    The tailing soils were from 10 mining areas in Hunan Province. To predict the potential impact of tailings on nearby environments, the characteristics such as the pH value, loss on ignition, cation exchange capacity, and the concentration and speciation of heavy metals in the tailings were investigated. Based on these characteristics, the pollution index and danger index were calculated so as to evaluate the priorities of remediation. The results show that the concentrations of Pb, Cd, Cu and Zn exceed the tolerable levels of the phytotoxicity in the most tailings. The large proportion of heavy metals exists in the form of residual fraction in most tailings, followed by sulfides/organic and Fe/Mn oxide fractions, and a little in the exchangeable and carbonate fraction. The calculated pollution indices for the tailing samples range from 1.41 to 83.42, which indicates that all the tailings contain heavy metals at a level that causes toxicity to the ecosystem. The danger indices for the tailing samples range from 0.06 to 387.00. The highest value of the danger indices is that of Yongzhou sample, reaching 387.00; the lowest one is that of Xikuangshan sample, only 0.06. Considering the results of pollution index and danger index in combination, the priority of remediation is determined to be Yongzhou, Baoshan, Xiangtan and Lengshuijiang.

    This study investigated the effect of sea surface temperature anomaly (SSTA) on flood-season precipitation in Hunan Province (the main grain-producing area in China) and change trend of the related flooding events. Based on the observation data of flood seasons in 44 stations of Hunan province from 1970-2013 and the sea surface temperature (SST) dataset from the Met Office Hadley Center, the empirical orthogonal function (EOF) analysis, power spectrum analysis and correlation analytical method have been conducted to identify the key time and marine regions which influence flood-season rainfall distribution. According to these analyses, two main spatial patterns of precipitation have been observed. The first and remarkable pattern is generally distributed uniformly throughout the region and is characterized by a 2-3-year and 20-23-year periods. The decadal variability has a negative correlation with the summer SSTA in the Indian Ocean near the equator, while the interannual variability is associated with the previous autumn and winter SSTA in the eastern Pacific. The second pattern illustrates dry-wet difference, indicating a north-to-south opposite, in a 3-year periods. The key area for influencing this mode is distributed in the Equator Pacific especially in the previous autumn and winter (known as ENSO). Furthermore, based on the EOF results of precipitation, we introduced the historical flooding event records of Hunan province and developed the spatial distribution maps and probability density curves for the direct economic losses in the years of anomaly and normal rainfall. The results reveal that the anomaly years suffer more serious losses and there is a corresponding relationship between north-to-south opposite precipitation mode and regional economic loss differences. With the function of illustrating the variation trend of hazards and the critical influence factor, these results are the data foundation for flood risk assessment. It can be used as a

Methods Using Spectrum (version:3.54) to estimate the number of new HIV infections, number of people living with HIV, need for ART in adults and children, need for PMTCT and cotrimoxazole in Beijing and Hunan Province. Data used in the model including high-risk populations monitoring data and demographic information, was collected from Beijing Center for Disease Control and Prevention, Hunan Center for Disease Control and Prevention and extracted from statistical yearbooks and published literatures. Results Few new HIV/AIDS were reported in Beijing prior to 1994, however, the number of HIV infections was increasing rapidly from 1995 to 2008, and decreased after that, increased rapidly again after 2012. The number of patients who need antiretroviral treatment was increasing among the group aged between 15-49 years with young patients aged 15-24 years peaked in 2010 and decreased rapidly after that. Few HIV-infected patients were reported before 1997 in Hunan Province, and the number of new infections was increasing rapidly since 1998. The number of patients who need antiretroviral treatment was increasing among the group aged between 15-49 years since 2000 with young patients aged 15-24 years in need of antiretroviral therapy increasing continuously. Conclusions After HIV infection was ifrst founded in Beijing and Hunan Province, there was a slow growth and then a rapid growth of HIV epidemic. According to prediction of Spectrum, the demand for antiretroviral therapy in Beijing would begin to decline since 2011, meanwhile, the HIV epidemic in Hunan Province would enter a rapid growth period with the demand for antiviral therapy continuing to increase. In this study, Spectrum was applied to estimate the HIV epidemic situation and need for treatment in the next ifve years in Beijing and Hunan Province. It provides the basis for health

The analyses of zircons from biotite monozonite granites for Weishan, Baimashan and Guandimiao plutons show the single and tight clusters on the concordia, and yield the weighted mean 206Pb/238U ages of 244±4, 243±3 and 239±3 Ma, respectively, representing the crystallized ages of these Indosinian granites. These data suggest that the Indosinian granitic plutons as previously thought formed at a narrow age span. In combination with other data, it is inferred that the Indosinian granites within the South China Block probably distributed in Hunan, Jiangxi, Guangxi and Guangdong provinces as planar shape, and were the derivation of the crustal materials in the intracontinental thickening setting. These precisely geochronological data provide important constraints for better understanding the spatiotemporal pattern of the Indosinian peraluminous granites and early Mesozoic tectonic evolution of the South China Block.

    China's coal-dominated energy pattern has resulted in large amount of SO2 emissions. Estimate of the sulfur-related health damage cost is necessary to help perform systematic cost-benefit analysis and set national energy and emissions control priorities. Current researches were confined to gaseous SO2 in urban areas; however, secondary sulfate (SO42-) particles can exert serious impact in a wider region. Based on the concept of "intake fraction", CALPUFF long-range dispersion model and 180 sample emission sources, multiple regression equation was obtained with good correlation(r=0.85), which illustrates that populations were key parameters to determine intake fraction but source characteristics were insignificant. Based on the formula and the population distribution data, county-level intake fractions were mapped for Hunan Province(range: 1.1×10-6-3.2×10-6) of China. A combination of county-level SO2 emissions with the intake fractions yields a total 1.98 tons of sulfate(SO42-) inhalation, and resulting total health damage cost to be 0.76(willingness to pay approach) or 0.16(human capital approach) billion USD in 1997, about 2.1% or 0.45% of GDP in Hunan in 1997. Average health damage cost per ton of SO2 emission is 930(willingness to pay approach) or 200 USD(human capital approach). The results demonstrated that more stringent regulation should be forced.

    Full Text Available Background: With the development of economy and urbanization, methods of child-feeding have significantly changed in China over the past three decades. However, little is known about breastfeeding in China since 2009. This study aims to update information on the prevalence of breastfeeding in China. Methods: Data were obtained from the first Health Service Household Interview Survey of Hunan Province, China. Of 24,282 respondents, 1659 were aged five years or younger. We ran multivariable logistic regression to examine the impact of urban/rural setting, gender, age and household income per capita on the use of breastfeeding. Results: A total of 79.4% of children aged 5 years or younger had been breastfed at some point and 44.9% been breastfed exclusively in the first 6 months of life. After controlling for setting urban/rural setting, gender and child age, children from households with average family income were more likely to be breastfed than those from households with the lowest family income (adjusted odds ratio: 2.28. Children from households with higher and the highest family income were less likely to be exclusively breastfed in the first 6 months of life compared to those from households with the lowest family income (adjusted odds ratio: 0.51 and 0.68, respectively. Conclusions: It is encouraging that the prevalence of exclusive breastfeeding for infants in the first 6 months of life in Hunan Province, China is approaching the goal of 50% proposed by the World Health Organization (WHO. Nevertheless, more efforts are needed to further promote exclusive breastfeeding in the first 6 months after birth.

The lava cave occurs in a compound pāhoehoe flow of Karla Formation, characterized by the presence of lobes, toes and small scale features like squeeze-ups. Field observations and measurements reveal that the dimensions of the cave are small, with low roof and a maximum width of 108 cm. The cave morphology along the 20 m passage varies from circular to semi-circular, with a twilight zone to the north. The gentle micro-topography at Ghoradeshwar controlled the advancement of pāhoehoe lobes and toes within the sheet lobe. The pre-flow gradients towards the north led to the progression of flow from the east, where the cave opening is presently seen. Dimensions and related morphology of the lava cave suggest that it can be best described as a small sub-crustal cave formed by draining of an inflated of pāhoehoe lava lobe. At Ghoradeshwar, besides the natural lava cave, Buddhist caves carved in pāhoehoe lava flows are also observed, indicating that early man took advantage of the existing openings in pāhoehoe flows and sculpted the caves to suit their requirements.

    Since 2004, three excavations have been carried out at a late Pleistocene human fossil site of Huan-glong Cave in Yunxi County, Hubei Province of China, which unearthed seven human teeth, dozens of stone tools, mammal fossils and other evidence indicating human activities. During the third excava-tion in 2006, in the same layer as the human teeth, we found some patches of black materials embed-ded in the deposit. We doubted that this black deposit layer is the remains of burning or even human use of fire at the cave. To further explore the possibility of human fire use at the Huanglong Cave, we examined samples directly taken from the black deposit layer and compared them with samples taken from several places in the cave using three methods: micromorphology, element content determination and deposit temperature analysis. Our results indicate that the contents of carbon element in the black deposit reach 64.59%-73.29%. In contrast, contents of carbon element of the comparative samples from other parts in the cave are only 5.82%-9.49%. The micromorphology analysis of the black de-posit samples reveals a plant structure like axial parenchyma, fibrocyte, uniseriate ray and vessel.High-temperature magnetic susceptibility measurements suggest that the stratum possibly underwent a high temperature in the nature. Based on these lab analyses, we are sure that the black layer in the Huanglong Cave is the remains of fire and combustion did occur in the cave 100000 years ago. Taking other evidence of human activities found in the Huanglong Cave into consideration, we believe that the evidence of fire from the Huanglong Cave was caused by the human activities of controlled use of fire.

    We studied Cd, Cr, As, Ni, Mn, Pb, and Hg in three agricultural areas of Hunan province and determined the potential non-carcinogenic and carcinogenic risks for residents. Soil and brown rice samples from Shimen, Fenghuang, and Xiangtan counties were analyzed by atomic absorption spectroscopy. Soil levels of Cd and Hg were greatest, followed by As and Ni. The mean concentrations of heavy metals in brown rice were Cd 0.325, Cr 0.109, As 0.344, Ni 0.610, Mn 9.03, Pb 0.023, and Hg 0.071 mg/kg, respectively. Cd and Hg had greater transfer ability from soil to rice than the other elements. Daily intake of heavy metals through brown rice consumption were estimated to be Cd 2.30, Cr 0.775, As 2.45, Ni 4.32, Pb 0.162, Mn 64.6 and Hg 0.503 µg/(kg·day), respectively. Cd, Hg and As Hazard Quotient values were greater than 1 and Cd, Cr, As and Ni Cancer Risk values were all greater than 10(-4). The total non-carcinogenic risk factor was 14.6 and the total carcinogenic risk factor was 0.0423. Long-term exposure to heavy metals through brown rice consumption poses both potential non-carcinogenic and carcinogenic health risks to the local residents.

    The Yangjiatan tungsten district at latitude 27??28??? N. and longitude 111??54???E. is located about 140 km southwest of the city of Changsha and 35 km northeast of the town of Shaoyang, southeast Hunan Province, People's Republic of China. The deposits, consisting largely of scheelite in veins (Wang, 1975), are contained in highly folded and faulted sedimentary rocks of Paleozoic, Mesozoic, and Cenozoic age intruded by granitic plutons that are circular in plan view. The major faults and folds trend in a northeasterly direction; whereas, the plutons are clustered in a more easterly trending band across the Landsat image. Landsat image E-2338-02202, acquired December 26, 1975, is number 470 in the "Landsat Image Atlas of the People's Republic of China" printed by the Publishing House of Geology in 1979. A computer-compatible tape of the image was analyzed and used as a demonstration project under a United Nations technical assistance program. Supervised classification of soils, rocks, and vegetation; band ratioing to detect limonite alteration; and edge enhancement were all conducted to demonstrate the flexibility and capability of interactive computer systems. Field evaluation of the results of this work will be conducted by colleagues of the Remote Sensing Center for Geology, Ministry of Geology, in China. ?? 1983.

    Using NCEP 1°× 1° reanalysis data within 6 h, conventional observational data, data from regional automatic rainfall stations, satellite cloud pictures and Doppler radar data, we compared the physical conditions, dynamic and thermodynamic characteristics of two rainstorms in the southwest of Hunan Province on May 12 and June 15 in 2011. The results showed that the first process was triggered by strong cold air under unstable potential, while the second process was caused by shear line appearing from the east; during the first process, cold air divided into many parts and moved towards south, rainfall was uniform and lasted for a long time, while rainfall was relatively concentrated and strong, and lasted for a short time during the second process; the peak of K index appeared only during the second process; no sign of heavy rainfall was found from satellite cloud pictures and radar echo pictures during the first process, while obvious cloud cluster and echo ribbons could be found from satellite cloud pictures and radar echo pictures during the second process, which were the sign of heavy rainfall; slow movement of echo or little movement resulted in the second rainstorm, and constant echo intensity was the main reason for the occurrence of the second rainstorm. In addition, there was low-level southwest jet during the two processes, which provided favorable conditions for the transportation of water vapor and energy during the two processes. However, there was a great difference between the two rainstorms in the intensity and thickness of low-level jet, that is, the intensity and thickness of low-level jet during the first process were obviously weaker than these during the second process.

    In 2015, only 49% of notified multi-drug resistant tuberculosis (MDR-TB) patients in China were estimated to have initiated treatment, compared with 90% of those worldwide. A case-control study was conducted to identify the reasons for non-enrollment in treatment among MDR-TB patients in Hunan province, China. All detected MDR-TB patients registered in designated MDR-TB hospitals in Hunan province from 2011 to 2014 were included and followed until June 2015 to determine their treatment status. Approximately 33.8% (482/1425) of patients were not enrolled in standardized treatment. Factors associated with lower enrollment rate were: age greater than 60 years, living in rural area, unemployed or occupation unreported. Of those who were not enrolled in MDR-TB treatment, the primary reasons for non-enrollment included economic hardship (23.0%), out-migration for work (18.0%), concerns about work and studies (13.7%), and the belief that they were cured after undergoing drug-sensitive TB treatment (12.4%). Therefore, comprehensive strategies targeting priority populations, especially those enhancing treatment affordability and availability, need to be implemented to improve MDR-TB control.

    Based on the basic connotation of comprehensive agricultural production capacity,this article establishes the comprehensive agricultural production capacity indicator system on the basis of statistics. This indicator system consists of 5 parts ( input scale of factors,output scale of factors,output rate of factors,ability to resist disaster and ensure production,and modern operation level) and 14 specific indicators. Based on factor analysis method,we use this indicator system to conduct systematic empirical analysis of the level of comprehensive agricultural production capacity in 14 cities and prefectures of Hunan Province. The results show that although the overall level of comprehensive agricultural production capacity in Hunan Province tends to grow continuously and steadily,there are significant inter-regional differences in the level of comprehensive agricultural production capacity; in terms of the level of comprehensive agricultural production capacity,there is great room for improvement. Finally the following policy recommendations are put forward: strengthening balanced regional development and improving the overall level of comprehensive agricultural production capacity; strengthening the building of land carrying capacity; strengthening the building of agricultural ecological balance; strengthening the building of the scientific and technological support capacity.

    The contents, affecting factors, seasonal changes and availability of fixed ammonium in major types ofpaddy soils derived from different parent materials in Hunan Province, China, were studied using the Silva-Bremner method by laboratory and pot experiments. Results showed that the content of fixed ammoniumin the plough horizons ranged from 88.3 mg kg-1 to 388.1 mg kg-1, with 273.2 ± 77.7 mg kg-1 on average,accounting for 11.2% of total soil N on average. Content of fixed ammonium decreased in the order of newlylacustrine clayey paddy soil > alluvial sandy paddy soil > purple clayey paddy soil > newly alluvial sandypaddy soil > yellow clayey paddy soil > reddish-yellow clayey paddy soil > granitic sandy paddy soil. Therewere four distribution patterns of fixed ammonium in the profiles to 1-m depth, i.e., increase with the depth,decrease with increasing depth, no distinct change with the depth, and abrupt increase or decrease in somehorizon. Percentage of fixed ammonium in total N increased with the depth in most of the soils. Fixationof NH4+ by soil was higher at 30 ℃ than at 20 ℃ and 40 ℃, and continuous submergence benefited thefixation of NH4+ in newly alluvial sandy paddy soil, purple clayey paddy soil and alluvial sandy paddy soil,while alternating wetting and drying contributed to the fixation of NH4+ in yellow clayey paddy soil mostly.Fixed ammonium content in the test paddy soils was significantly correlated with < 0.01 mm clay content(P < 0.05), but not with < 0.001 mm clay content, total N, organic N and organic matter. Fixed ammoniumcontent varied with rice growth stages. Application of N fertilizer promoted fixation of NH4+ by soil, and Nuptake by rice plant promoted release of fixed ammonium from the soil. Recently fixed ammonium in paddysoil after N fertilizer application was nearly 100% available to rice plant, while native fixed ammonium wasonly partly available, varying with the soil type and rice type.

    For the past 20 years the modern human origins debate has received a significant amount of attention in paleoanthropological research. Primarily supported by the evidence of earlier dates of anatomically modern human fossils and genetic studies, the "Out of Africa" hypothesis is based on the belief that the ancestor of all modern humans, including modern Chinese, came from Africa. The opposite hypothesis "Mutiregional evolution" proposes that continuous evolution occurred on a regional scale, for which human paleontology offers strong support. However, due to the paucity of hominid fossils in China between 100 and 50 ka, support to the latter hypothesis is currently weak. This is a report here of five human fossil teeth, and associated stone tools and mammal fossils from a newly discovered cave site, Huanglong Cave, located in Yunxi County,Hubei Province, China. Preliminary studies indicate:(1) the morphological features of the human fossils resemble those of late Pleistocene human fossils from China; (2) the stone tools display patterns of both the southern and northern Paleolithic cultures of China; (3) the mammal fossils represent the "Ailuropoda-Stegodon" faunal unit which lived in southern China throughout the Pleistocene. ESR and U-series dating on animal teeth and a stalagmite derived from the same layer as the human teeth indicate two possible ages: 103±1.6 ka and 44±12.5 ka. In addition to other evidence presented here, it is believed that hominid occupation of the cave was likely around 100 ka. If this age is further substantiated, Huanglong Cave will be the first late Pleistocene hominid fossil site in China where anatomically modern humans lived about 100 ka. The human fossils and other related materials from Huanglong Cave will provide important information for research on the origin of modern Chinese.

    Existing data on the genotype distribution of human papillomavirus (HPV) are limited in Hunan province, central south China. To evaluate the prevalence of HPV infection and its genotype among women with invasive cervical cancer in Hunan, a total of 1,336 patients were included in this study between July 2012 and June 2013. Eighteen high-risk and eight low-risk genotypes of HPV were detected by Luminex xMAP technology. The results show that HPV prevalence in invasive cervical cancer in Hunan was 75.7%. A single HPV infection was found in 82.3% of the HPV-positive samples, and 91.8% of the cases had high-risk HPV infection. The most common HPV type was HPV 16 (50.6%), followed by HPV 58 (12.4%), HPV 52 (10.9%), HPV 18 (7.3%), HPV 33 (5.5%), HPV 59 (4.2%), HPV 39 (4.0%), HPV 61 (3.4%), HPV 31 (3.3%), and HPV 56 (3.2%). A single infection with HPV 16 was detected in 42.5% of the samples, which was significantly more frequent than any other HPV type in this population. Dual-infection with HPV 16 and HPV 52 were relatively common. The available vaccines for HPV 16 and 18 are therefore expected to have a substantial impact on reducing the burden of cervical cancer in China, even though HPV 18 showed a lower frequency. In addition to HPV 16 and 18, other HPV types including 58, 52, and 33, should be targeted in the next generation HPV vaccines.

    Full Text Available H9N2 avian influenza viruses (AIVs are highly prevalent and of low pathogenicity in domestic poultry. These viruses show a high genetic compatibility with other subtypes of AIVs and have been involved in the genesis of H5N1, H7N9 and H10N8 viruses causing severe infection in humans. The first case of human infection with H9N2 viruses in Hunan province of China have been confirmed in November 2013 and identified that H9N2 viruses from live poultry markets (LPMs near the patient's house could be the source of infection. However, the prevalence, distribution and genetic characteristics of H9N2 viruses in LPMs all over the province are not clear. We collected and tested 3943 environmental samples from 380 LPMs covering all 122 counties/districts of Hunan province from February to April, 2014. A total of 618 (15.7% samples were H9 subtype positive and 200 (52.6% markets in 98 (80.3% counties/districts were contaminated with H9 subtype AIVs. We sequenced the entire coding sequences of the genomes of eleven H9N2 isolates from environmental samples. Phylogenetic analysis showed that the gene sequences of the H9N2 AIVs exhibited high homology (94.3%-100%. All eleven viruses were in a same branch in the phylogenetic trees and belonged to a same genotype. No gene reassortment had been found. Molecular analysis demonstrated that all the viruses had typical molecular characteristics of contemporary avian H9N2 influenza viruses. Continued surveillance of AIVs in LPMs is warranted for identification of further viral evolution and novel reassortants with pandemic potential.

    Systematic geochemical studies of the Proterozoic Lengjiaxi Group in northeastern Hunan Province suggest that the Lengjiaxi Group is a Au-As-Sb-W association-type Au-bearing turbidite formation.The contents of Au,As,Sb,W,Cr,Mn,Pb and Zn in the turbidite formation are more than two times as high as the average contents of trace elements in the upper continental crust.The low abundance of Ag and the close correlation between Au and As are two important characteristic features.In the Au-bearing turbidite formation the enrichment of gold is due to the extensive occurrence of Au-bearing pyrites.Higher contents of Au,W,Sb and Ag in the greywacke indicate that they also exist in the form of heavy minerals.Au,Ag,As,Sb,W and REE in the Au-bearing turbidite formation have a close genetic relation with the chemistry of the gold deposits.

  3. Ecological evolution across the Permian/Triassic boundary at the Kangjiaping Section in Cili County, Hunan Province, China

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    The stratigraphic sequence of calcimicrobialite facies at the Permian-Triassic (P/Tr) boundary has well recorded the biotic and environmental transition across the end-Permian catastrophic events. The biostratigraphy, microfacies, carbon isotopes, and fossil records across the P/Tr boundary have been studied at the Kangjiaping Section in Cili County, Hunan Province. Three biostratigraphic zones, Palaeofusulina-Colaniella Zone, Hindeodus parvus Zone, and Isarcicella staeschei Zone, are identified. The excursion of δ13Ccarb exhibits a sharp negative shift in the calcimicrobialite at the P/Tr boundary, which is roughly accordant with the abrupt bioclastic decline. In addition, five types of microfacies are recognized, including algal-foraminifer bioclastic limestone, algal-laminated calcimicrobial limestone, oolitic grainstone, vermiculate limestone, and intraclastic wackstone. The results indicate that the changeover of ecosystem from metazoan reef to calcimicrobialite in Cili is a classic case of marine ecological evolution during the Paleozoic-Mesozoic transition.

    In this study, the trends and periodicity in climate extremes are examined in Hunan Province over the period 1960-2013 on the basis of 27 extreme climate indices calculated from daily temperature and precipitation records at 89 meteorological stations. The results show that in the whole province, temperature extremes exhibit a warming trend with more than 50% stations being statistically significant for 7 out of 16 temperature indices, and the nighttime temperature increases faster than the daytime temperature at the annual scale. The changes in most extreme temperature indices show strongly coherent spatial patterns. Moreover, the change rates of almost all temperature indices in north Hunan are greater than those of other regions. However, the statistically significant changes in indices of extreme precipitation are observed at fewer stations than in extreme temperature indices, forming less spatially coherent patterns. Positive trends in indices of extreme precipitation show that the amount and intensity of extreme precipitation events are generally increasing in both annual and seasonal scales, whereas the significant downward trend in consecutive wet days indicates that the precipitation becomes more even over the study period. Analysis of changes in probability distributions of extreme indices for 1960-1986 and 1987-2013 also demonstrates a remarkable shift toward warmer condition and increasing tendency in the amount and intensity of extreme precipitation during the past decades. The variations in extreme climate indices exhibit inconstant frequencies in the wavelet power spectrum. Among the 16 temperature indices, 2 of them show significant 1-year periodic oscillation and 7 of them exhibit significant 4-year cycle during some certain periods. However, significant periodic oscillations can be found in all of the precipitation indices. Wet-day precipitation and three absolute precipitation indices show significant 1-year cycle and other seven provide

    Located in Central South China, Hunan province is rich in mineral resources. To study the influence of mining on Cd pollution to local agricultural eco-system, the paddy soils and rice grain of Y county in northern Hunan province were intensively monitored. The results were as follows: (1) Total Cd (T-Cd) content in the soils of the county ranges from 0.13 to 6.02 mg kg(-1), with a mean of 0.64 mg kg(-1), of which 57.5% exceed the allowable limit specified by the China Soil Environmental Quality Standards. T-Cd in the soils varies largely, with the coefficient of variation reaching 146.4%. The spatial distribution of T-Cd in the soils quite matches with that of mining and industries. The content of HCl-extractable Cd (HCl-Cd) in the soils ranges from 0.02 to 2.17 mg kg(-1), with a mean of 0.24 mg kg(-1). A significant positive correlation exists between T-Cd and HCl-Cd in the soils (r = 0.770, ρ soils (r = 0.091, ρ > 0.05), which suggests that the amount of Cd accumulating in the rice is more affected by its availability in the soils, rather than the total content. (4) The dietary intake of Cd via rice consumption in Y county is estimated to be 179.9 μg day(-1) person(-1) on average, which is far beyond the allowable limit specified by FAO/WHO and the target hazard quotients of Cd much higher than 1, suggesting the high risk on human health from Cd exposure.

