[Inquérito epidemiológico com paracoccidioidina e histoplasmina em área agrícola de café em Ibiá, Minas Gerais, Brasil.].  


An epidemiological survey in an endemic area for paracoccidioidomycosis in Ibiá town, Minas Gerais state, Brazil was carried out. For this, we used a standard form for each household and intradermal antigens of histoplasmin and paracoccidioidin. Out of 194 individuals, 109(56%) were engaged in the survey showing reactivity of 44% and 49.5% for these antigens respectively. The reactivity to paracoccidioidin was observed in 50% of children below ten years. Individuals who revealed reactivity to paracoccidiodin with prior history of coffee growing activities, and those reporting the grain collection as the main work, showed statistically significant association p = 0.0092, p = 0.0007 and p = 0,01 respectively. These results could suggest that activities related to coffee crops, may favour the transmission of Paracoccidioides brasiliensis, specially among the grain collectors. In addition, the reactivity for histoplasmin antigen, suggest that this region is endemic for both fungi. PMID:18473521

MINA, an IL-4 repressor controls TH2 bias  

PubMed Central

T helper-2 (TH2)-bias, the propensity of naive CD4+ T cells to differentiate into interleukin 4 (IL-4) secreting TH2 cells, is a genetic trait impacting infectious, autoimmune and allergic disease susceptibility. TH2-bias correlates with the amount of IL-4 initially secreted by newly activated TH cells that feeds back positively through the IL-4R-STAT6-GATA3 pathway to drive TH2 development. Here, we identify Mina, a JmjC family member, as a genetic determinant of TH2-bias. Mina specifically bound to and repressed the Il4 promoter. Mina overexpression in transgenic mice impaired Il4 expression, while its knockdown in primary CD4+ T cells led to Il4 derepression. Together, these findings provide mechanistic insight into an Il4 regulatory pathway controlling TH differentiation and genetic variation in TH2-bias.

Senaite, Pb(Ti,Fe,Mn)21O38, a member of the crichtonite group, was first described from alluvial gravels near Dattas, Minas Gerais, Brazil. It was subsequently reported (always from alluvial stream gravels) from about seven additional localities. "Senaite' from the first in situ source in Brazil, at the Fazenda Guariba, Minas Gerais, Brazil was described by Cassedanne (1988). Approximately 20 crystals of "senaite' from the Fazenda Guariba were examined chemically and all were found to be plumboan crichtonite rather than senaite. -from Authors

Mercury concentration in fish from Piracicaba River (Minas Gerais, Brazil).  


Mercury emissions from some upstream gold mining areas and recent findings of high natural Hg levels in sediments motivated studies on the Hg cycle in the Minas Gerais state. The study presents the total mercury amount found in Geophagus brasiliensis' muscular tissue (wet weight) and sediments from Piracicaba River. Mercury was analyzed using acid digestion followed by determination of total mercury by cold vapour atomic absorption spectrophotometry. This study was also complemented with the analysis of the limnological parameters (water temperature, conductivity, total dissolved solids, suspended particles, pH, dissolved oxygen, maximum depth, photic index and total carbon). The mercury concentration in sediments samples was higher than the mercury concentration in muscular tissue of fish. The lowest Hg level measured in fish was 0.0147 microg g( - 1), while the highest was 0.101 microg g( - 1). In the sediment samples, the lowest and highest levels were 0.02 microg g( - 1) and 0.16 microg g( - 1), respectively. The Hg concentrations in fish and sediment were both under the maximum limit permitted by the World Health Organization. PMID:18683058

Ticks (Acari: Ixodidae) on dogs from Uberlândia, Minas Gerais, Brazil.  


Uberlândia in Minas Gerais State, southeastern Brazil, has 622 000 inhabitants and is located in the Cerrado biome, the South American savannah. The city dog population is estimated at 82 000 and identification of tick species and infestation prevalence on this host has not been determined. A major infectious disease of dogs in the city, canine ehrlichiosis, is transmitted by Rhipicephalus sanguineus ticks. At the same time, autochthonous leishmaniosis has been recently described in the city and a role for dog ticks in the disease transmission has been supposed in Brazil. In this work, we present general information on dog ticks in Uberlândia municipality and region. Dogs from 33 farms and 31 districts were examined for ticks from July 2007 to February 2009. On the whole, 413 dogs were examined, 311 (75.3%) from the city and 102 (24.6%) from rural area. Overall infestation rate of dogs from Uberlândia was 37.3% and the mean infestation intensity was 3.25 parasites per dog. In the urban area, 100 dogs (32.2%) had ticks whereas 54 dogs (52.9%) from rural areas were infested. Four tick species were found: Rhipicephalus sanguineus, Amblyomma cajennense, Amblyomma ovale and Boophilus microplus. In the city, only R. sanguineus and one A. cajennense was found on dogs and R. sanguineus and A. ovale were the main dog ticks in rural areas. PMID:20537111

[Schistosomiasis in an ecotourism area in Minas Gerais State, Brazil].  


This paper discusses schistosomiasis transmission in São José da Serra, a village with a population of 500 in the county of Jaboticatubas, Minas Gerais State, Brazil. The area receives thousands of visitors a year for ecotourism. The study was motivated by a case of acute schistosomiasis involving a couple that spent the 2007 Carnival (Mardi Gras) holiday in the area. Stool tests from 268 local residents (53.6% of the population) showed that 35 (13%) were positive for the infection. A comparison with a previous survey (2005) in the same location showed an increase in the schistosomiasis-positive rate from 9.6% to 12.5%, among the 56 individuals who participated in both surveys. A malacological survey of 65 Biomphalaria glabrata snails showed one specimen (1.5%) eliminating cercariae. In a similar survey in 2005, no positive snail specimens were found. The study indicates that active schistosomiasis transmission is occurring in the area, and that integrated educational programs are needed for both the local community and tourists. PMID:18670694

Seroprevalence for Neospora caninum in goats of Minas Gerais state, Brazil.  


This study was aimed at determining the prevalence of anti-Neospora caninum antibodies in serum samples from 667 goats, collected from 90 herds in 90 municipalities in eight of the twelve mesoregions of Minas Gerais State. The presence of anti-N. caninum antibodies was determined by IFAT with a cut-off value of 1:50. The true herd-level seroprevalence in the entire study area was 75.2% (CI 95%: 59.5-90.9%). The true individual-level seroprevalence in the entire study area was 10.7% (CI 95%: 8.3-13.4%) with titers ranging from 50 (50.5%) to 3200 (1.7%). The serological evidence from this study indicated that N. caninum infection is widely distributed among goat-rearing herds in Minas Gerais and further studies are needed in order to evaluate the impact of this parasite as a cause of reproductive disorders.

Using decision analysis to estimate 3-D seismic value-Minas field, Sumatra Indonesia  

SciTech Connect

Decision Analysis has been used to estimate the value added from a 3-D seismic survey recorded over Minas field, Central Sumatra. The method involves comparing the expected values which result from the various decision options, such as acquiring 3-D or not. Probabilities must be assigned to the various branches of the decision tree. These include for example, the expected reliability of the 3-D data as well as the subsequent interpretation. Anticipated drilling results with and without 3-D are assessed after reviewing historical data and interviewing experts to obtain 10th, 50th and 90th percentile results for various scenarios. In this way the expected value, or cumulative distribution of the expected value of the 3-D can be computed and risk can be assessed. The Minas 3-D survey is the largest (450 square kilometers) of over 25 development 3-D surveys recorded by Caltex Pacific Indonesia (CPI) over its fields in Central Sumatra. This survey was conducted after nearly 50 years of production from more than 750 wells. CPI's 3-D experience has shown that increasing the subsurface resolution within complex high angle faulted areas results in new drilling locations in older mature fields such as Minas. Better knowledge of the oil producing reservoirs can also be used to optimize pattern waterflood locations, horizontal drilling and other tertiary recovery studies.

Plant-Derived MINA-05 Inhibits Human Prostate Cancer Proliferation In Vitro and Lymph Node Spread In Vivo1  

PubMed Central

Few treatment options exist for metastatic prostate cancer (PC) that becomes hormone refractory (HRPC). In vitro, plant-derived MINA-05 caused dose-dependent decreases in cell numbers in HRPC cell lines LNCaP-C4-2B and PC-3, and in androgen-sensitive LNCaP-FGC, DuCaP, and LAPC-4, by WST-1 assay. MINA-05 pretreatment significantly decreased clonogenic survival in agar and on plastic at 1 x and 2 x IC50 for PC-3 (P < .05 and P < .001, respectively), and at ½ x, 1 x, and 2 x IC50 for LNCaP-FGC cells (P < .001). MINA-05 also induced G2M arrest of LNCaP-FGC and PC-3 cells (by flow cytometry) and caused some apoptosis in LNCaP-FGC (sub-G1 peak on flow, expression of activated caspase-3) but not in PC-3 cells. Western blotting indicated that these cell cycle changes were associated with decreased levels of regulatory proteins cyclin B1 and cdc25C. MINA-05 given daily by gavage for 39 days did not diminish primary orthotopic PC-3 growth in nude mice, but decreased the extent of lymph node invasion at higher doses. We conclude that MINA-05 induces G2M arrest, inhibits cell growth, reduces PC cell regrowth in vitro, and reduces lymph node invasion after orthotopic PC-3 cell implantation in vivo. It has potential as an adjuvant treatment for patients with PC.

A group of 291 Staphylococcus aureus isolates from mastitic cow's milk (n = 125), bulk tank milk (n = 96), and Minas frescal cheese (n = 70) were screened for staphylococcal enterotoxin (SE) genes (sea, seb, sec, sed, see, seg, seh, sei, selj, and sell) and for the tst-1 gene encoding staphylococcal toxic shock syndrome toxin 1 by PCR assay. A total of 109 (37.5%) of the isolates were positive for at least one of these 11 genes, and 23 distinct genotypes of toxin genes were observed. Of the S. aureus isolates bearing SE genes, 17 (13.6%) were from mastitic cow's milk, 41 (41.7%) were from bulk tank milk, and 51 (72.9%) were from Minas frescal cheese. The occurrence of exclusively more recently described SE genes (seg through sell) was considerably higher (87 of 109 PCR-positive strains) than that of classical SE genes (sea through see, 15 strains). The SE genes most commonly detected were seg and sei; they were found alone or in different combinations with other toxin genes, but in 60.8% of the cases they were codetected. No strain possessed see. The tst-1 gene was found in eight isolates but none from mastitic cow's milk. Macrorestriction analysis of chromosomal DNA from 89 S. aureus isolates positive for SE gene(s) was conducted with the enzyme SmaI. Fifty-five distinct pulsed-field gel electrophoresis patterns were found, demonstrating a lack of predominance of any specific clone. A second enzyme, Apa I, used for some isolates was less discriminating than Sma I. The high genotype diversity of potential toxigenic S. aureus strains found in this study, especially from Minas frescal cheese, suggests various sources of contamination. Efforts from the entire production chain are required to improve consumer safety. PMID:21219740

[Male mortality due to external causes in the State of Minas Gerais, Brazil].  


A descriptive study of a time series seeking to assess mortality due to external causes in males in the State of Minas Gerais was conducted in the period from 1999 to 2008, duly identifying the behavior of this group of causes throughout the time series. Data were obtained about the male population resident in the State of Minas Gerais recorded in the Unified Health System (SUS). Mortality rates per 100,000 inhabitants, divided by age group and specific cause were calculated. A simple linear regression model was used to check the trends of male deaths during the study period. An increase in male mortality in all years of the study period was found, rising from 82.7 deaths per 100,000 in 1999 to 95.7 deaths per 100,000 in 2008, representing a 15.7% increase in the risk of death due to external causes. Young male adults (20-39 years) accounted for the majority of deaths due to external causes. In relation to traffic accidents, there was an increase in mortality rates, especially between 2000 and 2007. The rates of suicide and homicide also rose in the period. In conclusion, it is necessary to adopt preventive measures, since men are prone to death due to external causes, in order to contribute to the inclusion of specific aspects into educational programs geared to reverse this trend.

[Fertility of indigenous women in Minas Gerais State, Brazil: an analysis using the 2000 census].  


Indigenous populations living in villages in Brazil have presented high total fertility rates (TFR) that have increased over time in some cases. Meanwhile, data from the Brazilian Institute of Geography and Statistics (IBGE) or National Census Bureau show a decline in the TFR for the total self-declared indigenous population (combining urban, rural, and specific rural residence). The current study uses data from the 2000 Population Census to describe and compare the structure and level of period fertility for the cohort of self-declared indigenous women living in the State of Minas Gerais. We calculated age-specific fertility rates (ASFR), the period TFR for 2000, and the cohort TFR for women 50 years and older. According to the findings, self-declared indigenous women living in Minas Gerais experienced high fertility in the past, regardless of their place of residence. In conclusion, the 2000 Population Census is an important data source for studies on indigenous populations in Brazil, based on the high coverage and wealth of information. PMID:19009128

Plant-derived MINA-05 inhibits human prostate cancer proliferation in vitro and lymph node spread in vivo.  


Few treatment options exist for metastatic prostate cancer (PC) that becomes hormone refractory (HRPC). In vitro, plant-derived MINA-05 caused dose-dependent decreases in cell numbers in HRPC cell lines LNCaP-C4-2B and PC-3, and in androgen-sensitive LNCaP-FGC, DuCaP, and LAPC-4, by WST-1 assay. MINA-05 pretreatment significantly decreased clonogenic survival in agar and on plastic at 1 x and 2 x IC50 for PC-3 (P < .05 and P < .001, respectively), and at 1/2 x, 1 x, and 2 x IC50 for LNCaP-FGC cells (P < .001). MINA-05 also induced G2M arrest of LNCaP-FGC and PC-3 cells (by flow cytometry) and caused some apoptosis in LNCaP-FGC (sub-G1 peak on flow, expression of activated caspase-3) but not in PC-3 cells. Western blotting indicated that these cell cycle changes were associated with decreased levels of regulatory proteins cyclin B1 and cdc25C. MINA-05 given daily by gavage for 39 days did not diminish primary orthotopic PC-3 growth in nude mice, but decreased the extent of lymph node invasion at higher doses. We conclude that MINA-05 induces G2M arrest, inhibits cell growth, reduces PC cell regrowth in vitro, and reduces lymph node invasion after orthotopic PC-3 cell implantation in vivo. It has potential as an adjuvant treatment for patients with PC. PMID:17460776

Mature field development using 3-D seismic in Minas field, Central Sumatra, Basin, Indonesia  

SciTech Connect

The Minas field 3-D seismic survey (450 km2) was conducted after nearly 4000 MMBO of production. Interpretation of the data has shown a significant number of remaining prospects within the field. Delineation of these locations was impossible using the 2D seismic grid. The new 3D data cube has revealed locations in simple anticlines, en-echelon folds, faulted monoclines, rollover folding, complex faulted zones, stratigraphic traps and within a fractured basement high. The new interpretation has identified more than 75 development and OSWC well locations. These wells will produce an estimated 75 MMBO. As the result of a $5MM seismic survey, the asset value will increase by nearly $1000MM.

Quantification of vertical transmission of Neospora caninum in dairy cows in Minas Gerais, Brazil.  


The objective of this cross-sectional study was to estimate the rate of vertical transmission and to investigate horizontal transmission of Neospora caninum and occurrences of reproductive abnormalities in seropositive dairy cows on two farms in the state of Minas Gerais, Brazil. The frequency of cows seropositive for N.caninum according to the indirect fluorescent antibody test (IFAT) was 39.4% (93/236) for Farm A and 31.4% (32/102) for the Farm B (p > 0.05). The mean vertical transmission rates for N. caninum were 29% and 9% for the herds of Farms A and B, respectively. No negative effects (p > 0.05) from infection by N.caninum were observed regarding milk production and occurrences of reproductive abnormalities in herds A and B. PMID:23070443

Sandflies (Diptera: Psychodidae) from caves of the quartzite Espinhaço Range, Minas Gerais, Brazil.  


This study investigated the sandfly fauna of two quartzite caves in the Espinhaço Mountain Range, located in the municipality of Diamantina, state Minas Gerais. From August 2010-July 2011, entomological sampling was performed in the caves of Salitre and Monte Cristo with two HP light traps exposed in the photic and aphotic zones of each cave. The sandfly fauna consisted of 17 species, among which Lutzomyia cipoensis was predominant (54.76%). The male/female ratio in the total captures was 1:2.5. The aphotic zone showed the highest frequency of specimens captured (65%). A greater density of sandflies occurred during the summer (January-February), coinciding with the period of higher temperatures, humidity and rainfall. The presence of Lutzomyia longipalpis, Lutzomyia whitmani and Lutzomyia pessoai, proven or suspected vectors of leishmaniasis, is of concern because the area is visited by many tourists.

Use of Indicator Kriging to Investigate Schistosomiasis in Minas Gerais State, Brazil  

PubMed Central

Geographic Information Systems (GISs) are composed of useful tools to map and to model the spatial distribution of events that have geographic importance as schistosomiasis. This paper is a review of the use the indicator kriging, implemented on the Georeferenced Information Processing System (SPRING) to make inferences about the prevalence of schistosomiasis and the presence of the species of Biomphalaria, intermediate hosts of Schistosoma mansoni, in areas without this information, in the Minas Gerais State, Brazil. The results were two maps. The first one was a map of Biomphalaria species, and the second was a new map of estimated prevalence of schistosomiasis. The obtained results showed that the indicator kriging can be used to better allocate resources for study and control of schistosomiasis in areas with transmission or the possibility of disease transmission.

[Musculoskeletal disorders among healthcare workers in Belo Horizonte, Minas Gerais State, Brazil].  


This cross-sectional study investigated the prevalence of musculoskeletal disorders and associated factors in a sample of 1,808 workers (from a total of 13,602) in the municipal health system in Belo Horizonte, Minas Gerais State, Brazil. Prevalence was calculated according to self-reported pain in the upper or lower limbs and/or back, and size of associations was estimated by univariate (p ? 0.20) and multivariate Poisson regression (p ? 0.05). Musculoskeletal disorders showed a prevalence of 49.9% and were statistically associated with female gender, living with a partner, physical activity less than twice a week, self-reported common mental disorder, certain job positions (dentists, dental technicians, and community health workers), high physical demand, and inadequate working conditions. The results confirm the complexity of musculoskeletal disorders and suggest areas for development of health promotion programs in health services. PMID:22892976

Mercury fractionation in stream sediments from the Quadrilátero Ferrífero gold mining region, Minas Gerais State, Brazil.  


The Iron Quadrangle (IQ) region, located in the state of Minas Gerais, has been the most important gold producing area in Brazil since the end of seventeenth century. The use of mercury for gold amalgamation in small scale mines has been responsible for large release of Hg to aquatic and terrestrial environments during 300 years of mining. The present work sought to evaluate the fractionation of Hg in stream sediments is the southern region of the IQ by utilizing sequential extraction. Since mobility and availability of Hg are related to its distribution among sediment partitions, fractionation methods provide detailed information on the ecotoxicological impact and risks associated to the presence of Hg in sediments. The total Hg concentration varied from 179.3 to 690.1 microg kg( - 1) and Hg(0) accounted for the majority at all sample sites, ranging from 42% to 56% of the total. PMID:18821025

Hematite mining in the ancient Americas: Mina Primavera, A 2,000 year old Peruvian mine  

NASA Astrophysics Data System (ADS)

Mina Primavera, a hematite (Fe2O3) mine located in southern Peru, was exploited beginning approximately 2,000 years ago by two Andean civilizations, the Nasca and Wari. Despite the importance of hematite in the material culture of the ancient Americas, few hematite mines have been reported in the New World literature and none have been reported for the Central Andes. An estimated 3,710 tonnes of hematite were extracted from the mine for over 1,400 years at an average rate of 2.65 tonnes per year, suggesting regular and extensive mining prior to Spanish conquest. The hematite was likely used as a pigment for painting pottery, and the mine demonstrates that iron ores were extracted extensively at an early date in the Americas.

Improving patient access to specialized health care: the Telehealth Network of Minas Gerais, Brazil  

PubMed Central

Abstract Problem The Brazilian population lacks equitable access to specialized health care and diagnostic tests, especially in remote municipalities, where health professionals often feel isolated and staff turnover is high. Telehealth has the potential to improve patients’ access to specialized health care, but little is known about it in terms of cost-effectiveness, access to services or user satisfaction. Approach In 2005, the State Government of Minas Gerais, Brazil, funded the establishment of the Telehealth Network, intended to connect university hospitals with the state’s remote municipal health departments; support professionals in providing tele-assistance; and perform tele-electrocardiography and teleconsultations. The network uses low-cost equipment and has employed various strategies to overcome the barriers to telehealth use. Local setting The Telehealth Network connects specialists in state university hospitals with primary health-care professionals in 608 municipalities of the large state of Minas Gerais, many of them in remote areas. Relevant changes From June 2006 to October 2011, 782 773 electrocardiograms and 30 883 teleconsultations were performed through the network, and 6000 health professionals were trained in its use. Most of these professionals (97%) were satisfied with the system, which was cost-effective, economically viable and averted 81% of potential case referrals to distant centres. Lessons learnt To succeed, a telehealth service must be part of a collaborative network, meet the real needs of local health professionals, use simple technology and have at least some face-to-face components. If applied to health problems for which care is in high demand, this type of service can be economically viable and can help to improve patient access to specialized health care.

Seroprevalence and risk factors for Neospora caninum in sheep in the state Minas Gerais, southeastern Brazil.  


