There is little published about lactation accommodations in public spaces. The objective of this study was to determine what lactation facilities, if any, convention centers in the United States are providing to accommodate breastfeeding moms. A list of national convention centers was collected from meetings-conventions.com and recorded in an Excel spreadsheet, with the name of the center, total meeting square feet, number of meeting rooms, address, and telephone number. Each convention center was contacted by phone and administered the survey. Questions were asked as to what type of lactation accommodations were available, if any. A response rate of 78.7% (326 of 414 convention centers) was achieved. A mere 5.5% reported permanently designated lactation rooms, whereas 32% made temporary accommodations. While the phone survey was conducted, a wide variety of qualitative responses were provided by participants, demonstrating an overall lack of awareness of this as a public health issue. Return to work and breastfeeding in public are commonly reported barriers to breastfeeding. This survey clearly demonstrates a lack of accommodations in very public areas that are visited by women on a regular basis. Policy changes are necessary so all women can be supported in reaching their personal breastfeeding goals.
PROCEEDINGS OF THE 2003 NATIONAL OILHEAT RESEARCH ALLIANCE TECHNOLOGY SYMPOSIUM, HELD AT THE 2003 NEW ENGLAND FUEL INSTITUTE CONVENTION AND 30TH NORTH AMERICAN HEATING AND ENERGY EXPOSITION, HYNES CONVENTION CENTER, PRUDENTIAL CENTER, BOSTON, MASSACHUSETTS, JUNE 9 - 10, 2003.
This meeting is the sixteenth oilheat industry technology meeting held since 1984 and the third since the National Oilheat Research Alliance (NORA) was formed. This year's symposium is a very important part of the effort in technology transfer, which is supported by the Oilheat Research Fuel Flexibility Program under the United States Department of Energy, Distributed Energy and Electricity Reliability Program (DEER). The foremost reason for the conference is to provide a platform for the exchange of information and perspectives among international researchers, engineers, manufacturers, service technicians, and marketers of oil-fired space-conditioning equipment. The conference provides a conduit by which information and ideas can be exchanged to examine present technologies, as well as helping to develop the future course for oil heating advancement. These conferences also serve as a stage for unifying government representatives, researchers, fuel oil marketers, and other members of the oil-heat industry in addressing technology advancements in this important energy use sector. The specific objectives of the conference are to: (1) Identify and evaluate the current state-of-the-art and recommend new initiatives for higher efficiency, a cleaner environment, and to satisfy consumer needs cost effectively, reliably, and safely; (2) Foster cooperative interactions among federal and industrial representatives for the common goal of sustained economic growth and energy security via energy conservation.
As a world first, 300 m² of dye-sensitized solar cells will be integrated into the facade of the EPFL's Convention Center. This prototype will constitute the first application of such technology to a public building. The translucent panels are constructed and assembled by local small and medium businesses and make use of an invention by EPFL researcher Michael Grätzel. This project is embedded within the framework of the partnership established in 2009 between EPFL and Romande Energie - whose aim is to create one of the largest solar energy parks in Switzerland.

Full Text Available Objective: The objective of this study was to evaluate the results of Anderson-Hynes pyeloplasty with isthmotomy and lateropexy in horseshoe kidney with pelviureteric junction obstruction (PUJO. Materials and Methods: Medical records of patients of horseshoe kidney with PUJO operated in our institute between June 1998 and June 2012 were reviewed. Anderson-Hynes pyeloplasty with isthmotomy and lateropexy was performed in all patients. The surgical outcome was evaluated with emphasis on the changes in degree of hydronephrosis by ultrasonography, renal drainage and function assessed by diuretic renal scans. Results: We studied the records of eight children of horseshoe kidney having unilateral PUJO. Obstruction was caused by a crossing lower-pole vessel in two cases, a high ureteral insertion in three and narrowing of the PUJ in three cases. Post-operative follow-up (median 4.4 years, range 18 months to 10 years revealed improved renal function and good drainage in all cases. Hydronephrosis disappeared in 3, 4 showed Grade 1 and one showed Grade 2 hydronephrosis. All children are doing well and have no symptoms. Conclusion: Anderson-Hynes pyeloplasty with isthmotomy and lateropexy is a highly effective and safe procedure for treating PUJO in horseshoe kidney in children.

Full Text Available In Italy, the use of non conventional medicines (NCMs is spreading among people as in the rest of Europe. Sales of alternative remedies are growing, and likewise the number of medical doctors (MDs who practise NCM/complementary and alternative medicine (CAM. However, in Italy as in other countries of the European Union, at the present time the juridical/legal status of NCM/CAM is not well established, mainly due to the lack of any national law regulating NCM/CAM professional training, practice and public supply and the absence of government-promoted scientific research in this field. This is an obstacle to safeguarding the patient's interests and freedom of choice, especially now that dissatisfaction with biomedicine is inclining more and more people to look for a holistic and patient-centered form of medicine.

Pneumococci are common colonizer, especially of children, and cocolonization of different serotypes is an important factor for intraspecies genetic exchange. The aim of this study was to analyze pneumococcal carriage and serotype distribution in unvaccinated healthy children in Iceland and compare conventional culture methods and molecular methods using DNA extracted directly from the samples. Nasopharyngeal swabs were obtained from 514 children aged 2-6 year attending day care centers in Reykjavik in 2009. The swabs were selectively cultured for pneumococci and the isolates serotyped using latex agglutination. DNA was also extracted directly from the swabs and serotyped using a multiplex PCR panel designed to detect vaccine serotypes and the most commonly carried non-vaccine serotypes. Pneumococcal carriage was detected in 391 (76.1%) of the children using polymerase chain reaction (PCR) and in 371 (72.2%) using conventional methods. Cocolonization was detected in 92 (23.5%) of the carriers when PCR method was used and in 30 (8.1%) when conventional methods were used, detecting 500 and 401 strains, respectively (P < 0.0001). The most common serotypes were 23F, 19A, 6B, 6A and 19F, rates 13-8%. The number of isolates of serotypes included in the 10-valent and 13-valent vaccines and detected by PCR were 234 (58.4%) and 363 (90.5%), respectively and by conventional methods 186 (46.4%) and 293 (73.1%), respectively. Cocolonization was detected in a fourth of the children carrying pneumococci using DNA extracted directly from nasopharyngeal swabs. The rate of carriage was very high, but no serotype dominated, and the children were commonly colonized by vaccine serotypes, especially cocolonized children.

A series of 48 patients with hydronephrosis (mean age 31 yrs.) underwent on Anderson-Hynes pyeloplasty. Assessment was carried out in 30 pts. after a mean observation time of 90 months, with a minimum 5 years follow-up. Clinical examination, laboratory investigations, renal ultrasonography, urography and renal scan were performed pre-operatively and at follow-up. There was one patient with evidence of stenosis in the ureteropelvic junction; one patient developed urinary leakage post-operatively and required surgical correction. All patients had symptoms pre-operatively and no one had symptoms post-operatively. Four patients had calcolosis associated, postoperatively all pts. were stone free; four years later one patient developed litiasis. We observed that the results of surgical intervention in hydronephrosis are excellent especially in patients aged less than 30 years.

The non-native barnacle species Austrominius modestus was first recorded in Ireland, close to Lough Hyne marine nature reserve in 1957. This species was not recorded inside the Lough until 1980, but by 2001 was the dominant intertidal barnacle within the reserve. It has been suggested that increases in the abundance of this species at other locations in Europe may be linked to increasing sea surface temperatures, and that A. modestus is an ;ecological sleeper;. Despite an overall trend for increasing sea surface temperatures, this long term warming is punctuated by extreme events such as severely cold winters. A. modestus is warm water adapted, and has been recorded to decrease in abundance following cold winters. The winters of 2009/2010 and 2010/2011 were amongst the coldest recorded in Ireland in past decades. In the present study, higher levels of mortality were recorded for A. modestus than native barnacle species in Lough Hyne following these cold winters. Additionally, this species was recorded at lower abundances at the majority of sites surveyed in Lough Hyne in 2011 compared with 2009. Despite this, A. modestus remains the dominant barnacle species in the Lough and monitoring the recruitment of intertidal barnacles within Lough Hyne during 2014-2015 revealed that A. modestus was the most abundant recruit at study sites, both in removal plots and in the pre-existing community. The year-round breeding of A. modestus in addition to the closed nature of the Lough promotes A. modestus within the reserve. Despite this, native barnacle species continue to persist in Lough Hyne, though generally at low abundances, with the exception of exposed locations such as the Rapids and Bullock Island where natives outnumber A. modestus. The future intertidal barnacle community within the Lough is likely to be dominated by A. modestus with Chthamalus montagui and C. stellatus being abundant at sites which are not suitable for A. modestus. While the consequences of this are

E-cigarette use is increasing, and the long-term impact on public health is unclear. We described the acute adverse health effects from e-cigarette exposures reported to U.S. poison centers. We compared monthly counts and demographic, exposure, and health effects data of calls about e-cigarettes and conventional cigarettes made to poison centers from September 2010 through December 2014. Monthly e-cigarette calls increased from 1 in September 2010, peaked at 401 in April 2014, and declined to 295 in December 2014. Monthly conventional cigarette calls during the same period ranged from 302 to 514. E-cigarette calls were more likely than conventional cigarette calls to report adverse health effects, including vomiting, eye irritation, and nausea. Five e-cigarette calls reported major health effects, such as respiratory failure, and there were two deaths associated with e-cigarette calls. E-cigarette calls to U.S. poison centers increased over the study period, and were more likely than conventional cigarettes to report adverse health effects. It is important for health care providers and the public to be aware of potential acute health effects from e-cigarettes. Developing strategies to monitor and prevent poisonings from these novel devices is critical.

In the Netherlands, the current standard of care for treating patients with end-stage renal disease is three sessions of in-center hemodialysis (conventional ICHD). However, the literature indicates that high dose hemodialysis (high dose HD) may provide better health outcome such as survival and quality of life. The objective of this study was to determine the cost-effectiveness of high dose HD, both in-center and at home, in comparison to conventional ICHD from a Dutch payer's perspective over a 5 year period. Additionally, the cost-effectiveness of conventional HD at home in comparison to conventional ICHD will be analysed. A Markov model was developed assuming 28-day treatment cycles and was populated with data from Dutch and international renal registries, official tariffs and medical literature. Univariable and probabilistic sensitivity analyses were performed to test the robustness of the results. Using publicly available tariffs from the Dutch Healthcare Authority (Nederlandse Zorgautoriteit) of 2015, doing high dose ICHD instead of conventional ICHD shows an incremental cost-effectiveness ratio (ICER) of €275,747 per quality-adjusted life year (QALY) gained. In contrast, the ICER of high dose HD at home in comparison to conventional ICHD is €3248 per gained QALY. The final analysis shows that conventional HD at home is less costly per patient (-€3063) than conventional ICHD and results in health benefit improvement (+0.249 QALYs), and is therefore regarded as cost saving. Treating dialysis patients with conventional HD at home shows to be cost saving in comparison to conventional ICHD. However, the magnitude of clinical benefit of high dose HD at home is over two times greater than the clinical benefit of conventional HD at home. According to our analysis, from a payer's perspective, high dose HD should be offered as a home therapy to obtain its clinical benefits in a cost-effective manner. Future research should consider our findings alongside

To investigate the cost-effectiveness of high-dose hemodialysis (HD) versus conventional in-center HD (ICHD), over a lifetime time horizon from the UK payer's perspective. We used a Markov modeling approach to compare high-dose HD (in-center or at home) with conventional ICHD using current and hypothetical home HD reimbursement tariffs in England. Sensitivity analyses tested the robustness of the results. The main outcome measure was the incremental cost-effectiveness ratio (ICER) expressed as a cost per quality-adjusted life-year (QALY). Over a lifetime, high-dose HD in-center (5 sessions/wk) is associated with higher per-patient costs and QALYs (increases of £108,713 and 0.862, respectively) versus conventional ICHD. The corresponding ICER (£126,106/QALY) indicates that high-dose HD in-center is not cost-effective versus conventional ICHD at a UK willingness-to-pay threshold of £20,000 to £30,000. High-dose HD at home is associated with lower total costs (£522 less per patient) and a per-patient QALY increase of 1.273 compared with ICHD under the current Payment-by Results reimbursement tariff (£456/wk). At an increased home HD tariff (£575/wk), the ICER for high-dose HD at home versus conventional ICHD is £17,404/QALY. High-dose HD at home had a 62% to 84% probability of being cost-effective at a willingness-to-pay threshold of £20,000 to £30,000/QALY. Although high-dose HD has the potential to offer improved clinical and quality-of-life outcomes over conventional ICHD, under the current UK Payment-by Results reimbursement scheme, it would be considered cost-effective from a UK payer perspective only if conducted at home.

The intensely adversarial relationship between India and Pakistan is marked by military rivalry, mutual distrust, and suspicion. The most dividing disagreement has been over the Kashmir region. An inability to discuss the Kashmir issue has prevented discussion on other important issues. Since there is little prospect of detente, at least in the near-term, the question is whether this rivalry can be contained by other means, such as arms control approaches. Conventional arms control has been applied flexibly and successfully in some regions to reduce threat-perceptions and achieve reassuring military stability. Some lessons from other international models might be applied to the India/Pakistan context. This paper discusses the status of conventional arms control in South Asia, the dominant Indian and Pakistani perceptions about arms control, the benefits that could be derived from arms control, as well as the problems and prospects of arms control. It also discusses existing conventional arms control agreements at the regional and global levels as well as the potential role of cooperative monitoring technology.

Separate meta-analyses of the cognitive ability and assessment center (AC) literatures report higher criterion-related validity for cognitive ability tests in predicting job performance. We instead focus on 17 samples in which both AC and ability scores are obtained for the same examinees and used to predict the same criterion. Thus, we control for differences in job type and in criteria that may have affected prior conclusions. In contrast to Schmidt and Hunter's (1998) meta-analysis, reporting mean validity of .51 for ability and .37 for ACs, we found using random-effects models mean validity of .22 for ability and .44 for ACs using comparable corrections for range restriction and measurement error in the criterion. We posit that 2 factors contribute to the differences in findings: (a) ACs being used on populations already restricted on cognitive ability and (b) the use of less cognitively loaded criteria in AC validation research.

The literature comparing SILS to conventional laparoscopic surgery for treatment of this disease is limited. This study aimed to evaluate the feasibility and effectiveness of SILS compared with conventional laparoscopic resection for GIST.Methods: A retrospective case-cohort study compared the benefits and outcomes of SILS and conventional laparoscopic partial gastrectomy for GIST. Between April 2008 and December 2012, 39 patients underwent laparoscopic gastrectomy for gastric stromal tumors in our department. All operations were performed by a single experienced surgeon. The medical records of these patients were reviewed retrospectively with regard to tumor size, operating time, and other clinical features.Results: SILS resection was performed on 19 patients, whereas 20 patients had conventional laparoscopic resection. Compared with the conventional laparoscopic group, the operative time for the SILS group was shorter, but the time for recovery of gastrointestinal function and postoperative hospital stay for the SILS group was similar to that of the conventional laparoscopic group. No intraoperative or postoperative complications were recorded in either group.Conclusion: Compared with the conventional laparoscopic procedure, SILS in gastric stromal tumors is as feasible and safe when performed by experienced surgeons.Keywords: gastric stromal tumor, SILS

Hand hygiene is the cornerstone of aseptic techniques to reduce surgical site infection. Conventional surgical scrub is effective for disinfecting a surgeon's hands. However, the compliance of conventional scrub may be hindered by skin damage, allergy, and time. Alcohol-based hand rub has a satisfactory antimicrobial effect, but mostly in laboratory settings. Our aim was to compare a conventional surgical scrub with an alcohol-based hand rub to evaluate antimicrobial efficacy. From June 1, 2010 to July 31, 2011, 128 healthcare workers were enrolled in the study. They used an alcohol-based hand rub or a conventional surgical scrub as preoperative hand antisepsis during their routine practice. Hand sampling for cultures were performed before and after operations. Positive culture plates were further processed for pathogen identification. The culture positive rate of the alcohol-based hand rub was 6.2% before operations and 10.8% after operations. Both rates were lower than the conventional surgical scrub [47.6% before operations (p rub was a significant protective factor for positive hand cultures. The alcohol-based hand rub was more efficacious for surgical antisepsis and had sustained efficacy, compared to conventional surgical scrub. We suggest that alcohol-based hand rubs could be an alternative surgical antiseptic in the operative theater. Copyright © 2013. Published by Elsevier B.V.

Sweden has had specialized 'allergen avoidance daycare centers' (AADC) since 1979. The aim was to compare AADC with ordinary daycare centers (ODC). Through contacts with municipalities and hospitals, 72 AADC were identified. For each AADC, the two nearest ODCs served as controls. A questionnaire was sent to the local directors of the 216 daycare centers (531 sections), 83% responded. A total of 39% of the ODCs had ever had dampness/molds, 12% were near (daycare centers differ from other daycare centers, and may have better indoor environments. There is a need to improve the indoor environments of daycare centers, including reduction of building dampness and molds. Allergen avoidance daycare centers (AADC) in Sweden differ from ordinary daycare centers in many respects, with fewer indoor and building factors related to dust, allergens and irritants. This shows that the indoor environments of daycare centers can be improved. Data suggest that AADC may have lower levels of pet allergens, and this is beneficial for children with pet allergy. The effects of these improvements on indoor exposures and health of the children need to be further evaluated.

In countries like Iran, circumcision is done purely on religious grounds. In this study, we outline 390 cases in our practice and describe the epidemiology, indications, surgical technique used, and the early complications.Materials and methods: In this retrospective study, the charts for 390 circumcision cases were analyzed for the period March 2005 to August 2010. We reviewed all cases, noting age, indication, type of anesthesia used, technique, cosmetic appearance, and any potential early complications. All cases were followed up 1–4 weeks postoperatively and their notes were evaluated.Results: The age of children who underwent circumcision ranged from 3 weeks to 14 years, with a mean age of 4.25 years. The most common age for circumcision was 4–5 years (14.6%, and the least common age was 11–12 years (1.5%. In 372 cases (95%, the parents had opted for the procedure for religious reasons, and in 18 cases (5%, there was a medical indication, including phimosis (11 cases, 3%, urinary tract infection (5 cases, 1.2%, and balanoposthitis (2 cases, 0.8%.

The Antibacterial Resistance Leadership Group (ARLG) Laboratory Center (LC) leads the evaluation, development, and implementation of laboratory-based research by providing scientific leadership and supporting standard/specialized laboratory services. The LC has developed a physical biorepository and a virtual biorepository. The physical biorepository contains bacterial isolates from ARLG-funded studies located in a centralized laboratory and they are available to ARLG investigators. The Web-based virtual biorepository strain catalogue includes well-characterized gram-positive and gram-negative bacterial strains published by ARLG investigators. The LC, in collaboration with the ARLG Leadership and Operations Center, developed procedures for review and approval of strain requests, guidance during the selection process, and for shipping strains from the distributing laboratories to the requesting investigators. ARLG strains and scientific and/or technical guidance have been provided to basic research laboratories and diagnostic companies for research and development, facilitating collaboration between diagnostic companies and the ARLG Master Protocol for Evaluating Multiple Infection Diagnostics (MASTERMIND) initiative for evaluation of multiple diagnostic devices from a single patient sampling event. In addition, the LC has completed several laboratory-based studies designed to help evaluate new rapid molecular diagnostics by developing, testing, and applying a MASTERMIND approach using purified bacterial strains. In collaboration with the ARLG's Statistical and Data Management Center (SDMC), the LC has developed novel analytical strategies that integrate microbiologic and genetic data for improved and accurate identification of antimicrobial resistance. These novel approaches will aid in the design of future ARLG studies and help correlate pathogenic markers with clinical outcomes. The LC's accomplishments are the result of a successful collaboration with the ARLG

Accurate intima-media thickness (IMT) measurement of the carotid artery from minimal plaque ultrasound images is a relevant clinical need, since IMT increase is related to the progression of atherosclerosis. In this paper, we describe a novel dual snake-based model for the high-performance carotid IMT measurement, called Carotid Measurement Using Dual Snakes (CMUDS). Snakes (which are deformable contours) adapt to the lumen-intima (LI) and media-adventitia (MA) interfaces, thus enabling the IMT computation as distance between the LI and MA snakes. However, traditional snakes might be unable to maintain a correct distance and in some spatial location along the artery, it might even collapse between them or diverge. The technical improvement of this work is the definition of a dual snake-based constrained system, which prevents the LI and MA snakes from collapsing or bleeding, thus optimizing the IMT estimation. The CMUDS system consists of two parametric models automatically initialized using the far adventitia border which we automatically traced by using a previously developed multi-resolution approach. The dual snakes evolve simultaneously and are constrained by the distances between them, ensuring the regularization of LI/MA topology. We benchmarked our automated CMUDS with the previous conventional semi-automated snake system called Carotid Measurement Using Single Snake (CMUSS). Two independent readers manually traced the LIMA boundaries of a multi-institutional, multi-ethnic, and multi-scanner database of 665 CCA longitudinal 2D images. We evaluated our system performance by comparing it with the gold standard as traced by clinical readers. CMUDS and CMUSS correctly processed 100% of the 665 images. Comparing the performance with respect to the two readers, our automatically measured IMT was on average very close to that of the two readers (IMT measurement biases for CMUSS was equal to -0.011±0.329mm and -0.045±0.317mm, respectively, while for CMUDS, it was

Aim of this study was to investigate the accuracy of a conventional over-the-top-guide (OTG) with a typically short offset to hit the center of the native femoral ACL footprint through the anteromedial portal in comparison to a specific medial-portal-aimer (MPA) with larger offset. In 20 matched human cadaveric knees, insertion sites of the ACL were marked in medial arthrotomy. An OTG with an offset of 5.5 mm, respectively, the MPA with 9 mm offset was used in a medial portal approach to locate the center of a single bundle ACL reconstruction tunnel with k-wires. Distances from the footprint center, the OTG drilling and the MPA drilling to the roof of the intercondylar notch and to the deep cartilage margin were determined. After positioning of radiological markers, radiographic analysis was performed according to the quadrant technique as described by Bernard and Hertel. The distance from ACL origin to the roof of the notch was 10.3 (±2.1) mm, in the OTG group 6.7 (±1.5) mm and in the MPA group 9.6 (±1.9) mm. The distance to the deep cartilage margin was 9.5 (±1.7) mm from ACL origin, 4.8 (±1.3) mm with OTG and 8.7 (±1.4) mm with MPA. There were statistically significant differences between the distances of the footprint center and the OTG group after measuring and also after radiographic analysis (p 0.0001). There was an increased risk for femoral blow (9/10 vs. 0/10) in the OTG group after overdrilling with a 9 mm drill. Short (5.5 mm) offset femoral aiming devices fail to locate the native ACL footprint center in medial portal approach with an increased risk for femoral blowout when overdrilling. The special medial-portal-aiming device with 9 mm offset hit the center reliably.