    To understand and master the dynamic variation of the pandemic influenza A (H1N1) 2009 in Hunan province from 2009 to 2011, and to know the genetic characteristics and drug resistance of the pandemic (H1N1) 2009 viruses. Throat swab specimens of influenza-like illness patients were collected from sentinel hospitals and tested for influenza by fluorescent PCR or virus isolation methods. Partial isolates were selected for sequencing. The sequences were used for phylogenetic analysis by MEGA 5. 05 software. From the 20th week of 2009 to the 52nd week of 2011, 17 773 specimens were tested. 3 831 specimens were influenza-positive with a positive rate of 21. 6%, of which 1 794 were positive specimens of pandemic (H1N1) 2009, accounting for 46. 8%00 of the influenza-positives. There were 2 epidemic peaks of pandemic (H1N1) 2009, which were in the 41st-53rd week of 2009 and the 1st-12nd week of 2011, respectively. The HA genes of 23 strains that were selected for sequencing had close relationship; the distribution of strains in the phylogenetic tree was basically in chronological order. The complete genome sequence analysis showed that all of 8 gene segments of 7 strains were homologous to the vaccine strain, and there was no gene reassortment. The HA amino acid sites of the 23 strains were highly similar to the vaccine strain (98. 2% - 100. 0% in homology), but all 23 strains had P83S, S203T and 1321V mutations. The 222 site mutation that may lead to enhanced virulence was found in the A/Hunan/YQ30/2009 strain. The mutation was D222E. There was no oseltamivir resistance mutation found in all strains. The pandemic (H1N1) 2009 in Hunan province from 2009 to 2011 had a bimodal distribution. There was no large-scale variation of virus genes. The clinical use of oseltamivir was still effective.

The prevalence rates of BDs with 95% confidence interval (CI and crude odds ratio (ORs were calculated to examine the associations of infant gender, maternal age, and region (urban vs rural with BDs.From 2005 to 2014, there were a total of 925413 perinatal infants of which 17753 had BDs, with the average prevalence of 191.84 per 10000 PIs (perinatal infants, showing a significant uptrend. The risks of BDs are higher in urban areas versus rural areas (OR = 1.20, in male infants versus female infants (OR = 1.19, and in mothers above age 35 versus those below age 35 (OR = 1.24. The main five types of BDs are Congenital heart defects (CHD, Other malformation of external ear (OMEE, Polydactyly, Congenital malformation of kidney (CMK, and Congenital talipes equinovarus (CTE. From 2005 to 2014, the prevalence rates (per 10000 PIs of CHD and CMK increased significantly from 22.56 to 74 (OR = 3.29, 95%CI: 2.65-4.11 and from 7.61 to 14.62 (OR = 1.92, 95%CI:1.30-2.84, respectively; the prevalence rates of congenital hydrocephalus and neural tube defects (NTDs decreased significantly from 11.8 to 5.29 (OR = 0.45, 95%CI: 0.31-0.65 and from 7.87 to 1.74 (OR = 0.22, 95%CI: 0.13-0.38, respectively.The prevalence rates of specific BDs in perinatal infants in Hunan have changed in the last decade. Urban pregnant women, male perinatal infants, and mothers above age 35 present different prevalence rates of BDs. Wider use of new diagnosis technology, improving the ability of monitoring, strengthening the publicity and education are important to reduce the prevalence of BDs.

    The multi-functionality of paddy farming has become a hot issue recently. Paddy farming provides numerous ecosystem services that are crucial to human wel-being. However, evaluation of the contribution of paddy farming to human wel-being usualy focus on its economic value, while its non-market services are usualy ignored. Only evaluating the market proifts or market relative beneifts cannot relfect comprehensively the contribution of paddy farming to people’s wel-being. This wil affect people’s choices for or against paddy farming activities and people’s opt for invest or not invest in it. A compre-hensive evaluation of paddy farming can provide an important reference for the government and society to conserve the multi-functionality of paddy farming and achieve sustainable development. To this end, this paper reports a case evaluation of paddy farming in Hunan, the largest rice producing as wel as rice yield province in China, and uses emergy theory to make a comprehensive evaluation for paddy farming. The emergy evaluation results of the paddy ecosystem in Hunan are as folows: in 2010, the input emergy of the paddy ecosystem in Hunan is 2.51E+22 sej and the output emergy is 6.31E+22 sej. For the input emergy, the part from natural resources is 1.96E+21 sej and the part from human society is 2.32E+22 sej; for the output emergy, the part from products is 2.22E+22 sej, the part from impositive externality is 4.16E+22 sej and the part from negative externality is –7.41E+20 sej. Taking the non-market outputs into consideration, the gains from the human economic society’s 1 $ input in paddy farming, emergy sustainability index (ESI) and emergy proift rate are re-spectively 2.73 $, 3.53 and 151.31%. If the evaluation leave out the non-market output, the three indexes are only 0.96 $, 1.24 and 30.67%. The research results show that non-market services of paddy farming contribute signiifcantly to human wel-being. Therefore, in order to protect the multi

    Long-term variation of estimated global solar radiation (E g↓) and its relationship with total cloud cover (TCC), low cloud cover (LCC), water vapor content (WVC) and aerosol optical depth (AOD) were investigated based on the observations at 21 meteorological stations in Hunan province, China. Long-term variations of all variables were calculated for each station; the Mann-Kendall trend test was used to detect the significant level of temporal development trend for each variable; the Pearson correlation analysis was used to measure their linear relationships. Annual E g↓ generally decreased at the rate of -2.11 × 10-3 MJ m-2 decade-1 in Hunan province during 1980-2013. Seasonal mean E g↓ decreased at the rate of -11.99 × 10-3, -4.71 × 10-3 and -4.51 × 10-3 MJ m-2 decade-1 in summer, autumn and winter, respectively, while the increasing trend was observed in spring (15.74 × 10-3 MJ m-2 decade-1). The annual variation of E g↓ in Hunan province was dominantly determined by the variations of AOD (0.33 × 10-3 decade-1) and LCC (0.24 % p decade-1). But the spatial variation of E g↓ in Hunan province was complex. All 21 stations were divided into four groups according to the long-term trends of E g↓, TCC, LCC, AOD and WVC. An increasing E g↓ was observed at stations in group 1, which was determined by the variability of TCC. The variability of AOD and TCC might contribute to the increasing E g↓ in group 2. There were decreasing trends of E g↓ for the stations in group 3 and group 4, which were largely determined by the increases of AOD and LCC.

    A region-wide sampling survey was conducted in 1995 in order to evaluate the current epidemiological status of schistosomiasis japonica in Hunan Province, China. A total of 45,590 humans and 3,726 domestic animals, from 52 villages, were examined parasitologically and/or serologically for current Schistosoma japonicum infections. In uncontrolled endemic areas (43 villages) the overall human prevalence of S. japonicum was 7.81% across the different geographical subtypes. The geometric mean intensity of infection was 17.71 eggs per gram (epg) among infected individuals and only 1.25 epg in the general population. The bovine prevalence, as determined by the hatching test, was 9.63% in the uncontrolled endemic villages. Only one sero-positive (by indirect hemagglutination assay) child was found among 1,072 children tested aged 10-14 years in the 9 endemic villages under effective control. No infection was confirmed by the Kato-Katz thick smear stool examination. When the results of this survey were compared to those seen at baseline (1989) an overall reduction of 45.65% was seen in the human prevalence but no significant change was apparent in the lake-beach ecotype. Additionally, there was more than a 60% reduction in the prevalence among bovines over the same sampling period. The results demonstrate that the World Bank Loan Schistosomiasis Program was successful in achieving its most basic objectives for this province - to reduce human and bovine infections by 40%.

    Although there are abundant natural resources in nature reserves, poverty is a common feature of the social economy in the communities surrounding nature reserves. Income from forestry is still the main source for residents living around nature reserves.The structure of inputs and outputs, i.e. productivity, in the forestry sector in nature reserves is quite different from one reserve to another. Productivity can be measured by Data Envelopment Analysis (DEA) methods owing to the characteristics of DEA. The promotion of productivity in nature reserve is an effective way to improve the living condition in areas neighboring nature reserves.Thus, one typical national nature reserve in Hunan is selected in this study with the intent to measure productivity in the area and then to analyze the factors affecting its productivity.

    In order to explore input pathways and pollution characteristics of Cd contamination in paddy soil in Youxian, Hunan Province, Cd contents in paddy soils, sediments of irrigation canals, typical mineral and industrial products such as coal, gangue and cement were analyzed. It was suggested that the average contents of Cd both in surface paddy soil and the corresponding natural soil were higher than the soil quality standard 0.3 mg x kg(-1). Cd contents in gangue and cement were similar as those in the corresponding natural soils. The atmosphere deposition of Cd was the highest in factory area. The profiles of Cd in 0-100 cm paddy soil and 0-40 cm in natural soils varied significantly from the upper to the lower layer. Cd contents in 0-40 cm layer in paddy soil were much higher than those in corresponding natural soils in mineral and mineral-factory areas. The potentiality for downward movement of Cd in soils in mineral area was the highest among the three studied areas. It suggested Cd contents in surface paddy soil were higher in upwind areas than those in downwind areas in mineral-factory and factory areas. It could be concluded that the main input pathways of Cd in mineral and mineral-factory. areas were from irrigation water, while contribution of atmosphere deposition in mineral-factory and factory areas was also very significant.

    The stratigraphic sequence of calcimicrobialite facies at the Permian-Triassic (P/Tr) boundary has well recorded the biotic and environmental transition across the end-Permian catastrophic events.The bio-stratigraphy,microfacies,carbon isotopes,and fossil records across the P/Tr boundary have been studied at the Kangjiaping Section in Cili County,Hunan Province.Three biostratigraphic zones,Pa-laeofusulina-Colaniella Zone,Hindeodus parvus Zone,and Isarcicella staeschei Zone,are identified.The excursion of δC exhibits a sharp negative shift in the calcimicrobialite at the P/Tr boundary,which is roughly accordant with the abrupt biociastic decline.In addition,five types of microfacies are recognized,including aigal-foraminifer bioclastic limestone,algal-laminated calcimicrobial limestone,oolitic grainstone,vermiculate limestone,and intraclastic wackstone.The results indicate that the changeover of ecosystem from metazoan reef to calcimicrobialite in Cili is a classic case of marine ecological evolution during the Paleozoic-Mesozoic transition.

    Contents of lead in several crops as well as its uptake and distribution by paddy in typical lead-zinc deposit area of western Hunan province were studied based on field systematic sampling and laboratory analysis. The average concentration of lead in rice, maize and soy bean in the deposit was 2.4, 1.2 and 3.3 times higher than that in control area, respectively, suggesting that crops in the deposit were heavily contaminated by the element. Significant difference of the lead concentrations in crops was found among different crop species and different organs of the same crops. The average concentration of lead followed the trend: soy bean > rice > maize (among crop species), and root > haulm > seed (among organs). Paddy root exhibited strong binding and tolerant capacity to lead. Correlation analysis indicated that soil lead was main retention in paddy root, whereas the gaseous lead might be the main source for lead in the aerial part of crop. Heavy metals such as Hg, Cd as well as Pb co-enriched in crops, therefore the mechanism and health risk of the combined pollution of heavy metals in the deposit crops should be paid attention to.

    Objective: To investigate the characteristics of transmission correlativity regarding subtype B among elderly HIV-1 infected individuals in Yongding district, Zhangjiajie city, Hunan province and to explore a method on its traceability. Methods: A total of 43 newly diagnosed elderly HIV-1 Infected individuals in Yongding district were enrolled in this study. Pol area genes were amplified and sequenced by 'In house' method. Methods used to analyze the relationship related to HIV individuals transmission would include Bayesian phylogenetic tree and other epidemiological ones. Results: A total of 42 valid sequences were successfully obtained, with predominant strain as subtype B (80.95%, 34/42). All the 42 sequences were gathered into eight clusters. In each cluster, the genetic distance was significantly shorter than the average from the 34 subtype B strains (0.058 3). The HIV-1 infected individuals in one cluster had the same high-risk behaviors and the significantly patchy distributions were identified at the sites where the high-risk behaviors existed. Our results indicated that the local elderly HIV-infected individuals had high level of homology between geographical position and related behaviors. Conclusions: The patchy distribution between geographical position and behavior was associated among the elderly HIV-1 infected individuals. Guidance related to epidemic precise positioning and effective interventions was provided through the findings of this study.

    Phlebotomines are invertebrate hosts of Leishmania genus species which are etiological agents of leishmaniases in humans and other mammals. Sandflies are often collected in entomological studies of caves both in the inner area and the adjacent environments. Caves are ecotypes clearly different from the external environment. Several caves have been opened to public visitation before any studies were performed and the places do not have scientific monitoring of the fauna, flora, geological and geographical characteristics. These events can lead to the loss of geological and biological information. Considering these aspects, this study aimed to describe the sand fly fauna, including the ecological features, in a limestone cave at the Speleological Province of Bambuí (Minas Gerais State, Brazil). A total of 8,354 specimens of sandflies belonging to 29 species were analyzed: Lutzomyia cavernicola (20%), Nyssomyia intermedia (15%), Martinsmyia oliveirai (13%), Evandromyia spelunca (12%), Evandromyia sallesi (11%), Migonemyia migonei (9%), Nyssomyia whitmani (9%), Sciopemyia sordellii (4%) and Lutzomyia longipalpis (2%). The others species represent 5% of the total. This manuscript presents data found on richness, diversity, evenness and seasonality, comparing the sand fly fauna trapped in the cave and its surroundings.

    The shale at the bottom of the Lower Cambrian black series in South China is rich in nonferrous metals, noble metals, rare and dispersed elements and radioactive elements, known as "polyelement-rich bed". In order to date and trace the source of the platinum group elements, 6 samples were collected from the Zhongnan region of Guizhou Province, and the Ganzi- ping-Sancha region of Hunan Province. The contents and isotopes of Re and Os were measured. Re and Os are positively correlated with each other and the correlation coefficient between 187Os/188Os and 187Re/188Os is 0.99856. On the 187Os/188Os-187Re/188Os diagram, 6 sample points are well-distributed along the (542±11) Ma fitting isochron in high coincidence and with 0.84±0.12 as the initial 187Os/188Os value. The result displays that the age value of the major mineralization of Re, Os and other platinum group elements is (542±11) Ma, which is identical with the stratigraphical age of the wall rocks; the 'polyelement beds' in Hunan and Guizhou provinces bear high isochroneity; the differences of the forming times of different materials in the 'polyelement bed' of the same area do not surpass the error limit permissible for Re-Os date fitting; there exists no distinct time interval between the formation of the diagenetic veinlets and that of the 'polyelement bed', or the Re-Os isotope composition has not been distinctly changed by the former process; basaltic crust might be the major source of Re, Os, other platinum group and trace elements in the Lower Cambrian 'polyelement bed' of Hunan and Guizhou provinces.

Moreover, most Chinese citizens accept their health care services in first- and second-level PHs for economic and geographical reasons, as well as because of the incomplete transfer system in the health care services. To improve diagnosis and treatment ability of pulmonologists in second-level PHs, an intervention that provided training combined with spirometry equipment was carried out in three PHs from six second-level PHs. The aim of this follow-up study was to evaluate the changes associated with COPD-related health resources allocation and the effect of the intervention 4 years later.Methods: The data regarding the availability of spirometers, inhalation agents for COPD, and COPD-related health care education for local residents were collected from 57 PHs in 2009 and 48 PHs in 2013. Pulmonologists working in these PHs were asked to complete a questionnaire individually.

    We have investigated the interactions between economic growth and industrial wastewater discharge from 1978 to 2007 in China's Hunan Province using co-integration theory and an error-correction model. Two main economic growth indicators and four representative industrial wastewater pollutants were selected to demonstrate the interaction mechanism. We found a long-term equilibrium relationship between economic growth and the discharge of industrial pollutants in wastewater between 1978 and 2007 in Hunan Province. The error-correction mechanism prevented the variable expansion for long-term relationship at quantity and scale, and the size of the error-correction parameters reflected short-term adjustments that deviate from the long-term equilibrium. When economic growth changes within a short term, the discharge of pollutants will constrain growth because the values of the parameters in the short-term equation are smaller than those in the long-term co-integrated regression equation, indicating that a remarkable long-term influence of economic growth on the discharge of industrial wastewater pollutants and that increasing pollutant discharge constrained economic growth. Economic growth is the main driving factor that affects the discharge of industrial wastewater pollutants in Hunan Province. On the other hand, the discharge constrains economic growth by producing external pressure on growth, although this feedback mechanism has a lag effect. Economic growth plays an important role in explaining the predicted decomposition of the variance in the discharge of industrial wastewater pollutants, but this discharge contributes less to predictions of the variations in economic growth.

    In order to understand the status of fixed ammonium, fixed ammonium content, maximum capacity of ammonium fixation, and their influencing factors in major types of tillage soils of Hunan Province, China, were studied with sampling on fields, and laboratory incubation and determination. The main results are summarized as follows: (1) Content of fixed ammonium in the tested soils varies greatly with soil use pattern and the nature of parent material. For the paddy soils, it ranges from 135.4 ± 57.4 to 412.8±32.4 mg kg-1, with 304.7±96.7 mg kg-1 in average; while it ranges from 59.4 to 435.7 mg kg-1, with 230.1 ± 89.2 mg kg1 in average for the upland soils. The soils developed from limnic material and slate had higher fixed ammonium content than the soils developed from granite. The percentage of fixed ammonium to total N in the upland soils is always higher than that in the paddy soils. It ranges from 6.1 ± 3.6% to 16.6 ±4.6%, with 14.0% ± 5.1% in average for the paddy soils and it amounted to 5.8 ±2.0% to 40.1 ± 17.8%, with 23.5 ± 14.2% in average for upland soils. (2) The maximum capacity of ammonium fixation has the same trend with the fixed ammonium content in the tested soils. For all the tested soils, the percentage of recently fixed ammonium to maximum capacity of ammonium fixation is always bellow 20% and it may be due to the fact that the soils have high fertility and high saturation of ammonium-fixing site. (3) The clay content and clay composition in the tested soils are the two important factors influe ncing their fixed ammonium content and maximum capacity of ammonium fixation. The results showed that hydrous mica is the main 2:1 type clay mineral in <0.02 mm clay of the paddy soils, and its content in 0.02-0.002 mm clay is much higher than that in < 0.002 mm clay of the soils. The statistical analysis showed that both the fixed ammonium content and the maximum capacity of ammonium fixation of the paddy soils were positively correlated with

    By using error correction model, I conduct co-integration analysis on the research of the relationship between the per capita practical consumption and per capita practical disposable income of urban residents in Hunan Province from 1978 to 2009. The results show that there is a co-integration relationship between the per capita practical consumption and the practical per capita disposable income of urban residents, and based on these, the corresponding error correction model is established. Finally, corresponding countermeasures and suggestions are put forward as follows: broaden the income channel of urban residents; create goods consuming environment; perfect socialist security system.

    The legends of Cave Gods refer to the oral texts focusing on the supernatural beings, ghosts, monsters, goblin animals. Such legends, with their rich contents, have displayed a unique natural environment and historical and cultural environment of Western Hunan. They are essential texts which represent people's views of life, ethics, religion, custom, arts, etc. This article, based on the existing texts of the Cave Gods legends, concludes that there are several cultural check and balance functions like "respecting the balance of the nature and ecology", "praising highly for social stability, unity and harmony", "entertaining the public of Western Hunan", "interpreting the acts of beliefs in witches and ghosts", which make a solid foundation for the a further exploration and research on the legend of Cave Gods in Western Hunan.%湘西洞神传说是指以湘西洞穴中的神仙、鬼怪、妖兽为传说核的民间口述文本。这些传说以丰富的内容展现了湘西地区独特的自然环境和历史文化环境,是表现民间生活观、伦理观、宗教观、风俗观和艺术观等价值观的重要文本形式。本文立足于湘西洞神传说现有的传说文本进行研究,总结出“对自然生态平衡行为的推崇”、“对社会安定团结和谐行为的褒扬”、“对湘西民众生活的娱乐”、“对崇巫信鬼行为的解释”等几个湘西洞神传说的重要文化制衡作用,为进一步发掘和研究湘西洞神传说奠定基础。

    The occurrence situation and damages of grape fanleaf disease in main grape production areas in Hunan province, such as northwest Hunan, southern Hunan, middle Hunan and western Hunan, were investigated, and the suspected disease plants from each area were detected by biological method and molecular biological method. The results showed that in main grape production areas of Hunan province, many grape varieties occurred grape fanleaf disease, such as Xiahei-seedless, Red-earth, Jinxing-seedless, Golden-finger, etc., but the Vitis davidii var. davidii from western Hunan showed a certain resistance to the grape fanleaf disease. The symptoms of the grape fanleaf disease generally showed as follows: the leaf was degreening and yellowing; the serrate leaf margin turned to sharpening or out-of-shape; the growth of grape plants was influenced seriously, thus weakening tree vigour, reducing yield and decreasing fruit quality. The biological detection results indicated that among 54 collected samples, 52% samples presented systemic mottle and distortion in Qianrihong and Benshi tobacco varieties.

    An increase in the incidence of hand, foot and mouth disease (HFMD) cases has been observed in the Hunan province of mainland China since 2009 with a particularly higher level of severe cases in 2010-2012. Intestinal viruses of the picornaviridae family are responsible for the human syndrome associated with HFMD with enterovirus 71 (EV71) and Coxsackievirus A16 (Cox A16) being the most common causative strains. HFMD cases associated with EV71 are generally more severe with an increased association of morbidity and mortality. In this study, the etiology surveillance data of HFMD cases in Hunan province from March 2010 to October 2012 were analyzed to determine if there is a statistically relevant linear correlation exists between the detection rate of EV71 in mild cases and the proportion of severe cases among all HFMD patients. As the cases progressed from mild to severe to fatal, the likelihood of EV71 detection increased (25.78%, 52.20% and 84.18%, respectively). For all cases in the timeframe evaluated in this study, the presence of virus was detected in 63.21% of cases; among cases showing positivity for virus, EV71 infection accounted for 50.14%. These results provide evidence to support the observed higher morbidity and mortality associated with this outbreak and emphasizes the importance of early detection in order to implement necessary prevention measures to mitigate disease progression.

    Bailong Cave with its well-developed Middle Triassic calcareous dolomite's system was opened as a show cave for visitors in 1988. The speleothem scenery has been strongly weathered as white powder on the outer layers. Study of the cave winds, permeability of soil-rock system and the chemical compositions of the dripping water indicated: (1) The cave dimension structure distinctively affects the cave winds, which were stronger at narrow places. (2) Based on the different soil grain size distribution, clay was the highest in composition in the soil. The response sense of dripping water to the rainwater percolation was slow. The density of joints and other openings in dolomite make the dolomite as mesh seepage body forming piles of thin and high columns and stalactites. (3) Study of 9 dripping water samples by HYDROWIN computer program showed that the major mineral in the water was dolomite.

    Full Text Available Abstract Background There are growing concerns regarding inequities in health, with poverty being an important determinant of health as well as a product of health status. Within the People's Republic of China (P.R. China, disparities in socio-economic position are apparent, with the rural-urban gap of particular concern. Our aim was to compare direct and proxy methods of estimating household wealth in a rural and a peri-urban setting of Hunan province, P.R. China. Methods We collected data on ownership of household durable assets, housing characteristics, and utility and sanitation variables in two village-wide surveys in Hunan province. We employed principal components analysis (PCA and principal axis factoring (PAF to generate household asset-based proxy wealth indices. Households were grouped into quartiles, from 'most wealthy' to 'most poor'. We compared the estimated household wealth for each approach. Asset-based proxy wealth indices were compared to those based on self-reported average annual income and savings at the household level. Results Spearman's rank correlation analysis revealed that PCA and PAF yielded similar results, indicating that either approach may be used for estimating household wealth. In both settings investigated, the two indices were significantly associated with self-reported average annual income and combined income and savings, but not with savings alone. However, low correlation coefficients between the proxy and direct measures of wealth indicated that they are not complementary. We found wide disparities in ownership of household durable assets, and utility and sanitation variables, within and between settings. Conclusion PCA and PAF yielded almost identical results and generated robust proxy wealth indices and categories. Pooled data from the rural and peri-urban settings highlighted structural differences in wealth, most likely a result of localized urbanization and modernization. Further research is needed

    Full Text Available The authors present more data about the speleological aspect of the Sterkfontein Cave, famous for its bone breccia which yielded abundant hominid remains. They also briefly review the previous voluminous studies by numerous authors, which are mainly dealing with the paleontology, stratigraphy and sedimentology of the breccia. The present investigations were oriented to hitherto poorly investigated aspects such as detail mapping of the cave, its country rock stratigraphy and recording the underground extension of the basal part of the breccia body. The cave consists of a complex network of phreatic channels, developed along joints in Neoarchaean cherty dolostone over a restricted surface of 250x250m. The combined length of all passages within this area amounts to 5,23km. The system extends over a height of about 50m and the dry part of it is limited downwards by the water-table appearing as numerous static pools. The fossiliferous breccia (= Sterkfontein Formation forms an irregular lenticular mass 75x25m horizontally by 40m vertically, which is included within the passage network. It crops out at surface and in the cave, and resulted from the filling of a collapse chamber, which was de-roofed by erosion. The present investigation confirmed that the cave and the Sterkfontein Formation are part of a single speleogenetic event. The breccia resulted from cavity filling by sediments introduced from a pit entrance, whereas many of the phreatic passages around it, which are developed at the same elevation, were only partly filled or remained entirely open up to present. This filling took place mainly in a vadose environment. Taking into account the age of the Sterkfontein Formation (>3,3-1,5 My, from base to top, the geomorphic evolution of the landscape and the context of other caves in the region, it seems that the cave might have started to form 5 My ago. It has been continuously developing up to present as a result of a slow drop of the water-table.

