    Dual sensor is one of the most promising sensors for humanitarian demining operations. Conventional landmine detection depends on highly trained and focused human operators manually sweeping 1m2 plots with a metal detector and listening for characteristic audio signals indicating the presence of AP (Anti-personnel) landmines. In order to reduce the time of plodding detected objects, metal detectors need to be combined with a complimentary subsurface imaging sensor. i.e., GPR(Ground Penetrating Radar). The demining application requires real-time imaging results with centimetre resolution in a highly portable package. We are currently testing a dual sensor ALIS which is a real-time sensor tracking system based on a CCD camera and image processing. In this paper we introduce ALIS systems which we have developed for detection of buried antipersonnel mines and small size explosives. The performance of ALIS has been tested in Cambodia since 2009. More than 80 anti-personnel mines have been detected and removed from local agricultural area. ALIS has cleared more than 70,000 m2 area and returned it to local farmers.

    The Ngari (Ali) prefecture of Tibet, one of the highest areas in the world, has recently emerged as a promising site for future astronomical observation. Here we use 31 years of reanalysis data from the Climate Forecast System Reanalysis (CFSR) to examine the astroclimatology of Ngari, using the recently-erected Ali Observatory at Shiquanhe (5~047~m above mean sea level) as the representative site. We find the percentage of photometric night, median atmospheric seeing and median precipitable water vapor (PWV) of the Shiquanhe site to be $57\\%$, $0.8"$ and 2.5~mm, comparable some of the world's best astronomical observatories. Additional calculation supports the Shiquanhe region as one of the better sites for astronomical observations over the Tibetan Plateau. Based on the studies taken at comparable environment at Atacama, extraordinary observing condition may be possible at the few vehicle-accessible 6~000~m heights in the Shiquanhe region. Such possibility should be thoroughly investigated in future.

    Full Text Available El presente estudio analiza la existencia pública de Saddam Hussein como un producto del discurso mediático. La prensa estadounidense fue cómplice de la representación mediática que construyó el gobierno de Estados Unidos sobre Saddam Hussein. En este sentido, cuando Saddam Hussein fue útil a sus intereses, fue subvencionado y sus crímenes ignorados. Pero cuando se convirtió en un estorbo se demonizó y finalmente se ejecutó. De manera que la prensa estadounidense excluyó de su discurso la asociación de Estados Unidos con los crímenes perpetrados por Saddam Hussein. Palabras-clave: Discurso periodístico; discurso político; Saddam Hussein; representación. ABSTRACT The present study analyzes the public existence of Saddam Hussein as a product of the media discourse. The American press was agreed with the media representation that built the U. S. government about Saddam Hussein. In this sense, when Saddam Hussein was useful to its interests he was subsidized and his crimes ignored. But when it was a hindrance was demonized and finally was executed. So that the American press excluded of his discourse the association of U.S. with the crimes perpetrated by Saddam Hussein.

    Full Text Available Bu kaçıncı denemem bilmiyorum, ama yazamıyorum bir türlü... Nasıl yazacağımı bilemiyorum ama yazmam gerekiyor. Çünkü O’nu tanıma şansına sahip olduğum için kendimi borçlu hissediyorum. O’nu bilmeyenlere anlatmam gerekiyor. Hani derler ya iyi insanların ardından “Bir yıldız daha kaydı bu dünyadan” diye. Ali Abi yalnızca “iyi” değildi aynı zamanda “asil” idi. Hayata karşı bakışı ve kendisini bekleyen ölümü çok iyi bildiği halde ölüme karşı mağrur ve metanetli duruşu ile gerçekten bize zarafeti gösterdi. John Mc Creery’nin sözü hislerimi anlatıyor: “Ölüm yoktur! Yıldızlar başka bir kıyıda doğmak için batarlar.” Evet Ali Yemişcigil artık başka bir boyutta, dün gece bir yıldız daha kaydı bu dünyadan ve başka bir yerde belki de “görünmezler dünyasında” parlayacak yeniden... Ve kalanlar; metanetli ailesi, üzerine titrediği ailesi, başta sevgili eşi Lale Abla, kızı Serra, oğlu Sefa, annesi, kardeşleri, yakınları, bizler... Onu yakından tanıyanlar olarak gerçekten çok acı çekiyoruz şu anda ama bir yandan da onun yaşama bakışını ve güzelliğini gördüğümüz için de şanslıyız aslında. I Iayat yolculuğunda kaç kişinin yolu böyle bir “Ali insan” ile kesişebilir, kaçımız böyle bir bilgeye rastlayabiliriz? Adının anlamını taşıyordu kişiliğiyle; “yüce” idi. İki gün sonra doğum günü, kırk beş yaşını bitirecekti, sürpriz doğum günü planlarken, sıkça verdiği mesajı bir daha hatırlatarak son dersi verdi Ali Abi; “Carpe diem-Anı yaşa, geleceği planlama, çünkü düşündüğün gibi olmayabilir” derdi hep. Haklısın Abi olmuyormuş, bir kere daha haklısın, maalesef... O’nu genç yaşta kaybettiğimiz için üzgünüz ama her anını dolu dolu yaşamaya çalıştığı hayatıyla kimilerinin 80 yıla sığdıramadıklarını yapabildi ve bu yönüyle örnek oldu. Martin Luther King

    Full Text Available Background and Aim. Mice with alymphoplasia (aly/aly mutation characterized by a lack of lymph nodes, Peyer's patches, and well-defined lymphoid follicles in the spleen were found. In this study, we used splenectomized aly/aly mice to elucidate the effects of secondary lymphoid organs in the development of aly/aly autoimmune pancreatitis. Methods. Forty-eight 10-week-old aly/aly mice were divided into two groups for splenectomy and sham operation. Histological and immunohistochemical analyses of the pancreas were performed at the ages of 20, 30, and 40 weeks old after operation, respectively. Results. Our results showed that mononuclear cell infiltration was restricted to the interlobular connective tissues at the age of 20 weeks, and not increase obviously at the age of 30 and 40 weeks in splenectomized aly/aly mice. Furthermore, an apparent decrease in the expressions of CD4+ T, CD8+ T, and B cells was detected in the pancreatic tissues compared with sham aly/aly mice, however, no significant difference in macrophage expression between mice with and without a splenectomy. Conclusions. Inflammation infiltration and development of the pancreatitis in aly/aly mice were suppressed effectively after splenectomy, which was, at least partly, correlated to inhibition of the infiltration of T and B cells in pancreatic tissues but not to macrophages.

    Full Text Available We are very inaccurate lie detectors, and tend to believe what others tell us is the truth more often than we ought to. In fact, studies on lie detection typically describe our tendency to believe others as an error in judgment. Although people may look like hopeless lie detectors, the Adaptive Lie Detector theory (ALIED claims that people are actually making smart, informed judgments. This article explores the ALIED theory and what it means for those wanting to spot a liar.

    Full Text Available Abstract Background The aim of this report is to address treatment outcomes of patients with early-stage seminoma in a single institution with special reference to patients with history of surgical violation of the scrotum. Methods Seventy four patients with pure seminoma were treated at King Hussein Cancer Center (Amman, Jordan between 2003 and 2010. All patients underwent orchiectomy. All but 3 patients received adjuvant radiotherapy. Patients who underwent surgical violation of the scrotum prior to referral were managed by further excision or irradiation of the scrotal scar. The follow-up ranged from 1 to 200 months (mean, 33 months. Results At the time of follow-up; all but one patient remain alive. The 3-year relapse-free survival for the entire cohort was 95.9%. Three patients developed relapse, all of whom received adjuvant irradiation following inguinal orchiectomy and initially harbored tumors larger than 4 cm upon pathological examination. Median time to relapse was 14 months (range, 8–25 months. None were associated with elevated tumor markers prior to detection of relapse. All but one patient were successfully salvaged by chemotherapy. Conclusions Our results confirm the excellent prognosis of patients with early-stage seminoma treated by orchiectomy and adjuvant radiotherapy in a developing country. Although all patients who developed relapse demonstrated adverse pathological findings upon initial assessment, no consistent predictor of relapse was found. Scrotal scar re-excision or irradiation in patients with prior history of surgical violation of the scrotum are effective measures in preventing local failure.

    Atomic layer deposition (ALD) was used to grow TixAlyN and TixAlyC thin films using trimethylaluminum (TMA), titanium tetrachloride and ammonia as precursors. Deposition temperature was varied between 325 °C and 500 °C. Films were also annealed in vacuum and N2-atmosphere at 600-1000 °C. Wide range of characterization methods was used including time-of-flight elastic recoil detection analysis (ToF-ERDA), X-ray diffractometry (XRD), X-ray reflectometry (XRR), Raman spectroscopy, ellipsometry, helium ion microscopy (HIM), atomic force microscopy (AFM) and 4-point probe measurement for resistivity. Deposited films were roughly 100 nm thick and contained mainly desired elements. Carbon, chlorine and hydrogen were found to be the main impurities.

  9. HfxAlyO ternary dielectrics for InGaAs based metal-oxide-semiconductor capacitors

    Science.gov (United States)

    Krylov, Igor; Ritter, Dan; Eizenberg, Moshe

    2017-07-01

    The electrical properties of HfxAlyO compound dielectric films and the HfxAlyO/InGaAs interface are reported for various dielectric film compositions. Despite the same trimethylaluminum (TMA) pre-deposition treatment, dispersion in accumulation and capacitance-voltage (C-V) hysteresis increased with hafnium content. Different kinds of border traps were identified as being responsible for the phenomena. After anneal, the density of states in the HfxAlyO/InGaAs interface varied quite weakly with dielectric film composition. The optimal composition for obtaining high inversion charge density in metal oxide semiconductor gate stacks is determined by a tradeoff between leakage and dielectric constant, with the optimum atomic cation ratio ([Hf]/[Al]) of ˜1.

  10. Public and private beliefs of political leaders: Saddam Hussein in front of a crowd and behind closed doors

    Directory of Open Access Journals (Sweden)

    Stephen Benedict Dyson

    2014-05-01

    Full Text Available We ask if the public speech of political leaders is diagnostic of their private beliefs, and investigate through content analysis of the rhetoric of Saddam Hussein, the former president of Iraq. We collected Saddam’s public speeches and interviews on international affairs from 1977–2000, producing a data set of 330,000 words. From transcripts of Saddam speaking in private, we garnered a comparison corpus of 58,000 words. These text-sets were processed to locate markers of conflict, control and complexity. We find that Saddam’s hostile, conflict-oriented worldview and his perception of himself as a significant political actor was consistent across public and private domains. The major difference between these spheres was his more complex private view of international affairs compared to his more definitive public stance. Our evidence supports the notion that private beliefs can be inferred from the public speech of political leaders.

ALIS is only one hand-held dual sensor, which can record the sensor position with sensor signals. Therefore, the data can be processed after data acquisition, and can increase the imaging capability. ALIS has been tested in some mine affected courtiers including Afghanistan (2004), Egypt(2005), Croatia(2006-) and Cambodia(2007-). Mine fields at each country has different conditions and soil types. Therefore testes at the real mine fields are very important. ALIS has detected more than 30 AP-Mines in evaluation test in Cambodia held in 2009.

    A comparative study of different sequences of two metal precursors [trimethylaluminum (TMA) and Tris(isopropylcyclopentadienyl) lanthanum (La(iPrCp)3)] for atomic layer deposition (ALD) lanthanum aluminum oxide (LaxAlyO) films is carried out. The percentage compositions of C and N impurity of LaxAlyO films were investigated using in situ X-ray photoelectron spectroscopy (XPS). The effects of different oxidants on the physical and chemical properties and electrical characteristics of LaxAlyO films are studied before and after annealing. Preliminary testing results indicate that the impurity level of LaxAlyO films grown with different oxidants can be well controlled before and after annealing. Analysis indicates the rapid thermal annealing (RTA) and kinds of oxidants have significant effects on the equivalent oxide thickness (EOT), dielectric constant, electrical properties, and stability of LaxAlyO films. Additionally, the change of chemical bond types of rapid thermal annealing effects on the properties of LaxAlyO films are grown with different oxidants also investigated by XPS.

    The Ali observatory, Tibet, is a promising new site identified through ten year site survey over west China, and it is of significance to establish rules of site protection during site development. The site protection program is described with five aspects: site monitoring, technical support, local government support, specific organization, and public education. The long-term sky brightness monitoring is ready with site testing instruments and basic for light pollution measurement; the monitoring also includes directions of main light sources, providing periodical reports and suggestions for coordinating meetings. The technical supports with institutes and manufacturers help to publish lighting standards and replace light fixtures; the research pays special attention to the blue-rich sources, which impact the important application of high altitude sites. An official leading group towards development and protection of astronomical resources has been established by Ali government; one of its tasks is to issue regulations against light pollution, including special restrictions of airport, mine, and winter heating, and to supervise lighting inspection and rectification. A site protection office under the official group and local astronomical society are organized by Ali observatory; the office can coordinate in government levels and promote related activities. A specific website operated by the protection office releases activity propaganda, evaluation results, and technical comparison with other observatories. Both the site protection office and Ali observatory take responsibility for public education, including popular science lectures, light pollution and energy conservation education. Ali Night Sky Park has been constructed and opens in 2014, and provides a popular place and observational experience. The establishment of Ali Observatory and Night Sky Park brings unexpected social influence, and the starry sky trip to Ali becomes a new format of culture

    Universiti Tun Hussein Onn Malaysia (UTHM) is the 15th of the 20 public universities established in Malaysia. UTHM consists of eight faculties. One of them is the Faculty of Mechanical and Manufacturing Engineering (FKMP). The programme offered - Bachelor of Mechanical Engineering with Honours (BDD), undergoes continuous auditing and accreditation by the Engineering Accreditation Council (EAC). To fulfill the requirement for accreditation, EAC requires the faculty to assess and evaluate the programme learning outcomes’ (PLOs) attainment of the graduates, such that all graduates are targeted to achieve the performance indicator (PI) upon graduation. This paper discusses the methods developed by the FKMP for PLOs’ measurement and evaluation. Two approaches are utilized in this regards, (i) the direct assessment based on students’ performance in courses, and (ii) the indirect assessment based the industrial and graduates’ perception. The PLOs’ attainment for graduates of cohort 2010-2012 are analysed in this study. Consolidation data shows that the PI for majority of the PLOs are achieved, indicating that the programme offered complies with the standard expected by different stakeholders.

    Web Services are an XML based technology that allow applications to communicate with each other across disparate systems. Web Services are becoming the de facto standard that enable inter operability between heterogeneous processes and systems. AliEn2 is a grid environment based on web services. The AliEn2 services can be divided in three categories: Central services, deployed once per organization; Site services, deployed on each of the participating centers; Job Agents running on the worker nodes automatically. A security model to protect these services is essential for the whole system. Current implementations of web server, such as Apache, are not suitable to be used within the grid environment. Apache with the mod_ssl and OpenSSL only supports the X.509 certificates. But in the grid environment, the common credential is the proxy certificate for the purpose of providing restricted proxy and delegation. An Authentication framework was taken for AliEn2 web services to add the ability to accept X.509 certificates and proxy certificates from client-side to Apache Web Server. The authentication framework could also allow the generation of access control policies to limit access to the AliEn2 web services.

    Full Text Available Objectives: The aims of the study were to evaluate the role of magnetic resonance arthrography (MRA of the wrist in detecting full-thickness tears of the triangular fibrocartilage complex (TFCC and to compare the results of the magnetic resonance arthrography (MRA with the gold standard arthroscopic findings. Methods:The study was performed at King Hussein Medical Center, Amman, Jordan, between January 2008 and December 2011. A total of 42 patients (35 males and 7 females who had ulnar-sided wrist pain and clinical suspicions of TFCC tears were included in the study. All patients underwent wrist magnetic resonance arthrography (MRA and then a wrist arthroscopy. The results of MRA were compared with the arthroscopic findings. Results: After comparison with the arthroscopic findings, the MRA had three false-negative results (sensitivity = 93% and no false-positive results. A total of 39 patients were able to return to work. Satisfaction was high in 38 of the patients and 33 had satisfactorypain relief. The sensitivity of the wrist MRA in detecting TFCC full-thickness tears was 93% (39, and specificity was 80% (16/20. The overall accuracy of wrist arthroscopy in detecting a full-thickness tear of the TFCC in our study was 85% (29/34. Conclusion: These results illustrate the role of wrist MRA in assessing the TFCC pathology and suggest its use as the first imaging technique, following a plain X-ray, in evaluating patients with chronic ulnar side wrist pain with suspected TFCC injuries.

    Malaria is a serious disease, caused by the parasite of the genus Plasmodium, which was responsible for 440,000 deaths in 2015. Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is one of the main clinical complications in severe malaria. The murine model DBA/2 reproduces the clinical signs of ALI/ARDS in humans, when infected with Plasmodium berghei ANKA. High levels of HO-1 were reported in cases of severe malaria. Our data indicated that the HO-1 mRNA and protein expression are increased in mice that develop malaria-associated ALI/ARDS (MA-ALI/ARDS). Additionally, the hemin, a HO-1 inducing drug, prevented mice from developing MA-ALI/ARDS when administered prior to the development of MA-ALI/ARDS in this model. Also, hemin treatment showed an amelioration of respiratory parameters in mice, high VEGF levels in the sera, and a decrease in vascular permeability in the lung, which are signs of ALI/ARDS. Therefore, the induction of HO-1 before the development of MA-ALI/ARDS could be protective. However, the increased expression of HO-1 on the onset of MA-ALI/ARDS development may represent an effort to revert the phenotype of this syndrome by the host. We therefore confirm that HO-1 inducing drugs could be used for prevention of MA-ALI/ARDS in humans. PMID:27974865

  15. Depletion of REF/Aly alters gene expression and reduces RNA polymerase II occupancy.

    Stubbs, Sarah H; Conrad, Nicholas K

    2015-01-01

    Pre-mRNA processing is mechanistically linked to transcription with RNA pol II serving as a platform to recruit RNA processing factors to nascent transcripts. The TREX complex member, REF/Aly, has been suggested to play roles in transcription and nuclear RNA stability in addition to its more broadly characterized role in mRNA export. We employed RNA-seq to identify a subset of transcripts with decreased expression in both nuclear and cytoplasmic fractions upon REF/Aly knockdown, which implies that REF/Aly affects their expression upstream of its role in mRNA export. Transcription inhibition experiments and metabolic labeling assays argue that REF/Aly does not affect stability of selected candidate transcripts. Instead, ChIP assays and nuclear run-on analysis reveal that REF/Aly depletion diminishes the transcription of these candidate genes. Furthermore, we determined that REF/Aly binds directly to candidate transcripts, supporting a direct effect of REF/Aly on candidate gene transcription. Taken together, our data suggest that the importance of REF/Aly is not limited to RNA export, but that REF/Aly is also critical for gene expression at the level of transcription. Our data are consistent with the model that REF/Aly is involved in linking splicing with transcription efficiency.

    Malaria-associated acute lung injury/acute respiratory distress syndrome (ALI/ARDS) often results in morbidity and mortality. Murine models to study malaria-associated ALI/ARDS have been described; we still lack a method of distinguishing which mice will develop ALI/ARDS before death. This work aimed to characterize malaria-associated ALI/ARDS in a murine model and to demonstrate the first method to predict whether mice are suffering from ALI/ARDS before death. DBA/2 mice infected with Plasmodium berghei ANKA developing ALI/ARDS or hyperparasitemia (HP) were compared using histopathology, PaO2 measurement, pulmonary X-ray, breathing capacity, lung permeability, and serum vascular endothelial growth factor (VEGF) levels according to either the day of death or the suggested predictive criteria. We proposed a model to predict malaria-associated ALI/ARDS using breathing patterns (enhanced pause and frequency respiration) and parasitemia as predictive criteria from mice whose cause of death was known to retrospectively diagnose the sacrificed mice as likely to die of ALI/ARDS as early as 7 days after infection. Using this method, we showed increased VEGF levels and increased lung permeability in mice predicted to die of ALI/ARDS. This proposed method for accurately identifying mice suffering from ALI/ARDS before death will enable the use of this model to study the pathogenesis of this disease.

    Atmospheric optical turbulence modeling and forecast for astronomy is a relatively recent discipline, but has played important roles in site survey, optimization of large telescope observing tables, and in the applications of adaptive optics technique. The numerical approach, by using of meteorological parameters and parameterization of optical turbulence, can provide all the optical turbulence parameters related, such as C2n profile, coherent length, wavefront coherent time, seeing, isoplanatic angle, and so on. This is particularly interesting for searching new sites without the long and expensive site testing campaigns with instruments. Earlier site survey results by the site survey team of National Astronomical Observatories of China imply that the south-west Tibet, Ali, is one of the world best IR and sub-mm site. For searching the best site in Ali area, numerical approach by Weather and Research Forecasting (WRF) model had been used to evaluate the climatology of the optical turbulence. The WRF model is configured over a domain 200km×200km with 1km horizontal resolution and 65 vertical levels from ground to the model top(10millibars) in 2010. The initial and boundary conditions for the model are provided by the 1° × 1° Global Final Analysis data from NCEP. The distribution and seasonal variation of optical turbulence parameters over this area are presented.

The structures highlighted using the filtering techniques suggest that the Miocene aquifer of OAT basin is cut by four major fault systems that trend E-W, NE-SW, NW-SE and NNE-SSW. In addition, a NW-SE gravity model established shows the geometry of the Miocene sandstone reservoir and the Upper Cretaceous limestone rocks. Moreover, the superimposition of the electrical conductivity and the structural maps indicates that the low conductivity values of sampled water from boreholes are located around main faults.

    Full Text Available Abstract Background Following the demise of Jordan's King Hussein bin Talal to cancer in 1999, the country's Al-Amal Center was transformed from a poorly perceived and ineffectual cancer care institution into a Western-style comprehensive cancer center. Renamed King Hussein Cancer Center (KHCC, it achieved improved levels of quality, expanded cancer care services and achieved Joint Commission International accreditation under new leadership over a three-year period (2002–2005. Methods An exploratory case research method was used to explain the rapid change to international standards. Sources including personal interviews, document review and on-site observations were combined to conduct a robust examination of KHCC's rapid changes. Results The changes which occurred at the KHCC during its formation and leading up to its Joint Commission International (JCI accreditation can be understood within the conceptual frame of the transformational leadership model. Interviewees and other sources for the case study suggest the use of inspirational motivation, idealized influence, individualized consideration and intellectual stimulation, four factors in the transformational leadership model, had significant impact upon the attitudes and motivation of staff within KHCC. Changes in the institution were achieved through increased motivation and positive attitudes toward the use of JCI continuous improvement processes as well as increased professional training. The case study suggests the role of culture and political sensitivity needs re-definition and expansion within the transformational leadership model to adequately explain leadership in the context of globalizing health care services, specifically when governments are involved in the change initiative. Conclusion The KHCC case underscores the utility of the transformational leadership model in an international health care context. To understand leadership in globalizing health care services, KHCC

    Catheter-directed thrombolysis (CDT) has been used as the first therapeutic option for acute limb ischemia (ALI) due to its less invasive nature; however, recent systematic review showed higher incidence of major complications related to lytic infusion, including hemorrhagic stroke. In this setting, aspiration thrombectomy with Indigo has the greatest advantage of not increasing systemic risk of bleeding. The Indigo™ system from Penumbra® (Alameda, CA, USA) promotes active thrombectomy using a vacuum pump that generates substantial suction, enabling aspiration of clots of varying sizes and lengths. The device has three components: aspiration catheter, separator and pump. There are 2 aspiration catheter sizes: CAT 3 and CAT 5. The separators are intended to mobilize the clot and clean the catheter lumen, and therefore restoring flow for continuous aspiration. The pump is small-sized equipment capable of applying near pure vacuum aspiration pressure of -29 mmHg. Aspiration thrombectomy with Indigo has two key advantages: it does not require the use of lytics, and it provides immediate flow reestablishment. Its use when thrombolysis is contraindicated or has failed is already well established and, in the future, it may likely become the first line endovascular option in patients with acute limb ischemia.

