    This booklet is based on the findings of an infiltration analysis for supermarkets and large retail buildings without refrigerated cases. It enables retail building managers and engineers to calculate the energy savings potential for vestibule additions for supermarkets; and bay door operation changes in large retail stores without refrigerated cases. Retail managers can use initial estimates to decide whether to engage vendors or contractors of vestibules for pricing or site-specific analyses, or to decide whether to test bay door operation changes in pilot stores, respectively.

    2015-01-01

    From 6 July to 31 October 2015, the GS department will be carrying out renovation work on the car park next to Buildings 4 and 5. This work is aimed at improving safety on and around the car park for all users, particularly children attending the nursery school, pedestrians and cyclists.   Layout of the upcoming car park.   The work on the car park will be conducted in two stages so that half of the parking spaces will always be available, in order to limit the impact on users as much as possible (the closed-off areas will be clearly indicated). When the work is completed, the car park will have been completely renovated, with new surfacing and road markings, high-quality lighting and more parking spaces (+5%). During the work, part of the car park will be inaccessible, which is likely to make it more difficult to find a parking space. We therefore invite you to park in the Globe car park during this period. The renovation work will also affect Entrance A (Route Bell), which will be fitt...

    The booming natural gas market in the Marcellus shale region has seen the appearance of many oil and gas processing stations, the latter generating a great deal of noise, which disturbs local residents. The oil and gas companies have therefore developed a patchwork of noise reduction techniques, from basic mufflers to engineered, sound-proof buildings. This paper focuses on a compromise: a gas compressor station, located in Lycoming County, Pennsylvania, encased in a light-weight, metal building with switch-back air inlet openings for cooling and noise reduction. This case study aims to measure the noise emissions of the compressor, and possibly propose solutions for its mitigation. Since Lycoming County has a fairly stringent policy on noise disturbance, especially for low-frequency sounds, noise emission results showed that switch-back openings and the walls of the compressor building must be mitigated and that action must be taken by the gas company to meet the noise ordinance requirements.

  14. Thermonuclear operation mode and entrance/exit monitoring system

    International Nuclear Information System (INIS)

    The present invention provides a processing system when the entrance/exit of each of buildings or chambers are monitored based on contents of control for the equipments in each operation mode of a thermonuclear experimental device, and provides a processing system when abnormalities are detected in an early stage. Namely, interlock signals for on-off conditions or each of the entrance/exit in each operation mode are inputted to a control device. With such procedures, contents of processing at entrance/exit of a power source building, an experimental building, and a main chamber in a certain operation mode (on-off condition, etc.) are determined, and the logic can be reflected on the control device. According to the present invention, a safety system for the operation can be ensured sufficiently, coping with increased scale of the thermonuclear experimental device, complication of the control system or temporary change of the operation control system.

    In 1999, the U. S. Department of Energy (DOE) awarded a Cooperative Agreement to Texaco Energy Systems Inc. to provide a preliminary engineering design of an Early Entrance Coproduction Plant (EECP). Since the award, continuous and diligent work has been undertaken to achieve the design of an economical facility that makes strides toward attaining the goal of DOE's Vision 21 Program. The objective of the EECP is to convert coal and/or petroleum coke to power while coproducing transportation fuels, chemicals, and useful utilities such as steam. This objective is being pursued in a three-phase effort through the partnership of the DOE with prime contractor Texaco Energy Systems, LLC. (TES), the successor to Texaco Energy Systems, Inc. The key subcontractors to TES include General Electric (GE), Praxair, and Kellogg Brown and Root. ChevronTexaco provided gasification technology and Rentech Inc.'s Fischer-Tropsch (F-T) technology that has been developed for non-natural gas sources. GE provided gas turbine technology for the combustion of low energy content gas. Praxair provided air separation technology and KBR provided engineering to integrate the facility. A conceptual design was completed in Phase I and the report was accepted by the DOE in May 2001. The Phase I work identified risks and critical research, development, and testing that would improve the probability of technical success of the EECP. The objective of Phase II was to mitigate the risks by executing research, development, and testing. Results from the Phase II work are the subject of this report. As the work of Phase II concluded, it became evident that sufficient, but not necessarily complete, technical information and data would be available to begin Phase III - Preliminary Engineering Design. Work in Phase II requires additional technical development work to correctly apply technology at a specific site. The project's intended result is to provide the necessary technical, economic, and

    The 1999 U. S. Department of Energy (DOE) award to Texaco Energy Systems Inc. (presently Texaco Energy Systems LLC, a subsidiary of ChevronTexaco) was made to provide a Preliminary Engineering Design of an Early Entrance Coproduction Plant (EECP). Since the award presentation, work has been undertaken to achieve an economical concept design that makes strides toward the DOE Vision 21 goal. The objective of the EECP is to convert coal and/or petroleum coke to electric power plus transportation fuels, chemicals and useful utilities such as steam. The use of petroleum coke was added as a fuel to reduce the cost of feedstock and also to increase the probability of commercial implementation of the EECP concept. This objective has been pursued in a three phase effort through the partnership of the DOE with prime contractor Texaco Energy Systems LLC and subcontractors General Electric (GE), Praxair, and Kellogg Brown and Root (KBR). ChevronTexaco is providing gasification technology and Rentech's Fischer-Tropsch technology that has been developed for non-natural gas feed sources. GE is providing gas turbine technology for the combustion of low energy content gas. Praxair is providing air separation technology, and KBR is providing engineering to integrate the facility. The objective of Phase I was to determine the feasibility and define the concept for the EECP located at a specific site; develop a Research, Development, and Testing (RD&T) Plan to mitigate technical risks and barriers; and prepare a Preliminary Project Financing Plan. The objective of Phase II is to implement the work as outlined in the Phase I RD&T Plan to enhance the development and commercial acceptance of coproduction technology. The objective of Phase III is to develop an engineering design package and a financing and testing plan for an EECP located at a specific site. Phase I Preliminary Concept Report was completed in 2000. The Phase I Preliminary Concept Report was prepared based on making

    International Nuclear Information System (INIS)

    This study evaluates alternatives for utility service entrances to the repository. We determined the requirements for a repository utility supply. These requirements were defined as safety, maintainability, flexibility, reliability, cost efficiency, voltage regulation, and simplicity of operation. The study showed that repository shafts can best satisfy all requirements for location of the utility supply without the use of borehole penetrations into the repository. It is recommended that the shafts be utilized for utility distribution to the repository, and that the current NWTS program position to minimize the number of boreholes penetrating the repository horizon be maintained. 42 refs., 2 figs., 3 tabs

    In order to study the effect of inlet port on the pump performance, the impeller inlet part, should be analyzed for impeller is able to extend the function of water flow to the front of the impeller for a long distance. Impeller flow of pre swirl flow is due to selection of least resistance into the impeller, but the pre swirl in the flow direction according to the impeller blade entrance angle, and the circumferential velocity of flow. The study found that lies in the external characteristic of the pump will be fell when the off-design, but in the case of large flow impeller and impeller in the direction of the front entrance fluid pre whirl steering is on the contrary, when this with little traffic is quite different .this article will study the occurrence, development, and the mechanism of the influence of flow field.

  1. [Furcation entrance dimension, divergent angle and length of CEJ to furcation entrance relate to periodontal therapy].

    Science.gov (United States)

    Hou, G L; Chen, S F; Tsai, C C

    1996-12-01

    In previous studies we have investigated the furcation entrance dimension (FED), furcation entrance angle (FEA) and the distance between cementoenamel junction and furcation entrance (CEJ-FE) of the first and second molars and compared the Chinese with the Caucasians. The aim of the present study was to relate the FED, FEA, and distance of CEJ-FE to the clinical significance of periodontal therapy of molar furcations. All the FEDs, FEAs, and distance of CEJ-FEs of the molars were measured by a stereomicroscope equipped with a Bioscan OPTIMAS Image Analyzer and statistically analyzed by Student's paired t-test, multiple regression of ANOVA and correlation analysis. The results are summarized below. (1) There is a significant relationship between FEA and location of buccal, mesial, and distal furcations of maxillary first and second molars (16& 26, p < 0.001; 17&27, p < 0.01). (2) There exists a significant relationship between FEA and FED in the mandibular first and second molars. (3) There exists a significant relationship between FED and FEA in the mandibular second molar (r = 0.370, p < 0.05). (4) The prevalence of mean FED and FEA (type D, FED < or = 0.75 mm and FEA < or = 90 degree) of the maxillary first molar (45%) is twice as high as the maxillary first molar (24%). (5) The prevalence of type D of the buccal (32%) and lingual (37%) furcations on the mandibular second molar is markedly higher than the first molar (buccal = 12%; lingual = 4%, respectively). These results reveal that those topographics of the FED, FEA, and distance of CEJ-FE in second molars have poor prognosis in periodontal therapy when compared with first molars. PMID:9011129

    Stingless bees (Meliponini) construct their own species-specific nest entrance. The size of this entrance is under conflicting selective pressures. Smaller entrances are easier to defend; however, a larger entrance accommodates heavier forager traffic. Using a comparative approach with 26 species of stingless bees, we show that species with greater foraging traffic have significantly larger entrances. Such a strong correlation between relative entrance area and traffic across the different species strongly suggests a trade-off between traffic and security. Additionally, we report on a significant trend for higher forager traffic to be associated with more guards and for those guards to be more aggressive. Finally, we discuss the nest entrance of Partamona, known in Brazil as boca de sapo, or toad mouth, which has a wide outer entrance but a narrow inner entrance. This extraordinary design allows these bees to finesse the defensivity/traffic trade-off. PMID:18021200

    1994-08-01

    The purpose of the present study was to document the furcation entrance dimensions (FEDs) of the maxillary and mandibular 1st and 2nd molars and relate them to the choice of periodontal therapy. Study samples consisted of 89 maxillary molars (49 1st and 40 2nd molars) and 93 mandibular molars (50 1st and 43 2nd molars). All the FEDs of the molars were examined and measured under a stereomicroscope at 2.5 x equipped with a Bioscan OPTIMAS Image Analyzer (BOIA). The results may be summarized as follows. (1) The mean FEDs in the buccal, distal and mesial furcations of maxillary 1st and 2nd molars were 0.74 mm, 0.99 mm and 1.04 mm in the 1st molars, and 0.63 mm, 0.67 mm, 0.90 mm in the 2nd molars, respectively. In the buccal and lingual furcations of mandibular 1st and 2nd molars, they measured 0.88 mm and 0.81 mm, and 0.73 mm and 0.71 mm, respectively. (2) The %s of FEDs of 0.56 mm or less (the tip width of a Cavitron tip being 0.56 mm) in the buccal, distal and mesial furcations of maxillary 1st and 2nd molars, accounted for 32%, 8% and 6% of 1st molars, and 40%, 40% and 18% of 2nd molars. In the buccal and lingual areas of mandibular 1st and 2nd molars, they accounted for 16% and 26%, and 35% and 33% of the furcations, respectively.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7929856

  15. An extra push from entrance-channel effects

    OpenAIRE

    N.Rowley; Grar, N.; Hagino, K.

    2005-01-01

    Symmetric heavy-ion collisions are known to display an `extra-push' effect. That is, the energy at which the s-wave transmission is 0.5 lies significantly higher than the nominal Coulomb barrier. Despite this, however, the capture cross section is still greatly enhanced below the uncoupled barrier. It is shown that this phenomenon can be simply explained in terms of entrance-channel effects which account for long-range Coulomb excitations.

    1999-01-01

    The entrance channel effect was studied for the decay of sup 1 sup 7 sup 0 W formed in fusion reactions with different beam-target combinations. The average number of emitted neutrons suggest a lower effective excitation energy in the (alpha,xn) decay channel when more mass-symmetric reaction is used, especially at the highest angular momenta. The results are in qualitative agreement with predictions of the dissipative fusion model.

  17. Entrance channel effect in the incomplete fusion reactions

    International Nuclear Information System (INIS)

    In the present work the effect of various entrance channel parameters on incomplete fusion strength and the reaction dynamics in 12C+159Tb system at energies ∼ 4-7 MeV/A have been investigated by measuring the excitation functions of individual reaction channels. Experimental excitation functions have been analyzed in the framework of compound nucleus decay using statistical model code PACE4. Analysis of data suggests the production of xn/pxn-channels via complete fusion of 12C with 159Tb, as these are found to be well reproduced by PACE4 predictions, while, a significant enhancement in the excitation functions of α-emitting channels has been observed over the theoretical ones. This enhancement has been attributed due to incomplete fusion. For better insight into the underlying dynamics, the fraction of incomplete fusion to the total fusion has been deduced and compared with 16O+159Tb and other nearby systems as a function of various entrance channel parameters. The fraction of incomplete fusion has been found to be sensitive to the projectile type, energy and entrance-channel mass-asymmetry. (authors)

  20. Evaluation of entrance surface air kerma in pediatric chest radiography

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate the entrance surface air kerma in pediatric chest radiography. An evaluation of 301 radiographical examinations in anterior–posterior (AP) and posterior–anterior (PA) (166 examinations) and lateral (LAT) (135 examinations) projections was performed. The analyses were performed on patients grouped by age; the groups included ages 0–1 y, 1–5 y, 5–10 y, and 10–15 y. The entrance surface air kerma was determined with DoseCal software (Radiological Protection Center of Saint George's Hospital, London) and thermoluminescent dosimeters. Two different exposure techniques were compared. The doses received by patients who had undergone LAT examinations were 40% higher, on average, those in AP/PA examinations because of the difference in tube voltage. A large high-dose “tail” was observed for children up to 5 y old. An increase in tube potential and corresponding decrease in current lead to a significant dose reduction. The difference between the average dose values for different age ranges was not practically observed, implying that the exposure techniques are still not optimal. Exposure doses received using the higher tube voltage and lower current-time product correspond to the international diagnostic reference levels. - Highlights: • The entrance surface air kerma of chest X-ray examinations in pediatric patients was estimated. • The data were analyzed for patients aged up to 15 y, stratified by age. • The doses of LAT examinations were 40% higher than of AP/PA because of kV used. • An increase in kV with a decrease in mAs leads to significant dose reduction

    2016-01-01

    A combined dynamical model using concept of dinuclear systems (DNS) and one-dimensional (1D) Langevin equations was applied to investigate the effect of entrance channel on dynamics of heavy ions collision. The 30Si+170Er, 16O+184W and 19F+181Ta reactions which formed the compound nucleus 200Pb have been considered to study this effect. We studied these reactions dynamically and calculated the ratio of evaporation residue cross-section to fusion cross-section (σER/σFus) as a tool for investigation of entrance channel effect. Results of combined model are compared with available experimental data and results of 1D Langevin equations. Obtained results based on combined model are in better agreement with experimental data in comparison with results of Langevin equations. We concluded for 30Si+170Er and 19F+181Ta reactions the results of combined model that support the quasi-fission process are different relative to Langevin dynamical approach, whereas for 16O+184W system the two models give similar results.

  6. Why ions enter the sheath entrance at supersonic speed?

    Science.gov (United States)

    Tang, Xianzhu; Guo, Zehua

    2015-11-01

    In a boundary plasma of a fusion device, the sheath Knudsen number, which is defined as the ratio of the plasma mean-free-path and the plasma Debye length, is much greater than unity, so one anticipates a collisionless sheath, even though the overall boundary plasma in the scrape-off layer is collisional. This is supposed to be the regime for which the Bohm criteria for the ion entry flow at the sheath entrance, v >=cs with cs the sound speed, is usually satisfied at the equal sign. But numerical simulations using first-principles particle-in-cell codes tend to report a supersonic flow. Here we revisit the two-scale and transition layer analysis of the sheath-presheath transition, in tandem with the conventional Bohm criteria analysis, to understand why and how the supersonic sheath entry flow is established at the sheath entrance, which is a few Debye length away from the wall, and its impact on plasma particle and power load at the wall.

  7. Heat transfer to liquid sodium in the thermal entrance region

    International Nuclear Information System (INIS)

    It is well known that the convective heat transfer in the regions of duct systems where the thermal boundary layers are not yet established can be far superior to heat transfer in the fully developed regions. A quantitative understanding of heat transfer in the thermal entrance region is essential in designing high heat-flux nuclear reactors. More specifically, if the thermal boundary layers have not been fully established in the system, the forced-convection relations for the fully developed regions cannot be used to predict the heat transfer characteristics. The present work is characterized by the following: 1. The behaviours in the thermal entrance region have been examined more completely. 2. To obtain a higher accuracy of analyses, in present study the method of SPARROW et al. for pipe was improved for annulus by utilizing a finite difference technique. Furthermore, an asymptotic solution was developed. 3. This is, in our knowledge, the first experimental investigation about the thermal development effect on turbulent heat transfer from rod element to liquid sodium in annulus with fully developed flow.

  9. Entrance, exit, and reentrance of one shot with a shotgun

    DEFF Research Database (Denmark)

    Gulmann, C; Hougen, H P

    1999-01-01

    The case being reported is one of a homicidal shotgun fatality with an unusual wound pattern. A 34-year-old man was shot at close range with a 12-gauge shotgun armed with No. 5 birdshot ammunition. The shot entered the left axillary region, exited through the left infraclavicular region, and...... thereafter penetrated the left side of the neck, causing tearing of the left common carotid artery and the right internal carotid artery. The entrance wound in the axilla was larger than the other wounds, and before autopsy it was believed that the shotgun had been fired twice, causing one wound in the neck...... and one wound perforating the infraclavicular region and exiting through the left axillary region. Thus, this case shows that unusual wound patterns in shotgun fatalities can easily lead to incorrect assumptions with regard to number and direction of shots fired unless thorough investigation is...

  14. Determination of Entrance Skin Doses and Organ Doses for Medical X Ray Examinations

    International Nuclear Information System (INIS)

    A national survey of patient doses for diagnostic X ray radiographs is planned in Taiwan. Entrance skin doses and organ doses for all installed X ray machines will be investigated. A pilot study has been carried out for the national survey to develop a protocol for the dose assessment. Entrance skin doses and organ doses were measured by thermoluminescence dosemeters and calculated by Monte Carlo simulations for several X ray examinations. The conversion factor from free air entrance absorbed dose to entrance skin dose was derived. A formula for the computation of entrance skin doses from inputs of kVp, mA.s, source to skin distance, aluminium filtration, and generator rectifying was constructed. Organ doses were measured using a RANDO phantom and calculated using a mathematical phantom. All data will be passed to the Atomic Energy Council for developing a programme of national survey and regulatory controls for diagnostic X ray examinations. (author)

  15. Entrance channel effects in fusion reactions near the barrier: Reaction dynamics or nuclear structure?

    International Nuclear Information System (INIS)

    The origin of previously reported entrance channel effects by symmetric and asymmetric fusion reactions leading to rare earth nuclei near the Coulomb barrier is critically reviewed. Possible influences of reaction dynamics or structure effects due to the proximity of superdeformation are discussed using new charged-particle spectra and angular distributions associated with specific axn exit channels. For axn channels, nonstatistical effects in the fusion of the asymmetric entrance channel are responsible for the large difference in the spin distributions in the evaporation residues formed by symmetric and asymmetric entrance channels. Whereas GDR spectra show significant entrance channel effects, the authors find no influence on the subbarrier α spectra from possible elongated shapes associated with early reaction dynamics. New data and analyses of γ-ray multiplicity distributions from the xn exit channels show that previously reported entrance channel effects are due to mapping from l to residue spin and then to γ-ray multiplicity

  16. Entrance radiation dose determination for selected cancer patients at the Lagos University Teaching Hospital, Nigeria

    International Nuclear Information System (INIS)

    Aim: To assess the precision of radiation dose delivery to Radiotherapy cancer patients at the Lagos University Teaching Hospital (LUTH), Nigeria. Method and materials: Entrance doses for breast, cervical, prostate and head and neck cancer patients were determined using in-vivo thermo-luminescent dosimetry (TLD) technique. Total number of patients admitted for this study is 30. The TLDs were divided into four groups; breast (10), cervical (10), head and neck (5) and prostate (5). Two TLD chips were placed on each patient to obtain the average value. The patients were treated under normal conditions with TLD detectors placed at suitable points in the beam on the patient's skin, under a dose build-up material. The ELEKTA clinical linear accelerator (LINAC) available at the LINAC Center of our Radiotherapy Department served as the source of the 6 MV photon beam. Results: The results showed that 27 of 30 patients admitted were within ±5% of the recommended international limit. Prostate and cervical patients had doses within the range of the limit. Two of the breast patients were −5.05% and −5.88%. The maximum value of −6.01% was recorded in one of the head and neck treatments. Conclusions: This study was part of efforts to optimize patient dose in our radiotherapy center. It has given us a preliminary description of the current practice of radiotherapy in this institution. The values obtained show no major differences from similar studies reported in the literature

    2014-09-15

    Our recent works [K. Lan et al., Phys. Plasmas 21, 010704 (2014); K. Lan et al., Phys. Plasmas 21, 052704 (2014)] have shown that the octahedral spherical hohlraums are superior to the cylindrical hohlraums in both higher symmetry during the capsule implosion and lower backscatter without supplementary technology. However, both the coupling efficiency from the drive laser energy to the capsule and the capsule symmetry decrease remarkably when larger laser entrance holes (LEHs) are used. In addition, the laser beams injected at angles > 45° transport close to the hohlraum wall, thus the wall blowoff causes the LEH to close faster and results in strong laser plasma interactions inside the spherical hohlraums. In this letter, we propose a novel octahedral hohlraum with LEH shields and cylindrical LEHs to alleviate these problems. From our theoretical study, with the LEH shields, the laser coupling efficiency is significantly increased and the capsule symmetry is remarkably improved in the spherical hohlraums. The cylindrical LEHs take advantage of the cylindrical hohlraum near the LEH and mitigate the influence of the blowoff on laser transport inside a spherical hohlraum. The cylindrical LEHs can also be applied to the rugby and elliptical hohlraums.

    Full text: Of the various techniques that can be used for personnel dosimetry, thermoluminescence dosimetry (TLD) has emerged as a superior technique due to its manifold advantages over other methods of dose estimation. Various phosphors have been therefore investigated regarding their suitability for dosimetry. In this paper, a dosimetry system based on thermally stimulated luminescence (TSL) from zirconium oxide phosphors embedded in polytetrafluorethylene (ZrO{sub 2}+PTFE) was developed for entrance surface doses (ES) measurements in mammography. Small ZrO{sub 2} pellets of 5 mm in diameter and 0.8 mm in thickness were used. The reproducibility of measurements and linearity of ZrO{sub 2} were also studied. The results were compared with those obtained from LiF:Mg,Cu,P usually used for the determination of absorbed dose in mammography. Measurements both per unit air kerma and In vivo were performed using a mammography unit model DMR (General Electric). The results showed that ZrO{sub 2} TLDs can be used for the same X-ray dosimetry applications as LiF:Mg,Cu,P, with each type having the disadvantage of a response dependent on energy, particularly at low energies. These results indicate a considerable potential for use in routine control and In vivo ES measurements in mammography. (Author)

    1996-11-01

    This study investigates the reasons for entry to medicine and the career perspectives of phase III medical students of the Universiti Sains Malaysia (USM). The majority of the students were Malays from low socio-economic backgrounds who entered medical school after completing a 2-year matriculation course. An interest in medicine and helping people were the two main stated reasons for entry to medical school. A group of students wishing to work in private practice was identified. In comparison to the rest of the study body, students in the group were: not well prepared to enter medical school; dissatisfied with the course; and subject to family influences. A desire for monetary gain motivated their choice of medicine as a career. Overall, 13% of the students wished to change career because they were dissatisfied with their experience of medicine as undergraduates. The study did not find a significant difference in career intentions between female and male medical students. However, women were less likely to seek entrance into private practice or pursue formal postgraduate education. The choice of surgery as a career was confined to men. About 90% of the students had already decided on their future specialty. Four well-established specialties were their most popular choices. The gender of the students had no significant influences of the decision to continue into postgraduate education. The proportion of female students who wished to marry doctors was significantly higher than for male students. PMID:9217903

  1. Application of personal computer to development of entrance management system for radiating facilities

    International Nuclear Information System (INIS)

    The report describes a system for managing the entrance and exit of personnel to radiating facilities. A personal computer is applied to its development. Major features of the system is outlined first. The computer is connected to the gate and two magnetic card readers provided at the gate. The gate, which is installed at the entrance to a room under control, opens only for those who have a valid card. The entrance-exit management program developed is described next. The following three files are used: ID master file (random file of the magnetic card number, name, qualification, etc., of each card carrier), entrance-exit management file (random file of time of entrance/exit, etc., updated everyday), and entrance-exit record file (sequential file of card number, name, date, etc.), which are stored on floppy disks. A display is provided to show various lists including a list of workers currently in the room and a list of workers who left the room at earlier times of the day. This system is useful for entrance management of a relatively small facility. Though small in required cost, it requires only a few operators to perform effective personnel management. (N.K.)

