    Compared with no music (NM), does listening to 'Achy breaky heart' (ABH) or 'Disco science' (DS) increase the proportion of prehospital professionals delivering chest compressions at 2010 guideline-compliant rates of 100-120 bpm and 50-60 mm depths? A randomised crossover trial recruiting at an Australian ambulance conference. Volunteers performed three 1-min sequences of continuous chest compressions on a manikin accompanied by NM, repeated choruses of ABH and DS, prerandomised for order. 37 of 74 participants were men; median age 37 years; 61% were paramedics, 20% students and 19% other health professionals. 54% had taken cardiopulmonary resuscitation training within 1 year. Differences in compression rate (mode, IQR) were significant for NM (105, 99-116) versus ABH (120, 107-120) and DS (104, 103-107) versus ABH (p0.5). Listening to DS significantly increased the proportion of prehospital professionals compressing at 2010 guideline-compliant rates. Regardless of intervention more than half gave compressions that were too shallow. Alternative audible feedback mechanisms may be more effective.

    An attempt was made to measure thickness of a layer of reservoir bottom sediments by utilizing the electromagnetic reflection method. Because water is a substance difficult for electromagnetic waves to permeate, considerations were given on to suppress attenuation to a minimum, and improve receiving sensitivity. The test used monocycle pulses with a central frequency of 200 MHz. In order to generate stabilized pulses with little unnecessary reflection, an antenna as large as it can be fitted into a rubber boat was employed. In order to acquire referential data, the test was carried out by using simultaneously a sound wave exploration device. The lake at which the test was carried out is a regulating reservoir with a size of about 250 m {times} 150 m, with its bottom made of concrete slab. This means that the lake consists of a three-layer structure comprising water, soil deposits, and concrete bottom from the water surface. According to an example of acquired electromagnetic exploration records, boundary reflection of water and sediments was observed clearly at water depths of 2 to 3 m as a shallow portion and 5 to 6 m as a deep portion. Reflection between the sediments and the bottom plate was also observed sufficiently distinctly. 3 refs., 8 figs.

    The methods for fixation of carbon dioxide in the atmosphere in order to control the greenhouse effect, are groped. Carbon is fixed through two ways such as the production of organic compounds by photosynthesis and formation of calcium carbonate by calcification. Among them, the photosynthesis fixes carbon dioxide in the air, and calcification, on thinking of only chemical equilibrium in the sea water, is a process to exhaust carbon dioxide from ocean to the atmosphere. It is, therefore, uneven in opinions of researchers if the coral reef is an absorbing source or an exhausting one of carbon dioxide. A conventional discussion on this theme, did not carry out based on the actual search or measurement, but preceded on modelling. In order, therefore, to introduce a scientific decision on a play of the coral reef for the global carbon circulation, it seems to take more time. In this paper, an opinion that the coral reef is an absorbing source of carbon dioxide in the air according to some measuring results of carbon dioxide fixation velocity and organic compounds volume in sediments in the coral reefs, are described. 11 refs., 4 figs.

    In order for a coral reef to be a CO2 absorbing source, a condition would have to be satisfied that, with respect to production of organic carbon through photosynthesis, a total production by coral reef organism association is large, and the ratio of the total production to a total consumption is more than one. A requirement that the ratio of inorganic carbon production through calcification be 1.5 or more must also be met. Measurements have been carried out at coral fields off the Ishigaki Island by the Geological Research Center. The measurement results revealed that production is high for both of organic carbon and inorganic carbon, surplus organic carbon is produced, and CO2 is absorbed into the coral reefs. It was also found by measuring the stable isotope ratio of nitrogen in coral reef organisms that nitrogen required for the production in the coral reefs is supplied from the atmosphere through nitrogen fixation. The paper adds a description that CaCO3 deposition in the coral reefs has peaked in 5000 years to 6000 years ago, and it is in a ceiling-hit condition now. 25 refs., 3 figs.

    Bulks of photosynthetic product to reduce the carbon dioxide by the light energy are forests, represented by the tropical rain forests, on the land, and marine algae and coral reefs in the ocean. For the purpose of effectively utilizing the fixation power of carbon dioxide through the photosynthesis by higher plants and algae, it is necessary to make many further researches, starting with a conditional selection of species, excellent in both absorption and fixation of carbon dioxide. The Japan Technology Transfer Association has recently issued a design to build a large scale closed type farm in the vicinity of factory, exhausting the carbon dioxide, and supply it to structure a system of producing vegetable and other food. What largely contributes to the calcification in the ocean is the coral reefs, where coral is symbiotic with brown algae., called dinoflagellatae. Those algae are judged to accelerate the formation of calcium carbonate by the photosynthesis. To estimate the absorption power of oceanic carbon dioxide, it is important to quantitatively know the calcification by the coral. 4 figs., 1 tab.

    This paper explains CO2 fixing mechanisms in coral reefs and technologies to construct coral reef eco-factories. A coral reef fists CO2 through two routes of photosynthesis and calcification, with both processes proceeding conjugately. Calcification is driven by the photosynthesis that proceeds at a rate more than ten times faster than the calcification. The Geological Survey of Japan is working on elucidating CO2 fixing mechanisms in coral reefs and studying coral reef eco-factory structuring technologies to utilize the capability of the mechanisms at a possible maximum extent. This study is directed to optimizing site conditions for coral reefs, optimal arrangements and environmental conditions for clusters, and production process determining factors. The structuring technologies may include controlling water temperatures, water flows, nutritious salts, and suspended substances that match optimal CO2 fixing conditions in coral reefs; seeding technologies for coral reef organisms; aquaculture techniques utilizing fixed CO2; combination with cultivating techniques; and combination with new energy technologies including sea water temperature difference power generation to control water flows and maintain facilities. 4 refs., 5 figs.

    This paper describes the following matters on CO{sub 2} fixation using living organisms, and marine organisms in particular. For CO{sub 2} fixation using land organisms, promotion is urged on desert greening and forestation with fast growing trees. The CO{sub 2} transfer into deep sea beds with sea water circulation is a slow process, requiring several hundred to one thousand years before the CO{sub 2} increased in the atmosphere is absorbed into deep sea water. Precipitation of organics produced by photosynthesis of vegetable planktons on the ground surface also contributes to the CO{sub 2} transfer into deeper ground. If the CO{sub 2} fixing speed in coral reefs in Okinawa and Hawaii is applied to the coral reefs all over the world, it will mean a CO{sub 2} fixation being carried out corresponding to an annual increase in the forest area of 10,000 to 200,000 km{sup 2}. The paper touches on technological development to fix CO{sub 2} by propagating vegetable planktons on ocean surface with supply of nutritious salt, or to discard liquefied CO{sub 2} from thermal power plants into deep sea beds. 32 refs., 7 figs., 1 tab.

    Notice has been given on a calcareous alga among micro marine algae that play an important role in carbon circulation, and the representative alga, Cricosphaera carterae was cultured to discuss growth and carbon fixation rate experimentally. It was found that nutrient salt is taken in more actively in the bright period during which no fission occurs, and less actively during the growth stage in the dark period. Dependence of nitrate concentration on specific growth rate was measured with semi-continuous culture and two formulas were formulated. The specific growth rate was 0.53/d at an average nitrogen concentration on the ocean surface of 15 mg/m[sup 3]. The maximum specific growth rate was 0.9/d, and the fixing ratio of inorganic carbon to organic carbon was roughly 0.1. Further, the alga was cultured with CO2 concentration doubled (to 715 ppm), where no large difference was discovered in the growth and the inorganic carbon fixation. From these findings, the carbon fixation amount due to algae on the entire earth was calculated to roughly 4 billion tons per year. 23 refs., 10 figs., 4 tabs.