The aim of this study was to determine the prevalence and risk factors associated with infection due to Neospora caninum in serum samples from 488 sheep originating from 63 farms in 63 municipalities distributed across eight of the twelve mesoregions of the state Minas Gerais, southeastern Brazil. For detection of N. caninum the sheep serum samples were subjected to the indirect fluorescence antibody test (IFAT ? 50). To identify the risk factors associated with infection due to N. caninum a questionnaire was filled out for each herd by interviewing, the individual responsible for the herd, demanding information on the general characteristics of the property. Sixty-four sheep sera (13.1%; 95% CI=10.3-16.4) presented IgG-specific anti-N. caninum antibodies with the following titers: 50 (49; 76.6%), 100 (7; 10.9%), 200 (4; 6.2%), 400 (3; 4.7%) and 800 (1; 1.6%). The prevalence of infected sheep per mesoregion ranged from 0 to 28.1%. Out of the 63 farms sampled, 31 (49.2%; 95% CI=36.4-62.1) presented at least one seropositive sheep. No significant association was found between the presence of anti-N. caninum antibodies and the risk factors evaluated on the farms, except for the mesoregion variable (p=0.004; OR=0.429; CI95%=0.182-1.008). These results indicate that there is a need for additional research to define the epidemiological importance of this parasite as a cause of reproductive problems in sheep herds in Minas Gerais.

[The creation of hospitals by charities in Minas Gerais (Brazil) from 18th to 20th century].  


This article is the fruit of research into the cultural heritage of healthcare in Minas Gerais (Brazil) and explores the construction of hospitals supported by Catholic charities from the 18th to 20th century. Catholicism has always been strong in Minas Gerais, partly because the Portuguese Crown prohibited the free travel of priests, who were suspected of illegally trading in gold from the mines. A brotherhood was responsible for creating the first Santa Casa, in Vila Rica. Another very important religious group in Brazil, the Vincentians, was also devoted to charitable works and propagated the ideas on charity of Frederico Ozanan, based on the work of St. Vincent de Paul. This group comprised both a lay movement, supported by conferences organized by the St. Vincent de Paul Society, and a religious order, the Vincentian priests and nuns. Catholic physicians make up the third group studied here, organized in a professional association promoted by the Catholic Church. The brotherhoods, Vincentians, and associations, with their Santa Casas, represent a movement that is recognized worldwide. The enormous Catholic participation in these charitable works brought in the physicians, who would often make no charge and exerted efforts to create hospitals that served the population. Although the capital of Minas Gerais was the creation of republicans and positivists in the 20th century, with their ideas of modernity, it remained dependent on Christian charity for the treatment of the poor.

Management practices to control gastrointestinal parasites in dairy and beef goats in Minas Gerais; Brazil.  


Parasitic infection is recognized worldwide as a limiting factor in the production of goats, and various control methods are used to reduce economic losses, often without considering the epidemiology of the parasites. This has led to the development of highly tolerant parasite populations and the presence of chemical residues in the beef and milk. The objective of this study was to determine the level of knowledge of goat farmers about parasitic diseases and to correlate this with the epidemiology of endoparasites and parasite control practices in goat farms in the state of Minas Gerais, Brazil. The analysis was based on a questionnaire applied by trained veterinarians. The sample was homogeneous throughout the state, covering 18.4% (157/853) of municipalities. Eighty-four dairy goat farms in 81 municipalities and 200 properties with beef goats in 76 municipalities were evaluated. The herd size per goat farm ranged from 4 to 57 (average 24) for beef herds and from 2 to 308 (average 63) for dairy farms. The majority of the beef herd production was extensive and semi-extensive (98.5%), while the dairy herds were maintained under intensive farming (98.8%). The mixed production of goats and sheep was reported by 36.5% of beef goat farmers and by 20.2% of dairy goat farmers. Among the beef goats farms on which the technological level was determined, 2.0% were categorized as having high technological level, 34.5% as medium, and 63.5% as low. Of the 84 dairy farms, 30% operated at a high, 47% at a medium, and 23% at a low technological level. The adoption of practices to reduce parasitism, such as the quarantine of animals, treatment of newly arrived animals, regular cleaning of the floor, and technical assistance, was significantly higher on dairy farms than on beef farms. Although 85.7% of dairy farmers and 83% of beef farmers medicate their animals, the treatments were performed without technical criteria, and deworming intervals ranged from 30 to 120 days or more. The average interval between treatments was significantly longer in dairy goat herds (4.8 months) than in the beef herds (3.6 months). The most commonly used drugs were macrocyclic lactones (37.7% in dairy and 39.5% in beef herds) and benzimidazoles (48.9% in dairy and 31.5% in beef herds). Goat production in Minas Gerais is still in its infancy, and even though using a control program associated with other health practices, producers still rely heavily on chemicals to get satisfactory results.

Paleomagnetic Evaluation of Crustal-Scale Block Rotations in the Mina Deflection of the Central Walker Lane  

NASA Astrophysics Data System (ADS)

Crustal deformation resulting from relative Pacific-North America plate motion is broadly distributed on faults across the western U.S.. Geodetic observations show that some 25 percent of transform plate motion is currently accommodated by faults east of the Sierra Nevada, from the eastern California shear zone to the central Walker Lane (CWL). The northwest trending faults of the CWL are joined to the Furnace Creek - Owens Valley fault system by the Mina deflection, a belt of east-northeast striking faults that serve as a displacement transfer system linking the two fault zones. The Furnace Creek - Owens Valley fault system has a cumulative right-slip of 40 - 50 km, and this displacement is transferred in an extensional right-step to the curved high-angle faults of the Mina deflection. The high-angle fault geometry and basin depths preclude more than 10 km of right-lateral displacement accommodated along structures in the Mina deflection and thus a slip deficit of 30 to 40 km exists. We are attempting to resolve the amount of permanent Neogene strain in the Mina deflection and determine if the geodetically observed strain accumulation and local heterogeneities are consistent with the permanent Neogene strain, in particular, vertical axis rotation of blocks in the Mina deflection area. To in part quantify the magnitude and potential heterogeneities of crustal block rotation and to more clearly define block boundaries, paleomagnetic data have been obtained from numerous stratigraphic sections of upper Tertiary volcanic rocks in a 300 sqkm area centered on the Candeleria Hills, NV. Eight to ten oriented samples from 260 sites distributed across multiple tectonic blocks have been fully demagnetized with all sites yielding interpretable results (23 sites (two sections) in mid Miocene andesite flows, 102 sites (10 sections) in upper Miocene basalt flows, and 135 sites (27 sections) in lower Miocene, regionally extensive ash flow tuffs). Although some anomalous directions were observed, the stratigraphically corrected (typically less than 15° dip) data from the volcanic rocks are internally consistent, well-grouped at the site level, and discordant clockwise to late Cenozoic expected field direction (358\\deg, 58\\deg). For example, a Miocene basalt flow section in the central Candelaria Hills yields a group mean (D = 16.5, I = 50.0, a95 = 1.8, k = 497.3) that provides an inferred rotation of +18.5\\deg +/- 6.9\\deg compared to a late Cenozoic expected field. Two sites in the Candelaria Junction regional ash flow tuff located in separate structural blocks yield similar inclinations, yet statistically distinct declinations (Site1, 255.8, -48.6, 4.4; Site2, 296.4, -41.0, 4.6), providing evidence for a modest clockwise vertical axis rotation between structural blocks. Overall, we interpret most data obtained to reflect at most moderate clockwise vertical axis rotation among structural blocks in the Mina deflection region. The absence of large magnitude rotation of any individual block and, thus between blocks, places limits on the amount of cumulative slip on fault networks in the Mina deflection. The area may be accommodating strain by net northwest extension on a curved fault array with very low rates of vertical axis rotation and minor slip on individual faults. To compare the geodetic observations with long-term strain, we are developing a tectonic model, using existing fault geometries and paleomagnetic data for the CWL that links vertical axis rotations of the fragmented upper crust to the driving mechanisms associated with slip transfer across the region.

Horizontal well application in a mature field - Minas Field, Sumatra, Indonesia  

SciTech Connect

Minas Field, the largest oil field in Southeast Asia, is located in Central Sumatra, Indonesia. The 400 square kilometer field was discovered in December, 1944 and placed on production in February, 1951. Nearly 4,000 MMBO of the original 9,000 MMBO in place have been produced. An active development drilling campaign continues and, to date, more than 850 wells have been drilled. Horizontal well technology has been implemented as a strategic portion of the current development plan. The primary objectives of the horizontal wells are to reduce water coning problems, drain unswept oil and minimize environmental impact. A pilot program, initiated in 1994, resulted in three successful horizontal wells. Production rates from these wells were significantly higher than adjacent straight wells. Consequently, a large-scale, horizontal well program is being implemented utilizing short radius and medium radius drilling techniques. The successful execution of this program requires a detailed screening process involving a cross-functional, multi-disciplinary team of geologists and engineers.

Hematite from a mining area in the east border of Quadrilátero Ferrífero, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Iron oxides are dominant minerals in many geo-domains of economical interest, as iron ore mines. Knowing the main mineral transformation pathways is a fundamental step to plan prospecting new mineral deposits. This study aimed at contributing to a better understanding of the chemical and mineralogical processes related to the genesis and transformations of iron oxides involving hematite in an iron-ore mine of the east border of Quadrilátero Ferrífero, Minas Gerais, Brazil. Two representative geo-samples were analyzed with synchrotron radiation X-ray diffraction (XRD), 57Fe Mössbauer spectroscopy, X-ray fluorescence and saturation magnetization ( ?) measurements. The iron content varied from 65 to 69 mass% Fe. From XRD data, hematite is indeed the major mineral for all samples but characteristic reflections of goethite and magnetite also appear. For the magnetic sample, ? = 6.9 J T - 1 kg - 1. 298 K- and 110 K-Mössbauer data allow characterizing hematite in these iron-rich geo-materials.

[Association between air pollution and respiratory and cardiovascular diseases in Itabira, Minas Gerais State, Brazil].  


The city of Itabira, Minas Gerais State, Brazil, is located in the Espinhaço Mountain Range, an area that features large-scale mechanized iron ore pit mines. The current study evaluates the acute effects of inhalable particulate matter (PM10) in terms of emergency room visits due to respiratory and cardiovascular diseases in Itabira. Generalized additive Poisson regression models were adopted, controlling for temperature, humidity, and both short and long-term seasonality. Increases of 10mg/m(3) in PM10 were associated with increases in respiratory emergency room visits of 4% (95%CI: 2.2-5.8), at lags 0 and 1 for children and adolescents younger than 13 years of age, and of 12% (95%CI: 8.5-15.5) on the three subsequent days for adolescents (13 to 19 years of age). For cardiovascular diseases, the effect was acute (4%; 95%CI: 0.8-8.5) and mainly for the 45 to 64 age group. These results show that PM10 generated by open pit mining can lead to health problems in the exposed population. PMID:18038038

Congenital neosporosis in goats from the State of Minas Gerais, Brazil.  


Congenital Neospora caninum infection was diagnosed in two Saanen goat kids from two distinct herds with a history of abortion and weak newborn goat kids in the Southern region of the State of Minas Gerais, Brazil. The first kid was weak at birth, had difficulty to rise and was unable to nurse. Gross lesions of porencephaly and hydrocephalus ex vacuo were seen. Multifocal necrosis, gliosis and non-supurative encephalitis were observed in the brain. Several parasitic cysts with a thick wall that reacted strongly only with polyclonal antiserum to Neospora caninum were seen in the cerebral cortex, brain stem and cerebellum. The second kid was born from a Neospora caninum seropositive mother that aborted in the last pregnancy. It was born without clinical signs. The diagnosis of neosporosis was based on antibody titer of 1:800 to N. caninum by indirect fluorescence antibody test obtained from blood collected before the goat kid ingested the colostrum and Neospora caninum DNA was detected by polymerase chain reaction and sequenced from placenta. This is the first report of neosporosis in goats in the southeast region of Brazil. PMID:22451736

Perceptions of milk producers from Divinópolis, Minas Gerais, regarding Rhipicephalus (Boophilus) microplus control.  


Semi-systematized interviews were conducted with 100 dairy cattle producers in the municipality of Divinópolis, Minas Gerais, with the aim of ascertaining their perceptions regarding the importance of Rhipicephalus (Boophilus) microplus and of combating it. Content analysis was performed and the frequency distribution of each of the variables was used to construct profiles of the producers interviewed. The production losses caused by ticks were perceived incompletely by the producers, who were unaware of the pathogen transmission caused by the parasite and the indirect losses through combating it, such as the cost of acaricide and labor. The combat operations were performed in a traditional manner, with an excessive number of inefficient treatments that aimed to control the level of infestation at that moment. The quality of the acaricide dipping/spraying applied was affected by the quality of the equipment used to apply the products, lack of knowledge of the mode of action of these products, lack of the specific information needed and lack of motivation caused by unawareness of the disadvantages of chemical combat. It was concluded that the lack of knowledge about combat methods and the acceptance of endemicity of the parasitosis were impediments to changing the realities encountered. PMID:22166383

Perceptions about the biology of Rhipicephalus (Boophilus) microplus among milk producers in Divinópolis, Minas Gerais.  


One hundred semi-systematized interviews were applied with the aim of surveying the perceptions of milk producers in the municipality of Divinópolis, Minas Gerais regarding the biology of the tick Rhipicephalus (Boophilus) microplus. Content analysis was conducted on each of the variables surveyed and their descriptions, highlighting the higher frequencies in order to construct profiles of perceptions about each of the matters surveyed. In addition, each of the producers was categorized regarding their readiness to proceed with efficient control, from the assessment of their responses. Among the variables surveyed were the tick lifespan, duration of parasitic life, time of greatest incidence, survival in pastures and egg-laying volume. These questions are considered important for defining the knowledge needed for rational combat. It was concluded that the information needed for adopting effective practices to combat ticks was insufficient among the milk farm properties in Divinópolis. Moreover, the producers interviewed had a good perception of what they observed in their daily routine, but did not have complementary information about the tick life cycle. PMID:22166382

[Evaluating the implementation of Information System on Live Births in municipalities of Minas Gerais, Brazil].  


This study evaluated the degree of implementation of the Information System on Live Births (SINASC) and its relationship to the organizational context in municipalities (counties) of Minas Gerais State, Brazil, in 2010. The sample included 132 municipalities that had healthcare facilities providing childbirth care and the decentralized SINASC. Data collection used a semi-structured questionnaire. Degree of implementation was defined by a scoring system with different weights for each indicator, according to the respective levels of importance assigned to them, using the following classification: adequate, inadequate, and critical. Data analysis used the median as the summary measure and the Pearson chi-square test for comparison of proportions. SINASC is not adequately implemented in the majority of the municipalities in the sample. Population size and quality of the municipal administration did not influence the degree of implementation. In terms of organization of information in the SINASC, the structure was evaluated as better than the process. Limitations included lack of qualified staff, unsatisfactory collection and completion of certificates of live birth, underutilization of data, and limited publication of the information.

Genotyping of Cryptococcus neoformans isolated from captive birds in Uberaba, Minas Gerais, Brazil.  


To evaluate Cryptococcus spp. molecular types isolated from captive birds' droppings, an epidemiological survey was carried out in Uberaba, Minas Gerais, Brazil, from December 2006 to September 2008. A total of 253 samples of bird excreta (120 fresh and 133 dry) were collected from pet shop cages and houses in different neighbourhoods. Cryptococcus neoformans was isolated in 19 (14.28%) dry samples and one fresh sample (0.84%). Cryptococcus laurentii was recovered from seven (5.26%) dry samples, but not in the fresh samples. The canavanine-glycine-bromothymol blue test was positive in all but one of the C. laurentii isolates. Cryptococcus neoformans molecular typing was performed using URA5-RFLP and the mating type locus using mating type specific PCR. Nineteen (95.0%) presented genotype VNI and one VNII (5.0%). In addition, all isolates presented mating type ?. Thus, the genotype of the environmental C. neoformans isolates observed in this study is in accordance with others already reported around the world and adds information about its distribution in Brazil. Cryptococcus laurentii strains were typed using URA5-RFLP and M13 fingerprinting, which showed similar profiles among them. Thus, despite the low number of C. laurentii isolates analysed, their molecular profile is different from another already reported. PMID:20492533

[Prevalence of intestinal parasites in the Maxakali indigenous community in Minas Gerais, Brazil, 2009].  


A prevalence survey using the TF-Test technique to identify intestinal parasites was conducted in the Maxakali indigenous villages in Minas Gerais State, Brazil. Stool samples were collected on three alternating days, in separate tubes, containing 10% formalin, and unified in a laboratory by double filtering centrifugation. Samples of sediment aliquot were prepared in triplicate and examined by microscope (10x and 40x) for eggs, cysts, and larvae. Prevalence of parasites (89.5%) and polyparasitism (46%) were similar by sex and age, but varied by village. Prevalent species were: Entamoeba histolytica/Entamoeba dispar (48.9%), Giardia duodenalis (32%), Entamoeba coli (40.8%), Endolimax nana (10.3%), hookworms (37.9%), Schistosoma mansoni (23.7%), Hymenolepis nana (18.6%), Strongyloides stercoralis (5.4%), Ascaris lumbricoides (4.9%), and Trichuris trichiura (0.5%). The Maxakali population lives in socially vulnerable conditions, and government agencies need to introduce measures to improve sanitation infrastructure and health education. PMID:23568298

Ticks (Acari: Ixodidae) within various phytophysiognomies of a Cerrado reserve in Uberlândia, Minas Gerais, Brazil.  


Cerrado biome, the South American savannah, covers about 2 million km(2) and is very rich in endemic species but threatened by agriculture. In this report free-living tick species are presented, and their seasonal and relative distribution within the various phytophysiognomies in a small Cerrado reserve in Minas Gerais State, Brazil. Overall 2,694 free-living ticks were found during a 2 years sampling period with CO(2) traps and cloth dragging. Of these, 73.5% were Amblyomma cajennense and 0.6% Amblyomma dubitatum. All other ticks (25.9%) were retained as Amblyomma spp. Adults of A. cajennense peaked in spring, the nymphs in winter of both years. Amblyomma larval clusters were found in autumn and winter. Adult ticks (46.7%) and nymphs (39.5%) were most often found in woodlands, whereas most larval clusters were found in valley-side marshes (39%). Amblyomma cajennense, Anocentor nitens, Rhipicephalus (Boophilus) microplusand Rhipicephalus sanguineus ticks were found on domestic animals from neighboring properties. Search for Rickettsia in the hemolymph of 497 A. cajennense and one A. dubitatum ticks yielded negative results. Results confirmed earlier reports on the overwhelming prevalence of A. cajennense ticks in the Cerrado biome of Brazil and added information to habitat preferences of this tick species, a major vector in Brazil of the Rocky Mountain spotted fever.

Inhibition of Listeria monocytogenes in minas frescal cheese by free and nanovesicle-encapsulated nisin  

PubMed Central

The effectiveness of free and nanovesicle-encapsulated nisin to control Listeria monocytogenes in Minas Frescal cheese was investigated. Commercial nisin was encapsulated into liposomes of partially purified soy lecithin. Free (0.1 mg/mL and 0.25 mg/mL) and nanovesicle-encapsulated nisin (0.25 mg/mL) were applied onto the surface of cheese samples, and L. monocytogenes was inoculated before incubation at 6–8°C for 28 days. A bactericidal effect was observed with 0.25 mg/mL free nisin; a bacteriostatic effect was observed for liposome-encapsulated nisin and 0.1 mg/mL free nisin. Free nisin was more efficient than nisin-loaded liposomes in controlling L. monocytogenes. Possible reasons for this behavior, and also the significance of nisin to soft cheeses are discussed. Nisin acted as a suitable barrier within hurdle technology, potentially extending the shelf-life and safety of fresh cheeses.

Modelling welded material for ultrasonic testing using MINA: Theory and applications  

NASA Astrophysics Data System (ADS)

Austenitic steel multi-pass welds exhibit a heterogeneous and anisotropic structure that causes difficulties in the ultrasonic testing. Increasing the material knowledge is a long term research field for LCND laboratory and EDF Les Renardières in France. A specific model has been developed: the MINA model (Modelling an Isotropy from Notebook of Arc welding). Welded material is described in 2D for flat position arc welding with shielded electrode (SMAW) at a functional scale for UT modeling. The grain growth is the result of three physical phenomena: epitaxial growth, influence of temperature gradient, and competition between the grains. The model uses phenomenological rules to combine these three phenomena. A limited number of parameters is used to make the modelling possible from the information written down in a notebook of arc welding. We present all these principles with 10 years' hindsight. To illustrate the model's use, we present conclusions obtained with two recent applications. In conclusion we give also insights on other research topics around this model : inverse problem using a F.E.M. code simulating the ultrasonic propagation, in position welding, 3D prospects, GTAW.

Congenital Neosporosis in Goats from the State of Minas Gerais, Brazil  

PubMed Central

Congenital Neospora caninum infection was diagnosed in two Saanen goat kids from two distinct herds with a history of abortion and weak newborn goat kids in the Southern region of the State of Minas Gerais, Brazil. The first kid was weak at birth, had difficulty to rise and was unable to nurse. Gross lesions of porencephaly and hydrocephalus ex vacuo were seen. Multifocal necrosis, gliosis and non-supurative encephalitis were observed in the brain. Several parasitic cysts with a thick wall that reacted strongly only with polyclonal antiserum to Neospora caninum were seen in the cerebral cortex, brain stem and cerebellum. The second kid was born from a Neospora caninum seropositive mother that aborted in the last pregnancy. It was born without clinical signs. The diagnosis of neosporosis was based on antibody titer of 1:800 to N. caninum by indirect fluorescence antibody test obtained from blood collected before the goat kid ingested the colostrum and Neospora caninum DNA was detected by polymerase chain reaction and sequenced from placenta. This is the first report of neosporosis in goats in the southeast region of Brazil.