    SubWavelength Structured Surfaces (SWS), by synthesizing effective index of refraction, offer an attractive way to mimic antireflective coating effects. It is of particular interest for some IR materials of high index of refraction such as CdTe or KRS-5. These material are often used for entrance window in cryogenic IR instrument in the 20 microns band. For these materials, multilayer antireflective coatings provide limited performances in transmission, while expected performances of SWS can be very high even for a wavelength range covering both the N and Q atmospheric windows, from 7 microns to 28 microns. The SWS simulates a gradient index layer. Its main parameters are its pitch and its depth. The pitches required depend on the IR material index. For CdTe and KRS5, they are around 3 microns to work in N-band and Q-band and around 6 microns to work only on Q- band, and the depth required is around 10 microns to work till 28 microns. We have tried a new approach to realize these structures by using excimer laser ablation technique. We describe the used technique and our results for different materials such as CdTe, KRS5, CsBr and CsI. Antireflection structured surfaces on CdTe could offer an increase in transmission better than 25 percent at 24 microns. We measured a transmission efficiency of near 96 percent between 23 micrometers and 35 micrometers on KRS-5, and more than 95 percent between 18.5 micrometers and 35.5 micrometers on CsI.

  7. A numerical solution for the entrance region of non-newtonian flow in annuli

    2003-01-01

    Full Text Available Continuity and momentum equations applied to the entrance region of an axial, incompressible, isothermal, laminar and steady flow of a power-law fluid in a concentric annulus, were solved by a finite difference implicit method. The Newtonian case was solved used for validation of the method and then compared to reported results. For the non-Newtonian case a pseudoplastic power-law model was assumed and the equations were transformed to obtain a pseudo-Newtonian system which enabled its solution using the same technique as that used for the Newtonian case. Comparison of the results for entrance length and pressure drop with those available in the literature showed a qualitative similarity, but significant quantitative differences. This can be attributed to the differences in entrance geometries and the definition of asymptotic entrance length.

    Homodimeric proton-translocating pyrophosphatase (H(+)-PPase; EC 3.6.1.1) is indispensable for many organisms in maintaining organellar pH homeostasis. This unique proton pump couples the hydrolysis of PPi to proton translocation across the membrane. H(+)-PPase consists of 14-16 relatively hydrophobic transmembrane domains presumably for proton translocation and hydrophilic loops primarily embedding a catalytic site. Several highly conserved polar residues located at or near the entrance of the transport pathway in H(+)-PPase are essential for proton pumping activity. In this investigation single molecule FRET was employed to dissect the action at the pathway entrance in homodimeric Clostridium tetani H(+)-PPase upon ligand binding. The presence of the substrate analog, imidodiphosphate mediated two sites at the pathway entrance moving toward each other. Moreover, single molecule FRET analyses after the mutation at the first proton-carrying residue (Arg-169) demonstrated that conformational changes at the entrance are conceivably essential for the initial step of H(+)-PPase proton translocation. A working model is accordingly proposed to illustrate the squeeze at the entrance of the transport pathway in H(+)-PPase upon substrate binding. PMID:23720778

    The aim of this study was to establish an indirect method to calculate the values of entrance surface air kerma in patients undergoing diagnostic examinations in X-ray systems with computed radiography based on the exposure index. The entrance surface air kerma values were compared with values obtained also indirectly based on measurements of X-ray tube output. The mean±standard deviation (1σ) and third quartile for entrance surface air kerma calculated from the exposure index were 2.1±1.0 mGy and 3.0 mGy, respectively. For entrance surface air kerma based on measurements of the X-ray tube output, the mean±standard deviation (1σ) and third quartile were respectively 3.1±1.9 mGy and 5.5 mGy. The observed values of entrance surface air kerma are smaller than the reference level adopted in Brazil (10 mGy). The results obtained with both methods were similar when taking into account the estimated uncertainties in the determination of air kerma values, although the reproducibility of the determinations based on the exposure index is better.

  1. A novel beam focus control at the entrance to the ANU 14UD accelerator

    International Nuclear Information System (INIS)

    Tandem electrostatic accelerators often require the flexibility to operate at variety of terminal voltages to cater for various user needs. However beam transmission will only be optimal for a limited range of terminal voltages. This paper describes a focussing system that greatly expands the range of terminal voltages for optimal transmission. This is achieved by controlling the gradient of the entrance of the low-energy tube providing an additional controllable focusing element. Up to 150 kV is applied to the fifth electrode of the first unit of the accelerator tube giving control of the tube entrance lens strength. Beam tests to confirm the efficacy of the lens have been performed. These tests demonstrate that the entrance lens control eliminates the need to short out sections of the tube for low terminal voltage operation. (authors)

  4. Entrance channel dependence of back angle yields: orbiting in 24Mg+16O reaction

    International Nuclear Information System (INIS)

    The back-angle yields of the oxygen and carbon particles from the 24Mg+16O reaction have been measured at E/sub Lab/(24Mg) = 79.5 MeV by using reverse kinematics. Comparison with data for the 28Si+12C reaction forming the same compound nucleus at the same excitation energy and with very similar spin distribution, demonstrates a strong entrance channel effect which is favoring the break-up into the entrance channel with large excitation energy. This result qualitatively supports the picture of the formation of a long-lived orbiting complex whose structure and decay are dependent on the entrance channel. The compound nucleus contribution has been inferred to be less than 15% of the measured oxygen cross-section. 9 references

The effect of entrance channel, deformations (up to β2), barrier modification and fusion enhancement are addressed. The decay pattern of compound system, formed in different channels at comparable energy around the barrier, shows change in magnitude with structure remains almost same. There is an increase in the fusion probability with decrease in barrier modification, which leads to fusion enhancement at low energies. The higher ℓ values are contributing for 132Sn + 40Ca channel at lower energies as compare to 124Sn + 48Ca. It is inferred that with the use of stable and radioactive beam, forming same compound nucleus, the entrance channel dependence changes with the excitation energy

    2016-01-01

    In the 17th and 18th centuries the entrance to the guild chamber of the Amsterdam Guild of Surgeons was located in the right corner-tower of the Waag on the Nieuwmarkt in Amsterdam. The surgeons entered their guild chamber through this door for guild meetings or to take surgical exams. The entrance also gave access to the anatomy theatre, the 'Theatrum Anatomicum', where anatomical dissections - anatomy lessons - took place. There was a bust of Hippocrates in the facade above the door, and the inscription 'Theatrum Anatomicum'. The series of 'anatomy lessons' reminds us of the famous paintings that were commissioned by the Surgeons' Guild. At the beginning of the 17th century, a skeleton was painted on the door in the gateway, and this marked the entrance to the Surgeons' Guild for almost 200 years. We examined, from a historical perspective, how the gateway to the guild chamber of the Amsterdam Guild of Surgeons was transformed over time. PMID:27122076

    In this study, a computer code is developed to numerically investigate a magnetic bead micromixer under different conditions. The micromixer consists of a microchannel and numerous micro magnetic particles which enter the micromixer by fluid flows and are actuated by an alternating magnetic field normal to the main flow. An important feature of micromixer which is not considered before by researchers is the particle entrance arrangement into the micromixer. This parameter could effectively affect the micromixer efficiency. There are two general micro magnetic particle entrance arrangements in magnetic bead micromixers: determined position entrance and random position entrance. In the case of determined position entrances, micro magnetic particles enter the micromixer at specific positions of entrance cross section. However, in a random position entrance, particles enter the microchannel with no order. In this study mixing efficiencies of identical magnetic bead micromixers which only differ in particle entrance arrangement are numerically investigated and compared. The results reported in this paper illustrate that the prepared computer code can be one of the most powerful and beneficial tools for the magnetic bead micromixer performance analysis. In addition, the results show that some features of the magnetic bead micromixer are strongly affected by the entrance arrangement of the particles.

  9. Why Do Some Estuaries Close: A Model of Estuary Entrance Morphodynamics.

    Intermittently Closed/Open Coastal Lakes/Lagoons (ICOLLs) are a form of wave-dominated, microtidal estuary that experience periodic closure in times of low river flow. ICOLL entrance morphodynamics are complex due to the interaction between wave, tidal and fluvial processes. Managers invest substantial funds to artificially open ICOLLs as they flood surrounding property and infrastructure, and have poor water quality. Existing studies examine broad scale processes but do not identify the main drivers of entrance condition. In this research, the changes in entrance geomorphology were surveyed before and after artificial entrance openings in three ICOLLs in Victoria, Australia. Changes in morphology were related to continuous measures of sediment volume, water level, tide and wave energy. A six-stage quantitative phase model of entrance geomorphology and hydrodynamics is presented to illustrate the spatio-temporal variability in ICOLL entrance morphodynamics. Phases include: breakout; channel expansion with rapid outflow; open with tidal exchange; initial berm rebuilding with tidal attenuation; partial berm recovery with rising water levels; closed with perched water levels. Entrance breakout initiates incision of a pilot channel to the ocean, whereby basin water levels then decline and channel expansion as the headcut migrates landwards. Peak outflow velocities of 5 m/s-3 were recorded and channel dimensions increased over 6 hrs to 3.5 m deep and 140 m wide. When tidal, a clear semi-diurnal signal is superimposed upon an otherwise stable water level. Deep-water wave energy was transferred 1.8 km upstream of the rivermouth with bores present in the basin. Berm rebuilding occurred by littoral drift and cross-shore transport once outflow ceased and microscale bedform features, particularly antidunes, contributed to sediment progradation. Phase duration is dependant on how high the estuary was perched above mean sea level, tidal prism extent, and onshore sediment supply

    The heat transfer argumentation in the thermal entrance region of a narrow rectangular channel roughened with repeated ribs was investigated experimentally for removing high-density heat generated in a solid target. This solid target works as a spallation neutron source coupled with a proton beam accelerator of 1.5 MW power. Experimental results showed that the thermal entrance region could extent to the range of 50-60 times as long as the equivalent diameter from the coolant inlet, and that the heat transfer coefficient in the region could be estimated with the Gnielinski`s correlation.

    Full Text Available In breast radiotherapy, skin flashing of treatment fields is important to account for intrafraction movements and setup errors. This study compares the two different intensity extension methods, namely, Virtual Bolus method and skin flash tool method, to provide skin flashing in intensity modulated treatment fields. The impact of these two different intensity extension methods on skin dose was studied by measuring the entrance dose of the treatment fields using semiconductor diode detectors. We found no significant difference in entrance dose due to different methods used for intensity extension. However, in the skin flash tool method, selection of appropriate parameters is important to get optimum fluence extension.

    The population intensity of some SD bands in the mass 150 region were observed to depend on the mass symmetry of the entrance channel in the fusion reaction. The authors raised the possibility that the population of SD bands had a memory of the entrance channel. To check this interesting possibility, we made measurements of the population intensities of superdeformed (SD) bands in the {sup 160}Gd({sup 36}S,5n){sup 191}Hg and {sup 130}Te({sup 64}Ni,3n){sup 191}Hg reactions. To ensure that any observed effect was not due to a simple angular momentum difference in the entrance channels, we also measured the average entry points and spin distributions of normal and SD states in {sup 191}Hg in the two reactions. The entry points and spin distributions for {sup 191}Hg are the same and, indeed, so are the SD intensities in the two reactions. Hence, no entrance-channel effect is observed in the population of the SD band in {sup 191}Hg, in contrast with data for SD bands in the mass 150 regions. We suggest that the effect observed previously in the mass 150 region is due to an angular momentum effect. A letter reporting our results was submitted for publication.

    The entrance of newly qualified medical specialists into daily practice is considered to be a stressful period in which curriculum support is absent. Although engaging in both personal and professional learning and development activities is recognized fundamental for lifelong professional competence, research on medical professionals' entrance into practice is scarce. This research aims to contribute to the framework of medical professionals' informal learning and outlines the results of an exploratory study on the nature of learning in daily practice beyond postgraduate training. Eleven newly qualified physicians from different specialized backgrounds participated in a phenomenographic study, using a critical incident method and a grounded theory approach. Results demonstrated that learning in the workplace is, to a large extent, informal and associated with a variety of learning experiences. Analysis shows that experiences related to diagnostics and treatments are important sources for learning. Furthermore, incidents related to communication, changing roles, policy and organization offer learning opportunities, and therefore categorized as learning experiences. A broad range of learning activities are identified in dealing with these learning experiences. More specifically, actively engaging in actions and interactions, especially with colleagues of the same specialty, are the most mentioned. Observing others, consulting written sources, and recognizing uncertainties, are also referred to as learning activities. In the study, interaction, solely or combined with other learning activities, are deemed as very important by specialists in the initial entrance into practice. These insights can be used to develop workplace structures to support the entrance into practice following postgraduate training. PMID:26395113

    This study was aimed to compare skin entrance dose of digital radiography with that of film radiography and to show the dose reduction achievement with digital systems at 11 dental schools in Korea. Forty six intraoral radiographic systems in 11 dental schools were included in this study. Digital sensors were used in 33 systems and film was used in 13 systems. Researchers and the volunteer visited 11 dental schools in Korea. Researchers asked the radiologic technician at each school to set the exposure parameters and aiming the x-ray tube for the peri apical view of the mandibular molar of the volunteer. The skin entrance doses were measured at the same exposure parameters and distance by the technician for each system with a dosimeter (Multi-O-Meter; Unifors instruments, Billdal, Sweden). The median dose was 491.2 μGy for digital radiography and 1,205.0 μGy for film radiography. The skin entrance dose in digital radiography was significantly lower than that of film radiography (p<0.05). Fifty-nine percent skin entrance dose reduction with digital peri apical radiography was achieved over the film radiography in Korean dental schools.

    2012-03-01

    This work is the development of a MOSFET based surface in vivo dosimetry system for total body irradiation patients treated with bilateral extended SSD beams using PMMA missing tissue compensators adjacent to the patient. An empirical formula to calculate midplane dose from MOSFET measured entrance and exit doses has been derived. The dependency of surface dose on the air-gap between the spoiler and the surface was investigated by suspending a spoiler above a water phantom, and taking percentage depth dose measurements (PDD). Exit and entrances doses were measured with MOSFETs in conjunction with midplane doses measured with an ion chamber. The entrance and exit doses were combined using an exponential attenuation formula to give an estimate of midplane dose and were compared to the midplane ion chamber measurement for a range of phantom thicknesses. Having a maximum PDD at the surface simplifies the prediction of midplane dose, which is achieved by ensuring that the air gap between the compensator and the surface is less than 10 cm. The comparison of estimated midplane dose and measured midplane dose showed no dependence on phantom thickness and an average correction factor of 0.88 was found. If the missing tissue compensators are kept within 10 cm of the patient then MOSFET measurements of entrance and exit dose can predict the midplane dose for the patient. PMID:22298238

    Full Text Available Recycling irrigation reservoirs (RIRs are an emerging aquatic ecosystem of critical importance, for conserving and protecting increasingly scarce water resources. Here, we compare water quality between runoff entrance and middle of four RIRs in nurseries in Virginia (VA and Maryland (MD. Surface water temperature (T and oxidation-reduction potential (ORP were lower in the middle than at the entrance, while the trend was opposite for dissolved oxygen (DO, pH and chlorophyll a (Chla. The magnitude of these differences between the entrance and middle decreased with increasing depth. These differences were magnified by water stratification from April to October. Minimum differences were observed for electrical conductivity (EC, total dissolved solids (TDS and turbidity (TUR. Cluster analyses were performed on water quality difference data to evaluate whether the differences vary with respect to reservoirs. Two clusters were formed with one consisting primarily of VA reservoirs, and the other consisting mostly of MD reservoirs in both years. Water quality in the middle and at the entrance of RIRs was expected to vary greatly because of runoff inflow. The two-point water quality differences observed here, although statistically significant, are not large enough to cause significant impact on crop health and productivity for most water quality parameters except pH. Additional analysis of outlet data shows that the range and magnitude of water quality difference between the middle and the outlet are comparable to those between the middle and entrance of RIRs. These results indicate that monitoring at a single point is sufficient to obtain reliable water quality estimates for most water quality parameters in RIRs except pH. This is important when considering the cost of labor and equipment necessary for documenting water quality in agricultural production systems. However, additional pH measurements are still necessary to make practical water quality

    The hohlraum is very crucial for indirect laser driven Inertial Confinement Fusion. Usually, its shape is designed as sphere, cylinder, or rugby with some kind of fixed functions, such as ellipse or parabola. Recently, a spherical hohlraum with octahedral 6 laser entrance holes (LEHs) has been presented with high flux symmetry [Lan et al., Phys. Plasmas 21, 010704 (2014); 21, 052704 (2014)]. However, there is only one shape parameter, i.e., the hohlraum to capsule radius ratio, being optimized. In this paper, we build the hohlraum with octahedral 6LEHs with a unified free-form representation, in which, by varying additional shape parameters: (1) available hohlraum shapes can be uniformly and accurately represented, (2) it can be used to understand why the spherical hohlraum has higher flux symmetry, (3) it allows us to obtain a feasible shape design field satisfying flux symmetry constraints, and (4) a synthetically optimized hohlraum can be obtained with a tradeoff of flux symmetry and other hohlraum performance. Finally, the hohlraum with octahedral 6LEHs is modeled, analyzed, and then optimized based on the unified free-form representation. The results show that a feasible shape design field with flux asymmetry no more than 1% can be obtained, and over the feasible design field, the spherical hohlraum is validated to have the highest flux symmetry, and a synthetically optimal hohlraum can be found with closing flux symmetry but larger volume between laser spots and centrally located capsule.

In this paper, we build the hohlraum with octahedral 6LEHs with a unified free-form representation, in which, by varying additional shape parameters: (1) available hohlraum shapes can be uniformly and accurately represented, (2) it can be used to understand why the spherical hohlraum has higher flux symmetry, (3) it allows us to obtain a feasible shape design field satisfying flux symmetry constraints, and (4) a synthetically optimized hohlraum can be obtained with a tradeoff of flux symmetry and other hohlraum performance. Finally, the hohlraum with octahedral 6LEHs is modeled, analyzed, and then optimized based on the unified free-form representation. The results show that a feasible shape design field with flux asymmetry no more than 1% can be obtained, and over the feasible design field, the spherical hohlraum is validated to have the highest flux symmetry, and a synthetically optimal hohlraum can be found with closing flux symmetry but larger volume between laser spots and centrally located capsule.

  14. Reactor building

    International Nuclear Information System (INIS)

    The whole reactor building is accommodated in a shaft and is sealed level with the earth's surface by a building ceiling, which provides protection against penetration due to external effects. The building ceiling is supported on walls of the reactor building, which line the shaft and transfer the vertical components of forces to the foundations. The thickness of the walls is designed to withstand horizontal pressure waves in the floor. The building ceiling has an opening above the reactor, which must be closed by cover plates. Operating equipment for the reactor can be situated above the building ceiling. (orig./HP)

  15. Pediatric radiography entrance doses for some routine procedures in three hospitals within eastern Nigeria

    Directory of Open Access Journals (Sweden)

    Egbe N

    2008-01-01

    Full Text Available A survey of the entrance surface doses in the routine radiography of children in eastern Nigeria has been carried out in three hospitals, using thermoluminescence detectors. Chest, abdomen, lumbar spine, skull and pelvis were covered in this study. Findings reveal that doses are higher than the recommended reference values elsewhere, as well as values reported for Sudan. The mean percentage difference in entrance doses for chest radiography for this study and an earlier one carried out for three hospitals in the west of Nigeria is about 44.7%. The high doses are traceable to a lack of standardization in procedure, resulting in use of low tube voltages and high currents for examination, as well as the status of facilities in the area. Recommendations are made for immediate corrective measures to lower the doses.

  16. Entrance channel dependence of fission fragment anisotropies - a direct experimental signature of fission before equilibration

    International Nuclear Information System (INIS)

    In several cases of heavy ion induced fusion-fission reactions, the fission fragment angular distributions exhibit much larger anisotropies than predicted by the standard Halpern-Strutinsky theory. Several explanations have been put forward to interpret these anomalous angular distributions. One of them is that a characteristic signature of fission before full K-equilibration will be an entrance channel dependence of the fragment anisotropies for target-projectile combinations across the Businaro-Gallone ridge in the mass/charge asymmetry degree of freedom. To look for any such entrance channel dependence of fragment anisotropies, we have carried out measurements of fragment angular distributions in fission induced by boron, carbon, oxygen ions on thorium and neptunium targets and by fluorine ions on neptunium target at above barrier energies.

    MA Jian-feng; SHEN Xin-rong; ZHANG Ming-kan; ZHANG Ben-Zhao

    2006-01-01

    Three-dimensional laminar flow in the entrance region of rotating curved pipes was investigated. The governing equations were written in an orthogonal curvilinear coordinate system and solved with a fully three-dimensional numerical method. The development of secondary flow, axial velocity, local and average friction factors for different cases of rotation were given and discussed in detail. The results show that rotation influences the flow structure and friction factor greatly and that the secondary flow is sink-type in the early stage of development and then turns to vortex structure. The average friction factor and the intensity of secondary flow have drastic decrease near the entrance. At some proper rotation, the average friction factor can be noticeably reduced.

  18. Entrance and exit region friction factor models for annular seal analysis. Ph.D. Thesis

    Elrod, David Alan

    1988-01-01

    The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal experimentally. Two friction factor models are developed for annular seal analysis; one model is based on flat-plate flow theory; the other uses empirical entrance and exit region friction factors. The friction factor predictions of the models are compared to experimental results. Each friction model is used in an annular gas seal analysis. The seal characteristics predicted by the two seal analyses are compared to experimental results and to the predictions of Nelson's analysis. The comparisons are for smooth-rotor seals with smooth and honeycomb stators. The comparisons show that the analysis which uses empirical entrance and exit region shear stress models predicts the static and stability characteristics of annular gas seals better than the other analyses. The analyses predict direct stiffness poorly.

  4. Entrance surface dose measurement on the thyroid gland in orthopantomography: The need for optimization

    International Nuclear Information System (INIS)

    Background: The anatomic position and proven radiosensitivity of the thyroid make it an organ of concern in dental x-ray examinations. A National Radiation Protection Department sponsored pilot study carried out in the Dental Radiology Department of Rafsanjan University of Medical Sciences, to assess if the radiation dose in panoramic radiographies could be reduced without significant impairment of the subjective image quality. Materials and methods: Thermoluminescent dosimetry is widely acknowledged to be the recommended method for measuring entrance surface doses. In this study, entrance surface doses was measured using LiF thermoluminescent dosimeters (TLD-100) on the thyroid of 40 patients who had referred to the School of Dentistry, Rafsanjan University of Medical Sciences. Patients were no exposed to any additional radiation and the radiographs were used for diagnostic purposes. Thermoluminescent dosimetry were calibrated with radiation energies similar to those commonly used in orthopantomography. Results: The overall mean entrance surface doses on the thyroid in orthopantomography was 0.071±0.012 mGy (ranged from 0.01 to 0.40 mGy). The mean entrance surface doses for radiographies performed with 66 k Vp (20 patients) and 68 k Vp (20 patients) were 0.072± 0.016 respectively. No statistically significant difference was found between these means. Conclusions: The measured surface doses in our study are inconsistent with the only one already reported about the same experiment. However, due to lack of national diagnostic reference levels for orthopantomography, it is not clear whether in case of the Pm 2002 Cc unit used in this experiment, reducing the radiation dose to a level that still keeps a diagnostically acceptable image quality is necessary

  11. Comparison of entrance surface doses of some X ray examinations with CEC reference doses

    International Nuclear Information System (INIS)

    Entrance surface dose (ESD) measurements have been carried out in Nigeria as part of the ongoing dose reduction programme. Thermoluminescence dosemeters (TLD) were used to measure skin entrance doses for four common radiographic views in three hospitals. The mean ESD for the PA chest examination in all the participating hospitals was in the range 0.12-4.46 mGy. The mean ESD for the AP skull, PA skull and LAT skull were 8.55, 5.17 and 6.97 mGy respectively. The mean ESD values are greater than the CEC reference doses, except for rooms 1 and 2 in UCH where the entrance surface doses for PA chest examination are below the CEC reference dose. The QA test results show non-compliance of the accuracy of the tube voltage with acceptance limit in three rooms. The timer accuracy is also not within the acceptance limit in two rooms. The reproducibility of both the kVp and timer in all the rooms is good. (author)

    2005-01-01

    With the development of wideband IP network, many new IP-Based multimedia applications appear ceaselessly. The real-time multimedia application requires that the IP network provides QoS. To the end-to-end real-time multimedia communication, the QoS service includes the trunk QoS and the entrance QoS. The trunk QoS has some feasible technologies, such as RSVP and DiffServ. But, the entrance QoS has few technologies at the moment. So, this paper introduces the entrance bandwidth control to get the end-to-end QoS. The design and scheme of bandwidth controller applying to the usual Internet application and real-time media communication is provided in this paper. It distinguishes between the usual Internet applications, such as HTTP and FTP, and the real-time multimedia applications, such as Internet telephony and videoconferencing. Then they will be dealt with in different ways in order to satisfy the QoS requirements of different types of services. In this paper, we propose a new bandwidth control method for real-time multimedia communication. The principle, the implementing flow, the control policy and the application scheme are discussed.

