Full textAbstract:
Between October 2001 and the end of 2003 there was a close co-operation between the Geological Survey of Denmark and Greenland (GEUS) and the Geological Survey Department of Ghana (GSD), as part of a project to enhance GSD’s institutional capabilities and effectiveness, mainly in the fields of management, geological mapping, map production and data handling. During this period a team of geologists, GIS (Geographic Information System) and database experts as well as administrative staff from GEUS have visited GSD, and GSD officers have visited GEUS in Copenhagen. The main obstacles to GSD becoming an effective organisation are its status as a department under the Ghana Ministry of Mines, insufficient funding by the government, and poor remuneration of its professional staff. To overcome these obstacles, attempts are being made to change the status of GSD from a ‘civil servant organisation’ into a semiautonomous institution, which will permit the Survey to generate funding for its core activities by providing services to outside organisations, and pay better salaries to its personnel. Despite many problems, geological mapping has been resumed and three new geological maps have been produced by GSD during the project and stored in GIS format. A mapping manual has been prepared, and the structure and ‘Mission and Vision Statements’ for the Survey have been revised.

The systematic investigation of the geology of Greenland for the State was continued in 1985 by the Geological Survey of Greenland (GGU). The investigations encompassed basic research and geological mapping as well as investigations in applied disciplines. Field work, mainly in the months of June, July and August, was carried out by seventy-five scientists and technicians, half of whom belong to the Survey's staff. In addition to the GGU parties several groups from other institutions worked in close collaboration with GGU. The areas of field activity reported on in 1985 are indicated on fig. 1. During 1985 the Survey was partly reorganised, and it is now built up of six main units: Department of Stratigraphy and Structural Geology, Department of Precambrian Geology, Department of Geochemistry, Department of Mineral Resources, Department of Petroleum Geology and Department of Glaciology and Glacial Geology. The administration, computing facilities and editorial staff are directly responsible to the Director.

Full textAbstract:
The New York State Museum was created by State legislation in 1870 out of the old State Cabinet, which held the specimens collected by the State Geological and Natural History Survey, James Hall, then State Geologist and Palaeontologist within the Survey, was named Director of the Museum. Hall's need to possess and study vast quantities of paleontological specimens required space for collections storage and processing. His collections became the major supply of specimens for the Cabinet and eventually the Museum. After the original Survey was disbanded, in the early 1840's, Hall's presence gave the Cabinet a definite geological character. As the chief geological scientist, Hall considered the geological research of the Cabinet and later the Museum as a product of the "Geological Survey of New York," even though no formal designation of such a unit was ever proclaimed by state legislation. After all, other states were forming geological research units similar to Hall's and calling them geological surveys. It made sense for good communications for Hall and his predecessor State Geologists to refer to their staff as the New York State Geological Survey. Eventually, through a series of other legislative acts, most importantly in 1904 and 1945, the Museum was made the formal administrative home for the Geological Survey and, thus, its guardian. Museum Directors, therefore, have had the principle role in determining the fate of geological and paleontological research within the Geological Survey, After 1926, when the first non-geologist became director, the Museum's research scope grew faster in other natural and social history areas, such as botany, entomology, zoology, archaeology, ethnology, and history. This expansion is exemplified by the addition of a State Historian to the Education Department in 1895. During its 150-year history the Geological Survey has moved six times, and it is now housed in the Cultural Education Center in the Governor Nelson A. Rockefeller Empire State Plaza, Albany, New York.

Full textAbstract:
A simple postal survey of 73 museums, heritage centres, individuals and other establishments was conducted to assess the state and status of geological collections across the Republic of Ireland. There were 31 locations with a collection, assessed under three categories; 1) educational or institutional geological department, 2) County Museum/Local authority funded museum and 3) other collections including private ones. Excepting the National Museum, the specialised geological museums were mainly directed towards internal functions, with little outreach or community emphasis, and with a resource based lack of curatorial strength. The County Museums had little knowledge or practical concern for their geological collections, but a desire for assistance was clear. With the other collections the lack of appropriate knowledge to assess or use the geological collections was apparent. All but the specialised geological museums commonly confused archaeological specimens with geological ones and this misapprehension is evidently widely held. Some preliminary recommendations for improving the status of geological collections are suggested.

In the beginning of the 1990’s, the Department of Geochemistry of Utrecht University started a series of geochemical surveys of the Leeward Islands of the Antilles that form part of the Kingdom of the Netherlands. Apart from seeking a nice, warm fieldwork environment, the undertaking was motivated by the deficits in infrastructure and financial resources of these islands, which precluded the authorities to undertake such a survey on their own. By then, the International Geological Correlations Programme (IGCP; Darnley et al., 1995) had just been established to address the need for standardised geochemical databases worldwide; the then Geological Survey of the Netherlands (RGD) - now the TNO-Institute of Applied Geosciences (TNO-NITG) - participated in this programme from the start.

Objectives: The aim of this evaluation was to identify pitfalls in medical prescriptions of uncomplicated urinary tract infections in government healthcare facilities in Zambia.
Design: The study was a cross sectional study and healthcare facilities were conveniently sampled.
Main outcome measures: Rate of compliance to Zambia national prescribing guidelines.
Results: A total of 42 (75.0%) out of 56 students participated in the survey of whom 66.7% were males. Findings in this study has demonstrated significant drug misuse and over-prescription as participants were healthy individuals. Only 75.6% of prescriptions indicated patient’s name and very small proportions of prescriptions (11.5%) indicated patients’ address. In addition, relatively small proportion of prescriptions (68.8%) had generic names and many prescriptions (58.1%) had large blank spaces left. Furthermore, relatively large proportion of prescriptions were not signed (10.7%) and not dated (12.0%). Almost half of the prescriptions (47.6%) did not show prescribers’ names and only small proportions of prescriptions had precribers’ identification number (24.%) and address or department (21.5%) indicated.
Conclusions: Overall, the evaluation has shown poor prescribing practices and not in compliance with national prescribing guidelines among prescribers in government healthcare facilities in Zambia.