Genetic diversity of Annona crassiflora (Annonaceae) in northern Minas Gerais State.  


Genetic diversity analyses of tropical tree species are relevant to landscape management, plant genetic resource inventory, and biological conservation of threatened species. Annona crassiflora is an endangered fruit tree native to the Cerrado biome that is threatened by reduction of natural populations and fruit extraction. We examined the intra- and interpopulational genetic diversity of this species in the northern region of Minas Gerais State. Seventy-two individuals from four natural populations were genotyped using RAPD markers. We found moderate genetic diversity among populations, with Shannon's I index varying between 0.31 and 0.44, and Nei's genetic diversity (H(E)) for the population set equal to 0.31. AMOVA indicated a greater genetic variation within (77.38%) rather than among populations (22.62%), tending towards isolation by distance (Mantel's r = 0.914; P = 0.089). Nei's genetic identity estimates among populations revealed a hierarchical pattern of genetic similarity of form [(CA1, CA2), MC], [(GM)], corroborating the high genetic differentiation between spatially isolated populations.

[Talc pneumoconiosis among soapstone handicraft workers in a rural area of Ouro Preto, Minas Gerais, Brazil].  


Talc pneumoconiosis in Brazil has received little research attention to date. The disease was investigated in Mata dos Palmitos, a district of Ouro Preto, Minas Gerais State, among soapstone handicraft workers. The district has some 180 inhabitants, of whom 108 are engaged in handicrafts production, while 15 alternate handicrafts production with work in the soapstone quarries. A clinical and occupational investigation was conducted, along with a respiratory symptoms standardized questionnaire, chest x-ray (ILO standard), and spirometry. Clinical data showed a low prevalence of respiratory complaints. Dyspnea was the most frequent symptom. Chronic bronchitis was identified in 12 adult workers. Chest x-rays showed evidence of small lung opacities in 5 workers, and in 11 there was suspicion of the same opacities. One worker showed a plaque-shaped pleural thickening. Seven workers showed abnormal spirometry. The soapstone dust composition showed breathable asbestos fibers from the amphibole group (tremolite-actinolite). The results suggest talc asbestosis occurrence among soapstone handicraft workers. PMID:14999341

Perceptions and attitudes among milk producers in Minas Gerais regarding cattle tick biology and control.  


This study evaluates milk producers' knowledge regarding cattle ticks and practices for controlling them. Ninety-three dairymen in Minas Gerais were interviewed. These producers had no information regarding acaricide efficiency tests. To analyze the information, open responses were categorized through "content analysis", and descriptive analysis consisting of extracting the profile highlighted by the highest frequencies. The association between schooling level and knowledge was tested by means of chi-square trend tests. It was observed that 92.3% had no knowledge of the nonparasitic period. For 96.4%, what determined the time to apply treatment was the degree of tick infestation; 93.3% used spray guns to apply the acaricide. In seeking to cross-correlate the biological and control variables with education, cooperative action, length of experience and herd size, it was found that there was a linear association between schooling level and implementation of acaricide solution preparation. The other factors didn't show any significant association. These data demonstrated the need to instruct the producers in relation to the biology and control of Rhipicephalus (Boophilus) microplus. It was concluded that the majority of milk producers were unaware of cattle tick biology and the factors that influence choosing an acaricide, which makes it difficult to implement strategic control.

Geology of the Gualan and Southern Sierra de las Minas Quadrangles, Guatemala  

NASA Astrophysics Data System (ADS)

The Gualan and Sierra de las Minas quadrangles straddle the Motagua Valley fault zone, a major southerly convex fault zone of Nuclear Central America, and the active transform boundary between the North American and Caribbean plates. Two distinctly different pre-Mesozoic metamorphic basement complexes are exposed in the area. The Chuacus Group crops out north of the Motagua Valley. The Las Ovejas Complex crops out south of the valley. Early Tertiary rift basins received clastic deposits of the Subinal Formation. Concurrently, hornblende diorite and La Union pluton granodiorites intruded the Las Ovejas. Sinistral strike slip motion began in the Miocene and the Junquillo pull apart basin formed between the Cabanas and Jubuco faults along the south side of the valley. Las Ovejas Complex rocks between these faults were mylonitized during the faulting. Southerly derived Plio-Quaternary alluvial fans in the Junquillo basin have been offset left laterally as much as 15 to 20 km from their source areas by the Jubuco fault. A shift in the active trace of the Jubuco fault led to uplift of the western Junquillo basin during the Quaternary. The Cabanas fault is now the active plate boundary.

[Mortality Information System in small municipalities of Minas Gerais state: concepts of health professionals].  


Strategies to accelerate the consolidation process of health information systems and make it possible to obtain reliable data on vital statistics are urgently needed. This qualitative study sought to understand the concepts of municipal administrators and Epidemiology managers about the Mortality Information System (MIS) in the Northeast region of Minas Gerais, one of the poorest in the state with the highest proportions of deaths with ill-defined causes. Professionals from ten municipalities were interviewed and their answers evaluated by content analysis. It was found that the MIS was perceived as important for management, but there was a general perception among respondents that it served the state and federal managers rather than the municipality in the planning of health actions. Improvements were reported in the physical structure of the municipalities to make the MIS operational, but also shortcomings related to lack of trained human resources for the systematic use and production of data at the local level and with high staff turnover. Partnerships between the health department with other state sectors can contribute to reduce under-registration of events and deaths with ill-defined causes. PMID:23670476

[Drinking-and-driving prevalence in Belo Horizonte, Minas Gerais State, Brazil].  


Problems resulting from alcohol consumption by drivers have been studied worldwide, and epidemiological research points to high injury and death rates related to drinking-and-driving. However, equivalent data are limited in Brazil. In this study, 913 drivers were stopped on public roads with heavy traffic and high concentrations of bars, restaurants, and nightclubs in Belo Horizonte, Minas Gerais State, and asked to answer a questionnaire and submit to an active breathalyzer test. The study was done in December 2005 and December 2006. The study adopted the internationally accepted sobriety checkpoint method. In the sample, 38.0% of drivers showed some trace of alcohol in their exhaled air, and 19.6% were at or above the legal limit (0.6 g/l). These figures were five times those found in similar surveys in other countries. The findings suggest a critical drinking-and-driving problem in Belo Horizonte (and probably elsewhere in Brazil) and the need for on-going research, the development of specific public policies to deal with the problem, and effective enforcement of the existing law.

Iron oxides of Fazendão Deposit, East Border of Quadrilátero Ferrífero, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The iron oxides highly influence the soil structure and aggregation of mineral particles in soil. They also play an important role in some economical variables, as those related to the use of land for agriculture practices or mineral exploitation, in ore mining activities. About 60 % of all industrial activities on iron processing in Brazil is based on ores mined in the geodomain of Quadrilátero Ferrífero, state of Minas Gerais, Brazil. Samples of a mining area for iron, the Fazendão Deposit in the east border of Quadrilátero Ferrífero have been studied in an attempt to contribute to a better understanding of the key chemical and mineralogical pathways related to the formation and transformation of iron oxides, involving hematite. From powder diffraction patterns, it is confirmed that hematite is the main mineralogical phase in all samples. The total iron contents were found to range between 65.15 and 70.00 mass%. The saturation magnetization values, ? = 6.9 and 2.1 J T-1 kg-1 are significantly measurable only for the two samples showing some evidences of magnetite. 298 K-Mössbauer data confirmed the dominant occurrence of hematite in all samples, along with magnetite for the two samples showing non-zero magnetization. 110 K-Mössbauer data indicate that the hematite in all samples undergoes the Morin transition (TM approx 260 K), as expected for the relatively pure oxide. Maghemite could not be detected in any sample. New numerical analysis are now being performed, using Rietveld refinement of XRD data, in an attempt to obtain crystallographic results that could indicate more reliable evidences about the mechanisms of formation of hematite, particularly in the magnetic samples, for which the precursor is presumably magnetite.

Cervical uterine lesions: an epidemiological and molecular investigation in midwestern Minas Gerais, Brazil.  


Cervical uterine cancer is the second most frequent form of cancer in the female population and the fourth cause of cancer deaths among Brazilian women. In Divinópolis county, Minas Gerais state, cervical cancer accounted for 6.6% of deaths in 2007. The purpose of this study was to conduct an epidemiological and molecular investigation of samples of pre-neoplastic and neoplastic cervical uterine lesions from patients assisted at public healthcare services in the county. The study was based on clinical-epidemiological descriptions retrieved from cytological examination request forms from 2006 to 2010. For molecular analysis, samples from 95 patients were collected and DNA was extracted using the Chelex 100 method. PCR was performed for detection and typing of HPV 6/11, 16, 18, 31, and 33. Of the 52 168 patients who underwent cytological examination, 625 had pre-neoplastic or neoplastic lesions during the study period. Age distribution was consistent with the literature, with a predominance of patients aged 20-49 years. The microorganism found most frequently was Lactobacillus sp. (65%). Prominent among cellular alterations were cervical intraepithelial neoplasia I (39.7%) and atypical squamous cells of undetermined significance (32%). Molecular analysis revealed 72.6% of positive samples for HPV. HPV 16 (26.3%) was the most frequent type, followed by types 6/11 (7.4%), 18 (5.3%), 33 (2.1%), and 31 (1%). The results provided improved understanding of the association between HPV and cancer in Divinópolis, in addition to providing data that can contribute to the design of measures to prevent and control HPV infection in the county investigated.

Diversity of phlebotomine sand flies (Diptera: Psychodidae) in Ibitipoca State Park, Minas Gerais, Brazil.  


Leishmaniasis is a complex of zoonotic diseases that are endemic to many Brazilian states. They are transmitted to the vertebrates by the bite of the hematophagous female sand fly (Diptera: Psychodidae) vectors. Despite the increasing occurrence of visceral and cutaneous leishmaniasis cases in large urban centers, their transmission continues to occur primarily in a wild environment and may be associated with professional activities, ecotourism activities, or both. This study investigates the ecological parameters of the sand flies present in Ibitipoca State Park, Minas Gerais, Brazil. During 2009, systematic collections of sand flies were made monthly using HP light traps installed at five sites, including three natural settings (a cave, riparian vegetation, and a rain forest), the tourist and researchers' accommodations, and a surrounding domestic livestock area. In total, 161 sand flies (seven species) were collected, the most abundant, particularly in the surrounding domestic livestock area, being Lutzomyia (Psychodopygus) lloydi (Antunes, 1937). Furthermore, a previously unidentified Lutzomyia (Sciopemyia) sp. was prevalent in the cave environment. There are no existing records of the occurrence of leishmaniasis in Ibitipoca State Park; however, the some species of the subgenus Psychodopygus are known vectors of Leishmania spp in Brazil. Hence, the presence of a species of this genus in areas surrounding the park may represent a risk to ecotourism and the local inhabitants. Our study shows the importance of regular monitoring of the various areas used by humans to determine the distribution and spread of sand fly vectors for preventive management to forestall potential risk to health and consequent effect on ecotourists.

[The Brazilian School Nutrition Program from the standpoint of students attending state schools in Minas Gerais, Brazil].  


The scope of this article is to analyze the Brazilian School Nutrition Program from the standpoint of students attending state schools in Minas Gerais. It is a qualitative and quantitative cross-sectional study with a sample of 1500 students, representing the population of the state schools of Minas Gerais, involving the administration of a semi-structured questionnaire. The data were analyzed using simple frequency, mean, standard deviation, Fisher's exact test, the chi-square test and logistic regression (p < 0.05, CI 95%). The effective acceptance of the program was 28.8% and the effective adhesion to the program was 45.1%. Program acceptance was significantly higher among males and students who consumed less extra-institutional food. Acceptance and adhesion to the program was significantly higher among the older students and those who reported participating in activities related to nutritional education. In total, 73.5% of the students suggested improvements in school food. Many of the program's norms and guidelines are not being implemented. The acceptance of school food was negatively influenced by the consumption of extra-institutional foods and positively influenced by food and nutritional education activities. PMID:23670372

Hepatic photosensitization in buffaloes intoxicated by Brachiaria decumbens in Minas Gerais state, Brazil.  


The aim of this paper is to report the study of hepatogenous photosensitization in buffaloes during two outbreaks provoked by ingestion of Brachiaria decumbens in Minas Gerais state, Brazil. Ten young buffaloes in outbreak 1 and seven buffaloes in outbreak 2 were intoxicated by B. decumbens. Nine clinically healthy buffaloes raised under the same conditions as the sick animals served as the control group. All animals were subjected to clinical examination, and serum was collected to measure gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST), direct bilirubin (DB), indirect bilirubin (IB) and total bilirubin (TB) as indicators of liver function and urea and creatinine as indicators of renal function. Histopathology of liver fragments from five different animals was carried out. During the outbreaks and every two months for one year, samples of grass from paddocks where the animals got sick were collected for quantitative evaluation of the saponin protodioscin, combined with observations of pasture characteristics and daily rainfall. Clinical signs included apathy, weight loss, restlessness, scar retraction of the ears and intense itching at the skin lesions, mainly on the rump, the tail head, neck and hindlimbs, similar to the signs observed in other ruminants. Only the GGT enzyme presented significantly different (P < 0.01) serum levels between intoxicated animals (n = 17) and healthy animals (n = 9), indicating liver damage in buffaloes bred in B. decumbens pastures. Microscopy of the liver showed foamy macrophages and lesions of liver disease associated with the presence of crystals in the bile ducts, which have also been found in sheep and cattle poisoned by grasses of the genus Brachiaria. During the outbreaks, protodioscin levels were higher than 3%, and shortly after, these levels were reduced to less than 0.80%, suggesting a hepatic injury etiology. The outbreaks took place at the beginning of the rainy season, and there was a positive correlation between saponin and the amount of rainfall, as well as between saponin and the amount of green leaves in the pasture. These findings indicate that the grass was more toxic in this period. This is the first report of photosensitization by B. decumbens in buffalo. PMID:23850427

Altération hydrothermale des monazites-(Ce) des pegmatites du district de Santa Maria de Itabira (Minas Gerais, Brésil)  

NASA Astrophysics Data System (ADS)

Monazite-(Ce) is found in granitic pegmatites in the Santa Maria de Itabira pegmatite district (Minas Gerais, Brazil). During the magmatic stage, monazite-(Ce) seems to have had higher contents of cheralite and huttonite in the solid solution. The Th content in primary monazite-(Ce) is high and characteristic for each pegmatite body. During the late stage (albitization), the mean LREE content in the altered zone is slightly higher and Th content is very low. The accessory mineral assemblages changed; huttonite and cheralite crystallize together with Th-poor and La-rich monazite-(Ce) at the border of altered crystals. Nd/Sm and U/Pb ratios are also changed during the hydrothermal stage.

Factors associated with alcohol intake and alcohol abuse among women in Belo Horizonte, Minas Gerais State, Brazil.  


The main objective of this cross-sectional study was to analyze factors associated with alcohol consumption among adult women living in Belo Horizonte, Minas Gerais State, Brazil, in 2011. Data for Belo Horizonte were obtained from the VIGITEL system (Telephone-Based Surveillance of Risk and Protective Factors for Chronic Diseases). Alcohol use was defined as self-reported intake of at least one dose in the previous 30 days; alcohol abuse was defined as four or more doses on at least one occasion during the same period. Polytomous logistic regression was used to evaluate factors associated with alcohol use and abuse. Alcohol use was more prevalent among women 25 to 34 years of age. Alcohol abuse was associated with age, schooling, health status, and smoking. The results suggest the need for policies to prevent alcohol abuse among women, especially targeting those who are younger, single, smokers, and with more education. PMID:23843011

[Positive breathalyzer test: factors associated with drinking and driving in the city of Belo Horizonte, Minas Gerais State, Brazil].  


Few researches in Brazil have focused on factors associated with drinking and driving. The current study presents data on the prevalence and characteristics of individuals that drive under the influence of alcohol (DUI) in nine regions of the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 1,656 drivers were interviewed, of whom 1,254 (76%) agreed to answer a structured questionnaire and submit to the breathalyzer test. The breathalyzer test was positive in 15% of these drivers. The logistic regression model predicted 1.5 times higher odds of a positive breathalyzer test in drivers over 31 years of age and 4.5 times higher in individuals that reported at least weekly alcohol consumption. In addition, drivers in the Barreiro region showed two-fold odds of a positive breathalyzer test. Focused studies with sobriety checkpoints can monitor DUI behavior, drivers' characteristics, and traffic risks, meanwhile orienting public policies to prevent drinking and driving. PMID:23370024

Paleoenvironmental and paleoclimatic investigations on Isla de los Estados, Argentina  

NASA Astrophysics Data System (ADS)

The expedition in November-December 2005 to Isla de los Estados (Staten Island) off the southeastern tip of South America was a cooperative venture between Lund University (LU) and Stockholm University (SU) in Sweden and the CADIC-CONICET Institute in Ushuaia, Argentina. The aim of the expedition was threefold: (1) to extend the Swedish paleoclimatic "ATLANTIS"-project (Greenland, Iceland, Faroe Islands, Azores, Grenada, Tristan da Cunha; PI S Björck) to the southern part of the South American continent, (2) to connect earlier glacial and climate history reconstructions from the Antarctic Peninsula to equivalents north of the Drake Passage in southernmost South America, and (3) to complement paleo-information available from the Tierra del Fuego mainland with information from Isla de los Estados. Focus was on two areas in the northern and north-western part of the island, Bahía Colnett and Bahia Crossley. Detailed geomorphologic and stratigraphic mapping of glacial deposits were combined with sampling sediments for OSL dating. To reconstruct the paleoclimatic development of Isla de los Estados since the last ice retreat, four main peat bog/lake sites were cored and sampled. In addition, living trees of Nothofagus and old logs preserved in the peat were sampled for dendrochronological and dendroclimatological studies. Preliminary results show that the deglaciation of the study area occurred before 16500 cal yr BP. Detailed multi- proxy analyses of the four sequences are under way and first results will be presented.

Projeto Vida no Vale: universal access to water and sanitation in the North East of Minas Gerais (Brazil)  

NASA Astrophysics Data System (ADS)

In the rural areas of the developing countries, the access to water supply and sanitation services is still largely inadequate. Poor governance of the water sector is frequently singled out as a cause and reforms are required. Studies analyzing the great diversity of restructuring efforts currently being undertaken in the water sector have not succeeded in determining the most appropriate institutional and economic framework for such reforms. Moreover they underline the lack of documentation on actual projects and call for concrete models and tools for improving water and sanitation services (WSS) and for adapting water utility practice to real conditions. In this context, the Vida no Vale (Life in the Valley) project is aimed at bringing universal access to WSS for all inhabitants of both urban and rural areas, in the north-eastern area of the Brazilian State of Minas Gerais. The project takes sustainable development as its guiding principle, and relies on the joint implementation of an innovative technical design, a governance model involving public participation and subsidiarity, and an economic structure combining financial viability and social equity. Designed at a consistent geographical and hydrological scale, it includes the creation of a regional subsidiary of the existing state water company as a keystone element. The institutional organisation also relies on the creation of a public board consisting of the 92 municipalities of the project region and of the State of Minas Gerais. This board will be in charge of the system's governance. This paper presents the first step of the project (2006), consisting of a feasibility study and the implementation of 9 pilot sub-projects. During the feasibility study, the supply, demand and capacity to pay for water services were defined, existing infrastructure appraised, the necessary amount of investment assessed and an innovative operational model and a sustainable management system, including civil society participation, defined. The main features of the Vida no Vale project have been tested in 9 pilot sub-projects, and implemented in municipalities chosen for their low Human Development Index and for the lack of WSS, in both urban and rural areas. A second phase corresponding to the project's final implementation will run from 2007 to 2011. The Vida no Vale project design resulted in a logical and extensive framework which could be used for developing similar WSS projects in other poor, rural regions, its adaptiveness being a key feature for taking into account the specific, local conditions.

Fault kinematics and depocenter evolution of oil-bearing, continental successions of the Mina del Carmen Formation (Albian) in the Golfo San Jorge basin, Argentina  

NASA Astrophysics Data System (ADS)

Up to 10% of the liquid hydrocarbons of the Golfo San Jorge basin come from the Mina del Carmen Formation (Albian), an ash-dominated fluvial succession preserved in a variably integrated channel network that evolved coeval to an extensional tectonic event, poorly analyzed up to date. Fault orientation, throw distribution and kinematics of fault populations affecting the Mina del Carmen Formation were investigated using a 3D seismic dataset in the Cerro Dragón field (Eastern Sector of the Golfo San Jorge basin). Thickness maps of the seismic sub-units that integrate the Mina del Carmen Formation, named MEC-A-MEC-C in ascending order, and mapping of fluvial channels performed applying geophysical tools of visualization were integrated to the kinematical analysis of 20 main normal faults of the field. The study provides examples of changes in fault throw patterns with time, associated with faults of different orientations. The "main synrift phase" is characterized by NE-SW striking (mean Az = 49°), basement-involved normal faults that attains its maximum throw on top of the volcanic basement; this set of faults was active during deposition of the Las Heras Group and Pozo D-129 formation. A "second synrift phase" is recognized by E-W striking normal faults (mean Az = 91°) that nucleated and propagated from the Albian Mina del Carmen Formation. Fault activity was localized during deposition of the MEC-A sub-unit, but generalized during deposition of MEC-B sub-unit, producing centripetal and partially isolated depocenters. Upward decreasing in fault activity is inferred by more gradual thickness variation of MEC-C and the overlying Lower Member of Bajo Barreal Formation, evidencing passive infilling of relief associated to fault boundaries, and conformation of wider depocenters with well integrated networks of channels of larger dimensions but random orientation. Lately, the Mina del Carmen Formation was affected by the downward propagation of E-W to ESE-WNW striking normal faults (mean Az = 98°) formed during the "third rifting phase", which occurs coeval with the deposition of the Upper Member of the Bajo Barreal Formation. The fault characteristics indicate a counterclockwise rotation of the stress field during the deposition of the Chubut Group of the Golfo San Jorge basin, likely associated to the rotation of Southern South America during the fragmentation of the Gondwana paleocontinent. Understanding the evolution of fault-controlled topography in continental basins allow to infer location and orientation of coeval fluvial systems, providing a more reliable scenario for location of producing oil wells.