  13. Passively scattered proton beam entrance dosimetry with a plastic scintillation detector

    International Nuclear Information System (INIS)

    We tested the feasibility of using plastic scintillation detectors (PSDs) for proton entrance dosimetry. A PSD built with BCF-12 scintillating fiber was used to measure the absolute entrance dose of a passively scattered proton beam for energies ranging from 140 to 250 MeV, and for a range of spread out Bragg peak (SOBP) widths at two energies, to quantify the effect of ionization quenching on the response of the detector and to determine the necessity of Cerenkov radiation correction in proton beams. The overall accuracy and precision of the PSD was evaluated by measuring lateral beam profiles and comparing the results with profiles measured using film. The PSD under-responded owing to ionization quenching, exhibiting approximately a 7% loss of signal at the highest energy studied (250 MeV) and a 10% loss of signal at the lowest energy studied (140 MeV). For a given nominal energy, varying the SOBP width did not significantly alter the response of the PSD. Cerenkov radiation contributed negligibly to the PSD signal and can be safely ignored without introducing more than 1% error in the measured dose. Profiles measured with the PSD and film agreed to within the uncertainty of the detector, demonstrating good relative accuracy. Although correction factors were necessary to account for ionization quenching, the magnitude of the correction varied minimally over a broad range of energies; PSDs therefore represent a practical detector for proton entrance dosimetry.

    Full Text Available We consider the flow at the inlet to the suction square hole with sharp edges, which is located in an infinite space. The purpose of this study is to construct a mathematical model of flow separation at the entrance to square suction canal with sharp edges, located in infinite space, by using square vortex frameworks. As a part of ideology of the method of discrete vortices in the non-stationary quasi-axisymmetric formulation, we constructed the mathematical model of separated flow at the inlet to the square aspirating pipe and its software-algorithmic implementation. We have determined the velocity field at the entrance to suction channel and a line of flow separation. Determine the velocity field in typical cross-sections of the suction channel, dimensions of the efficient absorption, compression ratio of the jet. Were received analytical formulas for calculating separation surfaces current. Profiling the entrance opening of the suction hole detected on the outlines separation surface will improve the acoustic and aerodynamic properties of the exhaust systems. The obtained results can be useful for designing of local exhaust ventilation of reduced energy consumption.

  15. Magnetic suppression gridded lens system at the entrance of a tandem accelerator

    International Nuclear Information System (INIS)

    A gridded lens, affixed to the first insulated electrode at the entrance to the accelerator tube of our Model FN Tandem, was first installed about 2-1/2 years ago. It was an apparent instant success; the transmission of the Tandem for heavy ions from a sputter source was increased from about 30% to about 60%, and the dependence of low energy focussing parameters on terminal potential was substantially reduced. These benefits are to be expected because the effective lens at the entrance to the tube is weakened. The increase in size of the entrance pupil also manifests itself as a reduced sensitivity to low energy beam steering. However, after some months of operation, Tom Trainor showed that fluctuations in the beam (on a time scale of 1 to 4 seconds) were caused by the grid. Months later, it was noted that the accelerated beam was displaced sideways (approx. 1 to 2 cm) as it emerged from the high energy tube. About one year ago, the grid produced, severe electrical breakdown in the first (straight) section of the accelerating tube. The maximum useful terminal potential was limited to approx. 6.5 MV. A fourth ailment was induced by grid operation. Even with moderate-sized beams an unusual amount of x-radiation was produced on a monitor placed outside the tank midway between the terminal and the low-energy end. In this paper we describe the technique used to reduce these effects

    Physical model of cone-cylinder nozzle was established. Based on the CFD software of FLUENT, the flow field about abrasive water jet in cone-cylinder nozzle was simulated by use of standard k-ɛ turbulent model, Lagrange Discrete Phase Model and SIMPLE algorithm. The simulation results show that axial velocity of abrasive particle is always smaller than axial velocity of abrasive particle and increases gradually with the increase of axial distance. Axial static pressure of water decreases gradually with the increase of axial distance. Axial velocity of abrasive particle at the exit of cone-cylinder nozzle decreases with the increase of nozzle entrance diameter. And axial static pressure of water at the entrance of cone-cylinder nozzle decreases with the increase of nozzle entrance diameter. 8mm is selected as an optimal nozzle entrance diameter.

  4. Study of mass asymmetry effect in the entrance channel for deep inelastic collisions between heavy ions

    International Nuclear Information System (INIS)

    The reactions (52Cr+56Fe) and (16O+92Mo) were studied extensively to learn about the influence of the mass asymmetry of the entrance channel on Deep Inelastic Collisions (DIC). These two systems have very different entrance channel asymmetry but both of them lead to the same ensemble of nucleons. The incident energies were choosen to be 265 MeV for Cr and 187 MeV for O so that the maximum angular momentum is the same in both the cases. The experimental results of the quasi-symmetric system (Cr+Fe) show that a large number of fragments have the characteristic properties of fission fragments. However, comparison of these results with those of an asymmetric system (O+Mo), forming the same compound nucleus with higher excitation energy, leads to think that these events can not be accounted for fission. It has been shown that these events could be considered as DIC products. The distributions of different multidifferential observables were reproduced with the help of a diffusion model, and with the condition of introducing a notion of half life time of the composite system. The half-life, thus calculated, seems to vary as a function of mass asymmetry of the entrance channel: 20.10-22S for the system Cr+Fe, 2.10-22S for the system O+Mo and 10.10-22S for a third system 20Ca+64Ni which has an intermediate mass asymmetry. Further it seems that the evaporation residue cross section in symmetric systems is far less than what we can expect from classical calculations

For this type of fractures, it is expected that this does not basically affect the Heat Transport Primary Loop behaviour since the main heat drain is the fracture. (Author)

    We investigate the entrance channel dynamics for the reactions $\\mathrm{^{70}Zn}+\\mathrm{^{208}Pb}$ and $\\mathrm{^{48}Ca}+\\mathrm{^{238}U}$ using the fully microscopic time-dependent Hartree-Fock (TDHF) theory coupled with a density constraint. We calculate excitation energies and capture cross-sections relevant for the study of superheavy formations. We discuss the deformation dependence of the ion-ion potential for the $\\mathrm{^{48}Ca}+\\mathrm{^{238}U}$ system and perform an alignment angle averaging for the calculation of the capture cross-section. The results show that this parameter-free approach can generate results in good agreement with experiment and other theories.

  7. Entrance-channel coherence in dissipative heavy-ion collisions and compound-nucleus formation

    International Nuclear Information System (INIS)

    The fast approach of two nuclei in a heavy-ion collision leads to a configuration which is diabatically related to the ground states of the separated nuclei and hence, is strongly coherent with respect to the entrance channel. This first stage of the process is followed by the decay of this doorway-like configuration (second stage). The following (third) stage is described by standard statistical theory with local equilibrium. A phenomenological model of this process is formulated and first results are presented. In addition to compound-nucleus formation and the conventional fast component a long-living component of dissipative collisions is obtained. (orig.)

  10. Study of enhanced entrance pressure losses in a rod bundle experiment employing heavy liquid metal coolant

    International Nuclear Information System (INIS)

    Innovative nuclear reactor concepts like accelerator driven systems (ADS) or the lead cooled fast reactor LFR employ lead bismuth eutectic (LBE) as a coolant. Within the framework of the EU project THINS (thermalhydraulics of innovative nuclear systems) a rod bundle experiment in LBE is performed employing characteristic dimensions at the Karlsruhe Liquid Metal Laboratory (KALLA)l of Karlsruhe Institute of Technology (KIT). In a first measurement campaign it is observed that the pressure drop across the first spacer in the rod bundle experiment is noticeable larger than at the subsequent spacers. We speculate that this is due to blockage of the very narrow spacer channels and numerically investigate whether there are substantially enhanced entrance effects. The present numerical study investigates the whole rod bundle including the entrance region in order to show possible mechanisms which can increase the pressure drop of the first spacer even if no blockage is present. The extra pressure loss compared to simulations with uniform inflow is found to be very small which supports the speculation of blockage. Since rod bundle flow is known to depend very sensitive on turbulence models and mesh resolution we carefully verify that our simulations use an adequate computation domain, mesh resolution and turbulence model.

  11. Numerical analysis of convective heat transfer in the entrance region of cusped ducts

    International Nuclear Information System (INIS)

    This paper presents the numerical solution of convective heat transfer in the thermal entrance region of cusped ducts. These ducts are formed contiguously by assembling three, four, or five cylindrical rods having the same diameter next to each other. The ducts are also subjected to a constant wall temperature. The solution to the discretization of these duct geometries is obtained by using the numerically generated boundary fitted coordinate system. According to this method, the complex domain in the physical plane is transformed into a regular square domain in the computational plane. The finite difference method based on the control volume is then used to discretize the transformed governing equation. To prove the validity of the results, the present method is also used to obtain the convective heat transfer solution in the entrance region of square and equilateral triangular ducts. Comparison of the results for square and equilateral triangular ducts with available data published in the open literature gives excellent agreement. The representative curves illustrating variations of the bulk temperature and Nusselt numbers with pertinent parameters are plotted for the three different duct geometries

  12. Statistic analysis of death risk of A-bomb victim due to entrance in Hiroshima city

    International Nuclear Information System (INIS)

    The purpose of this study was to elucidate the health effect of indirect exposure to A-bomb by estimation of mortality risk of the cohort entering the City along the passed days after explosion (Aug. 6, 1945) with consideration about sex and age at the exposure. Subjects were 47,144 survivors (27,062 males) at Jan. 1, 1970, who had been registered as the city entrance victim in ABS (Database of A-bomb Survivors in Hiroshima Prefecture), and followed-up until Dec. 31, 2010. Estimated was the risk of death due to malignant neoplasm except leukemia at their age t during the follow-up using t as the variable and based on multistage carcinogenetic hypothesis: parameters were estimated with Cox likelihood method optimized by comparison of logarithmic likelihood. It was recorded that 80% of males and 73% females entered the city before Aug. 8, and their average ages at entrance were 33.8 and 28.8 y, respectively. Until the follow-up end, 16% of males and 9% females died from the malignancy. When the radiation dose was assumed infinitively close to the natural dose later than Aug. 11, death risk of those who had entered the city before Aug. 8 was found significantly higher than those after that day. The excessive relative mortality risk from the malignancy at age 75 y was found to be 13% in males and 8% in females assuming that they had entered the city at age 20 y. (T.T.)

  13. Aortic dissection with the entrance tear in transverse aorta: analysis of 12 autopsy patients.

    Roberts, C S; Roberts, W C

    1990-11-01

    Clinical and autopsy findings are described in 12 patients who had fatal aortic dissection with the entrance tear in the transverse aorta. The 12 patients represent 7% of 182 autopsies of spontaneous aortic dissection studied by us. The ages of the 12 patients at death ranged from 37 to 87 years (mean, 67 years). Eight were men; 8 had a history of systemic hypertension, and 10 had hearts of increased weight. Diagnosis of aortic dissection was made during life in only 4 of the 12 patients. All 12 patients died of rupture of the false channel within 2 weeks of onset of signs or symptoms compatible with dissection. The direction of aortic dissection from the entrance tear was entirely retrograde in 4 patients, entirely anterograde in 4 patients, and in both directions in 4 patients. Hemopericardium occurred in the first group, left hemothorax in the second group, and either in the last group. Of the 8 patients in whom the ascending aorta was involved, the retrograde dissection in each extended to the aortic root, 6 had pulmonary adventitial hemorrhage, and 4 had involvement of the arch arteries by dissection. In the 4 patients with strictly anterograde dissection, none had dissection in the arch arteries. Thus, tear in the transverse aorta causes a dissection that is usually fata, that often dissects retrogradely, and that may mimic dissection from a tear in ascending aorta. Aortic dissection from a tear in transverse aorta requires early operative intervention. PMID:2241339

    2010-04-15

    Objective: this study was aimed at evaluating the influence of the energy dependence of thermoluminescent materials on the determination of entrance skin dose in patients submitted to conventional radiographic studies (general radiology, mammography and dental radiology). Materials and methods: three different thermoluminescent materials were utilized: LiF:Mg,Ti, LiF:Mg,Cu,P and CaSO{sub 4}:Dy. These materials were exposed to standardized sources of X and gamma radiation and clinical X-ray beams. Results: calibration and energy dependence curves were obtained. All the materials showed a linear response as a function of the air kerma. As far as energy dependence is concerned, the CaSO{sub 4}:Dy and LiF:Mg,Ti samples showed the greatest variation on thermoluminescent responses as a function of the effective radiation beam. Conclusion: the tested materials showed an appropriate performance for detecting X radiation on standard and clinical X-ray beams. Although CaSO{sub 4}:Dy and LiF:Mg,Ti samples present a significant energy dependence in the considered energy range, these materials can be utilized for measuring entrance skin doses, provided appropriate correction factors are applied (author)

  15. Evaluation of radiological protection and dose of skin entrance in paediatric dentistry examinations

    International Nuclear Information System (INIS)

    In this work the radiological protection conditions and dose at the entrance of pediatric patients undergoing dental intraoral radiographs were evaluated. The study was conducted in two clinics of the dentistry course at the Federal University of Pernambuco, Recife, PB, Brazil, equipped with conventional X-ray apparatus, with 60 and 70 kV. 254 exams of 113 patients between the ages of 3 to 12 years were evaluated. The skin entrance dose was estimated using TLD-100 thermoluminescent dosemeters. During the examination were also recorded information regarding the time of exposure, radiographic technique used, use of thyroid protectors and lead apron, angle and distance of the cone Locator to the patient's skin. The results showed that the input skin doses ranged from 0.3 mGy to 10mGy. The lead apron was used in 71% of exams while the thyroid shield was only used in 58% of the exams. The exposure times ranged from 0,5s to 1,5s. From the results it can be concluded that the radiological procedures are not optimized and that in some cases the patient dose is high.

  16. Thermoluminescence measurements of entrance surface skin dose in exams of dog's chest in veterinary radiology

    International Nuclear Information System (INIS)

    This study aims to determine the entrance surface skin doses in dogs (with suspected pulmonary metastasis) submitted to chest X-rays using the technique of thermoluminescence (TL) dosimetry. Twenty seven radiologic exams of dogs of different breed and sizes were performed. The radiation doses were assessed using thermoluminescent dosimeters of calcium sulphate doped with dysprosium (CaSO4:Dy) produced at Instituto de Pesquisas Energeticas e Nucleares (IPEN-CNEN). The entrance surface skin dose range evaluated in this type of procedure was between 0.43 mGy to small size dogs and 4.22 mGy to big size dogs with repeated exams. The obtained results indicate that is extremely important the assessment of radiation doses involved in veterinary diagnostic radiology procedures, to evaluate the delivered doses to the animals, to be used as a parameter in the individual monitoring of pet's owners, who assist the animal positioning, and to protect occupationally exposed workers at the Veterinary Radiology Clinics.

  17. Development of mathematical model for estimation of entrance surface dose in mammography

    International Nuclear Information System (INIS)

    Computer simulation is a convenient and frequently used tool in the study of x-ray mammography, for the design of novel detector systems, the evaluation of dose deposition, x-ray technique optimization, and other applications. An important component in the simulation process is the accurate computer generation of x-ray spectra. A computer model for the generation of x-ray spectra in the mammographic energy rang from 18 keV to 40 ke V has been developed by Boone et al. Due to the lack of QC and dose measurement tools, in addition to unavailability of medical physics, a mathematical tool was developed for estimation of patient exposure and entrance dose. The proposed model require no assumptions concerning the physics of x-ray production in an x-ray tube, but rather makes use of x-ray spectra recently measured experimentally by John M Boone (Department of Radiology, University of California). Using experimental dose measurements for specific tube voltage and tube current the generated x-ray spectra were calibrated. The spectrum calibration factors show a tube voltage dependency. From the calibrated x-ray spectrum, the exposure and entrance dose were estimated for different k Vp and m A. Results show good agreement between the measured and estimated values for tube voltage between 18 to 45 k Vp with a good correlation of nearly 1 and equal slope. The maximum estimated different between the measured and the simulated dose is approximately equal to 0.07%.(Author)

    The aims of this work were to measure the entrance and exit dose for patient treated for head and neck tumors. The target absorbed dose was determined from the exit and entrance dose measurement. Twenty patients were evaluated. The results were compared to the calculated values and the midline dose was determinate and compared with the prescribed dose. 80 entrance doses and 80 exit doses measurements were performed. The average difference from expected values was 1.93% for entrance dose (SD 1.92%) and -0.34% for exit dose (SD 4.1%). The target absorbed dose differed from prescribed dose values by 2.94% (1.97%) for the results using the Noel method and 3.34% (SD: 2.29%) with the Rizzotti method. The total uncertainty budget in the measurement of the absorbed entrance and exit dose with diode, including diode reading, correction factors and diode calibration coefficient, is determined as 3.02% (1 s). Simple in vivo dose measurements are an additional safeguard against major setup errors and calculation or transcription errors that were missed during pre-treatment chart check. (authors)

  20. Reactor building

    International Nuclear Information System (INIS)

    The present invention concerns a structure of ABWR-type reactor buildings, which can increase the capacity of a spent fuel storage area at a low cost and improved earthquake proofness. In the reactor building, the floor of a spent fuel pool is made flat, and a depth of the pool water satisfying requirement for shielding is ensured. In addition, a depth of pool water is also maintained for a equipment provisionally storing pool for storing spent fuels, and a capacity for a spent fuel storage area is increased by utilizing surplus space of the equipment provisionally storing pool. Since the flattened floor of the spent fuel pool is flushed with the floor of the equipment provisionally storing pool, transfer of horizontal loads applied to the building upon occurrence of earthquakes is made smooth, to improve earthquake proofness of the building.

  2. The ratios of effective dose to entrance skin dose to the air kerma for some medical sources

    International Nuclear Information System (INIS)

    Results are presented for the ratios of the effective dose to skin entrance dose and to air kerma for broad beams of radiation expected to be encountered by medical workers. These workers are monitored by the Personal Radiation Monitoring Service (PRMS) using thermoluminescent dosimeters worn at the front of the body to provide estimates of the entrance skin dose. Factors are given for converting estimates of entrance skin dose to effective dose as defined by the International Commission on Radiological Protection (ICRP 1991) for beams incident on the body by one of three modes-from the front of the subject, from the back of the subject or by rotation around the subject. Additional tables are also given to calculate effective dose for these beams from a measurement of air kerma free-in-air

  4. Effects of entrance configuration on pressure loss and heat transfer of transitional gas flow in a circular tube

    International Nuclear Information System (INIS)

    Pressure loss and heat transfer of a transitional gas flow are affected significantly by the entrance configuration. The friction factor and the heat transfer coefficient were measured using a circular tube with four different kinds of entrance configurations. The Reynolds number at the transition from laminar to intermittent flow was varied from about 1,940 to 9,120. The intermittency factor was measured for heated and unheated flows ; and the relation between the intermittency and the friction factor or heat transfer coefficient was examined. Several existing correlations were tested and found to correlate with the experimental results fairly well. (author)

    High buildings or architectural complex in urban areas remarkably distort the urban surface wind fields. As the air flow approaches,local strong wind may appear around the buildings. The strong wind makes the pedestrians on sidewalks, entrances and terrace very uncomfortable and causes the pedestrian level wind environment problem. In this studies, hot-wire wind measurement, wind scouring in wind tunnel and numerical computation were carried out to evaluate the wind environment of tall buildings in the prevailing flow conditions in Beijing areas. The results obtained by three techniques were compared and mutually verified. The conclusions drawn from three approaches agree with each other. Also the advantages and limitations of each method were analyzed. It is suggested that the combination of different techniques may produce better assessment of wind environment around high buildings.

    Our study sought to determine whether experimental disclosure could improve exam performance and psychological health in students taking a graduate school entrance exam. Students preparing for the GRE, MCAT, LSAT, or PCAT were randomly assigned to write expressively about their upcoming exam or to a neutral writing condition. Participants completed measures of depressive symptoms and test anxiety before and after writing, and exam scores were collected. The experimental disclosure group had significantly higher test scores and significantly lower pre-exam depressive symptoms than the neutral writing group. Although benefits for depressive symptoms were found in expressive writers regardless of exam type, the advantage of expressive writing for test performance was only observed in students taking the MCAT or LSAT.

  8. Clinical implementation of entrance in vivo dosimetry with a diode system in MV photon beam radiotherapy

    International Nuclear Information System (INIS)

    In order to improve the quality assurance of radiation treatments, a diode system for in vivo entrance dose verification is being implemented in our department. Before clinical use of the diode system Nuclear Associates Model 30-472-8000, the acceptance tests and the measurement of the calibration and correction factors were carried out. For conventional treatment setup, diode lecture only requires correction for variation in: source to surface distance -SSD- (CFSSD), temperature (CFT), calibration factor due to accumulated dose (CFcai) and the accelerator output (CFout). Therefore, the expected diode reading Rexp can be obtained from the planned SSD and dose DTPS at dmax (both given by the treatment planning system -TPS- Eclipse v7.3.10) through the relation Rexp = DTPS / (CFcai x CFout x CFSSD x CFT)

  9. Entrance windows in germanium low-energy x-ray detectors

    International Nuclear Information System (INIS)

    It was found experimentally that high-purity Ge low-energy X-ray detectors have a relatively thick entrance window which renders them practically useless below approximately 2.3 keV. A simple X-ray fluorescence experiment establishes clearly that the window is physically in the Ge material itself. Experiments with detectors made from different Ge crystals, and with Schottky barrier contacts of different metals indicate that the effect is due to a basic property of the transport of electrons near a surface. Theoretical considerations and a Monte Carlo calculation show that the window is caused by the escape of warm electrons which are the end product of a photo event. The mean free path of the electrons becomes longer as they lose energy by optical phonon collisions and they can be trapped at the surface before they are picked up by the electric field

    The purpose of this study is to determine whether a relationship exists between beginning nursing students' Nurse Entrance Test (NET) scores and their academic success within the first year of professional study. The major goal is to identify predictors of academic success so that supportive academic strategies could be implemented for the at-risk student. A statistically significant relationship is found between NET reading comprehension, math and composite scores and nursing grades during the first semester. Test-taking skills, social stressors and learning styles were also significantly related to course performance. Successful students had significantly higher reading, math, and composite scores and lower family and social stress scores than unsuccessful students. NET scores were also predictive of nursing grades, accounting for 10-33% of the variance when entered into a multiple regression equation. PMID:8286768

  12. Conjugate mixed convection in the entrance region of a symmetrically heated vertical channel with thick walls

    International Nuclear Information System (INIS)

    Conjugate mixed convection with buoyancy assisted laminar flow in the entrance region of a vertical channel is considered numerically. The problem is solved by a finite volume method for a thick walled, two-regional channel which has constant and uniform outside wall temperatures. The effects of wall thermal conduction as well as assisted buoyancy force on the flow and heat transfer are discussed in detail. Results are presented for a Prandtl number of 0.7, solid-to-fluid thermal conductivity ratios of 1≤ k* < ∞, wall thickness-to-channel length ratios of 0≤ l* ≤5, Reynolds numbers of 200≤ Re ≤1000, and for various Grashof numbers. The critical buoyancy parameter (Gr/Re), above which the flow reversal occurs, increases linearly with the increasing l*/k*, while it is independent on the Reynolds number. (authors)

  14. An assessment of methods for monitoring entrance surface dose in fluoroscopically guided interventional procedures

    International Nuclear Information System (INIS)

    In the light of a growing awareness of the risks of inducing skin injuries as a consequence of fluoroscopically guided interventional procedures (FGIPs), this paper compares three methods of monitoring entrance surface dose (ESD). It also reports measurements of ESDs made during the period August 1998 to June 1999 on 137 patients undergoing cardiac, neurological and general FGIPs. Although the sample is small, the results reinforce the need for routine assessments to be made of ESDs in FGIPs. At present, the most reliable and accurate form of ESD measurement would seem to be arrays of TLDs. However, transducer based methods, although likely to be less accurate, have considerable advantages in relation to a continuous monitoring programme. It is also suggested that there may be the potential locally for threshold dose area product (DAP) values to be set for specific procedures. These could be used to provide early warning of the potential for skin injuries. (author)

    Many educated adults possess exact mathematical abilities in addition to an approximate, intuitive sense of number, often referred to as the Approximate Number System (ANS). Here we investigate the link between ANS precision and mathematics performance in adults by testing participants on an ANS-precision test and collecting their scores on the Scholastic Aptitude Test (SAT), a standardized college-entrance exam in the USA. In two correlational studies, we found that ANS precision correlated with SAT-Quantitative (i.e., mathematics) scores. This relationship remained robust even when controlling for SAT-Verbal scores, suggesting a small but specific relationship between our primitive sense for number and formal mathematical abilities.