Full textAbstract:
James Merrill Safford (1822-1907), famous for geological investigations of Tennessee, taught chemistry and biology, as well as geology, for 52 years. He held administrative posts in medicine, and his teaching, even of geology, was mostly to would-be physicians, engineers and pharmacists. His education in Silliman's laboratory at Yale, during 1847, probably was the key to his success. From 1848 to 1873 he taught full-time at Cumberland University in Lebanon, Tennessee, except for leave in 1854-56 to work for the geological survey of Tennessee. During the Civil War hiatus, 1862-1866, he taught preparatory languages on a private basis, operated his farm, and investigated oil and gas properties. After 1875, Safford held part-time teaching posts. He was a half-time Professor of Geology and Biology at Vanderbilt University and taught chemistry as a proprietor in a Medical Department jointly operated by Vanderbilt and the University of Nashville. He was also secretary of the Medical Faculty and Dean of the Pharmacy Department at Vanderbilt. Safford was a pleasant, friendly man, who quoted classical poetry and lead early morning prayers. Through 1869, his professional contributions mainly consisted of survey work in geology. Later he mainly applied geology to health, agriculture, and resource development.

To mark the 150th anniversary of the Geological Survey of Canada (GSC), as well as Canada’s 125th birthday and the 50th anniversary of the Alaska Highway, the Royal Canadian Geographical Society, in partnership with the Geological Survey of Canada, the Surveys, Mapping and Remote Sensing Sector (both of the Department of Energy, Mines and Resources) and the Canadian Parks Service (Environment Canada) undertook an expedition to determine the exact elevation of Mount Logan. In addition to measuring the elevation of the mountain the expedition also collected rock samples and positioned brass survey markers on the mountain. Since the first recorded sighting of the mountain in 1890 a number of different values for the height of the mountain have been quoted. Most of these values centered around 5950 metres. However a value of 6050 metres was very widely used. The differences in elevation can in large measure be attributed to the difficulties associated with conducting surveys in the extreme remoteness of the Saint Elias Mountains combined with measuring techniques of varying accuracies. The Logan '92 Expedition was the first expedition to attempt to measure the height of Mt. Logan using the Global Positioning System (GPS).

AbstractIn March 1984 the British Geological Survey commenced an environmental geological study of parts of west Wiltshire and south east Avon for the Department of the Environment. The objective of this study was to collect the available geological data relevant to the area, and to present them as a series of thematic maps accompanied by a descriptive report and a database/archive of the data used.The output is intended to be used by land-use planners. It is designed simultaneously to be understandable by people not trained in geology and yet to contain detailed information required by specialists concerned with the environment and its development. The 14 maps which were produced describe themes which include solid lithostratigraphy, drift deposits, the inferred distribution of Great Oolite Freestone, the inferred distribution of fuller’s earth, groundwater, ground conditions in relation to groundwater, geotechnical properties of bedrock and superficial deposits, landslipped and cambered strata, distribution of slope angle, and mining.Although the task was primarily a desk study, it was found necessary to carry out a small amount of field survey to re-interpret the foundered strata to the north-west of Bath. This re-survey has been presented in a style consistent with the mapping of the rest of the study area. A fifteenth map showing the result of the re-interpretation of the foundered strata was produced as a supplement to the main report.This paper describes the methods and the results of this study and comments on the implications of the technique for land-use planning.

The high-resolution terrain model has varied usages including development planning, engineering works, environmental management, disaster management, urban planning, irrigation, geological study, archeological study and cadastral application. Currently, this data is not available for Nepal and it has also hindered the socio and economic development of the country. Airborne Lidar is economically cost-effective and viable means for topography related data collection. Lidar which is an acronym for Light Detection and Ranging is an active remote sensing technology in which Laser beams are used for surveying and mapping. The Survey Department of Nepal has taken initiative to prepare the High-Resolution DTM and Orthophoto of about 20,000 square kilometres of Nepal using Lidar surveying and mapping. Survey Department is conducting a LiDAR survey in the western terai regions of Nepal from Chitwan to Kanchanpur district. Airborne LiDAR survey data along with a very high resolution (0.15 m) orthophoto shall be generated. Further, processing of LiDAR points data will generate a highly precise digital terrain model of 1 m grid data having an accuracy of 0.25 m and finally 0.5 m contour interval data. This endeavor is one of the milestones in the surveying and mapping sector of Nepal and it will have far-reaching consequence in the social and economic development of Nepal.

Full textAbstract:
The South West Hub (SWH) project is Australia's first carbon capture and storage (CCS) flagship project. Managed by the WA government's Department of Mines and Petroleum (DMP), the SWH is assessing the geological properties of a proposed CO2storage site in the southwest of WA to determine its feasibility. This includes collating detailed geological information, partnering with researchers, acquiring baseline data, consulting with communities and stakeholders, and negotiating land access. Recent activities have included a 2D seismic survey in 2011, drilling of a stratigraphic well (Harvey–1) in 2012 and a comprehensive (115 km2) 3D seismic survey in 2014. A further drilling program is planned for the fourth quarter of 2014 until the first quarter of 2015. The 2014 3D seismic survey has been described as one of the most complex land-based seismic surveys conducted in Australia due to environmental factors, and competing land-use and land-access constraints. This extended abstract reviews the recent 3D seismic survey, including the development of the project's scope and procurement processes through to community engagement and implementation, and outlines how the lessons are being incorporated into the upcoming drilling program. It will also discuss legacy issues that have impacted on community attitudes and confidence, and the challenges of working with potentially hostile communities, and also demonstrate how the project adopted and adapted best practice engagement guidelines and toolkits for CCS projects to achieve successful outcomes.