    TREX is a conserved multiprotein complex that is necessary for efficient mRNA export to the cytoplasm. In Saccharomyces cerevisiae, the TREX complex is additionally implicated in RNA quality control pathways, but it is unclear whether this function is conserved in mammalian cells. The Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 protein binds and recruits the TREX component REF/Aly to viral mRNAs. Here, we demonstrate that REF/Aly is recruited to the KSHV noncoding polyadenylated nuclear (PAN) RNA by ORF57. This recruitment correlates with ORF57-mediated stabilization of PAN RNA, suggesting that REF/Aly promotes nuclear RNA stability. Further supporting this idea, tethering REF/Aly to PAN RNA is sufficient to increase the nuclear abundance and half-life of PAN RNA but is not sufficient to promote its export. Interestingly, REF/Aly appears to protect the poly(A) tail from deadenylation, and REF/Aly-stabilized transcripts are further adenylated over time, consistent with previous reports linking poly(A) tail length with nuclear RNA surveillance. These studies show that REF/Aly can stabilize nuclear RNAs independently of their export and support a broader conservation of RNA quality control mechanisms from yeast to humans.

    Full Text Available According to the teachings of the Shia, Imam Ali (AS has unique features by which he earned the merits of becoming the successor to the Prophet (pbuh as the Imam and Wali. One of the most important of his features is his similarity to the Jesus as one of the greatest prophets before Prophet Muhammad (pbuh. This similarity was first mentioned in some Islamic traditions, especially the ones narrated through Shiite Isnad in interpretation of the verses 57-59 of the Surta Az-Zukhruf. In these traditions, the Prophet has regarded the Position of Imam Ali (AS in his nation the same as Jesus's Position among the Israel. The Quran has cited the inimical arguments of the Arab infidels against this prophet's saying: they considered the worshiping of their own gods better than accepting Prophet's remark in equating his cousin with Jesus (pbuh. By resorting to this remark, the infidels regarded worshiping their own gods more preferable than deifying a man. Therefore, the first and most prominent similarity between Imam Ali (AS and Jesus Christ (pbuh is attributing divinity to Imam Ali (AS, at least by some of his extreme lovers. The Quranic command saying: "Do not Exaggerate about your religion… .(Quran 4:17 refers to the Christian extremism in deifying Jesus, But soon word Ghali was borrowed from this verse and used to refer to Shiite extremists. Moreover, the Quran (4: 159, talks about the advent of Jesus Christ to his followers before their death .The same concept has been mentioned in Shiite traditions about Imam Ali (AS, according to which, he is believed to be present beside every dying Muslim individual. This appearance of Imam Ali (AS would remind us the idea of Imam Ali's (AS return to this world. Thus, the return of Imam Ali (AS to this world is the third similarity between Imam Ali (AS and Jesus Christ (PBUH. Not only the return of Jesus has been mentioned in in the Christian tradition as the one manifested to the apostles after his ascension

  12. Hyperspectral Transformation from EO-1 ALI Imagery Using Pseudo-Hyperspectral Image Synthesis Algorithm

    Tien Hoang, Nguyen; Koike, Katsuaki

    2016-06-01

    Hyperspectral remote sensing is more effective than multispectral remote sensing in many application fields because of having hundreds of observation bands with high spectral resolution. However, hyperspectral remote sensing resources are limited both in temporal and spatial coverage. Therefore, simulation of hyperspectral imagery from multispectral imagery with a small number of bands must be one of innovative topics. Based on this background, we have recently developed a method, Pseudo-Hyperspectral Image Synthesis Algorithm (PHISA), to transform Landsat imagery into hyperspectral imagery using the correlation of reflectance at the corresponding bands between Landsat and EO-1 Hyperion data. This study extends PHISA to simulate pseudo-hyperspectral imagery from EO-1 ALI imagery. The pseudo-hyperspectral imagery has the same number of bands as that of high-quality Hyperion bands and the same swath width as ALI scene. The hyperspectral reflectance data simulated from the ALI data show stronger correlation with the original Hyperion data than the one simulated from Landsat data. This high correlation originates from the concurrent observation by the ALI and Hyperion sensors that are on-board the same satellite. The accuracy of simulation results are verified by a statistical analysis and a surface mineral mapping. With a combination of the advantages of both ALI and Hyperion image types, the pseudo-hyperspectral imagery is proved to be useful for detailed identification of minerals for the areas outside the Hyperion coverage.

    Bronchial epithelium plays a key role in orchestrating innate and adaptive immunity. The fate of ex vivo airway epithelial cultures growing at the air liquid interface (ALI) derived from human endobronchial biopsies or brushings is not easy to predict. Calibrating and differentiating these cells is a long and expensive process requiring rigorous expertise. Pinpointing factors associated with ALI culture success would help researchers gain further insight into epithelial progenitor behavior. A successful ALI culture was defined as one in which a pseudostratified epithelium has formed after 28 days in the presence of all differentiated epithelial cell types. A 4-year prospective bi-center study was conducted with adult subjects enrolled in different approved research protocols. 463 consecutive endobronchial biopsies were obtained from normal healthy volunteers, healthy smokers, asthmatic patients and smokers with COPD. All demographic variables, the different fiber optic centers and culture operators, numbers of endo-bronchial biopsies and the presence of ciliated cells were carefully recorded. Univariate and multivariate models were developed. A stepwise procedure was used to select the final logistic regression model. ALI culture success was independently associated with the presence of living ciliated cells within the initial biopsy (OR = 2.18 [1.50-3.16], p money. It is still unknown whether successful ALI culture is related to indicators of general cell viability or a purported stem cell state specifically associated with ciliated beating cells.

    Eurycoma longifolia, locally known as Tongkat Ali, is a famous medicinal plant in the family of Simaroubaceae and well known for its aphrodisiac properties from its water extract. The root of E. longifolia is used to extract wide range bioactive components of Tongkat Ali. Previous works standardised Tongkat Ali extracts by measuring the concentration of eurycomanone, a quassinoid marker chemical, within the overall extract. There is a newer Malaysian standard that specifies that Tongkat Ali can be standardised to glycosaponin, thus it is desired to determine how extraction parameters such as particle size, extraction temperature, and solvent type affects the glycosaponin content in the extract. The overall study is aimed to determine how the extraction parameters affect the glycosaponin amount in extract. This paper presents the preliminary work where in this study the effect of particle size on overall extract and glycosaponin quantification method development is presented. A reflux extraction method was used to extract Tongkat Ali with a particle size of 0.5 mm, 1.0 mm and 2.0 mm of raw material to study effect of particle size on overall extract. Water and methanol were the two types of solvent used for extraction to study the quantity of glycosaponin.

    The Auroral Large Imaging System (ALIS) was first proposed at the ESA-PAC meeting in Lahnstein 1989. The first spectroscopic imaging station was operational in 1994, and since then up to six stations have been in simultaneous operation. Each station has a scientific-grade CCD-detector and a filter-wheel for narrow-band interference-filters with six positions. The field-of-view is around 70°. Each imager is mounted in a positioning system, enabling imaging of a common volume from several sites. This enables triangulation and tomography. Raw data from ALIS is freely available at ("http://alis.irf.se") and ALIS is open for scientific colaboration. ALIS made the first unambiguous observations of Radio-induced optical emissions at high latitudes, and the detection of water in a Leonid meteor-trail. Both rockets and satellite coordination are considered for future observations with ALIS.

    We compare the electrical properties of HfO2/Al2O3 nano-laminates with those of the ternary HfxAlyO compound in metal oxide semiconductor (MOS) capacitors. The dielectrics were deposited by atomic layer deposition on InGaAs. Water, ozone, and oxygen plasma were tested as oxygen precursors, and best results were obtained using water. The total dielectric thickness was kept constant in our experiments. It was found that the effective dielectric constant increased and the leakage current decreased with the number of periods. Best results were obtained for the ternary compound. The effect of the sublayer thicknesses on the electrical properties of the interface was carefully investigated, as well as the role of post-metallization annealing. Possible explanations for the observed trends are provided. We conclude that the ternary HfxAlyO compound is more favorable than the nano-laminates approach for InGaAs based MOS transistor applications.

    Vinod R M T Balasubramaniam

    Full Text Available We constructed a novel chicken (Gallus gallus lung cDNA library fused inside yeast acting domain vector (pGADT7. Using yeast two-hybrid screening with highly pathogenic avian influenza (HPAI nucleoprotein (NP from the strain (A/chicken/Malaysia/5858/2004(H5N1 as bait, and the Gallus gallus lung cDNA library as prey, a novel interaction between the Gallus gallus cellular RNA export adaptor protein Aly/REF and the viral NP was identified. This interaction was confirmed and validated with mammalian two hybrid studies and co-immunoprecipitation assay. Cellular localization studies using confocal microscopy showed that NP and Aly/REF co-localize primarily in the nucleus. Further investigations by mammalian two hybrid studies into the binding of NP of other subtypes of influenza virus such as the swine A/New Jersey/1976/H1N1 and pandemic A/Malaysia/854/2009(H1N1 to human Aly/REF, also showed that the NP of these viruses interacts with human Aly/REF. Our findings are also supported by docking studies which showed tight and favorable binding between H5N1 NP and human Aly/REF, using crystal structures from Protein Data Bank. siRNA knockdown of Aly/REF had little effect on the export of HPAI NP and other viral RNA as it showed no significant reduction in virus titer. However, UAP56, another component of the TREX complex, which recruits Aly/REF to mRNA was found to interact even better with H5N1 NP through molecular docking studies. Both these proteins also co-localizes in the nucleus at early infection similar to Aly/REF. Intriguingly, knockdown of UAP56 in A549 infected cells shows significant reduction in viral titer (close to 10 fold reduction. Conclusively, our study have opened new avenues for research of other cellular RNA export adaptors crucial in aiding viral RNA export such as the SRSF3, 9G8 and ASF/SF2 that may play role in influenza virus RNA nucleocytoplasmic transport.

    We are in the process of developing a high-resolution landmine scanning system "ALIS" which produces horizontal slices of the shallow subsurface for visualization of buried explosives and inert clutter. As many AP mines contain minimum amounts of metal, metal detectors need to be combined with a complimentary subsurface imaging sensor. Ground Penetrating Radar (GPR) is widely accepted for subsurface sensing in the fields of geology, archaeology and utility detection. The demining application requires real-time imaging results with centimetre resolution in a highly portable package. The key requirement for sharp images of the subsurface is the precise tracking of the geophysical sensor(s) during data collection. We should also notice that GPR system is a very wide band radar system, and equivalent to UWB radar, which has recently been developed for short-range high-accuracy radar. We are testing simplified but effective signal processing for imaging mines. We are currently testing a dual sensor ALIS which is a realtime sensor tracking system based on a CCD camera and image processing. In this paper we introduce the GPR systems which we have developed for detection of buried antipersonnel mines and small size explosives. ALIS has been deployed in Cambodia since 2009 and detected more than 70 mines in mine fields, and returned more than 13ha cleaned fields to local farmers. We also report the current status of ALIS in Cambodia.

    2014-01-01

    This paper provides a review of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Advanced Land Imager (ALI), and Hyperion data and applications of the data as a tool for ore minerals exploration, lithological and structural mapping. Spectral information extraction from ASTER, ALI, and Hyperion data has great ability to assist geologists in all disciplines to map the distribution and detect the rock units exposed at the earth's surface. The near coincidence of Earth Observing System (EOS)/Terra and Earth Observing One (EO-1) platforms allows acquiring ASTER, ALI, and Hyperion imagery of the same ground areas, resulting accurate information for geological mapping applications especially in the reconnaissance stages of hydrothermal copper and gold exploration, chromite, magnetite, massive sulfide and uranium ore deposits, mineral components of soils and structural interpretation at both regional and district scales. Shortwave length infrared and thermal infrared bands of ASTER have sufficient spectral resolution to map fundamental absorptions of hydroxyl mineral groups and silica and carbonate minerals for regional mapping purposes. Ferric-iron bearing minerals can be discriminated using six unique wavelength bands of ALI spanning the visible and near infrared. Hyperion visible and near infrared bands (0.4 to 1.0 μm) and shortwave infrared bands (0.9 to 2.5 μm) allowed to produce image maps of iron oxide minerals, hydroxyl-bearing minerals, sulfates and carbonates in association with hydrothermal alteration assemblages, respectively. The techniques and achievements reviewed in the present paper can further introduce the efficacy of ASTER, ALI, and Hyperion data for future mineral and lithological mapping and exploration of the porphyry copper, epithermal gold, chromite, magnetite, massive sulfide and uranium ore deposits especially in arid and semi-arid territory.

    2015-06-18

    In the local Malaysian context, herbal plants such as Eurycoma longifolia (Tongkat Ali), Orthosiphon stamineus (MisaiKucing), Ficus deltoidea (Mas Cotek), Zingiber officinale (Halia Bara) and Barringtonia racemosa (Putat) are known and widely used for its therapeutic properties. The first part of this study aims to screen for the anti-protozoal activity of these herbal plant extracts against Blastocystis sp. isolate subtype (ST) 3. Herbal extract with the highest efficacy was further fractionized into water and ethyl acetate fractions and tested against ST1, ST3 and ST5 Blastocystis sp. isolates. These isolates were also exposed to allopathic drugs, Metronidazole (MTZ), Tinidazole, Trimethoprim-sulfamethoxazole(TMP-SMX), Ketoconazole and Nitazoxanide for comparison purpose. Blastocystis sp. isolates from human-derived stool samples were exposed to herbal extracts and allopathic drugs at a concentration of 0.1 mg/ml and 1.0 mg/ml and were incubated at 37 °C. Growth profile studies were carried out. After 72 h of treatment, the viability of Blastocystis sp. as a result of the effects of the drugs and herbal extracts were assessed. Based on the screening process, amongst all the extracts, Tongkat Ali exhibited the highest anti-protozoal activity at 1.0 mg/ml. Between the water and ethyl acetate fractions of Tongkat Ali, the ethyl acetate fraction exhibited a slightly higher percentage of anti-protozoal activity at 1.0 mg/ml across subtypes, ST1 (94.9%), ST3 (95.1%) and ST5 (94.3%). When tested with allopathic drugs, at the same concentration, MTZ exhibited the highest anti-protozoal activity across subtypes, ST1 (95.8%), ST3 (93.4%) and ST5 (90.8%). This study is the first to describe the anti-protozoal properties of Tongkat Ali against Blastocystis sp. isolates. Ethyl acetate fraction of Tongkat Ali demonstrated the highest anti-protozoal activity against Blastocystis sp. isolates and showed a sizeable reduction in the cell count which was comparable with MTZ

    2012-12-01

    Full Text Available In Indonesia where the majority of the population is Muslims, pesantren that has thrived since the arrival of Islam to the shore of the archipelago is still out of the central field of the national educational system. As such, pesantren was and is forced to continually be aware with ongoing new educational developments in the country as the result of modernisation and globalisation. The foundation of Ma’had Aly is one of the ways taken by the pesantrens to response to the current developments within Muslim communities, to define or even maintain their central roles as well as to preserve their tradition in such a modernised and globalised Indonesia. By exploring the foundation of Ma’had Alys in Kuningan as a case study, this article closely elaborates how the pesantren world engages these processes both in their cirricular settings and practices and provides how it negotiates with the ongoing changes within its surrounding communities.

    2011-01-01

    To reach its large computing needs, the ALICE experiment at CERN has developed its own middleware called AliEn, centralised and relying on pilot jobs. One of its strength is the automatic installation of the required packages. The Nordic countries have offered a distributed Tier-1 centre for the CERN experiments, where the job management should be done with the NorduGrid middleware ARC. We have developed an interoperation module to allow to unify several computing sites using ARC, and make them look like a single site from the point of view of AliEn. A prototype has been completed and tested out of production. This talk will present implementation details of the system and its performance in tests.

    Since the ALICE experiment began data taking in early 2010, the amount of end user jobs on the AliEn Grid has increased signif icantly. Presently 1/3 of the 40K CPU cores available to ALICE are occupied by jobs submitted by about 400 distinct users, individually or in organized analysis trains. The overall stability of the AliEn middleware has been excellent throughout the 3 years of running, but the massive amount of end-user analysis and its specific requirements and load has revealed few components which can be improved. One of them is the interface between users and central AliEn services (catalogue, job submission system) which we are currently re-implementing in Java . The interface provides persistent connection with enhanced data and job submission authenticity. In this paper we will describe the architecture of the new interface, the ROOT binding which enables the use of a single interface in addition to the standard UN IX-like access shell and the new security-related features.

    Full Text Available The study area is a part of Cenozoic magmatic belt of Central Iran, which is located in the West of Yazd porovince. Contact metamorphism and skarn occurred in conglomerate part of Sngestan Formation. The Oligocene intrusion bodies of Ali-Abad-Darreh Zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setting. The main mineral assemblage of skarn in order of imprtance is as follow: Garnet + epidote + quartz + calcite + pyrite + iron oxides. Brown garnets are the skarn characteristic mineral. EPMA analysis has shown that the chemical composition with garnet belong to andradite-grossular solid-solution (And 65, Gross 30 with more andradite component. The high permeability and presence of carbonate pebbles in conglomerate are two important factors for fluid flow and genesis of garnets. Distinct oscillatory zoning in garnets is resulted from the change of fO2 in fluids. The evolution of Ali-Abad skarn is took place in the range of 380 to 530 ºC, 0.5 Kbar pressure and high fO2. Also close association of this skarn with Ali-Abad intrusive with Cu-porphyry mineralization shows that this skarn is a Cu-porphyry type skarn.

    The AliEn Grid Services, as operated by the ALICE Collaboration in its global physics analysis grid framework, is based on a central File Catalogue together with a distributed set of storage systems and the possibility to register links to external data resources. This paper describes several identified vulnerabilities in the AliEn File Catalogue access protocol regarding fraud and unauthorized file alteration and presents a more secure and revised design: a new mechanism, called LFN Booking Table, is introduced in order to keep track of access authorization in the transient state of files entering or leaving the File Catalogue. Due to a simplification of the original Access Envelope mechanism for xrootd-protocol-based storage systems, fundamental computational improvements of the mechanism were achieved as well as an up to 50% reduction of the credential's size. By extending the access protocol with signed status messages from the underlying storage system, the File Catalogue receives trusted information about a file's size and checksum and the protocol is no longer dependent on client trust. Altogether, the revised design complies with atomic and consistent transactions and allows for accountable, authentic, and traceable file operations. This paper describes these changes as part and beyond the development of AliEn version 2.19.

    Introduction. In the first 48 hours of ventilating patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), a multipronged approach including packed red blood cell (PRBC) transfusion is undertaken to maintain oxygen delivery. Hypothesis. We hypothesized children with ALI/ARDS transfused within 48 hours of initiating mechanical ventilation would have worse outcome. The course of 34 transfused patients was retrospectively compared to 45 nontransfused control patients admitted to the PICU at Helen DeVos Children's Hospital between January 1st 2008 and December 31st 2009. Results. Mean hemoglobin (Hb) prior to transfusion was 8.2 g/dl compared to 10.1 g/dl in control. P/F ratio decreased from 135.4 ± 7.5 to 116.5 ± 8.8 in transfused but increased from 148.0 ± 8.0 to 190.4 ± 17.8 (P Fisher exact P < 0.282. Conclusion. This study suggests that early transfusions of patients with ALI/ARDS were associated with increased ventilatory needs.

    Full Text Available Visali Ali Çelebi is one of the XVIth century poets. On the basis of the poet’s work, limited information of his life can be reached. Of this kind of information is that Visali’s name was Ali and hi lived in the time of Suleiman the Magnificent. Poet’s work entitled “Mevlid-i Fahr-i Kâ’inât Muhammedini’l-Mustafâ” is a work composed in the form of mawlid that dealt with the birth of the Prophet, his childhood until seven years of age and some miracles taking place in this period. The only known manuscript copy of Visali Mevlidi is recorded in Türk Dil Kurumu Kütüphanesi, manuscript A/99 numbered. Though the mawlidmost of which was written in the masnawi form of verse, in order toavoid monotony and catch the attention of readers, the verses in theform of qasida/gazel were interspersed throughout text. In the work,intensely, Fâ‘ilâtün Fâ‘ilâtün Fâ‘ilün aruz prosody was used. In theparts written in verse, the language becomes more difficult. It can besaid that in the parts written in the form of masnawi, a plainer lenguageis used. Nevertheless, Arabic-Persian words and phrases are also seenin the Masnawis. In the Mawlid, there also existed completely Arabic orPersian verses. Considering these features, poet’s style and his power inthe field of poetry, it can be said that the work is not simple and fluent.The fat that Mawlid was suddenly finished in the childhood period ofthe Prophet gives the impression that the works was left half finished.However, when the work is compared with other texts written in theform of mawlid, with 1715 verses, it can be categorized among thevoluminous works. In this article, after giving some information aboutthe form and contents of Visali Ali Çelebi’s Mawlid, the transliteratedtext of the only copy of work we could find so far has been presented.

  11. ATP-dependent recruitment of export factor Aly/REF onto intronless mRNAs by RNA helicase UAP56.

    Loading of export factors onto mRNAs is a key step in gene expression. In vertebrates, splicing plays a role in this process. Specific protein complexes, exon junction complex and transcription/export complex, are loaded onto mRNAs in a splicing-dependent manner, and adaptor proteins such as Aly/REF in the complexes in turn recruit mRNA exporter TAP-p15 onto the RNA. By contrast, how export factors are recruited onto intronless mRNAs is largely unknown. We previously showed that Aly/REF is preferentially associated with intronless mRNAs in the nucleus. Here we show that Aly/REF could preferentially bind intronless mRNAs in vitro and that this binding was stimulated by RNA helicase UAP56 in an ATP-dependent manner. Consistently, an ATP binding-deficient UAP56 mutant specifically inhibited mRNA export in Xenopus oocytes. Interestingly, ATP activated the RNA binding activity of UAP56 itself. ATP-bound UAP56 therefore bound to both RNA and Aly/REF, and as a result ATPase activity of UAP56 was cooperatively stimulated. These results are consistent with a model in which ATP-bound UAP56 chaperones Aly/REF onto RNA, ATP is then hydrolyzed, and UAP56 dissociates from RNA for the next round of Aly/REF recruitment. Our finding provides a mechanistic insight into how export factors are recruited onto mRNAs.

They recall the individualsthey consubstantiated with Islam by heroic stories in verbal custom. Inthis praxis especially the son in law of Prophet Muhammed, first fourCaliphs and the friends of Prophet have become indispensable part ofthese legendary stories. In the legendary stories which our workincludes, the heroic, warrior and courageous side of Ali have shown asbeing a son in law of Prophet and father of Hasan and Hussein.Thistradition has written down by the works of Islamic Era of TurkishHistory. One of the “Cenknâmes” which Ali's braveness and courageoushas mention is “Destan-ı Ejderha”, The Legend Of Dragon. The legendhas written in the manner of "masnavi" and also it has some features oftale and legend genre.In this work namely “Destan-ı Ejderha” a dragon which Muslimscame to place of Prophet Muhammed in order to complain of it and awar which was fought between dragon and a group of “sahabe” underthe leadership of Ali by the assignment of Prophet Muhammed and thedefeat of dragon were mentioned. At the work Ali combines fantasticpowers in his heroic personality therefore withstands against dragonwhich was symbolized as an enemy of the religion and Ali has apersonality that is not avoid to struggle. In the legend Muslims wereaimed to encourage to “gaza” by underlining Ali’s face up of the death.Also it is aimed to obtain an idea that the true religion is Islam and alsoto make the ideal of gaza and jihad by the pointing the rebellious oneswill be eradicated in a pathetic way.In our work primarily we have compared the copies by collectedthe exemplars of “The Legend of Dragon” then tried to expose theoriginal text.

The course of 34 transfused patients was retrospectively compared to 45 nontransfused control patients admitted to the PICU at Helen DeVos Children’s Hospital between January 1st 2008 and December 31st 2009. Results. Mean hemoglobin (Hb prior to transfusion was 8.2 g/dl compared to 10.1 g/dl in control. P/F ratio decreased from 135.4±7.5 to 116.5±8.8 in transfused but increased from 148.0±8.0 to 190.4±17.8 (P<0.001 in control. OI increased in the transfused from 11.7±0.9 to 18.7±1.6 but not in control. Ventilator days in the transfused were 15.6±1.7 versus 9.5±0.6 days in control (P<0.001. There was a trend towards higher rates of MODS in transfused patients; 29.4% versus 17.7%, odds ratio 1.92, 95% CI; 0.6–5.6 Fisher exact P<0.282. Conclusion. This study suggests that early transfusions of patients with ALI/ARDS were associated with increased ventilatory needs.