Fault Slip Partitioning in the Eastern California Shear Zone-Walker Lane Belt: Pliocene to Late Pleistocene Contraction Across the Mina Deflection  

NASA Astrophysics Data System (ADS)

Two different mechanisms have been proposed for fault slip transfer between the subparallel NW-striking dextral- slip faults that dominant the Eastern California Shear Zone (ECSZ)-Walker Lane Belt (WLB). In the northern WLB, domains of sinistral-slip along NE-striking faults and clockwise block rotation within a zone of distributed deformation accommodated NW-dextral shear. A somewhat modified version of this mechanism was also proposed for the Mina deflection, southern WLB, whereby NE-striking sinistral faults formed as conjugate faults to the primary zone of NW-dextral shear; clockwise rotation of the blocks bounding the sinistral faults accommodated dextral slip. In contrast, in the northern ECSZ and Mina deflection, domains of NE-striking pure dip-slip normal faults, bounded by NW-striking dextral-slip faults, exhibited no rotation; the proposed mechanism of slip transfer was one of right-stepping, high angle normal faults in which the magnitude of extension was proportional to the amount of strike-slip motion transferred. New geologic mapping, tectonic geomorphologic, and geochronologic data from the Queen Valley area, southern Mina deflection constrain Pliocene to late Quaternary fault geometries, slip orientations, slip magnitudes, and slip rates that bear on the mechanism of fault slip transfer from the relatively narrow northern ECSZ to the broad deformation zone that defines the Mina deflection. Four different fault types and orientations cut across the Queen Valley area: (1) The NE-striking normal-slip Queen Valley fault; (2) NE-striking sinistral faults; (3) the NW-striking dextral Coyote Springs fault, which merges into (4) a set of EW-striking thrust faults. (U-Th)/He apatite and cosmogenic radionuclide data, combined with magnitude of fault offset measurements, indicate a Pliocene to late Pleistocene horizontal extension rate of 0.2-0.3 mm/yr across the Queen Valley fault. Our results, combined with published slip rates for the dextral White Mountain fault zone (0.3-0.8 mm/yr) and the eastern sinistral Coaldale fault (0.4 mm/yr) suggest that transfer of dextral slip from the narrow White Mountains fault zone is explained best by a simple shear couple whereby slip is partitioned into three different components: horizontal extension along the Queen Valley fault, dominantly dextral slip along the Coyote Springs fault, and dominantly sinistral slip along the Coaldale fault. A velocity vector diagram illustrating fault slip partitioning predicts contraction rates of <0.1 to 0.5 mm/yr across the Coyote Springs and western Coaldale faults. The predicted long-term contraction across the Mina deflection is consistent with present-day GPS data.

[Population dynamics and the profile of mortality in the municipality of Montes Claros, Minas Gerais State, Brazil].  


This study is an ecological study of time trend. The objective of this study is to assess the population dynamics as the 1980 Census, 1991 and 2000, and the profile of mortality in the period between 1996 and 2005, in Montes Claros, Minas Gerais State. We used the information systems database of Datasus and IBGE. The main results indicate that the elderly group increased from 4.1% in 1980, 5.0% in 1991 to 6.6% in 2000. On the proportional mortality by cause, diseases of the circulatory system were the first cause of death, and 23.05% in 1996 and 28.26% in 2005, followed by cancer 14.13% in 1996 and 15.69% in 2005, external causes of morbidity and mortality 11.87% in 1996 and 12.74% in 2005 and infectious and parasitic diseases 8.42% in 1996 and 5.43% in 2005. The profile of mortality followed the population dynamics of the city observed a reduction of infectious diseases and an increase in chronic diseases, consistent with the process of population aging.

Spatial attachment-site preferences of macroectoparasites on Atlantic sturgeons Acipenser oxyrinchus in Minas Basin, Bay of Fundy, Canada.  


Although parasite habitat preference is well studied, it is rarely rigorously evaluated statistically because of many zero intensities. Attachment-site preference and intensities of 2 macroectoparasite species ( Caligus elongatus and Calliobdella vivida ) of Atlantic sturgeon, Acipenser oxyrinchus Mitchill, in Minas Basin, Bay of Fundy, Canada, were characterized with the use of zero-inflated negative binomial statistical models that included a fork-length offset to control for body size. Three other parasites were encountered, sometimes in high numbers on various body sites, but too few counts overall prevented construction of meaningful statistical models. Of 26 sturgeons, prevalence of (1) C. elongatus (Copepoda) was 85%, mainly on caudal fins and nonfin body sites; (2) C. vivida (Hirudinea) was 81%, mainly on the pelvic and pectoral fins, and dorsal and ventral-lateral body sites; (3) Dichelesthium oblongum (Copepoda) was 31% within the gills or burrowed into the musculature at the base of fins; (4) Argulus stizostethii (Crustacea: Branchiura) was 8%; and (5) Nitzschia sturionis (Monogenea) was 12%. Only D. oblongum was associated with visible damage, mainly as lesions on gills and soft tissues. Characterizing parasite prevalences within the Bay of Fundy is important because some parasites affect fish health and population biology. PMID:21506763

Microbiological Safety of Minas Frescal Cheese (MFC) and Tracking the Contamination of Escherichia coli and Staphylococcus aureus in MFC Processing.  


Abstract Minas Frescal cheese (MFC) is a traditional food produced and consumed in Brazil, characterized by its soft texture, low sodium, and high moisture content. This study characterized the microbiological contamination by coliforms, Escherichia coli and Staphylococcus aureus, in 99 MFC samples obtained in retail sale and produced by three distinct industrial procedures. Dairy processors were selected to investigate the key points of E. coli and S. aureus contamination during cheese processing. MFC samples produced by the addition of lactic culture presented higher counts of coliforms and E. coli, when compared to other samples (p<0.05). MFC samples produced by the addition of rennet alone presented higher counts of S. aureus when compared to other samples (p<0.05). Fourteen of 19 MFC samples produced by the addition of lactic culture presented E. coli counts higher than 5×10(2) colon-forming units/g. The processing steps after pasteurization were identified as the main sources of E. coli and S. aureus contamination of MFC. Based on the results, MFC was characterized as a potential hazard for consumers due to the high frequency of samples contaminated with E. coli and S. aureus counts in noncompliance with Brazilian standards for sanitary quality and safety.

[Gravimetric characterization of potentially infectious material in urban solid waste in southern Belo Horizonte, Minas Gerais State, Brazil].  


This study investigated potentially infectious waste (feces, urine, blood, body fluids) in the composition of total municipal solid waste. From August to September 2002, solid waste samples from southern Belo Horizonte, capital of the State of Minas Gerais, were collected and sent to the solid waste treatment and disposal site at BR-040 for segregation and quantification. Sharps (objects that can cause cuts or puncture wounds) made up 0.02+/-0.02% of the collected waste, while non-sharps accounted for 5.47+/-1.11%. In the sharps category, the majority were razor blades (0.01+/-0.01%), while among non-sharps the most frequent components were toilet paper (3.00+/-0.90%), diapers (2.21+/-1.08%), and sanitary napkins (0.22+/-0.12%). Household infectious waste was twice the total amount of waste (infectious + common) from healthcare units. The study was discussed in light of the health hazards and safety aspects for formal and informal waste collectors. PMID:16751957

Boron-isotopic constraints on the petrogenesis of hematitic phyllite in the southern Serra do Espinhaço, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Metasiliciclastic rocks predominate in the lower units of the Palaeo-Mesoproterozoic Espinhaço Supergroup, in the southern Serra do Espinhaço, Minas Gerais, Brazil. The lower units also comprise rocks with locally preserved igneous fabrics, but which have very unusual chemistries. These rocks, collectively known as hematitic phyllite, are characterised by abundant fine-grained muscovite, i.e. sericite, and variable amounts of titaniferous hematite, rutile and tourmaline. Currently, the hematitic phyllite has been interpreted as a metamorphosed palaeosol after basaltic rocks and, as such, has been used as a palaeoclimatic indicator. However, the lateritic nature of the hematitic phyllite cannot unambiguously be determined because of the K metasomatism, hematitisation and tourmalinisation recorded in the hematitic phyllite and in the arenaceous country rocks. Here we report the B-isotopic and chemical compositions of tourmaline from the hematitic phyllite. Our ?11B data are in the range between - 15‰ and 4‰. The tourmaline compositions fall along the povondraite-"oxy-dravite" join, which defines a meta-evaporitic tourmaline trend. A meta-evaporitic B source is constrained by the B-isotopic data as non-marine. Our model for the hematitic phyllite suggests that B- and K-rich brines were derived from the metamorphic dewatering of non-marine evaporites. Such brines extensively altered volcanic rocks of basaltic and rhyolitic compositions, leading to tourmaline-bearing, hematite-sericite assemblages of the hematitic phyllite.

Plagioscion squamosissimus (Sciaenidae) and Parachromis managuensis (Cichlidae): a threat to native fishes of the Doce River in Minas Gerais, Brazil.  


The middle section of the lake basin of the Doce River in Minas Gerais State, Brazil is plagued by grave environmental problems, including the introduction of non-native fish, which reduces the biodiversity of this region. This study reports the presence of two newly-detected non-native species in the Doce River Basin. Sampling efforts included gill nets with mesh size of 3 to 12 mm (measured diagonally) and trawling nets, both of which were used in independent field campaigns in 2002 and 2011. The two new invasive Perciform fishes, Plagioscion squamosissimus (Heckel 1840) and Parachromis managuensis (Günther 1867) were collected in Caratinga and Rio Doce municipalities. These records and other reports on non-native fishes suggest favorable environmental conditions for the establishment of invasive species in this drainage. These invasive species have behavior and diet observed in other wide distribution exotic fish of Rio Doce Basin representing a threat to the 77 native fishes of this region, 37 of which are endangered.

Fructification phenology as an important tool in the recovery of iron mining areas in Minas Gerais, Brazil.  


'Canga' is a name given to the ferruginous rocky fields that can be found in the 'Quadrilátero Ferrífero' of Minas Gerais, Brazil. The endemism and species richness make them areas of special biological importance, regarded as high-priority for conservation. Nevertheless, they are being threatened by intense mining activity. Aiming to understand more about this flora, this study was performed in order to determine the maturation or dispersal period of the fruits of four Canga species, Alibertia vaccinioides K.Schum. (Rubiaceae), Coccoloba acrostichoides Cham. (Polygonaceae), Miconia sellowiana Naudin (Melastomataceae), and one probable new species of Calyptranthes Sw. (Myrtaceae). Although fruit maturation or dispersal tended to occur at the end of the dry season, some asynchrony was observed in these species, with food sources being available during most of the year. This shows that these species have the potential to attract animals the whole year round, and planting them for the recovery of iron mining areas may increase the community's self-regeneration capacity, leading to a more successful restoration process.

Evaluation of mosquito (Diptera: Culicidae) species richness using two sampling methods in the hydroelectric reservoir of Simplício, Minas Gerais, Brazil.  


We compared two types of light traps used for monitoring mosquito abundance in the hydroelectric reservoir of Simplício, Além Paraíba - Minas Gerais. Mosquitoes were captured bimonthly using automatic CDC and Shannon traps before the filling of the hydroelectric plant reservoir from December 2008 to December 2009. In total, 1474 specimens from 13 genera were captured. Among the captured specimens, several species known to be vectors of disease-causing agents for humans and/or animals were identified, including Anopheles aquasalis, Aedes albopictus, Coquillettidia venezuelensis, Haemagogus leucocelaenus, and Aedes scapularis. Sampling efficacy between the four capture sites was not found to be significantly different, irrespective of species captured or type of trap used. Poor correlation (r (x, y) = -0.0444) between the number of mosquito species and capture site was observed when not influenced by the type of trap used. Among the installation sites of the CDC and Shannon traps in the areas investigated, CDC traps fixed in livestock shelters obtained an overall higher abundance of species captured. PMID:22468830

Energy reserves of Artibeus lituratus (Chiroptera: Phyllostomidae) in two areas with different degrees of conservation in Minas Gerais, Brazil.  


Forest fragmentation associated with the expansion of human development is a phenomenon that occurs worldwide. Studies reveal that there have been both a decline in species diversity and a decrease in Neotropical bat population size because of habitat loss. The aim of this study was to investigate whether human action has been affecting the food availability to wildlife species, which could impact the storage of body energy reserves. For this purpose, fruit-eating bats (Artibeus lituratus) were collected in two areas in Minas Gerais state, Brazil. The concentrations of plasma glucose, as well as glycogen, lipids and protein in liver in muscles were performed, in addition to adipose tissue weight and carcass fatty acids. Our results indicate that fat reserves were significantly lower in most tested tissues (muscle of the hindlimbs, breast muscles, adipose tissue and carcass) in animals collected in the region with a higher degree of human disturbance. The other parameters showed no significant differences in the groups collected at different locations. In conclusion, we suggest that human action on the environment may be affecting the storage of body fat energy reserves of this species during the autumn, particularly in metropolitan region areas of Belo Horizonte, MG - Brazil, requiring special attention to the species conservation.

Regional sulfate-hematite-sulfide zoning in the auriferous Mariana anticline, Quadrilátero Ferrífero of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The distribution of mineral deposits, characterised as barite deposits, hematite-rich auriferous deposits and auriferous tourmaline-sulfide deposits, displays a regional sulfate-hematite-sulfide zoning along the thrust-delineated limbs of the Mariana anticline, in the south-eastern part of the Quadrilátero Ferrífero of Minas Gerais, Brazil. Cross-cut relationships of barite veins and sulfide lodes indicate that sulfidation occurred in a late-tectonic context, which is here attributed to the collapse of the ˜0.6-Ga Brasiliano thrust front. Reconnaissance S-isotopic data from barite and pyrite (Antônio Pereira barite deposit and its adjacent gold deposit, respectively), and arsenopyrite (Passagem de Mariana gold deposit), suggest a new interpretation for the hydrothermal fluid overprint in the Mariana anticline. The Antônio Pereira barite has ?33S values that are near zero, constraining the sulfate source to rocks younger than 2.45 Ga. The barite-?34S values are between +19.6 and +20.8 ‰. The Passagem arsenopyrite and tourmaline have Co/Ni ratios that define a positive linear trend with the Antônio Pereira pyrite. The latter has homogenous ?34S values, between +8.8 and +8.9 ‰, which are compatible with thermochemical reduction of aqueous sulfate with the S-isotopic composition of the Antônio Pereira barite.

Epidemiologic aspects of an outbreak of Trypanosoma vivax in a dairy cattle herd in Minas Gerais state, Brazil.  


The aim of this study was to assess the epidemiological situation of bovine trypanosomiasis caused by Trypanosoma vivax in a dairy cattle herd from Igarapé, Minas Gerais state, Brazil. The herd was monitored from September 2007 to February 2009 by sampling blood for determination of packed cell volume (PCV), microhaematocrit centrifugation test of parasitaemia (MHCT), serology (IFA), morphological identification of T. vivax and molecular diagnosis by polymerase chain reaction (PCR). During all the experimental period, 25 animals were MHCT and PCR positive, considering that in each sample collection a mean of 70 animals was evaluated. The morphometric characteristics of trypomastigote forms confirmed the infection by T. vivax. The seroprevalence ranged from 7.4% in September 2007 to 48% in February 2009, and the highest incidence observed could be correlated with an increased population of Stomoxys calcitrans flies in that region. Anaemia was the most important change found in infected animals, which showed lower averages of PCV than parasitologically negative animals (p<0.0001). Infected individuals showed lower averages of PCV than parasitologically negative animals (p<0.0001), indicating higher anaemia in the former compared with the latter group. PMID:20138431

Mortality of the defoliator Euselasia eucerus (Lepidoptera: Riodinidae) by biotic factors in an Eucalyptus urophylla plantation in Minas Gerais State, Brazil.  


Euselasia eucerus (Hewitson, 1872) (Lepidoptera: Riodinidae) is a Brazilian native species commonly found in Eucalyptus plantations. Biotic mortality factors of this defoliator were studied in a Eucalyptus urophylla plantation in Minas Gerais State, Brazil aiming to identify natural enemies and their impact on this insect. Euselasia eucerus had biotic mortality factors during all development stages. The most important were Trichogramma maxacalii Voegelé and Pointel, 1980 (Hymenoptera: Trichogrammatidae) during egg stage (48.9%), a tachinid fly (Diptera: Tachinidae) during larval stages (10%) and Itoplectis sp. (Hymenoptera: Ichneumonidae) during pupal stage (52.2%). The parasitism rate was higher in the basal part of the plant canopy (37.8%). PMID:19274332

The purpose of this research was to verify the existence of a spatial correlation between base station (BS) clusters and cases of deaths by neoplasia in the Belo Horizonte municipality, Minas Gerais state, Brazil, from 1996 to 2006 and to measure the human exposure levels to EMF where there is a major concentration of cellular telephone transmitter antennas. A descriptive spatial analysis of the BSs and the cases of death by neoplasia identified in the municipality was performed through an ecological-epidemiological approach, using georeferencing. The database employed in the survey was composed of three data banks: 1. death by neoplasia documented by the Health Municipal Department; 2. BSs documented in ANATEL ("Agência Nacional de Telecomunicações": 'Telecommunications National Agency'); and 3. census and demographic city population data obtained from official archives provided by IBGE ("Instituto Brasileiro de Geografia e Estatística": 'Brazilian Institute of Geography and Statistics'). The results show that approximately 856 BSs were installed through December 2006. Most (39.60%) of the BSs were located in the "Centro-Sul" ('Central-Southern') region of the municipality. Between 1996 and 2006, 7191 deaths by neoplasia occurred and within an area of 500 m from the BS, the mortality rate was 34.76 per 10,000 inhabitants. Outside of this area, a decrease in the number of deaths by neoplasia occurred. The greatest accumulated incidence was 5.83 per 1000 in the Central-Southern region and the lowest incidence was 2.05 per 1000 in the Barreiro region. During the environmental monitoring, the largest accumulated electric field measured was 12.4 V/m and the smallest was 0.4 V/m. The largest density power was 40.78 ?W/cm(2), and the smallest was 0.04 ?W/cm(2). PMID:21741680

Genotype and mating type distribution within clinical Cryptococcus neoformans and Cryptococcus gattii isolates from patients with cryptococcal meningitis in Uberaba, Minas Gerais, Brazil.  


We molecularly characterized 81 cryptococcal isolates recovered from cerebrospinal fluid samples of 77 patients diagnosed between 1998 and 2007 as having cryptococcal meningitis in Uberaba Minas Gerais, Brazil. Fifty-seven (74%) were male with a mean age 35.6 years. Seventy-two (88.9%) of the isolates were from 68 AIDS patients and cryp-tococcosis was the first AIDS-defining condition in 38 (55.9%) patients. Cryptococcosis and AIDS were simultaneously diagnosed in 25 (65.8%) of these 38 patients. Genotypes were characterized through the use of URA5 restriction fragment length polymorphisms analysis, the genetic variability was determined using PCR-fingerprinting with the minisatellite-specific primer M13, and the mating type and serotypes were established by PCR. Seventy-six of the 81 isolates were Cryptococcus neoformans (93.8%), while the remaining five were C. gattii (6.1%), but all were mating type alpha. C. neoformans isolates were genotype VNI (serotype A), while C. gattii isolates were VGII. Four of the latter isolates were identical, but only two were from AIDS patients. Six of the nine isolates from non-AIDS patients were VNI. PCR fingerprints of the isolates from two of the three AIDS patients with clinical relapse were 100% identical. The predominance of VNI and mating type alpha is in accordance with data from other parts of the world. The occurrence of VGII in Minas Gerais indicates a geographical expansion within Brazil.

Ochoterenella esslingeri n. sp. (Nematoda: Onchocercidae: Waltonellinae) from Bokermannohyla luctuosa (Anura: Hylidae) in Minas Gerais, Brazil, with notes on Paraochoterenella Purnomo & Bangs, 1999  

PubMed Central

The waltonelline Ochoterenella esslingeri n. sp., a filarial parasite of the anuran Bokermannohyla luctuosa in Minas Gerais, Brazil is described. Several characters distinguish this new species from the 15 species presently included in the genus: the cuticular ornamentation of the female that is restricted to the posterior region of the body, the irregular arrangement of the small, rounded bosses, the postoesophageal vulva, the short glandular oesophagus, the size and shape of the microfilariae, the long left spicule and high spicular ratio. Irregularly arranged, tiny, rounded bosses are common in the monotypic genus Paraochoterenella from an Indonesian ranid, which is not well defined but likely valid. In the Neotropical Realm, the type hosts of the species of Ochoterenella are Hylidae (O. esslingeri n. sp.), Leptodactylidae (two species) and the remaining 13 species were described from the giant toad Rhinella marina (Bufonidae).

The unique karyotype of Henochilus wheatlandii, a critically endangered fish living in a fast-developing region in Minas Gerais State, Brazil.  


