Full Text Available Advanced backcrosses (ABs and introgression lines (ILs of eggplant (Solanum melongena can speed up genetics and genomics studies and breeding in this crop. We have developed the first full set of ABs and ILs in eggplant using Solanum incanum, a wild eggplant that has a relatively high tolerance to drought, as a donor parent. The development of these ABs and IL eggplant populations had a low efficiency in the early stages, because of the lack of molecular markers and genomic tools. However, this dramatically improved after performing genotyping-by-sequencing in the first round of selfing, followed by high-resolution-melting single nucleotide polymorphism genotyping in subsequent selection steps. A set of 73 selected ABs covered 99% of the S. incanum genome, while 25 fixed immortal ILs, each carrying a single introgressed fragment in homozygosis, altogether spanned 61.7% of the S. incanum genome. The introgressed size fragment in the ILs contained between 0.1 and 10.9% of the S. incanum genome, with a mean value of 4.3%. Sixty-eight candidate genes involved in drought tolerance were identified in the set of ILs. This first set of ABs and ILs of eggplant will be extremely useful for the genetic dissection of traits of interest for eggplant, and represents an elite material for introduction into the breeding pipelines for developing new eggplant cultivars adapted to the challenges posed by the climate-change scenario.

Parthenium weed is a highly invasive alien species in more than 40 countries around the world. Along with severe negative effects on human and animal health and crop production, it also causes harm to ecosystem functioning by reducing the native plant species biodiversity. However, its impacts on native plant species, especially in pasture communities, are less known. Given parthenium weed causes substantial losses to Australian pastures' productivity, it is crucial to estimate its impact on pasture communities. This study evaluates the impact of parthenium weed upon species diversity in a pasture community at Kilcoy, south east Queensland, Australia. Sub-sites containing three levels of parthenium weed density (i.e. high, low and zero) were chosen to quantify the above- and below-ground plant community structure. Species richness, diversity and evenness were all found to be significantly reduced as the density of parthenium weed increased; an effect was evident even when parthenium weed was present at relatively low densities (i.e. two plants m -2 ). This trend was observed in the summer season as well as in winter season when this annual weed was absent from the above-ground plant community. This demonstrates the strong impact that parthenium weed has upon the community composition and functioning throughout the year. It also shows the long-term impact of parthenium weed on the soil seed bank where it had displaced several native species. So, management options used for parthenium weed should also consider the reduction of parthenium weed seed bank along with controlling its above-ground populations.

Full Text Available Parthenium plants and neem leaves were composted using the epigeic earthworm, Eisenia fetida (worm-worked compost to study the growth and reproductive indices of earthworm involved in the process of composting. Similarly, parthenium plants and neem leaves were composted without worms (worm-unworked compost. Efficacy of the resulting composts in supporting the growth of plant was tested with the germination and growth of Vigna radiate seedlings. The results showed that higher parthenium amendment significantly reduced the growth and reproduction of Eisenia fetida compared with control. The two-way ANOVA results showed a significant difference in the growth rate of worms when exposed to different amended concentrations of parthenium plants and neem leaves at different durations as fixed factors. The following compost parameters were not significantly different when compared with control: pH, nitrogen, phosphorus, iron for parthenium worm-worked compost; nitrogen, phosphorus, magnesium, iron, organic carbon and carbon/nitrogen ratio for neem worm-worked compost; nitrogen, phosphorus and organic carbon for parthenium worm-unworked compost and pH, nitrogen, phosphorus, zinc and carbon/nitrogen ratio for neem worm-unworked compost. Between parthenium plant composts and neem leaves composts, significant differences were not observed in any of the plant biometric parameters. The results obtained from the present study indicated that the parthenium composting at low amendments with cow dung may help its eradication for better utilization.

Prosopis juliflora and Parthenium hysterophorus are the two arid, exotic weeds of India that are characterized by distinct, profuse growth even in nutritionally poor soils and environmentally stressed conditions. Owing to the exceptional growth nature of these two plants, they are believed to harbor some novel bacterial communities with wide adaptability in their rhizosphere. Hence, in the present study, the bacterial communities associated with the rhizosphere of Prosopis and Parthenium were characterized by clonal 16S rRNA gene sequence analysis. The culturable microbial counts in the rhizosphere of these two plants were higher than bulk soils, possibly influenced by the root exudates of these two plants. The phylogenetic analysis of V1_V2 domains of the 16S rRNA gene indicated a wider range of bacterial communities present in the rhizosphere of these two plants than in bulk soils and the predominant genera included Acidobacteria, Gammaproteobacteria, and Bacteriodetes in the rhizosphere of Prosopis, and Acidobacteria, Betaproteobacteria, and Nitrospirae in the Parthenium rhizosphere. The diversity of bacterial communities was more pronounced in the Parthenium rhizosphere than in the Prosopis rhizosphere. This culture-independent bacterial analysis offered extensive possibilities of unraveling novel microbes in the rhizospheres of Prosopis and Parthenium with genes for diverse functions, which could be exploited for nutrient transformation and stress tolerance in cultivated crops.

Full Text Available This work aimed to evaluate the symbiotic compatibility and nodulation efficiency of rhizobia isolated from Desmodium incanum, Lotus corniculatus, L. subbiflorus, L. uliginosus and L. glaber plants by cross-inoculation. Twelve reference strains and 21 native isolates of rhizobia were genetically analyzed by the BOX-PCR technique, which showed a high genetic diversity among the rhizobia studied. The isolates were also characterized based on their production of indolic compounds and siderophores, as well as on their tolerance to salinity. Fifteen of the 33 rhizobia analyzed were able to produce indolic compounds, whereas 13 produced siderophores. All the tested rhizobia were sensitive to high salinity, although some were able to grow in solutions of up to 2% NaCl. Most of the native rhizobia isolated from L. uliginosus were able to induce nodulation in all plant species studied. In a greenhouse experiment using both D. incanum and L. corniculatus plants, the rhizobia isolate UFRGS Lu2 promoted the greatest plant growth. The results demonstrate that there are native rhizobia in the soils of southern Brazil that have low host specificity and are able to induce nodulation and form active nodules in several plant species.

To assess the pattern of cross-sensitivity between 4 members of the Compositae family, namely Parthenium hysterophorus L., Xanthium strumarium L., Helanthus annuus L. and Chrysanthemum coronarium L., 63 patients clinically diagnosed to have airborne contact dermatitis, and 51 controls having well-defined patterns of contact dermatitis caused by agents other than plants, were patch tested with measured amounts of standardized aqueous extracts of these plants. Positive reactions were obtained in 62 patients and 13 controls with Parthenium hysterophorus, in 47 patients and 9 controls with Xanthium strumarium, in 7 patients and 2 controls with Helianthus annuus, and in 13 of the 57 patients and one out of 28 controls tested with Chrysanthemum coronarium. 2 patients were allergic to all 4 of the plants; 14 patients to 3 plants, namely Parthenium, Xanthium and Chrysanthemum in 9 cases and Parthenium, Xanthium and Helianthus in 5 cases; 32 patients to 2 plants, namely Parthenium and Xanthium in 30 cases, and Parthenium and Chrysanthemum, and Xanthium and Chrysanthemum in 1 case each; 15 patients were allergic to 1 plant only, that being Parthenium. All the 47 patients allergic to Xanthium, 13 patients allergic to Chrysanthemum and 7 patients allergic to Helianthus were positive with some other plant as well. There was 1 patient who was allergic to Xanthium and Chrysanthemum but not to Parthenium. The titre of contact hypersensitivity (TCH) determined in the patients allergic to Parthenium, Xanthium and Helianthus showed values that varied widely with each plant in different patients, and there was no parallelism between the TCH with various plants.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available A 60-year old man living in Srinagar (Jammu and Kashmir had air-borne contact dermatitis for last 10 years. He had never traveled to any other part of the country where Parthenium hysterophorus or Xanthium strumarium are prevalent but he used to cultivate chrysanthemums. Patch tests with standardized extracts of various plants revealed the strongest reaction with Chrysanthemum, while the reactions with Xanthium strumarium and Parthenium hysterophorus were also positive but milder. This seems to be a case of primary sensitivity to Chrysanthemum with cross sensitivity to Xanthium strumarium and Parthenium hysterophorus.

Search for less-toxic radioprotectors has spurred interest in the development of natural products. In Ayurveda, the traditional medicine, Tanacetum species have been used to treat ailments since ancient times throughout the world. Effects of the administration of different concentrations of Tanacetum parthenium leaf aqueous extract (TPLA), Tanacetum parthenium leaf ethanolic extract (TPLE) were investigated in Swiss albino mice. Mice (20-25 g) were randomly divided into 8 groups of ten animals each. The control group and the radiation group were treated daily with oral administration of saline for 15 days. Each subgroups of TPLA and TPLE were treated with doses of 50, 100 and 250 mg/kg daily for 15 days. On the 15th day, all were irradiated with 10 Gy whole body irradiation. Survival was observed daily up to 30th post-irradiation day. Data were analysed using the Kaplan-Meier survival curves. The significance difference in survival between control, radiation and treatment groups were observed (P < 0.001). Current studies revealed the protective effect of Tanacetum parthenium rendering high survivability in lethally irradiated mice. (author)

Full Text Available The issue of Parthenium hysterophorus weed is very important in Ethiopian agriculture. It is spreading rapidly in the highland and lowland areas since its introduction. Currently, most of the regions are invaded by the weed, even the capital city Addis Ababa. There are several factors favoring its rapid distribution in the environment. Its ability to adapt wide range of climatic condition, its allelopathic effect,  short life cycle, prolific nature and having large seed bank in the soil environment are among the principal factors. Parthenium has the capacity to decrease the composition and diversity of plant species and it has adverse effects on crop yield, as well as animal and human health. Despite its negative effects, the weed has potential uses such as preparing compost, botanical control of insect pests and bio-herbicide. On the other hand, mechanical control, chemical herbicides, phytochemicals, composting and biological control has been pointed out as an effective management ways and eradication of this weed. There is a need for ecologically balanced management of Parthenium weed aiming to enhance the quality of life for farmers and rural communities, especially in pastoral and agro-pastoral areas of Ethiopia. Hence, the objective of this review was to explore the distribution, harmful and beneficial effects as well as the possible controlling practices against P. hysterophorus.

Modification of induced genetic damage after exposure to LD 50 and LD 90 doses of 60 Co gamma-irradiation on dormant seeds of Solanum incanum L. by pre- and post-treatments of thiourea was investigated. Thiourea pre-treatment reduced cellular lesions, growth injury and the death of seedlings, while post-treatment increased lethality. Incorporation of 3 H-tymidine into DNA fraction gradually increased with 10 -4 to 10 -2 M thiourea treatment when applied before irradiation. Post-treatment of the thiourea, on the other hand, not only showed poor labelling of DNA but also delayed its synthesis. (author)

The present study was carried out to investigate the phytotoxic effect of aqueous leaf extracts of two eucalyptus species viz. E citriodora Hook and E. camaldulensis Dehnh. Against the germination and seeding growth of alien aggressive weed parthenium hysterophorus L. The experiment was conducted in department of Mycology and plant Pathology in 2006. Aqueous leaf extracts of 2, 4, 6, 8 and 10% (w/v) of the two aforementioned Eucalyptus species were employed in the present study. Extracts of 2-8% concentration of both the Eucalyptus species significantly suppressed germination of the target weed species. A 10% extract of both the species completely arrested the germination. Aqueous extracts also reduced the root and shoot length of parthenium. Effect of extracts on seedling biomass was insignificant. (author)

Full Text Available A kinetic study of pyrolysis process of Parthenium hysterophorous is carried out by using thermogravimetric analysis (TGA equipment. The present study investigates the thermal degradation and determination of the kinetic parameters such as activation E and the frequency factor A using model-free methods given by Flynn Wall and Ozawa (FWO, Kissinger-Akahira-Sonuse (KAS and Kissinger, and model-fitting (Coats Redfern. The results derived from thermal decomposition process demarcate decomposition of Parthenium hysterophorous among the three main stages, such as dehydration, active and passive pyrolysis. It is shown through DTG thermograms that the increase in the heating rate caused temperature peaks at maximum weight loss rate to shift towards higher temperature regime. The results are compared with Coats Redfern (Integral method and experimental results have shown that values of kinetic parameters obtained from model-free methods are in good agreement. Whereas the results obtained through Coats Redfern model at different heating rates are not promising, however, the diffusion models provided the good fitting with the experimental data.

2015-01-01

Full Text Available Background: Azathioprine in daily doses has been shown to be effective and safe in the treatment of Parthenium dermatitis. Weekly pulses of azathioprine (WAP are also effective, but there are no reports comparing the effectiveness and safety of these two regimens in this condition. Aims: To study the efficacy and safety of WAP and daily azathioprine in Parthenium dermatitis. Methods: Sixty patients with Parthenium dermatitis were randomly assigned to treatment with azathioprine 300 mg weekly pulse or azathioprine 100 mg daily for 6 months. Patients were evaluated every month to assess the response to treatment and side effects. Results: The study included 32 patients in the weekly azathioprine group and 28 in the daily azathioprine group, of whom 25 and 22 patients respectively completed the study. Twenty-three (92% patients on WAP and 21 (96% on daily azathioprine had a good or excellent response. The mean pretreatment clinical severity score decreased from 26.4 ± 14.5 to 4.7 ± 5.1 in the WAP group, and from 36.1 ± 18.1 to 5.7 ± 6.0 in the daily azathioprine group, which was statistically significant and comparable (P = 0.366. Patients on WAP had a higher incidence of adverse effects (P = 0.02. Limitations: The study had a small sample size and the amount of clobetasol propionate used in each patient was not determined, though it may not have affected the study outcome due to its comparable use in both groups. Conclusions: Azathioprine 300 mg weekly pulse and 100 mg daily dose are equally effective and safe in the treatment of Parthenium dermatitis.

This study is aimed at assessing culturable diazotrophic bacterial diversity in the rhizosphere of Prosopis juliflora and Parthenium hysterophorus, which grow profusely in nutritionally-poor soils and environmentally-stress conditions so as to identify some novel strains for bioinoculant technology. Diazotrophic isolates from Prosopis and Parthenium rhizosphere were characterized for nitrogenase activity by Acetylene Reduction Assay (ARA) and 16S rRNA gene sequencing. Further, the culture-independent quantitative PCR (qPCR) was performed to compare the abundance of diazotrophs in rhizosphere with bulk soils. The proportion of diazotrophs in total heterotrophs was higher in rhizosphere than bulk soils and 32 putative diazotrophs from rhizosphere of two plants were identified by nifH gene amplification. The ARA activity of the isolates ranged from 40 to 95 nmol ethylene h(-1) mg protein(-1). The 16S rRNA gene analysis identified the isolates to be members of alpha, beta and gamma Proteobacteria and firmicutes. The qPCR assay also confirmed that abundance of nif gene in rhizosphere of these two plants was 10-fold higher than bulk soil.

Silver nanoparticles were prepared through eco-friendly, cost effective, bio-mediated technique using anaerobically digested Parthenium hysterophorous digested slurry (PDS) for the first time. The synthesized nanoparticles were characterized through different techniques such as UV-Vis spectrophotometer for optical properties; X-ray diffractometer (XRD), high resolution transmission electron spectroscopy (HR-TEM) and Fourier Transform Infra Red (FTIR) Spectroscopy for structural property investigations. It was observed that the prepared silver nanoparticles were crystallized in face centered cubic crystal structure with an average particle size of 19 nm as confirmed from XRD. Also HR-TEM studies reveal the formation of nano-sized silver particles with face centered cubic nano structure. In addition, absorption spectra exhibit Surface Plasmon Resonance (SPR) which suggests the formation of silver nanoparticles. FTIR results show the presence of different characteristic functional groups and their stretching / bending vibrations in turn responsible for the bioreduction of silver ions in Parthenium digested slurry. Further investigations on antimicrobial activity were done by subjecting the synthesized silver nanoparticles on E-coli and Pseudomonas as marker organisms for the group of gram negative bacteria by well plate method on enrichment media. The result obtained shows a clear zone of inhibition confirming the antibacterial activity. Overall, the investigated results confirm the biosynthesized silver nanoparticles are potential candidates for antimicrobial activity applications. Copyright © 2018 Elsevier B.V.

2014-01-01

Highlights: • Optimization of pretreatment methods for Parthenium hysterophorus for bioalcohol production. • Physical, chemical and physicochemical pretreatments methods employed. • Most efficient treatment: autoclaving 121 °C, 15 psi for 30 min in 1% H 2 SO 4 solution. • TFS (total fermentable sugar) yield after pretreatment and enzymatic hydrolysis = 397.7 mg/g raw biomass. • Parthenium hysterophorus is at par with agro- and forest residues as biofuels feedstock. - Abstract: Parthenium hysterophorus world’s seven most devastating and hazardous weeds, and is abundantly available in several parts of the world. This study treats the subject of effective utilization of this waste biomass (which has cellulose content of 45.2 ± 1.81% w/w) for biofuels production. We have presented a comprehensive and comparative assessment of numerous pretreatment strategies for P. hysterophorus, comprising of all major physical, chemical and physicochemical methods. The yardstick of assessment has been amount of fermentable sugars released during the pretreatment and the post-treatment enzymatic hydrolysis of pretreated biomass. Carboxymethylcellulase (1.0 U/mg, 1.7 mg/mL) produced by an isolate Bacillus amyloliquefaciens SS35 and β-glucosidase (Novozyme 188), have been used for enzymatic hydrolysis of pretreated biomass. Among the different methods employed for pretreatment, the most efficient treatment has been revealed to be autoclaving of biomass at 121 °C and 15 psi pressure for 30 min in acidic (1% v/v, H 2 SO 4 ) environment. Total reducing sugar (TRS) yield during this pretreatment, mainly due to hydrolysis of hemicellulosic fraction of biomass, has been 285.3 mg/g of raw biomass. Further enzymatic hydrolysis resulted in reducing sugar yield of 187.4 mg/g of pretreated biomass (9.37 g/L). The total fermentable sugar (TFS) yield from the optimized pretreatment was 397.7 mg/g raw biomass (39.77 g/100 g raw biomass). The effects of different pretreatment methods

Stimulation versus inhibition--bioactivity of parthenin, a phytochemical from Parthenium hysterophorus L.

Science.gov (United States)

Belz, Regina G

2007-09-30

Parthenium hysterophorus L. is an invasive weed that biosynthesizes several phytochemicals. The sesquiterpene lactone parthenin receives most attention regarding allelopathy of the plant or potential herbicidal properties. Since parthenin exhibits dose-dependent phytotoxicity with low dose stimulation, this study investigated the occurrence and temporal features of parthenin hormesis in Sinapis arvensis L. sprayed with parthenin under semi-natural conditions. Dose/response studies showed that the occurrence and the magnitude of hormesis depended on climatic conditions and the parameter measured. Within the tested dose range, stimulatory responses were only observed under less-stressful conditions and were most pronounced for leaf area growth [138 % of control; 13 days after treatment (DAT)]. Temporal assessment of leaf area development showed that doses causing a stimulatory response at the end of the experiment (allelopathy of P. hysterophorus and exploitation of growth stimulatory responses in agriculture.

Full Text Available Tanacetum parthenium (feverfew is an herb that is commercialized worldwide as a therapeutic treatment for migraine. Its pharmacological effect is mainly due to the presence of the sesquiterpene lactone parthenolide as well as of flavonoids. So far, there are no studies on standardization of pre-formulations or phytomedicines containing this herb. The present study aimed at developing a pre-formulation using a standardized spray-dried extract of feverfew and further designing and standardizing enteric coated tablets. In this work, the spray-dried extract of feverfew was evaluated for its parthenolide, santin and total flavonoid content, parthenolide solubility, particle size, tapped density, hygroscopicity, angle of repose and moisture content. Tablets containing the spray-dried extract were tested for their average weight, friability, hardness, and disintegration time. The total flavonoid and parthenolide contents in the spray-dried extract were 1.31 % and 0.76% w/w, respectively. The spray-dried extract presented consistent pharmacotechnical properties and allowed its tableting by direct compression. Tablet properties were in accordance with the proposed specifications. The procedures described herein can be used to prepare and evaluate pre-formulations of feverfew with adequate properties for the development of a high-quality phytomedicine.Tanacetum parthenium (tanaceto é uma planta medicinal comercializada no mundo todo para tratamento de enxaqueca.

Water-distilled essential oils from herbal parts of Tanacetum parthenium from two different localities in Turkey were analyzed by GC and GC/MS. The essential oil of T. parthenium collected from Davutpasa-Istanbul location were characterized with camphor 49%, trans-chrysanthenyl acetate 22.1% and camphene 9.4%. Second plant sample is collected from the remote east end of the country Savşat-Ardahan location. The essential oil from this location was characterized with camphor 60.8% and camphene 6.8%. Unlike the former this sample contains trans-chrysanthenyl acetate in trace amount and cis- chrysanthenyl acetate in very small amount (0.6%) which is not present in the first sample. Antibacterial activity of the oils were evaluated for five Gram (+) and five Gram (-) bacteria by using a broth microdilution assay. The highest activity was observed on Bacillus subtilis, Staphylococcus aureus and methicillin-resistant S.aureus however when compared with positive control oils showed higher MIC values. The oil of Istanbul-sample showed highest activity on B. subtilis (125 microg/mL) and methicillin-resistant S. aureus (125 microg/mL) which is two fold concentration when compared with the positive control chloramphenicol (62.5 microg/mL). The oil of Ardahan sample showed the highest activity on S. aureus (125 microg/mL) which is likewise two fold concentration of the positive control chloramphenicol (62.5 microg/mL). DPPH scavenging activity was 59.3% of the oil from Davutpasa at 15 mg/mL concentration. When compared to positive control alpha-tocopherol (94.6%) Savşat oil (28.2%) showed low and Davutpasa oil showed medium DPPH scavenging activity. All of the oils showed toxicity to Vibrio fischeri in the TLC-bioluminescence assay.

Turning Waste into Value: Nanosized Natural Plant Materials of Solanum incanum L. and Pterocarpus erinaceus Poir with Promising Antimicrobial Activities

Full Text Available Numerous plants are known to exhibit considerable biological activities in the fields of medicine and agriculture, yet access to their active ingredients is often complicated, cumbersome and expensive. As a consequence, many plants harbouring potential drugs or green phyto-protectants go largely unnoticed, especially in poorer countries which, at the same time, are in desperate need of antimicrobial agents. As in the case of plants such as the Jericho tomato, Solanum incanum, and the common African tree Pterocarpus erinaceus, nanosizing of original plant materials may provide an interesting alternative to extensive extraction and isolation procedures. Indeed, it is straightforward to obtain considerable amounts of such common, often weed-like plants, and to mill the dried material to more or less uniform particles of microscopic and nanoscopic size. These particles exhibit activity against Steinernema feltiae or Escherichia coli, which is comparable to the ones seen for processed extracts of the same, respective plants. As S. feltiae is used as a model nematode indicative of possible phyto-protective uses in the agricultural arena, these findings also showcase the potential of nanosizing of crude “waste” plant materials for specific practical applications, especially—but not exclusively—in developing countries lacking a more sophisticated industrial infrastructure.

Electron microscopy of hydrocarbon production in parthenium argentatum (guayule)

Energy Technology Data Exchange (ETDEWEB)

Bauer, Thomas E. [Univ. of California, Berkeley, CA (United States)

1977-11-01

The electron microscope was used to study the biological processes involved in hydrocarbon production. The little desert shrub Guayule (Parthenium argentatum) was selected for study. This shrub can produce hydrocarbons (rubber) in concentrations up to 1/4 of its dry weight. It grows on semi-arid land and has been extensively studied. The potential of Guayule is described in detail. Results of an investigation into the morphology of Guayule at the electron microscope level are given. Experiments, which would allow the biosynthesis of hydrocarbon in Guayule to be followed, were designed. In order to do this, knowledge of the biochemistry of rubber formation was used to select a tracer, mevalonic acid. Mevalonic acid is the precursor of all the terpenoids, a large class of hydrocarbons which includes rubber. It was found that when high enough concentrations of mevalonic acid are administered to seedling Guayule plants, build-ups of metabolized products are found within the chloroplasts of the seedlings. Also, tritium labeled mevalonic acid was used as a precursor, and its metabolic progress was followed by using the technique of electron microscope autoradiography. The results of these experiments also implicated chloroplasts of the Guayule plant in hydrocarbon production. The final task was the development of a system to produce three-dimensional stereo reconstructions of organelles suspected of involvement in hydrocarbon biosynthesis in Guayule. The techniques are designed to reconstruct an object from serial sections of that object. The techniques use stereo imaging both to abstract information for computer processing, and also in the computer produced reconstruction.

Full Text Available Este trabalho foi desenvolvido com o objetivo de avaliar a atividade relativa da catalase em extrato aquoso de losna-branca (Parthenium hysterophorus, bem como comparála à atividade da catalase de outras espécies daninhas. O trabalho constou de três fases, que envolveram a padronização do método, comparação da atividade relativa da catalase de plantas da família Asteraceae e comparação com outras 11 espécies daninhas, sendo estas: Euphorbia heterophylla, Alternanthera tenella, Cenchrus echinatus, Panicum maximum, Amaranthus viridis, Ipomoea hederifolia, Galinsoga parviflora, Bidens pilosa, Sonchus oleraceus, Cyperus rotundus e Commelina benghalensis. Observou-se resposta linear crescente da reação entre extrato aquoso de losna-branca e peróxido de hidrogênio, em razão da concentração do extrato vegetal. Em todas as fases, a atividade relativa da catalase de extrato de losna-branca foi superior à atividade da catalase das demais espécies daninhas. Com os dados obtidos nas três fases, conclui-se que a maior atividade relativa observada para a catalase da losnabranca contribui significativamente para a tolerância dessa espécie ao herbicida paraquat. Essa maior atividade pode ser consequência da maior concentração enzimática nas células ou devido à maior atividade intrínseca da enzima (afinidade enzima-substrato, havendo necessidade de estudos mais precisos para essa conclusão.This work was carried out to evaluate catalase relative activity of ragweed (Parthenium hysterophorus aqueous extract, as well as to compare it with catalase activity of other weed species.

Full Text Available Objective: To assess the larvicidal potential of various extracts prepared from the stem, roots and leaves of Parthenium hysterophorus (P. hysterophorus against 3rd and 4th instars of Aedes aegypti (Ae. aegypti. Methods: The extracts from each part were prepared with four solvents; petroleum ether, hexane, acetone and diethyl ether. Each part was dried, powdered and soaked in different solvents, separately, for five days. The crude extracts thus formed were concentrated using rotary evaporator and stored as stock solution of 1 000 mg/L. Results: All the extracts prepared from the leaves were found ineffective against both the instars causing only 10%-40% mortality. Against 3rd instars, the hexane and petroleum ether extracts prepared from the stem of P. hysterophorus were found effective exhibiting LC50 values of 379.76 and 438.57 mg/L, respectively. Likewise the hexane and petroleum ether extracts from the Parthenium roots resulted in LC50 values of 432.38 and 562.50 mg/L, respectively, against 4th instars of Ae. aegypti revealing their larvicidal potential. It was further found that the hexane extracts, whether from roots or stem, were 13-28% more effective than the petroleum ether extracts. The qualitative phytochemical study of the effective extracts from the stems and roots showed the presence of alkaloids, saponins, terpenoids and flavonoids in different combinations. Conclusions: Our investigations demonstrated the potential of P. hysterophorus roots and stems against Ae. aegypti larvae and their benefits as new types of mosquito larvicides. Variety of types and levels of active constituents in each kind of extract may be responsible for the variability in their potential against Ae. aegypti. Further research is needed to identify these components.

