    Full Text Available La Salmonella è un importante agente patogeno responsabile di zoonosi di notevole rilevanza economica. In Europa la salmonellosi è la seconda infezione trasmessa per via alimentare, in Italia il microrganismo continua ad essere la causa più frequente di infezione alimentare. In Europa sono in atto molti piani di sorveglianza di Salmonella in animali da allevamento, tuttavia il monitoraggio del microrganismo in animali selvatici è effettuato solo occasionalmente. Lo studio ha avuto l'obiettivo di indagare la presenza di Salmonella in animali selvatici e i ceppi antibiotico-resistenti. Nel periodo 2002-2010, 2.713 animali selvatici (Canidi, Mustelidi, Uccelli, Roditori e Ungulati, provenienti da aree dell'Italia nord-occidentale, sono stati testati per Salmonella mediante metodo microbiologico colturale seguito da tipizzazione sierologica e biochimica. Di questi, 117 (63 Canidi, 25 Mustelidi, 24 Uccelli, 5 Ungulati sono risultati positivi per Salmonella (4,3%. Sono stati isolati 130 ceppi appartenenti a diversi sierotipi e Salmonella Typhimurium è risultato quello più rappresentato. La sensibilità agli antibiotici è stata testata su 88 ceppi con test di disco-diffusione. La maggior parte dei ceppi analizzati (97,7% si sono mostrati intermedi (I o resistenti (R ad almeno una classe di antibiotici. I più alti valori sono stati osservati per la classe delle tetracicline. La presenza di sierotipi di Salmonella antibiotico-resistenti e responsabili di zoonosi è stata riscontrata in diverse specie di animali selvatici.

  4. Plutonium distribution and remobilization in sediments of the Rhone River mouth (North-Western Mediterranean); Distribution et remobilisation du plutonium dans les sediments du prodelta du Rhone (Mediterranee nord-occidentale)

    Energy Technology Data Exchange (ETDEWEB)

    Lansard, B

    2004-06-15

    The aim of the present study was to describe the distribution and remobilization of plutonium (Pu) in the sediments off the Rhone river mouth. Most of the {sup 238}Pu and {sup 239,240}Pu isotopes introduced into the Rhone River were discharged by the liquid effluents released from the Marcoule reprocessing plant, located 120 km upstream the river mouth. Due to its high affinity for particles and its long half life, {sup 238}Pu is a promising tracer to follow the dispersion of particulate matter from the Rhone River to the Mediterranean Sea. During the 3 REMORA cruises, sediment samples were specifically collected in the Rhone pro-delta area and more offshore on the whole continental shelf of the Gulf of Lions. The measurements of alpha emitters gave a first detailed spatial distribution of Pu isotope concentrations in surface sediments off the Rhone mouth. Using {sup 137}Cs concentrations and their correlations with Pu isotopes, we were able to give a first estimate of Pu inventories for the sediments of the study area. In 2001, plutonium inventories were estimated to 92 {+-} 7 GBq of {sup 238}Pu and 522 {+-} 44 GBq of {sup 239,240}Pu for an area of 500 km{sup 2} in front of the Rhone River mouth. Roughly, 50 % of these inventories are trapped in an area of 100 km{sup 2} corresponding to the extent of the Rhone pro-delta zone. In spring 2002, an ADCP, with current velocity and wave measurements, was moored off the Rhone River mouth. This unique in situ dataset highlights the major role of South-East swells in the erosion of pro-deltaic sediments and their dispersion to the South-Westward direction. Plutonium remobilization was examined using a new experimental design based on sediment resuspension processes studied within a linear recirculating flume. For Gulf of Lions sediments and for a given hydrodynamic stress, remobilization fluxes raised a maximum of 0.08 Bq.m{sup -2}.h{sup -1} for {sup 238}Pu and 0.64 Bq.m{sup -2}.h{sup -1} for {sup 239,240}Pu. A first plutonium budget determined for the study area indicates that at least 85 % of the Pu discharged over the 40 past years by the Marcoule reprocessing plant, are currently trapped in the sediments off the Rhone River mouth. Plutonium remobilization is potentially an important process but dispersion of contaminated sediments appeared to be limited in space. These results suggest a low exportation of particulate matter introduced by the Rhone River towards the continental shelf of the Gulf of Lions and the North-Western Mediterranean basin. (author)

    To follow the alluvial deposits from the Rhone in Mediterranean Sea, since the principle hydroelectric constructions (1960), it was necessary to find an adequate tracer. The plutonium isotopes have satisfied to the different characteristics. The specificity of the Rhone contribution is bound to the existence of the irradiated spent fuels reprocessing plant of Marcoule; the releases of this plant are characterized by the predominance of Plutonium 238. The results of this study show that the percentage of sediments coming from the Rhone in the recent contribution, is low beyond the pro delta: less than 5% of the sediment of the continental shelf concern the Rhone contribution. However, there are two zones for which the contribution is important and could play a role in the particulate transfer towards the high sea. (N.C.). 157 refs., 60 figs., 50 tabs.

    Mires in Germany are mainly used for agriculture. Peat mining is important regionally, but forest utilisation less so. Twenty years ago in the former West Germany, the first steps from peatland utilisation to peatland protection were taken. Bog protection programmes were developed first. Nowadays research directed to fen protection has begun, prompted by the decreasing importance of agriculture in Central Europe and an increasing environmental awareness. The situation regarding mire protection in Germany is presented for each Federal State individually. A rough estimate suggests 45 000 ha of protected bogs and 25 000 ha of protected fens. These areas include natural and semi-natural mires as well as rewetted mires. (30 refs.)

    The numerous application of coal with high content of humic substances are known. They are used in many branches of industry. The complex study of the composition of coal from upper Nitra mines has directed research to its application in the field of ecology and agriculture. The effective sorption layers of this coal and their humic acids can trap a broad spectrum of toxic harmful substances present in industrial wastes, particularly heavy metals. A major source of humic acids is coal - the most abundant and predominant product of plant residue coalification. All ranks of coal contain humic acids but lignite from Novaky deposit represents the most easily available and concentrated from of humic acids. The possibilities of utilisation of humic acids to remove heavy metals from waste waters was studied. The residual concentrations of the investigated metals in the aqueous phase were determined by AAs. From the results follows that the samples of coals humic acids can be used for the heavy metal removal from metal solutions and the real acid mine water. Oxidised coal with high content of humic acids and nitrogen is used in agriculture as fertilizer. Humic acids are active component in coal and can help to utilize almost quantitatively nitrogen in soil. The humic substances block and stabilize toxic metal residues already present in soil.

  19. Environmental assessment of incinerator residue utilisation

    In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. This thesis provides increased knowledge and proposes better approaches for environmental assessment of incinerator residue utilisation, particularly bottom ash from municipal solid waste incineration (MSWI). A life cycle assessment (LCA) based approach was outlined for environmental assessment of incinerator residue utilisation, in which leaching of trace elements as well as other emissions to air and water and the use of resources were regarded as constituting the potential environmental impact from the system studied. Case studies were performed for i) road construction with or without MSWI bottom ash, ii) three management scenarios for MSWI bottom ash and iii) three management scenarios for wood ash. Different types of potential environmental impact predominated in the activities of the system and the scenarios differed in use of resources and energy. Utilising MSWI bottom ash in road construction and recycling of wood ash on forest land saved more natural resources and energy than when these materials were managed according to the other scenarios investigated, including dumping in landfill. There is a potential for trace element leaching regardless of how the ash is managed. Trace element leaching, particularly of copper (Cu), was identified as being relatively important for environmental assessment of MSWI bottom ash utilisation. CuO is suggested as the most important type of Cu-containing mineral in weathered MSWI bottom ash, whereas in the leachate Cu is mainly present in complexes with dissolved organic matter (DOM). The hydrophilic components of the DOM were more important for Cu

  4. Substrate utilisation by plant-cell cultures

    Energy Technology Data Exchange (ETDEWEB)

    Fowler, M W

    1982-01-01

    Plant cell cultures have been grown on a wide range of carbon sources in addition to the traditional ones of sucrose and glucose. Biomass yields and growth rates vary greatly between the different carbon sources and there is a variation in response between different cell cultures to individual carbon sources. Some attempts have been made to grow cell cultures on 'waste' and related carbon sources, such as lactose, maltose, starch, molasses and milk whey. Only maltose was found to support growth to anything near the levels observed with glucose and sucrose. In the case of molasses carbon source cell growth was either non-existent or only just measurable. All the data point to glucose as being the most suitable carbon source, principally on the grounds of biomass yield and growth rate. It should be noted, however, that other carbon sources do appear to have a major (positive) influence on natural product synthesis. Uptake into the cell is an important aspect of carbohydrate utilisation. There is strong evidence that from disaccharides upwards, major degradation to smaller units occurs before uptake. In some cases the necessary enzymes appear to be excreted into the culture broth, in others they may be located within the cell wall; invertase that hydrolyses sucrose is a good example. Once the products of carbohydrate degradation and mobilisation enter the cell they may suffer one of two fates, oxidation or utilisation for biosynthesis. The precise split between these two varies depending on such factors as cell growth rate, cell size, nutrient broth composition and carbohydrate status of the cells. In general rapidly growing cells have a high rate of oxidation, whereas cells growing more slowly tend to be more directed towards biosynthesis. Carbohydrate utilisation is a key area of study, underpinning as it does both biomass yield and natural product synthesis. (Refs. 13).

  5. Utilising UDT to push the bandwidth envelope

    Science.gov (United States)

    Garrett, B.; Davies, B.

    eScience applications, in particular High Energy Physics, often involve large amounts of data and/or computing and often require secure resource sharing across organizational boundaries, and are thus not easily handled by today's networking infrastructures. By utilising the switched lightpath connections provided by the UKLight network it has been possible to research the use of alternate protocols for data transport. While the HEP projects make use of a number of middleware solutions for data storage and transport, they all rely on GridFTP for WAN transport. The GridFTP protocol runs over TCP as the layer 3 protocol by default, however with the latest released of the Globus toolkit it is possible to utilise alternate protocols at the layer 3 level. One of the alternatives is a reliable version of UDP called UDT. This report presents the results of the tests measuring the performance of single-threaded file transfers using GridFTP running over both TCP and the UDT protocol.

    Full Text Available In 2003 and 2004 was carried out the energy analysis of the different types of permanent grassland utilization on the Hrubý Jeseník locality. There were estimated values of the particular entrances of additional energy. Energy entrances moved according to the pratotechnologies from 2.17 GJ. ha–1 to 22.70 GJ.ha–1. The biggest share on energy entrances had fertilizers. It was 84.93% by the nitrogen fertilisation. The most energy benefit of brutto and nettoenergy was marked by the low intensive utilisation (33.40 GJ.ha–1 NEL and 32.40 GJ.ha–1 NEV on average. The highest value of energy efficiency (13.23% was marked by the low intensive utilization of permanent grassland. By using of higher doses of industrial fertilizers has energy efficiency decreased. From view of energy benefit and intensiveness on energy entrances it appears the most available utilisation of permanent grassland with three cuts per year (first cut on May 31st at the latest, every next after 60 days or two cuts per year (first cut on July 15th, next cuts after 90 days.

    The climate impact from the use of peat for energy production in Sweden has been evaluated in terms of contribution to atmospheric radiative forcing. This was done by attempting to answer the question 'What will be the climate impact if one would use 1 m{sup 2} of mire for peat extraction during 20 years?'. Two different methods of after-treatment were studied: afforestation and restoration of wetland. The climate impact from a peatland - wetland energy scenario and a peatland - forestry energy scenario was compared to the climate impact from coal, natural gas and forest residues. Sensitivity analyses were performed to evaluate which parameters that are important to take into consideration in order to minimize the climate impact from peat utilisation.

    1983-01-01

    Impetus for the development of new neutron detector designs has derived from the worldwide commissioning of neutron spallation sources. The design concepts, and principal methods of utilisation of these major installations, have been recently reviewed. Their principal feature of interest is their broadband neutron emission allowing neutron investigations of all types of structure in materials from biological molecules to steels. Conventional neutron detectors are gas-filled devices, based on BF/sub 3/ or /sup 3/He gas. Their major advantage is their intrinsically low background count. Their principal disadvantage is their slow response time (10-100 μs), high cost and relative lack of flexibility in design to cope with large areas or complex geometry detection. They are, however, long established and the research facilities around the world have a heavy investment in the interpretative hardware for gas detectors

    Wastes and dusts from steel industry, non-ferrous metallurgy and other branches can be utilised e.g. in agglomeration processes (sintering, pelletising or briquetting) and by injection into shaft furnaces. This paper deals with the second way. Combustion and reduction behaviour of iron- and carbon-rich metallurgical dusts and sludges containing lead, zinc and alkali as well as other wastes with and without pulverised coal (PC) has been studied when injecting into shaft furnaces. Following shaft furnaces have been examined: blast furnace, cupola furnace, OxiCup furnace and imperial-smelting furnace. Investigations have been done at laboratory and industrial scale. Some dusts and wastes under certain conditions can be not only reused but can also improve combustion efficiency at the tuyeres as well as furnace performance and productivity.

    The nuclear industry faces many challenges, notably to maximise safety, secure an adequate energy supply, manage wastes satisfactorily and achieve political acceptability. One way forward is to optimise together the various interdependent stages of the fuel cycle - the now familiar 'holistic approach'. Many of the issues will demand large R and D expenditure, most effectively met through international collaboration. Sustainable development requires optimum utilisation of energy potential, to which the most accessible key is recycling uranium and the plutonium bred from it. Realising anything like this full potential requires fast-neutron reactors, and therefore BNFL continues to sustain the UK involvement in their international development. Meanwhile, current R and D programmes must aim to make the nuclear option more competitive against fossil resources, while maintaining and developing the necessary skills for more advanced technologies The paper outlines the strategies being pursued and highlights BNFL 's programmes.

    Incineration ashes may be treated either as a waste to be dumped in landfill, or as a resource that is suitable for re-use. In order to choose the best management scenario, knowledge is needed on the potential environmental impact that may be expected, including not only local, but also regional and global impact. In this study, A life cycle assessment (LCA) based approach was outlined for environmental assessment of incinerator residue utilisation, in which leaching of trace elements as well as other emissions to air and water and the use of resources were regarded as constituting the potential environmental impact from the system studied. Case studies were performed for two selected ash types, bottom ash from municipal solid waste incineration (MSWI) and wood fly ash. The MSWI bottom ash was assumed to be suitable for road construction or as drainage material in landfill, whereas the wood fly ash was assumed to be suitable for road construction or as a nutrient resource to be recycled on forest land after biofuel harvesting. Different types of potential environmental impact predominated in the activities of the system and the use of natural resources and the trace element leaching were identified as being relatively important for the scenarios compared. The scenarios differed in use of resources and energy, whereas there is a potential for trace element leaching regardless of how the material is managed. Utilising MSWI bottom ash in road construction and recycling of wood ash on forest land saved more natural resources and energy than when these materials were managed according to the other scenarios investigated, including dumping in landfill.

    In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

    1. The objective of this study was to determine a metabolisable energy (ME) requirement model for broiler breeder hens. The influence of temperature on ME requirements for maintenance was determined in experiments conducted in three environmental rooms with temperatures kept constant at 13, 21 and 30 degrees C using a comparative slaughter technique. The energy requirements for weight gain were determined based upon body energy content and efficiency of energy utilisation for weight gain. The energy requirements for egg production were determined on the basis of egg energy content and efficiency of energy deposition in the eggs. 2. The following model was developed using these results: ME = kgW0.75(806.53-26.45T + 0.50T2) + 31.90G + 10.04EM, where kgW0.75 is body weight (kg) raised to the power 0.75, T is temperature ( degrees C), G is weight gain (g) and EM is egg mass (g). 3. A feeding trial was conducted using 400 Hubbard Hi-Yield broiler breeder hens and 40 Peterson males from 31 to 46 weeks of age in order to compare use of the model with a recommended feeding programme for this strain of bird. The application of the model in breeder hens provided good productive and reproductive performance and better results in feed and energy conversion than in hens fed according to strain recommendation. In conclusion, the model evaluated predicted an ME intake which matched breeder hens' requirements.

    The objectives of this study are to document the trend on utilisation of four or more (4 + ) antenatal care (ANC) over the last 22 years period and to explore the determinants and inequity of 4 + ANC utilisation as reported by the last two Bangladesh Demographic and Health surveys (BDHS) (2011 and 2014). The data related to ANC have been extracted from the BDHS data set which is available online as an open source. STATA 13 software was used for organising and analysing the data. The outcome variable considered for this study was utilisation of 4 + ANC. Trends of 4 + ANC were measured in percentage and predictors for 4 + ANC were measured through bivariate and multivariable analysis. The concentration index was estimated for assessing inequity in 4 + ANC utilisation. Utilisation of 4 + ANC has increased by about 26% between the year 1994 and 2014. Higher level of education, residing in urban region and richest wealth quintile were found to be significant predictors. The utilisation of 4 + ANC has decreased with increasing parity and maternal age. The inequity indices showed consistent inequities in 4 + ANC utilisation, and such inequities were increased between 2011 and 2014. In Bangladesh, the utilisation of any ANC rose steadily between 1994 and 2014, but progress in terms of 4 + ANC utilisation was much slower as the expectation was to achieve the national set target (50%: 4 + ANC utilisation) by 2016. Socio-economic inequities were observed in groups that failed to attend a 4 + ANC visit. Policymakers should pay special attention to increase the 4 + ANC coverage where this study can facilitate to identify the target groups whom need to be intervened on priority basis.

  1. SRUNs - sustainable resource utilisation networks for regions

    Niemetz, N.

    2015-01-01

    Nowadays it cannot be denied that fossil resources will approach or over-run their maximum global production rate within the 21st century. In addition to this resource constraints climate change has to be considered in parallel, requiring a drastic reduction in carbon emissions. These two trends clearly show that a fundamental shift is needed within the next decades, from fossil towards renewable resources. This transition gives rise to a change in the supply chains: while fossil fuels are typically exploited from point sources, nearly all renewable resources depend, either directly or indirectly, on solar radiation and area is required for their provision. This poses a new challenge for political, economic and social actors who can decide about land use. Within this thesis a conceptual framework of so called SRUNs – sustainable resource utilisation networks for regions - is developed. Regions have a responsibility in providing goods and services for the society within sustainable networks and bring the spatial dimension into consideration as well. The way how these networks are constructed is described in detail covering spatial planning, the stakeholder process, drivers and barriers as well as elements and features for SRUNs. Using the Process Network Synthesis (PNS) as an optimisation tool, the economic optimum of a network can be found and different scenarios compared. To show the ecological pressure of an established network an evaluation with the Sustainable Process Index (SPI) is carried out. Both computer tools are described and their application is shown in several case studies which are the versatility of the methods in practical implementation and application. Decision support tools offer the possibility for regional actors to analyse their region and to get a feeling about SRUNs. These tools provide an insight into the necessary changes which are needed to manage the shift towards a low carbon and sustainable society. (author) [de

    Objectives The aim of the present study was to assess comparative emergency department (ED) resource utilisation across age groups. Methods A retrospective analysis of data collected in the National Non-admitted Patient Emergency Department Care Database was undertaken to assess comparative ED resource utilisation across six age groups (0-14, 15-35, 36-64, 65-74, 75-84 and ≥85 years) with previously used surrogate markers of ED resource utilisation. Results Older people had significantly higher resource utilisation for their individual ED episodes of care than younger people, with the effect increasing with advancing age. Conclusion With ED care of older people demonstrated to be more resource intensive than care for younger people, the projected increase in older person presentations anticipated with population aging will have a magnified effect on ED services. These predicted changes in demand for ED care will only be able to be optimally managed if Australian health policy, ED funding instruments and ED models of care are adjusted to take into account the specific care and resource needs of older people. What is known about the topic? Current Australian ED funding models do not adjust for patient age. Several regional studies have suggested higher resource utilisation of ED patients aged ≥65 years. Anticipated rapid population aging mandates that contribution of age to ED visit resource utilisation be further explored. What does this paper add? The present study of national Australian ED presentations compared ED resource utilisation across age groups using surrogate markers of ED cost. Older people were found to have significantly higher resource utilisation in the ED, with the effect increasing further with advancing age. What are the implications for practitioners? The higher resource utilisation of older people in the ED warrants a review of current ED funding models to ensure that they will continue to meet the needs of an aging population.

    operation. The market is expected to move forward but the available public information is very limited, especially concerning the technologies used and volumes produced. Woody feedstocks will be the main raw material source. The utilisation rate of forest industry residues and by-products is relatively high in the EU and wood supply in Central Europe remains more or less stable, hence the price of the raw material is at a fairly high level. The utilities' capability to pay for the product depends mainly on the national feed-in tariffs of green electricity. The energy price for the user is at least twice as high as that of coal. (orig.)

    Complete text of publication follows. In the cooperation between KITE Ltd., Nadudvar, Hungary and the Hertelendi Laboratory of Environmental Studies, the aim was to determine the ideal locations of fertilising, the ideal distance of rows for the ideal production yield. To track the nitrogen utilisation of maize (Zea mays) 15 N enriched NH 4 NO 3 fertiliser was introduced among the usual fertilisers in the maize field of KITE Ltd. Nadudvar, Hungary on 30 th March 2012, before sowing. Four maize samples were taken from different areas of different fertiliser treatment (non-fertilised and non-labelled, fertilised and non-labelled, fertilised and labelled between the rows and fertilised and labelled within the rows) and from different development stages of the plant on 22 nd May, 8 th June, 6 th July and 7 th September being sampling periods 1-4, respectively. The plant samples were subsampled based on organs: root, stem and leaf. Samples were dried to constant mass and pulverised. The 15 N measurements were made by a Thermo Finnigan Delta PLUS XP isotope ratio mass spectrometer coupled with an elemental analyser. In case of non-fertilised and non-labelled plants, all the three organs were getting 15 N depleted with time, most intensively the stem and the less intensively the root (Figure 1). For the leaves and stems of the fertilised and non-labelled plants, the tendency in time is very similar to the ones of the non-fertilised and non-labelled plants, however, the roots of the fertilised and non-labelled plants got significantly enriched in the sample of September. In case of the fertilised and labelled between-the-rows samples, labelling is slightly seen as the delta values are positive. These values are significantly lower than the ones for the fertilised and labelled-within-the-rows plants. It is seen that fertiliser got to the vegetation in the largest extent in this layout. Labelling showed its maximum intensity in the second sampling (8 th June) showing that

    Australia, England, France and New Zealand use different policies to regulate their medicines market, which can impact on utilisation and price. To compare the prices and utilisation of statins in Australia, England, France and New Zealand from 2011 to 2013. Utilisation of statins in the four countries was compared using Defined Daily Doses (DDD) per 1000 inhabitants per year. Pairwise Laspeyres and Paasche index comparisons were conducted comparing the price and utilisation of statins. The results showed that the price of statins in New Zealand was the cheapest. The price of statins in Australia was most expensive in 2011 and 2012 but France was more expensive in 2013. There were large differences between the Laspeyres index and Paasche index when comparing the price and utilisation of England with Australia and France. The policies that regulate the New Zealand and England medicines markets were more effective in reducing the price of expensive statins. The relative utilisation of cheaper statins was greatest in England and had a large effect on the differences between the two index results. The pricing policies in Australia have been only partly effective in reducing the price of statins compared to other countries.

  10. Jarosite characteristics and its utilisation potentials

    During metallic zinc extraction from zinc sulphide or sulphide ore, huge quantity of jarosite is being released universally as solid residues. The jarosite mainly contains iron, sulphur, zinc, calcium, lead, cadmium and aluminium. Jarosite released from such industrial process is complex and its quality and quantity make the task more complex for safe disposal. Apart from water contamination, jarosite already accumulated and its increasing annual production is a major source of pollution for surrounding environment including soil, vegetation and aquatic life and hence its disposal leads to major concern because of the stringent environmental protection regulations. An attempt was made to evaluate the characteristics of Indian jarosite with an objectives to understand its potentials for recycling and utilising as raw materials for developing value added products. Sand and Coal Combustion Residues (CCRs) was used as an admixture to attain good workability and detoxify the toxic substance in the jarosite. Result revealed that jarosite is silty clay loam in texture having 63.48% silt sized and 32.35% clay sized particles. The particle size of jarosite (D 9 = 16.21 ± 0.20 μm) is finer than the CCRs (D 9 = 19.72 ± 0.18 μm). The jarosite is nonuniform in structure and shape as compared to the CCRs having spherical, hollow shaped and some of them are cenosphere in nature. The major mineral phase of jarosite is Potassium Iron Sulphate Hydroxide {KFe 3 (SO 4 ) 2 (OH) 6 }and Iron Sulphate Hydrate {2Fe 2 O 3 SO 3 .5H 2 O}. In CCRs the dominant phases are quartz {SiO 2 }, mullite {3Al 2 O 3 .2SiO 2 } and hematite {Fe 2 O 3 }. The high electrical conductivity of jarosite (13.26 ± 0.437 dS/m) indicates that the presence of cations and anions are predominant over CCRs (0.498 ± 0.007 dS/m). The major portion of jarosite consists of iron (23.66 ± 0.18%), sulphur (12.23 ± 0.2%) and zinc (8.243 ± 0.075%). But CCRs main constituents are silicon ( 27.41 ± 0.74%), aluminium (15

    Full Text Available Four aspects of effective glass melting have been defined – namely the fast kinetics of partial melting phenomena, a consideration of the melting phenomena ordering, high utilisation of the melting space, and effective utilisation of the supplied energy. The relations were defined for the specific melting performance and specific energy consumption of the glass melting process which involve the four mentioned aspects of the process and indicate the potentials of effective melting. The quantity “space utilisation” has been treated in more detail as an aspect not considered in practice till this time. The space utilisation was quantitatively defined and its values have been determined for the industrial melting facility by mathematical modelling. The definitions of the specific melting performance and specific energy consumption have been used for assessment of the potential impact of a controlled melt flow and high space utilisation on the melting process efficiency on the industrial scale. The results have shown that even the partial control of the melt flow, leading to the partial increase of the space utilisation, may considerably increase the melting performance, whereas a decrease of the specific energy consumption was determined to be between 10 - 15 %.

    The uptake and utilisation of phosphate from different jute growing soils of West Bengal viz., Humaipur (24-Parganas), Haripal (Hooghly), Panagarh (Burdwan) and the Jute Agricultural Research Institute, Barrackpore (24-Parganas) were studied in pot under fertilizer combination of NP, PK and NPK. The soils from 24-Parganas district behaved in a similar manner with respect to dry matter yield, fertilizer P uptake and per cent utilisation of added P. The P deficient between the two, Humaipur soil, showed comparatively higher P utilisation. Other two soils, Haripal and Panagarh, though of different origin behaved similarly, highest soil P has been contributed by the P rich soil (J.A.R.I.) to the crop, though it showed minimum P fixation.

    Full Text Available Tangier is the main city of the Northern Moroccan region. As the only one to benefit from the International Status during the French Protectorate, it has always been influenced by multilingualism: the local diglossia, due to the coexistence of the locale dialect, darija, and Standard Arabic, exists side by side with three local darijas of Amazight, official language from 2011; more, due to the colonial period, the general knowledge of Spanish is linked to the territorial control of Spain on the North of Morocco and to the commercial contacts between the shores while French was imposed as official language in the educational and administrative sphere. The identity of translational city (S. Simon, 2012 still exists and it is today still problematized because of the increasing migration flows directed to the cities and originating both in Europe and in the Moroccan countryside. This phenomenon is the result of the unprecedented economical development of the North, due to the set up of de-localized productive activities in free zones spread over the whole territory. The categories of class and gender determine a relation with the languages beginning from situated subjects and reveal the differential inclusion produced in loco. Starting from some interviews to women working in the de-localized textile factories of Tangier, I propose a socio-linguistics analysis aimed to identify some translation processes among situated female universes.

    B. Wilhelm

    2008-01-01

    Full Text Available During the recent years, multiple studies demonstrated that C-peptide is not an inert peptide, but exerts important physiological effects. C-peptide binds to cell membranes, stimulates the Na,K-ATPase and the endothelial nitric oxide (NO synthase. Moreover, there is evidence that C-peptide decreases glomerular hyperfiltration and increases glucose utilisation. Nevertheless, there is still limited knowledge concerning mechanisms leading to an increased glucose utilisation either in rats or in humans. The aim of this paper is to give an overview over the published studies regarding C-peptide and glucose metabolism from in vitro studies to longer lasting studies in humans.

  6. Optimal environmental benefits of utilising alternative energy technologies in Jordan

    International Nuclear Information System (INIS)

    Mrayyan, B.

    2004-01-01

    With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and economical constraints that hinder the import of crude oil from neighbouring countries and of the fact that Jordan has limited fossil fuel resources, strategies to meet energy demand are being addressed and examined together with their consequences and the ways in which they could be utilised. This paper assesses for the first time, the potential of using alternative energy technologies in Jordan, including the utilisation of solar energy for water heating, for wind towers in rural areas and also for biogas production from waste. Approximately 2% of unconventional renewable energy resources are being utilised. The data and scenarios of this study were presented in a manner that would assist decision makers, funding agencies, researchers and other related parties to establish programmes that will be helpful in meeting the energy demand, while preserving the environment and maintaining sustainability.

    2008-01-01

    The goals and frameworks for traffic and transport policy for the Netherlands to 2020 are described in the Mobility Document. Whereas government policy previously viewed mobility as a problem or as something permissible, the assumption is now that mobility is a must. Mobility, for people as well as goods, is a prerequisite for society and the economy to function well. The Mobility Document contains ambitious goals to deal with current and anticipated traffic and transport problems: door to door, faster, cleaner and safer. Three interrelated pillars are to help achieve these goals: Building, Pricing and Utilisation. Work is being done on the Building and Pricing pillars; Utilisation is elaborated further in this policy framework. The Policy Framework for Utilisation is an elaboration of the Mobility Document for the 2008-2020 period and aims for faster, cleaner, safer travel from door to door. The purpose of this policy framework is to describe the direction of development of utilisation, in terms of content as well as process, to indicate actions that are required and to provide perspective on the expected effects. The policy framework is in line with current developments or plans, caters to new opportunities (technological and otherwise), encourages the innovative potential of the market and provides room for joint ventures between the government and the market. It will result in actions for the short term and provide direction for activities and developments for the longer term

    Sequestration and degranulation of leucocytes in the pulmonary microcirculation is considered to be a key event in the development of acute respiratory distress syndrome in patients with sepsis. Glucose serves as the main source of energy in activated leucocytes. The aim of this study was to assess whether glucose utilisation in the lungs can be used as an indicator of pulmonary leucocyte accumulation in an experimental model of sepsis of intra-abdominal origin. Sepsis was induced in rats by abdominal implantation of a gelatine capsule containing bacteria and rat colonic contents. Empty gelatine capsules were implanted in control animals. Animals were studied 6 and 12 h after sepsis induction. Glucose utilisation was measured as the tissue uptake of fluorine-18-fluorodeoxyglucose ( 18 FDG) 1 h after intravenous injection of the tracer. Micro-autoradiography was also performed after injection of tritiated deoxyglucose. We found increased uptake of 18 FDG in the lungs of septic animals. The uptake also increased with time after sepsis induction. 18 FDG uptake in circulating leucocytes was increased in septic animals compared with controls, and micro-autoradiography showed intense accumulation of deoxyglucose in leucocytes in the lungs of septic animals. We conclude that glucose utilisation is increased in the lungs of septic rats. Measurements of pulmonary glucose utilisation as an index of leucocyte metabolic activity may open new possibilities for studies of the pathophysiology of sepsis and for evaluation of therapeutic interventions.

Compte tenu de la date des essais thermonucleaires, des courants atmospheriques et de la saison locale des pluies, on peut conclure qu'il n'y a aucun transport tropospherique direct de tritium provenant de la zone des essais vers la region consideree. Les concentrations de tritium mesurees sont dues au passage de tritium des hautes altitudes dans les couches atmospheriques inferieures. On a evalue la duree moyenne du sejour dans l'atmosphere du tritium stratospherique provenant de diverses sources. Les constatations faites semblent prouver que le tritium ne se melange que lentement aux masses d'air de la stratosphere. Les differences constantes entre les concentrations de tritium a divers endroits sont expliquees en tenant compte des differentes situations qui sont a l'origine des pluies. On montre que le melange des masses d'air maritimes et continentales a une influence primordiale sur la teneur en tritium des eaux de pluie et que l'etendue de la mer Mediterranee est faible par rapport a l'ampleur des phenomenes meteorologiques en jeu.

    The paper presents the prospects for agricultural utilisation of the sludge produced from wastewater treatment plants in Greece and more specifically focuses on a critical review of the legislatory framework, determination of the quantitative and qualitative characteristics of the produced sludges, examination of possible sludge treatment methods and evaluation of the possibilities and prospects of sludge utilisation on the basis of the above considerations. Landfilling is practically the only route to sludge disposal in Greece. However, in view of the anticipated future restrictions for landfilling within the European Union, this method is clearly a short-term solution and alternative options, including agricultural reuse, must be implemented. The results of a recent survey are presented and discussed in relation to this need.

  5. Reducing Risky Security Behaviours: Utilising Affective Feedback to Educate Users

    2014-11-01

    Full Text Available Despite the number of tools created to help end-users reduce risky security behaviours, users are still falling victim to online attacks. This paper proposes a browser extension utilising affective feedback to provide warnings on detection of risky behaviour. The paper provides an overview of behaviour considered to be risky, explaining potential threats users may face online. Existing tools developed to reduce risky security behaviours in end-users have been compared, discussing the success rates of various methodologies. Ongoing research is described which attempts to educate users regarding the risks and consequences of poor security behaviour by providing the appropriate feedback on the automatic recognition of risky behaviour. The paper concludes that a solution utilising a browser extension is a suitable method of monitoring potentially risky security behaviour. Ultimately, future work seeks to implement an affective feedback mechanism within the browser extension with the aim of improving security awareness.

  11. The Utilisation of Music by Casino Managers: An Interview Study.

    Bramley, Stephanie; Dibben, Nicola; Rowe, Richard

    2016-12-01

    Music is ubiquitous in retail and commercial environments, with some managers believing that music can enhance the customer experience, increase footfall and sales and improve consumer satisfaction. Casino gambling is popular in the United Kingdom and anecdotal evidence suggests that music is often present. However, little is known about the rationale for music use from the perspective of casino managers. In this study semi-structured interviews were conducted with five casino managers to establish their motivations for utilising music, the factors informing their choice of music and the extent to which music is used with the intention of influencing gambling behaviour. Results showed that casino managers utilised two types of music-recorded background music, often sourced via external music supply companies and live music. Live music was often situated away from the gaming floor and used primarily to accompany participation in non-gambling activities. Recorded background music was not used with the direct aim of influencing customers' gambling behaviour, but to create the right atmosphere for gambling and to promote certain moods within the casinos. To achieve these aims casino managers manipulated the tempo, volume and genre of the recorded background music. Casino managers also reported that some gamblers listen to music via portable music players, possibly with the intention of customising their gambling experience. This study is unique as it has provided a first-hand account of casino managers' implicit theories with regards to why they utilise music and the roles which music is considered to fulfil in casinos.

  12. Barriers to research utilisation among forensic mental health nurses.

    Carrion, Maria; Woods, Phil; Norman, Ian

    2004-08-01

    This study used a cross-sectional, descriptive design to identify barriers to research utilisation among forensic mental health nurses. A postal questionnaire was sent to the total population of 88 registered nurses working in a forensic mental health hospital in the UK. Forty-seven responded representing a response rate of 53%. Results showed that the greatest barriers to research utilisation were those related to the characteristics of the setting in which nurses work or the personal characteristics of nurses themselves, which seems to be consistent with previous studies undertaken in the area. However, the nurses reported it especially difficult to trust what research shows because they feel that it is not always possible to apply those findings to their particular work environment. The main implications for policy are a need for an increase in support from management, programmes of advanced education to provide nurses with research skills, an improvement in accessibility and availability of research reports and an increase in time available to read and implement research. The main suggestions for future research are that qualitative studies should be carried out to attain a better understanding of mental health nurses' attitudes towards research utilisation.

    2017-11-01

    Geothermal energy is considered as a strategic and sustainable source of renewable energy that can be effectively managed in several economic sectors. In Poland, despite the abundant potential of such resources, its share in the energy mix of renewable energy sources remains insubstantial. The utilisation of geothermal resources in Poland is related to the hydrogeothermal resources, however, numerous researches related to petrogeothermal energy resources are being performed. The utilisation of each type of energy, including geothermal, has an impact on the natural environment. In case of the effective development of geothermal energy resources, many environmental benefits are pointed out. The primary one is the extraction of clean, green energy that is characterised by the zero-emission rate of pollutants into the atmosphere, what considering the current environmental pollution in many Polish cities remains the extremely important issue. On the other hand, the utilisation of geothermal energy might influence the natural environment negatively. Beginning from the phase of drilling, which strongly interferes with the local landscape or acoustic climate, to the stage of energy exploitation. It should be noted that the efficient and sustainable use of geothermal energy resources is closely linked with the current law regulations at national and European level.

  14. Life cycle assessment of peat utilisation in Finland

    International Nuclear Information System (INIS)

    Maelkki, H.

    1997-01-01

    Environmental issues related to the production of peat and its use in energy generation have been the subject of public debate and research over the past few years in Finland. Peat is both an indigenous and a locally utilised fuel. Finland has no fossil fuel resources, and the transportation distances of imported fuels into Finland are normally long. In Finland the large peat resources can be utilised locally and peat-burning power plants are situated near the peatlands. Peat production and energy conversion methods are being continuously developed to make use of the environmentally and technically best available technology. In Finland peat formation exceeds peat utilisation and an increase in peat utilisation is therefore sustainable. The life cycle assessment concept gives an opportunity to evaluate and improve the environmental quality of peat utilisation options. The study focuses on an inventory analysis, but some of the most common methods of impact assessment with valuation are also included. The study also includes a comparison of fossil fuels and a discussion part. All the calculated results are based on net emissions. The background emissions of natural peatland are subtracted from the emissions of the utilisation phases. Milled peat and sod peat are reported in this study. Horticultural peat is studied simultaneously, but it will be reported later. The Sod Wave, Haku and Tehoturve methods are studied for the production of peat. The power plants of the study are Kempele heating plant and Rauhalahti cogeneration plant. The functional unit is 1 MWh produced total energy. The temporal boundaries vary from 112 to 128 years, depending on the peat production methods used. The restoration time is 100 years in all options. The emissions of greenhouse gases are based on the reports of The Finnish Research Programme on Climate Change. The water emissions are based on control monitoring reports from 1994 and 1995. The water emissions of the restoration phase are

  15. An analysis of partial efficiencies of energy utilisation of different macronutrients by barramundi (Lates calcarifer) shows that starch restricts protein utilisation in carnivorous fish.

    2017-02-01

    This study examined the effect of including different dietary proportions of starch, protein and lipid, in diets balanced for digestible energy, on the utilisation efficiencies of dietary energy by barramundi (Lates calcarifer). Each diet was fed at one of three ration levels (satiety, 80 % of initial satiety and 60 % of initial satiety) for a 42-d period. Fish performance measures (weight gain, feed intake and feed conversion ratio) were all affected by dietary energy source. The efficiency of energy utilisation was significantly reduced in fish fed the starch diet relative to the other diets, but there were no significant effects between the other macronutrients. This reduction in efficiency of utilisation was derived from a multifactorial change in both protein and lipid utilisation. The rate of protein utilisation deteriorated as the amount of starch included in the diet increased. Lipid utilisation was most dramatically affected by inclusion levels of lipid in the diet, with diets low in lipid producing component lipid utilisation rates well above 1·3, which indicates substantial lipid synthesis from other energy sources. However, the energetic cost of lipid gain was as low as 0·65 kJ per kJ of lipid deposited, indicating that barramundi very efficiently store energy in the form of lipid, particularly from dietary starch energy. This study defines how the utilisation efficiency of dietary digestible energy by barramundi is influenced by the macronutrient source providing that energy, and that the inclusion of starch causes problems with protein utilisation in this species.

