    Full Text Available Inferior vena cava filters are important tools used to help prevent life-threatening pulmonary embolisms in hospitalized patients with contraindications to pharmacological prophylactic anticoagulation. This is a case report of a patient who had an inferior vena cava filter placed after a traumatic subdural hematoma. He made a complete recovery but was lost to follow-up until he presented 1825 days after filter deployment with abdominal pain discovered to be from penetration of the filter tines outside the lumen and into adjacent structures. We describe a case complicated by fibrotic tine entrapment with penetration to surrounding structures and discuss the technical approach used to free and eventually remove the long-standing filter.

    1989-01-01

    The Mary Kathleen uranium deposit was located in the North West region of the state of Queensland, Australia. It was discovered in 1954 and mined in two phases for a total of twelve years between 1958 and 1982. In October 1982 operations at the site ceased with the deposit virtually exhausted and all contractual commitments completed. From the outset, a site specific approach was adopted in developing the rehabilitation plan. Other sites'experience was evaluated but was adopted only if appropriate for Mary Kathleen. As a result of this approach a conceptual solution was established for each area within the site. Each solution was then used as the basis for detailed planning for rehabilitation of that area. The rehabilitation program commenced in mid 1982 and was completed in late 1985. Results of monitoring provided a strong basis for confidence that the objectives of the plan have been met, and allowed for the relinquishment of all the remaining mining leases in August 1987

    1978-01-01

    Mary Kathleen Uranium Ltd. recommenced operations in early 1976 following a twelve year period of care and maintenance. Several sections of the plant were modified or completely changed for the second operation. The most important change was the replacement of ion exchange with solvent extraction as the means of purifying and upgrading uranium rich solutions. Most of the problems experienced in the solvent extraction system originate from the leach liquor which has a strong tendency to form stable emulsions. This has been countered by some careful control of leaching conditions and by closer observation of operations in the solvent extraction area. Most problems have now been resolved and plant recoveries are quite satisfactory

  7. Rehabilitation of the Mary Kathleen uranium mining and processing site

    International Nuclear Information System (INIS)

    Ward, T.A.

    1985-09-01

    A detailed plan for the rehabilitation of the Mary Kathleen mining and processing site was developed prior to the closure of operations in late 1982. The plan was based on three basic principles of: making all areas safe for public access; removing all structures which could deteriorate and become unsightly or unsafe with time; and encouraging natural revegetation on erosion resistant surfaces. The aim was to leave the site in a safe and satisfactory condition, consistent with future land use in the area, requiring no foreseeable ongoing maintenance and a minimum of precautionary monitoring. When the programme has been completed, the only constraint on future land use will be the need to control building construction in the tailings/ evaporation, dumps and mine areas as a precaution against possible exposure to radon daughters. Appropriate radiation and water quality monitoring programmes were incorporated in the plan

    1983-01-01

    The Mary Kathleen uranium mine and treatment plant ceased operation in late 1982 and a plan for the closure and rehabilitation of the area was developed. The object of the plan is to make all areas safe, remove all non-permanent structures and encourage natural revegetation. The plan has been accepted by the Queensland Mines Department. The mine pit will be left stable, inaccessible to vehicles, and containing about 50 metres of water. Mine waste and borrow areas will be contoured, ripped and seeded to encourage revegetation. The treatment plant area will be cleared of all equipment and light structures, decontaminated and revegetated. The evaporation ponds will be dried out, precipitate and contaminated soil will be removed to the tailings dam, and the area will be contoured and revegetated. The tailings will be covered with one metre of waste rock and boreholes will be used to recover groundwater containing salts for storage in the pit

    1999-01-01

    Full text: The Mary Kathleen uranium deposit, in northwest Queensland, was discovered in 1954 and mined in 19561963 and 1976-1982. Rehabilitation of the site was completed in 1985 and the work won an award for environmental excellence. In 1999 gamma-ray data, plus stream sediment, soil, rock chip, mineral efflorescence, vegetation and water samples were collected from selected sites to assist in the examination of the current environmental status of the rehabilitated area. This paper presents preliminary results and interpretations. In the Mark Kathleen open pit, skarn type U-Th-REE mineralisation is hosted in amphibolite grade metamorphosed calc-silicate, mafic to intermediate igneous and sedimentary rocks. Remnant ore zones are composed of medium to coarse grained garnet and clinopyroxene, with accessory allanite, plagioclase, pyrrhotite, chalcopyrite and uraninite. Later retrograde alteration to chlorite, calcite, sericite, epidote and scapolite occurs. Fine grained uraninite is enclosed in allanite, and is partly replaced by metamict products nd traces of galena. Elevated gamma-ray readings in the open pit correspond to exposed ore lenses, the former haul road and abandoned ore stockpiles (up to 16 mSv/year). Surficial oxidation of ore and adjacent sulphide-bearing calc-silicate rocks has led to contemporary precipitation of yellow, orange, green and white mineral efflorescences on the pit walls. Wallrock oxidation of reactive sulphides (mainly pyrrhotite breakdown) produces acidic solutions, however, buffering reactions of these fluids with gangue calc-silicates and carbonate phases prevent low pH conditions from developing. The open pit lake is approximately 40m deep and contains saline (0.15%) surface waters which are Ca-, SO 4 -rich with elevated Cu, Fe, Mn, Ni, U and Zn at a pH of 6.11. Waste rock piles are up to 30m thick and have been covered by a thin veneer of benign waste. However, there are high radiation levels on several waste rock piles (up to 20

    Full Text Available Introduction Improving the efficiency of all agricultural operations has always been important for farmers and engineers. It is well known that the force required for cutting a soil using narrow blades is a function of soil and environmental physical properties, tool shape geometry and the tool’s surface characteristics like soil-tool adhesion and friction. Soil tool adhesion can reduce ploughing efficiency and quality. It may also halt the movement of tillage machines in more severe conditions. Adhesion can also disable some machine abilities, which can result in a significant reduction of machine performance. Adhesion of the soil to seed-bed preparation tools like furrowers can significantly affect the germination rate. Reducing soil tool adhesion of furrowers can reduce draft force and improve ploughing efficiency. Many researchers have worked on methods of reducing draft force by modifying the surface material and/or surface texture of the plough tools. A good prediction on draft force of a tool before producing it has always been important for farmers and engineers. There are some models for predicting the draft force of narrow blades in soil. McKyes-Ali’s model is widely used because of its accuracy and simplicity. Ultra-high molecular weight polythene (UHMW-PE is a polymer with ultra-high weight and long molecular chains and is well known for its outstanding physical and chemical properties and self-cleaning abilities, which reduce soil-tool adhesion. The aim of this study was to investigate usability of UHMW-PE coated furrower tines for draft force. Analytical and experimental investigations were carried out during the research. A comparison was conducted between the analytical and the experimental method. The results of this comparison can be used to determine reliability of the analytical model for predicting the draft force improvement caused by the surface modification on tines using different surface coatings.

    One way that people get infected with intestinal parasites is through the consumption of contaminated vegetables and fruits. This study aimed at determining the prevalence and predictors of parasitic contamination of fruits and vegetables collected from four local markets in Arba Minch town, Southern Ethiopia. A cross-sectional study was conducted from 1 to 21 September 2014 to determine the level of parasitic contamination of fruits and vegetables sold in Arba Minch town. A total of 360 samples of different types of fruits and vegetables were soaked in physiological saline, followed by vigorous shaking with the aid of a mechanical shaker for 15 minutes and then examined using the sedimentation concentration technique. Out of the 360 samples examined, 196 (54.4%) were contaminated with at least one type of parasite. Ascaris lumbricoides (20.83%) was the most frequently detected parasite and Isospora belli (3.06%) was the least frequently detected one. It was also observed that decreased parasitic contamination was significantly associated with washing the products before displaying it for selling (P parasitic infections from the consumption of raw vegetables and fruits in Arba Minch, Ethiopia. The authors believe that an effort should be made by the relevant bodies to reduce the rate of contamination of products with medically important parasites by educating the vendors and the community.

    Full Text Available This paper explains a model to predict the draft force acting on varying standard single tines by using principles of soil mechanics and soil profile evaluation. Draft force (Fd measurements were made with four standard single tines comprising Heavy Duty, Double Heart, Double Heart with Wings and Duck Foot. Tine widths were 6.5, 13.5, 45 and 40 cm, respectively. The test was conducted in a soil bin with sandy loam soil. The effects of forward speeds and working depths on draft forces were investigated under controlled lab conditions. Results were evaluated based on a prediction model. A good correlation between measured and predicted Fd values for all tines with an average absolute variation less than 15 % was found.

    Helminths affect the outcome of tuberculosis by shifting cell mediated immune response to humoral and by total suppression of the host immune system. On the reverse, Mycobacterium infection favors immune escape of helminths. Therefore assessing helminth co-infection rate and predisposing factors in tuberculosis patients is mandatory to set strategies for better case management. Facility based cross-sectional study was conducted in Arba Minch to assess the prevalence and associated factors of intestinal helminths among pulmonary tuberculosis patients from January to August, 2016. A structured questionnaire was used to capture data about socio-demographic characteristics, clinical history and possible risk factors for intestinal helminth infections. Height and weight were measured to calculate body-mass index. Appropriate amount of stool was collected and processed by direct saline and formol-ether concentration techniques following standard protocols. All the data were analyzed using SPSS version 20.0. A total of 213 (57.3% male and 42.7% female) pulmonary tuberculosis patients were participated in the study. The overall co-infection rate of intestinal parasites was 26.3%. The infection rate of intestinal helminths account 24.4% and that of intestinal protozoa was 6.1%. Ascaris lumbricoides accounted the highest frequency of 11.3%. Living in rural residence (AOR = 3.175, 95% CI: 1.102-9.153, p = 0.032), Eating vegetables/ fruits without washing or peeling off (AOR = 2.208, 95% CI: 1.030-4.733, p = 0.042) and having body-mass index intestinal helminth infection. The infection rate by intestinal helminths was 24.4%. Ascaris lumbricoides was the most prevalent helminth. Residence, habit of washing vegetables/fruits before use and body-mass index were associated factors with intestinal helminthiasis. Therefore health care providers should screen and treat TB patients for intestinal helminthiasis in order to ensure good prognosis.

    The standard treatment for chondroblastoma is surgery, which can be difficult and disabling due to its apo- or epiphyseal location. Radiofrequency (RF) ablation potentially offers a minimally invasive alternative. The often large size of chondroblastomas can make treatment with plain electrode systems difficult or impossible. This article describes the preliminary experience of RF treatment of chondroblastomas with a multi-tined expandable RF electrode system. Four cases of CT guided RF treatment are described. The tumour was successfully treated in all cases. In two cases, complications occurred; infraction of a subarticular chondroblastoma in one case and cartilage and bone damage in the unaffected compartment of a knee joint in the other. Radiofrequency treatment near a joint surface threatens the integrity of cartilage and therefore long-term joint function. In weight-bearing areas, the lack of bone replacement in successfully treated lesions contributes to the risk of mechanical failure. Multi-tined expandable electrode systems allow the treatment of large chondroblastomas. In weight-bearing joints and lesions near to the articular cartilage, there is a risk of cartilage damage and mechanical weakening of the bone. In lesions without these caveats, RF ablation appears promising. The potential risks and benefits need to be evaluated for each case individually. (orig.)

A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps.Case description: A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications.Clinical implications: Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.Keywords: foreign bodies/radiography, foreign bodies/complications, equipment failure, dental instrument, accidental ingestion

    The recommissioning of the plant at Mary Kathleen involved several distinct phases. The previous plant process was modified significantly, the plant capacity was increased by the addition of new equipment and the existing equipment was in most cases overhauled. This equipment was either reused in its original duty or relocated. Maintenance requirements after the plant was commissioned were high because of the amount of modified equipment and also because some old items of equipment were deliberately not overhauled during recommissioning. The equipment that was overhauled has operated reliably. However some new equipment has not been as satisfactory

    1984-01-01

    The Mary Kathleen uranium mine and treatment plant ceased operation in late 1982 and a plan for the closure and rehabilitation of the area was developed by Mary Kathleen Uranium Ltd in association with consultants. This paper describes some of the groundwater quality studies undertaken in support of the rehabilitation program including sampling within the tailings dam to determine the profile of radionuclides, accelerated leaching tests on tailings to estimate long-term release rates of radium, monitoring of piezometers to determine the rate of movement of contaminants, and disposal of acidic effluent by neutralization and ion exchange through infiltration trenches. From accelerated leaching tests, it is estimated that a maximum of 0.13% of 226 Ra will be leached from the tailings in the first 1,000 years. There is no evidence that uranium or any of its daughters is moving away from the waste disposal area. The movement of heavy metals, radionuclides and acidity is strongly retarded by the alkaline soils

    Experience has shown that imaging software and hardware installations at accelerator facilities needs to be changed, adapted and updated on a semi-permanent basis. On this premise the component-based core architecture of Video System 3 was founded. In design and implementation, emphasis was, is, and will be put on flexibility, performance, low latency, modularity, inter operability, use of open source, ease of use as well as reuse, good documentation and multi-platform capability. In the past year, a milestone was reached as Video System 3 entered production-level at PITZ, Hasylab and PETRA III. Since then, the development path has been more strongly influenced by production-level experience and customer feedback. In this contribution, we describe the current status, layout, recent developments and perspective of the Video System. Focus will be put on integration of recording and playback of video sequences to Archive/DAQ, a standalone installation of the Video System on a notebook as well as experiences running on Windows 7-64 bit. In addition, new client-side multi-platform GUI/application developments using Java are about to hit the surface. Last but not least it must be mentioned that although the implementation of Release 3 is integrated into the TINE control system, it is modular enough so that integration into other control systems can be considered.

    Radiofrequency ablation (RFA) is the gold standard for the treatment of symptomatic osteoid osteoma (OO) as RFA yields both a high success and low complication rate. It has been widely utilized over the years, but recurrences of OO after this treatment have been documented. These recurrences may be the result of various factors, including incomplete tumor ablation, and are significantly higher in lesions greater than 10 mm. Thus, the need to induce thermal ablation in a wider area led us to use a Multi-Tined Expandable Electrode System (MTEES). In this study we examined the efficacy and safety of RFA using a MTEES in symptomatic OO. Between January 2005 and June 2007, 16 patients with symptomatic OO were treated by CT-guided percutaneous RFA using a MTEES. The diameter of OO ranged from 6 to 15 mm (mean 10±2.6 mm). Patients were evaluated for clinical outcomes, complications and recurrence. Pain evaluation was assessed preoperatively, 2 weeks postoperatively and at last follow-up. Clinical follow-up was available for all patients at a mean of 84.3 months (range 73-96 months). Mean preoperative VAS score was 7.4 (range 5-9), two weeks after the procedure mean VAS score was 0.3 (range 0-1) with a mean change of -7.06 points (p<0.0001). At the last follow-up a complete relief from pain has been observed in all patients. No major and minor complications were observed nor recurrences. RFA using a MTEES has been effective, safe and reliable for the treatment of OOs. This system, by increasing the size of the necrosis, could be a viable alternative to the single needle electrode in lesions larger than 10 mm, reducing the risk of recurrence.

    Full Text Available In this paper the results of the energy audit of buildings in Arba Minch Institute of Technology AMIT are presented. The objective of the study was to identify the energy lossy applications activities and traditions and to suggest the least costly energy conservation mechanisms. All functional lighting systems office equipment desktop computers and water fixtures showerheads dishwashers toilet flushers and hand washers are taken into consideration for the study. Increased energy consumption due to daytime operation of lighting systems inactive mode operation office equipment and desktop computers and poor water management practices were the focus of the study. Based on the audit results poor water management practice in the campus contributes the most to the total energy loss followed by the inactive mode energy consumption of desktop computers and daytime operation of outdoor lighting systems. Therefore a significant amount of energy can be saved by practicing regular maintenance of water fixtures and pipes in the campus. Moreover awareness creation campaign can help a lot in reducing the energy loss which could be resulted from inactive mode energy consumption of computers and daytime operation of lamps. Installation of electronic day light control and motion detection systems can be potentially used to reduce the energy consumption of lighting systems operating in the daytime and in class rooms and halls both in the day and night time respectively.

By utilizing the notion of hegemonic masculinity, this paper observes the thoughts and decisions made by men in Kathleen Winter’s Annabel. This paper explores and re-examines the position of men in their society with reference to the effect of hegemonic masculinity, as proposed by Connell. It is also within the scope of the study to trace the position of men in the novel through a series of negotiations made within themselves. This study reveals the typical behavior of an alpha male of hegemonic masculinity in Annabel. For hegemony to pan out, all members of society should have respective social duties in order for the entire mechanism to function. The paper demonstrated that male characters of the novel exude the position of men in the hegemonic masculine setting by showcasing the firmness in making decisions, having knowledge on faith, religion, and monetary issues.

    This illustrated report subdivided in two parts presents the preliminary study of a project aiming at installing two small-scale hydroelectric schemes on the drinking water supply network of the Municipality of St-Gingolph, Switzerland. The upper-spring (La Tine) water can be used in a 44 kW hydro power scheme (elevation difference: 121 m; water volume through the turbine: 1,240,000 m{sup 3}/y). This water could be added to the one from the Clarive spring, enabling the installation a second hydro power scheme with a power of 291 kW (elevation difference: 337 m; water volume through the turbine: 2,740'000 m{sup 3}/y). The estimated cost of the produced electricity is attractive: CHF 0.16/kWh for the La Tine scheme; CHF 0.11 for the Clarive scheme. The author recommends the construction of both schemes.

    To compare two-dimensional (2D) and three-dimensional (3D) computed tomography (CT) measurements of ablation zones (AZs) related to the shaft of two different large-volume monopolar multi-tined expandable electrodes. Percutaneous radiofrequency (RF) ablation was performed in 12 pigs (81.6±7.8 kg) using two electrodes (LeVeen 5 cm, Rita XL 5 cm; n=6 in each group). Contrast-enhanced CT with the electrode shaft in place evaluated the AZ. The largest sphere centred on the electrode shaft within the AZ was calculated (1) based on the 2D axial CT image in the plane of the shaft assuming rotational symmetry of the AZ and (2) using prototype software and the 3D volume data of the AZ measured with CT. The mean largest diameter of a sphere centred on the electrode shaft was always smaller using the 3D data of the AZ than using 2D CT measurements assuming rotational symmetry of the AZ (3D vs 2D): LeVeen 18.2±4.8 mm; 24.5 ±3.1 mm; p=0.001; Rita XL 20.0±3.7 mm; 28.8±4.9 mm; p=0.0002. All AZ showed indentations around the tines. Two-dimensional CT measurements assuming rotational symmetry of the AZ overestimate the largest ablated sphere centred on the electrode shaft compared with 3D CT measurements. (orig.)

    Parmi les complications thrombotiques de la maladie cœliaque l'occlusion de la veine centrale de la rétine a été exceptionnellement décrite. Nous rapportons l'observation d'une patiente âgée de 27 ans chez qui le diagnostic de maladie cœliaque a été porté dans le cadre du bilan étiologique d'une occlusion de la veine centrale de la rétine. L'interrogatoire ne révélait pas de diarrhée chronique ou de douleurs abdominales. La présence d'un amaigrissement, d'une anémie ferriprive et d'une hypocholestérolémie ont permis l'orientation vers la maladie cœliaque. La positivité des anticorps anti endomysium et la biopsie duodénale montrant l'atrophie villositaire confirmaient ce diagnostic. Le régime sans gluten associé à un traitement par aspirine avait partiellement amélioré l'acuité visuelle chez notre patiente. Cette présentation atypique de la maladie cœliaque souligne la diversité des manifestations extra-digestives au cours de cette maladie et l'intérêt de penser à la maladie cœliaque même lorsque ces manifestations sont inaugurales.

    Although she was one of the most successful female scientists in twentieth-century Britain, the X-ray crystallographer Kathleen Yardley Lonsdale (1903-71) has received relatively little attention from historians of science. This paper, based on material from the recently opened Dame Kathleen Lonsdale Papers, argues that Lonsdale's scientific career was shaped in particular ways by her identity not just as a woman, but as a married woman and a mother. When interacting with her scientific colleagues, Lonsdale frequently had to confront the assumption that married women should not pursue scientific careers, an attitude shaped by British concerns about reasserting traditional gender roles after the World Wars I and II. Furthermore, although Lonsdale's husband, Thomas, was an ardent supporter of her career, in the early 1930s Lonsdale left research temporarily to care for her small children. Her desire to work from home during this period led her to pursue one of her most significant scientific projects: the creation of crystallographic reference tables. Lonsdale's own experiences, and those of her female students, led her to focus on issues of marriage and family when she began speaking and writing about women in science during the late 1960s.

Iz uvoda k monografiji Smrt kraljuje povsod in bela Smrt triumfira je jasno razvidno, da je bilo to mogoče najprej zato, ker je avtor kritično dekonstruiral tradicionalne paradigme, zlasti (umetnostnih ali literarnih »centrov« oziroma »obrobij«, pa tudi (slogovne ali idejne »naprednosti« oziroma »zaostalosti«, ki so v humanističnih vedah ovirale in v določeni meri še vedno ovirajo neobremenjeno raziskovanje del, kakršno je Prizorišče človeške smrti.

    House is the major site for malaria infection where most human-vector contact takes place. Hence, improving housing might reduce the risk of malaria infection by limiting house entry of vectors. This study aimed to explore the impact of screening doors and windows with wire meshes on density and entomological inoculation rate (EIR) of malaria vector, and malaria incidence, and assess the acceptability, durability, and cost of the intervention. The susceptibility status of malaria vector was also assessed. A two-arm randomized trial was done in Arba Minch Town, southwest Ethiopia. 92 houses were randomly included in the trial. The baseline entomological and malaria prevalence data were collected. The mosquito sampling was done twice per household per month by Centers for Diseases Control and Prevention (CDC) light traps for six months. The baseline prevalence of malaria was assessed by testing 396 (83% of the 447 study participants) household members in all the eligible houses. The 92 houses were then randomized into control and intervention groups using mosquito and malaria prevalence baseline data to make the two groups comparable except the intervention. Then, we put wire-mesh on doors and windows of 46 houses. Post-screening mosquito collection was done in each household twice per month for three months. Each household member was visited twice per month for six months to assess malaria episodes. The frequency of damage to different structure of screening was measured twice. In-depth interview was conducted with 24 purposely selected household heads from intervention group. Speciation of Anopheles mosquito was done by morphological key, and the circum-sporozoite proteins (CSPs) analysis was done using enzyme-linked immunosorbent assay. A generalized estimating equation with a negative binomial distribution was used to assess the impact of the intervention on the indoor density of vectors. Clinical malaria case data were analyzed using Poisson regression with

    A woman's satisfaction with labour and delivery care service has a good effect on her health and subsequent utilization of the services. Thus knowledge about women's satisfaction on labour and delivery care used to enhances the services utilization. The objective of this study was to assess the satisfaction of women's towards labour and delivery care service and identify factors associated it at public health facilities in Arba Minch town and the surrounding district, Gamo Gofa zone, southern Ethiopia. Facility based cross sectional study was conducted among women who gave birth at public health facility. A total 256 women who gave birth during the study period were included in the study. Data was collected using a structured questionnaire. Satisfaction level was measured using a 5 point-Likert scale questions. Data were entered using Epi data version 3.5.1 and analyzed using SPSS 20.0 statistical software. Factor analysis was employed for Likert scale questions to extract factor represented each of the scale which facilitate treatment of variable as continuous for further analysis. Bi-variate and multivariable logistic regression analysis was employed to identify association between women's satisfaction and predicator variables. Statistical significance was declared at P value labour and delivery care. Factors associated with women's satisfaction with labour and delivery care services include: not attending formal education [AOR = 8.00, 95% CI = (1.52, 12.27)] attending antenatal care four times and more [AOR = 5.00, 95% CI = (1.76, 14.20)] waiting below 15 minutes to be seen by health professional [AOR = 3.37, 95% CI = (1.14, 9.97)] and not paying for drugs and supplies [AOR = 6.19, 95% CI = (1.34, 18.59)]. Although majority of women were satisfied with the labour and delivery service they got, their level of satisfaction was influenced by educational status, number of ANC visits, waiting time, and payment for drug and supplies

    Full Text Available Communicative language teaching (CLT has been criticised on some counts both here and abroad. One of the reasons is that it is open to a number of interpretations. Another is its uncertain theoretical base. However, perhaps the most significant reason is that criticism of an approach or method in the course of time is natural and helpful. The adoption of outcomesbased education (OBE in South Africa requires certain adaptations and redefinition of language teaching. This article argues that CLT is appropriate to the needs of OBE, and highlights some of the aspects which must be reviewed if the needs of the majority of children are to be met.Verskeie aspekte van Kommunikatiewe-taalonderrig is hier en in die buiteland gekritiseer. Een van die redes is dat dit op verskillende maniere geinterpreteer kan word. Nog 'n rede is die vae teoretiese basis daarvan.

Die aanvaarding van OBE in SA vereis sekere aanpassings en 'n herdefiniering van taalonderrig. Hierdie artikel stel die standpunt dat KTO vir die behoeftes van OBE toepaslik is en lig sommige van die aspekte uit wat hersien sal moet word as daar aan die behoeftes van die meerderheid kinders voldoen wil word.

    Full Text Available The research of usernames in comments of online articles and on Twitter showed that users who comment online news tend to cover their identity more often than Twitter users. We assume that the reason for this is that online news commentators mostly express their opinion, which may differ from the point of view of the online news portal. Due to anonymity, the opinion can be intensified or even radicalized. Therefore, commentators wish to at least partially conceal their identity. On the other hand, Twitter users frequently reveal their identity in their username, namely by using their real name and/or surname since the main purpose of using Twitter is for private communication and entertainment. On Twitter, it is also possible to find individuals who conceal their identity in order to express their opinion; however, they are less frequent. In usernames, users of both CMC types frequently replace their real name and/or surname with words that relate to their personal features (location, religion, characteristics, activity, horoscope and age or express their interests (celebrities, nature, trademarks, interests, technology and mathematics, events, food. In this way, their identity is indeed obscure to some extent; however, they still express something about themselves. Users largely cover their identity by choosing an innovative username; they may use a general or neutral word or even construct their username in such way to make it difficult to determine its motivation. The analysis of the collected usernames also revealed some other username characteristics typical for online communication in general. In their usernames, users often play with language because they want the username to be innovative and unique in order to represent them online. Modifications of the text are frequent, i.e. switching letters or replacing them with numbers. Omitting diacritical signs (carons on č, š, ž is also particular as such letters are often substituted by c, s, z or by letter combinations. Numbers may be used only as indexes or they may indicate the user’s age or year of birth or even refer to a number known from popular culture. Username specific are also the ways of marking word boundaries – words are most often separated by using upper- or lowercase and underscores. Usernames are predominantly written in lowercase.

    Helminths/HIV co-infections are very common in developing countries, especially in Africa. The effect of overlapping distribution of HIV and helminths becomes important because concomitant infection may exacerbate disease outcome of HIV infection. The study aimed at determining the effect of deworming on the immune status of helminth/HIV coinfected Pre-ART HIV patients attending three health institutions in Southern Ethiopia. 97 HIV-positive Pre-ART individuals were observed into 2 groups on the basis of helminth co-infection and no infection. Out of these, 66 study participants were helminths/HIV co-infected and the remaining 31 study participants were helminths (-)/HIV (+) control. Helminth/HIV co-infected participants CD4+ T-cell count was done at baseline, after 15 weeks and 6 months after antihelminthics treatment. Data were analyzed using SPSS version 16. Ascaris lumbricoides was the highest prevalent soil transmitted helminths in Pre-ART individuals in this study. CD4+ T-cell count in the Ascaris lumricoides/HIV co-infected was significantly higher (P = 0.05) and (P intestinal helminth parasites detected in the study. In conclusion, this finding on Ascaris lumbricoides-specific nature of immune interaction in helminth/HIV co-infection may partly explain the inconsistent reports on the role of intestinal helminths on progression of HIV infection to AIDS. Therefore, a well-designed longitudinal study on helminth species-specific HIV/helminth co-infection will be needed to fully establish the possible benefits of deworming in intestinal helminth/HIV co-infection.

    Full Text Available Based on the research of many rock-hewn churches of the Romanian region, located in the Dobruja andaround the Carpathian mountain range, the author notes the existence there of a number of Christian churches belonging to the early Christian period and the early Middle Ages. According to the author, the religious buildingswere created for the most part of very strong material because of the highly volatile external environment, due to the pressure of the migratory and nomadic peoples. On the basis of new archaeological data it can be argued that in the territory of the future Moldova there was a diocese under the guidance of a chorbishop (bishop of rural settlements. The presence and discovery of a very valuable exhibit, which is a rare example of art, iconography and folklore heritage of Romanians in early Middle Ages (red brick with depictions, gives us the first written evidence of the presence of Christianity in this area.

  13. Tribute to: Self-administered nicotine activates the mesolimbic dopamine system through the ventral tegmental area [William Corrigall, Kathleen Coen and Laurel Adamson, Brain Res. 653 (1994) 278-284].

    2016-08-15

    In this paper, Dr. Corrigall and collaborators described elegant experiments designed to elucidate the neurobiology of nicotine reinforcement. The nicotinic receptor antagonist dihydro-β-erythroidine (DHβE) was infused in the ventral tegmental area (VTA) or nucleus accumbens (NAC) of rats trained to self-administer nicotine intravenously. Additionally, DHβE was infused in the VTA of rats trained to self-administer food or cocaine, and nicotine self-administration was assessed in rats with lesions to the peduculopontine tegmental nucleus (PPT). A number of key themes emerged from this fundamental study that remain relevant today. The primary finding was that infusions of DHβE in the VTA, but not in the NAC, lowered nicotine self-administration, suggesting that nicotinic receptors in VTA are involved in the reinforcing action of nicotine. This conclusion has been confirmed by subsequent findings, and the nature of the nicotinic receptors has also been elucidated. The authors also reported that DHβE in the VTA had no effect on food or cocaine self-administration, and that lesions to the PPT did not alter nicotine self-administration. Since this initial investigation, the question of whether nicotinic receptors in the VTA are necessary for the reinforcing action of other stimuli, and by which mechanisms, has been extensively explored. Similarly, many groups have further investigated the role of mesopontine cholinergic nuclei in reinforcement.

    This fascinating publication describes in depth the roles and responsibilities of forensic nurses in the US, who are often involved in the scientific investigation of violent and sexual crimes. However, these duties differ from those of nurses in forensic or secure settings in the UK, who work primarily with offenders who have mental health problems and who are in hospital, prison or police cells.