Washed rubber particles isolated from stem homogenates of Parthenium argentatum Gray by ultracentrifugation and gel filtration on columns of LKB Ultrogel AcA34 contain rubber transferase which catalyzes the polymerization of isopentenyl pyrophosphate into rubber polymer. The polymerization reaction requires Mg 2+ isopentenyl pyrophosphate, and an allylic pyrophosphate. The K m values for Mg 2+ , isopentenyl pyrophosphate, and dimethylallyl pyrophosphate were 5.2 x 10 -4 molar, 8.3 x 10 -5 molar, and 9.6 x 10 -5 molar, respectively. The molecular characteristics of the rubber polymer synthesized from [ 14 C]isopentenyl pyrophosphate were examined by gel permeation chromatography. The peak molecular weight of the radioactive polymer increased from 70,000 in 15 minutes to 750,000 in 3 hours. The weight average molecular weight of the polymer synthesized over a 3 hour period was 1.17 x 10 6 compared to 1.49 x 10 6 for the natural rubber polymer extracted from the rubber particles. Over 90% of the in vitro formation of the rubber polymer was de novo from dimethylallyl pyrophosphate and isopentenyl pyrophosphate. Treatment of the washed rubber particles with 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate solubilized the rubber transferase. The solubilized enzyme(s) catalyzed the polymerization of isopentenyl pyrophosphate into rubber polymer with a peak molecular weight of 1 x 10 5 after 3 hours of incubation with Mg 2+ and dimethylallyl pyrophosphate. The data support the conclusion that the soluble preparation of rubber transferase is capable of catalyzing the formation of a high molecular weight rubber polymer from an allylic pyrophosphate initiator and isopentenyl pyrophosphate monomer

The Genus Cerion (Gastropoda: Cerionidae in the Florida Keys.

Yesha Shrestha

Full Text Available The systematic relationships and phylogeography of Cerion incanum, the only species of Cerion native to the Florida Keys, are reviewed based on partial sequences of the mitochondrial COI and 16S genes derived from 18 populations spanning the range of this species and including the type localities of all four described subspecies. Our samples included specimens of Cerion casablancae, a species introduced to Indian Key in 1912, and a population of C. incanum x C. casablancae hybrids descended from a population of C. casablancae introduced onto Bahia Honda Key in the same year. Molecular data did not support the partition of C. incanum into subspecies, nor could populations be apportioned reliably into subspecies based on morphological features used to define the subspecies. Phylogenetic analyses affirmed the derived relationship of C. incanum relative to other cerionids, and indicated a Bahamian origin for the Cerion fauna of southern Florida. Relationships among the populations throughout the Keys indicate that the northernmost populations, closest to the Tomeu paleoislands that had been inhabited by Cerion petuchi during the Calabrian Pleistocene, are the oldest. The range of Cerion incanum expanded as the archipelago that is the Florida Keys was formed since the lower Tarantian Pleistocene by extension from the northeast to the southwest, with new islands populated as they were formed. The faunas of the High Coral Keys in the northeast and the Oölite Keys in the southwest, both with large islands that host multiple discontinuous populations of Cerion, are each composed of well supported clades that are characterized by distinctive haplotypes. In contrast, the fauna of the intervening Low Coral Keys consist of a heterogeneous series of populations, some with haplotypes derived from the High Coral Keys, others from the Oölite Keys.

Pollution caused by vehicular exhaust emissions detrimentally affect plants and other living beings. This investigation was carried out to evaluate the effects of vehicular exhaust pollutants on Parthenium hysterophorus at various sites along two major roads [Pindi Bhattian to Lillah (M-2) and Faisalabad to Sargodha (FSR)]in the Punjab, Pakistan. Control samples of P. hysterophorus were also collected from 100m away from the roads. Chlorophyll contents, photosynthetic rate, transpiration rate, stomatal conductance, substomatal CO/sub 2/ concentration, water use efficiency, total free amino acids and total antioxidant activity of P. hysterophorus were measured. The results depicted significant reductions in chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents of P. hysterophorus. Likewise, reduction in stomatal conductance was also recorded which resulted in lowered photosynthetic and transpiration rates. The overall reduction in photosynthetic rate of P. hysterophorus was 30.92% and 35.38% along M-2 and FSR roads, respectively. The limited photosynthesis resulted in increased levels of sub stomatal /sub 2/ concentration and water use efficiency. The elevated levels of free amino acids and total antioxidant activity were noted and could be attributed to activation of plant's defense system to cope with the deleterious effects of vehicular air pollutants. The significant correlations between various attributes of P. hysterophorus with traffic density signifies the stress caused by vehicular emissions. (author)

Full Text Available La berenjena (Solanum melongena L. es un cultivo con una estrecha base genética. Esto puede deberse a que la domesticación de la berenjena se realizó a partir de un acervo genético limitado, lo cual pudo originar un efecto fundador, que contribuiría a que las variedades de berenjena cultivadas presenten una baja diversidad genética. En la actualidad se está desarrollando una colección de líneas de introgresión de S. incanum en el fondo genético de S. melongena (MIILs, que junto con estudios de selección asistida por marcadores permitirán dilucidar el control genético e identificar QTLs de caracteres importantes como la forma, tamaño y color del fruto, contenido en antocianinas y polifenoles de la pulpa, la espinosidad, resistencias y tolerancias a estreses bióticos y abióticos. Los objetivos de la presente investigación fueron realizar la caracterización tanto fenotípica como fenómica y la evaluación del contenido en ácido clorogénico de los frutos de la segunda generación de autofecundación para la construcción de las MIILs. La caracterización fenotípica y fenómica realizada mostró una considerable variabilidad en los caracteres evaluados entre las MIILs. La caracterización detallada de la forma del fruto utilizando el programa Tomato Analyzer proporcionó datos cuantitativos sobre muchos caracteres que no se obtienen utilizando descriptores morfológicos medidos manualmente, dichos datos permitieron detectar diferencias entre las MIILs. El estudio del control genético en cuanto a la acumulación de polifenoles, en particular del ácido clorogénico mostró que las MIILs presentaron contenidos muy diferentes entre ellas y algunas superaron claramente los contenidos de los parentales.

Competitive Exclusion of Parthenium hysterophorus by Other Invasive Species - A Case Study from Andhra Pradesh, India

2010-06-01

Full Text Available The abundance, dominance and growth performance of Parthenium hysterophorus in relation to its field associates in extensively large areas was investigated. The preliminary analysis of the data revealed that P. hysterophorus is a weak or poor competitor and hence it fails to grow in the company of any aggressive species. Senna uniflora and a few other plants were identified for the control of this pernicious weed. The ability of other species to control P. hysterophorus was attributed to allelopathy. In order to understand how Hyptis suaveolens and Senna uniflora are capable of arresting the growth of P. hysterophorus, pot culture experiments in de Wit replacement series, field experiments in experimental plots and experimental manipulation of the competitive species under natural conditions during different seasons were carried out for two years in 2004 and 2005. The results clearly revealed that both H. suaveolens and S. uniflora were highly effective in the management of P. hysterophorus. The results further showed that the physical dominance and the ability of the competitive species to deprive P. hysterophorus of light are mainly responsible for the decline of P. hysterophorus. Allelopathy doesn't seem to play any effective role under natural conditions.

Soil degradation of parthenin-does it contradict the role of allelopathy in the invasive weed Parthenium hysterophorus L.?

Belz, Regina G; van der Laan, Michael; Reinhardt, Carl F; Hurle, Karl

2009-09-01

The invasive success of Parthenium hysterophorus L. is thought to be partially attributable to allelopathy mediated by the plant metabolite parthenin. To assess the ecological significance of parthenin release from plant material, its persistence and phytotoxicity in soil was studied. Results show parthenin is rapidly degraded with an average DT (50) of 59 h under standard experimental conditions. Degradation was delayed in sterilized soils, at lower soil moisture, and higher parthenin concentrations. Higher temperatures, higher CEC(pot)/clay content of soils, soil preconditioning with parthenin, and P. hysterophorus infestation accelerated degradation. Physico-chemical and biological processes are, therefore, expected to govern the fate of parthenin in soil. Parthenin exhibited low soil phytotoxicity and did not accumulate over time. Along with the indicated reduction in bioavailability and development of hormetic effects, results suggest that for parthenin to have detrimental allelopathic effects, it requires high P. hysterophorus densities that result in high soil levels of parthenin and soil conditions that favor the persistence of parthenin. In light of this, the ecological significance of parthenin is discussed.

This paper presents investigations into mechanism of ultrasound assisted bioethanol synthesis using Parthenium hysterophorus biomass through simultaneous saccharification and fermentation (SSF) mode. Approach of coupling experimental results to mathematical model for SSF using Genetic Algorithm based optimization has been adopted. Comparison of model parameters for experiments with mechanical shaking and sonication (10% duty cycle) give an interesting mechanistic account of influence of ultrasound on SSF system. A 4-fold rise in ethanol and cell mass productivity is seen with ultrasound. The analysis reveals following facets of influence of ultrasound on SSF: increase in Monod constant for glucose for cell growth, maximal specific growth rate and inhibition constant of cell growth by glucose and reduction in specific cell death rate. Values of inhibition constant of cell growth by ethanol (K3E), and constants for growth associated (a) and non-growth associated (b) ethanol production remained unaltered with sonication. Beneficial effects of ultrasound are attributed to enhanced cellulose hydrolysis, enhanced trans-membrane transport of substrate and products as well as dilution of the toxic substances due to micro-convection induced by ultrasound. Intrinsic physiological functioning of cells remained unaffected by ultrasound as indicated by unaltered values of K3E, a and b. Copyright © 2015 Elsevier B.V. All rights reserved.

A series of brief notes accompanied this presentation which was divided into seven sections entitled: (1) capital markets update, (2) Mexican financial market update, (3) financing options in the energy industry, (4) the Venezuelan experience at La Apertura, (5) private and strategic equity alternatives, (6) Pricewaterhouse Coopers Securities, and (7) Mexico energy 2005 prediction. The paper focused on how the financial crisis and merger activity in Latin America will impact electricity reform in Mexico. It was noted that under Mexico`s Policy Proposal for Electricity Reform of the Mexican Electricity Industry, the financial community will seek to back companies in power generation, transportation and distribution. The difficulty of financing government businesses undergoing privatization was also discussed with particular emphasis on the challenge of accepting political and regulatory risks. The Latin private equity market and Canadian investment in Mexico was also reviewed. Since NAFTA (North American Free Trade Agreement) went into affect in 1994, Canadian investment in Mexico has more than tripled. Canadian companies have invested more than C$1.7 billion in Mexico since NAFTA. Pricewaterhouse Coopers Securities is a global investment bank which sees large opportunities in the Mexican energy market. They predict that in five years, Mexico will experience a gradual liberalization of the oil and gas sector, and a full liberalization of the gas pipeline and distribution business and the power generation, transmission and distribution business. 3 figs.

Most cases having air-borne contact dermatitis (ABCD) in India are considered to be caused by Parthenium hysterophorus. In some cases however, other plants have also been noticed to give positive patch test reactions. We are reporting two cases presenting as ABCD who showed positive patch tests with Xanthium strumarium while the patch tests with Parthenium hysterophorus were negative. It is therefore necessary to realise that every case of ABCD is not caused by Parthenium, and patch testing with Parthenium alone can lead to serious mistakes.

We describe the spatial variation in the structure and composition of the communities of insects visiting the inflorescences of Flaveria ramosissima Klatt, Florestina pedata (Cav.) Cass., and Parthenium bipinnatifidum (Ort.) Rollins (Asteraceae) in a xeric environment in Central Mexico. Inflorescences of the three Asteraceae were visited by a total of 96 species of Hymenoptera, Diptera, Lepidoptera, Coleoptera, and Hemiptera. Total species richness of floral visitors to the three Asteraceae and total abundance of insects of Fl. pedata and P. bipinnatifidum did not differ between low and high vegetation cover sites. Total abundance of insects visiting the inflorescences of F. ramosissima and abundance of Hymenoptera in all three Asteraceae were higher at the low vegetation coverage (LVC) site than at the high vegetation coverage (HVC) one. Diversity of insects of Fl. pedata and P. bipinnatifidum was higher at the HVC site. However, in F. ramosissima diversity was higher at the LVC site. The communities of insects of each Asteraceae were dissimilar between sites. These differences can be attributed to variation in the abundance of Lepidophora (Diptera: Bombyliidae), Miridae (Hemiptera), Melyridae (Coleoptera), Tiphiidae (Hymenoptera), Myrmecocystus mexicanus Wesmael, and Dorymyrmex grandulus (Forel) (Hymenoptera: Formicidae). The first three insect groups were sensitive to LVC, high temperature, and low humidity, whereas the last three tolerated those same environmental conditions. Changes in temperature, humidity, and resources associated with vegetation coverage seem to differentially affect each species of floral visitors of the three Asteraceae species studied. © The Authors 2016.

The use of congress grass (Parthenium sp.) and water hyacinth (Eichhornia crassipes) as low cost raw materials for xylanase production from mutant Penicillium oxalicum SAU E -3.510 in submerged fermentation was investigated. For development of mutant from wild type P. oxalicum SA-8 ITCC 6024, a strategy of mixed mutagenesis was followed using UV-irradiation and ethidium bromide, which had resulted into 1.87 fold increases in the activity of the enzyme. For enzyme production, the fungus was cultivated in mineral medium containing congress grass as carbon source. Considerably higher levels of production (475.2 ± 6.0 IU ml -1 ) were achieved in media containing congress grass, although it was slightly less than that was obtained (488.5 ± 6.5 IU ml -1 ) in presence of commercial oat spelt xylan. This fact confirms the feasibility of using this low cost non-food resource as an alternative carbon source to save costs of the enzyme production process. Maximum xylanase activity was reported at 55 deg. C with its stability at 80 deg. C for 2 h. The highest activity of xylanase at pH 9.0 and its stability at similar pH for 24 h denote the alkalitolerant nature of enzyme

This presentation highlights the results of a recently completed study that examines the Texas- Mexico multimodal transport system already in place, current plans for improvements or expansion, and opportunities and constraints faced by each transport mode -- motor carriage, rail, maritime, and air. Particular emphasis is given to findings regarding transportation developments in Mexico. The study concludes that in Mexico, all modes are working at establishing new services and strategic alliances, intermodal arrangements are on the rise, and private-sector participation in infrastructure improvements is growing daily at Mexican seaports and airports as well as within that nation's highway and rail systems. This presentation looks at developments that concern privatization, deregulation, infrastructure improvements, financing arrangements, and new services in Mexico.

The use of congress grass (Parthenium sp.) and water hyacinth (Eichhornia crassipes) as low cost raw materials for xylanase production from mutant Penicillium oxalicum SAU{sub E}-3.510 in submerged fermentation was investigated. For development of mutant from wild type P. oxalicum SA-8 ITCC 6024, a strategy of mixed mutagenesis was followed using UV-irradiation and ethidium bromide, which had resulted into 1.87 fold increases in the activity of the enzyme. For enzyme production, the fungus was cultivated in mineral medium containing congress grass as carbon source. Considerably higher levels of production (475.2 {+-} 6.0 IU ml{sup -1}) were achieved in media containing congress grass, although it was slightly less than that was obtained (488.5 {+-} 6.5 IU ml{sup -1}) in presence of commercial oat spelt xylan. This fact confirms the feasibility of using this low cost non-food resource as an alternative carbon source to save costs of the enzyme production process. Maximum xylanase activity was reported at 55 C with its stability at 80 C for 2 h. The highest activity of xylanase at pH 9.0 and its stability at similar pH for 24 h denote the alkalitolerant nature of enzyme. (author)

Occurrence of plant sensitivity among patients of photodermatoses: A control-matched study of 156 cases from New Delhi

2009-01-01

Full Text Available Background: Photodermatitis is an abnormal response to ultraviolet radiation (UVR. The photoallergic contact dermatitis caused by plant allergens is a serious cause of morbidity in India. Airborne contact dermatitis is the classical presentation of plant-induced dermatosis, which may become difficult to differentiate from chronic actinic dermatitis in chronic cases. The rapid growth of parthenium weed in India and its ill effects on the population make it important to detect all cases of parthenium sensitivity, which in some cases might simulate photodermatitis. Aims: This study aims to detect the occurrence of plant sensitivity and photosensitivity in idiopathic-acquired photodermatoses, airborne contact dermatitis and general population taken as controls. Methods: One hundred and fifty six consecutive patients suffering from polymorphic light eruption (PMLE, chronic actinic dermatitis (CAD and airborne contact dermatitis (ABCD were enrolled in the study over a period of three years (June 2004 to May 2007. An equal number of age and sex matched healthy subjects were enrolled in the study as controls. All the patients were subjected to detailed history taking, clinical examination and histopathological examination for diagnosis. Patch and photopatch testing were perfomed in all the patients and healthy controls for detection of allergic and photoallergic reactions to parthenium, xanthium and chrysanthemum plant antigens and control antigens. Results: Out of 156 patients enrolled in the study, 78 (50% had CAD, 67 (42.9% had PMLE and 11 (7.05% had ABCD. The occurrence of parthenium/xanthium allergy and photoallergy, either to parthenium or both was most commonly found in ABCD (72.7%, followed by CAD (32%. In PMLE 4.5% cases showed photoallergy. Only 1.9% in the control group showed sensitivity to parthenium and xanthium. Conclusion: This study indicates that parthenium (and possibly xanthium may act as important environmental factors in the

Opportunity for America: Mexico`s coal future

Energy Technology Data Exchange (ETDEWEB)

Loose, V.W.

1993-09-01

This study examines the history, current status and future prospects for increased coal use in Mexico. Environmental implications of the power-generation capacity expansion plans are examined in general terms. Mexican environmental law and regulations are briefly reviewed along with the new sense of urgency in the cleanup of existing environmental problems and avoidance of new problems as clearly mandated in recent Mexican government policy initiatives. It is expected that new capital facilities will need to incorporate the latest in process and technology to comply with existing environmental regulation. Technology developments which address these issues are identified. What opportunities have new initiatives caused by the recent diversification of Mexico`s energy economy offered US firms? This report looks at the potential future use of coal in the Mexican energy economy, examining this issue with an eye toward identifying markets that might be available to US coal producers and the best way to approach them. Market opportunities are identified by examining new developments in the Mexican economy generally and the energy economy particularly. These developments are examined in light of the current situation and the history which brought Mexico to its present status.

This paper reports that while Mexico's petrochemical industry has grown rapidly, it now faces shortages both in investment funds and in supplies of basic petrochemicals due to a financial crisis in the 1980s. Mexico has undertaken a series of policy reforms aimed at encouraging foreign and private investment, but these efforts have generally failed to entice U.S. investment in Mexico. U.S. petrochemical companies have cited unfavorable market conditions, insufficient basic petrochemical capacity in Mexico, concern about the reversibility of Mexican reforms, inadequate Mexican protection of intellectual property rights, and lack of investment protection for U.S. businesses as impediments to investment in Mexico. Cooperation between the two nations in overcoming these obstacles could help U.S. petrochemical companies maintain their positions in a competitive global market, while at the same time provide Mexico with much needed capital investment and technological expertise

This article reviews the literature on migration and HIV/AIDS in Mexico and Central America, including Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Most migrants travel to the US through Mexico. US-Mexico trade agreements created opportunities for increased risk of HIV transmission. The research literature focuses on Mexico. Most countries, with the exception of Belize and Costa Rica, are sending countries. Human rights of migrants are violated in transit and at destination. Migration policies determine migration processes. The Mexican-born population in the US is about 3% of US population and 8% of Mexico's population. About 22% arrived during 1992-97, and about 500,000 are naturalized US citizens. An additional 11 million have a Mexican ethnic background. Mexican migrants are usually economically active men who had jobs before leaving and were urban people who settled in California, Texas, Illinois, and Arizona. Most Mexican migrants enter illegally. Many return to Mexico. The main paths of HIV transmission are homosexual, heterosexual, and IV-drug-injecting persons. Latino migrants frequently use prostitutes, adopt new sexual practices including anal penetration among men, greater diversity of sexual partners, and use of injectable drugs.

An approach to the development of a national strategy for controlling invasive alien plant species: The case of Parthenium hysterophorus in South Africa

Directory of Open Access Journals (Sweden)

Colette Terblanche

2016-06-01

Full Text Available Invasive alien species require co-ordinated strategic management if negative impacts are to be effectively avoided. Here we describe a strategy for the management of Parthenium hysterophorus L. (Asteraceae in South Africa. P. hysterophorus is an annual herb native to tropical America, which has become invasive in over 30 countries. The strategy sets goals for (1 the prevention of spread to new areas; (2 local eradication of isolated populations; (3 containment in areas where eradication is not possible; and (4 actions to protect assets where containment is no longer an option. We developed both a national strategy to set policy and to monitor progress towards goals at a national level and an implementation plan to set goals and timeframes for their achievement at local levels. It is not clear, at this stage, whether or not the goals of the strategy are achievable because implementation will face many challenges arising from ecological features of the target plant, social and cultural practices that will influence management, inadequate levels of funding and multiple political considerations. Our strategy proposes regular assessment using high-level indicators, a practice that is widely recognised as essential but seldom implemented at a national scale. Because the outcomes are uncertain, it is vital that regular monitoring of outcomes should be instituted from the start, so that both appropriate adjustments can be made to the strategy and lessons for the implementation of similar strategies elsewhere can be derived.

1995-01-01

The New Mexico Bureau of Mines and Mineral Resources (NMBMMR) in cooperation with the Radiation Licensing and Registration Section of the New Mexico Environment Department (NMED) and the US Environmental Protection Agency (EPA) have been evaluating geologic and soil conditions that may contribute to elevated levels of indoor radon throughout New Mexico. Various data have been integrated and interpreted in order to determine areas of high radon availability. The purpose of this paper is to summarize some of these data for New Mexico and to discuss geologic controls on the distribution of radon. Areas in New Mexico have been identified from these data as having a high radon availability. It is not the intent of this report to alarm the public, but to provide data on the distribution of radon throughout New Mexico

Mexico's nuclear paradox

International Nuclear Information System (INIS)

Redclift, M.

1989-01-01

Opposition to Mexico's nuclear reactors at Laguna Verde has grown during the last two years. The nuclear programme is blamed for being expensive and wasteful, and the decision to rely on the USA contradicts Mexico's espoused policy of greater independence from the USA. The way in which petroleum revenues were used to precipitate the nuclear option is compared with the lack of urgency given to renewable energy and greater energy efficiency. From a social and environmental perspective, as well as an economic one, Mexico's nuclear programme is judged expensive and irrelevant. (author)

Mexico Wind Resource Assessment Project

Energy Technology Data Exchange (ETDEWEB)

Schwartz, M.N.; Elliott, D.L.

1995-05-01

A preliminary wind energy resource assessment of Mexico that produced wind resource maps for both utility-scale and rural applications was undertaken as part of the Mexico-U.S. Renewable Energy Cooperation Program. This activity has provided valuable information needed to facilitate the commercialization of small wind turbines and windfarms in Mexico and to lay the groundwork for subsequent wind resource activities. A surface meteorological data set of hourly data in digital form was utilized to prepare a more detailed and accurate wind resource assessment of Mexico than otherwise would have been possible. Software was developed to perform the first ever detailed analysis of the wind characteristics data for over 150 stations in Mexico. The hourly data set was augmented with information from weather balloons (upper-air data), ship wind data from coastal areas, and summarized wind data from sources in Mexico. The various data were carefully evaluated for their usefulness in preparing the wind resource assessment. The preliminary assessment has identified many areas of good-to-excellent wind resource potential and shows that the wind resource in Mexico is considerably greater than shown in previous surveys.

The background notes on Mexico provide text and recent statistical information on the geography, population, government, economy, and foreign relations, specifically the North American Free Trade Agreement with US. The 1992 population is estimated at 89 million of which 60% are mestizo (Indian-Spanish), 30% are American Indian, 9% are Caucasian, and 1% are other. 90% are Roman Catholic. There are 8 years of compulsory education. Infant mortality is 30/1000 live births. Life expectancy for males is 68 years and 76 years for females. The labor force is comprised of 30% in services, 24% in agriculture and fishing, 19% in manufacturing, 13% in commerce, 7% in construction, 4% in transportation and communication, and .4% in mining. There are 31 states and a federal district. Gross domestic product (GDP) per capita was $3200 in 1991. Military expenditures were .5% of GDP in 1991. The average inflation rate is 19%. Mexico City with 20 million is the largest urban center in the world. In recent years, the economy has been restructured with market oriented reforms; the result has been a growth of GDP of 3.6% in 1991 from 2% in 1987. Dependence on oil exports has decreased. There has been privatization and deregulation of state-owned companies. Subsidies to inefficient companies have been stopped. Tariff rates were reduced. The financial debt has been reduced and turned into a surplus of .8% in 1992. Mexico's foreign debt has been reduced from its high in 1987 of $107 billion. Agricultural reforms have been ongoing for 50 years. Land was redistributed, but standards of living and productivity have improved only slightly. Rural land tenure regulations have been changed, and other economic reforms are expected. Mexico engages in ad hoc international groups and is selective about membership in international organizations.

The Comprehensive Nuclear Test-Ban-Treaty (CTBT) is a treaty that prohibits all the nuclear explosions by anybody and in any place, either on the terrestrial surface, in the atmosphere, under the sea or underground. From the adoption of this Treaty by the United Nations, Mexico has had interest for its entrance in vigor, as integral part to assure the international peace. For this reason, our country signed the Treaty since it was open in September 24, 1996 and three years later ratified it, due to Mexico is part of the group of necessary countries for their entrance in vigor. During 13 years, the country has been committed and helped to the installation of monitoring stations, actions that allow the strengthening of the International System of Surveillance. The purpose of this work is to divulge the Treaty,its technologies and benefits; and also to diffuse the works realized by Mexico regarding the radionuclides monitoring station and noble gases both certified ones for the CTBT. Besides the radionuclides technology, Mexico has taken charge of the installation and operation of the seismic stations and hydro-acoustics that have been certified too. The radionuclides station Rn-44 located in Guerrero Negro, BCS has two technologies, an automated sampler of suspended particles in air brand Cinderella/ARAME and a noble gases system Sauna used for the particles detection of radioactive material gamma emitting and Xenon radioisotopes product of nuclear assays. Both technologies are transmitting data in real time to the International Center of Data. These technologies are shown in this work. (Author)

Geothermal energy from deep sedimentary basins: The Valley of Mexico (Central Mexico)

Science.gov (United States)

Lenhardt, Nils; Götz, Annette E.

2015-04-01

The geothermal potential of the Valley of Mexico has not been addressed in the past, although volcaniclastic settings in other parts of the world contain promising target reservoir formations. A first assessment of the geothermal potential of the Valley of Mexico is based on thermophysical data gained from outcrop analogues, covering all lithofacies types, and evaluation of groundwater temperature and heat flow values from literature. Furthermore, the volumetric approach of Muffler and Cataldi (1978) leads to a first estimation of ca. 4000 TWh (14.4 EJ) of power generation from Neogene volcanic rocks within the Valley of Mexico. Comparison with data from other sedimentary basins where deep geothermal reservoirs are identified shows the high potential of the Valley of Mexico for future geothermal reservoir utilization. The mainly low permeable lithotypes may be operated as stimulated systems, depending on the fracture porosity in the deeper subsurface. In some areas also auto-convective thermal water circulation might be expected and direct heat use without artificial stimulation becomes reasonable. Thermophysical properties of tuffs and siliciclastic rocks qualify them as promising target horizons (Lenhardt and Götz, 2015). The here presented data serve to identify exploration areas and are valuable attributes for reservoir modelling, contributing to (1) a reliable reservoir prognosis, (2) the decision of potential reservoir stimulation, and (3) the planning of long-term efficient reservoir utilization.

Uranium resources in New Mexico

International Nuclear Information System (INIS)

McLemore, V.T.; Chenoweth, W.L.