To determine whether laparo-endoscopic single-site surgery (LESS) results in less postoperative pain and a better cosmetic surgical scar compared with conventional laparoscopy. Prospective randomized controlled trial. A county hospital in Norway. Forty women with benign adnexal disease or a hereditary cancer risk scheduled for laparoscopic adnexal surgery. LESS or conventional laparoscopy. Postoperative pain 24 hours after surgery. There was no difference in pain at 24 hours after surgery, with a mean score of 3.0 (SD 2.1) in the LESS group and 2.5 (SD 1.5) in the conventional laparoscopy group. Significantly more shoulder tip pain was reported by women undergoing LESS compared with those having conventional surgery at 6 and 24 hours after surgery. A high satisfaction with the cosmetic result was reported in both groups, with no significant difference in the Manchester scar scale score. Although similar levels of postoperative pain are experienced by women having LESS and conventional laparoscopic surgery, women having LESS report significantly more shoulder tip pain compared to those having conventional laparoscopic surgery. This may relate to a significantly longer operation time in the LESS group. NCT01288599. Copyright © 2012 American Society for Reproductive Medicine. All rights reserved.

Conclusion: c-TBNA with ROSE is a safe, efficacious, and cost-effective bronchoscopic modality. When it was performed by operators routinely performing EBUS-TBNA, diagnostic yields similar to that of EBUS-TBNA can be obtained. Even at the centers where EBUS facilities are available, c-TBNA should be routinely performed.

In conventional pig husbandry, antibiotics are frequently applied. Together with excreta, antibiotic residues enter liquid manures finally used as organic soil fertilizers or input materials for biogas plants. Therefore, this first screening study was performed to survey the application patterns of antibiotics from fall 2011 until spring 2013. Manures and digestates were then analyzed for selected antibiotic residues from spring 2012 to 2013. The data analysis of veterinary drug application documents revealed the use of 34 different antibiotics belonging to 11 substance classes at 21 farms under study. Antibiotics, particularly tetracyclines, frequently administered to larger pig groups were detected in manure samples up to higher mg kg(-1) dry weight (DW) concentrations. Antibiotic residues in digestates, furthermore, show that a full removal capacity cannot be guaranteed through the anaerobic digestion process in biogas plants. Copyright © 2016 Elsevier Ltd.

The high morbidity and mortality in dialysis warrant further research and insight into the clinical domains of the technique and practice of this therapy. In the last 20 years, the focus of development in the field of hemodialysis (HD has centered around adequate removal of urea and other associated toxins. High-dose HD offers an opportunity to improve mortality, morbidity, and quality of life of patients with end-stage kidney disease. However, the uptake of this modality is low, and the risk associated with the therapy is not fully understood. Recent studies have highlighted the evidence base and improved our understanding of this technique of dialysis. This article provides a review of high-dose and home HD, its clinical impact on patient outcome, and the controversies that exist. Keywords: hemodialysis, home dialysis, high dose, outcomes

The purpose of this in-vitro study was to compare canal transportation and centering ability of Twisted and Hyflex Rotary Files with stainless steel hand k-flexofiles by using Spiral Computed Tomography. A total of 90 freshly extracted human mandibular single rooted Premolar teeth were selected. The crowns were flattened with steel disks and a final dimension of 18-mm WL was achieved for each tooth. Canals were divided randomly into 3 groups of 30 teeth each. Group I:Hyflex files, Group II:Twisted files, Group III:stainless steel hand k-flexofiles. Three sections from apical, mid-root, and coronal levels of the canal were recorded. All the teeth were scanned before and after instrumentation by using Spiral Computed Tomography. K-files showed highest transportation and less centered when compared to the Twisted and Hyflex rotary files. No significant difference was found between TF and Hyflex CM instruments. TF and Hyflex files shaped curved root canals without significant shaping errors when compared to the Hand stainless steel k-flexofiles.

Bergman-type phases in the Na-Au-T (T = Ga, Ge, and Sn) systems were synthesized by solid-state means and structurally characterized by single-crystal X-ray diffraction studies. Two structurally related (1/1) Bergman phases were found in the Na-Au-Ga system: (a) a conventional Bergman-type (CB) structure, Na(26)Au(x)Ga(54-x), which features empty innermost icosahedra, as refined with x = 18.1 (3), Im3, a = 14.512(2) Å, and Z = 2; (b) a stuffed Bergman-type (SB) structure, Na(26)Au(y)Ga(55-y), which contains Ga-centered innermost icosahedra, as refined with y = 36.0 (1), Im3, a = 14.597(2) Å, and Z = 2. Although these two subtypes have considerable phase widths along with respective tie lines at Na ≈ 32.5 and 32.1 atom %, they do not merge into a continuous solid solution. Rather, a quasicrystalline phase close to the Au-poor CB phase and an orthorhombic derivative near the Au-rich SB phase lie between them. In contrast, only Au-rich SB phases exist in the Ge and Sn systems, in which the innermost icosahedra are centered by Au rather than Ge or Sn. These were refined for Na(26)Au(40.93(5))Ge(14.07(5)) (Im3, a = 14.581(2) Å, and Z = 2) and Na(26)Au(39.83(6))Sn(15.17(6)) (Im3, a = 15.009(2) Å, and Z = 2), respectively. Occupations of the centers of Bergman clusters are rare. Such centering and coloring correlate with the sizes of the neighboring icosahedra, the size ratios between electropositive and electronegative components, and the values of the average valence electron count per atom (e/a). Theoretical calculations revealed that all of these phases are Hume-Rothery phases, with evident pseudogaps in the density of states curves that arise from the interactions between Fermi surface and Brillouin zone boundaries corresponding to a strong diffraction intensity.

Located in the South of Minas Gerais, average altitude of 1186 m and population about 170.000 inhabitants Pocos de Caldas is one of the most developed tourist cities of Minas Gerais. Beyond this quality, that makes it one of the best cities in quality of life in Brazil, measured for the HDI, the city presents an enviable educational polar region comparing to cities of the south region. With 91 institutions of education, from children's education to superior education, Pocos de Caldas has more than 49,000 students today. From this scholar population, 1870 pupils represent the children's education in particular or municipal day-care centers, called CEI. Pocos de Caldas has its own generation of energy through the Municipal Department of Electricity, DME. The energy production today arrives the house of 58 MW reaching 100% of the population in 2005. The analysis of the substitution of conventional system of electric heating for solar heating in day-care centers has left of an unknown project, with the objective to minimize the consumption of energy unfastened during the children's baths who stay at CEI. In this context, this work presents a study carried through this project, after the implantation of the related system in four of the eleven day-care centers that the initial project composes. The data had been collected in the DME and the City department of Education. The pathological manifestations in the points of water consumption of the related day-care centers as well as the state of conservation of the systems of implanted solar heating had been investigated also.

Full Text Available The scope of the paper is to review the literature that employs coordination games to study social norms and conventions from the viewpoint of game theory and cognitive psychology. We claim that those two alternative approaches are in fact complementary, as they provide different insights to explain how people converge to a unique system of self-fulfilling expectations in presence of multiple, equally viable, conventions. While game theory explains the emergence of conventions relying on efficiency and risk considerations, the psychological view is more concerned with frame and labeling effects. The interaction between these alternative (and, sometimes, competing effects leads to the result that coordination failures may well occur and, even when coordination takes place, there is no guarantee that the convention eventually established will be the most efficient.
El objetivo de este artículo es presentar la literatura que emplea los juegos de coordinación para el estudio de normas y convenciones sociales, que se han analizado tanto desde el punto de vista de la teoría de juegos como de la psicología cognitiva. Argumentamos en este trabajo que estos dos enfoques alternativos son en realidad complementarios, dado que ambos contribuyen al entendimiento de los procesos mediante los cuales las personas llegan a coordinarse en un único sistema de expectativas autorrealizadas, en presencia de múltiples convenciones todas ellas igualmente viables. Mientras que la teoría de juegos explica la aparición de convenciones basándose en argumentos de eficiencia y comportamientos frente al riesgo, el enfoque de la psicología cognitiva utiliza en mayor medida consideraciones referidas al entorno y naturaleza de las decisiones. La interacción entre estos efectos diferentes (y en ocasiones, rivales desemboca con frecuencia en fallos de coordinación y, aun cuando la coordinación se produce, no hay garantía de que la convención en vigor sea la m

Two theoretical approaches – Conventions and Institutional Logics – are brought together and the similarities and differences between the two are explored. It is not the intention to combine the approaches, but I would like to open both ‘boxes’ and make them available to each other with the purpose...... of creating a space for dialog. Both approaches were developed in the mid-1980s as a reaction to rational-choice economic theory and collectivistic sociological theory. These two theories were oversimplifying social life as being founded either in actor-micro level analyses or in structure-macro level...... by overcoming traditional micro-macro and actor-structure dimensions. However, they have also achieved this in different ways and I ask if there is a benefit to ‘importing’ some of these differences into the other approach....

Full Text Available The provision of mechanical ventilation for the support of infants and children with respiratory failure or insufficiency is one of the most common techniques that are performed in the Pediatric Intensive Care Unit (PICU. Despite its widespread application in the PICUs of the 21st century, before the 1930s, respiratory failure was uniformly fatal due to the lack of equipment and techniques for airway management and ventilatory support. The operating rooms of the 1950s and 1960s provided the arena for the development of the manual skills and the refinement of the equipment needed for airway management, which subsequently led to the more widespread use of endotracheal intubation thereby ushering in the era of positive pressure ventilation. Although there seems to be an ever increasing complexity in the techniques of mechanical ventilation, its successful use in the PICU should be guided by the basic principles of gas exchange and the physiology of respiratory function. With an understanding of these key concepts and the use of basic concepts of mechanical ventilation, this technique can be successfully applied in both the PICU and the operating room. This article reviews the basic physiology of gas exchange, principles of pulmonary physiology, and the concepts of mechanical ventilation to provide an overview of the knowledge required for the provision of conventional mechanical ventilation in various clinical arenas.

For patients who have chondrosarcoma with unresectable disease, because of tumor location, tumor size, or extensive metastatic disease, treatment options are very limited because of their relative resistance to radiotherapy and chemotherapy. The overall survival of this patient population is poor; however, specific studies are lacking, and large series have not been published. Therefore, the authors conducted this retrospective, 2-center study to gain insight into the outcome of patients with advanced, unresectable, conventional central chondrosarcoma. All patients with unresectable conventional central chondrosarcoma who were diagnosed between January 1, 1980 and December 31, 2011 in 2 major European bone sarcoma centers (Rizzoli Institute, Bologna, Italy and Leiden University Medical Center, Leiden, the Netherlands) were selected. Relevant information was collected from the medical records at both centers. In total, 171 patients met the selection criteria. The overall survival rate for all patients was 48% at 1 year, 24% at 2 years, 12% at 3 years, 6% at 4 years, and 2% at 5 years. Patients with unresectable, locally advanced disease without distant metastases had a significantly better survival than patients with metastatic disease (P = .0014). Systemic treatment, consisting of either doxorubicin-based chemotherapy or the noncytotoxic drugs imatinib and sirolimus, improved survival significantly compared with no treatment (P = .0487). For patients who had locally advanced disease without metastases, radiotherapy was associated with a survival benefit (P = .0032). This study provides a standard for overall survival rates after a diagnosis of unresectable conventional central chondrosarcoma. Systemic treatment and radiotherapy may improve survival, although selection bias because of the retrospective nature of this study may have influenced the outcome. The poor survival underlines the need for new therapeutic options for this patient population. Cancer 2014

The global conventional arms trade is worth tens of billions of dollars every year and is engaged in by every country in the world. Yet, it is often difficult to control the legal trade in conventional arms and there is a thriving illicit market, willing to arm unscrupulous regimes and nefarious non-state actors. This chapter examines the international conventional arms trade, the range of tools that have been used to control it, and challenges to these international regimes.

A non-recursive model is proposed and empirically tested with data of opponents of nuclear power. In explaining conventional and unconventional participation the theory of collective action is applied and modified in two respects: the perceived influence on the elimination of collective evils are taken into account; the selective incentives considered are non-material ones. These modifications proved to be valid: the collective good variables and non-material incentives were important determinants for the two forms of participation. Another result was that there is a reciprocal causal relationship between conventional and unconventional participation.

The aim of this study was to report on the development of a standardized target and organ-at-risk naming convention for use in radiation therapy and to present the nomenclature for structure naming for interinstitutional data sharing, clinical trial repositories, integrated multi-institutional collaborative databases, and quality control centers. This taxonomy should also enable improved plan benchmarking between clinical institutions and vendors and facilitation of automated treatment plan quality control. The Advanced Technology Consortium, Washington University in St. Louis, Radiation Therapy Oncology Group, Dutch Radiation Oncology Society, and the Clinical Trials RT QA Harmonization Group collaborated in creating this new naming convention. The International Commission on Radiation Units and Measurements guidelines have been used to create standardized nomenclature for target volumes (clinical target volume, internal target volume, planning target volume, etc.), organs at risk, and planning organ-at-risk volumes in radiation therapy. The nomenclature also includes rules for specifying laterality and margins for various structures. The naming rules distinguish tumor and nodal planning target volumes, with correspondence to their respective tumor/nodal clinical target volumes. It also provides rules for basic structure naming, as well as an option for more detailed names. Names of nonstandard structures used mainly for plan optimization or evaluation (rings, islands of dose avoidance, islands where additional dose is needed [dose painting]) are identified separately. In addition to its use in 16 ongoing Radiation Therapy Oncology Group advanced technology clinical trial protocols and several new European Organization for Research and Treatment of Cancer protocols, a pilot version of this naming convention has been evaluated using patient data sets with varying treatment sites. All structures in these data sets were satisfactorily identified using this

In 1993, as the CWC ratification process was beginning, concerns arose that the complexity of integrating the CWC with national law could cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States as to how the CWC would be carried out. As a result, the author's colleagues and the author prepared the Manual for National Implementation of the Chemical Weapons Convention and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Committee of CWC Legal Experts, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Central Europe, reviewed the Manual. In February 1998, they finished the second edition of the Manual in order to update it in light of developments since the CWC entered into force on 29 April 1997. The Manual tries to increase understanding of the Convention by identifying its obligations and suggesting methods of meeting them. Education about CWC obligations and available alternatives to comply with these requirements can facilitate national response that are consistent among States Parties. Thus, the Manual offers options that can strengthen international realization of the Convention's goals if States Parties act compatibly in implementing them. Equally important, it is intended to build confidence that the legal issues raised by the Convention are finite and addressable. They are now nearing competition of an internet version of this document so that interested persons can access it electronically and can view the full text of all of the national implementing legislation it cites. The internet address, or URL, for the internet version of the Manual is http: //www.cwc.ard.gov. This paper draws from the Manual. It comparatively addresses approximately thirty

Nanofabrication is playing an ever increasing role in science and technology on the nanometer scale and will soon allow us to build systems of the same complexity as found in nature. Conventional methods that emerged from microelectronics are now used for the fabrication of structures for integrated circuits, microelectro-mechanical systems, microoptics and microanalytical devices. Nonconventional or alternative approaches have changed the way we pattern very fine structures and have brought about a new appreciation of simple and low-cost techniques. We present an overview of some of these methods, paying particular attention to those which enable large-scale production of lithographic patterns. We preface the review with a brief primer on lithography and pattern transfer concepts. After reviewing the various patterning techniques, we discuss some recent application issues in the fields of microelectronics, optoelectronics, magnetism as well as in biology and biochemistry.
Full Text Available INTRODUCTION : Laparoscopic splenectomy (LS is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4, 197-200 (2004], trauma [Ren et al., Surg Endosc 15(3, 324 (2001; Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4, 283-286 (2002], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45, 847-852 (2002]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported. MATERIALS AND METHODS : Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision. RESULTS : A total of 26 patients underwent LS. Twenty-two (85% of patients had spleen size more than 500 g (average weight being 942.55 g. Mean operative time was 214 min (45-390 min. The conversion rate was 11.5% ( n = 3. Average duration of stay was 5.65 days (3-30 days. Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease. CONCLUSION : Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

Full Text Available Diffusion tensor imaging (DTI has become the predominant modality for studying white matter integrity in multiple sclerosis (MS and other neurological disorders. Unfortunately, the use of DTI-based biomarkers in large multi-center studies is hindered by systematic biases that confound the study of disease-related changes. Furthermore, the site-to-site variability in multi-center studies is significantly higher for DTI than that for conventional MRI-based markers. In our study, we apply the Quantitative MR Estimation Employing Normalization (QuEEN model to estimate the four DTI measures: MD, FA, RD, and AD. QuEEN uses a voxel-wise generalized additive regression model to relate the normalized intensities of one or more conventional MRI modalities to a quantitative modality, such as DTI. We assess the accuracy of the models by comparing the prediction error of estimated DTI images to the scan-rescan error in subjects with two sets of scans. Across the four DTI measures, the performance of the models is not consistent: Both MD and RD estimations appear to be quite accurate, while AD estimation is less accurate than MD and RD; the accuracy of FA estimation is poor. Thus, in some cases when assessing white matter integrity, it may be sufficient to acquire conventional MRI sequences alone.

Full Text Available The protection of human rights in Mexico has, de jure, suffered an important change in the last years, given a new judicial interpretation delivered by the National Supreme Court of Justice that allows the use of conventionality control, which means, that it allows federal and state judges to verify the conformity of domestic laws with those established in the Inter-American Convention of Human Rights. To what extent domestic actors are protecting human rights using this new legal tool called conventionality control? In this article I explore whom and how is conventionality control being used in Mexico. Using N-Vivo Software I reviewed concluded decisions delivered by intermediate level courts (Collegiate Circuit Courts in three Mexican states. The evidence points that conventionality control is a very useful tool especially to defenders, who appear in sentences claiming compliance with the commitments Mexico has acquired when this country ratified the Convention.

Full Text Available BACKGROUND: The etiology of multiple sclerosis (MS has remained unclear, but a causative contribution of factors outside the central nervous system (CNS is conceivable. It was recently suggested that gut bacteria trigger the activation of CNS-reactive T cells and the development of demyelinative disease. METHODS: C57BL/6 (B6 mice were kept either under specific pathogen free or conventional housing conditions, immunized with the myelin basic protein (MBP-proteolipid protein (PLP fusion protein MP4 and the development of EAE was clinically monitored. The germinal center size of the Peyer's patches was determined by immunohistochemistry in addition to the level of total IgG secretion which was assessed by ELISPOT. ELISPOT assays were also used to measure MP4-specific T cell and B cell responses in the Peyer's patches and the spleen. Ear swelling assays were performed to determine the extent of delayed-type hypersensitivity reactions in specific pathogen free and conventionally housed mice. RESULTS: In B6 mice that were actively immunized with MP4 and kept under conventional housing conditions clinical disease was significantly attenuated compared to specific pathogen free mice. Conventionally housed mice displayed increased levels of IgG secretion in the Peyer's patches, while the germinal center formation in the gut and the MP4-specific TH17 response in the spleen were diminished after immunization. Accordingly, these mice displayed an attenuated delayed type hypersensitivity (DTH reaction in ear swelling assays. CONCLUSIONS: The data corroborate the notion that housing conditions play a substantial role in the induction of murine EAE and suggest that the presence of gut bacteria might be associated with a decreased immune response to antigens of lower affinity. This concept could be of importance for MS and calls for caution when considering the therapeutic approach to treat patients with antibiotics.

Patients undergoing conventional maintenance hemodialysis typically receive three sessions per week, each lasting 2.5–5.5 hours. Recently, the use of more intensive hemodialysis (>5.5 hours, three to seven times per week) has increased, but the effects of these regimens on survival are uncertain. We conducted a retrospective cohort study to examine whether intensive hemodialysis associates with better survival than conventional hemodialysis. We identified 420 patients in the International Quotidian Dialysis Registry who received intensive home hemodialysis in France, the United States, and Canada between January 2000 and August 2010. We matched 338 of these patients to 1388 patients in the Dialysis Outcomes and Practice Patterns Study who received in-center conventional hemodialysis during the same time period by country, ESRD duration, and propensity score. The intensive hemodialysis group received a mean (SD) 4.8 (1.1) sessions per week with a mean treatment time of 7.4 (0.87) hours per session; the conventional group received three sessions per week with a mean treatment time of 3.9 (0.32) hours per session. During 3008 patient-years of follow-up, 45 (13%) of 338 patients receiving intensive hemodialysis died compared with 293 (21%) of 1388 patients receiving conventional hemodialysis (6.1 versus 10.5 deaths per 100 person-years; hazard ratio, 0.55 [95% confidence interval, 0.34–0.87]). The strength and direction of the observed association between intensive hemodialysis and improved survival were consistent across all prespecified subgroups and sensitivity analyses. In conclusion, there is a strong association between intensive home hemodialysis and improved survival, but whether this relationship is causal remains unknown. PMID:22362910

Drawing on an analysis of qualitative interview data from a study of formalized same-sex relationships (civil partnerships) this paper examines the enduring significance of marriage and family as social institutions. In doing so, it intervenes in current debates in the sociology of family and personal life about how such institutions are undermined by reflexivity or bolstered by convention. Against the backdrop of dominating sociological frames for understanding the links between the changing nature of marriage and family and same-sex relationship recognition, the paper analyses the diverse and overlapping ways (including the simple, relational, strategic, ambivalent and critical ways) in which same-sex partners reflexively constructed and engaged with marriage and family conventions. My analysis suggests that instead of viewing reflexivity and convention as mutually undermining, as some sociologists of family and personal life do, it is insightful to explore how diverse forms of reflexivity and convention interact in everyday life to reconfigure the social institutions of marriage and family, but do not undermine them as such. I argue the case for recognizing the ways in which 'reflexive convention', or reflexive investment in convention, contributes to the continuing significance of marriage and family as social institutions. © London School of Economics and Political Science 2017.

Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors,

The use of music as a therapeutic tool in health and medicine dates back to ancient times. In modern Western medicine, music therapy has been available since the 1950s and is now often incorporated into conventional medicine care. Music therapy is a common modality that is used in hospital settings as part of complementary and integrative medicine programs. It is also a key therapeutic tool used within most integrative medicine programs at large cancer centers in the United States. When used in conjunction with conventional cancer treatments, music therapy has been found to help patients promote a better quality of life; better communicate their fear, sadness, or other feelings; and better manage stress, while alleviating physical pain and discomfort. In this article, we review the literature on the value of integrating music therapy in cancer care and describe the experience of music therapy at a large comprehensive cancer center and the benefits that patients with cancer obtain from this service.

Full Text Available Most tourists are not consciously engaging in ‘slow travel’, but a number of travel behaviours displayed by conventional tourists can be interpreted as slow travel behaviour. Based on Danish tourists’ engagement with the distances they travel across to reach their holiday destination, this paper explores unintended slow travel behaviours displayed by these tourists. None of the tourists participating in this research were consciously doing ‘slow travel’, and yet some of their most valued holiday memories are linked to slow travel behaviours. Based on the analysis of these unintended slow travel behaviours, this paper will discuss the potential this insight might hold for promotion of slow travel. If unappreciated and unintentional slow travel behaviours could be utilised in the deliberate effort of encouraging more people to travel slow, ‘slow travel’ will be in a better position to become integrated into conventional travel behaviour.