    Innovation and violation of ordinary norms in the form of poem are among the resources to which the poet may resort in the process of poem composition. In effect, these resources can provide the poets with a unique style. As long as the poet observes unity and coherence in his poem, his innovation will enable him to avoid repeated poems. Mohammad Ali Bahmani is one of the contemporary lyricists who has made an efficient use of innovation in the form of sonnet in an attempt to reserve his discourse chain. The present study tries to investigate different types of Bahmani’s innovation in the form of sonnet.

    Full Text Available Remote sensing has more advantages than the traditional methods of land surface water (LSW mapping because it is a low-cost, reliable information source that is capable of making high-frequency and repeatable observations. The normalized difference water indexes (NDWIs, calculated from various band combinations (green, near-infrared (NIR, or shortwave-infrared (SWIR, have been successfully applied to LSW mapping. In fact, new NDWIs will become available when Advanced Land Imager (ALI data are used as the ALI sensor provides one green band (Band 4, two NIR bands (Bands 6 and 7, and three SWIR bands (Bands 8, 9, and 10. Thus, selecting the optimal band or combination of bands is critical when ALI data are employed to map LSW using NDWI. The purpose of this paper is to find the best performing NDWI model of the ALI data in LSW map. In this study, eleven NDWI models based on ALI, Thematic Mapper (TM, and Enhanced Thematic Mapper Plus (ETM+ data were compared to assess the performance of ALI data in LSW mapping, at three different study sites in the Yangtze River Basin, China. The contrast method, Otsu method, and confusion matrix were calculated to evaluate the accuracies of the LSW maps. The accuracies of LSW maps derived from eleven NDWI models showed that five NDWI models of the ALI sensor have more than an overall accuracy of 91% with a Kappa coefficient of 0.78 of LSW maps at three test sites. In addition, the NDWI model, calculated from the green (Band 4: 0.525–0.605 μm and SWIR (Band 9: 1.550–1.750 μm bands of the ALI sensor, namely NDWIA4,9, was shown to have the highest LSW mapping accuracy, more than the other NDWI models. Therefore, the NDWIA4,9 is the best indicator for LSW mapping of the ALI sensor. It can be used for mapping LSW with high accuracy.

    Using the particle swarm optimization algorithm combined with first-principles methods, we explore the diagram of AlY alloy up to 250 GPa. It is found that AlDy phase, rather than the experimentally observed B2 phase, is the most stable structure at 0 K and 0–20 GPa. However, our results show that B2 phase can exist as a stable phase at 20–27.6 GPa. At higher pressure, four new high-pressure phases with Cmcm-I, Cmcm-II, I4/mmm and P4/nmm structure are identified for the first time. The hardness, elastic and thermodynamic properties of the newly found phases are investigated and compared with B2 phase. The calculated hardness of AlDy, Cmcm-I, Cmcm-II, I4/mmm and P4/nmm phases is in the range of 7–9 GPa, higher than that of B2 phase. In addition, it is found that AlDy phase is a brittle material at 0 GPa, which changes to a ductile material above 12 GPa. Except for AlDy phase, all the other AlY compounds exhibit completely ductile behavior under pressure. Compared with the other phases, B2 phase is found to have the best ductility and the largest elastic anisotropy over the whole pressure investigated. Moreover, all AlY intermetallics exhibit a nearly elastic isotropy in compressibility but a comparatively large elastic anisotropy in shear. The structural stability, electronic structure, bulk and shear modulus, Debye temperature as well as sound velocities of AlY alloy under pressure are also deeply discussed. - Graphical abstract: Pressure-induced phase transition of AlY alloy up to 250 GPa. - Highlights: • The diagram of AlY alloy was explored and four new stable phases were predicted. • B2 phase shows the largest ductility and elastic anisotropy among AlY alloys. • All AlY alloys exhibit ductile behavior except for AlDy phase under pressure. • All AlY alloys show strong isotropy in compressibility and anisotropy in shear.

    2012-08-01

    In this study, the potential of EO-1 Advanced Land Imager (ALI) radiometer for land cover and especially burnt area mapping from a single image analysis is investigated. Co-orbital imagery from the Landsat Thematic Mapper (TM) was also utilised for comparison purposes. Both images were acquired shortly after the suppression of a fire occurred during the summer of 2009 North-East of Athens, the capital of Greece. The Maximum Likelihood (ML), Artificial Neural Networks (ANNs) and Support Vector Machines (SVMs) classifiers were parameterised and subsequently applied to the acquired satellite datasets. Evaluation of the land use/cover mapping accuracy was based on the error matrix statistics. Also, the McNemar test was used to evaluate the statistical significance of the differences between the approaches tested. Derived burnt area estimates were validated against the operationally deployed Services and Applications For Emergency Response (SAFER) Burnt Scar Mapping service. All classifiers applied to either ALI or TM imagery proved flexible enough to map land cover and also to extract the burnt area from other land surface types. The highest total classification accuracy and burnt area detection capability was returned from the application of SVMs to ALI data. This was due to the SVMs ability to identify an optimal separating hyperplane for best classes' separation that was able to better utilise ALI's advanced technological characteristics in comparison to those of TM sensor. This study is to our knowledge the first of its kind, effectively demonstrating the benefits of the combined application of SVMs to ALI data further implying that ALI technology may prove highly valuable in mapping burnt areas and land use/cover if it is incorporated into the development of Landsat 8 mission, planned to be launched in the coming years.

  8. Reconnectionless CME eruption: putting the Aly-Sturrock conjecture to rest

    Rachmeler, L A; Kankelborg, C C

    2008-01-01

    We demonstrate that magnetic reconnection is not necessary to initiate fast CMEs. The Aly-Sturrock conjecture states that the magnetic energy of a given force free boundary field is maximized when the field is open. This is problematic for CME initiation because it leaves little or no magnetic energy to drive the eruption, unless reconnection is present to allow some of the field to escape without opening. Thus, it has been thought that reconnection must be present to initiate CMEs. This theory has not been subject to rigorous numerical testing because conventional MHD numerical models contain numerical diffusion, which introduces uncontrolled numerical reconnection. We use a quasi-Lagrangian simulation technique to run the first controlled experiments of CME initiation in the complete lack of reconnection. We find that a flux rope confined by an arcade, when twisted beyond a critical amount, can escape to an open state, allowing some of the surrounding arcade to shrink and releasing magnetic energy from the ...

    The File Access Monitoring Service (FAMoS) leverages the information stored in the central AliEn file catalogue, which describes every file in a Unix-like directory structure, as well as metadata on file location and its replicas. In addition, it uses the access information provided by a set of API servers, used by all Grid clients to access the catalogue. The main functions of FAMoS are to sort the file accesses by logical groups, access time, user and storage element. The collected data identifies rarely used groups of files, as well as those with high popularity over different time periods. This information can be further used to optimize file distribution and replication factors, thus increasing the data processing efficiency. The paper describes the FAMoS structure and user interface and presents the results obtained in one year of service operation.

    Full Text Available This article deals with Habsburg efforts to eliminate the ottoman naval threat by employing clandestine measures and undertaking covert operations. Realizing the danger that the ottoman fl and corsairs created for their defenses, the Habsburg secret service dispatched a number of go-betweens in order to remind Uluc Ali of his Christian past and obligations to his true monarch and thus convince him to switch allegiances. The Habsburgs also tried to arrange the assassination of this dangerous corsair who reached the zenith of his power as the ottoman Grand Admiral. While the effi of Habsburg secret service demonstrate us the strength of circum-Mediterranean information gathering mechanisms and epistolary networks, the attempts of assassination and defection point to an understudied aspect of inter-imperial rivalries: secret diplomacy.

  13. The DUB-ious lack of ALIS in Salmonella infection: a Salmonella deubiquitinase regulates the autophagy of protein aggregates.

    Ubiquitinated aggregates are formed in eukaryotic cells in response to several external stimuli, including exposure to bacterial lipopolysaccharide (LPS). Although Salmonella enterica serovar Typhimurium (S. Typhimurium) LPS has been shown to induce aggresome-like induced structures (ALIS) in macrophages, these have not been described in S. Typhimurium-infected macrophages. Given that LPS is present in infection, this suggests that S. Typhimurium might suppress the formation of ALIS. We found that S. Typhimurium induces the formation of ubiquitinated aggregates in epithelial cells and macrophages, but that their presence is masked by the deubiquitinase (DUB) activity of the S. Typhimurium virulence protein, SseL. SseL deubiquitinates SQSTM1/p62-bound proteins found in S. Typhimurium-induced aggregates and ALIS, and reduces the recruitment of autophagic components. While the functions of ALIS and other ubiquitinated aggregates remain unclear, they serve to sequester cytosolic proteins under a variety of stress conditions and are suggested to be involved in host immune defense. During infection, the deubiquitinase activity of SseL reduces autophagic flux in infected cells and favors bacterial replication. This is a new example of how a bacterial pathogen counteracts the autophagy pathway through the action of a translocated virulence protein.

During Mehmet Yazar’s presidency period of TOBB (27 May 1979 – 4 April 1985 relationship between TOBB and Mother Land Party (ANAP became problematic, and in contrast to the previous periods the TOBB became an independent foundation and gained significant contributions in being a group of interest and reached a substantial economical power. In Ali Coskun’s presidency period of TOBB (4 June 1986 – 30 May 1990, on the other hand, one might see that ANAP dominated the TOBB, and TOBB lost its independence and couldn’t make significant proceedings in being a group of interest. In the same period, ANAP government made steps in direction of requests from the TOBB. As in the previous periods, during Ali Coskun’s presidency period a lot of people entered policy from the central-right parties (ANAP and True Path Party, DYP. Aim of the present study was to discuss the relationship between political power and Union of Chambers during Ali Coskun’s presidency period of TOBB and Ali Coskun’s presidency period’s differences from and similarities with the previous periods.

He was there as an invited speaker and he also chaired my session. After my session we had a chance to chat on our way to the restaurant where the banquet was held.  Even though it was the first time we hadmet, he was very kind to me.  He was there with his wife Firoza (Leena Ali. They looked great together.  Family is the most important part of our lives.  It was immediately apparent to me that Professor Ali, apart from being an outstanding statistician and a great teacher, is also a dedicated husband, father and grandfather. We have always kept in touch since our first meeting. I am very lucky to have had a chance to recently collaborate with him in a research paper. It is also a great honor for me to have been asked to serve as a guest editor for this special issue and to be able to be part of this undertaking to celebrate Dr. Ali’s 75th birthday anniversary. To some people, age is only an indicator of the year they were born but inside they feel much younger. Professor Ali is onesuch person who not only looks very young both physically and emotionally for his age but who also has the personality and mentality of a very active younger person. That is why I have chosen the title "Mir Masoom Ali: A Distinguished and Dedicated Statistician Who Never Gets Old - Even at Seventy-Five."

    A major alginate lyase, FlAlyA, was purified from the periplasmic fraction of an alginate-assimilating bacterium, Flavobacterium sp. strain UMI-01. FlAlyA showed a single band of ~30 kDa on SDS-PAGE and exhibited the optimal temperature and pH at 55 °C and pH 7.7, respectively. Analyses for substrate preference and reaction products indicated that FlAlyA was an endolytic poly(mannuronate) lyase (EC 4.2.2.3). A gene fragment encoding the amino-acid sequence of 288 residues for FlAlyA was amplified by inverse PCR. The N-terminal region of 21 residues except for the initiation Met in the deduced sequence was predicted as the signal peptide and the following region of six residues was regarded as propeptide, while the C-terminal region of 260 residues was regarded as the polysaccharide-lyase-family-7-type catalytic domain. The entire coding region for FlAlyA was subjected to the pCold I—Escherichia coli BL21(DE3) expression system and ~eight times higher yield of recombinant FlAlyA (recFlAlyA) than that of native FlAlyA was achieved. The recFlAlyA recovered in the periplasmic fraction of E. coli had lost the signal peptide region along with the N-terminal 3 residues of propeptide region. This suggested that the signal peptide of FlAlyA could function in part in E. coli. PMID:25153766

    Full Text Available A major alginate lyase, FlAlyA, was purified from the periplasmic fraction of an alginate-assimilating bacterium, Flavobacterium sp. strain UMI-01. FlAlyA showed a single band of ~30 kDa on SDS-PAGE and exhibited the optimal temperature and pH at 55 °C and pH 7.7, respectively. Analyses for substrate preference and reaction products indicated that FlAlyA was an endolytic poly(mannuronate lyase (EC 4.2.2.3. A gene fragment encoding the amino-acid sequence of 288 residues for FlAlyA was amplified by inverse PCR. The N-terminal region of 21 residues except for the initiation Met in the deduced sequence was predicted as the signal peptide and the following region of six residues was regarded as propeptide, while the C-terminal region of 260 residues was regarded as the polysaccharide-lyase-family-7-type catalytic domain. The entire coding region for FlAlyA was subjected to the pCold I—Escherichia coli BL21(DE3 expression system and ~eight times higher yield of recombinant FlAlyA (recFlAlyA than that of native FlAlyA was achieved. The recFlAlyA recovered in the periplasmic fraction of E. coli had lost the signal peptide region along with the N-terminal 3 residues of propeptide region.

    The DCA (Drug Control Authority), Malaysia, has implemented the phase 3 registration of traditional medicines on 1 January 1992, with special emphasis on the quality, efficacy, and safety (including the presence of heavy metals) in all pharmaceutical dosage forms of traditional medicine preparations. As such, a total of 100 products in various pharmaceutical dosage forms of a herbal preparation, containing Tongkat Ali, were analyzed for mercury content using cold vapor atomic absorption spectrophotometer. Results showed that 36% of the above products possessed 0.52 to 5.30 ppm of mercury and, therefore, do not comply with the quality requirement for traditional medicines in Malaysia. Out of these 36 products, 5 products that possessed 1.05 to 4.41 ppm of mercury were in fact have already registered with the DCA, Malaysia. However, the rest of the products that contain 0.52 to 5.30 ppm of mercury still have not registered with the DCA, Malaysia. Although this study showed that only 64% of the products complied with the quality requirement for traditional medicines in Malaysia pertaining to mercury, they cannot be assumed safe from mercury contamination because of batch-to-batch inconsistency.

    Currently, the commercial market offers several tools for digital documentation of historic sites and buildings. Photogrammetry and laser scanning play a fundamental role in the acquisition of metric information, which is then processed to generate reliable records particularly useful also in the built heritage conservation field. Although potentially very fast and accurate, such techniques require expert operators to produce reliable results, especially in the case of complex and large sites. The aim of this paper is to present the digital workflow developed for data acquisition and processing of the Shaikh Isa Bin Ali house in Muharraq, Bahrain. This historic structure is an outstanding example of Bahrain architecture as well as tangible memory of the country history, with strong connotations in the Bahrain cultural identity. The building has been documented employing several digital techniques, including: aerial (drone) and terrestrial photogrammetry, rectifying photography, total station and laser scanning. The documentation project has been developed for the Bahrain Authority for Culture and Antiquities (BACA) by a multidisciplinary team of experts from Carleton Immersive Media Studio (CIMS, Carleton University, Canada) and Gicarus Lab (Politecnico di Milano, Italy).

    As a consequence of the novel therapeutic option of mechanical ventilation in early intensive care medicine, the acute respiratory distress syndrome (ARDS) was defined as a disease entity of its own representing the most severe form of acute lung injury (ALI). Since its first description four decades ago, our knowledge about the aetiology, physiology, histology and epidemiology of this lethal pulmonary complication of severe acute diseases such as pneumonia or sepsis has been increasing steadily. The initial major therapeutic advances were due to improvements in intensive care medical procedures and monitoring. The large ARDS Network clinical trial on the magnitude of tidal volume impressively demonstrated the feasibility of targeted clinical trials in patients with ARDS that provide robust evidence in this field. This clinical trial, as well as following large-scale trials in ARDS patients, led to significant changes of ventilation therapy and therapeutic strategies that improve the outcome of this disease entity. Advances in the standardisation of care for ARDS patients involving innovative therapeutic procedures such as extracorporeal gas exchange systems will lead to a further improvement in ARDS management and outcome. Modern pulmonary medicine can play a pivotal role in this process and can contribute its rich experiences in all areas of the respiratory system.

    Full Text Available Teaching language as a second or foreign language, undoubtedly, is so demanding and seeking to find methods for facilitating this prominent practice whets the appetite of any practitioner who works in this field. Research shows that using drama in the classroom as a means of teaching helps students learn socially, academically, and developmentally. This study was an attempt to determine the effect of dramatized instruction on the speaking ability of EFL learners of Imam Ali University. Sixty EFL male students at the intermediate level participated in the study. Their age range was 19-22. Two instruments were utilized in this study; pretest, and posttest.  The data were analyzed through t-test. The data analysis indicated that the mean scores of the experimental group students (M = 72.80 were significantly different (3.29>2; df = 58 from the control group students (M = 65.39. In other words, the experimental group outperformed the control group in the posttest significantly. Moreover, the findings indicated that dramatized instruction does have a great effect on the speaking skills. This study supported the idea of effectiveness of dramatized instruction on developing speaking skill and the teachers can help the learners at lower levels promote their speaking skill through dramatized instruction in EFL classes.

    The ground state binding energies of hydrogenic impurities in strained wurtzite AlxGa1-xN/GaN/AlyGa1-yN quantum wells are calculated numerically by a variational method. The dependence of the binding energy on well width, impurity location and Al concentrations of the left and right barriers is discussed, including the effect of the built-in electric field induced by spontaneous and piezoelectric polarizations. The results show that the change in binding energy with well width is more sensitive to the impurity position and barrier heights than the barrier widths, especially in asymmetric well structures where the barrier widths and/or barrier heights differ. The binding energy as a function of the impurity position in symmetric and asymmetric structures behaves like a map of the spatial distribution of the ground state wave function of the electron. It is also found that the influence on the binding energy from the Al concentration of the left barrier is more obvious than that of the right barrier.

    2011-01-01

    Full Text Available Since his first articles in Revista Brazileira published in 1895, Manuel Said Ali Ida (1860-1953 gave priority to the synchronic study of the spoken language. He argues that dynamic accent (greater voice intensity and musical accent (pitch affect the meaning of the clause and demonstrate the interdependence of the phonetic, syntactic and semantic levels. In Portuguese, the word pronounced with most stress contains the main idea and is usually placed at the end of the clause. A change of word order or stress replacement draws the listener’s attention and facilitates the identification of new information by means of intonation. The introduction of phonetic criteria as a parameter of analysis separates Said Ali from the grammatical tradition of his time, making him the precursor of Brazilian linguistics. This essay in Linguistic Historiography seeks to trace in Said Ali’s work on accent the emergence of a new field of language study.

    Full Text Available This article studies three short stories by Muhammad Ali Saeid (1950-, a writer and critic who lives in Tamrah, the Western Galilee. These stories are “The Delivery” (Al Wilādah, “Ḥayāt” (life, and “Devouring” (Iftirās, which appeared in Assadi’s Father and Son: Selected Short Fiction by Hanna Ibrahim Elias and Mohammad Ali Saeid. It examines the use of the artistic devices used in the selected short stories to highlight “female oppression” as well as the linkage between feminism and post-colonialism, in case of Palestine. Above all, this article confirms that the profound perceptions of Saeid are reflected in his success to control his narrative techniques so artistically that he offers new arenas for academic assessments and analysis. Saeid’s observations also brighten new terrains, where divergent powers can band tunefully to battle subjugation, prejudice, and occupation.

  14. Cellular Nuclear Export Factors TAP and Aly Are Required for HDAg-L-mediated Assembly of Hepatitis Delta Virus.

    Hepatitis delta virus (HDV) is a satellite virus of hepatitis B virus (HBV). HDV genome encodes two forms of hepatitis delta antigen (HDAg), small HDAg (HDAg-S), which is required for viral replication, and large HDAg (HDAg-L), which is essential for viral assembly. HDAg-L is identical to HDAg-S except that it bears a 19-amino acid extension at the C terminus. Both HDAgs contain a nuclear localization signal (NLS), but only HDAg-L contains a CRM1-independent nuclear export signal at its C terminus. The nuclear export activity of HDAg-L is important for HDV particle formation. However, the mechanisms of HDAg-L-mediated nuclear export of HDV ribonucleoprotein are not clear. In this study, the host cellular RNA export complex TAP-Aly was found to form a complex with HDAg-L, but not with an export-defective HDAg-L mutant, in which Pro(205) was replaced by Ala. HDAg-L was found to colocalize with TAP and Aly in the nucleus. The C-terminal domain of HDAg-L was shown to directly interact with the N terminus of TAP, whereas an HDAg-L mutant lacking the NLS failed to interact with full-length TAP. In addition, small hairpin RNA-mediated down-regulation of TAP or Aly reduced nuclear export of HDAg-L and assembly of HDV virions. Furthermore, a peptide, TAT-HDAg-L(198-210), containing the 10-amino acid TAT peptide and HDAg-L(198-210), inhibited the interaction between HDAg-L and TAP and blocked HDV virion assembly and secretion. These data demonstrate that formation and release of HDV particles are mediated by TAP and Aly. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    Increased levels of plasminogen activator inhibitor-1 (PAI-1) have been associated with worse outcome in ALI/ARDS. A single guanosine insertion/deletion (4G/5G) polymorphism in the promoter region of the PAI-1 gene, may play an important role in the regulation of PAI-1 expression. The objective of the study was to evaluate the effect of this polymorphism on the outcome of critically ill patients with ALI/ARDS. 52 consecutive ventilated patients with ALI/ARDS were studied. Bronchoalveolar lavage was performed within 48 hours from diagnosis. Measurement of plasma and BALF PAI-1 activity and D-dimers levels, and 4G/5G genotyping of PAI-1 were carried out. The primary outcome was 28-day mortality, and secondary outcomes included organ dysfunction and ventilator-free days. 17 patients were homozygotes for the 4G allele. Severity scores were not different between subgroups upon study enrollment. 28-day mortality was 70.6% and 42.9% for the 4G-4G and the non-4G-4G patients, respectively (p=0.06). PAI-1 activity levels and D-dimer in plasma and BALF were not significantly different between the 4G-4G and the non-4G-4G subgroups. In the multivariate analysis, genotype 4G/4G was the only variable independently associated with 28-day mortality (Odds Ratio=9.95, 95% CI: 1.79-55.28, p=0.009). Furthermore, genotype 4G/4G and plasma PAI-1 activity levels were independently negatively associated with ventilator free days (p=0.033 and p=0.008, respectively). ALI/ARDS patients, homozygous for the 4G allele of the PAI-1 gene, experienced higher 28-day mortality. This genotype was associated with a reduction in the number of days of unassisted ventilation and was inversely associated with the number of days without organ failure.

    Full Text Available The Julfa Formation in the Ali Bashi Mountains, northwest Iran, is very rich in brachiopods, particularly in its lower part, which has been dated by fusulinids and conodonts as Wuchiapingian in age. The brachiopod fauna described herein has been collected along the Main Valley section of the Ali Bashi Mountains, several hundred metres away from the historical sections described in the 1960’s and 1970’s. It comprises 39 species of the orders Productida, Orthotetida, Orthida, Rhynchonellida, Athyridida, Spiriferida, and Terebratulida, most of which are known in the coeval successions of Transcaucasia, Alborz Mountains in north Iran and in South China, confirming the Wuchiapingian age indicated by other proxies. A few of the brachiopod taxa range up into the Changhsingian Paratirolites Limestone. The shale and marly limestone at the base of the formation are dominated by semi-infaunal productids, that are progressively succeeded near the top of the lower part of the formation by a more diverse range of pedicle attached and cemented taxa, suggesting a shallowing upward trend and a shift to higher nutrient-substrates in more turbulent waters. The successive deepening trend recorded in the upper part of the Julfa Formation and in the overlying Ali Bashi Formation is very unfavourable for the brachiopods and only a few species survive, represented by small sized pediculate taxa that thrive on hardgrounds.

