Landfills are unpopular. They are dirty, smelly, environmentally unfriendly and potentially dangerous. Working with landfills is, perhaps, more unpopular. Being employed to expand the major landfill for a major city is a task that forces self-assessment, particularly when the land in question is pristine woodland with hiking and horse –riding trails. The understanding dawns when one focuses not on what is happening as a result of one’s work, but rather, what is not happening as a result of the work. Thousands of homes will be saved from polluted drinking water. The environment will not be severely affected and the area of influence of the landfill will not be so large. During my internship with Golder Associates, I had the opportunity to participate in the Site Investigation done to assess the technical viability of expanding a landfill. After an initial walkover, a grid was set up on the site, using machetes and chain saws. The forest was cleared on these lines by lumberjacks and the engineering team moved in to conduct a geophysical survey of the subsurface to assess the thickness of an underlying clay layer. That clay layer, if it is sufficiently thick, will protect the local water supply from escaped landfill leachate.

Geology of Greenland Survey Bulletin, 191, 133-143. https://doi.org/10.34194/ggub.v191.5141 _______________ Project Qaanaaq 2001, involving one season’s field work, was set up to investigate the mineral occurrences and potential of North-West Greenland between Olrik Fjord and Kap Alexander (77°10´N – 78°10´N; Fig. 1). Organised by the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, the project is mainly funded by the latter and has the overall goal of attracting the interest of the mining industry to the region. The investigated region – herein referred to as the Qaanaaq region – comprises 4300 km2 of ice-free land centred on Qaanaaq, the administrative capital of Qaanaap (Thule) municipality. Much of the region is characterised by a 500–800 m high plateau capped by local ice caps and intersected by fjords and glaciers. High dissected terrain occurs in Northumberland Ø and in the hinterland of Prudhoe Land where nunataks are common along the margin of the Inland Ice.

Enterprise Risk

Operational risk is defined as the potential losses resulting from events caused by inadequate or failed processes, people, equipment, and systems or from external events. One of the most important challenges for the management of the company is to improve its results through its operational risk identification and evaluation. Most of Enterprise Risk Management (ERM) scholarship has roots in the finance/risk management and insurance (RMI) discipline, mainly in the banking sector. This study proposes an innovative operational risk assessment methodology (OpRAM), to evaluate operational risks focused on telecommunications companies (TELCOs), on the basis of an operational risk self-assessment (OpRSA) process and method. The OpRSA process evaluates operational risks through a quantitative analysis of estimates which inputs are the economic impact and the probability of occurrence of events. The OpRSA method is the “engine” for calculating the economic risk impact, applying actuarial techniques, which allow estimation of unexpected losses and expected losses distributions in a TELCO. The results of the analyzed business unit in the field work were compared with standardized ratings (acceptable, manageable, critical, or catastrophic), and contrasted against the company’s managers, proving that the OpRSA framework is a reliable and useful management tool for the business, and leading to more research in other sectors where operational risk management is key for the company success.

The principle task of the sustainable development is the preservation of the genetic variety, which is similar challenge in the horticulture regarding the sublimation of fruit species. The breeders of the traditional fruit strains give stock to the sustenance diversity of the agro-environment on the species and landscape level. In 2009, hyperspectral images have been taken by AISA Dual sensors from the pear gene pool in Újfehértó, Hungary. The hyperspectral data cube (in the wavelength range of 400-2500 nm, with 1.5 m ground resolution) ensured possibility to make the spectral library of pear species. In the course of the simultaneously field work the spatial position and individual extent of all pear trees was defined to set up a detailed GIS data base. The water stress sensitivity of single species and the descriptive spectral curves were determined with common evaluation of the spectral and spatial data. Based on the unique methodology processing and the hyperspectral data base suitable strains can be chosen for agro-environment and let take adaptive stocks regarding climate change into the genetic grafting work. Furthermore we could determine and map the sparsely species in the region with the help of the hyperspectral data.