Full Text Available Since 1950 - when it was ratified – the European Convention on Human Rights has had a decisive impact on the legislation, jurisprudence and judicial practice of the signatory States of its text. A true “Charter” of Human Rights, the Convention - which was revised and amended by additional Protocols – enounced not only the human rights and fundamental freedoms, but also provided the framework of their legal protection, which laid the foundation of a new era in the history of human rights. Among others, our paper emphasizes also the fact that the European Convention on Human Rights sets not only the general principles of the EU law, principles that have the force of “Jus cogens” for all EU states in the field of human rights and fundamental freedoms, but also it guarantee them a proper legal protection. Since this reality was not yet fully noticed and analyzed in the juridical literature, we believe that, by emphasizing it, we bring a real contribution to a better understanding and to a better capitalization of the first “Charter” of European Human Rights.

This seminar is another excellent opportunity for those involved in preventing chemical weapons production and use to learn from each other about how the Chemical Weapons Convention (CWC) can become a foundation of arms control in Africa and around the world. The author is grateful to the staff of the Organization for the Prohibition of Chemical Weapons (OPCW) for inviting him to address this distinguished seminar. The views expressed in this paper are those of the authors alone, and do not represent the position of the government of the US nor or of any other institution. In 1993, as the process of CWC ratification was beginning, concerns arose that the complexity of integrating the treaty with national law would cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States Parties in how the Convention would be carried out. As a result the Manual for National Implementation of the Chemical Weapons Convention was prepared and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Manual was reviewed by the Committee of Legal Experts on National Implementation of the Chemical Weapons Convention, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Mica. In February 1998, the second edition of the Manual was published in order to update it in light of developments since the CWC entered into force on 29 April 1997. The second edition 1998 clarified the national implementation options to reflect post-entry-into-force thinking, added extensive references to national implementing measures that had been enacted by various States Parties, and included a prototype national implementing statute developed by the authors to provide a starting point for those whose national implementing

Retrospective comparative study at KKU Eye Center, Khon Kaen University. There were 342 patients with clinically suspected infectious endophthalmitis participated in the study. The vitreous specimens were inoculated in both blood culture bottles and on conventional culture media (blood agar, MacConkey agar, chocolate agar, Sabouraud dextrose agar and thioglycolate broth). The number of positive culture yields in both blood culture bottles and conventional media. Positive culture yields in both methods were found in 151 eyes (49.5%). There were 136 of 151 eyes (90.1%) with positive culture in blood culture bottles, whereas 99 of 151 eyes (65.6%) yielded positive cultures in conventional media. These findings were different with a statistical significance (P culture bottles and conventional media improved the yield. Blood culture bottles are superior to conventional media for vitreous culture in clinically suspected infectious endophthalmitis. Vitreous culture using blood culture bottles should be recommended as the primary method for microbiological diagnosis.

Full Text Available Technology-rich student-centered classrooms such as SCALE-UP and TEAL are designed to actively engage students. We examine what happens when the design of the classroom (conventional or teacher-centered versus student-centered classroom spaces is consistent or inconsistent with the teacher’s epistemic beliefs about learning and teaching (traditional or teacher-centered versus student-centered pedagogies. We compare two types of pedagogical approaches and two types of classroom settings through a quasiexperimental 2×2 factorial design. We collected data from 214 students registered in eight sections of an introductory calculus-based mechanics course given at a Canadian publicly funded two-year college. All students were given the Force Concept Inventory at the beginning and at the end of the 15-week-long course. We then focused on six teachers assigned to teach in the student-centered classroom spaces. We used qualitative observations and the Approaches to Teaching Inventory (ATI, a self-reported questionnaire, to determine the teachers’ epistemic beliefs (teacher-centered or student-centered and how these beliefs affected their use of the space and their students’ conceptual learning. We report four main findings. First, the student-centered classroom spaces are most effective when used with student-centered pedagogies. Second, student-centered classrooms are ineffective when used with teacher-centered pedagogies and may have negative effects for students with low prior knowledge. Third, we find a strong correlation between six instructors’ self-reported epistemic beliefs of student centeredness and their classes’ average normalized gain (r=0.91; p=0.012. Last, we find that some instructors are more willing to adopt student-centered teaching practices after using student-centered classroom spaces. These data suggest that student-centered classrooms are effective only when instructors’ epistemic framework of teaching and learning is

This paper synthesizes findings of the first phase in SEI`s PoleStar Project - a project aimed at developing long-term strategies and policies for sustainable development. Taking a global and long-range perspective, the paper aims to describe a theoretical framework for addressing sustainability, to identify emerging issues and outline directions for future action. The paper begins by setting today`s development and environmental challenges in historical context, and describing the scenario method for envisioning and evaluating alternative futures, and identifying propitious areas for policy and action. It next summarizes a detailed scenario based on conventional development assumptions, and discusses the implications of this scenario for demographic and economic patterns, energy and water resources, land resources and agriculture, and pollution loads and the environment to the year 2050. The conventional scenario relies in part on the sectorally-oriented work discussed in Papers 3 through 6 of the PoleStar Project report series, and makes use of the PoleStar System, software designed for integrated resource, environment and socio-economic accounting and scenario analysis (described in Paper 2). The paper then examines the critical risks to social, resource and environmental systems lying ahead on the conventional development path. Finally, the paper surveys the requirements for sustainability across a number of policy dimensions, and raises key questions for the future. The PoleStar Project is proceeding to examine a range of alternative development scenarios, in the context of the work of the regionally-diverse Global Scenario Group, convened by SEI. The hope remains to offer wise counsel for a transition to an equitable, humane and sustainable future for the global community. 144 refs, 30 figs, 9 tabs

Full Text Available Arthritides are acute or chronic inflammation of one or more joints. The most common types of arthritis are osteoarthritis and rheumatoid arthritis, but there are more than 100 different forms. Right and early diagnosis is extremely important for the prevention of eventual structural and functional disability of the affected joint. Imaging findings, especially those of advanced level imaging, play a major role in diagnosis and monitor the progression of arthritis or its response to therapy. The objective of the review is to discuss the findings of conventional and advanced radiological imaging of most common arthritides and to present a simplified approach for their radiological evaluation.

Rotary forming is one of the promising incremental processes. However, a wide industrial implementation of it strongly depends on the deep understanding of the mechanics of this process. This paper attempts to develop this understanding via a comparison of the rotary forming process with conventional flaring. Both the processes were simulated using commercial metal forming software QForm. The results of the simulation were validated by comparison with the experimental trials. The main focus was made on the triaxiality states taking place during forming, as it seems to be the main factor determining the success of the process.

In toroidal fusion devices it is relatively easy that electrons achieve relativistic velocities, so to simulate runaway electrons and other high energy phenomena a nonrelativistic guiding center formalism is not sufficient. Relativistic guiding center equations including flute mode time dependent field perturbations are derived. The same variables as used in a previous nonrelativistic guiding center code are adopted, so that a straightforward modifications of those equations can produce a relativistic version.

The Chemical Weapons Convention (CWC) offers a unique challenge to the US system of constitutional law. Its promise of eliminating what is the most purely genocidal type of weapon from the world`s arsenals as well as of destroying the facilities for producing these weapons, brings with it a set of novel legal issues. The reservations about the CWC expressed by US business people are rooted in concern about safeguarding confidential business information and protecting the constitutional right to privacy. The chief worry is that international verification inspectors will misuse their power to enter commercial property and that trade secrets or other private information will be compromised as a result. It has been charged that the Convention is probably unconstitutional. The author categorically disagrees with that view and is aware of no scholarly writing that supports it. The purpose of this presentation is to show that CWC verification activities can be implemented in the US consistently with the traditional constitutional regard for commercial and individual privacy. First, he very briefly reviews the types of verification inspections that the CWC permits, as well as some of its specific privacy protections. Second, he explains how the Fourth Amendment right to privacy works in the context of CWC verification inspections. Finally, he reviews how verification inspections can be integrated into these constitutional requirements in the SU through a federal implementing statute.

The antibacterial activity of conventional glass ionomer cement against three different microorganism strains alone and following incorporation of 1, 2 and 3% Benzalkonium Chloride and Cetylpyridinium Chloride was evaluated. Agar diffusion method was used to determine the inhibitory effect of the conventional glass ionomer cement ChemFlex on Streptococcus mutans, Lactobacillus casei and Actinomyces viscosus. Bacterial strains were inoculated into BHIB, and incubated in an anaerobic atmosphere (37 °C). From the bacteria grown in the liquid medium, the density of the inoculum was set to be equivalent to McFarland 2 standard. In Shaedler agar, 350 μL of the bacterial suspension were equally spread. Specimens (4 mm × 6 mm) were prepared from the cement without and with addition of 1, 2 and 3% Benzalkonium Chloride and Cetylpyridinium Chloride. The inhibition zones were determined after 48 hours, after 2, 7 and 21 days of incubation. The combination ChemFlex + Benzalkonium Chloride has the best effect on the three analysed bacteria. The Benzalkonium Chloride antibacterial compound has a stronger antibacterial effect than Cetylpyridinium Chloride. Glass ionomer cements can potentially be used as a medium for slow release of active antimicrobial components, and they have the potential to improve clinical outcomes of the cements (Tab. 3, Fig. 3, Ref. 31).

In India there is a shortage of energy resources. The conventional sources are incapable to mitigate this problem by providing sufficient amount of energy. The crisis is gradually becoming more acute particularly in the countryside thus hampering the economic growth. To deal with this problem some new strategies have been envisaged. Generation of energy to meet daily requirement from non-conventional sources is one of the steps in this regard. With the increasing popularity of biogas plants in rural as well as in urban areas of India, it has become essential to find various location specific organic substances that can be used as feed material in biogas plant. In this study we have concentrated on use of cow dung and water hyacinth as feed material in biogas plants. The objective of the study is to assess the suitability of using mixture of cow dung and water hyacinth as feed material in biogas plants. Attempt has been made to find out the optimum proportion of cow dung and water hyacinth. The 1:1 mixture of cow dung and water hyacinth is the optimum proportion as per the study conducted. (author)

Full Text Available Legislation on global and regional level in the field of environmental protection is characterized by the adoption of international conventions and agreements that attempt to regulate this matter legally. As an extremely important area, which exceeds the boundaries of nation-state and as a global environmental problem, the issues of environmental protection are a major concern to international organizations. It is directly linked to reducing the jurisdiction of the States and transfer of competences to international organizations and institutions in order to solve the problems in a global experience. In order to overcome the problems regarding the implementation of international documents, the creation of certain policies by international organizations and institutions is required to promote the idea of environmental protection as a basic mo$ o of the global world. Taking into account the recommendations of Brundtland Commission, humanity has a moral obligation to preserve natural resources for future generations. Main objective of this article is the presentation of research on the implementation of the Aarhus Convention and the proposal of measures for the creation of ideas and policies on improving access to information in the field. The research is done with the students from the faculty of Security which accessed the information in environmental matters.

Until recently, conventional dental radiology was performed by dentists and orofacial surgeons. Due to the rapid development of radiological technique, the demand of radiological advice is increasing. The radiologists see more and more dental patients in their daily routine. The aim of this article is to give an overview on established dental radiology and a glimpse into the future. Conventional dental radiology and digital radiography are presently in use. Intraoral technique comprises dental films, bite-wing views and occlusal radiographs. Panoramic views and cephalometric radiographs are done with extraoral technique. Digital radiography lacks all processes in behalf of film development. It leads to dose reduction and enables image manipulation. (orig.) [German] Die konventionelle Radiologie in der Zahnheilkunde (Dentalradiologie) wurde hauptsaechlich von den niedergelassenen Zahnaerzten und Mund-, Kiefer- und Gesichtschirurgen betrieben. Aufgrund der rasanten Entwicklung in der radiologischen Methodik wird die fachaerztliche Unterstuetzung durch den Radiologen immer notwendiger, und die raschen Fortschritte erfordern eine zunehmende Zusammenarbeit dieser medizinischen Faecher. Die fachspezifische Anforderung an den Radiologen tritt immer haeufiger im Routinebetrieb auf. Ziel dieses Artikels ist die Aufstellung der derzeit eingesetzten Technik sowie ein Ausblick in die nahe Zukunft. Prinzipiell wird zwischen der konventionellen Dentalradiologie und der digitalen Radiographie unterschieden. Die Dentalradiologie setzt sich aus der intraoralen Technik (Zahnfilme, Bissfluegelaufnahmen, Aufbissaufnahme) und der extraoralen Technik (Panoramaaufnahmen, Panoramaschichtaufnahmen, Fernroentgen) zusammen. Die digitale Radiographie ermoeglicht die Umgehung der konventionellen Entwicklungsverfahren, eine Strahlendosisreduktion und bietet die Moeglichkeit der Bildverarbeitung. (orig.)

For the past decade, we have been developing techniques for monitoring pre- and postharvest diseases of tree fruit, nuts and vines at the UC Kearney Research and Extension Center (KREC). We have also advanced new methods to monitor pathogen resistance to fungicides, which growers can now use to make decisions on disease management. Although accurate, the conventional techniques are time-consuming and only provide results after 5 to 21 days. Molecular methods offer the possibility of faster, m...

Background. Tumefactive demyelination (TD) is a relatively uncommon entity which mimics other focal intracranial lesions. Conventional radiological findings in tumefactive demyelination have been well described. However, DTI and MRS findings in TD have not been studied in detail. Purpose. To evaluate the usefulness of conventional magnetic resonance imaging (MRI), multivoxel 1H spectroscopy (MRS) and diffusion tensor imaging (DTI) in diagnosis and follow-up of TD of the brain. Material and Methods. Clinical and imaging findings of 18 patients were reviewed. MR imaging data which included conventional imaging as well as MRS and DTI were reviewed. At TE 135ms MRS various metabolite ratios were calculated at different depths of the demyelinating lesions. At TE 30 ms, glutamate-glutamine (GLX-2.1-2.5 ppm) was compared in the lesion to the contralateral normal side. DTI data were available for 15 patients and Dav (mean diffusivity) and trace values were recorded from central and peripheral layers of the index lesion. Histopathological (9 patients) and therapeutic response (9 patients) on follow-up imaging were taken as the diagnostic criterion. In addition, the follow-up MRI scans available were also reviewed. Results. Characteristic peripheral 'broken ring' type of contrast enhancement was noted in 12 cases. Two or three concentric distinct zones were noted on imaging with distinct metabolic and structural signature in most cases. On TE 135ms, the central part showed variable Choline (Cho) and significantly low N-Acetyl Aspartate (NAA). DTI demonstrated high Dav and very low trace value in this zone. The intermediate area showed higher Cho and lower NAA compared to contralateral normal side. The outermost layer, which corresponded to the contrast enhancing areas on MRI, showed high Cho, lower NAA, and restricted diffusion on DTI. The GLX increase was noted in tumefactive lesions. Lactate was observed in all patients and it appeared higher at the center

Summary Magnetic resonance imaging (MRI) provides an in vivo assessment of cortical and subcortical regions affected in Parkinson’s disease (PD). This review summarizes the most important conventional and non-conventional MRI techniques applied in this field. Standard neuroimaging techniques have played a marginal role in the diagnosis and follow-up of PD, essentially being used only to discriminate atypical syndromes from PD, to exclude secondary causes such as vascular lesions, and to confirm the absence of specific imaging features found in atypical parkinsonisms. However, non-conventional MRI techniques, i.e. new neuroimaging approaches such as magnetic resonance spectroscopy, diffusion tensor imaging, and functional MRI, may allow the detection of structural, functional and metabolic changes useful not only for differential diagnosis, but also for early diagnosis and outcome and treatment monitoring in PD. In addition, we illustrate the advantages of high-field MRI over lower magnetic fields, highlighting the great potential of advanced neuroimaging techniques. PMID:24125556

E-cigarette 'vaping conventions' provide a venue for user social networking, parties, and 'try before you buy' access to a wide range of e-cigarette products. This study identifies and describes vaping conventions, raising awareness of this potentially problematic practice. Conventions were identified via Google searches in April and May 2014 and August 2015. Details captured included location, sponsors, admission cost, event features, and promotions. 41 distinct organizations have planned 90 vaping conventions in 37 different locations since 2010. Conventions promoted access to a wide range of product vendors, seminars, social interactions with other users, parties, gifts, vaping contests, and other events. E-cigarette use at conventions was encouraged. Vaping conventions promote e-cigarette use and social norms without public health having a voice to educate attendees about negative consequences of use. Future research should focus on the effects of attending these conventions on attendees and on indoor air quality in vapor-filled convention rooms.

A precondition for the appropriate analysis of conceptual models is not only their syntactic correctness but also their semantic comparability. Assuring comparability is challenging especially when models are developed by different persons. Empirical studies show that such models can vary heavily, especially in model element naming, even if they express the same issue. In contrast to most ontology-driven approaches proposing the resolution of these differences ex-post, we introduce an approach that avoids naming differences in conceptual models already during modeling. Therefore we formalize naming conventions combining domain thesauri and phrase structures based on a lin-guistic grammar. This allows for guiding modelers automatically during the modeling process using standardized labels for model elements. Our approach is generic, making it applicable for any modeling language.

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corrections are included. We propose such a scheme, Supersymmetry Parameter Analysis SPA, based on a consistent set of conventions and input parameters. A repository for computer programs is provided which connect parameters in different schemes and relate the Lagrangian parameters to physical observables at LHC and high energy e+e- linear collider experiments, i.e., masses, mixings, decay widths and production cross sections for supersymmetric particles. In addition, programs for calculating high-precision low energy observables, the density of cold dark matter (CDM) in the universe as well as the cross sections for CDM search experiments are included. The SPA scheme still requires extended efforts on both the theoretical and experimental side before data can be evaluated in the future at the level of the d...

Full Text Available Humanity faces the challenge of achieving the sustainability of water resources supply for the satisfaction of human needs and ofensuring the sustainability of the natural ecosystems for the achievement of sustainable human development and the quality of life of present and future generations. For this reason the recognition of access to water as a Human Right has fundamental significance. We proceed to analyze the international instruments that provide content and legal basis to the human right to water and the obligations of States. In this context, we deal with the constitutional reception of human right to water in Argentina in the constitutional reform of 1994 and the control of conventionality as guarantor of access to water, which has led to different domestic courts to consider cases in which a violation ofthe right to water was proved.
We note substantial inconsistency among authors discussing rotational motions observed with inertial seismic sensors (and much more so in the broader topic of rotational phenomena). Working from physics and other precedents, we propose standard terminology and a preferred reference frame for inertial sensors (Fig. 1) that may be consistently used in discussions of both finite and infinitesimal observed rotational and translational motions in seismology and earthquake engineering. The scope of this article is limited to observations because there are significant differences in the analysis of finite and infinitesimal rotations, though such discussions should remain compatible with those presented here where possible. We recommend the general use of the notation conventions presented in this tutorial, and we recommend that any deviations or alternatives be explicitly defined.

Tenants in retirement housing given a 6-week program of Feldenkrais exercises were compared with a group given conventional exercises and with control groups given no exercises. Analysis of covariance of preliminary and subsequent measurements failed to yield any significant differences between groups. Measurements included height, weight, blood pressure, heart rate, balance, flexibility, morale, self-perceived health status and level of performance of activities of daily living, also the number of body parts difficult to move or giving rise to pain. Several possible reasons are given for the results. Attention is drawn to the necessity of medically screening and monitoring elderly registrants for exercise programs since it is apparent that some sign up who should not.

Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed

Cancer is defined as the abnormal proliferations of cells which could occur in any tissue and can cause life-threatening malignancies with high financial costs for both patients and health care system. Plant-derived secondary metabolites are shown to have positive role in various diseases and conditions. The aim of the present study is to summarize clinical evidences on the benefits of phytochemicals as adjuvant therapy along with conventional anticancer therapies. Electronic databases including Pubmed, Scopus and Cochrane library were searched with the keywords "chemotherapeutic", "anticancer", "antineoplastic" or "radiotherapy" with "plant", "extract", "herb", or "phytochemical", until July 2015. Only clinical studies were included in this review. The findings showed that positive effects of phytochemicals are due to their direct anticarcinogenic activity, induction of relief in cancer complications, as well as their protective role against side effects of conventional chemotherapeutic agents. Results obtained from current review demonstrated that numerous phytochemical agents from different chemical categories including alkaloid, benzopyran, coumarin, carotenoid, diarylheptanoid, flavonoid, indole, polysaccharide, protein, stilbene, terpene, and xanthonoid possess therapeutic effect in patients with different types of cancer. Polyphenols are the most studied components. Curcumin, ginsenosides, lycopene, homoharringtonine, aviscumine, and resveratrol are amongst the major components with remarkable volumes of clinical evidence indicating their direct anticancer activities in different types of cancer including hepatocarcinoma, prostate cancer, leukemia and lymphoma, breast and ovarian cancer, and gastrointestinal cancers. Cannabinoids, cumarin, curcumin, ginsenosides, epigallocatechin gallate, vitexin, and salidroside are phytochemicals with significant alleviative effect on synthetic chemotherapy- induced toxicities. There is lack of evidence from clinical

Additive manufacturing (AM) processes enable the production of functional parts with complex geometries, multi-materials as well as individualized mass production. Another significant benefit of AM is the ability to produce optimized geometries with near perfect strength to weight ratios. For several years now, the topology optimization techniques assist the designers in order to develop components that have a good material distribution in order to reduce the weight ensuring the request stiffness. Therefore, the topology optimization generates concepts based on the subtractive approach and usually these geometries require a further post processing in order to obtain a geometry "ready to produce" that represents a compromise between the topologic result and the manufacturing constraints. The advent of the AM opens new scenarios in terms of definition of innovative geometries that are not feasible with the conventional processes (such as lattice structures). In order to exploit the AM capabilities, new topology optimization tools are emerging that allow to define innovative concepts that could reach structural performance greater than the result obtainable with conventional topology optimization. In this paper the Authors have studied a new concept design and the performance improvement, of PIN installation equipment, used for thin-walled aerospace workpiece, in order to solve critical dimensioning issues, due to the overcoming of the allowable range tolerances (strain and displacement). Topology optimization has been applied in order to define a new concept design able to satisfy the functionality requirements. Moreover, it has been conducted a study to evaluate the possible advantages offered by the integration of the lattice structure in the topology design in order to improve the performance in terms of weight and structural characteristics.

means to achieving fast and stable economic growth. Nonetheless, the degree of endogenous technical innovation in Brazil remains very low. This paper explores the conjecture that the latter result is a consequence of the hegemonic view of development. The first section presents some quantitative and qualitative data to support our assertion about the innovativeness of the Brazilian economy. The second section argues that the “view of development” may be profitably treated as a “convention”, a set of beliefs shared by decision-makers and used to identify the main issues which a development strategy has to tackle and the appropriate means to address such issues. A development convention contains also a “negative” agenda — issues and solutions which should be avoided. The same section then analyses the development convention which was hegemonic from the nineties to the date of the paper (2002 and the implications of its positive and negative agendas for technological development, assuming such convention had worked as its supporters supposed it would. It argues that the theoretical results are consistent with the facts described in the first section. The last section comments the actual working of the development convention, arguing that it stressed the main technological features present in the “pure form” of the convention and concludes with a brief discussion of the role of innovation in a new development convention which seemed to be arising at that time.