  16. Shell correction energy and the entrance channel effect on the formation of superheavy nuclei

    International Nuclear Information System (INIS)

    Based on the improved isospin dependent molecular dynamics model in which the shell correction energy of the system is calculated by using deformed two-center shell model and the surface energy of the system is improved by introducing a switch function that combines the surface energies of projectile and target with the one of the compound nucleus. The effects of the shell correction energy on synthesis of superheavy nuclei and the fusion cross sections in asymmetric and nearly symmetric reaction systems leading to the same compound nuclei 62Zn, 76Kr, and 202Pb are studied. The entrance channel mass asymmetry dependence of compound nucleus formation is found by analyzing the shell correction energies, Coulomb barriers and fusion cross sections. The experimental data are described quantitatively by the present model. It is found that the compound nucleus formation is favorable for the systems with larger mass asymmetry. (author)

  3. Entrance radiation doses during paediatric cardiac catheterizations performed for diagnosis or the treatment of congenital heart disease

    International Nuclear Information System (INIS)

    The purpose of this study was to estimate the radiation exposure of children, during cardiac catheterizations for the diagnosis or treatment of congenital heart disease. Radiation doses were estimated for 45 children aged from 1 d to 13 y old. Thermoluminescent dosemeters (TLDs) were used to estimate the posterior entrance dose (DP), the lateral entrance dose (DLAT), the thyroid dose and the gonads dose. A dose-area product (DAP) meter was also attached externally to the tube of the angiographic system and gave a direct value in mGy cm2 for each procedure. Posterior and lateral entrance dose values during cardiac catheterizations ranged from 1 to 197 mGy and from 1.1 to 250.3 mGy, respectively. Radiation exposure to the thyroid and the gonads ranged from 0.3 to 8.4 mGy to 0.1 and 0.7 mGy, respectively. Finally, the DAP meter values ranged between 360 and 33,200 mGy cm2. Radiation doses measured in this study are comparable with those reported to previous studies. Moreover, strong correlation was found between the DAP values and the entrance radiation dose measured with TLDs. (authors)

  8. The fresco at the entrance to Danilo II church of the Mother of God at Peć

    Directory of Open Access Journals (Sweden)

    Milanović Vesna

    2004-01-01

    Full Text Available Painted around 1330, this fresco is located on a large section of the western façade of the church of the Mother of God Hodegetria at Peć above the entrance that leads from the monumental narthex into the interior of the building. It is a composition, joining the unusual image of the holy patroness of Archbishop Danilo II's ecclesiastical endowment, accompanied by two figures of angels in adoration, to create an iconographic whole with a twin presentation of the archpriests, St. Nicolas and Danilo II himself bowing in prayer. After giving a careful and detailed description of the entire content and setting of the painting, first of all, the paper discusses the content and message conveyed in the choice of the image of the Mother of God with Child, which, in the given assembly of figures, is distinguished by its central position and enlarged proportions. A perception of the views maintained so far, regarding the interpretation of this composition, and the specific points related to the choice of the central figure, when attempting to decipher its meaning, leads to considering that in a certain reinterpretation of the aforesaid, quite specific representation of the patroness of the Serbian archbishop's church endowment, there also lies the key for the explanation of the twin presentation of the two hierarchs in prayer, as well as for shedding light on the inter-relationship of all the figures involved in the painting, i.e. for perceiving the logic of uniting them in one composition. Even though a new attempt at comprehending the content and the subtle message of the fresco largely rests upon the examination and thorough research of comparative material that previous research workers have already noted as being significant for the examination of the given solution, this does not hold for the conclusions arising from the observation of that material. There is a critical review particularly of the previous conclusions that remain within the

    This final report presents a review of the results of work done on behalf of the Swiss Federal Office of Energy (SFOE) on research into the possible uses of the rock water collected behind the tunnel linings of the new Gotthard base tunnel under the Swiss Alps. This report regards only the southern entrance. Estimates of the quantity of drainage water and its temperature are presented, as are possible uses for the warm water as a basis for a tropical greenhouse, fish breeding, a wellness-spa, district heating, and individual heat-pumps as well as for heating the Alp Transit visitor centre. Figures are quoted on effective heating-energy costs and reductions to be obtained in fossil fuel use. The high sensitivity of the energy price with respect to electricity prices and the degree to which buildings are connected to a district heating system is discussed. Possible use of the tunnel water in other municipalities in the area are also listed. Figures on heating-power and heating-energy supply are quoted for several of the various possible projects.

  10. Estimating pediatric entrance skin dose from digital radiography examination using DICOM metadata: A quality assurance tool

    2015-05-15

    Purpose: To develop an automated methodology to estimate patient examination dose in digital radiography (DR) imaging using DICOM metadata as a quality assurance (QA) tool. Methods: Patient examination and demographical information were gathered from metadata analysis of DICOM header data. The x-ray system radiation output (i.e., air KERMA) was characterized for all filter combinations used for patient examinations. Average patient thicknesses were measured for head, chest, abdomen, knees, and hands using volumetric images from CT. Backscatter factors (BSFs) were calculated from examination kVp. Patient entrance skin air KERMA (ESAK) was calculated by (1) looking up examination technique factors taken from DICOM header metadata (i.e., kVp and mA s) to derive an air KERMA (k{sub air}) value based on an x-ray characteristic radiation output curve; (2) scaling k{sub air} with a BSF value; and (3) correcting k{sub air} for patient thickness. Finally, patient entrance skin dose (ESD) was calculated by multiplying a mass–energy attenuation coefficient ratio by ESAK. Patient ESD calculations were computed for common DR examinations at our institution: dual view chest, anteroposterior (AP) abdomen, lateral (LAT) skull, dual view knee, and bone age (left hand only) examinations. Results: ESD was calculated for a total of 3794 patients; mean age was 11 ± 8 yr (range: 2 months to 55 yr). The mean ESD range was 0.19–0.42 mGy for dual view chest, 0.28–1.2 mGy for AP abdomen, 0.18–0.65 mGy for LAT view skull, 0.15–0.63 mGy for dual view knee, and 0.10–0.12 mGy for bone age (left hand) examinations. Conclusions: A methodology combining DICOM header metadata and basic x-ray tube characterization curves was demonstrated. In a regulatory era where patient dose reporting has become increasingly in demand, this methodology will allow a knowledgeable user the means to establish an automatable dose reporting program for DR and perform patient dose related QA testing for

    1997-12-01

    The purposes of this study were to investigate the furcation entrance angle (FEA) and the distance between cemento-enamel junction (CEJ) and furcation entrance (FE) of the extracted maxillary and mandibular molars. Assay teeth comprised 89 maxillary molars and 93 mandibular molars. All the FEAs and CEJ-FEs of the molars were measured by a stereomicroscope at 2.5 x equipped with a Bioscan OPTIMAS Image Analyzer (BOIA). The results were summarized as follows: (1) The mean FEAs in the buccal, mesial and distal furcations were 96.3 +/- 10.0, 103.8 +/- 9.7, and 107.2 +/- 12.2 degrees in the maxillary molars, and 91.6 +/- 11.7, 101.7 +/- 11.5, and 97.1 +/- 10.7 degrees in the maxillary second molars, respectively. At the buccal and lingual furcations of mandibular first and second molars, they measured 100.5 +/- 9.7/102.7 +/- 8.5, and 93.3 +/- 11.5/91.7 +/- 10.8 degrees, respectively. (2) The mean distance of CEJ-FEs at the buccal, mesial and distal furcations of maxillary molars were 3.42 +/- 1.5mm, 3.55 +/- 0.97 mm, and 3.69 +/- 0.98mm for the first molars, and 3.01 +/- 1.04mm, 4.04 +/- 1.58mm and 3.00 +/- 1.14mm for the second molars. At the buccal and lingual furcations of the mandibular first and second molars, they were recorded as 1.90 +/- 0.08mm and 2.90 +/- 0.07mm, and 2.82 +/- 1.34mm and 3.46 +/- 1.03mm, respectively. It was concluded that buccal FEA of maxillary 2nd molar was the smallest (91.56 +/- 9.68 degrees) as compared to the mesial and distal FEAs; whereas the mean distance of CEJ-FEs at the buccal surface was the smallest (1.90mm +/- 0.08mm) when compared to the others.

  17. Jackson Park Hospital Green Building Medical Center

    2010-03-31

    Jackson Park Hospital completed the construction of a new Medical Office Building on its campus this spring. The new building construction has adopted the City of Chicago's recent focus on protecting the environment, and conserving energy and resources, with the introduction of green building codes. Located in a poor, inner city neighborhood on the South side of Chicago, Jackson Park Hospital has chosen green building strategies to help make the area a better place to live and work. The new green building houses the hospital's Family Medicine Residency Program and Specialty Medical Offices. The residency program has been vital in attracting new, young physicians to this medically underserved area. The new outpatient center will also help to allure needed medical providers to the community. The facility also has areas designated to women's health and community education. The Community Education Conference Room will provide learning opportunities to area residents. Emphasis will be placed on conserving resources and protecting our environment, as well as providing information on healthcare access and preventive medicine. The new Medical Office Building was constructed with numerous energy saving features. The exterior cladding of the building is an innovative, locally-manufactured precast concrete panel system with integral insulation that achieves an R-value in excess of building code requirements. The roof is a 'green roof' covered by native plantings, lessening the impact solar heat gain on the building, and reducing air conditioning requirements. The windows are low-E, tinted, and insulated to reduce cooling requirements in summer and heating requirements in winter. The main entrance has an air lock to prevent unconditioned air from entering the building and impacting interior air temperatures. Since much of the traffic in and out of the office building comes from the adjacent Jackson Park Hospital, a pedestrian bridge connects the two

  18. Entrance surface air kerma in x-ray systems for paediatric interventional cardiology: a national survey

    International Nuclear Information System (INIS)

    The aims of this work were to report the results of a national survey on entrance surface air kerma (ESAK) values for different phantom thicknesses and operation modes in paediatric interventional cardiology (IC) systems and to compare them with previous values. The national survey also offers suggested investigation levels (ILs) for ESAK in paediatric cardiac procedures. ESAK was measured on phantoms of 4-16 cm thickness of polymethyl methacrylate slabs. For low fluoroscopy mode (FM), ESAK rates ranged from 0.11 to 33.1 mGy min-1 and for high FM from 0.34 to 61.0 mGy min-1. For cine mode, values of ESAK per frame were from 1.9 to 78.2 μGy fr-1. The ILs were suggested as the third quartile of the values measured. This research showed lower ESAK values than in previous research, particularly for ESAK values in cine modes. This work represents a first step towards launching a national programme in paediatric dosimetry for IC procedures. (authors)

  19. On the optimum entrance reaction channel for the synthesis of superheavy elements

    International Nuclear Information System (INIS)

    Using the three-dimensional Langevin equation and the one- or two-dimensional Smoluchovski equation, a time developpement of a nuclear shape of reaction system including the configuration concerning with the process of kinetic energy dissipation, has been calculated to get the evaporation residue cross section for several reaction channels in superheavy mass region around Z=114. The calculation is extremely time consuming and it is not easy impossible to search systematically the optimum reaction channel for the of new elements. In order to contribute to the effective preliminary investigation which entrance channel is more suitable for the synthesis of elements in superheavy mass region, we propose an empirical cross section formula which is derived from the knowledge obtained so far in our calculations. This formula is a kind of extrapolation from region around Z=114 to the other mass region, and is useful for not only experimentalists but theoreticians to proceed their investigation to the next step. The validity and the essential point of the open problem concerning with the fusion-fission dynamics in superheavy mass region are reported. This formula will be a great help for understanding which quantities determine the evaporation residue cross section and how the behaviour of there quantities connect with the physical concept.

  20. Evaluation of the entrance surface air kerma in mammographic examinations in Rio de Janeiro (Brazil)

    International Nuclear Information System (INIS)

    The aim of this work was to evaluate the distribution of the entrance surface air kerma (ESAK) and the average glandular dose (DG) in four mammography facilities located in the city of Rio de Janeiro. The ESAK values were estimated from the X-ray tube output rate (mGy/mAs) parameters. The image quality was evaluated by the radiologists in each clinic. The ESAK values obtained for a breast thickness of 45 mm were 5.58 mGy in Clinic A, 10.07 mGy in Clinic B, 13.89 mGy in Clinic C and 7.21 mGy in Clinic D. For DG, it can be seen that, for the same compressed breast thickness (50 mm), the value varied from 0.20 to 3.60 mGy, with a mean value of 1.50 mGy for all the clinics. In image quality evaluation, Clinic D was the only one that presented a very low acceptability for quality criteria and inadequacies in relation to specks, masses and optical density. (authors)

  1. Search for entrance channel effects in heavy ion induced fusion reactions via neutron evaporation

    International Nuclear Information System (INIS)

    Neutrons from the fusion reactions 16O+64Zn at 91 MeV and 32S+48Ti at 120 and 125 MeV have been observed in two series of complementary experiments using the time of flight technique. The energies are selected so that both the systems lead to the compound nucleus 80Sr* with the same value of the angular momentum and the excitation energy. The spectra from the asymmetric reaction 16O+64Zn are found to be consistent with the predictions of the statistical model calculations using rotating liquid drop model values of the moment of inertia and the transmission coefficients for the spherical nuclei in the inverse absorption channel. However, the experimental spectra in the case of the symmetric reaction 32S+48Ti show deviations at higher as well as lower energies from the normal statistical model calculations. This indicates the effect of the entrance channel on the dynamics of the neutron evaporation of the compound system. The effective level density parameter a is found to be smaller, indicating the evaporation at a higher temperature, for the same compound nucleus formed in the case of the symmetric system as compared to the asymmetric system

  2. Soft x-ray images of the Laser Entrance Hole of NIC Hohlraums (paper, HTPD2012)

    Schneider, M B; Meezan, N B

    2012-04-30

    Hohlraums at the National Ignition Facility convert laser energy into a thermal x-radiation drive, which implodes the capsule, thus compressing the fuel. The x-radiation drive is measured with a low resolution, time-resolved x-ray spectrometer that views the hohlraum's laser entrance hole (LEH) at 37{sup o} to the hohlraum axis. This measurement has no spatial resolution. To convert this to the drive inside the hohlraum, the area and fraction of the measured x-radiation which comes from the region inside the hohlraum must be known. The size of the LEH is measured with the time integrated Static X-ray Imager (SXI) which view the LEH at 18{sup o} to the hohlraum axis. A soft x-ray image has been added to the SXI to measure the fraction of x-radiation inside the LEH's Clear Aperture in order to correct the measured radiation. A multilayer mirror plus filter selects an x-ray band centered at 870 eV, near the x-ray energy peak of a 300 eV blackbody. Results from this channel and corrections to the x-radiation drive are discussed.

  3. Evaluation of a Model for Predicting the Tidal Velocity in Fjord Entrances

    Directory of Open Access Journals (Sweden)

    Paul Thomassen

    2013-04-01

    Full Text Available Sufficiently accurate and low-cost estimation of tidal velocities is of importance when evaluating a potential site for a tidal energy farm. Here we suggest and evaluate a model to calculate the tidal velocity in fjord entrances. The model is compared with tidal velocities from Acoustic Doppler Current Profiler (ADCP measurements in the tidal channel Skarpsundet in Norway. The calculated velocity value from the model corresponded well with the measured cross-sectional average velocity, but was shown to underestimate the velocity in the centre of the channel. The effect of this was quantified by calculating the kinetic energy of the flow for a 14-day period. A numerical simulation using TELEMAC-2D was performed and validated with ADCP measurements. Velocity data from the simulation was used as input for calculating the kinetic energy at various locations in the channel. It was concluded that the model presented here is not accurate enough for assessing the tidal energy resource. However, the simplicity of the model was considered promising in the use of finding sites where further analyses can be made.

  4. The entrance system laboratory prototype for an advanced mass and ionic charge composition experiment

    International Nuclear Information System (INIS)

    Electrostatic analyzers (ESA) have been used extensively for the characterization of plasmas in a variety of space environments. They vary in shape, geometry, and size and are adapted to the specific particle population to be measured and the configuration of the spacecraft. Their main function is to select the energy per charge of the particles within a passband. An energy-per-charge range larger than that of the passband can be sampled by varying the voltage difference between the ESA electrodes. The voltage sweep takes time and reduces the duty cycle for a particular energy-per-charge passband. Our design approach for an advanced mass and ionic charge composition experiment (AMICCE) has a novel electrostatic analyzer that essentially serves as a spectrograph and selects ions simultaneously over a broad range of energy-per-charge (E/q). Only three voltage settings are required to cover the entire range from ∼10 to 270 keV/q, thus dramatically increasing the product of the geometric factor times the duty cycle when compared with other instruments. In this paper, we describe the AMICCE concept with particular emphasis on the prototype of the entrance system (ESA and collimator), which we designed, developed, and tested. We also present comparisons of the laboratory results with electrostatic simulations.

In the case of sup 2 sup 8 Si+ sup 2 sup 7 Al symmetric system, the experimental spectra deviate at higher as well as at lower en...

  6. Entrance channel effects on preequilibrium emission and incomplete fusion in Promptly Emitted Particle model

    International Nuclear Information System (INIS)

    In intermediate energy heavy ion collision prompt particles emitted in the early stages of the reaction affect the properties of the incompletely fused composite. We have studied the entrance channel effects on preequilibrium proton emission and various observables, like temperature, residual velocity, and linear momentum transfer of the incompletely fused residue, in the framework of Promptly Emitted Particle (PEP) model. The calculated preequilibrium proton energy spectra for Oxygen and Sulphur induced reactions on various targets have been confronted with the respective experimental data and the agreement between the two has been found to be quite satisfactory. Proton multiplicity has been found to decrease/increase with the increase in target/projectile mass. Residual velocity and linear momentum transfer have been found to have weak dependance on target mass. With the increase in incident energy, the calculation predicts a tendency towards limiting the temperature of the residue for all the target masses. The limiting temperature has been found to decrease with increase in the mass of the residue which is in accordance with the experimental observations. (orig.)

  7. Optimal Coordinated Control of Power Extraction in LES of a Wind Farm with Entrance Effects

    Directory of Open Access Journals (Sweden)

    Jay P. Goit

    2016-01-01

    Full Text Available We investigate the use of optimal coordinated control techniques in large eddy simulations of wind farm boundary layer interaction with the aim of increasing the total energy extraction in wind farms. The individual wind turbines are considered as flow actuators, and their energy extraction is dynamically regulated in time, so as to optimally influence the flow field. We extend earlier work on wind farm optimal control in the fully-developed regime (Goit and Meyers 2015, J. Fluid Mech. 768, 5–50 to a ‘finite’ wind farm case, in which entrance effects play an important role. For the optimal control, a receding horizon framework is employed in which turbine thrust coefficients are optimized in time and per turbine. Optimization is performed with a conjugate gradient method, where gradients of the cost functional are obtained using adjoint large eddy simulations. Overall, the energy extraction is increased 7% by the optimal control. This increase in energy extraction is related to faster wake recovery throughout the farm. For the first row of turbines, the optimal control increases turbulence levels and Reynolds stresses in the wake, leading to better wake mixing and an inflow velocity for the second row that is significantly higher than in the uncontrolled case. For downstream rows, the optimal control mainly enhances the sideways mean transport of momentum. This is different from earlier observations by Goit and Meyers (2015 in the fully-developed regime, where mainly vertical transport was enhanced.

  9. Entrance channel influence on the formation and decay of hot nuclei

    International Nuclear Information System (INIS)

    Different entrance channels have been investigated to form very hot nuclei and to study their decay properties. i) Argon and Nickel projectiles accelerated around the Fermi energy show that central collisions induce momentum transfers to target nuclei which are proportional to the mass of the projectile and not to its velocities in the studied energy range. The preequilibrium model fits nicely the experimental results. The decay properties of the fission products for hot nuclei will be presented. Both head-on collisions and peripheral massive transfers contribute to the formation of very excited nuclei. The question of the influence of the energy deposit in the composite like system in limiting their yields is discussed. ii) Investigations have been also achieved with alpha projectiles at much higher incident energy (around 1 GeV/u). It is shown that hot and thermalized nuclei are also formed even when the nucleon-nucleon collisions are predominant. A sensitive parameter of the transition from binary fission to multifragmentation seems to be the energy deposit in the target residues rather than the projectile velocity

  10. Experimental study of fluid flow in the entrance of a sinusoidal channel

    International Nuclear Information System (INIS)

    An experimental flow visualization study of the entrance section of channels formed with sinusoidal plates was made. The experiments were conducted in a water tunnel and a laser illuminated particle tracking was used as the technique of flow visualization. The geometric parameters of the plates were maintained constant while the distance between plates, phase angle, and the Reynolds number were varied during the experiments. The flow regimes that were found in the experiments are steady, unsteady and significantly-mixed flows. Instabilities of the flow first appear near the exit of the channel, and move closer to the inlet waves as the Reynolds number grows, but in the first wave from inlet the flow is always steady. The results show that, for all other parameters fixed, the Reynolds number at which unsteady flow first appears grows with the distance between plates. The phase angle that best promotes unsteady flow depends on the average distance between plates: for certain average distance between plates, there is a phase angle that best disturbs the flow. For the set of parameters used in this experiment, a channel with eight waves is sufficiently long and the flow features presented in the first eight waves of a longer channel will be similar to what was observed here

The following four kinds of the bullets were tested: "the fireball", "Luman cap 0.3", "Luman Field Target 0.68" and "DIABOLO". It was experimentally shown that the injurious action of the bullets fired from the same distance from the pneumatic weapons depends on the type of both the bullet and the weapon, as well as the properties of the target material. Specifically, the action of bullets fired from the piston pneumatic rifle remained stable whereas that of the bullets shot from the gas-balloon air pistol decreased as the gas was exhausted. The studies by the contact-diffusion method have demonstrated that the entrance bullet holes created by the shots from pneumatic weapons are surrounded by dispersed metal particles which makes it possible to estimate the shooting distance. Moreover, the bullets fired from the pneumatic weapons leave the muzzle face imprint on certain target materials. PMID:26036066

  13. Rate air Kerma entrance skin of patients undergoing hemodynamic procedures in the State of Santa Catarina, Brazil

    International Nuclear Information System (INIS)

    This paper presents the results of the measured values of the skin entrance Air Kerma Rate in patients submitted to hemodynamic procedures, in the State of Santa Catarina, using as limit values set by the International Basic Safety Standards Guide, published by the International Atomic Energy Agency (IAEA ), and comparing them to the limits established by the Ordinance No. 453/1998. Tests were performed to measure the rate of Kerma skin entrance in 13 hemodynamic equipment in 10 hospitals in the state of Santa Catarina, between January 2011 and December 2012, in hemodynamic operated through fluoroscopy mode. Among the evaluated equipment, 77% disagree with the limits established in the International Basic Safety Standards, however, if compared the values of the Air Kerma rate obtained with the limit established by Ordinance No. 453, 100% of the devices are approved. The results obtained in this paper suggest the need for revision of the Ordinance No. 453/1998, by the regulatory agencies. (author)

  14. Oil droplet behavior at a pore entrance in the presence of crossflow: Implications for microfiltration of oil-water dispersions

    Darvishzadeh, Tohid; Priezjev, Nikolai V

    2013-01-01

    The behavior of an oil droplet pinned at the entrance of a micropore and subject to clossflow-induced shear is investigated numerically by solving the Navier-Stokes equation. We found that in the absence of crossflow, the critical transmembrane pressure required to force the droplet into the pore is in excellent agreement with a theoretical prediction based on the Young-Laplace equation. With increasing shear rate, the critical pressure of permeation increases, and at sufficiently high shear rates the oil droplet breaks up into two segments. The results of numerical simulations indicate that droplet breakup at the pore entrance is facilitated at lower surface tension, higher oil-to-water viscosity ratio and larger droplet size but is insensitive to the value of the contact angle. Using simple force and torque balance arguments, an estimate for the increase in critical pressure due to crossflow and the breakup capillary number is obtained and validated for different viscosity ratios, surface tension coefficien...