1989-01-01

For nearly three decades (1951-1980), the Grants uranium district in northwestern New Mexico produced more uranium than any other district in the world. The most important host rocks containing economic uranium deposits in New Mexico are sandstones within the Jurassic Morrison Formation. Approximately 334,506,000 lb of U 3 O 8 were produced from this unit from 1948 through 1987, accounting for 38% of the total uranium production from the US. All of the economic reserves and most of the resources in New Mexico occur in the Morrison Formation. Uranium deposits also occur in sandstones of Paleozoic, Triassic, Cretaceous, Tertiary, and Quaternary formations; however, only 468,680 lb of U 3 O 8 or 0.14% of the total production from New Mexico have been produced from these deposits. Some of these deposits may have a high resource potential. In contrast, almost 6.7 million lb of U 3 O 8 have been produced from uranium deposits in the Todilto Limestone of the Wanakah Formation (Jurassic), but potential for finding additional economic uranium deposits in the near future is low. Other uranium deposits in New Mexico include those in other sedimentary rocks, vein-type uranium deposits, and disseminated magmatic, pegmatitic, and contact metasomatic uranium deposits in igneous and metamorphic rocks. Production from these deposits have been insignificant (less than 0.08% of the total production from New Mexico), but there could be potential for medium to high-grade, medium-sized uranium deposits in some areas. Total uranium production from New Mexico from 1948 to 1987 amounts to approximately 341,808,000 lb of U 3 O 8 . New Mexico has significant uranium reserves and resources. Future development of these deposits will depend upon an increase in price for uranium and lowering of production costs, perhaps by in-situ leaching techniques

Subsidence Induced Faulting Hazard risk maps in Mexico City and Morelia, central Mexico

Subsidence and surface faulting have affected urban areas in Central Mexico for decades and the process has intensified as a consequence of urban sprawl and economic growth. This process causes substantial damages to the urban infrastructure and housing structures and in several cities it is becoming a major factor to be considered when planning urban development, land use zoning and hazard mitigation strategies in the next decades. Subsidence is usually associated with aggressive groundwater extraction rates and a general decrease of aquifer static level that promotes soil consolidation, deformation and ultimately, surface faulting. However, local stratigraphic and structural conditions also play an important role in the development and extension of faults. Despite its potential for damaging housing, and other urban infrastructure, the economic impact of this phenomena is poorly known, in part because detailed, city-wide subsidence induced faulting risk maps have not been published before. Nevertheless, modern remote sensing techniques are most suitable for this task. We present the results of a risk analysis for subsidence induced surface faulting in two cities in central Mexico: Morelia and Mexico City. Our analysis in Mexico City and Morelia is based on a risk matrix using the horizontal subsidence gradient from a Persistent Scatterer InSAR (Morelia) and SqueeSAR (Mexico City) analysis and 2010 census population distribution data from Mexico's National Institute of Statistics and Geography. Defining subsidence induced surface faulting vulnerability within these urbanized areas is best determined using both magnitude and horizontal subsidence gradient. Our Morelia analysis (597,000 inhabitants with localized subsidence rates up to 80 mm/yr) shows that 7% of the urbanized area is under a high to very high risk level, and 14% of its population (11.7% and 2.3% respectively) lives within these areas. In the case of the Mexico City (15'490,000 inhabitants for the

Yes… Mexico is a racist country

DEFF Research Database (Denmark)

Carrales, Juan Carlos Finck

2017-01-01

According to recent official statistics, in Mexico there is a relation between people’s privileges and their skin color: The lighter, the more privilege. However, social exclusion by racist practices in Mexico has been common practically since its Spanish conquest between 1519 and 1521, in which...... privileges where absorbed and monopolized by European settlers in Mexico (Spanish people: peninsulares) and their descendants (creole: criollos). As a consequence, currently in Mexico, the color of skin affects people’s economic and political privileges and powers in individual and social levels related...

History of nonnative Monk Parakeets in Mexico.

Science.gov (United States)

Hobson, Elizabeth A; Smith-Vidaurre, Grace; Salinas-Melgoza, Alejandro

2017-01-01

Nonnative Monk Parakeets have been reported in increasing numbers across many cities in Mexico, and were formally classified as an invasive species in Mexico in late 2016. However, there has not been a large-scale attempt to determine how international pet trade and national and international governmental regulations have played a part in colonization, and when the species appeared in different areas. We describe the changes in regulations that led the international pet trade market to shift to Mexico, then used international trade data to determine how many parakeets were commercially imported each year and where those individuals originated. We also quantified the recent increases in Monk Parakeet (Myiopsitta monachus) sightings in Mexico in both the scientific literature and in citizen science reports. We describe the timeline of increased reports to understand the history of nonnative Monk Parakeets in Mexico. As in other areas where the species has colonized, the main mode of transport is through the international pet trade. Over half a million Monk Parakeets were commercially imported to Mexico during 2000-2015, with the majority of importation (90%) occurring in 2008-2014, and almost all (98%) were imported from Uruguay. The earliest record of a free-flying Monk Parakeet was observed during 1994-1995 in Mexico City, but sightings of the parakeets did not become geographically widespread in either the scientific literature or citizen science databases until 2012-2015. By 2015, parakeets had been reported in 97 cities in Mexico. Mexico City has consistently seen steep increases in reporting since this species was first reported in Mexico. Here we find that both national and international legal regulations and health concerns drove a rise and fall in Monk Parakeet pet trade importations, shortly followed by widespread sightings of feral parakeets across Mexico. Further monitoring of introduced Monk Parakeet populations in Mexico is needed to understand the

Vargas Bustamante, Arturo; Laugesen, Miriam; Caban, Mabel; Rosenau, Pauline

2012-01-01

While U.S. health care reform will most likely reduce the overall number of uninsured Mexican-Americans, it does not address challenges related to health care coverage for undocumented Mexican immigrants, who will remain uninsured under the measures of the reform; documented low-income Mexican immigrants who have not met the five-year waiting period required for Medicaid benefits; or the growing number of retired U.S. citizens living in Mexico, who lack easy access to Medicare-supported services. This article reviews two promising binational initiatives that could help address these challenges-Salud Migrante and Medicare in Mexico; discusses their prospective applications within the context of U.S. health care reform; and identifies potential challenges to their implementation (legal, political, and regulatory), as well as the possible benefits, including coverage of uninsured Mexican immigrants, and their integration into the U.S. health care system (through Salud Migrante), and access to lower-cost Medicare-supported health care for U.S. retirees in Mexico (Medicare in Mexico).

A North Sea approach for Mexico?; El marco Mar del Norte para Mexico?

The probable existence of oil and gas deposits in the border territory between Mexico and the United States has waked up an enormous restlessness given the lack of agreements and stipulations on the handling of such deposits; cases like this one have occurred in other parts of the globe and it is indeed the intention of this article to show how the agreement decided on the North Sea can be applied in the case of Mexico. The bilateral characteristics of this agreement conformed by incentives and openings to the market, require the cooperation of different offices and governmental sectors from the federal government to make a series of possible stipulations that regulate the treaty and allow different oil companies a substantial interaction that profits the owners on both sides of the border. In Mexico the responsibility to put in action projects of this type corresponds to the legislative power in complicity with the secretariats of Foreign Affairs and Work. The present action models and the monopoly of Petroleos Mexicanos (PEMEX) in Mexico have only managed to suspend the development of the country in this sector and to maintain the oil industry development in a mediocre and deteriorated level. The benefits of such an adjustment would extend beyond obtaining a bilateral development for the involved countries; nevertheless we remember that the government of the United States is not to the compass of the governments pro-unification of borders. In order to begin the unification of the border regions, Mexico must document the location of border wells, nevertheless even though any agreement could be reached, years would have to pass before PEMEX develops the appropriate technology to operate its part of the deposits.

Mexico is a country at the crossroads. It has huge potentials in energy, in natural resources and in human resources. It is currently experiencing one of the most serious crises in its history - economic, ecological, political - and it is making efforts to overcome the problems behind these crises, which may affect us all because of Mexico's importance as energy producer and energy consumer. Mexico is one of the developing countries which has participated actively in finding solutions to the worlds environmental problems not least the problem of climatic changes as a result of increasing energy consumption. Mexico is seeing the consequences at local and national level, and is taking steps to change course. At the same time, it has also expressed interest in participating in international initiatives and cooperation to solve these problem. But Mexico finds itself in a situation not unlike that of many East European countries after the fall of the communist regimes. The old system is tumbling, the will to change is present, but there is a lack of resources. 123 refs., 45 tabs

Mesozoic Continental Sediment-dispersal Systems of Mexico Linked to Development of the Gulf of Mexico

Major sediment dispersal systems on western Pangea evolved in concert with thermal uplift, rift and drift phases of the Gulf of Mexico Basin, and were influenced by development of a continental arc on Pangea's western margin. Existing literature and preliminary data from fieldwork, sandstone petrology and detrital zircon analysis reveal how major drainages in Mexico changed from Late Triassic through Late Jurassic time and offer predictions for the ultimate destinations of sand-rich detritus along the Gulf and paleo-Pacific margins. Late Triassic rivers drained away from and across the present site of the Gulf of Mexico, which was then the location of a major thermal dome, the Texas uplift of recent literature. These high-discharge rivers with relatively mature sediment composition fed a large-volume submarine fan system on the paleo-Pacific continental margin of Mexico. Predictably, detrital zircon age populations are diverse and record sources as far away as the Amazonian craton. This enormous fluvial system was cut off abruptly near the Triassic-Jurassic boundary by extensive reorganization of continental drainages. Early and Middle Jurassic drainage systems had local headwaters and deposited sediment in extensional basins associated with arc magmatism. Redbeds accumulated across northern and eastern Mexico and Chiapas in long, narrow basins whose locations and dimensions are recorded primarily by inverted antiformal massifs. The Jurassic continental successions overlie Upper Triassic strata and local subvolcanic plutons; they contain interbedded volcanic rocks and thus have been interpreted as part of the Nazas continental-margin arc. The detritus of these fluvial systems is volcanic-lithic; syndepositional grain ages are common in the detrital zircon populations, which are mixed with Oaxaquia-derived Permo-Triassic and Grenville age populations. By this time, interior Pangea no longer supplied sediment to the paleo-Pacific margin, possibly because the

Chromium toxicity tolerance of Solanum nigrum L. and Parthenium hysterophorus L. plants with reference to ion pattern, antioxidation activity and root exudation.

Chromium (Cr), being a highly toxic metal, adversely affects the mineral uptake and metabolic processes in plants when present in excess. The current study was aimed at investigating the Cr accumulation in various plant tissues and its relation to the antioxidation activity and root exudation. Plants were grown in soil spiked with different concentrations of Cr for three weeks in pots and analysed for different growth, antioxidants and ion attributes. Furthermore, plants treated with different concentrations of Cr in pots were shifted to rhizobox-like system for 48h and organic acids were monitored in the mucilage dissolved from the plant root surface, mirroring rhizospheric solution. The results revealed that the Cr application at 1mM increased the shoot fresh and dry weight and root dry weight of Solanum nigrum, whereas the opposite was observed for Parthenium hysterophorus when compared with lower levels of Cr (0.5mM) or control treatment. In both plant species, Cr and Cl concentrations were increased while Ca, Mg and K concentrations in root, shoot and root exudates were decreased with increasing levels of Cr. Higher levels of Cr treatments enhanced the activities of SOD, POD and proline content in leaves of S. nigrum, whereas lower levels of Cr treatment were found to have stimulatory effects in P. hysterophorus. P. hysterophorus exhibited highest exudation of organic acid contents. With increasing levels of Cr treatments, citric acid concentration in root exudates increased by 35% and 44% in S. nigrum, whereas 20% and 76% in P. hysterophorus. Cr toxicity was responsible for the shoot growth reduction of S. nigrum and P. hysterophorus, however, shoot growth response was different at different levels of applied Cr. Consequently, Cr stress negatively altered the plant physiology and biochemistry. However, the enhanced antioxidant production, Cl uptake and root exudation are the physiological and biochemical indicators for the plant adaptations in biotic systems

The absorption coefficient (k), infinite reflectance (R), and scattering coefficient (s) were tabulated for five wavelengths and analyzed for statistical differences for seven weed species. The wavelengths were: 0.55-micrometer, 0.65-micrometers, 0.85-micrometer, 1.65-micrometers, and 2.20-micrometer. The R of common lambsquarters (Chenopodium album L.), Johnsongrass (Sorghum halepense (L.) Pers.), and annual sowthistle (Sonchus oleraceus L.) leaves at the 0.85-micrometer wavelength were significantly (p=0.05) higher than for sunflower (Heliantus annus L.), ragweed parthenium (Parthenium hysterophorus L.), or London rocket (Sisymbrium irio L.). Annual sowthistle had the largest k value, and Plamer amaranth (Amaranthus palmer S. Wats.) had the smallest k value at the 0.65 approximately chlorophyll absorption wavelength. In general, john-songress, ragweed parthenium, or London rocket had the largest s values among the five wavelengths, wereas annual sowthistle and plamar amaranth were usually lowest.

Motivation Factors for Female Entrepreneurship in Mexico

Directory of Open Access Journals (Sweden)

Martha Cantú Cavada

2017-09-01

Full Text Available Objective: The objective of this paper is to analyse motivation factors for female entrepreneurship in Mexico. In the proposed article, the authors discuss the factors which compelled women to start their enterprises in Mexico. Research Design & Methods: Based on in-depth interviews with female entrepreneurs and entrepreneurship experts, the authors show which factors motivated women to start their own business in Mexico. Findings: The study proves that women in Mexico are motivated by a combination of push and pull factors, where the majority of the factors are pull factors. The findings of the study help to conclude that female entrepreneurship development is influenced by different factors including the entrepreneurs’ personal traits, social and economic factors. Due to their conservative traditional attitude, risk adverse tendency, and non-cooperation of family members, etc. women entrepreneurs are sometimes deterred to start a business in Mexico. Implications & Recommendations: It is necessary to raise the awareness of different factors that promote female entrepreneurship in Mexico. Governmental programmes which support female entrepreneurship, business incubators, and networking could be very helpful for women when starting their own business. Contribution & Value Added: The originality of this work lies in studying motivational factors for female entrepreneurship in Mexico. The Mexican society faces a big revolution towards female entrepreneurship. Based on the change of family structure and traditions, women nowadays are having more opportunities to develop as entrepreneurs.

[Food security in Mexico].

Science.gov (United States)

Urquía-Fernández, Nuria

2014-01-01

An overview of food security and nutrition in Mexico is presented, based on the analysis of the four pillars of food security: availability, access, utilization of food, and stability of the food supply. In addition, the two faces of malnutrition in Mexico were analyzed: obesity and undernourishment. Data were gathered from the food security indicators of the United Nations's Food and Agriculture Organization, from the Mexican Scale of Food Security, and from the National Health and Nutrition Survey. Mexico presents an index of availability of 3 145 kilocalories per person per day, one of the highest indexes in the world, including both food production and imports. In contrast, Mexico is affected by a double burden of malnutrition: whereas children under five present 14% of stunt, 30% of the adult population is obese. Also, more than 18% of the population cannot afford the basic food basket (food poverty). Using perception surveys, people reports important levels of food insecurity, which concentrates in seven states of the Mexican Federation. The production structure underlying these indicators shows a very heterogeneous landscape, which translates in to a low productivity growth across the last years. Food security being a multidimensional concept, to ensure food security for the Mexican population requires a revision and redesign of public productive and social policies, placing a particular focus on strengthening the mechanisms of institutional governance.

Health technology assessment in Mexico.

Gómez-Dantés, Octavio; Frenk, Julio

2009-07-01

The history of health technology assessment (HTA) in Mexico is examined, starting with the efforts to incorporate this topic into the policy agenda and culminating with the recent creation of a specialized public agency. Information was gathered through a bibliographic search and interviews with actors involved in HTA in Mexico. HTA efforts were developed in Mexico since the mid-1980s with the participation both of academics and of policy makers, a relationship that eventually led to the creation of the Center for Technological Excellence within the Ministry of Health. Institutionalization of HTA in resource-constrained settings requires the development of a critical mass of researchers involved in this field, the implementation of information efforts, and the establishment of strong relationships between HTA experts and policy makers.

M. P. Moloeznik

2017-01-01

Full Text Available The article describes the problem of organized crime in modern Mexico. It addresses the activities of criminal clans, which profoundly evolved since the 1930s. The USMexican extensive border length and the stable demand for drugs in the United States leads to the continuous flow of illegal migrants and drugs from Mexico to the US and American firearms back to Mexico. First, the authors address the issue of interconnectedness of crime in the neighboring countries. Second, they describe the geographical distribution of crime activity. It shows the influence of organized crime on the political life oin Mexico and ways of its adaptation to law enforcement pressure, namely division and disaggregation. The authors state that the fight against organized crime was ineffective in Mexico in 2006-2012, because it ignored political and cultural realities, it used exclusively force and almost did not involve civil society. In addition, it only increased the level of violence in the country and contributed to the growth of corruption in the ranks of law enforcement. Moreover, it increased the level of violence in the country and contributed to the growth of corruption in the ranks of law enforcement. Many of its components had a pronounced «pre-election» character, aimed at attracting the voter with the promise of an «early and decisive victory» over criminals. The article proposes new approach to the problem of organized crime in Mexico. To start with, government should refuse to use unilateral, as well as politicized and opportunistic actions. The involvement of civic society is of ultimate importance.

First report of myxomatosis in Mexico.

Science.gov (United States)

Licón Luna, R M

2000-07-01

An outbreak of myxomatosis occurred between September and October 1993 on a rabbit farm in Punta Colnett (Ensenada, Baja California in northwestern Mexico, Transpeninsular Highway, km 128) and was confirmed by the Mexico-USA Commission for Prevention of Foreign Diseases of Animals (CPA). This represents the first officially confirmed case of the disease in Mexico. Like the cases in California (USA), the brush rabbit (Sylvilagus bachmani) seems to be the carrier of the virus, since serum samples from wild rabbits from different areas of the peninsula of Baja California were found to contain antibodies against the myxoma virus.

Glyphosate-Resistant Parthenium hysterophorus in the Caribbean Islands: Non Target Site Resistance and Target Site Resistance in Relation to Resistance Levels.

Directory of Open Access Journals (Sweden)

Enzo Bracamonte

2016-12-01

Full Text Available Glyphosate has been the most intensely herbicide used worldwide for decades, and continues to be a single tool for controlling weeds in woody crops. However, the adoption of this herbicide in a wide range of culture systems has led to the emergence of resistant weeds. Glyphosate has been widely used primarily on citrus in the Caribbean area, but a study of resistance in the Caribbean islands of Cuba and the Dominican Republic has never been carried out. Unfortunately, Parthenium hysterophorus has developed glyphosate-resistance in both islands, independently. The resistance level and mechanisms of different P. hysterophorus accessions (three collected in Cuba (Cu-R and four collected in the Dominican Republic (Do-R have been studied under greenhouse and laboratory conditions. In in vivo assays (glyphosate dose causing 50% reduction in above-ground vegetative biomass and survival, the resistance factor levels showed susceptible accessions (Cu-S≥Do-S, low-resistance accessions (Cu-R3Do-R2>Cu-R2>Do-R3>Do-R4>Cu-R3>>Cu-S≥Do-S. Glyphosate was degraded to aminomethylphosphonic acid, glyoxylate and sarcosine by >88% in resistant accessions except in Cu-R3 and Do-R4 resistant accessions (51.12 and 44.21, respectively, whereas a little glyphosate (<9.32% was degraded in both susceptible accessions at 96 h after treatment. There were significant differences between P. hysterophorus accessions in the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS activity enzyme with and without different glyphosate rates. The R accessions showed values of between 0.026 and 0.21 µmol µg-1 TSP protein min-1 basal EPSPS activity values with respect to the S (0.024 and 0.025 accessions. The same trend was found in the EPSPS enzyme activity treated with glyphosate, where a higher enzyme activity inhibition (glyphosate µM corresponded to greater resistance levels in P. hysterophorus accessions. One amino acid substitution was found at position 106 in EPSPS, consisting

Mexico: swapping crude for atoms

International Nuclear Information System (INIS)

Navarro, B.

1982-01-01

Mexico, considered the Saudi Arabia of the Western Hemisphere because of its proven and potential petroleum reserves, has surprised the world: it has embarked on the biggest nuclear-electric program in the Third World, only to postpone it days before scheduled approval of an international bidding (on which the atomic energy industry had pinned its hopes). A graph shows Mexican supplies of electricity by source with official projections to 1990. The point of entrance of the first nuclear reactor, originally scheduled for 1982, won't come onstream until 1983; and how nuclear-generated electricity grows close to 5% of the total in 1990. The big question is, will the future President of Mexico give the green light to the atomic megaproject. And if he does, how will Mexico deal with the serious logistics problems and grave ecological implications confronting the industry worldwide. In this issue, the author and Energy Detente touch on these questions and review the nuclear power status of Mexico, as well as addressing some of its global problems. Also presented in this issue is an update of the fuel price/tax series for the Western Hemisphere countries

Full Text Available Mexico-EC bilateral relations must be considered within the general relation ECLatin America which -as the author remarks, do not appear among EC's preferential relations.Latin America can benefit from the Generalized Preference System which is not discriminatory, without reciprocity and generalized, but has some restrictions: for some products as textile, leather or oil. This affects some Latin American countries and specifically Mexico.Mexico initiates its relation with the EC in 1960; in 1975 both parts sign the Agreement on Economic and Trade Cooperation which has been substituted by the new General Agreement on Cooperation signed on April26, 1991. A new factor that will condition this relation is the Free Trade Agreement recently signed between USA, Canada and Mexico.

A new Proposal to Mexico Valley Zonification

Flores-Estrella, H. C.; Yussim, S.; Lomnitz, C.

2004-12-01

The effects of the Michoacan earthquake (19th September, 1985, Mw 8.1) in Mexico City caused a significant change in the political, social and scientific history, as it was considered the worst seismic disaster ever lived in Mexico. Since then, numerous efforts have been made to understand and determine the parameters that caused the special features registered. One of these efforts had began on 1960 with the work by Marsal and Masari, who published the Mexico Valley seismological and geotechnical zonification (1969), based on gravimetric and shallow borehole data. In this work, we present a revision of the studies that proposed the zonification, a description of the valley geology, and basing on it we propose a new zonification for Mexico Valley.

Building the gas sector in Mexico

International Nuclear Information System (INIS)

Navarrete, J.E.

1996-01-01

Hydrocarbon reserves in Mexico, ranked 8th in the world, were discussed. On January 1, 1996, Mexico's hydrocarbon proven reserves were 62.1 billion barrels ( a decline of some 10 billion barrels since 1984). Of this 48.8 billion corresponded to crude oil and 13.3 billion to natural gas. Mexico's natural gas pipeline network includes 10,280 kilometres in transmission and 2,211 kilometres in distribution, concentrated along the Gulf of Mexico and in the central and northern regions of the country. A new regulatory framework for natural gas, passed in Congress in 1995, was outlined. The new amendments were designed to strengthen the natural gas industry through private investment in the storage, transportation and distribution of natural gas. Stages for third party access were identified. Increased North American regional integration by interconnections between Mexican, American and Canadian pipeline networks, and the effects of such integration on investments, were examined. figs

Martin Parr in Mexico: Does Photographic Style Translate?

Directory of Open Access Journals (Sweden)

Timothy R. Gleason

2011-11-01

Full Text Available This study analyzes Martin Parr’s 2006 photobook, Mexico. Parr is a British documentary photographer best known for a direct photographic style that reflects upon “Englishness.”Mexico is his attempt to understand this foreign country via his camera. Mexico, as a research subject, is not a problem to solve but an opportunity to understand a photographer’s work. Parr’s Mexico photography (technique, photographic content, and interest in globalization, economics, and culture is compared to his previous work to explain how Parr uses fashion and icons to represent a culture or class. This article argues Parr’s primary subjects, heads/hats, food, and Christs, are photographed without excessive aesthetic pretensions so that the thrust of Parr’s message about globalization can be more evident:Mexico maintains many of its traditions and icons while adopting American brands.

Gulf of Mexico deep-water

International Nuclear Information System (INIS)

Ott, G.L.

1998-01-01

The deepwater Gulf of Mexico, an emerging basin with 20 BBOE resource potential, was discussed. Technologies are advancing and development options are increasing within the Gulf of Mexico deepwater environment. Deepwater offers significant rate potentials leading to strong cash flows. The projected steep rate of resources captured in the next five years show that there is a short window of opportunity to establish a business position. The major production variables are development costs and cycle time. There is a definite market for Gulf of Mexico products because U.S. energy demand is expected to outstrip U.S. supply. Present infrastructure is capable of moving large volumes of gas into major U.S. markets, but with the large number of projects currently underway, especially in the United States, supply could exceed capacity. 1 tab., 16 figs

The economic impact of Sandia National Laboratories on central New Mexico and the state of New Mexico fiscal year 1997

International Nuclear Information System (INIS)

Lansford, R.R.; Nielsen, T.G.; Schultz, J.; Adcock, L.D.; Gentry, L.M.

1998-01-01

Sandia National Laboratories (SNL) was established in 1949 to perform the engineering development and ordnance responsibilities associated with nuclear weapons. By the early 1960's the facility had evolved into an engineering research and development laboratory and became a multiprogram laboratory during the 1970s. Sandia is operated for the US Department of Energy by the Sandia Corporation, a wholly-owned subsidiary of Lockheed Martin, Incorporated. For several years, the US Department of Energy (DOE) Albuquerque Operations Office (AL) and New Mexico State University (NMSU) have maintained an inter-industry, input-output model with capabilities to assess the impacts of developments initiated outside the economy such as federal DOE monies that flow into the state, on an economy. This model will be used to assess economic, personal income and employment impacts of SNL on central New Mexico and the state of New Mexico. For this report, the reference period is FY 1997 (October 1, 1996, through September 30, 1997) and includes two major impact analyses: the impact of SNL activities on central New Mexico and the economic impacts of SNL on the state of New Mexico. For purposes of this report, the central New Mexico region includes Bernalillo, Sandoval, Valencia, and Torrance counties. Total impact represents both direct and indirect respending by business, including induced effects (respending by households). The standard multipliers used in determining impacts results from the inter-industry, input-output models developed for the four-county region and the state of New Mexico. 6 figs., 10 tabs

Financing options in Mexico's energy industry

Energy Technology Data Exchange (ETDEWEB)

McKenna, J.J. (PricewaterhouseCoopers Securities, Houston, TX (United States))

1999-01-01

A series of brief notes accompanied this presentation which was divided into seven sections entitled: (1) capital markets update, (2) Mexican financial market update, (3) financing options in the energy industry, (4) the Venezuelan experience at La Apertura, (5) private and strategic equity alternatives, (6) Pricewaterhouse Coopers Securities, and (7) Mexico energy 2005 prediction. The paper focused on how the financial crisis and merger activity in Latin America will impact electricity reform in Mexico. It was noted that under Mexico's Policy Proposal for Electricity Reform of the Mexican Electricity Industry, the financial community will seek to back companies in power generation, transportation and distribution. The difficulty of financing government businesses undergoing privatization was also discussed with particular emphasis on the challenge of accepting political and regulatory risks. The Latin private equity market and Canadian investment in Mexico was also reviewed. Since NAFTA (North American Free Trade Agreement) went into affect in 1994, Canadian investment in Mexico has more than tripled. Canadian companies have invested more than C$1.7 billion in Mexico since NAFTA. Pricewaterhouse Coopers Securities is a global investment bank which sees large opportunities in the Mexican energy market. They predict that in five years, Mexico will experience a gradual liberalization of the oil and gas sector, and a full liberalization of the gas pipeline and distribution business and the power generation, transmission and distribution business. 3 figs.

Epidemic risk from cholera introductions into Mexico.

Moore, Sean M; Shannon, Kerry L; Zelaya, Carla E; Azman, Andrew S; Lessler, Justin

2014-02-21

Stemming from the 2010 cholera outbreak in Haiti, cholera transmission in Hispaniola continues with over 40,000 cases in 2013. The presence of an ongoing cholera outbreak in the region poses substantial risks to countries throughout the Americas, particularly in areas with poor infrastructure. Since September 9, 2013 nearly 200 cholera cases have been reported in Mexico, as a result of introductions from Hispaniola or Cuba. There appear to have been multiple introductions into Mexico resulting in outbreaks of 2 to over 150 people. Using publicly available data, we attempt to estimate the reproductive number (R) of cholera in Mexico, and thereby assess the potential of continued introductions to establish a sustained epidemic. We estimate R for cholera in Mexico to be between 0.8 to 1.1, depending on the number of introductions, with the confidence intervals for the most plausible estimates crossing 1. These results suggest that the efficiency of cholera transmission in some regions of Mexico is near that necessary for a large epidemic. Intensive surveillance, evaluation of water and sanitation infrastructure, and planning for rapid response are warranted steps to avoid potential large epidemics in the region.

