The serum of foxes and red deer from the Province of Soria (northern Spain) was screened in indirect immunofluorescence assays to determine whether these animals could be used as sentinels of the tick-borne pathogens Anaplasma phagocytophilum and Ehrlichia chaffeensis. The results suggest that foxes and red deer would not make good sentinels in epidemiological studies on E. chaffeensis in this region, although red deer could be used as such for the study of A. phagocytophilum transmission.

This study analyzes six vegetation communities in relation to current climatic parameters and eight climate change scenarios along an elevation gradient extending from 2,710 m to 4,210 m in the Trans-Mexican Volcanic Belt. The projected movements of 25 plant species with the current restricted or wide altitudinal distributions were also modeled. To relate climatic parameters to the species and communities, a Precipitation/Temperature （P/T） index was used both for the current and the different climate-change scenarios. The temperatures are expected to increase by 1.1℃ to 1.7℃ by 2020 and by 2℃ to 3℃ by 2o5o. A decrease of 4% to 13% in the annual precipitation is expected for the 2020 horizon, and a reduction between 3% and 20% is expected for 2050. The reductions in water availability were projected for all altitude levels and plant communities. The most marked reduction was under the HADLEY- A2 scenario, in which the lower limit of the altitudinal range increased from 2,71o to 3,31o m （2050 horizon） with reductions in the P/T index between 36% and 39% compared to the current climate. Most plant species tended to shift their distribution from 20o to 300 m upward in the 2020 temporal horizon scenarios. The Pinus hartwegii, Alnus jorullensis and Pinus montezumae communities would have a shorter altitudinal range as they move upward and merge with the remaining species at the higher altitudinal range. For the 2o5o temporal horizon, 3o% of the species, primarily those from the higher altitudinal range, would disappear because their P/Tindex values would be above the limit of plant survival （〉4,210 m）.

The Cuban people are made up of three major migratory currents, the Chinese are one of them. They brought their culture, the methods, and procedures of traditional Chinese medicine(TCM) in the 19th century. Few were able to return and so they created families in Cuba;some of their descendants dedicated themselves to medicine. In order to investigate the practices that were predecessors of TCM in Cuba in the 19th century, a qualitative phenomenological research was carried out, reviewing what was published by various sources, applying documentary analysis, logical historical analysis, abstraction, synthesis, and systematization of the results on the regularities of the work and human behavior of Chinese doctors in the Cuban 19th and 20th centuries. This made it possible to identify six Chinese doctors in the 19th century in Cuba who gave rise to the beginning of some practices of TCM in Cuba, and five from the 20th century, descendants of coolies who dedicated themselves to other specialties of medicine. It was found that despite their geographical and time disperse, they were all notorious for their outstanding professional and human behavior, with a trail of accumulated successes in achieving “almost the impossible” with the patient. They have left their mark on Cuban culture.

The steam reforming of glycerol has been studied at 500 and 600 oC using Co/SBA-15 and Co/M/SBA-15（M: Zr, Ce, or La） promoted catalysts. The prepared materials were characterized by inductively coupled plasma atomic emission spectroscopy（ICP-AES）, X-ray powder diffraction（XRD）, hydrogen temperatureprogramed reduction（H;-TPR）, ammonia temperature-programed desorption（NH;-TPD）, nitrogen physisorption analysis（N;-BET）, transmission electron microscopy（TEM） and thermogravimetric analysis（TGA）. The incorporation of promoters like Zr, Ce and La on SBA-15 support and successive Co impregnation leaded to smaller cobalt crystallites improving metaldispersion. Besides, stronger metal-support interactions between Co species and M/SBA-15 supports were observed. Thanks to the incorporation of Zr, La and mainly Ce, promoted catalysts present higher glycerol conversion than Co/SBA-15 along 5 h of time on stream. Besides, at 600 oC, Co/M/SBA-15（M: Zr, Ce, or La） catalysts produce higher hydrogen amounts than Co/SBA-15.

The adsorption of Mn2＋ onto immobilized Mn-oxide and Fe-oxide adsorbent such as manganese oxide-coated sand 1 （MOCS1）, manganese oxide-coated sand2 （MOCS2）, iron oxide-coated sand2 （IOCS2）, and manganese and iron oxide-coated sand （MIOCS）was investigated. The effects of pH （5.5 to 8.0） and temperature （25 to45°C） on the equilibrium capacitywere examined. Equilibrium studies showed that there is a good fitwith both Freundlich and Langmuir isotherm,which indicates surface heterogeneity and monolayer adsorption of the adsorbents. Kineticdata showed high correlationwith the pseudo second-order model,which signifies a chemisorption-controlled mechanism. The activation energies, activation parameters （ΔG＊,ΔH＊,ΔS＊）, and thermodynamic parameters （ΔG0 , ΔH0 , ΔS0 ） confirmed that adsorptionwith MIOCSwas endothermic and more spontaneous at higher temperaturewhile an opposite trendwas observed for the other adsorbents. Thermodynamic studies showed that adsorption involved formation of activated complex,where MOCS1 and MIOCS follow a physical-chemical mechanism,while MOCS2 and IOCS2 follows purely chemical mechanism.