Ground Penetrating

Effective maintenance of railways requires a comprehensive assessment of the actual condition of the construction materials involved. In this regard, Ground-Penetrating Radar (GPR) stands as a viable alternative to the invasive and time-consuming traditional techniques for the inspection of these infrastructures. This work reports the experimental activities carried out on a test-site area within a railway depot in Rome, Italy. To this purpose, a 30 m-long railway section was divided into 10 sub-sections reproducing different various physical and structural conditions of the track-bed. In more detail, combinations of varying scenarios of fragmentation and fouling of the ballast were reproduced. The set-up was then investigated using different multi-frequency GPR horn antenna systems. The effects of the different physical conditions of ballast on the electromagnetic response of the material were analysed for each scenario using time- and frequency-domain signal processing techniques. Parallel to this, modelling was provided to estimate fouling content. Interpretation of results has proven the viability of the GPR method in detecting signs of decay at the network level, thereby proving this technique to be worthy of implementation in asset management systems.

After stressing the importance of the plant kingdom to Man and the dangers threatening the survival of an estimated 20,000 species of flowering plants, this paper presents details of the activities of the IUCN Threatened Plants Committee (TPC), set up by the Survival Service Commission in 1974. The Secretariat of the TPC works through three main approaches: (1) regional groups of botanists and other experts identifying threats to their floras, advising the TPC, and preparing recommendations; (2) specialist groups doing similar work for plant groups such as palms and cycads; and (3) institutional support of botanic gardens and similar organizations maintaining collections of threatened species in cultivation. This last aspect was launched at a conference on conservation held at Kew in 1975.The primary aim of the TPC is to gather and disseminate information on which species are threatened throughout the world. Accurate documentation is essential, and in this task both herbarium and field work are needed. Although our knowledge in general of temperate, subtropical, and islands, floras is reasonably good in most cases, and there are specialists working on most of such areas, our knowledge of continental tropical floras is much less comprehensive. There is an urgent need for check-lists to be rapidly compiled for such areas wherever possible. In tropical rain-forests, the difficulties encountered in listing threatened species are particularly acute.Provided present collaboration continues and finance is provided, initial lists of rare and threatened species will become available within the next decade for many areas. This information should be of great value in preventing needless extinction through lack of planning or forethought, in providing a valuable input in the selection of sites for reserves, etc., and in complementing habitat conservation approaches—as well as helping to stimulate action on individual species.The ‘Red Data’ categories used by IUCN to indicate the degrees of threat to individual species are outlined, and will be used in the three types of TPC publication—regional lists of rare and threatened species, bulletins on smaller areas with more detail on each species, and sheets for the Red Data Book which will give detailed case-histories of a limited selection of threatened species. All three approaches are under way; the European List has been completed, bulletins for many areas are on the way, and the TPC aims to start issuing new plant Red Data sheets in 1977–78.

The Golden Gate Highlands National Park (GGHNP) is well known for its impressive sandstone formations. While previous geoscience research in the park has focused on geology, palaeontology, slope forms and the prominent lichen weathering, remarkably little has been written on the diversity and possible origins of sandstone phenomena in the region. The objectives of this study were (1) to present a geomorphological map of prominent and interesting landforms for particular portions of the park and (2) to document the variety of macro- and microscale sandstone formations observed. During field work, we undertook global positioning system measurements to map landforms and, in addition, measured the dimensions of several landform types. A Schmidt hammer was used to conduct rock hardness tests at a variety of localities and lithologies for comparative purposes. We indentified and mapped 27 macro- and microscale sandstone landforms, of which 17 are described in detail. It is demonstrated that for the most part, the landforms are a likely product of surface lithological reactions to a regional climate characterised by pronounced multitemporal temperature and moisture shifts, recently and in the past. However, many of the geomorphological processes producing landforms are controlled by microclimates set up by factors such as macro- and microtopography. Conservation implications: The GGHNP is best known for its geological, geomorphological and palaeontological heritage. This paper highlights the diversity of sandstone geomorphological phenomena, many of them rare and ‘unique’ to the region. Not only are these landforms of aesthetic interest to tourists, but they also provide microhabitats for biota. Thus, conservation of biota requires associated conservation of geo-environments where they are established.

Alkali Aggregate Reactivity

Alkali-aggregate reactivity is a chemical reaction that occurs in some concrete structures. This reaction causes expansion and cracking of concrete. It may not be the main cause of premature deterioration; however, it is often the catalyst for other forms of deterioration. Since 1989, field work and laboratory testing for alkali-reactivity has been undertaken on selected aggregate, rock, and concrete core samples throughout Newfoundland. The field work and laboratory tests consisted of an assessment of the bedrock and aggregate sites to determine their quality and quantity for use as construction material; an examination of existing concrete structures to assess their durability with regard to alkali-aggregate reactivity. The site investigation of the concrete structures consisted of noting their date of construction, the rock and aggregate types used, the types of cracking, and the degree and type of deterioration of each structure. Results from laboratory testing, petrographic examination, and visual observation show that certain sedimentary, igneous, and metamorphic rock types may be potentially alkali-reactive, but the reaction may not always be deleterious to the concrete structure.Key words: alkali-aggregate reaction, concrete structures, laboratory tests, petrographic examination, rock types.