  16. Fish utilisation of wetland nurseries with complex hydrological connectivity.

    Directory of Open Access Journals (Sweden)

    Ben Davis

    Full Text Available The physical and faunal characteristics of coastal wetlands are driven by dynamics of hydrological connectivity to adjacent habitats. Wetlands on estuary floodplains are particularly dynamic, driven by a complex interplay of tidal marine connections and seasonal freshwater flooding, often with unknown consequences for fish using these habitats. To understand the patterns and subsequent processes driving fish assemblage structure in such wetlands, we examined the nature and diversity of temporal utilisation patterns at a species or genus level over three annual cycles in a tropical Australian estuarine wetland system. Four general patterns of utilisation were apparent based on CPUE and size-structure dynamics: (i classic nursery utlisation (use by recently settled recruits for their first year (ii interrupted peristence (iii delayed recruitment (iv facultative wetland residence. Despite the small self-recruiting 'facultative wetland resident' group, wetland occupancy seems largely driven by connectivity to the subtidal estuary channel. Variable connection regimes (i.e. frequency and timing of connections within and between different wetland units (e.g. individual pools, lagoons, swamps will therefore interact with the diversity of species recruitment schedules to generate variable wetland assemblages in time and space. In addition, the assemblage structure is heavily modified by freshwater flow, through simultaneously curtailing persistence of the 'interrupted persistence' group, establishing connectivity for freshwater spawned members of both the 'facultative wetland resident' and 'delayed recruitment group', and apparently mediating use of intermediate nursery habitats for marine-spawned members of the 'delayed recruitment' group. The diversity of utilisation pattern and the complexity of associated drivers means assemblage compositions, and therefore ecosystem functioning, is likely to vary among years depending on variations in hydrological

    Red mud is a high volume industrial waste, and its management poses a unique challenge. For the utilisation of red mud, an economical, energy saving, environmental friendly and widely applicable method has been found. The proposed novel method is purely chemical, and achieves the recovery of all the oxides contained in red mud totally and transforms them into high value added products. The present work shows that an investment in an industrial plant, treating red mud and turning a toxic industrial waste in commercial products, is safe and viable. © The Author(s) 2015.

    Using political ecology as its conceptual framework, this paper focuses on the changes in forest utilisation and management of South Kyrgyzstan's walnut-fruit forests over the last century. The aim of this study on human-environment interactions is to investigate the relationship between actors on the one side, their interests and demands, and the forests and forested lands on the other. Forest resource utilisation and management - and even the recognition of different forest products as resources - are connected with political and socio-economic conditions that change with time. The walnut-fruit forests of South Kyrgyzstan are unique, characterised by high biodiversity and a multiplicity of usable products; and they have been utilised for a long time. Centralised and formal management of the forests started with the Russian occupation and was strengthened under Soviet rule, when the region became a part of the USSR. During this era, a state forest administration that was structured from Moscow all the way down to the local level drew up detailed plans and developed procedures for utilising the different forest products. Since the collapse of the Soviet Union, the socio-political and economic frame conditions have changed significantly, which has brought not only the sweeping changes in the managing institutions, but also the access rights and interests in the forest resources. At present, the region is suffering from a high unemployment rate, which has resulted in the forests' gaining considerable importance in the livelihood strategies of the local population. Political and economic liberalization, increased communication and trans-regional exchange relations have opened the door for international companies and agents interested in the valuable forest products. Today, walnut wood and burls, walnuts, wild apples and mushrooms are all exported to various countries in the world. Scientists and members of various international organisations stress the ecological

    A heating unit utilising the decay heat from irradiated material comprises a storage envelope for the material associated with a heat exchange system, means for producing a flow of air over the heat exchange system to extract heat from the material, an exhaust duct capable of discharging the heated air to the atmosphere, and means for selectively diverting at least some of the heated air to effect the required heating. With the flow of air over the heat exchange system taking place by a natural thermosyphon process the arrangement is self regulating and inherently reliable. (author)

    The study was conducted to assess how the general public in the Klang Valley, Malaysia, utilised community pharmacists. This was a prospective observational study which documented interactions between community pharmacists and their customers. A researcher was stationed in 10 participating community pharmacies around the Klang Valley to observe and record all the interactions, using a structured data-collection form. KEYS FINDINGS: Interactions between 1914 customers and the pharmacists of the 10 community pharmacies were recorded. A total of 2199 requests were made by these customers. The main types of request were for medications by brand name (32.2%), advice on minor health problems (25.9%) and for health supplements (11.7%). Only 65 prescriptions were received by the community pharmacies; that is, fewer than two prescriptions per pharmacy per day. The pharmacists provided counselling for only 54.4% of the requests where a medication or health supplement was dispensed. Counselling by pharmacist was significantly associated with the type of request (P Malaysia was to purchase a particular medication. Few prescriptions were filled at community pharmacies in Malaysia, indicating the under-utilisation of community pharmacists as a safety net for prescribed medications in primary care. © 2012 The Authors.

    Full Text Available Logistics operations are energy-consuming and impact the environment negatively. Improving energy efficiency in logistics is crucial for environmental sustainability and can be achieved by increasing the utilisation of capacity. This paper takes an interactive approach to capacity utilisation, to contribute to sustainable freight transport and logistics, by identifying its causes and mitigations. From literature, a conceptual framework was developed to highlight different system levels in the logistics system, in which the energy efficiency improvement potential can be found and that are summarised in the categories activities, actors, and areas. Through semi-structured interviews with representatives of nine companies, empirical data was collected to validate the framework of the causes of the unutilised capacity and proposed mitigations. The results suggest that activities, such as inflexibilities and limited information sharing as well as actors’ over-delivery of logistics services, incorrect price setting, and sales campaigns can cause unutilised capacity, and that problem areas include i.a. poor integration of reversed logistics and the last mile. The paper contributes by categorising causes of unutilised capacity and linking them to mitigations in a framework, providing a critical view towards fill rates, highlighting the need for a standardised approach to measure environmental impact that enables comparison between companies and underlining that costs are not an appropriate indicator for measuring environmental impact.

    Full Text Available Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of 0.5. The concrete were cured for 1, 2, 3, 7, 14 and 28 days. The properties of the concrete such as workability, durability, density, compressive strength and indirect tensile strength were tested. A controlled mix of concrete was also prepared in similar way using conventional materials and the results were compared with the tailings concrete. It was found that the iron ore tailings may be utilised for complete replacement for conventional aggregates in concrete. The iron ore tailings aggregates concrete exhibited a good mechanical strength and even in the case of compressive strength, there was an improvement of 11.56% over conventional aggregates concrete. The indirect tensile strength did not improve against the control mix due high content of fines in the tailings aggregates but showed 4.8% improvement compared with the previous study where the conventional fine aggregates was partially replaced by 20% with iron ore tailings.

    Sewage sludge combustion - either in an incinerator or for heat or power generation - has always been important and is getting ever more so. From the cost aspect, it makes quite a difference whether sewage sludge is just incinerated or utilised. The author makes it clear that this cost aspect - and what it means to communities and citizens - tends to be neglected by those who favour sewage sludge combustion and utilisation. [German] Die Verbrennung von Klaerschlamm - sei es als Schlammveraschung oder als thermische oder energetische Verwertung - hat schon immer fuer grosse Klaeranlagen einen bedeutenden Stellenwert gehabt. Die Bedeutung der Verbrennung scheint in letzter Zeit sogar zuzunehmen. Unter Kostengesichtspunkten ist es ein grosser Unterschied, ob ein Klaerschlamm nur verascht oder energetisch verwertet wird. Vor dem Hintergrund der allgemeinen Diskussion um die leeren Kassen der Kommunen, um die sogenannte dritte Miete fuer den Buerger und damit die Zumutbarkeit fuer weitere Steigerungen der Abwassergebuehren stoert mich die Bagatellisierung der Kostengesichtspunkte vor allem auf Seiten derer, die die Verbrennung der Klaerschlaemme fordern.

    Galindo Cifre, P.; Badr, O.

    2007-01-01

    Electrolytic hydrogen production is an efficient way of storing renewable energy generated electricity and securing the contribution of renewables in the future electricity supply. The use of this hydrogen for the production of methanol results in a liquid fuel that can be utilised directly with minor changes in the existing infrastructure. To utilise the renewable generated hydrogen for production of renewable methanol, a sustainable carbon source is needed. This carbon can be provided by biomass or CO 2 in the flue gases of fossil fuel-fired power stations, cement factories, fermentation processes and water purification plants. Methanol production pathways via biomass gasification and CO 2 recovery from the flue gasses of a fossil fuel-fired power station have been reviewed in this study. The cost of methanol production from biomass was found to lie in the range of 300-400 EUR/tonne of methanol, and the production cost of CO 2 based methanol was between 500 and 600 EUR/tonne. Despite the higher production costs compared with methanol produced by conventional natural gas reforming (i.e. 100-200 EUR/tonne, aided by the low current price of natural gas), these new processes incorporate environmentally beneficial aspects that have to be taken into account.

    Hendra virus causes sporadic fatal disease in horses and humans in eastern Australia. Pteropid bats (flying-foxes) are the natural host of the virus. The mode of flying-fox to horse transmission remains unclear, but oro-nasal contact with flying-fox urine, faeces or saliva is the most plausible. We used GPS data logger technology to explore the landscape utilisation of black flying-foxes and horses to gain new insight into equine exposure risk. Flying-fox foraging was repetitious, with individuals returning night after night to the same location. There was a preference for fragmented arboreal landscape and non-native plant species, resulting in increased flying-fox activity around rural infrastructure. Our preliminary equine data logger study identified significant variation between diurnal and nocturnal grazing behaviour that, combined with the observed flying-fox foraging behaviour, could contribute to Hendra virus exposure risk. While we found no significant risk-exposing difference in individual horse movement behaviour in this study, the prospect warrants further investigation, as does the broader role of animal behaviour and landscape utilisation on the transmission dynamics of Hendra virus.

    Full text: The existence of the earth around us is a result of heat and pressure combined to form the very crust we stand on. With such a good model, scientists working throughout the nuclear fuel cycle have used these principles to optimise each particular step. From the fabrication of fuel rods and running of reactors to the final storage of the waste generated; heat and pressure have proved to be vital resources. At ANSTO the concepts of using heat and pressure to consolidate the waste produced for the nuclear fuel cycle have been extensively investigated. Working with collaborators, it has been demonstrated that the intermediate to high level waste can be incorporated into a ceramic or glass-ceramic matrix and immobilised therein, using heat and pressure via the means of a Hot Isostatic Press. This paper touches on how following the simple principles of heat and pressure utilised in the operation of this planet every day, the nuclear fuel cycle can be most efficient. The main focus has been the utilisation of Hot Isostatic Pressing for the production of various durable wasteforms at ANSTO for both Australian and international wastes

    2008-01-01

    The utilisation of renewable energy sources, and wind energy in particular, can be described in Greece as a story of high expectations, intense initial entrepreneurial interest, delays in the start-up phase of projects and, some times, disappointments during the implementation procedure. Still, the current situation gives reasons for some optimism. This paper provides a review of the present technological background in wind generators, as found in the Greek market, as well as a detailed analysis of the legislative framework. Moreover, it aims to analyse the development of the process of granting investment and production permissions and their implementation since 1999. Thus, it is possible to identify the main reasons for the problems that occurred since the liberalisation of the electricity market and to account for the interest in wind energy. Finally, comments and proposals are formulated concerning the hidden barriers, the pertinent problems and the promising perspectives of the use of wind energy in Greece. (author)

  15. Hospital Resource Utilisation by Patients with Community-Acquired Pneumonia

    LENUS (Irish Health Repository)

    2017-09-01

    Little data is available on the resource utilisation of patients admitted with Community-Acquired Pneumonia (CAP) in Ireland. A retrospective review of 50 randomly-selected patients admitted to Beaumont Hospital with CAP was undertaken. The mean length of stay of patients with CAP was 12 days (+\\/- 16 days). All patients were emergency admissions, all had a chest x-ray, a C-reactive protein blood test, and occupied a public bed at some point during admission. Common antimicrobial therapies were intravenous (IV) amoxicillin\\/clavulanic acid and oral clarithromycin; 60% received physiotherapy. The estimated mean cost of CAP per patient was €14,802.17. Costs arising from admission to hospital with CAP are substantial, but efforts can be undertaken to ensure that resources are used efficiently to improve patient care such as discharge planning and fewer in-hospital ward transfers

  16. Current and potential utilisation of biomass energy in Fiji

    Prasad, S.

    1990-01-01

    Energy from biomass accounts for an average of 43% of the primary energy used in developing countries, with some countries totally dependent on biomass for all their energy needs. The most common use for biomass for energy is the provision of heat for cooking and heating; other uses include steam and electricity generation and crop and food drying. Fiji, a developing country, uses energy from wood and coconut wastes for cooking and copra drying. Bagasse from sugar mills is used to generate process steam as well as some 15 MW of electricity, for mill consumption and for sale to the national grid. Other, relatively small scale uses for biomass include the generation of steam and electricity for industry. This paper attempts to quantify the amount of biomass, in its various forms, available in Fiji and assesses the current potential utilisation of biomass for energy in Fiji. (author)

    A cross sectional cluster survey was done in all health wards of Lebowa in May 1992. The study was based on a recall of antenatal, intrapartum and postnatal experience during the last pregnancy of 2940 mothers. Only mothers who delivered within 12 months before the date of interview were included. Antenatal coverage was high at 93.5%, the proportion of health facility deliveries was 74.6% while 26.3% of all births occurred at home. Inaccessibility of maternity services, lack of money, negative staff attitudes and lack of privacy were the common reasons given for preference of home delivery. Mothers who delivered at home were more likely to be of higher parity and unbooked than their counterparts who delivered in a health facility. Postnatal coverage was 50.7% with a 25.4% rate of utilisation of a method of childspacing. The proportion of births attended to by trained personnel needs to be increased.

    The need to remove the bulk of ash contained in flue gas from coal-fired power plants coupled with increasingly strict environmental regulations in the USA result in increased generation of solid materials referred to as coal utilisation by-products, or CUBs. More than 40% of CUBs were sold or reused in the USA in 2004 compared to less than 25% in 1996. A goal of 50% utilization has been established for 2010. The American Coal Ash Association (ACCA) together with the US Department of Energy's Power Plant Improvement Initiative (PPPI) and Clean Coal Power Initiative (CCPI) sponsor a number of projects that promote CUB utilization. Several are mentioned in this report. Report sections are: Executive summary; Introduction; Where do CUBs come from?; Market analysis; DOE-sponsored CUB demonstrations; Examples of best-practice utilization of CUB materials; Factors limiting the use of CUBs; and Conclusions. 14 refs., 1 fig., 5 tabs., 14 photos.

    PURPOSE: Montelukast is a leukotriene receptor antagonist used in asthma and rhinitis treatment. Despite being marketed nearly two decades ago, little is known about its utilisation pattern. METHODS: Using the Danish National Prescription Registry, we identified subjects filling a montelukast...... montelukast initiators, 60% filled at least one prescription of short-acting beta-2-agonists (SABA) up to a year prior to montelukast initiation, and 49% filled a prescription of inhaled corticosteroids (ICS). Only 0.8% (n = 1148) of all individuals initiated montelukast without a redeemed prescription...... of short- or long-term inhalation therapy, systemic antihistamines, or nasal topical anti-allergic treatment. CONCLUSIONS: The usage of montelukast has increased over threefold since its market entry in 1998, mainly driven by an increased number of prevalent users.

    In view of recent events and the resulting emotional and political decisions, the issue of sewage sludge treatment and disposal in Germany. must be seen in a new light. First, a new concept for sewage sludge management must be developed as recent legislation interferes with the 'classic' strategy of utilisation in agriculture, dumping and combustion. Scientists and sewage plant owners must find new ways to implement the specifications of the Act on Recycling and Waste Management. This ATV-DVWK training course discusses subjects that may be helpful on the new path. Starting from current legislation, problems, decision criteria and cost of sewage sludge treatment are gone into. Dimensioning fundamentals for sewage treatment plants re presented, and new and established treatment methods, operational problems and pollution problems are discussed. Further subjects are recycling of useful materials from sewage sludge, co-treatment of organic materials in fermenters, and disposal concepts for small and medium-sized communities. (orig.)

    Over the past 20 years, Participatory Forest Management (PFM) has become a dominant forest management strategy in Tanzania, covering more than 4.1 million hectares. Sustainable forest use and supply of wood products to local people are major aims of PFM. This paper assesses the sustainability...... of forest utilisation under PFM, using estimates of forest condition and extraction rates based on forest inventories and 480 household surveys from 12 forests; seven under Community Based Forest Management (CBFM), three under Joint Forest Management (JFM) and two under government management (non......-PFM). Extraction of products is intense in forests close to Dar es Salaam, regardless of management regime. Further from Dar es Salaam, harvesting levels in forests under PFM are, with one prominent exception, broadly sustainable. Using GIS data from 116 wards, it is shown that half of the PFM forests in Tanzania...

  2. Ethanol production by recombinant and natural xylose-utilising yeasts

    2000-07-01

    The xylose-fermenting capacity of recombinant Saccharomyces cerevisiae carrying XYL1 and XYL2 from Pichia stipitis, which encode xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, is poor due to high xylitol formation. Whereas, P. stipitis exhibits high ethanol yield on xylose, the tolerance towards inhibitors in the lignocellulosic hydrolysate is low. A recombinant strain possessing the advantageous characteristics of both S. cerevisiae and P. stipitis would constitute a biocatalyst capable of efficient ethanol production from lignocellulosic hydrolysate. In the work presented in this thesis, factors influencing xylose fermentation in recombinant S. cerevisiae and in the natural xylose-fermenting yeast P. stipitis have been identified and investigated. Anaerobic xylulose fermentation was compared in strains of Zygosaccharomyces and S. cerevisiae, mutants and wild-type strains to identify host strain background and genetic modifications beneficial for xylose fermentation. The greatest positive effect was found for over-expression of the gene XKS1 for the pentose phosphate pathway (PPP) enzyme xylulokinase (XK), which increased the ethanol yield by almost 85%. The Zygosaccharomyces strains tested formed large amounts of polyols, making them unsuitable as host strains. The XR/XDH/XK ratio was found to determine whether carbon accumulated in a xylitol pool or was further utilised for ethanol production in recombinant xylose-utilising S. cerevisiae. Simulations, based on a kinetic model, and anaerobic xylose cultivation experiments implied that a 1:{>=}10:{>=}4 relation was optimal in minimising xylitol formation. Ethanol formation increased with decreasing XR/XDH ratio, whereas xylitol formation decreased and XK overexpression was necessary for adequate ethanol formation. Based on the knowledge of optimal enzyme ratios, a stable, xylose-utilising strain, S. cerevisiae TMB 3001, was constructed by chromosomal integration of the XYL1 and XYL2 genes

    Over 1 year, private swimming pools in Australia will typically consume 1680 GWh of electricity, producing 2130 kt of CO{sub 2}. Redesigning a pool's filtration system and using it more efficiently can reduce the energy use, and hence the CO{sub 2} production, by a significant amount. This paper describes experimental measurements carried out on a new design of pool pump system. Initial experiments using a variable frequency drive (VFD) with a standard, single phase pump/motor system have achieved energy savings of 40%. Utilising a VFD and a three phase pump/motor energy savings of 61% have been achieved, without degrading the system performance. (author)

    2008-06-01

    Numerous studies have stated that humans need to utilise full sun radiation, at certain times of the day, to assist the body in synthesising the required levels of vitamin D3. The time needed to be spent in the full sun depends on a number of factors, for example, age, skin type, latitude, solar zenith angle. Current Australian guidelines suggest exposure to approximately 1/6 to 1/3 of a minimum erythemal dose (MED), depending on age, would be appropriate to provide adequate vitamin D3 levels. The aim of the study was to determine the exposure times to diffuse solar UV to receive exposures of 1/6 and 1/3 MED for a changing solar zenith angle in order to assess the possible role that diffuse UV (scattered radiation) may play in vitamin D3 effective UV exposures (UVD3). Diffuse and global erythemal UV measurements were conducted at five minute intervals over a twelve month period for a solar zenith angle range of 4° to 80° at a latitude of 27.6° S. For a diffuse UV exposure of 1/3 MED, solar zenith angles smaller than approximately 50° can be utilised for exposure times of less than 10 min. Spectral measurements showed that, for a solar zenith angle of 40°, the UVA (315-400 nm) in the diffuse component of the solar UV is reduced by approximately 62% compared to the UVA in the global UV, whereas UVD3 wavelengths are only reduced by approximately 43%. At certain latitudes, diffuse UV under shade may play an important role in providing the human body with adequate levels of UVD3 (290-315 nm) radiation without experiencing the high levels of UVA observed in full sun.

    The study aimed to (1) determine the trends in the utilisation of metformin in Australia, (2) determine the appropriateness of metformin dosing in an Australian teaching hospital and (3) gather the opinions of prescribers on the relationship between metformin dose and renal function. National prescription data between 1990 and 2012 were accessed. A retrospective audit (2008-2012) of metformin doses and patient renal function (20 % random sample of all in-patients prescribed metformin) was conducted at St Vincent's Hospital (SVH), Sydney. Prescribers of metformin were interviewed (semi-structured; consultants at SVH) or surveyed (Australian endocrinologists) to gather their understanding of metformin dosing in relation to renal function. Metformin utilisation increased fivefold nationally between 1995 and 2012. Metformin tended to be under-dosed in SVH patients with normal renal function (83.5 %) and over-dosed in patients with impaired renal function (estimated glomerular filtration rate (eGFR) metformin doses needed to be reduced in renal impairment. Most endocrinologists (61 %) were comfortable prescribing metformin down to eGFRs around 30 mL/min. The use of metformin increased greatly over the period of the study. Metformin is prescribed frequently for patients with eGFR values below the minimal level approved in the product label (60 mL/min). While prescribers expressed their understanding of the need to reduce metformin doses in patients with renal impairment, we found that metformin doses were higher than appropriate in patients with impaired renal function. Metformin may be used safely when renal function is poor provided dosage is appropriately reduced.

    Full Text Available Depuis longtemps, la Commission, le Parlement et le Conseil encouragent le développement des sources d’énergie renouvelables, et plus particulièrement des biocarburants. Cela s’est traduit, entre autres, par la publication en novembre 2000 d’un livre vert intitulé « Vers une stratégie européenne de sécurité d’approvisionnement énergétique », qui fixe comme objectif, d’ici 2020, le remplacement de 20% des carburants classiques par des carburants de substitution pour le transport routier. Plus récemment, en juin 2001, au sommet de Göteborg, a été souligné le rôle important des biocarburants dans la lutte contre le changement climatique et le développement des énergies propres. Ces encouragements restaient au niveau de la déclaration d’intention faute de moyens administratifs et fiscaux pour bâtir une véritable stratégie. Depuis le 7 novembre 2001, les choses semblent évoluer : en effet, à cette date, le collège des Commissaires a adopté une communication sur les carburants de substitution pour les transports routiers et une série de mesures visant à promouvoir l’utilisation des biocarburants. De plus - et c’est ce qui est fondamental - cette communication était assortie de deux propositions de directives, l’une visant à promouvoir l’utilisation des biocarburants dans les transports, l’autre concernant la possibilité d’appliquer un taux d’accises réduit sur certaines huiles minérales qui contiennent des biocarburants et sur les biocarburants.

  8. Relationship between the utilisation profile of individual joints and their susceptibility to primary osteoarthritis

    Alexander, C.J.

    1989-01-01

    Two subjects were studied for 1 to 3 weeks during the course of their normal domestic activities. Utilisation profiles were derived for ten joints, using a systematic time-series sampling technique adapted from behavioural biology. At each joint the proportion of the available range utilised was noted. The results were compared with the known regional prevalence of primary osteoarthritis. There was a correlation between the degree to which a joint was incompletely utilised, and its susceptibility to osteoarthritis. The hypothesis is advanced that primary osteoarthritis may be due to incomplete joint utilisation. (orig.)

    CO 2 utilisation technologies—also called carbon dioxide utilisation (CDU) and carbon capture and utilisation (CCU)—convert CO 2 via physical, chemical, or biological processes into carbon-based products. CO 2 utilisation technologies are viewed as a means of helping to address climate change and broadening the raw material base for commodities that can be sold to generate economic revenue. However, while technical research and development into the feasibility of CO 2 utilisation options are accelerating rapidly; at present, there has been limited research into the social acceptance of the technology and CO 2 -derived products. This review article outlines and explores three key dimensions of social acceptance (i.e., socio-political, market, and community acceptance) pertaining to innovation within CO 2 utilisation. The article highlights the importance of considering issues of social acceptance as an aspect of the research, development, demonstration, and deployment process for CO 2 utilisation and explores how key stakeholders operating on each dimension might affect the innovation pathways, investment, and siting decisions relating to CO 2 utilisation facilities and CO 2 -derived products. Beyond providing a state-of-the-art review of current research into the social acceptance of CO 2 utilisation, this article also outlines an agenda for future research in the field.

    CO{sub 2} utilisation technologies—also called carbon dioxide utilisation (CDU) and carbon capture and utilisation (CCU)—convert CO{sub 2}via physical, chemical, or biological processes into carbon-based products. CO{sub 2} utilisation technologies are viewed as a means of helping to address climate change and broadening the raw material base for commodities that can be sold to generate economic revenue. However, while technical research and development into the feasibility of CO{sub 2} utilisation options are accelerating rapidly; at present, there has been limited research into the social acceptance of the technology and CO{sub 2}-derived products. This review article outlines and explores three key dimensions of social acceptance (i.e., socio-political, market, and community acceptance) pertaining to innovation within CO{sub 2} utilisation. The article highlights the importance of considering issues of social acceptance as an aspect of the research, development, demonstration, and deployment process for CO{sub 2} utilisation and explores how key stakeholders operating on each dimension might affect the innovation pathways, investment, and siting decisions relating to CO{sub 2} utilisation facilities and CO{sub 2}-derived products. Beyond providing a state-of-the-art review of current research into the social acceptance of CO{sub 2} utilisation, this article also outlines an agenda for future research in the field.

    The objectives of this study were to investigate to what extent biofuels can be said to be climate neutral. An assessment of greenhouse gas emissions from the production and utilisation chains of a number of solid biofuels were made based on data available in the literature. The data has been used for making radiative forcing calculations. The study also includes a comparison between imported and domestic solid biofuels. We conclude that none of the investigated biofuel chains are 'climate neutral', since all of them result in net emissions of greenhouse gases. However, all of the chains result in lower emissions than corresponding emissions from the use of fossil fuels. The emission estimates for the fuel chains varies depending on fuels and on how system boundaries have been set in the different studies. The following factors can contribute significantly to the total emissions of greenhouse gases of the production and utilisation chain of a biofuel: impact of production system on soil carbon storage, land use methods (especially use of drained peatlands), the use of fertilisers (both direct and indirect), combustion technology, refining of the fuel (i.e. pelletisation) and storage (especially of comminuted fuels). Other sources that also contribute to the emissions during a production and utilisation chain are; harvesting machines, transportation and waste handling. The climate impacts of the greenhouse gas emissions from one of the biofuels, i.e. forest residues, were compared to the impacts of fossil fuels by the concept of radiative forcing. In the radiative forcing calculations the CO 2 emissions from combustion of biofuels and the CO 2 emissions that would have occurred if the residues had been left in the forest to decompose were included, and their different dynamics taken into consideration. The decomposition results in CO 2 emissions during a long time period and in an amount equalling those that are emitted during combustion. Only a minor part is due to

    Full Text Available Les armes cybernétiques sont à présent une extension du pouvoir de l’Etat. Dans l’espoir de gagner un avantage stratégique, un certain nombre de pays, dont les Etats-Unis, la Russie et la Chine sont en train de développer des cyber-capacités offensives afin de perturber les institutions politiques, économiques, et sociales de nations concurrentes. Ces activités ont conduit à une course aux armes cybernétiques qui se développe de manière incontrôlable. L’imminence de cette menace globale incite la communauté internationale à la pro-activité. L’objectif de cet article est de proposer une convention internationale afin de mettre un terme au développement, à la prolifération, et à l’utilisation d’armes cybernétiques avant qu’elles ne causent un Armageddon électronique. Nous commencerons d’abord par l’examen de trois efforts successifs de contrôle des armements, puis en utiliserons les leçons retenues pour rédiger une convention pouvant servir de point de départ à des négociations multilatérales.

  13. Possibilities for the efficient utilisation of spent geothermal waters.

    2014-10-01

    Waters located at greater depths usually exhibit high mineral content, which necessitates the use of closed systems, i.e. re-injecting them into the formation after recovering the heat. This significantly reduces investment efficiency owing to the need to drill absorption wells and to perform anti-corrosion and anti-clogging procedures. In this paper, possibilities for the efficient utilisation of cooled geothermal waters are considered, particularly with respect to open or mixed geothermal water installations. Where cooled water desalination technologies are used, this allows the water to be demineralised and used to meet local needs (as drinking water and for leisure purposes). The retentate left as a by-product of the process contains valuable ingredients that can be used for balneological and/or leisure purposes. Thus, the technology for desalinating spent geothermal waters with high mineral content allows improved water management on a local scale and makes it possible to minimise the environmental threat resulting from the need to dump these waters into waterways or surface water bodies and/or inject them into the formation. The paper is concerned with Polish geothermal system and provides information about the parameters of Polish geothermal waters.

  14. Wastewaters from the bioconversion of biomass. Utilisation and treatment

    Developed technology for the bioconversion of biomass into energy forms falls into two categories: biogasification and bioliquefaction. Biogasification is the anaerobic fermentation of organic matter by a mixed culture of organisms to produce a gaseous mixture of methane and carbon dioxide. Bioliquefaction is the use of a pure culture of organisms (mainly yeasts) to anaerobically ferment sugars into a range of liquid products with acetone, butanol, and ethanol being the most commonly produced. Biological processes have the advantage of occurring at ambient, or relatively low (35-60[sup o]C) temperature, at atmospheric pressure, in dilute substrate, in an aqueous environment. Conversion of raw material to gas or liquid fuel is generally incomplete, leaving the non-convertible residues (organic or inorganic) in solution. Hence, biological processes potentially generate large volumes of wastewater containing significant levels of pollutants. This review briefly describes the two bioconversion process routes and then considers each process separately in relation to the characteristics, utilisation and treatment of the specific wastewaters produced by the process.

    Full Text Available Dust generated at an electric arc furnace during steel production industry is still not a solved problem. Electric arc furnace dust (EAF is a hazardous solid waste. Sintering of well-prepared briquetted mixtures in a shaft furnace is one of possible methods of EAFD utilisation. Simultaneously some metal oxides from exhaust gases can be separated. In this way, various metals are obtained, particularly zinc is recovered. As a result, zinc-free briquettes are received with high iron content which can be used in the steelmaking process. The purpose of the research was selecting the appropriate chemical composition of briquettes of the required strength and coke content necessary for the reduction of zinc oxide in a shaft furnace. Based on the results of the research the composition of the briquettes was selected. The best binder hydrated lime and sugar molasses and the range of proper moisture of mixture to receive briquettes of high mechanical strength were also chosen and tested. Additionally, in order to determine the thermal stability for the selected mixtures for briquetting thermal analysis was performed. A technological line of briquetting was developed to apply in a steelworks.

    Statutory agents have stipulated that research activity is a fundamental component of the healthcare professional's activity. Whilst the College of Radiographers have emphasised the importance of imaging personnel embracing this research ethos, there is little available data on the level of research activity within sonographic practice or on the factors that influence a sonographer's involvement in research activities. This work attempts to address these deficiencies. A questionnaire was sent to 300 UK-based sonographers of whom 218 responded (72%). The questionnaire was specifically designed to establish the level of involvement in research, the utilisation of research findings, attitudes towards research and perceived barriers to active research involvement. Responses were analysed investigating any correlations with the population demographics. The data collected showed the majority of sonographers (89%) were enthusiastic about research but with only 33% and 60% currently or previously performing research, respectively, and 73% using research findings to modify their clinical practice. Certain barriers to an active research involvement were shown, with 63%, 55% and 40% citing lack of time, education and collegial support, respectively. A range of statistical findings were linked to particular sonographer groups. The importance of good organisational structures and effective support from fellow health professionals was highlighted. The results confirm sonographers' appreciation of the benefits of research and it is suggested that if this enthusiasm is translated into effective research strategies, research output from ultrasound and other clinical departments should be enhanced.

    The project aims at developing new distributed biorefineries and comprehensive concepts based on slow pyrolysis for SMEs. The research carried out in the project 'Hidaspyro' will be continued in the new project. The goal is an optimised slow pyrolysis process for new applications of the products. The objective is to determine the effects of biochar and distillates on growth of plants, soil improvement, carbon sequestration and emissions of cultivation, to define the quality criteria of biochar, to determine the potential of distillates in odour prevention and to assess the environmental impacts of the products. Optimal process parameters to produce distillates and biochar of high quality will be determined by well-controlled laboratory-scale slow pyrolysis testing facility to be constructed. The main feedstock material will be birchwood, but comparisons with other biomass feedstocks will also be carried out. The efficacy tests will show the effect of biochars and distillates on growth of plants, use of water and nutrients, and biological activity of soil. Demonstrations of soil improvement and odour prevention will be done in co-operation with the partner enterprises. The environmental effects of different biochars will be compared by following the changes in the activity of microbes and the composition of nematode community. The amount and quality of distillate and biochar safe to the environment will be defined. All the results will be utilised in the techno-economic assessment of different concepts. (orig.)

    2018-02-01

    Full Text Available Proline is the predominant amino acid in grape juice, but it is poorly assimilated by wine yeast under the anaerobic conditions typical of most fermentations. Exploiting the abundance of this naturally occurring nitrogen source to overcome the need for nitrogen supplementation and/or the risk of stuck or sluggish fermentations would be most beneficial. This study describes the isolation and evaluation of a novel wine yeast isolate, Q7, obtained through ethyl methanesulfonate (EMS mutagenesis. The utilisation of proline by the EMS isolate was markedly higher than by the QA23 wild type strain, with approximately 700 and 300 mg/L more consumed under aerobic and self-anaerobic fermentation conditions, respectively, in the presence of preferred nitrogen sources. Higher intracellular proline contents in the wild type strain implied a lesser rate of proline catabolism or incorporation by this strain, but with higher cell viability after freezing treatment. The expression of key genes (PUT1, PUT2, PUT3, PUT4, GAP1 and URE2 involved in proline degradation, transport and repression were compared between the parent strain and the isolate, revealing key differences. The application of these strains for efficient conduct for nitrogen-limited fermentations is a possibility.

    Full Text Available The study investigated how Catholic-sponsored community colleges in Nairobi utilise the existing physical facilities and teaching and learning resources for effective implementation of Artisan and Craft curricula. The study adopted a mixed methods research design. Proportional stratified random sampling was used to sample 172 students and 18 teachers while four directors of community colleges were purposively selected. Questionnaires were administered to students and teachers, while directors were interviewed. Teaching and learning resources, such as workshops, equipment, lecture rooms, laboratories, raw materials for practical training and reference books, were found to be adequate, although underutilised. However, sports grounds, libraries and course texts were inadequate. Resource inadequacies were often mitigated by signing equipment co-sharing agreements with peer institutions and local firms. Teachers rated highly the influence of physical facilities on curriculum implementation. Both students and teachers rated highly the influence of teaching and learning resources on curriculum implementation. The study concludes that, while some physical facilities and teaching and learning resources are adequate, their underutilisation and the inadequacy of other core facilities and resources, such as libraries and course textbooks, hinder effective teaching and learning in these community colleges.

    New technologies are assuming a relevant importance in the Space business domain also in the Assembly Integration and Test (AIT) activities allowing process optimization and capability that were unthinkable only few years ago. This paper has the aim to describe Alenia Spazio (ALS) gained experience on the remote interaction techniques as a results of collaborations established both on European Communities (EC) initiatives, with Alenia Aeronautica (ALA) and Politecnico of Torino (POLITO). The H/W and S/W components performances increase and costs reduction due to the home computing massive utilization (especially demanded by the games business) together with the network technology possibility (offered by the web as well as the hi-speed links and the wireless communications) allow today to re-think the traditional AIT process activities in the light of the multimedia data exchange: graphical, voice video and by sure more in the future. Aerospace business confirm its innovation vocation which in the year '80 represents the cradle of the CAD systems and today is oriented to the 3D data visualization/ interaction technologies and remote visualisation/ interaction in collaborative way on a much more user friendly bases (i.e. not for specialists). Fig. 1 collects AIT extended scenario studied and adopted by ALS in these years. ALS experimented two possibilities of remote visualization/interaction: Portable [e.g. Fig.2 Personal Digital Assistant (PDA), Wearable] and walls (e.g.VR-Lab) screens as both 2D/3D visualisation and interaction devices which could support many types of traditional (mainly based on EGSE and PDM/CAD utilisation/reports) company internal AIT applications: 1. design review support 2. facility management 3. storage management 4. personnel training 5. integration sequences definition 6. assembly and test operations follow up 7. documentation review and external access to AIT activities for remote operations (e.g. tele-testing) EGSE Portable Clean room

  1. Utilisation of prompt fission neutron technology in Greenfields uranium exploration

    Mutz, P.R.

    2007-01-01

    Conventionally, gamma detection technology has been used in uranium exploration programs for the initial detection of uranium as well as for a determination of uranium concentration. Geophysical logging companies use wireline gamma probes to measure uranium within boreholes, and field technicians utilise hand held gamma meters to detect uranium in rock samples, drill cuttings and cores. Borehole geophysical logging equipment typically records the uranium concentration as %eU 3 O8, where e represents an equivalent determination of uranium concentration as opposed to a laboratory assay. This method of uranium determination is an indirect method, as it measures gamma radiation from uranium-238 (U-238) isotope decay chain progeny; principally the bismuth-214 (Bi-214) isotope. Consequently, the uranium determination can be inaccurate due to natural disequilibrium between the U-238 parent and the decay chain progeny. This is especially true in sedimentary hosted uranium deposits, where the uranium and daughter progeny may have been geochemically separated. The gamma detection method for uranium can also be rendered inaccurate by detecting the gamma signature from potassium in clays as well as from thorium; both of which can provide a false (enhanced) eU 3 O8 determination. Prompt Fission Neutron (PFN) technology is a geophysical wireline logging technology used in the same manner as conventional gamma logging. The difference is that PFN provides a direct determination of uranium within a borehole, irrespective of natural disequilibrium or the presence of other radioactive elements. This paper provides a brief description of natural uranium and radioactivity as a basis for explaining the conventional use of gamma radiation detectors for the detection and determination of uranium concentration in exploration boreholes, including the potential pitfalls of this technology. A detailed description of prompt fission neutron technology is also presented, along with a discussion

  2. Structural insight into the Clostridium difficile ethanolamine utilisation microcompartment.

    Directory of Open Access Journals (Sweden)

    Alison C Pitts

    Full Text Available Bacterial microcompartments form a protective proteinaceous barrier around metabolic enzymes that process unstable or toxic chemical intermediates. The genome of the virulent, multidrug-resistant Clostridium difficile 630 strain contains an operon, eut, encoding a bacterial microcompartment with genes for the breakdown of ethanolamine and its utilisation as a source of reduced nitrogen and carbon. The C. difficile eut operon displays regulatory genetic elements and protein encoding regions in common with homologous loci found in the genomes of other bacteria, including the enteric pathogens Salmonella enterica and Enterococcus faecalis. The crystal structures of two microcompartment shell proteins, CD1908 and CD1918, and an uncharacterised protein with potential enzymatic activity, CD1925, were determined by X-ray crystallography. CD1908 and CD1918 display the same protein fold, though the order of secondary structure elements is permuted in CD1908 and this protein displays an N-terminal β-strand extension. These proteins form hexamers with molecules related by crystallographic and non-crystallographic symmetry. The structure of CD1925 has a cupin β-barrel fold and a putative active site that is distinct from the metal-ion dependent catalytic cupins. Thin-section transmission electron microscopy of Escherichia coli over-expressing eut proteins indicates that CD1918 is capable of self-association into arrays, suggesting an organisational role for CD1918 in the formation of this microcompartment. The work presented provides the basis for further study of the architecture and function of the C. difficile eut microcompartment, its role in metabolism and the wider consequences of intestinal colonisation and virulence in this pathogen.