    Study was made for grasping the basic data of CO2 fixation technology by seaweed. The photosynthesis under the sea, which is different from that on the land, is judged to be made by taking in HCO3[sup -] and converting it into CO2 inside the plant. Porphyra yezoensis which is seaweed is cultivated as comestible. With a rise in CO2 content, the growth in length of leaves was observed to be accelerated through ventilating Porphyra yezoensis with the three test types of air which respectively contained 350ppm (atmospheric CO2 content), 1000ppm and 1600ppm CO2. As a result of measuring the photosynthesis speed by the generated quantity of O2, it was heightened with a rise in dissolved inorganic carbonic acid content of the sea water. Measurement was also made of daily fluctuation in calcification speed by Corallina officinalis capable of calcification by ventilating it with 350ppm and 1600ppm CO2. In case of 1600ppm, the sedimentation of CaCO3 was prevented. In case of 350ppm, the sedimentation was quantitatively larger during the bright period than that during the dark period. The growth of Gracilaria gigas which is an agar material was compared by changing the above CO2 levels. In case of 1600ppm, the weight grew to 2.3 times in 20 days. 16 figs., 2 tabs.

    A method is developed of applying near infrared rays to the drying of paint coatings on resin-made automobile parts, and its environment improving effects are described. Using the conventional hot-air dryer for the drying of such coatings, the portion near the top surface is hardened prior to the other portions because the heat is absorbed near the top surface. Using an infrared drying system, however, defects in the product surface attributable to the lack of uniformity in the hardening of paint or to the splashing of solvent are remedied because deeper portions are hardened first. Experiment and study are conducted for the purpose of applying a near infrared drying method to an ABS (acrylonitrile butadiene styrene) coating. It is found that the near infrared drying method takes only seven minutes to dry a paint coating for which a hot-air furnace will take 20 minutes, thus shortening the drying time a great deal. Defects of gas hole of coatings are generally dealt with by changing the setting time and drying conditions for example by increasing the amount of the diluting thinner. When an near infrared drying method is used, the amount of the diluting thinner is reduced approximately 50% from the amount required using the hot-air drying method in case of the thickness of 60{mu}m. 2 refs., 9 figs., 2 tabs.

    To cope with the global warming caused by CO2, an investigation was conducted into biological fixation. It is necessary to make a many-sided and comprehensive study on the mechanism of CO2 fixation, the scale (area and carbon holding density), the rate and the environmental impact of the introduction of the technology and the technical problems, and to make a quantitative evaluation of each of the methods in order to make them practical proposals. The global ecosystem is classified into the land biota and ocean biota, and each typical ecosystem was surveyed in terms of the surface area, the carbon holding amount (presently existing amount), the net primary production amount, the required nutrient salt amount, the transpiration rate, etc. Next, a discussion was made on the increasing effect of the carbon fixation amount by changing the present ecosystem from the aspect of scale and rate. At the same time, a study was carried out of energy efficiency, economical efficiency and problems. Last, elementary technology was taken up which seems to be important for implementing measures for the biological carbon fixation. As to the ocean, it is necessary to obtain information, which is not sufficient to utilize marine biota for CO2 fixation, especially on the mechanism of depth-direction transfer of organism and its quantitative grasp. As to the land, one of the measures is conversion of the ecosystem where the amount of carbon fixed is small to the ecosystem where the amount is large. 249 refs., 58 figs., 51 tabs.

    Various kinds of biological fixation processes of CO2 were evaluated from the various viewpoints. Afforestation of tropical and temperate areas, greening of desert, biomass energy production in these areas by energy plantation, coastal mangrove plantation, fertilization with nitrogen and phosphate to outer ocean and coastal, upwelling zone fertilization with iron, and coral reef expansion combined with OTEC (ocean thermal energy conversion) were comparatively investigated as the selected measures. As a result, the cost of CO2 fixation by cultivation of sea weed and plankton was much higher than that of afforestation. The iron fertilization method which was considered to be one of the high CO2 reduction potentials might be economical. However, its effect could not be quantitatively evaluated. The afforestation of tropical and temperate areas seemed to be most feasible in a short term from the viewpoints of economy and environment. It was suggested that the establishment of a systematic water management technology could make greening and afforestation of desert. 76 refs., 27 figs., 28 tabs.

    In order to achieve collection and effective utilization of CO2 as the representative greenhouse effect gas, through use of microorganism functions, a survey was performed on problems when the CO2 fixation system is applied to factories, based on the results of surveys in fiscals 1997 and 1998 and the supplementary surveys therein. Discussions were given on feasibility and effect of introducing the in situ CO2 fixation systems. With regard to the current status and problems in technologies to fix and utilize effectively CO2 by use of photosynthetic bacteria and micro algae by means of solar beam, the paper summarizes the 'searches and breeding of bacteria and algae' and the 'research and development of a high-density and large-quantity cultivation system such as for CO2 fixation and useful substance production'. The paper also describes problems in the CO2 fixation technologies utilizing bacteria and algae. With regard to the CO2 fixation technologies utilizing bacteria and algae, the paper summarized the contents of the survey on CO2 fixation by using photosynthetic bacteria, clostridium bacteria, and coryne bacteria. Surveys were performed inside and outside the country on kinds and existence quantities of unutilized organic wastes in which microorganisms that fix CO2 can be utilized. The CO2 fixation systems can be considered of their possibilities of being introduced into foodstuff factories where organic waste water with high concentration can be obtained. (NEDO)

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    A study was conducted on how to fix CO2 in the ocean using coral reefs. Coral reefs have extremely high primary productivity ( production quantity of organic matters by photosynthesis) and are expected to be resources to fix CO2 when the quantity of photosynthesis exceeds the quantity of CO2 emitted in association with formation of calcium carbonate skeleton. If organic substances produced in coral reefs are well carried into the open sea, those are settled down on deep beds, which enables the storage into the ocean. At the coral reef floating in the ocean, it is not very deep inside and the seawater stays there, but it has a steep depth outside. By the numerical calculation, an examination was made on how the waterflow changes when making the flow path of seawater between the inland sea and open sea. From the actual calculation of an atoll, it was found that seawater comes in and out from the open sea to the inland sea near the opening of the atoll in accordance with the high tide and ebb tide, but the water stays at the deep bottom of the atoll. When installing a channel with a 10m depth at the portion where the water flows softly, the seawater was actively exchanged. 6 refs., 4 figs.

    For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

    The trend of technology is surveyed from a standpoint that, in the process of CO2 fixation using microbes for the production of useful substances, it is essential, in view of income/outgo balance and economy, to utilize their catalytic function. The survey centers about the feasibility of the utilization of organic wastes, cellulose wastes in particular, as an energy source. Special attention is paid to the energy of artificial light and laser beams. From a point of view that it is important to suppress cell multiplication and to effectively utilize only catalytic activity for the production of useful substances, the cell division mechanism of the Corynebacterium is analyzed, and the findings are compiled to facilitate the study as to whether the division may be controlled. A report is also prepared on the metabolic mechanism of a photosynthesizing bacterium that is judged to be the most promising species. Reference is made to aerobic and anaerobic bacteria. Shown are the organic compounds that are formed by CO2 gas fixation thanks to microbial or enzymatic reactions. To emphasize their importance as an energy source and to explain the conversion of biomass into useful substances, the technology and economy of conversion into fuel compounds are surveyed. The production of ethanol out of organic wastes is evaluated in the way of LCA (life cycle assessment). (NEDO)

    This survey is aimed to investigate various measures to be taken for biological CO2 fixation, to synthetically study feasibilities of the measures from various aspects of CO2 fixation mechanism, scale, speed, and environmental effects and technical problems in case of introducing those, and to assess the measures quantitatively. In this fiscal year, a study was proceeded with of possibilities of carbon fixation by afforestation and that by fertilization into ocean. The paper defined significance of afforestation in arid land, and especially advantages in conducting researches in West Australia. Relationships were examined among afforestation, precipitation and topography. The result of the survey was described of water- and salt-transfer simulation methods. Studies of arid land were made in terms of photosynthetic speed, transpiration speed, soil characteristics, measuring methods for precipitation and vaporization amount, and the examples. Seven places of Leonora where water source and water quality were examined were selected, and the measuring results were described. The paper summed up the state of utilization of biomass energy obtained from forest and commented on a scenario on tree-planting. Finally, a possibility was stated of the carbon fixation by fermentation into ocean. 178 refs., 121 figs., 53 tabs.