    The LA-ICPMS zircon U-Pb geochronology of three typically Indosinian granitic plutons yielded weighted mean 206Pb/238U ages of 214.1±5.9 Ma and 210.3±4.7 Ma for the biotite monzonitic granites from the Xiema and Xiangzikou plutons in Hunan Province, and 205.3±1.6 Ma for biotite granite from the Napeng pluton, western Guandong Province, respectively, showing a similar late Indosinian age of crystallization. In combination with other geochronological data from Indosinian granites within the South China Block (SCB), it is proposed that those late Indosinian granites with an age of ~210 Ma and the early Indosinian granites (230-245 Ma) have the similar petrogenesis in identical tectonic setting. The Indosinian granites within the SCB might be the products of anatexis of the thickening crust in a compressive regime. These data provide a further understanding for the temporal and spatial distribution of the Indosinian granites and the dynamic evolution of the SCB.

    为了充分调动农民的种粮积极性,达到同工同酬的目的,通过大量现场调研并对湖南省典型地区生产成本、销售成本和政府补贴的综合计算和分析提出具有可操作性的直接补贴参考标准。结果表明,早、中、晚稻的生产成本存在明显的类型差异性和地区差异性,特别是地区差异非常显著;最高地区的日工资为71元,还未达到市场工资标准,但已是最低地区的2.6倍;为了达到同工同酬的目标,有必要实施地区差异性补贴。拟将湖南省各地区分为4个梯度,进行差异性补贴,使日工资基本接近,从而缩小农村内部的贫富差距,提高农民生产的积极性。%To stimulate farmers’initiatives effectively and to make sure that people get the same amount of wage for doing the same kind of work,a criterion of direct subsidies was provided on the basis of lots of field work.Calculation and analysis of the typical areas of Hunan Province based on the production cost,cost of sales and government subsidies indicated that in terms of production cost of early,middle and late rice,significant differences in types and areas were found.Differences among areas were especially noticeable.The highest daily wage of some areas,though failed to reach the standard wage set by the market,was 2.6 times that of other areas,which was at the bottom.Therefore,to make sure that people in different areas get the same amount of wage for doing the same kind of work,it is quite necessary to implement the differentiated subsidy policy.And at this stage,in order to narrow the financial gap among farmers and to stimulate farmers' initiatives,this program plans to divide Hunan Province into four districts of various production-cost gradients,so as to implement the differentiated subsidy policy well.

    Objectives To study characteristics of psychosomatic symptoms related to sterilization,to find out risk factors and their roles ascribed to psychosomatic symptoms, and toestablish a mathematic model for screening out susceptible women.Methods: This study enrolled 776 women in rural area at three counties of Linxiang,Qiyang, Changsha of Hunan province in China between February 1990 and April1992. Brief Neurosis Screening Scale (BNSS), Symptom Checklist 90 (SCL-90),sensitivity to pain, suggestibility were used to indicate subjects' psychological status.Logistic regression model and retrograde discriminant analysis were applied to developa mathematical model.Results: Prevalence of psychosomatic reactions or symptoms was 54. 8% before steril-ization, 26. 6% at three months and 16. 4% at one year after operation respectively.Psychosomatic symptoms were verified to be the result of joint effects of multiple riskfactors. The following risk factors were associated with postoperative symptoms:anger-hostility (RR= 33. 71), high suggestibility (RR= 4. 53), high neuroticism (RR= 3. 44), sensitivity to pain (RR = 2. 14) and operative sites (RR = 2. 05). A mathe-matical model to estimate the probability of developing psychosomatic symptoms in ster-ilization was established.Conclusions: More than half of women suffered from psychosomatic reactions beforeoperation, and some of them did not recover after operation. The postoperative psycho-somatic symptoms are the joint effect of multiple risk factors.

    A land use- and geographical information system-based framework was presented for potential human health risk analysis using soil sampling data obtained in Zhuzhou City, Hunan Province, China. The results show that heavy metal content in soil significantly differs among different land use types. In total, 8.3% of the study area has a hazard index (HI) above the threshold of 1.0. High HIs are recorded mainly for industrial areas. Arsenic (>87%) and the soil ingestion pathway (about 76%) contribute most to the HI. The mean standardized error and root-mean-square standardized error data indicate that the land use-based simulation method provides more accurate estimates than the classic method, which applies only geostatistical analysis to entire study area and disregards land use information. The findings not only highlight the significance of industrial land use, arsenic and the soil ingestion exposure pathway, but also indicate that evaluating different land use-types can spatially identify areas of greater concern for human health and better identify health risks.

    The Sangzhi-Shimen synclinorium, which is in the western margin region of the Hunan-Hubei Province and as the southeast part of the middle Yangtze platform, is a second-level tectonics unit in the south of this region.Along the profile, it can be divided into 5 third-level structure belts. By the comprehensive interpretation of seismic data and magnetotelluric (MT) sounding data, it is found that the surface structure is not in accordance with that of the underground, and this un-coordination can be conducted by many decollement surfaces between the layers.There are three periods of deformation in its geo-history in this region: before the early Yanshan stage, during the early Yanshan stage and after the early Yanshan stage, while the main deformation period is during the early Yanshan stage. And the mechanism of deformation is the thrust faults in basement, which are controlled by many decollements, in addition to the decollement of the cap-rock.

    A total of 219 agricultural soil and 48 vegetable samples were collected from the midstream and downstream of the Xiangjiang River (the Hengyang-Changsha section) in Hunan Province. The accumulation characteristics, spatial distribution and potential risk of heavy metals in the agricultural soils and vegetables were depicted. There are higher accu- mulations of heavy metals such as As, Cd, Cu, Ni, Pb and Zn in agricultural soils, and the contents of Cd (2.44 mg kg-1), Pb (65.00 mg kg-1) and Zn (144.13 mg kg-1) are 7.97, 3.69 and 1.63 times the corresponding background contents in soils of Hunan Province, respectively. 13.2% of As, 68.5% of Cd, 2.7% of Cu, 2.7% of Ni, 8.7% of Pb and 15.1% of Zn in soil sam- ples from the investigated sites exceeded the maximum allowable heavy metal contents inthe China Environmental Quality Standard for Soils (GB15618-1995, Grade II). The pollution characteristics of multi-metals in soils are mainly due to Cd. The contents of As, Cd, Cu, Pb and Zn in vegetable soils are significantly higher than the contents in paddy soils. 95.8%, 68.8%, 10.4% and 95.8% of vegetable samples exceeded the Maximum Levels of Contami- nants in Foods (GB2762-2005) for As, Cd, Ni and Pb concentrations, respectively. There are significantly positive correlations between the concentrations of Cd, Pb and Zn in vegetables and the concentrations in the corresponding vegetable soils (p<0.01). It is very necessary to focus on the potential risk of heavy metals for food safety and human health in agricultural soils and vegetables in the midstream and downstream of the Xiangjiang River, Hunan Province of China.

    Full Text Available BACKGROUND: Access to health care is a major requirement in improving health and fostering socioeconomic development. In the People's Republic of China (P.R. China, considerable changes have occurred in the social, economic, and health systems with a shift from a centrally planned to a socialist market economy. This brought about great benefits and new challenges, particularly for vertical disease control programs, including schistosomiasis. We explored systemic barriers in access to equitable and effective control of schistosomiasis. METHODOLOGY: Between August 2002 and February 2003, 66 interviews with staff from anti-schistosomiasis control stations and six focus group discussions with health personnel were conducted in the Dongting Lake area, Hunan Province. Additionally, 79 patients with advanced schistosomiasis japonica were interviewed. The health access livelihood framework was utilized to examine availability, accessibility, affordability, adequacy, and acceptability of schistosomiasis-related health care. PRINCIPAL FINDINGS: We found sufficient availability of infrastructure and human resources at most control stations. Many patients with advanced schistosomiasis resided in non-endemic or moderately endemic areas, however, with poor accessibility to disease-specific knowledge and specialized health services. Moreover, none of the patients interviewed had any form of health insurance, resulting in high out-of-pocket expenditure or unaffordable care. Reports on the adequacy and acceptability of care were mixed. CONCLUSIONS/SIGNIFICANCE: There is a need to strengthen health awareness and schistosomiasis surveillance in post-transmission control settings, as well as to reduce diagnostic and treatment costs. Further studies are needed to gain a multi-layered, in-depth understanding of remaining barriers, so that the ultimate goal of schistosomiasis elimination in P.R. China can be reached.

    Background Juvenile violent offending is a serious worldwide public health issue. Objective The study examined whether the Structured Assessment of Violence Risk in Youth (SAVRY) can be used to predict violent reoffending in Chinese male juvenile offenders, and to determine which risk/protective domains (items) are associated with violent recidivism. Methods A total of 246 male juvenile offenders were recruited. SAVRY domains were scored by trained raters based on file review and interviews with participants and their legal guardians. Information on further arrests, charges, or convictions for violent offences were collected from police records over a five year follow-up. Results Over the course of the five year follow-up periods, 63 (25.6%) juvenile offenders were re-arrested for a further violent reoffence. Receiver Operating Characteristic (ROC) analyses showed Areas Under the Curve (AUCs) ranging from 0.60 to 0.68 for the SAVRY total, risk and protective score domains. Univariate logistic regression analysis showed that 7 of the 30 SAVRY items were significantly associated with reoffending; explaining 36.2% of the variance. Backward stepwise multiple logistic regression analysis showed the independently predictive items were items 2 (‘history of non-violent offending’), 17 (‘negative attitudes’), 18 (‘risk-taking/impulsivity’), and 20 (‘anger management problems’). Together these four items explained 25.0% of the variance in reoffending. Conclusions The results suggested that the SAVRY can be meaningfully used to inform the development and evaluation of effective violence risk assessment and management approaches for male juvenile offenders detained in a Youth Detention Center in Hunan province, China.

    One active stalagmite from the Water Cave in Liaoning Province contains growth layers of three sizes. Based on thermal ionization mass spectrometry 230Th dating, we found that middle size layers are annual layers, with each middle layer consisting of one narrow dark layer and a wide bright layer. The small layers within middle layers are sub-annual layers and the large layers are multi-year layers. Based on the layer-counting method, we established a high-resolution time scale for layer thickness. Our results reveal two dramatic century-scale climate cycles over the past 1000 years in this region.

    Site PP13B is a cave located on the steep cliffs of Pinnacle Point near Mossel Bay in Western Cape Province, South Africa. The depositional sequence of the cave, predating Marine Isotopic Stage 11 (MIS 11) and continuing to present, is in the form of isolated sediment exposures with different depositional facies and vertical and lateral variations. Micromorphological analysis demonstrated that a suite of natural sedimentation processes operated during the development of the sequence ranging from water action to aeolian activity, and from speleothem formations to plant colonization and root encrustation. At the same time, anthropogenic sediments that are mainly in the form of burnt remains from combustion features (e.g., wood ash, charcoal, and burnt bone) were accumulating. Several erosional episodes have resulted in a complicated stratigraphy, as discerned from different depositional and post-depositional features. The cave is associated with a fluctuating coastal environment, frequent changes in sea level and climate controlled patterns of sedimentation, and the presence or absence of humans.

    Important to the evolution of Danxia landforms is how the rock cliffs are in large part shaped by rock collapse events, ranging from small break offs to large collapses. Quantitative research of Danxia landform evolution is still relatively young. In 2013-2014, Chinese and Slovak researchers conducted joint research to measure deformation of two large rock walls. In situ measurements of one rock wall found it to be stable, and Ps-InSAR measurements of the other were too few to be validated. Research conducted this year by Chinese researchers modeled the stress states of a stone pillar at Mt. Langshan, in Hunan Province, that toppled over in 2009. The model was able to demonstrate how stress states within the pillar changed as the soft basal layer retreated, but was not able to show the stress states at the point of complete collapse. According to field observations, the back side of the pillar fell away from the entire cliff mass before the complete collapse, and no models have been able to demonstrate the mechanisms behind this behavior. A further understanding of the mechanisms controlling rockfall events in Danxia landforms is extremely important because these stunning sceneries draw millions of tourists each year. Protecting the tourists and the infrastructure constructed to accommodate tourism is of utmost concern. This research will employ a UAV to as universally as possible photograph a stone pillar at Mt. Langshan that stands next to where the stone pillar collapsed in 2009. Using the recently developed structure-from-motion technique, a 3D model of the pillar will be constructed in order to extract geometrical data of the entire slope and its structural fabric. Also in situ measurements will be taken of the slope's toe during the field work exercises. These data are essential to constructing a realistic discrete element model using the 3DEC code and perform a kinematic analysis of the rock mass. Intact rock behavior will be based on the Mohr Coulomb

    Objective: To describe the status of, and to identify the factors associated with, complementary feeding among infants and young children aged 6- 23 months in poor rural areas of Hunan Province, China. Methods: A total of 8 735 infants and young children aged 6- 23 months from 30 poor rural counties in the Wuling and Luoxiao Mountains in Hunan Province were selected by township-level probability-proportional-to-size sampling in August 2015. Questionnaires were used to collect information on the feeding status of the infants in the previous 24 hours, along with personal/family information. The qualified rate of minimum dietary diversity (MDD), the minimum meal frequency (MMF) and the minimum acceptable diet (MAD) were calculated according to the WHO indicators for assessing infant and young child feeding practices. Multi non-conditional logistic regression models were used to analyze factors associated with complementary feeding among infants and young children aged 6- 23 months. Results: The findings indicated that 73.9% (6 452/8 735) of infants and young children aged 6-23 months received the minimum dietary diversity, 81.6% (7 124/8 735) of infants and young children aged 6- 23 months received the minimum meal frequency and 49.0% (4 276/8 735) of infants and young children aged 6- 23 months received an acceptable diet. Compared with the boys, the OR for the MMF and MAD for the girls were 1.15 and 1.11, respectively. Compared with the 6-11 month group, the OR for the MDD for the 12-17 month and 18-23 month groups were 0.41 and 0.38, respectively; the OR for the MMF for the 12-17 month and 18-23 month groups were 1.53 and 2.46, respectively; and the OR for the MAD for the 12-17 month and 18-23 month groups were 0.60 and 0.60, respectively. Compared with the Han ethnic group, the OR for the MDD, MMF and MAD for the Miao ethnic group were 1.43, 1.72 and 1.56, respectively; for the Tujia ethnic group were 2.21, 2.02 and 2.11, respectively; and for the Dong ethnic

    2007-11-01

    Full Text Available The Stone Age of South Africa is an area of study due for a renaissance, and there is a real need for unification of the extant evidence. As a beginning to this, new methodologies have been proposed. This paper tackles the issue of symmetry, specifically the subjectivity involved in by-eye judgements. Assumptions of subjectivity, however, are not proof: presented here is a critical analysis of the inherent bias of by-eye symmetry judgements. Ultimately it is clear that the method contains a level of subjectivity which strips it of any analytical value. The by-eye judgement of symmetry is replaced by the more robust Flip Test computer program, and a brief study is made of the Large Cutting Tools (LCT at a vitally important, yet often overlooked, site dating from the Pleistocene in South Africa, the Cave of Hearths, Limpopo province. The corollary is that the symmetry present in the Cave of Hearths Large Cutting Tools can be studied with some measure of confidence: suggestions are made regarding the nature of tool typologies and the knappers’ ultimate focus on tip shape and utility.

    Understanding the responses of fluorescence spectral characteristics of cave drip waters to modern environment and climate changes is key to the reconstructions of environmental and climatic changes using fluorescence spectral characteristics of speleothems. The fluorescence spectral characteristics of dissolved organic carbon (DOC) in four active cave systems were analyzed with a three-dimensional (3D) fluorescence spectral analysis method. We found that the fluorescence types of DOC were mainly of fulvic-like and protein-like fluorescences, both in soil waters and cave drip waters. The intensity of fulvic-like fluorescence was positively correlated with the concentrations of DOC, suggesting that the DOC of cave drip waters was derived from the overlying soil layer of a cave system. Compared with the other cave systems, the variation range of the excitation and emission wavelengths for fulvic-like fluorescence of cave drip waters in Liangfeng cave system that had forest vegetation was smaller and the excitation wavelength was longer, while its fluorescence intensity varied significantly. By contrast, the excitation and emission wavelengths and fluorescence intensity for that in Jiangjun cave system that had a scrub and tussock vegetation showed the most significant variation, while its excitation wavelength was shorter. This implies that the variation of vegetation overlying a cave appears to be a factor affecting the fluorescence spectral characteristics of cave drip waters.

Compared with 2001, the emergy output of planting industry was (4.10E+22) sej in 2010 which occupied 63.09% of the total agricultural emergy output and got an increase of 2.93 percentage points, while the emergy output of stock farming got a decrease of 2.87 percentage points. The growth of fishery emergy output was not in conformity with the characteristics of Dongting Rim in Hunan. From the contrast between emergy output and economic output, we could find that the economic return ratio of planting industry and fishery industry were lower than those of forestry industry and stock farming industry, which indicated that

    Based on 33 U/Th dates and 1020 oxygen isotopic data from stalagmite Y1 from Yamen Cave, Guizhou Province, China, a record of the Asian Summer Monsoon (ASM) was established. The record covers the last deglaciation and the early Holocene (from 16.2 to 7.3 ka BP) with an average oxygen isotope resolution of 9 years. The main millennial-scale deglacial events first identified in Greenland (Greenland Interstadial Events: GIS 1e through GIS 1a) and later in China are clearly present in the Y1 record. By analogy to earlier work, we refer to these as Chinese Interstadials (CIS): CIS A.1e to CIS A.1a. The onset of these events in Y1 δ18O records are nominally dated at: 14750±50, 14100±60, 13870±80, 13370±80, and 12990±80 a BP. The end of CIS A.1a or the beginning of the Younger Dryas (YD) event is nominally at 12850±50 a BP and the end of the YD dates to 11500±40 a BP. The δ18O values shift by close to 3‰ during the transition into the Bφlling-Allerφd (BA, the onset of CIS A.1e) and at the end of the YD. Comparisons of Y1 to previously published early Holocene records show no significant phase differences. Thus, the East Asia Monsoon and the Indian Monsoon do not appear to have been out of phase during this interval. The Y1 record confirms earlier work that suggested that solar insolation and North Atlantic climate both affect the Asian Monsoon.

    Most researchers believe that anatomically modern humans (AMH) first appeared in Africa 160-190 ka ago, and would not have reached eastern Asia until ∼50 ka ago. However, the credibility of these scenarios might have been compromised by a largely inaccurate and compressed chronological framework previously established for hominin fossils found in China. Recently there has been a growing body of evidence indicating the possible presence of AMH in eastern Asia ca. 100 ka ago or even earlier. Here we report high-precision mass spectrometric U-series dating of intercalated flowstone samples from Huanglong Cave, a recently discovered Late Pleistocene hominin site in northern Hubei Province, central China. Systematic excavations there have led to the in situ discovery of seven hominin teeth and dozens of stone and bone artifacts. The U-series dates on localized thin flowstone formations bracket the hominin specimens between 81 and 101 ka, currently the most narrow time span for all AMH beyond 45 ka in China, if the assignment of the hominin teeth to modern Homo sapiens holds. Alternatively this study provides further evidence for the early presence of an AMH morphology in China, through either independent evolution of local archaic populations or their assimilation with incoming AMH. Along with recent dating results for hominin samples from Homo erectus to AMH, a new extended and continuous timeline for Chinese hominin fossils is taking shape, which warrants a reconstruction of human evolution, especially the origins of modern humans in eastern Asia.

    It is very import to delimitate red line of ecological protection for territorial spatial planning. This paper proposed a quantitative framwork to delimit red line of ecological protection. First, we defined biodiversity, flood storage, conservation of water and soil, headwater conservation and desertification control as the main factors to ecological problems at the provincial scale. Then, based on the theories of ecological service and security, core elements were chosen for analyzing the ecological problems referring to the requirements of macro decision-making, participatory “bottom-up” method was further utilized to map the ecological red line. In this model, main ecological problems and most sensitive areas in territorial space were identified by the means of“top-down”method. And then the red line of ecological protection was delimitated by using“bottom-up” model integrating GIS with RS. Hunan Province was selected as the case study area to delimit the red line of ecological protection using the proposed framework. Three scenarios (i.e. ecological protection at low level, at medium level, and at high level, respectively) were set for analyzing the distribution of each individual ecological element. Results indicate that medium-level protection scenario is befitting for delimiting red line from the perspective of biodiversity. Ecological corridors is required to be further conserved on the basis of present conservation areas;whereas low-level protection scenario was selected for flood storage, Dongting Lake and its inundated area should be included in the protection region;and the spatial pattern of headwater conservation shows great difference. The large-scale mountains in the east, west and south parts have high values while the hills in the central part as well as the plain in the north show low values of headwater conservation; As for conservation of water and soil, mountains such as the Wuling, Xuefeng in the west and the Luoxiao in the east

    湖南省老年人口规模迅速膨胀,高龄、空巢现象日益严重,养老服务潜在需求旺盛。但是,有效需求和供给不足。养老服务支付能力不足、行业标准缺失、长期护理服务和专业护理人员欠缺、投资运营效率不高诸多因素严重制约着目前湖南养老服务业的发展。因此,面对发展困境,我们应从提高老年人收入水平、完善行业标准、构建长期护理保险制度以及提高养老服务业的市场化程度等方面来寻求突破口。%In Hunan province, the potential demand of old-age care service is increasingly growing due to the elderly population scale expanded rapidly and serious phenomena of older age, empty nest of people. However, in fact, effective demand and supply are insufficient. Many factors seriously restrict the development of old-age care service industry, such as lacking of the ability to pay pension services, industry standards, long-term care services and professional nurses and the low efficiency of investment operating. Therefore, faced with a dilemma, we should improve the level of income in the elderly, improve industry standards, build long-term care insurance system, and increase the degree of marketization for old-age care services in order to boost the development of old-age service industry.