Limited evidence is available comparing digital versus conventional impressions from the point of view of patient preference. The purpose of this systematic review was to identify and summarize the available literature related to patient-centered outcomes for digital versus conventional impression techniques. The databases Medline, Cochrane, Science Direct, Scopus, and Embase were electronically searched and complemented by hand searches. All published papers available on the databases from 1955 to July 2016 were considered for title and abstract analysis. A total of 2943 articles were initially identified through database searches, of which only 5 met the inclusion criteria for qualitative analysis. Four studies comparing patient-reported outcome measures (PROMs) between conventional and digital impressions revealed that the digital technique was more comfortable and caused less anxiety and sensation of nausea. Only 1 study reported no difference between the techniques regardless of patient comfort. Two studies reported a shorter procedure for the conventional technique, whereas 3 studies reported a shorter procedure for the digital technique. A lack of clinical studies addressing patient outcomes regarding digital prosthodontic treatments was observed among the included articles. However, current evidence suggests that patients are more likely to prefer the digital workflow than the conventional techniques.

Relative equilibria (REs) and relative periodic orbits (RPOs) are ubiquitous in symmetric Hamiltonian systems and occur, for example, in celestial mechanics, molecular dynamics, and rigid body motion. REs are equilibria, and RPOs are periodic orbits of the symmetry reduced system. Relative Lyapunov...... center bifurcations are bifurcations of RPOs from REs corresponding to Lyapunov center bifurcations of the symmetry reduced dynamics. In this paper we first prove a relative Lyapunov center theorem by combining recent results on the persistence of RPOs in Hamiltonian systems with a symmetric Lyapunov...

Good biosecurity procedures are crucial for healthy animal production. The aim of this study was to quantify the level of biosecurity on conventional broiler farms in Europe, following a standardized procedure, thereby trying to identify factors that are amenable to improvement. The current study used a risk-based weighted scoring system (biocheck.ugent ®) to assess the level of biosecurity on 399 conventional broiler farms in 5 EU member states. The scoring system consisted of 2 main categories, namely external and internal biosecurity, which had 8 and 3 subcategories, respectively. Biosecurity was quantified by converting the answers to 97 questions into a score from 0 to 100. The minimum score, "0," represents total absence of any biosecurity measure on the broiler farm, whereas the maximum score, "100," means full application of all investigated biosecurity measures. A possible correlation between biosecurity and farm characteristics was investigated by multivariate linear regression analysis. The participating broiler farms scored better for internal biosecurity (mean score of 76.6) than for external biosecurity (mean 68.4). There was variation between the mean biosecurity scores for the different member states, ranging from 59.8 to 78.0 for external biosecurity and from 63.0 to 85.6 for internal biosecurity. Within the category of external biosecurity, the subcategory related to "infrastructure and vectors" had the highest mean score (82.4), while the subcategory with the lowest score related to biosecurity procedures for "visitors and staff" (mean 51.5). Within the category of internal biosecurity, the subcategory "disease management" had the highest mean score (65.8). In the multivariate regression model a significant negative correlation was found between internal biosecurity and the number of employees and farm size. These findings indicate that there is a lot of variation for external and internal biosecurity on the participating broiler farms
National Science Teachers Association (NSTA) conventions are traditionally composed of short workshops, half or full day workshops, and lectures on science teaching or education research. Occasional science lectures such as the AGU lecture offer science content information. The National Earth Science Teachers Association (NESTA) will join the National Association of Geoscience Teachers (NAGT), American Geophysical Union (AGU), and the American Geological Institute (AGI) to bring teachers a suite of exciting and informative events at the (NSTA) 2002 convention. Events begin with a guided learning field trip to Mission Trails Regional Park and Torrey Pines State Reserve where Earth and space science teachers experience a model of constructivist leaning techniques. Most field trips are a "show and tell" experience, designed to transmit knowledge from the field trip leader to the field trip participants. In the "guided learning" environment, the leader serves as a facilitator, asking questions, guiding participants to discover concepts for themselves. Participants examine selected processes and features that constitute a constructivist experience in which knowledge acquired at any given location builds on knowledge brought to the site. Employing this strategy involves covering less breadth but greater depth, modeling the concept of "less is more." On Thursday NESTA will host two Share-a-thons. These are not what a person would think of as a traditional workshop where presenter makes a presentation then the participants work on an activity. They could be called the flea market of teaching ideas. Tables are set around the perimeter of a room where the presenters are stationed. Teachers move from table to table picking up information and watching short demonstrations. The Earth and Space Science Resource Day on Friday will focus on teachers needs. Starting with breakfast, teachers will hear from Soames Summerhays, Naturalist and President of Summerhays Films, about how he

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corrections are included. We propose such a scheme, Supersymmetry Parameter Analysis SPA, based on a consistent set of conventions and input parameters. A repository for computer programs is provided which connect parameters in different schemes and relate the Lagrangian parameters to physical observables at LHC and high energy e + e- linear collider experiments, i.e., masses, mixings, decay widths and production cross sections for supersymmetric particles. In addition, programs for calculating high-precision low energy observables, the density of cold dark matter (CDM) in the universe as well as the cross sections for CDM search experiments are included. The SPA scheme still requires extended efforts on both the theoretical and experimental side before data can be evaluated in the future at the level of the desired precision. We take here an initial step of testing the SPA scheme by applying the techniques involved to a specific supersymmetry reference point.
Not very much is written in the literature about decisions made by researchers and the justifications on method as a result of a particular clinical problem, together with an appropriate and congruent theoretical perspective, particularly for Glaserian grounded theory. I contend the utilisation of symbolic interactionism as a theoretical perspective to inform and guide the evolving research process and analysis of data when using classic or Glaserian grounded theory (GT) method, is not always appropriate. Within this article I offer an analysis of the key issues to be addressed when contemplating the use of Glaserian GT and the utilisation of an appropriate theoretical perspective, rather than accepting convention of symbolic interactionism (SI). The analysis became imperative in a study I conducted that sought to explore the concerns, adaptive behaviours, psychosocial processes and relevant interactions over a 12-month period, among newly diagnosed persons with end stage renal disease, dependent on haemodialysis in the home environment for survival. The reality of perception was central to the end product in the study. Human ethics approval was granted by six committees within New South Wales Health Department and one from a university.

As our knowledge of host-microbial interactions within the oral cavity increases, future treatments are likely to be more targeted. For example, efforts to target a single species or key virulence factors that they produce, while maintaining the natural balance of the resident oral microbiota that acts to modulate the host immune response would be an advantage. Targeted approaches may be directed at the black-pigmented anaerobes, Porphyromonas gingivalis and Prevotella intermedia, associated with periodontitis. Such pigments provide an opportunity for targeted phototherapy with high-intensity monochromatic light. Functional inhibition approaches, including the use of enzyme inhibitors, are also being explored to control periodontitis. More general disruption of dental plaque through the use of enzymes and detergents, alone and in combination, shows much promise. The use of probiotics and prebiotics to improve gastrointestinal health has now led to an interest in using these approaches to control oral disease. More recently the potential of antimicrobial peptides and nanotechnology, through the application of nanoparticles with biocidal, anti-adhesive and delivery capabilities, has been explored. The aim of this review is to consider the current status as regards non-conventional treatment approaches for oral infections with particular emphasis on the plaque-related diseases. PMID:25668296

The local and systemic humoral immune responses to rotavirus were studied in six conventional neonatal calves. Attenuated bovine rotavirus was administered either orally or directly into an isolated intestinal loop. The parameters monitored were neutralizing rotavirus antibody in serum, immunofluorescent and neutralizing rotavirus antibody in intestinal loop washings, and rotavirus antibody-producing cells in intestinal mucosa. An antibody response was observed in the serum and intestinal secretions from one calf only. Viral replication was not detected in the isolated intestinal loop. Rotavirus antibody-producing cells were found in the intestinal mucosa of five calves. Double staining revealed that most of these cells produced antibody of the immunoglobulin A class. The conclusions were: (i) a previously described system to detect rotavirus antibody-producing cells can be used to study immune responses in neonatal calves, (ii) the class or subclass of antibody in rotavirus antibody-producing cells can be determined by double immunofluorescent staining, (iii) neonatal calves respond to rotavirus inoculation with a local immunoglobulin A response, and (iv) most of the rotavirus antibody-producing cells are located in the mucosa of the proximal small intestine.
After that, when more than 60 years ago in the Japanese city of Minamata there was caused a mass poisoning of residents by seafood contaminated with mercury, Minamata Convention on Mercury came into force on August 16, 2017. To date, the Convention has been signed by 128 States, the signatories of the Convention and ratified by 83 States - Parties to the Convention. The Convention imposes a number of obligations on the Parties to the Convention, including the reporting obligation. The paper analyses the reporting obligations of the Parties to the Convention, which are in force after the entry into force of the Convention, pursuant to the provisions contained therein. In addition, the existing sources of quantitative data on mercury in Poland are characterized.

Alternative institutional settings have been established for the care of pregnant women who prefer little or no medical intervention. The settings may offer care throughout pregnancy and birth, or only during labour; they may be part of hospitals or freestanding entities. Specially designed labour rooms include bedroom-like rooms, ambient rooms, and Snoezelen rooms. Primary: to assess the effects of care in an alternative institutional birth environment compared to care in a conventional setting. Secondary: to determine if the effects of birth settings are influenced by staffing, architectural features, organizational models or geographical location. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 March 2012). All randomized or quasi-randomized controlled trials which compared the effects of an alternative institutional birth setting to a conventional setting. We used the standard methods of the Cochrane Collaboration Pregnancy and Childbirth Group. Two review authors evaluated methodological quality. We performed double data extraction and presented results using risk ratios (RR) and 95% confidence intervals (CI). Ten trials involving 11,795 women met the inclusion criteria. We found no trials of freestanding birth centres or Snoezelen rooms. Allocation to an alternative setting increased the likelihood of: no intrapartum analgesia/anesthesia (six trials, n = 8953; RR 1.18, 95% CI 1.05 to 1.33); spontaneous vaginal birth (eight trials; n = 11,202; RR 1.03, 95% CI 1.01 to 1.05); breastfeeding at six to eight weeks (one trial, n = 1147; RR 1.04, 95% CI 1.02 to 1.06); and very positive views of care (two trials, n = 1207; RR 1.96, 95% CI 1.78 to 2.15). Allocation to an alternative setting decreased the likelihood of epidural analgesia (eight trials, n = 10.931; RR 0.80, 95% CI 0.74 to 0.87); oxytocin augmentation of labour (eight trials, n = 11,131; RR 0.77, 95% CI 0.67 to 0.88); instrumental vaginal birth (eight trials, n = 11,202; RR 0

Packaging waste forms a significant part of municipal solid waste and has caused increasing environmental concerns, resulting in a strengthening of various regulations aimed at reducing the amounts generated. Among other materials, a wide range of oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination. Recently, significant progress has been made in the development of biodegradable plastics, largely from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers. The expansion in these bio-based materials has several potential benefits for greenhouse gas balances and other environmental impacts over whole life cycles and in the use of renewable, rather than finite resources. It is intended that use of biodegradable materials will contribute to sustainability and reduction in the environmental impact associated with disposal of oil-based polymers. The diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all 'good' or petrochemical-based products are all 'bad'. This paper discusses the potential impacts of biodegradable packaging materials and their waste management, particularly via composting. It presents the key issues that inform judgements of the benefits these materials have in relation to conventional, petrochemical-based counterparts. Specific examples are given from new research on biodegradability in simulated 'home' composting systems. It is the view of the authors that biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.

Entanglement is a physical phenomenon that each state cannot be described individually. Entanglement entropy gives quantitative understanding to the entanglement. We use decomposition of the Hilbert space to discuss properties of the entanglement. Therefore, partial trace operator becomes important to define the reduced density matrix from different centers, which commutes with all elements in the Hilbert space, corresponding to different entanglement choices or different observations on entangling surface. Entanglement entropy is expected to satisfy the strong subadditivity. We discuss decomposition of the Hilbert space for the strong subadditivity and other related inequalities. The entanglement entropy with centers can be computed from the Hamitonian formulations systematically, provided that we know wavefunctional. In the Hamitonian formulation, it is easier to obtain symmetry structure. We consider massless p-form theory as an example. The massless p-form theory in (2p+2)-dimensions has global symmetry, similar to the electric-magnetic duality, connecting centers in ground state. This defines a duality structure in centers. Because it is hard to exactly compute the entanglement entropy from partial trace operator, we propose the Lagrangian formulation from the Hamitonian formulation to compute the entanglement entropy with centers. From the Lagrangian method and saddle point approximation, the codimension two surface term (leading order) in the Einstein gravity theory or holographic entanglement entropy should correspond to non-tensor product decomposition (center is not identity). Finally, we compute the entanglement entropy of the SU(N) Yang-Mills lattice gauge theory in the fundamental representation using the strong coupling expansion in the extended lattice model to obtain spatial area term in total dimensions larger than two for N>1.

The aim of this in vitro study was to compare fluorescence-aided caries excavation with conventional excavation based on the Martens and Vickers hardness of dentin at the cavity floor after caries removal. In total, 20 extracted human teeth with dentin caries were bisected through the lesion center into two halves, which were assigned to either the fluorescence-aided caries excavation group or the conventional excavation group. After the treatment, embedding, mounting, and polishing, a line of indentations from the dental pulp across the sound dentin to the cavity floor was made on each sample. The data were compared with Student's t and Mann-Whitney U tests. The calculated Vickers hardness of the sound dentin was 57 ± 10 kg/mm(2) in the fluorescence-aided caries excavation group and 59 ± 8 kg/mm(2) in the conventional excavation group, which is consistent with the previous studies. The absolute and relative Martens hardness measurements of the cavity floor were 224 ± 93 N/mm(2) and 46 ± 17%, respectively, in the fluorescence-aided caries excavation group and 412 ± 75 N/mm(2) and 81 ± 14%, respectively, in the conventional excavation group. Based on either the Martens or Vickers hardness, both the absolute and relative microhardness measurements of the cavity floor after fluorescence-aided caries excavation were significantly lower than the values obtained by conventional excavation. Fluorescence-aided caries excavation showed the tissue-preserving property and was more conservative than the conventional excavation in this in vitro study.
The Department of Veterans Affairs (VA) adopts as final an interim final rule that amends its medical regulation that governs Vet Center services. The National Defense Authorization Act for Fiscal Year 2013 (the 2013 Act) requires Vet Centers to provide readjustment counseling services to broader groups of veterans, members of the Armed Forces, including a member of a reserve component of the Armed Forces, and family members of such veterans and members. This final rule adopts as final the regulatory criteria to conform to the 2013 Act, to include new and revised definitions.

Full Text Available Background : Dermatofibroma sometimes clinically presents as a nodular lesion without gross skin surface change. Clinicopathologic features of this variant of dermatofibroma have not been evaluated. Aims : To assess clinicopathologic features of dermatofibroma presenting as a subcutaneous nodule. Methods : This study reviewed the clinical and histological features of 42 cases of subcutaneous dermatofibromas and compared them with 95 cases of conventional dermatofibroma. Results : Dermatofibroma without gross skin surface change was associated with a shorter pre-diagnosis duration than conventional dermatofibroma. Increase in size during the pre-diagnosis period was significantly more frequent in the conventional type. In addition, these dermatofibromas were more likely than the conventional type to occur in the head and neck region. Although tumor depth was deeper than in the conventional type, less than half of the dermatofibromas without gross skin surface change were found histologically to be "subcutaneous" or "deep-penetrating dermatofibroma". Subcutaneous extension was more frequent in these dermatofibromas while focal stromal hyalinization and hemosiderin deposits were more common in the conventional type. Limitations: This study is a retrospective, single center design. Conclusion : The present study suggests that dermatofibroma without gross skin surface change is a variant type with distinct clinical and histological features that distinguish them from conventional dermatofibroma.
Full Text Available Germany’s educational system has undergone a series of transformations during the last 40 years. In recent years, marked increases in enrolment have occurred. In response, admission requirements have been relaxed and new universities have been established.Academic distance education in the former Federal Republic of Germany (West Germany was ushered in by the educational radio broadcasts around the end of the 1960s. Aside from the formation of the FernUniversität (Open University in West Germany in 1975, there were significant developments in distance education occurring at the major universities in the German Democratic Republic (East Germany. After German reunification in 1990, the new unitary state launched programs to advance the development of distance education programs at conventional universities.Germany’s campus-based universities (Präsenzuniversitäten created various entities, including central units and consortia of universities to design and market distance education programs. Hybridisation provides the necessary prerequisites for dual mode delivery, such as basic and continuing education programs, as well as for the combination of distance and campus-based education (Präsenzstudium. Hybridisation also has also opened the door for the creation of new programs.Following an initial phase in which distance education research is expected to centralize a trend towards decentralisation is likely to follow. The German Association for Distance Education (AG-F offers a viable research network in distance education.

The objective of this study was to evaluate the potential of exercises performed in a 2D video-capture virtual reality (VR) training environment to improve upper limb motor ability in stroke patients compared to those performed in conventional therapy. A small sample randomized control trial, in an outpatient rehabilitation center with 12 patients with chronic stroke, aged 33-80 years, who were randomly allocated to video-capture VR therapy and conventional therapy groups. All patients participated in four clinical evaluation sessions (pre-test 1, pre-test 2, post-test, follow-up) and nine 45-minute intervention sessions over a 3-week period. Main outcomes assessed were Body Structure and Function (impairment: Fugl-Meyer Assessment [FMA]; Composite Spasticity Index [CSI]; Reaching Performance Scale for Stroke), Activity (Box and Blocks; Wolf Motor Function Test [WMFT]), and Participation (Motor Activity Log) levels of the International Classification of Functioning. Improvements occurred in both groups, but more patients in the VR group improved upper limb clinical impairment (FMA, CSI) and activity scores (WMFT) and improvements occurred earlier. Patients in the VR group also reported satisfaction with the novel treatment. The modest advantage of VR over conventional training supports further investigation of the effect of video-capture VR or VR combined with conventional therapy in larger-scale randomized, more intense controlled studies.

A workshop to obtain input from industry on the establishment of the Precision Joining Center (PJC) was held on July 10--12, 1991. The PJC is a center for training Joining Technologists in advanced joining techniques and concepts in order to promote the competitiveness of US industry. The center will be established as part of the DOE Defense Programs Technology Commercialization Initiative, and operated by EG G Rocky Flats in cooperation with the American Welding Society and the Colorado School of Mines Center for Welding and Joining Research. The overall objectives of the workshop were to validate the need for a Joining Technologists to fill the gap between the welding operator and the welding engineer, and to assure that the PJC will train individuals to satisfy that need. The consensus of the workshop participants was that the Joining Technologist is a necessary position in industry, and is currently used, with some variation, by many companies. It was agreed that the PJC core curriculum, as presented, would produce a Joining Technologist of value to industries that use precision joining techniques. The advantage of the PJC would be to train the Joining Technologist much more quickly and more completely. The proposed emphasis of the PJC curriculum on equipment intensive and hands-on training was judged to be essential.

Full Text Available CONTEXT: Young patients affected by acute myeloid leukemia (AML achieve complete remission (CR using conventional chemotherapy in about 55-85%. However, 30% of patients fail to achieve CR and the remission duration is often only about 12 months. More intensive treatment after CR seems to be necessary in order to maintain CR and obtain a definitive cure. In Brazil, few reports have been published on this important subject. OBJECTIVE: The aim of this study was to describe a Brazilian experience in the treatment of "de novo" acute myeloid leukemia (AML in younger adult patients (age < 60 years. DESIGN: Retrospective analysis. SETTING: University Hospital, Hematology and Hemotherapy Center, State University of Campinas, Brazil. PARTICIPANTS: Newly diagnosed cases of "de novo" AML in the period from January 1994 to December 1998 were evaluated retrospectively, in relation to response to treatment, overall survival (OS and disease free survival (DFS. Cases with acute promyelocytic leukemia (APL were also included in this analysis. RESULTS: On the basis of an intention to treat, 78 cases of AML, including 17 cases of APL, were evaluated. The overall median follow-up was 272 days. The complete remission (CR rate was 63.6% in the AML group (excluding APL and 78% in the APL group. The 5-year estimated disease-free survival (DFS was 80% for the APL group and 34% for the AML group (P = 0.02. The 5-year estimated overall survival (OS was 52% for the APL group and 20.5% for the AML group, respectively (P = NS. Relapse was observed in 12/39 (30.7% patients with AML and 1/11 (9% with APL. CONCLUSIONS: These results are similar to those reported in the literature. However, relapse and mortality rates remain high, and a search for more aggressive strategies in order to prevent relapse is recommended.

In 1992, over 165 countries signed the United Nation`s Framework Convention on Climate Change (FCCC). These countries have implicitly agreed to alter their `anthropogenic activities` that increase the emissions of greenhouse gases (GHGs) into the atmosphere and deplete the natural sinks for these same greenhouse gases. The energy sector is the major source of the primary anthropogenic GHGs, notably carbon dioxide and methane. The Organization for Economic Co-operation and Development (OECD) countries presently account for the major share of GHG emissions from the energy sector. However, the developing countries are also rapidly increasing their contribution to global GHG emissions as a result of their growing consumption of fossil-based energy. Implementation of this global climate change convention, if seriously undertaken by the signatory countries, will necessitate changes in the energy mix and production processes in both the OECD and developing countries. International actions also will be needed to put the world on a sustainable energy path. By adoption of the FCCC, representatives of the world`s populations have indicated their desire to move toward such a path. The Conference of Parties to the Convention has just concluded its second meeting, at which the Parties endorsed a U.S. proposal that legally binding and enforceable emissions targets be adopted. It is clearly evident that the FCCC, as presently operating, cannot achieve the objective of stabilizing GHG concentrations in the atmosphere unless it adopts a major protocol to significantly reduce anthropogenic GHG emissions. As demonstrated here, a good starting point in determining the steps the Parties to the FCCC should take in designing a protocol is to remember that the primary source of anthropogenic GHG emissions is the consumption of fossil fuels and the future growth of GHG emissions will derive primarily from the ever-increasing demand for and consumption of these fuels.

