Integrating IAEA’s Physical Model with JRC’s The Big Table document search tool
The Physical Model (PM) is an internal multi-Volume document for the IAEA’s Department of Safeguards describing the nuclear fuel cycle. This report describes work carried out by the JRC with the IAEA to prototype the integration of the PM with The Big Table (TBT), a document search tool developed by the JRC and in use at the IAEA.
The core of TBT is an integrated collection of reference documents including regulatory documents, technical handbooks and trade nomenclatures. The documents are stored in a database. They are searchable by text in a structured way (i.e. on database fields) and also by correspondence tables that relate items by their meaning.
To integrate the Physical Model into TBT, the IAEA/SG/SGIM has first turned the PM into a tabular format. JRC has then proposed and implemented a way of coding the PM in TBT tables to better reflect the PM structure. Eleven PM Volumes have been integrated in a TBT-PM database for use by the IAEA. The PM Volumes are linked by correspondence tables to other documents in the TBT collection.
By coding the Physical Model into a TBT database format, the original intended uses of the PM are still supported. TBT can ease the consultation of the PM for evaluating States’ nuclear activities by IAEA’s analysts. TBT can be an aid for IAEA’s inspectors preparing for routine and ad hoc inspections, design information verification visits and complementary access operations. Further the PM integrated into TBT can be used as a tool for training inspectors on steps of the nuclear fuel cycle.
Finally implementing the Physical Model multi-level structure into a database-coded format opens the possibility of linking the PM to other taxonomies and collections of open sources relevant for safeguards analyses.JRC.E.8-Nuclear securit
Mobilities and alterities in Tail of a Certain Orient and its Arabic pre-translation
Esta tese tem como objetivo discutir as variadas manifestações de mobilidades culturais e suas consequentes relações de alteridades no romance Relato de um certo oriente de Milton Hatoum, partindo do suposto de que a alteridade é parte constituinte da subjetividade e da relação humana de diferença e identidade com o Outro; e, ao mesmo tempo, analisar o processo intercultural da pré-tradução para a língua árabe de quatro capítulos do Relato de um certo oriente. Nesse sentido, este trabalho está focado em dois lócus das mobilidades culturais das alteridades: a narrativa de memória da imigração e a tradução literária.This thesis aims to discuss the various manifestations of cultural mobilities and its consequent relations of alterities in the novel Tale of Certain Orient of Milton Hatoum, assuming that otherness is a constituent part of human subjectivity and its relationship of difference and identity with the Other; and at the same time we intend also to analyze the processo of intercultural pretranslation into Arabic of four chapters of the novel. In this sense, this work is focused on two locals of cultural mobilities of alterities: the narrative memory of immigration and literary translation
Transvaginal power Doppler sonography can discriminate between benign and malignant endometrial conditions in women with postmenopausal bleeding
Objective: To evaluate the role of transvaginal power Doppler sonography in differentiation between benign and malignant endometrial conditions in women with postmenopausal bleeding.
Setting: OB/GYN Dept., Suzan Mubarak University Hospital and Radiology Dept., Minia University Hospital, Minia University, Minia, Egypt.
Study design: Prospective observational study.
Patients: Eighty patients with postmenopausal bleeding.
Intervention(s): Grey scale transvaginal sonography, power Doppler study of the endometrium and endometrial-myometrial interface, and office hysteroscopy and the final diagnosis by histopathological examination of hysteroscopic guided biopsy.
Results: Endometrial power Doppler signals were positive in 69 out of the eighty patients (86.25%): 8 cases showed multiple vessel pattern -A- (10%); 19 cases with single vessel pattern -B- (23.75%); 42 cases with scattered vessel pattern -C- (52.5%) while in the remaining 11 cases (13.75%), no power Doppler signals were detected. The hysteroscopic findings were endometrial polyp in 16 cases (20%), atrophic endometrium in 14 cases (17.5%), hyperplasic endometrium in 32 cases (40%), submucus fibroid in 6 cases (7.5%), cervical polyp in 3 cases (3.75%) and suspicious endometrium for malignancy in 8 cases (10%). Hysteroscopy was more accurate in cases with intra-cavitary masses (polyps and submucous fibroids) than power Doppler, but power Doppler had a more predictive value for malignant endometrium.