    Objective To analyze the epidemic trend and current status of rabies control in Hunan Province from 1996 to 2010. Methods Rabies case reports were collected to retrospectively analyze the epidemic trend. Direct immunofluores-cence assay (DFA) and nested PCR were employed to detect the monitoring samples, including brain tissues of dogs and saliva, cerebrospinal fluid, serum or urine which were collected from the rabies patients from 2008 to 2010. Genetic characteristics of rabies virus were also analyzed. We investigated the current situation of disposal after exposure to rabies among rural residents by sampling survey. Results The rabies case reports in Hunan Province were increasing continuously from 1996 until reaching to the peak in 2004, and decreasing since 2007. Of the 2,437 tissue samples from the dogs' brain, 72 were positive under DFA and the positive rate was 2.95%. The DFA positive samples were redetected by RT- PCR and the positive rate was 0.94% (23/72). 104 samples of saliva, cerebrospinal fluid, serum and urine were detected by RT- PCR from the rabies patients, with 11 positives and the positive rate was 10.58%. All the isolated rabies viruses belonged to genotype I. More than 90 % rural residents knew about rabies, but only 20.1 % knew the high risk behaviors of rabies and 17.3% knew the prevention measures after exposure to rabies. 89.09% of the patients with level III exposure did not use rabies passive immune agents. Conclusions The epidemic situation of rabies in Hunan Province has been decreasing with the implementation of a series of measures. Lack of correct understanding of rabies and the poor economic condition are the main reasons for nonstandard disposal after exposure to rabies.%目的 分析1996 -2010年湖南省狂犬病的流行趋势及防治现状.方法 利用疫情报告资料回顾分析狂犬病的流行趋势;采用直接免疫荧光法(DFA)和巢式PCR等方法对监测标本进行病原学检测及病毒基因特征分析

    contribute to optimizion of rice cultivation management for adapting to the changing conditions. In this study, we selected the recorded rice phonological observations at 10 agro-meteorological experiment stations, and the corresponding weather and statistical yields from 1980–2012 in Hunan Province, China. These data were used to analyze rice sensitivity to climate change using a panel model combined with multiple regression methods. The relationship of climate and yield trend was computed with the least square method, and the possible relationship between climatic factors and double-rice yield was analyzed by partial correlation analysis. The results showed that the double-rice region in Hunan Province experienced a warming trend over the last three decades, and the average temperature during the early rice and late rice seasons were 0.47 and 0.33 oC/(10a) higher. An increase in temperature of 0.76 oC/(10a) was observed during the vegetative stage of the early rice season, while the late rice season experienced a relatively slower increase in temperature. Precipitation and radiation during the growth stage of early rice tended to increase unnoticeable, but radiation in the vegetative stage and the reproductive stage of early rice changed with the trend-0.40 and 0.40 MJ/(m2·d·10a), while the trend was opposite for the late rice. Yield changes in the early rice were significantly correlated with precipitation and radiation during the ripening stage and the whole growth stage (P<0.01), but only the average temperature was significantly correlated to the yield for the late rice (P<0.05). Whatever the model adopted, the yield sensitivity of double-rice to climate change showed great differences among different growth stages, ranging from -280.11 to 118.20 kg/hm2. Temperature, precipitation and radiation in the vegetative stage were most sensitive to the yield for both the early rice and late rice. The rising temperature increased yield of the early rice, while we observed

    湘东南花岗闪长质岩石以高K2O/Na2O, K2O+Na2O>6.0%为特征, 属高钾钙碱性系列岩石, 其形成主要受部分熔融作用制约; 岩石稀土元素富集, 铕负异常不明显, δEu=0.71~0.89; 富集大离子亲石元素, Nb-Ta亏损, P、Ti或亏损或不亏损, 具岛弧型岩浆作用微量元素分配模式, 属板内钾质岩石, 源区可能存在早期俯冲组分改造的岩石圈富集地幔组分, 或是源于软流圈的岩浆与中下地壳混合作用的产物; 其形成与该带中生代早期岩石圈的伸展-减薄作用有关。%Mesozoic granodioritic intrusions occurring in Southeast Hunan Province belong to high-K calc-alkaline series with high K2O/Na2O ratios and K2O+Na2O>6.0%. The chondrite-normalized REE patterns are characterized by LREE enrichment with weakly negative Eu anomalies (δEu=0.71~0.89), different from those of Mesozoic granitic plutons in which intensely negative Eu anomalies were observed. In the primitive mantle-normalized spidergrams, they are enriched in LILE and LREE with significant Nb-Ta depletion. Additionally, some of the rocks demonstrate a clear Ti and P depletion while it is inapparent for other samples. The geochemical characteristics of the Mesozoic granodioritic intrusions suggest the involvement of an enriched lithosphere mantle that had been modified by ancient recycling continental crust, or source mixing between asthenosphere-derived basalts and the lower/middle crust. Combining with the regional tectonic evolution, it is reasonable that the formation of Mesozoic granodioritic intrusions should be related to the early Mesozoic lithospheric extension and thinning.

    In recent years,acid rain caused by air pollution in China is worsening,and the impact caused by it can not be ignored for our living environment. The project based on the concrete corrosion mechanism studies the degree of acid rain harm to concrete durability in central region of Hunan Province and presents effective protective measures by analyzing trends of acidity,composition,rainfall and simulating the acid rain corrosion of concrete. The studies show that the impact of acid rain on the concrete can not be ignored. Concrete acid corrosion occurs mainly in general under the influence of acid rain,sulfate attack,car_bonation of soft water corrosion and concrete,etc. ,so that the film is formed on the surface of concrete,damage occurs,the deterioration of mechanical properties and neutral,largely influences durability of concrete and makes the concrete compressive reduce significantly. In order to reduce and avoid adverse impacts of acid rain,erosion prevention and treatment of concrete are very significant.%近年来我国大气污染造成的酸雨危害日益严重,对环境造成了不可忽视的影响。本项目分析湖南省中部地区酸雨酸度、成分、降雨量的变化趋势,基于酸雨对混凝土的腐蚀机理,通过模拟酸雨腐蚀的实验方法,研究酸雨对湖南省中部地区混凝土耐久性的危害程度并提出有效的防护措施。试验研究表明:酸雨对混凝土的影响是不容忽视的。混凝土在酸雨的影响下主要发生一般的酸类腐蚀、硫酸盐腐蚀、软水腐蚀和混凝土的碳化作用等,使得混凝土表面生成薄膜,出现损伤,力学性能劣化和中性化,很大程度上影响了混凝土的耐久性。经过试验得出混凝土的抗压性能明显降低。为了减轻和避免工程实际中由于酸雨的危害产生的不良影响,防治混凝土受酸雨侵蚀显得尤为重要。

    In order to find out the genesis of the extraordinary debris flow disaster which took place in Hefangou gully of Hunan Province, where is a wet area of low seismic intensity, on June 10th in 2011, the drought grade of Hefangou Basin before the dis-aster was determined and the effect of lasting drought on the physical and mechanical characters of the granite residual soil was analyzed on the basis of field investigation and laboratory test. Besides, the rainfall quantity and time required to saturate the granite residual soil was calculated. Then the genesis of the debris flow was obtained: the vertical layered characteristic of the granite residual soil determined that the soil can easily start from the surface with high content of fine particles;early long dura-tion drought cracked the soil structure and speeded up the soil weathering along the part with high content of fine particles near ground surface, which increased the permeability of the soil;later heavy rainfall of short duration caused the rainwater to infiltrate along the cracks on the soil surface with fine soil particles moving, enriched and then formed the impermeable layer of soil, the strength of the soil decreased;with the continued heavy rainfall, the pore water pressure above the impermeable layer in the up-per soil soared to some extent, the soil failed and was liquefied to form the debris flow.%2011年6月10日,属湿润、低地震烈度区的湖南临湘贺畈沟暴发了历史罕见的特大泥石流灾害。为探明此次泥石流灾害的成因,在现场勘查工作的基础上,结合室内试验,划分了泥石流发生前贺畈沟流域的干旱等级,分析了长历时干旱对沟内花岗岩残积土物理力学性质的影响,计算了花岗岩残积土饱和所需的降雨量和时间,得出了此次泥石流灾害的成因:源区花岗岩残积土的垂直分层特征,决定了土体极易从细颗粒含量高的表层起动;前期长历时干旱导致土体表

    The Jaiojie Paleolithic Site is located in a karstic cave at Acheng, Haerbin Municipality in Heilongjiang Province. It is regarded as the oldest Paleolithic site in the province and also the northernmost one in China up to today. The geographic coordination at the cave entrance measured with the Global Positioning System ( GPS) is 45°21'07. 7"N and 127°05'16. 8"E, with an altitude of 183m. The cave deposits can be divided into 6 layers. Mammalian fossils were unearthed mainly from Layers 5 and 6 in the lower part of the cave deposits. As a Quaternary mammalian fauna,it is chronologically the earliest one in Heilongjiang Province and geographically the northernmost and easternmost in China. Layer 5 is composed of grayish green clay with some yellow clods, and the underlying Layer 6 composed of reddish yellow clay with breccia. Although the site was discovered in 1996 and systematically excavated in 1997,the fossils were never systematically described before 12 taxa were identified as follow; Mar mot a sp., Myospalax cf. Prosilurus, Ochotona sp., Lepus ( Eulagos) mandshuricus ( = Lepus wongi) , Mattes sp., Meles meles, Mustela sibirica, Ursus sp, Crocuta sp., Stephanorhinus kirchbergensis ( = Dicerorhinus mercki) ,Cervus(S. )nippon hortulorum,Capreolus capreolus manehuricus. The fossils from Layer 5 are mostly smaller forms such as Marmota sp.,Myospalax cf.prosilurus,Lepus(Eulagos) mandshuricus( = Lepus wongi) ,etc. ,and those from Layer 6 are mostly larger forms such as Stephanorhinus kirchbergensis, Cervus ( Sika) hortulorum, Crocuta etc. They are mostly northern forms. The fauna lacks typical cold forms such as Coelodonta and Mammuthus, and it was regarded as a fauna exsiting during the transition from temperate period to cold one in North Region. The comparison of fauna compositions shows that the Jiaojie fauna is close to that of the Middle Pleistocene Jinniushan and Miaohoushan faunas in Liaoning Province, the Late Pleistocene Xiaogushan and Gulongshan faunas

    The cultural deposits at pits T1 and T2 in Zhangkou Cave are intercalated with several flowstone layers. U-series dates show that the capping and 2nd flowstone layers are Holocene of age. The 4th and 5th flowstone layers are ca. 55 and 110 ka old respectively. The lithic artifacts bracketed by them provide unequivocal evidence for hominid presence during this time interval. The "temporal gap" of hominid fossil, widely quoted as in support of the out-of-Africa hypothesis, is most probably an artifact due to systematic errors of dating techniques. The infillings under 6th flowstone layer date to >300 ka, much older than the previous estimate at 15 ka based on classical 14C dating of fossil bones, providing one more example of the limited reliability of this chronometer. With rich relics and favorable conditions for precise dating, this site is promising for further multidisciplinary studies to address issues concerning recent human evolution in China.

    Objective To analyze the results of surveillance for acute flaccid paralysis (AFP) cases in Hunan Province during the period of 2006~2010, and to maintain the polio- free status. Methods All stool specimens from AFP cases from 2006 to 2010 were isolated and identified with L20B and RD cells according to the standard metlod issued by WHO, and all polio- positive strains were sent to National Polio Laboratory for type determination. Results The indicators of the virological surveillance for AFP cases from 2006 to 2010 were reached the requirement of the Ministry of Health of the People's Republic of China. Totally 2,566 stool specimens collected from 1,291 AFP cases had been examined, the isolated rates of poliovirus (PV) and non - polio enteroviruses (NPEV) were 3.43% and 12.98%, respectively. Among 52 positive specimens, 45 were identified as vaccine- variant polioviruses, others were identified as vaccine- related polioviruses, and no polio-wild virus was found. The enteroviruses were isolated all over the years, especially from May to July. The positive cases of poliovirus (PV) covered all the areas of Hunan Province except Xiangtan and Zhangjiajie. There were statistically significant differences in NPEV infection rates among different age groups of AFP cases (P<0.01). The isolated rate of PV was descended when the age was increased. There were statistically significant differences in the isolated rate of PV among the AFP cases with different immunization histories (P < 0.01). The more the OPV immunizations the lower the residual paralysis occurred for AFP cases with PV infection. Conclusions The result of surveillance from 2006 to 2010 indicates that the implementation of polio eradication strategy in Hunan Province is effective and the polio wild virus has been successfully intervened. The target of polio- free is achieved in Hunan Province. But the virological surveillance for AFP cases should be also enhanced on the endgame of poliomyelitis free so

  2. Salt ingestion caves.

    2006-01-01

    Full Text Available Large vertebrate herbivores, when they find a salt-bearing layer of rock, say in a cliff face, can produce sizable voids where, overgenerations, they have removed and consumed salty rock. The cavities formed by this natural animal process constitute a uniqueclass of caves that can be called salt ingestion caves. Several examples of such caves are described in various publications. Anexample in Mississippi U.S.A., Rock House Cave, was visited by the authors in 2000. It seems to have been formed by deer orbison. Perhaps the most spectacular example is Kitum Cave in Kenya. This cave has been excavated to a length over 100 metersby elephants. An ancient example is La Cueva del Milodon in Chile, which is reported to have been excavated by the now extinctmilodon, a giant ground sloth. Still other possible examples can be cited. This class of caves deserves a careful definition. First, thecavity in rock should meet the size and other conventions of the locally accepted definition of a cave. Of course this requirement differsin detail from country to country, particularly in the matter of size. The intent is to respect the local conventions. The characteristicthat human entry is possible is judged to be a crucial property of any recognized cave definition. Second, the cavity should besignificantly the result of vertebrate animal consumption of salt-bearing rock. The defining process is that rock removed to form thecave is carried away in the digestive track of an animal. While sodium salts are expected to be the norm, other salts for which thereis animal hunger are acceptable. Also some other speleogenesis process, such as solution, should not be excluded as long as it issecondary in formation of a cave in question.

    In this study, we focused on measuring levels of nurse burnout and job dissatisfaction in the daily practice of nurses in Hunan province, China, analyzed factors related to nurse burnout and job dissatisfaction, and explored the relationship between them. Previous studies have shown a high level of burnout and job dissatisfaction among nurses worldwide. A cross-sectional survey of 1100 nurses was conducted. The nurses worked at 20 hospitals in 11 cities and counties throughout China's Hunan province. Nurse burnout was measured by the Maslach Burnout Inventory. Nurse-rated job dissatisfaction was described using a four point scale, and work environment was measured using the Nursing Work Index - Practice Environment Scale. The results showed that nurses had high burnout scores and were dissatisfied with their jobs. Staffing, work environment, and work hours were all significantly associated with nurse burnout and job dissatisfaction. Adequate staffing, improved work environment, and reasonable work hours are related to decreasing nurse burnout and job dissatisfaction.

    The connotation of food security includes total safety, structural safety, quality security, price security, ecological security and industrial security. Learning from the experience of foreign grain cooperatives to ensure food security, development of the food professional cooperatives in China helps to promote marketization, scalization, intensification and modernization of food production, which is the fundamental way to solve the issue of food security in China. The development of food professional cooperatives in Hunan, which is China's major grain producing areas, is faced with small -scale, poor land transfer, short chain, weakness of water conservancy infrastructure and financing difficulties, and needs to take appropriate measures to resolve and play a positive role in ensuring national food security of food professional cooperatives.%粮食安全的内涵包括总量安全、结构安全、质量安全、价格安全、生态安全和产业安全。借鉴国外粮食合作社保障粮食安全的经验,我国发展粮食专业合作社有利于促进粮食生产的市场化、规模化、集约化和现代化,是解决我国粮食安全问题的根本出路。湖南作为我国粮食主产区,其粮食专业合作社的发展面临着规模小、土地流转不畅、产业链短、农田水利基础设施薄弱及融资难等问题,需要采取相应措施加以解决以发挥粮食专业合作社在确保国家粮食安全中的积极作用。

    The aim of this study was to determine the energy expenditure of a group of cavers of both genders and different ages and experience during a 10 hour subterranean exploration, using portable metabolimeters. The impact of caving activity on body composition and hydration were also assessed through bioelectrical impedance, and nutritional habits of cavers surveyed. During cave activity, measured total energy expenditure (TEE) was in the range 225-287 kcal/h for women-men (MET = 4.1), respectively; subjects had an energy intake from food in the range 1000-1200 kcal, thus inadequate to restore lost calories. Bayesian statistical analysis estimated the effect of predictive variables on TEE, revealing that experienced subjects had a 5% lower TEE than the less skilled ones and that women required a comparatively larger energy expenditure than men to perform the same task. BIVA (bioelectrical impedance vector analysis) showed that subjects were within the range of normal hydration before and after cave activity, but bioelectrical changes indicated a reduction of extracellular water in men, which might result in hypo-osmolal dehydration in the case of prolonged underground exercise. All these facts should be considered when planning cave explorations, preparing training programs for subjects practising caving, and optimizing a diet for cavers. Further, information gathered through this study could be of value to reduce accidents in caves related to increase in fatigue.

    Large amounts of tailings were produced during mining in the Xiangxi Gold Mine, Hunan. The interaction of tailing with water has caused the release and migration of heavy metals in tailings and the contamination to surfacial environments of water bodies,soils and vegetables. The main contaminating elements are Au, Sb, As, Hg and W, and this is consistent with the elemental enrichment features of tailings. The water migration coefficients of heavy metals in tailings tend to decreased in the order: Au>Cd>W>Sb>Pb>As>Zn>Cu, similar to the pollution severity in soils and vegetable, indicating that the pollution is controlled by tailings-water interaction. The biological absorption coefficients of heavy metals vary in a complex manner and are larger with Au, Sb, Cd, and Zn. The metallic element concentrations in plants are mainly controlled by their concentrations in soils and plants, and absorption coefficients.%湘西金矿在生产过程中产生了大量的尾矿。该区尾矿-水相互作用强烈,并引起了尾矿中重金属元素的释放、迁移和对水体、土壤、蔬菜等表生环境的重金属污染。污染程度较大的元素均为Au、Sb、As、Cd、Hg、W等,与尾矿中元素的富集特征相一致。尾矿中重金属元素的水迁移能力由大至小顺序为Au、Cd、W、Sb、Pb、As、Zn、Cu。元素的生物吸收系数由大至小顺序为Cd、Au、Zn、Hg、Sb、Cu、Pb、As、W。植物中金属元素浓度主要受土壤中的浓度、植物种类和吸收能力的影响。

    农村劳动力非农转移是我国城乡发展过程中的普遍现象,也是实现工业化、城镇化和农业现代化协调发展的重要前提。基于河北、湖南、福建3省林区41个村、290户林农的实地调研数据,利用Logistic回归模型对影响林区劳动力外出务工的因素进行了比较分析。结果表明:研究区劳动力外出务工的农户占样本的比重超过60%,林业劳动力非农转移已成为常态。河北保定林农的流动受个人禀赋影响较大,对家庭因素不敏感;湖南邵阳、福建三明林农的流动多受家庭因素影响;农林业经营情况对3个地区林农的流动影响均较大。针对林区劳动力非农转移的现实状况,认为发展地方特色产业、用科技实现规模效应及培育社会支持体系等是实现林区农村剩余劳动力合理流动、提升人力资源使用效率的重要途径。%Rural farming labor being transferred to non-farming one is not only a common phenomenon in the development of urban and rural areas in China, but also an important prerequisite for the coordinated development of industrialization, urbanization, and agricultural modernization. The article uses the sample data of 290 households from 41 villages in Hebei, Hunan and Fujian provinces, and makes comparative analyses on the factors affecting the migration of forestry labor through the Logistic regression model. The result shows that migrant labor households account for 60% of the sample. Personal endowments have greater influence on the migration than family factors in Baoding city of Hebei, while migrations in Shaoyang city of Hunan and Sanming city of Fujian are mainly affected by family factors. Besides, the operation of agroforestry has widespread impacts on the migration of forest labor in these three cities. According to actual situations in forest regions, it is suggested that developing industries with local characteristics, using science and technology

  9. Hydrodynamic aspect of caves

    2008-01-01

    Full Text Available From a hydrological point of view, active caves are a series of connected conduits which drain water through an aquifer. Water tends to choose the easiest way through the system but different geological and morphological barriers act as flow restrictions. The number and characteristics of restrictions depends on the particular speleogenetic environment, which is a function of geological, geomorphological, climatological and hydrological settings. Such a variety and heterogeneity of underground systems has presented a challenge for human understanding for many centuries. Access to many underground passages, theoretical knowledge and recent methods (modeling, water pressure-resistant dataloggers, precise sensors etc. give us the opportunity to get better insight into the hydrodynamic aspect of caves. In our work we tried to approach underground hydrodynamics from both theoretical and practical points of view. We present some theoretical background of open surface and pressurized flow in underground rivers and present results of some possible scenarios. Moreover, two case studies from the Ljubljanica river basin are presented in more detail: the cave system between Planinsko polje and Ljubljansko barje, and the cave system between Bloško polje and Cerkniško polje. The approach and methodology in each case is somewhat different, as the aims were different at the beginning of exploration. However, they both deal with temporal and spatial hydrodynamics of underground waters. In the case of Bloško polje-Cerkniško polje system we also explain the feedback loop between hydrodynamics and Holocene speleogenesis.

    2014-09-01

    Euscorpiops dakrong sp. n., belonging to the family Euscorpiidae Laurie, is described on the basis of one male and one female collected in the Dakrong Nature Reserve cave system, Dakrong District, Quang Tri Province, Vietnam. The new species presents most features exhibited by scorpions of the genus Euscorpiops, but it is characterized by a slender body and elongated pedipalps. This new scorpion taxon represents the second species of Scorpiopinae discovered in a cave system and may be yet another endemic element in the fauna of Vietnam. Some taxonomic propositions on the generic position of Scorpiops oligotrichus Fage, 1933 are also suggested.

    Previous studies of non-tax revenue were generally based on the macro-analysis and the conlusions were al-so different.By using the panel data of ten counties of Hunan Province between 2007 and 2012,this paper starts from the internal structure of non-tax revenue,uses the fixed effect model and conducts an empirical analysis of the relationship be-tween non-tax revenue and economic growth.The results indicate that two types of non-tax revenue have a promoting effect on economic growth,including the income from use of state-owned resources (assets)and penalty receipts and revenue from government-controlled funds.Among them,the income from use of state-owned resources (assets)makes the greatest contribution to economic growth.However,the charge of administative and insitutional units has no significant effect on e-conomic growth.%以往对非税收入与经济增长关系的研究大多是基于总量分析,且结论也存在诸多分歧。本文利用湖南省2007~2012年10个县市的面板数据,从非税收入内部结构出发,运用固定效应模型对非税收入与经济增长间的关系进行实证分析。结果表明:国有资源资产类使用收入、罚没收入和政府基金类收入总体上对经济增长具有促进作用,且以国有资源类收入对经济增长的贡献程度最大,而行政事业性收入对经济增长则无显著影响。

    领导干部的社会性别意识在很大程度上决定了他们能否真正贯彻落实“社会性别主流化”的要求。文章基于湖南省领导干部的调查资料,从性别问题的认知、性别关系的评价、性别观念与态度、性别意识的践行四个方面分析了当前领导干部社会性别意识的现状。研究发现,领导干部对男女平等基本国策、社会性别基本概念的认知还有待进一步提高;领导干部的一些性别观念还有待进一步转变;性别意识的践行还存在着诸多缺损的地方。因此,必须通过各种途径,进一步提高领导干部的社会性别意识。%Gender consciousness of leading cadres largely determines whether they can really implement“gender mainstreaming”requirements. Based on the survey data of leading cadres in Hunan province, this thesis analyses the current status of gender consciousness of leading cadres from four aspects:gender cognition, evaluation of gender relationship,gender concepts and attitudes,and practice of gender consciousness. The study shows that leading cadres need to further improve their cognition of“the basic national policy of gender equality”and some basic concepts of social gender;to change some gender consciousness;practice of gender consciousness still exists many defects. Therefore,it’s necessary to further improve the social gender consciousness of leaders through a variety of ways.

    The Middle Permian Chihsian Formation in Sangzhi area in western Hunan Province shows remarkable cyclicity, where organic matter cycles also occurred. The study of origin of organic matter accumulation in the Chihsian Formation helps understand the role of sea level fluctuation on the formation of organic-carbon-rich sediments. Using a cycle as the study interval, based on the study of pyrite morphology and geochemical parameters, such as TOC, δ34S, DOP and trace elements, we find out that the variation of ocean surface water primary productivity parameters, such as Ba, Ni, Cu and Zn, are consistent with TOC contents, suggesting organic matter accumulation was controlled by primary productivity. The redox condition in bottom water is related to primary productivity. The ultimate origin for the organic matter accumulation should be the high-frequency sea level fluctuatioa Rapid sea level rising brought rich nutrients, flourishing surface water biologic productivity. The decomposition of organic matter from dead body demanded more oxygen concentration, resulting in dysoxic-anoxic environment in bottom water.%湖南西部桑植地区中二叠统栖霞组地层旋回性明显,有机质也呈周期性变化.研究其有机质聚集堆积控制因素将有助于理解海平面变化在富有机碳沉积物形成过程中的作用.选择其中一个旋回作为研究目的层段,通过黄铁矿形态以及地球化学参数有机碳TOC、硫同位素、DOP以及微量元素的研究发现,初级生产力参数Ba、Ni、Cu和Zn的变化与TOC含量的变化一致,有机质聚集堆积主要受海洋表层初级生产力的控制,底部水体氧化还原条件与初级生产力有关.有机质的堆积最终归因于高频相对海平面变化,海平面快速上升带来丰富的营养物质,提高海洋表层生物生产力,海底有机质的分解消耗大量氧气,氧需求量的增加形成底部水体贫氧厌氧环境.