Policies to reduce carbon emissions from Mexico

International Nuclear Information System (INIS)

Mendoza, Y.

1991-01-01

The two long-term scenarios carried out for Mexico attempt to paint a picture of carbon emissions and energy use in the year 2025. The scenarios reveal that Mexico's current energy path is not optimal; the energy-intensity indicators show an increasing reliance on petroleum products and electricity over the next 40 years. Thus, Mexico must embark on a program of energy conservation in the near future. Mexico recently has undertaken several energy conservation efforts. The Mexican government implemented a National Program for Energy Modernization. This program identifies the promotion of energy conservation in Mexico as one of its top priorities between 1990 and 1994. It incorporates a number of actions geared at improving energy conservation, including: establishing pricing policies which pay special attention to electricity tariffs; setting aside budget appropriations for energy-savings programs; carrying out an energy diagnosis in the transportation and industrial sectors; promoting cogeneration and new legislation in this field; setting efficiency standards for equipment; initiating a public education campaign to inform people about energy conservation; promoting the participation of research institutes and consulting firms in the research of the technological aspects of energy-saving measures; and creating agreement with industrial and commerce associations

2013-10-01

The Comprehensive Nuclear Test-Ban-Treaty (CTBT) is a treaty that prohibits all the nuclear explosions by anybody and in any place, either on the terrestrial surface, in the atmosphere, under the sea or underground. From the adoption of this Treaty by the United Nations, Mexico has had interest for its entrance in vigor, as integral part to assure the international peace. For this reason, our country signed the Treaty since it was open in September 24, 1996 and three years later ratified it, due to Mexico is part of the group of necessary countries for their entrance in vigor. During 13 years, the country has been committed and helped to the installation of monitoring stations, actions that allow the strengthening of the International System of Surveillance. The purpose of this work is to divulge the Treaty,its technologies and benefits; and also to diffuse the works realized by Mexico regarding the radionuclides monitoring station and noble gases both certified ones for the CTBT. Besides the radionuclides technology, Mexico has taken charge of the installation and operation of the seismic stations and hydro-acoustics that have been certified too. The radionuclides station Rn-44 located in Guerrero Negro, BCS has two technologies, an automated sampler of suspended particles in air brand Cinderella/ARAME and a noble gases system Sauna used for the particles detection of radioactive material gamma emitting and Xenon radioisotopes product of nuclear assays. Both technologies are transmitting data in real time to the International Center of Data. These technologies are shown in this work. (Author)

International Nuclear Information System (INIS)

2016-01-01

Immersed in the global price instability of fossil fuels and with an upsurge in renewables as the agent for development, countries like Mexico, that largely depend on this resource to generate income and whose national electrical energy generation mainly comes from these fuels, find themselves obliged to take decisions that allow them to maintain their appeal compared to other emerging markets. In this decision-making process, Mexico has been slow to implement its long-awaited Energy Reform that incentivises direct foreign investment and avoids the monopolies that have until recently prevailed in the Mexican energy and electricity sector.

Neuropsychology in Mexico.

Science.gov (United States)

Ostrosky Shejet, Feggy; Velez Garcia, Alicia

2016-11-01

This invited paper explores the diverse pathways that have led to the development of neuropsychology in Mexico. The authors conducted a review of the literature and their own experiences to describe the seminal events and people relevant to the development of this area of research and practice. The master's degree is the usual level of educational attainment for those who wish to practice clinical neuropsychology. As of now, there is not a board certification process in neuropsychology, although there is one in clinical psychology. Neuropsychology and other mental health disciplines in Mexico and Latin America have historically been poorly funded, and have lacked optimal means of communication as to research findings and clinical initiatives and standards. However, there is reason to think that this will be improved upon in coming years.

Mobile exhibition in Mexico

Since January this year, a mobile atomic energy exhibition has been touring the principal cities of Mexico. In organizing this exhibition, the National Nuclear Energy Commission of Mexico was assisted by the International Atomic Energy Agency which has placed its second mobile radioisotope laboratory at the disposal of the Mexican authorities. In many States of the Republic, the visit of the mobile laboratory has given a powerful impetus to atomic training and research. Universities have made use of the laboratory for the training of young scientists in the basic isotope techniques. As a sequel to the work initiated with its aid, some universities are planning to start regular training courses in this field. The laboratory, which is a gift to the Agency from the United States, has been put to its first assignment in Mexico. It will shortly be sent to Argentina for a period of six months for use in training courses. IAEA's first mobile radioisotope unit, also donated by the United States, has been used for training purposes in Austria, the Federal Republic of Germany, Greece and Yugoslavia, and has now been sent to the Far East

West Nile virus (WNV) has caused disease in humans, equids, and birds at lower frequency in Mexico than in the United States. We hypothesized that the seemingly reduced virulence in Mexico was caused by attenuation of the Tabasco strain from southeastern Mexico, resulting in lower viremia than that caused by the Tecate strain from the more northern location of Baja California. During 2006-2008, we tested this hypothesis in candidate avian amplifying hosts: domestic chickens, rock pigeons, house sparrows, great-tailed grackles, and clay-colored thrushes. Only great-tailed grackles and house sparrows were competent amplifying hosts for both strains, and deaths occurred in each species. Tecate strain viremia levels were higher for thrushes. Both strains produced low-level viremia in pigeons and chickens. Our results suggest that certain avian hosts within Mexico are competent for efficient amplification of both northern and southern WNV strains and that both strains likely contribute to bird deaths.

Radon-in-soil concentration levels in Mexico

International Nuclear Information System (INIS)

Segovia, N.; Tamez, E.; Mena, M.

1992-01-01

Radon-in-soil surveys in Mexico have been carried out since 1974 both for uranium prospecting and to correlate mean values of the gas emanation with local telluric behaviour. The mapping covers the northern uranium mining region, the Mexican Neovolcanic Belt, the coastal areas adjacent to the zone of subduction of the Cocos Plate under the North American Plate, some of the active volcanoes of Southern Mexico and several sedimentary valleys in Central Mexico. Recording of 222 Rn alpha decay is systematically performed with LR115 track detectors. Using mean values averaged over different observation periods at fixed monitoring stations, a radon-in-soil map covering one third of the territory of Mexico is presented. The lowest mean values occur in areas associated with active volcanoes. The highest levels are found in uranium ore zones. Intermediate values are obtained in regions with enhanced hydrothermal activity and stations associated with intrusive rocks. (author)

Mexico SimSmoke: how changes in tobacco control policies would impact smoking prevalence and smoking attributable deaths in Mexico.

Fleischer, Nancy L; Thrasher, James F; Reynales-Shigematsu, Luz Myriam; Cummings, K Michael; Meza, Rafael; Zhang, Yian; Levy, David T

2017-07-01

We examined the effect of tobacco control policies in Mexico on smoking prevalence and smoking-related deaths using the Mexico SimSmoke model. The model is based on the previously developed SimSmoke simulation model of tobacco control policy, and uses population size, smoking rates and tobacco control policy data for Mexico. It assesses, individually, and in combination, the effect of six tobacco control policies on smoking prevalence and smoking-related deaths. Policies included: cigarette excise taxes, smoke-free laws, anti-smoking public education campaigns, marketing restrictions, access to tobacco cessation treatments and enforcement against tobacco sales youth. The model estimates that, if Mexico were to adopt strong tobacco control policies compared to current policy levels, smoking prevalence could be reduced by 30% in the next decade and by 50% by 2053; an additional 470,000 smoking-related premature deaths could be averted over the next 40 years. The greatest impact on smoking and smoking-related deaths would be achieved by raising excise taxes on cigarettes from 55% to at least 70% of the retail price, followed by strong youth access enforcement and access to cessation treatments. Implementing tobacco control policies in Mexico could reduce smoking prevalence by 50%, and prevent 470,000 smoking-related deaths by 2053.

Dengue is an acute febrile illness caused by any of four dengue virus types (DENV-1-4). DENVs are transmitted by mosquitos of the genus Aedes (1) and are endemic throughout the tropics (2). In 2010, an estimated 390 million DENV infections occurred worldwide (2). During 2007-2013, a total of three to 10 dengue cases were reported annually in Arizona and all were travel-associated. During September-December 2014, coincident with a dengue outbreak in Sonora, Mexico, 93 travel-associated dengue cases were reported in Arizona residents; 70 (75%) cases were among residents of Yuma County, which borders San Luis Río Colorado, Sonora, Mexico. San Luis Río Colorado reported its first case of locally acquired dengue in September 2014. To investigate the temporal relationship of the dengue outbreaks in Yuma County and San Luis Río Colorado and compare patient characteristics and signs and symptoms, passive surveillance data from both locations were analyzed. In addition, household-based cluster investigations were conducted near the residences of reported dengue cases in Yuma County to identify unreported cases and assess risk for local transmission. Surveillance data identified 52 locally acquired cases (21% hospitalized) in San Luis Río Colorado and 70 travel-associated cases (66% hospitalized) in Yuma County with illness onset during September-December 2014. Among 194 persons who participated in the cluster investigations in Yuma County, 152 (78%) traveled to Mexico at least monthly during the preceding 3 months. Four (2%) of 161 Yuma County residents who provided serum samples for diagnostic testing during cluster investigations had detectable DENV immunoglobulin M (IgM); one reported a recent febrile illness, and all four had traveled to Mexico during the preceding 3 months. Entomologic assessments among 105 households revealed 24 water containers per 100 houses colonized by Ae. aegypti. Frequent travel to Mexico and Ae. aegypti colonization indicate risk for local

In this work the analysis of strengths, opportunities, vulnerabilities and threats (SOVT) of the nuclear industry in Mexico is presented. This industry presents among its strengths that Mexico is a highly electrified country and has a good established normative mark of nuclear security. Although the Secretaria de Energia in Mexico, with base to the exposed in the Programa Sectorial de Energia 2007-2012, is analyzing the convenience of the generation starting from this source, considering the strong technological dependence of the exterior and the limited federal budget dedicated to this field. As a result of the analysis of the SOVT matrix, were found a great number of strengths that threats, although the vulnerabilities list is major to the strengths, the opportunities list is the bigger. Therefore, the nuclear industry can be a sustainable industry, taking the necessary decisions and taking advantage of the detected opportunities. (Author)

Many patients with dermatitis over photo-exposed body areas are positive to many contact allergens and have a pre-existing allergic contact dermatitis. This study included patients who presented to a tertiary centre in India with dermatitis on photo-exposed body areas suspected of chronic actinic dermatitis. Their detailed histories were recorded and cutaneous and systemic examinations were performed. Patch testing was done in all the patients and photo-patch testing was carried out in 86 patients. Altogether 101 patients were included (69 males, 32 females). The most common presentation was lichenified hyperpigmented plaques on the photo-exposed sites. Photosensitivity was recorded in 64 (63%) patients and summer exacerbation in 52 (52%). Exposure to the Parthenium hysterophorus weed was recorded in 70 (69%) patients, 27 (26.7%) had a history of hair dye application and 20 (20%) had a history of atopy. Photo-patch test was positive in 11 (12.8%) patients and patch testing was positive in 71 (70%). Parthenium hysterophorus was the most common allergen implicated and was positive in three (4%) photo-patch and 52 (52%) patch tests. Other positive photo-patch test allergens were perfume mix, balsam of Peru, thiuram mix, Compositae mix and promethazine hydrochloride. Other common patch test allergens were parthenolide, colophony, fragrance mix and p-phenylenediamine (PPD) base. In the Indian population parthenium and perfume mix are the most common photoallergens in patients with dermatitis over photo-exposed areas, while parthenium, colophony, fragrance mix and PPD are the common positive allergens. © 2016 The Australasian College of Dermatologists.

Return Migration to Mexico: Does Health Matter?

Science.gov (United States)

Arenas, Erika; Goldman, Noreen; Pebley, Anne R; Teruel, Graciela

2015-12-01

We use data from three rounds of the Mexican Family Life Survey to examine whether migrants in the United States returning to Mexico in the period 2005-2012 have worse health than those remaining in the United States. Despite extensive interest by demographers in health-related selection, this has been a neglected area of study in the literature on U.S.-Mexico migration, and the few results to date have been contradictory and inconclusive. Using five self-reported health variables collected while migrants resided in the United States and subsequent migration history, we find direct evidence of higher probabilities of return migration for Mexican migrants in poor health as well as lower probabilities of return for migrants with improving health. These findings are robust to the inclusion of potential confounders reflecting the migrants' demographic characteristics, economic situation, family ties, and origin and destination characteristics. We anticipate that in the coming decade, health may become an even more salient issue in migrants' decisions about returning to Mexico, given the recent expansion in access to health insurance in Mexico.

Brucellosis is one of the most frequent zoonosis in most parts of the world. This zoonosis remains a great problem to public health in developing countries, although developed countries have successfully controlled it. Mexico still shows a high annual brucellosis incidence in humans; thus, the country is considered around the world as an endemic brucellosis country. To describe the connection/association between this zoonosis and the current epidemiological situation in the Mexican population. Perusal of research reports, epidemiological studies and veterinarian reviews performed in Mexico, using data bases such as PubMed, Thompson Reuters, Mesh research. The risk of infection by Brucella in Mexico is associated with the consumption of unpasteurized dairy products, mainly fresh cheeses.

Early radioisotope uses in Mexico

International Nuclear Information System (INIS)

Segovia, N.; Tejera, A.; Bulbulian, S.; Palma, F.

1991-10-01

Mexico is traditionally a mining country and the first information about the presence of uranium is related to mine exploitation. Around 1945 when uranium became economically important, a rumor had spread that large amounts of black ceramics from Oaxaca were being purchased and sent abroad because of its assumed high uranium content. It was only in 1949 when minerals containing thorium and uranium were declared by law as 'National Reserves'. In those years a radium emanation plant was installed at the 'Hospital General' in Mexico City with the main purpose of carrying out radon seed implantation in tumors. In the fifties a radium dial painting facility was operating in the city of Toluca some 70 km from Mexico City. In 1955, when the National Commission of Nuclear Energy (CNEN) was founded by a government decree, two main activities were in sight: a training program on 'Radioisotope Techniques and Nuclear Instrumentation' and the creation of specialized laboratories. In this paper a general description of these events and undertakings spanning the decades 1940 to 1970 is given. (Author)

2002-01-01

This paper presents a historical overview of the energy sector in Mexico, an important player in the world energy market, whose trade and market policies support economic development and foreign investment. Trade, commerce and investment between Canada and Mexico has been increasing steadily ever since the North American Free Trade Agreement (NAFTA) came into effect in January 1994. TransAlta Corporation and Westcoast Energy Inc. are two very active investors in the energy sector. Westcoast has invested in increasing natural gas and oil production from the Cantarell field in the Gulf of Mexico through the Campeche Natural Gas Compression Service Project and the Cantarell Nitrogen Plant. TransAlta has invested in two natural gas fired power plants which are both expected to be in service for the second quarter of 2003. These include the 252 MW Campeche facility and the 259 MW Chihuahua facility. Mexico has proven crude oil reserves of 27 billion barrels, proven natural gas reserves of 30 tcf, and in 2000 had a crude oil production of 3.4 mmbl/d, of which half was exported. The energy sector in Mexico may need about $120 billion of investment by 2010, of which half will be used for crude oil exploration and production, transportation and refining and the other half for natural gas exploration and production, transportation and distribution and power generation. Recently, the Mexican government embarked on two initiatives. The first to increase the productivity and profitability of PEMEX, the largest corporation in Mexico and one of the largest in the world, and to allow a form of private investment in the development of non-associated natural gas fields. This paper discussed the significance of the Multiple Service Contracts (MSC) program which involves domestic and international petroleum exploration and development. It also discussed forms of business organizations, taxation and structuring, financial issues, employment and the North American Free Trade Agreement

Social manifestations of abortion stigma depend upon cultural, legal, and religious context. Abortion stigma in Mexico is under-researched. This study explored the sources, experiences, and consequences of stigma from the perspectives of women who had had an abortion, male partners, and members of the general population in different regional and legal contexts. We explored abortion stigma in Mexico City where abortion is legal in the first trimester and five states-Chihuahua, Chiapas, Jalisco, Oaxaca, and Yucatán-where abortion remains restricted. In each state, we conducted three focus groups-men ages 24-40 years (n = 36), women 25-40 years (n = 37), and young women ages 18-24 years (n = 27)-and four in-depth face-to-face interviews in total; two with women (n = 12) and two with the male partners of women who had had an abortion (n = 12). For 4 of the 12 women, this was their second abortion. This exploratory study suggests that abortion stigma was influenced by norms that placed a high value on motherhood and a conservative Catholic discourse. Some participants in this study described abortion as an "indelible mark" on a woman's identity and "divine punishment" as a consequence. Perspectives encountered in Mexico City often differed from the conservative postures in the states.

A perspective of food safety laws in Mexico.

Leon, Marco A; Paz, Esmeralda

Mexico, with a population of 112 million, is one of the most interesting countries in the world with regard to food, hunger, domestic food consumption, tourism and international trade, and it deserves an in-depth study to explain the status of its food safety laws. Mexico has a strong and stable emerging economy and is the second country worldwide with regard to the number of free-trade agreements. Nevertheless, more than half the population lives in poverty. However, Mexico is a huge market for food consumption because, in addition to its own population, it receives 20 million international tourists per year. So, multi-national food companies have representatives and facilities throughout the country. This scenario may explain the evolution of food safety laws in Mexico, as well as the challenges that must be faced in order to achieve food safety. © 2013 Society of Chemical Industry.

In this report present a general overview of energy trends and objectives of policy for Mexico, in the context of sustainable development. The work is divided in two main parts: the first one presents trends in energy use and potential, energy sector reform, social and economics indicators and revision of efficiency and renewable energy. The second part discusses options and instruments of energy politics for the country in regard of the sustainable development. The energy is central to concerns of sustainable development, affecting economic; the local and global environment, and social problems as poverty, population, health and education. Mexico should promote political energy that permit the fulfillment the energy requirements while developing strategies that help to alleviate the social problems and productivity, based on lesser environmental impacts. [Spanish] Este reporte presenta una vision sobre las tendencias energeticas de Mexico y plantea prioridades y objetivos de politica para el pais, en el contexto de desarrollo sustentable. El trabajo muestra dos partes principales: la primera seccion presenta tendencias en el uso de energia, potenciales energeticos e indicadores economicos y sociales, ademas de una revision de eficiencias y politicas de energias renovables. La segunda parte discute opciones, instrumentos y restricciones en el contexto del desarrollo energetico sustentable en el pais. La energia es un elemento central en el desarrollo ya que esta relacionado con la economia, el ambiente local y global y aspectos sociales como pobreza, poblacion, salud y educacion. Esto obliga en Mexico a promover politicas que permitan la cobertura de los requerimientos energeticos, las cuales deben desarrollarse de manera conjunta con estrategias, para ayudar a disminuir los problemas, productivos y sociales con menores impactos ambientales.

Molecular Relationship between Strains of M. bovis from Mexico and Those from Countries with Free Trade of Cattle with Mexico.

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to identify relationships between spoligotypes of M. bovis from cattle in Mexico and those reported in countries with free trade of cattle with Mexico: Australia, Canada, New Zealand and the United States of America. Mexican spoligotypes were obtained from isolates collected from cattle in different parts of the country. Spoligotypes from Canada and New Zealand were obtained from different reports in the literature. Those from the United States were obtained from the database of the National Veterinary Services Laboratory in APHIS-USDA. In order to perform the analysis in a single data set, spoligotypes were all converted to binary data and classified according to www.mbovis.org or www.pasteur-guadeloupe.fr:8081. Epidemiologic information included country and species infected. From 3,198 isolates, 174 different spoligotypes were obtained, 95 were orphans. Ninety one percent of the isolates came from the Unites States (n = 1,609 and Mexico (n = 1,323. Spoligotype SB0265 is shared between Canada and the United States in cattle and wildlife. Six spoligotypes, SB0673, SB0121, SB0145, SB0971, SB0140 and SB1165, were frequent in cattle and wildlife in the United States and cattle in Mexico, suggesting wide exchange of strains. Spoligotype SB0669 was found only in Mexico. Spoligotype SB0140 was the most common in Australia and the sixth in the United States and Mexico. In a phylogenetic analysis, spoligotype SB0140 appears as the oldest spoligotype in the data set, suggesting this as the ancestral spoligotype for all spoligotypes in the five countries. Some spoligotypes are shared by animals and humans, corroborating the zoonotic importance of M. bovis.

2015-01-01

Excess body weight (overweight and obesity) is currently recognized as one of the most important challenges of public health in the world, given its size, speed of growth and the negative effect it has on the health of the population that suffers. Overweight and obesity significantly increases the risk of chronic no communicable diseases, premature mortality and the social cost of health. An estimated 90 % of cases of type 2 diabetes mellitus attributable to overweight and obesity. Today, Mexico is second global prevalence of obesity in the adult population, which is ten times higher than that of countries like Japan and Korea. With regard to children, Mexico ranks fourth worldwide obesity prevalence, behind Greece, USA and Italy. In our country, over 70 % of the adult population, between 30 and 60 years are overweight. The prevalence of overweight is higher in men than females, while the prevalence of obesity is higher in women than men. Until 2012, 26 million Mexican adults are overweight and 22 million obese, which represents a major challenge for the health sector in terms of promoting healthy lifestyles in the population and development of public policies to reverse this scenario epidemiology. Mexico needs to plan and implement strategies and action cost effective for the prevention and control of obesity of children, adolescents and adults. Global experience shows that proper care of obesity and overweight, required to formulate and coordinate multisectoral strategies and efficient for enhancing protective factors to health, particularly to modify individual behavior, family and community.

Designing Distributed Generation in Mexico

Energy Technology Data Exchange (ETDEWEB)

Linvill, Carl [Regulatory Assistance Project, Montepelier, VT (United States); Brutkoski, Donna [Regulatory Assistance Project, Montepelier, VT (United States)

2017-05-15

Mexico's energy reform will have far-reaching effects on how people produce and consume electricity in the country. Market liberalization will open the door to an increasing number of options for Mexican residential, commercial, and industrial consumers, and distributed generation (DG), which for Mexico includes generators of less than 500 kilowatts (kW) of capacity connected to the distribution network. Distributed generation is an option for consumers who want to produce their own electricity and provide electricity services to others. This report seeks to provide guidance to Mexican officials on designing DG economic and regulatory policies.

Catch-up Growth Followed by Stagnation: Mexico, 1950-2010

OpenAIRE

Timothy J. Kehoe; Felipe Meza

2011-01-01

In 1950 Mexico entered an economic takeoff and grew rapidly for more than 30 years. Growth stopped during the crises of 1982-1995, despite major reforms, including liberalization of foreign trade and investment. Since then growth has been modest. We analyze the economic history of Mexico 1877-2010. We conclude that the growth 1950-1981 was driven by urbanization, industrialization, and education and that Mexico would have grown even more rapidly if trade and investment had been liberalized so...

Renewable energy for productive uses in Mexico

Energy Technology Data Exchange (ETDEWEB)

Hanley, C.

1997-12-01

This paper describes a USAID/USDOE sponsored program to implement renewable energy in Mexico for productive uses. The objectives are to expand markets for US and Mexican industries, and to combat global climate change - primarily greenhouse gas emissions. The focus is on off-grid applications, with an emphasis on developing the institution structure to support the development of these industries within the country. Agricultural development is an example of the type of industry approached, where photovoltaic and wind power can be used for water pumping. There are hundreds of projects under review, and this interest has put renewables as a line item in Mexico`s rural development budget. Village power projects are being considered in the form of utility partnerships.

Abortion Legalization and Childbearing in Mexico.

Science.gov (United States)

Gutiérrez Vázquez, Edith Y; Parrado, Emilio A

2016-06-01

In 2007 abortion was legalized in the Federal District of Mexico, making it the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. We examine metropolitan-area differences in overall and parity-specific childbearing, as well as the age pattern of childbearing between 2000 and 2010 to identify the contribution of abortion legalization to fertility in Mexico. Our statistical specification applies difference-in-difference regression methods that control for concomitant changes in other socioeconomic predictors of fertility to assess the differential influence of the law across age groups. In addition, we account for prior fertility levels and change to better separate the effect of the law from preceding trends. Overall, the evidence suggests a systematic association between abortion legalization and fertility. The law appears to have contributed to lower fertility in Mexico City compared to other metropolitan areas and prior trends. The influence is mostly visible among women aged 20-34 in connection with the transition to first and second child, with limited impact on teenage fertility. There is some evidence that its effect might be diffusing to the Greater Mexico City Metropolitan area. © 2016 The Population Council, Inc.

New Mexico waste plant sits idle amid controversy

International Nuclear Information System (INIS)

Lovejoy, L.A. Jr.

1994-01-01

The Department of Energy (DOE) hopes to permanently dispose of radioactive waste from its weapons program at a Waste Isolation Pilot Plant about 26 miles from Carlsbad, New Mexico. The plant has been plagued by problems, according to Lindsay A. Lovejoy, Jr., an assistant attorney general of New Mexico. Among them are cracks in the walls of some of the underground rooms slated for storage of radioactive waste. Meanwhile, above-ground problems involve DOE's struggle toward regulatory compliance. The Environmental Protection Agency (EPA), under the Resource Conservation Recovery Act, has assumed a regulatory role over DOE's radioactive waste-disposal efforts, which is a new role for the agency. Lovejoy proposes that EPA, in its regulation of the New Mexico plant, develop compliance criteria and involve DOE and the public in ongoing open-quotes dialogue aimed at ferreting out any and all problems before a single scrap of radioactive waste is deposited into the earth beneath new Mexico.close quotes

To estimate the magnitude of diabetes in Mexico, as well as discuss alternative policies to face it appropriately. Descriptive analysis of the National Health and Nutrition Survey 2012, using reported information on previous diagnosis of diabetes from adults and adolescents. From all adults 20 years and older in Mexico, 9.17% has been diagnosed with diabetes, presenting an important geographical heterogeneity, ranging from 5.6% in the southern state of Chiapas, to 12.3% in Mexico City. Of all people with diabetes, 46.95% also have been diagnosed with hypertension, 4.47% has had a stroke, and 54.46%, reported family background of diabetes. Regarding adolescents, 0.68% has been already diagnosed with diabetes. The burden of diabetes in Mexico and the fact that is a preventable condition, calls to strengthen the health sector strategies to face it. The negative effect it has on the quality of life makes diabetes a priority for the health sector.

1996-07-01

The projections of demand of energy for Mexico, in the global and regional scope, for period 1992-2020 are presented. The projections are based on the use of a simulation model built in the University Program of Energy of the Universidad Nacional Autonoma de Mexico (UNAM), which allows to project the demand in the short and medium term of the primary and final energy. Projections of the demands of energy or for fuels by sectors and subsectors are obtained in accordance with different scenarios of growth. Particularly the demand of natural gas is analyzed, both, as energy and as raw material for the petrochemical industry, and as fuel oil, under different scenarios of economic growth and policies of environmental character. [Spanish] Se presentan las proyecciones de demanda de energia para Mexico, en el ambito global y regional, para el periodo 1992-2020. Las proyecciones estan basadas en el uso de un modelo de simulacion construido en el Programa Universitario de Energia de la Universidad Nacional Autonoma de Mexico (UNAM), el cual permite proyectar la demanda de energia primaria y final en el corto y mediano plazos. Se obtienen proyecciones de las demandas de energia por sectores y subsectores o por combustibles de acuerdo con diferentes escenarios de crecimiento. En particular se analiza la demanda de gas natural, tanto como energetico como materia prima para la petroquimica, y combustoleo bajo diferentes escenarios de crecimiento economico y politicas de caracter ambiental.

The chewing lice (Insecta: Phthiraptera: Amblycera and Ischnocera) of Mexico have been little studied and many publications include isolated records. This paper summarizes current knowledge of chewing lice recorded from Mexico resulting from an exhaustive search of the literature published from 1866 to 2017. We found 342 louse species associated with 206 bird and 28 mammal species. As a result, we provide a checklist of the chewing lice recorded from Mexico, including a host-parasite list and their geographical distribution within the country.

