This thesis addresses some issues associated with population dynamics in random environment. Random environment is described by a Markov process with values in a finite space and which, involve certain forces on the choice of vital rates, will lead the population dynamics. When the dynamic is modeled by a birth and death process, we will answer the question : When almost surely extinction settled ? (Bacaër and Ed-Darraz, 2014). In (Ed-Darraz and Khaladi, 2015) we are interested to the final size of an epidemic in random environment.
Chemical leaching Identification of the of pelagic sediments: carrier of Ce anomaly

Several chemical leaching experiments were carried out to characterize the REE distribution in four pelagic sediments which have negative Ce anomaly collected in Central Pacific. Extraction experiments indicate that the carrier of the negative Ce anomaly is phosphate phase. This result supports our hypothesis that a negative Ce anomaly is mainly due to fish bone debris in the Pacific equatorial pelagic sediments, in case of pelagic sediments far from the areas of hydrothermal activity . Furthermore, a positive Ce anomaly in pelagic sediments was confirmed by leaching experiment to be due to hydrogenous components (1VIn-Fe oxides). The terrigenous component (silicate phase) has a low REE content and a flat shale-normalized REE pattern.
NHE8 attenuates Ca 2 (cid:2) inﬂux into NRK cells and the proximal tubule epithelium

gar- ner insights into the renal regulation of Ca 2 (cid:2) homeostasis, we performed an mRNA microarray on kidneys from mice treated with the Ca 2 (cid:2) -sensing receptor (CaSR) agonist cinacalcet. This revealed decreased gene expression of Na (cid:2) /H (cid:2) exchanger isoform 8 (NHE8) in response to CaSR activation. These results were conﬁrmed by quan- titative real-time PCR. Moreover, administration of vitamin D also decreased NHE8 mRNA expression. In contrast, renal NHE8 protein expression from the same samples was increased. To examine the role of NHE8 in transmembrane Ca 2 (cid:2) ﬂuxes, we used the normal rat kidney (NRK) cell line. Cell surface biotinylation and confocal immu- noﬂuorescence microscopy demonstrated NHE8 apical expression. Functional experiments found 5-( N -ethyl- N -isopropyl)amiloride (EIPA)-inhibitable NHE activity in NRK cells at concentrations minimally attenuating NHE1 activity in AP-1 cells. To determine how NHE8 might regulate Ca 2 (cid:2) balance, we measured changes in intracellular Ca 2 (cid:2) uptake by live cell Ca 2 (cid:2) imaging with the ﬂuorophore Fura-2 AM. Inhibition of NHE8 with EIPA or by removing extracel- lular Na (cid:2) -enhanced Ca 2 (cid:2) inﬂux into NRK cells. Ca 2 (cid:2) inﬂux was mediated by a voltage-dependent Ca 2 (cid:2) channel rather than directly via NHE8. NRK cells express Cav1.3 and display verapamil-sensitive Ca 2 (cid:2) inﬂux and NHE8 inhibition-augmented Ca 2 (cid:2) inﬂux via a voltage-dependent Ca 2 (cid:2) channel. Finally, proximal tubules perused ex vivo demonstrated increased Ca 2 (cid:2) inﬂux in the presence of luminal EIPA at a concentration that would inhibit NHE8. The results of the present study are consistent with NHE8 regulating Ca 2 (cid:2) uptake into the proximal tubule epithelium.
Soil organic matter processes: characterization by C-13 NMR and C-14 measurements