    Plastics are generally mixed with additives like plasticizers to enhance their flexibility, pliability, and elasticity proprieties. Plasticizers are easily released into the environment and are absorbed mainly through ingestion, dermal contact, and inhalation. One of the main classes of plasticizers, phthalates, has been associated with endocrine and reproductive diseases. In 2002, 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH) was introduced in the market for use in plastic materials and articles intended to come into contact with food, and it received final approval from the European Food Safety Authority in 2006. At present, there is limited knowledge about the safety and potential metabolic and endocrine-disrupting properties of DINCH and its metabolites. The purpose of this study was to evaluate the biological effects of DINCH and its active metabolites, cyclohexane-1,2-dicarboxylic acid (CHDA) and cyclohexane-1,2-dicarboxylic acid mono isononyl ester (MINCH), on rat primary stromal vascular fraction (SVF) of adipose tissue. DINCH and its metabolite, CHDA, were not able to directly affect SVF differentiation. However, exposure of SVF to 50 μM and 100 μM concentrations of MINCH affected the expression of Cebpa and Fabp4, thus inducing SVF preadipocytes to accumulate lipids and fully differentiate into mature adipocytes. The effect of MINCH was blocked by the specific peroxisome proliferator-activated receptor (PPAR)-α antagonist, GW6471. Taken together, these results suggest that MINCH is a potent PPAR-α agonist and a metabolic disruptor, capable of inducing SVF preadipocyte differentiation, that may interfere with the endocrine system in mammals. - Highlights: • DINCH and CHDA did not affect the adipogenesis of the SVF. • MINCH affected the adipogenesis of the SVF. • MINCH effect was blocked by the specific PPAR-α antagonist GW6471. • MINCH exerted a similar effect as MEHP on SVF adipogenesis. • DINCH/MINCH are potential metabolic

    The chronic administration of rHuEPO can engender side effects. An increase of the hematocritinduced by rHuEPO, by increasing the erythrocytosis, the blood viscosity and the shear stress onvascular surface, can be responsible of arterial high blood pressure and arterial thrombosis. Thepresence of a normal endothelial function and nitric oxide (NO) can counter the noxious effectsof rHuEPO.

  1. Low Volume, Funding, Staffing and Technical Problems are Key Reasons for Discontinuation of Chat Reference Services. A review of: Radford, Marie L., and M. Kathleen Kern. “A Multiple‐case Study Investigation of the Discontinuation of Nine Chat Reference Services.” Library & Information Science Research 28.4 (Sept. 2006: 521‐47.

    Full Text Available Objective – To investigate the reasons behind the cessation of 9 virtual (chat reference services.Design – Multiple case‐study investigationSetting – Academic, public, and special libraries in the United States.Subjects – Five academic libraries, 1 public library, and 3 library consortia.Methods – The initial method used to identify discontinued chat reference services was via a posting to DIG_REF, the digitalreference services listserv. From this initial posting, librarians on the list also suggested other cases, for a total of 7. Two cases later came to the authors’ attention and were added. The 9 cases included academic libraries, a public library, and consortia who used tools provided by four major software vendors, giving a good cross‐section of the types of libraries participating in VR and the major software packages available at the time. A contact person for each discontinued service was invited to participate. The participants were geographically scattered, so data were collected via e‐mail questionnaires, telephone interviews, and examination of available documents describing the services, audiences, demographics, operations, and any decision‐making processes either for starting or discontinuing the service. The authors then compared and contrasted results obtained from the 9 services. The authors analysed reasons for discontinuation of services, the decision making processes, volume of questions, service hours, marketing, evaluation, and whether the service might be restarted atsome time in the future.Main Results – Although the VR services discussed were being delivered by diverse organizations, some commonalities emerged. All 9 services used existing staff and added chat reference to their duties. In all but one case, the hours of service offered when VRbegan were within the hours that the libraries were already open to the public. In the exception (Case E, there were hours of service after the libraries were closed, from 7‐10 p.m. These shifts were covered by librarians working from home. Decisions to either begin or suspend services were generally made by small informal groups or committees. Some cases began with pilot studies and received positive responses. Other than these pilot studies, little pre‐planning appeared to have been done. For example, there were noextensive advance surveys or studies to determine potential demand or markets for the service, or projected costs and benefits. Only one service had a strong, multi‐stage evaluation plan. In future launches of virtual reference services, both extensive pre‐planning and detailed measures for evaluation could be helpful in avoidingsome problems. Major reasons for discontinuation fell into 6 categories: funding problems, staffing problems, technical problems, institutional culture conflicts, low usage overall or low usage by target populations. A table (Table 1 was included that actually listed 7 categories of reasons for discontinuation, but the last one listed, “Software Change,” is discussed as part of “Technical Problems” in the text, though it is separated in the table (527. This is not immediately clear in the article, and thus the table is slightly confusing. Four cases reported funding problems as the major reason for discontinuation. Low volume or low volume for target population were primary reasons for discontinuation by4 cases, and secondary reasons for discontinuation by 4 cases. If one combines primary and secondary categories in this table, low volume is the most frequently cited reason for discontinuation. Lowvolume was determined to be “driven by a complex combination of variables including marketing strategies, insufficient hours of operation, and [failure to provide] an ample amount of time for a service to gain momentum” (527‐528. Funding was cited as the primary reason for cancellation in 4 cases. Technical problems were listed as primary or secondary factors for suspension of service in 2 cases, and software change was the secondary factor behind the suspension of service in 2 cases; one service reported that up to one third of chat sessions were ‘lost” (527. In many cases, these sites were early adopters of VR, or even beta test sites, so technical issues are perhaps not surprising. Staffing was the primary or secondary reason for discontinuation in a total of 3cases. Staffing problems included insufficient questions to keep staff interested; however, concerns about extending servicehours and thereby putting additional pressure on existing staff were also raised. Clashes in institutional cultures were reported as secondary reasons for discontinuation of the service in 2 consortia.It should be noted that the sample size is small; as the authors point out, the literature on unsuccessful or discontinued virtual reference services is quite limited. Pop‐up surveys were used by some cases to evaluate service success and user satisfaction. User satisfaction was reported as being high, but return rates for the surveys were very low, as can be expected since pop‐ups are often blocked or ignored. The authors recommend alternative means of evaluation, such as focus groups and more detailed surveys. The authors also discuss alternative technologies and user expectations for services such as IM or SMS text messaging, and suggest evaluation of user expectations and desires in these areas. One question which arose was what constituted success in chat reference – was it usage/volume, or some other measure, suchas whether chat reference queries were answered correctly more frequently than reference questions asked in other ways, such as by telephone or in person. Other key concerns identified include the importance of strong marketing, service usability, and the importance in a consortial environment of having someone responsible on a fulltime basis for directing and spearheading the project. Many of the suspended services reported that they could potentially become re‐interested in VR service, as issues are resolved and the technologies available mature. Finally, the authors provide detailed recommendations for single and consortial VR services, and offer directions for future research. Some suggestions for future research include ways to bridge the apparent gulf between expectations and technological preferences of users versus those of librarians and others staffing these services, as they often appear to have marked differences. Other areas of interest could include causes for low question volume, and possible relationships among various factors contributing to such poor usage along with an investigation of what makes successful services work well. Research on IM or SMS reference services as compared to those using other chat technologies and cost‐effectiveness studies or evaluations based on goals and measured outcomes are also needed.Conclusion – VR services have had erratic success rates and bumpy beginnings, but many libraries report continued interest The libraries in this study all indicated that they would consider, or are considering, restarting such services. Issues of staffing, technological usability and reliability, institutional culture, funding, marketing, and volume are key. As services and technologies mature, interest in offering VR services in one form or another continues to grow.

    Full Text Available Objective – To determine whether three competing citation tracking services result in differing citation counts for a known set of articles, and to assess the extent of any differences.Design – Citation analysis, observational study.Setting – Three citation tracking databases: Google Scholar, Scopus and Web of Science. Subjects – Citations from eleven journals each from the disciplines of oncology and condensed matter physics for the years 1993 and 2003.Methods – The researchers selected eleven journals each from the list of journals from Journal Citation Reports 2004 for the categories “Oncology” and “Condensed Matter Physics” using a systematic sampling technique to ensure journals with vary ingimpact factors were included. All references from these 22 journals were retrieved for the years 1993 and 2003 by searching three databases: Web of Science, INSPEC, and PubMed. Only research articles were included for the purpose of the study. From these, a stratified random sample was created to proportionally represent the content of each journal (oncology 1993: 234 references, 2003: 259 references; condensed matter physics 1993: 358 references, 2003: 364 references. In November of 2005, citations counts were obtained for all articles from Web of Science, Scopus and GoogleScholar. Due to the small sample size and skewed distribution of data, non‐parametric tests were conducted to determine whether significant differences existed between sets.Main Results – For 1993, mean citation counts were highest in Web of Science for both oncology (mean = 45.3, SD = 77.4 and condensed matter physics (mean = 22.5, SD= 32.5. For 2003, mean citation counts were higher in Scopus for oncology (mean = 8.9,SD = 12.0, and in Web of Science for condensed matter physics (mean = 3.0, SD =4.0. There was not enough data for the set of citations from Scopus for condensed matter physics for 1993 and it was therefore excluded from analysis. A Friedman test to measure for differences between all remaining groups suggested a significant difference existed, and so pairwise post‐hoc comparisons were performed. The Wilcoxon Signed Ranked tests demonstrated significant differences “in citation counts between all pairs (p Conclusion – The study does not confirm the authors’ hypothesis that differing scholarly coverage would result in different citation counts from the three databases. While there were significant differences in mean citation rates between all pairs of databases except for Google Scholar and Scopus in condensed matter physics for 2003, no one database performed better overall. Different databases performed better for different subjects, as well as for different years, especially Scopus, which only includes references starting in 1996. The results of this study suggest that the best citation database will depend on the years being searched as well as the subject area. For a complete picture of citation behaviour, the authors suggest all three be used.

    Utica was a flourishing port city in northern Tunisia since the Phoenician times, 12-9th century B.C., until the 4th century A.D.. However, at present it is located 10 km from the coastline after very fast late Holocene progradation of the Mejerda River delta into the bay of Utica. This fast delta progradation occurred after Mejerda River captured Tine River increasing 140 % the river catchment area. Charcoal fragments present in the youngest Tine river terrace at the wind gap give a conventional radiocarbon age of 3240 +/- 30yr BP, indicating that the capture occurred after this date. Quaternary fluvial terraces located in the Tine River paleovalley have been folded and uplifted above a fold related to the active El Alia Tebousouk reverse fault (ETF). Continued uplift of the Tine River valley above the ETF favoured headward erosion of the Medjerda river tributaries creating a transverse drainage that captured Tine River. This capture produced an important change in sediment discharge along the northern Tunisia coast driving sediments to the Gulf of Tunis instead of feeding the Tyrrhenian Sea through the Ichkeul and Bizerte lakes. Although anthropogenic derived degradation of northern Tunisia land for agricultural purposes probably influenced the increase in sediment into the Utica bay, the main cause of rapid progradation of the Medjerda River delta during the late Holocene is related to its increase in drainage area after capturing the Tine River. This process was mostly driven by local contractive tectonics linked to the seismogenic Alia Tebousouk reverse fault.

  8. Grid sleeve bulge tool

    International Nuclear Information System (INIS)

    Phillips, W.D.; Vaill, R.E.

    1980-01-01

    An improved grid sleeve bulge tool is designed for securing control rod guide tubes to sleeves brazed in a fuel assembly grid. The tool includes a cylinder having an outer diameter less than the internal diameter of the control rod guide tubes. The walls of the cylinder are cut in an axial direction along its length to provide several flexible tines or ligaments. These tines are similar to a fork except they are spaced in a circumferential direction. The end of each alternate tine is equipped with a semispherical projection which extends radially outwardly from the tine surface. A ram or plunger of generally cylindrical configuration and about the same length as the cylinder is designed to fit in and move axially of the cylinder and thereby force the tined projections outwardly when the ram is pulled into the cylinder. The ram surface includes axially extending grooves and plane surfaces which are complimentary to the inner surfaces formed on the tines on the cylinder. As the cylinder is inserted into a control rod guide tube, and the projections on the cylinder placed in a position just below or above a grid strap, the ram is pulled into the cylinder, thus moving the tines and the projections thereon outwardly into contact with the sleeve, to plastically deform both the sleeve and the control rod guide tube, and thereby form four bulges which extend outwardly from the sleeve surface and beyond the outer periphery of the grid peripheral strap. This process is then repeated at the points above the grid to also provide for outwardly projecting surfaces, the result being that the grid is accurately positioned on and mechanically secured to the control rod guide tubes which extend the length of a fuel assembly

    2012-01-01

    Ravnatelj svojim djelovanjem (bez obzira ovisi li o situaciji ili ciljevima) ne utječe samo na konačan uspjeh škole, nego i na međuljudske odnose, na školsku klimu, na motivaciju nastavnika i organizaciju rada škole. Upravo iz tog razloga nužno je ispitati socijalnu kompetenciju ravnatelja kako bi se potaknulo njihovo osposobljavanje, a potom i njihovo usavršavanje, jer vježbom se socijalne vještine mogu usavršiti (Goleman, 2008).

    Full Text Available Behailu Merdekios1, Adebola A Adedimeji2 1College of Medicine and Health Sciences, Arba Minch University, Ethiopia; 2Albert Einstein College of Medicine, Jack and Pearl Resnick Campus, New York, USA Background: In Ethiopia, Progress in Reducing Mother-to-Child-Transmission (PMTCT of human immunodeficiency virus (HIV is being curtailed by behavioral and cultural factors that continue to put unborn children at risk, and mother-to-child transmission is responsible for more than 90% of HIV infection in children. The objective of this study was to assess PMTCT services by examining knowledge about reducing vertical transmission among pregnant women. Methods: A multistaged sampling institution-based survey was conducted in 113 pregnant women in Arba Minch. Qualitative and quantitative data were obtained. Results: Of the 113 respondents, 89.4% were from Arba Minch, 43.4% were at least 25 years of age, 73.4% had formal education at primary level or above, 100% reported acceptance of voluntary counseling and testing, 92.0% were knowledgeable about mother-to-child transmission, and 90.3% were aware of the availability of the PMTCT service in the health facility. Of 74 HIV-positive women in PMTCT, only three (4.1% had had skilled birth attendants at delivery. There was an unacceptable degree of loss of women from PMTCT. Maternal educational level had a statistical association with income (P < 0.001 and voluntary counseling and testing for pregnant women (P < 0.05. Factors that determined use of PMTCT included culture, socioeconomic status, and fear of stigma and discrimination. Conclusion: In the area studied, intervention to reduce mother-to-child transmission of HIV is failing to reach its goal. This is an alarming discovery requiring quick reconsideration and strengthening of preventive strategies at all levels. Keywords: human immunodeficiency virus, mother-to-child transmission, pregnant women, Ethiopia

    To prospectively optimize multistep algorithms for largest available multitined radiofrequency (RF) electrode system in ex vivo and in vivo tissues, to determine best energy parameters to achieve large predictable target sizes of coagulation, and to compare these algorithms with manufacturer's recommended algorithms. Institutional animal care and use committee approval was obtained for the in vivo portion of this study. Ablation (n = 473) was performed in ex vivo bovine liver; final tine extension was 5-7 cm. Variables in stepped-deployment RF algorithm were interrogated and included initial current ramping to 105 degrees C (1 degrees C/0.5-5.0 sec), the number of sequential tine extensions (2-7 cm), and duration of application (4-12 minutes) for final two to three tine extensions. Optimal parameters to achieve 5-7 cm of coagulation were compared with recommended algorithms. Optimal settings for 5- and 6-cm final tine extensions were confirmed in in vivo perfused bovine liver (n = 14). Multivariate analysis of variance and/or paired t tests were used. Mean RF ablation zones of 5.1 cm +/- 0.2 (standard deviation), 6.3 cm +/- 0.4, and 7 cm +/- 0.3 were achieved with 5-, 6-, and 7-cm final tine extensions in a mean of 19.5 min +/- 0.5, 27.9 min +/- 6, and 37.1 min +/- 2.3, respectively, at optimal settings. With these algorithms, size of ablation at 6- and 7-cm tine extension significantly increased from mean of 5.4 cm +/- 0.4 and 6.1 cm +/- 0.6 (manufacturer's algorithms) (P mean diameter in specified time: 5.5 cm +/- 0.4 in 18.5 min +/- 0.5 (5-cm extensions) and 5.7 cm +/- 0.2 in 21.2 min +/- 0.6 (6-cm extensions). Large zones of coagulation of 5-7 cm can be created with optimized RF algorithms that help reduce number of tine extensions compared with manufacturer's recommendations. Such algorithms are likely to facilitate the utility of these devices for RF ablation of focal tumors in clinical practice. (c) RSNA, 2010.

    Significant advances into the post-depositional (or diagenetic) chemistry of radionuclides have been made by developing a method to study the pore water chemistry of 239 240 Pu, 137 Cs, 55 Fe, and several natural radionuclides (U, Th, Ra, 210 Po, 210 Pb). Field (box coring) and laboratory studies demonstrate that 239 240 Pu has an insignificant diagenetic mobility in nearshore sediments. 137 Cs, in contrast, appears to be significantly mobile and undergoes rapid ion-exchange reactions, while U has an active redox-complexation sediment chemistry. A major emphasis has been on Windscale nuclear fuel reprocessing radionuclide studies in the Irish Sea, Minch, North Sea, and Norwegian and Greenland Seas. This work has demonstrated the dramatic penetration of these radionuclides (especially 137 Cs) through the Irish Sea, Minch, and North Sea into the upper 1000 m of the Norwegian and Greenland Seas. Measurements of 137 Cs, 134 Cs, and 90 Sr from samples collected in the Arctic and North Atlantic Oceans during Transient Tracers in Oceanography (TTO) cruise in 1981 provide a valuable and unique set of data to the tracer studies in the North Atlantic Ocean

    Swine manure is used as a soil fertilizer in South Brazil. Commonly, it is applied continuously and in great amounts over surfaces with an important relief and without facilities that avoid water erosion. Thus, this manure is a potential risk of environmental pollution, mainly for the eutrophication of water bodies due to a runoff rich in nutrients. The aim of this work was to assess some soil hydrological parameters and to quantify the dissolved phosphorus losses in the runoff from no-tilled soils after the application of swine liquid manure. The experiment was carried out in the Highlands of Santa Catarina State, Brazil, in June 2009, over a Nitisol. On field plots, a 90-minute simulated rainfall test was performed with a rotating boom rainfall simulator and rainfall intensity of 70 mm h-1. Prior to the rainfall simulation, sowing was performed using a disk planter either with or without tines. Spacing between lines was 0.5 m. Swine liquid manure was applied at rates of 0.0, 30 and 60 m3ha-1 to the plots planted using tines; whereas it was applied at 15, 45 e 75 m3ha-1 to the plots were no tines were used for planting. During rainfall simulation, readings of runoff rate were taken each five minutes; total water loss was calculated by integrating all the 5-minute readings. Runoff samples were collected at 10 minutes intervals, and they were filtered through a 0.45 μm filter to determine dissolved phosphorus. Hydrological variables were significantly affected by the use of tines, which favoured infiltration and reduced runoff as compared to the non-use of tines. Runoff started at 28 and 11 minutes, water losses were 252 and 467 m3 ha-1, maximum runoff rate were 29 and 42 mm h-1 and constant rates of infiltration were 41 and 28 mm h-1, for treatments with and without tines, respectively. Dissolved phosphorus increased with the rate of swine liquid manure applied, with a trend to decrease from the beginning to the end of rainfall. The highest concentration was 0

    that pre- and post-emergence harrowing interact positively, that a combination gives more stable weed control effects than pre- and post-emergence weed harrowing used alone, and that a harrow type with bent tines is more aggressive and suitable on hard-packed soils than a harrow with strait tines...... the average effect of post-emergence harrowing was 47% on weed density and 41% on weed biomass. The combined effect of pre- and post-emergence weed harrowing was 61% on weed density and 54% on weed biomass. The combination did not give more stable weed control effects than pre- and post-emergence weed...... harrowing used alone. Pre-emergence harrowing increased the average crop yield by 6.2%, post-emergence harrowing by 4.0% and the combined effect was 10%. Crop yield was mainly increased on hard-packed soils.

    Atypical two-tine tuning fork is barely audible when held vibrating at an arm's length. It is enough, however, to touch its base to a table or, better, to a resonance box and the emitted sound becomes much louder. An inquiring student may pose questions: (1) Why is a bare tuning fork such a weak emitter of sound? (2) What is the role of the…

    Purpose. During radiofrequency ablation (RFA), there is a risk that the multitined expandable electrode will come into contact with one of the surgical staples used to treat local recurrence after surgical operations. Our objective was to evaluate whether a surgical staple would influence the RFA of egg white using a multitined expandable electrode. Methods. Multitined expandable electrodes, LeVeen needles (expandable diameter 3.0 cm), were sunk into an egg white bath with (a) no surgical staple, (b) a surgical staple touching one of the tines, or (c) a surgical staple touching two of the tines simultaneously. By connecting the LeVeen needle and copper plate at the bottom of the bath, RFA was then performed on the egg whites as a substitute for human tissue. Ten egg white baths were ablated under each of conditions (a), (b), and (c), for a total of 30 sets of coagulated egg white. Results. There was no significant difference in the time from the power-on to the roll-off (i.e., the completion and shutting off of the electric circuit) or in the maximum diameter of the thermal lesion between conditions (a) and (b) or (a) and (c). However, the minimum diameter of the thermal lesion was significantly smaller in (c) compared with (a) (p < 0.01). Conclusions. Surgical staples have the capacity to interfere with the electromagnetic field and decrease the minimum diameter of the thermal lesion in the event that a staple touches two of the tines of a multitined expandable electrode during RFA. Although the difference might be small enough to be neglected under many clinical circumstances, we recommend that, if possible, the tines not be expanded near metallic material

  13. Development and appraisal of economical and sustainable approach for weed management in drill seeded aerobic rice (oryza sativa l.)

    2012-01-01

    Conventional rice cultivation by puddling and transplanting is a labor intensive activity. Water scarcity is a threat for the sustain ability of transplanted rice. In many areas of Asia, rice transplantation of rice is being replaced by direct seeding as farmers tried to solve the problems of labor cost and water scarcity but weed control is one of the major constraints to direct seeding. So, to control weeds in direct seeded rice present studies were designed. A two years study was conducted to develop sustainable and economical methods for managing weeds in aerobic rice grown by dry direct-seeding at Student's Farm, Department of Agronomy, University of Agriculture, Faisalabad during the years 2008 and 2009. Experiment was laid out in RCBD with five weed management strategies: hand weeding, hoeing with kasula, inter-row cultivation with tine cultivator, inter-row cultivation with spike hoe and chemical control with Nominee 100 SC along with control (no weeding). Weed dry weight was 300 g m/sup -2/, 257 g m/sup -2/, 225 g m/sup -2/ and 157 g m/sup -2/ less in hand weeding, hoeing, tine cultivator and Nominee 100 SC respectively than no weeding. Paddy yield was 221%, 203%, 181% and 105% more in hand weeding, hoeing, tine cultivator and Nominee 100 SC respectively than no weeding. (author)

    Full Text Available Jalle Teferi,1 Zewdu Shewangizaw2 1Addis Ababa Health Bureau, Zewuditu Specialized Hospital, Addis Ababa, Ethiopia; 2College of Medicine and Health Sciences, Arba Minch University, Arba Minch, Ethiopia Abstract: Religious and sociocultural beliefs influence the nature of treatment and care received by people with epilepsy. Many communities in Africa and other developing nations believe that epilepsy results from evil spirits, and thus, treatment should be through the use of herbaceous plants from traditional doctors and religious leadership. Community-based cross-sectional study designs were used to assess the knowledge, attitude, and practice related to epilepsy and its associated factors by using a pretested, semi-structured questionnaire among 660 respondents living in Sululta Woreda, Oromia, Ethiopia. According to the results of this study, 59.8% of the respondents possessed knowledge about epilepsy, 35.6% had a favorable attitude, and 33.5% of them adopted safe practices related to epilepsy. The following factors had significant association to knowledge, attitude, and practice related to epilepsy: being rural dwellers, living alone, those with more years of formal education, heard information about epilepsy, distance of health facility from the community, had witnessed an epileptic seizure, age range from 46 years to 55 years, had heard about epilepsy, prior knowledge of epilepsy, occupational history of being self-employed or a laborer, history of epilepsy, and history of epilepsy in family member. The findings indicated that the Sululta community is familiar with epilepsy, has an unfavorable attitude toward epilepsy, and unsafe practices related to epilepsy, but has a relatively promising knowledge of epilepsy. Keywords: Oromia, favorable attitude, safe practice, rural

    The world shattering events of the mid 1940's to mid 1950s led to a favourable attitude towards Mary Kathleen first operations. The expectation and intention was that the Australian uranium output would be used to further Britain's nuclear station program, and hopefully to improve Australia's industrial base. The book describe the first operating period at Mary Kathleen, a very successful one, signaling a return to major innovative mining development in Australia. It started in 1954 when the uranium deposit was discovered and finished by mid-December 1963 when production team departed by Peter Wreford left Mary Kathleen and 'care and maintenance' period began. The author emphasises the human side of the operation and the excitement created by the technical and financial success. It is shown that the public perception of the usefulness of its product and the quality of living offered by the newly-built mining town contributed greatly to job satisfaction and to an atmosphere that encouraged innovation. ills

  9. Ultrasound-Guided Cervical Medial Branch Radiofrequency Neurotomy: Can Multitined Deployment Cannulae Be the Solution?

    Science.gov (United States)

    Finlayson, Roderick J; Thonnagith, Atikun; Elgueta, Maria Francisca; Perez, Jordi; Etheridge, John-Paul B; Tran, De Q H

    Novel multitined cannulae constitute an attractive option for ultrasound-guided radiofrequency neurotomy of cervical medial branches. The deployment tines increase the cannula's active area, thus altering its lesion size. Despite their theoretical benefits, multitined cannulae have not been assessed. In this bench study, we sought to investigate the lesions produced by a standard 18-gauge and 2 commercially available multitined deployment cannulae. We created ex vivo models to evaluate lesion morphology at a periosteal interface using approach angles likely to be encountered during an ultrasound-guided technique. Two ex vivo models were assembled using chicken breast tissue and bovine tibia. Monopolar lesions were carried out with 3 commercially available cannulae (18-gauge curved [S], 17-gauge with laterally deploying tines [N], and 18-gauge with distally deploying tines [T]). All cannulae were positioned at 0, 25, 45, and 90 degrees to the periosteal plane. For each angulation and cannula, 2 series of measurements were recorded to document lesion morphology in the axial and sagittal planes. Data collected included the lesion's surface area, shape, and dimensions relative to the needle tip. A total of 240 lesions were analyzed. The performances of S and N cannulae were significantly affected by approach angle, with lesion size decreasing as the angle increased. In contrast, T cannulae displayed similar lesion surface areas at 0 and 90 degrees. The multitined N and T cannulae produced the largest lesions at 0/25 and 90 degrees, respectively. Lesion height varied inversely according to approach angle for S and N cannulae, whereas T cannulae displayed stable characteristics. Unlike their S and N counterparts, T cannulae demonstrated stable lesion characteristics at varying approach angles.

  10. Dama roberti, a new species of deer from the early Middle Pleistocene of Europe, and the origins of modern fallow deer

    Science.gov (United States)

    Breda, Marzia; Lister, Adrian M.

    2013-06-01

    The ancestry of the modern fallow deer, Dama dama, has been tentatively traced back to Pliocene/Early Pleistocene forms referred to 'Pseudodama', characterized by unpalmated three- or four-point antlers. By the late Middle Pleistocene, Dama with palmated antlers appears, as Dama dama clactoniana. However, fallow deer from the interim period, the early Middle Pleistocene, are poorly-known. A new specimen from Pakefield (Suffolk, UK), represented by a portion of cranium with a substantial part of both antlers plus a mandible and scapula, is the most complete medium-sized deer specimen from the British early Middle Pleistocene (ca 700 ka). The position and orientation of the basal tine, together with dental characters and mandibular morphology, are typical of fallow deer. The narrow palmation is reminiscent of D. dama clactoniana, but the lack of palmation tines is unique. Moreover, the lack of second (and third) tines in an adult specimen differs from both D. dama dama and D. d. clactoniana, being a primitive character shared with the last representatives of 'Pseudodama' which, on the other hand, has a circular beam lacking any palmation. This combination of features justifies the erection of a new species provisionally placed within the genus Dama, Dama roberti n. sp. Another specimen, from Soleilhac (Auvergne, France), represented by portions of the two antlers, a mandible and a tibia, shares antler morphology with the Pakefield specimen and can be ascribed to the same new species. Isolated antler and dental remains from coeval British sites are tentatively ascribed to D. roberti n. sp. The new species has implications for the ancestry of modern fallow deer.

    2017-04-01

    A Medtronic MICRA transcatheter pacing system (Medtronic, Minneapolis, MN, USA) was implanted in an 86-year-old patient with sick sinus syndrome and left bundle branch block after transfemoral aortic valve implantation. During implantation she developed a persistent complete heart block due to manipulation with the large-bore delivery catheter. Two weeks later, acute pacemaker dysfunction occurred due to massive increase of pacing threshold and impedance without obvious pacemaker dislocation or myocardial perforation. Recurrent capture failure was seen with pacing output set at 5 V/1.0 ms. Hence, microdislocation or fixation of the tines in the right ventricular trabeculae has to be assumed. © 2016 Wiley Periodicals, Inc.

    Current conflicts in some regions of the world give rise to massive immigration waves. Consequently, some infections that had nearly disappeared in Europe nowadays re-emerge. They are related to the epidemiology of the refugees' origin, but also to the epidemiology of the country crossed during migration. Hygiene conditions, often precarious during the journey, favor their transmission. Thus, cases of louse borne relapsing fever and diphtheria emerge in Europe and in Switzerland since 2074 whereas cutaneous Panton-Valen tine Staphylococcus aureus infection are more commonly observed nowadays.

    Starclose (Abbott Vascular Devices, Redwood City, CA) is a new arterial closure device that seals a femoral puncture site with an extravascular star-shaped nitinol clip. The clip projects small tines into the arterial wall which fold inward, causing the arterial wall to pucker, producing a purse-string-like seal closing the puncture site. The case history is that of a 76-year-old female patient who underwent day-case percutaneous diagnostic coronary angiography. A Starclose femoral artery closure device was used to achieve hemostasis with subsequent femoral artery stenosis.