Distress Scale

The main aim of this study is to assess the level of distress among oncology patients a year and a half after the diagnosis of malignancy and completion of the combined oncology treatment (surgery, chemotherapy and/or radiotherapy). The second goal was to apply, for the first time in our country, the following world standards in the field of psycho-oncology set up by the National Comprehensive Cancer Network (NCCN) and the International Psycho-Oncology Society (IPOS) using a distress scale/distress thermometer on a sample of oncology patients who applied for psychological help and support in a private counseling center after completion of the oncological treatment. The examined sample consisted of 40 patients (30 women and 10 men) who, upon their first arrival at the counseling center and at the end of the initial psychological interview, were asked to fill the distress thermometer with the adequate explanations, provided that the self-assessment of the distress was significant to the further counseling psychological and/or psychotherapeutical treatment. The results of the whole sample showed that the highest percentage of patients examined (52.5%) evaluated various investigated problems as moderately stressful, 20% of patients assessed the problems as very stressful, 12.5% as slightly stressful and only 5% as not stressful. Related to practical problems, the largest percentage of patients assessed money and account payment issues (30%) and work - related issues (27.5%) as the most stressful. 22.5% of patients quote parenting and child care as the most stressful family problems. Concerning emotional problems, a significant percentage of patients (45%), quote concern and anxiety, 32.5% the existence of different fears, 22.5% sadness, and 20% irritability and tension as the most stressful emotional problems. 85% of patients stated that the fear of relapse of the disease is a problem that worries them the most. Patients in this study experience emotional problems considerably more stressful compared to other problems in the post-treatment period.

Headphone transfer function (HpTF) and head-related transfer function (HRTF) measurements are crucial in acoustic science and in binaural virtual acoustic applications. Yet, their measurement set-up, procedure or post-processing is different for nearly every lab, especially for the HRTF measurements. To compare findings between different labs, these measurement deviations have to be quantified alongside with their influence on perceptual aspects. In the scope of a cross-site investigation on loudness balancing between headphone and loudspeaker listening, a set of HpTFs with three different headphones (open, closed, insert earphones) and HRTF close to the eardrum were measured in 14 participants travelling to two different measurement sites at Aachen and Oldenburg. Though set-ups for measuring the HRTF are very different between sites, the gathered HRTFs are quite consistent across them. For the measured HpTFs, across sites the open headphones consistently yield a slightly lower variability in the range from 70 to 5000 Hz than the closed one while the insert earphones exhibit much higher variabilities and a limited range of reproducible results. The difference in loudness balancing across labs could well be predicted by site-specific systematic differences in HpTFs with the exception of 1 kHz narrowband stimulus. This clearly indicates the limits in comparability of HpTFs and loudness balancing across labs and the importance of using headphones with high repeatability like the open ones used in this investigation.

Chemical engineering unit operation labsdo an excellent job of integrating the whole curriculumand exposing students to pilot-scale systems. Where theyare often lacking, though, is the exposure to and use ofreal-life industrial automation by the future graduates. Aunit operation lab that has been automated usingindustrial level paradigms and equipment is the focus ofthis paper. A partnership with a global automationmanufacturer (Emerson) was established and the lab wasretrofitted using industrial sensors and actuators, aDistributed Control System (DeltaV DCS), industrialnetworks (FOUNDATION Fieldbus and AS-i), HumanMachine Interface (HMI) screens, and systemredundancy. The details of the automation along with itsuse through the lab curriculum will be discussed. Thiscross-curricular approach benefits students as, throughthe regular unit operation labs, they become familiar withkey elements of an automated set-up, understand the needfor it and its limitations, see control loops in action,communicate to the units through the HMI, and use theHMI to recover historical data on the processes. The labis a meso-scale of a processing facility and preparesstudents for field work after graduation. At the sametime, the traditional exposure to “manually operated”sensors and final elements is maintained as some of theunits have not been converted to fully automated systems