    The phosphatidylinositol-3-kinase (PI3K-PKB), mitogen activated protein kinase (MEK-ERK) and the mammalian target of rapamycin (mTOR- p70S6K), are thought to regulate many aspects of tumour cell proliferation and survival. We have examined the utilisation of these three signalling pathways in a number of cell lines derived from patients with metastatic malignant melanoma of known PIK3CA, PTEN, NRAS and BRAF mutational status. Western blotting was used to compare the phosphorylation status of components of the PI3K-PKB, MEK-ERK and mTOR-p70S6K signalling pathways, as indices of pathway utilisation. Normal melanocytes could not be distinguished from melanoma cells on the basis of pathway utilisation when grown in the presence of serum, but could be distinguished upon serum starvation, where signalling protein phosphorylation was generally abrogated. Surprisingly, the differential utilisation of individual pathways was not consistently associated with the presence of an oncogenic or tumour suppressor mutation of genes in these pathways. Utilisation of the PI3K-PKB, MEK-ERK and mTOR-p70S6K signalling pathways in melanoma, as determined by phosphorylation of signalling components, varies widely across a series of cell lines, and does not directly reflect mutation of genes coding these components. The main difference between cultured normal melanocytes and melanoma cells is not the pathway utilisation itself, but rather in the serum dependence of pathway utilisation

    While living overseas in another culture, retirees need to adapt to a new environment but often this causes difficulties, particularly among those elderly who require healthcare services. This study examines factors affecting healthcare service utilisation among Japanese retirees in Malaysia. We conducted 6 focus group discussions with Japanese retirees and interviewed 8 relevant medical services providers in-depth. Guided by the Andersen Healthcare Utilisation Model, we managed and analysed the data, using QSR NVivo 10 software and the directed content analysis method. We interviewed participants at Japan Clubs and their offices. 30 Japanese retirees who live in Kuala Lumpur and Ipoh, and 8 medical services providers. We identified health beliefs, medical symptoms and health insurance as the 3 most important themes, respectively, representing the 3 dimensions within the Andersen Healthcare Utilisation Model. Additionally, language barriers, voluntary health repatriation to Japan and psychological support were unique themes that influence healthcare service utilisation among Japanese retirees. The healthcare service utilisation among Japanese retirees in Malaysia could be partially explained by the Andersen Healthcare Utilisation Model, together with some factors that were unique findings to this study. Healthcare service utilisation among Japanese retirees in Malaysia could be improved by alleviating negative health beliefs through awareness programmes for Japanese retirees about the healthcare systems and cultural aspects of medical care in Malaysia.

    Full Text Available Access to quality healthcare still remains a major challenge in the efforts at reversing maternal morbidity and mortality. Despite the availability of established maternal health interventions, the health of the expectant mother and the unborn child remains poor due to low utilisation of interventions. The study examined the socioeconomic determinants of antenatal care utilisation in peri-urban Ghana using pregnant women who are in their third trimester. Two-stage sampling technique was used to sample 200 pregnant women who were in their third trimester from the District Health Information Management System software. Well-structured questionnaire was the instrument used to collect data from respondents. Descriptive statistics and inferential statistics including binary logit regression model were used to analyse the data with the help of SPSS and STATA software. The results showed varying utilisation levels of ANC. From the regression result, age, household size, and occupational status were identified as the important socioeconomic determinants of antenatal care utilisation among the respondents. The important system factors which influence antenatal care utilisation by the respondents are distance to ANC, quality of service, and service satisfaction. The study concludes that socioeconomic and health system factors are important determinants of antenatal care utilisation. Stepping up of interventions aimed at improving the socioeconomic status and addressing health system and proximity challenges could be helpful in improving antenatal care utilisation by pregnant women in Ghana.

    We sought to benchmark the utilisation of echocardiography in the outpatient evaluation of heart murmurs by evaluating two large paediatric cardiology centres. Although criteria exist for appropriate use of echocardiography, there are no benchmarking data demonstrating its utilisation. We performed a retrospective cohort study of outpatients aged between 0 and 18 years at the Sibley Heart Center Cardiology and the Children's Hospital of Philadelphia Division of Cardiology, given a sole diagnosis of "innocent murmur" from 1 July, 2007 to 31 October, 2010. Using internal claims data, we compared the utilisation of echocardiography according to centre, patient age, and physician years of service. Of 23,114 eligible patients (Sibley Heart Center Cardiology: 12,815, Children's Hospital of Philadelphia Division of Cardiology: 10,299), 43.1% (Sibley Heart Center Cardiology: 45.2%, Children's Hospital of Philadelphia Division of Cardiology: 40.4%; p1-5 years had the lowest utilisation (32.7%). In two large paediatric cardiology practices, the overall utilisation of echocardiography by physicians with a sole diagnosis of innocent murmur was similar. There was significant and similar variability in utilisation by provider at both centres. Although these data serve as initial benchmarking, the variability in utilisation highlights the importance of appropriate use criteria.

    Strong wind, high rainfall, the spread of diseases during rainy season and pests problems in open field agriculture have led to the current trend in growing vegetables under protected environment. The occurrence of soil borne disease, and limited suitable land for agriculture are some of the reasons to look for alternative media such as coconut coir dust. The basic properties of coconut coir dust as a soil less growing medium and the utilisation of nitrogen (n) fertiliser for the lowland cauliflower grown in them have not been thoroughly investigated and are therefore not well understood. This study has been conducted by the need to provide a basis for determining optimal levels/ concentration and forms of nitrogen supply, and by the need to minimize environmental consequences of lowland cauliflower production. It focuses on the effects of N supply in terms of different levels of N and ionic N forms in the nutrient solution, on the growth, development and N utilisation of cauliflower grown in coconut coir dust under greenhouse condition in the lowlands. Based on the plant growth parameters studied coconut coir dust was found to be more suitable than oil palm empty fruit bunch as a growing medium. From the growth and development study using coconut coir dust, it can be deduced that the N requirement by the plant is less at later growth stage regardless of low or high level of N in the nutrient solution. However, low level of N of 50 mg l{sup -1} was found to be inadequate for plant growth and curd yield. The N concentration levels of 200 mg l{sup -1} in the nutrient solution optimised both the vegetative and curd production. A somewhat lower level of N (170 mg l{sup -1}) produced curd weight not significantly different from N level of 200 mg l{sup -1}. The plant growth and curd yield was reduced by about 29.0 % at 400 mg N l{sup -1}. The N level of 400 mg l{sup -1} in the nutrient solution may be in excess to that actually required by the plant, resulting in a high

    Water plays a significant role in wetlands. Floodwater utilisation in wetlands brings a wide range of wetland services, from goods production and water regulation to animal protection and aesthetics related to water supply in wetlands. In this study, the floodwater utilisation values of wetland services were estimated within the Momoge wetland and Xianghai wetland in western Jilin province of northeastern China. From 2003 to 2008, the floodwater diverted from the Nenjiang and Tao'er River is 381 million m3, which translates into a monetary value of approximately 1.35 billion RMB in 2008 (RMB: Chinese Currency, RMB 6.80 = US 1), and the ratio of economic value, eco-environmental value, and social value is 1:12:2. Besides the monetary value of the water itself, excessive floodwater utilisation may bring losses to wetlands; the threshold floodwater utilisation volumes in wetlands are discussed. Floodwater utilisation can alleviate water shortages in wetlands, and the evaluation of floodwater utilisation in wetland services in monetary terms is a guide for the effective use of the floodwater resources and for the conservation of wetlands.

    Inequalities in the utilisation of dental services in Brazil are remarkable. The aim of this study was to evaluate the association of contextual and individual factors with the utilisation of dental services by Brazilian adults using the Andersen's behavioural model. Individual-level data from 27,017 adults residents in the State capitals who were interviewed in the 2013 Brazilian National Health Survey were pooled with contextual city-level data. The outcomes were non-utilisation of dental services and last dental visit over 12 months ago. Individual predisposing variables were age, sex, race/skin colour, schooling and social network. Individual enabling variables included income, health insurance and registration in primary health care. Individual need variables were self-perceived dental health and self-reported missing teeth. Multilevel logistic regression models were performed to estimate odds ratio (OR) and 95% confidence intervals (95% CIs) of the association of contextual and individual predisposing, enabling and need-related variables with dental services outcomes. Predisposing (OR = 0.89; 95% CI 0.81-0.97) and enabling (OR = 0.90; 95% CI 0.85-0.96) contextual factors were associated with non-utilisation of dental services. Individual predisposing (sex, race/skin colour, schooling), enabling (income, health insurance) and need (self-perceived oral health, missing teeth) were associated with non-utilisation of dental services and last dental visit over 12 months ago. The latter was also associated with other individual predisposing (age, social network) and need (eating difficulties due to oral problems) characteristics. Individual and contextual determinants influenced dental services utilisation in Brazilian adults. These factors should be on the policy agenda and considered in the organisation of health services aiming to reduce oral health inequalities related to access and utilisation of dental services.

    Full Text Available Abstract Background The aim of this study is to describe the magnitude of educational inequalities in utilisation of general practitioner (GP and specialist services in 9 European countries. In addition to West European countries, we have included 3 Eastern European countries: Hungary, Estonia and Latvia. To cover the gap in knowledge we pay a special attention to the magnitude of inequalities among patients with chronic conditions. Methods Data on the use of GP and specialist services were derived from national health surveys of Belgium, Estonia, France, Germany, Hungary, Ireland, Latvia, the Netherlands and Norway. For each country and education level we calculated the absolute prevalence and relative inequalities in utilisation of GP and specialist services. In order to account for the need for care, the results were adjusted by the measure of self-assessed health. Results People with lower education used GP services equally often in most countries (except Belgium and Germany compared with those with a higher level of education. At the same time people with a higher education used specialist care services significantly more often in all countries, except in the Netherlands. The general pattern of educational inequalities in utilisation of specialist care was similar for both men and women. Inequalities in utilisation of specialist care were equally large in Eastern European and in Western European countries, except for Latvia where the inequalities were somewhat larger. Similarly, large inequalities were found in the utilisation of specialist care among patients with chronic diseases, diabetes, and hypertension. Conclusions We found large inequalities in the utilisation of specialist care. These inequalities were not compensated by utilisation of GP services. Of particular concern is the presence of inequalities among patients with a high need for specialist care, such as those with chronic diseases.

    Biomass feedstock from agriculture can be refined and converted into several different energy carriers and utilised for different energy services, such as production of heat, electricity or transportation fuel. The feedstock may be residues and by-products, such as straw and manure, or energy crops cultivated under different conditions depending on variations in regional and local conditions. Similar variations exist in the regional and local conditions for the refining and utilisation of the bioenergy and its by-products. The overall aim of this report is to analyse and describe the technical and physical conditions of different agriculture-based bioenergy systems using the existing infrastructure and potential new systems expected to be developed in the future. To which extent this technical/physical potential will be utilised in the future depends mainly on economic conditions and financial considerations. These aspects are not included in this study. Furthermore, potential possibilities to utilise existing infrastructure within the forest industry are not included. The report starts with an analysis and description of the energy efficiency of different bioenergy systems, from the production of the biomass to the final use of the refined energy carrier, expressed as the amount of heat, electricity or transportation fuel produced per hectare and year. The possibilities to co-produce different energy carries in bio-refineries are also analysed. The next part of the report includes an analysis of the variation in the regional conditions for the conversion and utilisation of the different energy carriers, based on existing infrastructure, for instance, district heating systems, individual heating systems, combined heat and power production, utilisation of by-products as feed in animal production, utilisation of digestion residues as fertilisers, the supply of forest fuels, etc. The report also includes a discussion of the environmental impact of an increased

    Full Text Available This paper presents the findings of an expert working group of researchers from East Asian countries. The group was tasked with developing a theoretically sound and practically implementable methodology for assessing the sustainability of biomass utilisation in East Asian countries based on the needs and potential of biomass resources in this region. Building on six years of research conducted between 2007 and 2013, the working group formulated a set of main and secondary indicators for biomass utilisation under three pillars of sustainability. For the environmental pillar, the main indicator was life cycle greenhouse gas emissions and secondary indicators were water consumption and soil quality. For the economic pillar, the main indicator was total value added and secondary indicators were net profit, productivity, and net energy balance. For the social pillar, the main indicators were employment generation and access to modern energy, and the secondary indicator was the human development index. The application of the working group methodology and indicators in sustainability assessments of biomass utilisation will enable decision makers in East Asian countries to compare the sustainability of biomass utilisation options and to make decisions on whether or not to launch or sustain biomass utilisation initiatives.

    Little comparative evidence is available on utilisation of cancer medicines in different countries and its determinants. The aim of this study was to develop a statistical model to test the correlation between utilisation and possible determinants in selected European countries. A sample of 31 medicines for cancer treatment that obtained EU-wide marketing authorisation between 2000 and 2012 was selected. Annual data on medicines' utilisation covering the in- and out-patient public sectors were obtained from national authorities between 2008 and 2013. Possible determinants of utilisation were extracted from HTA reports and complemented by contacts with key informants. A longitudinal mixed effect model was fitted to test possible determinants of medicines utilisation in Belgium, Scotland and Sweden. In the all-country model, the number of indications reimbursed positively correlated with increased consumption of medicines [one indication 2.6, 95% CI (1.8-3.6); two indications 2.4, 95% CI (1.4-4.3); three indications 4.9, 95% CI (2.2-10.9); all P marketing authorisation [1.2, 95% CI (1.02-1.4); p marketing authorisation. Prices had a negative effect on consumption in Belgium and Sweden. The positive impact of financial MEAs in Scotland suggests that the latter may remove the regressive effect of list prices on consumption.

    Sludge production will presumably not decrease in future. At present agricultural use of sludge is unstable and landfilling will most probably be restricted in the following years. The objective of this thesis is to gather information on options for sludge treatment and utilisation and to compare these options in order to find the best possible solution for future alternatives of sludge utilisation. Finnish and international literature as well as Finnish and EU legislation have been reviewed. Furthermore the mentoring group of this thesis as well as other experts in Finland have been used as a source of information. Sludge contains not only plant nutrients and organic matter but also varying quantities of a number of more or less hazardous substances. The quality and quantity of sewage sludge are described and possible health and environmental risks caused by sewage sludge are pointed out. The legislation linked to sludge utilisation and its demands are also presented. The sludge processing methods reviewed are: thickening, lime stabilisation, aerobic digestion, anaerobic digestion, composting and mechanical and thermal drying. In addition, the positive and negative sides of the stabilisation processes are looked at in greater detail. Agricultural use, landscaping, forestry, landfill, incineration, sludge derived products and newer processing technologies are reviewed as sludge utilisation options. Their environmental impacts, positive and negative sides and practical feasibility are evaluated. Various treatment utilisation combinations are also compared. Furthermore a rough cost assessment is presented. The optimal utilisation alternative has to be chosen case by case. The best use of plant nutrients and valuable organic matter is obtained in agricultural use or in landscaping. In the present situation it is difficult to enhance the portion of agricultural use, and landscaping is restricted by a low demand on the market. Incineration is an expensive option and can

    Full Text Available Abstract Background To examine the differences in health services utilisation and the associated risk factors between infants from non-English speaking background (NESB and English speaking background (ESB within Australia. Methods We analysed data from a national representative longitudinal study, the Longitudinal Study of Australian Children (LSAC which started in 2004. We used survey logistic regression coupled with survey multiple linear regression to examine the factors associated with health services utilisation. Results Similar health status was observed between the two groups. In comparison to ESB infants, NESB infants were significantly less likely to use the following health services: maternal and child health centres or help lines (odds ratio [OR] 0.56; 95% confidence intervals [CI], 0.40-0.79; maternal and child health nurse visits (OR 0.68; 95% CI, 0.49-0.95; general practitioners (GPs (OR 0.58; 95% CI, 0.40-0.83; and hospital outpatient clinics (OR 0.54; 95% CI, 0.31-0.93. Multivariate analysis results showed that the disparities could not be fully explained by the socioeconomic status and language barriers. The association between English proficiency and the service utilised was absent once the NESB was taken into account. Maternal characteristics, family size and income, private health insurance and region of residence were the key factors associated with health services utilisation. Conclusions NESB infants accessed significantly less of the four most frequently used health services compared with ESB infants. Maternal characteristics and family socioeconomic status were linked to health services utilisation. The gaps in health services utilisation between NESB and ESB infants with regard to the use of maternal and child health centres or phone help, maternal and child health nurse visits, GPs and paediatricians require appropriate policy attentions and interventions.

  5. Adolescents' utilisation of psychiatric care, neighbourhoods and neighbourhood socioeconomic deprivation: a multilevel analysis.

    Anna-Karin Ivert

    Full Text Available Mental health problems among adolescents have become a major public health issue, and it is therefore important to increase knowledge on the contextual determinants of adolescent mental health. One such determinant is the socioeconomic structure of the neighbourhood. The present study has two central objectives, (i to examine if neighbourhood socioeconomic deprivation is associated to individual variations in utilisation of psychiatric care in a Swedish context, and (ii to investigate if neighbourhood boundaries are a valid construct for identifying contexts that influence individual variations in psychiatric care utilization. Data were obtained from the Longitudinal Multilevel Analysis in Scania (LOMAS database. The study population consists of all boys and girls aged 13-18 years (N=18,417, who were living in the city of Malmö, Sweden, in 2005. Multilevel logistic regression analysis was applied to estimate the probability of psychiatric care utilisation. The results from the study indicate that the neighbourhood of residence had little influence on psychiatric care utilisation. Although we initially found a variation between neighbourhoods, this general contextual effect was very small (i.e. 1.6%. The initial conclusive association between the neighbourhood level of disadvantage and psychiatric care utilisation (specific contextual effect disappeared following adjustment for individual and family level variables. Our results suggest the neighbourhoods in Malmö (at least measured in terms of SAMS-areas, do not provide accurate information for discriminating adolescents utilisation of psychiatric care. The SAMS-areas appears to be an inappropriate construct of the social environment that influences adolescent utilisation of psychiatric care. Therefore, public health interventions should be directed to the whole city rather than to specific neighbourhoods. However, since geographical, social or cultural contexts may be important for our

    The paper assesses the energy productivity of the major plantation crops in Malaysia as well as the status of bioenergy utilisation in that country. Of the crops studied and under present local cultivation practices, oil palms and cocoa trees stand out as good trappers of solar energy while paddy plants are the least efficient. Presently, Malaysia consumes roughly 340 million boe of energy per year. Of this amount 14% are contributed by biomass. However of the total amount of biowastes generated in the country roughly 24.5% are already utilised for energy purposes and roughly 75.5% are still unutilised and therefore wasted. (Author)

    The aim of the study was to survey characteristics, utilisation and possible environmental impacts of solid wastes, i.e., in case of biomass, mainly high-temperature filter ash (HTHP) from pressurised fluidised-bed gasification (PFBG). The aim is to utilise solid wastes (slag, filter dust, additives) from biomass gasification instead of dumping. One alternative is recycling to the soil as liming material or fertiliser. It is expected that the ash recycled to forest soils changes the environment less than non-recycled ash. (orig.) 3 refs.

    Proposals have been made for a quantity that can be used to estimate possible detriment from medical radiology better than the ICRP's collective effective dose equivalent. One such approach utilises age and sex dependent 'weighting' factors. The magnitude of the effect obtained by utilising such factors when applied to an actual population has not been previously assessed. When age and sex dependent weighting factors are applied to diagnostic medical radiology for all hospital examinations conducted in the United States in 1980, estimates of detriment are reduced by one-third.

    Soil application of Zn is by far the most common and generally successful method of application to rice. Comparison of the effectiveness of soil applications of Zn necessarily involves simultaneous comparison of different sources. Applying Zn in combination with macronutrient fertilizers is convenient and allows more uniform distribution. Studies have indicated marked differences in Zn availability, uptake and utilisation resulting from the macronutrient fertilizer with which it is applied. This study was undertaken to evaluate the effect of a few sources of Zn on the yield, Zn uptake and utilisation in rice in two major rice grown soil series of Tamil Nadu. (author). 7 refs., 3 tabs

    1995-01-01

    Waste drilling-fluid-utilising microorganisms were isolated from drilling-mud cuttings, soil and creek water from a mangrove swamp oilfield location in the Delta area of Nigeria using waste drilling-fluid as the substrate. Eighteen bacterial isolates obtained were identified as species of Staphylococcus, Acinetobacter, Alcaligenes, Serratia, Clostridium, Enterobacter, Klebsiella, Nocardia, Bacillus, Actinomyces, Micrococcus and Pseudomonas, while the genera of fungi isolated were Penicillium, Cladosporium and Fusarium. Even though drilling-fluid-utilising genera were in higher numbers in the soil than in the two other sources examined, the percentages of the total heterotrophic bacteria that utilised waste drilling-fluid were 6.02 in the drilling-mud cuttings, 0.83 in creek water and 0.42 in soil. The screen tests for biodegradation potential of the bacterial isolates showed that, even though all the isolates were able to degrade and utilise the waste fluid for growth, species of Alcaligenes and Micrococcus were more active degraders of the waste. The significance of the results in environmental management in oil-producing areas of Nigeria is discussed. (Author)

    Permchart, W.; Tanatvanit, S.

    2007-10-01

    This paper summarises the overview of the current situation of alternative energies in Thailand. The utilisation of bio-diesel as an alternative energy in two economic sectors (i.e. transport and industrial sectors), which have the largest energy consumption in the country, is mainly presented because it has seemed to be the most promising project among various energy conservation projects of the Thai government. Actually, there is another bio-fuel project, namely, the ethanol project for blending with gasoline to produce gasohol (E10) used in gasoline engines, which has been developed and already become to an important policy for energy conservation of the country. Due to much more large number of diesel has been utilised, the bio-diesel project has been the first priority one to solve the petroleum crisis problems. However, it is remarked that the utilisation of bio-diesel as an alternative fuel seems to be unsatisfactory because of various reasons. Some issues in terms of both government policies and technical problems have not been clearly addressed. Therefore, this paper not only presents the utilisation of bio-diesel in these two sectors but also discusses the production processes, characterisations and some experimental testing results of bio-diesel.

    Waste drilling-fluid-utilising microorganisms were isolated from drilling-mud cuttings, soil and creek water from a mangrove swamp oilfield location in the Delta area of Nigeria using waste drilling-fluid as the substrate. Eighteen bacterial isolates obtained were identified as species of Staphylococcus, Acinetobacter, Alcaligenes, Serratia, Clostridium, Enterobacter, Klebsiella, Nocardia, Bacillus, Actinomyces, Micrococcus and Pseudomonas, while the genera of fungi isolated were Penicillium, Cladosporium and Fusarium. Even though drilling-fluid-utilising genera were in higher numbers in the soil than in the two other sources examined, the percentages of the total heterotrophic bacteria that utilised waste drilling-fluid were 6.02 in the drilling-mud cuttings, 0.83 in creek water and 0.42 in soil. The screen tests for biodegradation potential of the bacterial isolates showed that, even though all the isolates were able to degrade and utilise the waste fluid for growth, species of Alcaligenes and Micrococcus were more active degraders of the waste. The significance of the results in environmental management in oil-producing areas of Nigeria is discussed. (Author)

  10. The climate impact of energy peat utilisation - comparison and sensitivity analysis of Finnish and Swedish results

    Energy Technology Data Exchange (ETDEWEB)

    Holmgren, Kristina; Kirkinen, Johanna; Savolainen, Ilkka

    2006-06-15

    The climate impact of energy peat utilisation have been studied both in Finland by VTT Technical Research Centre and in Sweden by IVL Swedish Environmental Research Institute Ltd. The main objective of this study is to compare the results of earlier studies by VTT and IVL and to perform a sensitivity analysis of previous and new results. The scientific approach of the two studies is very similar. The climate impact of peat utilisation is considered from a life-cycle point of view by taking into account all phases of the peat utilisation chain. Peat reserves can be both sinks and sources of greenhouse gas emissions as well as there are both uptake and emissions of greenhouse gases during the utilisation chain. The net impact of the utilisation chain is assessed as the climate impact due to the utilisation chain minus the climate impact of non-utilisation chain. The instantaneous radiative forcing and accumulated radiative forcing are used in both studies as the indicator of the climate impact. Radiative forcing is calculated on the basis of the concentration changes due to emissions and uptake of greenhouse gases. The differences in the models for calculating concentrations and radiative forcing are minor. There are some differences in the definitions and boundaries of the considered peat utilisation chains, although the differences in the results due to differences in the chain definitions are small. The main reason for the differences in results between the two studies is differences in emission (and uptake) estimates for the after-treatment phase and the non-utilisation chain. Both Swedish and Finnish studies show that the use of cultivated peatland for energy peat utilisation results in lower climate impact than using coal (within 100 years). Both studies show that the use of pristine mires for peat production will result in larger climate impact than the use of already drained peatlands.

  15. ICT and OTs: a model of information and communication technology acceptance and utilisation by occupational therapists.

    Science.gov (United States)

    Schaper, Louise K; Pervan, Graham P

    2007-06-01

    There is evidence to suggest that health professionals are reluctant to accept and utilise information and communication technologies (ICT) and concern is growing within health informatics research that this is contributing to the lag in adoption and utilisation of ICT across the health sector. Technology acceptance research within the field of information systems has been limited in its application to health and there is a concurrent need to develop and gain empirical support for models of technology acceptance within health and to examine acceptance and utilisation issues amongst health professionals to improve the success of information system implementation in this arena. This paper outlines a project that examines ICT acceptance and utilisation by Australian occupational therapists. It describes the theoretical basis behind the development of a research model and the methodology being employed to empirically validate the model using substantial quantitative, qualitative and longitudinal data. Preliminary results from Phase II of the study are presented. The theoretical significance of this work is that it uses a thoroughly constructed research model, with potentially the largest sample size ever tested, to extend technology acceptance research into the health sector.

    2018-03-23

    Children's exposure to racism via caregiver experience (vicarious racism) is associated with poorer health and development. However, the relationship with child healthcare utilisation is unknown. We aimed to investigate (1) the prevalence of vicarious racism by child ethnicity; (2) the association between caregiver experiences of racism and child healthcare utilisation; and (3) the contribution of caregiver socioeconomic position and psychological distress to this association. Cross-sectional analysis of two instances of the New Zealand Health Survey (2006/2007: n=4535 child-primary caregiver dyads; 2011/2012: n=4420 dyads). Children's unmet need for healthcare, reporting no usual medical centre and caregiver-reported dissatisfaction with their child's medical centre. The prevalence of reporting 'any' experience of racism was higher among caregivers of indigenous Māori and Asian children (30.0% for both groups in 2006/2007) compared with European/Other children (14.4% in 2006/2007). Vicarious racism was independently associated with unmet need for child's healthcare (OR=2.30, 95% CI 1.65 to 3.20) and dissatisfaction with their child's medical centre (OR=2.00, 95% CI 1.26 to 3.16). Importantly, there was a dose-response relationship between the number of reported experiences of racism and child healthcare utilisation (eg, unmet need: 1 report of racism, OR=1.89, 95% CI 1.34 to 2.67; 2+ reports of racism, OR=3.06, 95% CI 1.27 to 7.37). Adjustment for caregiver psychological distress attenuated the association between caregiver experiences of racism and child healthcare utilisation. Vicarious racism is a serious health problem in New Zealand disproportionately affecting Māori and Asian children and significantly impacting children's healthcare utilisation. Tackling racism may be an important means of improving inequities in child healthcare utilisation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  13. Utilising Fine and Coarse Recycled Aggregates from the Gulf Region in Concrete

    Science.gov (United States)

    Jones, M. Rod; Halliday, Judith E.; Csetenyi, Laszlo; Zheng, Li; Strompinis, N.

    This paper explores the feasibility in utilising materials generated from C&DW to produce a `green' concrete. The two materials that are considered here are, (i) up-sizing silt-size material generated from recycled aggregates to produce a synthetic silt-sand and (ii) processed recycled coarse aggregates (RA) sourced from a Gulf Region landfill site. The work has demonstrated that there is potential for utilising silt wastes into foamed concrete, which can then be crushed to a sand-sized material suitable for use in concrete, however the porous nature of the material has highlighted that the water demand of this RA is high. RAs were characterised to BS EN 12620 and found suitable for use in concrete. The effect of RA on concrete properties is minimal when used up to 35% replacement levels, provided that they are pre-soaked.

  14. Sustainability indicator system and policy processes in Malaysia: a framework for utilisation and learning.

    Science.gov (United States)

    Hezri, A A

    2004-12-01

    Formulation of effective sustainability indicators for national assessment demands a comprehensive understanding of the utilisation, diffusion and dissemination of information in policy processes. To illustrate the dynamic of sustainability assessment within the context of policy processes, this paper uses a case study of national sustainability indicators development in Malaysia. Subsequently, this paper ascribes the limited achievement of national sustainability assessment in Malaysia to four types of constraints: meta-policy issues; technical capacities; communication concerns; and the inherent knowledge gaps within the indicator developer community vis-a-vis their theoretical limitations. It is proposed that such constraints will be encountered in many countries. Drawing from the literature on public policy, this paper outlines a framework for investigating indicator behaviour within policy processes based on well-established concepts such as knowledge utilisation and policy learning. I conclude this paper by elaborating on the corresponding future challenges that must be addressed before effective integration of sustainability indicators within policy systems can occur.

    Wegener, G.; Fruehwald, A.

    1994-01-01

    Forests as ecosystems not only supply the raw material wood but also exert an influence on soils, water resources and many other ecological factors; provide animals with a habitat; and offer as humans a place for recreation. Recently, forests and wood have become of interest to human civilisation from yet another aspect: they constitute a carbon storage. This means that forestry and the forest industries can help moderate the increase of atmospheric CO 2 concentrations, which is essentially the result of energetic utilisation of fossil fuels and considered the decisive factor underlying the greenhouse effect. Besides constituting a carbon storage, forests hold an additional CO 2 abatement potential which can be realised by continuous utilisation of wood. (orig./EF) [de

  1. Factor substitution, and economies of scale and utilisation in Kuwait's crude oil industry

    International Nuclear Information System (INIS)

    Al-Mutairi, Naief; Burney, Nadeem A.

    2002-01-01

    The cost structure of the crude oil industry in Kuwait has been examined, with specific focus on factor substitution, and economies of scale and utilisation. This has been done by estimating translog cost functions, both long-run and short-run, using time-series data covering the period from 1976 to 1996. The results indicate that the implied production structure is non-homothetic, and the pattern of scale effect is labour saving, but capital and material using. The evidence also supports the presence of an induced exogenous technical change, which is non-neutral (labour and capital using, and material saving). The elasticity of substitution between capital and labour is positive, implying that the two inputs are substitute. The results also indicate the existence of diseconomies of scale in the production of crude oil, but no economies or diseconomies of utilisation

  2. Combined centralised and distributed mechanism for utilisation of node association in broadband wireless network

    Science.gov (United States)

    Ulvan, A.; Ulvan, M.; Pranoto, H.

    2018-02-01

    Mobile broadband wireless access system has the stations that might be fixed, nomadic or mobile. Regarding the mobility, the node association procedure is critical for network entry as well as network re-entry during handover. The flexibility and utilisation of MAC protocols scheduling have an important role. The standard provides the Partition Scheme as the scheduling mechanism which separates the allocation of minislots for scheduling. However, minislots cannot be flexibly reserved for centralised and distributed scheduling. In this paper we analysed the scheduling mechanism to improve the utilisation of minislots allocation during the exchange of MAC massages. The centralised and distributed scheduling is implemented in some topology scenarios. The result shows the proposed mechanism has better performance for node association than partition scheme.

New challenges are faced with the growing amounts of municipal solid waste incineration bottom ash, which are mainly landfilled at the moment. Since this is not a sustainable or a profitable solution, finding different utilisation applications for the municipal solid waste incineration bottom ash is crucial. This study reports a comprehensive analysis of bottom ash properties from one waste incineration plant in Finland, which was first treated with a Dutch bottom ash recovery technique called advanced dry recovery. This novel process separates non-ferrous and ferrous metals from bottom ash, generating mineral fractions of different grain sizes (0-2 mm, 2-5 mm, 5-12 mm and 12-50 mm). The main aim of the study was to assess, whether the advanced bottom ash treatment technique, producing mineral fractions of different grain sizes and therefore properties, facilitates the utilisation of municipal solid waste incineration bottom ash in Finland. The results were encouraging; the bottom ash mineral fractions have favourable behaviour against the frost action, which is especially useful in the Finnish conditions. In addition, the leaching of most hazardous substances did not restrict the utilisation of bottom ash, especially for the larger fractions (>5 mm). Overall, this study has shown that the advanced bottom ash recovering technique can be one solution to increase the utilisation of bottom ash and furthermore decrease its landfilling in Finland. © The Author(s) 2015.

    Full Text Available Abstract Background Relatively little research attention has been given to the development of standardised and psychometrically sound scales for measuring influences relevant to the utilisation of health services. This study aims to describe the development, validation and internal reliability of some existing and new scales to measure factors that are likely to influence utilisation of preventive care services provided by general practitioners in Australia. Methods Relevant domains of influence were first identified from a literature review and formative research. Items were then generated by using and adapting previously developed scales and published findings from these. The new items and scales were pre-tested and qualitative feedback was obtained from a convenience sample of citizens from the community and a panel of experts. Principal Components Analyses (PCA and internal reliability testing (Cronbach's alpha were then conducted for all of the newly adapted or developed scales utilising data collected from a self-administered mailed survey sent to a randomly selected population-based sample of 381 individuals (response rate 65.6 per cent. Results The PCA identified five scales with acceptable levels of internal consistency were: (1 social support (ten items, alpha 0.86; (2 perceived interpersonal care (five items, alpha 0.87, (3 concerns about availability of health care and accessibility to health care (eight items, alpha 0.80, (4 value of good health (five items, alpha 0.79, and (5 attitudes towards health care (three items, alpha 0.75. Conclusion The five scales are suitable for further development and more widespread use in research aimed at understanding the determinants of preventive health services utilisation among adults in the general population.

    To examine variations between immigrants and nonimmigrants in 1) prevalence of common mental disorders and other mental health variables; 2) health service utilisation for emotional problems, mental disorders, and addictions, and 3) health service satisfaction. This article is based on a longitudinal cohort study conducted from May 2007 to the present: the Epidemiological Catchment Area Study of Montreal South-West (ZEPSOM). Participants were followed up at 4 time points (T1, n = 2433; T4, n = 1095). Core exposure variables include immigrant status (immigrant vs. nonimmigrant), duration of residence, and region of origin. Key outcome variables included mental health status, health service utilisation, and health service satisfaction. Data were analysed both cross-sectionally and longitudinally. Immigrants had been in Canada for 20 years on average. Immigrants had significantly lower rates of high psychological distress (32.6% vs. 39.1%, P = 0.016), alcohol dependence (1.4% vs. 3.9%, P =0.010), depression (5.2% vs. 9.2%, P = 0.008), and various other mental disorders. They had significantly higher scores of mental well-being (48.9 vs. 47.1 score, P = 0.014) and satisfaction with social (34.0 vs. 33.4 score, P = 0.021) and personal relationships (16.7 vs. 15.6 score, P Immigrants had significantly lower rates of health service utilisation for emotional problems, mental disorders, and addictions and significantly higher rates of health service satisfaction at all time points. Asian and African immigrants had particularly low rates of utilisation and high rates of satisfaction. Immigrants had better overall mental health than nonimmigrants.

  13. Increased utilisation of existing biogas plants; Oekat utnyttjande av befintliga biogasanlaeggningar

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, Mikael

    2007-09-15

    The purpose of this study is to analyse how existing biogas plants in Sweden could be utilised more efficiently, by increase the organic loading rate, and to calculate the cost efficiency of such measures. Biogas plants treating sewage sludge are currently operated with low organic loading rates and it is likely that there could be a considerable potential of increased utilisation of existing capacity. However, disposal costs of digested sewage sludge have a great impact on the economic result. Thus, the cost must be low, below 200 - 850 SEK/tonne DS, for co-digestion of sewage sludge and organic household waste to be economic competitive, compared to building of a new reactor. For co-digestion plants, using manure and organic waste as feedstock, it is not possible to say whether it is more economic to increase the utilisation of existing capacity or to increase the reactor volume. Therefore, more specific studies are required for individual plants and cases. Regarding the need for a more sophisticated monitoring and control of the biogas process, it can be established that the utilisation of sewage sludge digestion plants could be increased considerably without exceptionally high organic loading rates, thus probably without any additional monitoring and control. However, indicated prices for such applications are probably acceptable compared to establishing a new reactor. For co-digestion plants, the scope for investments is smaller and more dependent on the alternative cost for new reactors. Also, any process disturbances, which may appear even at low organic loading rates, could be very costly and result in costs in the same range as for monitoring and control equipment. Finally, the reader should observe that the analyses conducted here assume that funding and physical space for additional reactors is available at the existing site. If not, there could be situations where it is economic interesting to increase the organic loading rate although cost estimates

    The healthcare financing reforms initiated by the Government of Georgia in 2007 have positively affected inpatient service utilisation and enhanced financial protection, especially for the poor, but they have failed to facilitate outpatient service use among chronic patients. Non-communicable diseases significantly affect Georgia's ageing population. Consequently, in this paper, we look at the evidence emerging from determinants analysis of outpatient service utilisation and if the finding can help identify possible policy choices in Georgia, especially regarding benefit package design for individuals with chronic conditions. We used Andersen's behavioural model of health service utilisation to identify the critical determinants that affect outpatient service use. A multinomial logistic regression was carried out with complex survey design using the data from two nationally representative cross-sectional population-based health utilisation and expenditure surveys conducted in Georgia in 2007 and 2010, which allowed us to assess the relationship between the determinants and outpatient service use. The study revealed the determinants that significantly impede outpatient service use. Low income, 45- to 64-year-old Georgian males with low educational attainment and suffering from a chronic health problem have the lowest odds for service use compared to the rest of the population. Using Andersen's behavioural model and assessing the determinants of outpatient service use has the potential to inform possible policy responses, especially those driving services use among chronic patients. The possible policy responses include reducing financial access barriers with the help of public subsidies for sub-groups of the population with the lowest access to care; focusing/expanding state-funded benefits for the most prevalent chronic conditions, which are responsible for the greatest disease burden; or supporting chronic disease management programs for the most prevalent chronic

    This study investigates the impact of subsidising community-based health insurance (mutuelle) enrolment, removing point-of-service co-payments, and improving service delivery on health facility utilisation rates in Mayange, a sector of rural Rwanda of approximately 25,000 people divided among five ‘imidugudu’ or small villages. While comprehensive service upgrades were introduced in the Mayange Health Centre between April 2006 and February 2007, utilisation rates remained similar to comparison sites. Between February 2007 and April 2007, subsidies for mutuelle enrolment established virtually 100% coverage. Immediately after co-payments were eliminated in February 2007, patient visits levelled at a rate triple the previous value. Regression analyses using data from Mayange and two comparison sites indicate that removing financial barriers resulted in about 0.6 additional annual visits for curative care per capita. Although based on a single local pilot, these findings suggest that in order to achieve improved health outcomes, key short-term objectives include improved service delivery and reduced financial barriers. Based on this pilot, higher utilisation rates may be affected if broader swaths of the population are enrolled in mutuelle and co-payments are eliminated. Health leaders in Rwanda should consider further studies to determine if the impact of eliminating co-payments and increasing subsidies for mutuelle enrolment as seen in Mayange holds at greater levels of scale. Broader studies to better elucidate the impact of enrolment subsidies and co-payment subsidies on utilisation, health outcomes, and costs would also provide policy insights. PMID:21732708

    The Department of Correctional Services Policy on the management of HIV and AIDS for offenders include voluntary counselling and testing (VCT) for HIV as one of the priorities in the rehabilitation of inmates. The aim of this study was to determine factors associated with the utilisation of VCT services in the correctional centres in terms of level of satisfaction, their experiences and expectations, and motivating factors and barriers for VCT utilisation at Losperfontein Correctional Centre, South Africa. This was a case control study (cases being those who underwent testing and controls those who did not) examining predictors of HIV VCT utilisation among 200 male adult sentenced inmates serving medium and maximum sentences. Results indicate that a poor health system (OR=0.34, 95%CI: 0.23 - 0.50) was inversely associated with HIV testing acceptance in prison, while age, educational level, population group, marital status, length of incarceration and access to HIV testing in prison were not associated with HIV testing acceptance in prison. Half of the participants (50%) agreed that VCT services are accessible and are promoted at their correctional centre. Most were satisfied with different components of VCT services, ranging from 79% (fair to very good) for 'the way he/she received you' to 62% 'clarified all your concerns'. This study demonstrated some challenges and benefits to the field of health promotion and HIV prevention in the correctional centres especially with regard to VCT services.

    The health seeking behaviour of a community determines how they use health services. Utilisation of health facilities can be influenced by the cost of services, distance to health facilities, cultural beliefs, level of education and health facility inadequacies such as stock-out of drugs. To assess the health seeking practices and challenges in utilising health facilities in a rural community in Wakiso district, Uganda. The study was a cross sectional survey that used a structured questionnaire to collect quantitative data among 234 participants. The sample size was obtained using the formula by Leslie Kish. While 89% of the participants were aware that mobile clinics existed in their community, only 28% had received such services in the past month. The majority of participants (84%) did not know whether community health workers existed in their community. The participants' health seeking behaviour the last time they were sick was associated with age (p = 0.028) and occupation (p = 0.009). The most significant challenges in utilising health services were regular stock-out of drugs, high cost of services and long distance to health facilities. There is potential to increase access to health care in rural areas by increasing the frequency of mobile clinic services and strengthening the community health worker strategy.