It is common in areas where people are socioeconomically deprived. Globally, approximately 1.2 billion people live in trachoma-endemic areas, in which, 40.6 million individuals have active trachoma and 8.2 million have trichiasis. According to the World Health Organization’s 2007 report, globally close to 1.3 million people are blind due to trachoma, while approximately 84 million suffer from active trachoma. The National Survey (2007 of Ethiopia showed a prevalence of 40.1% active trachoma among children aged 1–9 years. Trachoma is still endemic in most parts of Ethiopia.Objective: To assess prevalence of trachoma and factors associated with it among children aged 1–9 years in Zala district, Gamo Gofa Zone, Southern Nations, Nationalities, and Peoples’ Region.Methods: A community-based cross-sectional study was conducted in Zala district from February 28 to March 26, 2014. A total of 611 children were examined for trachoma based on the simplified World Health Organization 1983 classification. A multistage stratified sampling technique with a systematic random sampling technique was used to select study participants. Data were collected by using a semistructured pretested questionnaire and clinical eye examination. The data were entered using EpiData version 3.1 and analyzed using SPSS version 16.

    Meinzinger, Franziska

    2010-07-01

    Within the framework of sustainable development it is important to find ways of reducing natural resource consumption and to change towards closed-loop management. As in many other spheres increased resource efficiency has also become an important issue in sanitation. Particularly nutrient recovery for agriculture, increased energy-efficiency and saving of natural water resources, can make a contribution to more resource efficient sanitation systems. To assess the resource efficiency of alternative developments a systems perspective is required. The present study applies a combined cost, energy and material flow analysis (ceMFA) as a system analysis method to assess the resource efficiency of urban sanitation systems. This includes the discussion of relevant criteria and assessment methods. The main focus of this thesis is the comparative assessment of different systems, based on two case studies; Hamburg in Germany and Arba Minch in Ethiopia. A range of possible system developments including source separation (e.g. diversion of urine or blackwater) is defined and compared with the current situation as a reference system. The assessment is carried out using computer simulations based on model equations. The model equations not only integrate mass and nutrient flows, but also the energy and cost balances of the different systems. In order to assess the impact of different assumptions and calculation parameters, sensitivity analyses and parameter variations complete the calculations. Based on the simulations, following general conclusions can be drawn: None of the systems show an overall benefit with regard to all investigated criteria, namely nutrients, energy, water and costs.

    Globally about one third of the total population is estimated to be infected with intestinal parasites, of which, the majority are people living in tropical and sub-tropical parts of the world. Cases of intestinal parasitosis are also highly abundant in Ethiopia and hence the aim of present study was to assess prevalence and predictors of intestinal parasitic infections among food handlers working in Arba Minch University students' cafeteria, South Ethiopia. A cross sectional study was conducted among food handlers working in Arba Minch University from April to June, 2015. A pretested structured questionnaire was used for collecting data about socio-demographic characteristics and possible risk factors. Stool specimens were collected and examined microscopically for the presence of eggs, cysts and trophozoites of intestinal parasites. Data entry and analysis were done using SPSS version 20 software. A total of 376 food handlers were enrolled in the study of which thirty one of them were not willing to participate for a stool examination. The majority of study participants were females 273 (72.6 %). About 123 (36 %) of food handlers were found to be positive for different intestinal parasites with the most abundant parasite of Entamoeba histolytica/dispar 48 (14 %) followed by Ascaris lumbricoides 32 (9.27 %). Finger nail status (AOR: 2.2, 95 % CI: 1.29-3.72), hand washing practice after toilet (AOR: 1.71, 95 % CI: 1.06-2.77), hand washing practice before food handling (AOR: 1.69, 95 % CI: 1.04-2.75), preparing food when suffering from diseases (AOR: 3.08, 95 % CI: 1.17-8.13), and using common knife for cutting raw flesh food and other food (AOR: 1.72, 95 % CI: 1.01-2.92) were independent predictors of intestinal parasitic infection among the food handlers. This study revealed a high prevalence of intestinal parasites among food handlers. Since most of the intestinal parasites are transmitted by the feco-oral route, food handlers could be an important source of

Providing psychosocial support and equipping orphans play a vital role in their lifes. A cross-sectional study was conducted on 7–18-year-old orphans at 17 local districts of Gamo Gofa Zone, Southern Regional State of Ethiopia. From a total of 48,270 orphans in these areas, 4,368 were selected using stratified simple random sampling technique. Data were collected with a designed questionnaire based on the Rosenberg's rating scale to measure their self-esteem levels. Self-esteem with a score less than or equal to an average score was considered to be low self-esteem in the analysis. Binary logistic regression model was used to analyze the data using the SPSS software. The results of the study revealed that the probability of orphans suffering from low self-esteem was 0.59. Several risk factors were found to be significant at the level of 5%. Psychosocial support (good guidance, counseling and treatment, physical protection and amount of love shared, financial and material support, and fellowship with other children, parents living together before death, strong relationship between parents before death, high average monthly income, voluntary support, and consideration from the society are some of the factors that decrease the risk of being low in self-esteem. There are many orphans with low self-esteem in the study areas. The factors negatively affecting the self-esteem of orphans include the lack of psychosocial support, poor social life of parents, and death of parents due to AIDS. Society and parents should be aware of the consequences of these factors which can influence their children's future self

    This essay analyses John Cleland’s Memoirs of a Coxcomb (1751), his idiosyncratic sequel to the more famous Memoirs of a Woman of Pleasure (1749). As Kathleen Lubey has recently shown, sensuality was part of literature’s repertoire of moral refinement. Indeed, Lubey has argued that erotica acts as ‘a continuous unfolding of epistemology from the details of amorous scenes’, providing a key means of understanding the self and its relation to the world. Yet despite its amorous plot, Memoirs of a...

    Australia has a long history of uranium mining. Most of the early production came from Rum Jungle in the Northern Territory and Mary Kathleen in Queensland. The second generation of uranium mines (Ranger, Nabarlek and Olympic Dam) came on line in the 1970s and 1980s at a time of increased environmental awareness and public scrutiny. The waste management practices at these mines are in accordance with best practicable technology for the uranium mining industry. This paper describes Australia's experience in managing the front end of the fuel cycle; uranium mining and ore processing. (orig.)

  15. Simulation of neuro-fuzzy model for optimization of combine header setting

    Full Text Available Introduction The noticeable proportion of producing wheat losses occur during production and consumption steps and the loss due to harvesting with combine harvester is regarded as one of the main factors. A grain combines harvester consists of different sets of equipment and one of the most important parts is the header which comprises more than 50% of the entire harvesting losses. Some researchers have presented regression equation to estimate grain loss of combine harvester. The results of their study indicated that grain moisture content, reel index, cutter bar speed, service life of cutter bar, tine spacing, tine clearance over cutter bar, stem length were the major parameters affecting the losses. On the other hand, there are several researchswhich have used the variety of artificial intelligence methods in the different aspects of combine harvester. In neuro-fuzzy control systems, membership functions and if-then rules were defined through neural networks. Sugeno- type fuzzy inference model was applied to generate fuzzy rules from a given input-output data set due to its less time-consuming and mathematically tractable defuzzification operation for sample data-based fuzzy modeling. In this study, neuro-fuzzy model was applied to develop forecasting models which can predict the combine header loss for each set of the header parameter adjustments related to site-specific information and therefore can minimize the header loss. Materials and Methods The field experiment was conducted during the harvesting season of 2011 at the research station of the Faulty of Agriculture, Shiraz University, Shiraz, Iran. The wheat field (CV. Shiraz was harvested with a Claas Lexion-510 combine harvester. The factors which were selected as main factors influenced the header performance were three levels of reel index (RI (forward speed of combine harvester divided by peripheral speed of reel (1, 1.2, 1.5, three levels of cutting height (CH(25, 30, 35 cm, three

    Fixation of the pacemaker leads during pacemaker implantation leads to an increase of cardiac Troponin T (cTnT) that can be interpreted as a sign of minimal myocardial damage. This trial evaluates whether the mechanism type of lead fixation influences the magnitude of cTnT release. Patients having a de-novo cardiac pacemaker implantation or a lead revision were centrally randomized to receive either a ventricular lead with an active (screw) or passive (tine) fixation mechanism. High-sensitive Troponin T (hsTnT) was determined on the day of the procedure beforehand and on the following day. 326 Patients (median age (IQR) 75.0 (69.0-80.0) years, 64% male) from six international centers were randomized to receive ventricular leads with an active (n = 166) or passive (n = 160) fixation mechanism. Median (IQR) hsTnT levels increased by 0.009 (0.004-0.021) ng/ml in the group receiving screw-in ventricular leads and by 0.008 (0.003-0.030) ng/ml in the group receiving tined ventricular leads (n.s.). In conclusion pacemaker implantations are followed by a release of hsTnT. The choice between active or passive fixation ventricular leads does not have a significant influence on the extent of myocardial injury and the magnitude of hsTnT release.

    2015-03-30

    Non-chemical weed control methods need to be directed towards a site-specific weeding approach, in order to be able to compete the conventional herbicide equivalents. A system for online weed control was developed. It automatically adjusts the tine angle of a harrow and creates different levels of intensity: from gentle to aggressive. Two experimental plots in a maize field were harrowed with two consecutive passes. The plots presented from low to high weed infestation levels. Discriminant capabilities of an ultrasonic sensor were used to determine the crop and weed variability of the field. A controlling unit used ultrasonic readings to adjust the tine angle, producing an appropriate harrowing intensity. Thus, areas with high crop and weed densities were more aggressively harrowed, while areas with lower densities were cultivated with a gentler treatment; areas with very low densities or without weeds were not treated. Although the weed development was relatively advanced and the soil surface was hard, the weed control achieved by the system reached an average of 51% (20%-91%), without causing significant crop damage as a result of harrowing. This system is proposed as a relatively low cost, online, and real-time automatic harrow that improves the weed control efficacy, reduces energy consumption, and avoids the usage of herbicide.

  20. Workshop Engages PCs in Accelerator Controls

    International Nuclear Information System (INIS)

    Matthew Bickley

    2006-01-01

    To discuss the rapidly growing and changing use of personal computers (PCs) in accelerator control systems, 80 accelerator controls specialists from 26 institutions in North America, Europe and Asia attended the 6. International Workshop on Personal Computers and Particle Accelerator Controls, PCaPAC2006, held October 24-27 at Jefferson Lab in Newport News, Virginia. PCs have become increasingly applicable to the control of accelerators as their computing capacities have increased exponentially over the last 10 years. Capabilities that once required the power available only from expensive, small-market systems offered by DEC, Sun or IBM can now be obtained with commodity hardware offered by many vendors. The price/performance ratio presented by any standard PC makes a compelling case for using PC hardware in accelerator controls wherever possible. The PCaPAC meeting underscored the importance of collaborative control system development. Several talks focused on additions to three such systems, TINE, TANGO and EPICS. The diverse contributions to these toolkits, both in content and source, demonstrate the power of leveraged software development across a number of facilities. TINE originated in DESY's desire to give users a unified software bus above disparate underlying platforms. TINE discussions at PCaPAC centered on the toolkit's interface layers, including address redirection and integration with other control systems. TANGO has been a collaborative effort from its inception. Based on CORBA, this open-source controls toolkit is a registered project in the source forge system. The workshop TANGO presentation discussed contributions from four TANGO institutions, and mentioned a broad range of new tools, from user interface applications to code generators and database integration software. EPICS, which was started at LANL in the 1980s, includes contributions from dozens of institutions around the world. EPICS-related PCaPAC discussions included virtual machines at

At the time T1 winter wheat was at tillering and weeds were at the cotyledons-2 true leaves growth stage. The experimental design was a randomized block with four replicates. Six weeks after mechanical treatments, weed ground cover (% was rated visually using the Braun-Blanquet coverabundance scale; weeds on three squares (0.6×0.5 m each one per plot were collected, counted, weighed, dried in oven at 105°C to determine weed density and weed above-ground dry biomass. At harvest, wheat ears density, grain yield, weight of 1000 seeds and hectolitre weight were recorded. Total weed flora was quite different in the three experiments.

    1984-01-01

    Several chemical and physical parameters are measured in forty seven stations, distributed on the most part of the hydrographic systems of Tunisia. Some parameters: temperature of the water (T), salinity (S, electric conductivity (CE), chloride (Cl-), total hardness (DT) and turbidity (TUR) show great variations in the Northern hydrographic systems. In these systems, the parameters (S, CE, Cl-, DT) are generally elevated in the tributaries of the south bank of the Medjerda, the North-East streams, Melah and Tine Streams which flow in the Ichkeul lake. The waters in these septentrional systems are sometimes very turbid. The waters of the meridional hydrological system are very clear. The resurgence thermal waters are characterized by the small amplitude of variations of the studied parameters.

    We will start by giving two answers to a single question, 'Why hydrogen?' We will follow this with a brief discussion of the energy system architecture's five-link chain, to emphasize the key role of the central link, energy currencies. Then, gluing these two concepts together - (a) systemic architecture and (b) the answer to why hydrogen - we can set out the rationale leading to the premise that our system will ultimately be dominated by the twin currencies, hydrogen and electricity. All this will serve as a foundation for considering the sources, infrastructures and service technologies likely to characterise the deeper future (2100 ∼ 2200). Finally, based on this long view (and our sliver of tine within it) we can use the perspective to suggest near-term strategies. (author)

    Full Text Available Strip-till save costs by reducing tillage on the area of sugar beet rows only. The seeding system is characterized by a deep loosening of soil with a tine combined with a share and by following tools generating fine-grained soil as seed bed. In cooperation with the Kverneland company group Soest/Germany a strip tiller combined with precision seeder was designed and tested in field experiments. Tilling and seeding was performed in one path on fields with straw and mustard mulch. Even the plant development was slower as compared to conventional sawn sugar beets the yield was on equivalent level. Further field experiments are planned to attest constant yield, cost and energy efficiency of the seeding system.

    Tillage methods and crop rotation are probably the two most important cropping factors affecting weed communities, particularly when herbicide use is restricted. This study examined weed dynamics following eleven years of different tillage and crop rotation treatments. The aboveground grass weed...... flora was recorded each year and the content and vertical location of individual weed seeds within the plough layer (0–20 cm) were determined after 11 years of continuous mouldboard ploughing (P), pre-sowing tine cultivation to 8–10 cm soil depth (H8-10) and direct drilling (D). The content of weed...... seeds, especially grass weeds, was determined for three distinct soil layers (0–5, 5–10 and 10–20 cm), reflecting the cultivation depths of the tillage treatments. The annual grass weeds, Apera spica-venti and Vulpia myuros, were promoted by non-inversion tillage and in the case of V. myuros also...

    The discovery of uniform latex particles by polymer chemists of the Dow Chemical Company nearly 50 years ago opened up new exciting fields for scientists and physicians and established many new biomedical applications. Many in vitro diagnostic tests such as the latex agglutination tests, analytical cell and phagocytosis tests have since become rou­ tine. They were all developed on the basis of small particles bound to biological active molecules and fluorescent and radioactive markers. Further developments are ongoing, with the focus now shifted to applications of polymer particles in the controlled and di­ rected transport of drugs in living systems. Four important factors make microspheres interesting for in vivo applications: First, biocompatible polymer particles can be used to transport known amounts of drug and re­ lease them in a controlled fashion. Second, particles can be made of materials which bio­ degrade in living organisms without doing any harm. Third, particles with modified surfaces are a...

    2007-01-01

    To accurately measure temperatures, a novel temperature sensor based on a quartz tuning fork resonator has been designed. The principle of the quartz tuning fork temperature sensor is that the resonant frequency of the quartz resonator changes with the variation in temperature. This type of tuning fork resonator has been designed with a new doubly rotated cut work at flexural vibration mode as temperature sensor. The characteristics of the temperature sensor were evaluated and the results sufficiently met the target of development for temperature sensor. The theoretical model for temperature sensing has been developed and built. The sensor structure was analysed by finite element method (FEM) and optimized, including tuning fork geometry, tine electrode pattern and the sensor's elements size. The performance curve of output versus measured temperature is given. The results from theoretical analysis and experiments indicate that the sensor's sensitivity can reach 60 ppm 0 C -1 with the measured temperature range varying from 0 to 100 0 C

    A graphene layer was synthesized using chemical vapor deposition methods and a polystyrene solution was spin-cast onto the graphene film. The graphene-polystyrene bilayer membrane was attached between the two tines of a microfabricated quartz tuning fork (QTF). The modulus of the graphene-polystyrene bilayer was measured to be twice that of a pristine polystyrene membrane. Exposure of the membrane-coated QTF to ethanol vapor decreased the resonance frequency of the microresonator. The bilayer membrane-coated QTF produced a frequency change that was three times the change obtained using a polystyrene membrane-coated QTF, with a lower degree of degradation in the Q factor. The limit of detection of the bilayer membrane-coated QTF to ethanol vapor was determined to be 20 ppm.

    The fatigue crack growth behavior of a cracked and patch-repaired Ah2024-T3 panel has been monitored by acoustic emission(AE). The overall crack growth rate was reduced The crack propagation into the adjacent hole was also retarded by introducing the patch repair. AE signals due to crack growth after the patch repair and those due to debonding of the plate-patch interface were discriminated by using the principal component analysis. The former showed high center frequency and low amplitude, whereas the latter showed long rise tine, low frequency and high amplitude. This type of AE signal recognition method could be effective for the prediction of fatigue crack growth behavior in the patch-repaired structures with the aid of AE source location

    Maximum allowable concentrations of 12 elements in uranium hexafluoride feed for enrichment to reactor grade material (about 3%), vary from 1 to 100 ppm ([mu]g/g). Using an inductively coupled plasma atomic emission spectrometer, 51 lines of tine of these elements (B, Cr, Mo, P, Sb, Si, Ta, Ti, V and W) has been studied with a uranium matrix to investigate the matrix interference on the basis of signal to background (SBR), and background to background ratios (BBR). Detection limits and limits of quantitative determination (LQDs) were calculated for these elements in a uranium matrix using SBR and relative standard deviation of the background signal (RSD[sub B]) approach. In almost all cases, the uranium matrix interference reduces the SBRs to the extent that direct trace analysis is impossible. A uranium sample having known concentrations of impurities (around LQDs) was directly analysed with results that showed reasonable accuracy and precision. (Author).

  6. The Technique for the Numerical Tolerances Estimations in the Construction of Compensated Accelerating Structures

    CERN Document Server

    Paramonov, V V

    2004-01-01

    The requirements to the cells manufacturing precision and tining in the multi-cells accelerating structures construction came from the required accelerating field uniformity, based on the beam dynamics demands. The standard deviation of the field distribution depends on accelerating and coupling modes frequencies deviations, stop-band width and coupling coefficient deviations. These deviations can be determined from 3D fields distribution for accelerating and coupling modes and the cells surface displacements. With modern software it can be done separately for every specified part of the cell surface. Finally, the cell surface displacements are defined from the cell dimensions deviations. This technique allows both to define qualitatively the critical regions and to optimize quantitatively the tolerances definition.

    Abstract Soil application of organic waste products (OWP) can maintain or increase soil organic carbon (SOC) content, which in turn could lead to increased porosity and potentially to reduced energy use for soil tillage. Only a few studies have addressed the effect of SOC content on draught force...... for soil tillage, and this still needs to be addressed for fields that receive diverse types of organic waste of urban, agricultural and agro-industrial origin. The objective of this study was to determine the effect of changes in SOC induced by repeated soil application of OWP on draught force for soil...... tillage and tractor fuel consumption. Draught force was measured for tillage with conventional spring tillage tines, as well as bulk density, soil texture and SOC content in the CRUCIAL field experiment, Denmark in which diverse types of OWP had been applied annually for 11 years. The OWP included...

    2015-01-01

    A method to form high quality electrostatically guided lepton beams is explored. Test electron beams are extracted from tailored plasmas confined in a Penning-Malmberg trap. The particles are then extracted from the confining axial magnetic field by passing them through a high magnetic permeability grid with radial tines (a so-called “magnetic spider”). An Einzel lens is used to focus and analyze the beam properties. Numerical simulations are used to model non-adiabatic effects due to the spider, and the predictions are compared with the experimental results. Improvements in beam quality are discussed relative to the use of a hole in a high permeability shield (i.e., in lieu of the spider), and areas for further improvement are described

  11. Mechanical weed control on small-size dry bean and its response to cross-flaming

    Dry bean (Phaseolus vulgaris L.) can be a profitable crop for farmers; however controlling weeds effectively without a decrease in yield remains a problem. An example where mechanical weed control is difficult to conduct is dry bean ‘Toscanello’, which is a small sized high-income niche product growing low to the ground. Concerning intra-row weed control, also flame weeding could be an opportunity but the dry bean heat tolerance needs to be studied. The aims of this research were to study the weed control efficacy of a spring-tine harrow and an inter-row cultivator in this bean variety, and to test the tolerance of dry bean cultivated under weed-free conditions to cross-flaming applied with different liquefied petroleum gas (LPG) doses. Flame weeding was applied at BBCH 13 and BBCH 14 bean growth stages by pairs of burners producing direct double flame acting into the intra-row space, with bean plants placed in the middle. The results suggest that the spring-tine harrow used two times at BBCH 13 and 14, respectively, lead to a yield similar to that of the weedy control. The inter-row cultivator could be an opportunity for small-sized dry bean crops producers, enabling them to obtain a similar yield compared to the hand-weeded control. Concerning the bean tolerance to cross-flaming the results showed that bean flamed at BBCH 13 stage had little tolerance to cross-flaming. Bean flamed at BBCH 14 stage was tolerant until an LPG dose of 39 kg/ha, giving yield responses similar to those observed in the non-flamed control. (Author)

    2013-01-01

    Harrowing is often used to reduce weed competition, generally using a constant intensity across a whole field. The efficacy of weed harrowing in wheat and barley can be optimized, if site-specific conditions of soil, weed infestation and crop growth stage are taken into account. This study aimed to develop and test an algorithm to automatically adjust the harrowing intensity by varying the tine angle and number of passes. The field variability of crop leaf cover, weed density and soil density was acquired with geo-referenced sensors to investigate the harrowing selectivity and crop recovery. Crop leaf cover and weed density were assessed using bispectral cameras through differential images analysis. The draught force of the soil opposite to the direction of travel was measured with electronic load cell sensor connected to a rigid tine mounted in front of the harrow. Optimal harrowing intensity levels were derived in previously implemented experiments, based on the weed control efficacy and yield gain. The assessments of crop leaf cover, weed density and soil density were combined via rules with the aforementioned optimal intensities, in a linguistic fuzzy inference system (LFIS). The system was evaluated in two field experiments that compared constant intensities with variable intensities inferred by the system. A higher weed density reduction could be achieved when the harrowing intensity was not kept constant along the cultivated plot. Varying the intensity tended to reduce the crop leaf cover, though slightly improving crop yield. A real-time intensity adjustment with this system is achievable, if the cameras are attached in the front and at the rear or sides of the harrow. PMID:23669712

    Full Text Available Harrowing is often used to reduce weed competition, generally using a constant intensity across a whole field. The efficacy of weed harrowing in wheat and barley can be optimized, if site-specific conditions of soil, weed infestation and crop growth stage are taken into account. This study aimed to develop and test an algorithm to automatically adjust the harrowing intensity by varying the tine angle and number of passes. The field variability of crop leaf cover, weed density and soil density was acquired with geo-referenced sensors to investigate the harrowing selectivity and crop recovery. Crop leaf cover and weed density were assessed using bispectral cameras through differential images analysis. The draught force of the soil opposite to the direction of travel was measured with electronic load cell sensor connected to a rigid tine mounted in front of the harrow. Optimal harrowing intensity levels were derived in previously implemented experiments, based on the weed control efficacy and yield gain. The assessments of crop leaf cover, weed density and soil density were combined via rules with the aforementioned optimal intensities, in a linguistic fuzzy inference system (LFIS. The system was evaluated in two field experiments that compared constant intensities with variable intensities inferred by the system. A higher weed density reduction could be achieved when the harrowing intensity was not kept constant along the cultivated plot. Varying the intensity tended to reduce the crop leaf cover, though slightly improving crop yield. A real-time intensity adjustment with this system is achievable, if the cameras are attached in the front and at the rear or sides of the harrow.

    Colonies of Glossina fuscipes fuscipes Newstead and Glossina pallidipes Austen (origin Tororo) were established at Kaliti Center by acquiring pupae from Bratislava, Slovakia. The main objectives of the introduction of these species were to strengthen the release activities in the adjacent area where G. f. fuscipes exists, and to establish a back-up for the Arba Minch strain of G. pallidipes. Since April 2008, 20 300 G. f. fuscipes and 5300 G. pallidipes pupae were delivered to Kaliti. In week 38 the tsetse fly colony of G. f. fuscipes reached 14 800 females, and that of G. pallidipes reached 1500. The physical holding conditions for both species were 24{+-}1{sup o}C and 80-85% RH. The flies were kept in PVC cages at a density of 60 females/cage for G. f. fuscipes and 48 females/cage for G. pallidipes, with a male to female ratio of 1:4. They were fed 5 days per week on whole defibrinated bovine blood that was collected aseptically and irradiated at 0.5-1.5 kGy before storage at -20{sup o}C. The blood was presented to the flies through a silicone membrane at 35-37{sup o}C. Females of G. f. fuscipes, when 3 days old, were mated with 7 days old males, and females of G. pallidipes, when 7 days old, were mated with 10-12 days old males. The establishment of these two species was monitored by measuring regularly the following parameters: pupal production, pupal weight, emergence rate, PPIF, P/F/10 days and daily mortality. (author)

  15. When gender matters: new insights into the relationships between social systems and the genetic structure of human populations.

    Due to its important effects on the ecological dynamics and the genetic structure of species, biologists have long been interested in gender-biased dispersal, a condition where one gender is more prone to move from the natal site. More recently, this topic has attracted a great attention from human evolutionary geneticists. Considering the close relations between residential rules and social structure, gender-biased dispersal is, in fact, regarded as an important case study concerning the effects of socio-cultural factors on human genetic variation. It all started with the seminal paper by Mark Seielstad, Erich Minch and Luigi Luca Cavalli Sforza from Stanford University (Seielstad et al. 1998). They observed a larger differentiation for Y-chromosome than mitochondrial DNA between extant human populations, purportedly a consequence of the prevalence of long-term patrilocality in human societies. Subsequent studies, however, have highlighted the need to consider geographically close and culturally homogeneous groups, disentangle signals due to different peopling events and obtain unbiased estimates of genetic diversity. In this issue of Molecular Ecology, not only do Marks et al. (2012) adopt an experimental design which addresses these concerns, but they also take a further and important step forward by integrating the genetic analysis of two distant populations, the Basotho and Spanish, with data regarding migration rates and matrimonial distances. Using both empirical evidence and simulations, the authors show that female-biased migration due to patrilocality might shape the genetic structure of human populations only at short ranges and under substantial differences in migration rates between genders. Providing a quantitative framework for future studies of the effects of residential rules on the human genome, this study paves the way for further developments in the field. On a wider perspective, Marks et al.'s work demonstrates the power of approaches which

    Risky sexual behavior (RSB) and its consequence among school adolescents and youths have been well understood. It is still a common practice among college and university students living away from their controlling families compounded with the ever-worsening khat chewing habits. However, the relation between khat chewing and RSB is not well studied particularly among college students in Ethiopia. Hence, this study contributes to the literature by examining disparities of RSB among khat chewer and non-chewer students in Southern Ethiopia with the purpose of improving adolescent and youth health. An institution-based comparative cross-sectional study was conducted among 1211 college students at Arba Minch town in March 2015. Respondents were selected by employing a simple random sampling technique. Data was collected by using a pre-tested, structured, self- administered questionnaire. The data was entered into Epidata version 3.1 and analyzed using IBM SPSS statistics version 21. Level of statistical significance was declared at a p- value of pornographic movies (AOR = 2.51, 95% CI = 1.79,3.51), khat chewing (AOR = 3.02, 95% CI:=1.91,4.76) and alcohol drinking (AOR = 2.26, 95% CI = 1.54,3.35) were factors associated with RSB. Considerable proportions of students were engaged in khat chewing and RSB. RSB was significantly higher among khat chewers as compared to non- chewers. Comprehensive sexuality education was recommended to college communities and by extension to the ministry of health and education to address the identified factors so that RSB can be reshaped.

    Polyhydroxybutyrates (PHBs) are macromolecules synthesized by bacteria. They are inclusion bodies accumulated as reserve materials when the bacteria grow under different stress conditions. Because of their fast degradability under natural environmental conditions, PHBs are selected as alternatives for production of biodegradable plastics. The aim of this work was to isolate potential PHB producing bacteria, evaluate PHB production using agro-residues as carbon sources. Among fifty bacterial strains isolated from different localities, ten PHB accumulating strains were selected and compared for their ability to accumulate PHB granules inside their cells. Isolate Arba Minch Waste Water (AWW) identified as Bacillus spp was found to be the best producer. The optimum pH, temperature, and incubation period for best PHB production by the isolate were 7, 37 °C, and 48 h respectively at 150 rpm. PHB production was best with glucose as carbon source and peptone as nitrogen source. The strain was able to accumulate 55.6, 51.6, 37.4 and 25% PHB when pretreated sugar cane bagasse, corn cob, teff straw (Eragrostis tef) and banana peel were used as carbon sources respectively. Fourier transform-infrared authentication results of the extracted and purified PHB identified its functional units as C-H, CH 2 , C=O and C-O groups. UV-Vis spectrophotometric analysis and biodegradability test confirmed the similarity of the extract with standard PHB and its suitability for bioplastic production. The isolated Bacillus sp can be used for feasible production of PHB using agro-residues especially sugarcane bagasse which can reduce the production cost in addition to reducing the disposal problem of these substrates. The yield of PHB can further be boosted by optimization of production parameters as substrates.

    Full Text Available Abstract Background As the resource implications of expanding anti-retroviral therapy (ART are likely to be large, there is a need to explore its cost-effectiveness. So far, there is no such information available from Ethiopia. Objective To assess the cost-effectiveness of ART for routine clinical practice in a district hospital setting in Ethiopia. Methods We estimated the unit cost of HIV-related care from the 2004/5 fiscal year expenditure of Arba Minch Hospital in southern Ethiopia. We estimated outpatient and inpatient service use from HIV-infected patients who received care and treatment at the hospital between January 2003 and March 2006. We measured the health effect as life years gained (LYG for patients receiving ART compared with those not receiving such treatment. The study adopted a health care provider perspective and included both direct and overhead costs. We used Markov model to estimate the lifetime costs, health benefits and cost-effectiveness of ART. Findings ART yielded an undiscounted 9.4 years expected survival, and resulted in 7.1 extra LYG compared to patients not receiving ART. The lifetime incremental cost is US$2,215 and the undiscounted incremental cost per LYG is US$314. When discounted at 3%, the additional LYG decreases to 5.5 years and the incremental cost per LYG increases to US$325. Conclusion The undiscounted and discounted incremental costs per LYG from introducing ART were less than the per capita GDP threshold at the base year. Thus, ART could be regarded as cost-effective in a district hospital setting in Ethiopia.