  1. Methods for implementation of in vivo dosimetry (entrance dose) using thermoluminescent dosimeters during radiotherapy treatment with photon beam

    International Nuclear Information System (INIS)

    Selection, calibration procedure to convert TLD signal into absorbed dose and physical characteristics at the thermoluminescent dosimeters, as well as the determination of correction factors and the methodology to determine expected entrance dose, are described in this work. Practical aspects and the utility of entrance dose measures with thermoluminescent dosimeters were investigated, as well as the exactness and the reproducibility of the daily dose release. The entrance dose measures were performed in five patients with diagnosis of breast cancer treated with a 6 MV photon beam. The measured dose and the expected dose values agreed in ± 5%, due to excellent treatment equipment stability, to automatic verification system and the good exactness in the daily treatment adjustment. Good precision can be achieved when the correction factors for each parameter of influence in the dosimeter response are carefully determined and applied to convert the thermoluminescent signal into absorbed dose. The study demonstrates the viability of thermoluminescent dosimeters use for in vivo dosimetry and its utility as part of a quality assurance program in a radiation therapy service. (author)

  2. A numerical investigation of entropy generation in the entrance region of curved pipes at constant wall temperature

    International Nuclear Information System (INIS)

    In this study, developing incompressible viscous flow and heat transfer in the curved pipes are studied numerically to analyze the entropy generation and thermodynamic optimization in the entrance region at a constant wall temperature. The governing equations including continuity, momentum and energy equations are solved using a second order finite difference method based on the projection algorithm. Entropy generation and optimal Reynolds number calculation based on the entropy generation minimization are carried out for two cases considering the two groups of non-dimensional parameters both numerically and analytically. The comparison of the numerical results in the entrance region with the analytical ones in the fully developed region indicates that both solutions predict nearly the same optimal Reynolds numbers, specially, for the first group of the non-dimensional parameters. -- Highlights: → Numerical study of a three dimensional developing incompressible viscous flow in curved pipes with a constant wall temperature. → Entropy generation and optimal Reynolds number calculation based on the entropy generation minimization. → Entrance region are compared with the analytical prediction in the fully developed region. → Prediction of nearly the same optimal Reynolds for developing and fully developed region in curved pipe flows.

    Full Text Available The aim of this cross-sectional study is to explore certain factors effecting the points of university entrance examination of first class students, the relationship between the points and domestic violence the have been exposed last year and the attitudes of students towards domestic violence. Total 316 students were included in the study. The mean points of university entrance examination was found higher in girl students, students who do not smoke and graduated from Anatolian, Science and Private High Schools. 1/3rd of the the students included to the study was found that they were experienced or exposed domestic violence within last year and the violence was most often between parents and kids. It was determined that the students whose parents experienced domestic violence in the past has been exposed domestic violence more frequently. The students who think violence as a child education method were the students whose parents experienced domestic violence in the past, boy students and the students who somoke. The hypothesis “students exposed to domestic violence may have low points from the university entrance examination” can not be supported. Domestic violence in the students who smoke must be researched because of they think that violence may be a method in child education. This study reveals that who experiences domestic violence puts it in practice at later ages as if violence were a normal behaviour. [TAF Prev Med Bull 2006; 5(3.000: 176-186

  4. 14C-2-deoxyglucose uptake in the ground squirrel brain during entrance to and arousal from hibernation

    International Nuclear Information System (INIS)

    Neuronal activity underlying various phases of the mammalian hibernation cycle was investigated using the 14C-2-deoxyglucose (2DG) method. Relative 2DG uptake (R2DGU) values were computed for 96 brain regions across 7 phases of the hibernation cycle: euthermia, 3 body temperature (Tb) intervals during entrance into hibernation, stable deep hibernation, and 2 Tb intervals during arousal from hibernation. Multivariate statistical techniques were employed to identify objectively groups of brain regions whose R2DGU values showed a similar pattern across all phases of hibernation. Factor analysis revealed that most of the variability in R2DGU values for the 96 brain regions across the entire cycle could be accounted for by 3 principal factors. These factors could accurately discriminate the various phases of hibernation on the basis of the R2DGU values alone. Three hypothalamic and 3 cortical regions were identified as possibly mediating the entrance into hibernation because they underwent a change in R2DGU early in entrance into hibernation and loaded strongly on one of the principal factors. Another 4 hypothalamic regions were similarly identified as possibly causally involved in the arousal from hibernation. These results, coupled with characteristic changes in ordinal rank of the 96 brain regions in each phase of hibernation, support the concept that mammalian hibernation is an active, integrated orchestration of neurophysiological events rather than a state entered through a passive process

  5. Patient entrance skin doses in diagnostic radiology at Groote Schuur Hospital

    International Nuclear Information System (INIS)

    Full text: Assessment and optimization of the radiation dose received by patients in diagnostic radiology are important tasks in radiological protection. Patient exposure assessment is necessary to keeping an awareness of exposure, to establish guidance levels by means of surveys, to use guidance levels as reference to compare with at individual facilities, to apply methods of dose reductions and optimizations of protection and to assess population doses. This survey of patient doses at Groote Schuur Hospital served the following purpose: a) To establish guidance levels; b) To compare doses for the same type of examination, done with different exposure parameters or with different equipment; c) To compare patient exposures for different types of examinations; and d) To assess relative contributions to collective doses from various types of examinations. The need to optimize the protection of patients results from the fact that medical exposures are by far the largest source of radiation exposure. One aid in minimizing unnecessary exposure in diagnostic imaging is through the use of patient exposure guidelines. Radiation protection of patients is based on the application of the two major radiation protection principles, i.e. justification and optimisation. In order to evaluate that procedures are effectively optimised and remain optimised as time passes, it is necessary to establish quantitative indicators regarding the doses delivered. Entrance skin doses were measured for a number of diagnostic examinations. When compared with similar studies in other countries, a large variation in dose was observed, particularly for chest and abdomen examinations. Actions taken in other countries which led to a significant dose reduction will also be presented. In summary, it seems that it is possible to develop reference values for a wide range of common examinations and use them as investigation levels. (author)

  6. Assessment of entrance surface dose and health risk from common radiology examinations in Iran

    International Nuclear Information System (INIS)

    Medical X-ray exposures are the largest man-made source of population exposure to ionising radiation in many countries. Although information on medical exposure is already incorporated into national legislative documents, in Isfahan there is no data on the assessment of patient's entrance surface dose (ESD) and the health risk from conventional radiography in daily clinical practice. The aim of this study was to investigate ESDs and the consequent health risk for the patients undergoing routine X-ray procedures in hospitals under the control of Isfahan University of Medical Sciences, Iran, in year 2011. The values of ESDs were measured for common radiographical examinations with the highest absorbed dose to the patient in seven hospitals (Alzahra, Ashrafi-Khomeini-shahr, Feyz, Isabne-Maryam, Kashani, Nour-Aliasghar and Seyed-Al Shohada) and six stationary X-ray machines (General Electric, USA; Phillips, The Netherlands; Siemens, Germany; Shimadzu (Japan)); Toshiba (Japan)) and Varian, USA). The results of the ESD measurements as well as the calculated effective dose values between different X-ray examinations showed values significantly greater than those recorded in some other countries especially for the high tube potential technique (such as the skull) by factors of 2.5-5.0. Based on the fatality risk of 5 % per sievert, it was estimated that, for chest and skull examinations approximately two (40.18 person-Sv x 5 % per sievert) and one (2.53 person-Sv x 5 % per sievert) cases of health risk, respectively, may in the future be attributable to diagnostic X rays done in year 2011 in Isfahan. Efforts should be taken to further lower patient doses while securing image quality. The need to provide relevant education and training to staff in the radiology sections is of utmost importance.

    Anett K Larsen

    Full Text Available Marine mammal Brucella spp. have been isolated from pinnipeds (B. pinnipedialis and cetaceans (B. ceti from around the world. Although the zoonotic potential of marine mammal brucellae is largely unknown, reports of human disease exist. There are few studies of the mechanisms of bacterial intracellular invasion and multiplication involving the marine mammal Brucella spp. We examined the infective capacity of two genetically different B. pinnipedialis strains (reference strain; NTCT 12890 and a hooded seal isolate; B17 by measuring the ability of the bacteria to enter and replicate in cultured phagocytes and epithelial cells. Human macrophage-like cells (THP-1, two murine macrophage cell lines (RAW264.7 and J774A.1, and a human malignant epithelial cell line (HeLa S3 were challenged with bacteria in a gentamicin protection assay. Our results show that B. pinnipedialis is internalized, but is then gradually eliminated during the next 72-96 hours. Confocal microscopy revealed that intracellular B. pinnipedialis hooded seal strain colocalized with lysosomal compartments at 1.5 and 24 hours after infection. Intracellular presence of B. pinnipedialis hooded seal strain was verified by transmission electron microscopy. By using a cholesterol-scavenging lipid inhibitor, entrance of B. pinnipedialis hooded seal strain in human macrophages was significantly reduced by 65.8 % (± 17.3, suggesting involvement of lipid-rafts in intracellular entry. Murine macrophages invaded by B. pinnipedialis do not release nitric oxide (NO and intracellular bacterial presence does not induce cell death. In summary, B. pinnipedialis hooded seal strain can enter human and murine macrophages, as well as human epithelial cells. Intracellular entry of B. pinnipedialis hooded seal strain involves, but seems not to be limited to, lipid-rafts in human macrophages. Brucella pinnipedialis does not multiply or survive for prolonged periods intracellulary.

  8. Direct measurement of a patient's entrance skin dose during pediatric cardiac catheterization

    International Nuclear Information System (INIS)

    Children with complex congenital heart diseases often require repeated cardiac catheterization; however, children are more radiosensitive than adults. Therefore, radiation-induced carcinogenesis is an important consideration for children who undergo those procedures. We measured entrance skin doses (ESDs) using radio-photoluminescence dosimeter (RPLD) chips during cardiac catheterization for 15 pediatric patients (median age, 1.92 years; males, n = 9; females, n = 6) with cardiac diseases. Four RPLD chips were placed on the patient's posterior and right side of the chest. Correlations between maximum ESD and dose-area products (DAP), total number of frames, total fluoroscopic time, number of cine runs, cumulative dose at the interventional reference point (IRP), body weight, chest thickness, and height were analyzed. The maximum ESD was 80 ± 59 (mean ± standard deviation) mGy. Maximum ESD closely correlated with both DAP (r = 0.78) and cumulative dose at the IRP (r = 0.82). Maximum ESD for coiling and ballooning tended to be higher than that for ablation, balloon atrial septostomy, and diagnostic procedures. In conclusion, we directly measured ESD using RPLD chips and found that maximum ESD could be estimated in real-time using angiographic parameters, such as DAP and cumulative dose at the IRP. Children requiring repeated catheterizations would be exposed to high radiation levels throughout their lives, although treatment influences radiation dose. Therefore, the radiation dose associated with individual cardiac catheterizations should be analyzed, and the effects of radiation throughout the lives of such patients should be followed. (author)

    When visiting multiple tourist scenic spots, a recommended travel line is usually the most effective route designed for tourists according to the actual road situations. In the field of intelligent tourism navigation, a traditional recommended travel line is mainly generated by path planning algorithm automatically, considering thescenic spots’positions and road networks based on graph model. Normally, the traditional algorithms firstly map scenic spots (which belong to certain scenic area) into points of interests (POIs),and map the road network that links these POIs into a line collection, then build the corresponding graph model. But when a scenic spot has a limited area and involves multiple entrances or exits(for example buildings with multiple indoor space), the tra-ditional described mechanism for single point coordinates is difficult to reflect these structural features. In reali-ty, scenic area path planning is widely applied in the field of mobile tourism guide recently, especially for pedes-trians. There exist significant differences between theoretical optimal paths and actual optimal paths, sincetourist-sare inclined to have more choices. In order to solve this problem, this paper analyzed various influences on the process of path planning, caused by scenic spots’own structural features (such as the size, shape and entrance), and focused on the influences of multiple entrances or exits located within the scenic area. Then,we proposed a Double-Weighted Graph Model considering multiple entrances and exits for tourist scenic area, and the weights of both vertexes and edges of the proposed model can be selected and weighted dynamically. Next, we discussed the building method for the model, and proposed an optimal path planning algorithm based on Dijkstra algorithm and Prim algorithm. Experimental results show that the optimal planned travel line derived from this proposed model and algorithms is considerably reasonable, and the travelling order and

  15. Study of angular momentum variation due to entrance channel effect in heavy ion fusion reactions

    Science.gov (United States)

    Kumar, Ajay

    2014-05-01

    A systematic investigation of the properties of hot nuclei may be studied by detecting the evaporated particles. These emissions reflect the behavior of the nucleus at various stages of the deexcitation cascade. When the nucleus is formed by the collision of a heavy nucleus with a light particle, the statistical model has done a good job of predicting the distribution of evaporated particles when reasonable choices were made for the level densities and yrast lines. Comparison to more specific measurements could, of course, provide a more severe test of the model and enable one to identify the deviations from the statistical model as the signature of other effects not included in the model. Some papers have claimed that experimental evaporation spectra from heavy-ion fusion reactions at higher excitation energies and angular momenta are no longer consistent with the predictions of the standard statistical model. In order to confirm this prediction we have employed two systems, a mass-symmetric (31P+45Sc) and a mass-asymmetric channel (12C+64Zn), leading to the same compound nucleus 76Kr* at the excitation energy of 75 MeV. Neutron energy spectra of the asymmetric system (12C+64Zn) at different angles are well described by the statistical model predictions using the normal value of the level density parameter a = A/8 MeV-1. However, in the case of the symmetric system (31P+45Sc), the statistical model interpretation of the data requires the change in the value of a = A/10 MeV-1. The delayed evolution of the compound system in case of the symmetric 31P+45Sc system may lead to the formation of a temperature equilibrated dinuclear complex, which may be responsible for the neutron emission at higher temperature, while the protons and alpha particles are evaporated after neutron emission when the system is sufficiently cooled down and the higher g-values do not contribute in the formation of the compound nucleus for the symmetric entrance channel in case of charged

    2005-05-01

    In November 2004, two high resolution hydrographic sections were occupied at the entrance to the Gulf of California. One section combined velocity data collected with a 300 kHz broadband ADCP with water properties obtained by a CTD which continuously profiled the upper 125 m. The second section combined velocity data collected with a 75 kHz ocean surveyor ADCP with traditional 1000 dbar CTD casts. As with previous sections, inflow was observed along Sinola but outflow occurred in the center third of the section. This meant that the isopycnal dome was located in the eastern half of section at 108.5W. Flow patterns and rates derived from ADCP measurements were in good agreement with those derived from geostrophy. Inflow and outflow extended from the surface to about 700 dbar. The maximum inflow (outflow) was about 35-40 cm/s (20 cm/s) between 100-200 (100-200) dbar and 108.2-108.4W (108.5-108.9W). Unlike previous sections, the portion of the section next to Baja California was marked by weak inflow. Waters in the upper layer were roughly divided into two classes by the isohaline S=34.7. To the east, Tropical Surface Waters (S greater than 34.3) lay between 50 and 90 dbar while to the west, Gulf waters (S less than 34.9) were observed. The Triaxus section showed the high resolution details (0.5 km horizontal and 0.5 dbar vertical) of the upper ocean structure. Highest productivity was observed at the base of the mixed layer in the western portion of the section where the warmest and highest salinity waters were found. Below the mixed layer, the fine structure of Subtropical Subsurface Waters formed in the Gulf is seen at depth along the 25.5 and 26.0 kg/m3 isopycnals. The separation between Tropical Surface and Gulf Waters was nearly vertical along 108.6W and marked by the zero isotach of cross stream flow as well as the zero isotach of inflow between 70 and 100 m.

    2016-07-01

    Background: It is well known that the anomalous behavior of angular anisotropies of fission fragments at sub- and near-barrier energies is associated with a memory of conditions in the entrance channel of the heavy-ion reactions, particularly, deformations and spins of colliding nuclei that determine the initial distributions for the components of the total angular momentum over the symmetry axis of the fissioning system and the beam axis. Purpose: We develop a new dynamic approach, which allows the description of the memory effects in the fission fragment angular distributions and provides new information on fusion and fission dynamics. Methods: The approach is based on the dynamic model of the fission fragment angular distributions which takes into account stochastic aspects of nuclear fission and thermal fluctuations for the tilting mode that is characterized by the projection of the total angular momentum onto the symmetry axis of the fissioning system. Another base of our approach is the quantum mechanical method to calculate the initial distributions over the components of the total angular momentum of the nuclear system immediately following complete fusion. Results: A method is suggested for calculating the initial distributions of the total angular momentum projection onto the symmetry axis for the nuclear systems formed in the reactions of complete fusion of deformed nuclei with spins. The angular distributions of fission fragments for the 16O+232Th,12C+235,236,238, and 13C+235U reactions have been analyzed within the dynamic approach over a range of sub- and above-barrier energies. The analysis allowed us to determine the relaxation time for the tilting mode and the fraction of fission events occurring in times not larger than the relaxation time for the tilting mode. Conclusions: It is shown that the memory effects play an important role in the formation of the angular distributions of fission fragments for the reactions induced by heavy ions. The

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

  1. Building trust

    International Nuclear Information System (INIS)

    'Activate' is the energy magazine for secondary schools and is part of the Education Programme which is managed on behalf of the British Nuclear Industry Forum by AEA Technology. activate is the flagship communication device between the British Nuclear Industry Forum's Education Programme and secondary schools in the UK. It was developed from a previous publication, Nuclear Bulletin. There is a need for the nuclear industry to build trust with teachers and students in the UK, where for a long time, everything that the industry has said, written or printed has been disregarded by school teachers as propaganda. Over the last few years the industry has put in a great deal of effort to position itself as a provider of educationally sound and socially acceptable information. 'Activate' was an evolution of this idea and there was a hole in the market for a lively, activity and article based magazine that could be used in the classroom. The target audience is principally teachers of science, mathematics and geography, but also includes teachers of art,, English and history with students of between 11 and 18. The results were very positive in that teachers appreciated the colourful and lively nature of activate and they felt that it provided information and opinions in an un biased and non-propagandist way. Their comments about layout, number of activities style of presentation were taken into account and during the summer of 1994 activate was remodelled ready for re launch in September. The feedback so far is good with more teachers signing up every week to receive their own free copy

    Toxoplasma gondii is a protozoan with worldwide distribution and in spite of increasing information about its biology, treatment of toxoplasmosis is restricted to a few drugs and unfortunately using of each of drugs is associated with significant side effects in patients. This study was designed to evaluate the efficacy of cromolyn sodium and ketotifen as alternative drugs for the treatment of toxoplasmosis. In vitro; in case group, concentrations of 1, 5, 10 and 15 µg/ml of ketotifen and cromolyn sodium were added to RPMI medium containing peritoneal macrophages. After 1 h incubation and adding tachyzoites to medium, efficacy rate of these drugs in entrance inhibition of Toxoplasma tachyzoites into macrophages were evaluated after 30 and 60 min. In vivo; case groups received ketotifen and cromolyn sodium with different concentrations at various times. Control groups received none of drugs. We found that in vitro; after 60 min the best efficacy of these drugs in inhibition of cell entrance of Toxoplasma was observed at 15 µg/ml (78.9 ± 1.70 and 91.97 ± 0.37 %, respectively) (P < 0.05). In vivo; after 60 min ketotifen at 2 mg/kg in 3 h before tachyzoite injection (69.83 ± 2.25 %), and cromolyn sodium, at 10 mg/kg in 6 h before tachyzoite injection (80.47 ± 2/49 %) had the best effect on inhibition of Toxoplasma entry into the cells (P < 0.05). Our findings show that ketotifen and cromolyn sodium are suitable drugs for entrance inhibition of tachyzoites into nucleated cells in vitro and in vivo. PMID:27605827

    The finding that ergotamine binds serotonin receptors in a less conserved extended binding pocket close to the extracellular entrance, in addition to the orthosteric site, allowed us to obtain 5-HT7R antagonist 6 endowed with high affinity (Ki=0.7 nM) and significant 5-HT1AR selectivity (ratio>1428). Compound 6 exhibits in vivo antidepressant-like effect (1 mg/kg, ip) mediated by the 5-HT7R, which reveals its interest as a putative research tool or pharmaceutical in depression disorders.

  8. Measuring indoor occupancy in intelligent buildings using the fusion of vision sensors

    International Nuclear Information System (INIS)

    In intelligent buildings, practical sensing systems designed to gather indoor occupancy information play an indispensable role in improving occupant comfort and energy efficiency. In this paper, we propose a novel method for occupancy measurement based on the video surveillance now widely used in buildings. In our method, we analyze occupant detection both at the entrance and inside the room. A two-stage static detector is presented based on both appearances and shapes to find the human heads in rooms, and motion-based technology is used for occupant detection at the entrance. To model the change of occupancy and combine the detection results from multiple vision sensors located at entrances and inside rooms for more accurate occupancy estimation, we propose a dynamic Bayesian network-based method. The detection results of each vision sensor play the role of evidence nodes of this network, and thus, we can estimate the true occupancy at time t using the evidence prior to (and including) time t. Experimental results demonstrate the effectiveness and efficiency of the proposed method. (paper)

  10. Calculation of entrance exposed area from recorded images in cardiac diagnostic and interventional procedures

    International Nuclear Information System (INIS)

    With increasing number of interventional radiological procedures performed on patients of all ages, it is important to determine the skin entrance dose of patients to limit the side effects of radiation. In most cases the skin dose is measured using thermoluminescent detectors (TLD). However, these detectors need to be placed in the radiation field on the skin of the patient, which may interfere with the procedure. Also, not all radiological practices are equipped with TLD readers which are expensive or have staff with the appropriate knowledge and expertise to be able to make use of TLD. The alternative to TLD is to use the dose area product (DAP) measured with a diamentor fitted to the angiography x-ray equipment. The difficulties in using DAP to calculate skin dose is that the irradiated area of the skin is not known. The area could change in size and location during the procedure as the radiologist/medical specialist varies the collimation and region of interest. For angiography equipment the distance between the anode and image intensifier is variable, as is the height of the examination table. The only point of reference is the isocentre. With recorded images it is possible to determine the irradiated area of the patient at the isocentre plane using the stenosis algorithm. The recorded image is calibrated such that it corresponds to the physical size in the plane of the isocentre. For non-recorded images, it may be necessary to assume that collimation has not changed and that the irradiated area is the same as that shown on the recorded images. The Women's and Children's Hospital has a Toshiba DFP2000 Biplane Digital Imaging system used for all cardiac and general angiography and interventional procedures. With this system the exposure factors (kVp, mA, field sizes) are recorded with the images. The source to image distance (SID), magnification factor (calibration factor of the recorded images) and angle of rotation are displayed on the Display Panel of the

    The knowledge of the radiation dose received by the patient during the radiological examination is essential to prevent risks of exposures. The aim of this work is to study patient doses for common diagnostic radiographic examinations in hospitals affiliated to Kashan University of Medical sciences, Iran. The results of this survey are compared with those published by some national and international values. Entrance surface dose (ESD) was measured based on the exposure parameters used for the actual examination and effective dose (ED) was calculated by use of conversion coefficients calculated by Monte Carlo methods. The mean entrance surface dose and effective dose for examinations of the chest (PA, Lat), abdomen (AP), pelvis (AP), lumbar spine (AP, Lat) and skull (AP, Lat) are 0.37, 0.99, 2.01, 1.76, 2.18, 5.36, 1.39 and 1.01 mGy, and 0.04, 0.1, 0.28, 0,28, 0.23, 0.13, 0.01 and 0.01 mSv, respectively. The ESDs and EDs reported in this study, except for examinations of the chest, are generally lower than comparable reference dose values published in the literature. On the basis of the results obtained in this study can conclude that use of newer equipment and use of the proper radiological parameter can significantly reduce the absorbed dose. It is recommended that radiological parameter in chest examinations be revised. PMID:26156930

  14. The effect of gel filled patient support pads on skin entrance dose, tube loading and image quality

    International Nuclear Information System (INIS)

    A range of gel filled pads designed to provide patient support and cushioning during diagnostic radiological procedures are commercially available. Several of these pads were examined with respect to their effect on diagnostic x-ray tube loading, image quality and patient skin entrance dose. For both small and larger sized patients, the pads typically increased tube loading. Tube loading increases ranged from five to 70 per cent, depending on the subject, the body part imaged, and the thickness of the pad being used. All pads tested had a minimal effect on image quality when the pads obscured the entire field of view. However, it was noticed that when the pad obscured only part of the field of view, the part covered by the pad was in some instances noticeably underexposed. The clinical effect of this was not investigated. The effect on skin entrance dose depended on pad placement. Typically, if the pad was placed between patient and image receptor the dose increased as a result of the higher exposure factors required to maintain adequate image exposure. However, if the pad was placed between the patient and tube, the added filtration of the pad served to reduce patient dose. Copyright (2001) Australian Institute of Radiography

  15. The thermal entrance region in a porous medium saturated by a nanofluid: analysis of the Brinkman's model

    International Nuclear Information System (INIS)

    The Darcy-Graetz problem for a channel filled by a nanofluid saturated porous medium is studied. The flow is assumed to be fully developed and described through Brinkman's model. For the model of the nanofluid, both thermophoresis and Brownian diffusion are taken into account. After an adiabatic preparation region, a boundary temperature linearly varying with the longitudinal coordinate is prescribed. A study of the thermal behaviour of the nanofluid is performed by solving numerically the fully-elliptic coupled equations, with reference both to the thermal entrance region and to the fully developed region. With reference to the fully developed region the solution has been obtained analytically, while for the thermal entrance region it has been obtained numerically, by a Galerkin finite element method implemented through the software package Comsol Multiphysics (© Comsol, Inc.). The analysis shows that, for physically interesting values of the Peclet number, the concentration field depends very weakly on the temperature distribution, for any given value assumed by the Darcy number. Indeed, since the effects of thermophoresis and Brownian diffusion are negligible, the homogeneous model could be employed effectively