The objective of this study was to evaluate the utilisation of podiatry services provided under this scheme between 2004 and 2008. Methods Data pertaining to the Medicare item 10962 for the calendar years 2004-2008 were extracted from the Australian Medicare Benefits Schedule (MBS database and cross-tabulated by sex and age. Descriptive analyses were undertaken to assess sex and age differences in the number of consultations provided and to assess for temporal trends over the five-year assessment period. The total cost to Medicare over this period was also determined. Results During the 2004-2008 period, a total of 1,338,044 EPC consultations were provided by podiatrists in Australia. Females exhibited higher utilisation than males (63 versus 37%, and those aged over 65 years accounted for 75% of consultations. There was a marked increase in the number of consultations provided from 2004 to 2008, and the total cost of providing EPC podiatry services during this period was $62.9 M. Conclusion Podiatry services have been extensively utilised under the EPC program by primary care patients, particularly older women, and the number of services provided has increased dramatically between 2004 and 2008. Further research is required to determine whether the EPC program enhances clinical outcomes compared to standard practice.

    There are thousands of medical applications for mobile devices targeting use by healthcare professionals. However, several factors related to the structure of the existing market for medical applications create significant barriers preventing practitioners from effectively identifying mobile medical applications for individual professional use. To define existing market factors relevant to selection of medical applications and describe a framework to empower clinicians to identify, assess and utilise mobile medical applications in their own practice. Resources available on the Internet regarding mobile medical applications, guidelines and published research on mobile medical applications. Mobile application stores (e.g. iTunes, Google Play) are not effective means of identifying mobile medical applications. Users of mobile devices that desire to implement mobile medical applications into practice need to carefully assess individual applications prior to utilisation. Searching and identifying mobile medical applications requires clinicians to utilise multiple references to determine what application is best for their individual practice methods. This can be done with a cursory exploration of mobile application stores and then moving onto other available resources published in the literature or through Internet resources (e.g. blogs, medical websites, social media). Clinicians must also take steps to ensure that an identified mobile application can be integrated into practice after carefully reviewing it themselves. Clinicians seeking to identify mobile medical application for use in their individual practice should use a combination of app stores, published literature, web-based resources, and personal review to ensure safe and appropriate use. © 2014 John Wiley & Sons Ltd.

    This thesis investigated the properties of bottom and fly ashes originating from a bubbling fluidised bed boiler (120 MW) using two different fuel mixtures (i.e. Fuel mixture A: coal, wood and peat; and B: wood and peat) and of the green liquor dregs originating from the associated semichemical pulp and board mill in relation to the potential utilisation of these residues from various aspects. The total concentrations of As, Cd, Cr, Cu, Ni, Pb, Zn and Hg in the bottom ashes were lower than the maximum allowable concentrations for these elements in forest fertilisers. The total Ca concentrations in bottom ashes A (2.4%; d.w.) and B (3.4%; d.w.) were lower than the legal requirement of 6.0% (d.w.) for ash used as a forest fertiliser. The total Ca concentrations in fly ashes A (6.4%; d.w.) and B (11.0%; d.w.) were higher than the minimum limit value of 6.0% (d.w.), but the concentration of As in fly ashes A (46.9 mg/kg d.w.) and B (41.3 mg/kg; d.w.) exceeded the maximum limit value of 40 mg/kg (d.w.). Only bottom ash B could be used as a forest fertiliser, provided some additional Ca is used. The bottom ashes both fulfilled the Finnish regulations on waste recovery in earth construction. Due to the elevated total concentration of PAH (23 mg/kg; d.w.) and extractable concentrations of Mo (3.9 mg/kg; d.w.) and Se (0.2 mg/kg; d.w.) in fly ash A, this residue cannot be used in covered structures. Due to the elevated concentration of PAH (90 mg/kg; d.w.) in fly ash B, this residue cannot be used in covered and paved structures. However, the utilisation of these residues as an earth construction agent is still possible, but an environmental permit would be required. According to the sequential extraction studies, extractable concentrations of most of the elements in the fly ash A were higher than those in the bottom ash A. The extractability of various elements, both in the bottom and fly ashes A, varied widely. Most of the elements did not occur as readily soluble and

    The general purpose neutron-photon-electron Monte Carlo N-Particle code, MCNP TM , has been used to simulate the neutronic characteristics of the on-site laboratory passive neutron coincidence counter to be installed, under Euratom Safeguards Directorate supervision, at the Sellafield reprocessing plant in Cumbria, UK. This detector is part of a series of nondestructive assay instruments to be installed for the accurate determination of the plutonium content of nuclear materials. The present work focuses on one aspect of this task, namely, the accurate calculation of the coincidence gate utilisation factor. This parameter is an important term in the interpretative model used to analyse the passive neutron coincidence count data acquired using pulse train deconvolution electronics based on the shift register technique. It accounts for the limited proportion of neutrons detected within the time interval for which the electronics gate is open. The Monte Carlo code MCF, presented in this work, represents a new evaluation technique for the estimation of gate utilisation factors. It uses the die-away profile of a neutron coincidence chamber generated either by MCNP TM , or by other means, to simulate the neutron detection arrival time pattern originating from independent spontaneous fission events. A shift register simulation algorithm, embedded in the MCF code, then calculates the coincidence counts scored within the electronics gate. The gate utilisation factor is then deduced by dividing the coincidence counts obtained with that obtained in the same Monte Carlo run, but for an ideal detection system with a coincidence gate utilisation factor equal to unity. The MCF code has been benchmarked against analytical results calculated for both single and double exponential die-away profiles. These results are presented along with the development of the closed form algebraic expressions for the two cases. Results of this validity check showed very good agreement. On this

    In its amended form the German Household Waste Technical Code favours physical and thermal utilisation of wastes against dumping. Industrial processes offer various ways of utilising wastes with a high calorific value, e.g. in nonferrous metal production. Besides portraying this branch of industry in Germany the present paper investigates to what extent this topic has already found coverage and what potential it holds for the utilisation of wastes. By way of example it describes a successful demonstration of the physical utilisation of sewage sludge in lead production. [Deutsch] Die Neugestaltung der TA Siedlungsabfall favorisiert die thermische und stoffliche Verwertung von Abfallstoffen gegenueber der Deponierung. Moeglichkeiten fuer die Verwertung heizwertreicher Abfaelle bieten auch industrielle Produktionsprozesse, z.B. auch in der Nichteisenmetallerzeugung. Neben einer Charakterisierung der Branche wird untersucht, inwieweit dieses Thema bereits aufgegriffen worden ist und welches Verwertungspotential zur Verfuegung steht.

    Various studies have reported that university students, who are mostly young people, rarely use existing HIV/AIDS preventive methods. Although studies have shown that young university students have a high degree of knowledge about HIV/AIDS and HIV modes of transmission, they are still not utilising the existing HIV prevention methods and still engage in risky sexual practices favourable to HIV. Some variables, such as awareness of existing HIV/AIDS prevention methods, have been associated with utilisation of such methods. The study aimed to explore factors that influence use of existing HIV/AIDS prevention methods among university students residing in a selected campus, using the Health Belief Model (HBM) as a theoretical framework. A quantitative research approach and an exploratory-descriptive design were used to describe perceived factors that influence utilisation by university students of HIV/AIDS prevention methods. A total of 335 students completed online and manual questionnaires. Study findings showed that the factors which influenced utilisation of HIV/AIDS prevention methods were mainly determined by awareness of the existing university-based HIV/AIDS prevention strategies. Most utilised prevention methods were voluntary counselling and testing services and free condoms. Perceived susceptibility and perceived threat of HIV/AIDS score was also found to correlate with HIV risk index score. Perceived susceptibility and perceived threat of HIV/AIDS showed correlation with self-efficacy on condoms and their utilisation. Most HBM variables were not predictors of utilisation of HIV/AIDS prevention methods among students. Intervention aiming to improve the utilisation of HIV/AIDS prevention methods among students at the selected university should focus on removing identified barriers, promoting HIV/AIDS prevention services and providing appropriate resources to implement such programmes.

    Prenatal health care is pivotal in providing adequate prevention and care to pregnant women. We examined the determinants of inadequate prenatal health care utilisation by low-risk women in primary midwifery-led care in the Netherlands. We used longitudinal data from the population-based DELIVER study with 20 midwifery practices across the Netherlands in 2009 and 2010 as the experimental setting. The participants were 3070 pregnant women starting pregnancy care in primary midwifery care. We collected patient-reported data on potential determinants of prenatal care utilisation derived from the Andersen model. Prenatal health care utilisation was measured by a revised version of the Kotelchuck Index, which measures a combination of care entry and number of visits. Low-risk pregnant women (not referred during pregnancy) were more likely to use prenatal care inadequately if they intended to deliver at a hospital, if they did not use folic acid adequately periconceptionally, or if they were exposed to cigarette smoke during pregnancy. Among those who were referred to secondary care, women reporting a chronic illnesses or disabilities, and women who did not use folic acid periconceptionally were more likely to make inadequate use of prenatal care. Inadequate prenatal health care use in primary midwifery care is more likely in specific groups, and the risk groups differ when women are referred to secondary care. The findings suggest routes that can target interventions to women who are at risk of not adequately using prenatal prevention and care services. Copyright © 2015 Australian College of Midwives.

    Full Text Available Background: Malawi provides cervical cancer screening services free of charge at some public health facilities. Few women make use of these cancer screening services in Malawi and many women continue to be diagnosed with cervical cancer only during the late inoperable stages of the condition. Objectives: The purpose of this study was to discover whether the perceived susceptibility to cervical cancer, amongst Malawian women aged 42 and older, influenced their intentions to utilise the available free cervical cancer screening services. Method: A quantitative, cross-sectional descriptive study design was adopted. Structured interviews were conducted with 381 women who visited 3 health centres in the Blantyre District of Malawi. Results: A statistically-significant association existed between women’s intentions to be screened for cervical cancer and their knowledge about cervical cancer (X² = 8.9; df = 1; p = 0.003 and with having heard about HPV infection (X² = 4.2; df = 1; p = 0.041 at the 5% significance level. Cervical cancer screening services are provided free of charge in government health institutions in Malawi. Nevertheless, low perceived susceptibility to cervical cancer amongst women, aged 42 and older, might contribute to limited utilisation of cervical screening services, explaining why 80% of cervical cancer patients in Malawi were diagnosed during the late inoperable stages. Conclusion: Malawian women lacked awareness regarding their susceptibility to cervical cancer and required information about the available cervical cancer screening services. Malawi’s women, aged 42 and older, must be informed about the advantages of cervical cancer screening and about the importance of effective treatment if an early diagnosis has been made. Women aged 42 and older rarely attend antenatal, post-natal, well baby or family-planning clinics, where health education about cervical cancer screening is often provided. Consequently, these women

    Underutilisation of radiotherapy has been observed worldwide. To evaluate the current situation in Belgium, optimal utilisation proportions (OUPs) adopted from the European SocieTy for Radiotherapy and Oncology - Health Economics in Radiation Oncology (ESTRO-HERO) project were compared to actual utilisation proportions (AUPs) and with radiotherapy advised during the multidisciplinary cancer team (MDT) meetings. In addition, the impact of independent variables was analysed. AUPs and advised radiotherapy were calculated overall and by cancer type for 110,810 unique cancer diagnoses in 2009-2010. Radiotherapy utilisation was derived from reimbursement data and distinguished between palliative and curative intent external beam radiotherapy (EBRT) and/or brachytherapy (BT). Sensitivity analyses regarding the influence of the follow-up period, the survival length and patient's age were performed. Advised radiotherapy was calculated based on broad treatment categories as reported at MDT meetings. The overall AUP of 37% (39% including BT) was lower than the OUP of 53%, but in line with advised radiotherapy (35%). Large variations by tumour type were observed: in some tumours (e.g. lung and prostate cancer) AUP was considerably lower than OUP, whereas in others there was reasonable concordance (e.g. breast and rectal cancer). Overall, 84% of treatments started within 9 months following diagnosis. Survival time influenced AUP in a cancer type-dependent way. Elderly patients received less radiotherapy. Although the actually delivered radiotherapy in Belgium aligns well to MDT advices, it is lower than the evidence-based optimum. Further analysis of potential barriers is needed for radiotherapy forecasting and planning, and in order to promote adequate access to radiotherapy. Copyright © 2017 Elsevier Ltd.

    Highlights: • It is attempted to provide critical considerations on various biogas upgrading techniques. • Membrane is an environmentally and economically sound technique for purification. • Purified biogas in compressed form is a substitute of compressed natural gas for vehicles. • Charged mass and compressor input work are the most important factors for storage. - Abstract: Biogas upgrading is a widely studied and discussed topic and its utilisation as a natural gas substitute has gained a significant attention in recent years. The production of biomethane provides a versatile application in both heat and power generation and as a vehicular fuel. This paper systematically reviews the state of the art of biogas upgrading technologies with upgrading efficiency, methane (CH 4 ) loss, environmental effect, development and commercialisation, and challenges in terms of energy consumption and economic assessment. The market situation for biogas upgrading has changed rapidly in recent years, making the membrane separation gets significant market share with traditional biogas upgrading technologies. In addition, the potential utilisation of biogas, efficient conversion into bio-compressed natural gas (bio-CNG), and storage systems are investigated in depth. Two storing systems for bio-CNG at filling stations, namely buffer and cascade storage systems are used. The best storage system should be selected on the basis of the advantages of both systems. Also, the fuel economy and mass emissions for bio-CNG and CNG filled vehicles are studied. There is the same fuel economy and less carbon dioxide (CO 2 ) emission for bio-CNG. Based on the results of comparisons between the technical features of upgrading technologies, various specific requirements for biogas utilisation and the relevant investment, and operating and maintenance costs, future recommendations are made for biogas upgrading.

    Homelessness status is strongly correlated with higher rates of substance use. Few studies, however, examine the complex relationship between housing status and substance use in people who inject drugs (PWID). This study extends previous research by comparing the physical and mental health status and service utilisation rates between stably housed and homeless PWID. A cross-sectional sample of 923 PWID were recruited for the 2012 Illicit Drug Reporting System. Multivariate models were generated addressing associations between homelessness and the domains of demographics; substance use; and health status, service utilisation and criminal justice system contact, with significant correlates entered into a final multivariate model. Two-thirds of the PWID sample were male. The median age was 39 years and 16% identified as Indigenous. Almost one-quarter (23%) reported that they were homeless. Homeless PWID were significantly more likely to be unemployed [adjusted odds ratio (AOR) 2.83, 95% confidence interval (CI) 1.26, 6.34], inject in public (AOR 2.01, 95% CI 1.38, 3.18), have poorer mental health (AOR 0.98, 95% CI 0.97, 1.00), report schizophrenia (AOR 2.31, 95% CI 1.16, 4.60) and have a prison history (AOR 1.53, 95% CI 1.05, 2.21) than stably housed PWID. Findings highlight the challenge of mental health problems for homeless PWID. Our results demonstrate that further research that evaluates outcomes of housing programs accommodating PWID, particularly those with comorbid mental health disorders, is warranted. Results also emphasise the need to better utilise integrated models of outreach care that co-manage housing and mental health needs. © 2015 Australasian Professional Society on Alcohol and other Drugs.

    Full Text Available Abstract Background There is a need to review factors related to health service utilisation by the increasing number of cancer survivors in order to inform care planning and the organisation and delivery of services. Methods Studies were identified via systematic searches of Medline, PsycINFO, CINAHL, Social Science Citation Index and the SEER-MEDICARE library. Methodological quality was assessed using STROBE; and the Andersen Behavioural Model was used as a framework to structure, organise and analyse the results of the review. Results Younger, white cancer survivors were most likely to receive follow-up screening, preventive care, visit their physician, utilise professional mental health services and least likely to be hospitalised. Utilisation rates of other health professionals such as physiotherapists were low. Only studies of health service use conducted in the USA investigated the role of type of health insurance and ethnicity. There appeared to be disparate service use among US samples in terms of ethnicity and socio-demographic status, regardless of type of health insurance provision s- this may be explained by underlying differences in health-seeking behaviours. Overall, use of follow-up care appeared to be lower than expected and barriers existed for particular groups of cancer survivors. Conclusions Studies focussed on the use of a specific type of service rather than adopting a whole-system approach and future health services research should address this shortcoming. Overall, there is a need to improve access to care for all cancer survivors. Studies were predominantly US-based focussing mainly on breast or colorectal cancer. Thus, the generalisability of findings to other health-care systems and cancer sites is unclear. The Andersen Behavioural Model provided an appropriate framework for studying and understanding health service use among cancer survivors. The active involvement of physicians and use of personalised care plans are

    To examine the association between socio-economic status (SES) and GP utilisation across Statistical Local Areas (SLAs) that differed in their geographic remoteness, and to assess whether Indigenous status and GP availability modified the association. Retrospective analysis of Medicare data for all unreferred GP consultations (1996/97) for 952 SLAs comprising the six Australian States. Geographic remoteness was ascertained using the Area Remoteness Index of Australia (ARIA), and SES was measured by grouping SLAs into tertiles based on their Index of Relative Socioeconomic Disadvantage score. Age/sex standardised rates of GP utilisation for each SLA. In SLAs classified as 'highly accessible', rates of GP use were 10.8% higher (95% CI 5.7-16.0) in the most socio-economically disadvantaged tertile after adjustment for Indigenous status and GP availability. A very different pattern of GP utilsation was found in 'remote/very remote' SLAs. After adjustment, rates of GP use in the most socio-economically disadvantaged tertile were 25.3% lower (95% CI 5.9-40.7) than in the most advantaged tertile. People in socio-economically disadvantaged metropolitan SLAs have higher rates of GP utilisation, as would be expected due to their poorer health. This is not true for people living in disadvantaged remote/very remote SLAs: in these areas, those most in need of GP services are least likely to receive them. Australia may lay claim to having a primary health care system that provides universal coverage, but we are still some way from having a system that is economically and geographically accessible to all.

    2013-01-01

    Malaysia is the world′s second largest producer of palm oil and generates surplus palm biomass waste that can be used for bioenergy development. Malaysia aims to diversify its energy portfolio by investing into renewable energy mostly to reduce its reliance on fossil fuels. This paper captures synergetic and conflicting interests of key stakeholders, who play an important role in shaping the regulatory and business environment in Malaysia′s renewable energy sector. Particularly, this research analyses the perceptions of three stakeholder groups (government agencies, industry players, and non-governmental organisations) regarding palm-based biofuel and biomass utilisation in Malaysia by combining Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis with an Analytical Hierarchy Process (AHP) framework. Overall, results show a greater sense of optimism among the three stakeholder groups for the development of palm-based biomass utilisation in Malaysia, compared to the development of first generation palm-oil based biodiesel. We discuss the findings in light of on-going debates and policy processes, highlighting some key issues that need to be addressed in order to meet oil-palm related targets set in Malaysia’s ambitious renewable energy plan. - Highlights: • Optimism of stakeholders is greater for palm biomass utilisation than palm biodiesel. • The negative overall outlook for palm biodiesel is perhaps a symptom of hindsight. • Palm biodiesel: strengths (18%), weaknesses (34%), opportunities (23%), and threats (25%). • Palm biomass: strengths (42%), weaknesses (23%), opportunities (15%), and threats (21%). • Views of stakeholder groups are relevant to meeting Malaysia´s renewables target

    Full Text Available Background: Infection with the Hepatitis C Virus (HCV is a widespread transmittable disease with a diagnosed prevalence of 2.0%. Fortunately, it is now curable in most patients. Sales of medicines to treat HCV infection grew 2.7% per year between 2004 and 2011, enhanced by the launch of the protease inhibitors (PIs boceprevir (BCV and telaprevir (TVR in addition to ribavirin and pegylated interferon (pegIFN. Costs will continue to rise with new treatments including sofosbuvir, which now include interferon free regimens. Objective: Assess the uptake of BCV and TVR across Europe from a health authority perspective to offer future guidance on dealing with new high cost medicines. Methods: Cross-sectional descriptive study of medicines to treat HCV (pegIFN, ribavirin, BCV and TVR among European countries from 2008 to 2013. Utilisation measured in defined daily doses (DDDs/ 1000 patients/ quarter (DIQs and expenditure in Euros/ DDD. Health authority activities to influence treatments categorised using the 4E methodology (Education, Engineering, Economics and Enforcement. Results: Similar uptake of BCV and TVR among European countries and regions, ranging from 0.5 DIQ in Denmark, Netherlands and Slovenia to 1.5 DIQ in Tayside and Catalonia in 2013. However, different utilisation of the new PIs versus ribavirin indicates differences in dual versus triple therapy, which is down to factors including physician preference and genotypes. Reimbursed prices for BCV and TVR were comparable across countries. Conclusion: There was reasonable consistency in the utilisation of BCV and TVR among European countries in comparison with other high priced medicines. This may reflect the social demand to limit the transmission of HCV. However, the situation is changing with new curative medicines for HCV genotype 1 (GT1 with potentially an appreciable budget impact. These concerns have resulted in different prices negotiations across countries, with their impact

  10. Rational bioenergy utilisation in energy systems and impacts on CO{sub 2} emissions

    The increased use of biomass in energy systems is an important strategy to reduce CO{sub 2} emissions. The purpose of this thesis has been to analyse the opportunities for Sweden to further reduce CO{sub 2} emissions in the energy system, by rationally utilising woody biomass energy. The characteristics of current commercially operating biofuel-based CHP plants in Sweden are surveyed and systematically presented. A consistent and transparent comprehensive reference base for system comparisons is given. Furthermore, the fuel effectiveness and contribution to CO{sub 2} reduction is calculated. The governmental subsidies of the CHP plants investment, expressed as cost of specific CO{sub 2} reduction, appears to be low. The competitiveness of biomass-fuelled energy production in relation to fossil-based production with carbon capture is analysed, showing that the biomass-fuelled systems provide a competitive option, in terms of cost of electricity and efficiencies. The remaining Swedish woody biofuel potential of at least 100 PJ/yr is principally available in regions with a biomass surplus. Transportation is therefore required to enable its utilisation in national and international markets. Refining the biofuel feedstock to pellets, or even further refining to motor fuels (DME, methanol or ethanol) or power, could facilitate this transport. Different options for fuel refining are studied and compared. The entire fuel chain, from fuel feedstock to end users, is considered and CO{sub 2} emissions are quantified. Substituting fuel pellets for coal appears to be the most cost effective alternative and shows the largest CO{sub 2} reduction per energy unit biofuel. Motor fuels appear more costly and give about half the CO{sub 2} reduction. Transportation of the upgraded biofuel pellets is highly feasible from CO{sub 2} emissions point of view and does not constitute a hindrance for further utilisation, i.e. the pellets can be transported over long distances efficiently with

    Full Text Available SMEs contribute considerably to the national GDP and to private sector employment, but they struggle to gain access to the funding needed to support business sustainability and growth. Venture capital provides the necessary funding, but SMEs lack understanding of the business value curve utilised by financiers to gauge the risk-reward characteristics of an investment. Strategies need to convey how the business model will evolve in order to deliver on the strategic intent. A framework is proposed through which SMEs can develop a strategy aligned with investor requirements. As a case study, the framework is applied to the local tooling sector.

    BACKGROUND: Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context. METHODS: Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety\\/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications. RESULTS: Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2-17.9) and depression\\/anxiety (OR 5.8, 95% CI: 2.2-15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3-12.7; OR 3.4, 95% CI: 1.2-10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1-11.9; OR 3.3, 95% CI: 1.0-10.4) or post migration stressors (OR 17.3, 95% CI: 4.9-60.8; OR 3.9, 95% CI: 1.2-12.3) were independent predictors of self reported PTSD or depression\\/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression\\/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (chi2 = 19.74, df = 1, P < 0.001).In terms of health care utilisation, asylum seekers use GP services more often than refugees, while no significant difference was found between these groups

    Postnatal care (PNC) in the first seven days is important for preventing morbidity and mortality in mothers and new-borns. Sub-Saharan African countries, which account for 62 % of maternal deaths globally, have made major efforts to increase PNC utilisation, but utilisation rates remains low even in countries like Rwanda where PNC services are universally available for free. This study identifies key socio-economic and demographic factors associated with PNC utilisation in Rwanda to inform improved PNC policies and programs. This is a secondary analysis of the 2010 Demographic and Health Survey, a national multi-stage, cross-sectional survey. In bivariate analysis, we used chi-square tests to identify demographic and socio-economic factors associated with PNC utilisation at α = 0.1. Pearson's R statistic (r > 0.5) was used to identify collinear covariates, and to choose which covariate was more strongly associated with PNC utilisation. Manual backward stepwise logistic regression was performed on the remaining covariates to identify key factors associated with PNC utilisation at α = 0.05. All analyses were performed in Stata 13 adjusting for sampling weights, clustering, and stratification. Of the 2,748 women with a live birth in the last two years who answered question about PNC utilisation, 353 (12.8 %) returned for PNC services within seven days after birth. Three factors were positively associated with PNC use: delivering at a health facility (OR: 2.97; 95 % CI: 2.28-3.87), being married but not involved with one's own health care decision-making (OR: 1.69; 95 % CI: 1.17, 2.44) compared to being married and involved; and being in the second (OR: 1.46; 95 % CI: 1.01-2.09) or richest wealth quintile (OR: 2.04; 95 % CI: 1.27-3.29) compared to the poorest. Mother's older age at delivery was negatively associated with PNC use (20-29 - OR: 0.51, 95 % CI: 0.29-0.87; 30-39 - OR: 0.47, 95 % CI: 0.27-0.83; 40-49 - OR: 0.32, 95 % CI: 0.16-0.64). Low PNC

    In order to alleviate the problem of "Kan Bing Nan, Kan Bing Gui" (medical treatment is difficult to access and expensive) and improve the equity of health service utilisation for urban residents in China, the Urban Employee Basic Medical Insurance scheme (UEBMI) and Urban Resident Basic Medical Insurance scheme (URBMI) were established in 1999 and 2007, respectively. This study aims to analyse the effects of UEBMI and URBMI on the equity of outpatient and inpatient utilisation in Shaanxi Province, China. Using the data from the fourth National Health Services Survey in Shaanxi Province, the method of Propensity Score Matching was employed to generate comparable samples between the insured and uninsured residents, through a one-to-one match algorithm. Next, based on the matched data, the method of decomposition of the concentration index was employed to compare the horizontal inequity indexes of health service utilisation between the UEBMI/URBMI insured and the matched uninsured residents. For the UEBMI insured and matched uninsured residents, the horizontal inequity indexes of outpatient visits are 0.1256 and -0.0511 respectively, and the horizontal inequity indexes of inpatient visits are 0.1222 and 0.2746 respectively. Meanwhile, the horizontal inequity indexes of outpatient visits are -0.1593 and 0.0967 for the URBMI insured and matched uninsured residents, and the horizontal inequity indexes of inpatient visits are 0.1931 and 0.3199 respectively. The implementation of UEBMI increased the pro-rich inequity of outpatient utilisation (rich people utilise outpatient facilities more than the poor people) and the implementation of URBMI increased the pro-poor inequity of outpatient utilisation. Both of these two health insurance schemes reduced the pro-rich inequity of inpatient utilisation.

    There is wide variation in the proportion of newly diagnosed cancer patients who receive chemotherapy, indicating the need for a benchmark rate of chemotherapy utilisation. This study describes an evidence-based model that estimates the proportion of new cancer patients in whom chemotherapy is indicated at least once (defined as the optimal chemotherapy utilisation rate). The optimal chemotherapy utilisation rate can act as a benchmark for measuring and improving the quality of care. Models of optimal chemotherapy utilisation were constructed for each cancer site based on indications for chemotherapy identified from evidence-based treatment guidelines. Data on the proportion of patient- and tumour-related attributes for which chemotherapy was indicated were obtained, using population-based data where possible. Treatment indications and epidemiological data were merged to calculate the optimal chemotherapy utilisation rate. Monte Carlo simulations and sensitivity analyses were used to assess the effect of controversial chemotherapy indications and variations in epidemiological data on our model. Chemotherapy is indicated at least once in 49.1% (95% confidence interval 48.8-49.6%) of all new cancer patients in Australia. The optimal chemotherapy utilisation rates for individual tumour sites ranged from a low of 13% in thyroid cancers to a high of 94% in myeloma. The optimal chemotherapy utilisation rate can serve as a benchmark for planning chemotherapy services on a population basis. The model can be used to evaluate service delivery by comparing the benchmark rate with patterns of care data. The overall estimate for other countries can be obtained by substituting the relevant distribution of cancer types. It can also be used to predict future chemotherapy workload and can be easily modified to take into account future changes in cancer incidence, presentation stage or chemotherapy indications.

    A headspace gas chromatography (HSGC) method was developed for the determination of water content in honey. This method was shown to work with five different honey varieties which had a range of water from 14-16%. It also utilised two different detectors, the thermal conductivity detector (TCD) and the barrier discharge ionisation detector (BID). This method needs no heating pretreatment step as in the current leading method, (i.e. the measurement of refractive index). The solvent-free procedure negates the possibility of solvent-compound interactions as well as solubility limitations, as is common with Karl Fischer titrations. It was also apparent that the classic loss on drying method consistently and substantially produced results that were lower than the correct values. This approach is shown to be rapid, with an analysis time of 4 min when using the TCD detector and under 3 min when utilising the BID detector. HSGC is feasible for the determination of water due to the new PEG-linked geminal dicationic ionic-liquid-coated GC capillary column. In addition it provides accurate and precise determinations of the water content in honey. When using the sensitive BID detector, other trace volatile compounds are observed as well.

    Full Text Available Every year thousands of core families disintegrate through divorce, and in the ensuing restructuring of the family system the child has to cope with various development challenges, such as divided membership of two micro family systems and complexities that result at the mesosystemic level. Achieving positive development outcomes in the presence of challenging living circumstances entails complex interactive processes. The aim of the study was to understand the concomitant, reciprocal and/or responsive dynamics of middle adolescents' use of their inherent resilience potential in their movement back and forth between their two reconstituted family systems after the parents' divorce. The study was grounded in the qualitative interpretivist paradigm, and used a multiple case study as research design and a narrative format for description. A purposive sample of four white Afrikaans-speaking middle adolescents participated in the research. Findings revealed that middle adolescents of divorced parents utilise their resilience potential in a systemic manner, which requires a solid base provided by the meso system. Hence the utilisation of resilience relies at the very minimum on a functional relationship of cooperation between the biological parents.

  4. Access and utilisation of maternity care for disabled women who experience domestic abuse: a systematic review

    2014-01-01

    Background Although disabled women are significantly more likely to experience domestic abuse during pregnancy than non-disabled women, very little is known about how maternity care access and utilisation is affected by the co-existence of disability and domestic abuse. This systematic review of the literature explored how domestic abuse impacts upon disabled women’s access to maternity services. Methods Eleven articles were identified through a search of six electronic databases and data were analysed to identify: the factors that facilitate or compromise access to care; the consequences of inadequate care for pregnant women’s health and wellbeing; and the effectiveness of existing strategies for improvement. Results Findings indicate that a mental health diagnosis, poor relationships with health professionals and environmental barriers can compromise women’s utilisation of maternity services. Domestic abuse can both compromise, and catalyse, access to services and social support is a positive factor when accessing care. Delayed and inadequate care has adverse effects on women’s physical and psychological health, however further research is required to fully explore the nature and extent of these consequences. Only one study identified strategies currently being used to improve access to services for disabled women experiencing abuse. Conclusions Based upon the barriers and facilitators identified within the review, we suggest that future strategies for improvement should focus on: understanding women’s reasons for accessing care; fostering positive relationships; being women-centred; promoting environmental accessibility; and improving the strength of the evidence base.

    To describe the self-reported health status and service utilisation of employed, retired and unemployed migrants in Guangzhou, a megacity in southern China. A cross-sectional study adapted from the National Health Service Survey was conducted between September and December in 2014. Based on the distribution of occupation of migrants, multistage sampling was used to recruit individuals. Logistic regression was applied to explore the factors influencing their service utilisation. Of 2906 respondents, 76.6% were employed, 9.2% retired and 14.2% unemployed. Only 8.1% reported having an illness in the previous 2 weeks, and 6.5% reported having been hospitalised in the previous year. Employed migrants had the lowest recent physician consultation rate (3.4%) and the lowest annual hospitalisation rate (4.5%) (P rates (6.8% and 14.5% respectively, P employed (1.5%) and unemployed migrants (3.4%) (P gender, employment status remained significant in explaining the recent two-week treatment-seeking behaviour of migrants (P Employed migrants make the least use of health services. © 2016 John Wiley & Sons Ltd.

    Full Text Available Generation Z was the foremost generation to have prevalent access to the Internet from an early age. Technology has strongly influenced this generation in terms of communication, education and consequently their academic information behaviour. With the next generation of scholars already being trained, in a decade, most of the researchers will be mainly digital natives. This study sought to establish the library information resources use pattern in relation to users’ preferred information media in order to render better academic information services to library users. A total of 390 respondents were surveyed at the Nelson Mandela University and the University of Fort Hare using quantitative and qualitative methods. Most of the respondents, 82.3%, were aged between 18 and 23 years; while the average library use time was two hours daily. The most utilised library resource is the Wi-Fi with e-books and e-journals found to be lowly utilised. Records from the E-librarians revealed that undergraduate students account for no more than 6% of total users of electronic databases with 62.3% of the respondents preferring print information resources. Better understanding of library users’ demographics and information media preference is essential in proving the right kind of information services to Generation Z library users.

  7. Utilisation of information technology to support information and knowledge management by lawyers in Polokwane City

    2010-01-01

    Full Text Available A revolution in information and communication technology is taking place in the world. With this technological revolution, information and knowledge are also considered as crucial assets for every organization. Law firms are regarded as one of the industries which are information and knowledge-intensive. The utilization of information technology can play an essential role in supporting information and knowledge management in law firms. An investigation into the extent to which lawyers or law firms in Polokwane city utilize information technology to support information and knowledge management was conducted through a survey questionnaire based on the Technology Acceptance Model. The findings of this research showed that lawyers utilise information technology systems or applications that are common, such as word processing, e-mail, client billing and online databases for searching legal information. Other information and knowledge management tools, such as Intranets, extranets and web portals, were the least and non-utilised applications by these lawyers. The main reason for non-utilization of such systems may be linked to non- exposure to information technology and unfamiliarity with information and knowledge management tools. It is, therefore, recommended that legal schools should include, in their curriculum, modules on the application and role of information technology in the legal practice. Recommendations for future research related to this subject are also provided.

    2005-10-01

    This paper uses the concept of sustainable development to examine the utilisation of wildlife resources at Moremi Game Reserve (MGR) and Khwai community area (NG 18/19) in the Okavango Delta, Botswana. Using both secondary and primary data sources, results show that the establishment of MGR in 1963 led to the displacement of Khwai residents from their land; affected Basarwa's hunting and gathering economy; marked the beginning of resource conflicts between Khwai residents and wildlife managers; and, led to the development of negative attitudes of Khwai residents towards wildlife conservation. Since the late 1980s, a predominantly foreign owned tourism industry developed in and around MGR, however, Khwai residents derive insignificant benefits from it and hence resource conflicts increased. In an attempt to address problems of resource conflicts and promote sustainable wildlife utilisation, the Botswana Government adopted the Community-Based Natural Resource Management (CBNRM) programme, which started operating at Khwai village in 2000. The CBNRM programme promotes local participation in natural resource management and rural development through tourism. It is beginning to have benefits to Khwai residents such as income generation, employment opportunities and local participation in wildlife management. These benefits from CBNRM are thus having an impact in the development of positive attitudes of Khwai residents towards wildlife conservation and tourism development. This paper argues that if extended to MGR, CBNRM has the potential of minimising wildlife conflicts between Khwai residents and the wildlife-tourism sectors. This approach may in the process promote the sustainable wildlife use in and around MGR.

    This paper describes the results obtained while testing the technical feasibility of using oleic sunflower methyl ester (SME) blended with Diesel fuel in proportions up to 30% in an unmodified Diesel bus engine. Vegetable oils methyl esters blended with Diesel oil are commonly used in compression ignition engines. However, R and D background information on the practical use of traditional sunflower oil derivatives is sparse. The present results include evaluation of the engine performance and fuel consumption and gaseous concentrations (CO and NO x ) in the exhaust gas. The exhaust gas opacity while using Diesel/SME blends and Diesel fuel was also compared. The collected data show that oleic SME utilisation did not lead to a deterioration of engine performance or to an increase in fuel consumption. Furthermore, significant increases of NO x and CO concentrations in the exhaust gas derived from SME utilisation were not detected. The smoke opacity was slightly reduced when SME was used in the proportion of 30%. The experimental testing seems to indicate that oleic SME is a suitable replacement for Diesel fuel and can be used safely in compression ignition engines in proportions as high as 30%. (Author)

    Full Text Available The plant communities of the Blydeberg Conservancy were investigated as part of a research project on the foraging ecology of vervet monkeys Cercopithecus aethiops pygerythrus (senso lato in mixed lowveld bushveld and sour lowveld bushveld areas. To date there are no formal management plans for vervet monkeys. This is attributed to the limited knowledge of vervets and their utilisation of and impacts on ecosystems. From a TWINSPAN classification refined by Braun-Blanquet procedures, ten plant communities that can be placed into four major groups were identified. A classification and description of these communities, including a vegetation map are presented. Diagnostic species as well as prominent and less conspicuous species of tree, shrub, herb and grass strata are outlined. Of the ten available plant communities, the vervets utilised only six during the study period. There was an abundant supply of various food sources throughout the year, with movement patterns mostly coinciding with the fruiting times of several tree and other plant species.

  12. Progress towards Sustainable Utilisation and Management of Food Wastes in the Global Economy

    2016-01-01

    Full Text Available In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.

    Full Text Available Egg whites (EW are a good source of protein; however, they are typically heated prior to consumption. Therefore, we investigated the effects of different heating conditions on the protein utilisation rate of EW. Male Sprague-Dawley rats (n=36, 198±1 g were divided into six groups and fed American Institute of Nutrition-76 chow containing unheated EW, soft-boiled EW, boiled EW, milk whey protein, soybean protein, or no protein over a 10-day period using pair-feeding. Urine and faeces were sampled daily beginning on day 5 to measure nitrogen content and the net protein utilisation (NPU rate. The soybean protein group had a significantly lower level of food intake and was thus excluded from subsequent analyses. The NPU value was similar among the unheated, soft-boiled, and boiled EW groups (97.5±0.4, 96.5±0.1, and 96.5±0.7, resp.. The EW group values were significantly higher than the whey group values (90.5±1.0. These results show that EW serve as a good source of protein, irrespective of heating.

    2016-12-01

    The potential environmental impact of wasted food minimisation versus its utilisation in a circular bioeconomy is investigated based on a case study of Ireland. The amount of wasted food and food residue (WFFR) produced in 2010 was used for business-as-usual, (a) and four management options were assessed, (b) minimisation, (c) composting, (d) anaerobic digestion and (e) incineration. The environmental impacts Global Warming Potential (GWP), Acidification Potential (AP) and Eutrophication Potential (EP) were considered. A carbon return on investment (CRoI) was calculated for the three processing technologies (c-e). The results showed that a minimisation strategy for wasted food would result in the greatest reduction of all three impacts, -4.5 Mt CO 2 -e (GWP), -11.4 kt PO 4 3 -e (EP) and -43.9 kt SO 2 -e (AP) compared to business as usual. For WFFR utilisation in the circular bioeconomy, anaerobic digestion resulted in the lowest environmental impact and best CRoI of -0.84 kg CO 2 -e per Euro. From an economic perspective, for minimisation to be beneficial, 0.15 kg of wasted food would need to be reduced per Euro spent. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Foot problems are highly prevalent in the community; however no large population-based studies have examined the characteristics of those who do and do not access podiatry services in Australia. The aim of this study was to explore patterns of podiatry utilisation in a population-based sample of people aged 18 years and over living in the northwest region of Adelaide, South Australia. The North West Adelaide Health Study is a representative longitudinal cohort study of 4,060 people randomly selected and recruited by telephone interview. The interview included questions regarding healthcare service utilisation in the past year. Data were also collected on education, income and major medical conditions. Overall, 9.5% of the total sample and 17.7% of those who reported foot pain had attended a podiatrist in the past year. Participants who had accessed podiatry treatment were more likely to be female, be aged over 45 years, be obese, and have major chronic medical conditions (osteoporosis, osteoarthritis, diabetes, cardiovascular disease and high blood pressure). Those who reported foot pain but had not accessed a podiatrist were more likely to be male and be aged 20 to 34 years. Only a small proportion of people who report foot pain have accessed podiatry services in the past year. There is a need to further promote podiatry services to the general community, particularly to men and younger people.