    This paper ifrst analyses the problems that a mining town in Hunan province faces in its effort to promote sustainable development. The main problems include the following: the resources are on the verge of depletion; the ecological environment is damaged heavily; the social burden is heavy, and the complex geological mining relations and the compensatory of the beneift results in crisis for economic development. And then this paper points out that in our efforts to promote the transformation of mining town and its sustainable development, the two aspects that we must be taken into account: on the one hand, we desperately need both strong support of national macro-policy, and the policies concerning financial support, industrial support, and environmental protection. On the other hand, we must rely more on the functions that the local government has played, reform the management models that lay emphasis on the management and ignore the service. At the same time, we should make our efforts to break with the thought of reliance on others, attach great importance to the public power, and straighten out political and business relationships.%以矿业城镇湖南S镇为例,其可持续发展面临着资源濒临枯竭、生态环境破坏严重、社会负担沉重、地矿关系复杂和利益外流致经济发展危机重重等困境。矿业城镇的转型与可持续发展一方面迫切需要国家宏观政策的大力支持,需要资金扶持、产业扶持和环境保护等方面的政策;另一方面更离不开地方政府“内化起跳”功能的爆发,需要改革“重管理、轻服务”的管理模式,破除依赖思想,重视公众力量,理顺政企关系。

    The Xitian, Hunan Province tungsten-tin polymetallic deposit is one of the newly-discovered ones during the new round exploration in the Nanling range,which possesses a great potential of W+Sn resources. Its tungsten-tin ore bodies occur in the contact zones between complex granite and carbonaceous rock and interior of rock bodies. In addition to dominant mineralization of skarn, altered rock in fractures zone and greisen-quartz vein types also characterize the deposit, respectively. In this work, fluid inclusions Rb-Sr dating and zircon SHRIMP U-Pb dating were conducted to constrain the a- ges of the tungsten-tin greisen-quartz vein and its host granite in Xitian. The Rb-Sr isochron result shows greisen mineralization occurred at 153 + 12Ma (MSWD = 0.80) , and zircon SHRIMP U-Pb dating indicates that host granite was formed at 147.0+3.5 Ma( M SWD =-0.23 ). Both are consistent in the error range. This work further confirms that the Xitian tungsten-tin polymetallic deposit was formed primarily during the early Yanshanian epoch ( Jurassic -Cretaceous) as suggested by previous studies.%具超大型规模远景的湖南锡田钨锡多金属矿床是1999年开始的新一轮国土资源大调查的重大发现之一。矿床产于锡田复式花岗岩体与碳酸盐岩接触带及岩体内部。矿床类型主要为矽卡岩型,其次为破碎带蚀变岩型和云英岩一石英脉型。采用石英流体包裹体Rb—Sr法和锆石SHRIMPU—Pb法分别获得:云英岩一石英脉型钨锡矿形成年龄为153+12Ma(MSWD=0.80),其赋矿花岗岩形成年龄为147±3Ma(MSWD:0.90),加权平均年龄为147.0±3,5Ma(MSWD=0.23),两者在误差范围内一致;并进一步证实,锡田钨锡多金属矿的主成矿期是燕山早期。

    A series of 16 patients with meningiomas of Meckel's cave is reported. Trigeminal neuralgia, typical or atypical, was the initial symptom in 10 patients (62.5%). At admission, trigeminal signs and symptoms were present in 15 patients (93.7%); in 7 patients (43.7%), trigeminal dysfunction was combined with the impairment of other cranial nerves. On retrospective analysis, these patients fall into two clinical groups that differ also in prognosis. Group 1 comprises eight patients with trigeminal signs and symptoms only. These patients had small meningiomas strictly affecting Meckel's cave. Total removal of the tumor was achieved in seven of eight patients, without adjunctive postoperative neurological deficits. In this group, there were no tumor recurrences. Group 2 comprises the other eight patients in whom trigeminal dysfunction was combined with impairment of other cranial nerves. These patients had large tumors arising from Meckel's cave and secondarily invading the cavernous sinus (five patients) or extending into the posterior fossa (two patients) or largely growing into the middle fossa (one patient). Total removal was achieved in only one patient, and a worsening of the preoperative neurological status was observed in four patients; there were three cases of tumor progression. A subtemporal intradural approach (used in the past in every case) is still used for the small tumors of Group 1 with good results. Since 1985, for tumors involving the cavernous sinus, we have employed a frontotemporal craniotomy with extradural clinoidectomy and superior and lateral approach to the cavernous sinus. When the tumor extends toward the posterior fossa, we use a combined temporosuboccipital-transpetrosal approach.(ABSTRACT TRUNCATED AT 250 WORDS)

    四川乐山麻浩一号崖墓因其门楣上方雕刻的一尊早期佛像而著名于世,但是却很少有人注意到与其共存的其它墓内画像石刻所形成的墓内空间及其文化内涵.随着秦、汉以来巴蜀文化逐渐融入到中华文化体系,一方面,以此墓巾的画像石刻为例,可以观察到以中原汉文化为中心的主体文化的强烈影响,另一方面,也可以发现处在这一中心边缘地带的西南地区在接受主体汉文化影响的同时,也吸纳了来自更为边远地区(如中亚与南亚)的诸多史化因素,早期佛像在此墓中的出现并非偶然,而是有其更为宽广的文化背景.%The cave reliefs of Mahao in Leshan City,Sichuan Province,have been world-famous for containing an early Buddhist statue.Yet,little attention has been paid to the co-existent stone reliefs sharing the tomb cave and the cultural significance thereof.Through the Qin and Han dynasties (221 BC-220 AD),the ancient Ba and Shu civilizations in what is Sichuan today gradually merged into the Chinese civilization,of which the Han civilization is the main body,on the one hand,the Han civilization exerted a strong influence on its south-western counterparts,as is revealed by the stone reliefs in the tomb cave;on the other hand,the south-western region was apparently assimilated into the Chinese civilization while concurrently absorbing elements of even farther civilizations (e.g.,those in Central and South Asia).The early image of Buddha appeared against a wide cultural background.

    The Xianrenyan pluton is located in the south of Shuikoushan ore field, Hunan Province. There develops Au, Cu, Mo and Zn mineralization in inner and outer contact zones of the pluton, which shows the colse relationship between the pluton and the metallic mineralization. Zircon LA - MC - ICP -MS U - Pb age of the monzonite suggests a weighted mean age of (156. 09±0. 46) Ma (MSWD= 1. 4) which implies that the pluton was ernplaced in Early Yanshanian period. The in-situ Hf isotopic analysis reveals 176Hf/177Hf ratios in the zircon range from 0. 282 243 to 0. 282 904, and εHf(t) from —15. 55 to 7. 87 (with peak value around —10) , and the two stage Hf model ages(TDM2) from 703 Ma to 2 188 Ma (with peak value around 1 800 Ma), which indicates that parental magma of the pluton was derived from the mixed sources of the lower crust and mantle. Based on the geochemistry of the rocks, it can be concluded that the monzonite was mainly resulted from remelting of the Mesoproterozoic basement rocks and formed in Middle and Late Jurassic when the crust was in an extension-thinning geodynamic setting. In addition, the authors compare and analyze the lithogeochemical characteristics of the Xianrenyan pluton and the Shuikoushan stock. The fact that the Xianrenyan pluton has a weaker differentiation than the Shuikoushan pluton gives the reason for its unfavorable gold mineralization.%仙人岩岩体位于湖南水口山矿田的南部.岩体内外接触带上均见有不同程度的金、铜、钼、锌等矿化,反映出岩体与成矿存在着内在联系.二长岩中锆石的LA-MC-ICP-MS年代学研究表明,其U-Pb加权平均年龄值为(156.09±0.46)Ma(MSWD=1.4),显示为燕山早期侵位.锆石Lu-Hf同位素原位分析结果表明,176 Hf/177 Hf值为0.282 243~0.282 904,εHf (t)值为-15.55~7.87,峰值在-10左右,Hf同位素二阶段模式年龄(TDM2)为703~2 188 Ma,峰值在1 800 Ma左右,指示岩浆为壳幔混合来源.结合岩体的地球化学特征,认

    Applying the exploratory and confirmatory quantitative research methods, this article measured and analyzed the spatio-temporal evolution characteristics and influence on poverty of farmers’income diversity in Wuling Mountain Area of Hunan Province during the period of 2000 to 2012. The results showed that, first-ly, the diversity degree was low and followed the“U”shape trace, and the diversity gaps between different counties were narrowing gradually. Secondly, the counties which had the similar degrees of farmers’income diversity were clustered in a few years while scattered randomly in most of other years. Thirdly, the farmers who lived in the subareas of Loushao, Zhangjiajie had more diverse sources of income than those who lived in subareas of Huaihua and Xiangxi, and the farmers who lived in Huaihua subarea had the lowest income diversi-ty degrees and those who lived in Xiangxi subarea experienced the fastest increase of income diversity, general-ly, more and more counties in the subareas of Loushao and Xiangxi had high diversity of farmers’income sources. Fourthly, during the period of 2000 to 2012, the local spatial patterns of HH(High-High) and LH (Low-High) had moved dramatically from counties to counties, while the other patterns of HL and LL were sta-ble relatively and stayed in Huaihua subarea in most of years, and the counties which belong to Xiangxi subar-ea changed their local spatial patterns more frequently. Lastly, the diversity of income had obviously and signif-icantly influence on increasing farmers’income and reducing poverty.%应用探索性和验证性定量分析方法,测度并探讨了2000~2012年间湖南武陵山片区农民收入多样性的时空演变特征及其对贫困的影响。研究发现,湖南武陵山片区农民收入的多样性程度不高且呈现“先降后升”的趋势,不同县市区间农民收入多样性程度差距不断缩小;多样性程度相似县市区在少数年份呈现出空间集

    Full Text Available Euphrates and Tigris rivers which are born from high and snowy mountains of Eastern and Anatolia and give life to a rid regions had a vital importance for early agricultural communities. Mesopotamian civilizations advanced between these two rivers in later centuries and lots of settlements had been established near Euphrates and Tigris. One of the historical settlements is Deraser (Arık village which is in the district of today’s Batman city called Gercüş. A lot of historical remains exist there. Deraser which is about 20 kilometers away from Gercüş and constituted on a place near Tigris. There mains of various buildings, rock-cut tomb sand prehistoric pictures drawn on the walls of caves exist in Deraser (Arık village situated at the bank of Tigris river. The prehistoric painting drawn on the rocks exist in many places of Anatolia, but the paintings drawn by the technical of fresco with red and black paints rarely exist. Therefore, in Deraser, the exploration of red and black colored pictures made by soil or root paint called Berha Nivisandi (The Written Cave is a significant event. There are depictions of animals, wild animal struggles and both men and women festival scenes at cave paintings here. These cave paintings are thematically similar to prehistorical cave paintings found in many parts of the world and they have a unique style in terms of drawing technique. In our study, we will deal with the paintings compiled from the caves in the region of Deraser (The High Church which are not noticed by there searchers working there and we will mention to there search results related to these pictures.

Methods A questionnaire survey was conducted among 4248 residents, aged over 15, by a simple cluster random sampling method in Changsha, Hunan, Wulipai street North Station community. All the respondents filled out an unified epidemiological survey questionnaire. All of the respondents received examination for lung function. Those respondents showed FEV1/FVC <70% were further examined by ECG,X ray inspection for differential diagnosis. The data of epidemiological survey was analyzed by multivariate logistic regression method. Results The response rate was 92%. The total prevalence of COPD was 4. 81%.The prevalence of COPD in the males was 6. 6%, and 3. 0% in the females. The prevalence of COPD in the males was significantly higher than that in the females (x2 = 29. 915, P < 0. 01). The prevalence increased with age increasing (P <0. 01). The more the education was, the lower the prevalence of COPD was. Risk factors analyzed with non-conditional logistic were as follow. The odd ratio (OR) for COPD in the age was 1.92(P <0. 01) and the odd ratio (OR) for COPD in the sex was 1.81 (P <0. 01). The weak lighting in house increased the risk with the OR of 4. 25(P <0. 01) and pet feeding further increased the risk with the OR of 12.08(P <0. 01). The odd ratio (OR) for COPD in the smokers was 1.74(P <0. 01) and the prevalence of COPD was related with smoking intensity (branch years of cigarette). Smoking intensity above 500 increased the risk of COPD. The passive smoking increased the risk with the OR of 16. 39(P <0. 01). The odd ratio (OR) for COPD in the paternal family history with chronic pulmonary disease was 2. 13(P <0. 01) and 2. 11 (P < 0. 01) in the maternal family history. The odd ratio (OR)for COPD in the education degree was 0. 52(P < 0. 01). Conclusions The prevalence of COPD was high in Changsha city, which

    Quarries, caves and mines often contain fossils. During the '30s in Rome, the urban expansion needs for building materials such as gravel, sand and clay were extracted from quarries that surrounded the city. One of these quarries in particular, in the area of Saccopastore (Nomentana area 3 km from the University Sapienza Roma) returned an ancient human fossil skull belonging to a Neanderthal (most likely a female) who lived in Latium about 120,000 years ago. Detailed studies of this fossil were carried out by Sergio Sergi, the son of the founder of the Museum of Anthropology in Rome, Giuseppe Sergi. The museum was founded in 1884 and was later transferred to the University City (1934) where it is still located. Professor Maria Luana Belli, a science teacher in the Liceo Scientifico "G. Keplero" is a volunteer and collaborator with the Museum "G. Sergi", and she and her students retrace the places of the discovery on the trail of the Neanderthals, for understanding the evolution of the territory in a perspective of interdisciplinary teaching.

    The CAVE, a walk-in virtual reality environment typically consisting of 4-6 3 m-by-3 m sides of a room made of rear-projected screens, was first conceived and built in 1991. In the nearly two decades since its conception, the supporting technology has improved so that current CAVEs are much brighter, at much higher resolution, and have dramatically improved graphics performance. However, rear-projection-based CAVEs typically must be housed in a 10 m-by-10 m-by-10 m room (allowing space behind the screen walls for the projectors), which limits their deployment to large spaces. The CAVE of the future will be made of tessellated panel displays, eliminating the projection distance, but the implementation of such displays is challenging. Early multi-tile, panel-based, virtual-reality displays have been designed, prototyped, and built for the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia by researchers at the University of California, San Diego, and the University of Illinois at Chicago. New means of image generation and control are considered key contributions to the future viability of the CAVE as a virtual-reality device.

    Under administrative intervention, land circulation in reservoir immigration resettlements has violated related laws. Examining factors affecting residents' willingness to transfer their land in reservoir migration resettlements is meaningful to promote the land circulation in resettlement areas from a passive mode to a relatively active way. Compared to the general land circulation in rural areas, land circulation in reservoir migration resettlements show unique characteristics in many aspects, such as circulation aim, circulation significance, and government involvement. In this study, 318 questionnaires were obtained, coveting 4 reservoir immigration resettlements within Sichuan, Hunan, and Hubei provinces. The design of the questionnaire took willingness as a dependent variable but other 13 factors as independent variables, e.g., gender, age, occupational type, distance from resettlements to provincial capital, household size, and labor force. By establishing a logistic model, the authors performed an empirical study on the willingness to land circulation of local residents in reservoir resettlements. Conclusions were drawn as follows. 1) With increasing years of farmers' education, they are more inclined to transfer its land. The possible reason is that for migrant workers, the higher level of their education, the more access to work opportunities. Once these people have relatively more stable non-agricultural income, land is no longer its primary living guarantee and thus they are more willing to transfer its land to gain certain compensation. 2) The number of household labor force can result in an opposite effect on land transfer, i.e., the more labor force, the more farmers reluctant to transfer its land. 3) The greater proportion of the agricultural income to the household income, the greater reliance on agriculture farmers, and thus more reluctant to transfer its land. 4) Household size and the number of agricultural population do not accurately reflect

    Objective To explore the correlation of the androgen-related CYP17 gene polymorphism and acne cystica of Han people in Hunan province. Methods Cases studied included patients with acne vulgarisms and acne cystic and healthy people. The polymorphism was investigated by PCR using DNA from peripheral blood lymphocytes. The transition (T→C) in the risk allele (A2) produced a new recognition site for the restriction endonuclease MspA1 I. Three genotypes of androgen-related CYP17 genes (A1A1 ,A1A2,A2A2) were determined and confirmed by sequencing. Results The frequency of the A1A2 gene was not significantly different (x2=2.965,P = 0.085,OR=0.590,95% CI 0.323~1.078;x2=0.11,P = 0.74,OR=0.904,95% CI 0.498~1.641 )either from patients with acne vulgarisms and acne cystic or patients with acne vulgarisms and healthy controls. The frequency of the A1A2 gene was significantly different(x2=3.893,P = 0.048,OR=1.875,95% CI 1.001~3.510)between patients with acne cystic and healthy subjects. The frequency of the A2A2 gene was not significantly different(x2=0.015,P = 0.901,OR=0.958, 95% CI 0.490~1.875)between patients with acne vulgarisms and the healthy subjects.

    In order to explore the eco-efficiency of agro-ecosystem around the Dongting Lake region of Hunan Province, and to reveal the interrelationships among the human, natural resources, and environment in the ecosystem, this paper analyzed the emergy structure, func-tion , and efficiency of the agro-ecosystem, based on the emergy input-output data in 2009 and by using the emergy method of HT Odum. In the study period, this system was comparatively well developed in economy, and had a higher degree of mechanization and modernization. The fertiliz-er emergy and agricultural mechanical emergy accounted for 47. 13% and 10. 62% of the total, respectively, and the emergy density was 8.77×1011sej·hm-2 ·a-1. The system emergy output was unbalanced, planting emergy output was dominant, while forestry and fishery emergy output was comparatively low. The monetary value of per capita emergy output was 31873. 56 yuan, far greater than the per capita gross output value of regional economy in this system (24761. 14 yuan) , which indicated that the product pricing (especially the planting product pricing) of this system was evidently on the low side, and the value of natural resources and environment was not well reflected by the market. The environmental loading ratio was 1. 74, sustainable development index was 1.40, and population bearing capacity was 4. 91×105 (the agricultural population in this region was 3. 15·106) , showing that the system was full of vitality and development poten-tial , the pressure from natural resources and environment was not so high, but the system was un-der too much employment pressure and the population bearing capacity was overloading. In sum, to further reduce the price scissors between industrial and agricultural products, to keep on pro-tecting the market price of planting products, to adjust the agriculture industrial structure and product structure, and to transfer the surplus labor force would be the essential orientation of agri

    2009年7月对施秉屯上洞内的动物进行了调查,共获动物标本454号,隶属3门9纲16目19科20种(或类群)。该洞内的动物群由3个动物群落组成。经数理统计分析,群落多样性、均匀性、优势度和群落间相似性指数最高的分别是黑暗带群落(1.5545)、有光带群落(0.7790)、弱光带群落(0.5057)以及有光带群落和黑暗带群落(0.6249)。通过对群落多样性与部分环境因子的相关性分析,结果显示物种数(S)与湿度(H)和温度(AT)分别呈极显著的正相关和极显著的负相关(双尾显著性检验≤0.01);群落优势度(%In July 2009, this paper studied on animals in Tunshang cave of Shibing County, Guizhou Province. The collected samples were 454, belonging to 3 phyla, 9 classes, 16 orders, 19 families and 20 groups. There are 3 animal communities in this cave. According to mathematical and statistical analysis, the communities containing the highest indexes of diversity, evenness, dominance and similarity were the dark belt community ( 1. 554 5 ) , the light belt community (0. 779 0) , the reflection light belt community (0. 505 7) and the light belt community and dark belt community (0. 624 9 ) respec- tively. The results of correlation analysis between community diversity and environmental factors showed that the humidity (H)had the significantly positive correlation with number of species (S), and the air temperature (AT) had the significantly negative correlation with number of species (S), whose 2-tailed significant test is at the ≤0. 01 level. Moreover, the content of Mg in soil had the significantly positive correlation with the richness of species( C), whose 2-tailed significant test is wat the ≤0. 05 level. So these results indicated that humidity (H), air temperature (AT) and Mg were the important factors influencing change of animal community diversity in

    We used the 2005 and 2006 national surveillance data to elucidate some of the risk factors for treatment default and death among tuberculosis (TB) patients in Hunan, China. Risk of default was higher in males (odds ratio (OR) 1.25; 95% confidence interval (CI) 1.08, 1.44); lowest in patients aged 15-24 y (OR 0.60; 95% CI 0.49, 0.75), and generally increased with increasing age; lower in patients living in cities with per capita gross domestic product (GDP) of less than 1000 US$ (OR 0.60, 95% CI 0.49, 0.72), and increased with increasing per capita GDP of city of residence; and higher in patients with previously treated smear-positive pulmonary TB (diagnostic category II according to the World Health Organization definition; OR 1.99; 95% CI 1.22, 3.23). Risk of death was lowest in patients aged 15-24 y (OR 0.07; 95% CI 0.05, 0.10), and increased with increasing age; lower in new cases (OR 0.50; 95% CI 0.33, 0.76); and highest in patients who treated themselves (OR 3.47; 95% CI 1.27, 9.46). We conclude that male TB patients, elderly TB patients, patients resident in cities with higher per capita GDP, and patients receiving category II treatment need special attention to reduce TB treatment default in the province. Furthermore, elderly TB patients and patients with a long history of TB need special attention to reduce mortality. Self-treatment also needs to be discouraged to reduce mortality.

  16. Comparing flow-through and static ice cave models for Shoshone Ice Cave

    Full Text Available In this paper we suggest a new ice cave type: the “flow-through” ice cave. In a flow-through ice cave external winds blow into the cave and wet cave walls chill the incoming air to the wet-bulb temperature, thereby achieving extra cooling of the cave air. We have investigated an ice cave in Idaho, located in a lava tube that is reported to have airflow through porous wet end-walls and could therefore be a flow-through cave. We have instrumented the site and collected data for one year. In order to determine the actual ice cave type present at Shoshone, we have constructed numerical models for static and flow-through caves (dynamic is not relevant here. The models are driven with exterior measurements of air temperature, relative humidity and wind speed. The model output is interior air temperature and relative humidity. We then compare the output of both models to the measured interior air temperatures and relative humidity. While both the flow-through and static cave models are capable of preserving ice year-round (a net zero or positive ice mass balance, both models show very different cave air temperature and relative humidity output. We find the empirical data support a hybrid model of the static and flow-through models: permitting a static ice cave to have incoming air chilled to the wet-bulb temperature fits the data best for the Shoshone Ice Cave.

    Based on U/Th dates and 205 oxygen isotopic dates a record of the Asian Summer Monsoon ( ASM ) on millennial time scales was established during the Antepenultimate Glacial MIS8-MIS9 from stalagmite LM-1 in Laomu Cave from southeast of the Loess Plateau, the west of Henan Province, China. The minimum δ18O value of stalagmite LM-1 is -11.38‰, the maximum value is -6. 99‰ and the vibration amplitude reach -4. 37‰, mean -9.07‰, and showed this area was strongly affected by the Asian Monsoon system during the Antepenultimate Glacial. The S 0 record of stalagmite LM-1 is similar to that of the stalagmite LZ-15 of Linzhu Cave in Shennongjia, Hubei Province, China. The precession cycle from the two stalagmites have some correlation with the same period of summer solar radiation of north latitude 65 , which shows Henan and Hubei are controlled by the same climate system in a long time scale and solar radiation is still the major factor of climate change. At the transition of MIS8/9, the record of LM-1 shows the same trends with the decline of CO2 content from the Ice core Vostok, Antarctic. So we can infer from that the content of CO2, CH4and NO2 changing may amplify the climate fluctuation caused by the orbit driven.%通过对河南西部栾川县老母洞LM-1石笋U/Th年龄和205个氧同位素的分析,初步建立起黄土高原东南缘豫西地区倒数第三次冰期(氧同位素MIS8-MIS9阶段)千年尺度的亚洲季风演化特征.LM-1石笋δ18O记录最轻为- 11.38‰.,最重为-6.99‰,振幅达4.37‰,平均值为-9.07‰,说明LM-1石笋敏感地记录了该时期的亚洲季风气候变化历史.LM-1石笋δ18记录与湖北神农架林竹洞LZ-15石笋记录十分类似,同时两者记录的岁差旋回与同时期北纬65.N夏季太阳辐射变化曲线有一定相关性,表明河南和湖北两地在长时间尺度上都受相同的气候系统控制,并且太阳辐射是该时段气候变化的主要驱动因素.LM-1石笋记录的MIS8-M1S9

    Sensen, Christoph W

    2002-01-01

    We have established the first Java 3D-enabled CAVE (CAVE automated virtual environment). The Java application programming interface allows the complete separation of the program development from the program execution, opening new application domains for the CAVE technology. Programs can be developed on any Java-enabled computer platform, including Windows, Macintosh, and Linux workstations, and executed in the CAVE without modification. The introduction of Java, one of the major programming environments for bioinformatics, into the CAVE environment allows the rapid development applications for genome research, especially for the analysis of the spatial and temporal data that are being produced by functional genomics experiments. The CAVE technology will play a major role in the modeling of biological systems that is necessary to understand how these systems are organized and how they function.

  1. Candidate cave entrances on Mars

    Cushing, Glen E.

    2012-01-01

    This paper presents newly discovered candidate cave entrances into Martian near-surface lava tubes, volcano-tectonic fracture systems, and pit craters and describes their characteristics and exploration possibilities. These candidates are all collapse features that occur either intermittently along laterally continuous trench-like depressions or in the floors of sheer-walled atypical pit craters. As viewed from orbit, locations of most candidates are visibly consistent with known terrestrial features such as tube-fed lava flows, volcano-tectonic fractures, and pit craters, each of which forms by mechanisms that can produce caves. Although we cannot determine subsurface extents of the Martian features discussed here, some may continue unimpeded for many kilometers if terrestrial examples are indeed analogous. The features presented here were identified in images acquired by the Mars Odyssey's Thermal Emission Imaging System visible-wavelength camera, and by the Mars Reconnaissance Orbiter's Context Camera. Select candidates have since been targeted by the High-Resolution Imaging Science Experiment. Martian caves are promising potential sites for future human habitation and astrobiology investigations; understanding their characteristics is critical for long-term mission planning and for developing the necessary exploration technologies.

    Full Text Available The physical processes that establish the cave temperature are briefly discussed, showing that cave temperature is generally strictly connected with the external climate. The Global Climatic changes can then influence also the underground climate. It is shown that the mountain thermal inertia causes a delay between the two climates and then a thermal unbalance between the cave and the atmosphere. As a consequence there is a net energy flux from the atmosphere to the mountain, larger than the geothermal one, which is deposited mainly in the epidermal parts of caves.