Henochilus wheatlandii, the only species of this genus, is critically endangered and was considered extinct for over a century. The rediscovery of this fish in 1996 made it possible to study its phylogenetic relationships with other species in the subfamily Bryconinae. The aim of this study was to characterise the karyotype of H. wheatlandii. Standard staining, C-positive heterochromatin and nucleolar organiser region (NOR) banding, chromomycin A(3) staining, and fluorescent in situ hybridisation (FISH) using 5S rDNA and 18S rDNA probes were conducted on nineteen specimens collected in the Santo Antonio River, a sub-basin of the Doce River in Ferros municipality, Minas Gerais State, Brazil. Henochilus wheatlandii shared the same diploid number and chromosome morphology as other species of Bryconinae. However, its heterochromatin distribution patterns, NOR localisation, and FISH patterns revealed a cytogenetic profile unique among Neotropical Bryconinae, emphasizing the evolutionary uniqueness of this threatened species.

[A comparison of the Family Health Strategy to other sources of healthcare: utilization and quality of health services in Belo Horizonte, Minas Gerais State, Brazil].  


Indicators of healthcare utilization and quality were compared in a probabilistic sample of adults (N = 7,534) covered by private health plans, the Family Health Strategy (FHS), and "traditional" primary care clinics (UBS) in Belo Horizonte, Minas Gerais State, Brazil. After adjusting for demographics, health conditions, and socioeconomic status, indicators of healthcare utilization (longitudinality, health-seeking, and medical consultations) showed better performance among users of the FHS and private health plans compared to those covered by the UBS. Hospitalizations, preventive tests, and flu vaccinations varied little between sources of care. Quality indicators (difficulty in making an appointment, waiting lines, complaints about obtaining medications, and receiving an appointment within 24 hours) were better among private health plans. Recommending one's healthcare providers to others was more frequent among FHS users (61.9%) and those with private health plans (55.6%), compared to those served by UBS (45.4%). PMID:23843004

Water Resources Estimation of the Biosphere Reserve "Sierra de las Minas" in Guatemala, by Using a Distributed Hydrological Model and Considering Lack of Data  

NASA Astrophysics Data System (ADS)

The UNESCO Biosphere Reserve "Sierra de las Minas" is part of the Guatemalan System of Protected Areas and contains the largest cloud forests of Guatemala. Its southern slopes flow into the Motagua Valley, one of the more active zones in the country and paradoxically, the most arid and driest zone of Central America. The main objective of this work was to obtain a better estimation of the water resources coming from the southern slopes of the "Sierra de las Minas", and to have an analysis tool to better understand key hydrological processes involved on water sustainable management practices, as the environmental services initiatives on the zone. Unfortunately, the lack of data was the general framework. The selected model was the so called TETIS, which is a conceptual distributed model developed by our research group. A simple and efficient method was used for parameter maps estimation with a 100 m cell size. The model was calibrated at daily time step in the Teculután basin with 187 km2, by applying a new split-parameter structure coupled with the SCE-UA automatic optimization algorithm, in order to obtain the set of optimal correction factors of the model. For a period of medium daily precipitation within the validation period, we obtained a simulated discharge very close to the observed data (the monthly Nash and Sutcliffe model efficiency coefficient was 0.83). We present here a precipitation spatial and sensitivity analysis, and a simple approach for estimate the contribution of cloud forests to the hydrological balance. Finally, the calibration results were extrapolated to the Uyús ungaged basin to simulate its flow regime and to evaluate its water resources.

High sero-prevalence of caseous lymphadenitis identified in slaughterhouse samples as a consequence of deficiencies in sheep farm management in the state of Minas Gerais, Brazil  

PubMed Central

Background Caseous lymphadenitis (CLA), caused by Corynebacterium pseudotuberculosis, is one of the most important diseases of sheep and goats, causing considerable economic losses for herd owners. Results We assessed the seroprevalence of infection with C. pseudotuberculosis in 805 sheep from 23 sheep farms that supply slaughterhouses in the state of Minas Gerais; we also analyzed management practices that could be associated with CLA occurrence, used on these and nearby farms that also supplied animals to the slaughterhouse (n = 60). The serum samples for assaying CLA infection were taken at the slaughterhouse. Frequency of infection with C. pseudotuberculosis was estimated at 43.7%, and farm frequency was estimated at 100%. Management practices were analyzed through a questionnaire. All farmers (60/60) had extensive/semi-extensive rearing system; 70.0% (42/60) identified sheep individually; 11.7% (7/60) had periodical technical assistance; 41.7% (25/60) disinfected the facilities; 86.7% (52/60) used barbed wire fences and did not implement adequate CLA control measures; only 11.7% (7/60) of breeders reported vaccination against C. pseudotuberculosis; 13.3% (8/60) took note of animals with clinical signs of CLA; 1.7% (1/60) opened and sanitized abscesses, and isolated the infected animals; 10.0% (6/60) knew the zoonotic potential of this disease and 1.7% (1/60) of the farmers culled animals in case of recurrence of abscesses. Conclusions It can be concluded that C. pseudotuberculosis infection is widely spread in sheep flocks in Minas Gerais state in Brazil and that there is a lack of good management measures and vaccination, allowing transmission of this infectious agent throughout the production network.



The chemical composition of specular hematite from Tilkerode, Harz, Germany: implications for the genesis of hydrothermal hematite and comparison with the Quadrilátero Ferrífero of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The black shale-hosted selenide vein-type deposit at Tilkerode, eastern Harz, Germany, has specular hematite enclosed in clausthalite (PbSe). The specular hematite has Ti and V in amounts of up to ˜1 wt.% TiO2 and ˜3 wt.% V2O5, and subordinate, but important, contents of Mo (22-372 ppm) and B (up to 68 ppm). The Tilkerode hematite serves as a reference for hydrothermal hematite formed at relatively low temperatures (<150 °C). The composition of the Tilkerode hematite is compared with that of two generations of specular hematite from itabirite-hosted iron-ore deposits in the Quadrilátero Ferrífero of Minas Gerais, Brazil. The first generation of specular hematite represents an early tectonic hematitisation of dolomitic itabirite at Águas Claras and occurs as fine-grained crystals. Reconnaissance data indicate that the Águas Claras hematite is poorer in Ti and V, relative to the Tilkerode hematite, but has ˜5-10 ppm B and ˜7-11 ppm Li. The second generation of specular hematite defines the pervasive tectonic foliation of the Gongo Soco iron ore. This hematite has Ti contents of up to ˜2 wt.% TiO2 and subordinate amounts of V (62-367 ppm); its B and Li concentrations are mostly below <2 ppm B and <1 ppm Li. The presence of Ti and B in the Tilkerode hematite can be explained by highly saline, B-bearing fluids that were capable of mobilising otherwise immobile Ti. The Mo signature of the Tilkerode hematite suggests that Mo was derived from the host black shale. In Minas Gerais, B and Li were incorporated into the early tectonic hematite from saline fluids at relatively low temperatures (Águas Claras) and then released during metamorphic hematite growth at higher temperatures, as suggested by the foliation-defining hematite without B-Li signature (Gongo Soco).

Seroprevalence and risk factors of toxoplasmosis in cattle from extensive and semi-intensive rearing systems at Zona da Mata, Minas Gerais state, Southern Brazil  

PubMed Central

Background Concerning the infection of humans by T. gondii, limited efforts have been directed to the elucidation of the role of horizontal transmission between hosts. One of the main routes of transmission from animals to humans occurs through the ingestion of raw or insufficiently cooked meat. However, even though the detection of T. gondii in meat constitutes an important short-term measure, control strategies can only be accomplished by a deeper understanding of the epidemiology of toxoplasmosis. The present study aimed to investigate the seroprevalence of toxoplasmosis in cattle from Zona da Mata, Minas Gerais, Brazil, and to identify associated risk factors, through an epidemiological investigation. Methods The animals studied (Bos indicus, breed Nelore or Gir) were reared in the Zona da Mata micro-region and killed at a commercial slaughterhouse at Juiz de Fora, Minas Gerais state. The animals came from 53 cattle farms with extensive (predominantly pasture feeding management) or semi-intensive (food management based on grazing, salt mineral and feed supplementation) rearing systems. Blood samples were collected from 1200 animals, and assigned to Indirect Fluorescent Antibody Test. Results When analyzing IgG anti-T.gondii we found an overall seroprevalence of 2.68%. In Brazil prevalences vary from 1.03% to 60%. Although in the present study, the seroprevalence per animal is considered low compared to those observed in other studies, we found out that of the 53 farms analyzed, 17 (34.69%) had one or more positive cattle. It is a considerable percentage, suggesting that the infection is well distributed through the Zona da Mata region. The results of the epidemiological investigation showed that the main risk factors of Toxoplasma gondii infection are related to animal management and to the definive host. There was a relationship between the number of seropositive cattle and the presence and number of resident cats, presence and number of stray cats, presence of cats walking freely, rat control by using cats and feed storage. Conclusion These results may contribute to the development of preventive strategies in Brazil and other developing countries were extensive and semi-intensive cattle rearing systems are very widespread and the efforts to control this important zoonotic disease have attained little success.



Optimization methods for gas liquefaction production in Algeria and for a firewater safety system for the Holy Area of Mina, in Saudi Arabia  

SciTech Connect

The major part of this study deals specifically with problems encountered in liquefied-gas production in Algeria. However, its developed methodology could be applied to other industrial units of similar importance (petrochemical, pipeline, etc.). Capital costs as well as manpower, operations, and maintenance costs are very high in such production, especially in Algeria, a foreign-technology dependent country. Moreover, the technical complexity of an LNG plan constitutes a further incentive for the formulation of mathematical models as tools toward attaining management efficiency. These models can form the basis for Decision Support Systems for use as well in improving the operations of any major national industrial plant. The remainder of the dissertation consists of a conception and a study for an optimal firewater safety system for the Holy Area of Mina, in Saudi Arabia, where fire outbreaks cause significant losses in lives and property damages during the yearly pilgrimage. Part of the contribution of this study lies in the guidelines established for a Decision Support System, which will improve the user's effectiveness as a decision maker.

[Nutritional profile of the Xukuru-Kariri indigenous people in the state of Minas Gerais in accordance with different anthropometric and body composition indicators].  


The scope of this study was to evaluate the nutritional profile of indigenous Xukuru-Kariri villagers in the state of Minas Gerais between seven and seventy-eight years of age in accordance with the different anthropometric and body composition indicator. The measurements were: weight, height, waist circumference (WC) and body fat percentage (BF%). The sensitivity and specificity of anthropometric indices were calculated with a confidence interval of 95% and positive predictive value (PPV) and negative predictive value (NPV). A total of 58 individuals was evaluated, of which 56.9% (n =33) were male and 43.1% (n =25) were female. Specificity was greater than sensitivity in all indices. It was seen that 29% of individuals were classified as having excess body fat as assessed by BMI and hand-to-hand bioimpedance and 50% of subjects had high body fat in relation to BMI and WC. Studies need to be conducted with different ethnic groups in order to construct indicators for specific nutritional guidance of indigenous health services. PMID:23358766

[Evaluation of labor-related and physical risk factors for cardiovascular disease in drivers of urban transport buses in Montes Claros in the state of Minas Gerais].  


The scope of this study was to evaluate risk factors for cardiovascular disease among bus drivers in Montes Claros in the state of Minas Gerais. A semi-structured questionnaire covering personal, anthropometric, professional and labor-related data was used, in addition to a questionnaire on the level of stress. 53 bus drivers were surveyed and the average age was 30 to 39 years of age. 81.1% were non-smokers; 58% of the sample were teetotalers; and 50% took regular exercise. In the assessment of BMI, 40 drivers (75.4%) were overweight. The prevalence in eating habits revealed excess consumption of sugar (66.0%), fat (64.2%), coffee (69.8%), salt (60.4%), coca cola (64.2%) and soft drinks (54.7%). Among reports of chronic diseases, no diabetic (98.1%) or hypertensive (94.3%) drivers were observed. Most of the sample (69.7%) had normal stress levels. With respect to laboratory data, the vast majority of drivers had hypertriglyceridemia and hypercholesterolemia. HDL levels were satisfactory, and the LDL revealed normal and desirable levels in more than half of the sample. The prevalence of cardiovascular disease was low. PMID:22899155

Oxidation states of iron as an indicator of the techniques used to burn clays and handcraft archaeological Tupiguarani ceramics by ancient human groups in Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Ceramics of the Tupiguarani Tradition typically have in common the burning characteristics, their forms and decoration motifs. Dating such ceramic pieces with the radiocarbon method indicate that these artifacts were probably handcrafted between 1,500 and 500 years before the present. Fragments ceramic utensils were collected in the archaeological site of Beltrão, in the municipality of Corinto, state of Minas Gerais, Brazil. A fragment of about 50 mm in diameter and 15 mm thick, with a color gradation across the ceramic wall ranging from red, on one side, grayish, in the middle, and orange, on the opposite side, was selected for a more detailed examination. The fragment was transversely cut and a series of subsamples were separated from different points along the piece wall, in layer segments of ~3 mm. All subsamples were analyzed with Mössbauer spectroscopy at room temperature and 80 K. Results reveal that hematite is the magnetically ordered phase. A Fe2 + component (relative spectral area, 50 %) appears for the grayish subsample. According to these first results, the red subsample seems to be the side that had direct contact with fire used to burn the precursor clay in air. The grayish middle layer is probably due to the clay mixed with some ashes. Mössbauer data reveal that the orange layer, corresponding to the opposite side of the ceramic relatively to the direct fire, does contain about the same Fe2 + :Fe3 + ratio but much lower proportion of ?-Fe2O3 than the red layer.

Talc mineralisation associated with soft hematite ore, Gongo Soco deposit, Minas Gerais, Brazil: petrography, mineral chemistry and boron-isotope composition of tourmaline  

NASA Astrophysics Data System (ADS)

Talc mineralisation occurs as hematite-talc schist between soft hematite ore and dolomitic itabirite at Gongo Soco, Quadrilátero Ferrífero of Minas Gerais, Brazil. The hematite-talc schist and soft hematite have a prominent tectonic foliation of tabular hematite. Tabular hematite without preferential orientation is superimposed on the tectonic foliation. The talcose schist is enriched in F and has a constant Fe/S ratio. Electron-microprobe analyses indicate trace amounts of S in different generations of hematite. The whole-rock Fe/S ratio possibly represents sulfate S from hematite-hosted fluid inclusions. Fluid inclusions in foliation-overprinting hematite and chlorite geothermometry from talcose rocks suggest, respectively, temperatures from <200°C to ~300°C. Tourmaline, a rarely observed mineral in the hematite-talc schist, belongs to the alkali group and falls in the dravite compositional field. Boron-isotope determinations of tourmaline crystals, using secondary ion mass spectrometry, vary from -20‰ to -12‰ ?11B. This compositional isotopic range and the tourmaline chemical composition suggest a meta-evaporitic origin. A non-marine evaporitic setting is the most likely source of acidic, highly oxidising fluids, which resulted in the abundant F-bearing talc and the presence of otherwise immobile Ti in hematite. Oxidising brines were channelled along shear zones and converted dolomitic itabirite into the Gongo Soco soft hematite and the talc mineralisation. The latter is envisaged as the hydrothermal wall-rock alteration of dolomitic itabirite, which gave rise to the soft hematite ore.

Acute schistosomiasis outbreak in the metropolitan area of Belo Horizonte, Minas Gerais: alert about the risk of unnoticed transmission increased by growing rural tourism.  


The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention. PMID:14595449

[From guidelines to practice: evaluation of the pediatric care provided by a service of secondary reference in the north of the State of Minas Gerais].  


In the State of Minas Gerais, the Secondary Reference Viva Vida Centers (CVVRS) are one of the strategies deployed to tackle the problems in child health. This study sought to evaluate pediatric care provided in a CVVRS, using the guidelines defined when it was set up as a benchmark. A quantitative-qualitative approach was adopted, which included a cross-sectional study with stratified random sampling of 385 medical records of children registered with the program between 2007 and 2009, and analysis of focus groups with strategic actors of the initiative. There were divergences between the user profiles and the target audience in terms of age, hometown and clinical characteristics. Access and use of the service differed depending on the town, due to problems of misinformation concerning the proposal, difficulty of transportation and the fragility of the health network. The centers are considered an innovative and important initiative for the expansion and organization of the health network, though the intended logic is not effectively seen in practice. Interventions for articulation between the network services and adaptation of the agreed guidelines to the regional specificities are necessary. PMID:23752544

Xenotime-hematite aggregates on opaline filaments: evidence for biomineralization in weathered siliciclastic rocks, Capanema, Quadrilátero Ferrífero of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Dissolution cavities in weathered pebbly quartzite of the ~2.5-Ga Moeda Formation at Capanema, Quadrilátero Ferrífero of Minas Gerais, Brazil, are decorated with suspended filaments of opaline silica. The filaments sustain xenotime-hematite aggregates in the open space. Xenotime occurs as inclusions in buds and botryoidal aggregates of hematite. The filamentous structures consist of strand-forming buds, hypha-like extensions, and thin strands that compose mat-like arrangements. They resemble microbial filaments that were replaced by opaline silica and fossilized. The occurrence of spherical hematite as protuberances on hematite-free opaline hyphae is interpreted as accretion of dissolved iron onto extracellular polymers. Phosphate sites in polymeric substances expelled from the microbial filaments might have adsorbed yttrium and heavy rare-earth elements from groundwater to the iron-accreting polymers. These would have resulted in botryoidal aggregates of hematite with xenotime inclusions. The presence of authigenic xenotime in the weathering zone opens a new possibility to constrain the evolution of lateritic profiles by xenotime geochronology.

The Glória quartz-monzodiorite: isotopic and chemical evidence of arc-related magmatism in the central part of the Paleoproterozoic Mineiro belt, Minas Gerais State, Brazil.  


The Glória quartz-monzodiorite, one of the mafic plutons of the Paleoproterozoic Mineiro belt, is intrusive into banded gneisses, amphibolites, schists and phyllites of the Rio das Mortes greenstone belt, in the southern portion of the São Francisco Craton, State of Minas Gerais, Brazil. The Glória quartz-monzodiorite yields a SHRIMP U-Pb zircon age of 2188 +/- 29 Ma, suggesting a tectonic relationship with the pre-collisional phase of the Mineiro belt. According to the Nd isotopic evidence (epsilonNd(T) = -3.4; T DM = 2.68 Ga) the original magmas was formed by a mixture among Archean crustal material and Paleoproterozoic juvenile magma. The Glória quartz-monzodiorite shows metaluminous and calc-alkaline tendency with intermediate K content, comparable to that of volcanic-arc rocks. The primary mineralogical assemblage was partly modified by metamorphism, dated between 2131-2121 Ma in nearby coeval plutons. Such metamorphism is significantly older than the reported metamorphic episodes of the Mineiro belt in the Quadrilátero Ferrífero region (2059-2041 Ma) in the eastern portion of the study area. This evidence, together with chemical and isotopic data from other mafic and felsic plutons coeval with the Glória quartz-monzodiorite, indicate a tectonic and magmatic migration within the Mineiro belt from west to east.

Spotted fever group Rickettsia in small rodents from areas of low endemicity for Brazilian spotted fever in the eastern region of Minas Gerais State, Brazil.  


We investigated the humoral immune response against different species of Rickettsia in serum samples from small rodents collected in two areas of a silent focus for Brazilian spotted fever in the eastern region of Minas Gerais State, Brazil. Sera samples were analyzed by indirect immunofluorescence assay using antigens from Rickettsia species of the spotted fever, ancestral, and transition groups. Titers ? 1:64 were considered positive. In Santa Cruz do Escalvado, 94% (30 of 32) of the samples collected from Rattus rattus, 22% (5 of 23) from Nectomys squamipes, and 80% (4 of 5) from Akodon sp., reacted by indirect immunofluorescence assay with Rickettsia antigens of the spotted fever group. In the municipality of Pingo D'Água, 84% (26 of 31) of the samples collected from R. rattus, 86% (6 of 7) of the samples from Oryzomys subflavus, 86% (6 of 7) from N. squamipes, and 100% (1 of 1) from Bolomys sp. contained antibodies that reacted with rickettsial antigens of the spotted fever group. These results demonstrated the previous exposure of small rodents to spotted fever group Rickettsia, suggesting the participation of these animals in the natural history of these rickettsiae in this region.

NASA Astrophysics Data System (ADS)

The mineral natrodufrénite a secondary pegmatite phosphate mineral from Minas Gerais, Brazil, has been studied by a combination of scanning electron microscopy and vibrational spectroscopic techniques. Electron probe analysis shows the formula of the studied mineral as (Na0.88Ca0.12)?1.00(Fe0.722+Mn0.11Mg0.08Ca0.04Zr0.01Cu0.01)?0.97(Fe4.893+Al0.02)?4.91(PO4)3.96(OH6.15F0.07)6.22?2.05(H2O). Raman spectroscopy identifies an intense peak at 1003 cm-1 assigned to the PO43- ?1 symmetric stretching mode. Raman bands are observed at 1059 and 1118 cm-1 and are attributed to the PO43- ?3 antisymmetric stretching vibrations. A comparison is made with the spectral data of other hydrate hydroxy phosphate minerals including cyrilovite and wardite. Raman bands at 560, 582, 619 and 668 cm-1 are assigned to the ?4PO43- bending modes and Raman bands at 425, 444, 477 and 507 cm-1 are due to the ?2PO43- bending modes. Raman bands in the 2600-3800 cm-1 spectral range are attributed to water and OH stretching vibrations. Vibrational spectroscopy enables aspects of the molecular structure of natrodufrénite to be assessed.