    Before submitting propositions on important technological tasks to be generated in the automobile production line upon application of IT (information technology), a questionnairing is implemented to know the actualities of the line for the purpose of planning a proper merger of IT and the manufacturing technology development capability of the IT accepting site. The questionnaire, aiming at the embodiment of the goals of the projects 'IT related technical tasks relative to its helping human creation of new technologies and enhancement of human ability to make improvement' and 'Technical tasks of developing technical skills into technologies,' asks engineers about the actualities of knowhow at automobile production lines and its development into technologies, about how they take care of what they learned from their predecessors, and about their expectations from and views and opinions toward IT introduction and utilization. It is important to efficiently utilize IT as a means to solve problems involving the knowhow related training on the production line and the handing down of the acquired knowhow to the juniors. Since individual workers' knowhow assumes a certain role at each stage of the automobile production line and since it is necessary to extract the maximum from each worker and to utilize the fruit for improvement on productivity and work efficiency, it is indispensable to efficiently merge the knowhow with IT.

    Among many environmental problems now the world is facing with, the increase of CO2 concentration in the atmosphere is considered to give rise to many phenomena causing such serious effects as abnormal weather, water shortage, food shortage, etc., hence predictions by climate models are being tried at many places in the world, and any of them predicts a temperature rise due to the increase of gases such as CO2 causing the green house effect. In this article, an experiment has been carried out which cultures chlorella capable of fixing CO2 by using the exhaust gas actually emit from the sludge incinerator inside the South Sewage Purification Center of Kofu City, Yamanashi Prefecture. As a result, it has been theoretically concluded that a CO2 fixation system can be constructed inside the above center, but it is necessary to consider the balance between working electric energy during the system operation and the amount of CO2 fixation by the above system. In case when the electric power from a commercial power plant is used for the operation of the system, such usage becomes meaningless unless the system fixes CO2 more than the CO2 discharge by this power generation. 11 refs., 5 figs., 4 tabs.

    In order to achieve collection and effective utilization of CO2 as the representative greenhouse effect gas, through use of microorganism functions, a survey was performed on problems when the CO2 fixation system is applied to factories, based on the results of surveys in fiscals 1997 and 1998 and the supplementary surveys therein. Discussions were given on feasibility and effect of introducing the in situ CO2 fixation systems. With regard to the current status and problems in technologies to fix and utilize effectively CO2 by use of photosynthetic bacteria and micro algae by means of solar beam, the paper summarizes the 'searches and breeding of bacteria and algae' and the 'research and development of a high-density and large-quantity cultivation system such as for CO2 fixation and useful substance production'. The paper also describes problems in the CO2 fixation technologies utilizing bacteria and algae. With regard to the CO2 fixation technologies utilizing bacteria and algae, the paper summarized the contents of the survey on CO2 fixation by using photosynthetic bacteria, clostridium bacteria, and coryne bacteria. Surveys were performed inside and outside the country on kinds and existence quantities of unutilized organic wastes in which microorganisms that fix CO2 can be utilized. The CO2 fixation systems can be considered of their possibilities of being introduced into foodstuff factories where organic waste water with high concentration can be obtained. (NEDO)

    The present report introduces the basic research on the production of PHB (one of the biodegradation plastics) by utilizing the photosynthesized microorganisms. The indigo algae are conveniently used for the genetic operation, because they are genetically inferior and have plasmid (extranuclear ringed DNA). Therefore, a certain type of oceanic indigo algae was used for the present research. As a vector to introduce the PHB-producing gene into the indigo alga cell, hybrid plasmid was prepared by combining the indigo alga plasmid pAQ1 with colon bacillus plasmid vectors pUC19. The thus prepared vectors had an introduction efficiency into about 1000 cells per one vector. A RuBisCO gene of indigo alga cell was selected as a promoter to heighten the activity of PHB-producing gene in that cell. The gene is being further studied in promotion efficiency by combining it with the above vector and PHB-producing gene. 4 figs.

    An investigational study was conducted of a project for energy conservation and greenhouse effect gas reduction by introducing the steam injection gas turbine generator to production facilities of the Siam Cement Industry Corporation (SCI) in Thailand. In the project, studies were made on the following: no purchases of electric power by introduction of the steam injection gas turbine generator; additional heating by gas turbine exhaust gas by introduction of the kiln combustion air heater; remodeling of the preheater of raw materials, and the partial calcination before kiln sintering by introduction of the calcination furnace. As a result of the study, the energy conservation amount was 1,200 toe/y, and the greenhouse effect gas reduction amount was approximately 8,000 t-CO2/y, which led to the reserve power for increased production of clinker by about 18%. The size of investment was 314.5 million Baht in total. As to the evaluation of economical efficiency of the investment, the actual period of ROI was a little less than 5 years, and the internal earning rate was 17.7%, which substantially met with SCI's standards for equipment investment. However, there are problems on the gas supply infrastructure, recovery of the white cement demand, etc. (NEDO)

    This paper describes photosynthetic function of plants, and CO {sub 2} fixing function of marine organisms. Among the photosythetic reaction systems, the C {sub 3} type reaction carries out CO {sub 2} fixation using the Calvin cycle, and takes out the carbon dioxide out of the system through enzymatic reactions of 3-phosphoglycerate {yields} fructose-6-phosphate. The C {sub 4} type reaction has a special cycle to supply CO {sub 2} to the Calvin cycle, i. e. C {sub 4} dicarboxylic acid cycle. The CAM type reaction enables the photosynthetic type to be converted according to variations in the growing environment. The majority of the surace agricultural crops are from C {sub 3} plants, of which yield may be increased when grown in a high CO {sub 2} atmosphere. On the one hand, gene engineering may make possible breeding of plants having high CO {sub 2} fixing capability. In the area of marine organisms, lime algae growing in clusters around coral reefs form and deposit CaCO {sub 3}. Reef creating corals have symbiotically in their stomach layer brown algae having photosynthetic function to build CaCO {sub 3} skeleton. The corals calcify algae quickly and in a large quantity, hence play an important role in fixing underwater CO {sub 2}. 2 tabs.

    Full Text Available Repeated concussion is becoming increasingly recognized as a serious public health concern around the world. Moreover, there is a greater awareness amongst health professionals of the potential for repeated pediatric concussions to detrimentally alter the structure and function of the developing brain. To better study this issue, we developed an awake closed head injury (ACHI model that enabled repeated concussions to be performed reliably and reproducibly in juvenile rats. A neurological assessment protocol (NAP score was generated immediately after each ACHI to help quantify the cumulative effects of repeated injury on level of consciousness, and basic motor and reflexive capacity. Here we show that we can produce a repeated ACHI (4 impacts in two days in both male and female juvenile rats without significant mortality or pain. We show that both single and repeated injuries produce acute neurological deficits resembling clinical concussion symptoms that can be quantified using the NAP score. Behavioural analyses indicate repeated ACHI acutely impaired spatial memory in the Barnes maze, and an interesting sex effect was revealed as memory impairment correlated moderately with poorer NAP score performance in a subset of females. These cognitive impairments occurred in the absence of motor impairments on the Rotarod, or emotional changes in the open field and elevated plus mazes. Cresyl violet histology and structural magnetic resonance imaging (MRI indicated that repeated ACHI did not produce significant structural damage. MRI also confirmed there was no volumetric loss in the cortex, hippocampus, or corpus callosum of animals at 1 or 7 days post-ACHI. Together these data indicate that the ACHI model can provide a reliable, high throughput means to study the effects of concussions in juvenile rats.