2015-01-01

Canine parvovirus (CPV) is one of the most common infectious agents related to high morbidity rates in dogs. In addition, the virus is associated with severe gastroenteritis, diarrhea, and vomiting, resulting in high death rates, especially in puppies and nonvaccinated dogs. To date, there are 3 variants of the virus (CPV-2a, CPV-2b, and CPV-2c) circulating worldwide. In Mexico, reports describing the viral variants circulating in dog populations are lacking. In response to this deficiency, a total of 41 fecal samples of suspected dogs were collected from October 2013 through April 2014 in the Veterinary Hospital of the University of Guadalajara in western Mexico. From these, 24 samples resulted positive by polymerase chain reaction, and the viral variant was determined by restriction fragment length polymorphism. Five positive diagnosed samples were selected for partial sequencing of the vp2 gene and codon analysis. The results demonstrated that the current dominant viral variant in Mexico is CPV-2c. The current study describes the genotyping of CPV strains, providing valuable evidence of the dominant frequency of this virus in a dog population from western Mexico. © 2014 The Author(s).

Severe fungal infections, particularly those caused by Candida spp, have increased in recent decades and are associated with an extremely high rate of morbidity and mortality. Since plants are an important source of potentially bioactive compounds, in this work the antifungal activity of the methanol extracts of 10 plants (Acacia rigidula, Buddleja cordata, Cephalanthus occidentalis, Juglans nigra, Parkinsonia aculeata, Parthenium hysterophorus, Quercus canbyi, Ricinus communis, Salvia coccinea and Teucrium bicolor) were evaluated. The activity was evaluated according to the micro dilution assay described in CLSI M27-A protocol using some clinical isolates of different species of Candida (C. albicans, C. parapsilosis, C. tropicalis, C. krusei and C. glabrata). All extracts showed MIC values < 31.25μg/mL against at least one of the strains used, which is very interesting because it was crude extracts. Acacia rigidula (0.93-3.75μg/mL) and Quercus canbyi (0.93-7.5μg/mL) had antifungal activity against 7 strains with MIC values <8μg/mL in all cases. Furthermore excerpts activity against Mycobacterium tuberculosis (strain H37rv) was evaluated. Only Salvia coccinea and Teucrium bicolor showed MIC values125μg/mL by the method of MABA.

Mexico City is one of the most populated cities in the world with almost 22 million inhabitants, located at an altitude of 2200 m. The old city was founded on an ancient lake and the zone is known by its high seismicity; indoor radon determination is an important public health issue. In this paper the data of indoor radon levels in Mexico City, measured independently by two research groups, both using Nuclear Track Detector systems but different methodologies, are correlated. The measurements were done during similar exposure periods of time, at family houses from the political administrative regions of the city. The results indicate a correlation coefficient between the two sets of data of R=0.886. Most of the differences between the two sets of data are inherent to houses having extreme (very high or very low indoor radon) included in the statistics of each group. The total average indoor radon found in Mexico City considering the two methods was 87Bqm{sup -3}.

Upper Mantle Discontinuities Underneath Central and Southern Mexico

Science.gov (United States)

Perez-Campos, X.; Clayton, R. W.

2011-12-01

Central and southern Mexico are affected by the subduction of Cocos plate beneath North American plate. The MesoAmerican Subduction Experiment (MASE) and the Veracruz-Oaxaca (VEOX) project have mapped the geometry of the Cocos slab. It is characterized in central Mexico by a shallow horizontal geometry up to ~300 km from the trench, then it dives steeply (70°) into the mantle, to its apparent end at 500 km depth. In contrast, some 400 km to the south, the slab subducts smoothly, with a dip angle of ~26° to a depth of 150 km. We use receiver functions from teleseismic events, recorded at stations from MASE, VEOX, and the Servicio Sismológico Nacional (SSN, Mexican National Seismological Service) to map the upper mantle discontinuities and properties of the transition zone in central and southern Mexico. We also use data from the Mapping the Rivera Subduction Zone (MARS) Experiment to get a complete picture of the subduction regime in central Mexico and compare the mantle transition zone in a slab tear regime. The 410 discontinuity shows significant variation in topography in central Mexico, particularly where the slab is expected to reach such depth. The 660 discontinuity shows a smoother topography, indicating that the slab does not penetrate this far down. The results will be compared with a ridge regime in the Gulf of California.

Establishing a Water Resources Resilience Baseline for Mexico City

Science.gov (United States)

Behzadi, F.; Ray, P. A.

2017-12-01

There is a growing concern for the vulnerability of the Mexico City water system to shocks, and the capacity of the system to accommodate climate and demographic change. This study presents a coarse-resolution, lumped model of the water system of Mexico City as a whole, designed to identify system-wide imbalances, and opportunities for large-scale improvements in city-wide resilience through investments in water imports, exports, and storage. In order to investigate the impact of climate change in Mexico City, the annual and monthly trends of precipitation and temperature at 46 stations near or inside the Mexico City were analyzed. The statistical significance of the trends in rainfall and temperature, both over the entire period of record, and the more recent "climate-change-impacted period" (1970-2015), were determined using the non-parametric Mann-Kendall test. Results show a statistically significant increasing trend in the annual mean precipitation, mean temperature, and annual maximum daily temperature. However, minimum daily temperature does not appear to be increasing, and might be decreasing. Water management in Mexico City faces particular challenges, where the winter dry season is warming more quickly than the wet summer season. A stress test of Mexico City water system is conducted to identify vulnerabilities to changes in exogenous factors (esp., climate, demographics, land use). Following on the stress test, the relative merits of adaptation options that might improve the system's resilience and sustainability will be assessed.

The impact of taxation on tobacco consumption in Mexico.

The price of cigarettes to consumers in Mexico, and Latin America in general, remains low in comparison with other regions of the world. In Mexico, taxes represented 59% of the total price of cigarettes in 2006, compared to 75% or more in many high-income countries. The feasibility of raising taxes on cigarettes in Mexico--to both discourage consumption and increase revenues--is an important policy question. Using household survey data, we undertake a pooled cross-sectional analysis of the demand for cigarettes in Mexico. We use a two-part model to estimate the price elasticity of cigarettes. This model controls for the selection effect that arises from the fact that the impact of price on the decision to smoke or not is estimated using all households in the dataset. The results indicate that price is a significant factor in household decisions concerning smoking and the number of cigarettes smoked. Holding other factors constant, our simulations show that a 10% increase in the cigarette tax in Mexico--calculated as a percentage of the price--yields a 12.4% increase in the price to the consumer, a 6.4% decrease in consumption of cigarettes and a 15.7% increase in the revenue yielded by the tax. In Mexico, there are strong arguments for increasing cigarette taxes. Revenue raised could be used to further prevent tobacco consumption and to finance current funding shortages for the treatment of diseases related to smoking.

Blooms of the toxic marine dinoflagellate Karenia brevis cause massive fish kills and other public health and economic problems in coastal waters throughout the Gulf of Mexico [Steidinger, 2009]. These harmful algal blooms (HABs) are a gulf-wide problem that require a synoptic observing system for better serving decision-making needs. The major nutrient sources that initiate and maintain these HABs and the possible connectivity of blooms in different locations are important questions being addressed through new collaborations between Mexican and U.S. researchers and government institutions. These efforts were originally organized under the U.S./Mexico binational partnership for the HABs Observing System (HABSOS), led by the U.S. Environmental Protection Agency's Gulf of Mexico Program (EPAGMP) and several agencies in Veracruz, Mexico, since 2006. In 2010 these efforts were expanded to include other Mexican states and institutions with the integrated assessment and management of the Gulf of Mexico Large Marine Ecosystem (GoMLME) program sponsored by the Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), and the National Oceanic and Atmospheric Administration (NOAA).

The growth of gerontology and geriatrics in Mexico: Past, present, and future.

Science.gov (United States)

Rivera-Hernandez, Maricruz; Flores Cerqueda, Sergio; García Ramírez, José Carlos

2017-01-01

Life expectancy is increasing in Mexico, creating new opportunities and challenges in different areas, including gerontology and geriatric education and research. Although in the European Union there are more than 3,000 institutions that focus on aging research, in Latin America there are only 250 programs where theoretical and practical knowledge is taught. In Mexico, the number of institutions that offer gerontology and geriatric education is relatively small. One of the major concerns is that Mexico is not adequately prepared to optimally deal with the aging of its population. Thus, the main challenge that Mexico faces is to train practitioners, researchers, and policy makers to be able to respond to the aging priorities of this country. The goal of this review is to investigate the literature regarding 60 years in the fields of gerontology and geriatrics in Mexico. Even when programs have evolved within the past decades, there are some challenges to gerontological and geriatric education and aging research in Mexico. The implications for Mexico are discussed, as well as opportunities for moving these fields forward.

The economic impact of Sandia National Laboratories on Central New Mexico and the State of New Mexico Fiscal Year 1998

Sandia National Laboratories (SNL) is a Department of Energy federally funded national security laboratory that uses engineering and science to ensure the security of the Nation. SNL provides scientific and engineering solutions to meet national needs in nuclear weapons and related defense systems, energy security, and environmental integrity. SNL works in partnerships with universities and industry to enhance their mission and transfer technology that will address emerging national challenges for both government and industry. For several years, the U.S. Department of Energy (DOE) Albuquerque Operations Office (AL) and New Mexico State University (NMSU) have maintained an inter-industry, input-output (I/O) model with capabilities to assess the impacts of developments initiated outside the economy such as federal DOE monies that flow into the state, on an economy. This model will be used to assess economic, personal income and employment impacts of SNL on Central New Mexico and the State of New Mexico. Caution should be exercised when comparing economic impacts between fiscal years prior to this report. The I/O model was rebased for FY 1998. The fringe benefits coefficients have been updated for the FY 1996 and FY 1997 economic impacts analysis. Prior to FY 1993 two different I/O base models were used to estimate the impacts. New technical information was released by the Bureau of Economic Analysis (BEA), U.S. Department of Commerce in 1991 and in 1994 and was incorporated in FY 1991, FY 1993, and FY 1994 I/O models. Also in 1993, the state and local tax coefficients and expenditure patterns were updated from a 1986 study for the FY 1992 report. Further details about the input-output model can be found in ''The Economic Impact of the Department of Energy on the State of New Mexico--FY 1998'' report by Lansford, et al. (1999). For this report, the reference period is FY 1998 (October 1, 1997, through September 30, 1998) and includes two major

How Mexico can advance its petroleum technology without political risk

Baker, G.

1992-01-01

This paper reports that Mexico's National Science Council (NSC) has made a strong appeal to strengthen Mexico's efforts in science. The energy sector is given special treatment, and NSC urges the federal administration to take a sharper look at the medium and long term implications of its modernization plans. The council urges greater efforts at energy conservation and encourages Mexico's State Petroleum Institute (IMP) to develop the horizontal drilling techniques that Pemex currently obtains only from foreign contractors. Aside from the value of NSC's well-intended advice to the IMP, the council's vision of the energy challenge of Mexico - and of the specific role the petroleum sector within that challenge - is narrowly conceived

1996-12-31

The development and evaluation of emissions data for sources located along the Mexico/US border have accelerated over the past few years. This paper examines several new activities in emissions inventory development for the northern border of Mexico. Reviewed in this paper are the following recent developments that will lead to improved inventories for Mexico: development of inventory educational materials; creation of inventory manuals; estimation of emissions for unique sources; emissions-related studies; and identification of key research needs for Mexico inventories. Some of these activities are building a greater capacity in Mexico to construct emissions estimates. These topics are reviewed from the perspective of improving Mexico emissions inventories and emissions estimation capabilities.

Physical Exposure to Seismic Hazards of Health Facilities in Mexico City, Mexico

Science.gov (United States)

Rodriguez, S. M.; Novelo Casanova, D.

2010-12-01

Although health facilities are essential infrastructure during disasters and emergencies, they are also usually highly vulnerable installations in the case of the occurrence of large and major earthquakes. Hospitals are one of the most complex critical facilities in modern cities and they are used as first response in emergency situations. The operability of a hospital must be maintained after the occurrence of a local strong earthquake in order to satisfy the need for medical care of the affected population. If a health facility is seriously damaged, it cannot fulfill its function when most is needed. In this case, hospitals become a casualty of the disaster. To identify the level of physical exposure of hospitals to seismic hazards in Mexico City, we analyzed their geographic location with respect to the seismic response of the different type of soils of the city from past earthquakes, mainly from the events that occurred on September 1985 (Ms= 8.0) and April 1989 (Ms= 6.9). Seismic wave amplification in this city is the result of the interaction of the incoming seismic waves with the soft and water saturated clay soils, on which a large part of Mexico City is built. The clay soils are remnants of the lake that existed in the Valley of Mexico and which has been drained gradually to accommodate the growing urban sprawl. Hospital facilities were converted from a simple database of names and locations into a map layer of resources. This resource layer was combined with other map layers showing areas of seismic microzonation in Mexico City. This overlay was then used to identify those hospitals that may be threatened by the occurrence of a large or major seismic event. We analyzed the public and private hospitals considered as main health facilities. Our results indicate that more than 50% of the hospitals are highly exposed to seismic hazards. Besides, in most of these health facilities we identified the lack of preventive measures and preparedness to reduce their

It was not until the last third of the 19th century, the period in which, according to historiography, the country definitely inserted itself into modernity, that anomalies and monstrosities had a presence in Mexico. Therefore, what I present here are four moments of teratology in Mexico, four dates in which I try to recount how teratology, which still occupied a marginal place within the main themes of national science, not only reached to cover the realm of medical discussions at the time, but also laid the foundations for new disciplines like biology and anthropology.

Background Mexico is one of the six countries formerly endemic for onchocerciasis in Latin America. Transmission has been interrupted in the three endemic foci of that country and mass drug distribution has ceased. Three years after mass drug distribution ended, post-treatment surveillance (PTS) surveys were undertaken which employed entomological indicators to check for transmission recrudescence. Methodology/Principal findings In-depth entomologic assessments were performed in 18 communities in the three endemic foci of Mexico. None of the 108,212 Simulium ochraceum s.l. collected from the three foci were found to contain parasite DNA when tested by polymerase chain reaction-enzyme-linked immunosorbent assay (PCR-ELISA), resulting in a maximum upper bound of the 95% confidence interval (95%-ULCI) of the infective rate in the vectors of 0.035/2,000 flies examined. This is an order of magnitude below the threshold of a 95%-ULCI of less than one infective fly per 2,000 flies tested, the current entomological criterion for interruption of transmission developed by the international community. The point estimate of seasonal transmission potential (STP) was zero, and the upper bound of the 95% confidence interval for the STP ranged from 1.2 to 1.7 L3/person/season in the different foci. This value is below all previous estimates for the minimum transmission potential required to maintain the parasite population. Conclusions/Significance The results from the in-depth entomological post treatment surveillance surveys strongly suggest that transmission has not resumed in the three foci of Mexico during the three years since the last distribution of ivermectin occurred; it was concluded that transmission remains undetectable without intervention, and Onchocerca volvulus has been eliminated from Mexico.

Research indicates that in-school adolescents in Mexico have their first sexual contact at the average age of 15.5 years. In 50% of cases, such contact is with a boyfriend or girlfriend, 28.1% with a fiance, and 18.3% with a prostitute. First sexual intercourse occurs with a spouse in only 1.3% of cases. Since only one in six young people in Mexico use a form of contraception, many unwanted pregnancies outside of marriage result. 450,000 births in 1989 were to mothers below 20 years old, with 15% of births annually being among teenage mothers. An estimated three million abortions occur annually in Mexico, and abortions are the fifth major cause of death at the national level. Teen pregnancy is decisively linked with poor living conditions and life expectancy, a relatively lower level of education, and rural residence. As for psychological and anthropological variables, most teens who become pregnant belong to large, unstable families with poor family communication, and are characterized as submissive, highly dependent, and of low self-esteem. Targeting students, workers, and other youths, the MEXFAM Youth Program selects and trains program coordinators over age 21 and volunteer promoters of both sexes aged 16-20 in urban/marginal communities. Promoters offer information to their peers and other youths in their local communities, distribute barrier contraceptives, and channel medical, psychological, and legal services to young people in need. Program procedure is described.

Differences and similarities in cancer patterns between the country of Mexico and the United States' Mexican population, 11% of the entire US population, have not been studied. Mortality data from 2008 to 2012 in Mexico and California were analyzed and compared for causes of cancer death among adult and pediatric populations, using standard techniques and negative binomial regression. A total of 380,227 cancer deaths from Mexico and California were included. Mexican Americans had 49% and 13% higher mortality than their counterparts in Mexico among males and females, respectively. For Mexican Immigrants in the US, overall cancer mortality was similar to Mexico, their country of birth, but all-cancers-combined rates mask wide variation by specific cancer site. The most extreme results were recorded when comparing Mexican Americans to Mexicans in Mexico: with mortality rate ratios ranging from 2.72 (95% CI: 2.44-3.03) for colorectal cancer in males to 0.28 (95% CI: 0.24-0.33) for cervical cancer in females. These findings further reinforce the preeminent role that the environment, in its multiple aspects, has on cancer. Overall, mortality from obesity and tobacco-related cancers was higher among Mexican origin populations in the US compared to Mexico, suggesting a higher risk for these cancers, while mortality from prostate, stomach, and especially cervical and pediatric cancers was markedly higher in Mexico. Among children, brain cancer and neuroblastoma patterns suggest an environmental role in the etiology of these malignancies as well. Partnered research between the US and Mexico for cancer studies is warranted. © 2017 UICC.

ALARA development in Mexico

Energy Technology Data Exchange (ETDEWEB)

Lopez, M.A.M. [Instituto Nacional de Investigaciones Nucleares, Col Lomas de Barrilaco (Mexico)

1995-03-01

Even though the ALARA philosophy was formally implemented in the early 1980`s, to some extent, ALARA considerations already had been incorporated into the design of most commercial equipment and facilities based on experience and engineering development. In Mexico, the design of medical and industrial facilities were based on international recommendations containing those considerations. With the construction of Laguna Verde Nuclear Power Station, formal ALARA groups were created to review some parts of its design, and to prepare the ALARA Program and related procedures necessary for its commercial operation. This paper begins with a brief historical description of ALARA development in Mexico, and then goes on to discuss our regulatory frame in Radiation Protection, some aspects of the ALARA Program, efforts in controlling and reducing of sources of radiation, and finally, future perspectives in the ALARA field.

Hepatitis E virus (HEV) infection is one of the most common causes of acute liver diseases in humans worldwide. In developing countries, HEV is commonly associated with waterborne outbreaks. Conversely, in industrialized countries, HEV infection is often associated with travel to endemic regions or ingestion of contaminated animal products. Limited information on both, human and animal HEV infection in Mexico is available. As a consequence, the distribution of the virus in the country is largely unknown. Here, we assessed the seroprevalence of HEV among swine in different geographical regions in Mexico. Seroprevalence of anti-HEV antibodies in swine herds in Mexico was evaluated in a representative sample including 945 pig serum specimens from different regions of the country using a commercial enzyme-linked immunosorbent assay (ELISA). The overall prevalence of anti-HEV antibodies in swine was 59.4%. The northern region of Mexico exhibited the highest seroprevalence in the country (86.6%), while the central and southern regions in Mexico showed lower seroprevalence, 42.7% and 51.5%, respectively. In Mexico, HEV seroprevalence in swine is high. Importantly, northern Mexico showed the highest seroprevalence in the country. Thus, further studies are required to identify the risk factors contributing to HEV transmission among pigs in the country. Assessment of HEV human infection in the context of viral transmission in swine is required to better understand the epidemiology of hepatitis E in Mexico.

Manufacturing real wages in Mexico

Directory of Open Access Journals (Sweden)

López V Antonia

2006-01-01

Full Text Available In this paper we analyse the recent evolution and determinants of real wages in Mexico?s manufacturing sector, using theories based on the assumption of imperfect competition both in the product and in the labour markets, especially wage-bargain theory, insider-outsider and mark-up models. We show evidence that the Mexican labour market does not behave as a traditional competitive market. The proposed explanation for this fact is that some workers benefit from advantages when compared with others, so that they can get a greater share of the proceedings of the productive process. Also, we find that changes in the degree of competition in the market for output influence the behaviour of real wages.

In 1950 Mexico entered an economic takeoff and grew rapidly for more than 30 years. Growth stopped during the crises of 1982-1995, despite major reforms, including liberalization of foreign trade and investment. Since then growth has been modest. We analyze the economic history of Mexico 1877-2010. We conclude that the growth 1950-1981 was driven by urbanization, industrialization, and education and that Mexico would have grown even more rapidly if trade and investment had been liberalized so...

Manufacturing poverty: the maquiladorization of Mexico.

Science.gov (United States)

La Botz, D

1994-01-01

Based on interviews with social workers, attorneys, feminists, union activists, and factory workers, the author argues that the maquiladora free trade zone of Northern Mexico portends developments under the North American Free Trade Agreement. Today some 500,000 Mexican workers labor in 2,000 factories for $4.50 a day in Mexico's maquiladoras. Two-thirds of the workers are women, many single women who head their households. These women work in the new, modern manufacturing plants in industrial parks, but live in squalid shantytowns without adequate water, sewage, or electricity. On the job, workers face exposures to toxic chemicals and dangerous work processes. The Mexican government does not have the political will, the trained personnel, or the equipment to monitor these occupational health problems. While Mexico's Constitution and labor laws guarantee workers the right to organize, bargain collectively, and strike, in practice the state controls the unions and opposes worker activism. In the face of employer and state repression workers are forced to organize secretly to fight for higher wages and safer conditions.

1999-01-01

Sandia National Laboratories (SNL) is a Department of Energy federally funded national security laboratory that uses engineering and science to ensure the security of the Nation. SNL provides scientific and engineering solutions to meet national needs in nuclear weapons and related defense systems, energy security, and environmental integrity. SNL works in partnerships with universities and industry to enhance their mission and transfer technology that will address emerging national challenges for both government and industry. For several years, the U.S. Department of Energy (DOE) Albuquerque Operations Office (AL) and New Mexico State University (NMSU) have maintained an inter-industry, input-output (I/O) model with capabilities to assess the impacts of developments initiated outside the economy such as federal DOE monies that flow into the state, on an economy. This model will be used to assess economic, personal income and employment impacts of SNL on Central New Mexico and the State of New Mexico. Caution should be exercised when comparing economic impacts between fiscal years prior to this report. The I/O model was rebased for FY 1998. The fringe benefits coefficients have been updated for the FY 1996 and FY 1997 economic impacts analysis. Prior to FY 1993 two different I/O base models were used to estimate the impacts. New technical information was released by the Bureau of Economic Analysis (BEA), U.S. Department of Commerce in 1991 and in 1994 and was incorporated in FY 1991, FY 1993, and FY 1994 I/O models. Also in 1993, the state and local tax coefficients and expenditure patterns were updated from a 1986 study for the FY 1992 report. Further details about the input-output model can be found in ''The Economic Impact of the Department of Energy on the State of New Mexico-FY 1998'' report by Lansford, et al. (1999). For this report, the reference period is FY 1998 (October 1, 1997, through September 30, 1998) and includes two major impact analyses: The

2005-02-01

The goal of this study was to provide further information about helminth parasites of Virginia opossum Didelphis virginiana Kerr, 1792 from Mexico. During routine faunal investigations between 1958 and 2001, 101 opossum were necropsied. Nineteen taxa of helminths were collected, representing 13 genera from hosts in 27 localities from Mexico. There are 58 new locality records, with 6 species recorded in Mexico for the first time: Brachylaima virginiana Dickerson, 1930; Cruzia americana Mapleston, 1930; Didelphonema longispiculata (Hill, 1939); Didelphostrongylus hayesi Prestwood, 1976; Viannaia didelphis Travassos, 1914; and Viannaia viannai Travassos, 1914. This increases the number of helminth taxa previously known for this host in Mexico to 28.

The alternative fuels are born with the goal of not damaging the environment; biodiesel, electricity, ethanol, hydrogen, methanol, natural gas, LP gas, are the main alternative fuels. However, the biodiesel and bioetanol are the only completely renewable ones, this makes them ideal to be developed in Mexico, since the agricultural sector could be fortified, the technological independence be favored, improve the conservation of the oil resources and by all means not to affect the environment. On the other hand, also efficient cultivation techniques should be developed to guarantee the economy of the process. [Spanish] Los combustibles alternativos nacen con la meta de no danar el medio ambiente; el biodiesel, electricidad, etanol, hidrogeno, metanol, gas natural, gas LP, son los principales combustibles alternativos.

New Mexico low-temperature geothermal resources and economic development programs

International Nuclear Information System (INIS)

Whittier, J.; Schoenmackers, R.

1990-01-01

This paper reports on New Mexico's low-temperature geothermal resources which have been utilized to promote economic development initiatives within the state. Public funds have been leveraged to foster exploration activities which have led to the establishment of several direct-use projects at various sites within New Mexico. State policies have focused on attracting one business sector, the commercial greenhouse industry, to expand and/or relocate in New Mexico. Geothermal-related promotional activities have begun to show success in achieving economic growth. New Mexico now has almost half of the geothermally-heated greenhouse space in the nation. It is anticipated that the greenhouse sector will continue to grow within the state. Future economic development activities, also relying upon the geothermal resource base, will include vegetable dehydration and aquaculture with a focus on the microalgae sector

Genetic relatedness among Solanum L. species assayed by seed morphology and isozyme markers

2016-01-01

In spite of their economic and medicinal value, no adequate attention has been paid to the diversity, characterization and taxonomical identification of Solanum L. species in Saudi Arabia. In this study, Scanning Electron Microscopy (SEM) of seed coat morphology and isozyme electrophoresis were employed for studying the genetic variability and relationships among seven Solanum L. species namely; S. incanum L., S. nigrum L., S. villosum L., S. schemprianum Hochst, S. galabratum Dunal, S. lycopersicum L. and S. melongena L. collected from Taif highlands. Scanning Electron Microscope (SEM) investigation of seed coat sculpturing showed three basic patterns namely; rugulate, reticulate and levigate. The analyses on six enzymes were coded by 19 loci. The number of alleles ranged from one to three with a mean of 1.58 alleles per locus. The proportion of polymorphic loci for Solanum L. species ranged from 0.87 for S. nigrum L. and S. villosum L. to 0.80 for S. lycopersicum L. The mean observed heterozygosity varied from 0.00 to 1.00, while mean expected heterozygosity ranged between 0.00 and 0.5. The UPGMA phenogram confirmed the extensive genetic diversity existed in the studied Solanum L. species and showed the close relationship between S. incanum L. and S. melongena L. (author)

Faulting in eastern New Mexico: Revision 1

International Nuclear Information System (INIS)

Murphy, P.J.

1987-08-01

This area in eastern New Mexico is being studied because of its proximity to a proposed high-level nuclear waste repository site in Deaf Smith County, Texas. Regional and local tectonics must be thoroughly understood in order to be able to predict future tectonic activities in the site region. Hydrogeologic studies indicate that ground-water recharge, for regional deep and shallow aquifer systems, occurs primarily within the study area. Regional, easterly ground-water flow may be significantly affected by the spacing, orientation, and character of faults identified in this report. The tectonic history of eastern New Mexico is developed from information from 660 exploratory wells. A history of recurrent tectonic movements is evident, beginning possibly in the late Precambrian and extending into the late Cenozoic. The nature of the evidence includes the lateral and vertical distribution and the lithology of these deposits. The results are presented mainly as isopach and structure contour maps and as structural cross sections. The Paleozoic tectonic history of eastern New Mexico is similar and related to the history of the Texas Panhandle. Differences occur primarily in the Mesozoic and Cenozoic histories; tectonic uplift persisted for longer periods and faults show evidence of repeated movements in eastern New Mexico. This is probably a result of the proximity of the area to the Laramide and Basin and Range deformational events. 442 refs., 35 figs

Abortion legalization and childbearing in Mexico1

Science.gov (United States)

Gutierrez Vazquez, Edith Y.; Parrado, Emilio A.