    We mapped tropical dry forest height (RMSE = 0.9 m, R2 = 0.84, range 0.6-7 m) and foliage height profiles with a time series of gap-filled Landsat and Advanced Land Imager (ALI) imagery for the island of Eleuthera, The Bahamas. We also mapped disturbance type and age with decision tree classification of the image time series. Having mapped these variables in the context of studies of wintering habitat of an endangered Nearctic-Neotropical migrant bird, the Kirtland's Warbler (Dendroica kirtlandii), we then illustrated relationships between forest vertical structure, disturbance type and counts of forage species important to the Kirtland's Warbler. The ALI imagery and the Landsat time series were both critical to the result for forest height, which the strong relationship of forest height with disturbance type and age facilitated. Also unique to this study was that seven of the eight image time steps were cloud-gap-filled images: mosaics of the clear parts of several cloudy scenes, in which cloud gaps in a reference scene for each time step are filled with image data from alternate scenes. We created each cloud-cleared image, including a virtually seamless ALI image mosaic, with regression tree normalization of the image data that filled cloud gaps. We also illustrated how viewing time series imagery as red-green-blue composites of tasseled cap wetness (RGB wetness composites) aids reference data collection for classifying tropical forest disturbance type and age.

    Full Text Available We present results of an investigation of the fine structure of the night sector diffuse auroral zone, observed simultaneously with optical instruments (ALIS from the ground and the FAST electron spectrometer from space 16 February 1997. Both the optical and particle data show that the diffuse auroral zone consisted of two regions. The equatorward part of the diffuse aurora was occupied by a pattern of regular, parallel auroral stripes. The auroral stripes were significantly brighter than the background luminosity, had widths of approximately 5 km and moved southward with a velocity of about 100 m/s. The second region, located between the region with auroral stripes and the discrete auroral arcs to the north, was filled with weak and almost homogeneous luminosity, against which short-lived auroral rays and small patches appeared chaotically. From analysis of the electron differential fluxes corresponding to the different regions of the diffuse aurora and based on existing theories of the scattering process we conclude the following: Strong pitch angle diffusion by electron cyclotron harmonic waves (ECH of plasma sheet electrons in the energy range from a few hundred eV to 3–4 keV was responsible for the electron precipitation, that produced the background luminosity within the whole diffuse zone. The fine structure, represented by the auroral stripes, was created by precipitation of electrons above 3–4 keV as a result of pitch angle diffusion into the loss cone by whistler mode waves. A so called "internal gravity wave" (Safargaleev and Maltsev, 1986 may explain the formation of the regular spatial pattern formed by the auroral stripes in the equatorward part of the diffuse auroral zone.

Both the optical and particle data show that the diffuse auroral zone consisted of two regions. The equatorward part of the diffuse aurora was occupied by a pattern of regular, parallel auroral stripes. The auroral stripes were significantly brighter than the background luminosity, had widths of approximately 5 km and moved southward with a velocity of about 100 m/s. The second region, located between the region with auroral stripes and the discrete auroral arcs to the north, was filled with weak and almost homogeneous luminosity, against which short-lived auroral rays and small patches appeared chaotically. From analysis of the electron differential fluxes corresponding to the different regions of the diffuse aurora and based on existing theories of the scattering process we conclude the following: Strong pitch angle diffusion by electron cyclotron harmonic waves (ECH) of plasma sheet electrons in the energy range from a few hundred eV to 3 4 keV was responsible for the electron precipitation, that produced the background luminosity within the whole diffuse zone. The fine structure, represented by the auroral stripes, was created by precipitation of electrons above 3 4 keV as a result of pitch angle diffusion into the loss cone by whistler mode waves. A so called "internal gravity wave" (Safargaleev and Maltsev, 1986) may explain the formation of the regular spatial pattern formed by the auroral stripes in the equatorward part of the diffuse auroral zone.

    Full Text Available The mineralization processes in the Peloritani Belt (Southern Sector of the Calabria- Peloritani Arc, related to Pre-Variscan intracontinental rifting, produced sedex-type Pb, Zn, F (Ag, Cu, W (As, Sb ores. This paper focuses on the metalliferous stratabound mineralization outcropping in the Ali' area (Tripi locality. It is part of sulphide ores, concordant with the regional foliation of the hosting unit (Fv2, very widespread in the Mandanici Unit (MaU. This unit is characterized by a Variscan low-P, polyphasic and plurifacial metamorphic overprint involving the basement. This metamorphic overprint exhibits a prograde zoning, from a chlorite zone of greenschist facies to an oligoclase-almandine zone of amphibolite facies. The metalliferous mineral association is formed by galena, sphalerite, pyrite, chalcopyrite, arsenopyrite and covellite. Quartz and fluorite among non-metalliferous minerals are predominant. Some minerals like quartz, fluorite, galena, sphalerite and pyrite are present in two generations, the second of which can be related to intense hydrothermal activity involving the whole Peloritani Belt. Trace-element contents of sulphide ores detected by Atomic Absorption and Inductively Coupled Plasma-Mass Spectrometry on powdered and selected samples of minerals have been determined. Major elements have been analyzed by Scanning Electron Microscopy. The Ag content is quite high in galena, relative to the same mineral of other Peloritani deposits in which this content is around 1000 ppm. Galena shows a high content of Sb (x=621 and lower values of Cd (x=132 and Cu (x=108 whereas in sphalerite the Sb content (x=134 is lower than Cd (x=1118 and Cu (x=1127. Mn is scarcely present in sphalerite, while galena shows higher contents. Fe content in sphalerite is about 6%, in agreement with Pressure-Temperature conditions of the Unit.

    The Landsat-7 Enhanced Thematic Mapper Plus (ETM+) is the sensor payload on the Landsat-7 satellite imager (launched on April 15th, 1999) that is a derivative of the Landsat-4 and 5 Thematic Mapper (TM) land imager sensors. Scan Line Corrector (SLC) malfunctioning appeared onboard on May 31, 2003. The SLC-Off problem was caused by failure of the SLC which compensates for the forward motion of the satellite [1]. As ETM+ is still capable of acquiring images with the SLC-Off mode, the need of applying new techniques and using other data sources to reconstruct the missed data is a challenging for scientists and final users of remotely sensed images. One of the predicted future roles of the Advanced Land Imager (ALI) onboard the Earth Observer One (EO-1) is its ability to offer a potential technological direction for Landsat data continuity missions [2]. In this regard more than the purposes of the work as fabricating the gapped area in the ETM+ the attempt to evaluate the ALI imagery ability is another noticeable point in this work. In the literature there are several techniques and algorithms for gap filling. For instance local linear histogram matching [3], ordinary kriging, and standardized ordinary cokriging [4]. Here we used the Regression Based Data Combination (RBDC) in which it is generally supposed that two data sets (i.e. Landsat/ETM+ and EO-1/ALI) in the same spectral ranges (for instance band 3 ETM+ and band 4 ALI in 0.63 - 0.69 μm) will have meaningful and useable statistical characteristics. Using this relationship the gap area in ETM+ can be filled using EO-1/ALI data. Therefore the process is based on the knowledge of statistical structures of the images which is used to reconstruct the gapped areas. This paper presents and compares four regression based techniques. First two ordinary methods with no improvement in the statistical parameters were undertaken as Scene Based (SB) and Cluster Based (CB) followed by two statistically developed algorithms

    Full Text Available Abstract Background Despite consensus criteria, diagnosing acute lung injury, or its more severe form acute respiratory distress syndrome (ALI/ARDS remains challenging. Adding objective measures, such as plasma levels of biological markers could facilitate recognition of ALI/ARDS. This study was designed to assess and compare the diagnostic accuracy of biological markers for ALI/ARDS with ventilator-associated pneumonia (VAP. Methods We performed serial measurements of Clara cell protein (CC16, soluble receptor for advanced glycation end products (sRAGE, surfactant protein D (SP-D and Krebs von den Lungen (KL-6 in plasma of patients with VAP and mechanically ventilated control patients without VAP. ALI/ARDS was diagnosed using the criteria of the North-American European consensus conference. Results Thirty-seven patients were enrolled - 22 patients with VAP and 15 control patients. Ten patients with pneumonia met the ALI/ARDS consensus criteria. Control patients never met these criteria. Plasma CC16 had a good diagnostic capacity for ALI/ARDS as shown by the receiver operating characteristic curve with an area under the curve of 0.91 (95% confidence interval (CI 0.79 - 1.00; p p = 0.02. The diagnostic accuracies of KL-6 and sRAGE were low. Conclusion Plasma CC16 seems a potential biological marker for ALI/ARDS in patients with VAP. Plasma levels of sRAGE, SP-D and KL-6 have limited discriminative power for diagnosing ALI/ARDS in VAP.

    Hyperspectral data coverage from the EO-1 Hyperion sensor was useful for calibrating Advanced Land Imager (ALI) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images of a volcanic terrane area of the Chilean-Bolivian Altiplano. Following calibration, the ALI and ASTER datasets were co-registered and joined to produce a 13-channel reflectance cube spanning the Visible to Short Wave Infrared (0.4-2.4 ??m). Eigen analysis and comparison of the Hyperion data with the ALI + ASTER reflectance data, as well as mapping results using various ALI+ASTER data subsets, provided insights into the information dimensionality of all the data. In particular, high spectral resolution, low signal-to-noise Hyperion data were only marginally better for mineral mapping than the merged 13-channel, low spectral resolution, high signal-to-noise ALI + ASTER dataset. Neither the Hyperion nor the combined ALI + ASTER datasets had sufficient information dimensionality for mapping the diverse range of surface materials exposed on the Altiplano. However, it is possible to optimize the use of the multispectral data for mineral-mapping purposes by careful data subsetting, and by employing other appropriate image-processing strategies.

    The thermal behaviour, mineralogy, texture and micro-structure of the original rocks used as raw materials in the manufacture of ceramics of the potter community in Fran Ali (Oued Laou, Tetouan, Morocco) were studied. The original rocks of the alteration deposit are metapelites and altered philites from the Units Malaguide-Gomaride in the Baetic-Rifian mountain system. The techniques used by local potters and the water used to prepare the ceramic bodies were also studied. Original rocks are metapelites or filadios and raw materials belong to levels caused by exogenous or supergene alteration (quartz-illite and chlorite type clays). The ceramics studied by microscopy exhibit anisotropy. (Author) 15 refs.

    Objective To evaluate the value and feasibility of plasma vWF: Ag and protein C activity in the diagnosis and prognosis in ALI/ARDS patients. Methods The clinical data of 49 ALI/ARDS patients and 21 non - ALI / ARDS patients was collected and evaluated with APACHE II score system and lung injury score(LIS). Furthermore, ALI/ARDS patients were divided into two groups by prognosis, etiology, and organ failure number ( nonpulmonary). Mortality of every group was collected. Plasma vWF:Ag and protein C activity of patients were detected and evaluated. The value of plasma vWF:Ag and protein C activity in diagnosis of ALI/ARDS was analyzed by receiver operator characteristic( ROC) curve. Results Compared with non - ALI/ARDS group, the mortality and LIS score of ALI/ARDS group were significantly increased, PaO2/FiO2 was significantly declined. Plasma vWF: Ag (104% -752% ) in ALI / ARDS group was higher (P = 0.026), but PC activity ( 14% -125%) was significantly lower (P =0. 002). In the ALI/ARDS patients, plasma vWF: Ag of dead group, infected group and 3: 2 organ failure group were significantly higher than their control group; while PC activity of the three groups were greatly lower than their control groups. ROC curve analysis showed that PC activity was better in prediction ALI/ARDS (AUC = 0.709,95% CI:0.588 -0. 811 ,P =0. 0016) ,and the sensitivity and specificity were respectively 77. 75% and 57. 14% when PC activity ≤83% ; but vWF: Ag was poor in prediction ALI/ARDS ( AUC =0. 584,95% CI:0. 460-0. 701, P=0.2426). Conclusion Elevated plasma vWF;Ag and declined PC activity are associated with an increased risk of death and worse prognosis in ALI/ARDS patients. The accuracy of plasma PC activity to predict ALI/ARDS was better, but it is a controversial conclusion in prediction ALI/ARDS by plasma vWF:Ag.%目的 探讨血浆血管性血友病因子抗原(vWF:Ag)、蛋白C(PC)活性在急性肺损伤(ALI)/急性呼吸窘迫综合征(ARDS)患者早期诊断

    Taiwan mountains are severely affected each year by landslides, rock falls, and debris flows where the roads system suffer the most critical consequences. Among all mountain highways, Ali Highway, located into the main entrance of Alishan Mountain region, is one of the most landslide-prone areas in southern Taiwan. During the typhoon season, between May and August, the probability of occurrence of mass movements is at higher level than usual seeing great erosion rates. In fact, during Typhoon Morakot, in 2009, the intense rainfall caused abrupt interruption of the circulation for three months triggering several landslides (Liu et al. 2012). The topographic features such as slope, roughness and curvature among others have been extracted from 1 m DTM derived by a LiDAR dataset (collected in 2015) to investigate the slope failures along the Ali Mountain Highway. The high-resolution DTM highlighted that the hydrogeomorphological (e.g. density of stream, the distance from the ridge and terrain) features are one of the most influencing factors affecting the change and the instability of the slopes. To detect the landslide area, the decision tree classifier and the random forest algorithm (RF) have been adopted. The results provided a suitable analysis of the area involved in the failure. This will be a useful step in the understanding (and management) landslide processes of study area.

But the domain of concurrent programming has become a field for highly skilled experts, as the implementation of multithreading is difficult, error prone and labor intensive. A full re-implementation for parallel execution of existing offline frameworks, like AliRoot in ALICE, is thus unaffordable. An alternative method, is to use a semi-automatic source-to-source transformation for getting a simple parallel design, with almost no interference between threads.

    Herpes simplex virus 1 (HSV-1) protein ICP27 enables viral mRNA export by accessing the cellular mRNA export receptor TAP/NXF, which guides mRNA through the nuclear pore complex. ICP27 binds viral mRNAs and interacts with TAP/NXF, providing a link to the cellular mRNA export pathway. ICP27 also interacts with the mRNA export adaptor protein Aly/REF, which binds cellular mRNAs and also interacts with TAP/NXF. Studies using small interfering RNA (siRNA) knockdown indicated that Aly/REF is not required for cellular mRNA export, and similar knockdown studies during HSV-1 infection led us to conclude that Aly/REF may be dispensable for viral RNA export. Recently, the structural basis of the interaction of ICP27 with Aly/REF was elucidated at atomic resolution, and it was shown that three ICP27 residues, W105, R107, and L108, interface with the RNA recognition motif (RRM) domain of Aly/REF. Here, to determine the role the interaction of ICP27 and Aly/REF plays during infection, these residues were mutated to alanine, and a recombinant virus, WRL-A, was constructed. Virus production was reduced about 10-fold during WRL-A infection, and export of ICP27 protein and most viral mRNAs was less efficient. We conclude that interaction of ICP27 with Aly/REF contributes to efficient viral mRNA export.

The charts of patients who had undergone a lumbar puncture were studied and cases of meningitis were selected. The related data was collected and analyzed with SPSS version 16.ResultsA total of 681 patients with FS were known from which 422 (62% lumbar punctures (LP were done. Meningitis (bacterial or aseptic was identified in 19 cases (4.5%, 95% CI 2.9–6.9 by Wilson- Score internal and bacterial meningitis in 7 (1.65%, 95% CI 0.8–3.3. None of the patients with bacterial meningitis had meningeal irritation signs. Complex FS, first attack of FS, and impaired consciousness were more common in patients with meningitis when compared to non- meningitis patients.ConclusionMeningitis is more common in patients less than 18 months presenting with FS; however, complex features of seizures, first attack of FS, or impaired consciousness seem significant risk factors for meningitis in these children and an LP should be considered in this situation. ReferencesKimia A, Ben-Joseph EP, Rudleo T, et al.

    Cette étude concerne les techniques de recuit laser (LTP) et de dopage laser direct (GILD) de jonctions ultra-minces, nécessaires à la fabrication des composants microélectroniques du futur (générations CMOS sub 0,1 μm). Des jonctions de 20 à 80 nm sont réalisées à l'aide d'un laser à excimères. Le procédé est suivi en temps réel grâce à l'analyse de la réflectivité transitoire à 675 nm. L'évolution de l'activation des dopants est ensuite caractérisée par spectroscopie IR (FTIR). Les résultats obtenus permettent de caractériser les jonctions en termes d'épaisseur dopées, concentration et résistivité. Une comparaison avec des caractérisations classiques (mesures électriques de résistivité, profils SIMS) permet de valider ces mesures et de mettre en évidence l'intérêt des techniques optiques pour la caractérisation in-situ et ex-situ des couches minces dopées réalisées par laser.

    According to Sami-Ali's theoretical model the psychosomatic personality is characterised by an adaptation pathology whose main elements are the repression of imaginative thought and conformity to socio-cultural standards. This study examines adaptation pathology using the Rorschach test. The Authors have formulated a conformity index by relating kinestheses (M) and banal perceptions (BAN). The study was carried out on a sample of 41 patients suffering from ulcerous rectocolitis comprising 24 males and 17 women with a mean age of 32 years. As expected in the hypothesis 97.6% of the sample showed M values below the norm, and 68.3% had Ban values higher than normal, whereas the conformity index was positive and tendentially positive in 65.9% of cases. These findings confirm Sami-Ali's theory. Subjects with ulcerous rectocolitis form part of the adaptation pathology which characterised the psychosomatic personality, with an inverse proportionality between imaginative activity (kinesthesia below normal) and conformism (banal perceptions above the norm).

    Spectral band synthesis is a key step in the process of creating a simulated multispectral image from hyperspectral data. In this step, narrow hyperspectral bands are combined into broader multispectral bands. Such an approach has been used quite often, but to the best of our knowledge accuracy of the band synthesis simulations has not been evaluated thus far. Therefore, the main goal of this paper is to provide validation of the spectral band synthesis algorithm used in the ART software. The next section contains a description of the algorithm and an example of its application. Using spectral responses of AVIRIS, Hyperion, ALI, and ETM+, the following section shows how the synthesized spectral bands compare with actual bands, and it presents an evaluation of the simulation accuracy based on results of MODTRAN modeling. In the final sections of the paper, simulated images are compared with data acquired by actual satellite sensors. First, a Landsat 7 ETM+ image is simulated using an AVIRIS hyperspectral data cube. Then, two datasets collected with the Hyperion instrument from the EO-1 satellite are used to simulate multispectral images from the ALI and ETM+ sensors.

    Pressure dependent angle-dispersive x-ray powder diffraction measurements of alpha-phase aluminum trifluoride (α-AlF3) and separately, aluminum triiodide (AlI3) were conducted using a diamond-anvil cell. Results at 295 K extend to 50 GPa. The equations of state of AlF3 and AlI3 were determined through refinements of collected x-ray diffraction patterns. The respective bulk moduli and corresponding pressure derivatives are reported for multiple orders of the Birch-Murnaghan (B-M), finite-strain (F-f), and higher pressure finite-strain (G-g) EOS analysis models. Aluminum trifluoride exhibits an apparent isostructural phase transition at approximately 12 GPa. Aluminum triiodide also undergoes a second-order atomic rearrangement: applied stress transformed a monoclinically distorted face centered cubic (fcc) structure into a standard fcc structural arrangement of iodine atoms. Results from semi-empirical thermochemical computations of energetic materials formulated with fluorine containing reactants were obtained with the aim of predicting the yield of halogenated products.

    Full Text Available Abstract: In the context of social change, the thought of Ali Syar'ati, if seen from the perspective of its frameworks and methods,is different from the thought of other Islamic movements.On the one hand, Shari'ati’s thought opposes the Iranian authority, Shah Pahlavi, but on the other hand, it is totally different from the traditional Iranian anti-change cleric, and it is also in contrast to the radical Islamic movements that do political rebellion against the ruler.Shari'atiput up political resistance through revolutionary ideas influencing public opinion to understand Islam as a doctrine which has an emancipatory interest, that is, the belief of Islam as a school of thought and action in the fight against social and economic injustice, despotic ruler, and the fetters of culture. Efforts to comprehend Islamic meanings in modern and contextual Islamic thought presents two patterns of social changes; first is the pattern of moderatemovement and second is extreme one. The formerleads more specifically to how to implement Islamic values in the national way of life, and   sense of nationalitywithout being trapped inreligious symbols and labels, while the latter leads totheimplementation of Islamic values and symbolismand labeling whichare both considered to be important. So the former tends to take more substantive values of Islam that is essentially concerned with the purpose of realization of the ideals of Islam, while the latter tends to the enactment of Islamic lawin all aspects of community life.  الملخص: في سياق التغيير الاجتماعي، يعتقد أن فكرة علي شريعتي لها إطار وأساليب تختلف عن أساليب رواد الفكر والحركات الإسلامية الأخرى. من ناحية ،أن شريعتي يكافح ضد سلطة مستبدة في إيران، شاه بهلوي. ومن ناحية أخرى، كان مختلفا تماما عن علماء الدين

  8. Endocytosis of the Aspartic Acid/Glutamic Acid Transporter Dip5 Is Triggered by Substrate-Dependent Recruitment of the Rsp5 Ubiquitin Ligase via the Arrestin-Like Protein Aly2 ▿

    Endocytosis of nutrient transporters is stimulated under various conditions, such as elevated nutrient availability. In Saccharomyces cerevisiae, endocytosis is triggered by ubiquitination of transporters catalyzed by the E3 ubiquitin ligase Rsp5. However, how the ubiquitination is accelerated under certain conditions remains obscure. Here we demonstrate that closely related proteins Aly2/Art3 and Aly1/Art6, which are poorly characterized members of the arrestin-like protein family, mediate endocytosis of the aspartic acid/glutamic acid transporter Dip5. In aly2Δ cells, Dip5 is stabilized at the plasma membrane and is not endocytosed efficiently. Efficient ubiquitination of Dip5 is dependent on Aly2. aly1Δ cells also show deficiency in Dip5 endocytosis, although less remarkably than aly2Δ cells. Aly2 physically interacts in vivo with Rsp5 at its PY motif and also with Dip5, thus serving as an adaptor linking Rsp5 with Dip5 to achieve Dip5 ubiquitination. Importantly, the interaction between Aly2 and Dip5 is accelerated in response to elevated aspartic acid availability. This result indicates that the regulation of Dip5 endocytosis is accomplished by dynamic recruitment of Rsp5 via Aly2. PMID:20956561

    The electrical breakdown of thin films of polyphenylene oxide electrochemically deposited on stainless steel plane substrates has been studied. First it was examined the dependence of the medium surrounding the dielectric and the electrodes (nature, hydrostatic pressure) on the breakdown voltage and on its statistical distribution. Between sphere and plane electrodes, it appears that even for pressurified gases, breakdown of the film is caused by the gas breakdown. We have analysed the discharges occurring at atmosphere pressure in the test cell. Breakdown of the film occurred when the electric field due to the charge deposited on its surface was about 230 V/μm. We have also studied self-healing capacitors with PPO as a dielectric, and determined the life-time of this material. On a étudié le claquage électrique de films minces d'oxyde de polyphénylène de quelques microns d'épaisseur déposés par voie électrochimique sur un plan en acier inoxydable. L'étude a d'abord été faite en rampe de tension continue dans la géométrie d'électrodes sphèreplan, en fonction du milieu ambiant liquide ou gazeux. L'influence de la pression sur la rigidité diélectrique du matériau, les distributions statistiques de Weibull et les cratères formés au moment du claquage, dans les différents milieux et dans les deux polarités de l'électrode sphérique montrent que le claquage du matériau est causé par des décharges qui se produisent dans le milieu environnant. A partir de l'analyse quantitative de ces décharges, on propose comme critère de caractérisation de la rupture d'un matériau sounmis aux décharges, le champ créé au moment de la rupture par les charges déposées à sa surface. On a réalisé ensuite des échantillons plans > par dépôt de couches minces d'aluminium (quelques milliers d'Å d'épaisseur) sur le film de PPO. On étudie dans cette configuration la durée de vie du matériau.

    Full Text Available BACKGROUND: Peptide patterns of bronchoalveolar lavage fluid (BALF were assumed to reflect the complex pathology of acute lung injury (ALI/acute respiratory distress syndrome (ARDS better than clinical and inflammatory parameters and may be superior for outcome prediction. METHODOLOGY/PRINCIPAL FINDINGS: A training group of patients suffering from ALI/ARDS was compiled from equal numbers of survivors and nonsurvivors. Clinical history, ventilation parameters, Murray's lung injury severity score (Murray's LISS and interleukins in BALF were gathered. In addition, samples of bronchoalveolar lavage fluid were analyzed by means of hydrophobic chromatography and MALDI-ToF mass spectrometry (MALDI-ToF MS. Receiver operating characteristic (ROC analysis for each clinical and cytokine parameter revealed interleukin-6>interleukin-8>diabetes mellitus>Murray's LISS as the best outcome predictors. Outcome predicted on the basis of BALF levels of interleukin-6 resulted in 79.4% accuracy, 82.7% sensitivity and 76.1% specificity (area under the ROC curve, AUC, 0.853. Both clinical parameters and cytokines as well as peptide patterns determined by MALDI-ToF MS were analyzed by classification and regression tree (CART analysis and support vector machine (SVM algorithms. CART analysis including Murray's LISS, interleukin-6 and interleukin-8 in combination was correct in 78.0%. MALDI-ToF MS of BALF peptides did not reveal a single identifiable biomarker for ARDS. However, classification of patients was successfully achieved based on the entire peptide pattern analyzed using SVM. This method resulted in 90% accuracy, 93.3% sensitivity and 86.7% specificity following a 10-fold cross validation (AUC = 0.953. Subsequent validation of the optimized SVM algorithm with a test group of patients with unknown prognosis yielded 87.5% accuracy, 83.3% sensitivity and 90.0% specificity.