    Full Text Available In this paper, I will explore and extend the concept of presence as formulated by the Dutch philosopher of history, novelist and psychologist Eelco Runia, arguing that it provides a useful tool with which to unpick some of the non-representational aspects of exhibition making in historical museums. The paper proceeds from a  desire to find theoretical tools with which to, in Kathleen Stewarts words, ‘slow the quick jump to representational thinking and evaluative critique long enough to find ways of approaching the complex and uncertain objects that fascinate because they literally hit us or exert a pull on us’ (Stewart 2007: 4. Specifically, I will use a philosophical analysis of presence to show how it might be employed in a museum context, through the conceptual pairings of presence and meaning, discontinuity and continuity, and metaphor and metonymy.

  20. Planned obsolescence publishing, technology, and the future of the academy

    2011-01-01

    Academic institutions are facing a crisis in scholarly publishing at multiple levels: presses are stressed as never before, library budgets are squeezed, faculty are having difficulty publishing their work, and promotion and tenure committees are facing a range of new ways of working without a clear sense of how to understand and evaluate them. Planned Obsolescence is both a provocation to think more broadly about the academy’s future and an argument for reconceiving that future in more communally-oriented ways. Facing these issues head-on, Kathleen Fitzpatrick focuses on the technological changes—especially greater utilization of internet publication technologies, including digital archives, social networking tools, and multimedia—necessary to allow academic publishing to thrive into the future. But she goes further, insisting that the key issues that must be addressed are social and institutional in origin. Springing from original research as well as Fitzpatrick’s own hands-on experiments in ne...

    What motivates organizational leaders in their search for spirituality? They seek to integrate their inner journey with their day-to-day professional roles. This article describes how a course in spirituality for executives has provided tools to analyze and clarify intentions, avoid the traps of excessive greed and power, and make decisions that are both compassionate and effective. André L. Delbecq, DBA, the Thomas J. and Kathleen L. McCarthy Professor at the Leavey School of Business at Santa Clara University in California, offers seminars in spirituality for organizational leadership through the MBA program and the Center for Executive Development. Delbecq is the first to admit his surprise at the number of executives who have repeatedly asked for courses in spirituality. He talks about how his seminars have helped CEOs and other top executives achieve greater effectiveness in leading organizations.

    Little is known about the process of psychosocial adaptation to familial risk in tested and untested individuals at increased familial risk of cancer. This paper presents findings from a qualitative study of 36 women participating in the Kathleen Cuningham Consortium for Research into Familial Breast cancer (kConFab) Psychosocial study. Facilitators and challenges in psychosocial adaptation were identified through semi-structured interviews. The women, who were either tested (carriers or non-carriers of breast cancer susceptibility mutations) or untested (ineligible for testing or eligible but delayed or declined testing), described personal, support network and healthcare characteristics that impacted on the adaptation process. Challenges in one domain could be overcome by facilitators in other domains and key differences relating to whether women had undergone testing, or not, were identified. Tested and untested women with an increased familial risk of breast cancer may benefit from support tailored to their mutation testing status in order to enhance adaptation.

    This article uses a 1903 text by the Irish cookery instructress Kathleen Ferguson to examine the intersections between food, medicine and domestic work. Sick Room Cookery, and numerous texts like it, drew on traditions of domestic medicine and Anglo-Irish gastronomy while also seeking to establish female expertise informed by modern science and medicine. Placing the text in its broader cultural context, the article examines how it fit into the tradition of domestic medicine and the emerging profession of domestic science. Giving equal weight to the history of food and of medicine, and seeing each as shaped by historical context, help us to see the practice of feeding the sick in a different way.

Abstract: Translocations of the endangered red-cockaded woodpecker have been conducted since 1986 to enhance critically small subpopulations, to minimize the likelihood of local extirpations, and to reduce the adverse effects of fragmentation and isolation among existing populations. Such attempts have had mixed success. This article compares "hard" releases with a "soft" release technique where the birds are temporarily interned in a large aviary at the release point for a period of 9 to 14 days.

Abstract: I constructed a foraging study to examine habitat use of red-cockaded woodpeckers at the Savannah River Site, South Carolina. Because much of the land had been harvested in the late 1940s and early 1950s prior to being sold to the Department of Energy, the available habitat largely consisted of younger trees (e.g., less than 40 years old). From 1992 to 1995, I examined the foraging behavior and reproductive success of 7 groups of red-cockaded woodpeckers.

    Australia is one of the richest countries as far as uranium is concerned. The Jabiluka deposit alone is considered to be the largest single uranium deposit of the Western world. The overall known assured uranium reserves in Australia amount to 465.000 tons U 3 O 8 at cost ranges between 15 and 30 US Dollar per pound U 3 O 8 , i.e. approximately 21% of the known world reserves. Most of the Australien uranium ore is of relatively high grade and nearly all of it could be mined from open pit. At this stage Mary Kathleen in Queensland is the only producing uranium mine in Australia. The actual political attitude of the Australian government prevents the Australian uranium industry from beeing further developed. (orig.) 891 HP/orig. 892 MKO [de

    The history of the discovery of Australia's uranium deposits is reviewed. The exploration can be conveniently divided into three periods - pre-1944, when the only significant discoveries were made by prospectors in South Australia at Radium Hill and Mount Painter; 1944-1960 and post-1967. The second period saw uranium discoveries in the Northern Territory and Queensland, most of which were made by prospectors using hand-held geiger counters and rewarded by the Australian Government. Since 1967 new deposits have been found in the Northern Territory, Queensland, South Australia and Western Australia by companies using maps, airborne radiometric surveys and sophisticated equipment. The step from the discovery of Mary Kathleen by prospectors to finding Roxby Downs by a combination of geophysical methods, geological concepts and deep drilling was a very big one

    1988-01-01

    Geologic, photographic, and remote sensing data on Rima Mozart are analyzed to study the processes responsible for the formation of lunar sinuous rilles. The results show that it is unlikely that a complete lava tube could have existed along the Rima Mozart rille. A total eruptive volume of 6372 cu km has been determined for an open channel or tube with an eruption rate of about 80,000 cu m/s and a duration of 947 days. Near-infrared spectral reflectance data and 2.8-cm and 70-cm radar observations indicate that volcanic activity was responsible for the formation of the rille and that pyroclastic deposits are present around Kathleen and Ann as well as at the base of the Apennines.

    Full Text Available I do not understand painting very well, and especially not Australian Indigenous painting, the dot painting of Western and Central Desert artists such as Kathleen Petyarre. I grew up without art on the wall, among gum trees, red dirt, dying wattle, and ‘two thirds (blue sky’. While this might suggest that I inhabit the same landscape as Petyarre, I also grew up without ‘the Dreaming’, the meaning that this dot painting is said to be about. How and why then can this painting have the impact on me that it does? And, given the history of colonisation in Australia, including the colonisation of Indigenous meanings, what is the politics of the impact of that painting?

  12. Estimating insured residential losses from large flood scenarios on the Tone River, Japan - a data integration approach

    2011-12-01

    Flooding on the Tone River, which drains the largest catchment area in Japan and is now home to 12 million people, poses significant risk to the Greater Tokyo Area. In April 2010, an expert panel in Japan, the Central Disaster Prevention Council, examined the potential for large-scale flooding and outlined possible mitigation measures in the Greater Tokyo Area. One of the scenarios considered closely mimics the pattern of flooding that occurred with the passage of Typhoon Kathleen in 1947 and would potentially flood some 680 000 households above floor level. Building upon that report, this study presents a Geographical Information System (GIS)-based data integration approach to estimate the insurance losses for residential buildings and contents as just one component of the potential financial cost. Using a range of publicly available data - census information, location reference data, insurance market information and flood water elevation data - this analysis finds that insurance losses for residential property alone could reach approximately 1 trillion JPY (US 12.5 billion). Total insurance losses, including commercial and industrial lines of business, are likely to be at least double this figure with total economic costs being much greater again. The results are sensitive to the flood scenario assumed, position of levee failures, local flood depths and extents, population and building heights. The Average Recurrence Interval (ARI) of the rainfall following Typhoon Kathleen has been estimated to be on the order of 200 yr; however, at this juncture it is not possible to put an ARI on the modelled loss since we cannot know the relative or joint probability of the different flooding scenarios. It is possible that more than one of these scenarios could occur simultaneously or that levee failure at one point might lower water levels downstream and avoid a failure at all other points. In addition to insurance applications, spatial analyses like that presented here have

    In order to better understand the processes responsible for the formation of lunar sinuous rilles, a study of Rima Mozart was conducted using a variety of geologic, photographic, and remote sensing data. The apparent source of this rille is located in a highlands unit of known composition and it is hypothesized that thermal and mechanical erosion played an important role in the formation of Rima Mozart. Excellent photographic, topographic, multispectral, and radar data exist for this rille. The preliminary results of an analysis of this data are presented. Photographic data indicates the presence of two volcanic source vents for Rima Mozart: Kathleen and Ann. It is suggested that Rima Mozart, like many other lunar sinuous rilles, was most likely formed by a combination of events. Rima Mozart does follow a pre-existing, dominant NW/SE structural trend suggesting the influence of structural features on the rille, however, the tectonic influence is not the sole source for the formation of the rille, as suggested by the presence of the two source vents and the spatter around Ann. It is suggested that the rille formation began with an explosive eruption at Kathleen which later calmed down to a pulsating, high volume, low-viscosity lava flow. The rapid effusion rate of the magma as well as its high temperature and turbid nature helped carve the sinuous rille into the fractured and structurally weak Apennine Bench Formation underneath. Similar eruptions and subsequent flows were also created at Ann and joined to the main channel by a NE-trending secondary rille

    Four flavanones (pinostrobin, pinocembrin, sakuranetin and naringenin), one dihydroflavonol (7-methyl aromadendrin) and one flavone (hispidulin) have been isolated from Artemisia campestris L. ssp. glutinosa Gay and identified by spectroscopic methods. Artemisia campestris L. sous-espèce glutinosa Gay est une Composée Anthémidée largement répandue sur les sables du littoral méditerranéean et abondante dans certaines régions d'Espagne et d'Italie. Dans le cadre d'une étude chimiotaxonomique du genre Artemisia Tourn., nous nous sommes intéressés à l'analyse des flavonoïdes, composés jamais décrits, à notre connaissance, dans cette espèce d' Artemisia. Les sommités fleuries d' Artemisia campestris sous-espèce glutinosa, séchées et pulvérisées, sont dégraissées à l'ether de pétrole et épuisées par le chloroforme. Le fractionnement de l'extrait chloroformique, par chromatographie sur colonne de silice, et la purification de certaines fractions conduisent à l'isolement de six génines flavoniques, à l'etat pur. L' étude des spectres UV, des spectres de masse et des spectres de RMN [1,2] et la comparaison avec des échantillons authentiques permettent de proposer, pour ces flavonoïdes, les structures de la pinostrobine [3], de la pinocembrine [4], de la sakuranétine, de la naringénine [5] (flavanones), de la méthyl-7-aromadendrine, [6, 7] (dihydroflavonol) et de l'hispiduline [8, 9] (flavone); quatre de ces génines sont méthylées. Parmi ces flavonoïdes, la pinostrobine n'a jamais été décrite, à notre connaissance, dans la famille des Composées; la pinocembrine, la sakuranétine et la naringénine ont déjà été signalées chez quelques Astéracées et Eupatoriées [10], et l'hispiduline dans la tribu des Anthémidées ( Santolina chamaecyparissus L.)

    Complex regional pain syndrome (CRPS) is a debilitating painful disorder, cryptic in its pathophysiology and refractory condition with limited therapeutic options. Type I CRPS with its variable relationship to trauma has often no discernible fractures or nerve injuries and remains enigmatic in its response to conservative treatment as well as the other limited interventional therapies. Neuromodulation in the form of spinal cord and dorsal root ganglion stimulation (SCS, DRGS) has shown encouraging results, especially of causalgia or CRPS I of lower extremities. Upper extremity CRPS I is far more difficult. To report a case of upper extremity CRPS I treated by wireless peripheral nerve stimulation (WPNS) for its unique features and minimally invasive technique. The system does not involve implantation of battery or its connections. A 47 year old female patient presented with refractory CRPS I following a blunt trauma to her right forearm. As interventional treatment in the form of local anesthetics (Anesthesia of peripheral branches of radial nerve) and combined infusions of ketamine/lidocaine failed to provide any significant relief she opted for WPNS treatment. Based on the topographic distribution, two electrodes (Stimwave Leads: FR4A-RCV-A0 with tines, Generation 1 and FR4A-RCV-B0 with tines, Generation 1), were placed along the course of radial and median nerves under ultrasonography monitoring and guided by intraoperative stimulation. This procedure did not involve implantation of extension cables or the power source. At a frequency of 60 Hz and 300 μs the stimulation induced paresthesia along the distribution of the nerves. Therapeutic relief was observed with high frequency (HF) stimulation (HF 10 kHz/32 μs, 2.0 mA) reducing her pain from a visual analogue scale (VAS) score of 7-4 postoperatively. Three HF stimulations programs were provided at the time of discharge, as she improved in her sensory impairment to touch, pressure and temperature at her first

    Fluvial channels respond to changing tectonic and climatic conditions by adjusting their patterns of erosion and relief. It is therefore expected that by examining these patterns, we can infer the tectonic and climatic conditions that shaped the channels. However, the potential interference between climatic and tectonic signals complicates this inference. Within the framework of the stream power model that describes incision rate of mountainous bedrock rivers, climate variability has two effects: it influences the erosive power of the river, causing local slope change, and it changes the fluvial response time that controls the rate at which tectonically and climatically induced slope breaks are communicated upstream. Because of this dual role, the fluvial response time during continuous climate change has so far been elusive, which hinders our understanding of environmental signal propagation and preservation in the fluvial topography. An analytic solution of the stream power model during general tectonic and climatic histories gives rise to a new definition of the fluvial response time. The analytic solution offers accurate predictions for landscape evolution that are hard to achieve with classical numerical schemes and thus can be used to validate and evaluate the accuracy of numerical landscape evolution models. The analytic solution together with the new definition of the fluvial response time allow inferring either the tectonic history or the climatic history from river long profiles by using simple linear inversion schemes. Analytic study of landscape evolution during periodic climate change reveals that high frequency (10-100 kyr) climatic oscillations with respect to the response time, such as Milankovitch cycles, are not expected to leave significant fingerprints in the upstream reaches of fluvial channels. Linear inversion schemes are applied to the Tinee river tributaries in the southern French Alps, where tributary long profiles are used to recover the

    The Ethiopian epidemic is currently on the wane. However, the situation for infected children is in some ways lagging behind due to low treatment coverage and deficient prevention of mother-to-child transmission. Too few studies have examined HIV infected children presenting to care in low-income countries in general. Considering the presence of local variations in the nature of the epidemic a study in Ethiopia could be of special value for the continuing fight against HIV. The aim of this study is to describe the main characteristics of children with HIV presenting to care at a district hospital in a resource-limited area in southern Ethiopia. The aim was also to analyse factors affecting pre-ART loss to follow-up, time to ART-initiation and disease stage upon presentation. This was a prospective cohort study. The data analysed were collected in 2009 for the period January 2003 through December 2008 at Arba Minch Hospital and additional data on the ART-need in the region were obtained from official reports. The pre-ART loss to follow-up rate was 29.7%. Older children (10-14 years) presented in a later stage of their disease than younger children (76.9% vs. 45.0% in 0-4 year olds, chi-square test, χ2 = 8.8, P = 0.01). Older girls presented later than boys (100.0% vs. 57.1%, Fisher's exact test, P = 0.02). Children aged 0-4 years were more likely to be lost to follow-up (40.0 vs. 21.8%, chi-square test, χ2 = 5.4, P = 0.02) and had a longer time to initiate ART (Cox regression analysis, HR: 0.50, 95% CI: 0.25-0.97, P = 0.04, controlling for sex, place of residence, enrollment phase and WHO clinical stage upon presentation). Neither sex was overrepresented in the sample. Tuberculosis prevalence upon presentation and previous history of tubercolosis were 14.5% and 8% respectively. The loss to follow-up is alarmingly high and children present too late. Further research is needed to explore specific causes and possible solutions.

    Introduction Rural communities in low-income countries lack vital registrations to track birth outcomes. We aimed to examine the feasibility of community-based birth registration and measure maternal mortality ratio (MMR) in rural south Ethiopia. Methods In 2010, health extension workers (HEWs) registered births and maternal deaths among 421,639 people in three districts (Derashe, Bonke, and Arba Minch Zuria). One nurse-supervisor per district provided administrative and technical support to HEWs. The primary outcomes were the feasibility of registration of a high proportion of births and measuring MMR. The secondary outcome was the proportion of skilled birth attendance. We validated the completeness of the registry and the MMR by conducting a house-to-house survey in 15 randomly selected villages in Bonke. Results We registered 10,987 births (81·4% of expected 13,492 births) with annual crude birth rate of 32 per 1,000 population. The validation study showed that, of 2,401 births occurred in the surveyed households within eight months of the initiation of the registry, 71·6% (1,718) were registered with similar MMRs (474 vs. 439) between the registered and unregistered births.

  1. Estimating insured residential losses from large flood scenarios on the Tone River, Japan – a data integration approach

    Full Text Available Flooding on the Tone River, which drains the largest catchment area in Japan and is now home to 12 million people, poses significant risk to the Greater Tokyo Area. In April 2010, an expert panel in Japan, the Central Disaster Prevention Council, examined the potential for large-scale flooding and outlined possible mitigation measures in the Greater Tokyo Area. One of the scenarios considered closely mimics the pattern of flooding that occurred with the passage of Typhoon Kathleen in 1947 and would potentially flood some 680 000 households above floor level. Building upon that report, this study presents a Geographical Information System (GIS-based data integration approach to estimate the insurance losses for residential buildings and contents as just one component of the potential financial cost. Using a range of publicly available data – census information, location reference data, insurance market information and flood water elevation data – this analysis finds that insurance losses for residential property alone could reach approximately 1 trillion JPY (US$ 12.5 billion. Total insurance losses, including commercial and industrial lines of business, are likely to be at least double this figure with total economic costs being much greater again. The results are sensitive to the flood scenario assumed, position of levee failures, local flood depths and extents, population and building heights. The Average Recurrence Interval (ARI of the rainfall following Typhoon Kathleen has been estimated to be on the order of 200 yr; however, at this juncture it is not possible to put an ARI on the modelled loss since we cannot know the relative or joint probability of the different flooding scenarios. It is possible that more than one of these scenarios could occur simultaneously or that levee failure at one point might lower water levels downstream and avoid a failure at all other points. In addition to insurance applications, spatial analyses like

    Nano-science and nano-technology are rapidly developing scientific and technological areas that deal with physical, chemical and biological processes that occur on nano-meter scale – one millionth of a millimeter. Self-organization and pattern formation play crucial role on nano-scales and promise new, effective routes to control various nano-scales processes. This book contains lecture notes written by the lecturers of the NATO Advanced Study Institute "Self-Assembly, Pattern Formation and Growth Phenomena in Nano-Systems" that took place in St Etienne de Tinee, France, in the fall 2004. They give examples of self-organization phenomena on micro- and nano-scale as well as examples of the interplay between phenomena on nano- and macro-scales leading to complex behavior in various physical, chemical and biological systems. They discuss such fascinating nano-scale self-organization phenomena as self-assembly of quantum dots in thin solid films, pattern formation in liquid crystals caused by light, self-organi...

  3. Calvin’s modification of Augustine’s doctrine of original sin

    2010-07-01

    Full Text Available Augustine was Calvin’s main source of reference in the “Insti- tutes”. However, his treatment of Augustine’s views was not uncritical. This article discusses the way in which Calvin modi- fied Augustine’s doctrine of original sin. The main differences can be attributed to different theological aims. Augustine deve- loped his doctrine of original sin against the teachings of the Manicheans and Pelagians, whereas Calvin shifted the focus to knowledge of God and the self. Calvin understood original sin noetically as religious and moral blindness – whereas Augus- tine viewed sexual concupiscence as the main principle of original sin. Augustine made a considerable effort to explain that sin does not find its origin in God. God foresaw the fall, but did not compel it. Calvin located sin in God’s eternal decree and permission. Augustine, furthermore, understood the transmis- sion of original sin biologically, whereas Calvin ascribed it to God’s eternal permissive will. These differences culminated in a different understanding of the meaning of Jesus’ virgin birth. The article concludes by discussing the relevance of Calvin’s noetic approach to original sin.

    New species are described from the following genera: Consorophylax and Anisogamus, (Trichoptera, Limnephilidae). Additionally the larvae of the genus Anisogamus, and the larval stages of Anisogamus waringeri nov. sp. and A. difformis (McLachlan 1867) are described. The new species Consorophylax vinconi sp. nov. is a microendemic from the Southern Alps and differs distinctly from its congeners in the shape of the parameres, which are distinctly straitened in the distal quarter in the new species. The new species Anisogamus waringeri sp. nov. represents the second species in the hitherto monospecific genus Anisogamus. Compared to Anisogamus difformis, A. waringeri sp. nov. develops more slender superior appendages; a more rounded basal plate of the intermediate appendages, lacking pointed protuberances; and parameres shorter than the aedaegus, proximally with one dorsal and several ventral tines. Further, the two species are disjunctly distributed in the European mountain ranges (A. difformis: Alps, A. waringeri sp. nov.: Pyrenees). Larvae of the genus Anisogamus are characterized by the lack of a dorsal protuberance on the 1st abdominal segment, a unique feature among Limnephilidae. Anisogamus difformis and A. waringeri sp. nov. larvae differ in pronotum shape. The recovery of two new species demonstrates the significance of taxonomic studies in Europe, and the importance of adequate training for young scientists in order to assess a biodiversity under threat of extinction that has yet to be fully described.

    The aim of this research was to assess the possibility of conducting an absolute orientation procedure for video imagery, in which the external orientation for the first image was typical for aerial photogrammetry whereas the external orientation of the second was typical for terrestrial photogrammetry. Starting from the collinearity equations, assuming that the camera tilt angle is equal to 90°, a simplified mathematical model is proposed. The proposed method can be used to determine the X, Y, Z coordinates of points based on a set of collinearity equations of a pair of images. The use of simplified collinearity equations can considerably shorten the processing tine of image data from Unmanned Aerial Vehicles (UAVs), especially in low cost systems. The conducted experiments have shown that it is possible to carry out a complete photogrammetric project of an architectural structure using a camera tilted 85°–90° (φ or ω) and simplified collinearity equations. It is also concluded that there is a correlation between the speed of the UAV and the discrepancy between the established and actual camera tilt angles. PMID:27347954

    This report summarizes the main lessons learned from the research The climate challenge of food products in a holistic environmental and life cycle perspective, abbreviated KLIMAT. This was a research project in the period 2009-2012, conducted by Oestfoldforskning with the assistance of researchers from UMB, SIK (Sweden), MTT (Finland) and Aalborg University (Denmark). The project was funded by the Norwegian Research Council and its partners BAMA, Coop Norway, Norway Group, Nortura and Tine. The main objective of the project was to develop a uniform and scientifically based methodology to quantify the carbon footprint of food products to allow a fair comparison of food crops climate performance. This report summarizes a number of recommendations with regard to methodological choices in the implementation of greenhouse trace analysis of foodstuffs. The recommendations are divided into system boundaries, functional unit, allocation, and data quality and data variability. During the project period, a number of national and international initiatives have been launched to develop the calculation methodology. Therefore the objective of creating a standardized methodology was adjusted to prepare input to the methodology in the form of articles and reports.(Author)

    Full Text Available In 1699, translating from Greek a text by Maxim the Peloponnesian, Antim Ivireanul uses a word that, at first glance, coincides with a neologism attested in Romanian no sooner than the end of the 19th century, as a French loan: copt, –ă, ‘Locuitor [...] al Egiptului, descinzând din vechile secte creștine ale Euticheenilor’ [Inhabitant (... of Egypt, descending from the ancient Chris- tian sects of the Euticheens]. In order to answer the question in the title, the author had to conduct a semantic analysis of the corresponding word in the Greek source-text, i.e. κóπται (and also its etymology, since, for the period when Maxim the Peloponnesian writes, the Greek lexicography indicates only the existence of the ancient form κóπτης (pl. κóπται, derivative of the verb κóπ(τω –της ‘to cut, to strike’. The study leads towards an affirmative answer, and might also cast a new light on the language dynamics of the post-byzantine era.

    2004-07-01

    Grant Wood (1891-1942) was a major American regionalist artist from Iowa who produced his world famous icon, American Gothic in 1930. Along with Mona Lisa and Whistler's Mother, this work has become one of the most recognized paintings in the world. While it has been greatly admired by most of its viewers, it has been criticized by others. Currently on display at the Art Institute of Chicago, this oil painting portrays a grim faced farmer and his somber daughter who are resolutely standing in front of their rural, Gothic Revival farmhouse. The tall, gaunt farmer, looking straight ahead, firmly holds a pitchfork whose tines point upward, while his daughter, with her eyes averted appears to be showing disapproval. In American art, it is unusual to find the hard, cold realism and honest, direct and earthy qualities that Wood captures in American Gothic. Wood's actual intention was to present the work as a subtle and witty commentary on midwestern, rural life. To achieve his goal, Wood emulated the meticulous style and technique of the 16th century Flemish masters. His sister, Nan Wood Graham (1900-1990), and his 62-year-old dentist, Dr. Byron H. McKeeby (1867-1950), posed for the painting. This article describes how Grant developed this artistic style which is reflected in American Gothic. Additionally, it examines the strained interactions between Grant Wood, the artist, and Dr. Byron McKeeby, the model.

    2012-01-01

    Sacral neuromodulation (SNM) in urology is employed to treat refractory lower urinary tract dysfunction as well as chronic pelvic pain. Electrical stimulation of the sacral afferents (S2 - S4) causes activation and conditioning of higher autonomic and somatic neural structures and thereby influences the efferents controlling the urinary bladder, the rectum and their related sphincter systems. It is therefore possible to treat overactivity as well as hypocontractility and functional bladder neck obstruction. SNM treatment is conducted biphasically. Initially, test electrodes are placed to evaluate changes in micturition and pain parameters. If, in this first phase - called peripheral nerve evaluation (PNE test) - sufficient improvements are observed, the patient progresses to phase two which involves implantation of the permanent electrodes and impulse generator system. In recent years, the "two stage approach" with initial implantation of the permanent electrodes has been favoured as it increases treatment success rates. Long-term success rates of SNM vary significantly in the literature (50 - 80 %) due to heterogeneous patient populations as well as improved surgical approaches. With the introduction of "tined lead electrodes" (2002), tissue damage is reduced to a minimum. Technical innovation, financial feasibility (reimbursed in Germany since 2004) and wider application, especially in otherwise therapy-refractory patients or complex dysfunctions of the pelvis, have established SNM as a potent treatment option in urology. © Georg Thieme Verlag KG Stuttgart · New York.

    To assess risk factors and the extent of pulmonary hemorrhage complicating radiofrequency ablation (RFA) of pulmonary neoplasms. This retrospective study involved 248 ablation sessions for lung tumors (20 primary lesions and 228 metastatic lesions) in 164 patients (mean age 59.7 years, SD: 10.2). Both unipolar and bipolar radiofrequency systems were used under CT fluoroscopic guidance. Extent and underlying factors associated with development of pulmonary hemorrhage were analyzed. Incidence of intra-parenchymal pulmonary hemorrhage, pleural effusion, and hemoptysis were 17.7% (44/248 sessions), 4% (8/248 sessions), and 16.1% (40/248 sessions), respectively. Death because of massive bleeding occurred in one session (0.4%). Significant risk factors associated with intra-parenchymal hemorrhage included: lesions of <1.5 cm diameter (P = 0.007); basal and middle lung zone lesions (P = 0.026); increased needle track distance traversing the lung parenchyma >2.5 cm (P = 0.0017); traversing pulmonary vessels in the track of ablation (P < 0.001); and the use of multi-tined electrodes (P = 0.004). Concomitant incidence of pulmonary hemorrhage and pneumothorax was 29.2% (14/48 sessions). While typically safe, RFA of pulmonary neoplasms can result in pulmonary hemorrhage ranging from mild to life-threatening. Management of this complication is mainly preventive through adequate patient selection for ablation therapy and exclusion of technically avoidable risk factors. (orig.)

    Based on the Gas-Kinetic Unified Algorithm (GKUA) directly solving the Boltzmann model equation, the effect of rotational non-equilibrium is investigated recurring to the kinetic Rykov model with relaxation property of rotational degrees of freedom. The spin movement of diatomic molecule is described by moment of inertia, and the conservation of total angle momentum is taken as a new Boltzmann collision invariant. The molecular velocity distribution function is integrated by the weight factor on the internal energy, and the closed system of two kinetic controlling equations is obtained with inelastic and elastic collisions. The optimization selection technique of discrete velocity ordinate points and numerical quadrature rules for macroscopic flow variables with dynamic updating evolvement are developed to simulate hypersonic flows, and the gas-kinetic numerical scheme is constructed to capture the time evolution of the discretized velocity distribution functions. The gas-kinetic boundary conditions in thermodynamic non-equilibrium and numerical procedures are studied and implemented by directly acting on the velocity distribution function, and then the unified algorithm of Boltzmann model equation involving non-equilibrium effect is presented for the whole range of flow regimes. The hypersonic flows involving non-equilibrium effect are numerically simulated including the inner flows of shock wave structures in nitrogen with different Mach numbers of 1.5-Ma-25, the planar ramp flow with the whole range of Knudsen numbers of 0.0009-Kn-10 and the three-dimensional re-entering flows around tine double-cone body

    Investigations were carried out at two stations of Ornithological Unit, IBPN FEB RAS, located in Nizhnekolymsk District, Yakutia, starting from May 18-20 in 1984, 1985, 1987, 1988 and 1990. Duration of the pre-nesting period in 11 sandpiper species with different social organization was studied and compared with each other by allometric equations. As a characteristic of bird size the body mass was selected. Sandpipers come flying to the tundra at almost critical temperatures, to begin breeding as early as possible. Tining of breeding depends on birds feeding manner and the proximity to sites of overwintering. Duration of the pre-nesting period is invariable for every bird species and sex. There are sexual distinctions in time spent for the pre-nesting period in jointly-nesting sandpipers. The exponents in allometric equations that relate duration of the pre-nesting period with body mass are constant within a particular sex and differ between males and females. In different sexes, time spent for the pre-nesting period depends on mating, parental, and territorial systems. In sandpipers' males and females, this time is determined by the type of social organization. Relatively large sandpiper species seek to shortening of the pre-nesting period calendar time, which constrains their social organization. Monogamy and pair parental care lead to a necessity for spatial population structure to be controlled more strictly and maintained for a longer time. This, in turn, causes the increasing of males' time expenditures for such a behavior.

