AbstractAbstract
[en] In 1977, the Methodist Hospital of Lubbock, Texas, sold a 14 year old Picker C-3000 therapy unit to Mexican Centro de Juarez, instead of taking up the Picker option of dismantling, removal and safe storage. The device was never used for research or treatment, and the resulting accident after its dismantling and dispersion of the parts by unknown persons in November 1983 is described in outline. (U.K.)

AbstractAbstract
[en] An overview is presented of the Mexican petroleum sector. The sector is largely controlled by the state company PEMEX and is not completely open to foreign participation and supply, however the trend towards privatization and open competition, combined with the drive for competitiveness of PEMEX operations in particular, is creating market opportunities for foreign suppliers of petroleum equipment and services. Detailed profiles are provided of 50 Mexican companies and their primary products and services, specific areas of expertise, client base, international experience, interest in Canada, other relevant information, and a contact person. A less detailed list is also provided of additional Mexican contacts, petroleum industry associations and chambers of commerce

AbstractAbstract
[en] The composition and abundance of phytoplankton community, and its relation to physical and chemical factors was evaluated in the fluvial-lagoon systems Pom-Atasta (PA) and Palizada del Este (PE), in February, 2011. Water samples were collected in ten sampling sites in each lagoon, with a van Dorn bottle at the surface and in the middle of the water column to measure temperature, salinity, dissolved oxygen, inorganic nutrients, chlorophyll a and the composition and abundance of phytoplankton. In order to describe the behavior of phytoplankton it was calculated species abundance, Shannon-Wiener diversity and Pielou equitability indices were used, and to analyze the relationship between the abundance of phytoplankton species and environmental variables, a canonical correspondence analysis (CCA) was applied. The results showed that PE was the lagoon that presented a great biodiversity with 348 identified taxa, maximum abundance values (269 X 103 cells L-1), H' (3.2) and J' (0.95). Cylindrotheca closterium was the most abundant species in both systems, observing the highest abundance (52.5 X 103 cells L-1) in PA, forming incipient toxic algal blooms. It should be noted that salinity was the most influential environmental variable in the composition and abundance of phytoplankton.

AbstractAbstract
[en] Cyanobacteria inhabit hypersaline, marine and freshwater environments. Some toxic and non-toxic species can form harmful blooms. The aim of this study was to identify potentially harmful cyanobacterial species in the oyster banks of Terminos Lagoon, the southeastern Gulf of Mexico. Six sample sites (up to 2-m depth) were monitored monthly from August 2012 to September 2013. Water temperature, salinity, pH, dissolved oxygen saturation (% DO), inorganic nutrients and abundance of cyanobacteria were determined. Temperature and salinity were characterized by marked seasonal differences (26.8 to 30.6 Celsius degrade and 6.1 to 19.5, respectively). The pH values (ranging from 7.1 to 8.4) and the % DO (88.4 to 118.2 %) suggest a predominance of photosynthetic activity in the windy season (October-February). Elevated nutrient contents are associated with the period of increased river discharge, determined by water circulation and biogeochemical processes. Fourteen taxa were identified, of which Anabaena sp., Merismopedia sp., Oscillatoria sp. and Cylindrospermopsis cuspis produced blooms. Cyanobacterial abundances were on the order of magnitude of 106 cells L-1 in October 2012 at stations S1-S6, with an average value of 3.2x105 cells L-1 and a range of 2000 to 3.1x106 cells L-1 throughout the study period; however, they showed a remarkable absence during the windy season (October to January). Anabaena sp. and C. cuspis reached abundances of 1.9x106 and 1.3x106 cells L1, respectively. The latter caused the temporary closure of oyster Crassostrea virginica harvesting for 15 days in October 2012.

AbstractAbstract
[en] Complete text of publication follows. In this paper we introduced a methodology, measurements, and results obtained from two campaigns conducted on December 2008 and February 2009, making a total of 16 of the 52 repeat magnetic network stations existing in Mexico, for Mexico Magnetic Chart Epoch 2010.0. The last magnetic chart in Mexico was issued in the 90's by Magnetic Survey of Geophysics Institute-UNAM. We took over the recuperation of lost measurements that had been left over at lack of money and human resources. In 2009 the Magnetic Survey was included inside SIBA (Environmental and Biodiversity Informatics System) project. Founds were approved and then we could start getting to work for magnetic chart survey with at least two complete magnetic network reoccupations. At the fist 16 stations (that had been all ready made up till now) we got a lot of problems. But the main one was the lost or destroyed over of original marks measured in 90's and it was hard too finding a new good place for replacing these sites. Observed measurements in these sites shown satisfactory records inside the expected rate. In 2009 we will be able to carry out three more campaigns to measure 24 more stations having a total of 40 by the end year. During 2010 and 2011 we will complete the survey to finish the whole magnetic chart for epoch 2010.0.
