The Immunomodulatory Role of Adjuvants in Vaccines Formulated with the Recombinant Antigens Ov-103 and Ov-RAL-2 against Onchocerca volvulus in Mice.

Directory of Open Access Journals (Sweden)

Full Text Available In some regions in Africa, elimination of onchocerciasis may be possible with mass drug administration, although there is concern based on several factors that onchocerciasis cannot be eliminated solely through this approach. A vaccine against Onchocerca volvulus would provide a critical tool for the ultimate elimination of this infection. Previous studies have demonstrated that immunization of mice with Ov-103 and Ov-RAL-2, when formulated with alum, induced protective immunity. It was hypothesized that the levels of protective immunity induced with the two recombinant antigens formulated with alum would be improved by formulation with other adjuvants known to enhance different types of antigen-specific immune responses.Immunizing mice with Ov-103 and Ov-RAL-2 in conjunction with alum, Advax 2 and MF59 induced significant levels of larval killing and host protection. The immune response was biased towards Th2 with all three of the adjuvants, with IgG1 the dominant antibody. Improved larval killing and host protection was observed in mice immunized with co-administered Ov-103 and Ov-RAL-2 in conjunction with each of the three adjuvants as compared to single immunizations. Antigen-specific antibody titers were significantly increased in mice immunized concurrently with the two antigens. Based on chemokine levels, it appears that neutrophils and eosinophils participate in the protective immune response induced by Ov-103, and macrophages and neutrophils participate in immunity induced by Ov-RAL-2.The mechanism of protective immunity induced by Ov-103 and Ov-RAL-2, with the adjuvants alum, Advax 2 and MF59, appears to be multifactorial with roles for cytokines, chemokines, antibody and specific effector cells. The vaccines developed in this study have the potential of reducing the morbidity associated with onchocerciasis in humans.

1991-01-01

STS-48 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, is of the breakup of pack ice along the periphery of the Antarctic Ice Shelf. Strong offshore winds, probably associated with katabatic downdrafts from the interior of the continent, are seen peeling off the edges of the ice shelf into long filaments of sea ice, icebergs, bergy bits, and growlers to flow northward into the South Atlantic Ocean. These photos are used to study ocean wind, tide and current patterns. Similar views photographed during previous missions, when analyzed with these recent views may yield information about regional ice drift and breakup of ice packs. The image was captured using an electronic still camera (ESC), was stored on a removable hard disk or small optical disk, and was converted to a format suitable for downlink transmission. The ESC documentation was part of Development Test Objective (DTO) 648, Electronic Still Photography.

Grumman OV-1C in flight. This OV-1C Mohawk, serial #67-15932, was used in a joint NASA/US Army Aviation Engineering Flight Activity (USAAEFA) program to study a stall-speed warning system in the early 1980s. NASA designed and built an automated stall-speed warning system which presented both airspeed and stall speed to the pilot. Visual indication of impending stall would be displayed to the pilot as a cursor or pointer located on a conventional airspeed indicator. In addition, an aural warning at predetermined stall margins was presented to the pilot through a voice synthesizer. The Mohawk was developed by Grumman Aircraft as a photo observation and reconnaissance aircraft for the US Marines and the US Army. The OV-1 entered production in October 1959 and served the US Army in Europe, Korea, the Viet Nam War, Central and South America, Alaska, and during Desert Shield/Desert Storm in the Middle East. The Mohawk was retired from service in September 1996. 133 OV-1Cs were built, the 'C' designating the model which used an IR (infrared) imaging system to provide reconnaissance.

Measurement of 103mRh produced by the 103Rh(γ,γ')103mRh reaction with liquid scintillation counting

Sekine, T.; Yoshihara, Kenji; Pavlicsek, I.; Lakosi, L.; Veres, A.

1989-01-01

A liquid scintillation counting technique was applied to measure the isotope 103m Rh (half life = 56.12 min) which is difficult to detect because its γ-ray is of low energy and low emission probability. Tris-(2,4-pentanedionato)rhodium(III) (Rh(acac) 3 ) was irradiated with bremsstrahlung of accelerated 3.2 MeV electrons by LINAC. The method has given a reliable calibration curve for the determination of 103m Rh radioactivity below Rh(acac) 3 concentrations of 2 mM. The integrated cross section of 103 Rh(γ,γ') 103m Rh determined by this method was found to be 6.8±3.4 μb MeV at 3.2 MeV. (author) 8 refs.; 5 figs

Single classifier, OvO, OvA and RCC multiclass classification method in handheld based smartphone gait identification

Science.gov (United States)

Raziff, Abdul Rafiez Abdul; Sulaiman, Md Nasir; Mustapha, Norwati; Perumal, Thinagaran

2017-10-01

Gait recognition is widely used in many applications. In the application of the gait identification especially in people, the number of classes (people) is many which may comprise to more than 20. Due to the large amount of classes, the usage of single classification mapping (direct classification) may not be suitable as most of the existing algorithms are mostly designed for the binary classification. Furthermore, having many classes in a dataset may result in the possibility of having a high degree of overlapped class boundary. This paper discusses the application of multiclass classifier mappings such as one-vs-all (OvA), one-vs-one (OvO) and random correction code (RCC) on handheld based smartphone gait signal for person identification. The results is then compared with a single J48 decision tree for benchmark. From the result, it can be said that using multiclass classification mapping method thus partially improved the overall accuracy especially on OvO and RCC with width factor more than 4. For OvA, the accuracy result is worse than a single J48 due to a high number of classes.

Oviductal extracellular vesicles (oviductosomes, OVS) are conserved in humans: murine OVS play a pivotal role in sperm capacitation and fertility.

Are extracellular vesicles (EVs) in the murine oviduct (oviductosomes, OVS) conserved in humans and do they play a role in the fertility of Pmca4-/- females? OVS and their fertility-modulating proteins are conserved in humans, arise via the apocrine pathway, and mediate a compensatory upregulation of PMCA1 (plasma membrane Ca2+-ATPase 1) in Pmca4-/- female mice during proestrus/estrus, to account for their fertility. Recently murine OVS were identified and shown during proestrus/estrus to express elevated levels of PMCA4 which they can deliver to sperm. PMCA4 is the major Ca2+ efflux pump in murine sperm and Pmca4 deletion leads to loss of sperm motility and male infertility as there is no compensatory upregulation of the remaining Ca2+ pump, PMCA1. Of the four family members of PMCAs (PMCA1-4), PMCA1 and PMCA4 are ubiquitous, and to date there have been no reports of one isoform being upregulated to compensate for another in any organ/tissue. Since Pmca4-/- females are fertile, despite the abundant expression of PMCA4 in wild-type (WT) OVS, we propose that OVS serve a role of packaging and delivering to sperm elevated levels of PMCA1 in Pmca4-/- during proestrus/estrus to compensate for PMCA4's absence. Fallopian tubes from pre-menopausal women undergoing hysterectomy were used to study EVs in the luminal fluid. Oviducts from sexually mature WT mice were sectioned after perfusion fixation to detect EVs in situ. Oviducts were recovered from WT and Pmca4-/- after hormonally induced estrus and sectioned for PMCA1 immunofluorescence (IF) (detected with confocal microscopy) and hematoxylin and eosin staining. Reproductive tissues, luminal fluids and EVs were recovered after induced estrus and after natural cycling for western blot analysis of PMCA1 and qRT-PCR of Pmca1 to compare expression levels in WT and Pmca4-/-. OVS, uterosomes, and epididymal luminal fluid were included in the comparisons. WT and Pmca4-/- OVS were analyzed for the presence of known PMCA4 partners

Falla ovárica precoz

Directory of Open Access Journals (Sweden)

Full Text Available La falla ovárica precoz es una amenorrea secundaria que se presenta en una mujer antes de los 40 años, que conlleva a hipoestrogenismo, infertilidad y las consecuencias de la menopausia prematura, como osteoporosis, enfermedad cardiovascular, trastornos neurovegetativos, entre otros. Se presenta agotamiento folicular, por dotación insuficiente de folículos o destrucción acelerada de los ovocitos. Las causas son varias, pero predominan las genéticas, autoinmunes y las iatrogénicas. Entre las causas genéticas, son frecuentes las deleciones Xq y Xp, las translocaciones, aberraciones numéricas (47,XXX, 45,X0, premutaciones de X frágil, entre otros. Entre las enfermedades autoinmunes son de importancia la insuficiencia poliglandular tipo I y II. Las iatrogenias pueden ser quirúrgicas en ovarios o trompas y, con la presencia del cáncer de mama en mujeres jóvenes, el tratamiento oncológico puede destruir las células germinales, por lo que hoy se sugiere utilizar técnicas de preservación de la función ovárica y de la fertilidad. En el manejo de la falla ovárica precoz, una vez determinada la causa, se sugiere el uso de terapia estrogénica, aunque no se ha hecho investigación en el tipo de hormona a utilizar, dosis y consecuencias a largo plazo. Tener presente la prevención y manejo de la osteoporosis y la enfermedad cardiovascular. Con relación a la infertilidad, se está realizando criopreservación de embriones y ovocitos para autodonación, así como criopreservación de tejido ovárico cortical para autotrasplante posterior, con éxitos y limitaciones. Los agonistas de GnRH podrían actuar en proteger los ovarios en casos de quimioterapia. Se observa con atención la terapia génica experimental en casos de falla ovárica precoz.

NASA designed and built an automated stall-speed warning system which presented both airspeed and stall speed to the pilot. Visual indication of impending stall would be displayed to the pilot as a cursor or pointer located on a conventional airspeed indicator. In addition, an aural warning at predetermined stall margins was presented to the pilot through a voice synthesizer. The Mohawk was developed by Grumman Aircraft as a photo observation and electronic reconnaissance aircraft for the US Marines and the US Army. The OV-1 entered production in October 1959 and served the US Army in Europe, Korea, the Viet Nam War, Central and South America, Alaska, and during Desert Shield/Desert Storm in the Middle East. The Mohawk was retired from service in September 1996. 133 OV-1Cs were built, the 'C' designating the model which used an IR (infrared) imaging system to provide reconnaissance.

Full Text Available This paper presents the factors that influence the online marketing strategies of software vendors from Braşov County. An analysis of the software retailers’ attitudes from Braşov regarding online marketing and advertising was made. A survey among vendors from Braşov was undertaken and the results of this research show an orientation of lesser extent to online sales and marketing of the retailers’ activity. 20 responses were collected from software companies which trade software products and services in Braşov County. The results are very important for the companies that sell software products and services not only on the local market but also at national level. The paper presents the main reasons why software retailers from Braşov County, which is one of the most developed software markets in the country, have a lesser orientation towards online selling of software products and services. More than 400 companies involved in the software domain operate in Braşov City only. Research questions regarding the effects of the present economic situation, the online marketing strategies used in the software industry, and details about the online activity of each company where part of this research.

Full Text Available In the eighties, the Bessarabian nobleman Mihail Stroesku's attempts to support the Romanian Bessarabian education were rejected by the Russian authorities, so his philanthropic activities was conducted in the Kingdom of Romania, especially in Transylvania. "Association for Supporting Apprentices and Journeymen of Romanian Craftsmen of Braşov" was founded in 1869 by a group of Braşov intellectuals and merchants on the initiative of the priest Bartolomeu Baiulescu. The purpose of this organization was to help the apprentices and journeymen and to support craft activities in Braşov. The customs war, which broke out between Romania and Austria-Hungary in mid-1886, had serious consequences for the economy of Transylvania. The economic disorders provoked the migration of a significant part of manufacturers and workshop owners from Transylvania outside the Carpathian arc that worsened the financial problems of the craftsmen association from Braşov. On November 22, Mihail Stroesku and his wife Eliza donated the association 25,000 Austrian florins (50,000 lei. Over the years, the "Eliza and Mihail Stroescu Foundation" was one of the main sources of its funding. This money has been spent on manuals, materials, awards, scholarships, rent, material assistance, current expenditure etc.

Cytotoxic effect of essential oil of thyme (Thymus broussonettii on the IGR-OV1 tumor cells resistant to chemotherapy

Full Text Available The anti-tumor effect of the Moroccan endemic thyme (Thymus broussonettii essential oil (EOT was investigated in vitro using the human ovarian adenocarcinoma IGR-OV1 parental cell line OV1/P and its chemoresistant counterparts OV1/adriamycin (OV1/ADR, OV1/vincristine (OV1/VCR, and OV1/cisplatin (OV1/CDDP. All of these cell lines elicited various degrees of sensitivity to the cytotoxic effect of EOT. The IC50 values (mean ± SEM, v/v were 0.40 ± 0.02, 0.39 ± 0.02, 0.94 ± 0.05, and 0.65 ± 0.03% for OV1/P, OV1/ADR, OV1/VCR, and OV1/CDDP, respectively. Using the DBA-2/P815 (H2d mouse model, tumors were developed by subcutaneous grafting of tumor fragments of similar size obtained from P815 (murin mastocytoma cell line injected in donor mouse. Interestingly, intra-tumoral injection of EOT significantly reduced solid tumor development. Indeed, by the 30th day of repeated EOT treatment, the tumor volumes of the animals were 2.00 ± 0.27, 1.35 ± 0.20, and 0.85 ± 0.18 cm³ after injection with 10, 30, or 50 µL per 72 h (six times, respectively, as opposed to 3.88 ± 0.50 cm³ for the control animals. This tumoricidal effect was associated with a marked decrease of mouse mortality. In fact, in these groups of mice, the recorded mortality by the 30th day of treatment was 30 ± 4, 18 ± 4, and 8 ± 3%, respectively, while the control animals showed 75 ± 10% of mortality. These data indicate that the EOT which contains carvacrol as the major component has an important in vitro cytotoxic activity against tumor cells resistant to chemotherapy as well as a significant antitumor effect in mice. However, our data do not distinguish between carvacrol and the other components of EOT as the active factor.

Full Text Available SUMMARY Introduction: the EuroSCORE II and STS are the most used scores for surgical risk stratification and indication of transcatheter aortic valve implantation (TAVI. However, its role as a tool for mortality prediction in patients undergoing TAVI is still unclear. Objective: to evaluate the performance of the EuroSCORE II and STS as predictors of in-hospital and 30-day mortality in patients undergoing TAVI. Methods: we included 59 symptomatic patients with severe aortic stenosis that underwent TAVI between 2010 and 2014. The variables were analyzed using Student's t-test and Fisher's exact test and the discriminative power was evaluated using receiver operating characteristic curve (ROC and area under the curve (AUC with a 95% confidence interval. Results: mean age was 81±7.3 years, 42.3% men. The mean EuroSCORE II was 7.6±7.3 % and STS was 20.7±10.3%. Transfemoral procedure was performed in 88.13%, transapical in 3.38% and transaortic in 8.47%. In-hospital mortality was 10.1% and 30-day mortality was 13.5%. Patients who died had EuroSCORE II and STS higher than the survivors (33.7±16.7vs. 18.6±7.3% p=0,0001 for STS and 13.9±16.1 vs. 4.8±3.8% p=0.0007 for EuroSCORE II. The STS showed an AUC of 0.81 and the EuroSCORE II of 0.77 and there were no differences in the discrimination ability using ROC curves (p=0.72. Conclusion: in this cohort, the STS and EuroSCORE II were predictors of in-hospital and 30-days mortality in patients with severe aortic stenosis undergoing TAVI.

Full Text Available Desde mediados de la década de 1950 se aceptó el concepto que el número de ovocitos primarios está determinado desde el nacimiento. En 2004 inició el cambio de este paradigma de la fisiología ovárica al identificarse células madre de la línea germinal mitóticamente activas durante la vida posnatal en el ovario murino. En 2012 se identificó el equivalente de estas células en el ovario humano producto de un protocolo de clasificación de células activadas por fluorescencia que permitió su purificación y caracterización. La potencial aplicación de las células madre de origen ovárico hará posible asegurar la conservación de la función ovárica en condiciones clínicas, en donde la actividad reproductiva podría verse afectada, como es el caso de mujeres jóvenes con cáncer, que requieren de tratamiento que en la mayoría de los casos resulta en alteraciones de la función hormonal y gametogénica del ovario.

Nodding syndrome (NS) and Onchocerca Volvulus (OV) in Northern Uganda.

Lagoro, David Kitara; Arony, Denis Anywar

2017-01-01

Nodding Syndrome (NS) is a childhood neurological disorder characterized by atonic seizures, cognitive decline, school dropout, muscle weakness, thermal dysfunction, wasting and stunted growth. There are recent published information suggesting associations between Nodding Syndrome (NS) with cerebrospinal fluid (CSF) VGKC antibodies and serum leiomidin-1 antibody cross reacting with Onchocerca Volvulus ( OV ). These findings suggest a neuro-inflammatory cause of NS and they are important findings in the search for the cause of Nodding Syndrome. These observations perhaps provide further, the unique explanation for the association between Nodding Syndrome and Onchocerca Volvulus . Many clinical and epidemiological studies had shown a significant correlation between NS and infestation with a nematode, Onchocerca volvulus which causes a disease, Onchocerciasis , some of which when left untreated can develop visual defect ("River Blindness"). While these studies conducted in Northern Uganda and Southern Sudan indicate a statistically significant association with ( OV infection (using positive skin snips), we observe that ( OV is generally endemic in many parts of Sub Saharan Africa and Latin America and that to date, no NS cases have been recorded in those regions. This letter to the Editor is to provide additional information on the current view about the relationship between Nodding Syndrome and Onchocerca Volvulus as seen in Northern Uganda.