    With objectives to elucidate whether CO2 fixation quantity can be increased by utilizing the features of ecological systems, and know what degree the increasing possibility is at, surveys were performed on (1) the 'possibility of carbon fixation by means of afforestation in arid regions', and (2) the possibility of carbon fixation by applying fertilizers into oceans'. With respect to the (1) afforestation in arid regions, surveys were performed mainly in the West Australian Province to elucidate the current status of carbon fixation quantity, its possibility for increase, water balance, importance of soil structures, and effects of salts (including nutritious salt) on vegetation. Regarding the (2) fertilizer application into oceans, elucidation was made on circulation of organic matters in oceans, effects of applying ferrous fertilizers on the carbon fixation, and the importance of supplying inorganic nitrogen during the fertilizer application. The material cost for scattering irons at this time was calculated as two dollars per ton of carbon fixation quantity. Surveys were also carried out on processes of decomposition of particulate organic matters, and the change in the C/N ratio during the processes. Proposals were presented on preparing the platform that can calculate the carbon fixation quantity when water, soil, nutritious salt, afforestation, and climate are changed, and on preparing the scenario that can increase the carbon fixation quantity in the order of 1Gt-C/y.

    The operation continues of the experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si, and efforts are under way to carry out improvements, to verify such improvements for the results, and to develop operation control technologies. During the operation, improvements are made with respect to the length of stable operation period, granule quality, and device operation, and the results are verified. An automated control test system is verified, and a reactor tube newly developed by Shin-Etsu Chemical Company is subjected to a durability verification test. On the other hand, development is started of SiC-CVD (chemical vapor deposition) technology for materials for large reactor tubes, studies are started on a basic experimental device, basic studies are conducted for designing a large reactor, and investigations are conducted of a large plant conceptual design, an automated control system for reactors, and so forth. The results achieved are all found to be satisfactory. Above all, the granule quality is improved to be quite high in purity, and a cast cell made from improved granules exhibits a photoelectric conversion efficiency to exceed 13%. It is also found that the newly developed reactor tube is stronger than conventional reactor tubes and will be advantageous over others in the future enlargement of devices. (NEDO)

    The aim is to develop a fluidized bed reactor high in productivity and low in power consumption for the realization of mass production of low cost polycrystalline silicon usable for solar cell construction. An experimental device capable of producing 10 tons/year of SOG (spun on glass)-Si is built and operated. The fluidized bed reactor treating trichlorosilane as the material and the product quality achieve the initially set goals, and the essence is seized of operation management technology. In fiscal 1986, for development of the technology into a practical application technology, designs are prepared for a larger reactor unit and a large plant of the commercial scale. From the viewpoints of production efficiency and cost, the enlargement of a reactor unit is an inevitable task to discharge before practical application. There are two challenges to meet. One is the development of technologies for manufacturing large reactor tubes strong enough to withstand practical service and the other the development of a reactor structure fit for dimensional enlargement. It is then found that the concept of an economically optimum design relative to device series or device block formation is variable in the case of large plants, dependent on the scale of production, and that therefore it is necessary to arrange problems in a proper order to facilitate further deliberation.

    A prototype force control piston insertion device which does not need jigs is built for use on the assembly line. An extensive reduction in investment for automated facilities is expected to realize because jigs conventionally required for each size are dispensed with. For expanding the scope of force control application, the device is verified for serviceability by use of a 5-axis robot and a visual servo control technique. A combination of vibration control and tracking control is applied to an integrated simulation/experiment environment. For the processing of inner force sensor data, a pseudo contact point monitoring technique is used. A wire type tactile sensor is proposed, which has a flexible-structure moment detector in which a flexible beam like a piano wire is the probe. For the inspection of ICs (integrated circuits), a passive compliance unit and a force control based flexible inserter are fabricated, to be used for a reduction in the number of no-good contacts. Technologies of shock absorption aided by robot terminal device tactile sense and of virtual damper control for shortening the setting time are verified for their validity by use of the IC inspecting inserter.

    Research and development has been performed with an objective to reduce discharge of dioxins in aluminum product manufacturing processes. With regard to the quantity of chlorine used in aluminum molten metal refining process, the refining tests using 100% chlorine gas and the mixed gas (nitrogen gas mixed at 80%) revealed that either gas has approximately the same degassing performance, and the use of the mixed gas can reduce the amount of chlorine used. Dioxin concentrations in the gas discharged from the refining process were measured under the refining condition using less amount of chlorine. As a result, it was verified that, in the case of using 20% chlorine gas plus 80% nitrogen gas, the concentrations of dioxins decrease to about l/6, or 0.6 ng-TEQ/N{sup 3}. The studies on suppressing the discharge of dioxins from the facility to wash chlorine treatment exhaust gas discovered that dioxin concentration in the scrubber circulating solution can be suppressed to 1/10 or less by means of gravity precipitation and separation of the suspended liquid. It was also made clear that pH should preferably be controlled to 10.5 to separate suspended substances from the precipitated solution. (NEDO)

    Research and development has been performed on a scrap melting process to make dioxins emission concentration to 0.2 ng-TEQ/Nm{sup 3} or less in steel making electric furnaces. The testing facility is of semi-sealed structure, consisting of an arc dissolution furnace, an exhaust gas combustion section, an auxiliary combustion chamber, and a quenching chamber. In the arc dissolution chamber, oxygen and coke are blown in at the same time as turning the arc power supply on, and then secondary combustion air was blown in to burn carbon monoxide gas generated from steel melting. The temperature was raised to about 850 degrees C at which dioxins are decomposed in the auxiliary combustion chamber, and then quenched to 200 degrees C or lower in the quenching chamber to prevent recombination of dioxins. As a result of the test, the exhaust gas temperature after the combustion was estimated to have reached about 900 degrees C at which dioxins are decomposed. In addition, because it was possible to control the exhaust gas temperature at the outlet of the auxiliary combustion chamber to about 850 degrees C and the exhaust gas temperature at the outlet of the quenching chamber to 200 degrees C or lower, the dioxins concentration at the outlet of the quenching chamber was reduced successfully to the targeted value or lower.

With regard to oceans, problems and effects are described on fertilization by sprinkling wide area of ocean with nutrient salts for CO2 fixation by means of the ecosystem. Nutrient salt addition is effective in increasing production of organic matters, but what is important is the understanding about food network balance and elementary process of the ecosystem. Composition of organic matters migrating into greater depths is one of the important parameters.

    Studies are conducted to enlarge the diameter of polycrystalline Si castings and to develop a low-loss slicing method using silicon nitride powder as mold releasing agent. The apparatus for Czochralski's pulling process is improved and tested using SEG (selective epitaxial growth) Si, and now the casting of a 150mm-diameter ingot is feasible. Also, test production of a 94mm-square wafer as specified by NEDO (New Energy and Industrial Technology Development Organization) is successfully carried out. Difficulties in separating the mold releasing agent from the crucible are solved by changing the Si{sub 3}N{sub 4} power solution from PVA (polyvinyl alcohol) to ethyl silicate. The design, manufacture, and installation of the important parts of the system for the mass production of castings are now complete. The crucible is designed to be movable relative to the heater section, and the molten Si is allowed to cool and solidify from the bottom upward. In relation with the development of low-cost wafer manufacturing technologies, low-loss slicing methods are studied. It is concluded that under the current circumstances a multi-blade saw is more promising than the multi-wire saw in view of the damaged slice rate, processing speed, operating cost, and maintainability.