    Full Text Available The optical properties of metal-organic vapor phase epitaxy grown AlyInxGa1−x−yN quantum dot structures have been studied by time-resolved photoluminescence experiments. We investigated the recombination dynamics of the photo-exited carriers in dependence of the growth parameters such as aluminium flow and the duration of the growth interruption after the dot deposition. Our results confirm the presence of localized states, where the degree of localization is strongly dependent on the growth conditions. To describe this behavior, we propose a band structure with coupled potentials for these nanostructures. Finally, we demonstrate state filling to prove the zero-dimensional character of the strongly localized states in our quaternary quantum dots.

  4. Binding of cellular export factor REF/Aly by Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 protein is not required for efficient KSHV lytic replication.

    Li, Da-Jiang; Verma, Dinesh; Swaminathan, Sankar

    2012-09-01

    Kaposi's sarcoma-associated herpesvirus (KSHV) ORF57 protein is expressed early during lytic KSHV replication, enhances expression of many KSHV genes, and is essential for virus production. ORF57 is a member of a family of proteins conserved among all human and many animal herpesviruses that are multifunctional regulators of gene expression and act posttranscriptionally to increase accumulation of their target mRNAs. The mechanism of ORF57 action is complex and may involve effects on mRNA transcription, stability, and export. ORF57 directly binds to REF/Aly, a cellular RNA-binding protein component of the TREX complex that mediates RNA transcription and export. We analyzed the effects of an ORF57 mutation known to abrogate REF/Aly binding and demonstrate that the REF-binding mutant is impaired in activation of viral mRNAs and noncoding RNAs confined to the nucleus. Although the inability to bind REF leads to decreased ORF57 activity in enhancing gene expression, there is no demonstrable effect on nuclear export of viral mRNA or the ability of ORF57 to support KSHV replication and virus production. These data indicate that REF/Aly-ORF57 interaction is not essential for KSHV lytic replication but may contribute to target RNA stability independent of effects on RNA export, suggesting a novel role for REF/Aly in viral RNA metabolism.

    We recently reported that adoptively transferred (AT) exogenous CD4+CD25+ regulatory T cells (Tregs) to wild type (WT) mice can directly act to repress shock/sepsis induced experimental iALI and this is mediated in part by programmed cell death receptor 1 (PD-1). In this study, we further determine whether recipient mouse lacking PD-L1, one of the primary ligands for PD-1, contributes to the manipulation of the Tregs’ capacity to repress lung injury. To do this, Tregs isolated from the spleen of WT mice were AT into PD-L1−/− mice subjected to hemorrhagic shock [Hem] and subsequent to cecal ligation and puncture (CLP) to induce iALI. Samples were collected for analyses 24 hours after CLP. We found that in PD-L1−/− recipient mice, AT WT-Tregs lost the ability to reverse the development of iALI seen in WT recipient mice (i.e., no reduction of lung injury indices assessed by histology and vascular leakage; failure to decrease the lung neutrophil influx [MPO activity] or the rise in lung apoptosis [caspase 3 activity]). Also a significant increase of interlukin-1β (IL-1β) and keratinocyte-derived chemokine (KC), but no changes in IL-6, IL-10 and IL-17A levels in lung tissues were seen in these mice compared with iALI mice without AT of Tregs. Furthermore, we noted that the lung tissue tyrosine phosphatase Src homology region 2 domain-containing phosphatase 1 (SHP-1), but not SHP-2, was activated with the AT of Tregs in PD-L1−/− iALI mice. Finally, through local depletion of CD4+ T cells or CD25+ (Tregs) in the lung, prior to inducing iALI, we found that SHP-1 activation was associated with the loss of Tregs’ protective effects in vivo. Collectively, our data reveal that PD-L1 is a critical modulator of Treg’s ability to suppress iALI and this appears to involve SHP-1 activation. PMID:25057927

    In this study, a comparative analysis of capabilities of three sensors for mapping forest crown closure (CC) and leaf area index (LAI) was conducted. The three sensors are Hyperspectral Imager (Hyperion) and Advanced Land Imager (ALI) onboard EO-1 satellite and Landsat-7 Enhanced Thematic Mapper Plus (ETM+). A total of 38 mixed coniferous forest CC and 38 LAI measurements were collected at Blodgett Forest Research Station, University of California at Berkeley, USA. The analysis method consists of (1) extracting spectral vegetation indices (VIs), spectral texture information and maximum noise fractions (MNFs), (2) establishing multivariate prediction models, (3) predicting and mapping pixel-based CC and LAI values, and (4) validating the mapped CC and LAI results with field validated photo-interpreted CC and LAI values. The experimental results indicate that the Hyperion data are the most effective for mapping forest CC and LAI (CC mapped accuracy (MA) = 76.0%, LAI MA = 74.7%), followed by ALI data (CC MA = 74.5%, LAI MA = 70.7%), with ETM+ data results being least effective (CC MA = 71.1%, LAI MA = 63.4%). This analysis demonstrates that the Hyperion sensor outperforms the other two sensors: ALI and ETM+. This is because of its high spectral resolution with rich subtle spectral information, of its short-wave infrared data for constructing optimal VIs that are slightly affected by the atmosphere, and of its more available MNFs than the other two sensors to be selected for establishing prediction models. Compared to ETM+ data, ALI data are better for mapping forest CC and LAI due to ALI data with more bands and higher signal-to-noise ratios than those of ETM+ data.

    The oxidation addition of a series of σ H-X bonds (X = H, B, C, Si, N, P, and O) to a single Al(i) supported by a (NacNac)(-) bidentate ligand ((NacNac)(-) = [ArNC(Me)CHC(Me)NAr](-) and Ar = 2,6-(i)Pr2C6H3) has been explored through extensive DFT calculations. The presented results show that activation and addition of these σ bonds follow various reaction mechanisms, in which hydride transfer, proton transfer, and Al-X bond coupling steps are involved. The predicted free energy barriers for these oxidative additions range from 8 to 32 kcal mol(-1), and all the reactions are remarkably favorable thermodynamically. However, sterically hindered ligands, for most reactants, make the formation of the initial reactant complex difficult and may reduce the efficiency of the reaction. Calculations reveal a strong dependence of the reaction mechanism and low-energy channel on the bonding features of X-H and the local structural environments.

    Negative effects of noise on individuals, the inevitable result of urbanization, have become a significant urban problem in our day. Introduction of an approach to the noise problem on an urban-planning scale lightens the burden of measures required to be taken against noise at the stages of regional and developmental planning. Stadiums, which should be also evaluated from the point of noise problem when planning decisions are made on the urban planning scale, may cause very serious problems differing depending on the region they are located in. In this article, various dimensions of the noise problem caused by stadiums have been exemplified by making an assessment on Ali Sami Yen football stadium located in Mecidiyeköy district which is among important residential and commercial centres of İstanbul or Turkey. When the simulation results obtained for ordinary days and match days are evaluated, it has been found out that the people living in the area are exposed to noise levels substantially exceeding the acceptable values. Results of the survey conducted in the area have clearly revealed the existence of noise problem, too.

    The REF/ALY mRNA export adaptor binds TAP/NXF1 via an arginine-rich region, which overlaps with its RNA-binding domain. When TAP binds a REF:RNA complex, it triggers transfer of the RNA from REF to TAP. Here, we have examined the effects of arginine methylation on the activities of the REF protein in mRNA export. We have mapped the arginine methylation sites of REF using mass spectrometry and find that several arginines within the TAP and RNA binding domains are methylated in vivo. However, arginine methylation has no effect on the REF:TAP interaction. Instead, arginine methylation reduces the RNA-binding activity of REF in vitro and in vivo. The reduced RNA-binding activity of REF in its methylated state is essential for efficient displacement of RNA from REF by TAP in vivo. Therefore, arginine methylation fine-tunes the RNA-binding activity of REF such that the RNA-protein interaction can be readily disrupted by export factors further down the pathway.

The political situation of the district in this period is assessed in a way that comprises especially the period of Hz. Ali the fourth caliph of early islamic period Muaviya, the first Emevi caliph, and his son Yazid in the light of political developments in that period. When we took up Gulf of Basra we saw that the region of the Gulf is a very important strategic lacation. So since the most prohestoric period this area have got a lot of civilizations, big wars, social events and contentions. We saw that in the time of the region that we take up, the pozition of the Gulf area have gotten similar events in the past. Consequently, the area of the Gulf have owned most active pozition in that term that we take up. Especially because of the land trade roads, sea trade roads and riwer trade roads, Gulf of Basra have owned a very active junction at all time in the past and we easily guess that it will be protect its status in the future, too

    It is widely believed that the advance of science in the Islamic world after the mid-fifteenth century A.D. suffered a decline. For the purpose of examining this belief, a manuscript by Qasim ali al-Qayini (ca. A.D.1685) was chosen based on previous works which considered it a valuable source on the history of optics that had not been studied before. After studying his major optical manuscript, titled Manazir wa Maraya, it was found very interesting that the majority of al-Qayini's propositions relating to natural phenomena were not merely geometrical definitions, but that the proofs related to astronomy. As an example, in one case, which had not been explained in previous astronomical and optical manuscripts, al-Qayini tried, despite lacking a vigorous proof, to show how a special point in a room could be lit up by sunlight throughout the year. His particular interest in astronomy led us to a general study of his other works, and it is worth noting that out of the nineteen works that have been attributed to ...

  17. Stress conditions promote yeast Gap1 permease ubiquitylation and down-regulation via the arrestin-like Bul and Aly proteins.

    Gap1, the yeast general amino acid permease, is a convenient model for studying how the intracellular traffic of membrane transporters is regulated. Present at the plasma membrane under poor nitrogen supply conditions, it undergoes ubiquitylation, endocytosis, and degradation upon activation of the TORC1 kinase complex in response to an increase in internal amino acids. This down-regulation is stimulated by TORC1-dependent phosphoinhibition of the Npr1 kinase, resulting in activation by dephosphorylation of the arrestin-like Bul1 and Bul2 adaptors recruiting the Rsp5 ubiquitin ligase to Gap1. We report here that Gap1 is also down-regulated when cells are treated with the TORC1 inhibitor rapamycin or subjected to various stresses and that a lack of the Tco89 subunit of TORC1 causes constitutive Gap1 down-regulation. Both the Bul1 and Bul2 and the Aly1 and Aly2 arrestin-like adaptors of Rsp5 promote this down-regulation without undergoing dephosphorylation. Furthermore, they act via the C-terminal regions of Gap1 not involved in ubiquitylation in response to internal amino acids, whereas a Gap1 mutant altered in the N-terminal tail and resistant to ubiquitylation by internal amino acids is efficiently down-regulated under stress via the Bul and Aly adaptors. Although the Bul proteins mediate Gap1 ubiquitylation of two possible lysines, Lys-9 and Lys-16, the Aly proteins promote ubiquitylation of the Lys-16 residue only. This stress-induced pathway of Gap1 down-regulation targets other permeases as well, and it likely allows cells facing adverse conditions to retrieve amino acids from permease degradation.

    Detailed first-principle calculations of properties in zinc blende quaternary alloy BxAlyIn1-x-yN at various concentrations are investigated using density functional theory (DFT) within virtual crystal approximation (VCA) implemented in alchemical mixing approximation. The calculated bandgaps show direct transitions at Γ-Γ and indirect transitions at Γ-X, which are opened by increasing boron concentration. The density of state (DOS) revealed upper valence band (VB1) domination by p-states atoms, while s-states dominate the lower valence band (VB2); also, the DOS shows the contribution of d-states to the conduction band. The first critical point in the dielectric constant ranges between 0.07-4.47 eV and is due to the first threshold optical transitions in the energy bandgap. Calculated static dielectric function (DF) 𝜖1(0) is between 5.15 and 10.35, an indication that small energy bandgaps yield large static DFs. The present results indicate ZB-BxAlyIn1-x-yN alloys are suitable candidates of deep ultraviolet light emitting diodes (LEDs), laser diodes (LDs) and modern solar cell since the concentrations x and y make the bandgap and lattice constant of ZB-BxAlyIn1-x-yN quaternary alloys tunable to desirable values.

This project aims to develop a graphical symbolic system which is relevant to Turkish social and cultural systems of understanding. In the study, stories were developed (generated by a Turkish Language and Literature academic taking the objectives of primary 1st year life science, Turkish, and mathematics curricula into account. Stories, which consist of a setting, characters, and plot were developed. The stories were presented to 5 teachers who teach to hearing impaired students in order to check the appropriateness of each. Those teachers’ views were taken into account about the positive/negative effects of stories in the learning and teaching activities. On the other hand, all stories were elaborated by teachers in terms of whether they met the objectives of curriculum and were useful in developing the literacy skills of hearing impaired pupils. Teachers were asked to do any alterations or corrections needed to make stories compatible with curriculum objectives. Obtained data were analyzed descriptively. All participants stated that each of the stories were beneficial and usable for teaching and learning activities. They emphasized that sentences should be short, clear, and comprehendible and found that stories which were too long should be corrected. On the basis of teachers’ feed-back, 39 stories were re-designed and corrected. 8 stories which were found to be unsuitable were excluded from the study

    Background: Patients undergoing open heart surgery have a relatively high risk of acquiring nosocomial infections. The development of antibiotic-resistant infections is associated with prolonged hospital stays and mortalities. Objectives: The present study was conducted to investigate nosocomial infections and the antibiotic resistance pattern in bacteria causing these infections in open heart surgery patients at Imam Ali Hospital in Kermanshah in the west of Iran over a 4-year period from March 2011 to March 2014. Materials and methods: The present cross-sectional study was conducted on 135 cases of nosocomial infection among open heart surgery patients. The demographic characteristics and the risk factors of each case of infection were recorded. The antibiotic susceptibility test was carried out using the Minimum Inhibitory Concentration (MIC) method based on the Clinical and Laboratory Standards Institute (CLSI) protocol. The data collected were then analyzed in SPSS-16. Results: Out of the 6,000 patients who underwent open heart surgery during this 4-year period at the selected hospital, nosocomial infections developed in 135 patients (2.25%), 59.3% of whom were female and 40.7% male. Surgery site infection (SSI), pneumonia (PNEU), urinary tract infection (UTI) and blood stream infection (BSI) affected 52.6%, 37%, 9.6% and 0.8% of the cases, respectively. E.coli, Klebsiella spp. and S. aureus were the most common bacteria causing the nosocomial infections. E. coli was most frequently resistant to imipenem (23.3%) Klebsiella spp. to gentamicin (38.5%) S. aureus to co-trimoxazole (54.2%). Conclusion: SSI had a high prevalence in this study. Further studies should therefore be conducted to examine the risk factors associated with SSI in open heart surgery. Various studies have shown that antibiotic resistance patterns are different in different regions. Finding a definitive treatment therefore requires an antibiogram.

    Full Text Available Introduction : Patients with major thalassemia need recurrent transfusions and if not treated are at risk of heart dysfunction. Heart tissue could be abnormal in patients who use desferral continously due to iron deposits , fibrosis , hypertrophy and side effects of chronic anemia. Cardiac involvement is the main cause of morbidity and mortality in major thalassemics, so we decided to improve early diagnosis of cardiac involvement by measuring myocardial performance index( MPI . Method & Materials : This case-control study was performed from April 2003 to December 2003 at the Ali-Asghar pediatrics hospital, Zahedan, Iran. MPI of both ventricles was measured by Doppler echocardiography in 48 patients with major thalassemia aged between 10-18 years and compared with 48 age , sex-matched controls. Patients had no abnormality in physical examination , chest x-ray and ECG and echocardiography did not show heart failure. Hemoglobin and serum ferritin levels was measured in all patients before echocardiography. Results: Mean age of patients was 12.3±2.4 years and that in the control group was 12.7±2years . Right ventricle isovolumetric relaxation time (RVIRT (107 ± 14 vs 94 ±14 , p0.05 and LVICT (31 ± 13 vs 21 ± 15 , p0.05 in the two groups. Finally, RVMPI (0.59 ± 0.12 Vs 0.46 ± 0.12 , p<0.001 was increased in 87% of patients and LVMPI (0.49 ± 0.12 Vs 0.41± 0.09 , p0.05. Conclusion: This study showed that RVMPI and LVMPI increase in major thalassemia patients that indicates systolic and diastolic dysfunction and RVMPI increases more than LVMPI. On the other hand, MPI has a direct correlation with serum ferritin . On the basis of this study ,we suggest MPI measurement in serial echocardiography in asymptomatic major thalassemia patients.

    Transmigration of neutrophils (PMNs) from the vasculature into inflamed tissues, mediated by interactions between PMNs and adhesion molecules on endothelial cells, is an essential aspect of inflammation. The crucial adhesion molecules include junctional adhesion molecule (JAM)-A. Investigation of the role of this molecule in models of inflammatory disease has been limited, however, and results in different disease models have varied. No previous study has addressed JAM-A in lung disease or effects on oxidant stress and proinflammatory cytokines. We use JAM-A knockout mice and blocking antibodies to investigate the role of JAM-A in a murine model of acute lung injury (ALI). With either experimental system, we find that absence of JAM-A activity significantly reduces migration of PMNs into the alveolar space, with a resulting decrease in oxidative stress. However, there is no reduction in whole lung activity of PMN-associated myeloperoxidase, presumably reflecting the histologically observed retention of PMNs in lung tissue. Activity of these retained PMNs may account for our failure to find significant change in markers of lung oxidative stress or cytokine and chemokine levels in plasma, lung, and bronchoalveolar lavage fluid. We likewise see no JAM-A-related changes in markers of capillary permeability or lung injury. A similar lack of congruence between effects on PMN migration and tissue injury has been reported in other disease models and for other adhesion molecules in models of ALI. Our results thus confirm the crucial role of JAM-A in PMN transmigration but demonstrate that transmigration is not essential for other aspects of inflammation or for lung injury in ALI.

    Calcium and barium zirconate powders based upon CaZrO3:Eu3+, A and BaZrO3:Eu3+, A (A=Li+, Na+, K+) were prepared by combustion synthesis method and heating to ~1000 °C to improve crystal inity. The structure and morphology of materials were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD results showed that CaZrO3:Eu3 +, A and BaZrO3:Eu3 +, A (A=Li +, Na +, K +) perovskites possessed orthorhombic and cubic structures, respectively. The morphologies of al powders were very similar consisting of smal , coagulated, cubical particles with narrow size distributions and smooth and regular surfaces. The characteristic luminescences of Eu3+ ions in CaZrO3:Eu3+, A (A=Li+, Na+, K+) lattices were present with strong emissions at 614 and 625 nm for 5D0→7F2 transitions with other weaker emissions observed at 575, 592, 655, and 701 nm corresponding to 5D0→7Fn transitions (where n=0, 1, 3, 4, respectively). In BaZrO3:Eu3 + both the 5D0→7F1 and 5D0→7F2 transitions at 595 and 613 nm were strong. Photoluminescence intensities of CaZrO3:Eu3+ samples were higher than those of BaZrO3:Eu3+ lattices. This remarkable increase of photoluminescence intensity (corresponding to 5D0→7Fn transitions) was observed in CaZrO3:Eu3 + and BaZrO3:Eu3 + if co-doped with Li + ions. An additional broad band composed of many peaks between 440 to 575 nm was observed in BaZrO3:Eu3 +, A samples. The intensity of this band was greatest in Li+ co-doped samples and lowest for K+ doped samples.

    The Earth Observing-1 (EO-1) satellite was launched on November 21, 2000, as part of a one-year technology demonstration mission. The mission was extended because of the value it continued to add to the scientific community. EO-1 has now been operational for more than a decade, providing both multispectral and hyperspectral measurements. As part of the EO-1 mission, the Advanced Land Imager (ALI) sensor demonstrates a potential technological direction for the next generation of Landsat sensors. To evaluate the ALI sensor capabilities as a precursor to the Operational Land Imager (OLI) onboard the Landsat Data Continuity Mission (LDCM, or Landsat 8 after launch), its measured top-of-atmosphere (TOA) reflectances were compared to the well-calibrated Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) and the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) sensors in the reflective solar bands (RSB). These three satellites operate in a near-polar, sun-synchronous orbit 705 km above the Earth's surface. EO-1 was designed to fly one minute behind L7 and approximately 30 minutes in front of Terra. In this configuration, all the three sensors can view near-identical ground targets with similar atmospheric, solar, and viewing conditions. However, because of the differences in the relative spectral response (RSR), the measured physical quantities can be significantly different while observing the same target. The cross-calibration of ALI with ETM+ and MODIS was performed using near-simultaneous surface observations based on image statistics from areas observed by these sensors over four desert sites (Libya 4, Mauritania 2, Arabia 1, and Sudan 1). The differences in the measured TOA reflectances due to RSR mismatches were compensated by using a spectral band adjustment factor (SBAF), which takes into account the spectral profile of the target and the RSR of each sensor. For this study, the spectral profile of the target comes from the near-simultaneous EO-1

    Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. These concepts are discussed.

  14. Technical feasibility of a seabed gallery seawater intake at Ras Abu Ali Island, Arabian Gulf, Saudi Arabia

    Open-ocean intake systems require extensive and advanced pretreatment unit operation to produce feed water with low membrane fouling potential in seawater reverse osmosis (SWRO) facilities. Alternatively, subsurface intake systems tend to produce high quality raw seawater even before pretreatment. Subsurface intakes extract seawater indirectly through the geological structure of shoreline or nearshore sediments. Water percolation through geological units provides physical and biological treatment, so that the raw seawater is microbiologically stable with relatively low particulate and organics content. Overall, utilization of subsurface intakes will reduce the intensity of pretreatment, which reduces operating cost, lowers chemical and energy consumption, and reduces environmental impacts. An important aspect in the feasibility of a subsurface intake is the compatibility of the local geological environment. In this study, a field investigation was conducted at Ras Abu Ali Island in the Arabian Gulf. This location currently contains an of existing oil company facilities and a proposed governmental marine fish hatchery facility. Recreational, commercial, and domestic potable water uses require the need to use the SWRO process to meet demands. Characterization of the shoreline and marine offshore bottom were performed as well as observation of tidal fluctuations and wave heights. A specific grid area was chosen where 35 sediment samples were collected from the seabed floor for laboratory analysis of grain size distribution, sediment porosity, and hydraulic conductivity. Onsite observation showed that the marine bottom has a low slope creating a wide intertidal area. The lowest tidal zone is more than 150 m from the shoreline defining a far seaward boundary for the intake construction point. A relatively thin layer of mixed-type sediment (carbonate and siliciclastic) covers the marine hardground bottom. The unlithified bottom sediment contains a low mud percentage

    The Kabutar Ali Chai watershed is located in NW Iran, 75 km northwest of Tabriz, on the southern hillsides of Mishow mountains. It occupies an area of 67.46 km2 and the length of the main stream is about 24.5 km. Due to the fact that flooding in this watershed threats the downstream rural areas, an investigation was carried out to extract its geomorphologic characteristics and evaluate their contribution in flood production. In this regard, the watershed area was divided into 4 sections based on physiographic and topographic characteristics and stream network: A1 (the southern, low-height part), A2 (mid-western half), A3 (mid-eastern half) and A4 (the northern and highest part). Hypsometric maps and diagrams prepared for the area show that it is confined between 1390 and 3230m elevation levels with a general dip towards the south. The main part of it (57.93%) is located between the elevation levels of 1390 and 1500m. Using the precipitation records of 4 neighboring stations for 20 years, the estimated time of concentration for the runoff varies in the sub-zones: 1.64 hr in A1 (13.9 km stream length and 710 m altitude difference), 0.63 hr in A2 (7.2 km and 1200 m), 0.35 hr in A3 (4.7 km and 1530 m) and 0.48 hr in A4 (5.9 km and 1330 m.) Dip angle is one of the most important factors affecting the time of concentration for runoff and flood production. The average dip of the main part of the area (79.82%) ranges between 0 and 5°, while only the 0.44% of the area has dips about 30-40°. Highest dips are found in the A4 zone (0-40°) and the weight average dip of the total area is 12.94%. Geologically, the most widespread rocks are Pre-Cambrian shales, schists and limestones (Kahar Formation, 43.53%), upper-Cretaceous flysch sequence comprised of shale, limestone and sandstone (13.99%), Miocene marls, silts, clays and limestones (4.13%) and Quaternary alluvial terraces and plains (30.33%). Geomorphologically, this watershed is comprised of 3 types of lands: (1

    Chip-Multiprocessors are going to support massive parallelism by many additional physical and logical cores. Improving performance can no longer be obtained by increasing clock-frequency because the technical limits are almost reached. Instead, parallel execution must be used to gain performance.