Ferritic stainless steels for the SOFC interconnect applications are required to possess not only a good oxidation resistance, but also a high electrical conductivity of te oxide scale that forms during exposure at the SOFC operating environment. In order to understand the effects of alloying elements on the oxidation behavior of ferritic stainless steels and on the electrical properties of oxide scales, two kinds of commercial ferritic stainless steels, STS 430 and STS 444, were investigated by performing isothermal oxidations at 800 .deg. C in a wet air containing 3% H 2 O. The results showed that STS 444 was superior to STS 430 in both of the oxidation resistance and the area specific resistance. Although STS 444 contained a less amount of Mn for the (Mn, Cr) 3 O 4 spinel formation than STS 430, the minor alloying elements of Al and Mo in STS 444, which were accumulated in the base metal region adjacent the scale, were suggested to reduce the scale growth rate and to enhance the scale adherence to the base metal

Recently it has been shown that Ensifer adhaerens can be used as a plant transformation technology, transferring genes into several plant genomes when equipped with a Ti plasmid. For this study, we have sequenced the genome of Ensifer adhaerens OV14 (OV14) and compared it with those of Agrobacterium tumefaciens C58 (C58) and Sinorhizobium meliloti 1021 (1021); the latter of which has also demonstrated a capacity to genetically transform crop genomes, albeit at significantly reduced frequencies. The 7.7 Mb OV14 genome comprises two chromosomes and two plasmids. All protein coding regions in the OV14 genome were functionally grouped based on an eggNOG database. No genes homologous to the A. tumefaciens Ti plasmid vir genes appeared to be present in the OV14 genome. Unexpectedly, OV14 and 1021 were found to possess homologs to chromosomal based genes cited as essential to A. tumefaciens T-DNA transfer. Of significance, genes that are non-essential but exert a positive influence on virulence and the ability to genetically transform host genomes were identified in OV14 but were absent from the 1021 genome. This study reveals the presence of homologs to chromosomally based Agrobacterium genes that support T-DNA transfer within the genome of OV14 and other alphaproteobacteria. The sequencing and analysis of the OV14 genome increases our understanding of T-DNA transfer by non-Agrobacterium species and creates a platform for the continued improvement of Ensifer-mediated transformation (EMT).

Highlights: ► The production of 103 Pd activity in 15 h of irradiation at 200 μA was calculated to be 685 mCi. ► MCNPX was used to calculate the energy distribution of the proton flux on the Rh target. ► The activity based on the MCNPX was calculated to be 674.58 mCi. - Abstract: The radionuclide 103 Pd (T 1/2 = 16.991 d; decays almost exclusively by EC to 103m Rh, T 1/2 = 56.114 min) has been of great interest in prostate and eye cancer therapy due to its suitable half-life and decay characteristics. 103 Pd has been produced by proton irradiation of a 103 Rh target through the 103 Rh(p,n) 103 Pd reaction. In this paper, the Monte Carlo simulation code (MCNPX) was used to calculate the energy distribution of the proton flux on the Rh target. The activity based on the MCNPX was calculated to be 674.58 mCi. Good agreement between the theoretical and the experimental data of the 103 Pd activity and the activity estimation based on MCNPX calculation was observed. This study demonstrated that MCNPX provides a suitable tool for the simulation of radionuclide production using proton irradiation

Objective: To evaluate the influence of 103 Pd radioactive stent on apoptosis and its relative genes bcl-2 and bax in injured vascular media smooth muscle cells of rabbit abdominal arteries and to investigate the mechanism of 103 Pd radioactive stent for preventing restenosis after angioplasty. Methods: Fifty male New Zealand rabbits were randomized into stent group and 103 Pd stent group. Each group was subdivided into 5 sub-groups. Control group was set up. The study arteries were harvested at 3, 7, 14, 28 and 56 d after stenting and the pathomorphology, apoptosis analysis and in situ hybridization were performed to evaluate the expression of bcl-2 and bax mRNA. Results: The severity of the restenosis in 103 Pd stent group was less than that of stent group. It was most obvious at the 56th day (P 103 Pd stent group had much more apoptosis of vascular smooth muscle cells than stent group did and reached the peak at the 7th day, (14.72±0.53)% vs (12.42±1.13)% (P 103 Pd stent group was much lower than that of stent group at 3 to 28 d. The difference was most obvious at the 28th day after stenting, (18.43± 0.67)% vs (21.55±0.93)% (P 103 Pd stent group was higher than that of stent group, the peak was at the 7th day, (11.17±0.94)% vs (9.30±1.01)%. The ratio of bcl-2/bax in 103 Pd stent group was much lower than that of stent group at 3 to 28 d. Linear correlation analysis showed that there was significant negative correlation between bcl-2 mRNA and apoptosis. Between bax mRNA and apoptosis, the positive correlation was found (P 103 Pd radioactive stent induced more significant apoptosis in vascular media smooth muscle cells by promoting the expression of apoptosis related genes and relieved the expanding of restenosis

Full Text Available The epithelial ovarian carcinoma is one of the most fatal gynecological cancers. Etoposide is used in treating platinum-resistant ovarian cancer. Sodium hyaluronate is a substance that binds to the CD44 receptors overexpressed in SK-OV-3 cells of epithelial ovarian carcinoma. The aim of the present work was to study the cytotoxicity effect of hyaluronate targeted solid lipid nanoparticles (SLNs of etoposide on SK-OV-3 cells. The cytotoxicity of the targeted and nontargeted SLNs of etoposide was compared to free drug on the SK-OV-3 cells by MTT assay method. The cellular uptake of the targeted and nontargeted nanoparticles containing sodium fluorescein was also studied. The difference of cell vitality between nontargeted nanoparticles and also targeted nanoparticles with free drug was significant. Targeted nanoparticles also caused more toxicity than nontargeted nanoparticles (P<0.05. After 4 hours of incubating, the fluorescence was remarkably higher in the cells treated by targeted SLNs rather than nontargeted ones, and there was no observable fluorescence in cells incubated with pure sodium fluorescein. Hyaluronate targeted SLNs containing etoposide increased the cytotoxicity of etoposide on SK-OV-3 cells which may be a worthwhile potential method for reducing the prescribed dose and systemic side effects of this drug in epithelial ovarian carcinoma.

Generator separation of 103Ru//sup 103m/Rh

International Nuclear Information System (INIS)

Epperson, C.E.

1975-01-01

A generator for producing carrier-free Rh-103m was developed using a liquid extraction technique. Initially, Ru-103 chloride was converted to the sulfate by moderate fuming for 80 minutes in 1:1 sulfuric acid. The Ru-103 was then brought to its highest oxidation state with 0.2 N ceric sulfate. Ru-103 tetroxide was removed from an aqueous equilibrium solution of Ru-103/Rh-103m by three one-minute extractions into CCl 4 . The Rh-103m daughter was not extracted under these conditions. Yields of Rh-103m exceeded 90 percent theoretical. The Ru-103 removed by CCl 4 could be recovered by two hours of back-extraction into 2 M sulfuric acid containing 5 mg of sodium sulfite. A cyclic extraction system was made possible by employing sulfate media. Equilibrium Ru-103 could be repeatedly extracted and recovered, thereby producing a ''generator'' system for the production of Rh-103m. Ru-103 chloride can be converted to the sulfate and then stored for at least 38 days prior to extraction. By performing the fuming step whenever convenient, the time required to perform an extraction separation was reduced to 15 minutes. Prior treatment of glassware surfaces with dilute sulfuric acid prevented Ru-103 glass adsorption losses and made glassware much easier to decontaminate. Off-the-shelf reagent-grade CCl 4 could be used without further purification. Efforts to separate Rh-103m from Ru-103 by chromatography techniques were unsuccessful

The impact of a dedicated Science-Technology-Society (STS) course on student knowledge of STS content

Science.gov (United States)

Barron, Paul E.

In the last half century, public awareness of issues such as population growth, environmental pollution and the threat of nuclear war has pressured science education to reform to increase student social responsibility. The emerging Science-Technology-Society (STS) movement addressed these concerns by developing numerous strategies and curricula. Considerable diagnostic research has been conducted on student knowledge of the nature of science, but not on the wider scope of STS content (e.g., the nature of science and technology and their interactions with society). However, researchers have not widely studied the impact of comprehensive STS curricula on students' knowledge of STS content nor the nature of STS teaching practice that influenced this knowledge gain. This study examined student success and teacher performance in a special STS course in Ontario, Canada. Research questions focused on the STS content knowledge gain by students completing this course and the impact of the STS teachers' teaching practices on this knowledge gain. Student data were collected using pre-course and post-course assessments of students' STS content knowledge. Teacher data were obtained using semi-structured interviews, classroom observations and videotapes. Statistical analysis indicated that, after completing the STS course, students significantly increased their STS content knowledge as measured by the Views on Science Technology Society instrument. Gender and academic achievement had no significant impact on this knowledge gain, implying that this course, as taught by these teachers, could appeal to a wide range of students as a general education course. The second part of the study indicated that detailed research is needed on the relationship between STS teaching practice and student STS content knowledge gain. The small sample size prevents generalizations but initial indications show that factors such constructivist teaching practices and strong teacher STS content knowledge

Production of 103mRh for cancer therapy

International Nuclear Information System (INIS)

Skarnemark, G.; Oedegaard-Jensen, A.; Bernhardt, P.

2009-01-01

Radioactive nuclides that emit charged particles with short range are of great interest for internal radiotherapy of small tumors or even single cancer cells. Such therapy uses radio-labelled molecules that find cancer cells and attach to them. When the radionuclide decays it destroys the cancer cell but does not affect the surrounding healthy tissue. Internal radiotherapy may be a complement to surgery, chemotherapy or external irradiation. For larger tumors it is possible to use β-emitters like 90 Y but for small tumors the required short range limits the choice of radio-nuclides to emitters of alpha-particles or low energy electrons, e.g., Auger electrons. A promising α-emitter is 211 At that has undergone laboratory and clinical tests. An example of the other decay mode is the low energy electron emitter 103m Rh. A study performed by BERNHARDT et al. showed that this nuclide has very favorable properties: low electron energy, suitable half-life (56 min) and a low photon/electron ratio (p/e = 0.04). It has also the advantage that it can be produced via a generator containing either 103 Ru or 103 Pd. (author)

Full Text Available Resumo: Estudou-se o tecido germinativo ovariano do peixe Melanotaenia boesemani. Por meio de análises morfológicas das gônadas, realizadas após a confecção de lâminas histológicas elaboradas em parafina e coradas com hematoxilina-eosina, foram descritos os tipos celulares encontrados e realizada a classificação do estádio de maturidade dos peixes. Macroscopicamente, foi identificado que a referida espécie possui ovário único, arredondado e, na fase observada, amarelado, localizado na parte látero-anterior da cavidade celomática. As fêmeas analisadas foram classificadas na escala de desenvolvimento gonadal como maduro/em reprodução. A presença de folículos vazios e marcas de desova nas lamelas ovulígeras mostrou-se evidente. Nos ovócitos vitelogênicos deste peixe, foi constatada a presença de filamentos de adesão ovocitária ancorados à zona pelúcida. Os ovários apresentaram aspecto morfológico geral semelhante ao de outros peixes teleósteos. Seu tipo de desova foi classificado como intermitente e o padrão de desenvolvimento de ovócitos, como assincrônico.

A possible in vivo generator 103Pd/103mRh-Recoil considerations

International Nuclear Information System (INIS)

Rooyen, Johann van; Szucs, Zoltan; Rijn Zeevaart, Jan

2008-01-01

The use of Auger emitters as potential radiopharmaceuticals is increasingly investigated. One such radionuclide of interest is 103m Rh. This can be produced from 103 Ru or from 103 Pd in an in vivo generator. A potential problem with this concept is the recoil of the 103m Rh out of the carrier molecule and even out of the target cell. In order to determine whether this would happen in the 103 Pd/ 103m Rh case calculations were done to prove that this does not happen. From theoretical considerations it seems that the 103 Pd/ 103m Rh in vivo generator system would be possible

2009-01-01

To describe characteristics of odontogenic cysts in a Mexican population. A retrospective study of 103 odontogenic cysts in 86 patients was done. The data were obtained from files of the Pathology Department of a General Hospital. We observed a frequency of the 8.13 % of odontogenic cysts (103) in 1266 pathological studies. The dentigerous cyst 56 % and odontogenic keratocyst 33 % were the most common odontogenic cysts. Sixty one percent of the cysts appeared in the second and third decades of life. In 71 cysts, 42 % appeared in the posterior region jaw, 29 % in the anterior region of the maxilla and 21 % in the posterior region of the maxilla. A 6.7 % developed a recurrence after treatment and a case of keratocyst of posterior region of the maxilla was associated with epidermoid carcinoma. The study included three women with the syndrome of carcinoma of the basal cell nevus, who presented multiple keratocysts. The dentigerous cysts and odontogenic keratocysts were the most frequent odontogenic cysts. They appeared mainly in the second and third decades of life.

Highlights: → We report the cyclotron production of 103-palladium via 103 Rh(p,n) 103 Pd reaction. → 103 Pd was absorbed on resin beads for brachytherapy seed preparation. → The optimum absorption of 103 Pd in resin was achieved at 0.5 M HCl. → Version 5 of MCNP code was employed to model a new 103 Pd brachytherapy seed. - Abstract: In this study, design and fabrication of 103 Pd brachytherapy seed was investigated. The excitation functions of 103 Rh(p,n) 103 Pd and 103 Rh(d,2n) 103 Pd reactions were calculated using EMPIRE (version 3.1 Rivoli), ALICE/ASH and TALYS-1.2 codes, the TENDL-2010 database and compared with the published data. Production of 103 Pd was done via 103 Rh(p,n) 103 Pd nuclear reaction. The target was bombarded with 18 MeV protons at 200 μA beam current for 15 h. After irradiation and radiochemical separation of the electroplated rhodium target, the optimum condition for absorption of 103 Pd into Amberlite (registered) IR-93 resin was achieved at 0.5 M HCl. Version 5 of the (MCNP) Monte Carlo radiation transport code was employed to calculate the dosimetric parameters around the 103 Pd brachytherapy seed. Finally the calculated results were compared with published results for other commercial sources.

We experimentally demonstrate C-band 2 × 56 Gb/s pulse-amplitude modulation (PAM)-4 signal transmission over 100 km standard single-mode fiber (SSMF) using 18 GHz direct-modulated lasers (DMLs) and direct detection, without inline optical amplifier. A delay interferometer (DI) at the transmitter side is used to extend the transmission reach from 40 to 100 km. A digital Volterra filter at the receiver side is used to mitigate the nonlinear distortions. We obtain an average bit error ratio (BER) of 1.5 × 10(-3) for 2 × 56 Gb/s PAM-4 signal after 100 km SSMF transmission at the optimal input power, which is below the 7% forward error correction (FEC) threshold (3.8 × 10(-3)).

The Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) Transcatheter Valve Therapy (TVT) Registry has been a joint initiative of the STS and the ACC in concert with multiple stakeholders. The TVT Registry has important information regarding patient selection, delivery of care, science, education, and research in the field of structural valvular heart disease. This report provides an overview on current U.S. TVT practice and trends. The emphasis is on demographics, in-hospital procedural characteristics, and outcomes of patients having transcatheter aortic valve replacement (TAVR) performed at 348 U.S. centers. The TVT Registry captured 26,414 TAVR procedures as of December 31, 2014. Temporal trends between 2012 and 2013 versus 2014 were compared. Comparison of the 2 time periods reveals that TAVR patients remain elderly (mean age 82 years), with multiple comorbidities, reflected by a high mean STS predicted risk of mortality (STS PROM) for surgical valve replacement (8.34%), were highly symptomatic (New York Heart Association functional class III/IV in 82.5%), frail (slow 5-m walk test in 81.6%), and have poor self-reported health status (median baseline Kansas City Cardiomyopathy Questionnaire score of 39.1). Procedure performance is changing, with an increased use of moderate sedation (from 1.6% to 5.1%) and increase in femoral access using percutaneous techniques (66.8% in 2014). Vascular complication rates are decreasing (from 5.6% to 4.2%), whereas site-reported stroke rates remain stable at 2.2%. The TVT Registry provides important information on characteristics and outcomes of TAVR in contemporary U.S. clinical practice. It can be used to identify trends in practice and opportunities for quality improvement.

Expressão gênica em ovócitos suínos de diferentes classificações morfológicas

Full Text Available A produção in vitro de embriões suínos tem alcançado resultados insatisfatórios: ovócitos maturados in vivo produzem uma porcentagem maior de embriões em relação aos maturados in vitro. O sucesso da maturação in vitro está diretamente relacionado com a competência ovocitária. Somente ovócitos competentes são capazes de serem fecundados e terem desenvolvimento embrionário normal. A competência ovocitária pode ser avaliada por vários parâmetros. Recentemente têm sido utilizados como parâmetro os estudos da expressão de genes associados com a competência. O presente trabalho teve por objetivo avaliar diferenças na expressão dos genes BMP15, RYBP, MATER e ZAR1 em ovócitos imaturos de diferentes classes morfológicas, sendo elas: 1, 2, 3 e 4, com a finalidade de proporcionar importantes marcadores moleculares relacionados com a capacidade ovocitária. O RNA total dos ovócitos foi extraído e utilizado como molde para a síntese da primeira fita de cDNA. Os resultados da expressão gênica foram analisados utilizando-se modelo misto, considerando os dados de expressão gênica variável dependente e as classes ovocitárias variáveis independentes. Os genes BMP15, ZAR1 e RYBP apresentaram expressão semelhante nas classes ovocitárias 1, 2 e 3; somente a categoria 4 diferiu na expressão desses genes (P0,05. A técnica de RT-qPCR foi eficiente para detecção desses transcritos em ovócitos de diferentes classes. No entanto, para melhor entendimento do envolvimento desses transcritos na aquisição da competência ovocitária, são necessários mais estudos avaliando ovócitos de diferentes classes morfológicas, em diferentes fases de desenvolvimento, e implicação de outros genes envolvidos com a competência ovocitária.

