Population Structure and Evolution after Speciation of the Hokkaido Salamander (Hynobius retardatus.

Directory of Open Access Journals (Sweden)

Masatoshi Matsunami

Full Text Available The Hokkaido salamander (Hynobius retardatus is endemic to Hokkaido Island, Japan, and shows intriguing flexible phenotypic plasticity and regional morphological diversity. However, to date, allozymes and partial mitochondria DNA sequences have provided only an outline of its demographic histories and the pattern of its genetic diversification. To understand the finer details of the population structure of this species and its evolution since speciation, we genotyped five regional populations by using 12 recently developed microsatellite polymorphic markers. We found a clear population structure with low gene flow among the five populations, but a close genetic relationship between the Teshio and Kitami populations. Our demographic analysis suggested that Teshio and Erimo had the largest effective population sizes among the five populations. These findings regarding the population structure and demography of H. retardatus improve our understanding of the faunal phylogeography on Hokkaido Island and also provide fundamental genetic information that will be useful for future studies.

OpenAIRE

Komatsu, Tsutomu; Shinmura, Akinori; Kondo, Norio

2016-01-01

Strains of the bacterium Xylophilus ampelinus were collected from Europe and Hokkaido, Japan. Genomic fingerprints generated from 43 strains revealed four DNA types (A-D) using the combined results of Rep-, ERIC-, and Box-PCR. Genetic variation was found among the strains examined; strains collected from Europe belonged to DNA types A or B, and strains collected from Hokkaido belonged to DNA types C or D. However, strains belonging to each DNA type showed the same pathogenicity to grapevines ...

Full text: The recent growth of wind facilities in Japan has raised concerns about bird collisions, especially for white-tailed eagles in Hokkaido, northern part of Japan. Approx. 150 pairs of white-tailed eagles breed in Hokkaido in the latest survey (Shiraki unpub. data) and these pairs are considered as residents. On the other hand, ca.500-700 white-tailed eagles including migrants from the breeding areas in Russia winter in Hokkaido. The major objectives of this study are to (1) examine the impacts of wind turbines on white-tailed eagles by information analysis in the previous accident reports of the collisions and by field investigations at the wind facilities, and (2) explore the possible factors which relate to the collisions of the eagles with wind turbines A total of 24 collisions of sea eagles (Haliaeetus spp.) have been reported by both incidental discoveries and fatality searching since 2004 in Hokkaido. 22 of the 24 fatalities were white-tailed eagles and 23 of the 24 were immature birds. Field surveys to estimate of fatality rate of white-tailed eagles and observations of the flight behaviours were carried out at the wind facilities including a total of 42 turbines for one and half years. Annual mortality for white-tailed eagles was estimated at 0.08 fatalities / yr / MW and the Risk Index (Smallwood et Thelander 2004) was calculated at 0.058, the second highest value after common buzzards (Buteo buteo) in this survey. In addition, white-tailed eagles and common buzzards flew at the altitudes of rotor zones of the wind turbines more frequently than the other raptors. The effects of the collisions at wind turbines on white-tailed eagles in Hokkaido based on the results of this study, and on the ecological and the genetically information of the population will be considered in the presentation.

Immature intra-oceanic arc-type volcanism on the Izanagi Plate revealed by the geochemistry of the Daimaruyama greenstones in the Hiroo Complex, southern Hidaka Belt, central Hokkaido, Japan

The Izanagi Plate is assumed to have underlain the western Panthalassa Ocean to the east of Eurasia, and to have been subducting under the Eurasian continent. Although the Izanagi Plate has been lost to subduction, the subduction complexes of the circum-Panthalassa continental margins provide evidence that subduction-related volcanism occurred within the Panthalassa Ocean, and not just along its margins. The Daimaruyama mass is a kilometer-sized allochthonous greenstone body in the Hiroo Complex in the southeastern part of the Nakanogawa Group in the southern Hidaka Belt, northern Japan. The Hiroo Complex is a subduction complex that formed within the Paleo-Kuril arc-trench system at 57-48 Ma. The Daimaruyama greenstones consist mainly of coarse volcaniclastic rocks with lesser amount of lava. Red bedded chert, red shale, and micritic limestone are also observed as blocks associated with the greenstones. The presence of Early Cretaceous (Aptian-Albian) radiolaria in red bedded cherts within the greenstones indicates that the Daimaruyama greenstones formed after this time. An integrated major and trace element geochemical dataset for whole-rocks and clinopyroxenes of the greenstones indicates a calc-alkaline magmatic trend with low TiO2 contents and increases in SiO2 and decreases in FeO* with increasing differentiation. Negative anomalies of Nb, Ta, and Ti in normal mid-ocean-ridge basalt type normalized patterns are interpreted as "arc-signatures". Using "rhyolite-MELTS", we conducted a numerical simulation of magmatic differentiation under conditions of 1.5 kbar and H2O = 3 wt% to reproduce the liquid line of descent of the Daimaruyama greenstones. Back-calculations of the equilibrium melt compositions from the trace element chemistry of the clinopyroxenes generally agree with the whole-rock rare earth element compositions of the Daimaruyama greenstones, therefore providing support for the conditions used for the rhyolite-MELTS calculations as well as the actual

A survey on stroke was conducted to evaluate the incidence of intracerebral hemorrhage and the prevalence of risk factors. The subjects, comprising those patients who suffesed a stroke, were registered on the Northern Hokkaido Stroke Study between July 2002 and June 2006. The severity of their illness was rated by the National Institutes of Health Stroke Scale (NIHSS) at hospital admission, while their outcome was determined by the mortality within 3 months and the mRS (modified Rankin Scale score). Of the 1,046 registered stroke patients, 271 (25.9%) were found to suffer from cerebral hemorrhage. Their mean age was 70.3±11.7 years; male-to-female ratio, 154/117; mean NIHSS at admission, 11.8±8.1; mortality within 3 months, 19.2%; and percentage who regained independence within 3 months (mRS: ≤2), 32.5%. A history of hypertension was found in 72.6%, and 13.7% had no treatment. MRI (T2*) revealed micro-hemorrhage outside the lesions in 67.5%. Forty-seven patients (17.3%) were taking anti-platelet agents at the onset of intracerebral hemorrhage. There was no significant difference between the mortalities of the anti-platelet-agent-users and non-users but the percentage of those regaining independence within 3 months was 19.1% for the users against 37.3% for the non-users (p=0.0177), with a significantly poor outcome in the user group. In northern Hokkaido, the incidence of cerebral hemorrhage remains high, and the percentage of those with poorly controlled or uncontrolled hypertension was 30%. These findings suggest a need to educate not only the inhabitants themselves but also the physicians engaged in their care. (author)

Population structures of the red fox (Vulpes vulpes) on the Hokkaido Island, Japan, revealed by microsatellite analysis.

2011-01-01

In order to examine the population structures of the red fox (Vulpes vulpes) on the Hokkaido Island in Japan, we conducted analysis on 250 foxes from all over the island for 12 microsatellite loci. Assignment tests using the genotype data set showed that they were divided into 6 subpopulations. Of the 6, one was geographically isolated in the southern region and considered definitive subpopulation, whereas the other 5 were not. The slight differences among the latter 5 subpopulations were explained by the high adaptability and long dispersal of the red fox on the Hokkaido Island. Although there are few ecological data to explain the genetic differentiation of the southern population, we have proposed some hypotheses from the present ecological and geohistorical viewpoints. One convincing reason from the ecological viewpoint is the restriction of gene flow to southern Hokkaido from other areas due to geographical isolation resulting from the land shape. The other explanation is the geohistorical division of southern Hokkaido from other regions on the island during the last interglacial age, resulting in the isolation of the fox population.

The red-crowned crane (Grus japonensis) is recognized internationally as an endangered species. Migratory populations breed in eastern Russia and northeastern China, whereas the resident population inhabits the island of Hokkaido, Japan. Although the population inhabiting Hokkaido had experienced a severe bottleneck by the end of the 19th century, the population size has recovered to about 1500 and continues to increase now thanks to conservation efforts. A previous study reported that no marked genetic differences were seen in the island population, and that the genetic variation of the whole population on Hokkaido was lower than that of the continental population. However, the precise genetic structure of the island population in the past or near present remains unclear. To better understand the spatiotemporal changes in the genetic structure of the island population, we performed mitochondrial DNA (mtDNA) analyses using stuffed specimens (years 1878-2001) and tissue or blood samples (years 1970-2014). We found three haplotypes in the island population, one of which was a novel mtDNA haplotype in 1997 and 2007 samples. In addition, there was no clear difference in the haplotype frequency through the time span. These results suggest that the low genetic variation of the island population persisted for the last hundred years. It is thus nearly impossible for the island population to recover its genetic variation in isolation. Conservation plans for this species should therefore include the promotion of genetic exchanges between the continental and island populations, such as through artificial introduction to Hokkaido.

Red-crowned cranes (Grus japonensis) are native to eastern Hokkaido (island population), in contrast to the mainland, which migrates between the Amur River basin and eastern China-Korea peninsula. During the 1990s we found that Red-crowned cranes in Hokkaido were highly contaminated with mercury: however, the source was unknown. We investigated the time trend of mercury contamination in Red-crowned cranes. Total mercury levels in the livers and kidneys from cranes dead in the 2000s were lower than those dead in the 1990s. Feather is a major pathway of mercury excretion for many bird species and is used as an indicator of blood mercury level during feather growth. As internal organs from the specimens collected before 1988 were not available, we analyzed the flight feather shavings from stuffed Red-crowned cranes dead in 1959-1987 and found that the mercury level of feathers from cranes dead in the 1960s and 1970s was not more than those from the cranes dead in the 2000s. These results suggest that mercury contamination in Red-crowned cranes in Hokkaido decreased temporally during the 1990s-2000s. This indicates the possible occurrence of some mercury pollution in Red-crowned cranes' habitat in this region in the 1990s or before.

This paper outlines the newly prepared geothermal gradient map (GGM) of Hokkaido which is important for survey on geothermal and hot spring resources. The temperature data of 687 wells were compiled by data collection and field survey. The geothermal gradient was calculated from the ratio of the temperature difference between the bottom (deepest well log) and the ground surface (10degC) to a bottom depth. GGM was prepared using data of 85 wells which show real geothermal temperatures through conductive temperature profiles, or SBHT (static bottom hole temperature) calculation is possible. Geological profiles were classified into three types based on base rocks. The thermal structure of GGM was clearly divided into a high geothermal gradient over 10degC/100m, and a low one within 3degC/100m. The former showed active volcano and high geothermal areas, while the latter showed a volcanic front arc area. This underground temperature structure relates to the formation process of volcanos and the origin of magma, and is also similar to the trend of a crust thermal flow rate. The geothermal gradient increases with a decrease in Curie point depth. 26 refs., 10 figs., 2 tabs.

We have studied nuclear power plant for district heating. Already some towns and villages in Hokkaido have requested small reactor for district heating. Using existing technology allows us to shorten development period and to keep a lid on development cost. We decided to develop new reactor based on 'MUTSU' reactor technology. 'MUTSU' had already proved its safety. And 'MUTSU' reactor was boron free reactor. It allows plant system to become more compact and simple. And load following capability by core reactivity become bigger. It means to reduce control rod movement. It leads to dependability enhancement. We calculated burn-up calculation of erbium addition fuel. In the result the core life became about 10 years. In the district heating system, there are not only district heating but also snow melting with warm water. It uses steam condenser's heat, which are only discharged now. This small plant has passive safety system. It is natural cooling of containment vessel. In case of loss of coolant accident, decay heat can remove by natural convection air cooling after 6 hours. Decay heat within 6 hours can remove by evaporative heat transfer of pool on containment vessel. (author)

SuperDARN Hokkaido radar observation of westward flow enhancement in subauroral latitudes

Full Text Available Westward flow enhancement in subauroral latitudes is investigated based on the first one and a half year observation of the SuperDARN Hokkaido radar. A total of 15 events are identified with the criteria of westward flow speed of >1.0 km/s in magnetic latitude from 45 to 65 deg during geomagnetically disturbed period of Kp>3+ at 20 magnetic local time. It is found that especially during the storm recovery phase, the flow enhancement occurs in broad range of Dst amplitude, and the occurrence latitude depends on the amplitude of Dst. It is also found that the disturbed Kp condition is not sufficient for the appearance of the subauroral flow enhancement as seen by Hokkaido radar while storm-like Dst condition is necessary, supporting the idea that ring current particles play an essential role to enhance the westward flow in subauroral latitudes via magnetosphere-ionosphere coupling through the field-aligned current.

The Northern Japan arc is characterized by fast subduction of old oceanic lithosphere. The high density instrumentation and high seismicity make this an ideal natural laboratory to study the interplay between subduction zone dynamics, dehydration, migration of fluids, and seismogenesis. In this study we use high resolution finite element models to predict the thermal structure of the subduction slab below Tohoku (Northern Honshu) and Hokkaido. These models allow us to predict the pressure, temperature and mineralogy of the subducted crust and mantle. We use these models to predict the (p,T) conditions of earthquakes that are relocated with a precision of around 1 km by double difference techniques. Below Northern Hokkaido and Tohoku we find that the earthquake activity is strong in crust and the uppermost mantle for temperatures seismic moment. The strongest 3D variations in this arc occur below southern Hokkaido. This 200 km wide region is characterized by a change in trench geometry, anomalously low heatflow and an anomalous velocity structure in the mantle wedge. Tomographic imaging suggest that continental crust is subducted to significant depth, thereby insulating the subducting slab from the hot mantle wedge at least at intermediate depths. The thermal insulation is also suggested by the deepening of the earthquakes in the slab (Kita et al., EPSL, 2010). This region may be characterized by active crustal erosion which would lead to a further blanketing of the crust by a sedimentary layer. Further modifications in thermal structure are possible due to the 3D wedge flow that is generated by the along-arc variations in trench geometry. We quantitatively verify the relative importance of these processes using 2D and 3D dynamical models. Without the seismically imaged crustal structure the earthquake temperatures are significantly elevated compared to the Tohoku and (northern) Hokkaido sections. If we take the modified crustal structure into account we find a (p

Babesiosis is a tick-borne protozoan disease affecting many mammalian species worldwide, caused by the intraerythrocytic multiplication of Babesia spp. The present study aimed to detect the presence of Babesia sp. in 13 American mink from Hokkaido, Japan. One of 13 animals was positive, as indicated by nested PCR targeting the 18S ribosomal RNA (SSU rDNA) and subunit 7 (eta) of the chaperonin-containing t-complex polypeptide 1 (CCT7) genes from species of Babesia and Theileria. Sequencing of the PCR product of SSU rDNA revealed 99% homology to the isolates of Babesia sp. SAP#131 found in raccoons in Hokkaido, whereas that of the CCT7 gene showed 80% homology to the isolates of Babesia gibsoni in dogs as determined by BLAST analysis. We refer to the cognate sequence as Babesia sp. NV-1. Phylogenetic analyses of SSU rDNA and CCT7 genes from Babesia sp. NV-1 revealed them to be most closely related to the Babesia sp. SAP#131 from a raccoon in Hokkaido and to canine B. gibsoni, respectively. Here, we provide the first molecular evidence of the Babesia sp. NV-1 parasite in feral American mink ( Neovison vison ) in Hokkaido, Japan.

The Red-crowned Crane Grus japonensis is an endangered species that has two separate breeding populations, one in the Amur River basin and the other in north and east Hokkaido, Japan. So far, only two (Gj1 and Gj2) and seven (Gj3-Gj9) haplotypes in D-loop of mtDNA were identified in Japan and in the continent, respectively. We obtained feathers from three cranes found in northeast Honshu. The crane in Akita in 2008, which also arrived at west Hokkaido, had a novel haplotype (Gj10). Another crane in Akita in 2009 showed a heteroplasmy (Gj7 and a novel type, Gj12). The third crane in Miyagi in 2010 also showed another type, Gj11. These results suggest that three Red-crowned Cranes appeared in Honshu and west Hokkaido were from the continent.

The number of wild sika deer (Cervus nippon yesoensis) continues to increase in Hokkaido Prefecture, Japan. The major concern for the livestock industry is the transmission of pathogens between sika deer and cattle. Fasciolosis is an important disease that can occur in both animals. The aim of this study was to examine the possible mutual transmission of this disease in Hokkaido Prefecture. A total of 105 Fasciola flukes were obtained from sika deer and 96 from domestic cattle. The Fasciola flukes in Japan are reported to possess no mature sperm. However, in this study, 14 flukes from sika deer and eight flukes from cattle contained mature sperm in their seminal vesicles. All the Fasciola flukes from the two host animals had Fh/Fg type in nuclear phosphoenolpyruvate carboxykinase (pepck) gene, with a mixed fragment pattern derived from F. hepatica and F. gigantica, which are considered to be hybrid Fasciola flukes. However, almost all the flukes had Fsp1 haplotype in NADH dehydrogenase subunit 1 (nad1) gene, indicating that their maternal lineage was F. hepatica. A new haplotype, Fsp3, was detected in one fluke obtained from cattle and differed in one nucleotide from Fsp1. Therefore, the Fasciola flukes detected in both host species had almost identical molecular characteristics. These findings suggest the mutual transmission of Fasciola flukes between sika deer and domestic cattle in Hokkaido. Copyright © 2017. Published by Elsevier B.V.

Applications of satellite data to the studies of agricultural meteorology, 3: District classification and local temperature estimation by GMS IR data

In estimating air temperature using ground temperature from GMS IR data, ground effect corrections are equally important as atmospheric effect corrections. However, ground effect corrections are very difficult to conduct, requiring a great amount of analyses because of complicated relationship between air temperatures and ground temperatures.In our previous study (Tani et al, 1984), it was found that the classification of AMeDAS meteorological sites using deviation between temperatures estimated from the GMS IR data and those obtained from AMeDAS data, indicated that meteorological sites of the same type tend to form groups. This shows that the accuracy of temperature estimations increases when the estimation is carried out by small districts. The classification of AMeDAS meteorological sites in Hokkaido was conducted by cluster analysis using temperature deviations. The following two kinds of data were used for the cluster analysis: sixty-one GMS IR data and AMeDAS data collected from 1979 through 1984. Mean deviations between the temperatures estimated from GMS IR data obtained at three hour intervals and those obtained from AMeDAS data were calculated. Using these deviations, cluster analyses of AMeDAS meteorological sites were made. The results are shown in Fig. 2. Furthermore, AMeDAS meteorological sites were classified based on the deviations between the time average temperatures of AMeDAS and the time temperature of AMeDAS. The results are shown in Fig. 3.Using the results of this classification, temperatures of the five districts were estimated, shown in Figs. 2 and 3. The temperature estimations of the five districts were conducted using four methods (six different calculation methods) and the accuracies clarified.1) The regression equation of surface temperature from GMS data and AMeDAS temperature was calculated throughout Hokkaido island. The regression equation was applied to five districts. (named One-equation method)2) The regression equations were

Nuclear reaction data are necessary and applicable for many application fields. The nuclear reaction data must be compiled into a database for convenient availability. One such database is the EXFOR database maintained by the International Network of Nuclear Reaction Data Centres (NRDC). As a member of the NRDC, the Hokkaido University Nuclear Reaction Data Centre (JCPRG) compiles charged-particle induced reaction data and contributes about 10 percent of the EXFOR database. In this paper, we show the recent compilation status and related research topics of JCPRG. (author)

Upper Triassic limestones from the northern part of Japan: new insights on the Panthalassa Ocean and Hokkaido Island

In comparison with the well-known Tethyan domain, Upper Triassic limestones from the Panthalassa Ocean are still poorly known. However, these carbonates represent a unique opportunity to have a more accurate view of the Panthalassa Ocean during the Triassic. Their study will allow comparison and correlation of biotic assemblages, biostratigraphy, diagenesis, and depositional settings of different Triassic localities from Tethyan and Panthalassic domains. Moreover, investigation of these carbonates will provide data for taxonomic revisions and helps to better constrain palaeobiogeographic models. One of the best targets for the study of these carbonates is Hokkaido Island (north of Japan). Indeed, this island is a part of the South-North continuity of Jurassic to Paleogene accretionary complexes, going from the Philippines to Sakhalin Island (Far East Russia). Jurassic and Cretaceous accretionary complexes of Japan and Philippines contain Triassic mid-oceanic seamount carbonates from the western Panthalassa Ocean (Onoue & Sano, 2007; Kiessling & Flügel, 2000). They have been accreted either as isolated limestone slabs or as clasts and boulders, and are associated with mudstones, cherts, breccias and basaltic rocks. Two major tectonic units forming Hokkaido Island and containing Triassic limestones have been accurately explored and extensively sampled: the Oshima Belt (west Hokkaido) a Jurassic accretionary complex, and the Cretaceous Sorachi-Yezo Belt (central Hokkaido). The Sorachi-Yezo Belt is composed of Cretaceous accretionary complexes in the east and of Cretaceous clastic basin sediments deposited on a Jurassic basement in the west (Ueda, 2016), both containing Triassic limestones. The origin of this belt is still matter of debate especially because of its western part which is not in continuity with any other accretionary complex known in the other islands of Japan and also due to the lack of data in this region. One of the main goals of this study is to

As a result of the limited application of portable X-ray fluorescence (pXRF) in archaeological research in Japan it is necessary to compare this technique to proven, laboratory-based, analytical techniques. In this study instrumental neutron activation analysis, inductively-coupled plasma mass spectrometry, and electron probe microanalysis are used to validate pXRF and determine the overall suitability of this technique for archaeological obsidian provenance studies in Hokkaido, northern Japan. Furthermore, the results of this study are compared to previously published data to assess reproducibility and compatibility. This study demonstrates the reliability of pXRF for the rapid characterization of Hokkaido obsidian while contributing to the ongoing evaluation of the applicability of 'off-the-shelf' pXRF to obsidian provenance research in archaeology.

A district heating and snow melting system utilizing waste heat from Gas Turbine High temperature Gas Reactor of 300 MW_e (GTHTR300), a heat-electricity cogeneration design of high temperature gas-cooled reactor, was analyzed. Application areas are set in Sapporo and Ishikari, the heavy snowfall cities in Northern Japan. The heat transport analyses are carried out by modeling the components in the system; pipelines of the secondary water loops between GTHTR300s and heat demand district and heat exchangers to transport the heat from the secondary water loops to the tertiary loops in the district. Double pipe for the secondary loops are advantageous for less heat loss and smaller excavation area. On the other hand, these pipes has disadvantage of more electricity consumption for pumping. Most of the heat demand in the month of maximum requirement can be supplied by 2 GTHTR300s and delivered by 9 secondary loops and around 5000 heat exchangers. Closer location of GTHTR300 site to the heat demand district is largely advantageous economically. Less decrease of the distance from 40 km to 20 km made the heat loss half and cost of the heat transfer system 22% smaller. (author)

We decided to develop new reactor based on 'MUTSU' reactor technology because 'MUTSU' had already proved its safety. And this reactor was boron free reactor. It allows plant system to reduce the chemical control system. And moderator temperature coefficient is deeply negative. It means to improve its operability and leads to dependability enhancement. We calculated burn-up calculation of erbium addition fuel. In the result, the core life became about 10 years. And we adapt the cassette type refueling during outagein in order to maintain nonproliferation. In the district heating system, a double heat exchanger system enables to response to load change in season. To obtain the acceptance of public, this system has a leak prevention system of radioactive materials to public. And road heating system of low grade heat utilization from turbine condenser leads to improve the heat utilization efficiency. We carried out performance evaluation test of district heating pipeline. Then the heat loss of pipeline is estimated at about 0.440degC/km. This result meets general condition, which is about 1degC/km. This small plant has passive safety system. It is natural cooling of containment vessel. In case of loss of coolant accident, decay heat can remove by natural convection air cooling after 6 hours. Decay heat within 6 hours can remove by evaporative heat transfer of pool on containment vessel. (author)

Remote Triggering of the Mw 6.9 Hokkaido Earthquake as a Result of the Mw 6.6 Indonesian Earthquake on September 11, 2008

Full Text Available Only just recently, the phenomenon of earthquakes being triggered by a distant earthquake has been well established. Yet, most of the triggered earthquakes have been limited to small earthquakes (M < 3. Also, the exact triggering mechanism for earthquakes is still not clear. Here I show how one strong earthquake (Mw = 6.6 is capable of triggering another (Mw = 6.9 at a remote distance (~4750 km. On September 11, 2008, two strong earthquakes with magnitudes (Mw of 6.6 and 6.9 hit respectively in Indonesia and Japan within a short interval of ~21 minutes time. Careful examination of broadband seismograms recorded in Japan shows that the Hokkaido earthquake occurred just as the surface waves generated by the Indonesia earthquake arrived. Although the peak dynamic stress estimated at the focus of the Hokkaido earthquake was just reaching the lower bound for the capability of triggering earthquakes in general, a more plausible mechanism for triggering an earthquake might be attributed to the change of a fault property by fluid infiltration. These observations suggest that the Hokkaido earthquake was likely triggered from a remote distance by the surface waves generated from the Indonesia earthquake. If some more cases can be observed, a temporal warning of possible interaction between strong earthquakes might be concerned in the future.

Serological survey of Rhodococcus equi infection in horses in Hokkaido was performed using ELISA. Of 2,879 horse sera, 318 (11.0%) gave antibody-positive (OD greater than or equal to 0.3) reactions. The antibody-positive rate of female was significantly higher (p less than 0.01) than that of male, and no statistical difference between Anglo-Arab and thoroughbred was detected in the antibody-positive rate. The maximum antibody-positive rate (27.1%) was shown at 14 years of age. The antibody-positive rates on the 160 farms were found to vary widely from 0 to 78.9%. A significant difference (p less than 0.01) in the antibody-positive rate was detected among horse farms. It was elucidated that 100 (62.5%) out of 160 horse farms had an antibody-positive horse. These results indicate that R. equi was widespread on horse farms, and the level of environmental contamination with R. equi differed among horse farms.

The Hokkaido Electric Power Co., Inc., aiming to enhance power generation efficiency through power load levelling, strives to expand and substantiate its electricity billing menu and to popularize and encourage the use of levelling-oriented apparatuses and systems most of which are designed for utilizing midnight power. The billing menu has in it a snow-melting power which is cut off for load levelling during the peak demand time zone. For domestic use, a time zone-specified lighting system named Dream Eight is created, which is one of the billing systems dependent upon time zone. Introduced therein for industrial use is a demand/supply adjustment contract system. Furthermore, in compliance with the amended Electricity Business Law that came into force in 1995, efforts are under way for revising the period wherein power is to be supplied for melting snow, expanding the scope of application of the power supply system dependent upon time zone, and newly introducing a heat accumulation assisted peak adjustment contract system and an operation adjustment contract system. As for business efforts in relation to load levelling, the company proposes household electrical systems centering about 200V high-efficiency apparatuses, electric water warmer contributing to the enhancement of year-round load levelling, popularization and reinforcement of electric snow melting systems, and power utilizing technologies capable of meeting local demands raised for example by agriculture and fishery.

The purpose of the present study is to construct a nation-wide forensic soil database, which allows for the identification of soil evidence based on heavy element and heavy mineral signatures determined by two synchrotron radiation (SR) X-ray techniques, i.e., a high-energy synchrotron radiation X-ray fluorescence analysis and a synchrotron-radiation X-ray powder diffraction analysis, respectively. The heavy element and heavy mineral compositions of the stream sediments collected at 3024 points located all over Japan were measured by the two SR X-ray techniques. The present paper focuses on a regional characterization of the sediments collected from the Hokkaido areas. The concentrations of heavy elements and heavy minerals in the Hokkaido areas were visualized as maps that enable us to compare the heavy element and heavy mineral compositions with the geological context of the samples. Based on a hierarchical cluster analysis using the semi-quantitative compositions of the heavy minerals, we could successfully classify the sediments into six groups corresponding to their background geologies. A Bonferroni multiple comparison demonstrated that these six groups also have significant differences in the heavy element composition. From these examinations, we could demonstrate that detailed regional identification of unknown samples is possible by analyzing both heavy element and heavy mineral compositions of each sample.