Far-field effects of tidal energy extraction in the Minas Passage on tidal circulation in the Bay of Fundy and Gulf of Maine using a nested-grid coastal circulation model  

NASA Astrophysics Data System (ADS)

The Bay of Fundy in eastern Canada has the highest tides in the world. Harnessing the tidal energy in the region has long been considered. In this study, the effects of tidal in-stream energy extraction in the Minas Passage on the three-dimensional (3D) tidal circulation in the Bay of Fundy (BoF) and the Gulf of Maine (GoM) are examined using a nested-grid coastal ocean circulation model based on the Princeton Ocean Model (POM). The nested-grid model consists of a coarse-resolution (~4.5 km) parent sub-model for the GoM and a high-resolution (~1.5 km) child sub-model for the BoF. The tidal in-stream energy extraction in the model is parameterized in terms of nonlinear Rayleigh friction in the momentum equation. A suite of numerical experiments are conducted to determine the ranges of extractable tidal in-stream energy and resulting effects on the 3D tidal circulation over the Bay of Fundy and the Gulf of Maine (BoF-GoM) in terms of the Rayleigh friction coefficients. The 3D model results suggest that the maximum energy extraction in the Minas Passage increases tidal elevations and tidal currents throughout the GoM and reduces tidal elevations and circulation in the upper BoF, especially in the Minas Basin. The far-field effect of tidal energy extraction in the Passage on the 3D tidal circulation in the BoF-GoM is examined in two cases of harnessing tidal in-stream energy from (a) the entire water column and (b) the lower water column within 20 m above the bottom in the Passage. The 3D model results demonstrate that tidal in-stream energy extraction from the lower water column has less impact on the tidal elevations and circulation in the BoF-GoM than the energy extraction from the whole water column in the Minas Passage.

[Evaluation of a program for the control of schistosomiasis in municipalities located on the basin of the Sao Francisco River, Minas Gerais, Brazil].  


An evaluation of the control program on schistosomiasis (PCE/PCDEN) was performed in the region of São Francisco river in MInas Gerais. The study area comprises six municipalities, with 130,000 inhabitants and 916 localities situated in an area with 10,722 km2. The activities initiated in 1983-85 in four municipalities and in 1987 in the other two. The main measures of control were repeated treatment with oxamniquine and use of niclosamide. The prevalence of infection by Schistosoma mansoni in the first four municipalities, that was initially around 18 and 32%, dropped abruptly after the first intervention (1983/85) and remained in levels below the initial ones until the last assessment (1990-94); similar trends were observed for the proportion of infected snails. In these municipalities, the proportion of localities without infection or with prevalence below 5% increased in relation to those with higher prevalence. In the other two municipalities, with initial prevalence below 5%, there were no substantial changes in S. mansoni prevalence or proportion of infected snails; the cost benefit of the program in these municipalities need to be assessed and the priorities redirected to eradicate focal areas and prevent spread to non infected localities. The authors call attention to the difficulties in the long term of a control program based on repeated treatments. Information on factors associated with S. mansoni infection in each locality, or in groups of similar localities, would allow to develop additional measures to treatment that could last longer and be less dependent on the continuous use of chemotherapy.

Detection of Theileria and Babesia in brown brocket deer (Mazama gouazoubira) and marsh deer (Blastocerus dichotomus) in the State of Minas Gerais, Brazil.  


Intraerythrocytic protozoan species of the genera Theileria and Babesia are known to infect both wild and domestic animals, and both are transmitted by hard-ticks of the family Ixodidae. The prevalences of hemoprotozoa and ectoparasites in 15 free-living Mazama gouazoubira, two captive M. gouazoubira and four captive Blastocerus dichotomus from the State of Minas Gerais, Brazil, have been determined through the examination of blood smears and the use of nested polymerase chain reaction (nPCR). The cervid population was inspected for the presence of ticks and any specimens encountered were identified alive under the stereomicroscope. Blood samples were collected from all 21 animals, following which blood smears were prepared, subjected to quick Romanowsky staining and examined under the optical microscope. DNA was extracted with the aid of commercial kits from cervid blood samples and from tick salivary glands. The nPCR assay comprised two amplification reactions: the first was conducted using primers specific for a 1700 bp segment of the 18S rRNA gene of Babesia and Theileria species, whilst the second employed primers designed to amplify a common 420 bp Babesia 18S rRNA fragment identified by aligning sequences from Babesia spp. available at GenBank. The ticks Amblyomma cajennense, Rhipicephalus microplus and Dermacentor nitens were identified in various of the cervids examined. Of the animals investigated, 71.4% (15/21) were infected with hemoprotozoa, including Theileria cervi (47.6%), Theileria sp. (14.3%), Babesia bovis (4.8%) and Babesia bigemina (4.8%). However, only one of the infected wild cervids exhibited accentuated anaemia (PCV=17%). This is first report concerning the occurrence of Theileria spp. in Brazilian cervids. PMID:21354704

Population demography of Northern muriquis (Brachyteles hypoxanthus) at the Estação Biológica de Caratinga/Reserva particular do Patrimônio Natural-Felìciano Miguel Abdala, Minas Gerais, Brazil.  


The 957-ha forest at the Estação Biológica de Caratinga/Reserva Particular do Patrimônio Natural-Felìciano Miguel Abdala, in Minas Gerais, Brazil, supports one of the largest known populations of the critically endangered northern muriqui (Brachyteles hypoxanthus). We combine long-term data on one group that has been monitored since 1982 with new data obtained on the other three groups since 2002 and 2003 to describe the demographic structure of this population, evaluate its potential for future growth, and predict how dispersal and competitive regimes may change in response to current demographic conditions. As of January 2005, the 226 individuals in the population were divided into four mixed-sex groups with 37-77 members, and an all-male unit whose eight males maintained transient associations with two of the mixed-sex groups. Although 51.77% of the population was female, the sex ratio among adults and subadults was female-biased (0.75), while that among immatures was male-biased (1.47). Consistent with expectations from mean interbirth intervals, 64.18% of adult females gave birth in 2003 and 2004. However, by January 2005, only 52.31% of adult females were still carrying infants <24 months of age due to unusually high infant mortality. First-year survivorship among the 25 infants born in the population in 2003 was only 76%, considerably lower than previously documented in the longest-studied group. High female fecundity is indicative of a healthy population, but the current male bias in births will result in a decline in the population growth rate within two decades, and may increase levels of male reproductive competition and alter dispersal patterns.

Hidden Diversity Behind the Zombie-Ant Fungus Ophiocordyceps unilateralis: Four New Species Described from Carpenter Ants in Minas Gerais, Brazil  

PubMed Central

Background Ophiocordyceps unilateralis (Clavicipitaceae: Hypocreales) is a fungal pathogen specific to ants of the tribe Camponotini (Formicinae: Formicidae) with a pantropical distribution. This so-called zombie or brain-manipulating fungus alters the behaviour of the ant host, causing it to die in an exposed position, typically clinging onto and biting into the adaxial surface of shrub leaves. We (HCE and DPH) are currently undertaking a worldwide survey to assess the taxonomy and ecology of this highly variable species. Methods We formally describe and name four new species belonging to the O. unilateralis species complex collected from remnant Atlantic rainforest in the south-eastern region (Zona da Mata) of the State of Minas Gerais, Brazil. Fully illustrated descriptions of both the asexual (anamorph) and sexual (teleomorph) stages are provided for each species. The new names are registered in Index Fungorum ( and have received IF numbers. This paper is also a test case for the electronic publication of new names in mycology. Conclusions We are only just beginning to understand the taxonomy and ecology of the Ophiocordyceps unilateralis species complex associated with carpenter ants; macroscopically characterised by a single stalk arising from the dorsal neck region of the ant host on which the anamorph occupies the terminal region and the teleomorph occurs as lateral cushions or plates. Each of the four ant species collected - Camponotus rufipes, C. balzani, C. melanoticus and C. novogranadensis - is attacked by a distinct species of Ophiocordyceps readily separated using traditional micromorphology. The new taxa are named according to their ant host.

Vibrational spectroscopy of the phosphate mineral lazulite--(Mg, Fe)Al2(PO4)2·(OH)2 found in the Minas Gerais, Brazil.  


This research was done on lazulite samples from the Gentil mine, a lithium bearing pegmatite located in the municipality of Mendes Pimentel, Minas Gerais, Brazil. Chemical analysis was carried out by electron microprobe analysis and indicated a magnesium rich phase with partial substitution of iron. Traces of Ca and Mn, (which partially replaced Mg) were found. The calculated chemical formula of the studied sample is: (Mg0.88, Fe0.11)Al1.87(PO4)2.08(OH)2.02. The Raman spectrum of lazulite is dominated by an intense sharp band at 1060 cm(-1) assigned to PO stretching vibrations of of tetrahedral [PO4] clusters presents into the HPO4(2-) units. Two Raman bands at 1102 and 1137 cm(-1) are attributed to both the HOP and PO antisymmetric stretching vibrations. The two infrared bands at 997 and 1007 cm(-1) are attributed to the ?1PO4(3-) symmetric stretching modes. The intense bands at 1035, 1054, 1081, 1118 and 1154 cm(-1) are assigned to the ?3PO4(3-) antisymmetric stretching modes from both the HOP and tetrahedral [PO4] clusters. A set of Raman bands at 605, 613, 633 and 648 cm(-1) are assigned to the ?4 out of plane bending modes of the PO4, HPO4 and H2PO4 units. Raman bands observed at 414, 425, 460, and 479 cm(-1) are attributed to the ?2 tetrahedral PO4 clusters, HPO4 and H2PO4 bending modes. The intense Raman band at 3402 and the infrared band at 3403 cm(-1) are assigned to the stretching vibration of the OH units. A combination of Raman and infrared spectroscopy enabled aspects of the molecular structure of the mineral lazulite to be understood. PMID:23434550

Petrogenesis of fertile mantle peridotites from the Monte del Estado massif (southwest Puerto Rico): a preserved section of Proto-Caribbean oceanic lithospheric mantle?  

NASA Astrophysics Data System (ADS)

The Monte del Estado massif is the largest and northernmost serpentinized peridotite belt in southwest Puerto Rico. It is mainly composed of spinel lherzolite and minor harzburgite with variable clinopyroxene modal abundances. Mineral and whole rock major and trace element compositions of peridotites coincide with those of fertile abyssal peridotites from mid ocean ridges. Peridotites lost 2-14 wt% of relative MgO and variable amounts of CaO by serpentinization and seafloor weathering. HREE contents in whole rock indicate that the Monte del Estado peridotites are residues after low to moderate degrees (2-15%) of fractional partial melting in the spinel stability field. However, very low LREE/HREE and MREE/HREE in clinopyroxene cannot be explained by melting models of a spinel lherzolite source and support that the Monte del Estado peridotites experienced initial low fractional melting degrees (~ 4%) in the garnet stability field. The relative enrichment of LREE in whole rock is not due to secondary processes but probably reflects the capture of percolating melt fractions along grain boundaries or as microinclusions in minerals, or the presence of exotic micro-phases in the mineral assemblage. We propose that the Monte del Estado peridotite belt represents a section of ancient Proto-Caribbean (Atlantic) lithospheric mantle originated by seafloor spreading between North and South America in the Late Jurassic-Early Cretaceous. This portion of oceanic lithospheric mantle was subsequently trapped in the forearc region of the Greater Antilles paleo-island arc generated by the northward subduction of the Caribbean plate beneath the Proto-Caribbean ocean. Finally, the Monte del Estado peridotites belt was emplaced in the Early Cretaceous probably as result of the change in subduction polarity of the Greater Antilles paleo-island arc without having been significantly modified by subduction processes.

Estudio de la fotoabsorción y fotoionización de la molécula de alta relevancia atmosférica no a través de los estados Rydberg con la metodología MQDO  

NASA Astrophysics Data System (ADS)

Los procesos de fotoionización son de una importancia fundamental [1] y encuentran aplicación en un gran número de contextos científicos: Astrofísica [2], química de las radiaciones, biología. Los investigadores de dichos campos, necesitan de valores de fiables de secciones eficaces para la fotoionización parcial, la Fotoabsorción, así como para los procesos de fotofragmentación en amplios intervalos espectrales, particularmente en estudios de modelización [3-5]. En este trabajo se ha centrado la atención sobre el oxido nítrico, que se ha considerado apropiado y relevante por varios motivos: por el trascendental papel que representa en la física y química de la alta atmosfera [6], aparte de por estar íntimamente relacionado con los problemas de contaminación. Los procesos de recombinación disociativa [7] del NO, donde los estados Rydberg se encuentran directamente implicados, son relevantes, por ejemplo, en las regiones E y F de la ionosfera [7]. En este trabajo se estudia la fotoionización del NO desde el estado fundamental con la versión molecular del método del orbital de defecto cuántico (MQDO). Para ello se calcula el diferencial de las fuerzas de oscilador parciales que constituyen los canales de fotoionización del NO desde el estado fundamental. La continuidad del diferencial de fuerza de oscilador calculada a través del umbral de fotoionización, esto es, en las regiones del espectro discreta y del continua, se adopta como criterio de calidad la escasez de datos comparativos [8].

Records of environmental changes during the Holocene from Isla de los Estados (54.4°S), southeastern Tierra del Fuego  

NASA Astrophysics Data System (ADS)

Southernmost Patagonia, located at the relatively narrow passage between Antarctica and South America, is a highly sensitive region for recording meridional and zonal changes in the pattern of oceanic and atmospheric circulation. The island of Isla de los Estados, situated at 54.5°S, 64°W, east of Argentinean Tierra del Fuego, provides an exceptional possibility, to investigate terrestrial records of atmospheric conditions in an oceanic setting during the last deglaciation and the Holocene. Here we present geochemical and diatom analyses from 10 600 to c. 1500 cal BP of one sequence (LGB) with peat, lake sediments and lagoon deposits at the northern coast of the island, and a lake sediment sequence (CAS) 3 km further inland. The data comprise TC, TN, loss on ignition analyses and continuous XRF scanning as well as age-depth modeling based on AMS- 14C dating on both cores. Diatom analysis of the CAS record complements the geochemical proxies. During the Holocene, our two sites have been impacted by two different forcings: changes in the regional climate regime largely influenced by the varying strength and position of the Southern Hemisphere Westerlies (SHW), while relative sea-level changes affected the deposits of the coastal site. In concert with the onset of the Antarctic thermal optimum, our data suggest fairly warm conditions and the establishment of denser peat and forest vegetation on the island c. 10 600 cal BP. Between 8500 and 4500 cal BP geochemistry and diatoms from the CAS record indicate stronger Westerlies at this latitude, which means higher wind speed or higher storm frequency and more precipitation, resulting in more pronounced surface run-off. After 4500 cal BP, the geochemical proxies and large changes in diatom assemblages indicate a decrease in precipitation, weaker winds and possibly cooler conditions, probably as an effect of weaker SHW and/or a latitudinal shift. The depositional environment of CAS changed from gyttja to peat around 1000 cal BP. At LGB, the onset of gyttja sedimentation around 7900 cal BP shows that the former wet land with peat accumulation had become a lake with a fairly rapid sedimentation. The chemical data from LGB imply a gradually increasing marine influence, probably as an effect of both rising sea level and increased impact of storms and maximum high tides. After a marine high-stand during the mid-Holocene, the LGB site returned into a peat bog again around 3400 cal BP. Our data suggest that since then relative sea level first dropped back below present sea level followed by a rise to present day sea level.

Multi-proxy analyses of a peat bog on Isla de los Estados, easternmost Tierra del Fuego: a unique record of the variable Southern Hemisphere Westerlies since the last deglaciation  

NASA Astrophysics Data System (ADS)

We have analyzed an almost 14,000 year old peat sequence on the island of Isla de los Estados (55° S, 64° W), east of Tierra del Fuego, in the core of the Southern Hemisphere Westerlies. A multitude of methods have been used: high resolution 14C dating; detailed lithologic descriptions including humification degree; loss on ignition; magnetic susceptibility; bulk density; pollen and spore analysis and determination of Aeolian sand influx. By combining proxies for wind and precipitation we have been able to reconstruct how the westerlies have varied over time in the Atlantic sector of the Southern Ocean. It shows that this westerly wind belt was most intense at the onset of the record, 13,600-13,200 cal BP, coinciding with the mid to late part of the Antarctic Cold Reversal, followed by a gradual decline. At 12,200 cal BP the westerlies seem to have shifted to a position south of Tierra del Fuego and this phase, the calmest and driest period on the island throughout the sequence, ended at 10,000 cal BP when the westerlies moved equatorward again. Since then the westerlies have been present but with a variable impact on the 55° S latitude of the Atlantic. Mostly conditions have been fairly similar to today, but occasionally with a wider or narrower and/or weaker or stronger wind belt. At 7200 cal BP wind intensity began to increase and between 4500 and 3500 cal BP these southern latitudes experienced a distinct wind and precipitation maximum, both in terms of perseverance and intensity. Our results show a both wide and strong wind belt, with possible niveo-aeolian activity in Tierra del Fuego in winter, and possibly creating milder summers around the Antarctic Peninsula. In the later part of the Holocene, expansion-contraction phases of the wind belt, especially in winter, seem to have been a common phenomenon.

Desde el descubrimiento de fuertes excesos infrarrojos en ? Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. ? Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a ?Pic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en ? Pic indica edades avanzadas para ? Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para ? Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Feeding behavior of Triatoma vitticeps (Reduviidae: Triatominae) in the state of Minas Gerais, Brazil.  


The objective of this study was to evaluate the feeding behavior of Triatoma vitticeps through the identification of its food sources and the characterization of the blood ingestion process. In addition, we aimed to verify if the saliva of this vector interferes with the perception of the host during the feedings by creating a nervous impulse. Here, we demonstrated that the T. vitticeps saliva reduces, gradually and irreversibly, the amplitude of the compound action potential of the nervous fibre, which helps decrease the perception of the insect by the host. The precipitin reaction demonstrated the feeding eclecticism of this vector, with the identification of eight food sources - most of them found simultaneously in the same insect. The analysis of the electrical signals produced by the cibarial pump during meals demonstrated that the best feeding performance of T. vitticeps nymphs that fed on pigeons is mainly due to the higher contraction frequency of the pump. The longer contact period with the host to obtain a complete meal compared with other triatominae species of the same instar could favor the occurrence of multiple blood sources in T. vitticeps under natural conditions, as it was evidenced by the precipitin test.

Possible competitive displacement of planorbids by Melanoides tuberculata in Minas Gerais, Brazil.  


Several species of snails, including Pomacea haustrum, Marisa cornuarietis and Helisoma duryi, have been identified as probable competitors and/or predators of planorbid intermediate hosts of Schistosoma. During the last few years, studies carried out in the Caribbean region have shown reductions and even disappearances of populations of Biomphalaria glabrata and B. straminea in breeding places where the snail Melanoides tuberculata was introduced. Observations made over a period of 10 years in two lakes close to Belo Horizonte, MG, showed that there were marked reductions in autochthonous populations of B. glabrata and B. straminea after the arrival of M. tuberculata, both Biomphalaria species disappearing completely after eight years.

Challenges of Including the Mina Route in the Nevada Rail Alignment Environmental Impact Statement  

SciTech Connect

The Department of Energy's Office of Civilian Radioactive Waste Management is developing the Yucca Mountain repository for the disposition of spent nuclear fuel (SNF) and high level radioactive waste (HLW). Part of that development is the transportation infrastructure needed to ship SNF and HLW from 77 sites around the country to the repository. A Record of Decision was issued in 2004 to use mostly rail as the mode of transport both nationally, and in the State of Nevada. No rail access exists to the Yucca Mountain site, so a Rail Alignment Environmental Impact Statement (RA-EIS) is being prepared to address the impacts associated with connecting existing track in Nevada to Yucca Mountain. Late in the preparation of the Draft RA-EIS, an option to consider an additional alignment alternative was introduced. This paper describes the consideration given to the new alternative and describes how it is being incorporated into the RA-EIS. (authors)

Antimicrobial resistance and virulence profiles of salmonella isolated from butcher shops in minas gerais, Brazil.  


Salmonella can contaminate finished products of butcher shops, mainly through cross-contamination of utensils exposed to raw materials. To identify the main sources of contamination with this foodborne pathogen in four butcher shop environments, surface samples were obtained from employees' hands, cutting boards, knives, floor of the refrigeration room, meat grinders, and meat tenderizers (32 samples per area) and analyzed for Salmonella using the International Organization for Standardization method 6579, with modifications. Suspect isolates were identified by PCR (targeting ompC), and confirmed Salmonella isolates were subjected to pulsed-field gel electrophoresis (after treatment with restriction enzyme XbaI), analyzed for the presence of virulence genes (invA, sefA, and spvC), and screened for resistance to 12 antimicrobials. Salmonella isolates was identified only on cutting boards (five samples) from three butcher shops. Fifteen isolates were confirmed as Salmonella belonging to four pulse types (similarity of 71.1 to 100%). The invA gene was detected in 13 isolates, and the sefA was found in 8 isolates; no isolate carried spvC. All tested isolates were resistant to clindamycin and sensitive to amikacin and cefotaxine, and all isolates were resistant to at least 3 of the 12 antimicrobials tested. The results indicate the importance of cutting boards as a source of Salmonella contamination in butcher shops. The presence of multidrug-resistant Salmonella strains possessing virulence genes highlights the health risks for consumers. PMID:23992511

Audiomagnetotelluric 3D imaging of the Regis kimberlite pipe, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Kimberlite pipes are significant source rocks that form primary diamond deposits. Usually, the low resistivity of kimberlite produces a significant contrast in electrical resistivity, which can be mapped using electromagnetic EM methods. The Regis kimberlite is located in a well-known diamondiferous province in central Brazil. The main tectonic feature of the area is a northwest-southeast major crustal fracture zone that extends for more than 3000 km within the Brazilian territory, where Regis and several other kimberlites have intruded. In this paper, we present an audiomagnetotelluric (AMT) study at the Regis pipe. AMT data were collected in the 10 Hz-100 kHz frequency range at 111 stations on a grid, and three-dimensional (3D) inversions were used to generate a resistivity model of the pipe. Our interpretation was corroborated by available geological information of six drill holes. The final model shows an asymmetric conically shaped body with a conductivity range of 2 to 70 ohm.m and a depth of 0 to 550 m. These conductive sources were associated with crater lake sediments in the upper part and the main kimberlite diatreme at depth.