Kasper Rossing

Full Text Available Biomarker discovery and new insights into the pathophysiology of heart failure with reduced ejection fraction (HFrEF may emerge from recent advances in high-throughput urinary proteomics. This could lead to improved diagnosis, risk stratification and management of HFrEF.Urine samples were analyzed by on-line capillary electrophoresis coupled to electrospray ionization micro time-of-flight mass spectrometry (CE-MS to generate individual urinary proteome profiles. In an initial biomarker discovery cohort, analysis of urinary proteome profiles from 33 HFrEF patients and 29 age- and sex-matched individuals without HFrEF resulted in identification of 103 peptides that were significantly differentially excreted in HFrEF. These 103 peptides were used to establish the support vector machine-based HFrEF classifier HFrEF103. In a subsequent validation cohort, HFrEF103 very accurately (area under the curve, AUC = 0.972 discriminated between HFrEF patients (N = 94, sensitivity = 93.6% and control individuals with and without impaired renal function and hypertension (N = 552, specificity = 92.9%. Interestingly, HFrEF103 showed low sensitivity (12.6% in individuals with diastolic left ventricular dysfunction (N = 176. The HFrEF-related peptide biomarkers mainly included fragments of fibrillar type I and III collagen but also, e.g., of fibrinogen beta and alpha-1-antitrypsin.CE-MS based urine proteome analysis served as a sensitive tool to determine a vast array of HFrEF-related urinary peptide biomarkers which might help improving our understanding and diagnosis of heart failure.

1978-01-01

103 Pd separated from metal rhodium irradiated with deuterons has been used without a carrier for sup( 03m)Rh generator The generator of sup(103m)Rh is a column 6mm in diameter filled with an anionite in Cl - form (Dowex-2,8,200-400 mesh) with an adsorbed parent isotope of 103 Pd. As a result of its decay, a 103 Rh daughter isotope is accumulated, which can be washed out from the generator from time to time with a corresponding solution. To prepare the generator, 0.5g of the resin with an adsorbed 103 Pd is charged into the column containing 1g of the same resin. Washing out with 2N HCl yields more than 90% of sup(103m)Rh with a radionuclide purity of more than 99.99%

In May of 2002, three cracks were found in the downstream flowliner at the gimbal joint in the LH2 feedline at the interface with the Low Pressure Fuel Turbopump (LPFP) of Space Shuttle Main Engine (SSME) #1 of Orbiter OV-104. Subsequent inspections of the feedline flowliners in the other orbiters revealed the existence of 8 additional cracks. No cracks were found in the LO2 feedline flowliners. A solution to the cracking problem was developed and implemented on all orbiters. The solution included weld repair of all detectable cracks and the polishing of all slot edges to remove manufacturing discrepancies that could initiate new cracks. Using the results of a fracture mechanics analysis with a scatter factor of 4 on the predicted fatigue life, the orbiters were cleared for return to flight with a one-flight rationale requiring inspections after each flight. OV-104 flew mission STS-112 and OV-105 flew mission STS-113. The post-flight inspections did not find any cracks in the repaired flowliners. At the request of the Orbiter Program, the NESC conducted an assessment of the Orbiter LH2 Feedline Flowliner cracking problem with a team of subject matter experts from throughout NASA.

STS, symmetry and post-truth.

Science.gov (United States)

Lynch, Michael

2017-08-01

This essay takes up a series of questions about the connection between 'symmetry' in Science and Technology Studies (STS) and 'post-truth' in contemporary politics. A recent editorial in this journal by Sergio Sismondo argues that current discussions of 'post-truth' have little to do with conceptions of 'symmetry' or with concerns about 'epistemic democracy' in STS, while others, such as Steve Fuller and Harry Collins, insist that there are such connections. The present essay discusses a series of questions about the meaning of 'post-truth' and 'symmetry', and the connections of those concepts to each other and to 'epistemic democracy'. The essay ends with a series of other questions about STS and contemporary politics, and an invitation to further discussions.

Discovery and Development of the Aryl O-Sulfamate Pharmacophore for Oncology and Women's Health.

Science.gov (United States)

Thomas, Mark P; Potter, Barry V L

2015-10-08

In 1994, following work from this laboratory, it was reported that estrone-3-O-sulfamate irreversibly inhibits a new potential hormone-dependent cancer target steroid sulfatase (STS). Subsequent drug discovery projects were initiated to develop the core aryl O-sulfamate pharmacophore that, over some 20 years, have led to steroidal and nonsteroidal drugs in numerous preclinical and clinical trials, with promising results in oncology and women's health, including endometriosis. Drugs have been designed to inhibit STS, e.g., Irosustat, as innovative dual-targeting aromatase-steroid sulfatase inhibitors (DASIs) and as multitargeting agents for hormone-independent tumors, such as the steroidal STX140 and nonsteroidal counterparts, acting inter alia through microtubule disruption. The aryl sulfamate pharmacophore is highly versatile, operating via three distinct mechanisms of action, and imbues attractive pharmaceutical properties. This Perspective gives a personal view of the work leading both to the therapeutic concepts and these drugs, their current status, and how they might develop in the future.

We have assembled a high-resolution physical map of human chromosome 13 DNA (approximately 114 Mb) from hybridization, PCR, and FISH mapping data using a specifically designed set of computer programs. Although the mapping of 13p is limited, 13q (approximately 98 Mb) is covered by an almost continuous contig of 736 YACs aligned to 597 contigs of cosmids. Of a total of 10,789 cosmids initially selected from a chromosome 13-specific cosmid library (16,896 colonies) using inter-Alu PCR probes from the YACs and probes for markers mapped to chromosome 13, 511 were assembled in contigs that were established from cross-hybridization relationships between the cosmids. The 13q YAC-cosmid map was annotated with 655 sequence tagged sites (STSs) with an average spacing of 1 STS per 150 kb. This set of STSs, each identified by a D number and cytogenetic location, includes database markers (198), expressed sequence tags (93), and STSs generated by sequencing of the ends of cosmid inserts (364). Additional annotation has been provided by positioning 197 cosmids mapped by FISH on 13q. The final (comprehensive) map, a list of STS primers, and raw data used in map assembly are available at our Web site (genome1.ccc.columbia.edu/ approximately genome/) and can serve as a resource to facilitate accurate localization of additional markers, provide substrates for sequencing, and assist in the discovery of chromosome 13 genes associated with hereditary diseases.

2018-03-01

Full Text Available The use of graphene to target and eliminate cancer stem cells (CSCs is an alternative approach to conventional chemotherapy. We show the biomolecule-mediated synthesis of reduced graphene oxide–silver nanoparticle nanocomposites (rGO–Ag using R-phycoerythrin (RPE; the resulting RPE–rGO–Ag was evaluated in human ovarian cancer cells and ovarian cancer stem cells (OvCSCs. The synthesized RPE–rGO–Ag nanocomposite (referred to as rGO–Ag was characterized using various analytical techniques. rGO–Ag showed significant toxicity towards both ovarian cancer cells and OvCSCs. After 3 weeks of incubating OvCSCs with rGO–Ag, the number of A2780 and ALDH+CD133+ colonies was significantly reduced. rGO–Ag was toxic to OvCSCs and reduced cell viability by mediating the generation of reactive oxygen species, leakage of lactate dehydrogenase, reduced mitochondrial membrane potential, and enhanced expression of apoptotic genes, leading to mitochondrial dysfunction and possibly triggering apoptosis. rGO–Ag showed significant cytotoxic potential towards highly tumorigenic ALDH+CD133+ cells. The combination of rGO–Ag and salinomycin induced 5-fold higher levels of apoptosis than each treatment alone. A combination of rGO–Ag and salinomycin at very low concentrations may be suitable for selectively killing OvCSCs and sensitizing tumor cells. rGO–Ag may be a novel nano-therapeutic molecule for specific targeting of highly tumorigenic ALDH+CD133+ cells and eliminating CSCs. This study highlights the potential for targeted therapy of tumor-initiating cells.

(Abstract only) Among the 1000 known cataclysmic variables, only one appears to belong to the "Galactic halo"-the Population II stars. We report round-the-world photometry of this star (OV Boo) during March-April 2017, when it staged its first certified dwarf-nova outburst. The star is remarkable for its short binary period (66 minutes), high proper motion, metal-poor composition, substellar secondary, sharp white-dwarf eclipses, and nonradial pulsations. Something for everybody - and it even had the good manners to erupt in northern springtime, when it transits near local midnight. Move over, SS Cyg and WZ Sge; there's a new celebrity in town!

Recoil effect on β-decaying in vivo generators, interpreted for 103Pd/103mRh

International Nuclear Information System (INIS)

Szucs, Zoltan; Rooyen, Johann van; Zeevaart, Jan Rijn

2009-01-01

The use of Auger emitters as potential radiopharmaceuticals is being increasingly investigated. One of the radionuclides of interest is 103m Rh, which can be produced from 103 Ru or 103 Pd in an in vivo generator. A potential problem, however, is the recoil of the 103m Rh out of the carrier molecule and even out of the target cell. In order to determine the likelihood of this happening in the 103 Pd/ 103m Rh, case calculations were made to prove that this does not happen. The equations were generalised for all radionuclides with an atomic mass of 10-240 as a tool for determining the recoil threshold of any β-emitting radionuclide.

The results for eight replications of the solvent extraction and purification procedures were /sup 103m/Rh yield, 100.9 +- 2.1% and 103 Ru contamination, 0.0%. The use of sodium hypochlorite as the oxidizing agent eliminated the need for fuming with 1:1 H 2 SO 4 to eliminate chlorides as was required when ceric sulfate was used as the oxidizing agent. The optimum pH for extraction of RuO 4 into CCl 4 was determined to be in the range 6.5 to 7.5. A boiling procedure was used to purify the extracted aqueous solution of /sup 103m/Rh

PROMOTING TOURIST DESTINATIONS THROUGH SPORT EVENTS. THE CASE OF BRAŞOV

Directory of Open Access Journals (Sweden)

Adina Nicoleta CANDREA

2010-12-01

Full Text Available Sport event tourism is a huge and growing global industry with important economic implications for both the sport, the event and the impact of travel and tourism related benefits on host destinations. A primary function of a sport event is to provide the host community with an opportunity to secure high prominence in the tourism market place. However, international or regional prominence may be gained with significant social and environmental costs. Hosting sport events has been a focus of destination marketers as a strategy to enhance its destination image and differentiate its tourism products. Communities are attracted to hosting sport events to draw marketing benefits that will contribute to the success of the destination in the long run by creating awareness, improving their image with visitors and attracting tourism business to generate future inbound travel. As such, destination images can be influenced by the hosting of a sport event and the attributes associated with this event. The purpose of this paper is to outline the role of sport event tourism in the promotion of tourist destinations. A case study has been chosen in order to illustrate the interdependence between event and destination marketing: Braşov, hosting the winter edition of The European Youth Olympic Festival in 2013. The paper includes a series of recommendations for destination managers in order to maximise the benefits of this event and take this opportunity to promote Braşov on the international market.

Recent developments concerning the discovery of elements 101-111

International Nuclear Information System (INIS)

Greenwood, N.N.

1997-01-01

The addition of eleven new elements (Z=101-111) to the Periodic Table during the past 40 years has involved outstanding feats of intellectual and experimental virtuosity. Some of the discoveries have been widely accepted but others have been hotly contested and this has led to distressingly persistent disagreements concerning priority. For this reason IUPAC and IUPAP (Physics) set up a joint Transfermium Working Group (TWG) in 1987 to recommend ''the criteria that must be satisfied for the discovery of a new element to be recognised'' and to apply these criteria to questions of priority in the discovery of the transfermium elements (Z > 100). After several years of detailed work the TWG published their extensive studies and conclusions, and these have been accepted by both IUPAC and IUPAP. Many subtle and difficult points were considered and these will be discussed in this lecture together with the TWG's final recommendations, which have been widely though not universally accepted by the scientific community. The separate question of names and symbols for the new elements with Z > 103 has not yet been finally resolved but will be briefly discussed. (Author)

Dattoli, M.J.; Wallner, K.E.; Cash, J.C.; Ross, R.E.; Koval, J.M.; Sorace, R.A.

1997-01-01

Purpose: To evaluate the efficacy of Pd-103 brachytherapy as sole modality for patients having clinical T1/T2 prostate carcinomas Materials and Methods: The initial 103 consecutive patients treated at our hospital are available for biochemical failure and toxicity data following Pd-103 brachytherapy. Minimum peripheral target dose of 11,500cGy (median) was prescribed. Follow-up range: 4-6 years (56 months median). Mean pre-treatment PSA = 11.7ng/ml. All patients have been followed in prospective fashion with respect to PSA response, clinical evidence of disease progression and complications. Criteria for biochemical failure was relatively strict, and was analyzed using PSA>1.0. Patients whose PSA was still decreasing at last follow-up were censored at that time. Freedom from failure rates were calculated by the method of Kaplan and Meier. Differences between groups were determined by the Log-rank method. Sexual potency was defined as the ability to attain and maintain an erection sufficient for intercourse. Results: Actuarial freedom from biochemical failure at 6 years after treatment is 68%. Toxicity has been low with no patient developing rectal ulceration or incontinence (despite 16 pts having prior TURP). The impotency rate is 12%. Of the 33 pts with a post treatment PSA >1.0, 29 pts actually had one or more adverse features determined to be PSA>10 (26 pts), Gleason's score ≥ 7 (5 pts), AJC clinical stage≥T2b (10 pts). Mean pre-treatment PSA's of the 33 failures = 18.3ng/ml. For the 74 pts without high risk features, the actuarial 6 years biochemical freedom from progression rate using PSA<1.0 as an endpoint for success is 93%. Conclusion: This biochemical freedom from progression rate compares favorably to other modalities and supports the use of Pd-103 brachytherapy as sole modality in properly selected patients. Morbidity has been relatively low. Pd-103 implant alone is currently being used in patients having PSA<10, Gleason's score<7, and clinical stage

Purpose: The aim of this study was to assess the performance measurements of the new PET/CT system Discovery-600 (D-600, GEMS, Milwaukee, WI). Methods: Performance measures were obtained with the National Electrical Manufacturers Association (NEMA) NU 2-2007 procedures. Results: The transverse (axial) spatial resolution FWHMs were 4.9 (5.6) mm and 5.6 (6.4) mm at 1 and 10 cm off axis, respectively. The sensitivity (average at 0 and 10 cm) was 9.6 cps/kBq. The scatter fraction was 36.6% (low energy threshold: 425 keV). The NEC peak rate (k=1) was 75.2 kcps at 12.9 kBq/cc. The hot contrasts for 10, 13, 17, and 22 mm spheres were 41%, 51%, 62%, and 73% and the cold contrasts for 28 and 37 mm spheres were 68% and 72%. Conclusions: The Discovery-600 has good performance for the NEMA NU 2-2007 parameters, particularly in improved sensitivity compared to the scanners of the same Discovery family, D-ST and D-STE.

L-Area STS MTR/NRU/NRX Grapple Assembly Closure Mechanics Review

International Nuclear Information System (INIS)

Huizenga, D. J.

2016-01-01

A review of the closure mechanics associated with the Shielded Transfer System (STS) MTR/NRU/NRX grapple assembly utilized at the Savannah River Site (SRS) was performed. This review was prompted by an operational event which occurred at the Canadian Nuclear Laboratories (CNL) utilizing a DTS-XL grapple assembly which is essentially identical to the STS MTR/NRU/NRX grapple assembly used at the SRS. The CNL operational event occurred when a NRU/NRX fuel basket containing spent nuclear fuel assemblies was inadvertently released by the DTS-XL grapple assembly during a transfer. The SM review of the STS MTR/NRU/NRX grapple assembly will examine the operational aspects of the STS and the engineered features of the STS which prevent such an event at the SRS. The design requirements for the STS NRU/NRX modifications and the overall layout of the STS are provided in other documents.

The development of STS payload environmental engineering standards

Science.gov (United States)

Bangs, W. F.

1982-01-01

The presently reported effort to provide a single set of standards for the design, analysis and testing of Space Transportation System (STS) payloads throughout the NASA organization must be viewed as essentially experimental, since the concept of incorporating the diverse opinions and experiences of several separate field research centers may in retrospect be judged too ambitious or perhaps even naive. While each STS payload may have unique characteristics, and the project should formulate its own criteria for environmental design, testing and evaluation, a reference source document providing coordinated standards is expected to minimize the duplication of effort and limit random divergence of practices among the various NASA payload programs. These standards would provide useful information to all potential STS users, and offer a degree of standardization to STS users outside the NASA organization.

2008-01-01

Full Text Available In north India the number of paediatric cases with acquired immunodeficiency syndrome (AIDS is on the rise. Most drug combinations used for treatment of AIDS incorporate nevirapine, resistance to which develops very fast if given singly or because of unplanned interruptions. This paper investigates presence of mutations at codon 103 and codon 215 of the HIV pol gene causing resistance to nevirapine and zidovudine (AZT respectively in 25 children with AIDS. Mutations T215Y and K103N were detected by a nested cum amplification refractory mutation system polymerase chain reaction (ARMS PCR and the results were confirmed by direct sequencing in five randomly selected cases. Nineteen patients had received nevirapine containing regimen and six were drug naive. Mutation K103N was observed in 56% (14/25 of the children while mutation T215Y was found in none. Two of the six drug naοve children also showed K103N mutation. Thus, Indian children drug naοve or treated with nevirapine containing regimens show a high rate of mutation conferring resistance to nevirapine which calls for a judicious use of nevirapine both in antenatal and postnatal setting.

Full Text Available When I learned about a concerted campaign against Australian vaccination critics, I decided to intervene in the debate. As a result, some proponents of vaccination turned on me, making abusive comments and complaining to university officials. At several points in this experience, I had to make choices about how to intervene or respond. STS perspectives offered valuable insights for understanding the dynamics of the controversy but provided little guidance for making decisions. Some reasons are offered for why STS lacks tools for guiding practical action in such situations.