Renewable natural resources, such as solar radiation, rainfall, wind, and geothermal heat, together with ecosystem services, provide the elementary supports for the sustainable development of human society. To improve regional sustainability, we studied the spatial distributions and quantities of renewable natural resources and net primary productivity (NPP) in Hokkaido, which is the second largest island of Japan. With the help of Geographic Information System (GIS) software, distribution maps for each type of renewable natural resource were generated by kriging interpolation based on statistical records. A composite map of the flow of all types of renewable natural resources was also generated by map layer overlapping. Additionally, we utilized emergy analysis to convert each renewable flow with different attributes into a unified unit (i.e., solar equivalent joules [sej]). As a result, the spatial distributions of the flow of renewable natural resources of the Hokkaido region are presented in the form of thematic emergy maps. Thus, the areas with higher renewable emergy can be easily visualized and identified. The dominant renewable flow in certain areas can also be directly distinguished. The results can provide useful information for regional sustainable development, environmental conservation and ecological management.

Hayakawa, T., Hirano, H. 2013. A revised inoceramid biozonation for the Upper Cretaceous based on high-resolution carbon isotope stratigraphy in northwestern Hokkaido, Japan. Acta Geologica Polonica, 63 (2), 239-263. Warszawa. Biostratigraphic correlations of inoceramid bivalves between the North Pacific and Euramerican provinces have been difficult because the inoceramid biostratigraphy of the Japanese strata has been based on endemic species of the northwest Pacific. In this study, carbon stable isotope fluctuations of terrestrial organic matter are assembled for the Upper Cretaceous Yezo Group in the Haboro and Obira areas, Hokkaido, Japan, in order to revise the chronology of the inoceramid biozonation in Japan. The carbon isotope curves are correlated with those of marine carbonates in English and German sections with the aid of age-diagnostic taxa. According to the correlations of the carbon isotope curves, 11 isotope events are recognised in the sections studied. As a result of these correlations, the chronology of the inoceramid biozones of the Northwest Pacific has been considerably revised. The revised inoceramid biozones suggest that the timing of the origination and extinction of the inoceramids in the North Pacific biotic province is different from the stage/substage boundaries defined by inoceramids, as used in Europe and North America.

Estimation of seismic velocity in the subducting crust of the Pacific slab beneath Hokkaido, northern Japan by using guided waves

2014-12-01

A subducting crust contains a large amount of water as a form of hydrous minerals (e.g., Hacker et al., 2003), and the crust plays important roles for water transportation and seismogenesis in subduction zones at intermediate depths (e.g., Kirby et al., 1996; Iwamori, 2007). Therefore, the investigation of seismic structure in the crust is important to understand ongoing physical processes with subduction of oceanic lithosphere. A guided wave which propagates in the subducting crust is recorded in seismograms at Hokkaido, northern Japan (Shiina et al., 2014). Here, we estimated P- and S-wave velocity in the crust with guided waves, and obtained P-wave velocity of 6.6-7.3 km/s and S-wave velocity of 3.6-4.2 km/s at depths of 50-90 km. Moreover, Vp/Vs ratio in the crust is calculated to be 1.80-1.85 in that depth range. The obtained P-wave velocity about 6.6km/s at depths of 50-70 km is consistent with those estimated in Tohoku, northeast Japan (Shiina et al., 2013), and this the P-wave velocity is lower than those expected from models of subducting crustal compositions, such as metamorphosed MORB model (Hacker et al., 2003). In contrast, at greater depths (>80 km), the P-wave velocity marks higher velocity than the case of NE Japan and the velocity is roughly comparable to those of the MORB model. The obtained S-wave velocity distribution also shows characteristics similar to P waves. This regional variation may be caused by a small variation in thermal regime of the Pacific slab beneath the two regions as a result of the normal subduction in Tohoku and oblique subduction in Hokkaido. In addition, the effect of seismic anisotropy in the subducting crust would not be ruled out because rays used in the analysis in Hokkaido propagate mostly in the trench-parallel direction, while those in Tohoku are sufficiently criss-crossed.

A base-line survey was performed for 3,185 persons over 40 years of age in 1984 and 1985 in agricultural and piscatorial areas of Hokkaido with regards to their dietary habits and life style. Of them, 147 persons died prior to the recent follow-up survey of 1988. As a result of a case-control study of the dead with those of the followed-up group, a more frequent intake of instant noodles was indicated as significantly increasing the risk of death, even after adjusting for the health status at the base-line survey and other confounding variables (the adjusted relative risk = 1.44 per a frequency class, p = 0.049).

Red-crowned (or Japanese) cranes Grus japonensis are native to eastern Hokkaido, Japan--the island population, and mainland Asia--the continental population that migrates from breeding grounds along the Amur River Basin to winter in east China and the Korean Peninsula. The island population was reduced to about 50-60 birds in early part of the 20th century. Since 1950s, the population has increased to more than 1,300 as a consequence of human-provided food in winter, resulted in change of their habitats and food resource. From the carcasses of 284 wild cranes from the island population, collected in Hokkaido since 1976 until 2010, we measured six physical parameters (body weight and lengths of body, wing, tarsus, tail and exposed culmen) and divided into groups by sex and three developmental stages (juvenile, yearling and adult). All parameters of males were larger than those of females at the same stage. Total body length of females tends to grow up earlier than males, in contrast to body weight. Obvious time trends were not observed in these all parameters during 34 years for these six categories measured, except total length of male juveniles, which showed a significant increasing trend. These results provide the first extensive data on body size and mass in the wild red-crowned cranes.

Stress Drops of Earthquakes on the Subducting Pacific Plate in the South-East off Hokkaido, Japan

Saito, Y.; Yamada, T.

2013-12-01

Large earthquakes have been occurring repeatedly in the South-East of Hokkaido, Japan, where the Pacific Plate subducts beneath the Okhotsk Plate in the north-west direction. For example, the 2003 Tokachi-oki earthquake (Mw8.3 determined by USGS) took place in the region on September 26, 2003. Yamanaka and Kikuchi (2003) analyzed the slip distribution of the earthquake and concluded that the 2003 earthquake had ruptured the deeper half of the fault plane of the 1952 Tokachi-oki earthquake. Miyazaki et al. (2004) reported that a notable afterslip was observed at adjacent areas to the coseismic rupture zone of the 2003 earthquake, which suggests that there would be significant heterogeneities of strength, stress and frictional properties on the surface of the Pacific Plate in the region. In addition, some previous studies suggest that the region with a large slip in large earthquakes permanently have large difference of strength and the dynamic frictional stress level and that it would be able to predict the spatial pattern of slip in the next large earthquake by analyzing the stress drop of small earthquakes (e.g. Allmann and Shearer, 2007 and Yamada et al., 2010). We estimated stress drops of 150 earthquakes (4.2 ≤ M ≤ 5.0), using S-coda waves, or the waveforms from 4.00 to 9.11 seconds after the S wave arrivals, of Hi-net data. The 150 earthquakes were the ones that occurred from June, 2002 to December, 2010 in south-east of Hokkaido, Japan, from 40.5N to 43.5N and from 141.0E to 146.5E. First we selected waveforms of the closest earthquakes with magnitudes between 3.0 and 3.2 to individual 150 earthquakes as empirical Green's functions. We then calculated source spectral ratios of the 150 pairs of interested earthquakes and EGFs by deconvolving the individual S-coda waves. We finally estimated corner frequencies of earthquakes from the spectral ratios by assuming the omega-squared model of Boatwright (1978) and calculated stress drops of the earthquakes by

The southeast part of the island of Hokkaido, Japan, is an area dominated by volcanoes and volcanic caldera. The active Usu Volcano is at the lower right edge of the circular Lake Toya-Ko and near the center of the image. The prominent cone above and to the left of the lake is Yotei Volcano with its summit crater. The city of Sapporo lies at the base of the mountains at the top of the image and the town of Yoichi -- the hometown of SRTM astronaut Mamoru Mohri -- is at the upper left edge. The bay of Uchiura-Wan takes up the lower center of the image. In this image, color represents elevation, from blue at the lowest elevations to white at the highest. The radar image has been overlaid to provide more details of the terrain. Due to a processing problem, an island in the center of this crater lake is missing and will be properly placed when further SRTM swaths are processed. The horizontal banding in this image is a processing artifact that will be removed when the navigation information collected by SRTM is fully calibrated. This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

Full Text Available Geothermal resources have become an increasingly important source of renewable energy for electrical power generation worldwide. Combined Three Dimension (3D Subsurface Temperature (SST and Land Surface Temperature (LST measurements are essential for accurate assessment of geothermal resources. In this study, subsurface and surface temperature distributions were combined using a dataset comprised of well logs and Thermal Infrared Remote sensing (TIR images from Hokkaido island, northern Japan. Using 28,476 temperature data points from 433 boreholes sites and a method of Kriging with External Drift or trend (KED, SST distribution model from depths of 100 to 1500 m was produced. Regional LST was estimated from 13 scenes of Landsat 8 images. Resultant SST ranged from around 50 °C to 300 °C at a depth of 1500 m. Most of western and part of the eastern Hokkaido are characterized by high temperature gradients, while low temperatures were found in the central region. Higher temperatures in shallower crust imply the western region and part of the eastern region have high geothermal potential. Moreover, several LST zones considered to have high geothermal potential were identified upon clarification of the underground heat distribution according to 3D SST. LST in these zones showed the anomalies, 3 to 9 °C higher than the surrounding areas. These results demonstrate that our combination of TIR and 3D temperature modeling using well logging and geostatistics is an efficient and promising approach to geothermal resource exploration.

Brucella infection in Hokkaido was serologically surveyed in four species of pinnipeds inhabiting Cape Erimo during 2008-2013 and the Shiretoko Peninsula in 1999 by ELISA using Brucella abortus and B. canis as antigens. Anti-Brucella positive sera showed higher absorbance to B. abortus than B. canis in almost all samples. Anti-B. abortus antibodies were detected in serum samples from 24% (n = 55) of Western Pacific harbor seals (Phoca vitulina stejnegeri) in Cape Erimo and from 66% (n = 41) of spotted seals (P. largha), 15% (n = 20) of ribbon seals (Histriophoca fasciata) and 18% (n = 17) of Western Steller's sea lions (Eumetopias jubatus jubatus) in the Shiretoko Peninsula. Anti-Brucella antibodies were detected at higher absorbance in 1- to 4-year-old harbor seals than in the pups and mature animals, suggesting either that Brucella infection mainly occurs after weaning or that it is maternally transmitted to pups with premature or suppressed immunity. Anti-Brucella antibodies were detected in both immature and mature spotted seals and ribbon seals, with higher absorbance in the former. The antibodies were detected only in mature Western Steller's sea lions. Western blot analysis of the serum samples showed some differences in band appearances, namely discrete versus smeary, and in the number of bands, indicating that multiple different Brucella may be prevalent in pinnipeds in Hokkaido. Alternatively, the Brucella of pinnipeds may have some intra-species diversity. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

Full Text Available Microcytosis is observed in healthy Japanese breed dogs. The aim of the study was to evaluate the frequency and intensity of asymptomatic anisocytosis using a three-grade scale in Japanese dog breeds with special emphasis on the following indices: mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, and red blood cell distribution width. The retrospective study included analyses of blood morphology and blood smear for clinically healthy Japanese dog breeds Shiba, Akita, and Hokkaido aged from 6 months to 14 years, performed as a part of preventative care. A total of 74 dogs of both sexes were qualified for the study. The group included both neutered and non-neutered animals (Akita – 17 females, 12 males, Shiba – 24 females, 18 males, Hokkaido – 2 females, 1 male. The blood smear revealed significant anisocytosis in 60.8% and mild anisocytosis in 28.4% of the tested dogs – 89.2% in total. Microcytosis was reported for 25.7% of the tested Japanese breed dogs. Reduced mean cell haemoglobin and mean cell haemoglobin concentration were diagnosed in 75.7% and 40.5% of dogs, respectively. Red blood cell distribution width as an anisocytosis indicator exceeded the norm in 12% of the tested dogs. Compared to mixed breed dogs, the Japanese breeds had a reduced mean cell volume, mean cell haemoglobin concentration and significant anisocytosis in the blood smear as well as a higher red blood cell distribution width indicator. Veterinarians should consider these differences when interpreting the results of morphological blood tests.

The red-crowned crane (Grus japonensis) from eastern Hokkaido is classified as a Special Natural Monument in Japan. In this study, we determined the concentrations of persistent organic pollutants (POPs) in red-crowned crane muscle tissues (n = 47). Polychlorinated biphenyls (PCBs) had the highest median concentration (240ng/g lipid weight), followed by dichlorodiphenyltrichloroethane and its metabolites (DDTs) (150ng/g lipid weight), chlordane-related compounds (CHLs) (36ng/g lipid weight), hexachlorobenzene (HCB) (16ng/g lipid weight), hexachlorocyclohexanes (HCHs) (4.4ng/g lipid weight), polybrominated diphenyl ethers (PBDEs) (1.8ng/g lipid weight), and finally, Mirex (1.5ng/g lipid weight). Additionally, a positive correlation was found among POP concentrations. No sex differences beyond body parameters were observed. Additionally, red-crowned cranes exhibited a high enantiomeric excess of (+)-alpha-HCH, with enantiomer fractions varying from 0.51 to 0.87 (average: 0.69). Copyright © 2017 Elsevier Inc.

Since herbivores like cattle and horse take plants contaminated by radioactive fallout, 90 Sr in their bones can be a excellent biological measure of environmental radioactive pollution. The authors continued and reported such investigations on 90 Sr accumulation from 1957 and this paper described the summary from 1987 to 1996. Samples of 225 cattle bones and 257 horse bones were treated at 900 deg C for 5-6 hr. 90 Y extracted by (2-ethylhexyl)phosphoric acid from the samples was measured in the low back-ground gas-flow counter and the concentrations (mBq/g·Ca) of the parent nuclide 90 Sr were estimated. Bone level of 90 Sr, after peaked at 1965-1966, had deceased thereafter and became the minimum at 1995 in the cattle and at 1996 in the horse. Horse bones contained the higher 90 Sr level than cattle's. There was a positive correlation between the age and 90 Sr concentration. In conclusion, the environmental radioactivity due to the fallout is low at present in Hokkaido. (K.H.)

To identify the unusual climate conditions and their connections to air pollutions in a remote area due to wildfires, we examine three anomalous large-scale wildfires in May 2003, April 2008, and July 2014 over East Eurasia, as well as how products of those wildfires reached an urban city, Sapporo, in the northern part of Japan (Hokkaido), significantly affecting the air quality. NASA's MERRA-2 (the Modern-Era Retrospective analysis for Research and Applications, Version 2) aerosol re-analysis data closely reproduced the PM 2.5 variations in Sapporo for the case of smoke arrival in July 2014. Results show that all three cases featured unusually early snowmelt in East Eurasia, accompanied by warmer and drier surface conditions in the months leading to the fires, inducing long-lasting soil dryness and producing climate and environmental conditions conducive to active wildfires. Due to prevailing anomalous synoptic-scale atmospheric motions, smoke from those fires eventually reached a remote area, Hokkaido, and worsened the air quality in Sapporo. In future studies, continuous monitoring of the timing of Eurasian snowmelt and the air quality from the source regions to remote regions, coupled with the analysis of atmospheric and surface conditions, may be essential in more accurately predicting the effects of wildfires on air quality.

Concentrations of 137 Cs, 134 Cs and potassium were measured in cultivated and wild mushrooms and their matrixes (soils or woods) collected from Hokkaido in 1990. The 137 Cs concentrations in mushrooms were in the range of 0.07-188.9Bq/kg fresh weight. The highest 137 Cs concentration was observed in Clitocybe clavipes. The 137 Cs concentration ratios of the wood rotting fungi and the actomycorrhizal fungi were 0.8-5.0 and 0.3-1.1, respectively. Both values of mushrooms were remarkably higher than that of leafvegetables (10 -2 ∼10 -3 ). The potassium concentrations in mushrooms were in the range of 0.08-0.63 %. 134 Cs released from the Chernobyl atomic power plant stationin 1986 was observed in only Clitocybe clavipes. (author)

The authors investigated radiocarbon age differences among charred woods and charred residues on the surface of potteries. Results of radiocarbon dates of URAHORO-type pottery adhesions showed ca. 7560-7987 14 C BP, and that of charcoals were ca. 7180 14 C BP and 7285 14 C BP. The age of charred residues on the inside surface of potteries show 300-800 yrs older than the 14 C age of the charred woods, which corresponded to the actual age of the archaeological site, respectively. It becomes a cause to have cooked the salmon by earthenware and I think that the marine reservoir effect occurred. (author)

An extensive study program has been carried out to estimate hydrogeological characteristics of deep underground in Japan. As a part of this program, groundwater flow analysis in Hokkaido and Northeast Japan were conducted. For the analyses of these area, hydrogeological models representing topography, geology, distribution of hydraulic conductivity were developed using available informations from open literature. By use of these models, steady state three-dimensional groundwater flow under a saturated/unsaturated condition was calculated by means of finite element method. The results are as follows: (1) Distribution of piezometric head corresponds with topography in the study area. (2) Piezometric head distribution is hydrostatic below E.L.-1000m in the study area. (3) Hydraulic gradient in the study area is less than 0.04 below E.L.-500m. (4) Difference of boundary conditions at the shore side of these models does not affect the results of the analyses.

The SuperDARN HOkkaido Pair of (HOP) radars, consisting of the Hokkaido East (2006-) and West (2014-) radars, are the SuperDARN radars located at the lowest geomagnetic latitude (36.5 degrees), and have been continuously measuring ionospheric convection at high to subauroral and middle latitudes with high temporal resolutions (Japan from 15 to 19 UT on March 17, 2015 and from 1900 to 2030 UT on December 20, 2015, identified using optical instruments such as all-sky CCD camera, wide field of view digital camera and meridian scanning photometer. Both events occurred during the main phase of the relatively large geomagnetic storms with minimum Dst of -223 nT and -170 nT respectively. The ionospheric convection at mid-latitude regions associated with the low-latitude auroral emission is characterized by (1) transient equatorward flows up to about 500 m/s in the initial phase of the emission (the geomagnetic field data at Paratunka, Far East Russia show corresponding negative excursions), and (2) sheared flow structure consisting of westward flow (about 500 m/s) equatorward of eastward flow (1000 m/s), with the equatorward boundary of auroral emission embedded in the westward flow region which expanded up to below 50 deg geomagnetic latitude. These observations imply that the electric field / convection distribution plays important roles in continuously generating the low latitude auroral emission. In particular the observation of the equatorward flow (dawn-dusk electric field) up to as low as about 50 deg geomagnetic latitude is the direct evidence for the presence of electric field to drive ring current particles into the plasmaspheric regions.

In the Horonobe area of northern Hokkaido, the Japan Atomic Energy Agency has been carrying out various hydrological observations to estimate the recharge rate. Subsurface earth temperature and soil moisture content have been observed at HGW-1 site (GL-0.7m to GL-2.3m, since 2005) and Hokushin Meteorological Station (GL-0.1m to GL-1.1m, since 2008). The results have revealed groundwater infiltration and recharge occurring throughout year, the shallow groundwater-infiltration velocity depending on the depth and the position of the Zero Flux Plane. For the estimation of boundary conditions in groundwater flow simulation, in this study, the shallow groundwater-flow system has been examined qualitatively on the basis of the variation of the subsurface earth temperature and the soil moisture content. In the future, it is necessary to quantitatively assess the shallow groundwater infiltration and recharge rate, the intermediate runoff, and the evapotranspiration based on the observed data of the weighing lysimeter, and the other measurement stations in the area.

For the effective implementation of the survey, an analysis was conducted into areas expected to be successfully developed for geothermal energy, and promising areas and prioritized survey areas were selected. Data then in existence were collected at the Doto district 1, Doto district 2, Toyoha-Niseko district, and the Iburi district and subjected to reanalysis, and a wide area geothermal system conceptual model was built. Using the model, development-promising areas were extracted, the amount of resources was assessed, and an optimum survey program was prepared. One promising area was selected in the Doto district 1, four in the Doto district 2, two in the Toyoha-Niseko district, and one in the Iburi district. As prioritized survey areas, Musadake was selected in the Doto district 1; Yoichidake, Yunosawa, and Takinosawa in the Toyoha-Niseko district; and Raibadake in the Iburi district. A Monte Carlo analysis was conducted, and the result indicated that Musakake had 93-121MWe in resources of which 55MWe would be exploitable with a probability of not less than 90%. (NEDO)

With an objective of converting dairy farming wastes and fisheries wastes into resources to be used as energies, this paper discusses development trends and utilization possibilities thereof based on their utilization characteristics. The Tokachi, Abashiri and Nemuro regions produce more cattle wastes, and regions on the coast of the Sea of Okhotsk produce more hepatopancreas of scallop than other regions. The amount of energy from such wastes is subject to large seasonal variations. Methane gas production through methane fermentation is an effective treatment technology, although it is utilized less effectively in Hokkaido. Important is applying the processes depending on energy demand, supply characteristics and regional features. Taking waste utilization characteristics and regionally uneven distribution of resources into account, conceptions on six model systems that could be introduced were structured. The six systems include two types for fisheries wastes utilization, three types for agricultural and dairy farming wastes, and one type for combined utilization of agricultural and fishery wastes. Important factors to select suitable commercial operation sites and promote the operations are stable quantity assurance of waste resources, energy demand, and stable operation, such as could be available in fishery processing complexes and large dairy farming areas. 44 refs., 66 figs., 29 tabs.

Full Text Available During the past decades, national governments and international institutions have both searched for ways to equalise disparities and revitalise lagging regions. Although ideas and examples of the most effective ways to achieve these goals originate in various places, their influence is inclined to permeate elsewhere. Therefore, the processes involved in policy transfers are highly relevant from the perspective of regional development. This study approaches these processes through the case study of post-war Hokkaido and pays special attention to the role of three international development strategies: the Tennessee Valley Authority model, the Growth Pole Theory and the Industrial Cluster Theory. As a result, this research shows the wide variety of agents involved in policy transfer, analyses the processes of incorporating exogenous ideas into regional development polices and demonstrates the variety of sources from which different agents can draw lessons.

Recent introduction of H5N1 highly pathogenic avian influenza virus (HPAIV) in wild birds from poultry in Eurasia signaled the possibility that this virus may perpetuate in nature. Surveillance of avian influenza especially in migratory birds, therefore, has been conducted to provide information on the viruses brought by them to Hokkaido, Japan, from their nesting lakes in Siberia in autumn. During 2008-2009, 62 influenza viruses of 21 different combinations of hemagglutinin (HA) and neuraminidase (NA) subtypes were isolated. Up to September 2010, no HPAIV has been found, indicating that H5N1 HPAIV has not perpetuated at least dominantly in the lakes where ducks nest in summer in Siberia. The PB2 genes of 54 influenza viruses out of 283 influenza viruses isolated in Hokkaido in 2000-2009 were phylogenetically analysed. None of the genes showed close relation to those of H5N1 HPAIVs that were detected in wild birds found dead in Eurasia on the way back to their northern territory in spring.

We have been providing oral care for patients with head and neck cancer in Hokkaido University Hospital since 2007. In this paper, we report clinical statistics of the 254 head and neck cancer patients who received oral care. About 80 percent of these patients were treated with radiation therapy, so it is important to cope with adverse events related to such therapy. Oral care is helpful for cancer patients when it is started as soon as possible (at least 1 week before radiation therapy is started). The percentage of patients who could start oral care 4 days before radiation therapy gradually increased to about 60 percent by fiscal 2009. In fiscal 2010, the percentage decreased to its lowest level of 37.9 percent. To start oral care for all patients 7 days before irradiation, we are going to change our system and start oral care in the outpatient period. In their hometowns, oral care was continued for only 19 (27.0 percent) of the 74 patients who could not visit our hospital. An important task for our project is to establish a medical cooperation system for discharged patients treated for head and neck cancer. (author)

Perfluoroalkyl substances (PFAS) are persistent bio-accumulative chemicals that impact the health of pregnant women and their children. PFAS derive from environmental and consumer products, which depend on human lifestyle, socioeconomic characteristics, and time variation. Here, we aimed to explore the temporal trends of PFAS in pregnant women and the characteristics related to maternal PFAS concentration. Our study is part of the Hokkaido Study on Environment and Children's Health, the Hokkaido large-scale cohort that recruited pregnant women between 2003 and 2011. Blood samples were acquired from pregnant women during the third trimester to measure PFAS and cotinine concentrations. Maternal basic information was collected with a baseline structured questionnaire. Eleven PFAS were measured from 2123 samples with ultra-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry. Eight PFAS were above 80% detection rate and were included in the final analysis. We used multivariable linear regression to analyze the association of pregnant women characteristics with the levels of eight PFAS. The temporal trend of PFAS was observed in two periods (August 2003 to January 2006 and February 2006 to July 2012). The concentration of perfluorooctane sulfonate (PFOS) significantly decreased from August 2003 to January 2006 and from February 2006 to July 2012. The concentrations of perfluorododecanoic acid (PFDoDA), perfluoroundecanoic acid (PFUnDA), and perfluorotridecanoic acid (PFTrDA) increased significantly between August 2003 and January 2006, whereas they decreased significantly between February 2006 and July 2012. Women with pre-pregnancy body mass index (BMI) >25 kg/m² had lower PFUnDA, PFDoDA, and PFTrDA levels than did those with normal BMI (18.5⁻24.9 kg/m²). Pregnant women, who were active smokers (cotinine > 11.49 ng/mL), had higher PFOS than the non-smokers (cotinine PFAS levels and annual income or maternal education. PFAS

Full Text Available Abstract Background Infection with H5N1 highly pathogenic avian influenza viruses (HPAIVs of domestic poultry and wild birds has spread to more than 60 countries in Eurasia and Africa. It is concerned that HPAIVs may be perpetuated in the lakes in Siberia where migratory water birds nest in summer. To monitor whether HPAIVs circulate in migratory water birds, intensive surveillance of avian influenza has been performed in Mongolia and Japan in autumn each year. Until 2008, there had not been any H5N1 viruses isolated from migratory water birds that flew from their nesting lakes in Siberia. In autumn 2009, A/mallard/Hokkaido/24/09 (H5N1 (Mal/Hok/24/09 was isolated from a fecal sample of a mallard (Anas platyrhynchos that flew from Siberia to Hokkaido, Japan. The isolate was assessed for pathogenicity in chickens, domestic ducks, and quails and analyzed antigenically and phylogenetically. Results No clinical signs were observed in chickens inoculated intravenously with Mal/Hok/24/09 (H5N1. There was no viral replication in chickens inoculated intranasally with the isolate. None of the domestic ducks and quails inoculated intranasally with the isolate showed any clinical signs. There were no multiple basic amino acid residues at the cleavage site of the hemagglutinin (HA of the isolate. Each gene of Mal/Hok/24/09 (H5N1 is phylogenetically closely related to that of influenza viruses isolated from migratory water birds that flew from their nesting lakes in autumn. Additionally, the antigenicity of the HA of the isolate was similar to that of the viruses isolated from migratory water birds in Hokkaido that flew from their northern territory in autumn and different from those of HPAIVs isolated from birds found dead in China, Mongolia, and Japan on the way back to their northern territory in spring. Conclusion Mal/Hok/24/09 (H5N1 is a non-pathogenic avian influenza virus for chickens, domestic ducks, and quails, and is antigenically and genetically

Disturbances in VHF/UHF telemetry links as a possible effect of the 2003 Hokkaido Tokachi-oki earthquake

Directory of Open Access Journals (Sweden)

H. Nagamoto

2008-08-01

Full Text Available The data on radio telemetry links (for water information at VHF/UHF in Hokkaido are used to investigate the rate of disturbances on radio links (or connection failure and its association with a huge earthquake, Tokachi-oki earthquake on 26 September 2003. Especially, the telemetry links at the Tokachi region closest to the earthquake epicenter, showed a significant increase in disturbances on radio links two weeks to a few days before the earthquake on the basis of analysis during a long interval from 1 June 2002 to 3 November 2007 (over 5 years. We suggest that these severe disturbances in VHF/UHF telemetry links are attributed to the generation of seismogenic VHF/UHF radio noises (emissions. Based on this idea, we have estimated that the intensity of these seismogenic emissions is on the order of 10–19 dB μV/m. Finally, the present result was compared with other physical parameters already obtained for this earthquake.