Abstract The alligator snapping turtle Macrochelys temminckii is the largest freshwater turtle in North America and humans seek it as a food source, primarily in Louisiana. Scientists point to decades of intensive commercial harvest of alligator snapping turtles as a cause of population declines. The Louisiana Department of Wildlife and Fisheries initiated a head-start program for alligator snapping turtles and released 53 head-started juveniles at seven sites along an approximately 5.7-km stretch of Bundick Creek in southwest Louisiana between November 2015 and October 2016. Before release, department personnel measured, weighed, and marked all alligator snapping turtles with both an internal passive integrated transponder tag and a numbered external tag. In 2018, the U.S. Geological Survey initiated a turtle trapping survey at those seven release sites targeting the head-started alligator snapping turtles. In 1 wk of trapping effort at each site, we recorded 69 turtle captures comprising seven species, including 15 alligator snapping turtles (representing 12 individuals). Of those 12 individuals, 8 were head-started juveniles and 4 were native to the creek. A landowner captured an additional head-started juvenile alligator snapping turtle during our trapping and we took measurements before its release. A minimum of 17% of head-started alligator snapping turtles survived since release, and we trapped most captured head-started individuals near their release site; the captured individuals exhibited growth consistent with other studies, indicating acclimatization to their new environment. Three head-started alligator snapping turtles had their external tags entangled in the net mesh, and two of these turtles drowned. An additional two head-started individuals lost their external tags in the natural environment prior to their capture in this study. The Louisiana Department of Wildlife and Fisheries discontinued the use of external tags based on our findings, as these tags were detrimental to the health of head-started turtles.

AbstractMaps and plans represent essential tools of the trade for planners and applied earth scientists alike, and thematic maps produced by geologists should be able to be understood by planners. Geology, geotechnics, geomorphology, hydrogeology and related sciences can provide essential data on some of the constraints to development and resources for development. Recognition of these permits safer, more cost- effective planning and development, and allows rational decisions to be taken as far as the exploitation of resources is concerned. Consequently the Department of Environment had been commissioning research to investigate the best means of collecting, collating, interpreting and presenting, in sets of maps and reports, geological results of direct applicability to land-use planning. For example, some years ago initial studies in thematic mapping were undertaken by the British Geological Survey and more recently a number of private consultants have carried out such work. Unfortunately, the results of some of these surveys have not, as yet, been published.

Full textAbstract:
The Hydraulic Engineering Circular 18 (HEC-18) pier scour prediction equation is the most widely used pier scour prediction equation in the United States, if not the world, and understanding the equation’s performance is of interest to the bridge engineering community. Previous evaluations of the equation’s performance were limited to smaller sets of laboratory and field data. In 2014, the U.S. Geological Survey, in cooperation with the South Carolina Department of Transportation, published a U.S. Geological Survey pier scour database, consisting of 569 laboratory and 1,858 field measurements of pier scour. This extensive database is a valuable resource for evaluating the HEC-18 pier scour equation, which is the primary focus of the investigation presented in this paper. Although comparing predicted and measured values is a common method for evaluating the performance of a prediction equation, the present investigation used a different approach and evaluated the HEC-18 equation by comparing selected data from the USGS database with the dimensionless relationship used to develop the original equation. This alternative approach highlighted some of the strengths and weaknesses of the equation, which are not as evident in the more common approach of comparing predicted and measured values. The findings of the investigation are presented in this paper.

Full textAbstract:
Global positioning systems (GPS) technology, developed by the Department of Defense, enable accurate documentation of Cartesian coordinates anywhere on the earth's surface. Surveying, mapping, positioning, and subsequent management of weed infestations can be expedited with this technology. Positions and boundaries of infestation may be located with 10-m or better accuracy while the GPS receiver is continuously moving, and with 2-m or better accuracy with brief stops for repeated sampling. GPS data agreed closely with U.S. Geological Survey data. Coordinates for a weed infestation may be relocated for treatment, evaluation or other purposes. Basic geographic information systems (GIS) map features from Digital Line Graph (DLG), Topologically Integrated Encoding and Reference Systems (TIGER) and other sources of information may be used to fully integrate delimiting survey results from GPS readings in order to develop weed management plans.

ABSTRACT Military applications of geology became apparent within the United Kingdom during the nineteenth century, and were developed during the First World War and more extensively during the Second, incidentally by some officers with links to Canada. In the nineteenth century, three Royal Engineer major-generals with geological interests had served there briefly: Joseph Ellison Portlock (1794–1864) helped to stem invasion of Upper Canada by the United States Army in 1814, pioneer geological survey in Ireland from 1826, and promote knowledge of geology amongst British Army officers; Frederick Henry Baddeley (1794–1879) helped to pioneer geological studies in south-east Canada in the 1820s; Richard John Nelson (1803–1877) served in Canada after mapping the geology of Jersey in 1828 and making geological observations in Bermuda. During the First World War, Tannatt William Edgeworth David (1858–1934), a Welsh-born Australian and from 1916 to 1918 the senior of two geologists serving with the British Army on the Western Front, had a Canadian military family link through his mother; and Reginald Walter Brock (1874–1935), Dean of Applied Science at the University of British Columbia and a distinguished Canadian geologist, interrupted his career for infantry service in Europe but was used as a geologist from mid-1918, in Palestine. During the Second World War, the British military geologist Frederick William Shotton (1906–1990) provided geological advice to, amongst other units, Canadian forces who generated thematic maps for parts of northern France that predicted ‘going’ (conditions affecting cross-country vehicle mobility) to follow the D-Day Allied landings in Normandy. In 1943, Thomas Crawford Phemister (1902–1982), Professor and Head of the Department of Geology and Mineralogy at the University of Aberdeen in Scotland but from 1926 to 1932 an associate professor at the University of British Columbia, as an ‘emergency’ Royal Engineers captain founded the Geological Section of the Inter-Service Topographical Department, a unit whose reports and thematic maps provided terrain intelligence for Allied forces in both Europe and the Far East from a base in England, within the University of Oxford. John Leonard Farrington (1906–1982), an undergraduate student from 1923 to 1928 of Brock and/or Phemister at the University of British Columbia, co-founded the Section and soon succeeded Phemister as its head, from 1944 to 1945 in the rank of major. Soon after 1945, military geologists became established in continuity within the British Army.