    Full Text Available Abstract Background Foot problems are highly prevalent in the community; however no large population-based studies have examined the characteristics of those who do and do not access podiatry services in Australia. The aim of this study was to explore patterns of podiatry utilisation in a population-based sample of people aged 18 years and over living in the northwest region of Adelaide, South Australia. Methods The North West Adelaide Health Study is a representative longitudinal cohort study of 4,060 people randomly selected and recruited by telephone interview. The interview included questions regarding healthcare service utilisation in the past year. Data were also collected on education, income and major medical conditions. Results Overall, 9.5% of the total sample and 17.7% of those who reported foot pain had attended a podiatrist in the past year. Participants who had accessed podiatry treatment were more likely to be female, be aged over 45 years, be obese, and have major chronic medical conditions (osteoporosis, osteoarthritis, diabetes, cardiovascular disease and high blood pressure. Those who reported foot pain but had not accessed a podiatrist were more likely to be male and be aged 20 to 34 years. Conclusion Only a small proportion of people who report foot pain have accessed podiatry services in the past year. There is a need to further promote podiatry services to the general community, particularly to men and younger people.

    Women's autonomy is widely considered to be a key to improving maternal health in developing countries, whereas there is no consistent empirical evidence to support this claim. This paper examines whether or not and how women's autonomy within the household affects the use of reproductive health care, using a household survey data from Tajikistan. Estimation is performed by the bivariate probit model whereby woman's use of health services and the level of women's autonomy are recursively and simultaneously determined. The data is from a sample of women aged 15-49 from the Tajikistan Living Standard Measurement Survey 2007. Women's autonomy as measured by women's decision-making on household financial matters increase the likelihood that a woman receives antenatal and delivery care, whilst it has a negative effect on the probability of attending to four or more antenatal consultations. The hypothesis that women's autonomy and reproductive health care utilisation are independently determined is rejected for most of the estimation specifications, indicating the importance of taking into account the endogenous nature of women's autonomy when assessing its effect on health care use. The empirical results reconfirm the assertion that women's status within the household is closely linked to reproductive health care utilisation in developing countries. Policymakers therefore need not only to implement not only direct health interventions but also to focus on broader social policies which address women's empowerment.

    This study is against the backdrop that despite the forty-nine percent decline in Maternal Mortality Rate in Ghana, the situation still remains high averaging 319 per 100,000 live births between 2011 and 2015. To examine the relationship between National Health Insurance and maternal healthcare utilisation across three main wealth quintiles (Poor, Middle and Rich). The study employed data from the 2014 Ghana Demographic and Health Survey. Both descriptive analysis and binary logistic regression were conducted. Descriptively, rich women had high antenatal attendance and health facility deliveries represented by 96.5% and 95.6% respectively. However, the binary logistic regression results revealed that poor women owning NHIS are 7% (CI = 1.76-2.87) more likely to make at least four antenatal care visits compared to women in the middle wealth quintile (5%, CI = 2.12-4.76) and rich women (2%, CI = 1.14-4.14). Similarly, poor women who owned the NHIS are 14% (CI = 1.42-2.13) likely to deliver in health facility than women in the middle and rich wealth quintile. The study has vindicated the claim that NHIS Scheme is pro-poor in Ghana. The Ministry of Health should target women in the rural area to be enrolled on the NHIS to improve maternal healthcare utilisation since poverty is principally a rural phenomenon in Ghana.

    In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.

    The role of the nursing manager has evolved from clinician and bed manager to one with greater accountability for evidence based practice, benchmarking and more recently, budget liability. Casemix data are widely believed to be a means of providing essential information for effective decision making and financial management but have not been widely utilised by nursing managers (Diers & Bozzo, 1999). This paper will report the results of a survey of nursing managers in seven hospitals within a metropolitan area health service. The hospitals include tertiary referral hospitals, specialist public hospitals and an affiliated public hospital for aged care and rehabilitation services. The survey sought to establish what casemix and related data were provided to nurse managers, who provided these data and how supplied data were utilised by the nurse managers. Results demonstrated that the majority of nursing managers surveyed received minimal (if any) casemix and/or demographic data on a routine basis. Some were provided with data in response to specific requests. The information that was provided varied both within and across hospitals, and no consistent methods of data distribution were available. Few nursing managers believed that the information provided aided their decision-making processes partly due to the minimalist nature of provided data while some nursing managers demonstrated a lack of understanding of the potential benefit of casemix data as a resource to support management decision making.

    Full Text Available Abstract Background There is evidence suggesting that the use of health services is lower among immigrants after adjusting for age and sex. This study takes a step forward to compare primary care (PC utilisation patterns between immigrants and the native population with regard to their morbidity burden. Methods This retrospective, observational study looked at 69,067 individuals representing the entire population assigned to three urban PC centres in the city of Zaragoza (Aragon, Spain. Poisson models were applied to determine the number of annual PC consultations per individual based on immigration status. All models were first adjusted for age and sex and then for age, sex and case mix (ACG System®. Results The age and sex adjusted mean number of total annual consultations was lower among the immigrant population (children: IRR = 0.79, p Conclusions Although immigrants make lower use of PC services than the native population after adjusting the consultation rate for age and sex, these differences decrease significantly when considering their morbidity burden. These results reinforce the 'healthy migration effect' and discount the existence of differences in PC utilisation patterns between the immigrant and native populations in Spain.

    Prescription audit is a powerful tool for rational prescription. To evaluate pharmaco-epidemiology of drugs utilised for cataract surgery, a retrospective study was conducted in the department of pharmacology, RG Kar Medical College, Kolkata. Data from bed head tickets of one year, available in medical record section, were collected in case report forms and analysed. Utilisation pattern of drugs like dosage form, dose, route and frequency of administration and duration of therapy were audited. Drug prescription versus therapeutic indication was also evaluated. Price of the prescribed drugs was evaluated for rationality towards cost-effective prescription. For 848 cases of cataract surgery, drugs were prescribed pre-, per- and post-operatively. Different fluoroquinolone antibiotics, anti-inflammatory and mydriatic-cycloplegic agents were prescribed. High or low cost drugs were prescribed both in generic (52%) and brand (48%) names. Few Latin abbreviations were used in directions. Different parameters and study results were discussed from various aspects to explore their social impacts. Though prescription pattern was almost rational, some parts need improvement. Healthcare provider should be aware of cost-effectiveness of the prescribed drugs for the benefit of patients to provide a rational prescription.

    Full Text Available Techno-economic models for optimised utilisation of jatropha oil under an out-grower farming scheme were developed based on different considerations for oil and by-product utilisation. Model 1: Out-grower scheme where oil is exported and press cake utilised for compost. Model 2: Out-grower scheme with six scenarios considered for the utilisation of oil and by-products. Linear programming models were developed based on outcomes of the models to optimise the use of the oil through profit maximisation. The findings revealed that Model 1 was financially viable from the processors’ perspective but not for the farmer at seed price of $0.07/kg. All scenarios considered under Model 2 were financially viable from the processors perspective but not for the farmer at seed price of $0.07/kg; however, at seed price of $0.085/kg, financial viability was achieved for both parties. Optimising the utilisation of the oil resulted in an annual maximum profit of $123,300.

    To examine the impact of frailty on medical and social care utilisation among the Irish community-dwelling older population to inform strategies of integrated care for older people with complex needs. Participants aged ≥65 years from the Irish Longitudinal Study on Ageing (TILDA) representative of the Irish community-dwelling older population were analysed (n = 3507). The frailty index was used to examine patterns of utilisation across medical and social care services. Multivariate logistic and negative binomial regression models were employed to examine the impact of frailty on service utilisation outcomes after controlling for other factors. The prevalence of frailty and pre-frailty was 24% (95% CI: 23, 26%) and 45% (95% CI: 43, 47%) respectively. Frailty was a significant predictor of utilisation of most social care and medical care services after controlling for the main correlates of frailty and observed individual effects. Frailty predicts utilisation of many different types of healthcare services rendering it a useful risk stratification tool for targeting strategies of integrated care. The pattern of care is predominantly medical as few of the frail older population use social care prompting questions about sub-groups of the frail older population with unmet care needs.

  6. Utilisation of VOC in Diesel Engines. Ignition and combustion of VOC released in crude oil tankers

    The emission of VOC (Volatile Organic Compound) is a significant source of hydrocarbon pollution. In Norway, the offshore oil industry represents a major source. This emission represents both an energy loss and an environmental problem. Gas tankers have used boil-off gas from the cargo tanks as fuel for some time. However, for the current VOC project a new fuel injection concept is designed for tankers to take advantage of the energy present in the VOC evaporated from crude oil. The VOC is mixed with inert gas in these tankers, and thus the utilisation of this gas represents new challenges. The VOC project uses the concept of ''Condensate Diesel Process'' with pilot ignition. An experimental study of ignition and combustion of VOC Fuels reported here was initiated by the time it was decided to start a pilot project converting propulsion engines in shuttle tankers to use VOC Fuel. It is an experimental study carried out at the Marine Technology Centre (MTS). The objective was to study ignition and combustion of the chosen process in comparison with an ordinary diesel process. The experimental results have been discussed and compared with theoretical considerations of injection, ignition and combustion. For experiments on combustion, a rapid compression machine ''DyFo'' was redesigned to use VOC Fuel. The DyFo test rig was initially designed to study ignition and early combustion of spark ignited homogeneous gas/air charges. To study the ignition and early combustion of VOC Fuel injected at high pressure and ignited by pilot diesel fuel, a redesign was necessary. An important feature of the DyFo, is the visualisation of the combustion. The advantage of the DyFo test rig over an engine, is its simplicity and controllability. In an engine the visualisation would suffer from combustion deposits disturbing the view through the quartz glasses, making the images more difficult to interpret. The simplicity is on the other side a drawback. Correct thermal conditions inside

    Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context. Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications. Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2-17.9) and depression/anxiety (OR 5.8, 95% CI: 2.2-15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3-12.7; OR 3.4, 95% CI: 1.2-10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1-11.9; OR 3.3, 95% CI: 1.0-10.4) or post migration stressors (OR 17.3, 95% CI: 4.9-60.8; OR 3.9, 95% CI: 1.2-12.3) were independent predictors of self reported PTSD or depression/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (chi2 = 19.74, df = 1, P refugees, while no significant difference was found between these groups for use of dentists, medication, hospitalisation or mental health services.

    Aim: To assess the utilisation of an interventional radiology day unit (RDU), the rates of on-time discharges, the financial performance of the unit, and finally, the patient satisfaction rates. Materials and methods: Data regarding the unit utilisation, discharge times, and complications were retrospectively collected for the first 2 years of operation of the unit (1 April 2013 to 1 January 2015). In addition, monitoring the activity going through the RDU and applying a contribution margin to the freed-up beds measured the financial performance. The data were provided by the finance department of the hospital. Satisfaction survey questionnaires were sent randomly by post to 100 patients who had been previously admitted to the RDU. Results: During the study period, 3019 patients were admitted to the RDU, comprising 1426 during the first year and 1513 during the second. On average, 5.6 patients were discharged from the RDU on every working day during the first year and 7.1 patients during the second (21% increase in the discharge rate). Given the 8-hour working time configuration of the unit, a realistic 80% utilisation rate of the RDU's seven beds could free a total of 1400 inpatient bed days over a full year. The cost of delivering these episodes of care was reduced by approximately 50%. From the financial data, it was estimated that the RDU managed to achieve a total of £393,000 in savings for the Trust for the financial year 2013–2014. The return rate of the patient satisfaction survey was 40%. All patients were satisfied with their overall RDU experience. Conclusion: The RDU has brought significant benefits for patients and the Trust without compromises in safety or quality. - Highlights: • Radiology Day units can improve workflow through improved efficiency. • RDUs can decrease the treatment-related costs mainly by reducing the need for unnecessary overnight hospitalisation. • They appear to be welcome by the patients with excellent feedback so far.

    Globally, insufficient information exists on the costs of nursing agencies, which are temporary employment service providers that supply nurses to health establishments and/or private individuals. The aim of the study was to determine the utilisation and direct costs of nursing agencies in the South African public health sector. A survey of all nine provincial health departments was conducted to determine utilisation and management of nursing agencies. The costs of nursing agencies were assumed to be equivalent to expenditure. Provincial health expenditure was obtained for five financial years (2005/6-2009/10) from the national Basic Accounting System database, and analysed using Microsoft Excel. Each of the 166,466 expenditure line items was coded. The total personnel and nursing agency expenditure was calculated for each financial year and for each province. Nursing agency expenditure as a percentage of the total personnel expenditure was then calculated. The nursing agency expenditure for South Africa is the total of all provincial expenditure. The 2009/10 annual government salary scales for different categories of nurses were used to calculate the number of permanent nurses who could have been employed in lieu of agency expenditure. All expenditure is expressed in South African rands (R; US$1 ∼ R7, 2010 prices). Only five provinces reported utilisation of nursing agencies, but all provinces showed agency expenditure. In the 2009/10 financial year, R1.49 billion (US$212.64 million) was spent on nursing agencies in the public health sector. In the same year, agency expenditure ranged from a low of R36.45 million (US$5.20 million) in Mpumalanga Province (mixed urban-rural) to a high of R356.43 million (US$50.92 million) in the Eastern Cape Province (mixed urban-rural). Agency expenditure as a percentage of personnel expenditure ranged from 0.96% in KwaZulu-Natal Province (mixed urban-rural) to 11.96% in the Northern Cape Province (rural). In that financial year

    Imaging using more than one biological process using PET could be of great utility, but despite previously proposed approaches to dual-tracer imaging, it is seldom performed. The alternative of performing multiple scans is often infeasible for clinical practice or even in research studies. Dual-tracer PET scanning allows for multiple PET radiotracers to be imaged within the same imaging session. In this paper we describe our approach to utilise the basis pursuit method to aid in the design of dual-tracer PET imaging experiments, and later in separation of the signals. The advantage of this approach is that it does not require a compartment model architecture to be specified or even that both signals are distinguishable in all cases. This means the method for separating dual-tracer signals can be used for many feasible and useful combinations of biology or radiotracer, once an appropriate scanning protocol has been decided upon. Following a demonstration in separating the signals from two consecutively injected radionuclides in a controlled experiment, phantom and list-mode mouse experiments demonstrated the ability to test the feasibility of dual-tracer imaging protocols for multiple injection delays. Increases in variances predicted for kinetic macro-parameters V D and K I in brain and tumoral tissue were obtained when separating the synthetically combined data. These experiments confirmed previous work using other approaches that injections delays of 10-20 min ensured increases in variance were kept minimal for the test tracers used. On this basis, an actual dual-tracer experiment using a 20 min delay was performed using these radio tracers, with the kinetic parameters (V D and K I) extracted for each tracer in agreement with the literature. This study supports previous work that dual-tracer PET imaging can be accomplished provided certain constraints are adhered to. The utilisation of basis pursuit techniques, with its removed need to specify a model

    The study of new radiolabelled ligands will impose further demands for rapid dynamic data acquisition and accurate tracer quantification. Current and future developments in PET technology range from the use of new detector materials to different detector geometries and data acquisition modes. The search for alternatives to BGO scintillation materials for PET has led to the development of PET instruments utilising new crystals such as LSO and GSO. The use of these new detectors and the increased sensitivity achieved with 3D data acquisitions represent the most significant current developments in the field. With the increasing demands imposed on the clinical utilisation of PET, issues such as study cost and patient throughput will emerge as significant future factors. As a consequence, low-cost units are being offered by the manufacturers through the utilisation of gamma camera-based SPET systems for PET coincidence imaging. Unfortunately, clinical studies in lymphoma and other cancers have already demonstrated the limitations of this technology, with 20% of lesions <15 mm in size escaping detection. On the other hand, the recent development of combined PET/CT devices attempts to address the lack of anatomical information inherent with PET images, taking advantage of further improvement in patient throughput and hence cost-effectiveness. Preliminary studies using this multimodality imaging approach have already demonstrated the potential of the technique. Although the potential exists, certain technical issues with PET/CT require refinement of the methodology. Such issues include organ movement (such as respiratory motion), which strongly influences the image fusion of a rapidly acquired CT scan with the slower acquisition of a PET dataset, and the derivation of CT-based attenuation coefficients in the presence of contrast agents or metallic implants. The application of the technology for radiotherapy planning also poses a number of associated challenges. Finally

    Little research into non-western women's prenatal care utilisation in industrialised western countries has taken generational differences into account. In this study we examined non-western women's prenatal care utilisation and its explanatory factors according to generational status. Data from 3300 women participating in a prospective cohort of primary midwifery care clients (i.e. women with no complications or no increased risk for complications during pregnancy, childbirth and the puerperium who receive maternity care by autonomous midwives) in the Netherlands (the DELIVER study) was used. Gestational age at entry and the total number of prenatal visits were aggregated into an index. The extent to which potential factors explained non-western women's prenatal care utilisation was assessed by means of blockwise logistic regression analyses and percentage changes in odds ratios. The unadjusted odds of first and second-generation non-western women making inadequate use of prenatal care were 3.26 and 1.96 times greater than for native Dutch women. For the first generation, sociocultural factors explained 43% of inadequate prenatal care utilisation, socioeconomic factors explained 33% and demographic and pregnancy factors explained 29%. For the second generation, sociocultural factors explained 66% of inadequate prenatal care utilisation. Irrespective of generation, strategies to improve utilisation should focus on those with the following sociocultural characteristics (not speaking Dutch at home, no partner or a first-generation non-Dutch partner). For the first generation, strategies should also focus on those with the following demographic, pregnancy and socioeconomic characteristics (aged ≤ 19 or ≥ 36, unplanned pregnancies, poor obstetric histories (extra-uterine pregnancy, molar pregnancy or abortion), a low educational level, below average net household income and no supplementary insurance.

    Full text: Cerebral perfusion imaging is a common technique to assess cerebral perfusion and metabolism. It can complement anatomical imaging in assessing a number of neurological conditions. At times it can better define the clinical manifestations of a disease process than anatomical imaging alone. We present a clinical case whereby cerebral SPECT imaging helped define the physiological reason for intermittent aphasia in a patient with tumor active multiple sclerotic white matter plaques. Cerebral SPECT studies were performed during a period of aphasia and when the patient had recovered. We utilised subtraction analyses and image fusion techniques to better define the changes seen on SPECT. We discuss the neuroanatomical relationship of aphasia and the automatic fusion technique that allows accurate co-registration of the MRI and SPECT data.

    With the rapid development of electronic business, Web services have attracted much attention in recent years. Enterprises can combine individual Web services to provide new value-added services. An emerging challenge is the timely discovery of close matches to service requests among large service pools. In this study, we first define a new semantic similarity measure combining functional similarity and process similarity. We then present a service discovery mechanism that utilises the new semantic similarity measure for service matching. All the published Web services are pre-grouped into functional clusters prior to the matching process. For a user's service request, the discovery mechanism first identifies matching services clusters and then identifies the best matching Web services within these matching clusters. Experimental results show that the proposed semantic discovery mechanism performs better than a conventional lexical similarity-based mechanism.

    In a sewage plant with radioactively contaminated sewage an accumulation of radionuclides was found in the sewage sludge. The specific activities are in inverse proportion to the water content of the sewage sludge, the dehydrated sewage sludge having the highest specific activities. The retained radionuclides seem to be firmly accumulated in the sludge. Nevertheless, they are in a form which can be utilised by plants. This was demonstrated in experiments with Trifolium Repens and Secale Cereale where the rate of absorption was 15-33% (in Ci/kg dry weight per plant: nCi/kg dry weight soil x 100). Thus there are problems associated with using radioactively contaminated sewage sludge as a fertiliser. In further experiments to extract radioactive nuclides from ashed sewage sludge it was shown that acidifying the aqueous phase results in an increase in the level of radioactivity in the eluated fractions.

  18. Practical operation strategies for pumped hydroelectric energy storage (PHES) utilising electricity price arbitrage

    DEFF Research Database (Denmark)

    Connolly, David; Lund, Henrik; Finn, P.

    2011-01-01

    In this paper, three practical operation strategies (24Optimal, 24Prognostic, and 24Hsitrocial) are compared to the optimum profit feasible for a PHES facility with a 360 MW pump, 300 MW turbine, and a 2 GWh storage utilising price arbitrage on 13 electricity spot markets. The results indicate...... that almost all (not, vert, similar97%) of the profits can be obtained by a PHES facility when it is optimised using the 24Optimal strategy developed, which optimises the energy storage based on the day-ahead electricity prices. However, to maximise profits with the 24Optimal strategy, the day......-ahead electricity prices must be the actual prices which the PHES facility is charged or the PHES operator must have very accurate price predictions. Otherwise, the predicted profit could be significantly reduced and even become a loss. Finally, using the 24Optimal strategy, the PHES profit can surpass the annual...

  19. Utilisation of thin-seam drum shearer loaders at Bergbau AG Niederrhein

    Conventional shearer loaders which travel on the AFC can only be used in seams more than 1.6 m thick in the conditions of the Ruhr coalfield. Low design shearers have been developed for seams below 1.6 m, and can work in conditions down to 1.0 m seam thickness. At Bergbau AG Niederrhein these machines have been adapted to prevailing conditions and requirements. The demand for a high drive rating led to a thin-seam shearer thickness from 1.3 m upwards. The need for minimum feasible machine height with adequate drive rating has been obtained with another machine. Currently under development is a machine which should lower the utilisation limit of thin-seam shearers. With planning and the use of suitable types of supports, it is possible to work faces by shearer in seams of 1.0 m upwards, even under difficult extraction conditions.

    A pot experiment was conducted with groundnut applying labelled calcium as its sulphate and carbonate at two levels namely 75 and 150 kg Ca per ha with varying levels of P, K and Mg. Plant samples were taken at different stages of crop growth and analysed for the content of radioactive calcium. Calcium sulphate treatment has resulted in larger uptake of calcium compared to calcium carbonate. An application of 150 kg Ca per ha has caused significantly higher uptake by groundnut plant than 75 kg Ca per ha. The percentage of utilisation of added calcium ranged from 2.2 to 5.4 Recovery of calcium by plants was more in calcium sulphate treatment rather than in calcium carbonate. The plants showed a preference for absorbing applied calcium rather than native calcium.

    The safety culture of selected practices and facilities in Ghana utilising radiation sources or radiation emitting devices has been assessed using a performance indicator, which provided status information on management and operating staff commitment to safety. The questionnaire was based on the following broad areas: general safety considerations, safety policy at the facility level, safety practices at the facility level, definition of responsibility, staff training, safety of the physical structure of the facility and the emergency plans. The analysis showed that the percentage levels of commitment to safety for the respective practices are as follows: conventional radiography, 23.3-90.0%; research reactor, 73.3 %; gamma irradiation facility, 53.3%; radiotherapy, 76.7%; X-ray scanner, 80.0%; gamma scanner, 76.7%; industrial radiography 86.7% and nuclear density practice, 78%. None of the practices or facilities was able to satisfy all the requirements that will ensure a 100% level of safety culture. (authors)

    The general purpose neutron-photon-electron Monte Carlo N-Particle code, MCNP sup T sup M , has been used to simulate the neutronic characteristics of the on-site laboratory passive neutron coincidence counter to be installed, under Euratom Safeguards Directorate supervision, at the Sellafield reprocessing plant in Cumbria, UK. This detector is part of a series of nondestructive assay instruments to be installed for the accurate determination of the plutonium content of nuclear materials. The present work focuses on one aspect of this task, namely, the accurate calculation of the coincidence gate utilisation factor. This parameter is an important term in the interpretative model used to analyse the passive neutron coincidence count data acquired using pulse train deconvolution electronics based on the shift register technique. It accounts for the limited proportion of neutrons detected within the time interval for which the electronics gate is open. The Monte Carlo code MCF, presented in this work, represents...

    The Tattapani Geothermal field produces + 1800 1pm thermal water of 100{degrees}C from five production wells. The hot water production can sustain electricity production of 300 kWe by using a binary cycle power plant. The heat energy of effluent water from power plant can be utilized for direct heat utilization on horticulture, aquaculture, cold storage, silviculture etc; to augment the economics of the power plant be spot can be developed as a centre for tourist attraction by constructing botanical park, greenhouse, geyser show and crocodile farm. The direct heat utilization shemes can be planned in cascading order to achieve maximum utility of thermal water. Additional deep drilling is essential for optimum commercial utilization of the Geothermal energy. The direct heat utilisation shemes along with binary cycle power plant may help in development of the geothermal energy and boosting the economy of this region.

    The presented study aimed at investigating the residual feed intake (RFI) of Sahiwal calves, nutrient utilisation as affected by RFI and its relationship with methane (CH4) emissions and some blood metabolites. Eighteen male Sahiwal calves (10-18 months of age; mean body weight 133 kg) were fed ad libitum with a total mixed ration. After calculating RFI for individual calves (-0.40 to +0.34 kg DM/d), they were divided into three groups with low, medium and high RFI, respectively. Dry matter intake (DMI) was higher (p feed conversion ratio were similar among the groups. With exception of glucose, concentrations of all measured blood metabolites were higher in Group High RFI (p feed efficiency and less CH4 production were observed in Group Low RFI, it was concluded that RFI can be used as a measure of feed efficiency, which has a potential to select Sahiwal calves for lowered CH4 emissions.

    Full Text Available Abstract Background Concern about the use of endangered and threatened species in traditional medicine escalated as populations of many species plummeted because of poaching for the medicinal trade. Nigeria is known for a long and valued tradition of using wild animals and plants for medicinal purposes. Despite this, studies on medicinal animals are still scarce when compared to those focusing on medicinal plants. Utilisation of wild animals in traditional Yorubic medical practices was indiscriminate as it involved threatened species. By touting the medicinal properties of these species, traditional medicine fuel continuing demand, thereby subjecting such species to further threats. This paper examined the use and commercialisation of pangolins for traditional medicinal purposes amongst the Ijebus, South-western Nigeria, and the implications of this utilisation for the conservation of this species. Methods Traditional Yorubic medical practitioners (tymps (16 and dealers in traditional medicinal ingredients (56 in public markets in Ijebu province, Nigeria, were interviewed using open-ended questionnaires. The dynamic stock movement of pangolins in the stalls of dealers was also monitored to determine quantity of pangolins sold into the traditional Yorubic medicinal practices. Specific conditions treated and the parts required were also documented. Results A total of 178 whole pangolin carcasses were sold into traditional medical practices. Above 55% of respondents had just primary education, over 90% of respondents were not aware of either the conservation status of this species or the existence of any legal machinery regulating its trade and utilisation, while 14% admitted to giving contracts to hunters for deliberate search for this animal when needed. More than 98% of respondents have no other means of livelihood. The trade was female dominated while the healing practice had more males. Pangolins were used in various preparations to treat a

    This article is concerned with the methodological issues of assessing the effects of casemix funding on hospital utilisation. Time-series analysis and intervention analysis are proposed to ascertain the effects. It was found there had been a decline in average length of stay and number of bed-days, an increase in weighted separations for teaching and non-teaching hospitals, and no apparent increase of costliness in terms of a comprehensive casemix index. No evidence of decline in quality of care can be established in terms of readmission rates. The long-term effects of casemix funding, and specific issues in terms of the funding model used, patients and cost shifting between hospital services and community health services, remain to be studied.

    Full Text Available Abstract Background As one of the most populous metropolitan areas in the Pearl River Delta of South China, Shenzhen attracts millions of migrant workers annually. The objectives of this study were to compare health needs, self-reported health and healthcare utilisation of insured and uninsured migrant workers in Shenzhen, China, where a new health insurance scheme targeting at migrant workers was initiated. Methods A cross-sectional survey using multi-staged sampling was conducted to collect data from migrant factory workers. Statistical tests included logistic regression analysis were used. Results Among 4634 subjects (96.54% who responded to the survey, 55.11% were uninsured. Disease patterns were similar irrespective of insurance status. The uninsured were more likely to be female, single, younger and less educated unskilled labourers with a lower monthly income compared with the insured. Out of 1136 who reported illness in the previous two weeks, 62.15% did not visit a doctor. Of the 296 who were referred for inpatient care, 48.65% did not attend because of inability to pay. Amongst those who reported sickness, 548 were insured and 588 were uninsured. Those that were insured, and had easier access to care were more likely to make doctor visits than those who were uninsured. Conclusion Health care utilisation patterns differ between insured and uninsured workers and insurance status appears to be a significant factor. The health insurance system is inequitably distributed amongst migrant workers. Younger less educated women who are paid less are more likely to be uninsured and therefore to pay out of pocket for their care. For greater equity this group need to be included in the insurance schemes as they develop.

    Full Text Available Abstract Background In this era of evidence-based medicine, doctors are increasingly using information technology to acquire medical knowledge. This study evaluates how residents and interns utilise and perceive the personal digital assistant (PDA and the online resource UpToDate. Methods This is a questionnaire survey of all residents and interns in a tertiary teaching hospital. Results Out of 168 doctors, 134 (79.8% responded to the questionnaire. Only 54 doctors (40.3% owned a PDA. Although these owners perceived that the PDA was most useful for providing drug information, followed by medical references, scheduling and medical calculators, the majority of them did not actually have medical software applications downloaded on their PDAs. The greatest concerns highlighted for the PDA were the fear of loss and breakage, and the preference for working with desktop computers and paper. Meanwhile, only 76 doctors (56.7% used UpToDate, even though the hospital had an institutional subscription for it. Although 93.4% of these users would recommend UpToDate to a colleague, only 57.9% stated that the use of UpToDate had led to a change in their management of patients. Conclusion Although UpToDate and various PDA software applications were deemed useful by some of the residents and interns in our study, both digital tools were under-utilised. More should be done to facilitate the use of medical software applications on PDAs, to promote awareness of tools for evidence-based medicine such as UpToDate, and to facilitate the application of evidence-based medicine in daily clinical practice.

  15. Three-Axis Attitude Control of Solar Sails Utilising Reflectivity Control Devices

    Science.gov (United States)

    Theodorou, Theodoros

    Solar sails are spacecraft that utilise the Solar Radiation Pressure, the force generated by impinging photons, to propel themselves. Conventional actuators are not suitable for controlling the attitude of solar sails therefore specific attitude control methods have been devised to tackle this. One of these methods is to change the centre of pressure with respect to the center of mass thus creating a torque. Reflectivity Control Devices (RCDs) have been proposed and successfully used to change the centre of pressure. Current methods that utilise RCDs have control authority over two axis only with no ability to control the torque about the normal of the sail surface. This thesis extends the state of the art and demonstrates 3-axis control by generating arbitrary torque vectors within a convex polyhedron. Two different RCD materials are considered, transmission and diffusion technologies both compatible with the proposed concept. A number of metrics have been developed which facilitate the comparison of different sail configurations. One of these metics is the sun map which is a graphic representation of the sun angles for which control authority is maintained. An iterative design process is presented which makes use of the metrics developed and aids in the design of a sail which meets the mission requirements and constraints. Moreover, the effects of different parameters on the performance of the proposed control concept are discussed. For example it is shown that by alternating the angle between the edge and middle RCDs the control authority increases. The concept's scalability has been investigated and a hybrid control scheme has been devised which makes use of both RCDs and reaction wheels. The RCDs are complemented by the reaction wheels to achieve higher slew rates while in turn the RCDs desaturate the reaction wheels. Finally, a number of simulations are conducted to verify the validity of the proposed concept.

    2011-04-01

    Full Text Available Abstract Background The Nepal Demographic Health Survey (NDHS in 2006 showed that more than half (56% of the women with sexually transmitted infections (STIs, including HIV, in Nepal sought sexual health services. There is no such data for female sex workers (FSWs and the limited studies on this group suggest they do not even use routine health services. This study explores FSWs use of sexual health services and the factors associated with their use and non-use of services. Methods This study aimed to explore the factors associated with utilisation of sexual health services by FSWs in the Kathmandu Valley of Nepal, and it used a mixed-method approach consisting of an interviewer administered questionnaire-based survey and in-depth interviews. Results The questionnaire survey, completed with 425 FSWs, showed that 90% FSWs self-reported sickness, and (30.8% reported symptoms of STIs. A quarter (25% of those reporting STIs had never visited any health facilities especially for sexual health services preferring to use non-governmental clinics (72%, private clinics (50%, hospital (27% and health centres (13%. Multiple regression analysis showed that separated, married and street- based FSWs were more likely to seek health services from the clinics or hospitals. In- depth interviews with 15 FSWs revealed that FSWs perceived that personal, structural and socio-cultural barriers, such as inappropriate clinic opening hours, discrimination, the judgemental attitude of the service providers, lack of confidentiality, fear of public exposure, and higher fees for the services as barriers to their access and utilisation of sexual health services. Conclusion FSWs have limited access to information and to health services, and operate under personal, structural and socio-cultural constraints. The 'education' to change individual behaviour, health worker and community perceptions, as well as the training of the health workers, is necessary.

    The purpose of this paper is to discuss the alternative environmental management options for the utilisation of municipal solid waste (MSW) incineration fly ash (FA), which is generated at Iru Power Plant where MSW is incinerated in Estonia. To determine sustainable and economically feasible environmental management options for MSW incineration FA in Estonia, CO 2 sequestration with a further carbonation process was examined. A partial Cost & Benefit Analysis has been conducted to compare the carbonation process to the current situation. Two carbonation options were developed. Option 1 is to use carbonated FA in any other processes based on the waste-to-product principle. Option 2 is to send carbonated FA to the non-hazardous landfill in Tallinn, Estonia. Important parameters, such as Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost Ratio (BCR) and Break Even Point (BEP), have been calculated for carbonation options and the current case. In addition, a sensitivity analysis has been conducted to examine its robustness. The results showed that the best option is carbonation Option 1 with NPV of 9,209,662 EUR, IRR of 43%, BCR of 2.63 and BEP between 2018 and 2019. Both Options 1 and 2 constitute more sustainable and environmentally friendly management options compared to the current situation. It can be concluded that this preliminary feasibility study showed that running a carbonation plant may be profitable and sustainable for Estonia. Currently, there is no treatment technology for MSW incineration FA in Estonia and FA is sent to a neighbouring country for further utilisation. This is the first study to demonstrate FA management options with economic and environmental benefits.

    Full Text Available Abstract Background Seeking and utilisation of HIV prevention, treatment, care, and support services for people living with HIV is often hampered by HIV-related stigma. The study aimed to explore the perceptions and experiences regarding treatment, care, and support amongst people living with HIV in Viet Nam, where the HIV epidemic is concentrated among injecting drug users, sex workers, and men who have sex with men. Methods In-depth interviews and focus group discussions were conducted during September 2007 in 6 districts in Hai Phong with a very high HIV prevalence among injecting drug users. The information obtained was analysed and merged within topic areas. Illustrative quotes were selected. Results Stigma and discrimination against people living with HIV in the community and healthcare settings was commonly reported, and substantially hampered the seeking and the utilisation of HIV-related services. The informants related the high level of stigma to the way the national HIV preventive campaigns played on fear, by employing a “scare tactic” mainly focusing on drug users and sex workers, who were defined as “social evils” in the anti-drug and anti-prostitution policy. There was a strong exclusion effect caused by the stigma, with serious implications, such as loss of job opportunities and isolation. The support and care provided by family members was experienced as vital for the spirit and hope for the future among people living with HIV. Conclusions A comprehensive care and support programme is needed. The very high levels of stigma experienced seem largely to have been created by an HIV preventive scare tactic closely linked to the “social evil“ approach in the national policy on drug and prostitution. In order to reduce the stigma and create more effective interventions, this tactic will have to be replaced with approaches that create better legal and policy environments for drug users and sex workers.

In addition, contraceptive use was significantly higher among those living in a nuclear family system (P <0.050. A univariate analysis indicated significant associations between contraceptive use and age, nationality, education level, type of family system, employment sector, parity, knowledge of birth control measures and source of birth control information (P <0.050 each. However, no significant associations were found via multivariate analysis. Conclusion: Healthcare practitioners can play a pivotal role in providing contraceptive advice which could lead to an improvement in contraceptive utilisation. Efforts are recommended to raise awareness regarding newer forms of contraceptives among mothers of reproductive age in the UAE.

    Full Text Available Background: Primary healthcare is established to ensure that people have access to health services through facilities located in their community. However, utilisation of health facilities in Nigeria remains low in many communities. Aim: To assess the utilisation of community-based health facility (CBHF amongst adults in Ibadan, Nigeria. Settings: A low-income community in Ibadan North West Local Government Area of Oyo State.Methods:A cross-sectional survey was conducted using a simple random sampling technique to select one adult per household in all 586 houses in the community. A semi-structured interviewer-administered questionnaire was used to collect information on respondents’ sociodemographic characteristics, knowledge and utilisation of the CBHF. Data analysis included descriptive statistics and association testing using the Chi-square test at p = 0.05. Results: The mean age of the respondents was 46.5 ± 16.0 years; 46.0% were men and 81.0% married; 26% had no formal education and 38.0% had secondary-level education and above; traders constituted 52.0% of the sample; and 85.2% were of low socioeconomic standing; 90%had patronised the CBHF. The main reasons for non-utilisation were preference for general hospitals (13.8% and self-medication (12.1%. Respondents who had secondary education and above, were in a higher socioeconomic class, who had good knowledge of the facility and were satisfied with care, utilised the CBHF three months significantly more than their counterparts prior to the study (p < 0.05. However, only satisfaction with care was found to be a significant predictor of utilisation of the CBHF. Conclusion: The utilisation of the CBHF amongst adults in the study setting is high, driven mostly by satisfaction with the care received previously. Self-medication, promoted by uncontrolled access to drugs through pharmacies and patent medicine stores, threatens this high utilisation.

    This note describes an automatic control device for the programming of about 20 different functions, chronologically and during a given time. Any voltage can be chosen at the output to perform the different functions. Three examples of utilisation taken in analytical chemistry are given to illustrate the possibilities offered by this device, but its domain of use is much more universal and independent of the type of functions [French] Description d'un dispositif de commande automatique destine a programmer une vingtaine de fonctions differentes dans l'ordre et pendant le temps desire. Aux bornes d'utilisation de ce dispositif, on peut choisir a volonte du 24 V continu, du 220 V alternatif ou un contact de court-circuit pour realiser les fonctions elles-memes. Afin d'illustrer concretement les possibilites de cet appareil, il est donne trois exemples d'utilisation empruntes a la chimie analytique pour laquelle il a ete prevu initialement. En realite, son domaine d'utilisation est beaucoup plus universel, car il est relativement independant de la nature des fonctions. (auteurs)

    Urban population in China is mainly covered by two medical insurance schemes: the Urban Employee Basic Medical Insurance (UEBMI) for urban employees in formal sector and the Urban Resident Basic Medical Insurance (URBMI) for the left urban residents, mainly the unemployed, the elderly and children. This paper studies the effects of UEBMI and URBMI on health services utilisation in Shaanxi Province, Western China. Cross-sectional data from the 4th National Health Services Survey - Shaanxi Province was studied. The propensity score matching and the coarsened exact matching methods have been used to estimate the average medical insurance effect on the insured. Compared to the uninsured, robust results suggest that UEBMI had significantly increased the outpatient health services utilisation in the last two weeks (pinsured was associated with higher health services utilisation, compared with the uninsured, none of the improvement was statistically significant (p>0.10). It was also found that compared with the uninsured, basic medical insurance enrollees were more likely to purchase inpatient treatments in lower levels of hospitals, consistent with the incentive of the benefit package design. Basic Medical insurance schemes have shown a positive but limited effect on increasing health services utilisation in Shaanxi Province. The benefit package design of higher reimbursement rates for lower level hospitals has induced the insured to use medical services in lower level hospitals for inpatient services.

    In Germany, utilisation of ambulatory healthcare services is high compared with other countries: While a study based on the process data of German statutory health insurances showed an average of 17.1 physician-patient-contacts per year, the comparable figure for Norway is about five. The usual models of healthcare utilisation, such as Rosenstock's Health Belief Model and Andersen's Behavioural Model, cannot explain these differences adequately. Organisational factors of the healthcare system, such as gatekeeping, do not explain the magnitude of the differences. Our hypothesis is that patients' subjective concepts about primary healthcare utilisation play a major role in explaining different healthcare utilisation behaviour in different countries. Hence, the aim of this study is to explore these subjective concepts comparatively, between Germany and Norway. With that aim in mind, we chose a comparative qualitative study design. In Norway and Germany, we are going to interview 20 patients each with qualitative episodic interviews. In addition, we are going to conduct participant observation in four German and four Norwegian primary care practices. The data will be analysed by thematic coding. Using selected categories, we are going to conduct comparative case and group analyses. The study adheres to the Declaration of Helsinki. All interviewees will sign informed consent forms and all patients will be observed during consultation. Strict rules for data security will apply. Developed theory and policy implications are going to be disseminated by a workshop, presentations for experts and laypersons and publications.