In order to assess the long-term stability of the geological environments for over several hundred thousand years, it is important to consider the influence of natural events and processes, such as uplift, subsidence, denudation and climate change, on the geological environments, especially in an active region such as Japan. This study presents a conceptual model related to the future natural events and processes which have potential impacts on the groundwater flow conditions in the Horonobe area, Hokkaido, northern Japan on the basis of the neo-tectonics, palaeogeography, palaeo-climate, historical development of landform, and present state of groundwater flow conditions. We conclude that it is important to consider interactions among natural events and processes on the describing of the best-possible approximation of the time-variation of geological environment.

Measles is an acute and highly contagious disease caused by measles virus (MeV). The government of Japan, following the last epidemic in 2007 and 2008, which was caused by genotype D5 strains, introduced a catch-up-vaccination program for teenagers during Japan fiscal years 2008-2012 and a mandatory case-based reporting system for the nationwide elimination. Furthermore, laboratory confirmation of measles cases by genotyping of isolates has been performed to clarify the source of infection and support the interruption of measles cases. Owing to these preventive measures, the number of measles cases has been steadily decreasing after the last epidemic. In March 2015, Japan was internationally verified as having achieved measles elimination by the World Health Organization Regional Office for the Western Pacific. The continuous elimination of measles and high levels of vaccination coverage for MeV have been maintained nationally. However, imported or import-associated cases of measles have sporadically occurred during this time. After the last nationwide epidemic, 17 imported or import-associated measles cases (MeV strains identified as genotypes H1, D4, D8, and B3) were reported in Hokkaido, the northern islands of Japan. In this study, we present the occurrence of measles and surveillance activities in Hokkaido during 2006-2015.

District heating has been used in Switzerland for more than 50 years. Its share of the heat market is less than 3% today. An analysis of the use of district heating in various European countries shows that a high share of district heating in the heat market is always dependent on ideal conditions for its use. Market prospects and possible future developments in the use of district heating in Switzerland are described in this paper. The main Swiss producers and distributors of district heating are members of the Association of District Heating Producers and Distributors. This association supports the installation of district heating facilities where ecological, energetical and economic aspects indicate that district heating would be a good solution.

Larch forests are distributed extensively in the east Eurasian continent and are expected to play a significant role in the terrestrial ecosystem carbon cycling process. In view of the fact that studies on carbon exchange for this important biome have been very limited, we have initiated a long-term flux observation in a larch forest ecosystem in Hokkaido in northern Japan since 2000. The net ecosystem CO 2 exchange (NEE) showed large seasonal and diurnal variation. Generally, the larch forest ecosystem released CO 2 in nighttime and assimilated CO 2 in daytime during the growing season from May to October. The ecosystem started to become a net carbon sink in May, reaching a maximum carbon uptake as high as 186 g C m -2 month -1 in June. With the yellowing, senescing and leaf fall, the ecosystem turned into a carbon source in November. During the non-growing season, the larch forest ecosystem became a net source of CO 2 , releasing an average of 16.7 g C m -2 month -1 . Overall, the ecosystem sequestered 141-240 g C m -2 yr -1 in 2001. The NEE was significantly influenced by environmental factors. Respiration of the ecosystem, for example, was exponentially dependent on air temperature, while photosynthesis was related to the incident PAR in a manner consistent with the Michaelis-Menten model. Although the vapor pressure deficit (VPD) was scarcely higher than 15 hPa, the CO 2 uptake rate was also depressed when VPD surpassed 10 hPa (Author)

Rb-Sr geochronological study on Tatehira granodiorite, Oshima Peninsula, Southwest Hokkaido, Japan

It has been known that Tatehira granodiorite, a pluton which occurs sporadically in the southwest region of Hokkaido, is related with Kanoite formation. The radiometric age of this granodiorite still remains unknown. The Tatehira granodiorite intrudes into late Paleozoic or early Mesozoic Matsumae group, and is overlain by Miocene Usubetsu formation unconformably. It occurs as several separated small plutons. The samples for Rb-Sr analysis were collected from one of the plutons in southern part. The determination of the isochron age of rock-minerals and the initial Sr isotopic ratio of Tatehira granodiorite were carried out. This granodiorite is able to be classified into two phases, namely melanocratic (WRM) and leucocratic (WRL) phases. The samples of WRM and WRL were powdered and subjected to X-ray analysis. It was found that the chemical compositions were similar except slight differences in FeO + Fe2O3, CaO and K2O. The Sr isotopic ratio was determined with a MAT 261 mass spectrometer, and the results were analyzed statistically. The Rb and Sr concentrations and the Sr isotopic ratio of WRM, WRL, and PRF (plagio-clase rich fraction) and BRF (biotite rich fraction) separated from the WRL were determined, and the age of 102.5 +- 0.3 Ma and the initial ratio of 0.70538 +- 0.00001 were obtained. The ratio of Tatehira granodiorite is comparable to that of Okushiri Island. Comparing with the data obtained from other region, the granodiorites of Tatehira and Okushiri Island should be related with the granitoids of Abukuma granite province.

Full Text Available Results of simultaneous LF subionospheric monitoring over two different propagation paths prior to the very strong Tokachi earthquake (near the east coast of Hokkaido Island, 25 September 2003 of magnitude 8.3 are presented firstly. Nighttime amplitude fluctuations of the Japanese Time Standard Transmitter (JG2AS, 40kHz signal received at Moshiri (Japan, 142°E, 44°N and at Petropavlovsk-Kamchatski (Russia, 158°E, 53°N were analyzed. As a possible precursory signature we observed synchronous intensification of quasi periodical 16-day variations of the dispersion in the signals received at both observation stations before the earthquake. The strongest deviations observed as a rule were depletions of signal amplitude probably connected with increase of loss in the ionosphere by the enhancement of turbulence. This is due to dissipation of internal gravity waves (IGW at the lower ionosphere heights. A scheme for seismo-IGW-planetary waves (PW interconnection has been justified to explain the observed connection with strong earthquakes. It considers the seasonal variability in the signal.

The influence of Hokkaido pumpkin powder (PP) addition to corn grits at levels 4%, 6%, and 8% and ascorbic acid (AA) addition at levels 0.5% and 1% was evaluated. Extrusion was done using a single-screw extruder at two temperature regimes: 135/170/170°C (E1) and 100/150/150°C (E2). Mathematical models that describe the influence of additives on the colour of extrudates were determined. Raw extrusion mixtures as well as obtained extrudates were tested for ascorbic acid, polyphenol, proteins, fat, crude fibre, ash and carotenoids content, and antioxidant activity. E1 extrusion regime acted favourably on polyphenols, crude fibre content, and antioxidant activity. It also caused higher fat degradation than E2 extrusion. Xanthophylls (lutein and zeaxanthin) were less sensitive to extrusion than carotenes (α-carotene, 9-cis-β-carotene and 13-cis-β-carotene). Ascorbic acid was more sensitive to higher extrusion temperatures (49-76% degradation). It provided protection to carotenoids and consequently the colour of the extrudates.

We investigated the geological structure and hydrogeological properties of the Omagari Fault in Neogene siliceous sedimentary rocks of the Horonobe area, northern Hokkaido, by geological mapping, borehole investigations, reflection seismic survey, and audio-frequency magnetotelluric survey. As a result of the investigation, the 3-D distribution of the Fault was clarified and the following were shown. In addition, the magnetotelluric survey in particular was effective for mapping of the 3-D distribution and hydrogeological properties of the fault. The Omagari Fault has a fault zone, about 120 m wide, that consists mainly of the damage zone, and has a permeable structure. The magnetotelluric survey shows several high-resistivity zones, one of which corresponds to the Omagari Fault inferred from the reflection seismic surveys. The high resistivity zones are correlative with the concentration zones of low-saline water, which suggests infiltration of ground water through the permeable Omagari Fault zone. The Omagari Fault over-steps at the earth surface and at the same time is converging in subsurface zones. (author)

2004-03-01

The morphological characteristics of myoepithelial cells and arrectores pilorum muscles were investigated in caudal, metatarsal and preorbital glands of Hokkaido sika deer (Cervus nippon yesoensis Heude, 1884) using immunohistochemistry for alpha-smooth muscle actin. In the metatarsal, preorbital and general skin glands, myoepithelial cell layers continuously embraced the secretory epithelium, while in the caudal gland, discontinuous myoepithelial cell rows surrounded the apocrine tubules. There was a trend that the widths of the myoepithelial cells of the caudal and preorbital glands appeared to be thinner than those of the metatarsal and general skin glands. In the metatarsal gland, the arrectores pilorum muscles were highly developed and considerably larger than those in other skin glands.

Iizumi, Shigeru; Kobayashi, Hideo; Toyoda, Minoru.

1984-01-01

It has been known that Tatehira granodiorite, a pluton which occurs sporadically in the southwest region of Hokkaido, is related with Kanoite formation. The radiometric age of this granodiorite still remains unknown. The Tatehira granodiorite intrudes into late Paleozoic or early Mesozoic Matsumae group, and is overlain by Miocene Usubetsu formation unconformably. It occurs as several separated small plutons. The samples for Rb-Sr analysis were collected from one of the plutons in southern part. The determination of the isochron age of rock-minerals and the initial Sr isotopic ratio of Tatehira granodiorite were carried out. This granodiorite is able to be classified into two phases, namely melanocratic (WRM) and leucocratic (WRL) phases. The samples of WRM and WRL were powdered and subjected to X-ray analysis. It was found that the chemical compositions were similar except slight differences in FeO + Fe 2 O 3 , CaO and K 2 O. The Sr isotopic ratio was determined with a MAT 261 mass spectrometer, and the results were analyzed statistically. The Rb and Sr concentrations and the Sr isotopic ratio of WRM, WRL, and PRF (plagio-clase rich fraction) and BRF (biotite rich fraction) separated from the WRL were determined, and the age of 102.5 +- 0.3 Ma and the initial ratio of 0.70538 +- 0.00001 were obtained. The ratio of Tatehira granodiorite is comparable to that of Okushiri Island. Comparing with the data obtained from other region, the granodiorites of Tatehira and Okushiri Island should be related with the granitoids of Abukuma granite province. (Ishimitsu, A.)

Development of hot water supply system for a small district heating reactor

International Nuclear Information System (INIS)

Murase, Toshihiko; Narabayashi, Tadashi; Shimazu, Yoichiro

2007-01-01

On the earth, there are many environmental problems. For example, rapid increase of world population causes the enormous consumption of fossil fuel and emission of CO 2 into the global air. Now, mankaind faced to deal with these serious problems. One solution for these problems is utilization of nuclear reactors. Currently, about 65% of thermal output of a nuclear reactor is thrown away to the sea or the atmosphere through a turbine condenser. When a hot-water pipeline from a nuclear plant will be constructed, the exhaust heat from nuclear reactor will able to be utilized. Therefore, authors began to study nuclear power plant system for district heating. This reactor is based on a PWR plant. Its thermal output is 10 MWth and its electrical output is 3.4 MW. The nuclear plant supply electricity and heat for 2000 to 3000 houses. The plant aim to supply all the energy for the adjacent pepole's life, for example, heat, electricity and hydrogen for fuel battery car. This total-energy supply system assumed to be built in Northern area such as Hokkaido in Japan. In order to develop an optimum thermal design method for the system, heat transport experiments and thermal-hydraulic calculations were carried out. Using a metal pipe covered with foam-polyurethane thermal insulator, feed-water temperature and return-water temperature was measured to evaluate heat loss. As the result, the heat loss from the hot-water temperature was very little. The thermal-hydraulic calculation method was verified and applied to actual pipeline size calculation. The result of heat loss calculation will be 0.2degC/5 km. considering these results, the best pipe specification was obtained. (author)

To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

Tokiwa, Tetsuya; Niizato, Tadafumi; Nohara, Tsuyoshi; Asamori, Koichi; Matsuura, Yuki; Kosaka, Hideki

2011-01-01

In this study, we present the preliminary results for the estimation of a horizontal crustal movement by using geodetic and geological approach in the Horonobe area, northern Hokkaido, Japan. The estimations have been carried out by using a GPS data and a geological cross section obtained by applying balanced-section method. As results of this study, both of the shortening rates estimated by GPS data and balanced-section method indicate several millimeters per year. Namely, there is no contradiction between geodetic and geological data, and it is considered that Horonobe area is still situated similar tendency and magnitude of a crustal movement. It is seemingly considered that geodetic data is unhelpful for estimating the long-term crustal movement, because period of geodetic observations is a very short. However, the result of this study indicates that geodetic data provide valuable information for estimating the long-term crustal movement in the area, and it is considered that geodetic approach play an important role in improvement of the credibility of evaluation for prediction of long-term stability.

Formation processes of the 1909 Tarumai and the 1944 Usu lava domesin Hokkaido, Japan

Directory of Open Access Journals (Sweden)

I. Yokoyama

2004-06-01

Full Text Available The formation of the two particular lava domes in Hokkaido, Japan is described and interpreted mainly from geophysical viewpoints. The 1909 eruption of Tarumai volcano was not violent but produced a lava dome over four days. The growth rate of the dome is discussed under the assumption that the lava flow was viscous and plastic fluid during its effusion. By Hagen-Poiseuille?s Law, the length of the conduit of the lava dome is rather ambiguously determined as a function of viscosity of the magma and diameter of the conduit. The 1944 Usu dome extruded as a parasitic cone of Usu volcano, not in the crater, but in a flat cornfield at the foot of the volcano. From the beginning to the end for more than 17 months, seismometric and geodetic observations of the dome activity were carried out by several pioneering geophysicists. Utilizing their data, pseudo growth curves of the dome at each stage can be drawn. The lava ascended rather uniformly, causing uplift of the ground surface until half-solidified lava reached the surface six months after the deformation began. Thereafter, the lava dome added lateral displacements and finally achieved its onion structure. These two lava domes are of contrasting character, one is andesitic and formed quickly while the other is dacitic and formed slowly, but both of them behaved as viscous and plastic flows during effusion. It is concluded that both the lava domes formed by uplift of magma forced to flow through the conduits, analogous to squeezing toothpaste out of a tube.

Future Services for District Heating Solutions in Residential Districts

Directory of Open Access Journals (Sweden)

Hannele Ahvenniemi

2014-06-01

Full Text Available The underlying assumption of this study is that in order to retain the competitiveness while reaching for the EU targets regarding low-energy construction, district heating companies need to develop new business and service models. How district heating companies could broaden their perspective and switch to a more service-oriented way of thinking is a key interest of our research. The used methods in our study are house builder interviews and a questionnaire. With the help of these methods we discussed the potential interest in heating related services acquiring a comprehensive understanding of the customer needs. The results indicate the importance of certain criteria when choosing the heating system in households: easiness, comfort and affordability seem to dominate the house builders’ preferences. Also environmental awareness seems to be for many an important factor when making a decision about the heating of the house. Altogether, based on the results of this study, we suggest that the prospects of district heating could benefit from highlighting certain aspects and strengths in the future. District heating companies need to increase flexibility, readiness to adopt new services, to invest in new marketing strategies and improving the communication skills.

Prevention of alveolar echinococcosis--ecosystem and risk management perspectives in Japan.

Science.gov (United States)

Konno, Keita; Oku, Yuzaburo; Tamashiro, Hiko

2003-12-01

We focused on the epidemiology of alveolar echinococcosis especially in Japan and discussed control measures to prevent an epidemic. No effective control measures against alveolar echinococcosis have been identified thus far because it is difficult to fully understand the ecology of the parasite and its hosts, i.e. the precise infection route to humans. In Hokkaido, Japan, infection rates among red foxes have recently risen even in low endemic districts. Infection seems to be spreading not only among wild foxes but also among domestic dogs. Despite only sporadic reports of human cases in Japan, we predict that the incidence of alveolar echinococcosis will increase in the near future if no effective preventive measures are put in place. An Echinococcus multilocularis epidemic would have the potential to affect the economy of Hokkaido, due to its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are, therefore, urgently required prior to large outbreaks, based on understanding of the ecosystem around E. multilocularis.

District Energy Windsor

Energy Technology Data Exchange (ETDEWEB)

NONE

2002-07-01

This paper presents a summary of how District Energy Windsor operates. It includes a system site map and reasons why it is advantageous to get connected to a district heating system. District Energy Windsor is a division of the Windsor Utilities Commission. It was developed in 1996 and was the first in North America to supply both heating and cooling requirements. It supplies nearly 2 million square feet of heating and cooling for Windsor's city centre. The district energy system produces hot water or chilled water at a central plant. Energy is then piped out to buildings in the area, including the Art Gallery of Windsor, the Royal Bank Business Centre, the Windsor Justice Facility, the Windsor Casino, and Northwind Windsor. The energy, which is transferred through heat exchangers, is used for space heating, domestic hot water heating, and air conditioning. The 8 reasons for getting connected are: (1) less management costs, (2) lower energy costs, (3) lower level of risk management, (4) stable energy rates, (5) better use of building space, (6) reliable service, (7) reduced expansion costs, and (8) a cleaner environment. District heating improves air quality through reduced carbon dioxide and nitrogen oxide emissions. In addition, fuel delivery and storage are eliminated. figs.

Intra-District Disparities in Primary Education: A Case Study of Bankura District, West Bengal

Directory of Open Access Journals (Sweden)

Krishnendu Maji

2017-03-01

Full Text Available The level of education and its response to different educational opportunities vary from one spatial unit to another depending on various factors like social, economic, cultural, and institutional. It is understood that certain regions acquire relative advancements over others in terms of human resource development and human capital formation. The key purpose of this research is to examine the intra-district disparities in primary education in Bankura District one of the districts of West Bengal. It ranks 11thamong the 19 districts of West Bengal (Human Development Report, 2007.  Overall literacy rate of the district stands at 70.26% but the district scores low in terms of female literacy rates, which is 60.05%,whereas the male literacy rate is 80.05%, which is a huge gender literacy gap of 20%. There are also regional inequalities existing at block level. Kotulpur ranks first with a literacy rate of 78.01% while Saltora occupies the bottom position with literacy rate of just 61.45% (Census of India, 2011. The level of educational development is dependent on several factors—enrolment ratio, dropout and repetition rates, pupil-teacher ratio, habitations covered by educational institutions, space-student ratio, drinking water and sanitation facilities in school, etc. In this context, the present study aims at examining the issues of intra-district disparities in educational attainment with regard to various educational amenities of Bankura district, West Bengal. Ten attributes have been selected to examine the level of development in primary education. It is clear from the study that the level of development in eastern part of the district is relatively better in comparison to other regions. Economic backwardness and physical bottlenecks continue to be major issues in western blocks.

2018-06-07

State agencies play a critical role in providing school districts with guidance and technical assistance on school nutrition issues, including food and beverage marketing practices. We examined associations between state-level guidance and the policies and practices in school districts regarding food and beverage marketing and promotion. State policy guidance was positively associated with districts prohibiting advertisements for junk food or fast food restaurants on school property. Technical assistance from states was negatively associated with 2 district practices to restrict marketing of unhealthy foods and beverages, but positively associated with 1 practice to promote healthy options. These findings may help inform the guidance that states provide to school districts and help identify which districts may need additional assistance to address marketing and promotion practices.

2015-12-01

A previously undescribed Anaplasma species (herein referred to as AP-sd) has been detected in sika deer, cattle and ticks in Japan. Despite being highly similar to some strains of A. phagocytophilum, AP-sd has never been detected in humans. Its ambiguous epidemiology and the lack of tools for its specific detection make it difficult to understand and interpret the prevalence of this Anaplasma species. We developed a method for specific detection, and examined AP-sd prevalence in Hokkaido wildlife. Our study included 250 sika deer (Cervus nippon yesoensis), 13 brown bears (Ursus arctos yesoensis) and 252 rodents including 138 (Apodemus speciosus), 45 (Apodemus argenteus), 42 (Myodes rufocanus) and 27 (Myodes rutilus) were collected from Hokkaido island, northern Japan, collected during 2010 to 2015. A 770 bp and 382 bp segment of the 16S rRNA and gltA genes, respectively, were amplified by nested PCR. Results were confirmed by cloning and sequencing of the positive PCR products. A reverse line blot hybridization (RLB) based on the 16S rRNA gene was then developed for the specific detection of AP-sd. The prevalence of AP-sd by nested PCR in sika deer was 51% (128/250). We detected this Anaplasma sp. for the first time in wild brown bears and rodents with a prevalence of 15% (2/13) and 2.4% (6/252), respectively. The sequencing results of the 16S rRNA and gltA gene amplicons were divergent from the selected A. phagocytophilum sequences in GenBank. Using a newly designed AP-sd specific probe for RLB has enabled us to specifically detect this Anaplasma species. Besides sika deer and cattle, wild brown bears and rodents were identified as potential reservoir hosts for AP-sd. This study provided a high throughput molecular method that specifically detects AP-sd, and which can be used to investigate its ecology and its potential as a threat to humans in Japan.

Takao Kameda

2002-07-01

Full Text Available Deep ice coring to bedrock (3028m in depth at Dome Fuji Station is planned during three successive summer seasons starting from 2003/2004. An improved JARE deep ice core drill (12.2m in length and 3.8m in maximum core length was developed in December 2001 for the ice coring at Dome Fuji. In January/February of 2002,we performed experiments on drill performance using artificial ice blocks in Rikubetsu, Hokkaido. In this paper, we outline the experiment and report the results. It was found through the experiment that an ice core of 3.8m length was smoothly obtained by the improved drill with three screws in the chip chamber and cutting pitch of 5mm/cycle. About 45000 small holes 1.2mm in diameter were made on the surface of the chip chamber. These small holes enabled liquid to circulate between cutters and outside of the drill through the chip chamber in the drill. The dry density of the chips was 440 to 500kg/m^3 and the chip recovery rate during ice coring was 65 to 91%. A check valve installed at the bottom of the chip chamber to prevent outflow of chips from the drill was not tested enough, but more durability is needed for the valve. The newly developed motor system and core catchers of the drill worked perfectly. The average coring speed was 24.5cm/min with cutting pitch of 5mm/cycle. The average power consumption during ice coring was 171W.

Reinstating district nursing: A UK perspective.

Science.gov (United States)

Morris, Hannah

2017-09-01

As policy directives gather pace for service provision to be delivered in primary care, district nursing has not been recognised as a valuable asset to facilitate this agenda. Investment in district nursing and specialist district nursing education has fallen. This is concurrent with an ageing district nursing workforce, a lack of recruitment and growing caseloads, as district nursing adapts to meet the challenges of the complexities of contemporary healthcare in the community. The district nurse role is complex and multifaceted and includes working collaboratively and creatively to coordinate care. Redressing the shortages of specialist district nurse practitioners with increased numbers of health care support workers will not replace the skill, knowledge, experience required to meet the complex care needs of today's society. District nursing needs to be reinstated as the valuable asset it is, through renewed investment in the service, research development and in specialist practice education. To prevent extinction district nurses need to be able to demonstrate and articulate the complexities and dynamisms of the role to reinstate themselves to their commissioners as a valuable asset for contemporary practice that can meet current health and social care needs effectively.

This analysis of combined data from the NAEP and the Common Core of Data (CCD was intended to address the issue. We analyzed 1990, 1992, and 1996 NAEP 8th grade mathematics national assessment data in combination with CCD data of corresponding years to examine the extent to which student achievement was related to districts' control over instructional expenditure, adjusting for relevant key factors at both district and student levels. Upon sample modification, we used hierarchical linear modeling (HLM to estimate the relationships of student achievement to two district fiscal policy indictors, current expenditure per pupil (CEPP and districts' discretionary rates for instructional expenditure (DDR. Net of relevant district factors, DDR was found unrelated to districts' average 8th grade math performance. The null effect was consistent in the analysis of the combined NAEP-CCD data for 1990, 1992, and 1996. In contrast, CEPP was found related to higher math performance in a modest yet fairly consistent way. Future research may be productive to separately study individual states and integrate the findings onto the national level.

Characteristics of uranium districts of the Russian Federation

International Nuclear Information System (INIS)

Boitsov, A.V.; Nikolsky, A.L.

2001-01-01

Uranium deposits are discovered in 15 ore districts of the Russian Federation. They are subdivided into four groups: Streltsovsky district with existing production centre, Stavropolsky district with depleted deposits, three prospective districts and ten reserve districts. The overview of new data on these districts is presented. Streltsovsky district with Priargunsky Production Centre include 19 molybdenum-uranium deposits of structure-bound volcanic type in caldera. The main activities in Stavropolsky district with two depleted uranium deposits are connected with restoration works and wastes rehabilitation. Except Streltsovsky district there are no more deposits in the Russian Federation prepared for uranium production. At the same time some uranium deposits of Vitimsky, Zauralsky, and West-Siberian districts are prospective for new development of production centres. They belong to the sandstone type, related to paleovalley or basal channel, and are suitable for ISL operation. The deposits of the other districts are considered to be reserve and considered unprofitable for uranium production at present and in the nearest future. The biggest of them is Aldansky district with gold-uranium deposits in potassium metasomatites in areas of Mesozoic activation of Archean cratons. Central Transbaikalsky, Yeniseisky, Yergeninsky, Onezhsky, Ladozhsky, Bureinsky, Khankaisky, Volgo-Uralsky reserve districts include mainly small-size deposits of vein, volcanic, surficial and metasomatite types with low uranium grades.

ABSTRACT Background: Poor quality of care and access to effective and affordable interventions have been attributed to constraints and bottlenecks within and outside the health system. However, there is limited understanding of health system barriers to utilization and delivery of appropriate, high-impact, and cost-effective interventions at the point of service delivery in districts and sub-districts in low-income countries. In this study we illustrate the use of the bottleneck analysis approach, which could be used to identify bottlenecks in service delivery within the district health system. Methods: A modified Tanahashi model with six determinants for effective coverage was used to determine bottlenecks in service provision for maternal and newborn care. The following interventions provided during antenatal care were used as tracer interventions: use of iron and folic acid, intermittent presumptive treatment for malaria, HIV counseling and testing, and syphilis testing. Data from cross-sectional household and health facility surveys in Mayuge and Namayingo districts in Uganda were used in this study. Results: Effective coverage and human resource gaps were identified as the biggest bottlenecks in both districts, with coverage ranging from 0% to 66% for effective coverage and from 46% to 58% for availability of health facility staff. Our findings revealed a similar pattern in bottlenecks in both districts for particular interventions although the districts are functionally independent. Conclusion: The modified Tanahashi model is an analysis tool that can be used to identify bottlenecks to effective coverage within the district health system, for instance, the effective coverage for maternal and newborn care interventions. However, the analysis is highly dependent on the availability of data to populate all six determinants and could benefit from further validation analysis for the causes of bottlenecks identified.