To compare the dentofacial effects of mandibular incisor intrusion using mini-implants with those of a conventional incisor intrusion mechanic, the utility arch. Twenty-six deep-bite patients were enrolled to one of the two groups. In group 1 the mandibular incisors were intruded using a 0.16 × 0.22-inch stainless-steel segmental wire connected to two mini-implants. In group 2 the mandibular incisor intrusion was performed using a conventional utility arch. Conventional lateral cephalometric radiographs were taken at pretreatment and at the end of intrusion. Thirty landmarks were identified to measure 23 linear and 20 angular measurements. Intragroup comparisons were made using a paired t-test or a Wilcoxon test. Intergroup comparisons were made using a Student's t-test or a Mann-Whitney U-test. The duration of intrusion was 5 months for group 1 and 4 months for group 2. In the implant group, the mean amount of change was 0.4 mm/mo for the incisor tip and 0.3 mm/mo for the center of resistance, and in the utility arch group, the mean amount of change was 0.25 mm/mo for the incisor tip and 0.2 mm/mo for the center of resistance. The mandibular incisors showed an average protrusion of 7° in the implant group and 8° in the utility arch group. Incisor intrusion that was achieved using an implant-supported segmented archwire was no different than the movement achieved with a conventional intrusion utility arch. The only difference between the two methods was in the molar movement.

Vision perception is ambiguous and visual arts play with these ambiguities. While perceptual ambiguities are resolved with prior constraints, artistic ambiguities are resolved by conventions. Is there a relationship between priors and conventions? This review surveys recent work related to these ambiguities in composition, spatial scale, illumination and color, three-dimensional layout, shape, and movement. While most conventions seem to have their roots in perceptual constraints, those conventions that differ from priors may help us appreciate how visual arts differ from everyday perception.

To evaluate and compare the use of micro-computed tomography (microCT) to investigate the mineral concentration of the treated dentin surface after caries removal with fluorescence-aided caries excavation (FACE) and conventional excavation. 20 extracted human teeth with dentin caries were bisected through the lesion center into two halves which were distributed to a FACE and a conventional excavation group. Tungsten-carbide round burs were used for both groups. Each specimen was investigated with microCT after excavation. The obtained images of all the specimens were evaluated using Image J. Based on the grey values, the linear attenuation coefficients were calculated. Four resin-embedded solid hydroxyapatite phantoms with the gradually increased mineral concentration were used to obtain a calibration curve and equation. Finally, the mineral concentration values of the superficial dentin of each specimen after removal and sound dentin were calculated. The data were compared with the Student's t-test. The statistical results showed that the linear attenuation coefficient (LAC) of the treated surface was significantly lower (P excavation group was 2.98 +/- 0.19 cm(-1). The LAC of sound dentin was 3.89 +/- 0.10 cm(-1). By using the calibration equation, the calculated mineral concentration of the superficial dentin after caries removal were 0.68 +/- 0.14 g/cm3 in the FACE group and 1.05 +/- 0.08 g/cm3 in the conventional excavation group. The mineral concentration of sound dentin was 1.44 +/- 0.04 g/cm3. The mineral concentration of the superficial dentin after caries removal in the FACE group was about 47% of that of sound dentin, while the value in the conventional excavation group was approximately 73% of that of sound dentin. Under the conditions of this in vitro study, the results of the microCT evaluation may imply that FACE was more conservative than conventional excavation.

The main objective of urban drainage system is to allow the safe passage of pedestrians and vehicles quickly evacuating the runoff to prevent flooding. However, development of cities has altered the natural water cycle and providing wide range of contaminants to surface water streams receiving rain from the urban system. For these reasons we have developed unconvention-urban al rainwater systems unconventional rainwater, in accordance with sustainable development, called Sustainable Urban Drainage Systems (SUDS). Considering that the urban drainage system begins with the collection on the site of origin of runoff, in this article the study of conventional and unconventional elements for capturing rainwater arises, establishing the general criteria for selection and design and the classification of SUDS.

Introduction E-cigarette ‘vaping conventions’ provide a venue for user social networking, parties, and ‘try before you buy’ access to a wide range of e-cigarette products. This study identifies and describes vaping conventions, raising awareness of this potentially problematic practice. Methods Conventions were identified via Google searches in April and May 2014 and August 2015. Details captured included location, sponsors, admission cost, event features, and promotions. Results 41 distinct organizations have planned 90 vaping conventions in 37 different locations since 2010. Conventions promoted access to a wide range of product vendors, seminars, social interactions with other users, parties, gifts, vaping contests, and other events. E-cigarette use at conventions was encouraged. Conclusions Vaping conventions promote e-cigarette use and social norms without public health having a voice to educate attendees about negative consequences of use. Future research should focus on the effects of attending these conventions on attendees and on indoor air quality in vapor-filled convention rooms. PMID:26424201

The concept of a heat pump centered integrated community energy system (HP-ICES) was explored based on a reference community located in the Northeast with a population of 10,000. Engineering and economic analyses were performed for the HP-ICES and for conventional heating/cooling systems. Sensitivity analyses were used to determine variations in results from changes in: community size; community energy density; waste heat utilization; energy cost escalation; maintenance and operating personnel; and central HP-ICES ownership. The effect of each of the critical parameters on the economic viability of HP-ICES is shown. Conditions of equal 20-year life cycle costs for HP-ICES and for conventional systems are given. If little or no waste heat is available from nearby industrial installations, high community energy density rates (corresponding to urban conditions) are required for economic viability of HP-ICES. If large amounts of waste heat are available, even relatively loosely built-up communities look promising provided the system is owned by the municipality. If the system is owned and operated by a shareholder-owned public utility, either the community energy density must be high, or large quantities of waste heat must be available, or electricity and oil costs must escalate rapidly during the life of the system to assure economic competitiveness with conventional systems. All HP-ICES use significantly less resource energy than conventional systems. For the baseline system analyzed, HP-ICES use 26% to 40% less resource energy than conventional systems during the heating season and 19% less energy during the peak cooling period. The annual resource energy saving for the HP-ICES is 22% to 34%. It is estimated that the HP-ICES concept is applicable to an average of 500 new communities to be constructed during the 1985--2000 period. The probable resource energy saving during that time period is 1.25 x 10/sup 15/ Btu.

The neural mechanisms underlying the processing of conventional and novel conceptual metaphorical sentences were examined with event-related potentials (ERPs). Conventional metaphors were created based on the Contemporary Theory of Metaphor and were operationally defined as familiar and readily interpretable. Novel metaphors were unfamiliar and harder to interpret. Using a sensicality judgment task, we compared ERPs elicited by the same target word when it was used to end anomalous, novel metaphorical, conventional metaphorical and literal sentences. Amplitudes of the N400 ERP component (320-440 ms) were more negative for anomalous sentences, novel metaphors, and conventional metaphors compared with literal sentences. Within a later window (440-560 ms), ERPs associated with conventional metaphors converged to the same level as literal sentences while the novel metaphors stayed anomalous throughout. The reported results were compatible with models assuming an initial stage for metaphor mappings from one concept to another and that these mappings are cognitively taxing.
Full Text Available Bond markets have not been well developed in emerging countries. Realizing its important role, especially after the 1997 crises and the islamic economics development, emerging countries have started to develop such markets. This research examines the effect of interest rates and currencies on Islamic and conventional bonds in Bursa Malaysia. The analysis on Islamic bonds shows that interest rates and currencies do not influence Islamic bonds, which supports the prohibition of interest in Islam. The analysis on conventional bonds finds evidence that both interest rates and currencies affect conventional bond. It also finds evidence of a negative association between interest rates and a conventional bond.

The popularity of electronic (e-) cigarettes has greatly increased recently, particularly in adolescents. However, the extent of psychiatric comorbidity with adolescent e-cigarette use and dual use of conventional (combustible) and e-cigarettes is unknown. This study characterized psychiatric comorbidity in adolescent conventional and e-cigarette use. Ninth grade students attending high schools in Los Angeles, CA (M age = 14) completed self-report measures of conventional/e-cigarette use, emotional disorders, substance use/problems, and transdiagnostic psychiatric phenotypes consistent with the NIMH-Research Domain Criteria Initiative. Outcomes were compared by lifetime use of: (1) neither conventional nor e-cigarettes (non-use; N = 2557, 77.3%); (2) e-cigarettes only (N = 412, 12.4%); (3) conventional cigarettes only (N = 152, 4.6%); and (4) conventional and e-cigarettes (dual use; N = 189, 5.6%). In comparison to adolescents who used conventional cigarettes only, e-cigarette only users reported lower levels of internalizing syndromes (depression, generalized anxiety, panic, social phobia, and obsessive-compulsive disorder) and transdiagnostic phenotypes (i.e., distress intolerance, anxiety sensitivity, rash action during negative affect). Depression, panic disorder, and anhedonia were higher in e-cigarette only vs. non-users. For several externalizing outcomes (mania, rash action during positive affect, alcohol drug use/abuse) and anhedonia, an ordered pattern was observed, whereby comorbidity was lowest in non-users, moderate in single product users (conventional or e-cigarette), and highest in dual users. These findings: (1) raise question of whether emotionally-healthier ('lower-risk') adolescents who are not interested in conventional cigarettes are being attracted to e-cigarettes; (2) indicate that research, intervention, and policy dedicated to adolescent tobacco-psychiatric comorbidity should distinguish conventional cigarette, e-cigarette, and dual use

Consumers of organically grown fruits and vegetables often believe that these products taste better than conventional produce. However, comparison of produce from supermarket shelves does not permit adequate assessment of this consumer perception, given potentially confounding cultivar and environmental effects. We used replicated side-by-side plots to produce organic and conventional vegetables for consumer sensory studies. In one test, red loose leaf lettuce, spinach, arugula, and mustard greens, grown organically and conventionally, were evaluated for overall liking as well as for intensity of flavor and bitterness. Another consumer test was conducted comparing organically and conventionally grown tomatoes, cucumbers, and onions. Overall, organically and conventionally grown vegetables did not show significant differences in consumer liking or consumer-perceived sensory quality. The only exception was in tomatoes where the conventionally produced tomato was rated as having significantly stronger flavor than the organically produced tomato. However, overall liking was the same for both organic and conventional samples. As conventional tomatoes also were scored marginally significantly higher in ripeness and a positive correlation was found between ratings of flavor intensity and ripeness, the flavor difference observed could not be simply ascribed to the contrasting growing conditions. Consumer panelists in both tests considered organic produce to be healthier (72%) and more environmentally friendly (51%) than conventional produce, while 28% considered organic produce to have better taste. Covariance analysis indicated that consumer demographics affected sensory comparisons of organic and conventional lettuce and cucumbers. Future study is needed to substantiate the influence of segmentation of consumers on their preference for organic food.
For NASA's Resource Prospector (RP) Lunar Rover Mission, we are moving away from a control center concept, to a fully distributed operation utilizing control nodes, with decision support from anywhere via mobile devices. This operations concept will utilize distributed information systems, notifications, mobile data access, and optimized mobile data display for off-console decision support. We see this concept of operations as a step in the evolution of mission operations from a central control center concept to a mission operations anywhere concept. The RP example is part of a trend, in which mission expertise for design, development and operations is distributed across countries and across the globe. Future spacecraft operations will be most cost efficient and flexible by following this distributed expertise, enabling operations from anywhere. For the RP mission we arrived at the decision to utilize a fully distributed operations team, where everyone operates from their home institution, based on evaluating the following factors: the requirement for physical proximity for near-real time command and control decisions; the cost of distributed control nodes vs. a centralized control center; the impact on training and mission preparation of flying the team to a central location. Physical proximity for operational decisions is seldom required, though certain categories of decisions, such as launch abort, or close coordination for mission or safety-critical near-real-time command and control decisions may benefit from co-location. The cost of facilities and operational infrastructure has not been found to be a driving factor for location in our studies. Mission training and preparation benefit from having all operators train and operate from home institutions.

Information technology (IT) is becoming increasingly pervasive throughout society as more data is digitally processed, stored, and transferred. The infrastructure that supports IT activity is growing accordingly, and data center energy demands haveincreased by nearly a factor of four over the past decade. Data centers house IT equipment and require significantly more energy to operate per unit floor area thanconventional buildings. The economic and environmental ramifications of continued data center growth motivate the need to explore energy-efficient methods to operate these buildings. A substantial portion of data center energy use is dedicated to removing the heat that is generated by the IT equipment. Using economizers to introduce large airflow rates of outside air during favorable weather could substantially reduce the energy consumption of data center cooling. Cooling buildings with economizers is an established energy saving measure, but in data centers this strategy is not widely used, partly owing to concerns that the large airflow rates would lead to increased indoor levels of airborne particles, which could damage IT equipment. The environmental conditions typical of data centers and the associated potential for equipment failure, however, are not well characterized. This barrier to economizer implementation illustrates the general relationship between energy use and indoor air quality in building design and operation. This dissertation investigates how building design and operation influence energy use and indoor air quality in data centers and provides strategies to improve both design goals simultaneously.As an initial step toward understanding data center air quality, measurements of particle concentrations were made at multiple operating northern California data centers. Ratios of measured particle concentrations in conventional data centers to the corresponding outside concentrations were significantly lower than those reported in the literature

The aim of this trial was to compare the rates of patency achieved by cutting and conventional balloon angioplasty to treat hemodialysis access stenoses. End-stage renal failure patients (at three tertiary referral centers) with significant hemodialysis access stenoses were prospectively randomized to have percutaneous transluminal angioplasty (PTA) by either cutting or conventional balloons. Patients with more than one hemodynamically significant stenosis were excluded. Kaplan-Meier method was used to compare the primary assisted patency rates for the two groups. The study randomized 623 patients into two groups, and the duration of follow-up was 15 ± 3 months. In the cutting balloon angioplasty group, the clinical success rate was 89% (282 of 316 stenoses). In the conventional balloon angioplasty group, the clinical success rate was 86% (265 of 307 stenoses; P = .637). Assisted primary patency for cutting PTA was statistically significantly higher at 6 months and 1 year (86% and 63%) than that for conventional PTA (56% and 37%, respectively; P = .037) in the treatment of stenosis of the graft-to-vein anastomosis. In the venous stenosis subgroup, equivalent primary assisted patency at 6 months and 1 year was observed for cutting PTA (84% and 55%) and conventional PTA (70% and 46%, respectively; P = .360). In the intragraft stenosis subgroup, primary assisted patency was equivalent at 6 months and 1 year for cutting PTA (67% and 39%) and conventional PTA (62% and 49%, respectively; P = .371). In the arterial anastomotic stenosis subgroup, assisted primary patency at 6 months and 1 year was equivalent for cutting PTA (70% and 30%) and conventional PTA (75% and 33%, respectively; P = .921). Cutting balloon angioplasty proved to be a safe and effective treatment of graft-to-vein anastomotic stenosis, with significantly higher patency than that of conventional balloon angioplasty.

The mission of the Sustainable Bioenergy Development Center (SBDC) is to enhance the capability of America’s bioenergy industry to produce transportation fuels and chemical feedstocks on a large scale, with significant energy yields, at competitive cost, through sustainable production techniques. Research within the SBDC is organized in five areas: (1) Development of Sustainable Crops and Agricultural Strategies, (2) Improvement of Biomass Processing Technologies, (3) Biofuel Characterization and Engine Adaptation, (4) Production of Byproducts for Sustainable Biorefining, and (5) Sustainability Assessment, including evaluation of the ecosystem/climate change implication of center research and evaluation of the policy implications of widespread production and utilization of bioenergy. The overall goal of this project is to develop new sustainable bioenergy-related technologies. To achieve that goal, three specific activities were supported with DOE funds: bioenergy-related research initiation projects, bioenergy research and education via support of undergraduate and graduate students, and Research Support Activities (equipment purchases, travel to attend bioenergy conferences, and seminars). Numerous research findings in diverse fields related to bioenergy were produced from these activities and are summarized in this report.

Twenthy-three children with Legg-Calve-Perthes disease were examined to determine the femoral head shape. We evaluated and correlated conventional radiography, arthrography and MR imaging. In the a.p. view, measurements were obtained from the center of the femoral head along the bony or cartilaginous outline at 30 intervals. Maximum flattening of the cartilaginous outline appeared laterally, 60 from the center of the baseline of the epiphyseal index and the caput index. Maximum flattening of the bony outline was found at 75 . Arthrography and MR imaging gave the same information about the shape of the femoral head cartilage. The bony femoral head shape on conventional radiographs in the a.p. view did not reflect the cartilage shape obtained by MR and arthrography. (orig.).

The objective of this study was to describe and compare husbandry practices on organic and conventional dairy farms of similar sizes in Minnesota. Organic (ORG, n=35), same-sized conventional (SC, n=15, conventional (MC, n=13, ≥200 cows) dairy herds were visited in 2012, and farmers were interviewed once about their farm, herd demographics, and herd management practices concerning nutrition, housing, and reproductive programs. Organic farms had been established as long as conventional farms, and ORG producers had most commonly selected ORG farming because of a negative perception of pesticides for human health. The distribution of cattle breeds and ages differed across farm types. Organic farms had more crossbred cows and a greater number of older cows than conventional farms, who had mainly Holstein cattle. Organic farms did not dock tails, were more likely to use breeding bulls, and were less likely to conduct pregnancy diagnoses in cattle. All conventional farmers fed corn, corn silage, and hay, but no forage or feed supplement was fed by all ORG farms with the exception of pasture. Kelp was supplemented on most ORG farms but on none of the conventional farms. In summary, although there were differences across farm types regarding the use of pasture, feeds, and feed additives, breed and age distribution, reproductive management, and the use of tail docking, observations in other management areas showed large overlap across herd types.

The Chemical Weapons Convention (CWC) is an unprecedented multilateral effort to eradicate an entire category of weapons of mass destruction and assure their continued absence through international verification. In 1993, concerns arose that the complexity of integrating the treaty with national law could cause some nations to implement the Convention without regard to what others nations were doing, thereby causing inconsistencies among States Parties in how the Conventional would be carried out. As a result, the Manual for National Implementation of the Chemical Weapons Convention was prepared. The Manual is designed to assist States Parties by increasing understanding of the Convention and identifying its obligations as well as suggesting methods to meet them, duly taking into account the distinctive aspects of their legal systems. It acknowledges areas of ambiguity that States Parties should address, and it analyzes legal initiatives that may be undertaken to strengthen the Convention`s enforcement. This paper draws from the Manual and briefly addresses the two tasks that every CWC State Party must undertake first in order to effectively fulfill its extensive requirements. First, each State Party must establish a National Authority. Second, each State Party must enact implementing measures to ensure that its government as well as its businesses and citizens comply with the treaty. As this paper generally discusses how States Parties from different legal backgrounds can accomplish these two tasks, it cannot address every detail of how each State Party should proceed.

The tomato and lettuce datasets suggest that the different types of fertilizer commonly used in organic and conventional systems result in differences in the nitrogen isotope composition of these crops. A mean delta15N value of 8.1 per thousand was found for the organically grown tomatoes compared with a mean value of -0.1 per thousand for those grown conventionally. The organically grown lettuces had a mean value of 7.6 per thousand compared with a mean value of 2.9 per thousand for the conventionally grown lettuces. The mean value for organic carrots was not significantly different from the mean value for those grown conventionally. Overlap between the delta15N values of the organic and conventional datasets (for both tomatoes and lettuces) means that it is necessary to employ a statistical methodology to try and classify a randomly analyzed "off the shelf" sample as organic/conventional, and such an approach is demonstrated. Overall, the study suggests that nitrogen isotope analysis could be used to provide useful "intelligence" to help detect the substitution of certain organic crop types with their conventional counterparts. However, delta15N analysis of a "test sample" will not provide unequivocal evidence as to whether synthetic fertilizers have been used on the crop but could, for example, in a situation when there is suspicion that mislabeling of conventionally grown crops as "organic" is occurring, be used to provide supporting evidence.

With the development of big data and information globalization, the requirements of massive information transmitting and sharing among data centers are expanding, especially among those data centers which are extremely far away from each other. In the above field, conventional optical fiber transmission faces many problems such as complex networking, poor security, long node switching delay, high lease and maintain cost and low migration flexibility. Besides, in the near future, data centers may tend to be built in the remote Polar Regions or on the sea for natural cooling. For the above situation, sharing the massive information among global data centers based on satellite laser communication is proposed in this paper. This proposal includes advantage analysis, research of restraining atmosphere interference, etc. At last, by comparison with conventional technology, the research result shows that massive information transmitting and sharing among global data centers based on satellite laser communication has far reaching application potential.
Full Text Available This paper shows the study of preswirl duct as an effective energy saving devices that have been devised and reviewed to support the propeller performance, especially for the ship of VLCC with large block coefficients. From the bare hull wake measurements, typical upper/lower asymmetry of hull wake at the propeller disk was found. The 2 kinds of pre-swirl duct, Unconventional half circular duct and Conventional circular pre-swirl duct have been designed and reviewed to recover the loss of propeller running in that condition. The general function of the pre-swirl duct was set to work against this asymmetry of wake and generate pre-swirled flow into the propeller against the propeller ro-tating direction. The optimum self propulsion tests with various angle configurations were carried out and the best configuration was decided. Accordingly, cavitation test was carried out with best configuration of unconventional half circular duct. The blade surface and tip vortex cavitation behaved smoother when the duct was mounted. The hull pressure amplitudes reflected this difference, so the hull pressure amplitude with duct was smaller than that of without duct.

To improve the choice of vacuum-assisted delivery (VAD) system, we compared the outcomes of Kiwi handheld system and Mityvac M-style conventional system (both use disposable plastic cups). Retrospective observational study with data collection from electronic medical records. The study was conducted at a tertiary medical center, with approximately 7000 deliveries annually. Categorical and continuous variables were analyzed using chi-square test and t-test, respectively. p value Kiwi-assisted and 143 Mityvac-assisted. Background characteristics were similar. The handheld system had more failures overall (9.6 versus 0.7%), at OA (7.6 versus 0.9%), and non-OA positions (17.3% versus none), at +1 (13.25 versus 0.96%) and at +2/3 stations (6.1% versus none), than the conventional system did, respectively. There was a higher rate of early post-partum hemorrhage (15.3 versus 7.4%) in the conventional group. Both systems had similar rates of third/fourth degree perineal tears, shoulder dystocia and adverse neonatal outcomes. Our results suggest more failures with Kiwi compared to Mityvac, overall and at any fetal position/station, without a significant difference in adverse outcome profile.

Objectives: To retrospectively evaluate the diagnostic performance of morphological signs observed on conventional magnetic resonance (MR) imaging to differentiate benign from malignant peripheral solid tumors of soft tissue with myxoid stroma. Methods: MR images from 95 consecutive histopathologically proven tumors (26 benign and 69 malignant) of soft tissues with myxoid components were evaluated in our tertiary referral center. Two radiologists, blind to pathology results, independently reviewed conventional MR sequences including at least a) one T2-weighted sequence with or without fat suppression; b) one T1-weighted sequence without fat suppression; and c) one T1-weighted sequence with gadolinium-complex contrast enhancement and fat suppression. Multiple criteria were defined to analyze morphology, margins, architecture and tumor periphery and evaluated for each lesion. Intra- and inter-observer reproducibility and Odds ratios were calculated for each criterion. Results: The most relevant and reproducible criteria to significantly predict malignancy were: (1) ill-defined tumor margins, (2) a hemorrhagic component, (3) intra-tumoral fat, (4) fibrosis and (5) the “tail sign”. A lesion is classified as malignant if any of these 5 criteria is present, and benign if none of them are observed. Therefore, this combination provides a sensitivity of 92.9% and a specificity of 93.3%. Conclusion: Conventional MR imaging provides reproducible criteria that can be combined to differentiate between benign and malignant solid tumors of soft tissue with myxoid stroma.