2012-04-01

Full Text Available The ovarian remnant syndrome (ORS is an iatrogenic disorder in bitches and queens, which is characterized by recurrence of estrus following surgical spay, due to the presence of a piece of ovarian tissue within the abdominal cavity. In most cases, the remnant ovary is found in the right ovarian pedicle, due to its topographic position, deeper and more cranial than the left ovary. The main clinical signs of ORS in small animals are the heat behavior and the presence of vaginal swelling/secretion, especially in canines. The diagnosis should be performed by means of vaginal cytology when attraction of males is detected, serum estrogen and progesterone levels and/or by challenging test with GnRH or hCG administration. However, vaginal citology is the most suitable and less expensive diagnostic tool. Nowadays the treatment of choice is a new laparotomy or laparoscopy, followed by removal of the remnant ovarian tissue. The surgical treatment has more chances of success if it is performed in the diestrus (i.e., between 15 and 60 days after the detection of attraction of males. Furthermore, a careful and accurate surgical procedure aided by advanced visualization techniques during ovariohysterectomy or ovariectomy is the best way to prevent ORS in companion animals. A síndrome do ovário remanescente (SOR é um distúrbio iatrogênico em cadelas e gatas caracterizado pelo retorno do estro após contracepção cirúrgica devido à presença de fragmento de tecido ovariano na cavidade abdominal. Frequentemente, o ovário remanescente está situado no pedículo ovariano direito, sobretudo devido a sua posição topográfica mais profunda e cranial em comparação ao ovário esquerdo. Os principais sinais clínicos de SOR em pequenos animais são cio e presença de edemaciamento/secreção vulvar/vaginal, especialmente em caninos. O diagnóstico deve ser realizado por meio de citologia vaginal quando detecta-se o interesse dos machos pela cópula com a f

1992-01-01

Fab' fragments of the monoclonal antibody OV-TL 3, that recognizes an ovarian carcinoma-associated antigen (OA3), were labelled with 99 Tc m using D-glucarate as a ligand. Twenty patients suspected of having primary or recurrent ovarian cancer received intravenously 1 mg of the Fab' labelled with 740 MBq 99 Tc m . Both planar and single photon emission computed tomographic (SPECT) scintigraphy were performed up to 30 h after intravenous infusion. Imaging results were compared with X-ray computed tomography (CT), ultrasonography (US) and CA 125 serum level. Blood clearance was fast (t 1/2 of 9.5 h). Thirty-seven per cent of the injected dose (% ID) was excreted in the urine within the first 24 h, whereas 7% ID was excreted in the 24 h faeces. In one patient with an OA3 negative ovarian carcinoma, radioimmunoscintigraphy (RIS) did not visualize the tumour. In two other patients a benign ovarian cyst was found, also showing no elevated uptake. In 13 out of 17 patients ovarian cancer lesions were detected with RIS, whereas CT and US detected lesions in, respectively, 15 and 12 patients. Of 36 surgically defined tumour deposits larger than 1 cm in diameter, 53% were detected and localized with RIS, whereas CT and US detected 61 and 40%, respectively. Radioimmunoscintigraphy with 99 Tc m -OV-TL 3 Fab' is less distressing for the patients but the overall imaging performance is not improved when compared with 111 In-OV-TL 3 F(ab') 2 . (Author)

Full Text Available RESUMO: A leptina, uma citocina produzida pelas células adiposas, é alvo da comunidade científica por acreditarem que ela apresente impacto sobre a reprodução dos animais promovendo a puberdade, foliculogênese e oogênese, ciclo estral e auxiliando na fecundação. A compreensão dos mecanismos que controlam a atividade reprodutiva de preás (Galea spixii possui papel relevante para a preservação da espécie. Desta forma, o presente trabalho propôs analisar a imunolocalização dos receptores de leptina (Ob-R no ovário de preás. Coletaram-se os ovários de 20 fêmeas adultas, não prenhes e saudáveis. As amostras foram fixadas em paraformaldeído a 4% em tampão fosfato, incluídas em parafina e seccionadas para a realização de imunohistoquímica (IHC. As secções foram fotomicrografadas e avaliadas quanto à intensidade da reação. Observou-se forte imunorreação no oócito e nas células da teca, moderada nas células do estroma ovariano e nas células luteínicas grandes e fracamente coradas nas células da granulosa, endoteliais, perivasculares e células luteínicas pequenas. Quando comparado a expressão de receptores ao longo do desenvolvimento folicular foi observado que o oócito e as células da teca se mantiveram com expressão na mesma intensidade. Entretanto, as células da granulosa apresentaram forte marcação nos estádios pré-antrais enquanto que nos folículos antrais apresentou fraca intensidade. Concluímos que em ovários de Galea spixii existe a presença de Ob-R nas principais estruturas do ovário sugerindo que este hormônio desempenhe papel fundamental na reprodução desta espécie.

Alguns estudos sugerem um aumento do risco de neoplasia em pacientes com esclerose sistêmica (ES, mas a associação com neoplasia de ovário, principalmente do subtipo mucinoso, não é comum. Os autores descrevem um caso de cistoadenocarcinoma mucinoso de ovário em uma mulher branca de 52 anos com diagnóstico de ES difusa há seis anos, tratada previamente com D-penicilamina e ciclofosfamida, que procurou o serviço médico com queixa de dor e aumento do volume abdominal há três meses. Ao exame físico apresentava facies esclerodérmica, membros superiores com diminuição da elasticidade e enxerto bitibial em membros inferiores; no abdome havia a presença de uma massa endurecida estendendo-se da região suprapúbica até o epigástrio. Foi realizada laparotomia exploradora onde se encontrou uma massa cística no ovário direito, com peso de 3.300 gramas. Em seguida procedeu-se exérese do tumor com histerectomia total e ooforectomia bilateral. O exame histológico confirmou tratar-se de um cistoadenocarcinoma mucinoso sem invasão de cápsula.Ovarian cancer is the third cause of death among malignant neoplasia in women, and the mucinous cystadenocarcinoma is a malignant neoplasia of the ovarian epithelium, which may achieve great dimensions.

Discovery of cancer common and specific driver gene sets

Science.gov (United States)

2017-01-01

Abstract Cancer is known as a disease mainly caused by gene alterations. Discovery of mutated driver pathways or gene sets is becoming an important step to understand molecular mechanisms of carcinogenesis. However, systematically investigating commonalities and specificities of driver gene sets among multiple cancer types is still a great challenge, but this investigation will undoubtedly benefit deciphering cancers and will be helpful for personalized therapy and precision medicine in cancer treatment. In this study, we propose two optimization models to de novo discover common driver gene sets among multiple cancer types (ComMDP) and specific driver gene sets of one certain or multiple cancer types to other cancers (SpeMDP), respectively. We first apply ComMDP and SpeMDP to simulated data to validate their efficiency. Then, we further apply these methods to 12 cancer types from The Cancer Genome Atlas (TCGA) and obtain several biologically meaningful driver pathways. As examples, we construct a common cancer pathway model for BRCA and OV, infer a complex driver pathway model for BRCA carcinogenesis based on common driver gene sets of BRCA with eight cancer types, and investigate specific driver pathways of the liquid cancer lymphoblastic acute myeloid leukemia (LAML) versus other solid cancer types. In these processes more candidate cancer genes are also found. PMID:28168295

Full Text Available El estudio de la morfometría ovárica está directamente relacionado con sus aplicaciones para analizar e interpretar los hallazgos, en los exámenes ginecológicos de las vacas. Para este trabajo se recolectaron 114 pares de ovarios en frigorífico, clasificados a partir del ancho, grueso, largo, volumen, diámetro del folículo, diámetro y área del cuerpo lúteo. Fue observada una diferencia significativa en el ancho (1,95cm y 1,83cm y el volumen (7,26 mL y 6,23 mL de los ovarios izquierdos y derechos, respectivamente. En cuanto al tamaño y el volumen de los folículos, el diámetro y el área de los cuerpos lúteos, no hubo diferencia relevante. En los lados hubo correlación positiva (p<0,01 entre el volumen del ovario izquierdo y el área del cuerpo lúteo. La presencia de folículos con diámetro igual o superior a 9mm, el cuerpo lúteo de tipo macizo y protruso presente en 43,39% de los 53 ovarios, predominó con relación al tipo cóncavo. De los 84 ovarios con cuerpos lúteos, el 26,20% eran de tipo extrapolado. Se concluye, que la presencia de cuerpo lúteo incluso, en vacas cebú, puede resultar en fallas diagnósticas durante el examen de palpación rectal para estimar la actividad ovárica.

Separation of [Rh-103m]-rhodocene-derivatives from the parent [103Ru]ruthenocen-derivatives and their organ distribution

International Nuclear Information System (INIS)

Wenzel, M.; Wu, Y.

1987-01-01

The radioactive decay of [ 103 Ru]ruthenocene derivatives leads to sup(103m)Rh labelled rhodocinium derivatives, which can be separated by the extraction of a lipophilic solution of the ruthenocen derivate with water. The separation factor sup(103m)Rh/ 103 Ru reaches values of 32:1 Rh 3+ ions are not liberated and extracted. The organ distribution of the sup(103m)Rh labelled rhodocinium derivatives gained from ruthenocene and from N-isopropyl-ruthenocene amphetamine is different from the distribution of the parent ruthenocene compound. The liver and kidney uptake of the rhodocinium-amphetamine is much higher than the uptake with ruthenocene amphetamine. (author)

First haemorheological experiment on NASA space shuttle 'Discovery' STS 51-C: aggregation of red cells.

Science.gov (United States)

Dintenfass, L; Osman, P D; Jedrzejczyk, H

1985-01-01

The 'secret' D.O.D. Mission on flight STS 51-C also carried nearly 100 kg of automated instrumentation of the Australian experiment on aggregation of red cells ("ARC"). The automated Slit-Capillary Photo Viscometer contained blood samples from subjects with history of coronary heart disease, cancer of the colon, insulin-dependent diabetes, etc., as well as normals. The experiment ran for nine hours, according to the program of its microcomputers. When shuttle landed and instrumentation recovered and opened in the presence of NASA quality control officers, it was obvious that experiment was a success. Tentative and preliminary results can be summarized as follows: red cells did not change shape under zero gravity; red cells do aggregate under zero gravity, although the size of aggregates is smaller than on the ground; the morphology of aggregates of red cells appears to be of rouleaux type under zero gravity, notwithstanding the fact that pathological blood was used. These results will have to be confirmed in the future flights. The background and history of development of the project are described, and put into context of our general haemorheological studies.

Cross section measurement for the reaction /sup 103/Rh (n,n') /sup 103m/Rh

International Nuclear Information System (INIS)

Paulsen, A.; Liskien, H.; Vaninbroukx, R.; Widera, R.

1980-01-01

The excitation function for the reaction /sup 103/Rh (n,n') /sup 103m/Rh was measured by the activation technique from 0.2 to 6.1 MeV in 0.1-MeV steps and from 13.0 to 16.7 MeV in 1-MeV steps. This excitation function is normalized through an absolute measurement at 1.8 MeV. This measurement is based on n-p scattering for neutron flux determination and on liquid scintillation counting of /sup 103m/Rh separated from /sup 103/Pd solutions for the activity determination. The total uncertainty of the cross-section results is typically + or -5% above 0.5 MeV (about + or -10% above 13 MeV). Concurrence with existing data is good except below 0.35 MeV, where the present results are considerably higher

Manchang, T K; Ajonina-Ekoti, I; Ndjonka, D; Eisenbarth, A; Achukwi, M D; Renz, A; Brattig, N W; Liebau, E; Breloer, M

2015-05-01

Onchocerca volvulus is a tissue-dwelling, vector-borne nematode parasite of humans and is the causative agent of onchocerciasis or river blindness. Natural infections of BALB/c mice with Litomosoides sigmodontis and of cattle with Onchocerca ochengi were used as models to study the immune responses to O. volvulus-derived recombinant proteins (OvALT-2, OvNLT-1, Ov103 and Ov7). The humoral immune response of O. volvulus-infected humans against OvALT-2, OvNLT-1 and Ov7 revealed pronounced immunoglobulin G (IgG) titres which were, however, significantly lower than against the lysate of O. volvulus adult female worms. Sera derived from patients displaying the hyperreactive form of onchocerciasis showed a uniform trend of higher IgG reactivity both to the single proteins and the O. volvulus lysate. Sera derived from L. sigmodontis-infected mice and from calves exposed to O. ochengi transmission in a hyperendemic area also contained IgM and IgG1 specific for O. volvulus-derived recombinant proteins. These results strongly suggest that L. sigmodontis-specific and O. ochengi-specific immunoglobulins elicited during natural infection of mice and cattle cross-reacted with O. volvulus-derived recombinant antigens. Monitoring O. ochengi-infected calves over a 26-month period, provided a comprehensive kinetic of the humoral response to infection that was strictly correlated with parasite load and occurrence of microfilariae.

Strayer, Richard F.; Hummerick, Mary E.; Richards, Jeffrey T.; McCoy, LaShelle E.; Roberts, Michael S.; Wheller, Raymond M.

2011-01-01

The project reported here provides microbial characterization support to the Waste Management Systems (WMS) element of NASA's Life Support and Habitation Systems (LSHS) program. Conventional microbiological methods were used to detect and enumerate microorganisms in STS Volume F Compartment trash for three shuttle missions: STS 133, 134, and 135. This trash was usually made available within 2 days of landing at KSC. The Volume F bag was weighed, opened and the contents were cataloged and placed into categories: personal hygiene items - inclUding EVA maximum absorbent garments (MAGs) and Elbow packs (daily toilet wipes, etc), drink containers, food waste (and containers), office waste (paper), and packaging materials - plastic film and duct tape. The average wet trash generation rate for the three STS missions was 0.362 % 0.157 kgwet crew 1 d-1 . This was considerably lower and more variable than the average rate for 4 STS missions reported for FY10. Trash subtotals by category: personal hygiene wastes, 56%; drink items, 11 %; food wastes, 18%; office waste, 3%; and plastic film, 12%. These wastes have an abundance of easily biodegraded compounds that can support the growth of microorganisms. Microbial characterization of trash showed that large numbers of bacteria and fungi have taken advantage of this readily available nutrient source to proliferate. Exterior and interior surfaces of plastic film bags containing trash were sampled and counts of cultivatable microbes were generally low and mostly occurred on trash bundles within the exterior trash bags. Personal hygiene wastes, drink containers, and food wastes and packaging all contained high levels of, mostly, aerobic heterotrophic bacteria and lower levels of yeasts and molds. Isolates from plate count media were obtained and identified .and were mostly aerobic heterotrophs with some facultative anaerobes. These are usually considered common environmental isolates on Earth. However, several pathogens were also

STS-99 workers carry new Master Events Controller to Endeavour

Science.gov (United States)

2000-01-01

Workers carry the replacement Enhanced Main Events Controller (E- MEC) to Shuttle Endeavour at Launch Pad 39A for installation in the aft compartment of the payload bay. The original E-MEC became suspect during the Jan. 31 launch countdown and mission STS-99 was delayed when NASA managers decided to replace it. Each Shuttle carries two enhanced master events controllers (E-MECs), which provide relays for onboard flight computers to send signals to arm and fire pyrotechnics that separate the solid rockets and external tank during assent. Both E-MECs are needed for the Shuttle to be cleared for flight. Currently Endeavour and Columbia are the only two orbiters with the E-MECs. Built by Rockwell's Satellite Space Electronics Division, Anaheim, Calif., each unit weighs 65 pounds and is approximately 20 inches long, 13 inches wide and 8 inches tall. Previously, three Shuttle flights have been scrubbed or delayed due to faulty MECs: STS-73, STS-49 and STS-41-D. The next scheduled date for launch of STS-99 is Feb. 11 at 12:30 p.m. EST.

Forecast the Impact of Bucharest – Braşov Highway on the Economic and Functional Structure of Human Settlements in Ilfov County

Directory of Open Access Journals (Sweden)

PETRONELA NOVĂCESCU

2011-01-01

Full Text Available One of the most publicized issues concerning the infrastructure of Romania is the Bucharest-Braşov highway. The long-awaited project aims to streamline the traffic between the Capital and the central part of the country, representing the central area of the Pan - European Road Corridor IV. The length of the highway on the territory of Ilfov County is 31 km, representing 17% of the total length of Bucharest- Braşov highway. The start of the highway will have strong effects on economic structure and on the way the Bucharest Metropolitan Area will work. We can expect an increase in the disparities between the settlements of Ilfov County. This pattern is also observable on the Bucharest-Ploieşti corridor where, in recent years, much of the Ilfov county's economic activities have migrated to the north, especially along that corridor. Besides economic migration, intense residential migration followed the Bucharest – Ploieşti corridor, residents of the Bucharest itself moving out to the north of Ilfov County. Probably, the future Bucharest – Braşov highway will lead to an increased suburbanization and periurbanization, this in turn giving way to the crowding of the area by businesses eager to have access to the highway. This project will likely increase the gap between north and south of Ilfov County. In addition to changes that may occur at the county level, changes will also have an impact on the localities themselves since the areas located near the highway will have an economic and demographic growth rate superior to more remote areas. In this sense, we conducted a comparative analysis between eight settlements of Ilfov county crossed by the Bucharest-Braşov highway in order to assess the impact. This analysis was based on the information obtained from site and statistical indicators that were processed to obtain a clear picture of the situation in the examined territory.