The installation of a 10 tons/year class model plant for SOG-Si production is completed in July 1982. Flaws are removed after a test run, and four reactions are accomplished without damage on the reactor tube in the period from February-end to March-beginning marking 550 hours of operation in total. Thanks to the four operations, 1,086kg of granules are experimentally produced and an electric power consumption rate of 30.6KWH/kg Si is achieved, control of the flowing particle amount by reactor differential pressure is accomplished and the same of the yield by recovered silane liquid composition analysis, and essence is seized of operation control technologies. In an experimental apparatus for seed production, Si is crushed by a roll crusher and then subjected to separation by a quartz-made air elutriator.

A study is made of ten operations (total reaction time of 2,264 hours), and it turns out that the electric power consumption efficiency is near the initially planned value. The yield of Si is, however, but 16.5% which is lower than the initially planned value of 20%. The value is elevated to 18% by raising the reactor temperature. To prevent overcleaning, a reactor with its internal walls experimentally coated with SiC is tested. The problems with devices other than the reactor tube are extraction rendered difficult by anomalously grown granules and processing devices choked by Si powder contained in waste gas after reaction. The first problem is settled by modifying the extraction tube but the other still needs a remedy. The produced granules are found to be high in quality. The seed producing roll crusher is operated for a total of 92 hours yielding 857kg in total. (NEDO)

    To increase international competitiveness, the construction of highly productive systems capable of autonomously accommodating changes in manufacturing processes is indispensable. Robot technologies for flexible, robotized manufacturing lines will be established, and robotization will be promoted in industries related with transportation equipment and semiconductor in and near Kumamoto City. Optimization is to be achieved in such processes as IC chip insertion so that piston insertion into a cylinder with but an extremely little gap between them will be performed without scratches on the cylinder walls and that no plastic deformation will occur in the initial lack of positional correspondence. The technological tasks to be carried out include position detection based on visual information and skill making up, micro-force sensor of great precision and flexible force control, coordinated control of different types of robots, flexible handling mechanism, and integration of different techniques based on an information management system. The control of force now being exercised by humans will be reviewed from a new point of view and harmonization will be established between the human endeavor and sensing devices. Conceptual designs will be completed by the fiscal year end, with efforts concentrated on two prototypes, one for assembly lines and the other for IC inspection. (NEDO)

    The chlorosilane hydrogen-reduction technology development period may be divided into the first phase (fiscal 1980-1985) and the second phase (fiscal 1986-1988). During the former phase, efforts were exerted to develop a small experimental device (10 tons/year class) and technologies to operate the same. Important challenges were to cause reaction to occur only on the seed grains in the reactor and to create a proper material for the reactor tube. In the latter phase, element technologies were developed, indispensable for the development of a practical reactor. Endeavors exerted to solve these challenges were the development of a high-strength large-diameter reactor tube, the development of an SiC-CVD (chemical vapor deposition) coating technology, and the development of a technology to join parts to the ceramic-made reactor tube. After eight years' striving, a fluidized bed reactor has been successfully constructed, capable of continuously reducing trichlorosilane by hydrogen. The success promises stable production and supply of polycrystalline silicon. The SOG (spun on glass)-Si produced by the reactor is pure enough to serve the purpose of photovoltaics, and its unit cost has been lowered as initially intended. (NEDO)

    In fiscal 1984, studies are conducted for long-time stabilized operation of the device (extension of reactor tube service life, elimination of flaws in the granule extraction process, control of deposited silicon), improved granule quality (measures to deal with Cu pollution), cost reduction (improvement on yield of silicon after reaction, reduction in electric power consumption rate), and so forth. The results are found to be satisfactory in outline. The problem of strengthening the reactor tube material itself remains to be solved, however, with many knotty issues to settle before practical application. In the effort to deliberate these difficulties, as many as 4,377 hours (reaction hours) in total are spent in fiscal 1984. During the operation, 8.3 tons of granules are produced of which approximately 7 tons are fed to the next stage of processing. The quality of granules produced in this way is stable thanks to efforts to prevent pollution and to prolong continuous reaction time, and is found to satisfy NEDO (New Energy and Industrial Technology Development Organization) specifications. Furthermore, the cast cell and the ribbon cell using thus-produced granules achieve photoelectric conversion rates of 10% and 9%, respectively, thereby meeting the target goal of 9%. (NEDO)

    Since its construction in 1982, the experimental device capable of 10 tons/year production of SOG (spun on glass)-Si has been in operation, and the trichlorosilane processing fluidized bed reactor has achieved its goals in performance and product quality. Element studies continue for the enlargement of the reactor unit for practical application and for the designing of a large plant of the commercially viable scale. In fiscal 1987, element studies are conducted for the enlargement of the reactor unit. Concerning the development of technologies for the manufacture of large reactor tubes strong enough to withstand practical application, efforts are made to strengthen materials for the fabrication of reactor element tubes (230mm and 500mm in diameter), to develop SiC-CVD (chemical vapor deposition) technology to provide reactor tube materials with resistance to corrosion, and to develop a single reactor tube structure indispensable for device enlargement. For the verification of such element technologies, in line with the study of experimental device operation capable of 10 tons/year SOG-Si production, studies are conducted on continuous stable operation technologies for the fluidized bed reactor, maintenance and improvement of product quality, and enhancement of durability of constituent parts and components.

    To determine the start-up processes, costs and consequences of community-directed treatment with ivermectin (CDTI) in two onchocerciasis endemic rural towns of Southeast Nigeria; namely Achi and Nike. The other objectives were to discover the community-financing mechanisms, local ivermectin distribution strategies and communities' organisational capacity to handle the programme. Structured questionnaires, informal interviews, observations, discussions with community members at general village assemblies and community outreach lectures were used at different stages of the study. The towns had the organisational capacity to implement the programme. Coverage with ivermectin was between 31-73% in Achi (mean = 58.6%), and 36.6-72% in Nike (mean = 61.95%). The unit financial costs were $0.17 in Nike and $0.13 in Achi, but the unit aggregate cost was $0.37 in Nike and $0.39 in Achi. When research costs were removed, the unit aggregate cost was $0.22 in Achi and $0.20 in Nike. Provider's financial costs and communities' non-financial costs were the biggest contributors to the aggregate cost. The cost would decrease in subsequent years since the research cost and parts of the mobilisation and training costs would not be incurred after the first year. Governments and sponsors of CDTI should find means of continuously strengthening the programme and providing technical support to the communities. As both CDTI and communities are dynamic entities, continuous health education campaigns are needed to keep reminding the people of the benefit of long-term ivermectin distribution, together with the need for community ownership of the programme.

    Radon (Rn-222) is a radioactive noble gas of natural origin that may be found anywhere in soil, air and different types of water: surface, borehole, well and spring. It is worth to carry out surveys for the radon in water for radiation protection as well as for geological considerations. The research presenters here was carried out in selected towns in and around Kumasi for the determination of radon concentration in groundwater. The major towns from which samples were taken are , Mowire, Kronum, Aburaso, Medoma, Kenyase, Buokrom, Bomfa, Ayeduase, Kotei, Tikrom. All the samples are used for domestic purposes such as cooking, drinking, bathing and washing. Waters from boreholes and wells in the selected towns were sampled and the radon concentration level measured. The Roll’s method was used for the radon concentration analysis on all the 100 samples. The results shows that, the minimum radon concentration in groundwater was 13015.934 Bq/m3 and it was found at Bomfa, and the highest was found to be 964628.480 Bq/m3, recorded at Mowire. It is believed that this variation of levels is mainly due to the difference in rock type, soil type and geology of the area as well as the depth of the water samples. This information can be used to estimate the possible health hazards from radon in the selected towns in the future from environmental point of view. The data would promote public awareness related to risk of radon exposure. (au)

    Excessive and uncontrollable worry is a defining feature of Generalized Anxiety Disorder (GAD). An important endeavor in the treatment of pathological worry is to understand why some people are unable to stop worrying once they have started. Worry perseveration is associated with a tendency to deploy goal-directed worry rules (known as “as many as can” worry rules; AMA). These require attention to the goal of the worry task and continuation of worry until the aims of the “worry bout” are achi...