  16. Development of a scintillating fiber-optic dosimeter for measuring the entrance surface dose in diagnostic radiology

    International Nuclear Information System (INIS)

    As a direct method, a scintillating fiber-optic dosimeter (SFOD) was fabricated using an organic scintillator, a plastic optical fiber, and a photomultiplier tube (PMT) to measure entrance surface doses (ESDs) in diagnostic radiology. In this study, we measured the scintillating lights, which are altered by to the exposure parameters, such as the tube potential, current-time product, and focus-surface distance (FSD), with an SFOD placed on the top of an acrylic and aluminum chest phantom to provide a backscatter medium. The scintillating light signals of the SFOD were compared with the ESDs obtained using conventional dosimeters. The ESDs that were measured using the dose-area product (DAP) meter, as an indirect method, and a semiconductor dosimeter, as a direct method, were distinguished according to differences in the measurement position and the method used. In the case of the two direct methods with the SFOD and the semiconductor dosimeter, the output light signals of the SFOD were similar to the ESDs of the semiconductor dosimeter. It is expected that the SFOD will be a useful dosimeter for diagnostic radiology due to its many advantages, including its small size, lightweight, substantial flexibility, remote sensing, real-time monitoring, and immunity to electromagnetic interference (EMI). - Highlights: ► Fabrication of a scintillating fiber-optic dosimeter for use in diagnostic radiology. ► Measurements of the scintillating light according to the exposure parameters. ► Comparison of the entrance surface doses obtained using conventional dosimeters

  17. Measurement of breast entrance exposure and mean glandular dose during screen-film mammography examination at our centre

    International Nuclear Information System (INIS)

    Radiation based imaging modalities have been of great benefit to mankind due to their ability to help in diagnosis. Mammography is recognized as the most optimized imaging modality for early detection of breast cancer. However there has been a growing concern among the general public, as well as the scientific and medical communities regarding the ill effect of radiation exposure from diagnostic X-ray examination. Therefore increased attention has recently been directed towards radiation dose to the patient. Several years ago the radiation dose received during mammography was measured as the entrance dose to the skin of the breast. Now, it is presumed that it is the breast glandular tissue that is at risk for developing cancer in future therefore measurement of mean glandular dose (MGD) is the quantity recommended by ICRP and European Protocol for performance assessment of the system. With optimization technique and continued quality assurance programme the breast dose can be kept at lower levels without sacrificing diagnostic value. Our objective intends to evaluate the Breast Entrance Exposure (BEE) and Mean Glandular Dose (MGD) received by the patients during mammography examination. According to the Mammography Quality Standard Act (MQSA, 2002), USA, the average glandular dose to an average (4.2 cm compressed) breast must not exceed 3 mGy per view for film-screen image receptors. The European protocol specifies the average glandular dose for a 4.5 cm thick breast typically less than 2.0 mGy

    The purpose of the study was to depict a subset of focal partial tears of the biceps brachii tendon, occurring at the entrance to the bicipital groove, which can be difficult to detect with MRI. The institutional review board approved this HIPAA-compliant study; informed consent was waived. The authors retrospectively reviewed imaging and medical records in 16 consecutive patients (12 men, 4 women; mean age, 57 years) who had prospective MRI diagnoses of tendinopathy and/or partial tearing of the intra-articular segment of the long head of the biceps brachii tendon (LHBT) at the entrance to the bicipital groove (restricted to within 1 cm of the groove entrance) and who also had surgical correlation within 4 months of imaging. Focal intrasubstance signal abnormality was noted in the tendons of 16 out of 16 (100%) patients. Focal tendon enlargement was noted in 8 out of 16 patients (50%). Fifteen out of 16 biceps partial tears (94%) were treated surgically. Shoulder pathology was restricted to the groove entrance in 4 out of 16 patients (25%). We depict a subset of focal partial tears of the biceps tendon, which can be difficult to detect on MRI because of their anatomical location at the entrance to the bicipital groove. Although they may coexist with other causes of shoulder pain, these lesions can also occur in isolation. In either case, they are potential causes of pain that can be addressed surgically. (orig.)

  7. Determining CO2-brine relative permeability and capillary pressure simultaneously: an insight to capillary entrance and end effects

    Science.gov (United States)

    Chen, X.; Kianinejad, A.; DiCarlo, D. A.

    2014-12-01

    CO2-brine relative permeability relations are important parameters in modeling scenarios such as CO2 sequestration in saline aquifers and CO2 enhanced recovery in oil reservoir. Many steady-state experimental studies on CO2-brine relative permeability showed that the CO2-brine relative permeability differs greatly from typical oil-brine relative permeability. Particularly, they reported a very small endpoint CO2 relative permeability of 0.1~0.2 at a relative high residual water saturation of 0.4~0.6. In this study, we hypothesize the measured low endpoint CO2 relative permeability in previous studies was an experimental artifact that is primary due to low CO2 viscosity. We conducted steady-state CO2 drainage experiments by co-injecting equlibrated CO2 and brine into a long (60.8 cm) and low permeability (116-mD) Berea sandstone core at 20 °C and 1500 psi. During every experiment, both the overall pressure drop across the core and the pressure drops of the five independent and continuous sections of the core were monitored. The in-situ saturation was measured with a medical X-ray Computed Tomography (CT) scanner. In the center three sections where saturation was uniform, we determined the relative permeability to both brine and CO2 phases. In the entrance and exit sections, both measured pressure gradients and saturation were non-uniform. To cope with this, we make several self-consistent assumptions that reveal the nature of capillary entrance and effect in steady-state two-phase core flooding experiments. Based on these assumptions we determined the relative permeability to CO2 and CO2-brine capillary pressure simultaneously using measured pressure drops. We found: (1) a much higher endpoint CO2 relative permeability of 0.58 at a water saturation of 48%, (2) the entrance region with non-uniform saturation expanded CO2 relative permeability data to much lower water saturation, (3) the determined CO2-brine capillary pressure curve is self-consistent and matches

  9. The neutron dose equivalent evaluation and shielding at the maze entrance of a Varian Clinac 23EX treatment room

    International Nuclear Information System (INIS)

    Purpose: To evaluate the neutron and photon dose equivalent rate (Hn,D and HG) at the outer maze entrance and the adjacent treatment console area after the installation of a Varian Clinac 23EX accelerator with a higher beam energy than its predecessor. The evaluation was based on measurements and comparison with several empirical calculations. The effectiveness of borated polyethylene (BPE) boards, as a maze wall lining material, on neutron dose and photon dose reduction is also reported. Methods: A single energy Varian 6 MV photon linear accelerator (linac) was replaced with a Varian Clinac 23EX accelerator capable of producing 18 MV photons in a vault originally designed for the former accelerator. In order to evaluate and redesign the shielding of the vault, the neutron dose equivalent Hn,D was measured using an Andersson-Braun neutron Rem meter and the photon dose equivalent HG was measured using a Geiger Mueller and an ion chamber γ-ray survey meter at the outer maze entrance. The measurement data were compared to semiempirical calculations such as the Kersey method, the modified Kersey method, and a newly proposed method by Falcao et al. Additional measurements were taken after BPE boards were installed on the maze walls as a neutron absorption lining material. Results: With the gantry head tilted close to the inner maze entrance and with the jaws closed, both neutron dose equivalent and photon dose equivalent reached their maximum. Compared to the measurement results, the Kersey method overestimates the neutron dose equivalent Hn,D by about two to four times (calculation/measurement ratio≅2.4-3.8). Falcao's method largely overestimates the Hn,D (calculation/measurement ratio≅3.9-5.5). The modified Kersey method has a calculation to measurement ratio about 0.6-0.9. The photon dose equivalent calculation including McGinley's capture gamma dose equivalent equation estimates about 77%-98% of the measurement. After applying BPE boards as a lining material on

  10. Magnetic structure in the entrance region of spheromaks sustained by a magnetized coaxial plasma gun under long pulse operation

    International Nuclear Information System (INIS)

    The magnetic structure in coaxial-gun-sustained spheromaks has been investigated. The plasma gun has been operated with a small axial/radial bias magnetic flux as compared to the azimuthal magnetic flux produced by the discharge current. Stronger magnetic field is observed in the entrance region (ER) than in the flux conserver (FC). In both ER and FC, the magnetic structure is nearly axisymmetric. The axial magnetic field in ER is amplified up to about sixteen times as large as the bias magnetic field. This amplification is limited by the drastic change in the magnetic structure, which occurs when the discharge current becomes very large. The magnetic structure before the drastic change is interpreted with the Bessel function model. The μ estimation shows that the magnetic structure is mainly determined by the boundary geometry, not by the external magnetic flux and current. (author)

    The entrance channel dependence of the isospin effects of nuclear stopping in intermediate energy heavy-ion collisions has been studied by using an isospin-dependent quantum molecular dynamics with three different kinds of symmetry potentials. It is shown that nuclear stopping is sensitive to the beam energy, the impact parameter and the mass of the colliding system, especially very sensitive to the isospin dependence of the in-medium nucleonnucleon cross section, but insensitive to the symmetry potential and the neutron-to-proton ratio of the colliding system. From this investigation, it is proposed that nuclear stopping can be used as a new probe to extract the information on the isospin dependence of the in-medium nucleon-nucleon cross section in intermediate energy heavy-ion collisions.

    Full Text Available A building code, or building control, is a set of rules that specify the minimum standards for constructed objects such as buildings and non building structures. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants and others.

  14. Sustainable Buildings in Interaction

    Elle, Morten

    The first attempts to build sustainable buildings in Denmark were typically located on the countryside. The basic idea was to create buildings that were independent of the technical infrastructure. District heating has, however, been the dominating solution to heating in buildings in Denmark, and...... the focus on sustainable building have gradually turned from special houses on the countryside to normally looking houses in the urban fabric, integrated in the technical infrastructure. Some new built urban areas in Denmark will, however, not have to be supplied with district heating – these...... developments are going to consist of passive houses. The first sustainable buildings were built by their users, and the user – building interaction still play a decisive role for the performance of the present sustainable buildings. The users have to understand how the building functions. Urban design is...

    Full Text Available Subject of Research.Oxide films on the metal surfaces can be obtained both by surface-uniform infrared heating and local laser treatment e.g. by sequence of nanosecond laser pulses. Due to interference in created films the coloration of treated area is observed. The present work shows the results of spectrophotometric measurements for various light entrance angles in the range of 10-60°. Method. AISI 304 stainless steel plates were oxidized by two methods: in muffle furnace FM - 10 (Т= 500-600° С, t = 5-7 min. and at line-by-line scanning by sequence of nanosecond laser pulses (λ = 1.06 μm, τ =100 ns, r = 25 μm,q=2.91∙107 W/cm2, Nx = 30, Ny = 1. Surface research in optical resolution was realized by Carl Zeiss Axio Imager A1M. Reflectance spectra were obtained with spectrophotometer Lambda Perkin 1050 with integrating sphere at different fixed light incidence angles. Topographic features were detected by scanning probe microscopy investigation with NanoEducator equipment. Main Results. The quantitative surface geometry characteristics of AISI 304 stainless steel patterns treated by different methods are obtained. It was found that the increase of light entrance angle has no influence on the form of reflection coefficient dependence from a wavelength, but a blue-shift occurs especially for the case of laser treatment. This difference can be caused by surface topology formed by laser heating and variety of oxide film thickness. This effect results in more significant change in observed sample color for laser treatment then for infrared heating. Practical Relevance. The results obtained in the present work can be used to implement a new element of product protection against forgery with the product marking.

  16. Computational and experimental studies of the flow field near the beam entrance window of a liquid metal target

    International Nuclear Information System (INIS)

    Highlights: • Water model of liquid metal target for validation of CFD models was built. • PIV measurements showed flow features in the region near beam entrance window. • The zones with high turbulence kinetic energy were distinguished. • Reasonable agreement between modeling and PIV data was obtained. - Abstract: After the first world liquid metal target has been successfully operated at the SINQ facility at the Paul Scherrer Institut (PSI) for 6 months. The idea of having a reliable target with a bypass flow for cooling the beam entrance window, but with the bypass flow not driven by a separate pump, was examined within the project called LIMETS (Liquid Metal Target for SINQ). In designing of liquid metal targets, turbulence modelling is of high importance due to lack in methods for measuring the spatial distribution of flow and turbulence characteristics. In this study, validation of different turbulence models were performed in water model with hemispherical geometry using particle image velocimetry (PIV) technique. Two components of water flow velocity in plexiglas container with inner radius of 88 mm were measured in different cross sections, with the velocities varying from 1 to 10 m/s. Numerical calculations using large eddy simulation (LES) approach and Reynolds averaged Navier–Stokes (RANS) models were carried out to validate their applicability and study performance issues. Mean velocity and turbulence kinetic energy data were used for comparison of PIV and calculation results. Reasonable agreement was obtained for mean velocity data, with some discrepancies due to the limited length of the inlet tube. However, several discrepancies in turbulence characteristics were found in numerical results, especially in RANS model calculations

  17. Experimental and numerical investigation of an entrance blockage of an inner channel in dual-cooled annular nuclear fuel

    International Nuclear Information System (INIS)

    A dual-cooled annular nuclear fuel for a Pressurized Water Reactor (PWR) has been introduced for a significant increase in reactor power. The Korea Atomic Energy Research Institute (KAERI) has been researching the development of a dual-cooled annular fuel for a power increase in an optimized PWR in Korea, OPR-1000. The main advantage of a dual-cooled annular fuel is an increased heat transfer area and a reduction in the fuel temperature, which would result in reduced fission gas release and increased fuel melting margin and Departure from Nucleate Boiling (DNB) margin. The annular fuel rod is configured to allow the coolant flow through the inner channel as well as outer channel. Since the inner channel is isolated from the neighbor channels unlike the outer channels, an inner channel blockage is one of the principal technical issues of a dual-cooled annular fuel. Due to a partial blockage, the inner channel may be faced with a DNB accident. A conceptual design used to complement the entrance blockage of an inner channel was suggested by KAERI. The through holes in this design are formed on a cylindrical wall of the lower end plug. When the inner channel is blocked by debris, coolant for the inner channel will be supplied through the side holes. But due to very unusual shape of the lower end plug, it is difficult to estimate the flow resistance of the side flow holes using empirical correlations available in the open literatures. Experimental and Computational Fluid Dynamics (CFD) studies were performed to investigate the bypass flow through the side holes of the lower end plug to complement the entrance blockage of an inner channel. The form loss coefficient in the side holes was also estimated by using the pressure drop along the bypass flow path and DNB Ratio (DNBR) margin was estimated by a subchannel analysis code. (author)

    Coronary angiography is a procedure used in the diagnosis and intervention of coronary heart disease. The procedure is often considered one of the highest dose diagnostic procedures in clinical use. Despite this, there is minimal use of dosimeters within angiographic catheterisation laboratories due to challenges resulting from their implementation. The aim of this study was to compare entrance dose delivery across locally commissioned c-arms to assess the need for real-time dosimetry solutions during angiographic procedures. The secondary aim of this study was to establish a calibration method for the MOSkin dosimeter that accurately produces entrance dose values from the clinically sampled beam qualities and energies. The MOSkin is a real-time dosimeter used to measure the skin dose delivered by external radiation beams. The suitability of the MOSkin for measurements in the angiographic catheterisation laboratory was assessed. Measurements were performed using a 30 × 30 × 30 cm(3) PMMA phantom positioned at the rotational isocenter of the c-arm gantry. The MOSkin calibration factor was established through comparison of the MOSkin response to EBT2 film response. Irradiation of the dosimeters was performed using several clinical beam qualities ranging in energy from 70 to 105 kVp. A total of four different interventional c-arm machines were surveyed and compared using the MOSkin dosimeter. The phantom was irradiated from a normal angle of incidence using clinically relevant protocols, field sizes and source to image detector distance values. The MOSkin was observed to be radiotranslucent to the c-arm beam in all clinical environments. The MOSkin response was reproducible to within 2 % of the average value across repeated measurements for each beam setting. There were large variations in entrance dose delivery to the phantom between the different c-arm machines with the highest observed cine-acquisition entrance dose rate measuring 326 % higher than the

    Buildings are an integral part of our nation’s energy economy. The advancement in information and communications technology (ICT) has revolutionized energy management in industrial facilities and large commercial buildings. As ICT costs decrease and capabilities increase, buildings automation and energy management features are transforming the small-medium commercial and residential buildings sectors. A vision of a connected world in which equipment and systems within buildings coordinate with each other to efficiently meet their owners’ and occupants’ needs, and where buildings regularly transact business with other buildings and service providers (such as gas and electric service providers) is emerging. However, while the technology to support this collaboration has been demonstrated at various degrees of maturity, the integration frameworks and ecosystems of products that support the ability to easily install, maintain, and evolve building systems and their equipment components are struggling to nurture the fledging business propositions of their proponents.

  14. Neutron transport in a clinical linear accelerator bunker: comparison of materials for reducing the photo-neutron dose at the maze entrance

    International Nuclear Information System (INIS)

    Megavoltage photons above 10 MeV used in external beam radiotherapy lead to a significant photoneutron fluence, which must be taken into account in bunker design. This work describes Monte-Carlo simulations of such neutrons for a proposed bunker which is to house a 15 MV accelerator. Of particular interest was the effect on the neutron dose at the maze entrance, of cladding maze walls with various materials. Simulations were performed using the MCNP4B Monte-Carlo code. Mean photo-neutron energies of 0.5, 3 and 6 MeV were assumed to be produced isotropically from the accelerator head. Neutron fluence spectra and absorbed dose due to neutrons and neutron-capture photons were scored at the machine isocentre and at the maze entrance in a 30 cm diameter sphere of tissue. Absorbed dose at the maze entrance was then determined relative to isocentre dose. The reduction in neutron dose at the maze entrance, achieved by cladding concrete maze walls with either wood, polystyrene or a commercially available plastic, was determined. A comparison of materials has been made in terms of efficiency and cost implications. (author)

    2005-04-01

    For many years, building design has been a very linear process with owners speaking to architects who then design building shells that they pass along to sub-consultants who must fit their systems into the allotted spaces. While this process has some advantages, it provides little opportunity to optimize systems based on such factors as energy use or occupant comfort. This presentation will focus on the evolution and implications of integrated building design, a method that has provided greater opportunities for interaction between design disciplines and with building users early on in the design process. Integration has resulted in buildings that are more sustainable than typical buildings and that can respond better to the needs of the owner and users. Examples of the application of the process and the resulting buildings will be presented from the view of a design engineer with experience of both processes. Specifically, the potential contribution of an acoustical consultant in the integrated process will be explored.

    Commercial Buildings Characteristics 1992 presents statistics about the number, type, and size of commercial buildings in the United States as well as their energy-related characteristics. These data are collected in the Commercial Buildings Energy Consumption Survey (CBECS), a national survey of buildings in the commercial sector. The 1992 CBECS is the fifth in a series conducted since 1979 by the Energy Information Administration. Approximately 6,600 commercial buildings were surveyed, representing the characteristics and energy consumption of 4.8 million commercial buildings and 67.9 billion square feet of commercial floorspace nationwide. Overall, the amount of commercial floorspace in the United States increased an average of 2.4 percent annually between 1989 and 1992, while the number of commercial buildings increased an average of 2.0 percent annually.

  5. Building for animal production

    International Nuclear Information System (INIS)

    In order to limit the radiation dose to persons working with animal husbandry in severe fallout situations, it was considered necessary to make an inventory of the Swedish livestock buildings as to number, location, use and size. These data as well as data on geometry of buildings, building material and thickness of the material in walls and roofs are given in the present work. On the basis of the mentioned data, calculations were made of the shielding factors of different types of livestock buildings. The collected data can also be used in preparedness planning in relation to housing facilities for livestock and location and size of animal production in situations of crises or war. The calculations show shielding factors for different types of livestock buildings of normal ground area within the range of 0.18-0.71. The higher value indicates a fairly poor shielding effect. The inventory and the calculations show that in those regions in Sweden where the main part of the livestock is managed, the types of buildings are, however, characterized by radiation shielding factors of 0.3-0.4. Calculation were also made of the radiation level inside the buildings following decontamination of roofs or of surrounding ground. Ground decontamination only, i.e., removal of the upper contaminated surface layer, will reduce the radiation level inside the building. For most buildings the radius of the surrounding area to be decontaminated has to be 15-30 times larger than the width of the building in order to achieve a 50 percentage reduction of the radiation level inside the building. For buildings of medium or large size and with thick walls the radiation contribution from the roof is greater than the radiation from the ground, and regardless of the size of the ground areas decontaminated the radiation level inside these buildings will only be reduced by 20-30%. 15 refs, 11 figs, 14 tabs

    Full Text Available A miniature fiber-optic dosimeter (FOD system was fabricated using a plastic scintillating fiber, a plastic optical fiber, and a multi-pixel photon counter to measure real-time entrance surface dose (ESD during radiation diagnosis. Under varying exposure parameters of a digital radiography (DR system, we measured the scintillating light related to the ESD using the sensing probe of the FOD, which was placed at the center of the beam field on an anthropomorphic thorax phantom. Also, we obtained DR images using a flat panel detector of the DR system to evaluate the effects of the dosimeter on image artifacts during posteroanterior (PA chest radiography. From the experimental results, the scintillation output signals of the FOD were similar to the ESDs including backscatter simultaneously obtained using a semiconductor dosimeter. We demonstrated that the proposed miniature FOD can be used to measure real-time ESDs with minimization of DR image artifacts in the X-ray energy range of diagnostic radiology.

    The potential submarine geologic hazards were distinguished and categorized at the entrance of the Pearl River Estuary in the northern South China Sea, based upon the analysis of side scan sonar and sub-bottom profiler surveying data of about 2500 km long, in an area about 2000 km2 around the Wanshan Archipelago. The data obtained in the survey has the highest spatial resolution by far, which could reveal more detailed distributions and characteristics of the geologic hazards than before. In the study region, three paleo-channels that were buried about 10-30 m below the seabed were found; more than 10 shallow gas areas were discovered. The sand waves found in the region were generally small and located near the islands, and twenty pockmarks found on the seabed were mostly concentrated to north of Zhuzhou island. There are also many man-made obstacles in the region, such as wreckages, pipeline, etc. In this paper we provide a detailed distribution map of the submarine geologic hazards in this region for the first time, and discuss their formation and harmfulness, which will provide a scientific basis for marine engineering construction, marine geologic disaster prevention and mitigation.

    Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul-the random assignment of students into single-sex versus coeducational high schools-to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. The three-level hierarchical model shows that attending all-boys schools or all-girls schools, rather than coeducational schools, is significantly associated with higher average scores on Korean and English test scores. Applying the school district fixed-effects models, we find that single-sex schools produce a higher percentage of graduates who attended four-year colleges and a lower percentage of graduates who attended two-year junior colleges than do coeducational schools. The positive effects of single-sex schools remain substantial, even after we take into account various school-level variables, such as teacher quality, the student-teacher ratio, the proportion of students receiving lunch support, and whether the schools are public or private.

    The evaporation residue yields from compound nuclei $^{220}$Th formed in the $^{16}$O+$^{204}$Pb, $^{40}$Ar+$^{180}$Hf, $^{82}$Se+$^{138}$Ba, $^{124}$Sn+$^{96}$Zr reactions are analyzed to study the entrance channel effects by comparison of the capture, fusion and evaporation residue cross sections calculated by the combined dinuclear system (DNS) and advanced statistical models. The difference between evaporation residue (ER) cross sections can be related to the stages of compound nucleus formation or/and at its surviving against fission. The sensitivity of the both stages in the evolution of DNS up to the evaporation residue formation to the angular momentum of DNS is studied. The difference between fusion excitation functions are explained by the hindrance to complete fusion due to the larger intrinsic fusion barrier $B^*_{\\rm fus}$ for the transformation of the DNS into a compound nucleus and the increase of the quasifission contribution due to the decreasing of quasifission barrier $B_{\\rm qf}$ as a func...

    Full Text Available The washback effect of high-stakes tests has been explored in different countries and various educational contexts. Washback generally refers to the influence of testing on teaching and learning (Alderson & Wall, 1993. This paper which is a part of a larger study seeks to report the perceptions and attitudes of Iranian pre-university English teachers towards the effect of Iranian National University Entrance Exam (hereafter the INUEE on teachers’ English teaching and learners’ English learning. The participants were 6 female pre-university English teachers from two pre-university schools in the city of Ahwaz, Iran. To investigate their perceptions and attitudes towards the INUEE, a validated questionnaire was administered to the teachers and a semi-structured interview was also conducted in order to gain richer information, and to shed more light on the data collected through their questionnaires. The respondents answered questions on whether the test motivated the students to learn English, whether the INUEE evaluated students’ academic knowledge, etc. The descriptive and qualitative analysis of the data revealed that teachers’ perceptions towards the test were mixed. Two teachers held positive views about the test and four other teachers held negative perceptions about this high-stakes test. The findings of this study could be pedagogically significant to policy-makers, test designers, teachers, and students.