Teacher beliefs about teaching science through Science-Technology-Society (STS)

Science.gov (United States)

Massenzio, Lynn

2001-07-01

Statement of the problem. As future citizens, students will have the enormous responsibility of making decisions that will require an understanding of the interaction of science and technology and its interface with society. Since many societal issues today are grounded in science and technology, learning science in its social context is vital to science education reform. Science-Technology-Society (STS) has been strongly identified with meeting this goal, but despite its benefits, putting theory into practice has been difficult. Research design and methodology. The purpose of this study was to explore teacher beliefs about teaching science through STS. The following broad research questions guided the study: (1) What are the participants' initial beliefs about teaching science through STS? (2) What beliefs emerge as participants reflect upon and share their STS instructional experiences with their peers? A social constructivist theoretical framework was developed to plan interactions and collect data. Within this framework, a qualitative methodology was used to interpret the data and answer the research questions. Three provisionally certified science teachers engaged in a series of qualitative tasks including a written essay, verbal STS unit explanation, reflective journal writings, and focus group interviews. After implementing their STS unit, the participants engaged in meaningful dialogue with their peers as they reflected upon, shared, and constructed their beliefs. Conclusions. The participants strongly believed in STS as a means for achieving scientific and technological literacy, developing cognition, enhancing scientific habits of mind and affective qualities, and fostering citizen responsibility. Four major assertions were drawn: (a) Participants' initial belief in teaching for citizen responsibility did not fully align with practice, (b) Educators at the administrative level should be made aware of the benefits of teaching science through STS, (c

Explorations of Tenth-Grade STS[E] Curricula across Three Provincial Political Landscapes

Science.gov (United States)

Phillips, Christina Ann

This thesis focuses on explorations of science, technology, society and the environment (i.e., STS[E]) outcomes/expectations in tenth-grade level science curricula across three Canadian provinces (i.e., Alberta, Manitoba & Ontario) with distinctive provincial political environments at the time of curriculum construction and/or implementation. Document analysis, discourse analysis and a range of theoretical frameworks (i.e., Levinson, 2010; Pedretti & Nazir, 2011 & Krathwohl, 2002) were used to aid in explorations of STS[E] curriculum segments and discourses in each provincial region. More detailed analysis and thematic exploration is presented for each unit associated with climate change as some interesting patterns emerged following initial analysis. My findings are presented as three comparative case studies and represent a small and original contribution to the large body of scholarly research devoted to studies of STS[E] education, where each province represents a unique case that has been explored regarding some aspects the STS[E] curriculum outcomes/expectations and general political culture as well as some other theoretical factors. Findings from this study indicate that Alberta's STS[E] outcomes may be related to Levinson's (2010) 'deliberative' citizenship focus. The following currents from Pedretti and Nazir (2011) appear to be emphasized: logical reasoning, historical, application & design and socio-cultural aligned outcomes when STS[E] is considered as an entity separate from the Alberta curriculum combination of STS and Knowledge. Ontario's STS[E] expectations may align with Levinson's (2010) 'deliberative' or in some select cases a 'deliberative'/'praxis' framework category with some emphasis related to logical reasoning and socio-cultural awareness (Pedretti & Nazir, 2011) in their STS[E] curriculum. The Manitoba STS[E] outcomes may be aligned with a more 'deliberative' approach with some associations that could intersect with the framework

Full Text Available The main objective of this article is the calculation of the Huff Model and the comparison of obtained data with the questionnaire survey results. Afterwards, we will try to assess the validity of this theoretical model of shopping probability for practical use as well as its overall objectivity. Calculation of the Huff Model of Probability will be calculated for nine large-scale retail stores in fifteen local regions within the area of the third largest town in the Slovak Republic - Prešov. These results will be compared to results of the questionnaire research which was conducted during the period of November 2013 until March 2014 on a sample of 1,096 respondents. The questionnaire was addressing customers' preference for various large-scale stores as well as their place of residence. Based on the calculation results and the results obtained from the questionnaire survey, cartographic outputs were created, pointing out overall consistency as well as differences in the already mentioned results.

Simulator testing system (STS)

International Nuclear Information System (INIS)

Miller, V.N.

1990-01-01

In recent years there has been a greater demand placed on the capabilities and time usage of real-time nuclear plant simulators due to NRC, INPO and utilities requirements. The requirements applied to certification, new simulators, upgrades, modifications, and maintenance of the simulators vary; however, they all require the capabilities of the simulator to be tested whether it is for NRC 10CFR55.45b requirements, ATP testing of new simulators, ATP testing of upgrades with or without panels, adding software/hardware due to plant modifications, or analyzing software/hardware problems on the simulator. This paper describes the Simulator Testing System (STS) which addresses each one of these requirements placed on simulators. Special attention will be given to ATP testing of upgrades without the use of control room panels. The capabilities and applications of the four parts of STS which are the Display Control Software (DCS), Procedure Control Software (PCS), Display Generator Software (DGS) and the Procedure Generator Software (PGS) will be reviewed

Nitrile/Buna N Material Failure Assessment for an O-Ring used on the Gaseous Hydrogen Flow Control Valve (FCV) of the Space Shuttle Main Engine

Science.gov (United States)

Wingard, Doug

2006-01-01

After the rollout of Space Shuttle Discovery in April 2005 in preparation for return-to-flight, there was a failure of the Orbiter (OV-103) helium signature leak test in the gaseous hydrogen (GH2) system. Leakage was attributed to the Flow Control Valve (FCV) in Main Engine 3. The FCV determined to be the source of the leak for OV-103 is designated as LV-58. The nitrile/Buna N rubber O-ring seal was removed from LV-58, and failure analysis indicated radial cracks providing leak paths in one quadrant. Cracks were eventually found in 6 of 9 FCV O-rings among the three Shuttle Orbiters, though none were as severe as those for LV-58, OV-103. Testing by EM10 at MSFC on all 9 FCV O- rings included: laser dimensional, Shore A hardness and properties from a dynamic mechanical analyzer (DMA) and an Instron tensile machine. The following test data was obtained on the cracked quadrant of the LV-58, OV-103 O-ring: (1) the estimated compression set was only 9.5%, compared to none for the rest of the O-ring; (2) Shore A hardness for the O.D. was higher by almost 4 durometer points than for the rest of the O-ring; and (3) DMA data showed that the storage/elastic modulus E was almost 25% lower than for the rest of the O-ring. Of the 8 FCV O-rings tested on an Instron, 4 yielded tensile strengths that were below the MIL spec requirement of 1350 psi-a likely influence of rubber cracking. Comparisons were made between values of modulus determined by DNA (elastic) and Instron (Young s). Each nitrile/Buna N O-ring used in the FCV conforms to the MIL-P-25732C specification. A number of such O-rings taken from shelf storage at MSFC and Kennedy Space Center (KSC) were used to generate a reference curve of DMA glass transition temperature (Tg) vs. shelf storage time ranging from 8 to 26 years. A similar reference curve of TGA onset temperature (of rubber weight loss) vs. shelf storage time was also generated. The DMA and TGA data for the used FCV O-rings were compared to the reference

STS-Astro: Astronomy in the focus of Science, Technology and Society and Case Study in Education Distance

Ferreira, O. R.

2014-02-01

The dissertation addresses the focus of Astronomy in Science, Technology and Society [STS}, which the author calls the STS-Astro. Observes the International Year of the Astronomy 2009 [IYA 2009] as one of the greatest experiences STS worldwide, causing unprecedented integration between science, technology and humanities, with positive impacts in many sectors of society and are still worthy of study, specially in Brazil due to the implementation of the International Year of Astronomy, Brazil 2009 [IYABrazil-2009}. Astronomy is also investigated in the area of Education, based mainly on theoretical aspects of educational socio-interacionist of Lev Semenovich Vygotsky (Vygotsky, 1991, 2008 and 2012, p. 103-117) and socio-historical cultural of Paulo Reglus Neves Freire (1979, 1982 and 1996), but when necessary and still keeping the field of constructivism, properly taking advantage of the interactionism and transdisciplinarity of Jean William Fritz Piaget (1983). Concerning Distance Education [DE], it is noted significant growth at the graduate and postgraduate courses. New challenges arise, with the establishment of an increasingly accustomed to Information and Communication Technologies [ICT] and the teaching methodologies to be used and developed, with Astronomy becoming an important instrument in the teaching-learning process associated technologies. Using the methodology of action research, we proceeded with a case study involving 26 students of the discipline of Astronomy Topics applied to Education, between November 1 and December 17, 2012, of the postgraduation courses in Distance Education at the Universidade Cruzeiro do Sul [Southern Cross University]. The results obtained permit statistical surveys therefore quantitative, but also qualitative information about the teaching-learning Astronomy by DE. Analyses of performance and progress of each student and set permit a finding interaction among those involved in the mediation of the teacher-tutor who, in turn

1999-01-01

During the third launch preparations in the Operations and Checkout Building, STS-93 Commander Eileen M. Collins waves while having her launch and entry suit checked. After Space Shuttle Columbia's July 20 and 22 launch attempts were scrubbed, the launch was again rescheduled for Friday, July 23, at 12:24 a.m. EDT. STS-93 is a five-day mission primarily to release the Chandra X-ray Observatory, which will allow scientists from around the world to study some of the most distant, powerful and dynamic objects in the universe. The STS-93 crew numbers five: Commander Collins, Pilot Jeffrey S. Ashby, and Mission Specialists Stephen A. Hawley (Ph.D.), Catherine G. Coleman (Ph.D.) and Michel Tognini of France, with the Centre National d'Etudes Spatiales (CNES). Collins is the first woman to serve as commander of a shuttle mission.

STS-99 workers move new Master Events Controller into aft compartment

Science.gov (United States)

2000-01-01

At Launch Pad 39A, workers move the replacement Enhanced Main Events Controller (E-MEC) into Shuttle Endeavour's aft compartment in the payload bay. The original E-MEC became suspect during the Jan. 31 launch countdown and mission STS-99 was delayed when NASA managers decided to replace it. Each Shuttle carries two enhanced master events controllers (E-MECs), which provide relays for onboard flight computers to send signals to arm and fire pyrotechnics that separate the solid rockets and external tank during assent. Both E-MECs are needed for the Shuttle to be cleared for flight. Currently Endeavour and Columbia are the only two orbiters with the E-MECs. Built by Rockwell's Satellite Space Electronics Division, Anaheim, Calif., each unit weighs 65 pounds and is approximately 20 inches long, 13 inches wide and 8 inches tall. Previously, three Shuttle flights have been scrubbed or delayed due to faulty MECs: STS-73, STS-49 and STS-41-D. The next scheduled date for launch of STS-99 is Feb. 11 at 12:30 p.m. EST.

We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables the detection and reconstruction of neutrinos produced by the interaction of cosmic rays in Earth's atmosphere at energies as low as ˜5 GeV . That energy threshold permits measurements of muon neutrino disappearance, over a range of baselines up to the diameter of the Earth, probing the same range of L /Eν as long-baseline experiments but with substantially higher-energy neutrinos. This analysis uses neutrinos from the full sky with reconstructed energies from 5.6 to 56 GeV. We measure Δ m322=2.31-0.13+0.11×10-3 eV2 and sin2θ23=0.5 1-0.09+0.07, assuming normal neutrino mass ordering. These results are consistent with, and of similar precision to, those from accelerator- and reactor-based experiments.

Reactivación ovárica postparto en bovinos. Revisión.

2001-09-01

Full Text Available Durante las últimas semanas de la gestación, la placenta bovina aumenta la síntesis de estradiol a un nivel que supera centenas de veces la cantidad que produce durante el estro. Ese alto nivel de estradiol produce una retroalimentación negativa prolongada sobre el hipotálamo, que inhibe la síntesis y liberación de hormona liberadora de gonadotropinas (GnRH y por lo tanto en la sangre no circulan las hormonas hipofisiarias que estimulan el crecimiento folicular. Bajo esta condición hormonal, los folículos ováricos se pueden desarrollar hasta formar antro, pero debido a la ausencia de estímulo gonadotrópico, su crecimiento es limitado y no alcanza a formar ondas foliculares. Con la expulsión de la placenta durante el parto, se termina la producción de estradiol y el hipotálamo inicia la recuperación de la capacidad de sintetizar GnRH y de restablecer paulatinamente la sensibilidad a los estrógenos ováricos para restaurar el mecanismo de retroalimentación positivo que controla la liberación de las hormonas folículoestimulante (FSH y luteinizante (LH para estimular el crecimiento y la maduración final del folículo, la síntesis de estradiol, la expresión del estro y la ovulación.

Photonuclear excitation of 103Rh by synchrotron radiation

International Nuclear Information System (INIS)

Yoshihara, Kenji; Kaji, Harumi; Sekine, Tsutomu; Mukoyama, Takeshi

1989-01-01

Photonuclear excitation of the 103 Rh nucleus was studied using synchrotron radiation. Formation of the excited state was confirmed by observing K X-rays emitted following the isomeric transition of the 103m Rh with a low-energy photon spectrometer. The intensity of induced activity due to 103 Rh(γ,γ') 103m Rh reaction was determined carefully by subtracting the fluorescent K X-rays due to natural background radiation. The integral cross-section for isomer production of 103m Rh by resonance absorption of photons at 295 keV is found to be (2.1±0.8) x 10 -28 cm 2 eV and is compared with that estimated from the previous experimental value for the 1277-keV level.

Ferrocene, ruthenocene or rhodocene analogues of Haloperidol. Synthesis and organ distribution after labelling with 103Ru or 103mRh

International Nuclear Information System (INIS)

Wenzel, M.; Wu, Y.

1988-01-01

Ferrocene-Haloperidol was synthesized by N-alkylation of 4-(4'-chlorophenyl)-4-hydroxypiperidine with 1-ferrocenyl-4-chlor-butan-1-on. By heating the ferrocene-haloperidol with 103 RuCl 3 the 103 Ru-labelled ruthenocene-haloperidol was obtained. This compound showed a high affinity for lung but not for brain in rats and mice. The decay of the 103 Ru labelled compound results in the formation of the 103m Rh labelled rhodocene-haloperidol, which is rapidly oxidized by air to the corresponding rhodocinium-haloperidol. This compound can be separated by extraction and TLC. (author)

Airborne particulate matter and spacecraft internal environments

Science.gov (United States)

Liu, Benjamin Y. H.; Rubow, Kenneth L.; Mcmurry, Peter H.; Kotz, Thomas J.; Russo, Dane

1991-01-01

Instrumentation, consisting of a Shuttle Particle Sampler (SPS) and a Shuttle Particle Monitor (SPM), has been developed to characterize the airborne particulate matter in the Space Shuttle cabin during orbital flight. The SPS size selectively collects particles in four size fractions (0-2.5, 2.5-10, 10-100, and greater than 100 microns) which are analyzed postflight for mass concentration and size distribution, elemental composition, and morphology. The SPM provides a continuous record of particle concentration through photometric light scattering. Measurements were performed onboard Columbia, OV-102, during the flight of STS-32 in January 1990. No significant changes were observed in the particle mass concentration, size distribution, or chemical composition in samples collected during flight-day 2 and flight-day 7. The total mass concentration was 56 microg/cu cm with approximately half of the particles larger than 100 microns. Elemental analysis showed that roughly 70 percent of the particles larger than 2.5 microns were carbonaceous with small amounts of other elements present. The SPM showed no temporal or spatial variation in particle mass concentration during the mission.

Expanding Possibilities for Intervention against Small Ruminant Lentiviruses through Genetic Marker-Assisted Selective Breeding

Directory of Open Access Journals (Sweden)

Donald P. Knowles

2013-06-01

Full Text Available Small ruminant lentiviruses include members that infect sheep (ovine lentivirus [OvLV]; also known as ovine progressive pneumonia virus/maedi-visna virus and goats (caprine arthritis encephalitis virus [CAEV]. Breed differences in seroprevalence and proviral concentration of OvLV had suggested a strong genetic component in susceptibility to infection by OvLV in sheep. A genetic marker test for susceptibility to OvLV has been developed recently based on the TMEM154 gene with validation data from over 2,800 sheep representing nine cohorts. While no single genotype has been shown to have complete resistance to OvLV, consistent association in thousands of sheep from multiple breeds and management conditions highlight a new strategy for intervention by selective breeding. This genetic marker-assisted selection (MAS has the potential to be a useful addition to existing viral control measures. Further, the discovery of multiple additional genomic regions associated with susceptibility to or control of OvLV suggests that additional genetic marker tests may be developed to extend the reach of MAS in the future. This review will cover the strengths and limitations of existing data from host genetics as an intervention and outline additional questions for future genetic research in sheep, goats, small ruminant lentiviruses, and their host-pathogen interactions.

Investigation of Space Transportation System (STS) Atmospheric Luminosities (ISAL) experiment documentation includes vertical tail and orbital maneuvering system (OMS) pods with surface glow against the blackness of space. This glowing scene was provided by a long duration exposure with a 35mm camera aimed toward the tail of the Earth-orbiting Challenger, Orbiter Vehicle (OV) 099. OV-099 was maneuvered to a 120-nautical-mile altitude and flown with open payload bay (PLB) in the velocity vector for the conducting of a test titled, 'Evaluation of Oxygen Interaction with Materials (EOIM)'. Atomic oxygen within the low orbital environment is known to be extremely reactive when in contact with solid surfaces. In the darkened area between the camera and the glowing OMS pods and vertical stabilizer are two trays of test materials.

The faulty Master Events Controller is carried away from STS-99 Endeavour

Science.gov (United States)

2000-01-01

Workers carry away the faulty Enhanced Main Events Controller (E- MEC) from Shuttle Endeavour at Launch Pad 39A. The E-MEC became suspect during the Jan. 31 launch countdown and mission STS-99 was delayed when NASA managers decided to replace it. Each Shuttle carries two enhanced master events controllers (E-MECs), which provide relays for onboard flight computers to send signals to arm and fire pyrotechnics that separate the solid rockets and external tank during assent. Both E-MECs are needed for the Shuttle to be cleared for flight. Currently Endeavour and Columbia are the only two orbiters with the E-MECs. Built by Rockwell's Satellite Space Electronics Division, Anaheim, Calif., each unit weighs 65 pounds and is approximately 20 inches long, 13 inches wide and 8 inches tall. Previously, three Shuttle flights have been scrubbed or delayed due to faulty MECs: STS-73, STS-49 and STS-41-D. The next scheduled date for launch of STS-99 is Feb. 11 at 12:30 p.m. EST.

Graphical abstract: - Highlights: • Comparing band gaps values obtained optically with STS. • Comparing direct imaging with calculated dimensions. • STS determination of the interfacial band bending of metal/chalcogenide. - Abstract: The electronic structure at the interface of chalcogenide/metal hybrid nanostructure (CdSe–Au tipped) had been studied by UHV scanning tunneling spectroscopy (STS) technique at room temperature. This nanostructure was synthesized by a phase transfer chemical method. The optical absorption of this hybrid nanostructure was recorded, and the application of the effective mass approximation (EMA) model gave dimensions that were confirmed by the direct measurements using the scanning tunneling microscopy (STM) as well as the high-resolution transmission electron microscope (HRTEM). The energy band gap obtained by STS agrees with the values obtained from the optical absorption. Moreover, the STS at the interface of CdSe–Au tipped hybrid nanostructure between CdSe of size about 4.1 ± 0.19 nm and Au tip of size about 3.5 ± 0.29 nm shows a band bending about 0.18 ± 0.03 eV in CdSe down in the direction of the interface. Such a result gives a direct observation of the electron accumulation at the interface of CdSe–Au tipped hybrid nanostructure, consistent with its energy band diagram. The presence of the electron accumulation at the interface of chalcogenides with metals has an important implication for hybrid nanoelectronic devices and the newly developed plasmon/chalcogenide photovoltaic solar energy conversion.