In an effort to investigate the deep geological structure in the broader area of central-western Attica, that suffered severe damage during the destructive Athens earthquake of September 7th, 1999, the Department of Geophysics-Geothermics of the Faculty of Geology and Geoenvironment of Athens University, in collaboration with the Geodynamic Institute of National Observatory of Athens and the Department of Geological Sciences of Durham University, carried out a combined geophysical survey. For the first time in Attica, seismic and gravity geophysical methods were applied along profiles, in such an extensive scale. Within the framework of this investigation the following tasL· were accomplished: a) Three (3) seismic lines of about 30 kilometres of total length, two (2) in the area of Thriassion plain and one (1) along the Parnitha-Krioneri-Drosia-Ekali-Dionysos axis (Attica plain) and b) 338 gravity measurements distributed along eight (8) gravity profiles, four (4) of which in Thriassion plain, three (3) in Petroupoli-Aharnes-Thrakomakedones region (Attica plain) and one (1) along Parnitha-Krioneri-Drosia-Ekali-Dionysos axis (Attica plain). Preliminary results of the geophysical investigation combined with existing geological and tectonic data are presented in this paper. Significant variation in the elevation of the alpine basement has been detected, expressed by manifestation of low and high subsurface areas which are well correlated with existing fault zones. In the area of Thriassion plain the thickness of post-alpine sediments is estimated of a few hundred meters (<500 meters) and huge thickness of several hundred meters (-800 meters) of post-alpine sediments were detected in Thrakemakedones and Krioneri areas. The relief of alpine basement is more intense in fault zones areas, such as Thriassion plain (WNW-ESE), Pathitha and Kifissos (NE-SW) as well as along the fault zone outline the Fili and Aharnes graben and is covered by postalpine formations

Aiming to provide a global diagnosis of the actual threat of pollution to the most important aquifers of the State of São Paulo, Brasil, due to its intensive industrialization and agriculture, three government institutions -the Instituto Geologico (Geological Institute), the CETESB (Environmental Sanitary Technology Company) and the DAEE (Water and Eleotrical Energy Department) - carried out a regional survey to define the aquifers' vulnerability to pollution and for recording and ranking the potential contaminant sources. This paper describes the results of this survey, excluding the metropolitan area of the city of São Paulo. More than 500 industries were recorded and ranked according to their low, moderate or high potential contaminant load for impacting groundwater. Thirty - one aquifer units were defined and a 1:500.000 scale vulnerability map was produced. Critical areas were defined and recommended as being priority sites for the adoption of control measures.

Full textAbstract:
A metallogenic belt is a metallogenic geological unit with rich mineral resources and potential. The study of metallogenic belts can provide a basis for mineral monitoring and deployment. Research of the metallogenic belt in Zhejiang Province is too deficient. This paper uses the domestic high-resolution satellite data from 2018 to 2021 to carry out the application of remote sensing in a comprehensive geological survey on different metallogenic belts in Zhejiang Province. The survey results show that the area of each metallogenic belt is decreasing year by year, which shows that under the regulation of the natural resources department, the unqualified mining activities in key control areas such as nature reserves, ecological red lines, and the Yangtze River economic belt are timely stopped and forcibly closed, so that the mining development order gradually tends to be good. The restoration and control points show a trend of less in the south and more in the north, mainly distributed in the economically developed areas of the northern, central, and eastern plains of Zhejiang Province. According to the statistics of the degree of mine environment restoration and treatment (treatment percentage), the Taishun-Zhoushan metallogenic belt is the highest, and treatment percentage from 2018 to 2021 is 83.01%, 80.07%, 76.91%, and 73.78%, respectively. For four consecutive years, the number of restoration and treatment projects has been increasing, and the restoration and treatment area has increased significantly. The countermeasures and suggestions for mine environmental restoration in the metallogenic belt have been put forward. In the mining area, if the geological environment is good, the rainfall is sufficient, and so on, then natural re greening can be considered. According to the brief evaluation criteria, a total of 2983 mines can be restored naturally, including 311 in the Si’an-Changxing metallogenic belt, 325 in the Lin’an-Huzhou metallogenic belt, 387 in the Kaihua-Hangzhou metallogenic Belt, 598 in the Quzhou-Shaoxing metallogenic belt, 765 in the Longquan-Shangyu metallogenic belt, and 597 in the Taishun-Zhoushan metallogenic belt. A total of 1911 mines were involved within 1 km of the “three zones and two lines”. There are 50 places in the Si’an-Changxing metallogenic belt, 151 in the Lin’an-Huzhou metallogenic belt, 236 in the Kaihua-Hangzhou metallogenic belt, 326 in the Quzhou-Shaoxing metallogenic belt, 513 in the Longquan-Shangyu metallogenic belt, and 635 in the Taishun-Zhoushan metallogenic belt. The survey results and suggestions can provide scientific basis and important reference for the local mining administration department to carry out the restoration of the mine ecological environment in metallogenic belts, and they are of great significance to promote the wide and in-depth application and technological progress of remote sensing technology.

Full textAbstract:
Background: Stress among health care workers is a subject that has received much attention worldwide. However, there have been few studies that address the issue of work-related stress among health care workers in Africa and in Zambia in particular. There was an urgent need to study burnout at the University Teaching Hospital in order to have concrete evidence for planning and policy purposes in order to help address some of the human resource for health problems in Zambia. This study sought to measure the levels of work-related burnout among doctors at the University Teaching Hospital and to investigate associated factors.
Methods: This was a cross-sectional study. Data was collected by means of a self-administered survey using Maslach Burnout Inventory provided by mindgarden.com. Data analysis was done using guidelines as set out in the Maslach Burnout Inventory manual using Epi-info software. Cross tabulations and chi-square and statistical analysis tests were done in order to establish whether there were any statistically significant associations between levels of burnout and other variables such as sex, age, seniority, department and marital status, among others.
Results: More than half, 54.4.%, of doctors studied at the University Teaching Hospital experienced average or high levels of emotional exhaustion with 44.8% experiencing average or high levels of depersonalisation and 66.4% experiencing average or low levels of personal accomplishment. Personal accomplishment was the subscale with the highest indication of burnout, followed by emotional exhaustion and depersonalisation. There were no significant associations between demographic and individual work factors studied and burnout levels.
Conclusions: Burnout levels are significant at the University Teaching Hospital. There were no significant associations between demographic and individual work factors studied and burnout levels. This study has highlighted that burnout is a problem that needs to be addressed at the hospital and further investigation is required to assess what factors maybe contributing to it, particularly those related to the work environment, since personal and demographiccharacteristics did not show any associations to burnout.