    This paper describes the behavior of an Organic Rankine Cycle (ORC) fed by a heat source with adaptable temperature and mass flow. For a suitable choice of working fluid, the setting of its evaporation pressure is crucial for the performance of an ORC installation. The higher the evaporation pressure, the higher the cycle efficiency on the one hand, but the lower the energy recovered from the heat source due to a higher outlet temperature on the other hand. An optimum has to be found to achie...

    The preferred payment mechanism in a community financing scheme for local ivermectin distribution was elicited from randomly selected household heads from three communities in Nigeria using interviewer-administered structured questionnaires. The majority of the respondents in the three communities were prepared to pay for local ivermectin distribution. Additionally, the average amounts the respondents were prepared to pay per person treated ($0.28, $0.30 and $0.38 in Nike, Achi and Toro, respectively) were all more than the $0.20 ceiling recommended by the partners of the African Programme on Onchocerciasis Control (APOC). Thus, the cost-recovery outlook is bright in these communities. However, the preferred payment modality varied. Fee-for-service was the predominant payment modality in the Achi and Nike communities, while the Toro community preferred pre-payment. This study demonstrates that many communities have different payment preferences for endemic disease control efforts. This knowledge will help in developing acceptable and sustainable schemes. The imposition of unacceptable payment mechanisms will lead to an unwillingness to pay.

    2004-01-01

    The paper describes the PC based data station for stand-alone HIT ACHI F-2000 Spectrofluorimeter, for data acquisition, storage and analysis. The hardware link between the instrument and PC is made through RS232 serial port. The state of art software for control and data management is designed, developed and implemented in Visual Basic (Version 6). The software features on-screen editing of all operation parameters of the instrument and the operational control is achieved by Visual Basic command words communicated through serial port. Using this system, in addition to acquiring and storage of spectral data, it was possible to obtain the normalized absorption spectra of the samples. PC adapted Hitachi F-2000 Spectrofluorimeter can be successfully used for various operations such as photometric detection of UO22+ ions, recording of emission and excitation spectra and time evolution of fluorescence intensity on continuous UV irradiation. The data storage achieved through PC adaptation has also enabled recording of absorption spectra. (author)

  8. Traffic measurement for big network data

    CERN Document Server

    Chen, Shigang; Xiao, Qingjun

    2017-01-01

    This book presents several compact and fast methods for online traffic measurement of big network data. It describes challenges of online traffic measurement, discusses the state of the field, and provides an overview of the potential solutions to major problems. The authors introduce the problem of per-flow size measurement for big network data and present a fast and scalable counter architecture, called Counter Tree, which leverages a two-dimensional counter sharing scheme to achieve far better memory efficiency and significantly extend estimation range. Unlike traditional approaches to cardinality estimation problems that allocate a separated data structure (called estimator) for each flow, this book takes a different design path by viewing all the flows together as a whole: each flow is allocated with a virtual estimator, and these virtual estimators share a common memory space. A framework of virtual estimators is designed to apply the idea of sharing to an array of cardinality estimation solutions, achi...

  10. Magnetism basics and applications

    CERN Document Server

    Stefanita, Carmen-Gabriela

    2012-01-01

    This textbook is aimed at engineering students who are likely to come across magnetics applications in their professional practice. Whether designing lithography equipment containing ferromagnetic brushes, or detecting defects in aeronautics, some basic knowledge of 21st century magnetism is needed. From the magnetic tape on the pocket credit card to the read head in a personal computer, people run into magnetism in many products. Furthermore, in a variety of disciplines tools of the trade exploit magnetic principles, and many interdisciplinary laboratory research areas cross paths with magnetic phenomena that may seem mysterious to the untrained mind. Therefore, this course offers a broad coverage of magnetism topics encountered more often in this millenium, revealing key concepts on which many practical applications rest. Some traditional subjects in magnetism are discussed in the first half of the book, followed by areas likely to spark the curiosity of those more interested in today’s technological achi...

    The melanocortin system regulates an array of diverse physiological functions including pigmentation, feeding behavior, energy homeostasis, cardiovascular regulation, sexual function, and steroidogenesis. Endogenous melanocortin agonist ligands all possess the minimal messaging tetrapeptide sequence His-Phe-Arg-Trp. Based on this endogenous sequence, the Ac-His1-DPhe2-Arg3-Trp4-NH 2 tetrapeptide has previously been shown to be a useful scaffold when utilizing traditional positional scanning approaches to modify activity at the various melanocortin receptors (MC1-5R). The study reported herein was undertaken to evaluate a double simultaneous substitution strategy as an approach to further diversify the Ac-His1-DPhe2-Arg3-Trp4-NH 2 tetrapeptide with concurrent introduction of natural and unnatural amino acids at positions 1, 2, or 4 as well as an octanoyl residue at the N-terminus. The designed library includes the following combinations: (A) double simultaneous substitution at capping group position (Ac) together with position 1, 2, or 4, (B) double simultaneous substitution at position 1 and 2, (C) double simultaneous substitution at position 1 and 4, and (D) double simultaneous substitution at position 2 and 4. Several lead ligands with unique pharmacologies were discovered in the current study including antagonists targeting the neuronal mMC3R with minimal agonist activity and ligands with selective profiles for the various melanocortin subtypes. The results suggest that the double simultaneous substitution strategy is a suitable approach in altering melanocortin receptor potency, selectivity, or converting agonists into antagonists and vice versa.

  12. Management of electricity network cross border capacity: allocation procedures between France and Belgium

    Raytchev, D.

    2003-01-01

    This paper tries to identify a method of allocation of the Interconnector capacity for the transport of electricity which complies best with the (conflicting) interests of users, system operators and regulators in the context of a common European market of electricity. The first part combines a historical approach with a comparative study of existing allocation procedures to show that the new joint mechanism of auctioning and market splitting, applied to the whole northern zone of UCTE is vastly superior to the existing allocation arrangement on the Franco-Belgian border. The second part discusses some problems related to the implementation of the new allocation mechanism. Here we examine some difficulties concerning ca achy auctioning (like auction methods and organisation, profit distribution and derivative markets) as well as the market splitting method (neutrality, markets without power exchanges, etc). The main obstacle facing the new method remains however the lack of willingness to address the urgent issue of reforming the present allocation procedures- a remnant from the period of centrally planned electricity systems where neighbouring monopoly companies negotiated agreements of mutual assistance. These agreements are currently kept in place by tacit inaction despite their heterogeneity and arbitrariness which slow down the emergence of a real competition capable of contesting the positions of historic operators.

  13. Move! Eat better: Do you walk more than 10,000 steps a day?

    CERN Multimedia

    2013-01-01

    All of you who borrowed a pedometer from the Infirmary will confirm that it was a useful experience and that, in order to reach your recommended daily tally of 10,000 paces, you need to add about 30 minutes of exercise to your daily routine, which equates to about 4,000 extra paces. Why 10,000 steps?   The slogan “10,000 steps a day” comes from Japan. But the number wasn’t just pulled from a hat -  it’s based on a study by Dr Yoshiro Hatano. Walking is sacrosanct in Japanese society, where they use pedometers to determine the number of steps they walk every day. Dr Yoshiro Hatano has demonstrated that people who get enough walking in every day have improved health. In other words, you have to burn at least 200 extra calories per day, through exercise, in order to start reaping the benefits in terms of improved health. A 30-minute walk roughly corresponds to the 4,000 extra steps which are recommended but rarely taken. Is 10,000 steps an achie...