    As a social protection policy, Ghana's National Health Insurance Scheme (NHIS) aims to improve access to healthcare, especially for the vulnerable. Migrant female head porters ( kayayoo ), who are part of the informal economic workforce, are underscored as an ethnic minority and vulnerable group in Ghana. This study aimed to analyse the factors associated with enrolment in and renewal and utilisation of the NHIS among migrant female head porters in the Kumasi Metropolis. We purposively sampled 392 migrant female head porters in the Kejetia, Asafo and Bantama markets. We used a binary logit regression model to estimate associations among baseline characteristics, convenience and benefit factors and enrolment in and renewal and utilisation of the NHIS. Age and income significantly increased the probability of NHIS enrolment, renewal and utilisation. Long waiting times at NHIS offices significantly reduced the likelihood of renewal, while provision of drugs highly significantly increased the tendency for migrant female head porters to enrol in, renew and use the NHIS. Consulting and surgery also significantly increased renewal and utilisation of the NHIS. Political commitment is imperative for effective implementation of the decentralisation policy of the NHIS through the National Health Insurance Authority in Kumasi. We argue that retail offices should be well equipped with logistic facilities to ensure convenience in NHIS initial enrolment and renewal processes by citizenry, and by vulnerable groups in particular.

    Objectives To assess the health service utilisation of internal migrant children in Guangdong, China, and to explore the association between children’s health service utilisation and their parents’ acculturation. Design Cross-sectional survey between April and May 2016. Setting Six society-run schools of Tianhe and Baiyun districts in Guangzhou City of China. Participants We recruited all students at grade 7 or 8 and one of their parents who resided in Guangzhou over 6 months without permanent registered residence (hukou) in Guangzhou (1161 pairs completed this survey). 258 children were ill within the past 2 weeks or during the last year. Main outcome measures The main outcome was self-reported health service utilisation. Logistic regression analysis was conducted to explore the association between children’s unmet needs for outpatient or inpatient service and their parents’ acculturation (categorised into high, middle and low groups). Results In total, 216 children, or 18.6% of the total subjects, were ill within the past 2 weeks and were in need of outpatient service; 94 children, or 8.1% of the total subjects, were in need of inpatient service. Among them, 17.6% and 46.8% of the migrant children had unmet needs for outpatient and inpatient services, respectively. After controlling for enabling resources and predisposing characteristics, migrant children with parents in the middle-acculturation group (adjusted OR=3.17, 95% CIs 1.2 to 8.3, Pacculturation or low-acculturation groups, although only statistically significant when comparing with the high-acculturation group. Stratified analysis suggested that this association could be moderated by their family economic status. Conclusions Our study suggested that the association between migrant children’s health service utilisation and their parents’ acculturation was complex and could be moderated by family economic status. Increasing the service utilisation among migrant children requires

    Scant research is available on the impact of the current economic crisis and austerity policies on inequality in health services utilisation in Europe. This study aimed to describe the trends in horizontal inequity in the use of health services in Andalusia, Spain, during the early years of the Great Recession, and the contribution of demographic, economic and social factors. Consultation with a general practitioner (GP) and specialist, hospitalisation and emergency care were studied through the Andalusian Health Survey 2007 (pre-crisis) and 2011-2012 (crisis), using a composite income index as socioeconomic status (SES) indicator. Horizontal inequity indices (HII) were calculated to take differential healthcare needs into account, and a decomposition analysis of change in inequality between periods was performed. Results showed that before the crisis, the HII was positive (greater access for people with higher SES) for specialist visits but negative (greater access for people with lower SES) in the other three utilisation models. During the crisis no change was observed in inequalities in GP visits, but a pro-poor development was seen for the other types of utilisation, with hospital and emergency care showing significant inequality in favour of low income groups. Overall, the main contributors to pro-poor changes in utilisation were socio-economic variables and poor mental health, due to changes in their elasticities. Our findings show that inequalities in healthcare utilisation largely remained in favour of the less well-off, despite the cuts in welfare benefits and health services provision during the early years of the recession in Andalusia. Further research is needed to monitor the potential impact of such measures in subsequent years.

  3. Assessing potential forest and steel inter-industry residue utilisation by sequential chemical extraction

    2012-10-15

    Traditional process industries in Finland and abroad are facing an emerging waste disposal problem due recent regulatory development which has increased the costs of landfill disposal and difficulty in acquiring new sites. For large manufacturers, such as the forest and ferrous metals industries, symbiotic cooperation of formerly separate industrial sectors could enable the utilisation waste-labeled residues in manufacturing novel residue-derived materials suitable for replacing commercial virgin alternatives. Such efforts would allow transforming the current linear resource use and disposal models to more cyclical ones and thus attain savings in valuable materials and energy resources. The work described in this thesis was aimed at utilising forest and carbon steel industry residues in the experimental manufacture of novel residue-derived materials technically and environmentally suitable for amending agricultural or forest soil properties. Single and sequential chemical extractions were used to compare the pseudo-total concentrations of trace elements in the manufactured amendment samples to relevant Finnish statutory limit values for the use of fertilizer products and to assess respective potential availability under natural conditions. In addition, the quality of analytical work and the suitability of sequential extraction in the analysis of an industrial solid sample were respectively evaluated through the analysis of a certified reference material and by X-ray diffraction of parallel sequential extraction residues. According to the acquired data, the incorporation of both forest and steel industry residues, such as fly ashes, lime wastes, green liquor dregs, sludges and slags, led to amendment liming capacities (34.9-38.3%, Ca equiv., d.w.) comparable to relevant commercial alternatives. Only the first experimental samples showed increased concentrations of pseudo-total cadmium and chromium, of which the latter was specified as the trivalent Cr(III). Based on

    The paper presents utilisation of the VR-1 reactor for nuclear education and training at national and international level. VR-1 reactor has been operating by the Czech Technical University since December 1990. The reactor is a pool-type light water reactor based on enriched uranium (19.7% 235 U) with maximum thermal power 1kW and for short time period up to 5kW. The moderator of neutrons is light water, which is also used as a reflector, a biological shielding and a coolant. Heat is removed from the core by natural convection. The pool disposition of the reactor facilitates access to the core, setting and removing of various experimental samples and detectors, easy and safe handling of fuel assemblies. The reactor core can contain from 17 to 21 fuel assemblies IRT-4M, depending on the geometric arrangement and kind of experiments to be performed in the reactor. The reactor is equipped with several experimental devices; e.g. horizontal, radial and tangential channels used to take out a neutron beam, reactivity oscillator for dynamics study and bubble boiling simulator. The reactor has been used very efficiently especially for education and training of university students and NPP's specialists for more than 18 years. The VR-1 reactor is utilised within various national and international activities such as Czech Nuclear Education Network (CENEN), European Nuclear Education Network and also Eastern European Research Reactor Initiative (EERRI). The reactor is well equipped for education and training not only by the experimental facility itself but also by incessant development of training methods and improvement of education experiments. The education experiments can be combined into training courses attended by students according to their study specialization and knowledge level. The training programme is aimed to the reactor and neutron physics, dosimetry, nuclear safety, and control of nuclear installations. Every year, approximately 250 university students undergo

    Heating and cooling have a major role in the energy sector, covering 46% of total final energy use worldwide. District heating (DH) is a significant technology for improving the energy efficiency of heating systems in communities, because it enables waste heat sources to be utilised economically and therefore significantly reduces the environmental impacts of power generation. As a result of new and more stringent construction regulations for buildings, the heat demands of individual buildings are decreasing and more energy-efficient heating systems have to be developed. In this study, the energy efficiency of a new DH system which includes both a new control system called mass flow control and a new network design called a ring network is examined. A topology in the Helsinki region is studied by using a commercial DH network modelling tool, Grades Heating. The district heating network is attached to a wood-burning heat station which has a heat recovery system in use. Examination is performed by means of both technical and economic analysis. The new non-linear temperature programme that is required is adopted for supply and return temperatures, which allows greater temperature cooling and smaller flow rates. Lower district heating water temperatures are essential when reducing the heat losses in the network and heat production. Mass flow control allows smaller pressure drops in the network and thus reduces the pumping power. The aim of this study was to determine the most energy-efficient DH water supply temperatures in the case network. If the ring network design is utilised, the district heating system is easier to control. As a result the total heat consumption within the heating season is reduced compared to traditional DH systems. On the basis of the results, the new DH system is significantly more energy-efficient in the case network that was examined than the traditional design. For example, average energy losses within the constraints (which consist of heat

    Military body armour is designed to prevent the penetration of ballistic projectiles into the most vulnerable structures within the thorax and abdomen. Currently the OSPREY and VIRTUS body armour systems issued to United Kingdom (UK) Armed Forces personnel are provided with a single size front and rear ceramic plate regardless of the individual's body dimensions. Currently limited information exists to determine whether these plates overprotect some members of the military population, and no method exists to accurately size plates to an individual. Computed Tomography (CT) scans of 120 male Caucasian UK Armed Forces personnel were analysed to measure the dimensions of internal thoraco-abdominal anatomical structures that had been defined as requiring essential medical coverage. The boundaries of these structures were related to three potential anthropometric landmarks on the skin surface and statistical analysis was undertaken to validate the results. The range of heights of each individual used in this study was comparable to previous anthropometric surveys, confirming that a representative sample had been used. The vertical dimension of essential medical coverage demonstrated good correlation to torso height (suprasternal notch to iliac crest) but not to stature (r(2)=0.53 versus 0.04). Horizontal coverage did not correlate to either measure of height. Surface landmarks utilised in this study were proven to be reliable surrogate markers for the boundaries of the underlying anatomical structures potentially requiring essential protection by a plate. Providing a range of plate sizes, particularly multiple heights, should optimise the medical coverage and thus effectiveness of body armour for UK Armed Forces personnel. The results of this work provide evidence that a single width of plate if chosen correctly will provide the essential medical coverage for the entire military population, whilst recognising that it still could overprotect the smallest individuals

    Obesity is not only a health problem but also a source of increased monetary expenditures. The objectives of this study were to analyse the use of healthcare resources in the Spanish adult population with class II obesity and above (BMI ≥35 kg/m 2 ) and to compare it with other BMI groups. We used the Spanish National Health Survey, a longitudinal population-based survey (n = 18,682), to analyse healthcare resource utilisation by BMI groups. Adjusted and unadjusted logistic regression models were used to calculate odds ratios (OR) for healthcare use among class II and over obese subjects versus normal BMI. Persons with BMI ≥35 are more likely to attend general practitioner (GP)'s consultations (17%), to visit the emergency department (26%), to consume medications (36%), to be hospitalised (49%), to require nursing consultations (61%) and to require psychology consultations (83%). The proportion of obese people receiving home visits is 2.6 times higher than among normal BMI. After controlling for sex and age groups, people with severe obesity (BMI ≥35 kg/m 2 ) were more prone to requiring home care visits (OR 2.3; CI [1.3; 4.2]), GP visits (OR 2.1; CI [1.5; 3.0]), psychologist visits (OR 1.96; CI [1.3; 2.99]), emergency service visits (OR 1.5; CI [1.2; 1.8]), nurse visits (OR 1.46; CI [1.2; 1.9]) and hospitalisations (OR 1.43; CI [1.1; 1.9]) and after also adjusting for relevant comorbidities like hypertension, diabetes and cardiovascular diseases: GP visits (OR 1.85; CI [1.3; 2.7]), psychologist visits (OR 1.8; CI [1.2; 2.7]), specialised care visits (OR 0.92; CI [0.7; 1.2]) and physiotherapist visits (OR 0.7; CI [0.5; 1.0]). Severe obesity significantly increases healthcare resource utilisation in Spain. The results shed light on the real magnitude of the burden of obesity in Spain.

    Full Text Available Aim/Purpose: Facebook has made it possible for organisation to embrace social and network centric knowledge processes by creating opportunities to connect, interact, and collaborate with stakeholders. We have witnessed a significant increase in the popularity and use of this tool in many organisations, especially in the private sector. But the utilisation of Facebook in public organisations is at its infancy, with many also believing that the use of Facebook is not a common practice in many public organisations in Nigeria. In spite of this fact, our discernment on the implications of Facebook usage in public organisations in Nigeria, especially organisations at the local level, seem to be remarkably limited. This paper specifically sought to ascertain if Facebook usage influenced inward and outward knowledge sharing in the selected local government councils in Delta State, Nigeria Methodology: The qualitative method was adopted. The study used interview as the primary means of data gathering. The study purposively sampled thirty-six employees as interviewees, twenty from Oshimili South and sixteen from Oshimili North local government councils respectively. The thematic content analysis method was used to analyse interview transcripts. Contribution: This research made distinct contributions to the available literature in social knowledge management, specifically bringing to the fore the intricacies surrounding the use of Facebook for knowledge sharing purposes in the public sector. Findings: The local government councils were yet to appreciate and utilise the interactive and collaborative nature of Facebook in improving stakeholders’ engagement, feedback, and cooperation. Facebook was used for outward knowledge sharing but not for inward knowledge sharing. Recommendations for Practitioners: Local government councils should encourage interaction via Facebook, show willingness to capture knowledge from identifiable sources, and effectively manage

    Indium tin oxide (ITO) films were deposited by reactive High Target Utilisation Sputtering (HiTUS) onto glass and polyimide substrates. The ion plasma was generated by an RF power source while the target bias voltage was varied from 300 V to 500 V using a separate DC power supply. The deposition rate, at constant target power, increased with DC target voltage due to increased ion energy reaching 34 nm/min at 500 V. All the films were polycrystalline and showed strong (400) and (222) reflections with the relative strength of latter increasing with target bias voltage. The resistivity was lowest at 500 V with values of 1.8 x 10 -4 Ω cm and 2.4 x 10 -4 Ω cm on glass and polyimide, respectively but was still less than 5 x 10 -4 Ω cm at 400 V. All films were highly transparent to visible light, (> 80%) but the NIR transmittance decreased with increasing target voltage due to higher free carrier absorption. Therefore, ITO films can be deposited onto semiconductor layers such as in solar cells, with minimal ion damage while maintaining low resistivity

    Indium tin oxide (ITO) films were deposited on soda lime glass and polyimide substrates using an innovative process known as High Target Utilisation Sputtering (HiTUS). The influence of the oxygen flow rate, substrate temperature and sputtering pressure, on the electrical, optical and thermal stability properties of the films was investigated. High substrate temperature, medium oxygen flow rate and moderate pressure gave the best compromise of low resistivity and high transmittance. The lowest resistivity was 1.6 x 10 -4 Ω cm on glass while that on the polyimide was 1.9 x 10 -4 Ω cm. Substrate temperatures above 100 deg. C were required to obtain visible light transmittance exceeding 85% for ITO films on glass. The thermal stability of the films was mainly influenced by the oxygen flow rate and thus the initial degree of oxidation. The film resistivity was either unaffected or reduced after heating in vacuum but generally increased for oxygen deficient films when heated in air. The greatest increase in transmittance of oxygen deficient films occurred for heat treatment in air while that of the highly oxidised films was largely unaffected by heating in both media. This study has demonstrated the potential of HiTUS as a favourable deposition method for high quality ITO suitable for use in thin film solar cells

    Currently, two food sufficiency questions are utilised as a proxy measure of national food security status in Australia. These questions do not capture all dimensions of food security and have been attributed to underreporting of the problem. The purpose of this study was to investigate food security using the short form of the US Household Food Security Survey Module (HFSSM) within an Australian context; and explore the relationship between food security status and multiple socio-demographic variables. Two online surveys were completed by 2334 Australian participants from November 2014 to February 2015. Surveys contained the short form of the HFSSM and twelve socio-demographic questions. Cross-tabulations chi-square tests and a multinomial logistic regression model were employed to analyse the survey data. Food security status of the respondents was classified accordingly: High or Marginal (64%, n = 1495), Low (20%, n = 460) or Very Low (16%, n = 379). Significant independent predictors of food security were age (P important issue across Australia and that certain groups, regardless of income, are particularly vulnerable. Government policy and health promotion interventions that specifically target "at risk" groups may assist to more effectively address the problem. Additionally, the use of a multi-item measure is worth considering as a national indicator of food security in Australia. © 2018 Australian Health Promotion Association.

  15. Implication of changing loading conditions on structural health monitoring utilising guided waves

    Structural health monitoring systems based on guided waves typically utilise a network of embedded or permanently attached sensors, allowing for the continuous detection of damage remote from a sensor location. The presence of damage is often diagnosed by analysing the residual signals from the structure after subtracting damage-free reference data. However, variations in environmental and operational conditions such as temperature, humidity, applied or thermally-induced stresses affect the measured residuals. A previously developed acoustoelastic formulation is here extended and employed as the basis for a simplified analytical model to estimate the effect of applied or thermally-induced stresses on the propagation characteristics of the fundamental Lamb wave modes. It is noted that there are special combinations of frequency, biaxial stress ratio and direction of wave propagation for which there is no change in the phase velocity of the fundamental anti-symmetric mode. The implication of these results in devising effective strategies to mitigate the effect of stress induced variations in guided-wave damage diagnostics is briefly discussed.

    Full Text Available The detection of anti-hepatitis A virus (HAV antibody levels by diagnostic kits in the convalescent period of disease generally use immunoglobulin G (IgG, which is expensive. An alternative to IgG is immunoglobulin Y (IgY, an immunoglobulin antibody encountered in birds and reptiles. The aim of this study was to develop a competitive immunoenzymatic assay to measure total anti-HAV antibody levels using anti-HAV IgY as the capture and conjugated immunoglobulins. For this purpose, anti-HAV IgY was conjugated to horseradish peroxidase (HRP and the optimal dilution of HRP-conjugated antibodies was evaluated to establish the competitive immuneenzymatic assay. The results obtained from our "in-house" assay were plotted on a receiver operator curve, which showed a sensitivity of 95% and a specificity of 98.8%, demonstrating that a competitive anti-HAV IgY immunoenzymatic assay developed "in house" could be used as an alternative to commercial assays that utilise IgG.

    Over a period of 4 days 15 N-lysine was infused into two growing female pigs (live weight approximately 50 kg) through a cecal cannula. The feeding was restrictive (1,400 g dry matter/day) and, with regard to lysine, it did not meet the requirements. In a 7-days experiment the N and 15 N content was measured periodically in feces and urine, in various fractions of the blood and in selected slaughtering samples. From the 15 N infused 3-5% were excreted as lysine in the feces, another 5% were in other amino acids of the bacterial protein. The disappearance rate of 15 N' from the large intestine was >= 90%. 78-88% of this 15 N' was excreted with the urine in form of 15 N-urea. Obviously the infused amino acid was decomposed to NH 3 in the large intestine and then absorbed. The absorbed ammonia was changed into urea in the ornithine cycle and excreted in urine. The recovery rate of the 15 N infused as 15 N-lysine was 93 and 84%, resp. Incorporation of 15 N in to serum protein or other body protein could not be detected so that the remaining difference of 7-16% cannot necessarily be interpreted as incorporation rate of 15 N into the body protein. Under practical conditions the maximal utilisation of lysine from the feed in the large intestine is 1.6% and should be inconsiderable

    The birth of a nuclear industry has permitted the use of radioelements in an increasing number of domains. Currently, the majority of radioelements applications in industrial problematic are essentially on nondestructive control and on problems of static electricity, as well as in a least way for the use of the intense radiation sources, on agronomic problems, for hydrology or chemical analyses. In order to promote the industrial applications, The CEA took to this purpose several sets of decisions: 1 - institution of teachings and collaboration; 2 - encourage the constructors of devices; 3 - creation of a help service to the users.

    Chronic sulphonylurea treatment maintains improved glycaemic control through mechanisms other than enhancement of insulin secretion and may act on various organs. The aim of this study was to investigate whether the chronic use of sulphonylurea drugs influences PET measurement of myocardial glucose utilisation (MGU) in type II diabetes mellitus. Forty-two patients with type II diabetes mellitus and 17 control subjects underwent dynamic 18 F-FDG PET to measure MGU during hyperinsulinaemic euglycaemic clamping. Twenty-one patients had been taking sulphonylurea drugs for more than 1 year (SU group), and the other 21 patients were drug naive (non-SU group). The haemoglobin A1c levels in the two patient groups were similar. Glucose disposal rate (GDR) was also determined as a marker of whole-body insulin resistance. GDR in the SU group (9.01±2.53 mg min -1 kg -1 ) was significantly higher than that in the non-SU group (4.10±2.47, p -1 100 g -1 ) was significantly higher than that in the non-SU group (5.53±2.05, p<0.01) and was similar to that in the controls (7.49±2.74).

    Although racism has been posited as driver of racial/ethnic inequities in healthcare, the relationship between racism and health service use and experience has yet to be systematically reviewed or meta-analysed. This paper presents a systematic review and meta-analysis of quantitative empirical studies that report associations between self-reported racism and various measures of healthcare service utilisation. Data were reviewed and extracted from 83 papers reporting 70 studies. Studies included 250,850 participants and were conducted predominately in the U.S. The meta-analysis included 59 papers reporting 52 studies, which were analysed using random effects models and mean weighted effect sizes. Racism was associated with more negative patient experiences of health services (HSU-E) (OR = 0.351 (95% CI [0.236,0.521], k = 19), including lower levels of healthcare-related trust, satisfaction, and communication. Racism was not associated with health service use (HSU-U) as an outcome group, and was not associated with most individual HSU-U outcomes, including having had examinations, health service visits and admissions to health professionals and services. Racism was associated with health service use outcomes such as delaying/not getting healthcare, and lack of adherence to treatment uptake, although these effects may be influenced by a small sample of studies, and publication bias, respectively. Limitations to the literature reviewed in terms of study designs, sampling methods and measurements are discussed along with suggested future directions in the field. PMID:29253855

    PURPOSE: Spinal fusion surgery rates in the elderly are increasing. Cost effectiveness analyses with relatively short-length follow-up have been performed. But the long-term effects in terms of health care use are largely unknown. The aim of the present study was to describe the long......-term consequences of spinal fusion surgery in elderly patients on health care use and costs using a health care system perspective. METHODS: 194 patients undergoing spinal fusion between 2001 and 2005 (70 men, 124 women) with a mean age of 70 years (range 59-88) at surgery were included. Average length of follow......-up was 6.2 years (range 0.3-9.0 years). Data on resource utilisation and costs were obtained from national registers providing complete coverage of all reimbursed contacts with primary- and secondary health care providers. Data were available from 3 years prior fusion surgery until the end of 2009. RESULTS...

    The research question addressed in this paper is how different reference amounts utilised in front of package nutrition labelling influence evaluation of product healthfulness. A total of 13,117 participants from six European countries (Germany, UK, Spain, France, Poland and Sweden) were recruited via online panels. A mixed between/within-subject factorial design was employed with food (biscuits, sandwiches, yogurts), healthfulness and presence of Guideline Daily Amounts as within-subjects factors and reference amount ('per 100 g', 'typical portion', 'half portion') and country as between-subjects factors. Overall, people correctly ranked foods according to their objective healthfulness as defined by risk nutrients alone, and could distinguish between more and less healthful variants of foods. General healthfulness associations with the three product categories do not appear to have had a strong influence on product ratings. This study shows that where the reference amount of 'per 100 g' is very different from the 'typical' portion size, as was the case for biscuits, products with a 'per 100 g' label are rated significantly less healthful than the 'typical' or 'half typical' portions. The results indicate that across the three food categories, consumers do factor the reference amount, that is, the quantity of food for which the nutritional information is being presented, into their judgements of healthfulness. Therefore, appropriate reference amounts are also of importance for the effective presentation of nutritional information.

  3. Energy utilisation of biowaste - Sunflower-seed hulls for co-firing with coal

    Sunflower-seed hulls (SSH) represent a source of combustible biomass characterised by high contents of potassium and phosphorus and a low silica content. The relatively high net calorific value of 20 MJ/kg d.m. is mainly influenced by the lignin content. Potassium and phosphorus are very important elements in biomass combustion for fuel, influencing slagging and fouling problems. Mixtures with different ratios of brown coal and sunflower-seed hulls (0-22% SSH) were co-fired in the Olomouc power plant. The behaviour of elements in the fly ash and the bottom ash (SiO{sub 2}, Al{sub 2}O{sub 3}, K{sub 2}O, P{sub 2}O{sub 5}, Zn, Cu and Cd) varied in relation to the amount of SSH added to the coal. The fly ash from the co-firing of 20% SSH with coal had a high content of water-leachable sulphates and total dissolved solids. The utilisation of fly ash in civil engineering (land reclamation) should fulfil criteria established by the Council Decision 2003/33/EC for non-hazardous waste. To ensure that the required water-leachable sulphate concentrations are within regulatory limits the fuel may contain a maximum of 14% SSH. (author)

    Full Text Available L'utilisation des eaux usées en pisciculture nécessite un traitement minimum indispensable (lagunage, épuration classique, prédilution, dilution simultanée. Une deuxième condition, non moins importante, est la sélection exclusive des eaux usées domestiques et rurales afin d'éviter la présence de métaux lourds et autres substances toxiques des rejets industriels. Dans un tel milieu enrichi, la production piscicole peut être doublée et même triplée sans nourriture additionnelle. Cependant, même si on arrive à de bons résultats, certains dangers subsistent : possibilité d'anoxie due à la dégradation des matières organiques, présence d'ammoniac, de nitrites, de détergents, risques d'infections virales et bactériennes. Des études ultérieures devraient préciser ces problèmes et tenter de les résoudre.

  5. Towards a utilisation of transient processing in the technology of high efficiency silicon solar cells

    1989-01-01

    The utilization of transient processing in the technology of high efficient silicon solar cells is investigated. An ultraviolet laser (an ArF pulsed excimer laser working at 193 nm) is applied. Laser processing induces only a short superficial melting of the material and does not modify the transport properties in the base of the material. This mode of processing associated to ion implantation to form the junction as well as an oxide layer in an atmosphere of oxygen. The volume was left entirely cold in this process. The results of the investigation show: that an entirely cold process of solar cell fabrication needs a thermal treatment at a temperature around 600 C; that the oxides obtained are not satisfying as passivating layers; and that the Rapid Thermal Processing (RTP) induced recombination centers are not directly related to the quenching step but a consequence of the presence of metal impurities. The utilisation of transient processing in the adiabatic regime (laser) and in the rapid isothermal regime (RTP) are possible as two complementary techniques for the realization of high efficiency solar cells

    The presence of copper in wine is known to impact the reductive, oxidative and colloidal stability of wine, and techniques enabling measurement of different forms of copper in wine are of particular interest in understanding these spoilage processes. Electrochemical stripping techniques developed to date require significant pretreatment of wine, potentially disturbing the copper binding equilibria. A thin mercury film on a screen printed carbon electrode was utilised in a flow system for the direct analysis of labile copper in red and white wine by constant current stripping potentiometry with medium exchange. Under the optimised conditions, including an enrichment time of 500s and constant current of 1.0μA, the response range was linear from 0.015 to 0.200mg/L. The analysis of 52 red and white wines showed that this technique generally provided lower labile copper concentrations than reported for batch measurement by related techniques. Studies in a model system and in finished wines showed that the copper sulfide was not measured as labile copper, and that loss of hydrogen sulfide via volatilisation induced an increase in labile copper within the model wine system.

    Characterisation of a composition of Lead Barium Zirconate thin films deposited by a spin coating sol-gel process onto platinised silicon substrates has been undertaken to investigate a potential application utilising the reported electrocaloric properties of the material. Xray diffraction studies revealed that above 700 °C the presence of pyrochlore phase was replaced by ferroelectric phase but the identification of antiferroelectric phases previously reported could not be identified. Wet etching of the films produced an insoluble residue containing only evidence of zirconium out of the original three metals, which resembled a skeletal structure similar to the original rosette morphology of the annealed films. Elemental analysis of the annealed films using EDX indicated a non-target Pb:Ba:Zr ratio, which suggested a reduced Zr content of the films. “Solution-like” rather than “sol-like” nature of the spin coated sol and phase boundary proximity are proposed for reported observations, and a mechanism is proposed to account for the unusual observed trend in dielectric constant. - Highlights: • Characterisation of sol-gel deposited Lead barium zirconnate films. • Absence of previously reported antiferroelectric phase. • Identification of proposed non-PBZ phase. • Anomalous increase in film capacitance with thickness interpreted.

    With the promotion of environmental protection in the construction industry, the mission to achieve more sustainable use of resources during the production process of concrete is also becoming important. This study was conducted to assess the environmental sustainability of concrete slurry waste (CSW) management by life cycle assessment (LCA) techniques, with the aim of identifying a resource-efficient solution for utilisation of CSW in the production of partition wall blocks. CSW is the dewatered solid residues deposited in the sedimentation tank after washing out over-ordered/rejected fresh concrete and concrete trucks in concrete batching plants. The reuse of CSW as recycled aggregates or a cementitious binder for producing partition wall blocks, and the life cycle environmental impact of the blocks were assessed and compared with the conventional one designed with natural materials. The LCA results showed that the partition wall blocks prepared with fresh CSW and recycled concrete aggregates achieved higher sustainability as it consumed 59% lower energy, emitted 66% lower greenhouse gases, and produced lesser amount of other environmental impacts than that of the conventional one. When the mineral carbonation technology was further adopted for blocks curing using CO 2 , the global warming potential of the corresponding blocks production process was negligible, and hence the carbonated blocks may be considered as carbon neutral eco-product.

    Six parenteral third generation cephalosporins have been introduced into clinical use in the past 10 years. The 3 most frequently available agents are cefotaxime, ceftriaxone and ceftazidime. These 3 third generation cephalosporins are characterised by a broad spectrum of activity and increased stability to beta-lactamases compared with the first and second generation cephalosporins. However, there are growing numbers of reports of resistance to these agents with increasing use. The major differences in the properties of the 3 agents are the long half-life of ceftriaxone and its dual route of elimination. Ceftazidime is best restricted to Pseudomonas aeruginosa infections where other agents are contraindicated or ineffective. Cefotaxime and ceftriaxone can be used in nosocomial Gram-negative infections where P. aeruginosa can be ruled out. The types and incidences of adverse drug reactions are not different for the 3 agents. A number of drug utilisation review (DUR) studies of these agents in the hospital setting have reported a considerable incidence of inappropriate use and substantial avoidable costs. There are methodological problems with most of the DUR studies, especially the criteria and the methods of cost estimation. The use of pharmacoeconomic methodology could ensure more realistic cost estimation; however, outcome data are, in most cases, not available.

    Magnetorheological elastomer (MRE) base isolations have attracted considerable attention over the last two decades thanks to its self-adaptability and high-authority controllability in semi-active control realm. Due to the inherent nonlinearity and hysteresis of the devices, it is challenging to obtain a reasonably complicated mathematical model to describe the inverse dynamics of MRE base isolators and hence to realise control synthesis of the MRE base isolation system. Two aims have been achieved in this paper: i) development of an inverse model for MRE base isolator based on optimal general regression neural network (GRNN); ii) numerical and experimental validation of a real-time semi-active controlled MRE base isolation system utilising LQR controller and GRNN inverse model. The superiority of GRNN inverse model lays in fewer input variables requirement, faster training process and prompt calculation response, which makes it suitable for online training and real-time control. The control system is integrated with a three-storey shear building model and control performance of the MRE base isolation system is compared with bare building, passive-on isolation system and passive-off isolation system. Testing results show that the proposed GRNN inverse model is able to reproduce desired control force accurately and the MRE base isolation system can effectively suppress the structural responses when compared to the passive isolation system.

    Corrective surgery for congenital heart disease may be life-saving, but its utilisation depends upon several social and economic factors. Girls with cardiac defects may not receive equitable care in India, but this has not been systematically studied. In this prospective study, parents or guardians of 405 consecutive children aged up to 12 years (mean ± SD age 3.43 ± 3.44 years; 271 boys) who had been advised to undergo elective paediatric cardiac surgery were interviewed using a validated questionnaire. The status of the patients was reviewed after a year and the factors associated with non-compliance with treatment were analysed. In a qualitative sub-study the parents of 20 children who had not undergone surgery were interviewed. Qualitative data were analysed using an inductive analytical approach. Of the 405 patients studied, 44% (59/134) of girls had undergone surgery at 1 year compared with 70% (189/271) of boys (χ²=24.97; pmatrimonial prospects of girls and lack of social support emerged as the major factors responsible for delays in undergoing surgery. Female gender is an important determinant of non-compliance with paediatric cardiac surgery. Deep-seated social factors underlie this gender bias.

    Small scale biomass gasification is a sector with growth and increasing applications owing to the environmental goals of the European Union and the incentivised policies of most European countries. This study addresses two aspects, which are at the centre of attention concerning the operation and development of small scale gasifiers; reuse of waste and increase of energy efficiency. Several authors have denoted that the low electrical efficiency of these systems is the main barrier for further commercial development. In addition, gasification has several by-products that have no further use and are discarded as waste. In the framework of this manuscript, a secondary reactor is introduced and modelled. The main operating principle is the utilisation of char and flue gases for further energy production. These by-products are reformed into secondary producer gas by means of a secondary reactor. In addition, a set of heat exchangers capture the waste heat and optimise the process. This case study is modelled in a MATLAB-Cantera environment. The model is non-stoichiometric and applies the Gibbs minimisation principle. The simulations show that some of the thermal energy is depleted during the process owing to the preheating of flue gases. Nonetheless, the addition of a secondary reactor results in an increase of the electrical power production efficiency and the combined heat and power (CHP) efficiency. © The Author(s) 2016.

    Full Text Available Background: Managers’ organisational decisions and subsequent actions flow from their understanding of the business environment in which they operate. This study sought to understand how managers in various organisations identify, evaluate and use information for effective current and future decision-making. Objectives: The study focused on the types of information needed by managers for decision-making, the methods used to identify and acquire the information and the sources of information consulted, their satisfaction with the information used and their decision-making behaviours. Methods: The study employed descriptive study design. Simple random sampling was used. A pre-tested self-administered questionnaire was used to gather information from 219 managers, randomly selected from the registers of the Ibadan, Abeokuta and Lagos chapters of Nigerian Institute of Management. Results: Results indicated that the types of information considered very important for decision-making included industry information followed by government policies and economic development/forecasts. Conclusion: Investigation revealed the extent of information identification, information evaluation and information utilisation individually predict the perceived effectiveness of decision-making by the managers. Nevertheless, information evaluation was found to have greater predictive relationship with perceived effectiveness of decision-making than information use and information identification.

    The milling of oil palm fruits produces about two-and-a-half to three times as much effluent as oil does. It also generates a large amount of lignocellulosic wastes, mainly in the form of empty fruit bunches, press cake fibres and nut shell. Research efforts at PORIM have been directed towards the utilisation of these wastes as a means to solve the problem of environmental pollution as well as for the generation of economic returns for the mills. We have studied a thermophilic contact process for the anaerobic digestion of palm oil mill effluent and its potential for generating biogas for energy uses. Our work has also shown that the condensate derived from the fruit sterilisation process during milling is amenable to fermentation for the production of single cell protein (SCP) and exo-enzymes. The enzymes produced have been applied for oil clarification, oil recovery from press cake fibers and saccharification of the fibers for the production of sugar feedstocks. This paper will also introduce the concept of integrated waste management for the palm oil mill through the implementation of these technologies.

    The objective of this study was to identify the predictors of utilisation of dental care services in Ireland. The 2007 Irish Survey of Lifestyle, Attitudes and Nutrition is a cross-sectional study, conducted in 2006/2007 (n = 10,364), by interviews at home to a representative sample of adults aged 18 years or over. Multivariate logistic regression was used to investigate the influence of socioeconomic, predisposing and enabling factors on the odds of males and females having a dental visit in the past year. The significant predictors of visiting the dentist in the past year were for males: having 3rd level education, employment status, earning 50,000 euros or more, location of residence, use of a car, brushing frequently, and dentition status. For females, the predictors were being between 25-34 or 55-64 years-old, education level, earning 50,000 euros or more, location of residence, use of a car, brushing frequently and dentition status. Predictors of the use of dental services vary by gender. Predictors common to both genders were education level, higher income, location of residence, use of a car, brushing frequently and dentition status. Many of the predictors of dental visiting in the past year are also related to social inequalities in health. These predictors may be useful markers of impact for policies designed to address inequalities in access to oral health services.

    Although racism has been posited as driver of racial/ethnic inequities in healthcare, the relationship between racism and health service use and experience has yet to be systematically reviewed or meta-analysed. This paper presents a systematic review and meta-analysis of quantitative empirical studies that report associations between self-reported racism and various measures of healthcare service utilisation. Data were reviewed and extracted from 83 papers reporting 70 studies. Studies included 250,850 participants and were conducted predominately in the U.S. The meta-analysis included 59 papers reporting 52 studies, which were analysed using random effects models and mean weighted effect sizes. Racism was associated with more negative patient experiences of health services (HSU-E) (OR = 0.351 (95% CI [0.236,0.521], k = 19), including lower levels of healthcare-related trust, satisfaction, and communication. Racism was not associated with health service use (HSU-U) as an outcome group, and was not associated with most individual HSU-U outcomes, including having had examinations, health service visits and admissions to health professionals and services. Racism was associated with health service use outcomes such as delaying/not getting healthcare, and lack of adherence to treatment uptake, although these effects may be influenced by a small sample of studies, and publication bias, respectively. Limitations to the literature reviewed in terms of study designs, sampling methods and measurements are discussed along with suggested future directions in the field.

    To investigate the utilisation, reliability and validity of clinical evaluation exercise (CEX) in otolaryngology training. Retrospective database analysis. Online assessment database. We analysed all CEXs submitted by north London core (CT) and speciality trainees (ST) in otolaryngology from 2010 to 2013. Internal consistency of the 7 CEX items rated as either O: outstanding, S: satisfactory or D: development required. Overall performance rating (pS) of 1-4 assessed against completion of training level. Receiver operating characteristic was used to describe CEX sensitivity and specificity. Overall score (cS), pS and the number of 'D'-rated items were used to investigate construct validity. One thousand one hundred and sixty CEXs from 45 trainees were included. CEX showed good internal consistency (Cronbach's alpha= 0.85). CEX was highly sensitive (99%), yet not specific (6%). cS and pS for ST was higher than CT (99.1% ± 0.4 versus 96.6% ± 0.8 and 3.06 ± 0.05 versus 1.92 ± 0.04, respectively P reliable in assessing early years otolaryngology trainees in clinical examination, but not at higher level. It has the potential to be used in a summative capacity in selecting trainees for ST positions. This would also encourage trainees to master all domains of otolaryngology clinical examination by end of CT. © 2015 John Wiley & Sons Ltd.

    Full Text Available Status epilepticus (SE is a medical emergency and it is associated to brain damage. 2-deoxy-[14C] glucose (2-DG procedure has been used to measure the alterations in the functional activity of the brain induced by various pharmacological and toxicological agents. The aim of this study was to determine which changes occur in the seizure anatomic substrates during the SE induced by pilocarpine (PILO using [14C]-2 deoxyglucose functional mapping technique. Wistar male adult rats were submitted to SE PILO-induced for 6h and received [14C] 2-deoxyglucose injection via jugular vein 45 min before the 6th hour of SE. The control animals were submitted to all procedures but received saline and not pilocarpine. Brain sections were prepared and exposed X-ray film about seven days. The optical density of each region was obtained using a solid state digital analyser. The analysis revealed that 14C-2DG utilisation was pronounced in the SE rats on the areas corresponding to the hippocampal formation (+50.6%, caudate-putamen (+30.6%, frontoparietal cortex (+32.2%, amygdala (+31.7%, entorrinal cortex (+28.2%, thalamic nucleus (+93.5%, pre-tectal area (+50.1% and substantia nigra (+50.3% when compared to control. Our results suggest that the different activation levels of the distinct structures may be particularly important for understanding triggering and spreading mechanisms underlying epileptic activity during status epilepticus.