[How can we prevent alveolar echinococcosis? Ecosystem and risk management viewpoints].

Science.gov (United States)

Konno, Keita; Oku, Yuzaburo; Kamiya, Masao; Doi, Rikuo; Tamashiro, Hidehiko

2002-01-01

This article focuses on understanding epidemiological features of alveolar echinococcosis and discussing its prevention and control, especially from a viewpoint of the ecosystem and risk management. Publications on alveolar echinococcosis throughout the world were systematically reviewed with special reference to ecology, epidemiology and countermeasures. Alveolar echinococcosis, caused by accidental infection with larva of the parasite Echinococcus multilocularis is fatal to humans unless diagnosed at an early stage. No effective control measures have been identified so far because it is difficult to fully understand the ecology of the parasite and its intermediate and definitive hosts. It is also not easy to determine the precise infection route to humans mainly because of the long latent period. In Hokkaido, infection rates among red foxes have recently risen even in low endemic districts. Not only stray and domestic dogs but also some pigs in Hokkaido have been found to be infected. While the number of reported human cases is still small, around 10 cases per year, local residents seem to be threatened with the risk of infection. We predict that the incidence of alveolar echinococcosis among humans in Japan will increase in the near future if no effective preventive measures are conducted. In addition, Echinococcus multilocularis infection has the potential to affect the economy of Hokkaido because of its impact on the agricultural and tourist industries. Well-designed epidemiological surveys are therefore urgently required, in the context of ecosystem and risk management prior to large outbreaks. International collaboration is also desired.

2014-03-01

To explore the prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) in veterinary medical practices, MRSA carriage was tested among 96 veterinarians (Vets), 70 veterinary technicians (VTs) and 292 dogs with which they had contact at 71 private veterinary clinics (VCs) in Hokkaido, Japan. MRSA isolates were obtained from 22 Vets [22.9%] and 7 VTs [10%]. The prevalence of MRSA among Vets was as high as that found in an academic veterinary hospital in our previous study. In contrast, only two blood donor dogs and one dog with liver disease (1.0%, 3/292) yielded MRSA. All MRSA-positive dogs were reared or treated in different VCs, in each of which at least one veterinary staff member carrying MRSA worked. Sequence types (ST) identified by multilocus sequence typing, spa types, and SCCmec types for canine MRSA isolates (ST5-spa t002-SCCmec II [from two dogs] or ST30-spa t021-SCCmec IV [from a dog]) were concordant with those from veterinary staff members in the same clinics as the MRSA-positive dogs, with which they had potentially had contact. Most MRSA isolates from veterinary staff were the same genotype (SCCmec type II and spa type t002) as a major hospital-acquired MRSA clone in Japan. The remaining MRSA was the same genotypes as domestic and foreign community-associated MRSA. Measures against MRSA infection should be provided in private VCs. © 2014 The Societies and Wiley Publishing Asia Pty Ltd.

14C age of the ash found in the peat bed of upland dog, Nakagawa-Gun, Hokkaido

International Nuclear Information System (INIS)

Igarashi, Yaeko; Kondo, Tsutomu; Fujiwara, Koichiro.

1983-01-01

The determination of the 14 C age of volcanic ash forming thin layer, which was found in a peat bed, was carried out. The samples were collected from the peat bed which distributes on the flat top of upland about 450m above sea level. The moor spread in the experimental plantation of the agricultural department of Hokkaido University. The thin layer of volcanic ash was found 20 cm deep in the peat bed and with about 1-3 cm thickness. The determination of 14 C age was made on the peat directly beneath the volcanic ash layer, along with the mineralogical studies. The obtained 14 C age was 480 480 +- 100 Y.B.P. (A.D. 1470), and this is presumed to be the age of eruption of the volcanic ash. The color of the ash was greenish yellow or orange in wet state, and grayish white in dry state. The volcanic ash was fine grained pumiceous, and round or nearly round grains predominate. By macroscopic observation, the grains were found to be composed of fibrous volcanic glass. The volcanic ash was well sorted, and the central grain size was 0.11 mm. Heavy liquid method was applied for the determination of heavy minerals. The weight percentage of heavy minerals was 1.59, and the characteristic of this ash was the entire absence of amphibole. Further investigation is necessary for clarifying the distribution of volcanic ash and the source of eruption. (Ishimitsu, A.)

Field observations of the electrostatic charges of blowing snow in Hokkaido, Japan

Science.gov (United States)

Omiya, S.; Sato, A.

2011-12-01

An electrostatic charge of blowing snow may be a contributing factor in the formation of a snow drift and a snow cornice, and changing of the trajectory of own motion. However, detailed electrification characteristics of blowing snow are not known as there are few reports of charge measurements. We carried out field observations of the electrostatic charges of blowing snow in Tobetsu, Hokkaido, Japan in the mid winter of 2011. An anemovane and a thermohygrometer were used for the meteorological observation. Charge-to-mass ratios of blowing snow were obtained by a Faraday-cage, an electrometer and an electric balance. In this observation period, the air temperature during the blowing snow event was -6.5 to -0.5 degree Celsius. The measured charges in this observation were consistent with the previous studies in sign, which is negative, but they were smaller than the previous one. In most cases, the measured values increased with the temperature decrease, which corresponds with previous studies. However, some results contradicted the tendency, and the maximum value was obtained on the day of the highest air temperature of -0.5 degree Celsius. This discrepancy may be explained from the difference of the snow surface condition on observation day. The day when the maximum value was obtained, the snow surface was covered with old snow, and hard. On the other hand, in many other cases, the snow surface was covered with the fresh snow, and soft. Blowing snow particles on the hard surface can travel longer distance than on the soft one. Therefore, it can be surmised that the hard surface makes the blowing snow particles accumulate a lot of negative charges due to a large number of collisions to the surface. This can be supported by the results of the wind tunnel experiments by Omiya and Sato (2011). By this field observation, it was newly suggested that the electrostatic charge of blowing snow are influenced greatly by the difference of the snow surface condition. REFERENCE

Foods and beverages marketed in schools are typically of poor nutritional value. School districts may adopt policies and practices to restrict marketing of unhealthful foods and to promote healthful choices. Students' exposure to marketing practices differ by school demographics, but these differences have not yet been examined by district characteristics. We analyzed data from the 2012 School Health Policies and Practices Study to examine how food and beverage marketing and promotion policies and practices varied by district characteristics such as metropolitan status, size, and percentage of non-Hispanic white students. Most practices varied significantly by district size: a higher percentage of large districts than small or medium-sized districts restricted marketing of unhealthful foods and promoted healthful options. Compared with districts whose student populations were majority (>50%) non-Hispanic white, a higher percentage of districts whose student populations were minority non-Hispanic white (≤50% non-Hispanic white) prohibited advertising of soft drinks in school buildings and on school grounds, made school meal menus available to students, and provided families with information on school nutrition programs. Compared with suburban and rural districts, a higher percentage of urban districts prohibited the sale of soft drinks on school grounds and used several practices to promote healthful options. Preliminary findings showing significant associations between district demographics and marketing policies and practices can be used to help states direct resources, training, and technical assistance to address food and beverage marketing and promotion to districts most in need of improvement.

2018-04-01

To understand the properties of tides and tidal currents on the Pacific shelf off the southeastern coast of Hokkaido, Japan, we analyzed time series of 9 current meters that were moored on the shelf for 1 month to 2 years. Diurnal tidal currents such as the K1 and O1 constituents were more dominant than semi-diurnal ones by an order of magnitude. The diurnal tidal currents clearly propagated westward along the coast with a typical phase velocity of 2 m s-1 and wavelength of 200 km. Moreover, the shape and phase of the diurnal currents measured by a bottom-mounted ADCP were vertically homogeneous, except in the vicinity of the bottom boundary layer. These features were very consistent with theoretically estimated properties of free baroclinic coastal-trapped waves of the first mode. An annual (semi-annual) variation was apparent for the phase (amplitude) of the O1 tidal current, which was correlated with density stratification (intensity of an along-shelf current called the Coastal Oyashio). These possible causes are discussed in terms of the propagation and generation of coastal-trapped waves.

Accountability in district nursing practice: key concepts.

Science.gov (United States)

Griffith, Richard

2015-03-01

Public trust and confidence in district nurses is essential to the nurse-patient relationship that underpins effective care and treatment. That trust and confidence has even greater focus for district nurses who care for patients in their own homes. Those patients need to be able to count on the professionalism and probity of their district nurses. The professionalism and probity of district nurses is based on their accountability, which protects the public by imposing standards on district nurses and holds them answerable for their acts and omissions. This is the first of a series of articles on accountability in district nursing practice to mark the introduction of the revised Nursing and Midwifery Code on the 31 March 2015. This month's article considers the key concepts of accountability.

Interim district energy implementation

Energy Technology Data Exchange (ETDEWEB)

Fearnley, R.; Susak, W. [City of Vancouver, BC (Canada); Johnstone, I. [BCG Services Inc., Vancouver, BC (Canada)

2001-07-01

The concept of district energy was introduced in the City of North Vancouver, a city of 45,000, in 1997. A preliminary study was completed in 1997, followed by a tour of some district energy facilities in Finland in the same year. In 1999 a large district energy study was completed by a consultant. The study indicated the need for an investment of $15 million to implement district heating in the City. Lack of sufficient financial resources and immediately connectable heat load, the project was considered a non-starter. Some of the other factors leading to shelving the project included no current significant pricing advantages over competing energy sources and no current opportunity for cogeneration, given the low price that BC Hydro is willing to pay for independently produced power. The project, although shelved for the moment, has not been discarded. Planning and exploration are continuing, aided by the City's commitment to energy efficiency and conservation, its long term planning horizon and its significant influence over the development of some prime real estate.

Energy supply and urban planning projects: Analysing tensions around district heating provision in a French eco-district

International Nuclear Information System (INIS)

Gabillet, Pauline

2015-01-01

Through the analysis of energy supply choices, this article explores the way in which energy priorities and their climate-related features are incorporated into urban public policy. These choices must take account of different factors, as is the case with district heating, which is justified as a vehicle of renewable energy while subject to pressure in eco-districts because its techno-economic balances are destabilised by falls in demand. Our study focuses particularly on the city of Metz (France), which has chosen district heating as the primary source for provision for the municipal area and for its first eco-district. We analyse the tensions within these choices, with particular attention to the way in which they are negotiated inside municipal departments and with the local energy operator. This enables us to explore the tensions in defining the scale that governs decisions and the linkages between energy-related and urban priorities. - Highlights: • Analyses of tensions in the choice of energy supplies for eco-districts. •District heating networks can be vehicles of renewable energy. • District heating networks are threatened by drops in energy consumption. • Energy supply issues oppose urban planning and energy policy in municipal departments. • Technical and financial adjustments can be made by the municipality to justify its energy choices

District heating in Flensburg

Energy Technology Data Exchange (ETDEWEB)

Prinz, W.

1981-01-01

The majority of our population, but also of our authorities, are still skeptical or even disapproving towards district heating. The reasons of this negative attitude are partly psychological - e.g. the individualism of the Swiss and their dislike for too centralised structures and ''forced connections'' - but also the existence of finished gas supply networks and the fear of considerable pre-investments and torn streets over years. The following article - held as a speech on the information meeting ''District heating and the possible contribution of nuclear energy'' organised by the Swiss Association for Atomic Energy in Bern shows a practical problem solving at the example of the district heating in Flensburg and deals with these questions.

Shortage of energy increases profitability of district heating

International Nuclear Information System (INIS)

2003-01-01

Increased demand will cause the price of district heating to increase, but not to the level of the price of electricity. The cheapest heating alternative in Denmark, Norway and Sweden is district heating. In Norway, district heating is developed primarily for commercial buildings and housing cooperatives. Thirty per cent of all buildings under construction are prepared for district heating and the percentage will increase strongly in the coming time. The total net production of district heating in Norway in 2001 was 2000 GWh, which is only a small part of the total potential for district heating

Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees' personal values and goals are realised. The aim of the study was to evaluate employees' personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. The study was conducted in the Ngamiland and Mahalapye health districts. This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye) and 36% (Ngamiland) selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

The re-engineering of primary healthcare (PHC) is regarded as an essential precursor to the implementation of National Health Insurance in South Africa, but improvements in the provision of PHC services have been patchy. The authors contend that the role of well- functioning rural district hospitals as a hub from which PHC services can be most efficiently managed has been underestimated, and that the management of district hospitals and PHC clinics need to be co-located at the level of the rural district hospital, to allow for proper integration of care and effective healthcare provision.

Energy Assessment of Automated Mobility Districts

Energy Technology Data Exchange (ETDEWEB)

Chen, Yuche [National Renewable Energy Laboratory (NREL), Golden, CO (United States)

2017-08-03

Automated vehicles (AVs) are increasingly being discussed as the basis for on-demand mobility services, introducing a new paradigm in which a fleet of AVs displace private automobiles for day-to-day travel in dense activity districts. This project examines such a concept to displace privately owned automobiles within a region containing dense activity generators (jobs, retail, entertainment, etc.), referred to as an automated mobility district (AMDs). The project reviews several such districts including airport, college campuses, business parks, downtown urban cores, and military bases, with examples of previous attempts to meet the mobility needs apart from private automobiles, some with automated technology and others with more traditional transit based solutions. The issues and benefits of AMDs are framed within the perspective of intra-district, inter-district, and border issues, and the requirements for a modeling framework are identified to adequately reflect the breadth of mobility, energy, and emissions impact anticipated with AMDs.

In Norway, high prices on electric power have caused economic progress for the district heating companies. The price of district heating is determined by the prices of power and fuel oil. However, the government wants to remove the tax on electricity to the industry, which is the district heating companies' major group of customers, along with public buildings. This is likely to entail a great loss of income

Highlights: ► European excess heat recovery and utilisation by district heat distribution. ► Heat recovery in district heating systems – a structural energy efficiency measure. ► Introduction of new theoretical concepts to express excess heat recovery. ► Fourfold potential for excess heat utilisation in EU27 compared to current levels. ► Large scale excess heat recovery – a collaborative challenge for future Europe. -- Abstract: Increased recovery of excess heat from thermal power generation and industrial processes has great potential to reduce primary energy demands in EU27. In this study, current excess heat utilisation levels by means of district heat distribution are assessed and expressed by concepts such as recovery efficiency, heat recovery rate, and heat utilisation rate. For two chosen excess heat activities, current average EU27 heat recovery levels are compared to currently best Member State practices, whereby future potentials of European excess heat recovery and utilisation are estimated. The principle of sequential energy supply is elaborated to capture the conceptual idea of excess heat recovery in district heating systems as a structural and organisational energy efficiency measure. The general conditions discussed concerning expansion of heat recovery into district heating systems include infrastructure investments in district heating networks, collaboration agreements, maintained value chains, policy support, world market energy prices, allocation of synergy benefits, and local initiatives. The main conclusion from this study is that a future fourfold increase of current EU27 excess heat utilisation by means of district heat distribution to residential and service sectors is conceived as plausible if applying best Member State practice. This estimation is higher than the threefold increase with respect to direct feasible distribution costs estimated by the same authors in a previous study. Hence, no direct barriers appear with

The hooded crane is designated as an endangered species. The cranes breed primarily in wetlands in southeast Russia and China in summer. Most of the hooded crane population winters in the Izumi plain in Japan. It is difficult to know the contamination status of their habitat because of their vast breeding area. We determined the levels of Cd, Pb, As, (total) Hg, Se, Zn, and Cu in the liver, kidney, and muscle of hooded cranes that were found dead in Izumi in the periods 2003-2006 and 2014-2015 compared with the levels in red-crowned cranes in Hokkaido, Japan, as the only cranes in which these elements had been studied extensively. There were no notable differences between levels of the seven elements in the two periods. Overall, tissue levels of the elements examined in hooded cranes were comparable to those in red-crowned cranes except for Hg and Se. Tissue levels of Hg and Se were clearly lower in hooded cranes than in red-crowned cranes that were found dead from 2000. One lead poisoning case was confirmed. The results suggest that Hooded cranes wintering in Izumi are not extensively contaminated with the seven elements examined.

The situation of district heating, district cooling and energy supply in Hungary

District heating represents with 650.000 heated dwellings approximately 15% of the Hungarian residential heating market. Since 1990 there is stagnation at the number of connected dwellings because erection of large settlements with prefab buildings has been stopped, and latter ones represent more than 75% of the dwelling heating market. During the same period, residential heat demand shrunk by 33%, because metering of hot water consumption resulted in changing consumer habits, and because of slowly but step by step refurbishment of buildings and heating systems. In Hungary district heating is present in all large and most of the medium size cities, in 92 cities together. Out of them, there is also a single village with a local district heating system, which heats more than 60% of cottages. The capacity os systems is spreading to a large extent. Approximately 36-36% of all heated dwellings are in Budapest and in 10 large cities in the country, while 148 of the total 202 systems have less than 10 MW capacities. In the fuel structure of district heating it is characteristic the overwhelming role of natural gas consumption, which has exceeded 80% already. Only a few numbers of heating power plants are fuelled by crown coal. The use of renewables is growing continuous, but, together with waste and waste energy, it amounts merely 8% of the total fuel use. Oil consumption is negligible. Currently the most promising DH-market is the service sector (public buildings and commercial consumers). DH-companies can sell their surplus supply capacities on the competitive market. Residential market can be preserved only with better legal conditions and with improving of demand side management. The industrial heat market can be gained when the erection of new power plants will be harmonized with industrial development in the frame of territorial planning. District cooling is just at the beginning in Hungary. Many new commercial and office buildings are erected with air conditioning

When introducing and implementing a new technology for science teachers within a school district, we must consider not only the end users but also the roles and influence district personnel have on the eventual appropriation of that technology. School districts are, by their nature, complex systems with multiple individuals at different levels in the organization who are involved in supporting and providing instruction. Varying levels of support for new technologies between district coordinators and teachers can sometimes lead to counterintuitive outcomes. In this article, we examine the role of the district science coordinator in five school districts that participated in the implementation of an online resource discovery and sharing tool for Earth science teachers. Using a qualitative approach, we conducted and coded interviews with district coordinators and teachers to examine the varied responsibilities associated with the district coordinator and to infer the relationships that were developed and perceived by teachers. We then examine and discuss two cases that illustrate how those relationships could have influenced how the tool was adopted and used to differing degrees in the two districts. Specifically, the district that had high support for online resource use from its coordinator appeared to have the lowest level of tool use, and the district with much less visible support from its coordinator had the highest level of tool use. We explain this difference in terms of how the coordinator's promotion of teacher autonomy took distinctly different forms at those two districts.

Full Text Available Background: Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees’ personal values and goals are realised. Aim: The aim of the study was to evaluate employees’ personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. Setting: The study was conducted in the Ngamiland and Mahalapye health districts. Method: This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Results: Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye and 36% (Ngamiland selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. Conclusions: The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

Exploring the ethos of district nursing, 1885-1985.

Science.gov (United States)

Madsen, Wendy

2013-06-01

The history of district nursing in Australia explored in this paper reveals a continuity in the essential values held by district nurses for over a century. These nurses practised holistic, family-centred nursing from the very origins of district nursing service. The events surrounding the establishment of Community Health Centres in the 1970s challenged district nurses to reconsider their role, while at the same time reconfirming their essential ethos. These values that underpinned district nursing practice and challenges to these values are examined in this paper.

The efforts aim to meet consumers' needs for products that will prevent lifestyle diseases or the like. For this purpose, substances answering the purpose are extracted from Hokkaido-produced agricultural and aquatic biomasses, and prepared for testing. Researches are conducted on how they behave in the enzyme, cell, and biological systems, and active substances are isolated and identified. In relation to the aquatic biomass, a technology is established of extracting and separating DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid), taurine, etc., which are multivalent unsaturated fatty acids effective in preventing lifestyle diseases, from the unused parts of the squid. In relation to the agricultural biomass, antimicrobial active substances are extracted and separated from small fruit plants such as the chicory. Long-keeping foods are tentatively produced by the addition of dried powder of the chicory root tuber. In the elucidation of various biological regulatory substances contained in the Hokkaido-produced biomasses, they are tested for their abilities to resist microbes and active oxygen. Furthermore, verification tests are conducted by administering the substances to the senescence-accelerated mouse (SAM). (NEDO)

About the marshallian industrial district and the theory of the contemporary district. A brief critical reconstruction

Directory of Open Access Journals (Sweden)

Giacomo Becattini

2002-01-01

Full Text Available As a departing point, the paper presents the historical genesis of the concept of industrial district focusing on the scientific views of the pioneer of this field, Alfred Marshall. The concept has its origins in the observation of the current industrial reality, mainly of the British one. The purpose is to give an explanation to the difficulties of the classic theory and to study the challenges of the class conflicts. The economic conditions which launched British industrial districts were present, grosso modo, in Italy after the second World War. Some contributions have dealt with the little industrialisation of some Italian regions and using Marshallian thoughts have rediscovered the industrial districts phenomenon. This is the starting point of a high number of scientific contribution in Italy and abroad. Some of these international studies, particularly the ones made by Spanish experts, are quoted. The text analyses the link between districts-made in Italy with the competitive advantages of Italian products in many economic activities (i.e. clothing, shoes, furniture, etc.. Finally, in the third part the paper reviews some new contributions on the industrial district in Italy.

A frozen-stored blood clot of a wild brown bear cub Ursus arctos yesoensis that had been captured in Hokkaido, Japan was examined for piroplasma infection using polymerase chain reaction (PCR). Two 18S ribosomal RNA gene (SSU rDNA) sequences were generated. One 1565-bp sequence showed the highest similarity with B. gibsoni (95.9% identity) but, phylogenetically, was found to belong to a distinct lineage. The other sequence (1709-bp) could not be definitively assigned to a described taxon, sharing only limited homology to the closest named species (90.1% identity with C. felis). In order to enhance information obtained from the SSU rDNA sequence, further detection and sequence analysis of the CCTeta gene sequence were done revealing the simultaneous presence of three closely related genotypes (all in a monophyletic lineage) within a single bear host. This finding suggested the possibility that a new Babesia species (Babesia sp. UR1) might have been maintained in nature in wild brown bears. While the parasite's biology is yet unknown, to our knowledge, this is, excepting the single case documentation in 1910 of a hemoparasite in a bear at Russian zoo, the first reported case of piroplasms inhabiting a bear species.

Bossert, Thomas; Chitah, Mukosha Bona; Bowser, Diana

2003-12-01

Zambia implemented an ambitious process of health sector decentralization in the mid 1990s. This article presents an assessment of the degree of decentralization, called 'decision space', that was allowed to districts in Zambia, and an analysis of data on districts available at the national level to assess allocation choices made by local authorities and some indicators of the performance of the health systems under decentralization. The Zambian officials in health districts had a moderate range of choice over expenditures, user fees, contracting, targeting and governance. Their choices were quite limited over salaries and allowances and they did not have control over additional major sources of revenue, like local taxes. The study found that the formula for allocation of government funding which was based on population size and hospital beds resulted in relatively equal per capita expenditures among districts. Decentralization allowed the districts to make decisions on internal allocation of resources and on user fee levels and expenditures. General guidelines for the allocation of resources established a maximum and minimum percentage to be allocated to district offices, hospitals, health centres and communities. Districts tended to exceed the maximum for district offices, but the large urban districts and those without public district hospitals were not even reaching the minimum for hospital allocations. Wealthier and urban districts were more successful in raising revenue through user fees, although the proportion of total expenditures that came from user fees was low. An analysis of available indicators of performance, such as the utilization of health services, immunization coverage and family planning activities, found little variation during the period 1995-98 except for a decline in immunization coverage, which may have also been affected by changes in donor funding. These findings suggest that decentralization may not have had either a positive or

Hokkaido is one of the four largest island of Japan located in the northern, most of the area, where the atmospheric temperature goes lower than the other area in winter. Thus, an average energy consumption per capita is larger in amount during cold seasons. Nowadays this energy is supplied by fossil fuels. On the other hand, problem of the green house gas emission should be controlled as much as possible in order to avoid global warming. From this point of view, the authors have discussed with local people on the possibility to utilize nuclear clean energy in the daily life in Hokkaido district. Recently some leaders in local towns become interested to such activities and they want information about nuclear energy and related systems. It is a very good chance for us to exchange information on nuclear energy with regards to public acceptance, fears of nuclear power or radiation, the extent of satisfaction to be sure for construction of urban nuclear plants and requirements for such plants. We prepared technical presentation materials and visited a selected towns and continued discussion in various aspects. For example, proposal of a proto type design concept of a small reactor, safety, heat energy supply system. The audience was mainly representatives of the towns firstly and gradually ordinal people also attended the meetings. Based on the information, it could be expected to establish a concept for such district energy supply system. In this paper, some examples and results through these activities are presented.

To elucidate chemical components of soil gas in the Okushiri Island area, soil gas was collected by the method using charcoal adsorbent, and analysis was made by the GC/MS method. Out of the 19 measuring points, 17 points were set up near the measuring points in the FY 1998 survey by the finger print method. At the same measuring points, analytical survey by the MS method was also conducted to sort the type of soil gas. As a result of the GC/MS analysis, xylene or ethyl benzene was detected at 12 measuring points of all 19 measuring points, and from the distribution, it was predicted that there were anomaly zones in the district along the road of the Okushiri Island line and the district southward from the 5.8K Pass. These results were in harmony with the results of the survey by the finger print method. As to the sorting of soil gas based on the results of the MS analysis, the results were different at 8 measuring points from those of the survey by the finger print method in FY 1998. It was considered that the cause was the accidental vaporization of a large quantity of acetaldehyde, and acetaldehyde was regarded as a noise gas component that does not reflect the geothermal structure.

Detection of iodine-129 in some environmental samples

International Nuclear Information System (INIS)

Ikeda, Nagao

1981-01-01

The recent accumulation of the long-lived isotope of iodine, 129 I, which is released in environment by the peaceful use of nuclear energy or nuclear test explosion is becoming important in the view point of the internal exposure by the low level radiation. The studies on the detection of determination of 129 I in environmental samples so far published are still very few. The authors tried to detect 129 I in some Japanese seaweeds and soil samples with the aid of the activation method by using the nuclear reaction of 129 I(n, #betta#) 130 I. The samples analysed in this work are tangle (Laminaria japonica) for daily food grown in Hidaka, Hokkaido and uncultivated soil collected in Tokai, Ibaraki Pref. As the #betta#-ray peak indicator for 130 I, cesium oxide and the aged radioisotope product of 131 I are also subjected to the neutron irradiation. From cesium oxide, 130 I is formed by the reaction of 133 Cs(n, α) 130 I. An aged vial of the 131 I product is expected to contain very minute amounts of 129 I which is also produced both by the fission of uranium and neutron capture reaction of tellurium followed by #betta# - -decay. The #betta#-ray spectra for the soil sample, cesium oxide and the aged 131 I vial are shown in Fig. 1. No appreciable peak was found for the seaweeds sample. In the #betta#-ray spectra for irradiated cesium oxide and the aged 131 I vial, several typical peaks for 130 I were observed. By comparing with these peaks, several small peaks which appear at around 418, 536 and 739 keV in the soil sample can be attributed to those of 130 I. The 129 I content in the soil sample is roughly estimated to be 2 x 10 - 10 Bq/g. (author)

Swedish district heating - owners, prices and profitability

International Nuclear Information System (INIS)

Andersson, Sofie; Werner, S.