    Honey bees have crucial role in pollination across the world. This paper presents a simple, non-invasive, system for pollen bearing honey bee detection in surveillance video obtained at the entrance of a hive. The proposed system can be used as a part of a more complex system for tracking and counting of honey bees with remote pollination monitoring as a final goal. The proposed method is executed in real time on embedded systems co-located with a hive. Background subtraction, color segmentation and morphology methods are used for segmentation of honey bees. Classification in two classes, pollen bearing honey bees and honey bees that do not have pollen load, is performed using nearest mean classifier, with a simple descriptor consisting of color variance and eccentricity features. On in-house data set we achieved correct classification rate of 88.7% with 50 training images per class. We show that the obtained classification results are not far behind from the results of state-of-the-art image classification methods. That favors the proposed method, particularly having in mind that real time video transmission to remote high performance computing workstation is still an issue, and transfer of obtained parameters of pollination process is much easier.

    Sterling, T D; Collett, C; Rumel, D

    1991-02-01

    The indoor environment of modern buildings, especially those designed for commercial and administrative purposes, constitutes a unique ecological niche with its own biochemical environment, fauna and flora. Sophisticated construction methods and the new materials and machinery required to maintain the indoor environment of these enclosed structures produce a large number of chemical by-products and permit the growth of many different microorganisms. Because modern office buildings are sealed, the regulation of humidification and temperature of ducted air presents a dilemma, since difference species of microorganisms flourish at different combinations of humidity and temperature. If the indoor environment of modern office buildings is not properly maintained, the environment may become harmful to its occupants' health. Such buildings are classified as "Sick Buildings". A review of the epidemiology of building illness is presented. The etiology of occupant illnesses, sources of toxic substances, and possible methods of maintaining a safe indoor environment are described. PMID:1784964

    Full Text Available Sick building syndrome describes a number of mostly unspesific complaints of some occupants of the building. The exact pathophysiological mechanism remains elusive. It is a multi factorial event which may include physical, chemical, biological as well as psycological factors. In many cases it is due to insufficient maintenance of the HVAC (heating, ventilation, air conditioning system in the building. Sign and symptoms can be uncomfortable and even disabling, which may include mucus membrane irritation, neurotoxic symptoms, asthma like symptoms, skin complaints, gastrointestinal symptoms and other related symptoms. There are various investigation methods to diagnose sick building syndrome, and on site assessment of the building is extremely useful. Prevention through a proactive air quality monitoring program is far more desirable than dealing with an actual sick building. Indoor air and the sick building symdrome serves as a paradigm of modern occupational and environmental medicine.

  5. Neutron transport in a clinical linear accelerator bunker: comparison of materials for reducing the photo-neutron dose at the maze entrance

    International Nuclear Information System (INIS)

    Megavoltage photons above 10 MeV used in external beam radiotherapy lead to a significant photo-neutron fluence, which must be taken into account in bunker design (IPEM, 1997, Report 75, The design of radiotherapy treatment room facilities). This work describes Monte-Carlo simulations of such neutrons for a proposed bunker, which is to house a 15 MV accelerator. Neutron fluence spectra and absorbed dose due to neutrons and neutron-capture photons were scored at the accelerator iso centre and at the maze entrance for mono-energetic neutron sources of 0.5, 3 and 6 MeV. The reduction in neutron and photon dose at the maze entrance, achieved by cladding concrete maze walls with either wood, polyethylene or a commercially available plastic, was determined.

  5. Optimization of beam filtering, kV-mA regulation curve, and image intensifier entrance exposure rate to reduce radiation exposure in angiographic fluoroscopy

    International Nuclear Information System (INIS)

    Aim of study: Evaluation of radiation exposure and image quality during fluoroscopy using a new vascular X-ray system. Material and methods: The measurements were made on an Integris V 3000 X-ray system with MRC tube and SpectraBeam technology (Philips Medical Systems, Hamburg). Entrance dose rates were measured with phantoms for the three fluoroscopy levels (1-3) which differed with regard to beam filtering and image intensiver entrance exposure rate. We evaluated 132 diagnostic and interventional angiographic studies. The angiographic investigators were asked to start with level 1 and to change to the next fluoroscopy level only in the case of insufficient image quality. Results: Entrance dose rate is reduced by approx. 74% at fluoroscopy level 1 and by approx. 46% at level 2 relative to level 3 which is comparable to angiographic X-ray systems without MRC tube and SpectraBeam technology. Because level 1 ensured a sufficient image quality in 92% of the diagnostic and 60% of the interventional angiographic procedures a change to higher fluoroscopy levels was not necessary. Conclusion: Reduction of the intensifier exposure rate and the optimization of beam filtering enabled us to reduce the radiation exposure considerably. The procedure was well accepted by the angiographic investigators due to the diagnostically sufficient image quality of the fluoroscopy level 1. (orig.)

    Firearms can cause fatal wounds, which can be identified by traces on or around the body. However, there are cases where neither the bullet nor gun is found at the crime scene. Ballistic research involving finite element models can reproduce computational biomechanical conditions, without compromising bioethics, as they involve no direct tests on animals or humans. This study aims to compare the morphologies of gunshot entrance holes caused by.40-caliber Smith & Wesson (S&W), .380-caliber, and 9×19-mm Luger bullets. A fully metal-jacketed.40 S&W projectile, a fully metal-jacketed.380 projectile, and a fully metal-jacketed 9×19-mm Luger projectile were computationally fired at the glabellar region of the finite element model from a distance of 10 cm, at perpendicular incidence. The results show different morphologies in the entrance holes produced by the three bullets, using the same skull at the same shot distance. The results and traits of the entrance holes are discussed. Finite element models allow feasible computational ballistic research, which may be useful to forensic experts when comparing and analyzing data related to gunshot wounds in the forehead.

  7. Calculation of the uncertainty associated to the result of entrance surface air kerma for conventional radiology patients

    International Nuclear Information System (INIS)

    Radiation doses from diagnostic radiology are the largest contribution to the collective dose and the use of guidance (reference levels) has proven to be a tool for optimization of protection. Recently, with the support of the International Atomic Energy Agency (IAEA), eight countries of the Latin-American region have been working together on a programme to test methodologies for determining preliminary values of guidance levels for X-ray chest, lumbar spine and breast examinations. The approach used was to obtain entrance surface air kerma from measurements of X-ray tube outputs, corrected for distance and backscatter and later for real exposure parameters used with patients. For quality control, some of these values for a reduced number of patients were compared with direct TLD measurements directly placed on the patient during exposure. Given the number of parameters involved in the two methods, relatively large differences are deemed to be found in the comparison. The only way of deciding if measurements and calculations are outliers, for example, due to a systematic error or a mistake, is to compare these differences with the combined uncertainty. The aim of this paper is to present (in a detailed way) the methodology used in the pilot program ARCAL LXXV, the analyses of data performed within the survey and the estimated uncertainty. The parameters analyzed were: precision of the readings, positioning of the detector, reproducibility of the mAs and kV, long term stability of the instrument, radiation quality, kerma rate, radiation incidence, field size and field homogeneity, calibration factor of the equipment, temperature and pressure measurement, X-ray tube output curve adjustment, backscatter factor and focus-patient distance. The combined standard uncertainty for Ke in chest radiography in adult patients of standard complexion, was 12%, and the expanded uncertainty (k=2) was 24%. (author)

  8. Using laser entrance hole shields to increase coupling efficiency in indirect drive ignition targets for the National Ignition Facility

    International Nuclear Information System (INIS)

    Coupling efficiency, the ratio of the capsule absorbed energy to the driver energy, is a key parameter in ignition target designs. The hohlraum originally proposed for the National Ignition Facility (NIF) [G. H. Miller, E. I. Moses, and C. R. Wuest, Nucl. Fusion 44, S228 (2004)] coupled ∼11% of the absorbed laser energy to the capsule as x rays. Described here is a second generation of the hohlraum target which has a higher coupling efficiency, ∼16%. Because the ignition capsule's ability to withstand three-dimensional effects increases rapidly with absorbed energy, the additional energy can significantly increase the likelihood of ignition. The new target includes laser entrance hole (LEH) shields as a principal method for increasing coupling efficiency while controlling symmetry in indirect-drive inertial confinement fusion. The LEH shields are high Z disks placed inside the hohlraum on the symmetry axis to block the capsule's view of the relatively cold LEHs. The LEH shields can reduce the amount of laser energy required to drive a target to a given temperature via two mechanisms: (1) keeping the temperature high near the capsule pole by putting a barrier between the capsule and the pole; (2) because the capsule pole does not have a view of the cold LEHs, good symmetry requires a shorter hohlraum with less wall area. Current integrated simulations of this class of target couple 140 kJ of x rays to a capsule out of 865 kJ of absorbed laser energy and produce 10 MJ of yield. In the current designs, which continue to be optimized, the addition of the LEH shields saves ∼95 kJ of energy (about 10%) over hohlraums without LEH shields

    The development of novel NNRTIs with activity against variants of HIV-1RT is crucial for overcoming treatment failure. In the present study, a series of novel 6-substituted diarylpyridine derivatives targeting the entrance channel of the NNIBP of RT were designed through a molecular hybridization strategy. Encouragingly, these new diarylpyridine derivatives were found to be active against wild-type (WT) HIV-1 with an EC50 values ranging from 0.035 μM to 1.99 μM. Nearly half of them exhibited more potent inhibitory activities in cellular assays than the control drug nevirapine (NVP). Notably, three most promising compounds If (EC50 = 35 nM), Ia (EC50 = 43 nM) and IIa (EC50 = 41 nM) showed high potency against WT and were comparable to the reference drug delavirdine (DLV) (EC50 = 33 nM). Moreover, compounds Ib, IIb and IIh displayed effective activity against the most common clinically observed single and double-mutated HIV-1 strains in micromolar concentrations. In particular, the inhibition of IIb against the K103N mutation (EC50 = 49 nM), which confers resistance to a wide variety of NNRTIs, was about 140 times more effective than NVP (EC50 = 6.78 μM), 50 times more than DLV (EC50 = 2.48 μM) and about 3 times more than EFV (EC50 = 0.12 μM), indicating that the newly designed compounds have great potential to be further developed as new anti-HIV-1 agents. Preliminary structure-activity relationships (SARs) and molecular modeling of the new diarylpyridine derivatives were discussed in detail. PMID:26802545

    Measuring the x-ray flux exiting the target's laser entrance hole (LEH) is the most common diagnostic that quantifies the x-ray intensity inside the laser-driven hohlraum. However, this signal accounts for only a small portion of the incident laser power and thus is likely to be affected by unwanted x-ray background from non-target area, leading to an overestimation of the hohlraum drive. Unwanted emission might be produced when the laser light is clipped by the LEH (LEH clipping) because of a lack of clearance for laser spot, or with a laser spot comprising of discrete structure, or even with a poor pointing accuracy. Its influence on the hohlraum radiation diagnostic is investigated on Shenguang-III prototype laser facility with the typical 1 ns square pulse. The experiment employed three types of targets to excite the unwanted x-ray background from LEH clipping, unconverted light, and both effects, respectively. This work gives an absolute evaluation of x-ray produced by the LEH clipping, which is measured by flat-response x-ray detectors (FXRD) at multiple view angles. The result indicates that there is little variation in measured emission to various view angles, because the unwanted x-rays are mainly generated at the side face of the LEH lip when laser is obliquely incident. Therefore, the LEH clipping brings more overestimation in hohlraum radiation measurement at larger view angle since the hohlraum LEH as an emitting source viewed by FXRD is decreased as the view angle increases. In our condition, the LEH clipping contributes 2%–3.5% overestimation to the hohlraum flux measurement.

    This paper is a presentation of an 'instrument' for the optimization of the functionality and conservation of tertiary buildings. This technique has several different names: Building Automation Systems (BAS), Central Control and Monitoring System (CCMS) in English, and Gestion Technique du Bâtiment' (GTB) or Gestion Technique Centralisée (GTC) in French. With this technique it is possible to manage all the functions of a building, it is a modern instrument that introduces the concept of 'automation' in the operation of buildings using computerized procedures, earlier reserved for industrial processes. The system is structured with different automation levels with a distributed intelligence, each level characterized by a communication system (Fieldbus for the lowest and Ethernet for the highest level). In order to apply the BAS to CERN buildings it is necessary to evaluate the advantages, the CERN requirements and the integration with the several existing control and automation systems.

    Siek, Michael; Solomatine, Dimitri

    2010-05-01

    This paper presents a number of novel techniques for building a predictive chaotic model from incomplete time series. A predictive chaotic model is built by reconstructing the time-delayed phase space from observed time series and the prediction is made by a global model or adaptive local models based on the dynamical neighbors found in the reconstructed phase space. In general, the building of any data-driven models depends on the completeness and quality of the data itself. However, the completeness of the data availability can not always be guaranteed since the measurement or data transmission is intermittently not working properly due to some reasons. We propose two main solutions dealing with incomplete time series: using imputing and non-imputing methods. For imputing methods, we utilized the interpolation methods (weighted sum of linear interpolations, Bayesian principle component analysis and cubic spline interpolation) and predictive models (neural network, kernel machine, chaotic model) for estimating the missing values. After imputing the missing values, the phase space reconstruction and chaotic model prediction are executed as a standard procedure. For non-imputing methods, we reconstructed the time-delayed phase space from observed time series with missing values. This reconstruction results in non-continuous trajectories. However, the local model prediction can still be made from the other dynamical neighbors reconstructed from non-missing values. We implemented and tested these methods to construct a chaotic model for predicting storm surges at Hoek van Holland as the entrance of Rotterdam Port. The hourly surge time series is available for duration of 1990-1996. For measuring the performance of the proposed methods, a synthetic time series with missing values generated by a particular random variable to the original (complete) time series is utilized. There exist two main performance measures used in this work: (1) error measures between the actual

    Full Text Available Although social, economic, and cultural indicators are of substantial importance to the concept of sustainable building, this concept is usually related to environmental characteristics. Any building level assessment method is complex and involves contradictory aspects. Moreover, emphasizing qualitative criteria only increases confusion. R&D and standardization are thus concentrated to transparency and usability of the environmental methods. Other directions of research aim at performance-based design and methods to take regional and cultural aspects into account. In this paper, the perspectives of the sustainability assessment of a whole building are presented, based on a state of the art, feasibility study on performance analysis and the development of an extended life-cycle assessment for buildings. Using various tools, and based on the case studies of building sustainability assessment, environmental indicators were often shown to be of lesser importance than the other, soft ones. The first steps in the development of a building sustainability assessment method for Portuguese residential buildings will be presented and discussed in the end.

    This is a study of the issues and opportunities for building-integrated PV products, seen primarily from the perspective of the design community. Although some quantitative analysis is included, and limited interviews are used, the essence of the study is qualitative and subjective. It is intended as an aid to policy makers and members of the technical community in planning and setting priorities for further study and product development. It is important to remember that the success of a product in the building market is not only dependent upon its economic value; the diverse group of building owners, managers, regulators, designers, tenants and users must also find it practical, aesthetically appealing and safe. The report is divided into 11 sections. A discussion of technical and planning considerations is followed by illustrative diagrams of different wall and roof assemblies representing a range of possible PV-integration schemes. Following the diagrams, several of these assemblies are then applied to a conceptual test building which is analyzed for PV performance. Finally, a discussion of mechanical/electrical building products incorporating PVs is followed by a brief surveys of cost issues, market potential and code implications. The scope of this report is such that most of the discussion does not go beyond stating the questions. A more detailed analysis will be necessary to establish the true costs and benefits PVs may provide to buildings, taking into account PV power revenue, construction costs, and hidden costs and benefits to building utility and marketability.

    Through its Building Technologies Office (BTO), the United States Department of Energy’s Office of Energy Efficiency and Renewable Energy (DOE-EERE) is sponsoring an effort to advance interoperability for the integration of intelligent buildings equipment and automation systems, understanding the importance of integration frameworks and product ecosystems to this cause. This is important to BTO’s mission to enhance energy efficiency and save energy for economic and environmental purposes. For connected buildings ecosystems of products and services from various manufacturers to flourish, the ICT aspects of the equipment need to integrate and operate simply and reliably. Within the concepts of interoperability lie the specification, development, and certification of equipment with standards-based interfaces that connect and work. Beyond this, a healthy community of stakeholders that contribute to and use interoperability work products must be developed. On May 1, 2014, the DOE convened a technical meeting to take stock of the current state of interoperability of connected equipment and systems in buildings. Several insights from that meeting helped facilitate a draft description of the landscape of interoperability for connected buildings, which focuses mainly on small and medium commercial buildings. This document revises the February 2015 landscape document to address reviewer comments, incorporate important insights from the Buildings Interoperability Vision technical meeting, and capture thoughts from that meeting about the topics to be addressed in a buildings interoperability vision. In particular, greater attention is paid to the state of information modeling in buildings and the great potential for near-term benefits in this area from progress and community alignment.

    2005-05-01

    Green buildings, also known as sustainable buildings, resource efficient buildings, and high performance buildings, are structures that minimize the impact on the environment by using less energy and water, reducing solid waste and pollutants, and limiting the depletion of natural resources. As Idaho National Laboratory (INL) becomes the nation’s premier nuclear energy research laboratory, the physical infrastructure will be established to help accomplish the mission. This infrastructure, particularly the buildings, should incorporate green design features in order to be environmentally responsible and reflect an image of progressiveness and innovation to the public and prospective employees. With this in mind, the recommendations described in this strategy are intended to form the INL foundation for green building standards. The recommendations in this strategy are broken down into three levels: Baseline Minimum, Leadership in Energy and Environmental Design (LEED)Certification, and Innovative. Baseline Minimum features should be included in all new occupied buildings no matter what the purpose or size. These features do not require significant research, design, or capital costs and yet they can reduce Operation and Maintenance (O&M) costs and produce more environmentally friendly buildings. LEED Certification features are more aggressive than the Baseline Minimums in that they require documentation, studies, and/or additional funding. Combined with the Baseline Minimums, many of the features in this level will need to be implemented to achieve the goal of LEED certification. LEED Silver certification should be the minimum goal for all new buildings (including office buildings, laboratories, cafeterias, and visitor centers) greater than 25,000 square feet or a total cost of $10 million. Innovative features can also contribute to LEED certification, but are less mainstream than those listed in the previous two levels. These features are identified as areas where

  12. The size and structure of the laser entrance hole in gas-filled hohlraums at the National Ignition Facility

    International Nuclear Information System (INIS)

    At the National Ignition Facility, a thermal X-ray drive is created by laser energy from 192 beams heating the inside walls of a gold cylinder called a “hohlraum.” The x-ray drive heats and implodes a fuel capsule. The laser beams enter the hohlraum via laser entrance holes (LEHs) at each end.

The x-ray drive on the capsule is deduced by measuring the time evolution and spectra of the x-radiation coming out of the LEH and correcting for geometry and for the radius of the LEH. Previously, the LEH radius was measured using time-integrated images in an x-ray band of 3–5 keV (outside the thermal x-ray region).

The LEH radius at peak power is larger than that predicted by the models by about 15%–20% and does not change very much with time. In addition, time-resolved images in a >4 keV (non-thermal) x-ray band show a ring of hot, optically thin gold plasma just inside the optically thick LEH plasma.

    At the National Ignition Facility, a thermal X-ray drive is created by laser energy from 192 beams heating the inside walls of a gold cylinder called a “hohlraum.” The x-ray drive heats and implodes a fuel capsule. The laser beams enter the hohlraum via laser entrance holes (LEHs) at each end. The LEH radius decreases as heated plasma from the LEH material blows radially inward but this is largely balanced by hot plasma from the high-intensity region in the center of the LEH pushing radially outward.

    2013-09-01

    Full Text Available Seasonality in surface weather results in seasonal temperature and humidity changes in caves. Ecological and physiological differences among trogloxenes, troglophiles, and troglobionts result in species-dependent responses to this variability. To investigate these responses, we conducted five biological inventories in a marble cave in the Sierra Nevada Range, California, USA between May and December 2010. The cave was divided into six quadrats and temperature was continuously logged in each (humidity was logged at the entrance and in the deep cave. With increasing distance from the entrance, temperature changes were increasingly attenuated and lagged relative to surface temperature. Linear regressions were created to determine the relationship between measured environmental variables and diversity for cavernicoles (troglobionts and troglophiles and trogloxenes cave– wide and in the transition zone. Diversity for cavernicoles and trogloxenes peaked in the entrance and deep cave zones, respectively. Quadrat, date, 2-week antecedent temperature average, 2-week antecedent temperature range, and trogloxene abundance explained 76% of cavernicole diversity variability. Quadrat explained 55% of trogloxene diversity variability. In the transition zone, trogloxene abundance explained 26% of cavernicole variability and 2-week antecedent temperature and 2-week antecedent temperature range explained 40% of trogloxene variability. In the transition zone, trogloxene diversity was inversely related to 2-week antecedent temperature average and 2-week antecedent temperature range, suggesting that species were moving into the transition zone when temperature was most stable. In a CCA of cavernicoles distribution data and environmental variables, 35% of variation in species-specific distributions was attributable to quadrat, and non-significant percentages were explained by date and environmental variables. Differences in assemblage structure among quadrats were

    In vivo dosimetry is one of the quality assurance tools used in radiotherapy to monitor the dose delivered to the patient. Electronic portal imaging device (EPID) images for a set of solid water phantoms of varying thicknesses were acquired and the data fitted onto a quadratic equation, which relates the reduction in photon beam intensity to the attenuation coefficient and material thickness at a reference condition. The quadratic model is used to convert the measured grey scale value into water equivalent path length (EPL) at each pixel for any material imaged by the detector. For any other non-reference conditions, scatter, field size and MU variation effects on the image were corrected by relative measurements using an ionization chamber and an EPID. The 2D EPL is linked to the percentage exit dose table, for different thicknesses and field sizes, thereby converting the plane pixel values at each point into a 2D dose map. The off-axis ratio is corrected using envelope and boundary profiles generated from the treatment planning system (TPS). The method requires field size, monitor unit and source-to-surface distance (SSD) as clinical input parameters to predict the exit dose, which is then used to determine the entrance dose. The measured pixel dose maps were compared with calculated doses from TPS for both entrance and exit depth of phantom. The gamma index at 3% dose difference (DD) and 3 mm distance to agreement (DTA) resulted in an average of 97% passing for the square fields of 5, 10, 15 and 20 cm. The exit dose EPID dose distributions predicted by the algorithm were in better agreement with TPS-calculated doses than phantom entrance dose distributions.

  9. Building air exhaustion device

    International Nuclear Information System (INIS)

    An opening is formed on the side wall of a building such as of a nuclear power plant, and a blow out panel is held (supported) by a clip for closing the opening. A large-diameter pipeline is connected at one end to the opening so as to cover the blow out panel, and immersed at the other end in a pool water. When a pipeline such as of main steam pipelines is ruptured in the building, high temperature and high pressure coolants are flown out from the ruptured port, and the pressure in the building is elevated. The blow out panel falls off from the side of the building by the elevation of the pressure in the building. Steams or compressed air discharged from the opening is introduced to the pool through the large diameter pipeline, then the steams are condensed by the pool water and radioactive materials contained in the condensed steams are kept in the pool water. Radioactive materials contained in the released compression air are also removed into the pool water. (I.N.)

    Three entrance channels 16O + 40Ca, 28Si + 28Si, and 32S + 24Mg forming the 56Ni compound nucleus have been studied in the energy range 5 to 17 MeVnucleon. Time-of-flight measurements provided mass identification and allowed for extraction of velocity distributions. These distributions were used to identify evaporation residues and to decompose the evaporation residues yeilds into complete and incomplete fusion components using evaporation code calculations. The velocity centroids as function of angle and mass are found to put constraints on the possible pre-equilibrium emission of light particles. 16 refs., 6 figs

    may distract fish away from fish pass entrances. The initial steps of the framework development have focused on the challenge of precise spatial data referencing in areas with limited sky view to navigation satellites. Platform tracking with a motorised Total Station, various satellite-based positioning solutions and simultaneous localisation and mapping (SLAM) based on stereo images have been tested. The effect of errors in spatial data referencing on ADCP-derived maps of flow features and bathymetry will be quantified through simultaneous deployment of these navigation technologies and the ADCP. This will inform the selection of a cost-effective platform positioning system in practice. Further steps will cover the quantification of uncertainties in ADCP data caused by highly turbulent flows and the identification of suitable ADCP data sampling strategies at fish passes. The final framework for fish pass assessment can contribute to an improved understanding of the interaction of fish and the complex hydraulic river environment.