2018-01-01

To improve science teachers to develop the STS lesson plans for enhancing the students' inventive thinking skills, the workshop of improving science teachers to develop the STS lesson plans for enhancing the Inventive thinking skills were organized. The paper aimed to clarify what teachers learn from the workshop. The goal of the activity of the workshop aimed to: 1) improve participants a better understanding of the relationship between the Inquiry based learning with STS approach, 2) understand the meaning and importance of the STS approach and identify the various stages of Yuenyong (2006) STS learning process, 3) discuss what they learned from the examples of Yuenyong (2006) lesson plan, 4) develop some activities for each stage of Yuenyong (2006) STS approach, and 5) ideas of providing STS approach activities for enhancing inventive thinking skills. Participants included 3 science teachers who work in Khon Kaen, Thailand. Methodology regarded interpretive paradigm. Teachers' learning about pedagogy of enhancing the students' inventive thinking skills will be interpreted through participant observation, teachers' tasks, and interview. The finding revealed that all participants could demonstrate their ideas how to generate the STS lesson plans as a way of enhancing inventive thinking skills. Teachers could mention some element of inventive thinking skills which could be generated on their STS learning activities.

HYTHIRM Radiance Modeling and Image Analyses in Support of STS-119, STS-125 and STS-128 Space Shuttle Hypersonic Re-entries

Gibson, David M.; Spisz, Thomas S.; Taylor, Jeff C.; Zalameda, Joseph N.; Horvath, Thomas J.; Tomek, Deborah M.; Tietjen, Alan B.; Tack, Steve; Bush, Brett C.

2010-01-01

We provide the first geometrically accurate (i.e., 3-D) temperature maps of the entire windward surface of the Space Shuttle during hypersonic reentry. To accomplish this task we began with estimated surface temperatures derived from CFD models at integral high Mach numbers and used them, the Shuttle's surface properties and reasonable estimates of the sensor-to-target geometry to predict the emitted spectral radiance from the surface (in units of W sr-1 m-2 nm-1). These data were converted to sensor counts using properties of the sensor (e.g. aperture, spectral band, and various efficiencies), the expected background, and the atmosphere transmission to inform the optimal settings for the near-infrared and midwave IR cameras on the Cast Glance aircraft. Once these data were collected, calibrated, edited, registered and co-added we formed both 2-D maps of the scene in the above units and 3-D maps of the bottom surface in temperature that could be compared with not only the initial inputs but also thermocouple data from the Shuttle itself. The 3-D temperature mapping process was based on the initial radiance modeling process. Here temperatures were guessed for each node in a well-resolved 3-D framework, a radiance model was produced and compared to the processed imagery, and corrections to the temperature were estimated until the iterative process converged. This process did very well in characterizing the temperature structure of the large asymmetric boundary layer transition the covered much of the starboard bottom surface of STS-119 Discovery. Both internally estimated accuracies and differences with CFD models and thermocouple measurements are at most a few percent. The technique did less well characterizing the temperature structure of the turbulent wedge behind the trip due to limitations in understanding the true sensor resolution.

STS-110 mission specialist Lee M.E. Morin carries an affixed 35 mm camera to record work which is being performed on the International Space Station (ISS). Working with astronaut Jerry L. Ross (out of frame), the duo completed the structural attachment of the S0 (s-zero) truss, mating two large tripod legs of the 13 1/2 ton structure to the station's main laboratory during a 7-hour, 30-minute space walk. The STS-110 mission prepared the Station for future space walks by installing and outfitting the 43-foot-long S0 truss and preparing the Mobile Transporter. The S0 Truss was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first 'space railroad,' which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. Milestones of the S-110 mission included the first time the ISS robotic arm was used to maneuver space walkers around the Station and marked the first time all space walks were based out of the Station's Quest Airlock. It was also the first Shuttle to use three Block II Main Engines. The Space Shuttle Orbiter Atlantis, STS-110 mission, was launched April 8, 2002 and returned to Earth April 19, 2002.

Hydroxyl-dependent Evolution of Oxygen Vacancies Enables the Regeneration of BiOCl photocatalyst

KAUST Repository

Wu, Sujuan

2017-05-02

Photoinduced oxygen vacancies (OVs) are widely investigated as a vital point defect in wide-band-gap semiconductors. Still, the formation mechanism of OVs remains unclear in various materials. To elucidate the formation mechanism of photoinduced OVs in bismuth oxychloride (BiOCl), we synthesized two surface hydroxyl discrete samples in light of the discovery of the significant variance of hydroxyl groups before and after UV light exposure. It is noted that OVs can be obtained easily after UV light irradiation in the sample with surface hydroxyl groups, while variable changes were observed in samples without surface hydroxyls. Density functional theory (DFT) calculations reveal that the binding energy of Bi-O is drastically influenced by surficial hydroxyl groups, which is intensely correlated to the formation of photoinduced OVs. Moreover, DFT calculations reveal that the adsorbed water molecules are energetically favored to dissociate into separate hydroxyl groups at the OV sites via proton transfer to a neighboring bridging oxygen atom, forming two bridging hydroxyl groups per initial oxygen vacancy. This result is consistent with the experimental observation that the disappearance of photoinduced OVs and the recovery of hydroxyl groups on the surface of BiOCl after exposed to a H2O(g)-rich atmosphere, and finally enables the regeneration of BiOCl photocatalyst. Here, we introduce new insights that the evolution of photoinduced OVs is dependent on surface hydroxyl groups, which will lead to the regeneration of active sites in semiconductors. This work is useful for controllable designs of defective semiconductors for applications in photocatalysis and photovoltaics.

Grammatical Conception of Yuriy Shevel'ov: Nominative ↔ Vocative in the System of Substantial Categoriality

Directory of Open Access Journals (Sweden)

Anatoliy Zahnitko

2016-08-01

Full Text Available Background. Analysis of Yuriy Shevel'ov’s approaches to the interpretation of the morphological tier of language, as well as his examination of particular phenomena of this level – substantiality, verbality, and others – reflects not only the author's understanding itself of all the grammatical system as a whole, and morphological one in particular, but also represents the features of modification of scientific approaches in the history of linguistic thought of mid-twentieth century, its strengthening in the studies of the XX – XXI century. The researcher’s definition of nominative and vocative cases as interrelated within the categorical substantiality is of particular importance. Purpose: to determine the main components of interpretation of the status dimension of the nominative and vocative cases within morpho-substantial categoriality of Yuriy Shevel'ov with the definition of theoretical foundations and practical principles, revealing the patterns of establishing internal sentence dimension of the nominative and vocative cases. Results: In the case theory with reliance on the sequence of forms of dependencies in the internal sentence space Yuriy Shevel'ov distinguishes five cases: genitive, dative, accusative, ablative, locative. In the statement about the nominative as grammatically independent case the scientist relies on sentence. Two-dimensionality of grammatically independent case opposes to the one-dimensional grammatically dependent nominative that is traceable in syntactic positions of predicate and apposition. Yuriy Shevel'ov did not consider addressing that is not grammatically linked to the sentence with a specific expression as an individual case. The forms of vocative case show functional three-componentity, because in its functional-semantic paradigm it covers the function of the addressee – potential subject of action (primary function that is represented in formal grammar sentence structure by the main element of

Live footage of a preflight interview with Pilot Scott J. Horowitz is seen. The interview addresses many different questions including why Horowitz became an astronaut, the events that led to his interest, any role models that he had, and his inspiration. Other interesting information that this one-on-one interview discusses is the reaction and reasons for the splitting-up of the objectives for STS-101 with STS-106. Horowitz also mentions the scheduled space-walk, docking with the International Space Station (ISS), the new glass cockpit of Atlantis, the repairs of equipment and change of the batteries. Horowitz also discusses his responsibilities during the space-walk, and docking of the spacecraft. He stresses that he will have an added challenge during the space-walk, his inability to see where he needs to place the Extravehicular Activities (EVA) crew.

Scattering of fast neutrons from 103Rh

International Nuclear Information System (INIS)

Barnard, E.; Reitmann, D.

1978-01-01

The scattering of fast neutrons from 103 Rh was studied by means of (n, n), (n, n') and (n, n'γ) measurements at neutron energies up to 2 MeV. More than fifty unknown γ-transitions were identified and a level scheme established which includes fifteen unreported excited states. Branching ratios, spins and parities for these levels were deduced, as well as the effective activation cross sections for the 103 Rh(n, n')sup(103m)Rh reaction. The results are compared with existing data and with calculations based on the optical and statistical models. (Auth.)

The Sheehan Suicidality Tracking Scale (S-STS) is a patient self-report or clinician-administered rating scale that tracks spontaneous and treatment-emergent suicidal ideation and behaviors. This study set out to evaluate the reliability, convergent and divergent validity of the S-STS in a sample of college students, a population with a high risk of completed and attempted suicide. Cross-sectional, survey design. Participants (303 undergraduate students; males: 42%) completed several measures assessing psychological distress (General Health Questionnaire; GHQ); self-esteem (Rosenberg Self Esteem Scale; RSES); social support (Modified Social Support Survey; MOSSS); and suicidal behavior, including ideation and attempts (S-STS). Both internal consistency and test-retest stability were excellent for the S-STS-global score. The S-STS subscale on suicide ideation also showed good reliability, while the subscale on suicidal behavior showed some inconsistency at retest. Convergent and divergent validity of S-STS was confirmed. All S-STS items loaded on a single factor, which had an excellent fit for the unidimensional model, thus justifying the use of the S-STS as a screening tool. In a mediation model, self-esteem and social support explained 45% of the effects of psychological distress on suicide ideation and behavior as measured by the S-STS-global score. This study provided promising evidence on the convergent, divergent, internal consistency and test-retest stability of the Sheehan Suicidality Tracking Scale. The cross-sectional design and lack of measures of hopelessness and helplessness prevent any conclusion about the links of suicidal behavior with self-esteem and social support.

Ferrocene, ruthenocene or rhodocene analogues of Haloperidol. Synthesis and organ distribution after labelling with /sup 103/Ru or /sup 103m/Rh

Energy Technology Data Exchange (ETDEWEB)

Wenzel, M; Wu, Y

1988-01-01

Ferrocene-Haloperidol was synthesized by N-alkylation of 4-(4'-chlorophenyl)-4-hydroxypiperidine with 1-ferrocenyl-4-chlor-butan-1-on. By heating the ferrocene-haloperidol with /sup 103/RuCl/sub 3/ the /sup 103/Ru-labelled ruthenocene-haloperidol was obtained. This compound showed a high affinity for lung but not for brain in rats and mice. The decay of the /sup 103/Ru labelled compound results in the formation of the /sup 103m/Rh labelled rhodocene-haloperidol, which is rapidly oxidized by air to the corresponding rhodocinium-haloperidol. This compound can be separated by extraction and TLC.

Liu, Kun; Liu, Yong; Yan, Jianchao; Sun, Zhenyuan

2018-03-25

Partial body weight support or loading sit-to-stand (STS) rehabilitation can be useful for persons with lower limb dysfunction to achieve movement again based on the internal residual muscle force and external assistance. To explicate how the muscles contribute to the kinetics and kinematics of STS performance by non-invasive in vitro detection and to nondestructively estimate the muscle contributions to STS training with different loadings, a wearable sensor system was developed with ground reaction force (GRF) platforms, motion capture inertial sensors and electromyography (EMG) sensors. To estimate the internal moments of hip, knee and ankle joints and quantify the contributions of individual muscle and gravity to STS movement, the inverse dynamics analysis on a simplified STS biomechanical model with external loading is proposed. The functional roles of the lower limb individual muscles (rectus femoris (RF), gluteus maximus (GM), vastus lateralis (VL), tibialis anterior (TA) and gastrocnemius (GAST)) during STS motion and the mechanism of the muscles' synergies to perform STS-specific subtasks were analyzed. The muscle contributions to the biomechanical STS subtasks of vertical propulsion, anteroposterior (AP) braking and propulsion for body balance in the sagittal plane were quantified by experimental studies with EMG, kinematic and kinetic data.

Bi-phase CO{sub 2} cooling of the CBM STS detector

Energy Technology Data Exchange (ETDEWEB)

Lavrik, Evgeny [Physikalisches Institut der Universitaet Tuebingen (Germany); Collaboration: CBM-Collaboration

2016-07-01

The Compressed Baryonic Matter (CBM) experiment aims to study the properties of nuclear matter at high net-baryon densities. The Silicon Tracking System (STS) is the key detector to reconstruct charged particle tracks created in heavy-ion interactions. The foreseen interaction rate of up to 10 MHz requires radiation hard detectors as well as efficient cooling of the silicon sensors. To avoid thermal runaway the system must be kept at -5 C or below all the time. This is rather challenging because the overall thermal load in the 2 m{sup 3} STS enclosure is up to 40 kW. Because of these requirements liquid CO{sub 2} is used as a cooling agent as it is superior in terms of volumetric heat transfer coefficient compared to other agents. This contribution shows the thermal simulations and measurement results of the STS front-end electronic boxes as well as an overview of 1 kW TRACI-XL cooling plant developed at GSI and its use to perform thermal measurements of a fully heat loaded STS quarter station.

The sustainability paradigm and the STS approach: mediations for science education

Full Text Available The society has been confronted with issues that involve interactions between science, technology and society (STS, which reveal social, economic, environmental, ethical implications, among others. The sustainability paradigm occupies a prominent position in this area. We understand that the STS guidelines are an important instrument for building the concept of sustainability in science education, whose perspectives consistent with the formation of citizens with environmental sensitivity-citizens who are able to analyze and evaluate critically issues related to the social, environmental and economic field, among other aspects. We propose, in this article, to discuss the possible links between the sustainability paradigm, the STS approach and the process of teaching and learning in science. This articulation certainly helps to think the implications of the current development model and the relationships STS, inserted, for example, on various issues, contexts, dimensions, knowledge and teaching strategies. Certainly, we must undertake the effort to approximate the natural and social fields, in the apprehension of the complex reality as it stands nowadays

Nakai, Takashi; Kouno, Shinji; Hiruma, Naoya; Shuzo, Masaki; Delaunay, Jean-Jacques; Yamada, Ichiro

Polyisobutylene (PIB) polymer and methylphenylsiloxane (25%) diphenylsiloxane (75%) copolymer (OV25) were coated on Quartz Crystal Microbalance (QCM) sensors and used in recognition of bread key odorants. Representative compounds of key roasty odorants of bread were taken as 3-acetylpyridine and benzaldehyde, and representative key fatty odorants were hexanal and (E)-2-nonenal. Both OV25- and PIB-coated QCM fabricated sensors could detect concentration as low as 0.9 ppm of 3-acetylpyridine and 1.2 ppm of (E)-2-nonenal. The sensitivity to 3-acetylpyridine of the OV25-coated QCM was about 1000 times higher than that of ethanol, the major interference compound in bread key odorant analysis. Further, the OV25-coated QCM response was 5-6 times and 2-3 times larger than that of the PIB-coated QCM when exposed to roasty odorants and to fatty odorants, respectively. The difference in sensitivity of the OV25- and PIB-coated QCMs we fabricated made possible to discriminate roasty from fatty odorants as was evidenced by the odor recognition map representing the frequency shifts of the OV25-coated QCM against the frequency shift of the PIB-coated QCM. In conclusion, we found that the combination of an OV25-coated QCM and a PIB-coated QCM was successful in discriminating roasty odorants from fatty odorants at the ppm level.

2016-03-15

To improve the surface hardness of the STS304, Yttria stabilized zirconia (YSZ) films with nano-sized grain were deposited by an aerosol-deposition (AD) method. Coating layers showed dense structure and had -5µm thickness. When 3 mol% YSZ powders with tetragonal phase were deposited on STS304 substrate, tetragonal structure was transformed to cubic structure due to the high impact energy during the AD process. At the same time, strong impact by YSZ particles allowed the austenite phase in STS304 to be transformed into martensite phase. Surface hardness measured with nano indentor showed that YSZ coated film had 11.5 GPa, which is larger value than 7 GPa of STS304.