Full textAbstract:
The Tennessee Division of Geology has a close, long-term relationship with the educational establishment in Tennessee that has changed in nature over the years but remains strong. Gerard Troost, the first State Geologist, was a college professor, as was his successor, James M. Safford, and, more recently, L. C. Glenn. From 1909 to 1923 the affairs of the State Geological Survey were overseen by a Geological Commission that included, ex officio, the President of the University of Tennessee, the Chancellor of Vanderbilt University, and the Vice Chancellor of the University of the South; then, from 1923 to 1937, the Division of Geology was administratively part of the State Department of Education. Since becoming part of the Conservation Department in 1937 the Division has served an educational function by publishing both scholarly and popular works on the geology of the state; by answering inquiries on every subject from paleontology to water-witching; by advising news media on geology-related stories; by giving talks to school, museum, and other groups; and by close cooperation with university geology departments on research projects. The Division has had a strong role in graduate education, particularly at the Master's level, by conducting field excursions for students, financing theses through student mapping projects, by loans of field equipment, and serving as informal thesis advisors. Long-term assistance to geology departments has also included part-time employment of professors as consultants, publication of studies by professors and students, and part-time teaching by Division staff members. Most of these forms of educational assistance have suffered in recent years, due to budget cuts and loss of staff positions.

This article analyzes the experience of geological exploration and construction on the example of the city of Norilsk, and also discusses their problems. In 1935, it was decided to build the Norilsk Metallurgical Plant and the village of Norilsk was founded. During the geological survey and construction, many problems arose, these include: - the spread of permafrost soils, and subsequently the thawing of soils acting as the base of buildings and structures; - a small number and scattered location of rocky soils suitable for use as a base; - limited technology capabilities; - long time and huge costs when using as a base, rocky soils. Those problems mostly arose due to the lack of experience in building foundations on permafrost, Norilsk is the first experience in this regard. To solve the problem of permafrost, the Norilsk Integrated Department of the Krasnoyarsk Institute "Promstroyniiproekt" was formed in 1959. The solution to the problem was found at that time by Mikhail Vasilyevich Kim, who was appointed to the post of head. The method of pile foundation in permafrost consisted in freezing the pile into the frozen ground. Thus, this method allowed not only to solve the problem with the construction of foundations on permafrost, but also to use it for construction purposes.

Abstract Historical fossil assemblages from the Lower Jurassic to Lower Cretaceous of the Sankt Veit Klippen Unit (SVK) on the western outskirts of Vienna were re-evaluated. Collections of the material from the St. Veit Klippen Unit comprise 3497 specimens. An appropriate nomenclature was used, and the taxonomy was partly revised. Historical collections from Franz Toula (1845–1920) and Friedrich Trauth (1883–1967) were investigated in the collections of the Natural History Museum Vienna, the Geological Survey Vienna, the Department of Geology and the Department of Palaeontology (both University Vienna). Additional collections were studied in the district museums Hietzing (13th district Vienna) and Liesing (23rd district Vienna), in the district municipal office of Hietzing and in the Wienerwald Museum (Eichgraben, Lower Austria). The study area is situated in the easternmost part of the St. Veit Klippen Unit in the Wienerwald (Vienna Woods), part of the 13th Viennese district Hietzing. New data allowed a revision of the biostratigraphy of several lithological units of the SVK. Two main fossil complexes could be distinguished: 1) the Hohenauer Wiese assemblage from the wildlife park Lainz (= “Lainzer Tiergarten”) and 2) the Glasauer quarry assemblage from St. Veit.

ABSTRACT Various State of Alaska agencies, including the Alaska Department of Environmental Conservation (ADEC), are currently investigating 136 legacy wells within the National Petroleum Reserve-Alaska (NPR-A) and surrounding lands. These legacy wells were drilled between 1944 and 1981 by federal agencies, including the United States Navy and United States Geological Survey, to explore oil reserve potential and to develop drilling techniques for Alaska's arctic. In 2004, 2010 and 2013 the Bureau of Land Management released preliminary studies describing potential environmental risks at each site. Many wells include historic reserve pits, flare pits, crude and diesel oil releases, and discarded solid waste. Tundra damage and potential residual contamination are of great concern. Due to their remote locations, information on the current status of waste is limited. Regulatory agencies are developing a cleanup plan that is appropriate for their remote, Arctic environment.

Full textAbstract:
This study was to examine the Public Sector Reform Programme and implementation of the Efficacy of the Integrated Financial Management Information Systems (IFMIS) in Zambia. The focus is on the country's central government with 1300 users of IFMIS in forty-four sites. The study used a quantitative research design to draw conclusions from a sample of 150 day-to-day users of IFMIS. Data was collected through a survey analysed using descriptive and causal-effect relationships. The system usage is far from satisfactory with misapplication of funds, and challenges in cooperating with partners. The public did not derive satisfaction in this outcome. However, IFMIS influences public resource management processes through ease of access to information, quick retrieval, easy tracking of documents and provision of an audit trail, among others. The system provides restricted access to the IFMIS system, creates the order of operations, defines and reduces the roles and duties of different users, which reduces the level of risk. Some users doubted the system’s ability to detect and report fraud cases. This study, therefore, recommends that IFMIS should be upgraded to protect documents from being attacked by viruses or getting lost, including stronger fraud detection, reporting and a broad application and use of IFMIS in all country departments with new features for fraud detection and reports to facilitate quick remedy. Lastly, the IFMIS should be decentralized to each department to ensure the processes of the supply chain are secured and efficient.