    Full Text Available The state of the art for cell-based in vitro investigations of airborne and inhalable material is “air-liquid interface” (ALI technology. Cell lines, primary cells, complex 3D models, or precision-cut lung slices (PCLS are used to represent the lung or skin by way of an in vitro barrier model. These models have been applied in toxicity or pharmacological testing. However, contrasting with a clear demand for alternative methods, there is still no widely accepted procedure for cell-based in vitro testing of inhalable substances. In the light of this, an analysis was undertaken of common drawbacks of current approaches. Hence, the pivotal improvements aimed at were the cellular exposure environment, overall performance and applicability, operability of online investigations during exposure and routine setup. It resulted in an improved device (P.R.I.T. ExpoCube based on an “all-in-one-plate” concept including all phases of the experiment (cell culture, exposure, and read-out and all experimental groups (two test gas groups, controls in one single commercial multiwell plate. Verification of the concept was demonstrated in a first experimental series using reference substances (formaldehyde, ozone, and clean air. The resulting ALI procedure enables the application of inhalable substances and mixtures under highly effective exposure conditions in routine utilization.

    A potent and selective Factor IXa (FIXa) inhibitor was subjected to a series of liver microsomal incubations, which generated a number of metabolites. Using automated ligand identification system-affinity selection (ALIS-AS) methodology, metabolites in the incubation mixture were prioritized by their binding affinities to the FIXa protein. Microgram quantities of the metabolites of interest were then isolated through microisolation analytical capabilities, and structurally characterized using MicroCryoProbe heteronuclear 2D NMR techniques. The isolated metabolites recovered from the NMR experiments were then submitted directly to an in vitro FIXa enzymatic assay. The order of the metabolites' binding affinity to the Factor IXa protein from the ALIS assay was completely consistent with the enzymatic assay results. This work showcases an innovative and efficient approach to uncover structure-activity relationships (SARs) and guide drug design via microisolation-structural characterization and ALIS capabilities.

    Herpes simplex virus 1 (HSV-1) protein ICP27 has been shown to shuttle between the nucleus and cytoplasm and to bind viral RNA during infection. ICP27 was found to interact with the cellular RNA export adaptor protein Aly/REF, which is part of the TREX complex, and to relocalize Aly/REF to viral replication sites. ICP27 is exported to the cytoplasm through the export receptor TAP/NXF1, and ICP27 must be able to interact with TAP/NXF1 for efficient export of HSV-1 early and late transcripts. We examined the dynamics of ICP27 movement and its localization with respect to Aly/REF and TAP/NXF1 in living cells during viral infection. Recombinant viruses with a yellow fluorescent protein (YFP) tag on the N or C terminus of ICP27 were constructed. While the N-terminally tagged ICP27 virus behaved like wild-type HSV-1, the C-terminally tagged virus was defective in viral replication and gene expression, and ICP27 was confined to the nucleus, suggesting that the C-terminal YFP tag interfered with ICP27's C-terminal interactions, including the interaction with TAP/NXF1. To assess the role of Aly/REF and TAP/NXF1 in viral RNA export, these factors were knocked down using small interfering RNA. Knockdown of Aly/REF had little effect on the export of ICP27 or poly(A)(+) RNA during infection. In contrast, a decrease in TAP/NXF1 levels severely impaired export of ICP27 and poly(A)(+) RNA. We conclude that TAP/NXF1 is essential for ICP27-mediated export of RNA during HSV-1 infection, whereas Aly/REF may be dispensable.

  3. Geochemistry of rare earth elements in the Baba Ali magnetite skarn deposit, western Iran – a key to determine conditions of mineralisation

    2016-03-01

    Full Text Available The Baba Ali skarn deposit, situated 39 km to the northwest of Hamadan (Iran, is the result of a syenitic pluton that intruded and metamorphosed the diorite host rock. Rare earth element (REE values in the quartz syenite and diorite range between 35.4 and 560 ppm. Although the distribution pattern of REEs is more and less flat and smooth, light REEs (LREEs in general show higher concentrations than heavy REEs (HREEs in different lithounits. The skarn zone reveals the highest REE-enriched pattern, while the ore zone shows the maximum depletion pattern. A comparison of the concentration variations of LREEs (La–Nd, middle REEs (MREEs; Sm–Ho and HREEs (Er–Lu of the ore zone samples to the other zones elucidates two important points for the distribution of REEs: 1 the distribution patterns of LREEs and MREEs show a distinct depletion in the ore zone while representing a great enrichment in the skarn facies neighbouring the ore body border and decreasing towards the altered diorite host rock; 2 HREEs show the same pattern, but in the exoskarn do not reveal any distinct increase as observed for LREEs and MREEs. The ratio of La/Y in the Baba Ali skarn ranges from 0.37 to 2.89. The ore zone has the highest La/Y ratio. In this regard the skarn zones exhibit two distinctive portions: 1 one that has La/Y >1 beingadjacent to the ore body and; 2 another one with La/Y < 1 neighbouring altered diorite. Accordingly, the Baba Ali profile, from the quartz syenite to the middle part of the exoskarn, demonstrates chiefly alkaline conditions of formation, with a gradual change to acidic towards the altered diorite host rocks. Utilising three parameters, Ce/Ce*, Eu/Eu* and (Pr/Ybn, in different minerals implies that the hydrothermal fluids responsible for epidote and garnet were mostly of magmatic origin and for magnetite, actinolite and phlogopite these were of magmatic origin with low REE concentration or meteoric water involved.

    Full Text Available Mehmed Ali Pasha was the absolute ruler in Egypt since the Ottoman Empire was in very bad situation at that time as a result of some events. Mehmed Ali Pasha was among the soldiers sent to Egypt upon the invasion of the country by Napoleon. When his help was demanded to eliminate the rebellion in the Morea by the Sultan Mahmud the second of the Ottoman Empire, he wanted to be the governor of theMorea and the Crete Island in return for its help. However, when the Morea was taken by independent Greece in Edirne Treaty, therefore, he wanted to be the governor of Syria in place of the Morea. Sultan Mahmut the Second accepted to appoint him as the governor of the Crete Island but not Syria. As a result of this disagrement, he rebelled against the rule of The Ottoman Empire. His son, IbrahimPasha, invaded Syria with his Egyptian troops and he defeated the Ottoman army in Adana and Konya. He reached as far as Kutahya Province. The capital city, Istanbul,was in jeopardy and Sultan Mahmut the second, had to demand the aidof the Russians.When the Russian Navy reached Istanbul, England and France became worried about the situation. The domestic problem turned into an international one.The problem was solved temporarily by Kutahya Treaty signed by related states.In our study, issues related to the event such as the critical situations at that time, the worries of the people of the provinces, the technical and military support given to the empire by the provinces during Ibrahim Pasha's attacks, son of Mehmed Ali Pasha were discussed in the light of some documents and data emerged lately.The aim of the study is to introduce and discuss the event with a different aspect. Therefore, the studies about the subject done so far and documents in the archives of the empire were used. Screening model, one of the qualitative research was used in the study.

    Full Text Available Zn-Pb-Fe ores in the Ali ou Daoud deposit (Central High Atlas are found as stratiform levels and as karst fillings in carbonate platforms facies of Bajocian age. Tectonic structures (e.g., synsedimentary faults played a relevant role in the ore emplacement. The dolomitic ore-related host-rock levels are characterized by the presence of kaolinite enrichment in clay levels in amounts directly related to the proportion of the clay minerals. The latter is evidenced by correlation between kaolinite and sulphide contents, suggesting that the installation of kaolinite and mineralisations would result from the same hydrothermal fluid.[Français] Dans les séries sédimentaires carbonatées d’Ali ou Daoud (Haut Atlas Central, les minéralisations à Zn, Pb et Fe en amas stratiformes forment les faciès de remplissage des karsts d’une plateforme carbonatée bajocienne.

Dans les niveaux dolomitiques encaissants des minéralisations, les assemblages argileux sont caractérisés par la présence de kaolinite dont la teneur varie parallèlement avec celle du minerai.

    Recent studies have demonstrated that antiferromagnetic (AFM) semiconductors are promising alternative materials for spintronic applications. In this work, we report a detailed investigation of the magnetic and electronic properties of AMnAs (A=Li, Na, K, Rb, Cs) using density functional theory. It is found that all studied compounds are ordered antiferromagnetically in the MnAs ab plane, however, along the c axis, NaMnAs is ordered ferromagnetically which is different from the AFM coupling of other materials. These results on magnetic structures are in good agreement with observed facts. Furthermore, our calculations predict that all materials have a semiconducting band structure, which indicates the potential of device applications.

    Full Text Available Background: As There is not accurate information about ocular defects in Thalassemia Major (TM patients in Mazandaran province ,this study was designed to assess the prevalence of ophtalmopathies in thalassemic patients and also recognize its relevant factors in Sari Boo Ali Sina hospital. Sari. Materials and Methods: This descriptive Cross-sectional was Carried out on 60 TM patients in Thalassemia center at Sari Boo Ali Sina hospital. Subjects were selected by systematic sampling. After gathering demographic data , patients were evaluated about their illness and its complications from their medical records. Their visual acuity was assessed using Snell chart by an optometrist. Evaluation of retina was done by our ophthalmologist colleague. Visual evoked potential (VEP was assessed by TOENEES instrument made in Italy which had the ability to assess both VEP and P300 . Findings were analyzed by SPSS13 software and Chi square and Mann-whitney tests. Results: 60 patients underwen this study that 33 of them (55% were male. 4 of them (6.6% had problems in visual acuity . 3 of these became normal after refractive correction. 3 patients (5% had Inferior Posterior Cortical Cataract. 2 of them (3.3% had punctuate lens cortical opacity and one (1.7% had mild nuclear sclerosis. 4 patients( 6.7% had macular pigmentation and one (1.7% had left optic nerve head pit. No abnormal finding was detected in VEP, such as latency in voltage. Conclusion: Totally 20 patients had ocular complications. These defects can be a result of desferal toxicity or Iron toxicity and drug effects on binding to cupper and zinc and removing them from retinal cells or extramedulary hematopoesis. So based on the results, ophthalmologic evaluation of TM patients and tight desferal dose adjustment in these patients seems necessary.

Improving performance can no longer be obtained by increasing clock-frequency because the technical limits are almost reached. Instead, parallel execution must be used to gain performance. Resources like main memory, the cache hierarchy, bandwidth of the memory bus or links between cores and sockets are not going to be improved as fast.

Besides concurrent programming has become a domain for experts. Implementing multi-threading is error prone and labor-intensive. A full reimplementation of the whole AliRoot source-code is unaffordable. This paper describes the effort to evaluate the adaption of AliRoot to the needs of multi-threading and to provide the capability of parallel processing by using a semi-automatic source-to-source transformation to address the problems as described before and to provide a straight-forward way of parallelization with almost no interference between threads. This makes the approach simple and reduces the required manual changes in the code. In a first step, unconditional thread-safety will be introduced to bring the original sequential and thread unaware source-code into the position of utilizing multi-threading. Afterwards further investigations have to be performed to point out candidates of classes that are useful to share amongst threads. Then in a second step, the transformation has to change the code to share these classes and finally to verify if there are anymore invalid interferences between threads.

Tectonic structures (e.g., syn sedimentary faults) played a relevant role in the ore emplacement. The dolomitic ore-related host-rock levels are characterized by the presence of kaolinite enrichment in clay levels in amounts directly related to the proportion of the clay minerals. The latter is evidenced by correlation between kaolinite and sulphide contents, suggesting that the installation of kaolinite and mineralizations would result from the same hydrothermal fluid.

    Brownmillerite-type oxides Ba2In2−x−yMnxAlyO5+x (0≤x≤ 0.6, 0≤y≤ 0.5) were prepared at 1300°C through solid-state reaction. X-ray diffraction (XRD) analysis showed that the structure symmetry evolved from orthorhombic to cubic with increasing Mn and Al con-tents. Wheny was greater than 0.3, peaks associated with small amounts of BaAl2O4 and Ba2InAlO5 impurities were observed in the XRD patterns. When substituted with a small amount of Mn (x≤ 0.3), the Ba2In2−x−yMnxAlyO5+x samples exhibited an intense turquoise color. The color changed to green and dark-green with increasing Mn concentration. UV–vis absorbance spectra revealed that the color changed only slightly upon Al doping. The valence state of Mn ions in Ba2In2−x−yMnxAlyO5+x was confirmed to be +5 on the basis of X-ray photoelectron spectroscopic analysis. According to this analysis, the intense turquoise color of the Ba2In2−x−yMnxAlyO5+x samples is rooted in the existence of Mn5+; thus, the introduction of Al does not affect the optical properties of the compounds.

    Alginate lyases are important tools for oligosaccharide preparation, medical treatment, and energy bioconversion. Numerous alginate lyases have been elucidated. However, relatively little is known about their substrate degradation patterns and product-yielding properties, which is a limit to wider enzymatic applications and further enzyme improvements. Herein, we report the characterization and module truncation of Aly5, the first alginate lyase obtained from the polysaccharide-degrading bacterium Flammeovirga. Aly5 is a 566-amino-acid protein and belongs to a novel branch of the polysaccharide lyase 7 (PL7) superfamily. The protein rAly5 is an endolytic enzyme of alginate and associated oligosaccharides. It prefers guluronate (G) to mannuronate (M). Its smallest substrate is an unsaturated pentasaccharide, and its minimum product is an unsaturated disaccharide. The final alginate digests contain unsaturated oligosaccharides that generally range from disaccharides to heptasaccharides, with the tetrasaccharide fraction constituting the highest mass concentration. The disaccharide products are identified as ΔG units. While interestingly, the tri- and tetrasaccharide fractions each contain higher proportions of ΔG to ΔM ends, the larger final products contain only ΔM ends, which constitute a novel oligosaccharide-yielding property of guluronate lyases. The deletion of the noncatalytic region of Aly5 does not alter its M/G preference but significantly decreases the enzymatic activity and enzyme stability. Notably, the truncated protein accumulates large final oligosaccharide products but yields fewer small final products than Aly5, which are codetermined by its M/G preference to and size enlargement of degradable oligosaccharides. This study provides novel enzymatic properties and catalytic mechanisms of a guluronate lyase for potential uses and improvements. PMID:26519393

    Full Text Available A major problem facing battery-powered electric vehicles is in their batteries: weight and charge capacity. Thus, a battery-powered electric vehicle only has a short driving range. To travel for a longer distance, the batteries are required to be recharged frequently. In this paper, we construct a model for a battery-powered electric vehicle, in which driving strategy is to be obtained such that the total travelling time between two locations is minimized. The problem is formulated as an optimization problem with switching times and speed as decision variables. This is an unconventional optimization problem. However, by using the control parametrization enhancing technique (CPET, it is shown that this unconventional optimization is equivalent to a conventional optimal parameter selection problem. Numerical examples are solved using the proposed method.

    Full Text Available Introduction The Shah Soltan Ali area is located 85 km southwest of Birjand in the South Khorasan province. This area is part of the Tertiary volcanic-plutonic rocks in the east of the Lut block. The Lut block is bounded to the east by the Nehbandan and associated faults, to the north by the Doruneh and related faults (Sabzevar zone, to the south by the Makran arc and Bazman volcanic complex and to the west by the Nayband Fault. The Lut block is the main metallogenic province in the east of Iran (Karimpour et al., 2012, that comprises of numerous porphyry Cu and Cu–Au deposits, low and high sulfidation epithermal Au deposits, iron oxide deposits, base-metal deposits and Cu–Pb–Zn vein-type deposits. The geology of Shah Soltan Ali area is dominated by volcanic rocks, comprised of andesite and basalt, which are intruded by subvolanic units such as monzonite porphyry, monzodiorite porphyry and diorite porphyry. Materials and methods 1. 170 thin sections of the rock samples as well as 25 polished and thin polished sections were prepared for petrography, alteration and mineralization. 2. Twenty five samples were analyzed for Cu, Pb, Zn, Sb, Mo and As elements by the Aqua regia method in the Zarazama laboratory in Tehran, Iran. 3. Nine samples were analyzed for trace elements [including rare earth elements (REEs]. As a result of these analyses, trace elements and REE were determined by inductively coupled plasma mass spectrometry (ICP-MS in the ACME Analytical Laboratories (Vancouver Ltd., Canada. 4.

    Magnetite-rich Cyprus type VMS deposit has been recently discovered from the Ortaklar-Gaziantep region within Koçali complex, SE Turkey. Magnetite rich sulfide ore bodies are in close contact with underlying footwall spilitic basalts. These basalts are part of Koçali mélange, which represents an accreted oceanic complex during closing of southern Neotethys. These extrusives are low-K, low alkali tholeiites with Ca rich, partially sericitized plagioclase subophitically enclosed by augite with disseminated Fe-Ti oxides and pyrite. Mineral crystallization sequence of plagioclase followed by augite and opaque is typical of MORB. Major and trace element analyses for least altered basalts based on LOI (1.5~3.6 wt%), Ce/Ce* (0.9~1.1) exhibit limited range of element abundances. Low Mg# (59~60) suggests that basalts were derived from moderately evolved magma with fractional crystallization. HFSE (Th, Nb, Hf, Zr) were used for tectonic discrimination and basalts were plotted within MORB end spectrum, near MORB-IAT boundary. N-MORB normalized La to Lu ranges from 0.4 to 0.9 times N-MORB with LREE depletion [(La/Sm)N = 0.58~0.67] and flat HREE [(Tb/Lu)N = 0.95~1.05]. Chondrite normalized REE patterns resemble those of N-MORB but characterized by severe LREE depletion [(La/Sm)CN = 0.35~0.45]. LREE depletion coupled with high Sm/Nd (0.36~0.43), high CaO/Na2O (5.0~6.2) and low Nb/Yb (0.23~0.39) suggest depleted N-MORB composition derived from the refractory mantle source. Analyzed basalts are similar to those found from other rift (Costa Rica Rift Hole 504b) and intra-transform fault (Siqueiros transform). Magnetite emplacement occurring close to the ore-host boundary and lack of pyrrhotite from hosting basalts imply an involvement of oxidized hydrothermal fluids. Basalts probably have formed by late stage, partial melting of the refractory mantle at low pressure, shallow depth, and H2O rich environment. Possible source of mantle heterogeneity can be identified by isotope

    Next Generation Electric Propulsion (NGEP) technology development tasks are working towards advancing solar-powered electric propulsion systems and components to levels ready for transition to flight systems. Current tasks within NGEP include NASA's Evolutionary Xenon Thruster (NEXT), Carbon Based Ion Optics (CBIO), NSTAR Extended Life Test (ELT) and low-power Hall Effect thrusters. The growing number of solar electric propulsion options provides reduced cost and flexibility to capture a wide range of Solar System exploration missions. Benefits of electric propulsion systems over state-of-the-art chemical systems include increased launch windows, which reduce mission risk; increased deliverable payload mass for more science; and a reduction in launch vehicle size-- all of which increase the opportunities for New Frontiers and Discovery class missions. The Dawn Discovery mission makes use of electric propulsion for sequential rendezvous with two large asteroids (Vesta then Ceres), something not possible using chemical propulsion. NEXT components and thruster system under development have NSTAR heritage with significant increases in maximum power and Isp along with deep throttling capability to accommodate changes in input power over the mission trajectory. NEXT will produce engineering model system components that will be validated (through qualification-level and integrated system testing) and ready for transition to flight system development. NEXT offers Discovery, New Frontiers, Mars Exploration and outer-planet missions a larger deliverable payload mass and a smaller launch vehicle size. CBIO addresses the need to further extend ion thruster lifetime by using low erosion carbon-based materials. Testing of 30-cm Carbon-Carbon and Pyrolytic graphite grids using a lab model NSTAR thruster are complete. In addition, JPL completed a 1000 hr. life test on 30-cm Carbon-Carbon grids. The NSTAR ELT was a life time qualification test started in 1999 with a goal of 88 kg

    A controversial proposal to deregulate a major part of the electric utility industry could transform how electric power is produced. The proposal involves one-third of US energy consumption and violates the classic economic theory that tightly regulated natural monopolies serve society's needs best. Supporters of the proposal suggest that free-market competition may now be valid because new technologies and new power-supply sources can introduce innovation and efficiency into cost control. Many states, for example, allow utilities to pass capital costs through to their users. Alternative energy sources could include small hydro, wind power, and industrial cogeneration. Opponents, who question whether there really is a free market in energy production, suggest better regulation to protect consumers. Some of the opposition will come from utilities wanting to keep their captive markets. (DCK)

    Cutaneous leishmaniasis (CL) is still considered as a health problem in the world. Several methods of control in different regions, together with obtaining integrated information on its natural foci, are needed to decrease its prevalence. This study was designed to evaluate the effects of simultaneous interventions on CL control. A standard questionnaire was used to identify patients among pilgrims to Emamzadeh Agha Ali Abbas (Isfahan Province, Iran). Subsequently, three methods of controlling the disease, including, spraying residential buildings with Baygon, baiting with zinc phosphide poisons, changing the vegetative cover of the region, improving the environment, and mounting a mesh on all doors and windows of buildings in residential areas were used. The control measures were then evaluated by comparing the number of pilgrims affected by CL after and before the interventions. While 23 pilgrims (1.4%) were affected with CL before the intervention (pretest), five (0.3%) persons were found to have CL after taking control measures. The Chi-square test did not indicate any significant difference in the relative frequency of CL (P = 0.731). The only scientific method for preventing and controlling zoonotic CL (ZCL) is a combination of the control methods (improving the environment and fighting off the disease districts and vectors) together with changing the vegetative cover of the region. Any measure for controlling this disease must be taken and programmed in accordance with the relevant experts' views, in coordination with the participation of other organizations and the society.

    Messenger RNA (mRNA) export adaptors play an important role in the transport of mRNA from the nucleus to the cytoplasm. They couple early mRNA processing events such as 5' capping and 3' end formation with loading of the TAP/NXF1 export receptor onto mRNA. The canonical adaptor REF/ALY/Yra1 is recruited to mRNA via UAP56 and subsequently delivers the mRNA to NXF1 [1]. Knockdown of UAP56 [2, 3] and NXF1 [4-7] in higher eukaryotes efficiently blocks mRNA export, whereas knockdown of REF only causes a modest reduction, suggesting the existence of additional adaptors [8-10]. Here we identify a new UAP56-interacting factor, UIF, which functions as an export adaptor, binding NXF1 and delivering mRNA to the nuclear pore. REF and UIF are simultaneously found on the same mRNA molecules, and both proteins are required for efficient export of mRNA. We show that the histone chaperone FACT specifically binds UIF, but not REF, via the SSRP1 subunit, and this interaction is required for recruitment of UIF to mRNA. Together the results indicate that REF and UIF represent key human adaptors for the export of cellular mRNAs via the UAP56-NXF1 pathway.

    Magnetic excitations and their role for the superconductivity in cuprate superconductors have been widely discussed in the literature. Here, we present a study of Y1-x Prx Ba2Cu3-yAlyO7-δ single crystals using Raman spectroscopy in an energy range of 50 10000 cm-1 Raman shift. The high energy range is dominated by a two-magnon scattering process at 3J, where J is the superexchange energy. In the Pr-123 single crystal, we find J = 720 cm-1, a damping of the one-magnon states Γ = 200 cm-1, and a resonance energy of 2.79eV for the two-magnon excitation. The two-magnon peak shows a continuous increase of the one-magnon damping with decreasing x and a nearly constant J across the phase transition to the superconductor. Especially, we find a weak two-magnon peak for a superconductor with a Tc = 86 K.