    Background: Migrants account for a large and growing proportion of tuberculosis (TB) cases in lowincidence countries in the European Union/European Economic Area (EU/EEA) which are primarily due to reactivation of latent TB infection (LTBI). Addressing LTBI among migrants will be critical to achi...... by the large pool of migrants with LTBI, poorly predictive tests, long treatments and a weak care cascade. Targeted LTBI programmes that ensure high screening uptake and treatment completion will have greatest individual and public health benefit....... to achieve TB elimination. Methods: We conducted a systematic review to determine effectiveness (performance of diagnostic tests, efficacy of treatment, uptake and completion of screening and treatment) and a second systematic review on cost-effectiveness of LTBI screening programmes for migrants living...... eligible for screening completed treatment because of losses along all steps of the LTBI care cascade. Limited economic analyses suggest that the most cost-effective approach may be targeting young migrants from high TB incidence countries. Discussion: The effectiveness of LTBI programmes is limited...

    2002-01-01

    An X-ray imaging detector has been developed for dental applications. The principle of this detector is based on application of a silicon charge coupled device covered by a scintillating wave-guide screen. Previous studies of such a detector showed promising results concerning the spatial resolution but low performance in terms of signal to noise ratio (SNR) and sensitivity. Recent results confirm the wave-guiding properties of the matrix and show improvement of the detector in terms of response uniformity, sensitivity and SNR. The present study is focussed on the fabrication of the scintillating screen where the principal idea is to fill a matrix of Si pores with a CsI scintillator. The photoluminescence technique was used to prove the wave-guiding property of the matrix and to inspect the filling uniformity of the pores. The final detector was characterized by X-ray evaluation in terms of spatial resolution, light output and SNR. A sensor with a spatial resolution of 9 LP/mm and a SNR over 50 has been achie...

    2013-01-01

    A new fixed-target experiment at the CERN SPS accelerator is proposed that will use decays of charm mesons to search for Heavy Neutral Leptons (HNLs), which are right-handed partners of the Standard Model neutrinos. The existence of such particles is strongly motivated by theory, as they can simultaneously explain the baryon asymmetry of the Universe, account for the pattern of neutrino masses and oscillations and provide a Dark Matter candidate. Cosmological constraints on the properties of HNLs now indicate that the majority of the interesting parameter space for such particles was beyond the reach of the previous searches at the PS191, BEBC, CHARM, CCFR and NuTeV experiments. For HNLs with mass below 2 GeV, the proposed experiment will improve on the sensitivity of previous searches by four orders of magnitude and will cover a major fraction of the parameter space favoured by theoretical models. The experiment requires a 400 GeV proton beam from the SPS with a total of 2x10^20 protons on target, achie...

    1995-01-01

    Few books on software project management have been as influential and timeless as The Mythical Man-Month. With a blend of software engineering facts and thought-provoking opinions, Fred Brooks offers insight for anyone managing complex projects. These essays draw from his experience as project manager for the IBM System/360 computer family and then for OS/360, its massive software system. Now, 20 years after the initial publication of his book, Brooks has revisited his original ideas and added new thoughts and advice, both for readers already familiar with his work and for readers discovering it for the first time. The added chapters contain (1) a crisp condensation of all the propositions asserted in the original book, including Brooks' central argument in The Mythical Man-Month: that large programming projects suffer management problems different from small ones due to the division of labor; that the conceptual integrity of the product is therefore critical; and that it is difficult but possible to achi...

  20. Realization of an X-Band RF System for LCLS

    CERN Document Server

    McIntosh, Peter; Brooks, William; Emma, Paul; Rago, Carl

    2005-01-01

    A single X-band (11.424 GHz) accelerating structure is to be incorporated in the LCLS Linac design to linearize the energy-time correlation (or gradient) across each bunch, features which originate in the preceding accelerating structures (L0 and L1). This harmonic RF system will operate near the negative RF crest to decelerate the beam, reducing these non-linear components of the correlation, providing a more efficient compression in the downstream bunch compressor chicanes (BC1 and BC2). These non-linear correlation components, if allowed to grow, would lead to Coherent Synchrotron Radiation (CSR) instabilities in the chicanes, effectively destroying the coherence of the photon radiation in the main LCLS undulator. The many years devoted at SLAC in the development of X-band RF components for the NLC/JLC linear collider project, has enabled the technical and financial realization of such an RF system for LCLS. This paper details the requirements for the X-band system and the proposed scheme planned for achie...

    2017-09-01

    This two-part study comprised two descriptive, cross-sectional surveys to evaluate treatment satisfaction among patients with systemic lupus erythematosus (SLE) and their physicians from US clinical practices. The Lupus Plus Project (LPP; part one) involved belimumab-containing regimens; the Disease Specific Program (DSP; part two) included all treatments and was designed to build on the body of evidence from part one. The LPP recruited patients receiving belimumab, and comprised 2 paper questionnaires: a patient self-completion questionnaire (PSC) and a patient record form (PRF) completed by the physician. The DSP enrolled patients with SLE receiving any treatment and comprised four parts: a PSC, a PRF completed by the physician after patient consultation, face-to-face physician interviews, and a workload form completed by the physicians to indicate their total SLE patient workload. The key objective of this study was to assess physician and patient satisfaction with current treatment. From the PSCs, data regarding patient-reported satisfaction with current treatment were available for 263 patients who were receiving belimumab combination therapy (LPP) and 250 patients who were receiving non-belimumab treatment (DSP). The majority of patients (belimumab, 86.3% [227/263]; non-belimumab, 78.4% [196/250]) responded positively (at least "somewhat satisfied") when asked about current treatment satisfaction, as did physicians (belimumab, 82.9% [311/375]; non-belimumab, 74.3% [326/439]). In multivariate analysis, factors most strongly associated with patient-reported satisfaction for patients receiving belimumab were patient-reported improvements in leisure activities since taking belimumab (odds ratio [OR] = 4.66), physician-reported improvements in fatigue (OR = 3.72), patient-reported improvements in general symptoms (OR = 3.02), and pain/achiness (OR = 2.71). Physician satisfaction was associated with clinical outcome such as improvements in pain/achiness (OR = 6

    Full Text Available This research aims to study the prevention law of gambling in Aceh. Which has applied since 2003 M. The problem appears from this study is miss understanding of some Achiness society. Some of them accept that the gambling law is applied according to the purpose of Islam on the prohibit gambling. On another perception some of the community in Aceh do not accept it. they argue that the law of prevention gambling in Aceh is just from government not from Syari’. The explanation of appropriation between the purpose of government on applying this law and the purpose of maqashid al- syariah on prevention gambling. And discuss the reason of miss understanding society. So, this research will analyse the problems deal from this law, the solution, and finding out the wisdom of forbid gambling, and the relation prevention gambling law and the maqashid al – syariah on keep the wealth, because the command of preserve wealth is one of the purpose of syariah that Muslim should watch over it.thus, The researcher adopted the inductive methodology and the analytical approach to reach the solution on it. The most important result finding in this study is firm relation between the prevention gambling law in Aceh and maqashid al- syariah. Gambling is prohibited by many evidences and propositions from al-qur’an and hadits. In addition There are many kind of gambling renowned, the punishment for violate the gambling law is ta’ziriah. This forbidden relate to the command on keeping the wealth. Since that is one of the purpose of shariah. If the prevention of gambling law is approved and applied so that the purpose of shariah is reached as well. Futhermore, the law must be holdout on all Muslims to avoid gambling .

    We present a searchable repository of codes of ethics and standards in health informatics. It is built using state-of-the-art search algorithms and technologies. The repository will be potentially beneficial for public health practitioners, researchers, and software developers in finding and comparing ethics topics of interest. Public health clinics, clinicians, and researchers can use the repository platform as a one-stop reference for various ethics codes and standards. In addition, the repository interface is built for easy navigation, fast search, and side-by-side comparative reading of documents. Our selection criteria for codes and standards are two-fold; firstly, to maintain intellectual property rights, we index only codes and standards freely available on the internet. Secondly, major international, regional, and national health informatics bodies across the globe are surveyed with the aim of understanding the landscape in this domain. We also look at prevalent technical standards in health informatics from major bodies such as the International Standards Organization (ISO) and the U. S. Food and Drug Administration (FDA). Our repository contains codes of ethics from the International Medical Informatics Association (IMIA), the iHealth Coalition (iHC), the American Health Information Management Association (AHIMA), the Australasian College of Health Informatics (ACHI), the British Computer Society (BCS), and the UK Council for Health Informatics Professions (UKCHIP), with room for adding more in the future. Our major contribution is enhancing the findability of codes and standards related to health informatics ethics by compilation and unified access through the health informatics ethics repository.