Conclusion: Power Doppler blood flow mapping of the endometrium in women with postmenopausal bleeding is useful to discriminate carcinoma from other endometrial pathologies
Post-immunization immunohistochemical expression of Caspase 3 and p53 apoptotic markers in experimental hydatidosis
Abstract The aim of this study was to investigate post-immunization apoptotic changes in experimental hydatidosis, using Caspase 3 and p53 immunohistochemical markers. Two groups of rabbits were immunized with a crude antigen (group 1) or a partially purified antigen (group 2) and were compared to an infected non-immunized control group. More effective immune responses were obtained in group 2 than group 1, signified by fewer and smaller cystic lesions and more severe destructive changes. Normal growth of cysts was attained in the control group, with no expression of apoptotic markers. Significantly higher expression of Caspase 3 and p53 were observed in group 1 compared to group 2, as indicated by OD and area percentage, respectively (Group 1 Caspase 3: 0.89±0.21, 93.5%±6.2; Group 1 p53: 0.46±0.18, 53.26%±11.6; Group 2 Caspase 3: 0.52±0.15, 49.23%±11.7; Group 2 p53: 0.19±0.4, 18.17%±7.3). Vaccine-induced immune responses and cellular damage may underlie the expression of apoptotic markers that appeared to result in a degenerative and atrophic course of action upon immunization. The results of the current study emphasize the importance of immunization for the stimulation of protective immune responses and in preventing mechanisms of evasion to ensure normal cell growth. A cost/benefit control program that implements proper vaccine preparations should be further assessed for complete elimination of severe infections in endemic areas
Post-operative Pain After Vital Pulpotomy of Primary Molars Using Allium Sativum Oil Versus Mineral Trioxide Aggregate: A Randomized Pilot Clinical Study
Aim: To evaluate clinical and radiographic performance of Allium Sativum oil dressed in Zinc Oxide versus Mineral trioxide aggregate as pulp dressing agent in pulpotomized lower primary molar teeth. Methodology: This randomized pilot clinical trial included 30 lower primary molars indicated for vital pulpotomy and randomly allocated into two equal groups (n=15): Group (I): pulpotomy using A. Sativum oil dressed in ZnO and Group (II): pulpotomy using Mineral trioxide aggregate as pulpotomy agent. All molars were covered with stainless steel crowns and clinical and radiographic assessment was done at 3, 6, 9 and 12 months interval by help of predetermined criteria. Results: Overall clinical success rate of Group (I) and Group (II) at the end of 12 months follow-up was (93.3%) and (100.0%) respectively. There was no statistical significance difference between two groups regarding overall clinical success rate. The overall radiographic success rate at the end of 12 months was (40.0%) and (100.0%) respectively. There was a statistical significant difference regarding overall radiographic success rate at 9 and 12 months follow-up. The overall success rate of Group (I) and Group (II) at the end of 12 months was (40.0%) and (100.0%) showing a statistically significant difference between the two groups

The Transmuted Weibull Lomax Distribution: Properties and Application
A new five parameter model is proposed and stutied. The new distribution generalizes the Weibull Lomax distribution introduced by Tahir et al. (2015) and is referred to as transmuted Weibull Lomax (TWL) distribution. Various structural properties of the new model including ordinary and incomplete moments, quantiles, generating function, probability weighted moments, Rényi and q-entropies and order statistics are derived. We proposed the method of maximum likelihood for estimating the model parameters. The usefulness of the new model is illustrated through an application to a real data set
Prevalence of Helicobacter pylori cagA
H. pylori infection causes peptic ulcer, chronic gastritis, mucosa-associated lymphoid tissue lymphoma, and gastric carcinoma. It has several virulence factors such as cytotoxin-associated gene A(cagA) and the induced by contact with epithelium antigen (iceA). We aimed to explore the relationship between cagA and iceA of H. pylori and gastrointestinal diseases. One hundred and eighteen patients who attended Gastrointestinal Endoscopy Unit at Zagazig University Hospitals, Egypt, were included in this study. Two gastric biopsies were collected and evaluated by rapid urease test (RUT) and PCR. cagA and iceA genes were amplified by PCR. We found that 54 patients (45.76%) were positive by both RUT and PCR. cagA and iceA genes were present in 57.4% and 46.29% of the studied patients, respectively. cagA was the most prevalent gene in gastritis (33.3%) and peptic ulcer (68.7%). iceA1/iceA2 positive genes were the most prevalent in gastric cancer (75%). iceA1 gene was present in 38.7% of cagA positive cases, but iceA2 gene was present in 45.2% of cagA positive cases. iceA1/iceA2 positive genes were present in 29% of cagA positive cases. In conclusion, cagA and iceA genes could be used as markers for severe gastrointestinal diseases. iceA gene was strongly related to cagA gene