    To explore the attachments of the posterior zonule and vitreous in relation to accommodation and presbyopia in monkeys and humans. Novel scanning electron microscopy (SEM) and ultrasound biomicroscopy (UBM) techniques were used to visualize the anterior, intermediate, and posterior vitreous zonule and their connections to the ciliary body, vitreous membrane, lens capsule, and ora serrata, and to characterize their age-related changes and correlate them with loss of accommodative forward movement of the ciliary body. alpha-Chymotrypsin was used focally to lyse the vitreous zonule and determine the effect on movement of the accommodative apparatus in monkeys. The vitreous attached to the peripheral lens capsule and the ora serrata directly. The pars plana zonule and the posterior tines of the anterior zonule were separated from the vitreous membrane except for strategically placed attachments, collectively termed the vitreous zonule, that may modulate and smooth the forward and backward movements of the entire system. Age-dependent changes in these relationships correlated significantly with loss of accommodative amplitude. Lysis of the intermediate vitreous zonule partially restored accommodative movement. The vitreous zonule system may help to smoothly translate to the lens the driving forces of accommodation and disaccommodation generated by the ciliary muscle, while maintaining visual focus and protecting the lens capsule and ora serrata from acute tractional forces. Stiffening of the vitreous zonular system may contribute to age-related loss of accommodation and offer a therapeutic target for presbyopia.

    Fibre-optical temperature measuring methods are offering an approach to detect temperature profiles. According to the NAMUR-Technology-Roadmap the detection of temperature profiles is representing an increased benefit. Intrinsic fibre-optical temperature measuring techniques are presented, known as OTDRmethod (Optical tine domain reflectometry) facilitating a distributed temperature measurement method that allows a resolution in the range of decimetres. For the purpose of such applications a suitable photoncounting device comprises mechanical robust fibre-optical components, 3 db Coupler, referenced Laser- Diode, Y-Coupler with integrated band-filter and APD (Avalanche Diode) used in a detection module. A VHDL-coded FBGA-board provides a basic control-device for - a Laser-Driver to generate adjustable exiting-pulses in the range of nanoseconds at rates up to 100 kHz. - a Photon-Counting module with a minimum opening width in the range of one nanosecond - that permits the co-addition of the photon-counts derived from the spectral resolved Stokes and Anti-Stokes band.

    Alberto Urrets-Zavalía Jr was born in Córdoba (Argentina) in 1920. Chairman of the Department of Ophthalmology of the National University of Córdoba and founder of the Cornea and Glaucoma Surgical Center in the same city, in 1956 he created the first residency programme in Ophthalmology in his country. He founded the first Eye Bank and introduced one of the first argon laser photocoagulators in South America. He authored around 200 scientific presentations and publications, describing new findings and clinical entities. Thus, his individualisation of the cyclovertical component in strabismus contributed to important evolution of ideas concerning pathogenesis and therapy in oculomotor disorders of infancy. He was the first to propose the dehydration of the vitreous body in glaucoma patients before ocular surgery and developed a fixation pick and scleral depressor for retinal detachment surgery. He also described a new technique, the V-Z procedures for the correction of senile ectropion. In 1968, he published his Décollement de la rétine, considered a masterpiece in retinal detachment literature for many years. Urrets-Zavalía died in his native city at the age of 89. His prolific scientific and educational contributions make him one of the most brilliant and influential ophthalmologists of the 20th-century. © The Author(s) 2014.

    Full Text Available From many experiments with different kinds of tiIIage tools it is well known that an oscilating or vibrating movement of a tool can have a considerable influence on the draft required. Subsoiler represent tools of deep tillage, the function of subsoil plough to cutting deep tillage and to breaking hardpan soil. The hardpan soil can hinder drainage, aeration and pursue spreading of the soil nutrition. Therefore in split/cut the hardpan layer require by big enough of energy. This operation requires heavy-duty tractor because of high draft consumption, especially for breaking subsoil up to depth of 50 cm. Vibratory technique is one of the methods, which could be applied in order to reduce draft. On the other hand reduced draft can used by vibration, mechanism of vibration exploitedly with rotation of PTO changed become translation movement. However that vibration can greatly reduce the draft force needed, to pull a blade or tine trough soil, but this can only be achieved at the expense of an increase in the total powor consumed.

    The effects of different tillage systems on the properties and microbial diversity of an agricultural soil was investigated. In doing so, soil physical, chemical and biological properties were analysed in 2013-2015, on a long-term field experiment on a loamy sand at the IUNG-PIB Experimental Station in Grabów, Poland. Winter wheat was grown under two tillage treatments: conventional tillage using a mouldboard plough and traditional soil tillage equipment, and reduced tillage based on soil crushing-loosening equipment and a rigid-tine cultivator. Chopped wheat straw was used as a mulch on both treatments. Reduced tillage resulted in increased water content throughout the whole soil profile, in comparison with conventional tillage. Under reduced tillage, the content of readily dispersible clay was also reduced, and, therefore, soil stability was increased in the toplayers, compared with conventional tillage. In addition, the beneficial effects of reduced tillage were reflected in higher soil microbial activity as measured with dehydrogenases and hydrolysis of fluorescein diacetate, compared with conventional tillage. Moreover, the polimerase chain reaction - denaturing gradient gel electrophoresis analysis showed that soil under reduced till-age had greater diversity of microbial communities, compared with conventionally-tilled soil. Finally, reduced tillage increased organic matter content, stability in water and microbial diversity in the top layer of the soil.

    1568 ankylosing spondylitis patients, injected with repeated injections of /sup 224/Ra for treatment of their disease, have been observed in the GSF (study II). By the end of 1985 3 cases of malignant tumours in the skeleton had been observed, compared to 0 cases in a control group. According to the cancer mortality statistics for the FRG the age-corrected number of spontaneous bone tumours expected would be 0.4-0.7. In contrast, a recent risk estimate from the data of the patient group of study I (SPIESS/MAYS) who were treated with considerably higher doses, suggests an expected number of 5.8 radiation induced bone tumours for the present follow-up tine. Latest observations from that group show that bone tumours may occur up to 33 yr after treatment with /sup 224/Ra. Thus, the possibility of additional cases of bone tumours occurring in study II cannot be excluded. One striking observation was that 2 of the 3 skeletal tumours observed in study II were tumours of the bone marrow; there has been only 1 bone marrow tumour in the high dose group (study I) among 56 bone tumours. In addition there have been 6 and 5 leukaemias in the exposure and control group respectively. Of the 6 leukaemias in the exposure group 3 were chronic myeloid leukaemias (CML), whereas among the 5 leukaemias in the control group there was no CML.

  8. Calculation of cardiac pressures using left ventricular ejection fraction (LVEF) derived from radionuclide angiography

    Hommer, E.

    1981-01-01

    An attempt has been made to develop formulas to determine cardiac pressures in an undisturbed flow in patients without valvular or shunt diseases. These are based entirely on the results of left ventricular ejection fraction rates, permitting pressure analysis of several compartments at the same tine. According to BORER et al. they also enable determination of left ventricular 'Functional Reserve' after bycycle exercise as well as left ventricular 'Relaxation Reserve'. They support the views of NYHA in determining the grades of cardiac insufficiency proving the system- and low-pressure participation. A single formula for pulmonary flow can determine the pulmonary arterial pressure. The left ventricular enddiastolic pressure can also be exclusively calculated by values of left ventricular functions, thus both formulas may be used in disorders of the mitral valves. The possibility to calculate pressures of all the compartments of the heart from left ventricular ejection rate shows, that in undisturbed flow global heart function depends on left ventricular function. Therefore the mutual dependence of these formulas presents an intercompartimental pressure regulation of the heart through pulmonary flow and pulmonary vascular pressure, which leaves an aspect of autonomous cardiac regulation open to discussion.

    The purpose of this study was to determine serum reference values for crea- tine kinase (CK), aspartate aminotransferase (AST), and lactate dehydroge- nase (LDH) in captive-born and wild-caught owl monkeys to assess their usefulness for diagnosing myocardial disease. Urine samples were also collected and semi-quantitative tests performed. There was no statistically significant difference between CK, AST, and LDH when comparing both groups. However, when comparing monkeys with proteinuria to those without proteinuria, a statistically significant difference in CK value was observed (P = 0.021). In addition, the CK/AST ratio revealed that 29% of the animals included in this study had values suggesting cardiac infarction. Grossly, cardiac concentric hypertrophy of the left ventricle and small, pitted kidneys were the most common findings. Microscopically, myocardial fibrosis, contraction band necrosis, hypertrophy and hyperplasia of coronary arteries, medium-sized renal arteries, and afferent glomerular arteriolae were the most significant lesions, along with increased mesangial matrix and hypercellularity of glomeruli, Bowman’s capsule, and peritubular space fibroplasia. These findings suggest that CK, AST, and LDH along with urinalysis provide a reliable method for diagnosing cardiomyopathies in the owl monkey. In addition, CK/AST ratio, proteinuria, and the observed histological and ultrastructural changes suggest that Aotus vociferans suffer from arterial hypertension and chronic myocardial infarction.

Present paperhighlights a rare variation of branching patternof coeliac trunk which was observed during rou-tine dissection. In a 63 year old male cadaver,we observed a bifurcation of coeliac trunk intoshort hepato-splenic and longer hepato-gastrictrunks. The hepato-splenic trunk divided intocommon hepatic artery and splenic artery. Cys-tic artery originated from proper hepatic arteryand then proper hepatic artery divided into rightand left hepatic arteries. Hepato-gastric trunkran laterally and upward, and then it divided intotwo branches: a left gastric artery and left ac-cessory hepatic artery. Knowledge of this rarevariation is clinically very important for sur-geons, especially while performing liver trans-plantation, gastric, gallbladder surgeries andtransarterial chemoembolization for hepatictumor and during invasive procedures like an-giography and also other radiological studies.

    What is it like to live with the label "Disability?" NIB editorial staff and narrative symposium editors, Jeffery Bishop and Naomi Sunderland developed a call for stories, which was sent to several list serves, shared with the 1000 Voices Project community and posted on Narrative Inquiry in Bioethics' website. The request for personal stories from people who identify with the label "disabled" asked them to: consider how the label "disability" interacts with other aspects of their life in health care settings; does the term "disability" reflect their actual embodied experiences of impairment or does it fail to do justice to their particular experience of impairment; describe the kind of experiences that are possible because of the impairment(s); discuss how the label has affected their "authentic voice"; and many other concepts about what effects the label has on their lives. These authors share deeply personal experiences that will help readers understand their world, challenges, and joys. Thirteen stories are found in the print version of the journal and an additional five supplemental stories are published online only through Project MUSE. The stories are complemented by four commentary articles by Elizabeth R. Schiltz; Lorna Hallahan; Nicole Matthews, Kathleen Ellem, and Lesley Chenoweth; and Jeffery Bishop, Rachelle Barina, and Devan Stahl. These scholars come from the disciplines of law, social work, media studies, medicine, and bioethics from Australia and the United States. Together, the symposium's storytellers and commentators offer striking and informative insights into the everydayness of living with disabilities.

    Kathleen Kaska has done a remarkable job of capturing the life of Robert Porter Allen, truly one of the premier biologist/conservationists of the twentieth century. Allen, born in 1905, grew up reading outdoor adventure books and playing in the woods of northern Pennsylvania with his brother. At a young age, he was encouraged to join the Junior Audubon club and his passion for ornithology soon crystallized. He attended Lafayette College to study ornithology, but he was disinterested in academics and fared poorly. He dropped out after two years and joined the Merchant Marines. Not an auspicious beginning for such a highly respected scientist and conservationist! Soon, however, he landed a librarian job with Audubon and his diligence, acumen, and communication skills allowed him to take more and more responsibilities. He became one of the youngest Audubon sanctuary directors ever appointed, and he was also able to secure a fellowship through Cornell to work on Roseate Spoonbills (Platalea ajaja). Audubon later appointed him to lead their Whooping Crane (Grus americana) studies.

Pressure ulcers have significant impact on emotional and physical wellbeing, quality of life, and health care costs. The use of wound dressings could be an important and cost-effective strategy in preventing pressure ulcers. The main types of dressings that are examined for this purpose in the literature are foam, hydrocolloid, and films. Some small studies have shown a preventative role for sacral dressings with low-shear backings, though they raise concerns about over-hydration of the skin. Further research demonstrates the application of barrier films over bony prominences to have a prophylactic effect; however, adhesive dressings can also contribute to shearing forces on the skin. There is a vast body of research that examines the use of dressings to prevent pressure ulcers; however, there is limited high-level evidence, such as randomized control trials. A 2013 Cochrane review indicated that there is a paucity of high-level evidence to support the prophylactic use of dressings to prevent pressure ulcers; this paper will examine the emerging literature and consider its relevance to pressure ulcer prevention protocols.

    Recent content analyses of YouTube postings reveal a proliferation of user generated videos with misleading statements about the health consequences of various types of nontraditional tobacco use (eg, electronic cigarettes; e-cigarettes). This research was aimed at obtaining evidence about the potential effects of YouTube postings about tobacco products on viewers' attitudes toward these products. A sample of young adults recruited online (N=350) viewed one of four highly viewed YouTube videos containing misleading health statements about chewing tobacco, e-cigarettes, hookahs, and pipe smoking, as well as a control YouTube video unrelated to tobacco products. The videos about e-cigarettes and hookahs led to more positive attitudes toward the featured products than did control videos. However, these effects did not fully translate into attitudes toward combustive cigarette smoking, although the pipe video led to more positive attitudes toward combustive smoking than did the chewing and the hookah videos, and the e-cigarette video led to more positive attitudes toward combustive cigarette smoking than did the chewing video. This research revealed young people's reactions to misleading claims about tobacco products featured in popular YouTube videos. Policy implications are discussed. ©Dolores Albarracin, Daniel Romer, Christopher Jones, Kathleen Hall Jamieson, Patrick Jamieson.

    Full Text Available Kathleen Abrahamson1, Morgan Durham1, Rebekah Fox21Department of Public Health, Western Kentucky University, Bowling Green, KY, USA; 2Department of Communication, Texas State University, San Marcos, TX, USAAbstract: In this article, we synthesize current literature regarding the unmet needs of cancer patients, with a specific focus on interventions that address psychosocial distress, social support, and information deficits. Research indicates many patients diagnosed with cancer express unmet needs in terms of emotional distress, decision-making support, and practical concerns such as childcare, transportation, and financial assistance. Four types of system-level barriers to the meeting of patient psychosocial and information-based needs emerge from the literature: underidentification of needs due to inadequate assessment, time constraints on cancer care providers, lack of adequate reimbursement for psychosocial and information services, and barriers related to communication of disease-related information. There is also evidence that unmet need, especially unmet information need, is related to the level of patient health literacy. Patient empowerment through the resolution of unmet needs increases patient participation in care, and is especially crucial in regards to understanding risks and benefits of treatment. There is evidence that some interventions are effective for some patients, and that even relatively simple interventions can reduce psychosocial and information-based needs. The challenge is therefore to discover which intervention will be effective for each individual patient, and to attain the skills and resources necessary to intervene appropriately.Keywords: cancer, unmet need, health literacy, intervention

    A 2009 report by the National Research Council (NRC) reviewed a previous study on Mars Sample Return (1997) and provided updated recommendations for future sample return mis-sions based on our current understanding about Mars and its biological potential, as well as advances in technology and analytical capabilities. The committee* made 12 specific recommen-dations that fall into three general categories—one related to current scientific understanding, ten based on changes in the technical and/or policy environment, and one aimed at public com-munication. Substantive changes from the 1997 report relate mainly to protocols and methods, technology and infrastructure, and general oversight. This presentation provides an overview of the 2009 report and its recommendations and analyzes how they may impact mission designs and plans.

    2013-08-01

    Full Text Available Moffatt’s Up in the Sky series draws attention to the relation between sky and earth, through the content and camera angles of the images. Similarly, Kathleen Petyarre’s Central Desert acrylic dot painting evokes this relation representing country and Dreaming from a celestial perspective—as she says ‘looking from the sky’. Yet here any association between these artists seems to end with the urban artist refusing to engage Aboriginal tradition and the desert artist focused on Dreaming, country and heritage. However, a further connection between these disparate works may also be discerned as each, in differing ways, transforms our conventional perceptions of space and time. Reading these images in relation to Walter Benjamin’s concepts of the auratic and of messianic time, I suggest that each restructures dimension and duration putting in question the (postmodern calibrations of our space/time experience. This paper stages an engagement between these artists’ works and Benjamin’s concepts exploring the variations and modifications of the spatial and the temporal that hybrid cross-cultural exchanges require and facilitate.

Data were collected from 212 heart transplant patients (80% male, 92% white, mean age 59.9 years at four United States sites using the Heart Transplant Stressor Scale, Social Support Index, Jalowiec Coping Scale, and Quality of Life Index. Using Baron and Kenny's approach, a series of regression equations for mediation revealed that both satisfaction with social support and coping partially mediated the relationship between perceived stress and HRQOL. Understanding the relationships of social support, stress, and coping on patients' HRQOL is important for the development of interventions to provide optimal patient care.

    In early 2009, a state policing agency raided a clandestine drug laboratory in a suburb of a major city in Australia. While searching the laboratory, they discovered a small glass jar labelled 'Gamma Source' and containing a green powder. The powder was radioactive. This paper documents the detailed nuclear forensic analysis undertaken to characterize and identify the material and determine its provenance. Isotopic and impurity content, phase composition, microstructure and other characteristics were measured on the seized sample, and the results were compared with similar material obtained from the suspected source (ore and ore concentrate material). While an extensive range of parameters were measured, the key 'nuclear forensic signatures' used to identify the material were the U isotopic composition, Pb and Sr isotope ratios, and the rare earth element pattern. These measurements, in combination with statistical analysis of the elemental and isotopic content of the material against a database of uranium ore concentrates sourced from mines located worldwide, led to the conclusion that the seized material (a uranium ore concentrate of natural isotopic abundance) most likely originated from Mary Kathleen, a former Australian uranium mine

However, several cardiovascular complications including hypertension, cardiomyopathy, stroke, pulmonary embolism, fatal and nonfatal arrhythmias, and myocardial infarction have been reported with supraphysiologic doses of anabolic steroids. We report a case of an acute ST-segment elevation myocardial infarction in a patient with traditional cardiac risk factors using supraphysiologic doses of supplemental, intramuscular testosterone. In addition, this patient also had polycythemia, likely secondary to high-dose testosterone. The patient underwent successful percutaneous intervention of the right coronary artery. Phlebotomy was used to treat the polycythemia acutely. We suggest that the chronic and recent “stacked” use of intramuscular testosterone as well as the resultant polycythemia and likely increased plasma viscosity may have been contributing factors to this cardiovascular event, in addition to traditional coronary risk factors. Physicians and patients should be aware of the clinical consequences of anabolic steroid abuse.Keywords: acute myocardial infarction, anabolic steroid use, polycythemia

    Full Text Available While the accountability and standardization movement continues to narrow curriculum in the US, unschooling families are redefining learning and recreating community in an atmosphere of love and trust. As professors of education and unschooling mothers, Rolstad and Kesson compare their unschooling experiences in two different eras, one in the early days of unschooling (1980s, and the other in the first decade of the 21st century. Kathleen Kesson was an unschooling pioneer when her children were unschooled in the early 1980s, and her children are now adults. She describes what it was like to unschool then, to do what she terms old school unschooling. Only a generation later, Kellie Rolstad began unschooling her three children, in a world transformed by the Internet and ease of access to both information and social networking, key components of unschooling today. Rolstad describes how her unschooling children connected play in real and virtual worlds, exploring ideas differently in many aspects from how Kessons children played and explored, and yet fundamentally and remarkably the same. In this article, Rolstad and Kesson share their experiences of trusting children, of giving them the space and the resources to learn and grow in the ways that are best for them, comparing along the way what it was like to unschool then and what it is like to unschool now, in this era when our society has come to distrust children more than ever.

  6. Proceedings of the switched power workshop

    These proceedings contain most of the presentations given at a workshop on the current state of research in techniques for switched power acceleration. The proceedings are divided, as was the workshop itself, into two parts. Part 1, contains the latest results from a number of groups active in switched power research. The major topic here is a method for switching externally supplied power onto a transmission line. Advocates for vacuum photodiode switching, solid state switching, gas switching, and synthetic pulse generation are all presented. Other important areas of research described in this section concern: external electrical and laser pulsing systems; the properties of the created electromagnetic pulse; structures used for transporting the electromagnetic pulse to the region where the electron beam is located; and possible applications. Part 2 of the proceedings considers the problem of designing a high brightness electron gun using switched power as the power source. This is an important first step in demonstrating the usefulness of switched power techniques for accelerator physics. In addition such a gun could have immediate practical importance for advanced acceleration studies since the brightness could exceed that of present sources by several orders of magnitude. I would like to take this opportunity to thank Kathleen Tuohy and Patricia Tuttle for their assistance in organizing and running the workshop. Their tireless efforts contribute greatly to a very productive meeting

    Full Text Available Fredy Chaparro-Rojas, Kathleen M MullaneDepartment of Medicine, Section of Infectious Diseases, University of Chicago, Chicago, IL, USAAbstract: The epidemiology of Clostridium difficile infections (CDI has evolved during the last decades, with an increase in the reported incidence, severity of cases, and rate of mortality and relapses. These increases have primarily affected some special populations including the elderly, patients requiring concomitant antibiotic therapy, patients with renal failure, and patients with cancer. Until recently, the treatment of CDI was limited to either metronidazole or vancomycin. New therapeutic options have emerged to address the shortcomings of current antibiotic therapy. Fidaxomicin stands out as the first-in-class oral macrocyclic antibiotic with targeted activity against C. difficile and minimal collateral damage on the normal colonic flora. Fidaxomicin has demonstrated performance not inferior to what is considered the “gold standard” available therapy for CDI, vancomycin, in two separate Phase III clinical trials, but with significant advantages, including fewer recurrences and higher rates of sustained clinical cures. Fidaxomicin constitutes an important development in targeted antibiotic therapy for CDI and must be considered as a first-line agent for patients with risk factors known to portend relapse and severe infection.Keywords: fidaxomicin, Clostridium difficile-associated diarrhea, CDAD, Clostridium difficile infection (CDI, vancomycin, metronidazole

    A field trial was done in the Upper Tiffin River Watershed, in southeastern Michigan, to determine the influence of liquid dairy manure effluent (LDME) management practices on the quality of agricultural subsurface-drain water. Samples from subsurface drains were analyzed for nutrients, fecal-coliform and Escherichia coli (E. coli) bacteria, antibiotics, chemicals typically detected in wastewater, and the occurrence of genes indicating the presence of shiga-toxin-producing E. coli, or of bovine-specific Bacteroidetes bacteria. Samples were collected from November 2, 2006, to March 20, 2007, from eight subsurface drains under field plots that received no LDME and no tillage (controls) or received 4,000 or 8,000 gallons per acre (gal/acre) of LDME and either no tillage or two different types of tillage. The two types of tillage tested were (1) ground-driven, rotary, subsurface cultivation and (2) rolling-tine aeration. Samples were collected before LDME application and at 4 hours, and 1, 2, 6, 7, and 14 days post-application. Nutrient concentrations were high in subsurface-drain water throughout the field-trial period and could not be attributed to the field-trial LDME application. Of the 59 drain-water samples, including those collected before LDME application and control samples for each date, 56 had concentrations greater than the U.S. Environmental Protection Agency (USEPA), Ecoregion VI recommended surface-water criterion for total phosphorus, and all samples had concentrations greater than the recommended total nitrogen criterion. Nitrate + nitrite nitrogen concentration exceeded 20 milligrams per liter for every sample and contributed most to the total nitrogen concentrations. Substantial increases in drain-water concentrations of organic and ammonia nitrogen and total phosphorus were found for all treatments, including controls, at 14 days post-application after 0.84 inch of rainfall over 2 days. E. coli concentrations exceeded the USEPA recreational

    PurposeThe purpose of this study was to evaluate need for antibiotic prophylaxis for radiofrequency ablation (RFA) of liver tumors in patients with no significant co-existing risk factors for infection.Materials and MethodsFrom January 2004 to September 2013, 83 patients underwent 123 percutaneous RFA procedures for total of 152 hepatocellular carcinoma (HCC) lesions. None of the patients had pre-existing biliary enteric anastomosis (BEA) or any biliary tract abnormality predisposing to ascending biliary infection or uncontrolled diabetes mellitus. No pre- or post-procedure antibiotic prophylaxis was provided for 121 procedures. Data for potential risk factors were reviewed retrospectively and analyzed for the frequency of infectious complications, including abscess formation.ResultsOne patient (1/121 (0.8 %) RFA sessions) developed a large segment 5 liver abscess/infected biloma communicating with the gallbladder 7 weeks after the procedure, successfully treated over 10 weeks with IV and PO antibiotic therapy and percutaneous catheter drainage. This patient did not receive any antibiotics prior to RFA. During the procedure, there was inadvertent placement of RFA probe tines into the gallbladder. No other infectious complications were documented.ConclusionThese data suggest that the routine use of prophylactic antibiotics for liver RFA is not necessary in majority of the patients undergoing liver ablation for HCC and could be limited to patients with high-risk factors such as the presence of BEA or other biliary abnormalities, uncontrolled diabetes mellitus, and large centrally located tumors in close proximity to central bile ducts. Larger randomized studies are needed to confirm this hypothesis

    Herbicide runoff from cropping fields has been identified as a threat to the Great Barrier Reef ecosystem. A field investigation was carried out to monitor the changes in runoff water quality resulting from four different sugarcane cropping systems that included different herbicides and contrasting tillage and trash management practices. These include (i) Conventional - Tillage (beds and inter-rows) with residual herbicides used; (ii) Improved - only the beds were tilled (zonal) with reduced residual herbicides used; (iii) Aspirational - minimum tillage (one pass of a single tine ripper before planting) with trash mulch, no residual herbicides and a legume intercrop after cane establishment; and (iv) New Farming System (NFS) - minimum tillage as in Aspirational practice with a grain legume rotation and a combination of residual and knockdown herbicides. Results suggest soil and trash management had a larger effect on the herbicide losses in runoff than the physico-chemical properties of herbicides. Improved practices with 30% lower atrazine application rates than used in conventional systems produced reduced runoff volumes by 40% and atrazine loss by 62%. There were a 2-fold variation in atrazine and >10-fold variation in metribuzin loads in runoff water between reduced tillage systems differing in soil disturbance and surface residue cover from the previous rotation crops, despite the same herbicide application rates. The elevated risk of offsite losses from herbicides was illustrated by the high concentrations of diuron (14μgL(-1)) recorded in runoff that occurred >2.5months after herbicide application in a 1(st) ratoon crop. A cropping system employing less persistent non-selective herbicides and an inter-row soybean mulch resulted in no residual herbicide contamination in runoff water, but recorded 12.3% lower yield compared to Conventional practice. These findings reveal a trade-off between achieving good water quality with minimal herbicide contamination and

Methods: The study population consisted of 20 adults with type 1 diabetes. The sample was diverse in relation to educational background, age, sex, and cohabitation status. Inspired by action research, several methods and perspectives on peer support were explored and tested. Workshops and group and individual interviews were performed. Systematic text condensation was used to analyze data, supplemented with theory-based interpretive analysis. Results: Adults with type 1 diabetes found peer support highly relevant to reduce a burdensome feeling of diabetes-specific loneliness. Peer support showed potential to create diabetes-specific social capital not only by creating reciprocal social support between peers but also, more importantly, by creating space for genuine trust and a feeling of communality. There was a widespread feeling of the pervasive impact of diabetes on daily life and thus the relevance of discussing all aspects of life. However, participants perceived peer support as particularly relevant in relation to big changes in life, for example, in family life, at work, or through treatment events such as getting an insulin pump. Conclusion: Peer support programs focusing on creating and establishing diabetes-specific social capital using participatory approaches seem highly relevant among adults with type 1 diabetes. Content, methods, and effects of peer support need further exploration in collaboration with adults with type 1 diabetes.

    Objective: To explore virtual three-dimensional (3D) model for intravascular interventional devices,the method of preoperative simulation and its value in clinical work. Methods: The virtual models including catheter, guide wire, stent and coil were established by using the 3D moulding software of 3D Studio MAX R3. The interventional preoperative simulation was performed on personal computer including 21 patients of cerebral aneurysm embolization (anterior communicating artery 5, posterior communicating artery 10,middle cerebral artery 3, internal carotid artery 2, and vertebral artery 1), during interventional procedures, the surgeon relied on the simulation results for plastic micro-guide wire, catheter and the release of micro-coils and stents. Results: (1) All the virtual instruments and real instruments had similar shape,the overall tine for constructing virtual model was about 20 hours. The preoperative simulation took 50 to 80 minutes. (2) The simulation result of catheter insertion in the 18 cases had relevant value to guide micro-catheter, molding micro-guide wire tip, and shortened the operating time. For embolization, the simulation results of filling coil and releasing stent were similar to surgical results in 76% of the patients (16/21). (3)For teaching and training, 93% (38/41) of doctors in training believed that preoperative simulation facilitated the understanding of surgery. Conclusions: The method of virtual model of intravascular interventional devices was reliable. The preoperative simulation results could be used to guide practical clinical operation with relatively high degree of similarity, and could play a role in promoting researches on interventional virtual operations.