To evaluate the patterns of regression of iris melanoma after treatment with palladium-103 ( 103 Pd) plaque brachytherapy. Retrospective, nonrandomized, interventional case series. Fifty patients with primary malignant melanoma of the iris. Palladium-103 plaque brachytherapy. Changes in tumor size, pigmentation, and vascularity; incidence of iris neovascularization; and radiation-related complications. The mean age in the case series was 61.2±14.9 years. The mean tumor thickness was 1.4±0.6 mm. According to the American Joint Committee on Cancer, eighth edition, staging criteria for iris melanoma, 21 tumors (42%) were T1a, 5 tumors (10%) were T1b, and 24 tumors (48%) were T2a. The tumor was melanotic in 37 cases (74%) and amelanotic in 13 cases (26%); of these, 13 tumors (26%) showed variable pigmentation. After brachytherapy, mean tumor thickness decreased to 0.9±0.2 mm. Pigmentation increased in 32 tumors (64%), decreased in 11 tumors (22%), and was unchanged in 6 tumors (12%). For intrinsic vascularity (n = 19), 12 tumors (63%) showed decrease and 7 tumors (37%) showed complete resolution. Appearance of ectropion uveae showed diminution in 15 tumors (43%); newly present corectopia was observed in 6 patients (12%). On high-frequency ultrasound imaging, of the 42 tumors (84%) with low to moderate internal reflectivity, 30 tumors (60%) showed an increase in internal reflectivity on regression. Iris stromal atrophy was noted in 26 patients (52%), progression or new-onset cataract was noted in 22 patients (44%), neovascular glaucoma was noted in 1 patient (2%), and there were no cases of corneal opacity. There was no clinical evidence (0%) of radiation-induced retinopathy, maculopathy, or optic neuropathy. Mean follow-up in this series was 5.2 years (range, 0.5-17 years). The most common findings related to iris melanoma regression after 103 Pd plaque brachytherapy included decreased intrinsic tumor vascularity, increased tumor pigmentation, and decreased tumor

Aging is the main risk factor associated with AD. Drug discovery based on nutraceutical molecules for prevention and treatment of AD is a growing topic. In this sense, carotenoids are phytochemicals present mainly in fruits and vegetables with reported benefits for human health. In this research, the anti-amyloidogenic activity of three carotenoids, cryptocapsin, cryptocapsin-5,6-epoxide, and zeaxanthin, was assessed. Cryptocapsin showed the highest bioactivity, while cryptocapsin-5,6-epoxide and zeaxanthin exhibited similar activity on anti-aggregation assays. Molecular modeling analysis revealed that the evaluated carotenoids might follow two mechanisms for inhibiting Aβ aggregation: by preventing the formation of the fibril and through disruption of the Aβ aggregates. Our studies provided evidence that cryptocapsin, cryptocapsin-5,6-epoxide, and zeaxanthin have anti-amyloidogenic potential and could be used for

Discovery of novel antiviral agents is essential because viral infection continues to threaten human life globally. Various heterocyclic small molecules have been developed as antiviral agents. The 5,6-dimethoxyindan-1-on nucleus is of considerable interest as this ring is the key constituent in a range of bioactive compounds, both naturally occurring and synthetic, and often of considerable complexity. The main purpose of this research was to discover and develop small molecule heterocycles as broad-spectrum of antiviral agents. A focused small set of 5,6-dimethoxyindan-1-one analogs (6-8) along with a thiopene derivative (9) was screened for selected viruses (Vaccinia virus - VACA, Human papillomavirus - HPV, Zika virus - ZIKV, Dengue virus - DENV, Measles virus - MV, Poliovirus 3 - PV, Rift Valley fever virus - RVFV, Tacaribe virus - TCRV, Venezuelan equine encephalitis virus - VEEV, Herpes simplex virus 1 -HSV-1 and Human cytomegalovirus - HCMV) using the National Institute of Allergy and Infectious Diseases (NIAID)'s Division of Microbiology and Infectious Diseases (DMID) antiviral screening program. These molecules demonstrated moderate to excellent antiviral activity towards variety of viruses. The 5,6-dimethoxyindan-1-one analog (7) demonstrated high efficacy towards vaccinia virus (EC50: 30.00 µM) in secondary plaque reduction assay. The thiophene analog (9) has shown very good viral inhibition towards several viruses such as Human papillomavirus, Measles virus, Rift Valley fever virus, Tacaribe virus and Herpes simplex virus 1. Our research identified a novel 5,6-dimethoxyindan-1-one analog (compound 7), as a potent antiviral agent for vaccinia virus, and heterocyclic chalcone analog (compound 9) as a broad spectrum antiviral agent.

Lim, U. J.; Yun, B. D.; Kim, J. J.

2006-01-01

Prevention of crevice corrosion was studied for STS 304 stainless steel using a Mg-alloy galvanic anode in solutions with various specific resistivity. The crevice corrosion and corrosion protection characteristics of the steel was investigated by the electrochemical polarization and galvanic corrosion tests. Experimental results show that the crevice corrosion of STS 304 stainless steel does not occur in solutions of high specific resistivity, but it occurs in solutions of low specific resistivity like in solutions with resistivities of 30, 60 and 115 Ω · m. With decreasing specific resistivity of the solution, the electrode potential of STS 304 stainless steel in the crevice is lowered. The potential of STS 304 stainless steel in the crevice after coupling is cathodically polarized more by decreasing specific resistivity indicating that the crevice corrosion of STS 304 stainless steel is prevented by the Mg-alloy galvanic anode

1998-10-01

Self-transcendence has been shown to be related to well-being in older adults, women with breast cancer, women with AIDS, gay men with AIDS, and a healthy population. The purpose of this descriptive pilot study was to examine self-transcendence in another high-priority population: older men with prostate cancer. A convenience sample of 23 men, age 60 and older (M = 69), from three prostate cancer support groups completed Reed's Self-Transcendence Scale (STS) and a demographic data form. The men were predominantly white (82.6%), of the Catholic faith (56.5%), married (78.3%), and not working (87.0%). Over half (65.2%) had a college degree or higher; most viewed their health as good (69.6%) or excellent (21.7%); and the majority (56.5%) viewed their prostate cancer as affecting some of their daily activities. These men scored high on the STS (M = 50.07), which was consistent with previous findings in other populations. Findings of this study contribute to Reed's middle-range theory of self-transcendence. The discovery that self-transcendence is relevant to this group of older men with prostate cancer provides a basis for nurses to investigate the phenomenon in this population and help their clients explore the benefits of the self-transcendence resource.

103Ru for tumor scanning, 2

International Nuclear Information System (INIS)

Mizukawa, Kiichiro

1979-01-01

The mechanism of 103 Ru-uptake in tumors was investigated through the incubation of rat ascites hepatoma cells (AH-130) in vitro with various concentrations of Ru-chloride containing 103 Ru-chloride as a tracer. Quantitative analysis of Ru binding to the cells indicated that ascites hepatoma cells contained high- and low-affinity binding sites for Ru. When ascites hepatoma cells were incubated with Ru after incubation with a low concentration of papain, most of the Ru was not bound to the cells but was found in the medium containing solubilized glycoproteins. However Ru bound mainly to washed cells after the incubation with papain. About 65% of the Ru bound to ascites hepatoma cells was liberated by the papain treatment, and about 45% of the liberated Ru was precipitated by cetyltrimethylammonium bromide, indicating that Ru bound tightly to glycopeptides. These results suggest that the tumor affinity of 103 Ru is related to specific binding to glycopeptides on the tumor cell surface. (author)

Separation of 103Pd from metal Rhodium by dry distillation

International Nuclear Information System (INIS)

Szuecs, Z.; Takacs, S.

2009-01-01

Complete text of publication follows. Introduction. The use of Auger emitters as potential radiopharmaceuticals is increasingly investigated. One such radionuclide of interest is 103m Rh. This can be produced from 103 Ru or from 103 Pd in an in vivo generator. It has been proven on theoretical considerations that use of 103 Pd/ 103m Rh in vivo generator will be successful in delivering 103 mRh to a target site when complexed to a tumor selective carrier. 103 Pd is widely used in internal radiotherapy with one of the production routes via the irradiation of Rh by protons in a cyclotron. The charged particle production of 103 Pd is the only way for no-carrier -added production of this radionuclide, which is required for use in nuclear medicine. However, the widely used separation technique to get 103 Pd from the target material (as well as recovery of the Rh) by wet chemistry is a very complicated, labour intensive and expensive procedure, resulting in low yields of 103 Pd and high amounts of radioactive waste. An alternative more efficient separation and production technology can be developed based on differential evaporation. The principle is the following: The produced 103 Pd 'contaminating' new element within the crystal structure of the Rh target can be forced to diffuse out from the deformed crystal lattice by heating up the target. In this process the 103 Pd accumulates on the surface of the target from where it can be evaporated. A prerequisite for this process is that the target metal (Rh) has a different partial pressure than the evaporated metal (Pd). The thick target yield is 6MBq/μ Ah and the activities of potential contaminating radioisotopes produced by side reaction are negligible, if the energy of the irradiating beam will be chosen precisely. The natural abundance of 116 Cd is 7,5%, it means that the price of the enriched material is reasonable. A potential cyclotron facility with α-beam was found at JINR, Dubna, Russia where the radiochemical

STS-68 Mission Insignia

1994-01-01

This STS-68 patch was designed by artist Sean Collins. Exploration of Earth from space is the focus of the design of the insignia, the second flight of the Space Radar Laboratory (SRL-2). SRL-2 was part of NASA's Mission to Planet Earth (MTPE) project. The world's land masses and oceans dominate the center field, with the Space Shuttle Endeavour circling the globe. The SRL-2 letters span the width and breadth of planet Earth, symbolizing worldwide coverage of the two prime experiments of STS-68: The Shuttle Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) instruments; and the Measurement of Air Pollution from Satellites (MAPS) sensor. The red, blue, and black colors of the insignia represent the three operating wavelengths of SIR-C/X-SAR, and the gold band surrounding the globe symbolizes the atmospheric envelope examined by MAPS. The flags of international partners Germany and Italy are shown opposite Endeavour. The relationship of the Orbiter to Earth highlights the usefulness of human space flights in understanding Earth's environment, and the monitoring of its changing surface and atmosphere. In the words of the crew members, the soaring Orbiter also typifies the excellence of the NASA team in exploring our own world, using the tools which the Space Program developed to explore the other planets in the solar system.

A new Master Events Controller is prepared for installation in STS-99 Endeavour

Science.gov (United States)

2000-01-01

A new Enhanced Main Events Controller (E-MEC) for Shuttle Endeavour sits on a table in a Quality trailer in the Launch Pad 39B area. The original E-MEC in Endeavour became suspect during the Jan. 31 launch countdown and mission STS-99 was delayed when NASA managers decided to replace it. Each Shuttle carries two enhanced master events controllers (E-MECs), which provide relays for onboard flight computers to send signals to arm and fire pyrotechnics that separate the solid rockets and external tank during assent. The E-MECs are located in the orbiter's aft compartment and both are needed for the Shuttle to be cleared for flight. Currently Endeavour and Columbia are the only two orbiters with the E-MECs. Built by Rockwell's Satellite Space Electronics Division, Anaheim, Calif., each unit weighs 65 pounds and is approximately 20 inches long, 13 inches wide and 8 inches tall. Previously, three Shuttle flights have been scrubbed or delayed due to faulty MECs: STS-73, STS-49 and STS-41-D. Before workers can begin E-MEC replacement efforts at the launch pad, cryogenic reactants must be offloaded from the orbiter and Space Shuttle ordnance disconnected. The next scheduled date for launch of STS-99 is Feb. 11 at 12:30 p.m. EST.

STS 304 steel is used as pressure vessel material, and although it exhibits excellent mechanical characteristics at a low temperature, it is heavier than other materials. To address this issue, a method using cold-stretching techniques for STS 304 can be applied. In this study, a cold-stretching part and welded joint specimen were directly obtained from a cold-stretching pressure vessel manufactured according to ASME code. Fatigue crack propagation tests were carried out at room temperature and -170℃ using the compliance method for stress ratios of 0.1 and 0.5. The results indicate that crack growth rate of the welded joint is higher than that of the cold-stretching part within the same stress intensity factor range. The outcome of this work is expected to serve as a basis for the development of a cold-stretched STS 304 pressure vessel.

We present the fundamental stellar and planetary properties of the transiting planetary system WASP-13 within the framework of the Homogeneous Study of Transiting Systems (HoSTS). HoSTS aims to derive the fundamental stellar (T{sub eff}, [Fe/H], M{sub *}, R{sub *}) and planetary (M{sub pl}, R{sub pl}, T{sub eq}) physical properties of known transiting planets using a consistent methodology and homogeneous high-quality data set. Four spectral analysis techniques are independently applied to a Keck+HIRES spectrum of WASP-13 considering two distinct cases: unconstrained parameters and constrained log g from transit light curves. We check the derived stellar temperature against that from a different temperature diagnostic based on an INT+IDS H{alpha} spectrum. The four unconstrained analyses render results that are in good agreement, and provide an improvement of 50% in the precision of T{sub eff}, and of 85% in [Fe/H] with respect to the WASP-13 discovery paper. The planetary parameters are then derived via the Monte Carlo Markov Chain modeling of the radial velocity and light curves, in iteration with stellar evolutionary models to derive realistic uncertainties. WASP-13 (1.187 {+-} 0.065 M{sub Sun }; 1.574 {+-} 0.048 R{sub Sun }) hosts a Saturn-mass, transiting planet (0.500 {+-} 0.037 M{sub Jup}; 1.407 {+-} 0.052 R{sub Jup}), and is at the end of its main-sequence lifetime (4-5.5 Gyr). Our analysis of WASP-13 showcases that both a detailed stellar characterization and transit modeling are necessary to well determine the fundamental properties of planetary systems, which are paramount in identifying and determining empirical relationships between transiting planets and their hosts.

Stratigraphic and tectonic control of deep-water scarp accumulation in Paleogene synorogenic basins: a case study of the Súľov Conglomerates (Middle Váh Valley, Western Carpathians

Directory of Open Access Journals (Sweden)

Soták Ján

2017-10-01

Full Text Available The Súľov Conglomerates represent mass-transport deposits of the Súľov-Domaniža Basin. Their lithosomes are intercalated by claystones of late Thanetian (Zones P3 - P4, early Ypresian (Zones P5 - E2 and late Ypresian to early Lutetian (Zones E5 - E9 age. Claystone interbeds contain rich planktonic and agglutinated microfauna, implying deep-water environments of gravity-flow deposition. The basin was supplied by continental margin deposystems, and filled with submarine landslides, fault-scarp breccias, base-of-slope aprons, debris-flow lobes and distal fans of debrite and turbidite deposits. Synsedimentary tectonics of the Súľov-Domaniža Basin started in the late Thanetian - early Ypresian by normal faulting and disintegration of the orogenic wedge margin. Fault-related fissures were filled by carbonate bedrock breccias and banded crystalline calcite veins (onyxites. The subsidence accelerated during the Ypresian and early Lutetian by gravitational collapse and subcrustal tectonic erosion of the CWC plate. The basin subsided to lower bathyal up to abyssal depth along with downslope accumulation of mass-flow deposits. Tectonic inversion of the basin resulted from the Oligocene - early Miocene transpression (σ1 rotated from NW-SE to NNW-SSE, which changed to a transpressional regime during the Middle Miocene (σ1 rotated from NNE-SSW to NE-SW. Late Miocene tectonics were dominated by an extensional regime with σ3 axis in NNW-SSE orientation.

Adapting the European tourism indicators system to Braşov – tourist destination

Directory of Open Access Journals (Sweden)

Gabriel BRĂTUCU

2015-12-01

Full Text Available The industry of tourism contributes mainly to the social and economic development of a destination. However this development has to be made in a sustainable manner, with an emphasis on preserving the area where it is practiced. In order to evaluate the sustainable development of a destination, the European Commission developed an Indicators System that measures and monitors, at a local level, the processes of sustainable development and communicates to the interested parties its progress and its future performances. Therefore, the aim of this paper is to identify the set of indicators from European Tourism Indicators System that are relevant in evaluating the sustainable development of tourism in Braşov. In order to achieve this objective 3 focus Groups were conducted among 30 specialists in this field. The results can serve as a guid

Full Text Available Voluntary activities have become natural concerns among an increasing number of European citizens. Romania, as a member state of the EU, has a low number of participations in voluntary activities, situation partly justified by the lack of presence of our country on the map of large scale events organization which is based to a high extent, on volunteers’ involvement. The present paper presents the results of a quantitative marketing research organized among volunteers who participated at EYOF 2013 Braşov and highlights the participation’s motivations and benefits felt by volunteers at the end of the event. The authors of the article highlight the differences reported between volunteers’ expectations and their opinions after the event, the results obtained being considered useful for planning the voluntary activities in organizing future events hosted in our country.

Science.gov (United States)

1999-01-01

During final launch preparations in the Operations and Checkout Building, STS-93 Mission Specialist Steven A. Hawley (Ph.D.)gets help donning his launch and entry suit from a suit tech. After Space Shuttle Columbia's July 20 launch attempt was scrubbed at the T-7 second mark in the countdown, the launch was rescheduled for Thursday, July 22, at 12:28 a.m. EDT. The target landing date is July 26, 1999, at 11:24 p.m. EDT. STS-93 is a five-day mission primarily to release the Chandra X-ray Observatory, which will allow scientists from around the world to study some of the most distant, powerful and dynamic objects in the universe. The new telescope is 20 to 50 times more sensitive than any previous X- ray telescope and is expected unlock the secrets of supernovae, quasars and black holes. The STS-93 crew numbers five: Commander Eileen M. Collins, Pilot Jeffrey S. Ashby, and Mission Specialists Hawley, Catherine G. Coleman (Ph.D.) and Michel Tognini of France, with the Centre National d'Etudes Spatiales (CNES). Collins is the first woman to serve as commander of a shuttle mission.

The crew assigned to the STS-61B mission included Bryan D. O'Conner, pilot; Brewster H. Shaw, commander; Charles D. Walker, payload specialist; mission specialists Jerry L. Ross, Mary L. Cleave, and Sherwood C. Spring; and Rodolpho Neri Vela, payload specialist. Launched aboard the Space Shuttle Atlantis November 28, 1985 at 7:29:00 pm (EST), the STS-61B mission's primary payload included three communications satellites: MORELOS-B (Mexico); AUSSAT-2 (Australia); and SATCOM KU-2 (RCA Americom). Two experiments were conducted to test assembling erectable structures in space: EASE (Experimental Assembly of Structures in Extravehicular Activity), and ACCESS (Assembly Concept for Construction of Erectable Space Structure). In a joint venture between NASA/Langley Research Center in Hampton, VA and the Marshall Space Flight Center (MSFC), ACCESS and EASE were developed and demonstrated at MSFC's Neutral Buoyancy Simulator (NBS). In this STS-61B onboard photo, astronaut Ross was working on the ACCESS experiment during an Extravehicular Activity (EVA). The primary objective of this experiment was to test the ACCESS structural assembly concept for suitability as the framework for larger space structures and to identify ways to improve the productivity of space construction.