The co-existence approach of GM crops with conventional agriculture and organic farming as a feasible agricultural farming system has recently been placed in the center of hot debates at the EU-level and become a source of anxiety in developing countries. The main promises of this approach is to ensure "food security" and "food safety" on the one hand, and to avoid the adventitious presence of GM crops in conventional and organic farming on the other, as well as to present concerns in many debates on implementing the approach in developing countries. Here, we discuss the main debates on ("what," "why," "who," "where," "which," and "how") applying this approach in developing countries and review the main considerations and tradeoffs in this regard. The paper concludes that a peaceful co-existence between GM, conventional, and organic farming is not easy but is still possible. The goal should be to implement rules that are well-established proportionately, efficiently and cost-effectively, using crop-case, farming system-based and should be biodiversity-focused ending up with "codes of good agricultural practice" for co-existence.

Patients and methods: Experienced eyedrop users were enrolled who answered “yes” to the question, “Do you ever have trouble getting your eyedrops in?” After being shown a multimedia presentation and answering a questionnaire regarding eyedrop usage, participants were observed instilling eyedrops. Participants were instructed to instill a single eyedrop in each eye with both a standard bottle and the UEB. They repeated this process three times. With each trial, the amount of time taken to instill drops was recorded, as well as whether a drop landed in the eye (accuracy, if excess drops were used, and if the bottle tip was contaminated. Results: Forty participants were enrolled, with an average age of 72.4±8.9 years; the majority were females (24 females. Thirty-four participants had been using eyedrops for at least 1 year. The time required to instill eyedrops was significantly less with the UEB in the second and third trials. There was no difference in accuracy between the conventional bottle and the UEB
Computational Science is an integral component of Brookhaven's multi science mission, and is a reflection of the increased role of computation across all of science. Brookhaven currently has major efforts in data storage and analysis for the Relativistic Heavy Ion Collider (RHIC) and the ATLAS detector at CERN, and in quantum chromodynamics. The Laboratory is host for the QCDOC machines (quantum chromodynamics on a chip), 10 teraflop/s computers which boast 12,288 processors each. There are two here, one for the Riken/BNL Research Center and the other supported by DOE for the US Lattice Gauge Community and other scientific users. A 100 teraflop/s supercomputer will be installed at Brookhaven in the coming year, managed jointly by Brookhaven and Stony Brook, and funded by a grant from New York State. This machine will be used for computational science across Brookhaven's entire research program, and also by researchers at Stony Brook and across New York State. With Stony Brook, Brookhaven has formed the New York Center for Computational Science (NYCCS) as a focal point for interdisciplinary computational science, which is closely linked to Brookhaven's Computational Science Center (CSC). The CSC has established a strong program in computational science, with an emphasis on nanoscale electronic structure and molecular dynamics, accelerator design, computational fluid dynamics, medical imaging, parallel computing and numerical algorithms. We have been an active participant in DOES SciDAC program (Scientific Discovery through Advanced Computing). We are also planning a major expansion in computational biology in keeping with Laboratory initiatives. Additional laboratory initiatives with a dependence on a high level of computation include the development of hydrodynamics models for the interpretation of RHIC data, computational models for the atmospheric transport of aerosols, and models for combustion and for energy utilization.

Over the five-year period (2002-2006) the Oklahoma State University Industrial Assessment Center (IAC) performed energy assessments for 106 different clients, writing 835 recommendations, for a total of $23,937,099 in potential estimated annual savings. IAC clients served consisted of small and medium-sized manufacturers ranging from food manufactures to foundries. The OSU IAC served clients in Oklahoma, Kansas, Missouri, Arkansas, and Texas. In addition to client service, student training and instruction was a major accomplishment. The OSU IAC employed (and trained) 12 baccalaureate-level students, 17 masters-level graduate students, and 7 doctoral-level graduate students. Most are practicing in the energy management area. Training was focused on both energy assessment and safety. Safety training was both center-based training as well as on-site training. Energy management related training was focused on classroom (for academic credit) work at both the undergraduate and graduate level. IEM 4923 (Energy and Water Management) was developed to serve both the IAC as well as non-IAC students. It was delivered once per year, with enrollments of typically 10 to 20 students. This course was required for IAC student employees, both undergraduate and graduate. This course was patterned after the AEE CEM (five-day) course for practicing professionals. IEM 4923 required each student to attend at least one on-site assessment and write at least one recommendation for their client’s report. Hence, a hands-on approach was practiced. Advance level courses were used to train graduate students. Two courses played major roles here: IEM 5923 (Advanced Energy and Water Management) and IEM 5943 (Hazardous Material and Waste). Graduate student participation in these courses helped the IAC to gain additional perspectives in on-site assessment and resulting recommendations. Numerous hands-on demonstration/training was conducted by directors and graduate students in order to gain

The Supernova Science Center (SNSC) was founded in 2001 to carry out theoretical and computational research leading to a better understanding of supernovae and related transients. The SNSC, a four-institutional collaboration, included scientists from LANL, LLNL, the University of Arizona (UA), and the University of California at Santa Cruz (UCSC). Intitially, the SNSC was funded for three years of operation, but in 2004 an opportunity was provided to submit a renewal proposal for two years. That proposal was funded and subsequently, at UCSC, a one year no-cost extension was granted. The total operational time of the SNSC was thus July 15, 2001 - July 15, 2007. This document summarizes the research and findings of the SNSC and provides a cummulative publication list.
Full Text Available Today architecture has to design for rapidly changing futures, in a citizen-centered way. That is, architecture needs to embrace meaningful design. Societal challenges ask for a new paradigm in city-making, which combines top-down public management with bottom-up social innovation to reach meaningful design. The biggest challenge is indeed to embrace a new collaborative attitude, a participatory approach, and to have the proper infrastructure that supports this social fabric. Participatory design and transition management are future-oriented, address people and institutions. Only through understanding people in context and the corresponding dynamics, one is able to design for liveable and sustainable urban environments, embracing the human scale.

"The Center is Everywhere" is a sculpture by Josiah McElheny, currently (through October 14, 2012) on exhibit at the Institute of Contemporary Art, Boston. The sculpture is based on data from the Sloan Digital Sky Survey (SDSS), using hundreds of glass crystals and lamps suspended from brass rods to represent the three-dimensional structure mapped by the SDSS through one of its 2000+ spectroscopic plugplates. This article describes the scientific ideas behind this sculpture, emphasizing the principle of the statistical homogeneity of cosmic structure in the presence of local complexity. The title of the sculpture is inspired by the work of the French revolutionary Louis Auguste Blanqui, whose 1872 book "Eternity Through The Stars: An Astronomical Hypothesis" was the first to raise the spectre of the infinite replicas expected in an infinite, statistically homogeneous universe. Puzzles of infinities, probabilities, and replicas continue to haunt modern fiction and contemporary discussions of inflationary cosmo...

To compare the clinical efficacy of computer-assisted pedicle screw placement and conventional placement in the treatment of spinal disease. A systematic search of studies published between Jan. 1990 and Feb. 2012 was conducted using Medline, Embase, OVID, ScienceDirect and Cochrane Review databases. Randomized controlled trials (RCTs) and prospective controlled trials of comparing computer-assisted pedicle screw placement to conventional method performed at one center or multi-centers providing data on accuracy of placement and clinical effects were identified. Two study authors independently reviewed the 93 articles originally identified and selected 10 for analysis. Study title,demographic characteristics,number of pedicle screw,anatomical area and outcomes were extracted manually from all selected studies. RevMan 5.1 software was used for meta-analysis. Ten studies encompassing 2813 pedicle screws met the inclusion criteria. Overall,the result of meta-analysis indicated that there were significant differences between two groups in accuracy in placement of pedicle screw [OR = 2.58, 95% CI (1.18, 5.63)], insertion time [WMD = -2.15, 95% CI (-2.36, -1.94)]. However, there was only one study reported preparation time of pedicle screw of navigation group was longer than conventional group. No neurological complication in navigation group was reported. As a safety supplementary measure, computer navigation provide better accuracy in placement of pedicle screw and insertion time. The preparation time of pedicle screw may prolong due to the complexity of navigation system. Further reseach should include randomized controlled trials with well-planned methodology to limit bias.

Organic agricultural systems are often assumed to be more sustainable than conventional farming, yet there has been little work comparing surface water quality from organic and conventional production, especially under the same cropping sequence. Our objective was to compare nutrient and sediment losses, as well as sweet corn ( L. var. ) yield, from organic and conventional production with conventional and conservation tillage. The experiment was located in the Appalachian Mountains of North Carolina. Four treatments, replicated four times, had been in place for over 18 yr and consisted of conventional tillage (chisel plow and disk) with conventional production (CT/Conven), conservation no-till with conventional production (NT/Conven), conventional tillage with organic production (CT/Org), and conservation no-till with organic production (NT/Org). Water quality (surface flow volume; nitrogen, phosphorus, and sediment concentrations) and sweet corn yield data were collected in 2011 and 2012. Sediment and sediment-attached nutrient losses were influenced by tillage and cropping system in 2011, due to higher rainfall, and tillage in 2012. Soluble nutrients were affected by the nutrient source and rate, which are a function of the cropping system. Sweet corn marketable yields were greater in conventional systems due to high weed competition and reduced total nitrogen availability in organic treatments. When comparing treatment efficiency (yield kg ha /nutrient loss kg ha ), the NT/Conven treatment had the greatest sweet corn yield per unit of nutrient and sediment loss. Other treatment ratios were similar to each other; thus, it appears the most sustainably productive treatment was NT/Conven.

Full Text Available The term “organic” denotes a product of a food production system that is socially, ecologically, and economically sustainable. The organic food market is growing in response to an ever increasing demand for organic products. They are often considered more nutritious, healthier, and free from pesticides than conventional foods. However, the results of scientific studies do not show that organic products are more nutritious and safer than conventional foods. In this work a comparison between conventional and organic foods is made, the focus is on animal products. The data available in the existing literature is often conflicting, even if the differences are often associated with breeds suited to organic vs. conventional production systems. In order to have a clear understanding of the role that “organic effect” plays on animal foods, further research is necessary.

Rice fields are temporary wetlands prone to contamination from agricultural chemicals which affect their ecotoxicology and benthic community composition. The diversity of benthic fauna in both organic and conventional rice fields in Kalasin Province, Thailand was investigated. Benthos samples were collected by grab sampling from 20 stations in organic and conventional rice fields during one successive crop in August 2014. The number of benthic organisms found at each sampling station ranged from 16-518 and 24-137 individuals for organic and conventional rice fields, respectively. The benthic fauna in organic rice fields were dominated by crustaceans 41%, insects 31%, annelids 26%, and gastropods 2%. The conventional rice fields benthic fauna was composed of insects 51%, annelids 41%, and gastropods 8%. The abundance and composition of the benthic fauna demonstrated that organic rice farming practices are beneficial to sustaining the biodiversity in rice field ecosystems.

The possibilities and limitations of conventional radiography and CT in detecting maxillo-facial fractures are shown both experimentally and in a clinical setting. In 36 patients examined by both methods after maxillo-facial trauma, CT and conventional radiography (including pluridirectional tomography) proved to be equal in detecting fractures of the orbital roof, the anterior wall of the frontal sinus, the nasal bone and the pterygoid process. CT is inferior to conventional radiography in fractures of the orbital floor, the frontal base of the skull, the hard plate and the zygomatic arch. CT is superior to conventional radiography in fractures of the medial and lateral wall of the orbit, the posterior wall of the frontal sinus, the posterior, medial and anterior wall of the maxillary sinus as well as the zygomatic bone.

To evaluate the efficacy of autologous conditioned plasma (ACP) compared with extracorporeal shockwave (ESWT) and conventional treatments for plantar fasciitis. Randomized trial. Sports medicine center in a tertiary care hospital. Fifty-four subjects (age range, 29-71 years) with unilateral chronic plantar fasciitis with more than 4 months of symptoms. Subjects randomized to 3 groups: 19 to ACP and conventional treatment (ACP group), 19 to ESWT and conventional treatment (ESWT group), and 16 to conventional treatment alone. Conventional treatment included stretching exercises and orthotics if indicated. Outcomes were pain-Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, and ultrasound plantar fascia thickness assessed at baseline before treatment and at 1 month, 3 months, and 6 months after treatment. VAS, AOFAS ankle-hindfoot scale, and plantar fascia thickness improved in all groups. Significant VAS pain score improvements in the ACP group compared with conventional treatment at month 1 (P = .037) and for the ESWT group compared with conventional treatment at months 1, 3, and 6 (P = .017, P = .022, and P = .042). The AOFAS ankle-hindfoot scale score improved in the ACP group at months 3 and 6 (P = .004 and P = .013) and, for the ESWT group, at months 1 and 3 (P = .011 and P = .003) compared with conventional treatment. Significant improvements in plantar fascia thickness were seen in the ACP group at months 1 and 3 compared with conventional treatments (P = .015 and P = .014) and at months 3 and 6 compared with the ESWT group (P = .019 and P = .027). No adverse events reported. Treatment of plantar fasciitis with ACP or ESWT plus conventional treatments resulted in improved pain and functional outcomes compared with conventional treatment alone. There was no significant difference between ACP and ESWT in terms of VAS and AOFAS ankle-hindfoot scale improvements, although the ACP group demonstrated greater

The term “organic” denotes a product of a food production system that is socially, ecologically, and economically sustainable. The organic food market is growing in response to an ever increasing demand for organic products. They are often considered more nutritious, healthier, and free from pesticides than conventional foods. However, the results of scientific studies do not show that organic products are more nutritious and safer than conventional foods. In this work a comparison between co...

Raw organic and conventional cow’s milk samples were analyzed for total nitrogen, non-protein nitrogen and milk urea content with the aim of evaluation of the different diets effect. Conventional milk contained higher level of total milk urea nitrogen as well as higher proportion in total nitrogen and non-protein nitrogen fraction. We detected that ratio of milk urea nitrogen to non-protein nitrogen is the most significant criterion for assessment of diet differences.

The numerous reforms to the Convention system of the past two decades have unquestionably had an effect on applicants’ means to access justice in the system. It is, however, open to question how these changes should be evaluated: with reference to the individual right to petition, or with reference to a more substantive and general conception of access to justice. This article explores these two approaches to the notion of access to justice both generally and for the Convention system specifi...

Liver slices were cooked with a mixture of cottonseed oil and margarine using microwave oven and gas cooker. The acid values, peroxide numbers, total sterols and fatty acid profiles of unheated and cooked liver slices conventionally and by microwaves were determined. The time required for cooking liver slices by microwaves was one-half of the time required conventionally. Heating the lipid mixture by both heating methods caused highly significant decrease in the acid value. Conversely, the ac...
Magnetic geared actuators (MGA) are designed to perform highly reliable, robust and precise motion on satellite platforms or aerospace vehicles. The design allows MGA to be used for various tasks in space applications. In contrast to conventional geared drives, the contact and lubrication free force transmitting elements lead to a considerable lifetime and range extension of drive systems. This paper describes the fundamentals of magnetic wobbling gears (MWG) and the deduced inherent characteristics, and compares conventional and magnetic gearing.

To conduct a systematic review to evaluate the evidence of possible benefits and accuracy of digital impression techniques vs. conventional impression techniques. Reports of digital impression techniques versus conventional impression techniques were systematically searched for in the following databases: Cochrane Central Register of Controlled Trials, PubMed, and Web of Science. A combination of controlled vocabulary, free-text words, and well-defined inclusion and exclusion criteria guided the search. Digital impression accuracy is at the same level as conventional impression methods in fabrication of crowns and short fixed dental prostheses (FDPs). For fabrication of implant-supported crowns and FDPs, digital impression accuracy is clinically acceptable. In full-arch impressions, conventional impression methods resulted in better accuracy compared to digital impressions. Digital impression techniques are a clinically acceptable alternative to conventional impression methods in fabrication of crowns and short FDPs. For fabrication of implant-supported crowns and FDPs, digital impression systems also result in clinically acceptable fit. Digital impression techniques are faster and can shorten the operation time. Based on this study, the conventional impression technique is still recommended for full-arch impressions. © 2016 by the American College of Prosthodontists.

Full Text Available The goal of the scientific research was to establish the differences between fatty acid composition in conventional milk and milk produced according to the organic production principles. In the period between February and December in 2009, the samples of raw conventional milk were analysed using the gas chromographic method to determine the fatty acid composition. Conventional milk was produced at the farm with around 700 dairy cows of Holstein breed. The farm is located in the Vrbas municipality. Organic milk was sampled from ten smaller farms with 12 dairy cows of Simmental breed on the average, located in clean environment of Fruška Gora slopes (Grabovo settlement. The results of fatty acids content were processed with the statistical package (Statistica 9, and a significant differences were determined with t-test and shown as statistically significant (p0.05. The ratio of omega-6 to omega-3 in organic milk was lower than in conventional milk, which is crucial to human health. The differences in fatty acid composition between conventional and organic milk may result from different feeding practices, because the organic breeding of cows is primarily based on grazing, while the conventional breeding implies mixed ration.
Full Text Available The most important recent policy initiative concerning quality and diversity, as well as natural and cultural landscape's values within all Europe is European Landscape Convention. The Convention was adopted by Council of Europe's Community of Ministers on 20th October 2000., in Firenze, Italy. The main goal of the Convention is protection, planning and management of the landscape as important part of the quality of life for people living everywhere: in urban areas and in countryside, in degraded areas as well as in the areas with high quality and those recognized as being of outstanding beauty. Serbia has singed Convention on 21 of September 2007. Diversity and quality, the cultural and natural values linked to European landscapes are part of Europe's common heritage, and it is important to co-operate towards its protection, management and planning According to explored international experiences, landscape plan, with its known methodology, is recognized as the most suitable tool in the most Countries which have already implemented European Landscape Convention. As to situation in Serbia, landscape planning is not treated in adequate or appropriate way within system of spatial planning. On the basis of the recent European experiences regarding The European Landscape Convention, the paper will underline the inevitability of landscape planning integration into the spatial planning system at the national, regional and city level, in Serbia.

To compare the diagnostic accuracy of hand-held point-of-care (POC) versus conventional sonography in a general diagnostic setting with the intention to inform medical providers or clinicians on the rational use of POC ultrasound in resource limited settings. Over 3 months in 2010, 47 patients were prospectively enrolled at a single academic center to obtain 54 clinical conventional ultrasound examinations and 54 study-only POC ultrasound examinations. Indications were 48% abdominal, 26% retroperitoneal, and 24% obstetrical. Nine blinded readers (sonographers, residents, and attending radiologists) sequentially assigned diagnoses to POC and then conventional studies, yielding 476 interpreted study pairs. Diagnostic accuracy was obtained by comparing POC and conventional diagnoses to a reference diagnosis established by the unblinded, senior author. Analysis was stratified by study type, body mass index (BMI), diagnostic confidence, and image quality. The mean diagnostic accuracy of conventional sonography was 84% compared with 74% for POC (P reader, exam type, or BMI. The sensitivity and specificity to detect abnormalities with conventional was 85 and 83%, compared with 75 and 68% for POC. The POC sonography demonstrated greater variability in image quality and diagnostic confidence, and this accounted for lower diagnostic accuracy. When image quality and diagnostic confidence were similar between POC and conventional examinations, there was no difference in accuracy. Point-of-care was nearly as accurate as conventional sonography for basic, focused examinations. Observed differences in accuracy were attributed to greater variation in POC image quality. © 2017 by the American Institute of Ultrasound in Medicine.

Among 2011's many accomplishments, we safely retired the Space Shuttle Program after 30 incredible years; completed the International Space Station and are taking steps to enable it to reach its full potential as a multi-purpose laboratory; and helped to expand scientific knowledge with missions like Aquarius, GRAIL, and the Mars Science Laboratory. Responding to national budget challenges, we are prioritizing critical capabilities and divesting ourselves of assets no longer needed for NASA's future exploration programs. Since these facilities do not have to be maintained or demolished, the government saves money. At the same time, our commercial partners save money because they do not have to build new facilities. It is a win-win for everyone. Moving forward, 2012 will be even more historically significant as we celebrate the 50th Anniversary of Kennedy Space Center. In the coming year, KSC will facilitate commercial transportation to low-Earth orbit and support the evolution of the Space Launch System and Orion crew vehicle as they ready for exploration missions, which will shape how human beings view the universe. While NASA's Vision is to lead scientific and technological advances in aeronautics and space for a Nation on the frontier of discovery KSC's vision is to be the world's preeminent launch complex for government and commercial space access, enabling the world to explore and work in space. KSC's Mission is to safely manage, develop, integrate, and sustain space systems through partnerships that enable innovative, diverse access to space and inspires the Nation's future explorers.

Previously there was no available information on the levels of indicator bacteria and the prevalence of pathogens in fresh lettuce grown in organic and conventional farms in Spain. A total of 72 lettuce samples (18 farms for 4 repetitions each) for each type of the agriculture were examined in order to assess the bacteriological quality of the lettuces, in particular the prevalence of selected pathogens. The lettuce samples were analyzed for the presence of aerobic mesophilic, psychrotrophic microorganisms, yeasts and moulds, Enterobacteriaceae, mesophilic lactic acid bacteria, Pseudomonas spp. and presumptive Escherichia coli, Salmonella spp. and Listeria monocytogenes. The mean aerobic mesophilic counts (AM) were 6.35 +/- 0.69 log(10) cfu g(-1) and 5.67 +/- 0.80 log(10) cfu g(-1) from organic and conventional lettuce, respectively. The mean counts of psychrotrophic microorganisms were 5.82 +/- 1.01 log(10) cfu g(-1) and 5.41 +/- 0.92 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Yeasts and moulds (YM) mean counts were 4.74 +/- 0.83 log(10) cfu g(-1) and 4.21 +/- 0.96 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Lactic acid bacteria (LAB) were present in low numbers and the mean counts were 2.41 +/- 1.10 log(10) cfu g(-1) and 1.99 +/- 0.91 log(10) cfu g(-1) from organic and conventional lettuce, respectively. Pseudomonas spp. mean counts were 5.49 +/- 1.37 log(10) cfu g(-1) and 4.98 +/- 1.26 log(10) cfu g(-1) in organic and conventional lettuce, respectively. The mean counts for Enterobacteriaceae were 5.16 +/- 1.01 log(10) cfu g(-1) and 3.80 +/- 1.53 log(10) cfu g(-1) in organic and conventional lettuce, respectively. E. coli was detected in 22.2% (16 samples) of organic lettuce and in 12.5% (9 samples) of conventional lettuce. None of the lettuce samples was positive for E. coli O157:H7, L. monocytogenes and Salmonella spp. From the samples analyzed by principal component analysis (PCA) a pattern with two

Full Text Available According to Garcia Canclini (1990 there is the assumption that Colombia is a hybrid society. Upon this standpoint, and within a traditional higher education structure characterized by being fundamentally conventional or campus based, the Open University Center of the Pontificia Universidad Javeriana was created as an education program that breaks with every traditional scheme, which in turn, encourages a new learning pattern. The Open University Center emerges as a "social response" focused on the "here and now" of today's society in Colombia.The Javeriana University (a hybrid university can be placed in this context as well as the Open University Center, as a part of it. Since its creation, through its programs this center offers education to the most vulnerable of Colombia's population, contributing to raise their quality of life.In this article, the authors outline the Open University Center's place in the University's context: its historical development and its structure concerning students, programs, regulations, infrastructure and technological equipment. They also identify the implications and relationships of the traditional education proper of the Pontificia Universidad Javeriana, as well as the projection and contributions of the Open University Center to the University's future in the pedagogical order of distance education towards virtual education.