    2009-01-01

    One of the most important goals of information management (IM) is supporting the knowledge workers in performing their works. In this paper we examine issues of relevance, linkage and provenance of information, as accessed and used by the knowledge workers. These are usually not adequately addressed in most of the IT based solutions for IM. Here we propose a non-conventional approach for building information systems for supporting the knowledge workers which addresses these issues. The approach leads to the ideas of building Information Warehouses (IW) and Knowledge work Support Systems (KwSS). Such systems can open up potential for building innovative applications of significant impact, including those capable of helping organizations in implementing processes for double-loop learning.

    We describe a project to capitalize on newly available levels of computational resources in order to understand human cognition. We will build an integrated physical system including vision, sound input and output, and dextrous manipulation, all controlled by a continuously operating large scale parallel MIMD computer. The resulting system will learn to 'think' by building on its bodily experiences to accomplish progressively more abstract tasks. Past experience suggests that in attempting to build such an integrated system we will have to fundamentally change the way artificial intelligence, cognitive science, linguistics, and philosophy think about the organization of intelligence. We expect to be able to better reconcile the theories that will be developed with current work in neuroscience.

  2. Carbon Efficient Building Solutions

    Full Text Available Traditionally, the Finnish legislation have focused on energy use and especially on energy used for heating space in buildings. However, in many cases this does not lead to the optimal concept in respect to minimizing green house gases. This paper studies how CO2 emission levels are affected by different measures to reduce energy use in buildings. This paper presents two real apartment buildings with different options of energy efficiency and power sources. The calculations clearly show that in the future electricity and domestic hot water use will have high importance in respect to energy efficiency, and therefore also CO2 equivalent (eq emissions. The importance increases when the energy efficiency of the building increases. There are big differences between average Finnish production and individual power plants; CO2 eq emissions might nearly double depending on the energy source and the power plant type. Both a building with an efficient district heating as a power source, and a building with ground heat in addition to nuclear power electricity as a complimentary electricity source performed very similarly to each other in respect to CO2 eq emissions. However, it is dangerous to conclude that it is not important which energy source is chosen. If hypothetically, the use of district heating would dramatically drop, the primary energy factor and CO2 eq emissions from electricity would rise, which in turn would lead to the increase of the ground heat systems emissions. A problem in the yearly calculations is that the fact that it is very important, sometimes even crucial, when energy is needed, is always excluded.

    Full Text Available Un proyectil de arma de fuego puede penetrar en el organismo por cualquier parte, originando una lesión cuya morfología puede ser muy variada en función de múltiples factores. No obstante, en ocasiones el lugar de entrada del proyectil puede coincidir con un orificio natural del cuerpo, por lo que la lesión externa no existe. Presentamos un caso de muerte por un único proyectil de arma de fuego cuyo lugar de penetración es uno de los orificios nasales, con la particularidad de que la bala quedó alojada en el interior del cuerpo, no existiendo por tanto lesión de salida. En estas circunstancias se hacen indispensables las técnicas radiológicas como paso previo a la autopsia.A firearm projectile can penetrate through any place of the body, causing injuries whose morphology can be different depending on several factors. However, sometimes the shotgun entrance hole coincides with a body orifice, so the entrance wound could not exist. The authors present a case of a death caused by a single firearm projectile which penetrated through one of the nostrils. The bullet was lodged inside of the body without an exit wound. In those circumstances the radiological techniques are indispensable before to perform the autopsy.

    2016-01-01

    The Cariaco Basin and the Gulf of Cariaco in Venezuela are two major basins along the seismogenic El Pilar right lateral fault, among which the Cariaco Basin is a pull-apart. Both basins are sites of anoxia and organic-rich deposits. To examine whether the sediments in the Gulf of Cariaco have recorded traces of historical or prehistorical earthquakes, we extracted and analyzed twelve 1 m-long gravity cores, sampling the last millennium sedimentation. We focused on analyzing the sediment sources with different techniques (particle size analysis, XRF, loss on ignition tests, magnetic properties, Rock-Eval pyrolysis, 14C dating). The results confirm that major upwelling occurs at the western gulf entrance and makes deep water flowing from the Cariaco Basin into the Gulf of Cariaco. These flows carry an organic-rich suspended load. Furthermore, we found evidence of a particular, widespread fine-grained siliciclastic deposit (named SiCL3) within the gulf, whose age suggests that it likely formed during the large 1853 AD earthquake that stroke the Cumaná city. We suggest that the earthquake-induced large submarine landslides that modified the topography of the gulf's entrance, which in turn promoted upwelling and open marine water flows from the Cariaco Basin. The layer SiCL3 would be the sediment load remobilized during this chain of events.

  17. Scan Quality and Entrance Skin Dose in Thoracic CT: A Comparison between Bismuth Breast Shield and Posteriorly Centered Partial CT Scans

    International Nuclear Information System (INIS)

    Objectives. To compare the effectiveness of the bismuth breast shield and partial CT scan in reducing entrance skin dose and to evaluate the effect of the breast shield on image quality (IQ). Methods. Nanodots were placed on an adult anthropomorphic phantom. Standard chest CT, CT with shield, and partial CT were performed. Nanodot readings and effective doses were recorded. 50 patients with chest CTs obtained both with and without breast shields were reviewed. IQ was evaluated by two radiologists and by measuring Hounsfield units (HUs) and standard deviation (SD) of HU in anterior subcutaneous region. Results. Breast shield and the partial CT scans reduced radiation to the anterior chest by 38% and 16%, respectively. Partial CT increased dose to the posterior chest by 37% and effective dose by 8%. Change in IQ in shield CT was observed in the anterior chest wall. Significant change in IQ was observed in 5/50 cases. The shield caused an increase of 20 HU (P = 0.021) and a 1.86 reduction in SD of HU (P = 0.027) in the anterior compared to posterior subcutaneous regions. Summary. Bismuth breast shield is more effective than the partial CT in reducing entrance skin dose while maintaining image quality

  18. A comparison of age-dependent entrance skin doses in pediatric chest exams with diagnostic reference levels for the Antioquia region of Colombia

    International Nuclear Information System (INIS)

    In pediatric radiology, radiological protection is of vital importance due to the great radio-sensitivity of body tissues in childhood, which can come to present stochastic effects as children have a longer life expectancy. The objective of this research is to establish diagnostic reference levels in chest exam pediatric patients. The study, carried out in one of the largest pediatric centers of the city of Medellin, the capital of the Department of Antioquia, consisted of the calculation of the Entrance Skin Dose (ESD) for a sample of 814 chest radiographic studies in the anteroposterior (AP) and left lateral (L LAT) projections, and it was compared with the doses obtained with the computational program PCXMC 2.0. For the estimate of the Entrance Skin Dose, data were collected from the exams, including the size of the radiation field, mAs and kVp. The ESD in chest exams for 5-year-old children was the only one that exceeded the international reference levels, giving evidence of the need to optimize the techniques used in this type of study in the institution under evaluation.

  14. Deactivation of Building 7602

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has sponsored research and development programs in Building 7602 at Oak Ridge National Laboratory (ORNL) since 1984. This work focused on development of advanced technology for processing nuclear fuels. Building 7602 was used for engineering-scale tests using depleted and natural uranium to simulate the nuclear fuel. In April 1994 the DOE Office of Nuclear Energy (NE) sent supplemental FY 1994 guidance to ORNL stating that in FY 1995 and beyond, Building 7602 is considered surplus to NE programs and missions and shall be shut down (deactivated) and maintained in a radiologically and industrially safe condition with minimal surveillance and maintenance (S ampersand M). DOE-NE subsequently provided FY 1995 funding to support the deactivation activities. Deactivation of Building 7602 was initiated on October 1, 1994. The principal activity during the first quarter of FY 1995 was removal of process materials (chemicals and uranium) from the systems. The process systems were operated to achieve chemical solution concentrations needed for reuse or disposal of the solutions prior to removal of the materials from the systems. During this phase of deactivation the process materials processed and removed were: (1) Uranyl nitrate solution 30,178 L containing 4490 kg of uranium; (2) Nitric acid (neutralized) 9850 L containing less than 0.013 kg of uranium; (3) Organic solution 3346 L containing 265 kg of uranium; (4) Uranium oxide powder 95 kg; and (5) Miscellaneous chemicals. At the end of December 1994, the process systems and control systems were shut down and deactivated. Disposition of the process materials removed from the process systems in Building 7602 proved to be the most difficult part of the deactivation. An operational stand down and funding reductions at Y-12 prevented planned conversion of the uranyl nitrate solution to depleted uranium oxide powder. This led to disposal of the uranyl nitrate solution as waste

    Recent accomplishments in buildings energy research by the diverse groups in the Energy Efficient Buildings Program at Lawrence Berkeley Laboratory (LBL) are summarized. We review technological progress in the areas of ventilation and indoor air quality, buildings energy performance, computer modeling, windows, and artificial lighting. The need for actual consumption data to track accurately the improving energy efficiency of buildings is being addressed by the Buildings Energy Data (BED) Group at LBL. We summarize results to date from our Building Energy Use Compilation and Analysis (BECA) studies, which include time trends in the energy consumption of new commercial and new residential buildings, the measured savings being attained by both commercial and residential retrofits, and the cost-effectiveness of buildings energy conservation measures. We also examine recent comparisons of predicted vs. actual energy usage/savings, and present the case for building energy use labels.

    International Nuclear Information System (INIS)

    Buildings 3506, the Waste Evaporator Facility, and 3515, the Fission Product Pilot Plant, at Oak Ridge National Laboratory (ORNL), are scheduled for decontamination and decommissioning (D and D). This Site Characterization Plan (SCP) presents the strategy and techniques to be used to characterize Buildings 3506/3515 for the purpose of planning D and D activities. The elements of the site characterization for Buildings 3506/3515 are planning and preparation, field investigation, and characterization reporting. Other level of effort activities will include management and oversight, project controls, meetings, and progress reporting. The objective of the site characterization is to determine the nature and extent of radioactive and hazardous materials and other industrial hazards in and around the buildings. This information will be used in subsequent planning to develop a detailed approach for final decommissioning of the facilities: (1) to evaluate decommissioning alternatives and design the most cost-effective D and D approach; (2) to determine the level and type of protection necessary for D and D workers; and (3) to estimate the types and volumes of wastes generated during D and D activities. The current D and D characterization scope includes the entire building, including the foundation and equipment or materials within the building. To estimate potential worker exposure from the soil during D and D, some subfoundation soil sample collection is planned. Buildings 3506/3515 are located in the ORNL main plant area, to the west and east, respectively, of the South Tank Farm. Building 3506 was built in 1949 to house a liquid waste evaporator and was subsequently used for an incinerator experiment. Partial D and D was done prior to abandonment, and most equipment has been removed. Building 3515 was built in 1948 to house fission product separation equipment. In about 1960, all entrances were sealed with concrete block and mortar. Building 3515 is expected to be

    2005-01-01

    The irreversibility due to laminar forced convection in the entrance region of a duct was studied by means of numerical simulation. Local entropy generation distributions and total entropy generation were obtained based on the entropy generation equation. The effect of Reynolds number on the irreversibility was studied for constant wall temperature and heat flux. The results showed that the irreversibility in the entrance region was different from that in the fully developed region. Reynolds number had a strong effect on the irreversibility in the entrance region. The entropy generation caused by temperature difference was relatively dominant over that caused by viscous flow. The irreversibility at constant wall temperature was different from that at constant wall heat flux.

  1. Radon in residential buildings

    International Nuclear Information System (INIS)

    For the investigation, a passive integrating radon dose meter developed at the KfK Karlsruhe was used. This institute also carried out the evaluation of all dose meters. The inquiry data were collected and statistically evaluated centrally by the Radiation Hygiene Institute of the German Health Authorities. Results obtained from almost 6.000 appartments show a distinct regional distribution of the measured values closely related to the geological conditions of the respected area. Surprisingly, there was little dependency on the building materials, with the exception of natural stone houses. The analysis showed that the structural characteristics of a building likely to influence the penetration of radon from the soil have a great effect on the Rn level. Generally, the frequency distribution of the measured values follows a logarithmic Gaussian distribution. Based on a median of 40 Bg/m3, the annual effective dose equivalent is about 1 mSv.

    2015-01-01

    Focusing on both homemade and commercial products, this book provides the reader with simple and straightforward information about the modelling and building of binoscopes. Binoscopes can be thought of as binoculars enlarged to the size of telescopes: essentially, a combination of the two. Constructing a binoscope is easier than most people think, but it still demands attention to detail and proper background knowledge. The author goes on to provide additional information about how to understand the products currently on the market, should the reader choose to purchase a binoscope instead of building one. Lastly, the book also compares binoscopes with telescopes in great detail, outlining the differences the reader can expect to see in the night sky from using both. The celestial views obtained with a binoscope, compared to a single telescope of the same aperture, are a very different experience and well worth the effort.

    Burberry, P.

    1978-01-01

    Ways in which buildings may be designed to increase thermal efficiency are discussed, giving first of all examples of thermal design in relation to climate. How the building itself may be designed to take advantage of solar energy and the ways in which heat loss takes place are described; the effect of design variables such as siting, volume, and insulation is shown. The book also reviews the development of thermal regulations for health and comfort and, more recently, energy conservation. It discusses the possitilities and difficulties of legislation for energy saving. The UK regulations are given in detail together with descriptions of the FHA and ASHRAE recommendations for the USA and the lastest Scandinavian norms. The author argues that no significant cost need be involved in many of the aspects of thermal design, e.g., shape and fenestration; and that these factors should automatically be taken into account by designers. Even existing buildings can be adapted in various respects to save energy consumption. The book concludes with an explanation of calculation methods for U-values, heat loss, plant sizing, seasonal heat requirements, and other procedures, amply illustrated with tables and graphs.

    2016-04-01

    Full Text Available This study investigated the effects of hospital Clown Doctors intervention on child and caregiver preoperative anxiety at the entrance to the surgery care unit and separation from caregivers. A total of 88 children (aged 4-12 years were assigned to one of the following two groups: Clown Doctors intervention or control group (standard care. Independent observational records using the modified Yale Preoperative Anxiety Scale instrument assessed children’s anxiety, while the State-Trait Anxiety Inventory measured caregiver’s state anxiety. In addition, caregivers assessed the children’s functional health problems by completing the Functional Status Questionnaire. Although no effects of Clown Doctors were found on children’s anxiety, results showed that both low functional health problems and Clown Doctors intervention were significant predictors of lower caregiver anxiety. Caregivers also reported being very satisfied with their intervention. Overall, this study demonstrated the positive role of Clown Doctors for caregivers at a specific paediatric hospital setting.

  9. Compliance with building energy regulations for new-build dwellings

    International Nuclear Information System (INIS)

    Despite increasingly stringent building energy regulations worldwide, non-compliance exists in practice. This paper examines the profile of compliance with building energy regulations for new-build dwellings. In total 404 new-build dwellings completed in the UK from 2006 to 2009 were investigated. Only a third of these dwellings were evidenced as being compliant with Building Regulations Part L (England and Wales). Such low compliance casts a serious concern over the achievability of the UK Government's target for all new-build homes to be ‘zero carbon’ from 2016. Clearly evidenced was a lack of knowledge of Part L and its compliance requirements among the supply and building control sides of new-build dwellings. The results also indicate that the compliance profile was influenced by factors including Standard Assessment Procedure (UK Government's methodology for energy efficiency) calculation submissions, learning and experience of builders and building controls with Part L, use of Part L1A checklist, the introduction of energy performance certificate (EPC), build method, dwelling type, and project size. Better compliance was associated with flats over houses and timber frame over masonry. The use of EPC and Part L1A checklist should be encouraged. Key to addressing the lack of compliance with building energy regulations is training. -- Highlights: ► There exists a lack of compliance, worldwide, with building energy regulations. ► The implementation of England and Wales building energy regulations is problematic. ► Training, learning and experience of builders and building control are critical. ► Energy performance certificate and Part L 2006 checklist helped achieve compliance. ► Flats achieved better compliance over houses; and timber frame over masonry.

  10. ANALYZING SHORT (100 METERS AND MIDDLE DISTANCE (800 - 1200 METERS RUNNING AND COORDINATION VALUES ACCORDING TO SPORTS BRANCHES OF STUDENTS WHO TAKE ENTRANCE EXAMS TO SPORTS HIGH SCHOOL

    2014-06-01

    Full Text Available In this study, t h e p u r p o s e was to determine the changes in accordance with running and coordination values of children who took the entrance examinations of sports high scholl in the 5 year period and assess them according to the branches as 100 and 800 meters running for female, 100 and 1200 meters running for men. In accordance with this aim, test values of total 1306 students (m = 1061, f = 245, average age = 14 who participated in entrance examinations in a 5 years duration including 2008, 2 009, 2010, 2011, 2012 years in the region of Antalya for sports high school were analyzed. As an statistical analyze, One way ANOVA and multiple comparison tests (which are LSD, Least Significant Difference tests were used. As a result of statistical anal yses, although the candidates who took the tests in the region of Antalya, change along 5 years duration, while obtaining a statistically significant difference in the running values of male children (p0,05. Likewise, while obtaining a statistically significant difference in 100 meters running values of female children (p0,05. In addition there was no any statistically significant difference in 100, 800 meters running values and coordination values of female children according to branches (p>0,05. Consequently, it can be suggested that there were no changes in speed times of both male and female children in along 5 years duration in region of Antalya. It can be inferred that while there is a significant change in values of running and coordination of males, the reason why female children were not able to show c hanges in their values should be because they show less imrovement in sports branches. In addition, male students in track and field branch gained the highest degrees both in 100 m and coordination tracks. Thus, it can be said that someone having good spee d has good coordination too.

  11. Dependence of deep-inelastic processes on entrance channel asymmetry and excitation energy. [506 to 732 MeV, angular distribution

    Energy Technology Data Exchange (ETDEWEB)

    Schmitt, R.P.

    1978-05-01

    The dependence of deep-inelastic processes on entrance channel asymmetry and on excitation energy was investigated. Thin targets of /sup nat/At, /sup 159/Tb, /sup 181/Ta and /sup 197/Au were bombarded with 620 MeV /sup 86/Kr ions. Additional measurements were performed on the reactions /sup nat/Ag + /sup 86/Kr and /sup 197/Au + /sup 86/Kr at 506 and 732 MeV incident energy. The energy spectra, the charge distributions and the angular distributions of these fragments were measured. At 620 MeV the energy spectra show that the distinction between quasi-elastic and deep-inelastic processes diminishes as the target mass is increased. The charge distributions, which are peaked at symmetry for /sup nat/Ag, tend to become increasingly asymmetric for the heavier systems. Likewise, the angular distributions exhibit a strong dependence on the entrance channel asymmetry. For the lightest system, /sup nat/Ag + /sup 86/Kr, the angular distributions are essentially forward peaked, aside from a separable quasi-elastic component. For the heaviest system, /sup 197/Au + /sup 86/Kr, the angular distributions are side-peaked. The transition between these two regimes occurs smoothly with increasing target mass. The results at 506 and 732 MeV show that the widths of the charge distributions are strongly dependent on the excitation energy. The angular distributions for the reaction /sup nat/Ag + /sup 86/Kr become increasingly more forward peaked at higher bombarding energies. The angular distributions for /sup 197/Au + /sup 86/Kr, which are strongly focused at 506 MeV, also tend to be more forward peaked at the highest incident energy. The results are interpreted by assuming that the projectile and target form an intermediate complex and that they exchange mass via a diffusion process. Because of the systematic nature of this study, the data should serve as a guide in the development of models of deep-inelastic processes.

Such a system has the capability to integrate and assess all data relative to building management. The information allows building managers to rationalize exploitation costs and to coordinate energy use with the activities in the building

  13. Building a leadership brand.

    Science.gov (United States)

    Ulrich, Dave; Smallwood, Norm

    2007-01-01

    How do some firms produce a pipeline of consistently excellent managers? Instead of concentrating merely on strengthening the skills of individuals, these companies focus on building a broad organizational leadership capability. It's what Ulrich and Smallwood--cofounders of the RBL Group, a leadership development consultancy--call a leadership brand. Organizations with leadership brands take an "outside-in" approach to executive development. They begin with a clear statement of what they want to be known for by customers and then link it with a required set of management skills. The Lexus division of Toyota, for instance, translates its tagline--"The pursuit of perfection"--into an expectation that its leaders excel at managing quality processes. The slogan of Bon Secours Health System is "Good help to those in need." It demands that its managers balance business skills with compassion and caring. The outside-in approach helps firms build a reputation for high-quality leaders whom customers trust to deliver on the company's promises. In examining 150 companies with strong leadership capabilities, the authors found that the organizations follow five strategies. First, make sure managers master the basics of leadership--for example, setting strategy and grooming talent. Second, ensure that leaders internalize customers' high expectations. Third, incorporate customer feedback into evaluations of executives. Fourth, invest in programs that help managers hone the right skills, by tapping customers to participate in such programs. Finally, track the success of efforts to build leadership bench strength over the long-term. The result is outstanding management that persists even when individual executives leave. In fact, companies with the strongest leadership brands often become "leader feeders"--firms that regularly graduate leaders who go on to head other companies. PMID:17642128

  14. Sustainable Development and Green Buildings

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available Global sustainability goals have led to the development of the green building movement. The Green Building Program, stemming from the movement, has had unprecedented success as it provides a quantifiable metric to people’s efforts towards sustainable development. Sustainable development and green buildings are often used interchangeably. Although, sustainable development and green buildings are related, they are not the same. This paper provides an overview of how green building relates to sustainable development practices. Sustainability also governs decisions concerning building materials. A comprehensive explanation of what constitutes a green building material is discussed and how renewable material like wood fare in the deciding criteria. There are many green building rating systems in place. United States Green Building Council administered Leadership in Energy and Environment Design (LEED is the global market leader in the rating systems. LEED is a commendable and grand effort in moving towards sustainable development by converting the built environment green. However, it does have certain pitfalls and challenges. Some of these challenges are with respect to policies on material selection and performance monitoring. The materials used in a project are considered at a common starting point and no consideration is given to the life cycle performance of the material. Statements concerning sustainability require validation, and Life Cycle Analysis (LCA is a tool that can provide such validity. This paper presents how beneficial it can be, when included, in the bigger scheme of green building rating systems and introduces an integrated design concept for green buildings.

    Science.gov (United States)

    Kung, YiHsiu Michelle

    With Asia's surging economies and urbanization, the region is adding to its built environment at an unprecedented rate, especially those population centers in China and India. With numerous existing buildings, plus a new building boom, construction in these major Asian cities has caused momentous sustainability challenges. This dissertation focuses on China's leading city, Shanghai, to explore and assess its existing commercial building energy policies and practices. Research estimates that Shanghai's commercial buildings might become a key challenge with regard to energy use and CO2 emissions as compared to other major Asian cities. Relevant building energy policy instruments at national and local levels for commercial buildings are reviewed. In addition, two benchmarks are established to further assess building energy policies in Shanghai. The first benchmark is based on the synthesis of relevant criteria and policy instruments as recommended by professional organizations, while the second practical benchmark is drawn from an analysis of three global cities: New York, London and Tokyo. Moreover, two large-scale commercial building sites - Shanghai IKEA and Plaza 66 - are selected for investigation and assessment of their efforts on building energy saving measures. Detailed building energy savings, CO2 reductions, and management cost reductions based on data availability and calculations are presented with the co-benefits approach. The research additionally analyzes different interventions and factors that facilitate or constrain the implementation process of building energy saving measures in each case. Furthermore, a multi-scale analytical framework is employed to investigate relevant stakeholders that shape Shanghai's commercial building energy governance. Research findings and policy recommendations are offered at the close of this dissertation. Findings and policy recommendations are intended to facilitate commercial building energy governance in Shanghai and

  20. Final report of the radiological release survey of Building 30B at the Grand Junction Office Facility

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) Grand Junction Office (GJO) occupies a 61.7-acre facility along the Gunnison River near Grand Junction, Colorado. This site was contaminated with uranium ore concentrates and mill tailings during vanadium refining activities of the Manhattan Engineer District, and during sampling, assaying, pilot milling, storage, and brokerage activities conducted for the U.S. Atomic Energy Commission's domestic uranium procurement program. The DOE Defense Decontamination and Decommissioning Program established the GJO Remedial Action Project (GJORAP) to clean up and restore the facility lands, improvements, and underlying aquifer. WASTREN-Grand Junction is the site contractor for the facility and the remedial action contractor for GJORAP. Building 30B and the underlying soil were found not to be radiologically contaminated; therefore, the building can be released for unrestricted use. Placards have been placed at the building entrances indicating the completion of the radiological release survey and prohibiting the introduction of any radioactive materials within the building without written approvals from the GJO Facilities Operations Manager. This document was prepared in response to a DOE-GJO request for an individual final release report for each GJO building