Characterization of Mina?u virus (Reoviridae: Orbivirus) and pathological changes in experimentally infected newborn mice  

PubMed Central

Minaçu virus was isolated from Ochlerotatus scapularis (Diptera: Culicidae) in Minaçu, Goiás State, Brazil, in 1996. In attempting characterization of virus serological (hemagluttination inhibition, HI; indirect immunofluorescence assay, IFA), physicochemical [test for deoxycholate acid (DCA) sensitivity; polyacrylamide gel electrophoresis (PAGE)] tests and ultrastructural studies were made. Virus was also assayed in suckling mice after intracerebral inoculation of 0.02 ml and in VERO and C6/36 cells with 0.1 ml of viral suspension containing 105 LD50/ml. Inoculated and control systems were observed daily. Every 24 h, one control and two inoculated animals were killed for tissue testing, including histopathological changes by haematoxylin and eosin (HE)-stained sections, which were semi-quantified. Research into viral antigen in the tissues of mice [central nervous system (CNS), liver, heart, lungs, spleen and kidneys] was carried out by the immunohistochemical technique using the peroxidase system. The virus only replicated in VERO cells, with antigen positive by IFA. Positive complement fixation tests were only obtained using antiserum of Minaçu virus. Minaçu virus is DCA resistant; haemagglutinating activity was negative. By electronic microscopy non-enveloped virus particles were 75 nm in diameter. PAGE analysis showed Minaçu virus genome profile with 10 RNA segments. Infected, non-killed animals died 7 days after inoculation. Tissue lesions were observed in all organs, except the lungs. Intense lesions were observed in the CNS and the heart, where neurone and cardiocyte necroses, respectively, were noted. The liver, spleen and kidneys had moderate tissue changes. Viral antigens were more abundant in the CNS and the heart, and absent in the lungs. In conclusion, Minaçu virus belongs to the family Reoviridae, genus Orbivirus.

This study was developed in the urban area of Governador Valadares, a reemerging focus of intense transmission of visceral leishmaniasis (VL) in Brazil, presenting 86 human cases of VL from 2008 to 2011. The disease prevailed in males (73.2%) with most patients between 0 and 9 years (44.1%) and a lethality rate of 16.2%. A canine survey was carried out on 16,529 domestic dogs in 35 districts in the area and it showed that 30.2% of them (4,992?dogs) were positive for VL by serum assays. Prevalence ratios for canine VL varied between 13.6% and 53.4%. The clinical exam of 343 seropositive dogs showed that 49.9% of them were considered symptomatic, with larger prevalence of canine VL being in short-furred animals (90%). The entomological survey was performed in eight districts, where 2,539 phlebotomines were captured, preferentially in the peridomicile (84.5%). Lutzomyia longipalpis was the predominant species (90%) suggesting its participation in the VL transmission in the area. The correlation between canine prevalence and L. longipalpis density was evaluated.

Gold in Archean iron formations at the nova lima district, and in the Quadrilatero Ferrifero, Minas Gerais, Brazil  

SciTech Connect

Gold is in iron formation and metachert of the Rio das Velhas Greenstone Belt which underwent three main periods of deformation and is greenschist facies. At the Morro Velho, Bicalho, Bela Fama, and Urubu mines gold is mostly within and at grain boundaries of pyrrhotite, arsenopyrite, pyrite, minor chalcopyrite, cubanite, tetrahedrite, galena and sphalerite, in stratiform and stratabound massive and banded sulfide bodies. Some gold is in minor quartz veins. The main host rock consist of schistose to massive quartz ferroan dolomite and ankerite and it rests on spilitized tholeiitic metabasalt with intercalcated mafic to felsic metatuffs overlain by intermediate to felsic metatuffs. /sup 18/O of authigenic quartz of 17.07 per thousand is similar to that of Archean marine carbonate-bearing chert. At the Raposos, Faria, Cuiaba, Sao Bento and Santa Quiteria mines gold is with sulfide minerals similar to those at Morro Velho Mine but is in banded, cabonate, silicate, oxide and sulfide facies iron formation conformable upon and lateral to carbonate rock which both overlies and is intercalated with spilitized pillowed metabasalt, felsic metatuffs and graphitic phyllite. Both gold bearing-sections have a base of metamorphosed periodtitic komatiite and basalt and clastic rocks. The gold-bearing sulfide bodies, the carbonate rock and the BIF are interpreted as chemical precipitants on the sea floor by mixing of ascending reduced hot aqueous fluids and sea water.

Seasonal dynamics of the free-living phase of Anocentor nitens at Pedro Leopoldo, Minas Gerais, Brazil.  


An understanding of seasonal dynamics in the free-living phase of the tropical horse tick, Anocentor nitens, is vital for effective control measures. This study examines seasonal changes in the oviposition and incubation periods, eclosion rates, reproductive success, and larval survival in the free-living phase during the period June 1995-July 1997. Ten engorged female ticks, placed individually in wire-gauze tubes, were exposed in a field of Brachiaria decumbens fortnightly each month, and monitored to measure the duration of the various reproductive parameters, and success. Larval abundance was estimated indirectly, through the percentage of females with viable progeny, and directly by using a flagging method. Duration of the free-living cycle ranged from 12.3 weeks (October and December) to 23.5 weeks (March). The cycle was prolonged in cold and dry months. Larval survival was longer from February to July, and reduced from August to February. Oviposition was recorded in all months, and the egg production index ranged from 26.7 to 47.1%. The eclosion rate ranged from 0.1 to 76.6% in different months. Monthly estimates of larval abundance in the pasture were similar for the two methods used, being higher in months with higher temperatures, relative humidity and rainfall. PMID:10628702

Denudation rates of the Southern Espinhaço Range, Minas Gerais, Brazil, determined by in situ-produced cosmogenic beryllium-10  

NASA Astrophysics Data System (ADS)

To investigate denudation rates in the southern part of the Espinhaço Range (central-eastern Brazil) and to understand how this important resistant and residual relief has evolved in the past 1.38 My, cosmogenic 10Be concentrations produced in situ were measured in alluvial sediments from the three main regional basins, whose substratum is composed primarily of quartzites. The long-term denudation rates (up to 1.38 My) estimated from these measurements were compared with those that affect the western (São Francisco River) and eastern (Doce and Jequitinhonha Rivers) basins, which face the West San Francisco craton and the Atlantic, respectively. Denudation rates were measured in 27 samples collected in catchments of different sizes (6–970 km2) and were compared with geomorphic parameters. The mean denudation rates determined in the northern part are low and similar to those determined in the southern part, despite slightly different geomorphic parameter values (catchment relief and mean slope). For the southern catchments, the values are 4.91 ± 1.01 m My? 1 and 3.65 ± 1.26 m My? 1 for the Doce and São Francisco River basins, respectively; for the northern catchments, they are 4.40 ± 1.06 m My? 1 and 3.96 ± 0.91 m My? 1 for the Jequitinhonha and São Francisco River basins, respectively. These low values of denudation rates suggest no direct correlation if plotted against geomorphic parameters such as the catchment area, maximum elevation, catchment relief, average relief and mean slope gradients. These values show that the regional landscape evolves slowly and is strongly controlled by resistant lithology, with similar erosional rates in the three studied basins.

Prevalence of yeasts and mycelial fungi in bovine parasitic otitis in the State of Minas Gerais, Brazil.  


Infestations by rhabditiform nematodes and acarids of the genus Raillietia are considered the primary causes of external otitis in cattle in tropical regions. Recently, yeasts of the genus Malassezia have been associated with a relatively high percentage of otitis cases, but the occurrence of other yeasts and mycelial fungi has not yet been reported in the literature. This work studied the presence of fungi in the ear canal of 45 cattle with external parasitic otitis. The results were positive for yeasts of the genus Malassezia in 31 (68.9%) of the 45 cultures in Mycosel medium supplemented with olive oil. The 45 cultures in Sabouraud dextrose medium revealed the growth of seven (15.5%) yeasts of the genus Candida, five (11.1%) Rhodotorula mucilaginosa, two (4.4%) fungi of the genus Aspergillus and eight 'Micelia sterilia'. Future studies may confirm and elucidate the importance of these agents in the aetiology of bovine otitis. PMID:11708682

Natural Leishmania sp. reservoirs and phlebotomine sandfly food source identification in Ibitipoca State Park, Minas Gerais, Brazil.  


Leishmania spp are distributed throughout the world and different species are associated with varying degrees of disease severity. However, leishmaniasis is thought to be confined to areas of the world where its insect vectors, sandflies, are present. Phlebotomine sandflies obtain blood meals from a variety of wild and domestic animals and sometimes from humans. These vectors transmit Leishmania spp, the aetiological agent of leishmaniasis. Identification of sandfly blood meals has generally been performed using serological methods, although a few studies have used molecular procedures in artificially fed insects. In this study, cytochrome b gene (cytB) polymerase chain reaction (PCR) was performed in DNA samples isolated from 38 engorged Psychodopygus lloydi and the expected 359 bp fragment was identified from all of the samples. The amplified product was digested using restriction enzymes and analysed for restriction fragment length polymorphisms (RFLPs). We identified food sources for 23 females; 34.8% yielded a primate-specific banding profile and 26.1% and 39.1% showed banding patterns specific to birds or mixed restriction profiles (rodent/marsupial, human/bird, rodent/marsupial/human), respectively. The food sources of 15 flies could not be identified. Two female P. lloydi were determined to be infected by Leishmania using internal transcribed spacer 1 and heat shock protein 70 kDa PCR-RFLP. The two female sandflies, both of which fed on rodents/marsupials, were further characterised as infected with Leishmania (Viannia) braziliensis. These results constitute an important step towards applying methodologies based on cytB amplification as a tool for identifying the food sources of female sandflies. PMID:22666858

Detection of toxins A/B and isolation of Clostridium difficile and Clostridium perfringens from dogs in Minas Gerais, Brazil  

PubMed Central

The objective of this study was to detect C. difficile A/B toxins and to isolate strains of C. perfringens and C. difficile from diarrheic and non-diarrheic dogs in Brazil. Stool samples were collected from 57 dogs, 35 of which were apparently healthy, and 22 of which were diarrheic. C. difficile A/B toxins were detected by ELISA, and C. perfringens and C. difficile were identified by multiplex PCR. C. difficile A/B toxins were detected in 21 samples (36.8%). Of these, 16 (76.2%) were from diarrheic dogs, and five (23.8%) were from non-diarrheic dogs. Twelve C. difficile strains (21.1%) were isolated, of which ten were A+B+ and two were A?B?. All non-toxigenic strains were isolated from non-diarrheic animals. The binary toxin gene cdtB was found in one strain, which was A+B+ and was derived from a non-diarrheic dog. C. perfringens strains were isolated from 40 samples (70.2%). Of these, 18 (45%) were from the diarrheic group, and 22 (55%) belonged to the non-diarrheic group. All isolates were classified as C. perfringens type A and there was an association between the detection of the cpe gene and the presence of diarrhea. Interestingly, ten strains (25%) were positive for the presence of the cpb2 gene. The high rate of detection of the A/B toxins in non-diarrheic dogs suggests the occurrence of subclinical disease in dogs or carriage of its toxins without disease. More studies are needed to elucidate the epidemiology of C. difficile and C. perfringens in dogs and to better our understanding of C. difficile as a zoonotic agent. This is the first study to report the binary toxin gene in C. difficile strains isolated from dogs in Brazil.

[Dipterans of forensic interest in two vegetation profiles of cerrado in Uberlândia, State of Minas Gerais, Brazil].  


Carrion breeding insects may be of great utility in crimes briefing. Studies on forensic entomology are restricted to few localities in Brazil and very few of them were done in the cerrado vegetation (a type of Savannah) until now. This work aimed to survey the main species of dipterans associated with the decomposition process of Sus scrofa and the insect succession pattern in carcasses in the Cerrado. The study was carried out in the dry and humid season of the year, in two cerrado vegetation profiles in Uberlândia, MG. Two pig carcasses were placed in each vegetation profile and time period of the year. The decomposition process was slower and insects were more abundant in the dry season. Differences in temperature, air humidity and pluvial precipitation seemed to be the main physical factors responsible for the differences in the time of decomposition of the pig carcasses between the two seasons. Fourteen species of dipterans (59,467 specimens) bred in the decomposing carcasses. Chrysomya albiceps (Wiedemann) was the species more abundantly breed in the two periods. The other species that breed in the carcasses were: C. putoria (Wiedemann), Hemilucilia segmentaria(Fabricius), Lucilia eximia(Wiedemann) (Calliphoridae), Peckia (Pattonella) intermutans(Walker), Peckia (Squamatoides) trivitatta(Curran), Sarcodexia lambens(Wiedemann) (Sarcophagidae), Musca domestica(L.), Ophyra aenescens(Wiedemann), Stomoxys calcitransL. (Muscidae), Fannia pusio(Wiedemann), Fannia sp. (Fanniidae), Hermetia illuscens L. (Stratiomyidae) and Phoridae sp. The Cerrado of this region presents many dipterans potential forensic indicators.

A new approach to characterization of the resistance of populations of Rhipicephalus microplus (Acari: Ixodidae) to organophosphate and pyrethroid in the state of Minas Gerais, Brazil.  


The monitoring of resistance of cattle tick populations in Brazil to the chemical bases in use is largely limited to investigation of the phenotypic profile. There are few studies investigating the role played by the genotypic profile in acaricide resistance in the country. Therefore, the aim of the present study was to carry out molecular characterization and trace out the genetic profile of populations of Rhipicephalus microplus with respect to resistance to the organophosphate and pyrethroid chemical groups. For that purpose, larvae were genotyped belonging to 587 populations for pyrethroids and 306 for organophosphates, using the polymerase chain reaction technique. It was found that 75.49% and 97.44% of the larvae studied showed resistance to the organophosphates and pyrethroids, respectively. Among the populations resistant to pyrethroids, 91.9% were heterozygotes, showing that most of the resistant populations have only one allele responsible for resistance. Therefore, it is possible to conclude that the genotyped populations have high resistance to organophosphates, and even more so to pyrethroids. This information is fundamental for understanding the mechanisms of resistance of R. microplus to acaricides, to enable improvement of control techniques. PMID:23639866

Hourly Activity and Natural Infection of Sandflies (Diptera: Psychodidae) Captured from the Aphotic Zone of a Cave, Minas Gerais State, Brazil  

PubMed Central

Sandflies are holometabolous insects that are of great epidemiological importance in the neotropical region as vectors of leishmaniases. Caves are ecotopes that significantly differ from external environments and, among the insects that live or visit their internal area and adjacent environment, sandflies are commonly found. Based on this context, the objective of this work was to examine the period of activity of sandflies in the cave environment in the aphotic zone. Thus, four sandfly captures were conducted, one in each season of the year, in a cave where studies on the bioecological aspects of sandfly fauna have been conducted since 2008. In this same study, we have also noticed the presence of flagellates in some captured females. Catches were carried out for 24 hours using a Shannon trap, light bait, and cave walls were actively searched. We collected a total of 638 sandflies, representing 11 species. The most abundant species and with more intense period of activity were, in descending order: Lu. cavernicola (62%), Ev. spelunca (16%) and Ev. sallesi (14%). A total of 69 females were dissected to check for natural infection, and in five specimens we found living flagellated forms: two Ev. spelunca, two Ev. sallesi and one Sc. sordellii. This study shows that the activity of some species caught in the aphotic zone of the cave, especially Lu. cavernicola, differs from what has already been reported in previous sandfly captures, which are almost always conducted at night and during twilight. The existence of sandflies that were naturally infected with flagellates and the lack of awareness regarding the behaviour of sandflies in cave environments are strong indicators of the need for further study on this group of insects in this ecotope, as a safety measure to protect the visitors of such environment.

Hydrothermal fluid source constrained by Co/Ni ratios in coexisting arsenopyrite and tourmaline: the auriferous lode of Passagem, Quadrilátero Ferrífero of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The auriferous lode of Passagem de Mariana is characterised by abundant tourmaline, which is intergrown with arsenopyrite. Spot measurements using laser ablation-inductively coupled plasma-mass spectrometry show that Co and Ni are the most abundant trace elements in the arsenopyrite (45-538 ppm Co, 246-828 ppm Ni), with Co/Ni ratios consistently <1. The coexisting tourmaline also has Co/Ni <1, with Co and Ni contents that are ~2 orders of magnitude lower than those in the arsenopyrite. The Co/Ni ratios of tourmaline and arsenopyrite are tightly distributed along a positive linear trend, the angular coefficient of which represents the Co/Ni of the hydrothermal fluid from which these minerals precipitated. The fluid Co/Ni ratio is close to the average Co/Ni value for the upper continental crust. In conjunction with the abundance of lode tourmaline and its B-isotope data (from the literature), the Co/Ni ratios of tourmaline and arsenopyrite fingerprint a continental evaporitic source of B.

Using oxygen isotope chemistry to track hydrothermal processes and fluid sources in itabirite-hosted iron ore deposits in the Quadrilátero Ferrífero, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The Quadrilátero Ferrífero, Brazil, is presently the largest accumulation of single itabirite-hosted iron ore bodies worldwide. Detailed petrography of selected hypogene high-grade iron ore bodies at, e.g. the Águas Claras, Conceição, Pau Branco and Pico deposits revealed different iron oxide generations, from oldest to youngest: magnetite ? martite (hematite pseudomorph after magnetite) ? granoblastic (recrystallised) ? microplaty (fine-grained, <100 ?m) ? specular (coarse-grained, >100 ?m) hematite. Laser-fluorination oxygen isotope analyses of selected iron ore species showed that the ?18O composition of ore-hosted martite ranges between -4.4 and 0.9 ‰ and is up to 11 ‰ depleted in 18O relative to hematite of the host itabirite. During the modification of iron ore and the formation of new iron oxide generations (e.g. microplaty and specular hematite), an increase of up to 8 ‰ in ?18O values is recorded. Calculated ?18O values of hydrothermal fluids in equilibrium with the iron oxide species indicate: (1) the involvement of isotopically light fluids (e.g. meteoric water or brines) during the upgrade from itabirite-hosted hematite to high-grade iron ore-hosted martite and (2) a minor positive shift in ?18Ofluid values from martite to specular hematite as result of modified meteoric water or brines with slightly elevated ?18O values and/or the infiltration of small volumes of isotopically heavy (metamorphic and/or magmatic) fluids into the iron ore system. The circulation of large fluid volumes that cause the systematic decrease of 18O/16O ratios from itabirite to high-grade iron ore requires the presence of, e.g. extensive faults and/or large-scale folds.

Ground water chemistry and geochemical modeling of water-rock interactions at the Osamu Utsumi mine and the Morro do Ferro analogue study sites, Poc??os de Caldas, Minas Gerais, Brazil  

USGS Publications Warehouse

Surface and ground waters, collected over a period of three years from the Osamu Utsumi uranium mine and the Morro do Ferro thorium/rare-earth element (Th/REE) deposits, were analyzed and interpreted to identify the major hydrogeochemical processes. These results provided information on the current geochemical evolution of ground waters for two study sites within the Poc??os de Caldas Natural Analogue Project. The ground waters are a KFeSO4F type, a highly unusual composition related to intense weathering of a hydrothermally altered and mineralized complex of phonolites. Tritium and stable isotope data indicate that ground waters are of meteoric origin and are not affected significantly by evaporation or water-rock interactions. Recharging ground waters at both study sites demonstrate water of less than about 35 years in age, whereas deeper, more evolved ground waters are below 1 TU but still contain in most cases detectable tritium. These deeper ground waters may be interpreted as being of 35 to 60 or more years in age, resulting mainly from an admixture of younger with older ground waters and/or indicating the influence of subsurface produced tritium. Geochemical processes involving water-rock-gas interactions have been modeled using ground water compositions, mineralogic data, ion plots and computations of speciation, non-thermodynamic mass balance and thermodynamic mass transfer. The geochemical reaction models can reproduce the water chemistry and mineral occurrences and they were validated by comparing the results of thermodynamic mass transfer calculations (using the PHREEQE program, Parkhurst et al., 1980). The results from the geochemical reaction models reveal that the dominant processes are production of CO2 in the soil zone through aerobic decay of organic matter, dissolution of fluorite, calcite, K-feldspar, albite, chlorite and manganese oxides, oxidation of pyrite and sphalerite, and precipitation of ferric oxides, silica and kaolinite. Gibbsite precipitation can be modeled for the shallow (recharge) water chemistry at Morro do Ferro, consistent with known mineralogy. Recharge waters are undersaturated with respect to barite and discharging waters and deeper ground waters are saturated to supersaturated with respect to barite demonstrating a strong solubility control. Strontium isotope data demonstrate that sources other than calcium-bearing minerals are required to account for the dissolved strontium in the ground waters. These may include K-feldspar, smectite-chlorite mixed-layer clays and goyazite [SrAl3(PO4)2(OH)5??H2O]. ?? 1992.