2001-01-01

Owners, prices and profitability are examined in this report for 152 Swedish district heating companies during 1999. Only public information available has been used: Prices from a national annual consumer study, energy supplied, lengths of district heating pipes installed, and average prices for energy supplied. These companies are responsible for 96 % of all district heat supplied in Sweden. District heating systems owned by municipalities were responsible for 65 % of all district heat supply, while the share of power companies was 34 %. Other private owners accounted for 1 %. Only 12 % of the board members are women and more than 40 % of the companies have no woman in the board. The prices gathered by the annual consumer study are good estimates of the price level of district heating in Sweden. The average revenues are only 4,1 % lower than the effective average of prices gathered. Price of district heating decrease with size and market share. Use of combined heat and power plants decrease prices slightly. Lower prices with size can mainly be explained by lower energy supply costs. Calculated rates of return in relation to calculated replacement values increase slightly by size and are almost independent of age and market share. The purport of these conclusions is that the district heating companies share the cost reduction from size with their customers, while the whole benefit from high market shares is repaid to the customers. Calculated rates of return vary among the owner groups examined. Lower rates are accepted by municipalities, while power companies have higher rates at the average costs used. Total replacement costs for the 152 companies has been estimated to 89 billion Swedish crowns or 10 billion Euro. Only correlation analyses using one dimension have been used in this study. A higher degree of quality can be obtained by using multi-dimensional analyses

2018-04-01

The Kuril harbor seal around Hokkaido is presently recovering from a resource crisis while conflicts with local fisheries have become a concern. However, its feeding habits, which are fundamental information for taking proper preventive measures, are still poorly understood. We thus examined the infection status of a trophically-transmitted parasite, Corynosoma strumosum in the seals of Erimo Cape, to assess the host's feeding habits with a practical view of the parasite as a biological indicator. A total of 2802 worms were found from 20 male and 20 female by-caught animals in salmon set nets within local fisheries during August to November 2014. The parasite abundance was explained mainly by the host's developmental stage and intestinal length while weakly affected by gender and body size, through an estimation of generalized linear models combined with hierarchical partitioning. Considering the past records that demersal fishes are the probable main sources of infection, the infection level may owe to individual host differences regarding these sources and/or feeding grounds with relating the host characteristics. This supports that the resource management of Kuril harbor seals requires careful consideration of the individual differences in feeding behavior. Copyright © 2017 Elsevier B.V. All rights reserved.

Short-Term Response of Sasa Dwarf Bamboo to a Change of Soil Nitrogen Fertility in a Forest Ecosystem in Northern Hokkaido, Japan

Directory of Open Access Journals (Sweden)

Tsunehiro Watanabe

2016-04-01

Full Text Available In forest ecosystems, a change of soil nitrogen (N cycling after disturbance is regulated by various factors. Sasa dwarf bamboo (hereafter referred to as Sasa is an understory plant that grows thickly on the forest floor in northern Hokkaido, Japan. However, the ecosystem function of Sasa after disturbances in the soil N cycling is not fully understood. The purpose of this study was to determine the short-term response of Sasa to a change of soil N fertility. Biomass, litterfall, litter decomposition, soil N pool, and N leaching from soil were measured in control, and low- (5 g N m−2 year−1 and high-N (15 g N m−2 year−1 addition plots. Sasa immobilized much N as the soil N fertility increased. However, the leaf N concentration in aboveground biomass did not increase, suggesting that the N in leaves was maintained because of the increase of leaf biomass. As a result, the decomposition and mineralization rates of the produced litter before and after N addition were comparable among plots, even though the soil inorganic N fertility increased greatly. These results suggest that immediate response of Sasa to an increase of soil inorganic N mitigates the excess N leaching from soil.

Full Text Available After the liberation of Nis from the Turks which took place on January 11th, 1878, there were two military hospitals: one was next to The Skull Tower and the other on the road to Leskovac and there was Islahana the civil institution which was not the forerunner of the district hospital in Nis. At first, they founded the military hospital in Nis in 1878 and then they founded The District Hospital on July 17th in 1881. The first director of the District hospital was Anton Zajicek. He is also the first graduated medical doctor in Nis. The District Hospital was situated on the left bank of the Nisava river in a private house.

Scenario development of long-term evolution for deep hydrochemical conditions in Horonobe area, Hokkaido, Japan

2009-01-01

A methodology to estimate long-term hydrochemical evolution of deep underground is indispensable for the safe geological isolation of high-level radioactive waste (HLW). This study demonstrates the methodology by illustrating scenarios of past geological events, processes, and their interrelationships with present-day hydrochemical conditions. Besides, we infer long-term variations of groundwater chemistry at Horonobe, Hokkaido, Japan. The region is underlain mainly by Neogene to Quaternary marine sedimentary rocks, (the Wakkanai Formation (Fm) and the overlying Koetoi Fm: siliceous and diatomaceous mudstones). During various events in the geological past, such as deposition, compaction, uplift, and denudation, and the more recent Neotectonic activities in this area, highly permeable hydrogeological structures formed at depths not over than 400 m below ground level in the Wakkanai Fm. The hydrogeological system can be subdivided into three hydrogeological sub-systems: (1) overlying, relatively low permeability Koetoi Fm., (2) highly permeable, upper Wakkanai Fm at depths less than 400 m and (3) relatively low permeability Wakkanai Fm, at depths greater than 400 m. The present-day hydrochemical conditions in each sub-system have been influenced by hydrogeological properties and hydraulic conditions over a long period. In subsystems 1 and 2, recharging with meteoric water flushed connate seawater during uplifting and denudation during the last 1 Ma. In contrast, fossil seawater with one-third to one-half the salinity of present-day seawater has been preserved in subsystem 3. The relatively low permeability sequence in sub-system 3 was formed by the compaction of diatomaceous mudstone during subsidence prior to 1.0 Ma. After that, changes of climatic conditions and geographical features would not have influenced groundwater flow. The groundwater chemistry evolved from seawater during long-term geochemical diagenesis in a relatively closed system. The long

Is Swedish district heating operating on an integrated market? – Differences in pricing, price convergence, and marketing strategy between public and private district heating companies

International Nuclear Information System (INIS)

Åberg, M.; Fälting, L.; Forssell, A.

2016-01-01

The deregulation of the Swedish electricity market in 1996 made it possible to operate municipal district heating commercially. Until that time district heating had been organized mainly as municipal utilities. After 1996 district heating is instead expected to function on a market. In competitive and integrated markets, prices are expected to be equal, or converging. To find out if district heating operates on an integrated market the differences in price levels, price convergence, price strategy, and business goals, among municipal, private and state owned district heating companies are investigated. Price statistics was used along with results from a questionnaire that was answered by representatives for 109 Swedish district heating companies. The results show that prices among district heating systems do not converge significantly and that variations in prices among municipal systems are larger than among private and state owned systems. Furthermore, despite the fact that district heating is supposed to be commercial, a vast majority of district heating companies apply cost-based pricing and not market pricing. The municipal companies give priority to political goals before financial goals. The conclusion is that a Swedish integrated market for heat has not yet evolved, and some district heating price-controlling mechanism is necessary. - Highlights: • Price statistics and owner type data were used along with results from a questionnaire. • Results show that prices among district heating systems do not converge. • Municipal district heating companies still apply cost-based pricing to a large extent. • District heating companies are not operating on an integrated market for heat. • Some price-controlling mechanism for district heating is necessary.

Influencing Swedish homeowners to adopt district heating system

Improved energy efficiency and greenhouse gas mitigation could be achieved by replacing resistance heaters with district heating system. In 2005, only about 8% of the Swedish detached houses had district heating system. The expansion of such systems largely depends on homeowners' adoption decisions. And, to motivate homeowners to adopt district heating, it is essential to understand their decision-making process. In this context, in June 2005 we carried out a questionnaire survey of about 700 homeowners who lived in the city of Oestersund in houses with resistance heaters (baseline survey). About 84% of the respondents did not intend to install a new heating system. Since then these homeowners were influenced by (a) an investment subsidy by the Swedish government to replace resistance heaters with district heating, a brine/water-based heat pump, or a biomass-based heating system and (b) a marketing campaign by the municipality-owned district heating company. This paper analyses how these two measures influenced about 78% of the homeowners to adopt the district heating system. For this purpose we carried out a follow-up survey of the same homeowners in December 2006 (resurvey). Results showed that the investment subsidy and the marketing campaign created a need among the homeowners to adopt a new heating system. The marketing campaign was successful in motivating them to adopt the district heating system. The marketing strategy by the district heating company corresponds to the results obtained in the baseline survey. (author)

Full Text Available Drug is one of the essential elements in healthcare that should be effectively and efficiently managed. Following thedecentralization in 2001 in Indonesia, drug management has changed in district drug management units and also in District General Hospitals. Certainly this condition influences the sustainability of drug access in primary health care such as in Community Health Center and District General Hospital, especially in drug financing policy. A cross sectional descriptive study to obtain information on drug management in public healthcare in district had been carried out between July and December 2006 in 10 District Public Drug Management Units from 10 district health offices and 9 district general hospitals as samples. Data were collected by interviewing heads of Drug Section in District Health Offices and heads of Hospital Pharmacies using structured questionnaires and observing drug storage in District Drug Management Units, Community Health Centers, and Hospital Pharmacies. Results of the study show that drug planning in District Health Offices and General Hospitals did not meet the basic real need in some districts nor District Hospitals. The minimum health service standards had no been achieved yet. Furthermore, drug procurement, storage and recording as well as reporting was not good enough either, such as shown by the existence of expired drugs. Lead time for drug delivery to community health centers in some districts was longer than the average of lead time in the past 3 years.

Sudbury District Energy - a public/private partnership model

International Nuclear Information System (INIS)

Prudhomme, H.

1999-01-01

The issue of public/private partnership as it relates to the Sudbury District Energy Project was discussed. When completed, it will be the first cogeneration-based district heating and cooling project involving private sector/public sector partnership in Canada. The equal partners include Toromont Energy and Sudbury Hydro. Sudbury Hydro is a community owned energy and communications utility. It was the first electric utility in Ontario to retail natural gas in the new competitive market place. The Sudbury District Energy Project began in 1996, when the utility began the development of a community district energy system in partnership with the City of Sudbury. At the time, the downtown district heating/cooling system supplied cold and hot water to Sudbury's Wellness Centre. In 1998, Toromont Energy accepted a 50/50 partnership arrangement between themselves and the public sector partners to form the Sudbury District Energy Corporation. Sudbury Hydro will benefit from the project because it will reduce their peak loads and it will also be an alternate source of revenue. It is expected that the project will displace 39,600 tons of carbon dioxide, a greenhouse gas which contributes to global warming

Kwamie, Aku; van Dijk, Han; Ansah, Evelyn K; Agyepong, Irene Akua

2016-01-01

The district health system in Ghana today is characterized by high resource-uncertainty and narrow decision-space. This article builds a theory-driven historical case study to describe the influence of path-dependent administrative, fiscal and political decentralization processes on development of the district health system and district manager decision-space. Methods included a non-exhaustive literature review of democratic governance in Ghana, and key informant interviews with high-level health system officials integral to the development of the district health system. Through our analysis we identified four periods of district health system progression: (1) development of the district health system (1970–85); (2) Strengthening District Health Systems Initiative (1986–93); (3) health sector reform planning and creation of the Ghana Health Service (1994–96) and (4) health sector reform implementation (1997–2007). It was observed that district manager decision-space steadily widened during periods (1) and (2), due to increases in managerial profile, and concerted efforts at managerial capacity strengthening. Periods (3) and (4) saw initial augmentation of district health system financing, further widening managerial decision-space. However, the latter half of period 4 witnessed district manager decision-space contraction. Formalization of Ghana Health Service structures influenced by self-reinforcing tendencies towards centralized decision-making, national and donor shifts in health sector financing, and changes in key policy actors all worked to the detriment of the district health system, reversing early gains from bottom-up development of the district health system. Policy feedback mechanisms have been influenced by historical and contemporary sequencing of local government and health sector decentralization. An initial act of administrative decentralization, followed by incomplete political and fiscal decentralization has ensured that the balance of

To further elucidate the migration history of the brown bears (Ursus arctos) on Hokkaido Island, Japan, we analyzed the complete mitochondrial DNA (mtDNA) sequences of 35 brown bears from Hokkaido, the southern Kuril Islands (Etorofu and Kunashiri), Sakhalin Island, and the Eurasian Continent (continental Russia, Bulgaria, and Tibet), and those of four polar bears. Based on these sequences, we reconstructed the maternal phylogeny of the brown bear and estimated divergence times to investigate the timing of brown bear migrations, especially in northeastern Eurasia. Our gene tree showed the mtDNA haplotypes of all 73 brown and polar bears to be divided into eight divergent lineages. The brown bear on Hokkaido was divided into three lineages (central, eastern, and southern). The Sakhalin brown bear grouped with eastern European and western Alaskan brown bears. Etorofu and Kunashiri brown bears were closely related to eastern Hokkaido brown bears and could have diverged from the eastern Hokkaido lineage after formation of the channel between Hokkaido and the southern Kuril Islands. Tibetan brown bears diverged early in the eastern lineage. Southern Hokkaido brown bears were closely related to North American brown bears.

District heating in Italy: Extent of use

International Nuclear Information System (INIS)

Sacchi, E.

1992-01-01

The Author surveys the trend that has been established over the last two decades in the use of district heating in Italy. Comparison with the European situation reveals that Italy is lagging behind. The reason for this the Author states is the Italian public's aversion to unknown risks involved in the utilization of innovative technologies associated with cogeneration/district heating (current preference is given to autonomous methane fuelled building space heating systems), and the current opinion of some misinformed public administrations that cogeneration/district heating plants are too costly. Citing the successful campaign by the natural gas industry to promote the public acceptance of methane as a safe, readily available and competitively priced energy source, he suggests that similar efforts be made to have the public also accept cogeneration (with methane fired gas turbines)/district heating as being safe and environmentally, as well as, economically beneficial

Nuclear power for district heating

International Nuclear Information System (INIS)

Lyon, R.B.; Sochaski, R.O.

1975-09-01

Current district heating trends are towards an increasing use of electricity. This report concerns the evaluation of an alternative means of energy supply - the direct use of thermal energy from CANDU nuclear stations. The energy would be transmitted via a hot fluid in a pipeline over distances of up to 40 km. Advantages of this approach include a high utilization of primary energy, with a consequent reduction in installed capacity, and load flattening due to inherent energy storage capacity and transport delays. Disadvantages include the low load factors for district heating, the high cost of the distribution systems and the necessity for large-scale operation for economic viability. This requirement for large-scale operation from the beginning could cause difficulty in the implementation of the first system. Various approaches have been analysed and costed for a specific application - the supply of energy to a district heating load centre in Toronto from the location of the Pickering reactor station about 40 km away.

Thermoluminescence dating of a tephra deposit of the ''Toya'' volcano (Hokkaido, Japan)

Sanzelle, S.; Pilleyre, Th.; Miallier, D.; Fain, J.; Ganzawa, Y.

2000-01-01

Toya caldera which has a diameter of about 10 km and a hexagonal form is situated in the southern part of Hokkaido, northern Japan. The water level of the caldera lake is 84 m and the highest altitude of the central dome in the lake, Nakajima is 454 m. The volcanic activity is divided into 4 stages of the Toya Pyroclastic Flow Deposits 1 to 4. This tephra is composed of rhyolitic ash which is rich in glass and associated with hornblende, pyroxene and quartz. In a previous work, the age of eruption was estimated by utilising several dating methods and the stratigraphical correlation with other tephra. The ages which resulted from FT (Fission Tracks) dating and TL (Thermoluminescence) dating indicated 130±30 ka and 103-134 ka, respectively. The overall estimated age, received from other information such as the environmental change of mineral marine deposits, has been accepted as 100-120 ka by Quaternary Researchers. Because this tephra can be found widely in the Quaternary field, many researchers can use it as an appropriate age indicator of the 5c or 5d Isotope Stage, the middle age of the Last Internal Glacial Age. A new dating program was initiated, using the red TL of quartz grains extracted from the tephra. The samples studied in the present work came from the southern part of the deposits, around 15 km away from the centre of the caldera. The TL measurements, using the red signal of xenolithic quartz grains from the tephra, were made at Aubiere. Three distinct sets of samples were measured. The first two differ from each other by grain size, 250-350 μm (TOYA2, Aset2) and 150-250 μm (TOYA1,Bset3), and were irradiated in Japan and the third one, 250-350 μm (TOYA2, Cset2) was irradiated at Aubiere. The annual dose rate experienced by the samples during burial was estimated from a compilation of radionuclide contents evaluated in Japan using NAA and in France, using low level gamma spectroscopy (Aubiere) and ICPMS (CRPG, Nancy).

This report gives information on the work carried out and the results obtained in Denmark on storages for large solar heating plants in district heating networks. Especially in Denmark the share of district heating has increased to a large percentage. In 1981 around 33% of all dwellings in DK were connected to a district heating network, while the percentage in 2006 was about 60% (in total 1.5 mio. dwellings). In the report storage types for short term storage and long term storages are described. Short term storages are done as steel tanks and is well established technology widely used in district heating networks. Long term storages are experimental and used in connection with solar heating. A number of solar heating plants have been established with either short term or long term storages showing economy competitive with normal energy sources. Since, in the majority of the Danish district heating networks the heat is produced in co-generation plants, i.e. plants producing both electricity and heat for the network, special attention has been put on the use of solar energy in combination with co-generation. Part of this report describes that in the liberalized electricity market central solar heating plants can also be advantageous in combination with co-generation plants. (au)

Local business models for district heat production; Kaukolaemmoen paikalliset liiketoimintamallit

Energy Technology Data Exchange (ETDEWEB)

Hakala, L.; Pesola, A.; Vanhanen, J.

2012-12-15

Local district heating business, outside large urban centers, is a profitable business in Finland, which can be practiced with several different business models. In addition to the traditional, local district heating business, local district heat production can be also based on franchising business model, on integrated service model or on different types of cooperation models, either between a local district heat producer and industrial site providing surplus heat or between a local district heat producer and a larger district heating company. Locally available wood energy is currently utilized effectively in the traditional district heating business model, in which a local entrepreneur produces heat to consumers in the local area. The franchising model is a more advanced version of the traditional district heating entrepreneurship. In this model, franchisor funds part of the investments, as well as offers centralized maintenance and fuel supply, for example. In the integrated service model, the local district heat producer offers also energy efficiency services and other value-added services, which are based on either the local district heat suppliers or his partner's expertise. In the cooperation model with industrial site, the local district heating business is based on the utilization of the surplus heat from the industrial site. In some cases, profitable operating model approach may be a district heating company outsourcing operations of one or more heating plants to a local entrepreneur. It can be concluded that all business models for district heat production (traditional district heat business model, franchising, integrated service model, cooperative model) discussed in this report can be profitable in Finnish conditions, as well for the local heat producer as for the municipality - and, above all, they produce cost-competitive heat for the end-user. All the models were seen as viable and interesting and having possibilities for expansion Finland

Reza MOHAMMADY GARFAMY

2011-03-01

Full Text Available This paper provides a comparison study of industrial districts in two European countries, Spain and Sweden, using the conceptual framework of corporation. The relevance of this approach is based on the specific qualities that the industrial districts have, including the preexisting conditions, local traditions, products and production characteristics, marketing strategies, local policies and present challenges. The findings indicate the ways in which different patterns of inter-firm relationships, organization of production and dynamics of local alliances have shaped divergent regional responses to the industrial construction.

Perfluorinated chemicals (PFCs) disrupt cholesterol homeostasis. All steroid hormones are derived from cholesterol, and steroid hormones such as glucocorticoids and androgenic hormones mediate several vital physiologic functions. However, the in utero effects of PFCs exposure on the homeostasis of these steroid hormones are not well understood in humans. We examined the relationship between prenatal exposure to perfluorooctane sulfonate (PFOS)/perfluorooctanoate (PFOA) and cord blood levels of glucocorticoid and androgenic hormones. We conducted a hospital-based birth cohort study between July 2002 and October 2005 in Sapporo, Japan (n = 514). In total, 185 mother-infant pairs were included in the present study. Prenatal PFOS and PFOA levels in maternal serum samples were measured using liquid chromatography-tandem mass spectrometry (LC-MS-MS). Cord blood levels of glucocorticoid (cortisol and cortisone) and androgenic hormones [dehydroepiandrosterone (DHEA) and androstenedione] were also measured in the same way. We found a dose-response relationship of prenatal PFOS, but not PFOA, exposure with glucocorticoid levels after adjusting for potential confounders. Cortisol and cortisone concentrations were -23.98-ng/mL (95% CI: -0.47.12, -11.99; p for trend = 0.006) and -63.21-ng/mL (95% CI: -132.56, -26.72; p for trend blood.

2002-11-01

The aim of this study was to clarify the "Sick House Syndrome" which has recently received increasing attention, and to investigate relationships between symptoms and the state of general dwellings in Hokkaido. Questionnaires were sent to residents in 1775 dwellings, mainly solitary houses built or remodeled within the past few years by 24 construction companies in Sapporo and its environs, and answers was received from 564. The questionnaires included queries about building structure and characteristics, the residents' habits in the home, and subjective symptoms. We requested one resident who had the most severe symptoms in the dwelling to answer a questionnaire about symptoms. We classified the symptoms into 11 categories, and selected those that developed or were aggravated after the building or remodeling. We defined dwellings in which inhabitants complained of one or more categories of symptoms as the group with sick-house-related disease (developed or aggravated group: DA group), and those in which the inhabitants complained of two or more symptoms as the group with sick house syndrome (more than one organic symptom group: MO group)". Associations between symptoms and dwellings were then studied. There were 201 dwellings for which residents complained of symptoms (37.2%). Of these, 94 were in the DA group (16.7%), and 57 (10.1%) in the MO group. The symptoms that developed or were aggravated after building or remodeling of the dwellings were throat, 7.1%, dermal, 6.9%, psychoneural, 5.3%, eye, 5.1%, and nasal problems, 4.1%. Unpleasant odors form furniture were significant in both groups (DA: crude odds ratio (OR) 2.66, MO: OR 3.24). Use of aromatics was significant in group DA (OR 1.78). Condensation on windows and mold growth in the dwellings were significant in both groups (condensation on windows; DA: OR 2.98, MO: OR 3.32, mold growth; DA: OR 3.11, MO: OR 3.24). In addition, the percentage of dwellings for which residents complained of symptoms increased

Clean and safe supply of fish and shellfish to clear the HACCP regulation by use of clean and cold deep ocean water in Rausu, Hokkaido, Japan

Science.gov (United States)

Mac Takahashi, Masayuki; Yamashita, Kazunori

2005-07-01

For the supply of fish and shellfish to consumers in fresh condition, clean handling after catch from the sea is essential. According to HACCP (Hazard Analysis and Critical Control Points), it is important to meet such requirement by keeping fish and shellfish under a certain low temperature and clean conditions after catching. The deep ocean water (DOW) characterized by low temperature and cleanliness has been chosen for fish and shellfish handlings, particularly for salmon, cod, and sea urchin in Town ‘Rausu’ in Hokkaido, Japan. DOW below 2.9’C of an amount of nearly 5 000m3 is planned to be pumped up every day from a depth of about 350 m, and temporarily stored in a large simulated tank on land. DOW is then supplied to fish boats through hydrants distributed throughout the harbor and used for keeping salmon in clean and cold conditions. Ice made from DOW is also used for lowering temperature if necessary. DOW and ice made from DOW are also used during the transportation of fish and shellfish. The entire system is scheduled to be completed by the summer of 2005.

This study aimed to compare body growth, metabolic, and reproductive hormonal changes in trained Thoroughbred yearling horses under different climate conditions with and without light supplementation (LS). Thoroughbred yearlings raised at research centers of the Japan Racing Association in Hokkaido (north) or Miyazaki (south) were divided into control and LS groups. In the LS groups, 44 colts and 47 fillies from Hokkaido and 11 colts and 11 fillies from Miyazaki were exposed to LS with an extended photoperiod of 14.5 hr of daylight and 9.5 hr of darkness. One week before and once a month after LS, circulating total thyroxine (T4), insulin-like growth factor-I (IGF-1), prolactin (PRL), cortisol, and progesterone (P4) concentrations were measured by radioimmunoassay and fluoroimmunoassay, respectively. Growth parameters, including body weight, height, girth, and cannon bone circumferences, were measured monthly. Hair coat (HC) condition was scored. Under natural conditions, the T4 concentrations of Hokkaido yearlings tended to be higher, whereas the IGF-1 (colt) and PRL levels were significantly lower than those of yearlings in Miyazaki. Growth parameters and HC scores were lower in Hokkaido yearlings. With LS, the PRL and P4 concentrations in Hokkaido and Miyazaki were higher, and the first ovarian activity tended to be earlier than in the controls. Only LS Hokkaido yearlings showed significantly higher HC scores than the controls. Comparing the different climates among the LS yearlings, the levels of PRL and P4 and the HC scores in Hokkaido yearlings increased and reached levels similar to those in Miyazaki yearlings. The body weight and girth increment percentages of Hokkaido yearlings in January dramatically decreased and then eventually increased to levels similar to those of Miyazaki yearlings. This suggested that yearlings in naturally colder Hokkaido exhibit higher basal metabolism to maintain homeostasis. However, providing LS may help to improve growth and

District nursing workforce planning: a review of the methods.

Science.gov (United States)

Reid, Bernie; Kane, Kay; Curran, Carol

2008-11-01

District nursing services in Northern Ireland face increasing demands and challenges which may be responded to by effective and efficient workforce planning and development. The aim of this paper is to critically analyse district nursing workforce planning and development methods, in an attempt to find a suitable method for Northern Ireland. A systematic analysis of the literature reveals four methods: professional judgement; population-based health needs; caseload analysis and dependency-acuity. Each method has strengths and weaknesses. Professional judgement offers a 'belt and braces' approach but lacks sensitivity to fluctuating patient numbers. Population-based health needs methods develop staffing algorithms that reflect deprivation and geographical spread, but are poorly understood by district nurses. Caseload analysis promotes equitable workloads but poorly performing district nursing localities may continue if benchmarking processes only consider local data. Dependency-acuity methods provide a means of equalizing and prioritizing workload but are prone to district nurses overstating factors in patient dependency or understating carers' capability. In summary a mixed method approach is advocated to evaluate and adjust the size and mix of district nursing teams using empirically determined patient dependency and activity-based variables based on the population's health needs.

Full Text Available Development of health could not be conducted by the government itself but needs active participation from various sectors. District/municipality governments should mobilize potential resources in the areas so the actively involved in the development of health. Hence the district/municipality governments urge to facilitate development of District Health Committee (DHC as a media composed of all parties that actively involved in the development of health. This is in accordance to the Ministry of Health Letter Number 004/Menkes/SK/I/2003 on policy and strategies on decentralization in health. The study aimed to determine policy about DHC, to facilitate for development DHC and to determine dynamics in the developmentof DHC in Kutai Kartanegara District, East Kalimantan Province and Bojonegoro District, East Java Province. Data were collected by depth interview from staffs at District Health Offices, Health Proffesion Organizations, Non Government Organizations, academics, and the social organizations. Results showed in Kutai Kartanegara District there was institution named District Health Assembly. The institution was formed by the requirement from Asian Development Bank, the funding agency to Decentralized Health Service (DHS Project in Kutai Kartanegara District. The institution has not yet functioned properly and its existence was not socialized widely. In Bojonegoro District, the DHC was thought as an ideal condition in the development of health which existence is needed by some institutions. As the District Health Office was not sure for it hence the development of DHC was assumed not in need. Key words: development of health, District Health Committee, District Health Assembly

Robust small area estimation of poverty indicators using M-quantile approach (Case study: Sub-district level in Bogor district)

Science.gov (United States)

Girinoto, Sadik, Kusman; Indahwati

2017-03-01

The National Socio-Economic Survey samples are designed to produce estimates of parameters of planned domains (provinces and districts). The estimation of unplanned domains (sub-districts and villages) has its limitation to obtain reliable direct estimates. One of the possible solutions to overcome this problem is employing small area estimation techniques. The popular choice of small area estimation is based on linear mixed models. However, such models need strong distributional assumptions and do not easy allow for outlier-robust estimation. As an alternative approach for this purpose, M-quantile regression approach to small area estimation based on modeling specific M-quantile coefficients of conditional distribution of study variable given auxiliary covariates. It obtained outlier-robust estimation from influence function of M-estimator type and also no need strong distributional assumptions. In this paper, the aim of study is to estimate the poverty indicator at sub-district level in Bogor District-West Java using M-quantile models for small area estimation. Using data taken from National Socioeconomic Survey and Villages Potential Statistics, the results provide a detailed description of pattern of incidence and intensity of poverty within Bogor district. We also compare the results with direct estimates. The results showed the framework may be preferable when direct estimate having no incidence of poverty at all in the small area.