The nonahydrate of aluminium bromide, stable pentadecahydrates of aluminium chloride, bromide and iodide, and a metastable heptadecahydrate of the iodide have now been crystallized from low-temperature solutions. The structures of these hydrates were determined and are discussed in terms of the development of cation hydration spheres. The pentadecahydrate of the chloride and bromide are isostructural. In AlI(3) · 15H2O, half of the Al(3+) cations are surrounded by two complete hydration spheres, with six H2O in the primary and 12 in the secondary. For the heptadecahydrate of aluminium iodide, this hydration was found for every Al(3+).

    quantify both the presence and degree of structural disturbance caused by various logging regimes. Our quantitative assessment of Hyperion hyperspectral and ALI multi-spectral data for the detection and structural characterization of selective logging in Amazonia will benefit from data collected through an ongoing project run by the Tropical Forest Foundation, within which we have developed a study of the canopy and landscape biophysics of conventional and reduced-impact logging. We will add to our base of forest structural information in concert with an EO-1 overpass. Using a photon transport model inversion technique that accounts for non-linear mixing of the four biogeophysical indicators, we will estimate these parameters across a gradient of selective logging intensity provided by conventional and reduced impact logging sites. We will also compare our physical ly-based approach to both conventional (e.g., NDVI) and novel (e.g., SWIR-channel) vegetation indices as well as to linear mixture modeling methods. We will cross-compare these approaches using Hyperion and ALI imagers to determine the strengths and limitations of these two sensors for applications of forest biophysics. This effort will yield the first physical ly-based, quantitative analysis of the detection and intensity of selective logging in Amazonia, comparing hyperspectral and improved multi-spectral approaches as well as inverse modeling, linear mixture modeling, and vegetation index techniques.

    Full Text Available Objective: To describe the growth, reproductive biology and abundance of the population of invasive shrimps Palaemon elegans (P. elegans in one of the branches of Garmat Ali river at Basrah, Southern Iraq. Methods: Monthly samples of the prawn P. elegans were collected with a bottom hand net (40 cm, 0.5 mm mesh hauled over a distance of 10 m. A simple random sampling was conducted monthly between December 2012 and November 2013. Results: Seasonal changes were observed in the composition of the population of the species during the study year with the highest abundance in 2013 and the lowest abundance for the males was reported in January and for the females occurred in June. Salinity showed a significant correlation with the abundance of shrimps at the sampling site. The largest female measured 67.90 mm while the corresponding value for males was 61.31 mm. The proportion of ovigerous adults rose during spring season to peak on about July and ovigerous prawns were taken in all months of the year. The sex ratio indicated a preponderance of females over males in all months in the study period. Each females produced around 36–1324 eggs and the incubation period lasted for 11–14 days at 17–29 °C. Conclusions: The results of the present study indicate that this species has a wide distribution range, high density, and great reproduction potential. This study reveals the lack of researches on this species in environments of Shatt Al-Arab river and its branches. Thus, P. elegans has most likely formed a permanent population in all the brackish waters in Basrah area.

    Objective:To describe the growth, reproductive biology and abundance of the population of invasive shrimpsPalaemon elegans (P. elegans) in one of the branches of Garmat Ali river at Basrah, Southern Iraq. Methods:Monthly samples of the prawnP. elegans were collected with a bottom hand net (40 cm, 0.5 mm mesh) hauled over a distance of 10 m. A simple random sampling was conducted monthly between December 2012 and November 2013. Results:Seasonal changes were observed in the composition of the population of the species during the study year with the highest abundance in 2013 and the lowest abundance for the males was reported in January and for the females occurred in June. Salinity showed a significant correlation with the abundance of shrimps at the sampling site. The largest female measured 67.90 mm while the corresponding value for males was 61.31 mm. The proportion of ovigerous adults rose during spring season to peak on about July and ovigerous prawns were taken in all months of the year. The sex ratio indicated a preponderance of females over males in all months in the study period. Each females produced around 36–1 324 eggs and the incubation period lasted for 11–14 days at 17–29°C. Conclusions:The results of the present study indicate that this species has a wide distribution range, high density, and great reproduction potential. This study reveals the lack of researches on this species in environments of Shatt Al-Arab river and its branches. Thus,P. elegans has most likely formed a permanent population in all the brackish waters in Basrah area.

    Full Text Available Background and purpose: Chronic abdominal pain is a common clinical problem in children. Apleys reported the incidence of 10-15% of chronic abdominal pain in school age children, but recent studies reported 20% of that type of pain. The aim of this study was determining the spectrum of clinical manifestations of dyspeptic children and to identify the relation between some clinical symptoms, organic or functional dyspepsia, and long term follow up of functional type.Materials and Methods: This descriptive case series study was done on 232 children between 4 and 18 years of age complaining about chronic abdominal pain chiefly who had referred to pediatric gastroenterology department of Boo-Ali Hospital of sari in 2005-2006. A checklist composed of patient demographic criteria and pain characteristics was prepared. Physical exam and laboratory tests such as AST, ALT, U/A, U/C, S/E, ESR, CBC were performed for all patients. If there were any alarming signs of organic abdominal pain-persistence or recurrence of symptoms and severe disability despite the use of H-blockers-upper GI endoscopies was indicated. Recorded data were analyzed by SPSS software and Chi- square tests.Results: 102 of 232 patients had dyspepsia; 59 were girls (9.2y/o, and 43 were boys (7.5y/o. 65 out of 102 patients had dominant abdominal pain and the rest had flatulence, vomiting and early fullness. 64 of them went under UGI endoscopies. 28 of 64 had mucosal erosion.Conclusion: Because the functional or organic abdominal pain has not unique diagnostic criteria, and the data about pathological change in children are fewer than that of adults we recommend the clinical findings and biochemical change of mucosa for differential diagnosis in children.

    Acute lung injury (ALI) is an inflammatory disorder associated with reduced alveolar-capillary barrier function and increased pulmonary vascular permeability. Vasodilator-stimulated phosphoprotein (VASP) is widely associated with all types of modulations of cytoskeleton rearrangement-dependent cellular morphology and function, such as adhesion, shrinkage, and permeability. The present studies were conducted to investigate the effects and mechanisms by which tumor necrosis factor-alpha (TNF-α) increases the tight junction permeability in lung tissue associated with acute lung inflammation. After incubating A549 cells for 24 hours with different concentrations (0-100 ng/mL) of TNF-α, 0.1 to 8 ng/mL TNF-α exhibited no significant effect on cell viability compared with the 0 ng/mL TNF-α group (control group). However, 10 ng/mL and 100 ng/mL TNF-α dramatically inhibited the viability of A549 cells compared with the control group (*pTNF-α for 24 hours displayed significantly increased cell permeability (*pinhibition of VASP expression increased the cell permeability (*pTNF-α in lung tissues and serum significantly increased at one hour, and the value reached a peak at four hours. Moreover, the Evans Blue absorption value of the mouse lung tissues reached a peak at four hours. The HIF-1α protein expression level in mouse lung tissues increased significantly at four hours and eight hours (**pTNF-α to inhibit VASP expression and to modulate the acute pulmonary inflammation process, and these molecules play an important role in the impairment of the alveolar-capillary barrier.

    Full Text Available Oral polio vaccine has been used successfully as a powerful tool to control the spread of wild polioviruses throughout the world; however, during replication in under immunized children, some vaccine viruses revert and acquire the neurovirulent phenotypic properties. In this study, we describe the evolution and circulation of Vaccine-Derived Polioviruses (VDPVs in Helmand province of Afghanistan. We investigated 2646 AFP cases of Afghan children from June 2009-February 2011 and isolated 103 (04% vaccine viruses, 45(1.7% wild type polioviruses and six (0.22% type 2 circulating vaccine-derived polioviruses (cVDPVs. These cVDPVs showed 97.7%-98.2% nucleotide and 98%-98.7% amino acid homology in VP1 region on comparison with Sabin type 2 reference strain. All these cVDPVs had two signature mutations of neurovirulent phenotypes and 12 additional mutations in P1 capsid region that might also have contributed to increase neurovirulence and replication. Phylogenetic analysis revealed that all these viruses were closely related and originated from previously reported Sabin like 2 virus from Pakistan which did not conform to the standard definition of VDPVs at that time. It was also observed that initial OPV dose was administered approximately 9 months prior to the collection of first stool specimen of index case. Our findings support that suboptimal surveillance and low routine immunization coverage have contributed to the emergence and spread of these viruses in Afghanistan. We therefore recommend high quality immunization campaigns not only in affected district Nad Ali but also in the bordering areas between Pakistan and Afghanistan to prevent the spread of cVDPVs.

    One of the issues in health care delivery system is resistance to antibiotics. Many researches were done to show the causes and antibiotics which was resistance. In most researches the methods of classifying and reporting this resistance were made by researcher, so in this research we examined the International Classification of Diseases 10 the edition (ICD-10). This is a descriptive cross section study; data was collected from laboratory of Boo Ali Sina hospital, during 2011-2012. The check list was designed according the aim of study. Variables were age, bacterial agent, specimen, and antibiotics. The bacteria and resistance were classified with ICD-10. The data were analyzed with SPSS (16) soft ware and the descriptive statistics. Results showed that of the 10198 request for culture and antibiogram, there were 1020(10%) resistance. The specimen were 648 (63.5%) urine, blood 127(12.5%), other secretion 125 (12/3%), sputum 102 (10%), lumbar puncture 8 (0/8%), stool 6 (6/0%) and bone marrow 4 (0.4%). The E coli was the most 413 (40.5%) resistance cause to antibiotics which was coded with B96.2 and the most resistance was to multiple antibiotics 885(86.8%) with the U88 code. The results showed that by using the ICD-10 codes, the study of multiple causes and resistance is possible. The routine usage of coding of the ICD-10 would result to an up to date bank of resistance to antibiotics in every hospitals and useful for physicians, other health care, and health administrations.

  10. Development of Antisense Therapeutic and Imaging Agents to Detect and Suppress Inducible Nitric Oxide Synthase (iNOS) Expression in Acute Lung Injury (ALI)

    Shen, Yuefei

    This dissertation focuses on the development and investigation of antisense imaging and therapeutic agents, combined with nanotechnology, to detect and suppress inducible nitric oxide synthase (iNOS) expression for the diagnosis and treatment of acute lung injury (ALI). To achieve this goal, several efforts were made. The first effort was the identification and characterization of high binding affinity antisense peptide nucleic acids (PNAs) and shell-crosslinked knedel-like nanoparticle (SCK)-PNA conjugates to the iNOS mRNA. Antisense binding sites on the iNOS mRNA were first mapped by a procedure for rapidly generating a library of antisense accessible sites on native mRNAs (MASL) which involves reverse transcription of whole cell mRNA extracts with a random oligodeoxynucleotide primer followed by mRNA-specific PCR. Antisense PNAs against the antisense accessible sites were accordingly synthesized and characterized. The second effort was the investigation of cationic shell crosslinked knedel-like nanoparticle (cSCK)-mediated siRNA delivery to suppress iNOS expression for the treatment of ALI. siRNA with its unique gene-specific properties could serve as a promising therapeutic agent, however success in this area has been challenged by a lack of efficient biocompatible transfection agents. cSCK with its nanometer size and positive charge previously showed efficient cellular delivery of phosphorothioate ODNs (oligodeoxynucleotides), plasmid DNA and PNA. Herein, cSCK showed good siRNA binding and facilitated efficient siRNA transfection in HeLa, a mouse macrophage cell line and other human cell lines. cSCK led to greater silencing efficiency than Lipofectamine 2000 in HeLa cells as determined by the viability following transfection with cytotoxic and non-cytotoxic siRNAs, as well in 293T and HEK cells, and was comparable in BEAS-2B and MCF10a cells. The third effort was the preparation of an iNOS imaging probe through electrostatic complexation between a radiolabeled

    Tunable coherent deep ultraviolet (DUV) light sources, especially ultrashort pulse DUV lasers have great appli-cations in the fields of time-resolved, material processing, spectroscopy, laser spectroscopy and laser fusion. In the UV region, the best choice of generating the laser pulses in the femtosecond or picosecond regime is the frequency up-conversation technique based on second order nonlinearities. Over the past three decades, quite a lot of nonlinear crystals, such as LiB3O5, β-BaB2O4, KBe2BO3F2 and Ba1−xB2−y−zO4SixAlyGaz have been developed and employed for gener-ating the femtosecond pulses in the blue, ultraviolet, and even the deep-ultraviolet region. A tunable deep ultraviolet femtosecond laser is experimentally studied based on the new nonlinear crystal Ba1−xB2−y−zO4SixAlyGaz It is a kind of low-temperature phase barium metaborate single crystal belonging to a trigonal system, doped with one or more elements selected from Si, Al and Ga. As an optimized β-BaB2O4 crystal, Ba1−xB2−y−zO4SixAlyGaz completely overcomes the shortcomings of deliquescence compared withβ-BaB2O4, and its nonlinear efficiency and optical damage threshold have also been greatly improved. Using two crystals as second harmonic generation is to compensate for the spatial walk-off effect and the light path walk-off due to refraction effect The optical axis of the second Ba1−xB2−y−zO4SixAlyGaz is twice the phase matching angle with respect to the first one. In a femtosecond regime, short pulse provides high efficient frequency conversation due to their high peak powers, but the group velocity mismatch is a cognitive factor to limit conversion efficiency. It is obvious that after the frequency doubling, the second harmonic pulse and fundamental pulse separate from each other. The second harmonic pulse lags behind the fundamental pulse as they propagate through the crystal and the second harmonic pulse is broadened into a longer pulse duration than the

    Eurycoma longifolia Jack (known as tongkat ali), a popular traditional herbal medicine, is a flowering plant of the family Simaroubaceae, native to Indonesia, Malaysia, Vietnam and also Cambodia, Myanmar, Laos and Thailand. E. longifolia, is one of the well-known folk medicines for aphrodisiac effects as well as intermittent fever (malaria) in Asia. Decoctions of E. longifolia leaves are used for washing itches, while its fruits are used in curing dysentery. Its bark is mostly used as a vermifuge, while the taproots are used to treat high blood pressure, and the root bark is used for the treatment of diarrhea and fever. Mostly, the roots extract of E. longifolia are used as folk medicine for sexual dysfunction, aging, malaria, cancer, diabetes, anxiety, aches, constipation, exercise recovery, fever, increased energy, increased strength, leukemia, osteoporosis, stress, syphilis and glandular swelling. The roots are also used as an aphrodisiac, antibiotic, appetite stimulant and health supplement. The plant is reported to be rich in various classes of bioactive compounds such as quassinoids, canthin-6-one alkaloids, β-carboline alkaloids, triterpene tirucallane type, squalene derivatives and biphenyl neolignan, eurycolactone, laurycolactone, and eurycomalactone, and bioactive steroids. Among these phytoconstituents, quassinoids account for a major portion of the E. longifolia root phytochemicals. An acute toxicity study has found that the oral Lethal Dose 50 (LD50) of the alcoholic extract of E. longifolia in mice is between 1500-2000 mg/kg, while the oral LD50 of the aqueous extract form is more than 3000 mg/kg. Liver and renal function tests showed no adverse changes at normal daily dose and chronic use of E. longifolia. Based on established literature on health benefits of E. longifolia, it is important to focus attention on its more active constituents and the constituents' identification, determination, further development and most importantly, the

    The karstic lakes of the Middle Atlas, Morocco, represent a valuable archive of environmental and climatic change for Northwest Africa. Here we present the results of centennial-scale palynological and charcoal analyses as part of a multiproxy palaeolimnological study of sediment cores from Lake Sidi Ali in the Middle Atlas, Morocco (33° 03 N, 05° 00 W; 2,080 m a.s.l.). Supported by absolute dating including 23 more than twenty AMS 14C dates on pollen concentrates, the record covers the entire Holocene and offers insights into vegetation and climate change at a regionally unprecedented centennial-scale. Pollen assemblages are dominated by steppic herbs, evergreen oaks (Quercus), junipers (Cupressaceae) and Atlantic cedar (Cedrus atlantica). A long-term evolution of the montane vegetation is recorded, reflecting progressive changes in the dominant arboreal taxa and leading to the full establishment of the emblematic cedar forests of the area during the mid-Holocene by 6000 cal BP. Orbital-scale changes in seasonality and growing season moisture availability linked to declining summer insolation are implicated, with a transition from (a) warm, dry summers associated with summer drought tolerant taxa especially evergreen Quercus, high algal productivity in the lake, and high background levels of microcharcoal reflecting distant fire activity during the early Holocene, to (b) cool, relatively humid summers with dominance of montane conifers, declining algal productivity in the lake, and episodic local fire activity during the mid- to late Holocene. Superimposed on the long-term environmental changes are recurrent centennial-scale fluctuations in vegetation composition, reflecting competitive dynamics between the major taxa, initially between steppic and arboreal elements, and later between the major tree taxa. Parallels with hydrological proxies including stable O and C isotopes suggest common responses to climatic drivers (fluctuations in moisture sources and

    La diffusion des neutrons est une technique particulièrement efficace pour l'analyse en temps réel des processus réactionnels dans la matière. La diffraction de neutrons in situ a été développée très tôt sur les sources à haut flux tel que l'Institut Laue Langevin. Ces études nécessitent un flux de neutrons important et un détecteur couvrant un domaine angulaire le plus grand possible. Les neutrons offrent la spécificité d'être très peu absorbés par nombre de matériaux, cette faible absorption fait de la diffusion neutronique un excellent outil pour sonder la matière en volume et de manière non destructive. Cela permet en particulier d'utiliser des environnements d'échantillons complexes tout en conservant un flux raisonnable. La diffusion de neutrons en temps réel est donc très largement utilisée par diverses communautés scientifiques : sciences des matériaux, physiciens, chimistes... L'objet de ce cours est de donner les paramètres importants pour ce type d'étude et d'illustrer le propos à l'aide d'exemples pris dans des domaines scientifiques divers : électrochimie, magnétisme, métallurgie, chimie du solide. Après avoir présenté quelques repères méthodologiques sur les méthodes d'acquisition de données, des exemples montreront le fort potentiel de la diffusion neutronique en temps réel pour l'étude de la matière dans des conditions dynamiques. Enfin, nous donnerons aussi quelques conseils pour la visualisation, le dépouillement et l'analyse de ce type d'expérience. La diffusion des neutrons sur poudre est actuellement très bien adaptée aux études réalisées in situ. Cependant, nous verrons que la faisabilité d'études in situ s'étend à d'autres techniques expérimentales telles que la diffusion des neutrons aux petits angles et même la diffusion sur monocristal qui est en plein renouveau.

    Full Text Available This article aims to demonstrate a small group of intellectuals’ thoughts on nationalism and Turkish national identity who had tried to give an answer by searching for a new and unique Turkish humanism in general and particularly former Minister of Education, Hasan Ali Yücel’s period (1939-1946 and his humanist reformist approach to politics during the nation/identity-building process in the early decades of Republican Era. After the historical and social transition, French Revolution spreading the ideas of equality, liberty and fraternity giving rise to nationalist movements throughout Europe ended up with the decline of the multi-national empires and gave birth to the nation-states. Like the others, a new nation-state, Turkish Republic was established after the Ottoman Empire had collapsed. Turkish modernization initially took a form of westernization. Three ideologies; Pan-Ottomanism, Pan-Islamism and Pan-Turkism were seen as an appropriate direction for the society’s search for a new identity. At the same time, Turkish national identity was seen as an appropriate direction for the society’s search for a new identity and The republican elite embarked a radical stand and defined Turkish identiy as western modern secular nation which later became a dominant ideology for the new republic. At the time of early years of Republic, there were seen different acceptions for the content national identity. Hasan Ali Yücel and intellectuals searching for Turkish humanism defined modern Turkish identity by deriving it from Anatolian humanism, which could be realized through a Turkish Renaissance and claimed that it would be possible to create a unique Anatolian identity by this definition.

    A new detailed palaeomagnetic study of Tertiary volcanics, including extensive K-Ar and 40Ar/39Ar dating, helps constrain the deformation mechanisms related to the opening processes of the Afar depression (Ethiopia and Djibouti). Much of the Afar depression is bounded by 30 Myr old flood basalts and floored by the ca 2 Myr old Stratoid basalts, and evidence for pre-2 Ma deformation processes is accessible only on its borders. K-Ar and 40Ar/39Ar dating of several mineral phases from rhyolitic samples from the Ali Sabieh block shows indistinguishable ages around 20 Myr. These ages can be linked to separation of this block in relation to continental breakup. Different amounts of rotation are found to the north and south of the Holhol fault zone, which cuts across the northern part of the Ali Sabieh block. The southern domain did not record any rotation for the last 8 Myr, whereas the northern domain experienced approximately 12 +/- 9° of clockwise rotation. We propose to link this rotation to the counter-clockwise rotation observed in the Danakil block since 7 Ma. This provides new constraints on the early phases of rifting and opening of the southern Afar depression in connection with the propagation of the Aden ridge. A kinematic model of propagation and transfer of extension within southern Afar is proposed, with particular emphasis on the previously poorly-known period from 10 to 4 Ma.

    2011-01-01

    Full Text Available A la suite d’Esquirol dans son traité Des maladies mentales de 1838, ceux que l’on appelait alors les « aliénistes » proposent de nouvelles théories de l’imagination qui, considérées dans leur ensemble, esquissent un cadre épistémique que Flaubert utilise comme cadre rhétorique dans la troisième version de la Tentation de saint-Antoine. Toutefois, l’auteur n’accepte pas l’assimilation de l’état dans lequel se trouve l’artiste lorsqu’il crée à une hallucination pathologique. Il s’oppose en cela à la théorie de Moreau de Tours ; en revanche, il se montre plus proche de la pensée de Brierre de Boismont (et de celle de l’historien Alfred Maury. Par cet usage intelligemment mitigé du cadre épistémique de l’aliénisme contemporain et par l’invention d’une prose poétique dont les soubassements théoriques annoncent certaines conceptions de Freud et de Nietzsche, Flaubert dépasse résolument les esquiroliens.

    Vila, J.; Rilo, E.; Segade, L.; Cabeza, O.; Varela, L. M.

    2005-03-01

    We present experimental measurements of the specific electrical conductivity (σ) in aqueous solutions of aluminum salts at different temperatures, covering all salt concentrations from saturation to infinite dilution. The salts employed were AlCl3 , AlBr3 , AlI3 , and Al(NO3)3 , which present a 1:3 relationship between the electrical charges of anion and cation. In addition, we have measured the density in all ranges of concentrations of the four aqueous electrolyte solutions at 298.15K . The measured densities show an almost linear behavior with concentration, and we have fitted it to a second order polynomial with very high degree of approximation. The measurement of the specific conductivity at constant temperature reveals the existence of maxima in the conductivity vs concentration curves at molar concentrations around 1.5M for the three halide solutions studied, and at approximately 2M for the nitrate. We present a theoretical foundation for the existence of these maxima, based on the classical Debye-Hückel-Onsager hydrodynamic mean-field framework for electrical transport and its high concentration extensions, and also a brief consideration of ionic frictional coefficients using mode-coupling theory. We also found that the calculated values of the equivalent conductance vary in an approximately linear way with the square root of the concentration at concentrations as high as those where the maximum of σ appears. Finally, and for completeness, we have measured the temperature dependence of the electrical conductivity at selected concentrations from 283to353K , and performed a fit to an exponential equation of the Vogel-Fulcher-Tamman type. The values of the calculated temperatures of null mobility of the four salts are reported.

    The nuclear electric quadrupole moment (Q moment) of the neutron-rich nucleus {sup 33}Al(I=5/2,T{sub 1/2} =41 ms) has been measured by the {beta} -ray detected nuclear quadrupole resonance ({beta} -NQR) method for the first time. The {sup 33}Al nucleus is considered to be on the border of the island of inversion within which a significant intrusion of the pf orbits occurs across the N=20 shell gap and the intrusion causes an anomalous enhancement of the Q moment. Polarized {sup 33}Al nuclei were produced from {sup 36}S (77.5MeV/u) beams through the fragmentation process and separated by LISE fragment separator at GANIL. The {sup 33}Al nuclei were implanted into a Al{sub 2}O{sub 3} single-crystal plate and the {beta} -NQR spectrum was successfully obtained. (orig.)