  19. The Spectral Shift Control Reactor as an option for much improved uranium utilisation in single-batch SMRs

    Highlights: • A PWR with mixed D{sub 2}O/H{sub 2}O moderator/coolant is investigated for SMR applications. • Heavy water concentration varied over the cycle to give ‘spectral shift’ operation. • Much wetter lattice than normal is neutronically favourable. • Taller fuel stack is thus needed to ensure acceptable MDNBR. • 35–43% increase in uranium utilisation for single batch reactor is possible. - Abstract: The Spectral Shift Control Reactor (SSCR) uses a mix of D{sub 2}O and H{sub 2}O to moderate and cool the reactor. Initially, a high proportion of D{sub 2}O is used, such that the reactor is substantially under-moderated, with excess neutrons being primarily captured in {sup 238}U, breeding {sup 239}Pu. Towards the end of the cycle (EOC), the coolant is predominantly H{sub 2}O, thermalising the neutron spectrum and increasing reactivity. Recently, small modular reactors (SMRs) have gained significant interest as a means of providing a power source that requires little maintenance and refuelling. This motivates long cycles and reduced batch operation. For a single-batch reactor, there is typically a 33% penalty to uranium utilisation compared to a 3-batch reactor. Lattice calculations demonstrate the potential of the SSCR to greatly improve uranium utilisation in single-batch reactors over a range of enrichments. A relatively ‘wet’ lattice is employed which further improves uranium utilisation. Cases with 5% and 15% fissile loading are considered, for which it is respectively possible to achieve 47% and 39% increases in natural uranium utilisation using the SSCR relative to a ‘reference’ light water reactor. In the latter case, if 25% thorium is mixed into the fuel, the improvement in uranium utilisation increases to a total of 49%. Hence, in both cases, it is possible to in effect eliminate the penalty of using a single fuel batch. The ‘wet’ lattice introduces substantial thermal-hydraulic challenges due to the significantly higher fuel

    2014-03-01

    Full Text Available The aim of the paper was to present the differences in the level and structure of utilisation of services in Polish and German agriculture. An attempt to define the factors influencing these values was also done. The research covered the share of agricultural services, veterinary expenses and financial intermediation services in intermediate consumption, the value of the studied services per 1 hectare of agricultural land, 1 AWU or 1 DJP, as well as services absorptivity of agricultural production. It was proved that although a significant difference between the role of these services in Poland and Germany still exists, in many cases in 2012 it was not so considerable as in 1998. It can be also assumed that further absorption of funds from the European Union will stimulate investment processes in Polish agriculture, and progressive improvement in utilisation of services by Polish agriculture.

    Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

    Full Text Available Automatic Guided Vehicles (AGVs are navigated utilising multiple types of sensors for detecting the environment. In this investigation such sensors are replaced and/or minimized by the use of a single omnidirectional camera picture stream. An area of interest is extracted, and by using image processing the vehicle is navigated on a set path. Reconfigurability is added to the route layout by signs incorporated in the navigation process. The result is the possible manipulation of a number of AGVs, each on its own designated colour-signed path. This route is reconfigurable by the operator with no programming alteration or intervention. A low resolution camera and a Matlab® software development platform are utilised. The use of Matlab® lends itself to speedy evaluation and implementation of image processing options on the AGV, but its functioning in such an environment needs to be assessed.

    The number of small-scale businesses within most national economies is generally high, especially in developing countries. Often these businesses have a weak economic status and limited environmental awareness. The type and amount of waste produced, and the recycling methods adopted by these businesses during their operation can have negative effects on the environment. This study investigated the types of waste generated and the recycling methods adopted in micro-sized enterprises engaged in the manufacture of furniture. An assessment was also made of whether the characteristics of the enterprise had any effect on the waste recycling methods that were practised. A survey was conducted of 31 enterprises in the furniture industry in Gumushane province, Turkey, which is considered a developing economy. Surveys were undertaken via face-to-face interviews. It was found that medium-density fibreboard (MDF), and to a lesser extent, chipboard, were used in the manufacture of furniture, and two major types of waste in the form of fine dust and small fragments of board are generated during the cutting of these boards. Of the resulting composite board waste, 96.9% was used for heating homes and workplaces, where it was burnt under conditions of incomplete combustion. Enterprises were found to have adopted other methods to utilise their wastes in addition to using them as fuel. Such enterprises include those operating from a basement or first floor of a building in the cities, those continuing production throughout the year, those in need for capital and those enterprises not operating a dust-collection system.

    Despite the impact of oral diseases on the quality of life, there is limited updated evidence on oral health status in Limpopo province. To determine the epidemiological profile of patients utilising public oral health services in Limpopo province. This was a descriptive retrospective clinical chart review conducted in five purposively selected district hospitals in Limpopo province. The collected data included the patient's sociodemographic information, reasons for dental consultation, information on the dental or oral diseases and the treatment received. Five hundred clinical files were systematically selected (100 from each district hospital) for the period 01 January 1995 to 31 December 2013. Data were collected using the World Health Organization's indicator age groups, namely 6-year-olds, 12-year-olds, 18-year-olds and 35-44-year-old groups. A data capturing sheet was used to record the collected information. Data were analysed using the statistical software package for social sciences SPSS version 23.0. The majority of patients were in the age group of 6 to 20 years (n = 375, 75%). The majority were male patients (n = 309; 62%). Dental caries was the most common complaint (n = 298, 60%). The second most common main complaint in this age group was retained primary or deciduous teeth (n = 60, 12%) affecting children mainly in the age group of 6 to 12 years. The most common clinical procedure across all five districts was dental extractions (n = 324, 64%). Other clinical interventions included scaling and polishing (n = 33, 12%) and dental restorative care (n = 20, 3%). There is an urgent need to reorient oral health service delivery in Limpopo province to focus more on preventive oral health programmes.

    Dementia is the fastest growing major cause of disability globally with a mounting social and financial impact for patients and their families but also to health and social care systems. This review aims to systematically synthesise evidence on the utilisation of resources and costs incurred by patients and their caregivers and by health and social care services across the full spectrum of dementia, from its preceding preclinical stage to end of life. The main drivers of resources used and costs will also be identified. A systematic literature review was conducted in MEDLINE, EMBASE, CDSR, CENTRAL, DARE, EconLit, CEA Registry, TRIP, NHS EED, SCI, RePEc and OpenGrey between January 2000 and beginning of May 2017. Two reviewers will independently assess each study for inclusion and disagreements will be resolved by a third reviewer. Data will be extracted using a predefined data extraction form following best practice. Study quality will be assessed with the Effective Public Health Practice Project quality assessment tool. The reporting of costing methodology will be assessed using the British Medical Journal checklist. A narrative synthesis of all studies will be presented for resources used and costs incurred, by level of disease severity when available. If feasible, the data will be synthesised using appropriate statistical techniques. Included articles will be reviewed for an ethics statement. The findings of the review will be disseminated in a related peer-reviewed journal and presented at conferences. They will also contribute to the work developed in the Real World Outcomes across the Alzheimer's disease spectrum for better care: multi-modal data access platform (ROADMAP).

    2016-07-01

    Full Text Available Introduction: Note taking while attending a PPT requires high activity of memory and writing process which ultimately leads to what is called “death by power point” referring to boredom and fatigue. To overcome this we planned to evaluate the impact of utilisation of uncompleted handouts given prior to PPT presentations. Methods: Final year MBBS students were divided in 2 batches, batch A and batch B. For a set of lectures one batch was provided with handouts before lecture while the other batch was given lectures only. Crossover was done to avoid bias, all the lectures being given by the same presenter. At the end of each lecture, a short questionnaire of 10 Multiple Choice Question (MCQ was provided to the students. Mean scores were calculated for lectures with handouts and without handouts. Results: For a set of lectures, when batch A was provided with handouts, the mean score was 28.2; for batch B to which no handouts were given the mean score was 23.4. Similarly, for batch B when provided with handouts the mean score was 29.1, for batch A which was not provided with handouts the mean score was 24. There was an average increase of 4.2 marks. Actual gain when handouts were provided was 1.2 marks per lecture. It was more for the batch comprising of repeater students as compared to the batch of fresher students. Increase in attendance was also noted. Conclusion: Providing uncompleted handouts before a didactic lecture definitely results in increase in knowledge gain; repeater students benefit more with uncompleted handouts.

    Purpose Maintaining productive employment for people with persistent pain conditions is challenging. This study aims to explore supports-work and non-work- used by employees to assist them in maintaining productive employment. Methods An exploratory, mixed-methods study comprising a questionnaire battery followed by semi-structured interviews to collect in-depth qualitative data was undertaken. The questionnaires measured descriptive variables used to select participants for interviews based on maximum heterogeneity sampling. Thirty-five semi-structured interviews were undertaken (14 males; 21 females). The interview schedule covered: employment situation, workplace challenges, workplace supports, coping strategies, motivations, future employment options and any other resources utilised. Inductive content analysis was undertaken using a grounded theory approach to systematically explore the data. Results Three key themes were identified: barriers to working productively, enablers to working productively, disclosing my condition at work. A key determinant of maintaining productive employment was a supportive employer. In addition, flexibility in the work organisation was also pivotal in maintaining sustainable, productive employment. An important issue emerged with regard to disclosure of one's condition to an employer. For some, this was a significant barrier to employment. Conclusions To ensure sustainable employment is attainable for those with persistent pain conditions, a good match is required between an employee and their work. Workplace accommodations may assist with improving job fit but this requires disclosure of a condition to an employer. Weighing up the risks and benefits of disclosure is difficult, and may be assisted by knowledge of available supports to assist with maintaining ongoing employment.

    Recent research has shown microbial ecosystems exist under glaciers and ice sheets. The sources of energy to support these ecosystems are still not fully understood, particularly beneath the Antarctic Ice Sheet, where direct access to the atmosphere and in-washed organic matter and oxidising agents does not occur. Hence, sub-ice sheet energy sources are restricted to those in subglacial environments, except for ice-margin environments. This study focuses on sediments from Subglacial Lake Whillans (SLW), the first subglacial lake to be directly and cleanly sampled. Sediment from three depths in a shallow core extracted from SLW were used to assess the possible energy contributions from mechanochemical reactions to this subglacial ecosystem. To do this, the samples were crushed under an anoxic atmosphere using a ball mill. The sediments were then transferred into serum bottles under anoxic conditions. They were wetted and the headspace gas was subsequently sampled and analysed during a 40 day incubation. Results show the release of substantial amounts of hydrogen, which could potentially serve as an abiotic source of energy to microbes, in particular, methanogenic archaea. Significant amounts of short chain hydrocarbons (including methane and ethylene), possibly from the reactivation of ancient organic carbon, were also observed. Crushed samples showed a significant concentration of hydrogen peroxide produced on contact with water, as well as significant amounts of Si radicals, showing comminution of these sediments unlocks the potential for a wide range of redox conditions and reactions to develop within glacially eroded sediment under ice. This in turn provides a previously overlooked source of nutrients and energy for microbes to utilise.

    Full Text Available Orientation: This  study  constituted  and  reported  on  the  outcomes  of  a  structured  career conversation  framework  based  on  Schein’s  eight  career  anchors  in  an  open  distance  and e-learning (ODeL university in South Africa. Research purpose: The purpose of the research was to report on the utilisation of a structured career conversation framework based on Schein’s career anchors model. Motivation for the study: The rationale for the study was the paucity of studies investigating career anchors in South Africa’s multicultural organisational context. Research design, approach and method: A quantitative approach was adopted in the study. The population consisted of 4200 employees at a university in South Africa. Statistical analysis was performed using one-way analysis of variance (ANOVA as well as a Scheffe post hoc test. Main  findings: The  findings  of  this  study  suggest  that  career  conversation  has  a  dynamic nature (i.e. it changes over a period of time. Consequently, career development interventions in the workplace need to approach the workforce holistically. Practical/managerial implications: The findings and results will assist managers, practitioners and  career  development  specialists  in  the  practical  implementation  of  the  career  anchor concept. Contribution/value-add: The career conversation framework based on Schein’s career anchors has expanded the existing theory to find the right balance between career conversations and career anchors to keep people motivated to perform optimally in an organisation.

    Introduction Dementia is the fastest growing major cause of disability globally with a mounting social and financial impact for patients and their families but also to health and social care systems. This review aims to systematically synthesise evidence on the utilisation of resources and costs incurred by patients and their caregivers and by health and social care services across the full spectrum of dementia, from its preceding preclinical stage to end of life. The main drivers of resources used and costs will also be identified. Methods and analysis A systematic literature review was conducted in MEDLINE, EMBASE, CDSR, CENTRAL, DARE, EconLit, CEA Registry, TRIP, NHS EED, SCI, RePEc and OpenGrey between January 2000 and beginning of May 2017. Two reviewers will independently assess each study for inclusion and disagreements will be resolved by a third reviewer. Data will be extracted using a predefined data extraction form following best practice. Study quality will be assessed with the Effective Public Health Practice Project quality assessment tool. The reporting of costing methodology will be assessed using the British Medical Journal checklist. A narrative synthesis of all studies will be presented for resources used and costs incurred, by level of disease severity when available. If feasible, the data will be synthesised using appropriate statistical techniques. Ethics and dissemination Included articles will be reviewed for an ethics statement. The findings of the review will be disseminated in a related peer-reviewed journal and presented at conferences. They will also contribute to the work developed in the Real World Outcomes across the Alzheimer’s disease spectrum for better care: multi-modal data access platform (ROADMAP).

    Swedish biomass production potential could be increased significantly if new production methods, such as optimised fertilisation, were to be used. Optimised fertilisation on 25% of Swedish forest land and the use of stem wood could almost double the biomass potential from forestry compared with no fertilisation, as both logging residues and large quantities of excess stem wood not needed for industrial purposes could be used for energy purposes. Together with energy crops and straw from agriculture, the total Swedish biomass potential would be about 230 TWh/yr or half the current Swedish energy supply if the demand for stem wood for building and industrial purposes were the same as today. The new production methods are assumed not to cause any significant negative impact on the local environment. The cost of utilising stem wood produced with optimised fertilisation for energy purposes has not been analysed and needs further investigation. Besides replacing fossil fuels and, thus, reducing current Swedish CO 2 emissions by about 65%, this amount of biomass is enough to produce electricity equivalent to 20% of current power production. Biomass-based electricity is produced preferably through co-generation using district heating systems in densely populated regions, and pulp industries in forest regions. Alcohols for transportation and stand-alone power production are preferably produced in less densely populated regions with excess biomass. A high intensity in biomass production would reduce biomass transportation demands. There are uncertainties regarding the future demand for stem wood for building and industrial purposes, the amount of arable land available for energy crop production and future yields. These factors will influence Swedish biomass potential and earlier estimates of the potential vary from 15 to 125 TWh/yr. (author)

    In this paper, three practical operation strategies (24Optimal, 24Prognostic, and 24Hsitrocial) are compared to the optimum profit feasible for a PHES facility with a 360 MW pump, 300 MW turbine, and a 2 GWh storage utilising price arbitrage on 13 electricity spot markets. The results indicate that almost all (∼97%) of the profits can be obtained by a PHES facility when it is optimised using the 24Optimal strategy developed, which optimises the energy storage based on the day-ahead electricity prices. However, to maximise profits with the 24Optimal strategy, the day-ahead electricity prices must be the actual prices which the PHES facility is charged or the PHES operator must have very accurate price predictions. Otherwise, the predicted profit could be significantly reduced and even become a loss. Finally, using the 24Optimal strategy, the PHES profit can surpass the annual investment repayments required. However, over the 5-year period investigated (2005-2009) the annual profit from the PHES facility varied by more than 50% on five out of six electricity markets considered. Considering the 40-year lifetime of PHES, even with low investment costs, a low interest rate, and a suitable electricity market, PHES is a risky investment without a more predictable profit. - Highlights: → Electricity generators typically operate on a market, including energy storage. → This paper assesses how energy storage can maximise its profits on a market. → Four operating strategies are assessed on 13 markets using a case study.→ One operating strategy achieves 97% of the profits feasible.→ However, the profit varies a lot depending on the market and capital costs.

    Tuberculosis (TB) remains one of the most deadly infections with approximately a quarter of cases not being identified and/or treated mainly due to a lack of resources. Rapid detection of TB or drug-resistant TB enables timely adequate treatment and is a cornerstone of effective TB management. We evaluated the analytical performance of a single-tube assay for multidrug-resistant TB (MDR-TB) on an experimental platform utilising RT-PCR and melting curve analysis that could potentially be operated as a point-of-care (PoC) test in resource-constrained settings with a high burden of TB. Firstly, we developed and evaluated the prototype MDR-TB assay using specimens extracted from well-characterised TB isolates with a variety of distinct rifampicin and isoniazid resistance conferring mutations and nontuberculous Mycobacteria (NTM) strains. Secondly, we validated the experimental platform using 98 clinical sputum samples from pulmonary TB patients collected in high MDR-TB settings. The sensitivity of the platform for TB detection in clinical specimens was 75% for smear-negative and 92.6% for smear-positive sputum samples. The sensitivity of detection for rifampicin and isoniazid resistance was 88.9 and 96.0% and specificity was 87.5 and 100%, respectively. Observed limitations in sensitivity and specificity could be resolved by adjusting the sample preparation methodology and melting curve recognition algorithm. Overall technology could be considered a promising PoC methodology especially in resource-constrained settings based on its combined accuracy, convenience, simplicity, speed, and cost characteristics.

    1. The effect of different levels of dietary iron on phytase activity and its subsequent effect on broiler performance were investigated in a 3 × 2 factorial arrangement. A total of 360 day-old Ross 308 male broiler chicks were distributed to 6 experimental diets, formulated with three levels of Fe (60, 80 and 100 mg/kg) and two levels of phytase (0 and 500 FTU/kg). 2. Phytase supplemented to mid-Fe diets increased feed consumption more than the non-supplemented diet at d 24. From hatch to d 35, Fe × phytase interaction significantly influenced the feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR). The high-Fe diet supplemented with phytase significantly reduced FI and BWG of broilers than those supplemented with low- or mid-Fe diets. The overall FCR was significantly better in birds fed on the mid-Fe diets with phytase supplementation. 3. A significant improvement in ileal digestibility of N, P, Mg and Fe was observed in birds feed diets containing 60 mg Fe/kg, with significant interaction between Fe and phytase. 4. Phytase improved the bone breaking strength when supplemented to low- or mid-Fe diets, compared to the non-supplemented diets. There was a significant Fe × phytase interaction effect. Tibia Fe content was higher in birds fed on phytase-free diets with high Fe but the reverse was the case when phytase was added and their interaction was significant. High dietary Fe significantly increased the accumulation of Fe in liver. 5. Phytase improved Ca-Mg-ATPase, Ca-ATPase and Mg-ATPase activities in jejunum when supplemented to the diet containing 80 mg Fe/kg. 6. This study indicates that high (100 mg/kg) dietary Fe inhibited phytase efficacy and subsequently reduced the overall performance and nutrient utilisation of broilers.

    Conclusion: In this study, overall utilisation of US in the diagnosis of EP was found to be low. In this population, patients presented late and critically ill, obviating the need for US in many cases. However, studies in Sub-Saharan Africa in populations of patients with similar rates of late presentations have shown a substantial increase in the diagnosis of unruptured EP with the routine use of US.

    The progression of dementia disease implies increasing needs for both informal and formal care and services but also risk of institutionalisation. To better adjust care and services in the phase preceding institutionalisation it is important to find out whether utilisation of formal and informal care and services is determined by increased needs and by who meets the needs. The aim was to compare persons with dementia (65+) with different levels of cognitive impairment, regarding utilisation of formal and informal care and service at home. The participants consisted of 177 persons with dementia ≥65 years old and at risk of nursing home admission, divided into groups according to their cognitive function. Structured interviews were conducted based on questionnaires about type and amount of formal and informal care utilised, as well as questions regarding cognitive impairment, dependency in activities of daily living (ADLs) and neuropsychiatric symptoms. To analyse the data, descriptive and comparative statistics were used. The findings revealed that the group with severe dementia used significantly more help with ADLs and supervision in terms of time (number of hours and days) provided by the informal caregiver, compared with the group with moderate dementia. Utilisation of formal care and services was highest in the group with the most severe cognitive impairments (Standardized Mini-Mental State Examination score of <9). The group with severe dementia were more dependent in ADLs and had more neuropsychiatric symptoms (hallucinations and motor disturbances). They were younger and more often cohabitated with the informal caregiver, compared with the group with moderate dementia. This study shows that in the phase preceding institutionalisation the ADL and supervision needs due to progression of dementia appear to tend to be met first and foremost by the informal caregivers. © 2017 Nordic College of Caring Science.

    Despite achieving some success, wealth-related disparities in the utilisation of maternal and child health services persist in the Philippines. The aim of this study is to decompose the principal factors driving the wealth-based utilisation gap. Using national representative data from the 2013 Philippines Demographic and Health Survey, we examine the extent overall differences in the utilisation of maternal health services can be explained by observable factors. We apply nonlinear Blinder-Oaxaca-type decomposition methods to quantify the effect of differences in measurable characteristics on the wealth-based coverage gap in facility-based delivery. The mean coverage of facility-based deliveries was respectively 41.1 % and 74.6 % for poor and non-poor households. Between 67 and 69 % of the wealth-based coverage gap was explained by differences in observed characteristics. After controlling for factors characterising the socioeconomic status of the household (i.e. the mothers' and her partners' education and occupation), the birth order of the child was the major factor contributing to the disparity. Mothers' religion and the subjective distance to the health facility were also noteworthy. This study has found moderate wealth-based disparities in the utilisation of institutional delivery in the Philippines. The results confirm the importance of recent efforts made by the Philippine government to implement equitable, pro-poor focused health programs in the most deprived geographic areas of the country. The importance of addressing the social determinants of health, particularly education, as well as developing and implementing effective strategies to encourage institutional delivery for higher order births, should be prioritised.

    The potential climate impact from the use of peat for energy production in Sweden was evaluated in terms of contribution to atmospheric radiative forcing. The calculations consider emissions from combustion and from the peatlands before, during and after harvesting. Four main groups of peatlands in use for peat harvesting were identified: 1. pristine peatlands; 2. drained peatlands used for agriculture; 3. drained peatlands used for forestry (low productive); 4. peatlands previously (historically) used for peat harvesting. The radiative forcing of different scenarios using the mentioned peatland types for energy peat production was calculated, using literature and empirical data related to peat harvesting, at these four types of mires. In the calculations the original land-use was set as reference scenario. The radiative forcing caused by using agricultural peatlands for energy peat production was much lower than for the corresponding use of pristine peatlands and old peat harvesting areas. The calculated value for the radiative forcing of current (20-year period of harvesting and combustion) peat utilisation for energy in a 100-year perspective ranges between 80-90% of the corresponding radiative forcing from using coal and 165-180% from using natural gas. The scenarios for different peatland types and the currently used peatlands show that there is a potential to reduce the radiative forcing caused by energy peat production and utilisation in Sweden by selecting peat harvesting area and after-treatment method. It was concluded that both the greenhouse gas balance of the peatland before harvesting and the after-treatment methods strongly impact the radiative forcing from energy peat utilisation. The radiative forcing from continuous utilisation of energy peat was also calculated a few scenarios. The results show a slower development than the shorter harvesting/combustion scenarios. Since new peat continuously is burnt it will take longer time before the benefit of

    The present study investigated nutritional programming in Atlantic salmon to improve utilisation of a vegetable-based diet. At first exogenous feeding, fry were fed either a marine-based diet (Diet Mstimulus, 80% fishmeal (FM)/4% fish oil (FO)) or a vegetable-based diet (Diet Vstimulus, 10% FM/0% FO) for 3 weeks. Subsequently, all fish were then fed under the same conditions with a commercial, marine-based, diet for 15 weeks and thereafter challenged with a second V diet (Diet Vchallenge, 10% FM/0% FO) for 6 weeks. Diploid and triploid siblings were run in parallel to examine ploidy effects. Growth performance, feed intake, nutrient utilisation and intestinal morphology were monitored. Fish initially given Diet Vstimulus (V-fish) showed 24 % higher growth rate and 23 % better feed efficiency compared with M-fish when later challenged with Diet Vchallenge. There was no difference in feed intake between nutritional histories, but increased nutrient retentions highlighted the improved utilisation of a V diet in V-fish. There were generally few significant effects of nutritional history or ploidy on enteritis scores in the distal intestine after the challenge phase as only V-triploids showed a significant increase (Pnutritional programming and the ability to respond better when challenged later in life may be attributed to physiological and/or metabolic changes induced by the stimulus. This novel study showed the potential of nutritional programming to improve the use of plant raw material ingredients in feeds for Atlantic salmon.

    2013-01-01

    A major cause of energy inefficiency is a result of the generation of waste heat and the lack of suitable technologies for cost-effective utilisation of low grade heat in particular. The market potential for surplus/waste heat from industrial processes in the UK is between 10 TWh and 40 TWh, representing a significant potential resource which has remained unexploited to date. This paper reviews selected technologies suitable for utilisation of waste heat energy, with specific focus on low grade heat, including: (i) chemical heat pumps, such as adsorption and absorption cycles for cooling and heating; (ii) thermodynamic cycles, such as the organic Rankine cycle (ORC), the supercritical Rankine cycle (SRC) and the trilateral cycle (TLC), to produce electricity, with further focus on expander and zeotropic mixtures, and (iii) thermal energy storage, including sensible and latent thermal energy storages and their corresponding media to improve the performance of low grade heat energy systems. - Highlights: ► The review of various thermal technologies for the utilisation of under exploited low grade heat. ► The analyses of the absorption and adsorption heat pumps possibly with performance enhancement additives. ► The analyses of thermal energy storage technologies (latent and sensible) for heat storage. ► The analyses of low temperature thermodynamic cycles to maximise power production.

    Siblings of children with mental health problems (MHPs) have been found to have higher rates of psychopathology and impaired psychosocial functioning compared to control children. It is not yet known how these siblings are managed within the clinical service context (e.g., are they assessed for mental health problems? Do they receive appropriate psychological treatment?). The following brief report describes a pilot study which aimed to explore (a) the rate of caregiver-identified MHPs in siblings and (b) the proportion of siblings receiving psychiatric or psychosocial treatment or support (i.e., treatment utilisation). Eighty-five caregivers of children receiving treatment at CAMHS were interviewed about the mental health and treatment utilisation of their siblings. The findings revealed a high rate of caregiver-identified MHPs in siblings (34.1%) and a high rate of treatment utilisation (85.7%). The findings suggest that, for the vast majority, when siblings of children with MHPs are identified by their caregivers as having MHPs, they are receiving some kind of support and treatment. Implications for mental health service costs are discussed and recommendations for future research are outlined.

    Full Text Available The aim of this study was to evaluate the performance, nutrient utilisation and energy metabolism of broiler chicks fed 8 different wheat samples, supplemented or not with xylanase. Seven-hundred sixty eight male broilers (1-day-old were distributed to 16 experimental treatments (6 replicates per treatment. The treatments were in a factorial arrangement with 8 different wheats and 2 levels of xylanase (0 or 16,000 BXU/kg. The predicted apparent metabolisable energy (AME of the wheat samples ranged from 13.0 to 13.9 MJ/kg and all diets were formulated to contain the same amount of wheat. Body weight gain (BWG and feed intake (FI were measured at 21 d, as was jejunal digesta viscosity, and feed conversion ratio (FCR calculated. On day 24, one representative bird per pen was selected to calculate whole body energetics. At 21 d, 3 chicks per replicate were randomly allocated to metabolism cages for energy and nutrient utilisation determinations, and were continued on the experimental diets until 24-d-old. No interactions were observed for any performance response variables, ileal nutrient utilisation or digesta viscosity. Xylanase improved BWG and reduced FCR and digesta viscosity (P < 0.05. Wheat influenced dry matter (DM utilisation and xylanase increased ileal digestible energy (P = 0.04. Xylanase also improved (P < 0.05 DM and nitrogen retention. Apparent metabolisable energy and AME corrected for nitrogen (AMEn were subject to an interaction whereby wheats 2 and 6, which returned the lowest AME and AMEn values, responded to xylanase supplementation and the remainder did not. Net energy for production and the efficiency of energy use for production were not influenced by xylanase, but were affected by wheat (P < 0.05. Despite the significant differences between wheats with regards to their nutrient utilisation and energy metabolism in birds, xylanase removed this variance and resulted in more homogeneous performance.

    The wide-ranging utilisation of Rapakivi Granite in St Petersburg is typified by the the famous Alexander Column, and 114 stone columns of St Isaac's Cathedralas well as the pedestal of the Nicholas I monument, and portals and basements of buildings of the Admiralty, General Staff, Senate and Synod. The stone is also frequently seen among pavement slabs and in parapets of embankments and bridges around the city. This list of examples where Rapakivi Granite has been used could be expanded further. All Rapakivi Granites used in the buildings of St.Petersburg were quarried from the so-called Vyborg massif. At present it has been found that the massif occupies an area of about 18 000 km2. In the past granite of the Vyborg massif was worked from several quarries in the vicinity of Fredrikshamn (Hamina) in Finland for use in St Peterburg. The best known granite quarries are at Piterlaks (Piuterlahti) and Gimmekyul (Hämeenkylä). Sometimes Rapakivi Granite form Finland differs in appearance from typical varieties. Thus columns of a classical portal in the house at N 7 in Pochtamtskaya Street are hewn from this greyish variety. Other examples are the plinth of the General Staff and Trade Store buildings. After the 1960s varieties from the Leningrad district, and Korosten (Ukraine) massifs were used in St Petersburg. Today it is possible to find examples of Rapakivi Granite from Finland in cities in the USA, South Africa, United Kingdom and Germany. It is a long used stone as demonstrated by its cultural heritage. It is also used as an ornamental or decorative stone in modern architecture.

    Full Text Available This article describes the concept and development of a knowledge-based advisory system for the optimum utilisation of South African wool for the benefit of present and potential investors and other interested parties. Wool is a natural animal fibre produced in varying quantities around the world. The wool fibre is far from homogenous; its type and quality, such as fineness and length, depending on the breed of sheep and the environmental conditions prevailing during its growth. Wool is used in a variety of end uses, ranging from fi ne worsted suiting, to hand knitting yarn, carpets, blankets and aircraft upholstery, its use depending largely on its fibre fineness and length. The wool industry is one of the oldest agricultural industries in South Africa, playing an important economic role as an earner of foreign exchange, and providing a living to many people. Wool is produced in many parts of South Africa under extensive, semi-extensive or intensive conditions, and is largely an export commodity. It is produced and traded in a sophisticated free market business environment into the international market place, where supply and demand forces determine price levels. More than 90% of locally produced wool is exported in an unprocessed or semi-processed form which detrimentally affects employment, foreign exchange and income-generating opportunities associated with value-addition prior to export. To reduce the amount of wool exported in unprocessed or semi-processed form, wool-processing enterprises need to be established to produce internationally marketable end products. Therefore, South Africa needs to attract investors into the wool sector, who will set up manufacturing mills in an economically sustainable manner. Potential and present investors in the South African (S.A. wool industry need easily accessible and up-to-date information on the production statistics, processing properties and end-use pplications of the wool they need for the

    difficult problem in power plant tests has been the lack of critical measurements; therefore, the current emphasis of the study is two-phase MDR. Real-time application and preliminary semi-dynamic trials have also started. A simulation model for system testing has been made with InTouch and SQL. In this simulator it is possible to develop and test various automatic gross-error elimination and data warehouse strategies. In the case study of Fortum and VTT Technical Research Centre of Finland - Flow rates in a peat power plant - the aim is to apply VTT's and Fortum's dynamical process simulation tool Apros to calculate flow rates, temperatures and pressures in peat drying process, which utilises the combustion gas of the power plant itself. This test case has been finalised and reported. The Apros tool was partially successful in answering the questions given by power plant operators. The biggest advantage of using Apros, compared to studying the minute-based process data from the plant itself, is that cause and effects are clearly distinguishable. It is relatively straightforward to calculate correlations and some more advanced measures between analysed process parameters, but it is difficult to reason out causes from all that data. The other important advantage is to study the plant in states which are encountered rarely or never in the typical use of the plant. Sometimes it might even be dangerous to run the plant in certain conditions, which are safely demonstrated by Apros

    their duty or the children are removed from their care. This does not in the least mean that the state has no responsibilities to children living with their parents. The state must still provide the framework in which parents can facilitate the realisation of their children's rights. The state can fulfil this obligation by taking reasonable legislative and other measures within its available resources to realise everyone's right of access to adequate housing progressively. Therefore, it is submitted that the measures taken to realise section 26 also indirectly ensures the realisation of children's right to basic shelter (section 28(1(c.It has been largely accepted by the courts and academics alike that all fundamental human rights are indivisible and interrelated. Clearly then, the state's obligations in terms of section 28(1(c cannot be properly interpreted without referring to the interpretation of those obligations conferred upon it by section 26(2 and the other socio-economic rights in the Constitution. Hence, section 28(1(c must be seen in the context of the Constitution as a whole. Put simply, the state must take reasonable legislative and other measures within its available resources to realise children's right to basic housing/shelter progressively.This article will focus on the utilisation of the right to shelter of the child to alleviate poverty. Essential to this discussion is an effective understanding of the right to basic shelter as entrenched by section 28 of the Constitution in conjunction with the right of access to adequate housing conferred on everyone by virtue of section 26. This will be achieved by studying the general working of such rights including their limitations and enforcement.

  1. The utilisation of municipal waste compost for the reclamation of anthropogenic soils: implications on C dynamics.

    samples show that even after 10 years, amended topsoils were significantly enriched in compost-derived organic matter, confirming that the utilisation of such organic inputs in land reclamation activities has the potential to enhance the C stocks of degraded areas. The addition of compost to the superficial layer also resulted in a significant input of soluble organic compounds subject to leaching along the soil profile. Sorption isotherms for compost-derived water-extractable organic matter onto mineral materials used for landfill covering suggest that sorptive preservation was primarily responsible for the increase in C content and the shift in the C isotopic signature to values similar to that of the applied compost, in the deeper soil horizons over the 10 year experimental period. This was also confirmed by the accumulation of lignin-derived phenolic compounds. Nevertheless, analysis for non-cellulosic carbohydrates in soils samples and their respective water-extractable fractions suggest that a proportion of compost-derived, labile organic matter fraction is leached through the soil profile and potentially lost from the soil system, particularly in the years immediately after compost application.

    This systematic review identifies, describes and appraises the literature describing the utilisation of helicopter emergency medical services (HEMS) in the early medical response to major incidents. Early prehospital phase of a major incident. Systematic literature review performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Web of Science, PsycINFO, Scopus, Cinahl, Bibsys Ask, Norart, Svemed and UpToDate were searched using phrases that combined HEMS and 'major incidents' to identify when and how HEMS was utilised. The identified studies were subjected to data extraction and appraisal. The database search identified 4948 articles. Based on the title and abstract, the full text of 96 articles was obtained; of these, 37 articles were included in the review, and an additional five were identified by searching the reference lists of the 37 articles. HEMS was used to transport medical and rescue personnel to the incident and to transport patients to the hospital, especially when the infrastructure was damaged. Insufficient air traffic control, weather conditions, inadequate landing sites and failing communication were described as challenging in some incidents. HEMS was used mainly for patient treatment and to transport patients, personnel and equipment in the early medical management of major incidents, but the optimal utilisation of this specialised resource remains unclear. This review identified operational areas with improvement potential. A lack of systematic indexing, heterogeneous data reporting and weak methodological design, complicated the identification and comparison of incidents, and more systematic reporting is needed.

    2014-01-01

    Background Evaluations are essential to judge the success of public health programmes. In Europe, the proportion of public health programmes that undergo evaluation remains unclear. The European Centre for Disease Prevention and Control sought to determine the frequency of evaluations amongst European national public health programmes by using national hand hygiene campaigns as an example of intervention. Methods A cohort of all national hand hygiene campaigns initiated between 2000 and 2012 was utilised for the analysis. The aim was to collect information about evaluations of hand hygiene campaigns and their frequency. The survey was sent to nominated contact points for healthcare-associated infection surveillance in European Union and European Economic Area Member States. Results Thirty-six hand hygiene campaigns in 20 countries were performed between 2000 and 2012. Of these, 50% had undergone an evaluation and 55% of those utilised the WHO hand hygiene intervention self-assessment tool. Evaluations utilised a variety of methodologies and indicators in assessing changes in hand hygiene behaviours pre and post intervention. Of the 50% of campaigns that were not evaluated, two thirds reported that both human and financial resource constraints posed significant barriers for the evaluation. Conclusion The study identified an upward trend in the number of hand hygiene campaigns implemented in Europe. It is likely that the availability of the internationally-accepted evaluation methodology developed by the WHO contributed to the evaluation of more hand hygiene campaigns in Europe. Despite this rise, hand hygiene campaigns appear to be under-evaluated. The development of simple, programme-specific, standardised guidelines, evaluation indicators and other evidence-based public health materials could help promote evaluations across all areas of public health.

    Full Text Available Out-of-pocket (OOP payments have severe consequences for health care access and utilisation and are especially catastrophic for the poor. Although women comprise the majority of the poor in Nigeria and globally, the implications of OOP payments for health care access from a gender perspective have received little attention. This study seeks to fill this gap by using a combination of quantitative and qualitative analysis to investigate the gendered impact of OOPs on healthcare utilisation in south-eastern Nigeria. 411 households were surveyed and six single-sex Focus Group Discussions conducted. This study confirmed the socioeconomic and demographic vulnerability of female-headed households (FHHs, which contributed to gender-based inter-household differences in healthcare access, cost burden, choices of healthcare providers, methods of funding healthcare and coping strategies. FHHs had higher cost burdens from seeking care and untreated morbidity than male-headed households (MHHs with affordability as a reason for not seeking care. There is also a high utilisation of patent medicine vendors (PMVs by both households (PMVs are drug vendors that are unregulated, likely to offer very low-quality treatment and do not have trained personnel. OOP payment was predominantly the means of healthcare payment for both households, and households spoke of the difficulties associated with repaying health-related debt with implications for the medical poverty trap. It is recommended that the removal of user fees, introduction of prepayment schemes, and regulating PMVs be considered to improve access and provide protection against debt for FHHs and MHHs. The vulnerability of widows is of special concern and efforts to improve their healthcare access and broader efforts to empower should be encouraged for them and other poor households.

    The objective of this study was to investigate possibilities to extract and utilise biogas from municipal solid waste in Lusaka, considering environmental, financial, technological and social aspects. The outcome provided three recommendations: 1 - a new landfill with biocells. The only legal tipping site in Lusaka has been condemned and there are plans for the construction of a new landfill. We recommend that the new site should be a sanitary landfill with full gas and leachate management. Thus, the costs for extracting biogas would be included in the investments for the landfill. It would be advisable to start with a simple end-use application during a running-in period when the technique and organisation is tested. Utilising the gas for internal heating or in a nearby industry will probably be the easiest and cheapest choice. 2 - a pilot project in a high-density area for co-dispersal of latrine and putrescibles. The sanitary conditions in high-density areas, where pit-latrines are the principal sanitary method, are insufficient. It is of great importance to master the situation in order to avoid further epidemics and water pollution. Compared to other solutions we consider a fermentation digester to be the best alternative. The main purpose for this pilot plant would, at least in the initial stage, be to investigate whether this method is a feasible solution for the problems with pit latrines. The aim of the end-use application could then merely be to demonstrate and inform the public about biogas. 3 - further investigations regarding the possibilities to extract and utilise biogas in industries and from manure, The estimated biogas potential from industries and manure and droppings from livestock and chickens is much bigger than from municipal solid waste and should be exploited. The end-use applications would probably be for internal use (heat and/or electricity). This was not investigated any further in our study.

    Full Text Available Abstract Background Russian society has faced dramatic changes in terms of social stratification since the collapse of the Soviet Union. During this time, extensive reforms have taken place in the organisation of health services, including the development of the private sector. Previous studies in Russia have shown a wide gap in mortality between socioeconomic groups. There are just a few studies on health service utilisation in post-Soviet Russia and data on inequality of health service use are limited. The aim of the present study was to analyse health (self-rated health and self-reported chronic diseases and health care utilisation patterns by socioeconomic status (SES among reproductive age women in St. Petersburg. Methods The questionnaire survey was conducted in 2004 (n = 1147, with a response rate of 67%. Education and income were used as dimensions of SES. The association between SES and health and use of health services was assessed by logistic regression, adjusting for age. Results As expected low SES was associated with poor self-rated health (education: OR = 1.48; personal income: OR = 1.42: family income: OR = 2.31. University education was associated with use of a wider range of outpatient medical services and increased use of the following examinations: Pap smear (age-adjusted OR = 2.06, gynaecological examinations (age-adjusted OR = 1.62 and mammography among older (more than 40 years women (age-adjusted OR = 1.98. Personal income had similar correlations, but family income was related only to the use of mammography among older women. Conclusions Our study suggests a considerable inequality in health and utilisation of preventive health service among reproductive age women. Therefore, further studies are needed to identify barriers to health promotion resources.