This report provides a summary of the Smithsonian Astrophysical Observatory (SAO) ROSAT SCIENCE DATA CENTER (RSDC) activities for the recent years of our contract. Details have already been reported in the monthly reports. The SAO was responsible for the High Resolution Imager (HRI) detector on ROSAT. We also provided and supported the HRI standard analysis software used in the pipeline processing (SASS). Working with our colleagues at the Max Planck in Garching Germany (MPE), we fixed bugs and provided enhancements. The last major effort in this area was the port from VMS/VAX to VMS/ALPHA architecture. In 1998, a timing bug was found in the HRI standard processing system which degraded the positional accuracy because events accessed incorrect aspect solutions. The bug was fixed and we developed off-line correction routines and provided them to the community. The Post Reduction Off-line Software (PROS) package was developed by SAO and runs in the IRAF environment. Although in recent years PROS was not a contractual responsibility of the RSDC, we continued to maintain the system and provided new capabilities such as the ability to deal with simulated AXAF data in preparation for the NASA call for proposals for Chandra. Our most recent activities in this area included the debugging necessary for newer versions of IRAF which broke some of our software. At SAO we have an operating version of PROS and hope to release a patch even though almost all functionality that was lost was subsequently recovered via an IRAF patch (i.e. most of our problems were caused by an IRAF bug).
This document contains the text of the 1989 UN Convention on the Rights of the Child. The Convention opens with a preamble which notes, among other things, that children are entitled to special care and assistance, that the family is the natural environment for the nurturing of children, and that international cooperation is important for improving the living conditions of children, especially in developing countries. Part 1 of the Convention contains 41 Articles which specify the rights of children to such things as protection against discrimination; proper care and protection; survival and development; a name and nationality; a unified family; freedom of expression, thought, conscience, religion, association, and peaceful assembly; access to information; adoption; having special needs met (in the case of handicapped children); health; social security; an adequate standard of living; education; rest and leisure; and protection from economic exploitation, illegal drugs, and sexual abuse. In addition, no child under the age of 15 years should serve in any armed forces. Parts 2 and 3 of the Convention deal with administrative issues such as the establishment of a Committee on the Rights of the Child as well as ratification, reservations, amendments, and denouncements of the Convention.

Global demand for organic produce is increasing by euro4 billion annually. One key reason why consumers buy organic food is because they consider it to be better for human and animal health. Reviews comparing organic and conventional food have stated that organic food is preferred by birds and mammals in choice tests. This study shows the opposite result-that captive birds in the laboratory and wild garden birds both consumed more conventional than organic wheat when given free choice. There was a lag in preference formation during which time birds learnt to distinguish between the two food types, which is likely to explain why the present results differ from those of previous studies. A further experiment confirmed that, of 16 potential causal factors, detection by birds of consistently higher levels of protein in conventional seeds (a common difference between many organic and conventional foodstuffs) is the likely mechanism behind this pattern. The results of this study suggest that the current dogma that organic food is preferred to conventional food may not always be true, which is of considerable importance for consumer perceptions of organically grown food.

To examine the efficacy of postural strategy training using a balance exercise assist robot (BEAR) as compared with conventional balance training for frail older adults. The present study was designed as a cross-over trial without a washout term. A total of 27 community-dwelling frail or prefrail elderly residents (7 men, 20 women; age range 65-85 years) were selected from a volunteer sample. Two exercises were prepared for interventions: robotic exercise moving the center of gravity by the balance exercise assist robot system; and conventional balance training combining muscle-strengthening exercise, postural strategy training and applied motion exercise. Each exercise was carried out twice a week for 6 weeks. Participants were allocated randomly to either the robotic exercise first group or the conventional balance exercise first group. preferred and maximal gait speeds, tandem gait speeds, timed up-and-go test, functional reach test, functional base of support, center of pressure, and muscle strength of the lower extremities were assessed before and after completion of each exercise program. Robotic exercise achieved significant improvements for tandem gait speed (P = 0.012), functional reach test (P = 0.002), timed up-and-go test (P = 0.023) and muscle strength of the lower extremities (P = 0.001-0.030) compared with conventional exercise. In frail or prefrail older adults, robotic exercise was more effective for improving dynamic balance and lower extremity muscle strength than conventional exercise. These findings suggest that postural strategy training with the balance exercise assist robot is effective to improve the gait instability and muscle weakness often seen in frail older adults.

Full Text Available Starting with the alphabetic stage of writing acquisition, the learner struggles with issues related to spelling, including the segmentation of writing in graphic words. This study examined the conventional segmentation of words and its relation to morphosyntactic awareness in a sample of students in the 4th and 5th years of elementary education in public schools. Results reveal a discrepancy between the oral identification of words and performance in the segmentation of writing, with three criteria being used by students to define “word”: (1st full meaning; (2nd sequence of letters, not only one or two; (3rd frequency of word use. Statistical analyses revealed significant positive correlations between conventional segmentation and morphosyntactic awareness. It is inferred that morphosyntactic skills support the establishment of the conventional notion of the word, and it is suggested that teachers promote the development of these skills, in order to ensure a greater command of the written language.
Conceptual definitions of the earth rotational parameters (ERP) used for obtaining astronomical references with an accuracy of 0.001 arcsec are reviewed, along with the fit between conceptual and conventional values. Conceptually, the instantaneous rotation of the earth is selected for calculating the ERP from a terrestrial frame of reference. It is shown that in calculating the third parameter, the UT1 value becomes unclear when it is related to the mean sidereal time using conventional models, and can be improved by using the stellar angle to obtain the angular speed of the earth in space directly. The accuracy of the value for the Celestial Ephemeris Pole (CEP) is demonstrated to be higher if considered conventionally in terms of the model of the precessional nutation of the earth. This formation accounts for the terrestrial motion of the instantaneous pole of rotation and the corresponding celestial motion.
Feedback suppression of resistive wall modes (RWM) is studied analytically using a model based on a standard cylindrical approximation. Two feedback systems are compared: 'ideal', creating only the field necessary for RMW suppression, and 'conventional', like that used in the DIII-D tokamak and considered as a candidate for ITER. The widespread opinion that the feedback with poloidal sensors is better than that with radial sensors is discussed. It is shown that the 'conventional' feedback with radial sensors can be effective only in a limited range, while using the input signal from internal poloidal sensors allows easy fulfilment of the stability criterion. This is a property of the 'conventional' feedback, but the 'ideal' feedback would stabilise RWM in both cases. (author)
Full Text Available This paper investigates the potential threat to the prohibition of the hostile misuse of the life sciences embodied in the Biological and Toxin Weapons Convention from the rapid advances in the field of neuroscience. The paper describes how the implications of advances in science and technology are considered at the Five Year Review Conferences of the Convention and how State Parties have developed their appreciations since the First Review Conference in 1980. The ongoing advances in neurosciences are then assessed and their implications for the Convention examined. It is concluded that State Parties should consider a much more regular and systematic review system for such relevant advances in science and technology when they meet at the Seventh Review Conference in late 2011, and that neuroscientists should be much more informed and engaged in these processes of protecting their work from malign misuse.

We conducted a field trial in computer-assisted professional translation to compare Interactive Translation Prediction (ITP) against conventional post- editing (PE) of machine translation (MT) output. In contrast to the conventional PE set-up, where an MT system first produces a static translation...... hypothesis that is then edited by a professional translator (hence \\post-editing"), ITP constantly updates the translation hypothesis in real time in response to user edits. Our study involved nine professional translators and four reviewers working with the web-based CasMaCat workbench. Various new...... interactive features aiming to assist the post-editor were also tested in this trial. Our results show that even with little training, ITP can be as productive as conventional PE in terms of the total time required to produce the final translation. Moreover, in the ITP setting translators require fewer key...

Can the increasing global energy consumption be met without intensifying global warming? Do the necessary technical solutions exist, and is the switch to a low-carbon energy supply feasible and financially viable? These crucial questions and many others were dealt with at the 2011World Engineer’s Convention (WEC). CERN was invited to participate in the event, highlighting its significant contribution to global engineering with an exhibition space devoted to the LHC on the convention floor and a keynote speech delivered by CERN’s Director-General.

A comparative study on the pyrolysis kinetics of moso bamboo has been conducted in a conventional thermogravimetric analyzer and a microwave thermogravimetric analyzer respectively. The effect of heating rate on the pyrolysis process was also discussed. The results showed that both the maximum and average reaction rates increased with the heating rate increasing. The values of activation energy increased from 58.30 to 84.22 kJ/mol with the heating rate decreasing from 135 to 60 °C/min during conventional pyrolysis. The value of activation energy was 24.5 kJ/mol for microwave pyrolysis, much lower than that for conventional pyrolysis at a similar heating rate of 160 °C/min. The pyrolysis of moso bamboo exhibited a kinetic compensation effect. The low activation energy obtained under microwave irradiation suggests that microwaves heating would be a promising method for biomass pyrolysis. Copyright © 2014 Elsevier Ltd. All rights reserved.

Computed tomography (CT) and conventional radiography were compared in 52 calcaneal fractures. As for CT, direct coronal imagings were performed in all and direct axial imagings were added in 27 of them. Conventional radiography included lateral, axial, and Anthonsen (oblique) views. Overall CT detected 7 more of the incongruity of the posterior facet, 9 more of the bulging of the lateral wall, and 6 more of the fracture of the sustentaculum tali than conventional radiography. In addition the entrapment of the peroneal tendons between the calcaneal body and the fibular malleolus could be evaluated only with CT. These informations are indispensable for the proper treatment of the fractures and we conclude that CT is useful in evaluating calcaneal fractures. (author).

The post-Cold War period has provided several spectacular breakthroughs in what seemed to be intractable arms control problems that were pushing the world to the brink of global disaster. One of the serious remaining gaps is the still largely unrestricted flow of conventional weapons, whose increasing sophistication and overkill potential is understandably a matter of growing concern. In addition to recognizing the continued priority of curbing the spread of weapons of mass destruction and drastically reducing their stockpiles, the time has come to engage major weapons exporters in developing new international understandings and mechanisms to stop the flood of conventional arms on the global market and to drastically curb conventional arms transfers.

The pH of conventional peritoneal dialysis solution is normally in the range of 5.0 to 5.5, because acid has been added during the manufacturing process to prevent caramelization of dextrose during sterilization. We studied the effects of normalizing the pH of conventional peritoneal dialysis solution on superoxide production by normal human neutrophils. At a pH of 6.0, superoxide generation was 4.07 +/- 2.56 (SD) nanomoles per million cells. With normalization of pH to 7.4, superoxide production was 19.3 +/- 7.3 (p less than 0.001). The results suggest that the unphysiologic acidity of conventional peritoneal dialysis solution has deleterious consequences on neutrophil superoxide formation.

In this study, we demonstrate the design of a Krueger flap as a substitute for a conventional slat in a high-lift system. This notional design, with the objective of matching equivalent-mission performance on aircraft approach, was required for a comparative aeroacoustic study with computational and experimental components. We generated a family of high-lift systems with Krueger flaps based on a set of design parameters. Then, we evaluated the high-lift systems using steady 2D RANS simulations to find a good match for the conventional slat, based on total lift coefficients in free-air. Finally, we evaluated the mean aerodynamics of the high-lift systems with Krueger flap and conventional slat as they were installed in an open-jet wind tunnel flow. The surface pressures predicted with the simulations agreed well with experimental results.

Magnetic resonance imaging (MRI) provides an in vivo assessment of cortical and subcortical regions affected in Parkinson's disease (PD). This review summarizes the most important conventional and non-conventional MRI techniques applied in this field. Standard neuroimaging techniques have played a marginal role in the diagnosis and follow-up of PD, essentially being used only to discriminate atypical syndromes from PD, to exclude secondary causes such as vascular lesions, and to confirm the absence of specific imaging features found in atypical parkinsonisms. However, non-conventional MRI techniques, i.e. new neuroimaging approaches such as magnetic resonance spectroscopy, diffusion tensor imaging, and functional MRI, may allow the detection of structural, functional and metabolic changes useful not only for differential diagnosis, but also for early diagnosis and outcome and treatment monitoring in PD. In addition, we illustrate the advantages of high-field MRI over lower magnetic fields, highlighting the great potential of advanced neuroimaging techniques.

This project consisted of three main components 1) The primary goal of the project was to renovate and upgrade an existing commercial building to the highest possible environmentally sustainable level for the purpose of creating an energy incubator. This initiative was part of the Infrastructure Technologies Program, through which a sustainable energy demonstration facility was to be created and used as a research and community outreach base for sustainable energy product and process incubation; 2) In addition, fundamental energy related research on wind energy was performed; a shrouded wind turbine on the Youngstown State University campus was commissioned; and educational initiatives were implemented; and 3) The project also included an education and outreach component to inform and educate the public in sustainable energy production and career opportunities. Youngstown State University and the Tech Belt Energy Innovation Center (TBEIC) renovated a 37,000 square foot urban building which is now being used as a research and development hub for the region’s energy technology innovation industry. The building houses basic research facilities and business development in an incubator format. In addition, the TBEIC performs community outreach and education initiatives in advanced and sustainable energy. The building is linked to a back warehouse which will eventually be used as a build-out for energy laboratory facilities. The projects research component investigated shrouded wind turbines, and specifically the “Windcube” which was renamed the “Wind Sphere” during the course of the project. There was a specific focus on the development in the theory of shrouded wind turbines. The goal of this work was to increase the potential efficiency of wind turbines by improving the lift and drag characteristics. The work included computational modeling, scale models and full-sized design and construction of a test turbine. The full-sized turbine was built on the YSU

The CF Metadata Conventions define attributes that promote sharing of climate and forecasting data and facilitate automated processing by computers. The development, maintenance, and evolution of the conventions have mainly been provided by voluntary community contributions. Nevertheless, an organizational framework has been established, which relies on established rules and web-based discussion to ensure smooth (but relatively efficient) evolution of the standard to accommodate new types of data. The CF standard has been essential to the success of high-profile internationally-coordinated modeling activities (e.g, the Coupled Model Intercomparison Project). A summary of CF's founding principles and the prospects for its future evolution will be discussed.
The NASA New England Outreach Center in Nashua, New Hampshire was established to serve as a catalyst for heightening regional business awareness of NASA procurement, technology and commercialization opportunities. Emphasis is placed on small business participation, with the highest priority given to small disadvantaged businesses, women-owned businesses, HUBZone businesses, service disabled veteran owned businesses, and historically black colleges and universities and minority institutions. The Center assists firms and organizations to understand NASA requirements and to develop strategies to capture NASA related procurement and technology opportunities. The establishment of the NASA Outreach Center serves to stimulate business in a historically underserved area. NASA direct business awards have traditionally been highly present in the West, Midwest, South, and Southeast areas of the United States. The Center guides and assists businesses and organizations in the northeast to target opportunities within NASA and its prime contractors and capture business and technology opportunities. The Center employs an array of technology access, one-on-one meetings, seminars, site visits, and targeted conferences to acquaint Northeast firms and organizations with representatives from NASA and its prime contractors to learn about and discuss opportunities to do business and access the inventory of NASA technology. This stimulus of interaction also provides firms and organizations the opportunity to propose the use of their developed technology and ideas for current and future requirements at NASA. The Center provides a complement to the NASA Northeast Regional Technology Transfer Center in developing prospects for commercialization of NASA technology. In addition, the Center responds to local requests for assistance and NASA material and documents, and is available to address immediate concerns and needs in assessing opportunities, timely support to interact with NASA Centers on

Patients with moderate-to-severe mixed hearing losses (MHLs) are hard to provide sufficient benefit with currently available conventional hearing aids. Here, the long-term safety of a direct acoustic cochlear stimulator (DACS) and the effectiveness compared with conventional "high-performance" hearing aids were investigated. Prospective, within patient reference, nonrandomized, interventional multicenter clinical study performed at these 3 centers: Medical University Hannover, University of Heidelberg, and Helios Hospital Krefeld. Ten otosclerosis patients with severe-to-profound MHL were preoperatively fitted with state-of-the-art conventional hearing aids (HA). After 2 months of testing conventional HA, 9 of the patients decided to be implanted with a DACS. Air conduction (AC) and bone conduction (BC) aided and unaided thresholds, speech discrimination before and after implantation and at 3, 6, and 12 months after activation. The subjective benefit was assessed by the Abbreviated Profile of Hearing Aid Benefit (APHAB). Preoperative hearing thresholds were preserved over the 12 month observation time after activation. Average functional gain (0.5-4 kHz) achieved with conventional HA was 47 dB compared with 56 dB with the DACS. Speech-in-noise tests revealed a lower SNR for DACS (3.1 dB) than for the HA (6.6 dB) and patients were more satisfied with the DACS. The DACS significantly improved hearing, speech intelligibility, and satisfaction in patients with a severe-to-profound mixed hearing loss and can be considered a safe and useful alternative to conventional hearing aids.

Pictorial messages have previously been advocated for interstellar communication because such messages are presumed to be capable of presenting information in a non-arbitrary and easily intelligible manner. In contrast to this view, pictorial messages actually represent information in a partially conventional way. This point is demonstrated by examining pictorial representations of human beings from a range of cultures. While such representations may be understood quite readily by individuals familiar with the conventions of a particular culture, to the uninitiated outsider, such representations can be unintelligible. In spite of the partially arbitrary nature of pictorial representation, we may be able to construct messages that would teach extraterrestrial intelligence (ETI) some of the conventions by which we view pictures. One such approach is to pair numerical information about geometrical objects with pictorial representations of the same objects. Problems of conventionality can also be addressed in part through use of (1) multiple representations of the same object, (2) contextual cues, (3) three- and four-dimensional representations and (4) non-visual representations.

Our objective was to investigate the accuracy and the diagnostic value of different imaging features of primary aneurysmal bone cysts (ABC) in conventional radiographs and MRI. Conventional radiographs and MR images of 34 patients with a suspected aneurysmal bone cyst were reevaluated by six independent radiologists in a blinded fashion. Morphological features, MR signal characteristics, and contrast enhancement patterns were assessed. Diagnoses were correlated with histology. Sensitivity and specificity of the different imaging findings for each imaging technique were calculated. In 24 patients ABC was histologically proven. In 10 cases diagnoses other than ABC were established. Conventional radiography and MRI each demonstrated a sensitivity of 76.4 and 77.8% with a specificity of 55.0 and 66.7%, respectively. With combined use of both imaging modalities sensitivity and specificity increased to 82.6 and 70%, respectively. The ABC was significantly more often seen as circumscribed lesion with bone expansion, lobulation, septa, and pathological cortical bone reaction than those cases with different diagnoses. Septal contrast enhancement proved to be a useful MR imaging finding in suspected ABC. The combined use of conventional radiographs and MRI revealed the highest sensitivity in the diagnosis of ABC in relation to histology. Magnetic resonance imaging provides improved diagnostic specificity and valuable information on soft tissue changes. (orig.)

Full Text Available The objective of the study was to compare the effect of organic and conventional cultivation on the antioxidant compound content and antioxidant activity of the Carmen tomato cultivar. Tomatoes were analyzed regarding ascorbic acid, phenolic compounds, lycopene content and antioxidant activity. Organic tomatoes presented higher content of ascorbic acid and total phenolics (641.39 and 4466.66 mg/100 g EAG on dry wt basis than did the conventional tomatoes (510.16 and 3477.50 mg/100 g EAG on wt dry basis, respectively. There was no difference in lycopene concentrations between the organic and conventional. The ether, alcohol and aqueous extracts obtained from the tomatoes were subjected to the DPPH test and the β-carotene/linoleic acid system assay. The alcohol and aqueous extracts from organic tomatoes presented higher antioxidant activity in the DPPH test (25.43 and 14.28%, respectively than the conventional tomatoes (19.52 and 11.33%, respectively. Organic tomatoes had higher antioxidant potential probably due to its higher ascorbic acid and total phenolic values.

Full Text Available The demand for organically produced food is increasing. There is widespread belief that organic food is substantially healthier and safer than conventional food. According to literature organic food is free of phytopharmaceutical residues, contain less nitrates and more antioxidants. The aim of the present study was to verify if there are any differences in the antioxidant activity between selected Slovenian organic and conventional crops. Method of DPPH (2,2-diphenyl-1-picryhydrazyl was used to determine the antioxidant activity of 16 samples from organic and conventional farms. The same varieties of crops were analysed. DPPH method was employed to measure the antioxidant activity of polar antioxidants (AAp and antioxidant activity of fraction in ethyl acetate soluble antioxidants (EA AA. Descriptive statistics and variance analysis were used to describe differences between farming systems. Estimated differences between interactions for the same crop and different farming practice were mostly not statistically significant except for the AAp for basil and beetroot. Higher statistically significant values were estimated for conventional crops. For the EA AA in broccoli, cucumber, rocket and cherry statistically significant higher values were estimated for organic production.

Evaluation of the fractured pelvis or acetabulum requires both standard radiographic evaluation as well as computed tomography (CT) imaging. The standard anterior-posterior (AP), Judet, and inlet and outlet views can now be simulated using data acquired during CT, decreasing patient discomfort, radiation exposure, and cost to the healthcare system. The purpose of this study is to compare the image quality of conventional radiographic views of the traumatized pelvis to virtual radiographs created from pelvic CT scans. Five patients with acetabular fractures and ten patients with pelvic ring injuries were identified using the orthopedic trauma database at our institution. These fractures were evaluated with both conventional radiographs as well as virtual radiographs generated from a CT scan. A web-based survey was created to query overall image quality and visibility of relevant anatomic structures. This survey was then administered to members of the Orthopaedic Trauma Association (OTA). Ninety-seven surgeons completed the acetabular fracture survey and 87 completed the pelvic fracture survey. Overall image quality was judged to be statistically superior for the virtual as compared to conventional images for acetabular fractures (3.15 vs. 2.98, p = 0.02), as well as pelvic ring injuries (2.21 vs. 1.45, p = 0.0001). Visibility ratings for each anatomic landmark were statistically superior with virtual images as well. Virtual radiographs of pelvic and acetabular fractures offer superior image quality, improved comfort, decreased radiation exposure, and a more cost-effective alternative to conventional radiographs.