    A novel green phosphor SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} is synthesized by a high temperature solid-state method, and its luminescent property is investigated. X-ray diffraction patterns of SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} indicate a similarity crystalline phase to SrZn{sub 2}(PO{sub 4}){sub 2}. SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} shows green emission under 369 nm excitation, and the prominent luminescence in green (544 nm) due to {sup 5}D{sub 4}–{sup 7}F{sub 5} transition of Tb{sup 3+}. For the 544 nm emission, excitation spectrum has several excitation band from 200 nm to 400 nm. Emission intensity of SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} is influenced by Tb{sup 3+} concentration, and concentration quenching effect of Tb{sup 3+} in SrZn{sub 2}(PO{sub 4}){sub 2} is also observed. With incorporating A{sup +} (A=Li, Na, and K) as compensator charge, the emission intensity of SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} can be obviously enhanced. CIE color coordinates of SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} locate in the green region. The results indicate this phosphor may be a potential application in white LEDs. - Graphical abstract: SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} can produce green emission under near-UV excitation, and its luminescent properties can be improved by incorporating A{sup +} (A=Li, Na, and K). - Highlights: • SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} can produce green emission under near-UV excitation. • Concentration quenching effect of Tb{sup 3+} in SrZn{sub 2}(PO{sub 4}){sub 2} is observed. • Emission intensities of SrZn{sub 2}(PO{sub 4}){sub 2}:Tb{sup 3+} are enhanced by codoped A{sup +} (A=Li, Na, K)

It would take enormous ingenuity to find substitutes. If all electricity were shut off, then all electronic devices would be dead. Electric lights would darken. Aluminum would become a rare metal. All factories would have to develop power sources on the spot and would have to switch to primitive, mechanical controls.

  17. Application of multivariate statistical analysis and hydrochemical and isotopic investigations for evaluation of groundwater quality and its suitability for drinking and agriculture purposes: case of Oum Ali-Thelepte aquifer, central Tunisia.

    2016-03-01

    Groundwater plays a dominant role in arid regions; it is among the most available water resources in Tunisia. Located in northwestern Tunisia, Oum Ali-Thelepte is a deep Miocene sedimentary aquifer, where groundwater is the most important source of water supply. The aim of the study is to investigate the hydrochemical processes leading to mineralization and to assess water quality with respect to agriculture and drinking for a better management of groundwater resources. To achieve such objectives, water analysis was carried out on 16 groundwater samples collected during January-February 2014. Stable isotopes and 26 hydrochemical parameters were examined. The interpretation of these analytical data showed that the concentrations of major and trace elements were within the permissible level for human use. The distribution of mineral processes in this aquifer was identified using conventional classification techniques, suggesting that the water facies gradually changes from Ca-HCO3 to Mg-SO4 type and are controlled by water-rock interaction. These results were endorsed using multivariate statistical methods such as principal component analysis and cluster analysis. The sustainability of groundwater for drinking and irrigation was assessed based on the water quality index (WQI) and on Wilcox and Richards's diagrams. This aquifer has been classified as "excellent water" serving good irrigation in the area. As for the stable isotope, the measurements showed that groundwater samples lay between global meteoric water line (GMWL) and LMWL; hence, this arrangement signifies that the recharge of the Oum Ali-Thelepte aquifer is ensured by rainwater infiltration through mountains in the border of the aquifer without evaporation effects.

  18. The electricity industry perspective

    Energy Technology Data Exchange (ETDEWEB)

    Orchison, K. [Electricity Supply Association of Australia Ltd., Sydney, NSW (Australia)

    1996-12-31

    A revolution has been sweeping through the electricity supply business in Australia in the past decade and especially in the past five years. Electricity suppliers were early adherents to the pursuit of economic reform, beginning a drive towards greater efficiency in the mid-1980s and accelerating the process as government, pushed in turn by industry and commerce, took up pursuit of competitive energy markets, including radical restructuring of the State-owned utility organizations. The aim of this paper is to provide an overview of the electricity supply business. It include an outline of the major challenges confronting the electricity supply business in Australia, particularly as a result of the introduction of competitive markets in electricity and natural gas. Deregulation will see the providers of electricity and gas reposition themselves as organizations able to supply the total energy needs of customers. A de-regulated electricity market also offers cogeneration plants new opportunities to sell surplus electricity to generators, distribution businesses or directly to customers. The major frontiers facing the electricity supply business in Australia is seen to be that of productively channelling change. How this is handled has substantial implications for those who purchase electricity, suppliers of fuel to electricity generators or rivals in the marketplace. (author).

    Electrical signaling, short-term memory and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since the XIX century. We found that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The closing time of Venus flytrap by electrical stimulation is the same as mechanically induced closing. Transmission of a single electrical charge between a lobe and the midrib causes closure of the trap and induces an electrical signal propagating between both lobes and midrib. The Venus flytrap can accumulate small subthreshold charges, and when the threshold value is reached, the trap closes. Repeated application of smaller charges demonstrates the summation of stimuli. The cumulative character of electrical stimuli points to the existence of short-term electrical memory in the Venus flytrap.

  20. Economics of electricity

    Science.gov (United States)

    Erdmann, G.

    2015-08-01

    The following text is an introduction into the economic theory of electricity supply and demand. The basic approach of economics has to reflect the physical peculiarities of electric power that is based on the directed movement of electrons from the minus pole to the plus pole of a voltage source. The regular grid supply of electricity is characterized by a largely constant frequency and voltage. Thus, from a physical point of view electricity is a homogeneous product. But from an economic point of view, electricity is not homogeneous. Wholesale electricity prices show significant fluctuations over time and between regions, because this product is not storable (in relevant quantities) and there may be bottlenecks in the transmission and distribution grids. The associated non-homogeneity is the starting point of the economic analysis of electricity markets.

    1986-01-01

    A thermoacoustic magnetohydrodynamic electrical generator includes an intrinsically irreversible thermoacoustic heat engine coupled to a magnetohydrodynamic electrical generator. The heat engine includes an electrically conductive liquid metal as the working fluid and includes two heat exchange and thermoacoustic structure assemblies which drive the liquid in a push-pull arrangement to cause the liquid metal to oscillate at a resonant acoustic frequency on the order of 1,000 Hz. The engine is positioned in the field of a magnet and is oriented such that the liquid metal oscillates in a direction orthogonal to the field of the magnet, whereby an alternating electrical potential is generated in the liquid metal. Low-loss, low-inductance electrical conductors electrically connected to opposite sides of the liquid metal conduct an output signal to a transformer adapted to convert the low-voltage, high-current output signal to a more usable higher voltage, lower current signal.

  8. Essays on electricity theft

    Science.gov (United States)

    Steadman, Keva Ullanda

    Electricity theft is a relatively unknown crime with high economic costs. In this dissertation, I try to identify the factors that motivate persons to steal electricity. First, I use a panel dataset of 97 countries spanning the five year period 2003--2007 to estimate a model that describes the effect of the unemployment rate, GDP per capita, male population and urbanization on theft, robbery and homicide rates. The results are consistent with previous empirical work on crime and economic opportunity. The second and main contribution of this paper is to estimate the same model using distribution loss as a proxy for electricity theft. The results show that the unemployment rate, a key explanatory economic factor for crime, cannot explain variation in electricity theft, although there is some evidence, albeit weak, supporting correlation in rich countries. Therefore, policies that target the reduction of property crime through a reduction in unemployment will have no effect on electricity theft. The third contribution relates to the role that political institutions play in the incentives to steal electricity. After control for socioeconomic factors, I find that there is no relationship between political governance indicators and electricity theft. In the second and third chapters, I compare the United States, a high income, low electricity theft country with Jamaica, a middle income, high electricity theft country. The effect of unemployment on electricity theft mirrors the results found in the first chapter. In the United States, electricity theft is affected by changes in economic conditions but in Jamaica, it is not. These results suggest that the state of institutions plays a role in how social norms are determined. Poor countries will be more likely than rich countries to have weak institutions with social norms that encourage electricity theft.

  8. Electrical Networks: An Introduction

    Science.gov (United States)

    Pahwa, S.; Youssef, M.; Scoglio, C.

    A world without electricity is beyond our imagination. Starting from the prehistoric times, man has made much progress in every walk of life. We have become accustomed to getting everything at the flick of a switch, touch of a button, or turn of a knob. While we have become so used to enjoying the benefits of electricity, it is not easy to imagine how electricity travels from its source to our homes and offices. It sometimes has to cover large distances through a complex network of transmission lines and power substations to provide us the facilities and entertainment that we take for granted. This network which transports electricity from the source to the consumers is called the electrical network. The electrical network is a collective term for different components such as transformers, transmission lines, substations, and different stages and sub-networks devoted to generation, transmission, and distribution. Sometimes, there may be sub-transmission and secondary distribution networks too. A simple schematic of an electric network is shown in Fig. 8.1. In the past decade, analysis of the electrical power system as a complex network has been an evolving and challenging topic of research.

  13. Electricity Storage. Technology Brief

    Electricity storage is a key technology for electricity systems with a high share of renewables as it allows electricity to be generated when renewable sources (i.e. wind, sunlight) are available and to be consumed on demand. It is expected that the increasing price of fossil fuels and peak-load electricity and the growing share of renewables will result in electricity storage to grow rapidly and become more cost effective. However, electricity storage is technically challenging because electricity can only be stored after conversion into other forms of energy, and this involves expensive equipment and energy losses. At present, the only commercial storage option is pumped hydro power where surplus electricity (e.g. electricity produced overnight by base-load coal or nuclear power) is used to pump water from a lower to an upper reservoir. The stored energy is then used to produce hydropower during daily high-demand periods. Pumped hydro plants are large-scale storage systems with a typical efficiency between 70% and 80%, which means that a quarter of the energy is lost in the process. Other storage technologies with different characteristics (i.e. storage process and capacity, conversion back to electricity and response to power demand, energy losses and costs) are currently in demonstration or pre-commercial stages and discussed in this brief report: Compressed air energy storage (CAES) systems, Flywheels; Electrical batteries; Supercapacitors; Superconducting magnetic storage; and Thermal energy storage. No single electricity storage technology scores high in all dimensions. The technology of choice often depends on the size of the system, the specific service, the electricity sources and the marginal cost of peak electricity. Pumped hydro currently accounts for 95% of the global storage capacity and still offers a considerable expansion potential but does not suit residential or small-size applications. CAES expansion is limited due to the lack of suitable

  14. Electric turbocompound control system

    Energy Technology Data Exchange (ETDEWEB)

    Algrain, Marcelo C. (Dunlap, IL)

    2007-02-13

    Turbocompound systems can be used to affect engine operation using the energy in exhaust gas that is driving the available turbocharger. A first electrical device acts as a generator in response to turbocharger rotation. A second electrical device acts as a motor to put mechanical power into the engine, typically at the crankshaft. Apparatus, systems, steps, and methods are described to control the generator and motor operations to control the amount of power being recovered. This can control engine operation closer to desirable parameters for given engine-related operating conditions compared to actual. The electrical devices can also operate in "reverse," going between motor and generator functions. This permits the electrical device associated with the crankshaft to drive the electrical device associated with the turbocharger as a motor, overcoming deficient engine operating conditions such as associated with turbocharger lag.

    Futurist writing about technology emerged in the late 19th century at the same time as new kinds of electrical technology were making utopian futures seem practically attainable. Electrical writers and novelists alike thus borrowed from the popular "science" fiction of Jules Verne, Edward Bellamy and others to try to create self-fulfilling prophecies of a future in which electrical gadgets and machines met all major practical needs of civilization. To the extent that many parts of our world are populated by the hardware that they forecast, they succeeded in their goal.

  5. Coaxial Electric Heaters

    Science.gov (United States)

    Strekalov, Dmitry; Matsko, Andrey; Savchenkov, Anatoliy; Maleki, Lute

    2008-01-01

    Coaxial electric heaters have been conceived for use in highly sensitive instruments in which there are requirements for compact heaters but stray magnetic fields associated with heater electric currents would adversely affect operation. Such instruments include atomic clocks and magnetometers that utilize heated atomic-sample cells, wherein stray magnetic fields at picotesla levels could introduce systematic errors into instrument readings. A coaxial electric heater is essentially an axisymmetric coaxial cable, the outer conductor of which is deliberately made highly electrically resistive so that it can serve as a heating element. As in the cases of other axisymmetric coaxial cables, the equal magnitude electric currents flowing in opposite directions along the inner and outer conductors give rise to zero net magnetic field outside the outer conductor. Hence, a coaxial electric heater can be placed near an atomic-sample cell or other sensitive device. A coaxial electric heater can be fabricated from an insulated copper wire, the copper core of which serves as the inner conductor. For example, in one approach, the insulated wire is dipped in a colloidal graphite emulsion, then the emulsion-coated wire is dried to form a thin, uniform, highly electrically resistive film that serves as the outer conductor. Then the film is coated with a protective layer of high-temperature epoxy except at the end to be electrically connected to the power supply. Next, the insulation is stripped from the wire at that end. Finally, electrical leads from the heater power supply are attached to the exposed portions of the wire and the resistive film. The resistance of the graphite film can be tailored via its thickness. Alternatively, the film can be made from an electrically conductive paint, other than a colloidal graphite emulsion, chosen to impart the desired resistance. Yet another alternative is to tailor the resistance of a graphite film by exploiting the fact that its resistance

    Manipulation of magnetically ordered states by electrical means is a promising approach towards novel spintronics devices. We report on the electric control of surface magnetism in Cr2O3 thin films and uniaxial anisotropy in ferroelectric/ferromagnetic heterostructures, respectively. Artificial magnetoelectricity is realized in a BaTiO3/Fe heterostructure. Here, thermally induced coercivity changes of the Fe hysteresis loop are used to derive the stress imposed by the ferroelectric BaTiO3 substrate on the adjacent Fe film. Electrically induced coercivity changes give rise to a giant magnetoelectric susceptibility in the vicinity of the magnetic coercive field.

Although these three pure compounds had different crystal structures, they exhibited similar luminescence properties. For Eu3+-activated samples, the broad excitation band centered at 217 nm could be attributed to the CT transition between O2- (2p6) and Eu3+ ions. For Tb3+-doped samples, two groups of f-d transitions were observed, where a strong broad band at 221 nm was due to the spin-allowed f-d transition. Energy transfer from O2-to Dy3+was not observed in Dy3+-doped phosphors, probably because it overlapped considerably with the CT transition from O2- to Zr4+at 187 nm.

  1. Electrically driven optical antennas

    Science.gov (United States)

    Kern, Johannes; Kullock, René; Prangsma, Jord; Emmerling, Monika; Kamp, Martin; Hecht, Bert

    2015-09-01

    Unlike radiowave antennas, so far optical nanoantennas cannot be fed by electrical generators. Instead, they are driven by light or indirectly via excited discrete states in active materials in their vicinity. Here we demonstrate the direct electrical driving of an in-plane optical antenna by the broadband quantum-shot noise of electrons tunnelling across its feed gap. The spectrum of the emitted photons is determined by the antenna geometry and can be tuned via the applied voltage. Moreover, the direction and polarization of the light emission are controlled by the antenna resonance, which also improves the external quantum efficiency by up to two orders of magnitude. The one-material planar design offers facile integration of electrical and optical circuits and thus represents a new paradigm for interfacing electrons and photons at the nanometre scale, for example for on-chip wireless communication and highly configurable electrically driven subwavelength photon sources.

    Hybrid electric power trains may revolutionize today's ground passenger vehicles by significantly improving fuel economy and decreasing emissions. The NASA Lewis Research Center is working with industry, universities, and Government to develop and demonstrate a hybrid electric vehicle. Our partners include Bowling Green State University, the Cleveland Regional Transit Authority, Lincoln Electric Motor Division, the State of Ohio's Department of Development, and Teledyne Ryan Aeronautical. The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

  20. Electric generators: Roesel

    Energy Technology Data Exchange (ETDEWEB)

    Segaser, C.L.

    1977-04-01

    A new and unique type of electrical generator is described that will provide constant frequency output (within 0.01% or better) regardless of rotational speed variations. It accomplishes this with no added bulk over conventional generators, and with excellent efficiency. The same principle that permits constant frequency output also provides the means for output voltage regulation with varying drive speed and/or varying load. Onsite power generation aspects of the Integrated Community Energy Systems (ICES) concept include the requirement to follow community electric loads and the possible use of internal combustion piston engines with waste heat recovery to drive electric generators. The diesel engine is a prime candidate from commercially available technologies for which part-load shaft efficiency is better at reduced speed than for constant-speed operation required by conventional AC generators. The unique characteristics of the Roesel generator allow prime mover speed to decrease with load and offer improved engine-generator system efficiency in ICES applications.

  3. Electrical Conductivity in Textiles

    Science.gov (United States)

    2006-01-01

    Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA. Conductive fibers provide lightweight alternatives to heavy copper wiring in a variety of settings, including aerospace, where weight is always a chief concern. This is an area where NASA is always seeking improved materials. The fibers are also more cost-effective than metals. Expenditure is another area where NASA is always looking to make improvements. In the case of electronics that are confined to small spaces and subject to severe stress, copper is prone to breaking and losing connection over time. Flexible conductive fibers eliminate that problem. They are more supple and stronger than brittle copper and, thus, find good use in these and similar situations. While clearly a much-needed material, electrically conductive fibers are not readily available. The cost of new technology development, with all the pitfalls of troubleshooting production and the years of testing, and without the guarantee of an immediate market, is often too much of a financial hazard for companies to risk. NASA, however, saw the need for electrical fibers in its many projects and sought out a high-tech textile company that was already experimenting in this field, Syscom Technology, Inc., of Columbus, Ohio. Syscom was founded in 1993 to provide computer software engineering services and basic materials research in the areas of high-performance polymer fibers and films. In 1999, Syscom decided to focus its business and technical efforts on development of high-strength, high-performance, and electrically conductive polymer fibers. The company developed AmberStrand, an electrically conductive, low-weight, strong-yet-flexible hybrid metal-polymer YARN.

    1997-03-01

    The objective of the present study is to determine which factors influence electricity consumption behavior of Swedish households, the level of knowledge about electricity use and the willingness to pay for the use of electricity. In Sweden, as in many other developed countries, the need for electric power is constantly increasing. The major reason for this increase in electricity consumption is the lifestyle of a modern society. A feature in the nuclear power discussion is that the government in Sweden is having a hard time to establish how to phase-out all nuclear power plants by 2010. An additional major change in Swedish energy policy is the deregulation of the electricity market, which started in the beginning of 1996. There is an increased demand for strategies to save electricity among households. The results of this study stress the difficulties in reducing electricity consumption and to develop new electricity saving strategies in Sweden 125 refs, 6 figs, 21 tabs

Action potential-mediated inhibition of photosynthesis and stimulation of respiration is confined only to the trap and was not recorded in adjacent photosynthetic lamina. We showed that the main primary target of electrical signals on assimilation is in the dark enzymatic reaction of photosynthesis. Without doubt, the electrical signaling is costly, and the possible co-existence of such type of signals and photosynthesis in plant cell is discussed. PMID:21558815

  20. First in situ measurement of electric field fluctuations during strong spread F in the Indian zone

    Directory of Open Access Journals (Sweden)

    H. S. S. Sinha

    Full Text Available An RH-560 rocket flight was conducted from Sriharikota rocket range (SHAR (14°N, 80°E, dip 14°N along with other experiments, as a part of equatorial spread F (ESF campaign, to study the nature of irregularities in electric field and electron density. The rocket was launched at 2130 local time (LT and it attained an apogee of 348 km. Results of vertical and horizontal electric field fluctuations are presented here. Scale sizes of electric field fluctuations were measured in the vertical direction only. Strong ESF irregularities were observed in three regions, viz., 160-190 km, 210-257 km and 290-330 km. Some of the valley region vertical electric field irregularities (at 165 km and 168 km, in the intermediate-scale size range, observed during this flight, show spectral peak at kilometer scales and can be interpreted in terms of the image striation theory suggested by Vickrey et al.> The irregularities at 176 km do not exhibit any peak at kilometer scales and appear to be of a new type. Scale sizes of vertical electric field fluctuations showed a decrease with increasing altitude. The most prominent scales were of the order of a few kilometers around 170 km and a few hundred meters around 310 km. Spectra of intermediate-scale vertical electric field fluctuations below the base of the F region (210-257 km showed a tendency to become slightly flatter (spectral index n = -2.1 ± 0.7 as compared to the valley region (n = -3.6 ± 0.8 and the region below the F peak (n = -2.8 ± 0.5. Correlation analysis of the electron density and vertical electric field fluctuations suggests the presence of a sheared flow of current in 160-330 km region.

    In this paper, we apply the relationships between the macro and micro variables of traffic flow to develop an electricity consumption model for electric vehicular flow. We use the proposed model to study the quantitative relationships between the electricity consumption/total power and speed/density under uniform flow, and the electricity consumptions during the evolution processes of shock, rarefaction wave and small perturbation. The numerical results indicate that the proposed model can perfectly describe the electricity consumption for electric vehicular flow, which shows that the proposed model is reasonable.

  6. Electric Guitar and Violin

    Science.gov (United States)

    Gough, Colin

    Almost all the instruments described in this book have their origins in historical cultures dating back over many centuries. In contrast, the electric guitar and violin are clearly twentieth-century innovations. They are products of the electronics age following invention of the rectifying thermionic valve (tube) by John Ambrose Fleming in 1904, the amplifying triode valve (tube) by Lee de Forest in 1907, and the vacuum-filled amplifying valve (tube) by Irving Langmuir in 1915. By 1916, such valves were already being used in radio receivers, and important advances were being made in microphone, amplifier, and loudspeaker design. This, and the increasingly wide distribution of mains electricity in the 1920s, provided the technology and infrastructure for the development of the electric guitar and violin and their lower-pitched relations - the bass guitar, viola, cello, and string-bass. Although we focus here on the electric guitar and violin, almost everything discussed in this chapter is also relevant to their lower-pitched relations.

    Technologic innovations enable management of medical equipment and power supply systems, with improvements that can affect the technical aspects, economics, and quality of medical service. Herein are outlined some technical guidelines, proposed by Istituto Superiore per la Prevenzione e la Sicurezza del Lavoro, for increasing the effectiveness of the power supply system and the safety of patients and surgeons in the operating room, with particular focus on transplantation. The dependence of diagnoses and therapies on operation of the electrical equipment can potentially cause great risk to patients. Moreover, it is possible that faulty electrical equipment could produce current that may flow through the patient. Because patients are particularly vulnerable when their natural protection is considerably decreased, as during transplantation or other surgery, power supply systems must operate with a high degree of reliability and quality to prevent risk, and must be designed to reduce hazards from direct and indirect contact. Reliability of the power supply system is closely related to the quality of the project, choice of materials, and management of the system (eg, quality and frequency of servicing). Among the proposed guidelines, other than normal referencing, are (1) adoption of a monitoring system to improve the quality of the electrical parameters in the operating room, (2) institution of emergency procedures for management of electrical faults, (3) a procedure for management of fires in the operating room, (4) and maintenance interventions and inspections of medical devices to maintain minimal requirements of safety and performance.

  13. Topics on electricity trade

    Energy Technology Data Exchange (ETDEWEB)

    Skytte, K.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

In addition, this study also aimed to identify differences in students' levels of awareness of the importance of transferable skills and the difference levels of awareness between male and female students. Research method used in this study was quantitative survey by using questionnaire. Data were analysed by finding the mean and an independent t-test. The results showed that  students' levels of awareness of the importance of transferable skills and the mastery levels of these skills were at a high and there were significant differences between female and male students' levels of awareness of the importance of transferable skills. However, the analysis showed no difference in the levels of dominance. Overall, greater awareness will help students to master the skills perfectly. It can also be used as a guide for students to identify elements and features that are required by employers nowadays.

    The conversion of heat energy into electrical energy by a small compact device is descrtbed. Where the heat energy is supplied by a radioactive material and thermopIIes convert the heat to electrical energy. The particular battery construction includes two insulating discs with conductive rods disposed between them to form a circular cage. In the center of the cage is disposed a cup in which the sealed radioactive source is located. Each thermopile is formed by connecting wires from two adjacent rods to a potnt on an annular ring fastened to the outside of the cup, the ring having insulation on its surface to prevent electrica1 contact with the thermopiles. One advantage of this battery construction is that the radioactive source may be inserted after the device is fabricated, reducing the radiation hazard to personnel assembling the battery.