  15. What enables size-selective trophy hunting of wildlife?

    Directory of Open Access Journals (Sweden)

    Chris T Darimont

    Full Text Available Although rarely considered predators, wildlife hunters can function as important ecological and evolutionary agents. In part, their influence relates to targeting of large reproductive adults within prey populations. Despite known impacts of size-selective harvests, however, we know little about what enables hunters to kill these older, rarer, and presumably more wary individuals. In other mammalian predators, predatory performance varies with knowledge and physical condition, which accumulates and declines, respectively, with age. Moreover, some species evolved camouflage as a physical trait to aid in predatory performance. In this work, we tested whether knowledge-based faculty (use of a hunting guide with accumulated experience in specific areas, physical traits (relative body mass [RBM] and camouflage clothing, and age can predict predatory performance. We measured performance as do many hunters: size of killed cervid prey, using the number of antler tines as a proxy. Examining ∼ 4300 online photographs of hunters posing with carcasses, we found that only the presence of guides increased the odds of killing larger prey. Accounting for this effect, modest evidence suggested that unguided hunters presumably handicapped with the highest RBM actually had greater odds of killing large prey. There was no association with hunter age, perhaps because of our coarse measure (presence of grey hair and the performance trade-offs between knowledge accumulation and physical deterioration with age. Despite its prevalence among sampled hunters (80%, camouflage had no influence on size of killed prey. Should these patterns be representative of other areas and prey, and our interpretations correct, evolutionarily-enlightened harvest management might benefit from regulatory scrutiny on guided hunting. More broadly, we suggest that by being nutritionally and demographically de-coupled from prey and aided by efficient killing technology and road access

    N. E. Rudenko

    2017-01-01

    Full Text Available Inter-row cultivators have some shortcomings: design is complicated due to placing on each section of a 4-unit (parallelogram suspension of working tools; as the copying means use wheels which are mounted at distance from working tools, in other vertical plane, and have negative effect on variability of tillage depth; working tools are V-shaped hoes with a crumbling angle not more than 16 degrees. In the operation course the parts of a leg and a hoe, moving in the soil, raise it and throw to the side, creating not aligned surface grooves are formed, imposed moist soil. These processes are exacerbated by increasing the operating speed of the cultivator. The authors offered a resource-saving inter-row cultivator with a radial suspension of working tools. A flat plate spring was used as a beam. This simplifies the design, eliminates the horizontal oscillations of the working tools, provides a constant pressing them in the process. The working tool in the form of a flat lancet plowshares with a spiral fixed on the leg was designed. Operating width of a ploughshare is of 420 mm, thickness equals 4 (5 mm. The spiral with a diameter of 50 mm is made of a carbon spring wire with a diameter of 2-3 mm. One hoe is set instead of three-five tines on each section, that significantly reduces material consumption. A plough share with a spiral form the swinging-loosening element that provides creating a fine lumpy topsoil. The ploughshare performs the copying functions therefore the additional copying wheels are not required. Tests showed that the new working tool of a cultivator allows to operate qualitatively at a speed up to 14-18 km/h.

Con estas estrategias de acción colectiva, que suponían una “salida” al espacio público, se trataba de hacer visible allí la fuerza del movimiento y reafirmar la presencia física de este, sus reivindicaciones y aspiraciones. Esta visibilidad se reforzaba mediante el despliegue de los símbolos propios: himnos, canciones, banderas, etc.

    To increase an efficiency of complex treatment of patients with diaphyseal gunshot fractures of long bones by introduction of modern minimally invasive surgical techniques of internal osteosynthesis into clinical practice of civil health care and to improve the outcomes in victims. Prospective comparative clinical trial included 104 victims from the Republic of Yemen with gunshot wounds of limbs of various severity for the period 2009-2011. There were diaphyseal fractures of long bones of limbs associated with soft tissue injuries. Men were predominant (80.7%). Age ranged from 15 to 80 years (mean 38,5 ± 5,7 years). Various surgical techniques of simultaneous and staged treatment were used for gunshot fractures of long bones of limbs. Additional immune therapy was prescribed to prevent infectious complications in the most severe cases. Victims were comprehensively treated according to different staged treatment: conventional surgical treatment with external fixation devices or early primary minimally invasive functionally stable osteosynthesis with LCP/BIOS plates were applied for low-energy fractures; in case of high-energy fractures the first stage included external fixation devices deployment followed by their subsequent replacement during delayed minimally invasive osteosynthesis. The essence of improvement is pursuit to simultaneous minimally invasive surgery by using of current plates for osteosynthesis and preventive immunotherapy of immune dysfunction to eliminate infectious complications. As a result, we obtained 2-fold decrease of surgical invasiveness (r≤0,01) and hospital-stay (r≤0,01). Repeated osteosynthesis was not made. Also 4-fold and 40-fold reduction of infectious and noninfectious complications was observed. This management was accompanied by reduced rehabilitation tine and significantly improved quality of life. Improved technique and algorithm of complex treatment of diaphyseal gunshot fractures of long bones of limbs were described

    Electrokinetic remediation of chromium contaminated soil has been demonstrated for unsaturated 50-100 mesh sand with 10% moisture by weight. The initial region of sand contaminated with 100 ppm w chromate ions was completely cleansed of contamination. After 22 hours of treatment, chromate was found near the anode and apparently migrated at a rate of at least 0.40 cm/hr with a pore water current density of 2.26mA/cm 2 . An analogous run was made using the same sand and FD and C Red No. 40 as the contaminant at a molar concentration equivalent to the 100 ppm w Cr run. The position of the migrating dye was monitored photographically. After similar treatment conditions, the visual dye concentration profile exhibited characteristics similar to the chromate. The migration rate of the dye was slower than the chromate but the qualitative similarity of behavior in an electric field suggests the dye is an analog for chromate ions. The slower migration rate of the dye is not unexpected because the dye molecule is larger than chromate. The use of dye as an analog for chromate greatly accelerates the experimentation process in unsaturated soil because destructive sampling is not required to monitor the contaminant location. Experiments were also conducted to determine the effect of soil heterogeneities on the electrokinetic processes. Unsaturated sands in size fractions of 50-100 mesh (medium) and 100-200 mesh (fine) were studied both individually and in layers. The dye migration rate was accelerated in the tine sand and slowed in the medium sand of the layered experiment when compared with the corresponding individual experiments. This discrepancy was explained by estimating the current density in each layer which was proportionally higher in the fine layer and lower in the medium layer. These preliminary experiments illustrate the significant dependence of electromigration rates on current density. (author)

    An autopilot scheme of volumetric-modulated arc therapy (VMAT)/intensity-modulated radiation therapy (IMRT) planning with the guidance of prior knowl-edge is established with recorded interactions between a planner and a commercial treatment planning system (TPS). Microsoft (MS) Visual Studio Coded UI is applied to record some common planner-TPS interactions as subroutines. The TPS used in this study is a Windows-based Eclipse system. The interactions of our application program with Eclipse TPS are realized through a series of subrou-tines obtained by prerecording the mouse clicks or keyboard strokes of a planner in operating the TPS. A strategy to autopilot Eclipse VMAT/IMRT plan selection process is developed as a specific example of the proposed "scripting" method. The autopiloted planning is navigated by a decision function constructed with a reference plan that has the same prescription and similar anatomy with the case at hand. The calculation proceeds by alternating between the Eclipse optimization and the outer-loop optimization independent of the Eclipse. In the C# program, the dosimetric characteristics of a reference treatment plan are used to assess and modify the Eclipse planning parameters and to guide the search for a clinically sensible treatment plan. The approach is applied to plan a head and neck (HN) VMAT case and a prostate IMRT case. Our study demonstrated the feasibility of application programming method in C# environment with recorded interactions of planner-TPS. The process mimics a planner's planning process and automatically provides clinically sensible treatment plans that would otherwise require a large amount of manual trial and error of a planner. The proposed technique enables us to harness a commercial TPS by application programming via the use of recorded human computer interactions and provides an effective tool to greatly facilitate the treatment planning process. © 2016 The Authors.

    We report on high-resolution infrared spectroscopy of ethane (C2H6) performed at the latitude of an impact site on Jupiter discovered on 19 July 2009 by A. Wesley from a location in Murrumbateman, Australia. The observations used the NASA Goddard Space Flight Center's Heterodyne Instrument for Planetary Wind and Composition (HIPWAC) at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii. HIPWAC is a mid-infrared (9-12 microns) heterodyne spectrometer operating at the highest limit of spectral resolving power (lambda\\Delta\\lambda > l06), providing information on atmospheric constituent abundance and temperature through fully resolved tine shapes. Ethane is a stable trace product of methane photochemistry that is nearly uniformly mixed in Jupiter's stratosphere, providing an effective probe of that altitude region. Ethane emission line profiles near 11,74 microns in the Ug band were measured in Jupiter's stratosphere at 25 MHz (11.00083/cm) resolution. A sequence of spectra of ethane acquired over a range of longitude at the impact latitude (56S planetocentric) probes constituent abundance and temperature profile, both on and off the impact region. Near the site of the impact, ethane emission increased above levels measured well outside the impact region. Radiative transfer analysis indicates increased ethane mole fraction (30% greater). Variation in the measured continuum level and line intensities within 75deg of the impact longitude indicate the presence of an opacity source (haze) at altitudes near and above the tropopause and as high as the 10-mbar level near the impact site. The indication of possible haze opacity up to the 10-mbar level in the atmosphere is consistent with measurements made by HIPWAC's predecessor as part of the IRTF Shoemaker Levy-9 campaign in 1994.

    Full Text Available Abstract The biometry, demography and genetics of red deer Cervus elaphus of Mesola Wood (NE Italy, are presented and discussed in relation to the conservation of this population. Modest body size, low stature, oversimplified antlers and a low reproductive performance characterise red deer from Mesola Wood. The mitochondrial genome showed a private haplotype, different from other red deer in Italy and central Europe. The uniqueness of this nucleus and its biogeographic importance make a long-term conservation plan particularly urgent. Management measures such as fallow deer reduction, winter feeding and pasture mowing were tested, giving promising results. The physical condition of the animals improved, calf and adult mortality declined, and a few cases of antlers with bez tine or crown were reported in this study after four decades.

    Full Text Available Background: Cementless hip prosthesis was designed to provide biologic fixation, without the use of cement. The second generation components have shown more reliable bone ingrowths and survival rates. We are reporting a midterm result of two designs of cementless prosthesis in a unique culture with different social habits and expectations. Methods: 52 primary cementless total hip arthroplasty in 42 patients with the mean age of 48.8 years were retrospectively studied. Two groups of prosthesis had been implanted: Harris-Galante II (HGII in 15 and Versys-Trilogy (V-T in 37 hips, both from Zimmer company. The patients were assessed clinically, radiographically and with Harris hip score, SF36, WOMAC, and MACTAR questionnaires, with 65 months (26-136 mean follow-up. Results: All the V-T prostheses had survived well. Eight of HG II were revised by the last follow-up in 19-102 months. All had undergone acetabular revision and 2 combined with femoral revision. Broken tines of HGII cups were seen in 4 radiographs. The 65 months overall survival was 96.2% for femoral and 84.6% for acetabular components. 90% had good or excellent Harris hip scores. The functional scores were poorer in the HG II group. Pain relief and improved walking were the two main patients’ expectations fulfilled in 97.6% and 92.8%, respectively. Conclusions: The outcome of cementless total hip arthroplasty (THA is satisfactory and comparable with the literature based on the results of function and survival of this small comparative group. The use of HGII acetabular component should be abandoned.

  9. The Calibration and Use of Capacitance Sensors to Monitor Stem Water Content in Trees.

    Water transport and storage through the soil-plant-atmosphere continuum is critical to the terrestrial water cycle, and has become a major research focus area. Biomass capacitance plays an integral role in the avoidance of hydraulic impairment to transpiration. However, high temporal resolution measurements of dynamic changes in the hydraulic capacitance of large trees are rare. Here, we present procedures for the calibration and use of capacitance sensors, typically used to monitor soil water content, to measure the volumetric water content in trees in the field. Frequency domain reflectometry-style observations are sensitive to the density of the media being studied. Therefore, it is necessary to perform species-specific calibrations to convert from the sensor-reported values of dielectric permittivity to volumetric water content. Calibration is performed on a harvested branch or stem cut into segments that are dried or re-hydrated to produce a full range of water contents used to generate a best-fit regression with sensor observations. Sensors are inserted into calibration segments or installed in trees after pre-drilling holes to a tolerance fit using a fabricated template to ensure proper drill alignment. Special care is taken to ensure that sensor tines make good contact with the surrounding media, while allowing them to be inserted without excessive force. Volumetric water content dynamics observed via the presented methodology align with sap flow measurements recorded using thermal dissipation techniques and environmental forcing data. Biomass water content data can be used to observe the onset of water stress, drought response and recovery, and has the potential to be applied to the calibration and evaluation of new plant-level hydrodynamics models, as well as to the partitioning of remotely sensed moisture products into above- and belowground components.

  10. Nutrient Runoff Losses from Liquid Dairy Manure Applied with Low-Disturbance Methods.

    Manure applied to cropland is a source of phosphorus (P) and nitrogen (N) in surface runoff and can contribute to impairment of surface waters. Tillage immediately after application incorporates manure into the soil, which may reduce nutrient loss in runoff as well as N loss via NH volatilization. However, tillage also incorporates crop residue, which reduces surface cover and may increase erosion potential. We applied liquid dairy manure in a silage corn ( L.)-cereal rye ( L.) cover crop system in late October using methods designed to incorporate manure with minimal soil and residue disturbance. These include strip-till injection and tine aerator-band manure application, which were compared with standard broadcast application, either incorporated with a disk or left on the surface. Runoff was generated with a portable rainfall simulator (42 mm h for 30 min) three separate times: (i) 2 to 5 d after the October manure application, (ii) in early spring, and (iii) after tillage and planting. In the postmanure application runoff, the highest losses of total P and dissolved reactive P were from surface-applied manure. Dissolved P loss was reduced 98% by strip-till injection; this result was not statistically different from the no-manure control. Reductions from the aerator band method and disk incorporation were 53 and 80%, respectively. Total P losses followed a similar pattern, with 87% reduction from injected manure. Runoff losses of N had generally similar patterns to those of P. Losses of P and N were, in most cases, lower in the spring rain simulations with fewer significant treatment effects. Overall, results show that low-disturbance manure application methods can significantly reduce nutrient runoff losses compared with surface application while maintaining residue cover better than incorporation by tillage.

    Integrated pest management has been implemented as a general practice by EU legislation. As weed control actually is the most important crop protection measure in maize for Western Europe, the new legislation will have its impact. The question is of course which systems can be successfully implemented in practice with respect to labour efficiency and economical parameters. During 3 successive growing seasons (2007, 2008, 2009) weed control in maize was evaluated, the main focus was put on different techniques of integrated weed control and was compared with chemical weed control. Additionally, during 4 successive growing seasons (2011, 2012, 2013 and 2014) two objects based on integrated weed control and two objects based on mechanical weed control were compared to about twenty different objects of conventional chemical weed control. One of the objects based on mechanical weed control consisted of treatment with the flex-tine harrow before and after emergence in combination with chemical weed control at a reduced rate in 3-4 leave stage. The second one consisted of broadcast mechanical treatments before and after emergence followed by a final in-row application of herbicides and an inter-row cultivation at 6-7(8) leave stage. All trials were conducted on the Experimental farm of Bottelare HoGent-UGent on a sandy loam soil. Maize was growing in 1/3 crop rotation. The effect on weed growth as well as the economic impact of the different applications was evaluated. Combining chemical and mechanical weed control is a possible option in conventional farming but the disadvantages must be taken into account. A better planned weed control based on the real present weed-population in combination with a carefully thought-out choice of herbicides should also be considered as an IPM--approach.

  12. Comparative study of Nd(3+) emission from 4f2 5d and 4f3 configurations induced by multiphotonic process in YLF, GLF and LLF crystals

    Nd 3+ ultraviolet fluorescence induced by multiphotonic laser excitations was studied in Nd-doped YLiF 4 (YLF) and LuLiF 4 (LLF) crystals by using the time resolved spectroscopy technique. The UV luminescences are due to transitions between the 4f 2 5d and the 4f 3 electronic configurations of Nd 3+ ions. The 4f 2 5d configuration can be reached by direct pumping the UV transition or by multiphotonic excitation, both processes give raise to the UV emission band with a structure due to the strong phonon coupling, expected for a 5d orbital involvement in the transition. The multiphotonic excitation process is due to three photons (532 nm) sequential absorptions of 532 nm-photons by metastable levels of the 4f 3 configuration splitted by crystalline local field. The sequential excitation of Nd by the pumping laser is attributed to the 4 I 9/2 +532nm → 4 G 7/2 ground state absorption followed by the 4 G 7/2 +532 nm →2 F 5/2 and 2 F 5/2 +532 nm → 4f 2 5d excited state absorptions. The UV emissions due to 4f 2 5d configuration are parity allowed, having lifetime of 35 ns in contrast to UV emissions from 4f 3 configuration which are induced by two absorption steps and are parity forbidden showing longer lifetime of 8μs and narrow tines. The polarization effects of the UV emissions were studied and their behavior are dependent on the excited state configuration involving or not the 5d orbital. The allowed UV emissions positions were affected by the host variation more than the ones originating from the 4f 3 configuration as expected. The electronic energy of the 4f 2 5d configuration shifts to lower energy when increasing the crystal field. (author)

    Full Text Available La idea central del artículo es que la hipótesis de las líneas de fuga sencillamente orienta el problema general de las resistencias difusas. Se sostiene que abordar la cuestión de cómo cambian y se transforman las sociedades depende de acotar el terreno de la investigación más allá de los fenómenos de rechazo, inconformidad y divergencia colectiva. Desde ese punto de vista, se intenta diferenciar entre: i las campañas cuyo esfuerzo colectivo se traslada a la reivindicación política; ii las coaliciones en las reuniones públicas, los mítines, las manifestaciones, peticiones o declaraciones, procesiones solemnes y vigilias; y iii los fenómenos de innovación social. Se trata de mostrar que se puede considerar a los movimientos sociales en el contexto de situaciones decisivas de la transformación radical de la experiencia social ganando en una definición que excede la cuestión del activismo popular y la lucha por la transformación política del Estado. La naturaleza de la investigación es teórica, luego su metodología tiene que ver con el planteamiento general de la hipótesis filosófica de las líneas de fuga, en su compresión como orientación sociológica general.

    The elemental composition of fish otoliths can record the environmental information because once a trace element is deposited in the otolith; it presents a permanent record of the environmental conditions experienced by the fish at a particular time. The elemental signature of the otolith nucleus, the area lying within the first annual growth ring, is likely to be characteristic of the nursery areas of the species, and could be used as biological tracer for tracking origin and dispersal. However, ocean acidification may alter otolith growth and element incorporation, and it is important to establish baseline information about the sources of variation - both biotic and abiotic. The objectives of this study, as part of the wider CalMarO network, is to examine the regional differences in the otolith cores of selected fish species, contrast these differences with those measured between these same species in areas where their larvae co-exist and to find out the maternal effect to the chemical composition during the first forming of otoliths. The laboratory and field experiments were included to produce otolith material reflecting the maternal and regional patterns. Otolith composition was measured using laser-ablation ICPMS. For clarifying the regional patterns, juveniles from six locations and seven spawning groups along the west of the British Isles and larvae from the North Sea were sampled to distinguish the origin of spawning herring. There are three main nursery-ground groups, the Irish Sea, Scottish sea lochs and the Minch, contributing to the spawning herring in the west of the British Isles according to the otolith elemental composition data. However, the spawning origin of the North Sea herring larvae was still unclear. The otolith concentrations of Li, Na, Mg, Mn, Cu, Ru and Sr were significantly different among nursery-ground populations. Together with length-at-age data, at least two nursery-ground groups contributed to each spawning population. The

  18. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Australia

    In Australia most exploration for uranium has been conducted by companies and individuals. The geological mapping and airborne radiometric surveying conducted by the BMR is made available to interested persons. Exploration for uranium in Australia can be divided into two periods - 1947 to 1961 and 1966-1977. During the first period the Commonwealth Government introduced measures to encourage uranium exploration including a system of rewards for the discovery of uranium ore. This reward system resulted in extensive activity by prospectors particularly in the known mineral fields. Equipped with a Geiger counter or scintillometer, individuals with little or no experience in prospecting could compete with experienced prospectors and geologists. During this period several relative small uranium deposits were discovered generally by prospectors who found outcropping mineralisation. The second phase of uranium exploration in Australia began in 1966 at which time reserves amounted to only 6,200 tonnes of uranium and by 3 977 reserves had been increased to 289,000 tonnes. Most of the exploration was done by companies with substantial exploration budgets utilising more advanced geological and geophysical techniques. In the field of airborne radiometer the development of multi-channel gamma ray spectrometers with large volume crystal detectors increased the sensitivity of the tool as a uranium detector and resulted in several major discoveries. Expenditure or exploration for uranium increased from 1966 to 1971 but has declines in recent years. After listing the major geological elements of Australia, its uranium production and resources are discussed. During the period 1954-71 the total production of uranium concentrate in Australia amounted to 7,780 tonnes of uranium, and was derived from deposits at Rum Jungle (2,990 tonnes U) and the South Alligator River (610 tonnes U) in the Northern Territory, Mary Kathleen (3,460 tonnes U) in Queensland and Radium Hill (720 tonnes U

Despite this, youth with HIV are still at risk for increased mortality and morbidity compared with their uninfected counterparts. In developing countries, high numbers of youth die from acquired immune deficiency syndrome (AIDS-related illnesses due to lack of access to consistent antiretroviral treatment. As a result, pediatric palliative care is a relevant topic for those providing care to youth with HIV. A systematic review was conducted to gather information regarding the status of the literature related to pediatric palliative care and medical decision-making for youth with HIV. The relevant literature published between January 2002 and June 2012 was identified through searches conducted using PubMed, CINAHL, Scopus, and PSYCInfo databases and a series of key words. Articles were reviewed by thematic analysis using the pillars of palliative care set out by the National Consensus Project. Twenty-one articles were retained after review and are summarized by theme. In general, few empirically based studies evaluating palliative care and medical decision-making in youth with HIV were identified. Articles identified focused primarily on physical aspects of care, with less attention paid to psychological, social, ethical, and cultural aspects of care. We recommend that future research focuses on broadening the evaluation of pediatric palliative care among youth with HIV by directly evaluating the psychological, social, ethical, and cultural

    Mutations in BRCA1, BRCA2, ATM, TP53, CHK2 and PTEN account for many, but not all, multiple-case breast and ovarian cancer families. The histone acetyltransferase gene EP300 may function as a tumour suppressor gene because it is sometimes somatically mutated in breast, colorectal, gastric and pancreatic cancers, and is located on a region of chromosome 22 that frequently undergoes loss of heterozygosity in many cancer types. We hypothesized that germline mutations in EP300 may account for some breast cancer families that include cases of gastric, pancreatic and/or colorectal cancer. We screened the entire coding region of EP300 for mutations in the youngest affected members of 23 non-BRCA1/BRCA2 breast cancer families with at least one confirmed case of gastric, pancreatic and/or colorectal cancer. These families were ascertained in Australia through the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer. Denaturing HPLC analysis identified a heterozygous alteration at codon 211, specifically a GGC to AGC (glycine to serine) alteration, in two individuals. This conservative amino acid change was not within any known functional domains of EP300. The frequency of the Ser211 variant did not differ significanlty between a series of 352 breast cancer patients (4.0%) and 254 control individuals (2.8%; P = 0.5). The present study does not support a major role for EP300 mutations in breast and ovarian cancer families with a history of gastric, pancreatic and/or colorectal cancer

Awareness of the disease and biologic therapies, patient satisfaction and adherence, and physician (provider relationships were also assessed.Background: CD is a chronic, inflammatory, autoimmune disorder of the gastrointestinal tract that substantially impacts patients’ physical and emotional well-being. For patients eligible for biologic therapy, anti-tumor necrosis factor agents represent an important addition to the available therapies for CD.Methods: The study sample included biologic-naïve and biologic-experienced patients who had self-reported moderate to severe CD, were under the care of a specialist, and agreed to film a video diary and participate in a focus group. Data from the videos and group interviews were collected from May to June of 2009 and summarized qualitatively by grouping similar answers and quotations.Results: Of the 44 participants who submitted video diaries, 23 were biologic-experienced and 21 were biologic-naïve. Participants stated that CD caused fear and embarrassment, that they were reluctant to share the full impact of CD with family and providers, and that they relied on their provider for treatment decisions. Many participants accepted a new state of normalcy if their current medication helped their most bothersome symptoms without providing sustained remission. Participants receiving biologic therapy generally were more informed, more satisfied, and more likely to adhere to treatment regimens.Conclusion: Participants’ responses suggest a need for more patient education and more collaborative relationships between patients and

We tested the postulate that α-1 antitrypsin (A1AT polymorphism and the consequent deficiency of this antiprotease in humans are associated with a systemic disruption in iron homeostasis. Archived plasma samples from Alpha-1 Foundation (30 MM, 30 MZ, and 30 ZZ individuals were analyzed for A1AT, ferritin, transferrin, and C-reactive protein (CRP. Plasma samples were also assayed for metals using inductively coupled plasma atomic emission spectroscopy (ICPAES. Plasma levels of A1AT in MZ and ZZ individuals were approximately 60% and 20% of those for MM individuals respectively. Plasma ferritin concentrations in those with the ZZ genotype were greater relative to those individuals with either MM or MZ genotype. Plasma transferrin for MM, MZ, and ZZ genotypes showed no significant differences. Linear regression analysis revealed a significant (negative relationship between plasma concentrations of A1AT and ferritin while that between A1AT and transferrin levels was not significant. Plasma CRP concentrations were not significantly different between MM, MZ, and ZZ individuals. ICPAES measurement of metals confirmed elevated plasma concentrations of nonheme iron among ZZ individuals. Nonheme iron concentrations correlated (negatively with levels of A1AT. A1AT deficiency is associated with evidence of a disruption in iron homeostasis with plasma ferritin and nonheme iron concentrations being elevated among those with the ZZ genotype.Keywords: α-1

    Do women with ITALIC! BRCA1 or ITALIC! BRCA2 mutations have reduced ovarian reserve, as measured by circulating anti-Müllerian hormone (AMH) concentration? Women with a germline mutation in ITALIC! BRCA1 have reduced ovarian reserve as measured by AMH. The DNA repair enzymes encoded by ITALIC! BRCA1 and ITALIC! BRCA2 are implicated in reproductive aging. Circulating AMH is a biomarker of ovarian reserve and hence reproductive lifespan. This was a cross-sectional study of AMH concentrations of 693 women at the time of enrolment into the Kathleen Cuningham Foundation Consortium for research in the Familial Breast Cancer (kConFab) cohort study (recruitment from 19 August 1997 until 18 September 2012). AMH was measured on stored plasma samples between November 2014 and January 2015 using an electrochemiluminescence immunoassay platform. Eligible women were from families segregating ITALIC! BRCA1 or ITALIC! BRCA2 mutations and had known mutation status. Participants were aged 25-45 years, had no personal history of cancer, retained both ovaries and were not pregnant or breastfeeding at the time of plasma storage. Circulating AMH was measured for 172 carriers and 216 non-carriers from families carrying ITALIC! BRCA1 mutations, and 147 carriers and 158 non-carriers from families carrying ITALIC! BRCA2 mutations. Associations between plasma AMH concentration and carrier status were tested by linear regression, adjusted for age at plasma storage, oral contraceptive use, body mass index and cigarette smoking.

Recombinant subunit vaccines are an attractive alternative for pandemic vaccines compared to traditional vaccine technologies. In particular, polyanhydride nanoparticles encapsulating subunit proteins have been shown to enhance humoral and cell-mediated immunity and provide protection upon lethal challenge. In this work, a recombinant H5 hemagglutinin trimer (H53 was produced and encapsulated into polyanhydride nanoparticles. The studies performed indicated that the recombinant H53 antigen was a robust immunogen. Immunizing mice with H53 encapsulated into polyanhydride nanoparticles induced high neutralizing antibody titers and enhanced CD4+ T cell recall responses in mice. Finally, the H53-based polyanhydride nanovaccine induced protective immunity against a low-pathogenic H5N1 viral challenge. Informatics analyses indicated that mice receiving the nanovaccine formulations and subsequently challenged with virus were similar to naïve mice that were not challenged. The current studies provide a basis to further exploit the advantages of polyanhydride nanovaccines in pandemic scenarios. Keywords: polymer, nanoparticle, vaccine, subunit

Materials and methods: A blend (BL of Aloe vera-based Nerium oleander extract (NAE-8i, oleandrin-free and hydrolyzed water-soluble egg membrane (WSEM was applied to human whole-blood cultures for 24 hours, with each separate ingredient serving as a control. Immune-cell subsets were analyzed for expression levels of the activation markers CD69 and CD25. Culture supernatants were analyzed for cytokines, chemokines, and immunoregulating peptides. Results: BL increased CD69 expression on lymphocytes, monocytes, and CD3–CD56+ natural killer cells, and CD25 expression on natural killer cells. The number of CD69+CD25+ lymphocytes increased in cultures treated with BL and the separate ingredients. BL triggered production of multiple cytokines and chemokines, where CC chemokines MIP1α and MIP3α, as well as cytokines involved in wound healing – Groα, Groβ, ENA78, and fractalkine – reached levels manyfold above treatment with either NAE-8i or WSEM alone. Conclusion: Data on BL showed that WSEM strongly enhanced NAE-8i’s effects on immunoactivation in vitro. This has potential relevance for support of immunity in skin tissue, including antibacterial and antiviral defense mechanisms, wrinkle reduction, and wound care.

The objective of this study was to elicit patient preferences for attributes associated with antivascular endothelial growth factor, focal and panretinal laser, and steroid therapy used in DR management.Methods: A cross-sectional conjoint survey was administered to DR patients at three Canadian eye centers. The survey involved making tradeoffs among 11 DR treatment attributes, including the chance of improving vision and risks of adverse events over a 1-year treatment period. Attribute utilities were summed for each product profile to determine the most preferred treatment.Results: Based on the results from 161 patients, attributes affecting visual functioning, including improving visual acuity and reducing adverse events (eg, chance of cataracts, were more important than those not directly affecting vision (eg, administration. Overall, 52%, 20%, 17%, and 11% preferred the product profiles matching to the antivascular endothelial growth factor, steroid, focal laser, and panretinal laser therapies.

    Full Text Available Roger K Cady, Kathleen Farmer Headache Care Center, Springfield, MO, USA Abstract: For the last quarter of a century, triptans have been available for acute treatment of migraine but with little guidance on which of the different triptan products to use for which patient or which attack of migraine. In this article, we propose a structured approach to analysis of individual migraine attacks and patient characteristics as a means of defining and optimizing acute intervention. Assessment of patient and attack profiles includes the “5-Ps”: pattern, phenotype, patient, pharmacology, and precipitants. Attending to these five components of information can assist in developing an individualized behavioral, pharmacological, and nonpharmacological comprehensive treatment plan for most migraine patients. This clinical approach is then focused on frovatriptan because of its unique molecular signature and potential novel clinical applications. Frovatriptan like all triptans is indicated for acute treatment of migraine but its role has been explored in management of several unique migraine phenotypes. Frovatriptan has the longest half-life of any triptan and consequently is often promoted for acute treatment of migraine of longer duration. It has also been studied as a short-term preventive treatment in women with menstrual-related migraine. Given that 60% of female migraineurs suffer from menstrual-related migraine, this population is the obvious group for continued study. Small studies have also explored frovatriptan’s use in treating migraine predicted by premonitory symptoms as a preventive for the headache phase of migraine. By identifying patient and attack profiles, clinicians may effectively determine the viability of frovatriptan as an effective pharmacological intervention for migraine.