2016-01-01

In 2007 abortion was legalized in the Federal District of Mexico, making the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. In this paper, we examine metropolitan area differences in overall and parity-specific, as well as the age pattern of childbearing between 2000 and 2010 to more precisely isolate the contribution of abortion legalization to fertility in Mexico. Our statistical specification applies difference-in-difference regression methods that control for concomitant changes in other socioeconomic predictors of fertility to assess the differential influence of the law across age groups. In addition, we account for prior fertility levels and change to better separate the effect of the law from preceding trends. Overall, the evidence suggests a systematic association between abortion legalization and fertility. The law appears to have contributed to lower fertility in Mexico City compared to other metropolitan areas and prior trends, though the influence is mostly visible among women aged 20-34 in connection with the transition to first and second child with limited impact on teenage fertility. There is some evidence that its effect might be diffusing to the greater Mexico City metropolitan area. PMID:27285423

A survey of 222Rn in drinking water in mexico city

International Nuclear Information System (INIS)

Vasquez-Lopez, C.; Zendejas-Leal, B. E.; Golzarri, J. I.; Espinosa, G.

2011-01-01

In Mexico City there are more than 22 millions of inhabitants (10 in the metropolitan area and 12 in the suburban zone) exposed to drinking water. The local epidemiological authorities recognised that exposure to radon contaminated drinking water is a potential health hazard, as has been considered worldwide. The United States Environmental Protection Agency has proposed a limit of 11.1 Bq l -1 for the radon level in drinking water. In Mexico a maximum contamination level of radon in drinking water has not yet even considered. In this work, a 222 Rn study of drinking water in Mexico City has revealed a range of concentrations from background level to 3.8 Bq l -1 . 222 Rn was calculated using a portable degassing system (AquaKIT) associated with an AlphaGUARD measuring system. Samples from 70 wells of the water system of the south of the Valley Basin of Mexico City and from houses of some other political administrative divisions of Mexico City were taken. (authors)

Los Alamos National Laboratory (LANL) is a multidisciplinary, multiprogram laboratory with a mission to enhance national military and economic security through science and technology. Its mission is to reduce the nuclear danger through stewardship of the nation's nuclear stockpile and through its nonproliferation and verification activities. An important secondary mission is to promote US industrial competitiveness by working with US companies in technology transfer and technology development partnerships. Los Alamos is involved in partnerships and collaborations with other federal agencies, with industry (including New Mexico businesses), and with universities worldwide. For this report, the reference period is FY 1997 (October 1, 1996, through September 30, 1997) and includes two major impact analysis: the impact of LANL activities on north-central New Mexico and the economic impacts of LANL on the state of New Mexico. Total impact represents both direct and indirect respending by business, including induced effects (respending by households). The standard multipliers used in determining impacts result from the inter-industry, input-output models developed for the three-county region and the state of New Mexico. 5 figs., 12 tabs

Aging in Mexico: Population Trends and Emerging Issues

Science.gov (United States)

Vega, William; López-Ortega, Mariana

2017-01-01

Abstract Although all nations in the America’s face a common demographic reality of longevity, declining fertility rates and changes in family roles a growing body of research points to a dramatic demographic transformation in Mexico. Although Mexico’s population is relatively young, with a median age of 27.9 in 2015, it will age rapidly in coming years, increasing to 42 years by 2050. The rapid median age in the nation also reflects the growing proportion of people 65 or older, and is expected to triple to 20.2% by 2050. This article examines how the age and gender structure of Mexico offers important insights about current and future political and social stability, as well as economic development. Mexico is the world’s eleventh largest country in terms of population size and the “demographic dividend” of a large youthful population is giving way to a growing older population that will inevitably place demands on health care and social security. The shift in age structure will result in increased dependency of retirees on the working-age population in the next 20 years. Mexico does not provide universal coverage of social security benefits and less than half of the labor force is covered by any pension or retirement plan. As a result, elderly Mexicans often continue working into old age. The high total poverty rate in the country, especially among the older population magnifies the problem of the potential dependency burden. The article ends with a discussion of key public policy issues related to aging in Mexico. PMID:27927730

Recent studies in Mexico have documented a significant increase in crack cocaine use, indicating the potential for an emerging drug epidemic. Ethnographic observations and interviews were used describe the profiles and patterns of use among street-recruited crack users in Mexico City. The data came from an international research collaboration funded by the National Institutes of Health. A polythetic typology was developed based on five dimensions central to categorizing patterns of crack use behavior: frequency of use, duration of use, context, social networks, and social contracts. Four types of users were discovered applying these dimensions: dabblers, stable users, crack heads, and old heads. Although several similarities were documented between patterns of crack use in Mexico and those in the United States and Western Europe, several key aspects distinguished crack users in this population: (1) self-regulated use; (2) non-linear progression of crack; and (3) the influence of the dimensions pertaining to setting, social networks, and social contract as contributing to understanding of the previous two. Further, we provide a discussion of how specific contextual factors in Mexico may be giving rise to these emerging patterns. Compared to the U.S. and Europe, this study finds that the majority of crack users were able to self-regulate their use without major disruption to daily social functioning. As crack use spreads in Mexico and other Latin American countries, we need to recognize the importance of social context in developing more tailored health and social responses that are specific to these developing countries.

Peterson, R.H.; Cooke, D.W.

1995-01-01

The geologic setting in the deep-water (depths greater than 1,500 feet) Gulf of Mexico is very favorable for the existence of large, commercial hydrocarbon accumulations. These areas have active salt tectonics that create abundant traps, underlying mature Mesozoic source rocks that can be observed expelling oil and gas to the ocean surface, and good quality reservoirs provided by turbidite sand deposits. Despite the limited amount of drilling in the deep-water Gulf of Mexico, 11 deep-water accumulations have been discovered which, when developed, will rank in the top 100 largest fields in the Gulf of Mexico. Proved field discoveries (those with announced development plans) have added over 1 billion barrels of oil equivalent to Gulf of Mexico reserves, and unproved field discoveries may add to additional billion barrels of oil equivalent. The Minerals Management Service, United States Department of the Interior, has completed a gulf-wide review of over 1,086 oil and gas fields and placed every pay sand in each field into a hydrocarbon play (plays are defined by chronostratigraphy, lithostratigraph, structure, and production). Seven productive hydrocarbon plays were identified in the deep-water northern Gulf of Mexico. Regional maps illustrate the productive limits of each play. In addition, field data, dry holes, and wells with sub-economic pay were added to define the facies and structural limits for each play. Areas for exploration potential are identified for each hydrocarbon play. A type field for each play is chosen to demonstrate the play's characteristics

Oil's role in free trade agreement crux of Mexico's petroleum sector dilemma

International Nuclear Information System (INIS)

Anon.

1992-01-01

Mexico's president Salinas' efforts at privatization have not yet touched Mexico's most valuable industry, oil. That remains under control of state owned Petroleos Mexicanos. Pemex and Mexico's huge oil union have come under increasing criticism for alleged abuses of power. In addition, controversy rages as to the true extent of Mexican oil resources and whether Pemex has the wherewithal to meet domestic demand and sustain oil exports. Critics also contend opening Mexico's oil sector to foreign participation would introduce new efficiencies and cost cutting measures in the cash strapped state oil industry. This paper reports that at the center of the controversy is the proposed Free Trade Agreement among Mexico, the U.S., and Canada, pushed strongly by Salinas. Oil's role in the FTA may prove the pact's main sticking point

To determine the glaucoma specialists' preferences for the different brands of topical glaucoma medications available in Mexico. A web-based survey was sent to 150 board-certified glaucoma specialists in Mexico, with 14 questions related to brand preferences for all glaucoma medications available in Mexico. Participants were asked to select each glaucoma medication class by brand and to state the factors leading to their choice. Data from 111 (74%) glaucoma specialists were collected. Imot (timolol 0.5%; Sophia, Mexico) was the preferred brand for the beta-blockers (BB) class by 71% (n = 79) of the participants. Azopt (brinzolamide 1%; Alcon Lab, US) was the preferred carbonic anhydrase inhibitor (CAI) by 54% (n = 60) of the glaucoma specialists. Lumigan (bimatoprost 0.01% and 0.03%; Allergan Inc., U.S.) was the first choice for the prostaglandin analogues (PGAs) in 62% (n = 70) of the answers. The most frequently prescribed alpha-agonist (AA) was Agglad (brimonidine 0.2%; Sophia Lab, Mexico) in 44% (n = 49) of the answers. Medication accessibility (31%), cost (29%), and recommended dose (23%) were the three main factors influencing the glaucoma specialists' preferences. Medication cost and accessibility, as well as posology, remain the main factors influencing brand preferences among glaucoma doctors. In our professional opinion, the therapeutic effect must be the leading factor when prescribing topical medications in the daily practice, so that patients receive the best treatment option. This survey provides an understanding of the decision-making process when prescribing glaucoma medications by glaucoma specialists in a Latin American developing country. Ideally, patient treatment should be individualized and aimed to achieve the best results possible for their specific condition.

Mexico: a regional power or a failed State?

Directory of Open Access Journals (Sweden)

Karol Derwich

2015-10-01

Caribbean region for many years. This opinion has strong foundations. Territory, geographical location, economy, and political influence are the key factors that predestine this country to the role of a regional power. The democratic transition that has taken place in Mexico in last decades and economic cooperation with the United States also allow it to play a role of regional leader. However, Mexico has significant problems that make it difficult for the country to play the role of a real leader. The most important one is the development of narcobusiness. This phenomenon brings not only the growing activity of drug cartels but also the eruption of narcoviolence in Mexico. This gives rise to grave problems for the Mexican authorities. The development of narcobusiness is partially the result of weakness of some of its institutions. For example, police forces do not carry out their tasks and are closely related to the drug cartels. As a result, the Mexican state is incapable of assuring security to its citizens – one of the most important functions of every state. Is it able to control its territory? It definitely does not have a monopoly for the use of violence on its territory. Huge corruption enables different non-state actors to influence decision making processes. All these problems make substantiated theses that the Mexican state is dysfunctional in some areas. Some analysts go much further in their opinions and describe Mexico as a failed state. The aim of the paper is to analyze the present position of Mexico in Latin America and the Caribbean region. Are the contemporary problems so big that they can lead to the collapse of the Mexican state or does Mexico have a real potential to play the role of a local leader and regional power? The author would like to analyze the impact of the present day internal problems in Mexico’s geopolitical position.

Mexico and Asia-Pacific: proximities and distances of a long relationship

2015-09-01

Full Text Available Mexico and Asia-Pacific have strong links and yet they keep their distance at a subjective level. This article analyses this complex relationship in order to identify the points of approchement and bilateral distancing from a historical perspective. The text analyses the economic, trade, political and multilateral links between Mexico and the main countries and regional organisations in the region of Asia-Pacific. It observes that, despite the economic emergence of Asia-Pacific in recent decades, Mexico alternates between periods of distancing and rapprochement. If it maintains this trend, Mexico will lose out on participating actively in the region where the most dynamic international relations in the 21st century are being formed.

Estrada, J.

1997-01-01

Terms of the policy and regulatory reform for the natural gas sector in Mexico since 1993 were described, and major changes taking place in the structure, organization and operations of the sector since the introduction of reforms were reviewed. Consequences that the structural changes are likely to have on the long-term balance of natural gas supply and demand in Mexico, have been assessed. The goal of full open access by November of 1997 was reiterated. Reforms to the electric power industry also have been undertaken. As with natural gas, the objective is to eliminate the State monopoly and to allow private power producers to participate in the expansion of the sector's generating capacity. Public investment will be directed towards the improvement of transmission and distribution networks. Over time, independent power producers are expected to become the principal source of funds for the expansion of electric power availability in Mexico. 3 tabs., 29 figs

Human rights and conventionality control in Mexico

Directory of Open Access Journals (Sweden)

Azul América Aguiar-Aguilar

2014-12-01

Full Text Available The protection of human rights in Mexico has, de jure, suffered an important change in the last years, given a new judicial interpretation delivered by the National Supreme Court of Justice that allows the use of conventionality control, which means, that it allows federal and state judges to verify the conformity of domestic laws with those established in the Inter-American Convention of Human Rights. To what extent domestic actors are protecting human rights using this new legal tool called conventionality control? In this article I explore whom and how is conventionality control being used in Mexico. Using N-Vivo Software I reviewed concluded decisions delivered by intermediate level courts (Collegiate Circuit Courts in three Mexican states. The evidence points that conventionality control is a very useful tool especially to defenders, who appear in sentences claiming compliance with the commitments Mexico has acquired when this country ratified the Convention.

Radon in soil concentration levels in Mexico

Segovia, N.; Tamez, E.; Mena, M.

1991-09-01

Radon in soil surveys in Mexico have been carried out since 1974 both for uranium prospectus and to correlate mean values of the gas emanation with local telluric behaviour. The mapping includes the northern uranium mining region, the Mexican Neo volcanic Belt, the coastal areas adjacent to the zone of subduction of the Cocos Plate under the North American Plate, some of the active volcanoes of Southern Mexico and several sedimentary valleys in Central Mexico. Recording of 222 Rn alpha decay is systematically performed with LR115 track detectors. Using mean values averaged over different observation periods at fixed monitoring stations, a radon in soil map covering one third of the Mexican territory is presented. The lowest mean values have been found in areas associated with active volcanoes. The highest levels are found in uranium ore zones. Intermediate values are obtained in regions with enhanced hydrothermal activity and stations associated with intrusive rocks. (Author)

Modeling the distributions of species, especially of invasive species in non-native ranges, involves multiple challenges. Here, we developed some novel approaches to species distribution modeling aimed at reducing the influences of such challenges and improving the realism of projections. We estimated species-environment relationships for Parthenium hysterophorus L. (Asteraceae) with four modeling methods run with multiple scenarios of (i) sources of occurrences and geographically isolated background ranges for absences, (ii) approaches to drawing background (absence) points, and (iii) alternate sets of predictor variables. We further tested various quantitative metrics of model evaluation against biological insight. Model projections were very sensitive to the choice of training dataset. Model accuracy was much improved using a global dataset for model training, rather than restricting data input to the species' native range. AUC score was a poor metric for model evaluation and, if used alone, was not a useful criterion for assessing model performance. Projections away from the sampled space (i.e., into areas of potential future invasion) were very different depending on the modeling methods used, raising questions about the reliability of ensemble projections. Generalized linear models gave very unrealistic projections far away from the training region. Models that efficiently fit the dominant pattern, but exclude highly local patterns in the dataset and capture interactions as they appear in data (e.g., boosted regression trees), improved generalization of the models. Biological knowledge of the species and its distribution was important in refining choices about the best set of projections. A post hoc test conducted on a new Parthenium dataset from Nepal validated excellent predictive performance of our 'best' model. We showed that vast stretches of currently uninvaded geographic areas on multiple continents harbor highly suitable habitats for parthenium

Public Acceptance of Nuclear Energy in Mexico

International Nuclear Information System (INIS)

Ramirez-Sanchez, Jose R.; Alonso, Gustavo; Palacios, H. Javier

2006-01-01

The nuclear energy is attracting renewed interest of public and policy makers due to his potential role in long term strategies aiming to reduce the risk of global warming and in a more general, to carry out sustainable policies, however, any project of nuclear nature arise concerns about the risks associated with the release of radioactivity during accident conditions, radioactive waste disposal and nuclear weapons proliferation. Then in light of the likeliness for a new nuclear project in Mexico, is necessary to design a strategy to improve the social acceptance of nuclear power. This concern is been boarding since the environmental and economic point of view. The information that can change the perception of nuclear energy towards increase public acceptance, should be an honest debate about the benefits of nuclear energy, of course there are questions and they have to be answered, but in a realistic and scientific way: So thinking in Mexico as a first step it is important to communicate to the government entities and political parties that nuclear energy is a proven asset that it is emission free and safe. Of course besides the guarantee of a proven technology, clean and safe relies the economic fact, and in Mexico this could be the most important aspect to communicate to key people in government. Based in the Laguna Verde survey it is clear that we have to find the adequate means to distribute the real information concerning nuclear technology to the public, because the results shows that Mexican people does not have complete information about nuclear energy, but public can support it when they have enough information. From the IAEA study we can say that in Mexico public acceptance of nuclear energy it s not so bad, is the highest percentage of acceptance of nuclear technology for health, considering benefits to the environment Mexican opposition to build new plants is the second less percentage, and generally speaking 60% of the people accept somehow nuclear

The stable carbon isotope composition of sedimentary organic carbon was determined in the sediments of seven coastal lagoons of the Gulf of Mexico, Mexico. For most of the lagoons the delta 13 C values for sediments ranged from -20.1 to -23.9 parts per thousand. Anomalously low values, -26.8 to 29.3 parts per thousand were determined in sediments of two of the studied lagoons, probably due to the presence of organic carbon from anthropogenic sources, naturally absent in these environments. The delta 13 C values determined in the tissues of oysters collected at the same time in the different lagoons were very similar to those recorded in the sediments. (author)

On the Loop Current Penetration into the Gulf of Mexico

Science.gov (United States)

Weisberg, Robert H.; Liu, Yonggang

2017-12-01

The Gulf of Mexico Loop Current generally intrudes some distance into the Gulf of Mexico before shedding an anticyclonic eddy and retreating back to its more direct entry to exit pathway. The control of this aperiodic process remains only partially known. Here we describe the evolution of the Loop Current throughout the era of satellite altimetry, and offer a mechanistic hypothesis on Loop Current intrusion. As a complement to the known effects of Loop Current forcing on the west Florida shelf circulation, we argue that the west Florida shelf, in turn, impacts the Loop Current evolution. A Self-Organizing Map analysis shows that anomalous northward penetrations of the Loop Current into the Gulf of Mexico occur when the eastern side of Loop Current is positioned west from the southwest corner of the west Florida shelf, whereas the more direct inflow to outflow route occurs when the eastern side of the Loop Current comes in contact with the southwest corner of the west Florida shelf. In essence, we argue that the west Florida shelf anchors the Loop Current in its direct path configuration and that farther northward penetration into the Gulf of Mexico occurs when such anchoring is released. To test of this hypothesis heuristically, we estimate that the dissipation and buoyancy work due to known Loop Current forcing of the west Florida shelf circulation (when in contact with the southwest corner) may exceed the pressure work required for the Loop Current to advance against the ambient Gulf of Mexico fluid.Plain Language SummaryThe Gulf of Mexico Loop Current may intrude far into the Gulf of Mexico or take a more direct entry to exit pathway. Such Loop Current behaviors are described using remote observations by satellites, and a heuristic hypothesis on the control of Loop Current intrusion is presented. We argue that energy dissipation and buoyancy work by the west Florida shelf circulation, when the Loop Current contacts the southwest corner of the west Florida shelf

Mexico solar market: shortterm pain brings long-term gains

International Nuclear Information System (INIS)

Lacey, S.

2016-01-01

Mexico is installed solar PV capacity is currently at less than 1 GW and in all probability, only 2 to 3 GW will be added by 2020. Until recently, Mexico represented the most promising solar market in Latin America. But the strong growth expected for the country is now much less certain. In fact, solar installation figures in 2016 could be 36% lower than those projected last year. So what has happened? As GTM Research has documented, solar project developers and financiers are dealing with a completely new set of rules for selling solar electricity into Mexico energy market. Those new rules are causing some confusion and, as such, activity has slowed down. (Author)

Environmental injustice along the US-Mexico border: residential proximity to industrial parks in Tijuana, Mexico

Science.gov (United States)

Grineski, Sara E.; Collins, Timothy W.; de Lourdes Romo Aguilar, María

2015-09-01

Research in the Global North (e.g., US, Europe) has revealed robust patterns of environmental injustice whereby low income and minority residents face exposure to industrial hazards in their neighborhoods. A small body of research suggests that patterns of environmental injustice may diverge between the Global North and South due to differing urban development trajectories. This study uses quantitative environmental justice methods to examine spatial relationships between residential socio-demographics and industrial parks in Tijuana, Baja California Norte, Mexico using 2010 census data for Tijuana’s 401 neighborhoods and municipality-provided locations of industrial parks in the city. Results of spatial lag regression models reveal that formal development is significantly associated with industrial park density, and it accounts for the significant effect of higher socioeconomic status (measured using mean education) on greater industrial density. Higher proportions of female-headed households are also significantly associated with industrial park density, while higher proportions of children and recent migrants are not. The formal development findings align with other studies in Mexico and point to the importance of urban development trajectories in shaping patterns of environmental injustice. The risks for female-headed households are novel in the Mexican context. One potential explanation is that women factory workers live near their places of employment. A second, albeit counterintuitive explanation, is the relative economic advantage experienced by female-headed households in Mexico.

Baker, Brian J.; Jeffries, Carla D.; Moonan, Patrick K.

2016-01-01

Background In 2010, Mexico was the most common (22.9%) country of origin for foreign-born persons with tuberculosis in the United States, and overall trends in tuberculosis morbidity are substantially influenced by the Mexico-born population. Objectives To determine the risk of tuberculosis disease among Mexico-born persons living in the United States. Methods Using data from the U.S. National Tuberculosis Surveillance System and the American Community Survey, we examined tuberculosis case counts and case rates stratified by years since entry into the United States and geographic proximity to the United States–Mexico border. We calculated trends in case rates over time measured by average annual percent change. Results The total tuberculosis case count (−14.5%) and annual tuberculosis case rate (average annual percent change −5.1%) declined among Mexico-born persons. Among those diagnosed with tuberculosis less than 1 year since entry into the United States (newly arrived persons), there was a decrease in tuberculosis cases (−60.4%), no change in tuberculosis case rate (average annual percent change of 0.0%), and a decrease in population (−60.7%). Among those living in the United States for more than 5 years (non-recently arrived persons), there was an increase in tuberculosis cases (+3.4%), a decrease in tuberculosis case rate (average annual percent change of −4.9%), and an increase in population (+62.7%). In 2010, 66.7% of Mexico-born cases were among non–recently arrived persons, compared with 51.1% in 2000. Although border states reported the highest proportions (>15%) of tuberculosis cases that were Mexico-born, the highest Mexico-born–specific tuberculosis case rates (>20/100,000 population) were in states in the eastern and southeastern regions of the United States. Conclusions The decline in tuberculosis morbidity among Mexico-born persons may be attributed to fewer newly arrived persons from Mexico and lower tuberculosis case rates among

Los Alamos National Laboratory (LANL) is a multidisciplinary, multiprogram laboratory with a mission to enhance national military and economic security through science and technology. Its mission is to reduce the nuclear danger through stewardship of the nation's nuclear stockpile and through its nonproliferation and verification activities. An important secondary mission is to promote US industrial competitiveness by working with US companies in technology transfer and technology development partnerships. Los Alamos is involved in partnerships and collaborations with other federal agencies, with industry (including New Mexico businesses), and with universities worldwide. For this report, the reference period is FY 1998 (October 1, 1997, through September 30, 1998). It includes two major impact analysis: the impact of LANL activities on north-central New Mexico and the economic impacts of LANL on the state of New Mexico. Total impact represents both direct and indirect responding by business, including induced effects (responding by households). The standard multipliers used in determining impacts result from the inter-industry, input-output models developed for the three-county region and the state of New Mexico

Population, petroleum, and politics: Mexico at the crossroads. Pt. 1.

Gallagher, C F

By 1975 Mexico's estimated population was 59.6 million, the median age, 16.2 years, lower than any major country. This growth has been accompanied by massive internal migrations and urbanization. By 1970 the previously pronatalist policy of the government began to shift to one more favorable to family planning. The proximity to the U.S. has made Mexico's history subject to neocolonialism. Until the 1938 nationalization of oil, few of Mexico's decisions were her own. Mexico began to prosper after World War 2, and from 1945-72 the annual growth rate averaged 6%. Mortality decreased while birth rates remained high. Changes in policy have led to dramatic decreases in the birth rate. In 1973 only 11% of all married women were using contraceptives; by 1976 21% were. The 1977-78 birth rate was about 37/1000. Mexico now has a master population plan calling for reduction of the rate of natural increase to 2.5% in 1982 and 1.8% in 1988. The budget or the National Family Planning Coordination was raised in 1979 from 450 million to 700 million pesos (about $32 million). The problem facing Mexico is how to provide employment and education for the more than 40 million people to be born in the next 2 decades. With the increase of women in the work force, 1,200.000 jobs will be needed by the beginning of the 1990s. New oil deposits and the wealth from them are being seen as the solution that will provide the development resources to overcome population problems.

Anthropoentomophagic biodiversity of the Zongolica region, Veracruz, Mexico. During two and a half years (2003-2005) we recorded the insect species used as food at Zongolica, Veracruz State, Mexico. Interviews were made among people (200) of this municipality to know which insects they consumed. The total of registered species was 57 (Orthoptera, Hemiptera, Homoptera, Megaloptera, Coleoptera, Lepidoptera and Hymenoptera). The Orthoptera was the most frequently ingested. Twenty-four of these species were new records for edible insects of Mexico. They are eaten in immature stages or as adults, generally only roasted. Consumption is seasonal. Some species are commercialized in the "tianguis" (little town markets) and/or in the larger Zongolica market. There is a "protoculture" of three species, one cockroach (Periplaneta australasiae Fabricius) and two moths (Latebraria amphipyroides Guenée and Arsenura armida armida Cramer). In Zongolica, anthropoentomophagy is an ancestral habit.

Organizing in a National Sacrifice Area: the radioactive waste campaign in New Mexico

International Nuclear Information System (INIS)

Colombo, L.J.

1981-01-01

Organizing in a National Sacrifice Area concerns a citizens' campaign to affect the development of a Federal radioactive waste disposal facility in New Mexico. This facility, called the Waste Isolation Pilot Plant (WIPP), is intended to be the first permanent radioactive waste disposal facility in the United States. The three principal elements of this work are: (1) demographic, economic and attitudinal information providing the social context for the citizens' campaign; (2) the theory and practice of community organizing with respect to the New Mexico radioactive waste disposal project; and (3) the history of citizen activities to affect the New Mexico state legislature on this issue. The demographic and attitudinal information include: survey research conducted previously concerning nuclear waste and nuclear power; demographic and economic data for New Mexico principally from the 1970 Census; a secondary analysis of a base-line survey concerning nuclear development in New Mexico; and original qualitative and survey research dealing with public attitudes in the state on the WIPP project. The attitude change and maintenance literature are also reviewed. This dissertation covers the events constituting the establishment of the WIPP project in New Mexico and citizen activities both opposed to and in support of the radioactive waste disposal project. In addition, citizen activity to influence the New Mexico state legislature in 1979 with regard to radioactive waste disposal is reviewed. An analysis of the New Mexico state legislature in terms of this issue is made also

Describe the resources for the treatment of breast cancer in Mexico. Information was obtained from 23 Centros Estatales de Cáncer (State Cancer Centers, CEC), two federal hospitals and Cancerología. This study was performed in Mexico City in August/September of 2008. These 23 centers provide medical care for breast cancer including surgery, chemotherapy and radiotherapy; all of them validated by the Seguro Popular. The costs were defined according to clinical stage and ranged from $27,500.00 pesos for clinical stage 0 to $480,00.00 in the advanced stage. A total of 2 689 women with breast cancer have been treated; only 1% was reported with in situ carcinoma. An adequate medical infrastructure is in place to treat breast cancer in Mexico. The costs are high due to late diagnosis of the disease. Early detection of breast cancer is a high priority for optimal control of this disease in Mexico.

Bioseguridad in Mexico: Pursuing Security between Local and Global Biologies.

Science.gov (United States)

Wanderer, Emily Mannix

2017-09-01

In the aftermath of the 2009 outbreak of H1N1 influenza, scientists in Mexico sought to develop bioseguridad, that is, to protect biological life in Mexico by safely conducting research on infectious disease. Drawing on ethnographic research in laboratories and with scientists in Mexico, I look at how scientists make claims about local differences in regulations, infrastructure, bodies, and culture. The scientists working with infectious microbes sought to establish how different microbial ecologies, human immune systems, and political and regulatory systems made the risks of research different in Mexico from other countries. In developing bioseguridad, the idea of globalized biology that animates many public health projects was undermined as scientists attended to the elements of place that affected human health and safety. Scientists argued for the importance of local biologies, generating tension with global public health projects and regulations premised on the universality of biology. © 2016 by the American Anthropological Association.