Soil organic matter (SOM) is a central contributor to soil quality as it mediates many of the chemical, physical, and biological processes controlling the capacity of a soil to perform successfully. SOM properties (e.g. C/N ratio, macro-organic matter) have been proposed as diagnostic criteria of overall soil ﬁtness, but their use is hampered by a poor understanding of the basic biochemical principles underlying SOM processes. The objective of this project was to determine the inﬂuence of scrub oak ( Quercus dumosa Nutt.) and Coulter pine ( Pinus coulteri B. Don) vegetation on decomposition and SOM formation processes in a lysimeter installation constructed in 1936 in the San Gabriel mountains of southern California. Soil samples archived during construction of the installation, and A horizons sampled in 1987, were fractionated according to density and mineral particle size to isolate the water ﬂoatable (macro-organic matter), ﬁne silt and clay fractions. Carbon turnover rates were determined on all fractions from AMS 14 C measurements. Solid state CPMAS TOSS 13 C NMR was used to semiquantitatively characterize the chemical structure of organic matter on fresh litter and soil fractions. For the two soils, there was a progressive decrease in O-alkyl C, and an increase in alkyl and carbonyl C from the litter to the ﬂoatable, ﬁne silt and clay fractions. These compositional differences were due to the oxidative degradation of the litter material, with preferential decomposition of the cellulose and hemicellulose entities and selective preservation of recalcitrant waxes and resins. In all soil fractions, turnover rates of carbon were longer for the pine than for the oak lysimeter (up to 10 times longer). Also under pine, there was a gradual increase in turnover rate progressing from the ﬂoatable to the clay fraction, and differences in turnover rates among fractions may be explained based on differences in carbon chemistry. In contrast, under oak, rapid carbon turnover for all fractions suggested intense biological activity in this soil. # 2000 Published by Elsevier Science B.V.
Abstract: In order to analyze the possible relationship between the quantity of gingival crevicular fluid (GCF) and clinical periodontal status, the severity of gingival inflammation (gingival index (GI) scores)

In order to analyze the possible relationship between the quantity of gingival crevicular fluid (GCF) and clinical periodontal status, the severity of gingival inflammation (gingival index (GI) scores) and probing depth (PD) were recorded and GCF samples were obtained from 1111 sites. These sites were further analyzed on the basis of distinct tooth groups to evaluate the significance of particular anatomical sampling locations. Statistical analysis of cumulative data showed significant increases in GCF volume with greater GI scores and PD. Correlations between GCF volume and both of the clinical measures were also strongly positive and significant for all sites. However, significant differences in GCF volume were observed between the anterior and posterior sampling sites. Increases in volume with increasing GI and PD were more marked for incisor and canine teeth. Similarly, the relationship between the quantity of GCF and clinical periodontal status was more clear and absolute in the anterior region than in the premolar and molar areas. These findings suggest that the quantity of GCF is not constant throughout the entire dentition, and that the relationship between GCF measurements and clinical periodontal status is site-based. This unique feature of GCF seems to be an essential factor in the design of GCF-related studies. (J. Oral Sci. 42, 231-238, 2000)
THE INTERNATIONAL JOURNAL OF BUSINESS & MANAGEMENT Audit Quality and Accrual Quality in Nigerian Quoted Manufacturing Firms

quality broad definition definition. Abstract: The impact of an audit on the accounting information quality stem from its role in mitigating the falsification of the economic and financial reality of the firm. Accordingly, the financial information audited by an external auditor is inclined to have better information content, helping users in making better decisions and as such generating greater economic benefits. However, the series of corporate failures in the world has made financial report users question the audit quality for decision making. The quality of an audit has been a debated issue in recent times and evidences put forward show that lack of audit quality is among the most significant reason for financial and corporate scandals. This study investigated the effect of audit quality on accrual quality of Nigerian listed manufacturing firms. The study employed ex-post facto research design. The population of the study was 53 manufacturing firms listed on the Nigerian Stock Exchange as at 31 st December 2017. A sample of 30 firms for a period of 10 years (2008-2017) was selected purposively. Data were analyzed using mean, percentages, pooled OLS, random effect, fixed effect and generalized least square method. The study found that audit firm size and audit committee expertise exerted a significant positive influence on accrual quality, size exerted a significant negative influence on accrual, audit tenure and sector based specialization had insignificant negative effect on accrual quality, while audit firm independence and age had insignificant positive effect on accrual quality while. But the relationship between the number of audit firm engaged and accrual quality is in doubt, this relationship could not be proved or disproved based on the regression analysis result. This study concluded that audit firm size, audit tenure, sector based specialization, audit firm engaged, audit firm independence, audit committee expertise after being controlled by size and age of the firms bring about accrual quality. The study in relying on the financial report to take decisions, users of these statements should consider these major audit attributes which have been found to greatly improve the accounting numbers. audit quality looking at financial reporting compliance with General Acceptable Accounting Principle (GAAP), quality control review, bankruptcy, desk review and Stock Exchange performance (Chadegani 2011) without relying on any proxies. Regarding the control variables, the results obtained suggest a positive insignificant relationship between age of the listed manufacturing firms and accrual quality and a negative significant relationship between size of the listed manufacturing firms and accrual quality respectively. These results imply that these elements contribute both positively and negatively to the improvement of accrual quality.
Plant identification using deep convolutional networks based on principal component analysis