The functional organization of the left STS: a large scale meta-analysis of PET and fMRI studies of healthy adults

Science.gov (United States)

Liebenthal, Einat; Desai, Rutvik H.; Humphries, Colin; Sabri, Merav; Desai, Anjali

2014-01-01

The superior temporal sulcus (STS) in the left hemisphere is functionally diverse, with sub-areas implicated in both linguistic and non-linguistic functions. However, the number and boundaries of distinct functional regions remain to be determined. Here, we present new evidence, from meta-analysis of a large number of positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) studies, of different functional specificity in the left STS supporting a division of its middle to terminal extent into at least three functional areas. The middle portion of the left STS stem (fmSTS) is highly specialized for speech perception and the processing of language material. The posterior portion of the left STS stem (fpSTS) is highly versatile and involved in multiple functions supporting semantic memory and associative thinking. The fpSTS responds to both language and non-language stimuli but the sensitivity to non-language material is greater. The horizontal portion of the left STS stem and terminal ascending branches (ftSTS) display intermediate functional specificity, with the anterior-dorsal ascending branch (fatSTS) supporting executive functions and motor planning and showing greater sensitivity to language material, and the horizontal stem and posterior-ventral ascending branch (fptSTS) supporting primarily semantic processing and displaying greater sensitivity to non-language material. We suggest that the high functional specificity of the left fmSTS for speech is an important means by which the human brain achieves exquisite affinity and efficiency for native speech perception. In contrast, the extreme multi-functionality of the left fpSTS reflects the role of this area as a cortical hub for semantic processing and the extraction of meaning from multiple sources of information. Finally, in the left ftSTS, further functional differentiation between the dorsal and ventral aspect is warranted. PMID:25309312

Importancia del Factor de Crecimiento del Endotelio Vascular (VEGF y de sus receptores en el ciclo ovárico. Revisión

Directory of Open Access Journals (Sweden)

Ana María Rosales Torres

2012-01-01

Full Text Available El objetivo de esta revisión fue recopilar y analizar la información más reciente acerca del papel del Factor de Crecimiento del Endotelio Vascular (VEGF, por sus siglas en inglés, sus receptores de membrana (VEGFR1 y VEGFR2 y receptores solubles (sVEGFR1 y sVEGFR2, durante los procesos involucrados en el ciclo ovárico. La principal función del sistema VEGF (VEGF y sus receptores, es controlar la formación de nuevos vasos sanguíneos y la protección de células endoteliales y de la granulosa. Es conocido que durante el ciclo ovárico, los cambios vasculares son importantes para controlar el desarrollo folicular, la ovulación y la formación y regresión del cuerpo lúteo (CL. En la selección folicular, VEGF y el receptor VEGFR2 incrementan su expresión para favorecer el aporte de nutrientes al folículo. En la ovulación VEGF, VEGFR1 y VEGFR2m reducen su expresión para evitar una hemorragia, y se incrementa inmediatamente después para promover la formación de vasos sanguíneos y el desarrollo del CL. Finalmente durante la regresión del CL el VEGF y VEGFR2 reducen su expresión coincidiendo con la muerte de las células que lo forman. Las evidencias revisadas permiten sugerir que VEGF y VEGFR2 son los principales promotores de la angiogénesis y protección celular en el desarrollo del folículo y CL, sin embargo los otros miembros del sistema VEGF; VEGFR1 y sVEGFR1 y sVEGFR2, parecen desempeñar funciones anti-angiogénicas en los procesos ováricos mencionados.

The objectives of the present work are to increase thermal stability of cyclotron targets for production of Tl-201 isotope, increase Tl-203 regeneration rate at radiochemical reprocessing of the targets and develop production technology for radiochemical sources based on Rd-103 isotope. Electrochemical coating of copper substrate with Tl increased the beam current at target irradiation from 100 μA to 125 μA. Further increase of the beam current results in sharp decrease of target stability time at irradiation to 15 min at beam current 150 μA. Thermal calculations and tests at the electron-beam stand predict satisfactory stability at such currents. The discrepancy with the irradiation results has not been explained. More accurate specification of regimes for Tl-203 electrochemical recovery from irradiated targets and better matching of the electrolyte composition made it possible to increase the recovery rate up to 99.5%. Before the present Project, the INP had no experience in production of radioactive sources based on Pd-103. Thermo-diffusion extraction of Pd-103 from irradiated rhodium foil has been chosen as a technology-defining method. The process assures good extraction rate and high purity of extracted isotope. Production of Pd-103 sources based on this technology is much simpler compared to the same based on electrochemical processes. (author)

Virtual reconstruction of the Australopithecus africanus pelvis Sts 65 with implications for obstetrics and locomotion.

Science.gov (United States)

Claxton, Alexander G; Hammond, Ashley S; Romano, Julia; Oleinik, Ekaterina; DeSilva, Jeremy M

2016-10-01

Characterizing australopith pelvic morphology has been difficult in part because of limited fossilized pelvic material. Here, we reassess the morphology of an under-studied adult right ilium and pubis (Sts 65) from Member 4 of Sterkfontein, South Africa, and provide a hypothetical digital reconstruction of its overall pelvic morphology. The small size of the pelvis, presence of a preauricular sulcus, and shape of the sciatic notch allow us to agree with past interpretations that Sts 65 likely belonged to a female. The morphology of the iliac pillar, while not as substantial as in Homo, is more robust than in A.L. 288-1 and Sts 14. We created a reconstruction of the pelvis by digitally articulating the Sts 65 right ilium and a mirrored copy of the left ilium with the Sts 14 sacrum in Autodesk Maya. Points along the arcuate line were used to orient the ilia to the sacrum. This reconstruction of the Sts 65 pelvis looks much like a "classic" australopith pelvis, with laterally flared ilia and an inferiorly deflected pubis. An analysis of the obstetric dimensions from our reconstruction shows similarity to other australopiths, a likely transverse or oblique entrance of the neonatal cranium into the pelvic inlet, and a cephalopelvic ratio similar to that found in humans today.

2012-11-01

Full Text Available Abstract Background Technological leaps in genome sequencing have resulted in a surge in discovery of human disease genes. These discoveries have led to increased clarity on the molecular pathology of disease and have also demonstrated considerable overlap in the genetic roots of human diseases. In light of this large genetic overlap, we tested whether cross-disease research approaches lead to faster, more impactful discoveries. Methods We leveraged several gene-disease association databases to calculate a Mutual Citation Score (MCS for 10,853 pairs of genetically related diseases to measure the frequency of cross-citation between research fields. To assess the importance of cooperative research, we computed an Individual Disease Cooperation Score (ICS and the average publication rate for each disease. Results For all disease pairs with one gene in common, we found that the degree of genetic overlap was a poor predictor of cooperation (r2=0.3198 and that the vast majority of disease pairs (89.56% never cited previous discoveries of the same gene in a different disease, irrespective of the level of genetic similarity between the diseases. A fraction (0.25% of the pairs demonstrated cross-citation in greater than 5% of their published genetic discoveries and 0.037% cross-referenced discoveries more than 10% of the time. We found strong positive correlations between ICS and publication rate (r2=0.7931, and an even stronger correlation between the publication rate and the number of cross-referenced diseases (r2=0.8585. These results suggested that cross-disease research may have the potential to yield novel discoveries at a faster pace than singular disease research. Conclusions Our findings suggest that the frequency of cross-disease study is low despite the high level of genetic similarity among many human diseases, and that collaborative methods may accelerate and increase the impact of new genetic discoveries. Until we have a better

The discovery of the periodic table as a case of simultaneous discovery.

Science.gov (United States)

Scerri, Eric

2015-03-13

The article examines the question of priority and simultaneous discovery in the context of the discovery of the periodic system. It is argued that rather than being anomalous, simultaneous discovery is the rule. Moreover, I argue that the discovery of the periodic system by at least six authors in over a period of 7 years represents one of the best examples of a multiple discovery. This notion is supported by a new view of the evolutionary development of science through a mechanism that is dubbed Sci-Gaia by analogy with Lovelock's Gaia hypothesis. © 2015 The Author(s) Published by the Royal Society.

STS-84 oxygen generator for Mir installation

Science.gov (United States)

1997-01-01

In the SPACEHAB Payload Processing Facility, McDonnell Douglas- SPACEHAB technicians prepare a Russian-made oxygen generator for flight in a SPACEHAB Double Module. The oxygen generator, manufactured in Russia by RSC Energia, will be carried aboard the Space Shuttle Atlantis on Mission STS-84 for the Shuttles scheduled docking with the Russian Space Station Mir next month. The nearly 300-pound generator will replace one of two Mir units that have been malfunctioning recently. The generator functions by electrolysis, which separates water into its oxygen and hydrogen components. The hydrogen is vented and the oxygen is used for breathing by the Mir crew. The generator is 4.2 feet in length and 1.4 feet in diameter. STS-84, which is planned to include a Mir crew exchange of astronaut C. Michael Foale for Jerry M. Linenger, is targeted for a May 15 liftoff. It will be the sixth Shuttle-Mir docking.

Han, Hyemin; Jeong, Changwoo

2014-03-01

This study develops a Science-Technology-Society (STS)-based science ethics education program for high school students majoring in or planning to major in science and engineering. Our education program includes the fields of philosophy, history, sociology and ethics of science and technology, and other STS-related theories. We expected our STS-based science ethics education program to promote students' epistemological beliefs and moral judgment development. These psychological constructs are needed to properly solve complicated moral and social dilemmas in the fields of science and engineering. We applied this program to a group of Korean high school science students gifted in science and engineering. To measure the effects of this program, we used an essay-based qualitative measurement. The results indicate that there was significant development in both epistemological beliefs and moral judgment. In closing, we briefly discuss the need to develop epistemological beliefs and moral judgment using an STS-based science ethics education program.

Tank 241-B-103 tank characterization plan

International Nuclear Information System (INIS)

Carpenter, B.C.

1995-01-01

The Defense Nuclear Facilities Safety Board (DNFSB) has advised the US Department of Energy (DOE) to concentrate the near-term sampling and analysis activities on identification and resolution of safety issues. The data quality objective (DQO) process was chosen as a tool to be used to identify sampling and analytical needs for the resolution of safety issues. As a result, a revision in the Federal Facility Agreement and Consent Order (Tri-Party Agreement or TPA) milestone M-44-00 has been made, which states that ''A Tank Characterization Plan (TCP) will also be developed for each double-shell tank (DST) and single-shell tank (SST) using the DQO process... Development of TCPs by the DQO process is intended to allow users (e.g., Hanford Facility user groups, regulators) to ensure their needs will be met and that resources are devoted to gaining only necessary information.'' This document satisfies that requirement for Tank 241-B-103 (B-103) sampling activities. Tank B-103 was placed on the Organic Watch List in January 1991 due to review of TRAC data that predicts a TOC content of 3.3 dry weight percent. The tank was classified as an assumed leaker of approximately 30,280 liters (8,000 gallons) in 1978 and declared inactive. Tank B-103 is passively ventilated with interim stabilization and intrusion prevention measures completed in 1985

Tank 24-C-103 headspace flammability

International Nuclear Information System (INIS)

Huckaby, J.L.

1994-05-01

Information regarding flammable vapors, gases, and aerosols is presented and interpreted to help resolve the tank 241-C-103 headspace flammability issue. Analyses of recent vapor and liquid samples, as well as visual inspections of the tank headspace, are discussed in the context of tank dynamics. Concern that the headspace of tank 241-C-103 may contain a flammable mixture of organic vapors and an aerosol of combustible organic liquid droplets arises from the presence of a layer of organic liquid in the tank. This organic liquid is believed to have originated in the plutonium-uranium extraction (PUREX) process, having been stored initially in tank 241-C-102 and apparently transferred to tank 241-C-103 in 1975 (Carothers 1988). Analyses of samples of the organic liquid collected in 1991 and 1993 indicate that the primary constituents are tributyl phosphate (TBP) and several semivolatile hydrocarbons (Prentice 1991, Pool and Bean 1994). This is consistent with the premise that the organic waste came from the PUREX process, because the PUREX process used a solution of TBP in a diluent composed of the n-C 11 H 24 to n-C 15 H 32 normal paraffinic hydrocarbons (NPH)

The association between lower preoperative hematocrit (Hct) and risk for morbidity/mortality after cardiac surgery is well established. We examined whether the impact of low preoperative Hct on outcome is modified by blood transfusion and operative risk in women and men undergoing nonemergent CABG surgery. Patients having nonemergent, first-time, isolated CABG were included (N=2757). Logistic regressions assessed effect of hematocrit on major perioperative morbidity/mortality separately by males (n=2232) and females (n=525). Mean age was 63.2±10.1years, preoperative hematocrit was 38.9±4.8%, and STS risk score was 1.3±1.8%. Blood transfusion was more likely in female patients (26% vs. 12%, Ptransfusion in males and females, whereas older age (OR=1.03, P=0.017) also predicted transfusion in females. Major morbidity was also more likely in female patients (12% vs. 7%, Pblood transfusion was the only predictive factor for major morbidity in females (OR=4.56, Pblood transfusion (OR=9.22, Pblood transfusion and major morbidities after nonemergent CABG. Traditional factors that have been found to predict outcomes, such as hematocrit and STS risk, were related only to major morbidity in male patients. However, blood transfusion negatively impacted major outcome after nonemergent CABG surgery across all STS risk levels in both genders. Copyright © 2015 Elsevier Inc. All rights reserved.

1989-01-01

The STS-29 Space Shuttle Discovery mission approaches for a landing at NASA's then Ames-Dryden Flight Research Facility, Edwards AFB, California, early Saturday morning, 18 March 1989. Touchdown was at 6:35:49 a.m. PST and wheel stop was at 6:36:40 a.m. on runway 22. Controllers chose the concrete runway for the landing in order to make tests of braking and nosewheel steering. The STS-29 mission was very successful, completing the launch a Tracking and Data Relay communications satellite, as well as a range of scientific experiments. Discovery's five man crew was led by Commander Michael L. Coats, and included pilot John E. Blaha and mission specialists James P. Bagian, Robert C. Springer, and James F. Buchli. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their orbital missions, they streak back through the atmosphere and land like airplanes. The returning shuttles, however, land like gliders, without power and on runways. Other rockets can place heavy payloads into orbit, but, they can only be used once. Space Shuttles are designed to be continually reused. When Space Shuttles are used to transport complete scientific laboratories into space, the laboratories remain inside the payload

The 103 Rh(n,n ' ) 103 Rh m cross section was measured by the activation method in the neutron energy range 5.7 endash 12 MeV with an uncertainty of ≅5%. Monoenergetic neutrons produced by the D(d,n) 3 He reaction were used to irradiate metallic Rh samples at 0 degree relative to the deuteron beam. The K x rays from 103 Rh m were measured with a calibrated Si detector, and the neutron fluence was determined by means of a 238 U fission chamber. The measured cross sections resolve the discrepancies in previous data and agree with the results of recent statistical model calculations of the fast-neutron cross sections of rhodium. copyright 1996 The American Physical Society

2013-01-01

Several distinct definitions of postoperative death have been used in various quality reporting programs. Some have defined a postoperative mortality as a patient who expires while still in the hospital, while others have considered all deaths occurring within a predetermined, standardized time interval after surgery. While if continues to collect mortality data using both these individual definitions, the Society of Thoracic Surgeons (STS) believes that either alone may be inadequate. Accordingly, the STS prefers a more encompassing metric, Operative Mortality, which is defined as (1) all deaths occurring during the hospitalization in which the operation was performed, even if after 30 days; and (2) all deaths occurring after discharge from the hospital, but before the end of the thirtieth postoperative day. This manuscript provides clarification for some uncommon but important scenarios where the correct application of this definition may be problematic. PMID:23799748

Reinvestigation of 56Ni decay

International Nuclear Information System (INIS)

Sur, B.; Norman, E.B.; Lesko, K.T.; Browne, E.; Larimer, R.

1990-01-01

In a series of experiments, we have reinvestigated the decay of the doubly magic nucleus 56 Ni, which is believed to be copiously produced in supernovae. We have confirmed its previously known decay scheme and half-life, and have searched for several rare decay modes. We establish an upper limit of 5.8x10 -7 for the branching ratio of the second forbidden unique β + decay to the 158-keV level in 56 Co, leading to a lower limit of 2.9x10 4 yr for the half-life of fully ionized 56 Ni nuclei in cosmic rays. We also establish an upper limit of 5.0x10 -3 for the branching ratio of the isospin forbidden Fermi electron capture transition to the 1451-keV level in 56 Co, which in turn leads to an upper limit of 124 keV for the isospin mixing Coulomb matrix element of the 56 Ni ground state

In vitro evidence indicates that CD56(bright cells are precursors of CD56(dim cells, but in vivo evidence is lacking. Here, we studied NK cells from a patient that suffered from a melanoma and opportunistic fungal infection during childhood. The patient exhibited a stable phenotype characterized by a reduction in the frequency of peripheral blood CD3(-CD56(dim NK cells, accompanied by an overt increase in the frequency and absolute number of CD3(-CD56(bright cells. These NK cells exhibited similar expression of perforin, CD57 and CD158, the major activating receptors CD16, NKp46, NKG2D, DNAM-1, and 2B4, as well as the inhibitory receptor CD94/NKG2A, on both CD56(bright and CD56(dim NK cells as healthy controls. Also, both NK cell subpopulations produced IFN-γ upon stimulation with cytokines, and CD3(-CD56(dim NK cells degranulated in response to cytokines or K562 cells. However, upon stimulation with cytokines, a substantial fraction of CD56(dim cells failed to up-regulate CD57 and CD158, showed a reduction in the percentage of CD16(+ cells, and CD56(bright cells did not down-regulate CD62L, suggesting that CD56(dim cells could not acquire a terminally differentiated phenotype and that CD56(bright cells exhibit a maturation defect that might result in a potential altered migration pattern. These observations, support the notion that NK cells of this patient display a maturation/activation defect that precludes the generation of mature NK cells at a normal rate accompanied by CD56(dim NK cells that cannot completely acquire a terminally differentiated phenotype. Thus, our results provide evidence that support the concept that in vivo CD56(bright NK cells differentiate into CD56(dim NK cells, and contribute to further understand human NK cell ontogeny.

As INSPIRE progresses to be implemented in the EU, many new discovery portals are built to facilitate finding spatial data. Currently the structure of the discovery portals is determined by the way spatial data experts like to work. However, we argue that the main target group for discovery portals are not spatial data experts but professionals with limited spatial knowledge, and a focus outside the spatial domain. An exploratory usability experiment was carried out in which three discovery p...