In this paper, the application of GPR to vertical karst caves was introduced in Zhangjiajie-Huayuan Expressway of Hunan Province, and the effectiveness of the complex signal analysis was illuminated in GPR data processing. A vertical karst cave characterized by a small horizontal scale would arose an unintelligible anomaly in the GPR image, which could not be recognized easily. The authors first processed the GPR data by two-dimensional spatial filter, and then applied Hilbert transform to the data, thus obtaining the transient amplitude, transient phase and transient frequency. Finally, the authors analyzed the processed data synthetically. The results show that the spatial filter can remarkably eliminate high frequency noise and improve SNR of the signal. In addition, the accuracy of the GPR interpretation can be improved by the multi-parameter analytical method. Drilling results prove the correctness of the inversion interpretation.

    Although there are many ways to create three dimensional representations of caves using modern information technology methods, modeling of caves has been challenging for researchers for a long time. One of these promising new alternative modeling methods is using voxels. We are using geodetic measurements as an input for our voxelization project. These geodetic underground surveys recorded the azimuth, altitude and distance of corner points of cave systems relative to each other. The diameter of each cave section is estimated from separate databases originating from different surveys. We have developed a simple but efficient method (it covers more than 99.9 % of the volume of the input model on the average) to convert these vector-type datasets to voxels. We have also developed software components to make visualization of the voxel and vector models easier. Since each cornerpoint position is measured relative to another cornerpoints positions, propagation of uncertainties is an important issue in case of long caves with many separate sections. We are using Monte Carlo simulations to analyze the effect of the error of each geodetic instrument possibly involved in a survey. Cross-sections of the simulated three dimensional distributions show, that even tiny uncertainties of individual measurements can result in high variation of positions that could be reduced by distributing the closing errors if such data are available. Using the results of our simulations, we can estimate cave volume and the error of the calculated cave volume depending on the complexity of the cave.

    Underground caves bear a natural hazard due to their possible evolution into a sink hole. Mapping of all existing caves could be useful for general civil usages as natural deposits or tourism and sports. Natural caves exist globally and are typical in karst areas. We investigate the resolution power of modern gravity campaigns to systematically detect all void caves of a minimum size in a given area. Both aerogravity and terrestrial acquisitions are considered. Positioning of the gravity station is fastest with GNSS methods the performance of which is investigated. The estimates are based on a benchmark cave of which the geometry is known precisely through a laser-scan survey. The cave is the Grotta Gigante cave in NE Italy in the classic karst. The gravity acquisition is discussed, where heights have been acquired with dual-frequency geodetic GNSS receivers and Total Station. Height acquisitions with non-geodetic low-cost receivers are shown to be useful, although the error on the gravity field is larger. The cave produces a signal of -1.5 × 10-5 m/s2, with a clear elliptic geometry. We analyze feasibility of airborne gravity acquisitions for the purpose of systematically mapping void caves. It is found that observations from fixed wing aircraft cannot resolve the caves, but observations from slower and low-flying helicopters or drones do. In order to detect the presence of caves the size of the benchmark cave, systematic terrestrial acquisitions require a density of three stations on square 500 by 500 m2 tiles. The question has a large impact on civil and environmental purposes, since it will allow planning of urban development at a safe distance from subsurface caves. The survey shows that a systematic coverage of the karst would have the benefit to recover the position of all of the greater existing void caves.

    A case of a cavernous hemangioma located within Meckel's cave and involving the gasserian ganglion is described in a patient presenting with facial pain and a trigeminal nerve deficit. Although these lesions have been reported to occur in the middle fossa, this is believed to be the first case of such a vascular malformation arising solely from within Meckel's cave.

    Magnetic resonance imaging (MRI) gives an accurate analysis of Meckel's cave variability. Images were acquired in 50 patients with several sections for anatomical comparison. Using several sections, MRI is a suitable method for better analysis of the trigeminal cistern. The most frequent findings are symmetrical trigeminal cisterns. Expansion of Meckel's cave or its disappearance has pathological significance.

    Full Text Available This paper presents a denuded cave situated in the area of Podbojev laz, on the northwestern side of the Rakov Škocjan. Morphometric and morphogenetic properties of several sections of the denuded cave and its surroundings are described in detail. The denuded cave developed from an epiphreatic cave system which used to function as an outflow cave system from the Rak valley. Morphometrical analysis of the slopes show that the denuded cave was developedin stages. As the surrounding surface is not flattened, the cave roof must have been denuded gradually.

    2000-01-01

    Full Text Available The problems concerning the development of show caves are here considered by taking into account different aspects of the problem. A procedure to carry out an Environmental Impact Assessment (EIA has been established in the last decade and it is now currently applied. Such an assessment starts with a pre-operational phase to obtain sufficient information on the undisturbed status of a cave to be developed into a show cave. Successively a programme for its development is established with the scope to optimise the intervention on the cave at the condition that its basic environmental parameters are not irreversibly modified. The last phase of the assessment is focussed to assure a feedback through a monitoring network in order to detect any unforeseen difference or anomaly between the project and the effective situation achieved after the cave development. Some data on some of the most important show caves in the world are reported and a tentative evaluation of the economy in connection with the show caves business is eventually made.

  16. Minerogenesis of volcanic caves of Kenya.

    2003-01-01

    Full Text Available Kenya is one of the few countries in which karst cavities are scarce with respect to volcanic ones, which are widespread throughout the whole country. The great variability in lava composition allowed the evolution of very different cavities, some of which are amongst the largest lava tubes of the world. As normal for such a kind of cave, the hosted speleothems and cave minerals are scarce but important from the minerogenetic point of view. Anyway up to present no specific mineralogical research have been carried out therein. During the 8th International Symposium on Volcanospeleology, held in Nairobi in February 1998, some of the most important volcanic caves of Kenya have been visited and their speleothems and/or chemical deposits sampled: most of them were related to thick guano deposits once present inside these cavities. Speleothems mainly consisted of opal or gypsum, while the deposits related to guano often resulted in a mixture of sulphates and phosphates. The analyses confirmed the great variability in the minerogenetic mechanisms active inside the volcanic caves, which consequently allow the evolution of several different minerals even if the total amount of chemical deposit is scarce. Among the observed minerals kogarkoite, phillipsite and hydroxyapophyllite, must be cited because they are new cave minerals not only for the lava tubes of Kenya, but also for the world cave environment. The achieved results are compared with the available random data from previous literature in order to allow an updated overview on the secondary cave minerals of Kenya.

  19. Does the Cave Environment Reduce Functional Diversity?

    Science.gov (United States)

    Fernandes, Camile Sorbo; Batalha, Marco Antonio; Bichuette, Maria Elina

    2016-01-01

    Caves are not colonised by all taxa present in the surface species pool, due to absence of light and the tendency to food limitation when compared to surface communities. Under strong species sorting during colonisation and later by the restrictive environmental filter, traits that are not adaptive in subterranean habitats may be filtered out. We tested whether cave communities were assembled by the restrictive regime propitiated by permanent darkness or by competitive exclusion due to resource scarcity. When compared to surface communities, the restrictive subterranean regime would lead to lower functional diversity and phenotypic clustering inside the caves, and the opposite should be expected in the case of competitive exclusion. Using isopods (Oniscidea) as model taxa, we measured several niche descriptors of taxa from surface and cave habitats, used a multivariate measure of functional diversity, and compared their widths. We found phenotypic overdispersion and higher functional diversity in cave taxa when compared to surface taxa. On the one hand, the dry climate outside of caves hampered the survival of several taxa and their ecological strategies, not viable under severe desiccation risk, culminating in the clustering of functional traits. In contrast, this restriction does not occur inside of caves, where isopods find favourable conditions under lower predation pressures and more amenable environmental parameters that allow occupation and subsequent diversification. Our results showed that, at least for some taxa, caves may not be such a harsh environment as previously thought. The high functional diversity we found inside caves adds an additional reason for the conservation of these sensitive environments.

    Hunan is a province with abundant cultural relics and splendid ancient culture in South China. Since the founding of New China, archaeological work has vigorously grown across this region and has continuously obtained new fruits through its three major developmental stages. Spectacular achievements have been acquired in the understanding of Palaeolithic cultural groups, the study of cultural remains at the transitional stage between the Palaeolithic and Neolithic Age, the establishment of the pedigree of Neolithic archaeological cultures and research on early Neolithic cultures, the investigation of the origin of rice agriculture and prehistoric city-sites, the revelation of remains of archaeological cultures in Shang and Zhou times and the grouping of bronzes, the discovery and study of numerous tombs from the Chu and Han periods, and the archaeology of kiln-sites and the study of ceramics. At present, archaeological work in Hunan has reached the new stage when excavations and synthetic studies are carried out mainly around important archaeological problems. With the application of new techniques and the deepening of researches, it will certainly achieve more glorious success in the new century.

    Centred around 37l indexes including natural environment, human activities, condition of society, economic situation,forest resources, forestry organizations, technology, management and administration, we have investigated 105 counties(cities,districts) in Hunan Province. Eighty three counties out of them were designated for our research objects. For each county,we selected 28 indexes which had directly bearing on our social forestry project such as natural environment, social economy, forest resources. Then through Cluster Analysis and Factor Analysis, we used a social science statistical analysis software(SPSS) to analyze the impact of natural, environmental, social, economical and forest resources' factors on community forestry activities. Based on such work, we have established a set of indexes system for Hunan provincial social forestry project' s regionaleval uation. According to the cluster analysis results and the current situation of the project implementation, Hunan provincial social forestry project could be divided into five types, the results will provide a scientific basis for Hunan provincial social forestry project' s implementation.

    High resolution CT of the parasellar region was carried out in 50 patients studied for suspected pituitary microadenoma, but who showed normal pituitary gland or microadenoma on CT. This control group of patients all showed an ellipsoid low-density area in the posterior parasellar region. Knowledge of the gross anatomy and correlation with metrizamide cisternography suggest that the low density region represents Meckel's cave, rather than just the trigeminal ganglion alone. Though there is considerable variation in the size of Meckel's cave in different patients as well as the two sides of the same patient, the rather constant ellipsoid configuration of the cave in normal subjects will aid in diagnosing small pathological lesions, thereby obviating more invasive cisternography via the transovale or lumbar route. Patients with "idiopathic" tic douloureux do not show a Meckel's cave significantly different from the control group.

    Full Text Available Lascaux Cave in France contains valuable Palaeolithic paintings. The importance of the paintings, one of the finest examples of European rock art paintings, was recognized shortly after their discovery in 1940. In the 60’s of the past century the cave received a huge number of visitors and suffered a microbial crisis due to the impact of massive tourism and the previous adaptation works carried out to facilitate visits. In 1963, the cave was closed due to the damage produced by visitors’ breath, lighting and algal growth on the paintings. In 2001, an outbreak of the fungus Fusarium solani covered the walls and sediments. Later, black stains, produced by the growth of the fungus Ochroconis lascauxensis, appeared on the walls. In 2006, the extensive black stains constituted the third major microbial crisis. In an attempt to know the dispersion of microorganisms inside the cave, aerobiological and microclimate studies were carried out in two different seasons, when a climate system for preventing condensation of water vapor on the walls was active (September 2010 or inactive (February 2010. The data showed that in September the convection currents created by the climate system evacuated the airborne microorganisms whereas in February they remained in suspension which explained the high concentrations of bacteria and fungi found in the air. This double aerobiological and microclimate study inLascauxCave can help to understand the dispersion of microorganisms and to adopt measures for a correct cave management.

    Despite the information content of genomic DNA, ancient DNA studies to date have largely been limited to amplification of mitochondrial DNA due to technical hurdles such as contamination and degradation of ancient DNAs. In this study, we describe two metagenomic libraries constructed using unamplified DNA extracted from the bones of two 40,000-year-old extinct cave bears. Analysis of {approx}1 Mb of sequence from each library showed that, despite significant microbial contamination, 5.8 percent and 1.1 percent of clones in the libraries contain cave bear inserts, yielding 26,861 bp of cave bear genome sequence. Alignment of this sequence to the dog genome, the closest sequenced genome to cave bear in terms of evolutionary distance, revealed roughly the expected ratio of cave bear exons, repeats and conserved noncoding sequences. Only 0.04 percent of all clones sequenced were derived from contamination with modern human DNA. Comparison of cave bear with orthologous sequences from several modern bear species revealed the evolutionary relationship of these lineages. Using the metagenomic approach described here, we have recovered substantial quantities of mammalian genomic sequence more than twice as old as any previously reported, establishing the feasibility of ancient DNA genomic sequencing programs.

    Yangjiaping section is located in Hupingshan Town, Shimen County, Hunan Province. The section has been intensively studied since 1980. However, The paleoclimate during the deposition of the Xieshuihe Formation remains controversial. Based on chemical analysis of sedimentary clastic rocks of the unit, the resulting CIA (the chemical index of alteration) values of the Xieshuihe Formation are similar to those of the overlying Gucheng Formation (also called the Dongshanfeng Formation). It indicates that the sedimentary rocks of the Xieshuihe Formation and Gucheng Formation underwent the similar degrees of chemical weathering before deposition. Therefore, the Xieshuihe Formation was also likely to be deposited under a cold climatic condition, which probably belongs to a part of the record of glaciations.

    Mammoth Cave is the main attraction of Mammoth Cave National Park. For several decades it has been the longest known cave in the world and currently contains 652 km in 2016 of surveyed passages. It is located in the heart of an extensive karst plateau, in which the stratal dip averages only one degree. The cave is part of a drainage basin of more than 200 km{sup 2}. The cave has been known to local inhabitants for several millennia and contains a rich trove of archaeological and historical artifacts. It contains many speleo biota including several rare and endangered species and has been designated a World Heritage Site and an International Biosphere Reserve (UNESCO). Its many passage levels and sediments contain a record of the fluvial history of most of south-eastern North America. (Author)

    The invention of pottery introduced fundamental shifts in human subsistence practices and sociosymbolic behaviors. Here, we describe the dating of the early pottery from Xianrendong Cave, Jiangxi Province, China, and the micromorphology of the stratigraphic contexts of the pottery sherds and radiocarbon samples. The radiocarbon ages of the archaeological contexts of the earliest sherds are 20,000 to 19,000 calendar years before the present, 2000 to 3000 years older than other pottery found in East Asia and elsewhere. The occupations in the cave demonstrate that pottery was produced by mobile foragers who hunted and gathered during the Late Glacial Maximum. These vessels may have served as cooking devices. The early date shows that pottery was first made and used 10 millennia or more before the emergence of agriculture.

    According to the engineering features of subgrade cave roof in karst region, the clamped beam model of subgrade cave roof in karst region was set up. Based on the catastrophe theory, the cusp catastrophe model for bearing capacity of subgrade cave roof and safe thickness of subgrade cave roof in karst region was established. The necessary instability conditions of subgrade cave roof were deduced, and then the methods to determine safe thickness of cave roofs under piles and bearing capacity of subgrade cave roof were proposed. At the same time, a practical engineering project was applied to verifying this method, which has been proved successfu1ly. At last, the major factors that affect the stability on cave roof under pile in karst region were deeply discussed and some results in quality were acquired.

    Full Text Available The Lenggong Valley, from a standpoint of natural tourism research, presents strengths, weaknesses, opportunities and challenges that can be utilized to help increase the opportunities for the local community to increase their standard of living. Asar Cave comprises one of the caves that are found in Lenggong. A series of external studies have been done on Asar Cave in order to measure its potential for natural tourism in Lenggong. The objective of this study is to discuss caves as a natural resource that has great potential in the growth of the economy of the residents of the Lenggong Valley. Marketing caves as a source of nature tourism helps the government’s achievements in National Key Result Areas, apart from being a form of environmental control as well as helping to increase awareness about environmental education, specifically those associated with caves. The research results find that SWOT analysis presents huge potential for caves to become a source of nature tourism development in Lenggong. Great potential can also be seen from a standpoint of increasing the standard of living of its residents through their involvement in the tourism sector based on local natural assets.

    With the fast development of remote sensing technology, combining forest inventory sample plot data and remotely sensed images has become a widely used method to map forest carbon density. However, the existence of mixed pixels often impedes the improvement of forest carbon density mapping, especially when low spatial resolution images such as MODIS are used. In this study, MODIS images and national forest inventory sample plot data were used to conduct the study of estimation for forest carbon density. Linear spectral mixture analysis with and without constraint, and nonlinear spectral mixture analysis were compared to derive the fractions of different land use and land cover (LULC) types. Then sequential Gaussian co-simulation algorithm with and without the fraction images from spectral mixture analyses were employed to estimate forest carbon density of Hunan Province. Results showed that 1) Linear spectral mixture analysis with constraint, leading to a mean RMSE of 0.002, more accurately estimated the fractions of LULC types than linear spectral and nonlinear spectral mixture analyses; 2) Integrating spectral mixture analysis model and sequential Gaussian co-simulation algorithm increased the estimation accuracy of forest carbon density to 81.5% from 74.1%, and decreased the RMSE to 5.18 from 7.26; and 3) The mean value of forest carbon density for the province was 30.06 t · hm(-2), ranging from 0.00 to 67.35 t · hm(-2). This implied that the spectral mixture analysis provided a great potential to increase the estimation accuracy of forest carbon density on regional and global level.

    Full Text Available This paper looks at the history of the Cave Exploration Group of East Africa with special reference to the exploration of volcanic caves. It demonstrates that the group has concentrated on two main areas, the Chyulu HiIls and Mt. Suswa, although other areas have also been studied. The Cave Exploration Group of East Africa has had to cope with various problems. The most important of which are related to the socio-economic conditions of a developing country. These problems have not prevented the group from making a valuable contribution to vulcanospeleology.

    The biggest island in South Korea is Jeju Island, which lies 80 km south of the mainland and has one shield volcano, Mt. Halla. The volcanic island and its lava tubes were added to the world heritage list by UNESCO in 2007. Among the many lava tubes on the island, a unique cave had been accidentally found in 2005 while some workers were replacing a telephone pole. Until the discovery, it had been completely isolated from the outside by naturally-built sand blocks. Yongcheon cave is a lime-decorated lava tube showing both the properties of a volcanic lava tube and a limestone cave. This cave, about 3 km in length, is acknowledged to be the best of this type in the world and includes a large clean-water lake, lava falls, and richly developed speleothems inside it. Even though there is archaeological evidence from well preserved pottery that ancient people entered this place, the preservation of artifacts was ensured by a geological change that made later entrance difficult. We have collected charcoal samples scattered around the cave and dated them using AMS. Ages were in the range of ca. 1570-1260 BP (A.D. 340-880) and this corresponds to the Ancient Three Kingdoms and the Unified Silla era in Korean history. The {sup 14}C AMS measurement results presented in this paper on wood charcoal provide precise dates which will be very useful not only to clarify the nature of human activities in this cave but also to provide reference dates when comparing other dating methods.

    2000-01-01

    Full Text Available Underground natural sources of visible light are considered. The main light producer is Cerenkov radiation emitted in air, water and rock by cosmic ray muons, that depends, in a complex way, on shape of mountain and of caves. In general the illumination increases linearly with the cavity dimensions. Other light sources are from secondary processes generated by radioactive decays in rock from minerals luminescence. The natural light fluxes in caves are in general easy to detect but are not used from underground life.

  9. Dating Petroglyphs from Fugoppe Cave, Japan

    2014-01-01

    Full Text Available For over 20 years, I have tried to establish a relative date for petroglyphs in Fugoppe Cave, Japan. Unsuspected amidst debris accumulating from about 1300 years ago, the petroglyphs were rediscovered accidentally in 1950. From an analysis of petroglyphs on fallen rocks scattered randomly on the site floor, I argue that the artworks date from ca.1900 years ago. The cave itself, formed by wave action, saw its main occupation by pottery-making people from 1700–1500 years ago; although the petroglyphs on the rock walls predated their occupation, it seems unlikely that the occupants attached any meaning to them.

    Two patients with Meckel's Cave meningiomas were initially hospitalized as a result of subarachnoid hemorrhage. Four-vessel angiography was necessary to exclude other causes of bleeding while demonstrating these lesions. Apoplectic presentation in both cases led to early diagnosis and successful surgical therapy. A review of the literature reveals subarachnoid hemorrhage to be a rarity in association with meningiomas. The two patients currently reported are believed to be the only examples on record of hemorrhagic meningiomas arising from the region of Meckel's Cave.

  11. The importance of ants in cave ecology, with new records and behavioral observations of ants in Arizona caves

    2016-09-01

    Full Text Available The importance of ants as elements in cave ecology has been mostly unrecognized. A global list of ant species recorded from caves, compiled from a review of existing literature, is presented. This paper also reviews what is currently known about ants occurring in Arizona (USA caves. The diversity and distribution represented in these records suggests ants are relatively common cave visitors (trogloxenes. A general utilization of caves by ants within both temperate and tropical latitudes may be inferred from this combined evidence. Observations of ant behavior in Arizona caves demonstrate a low level and sporadic, but persistent, use of these habitats and their contained resources by individual ant colonies. Documentation of Neivamyrmex sp. preying on cave-inhabiting arthropods is reported here for the first time. Observations of hypogeic army ants in caves suggests they may not penetrate to great vertical depth in search of prey, but can be persistent occupants in relatively shallow, horizontal sections of caves where they may prey on endemic cave animals. First cave records for ten ant species are reported from Arizona caves. These include two species of Neivamyrmex (N. nigrescens Cresson and Neivamyrmex sp.; Formicidae: Dorylinae, four myrmicines (Pheidole portalensis Wilson, Pheidole cf. porcula Wheeler, Solenopsis aurea Wheeler and Stenamma sp. Westwood, one dolichoderine (Forelius keiferi Wheeler and three formicines (Lasius arizonicus Wheeler, L. sitiens Wilson, and Camponotus sp. Mayr.

    2008-03-01

    Full Text Available The Fontana Marella cave, located in the Pre-Alps in Varese province (Lombardy, North Italy, supplied a Middle Pleistocene small mammal fauna, unique for this region.Thanks to the presence of Arvicola cf. mosbachensis and Pliomys episcopalis it is possible to date this sequence to the Early Toringian. Mostly for the predominant, presence of dominant Glis glis, Chionomys nivalis and Dinaromys bogdanovi, the faunal association is attributed to a temperate period,  but cooler and perhaps more arid that the present one. The find of Macroneomys is important because it allows to extend the geographic distribution of this rare species.

    Full Text Available The life in subterranean caves always needs a high degree of biological adaptability, due to its unusual ecosystem. The cave dwelling species usually get selected from preadapted biological traits for cave life. The cave dwelling tendencies in frog are very uncommon. Majority of reported cave frogs usually prefer cave for temporary shelter. In India, the biospeleological inventory is still in its primary stage. Till date no serious attempt has been taken to understand the cave dwelling habitat for any frog in India. Inspite of it, in India time to time various reports on natural histories of anurans reveal its cave dwelling tendencies. On the basis of personal observations and available literature in this report I have documented the occurrences and distributions of five cave dwelling frogs of India. Common biological traits from all the established cave frogs, which could be referred as preadapted for cave life, have been discussed. Further, the possible threats and IUCN status of each discussed species has been highlighted.

  14. Is radon emission in caves causing deletions in satellite DNA sequences of cave-dwelling crickets?

    Directory of Open Access Journals (Sweden)

    Giuliana Allegrucci

    Full Text Available The most stable isotope of radon, 222Rn, represents the major source of natural radioactivity in confined environments such as mines, caves and houses. In this study, we explored the possible radon-related effects on the genome of Dolichopoda cave crickets (Orthoptera, Rhaphidophoridae sampled in caves with different concentrations of radon. We analyzed specimens from ten populations belonging to two genetically closely related species, D. geniculata and D. laetitiae, and explored the possible association between the radioactivity dose and the level of genetic polymorphism in a specific family of satellite DNA (pDo500 satDNA. Radon concentration in the analyzed caves ranged from 221 to 26,000 Bq/m3. Specimens coming from caves with the highest radon concentration showed also the highest variability estimates in both species, and the increased sequence heterogeneity at pDo500 satDNA level can be explained as an effect of the mutation pressure induced by radon in cave. We discovered a specific category of nuclear DNA, the highly repetitive satellite DNA, where the effects of the exposure at high levels of radon-related ionizing radiation are detectable, suggesting that the satDNA sequences might be a valuable tool to disclose harmful effects also in other organisms exposed to high levels of radon concentration.

    Karst aquifers are productive groundwater systems, supplying approximately 25 % of the world’s drinking water. Sustainable use of this critical water supply requires information about rates of recharge to karst aquifers. The overall goal of this project is to collect long-term, high-resolution hydrologic and geochemical datasets at James Cave, Virginia, to evaluate the quantity and quality of recharge to the karst system. To achieve this goal, the cave has been instrumented for continuous (10-min interval) measurement of the (1) temperature and rate of precipitation; (2) temperature, specific conductance, and rate of epikarst dripwater; (3) temperature of the cave air; and (4) temperature, conductivity, and discharge of the cave stream. Instrumentation has also been installed to collect both composite and grab samples of precipitation, soil water, the cave stream, and dripwater for geochemical analysis. This chapter provides detailed information about the instrumentation, data processing, and data management; shows examples of collected datasets; and discusses recommendations for other researchers interested in hydrologic and geochemical monitoring of cave systems. Results from the research, briefly described here and discussed in more detail in other publications, document a strong seasonality of the start of the recharge season, the extent of the recharge season, and the geochemistry of recharge.