International Uranium Resources Evaluation Project (IUREP) national favourability studies: Mexico

International Nuclear Information System (INIS)

1977-07-01

Reserves of uranium are located in the north eastern part of Mexico, primarily in the states of Tamaulipas and Chihuahua. Most of the remainder of Mexico's reserves are near the Tamaulipas-Neuvo Leon state border in the Tertiary Frio Formation, where they apparently occur in the types of uranium deposits found in Texas, U.S.A. There are two deposits, La Coma and Buenavista, but nothing has been published on dimensions of the ore bodies. Forty-five miles northeast of Hermosillo, in Sonora state is the Los Amoles district where uranium is found associated with gold and other metals in low-grade deposits on the margins of a Cretaceous batholith. Another occurrence is reported in the mining district of Placer de Guadelupe and Puerto del Aire, about 40-50 km northeast of Chihuahua City, in the state of Chihuahua. Reserves of U 3 O 8 which were published in January 1977 by Nuclear Exchange Corporation of Menlo Park, California, are listed. The government of Mexico has not estimated potential resources. It should be noted that much of Mexico appears favourable for uranium, and only 10 percent has been explored. According to NUEXCO (1977), efforts to find uranium are being increased in an attempt to supply Mexico's nuclear reactor requirements through 1990. Activity is reported to be centered in Tamaulipas and Chihuahua states and to a lesser extent in Nueva Leon, Sonora, Coahuila, and Baja California. Major effort will continue to be placed in Chihuahua state to supply the Penna Bianca mill. Correspondence between favorable geological settings for uranium and the geologic regions of Mexico is reported. Mexico is a country with considerable areas that appear promising for discovery of sandstone, vein, and tuff-related deposits. On the other hand, its potential for Precambrian conglomerate and unconformity-related deposits is limited. Considering these geologic factors, as well as the relatively limited amount of exploration done to date, a guesstimate of speculative

Family structure and child anemia in Mexico.

Science.gov (United States)

Schmeer, Kammi K

2013-10-01

Utilizing longitudinal data from the nationally-representative Mexico Family Life Survey, this study assesses the association between family structure and iron-deficient anemia among children ages 3-12 in Mexico. The longitudinal models (n = 4649), which control for baseline anemia status and allow for consideration of family structure transitions, suggest that children living in stable-cohabiting and single-mother families and those who have recently experienced a parental union dissolution have higher odds of anemia than those in stable-married, father-present family structures. Interaction effects indicate that unmarried family contexts have stronger associations with anemia in older children (over age five); and, that the negative effects of parental union dissolution are exacerbated in poorer households. Resident maternal grandparents have a significant beneficial effect on child anemia independent of parental family structure. These results highlight the importance of family structure for child micronutrient deficiencies and suggest that understanding social processes within households may be critical to preventing child anemia in Mexico.

Pérez-Rodríguez, Miguel A.; Adeleke, Monsuru A.; Orozco-Algarra, María E.; Arrendondo-Jiménez, Juan I.; Guo, Xianwu

Background In Latin America, there are 13 geographically isolated endemic foci distributed among Mexico, Guatemala, Colombia, Venezuela, Brazil and Ecuador. The communities of the three endemic foci found within Mexico have been receiving ivermectin treatment since 1989. In this study, we predicted the trend of occurrence of cases in Mexico by applying time series analysis to monthly onchocerciasis data reported by the Mexican Secretariat of Health between 1988 and 2011 using the software R. Results A total of 15,584 cases were reported in Mexico from 1988 to 2011. The data of onchocerciasis cases are mainly from the main endemic foci of Chiapas and Oaxaca. The last case in Oaxaca was reported in 1998, but new cases were reported in the Chiapas foci up to 2011. Time series analysis performed for the foci in Mexico showed a decreasing trend of the disease over time. The best-fitted models with the smallest Akaike Information Criterion (AIC) were Auto-Regressive Integrated Moving Average (ARIMA) models, which were used to predict the tendency of onchocerciasis cases for two years ahead. According to the ARIMA models predictions, the cases in very low number (below 1) are expected for the disease between 2012 and 2013 in Chiapas, the last endemic region in Mexico. Conclusion The endemic regions of Mexico evolved from high onchocerciasis-endemic states to the interruption of transmission due to the strategies followed by the MSH, based on treatment with ivermectin. The extremely low level of expected cases as predicted by ARIMA models for the next two years suggest that the onchocerciasis is being eliminated in Mexico. To our knowledge, it is the first study utilizing time series for predicting case dynamics of onchocerciasis, which could be used as a benchmark during monitoring and post-treatment surveillance.

In this work the analysis of strengths, opportunities, vulnerabilities and threats (SOVT) of the nuclear industry in Mexico is presented. This industry presents among its strengths that Mexico is a highly electrified country and has a good established normative mark of nuclear security. Although the Secretaria de Energia in Mexico, with base to the exposed in the Programa Sectorial de Energia 2007-2012, is analyzing the convenience of the generation starting from this source, considering the strong technological dependence of the exterior and the limited federal budget dedicated to this field. As a result of the analysis of the SOVT matrix, were found a great number of strengths that threats, although the vulnerabilities list is major to the strengths, the opportunities list is the bigger. Therefore, the nuclear industry can be a sustainable industry, taking the necessary decisions and taking advantage of the detected opportunities. (Author)

Rosales-Martínez, Yetzi; Nigenda, Gustavo; Galárraga, Omar; Ruiz-Larios, José Arturo

2010-01-01

To analyze the factors associated with the expectations to migrate abroad among nursing students in Mexico City. A cross-sectional study was conducted with a non-random sample of 420 students. A logistic regression model was estimated. A total of 69% of the informants expressed their intention to move abroad, to look for employment (65%) and/or to continue their studies (26%). Of those, 50% would choose Canada as their destination, followed by Spain and the United States. The variables associated with migration expectations were: age, income, having relatives abroad, and perception of poor labor conditions and low wages in Mexico. Results are consistent with international literature. Low wages, poor labor conditions and the limited possibilities for professional development in Mexico are factors that contribute to generate migration expectations among nursing students. Additionally, optimistic perceptions about the job market and the labor demand in more developed countries heighten expectations to migrate.

Genetic signature analysis of Perkinsus marinus in Mexico suggests possible translocation from the Atlantic Ocean to the Pacific coast of Mexico.

The protozoan Perkinsus marinus (Mackin, Owen & Collier) Levine, 1978 causes perkinsosis in the American oyster Crassostrea virginica Gmelin, 1791. This pathogen is present in cultured C. virginica from the Gulf of Mexico and has been reported recently in Saccostrea palmula (Carpenter, 1857), Crassostrea corteziensis (Hertlein, 1951) and Crassostrea gigas (Thunberg, 1793) from the Mexican Pacific coast. Transportation of fresh oysters for human consumption and repopulation could be implicated in the transmission and dissemination of this parasite across the Mexican Pacific coast. The aim of this study was two-fold. First, we evaluated the P. marinus infection parameters by PCR and RFTM (Ray's fluid thioglycollate medium) in C. virginica from four major lagoons (Términos Lagoon, Campeche; Carmen-Pajonal-Machona Lagoon complex, Tabasco; Mandinga Lagoon, Veracruz; and La Pesca Lagoon, Tamaulipas) from the Gulf of Mexico. Secondly, we used DNA sequence analyses of the ribosomal non-transcribed spacer (rNTS) region of P. marinus to determine the possible translocation of this species from the Gulf of Mexico to the Mexican Pacific coast. Perkinsus marinus prevalence by PCR was 57.7% (338 out of 586 oysters) and 38.2% (224 out of 586 oysters) by RFTM. The highest prevalence was observed in the Carmen-Pajonal-Machona Lagoon complex in the state of Tabasco (73% by PCR and 58% by RFTM) and the estimated weighted prevalence (WP) was less than 1.0 in the four lagoons. Ten unique rDNA-NTS sequences of P. marinus [termed herein the "P. marinus (Pm) haplotype"] were identified in the Gulf of Mexico sample. They shared 96-100% similarity with 18 rDNA-NTS sequences from the GenBank database which were derived from 16 Mexican Pacific coast infections and two sequences from the USA. The phylogenetic tree and the haplotype network showed that the P. marinus rDNA-NTS sequences from Mexico were distant from the rDNA-NTS sequences of P. marinus reported from the USA. The ten r

Background In high-income countries (HICs), higher neighborhood socioeconomic deprivation is associated with higher levels of smoking. Few studies in low- and middle-income countries (LMICs) have investigated the role of the neighborhood environment on smoking behavior. Objective To determine whether neighborhood socioeconomic deprivation is related to smoking intensity, quit attempts, quit success, and smoking relapse among a cohort of smokers in Mexico from 2010–2012. Methods Data were analyzed from adult smokers and recent ex-smokers who participated in Waves 4–6 of the International Tobacco Control (ITC) Mexico Survey. Data were linked to the Mexican government’s composite index of neighborhood socioeconomic deprivation, which is based on 2010 Mexican Census data. We used generalized estimating equations to determine associations between neighborhood deprivation and individual smoking behaviors. Findings Contrary to past findings in HICs, higher neighborhood socioeconomic deprivation was associated with lower smoking intensity. Quit attempts showed a U-shaped pattern whereby smokers living in high/very high deprivation neighborhoods and smokers living in very low deprivation neighborhoods were more likely to make a quit attempt than smokers living in other neighborhoods. We did not find significant differences in neighborhood deprivation on relapse or successful quitting, with the possible exception of people living in medium-deprivation neighborhoods having a higher likelihood of successful quitting than people living in very low deprivation neighborhoods (p=0.06). Conclusions Neighborhood socioeconomic environments in Mexico appear to operate in an opposing manner to those in HICs. Further research should investigate whether rapid implementation of strong tobacco control policies in LMICs, as occurred in Mexico during the follow-up period, avoids the concentration of tobacco-related disparities among socioeconomically disadvantaged groups.

Helping eradicate the medfly from Mexico

International Nuclear Information System (INIS)

LaBrecque, G.

1982-01-01

The Mediterranean fruit-fly (Medfly) is a serious pest in Agriculture. It causes damage primarily by its larvae, which feed on the host fruit or vegetable. Agricultural production of about 30 km 2 can be infested in 100 days by the progeny of 1000 females. In Mexico, the Medfly was first observed in 1977. It severely damages the agricultural economy and limits the trade balance and food supplies of the country. Realizing the gravity of the problem, the IAEA, in co-operation with the Governments of Mexico and the United States, implemented a joint pest management programme under the code-name of MOSCAMED. It utilized the Sterile Insect Technique (SIT) on which the Agency has gained considerable experience from its previous involvements in many developing countries. The SIT is technically suitable and environmentally acceptable for Medfly eradication. A factory was built with all areas of SIT expertise. This factory could produce 2 thousand million Medfly eggs in 12 days. The Agency, including its Seibersdorf laboratory, was the primary back-up of the programme. As a result, the northward migration of the fly has been halted and the pest that had infested over 3 million hectares has been eradicated from Mexico as from early 1981

Because of a steady depletion of reserves and the failure to make new discoveries in recent years, production of crude oil in New Mexico declined in 1979 with a production of 74.7 million bbls (barrels), which was 3.4 million bbls or 4.6 percent less than 1978 production. Although condensate production increased slightly over the previous year, total crude and condensate production continued to decline. Natural-gas production increased in 1979 by 3,565,351 thousand cu ft or 4 percent from the previous year, with an increase in production occurring in northwest New Mexico. Drilling continued to increase as the total number of well completions in New Mexico in 1979 was the highest in the past 9 yrs. Primary and secondary crude oil reserves were calculated for 50 major pools in southeast New Mexico and for selected oil and gas wells in northwest New Mexico. Coal production increased 1.8 million tons in 1979 or 14 percent over 1978 production, and a more extensive expansion will depend partly on factors such as the availability of rail transportation to new areas. The development of synthetic fuel technology may have a substantial impact on longer term coal production. Production of U 3 O 8 declined 13 percent from 1978 with 7420 tons U 3 O 8 reported as production in 1979. A depressed uranium market and other economic factors contributed to the decline in production. New Mexico, however, continues to lead the nation in production and uranium reserves. Researchers are continuing to explore geothermal energy applications and to characterize geothermal systems in the state, and the US Bureau of Land Management has issued 126 geothermal leases that remain active. Recent geothermal exploration activity has been detailed for 14 companies

This paper presents the bases for the Model of Energy and Greenhouse Emission Scenarios (MEEEM) developed by the Instituto de Ingenieria de la UNAM (Universidad Nacional Autonoma de Mexico`s Engineering Institute). This model was built with the objective of analyzing the different technological options for the mitigation of the greenhouse gases effect on Mexico. The MEEEM is a model for the end uses that simulate in a simple way the energy demand, transformation and supply and calculates the differential leveled costs among a basic scenario and several mitigation scenarios of the greenhouse emissions. The article also presents some of the results in evaluating three technologies of renewable energy sources. Although the model is perfectible, its development shows its usefulness in this type of models in the decision taking for the energy and environmental planning of the country.

In 2011, a bi-national student-run free clinic for the underserved, known as "Health Frontiers in Tijuana" (HFiT), was created in Tijuana, Mexico. Students and faculty from one Mexican and one US medical school staff the clinic and attend patients on Saturdays. Students from both medical schools enroll in a didactic course during the quarter/semester that they attend the free clinic. The course addresses clinical, ethical, cultural, population-specific issues and the structure, financing and delivery of medical care in Mexico. The clinic implements an electronic medical record and is developing telemedicine for consulting on complex cases. Despite challenges related to sustaining adequate funding, this program may be replicated in other border communities.

The goal of this study was to quantify the economic role of dairy farming in New Mexico and to identify its linkages with allied industries in terms of income, value added, and employment impacts. An input-output model was used to estimate the direct, indirect, and induced impacts of the dairy farm industry on the economy of New Mexico. The results showed that in 2005, New Mexico's dairy farm industry had a total economic impact of $1.98 billion and accounted for 14,313 jobs. Therefore, dairy farming in New Mexico had an output multiplier (income) of 1.92, a labor income multiplier of $248 thousand/$ million of gross sales, and an employment multiplier of 13.91 jobs/$ million of gross sales. Furthermore, the New Mexico dairy farms accounted for 13.1% of the total agricultural outputs, 20.5% of the agricultural jobs, 1.5% of total state economic activity, and $80 million in tax revenue. With the exception of Lea, Eddy, and Bernalillo counties, which are diversified, the dairy farms accounted for more than two-thirds of the agricultural outputs and for more than two-fifths of the agricultural employment in counties where dairy farms are concentrated.

The future of fuel cell in Mexico in the third millennium

Science.gov (United States)

Ramírez-Salgado, J.; Marín-Cruz, J.; Estrada-Martínez, A.

The warming of the earth due to green house gas emission is mainly produced by CO 2. In Mexico City, 71% of the total harmful emissions is from internal combustion engines of car and buses. Benefits from the use of fuel cells (FCs) in transportation and stationary power generating sectors will achieve satisfactory air quality standards not only in Mexico City but also throughout the country. This paper suggests a scenario for FC technology penetration in Mexico. There are two potential markets for FCs: (i) FC transportation; and (ii) stationary power plant for electrical production. In Mexico City, 3.2 million vehicles are in circulation and represent 19.5% (16.3 million) of the country's total vehicles, and 9.02 million of natural gas users are a potential market for acquiring stationary power generation by FC systems.

Gray fox (Urocyon cinereoargenteus parasite diversity in central Mexico

Full Text Available Mexico has a long history of parasitological studies in communities of vertebrates. However, the mega diversity of the country makes fauna inventories an ongoing priority. Presently, there is little published on the parasite fauna of gray foxes (Urocyon cinereoargenteus Schereber, 1775 and this study provides new records of parasites for gray foxes in central Mexico. It is a continuation of a series of previous parasitological studies conducted with this carnivore in Mexico from 2003 to the present. A total of 24 foxes in the Parque Nacional El Cimatario (PANEC were trapped, anaesthetized, and parasites recovered. The species found were Dirofilaria immitis, Ctenocephalides canis, C. felis, Euhoplopsillus glacialis affinis (first report for gray foxes in Mexico Pulex simulants, and Ixodes sp. Three additional gray fox carcasses were necropsied and the parasites collected were adult nematodes Physaloptera praeputialis and Toxocara canis. The intensive study of the gray fox population selected for the 2013–2015 recent period allowed for a two-fold increase in the number of parasite species recorded for this carnivore since 2003 (nine to 18 parasite species, mainly recording parasitic arthropods, Dirofilaria immitis filariae and adult nematodes. The parasite species recorded are generalists that can survive in anthropic environments; which is characteristic of the present ecological scenario in central Mexico. The close proximity of the PANEC to the city of Santiago de Queretaro suggests possible parasite transmission between the foxes and domestic and feral dogs. Furthermore, packs of feral dogs in the PANEC might have altered habitat use by foxes, with possible impacts on transmission.

The use of medicinal plants in Mexico has been documented since pre-Hispanic times. Nevertheless, the level of use of medicinal plants by health professionals in Mexico remains to be explored. To evaluate the use, acceptance and prescription of medicinal plants by health professionals in 9 of the states of Mexico. Direct and indirect interviews, regarding the use and acceptance of medicinal plants, with health professionals (n=1614), including nurses, physicians, pharmacists, and odontologists from nine states in Mexico were performed from January 2015 to July 2016. The interviews were analyzed with the factor the informant consensus (FIC). The information obtained indicated that 46% of those interviewed feel patients should not use medicinal plants as an alternative therapy. Moreover, 54% of health professionals, and 49% of the physicians have used medicinal plants as an alternative therapy for several diseases. Twenty eight percent of health professionals, and 26% of the physicians, have recommended or prescribed medicinal plants to their patients, whereas 73% of health professionals were in agreement with receiving academic information regarding the use and prescription of medicinal plants. A total of 77 plant species used for medicinal purposes, belonging to 40 botanical families were reported by the interviewed. The results of the FIC showed that the categories of diseases of the digestive system (FIC=0.901) and diseases of the respiratory system (FIC=0.898) had the greatest agreement. This study shows that medicinal plants are used for primary health care in Mexico by health professionals. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

Mexico: Imports or exports?

International Nuclear Information System (INIS)

Estrada, J.

2002-01-01

This presentation provides an overview of Mexico's energy sector. Proven oil reserves place Mexico in ninth position in the world and fourth largest in natural gas reserves. Energy is one of the most important economic activities of the country, representing 3 per cent of Gross Domestic Product (GDP). Oil exports represent 8.4 per cent of total exports. Approximately 40 per cent of total public investment is earmarked for energy projects. The author discusses energy resources and energy sector limitations. The energy sector plan for the period 2001-2006 is discussed. Its goals are to ensure energy supply, to develop the energy sector, to stimulate participation of Mexican enterprises, to promote renewable energy sources, and to strengthen international energy cooperation. The regulatory framework is being adapted to increase private investment. Some graphs are presented, displaying the primary energy production and primary energy consumption. Energy sector reforms are reviewed, as are electricity and natural gas reforms. The energy sector demand for 2000-2010 and investment requirements are reviewed, as well as fuel consumption for power generation. The author discusses the National Pipeline System (SNG) and the bottlenecks caused by pressure efficiency in the northeast, flow restriction on several pipeline segments, variability of the Petroleos Mexicanos (PEMEX) own use, and pressure drop on central regions. The entire prospect for natural gas in the country is reviewed, along with the Strategic Gas Program (PEG) consisting of 20 projects, including 4 non-associated natural gas, 9 exploration and 7 optimization. A section dealing with multiple service contracts is included in the presentation. The authors conclude by stating that the priority is a national energy policy to address Mexico's energy security requirements, to increase natural gas production while promoting the diversification of imports, and a regulatory framework to be updated in light of current

[Fertility change in Mexico and the politics of population].

Science.gov (United States)

Zavala De Cosio, M E

1993-01-01

This introduction to a detailed study of fertility change in Mexico assesses the available fertility data and describes the sources used, traces the beginning and course of the demographic transition in Mexico, and describes the work. Mexico's demographic transition began around 1930 with the acceleration of mortality decline. The considerable time lag between the mortality decline and the beginning of the fertility decline resulted in a period of very rapid growth. Between 1955 and 1975, the growth rate exceeded 3% annually. The start of the fertility decline dated to about 1970, the time of a major reform of population policy and creation of institutions to reduce growth. But the fertility decline was not solely the result of population programs. An incipient fertility decline could be observed in the metropolitan and more educated population sectors beginning in the early 1960s. The onset of the mortality decline in the 1930s resulted from the sustained social and economic progress made possible after the conclusion of the Mexican Revolution. Between 1930 and 1980, the adult illiteracy rate declined from 61.2% to 17%, while life expectancy increased from 33 years to 63.2 years. In Mexico as in other Latin American countries, the mortality decline, which disturbed the traditional balance between high mortality and high fertility, was the force setting off the demographic transition and the necessary precursor to fertility decline. The first of two main sections of the book focuses on examination of fertility variations in Mexico since around 1900 using cross-sectional and longitudinal methods of analysis. The second part describes the origins, history, and institutions involved in Mexico's population policies and the demographic programs and their principal results. The influence of population policies in demographic change is assessed, especially in the case of fertility changes induced by family planning programs. Both the first and second parts sought to place

A Hazy Day in Mexico City

Science.gov (United States)

2002-01-01

Mexico City has one of the world's most serious air pollution problems. The city is located atop a high plain at an altitude of 2200 meters, and is surrounded on three sides by mountains and snow-capped volcanoes. Since incident solar radiation does not vary significantly with season at tropical latitudes, photochemical smog is produced much of the year. In winter, air quality can worsen significantly when thermal inversions keep polluted air masses close to the surface.Atmospheric particulates (aerosols) are readily visible at oblique view angles, and differences in aerosol amount on two days are indicated by these images of central Mexico from the Multi-angle Imaging SpectroRadiometer (MISR). The images at left and center are natural color views acquired by MISR's 70-degree forward-viewing camera on April 9 and December 5, 2001, respectively. Mexico City can be identified in the center panel by the large area of haze accumulation above image center. Two small brighter patches within the hazy area indicate low fog. In the left-hand panel, the city basin appears significantly clearer, but some haze remains apparent across the Sierra Madre mountains in the lower portion of the images. On the right is an elevation field corresponding to the December 5 view. Automated MISR stereoscopic retrievals reveal the clouds at lower right to be at very high altitudes, in contrast to the low-lying haze and fog near Mexico City. When the stereo retrieval determines that a location is not covered by clouds, digital terrain elevation data are displayed instead. High clouds appear as the orange and red areas, and mountainous areas appear light blue and green. The position of the clouds within the 70-degree image are slightly southward of their location in the elevation map as a consequence of geometric parallax.Major sources of air pollutants within the basin enclosing the Mexico City urban area include exhaust from 3.5 million vehicles, thousands of industries, and mineral dust

In Mexico, organochlorine pesticides were used in public health and agriculture programs, causing chronic exposure to the population. Human breast milk samples were collected from 171 mothers who were residents from Guerrero, Mexico. Analysis was carried out by gas chromatography. Median concentrations (mg/kg on fat basis) for the following pesticides were: HCB, 0.009; β-HCH, 0.004; pp'DDE, 0.760; op'DDT, 0.016; pp'DDT, 0.045; and Σ-DDT, 0.833. These values are lower than in other States in Mexico, and in some countries where the use of these pesticides was banned more than 30 years ago. Differences were found in HCB, pp'DDE and pp'DDT concentrations in groups divided according to age (p pesticide levels in human milk is expected in a few years.

Exploring the Association of Homicides in Northern Mexico and Healthcare Access for US Residents.

Science.gov (United States)

Geissler, Kimberley H; Becker, Charles; Stearns, Sally C; Thirumurthy, Harsha; Holmes, George M

2015-08-01

Many legal residents in the United States (US)-Mexico border region cross from the US into Mexico for medical treatment and pharmaceuticals. We analyzed whether recent increases in homicides in Mexico are associated with reduced healthcare access for US border residents. We used data on healthcare access, legal entries to the US from Mexico, and Mexican homicide rates (2002-2010). Poisson regression models estimated associations between homicide rates and total legal US entries. Multivariate difference-in-difference linear probability models evaluated associations between Mexican homicide rates and self-reported measures of healthcare access for US residents. Increased homicide rates were associated with decreased legal entries to the US from Mexico. Contrary to expectations, homicides did not have significant associations with healthcare access measures for legal residents in US border counties. Despite a decrease in border crossings, increased violence in Mexico did not appear to negatively affect healthcare access for US border residents.

Update of Geothermics in Mexico

2004-12-01

Four geothermal fields are currently operating in Mexico (Cerro Prieto, Los Azufres, Los Humeros and Las Tres Virgenes), with a total installed geothermal-electric capacity of 953 megawatts (MW). This means the country is located in third place, worldwide, just behind the USA and Philippines. Thirty-six power plants of several types (condensing, back pressure and binary cycle), between 1.5 and 110 MW, operate in the fields, fed by 197 wells with a combined production of 7,700 metric tons of steam per hour (t/h). These production wells have depths between 600 and 4,400 meters. Steam comes with 8,750 t/h of brine that is injected through 19 injection wells or treated in a solar evaporation pond of 14 km2 in Cerro Prieto. During 2003, steam produced in those fields equaled 67.5 million metric tons, and the power plants generated 6,282 gigawatt-hours (GWh), which represented 3.1% of the electric energy produced in Mexico. All the power plants and the geothermal fields are operated bye the public utility, the Comision Federal de Electricidad (Comision Federal de Electricidad (CFE)).

Pan-American Highways: American Tourism to Mexico and 1950s Hollywood film

Directory of Open Access Journals (Sweden)

Stephanie Fuller

2014-10-01

Full Text Available This article examines American films from the early 1950s which feature journeys to Mexico.  Movies such as Where Danger Lives (John Farrow, 1950, Gun Crazy (Joseph H. Lewis, 1950, Out of the Past (Jacques Tourneur, 1947 and Wetbacks (Hank McCune, 1954 present journeys to Mexico as escapes from American life in which romanticised freedom is closely connected to mobility and automobiles.  The article explores the connection between the films’ cinematic vistas of Mexican landscapes and American tourism to Mexico in this period.  Through their journeys to and across the border, these films call the wider relationship between the US and Mexico into question as national identities are constructed through travel, landscape and touristic encounters.

1989-01-01

Industrialization and its concomitant social and environmental effects in developing countries are considered in this paper. Mexico offers one example of economic progress achieved through the promotion of industrial growth. Recognising the need for trained experts with global experience in occupational health, the University of Arizona (UA) has begun a programme to train occupational and preventive medicine residents in international aspects of occupational health in the nearby industrialized border regions of Mexico. By using the maquiladora (assembly plant) industries and the resources of the Instituto Mexicano del Seguro Social with the State of Sonora, residents observe existing problems in occupational safety and health in addition to adding to their understanding of the need for worldwide cooperation for research and reform in this field.

Full Text Available A 50-year-old mining engineer at Dhanbad was having air bome contact Dermatitis suspected to be caused by Xanthium strumarium. Patch tests with a 15% aqueous extract of air dried leaves showed a severe positive reaction, but the patient also had positive patch tests with Parthenium hysterphorus and a few other weeds and trees known to cause air-borne contact dermatitis. The titre of contact hypersensitivity with the extract of Xanthium struma′rium was more than 1:100,000 and for Parthenium hysterophrous it was 1:10 indicating a high degree of hypersensitivity to Xanthium strumarium. Further tests in 14 other patients revealed a high prevalence of cross sensitivity between these two plants both of which belong to the compositae family.