    Recent outbreaks of Zika virus around the world led to increased discussions about this issue on social media platforms such as Twitter. These discussions may provide useful information about attitudes, knowledge, and behaviors of the population regarding issues that are important for public policy. We sought to identify the associations of the topics of discussions on Twitter and survey measures of Zika-related attitudes, knowledge, and behaviors, not solely based upon the volume of such discussions but by analyzing the content of conversations using probabilistic techniques. Using probabilistic topic modeling with US county and week as the unit of analysis, we analyzed the content of Twitter online communications to identify topics related to the reported attitudes, knowledge, and behaviors captured in a national representative survey (N=33,193) of the US adult population over 33 weeks. Our analyses revealed topics related to "congress funding for Zika," "microcephaly," "Zika-related travel discussions," "insect repellent," "blood transfusion technology," and "Zika in Miami" were associated with our survey measures of attitudes, knowledge, and behaviors observed over the period of the study. Our results demonstrated that it is possible to uncover topics of discussions from Twitter communications that are associated with the Zika-related attitudes, knowledge, and behaviors of populations over time. Social media data can be used as a complementary source of information alongside traditional data sources to gauge the patterns of attitudes, knowledge, and behaviors in a population. ©Mohsen Farhadloo, Kenneth Winneg, Man-Pui Sally Chan, Kathleen Hall Jamieson, Dolores Albarracin.

Data were collected through a 15-minute online survey of 910 US wine drinkers randomly selected from a panel of consumers. It was found that the “super core” segment not only drank wine more frequently, but also were more likely to drink other types of alcohol presented (beer, distilled spirits, and ready-to-drink cocktails, and at a greater frequency, “at least once a week” and “about once a week”, than “marginal” drinkers. Differences between usage rate segments existed between sex and age generations. Female millennial “super core” consumers would increase wine consumption if the number of calories were reduced to fewer than 80 per 5 oz serving. Practical implications for a winery or wine retailer might include the potential to add these beverages to their product offering or bundling these beverages to create packages (allowing for mass customization, which is used often in retail and appropriately marketing these offerings to their customers. Changes that may invoke a positive response are wine made from “sustainably farmed” or “naturally farmed” grapes, and certified carbon-free wine. From an originality viewpoint, this study is the first to investigate how usage rate segmentation can be enriched by means of variable cross-extension and examination.

    There is a rising need for scientifically sound and quantitative as well as simple, rapid, cheap and readily available soil testing procedures. The purpose of this study was to explore selected soft drinks (Coca-Cola Classic®, Diet Coke®, Coke Zero®) as indicators of bioaccessible uranium and other trace elements (As, Ce, Cu, La, Mn, Ni, Pb, Th, Y, Zn) in contaminated soils of the Mary Kathleen uranium mine site, Australia. Data of single extraction tests using Coca-Cola Classic®, Diet Coke® and Coke Zero® demonstrate that extractable arsenic, copper, lanthanum, manganese, nickel, yttrium and zinc concentrations correlate significantly with DTPA- and CaCl₂-extractable metals. Moreover, the correlation between DTPA-extractable uranium and that extracted using Coca-Cola Classic® is close to unity (+0.98), with reduced correlations for Diet Coke® (+0.66) and Coke Zero® (+0.55). Also, Coca-Cola Classic® extracts uranium concentrations near identical to DTPA, whereas distinctly higher uranium fractions were extracted using Diet Coke® and Coke Zero®. Results of this study demonstrate that the use of Coca-Cola Classic® in single extraction tests provided an excellent indication of bioaccessible uranium in the analysed soils and of uranium uptake into leaves and stems of the Sodom apple (Calotropis procera). Moreover, the unconventional reagent is superior in terms of availability, costs, preparation and disposal compared to traditional chemicals. Contaminated site assessments and rehabilitation of uranium mine sites require a solid understanding of the chemical speciation of environmentally significant elements for estimating their translocation in soils and plant uptake. Therefore, Cola soft drinks have potential applications in single extraction tests of uranium contaminated soils and may be used for environmental impact assessments of uranium mine sites, nuclear fuel processing plants and waste storage and disposal facilities.

    This report describes options for monitoring the status and population trends of the golden eagle (Aquila chrysaetos) within the Desert Renewable Energy Conservation Plan (DRECP) area of Southern California in maintaining stable or increasing population in the planning area. The report profiles the ecology of golden eagles in the region and provides a range of potential sampling options to address monitoring needs and objectives. This approach also focused on links between changes in human land-use, golden eagle nesting and foraging habitat conditions, and population dynamics. The report outlines how monitoring data from demographic, prey, and habitat studies were used to develop a predictive demographic model for golden eagles in the DRECP area. Results from the model simulations suggest increases in renewable energy development could have negative consequences for population trajectories. Results also suggest site-specific conservation actions could reduce the magnitude of negative impacts to the local population of eagles. A monitoring framework is proposed including: (1) annual assessments of site-occupancy and reproduction by territorial pairs of golden eagles (including rates at which sites become colonized or vacated over time); (2) estimates of survival, movements, and intensity of use of landscapes by breeding and non-breeding golden eagles; (3) periodic (conducted every two to four years) assessments of nesting and foraging habitats, prey populations, and associations with land-use and management activities; and (4) updating the predictive demographic model with new information obtained on eagles and associated population stressors. The results of this research were published in the Journal of Rapture Research, Wiens, David,Inman, Rich D., Esque, Todd C., Longshore, Kathleen M. and Nussear, Kenneth (2017).

    Cheryl Hailstrom, the CEO of Lakeland Wonders, a manufacturer of high-quality wooden toys, is the first person outside the Swensen family to hold the top job. But she's not a stranger to this 94-year-old company: She'd been the COO of one of its largest customers and had worked with Lakeland to develop many best-selling products. Wally Swensen IV, the previous CEO, chose Cheryl because she knew how to generate profits and because he believed her energy and enthusiasm could take the company to the next level. Yet here she is, nearing her six-month anniversary, wondering why her expansive vision for the company isn't taking hold. She's tried to lead by example: traveling a pounding schedule to visit customers, setting aggressive project deadlines, and proposing a bonus schedule. She has a plan to reach the board's growth goals--going beyond Lakeland's core upscale market and launching into the midmarket with an exclusive toy contract with a new customer. The problem is that while Cheryl's senior managers are giving her the nod on the surface, they're all really dragging their feet. Some fear that offshore outsourcing will hurt their brand, not to mention make for tricky union negotiations. Others are balking at trying a new design firm. Is Cheryl pushing too much change too quickly? Should she bring in outsiders to speedily adopt the changes she envisions and overhaul Lakeland's corporate culture? Or should she keep trying to work with the current team? Commentators Kathleen Calcidise of Apple Retail Stores; executive coach Debra Benton; Dan Cohen, coauthor of The Heart of Change; and consultant Nina Aversano offer advice in this fictional case study.

    Full Text Available Kathleen A Bieryla, Neil M DoldBiomedical Engineering Department, Bucknell University, Lewisburg, PA, USABackground and purpose: Numerous interventions have been proposed to improve balance in older adults with varying degrees of success. A novel approach may be to use an off-the-shelf video game system utilizing real-time force feedback to train older adults. The purpose of this study is to investigate the feasibility of using Nintendo's Wii Fit for training to improve clinical measures of balance in older adults and to retain the improvements after a period of time.Methods: Twelve healthy older adults (aged >70 years were randomly divided into two groups. The experimental group completed training using Nintendo's Wii Fit game three times a week for 3 weeks while the control group continued with normal activities. Four clinical measures of balance were assessed before training, 1 week after training, and 1 month after training: Berg Balance Scale (BBS, Fullerton Advanced Balance (FAB scale, Functional Reach (FR, and Timed Up and Go (TUG. Friedman two-way analysis of variance by ranks was conducted on the control and experimental group to determine if training using the Wii Balance Board with Wii Fit had an influence on clinical measures of balance.Results: Nine older adults completed the study (experimental group n = 4, control group n = 5. The experimental group significantly increased their BBS after training while the control group did not. There was no significant change for either group with FAB, FR, and TUG.Conclusion: Balance training with Nintendo's Wii Fit may be a novel way for older adults to improve balance as measured by the BBS.Keywords: older adults, balance, training

Prior to and after fistula repair surgery, social support can help a woman to reintegrate into her community. The aim of this study was to preliminarily examine the experiences of social support among Tanzanian women presenting with obstetric fistula in the periods immediately preceding obstetric fistula repair surgery and following reintegration.Patients and methods: The study used a mixed-methods design to analyze cross-sectional surveys (n=59 and in-depth interviews (n=20.Results: Women reported widely varying levels of social support from family members and partners, with half of the sample reporting overall high levels of social support. For women experiencing lower levels of support, fistula often exacerbated existing problems in relationships, sometimes directly causing separation or divorce. Many women were assertive and resilient with regard to advocating for their fistula care and relationship needs.Conclusion: Our data suggest that while some women endure negative social experiences following an obstetric fistula and require additional resources and services, many women report high levels of social support from family members and partners, which may be harnessed to improve the holistic

    Full Text Available Abstract Men who carry mutations in BRCA1 or BRCA2 are at increased risk for prostate cancer. However the efficacy of prostate screening in this setting is uncertain and limited data exists on the uptake of prostate screening by mutation carriers. This study prospectively evaluated uptake of prostate cancer screening in a multi-institutional cohort of mutation carriers. Subjects were unaffected male BRCA1 and BRCA2 mutation carriers, aged 40–69 years, enrolled in the Kathleen Cuningham Consortium for Research into Familial Breast Cancer (kConFab and who had completed a mailed, self-report follow-up questionnaire 3 yearly after study entry. Of the 75 male carriers in this study, only 26 (35% had elected to receive their mutation result. Overall, 51 (68% did not recall having received a recommendation to have prostate screening because of their family history, but 41 (55% had undergone a prostate specific antigen (PSA test and 32 (43% a digital rectal examination (DRE in the previous 3 years. Those who were aware of their mutation result were more likely to have received a recommendation for prostate screening (43 vs. 6%, p = 0.0001, and to have had a PSA test (77 vs. 43%, p = 0.005 and a DRE (69 vs. 29%, p = 0.001 in the previous 3 years. The majority of unaffected males enrolled in kConFab with a BRCA1/2 mutation have not sought out their mutation result. However, of those aware of their positive mutation status, most have undergone at least one round of prostate screening in the previous 3 years.

    The success of Yahoo!, eBay, Enron, and other companies that have become adept at morphing to meet the demands of changing markets can't be explained using traditional thinking about competitive strategy. These companies have succeeded by pursuing constantly evolving strategies in market spaces that were considered unattractive according to traditional measures. In this article--the third in an HBR series by Kathleen Eisenhardt and Donald Sull on strategy in the new economy--the authors ask, what are the sources of competitive advantage in high-velocity markets? The secret, they say, is strategy as simple rules. The companies know that the greatest opportunities for competitive advantage lie in market confusion, but they recognize the need for a few crucial strategic processes and a few simple rules. In traditional strategy, advantage comes from exploiting resources or stable market positions. In strategy as simple rules, advantage comes from successfully seizing fleeting opportunities. Key strategic processes, such as product innovation, partnering, or spinout creation, place the company where the flow of opportunities is greatest. Simple rules then provide the guidelines within which managers can pursue such opportunities. Simple rules, which grow out of experience, fall into five broad categories: how- to rules, boundary conditions, priority rules, timing rules, and exit rules. Companies with simple-rules strategies must follow the rules religiously and avoid the temptation to change them too frequently. A consistent strategy helps managers sort through opportunities and gain short-term advantage by exploiting the attractive ones. In stable markets, managers rely on complicated strategies built on detailed predictions of the future. But when business is complicated, strategy should be simple.

    Germline mutations in the genes BRCA1 and BRCA2 account for only a proportion of hereditary breast cancer, suggesting that additional genes contribute to hereditary breast cancer. Recently a heterozygous variant in the ataxia–telangiectasia mutated (ATM) gene, IVS10-6T→G, was reported by an Australian multiple-case breast cancer family cohort study (the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer) to confer a substantial breast cancer risk. Although this variant can result in a truncated ATM product, its clinical significance as a high-penetrance breast cancer allele or its role as a low-penetrance risk-modifier is controversial. We determined the frequency of ATM IVS10-6T→G variants in a cohort of individuals affected by breast and/or ovarian cancer who underwent BRCA1 and BRCA2 genetic testing at four major Australian familial cancer clinics. Seven of 495 patients (1.4%) were heterozygous for the IVS10-6T→G variant; the carrier rate in unselected Australian women with no family history of breast cancer is reported to be 6 of 725 (0.83%) (P = 0.4). Two of the seven probands also harboured a pathogenic BRCA1 mutation and one patient had a BRCA1 unclassified variant of uncertain significance. These findings indicate that the ATM IVS10-6T→G variant does not seem to occur at a significantly higher frequency in affected individuals from high-risk families than in the general population. A role for this variant as a low-penetrance allele or as a modifying gene in association with other genes (such as BRCA1) remains possible. Routine testing for ATM IVS10-6T→G is not warranted in mutation screening of affected individuals from high-risk families

    Electronic word-of-mouth on social network sites has been used successfully in marketing. In social marketing, electronic word-of-mouth about products as health behaviors has the potential to be more effective and reach more young adults than health education through traditional mass media. However, little is known about what motivates people to actively initiate electronic word-of-mouth about health behaviors on their personal pages or profiles on social network sites, thus potentially reaching all their contacts on those sites. This study filled the gap by applying a marketing theoretical model to explore the factors associated with electronic word-of-mouth on social network sites about leisure-time physical activity. A Web survey link was sent to undergraduate students at one of the Midwestern universities and 439 of them completed the survey. The average age of the 439 participants was 19 years (SD=1 year, range: 18-24). Results suggested that emotional engagement with leisure-time physical activity (ie, affective involvement in leisure-time physical activity) predicted providing relevant opinions or information on social network sites. Social network site users who perceived stronger ties with all their contacts were more likely to provide and seek leisure-time physical activity opinions and information. People who provided leisure-time physical activity opinions and information were more likely to seek opinions and information, and people who forwarded information about leisure-time physical activity were more likely to chat about it. This study shed light on the application of the electronic word-of-mouth theoretical framework in promoting health behaviors. The findings can also guide the development of future social marketing interventions using social network sites to promote leisure-time physical activity. ©Ni Zhang, Shelly Campo, Jingzhen Yang, Petya Eckler, Linda Snetselaar, Kathleen Janz, Emily Leary.

Unhealthy maternal lifestyle during pregnancy such as smoking, high prepregnancy body mass index (BMI as well as alcohol and caffeine intake may constitute possible risk factors for cryptorchidism, but results from the few previous studies are conflicting. We aimed to explore the association between maternal lifestyle factors and occurrence of cryptorchidism in sons.Patients and methods: The Danish National Birth Cohort and the Aarhus Birth Cohort provided information on maternal lifestyle from early pregnancy. Data were linked to several Danish health registers, multiple imputation was used to handle missing data and Cox proportional hazards models were used to adjust for potential confounders.Results: In total, 85,923 boys were included, and of them, 2.2% were diagnosed with cryptorchidism. We observed the strongest associations between maternal tobacco smoking and prepregnancy BMI and cryptorchidism. Sons of women who smoked 10–14 cigarettes/day had the highest hazard ratio (HR for cryptorchidism (1.37; 95% CI: 1.06–1.76, and for maternal BMI ≥30 kg/m2, the HR was 1.32 (95% CI: 1.06–1.65.

    Design and technical advancements in sensing, processing, and wireless communication capabilities of small, portable devices known as wireless sensor nodes (WSNs) have drawn extensive research attention and are vastly applied in science and engineering applications. The WSNs are typically powered by a chemical battery source that has a load dependent finite lifetime. Most applications, including the nuclear industry applications, require WSNs to operate for an extended period of time beginning with their deployment. To ensure longevity, it is important to develop self-powered WSNs. The benefit of self-powered WSNs goes far beyond the cost savings of removing the need for cable installation and maintenance. Self-powered WSNs will potentially offer significant expansion in remote monitoring of nuclear facilities, and provide important data on plant equipment and component status during normal operation, as well as in case of abnormal operation, station blackouts or post-accident evaluation. Advancements in power harvesting technologies enable electric energy generation from many sources, including kinetic, thermal, and radiated energy. For the ongoing research at Idaho National Laboratory, a solid-state thermoelectric-based technology, the thermoelectric generator (TEG), is used to convert thermal energy to power a WSN. The design and development of TEGs to power WSNs that would remain active for a long period of time requires comprehensive understanding of WSN operational. This motivates the research in modeling the lifetime, i.e., power consumption, of a WSN by taking into consideration various node and network level activities. A WSN must perform three essential tasks: sense events, perform quick local information processing of sensed events, and wirelessly exchange locally processed data with the base station or with other WSNs in the network. Each task has a power cost per unit tine and an additional cost when switching between tasks. There are number of other

    To investigate the effects of Corydalis Rhizoma and L-tetrahydropalma-tine (L-THP) on the levels of dopamine neurotransmitter (DA), dopamine transporter (DAT) and the second dopamine receptor (D2R) in learning and memory-related brain areas, hippocampus and striatum, the DA, DAT and D2R were detected in conditioned place preference (CPP) rats suffered from morphine. And comparation the degree of similarity and consistency of the pharmacological effects was also studied. The rats were trained in black compartments and white ones (drug-paired compartment) with the increasing doses of morphine for 10 days (hypodermically injected from 10 mg•kg⁻¹ to 100 mg•kg⁻¹). Models of CPP were validated in those psychological dependence rats after 48 h training. The dopamine contents were detected as soon as the materials of hippocampus and striatum are harvested from rats of NS control group and model group. The DAT and D2R levels are measured by Western blot. The high, medium and low dose group of Corydalis Rhizoma are given Corydalis Rhizoma 2, 1, 0.5 g•kg⁻¹ water extraction liquid respectively (which contains L-THP were 0.274, 0.137 and 0.137 mg respectively), and the high, medium and low dose group of L-THP were given L-THP 3.76, 1.88, 0.94 mg•kg⁻¹ lavage treatment respectively, NS treatment group were lavaged normal saline for 6 days and they were killed after test of CPP, again tested DA levels and expression of DAT and D2R similar to the front of materials. The reduction effects of CPP were observed in the groups of both Corydalis Rhizoma (2, 1 g•kg⁻¹) and L-THP (3.76, 1.88 mg•kg⁻¹) subjected to medicine for 6 days (Peffect of L-THP. The similar effects were observed on the neurotransmitter dopamine, DAT and D2R in learning and memory-related brain areas, hippocampus and striatum of the morphine- dependent rats.

    This article describes a metrological, robotic hand to manipulate and measure micrometer size objects. The presented work demonstrates not only assembly operations, but also positioning control and metrology capability. Sample motion is achieved by a commercial positioning stage, which provides XYZ-displacements for assembly of components. A designed and manufactured gripper tool that incorporates 21 degrees-of-freedom for independent alignment of actuators, sensors, and the three fingers of this hand is presented. These fingers can be opened and closed by piezoelectric actuators through levered flexures providing an 80 μm displacement range measured with calibrated opto-interrupter based, knife-edge sensors. The operational ends of the fingers comprise of a quartz tuning fork with a 7 μm diameter 3.2 mm long carbon fiber extending from the end of one tuning fork tine. Finger-tip force-sensing is achieved by the monitoring of individual finger resonances typically at around 32 kHz. Experimental results included are focused on probe performance analysis. Pick and place operation using the three fingers is demonstrated with all fingers being continuously oscillated, a capability not possible with the previous single or two finger tweezer type designs. By monitoring electrical feedback during pick and place operations, changes in the response of the three probes demonstrate the ability to identify both grab and release operations. Component metrology has been assessed by contacting different micro-spheres of diameters 50(±7.5) μm, 135(±20) μm, and 140(±20) μm. These were measured by the micro robot to have diameters of 67, 133, and 126 μm respectively with corresponding deviations of 4.2, 4.9, and 4.3 μm. This deviation in the measured results was primarily due to the manual, joystick-based, contacting of the fingers, difficulties associated with centering the components to the axis of the hand, and lower contact sensitivity for the smallest sphere

    Most wireless sensor network (comprising of thousands of WSNs) applications require operation over extended periods of time beginning with their deployment. Network lifetime is extremely critical for most applications and is one of the limiting factors for energy-constrained networks. Based on applications, there are wide ranges of different energy sources suitable for powering WSNs. A battery is traditionally used to power WSNs. The deployed WSN is required to last for long time. Due to finite amount of energy present in batteries, it is not feasible to replace batteries. Recently there has been a new surge in the area of energy harvesting were ambient energy in the environment can be utilized to prolong the lifetime of WSNs. Some of the sources of ambient energies are solar power, thermal gradient, human motion and body heat, vibrations, and ambient RF energy. The design and development of TEGs to power WSNs that would remain active for a long period of time requires comprehensive understanding of WSN operational. This motivates the research in modeling the lifetime, i.e., power consumption, of a WSN by taking into consideration various node and network level activities. A WSN must perform three essential tasks: sense events, perform quick local information processing of sensed events, and wirelessly exchange locally processed data with the base station or with other WSNs in the network. Each task has a power cost per unit tine and an additional cost when switching between tasks. There are number of other considerations that must also be taken into account when computing the power consumption associated with each task. The considerations includes: number of events occurring in a fixed active time period and the duration of each event, event-information processing time, total communication time, number of retransmission, etc. Additionally, at the network level the communication of information data packets between WSNs involves collisions, latency, and

    On the theory of Board, Hall and Hall (1975) it should be possible, given a suitable trigger, to achieve a very efficient thermal explosion in which a self-sustaining shock wave passes through a course initial mixture, causes fine fragmentation. We describe briefly an experiment in which a rather dilute mixture of tine and water, confined in a strong tube, was triggered by a No. 6 detonator; the progress of the explosion was monitored by four pressure transducers in the tube wall. The Kistler 603B transducers were connected to an Ampex FR1300A tape recorder with 40 kHz bandwidth, in parallel with U/V recorder galvanometers of 5 kHz resonant frequency. The presence of the metal was detected by the shorting of two parallel meshes at the mouth of the tube. Detailed comparison between the tape recorded traces and those in the U/V recorder show good agreement, with no evidence of transient overload. We may make the following preliminary observations. The negative feature travelling at ∼10 5 cm/s is presumably a compression wave travelling on the walls of the strong tube. There are several reasons for thinking that substantial energy release took place in the region around transducer 2 (1 being the nearest to the detonator). Firstly we know from earlier visualisation experiments that the metal is concentrated (in ∼1/3 cm drops) in this region of the tube. Secondly the pressure-time integral under record 2 is substantially greater than that under 1. Thirdly the rise time of 100 μs for record 2 is of the order of that expected for collapse of a vapour blanket on a 1/3 cm drop under 60 bars overpressure. Further up the tube the pressure pulse decays slightly, and also steepens; this is consistent with there being considerably less vapour and metal in this region. In the total volume of the tube (600 cc) there are ∼100 cc of metal - assuming an equal quantity of vapour, and a mean front velocity of 5 x 10 4 cm/s we find a differential velocity of ∼ 10 4 cm/s, which

    We studied 22 AIDS patients who presented musculoskeletal system pathology. The affected area underwent simple X-ray and MR. The MR study was performed using a 1 Tesla magnet. T1 and T2 weighted echo spin sequences, as well as sequences of short T1 inversion recovery (STIR). In nine cases, intravenous gadolinium was used at a dose of 0.2cc/kg. The study plane was selected depending on the location of the lesion and surface coils were used when appropriate. In those patients showing pathology which was removed from the appendicular skeleton, the principal magnet was used as both transmitter and receiver. In one case, an On-Tine Tomography (CT) was also carried out. The evaluated ata were: a) localization; b) bony erosion; c) soft-tissue mass; d) articular effusion; e) cartilaginous changes; f) and T2 signals, and g) gadolinium enhancement. A diagnosis was made on the basis of biopsy or clinical culture, and evolution. Spinal cord alterations were the most frequent, being found in 13 cases. Twelve were caused by spondylodiscitis, 10 by tuberculosis, one by staphylococcal infection and one by candidiasis. In all cases, there appeared disk damage, as well as bone marrow signal alterations in the affected area and disks soft-tissue. In the mine cases in which gadolinium was used, the disk, vertebral plates and cases in which gadolinium was used, the disk, vertebral plates and soft-tissue mass heterogeneously enhanced, demonstrating an abscess with ring enhancement, and a central necrotic area in one case. In one patient, a spinal cord alteration due to non-Hodgkin's lymphoma was observed. In six cases,there was observed and infectious arthritis two in coxofemoral joints, three in knees and one in a glenohumeral joint. Isolated germs were staphylococcal in three cases one being Mycobacterium tuberculosis, another being M. kansasii and the third identified as. Candida. In all cases, there was observed joint effusion, synovial thickening, joint cartilage damage and

    In the field of 3D airborne electromagnetic (AEM) modeling, both finite-difference time-domain (FDTD) method and finite-element time-domain (FETD) method have limitations that FDTD method depends too much on the grids and time steps, while FETD requires large number of grids for complex structures. We propose a time-domain spectral-element (SETD) method based on GLL interpolation basis functions for spatial discretization and Backward Euler (BE) technique for time discretization. The spectral-element method is based on a weighted residual technique with polynomials as vector basis functions. It can contribute to an accurate result by increasing the order of polynomials and suppressing spurious solution. BE method is a stable tine discretization technique that has no limitation on time steps and can guarantee a higher accuracy during the iteration process. To minimize the non-zero number of sparse matrix and obtain a diagonal mass matrix, we apply the reduced order integral technique. A direct solver with its speed independent of the condition number is adopted for quickly solving the large-scale sparse linear equations system. To check the accuracy of our SETD algorithm, we compare our results with semi-analytical solutions for a three-layered earth model within the time lapse 10-6-10-2s for different physical meshes and SE orders. The results show that the relative errors for magnetic field B and magnetic induction are both around 3-5%. Further we calculate AEM responses for an AEM system over a 3D earth model in Figure 1. From numerical experiments for both 1D and 3D model, we draw the conclusions that: 1) SETD can deliver an accurate results for both dB/dt and B; 2) increasing SE order improves the modeling accuracy for early to middle time channels when the EM field diffuses fast so the high-order SE can model the detailed variation; 3) at very late time channels, increasing SE order has little improvement on modeling accuracy, but the time interval plays

    Full Text Available El imaginario de los “campesinos” es muy impregnado por figuras místico-míticas que tienen una profunda influencia en la formación de su ethos social. Folclorificadas o reales, hacen influencia individual y socialmente - aunque no necesariamente consciente de ese poder – en una miríada de “devotos”, en el sentido lato, en el cotidiano representativo de su tierra/identidad: el “campo”. Esta participación se entrelaza entre diversas corrientes: eclesial, cultural, religioso, transcendental, etc, donde no siempre hacen un dialogo conceptual, fenomenal o institucional o no están de acuerdo y luchan cuando plantean cuestiones de los dominios de territorialidad religiosas, cuyos lideres y/o portadores de “vínculos sobrenaturales” dictan lo que seguir. Esta influencia es personal o de forma remota, transmitido de generación en generación, de manera inculturada o autóctonas y tiene su origen en la Heteronomía, que forjó el imaginario religioso de lo “campesino”. El poder de persuasión es explorado en varias áreas desde la política a la religión, del académico al social, del individuo a las masas. Ha sido canalizado en el trabajo social como para influir en las campañas y mítines electorales; en la identidad del “campesino” a una cultura líquida; en la solidificación del analfabetismo político en la educación contextualizada en regiones semiáridas; una fe esclarecida a una práctica religiosa irracional e irresponsable.

  11. Critical factors which shaped Iranian cities in History

    The history of Iranian Cities and its associated urban a paces are long and colourful. the role of urban areas has always been an important one. It is important for the purpose at hand, to examine, albeit in a cursory fashion, some of critical factors which shaped the development of Iranian Cities, including urban spaces. Moreover, I believe that these forces created, in Iran, a variable, rational urban system and that the currency set of p roblems i n Iranian Cities results from new technological forces interacting with l der, historical forces. Of course, making generalizations about Persian towns is at best, a risky business, The wide range of natural and historical forces which have played across the face of this country have created special conditions in each urban settlement. But, in spite of the fact that each Persian town has a distinct character and ambience, one can easily see that these differences occur within a framework which is remarkably similar in both basic principles and details. Now, however, even greater forces are operating in Iran, as all over the world, to alter towns almost beyond recognition. The internal combustion engine is introducing a new scale of distance to the city; telecommunications are giving the city a new time scale; industrialization is challenging the traditional economic bases of cities. Tine and again, for both the East and West, these new forces have overwhelmed the more modest human scale of old towns. Times and again, planners and administrators have realized very late in the process that the other scales must be preserved as well. Iran is no exception. This article offers some suggestion as to how Iranian planners and administrators might preserve the human scale in Persian towns. It begins with a look at the history of Persian towns in an attempt to define (implicitly) the Persian human scale by describing the rational urban systems and details which developed in Iran over some 5,000 years of urbanisation.