Relationships between endogenous levels of polyamines by thin layer chromatography (TLC) and gas chromatography (GC), nitrate and response to the application of ethylene were established between organic and conventional vegetables (broccoli, collard greens, carrots and beets), both raw and cooked. Responses to ethylene showed that organic plants were less responsive to the growth regulator. The levels of free polyamines obtained by TLC were higher in organic vegetables. Organic broccoli showed higher levels of putrescine (Put), and cooking resulted in lowering the overall content of these amines. Conventional collard green showed the highest level of putrescine in the leaves compared with organic. Tubers of carrots and beets contain the highest levels of Put. These plants also contain high levels of spermine. GC analysis showed the highest polyamines contents compared with those obtained by TLC. Cooking process decreased putrescine and cadaverine content, both in conventionally and organically grown vegetables. Organic beets contain lower NO3(-) compared with its conventional counterpart.

Global increases in human population are creating an ever-greater need for food production. Poor soil management practices have degraded soil to such an extent that rapidly improved management practices is the only way to ensure future food demands. In South Africa, deciduous fruit producers are realising the need for soil health, and for an increased understanding of the benefits of soil ecology, to ensure sustainable fruit production. This depends heavily on improved orchard management. Conventional farming relies on the addition of artificial fertilizers, and the application of chemicals, to prevent or minimise, the effects of the soil stages of pest insects, and of plant-parasitic nematodes. Currently, there is resistance toward conventional farming practices, which, it is believed, diminishes biodiversity within the soil. The study aimed to establish the soil nematode community structure and function in organically, and conventionally, managed deciduous fruit orchards. This was done by determining the abundance, the diversity, and the functionality of the naturally occurring free-living, and plant-parasitic, nematodes in deciduous fruit orchards in the Western Cape province of South Africa. The objective of the study was to form the basis for the use of nematodes as future indicators of soil health in deciduous fruit orchards. Orchards from neighbouring organic, and conventional, apricot farms, and from an organic apple orchard, were studied. All the nematodes were quantified, and identified, to family level. The five nematode-classified trophic groups were found at each site, while 14 families were identified in each orchard, respectively. Herbivores were dominant in all the orchards surveyed. Organic apples had the fewest herbivores and fungivores, with the highest number of carnivores. When comparing organic with conventional apricot orchards, higher numbers of plant-parasitic nematodes were found in the organic apricot orchards. The Maturity Index (MI
Full Text Available Introduction Quality control techniques used to test the components of the radiological system and verify that the equipment is operating satisfactorily. In this study, quality control (QC assessment of conventional radiology devices was performed in frequently visited radiology centers of Khuzestan province, Iran. Materials and Methods Fifteen conventional radiology devices were examined, based on the protocol proposed in Report No. 77 by the Institute of Physics and Engineering in Medicine (IPEM. Ten standard QC tests, including voltage accuracy and reproducibility, exposure time accuracy and reproducibility, tube output linearity (time and milliampere, filtration (half-value layer, tube output (70 kV at FSD =100 cm, tube output reproducibility and beam alignment were performed and assessed. All measurements were performed, using Barracuda multi-purpose detector. Results The reproducibility of voltage, exposure time and dose output, as well as output linearity, met the standard criteria in all devices. However, in 60% of the units, the results of the beam alignment test were poor. We also found that 66.7% of the studied units offer services to more than 18,000 patients annually or 50 patients per day. Conclusion Despite the fact that radiological devices in Khuzestan province are relatively old with high workload, the obtained results showed that these devices met the standard criteria. This may be mainly related to proper after-sale services, provided by the companies. Although these services may be expensive for radiology centers, the costs may be significantly reduced if QC is defined as a routine procedure performed by qualified medical physicists or radiation safety officers.

Biodiversity studies that guide agricultural subsidy policy have generally compared farming systems at a single spatial scale: the field. However, diversity patterns vary across spatial scales. Here, we examined the effects of farming system (organic vs. conventional) and position in the field (edge vs. center) on plant species richness in wheat fields at three spatial scales. We quantified alpha-, beta-, and gamma-diversity at the microscale in 800 plots, at the mesoscale in 40 fields, and at the macroscale in three regions using the additive partitioning approach, and evaluated the relative contribution of beta-diversity at each spatial scale to total observed species richness. We found that alpha-, beta-, and gamma-diversity were higher in organic than conventional fields and higher at the field edge than in the field center at all spatial scales. In both farming systems, beta-diversity at the meso- and macroscale explained most of the overall species richness (up to 37% and 25%, respectively), indicating considerable differences in community composition among fields and regions due to environmental heterogeneity. The spatial scale at which beta-diversity contributed the most to overall species richness differed between rare and common species. Total richness of rare species (present in organic fields. Total richness of common species (present in > or = 25% of total samples) was explained by differences in community composition at the micro- and mesoscale (up to 29% and 47%, respectively), i.e., among plots and fields, independent of farming system. Our results show that organic farming made the greatest contribution to total species richness at the meso (among fields) and macro (among regions) scale due to environmental heterogeneity. Hence, agri-environment schemes should exploit this large-scale contribution of beta-diversity by tailoring schemes at regional scales to maximize dissimilarity between conservation areas using geographic information systems

We aimed to compare the outcome of MI to the conventional approach for coronary artery bypass graft (CABG surgery. Methods: This prospective, comparative study was conducted at a tertiary care cardiac surgical center. All patients who underwent CABG surgery via MI approach (MI group from July 2015 to December 2015 were enrolled and were compared against same number of EuroSCORE II matched patients undergoing CABG through conventional mid-sternotomy approach (CON group. Demographic, intra- and post-operative variables were collected. Results: In MI group, duration of the surgery was significantly longer (P = 0.029. Intraoperative blood loss lesser (P = 0.002, shorter duration of ventilation (P = 0.002, shorter Intensive Care Unit stay (P = 0.004, shorter hospital stay (P = 0.003, lesser postoperative analgesic requirements (P = 0.027, and lower visual analog scale scores on day of surgery (P = 0.032 and 1 st postoperative day (P = 0.025. No significant difference in postoperative blood loss, blood transfusion, or duration of inotrope requirement observed. There was no conversion to mid-sternotomy in any patients, 8% of patients had desaturation intraoperatively. There was no operative mortality. Conclusion: MI surgery is associated with lesser intraoperative blood loss, better analgesia, and faster recovery.
Full Text Available Being a non-party to the 1951 Convention relating to the Status of Refugees (“1951 Refugee Convention” and 1967 Protocol relating to the Status of Refugees (“1967 Protocol”, Indonesia does not have legal obligations to provide permanent resettlement for asylum seeker and/or refugee. However, as a transit country for those seeking shelter in Australia, Indonesia undergoes a myriad of issues resulting from illegal entrance by asylum seeker and/or refugee. Besides having neither legal framework nor domestic mechanism to handle asylum seekers and/or refugee, Indonesia’s immigration law identifies every foreigner including asylum seeker and refugee who unlawfully enter Indonesia’s territory into the same box as illegal migrant. It then leads to the arrest of asylum seeker and/or refugee to be put in an over-capacity detention center or other places. This paper will analyze various issues related to asylum seeker and refugee in Indonesia and to weigh whether it is indispensable for Indonesia to accede to the 1951 Refugee Convention and its 1967 Protocol.

Numerous reports have emphasized the need for major changes in the global food system: agriculture must meet the twin challenge of feeding a growing population, with rising demand for meat and high-calorie diets, while simultaneously minimizing its global environmental impacts. Organic farming—a system aimed at producing food with minimal harm to ecosystems, animals or humans—is often proposed as a solution. However, critics argue that organic agriculture may have lower yields and would therefore need more land to produce the same amount of food as conventional farms, resulting in more widespread deforestation and biodiversity loss, and thus undermining the environmental benefits of organic practices. Here we use a comprehensive meta-analysis to examine the relative yield performance of organic and conventional farming systems globally. Our analysis of available data shows that, overall, organic yields are typically lower than conventional yields. But these yield differences are highly contextual, depending on system and site characteristics, and range from 5% lower organic yields (rain-fed legumes and perennials on weak-acidic to weak-alkaline soils), 13% lower yields (when best organic practices are used), to 34% lower yields (when the conventional and organic systems are most comparable). Under certain conditions—that is, with good management practices, particular crop types and growing conditions—organic systems can thus nearly match conventional yields, whereas under others it at present cannot. To establish organic agriculture as an important tool in sustainable food production, the factors limiting organic yields need to be more fully understood, alongside assessments of the many social, environmental and economic benefits of organic farming systems.
Full Text Available The Russian Parliament has modified the Civil Code recently. This reform has also covered the regime of uncertificated securities. Under the modified Civil Code (RCC uncertificated securities do not constitute chattels but claims and other rights against the issuer. The legislator has also precised such issues as the methods of transfer and the creation of an interest upon those securities (Art. 149.2 of the RCC, the protection of the titleholder including the rights of a bona fide purchaser (Art. 149.3 of the RCC and the liability of an intermediary resulting from the loss of the records (Art. 149.5 of the RCC.In 2008, in Switzerland, the Parliament has adopted the Federal Intermediated Securities Act (FISA. The present Act has introduced a new object to the Swiss legal order: an intermediated security. The intermediated securities are distinguished from those in paper form and from the immobilized securities. The Swiss delegation has participated actively in the preparatory works that resulted later in the adoption of the UNIDROIT Convention on Substantive Rules for Intermediated Securities, also known as Geneva Securities Convention. However, this Convention has not been ratified by Switzerland.The author analyzes the key issues of the reform in relation to uncertificated securities. We examine in particular whether the provisions governing the regime of uncertificated securities under the modified Civil Code of the Russian Federation have become more compatible with Geneva Securities Convention. Finally, we will try to explain why this Convention is not in force and whether the Russian Federation and Switzerland could ratify it.

To compare MR myelography(MRM) using heavily T2 weighted fast spin echo(FSE) with conventional myelography in the evaluation of lumbar degenerative disc diseases. A total of 50 patients with lumbar degenerative disc diseases underwent both MRM and conventional myelography. A 1.5 T Sigma MR system was used. For MRM, heavily T2 weighted FSE pulse sequences were performed in sagittal, coronal and both oblique planes. The images of MRM and conventional myelography were analyzed retrospectively and compared, focusing on the pattern of compression of the cal sac and nerve roots. MRM yielded comparable images to conventional myelography in 68% (34/50). MRM was superior to conventional myelography in 11 cases (22%), and the opposite resulted in 5 cases(10%). MRM could visualize the spinal canal below the level of complete block in 6 patients, provided better contrast in the cases of dural ectasia in 3 cases and better delineation of individual nerve roots with source images in 1 case. Additional informations such as incidental retroperitoneal vascular malformation and extravasation of the CSF could be obtained by MRM in 1 case each. Disadvantages of MRM were poor contrast in the cases of multiple spinal stenosis, obscuration of the nerve roots by engorged paraspinal vessels, and occasional difficulty in defining the levels due to vanishment of the bony background image. MRM is a safe, noninvasive, nonionizing which in very effective in evaluating the lumbosacral disc disease. Use of FSE-MRM in addition to the routine MR imaging could be very helpful not only for better evaluation of nerve roots but also for the additional informations.

To determine the association of strabismus surgery reoperation rates with adjustable or conventional sutures. Retrospective cross-sectional study. setting: Review of a large national private insurance database. Adults aged 18-89 having strabismus surgery between 2007 and 2011. Adjustable vs conventional suture strabismus surgery. Reoperation rate in the first postoperative year. Overall, 526 of 6178 surgical patients had a reoperation (8.5%). Reoperations were performed after 8.1% of adjustable suture surgeries and after 8.6% of conventional suture surgeries (P = .57). Of the 4357 horizontal muscle surgeries, reoperations were performed after 5.8% of adjustable suture surgeries, and after 7.8% of conventional suture surgeries (P = .02). Of the 1072 vertical muscle surgeries, reoperations were performed after 15.2% of adjustable suture surgeries and after 10.4% of conventional suture surgeries (P = .05). Younger age (18-39 years) was associated with a lower reoperation rate (P ≤ .02). The significant multivariable predictors of reoperation for horizontal surgery were adjustable sutures (odds ratio [OR] 0.69, 95% confidence interval 0.52-0.91), monocular deviation (OR 0.64), complex surgery (OR 1.63), and unilateral surgery on 2 horizontal muscles (OR 0.70, all P ≤ .01). Adjustable sutures were not significantly associated with reoperation rates after vertical muscle surgery (multivariable OR 1.45, P = .07). Adjustable sutures were associated with significantly fewer reoperations for horizontal muscle surgery. Adjustable sutures tended to be associated with more reoperations for vertical muscle surgery, but this observation was not statistically significant in the primary analysis after controlling for age.

Full Text Available Many species of Fusariumfungi can produce a number of different mycotoxins including trichothecenes such as deoxynivalenol (DON, nivalenol (NIV, zearalenone (ZEA and others. The farming system have an effect on quality of grown plants, including mycotoxin contamination. The contamination of winter wheat (Triticum aestivumL. and rye grain by toxins with focus on the genus Fusarium was monitored within the years 2009 –2011 under the official control according to EC Regulation 401/2006 and 178/2010 on the territory of the Slovak Republic in organic and conventional grains. The concentration of deoxynivalenol (DON was determined by HPLC/DAD detector and concentration of zearalenone (ZEA by HPLC/FLD detector. Results of analysed samples showed that DON was the most prevalent Fusarium toxin. In the analysed samples were observed significant differences between organic and conventional wheat samples. Results showed that samples from organic production contained significantly lower contamination of DON and ZEA mycotoxins than from conventional production. In four wheat samples from conventional production was the content of DON over the EC Regulation no. 1881/2006 about setting the maximum levels for certain contaminants in foodstuff. Within the observed period, the highest DON concentrations were observed in the year 2010, in both wheat and rye samples, and organic and conventional production. The year 2010 was characterised by constant rain, moist soil on the most area of Slovakia. Since lower contamination of Fusarium toxins was found in wheat and rye from organic farming, it can be concluded, that factors related to agricultural practices in this system can reduce the risk of Fusarium mycotoxin contamination.

After the aging process, the brackets were analyzed by scanning electron microscopy (SEM under 22X and 1,000X magnifications. Results: Comparison of metal release in self-ligating and conventional brackets from the same manufacturer proved that the SCs group released more nickel (p < 0.05 than the GN group after 7 and 14 days, but less chromium (p < 0.05 after 14 days and less iron (p < 0.05 at the three experimental time intervals. The INs group released less iron (p < 0.05 than the GE group after 7 days and less nickel, chromium and iron (p < 0.05 after 14 and 21 days. The ECs group released more nickel, chromium and iron (p < 0.05 than the VE group after 14 days, but released less nickel and chromium (p < 0.05 after 7 days and less chromium and iron (p < 0.05 after 21 days. The SEM analysis revealed alterations on surface topography of conventional and self-ligating brackets. Conclusions: The aging process in self-ligating brackets was not greater than in conventional brackets from the same manufacturer. The null hypothesis was accepted.

The sulfur distributions and evolution of sulfur-containing compounds in the char, tar and gas fractions were investigated during the microwave and conventional pyrolysis of sewage sludge. Increased accumulation of sulfur in the char and less production of H2S were obtained from microwave pyrolysis at higher temperatures (500-800 °C). Three similar conversion pathways were identified for the formation of H2S during microwave and conventional pyrolysis. The cracking of unstable mercaptan structure in the sludge contributed to the release of H2S below 300 °C. The decomposition of aliphatic-S compounds in the tars led to the formation of H2S (300-500 °C). The thermal decomposition of aromatic-S compounds in the tars generated H2S from 500 to 800 °C. However, the secondary decomposition of thiophene-S compounds took place only in conventional pyrolysis above 700 °C. Comparing the H2S contributions from microwave and conventional pyrolysis, the significant increase of H2S yields in conventional pyrolysis was mainly attributed to the decomposition of aromatic-S (increasing by 10.4%) and thiophene-S compounds (11.3%). Further investigation on the inhibition mechanism of H2S formation during microwave pyrolysis confirmed that, with the special heating characteristics and relative shorter residence time, microwave pyrolysis promoted the retention of H2S on CaO and inhibited the secondary cracking of thiophene-S compounds at higher temperatures.

While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters. We assessed for successful acquisition of good quality angiogram, completion of the angioplasty and access site complications. 5 Fr sheathless cardiac catheterization was undertaken in diagnostic (55%) and PCI cases (45%, all indications) in 60 consecutive patients (mean age 62.8±11.4years) using conventional catheters. The procedure was successfully performed via the radial artery using a sheathless technique with BAT in 93.3% of patients. All patients had a patent radial artery following removal of the Helix device and there were no recorded access site complications. Trans-radial cardiac catheterisation for diagnostic and PCI cases using 5F Sheathless catheters (whose outer diameter is smaller than a 3Fr introducer sheath) with BAT appears feasible and allows both cardiac catheterization for diagnostic and PCI indications to be undertaken safely using conventional catheters through the radial route, with high success rates.

Full Text Available Introduction. Congenital pelviureteric junction obstruction (PUJO is one of the most common causes of hydronephrosis. Historically, open dismembered pyeloplasty has been considered the gold standard intervention for correcting PUJO. The aim of this study was to compare the surgical and functional outcomes of three different approaches, namely, open, conventional laparoscopy, and robotic pyeloplasty. Material and Methods. 60 patients underwent minimally invasive pyeloplasty (30 conventional laparoscopies and 30 robotics for congenital PUJO at a tertiary health center in India. Demographic, perioperative, and postoperative data were prospectively collected and analyzed. The data of these patients were retrospectively compared with another cohort of 30 patients who had undergone open pyeloplasty. Results. There was significant difference in operative time, time to drain removal, hospital stay, pain score, and complications rate between open and minimally invasive pyeloplasty (P<0.05. SFI was considerably lesser in robotic as compared to conventional laparoscopy. The success rate in OP, CLP, and RP was 93.33, 96.67, and 96.67%. Conclusion. Robotic pyeloplasty is safe, effective, and feasible. It is associated with significantly lesser operative time, lesser blood loss, less pain, shorter hospital stay, and fewer complications. It is also associated with considerably lesser surgeon fatigue as compared to conventional laparoscopy pyeloplasty.

Background and objectives No data on the development of conventional indications for RRT (refractory acidosis, hyperkalemia, uremia, oliguria/anuria, and volume overload) related to timing of RRT exist. The prevalence of conventional indications among critically ill patients on RRT for AKI was evaluated, and patients manifesting indications versus patients without indications were compared in terms of crude and adjusted 90-day mortality. Design, setting, participants, & measurements In this substudy of the Finnish Acute Kidney Injury study conducted in 2011 and 2012 in 17 intensive care units with 2901 patients, patients were classified as pre-emptive (no conventional indications) and classic (one or more indications) RRT recipients. Patients with classic RRT were divided into classic-urgent (RRT initiated ≤12 hours from manifesting indications) and classic-delayed (RRT >12 hours from first indication). Additionally, 2450 patients treated without RRT were matched to patients with pre-emptive RRT. Results Of 239 patients treated with RRT, 134 (56.1%; 95% confidence interval [95% CI], 49.8% to 62.4%) fulfilled at least one conventional indication before commencing RRT. Crude 90-day mortality of 134 patients with classic RRT was 48.5% (95% CI, 40.0% to 57.0%), and it was 29.5% (95% CI, 20.8% to 38.2%) for the 105 patients with pre-emptive RRT. Classic RRT was associated with a higher risk for mortality (adjusted odds ratio, 2.05; 95% CI, 1.03 to 4.09). Forty-four patients with classic–delayed RRT showed higher crude mortality (68.2%; 95% CI, 54.4% to 82.0%) compared with patients with classic–urgent RRT, and this association persisted after adjustment for known confounders (odds ratio, 3.85; 95% CI, 1.48 to 10.22). Crude 90-day mortality of 67 1:1 matched patients with pre-emptive RRT was 26.9% (95% CI, 6.3% to 37.5%), and it was 49.3% (95% CI, 37.3% to 61.2%; P=0.01) for their non-RRT matches. Conclusions Patients on RRT after one or more conventional
Full Text Available Ownership rights do not provide the owner with full freedom of use over the owned thing anymore, especially when it comes to such valuable resources as agricultural land. Ownership rigths are privilegia odiosa these days. Highest legal acts of several countries, as well as decisions of the Court of Justice of the European Union, stress the fact that it is not absolute and that it has a particular social function. The owner is obliged to use the land, and to do so in a conventional manner. Conventional should, with respect to logical reasoning, relate only to what has been accepted, by a broader community, as useful and reasonable. However, that is not always the case in modern world. Agriculture is considered conventional when it is directed towards intensive plant production, while making use of artificial fertilizers, growth hormones, pesticides, fungicides, insecticides, and other chemical products. In USA and some other countries, production of plants which have a DNA modified by use of techniques of genetic engineering (GMO, are treated under the same legal regime. On the other hand, traditional, organic agriculture is treated as an exception, and special, more restrictive rules are applied to it. Civilization obviously found itself in an absurd situation. Something for which it is undoubtedly clear that it is bad in many aspects, and long term unsustainable (conventional agriculture is considered normal, something for which it is not known whether and to which extent it is harmful (GMO agriculture is being tolerated, and something for which we confidently know that it is not harmful, or at least not as nearly as harmful as the previously mentioned is considered an exception (organic agriculture. The difference between GMO immissions and emissions from a certain property being allowed or prohibited, i.e. whether the owner of a particular property will be held responsible for disturbance and possible damage, as a result of contamination of

Sustainable food production for a growing world population requires a healthy soil that can buffer environmental extremes and minimize its losses. There are currently two views on how to achieve this: by intensifying conventional agriculture or by developing organically based agriculture. It has been established that yields of conventional agriculture can be 20% higher than of organic agriculture. However, high yields of intensified conventional agriculture trade off with loss of soil biodiversity, leaching of nutrients, and other unwanted ecosystem dis-services. One of the key explanations for the loss of nutrients and GHG from intensive agriculture is that it results in high dynamics of nutrient losses, and policy has aimed at reducing temporal variation. However, little is known about how different agricultural practices affect spatial variation, and it is unknown how soil fauna acts this. In this study we compare the spatial and temporal variation of physical, chemical and biological parameters in a long term (13-year) field experiment with two conventional farming systems (low and medium organic matter input) and one organic farming system (high organic matter input) and we evaluate the impact on ecosystem services that these farming systems provide. Soil chemical (N availability, N mineralization, pH) and soil biological parameters (nematode abundance, bacterial and fungal biomass) show considerably higher spatial variation under conventional farming than under organic farming. Higher variation in soil chemical and biological parameters coincides with the presence of 'leaky' spots (high nitrate leaching) in conventional farming systems, which shift unpredictably over the course of one season. Although variation in soil physical factors (soil organic matter, soil aggregation, soil moisture) was similar between treatments, but averages were higher under organic farming, indicating more buffered conditions for nutrient cycling. All these changes coincide with