Sánchez-Montes, Sokani; Espinosa-Martínez, Deborah V.; Ríos-Muñoz, César A.; Berzunza-Cruz, Miriam; Becker, Ingeborg

2015-01-01

Background Leptospirosis is widespread in Mexico, yet the potential distribution and risk of the disease remain unknown. Methodology/Principal Findings We analysed morbidity and mortality according to age and gender based on three sources of data reported by the Ministry of Health and the National Institute of Geography and Statics of Mexico, for the decade 2000–2010. A total of 1,547 cases were reported in 27 states, the majority of which were registered during the rainy season, and the most affected age group was 25–44 years old. Although leptospirosis has been reported as an occupational disease of males, analysis of morbidity in Mexico showed no male preference. A total number of 198 deaths were registered in 21 states, mainly in urban settings. Mortality was higher in males (61.1%) as compared to females (38.9%), and the case fatality ratio was also increased in males. The overall case fatality ratio in Mexico was elevated (12.8%), as compared to other countries. We additionally determined the potential disease distribution by examining the spatial epidemiology combined with spatial modeling using ecological niche modeling techniques. We identified regions where leptospirosis could be present and created a potential distribution map using bioclimatic variables derived from temperature and precipitation. Our data show that the distribution of the cases was more related to temperature (75%) than to precipitation variables. Ecological niche modeling showed predictive areas that were widely distributed in central and southern Mexico, excluding areas characterized by extreme climates. Conclusions/Significance In conclusion, an epidemiological surveillance of leptospirosis is recommended in Mexico, since 55.7% of the country has environmental conditions fulfilling the criteria that favor the presence of the disease.

2017-10-01

Rocky Mountain spotted fever (RMSF) is an emerging public health concern near the US-Mexico border, where it has resulted in thousands of cases and hundreds of deaths in the past decade. We identified 4 patients who had acquired RMSF in northern Mexico and subsequently died at US healthcare facilities. Two patients sought care in Mexico before being admitted to US-based hospitals. All patients initially had several nonspecific signs and symptoms, including fever, headache, nausea, vomiting, or myalgia, but deteriorated rapidly without receipt of a tetracycline-class antimicrobial drug. Each patient experienced respiratory failure late in illness. Although transborder cases are not common, early recognition and prompt initiation of appropriate treatment are vital for averting severe illness and death. Clinicians on both sides of the US-Mexico border should consider a diagnosis of RMSF for patients with rapidly progressing febrile illness and recent exposure in northern Mexico.

Why are we resentment of Mexico in the United States?

Directory of Open Access Journals (Sweden)

Josué Sánchez

2009-04-01

Full Text Available The essay engages into a cultural analysis of Mexico from a populist foreign perspective. The complaints of some Latin Americans on the cultural imposition of Mexico are inserted in this cultural overview. Systematically several cultural aspects that cause resentment against México are discussed throughout the essay. A pattern of cultural “mexicanization” which eventually becomes an imposition by the great masses of Mexicans in Mexico, as well as the ones living in the United States, becomes obvious. It is a matter of the exportation of Mexican culture on the Latin American cultures in a disproportionate manner. It is an exposition of Mexican culture through complaints of Latin-Americans searching for a cultural equilibrium.

Neurocysticercosis, a persisting health problem in Mexico.

Directory of Open Access Journals (Sweden)

Agnès Fleury

Full Text Available BACKGROUND: The ongoing epidemiological transition in Mexico minimizes the relative impact of neurocysticercosis (NC on public health. However, hard data on the disease frequency are not available. METHODOLOGY: All clinical records from patients admitted in the Instituto Nacional de Neurologia y Neurocirugia (INNN at Mexico City in 1994 and 2004 were revised. The frequencies of hospitalized NC patients in neurology, neurosurgery and psychiatry services, as well as NC mortality from 1995 through 2009, were retrieved. Statistical analyses were made to evaluate possible significant differences in frequencies of NC patients' admission between 1994 and 2004, and in yearly frequencies of NC patients' hospitalization and death between 1995 and 2009. PRINCIPAL FINDINGS: NC frequency in INNN is not significantly different in 1994 and 2004. Between these two years, clinical severity of the cases diminished and the proportion of patients living in Mexico City increased. Yearly frequencies of hospitalization in neurology and psychiatry services were stable, while frequencies of hospitalization in neurosurgery service and mortality significantly decreased between 1995 and 2009. CONCLUSIONS: Our findings show a stable tendency of hospital cases during the last decade that should encourage to redouble efforts to control this ancient disease.

Northern New Mexico regional airport market feasibility

Energy Technology Data Exchange (ETDEWEB)

Drake, R.H.; Williams, D.S.

1998-06-01

This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

The Valley of Mexico presents important challenges for air quality modeling: complex terrain, a great variety of anthropogenic and natural emissions sources, and high altitude and low latitude increasing the amount of radiation flux. The modeling group at the CCA-UNAM is using and merging state of the art models to study the different aspects that influence the air quality phenomenon in the Valley of Mexico. The air quality model MCCM that uses MM5 as its meteorological input has been a valuable tool to study important features of the complex and intricate atmospheric flows on the valley, such as local confluences and vertical fumigation. Air quality modeling has allowed studying the interaction between the atmospheres of the valleys surrounding the Valley of Mexico, prompting the location of measurement stations during the MILAGRO campaign. These measurements confirmed the modeling results and expanded our knowledge of the transport of pollutants between the Valleys of Cuernavaca, Puebla and Mexico. The urban landscape of Mexico City complicates meteorological modeling. Urban-MM5, a model that explicitly takes into account the influence of buildings, houses, streets, parks and anthropogenic heat, is being implemented. Preliminary results of urban-MM5 on a small area of the city have been obtained. The current emissions inventory uses traffic database that includes hourly vehicular activity in more than 11,000 street segments, includes 23 area emissions categories, more than 1,000 industrial sources and biogenic emissions. To improve mobile sources emissions a system consisting of a traffic model and a car simulator is underway. This system will allow for high time and space resolution and takes into account motor stress due to different driving regimes. An important source of emissions in the Valley of Mexico is erosion dust. The erosion model WEPS has been integrated with MM5 and preliminary results showing dust episodes over Mexico City have been obtained. A

Full text: We describe in this paper the results obtained by the project 'Radiological analysis of environmental samples in some points of the coast of the Gulf of Mexico and coast of Quintana Roo, Mexico'. The purpose of the study is to identify and quantify the natural and anthropogenic radionuclides present from sediments, sand and seawater from several sites located along the coast of the Gulf of Mexico and the Caribean Sea. The samples are analysed in a Canberra Multichannel analyzer system for gamma spectrometry, equipped with a detector of hyper pure germanium and a Genie 2000 software, in the 'Laboratory of Radiological Analysis of Environmental Samples', belonging to the Physics Department, Faculty of Sciences, National Autonomous University of Mexico (UNAM). The geographic sites were samples were taken include the states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan and Quintana Roo. The results of this studies will be published at the end of the project and we hope they will be useful for the national health and industrial sectors. Until now we have identified and measured the presence of natural radionuclides such as Potassium-40 (K-40), Bismuth 212 (Bi-212), Lead-212 (Pb-212), Bismuth-214 (Bi-214), Lead-214 (Pb-214), Radium-226 (Ra-226), Actinium 228 (Ac-228), Uranium-235 (U-235), as well as some anthropogenic radionuclides found near the Laguna Verde Nuclear Power Plant. The project is scheduled to last for three years, finishing in 2009. At its ending we shall be able to present conclusions and identify some tendencies, in connection with the background and possible radioactive contamination of the studied zones. This project takes place under the auspice of the 'Program of Support to Projects of Research and Technological Innovation' of the National Autonomous University of Mexico. (author)

The understanding of historic hydroclimatic variability is basic for planning proper management of limited water resources in northeastern Mexico. The objective of this study was to develop a network of tree-ring chronologies to reconstruct hydroclimate variability in northeastern Mexico and to analyze the influence of large-scale circulation patterns, such as ENSO. Precipitation sensitive tree-ring chronologies of Douglas-fir were developed in mountain ranges of the Sierra Madre Oriental and used to produce winter-spring precipitation reconstructions for central and southern Nuevo Leon, and southeastern Coahuila. The seasonal winter-spring precipitation reconstructions are 342 years long (1659-2001) for Saltillo, Coahuila and 602 years long (1400-2002) for central and southern Nuevo Leon. Both reconstructions show droughts in the 1810s, 1870s, 1890s, 1910s, and 1970s, and wet periods in the 1770s, 1930s, 1960s, and 1980s. Prior to 1800s the reconstructions are less similar. The impact of ENSO in northeastern Mexico (as measured by the Tropical Rainfall Index) indicated long-term instability of the Pacific equatorial teleconnection. Atmospheric circulation systems coming from higher latitudes (cold fronts or 'nortes') and others developed in the Gulf of Mexico (tropical storms, hurricanes) also influence the climatic conditions characterizing this region. The recent development of new and longer tree-ring chronologies for the region will contribute to a better understanding of the interannual and multidecadal climatic variability of northeastern Mexico.

To describe the approval process and implementation of the 100% smokefree law in Mexico City and a competing federal law between 2007 and 2010. Reviewed smokefree legislation, published newspaper articles and interviewed key informants. Strong efforts by tobacco control advocacy groups and key policymakers in Mexico City in 2008 prompted the approval of a 100% smokefree law following the WHO FCTC. As elsewhere, the tobacco industry utilised the hospitality sector to block smokefree legislation, challenged the City law before the Supreme Court and promoted the passage of a federal law that required designated smoking areas. These tactics disrupted implementation of the City law by causing confusion over which law applied in Mexico City. Despite interference, the City law increased public support for 100% smokefree policies and decreased the social acceptability of smoking. In September 2009, the Supreme Court ruled in favour of the City law, giving it the authority to go beyond the federal law to protect the fundamental right of health for all citizens. Early education and enforcement efforts by tobacco control advocates promoted the City law in 2008 but advocates should still anticipate continuing opposition from the tobacco industry, which will require continued pressure on the government. Advocates should utilise the Supreme Court's ruling to promote 100% smokefree policies outside Mexico City. Strong advocacy for the City law could be used as a model of success throughout Mexico and other Latin American countries.

The global prevalence of allergic rhinitis is high. International Study of Asthma and Allergies in Childhood (ISAAC) Phase III reports a total estimated prevalence of 4.6% in Mexico. There is evidence based on allergic rhinitis Clinical Practice Guidelines (CPG), but its promotion, acceptance and application is not optimal or adequate in Mexico. To generate a guideline for the treatment of allergic rhinitis and its impact on asthma by adaptating the 2010 ARIA Guideline to Mexican reality, through a transculturation process applying the ADAPTE methodology. Using the ADAPTE Methodology, the original 2010 ARIA CPG recommendations were evaluated by the guideline development group (GDG) into which multiple medical specialities managing patients with allergic rhinitis were incoorporated. The GDG valorated the quality of 2010 ARIA, checked and translated key clinical questions. Moreover, the GDG adjusted recommendations, patient preferences and included comments in the context of the Mexican reality (safety, costs and cultural issues). To accomplish this, we ran Delphi panels with as many rounds as necessary to reach agreement. One extra question, not included in the original 2010 ARIA, on the use of Nasal Lavages for AR was created sustained by a systematic literature review. A total of 45 questions from the original 2010 ARIA were included and divided into six groups covering prevention, medical treatment, immunotherapy and alternative medicine to treat patients with allergic rhinitis with or without asthma. Most of the questions reached agreement in one or two rounds; one question required three rounds. An easy-to-use, adaptated, up-to-date and applicable allergic rhinitis guideline for Mexico is now available.

2011-05-01

In Mexico City there are more than 22 millions of inhabitants (10 in the metropolitan area and 12 in the suburban zone) exposed to drinking water. The local epidemiological authorities recognised that exposure to radon contaminated drinking water is a potential health hazard, as has been considered worldwide. The United States Environmental Protection Agency has proposed a limit of 11.1 Bq l(-1) for the radon level in drinking water. In Mexico a maximum contamination level of radon in drinking water has not yet even considered. In this work, a (222)Rn study of drinking water in Mexico City has revealed a range of concentrations from background level to 3.8 Bq l(-1). (222)Rn was calculated using a portable degassing system (AquaKIT) associated with an AlphaGUARD measuring system. Samples from 70 wells of the water system of the south of the Valley Basin of Mexico City and from houses of some other political administrative divisions of Mexico City were taken.

The Vital Issues Process, developed by the Sandia National Laboratories Strategic Technologies Department, was utilized by the Health Care Task Force Advisory Group to apply structure to their policy deliberations. By convening three expert panels, an overarching goal for the New Mexico health care system, seven desired outcomes, nine policy options, and 17 action items were developed for the New Mexico health care system. Three broadly stated evaluation criteria were articulated and used to produce relative rankings of the desired outcomes and policy options for preventive care and information systems. Reports summarizing the policy deliberations were submitted for consideration by the Health Care Task Force, a Joint Interim Committee of the New Mexico Legislature, charged with facilitating the development and implementation of a comprehensive health care delivery system for New Mexico. The Task Force reported its findings and recommendations to the Second Session of the 41st New Mexico State Legislature in January 1994.

We provide an updated list of the Recent land mammals of Mexico and include information on the taxonomy of certain species, and where appropriate, the endemic and threatened status of all species listed. Several taxonomic and nomenclatural changes have been made since publication of the last list of the Mexican terrestrial mammalian fauna. Within the period from 2005 to present, there have been at least 209 changes concerning the nomenclature of this fauna; these we evaluated in this paper. The land mammals of Mexico comprise 168 genera, 496 species, and 881 subspecies.

The objective of this document is to present, in a clear and concrete way, the results presented in the book -Nuclear energy an opportunity for Mexico- this book was prepared to evaluate the feasibility of constructing a new nuclear power plant in Mexico considering the evident worldwide rise of the nuclear energy as a way to produce electricity. The worldwide nuclear power renaissance is based on several factors, some of the most important are the uncertainty about the availability and behavior of fossil fuels, the impacts of the green house gases over the environment; improvements in the design and construction process that allow to reduce the construction periods; the competitiveness of nuclear power with other clean technologies and the experience of the nuclear power plant fleet that has shown performance indicators that exceed other technologies. Also, the competitiveness of the nuclear power as base load to satisfy the electricity demand. This book include the actual situation of the nuclear power in the world and the challenges and opportunities to incorporate additional nuclear power plants in Mexico, with the aim of satisfy the future electricity demand, in harmony with the environment and in a secure and safety way. Nonetheless, by itself a nuclear power plant is not the entire or only solution for the environmental and security of supply issues, but nuclear power is a main part of the integral solution where renewable and new clean technologies (e.g. carbon capture and storage and integrated gasification combined cycle) plays an important role. Nowadays, several countries go forward for the use or nuclear power, reinforcing and in some cases restarting their nuclear power programs, Mexico should not be the exception, nuclear power deserves to be included in the portfolio of generation technologies in the future years. The main advantages of nuclear power, as well as the most questionable issues are deeply discussed in the book. (Author)

Sunflower (Helianthus annuus L.) as a pre-Columbian domesticate in Mexico

Lentz, David L.; Pohl, Mary DeLand; Alvarado, José Luis; Tarighat, Somayeh; Bye, Robert

2008-01-01

Mexico has long been recognized as one of the world's cradles of domestication with evidence for squash (Cucurbita pepo) cultivation appearing as early as 8,000 cal B.C. followed by many other plants, such as maize (Zea mays), peppers (Capsicum annuum), common beans (Phaseolus vulgaris), and cotton (Gossypium hirsutum). We present archaeological, linguistic, ethnographic, and ethnohistoric data demonstrating that sunflower (Helianthus annuus) had entered the repertoire of Mexican domesticates by ca. 2600 cal B.C., that its cultivation was widespread in Mexico and extended as far south as El Salvador by the first millennium B.C., that it was well known to the Aztecs, and that it is still in use by traditional Mesoamerican cultures today. The sunflower's association with indigenous solar religion and warfare in Mexico may have led to its suppression after the Spanish Conquest. The discovery of ancient sunflower in Mexico refines our knowledge of domesticated Mesoamerican plants and adds complexity to our understanding of cultural evolution. PMID:18443289

Concentrations of seven metals (As, Cd, Cr, Cu, Pb, Ni, and Zn) were analyzed in 33 bone tissue samples of Antillean manatees (Trichechus manatus manatus) found dead in lagoons and rivers of Tabasco and Campeche in the Gulf of Mexico and Chetumal Bay in the Caribbean region. The concentrations of Cr, Cu, Pb, and Zn were significantly different between regions, with greater levels found in the Gulf of Mexico group than in the Mexican Caribbean group (p < 0.05). Pb concentrations differed significantly between adults and calves. No differences were observed between sexes. Metal concentrations detected in the manatee bones were higher than most of those reported for bones in other marine mammals around the world. Future studies are necessary to establish whether the metal concentrations represent a risk to the health of the species.

For twenty years, the Regional Medfly Program in southern Mexico and Guatemala, central America - which is financed by Mexico, Guatemala and USA - has successfully halted the Medfly (Ceratitis capitata (Wied.)) dispersion toward Mexico and USA. After the pest eradication in Chiapas, Mexico, in 1982 and some vain efforts to contain it in Guatemala, a strategy has been formed in the construction of a static barrier of containment. However, this has been criticised frequently by the border society which has suffered for a long time because detection and control action sometimes result in big emergency plans as the answer to strong explosions and pest dispersions which have in turn occurred from climatic phenomena, such as El Nino, in 1998. The Medfly eradication in Guatemala has not been accomplished because the suppression technology used before sterile insect technique (SIT) had been based on malathion aerial bait spray. The aerial bait spray has been prohibited in Guatemala since 1987, following strong complaints from ecological groups and the beekeeping sector, as well as because of financial constraints. The xanthene dye technology that replaced the use of malathion has given new hopes and possibilities to the old project of pest eradication in Guatemala and Central America. However, moving the barrier from north to south and from east to west is necessary to prevent re-infestations in Mexico and pest-free areas in Guatemala. The development of new detection and control tools has also strongly supported the project, with the use of more efficient traps, such as the OBDT trap, baited with ammonium acetate, putrescine and trimethylamine (phase IV traps), trimedlure (TML)-laced yellow panel traps and TML-baited Jackson traps. The use of the improved chilled adult release system, the aerial bait sprays which are guided by the GPS and SATLOC navigation systems, the augmentative release of parasitoids and the artificial biological isolation of the infested areas all

Status of geothermal resources in Mexico

1990-01-01

Except for some isolated instances with tourist or therapeutic objectives and some attempts in the Cerro Prieto geothermal field, there are no projects for direct heat utilization of geothermal resources in Mexico. Therefore, all places that are studied are studied with geothermal-electric objectives. It is convenient to keep in mind that in Mexico, by law, the Comision Federal de Electricidad (CFE) is the public utility in charge of electrical energy service. This institution is directly responsible for the exploration, development and commercial use of geothermal energy for electrical generation. Therefore, this paper includes the present and planned exploration and utilization of geothermal resources only for electricity generation for the period 1985 to the present. Likewise, starting 5 years ago, the CFE efforts have been directed toward the development of high enthalpy fields

Vehicles are one of the major vectors of long-distance weed seed spread. Viable seed removed from vehicles at roadside wash down facilities was studied at five locations in central Queensland, Australia over a 3-year period. Seed from 145 plant species, belonging to 34 different families, were identified in the sludge samples obtained from the wet particulate matter collection pit of the wash down facilities. Most of the species were annual forbs (50%) with small or very small seed size (weed was observed in these samples. More parthenium weed seed were found in the Rolleston facility and in the spring, but its seed was present in all facilities and in all seasons. The average number of viable seed found within every ton of dry particulate matter removed from vehicles was ca. 68,000. Thus, a typical wash down facility was removing up to ca. 335,000 viable seed from vehicles per week, of which ca. 6700 were parthenium weed seed. Furthermore, 61% of these seed (ca. 200,000) were from introduced species, and about half of these (35% of total) were from species considered to be weeds. Therefore, the roadside wash down facilities found throughout Queensland can remove a substantial amount of viable weed seed from vehicles, including the invasive parthenium weed, and the use of such facilities should be strongly encouraged.

Tuberculosis (TB) is a leading public health problem and a recognized priority for the federal Governments of both Mexico and the United States of America. The objectives of this research, primarily for the four states in the United States that are along the border with Mexico, were to: (1) describe the epidemiological situation of TB, (2) identify TB risk factors, and (3) discuss tuberculosis program strategies. We analyzed tuberculosis case reports collected from 1993 through 2001 by the tuberculosis surveillance system of the United States. We used those data to compare TB cases mainly among three groups: (1) Mexican-born persons in the four United States border states (Arizona, California, New Mexico, and Texas), (2) persons in those four border states who had been born in the United States, and (3) Mexican-born persons in the 46 other states of the United States, which do not border Mexico. For the period from 1993 through 2001, of the 16 223 TB cases reported for Mexican-born persons in the United States, 12 450 of them (76.7%) were reported by Arizona, California, New Mexico, and Texas. In those four border states overall in 2001, tuberculosis case rates for Mexican-born persons were 5.0 times as high as the rates for persons born in the United States; those four states have 23 counties that directly border on Mexico, and the ratio in those counties was 5.8. HIV seropositivity, drug and alcohol use, unemployment, and incarceration were significantly less likely to be reported in Mexican-born TB patients from the four border states and the nonborder states than in patients born in the United States from the four border states (P pulmonary tuberculosis patients who were 18-64 years of age and residing in the four border states, the Mexican-born patients were 3.6 times as likely as the United States-born patients were to have resistance to at least isoniazid and rifampin (i. e., to have multidrug-resistant TB) and twice as likely to have isoniazid resistance

1997-01-01

During 1996, 56.2 million tons of steam were produced, at an average annual rate of 6,416 tons per hour (t/h), to supply enough steam to operate of 26 geothermal-electric plants in three geothermal fields, which represent an installed capacity of 743 MW. To accomplish that production, 177 geothermal wells were operated at an average annual production of 36 t/h of steam. Electricity generation was 5,737 gigawatts-hour, which represent 3.8% of the whole electrical energy generated in Mexico in 1996. Production of steam and generation of electricity were increased in 1996, comparing with 1994 and 1995. However, unitary costs were practically the same between 1995 and 1996. The Comision Federal de Electricidad (Federal Commission for Electricity, or CFE) has programmed several geothermal- electric projects to increase the installed capacity in the fields under exploitation in new fields. Also, the CFE has some non electrical projects to reach an integral use of geothermics in Mexico. [Espanol] A fin de suministrar el vapor necesario para la generacion de 26 plantas geotermoelectricas instaladas en tres campos geotermicos, con una capacidad total de 743 megawatts (MW) durante 1996 se produjeron 56.2 millones de toneladas de vapor, a una tasa media anual de 6,416 toneladas por hora (t/h). Ello implico la operacion de 177 pozos productores, con una produccion de la energia electrica generada en Mexico en 1996. Tanto la produccion de vapor como la generacion de electricidad en 1996 se incrementaron con respecto a los anos precedentes de 1994 y 1995, pese a que los costos unitarios se mantuvieron practicamente constantes entre 1995 y 1996. La Comision Federal de Electricidad (CFE) tiene en programa varios proyectos geotermoelectricos para incrementar la capacidad instalada en los campos en explotacion y para iniciar el aprovechamiento en campos nuevos, asi como proyectos no electricos para conseguir un aprovechamiento integral de la geotermia en Mexico.

The prehospital emergency care system in Mexico City: a system's performance evaluation.

Peralta, Luis Mauricio Pinet

2006-01-01

Mexico City has one of the highest mortality rates in Mexico, with non-intentional injuries as a leading cause of death among persons 1-44 years of age. Emergency medical services (EMS) in Mexico can achieve high levels of efficiency by offering high quality medical care at a low cost through adequate system design. The objective of this study was to determine whether the prehospital EMS system in Mexico City meets the criteria standards established by the American Ambulance Association Guide for Contracting Emergency Medical Services (AAA Guide) for highly efficient EMS systems. This retrospective, descriptive study, evaluated the structure of Mexico City's EMS system and analyzed EMS response times, clinical capacity, economic efficiency, and customer satisfaction. These results were compared with the AAA guide, according to the soc ial, economic, and political context in Mexico. This paper describes the healthcare system structure in Mexico, followed by a description of the basic structure of EMS in Mexico City, and of each tenet described in the AAA guide. The p aper includesdata obtained from official documents and databases of government agencies, and operative and administrative data from public and private EMS providers. The quality of the data for response times (RT) were insufficient and widely varied among providers, with a minimum RT of 6.79 minutes (min) and a maximum RT of 61 min. Providers did not define RT clearly, and measured it with averages, which can hide potentially poor performance practices. Training institutions are not required to follow a standardized curriculum. Certifications are the responsibility of the individual training centers and have no government regulation. There was no evidence of active medical control involvement in direct patient care, and providers did not report that quality assurance programs were in place. There also are limited career advancement opportunities for EMS personnel. Small economies of scale may not allow

The biophysical perspective of a middle income economy. Material flows in Mexico

International Nuclear Information System (INIS)

Gonzalez-Martinez, Ana Citlalic; Schandl, Heinz

2008-01-01

We analyse natural resource use dynamics in the Mexican economy during the last three decades. Despite low and uneven economic growth, the extraction and use of materials in the Mexican economy has continuously increased during the last 30 years. In this period, population growth rather than economic growth was the main driving force for biophysical growth. In addition, fundamental changes have taken place in the primary sectors, in manufacturing, and in household consumption and these are reflected in an increasing emphasis on the use of fossil fuels and construction materials. Mexico's economy has been strongly influenced by international trade since the country commenced competing in international markets. In the 1970s, Mexico mainly exported primary resources. This pattern has changed and manufactured goods now have a much greater importance due to a boom in assembling industries. In contrast with other Latin American countries, Mexico has achieved a diversification of production, moving towards technology-intensive products and a better mix in its export portfolio. However, crude oil exports still represent the single most important export good. Mexico's material consumption is still well below the OECD average but is growing fast and the current resource use patterns may well present serious social and environmental problems to the medium and long-term sustainability of Mexico's economy and community. Information on natural resource use and resource productivity could provide valuable guidance for economic policy planning in Mexico. (author)

2015-07-01

In Mexico, the Upper Jurassic to lowermost Cretaceous La Casita and coeval La Caja and La Pimienta formations are well-known for their abundant and well-preserved marine vertebrates and invertebrates. The latter include conspicuous inoceramid bivalves of the genus Anopaea not formally described previously from Mexico. Anopaea bassei (Lecolle de Cantú, 1967), Anopaea cf. stoliczkai (Holdhaus, 1913), Anopaea cf. callistoensis Crame and Kelly, 1995 and Anopaea sp. are rare constituents in distinctive Tithonian-lower Berriasian levels of the La Caja Formation and one Tithonian horizon of the La Pimienta Formation. Anopaea bassei was previously documented from the Tithonian of central Mexico and Cuba, while most other members of Anopaea described here are only known from southern high latitudes. The Mexican assemblage also includes taxa which closely resemble Anopaea stoliczkai from the Tithonian of India, Indonesia and the Antarctic Peninsula, and Anopaea callistoensis from the late Tithonian to ?early Berriasian of the Antarctic Peninsula. Our new data expand the palaeogeographical distribution of the high latitude Anopaea to the Gulf of Mexico region and substantiate faunal exchange, in the Late Jurassic-earliest Cretaceous, between Mexico and the Antarctic Realm.

ReEDS-Mexico: A Capacity Expansion Model of the Mexican Power System

This report documents the ReEDS-Mexico capacity expansion model, which is an extension of the ReEDS model to the Mexican power system. In recent years Mexico’s power sector has undergone considerable reform that has significant potential to impact the future electricity mix (Alpizar–Castro and Rodríguez–Monroy 2016). Day-ahead and real-time trading in Mexico’s power markets opened in early 2016. In addition to this reform, Mexico is striving to ensure that 35% of its electricity is generated from clean energy sources by 2024, 40% by 2035, and 50% by 2050 (Presidencia de la República 2016). These rapid changes in both the market and the generation mix create a need for robust tools that can help electricity sector stakeholders make informed decisions. The purpose of this report is to document the extension of the National Renewable Energy Laboratory’s (NREL’s) Regional Energy Deployment System (ReEDS) model (Eurek et al. 2016) to cover the Mexico power system. This extension, which we will refer to throughout this paper as ReEDS-Mexico, provides a model of the Mexico power sector using a system-wide, least-cost optimization framework.