Abstract Southern Mountains, Yogyakarta Special Region is a zone that extends from the south-eastern part of Yogyakarta Special Region to the east along the southern coast of East Java. From the hydrogeological map, it is known that the area is an area of scarce groundwater. This study aims to determine the potential for groundwater in these areas. The identification of groundwater potential is carried out using the Groundwater Potentiality Index (GPI) method by referring to 5 determining parameters: lineaments, lithology, drainage, topography, and rainfall. Lineament, drainage, and topography data were obtained from the Indonesia Geospatial Portal and the Digital Elevation Model (DEM) belonging to the Indonesian Geospatial Information Agency. The lithological data is obtained from data from the Geological Survey Centre, Geological Agency, Ministry of Energy, and Mineral Resources in the form of Geological Maps of Remote Sensing Image Interpretation Results. Rainfall data were obtained from reports from the Serayu Opak River Basin Office and the Public Works, Housing, and Energy Department of Mineral Resources Yogyakarta Special Region. The evaluation of parameters reveals that even in the scarce groundwater zones, estimation of area with possible of groundwater can be classified into five classes of groundwater potential index, namely: very low (<56.25), low (56.25-90), medium (90-123.75), high (123.75-157.5), and very high (> 157.5). In the next step of research the validation may be conducted on a high and very high GPI value whether their are really is associated with the presence of springs and wells. If it is correlated, future exploration of groundwater in this area will be focused and successful.

The present work was developed in outcrops of Santa Maria region, southern Brazil, Rio Grande do Sul State. Statistic evaluations were applied in different rock types. The possibility to distinguish different geologic units, sedimentary and volcanic (acid and basic types) by means of the statistic analyses from the use of airborne gamma-ray spectrometry integrating potash radiation emissions data with geological and geochemistry data is discussed. This Project was carried out at 1973 by Geological Survey of Brazil/Companhia de Pesquisas de Recursos Minerais. The Camaquã Project evaluated the behavior of potash concentrations generating XYZ Geosof 1997 format, one grid, thematic map and digital thematic map files from this total area. Using these data base, the integration of statistics analyses in sedimentary formations which belong to the Depressão Central do Rio Grande do Sul and/or to volcanic rocks from Planalto da Serra Geral at the border of Paraná Basin was tested. Univariate statistics model was used: the media, the standard media error, and the trust limits were estimated. The Tukey’s Test was used in order to compare mean values. The results allowed to create criteria to distinguish geological formations based on their potash content. The back-calibration technique was employed to transform K radiation to percentage. Inside this context it was possible to define characteristic values from radioactive potash emissions and their trust ranges in relation to geologic formations. The potash variable when evaluated in relation to geographic Universal Transverse Mercator coordinates system showed a spatial relation following one polynomial model of second order, with one determination coefficient. The statística 7.1 software Generalist Linear Models produced by Statistics Department of Federal University of Santa Maria/Brazil was used.

Low levels of fluoride in drinking water is healthy for the teeth enamel, however, higher concentrations result in dental fluorosis with prolonged exposures leading to skeletal fluorosis. Fluoride removal capacities of ceramic filters using aluminosilicates (Anfoega clay, Kibi kaolin, Laterite soil and Termitaria earth) samples from Ghana Geological Survey Department have been investigated and analysed for possible application in the Bongo District of Ghana noted forhavinghigh fluoride concentration in its ground water. Batch sorption studies conducted revealed that the amount of fluoride ions removed increased proportionally with increasing filter thickness, temperature and contact time to an optimum value. Using particle size ranges of <355μm and 1cm filter thickness at room temperature, the percentage of fluoride removed by the samples reached an optimum value after 70mins. Increases in filter thickness, contact time or temperatureincreased the amount of fluoride ions removedand the time required to reach the optimum value reduced significantly.

AbstractThe UK Department of Energy and Climate Change (DECC) commissioned the British Geological Survey (BGS) to summarize the available geological knowledge, integrate new seismic mapping and well analysis, and make preliminary in-place resource assessments for the three most prospective areas onshore Britain to foster a greater understanding of the unconventional shale resource potential in advance of the 14th Landward Licensing Round.The first study, published in June 2013, reviewed the Carboniferous Bowland–Hodder shales across central Britain where a large volume of in-place gas was assessed to be present. The second study, of the Jurassic shale of the Weald Basin in southern England, published in May 2014, concluded that owing to insufficient burial there was no significant Jurassic shale gas potential, but there could still be shale oil resources at several levels in the centre of the basin. The third study, published in June 2014, covered the Midland Valley of Scotland where both oil and gas potential in Carboniferous shales was identified.A large volume of in-place gas and oil resource has been assessed to be present. However, not enough is known at the time of writing to estimate a recovery factor or to estimate potential producible reserves. This paper summarizes the results of the BGS reports and their impact on the subsequent licensing process in England.

An attempt has been made to calibrate magnitudes of local earthquakes recorded by National Seismological Centre (NSC) of the Department of Mines and Geology (DMG), Nepal with other magnitudes of corresponding earthquakes [eported by International Seismological Centre (ISC), UK, and United States Geological Survey (USGS), USA. Local magnitudes (ML) are used from NSC, corresponding surface wave magnitudes (Ms) and body-wave magnitudes (Mb) are used from catalog of ISC and moment magnitude (Mw) is used from catalog of the USGS.
After regression analysis, it has been found that the local magnitude s (ML) reported by NSC are slightly larger than Ms, Mb and Mw in all cases. ML, on average, is larger by an amount of about 0.5, than Ms; with an uncertainty of 0.7. Similarly, ML is larger than corresponding Mb by an amount of about 0.6 and the uncertainty is about 0.5. Likewise, ML is larger than Mw by about 1.0 and the corresponding uncertainty is 0.7.

AbstractIt is becoming increasingly important to delimit resources of aggregates, especially near densely populated industrial areas, where the demand is greatest. Knowledge of these resources is needed by both planners and the aggregates industry. The British Geological Survey (BGS) has recently carried out detailed surveys in the south Midlands and Welsh Borderland, under contracts from the Department of the Environment. The areas are covered by the Warwick, Redditch, Tewkesbury, Worcester and Hereford 1:50 000 geological maps, most of which had not previously been geologically surveyed in detail. The most important element in the surveys, therefore, was the 1:10 000 geological mapping, involving studies of the superficial deposits and solid rocks. There are extensive spreads of sand and gravel in all these districts, deposited by glacial, fluvioglacial, periglacial or fluvial activity.In addition to the mapping, boreholes were drilled in some areas to supplement the data already available. The Industrial Minerals Assessment Unit (IMAU) of the BGS also carried out a shallow drilling programme as part of a resource assessment in the Redditch-Rugby area.Between Redditch and Solihull, various drilling, geophysical and remote-sensing techniques were used by IMAU to evaluate their use in assessing sand and gravel resources. The most effective method proved to be shallow resistivity measurements, using an Offset Wenner system, backed up by cable percussion drilling. The same resistivity technique proved to be especially useful, in the Worcester, Hereford and Henley-in-Arden areas, for locating sand and gravel beneath alluvial silts.Gravel deposits near Worcester were investigated using an EM31 conductivity meter. The local geology, comprising river terrace gravels overlying mudstone bedrock, is ideally suited to this method. Thickness variation in the gravel deposits could be obtained quickly by grid traverses, covering the area at a rate of about 1 square kilometre per day.