    There is a fairly general consensus among health physicists and radiation professionals that exposure to radon progeny is the largest and most variable contribution to the population's exposure to natural sources of radiation. However, this exposure is the subject of continuing debate concerning the validity of risk assessment and recommendations on how to act in radon-prone areas. The purpose of this contribution is to situate the radon issue in Spain in two very different settings. The first is a uranium mining industry located in Saelices el Chico (Salamanca), which is under strict control of the Spanish Nuclear Safety Council (CSN). We have measured radon concentrations in different workplaces in this mine over a five-year period. The second setting comprises four tourist caves, three of which are located in the province of Cantabria and the fourth on the Canary Island of Lanzarote. These caves are not subject to any administrative control of radiation exposure. Measured air 222Rn concentrations were used to estimate annual effective doses due to radon inhalation in the two settings, and dose values were found to be from 2 to 10 times lower in the uranium mine than in the tourist caves. These results were analysed in the context of the new European Basic Safety Standards Directive (EU-BSS, 1996).

    It's quite easy to understand formation of crystals in Nature by evaporation of the solutions that contain minerals, but many times we have realised that our pupils hardly understand that precipitation is a process mostly caused by changing parameters in a solution, like pH, temperature, etc. and not necessarily depending on evaporation. We propose a hands-on activity using the context of the Cave of the Crystals in Naica's mine, Mexico. The Crystals Cave is a wonderful place where giant crystals of selenite (gypsum) have grown feeding from a supersaturated anhydrite solution1. Miners discovered the cave filled with hot water, and drained it to explore the gallery. The cave is now a giant laboratory where scientists are looking for the keys to understand geological processes. Teaching sequence (for students 15 years old) is as follows: DISCOVERING A MARVELLOUS PLACE: We showed our pupils several images and a short video of the Cave of the Crystals and ask them about the process that may have caused the phenomenon. Whole-class discussion. PRESENTING A CHALLENGE TO OUR STUDENTS: "COULD WE CREATE A CRYSTALS CAVE IN A TEST TUBE?" EXPERIMENTING TO IMITATE NATURE: Students tried to grow crystals simulating the same conditions as those in Naica's mine. We have chosen KNO3, a salt more soluble than gypsum. We added 85 g of salt to 200 ml of water (solubility of KNO3 at 25°C is 36 g per 100 gr of water) and heated it until it is dissolved. Afterwards, we poured the solution into some test tubes and other recipients and let them cool at room temperature. And they got a beautiful crystals cave!! THINKING A LITTLE MORE: we asked pupils some questions to make them think about the process and to predict what would happen in different situations. For example: a) What would happen with crystals if we heated the tubes again? or b) What would happen if we took the remaining solution from the tubes and keep it in the fridge? PROVING A NEW HYPOTHESIS: Pupils collected the remaining

    This study reports radon concentration in the most representative caves of Mallorca, identifying those in which the recommended action level is exceeded, thus posing health risks. Two show caves (Campanet and Artà) and three non-touristic caves (Font, Drac, Vallgornera) were investigated. Data were collected at several locations within each cave for three different periods, from March 2013 to March 2014. Except for Vallgornera, where only one monitoring period was possible, and Artà in which low values were recorded throughout the year, a clear seasonal variability, with higher values during the warm seasons and lower during winter time is prominent. Radon concentrations differed markedly from one cave to another, as well as within the same cave, ranging from below detection limit up to 3060 Bq·m{sup −3}. The results of this study have significant practical implications, making it possible to provide some recommendation to cave administrators and other agencies involved in granting access to the investigated caves. - Highlights: • A survey of radon was carried out in caves from Mallorca, Spain using CR 39 detectors. • Three different seasons are covered: spring, summer, and winter. • Radon level ranges from below detection limit up to 3060 Bq·m{sup −3}. • Seasonal variation is evident (higher values in summer and lower during winter). • Particular recommendations were made to each cave administration.

    Full Text Available Cold Wind Cave, located at elevations ranging between 1,600 and 1,700 m a. s. l. in the main range of the Nízke Tatry Mountains(Slovakia, is linked in origin with the adjacent Dead Bats Cave. Together, these caves form a major cave system located within anarrow tectonic slice of Triassic sediments. Both caves have undergone complex multiphase development. A system of sub-horizontalcave levels characterized by large, tunnel-like corridors was formed during the Tertiary, when elevation differences surroundingthe cave were less pronounced than today. The central part of the Nízke Tatry Mountains, together with the cave systems, wasuplifted during the Neogene and Lower Pleistocene, which changed the drainage pattern of the area completely. The formation ofnumerous steep-sloped vadose channels and widespread cave roof frost shattering characterized cave development throughout theQuaternary.In the Cold Wind Cave, extensive accumulations of loose, morphologically variable crystal aggregates of secondary cave carbonateranging in size between less than 1 mm to about 35 mm was found on the surface of fallen limestone blocks. Based on the C andO stable isotope compositions of the carbonate (δ13C: 0.72 to 6.34 ‰, δ18O: –22.61 to –13.68 ‰ V-PDB and the negative relationbetween δ13C and δ18O, the carbonate crystal aggregates are interpreted as being cryogenic cave carbonate (CCC. Publishedmodels suggest the formation of CCC in slowly freezing water pools, probably on the surface of cave ice, most probably duringtransitions from stadials to interstadials. Though the formation of these carbonates is likely one of the youngest events in thesequence of formation of cave sediments of the studied caves, the 230Th/234U ages of three samples (79.7±2.3, 104.0±2.9, and180.0±6.3 ka are the oldest so far obtained for CCC in Central Europe. This is the first description of CCC formation in one caveduring two glacial periods (Saalian and Weichselian.

    Volcanic caves are filled with colorful microbial mats on the walls and ceilings. These volcanic caves are found worldwide, and studies are finding vast bacteria diversity within these caves. One group of bacteria that can be abundant in volcanic caves, as well as other caves, is Actinobacteria. As Actinobacteria are valued for their ability to produce a variety of secondary metabolites, rare and novel Actinobacteria are being sought in underexplored environments. The abundance of novel Actinobacteria in volcanic caves makes this environment an excellent location to study these bacteria. Scanning electron microscopy (SEM) from several volcanic caves worldwide revealed diversity in the morphologies present. Spores, coccoid, and filamentous cells, many with hair-like or knobby extensions, were some of the microbial structures observed within the microbial mat samples. In addition, the SEM study pointed out that these features figure prominently in both constructive and destructive mineral processes. To further investigate this diversity, we conducted both Sanger sequencing and 454 pyrosequencing of the Actinobacteria in volcanic caves from four locations, two islands in the Azores, Portugal, and Hawai'i and New Mexico, USA. This comparison represents one of the largest sequencing efforts of Actinobacteria in volcanic caves to date. The diversity was shown to be dominated by Actinomycetales, but also included several newly described orders, such as Euzebyales, and Gaiellales. Sixty-two percent of the clones from the four locations shared less than 97% similarity to known sequences, and nearly 71% of the clones were singletons, supporting the commonly held belief that volcanic caves are an untapped resource for novel and rare Actinobacteria. The amplicon libraries depicted a wider view of the microbial diversity in Azorean volcanic caves revealing three additional orders, Rubrobacterales, Solirubrobacterales, and Coriobacteriales.

    Full Text Available Perpetual darkness, high humidity with almost constant geophysical factors are some of the abiotic factors which make the cave ecosystem unique. For any species a high degree of adaptation is always needed to thrive in such an ecosystem. Mammals in general have never adapted to cave life but they can play a major role in the cave ecosystem. Structurally, the Dandak cave has two distinct chambers that are completely different from each other in several geophysical factors. Thus both the cave chambers offer two distinct types of ecological niche. In the present study we found that both chambers of this cave were dominated by mammals all year round. Additionally, the group of mammals using the outer chamber completely differs from the group using the inner one. Possible geophysical factors responsible for such differences are discussed.

    Blind cave fish, with degenerated non-functioning eyes, have evolved to ``see'' their hydrodynamic environment by using the flow receptors of the lateral line system. The hair-cell receptors are encapsulated in a hydrogel-like material, called a cupula, which increases the sensitivity of the hair-cell receptors by coupling their motion to the surrounding flowing media. We characterized the viscoelastic properties and of blind cave fish cupulae by using colloidal-probe spectroscopy in fluid. A photo-patternable hydrogel with similar properties was developed to mimic the fish receptor coupling structure. Flow-based measurements indicated that the hydrogels enhance drag through increased surface area, but also inherent material properties. These bio-inspired structures endowed micro-fabricated flow sensors with sensitivities rivaling that of fish.

    Water and sediment quality are among the most important variables affecting the survival of stygobites. In Tumbling Creek Cave, Taney County Missouri the population of the endangered cave snail, Antrobia culveri, has declined significantly over the past decade. The cause of the population decline is unknown but could be related to the quality of streambed sediment in which the cave snail lives. The objective of this study was to determine the toxicity and concentrations of heavy metals in the sediment of Tumbling Creek Cave and five other caves in Missouri. These sediments were analyzed to assess possible point sources from within the recharge areas of the caves and to provide baseline geochemical data to which Tumbling Creek Cave sediments could be compared. Standard sediment toxicity tests and ICP-MS analysis for heavy metals were conducted. Survival and reproduction of the amphipod, Hyalella azteca, did not differ significantly between cave sediments and a control sediment. However the growth of amphipods differed significantly among sites and was significantly reduced in sediments from Tumbling Creek Cave relative to controls. Concentrations of several metals in sediments differed substantially among locations, with elevated levels of zinc and copper occurring in Tumbling Creek Cave. However, none of the measured metal concentrations exceeded sediment quality guidelines derived to predict probable effects on benthic organisms and correlations between sediment metal concentrations and toxicity endpoints were generally weak. While elevated metal levels may play a part in the cave snail's decline, other factors may be of equal or greater importance. Ongoing analyses of persistent organic contaminants and total organic carbon in cave sediments, along with continued water quality monitoring, may provide data that will allow us to better understand this complicated problem.

    Detailed magnetic survey was performed for caves study in Israel (1995-1996) within the framework of the Beit Shemesh Regional Project (Judean Shephelah). The experience accumulated in Israel we applied later (2010) in two Georgian prehistoric cave sites: Cherula and Kotias-Klde. The magnetic method is based on the contrast in magnetic properties between a target object (e.g., buried archaeological feature) and the host medium (i.e, the surrounding bedrock and soil). The feasibility of the magnetic method for cave revealing was evaluated by magnetic susceptibility (κ) measurements of surrounding soil and rocks, and archaeological features: stones making up the walls, ceramic fragments and cave fill. According to data obtained, the κ of soil within caves (cave fill) is higher than that of surrounding soil. The enhancement of cave fill κ occurs because processes associated with human habitation: repeated heating and accumulation of organic debris. Both these processes provide good conditions for the conversion of the iron oxide found within the soil to a strongly ferromagnetic form (Mullins, 1977; Maher, 1986; Dalan and Banerjee, 1998, Itkis and Eppelbaum, 1999; Itkis, 2003) The presence of highly magnetic ceramics in caves also enhances magnetic contrast between practically non-magnetic bed rock (chalk in Ramat Beit Shemesh Site (Israel) and limestone (Georgian sites) and the cave fill, increasing the potential of the magnetic method to reveal caves (Itkis, 2011). Based on magnetic survey results, an excavation revealed a cave with a large amount of well preserved pottery and finds typical of the Early Bronze Age. Both studied cave sites in Georgia were located in Chiatura region of Imeretia province. Cherula site is a karstic rockshelter with a single chamber, ca 100 sq. m. The site was briefly tested in 1970s'. The area excavated in 2010 went to the depth of 60 cm below the present day surface; the limestone bedrock was not reached. The excavation revealed

    Full Text Available Cioclovina Cave in Romania’s Southern Carpathians is a world-renowned cave site for its paleontological, anthropological, andmineralogical (type locality of ardealite finds. To date, over 25 mineral species have been documented, some unusual for a caveenvironment. This paper presents details on the occurrence of collinsite [Ca2(Mg,Fe2+(PO42·2H2O], atacamite [Cu22+Cl(OH3], andkröhnkite [Na2Cu2+(SO42·2H2O] based on single-crystal X-ray diffraction, electron microprobe, stable isotope analyses, and scanningelectron microscope imaging. This is the first reported occurrence of kröhnkite in a cave environment. Atacamite representsthe weathering product (in the presence of Lower-Cretaceous limestone-derived chlorine of copper minerals washed into the cavefrom nearby ore bodies. Atacamite and kröhnkite have similar sources for copper and chlorine, whereas sodium probably originatesfrom weathered Precambrian and Permian detrital rocks. Collinsite is believed to have precipitated from bat guano in a damp, nearneutralpH environment. The results show the following sequence of precipitation: ardealite-brushite-(gypsum-atacamite-kröhnkite.This suggests that the observed mineral paragenesis is controlled by the neutralization potential of the host-rock mineralogy and theconcentrations of Ca, Cl, Cu, and Na.

    2008-07-01

    Full Text Available Chemical characteristics of permanent stratification in cave pools (meromixis may provide insight into the geochemical origin and evolution of cave pool waters. The objective of this study was to test the hypothesis that some pools in Lechuguilla Cave may be subject to ectogenic meromixis, where permanent chemical stratification is induced by input of relatively saline or fresh water from an external source. However, because organic C concentrations in Lechuguilla waters are low (typically 0.9 m, and are probably the result of localized and transient atmospheric CO2(g concentrations. At LOBG, an EC increase of 93 µS cm-1 at the 0.9-m depth suggests meromictic conditions which are ectogenic, possibly due to surface inflow of fresh water as drips or seepage into a pre-existing layer of higher salinity.

    Caves and mines are considered to be places of especial risk of exposure to (222)Rn. This is particularly important for guides and workers, but also for visitors. In the Extremadura region (Spain), there are two cave systems in which there are workers carrying out their normal everyday tasks. In one, visits have been reduced to maintain the conditions of temperature and humidity. The other comprises several caves frequently visited by school groups. The caves were radiologically characterised in order to estimate the dose received by workers or possible hazards for visitors.

    The Lascaux Cave was discovered in 1940, and by 1960 it had received up to 1800 daily visitors. In 1963, the cave was closed and in 2001 it was invaded by a Fusarium solani species complex which was treated for four years with benzalkonium chloride. However, Lascaux Cave bacteria have only been poorly investigated. Here we show that the cave is now a reservoir of potential pathogenic bacteria and protozoa which can be found in outbreaks linked to air-conditioning systems and cooling towers in community hospitals and public buildings.

    The investigation of 3 caves explored more than 1000 meters in depth in the Dinaric karst area in Croatia, has been in progress for a considerable period of time. These are complex speleological features situated in the longest mountain range of the Dinaric karst, i.e. at the Northern Velebit mountain range. In fact, these caves have been studied for over two decades now. The first one is a cave system of Lukina jama (Luke's Cave) - Trojama cave, which has been investigated until the depth of 1421 meters (Jalžić, 2007; Šmida, 1993). Its total length is 3731 meters and a new expedition will soon continue to investigate this pit through speleodiving in siphons. The second greatest cave by depth is Slovačka jama (Slovak Cave), 1320 meters in depth, with cave chanals measuring 5677 meters in total length. The third greatest cave by depth is the Cave system of Velebita, reaching down to 1026 m in depth, with the chanal length of 3176 meters (Bakšić, 2006a; 2006b). However, another 3 speleological sites, which can rightly be added to those deeper than 1000 m, have recently been discovered. These are three caverns that were discovered during construction of the Sveti Ilija Tunnel that passes through Mt. Biokovo, in the Dinaric karst area. These caverns undoubtedly point to the link with the ground surface, while the rock overburden above the tunnel in the zone where the caverns were discovered ranges from 1250 and 1350 meters. Bats from the ground surface were found in the caverns and, according to measurements, they are situated in the depth from 200 and 300 meters below the tunnel level. This would mean that the depth of these newly found caves ranges from 1450 and 1650 m, when observed from the ground surface. There are several hundreds of known caves in Biokovo, and the deepest ones discovered so far are Jama Mokre noge (Wet Feet Cave) 831 m in depth, and Jama Amfora (Amphora Cave) 788 m in depth (Bockovac, 1999; Bakšić & all, 2002; Lacković & all, 2001

    2010-09-01

    Full Text Available The behaviour of perennial ice masses in karst caves in relation to the outside climate is still not well understood, though a significant potential of the cave-ice for paleo-climate reconstructions could be expected. This study investigates the relationship between weather patterns inside and outside the cave Eisriesenwelt (Austrian Alps and the ice-surface changes of the ice-covered part of the cave from extensive measurements. It is shown that under recent climate the cave ice mass balance is more sensitive to winter climate for the inner parts of the cave and sensitive to winter and summer climate for the entrance near parts of the cave. For recent climate conditions ice surface changes can be well described from cave atmosphere measurements, indicating a clear annual cycle with weak mass loss in winter due to sublimation, stable ice conditions in spring until summer (autumn for the remoter parts of the cave and significant melt in late summer to autumn (for the entrance near parts of the cave. Interestingly, surface ice melt plays a minor role for ablation at the inner parts of the cave. Based on our measurements and other observations it is rather likely that sublimation was the major source for ice loss in Eisriesenwelt since the begin of the 20th century. Build-up of the ice in spring (as expected from theory was not observed as a general feature of the ice dynamics. Generally, the ice body currently appears in a quite balanced state, though the influence of show-cave management on ice mass-balance could not be clearly quantified.

  4. Conservation of prehistoric caves and stability of their inner climate: lessons from Chauvet and other French caves.

    In the last 150 years, some prehistoric painted caves suffered irreversible degradations due to misperception of conservation issues and subsequent mismanagement. These sites presented naturally an exceptional stability of their internal climate allowing conservation in situ of outstanding fragile remains, some for nearly 40,000 years. This is for a large part due to exchanges of air, CO2, heat and water with the karstic system in which these caves are included. We introduce the concept of underground confinement, based on the stability of the inner cave climate parameters, especially its temperature. Confined caves present the best conservative properties. It is emphasized that this confined state implies slow exchanges with the surrounding karst and that a stable cave cannot be viewed as a closed system. This is illustrated on four case studies of French caves of various confinement states evidenced by long term continuous monitoring and on strategies to improve their conservation properties. The Chauvet cave presents optimal conservation properties. It is wholly confined as shown by the stability of its internal parameters since its discovery in 1994. In Marsoulas cave, archeological works removed the entrance scree and let a strong opening situation of the decorated zone. Remediation is expected by adding a buffer structure at the entrance. In Pech Merle tourist cave, recurrent painting fading was related to natural seasonal drying of walls. Improvement of the cave closure system restored a confined state insuring optimal visibility of the paintings. In Gargas tourist cave, optimization of closures, lighting system and number of visitors, allowed it to gradually reach a semi-confined state that improved the conservation properties. Conclusions are drawn on the characterization of confinement state of caves and on the ways to improve their conservation properties by restoring their initial regulation mechanisms and to avoid threats to their stability.

    Due to their exceptional significance for cultural and natural heritage, the Škocjan Caves were entered on UNESCO's list of natural and cultural world heritage sites in 1986. Park Škocjan Caves is located in South Eastern part of Slovenia. It was established with aim of conserving and protecting exceptional geomorphological, geological and hydrological outstanding features, rare and endangered plant and animal species, paleontological and archaeological sites, ethnological and architectural characteristics and cultural landscape and for the purpose of ensuring opportunities for suitable development, by the National Assembly of the Republic of Slovenia in 1996. Park Škocjan Caves established monitoring that includes caves microclimate parameters: humidity, CO2, wind flow and radon concentration and daughter products. The approach in managing the working place with natural background radiation is complex. Monitoring of Radon has been functioning for more than ten years now. Presentation will show the yearly dynamic observed in the different parts of the caves, related to radon daughter products and other microclimatic data, beside the most convenient measuring technique. Implementing the Slovene legislation in the field of radiation protection, we are obligated to perform special measurements in the caves and also having our guides and workers in the caves regularly examined according to established procedure. The medical exams are performed at Institution of Occupational Safety, Ljubljana in order to monitor the influence of Radon to the workers in the cave. The equivalent dose for each employed person is also established on regular basis and it is part of medical survey of workers in the caves. The survey will be described along with education of the staff working in the caves in the field of radiation protection. An overview of Slovene legislation with practical example on implementation will be demonstrated in the case of Škocjan Caves where the managing

    2016-09-01

    Full Text Available Scientific exploration of marine cave environments and anchialine ecosystems over recent decades has led to outstanding discoveries of novel taxa, increasing our knowledge of biodiversity. However, biological research on underwater caves has taken place only in a few areas of the world and relevant information remains fragmented in isolated publications and databases. This fragmentation makes assessing the conservation status of marine cave species especially problematic, and this issue should be addressed urgently given the stresses resulting from planned and rampant development in the coastal zone worldwide. The goal of the World Register of marine Cave Species (WoRCS initiative is to create a comprehensive taxonomic and ecological database of known species from marine caves and anchialine systems worldwide and to present this as a Thematic Species Database (TSD of the World Register of marine Species (WoRMS. WoRCS will incorporate ecological data (e.g., type of environment, salinity regimes, and cave zone as well as geographical information on the distribution of species in cave and anchialine environments. Biodiversity data will be progressively assembled from individual database sources at regional, national or local levels, as well as from literature sources (estimate: >20,000 existing records of cave-dwelling species scattered in several databases. Information will be organized in the WoRCS database following a standard glossary based on existing terminology. Cave-related information will be managed by the WoRCS thematic editors with all data dynamically linked to WoRMS and its team of taxonomic editors. In order to mobilize data into global biogeographic databases, a Gazetteer of the Marine and Anchialine Caves of the World will be established. The presence records of species could be eventually georeferenced for submission to the Ocean Biogeographic Information System (OBIS and constitute an important dataset for biogeographical and

    Palmer, Arthur N.; Palmer, Margaret; Paces, James B.

    2016-01-01

    Cave development in the Madison aquifer of the Black Hills has taken place in several stages. Mississippian carbonates first underwent eogenetic (early diagenetic) reactions with interbedded sulfates to form breccias and solution voids. Later subaerial exposure allowed oxygenated meteoric water to replace sulfates with calcite and to form karst and small caves. All were later buried by ~2 km of Pennsylvanian–Cretaceous strata.

    2007-01-01

    Full Text Available The Kanaan cave is situated at the coastal zone, north of Beirut City (capital of Lebanon. The cave is located within the upper part of the Jurassic Kesrouane Formation (Liassic to Oxfordian which consists mainly of micritic limestone. Twenty seven cave pearls were subjected to petrographic (conventional and scanning electron microscopy and geochemical analyses (major/trace elements and stable isotopes. The cave pearls were found in an agitated splash-pool with low mud content. They are believed to have formed through chemical precipitation of calcite in water over-saturated with calcium. The nucleus and micritic laminae show δ18OV-PDB values of about -5.0‰ and δ13C V-PDB values of -11.8‰, while the surrounding calcite spar laminae resulted in δ18OV-PDB ranging between -5.3 and -5.2‰, and δ13C V-PDB between -12.3 and -12.1‰. A genesis/diagenesis model for these speleothems is proposed involving recrystallization which has selectively affected the inner layers of the cave pearls. This is chiefly invoked by sparry calcite crystals ‘invading’ the inner micrite cortical laminae and the nuclei (cross-cutting the pre-existing mud-envelopes, and the slight depletion in δ18O values from inner to outer cortical layers. The calculated δ18OV-SMOW of the water (-4.2‰ matches with data on meteoric water signature for the central eastern Mediterranean region.

    A rare localization of adenocarcinoma in Meckel's cave is reported in a 58-year-old woman, who had a 5-month history of pain and altered sensation in the second division of the left trigeminal nerve. Removal of the lesion was achieved by a subtemporal route. Histology showed this to be an adenocarcinoma. The patient underwent investigations for a primary tumor; the investigations were all negative, and the patient was subsequently treated with a course of radiotherapy. At 4-month follow-up, there was no evidence of recurrence, and she remains symptomatically well. The various mechanisms of secondary localization are discussed.

  20. Carbonate Platform Margin Slope Characteristics of Cambrian Chefu Age in Baojing-Fenghuang and Adjacent Areas, Western Hunan, China

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The Cambrian paleogeography in south China can be divided into Yangtze platform, platform margin slope (including upper slope and lower slope) and basin. The carbonate gravity deposits are well developed there, particularly in the Yangtze platform adjacent areas. This paper mainly deals with declivity fan characters of the Chefu age in Fenghuang adjacent areas, western Hunan Province. According to their distribution and thickness, three main declivity fans have been divided in the study areas,namely, Dama ( ∈ c-dsf), Machong ( ∈ c-msf) and Huangheyuan ( ∈ c-hsf) declivity fans. Each fan's characters are described in detail in this paper. Based on their distribution range, scale and fossiliferous layers, two peak periods (fair developmental period) are distinguished: (1) Linguagnostus reconditus Zone (time), and (2) Glyptagnostus reticulatus Zone (time). They were characterized by huge thick limestone breccia layers (single layer 3-4 rn thick) and closely spaced spread. Besides, there are also two developmental periods: (1) Lejopyge laevigata- Proagnostus bulbus Zone (time), and (2) Agnostus inexpectans-Proceratopyge protracta Zone (time) to Erixanium Zone (time) to Corynexochus plumula-Sinoproceratopyge cf. kiangshanensis Zone (time), while Glyptagnostus stolidotus Zone (time) was an interstitial period (without or rare limestone breccias). All these features may verify the relative movement of the earth crust and paleoclimate variety of the Chefu age in the study areas.

