the second one considers additional resources by designing a new Emergency Department.