Plants have substantial effects in human vitality through their different uses in agriculture, food industry, pharmacology, and climate control. The large number of herbs and plant species and shortage of skilled botanists have increased the need for automated plant identification systems in recent years. As one of the challenging problems in object recognition, automatic plant identification aims to assign the plant in an image to a known taxon or species using machine learning and computer vision algorithms. However, this problem is challenging due to the inter-class similarities within a plant family and large intra-class variations in background, occlusion, pose, color, and illumination. In this thesis, we propose an automatic plant identification system based on deep convolutional networks. This system uses a simple baseline and applies principal component analysis (PCA) to patches of images to learn the network weights in an unsupervised learning approach. After multi-stage PCA filter banks are learned, a simple binary hashing is applied to output maps and the obtained maps are subsampled through max-pooling. Finally, the spatial pyramid pooling is applied to the downsampled data to extract features from block histograms. A multi-class linear support vector machine is then trained to classify the different species. The system performance is evaluated on the plant identification datasets of LifeCLEF 2014 in terms of classification accuracy, inverse rank score, and robustness against pose (translation, scaling, and rotation) and illumination variations. A comparison of our results with those of the top systems submitted to LifeCLEF 2014 campaign reveals that our proposed system would have achieved the second place in the categories of Entire, Branch, Fruit, Leaf, Scanned Leaf, and Stem, and the third place in the Flower category while having a simpler architecture and lower computational complexity than the winner system(s). We achieved the best accuracy in scanned leaves where we obtained an inverse rank score of 0.6157 and a classification accuracy of 68.25%.
Association Between Paranoia And Anorexia Nervosa In Adolescents: What Factors Are Involved?