    Full Text Available Geographic accessibility to health facilities represents a fundamental barrier to utilisation of maternal and newborn health (MNH services, driving historically hidden spatial pockets of localized inequalities. Here, we examine utilisation of MNH care as an emergent property of accessibility, highlighting high-resolution spatial heterogeneity and sub-national inequalities in receiving care before, during, and after delivery throughout five East African countries.We calculated a geographic inaccessibility score to the nearest health facility at 300 x 300 m using a dataset of 9,314 facilities throughout Burundi, Kenya, Rwanda, Tanzania and Uganda. Using Demographic and Health Surveys data, we utilised hierarchical mixed effects logistic regression to examine the odds of: 1 skilled birth attendance, 2 receiving 4+ antenatal care visits at time of delivery, and 3 receiving a postnatal health check-up within 48 hours of delivery. We applied model results onto the accessibility surface to visualise the probabilities of obtaining MNH care at both high-resolution and sub-national levels after adjusting for live births in 2015.Across all outcomes, decreasing wealth and education levels were associated with lower odds of obtaining MNH care. Increasing geographic inaccessibility scores were associated with the strongest effect in lowering odds of obtaining care observed across outcomes, with the widest disparities observed among skilled birth attendance. Specifically, for each increase in the inaccessibility score to the nearest health facility, the odds of having skilled birth attendance at delivery was reduced by over 75% (0.24; CI: 0.19-0.3, while the odds of receiving antenatal care decreased by nearly 25% (0.74; CI: 0.61-0.89 and 40% for obtaining postnatal care (0.58; CI: 0.45-0.75.Overall, these results suggest decreasing accessibility to the nearest health facility significantly deterred utilisation of all maternal health care services.

  14. Differences in home-based palliative care service utilisation of people with cancer and non-cancer conditions.

    Kralik, Debbie; Anderson, Barbara

    2008-11-01

    To identify home-based palliative care service utilisation by people with cancer and non-cancer conditions. Palliative care knowledge and skill have been derived from working with people with cancer. People with chronic conditions are now referred for home-based palliative care; however, there has been few studies published that have explored the impact of service utilisation by people with end-stage chronic conditions. The Australia-modified Karnofsky Performance Status (AKPS) scale was calculated for each person upon referral for home-based palliative care services to determine the functional capacity of the individual at the point of referral. Clients were divided into those with cancer diagnosis and those with non-cancer diagnosis. Service utilisation of the individual client was determined until separation from the palliative care service. The study was undertaken in 2007. The majority of people with cancer (63%) and non-cancer (71%) were assessed as having an AKPS score between 50-60. Thirty-one cancer clients (18·7%) and three non-cancer clients (7·1%) had an AKPS score between 70-90. This suggests that people with cancer are referred to palliative care services earlier than people with non-cancer conditions. People with non-cancer conditions were substantially higher users of home-based palliative care services over a longer period of time. Home-based palliative care service utilisation was higher for people with non-cancer conditions. Cost analysis research is recommended to delineate the actual costs of home-based palliative care service provision between people with cancer and non-cancer conditions. There is growing awareness of the need for palliative care services for people with non-cancer conditions. However, these services are provided for longer periods of time for this client group. Implications for practice are that the palliative care needs of people with non-cancer conditions may not be met within current palliative care service provision

    Full Text Available Background: Electronic libraries are the recent development in the ever-changing technological world today. Students nowadays have the ability to carry the library wherever they are, their Internet-enabled devices being the only requirement. Most universities worldwide have subscribed to various online databases and other e-resources as a way of availing resources to their students. To their credit, most institutions of higher learning in developing countries have not been left out in this stampede.   Objectives: The study aimed at investigating the adoption and utilisation of e-resources by students at a university in a developing country.   Method: The Technology Acceptance Model (TAM model was used to conceptualise the study. A survey questionnaire was designed and distributed through social media platforms such as Facebook and WhatsApp. Quantitative data were analysed using the Statistical Package for the Social Sciences (SPSS. The Chi-squared test was used to test for casual relationships within the developed model. A thematic approach was used to analyse qualitative data. Results: Despite the fact that many Zimbabwean academic institutions have made the facility of e-libraries top agenda in their strategic plans, the adoption rate among students is still very limited. This can be attributed to a myriad of facts, inter alia, poor marketing strategies, lack of resources among the students and exorbitant data charges by Internet Service Providers (ISPs.   Conclusion: This study has provided some basic insights in utilisation of e-resources in universities of developing countries. Despite the younger generation being described as digital natives, it is, quite evident that their uptake of technological innovations especially in education is quite poor. This research will assist both researchers and management of institutions of higher learning to provide and design amicable solutions to the problem of poor utilisation of e-resources as

    Calcium and phosphorus are essential minerals, closely linked in digestive processes and metabolism. With widespread use of low P diets containing exogenous phytase, the optimal dietary Ca level was verified. The 40-day study evaluated the effects of Ca level (4, 7 and 10 g/kg diet) and Ca source (Ca from CaCO 3 and from Lithothamnium calcareum) on mineral utilisation in 72 piglets (7.9 ± 1.0 kg BW) fed an exogenous phytase containing diet with 2.9 g digestible P/kg. Measured parameters were growth performance, stomach mineral solubility, bone breaking strength and urinary, serum and bone mineral concentration. The apparent total tract digestibility of minerals was also assessed in the two diets with 7 g Ca/kg, using 12 additional pigs. Regardless of Ca source, increasing dietary Ca impaired feed conversion ratio, increased urinary pH, increased serum and urinary Ca, decreased serum and urinary P, decreased serum Mg and increased urinary Mg, increased serum AP activity, decreased bone Mg increased bone Zn. Bone breaking strength was improved with 7 compared to 4 g Ca/kg. Compared to CaCO 3 , Ca from Lithothamnium calcareum increased serum Mg and with, 10 g Ca/kg, it limited body weight gain. The dose response of Ca in a diet with 2.9 g digestible P/kg and including exogenous phytase indicated that: (i) a low dietary Ca was beneficial for piglet growth, but was limiting the metabolic use of P; (ii) a high dietary Ca level impaired P utilisation; (iii) the optimal P utilisation and bone breaking strength was obtained with a dietary Ca-to-digestible P ratio of 2.1 to 2.4:1; (iv). Increasing dietary Ca reduced Mg utilisation, but not Zn status, when fed at adequate level. Finally, Ca from Lithothamnium calcareum had similar effects on Ca and P metabolism as CaCO 3 , but impaired growth when fed at the highest inclusion level.

    Introduction In order to alleviate the problem of “Kan Bing Nan, Kan Bing Gui” (medical treatment is difficult to access and expensive) and improve the equity of health service utilisation for urban residents in China, the Urban Employee Basic Medical Insurance scheme (UEBMI) and Urban Resident Basic Medical Insurance scheme (URBMI) were established in 1999 and 2007, respectively. This study aims to analyse the effects of UEBMI and URBMI on the equity of outpatient and inpatient utilisation in Shaanxi Province, China. Methods Using the data from the fourth National Health Services Survey in Shaanxi Province, the method of Propensity Score Matching was employed to generate comparable samples between the insured and uninsured residents, through a one-to-one match algorithm. Next, based on the matched data, the method of decomposition of the concentration index was employed to compare the horizontal inequity indexes of health service utilisation between the UEBMI/URBMI insured and the matched uninsured residents. Results For the UEBMI insured and matched uninsured residents, the horizontal inequity indexes of outpatient visits are 0.1256 and -0.0511 respectively, and the horizontal inequity indexes of inpatient visits are 0.1222 and 0.2746 respectively. Meanwhile, the horizontal inequity indexes of outpatient visits are -0.1593 and 0.0967 for the URBMI insured and matched uninsured residents, and the horizontal inequity indexes of inpatient visits are 0.1931 and 0.3199 respectively. Conclusions The implementation of UEBMI increased the pro-rich inequity of outpatient utilisation (rich people utilise outpatient facilities more than the poor people) and the implementation of URBMI increased the pro-poor inequity of outpatient utilisation. Both of these two health insurance schemes reduced the pro-rich inequity of inpatient utilisation. PMID:24606592

    Cancer anorexia-cachexia syndrome (CACS) negatively impacts patients' quality of life (QoL) and increases the burden on healthcare resources. To review published CACS data regarding health-related QOL (HRQoL) and its economic impact on the healthcare system. Searches were conducted in MEDLINE, EMBASE, DARE, and NHS EED databases. A total of 458 HRQoL and 189 healthcare resources utilisation abstracts were screened, and 42 and 2 full-text articles were included, respectively. The EORTC QLQ-C30 and FAACT instruments were most favoured for assessing HRQOL but none of the current tools cover all domains affected by CACS. Economic estimates for managing CACS are scarce, with studies lacking a breakdown of healthcare resource utilisation items. HRQoL instruments that can better assess and incorporate all the domains affected by CACS are required. Rigorous assessment of costs and benefits of treatment are needed to understand the magnitude of the impact of CACS. Copyright © 2016. Published by Elsevier Ireland Ltd.

    One of the tenets of general practice is that continuity of care has a beneficial effect on patient care. However, little is known about how continuity can have an impact on the diagnostic reasoning of GPs. To explore GPs' diagnostic strategies by examining GPs' reflections on their patients' individual thresholds for seeking medical attention, how they arrive at their estimations, and which conclusions they draw. Qualitative study with 12 GPs in urban and rural practices in Germany. After each patient consultation GPs were asked to reflect on their diagnostic reasoning for that particular case. Qualitative and quantitative analyses of consultations and interview content were undertaken. A total of 295 primary care consultations were recorded, 134 of which contained at least one diagnostic episode. When elaborating on known patients, GPs frequently commented on how 'early' or 'late' in an illness progression a patient tended to consult. The probability of serious disease was accordingly regarded as high or low. This influenced GPs' behaviour regarding further investigations or referrals, as well as reassurance and watchful waiting. GPs' explanations for a patient's utilisation threshold comprised medical history, the patient's characteristics, family background, the media, and external circumstances. The concept of an individual threshold for the utilisation of primary care would explain how GPs use their knowledge of individual patients and their previous help-seeking behaviour for their diagnostic decision making. Whether the assumption behind this concept is valid, and whether its use improves diagnostic accuracy, remains to be investigated. © British Journal of General Practice 2017.

    2013-09-01

    Psychologists have utilised a range of social cognition models to understand variation in physical health and illness-related behaviours. The most widely studied model of illness perceptions has been the Self-Regulation Model (SRM, Leventhal, Nerenz, & Steele, 1984). The illness perceptions questionnaire (IPQ) and its revised version (IPQ-R) have been utilised to explore illness beliefs in physical health. This review examined 13 quantitative studies, which used the IPQ and IPQ-R in mental health in their exploration of illness perceptions in psychosis, bipolar disorder, eating disorders, depression and adolescents experiencing mood disorders. Across these studies the SRM illness dimensions were largely supported. Mental illnesses were commonly viewed as cyclical and chronic, with serious negative consequences. Perceptions regarding chronicity, controllability and negative consequences were associated with coping and help seeking, while engagement with services and help seeking were also related to illness coherence beliefs. Treatment adherence was linked to beliefs that treatment could control one's illness. Whilst a major limitation of the reviewed studies was the use of cross-sectional designs, overall the applicability of the SRM to mental health was supported. The IPQ and IPQ-R were shown to be valuable measures of illness perceptions in mental health, offering implications for clinical practice.

    This paper investigates the ability to develop synthetic scenes in an image generation tool, E-on Vue, and a gaming engine, Unity 3D, which can be used to generate synthetic imagery of target objects across a variety of conditions in land environments. Developments within these tools and gaming engines have allowed the computer gaming industry to dramatically enhance the realism of the games they develop; however they utilise short cuts to ensure that the games run smoothly in real-time to create an immersive effect. Whilst these short cuts may have an impact upon the realism of the synthetic imagery, they do promise a much more time efficient method of developing imagery of different environmental conditions and to investigate the dynamic aspect of military operations that is currently not evaluated in signature analysis. The results presented investigate how some of the common image metrics used in target acquisition modelling, namely the Δμ1, Δμ2, Δμ3, RSS, and Doyle metrics, perform on the synthetic scenes generated by E-on Vue and Unity 3D compared to real imagery of similar scenes. An exploration of the time required to develop the various aspects of the scene to enhance its realism are included, along with an overview of the difficulties associated with trying to recreate specific locations as a virtual scene. This work is an important start towards utilising virtual worlds for visible signature evaluation, and evaluating how equivalent synthetic imagery is to real photographs.

    Steven Brams's [(1994). Theory of moves. Cambridge University Press] Theory of Moves (TOM) is an alternative to traditional game theoretic treatment of real-life interactions, in which players choose strategies based on analysis of future moves and counter-moves that arise if game play commences at a specified start state and either player can choose to move first. In repeated play, players using TOM rationality arrive at nonmyopic equilibria. One advantage of TOM is its ability to model scenarios in which power asymmetries exist between players. In particular, threat power, i.e. the ability of one player to threaten and sustain immediate, globally disadvantageous outcomes to force a desirable result long term, can be utilised to induce Pareto optimal states in games such as Prisoner's Dilemma which result in Pareto-dominated outcomes using traditional methods. Unfortunately, prior work on TOM is limited by an assumption of complete information. This paper presents a mechanism that can be used by a player to utilise threat power when playing a strict, ordinal 2×2 game under incomplete information. We also analyse the benefits of threat power and support in this analysis with empirical evidence.

    This PhD thesis was written during my employment at the Research Unit of General Practice in Odense, University of Southern Denmark. It comprises an overview and three papers, all published or submitted for publication in international peer-reviewed scientific journals.   Non-infectious dyspnoea, chronic cough and wheezing are common symptoms in the population. Patients often present with these symptoms in general practice and have a high probability of having obstructive lung diseases. However, there is an indication that the majority of these patients are treated empirically with pharmacotherapy targeting obstructive lung disease and only few have additional tests conducted, although the predictive value of respiratory symptoms for diagnosing obstructive lung disease has proven to be low. Spirometry is recommended as the gold standard for confirming obstructive lung disease, and testing can also rule out airway obstruction in patients with respiratory symptoms caused by other illnesses, such as heart failure or lung cancer. Initiating medication for obstructive lung disease without spirometry entails the risk of these patients experiencing unnecessary delay in the diagnostic process and being exposed to unnecessary economic costs and medication risks. The literature has indicated that many users of medication targeting obstructive lung medication have not had spirometry performed and do not actually have obstructive lung disease. This potential quality gap needs to be assessed. Also, in order to target interventions enhancing earlier spirometry utilisation among patients initiating medication targeting obstructive lung disease, improved knowledge on patient and practice factors associated with spirometry testing is needed.   Among first time users of obstructive lung medication we aimed: - To assess to what extent spirometry was performed within the first year of medication use (Study I) - To assess if patient characteristics like socioeconomic and demographic

    Full Text Available Abstract Background Efforts to reduce neonatal mortality are essential if the Millennium Development Goal (MDG 4 is to be met. The impact of spatial dimensions of neonatal survival has not been thoroughly investigated even though access to good quality delivery care is considered to be one of the main priorities when trying to reduce neonatal mortality. This study examined the association between distance from the mother's home to the closest health facility and neonatal mortality, and investigated the influence of distance on patterns of perinatal health care utilisation. Methods A surveillance system of live births and neonatal deaths was set up in eight districts of Quang Ninh province, Vietnam, from July 2008 to December 2009. Case referent design including all neonatal deaths and randomly selected newborn referents from the same population. Interviews were performed with mothers of all subjects and GIS coordinates for mothers' homes and all health facilities in the study area were obtained. Straight-line distances were calculated using ArcGIS software. Results A total of 197 neonatal deaths and 11 708 births were registered and 686 referents selected. Health care utilisation prior to and at delivery varied with distance to the health facility. Mothers living farthest away (4th and 5th quintile, ≥1257 meters from a health facility had an increased risk of neonatal mortality (OR 1.96, 95% CI 1.40 - 2.75, adjusted for maternal age at delivery and marital status. When stratified for socio-economic factors there was an increased risk for neonatal mortality for mothers with low education and from poor households who lived farther away from a health facility. Mothers who delivered at home had more than twice as long to a health facility compared to mothers who delivered at a health care facility. There was no difference in age at death when comparing neonates born at home or health facility deliveries (p = 0.56. Conclusion Distance to the

    The subject of the thesis was to analyze by an engineering approach the global CO{sub 2} balance and CO{sub 2} utilisation. The aim was to apply methods and knowledge used in engineering sciences to describe the global CO{sub 2} balance and the role of CO{sub 2} in anthropogenic utilisation applications. Moreover barriers restricting commercialisation of new applications are discussed. These subjects were studied by literature reviews and calculations based on thermodynamics models. Engineering methods have shown to be applicable to describe the global balance of CO{sub 2} and to define by a numerical way the Earth's system carrying capacity. Direct and indirect actions, which mitigate the overload situation, were derived from the results. To screen out the attractive CO{sub 2} properties in utilisation applications a mapping analysis was carried out. Properties, which enhance mass and heat transfer, are one of the most meaningful characteristics from the chemical engineering point of view. Attractive properties are often achieved at the supercritical state. Engineering thermodynamic methods were used in fluid phase determination of the case studies. Even simple methods are sufficient to advice experimental research work. The thermodynamic knowledge is the basement in creation of industrial scale chemical processes. If detailed information on system properties is needed, a model development due to the special requirements of high pressure systems and CO{sub 2} features is required. This knowledge covers property information from all the components involved in chemical reactions. In addition to engineering knowledge successful technology transfer requires positive social structure as well. Finally, if the humankind is willing to mimic Nature and use light of the Sun as an energy source in engineering systems, development of thermodynamic methods is required also in this area.

    An estimated 10,000 Burmese migrants are currently living in London. No studies have been conducted on their access to health services. Furthermore, most studies on migrants in the United Kingdom (UK) have been conducted at the point of service provision, carrying the risk of selection bias. Our cross-sectional study explored access to and utilisation of General Practice (GP) services by Burmese migrants residing in London. We used a mixed-method approach: a quantitative survey using self-administered questionnaires was complemented by qualitative in-depth interviews for developing the questionnaire and triangulating the findings of the survey. Overall, 137 questionnaires were received (a response rate of 57%) and 11 in-depth interviews conducted. The main outcome variables of the study included GP registration, barriers towards registration, GP consultations, barriers towards consultations, and knowledge on entitlements to health care. Quantitative data were analysed using descriptive statistics, association tests, and a multivariate analysis using logistic regression. The qualitative information was analysed using content analysis. The respondents were young, of roughly equal gender (51.5% female), well educated, and had a fair level of knowledge on health services in the UK. Although the GP registration rate was relatively high (80%, 109 out of 136), GP service utilisation during the last episode of illness, at 56.8% (54 out of 95), was low. The statistical analysis showed that age being younger than 35 years, lacking prior overseas experience, having an unstable immigration status, having a shorter duration of stay, and resorting to self-medication were the main barriers hindering Burmese migrants from accessing primary health care services. These findings were corroborated by the in-depth interviews. Our study found that having formal access to primary health care was not sufficient to ensure GP registration and health care utilisation.

    Inequities in accessibility to, and utilisation of maternal healthcare services impede progress towards attainment of the maternal health-related Millennium Development Goals. The objective of this study is to examine the extent to which maternal health services are utilised in Ghana, and whether inequities in accessibility to and utilization of services have been eliminated following the implementation of a user-fee exemption policy, that aims to reduce financial barriers to access, reduce inequities in access, and improve access to and use of birthing services. We analyzed data from the 2007 Ghana Maternal Health Survey for inequities in access to and utilization of maternal health services. In measuring the inequities, frequency tables and cross-tabulations were used to compare rates of service utilization by region, residence and selected socio-demographic variables. Findings show marginal increases in accessibility to and utilisation of skilled antenatal, delivery and postnatal care services following the policy implementation (2003-2007). However, large gradients of inequities exist between geographic regions, urban and rural areas, and different socio-demographic, religious and ethnic groupings. More urban women (40%) than rural, 53% more women in the highest wealth quintile than women in the lowest, 38% more women in the best performing region (Central Region) than the worst (Upper East Region), and 48% more women with at least secondary education than those with no formal education, accessed and used all components of skilled maternal health services in the five years preceding the survey. Our findings raise questions about the potential equity and distributional benefits of Ghana's user-fee exemption policy, and the role of non-financial barriers or considerations. Exempting user-fees for maternal health services is a promising policy option for improving access to maternal health care, but might be insufficient on its own to secure equitable access to

    Full Text Available Abstract Background Support groups have proved to be effective in reducing the burden on family caregivers of dementia patients. Nevertheless, little is known about the factors that influence utilisation or quality expectations of family caregivers. These questions are addressed in the following paper. Methods The cross-sectional study was carried out as an anonymous written survey of family caregivers of dementia patients in Germany. Qualitative and quantitative data from 404 caregivers were analysed using content analysis and binary logistic regression analysis. Results The only significant predictor for utilisation is assessing how helpful support groups are for the individual care situation. Family caregivers all agree that psycho-educative orientation is a priority requirement. Conclusions In order to increase the rate of utilisation, family caregivers must be convinced of the relevant advantages of using support groups. Support groups which offer an exchange of experiences, open discussion, information and advice meet the requirements of family caregivers.

    To investigate hepatocellular carcinoma screening utilisation and factors associated with utilisation among patients prescribed hepatitis B virus anti-viral therapy and at risk of hepatocellular carcinoma. The incidence of hepatocellular carcinoma has increased in Australia over the past three decades with chronic hepatitis B virus infection a major contributor. hepatocellular carcinoma surveillance programs aim to detect cancers early enabling curative treatment options, longer survival and longer times to recurrence. Multi-site cross-sectional survey. An online study questionnaire was administered to eligible participants attending three Sydney tertiary hospitals. Data were grouped into six mutually exclusive hepatocellular carcinoma risk factor categories as per American Association for the Study of Liver Diseases guidelines. All analyses were undertaken in STATA. Logistic regression was used to assess the associations between covariates and screening utilisation. Multivariate models described were assessed using the Hosmer-Lemeshow goodness of fit. Of the 177 participants, 137 (77.4%) self-reported that US had been performed in the last six months. Awareness that screening should be performed and knowing the correct frequency of US screening were independently associated with screening utilisation. Participants who knew that screening should be undertaken were three times more likely to have had pretreatment education or were prescribed hepatitis B virus anti-viral treatment for >4 years. Participants reporting a family history of hepatocellular carcinoma were less likely to know that screening should be undertaken every 6 months. While utilisation of hepatocellular carcinoma surveillance programs was higher in this study than in previous reports, strategies to further improve surveillance remain necessary. Findings from this research form the basis for proposing strategies to improve utilisation of hepatocellular carcinoma screening, inform hepatitis B virus

    There are few Australian data that examine the association between total knee joint replacement (TKR) utilisation and socioeconomic status (SES). This study examined TKR surgeries with a diagnosis of osteoarthritis (OA) performed for residents of Barwon Statistical Division (BSD) for 2006-2007. Cross-sectional. BSD, South-eastern Victoria, Australia All patients who underwent a TKR for OA, 2006-2007, and whose residential postcode was identified as within the BSD of Australia, and for whom SES data were available, were eligible for inclusion. Primary TKR data ascertained from the Australian Orthopaedic Association National Joint Replacement Registry. Residential addresses were matched with the Australian Bureau of Statistics census data, and the Index of Relative Socioeconomic Disadvantage was used to determine SES, categorised into quintiles whereby quintile 1 indicated the most disadvantaged and quintile 5 the least disadvantaged. Age-specific and sex-specific rates of TKR utilisation per 1000 person-years were reported for 10-year age bands. Females accounted for 62.7% of the 691 primary TKR surgeries performed during 2006-2007. The greatest utilisation rates of TKR in males was 7.6 observed in those aged >79 years, and in 10.2 in females observed in those aged 70-79 years. An increase in TKR was observed for males in SES quintile four compared to quintile 1 in which the lowest utilisation which was observed (p=0.04). No differences were observed in females across SES quintiles. Further investigation is warranted on a larger scale to examine the role that SES may play in TKR utilisation, and to determine whether any social disparities in TKR utilisation reflect health system biases or geographic differences.

    The aim of the study was to ascertain the extent to which temperature influences the utilisation of main carbon sources (reducing substances determined before and after hydrolysis, glycerol and organic acids) by a mixed culture of thermo- and mesophilic bacteria of the genus Bacillus in the course of aerobic batch biodegradation of potato stillage, a high-strength distillery effluent (COD=51.88 g O(2)/l). The experiments were performed at 20, 30, 35, 40, 45, 50, 55, 60 and 63 degrees C, at pH 7, in a 5l working volume stirred-tank bioreactor (Biostat B, B. Braun Biotech International) with a stirrer speed of 550 rpm and aeration at 1.6 vvm. Particular consideration was given to the following issues: (1) the sequence in which the main carbon sources in the stillage were assimilated and (2) the extent of their assimilation achieved under these conditions.

    During prehistory fire-setting was the most appropriate technique for exploiting ore deposits. Charcoal fragments found in the course of archaeological excavations in a small mine called Mauk E in the area of Schwaz/Brixlegg (Tyrol, Austria) are argued to be evidence for the use of this technology. Dendrochronological analyses of the charcoal samples yielded calendar dates for the mining activities showing that the exploitation of the Mauk E mine lasted approximately one decade in the late 8th century BC. Dendrological studies show that the miners utilised stem wood of spruce and fir from forests with high stand density for fire-setting and that the exploitation of the Mauk E mine had only a limited impact on the local forests.

    From long-term real-time radon and radon progeny measurements taken in a relatively large retail store, cyclical patterns were evident, which were found to relate to the overriding influence of the timed air-conditioning system. Concentration of radon, radon progeny and the variability of F factor were found to depend significantly on the intermittent operation of this ventilation-air-conditioning system. After pressure equalisation remedial measures proved ineffective, the air-movement system was utilised to reduce the levels of radon and radon progeny to well within established norms applicable during working hours. It is demonstrated that the average levels for radon and radon progeny are reduced in absolute terms. This amounted to less than 12% of the general level, during designated work periods. Where air movement systems are already installed, as well as other circumstances, their regulation provides an economical solution to meeting legal and other standards for radon in the workplace.

    Full Text Available In this research the 5D-framework of Appreciative Inquiry is used to investigate the possibility of applying the attributes and artistic strategies of the pop singer Neil Diamond for the improvement of classroom practices of educationalists. During the attendance of the performances of Diamond in 2011 in South Africa the writers and five other educationalists have identified five broad qualities and practices of Diamond. These may have application value in a school or university classroom: passionate enthusiasm, purposeful dedication, communication and interaction with the audience, refusing to conform/creating variation as well as good planning. This is the first time that the 5D-cycle has been used to study the possible utilisation of a live performance of a popular artist to facilitate the professional development of educationalists.

  2. Assessment of the economic effects of financial incentives benefitting certain plants for renewable energy utilisation in Germany. Final report

    1993-01-01

    On account of their low sales figures, technologies for renewable energy utilisation are still rather expensive. A more decided support for their introduction to the market could boost the development in this field. The offer submitted by Fichtner Development Engineering on 21.04.1992 served as a basis for the commission by the Federal Minister for Economic Affairs. It comprised the following individual tasks; drawing up of a list of plants to be promoted; elaboration, assessment, and selection of suitable promotion mechanisms; elaboration of cause-and-effect relationships for estimating stimulus strength; principal executive questions; increase in number of plants sold and cost of promotion. The present report deals with these points. (orig./UA) [de

    This case-control study describes the health situation, internal and external resources, and utilisation of healthcare facilities by a marginalised population consisting of homeless people in Vienna, Austria, compared with a non-homeless control population. Among the homeless group, participants lived in halfway houses (70%) or permanent housing (30%) in Vienna. Personal interviews were conducted in July 2010 with 66 homeless individuals, and their data were compared with data from non-homeless subjects from the Austrian Health Interview Survey using conditional logistic regression. Compared with the control group, homeless persons suffered more often from chronic diseases (P resources of homeless people, even though homeless people seek medical care at a higher rate than controls.

    2014-02-01

    Fibre-enriched materials (FEMs) obtained from preharvest dropped apple peels were utilised as a source of dietary fibre in baked cakes and their effects on the textural/nutritional qualities and starch digestibility (glucose release behaviour, starch digestion fraction, predicted glycaemic index) of the cakes were evaluated. When FEMs were incorporated into the cake formulation (3 g and 6 g of dietary fibre per serving (100 g)), the volume of the cakes seemed to be reduced and their texture become harder. However, 3 g of FEMs did not degrade the cake qualities. The use of FEMs in cakes significantly reduced the levels of rapidly digestible starch and slowly digestible starch, while the levels of resistant starch increased. Additionally, the cake samples prepared with FEMs exhibited a lower predicted glycaemic index. This study may give rise to multi-functional bakery products with acceptable quality and low glycaemic index.

    The method reported here provides a contribution to CO 2 utilisation, nitrogen fixation and combustion exhaust cleaning using synergetic effect of electric discharge with heterogeneous catalysis on electrodes. The efficiency of CO 2 removal is about 40-65%. The process of CO 2 removal is always accompanied by NO x , VOC, SX and other component removal and is connected with O 2 formation. The final product of process is powder with fractal microstructure, low specific weight, water insoluble suitable for use as nitrogen containing fertilizer. The main component (95%) of solid product is amorphous condensate of amino acids with about 5% of metal organic compound with catalytic properties. The condensate has character of statistical proteinoid. Its creation seems to play important role during formation of life in pre-biotic Earth

    Two populations of flounder (Platichtys flesus) with different life history traits inhabit the brackish water Baltic Sea. Both types share feeding areas in coastal waters during summer-autumn but utilise different habitats for spawning in spring, namely offshore spawning with pelagic eggs and coastal spawning with demersal eggs respectively. Fecundity regulation by atresia was assessed as prevalence (portion of fish with atresia) and intensity (calculated as the average intensity of atresia in these fish) during the reproductive cycle following start of gonad development in the autumn up to spawning in spring, and evaluated in relation to fish condition (Fulton's condition factor reflecting energy reserves of the fish) and feeding incidence of the respective population. Peaking in winter (December-February), fecundity regulation was significantly higher for coastal spawning flounder than for flounder spawning offshore. For coastal spawners, the prevalence was 45-90% with an intensity of 6.4-9.3% vs. 0-25% and an intensity of 2.1-3.4% for offshore spawners during winter. Further, fecundity regulation ceased prior to spawning for offshore spawners but continued for coastal spawners. For coastal spawners, the prevalence was 12-29% and an intensity of 2.5-6.1% during spawning. The change in fish condition was strongly related to feeding incidence and differed between populations. As feeding ceased, condition of offshore spawners decreased during winter up to spawning, whereas condition of coastal spawners decreased during autumn but was maintained as feeding started again prior to spawning. Thus, habitat utilisation according to spawning strategy affects the timing of fecundity down-regulation reflecting availability of resources, namely limited food resources in deep areas and higher availability in coastal areas. Offshore spawning flounder display characteristics typical for a capital spawner with ceasing of feeding and oocyte down-regulation well before spawning

    Having previously modelled the optimal proportion of uterine cervix and corpus cancers that should be treated with brachytherapy (BT), we aimed to complete the assessment of the role of BT for gynaecological cancers by estimating the optimal proportion of vaginal cancer cases that should be treated with BT, the optimal BT utilisation (BTU) rate for vaginal cancer. We compared this with actual vaginal BTU and assessed quality of BT for vaginal cancer by a Patterns-of-Care Study (POCS). Evidence-based guidelines were used to construct an optimal BTU decision tree for vaginal cancer. Searches of the epidemiological literature to ascertain the proportion of patients who fulfilled the criteria for BT were conducted. The robustness of the model was tested by sensitivity analyses and by peer review. A retrospective POCS of BT in New South Wales (NSW) for 2003 was conducted, and actual BTU for vaginal cancer was determined. Differences between optimal and actual BTU were assessed. Quality of BT for vaginal cancer was compared with published benchmarks. The optimal vaginal cancer BTU rate was estimated to be 85% (range 81–87%). In NSW in 2003, actual vaginal cancer BTU was only 42% (95% confidence interval 22–62%). In NSW, only nine patients were treated, all with intra-vaginal cylinders, and two of four to lower than recommended doses. BT for vaginal cancers is under utilised in NSW compared with the proposed optimal models of care. BT quality may have been suboptimal and this may relate to the rarity of this disease.

    It is well-established that low socioeconomic status (SES) influences one's health status, morbidity and mortality. Housing type has been used as an indicator of SES and social determinant of health in some studies. In Singapore, home ownership is among the highest in the world. Citizens who have no other housing options are offered heavily subsidised rental housings. Residents staying in such rental housings are characterised by low socioeconomic status. Our aim is to review studies on the association between staying in public rental housing in Singapore and health status. A PubMed and Scopus search was conducted in January 2017 to identify suitable articles published from 1 January 2000 to 31 January 2017. Only studies that were done on Singapore public rental housing communities were included for review. A total of 14 articles including 4 prospective studies, 8 cross-sectional studies and 2 retrospective cohort studies were obtained for the review. Topics addressed by these studies included: (1) Health status; (2) Health seeking behaviour; (3) Healthcare utilisation. Staying in public rental housing was found to be associated with poorer health status and outcomes. They had lower participation in health screening, preferred alternative medicine practitioners to western-trained doctors for primary care, and had increased hospital utilisation. Several studies performed qualitative interviews to explore the causes of disparity and concern about cost was one of the common cited reason. Staying in public rental housing appears to be a risk marker of poorer health and this may have important public health implications. Understanding the causes of disparity will require more qualitative studies which in turn will guide interventions and the evaluation of their effectiveness in improving health outcome of this sub-population of patients.

    To study the demography, clinical characteristics, service utilisation, mortality, and predictors of mortality in older residential care home residents with advanced cognitive impairment. Cohort longitudinal study. Residential care homes for the elderly in Hong Kong West. Residents of such homes aged 65 years or more with advanced cognitive impairment. In all, 312 such residential care home residents (71 men and 241 women) were studied. Their mean age was 88 (standard deviation, 8) years and their mean Barthel Index 20 score was 1.5 (standard deviation, 2.0). In all, 164 (53%) were receiving enteral feeding. Nearly all of them had urinary and bowel incontinence. Apart from Community Geriatric Assessment Team clinics, 119 (38%) of the residents attended other clinics outside their residential care homes. In all, 107 (34%) died within 1 year; those who died within 1 year used significantly more emergency and hospital services (P<0.001), and utilised more services from community care nurses for wound care (P=0.001), enteral feeding tube care (P=0.018), and urinary catheter care (P<0.001). Independent risk factors for 1-year mortality were active pressure sores (P=0.0037), enteral feeding (P=0.008), having a urinary catheter (P=0.0036), and suffering from chronic obstructive pulmonary disease (P=0.011). A history of pneumococcal vaccination was protective with respect to 1-year mortality (P=0.004). Residents of residential care homes for the elderly with advanced cognitive impairment were frail, exhibited multiple co-morbidities and high mortality. They were frequent users of out-patient, emergency, and in-patient services. The development of end-of-life care services in residential care homes for the elderly is an important need for this group of elderly.

    2013-01-01

    Aim: The purpose of the survey was to evaluate the utilisation of the Virtual Environment for Radiotherapy Training (VERT) in clinical radiotherapy centres across the UK. Methods: A survey questionnaire was constructed using the Survey Monkey™ tool to evaluate the utilisation of the Virtual Environment for Radiotherapy Training. Once constructed, an online link to the survey questionnaire was emailed to all radiotherapy centre managers in the UK (n = 67) who were invited to provide one response per centre. The survey comprised forty-five questions which were grouped into eleven sections. Key results: The results indicate that 61% of UK radiotherapy centres have VERT installed, twenty centres are currently without a VERT installation and only 1 centre is intending to install a system in the near future. The results also indicate that the use of VERT varies considerably in differing radiotherapy centres with the most frequent use of VERT being for the training of staff, specifically for the training of pre-registration therapeutic radiographers and preparation time for trainers. The majority of centres using VERT for any of the purposes investigated feel it provides benefits. Conclusions and recommendations: The survey highlighted the varied use of VERT in radiotherapy centres across the UK and indicated that when VERT is used in clinical radiotherapy centres, a wide variety of benefits are experienced. Because of the variation in use, it is concluded that the benefits of the VERT installations in radiotherapy centres across the UK are not being fully realised. It is recommended that all radiotherapy service managers commit adequate resources to develop and implement VERT fully and effectively so that its full potential is realised in all radiotherapy centres across the UK

    The aim of this study was to evaluate differences in efficiency of feed utilisation between buffalo calves with low and high residual feed intake (RFI) by comparing feed intake, nutrient digestibility, growth traits and blood metabolites. Eighteen male Murrah buffalo calves (aged 4-6 months; 70 ± 1.0 kg body weight) were fed ad libitum with a total mixed ration for 120 d. Based on linear regression models involving dry matter intake (DMI), average daily gain (ADG) and mid-test metabolic body size, calves were assigned into low and high RFI groups. The RFI varied from -0.33 to +0.28 kg DM/d with an average RFI of -0.14 and 0.14 kg DM/d in low and high RFI calves, respectively. Calves had a mean DMI of 1.9 and 2.4 kg/d and an ADG of 0.5 and 0.6 kg/d in low and high RFI groups, respectively. Low RFI calves ate 19.0% less DM each day and required significantly less metabolisable energy for maintenance compared with high RFI calves (12.5 vs. 16.7 MJ/d). Nutrient digestibility and nitrogen balance did not differ among low and high RFI calves. In more efficient animals (low RFI calves) higher (p calves are more efficient in feed utilisation and the differences in blood metabolites are probably due to differences in feed intake and body metabolism.

    Full Text Available Improving maternal health was one of the eight Millennium Development Goals (MDGs and now it is one of the targets of 17 point Sustainable Development Goals (SDGs. The utilisation of Maternal Health Care Services (MHCSs is a complex phenomenon and it is influenced by several factors, like-health care seeking behaviour of the cohorts belonging to different socio-economic and cultural background, distance of the facility centres, type and conditions of the roads including undulating surface, transportation cost, type and availability of transportation mode along with the factors related to the accountability and surveillances of the health care services. Therefore, clear understanding and discussion is needed to draw an association between MHCSs and its influential factors. The objectives of the study are to estimate the impact of accessibility on the underserved status of MHCSs and on the utilisation of MHCSs through paucity index. In addition, the study aims to evaluate the causal relationships between underserved situation and obstacle score with the paucity index of MHCS utilisation. The empirical observation unfolds that the provision and utilisation of MHCSs are strongly dependent on accessibility and distance. The situation is aggravating for proper delivery of services, which is responsible for the increasing obstacle score and paucity index, especially in remote sub- centres of Murarai-II C.D. Block of Birbhum District.

    The worldwide coal resources have an energy supply potential of several hundred years. However, great depths, thin seams and tectonic faults may greatly restrict the utilisation of the coal seams by means of conventional conveyor technologies. With the aim of production of a conveyable synthesis gas underground coal gasification (UCG) offers an environmentally friendly and economically viable possibility of utilisation of previously inaccessible coal deposits. The high-calorific UCG synthesis gas can be used, for example, for the generation of electricity in an integrated gas and steam turbine process (GaS) as well as the production of chemical starting materials. One possibility of product recovery from the UCG synthesis gas is the production of the fertiliser carbamide (CH{sub 6}N{sub 2}O{sub 2}). The aim of this study is the development of a utilisation concept for coal deposits on the basis of a combined and energy-independent UCG-GaS-urea process. To check the utilisation concept based on an independent electricity supply an economic feasibility study for a selected investigation area in the north of Bangladesh was carried out with consideration of the economic viability and potential of the UCG-GaS-urea process.

    Indigenous infants (infants aged under 12 months) have the highest hospital admission and emergency department presentation risks in Australia. However, there have been no recent reports comparing hospital utilisation between Indigenous and non-Indigenous infants. Our primary objective was to use a large prospective population-based linked dataset to assess the risk of all-cause hospital admission and emergency department presentation in Indigenous compared to non-Indigenous infants in Western Australia (WA). Secondary objectives were to assess the effect of socio-economic status (Index of Relative Socio-Economic Disadvantage [IRSD]) on hospital utilisation and to understand the causes of hospital utilisation. There were 3,382 (5.4%) Indigenous and 59,583 (94.6%) non-Indigenous live births in WA from 1 January 2010 to 31 December 2011. Indigenous infants had a greater risk of hospital admission (adjusted odds ratio [aOR] 1.90, 95% confidence interval [95% CI] 1.77-2.04, p = disadvantaged (IRSD 1) infants in the total cohort (35.7%) was similar to the risk in the least disadvantaged (IRSD 5) infants (30.6%) (aOR 1.04, 95% CI 0.96-1.13, p = 0.356). WA Indigenous infants have much higher hospital utilisation than non Indigenous infants. WA health services should prioritise Indigenous infants regardless of their socio economic status or where they live.