    We studied 22 AIDS patients who presented musculoskeletal system pathology. The affected area underwent simple X-ray and MR. The MR study was performed using a 1 Tesla magnet. T1 and T2 weighted echo spin sequences, as well as sequences of short T1 inversion recovery (STIR). In nine cases, intravenous gadolinium was used at a dose of 0.2cc/kg. The study plane was selected depending on the location of the lesion and surface coils were used when appropriate. In those patients showing pathology which was removed from the appendicular skeleton, the principal magnet was used as both transmitter and receiver. In one case, an On-Tine Tomography (CT) was also carried out. The evaluated ata were: a) localization; b) bony erosion; c) soft-tissue mass; d) articular effusion; e) cartilaginous changes; f) and T2 signals, and g) gadolinium enhancement. A diagnosis was made on the basis of biopsy or clinical culture, and evolution. Spinal cord alterations were the most frequent, being found in 13 cases. Twelve were caused by spondylodiscitis, 10 by tuberculosis, one by staphylococcal infection and one by candidiasis. In all cases, there appeared disk damage, as well as bone marrow signal alterations in the affected area and disks soft-tissue. In the mine cases in which gadolinium was used, the disk, vertebral plates and cases in which gadolinium was used, the disk, vertebral plates and soft-tissue mass heterogeneously enhanced, demonstrating an abscess with ring enhancement, and a central necrotic area in one case. In one patient, a spinal cord alteration due to non-Hodgkin's lymphoma was observed. In six cases,there was observed and infectious arthritis two in coxofemoral joints, three in knees and one in a glenohumeral joint. Isolated germs were staphylococcal in three cases one being Mycobacterium tuberculosis, another being M. kansasii and the third identified as. Candida. In all cases, there was observed joint effusion, synovial thickening, joint cartilage damage and bony

    Nonuniform current distribution is generated in a conductor consisting of strands coated by a high resistive layer, such as chromium plating, as a result of superimposition of transport and induce circulation currents. The characteristics of the induced circulation current are analytically studied by using a distributed model circuit. The parameters mostly used in this calculation are those of US-DPC coil, which at first exhibited instability and so-called ramp rate limitation (RRL) because of current imbalance in the conductor consisting of chrome-plated strands. Thus the conductance along strands and the inductance of unit length loop and length of the conductor are mostly assumed to be 10 kS/m, 0.5 μH/m and 150 m, respectively. The analysis results indicate that the induced circulation current can be classified into the boundary and interstrand-induce circulation currents hereafter referred to as BICC an IICC. BICC is induced only across the joint at the ends of the conductor, resulting in a constant along the conductor axis, when the total leakage magnetic flux of the loop is not zero. Its decay time constant is quite long, more than a few hours. In contrast, when the leakage magnetic flux distributes along the conductor axis, IICC is induced among strands in the conductor to eliminate this flux. Since the leakage magnetic flux normally becomes largest where the magnetic field is highest, it becomes larger where the time variation of the magnetic field is larger. Its decay time contrast is much less than that of BICC. If the leakage magnetic flux linearly changes along the US-DPC conductor, it is evaluated to be about 10 s. This IICC therefore becomes dominate in a pulse charge, whose ramping tine is less than 10 s. Moreover, it is found that the variation of the leakage a magnetic flux with the relatively long cycle, such as more than a few 10-meter lengths, causes IICC with a decay-time constant of more than several hundred milliseconds. Such and IICC can

    The incidence of pneumothorax is 7 times higher after lung radiofrequency ablation (RFA) than after lung biopsy. The reasons for such a difference have never been objectified. The histopathologic changes in lung tissue are well-studied and established for RF in the ablation zone. However, it has not been previously described what the nature of thermal injury might be along the shaft of the RF electrode as it traverses through normal lung tissue to reach the ablation zone. The purpose of this study was to determine the changes occurring around the RF needle along the pathway between the ablated zone and the pleura. In 3 anaesthetised and ventilated swine, 6 RFA procedures (right and left lungs) were performed using a 14-gauge unipolar multi-tined retractable 3 cm radiofrequency LeVeen probe with a coaxial introducer positioned under CT fluoroscopic guidance. In compliance with literature guidelines, we implemented a gradually increasing thermo-ablation protocol using a RF generator. Helical CT images were acquired pre- and post-RFA procedure to detect and evaluate pneumothorax. Four percutaneous 19-gauge lung biopsies were also performed on the fourth swine under CT guidance. Swine were sacrificed for lung ex vivo examinations, scanning electron microscopy (SEM) and pathological analysis. Three severe (over 50 ml) pneumothorax were detected after RFA. In each one of them, pathological examination revealed a fistulous tract between ablation zone and pleura. No fistulous tract was observed after biopsies. In the 3 cases of severe pneumothorax, the tract was wide open and clearly visible on post procedure CT images and SEM examinations. The RFA tract differed from the needle biopsy tract. The histological changes that are usually found in the ablated zone were observed in the RFA tract's wall and were related to thermal lesions. These modifications caused the creation of a coagulated pulmonary parenchyma rim between the thermo-ablation zone and the pleural space

    Full Text Available This paper serves as an introduction to the special issue of Portal on exile and its potential to effect social change. The critical and creative discussions that follow this introduction respond to a particular set of problems. What factors permit and preclude exilic individual and communal transformation? Is there a need to rethink exilic agency in accord with local times, cultures and places, and to refocus attention on exile communal impacts on a host society? And, in a globalized epoch characterized by mass population movements across geopolitical lines, do states and national desires still have key roles to play in the production of exile? There are no straightforward answers to these questions, but all gesture toward the inadequacy of a single overarching definition or description of exile. Indeed, the process of exile has generated a great deal of debate regarding to whom the term exile applies and when. Furthermore, a number of unresolved issues recur in the extensive literature on the topic: the problematic location of exile and its definitional dependency on a home or homeland; the multivalent struggles to attain and maintain exilic voice, representation, memory, and identity on many fronts (individual, familial, communal, national, transnational; exile’s uneasy relation to modernity, the state, and globalization; and exile’s conceptual competition with other terms, such as diaspora, exodus, refugee and migrant. Intended as a selective reprise of these issues and the ways the contributors to this issue have responded to them, this introduction identifies some of the claims that have been made of exile as a space or mode of social transformation, as well as the possible limits of such claims.

    This paper refers to the synthesis, purification and characterization of [3,5-T] p-aminobenzoic acid (PAB,H' vitamine). The p-aminobenzoic acid is used in the treatment of rheumatic arthritis and dermatological affections. The advantage of tritium labelling of p-aminobenzoic acid is that some biomedical important aspects of collagen's behaviour are made clear. The PAB stimulate the grow of intestinal bacteria so necessary to synthesis of some vitamins (bio tine, pantothenic acid). Tritium is the only radioactive isotope of hydrogen. Several steps have to be carried out in the synthesis of the final product as well as to study its biological behavior. For the labelling of PAB one prefers the substitution of bromine from PAB-3,5-Br with tritium because of simplicity of reaction and the easy synthesis of halogen compound. The first step in synthesis is the protection of NH 2 group through acetylation of PAB. After that PAB is bromated into the 3 and 5 position with elementary bromine. The raw compound is purified and recrystallized and characterized through thin layer chromatography.The tritium labelling is performed through substitution of bromine from bromate derivative, using Pd/C (10% Pd) as catalyst and low basic conditions for the neutralization of HBr resulting from reaction. After the separation of PAB-3,5-T through filtration, the catalyst remains on the filter paper and the labelled compound goes in aqueous solution. PAB-3,5-T is purified through thin layer chromatography with the solvent system n-BuOH:NH 4 OH(25%):H 2 O:EtOH (8:1:2:2,5, v/v) with silica gel GF 254 as support. The determination of activity is carried out with LSC (Liquid Scintillation Counter). A 98% purity was determined through TLC in the same conditions while determination of activity distribution was performed with a 2π Berthold scanner with gas running and without window. The chemical concentration has been measured through UV spectrophotometry and by comparing extinction with

    The first chapter contains a review of the classical theory of elasticity, the theory of thermodynamics, the theory of uncoupled thermoelasticity, the coupled theory of thermoelasticity, the generalized theory of thermoelasticity with one relaxation time, electromagneto thermoelasticity and an introduction to wave propagation in elastic media. Chapter two is devoted to the study of wave propagation for a problem of an infinitely long solid conducting circular cylinder whose lateral surface is traction free and subjected to a known surrounding temperatures in the presence of a uniform magnetic field in the direction of the axis of the cylinder. Laplace transform techniques are used to derive the solution in the Laplace transform domain. The inversion process is carried out using asymptotic expansions valid for short tines. Numerical results are computed for the temperature, displacement, stress,induced magnetic field and induced electric field distributions. The chapter contains also a study of the wave propagation in the elastic medium. In chapter three, we consider the two-dimensional problem of an infinitely long conducting solid cylinder. The lateral surface of the cylinder is taken to be traction free and is subjected to a known temperature distribution independent of z in the presence of a uniform magnetic field in the direction of the axis of the cylinder. Laplace transform techniques are used. The inversion process is carried out using a numerical method based on Fourier series expansions. Numerical results are computed and represented graphically. The chapter contains also a study of the wave propagation in the elastic medium. In chapter four, we consider a two-dimensional problem for an infinity long cylinder. The lateral surface of the cylinder is taken to be traction free and is subjected to a known temperature distribution independent of φ in the presence of a uniform electric field in the direction of the binomial of the cylinder axis.

Conventional methods, including radiopaque markers, scintigraphy, and PillCam™ involve radiation or require the child to swallow a large pill. The minimally invasive, radiation-free Motility Tracking System-1 (MTS-1 has been introduced for description of gastrointestinal motility in adults. The aim of the study was to evaluate the MTS-1 for assessment of gastrointestinal transit times and motility patterns in healthy children. Methods: Twenty-one healthy children (nine girls, median age 10 (range 7–12 years were included. For evaluation with MTS-1, a small magnetic pill was ingested and tracked through the gastrointestinal tract by a matrix of 16 magnetic sensors placed behind a nonmagnetic bed. The children were investigated for 8 hours after swallowing the magnetic pill and again for 4 hours the following morning. After leaving the unit, each child came back after every bowel movement to determine if the pill had been expelled. Results: Nineteen children could swallow the pill. Characteristic contraction patterns were identified for the stomach (three per minute, small intestine (9–11 per minute, and colon (4–5 per minute. Median total gastrointestinal transit time was 37.7 (range 9.5–95.8 hours, median gastric emptying time was 37 (range 2–142 minutes, median small intestinal transit time was 302 (range 164 to >454 minutes, and median colorectal transit time was 38.1 (range 5.6–90.0 hours.

    Shock acceleration is a ubiquitous phenomenon in astrophysical plasmas. Plasma waves and their associated instabilities (e.g., Buneman, Weibel, and other two-stream instabilities) created in collisionless shocks are responsible for particle (electron, positron, and ion) acceleration. Using a three-dimensional relativistic electromagnetic particle (REMP) code, we have investigated particle acceleration associated with a relativistic electron-positron jet front propagating into an ambient electron-positron plasma with and without initial magnetic fields. We find small differences in the results for no ambient and modest ambient magnetic fields. New simulations show that the Weibel instability created in the collisionless shock front accelerates jet and ambient particles both perpendicular and parallel to the jet propagation direction. Furthermore, the nonlinear fluctuation amplitudes of densities, currents, and electric and magnetic fields in the electron-positron shock are larger than those found in the electron-ion shock studied in a previous paper at a comparable simulation time. This comes from the fact that both electrons and positrons contribute to generation of the Weibel instability. In addition, we have performed simulations with different electron skin depths. We find that growth times scale inversely with the plasma frequency, and the sizes of structures created by tine Weibel instability scale proportionally to the electron skin depth. This is the expected result and indicates that the simulations have sufficient grid resolution. While some Fermi acceleration may occur at the jet front, the majority of electron and positron acceleration takes place behind the jet front and cannot be characterized as Fermi acceleration. The simulation results show that the Weibel instability is responsible for generating and amplifying nonuniform, small-scale magnetic fields, which contribute to the electron s (positron s) transverse deflection behind the jet head.

    This article investigates the role of the Saharan air layer (SAL) in tropical cyclogenetic processes associated with a nondeveloping and a developing African easterly wave observed during the Special Observation Period (SOP-3) phase of the 2006 NASA African. Monsoon Multidisciplinary Analyses (NAMMA). The two waves are chosen because they both interact heavily with Saharan air. A glottal data assimilation and forecast system, the NASA Goddard Earth Observing System. version 5 (GEOS-5), is being run to produce a set of high-9 uality global analyses, inclusive of all observations used operationally but with additional satellite information. In particular, following previous works by the same authors, the duality-controlled data from the Atmospheric Infrared Sounder (AIRS) used to produce these analyses have a better coverage than the one adopted by operational centers. From these improved analyses, two sets of 31 five-day high-resolution forecasts, at horizontal resolutions of both half and quarter degrees, are produced. Results indicate that very steep moisture gradients are associated with the SAL in forecasts and analyses, even at great distances from their source over the Sahara. In addition, a thermal dipole in the vertiieat (warm above, cool below) is present in the nondeveloping case. The Moderate Resolution Imaging Spoctroradiometer (MODIS) aboard NASA's Terra and Aqua satellites shows that aerosol optical thickness, indicative of more dust as opposed to other factors, is higher in the nondeveloping case. Altogether, results suggest that the radiative effect of dust may play some role in producing a thermal structure less favorable to cyclogenesis. Results also indicate that only global horizontal resolutions on the order of 20-30 km can capture the large-scale transport and the tine thermal structure of the SAL, inclusive of the sharp moisture gradients, reproducing the effect of tropical cyclone suppression that has been hypothesized by previous authors

The purpose of this study was to explore selected soft drinks (Coca-Cola Classic (registered) , Diet Coke (registered) , Coke Zero (registered) ) as indicators of bioaccessible uranium and other trace elements (As, Ce, Cu, La, Mn, Ni, Pb, Th, Y, Zn) in contaminated soils of the Mary Kathleen uranium mine site, Australia. Data of single extraction tests using Coca-Cola Classic (registered) , Diet Coke (registered) and Coke Zero (registered) demonstrate that extractable arsenic, copper, lanthanum, manganese, nickel, yttrium and zinc concentrations correlate significantly with DTPA- and CaCl 2 -extractable metals. Moreover, the correlation between DTPA-extractable uranium and that extracted using Coca-Cola Classic (registered) is close to unity (+ 0.98), with reduced correlations for Diet Coke (registered) (+ 0.66) and Coke Zero (registered) (+ 0.55). Also, Coca-Cola Classic (registered) extracts uranium concentrations near identical to DTPA, whereas distinctly higher uranium fractions were extracted using Diet Coke (registered) and Coke Zero (registered) . Results of this study demonstrate that the use of Coca-Cola Classic (registered) in single extraction tests provided an excellent indication of bioaccessible uranium in the analysed soils and of uranium uptake into leaves and stems of the Sodom apple (Calotropis procera). Moreover, the unconventional reagent is superior in terms of availability, costs, preparation and disposal compared to traditional chemicals. Contaminated site assessments and rehabilitation of uranium mine sites require a solid understanding of the chemical speciation of environmentally significant elements for estimating their translocation in soils and plant uptake.

Survey respondents with unresolved symptoms or other CAP-related health problems completed a second survey 30 days later; a third survey was completed another 30 days later by respondents with unresolved symptoms or problems. Nationally representative results describing the average time to recovery of symptoms and other CAP-related problems were achieved using post-stratification weights.Results: Five hundred participants completed the initial survey. The time to resolution for the CAP symptoms of weakness, shortness of breath, and tiredness exceeded 3 weeks on average. There was an average of 13 days of absenteeism, and 3 weeks (mean =21 days before achieving full work/activity productivity after CAP. For participants with health conditions that worsened from pneumonia, chronic emphysema and chronic obstructive pulmonary disease took the longest to return to baseline (mean =60 and 52.4 days, respectively.Conclusion: The results from this study demonstrate that older adults surviving a CAP episode experience a significant multi-symptom illness with long recovery periods to achieve pre-CAP health and productivity. These findings highlight the need for further research on effective clinician–patient communication, the need for patient-centered outcomes in clinical trials for CAP therapeutics, adequate home care during

Construct validity was determined through correlation of PETS scores with established measures (measures of chronic condition distress, medication satisfaction, self-efficacy, and global well-being, and known-groups validity through comparisons of PETS scores across clinically distinct groups. In an exploratory test of predictive validity, step-wise regressions were used to determine which PETS scales were most associated with outcomes of chronic condition

This practice gap implies that students enter their professions without valuing interprofessional collaboration and the impact it has on promoting positive patient outcomes.Aim: The aim of this study was to describe the interprofessional experiences of students in health care professional programs as they collaborated to provide health care to Guatemalan citizens over a 7-day period.Methods: In light of the identified practice gap and a commitment by college administration to fund interprofessional initiatives, faculty educators from nursing, occupational therapy, and physical therapy conducted a qualitative study to explore a service-learning initiative focused on promoting interprofessional collaboration. Students collaborated in triads (one student from each of the three disciplines to provide supervised health care to underserved Guatemalan men, women, children, and infants across a variety of community and health care settings. Eighteen students participated in a qualitative research project by describing their experience of interprofessional collaboration in a service-learning environment. Twice before arriving in Guatemala, and on three occasions during the trip, participants reflected on their experiences and provided narrative responses to open-ended questions. Qualitative content analysis methodology was used to describe their experiences of interprofessional collaboration.Results: An interprofessional service

    Most working parents face a common dilemma--how to care for their children when they are not in school but the parents are at work. In this article Kathleen Christensen, Barbara Schneider, and Donnell Butler describe the predictable and unpredictable scheduling demands school-age children place on working couples and single working parents. The authors assess the potential capacity of schools to help meet the needs of working families through changes in school schedules and after-school programs and conclude that the flexibility parents need to balance family-work responsibilities probably cannot be found in the school setting. They argue that workplaces are better able than schools to offer the flexibility that working parents need to attend to basic needs of their children, as well as to engage in activities that enhance their children's academic performance and emotional and social well-being. Two types of flexible work practices seem especially well suited to parents who work: flextime arrangements that allow parents to coordinate their work schedules with their children's school schedules, and policies that allow workers to take short periods of time off--a few hours or a day or two-to attend a parent-teacher conference, for example, or care for a child who has suddenly fallen ill. Many companies that have instituted such policies have benefited through employees' greater job satisfaction and employee retention. Yet despite these measured benefits to employers, workplaces often fall short of being family friendly. Many employers do not offer such policies or offer them only to employees at certain levels or in certain types of jobs. Flexible work practices are almost nonexistent for low-income workers, who are least able to afford alternative child care and may need flexibility the most. Moreover the authors find that even employees in firms with flexible practices such as telecommuting may be reluctant to take advantage of them, because the workplace culture

    The relationship between fertility and income has been a preoccupation of demography since Malthus published the Principles of Population. Of the various approaches surveyed in this article, the economic analysis of fertility pioneered by Gary Becker based on neoclassical consumption theory argues the most strongly for a positive influence of income on fertility. Becker's model views children as consumer goods competing with alternative goods as parents attempt to maximize their utility or satisfaction. The indifference curves, budget lines and other analytical apparatus of microeconomic research are central to this approach. Blake and other opponents have questioned the appropriateness of microeconomic analysis in understanding family size and fertility. The theory of the demographic transition, unlike Becker's approach, views the income-fertility relationship as fundamentally negative. Although there is general consensus that the theory of demographic transition is a cornerstone of demography, there is less agreement as to its actual status. It appears to be less a truly developed theory based on a refined conceptual framework than a description or typology of apparent regularities observed in the past. Various authors have criticized specific elements of economic analysis of fertility. Okun rejected explanations of family size based on orthodox consumption theory because the costs of children, unlike the costs of consumer goods, are not the same for all households, while Mincer added analysis of opportunity costs, in this case referring essentially to the value of the time spent by mothers in child rearing instead of other activities. Several other analysts have suggested modification to the microeconomic approach. 2 recent reflections have contributed to an empirical and theortical synthesis of earlier work incorporating elements of demographic transition theory. Eva Mueller and Kathleen Short, in a work with considerable relevance to the Third World, have

    Reports an error in "Assault-related shame mediates the association between negative social reactions to disclosure of sexual assault and psychological distress" by Christopher R. DeCou, Trevor T. Cole, Shannon M. Lynch, Maria M. Wong and Kathleen C. Matthews ( Psychological Trauma: Theory, Research, Practice, and Policy , 2017[Mar], Vol 9[2], 166-172). In the article, there was an error in the coding of missing values thus effecting the abstract, Methods, Results, and Discussion sections. The frequency counts for sexual assault victimization, reactions to social disclosure, and assault-related shame were calculated incorrectly due to an error in the coding of missing values, and have been corrected in the description of participants and in the results and discussion sections. In addition, the sample size was incorrectly reported as N = 207, and should have appeared as "N = 208." The sample size and corresponding percentages have been corrected throughout the text. Two transcription errors for the indirect effects via PTSD and global distress were also corrected. These indirect effects were incorrectly reported as "PCL-C; β = .27," and "OQ-45.2;β = .21," and should have appeared as "PCL-C;β = .26," and "OQ-45.2; β = .20." (The following abstract of the original article appeared in record 2016-43136-001.) Objective: Several studies have identified associations between social reactions to disclosure of sexual assault and psychological distress; however, no studies have evaluated shame as a mediator of this association. This study evaluated assault-related shame as a mediator of the associations between negative social reactions to disclosure of sexual assault and symptoms of posttraumatic stress disorder (PTSD), depression, and global distress and hypothesized that there would be an indirect effect of social reactions to disclosure upon symptoms of psychopathology via assault-related shame. Participants were 207 female psychology undergraduates who reported past

Because efforts directed toward oral health promotion and disease prevention are fundamentally superior to dental rehabilitation secondary to disease development, early preventive dental visits (EPDVs are widely advocated by professional and academic stakeholders. The aim of this comprehensive review was to critically review and summarize available evidence regarding the effectiveness of EPDVs in improving children's oral health outcomes. Materials and methods: A systematic literature search of the PubMed and Embase electronic databases was undertaken to identify peer-reviewed publications investigating the effectiveness of EPDVs on oral health outcomes, including clinical, behavioral, and cost end points up to October 30, 2013. Outcomes of the identified studies were abstracted and summarized independently by two investigators. Results: Four manuscripts met the inclusion criteria and were included in the review. All studies were conducted in the US and employed a retrospective cohort study design using public insurance-claims data, whereas one study matched claims files with kindergarten state dental surveillance data. That study found no benefit of EPDVs in future clinically determined dental caries levels in kindergarten. The other three studies found mixed support for an association of EPDVs with subsequent more preventive and fewer nonpreventive visits and lower nonpreventive service-related expenditures.

Methods: This single-visit, outpatient study was conducted in 200 patients aged 40 years and older with COPD. All patients underwent spirometry and FeNO testing. COPD severity was classified according to the Global initiative for chronic Obstructive Lung Disease (GOLD 2010 guidelines. Results: Patients who participated in the study had a mean age of 63.9±11.3 years and a mean smoking history of 46±29 pack years. Patients had a mean forced expiratory volume in 1 second % predicted of 53.9%±22.1%. The percentage of patients classified with COPD severity Stage I, II, III, and IV was 13%, 40%, 39%, and 8%, respectively. In addition, according to current procedural terminology codes, 32% of patients were classified as mixed COPD/asthma, 26% as COPD/emphysema, and 42% as all other codes. The mean FeNO level for all patients was 15.3±17.2 parts per billion (ppb. Overall, 89% of patients had a FeNO <25 ppb, 8% had a FeNO 25–50 ppb, and 3% had a FeNO >50 ppb. The percentages of patients with FeNO in the intermediate or high ranges of FeNO were greatest among patients with mixed COPD/asthma (intermediate, 11.5%; high, 6.6% compared with COPD/emphysema (intermediate, 8%; high, 0 and all other codes (intermediate, 6.3%; high, 1.3%. Conclusion: Increases in FeNO were identified in a subset of patients with COPD, particularly in those previously diagnosed with both COPD and asthma. Since FeNO is useful for identifying patients with airway inflammation who will have a beneficial response to treatment with an inhaled corticosteroid, these data may have important

This study investigated the effects of aerobic training on the contribution of nitric oxide (NO, prostaglandins (PG, and endothelial-derived ­hyperpolarizing factor (EDHF in stimulated dorsal foot skin perfusion in individuals with type 2 diabetes (T2DM. Ten previously sedentary, older individuals with T2DM (57.0 ± 3.1 years and nine sedentary controls (53.5 ± 3.2 years were tested before and after undertaking six months of moderate a­erobic training three times weekly in a supervised setting. All subjects underwent measurement of ­baseline (32°C and heat-stimulated (40°C and 44°C dorsal foot skin perfusion starting one hour after ­ingestion of a single, oral 325 mg dose of aspirin, a known inhibitor of PG synthesis. Before aspirin ­ingestion, a subcutaneous microdialysis probe was inserted into each foot dorsum to administer either saline (PG pathway only blocked by aspirin in the left foot or L-NAME (N(G-nitro-l-arginine methyl ester; thereby inhibiting both PG and NO pathways in the right foot. Normative data collected previously on subjects undergoing saline administration via ­microdialysis without aspirin ingestion served as a control group. Significantly lower responsiveness of maximal perfusion was found with the EDHF pathway alone unblocked compared with NO and EDHF unblocked after training. Maximal suppression attributable directly to NO, PG, and EDHF was not significantly different when examined by subject group and training status. However, ­contributions of NO, PG, and EDHF to maximal perfusion were significantly increased, decreased, and unchanged by aerobic training

Researchers at the National Institutes of Health have developed the healing experiences in all life stressors (HEALS questionnaire, an assessment to determine psychosocial spiritual adjustment to healing. Many measures assess religious and spiritual behavior, but there exists a need to capture the meaning of these factors in the process of healing. The instrument consists of spirituality, religion, interpersonal, and intrapersonal domains. This study explores the preliminary partial validation of the spirituality and religion domains of the HEALS against the Ironson–Woods Spirituality and Religiousness Index (IWSR.Methods: The abbreviated HEALS, IWSR, and a measure of depression were completed by 205 human immunodeficiency virus (HIV-infected and HIV-uninfected women from Chicago as part of the Women’s Interagency HIV Study. Total scores on the HEALS and IWSR were correlated using Pearson correlations to examine convergent validity. Total depression scores were analyzed with Pearson correlations to investigate criterion validity.Results: Responses between the abbreviated HEALS and IWSR were highly correlated (r=0.74. Similar to other measures of its kind, scores on the HEALS were associated with depressive symptoms. Women with clinically significant depressive symptoms scored significantly lower on the HEALS than women without. No significant differences were found for

The polymer conjugate (CDP-MP self-assembled into nanoparticles with a size of 27 nm. Release kinetics of MP from the polymer conjugate showed a half-life (t1/2 of 50 h in phosphate buffer solution (PBS and 19 h in human plasma. In vitro, the proliferation of human lymphocytes was suppressed to a similar extent but with a delayed effect when CDP-MP was compared with free MP. In vivo, CDP-MP was administered intravenously to mice with collagen-induced arthritis and compared with free MP. CDP-MP was administered weekly for six weeks (0.07, 0.7, and 7 mg/kg/week and MP was administered daily for six weeks (0.01, 0.1, and 1 mg/kg/day. Body weight changes were minimal in all animals. After 28 days, a significant decrease in arthritis score was observed in animals treated weekly with an intermediate or high dose of CDP-MP. Additionally, dorsoplantar swelling was reduced to baseline in animals treated with CDP-MP at the intermediate and high dose level. Histological evaluation showed a reduction in synovitis, pannus formation and disruption of architecture at the highest dose level of CDP-MP. MP administered daily at equivalent cumulative doses showed minimal efficacy in this model. This study demonstrates that conjugation of MP to a cyclodextrin-polymer may improve its efficacy, leading to lower doses and less frequent administration for a safer and more convenient management of rheumatoid arthritis.Keywords: α-methylprednisolone (MP, cyclodextrin polymer (CDP, polymer conjugate (CDP-MP, rheumatoid arthritis (RA, enhanced permeability and retention effect (EPR

We hypothesized that ranolazine would reduce anginal symptoms or dyspnea in optimally treated ICM patients.Methods: In this randomized, double-blind, crossover-design pilot study, 28 patients with ICM (ejection fraction less or equal 40% were included after providing informed consent. A total of 24 patients completed both placebo and ranolazine treatments and were analyzed. All patients were on treatment with a beta blocker, an angiotensin-converting enzyme inhibitor (or angiotensin receptor blocker, and at least one additional antianginal drug. After randomization, patients received up to 1,000 mg ranolazine orally twice a day, as tolerated, versus placebo. The primary end point was change in angina as assessed by the Seattle Angina Questionnaire (SAQ, or in dyspnea as assessed by the Rose Dyspnea Scale (RDS. Change in the RDS and SAQ score from baseline was compared, for ranolazine and placebo, using the Wilcoxon signed rank test or paired t-test.Results: Patients had the following demographic and clinical variables: mean age of 71.5 years; male (82.1%; prior coronary bypass surgery (67.9%; prior coronary percutaneous intervention (85.7%; prior myocardial infarction (82.1%; diabetes (67.9%; and mean ejection fraction of 33.1%.

There are a number of patient-reported measures that assess burden of treatment in single diseases or in specific treatment contexts. A review of such measures could help identify content for a general measure of treatment burden that could be used with patients dealing with multiple chronic conditions. We reviewed the content and psychometric properties of patient-reported measures that assess aspects of treatment burden in three chronic diseases, ie, diabetes, chronic kidney disease, and heart failure. Methods: We searched Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, and EBSCO CINAHL through November 2011. Abstracts were independently reviewed by two people, with disagreements adjudicated by a third person. Retrieved articles were reviewed to confirm relevance, with patient-reported measures scrutinized to determine consistency with the definition of burden of treatment. Descriptive information and psychometric properties were extracted. Results: A total of 5686 abstracts were identified from the database searches. After abstract review, 359 full-text articles were retrieved, of which 76 met our inclusion criteria. An additional 22 articles were identified from the references of included articles. From the 98 studies, 57 patient-reported measures of treatment burden (full measures or components within measures were identified. Most were multi-item scales

Hysterectomy, the most common surgical treatment of AUB, has significant morbidity, low mortality, long recovery, and high associated health care costs. Global endometrial ablation (GEA provides a surgical alternative with reduced morbidity, cost, and recovery time. The NovaSure® system utilizes unique radiofrequency impedance-based GEA technology. This study evaluated cost effectiveness of AUB treatment with NovaSure ablation versus other GEA modalities and versus hysterectomy from the US commercial and Medicaid payer perspectives. Methods: A health state transition (semi-Markov model was developed using epidemiologic, clinical, and economic data from commercial and Medicaid claims database analyses, supplemented by published literature. Three hypothetical cohorts of women receiving AUB interventions were simulated over 1-, 3-, and 5-year horizons to evaluate clinical and economic outcomes for NovaSure, other GEA modalities, and hysterectomy. Results: Model analyses show lower costs for NovaSure-treated patients than for those treated with other GEA modalities or hysterectomy over all time frames under commercial payer and Medicaid perspectives. By Year 3, cost savings versus other GEA were $930 (commercial and $3,000 (Medicaid; cost savings versus hysterectomy were $6,500 (commercial and $8,900 (Medicaid. Coinciding with a 43%–71% reduction in need for re-ablation, there were 69%–88% fewer intervention/reintervention complications for NovaSure-treated patients versus other GEA modalities