  6. Structure-activity relationships of the melanocortin tetrapeptide Ac-His-DPhe-Arg-Trp-NH2 at the mouse melanocortin receptors. Part 3: modifications at the Arg position.

    2003-01-01

    The melanocortin pathway is involved in the regulation of several physiological functions including skin pigmentation, steroidogenesis, obesity, energy homeostasis, and exocrine gland function. This melanocortin pathway consists of five known G-protein coupled receptors, endogenous agonists derived from the proopiomelanocortin (POMC) gene transcript, the endogenous antagonists Agouti and the Agouti-related protein (AGRP) and signals through the intracellular cAMP signal transduction pathway. The melanocortin-3 receptor (MC3R) and melanocortin-4 receptor (MC4R) located in the brain are implicated as participating in the metabolic and food intake aspects of energy homeostasis and are stimulated by melanocortin agonists such as alpha-melanocyte stimulation hormone (alpha-MSH). All the endogenous (POMC-derived) melanocortin agonists contain the putative message sequence "His-Phe-Arg-Trp." Herein, we report 12 tetrapeptides, based upon the template Ac-His(6)-DPhe(7)-Arg(8)-Trp(9)-NH(2) (alpha-MSH numbering) that have been modified at the Arg(8) position by neutral, basic, or acidic amino acid side chains. These peptides have been pharmacologically characterized for agonist activity at the mouse melanocortin receptors MC1R, MC3R, MC4R, and MC5R. The most notable results of this study include the observation that removal of the guanidinyl side chain moiety results in decreased melanocortin receptor potency, but that this Arg(8) side chain is not critical for melanocortin receptor agonist activity. Additionally, incorporation of the homoArg(8) residue results in 56-fold MC4R versus MC3R selectivity, and the Orn(8) residue results in 123-fold MC4R versus MC5R and 63-fold MC5R versus MC3R selectivity.

    The Australian and New Zealand Audit of Surgical Mortality (ANZASM) National Report 2015 found that within the cohort of audited deaths, 85% were emergencies with acute life-threatening conditions, and by far, the most common procedures were laparotomy and colorectal procedures. Emergency laparotomy outcomes have shown improvement through audit and reporting in the UK. The purpose of this study was to determine the outcome of emergency laparotomy in the state of Victoria, Australia. The Dr Foster Quality Investigator (DFQI) database was interrogated for a set of Australian Classification of Health Intervention (ACHI) codes defined by the authors as representing an emergency laparotomy. The dataset included patients who underwent emergency laparotomy from July 2007 to July 2016 in all Victorian hospitals. There were 23,115 emergency laparotomies conducted over 9 years in 66 hospitals. Inpatient mortality was 2036/23,115 (8.8%). Mortality in the adult population increased with age and reached 18.1% in those patients that were 80 years or older. 51.3% were females, and there was no significant difference in survival between genders. Patients with no recorded comorbidities had a mortality of 4.3%, whereas those with > 5 comorbidities had 19.3% mortality. Administrative data accessed via a tool such as DFQI can provide useful population data to guide further evidence-based improvement strategies. The mortality for emergency laparotomy within Victorian hospitals is comparable, if not better than that seen in overseas studies. There is a need to continue routine audit of mortality rates and implement systems improvement where necessary.

Physycal education is important factor of overall education. It becomes equal and equally valuable process, which features special tools and tasks. However, besides everything else success of physical education of children and youth depends on methods, content, tools, sources and school organization of teaching. The science has universal deve- lopment of the personality as the main goal. Following that every education which’s results The science puts overall development of personality as goal of education. Follo- wing that, every education that opposes to that goal is wrong and narrow. This means that physical education as composing and indivisible part of general education is permanent, planned and systematic process of impact on human, especially at the period of youth when different kinds of tools, especially by physical education develop and build a person capable for work, and when forming his personality in sense of ethics Yet, besides all other a success of physical education of children and youth depend on methods, content, tools, sources and school organization of teaching. For an achie- vement of expected results it is not enough that teacher knows only meanings, aims and connectivity of his work in function of school as educational institution, but also to know to organize and perform teaching by modern scientific achievement, specially pedagogy, psychology and physiology.

    Acetaminophen is frequently prescribed for treating patients with the common cold, but there is little evidence as to whether it is effective. To determine the efficacy and safety of acetaminophen in the treatment of the common cold in adults. We searched CENTRAL 2013, Issue 1, Ovid MEDLINE (1950 to January week 5, 2013), EMBASE (1980 to February 2013), CINAHL (1982 to February 2013) and LILACS (1985 to February 2013). We included randomised controlled trials (RCTs) comparing acetaminophen to placebo or no treatment in adults with the common cold. Studies were included if the trials used acetaminophen as one ingredient of a combination therapy. We excluded studies in which the participants had complications. Primary outcomes included subjective symptom score and duration of common cold symptoms. Secondary outcomes were overall well being, adverse events and financial costs. Two review authors independently screened studies for inclusion, assessed risk of bias and extracted data. We performed standard statistical analyses. We included four RCTs involving 758 participants. We did not pool data because of heterogeneity in study designs, outcomes and time points. The studies provided sparse information about effects longer than a few hours, as three of four included studies were short trials of only four to six hours. Participants treated with acetaminophen had significant improvements in nasal obstruction in two of the four studies. One study showed that acetaminophen was superior to placebo in decreasing rhinorrhoea severity, but was not superior for treating sneezing and coughing. Acetaminophen did not improve sore throat or malaise in two of the four studies. Results were inconsistent for some symptoms. Two studies showed that headache and achiness improved more in the acetaminophen group than in the placebo group, while one study showed no difference between the acetaminophen and placebo group. None of the included studies reported the duration of common cold

    Full Text Available OBJETIVO: Identificar y documentar las barreras de acceso a los servicios de salud en la población indígena de Rabinal en Guatemala. MATERIAL Y MÉTODOS: Se privilegió el análisis cualitativo y la recopilación de datos se realizó en Rabinal durante dos meses (Guatemala. Se realizaron quince entrevistas semi dirigidas a indígenas achís y cinco entrevistas a profesionales de la salud. Un grupo de discusión fue formado para validar la información recogida durante las entrevistas individuales; la retranscripción de éstas y la compilación de los datos permitieron hacer el análisis de contenido. RESULTADOS: Las barreras de acceso están interrelacionadas y las barreras geográficas están relacionadas con la distancia y con la escasez de transporte; las barreras económicas son los precios de las consultas y de los medicamentos, además, entre las barreras culturales, la lengua española es un obstáculo. Los indígenas tienen otra concepción de la medicina y de los tratamientos y se quejan en ocasiones de trato abusivo por parte de los profesionales sanitarios. A su vez, los profesionales de la salud reconocen que el trauma de la guerra está presente y critican las malas condiciones de vida y la falta de recursos. CONCLUSIONES: Los servicios de salud no son adecuados ni suficientes para responder a las necesidades de la población local.OBJECTIVE: To identify and document access barriers to health care services for the indigenous population in Rabinal, Guatemala. MATERIAL AND METHODS: A qualitative analysis was used. Over a period of two months, 20 semi-directional interviews were conducted in Rabinal, Guatemala: 15 with Achis indigenous people and five with health professionals. A focus group was done to verify the information collected during the individual interviews. The qualitative analysis was based on the transcription of interviews and the compilation of the data. RESULTS: Barriers to access are inter-relational. Geographic