    The matching relationship between coal cutting and caving in fully mechanized top-coal caving face is analyzed in detail from the angle of reliability. The coupling equation of reliability is established correspondingly, and the mathematical equation of the coefficient of velocity matching of coal cutting and caving is obtained, which meets a certain reliability demand for making the working procedure of coal caving not influence coal cutting of coal-cutter. The results show that the relationship between the coefficient of the velocity matching and the reliability of coal cutting and caving system is linear on the whole when R<0.9. It is pointed out that different numerical value should be selected for different coal face according to different demand for reliability.

    Hubei and Hunan Provinces were sparsely populated at the beginning of the Qing Dynasty, however, most of southern Hunan had occurred because of the land development all overpopulation problem. This directly affected the local traditional agricultural economy and caused hardship and impinged upon the people's food supply. Southern Hunan was the first region to introduce maize, sweet potatoes and other high-yield upland grain crops. In Hubei and Hunan Provinces, such man-land relationships had objectively stimulated diversified economic development in the region. The two crops were widely planted after the middle of the Qing Dynasty, the hardship of food scarcity in southern Hunan was effectively alleviated. Southern Hunan also experienced rapid population growth. The introduction of new crops and the demographic expansion were powerful factors promoting the further development of the local community's economy. What needs to be pointed out is that population pressure and labor substitution forced economic development, but there was no general improvement in the living standards of the people. These economic developments had the obvious historical limitations.%清初两湖地区尚属地广人稀,但湘南大部却因为田土开发殆尽而出现了人口过剩问题,这直接影响到地方的传统农业经济和造成了民食之困,湘南因此成为两湖最早引种玉米、甘薯等高产旱地粮食作物的地区,但这种人地紧张关系也在客观上刺激了该地区的多元化经济发展。清中期以后,上述两种作物的广泛种植,使湘南的民食之困得到有效缓解,人口亦出现了高速增长,这些都有力促进了地方社会经济的再发展。需要指出的是,这种受人口压力所迫而以“使用劳力”方式为主的经济发展,并没有普遍提高民众的生活水平,因此具有明显的历史局限性。

  6. Middle Pleistocene hominin teeth from Longtan Cave, Hexian, China.

    Song Xing

    Full Text Available Excavations at the Longtan Cave, Hexian, Anhui Province of Eastern China, have yielded several hominin fossils including crania, mandibular fragments, and teeth currently dated to 412 ± 25 ka. While previous studies have focused on the cranial remains, there are no detailed analyses of the dental evidence. In this study, we provide metric and morphological descriptions and comparisons of ten teeth recovered from Hexian, including microcomputed tomography analyses. Our results indicate that the Hexian teeth are metrically and morphologically primitive and overlap with H. ergaster and East Asian Early and mid-Middle Pleistocene hominins in their large dimensions and occlusal complexities. However, the Hexian teeth differ from H. ergaster in features such as conspicuous vertical grooves on the labial/buccal surfaces of the central incisor and the upper premolar, the crown outline shapes of upper and lower molars and the numbers, shapes, and divergences of the roots. Despite their close geological ages, the Hexian teeth are also more primitive than Zhoukoudian specimens, and resemble Sangiran Early Pleistocene teeth. In addition, no typical Neanderthal features have been identified in the Hexian sample. Our study highlights the metrical and morphological primitive status of the Hexian sample in comparison to contemporaneous or even earlier populations of Asia. Based on this finding, we suggest that the primitive-derived gradients of the Asian hominins cannot be satisfactorily fitted along a chronological sequence, suggesting complex evolutionary scenarios with the coexistence and/or survival of different lineages in Eurasia. Hexian could represent the persistence in time of a H. erectus group that would have retained primitive features that were lost in other Asian populations such as Zhoukoudian or Panxian Dadong. Our study expands the metrical and morphological variations known for the East Asian hominins before the mid-Middle Pleistocene and

    2002-07-01

    An investigation of radon levels in the caves of Creswell Crags, Derbyshire, an important Site of Special Scientific Interest (SSSI) shows that the Lower Magnesian Limestone (Permian) caves have moderate to raised radon gas levels (27-7800 Bq m{sup -3}) which generally increase with increasing distance into the caves from the entrance regions. This feature is partly explained in terms of cave ventilation and topography. While these levels are generally below the Action Level in the workplace (400 Bq m{sup -3} in the UK), they are above the Action Level for domestic properties (200 Bq m{sup -3}). Creswell Crags has approximately 40,000 visitors per year and therefore a quantification of effective dose is important for both visitors and guides to the Robin Hood show cave. Due to short exposure times the dose received by visitors is low (0.0016 mSv/visit) and regulations concerning exposure are not contravened. Similarly, the dose received by guides is fairly low (0.4 mSv/annum) due in part to current working practice. However, the risk to researchers entering the more inaccessible areas of the cave system is higher (0.06 mSv/visit). This survey also investigated the effect of seasonal variations on recorded radon concentration. From this work summer to winter ratios of between 1.1 and 9.51 were determined for different locations within the largest cave system.

    2013-01-01

    The Jam Up Cave and Pine Crest 7.5-minute quadrangles are located in south-central Missouri within the Salem Plateau region of the Ozark Plateaus physiographic province. About 2,400 to 3,100 feet (ft) of flat-lying to gently dipping Lower Paleozoic sedimentary rocks, mostly dolomite, chert, sandstone, and orthoquartzite, overlie Mesoproterozoic igneous basement rocks. Unconsolidated residuum, colluvium, terrace deposits, and alluvium overlie the sedimentary rocks. Numerous karst features, such as sinkholes, caves, and springs, have formed in the carbonate rocks. Many streams are spring fed. The topography is a dissected karst plain with elevations ranging from about 690 ft where the Jacks Fork River exits the northeastern corner of the Jam Up Cave quadrangle to about 1,350 ft in upland areas along the north-central edge and southwestern corner of the Pine Crest quadrangle. The most prominent physiographic feature is the valley of the Jacks Fork River. This reach of the upper Jacks Fork, with its clean, swiftly-flowing water confined by low cliffs and bluffs, provides one of the most beautiful canoe float trips in the nation. Most of the land in the quadrangles is privately owned and used primarily for grazing cattle and horses and growing timber. A large minority of the land within the quadrangles is publicly owned by the Ozark National Scenic Riverways of the National Park Service. Geologic mapping for this investigation was conducted in 2005 and 2006.

    Many biospeleological studies focus on organisms that are exclusive inhabitants of the subterranean realm, but organisms that are not obligate cave-dwellers are frequent in caves, and may account for a substantial portion of biomass. Moreover, several taxa that are usually epigeous are regularly found inside caves, but for most of them it is unknown whether they accidentally enter them, or whether they actively select caves for specific environmental features. In this study we analysed the community of non-strict cave-dwelling organisms (amphibians, gastropods, spiders and orthopterans) in 33 caves from Central Italy, to assess how environmental factors determine community structure. Cave features strongly affected the distribution of the taxa considered. The combined effect of cave morphology and microclimate explained nearly 50% of the variation of community structure. Most of community variation occurred along a gradient from deep, dark and humid caves, to dry caves with wider entrances and extended photic areas. Most of species were associated with humid, deep and dark caves. Most of the non-troglobiont amphibians and invertebrates did not occur randomly in caves, but were associated to caves with specific environmental features. Analysing relationships between cave-dwelling species and environmental variables can allow a more ecological and objective classification of cave-dwelling organisms.

  15. Calcite Farming at Hollow Ridge Cave: Calibrating Net Rainfall and Cave Microclimate to Dripwater and Calcite Chemical Variability

    Stable isotope (δ18O and δ13C) and trace element records in cave speleothems are often interpreted as climate changes in rainfall amount or source, cave air temperature, overlying vegetation and atmospheric pCO2. However, these records are difficult to verify without in situ calibration of changes in cave microclimate (e.g., net rainfall, interior ventilation changes) to contemporaneous variations in dripwater and speleothem chemistry. In this study at Hollow Ridge Cave (HRC) in Marianna, Florida (USA), cave dripwater, bedrock, and modern calcite (farmed in situ) were collected in conjunction with continuous cave air pCO2, temperature, barometric pressure, relative humidity, radon-222 activity, airflow velocity and direction, rainfall amount, and drip rate data [1]. We analyzed rain and dripwater δD and δ18O, dripwater Ca2+, pH, δ13C and TCO2, cave air pCO2 and δ13C, and farmed calcite δ18O and δ13C to examine the relationships among rainwater isotopic composition, cave air ventilation, cave air temperature, calcite growth rate and seasonal timing, and calcite isotopic composition. Farmed calcite δ13C decreases linearly with distance from the front entrance to the interior of the cave during all seasons, with a maximum entrance-to-interior gradient of Δδ13C = -7‰ . A whole-cave "Hendy test" at distributed contemporaneous farming sites reveals that ventilation induces a +1.9 ± 0.96‰ δ13C offset between calcite precipitated in a ventilation flow path and out of flow paths. Farmed calcite δ18O exhibits a +0.82 ± 0.24‰ offset from values predicted by both theoretical calcite-water calculations and by laboratory-grown calcite [2]. Unlike calcite δ13C, oxygen isotopes show no ventilation effects and are a function only of temperature. Combining our data with other speleothem studies, we find a new empirical relationship for cave-specific water-calcite oxygen isotope fractionation across a range of temperatures and cave environments: 1000 ln α = 16

    The main particularity of karst systems is their hierarchical organization as three-dimensional network of conduits behaving as drain. They are recognized as having a major influence on fluid flow at reservoir scale. However, a karstic network is generally hardly continuously observable and their great intrinsic heterogeneity makes their characterization very complex. This media can be only observed by speleological investigation, conditioned to human possibilities. As a result, only few parts can be observed and therefore it is required to model the non-observable parts for reservoir characterizations. To provide realistic 3D models, non-observable karstic features will be generated using parameters extracted from observed ones. Morphometric analysis of the three-dimensional karstic network provides quantitative measures that can (i) give information on speleogenesis processes, (ii) be used to compare different karst systems, (iii) be correlated with hydrogeological behavior and (iii) control the simulation of realistic karst networks. Recent work done on the subject characterize the karstic network as a whole, without genetic a-priori. However, most of observable caves appears to have a polygenic history due to modifications in boundary conditions and some different karst features can be observed in a same cavity. To study the geometrical organization of caves, we propose to analyze 3D speleological topographies for which speleogenetic context is known. This way, it is possible to characterize karst features according to speleogenetic processes. Several morphometric descriptors have been calculated on three-dimensional topographies provided by speleological works. Some parameters describe the existence of preferential direction of karstification and preferential flow paths, other parameters describe the complexity, geometry and connectivity of the three-dimensional karstic networks. Through the study of fifteen different caves, 150km of 3D data have been analyzed

  17. Deposition of calcium carbonate in karst caves: role of bacteria in Stiffe's cave.

    Full Text Available Bacteria make a significant contribution to the accumulation of carbonate in several natural habitats where large amounts of carbonates are deposited. However, the role played by microbial communities in speleothem formation (stalactites, stalagmites etc. in caves is still unclear. In bacteria carbonate is formed by autotrophic pathways, which deplete CO2 from the environment, and by heterotrophic pathways, leading to active or passive precipitation. We isolated cultivable heterotrophic microbial strains, able to induce CaCO3 precipitation in vitro, from samples taken from speleothems in the galleries of Stiffe’s cave, L’Aquila, Italy. We found a large number of bacteria in the calcite formations (1 x 104 to 5 x 109 cells g-1. Microscopic examination, in laboratory conditions at different temperatures, showed that most of the isolates were able to form calcium carbonate microcrystals. The most crystalline precipitates were observed at 32°C. No precipitation was detected in un-inoculated controls media or in media that had been inoculated with autoclaved bacterial cells. X-ray diffraction (XRD analysis showed that most of the carbonate crystals produced were calcite. Bacillus strains were the most common calcifying isolates collected from Stiffe’s Cave. Analysis of carbonate-solubilization capability revealed that the non-calcifying bacteria were carbonate solubilizers.

    Caves offer a stable and protected environment from harsh and changing outside prevailing conditions. Hence, they represent an interesting habitat for studying life in extreme environments. Here, we report the presence of a member of the ancient eukaryote red algae Cyanidium group in a coastal cave of the hyperarid Atacama Desert. This microorganism was found to form a seemingly monospecific biofilm growing under extremely low photon flux levels. Our work suggests that this species, Cyanidium sp. Atacama, is a new member of a recently proposed novel monophyletic lineage of mesophilic "cave" Cyanidium sp., distinct from the remaining three other lineages which are all thermo-acidophilic. The cave described in this work may represent an evolutionary island for life in the midst of the Atacama Desert. ?? Springer Science + Business Media, LLC 2009.

    The term hot cave is used to describe some subterranean chambers in the Neotropics that are characterized by constantly high ambient temperatures generated by the body heat of high densities of certain bat species. Many of these species have limited geographic ranges, and some occur only in the hot-cave environment. In addition to the bats, the stable microclimate and abundant bat guano provides refuge and food for a high diversity of invertebrates. Hot caves have so far been described in the Caribbean and in a few isolated locations from Mexico to Brazil, although there is some evidence that similar caves may be present throughout the tropics. The existing literature suggests these poorly known ecosystems, with their unique combination of geomorphology and bat-generated microclimate, are particularly sensitive to disturbance and face multiple threats from urbanization, agricultural development, mining, and tourism.

  5. Review of Hydraulic Fracturing for Preconditioning in Cave Mining

    2016-12-01

    Hydraulic fracturing has been used in cave mining for preconditioning the orebody following its successful application in the oil and gas industries. In this paper, the state of the art of hydraulic fracturing as a preconditioning method in cave mining is presented. Procedures are provided on how to implement prescribed hydraulic fracturing by which effective preconditioning can be realized in any in situ stress condition. Preconditioning is effective in cave mining when an additional fracture set is introduced into the rock mass. Previous studies on cave mining hydraulic fracturing focused on field applications, hydraulic fracture growth measurement and the interaction between hydraulic fractures and natural fractures. The review in this paper reveals that the orientation of the current cave mining hydraulic fractures is dictated by and is perpendicular to the minimum in situ stress orientation. In some geotechnical conditions, these orientation-uncontrollable hydraulic fractures have limited preconditioning efficiency because they do not necessarily result in reduced fragmentation sizes and a blocky orebody through the introduction of an additional fracture set. This implies that if the minimum in situ stress orientation is vertical and favors the creation of horizontal hydraulic fractures, in a rock mass that is already dominated by horizontal joints, no additional fracture set is added to that rock mass to increase its blockiness to enable it cave. Therefore, two approaches that have the potential to create orientation-controllable hydraulic fractures in cave mining with the potential to introduce additional fracture set as desired are proposed to fill this gap. These approaches take advantage of directional hydraulic fracturing and the stress shadow effect, which can re-orientate the hydraulic fracture propagation trajectory against its theoretical predicted direction. Proppants are suggested to be introduced into the cave mining industry to enhance the

    In the last 50 years during the construction of almost all the tunnels in the Croatian Dinaric Karst thousands of caves have been encountered that represented the major problems during the construction works. Geological features (fissures, folding, faults, etc.) are described in this contribution, together with the hydrogeological conditions (rapid changes in groundwater levels). Special engineering geological exploration and survey of each cave, together with the stabilization of the tunnel ceiling, and groundwater protection actions according to basic engineering geological parameters are also presented. In karst tunneling in Croatia over 150 caves longer than 500 m have been investigated. Several caves are over 300 m deep (St. Ilija tunnel in Biokovo Mt), and 10 are longer than 1000 m (St.Rok tunnel, HE Senj and HE Velebit tunnels in Velebit Mt, Ucka tunnel in Ucka Mt, Mala kapela tunnel in Kapela Mt, caverns in HE Plat tunnel etc). Different solutions were chosen to cross the caves depending on the size and purpose of the tunnels (road, rail, pedestrian tunnel, or hydrotechnical tunnels). This is presentations of interesting examples of ceiling stabilization in big cave chambers, construction of bridges inside tunnels, deviations of tunnels, filling caves, grouting, etc. A complex type of karstification has been found in the cavern at the contact between the Palaeozoic clastic impervious formations and the Mesozoic complex of dolomitic limestones in the Vrata Tunnel and at the contact with flysch in the Učka Tunnel. However, karstification advancing in all directions at a similar rate is quite rare. The need to have the roadway and/or tunnel above water from a spring is the biggest possible engineering-geological, hydrogeological and civil engineering challenge. Significant examples are those above the Jadro spring (Mravinci tunnel) in flysch materials or above the Zvir spring in Rijeka (Katarina tunnel), and in fractured Mesozoic carbonates.

    Full Text Available The secondary minerals from Iza Cave result from the interactions of karst water and/or cave atmosphere with a variety of sedimentaryand metamorphic rocks. The cave passages expose at various extents Eocene limestones and conglomerates, Oligocene blackshales, Upper Precambrian micaschists, marble and dolomitic marble and associated ore deposits. Twelve secondary mineralsidentified in the cave (carbonates, sulfates, phosphates, oxides and hydroxides, and silicates are presented in this study. Calcite,aragonite, gypsum, brushite and hydroxylapatite are the components of common speleothems in the limestone, dolomite andconglomerate areas of the cave. Ankerite crusts are related to areas with pyrite mineralization within the metamorphic carbonaterocks. Goethite, jarosite, hematite and gypsum form various speleothems in the sectors within micaschists and conglomerates. Largeweathering deposits occurring in passage areas developed within micaschists consist of illite, kaolinite, jarosite, goethite, gypsumand alunite. The extent of the weathering deposits occurring on non-karst rocks in the underground environment makes this cave aparticularly interesting site for studies of water-rock interactions.

    The 5 provinces in central China have similar economic standard and large educational scale. The overall development level of ICT in elementary education in central China is inferior to medium level in nationwide scope. Besides, there is considerably gap among different provinces and different districts in the same province. Based on the spot check data of 14 districts from the 5 provinces, the paper made comparative analysis on the current situation of ICT development level in elementary education in central China. This signiifcant factors which impact the development of the ICT in elementary education in central China include:(1) The disparities of digital resources become obvious. The vast majority of primary and secondary schools haven’t set up school-based resource center, and the situation of high quality digital resources supported by teaching material has become worse; (2) The recognition degree of the information-based teaching application have been gradually improved. However, the application has not been infused into the link of teaching; (3) The ICT management in elementary education is in the initial stage. The application and popularization of ICT management in elementary education should be reinforced; (4) The ICT development level in provincial capital city and side-provincial capital cities are signiifcantly higher than ordinary city. The difference of ICT development of elementary education among districts is obvious.%我国中部5省经济水平相当,基础教育规模接近且总量较大,基础教育信息化整体发展水平在全国范围内属于中等偏下,省域间、省域内的差异较大。基于中部5省14市(区)的基础教育信息化抽样调查数据,该文对我国中部地区省域间、省域内的基础教育信息化发展现状及其差异性进行对比分析。研究发现影响中部省份基础教育信息化发展的显著因素包括:(1)数字资源整体差异较大,绝大部分中小学校未建

    Isolated caves are a special cave type common in most karst terrains, formed by prolonged slow water flow where aggressivity is locally boosted. The morphometry and distribution of isolated caves are used here to reconstruct the paleohydrology of a karstic mountain range. Within a homogenous karstic rock sequence, two main types of isolated caves are distinguished, and each is associated with a special hydrogeologic setting: maze caves form by rising water in the confined zone of the aquifer, under the Mt. Scopus Group (Israel) confinement, while chamber caves are formed in phreatic conditions, apparently by lateral flow mixing with a vadose input from above.

    Carbon isotope composition of speleothems and their parent drip water reflects the isotope composition of the atmospheric CO2, the soil and the host rock and can sometimes be influenced even by the cave atmosphere. Owing to the fact that 14C in the bedrock has long decayed, the bedrock derived carbon content of the seepage water can be considered as inactive or "dead carbon". The initial dead carbon proportion (dcp) of a stalagmite or tufa layer, caused by the incorporation of the inactive carbon, can be calculated with the help of the C-14 level differences between the contemporary atmosphere and the formed stone carbonate. The revolutionary technological advances of 14C (AMS) have brought the possibility of analysing 14C dynamics of karst systems due to the small amount of demanded material. The Baradla-Domica Cave is the largest cave of Gömör-Torna Karst, a karst area situated in the northeast of Hungary, and located on the Slovakian-Hungarian borderland. The approximately 26 km long cave is a typical example of multi-level speleogenesis. As a case study we have investigated several recent (age < 50 years) and older (age about 10-11 kyrs) stalagmites and recent drip water, some freshwater tufa samples and the recent cave air carbon-dioxide of the Baradla-cave to study the carbon dynamics and dead carbon level there. According four modern stalagmites (formed 1991-2004) the current dcp is very small in Baradla Cave (3-7%). Stalagmites deposited in Holocene (U/Th dated) were also characterized by very small dead carbon contents (1-11% dcp). Outside the cave a dpc about 20-25% was found in a freshwater tufa sample. This relatively low dead carbon content might be either explained by the thinness of the limestone bedrock above (56-80 m) or the relatively fast infiltration conditions, or their combined effect. Cave air is enriched in CO2 (2-5 times higher than in natural air, not homogenous) but the source of this surplus CO2 is not the limestone according its

    Full Text Available Volcanic caves have been little studied for their potential as sources of novel microbial species and bioactive compounds with new scaffolds. We present the f irst study of volcanic cave microbiology from Canada and suggest that this habitat has great potential for the isolation of novel bioactive substances. Sample locat ions were plot ted on a contour map that was compiled in ArcView 3.2. Over 400 bacterial isolates were obtained from the Helmcken Falls cave in Wells Gray Provincial Park, British Columbia. From our preliminary screen, of 400 isolates tested, 1% showed activity against extended spectrum ß-lactamase E. coli, 1.75% against Escherichia coli, 2.25% against Acinetobacter baumannii, and 26.50% against Klebsiella pneumoniae. In addition, 10.25% showed activity against Micrococcus luteus, 2% against methicillin resistant Staphylococcus aureus, 9.25% against Mycobacterium smegmatis, 6.25% Pseudomonas aeruginosa and 7.5% against Candida albicans. Chemical and physical characteristics of three rock wall samples were studied using scanning electron microscopy and f lame atomic absorption spectrometry. Calcium (Ca, iron (Fe, and aluminum (Al were the most abundant components while magnesium (Mg, sodium (Na, arsenic (As, lead (Pb, chromium (Cr, and barium (Ba were second most abundant with cadmium (Cd and potassium (K were the least abundant in our samples. Scanning electron microscopy (SEM showed the presence of microscopic life forms in all three rock wall samples. 16S rRNA gene sequencing of 82 isolates revealed that 65 (79.3% of the strains belong to the Streptomyces genus and 5 (6.1% were members of Bacillus, Pseudomonas, Nocardia and Erwinia genera. Interestingly, twelve (14.6% of the 16S rRNA sequences showed similarity to unidentif ied ribosomal RNA sequences in the library databases, the sequences of these isolates need to be further investigated using the EzTaxon-e database (http://eztaxon-e. ezbiocloud.net/ to determine whether

    Sulphuric acid speleogenesis (SAS) related to the upwelling of acid water enriched in H2S and CO2 represents an unusual way of cave development. Since meteoric infiltration waters are not necessarily involved in speleogenesis, caves can form without the typical associated karst expressions (i.e. dolines) at the surface. The main mechanism of sulphuric acid dissolution is the oxidation of H2S (Jones et al., 2015) which can be amplified by bacterial mediation (Engel et al., 2004). In these conditions, carbonate dissolution associated with gypsum replacement, is generally believed to be faster than the normal epigenic one (De Waele et al., 2016). In Italy several SAS caves have been identified, but only few systems have been studied in detail: Frasassi and Acquasanta Terme (Marche)(Galdenzi et al., 2010), Monte Cucco (Umbria) (Galdenzi & Menichetti, 1995), and Montecchio (Tuscany) (Piccini et al., 2015). Other preliminary studies have been carried out in Calabria (Galdenzi, 2007) and Sicily (De Waele et al., 2016). Several less studied SAS cave systems located in South Italy, and in particular in Apulia (Santa Cesarea Terme), Sicily (Acqua Fitusa, Acqua Mintina) and Calabria (Mt. Sellaro and Cassano allo Ionio) have been selected in the framework of a PhD thesis on SAS caves and their speleogenesis. Using both limestone tablet weight loss (Galdenzi et al., 2012) and micro erosion meter (MEM) (Furlani et al., 2010) methods the dissolution rate above and under water in the caves will be quantified. Geomorphological observations, landscape analysis using GIS tools, and the analysis of gypsum and other secondary minerals (alunite and jarosite) (stable isotopes and dating) will help to reconstruct the speleogenetic stages of cave formation. Preliminary microbiological analysis will determine the microbial diversity and ecology in the biofilms.

    In 1965, Ciur-Izbuc Cave in the Carpathian Mountains of Romania was discovered to contain about 400 ancient human footprints. At that time, researchers interpreted the footprints to be those of a man, woman and child who entered the cave by an opening which is now blocked but which was usable in antiquity.