Abstract: Certain people belongs to geological survey department spent their most of time in jungles, deserts and see shores for surveying Surface mapping, ores and minerals exploration, costal environment survey, etc. they are assigned with countless jobs, in this regard they are away from their homes for weeks together and roaming in out doors.While surveying near to their temporary camps, they can carry this system for lighting purpose or for some other reason. They need not carry the system in their hands, since the system is having motorized wheels, and with the help of a remote. Since all electrical appliances like fans, drill motors, lights, etc are designed to operate at 220v ac at 50Hz same source is generated through inverter designed with PWM chip. PWM IC is used to generate 50Hz ac pulses and its output is used to drive the step up transformer through power mosfets. The drive stage is configured in push-pull mode of operation such that power losses can be minimized and inverter efficiency can be increased. Remote control unit is designed with RF modules and it is operated using encoder and decoder chips.The idea is to generate conventional energy using non-conventional sources of energy.

Abstract The shoreline of Kalutara, Sri Lanka has become more prone to erosion because of environmental changes caused by natural and anthropogenic factors including climate change. The study aimed to assess and map the physical and social vulnerability to coastal erosion in the shoreline between the Kalu and Bolgoda River mouths in Southwest Sri Lanka. This study relied on secondary data sources such as topographic, digitized, and satellite maps obtained from the Survey Department and the website of the United States Geological Survey (USGS). The Coastal Vulnerability Index (CVI) was calculated using only five variables namely coastal slope, geology, soil, shoreline change (End Point Rate), and Land Use and Land Cover (LULC). On the other hand, for the Social Coastal Vulnerable Index (SVI), several socioeconomic variables were examined. Kalutara North and Thotupala have been identified as having a higher risk of Physical and Social Coastal Vulnerability. This research, therefore, revealed that the coastal zone along Kalutara – Panadura in Sri Lanka is vulnerable both physically and socially due to the accelerating rate of coastal erosion. Because of the potential effects of climate change and rising sea levels, this scenario would pose a serious threat to the environment and communities in the foreseeable future.

Full textAbstract:
The paper covers historical material on the formation and development of schools of thought in geotechnical engineering in Kharkiv National University of Civil Engineering and Architecture (formerly known as Kharkiv Civil Engineering Institute), which came into being in 1934 with the establishment of the Department of Bases and Foundations. Particular emphasis is laid upon some personalities of the department; they are outstanding scientists and professors, such as F.O. Belyakov, S.Z. Saidakovsky, I.Ya. Luchkovsky, G.G. Strizhelchyk and others, who made a significant contribution to the formation of schools of thought in geotechnical engineering at the university. A particular contribution of the created research laboratory and the developed equipment for field methods of research into physical and mechanical properties of soils of bases for the foundations of building structures is singled out in the development of scholarly knowledge. The achievements of the renamed Department of Geotechnics, Underground and Hydrotechnical Structures are listed as of today, such as renovation of the educational and research laboratory of “Geotechnical Survey”, which has a governmental certification and allows scientists and students to perform high-quality laboratory work and conduct a full range of engineering and geological and hydrogeological surveys for construction; creation of a new research and technical subdivision of the department known as “Center for monitoring buildings and structures”, which conducts an instrument monitoring of the stress-strain state of the bases and foundations of construction projects using advanced equipment and software packages; availability of an IT classroom and licensed software, including SOFISTIK, a powerful German design software package, which allows researchers to provide high-level research and technical support for designing construction projects. The paper also clearly shows the advantages of training scientific staff and civil engineers in specialties 192 “Construction and Civil Engineering” and 194 “Hydrotechnical Engineering, Water Engineering and Water Technology" and, as a result, a considerable demand for KhNUCEA graduates from employers.

Full textAbstract:
Purpose: The majority of district-level carbon stock estimates for the local forests are obsolete and incomplete. Because of this, decisions made by policymakers have an impact on forest regions. This study establishes some baseline information for estimates of the above-ground carbon stocks in the nearby Kanonge forest.
Methodology: The use of a sequential explanatory design allowed the quantitative data to be collected and analysed first, and the qualitative data to be collected and analysed later to explain why the variables identified in the first phase are significant predictors of the aboveground carbon stocks. As a result, 15 sample plots were used in the forest, 286 households were sampled on villages within 5km radius to the forest, 8 key informants were sampled from Forestry Department, 8 from Ministry of Agriculture, 10 village head persons and 10 forest users. The quantitative data was collected using forest inventories and household surveys while qualitative data was collected using key informants’ interviews. The allometric equations were used to analyse forest inventory data, logistic regression was used to analyse household survey data and the key informant interviews were analysed using thematic analysis.
Findings: The results show that, the above ground biomass and carbon stock were 276.19 ± 7.41 and 155.76 ± 4.18 t ha-1 respectively. The logistic regression results shows that Forest products use, farm size, household size and forest clearing where the significant predictors of the reduction of the aboveground carbon stocks. The results further reveals that there is inadequate intersectoral coordination at district and local level.
Unique Contribution to Theory, Practice and Policy: Further study should be done to find strategies to sustain carbon stocks in the forest while maintaining the use of the forest by the local communities. This study provides accurate estimates of forest and tree carbon stocks and supports in the development of the district integrated plan in accordance with decentralized policy. This information can therefore be used at the district and federal levels in various carbon programs like REDD+, offering the district the chance to participate in the fight against climate change and global warming.