Industrial excess heat for district heating in Denmark

International Nuclear Information System (INIS)

Bühler, Fabian; Petrović, Stefan; Karlsson, Kenneth; Elmegaard, Brian

2017-01-01

Highlights: •Method for utilisation potential of industrial excess heat for district heating. •Industrial excess heat from thermal processes is quantified at single production units. •Linking of industrial excess heat sources and district heating demands done in GIS. •Excess heat recovery using direct heat transfer and heat pumps. •5.1% of the Danish district heating demand could be supplied by industrial excess heat. -- Abstract: Excess heat is available from various sources and its utilisation could reduce the primary energy use. The accessibility of this heat is however dependent amongst others on the source and sink temperature, amount and potential users in its vicinity. In this work a new method is developed which analyses excess heat sources from the industrial sector and how they could be used for district heating. This method first allocates excess heat to single production units by introducing and validating a new approach. Spatial analysis of the heat sources and consumers are then performed to evaluate the potential for using them for district heating. In this way the theoretical potential of using the excess heat for covering the heating demand of buildings is determined. Through the use of industry specific temperature profiles the heat usable directly or via heat pumps is further found. A sensitivity analysis investigates the impact of future energy efficiency measures in the industry, buildings and the district heating grid on the national potential. The results show that for the case study of Denmark, 1.36 TWh of district heat could be provided annually with industrial excess heat from thermal processes which equals 5.1% of the current demand. More than half of this heat was found to be usable directly, without the need for a heat pump.

Environmental issues and competitiveness of district heating systems

International Nuclear Information System (INIS)

Kypreos, S.

1991-01-01

The advantages of district heating systems are evaluated in competition to individual heating for the Swiss markets. The preservation of the environmental quality on the national (clean air concept) and global scale (Toronto recommendation) is formulated as constraint of the energy system. The implications of these constraints for the economic competition of district heating is evaluated. The study estimates the evolution of energy demand in the heating markets and shortly describes the technical possibilities in satisfying demand by a set of conventional heating systems, systems using renewable energy sources, energy conservation measures and district heating systems based on conventional or nuclear energy sources. The main conclusion is that small capacity nuclear district heating systems, if acceptable, could enhance the flexibility of the Swiss energy system in respect to CO 2 control.

Energy and exergy analysis of low temperature district heating network

International Nuclear Information System (INIS)

Li, Hongwei; Svendsen, Svend

2012-01-01

Low temperature district heating with reduced network supply and return temperature provides better match of the low quality building heating demand and the low quality heating supply from waste heat or renewable energy. In this paper, a hypothetical low temperature district heating network is designed to supply heating for 30 low energy detached residential houses. The network operational supply/return temperature is set as 55 °C/25 °C, which is in line with a pilot project carried out in Denmark. Two types of in-house substations are analyzed to supply the consumer domestic hot water demand. The space heating demand is supplied through floor heating in the bathroom and low temperature radiators in the rest of rooms. The network thermal and hydraulic conditions are simulated under steady state. A district heating network design and simulation code is developed to incorporate the network optimization procedure and the network simultaneous factor. Through the simulation, the overall system energy and exergy efficiencies are calculated and the exergy losses for the major district heating system components are identified. Based on the results, suggestions are given to further reduce the system energy/exergy losses and increase the quality match between the consumer heating demand and the district heating supply. -- Highlights: ► Exergy and energy analysis for low and medium temperature district heating systems. ► Different district heating network dimensioning methods are analyzed. ► Major exergy losses are identified in the district heating network and the in-house substations. ► Advantages to apply low temperature district heating are highlighted through exergy analysis. ► The influence of thermal by-pass on system exergy/energy performance is analyzed.

Described in an analysis of the cost to the Ministry of Health of providing district health services in Malawi, with particular emphasis on the district hospital. District resource allocation patterns were assessed by carefully disaggregating district costs by level of care and hospital department. A strikingly low proportion of district recurrent costs was absorbed by salaries and wages (27-39%, depending on the district) and a surprisingly high proportion by medical supplies (24-37%). The most expensive cost centre in the hospital was the pharmacy. A total of 27-39% of total recurrent costs were spent outside the hospital and 61-73% on hospital services. The secondary care services absorbed 40-58% of district recurrent costs. Unit costs by hospital department varied considerably by district, with one hospital being consistently the most expensive and another the cheapest. A total of 3-10 new outpatients could be treated for the average cost of 1 inpatient-day, while 34-55 could be treated for the average cost of 1 inpatient. The efficiency of hospital operations, the scope for redistributing resources districtwide, and the costing methodology are discussed.

Energy Neutral Districts in 2050. The Dutch Approach

Energy Technology Data Exchange (ETDEWEB)

Jablonska, B.; Roossien, B.; Ruijg, G.J.; Visser, H.; Bakker, E.J. [Energy research Centre of the Netherlands ECN, Petten (Netherlands); Willems, E. [Cauberg-Huygen Raadgevende Ingenieurs, Amsterdam (Netherlands)

According to the EPBD, from the end of 2020 on all new buildings should be built as nearly zero energy buildings. Instead of focusing on buildings only, a district approach to energy supply and consumption can be advantageous as regards the energy performance and economics. The potential of renewable energy technologies can be utilized to a larger extent while fewer energy generators are needed. An example is a so called energy-hub, in which exchange, conversion and seasonal storage of energy can lead to energy neutral districts before 2050. The Dutch study Transition in Energy and Process for a Sustainable District Development (Transep-DGO), financed largely by the AgentschapNL, has shown that this is possible. For energy neutral district development in 2050, six innovative energy concepts have been elaborated and the extent of energy neutrality in 2020, 2035 and 2050 calculated. Three concepts are based on an idea of an energy hub - bio hub, geo hub and a solar hub. Other concepts are all-electric, conventional and hydrogen concepts. Calculations show that implementation of each of the concepts can lead to energy neutral districts in 2050 or even earlier. When personal transport is included, energy neutrality in 2050 is not feasible. Based on the six general concepts, the most optimal energy concepts tailored for four Dutch cities have been elaborated as pilots, in close cooperation with municipality representatives. Solar hub has been dynamically simulated in order to show the added value of the exchange, conversion and storage of energy flows on a district scale. Energy Pattern Generator (EPG) has been applied for simulation of a virtual district with 1,000 dwellings of various categories. A solar hub with collective heat storage can reduce the demanded storage capacity by 26%, and the total required solar collector surface by 30% at maximum compared to individual seasonal heat storage capacity in dwellings that are not connected in an energy hub.

Reforming health service delivery at district level in Ghana: the perspective of a district medical officer.

Science.gov (United States)

Agyepong, I A

1999-03-01

Many countries in sub-Saharan Africa face the problem of organizing health service delivery in a manner that provides adequate quality and coverage of health care to their populations against a background of economic recession and limited resources. In response to these challenges, different governments, including that of Ghana, have been considering or are in the process of implementing varying degrees of reform in the health sector. This paper examines aspects of health services delivery, and trends in utilization and coverage, using routine data over time in the Dangme West district of the Greater Accra region of Ghana, from the perspective of a district health manager. Specific interventions through which health services delivery and utilization at district level could be improved are suggested. Suggestions include raising awareness among care providers and health managers that increased resource availability is only a success in so far as it leads to improvements in coverage, utilization and quality; and developing indicators of performance which assess and reward use of resources at the local level to improve coverage, utilization and quality. Also needed are more flexibility in Central Government regulations for resource allocation and use; integration of service delivery at district level with more decentralized planning to make services better responsive to local needs; changes in basic and inservice training strategies; and exploration of how the public and private sectors can effectively collaborate to achieve maximum coverage and quality of care within available resources.

analyses excess heat sources from the industrial sector and how they could be used for district heating. This method first allocates excess heat to single production units by introducing and validating a new approach. Spatial analysis of the heat sources and consumers are then performed to evaluate...... the potential for using them for district heating. In this way the theoretical potential of using the excess heat for covering the heating demand of buildings is determined. Through the use of industry specific temperature profiles the heat usable directly or via heat pumps is further found. A sensitivity...... analysis investigates the impact of future energy efficiency measures in the industry, buildings and the district heating grid on the national potential. The results show that for the case study of Denmark, 1.36 TWh of district heat could be provided annually with industrial excess heat from thermal...

2013-09-01

The Ppd-A1 genotype of 240 Japanese wheat cultivars and 40 foreign cultivars was determined using a PCR-based method. Among Japanese cultivars, only 12 cultivars, all of which were Hokkaido winter wheat, carried the Ppd-A1a allele, while this allele was not found in Hokkaido spring wheat cultivars or Tohoku-Kyushu cultivars. Cultivars with a photoperiod-insensitive allele headed 6.9-9.8 days earlier in Kanto and 2.5 days earlier in Hokkaido than photoperiod-sensitive cultivars. The lower effect of photoperiod-insensitive alleles observed in Hokkaido could be due to the longer day-length at the spike formation stage compared with that in Kanto. Pedigree analysis showed that 'Purple Straw' and 'Tohoku 118' were donors of Ppd-A1a and Ppd-D1a in Hokkaido wheat cultivars, respectively. Wheat cultivars recently developed in Hokkaido carry photoperiod-insensitive alleles at a high frequency. For efficient utilization of Ppd-1 alleles in the Hokkaido wheat-breeding program, the effect of Ppd-1 on growth pattern and grain yield should be investigated. Ppd-A1a may be useful as a unique gene source for fine tuning the heading time in the Tohoku-Kyushu region since the effect of Ppd-A1a on photoperiod insensitivity appears to differ from the effect of Ppd-B1a and Ppd-D1a.

Emplacement model of obsidian-rhyolite magma deduced from complete internal section of the Akaishiyama lava, Shirataki, northern Hokkaido, Japan

Science.gov (United States)

Wada, K.; Sano, K.

2016-12-01

Simultaneously explosive and effusive eruptions of silicic magmas has shed light on the vesiculation and outgassing history of ascending magmas in the conduit and emplacement model of obsidian-rhyolite lavas (Castro et al., 2014; Shipper et al, 2013). As well as the knowledge of newly erupted products such as 2008-2009 Chaitén and 2011-2012 Cordón Caule eruptions, field and micro-textural evidences of well-exposed internal structure of obsidian-rhyolite lava leads to reveal eruption processes of silicic magmas. The Shirataki monogenetic volcano field, 2.2 million year age, northern Hokkaido, Japan, contains many outcrops of obsidian and vesiculated rhyolite zones (SiO2=76.7-77.4 wt.%). Among their outcrops, Akaishiyama lava shows good exposures of internal sections from the top to the bottom along the Kyukasawa valley with thickness of about 190 meters, showing the symmetrical structure comprising a upper clastic zone (UCZ; 5m thick), an upper dense obsidian zone (UDO; 15m), an upper banded obsidian zone (UBO; 70-80m), a central rhyolite zone (CR; 65m), a lower banded obsidian zone (LBO; 15m), a lower dense obsidian zone (LDO; 20m), and a lower clastic zone (LCZ; 3m). The upper banded obsidian zone is characterized by existence of spherulite concentration layers with tuffisite veins and rhyolite enclaves. Spherulites consisting of albite, cristobalaite and obsidian glass, are clustered in the dense obsidian. Tuffisite veins show brecciated obsidians in tuffaceous matrix, showing an outgassing path during the emplacement of obsidian lava. Perpendicular dip of spherulite parallel rows indicates the banded zone itself was the domain of vent area. From the observation of these occurrences in the internal section and rock texture, we show the qualitative formation model of Shirataki obsidian-rhyolite lava.

Woodfuel procurement strategies of district heating plants

Roos, A.; Bohlin, F.; Hektor, B.; Hillring, B.

2003-01-01

Woodfuel use in the Swedish district heating sector increased significantly from 1985 to 1999. This study analysed strategies and considerations concerning woodfuel procurement in district heating plants. Priorities and concerns in the industry involved an increased woodfuel share, ambitions to create an environmental image, cost minimisation, awareness about the role of energy policies for fuel choice, improvement of woodfuel quality and the ambition to maintain a competitive woodfuel market with several suppliers. Factor analysis yielded five dimensions in the woodfuel procurement strategies among the district heating companies: (1) increased woodfuel use; (2) import; (3) spot market woodfuel purchases; (4) focus on refined woodfuels; and (5) using price only when deciding whether to use woodfuels or other fuels. Five clusters were defined along the three strategy dimensions (1)-(3). The clusters differed concerning size, experiences from the introduction of woodfuels, perceptions about woodfuels and strategies employed to date. This paper describes different strategies that the district heating companies apply on the woodfuel market. The conclusion is that policies should consider this diversity in procurement strategies, mitigate their negative side-effects and assist to make them cost-effective. (author)

Health care managers and personnel should be aware and literate of health information system in order to increase the efficiency and effectiveness in their organization. Since accurate, appropriate, precise, timely, valid information and interpretation of information is required and is the basis for policy planning and decision making in various levels of the organization. This study was conducted to assess the district health information system evolution in Iran according to WHO framework. This research is an applied, descriptive cross sectional study, in which a total of twelve urban and eight rural facilities, and the district health center at Falavarjan region were surveyed by using a questionnaire with 334 items. Content and constructive validity and reliability of the questionnaire were confirmed with correlation coefficient of 0.99. Obtained data were analyzed with SPSS 16 software and descriptive statistics were used to examine measures of WHO compliance. The analysis of data revealed that the mean score of compliance of district health information system framework was 35.75 percent. The maximum score of compliance with district health information system belonged to the data collection process (70 percent). The minimum score of compliance with district health information system belonged to information based decision making process with a score of 10 percent. District Health Information System Criteria in Isfahan province do not completely comply with WHO framework. Consequently, it seems that health system managers engaged with underlying policy and decision making processes at district health level should try to restructure and decentralize district health information system and develop training management programs for their managers.

Seto, K.; Katsuki, K.; Takeshi, S.

In the coastal area of the Sea of Okhotsk in the east part of Hokkaido located to subarctic zone, many brackish-water lakes are distributed. Lake Mokoto consist of organic mud with the lamination. The 09Mk-1C core at 2009. In the soft X-ray photograph, the cyclic lamina set is observed. The cyclic lamina set consists of low- and high-density lamina. According to the meteorological data in Abashiri region, the annually precipitation is high from August to September. Probably, the cyclic lamina set is formed by seasonal change of precipitation. In August 2016, it showed a precipitation of 425 mm which is about 4 times the average precipitation. In February 2017, the 10 cm class short core (17Mk-4SC core) was collected and the flood lamina was observed. Six layers showing different color were observed in top 6.5 cm. The first, third and fifth layers from the top are relatively light in color (L*value=17). The second, fourth and sixth layers are relatively dark in color (L*value=8). Thickness of the first to fourth layers is about 5 mm, but the thickness of the fifth layer reaches 4 cm. According to the observation of the soft X-ray photograph, the third and fifth layers were high-density lamina, and the others were low-density lamina. Because these layers were not observed in the 15Mk-3C core collected in March 2015, they were deposited after that. It is estimated that the third layer showing the high-density lamina is the sediment of the flood event in August 2016. This is supported by the fact that the total organic carbon (TOC) and total sulfur (TS) contents are diluted and the C/N ratio is relatively high value. Because this lamina is remarkable, it will be used as a future key bed. On the other hand, the fifth layer showing the high-density is a very thick. In this layer, the TS content is diluted and the C/N ratio is high, but the TOC content shows the highest value. This suggests that sediments with high TOC content flowed out from Mokoto River Basin. It has

2011-10-01

States and school districts nationwide have enacted policies targeting youth obesity, but many policies lack specific requirements or enforcement language. Geographic disparities in youth obesity could worsen if policies are weaker in areas with higher obesity prevalence. To determine if state or district policy strength varies with youth obesity prevalence across Census divisions. Policies in five domains related to nutrition and physical activity in schools were obtained from all states and nationally representative samples of 578 and 592 public school districts in the 2006-2007 and 2008-2009 school years, respectively. Policy language strength was rated on a 0-100 scale on both the state and district level. Regression models were used to determine if mean 2006-2007 strength scores, and changes in mean scores from 2006-2007 to 2008-2009, were associated with youth obesity prevalence across Census divisions. Analyses were conducted in 2010. State and district policies governing foods sold outside of school meal programs ("competitive foods") were stronger in 2006-2007 in the two divisions with the highest youth obesity prevalence (East South Central, West South Central). Furthermore, mean competitive food policy strength increased the most from 2006-2007 to 2008-2009 in these divisions. The West South Central had the weakest district physical education policies in 2006-2007, however, and was the only division in which average strength of district school meal policies decreased. State and districts in Census divisions with the highest youth obesity prevalence are taking steps to restrict competitive foods in schools, but many have not targeted other policy domains as aggressively.

Developing a district energy system in a competitive urban market

Energy Technology Data Exchange (ETDEWEB)

Mitola, J.P. [Unicom Thermal Technologies, Chicago, IL (United States)

1995-09-01

In two year`s time, Unicorn Thermal Technologies has grown into one of the largest district cooling systems of 25,000 tons with a 1996 plan to grow to 40,000 tons. This growth is attributed to the development and implementation of a marketing and sales plan based on thorough market research and innovative marketing and sales strategies, and the consistent implementation of those strategies. The beginning of the sales effort was focused around the company`s first district cooling facility, However, it quickly grew into a much broader vision as market acceptance increased. Although the district energy industry has often based its message on being a low cost energy provider, market research and early sales experience indicated that customers choose district cooling as a value added service. As customers began to reserve capacity in the first plant, the idea that district cooling is a value added service and not a commodity energy product was continually reinforced through marketing communications. Although this analysis is a review of developing a district energy system in a competitive urban market, it purposely avoids a long winded discussion of head to head competition.

Soederholm, Patrik; Warell, Linda

2011-01-01

The purpose of this paper is to analyse the possible effects of introducing TPA in district heating networks by identifying and scrutinizing a number of possible scenarios for increased competition. The analysis builds on a theoretical discussion of economic efficiency in district heating operations, and the possible impacts on consumer prices of a market opening. An important conclusion is that regulated TPA may have small positive effects on competition, and at the same time it can have a negative impact on the possibility to run the integrated district heating operations in a cost-effective manner. This conclusion stems in part from the observation that most district heating networks are local in scope. Moreover, district heating operations are highly interdependent in, for instance, that the level of the return temperature of the water will affect the efficiency of combined heat and power plants. For these reasons, the introduction of the so-called single-buyer model or, perhaps even more preferable, an extended and more transparent producer market could represent more efficient market designs. Moreover, in networks with clear natural monopoly characteristics an ex ante price regulation must be considered. - Research Highlights: →The paper analyses the possible effects of TPA in district heating networks. → Four possible scenarios for increased competition are identified and scrutinized. → A conclusion is that regulated TPA have only small positive effects on competition. → District heating operations are highly interdependent and separation can be costly.

Enhancing assertiveness in district nurse specialist practice.

Science.gov (United States)

Green, Julie

2016-08-02

District nurse (DN) care delivery has undergone substantial change in recent years due to changing demographics and service delivery demands that have called for a move of care delivery from secondary to primary care. The title District Nurse is recorded with the Nursing and Midwifery Council (NMC) on completion of the Specialist Practice Qualification in District Nursing (SPQ DN), which purports to be a 'transformational' course that prepares future caseload holders to manage their team and prioritise care delivery effectively. This article explores the need for assertiveness skills in this role in response to Australian research, and outlines the pedagogic interventions implemented during the SPQ DN course to enhance this skill. Assertiveness scores were monitored for the duration of the course and demonstrated a significant increase-a topic that is now the subject of a future, funded study.

Guidelines for District Heating Substations

Energy Technology Data Exchange (ETDEWEB)

2009-07-15

The present guidelines contain a set of recommendations focusing on planning, installation, use and maintenance of district heating (DH) substations within district heating systems throughout Europe. The recommendations were developed in order to enable readers to develop well-functioning substations and an effective heat and domestic warm water delivery. These guidelines are intended to give the most effective overall solutions for various parts of the customer installation. The guidelines are not meant to specify the different components of the substation such as meters or heat exchangers. The guidelines deal with a wide variety of issues concerning both present systems of today and district heating systems of the future. Specific handling and maintenance recommendations are mainly focused on present modern systems but are also intended to cover the future situation as much as is feasible. For this reason, certain existing systems are not dealt with in these guidelines. For instance, these guidelines do not cover steam systems, systems with temperatures exceeding 110 deg C and pressure levels above 1.6 MPa. The guidelines include a chapter on the heat meter, as the meter and especially the meter installation is always installed simultaneously with the rest of the substation. These guidelines aim to provide best-practice and easy-to-handle recommendations for: - those who are responsible for relations between district heating utilities and customers; - those who own or maintain a building connected to the district heating network; - those who manufacture, plan, purchase, test and install substations. These guidelines do not deal with investment or cost aspects, but in general, Euroheat and Power recommends looking at the lifetime cost of all components of the substation, instead of investment costs alone. An example of this is provided in Chapter 7.8. The Guidelines were developed based on the most optimal operating principles of substations and meters

Water supply network district metering theory and case study

CERN Document Server

Di Nardo, Armando; Di Mauro, Anna

2013-01-01

The management of a water supply network can be substantially improved defining permanent sectors or districts that enhances simpler water loss detection and pressure management. However, the water network partitioning may compromise water system performance, since some pipes are usually closed to delimit districts in order not to have too many metering stations, to decrease costs and simplify water balance. This may reduce the reliability of the whole system and not guarantee the delivery of water at the different network nodes. In practical applications, the design of districts or sectors is generally based on empirical approaches or on limited field experiences. The book proposes a design support methodology, based on graph theory principles and tested on real case study. The described methodology can help water utilities, professionals and researchers to define the optimal districts or sectors of a water supply network.

District Heating Expansion Potential with Low-Temperature and End-Use Heat Savings

DEFF Research Database (Denmark)

Nielsen, Steffen; Grundahl, Lars

2018-01-01

District heating has the potential to play a key role in the transition towards a renewable energy system. However, the development towards reduced heat demands threatens the feasibility of district heating. Despite this challenge, opportunity exists in the form of fourth generation district...... heating, which operates at lower temperatures and enables better renewable integration. This article investigates this challenge by examining the district heating potential within three scenarios: The first is a reference scenario with current heat demand and temperatures, the second includes heat demand...... costs. The models are applied using an example case of The Northern Region of Denmark. The article concludes that the district heating potential is highest in the reference scenario. When heat savings are introduced, district heating expansions, in most cases, will not be feasible. Introducing low...

Hirasawa, K; Shibata, J; Yamamura, K

1989-07-01

We made a clinical and statistical evaluation of the occurrence of acute myocardial infarction with respect to the relation between its occurrence and the meterology of the cold inland area of Hokkaido (the Kamikawa Basin) over a period of 10 years (1976-1985). A total of 581 cases were studied. Monthly fluctuation of incidence was not found to be statistically significant. A cold period in the Kamikawa Basin was defined in this study as the period when ordinary mean atmospheric temperatures were below 0 degree C (from 7 Nov. to 16 Apr.). Canonical discriminant analysis was applied to 10 meterological factors between the days with occurrences and those without occurrences (245 days vs 245 days) in the cold periods of the investigated 10 years, and between the days with outdoor occurrences and those without occurrences (37 days vs 37 days). In order to compare the regional difference, this analysis was done on the same 10 factors for the cold periods over 3 years in Yamagata (46 days vs 46 days). The F values of 0.0003, 0.0155 and 0.0098 respectively in the above 3 analyses were small (much less than F 1(9) (0.25) = 1.51). A circadian rhythm of 2 cycles/day was recognized concerning the time of occurrence by power spectral analysis of the data of 562 patients for whom the time of the onset of myocardial infarction was known. Subdividing the patients into 2 groups according to physical activity just before the occurrence, the group who experienced an occurrence at rest showed a rhythm of 1 cycle/day, and the group who experienced an occurrence on effort showed a rhythm of 2 cycles/day. Therefore, the 10 meterological factors could not discriminate the probabilities between the days with occurrences and the days without occurrences of myocardial infarction in the cold periods. On the other hand, it was suggested that biological intrinsic rhythm participates in triggering the occurrence of myocardial infarction.

Kılkış, Şiir

2014-01-01

Highlights: • Östra Sala backe is analyzed as a pilot district for the net-zero exergy target. • An analysis tool is developed for proposing an energy system for Östra Sala backe. • A total of 8 different measures are included and integrated in the energy system. • The exergy produced on-site is 49.7 GW h, the annual exergy consumed is 54.3 GW h. • The average value of the level of exergy match in the supply and demand is 0.84. - Abstract: The Rational Exergy Management Model (REMM) provides an analytical model to curb primary energy spending and CO 2 emissions by means of considering the level of match between the grade/quality of energy resources (exergy) on the supply and demand sides. This model is useful for developing forward-looking concepts with an energy systems perspective. One concept is net-zero exergy districts, which produce as much energy at the same grade or quality as consumed on an annual basis. This paper analyzes the district of Östra Sala backe in Uppsala Municipality in Sweden as a pilot, near net-zero exergy district. The district is planned to host 20,000 people at the end of four phases. The measures that are considered include an extension of the combined heat and power based district heating and cooling network, heat pumps driven on renewable energy, district heating driven white goods, smart home automation, efficient lighting, and bioelectricity driven public transport. A REMM Analysis Tool for net-zero exergy districts is developed and used to analyze 5 scenarios based on a Net-Zero Exergy District Option Index. According to the results, a pilot concept for the first phase of the project is proposed. This integrates a mix of 8 measures considering an annual electricity load of 46.0 GW h e and annual thermal load of 67.0 GW h t . The exergy that is produced on-site with renewable energy sources is 49.7 GW h and the annual exergy consumed is 54.3 GW h. The average value of the level of match between the demand and supply of

To study the association between the number of area-level and individual-level social participation items and cognitive function in the community-dwelling older populations of three towns in Hokkaido, Japan. A survey on the frequency of social participation was mailed to those in the Japan Gerontological Evaluation Study 2013 who were aged ≥65 years, were not certified as needing long-term care, and lived in Higashikawa, Higashikagura, or Biei. A subset of participants aged 70-74 years completed the Japanese version of the Montreal Cognitive Assessment in a home visit survey. Both the area-level and individual-level social participation and demographic information were obtained on the self-administered questionnaire. A multilevel analysis using a generalized linear mixed-effects model was used to examine the association between variables in the area-level and individual-level social participation items and cognitive function. Out of 4042 respondents, data from 2576 were used in the area-level analysis. Of those, 180 were aged 70-74 years and completed the home visit survey for the individual-level analysis. A greater number of higher social participation items at the individual level was associated with higher cognitive function scores after adjusting for area-level social participation variables and confounders (regression coefficient: 0.19; 95% confidence interval: 0.03, 0.35). There were no significant associations between area-level social participation item averages and individual-level cognitive function scores. Older populations participating in many kinds of social activities exhibited preserved cognitive function even after adjusting for area-level social participation variables.