Tidally-induced sediment transport patterns in the upper Bay of Fundy: A numerical study  

NASA Astrophysics Data System (ADS)

The Minas Basin, the eastern end of the Bay of Fundy, is well known for its high tide ranges and strong tidal currents, which can be exploited to extract electricity power. The properties of the tidally-induced sediment transport in the Minas Basin, where significant changes in tidal processes may occur due to a recently proposed tidal power project, have been studied with a three-dimensional hydrodynamic model, an empirical bed load sediment transport model and surface sediment concentrations derived from the remotely-sensed images. The hydrodynamic model was evaluated against independent observational data, which include tidal elevation, tidal current (in the full water column and bottom layer), residual current profile and tidal asymmetry indicators. The evaluation shows that the model is in good agreement with the observations.The sediment transport includes two components, bed load and suspended particulate load. The bed load is calculated using the modelled bottom shear stress and the observed grain size data. The estimated features of bed load transport roughly agree with the observed patterns of the erosion and deposition in the Minas Basin and Cobequid Bay. The transport of the suspended load is estimated using the modelled velocity fields and the surface sediment concentration derived from remote-sensing images. The comparisons between the modelled results and the limited observations illustrate that the observed directions of suspended sediment transport are basically reproduced by the model. The modelled net suspended sediment input into the Minas Basin through Minas Passage is 2.4×106 m3 yr-1, which is comparable to the observed value of 1.6×106 m3 yr-1.The variations of the bed load and the suspended load in space and time are also presented. The total net transport, defined as the mean value of the sum of bed and suspended load transports during the tidal cycle, shows strong spatial variability. The magnitude of the transport flux ranges from 0.1 to 0.2 kg m-1 s-1 in Minas Channel and Minas Passage, 0.1 kg m-1 s-1 in Cobequid Bay, to 0.01 kg m-1 s-1 in the central Minas Basin and Southern Bight. In Minas Channel, the sediment transport follows the structure of the tidal residual circulation, which features a large anticlockwise gyre. The sediment in Minas Passage moves eastward and deposits into the central Minas Basin. However, the sediment from the eastern part of the Basin moves westward and deposits in the central Minas Basin as well. In the Cobequid Bay, sediment moves eastward and deposits in the upper bay.

Factors influencing tropical island freshwater fishes:Species, status, and management implications in puerto rico [Factores que influencian a los peces tropicales de agua dulce: Especies, estado actual e implicaciones para el manejo en Puerto Rico  

USGS Publications Warehouse

Anthropogenic effects including river regulation, watershed development, contamination, and fish introductions have substantially affected the majority of freshwater habitats in Europe and North America. This pattern of resource development and degradation is widespread in the tropics, and often little is known about the resources before they are lost. This article describes the freshwater resources of Puerto Rico and identifies factors that threaten conservation of native fishes. The fishes found in freshwater habitats of Puerto Rico represent a moderately diverse assemblage composed of 14 orders, 29 families, and 82 species. There are fewer than 10 species of native peripherally-freshwater fish that require a link to marine systems. Introductions of nonindigenous species have greatly expanded fish diversity in freshwater systems, and native estuarine and marine species (18 families) also commonly enter lowland rivers and brackish lagoons. Environmental alterations, including land use and development, stream channelization, pollution, and the impoundment of rivers, combined with nonnative species introductions threaten the health and sustainability of aquatic resources in Puerto Rico. Six principal areas for attention that are important influences on the current and future status of the freshwater fish resources of Puerto Rico are identified and discussed.

Genotype by environment interaction in Nelore cattle from five Brazilian states  

PubMed Central

Records from 75,941 Nelore cattle were used to determine the importance of genotype by environment interaction (GEI) in five Brazilian states. (Co)variance components were estimated by single-trait analysis (with yearling weight, W450, considered to be the same trait in all states) and multiple-trait analysis (with the record from each state considered to be a different trait). The direct heritability estimates for yearling weight were 0.51, 0.39, 0.44, 0.37 and 0.41 in the states of Goiás, Mato Grosso, São Paulo, Mato Grosso do Sul and Minas Gerais, respectively. The across-state genetic correlation estimates between Goiás and Mato Grosso, Goiás and Minas Gerais, São Paulo and Minas Gerais, and Mato Grosso do Sul and Minas Gerais ranged from 0.67 to 0.75. These estimates indicate that GEIs are biologically important. No interactions were observed between Goiás and São Paulo, Goiás and Mato Grosso do Sul, Mato Grosso and São Paulo, Mato Grosso and Mato Grosso do Sul, Mato Grosso and Minas Gerais, or São Paulo and Mato Grosso do Sul (0.82 to 0.97). Comparison of single and multiple-trait analyses showed that selection based on the former was less efficient in the presence of GEI, with substantial losses (up to 10%) during selection.

We studied the yeast communities associated with fruits, mushrooms, tree exudates, and flies of the genus Drosophila, in two Atlantic Rain Forest fragments in state of Minas Gerais, Brazil. A total of 456 samples were collected from Rio Doce State Park and 142 from Ecological Station of Universidade Federal de Minas Gerais. From these samples, 608 yeast isolates were obtained, belonging to 71 different species. Among the yeasts isolated from Rio Doce State Park, 17 isolates were recovered from fruits, 12 from mushrooms, 13 from tree exudates, and 299 from Drosophila spp. In the Ecological Station of Universidade Federal de Minas Gerais, 24 isolates were recovered from fruits and 243 from Drosophila spp. Distinct communities of yeast were observed in Drosophila flies, fruits, mushrooms and tree exudates. The highest number of yeast species was recovered from Drosophila flies suggesting that flies are the natural vectors of these microorganisms.

Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) (Diptera: Psychodidae: Phlebotominae) geographical distribution and epidemiological importance.  


Nyssomyia intermedia (Lutz & Neiva 1912) and N. neivai (Pinto 1926) are possible vectors of tegumentary leishmaniasis in some regions of Brazil. Further, the latter was until recently, considered a junior synonym of the former. This study has the purpose of updating our knowledge of the geographical distribution of these species, based on specimens deposited at the collection of the Centro de Pesquisas René Rachou-Fiocruz, Faculdade de Saúde Pública-Universidade de São Paulo, and on data presented by literature as also to associate this distribution with the cutaneous leishmaniasis cases reported. It has been reported that N. intermedia occurs in the states of the Northeastern Region, in Rio de Janeiro, Espírito Santo, on the northern coast of São Paulo, in eastern Minas Gerais, Mato Grosso do Sul, and Goiás, close to the border with Minas Gerais and Bahia. N. neivai occurs in the Southern Region, southern coast and in western São Paulo, southern and western Minas Gerais, southern Goiás, and southern Pará, beyond Argentina, Bolivia, and Paraguay. It is important to highlight that N. intermedia and N. neivai occur in sympatry in Minas Gerais and São Paulo. N. intermedia or N. neivai are predominant or are captured abundantly in several cutaneous leishmaniasis foci in the Southeastern and Southern regions of Brazil. PMID:17612769

In spite of the increasing number of traitsbased analyses of freshwater fishes in the United States, no consolidated database of traits of this group exists publicly, and much useful information on these species is documented only in obscure sources. The largely inaccessible and unconsolidated traits information makes large-scale analysis involving many fishes and/or traits particularly challenging. We have compiled a database of > 100 traits for 809 (731 native and 78 nonnative) fish species found in freshwaters of the conterminous United States, including 37 native families and 145 native genera. The database, named FishTraits, contains information on four major categories of traits: (1) trophic ecology; (2) body size, reproductive ecology, and life history; (3) habitat preferences; and (4) salinity and temperature tolerances. Information on geographic distribution and conservation status was also compiled. The database enhances many opportunities for conducting research on fish species traits and constitutes the first step toward establishing a central repository for a continually expanding set of traits of North American fishes.

Establishment of Tunga trimamillata (Siphonaptera: Tungidae) in Brazil.  


Tunga trimamillata is a species of sand flea occurring in Ecuador and Peru parasitizing cattle, goat, sheep, swine, and man. This is the first report of this species in Brazil, having been found on the hooves of cows in Barretos, São Paulo State, and Felixlândia, Minas Gerais State, and previously misidentified as Tunga penetrans. A previous report concerning Hydrochoerus hydrochaeris from Rio Novo, Minas Gerais State, may also be attributed to that species of sand flea, a possible the primary host. Given the large geographical distribution of T. trimamillata, the vast cattle population in Brazil, and the high number of individuals subject to the risk of tungiasis, the number of cases attributed to this sand flea will most likely increase over time.

New data on freshwater psammic Gastrotricha from Brazil  

PubMed Central

Abstract Current knowledge of freshwater gastrotrich fauna from Brazil is underestimated as only two studies are available. The present communication is a taxonomic account of the first-ever survey of freshwater Gastrotricha in Minas Gerais State. Samplings were carried out yielding six species of three Chaetonotidae genera: Aspidiophorus cf. pleustonicus, Ichthydium cf. chaetiferum, Chaetonotus acanthocephalus, Chaetonotus heideri, Chaetonotus cf. succinctus, Chaetonotus sp., and also an undescribed species belonging to the genus Redudasys (incertae sedis): this is the first finding of specimens of Redudasys outside of original type locality. These preliminary observations suggest that the knowledge of the biodiversity of Gastrotricha in the Minas Gerais State, as well as in the whole Brazil, will certainly increase as further investigations are undertaken, and that freshwater Macrodasyida may be more common than previously thought.

Correlation of male genital filaments and female spermathecal ducts in New World sand flies of the Lutzomyia intermedia species complex (Diptera: Psychodidae, Phlebotominae).  


The lengths of the male genital filaments and female spermathecal ducts were measured in phlebotomine sand flies of the Lutzomyia intermedia species complex and the ratios between these characters calculated. Ratios for L. intermedia s. s. from Northeast vs Southeast Brazil (Espírito Santo and Minas Gerais), Espírito Santo/Minas Gerais vs Rio de Janeiro/São Paulo and L. intermedia vs L. neivai were significantly different at P < 0.1, 0.05 and 0.01 respectively when compared using ANOVA. The spermathecal ducts and genital filaments of L. intermedia were significantly longer than those of L. neivai (P < 0.01) and could be used to differentiate these species. The taxonomic and biological significance of these differences is discussed. PMID:12973526

[The Meninos do Rio Program: lifeworld, adolescence, and health risks].  


This study focuses on health risks among teenagers from two towns in the Sao Francisco River Valley (Ibiai and Morada Nova) and slums in Morro das Pedras, Belo Horizonte, Minas Gerais State, Brazil. The study discusses teaching and extracurricular activities by the Federal University in Minas Gerais in these localities, aimed at promoting health in adolescence. The authors use the Habermas communicative action theory as the main theoretical and methodological approach. The research adopted a qualitative and quantitative methodology, including dynamic observation, focus groups, interviews, and questionnaires answered by high school students. Sexuality, work, and violence were the main themes and were associated with numerous health risks. Work in the 10-to-14-year-old group was associated with nearly all types of health risks. The authors analyze the relations between context and adolescent behavior using the Habermasian concept of lifeworld colonization. PMID:15692636

Mise en place du complexe filonien aurifère de la région d'Ouro Preto (Quadrilatère ferrifère, Brésil) : contraintes minéralogiques et pétrographiques  

NASA Astrophysics Data System (ADS)

Petrological and mineralogical analysis of gold-bearing quartz veins of the Ouro Preto area (Minas Gerais, Brazil) demonstrates: i) that gold, always associated with bismuth, is located within open fractures of quartz vein arsenopyrite; ii) that mineral association related to the mineralizing event developed later with respect to the regional metamorphism. These results are consistent with the structural studies that suggest a gold-bearing veins emplacement posterior to the regional metamorphism.

Niobium (columbium) and tantalum resources of Brazil  

USGS Publications Warehouse

Most of the niobium resources of Brazil occur as pyrochlore in carbonatites within syenitic intrusives of Late Cretaceous to early Tertiary age in western Minas Gerais and southeastern Goils. Minor amounts of it are produced together with tantalum from columbite-tantalite concentrates from pegmatites and placers adjacent to them, in the Sao Joao del Rei district in south-central Minas Gerais. All the niobium and tantalum produced in Brazil is exported. The only pyrochlore mined is from the Barreiro carbonatite deposit near Araxa in Minas Gerais where concentrates and ferroniobium are produced. Exploration work for pyrochlore and other mineral resources are being undertaken on other carbonatites, particularly at Catalao I in southeast Goias and at Tapira and Serra Negra in western Minas Gerais. Annual production and export from the Barreiro deposit are about 8,000 metric tons of pyrochlore concentrate containing about 60 percent Nb205 and about 2,700 metric tons of ferroniobium with 63 percent Nb2O5. The annual production capacity of the Barreiro plant is 18,000 tons of concentrate and 4,000 tons of ferroniobium. Ore reserves of the Barreiro deposit in all categories are 380 million tons with percent Nb2O5. Annual production of tantalite-columbite from the Sao Joao del Rei district, most of which is exported to the United States, is about 290 tons, of which about 79 percent is tantalite and about percent is columbite. Reserves of tantalite-columbite in the Sao Joao del Rei district are about 43,000 tons of proved and 73,000 tons of probable ore.

Mitochondrial genetic variability of Didelphis albiventris (Didelphimorphia, Didelphidae) in Brazilian localities  

PubMed Central

Didelphis albiventris is a well-known and common marsupial. Due to its high adaptability, this very widespread generalist species occurs under various environmental conditions, this even including protected regions and disturbed urban areas. We studied a 653 bp fragment of cytochrome oxidase c (COI) from 93 biological samples from seven Brazilian localities, with linear distances ranging between 58 and about 1800 km to analyze the effects of geographic distances on variability and genetic differentiation. The haplotype network presented nine haplotypes and two genetic clusters compatible with the two most distant geographic areas of the states of Minas Gerais, in the southeast, and Rio Grande do Sul, in the extreme south. As each cluster was characterized by low nucleotide and high haplotype diversities, their populations were obviously composed of closely related haplotypes. Surprisingly, moderate to high FST differentiation values and a very weak phylogeographic signal characterizes interpopulation comparisons within Minas Gerais interdemes, these being correlated with the presence of privative haplotypes. On a large rgeographic scale, a comparison between demes from Minas Gerais and Rio Grande do Sul presented high FST values and a robust phylogeographic pattern. This unexpected scenario implies that mtDNA gene flow was insufficient to maintain population cohesion, reflected by the observed high differentiation.

Biggest oil spill tackled in gulf amid war, soft market  

SciTech Connect

Industry is scrambling to cope with history's biggest oil spill against the backdrop of a Persian Gulf war and a softening oil market. U.S. and Saudi Arabian officials accused Iraq of unleashing an oil spill of about 11 million bbl into the Persian Gulf off Kuwait last week by releasing crude from the giant Sea Island tanker loading terminal at Mina al Ahmadi. Smart bombs delivered by U.S. aircraft hit two onshore tank farm manifold stations, cutting off the terminal's source of oil flow Jan. 26. A small volume of oil was still leaking from 13 mile feeder pipelines to the terminal at presstime. Press reports quoted U.S. military and Saudi officials as estimating the slick at 35 miles long and 10 miles wide but breaking up in some areas late last week. Meantime, Iraq reportedly opened the valves at its Mina al Bakr marine terminal at Fao to spill crude into the northern gulf. BBC reported significant volumes of crude in the water off Fao 24 hr after the terminal valves were opened. Mina al Bakr is a considerably smaller terminal than Sea Island, suggesting that the resulting flow of oil would be smaller than that at Sea Island.

A new instrument for high-resolution in situ assessment of Young's modulus in shallow cohesive sediments  

NASA Astrophysics Data System (ADS)

This paper describes a new, miniature, instrumented flat dilatometer (mIDMT) designed to assess variations in nearly continuous compressive stress-strain behaviour with depth in shallow cohesive sediments. The instrument was tested both in situ in the Bay of Fundy, Nova Scotia, Canada, and in cored samples from Willapa Bay, Washington, USA. Comparisons between probe and laboratory uniaxial assessments for other elastic materials—gelatine and foam rubber specifically—show strong agreement over the range of strains induced in the experiments. Observed values of Young's modulus ( E) for the gelatine and ethylene-vinyl acetate foam ranged from 6-343 kPa. Sediment stress-strain curves were distinctly linear for the overconsolidated fine-grained sediments of the Minas Basin, and values of E were found to increase with depth from near zero to 500-1,300 kPa at 20 cm depth. At the Willapa site, the sandy tidal flat sediments also behave elastically but E tended to increase more strongly with depth than for sediments from the Minas Basin. Young's modulus was inversely correlated to porosity at all sites tested, and linearly related to shear strength in the Minas Basin. The newly designed instrument has much finer resolution than for other, similar methods of determining E in situ, and it provides data at a resolution sufficient to assess small-scale processes such as gas bubble growth and infaunal locomotion, for which elastic constants are needed for modelling and prediction.

Potential effects of accumulating environmental policies on Dutch dairy farms.  


Consequences for farm management, environment, and economics of environmental policies for Dutch dairy farms were examined through modeling with two policies applied successively to typical dairy farms. Both policies aim to decrease nutrient losses in the soil. The first policy, the Mineral Accounting System (MINAS), is a farm gate balance approach that was introduced in 1998. Acceptable surpluses and levies are gradually tightened in this system until final standards are used in 2003. The second policy was developed to comply with the European Union Nitrate Directive and is called the Manure Transfer Agreement System (MTAS). This system links production and use of animal manure. Farms that produce more manure than the amount that can be applied on their own land according to standards are obliged to have a contract with a farmer who is willing to apply the surplus of manure on his farm. This system will be first applied in 2002 and final standards will be used in 2003. Results of the MINAS policy show fine-tuning of protein feeding especially by replacing grass in summer rations by maize silage and low protein concentrate. Another general result of MINAS is decreased use of N-fertilizer on grassland. As a consequence, division of the area between maize silage and grassland is adjusted. Income drop ranges from 1400 euros to 4800 (5 to 18%). Mineral Accounting System N surpluses drop by 45 to 113 kg/ha (23 to 37%). Adding MTAS is an incentive for more grassland as grassland has a higher manure application standard. Particularly for intensive farms, MTAS leads to high extra costs (2600 euros). However, expected environmental improvement is negligible. Therefore, from an environmental point of view there is no logic in adding the MTAS. PMID:12703639

Leaf water repellency of species in Guatemala and Colorado (USA) and its significance to forest hydrology studies  

NASA Astrophysics Data System (ADS)

Fog persistency and high precipitation totals contribute to the unique ecohydrology of tropical montane cloud forests. The persistence of water droplets on leaf surfaces in cloud forests inhibits photosynthetic carbon exchange because carbon dioxide diffuses slower in water than air. Adaptations that reduce water retention on leaf surfaces may increase photosynthetic capacity of cloud forests. The objective of the present study was to determine if 12 cloud forest species from the Sierra de las Minas, Guatemala have a higher degree of leaf water repellency than 12 species from tropical dry forests in Chiquimula, Guatemala and 12 species from foothills grassland vegetation in Colorado (USA). Leaf water repellency was measured as the contact angle between the leaf surface and the line tangent to the water droplet passing through the point of contact between the droplet and the leaf surface. Analysis of variance indicated that leaf water repellency was significantly different between the three study areas; however, the leaf water repellency of 12 species in the Sierra de las Minas was lower than 12 species in Chiquimula and lower than the leaf water repellency of 12 species in Colorado. Leaf water repellency of abaxial surfaces of all species in the cloud forest (Sierra de las Minas) was greater leaf water repellency of adaxial surfaces. The low values of leaf water repellency in cloud forest species may be influenced by presence of epiphylls or the loss of epicuticular wax on the leaf surfaces because of high precipitation totals and longer leaf life-span. High leaf water repellency in dry climates may be an adaptation to increase hydrological inputs underneath the canopy.

Geotourism in the "Estrada Real", Brazil  

NASA Astrophysics Data System (ADS)

Many natural landscapes are preserved throughout the World due to their cultural and historical values as well as for their environmental importance. The Way of Saint James of Compostela (Camino de Santiago de Compostela), located in Europe, is a well known example of this. It was the inspiration source for the development of a tourist route in the Brazilian States of Minas Gerais, Sao Paulo and Rio de Janeiro, although it has no pilgrimage connotation. The Estrada Real (literally translated as the Royal Route) is made of a series of roads or routes that were formerly used by the Portuguese colonizers to control the flow of gold, silver, diamonds and other precious stones and minerals. The tourist activities, particularly in the State of Minas Gerais, are experiencing an accelerated growth, benefiting the local and traditional communities economically. The existence of various geomorphological and geological sites in the Estrada Real has also favored the increase of the ecotourism and the Brazilian incipient geotourism. However, the uncontrolled touristic activities can damage the natural environment and some historical heritage sites. This research basically consisted in a preliminary identification of important geomorphosites such as caves and mountains that need to be protected for a rational and sustainable use. Out of the 4,632 known Brazilian caves, approximately 1,655 caves developed in limestone, dolomite, quartzite and granite are located in the State of Minas Gerais. For this reason, the authors strongly recommend that studies on the importance of such geomorphosites should take place in the municipalities of the Estrada Real in order to guide the regional development of tourism and sustainable development. Keywords: ecotourism, Estrada Real, sustainability.

Fumarole/plume and diffuse CO2 emission from Sierra Negra caldera, Galapagos archipelago  

NASA Astrophysics Data System (ADS)

Measurements of visible and diffuse gas emission were conducted in 2006 at the summit of Sierra Negra volcano, Galapagos, with the aim to better characterize degassing after the 2005 eruption. A total SO2 emission of 11 ± 2 t day-1 was derived from miniature differential optical absorption spectrometer (mini-DOAS) ground-based measurements of the plume emanating from the Mini Azufral fumarolic area, the most important site of visible degassing at Sierra Negra volcano. Using a portable multigas system, the H2S/SO2, CO2/SO2, and H2O/SO2 molar ratios in the Mina Azufral plume emissions were found to be 0.41, 52.2, and 867.9, respectively. The corresponding H2O, CO2, and H2S emission rates were 562, 394, and 3 t day-1, respectively. The total output of d