As the World Wide Web (WWW) expands, information is rapidly becoming more accessible. Using satellite data previously required high-end computers running complex imaging software, sophisticated downloading equipment, and high monetary support. Satellite data is now available on the internet for little or no cost and can be handled on standard desktop computers using common software programs. The purpose of our project was to determine the availability and cost of different types of data and how this data may benefit horticultural instruction. Satellite data currently is archived at NASA, NOAA, the Department of Defense, the US Geological Survey, and various meteorological departments throughout the world. Satellite data such as large-scale thermal imagery can be used to determine microclimate effects within urban areas, including the cooling effects of urban plants. Natural Density Vegetation Index (NDVI) imagery can indicate changes in vegetational cover or give general indications of plant health in large areas. NASA photographic imagery can show the effects of erosion on a large scale. Higher resolution imagery can give indications of plant stresses in large plantings such as orchards or vegetable plots.

Along with the seismic exploration extends to the mountain, the geological surface conditions of construction work area will become more and more complex, the construction will become very difficult. All of this requires the supervision department to detect construction observing system reasonable and the quality of construction at any time, in particular, the number of actual coverage can not be less than two-thirds of the design. For single survey line we can easily calculate the number of bin covering, but it related to the case of superimposed cover of different measuring line with the increase in the measuring line. On each bin element we have to traverse all of other measuring line in the work area database to determine whether there is overlap, so this operation is very time consuming. In this paper, we improved the search algorithm, at the same time the GPU parallel processing is introduced into the calculation. Because of the increased computational parallel, the time to generate the entire work area cover time’s image is shortened significantly.

Full textAbstract:
Although the Otway Basin is oriented west-north-westerly, and previously recognised major structural elements follow a similar trend, other structural trends have been found on recently obtained geophysical data.In 1989, an aeromagnetic and radiometric survey of the onshore Otway Basin was completed for the Victorian Department of Industry and the Bureau of Mineral Resources, Geology and Geophysics. This survey, together with a recent gravity compilation by the Geological Survey of Victoria, enables analysis of magnetic and gravity data trends reflecting basement and intra-basin structure.The trend analysis was carried out using modern image processing techniques including simulation of real-time sun-angles of the magnetic and gravity data, and composite images of the radiometric data, to highlight lineaments. This technology enables integration of magnetic, gravity, radiometric and, potentially, seismic, Landsat, topography and bathymetry data for basin structure analysis.The magnetic, gravity and radiometric trend analysis was compared to an earlier Landsat study (Baker, 1980) and a previous seismic data compilation of the Otway Basin (Megallaa, 1986).The present study has revealed the significance of major early Palaeozoic north-south and east-north-east to easterly trends. The latter trends have not previously been identified or discussed in earlier basin reviews. There appears to be a difference between trends reflected in the radiometric and seismic data and trends apparent in the gravity and magnetic data. This could indicate a change in principal stress directions during the evolution of the basin. The shape of the northern margin of the basin appears to be controlled by major north-easterly structures.

Full textAbstract:
Potentially toxic elements (PTEs) pose a threat to human health as they can easily enter human body via ingestion of polluted soil/sediment. In order to estimate bioavailability and access health impact on people, measurement of the oral bioaccessibility of a contaminant is crucial. Various laboratory based in vitro tests which mimic human gastrointestinal tract conditions can be used. In order to set up the method for analysing bioaccessibility of contaminants in soil samples in Laboratory for the analysis of geological materials at Department of Mineralogy, Petrology and Mineral resources (Faculty of Mining, Geology and Petroleum Engineering, University of Zagreb - RGNF), with regards to the available equipment, an orientation survey was carried out in collaboration with the Department of Biochemical Engineering (Faculty of Food Technology and Biotechnology, University of Zagreb - PBF). The digestion of two different samples in synthetic fluids (gastric and intestinal fluid) was performed simultaneously at RGNF laboratory and PBF laboratory under different extraction conditions according to each laboratory’s ability. Prior to analysis of bioaccessibility, detailed mineralogical and chemical characterization of samples was performed. The comparison of two experiments showed that there is a relatively good correlation between concentrations obtained after digestion of samples in different labs, under different conditions. As a result of this study, an efficient and relatively inexpensive method for determining the bioaccessibility was set up at Faculty of Mining, Geology and Petroleum Engineering, which makes this kind of tests more accessible and enables new approach in risk assessment studies.

"State Health Department Perceived Utility of and Satisfaction with ArboNET, the U.S. National Arboviral Surveillance System." Public Health Reports 127, no. 4 (July 2012): 383–90. http://dx.doi.org/10.1177/003335491212700406.

Objectives. We assessed the perceived utility of data collected through ArboNET, the national arboviral surveillance system, and evaluated state health department user satisfaction with system function. Methods. We used an online assessment tool to collect information about types of arboviral surveillance conducted, user satisfaction with ArboNET's performance, and use of data collected by the system. Representatives of all 53 reporting jurisdictions were asked to complete the assessment during spring 2009. Results. Representatives of 48 (91%) jurisdictions completed the assessment. Two-thirds of respondents were satisfied with ArboNET's overall performance. Most concerns were related to data transmission, particularly the lack of compatibility with the National Electronic Disease Surveillance System (NEDSS). Users found mosquito (85%), human disease (80%), viremic blood donor (79%), and veterinary disease (75%) surveillance data to be useful. While there was disagreement about the usefulness of avian mortality and sentinel animal surveillance, only 15% of users supported eliminating these categories. Respondents found weekly maps and tables posted on the U.S. Geological Survey (92%) and CDC (88%) websites to be the most useful reports generated from ArboNET data. Although many jurisdictions were willing to report additional clinical or laboratory data, time and resource constraints were considerations. Most respondents (71%) supported review and possible revision of the national case definition for human arboviral disease. Conclusions. As a result of this assessment, CDC and partner organizations have made ArboNET NEDSS-compatible and revised national case definitions for arboviral disease. Alternative data-sharing and reporting options are also being considered. Continued evaluation of ArboNET will help ensure that it continues to be a useful tool for national arboviral disease surveillance.