The Innovative Concept of Cold District Heating Networks: A Literature Review

Directory of Open Access Journals (Sweden)

Marco Pellegrini

2018-01-01

Full Text Available The development of sustainable and innovative solutions for the production and supply of energy at district level is nowadays one of the main technical challenges. In the past, district heating and cooling networks aimed to achieve greater energy efficiency through the centralization of the energy production process but with relevant losses related to heat transport. Moving towards a higher share of renewables and lower demand of primary energy requires redesign of the energy district networks. The novel concept of cold district heating networks aims to combine the advantages of a centralized energy distribution system with low heat losses in energy supply. This combined effect is achieved through the centralized supply of water at relatively low temperatures (in the range 10–25 °C, which is then heated up by decentralized heat pumps. Moreover, cold district heating networks are also very suitable for cooling delivery, since cold water supplying can be directly used for cooling purposes (i.e., free cooling or to feed decentralized chillers with very high energy efficiency ratio. This paper provides a preliminary literature review of existing cold district heating networks and then qualitatively analyses benefits and drawbacks in comparison with the alternatives currently used to produce heat and cold at district level, including the evaluation of major barriers to its further development.

In the recent years many studies of how Denmark can be fossil free by 2050 it is agreed that district heating will play a crucial role. District heating is an important factor of phasing out fossil fuels in an energy-and cost-effective way. But the future energy supply without fossil fuels poses new requirements for district heating. In the future, district heating shall provide energy for low-energy houses, have low distribution losses and use a variety of heat sources such as geothermal, solar, waste, surplus heat, CHP and various biomass con-version processes. In addition, it must all be done in an energy efficient way and in an active interaction with production of electricity and electricity consumption and, through integration of electricity from wind, solar and wave power. Low temperature, use of heat pumps and the interaction with electricity and biomass will be keywords. It is not only in Denmark we will need an active development of future technologies and systems. Large parts of Europe and many other parts of the world need the same development, and today Denmark has a significant export in the market - an export that has risen sharply, despite the recent economic recession. There is thus a double need to actively promote the development of future district heating technologies. We will partly need the technology development to realize the goal of a fossil free society and secondly because it is necessary to maintain and expand the export. This report contains a number of proposals for concrete actions - a roadmap for the development of district heating. The project is anchored at the District Energy Development Center that will work for an implementation of the concrete project ideas after the project completion. There is a need to increase the activity level for development of district heating. There is therefore a need to ensure financing of this development. We suggest that this can be done by creating an opportunity for a more sustained funding, for

Person-centred communication for emotional support in district nursing: SAGE and THYME model.

Science.gov (United States)

Griffiths, Jane

2017-12-02

Patients on district nursing caseloads have multiple physical morbidities, and related emotional concerns. District nurses are ideally placed to assess and meet patients' emotional needs but in increasingly stretched workplaces, it is difficult to find time. There is also evidence that district nurses sometimes believe they lack skills to address patients' concerns. Traditional communication skills training is useful for encouraging patients to open up about their concerns, but less helpful at finding workable solutions. District nurses can be afraid to open a 'can of worms' of concerns that they are unable to deal with. SAGE and THYME is a person-centred, evidence-based communication skills model that addresses district nurses' concerns about time and skills. It provides a structure for conversations about concerns, and empowers patients to work with district nurses to find solutions. Research suggests that it is a promising model for district nursing practice.

1998-04-01

The main objective of the project has been to assist Viljandi Municipality with the rehabilitation of their district heating system, and thereby to support the positive development of the district heating system in Viljandi to a more energy efficient and rational system and to achieve a significantly decrease in the pollution from the production of heat energy in Viljandi. The project has also included technical assistance to Viljandi DH company, in order to make them capable of operation and maintaining of the new substations, and also training of the local operational staff for operation of the complete district heating system. Viljandi is a county and is centrally located in Estonia, which makes Viljandi very suitable as recipient for a demonstration project. One important objective was the projects significantly positive environmental impact in reduction of the generated emissions of CO 2 , NO x and SO 2 , as the project includes installation of more efficient energy systems and supply of heat from the 2 existing district heating plants (both are partly fired with wood chips) instead of heating by very old and worn-out coal fired boilers and inexpedient designed substations with the present operational conditions.

Full Text Available Forests play an important role in the terrestrial carbon balance, with most being in a carbon sequestration stage. The net carbon releases that occur result from forest disturbance, and windthrow is a typical disturbance event affecting the forest carbon balance in eastern Asia. The CO2 flux has been measured using the eddy covariance method in a deciduous broadleaf forest (Japanese white birch, Japanese oak, and castor aralia in Hokkaido, where incidental damage by the strong Typhoon Songda in 2004 occurred. We also used the biometrical method to demonstrate the CO2 flux within the forest in detail. Damaged trees amounted to 40 % of all trees, and they remained on site where they were not extracted by forest management. Gross primary production (GPP, ecosystem respiration (Re, and net ecosystem production were 1350, 975, and 375 g C m−2 yr−1 before the disturbance and 1262, 1359, and −97 g C m−2 yr−1 2 years after the disturbance, respectively. Before the disturbance, the forest was an evident carbon sink, and it subsequently transformed into a net carbon source. Because of increased light intensity at the forest floor, the leaf area index and biomass of the undergrowth (Sasa kurilensis and S. senanensis increased by factors of 2.4 and 1.7, respectively, in 3 years subsequent to the disturbance. The photosynthesis of Sasa increased rapidly and contributed to the total GPP after the disturbance. The annual GPP only decreased by 6 % just after the disturbance. On the other hand, the annual Re increased by 39 % mainly because of the decomposition of residual coarse-wood debris. The carbon balance after the disturbance was controlled by the new growth and the decomposition of residues. The forest management, which resulted in the dead trees remaining at the study site, strongly affected the carbon balance over the years. When comparing the carbon uptake efficiency at the study site with that at others, including those with various kinds

2001-01-01

Maintenance of the technical operation conditions of district heating is the main requirement of community to the district heating business. Infrastructure of district heating, including the heat generation and distribution plants, equipment and devices, requires relatively large investments. Total process from fuel purchase to heat delivery does not occur in a closed limited area, but it penetrates the total market area (heat distribution network) and even larger via fuel purchase and transport. E.g. the fuels are combustible and might explode. Oil-spills into the environment may have catastrophic effects. Large leakage of hot district heating water is both environmentally hazardous and forms also a health hazard, and they stop the delivery of district heat. Dominant position on the markets is also followed closely by the authorities. On the other hand competition with other heating forms require efficient operation. The author reviews in the article the basics of risk management, and especially in the district heating business. The risk management process is discussed in the risk analysis and determination of the significance of the risks, the effects of realization of the risks, planning of the measures to be taken to avoid risks, and preparations against the risks

This thesis describes the conditions for district heating in the Republic of Korea at the turn of the year 1994-95. It is based on a study made in Seoul at Korea District Heating Corporation, which is the largest district heating utility in Korea. The substations were particularly studied. District heating was introduced in Korea in the 80s because of the environmental advantages. KHDC was established in 1985 and in 1994 they provided 340 000 households with district heating. By the year of 2001 KDHC plans to supply 45% of the heating in Seoul with its 12 million inhabitants. KDHC receives most of its thermal energy from combined heat and power plants that use natural gas as fuel. In 1991 KDHC initiated a collaboration with Ekono of Finland to develop more advanced technology in Korea. Therefore the Finnish standard, which is similar to Swedish standard, has left it`s mark on the Korean district heating technology. Typical for the Korean substation is that the heat exchangers are connected in parallel in only one step. KDHC:s expansion will, within a couple of years, help to make Korea one of the leading countries in modern district heating. 9 refs, 3 figs, 2 tabs

Viscoelastic crustal deformation by magmatic intrusion: A case study in the Kutcharo caldera, eastern Hokkaido, Japan

Science.gov (United States)

Yamasaki, Tadashi; Kobayashi, Tomokazu; Wright, Tim J.; Fukahata, Yukitoshi

2018-01-01

Geodetic signals observed at volcanoes, particularly their temporal patterns, have required us to make the correlation between the surface displacement and magmatic process at depth in terms of viscoelastic crustal rheology. Here we use a parallelized 3-D finite element model to examine the response of the linear Maxwell viscoelastic crust and mantle to the inflation of a sill in order to show the characteristics of a long-term volcano deformation. In the model, an oblate-spheroidal sill is instantaneously or gradually inflated in a two-layered medium that consists of an elastic layer underlain by a viscoelastic layer. Our numerical experiments show that syn-inflation surface uplift is followed by post-inflation surface subsidence as the viscoelastic substrate relaxes. For gradual inflation events, the magnitude of inflation-induced uplift is reduced by the relaxation, through which the volume of a magma inferred by matching the prediction of an elastic model with observed surface uplift could be underestimated. For a given crustal viscosity, sill depth is the principal factor controlling subsidence caused by viscoelastic relaxation. The subsidence rate is highest when the inflation occurs at the boundary between the elastic and the viscoelastic layers. The mantle viscosity has an insignificant impact unless the depth of the inflation is greater than a half the crustal thickness. We apply the viscoelastic model to the interferometric synthetic aperture radar (InSAR) data in the Kutcharo caldera, eastern Hokkaido, Japan, where the surface has slowly subsided over a period of approximately three years following about a two-year period of inflation. The emplacement of a magmatic sill is constrained to occur at a depth of 4.5 km, which is significantly shallower than the geophysically imaged large-scale magma chamber. The geodetically detected deformation in the caldera reflects the small-scale emplacement of a magma that ascended from the deeper chamber, but not the

Li, Peifeng; Nord, Natasa; Ertesvåg, Ivar Ståle; Ge, Zhihua; Yang, Zhiping; Yang, Yongping

2015-01-01

Highlights: • Simulation of power plant, district heating network and heat users in detail and integrated. • Coupled calculation and analysis of the heat and pressure losses of the district heating network. • District heating is not preferable for very low heat load due to relatively high heat loss. • Lower design supply temperatures of the district heating network give higher system efficiency. - Abstract: Many studies have been carried out separately on combined heat and power and district heating. However, little work has been done considering the heat source, the district heating network and the heat users simultaneously, especially when it comes to the heating system with large-scale combined heat and power plant. For the purpose of energy conservation, it is very important to know well the system performance of the integrated heating system from the very primary fuel input to the terminal heat users. This paper set up a model of 300 MW electric power rated air-cooled combined heat and power plant using Ebsilon software, which was validated according to the design data from the turbine manufacturer. Then, the model of heating network and heat users were developed based on the fundamental theories of fluid mechanics and heat transfer. Finally the combined heat and power based district heating system was obtained and the system performances within multiscale scope of the system were analyzed using the developed Ebsilon model. Topics with regard to the heat loss, the pressure drop, the pump power consumption and the supply temperatures of the district heating network were discussed. Besides, the operational issues of the integrated system were also researched. Several useful conclusions were drawn. It was found that a lower design primary supply temperature of the district heating network would give a higher seasonal energy efficiency of the integrated system throughout the whole heating season. Moreover, it was not always right to relate low design

North–South debate on district heating: Evidence from a household survey

Guo, Jin; Huang, Ying; Wei, Chu

2015-01-01

There has been a long debate on whether South China should supply district heating for the residential sector, a system that is widely used in North China. The major concern is that it may further accelerate China's energy demand. Using a unique urban household level dataset, the China Residential Energy Consumption Survey (CRECS), we investigate residential energy consumption for heating and examine the energy intensity and energy cost of distributed heating in South China and district heating in North China during the 2012 heating season. Our results show that the total energy consumption for distributed heating system users in southern cities is significantly lower than for users of district heating systems in northern cities. However, when accounting for the heating area and heating season, the distributed heating households in the South consumed 32% more energy and paid 189% higher cost per unit area and per hour, but had lower comfort than district heating users in the North. These findings suggest promoting the district heating market in appropriate areas in South China. This not only can improve residential welfare, but also can indirectly reduce energy consumption and financial burdens. - Highlights: • The debate on whether Southern China apply district heating is present. • The household data in 2012 is used to compare the energy efficient and cost. • South resident use more energy and higher cost but less comfort than North. • Government should not prevent the district heating market.

Economic and environmental benefits of converting industrial processes to district heating

2014-01-01

Highlights: • The potential for converting industrial processes to district heating is analyzed. • The study includes 83 manufacturing companies in three Swedish counties. • The energy costs for the companies decrease after the conversions. • The conversion opens up for a reduction of global greenhouse gas emissions. • CHP plants in the local district heating system are better utilized. - Abstract: The aim of this study was to analyse the possibilities of converting industrial processes from electricity and fossil fuels to district heating in 83 companies in three Swedish counties. Effects on the local district heating systems were explored, as well as economic effects and impacts on global emissions of greenhouse gases. The study was conducted considering two different energy market conditions for the year 2030. The results show that there is a potential for increasing industrial district heating use in all analysed counties. The greatest potential regarding percentage is found in Jönköping, where the annual district heating use in the manufacturing companies could increase from 5 GW h to 45 GW h. The annual industrial district heating use could increase from 84 GW h to 168 GW h in Östergötland and from 14 GW h to 58 GW h in Västra Götaland. The conversion of the industrial production processes to district heating would lead to district heating demand curves which are less dependent on outdoor temperature. As a result, the utilization period of the base load plants (above all of the combined heat and power plants) would be prolonged; this would decrease district heating production costs due to the increased income from the electricity production. The energy costs for the industrial companies decrease after the conversions as well. Furthermore, the increased electricity production in the combined heat and power plants, and the decreased electricity and fossil fuel use in the industrial sector opens up a possibility for a reduction of global

Innovative and sustainable strategies to strengthen districts and other sub-national health systems and management are urgently required to reduce child mortality. Although highly effective evidence-based and affordable child survival interventions are well-known, at the district level, lack of data, motivation, analytic and planning capacity often impedes prioritization and management weaknesses impede implementation. The Community and District Empowerment for Scale-up (CODES) project is a complex management intervention designed to test whether districts when empowered with data and management tools can prioritize and implement evidence-based child survival interventions equitably. The CODES strategy combines management, diagnostic, and evaluation tools to identify and analyze the causes of bottlenecks to implementation, build capacity of district management teams to implement context-specific solutions, and to foster community monitoring and social accountability to increase demand for services. CODES combines UNICEF tools designed to systematize priority setting, allocation of resources and problem solving with Community dialogues based on Citizen Report Cards and U-Reports used to engage and empower communities in monitoring health service provision and to demand for quality services. Implementation and all data collection will be by the districts teams or local Community-based Organizations who will be supported by two local implementing partners. The study will be evaluated as a cluster randomized trial with eight intervention and eight comparison districts over a period of 3 years. Evaluation will focus on differences in uptake of child survival interventions and will follow an intention-to-treat analysis. We will also document and analyze experiences in implementation including changes in management practices. By increasing the District Health Management Teams' capacity to prioritize and implement context-specific solutions, and empowering communities to

Improved district heating substation efficiency with a new control strategy

International Nuclear Information System (INIS)

Gustafsson, Jonas; Delsing, Jerker; Deventer, Jan van

2010-01-01

In this paper, we describe a new alternative control approach for indirectly connected district heating substations. Simulations results showed that the new approach results in an increased ΔT across the substation. Results were obtained for both ideal and non-ideal operation of the system, meaning that less water must be pumped through the district heating network, and a higher overall fuel efficiency can be obtained in the district heating power plants. When a higher fuel efficiency is achieved, the usage of primary fuel sources can be reduced. Improved efficiency also increases the effective heat transfer capacity of a district heating network, allowing more customers to be connected to an existing network without increasing the heating plant or network capacity. Also, if combined heat and power plants are used to produce the heat, the increased ΔT will result in a further improved overall fuel efficiency, as more electricity can be produced with colder cooling water. The idea behind the new control method is to consider the temperature of the water supplying the district heating substation with heat, often referred to as the primary supply temperature. This represents a logical next step, as currently, the only parameter generally taken into account or measured when controlling the temperature level of the radiator circuit is the local outdoor temperature. In this paper we show how the primary supply temperature together with thermodynamic knowledge of the building can be used to maximize the ΔT across the district heating substation.

Automated vehicles (AVs) are increasingly being discussed as the basis for on-demand mobility services, introducing a new paradigm in which a fleet of AVs displaces private automobiles for day-to-day travel in dense activity districts. This paper examines a concept to displace privately owned automobiles within a region containing dense activity generators (jobs, retail, entertainment, etc.), referred to as an automated mobility district (AMD). This paper reviews several such districts, including airports, college campuses, business parks, downtown urban cores, and military bases, with examples of previous attempts to meet the mobility needs apart from private automobiles, some with automated technology and others with more traditional transit-based solutions. The issues and benefits of AMDs are framed within the perspective of intra-district, inter-district, and border issues, and the requirements for a modeling framework are identified to adequately reflect the breadth of mobility, energy, and emissions impact anticipated with AMDs

2018-06-01

Schools are in a unique position to meet the mental and behavioral health needs of children and adolescents because approximately 95% of young people aged 7-17 years attend school. Little is known, however, about policies related to counseling, psychological, and social services staffing in school districts. This study analyzed the prevalence of such policies in public school districts in the U.S. Data from four cycles (2000, 2006, 2012, and 2016) of the School Health Policies and Practices Study, a national survey periodically conducted to assess policies and practices for ten components of school health, were analyzed in 2017. The survey collected data related to counseling, psychological, and social services among nationally representative samples of school districts using online or mailed questionnaires. Sampled districts identified respondents responsible for or most knowledgeable about the content of each questionnaire. The percentage of districts with a district-level counseling, psychological, and social services coordinator increased significantly from 62.6% in 2000 to 79.5% in 2016. In 2016, 56.3% of districts required each school to have someone to coordinate counseling, psychological, and social services at the school. Fewer districts required schools at each level to have a specified ratio of counselors to students (16.2% for elementary schools, 16.8% for middle schools, and 19.8% for high schools), and the percentage of districts with these requirements has decreased significantly since 2012. Increases in the prevalence of district-level staffing policies could help increase the quantity and quality of counseling, psychological, and social services staff in schools nationwide, which in turn could improve mental and behavioral health outcomes for students.

Public funding of health at the district level in Indonesia after decentralization-sources, flows and contradictions.

Science.gov (United States)

Heywood, Peter; Harahap, Nida P

2009-04-16

During the Suharto era public funding of health in Indonesia was low and the health services were tightly controlled by the central government; district health staff had practically no discretion over expenditure. Following the downfall of President Suharto there was a radical political, administrative and fiscal decentralization with delivery of services becoming the responsibility of district governments. In addition, public funding for health services more than doubled between 2001 and 2006. It was widely expected that services would improve as district governments now had both more adequate funds and the responsibility for services. To date there has been little improvement in services. Understanding why services have not improved requires careful study of what is happening at the district level. We collected information on public expenditure on health services for the fiscal year 2006 in 15 districts in Java, Indonesia from the district health offices and district hospitals. Data obtained in the districts were collected by three teams, one for each province. Information on district government revenues were obtained from district public expenditure databases maintained by the World Bank using data from the Ministry of Finance. The public expenditure information collected in 15 districts as part of this study indicates district governments are reliant on the central government for as much as 90% of their revenue; that approximately half public expenditure on health is at the district level; that at least 40% of district level public expenditure on health is for personnel, almost all of them permanent civil servants; and that districts may have discretion over less than one-third of district public expenditure on health; the extent of discretion over spending is much higher in district hospitals than in the district health office and health centers. There is considerable variation between districts. In contrast to the promise of decentralization there has been

For the purpose of conserving energy and reducing greenhouse gas, a survey is conducted for district heating facilities of the Khimki district and Voskresensk district in Moscow and for their heat supply networks. Four boilers existing at the Khimki district are all to be replaced by natural gas turbine centralized cogeneration plants, and four boilers existing at the Voskresensk district are all to be replaced by natural gas turbine cogeneration facilities. These projects are designated as Case 1 and Case 2, different from each other in terms of power generation capability and heat supply scale. As for investment, a total of 267-million dollars will be necessary for Case 1, and 208-million dollars for Case 2. As for energy conservation, energy will be saved by approximately 2.8-million tons in total in terms of oil in Case 1, and approximately 2-million tons in terms of oil in Case 2. As for greenhouse gas reduction, there will be a reduction of approximately 6.8-million tons in terms of CO2 in Case 1, and a reduction of approximately 4.9-million tons in terms of CO2 in Case 2.

This thesis, which is the second part of two, analyses the consumption pattern and the conditions for district heating in the Republic of Korea at the turn of the year 1994-95. It is based on a study made in Seoul at Korea District Heating Corporation which is the largest district heating utility in Korea. District heating was introduced in the 80s because of the environmental advantages. In 1994 KDHC provided 340 000 households with district heating. KDHC receives most of its thermal energy from combined heat and power plants which use natural gas as fuel. One substation was chosen for the investigation and temperature, flow, and pressure were measured. A typical Korean substation has heat exchangers connected in parallel in only one step and the apartment complexes use floor heating for internal heating. The space heating load shows a linear relation to the outdoor temperature. The hot tap-water consumption shows a highly varying pattern with peak loads in the morning and evening. There were also an oscillating pattern for some of the temperatures and flows caused by poor regulation. DH suits very well to Korea with its climate and the overpopulated cities. KDHC:s expansion will help to make Korea one of the leading countries in modern district heating. 10 refs, 36 figs, 11 tabs

Bisphenol A (BPA) is widely used and BPA exposure is nearly ubiquitous in developed countries. While animal studies have indicated adverse health effects of prenatal BPA exposure including reproductive dysfunction and thyroid function disruption possibly in a sex-specific manner, findings from epidemiologic studies have not been enough to prove these adverse effects. Given very limited research on human, the aim of this study was to investigate associations between cord blood BPA levels and reproductive and thyroid hormone levels of neonates and whether associations differed by neonate sex. The study population included 514 participants of the Hokkaido study recruited from 2002 to 2005 at one hospital in Sapporo, Japan. The BPA level in cord blood was determined by ID-LC/MS/MS, and the limit of quantification was 0.040 ng/ml. We measured nine types of reproductive hormone levels in cord blood, and thyroid hormone levels were obtained from neonate mass screening test data. There were 283 subjects, who had both BPA and hormone levels measurements, included for the final analyses. The geometric mean of cord blood BPA was 0.051 ng/ml. After adjustment, BPA level was negatively associated with prolactin (PRL) (β = -0.38). There was an interaction between infant sex and BPA levels on PRL; a weak negative association was found in boys (β = -0.12), whereas a weak positive association was found in girls (β = 0.14). BPA level showed weak positive association with testosterone, estradiol, and progesterone levels in boys. No association was found between BPA and thyroid hormone levels. Our findings suggested that fetal BPA levels might be associated with changes in certain reproductive hormone levels of neonates in a sex-specific manner, though further investigations are necessary.

This report is the final documentation for the research project 'District heating prices in a liberalised energy market - benchmarking the production of combined heat and power'. The project compares activities for almost 300 companies, members of the Danish District Heating Society. The main aim of the analyses has been to uncover the saving potential by comparing each individual company to the most efficient companies in the sector. The variable costs have been studied, amounting to almost 7 billion Danish kroner a year, and the analyses found saving potential ranging from 5% to 60% dependent on the expectations to flexibility assigned to the individual companies. The data used are not available for the public as they exceed the Danish District Heating Society's annual statistics. (BA)

Utilization of straw in district heating and CHP plants

International Nuclear Information System (INIS)

Nikolaisen, L.

1993-01-01

In Denmark 64 straw-fired district heating plants and 6 decentral CHP plants have been built since 1980 which are completely or partly straw-fired. The annual straw consumption in the district heating plants is 275,000 tons and in the decentral plants about 200,000 tons. The size of the district heating plants amounts to 0.5 MW - 10 MW and that of the CHP plants to 7 MW - 67 MW heat flow rate. Either whole bales or cut/scarified straw is used for firing. Hesston bales of about 450 kg control the market. The Centre of Biomass Technology is an activity supported 100 % by the Danish Energy Agency with the purpose of increasing the use of straw and wood in the energy supply (orig.)

Promoting Children's and Adolescents' Social and Emotional Development: District Adaptations of a Theory of Action.

Science.gov (United States)

Kendziora, Kimberly; Osher, David

2016-01-01

This article contributes to the broader discussion of promotion, prevention, and intervention in child and adolescent mental health by describing implementation and early outcomes of an 8-school district demonstration project aimed at making the promotion of social and emotional learning a systemic part of school districts' practice. Eight districts are 2-3 years in to their participation in the 6-year project. The districts are large, are predominantly urban, and serve many students who are at disadvantage. The evaluation involved collection of qualitative data to measure the degree to which the districts realized the goals established in the initiative's theory of action, as well as school climate data, extant student records, and surveys of students' social and emotional competence. To date, results show that districts have followed highly individual pathways toward integrating social and emotional learning systemically, and all have made progress over time. Although school-level implementation remains at moderate levels, 2 districts in which we could examine school climate showed gains from preinitiative years. Four of 6 measured districts showed improvement in social and emotional competence for students in Grade 3, and achievement and discipline showed overall improvements across all districts. Overall findings show that implementation of the initiative's theory of action by school districts is feasible, even in times of budgetary stress and leadership turnover. This establishes the potential for school districts to serve as a lever of change in the promotion of students' social and emotional development and mental wellness.

District heating

Hansen, L.

1993-01-01

The environmental risks and uncertainties of a high-energy future are disturbing and give rise to several reservations concerning the use of fossil fuels. A number of technologies will help to reduce atmospheric pollution. In Denmark special importance is attached to the following: Energy conservation. Efficient energy conversion. Renewable energy sources. District heating, combined production of heat and power. Many agree that district heating (DH), produced by the traditional heat-only plant, and combined heat and power (CHP) have enormous potential when considering thermal efficiency and lowered environmental impacts: The basic technology of each is proven, it would be relatively simple to satisfy a substantial part of the energy demand, and their high efficiencies mean reduced pollution including greenhouse gas emissions. This is especially important in high population density areas - the obviously preferred sites for such energy generation. Compared with individual heating DH can provide a community with an operationally efficient and most often also an economically competitive heat supply. This is particularly true under the circumstances where the DH system is supplied from CHP plants. Their use results in very substantial improvements in overall efficiency. Further environmental improvements arise from the reduced air pollution obtainable in reasonably large CHP plants equipped with flue gas cleaning to remove particles, sulphur dioxide, and nitrogen acids. As a consequence of these considerations, DH plays an important role in fulfilling the space and water heating demand in many countries. This is especially the case in Denmark where this technology is utilised to a very great extent. Indeed, DH is one of the reasons why Denmark has relatively good air quality in the cities. (au)

Marcin Salamaga

2013-11-01

Full Text Available Purpose of the article: Regional development includes qualitative changes in economy (e.g. in production, investments, employment as well as qualitative changes (regarding the structure of economy and society, changes in the environment. The research of regional development is important and necessary in order to make appropriate decisions at the regional and local level. The main purpose of the article is comparative analysis of districts in the Lesser Poland Voivodship in the area of economic, social and ecological development. Scientific aim: The scientific aims of paper are verifying the hypothesis concerning eco-development and forecasting the level of regional development in districts of Lesser Poland Voivodship. Methodology/methods: In the research of regional development the quality index of economic, social and ecological development has been proposed which has been calculated on the basis of a certain aggregation of the results of the Principal Component Analysis made on the correlation matrix of standardised variables being the components of the index. Forecasts of the regional development level in districts were calculated with the use of different econometric models as linear model, exponential model, or power model. Findings: The findings prove that the Lesser Poland Voivodship is characterised by considerable disproportions in regional development. The most favourable conditions for economic and social development are in the districts with large city agglomerations as well as extensive municipality infrastructure and transport infrastructure. The presented results demonstrate that the majority of districts have not exhibited a constant tendency to changes in the positions in successive ranking lists in terms of the economic, social and ecological development. The positions occupied by most districts are generally stable and have not changed considerably in the examined period. Conclusions: The research has confirmed the negative

International Nuclear Information System (INIS)

Metke, E.; Skvarka, P.

1984-01-01

Technical and economical aspects of district heating by the electricity generating nuclear plants in Czechoslovakia are discussed. As a first stage of the project, 240 MW thermal power will be supplied using bleeding lines steam from the B-2 nuclear power plant at Jaslovske Bohunice to heat up water at a central station to 130 grad C. The maximal thermal power that can be produced for district heating by WWER type reactors with regular condensation turbines is estimated to be: 465 MW for a WWER-440 reactor with two 220 MWe turbines and 950 MW for a WWER-1000 reactor with a Skoda made 1000 MWe turbine using a three-stage scheme to heat up water from 60 grad C to 150 grad C. The use of satelite heating turbines connected to the steam collector is expected to improve the efficiency. District heating needs will de taken into account for siting of the new power plants

Present status of Tomari No.3 unit construction and efforts for preventing global warming

Hokkaido Electric Power Company, Inc. (HEPCO) supplies electricity to almost all area of Hokkaido. Its service area accounts for about one-fifth of Japan's area, on the other hand, the population of the service area only accounts for 4.4% of the nation. This means Hokkaido's nature is precious, and one of HEPCO's missions is to protect such environment, with providing stable electricity. Therefore, nuclear power, which does not emit greenhouse effect gas for generation, is becoming more important. HEPCO's operating nuclear power stations are Tomari No.1 unit and No.2 unit. Their generation capacity is 579 MW respectively. Now, No.3 unit is under construction. Its generation capacity is 912 MW and it will be operational in December 2009. In Hokkaido, about one fourth of electricity is now produced by nuclear power, however, after Tomari No.3 is completed, more than 40% of electricity will be produced by nuclear. So, Tomari No.3 unit will contribute stable supply of electricity in the first half of 21st century and prevent global warming in Hokkaido. This paper describes the present status of Tomari No.3 unit construction with major specifications and our efforts to prevent global warming. (author)

Industrial districts show characteristics that can be exploited by developing plant solutions studied for their special configuration and not simply extended from single unit models. In the paper a waste-to-energy plant for the chair industrial district in Friuli Venezia Giulia (North Eastern Italy) is described. It has been designed directly involving the University of Udine and can be considered an example of how technology innovation can be promoted by universities, especially in the case of small firms which have limited R and D resources. It is shown how industrial refuse becomes a chance of competitive advantage for the whole district due to its energy recovery in a plant unique for the type of waste processed. Input, combustion, energy recovery and cleaning sections are described in details, underlining innovative approaches and solutions [it

The Streltsovskoye uranium district

International Nuclear Information System (INIS)

Ischukova, L.P.

1997-01-01

This paper describes the geology of the Streltsovskoye uranium district located in south-eastern Zabaikalie region, Chita Province, Siberia, Russia. This district hosts Russia's only currently active uranium production centre. The uranium ore was discovered from 1963 to 1967 by drilling below fluorite veins which had minor associated uranium mineralization and radioactive anomalies. The uranium occurs as large scale vein stockwork deposits of hydrothermal origin within a volcano-tectonic caldera formed by continental volcanism of Late Mesozoic age. Rocks occurring in the caldera include basalt and trachydacite, overlain by rhyolite, and with associated interbedded sediments. The ore bodies occur in steeply dipping faults, with the greatest concentrations located where faults along the margins of the caldera intersect steeply dipping, cross cutting, northeasterly and northwesterly striking faults. The Streltsovskoye caldera extends over an area of 150 km 2 and is underlain by a large batholith. The 19 identified uranium deposits occurred in structural features that cut through the caldera sequence and extend into the basement rocks. The caldera has a maximum thickness of 1400 metres. Details of several deposits are given, including descriptions of mineralization and associated alteration. (author). 10 figs

Management of district hospitals--exploring success.

Couper, Ian D; Hugo, Jannie F M

2005-01-01

The aim of the study was to explore and document what assists a rural district hospital to function well. The lessons learned may be applicable to similar hospitals all over the world. A cross-sectional exploratory study was carried out using in-depth interviews with 21 managers of well-functioning district hospitals in two districts in South Africa. Thirteen themes were identified, integrated into three clusters, namely 'Teams working together for a purpose', 'Foundational framework and values' and 'Health Service and the community'. Teamwork and teams was a dominant theme. Teams working together are held together by the cement of good relationships and are enhanced by purposeful meetings. Unity is grown through solving difficult problems together and commitment to serving the community guides commitment towards each other, and towards patients and staff. Open communication and sharing lots of information between people and teams is the way in which these things happen. The structure and systems that have developed over years form the basis for teamwork. The different management structures and processes are developed with a view to supporting service and teamwork. A long history of committed people who hand over the baton when they leave creates a stable context. The health service and community theme cluster describes how integration in the community and community services is important for these managers. There is also a focus on involving community representatives in the hospital development and governance. Capacity building for staff is seen in the same spirit of serving people and thus serving staff, all aimed at reaching out to people in need in the community. The three clusters and thirteen themes and the relationships between them are described in detail through diagrams and narrative in the article. Much can be learned from the experience of these managers. The key issue is the development of a team in the hospital, a team with a unified vision of giving

Device for district heating with utilization of waste heat from power plants

International Nuclear Information System (INIS)

Korek, J.

1976-01-01

In order to utilize the waste heat developing in power plants - especially in nuclear power plants - the author suggests to lead the waste heat of the coolers for oil (which the bearings are lubricated with), hydrogen (which serves for the stator rotor-cooling), and the stator cooling water to the circulating district heating water and to arrange these heat exchangers one behind another or parallel to each other in the water circuit of the district heating system. The oil cooler of the engine transformer is also connected with the circulation of the district heating water. The runback water of the district heating network could thus be heated from approx. 40 0 C up to 65 0 C. (UA) [de

In August 1978, the United States Department of Energy and the Turlock Irrigation District entered into a cooperative agreement for a Joint District's Low-Head Hydropower Assessment Study. The purpose of the agreement was to carry out a study of the hydropower potential at sites within the borders of the Turlock, Merced, South San Joaquin, and Oakdale Irrigation Districts in California. The required data were gathered and analyzed. The results of this study indicate the total potential small hydropower capacity with the Joint Districts is 19,560 kW installed with an annual energy generation of 68,561,800 kWh. This is equivalent to oil-savings of 118,616 barrels per y.

A ward without walls? District nurses' perceptions of their workload management priorities and job satisfaction.

Stuart, Elaine Haycock; Jarvis, Alison; Daniel, Katie

2008-11-01

To explore district nurses' workload management, job satisfaction and the challenges they face. This paper reports qualitative findings from a qualitative and quantitative study to identify a district nursing perspective on use of time, challenges and work satisfaction. District nursing is under increasing pressure because of the increasing shift to care in the community, early hospital discharge and changes in demography with an ageing population and more people with chronic illnesses. Qualitative. The study took place in one Scottish Health Board and data were collected in February and March 2005. The qualitative approach involved a total of 31 district nurses and senior managers in focus group discussions or individual interviews. Three main themes were identified: (1) the priorities of district nurses and their views on work unrelated to 'hands on' clinical care, (2) aspects of district nursing considered stressful and (3) district nurses' job satisfaction. District nurses and managers agree that caring work with patients is the priority for the service and provides job satisfaction. Many nurses feel overwhelmed by their workload and have little control over the admission of patients to their caseload; they are mainly demand led and therefore reactive care providers. A culture of long hours has developed as district nurses struggle to meet the needs of patients. Feeling devalued lowers satisfaction and Agenda for Change is perceived as de-valuing the skills of community nurses. More clerical support is required so district nurses can deliver care to patients. District nurses can better represent their workload and how it is managed through expressing the nature of assessing risk and caring for patients as opposed to defining patients care needs by medical diagnoses. Extending the hours of the full district nursing service would benefit patients and staff.

Transition of neogene arc volcanism in central-western Hokkaido, viewed from K-Ar ages, style of volcanic activity, and bulk rock chemistry

Energy Technology Data Exchange (ETDEWEB)

Hirose, Wataru; Iwasaki, Miyuki; Nakagawa, Mitsuhiro [Hokkaido Univ., Sapporo (Japan)

2000-02-01

Spatial and temporal variations in late Cenozoic volcanism of southwestern Hokkaido at the northern end of NE-Japan arc have been clarified by 261 K-Ar and 76 FT ages including 49 newly determined K-Ar ages, volcanic stratigraphy, physical volcanology and whole-rock geochemistry. Arc volcanism characterized by rocks with low-Ti and Nb, and by across-arc increase in K{sub 2}O content in these rocks has continued at least since 12 Ma. Based on volcanic stratigraphy, physical volcanology and whole-rock geochemistry, volcanism after 12 Ma can be subdivided into 4 stages, 12-5, 5-1.7, and 1.7-0 Ma. The volcanism from 12 Ma to 5 Ma extended northward widely compared with distribution of Quaternary arc volcanism (1.7-0 Ma). This suggests that the arc trench junction between Kuril and NE-Japan arc's trenches was located about 100 km northward from the present position. Since around 5 Ma until 1.7 Ma, different type of volcanism under local extension field, characterized by a group of monogenetic volcanoes of alkali basalt and shield volcanoes of calc-alkaline andesite, had occurred at northern end of the volcanic region (Takikawa-Mashike region). During and after this volcanism, the northern edge of arc volcanism in the area has migrated southward. This suggests that the trench junction has migrated about 100 km southward since {approx}5 Ma. The quaternary arc volcanism (1.7-0 Ma) has been restricted at the southern part of the region. The volcanism since 12 Ma might be influenced by oblique subduction of Pacific plate beneath Kuril arc, resulting in the formation of local back arc basin at the junction and to southward migration of the trench junction.

Powell, Brian F.; Halvorson, William L.; Schmidt, Cecilia A.

2007-01-01

This report summarizes the results of the first comprehensive inventory of plants and vertebrates at the Tucson Mountain District (TMD) of Saguaro National Park, Arizona. From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also carried out extensive infrared-triggered camera work for medium and large mammals from 2002-2005 and results from that effort are reported here. Our spatial sampling design for all taxa employed a combination of random and nonrandom survey sites. Survey effort was greatest for medium and large mammals and herpetofauna. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an overview of previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. The survey effort for herpetofauna, birds, and medium and large mammals was the most comprehensive ever undertaken in the district. We recorded a total of 320 plant and vertebrate species, including 21 species not previously found in the district (Table 1). Based on a review of our inventory and past research at the district, there have been a total of 723 species of plants and vertebrates found there. We believe inventories for most taxonomic groups are nearly complete. Based on our surveys, we believe the native plant and vertebrate community compositions of the district are relatively intact, though some species loss has occurred and threats are increasing, particularly to herpetofauna and larger mammals. Of particular note is the relatively small number of non-native species and their low abundance in the district, which is in contrast to many nearby natural areas. Rapidly expanding development on the west, north, and east sides of

What variables should be considered in allocating Primary health care Pharmaceutical budgets to districts in Uganda?

Science.gov (United States)

Mujasi, Paschal N; Puig-Junoy, Jaume

2015-01-01

A key policy question for the government of Uganda is how to equitably allocate primary health care pharmaceutical budgets to districts. This paper seeks to identify variables influencing current primary health care pharmaceutical expenditure and their usefulness in allocating prospective pharmaceutical budgets to districts. This was a cross sectional, retrospective observational study using secondary administrative data. We collected data on the value of pharmaceuticals procured by primary health care facilities in each district from National Medical Stores for the financial year 2011/2012. The dependent variable was expressed as per capita district pharmaceutical expenditure. By reviewing literature we identified 26 potential explanatory variables. They include supply, need and demand, and health system organization variables that may influence the demand and supply of health services and the corresponding pharmaceutical expenditure. We collected secondary data for these variables for all the districts in Uganda (n = 112). We performed econometric analysis to estimate parameters of various regression models. There is a significant correlation between per capita district pharmaceutical expenditure and total district population, rural poverty, access to drinking water and outpatient department (OPD) per capita utilisation.(P Uganda (Adjusted R(2) = 0.528). All variables in the model are significant (p Uganda are: district outpatient department attendance per capita, total district population, total number of government health facilities in the district and the district human poverty index.

Urban district heating using nuclear heat - a survey

International Nuclear Information System (INIS)

Beresovski, T.; Oliker, I.

1979-01-01

The use of heat from nuclear power plants is of great interest in connection with projected future expansions of large urban district heating systems. Oil price escalation and air pollution from increased burning of fossil fuels are substantial incentivers for the adoption of nuclear heat and power plants. The cost of the hot water piping system from the nuclear plant to the city is a major factor in determining the feasibility of using nuclear heat. To achieve reasonable costs, the heat load should be at least 1500 MW(th), transport temperatures 125-200 0 C and distances preferably 50 km or less. Heat may be extracted from the turbines of conventional power reactors. Alternatively, some special-purpose smaller reactors are under development which are specially suited to production of heat with little or no power coproduct. Many countries are conducting studies of future expansions of district heating systems to use nuclear heat. Several countries are developing technology suitable for this application. Actual experience with the use of nuclear heat for district heating is currently being gained only in the USSR, however. While district heating appears to be a desirable technology at a time of increasing fossil-fuel costs, the use of nuclear heat will require siting of nuclear plants within transmission radius of cities. The institutional barries toward use of nuclear heating will have to be overcome before the energy conservation potential of this approach can be realized on a significant scale. (author)

Feasibility analysis of geothermal district heating for Lakeview, Oregon

Energy Technology Data Exchange (ETDEWEB)

1980-12-23

An analysis of the geothermal resource at Lakeview, Oregon, indicates that a substantial resource exists in the area capable of supporting extensive residential, commercial and industrial heat loads. Good resource productivity is expected with water temperatures of 200{degrees}F at depths of 600 to 3000 feet in the immediate vicinity of the town. Preliminary district heating system designs were developed for a Base Case serving 1170 homes, 119 commercial and municipal buildings, and a new alcohol fuel production facility; a second design was prepared for a downtown Mini-district case with 50 commercial users and the alcohol plant. Capital and operating costs were determined for both cases. Initial development of the Lakeview system has involved conducting user surveys, well tests, determinations of institutional requirements, system designs, and project feasibility analyses. A preferred approach for development will be to establish the downtown Mini-district and, as experience and acceptance are obtained, to expand the system to other areas of town. Projected energy costs for the Mini-district are $10.30 per million Btu while those for the larger Base Case design are $8.20 per million Btu. These costs are competitive with costs for existing sources of energy in the Lakeview area.

Despite recurring outbreaks of cholera in Ghana, very little has been reported on assessments of outbreak response activities undertaken in affected areas. This study assessed the response activities undertaken in two districts, Akatsi District in Volta Region and Komenda-Edina-Eguafo-Abirem (KEEA) Municipal in Central Region during the 2012 cholera epidemic in Ghana. We conducted a retrospective assessment of the events, strengths and weaknesses of the cholera outbreak response activities in the two districts making use of the WHO cholera evaluation tool. Information sources included surveillance and facility records, reports and interviews with relevant health personnel involved in the outbreak response from both district health directorates and health facilities. We collected data on age, sex, area of residence, date of reporting to health facility of cholera cases, district population data and information on the outbreak response activities and performed descriptive analyses of the outbreak data by person, time and place. The cholera outbreak in Akatsi was explosive with a high attack rate (AR) of 374/100,000 and case fatality rate (CFR) of 1.2 % while that in KEEA was on a relatively smaller scale AR of 23/100,000 but with a high case fatality rate of 18.8 %. For both districts, we identified multiple strengths in the response to the outbreak including timely notification of the district health officials which triggered prompt investigation of the suspected outbreak facilitating confirmation of cholera and initiation of public health response activities. Others were coordination of the activities by multi-sectoral committees, instituting water, sanitation and hygiene measures and appropriate case management at health facilities. We also found areas that needed improvement in both districts including incomplete surveillance data, sub-optimal community based surveillance considering the late reporting and the deaths in the community and the inadequate

Do district health systems perform differently because of their managers? Preliminary insights from Indonesia

Directory of Open Access Journals (Sweden)

Augustine Asante

2015-07-01

Full Text Available District health systems (DHS are central to the global efforts to improve health outcomes but many remain ineffective. In many lowresource settings, despite the generally weak DHS there is evidence that some districts consistently perform well against the odds, and this is often attributed to the calibre of managers leading such districts and their management and leadership (M&L skills. This paper examines the M&L practices of district health managers in high and low performing districts in Indonesia in an attempt to understand whether the differences in the performance of DHS can be explained, at least in part, by the differences in the performance of their health managers. We employed a mixed methods case study design focusing on two purposefully selected districts. Data were collected in 2011 using questionnaires and in-depth interviews. The preliminary results suggest that M&L practices of managers in the high and low performing districts are similar and provide little explanation for the differences in the performance of the two DHS. Contextual and health system factors offered a much better explanation for the variations in DHS performance.

Italian industrial districts: A model of success or a weak productive system?

Directory of Open Access Journals (Sweden)

Daniele Schilirò

2012-10-01

Full Text Available The present contribution focuses on two issues. The first one concerns the characteristics of industrial districts and the increasing weight of these districts in the Italian system of production. The second issue is about the competitiveness of the Italian industrial districts, if they represent a model of success or rather a weak system of production. Thus, the transformation of the industrial districts is examined and the strengths and weaknesses are highlighted. One argument that comes out of this investigation is that industrial districts are strongly influenced by institutions, territory, and also by the social and cultural environment. The second argument regards the competitiveness of this Italian industrial development model, based on SMEs, which is founded on the specialization of productions, on innovation and internationalization. The paper argues that this model, which represents the ``Made in Italy'', is still a strong and dynamic system which has shown good performances and it represents a paradigm of lasting competitiveness, even if it is restrained by many external chronic constraints.

Vani K. Borooah

2008-11-01

Full Text Available This paper asks: is it a fact that there is more violence in districts affected by Naxalite (Maoist activity compared to those which are free of Naxalite activity? And can the existence of Naxalite activity in some districts of India, but not in others, be explained by differences in economic and social conditions? This study identifies districts in India in which there was significant Naxalite activity and correlating the findings with district-level economic, social, and crime indicators. The econometric results show that, after controlling for other variables, Naxalite activity in a district had, if anything, a dampening effect on its level of violent crime and crimes against women. Furthermore, even after controlling for other variables, the probability of a district being Naxalite- affected rose with an increase in its poverty rate and fell with a rise in its literacy rate. So, one prong in an anti-Naxalite strategy would be to address the twin issues of poverty and illiteracy in India.

The Lisbon Valley district, however, is the only area with uranium deposits of substantial size. The stratigraphy of the Lisbon Valley district was investigated to determine the nature of the relationship between the mineralized areas and the lower Chinle sandstones. The geochemistry of the Lisbon Valley uranium deposits indicates a possible district-wide zoning. Interpretation of the elemental zoning associated with individual ore bodies suggests that humates overtaken by a geochemical oxidation-reduction interface may have led to formation of the uranium deposits.

Historic districts are a special type of cultural heritage, as living cultural heritage, the utilization and development of historical districts is an inevitable issue. How to accurately position the protection and utilization of districts and achieve its healthy and sustainable development is the key work in the protection of districts. In this paper, the Internet data including Tencent's location big data are employed to study some Chinese historic and cultural streets, establish protection and development index system for historic and cultural streets, carry out in-depth study of ten core indicators, and sum up the positioning and development direction for the protection and use of districts. Historic district, as a special type of cultural heritage, is the birthplace and supporting zone of urban context, and also the place for the daily life of the general public. It boasts profound historic and humanistic background and the characteristics of a living form. As the living cultural heritage, its use and development are necessary, and attention shall also be paid to static protection and dynamic comprehensive management. But judging from the current practice, protection and use of historic districts face a host of challenges. Some districts are devoid of popularity and vitality and become cold galleries. Some districts suffer excessive development for tourism and commercialism, and lose its "original" cultural characteristics. In addition, throngs of tourists exert a negative impact on the life of the local people and the protection of immovable cultural relics.

Swedish district heating—A system in stagnation: Current and future trends in the district heating sector

International Nuclear Information System (INIS)

Magnusson, Dick

2012-01-01

This paper argues that Sweden’s old and established district heating sector is heading into a stagnation phase. The aim is to analyse the factors influencing this development as well as the strategies used by involved parties to prevent stagnation. Using large technical system theory, I analyse internal and external factors potentially causing stagnation. The most obvious external factors are: an increase in the number of energy-efficient buildings, in response to stricter energy policies, which reduces the future potential for district heating in new and existing buildings; climate change; competition from other heating systems; and market saturation in the key sector, multi-dwelling buildings. The main internal factor is changed business strategies following electricity market deregulation, when energy companies were supposed to be run on businesslike terms. I also argue that stagnation can be defined as occurring when the key measure feature of a system, in this case, heat load is starting to stagnate or decline, even though the trend is positive in other areas. The strategies for avoiding stagnation are various forms of broadening scope, primarily by focusing more on electricity production by building combined heat and power plants, or using the alternative value of the technical system for new applications. - Highlights: ► The Swedish district heating sector is heading into a stage of stagnation. ► The main reasons are: climate change, competition and energy efficient buildings. ► Strategies to change trend: broadening of scope by focusing on electricity in CHP plants. ► Contribution to Large Technical Systems—theory and the later phases of system development.

Make the heat hotter. - marketing district heating to households in detached houses

Energy Technology Data Exchange (ETDEWEB)

Sernhed, Kerstin; Pyrko, Jurek

2008-09-15

For district heating (DH) companies, to expand in low heat density areas such as detached houses, it is essential to obtain a high rate of connections to the district-heating network in order to enhance the cost effectiveness. Marketing district heating to house owners is, however, a fairly different matter from selling it to customers in industrial, commercial, and multi-family buildings. Suitable market strategies need to be developed and the need for information about potential customers' preferences and attitudes are of great importance since the house-owners often constitute a heterogeneous group where different households have different requirements. This paper investigates a case of one Swedish district heating company's marketing activities and expansion strategies in a single family house area where the customers were offered conversion of their direct resistive electric heating (DEH) into district heating (DH). 88 out of 111 houses were converted in 2002. Four years later, interviews were carried out with 23 of the households in the area, both with those who had accept-ed the district heating offer and those who had not. The study shows that apart from the economic aspects, thermal comfort, aesthetics and practicalities also affected the buying decision. Since the different economic aspects of the offer were complex, it was very difficult for the households to make a strictly rational economical decision. Statistical analysis confirmed that variables such as age, type of household and energy use level could, to some extent, be related to the decision to convert from electric heating to district heating. Timing, low prices and the total solutions presented to the households were crucial factors in the success of the marketing strategy.

This paper reviews an experimental geochemical prospecting survey in the Blackbird cobalt-copper mining district. The district is in east-central Idaho, about 20 miles west-southwest of Salmon. The area is one of deeply weathered nearly flat-topped upland surfaces cut by steep-walled valleys which are tributary to the canyon of Panther Creek. Most of the area has a relatively heavy vegetative cover, and outcrops are scarce except on the sides of the steeper valleys* Because of the importance of the surficial deposits and soils and the physiographic history of the region on the interpretation of the geochemical data, a separate chapter on this subject by Gerald H. Richmond follows the following brief description of the geology of the district.

Calculating the marginal costs of a district-heating utility

International Nuclear Information System (INIS)

Sjoedin, Joergen; Henning, Dag

2004-01-01

District heating plays an important role in the Swedish heat-market. At the same time, the price of district heating varies considerably among different district-heating utilities. A case study is performed here in which a Swedish utility is analysed using three different methods for calculating the marginal costs of heat supply: a manual spreadsheet method, an optimising linear-programming model, and a least-cost dispatch simulation model. Calculated marginal-costs, obtained with the three methods, turn out to be similar. The calculated marginal-costs are also compared to the actual heat tariff in use by the utility. Using prices based on marginal costs should be able to bring about an efficient resource-allocation. It is found that the fixed rate the utility uses today should be replaced by a time-of-use rate, which would give a more accurate signal for customers to change their heat consumptions. (Author)

Simulation Models to Size and Retrofit District Heating Systems

Directory of Open Access Journals (Sweden)

Kevin Sartor

2017-12-01

Full Text Available District heating networks are considered as convenient systems to supply heat to consumers while reducing CO 2 emissions and increasing renewable energies use. However, to make them as profitable as possible, they have to be developed, operated and sized carefully. In order to cope with these objectives, simulation tools are required to analyze several configuration schemes and control methods. Indeed, the most common problems are heat losses, the electric pump consumption and the peak heat demand while ensuring the comfort of the users. In this contribution, a dynamic simulation model of all the components of the network is described. It is dedicated to assess some energetic, environmental and economic indicators. Finally, the methodology is used on an existing application test case namely the district heating network of the University of Liège to study the pump control and minimize the district heating network heat losses.

2015-01-01

District energy planning is an important methodology to assist in realizing a lower carbon target. However, district energy planning has not yet been incorporated into the statutory planning system in China, primarily because there are no clear standards and specifications for these plans. In this paper, we propose a general framework and low carbon estimation method for district energy planning, which is based on evaluating the low carbon energy planning practices of several new districts in China. In addition, several key points of concern in the planning process are extracted and discussed: overall infrastructure planning; co-operation between city planning and other special low carbon eco-planning; investment, financing and profitable operation; planning management mechanisms; and the management of the construction of the energy system to coincide with the project schedule. We carried out a case study of a low carbon energy plan for a new district of Beijing to evaluate our framework. Finally, we conclude that to realize the low carbon target, regional energy planning covering technologies, the market and management should be standardized as soon as possible. -- Highlights: •A general framework for district energy planning is proposed. •A case study of a low carbon energy plan for a new district is carried out. •District energy planning should be standardized as soon as possible. •The most suitable spatial scale for energy planning is at the municipal level

Uranium occurrences in the Gordonia and Kuruman districts

International Nuclear Information System (INIS)

Levin, M.

1978-11-01

This report highlights uranium occurrences discovered by the author in the Kuruman and Gordonia Districts. These discoveries are the result of follow-up work of the regional geological, hydrological and hydrochemical studies of the area, undertaken by the Geology Division of the Atomic Energy Board since 1974. A surficial uranium deposit was discovered on the farm Rus en Vrede in the Kuruman District, at the junction of a palaeo-river with the Kuruman River. Uranium occurs in carbonaceous diatomaceous earth, with surface samples assaying up to 308 ppm U 3 O 8 . As uranium is also present in calcrete 18 km south of this deposit, there is a distinct possibility that significant surficial deposits may occur under the Kalahari sand cover in this area. In the Gordonia District an interesting discovery was made on the farm Tsongnapan where four boreholes, drilled for water, intersected radioactive bands in the Dwyka Tillite Formation. These rocks, which outcrop in the northeast corner of the Tsongnapan, also proved to be radioactive. Some 35 km to the east of this occurrence, borehole logging indicated the existence of an anomalous zone near the base of the Dwyka. In some of these boreholes uranium anomalies were also found in the calcrete and gravel of the Kalahari Formation. It is evident, therefore, that the Gordonia District has the potential of becoming an economically important uranium province. A radiometric ground survey of one of the pans indicated that wind and water action is possibly responsible for the local dispersion and segregation of radioactive minerals [af