Background: psychiatric comorbidities are of particular interest in Eating disorders. The association between anorexia nervosa and psychotic disorders is less studied than that with affective disorders (anxiety/depression). The aim of this study is to describe a psychotic symptom (paranoia) in adolescents with Eating Disorders looking at several potential explicative associated factors: eating disorder symptoms, body image concerns, depression and social anxiety. Our hypothesis is that paranoia in AN patients is more explained by the concomitant depression and social anxiety symptoms than core symptoms of the disease (eating disorder symptoms or body image concerns). Methods: this is a retrospective cross sectional study and consecutive, help-seeking adolescents admitted to the Eating Disorder service of the Integrated Pediatric Care Department, Luigi Vanvitelli University Hospital constituted the sample. Data was obtained trough retrospective collection of clinical interviews and self – report questionnaires administered by trained and expert child and adolescent psychiatrists. Results: We obtained data from 92 adolescents with Eating Disorders. Paranoia was dimensionally distributed in the sample (mean: 22,17 SD: 17,7; median 18 IQR: 7/36; range: 0-62). Our regression model explained that paranoia in this population was better explained by depression (coefficient= 0,415 SD: 0,210, p=0,052) and social anxiety symptoms (coefficient= 0,253 SD: 0,060; p<0,001) than eating disorder symptoms (coefficient= 0,092 SD: 0,107; p=0,398) and body image concerns (coefficient= 1,916 SD: 2,079; p=0,359) that did not retain their significance when all our predictive factors entered in the model. Conclusion: This study has some theoretical, clinical and treatment implications. It is important to carrying out screening for the presence of psychotic symptoms in patients with Eating Disorders. These symptoms and associated factors (depression and social anxiety) may complicate the clinical picture of the disease with the need, in certain cases, of psychopharmacological drugs and, among these, anti-psychotics. Finally in the psychotherapy context, paranoid idea may be subject of treatment for patient with EDs. trough retrospective collection of clinical interviews by adolescent psychiatrists self – report questionnaires. These tools part of routine assessment for these patients. Inclusion criteria were Diagnostic And Statistical Manual Of Mental Disorder 5th edition (DSM – 5) based clinical diagnosis of AN or Eating disorder not otherwise specified (EDs NOS). Exclusion criteria were intellectual disability and other neurodevelopmental disorders. The study was performed in accordance with the 1964 Helsinki declaration and its later amendments. Patients or their legal representatives gave consent to the clinical routine assessment.

Electronic document management system (EDMS) atau sistem persuratan elektronik saat ini sudah mulai diterapkan oleh perguruan tinggi untuk menunjang eksistensi dan meningkatkan produktivitasnya. Mengingat electronic document management system (EDMS) dapat menggantikan proses administrasi persuratan manual menjadi proses administrasi persuratan elektronik yang dapat mempercepat dan memudahkan pengguna dalam administrasi persuratan. Meskipun begitu kehadiran sistem informasi baru seperti electronic document management system (EDMS) dapat menimbulkan sikap penerimaan ataupun penolakan dari penggunanya yang mengalami keraguan atau keengganan untuk mencoba menggunakan electronic document management system (EDMS) yang baru diterapkan tersebut. Fenomena tersebutlah yang menjadi perhatian peneliti untuk mengetahui penerimaan dan penggunaan pengguna terhadap penerapan sistem persuratan yang baru saja diterapkan di Universitas Airlangga dengan nama sistem e-office. Peneliti menggunakan model unified theory of acceptance and use of technology (UTAUT) dari Venkatesh et all tahun 2013 untuk menggambarkan penerimaan dan penggunaan sistem e-office di Universitas Airlangga. Penelitian ini menggunakan metode kuantitatif multivariat dengan metode structural equation modelling (SEM) dengan tools SmartPLS. Lokasi penelitia ini di Lingkungan Universitas Airlangga Surabaya. Metode pengambilan sampel menggunakan proporsional stratified random sampling dengan jumlah sampel sebanyak 100 responden.

Sedangkan faktor lain seperti effort expectancy, gender, age, dan experience tidak berpengaruh pada penerimaan dan penggunaan pengguna terhadap sistem e-office di Universitas Airlangga, dikarenakan penggunaan sistem e-office sudah menjadi kebijakan di lingkungan Universitas Airlangga yang mewajibkan penggunanya untuk menggunakan sistem e-office dalam proses administrasi persuratan.
ADAPTING WATERFALL DESIGN TO AN EIGHT MONTH

York University’s multi-disciplinary capstone design class was established “to include significant elements of design and implementation” in such as manner as to “resemble engineering projects in practice. ” The class was restructured in summer 2016 to coincide with the introduction of fourth-year cohorts in both the Electrical and Mechanical programs. The changes were designed to more closely emulate an industrystandard approach. Choosing an industrially-accepted design methodology would provide a good framework for the project design and implementation and would be motivational to the students as they transitioned from university to professional life. In parallel, the course directors used a narrative structure, the Hero’s journey, to help students identify their pathways through capstone and to tell their capstone stories after the experience. We adapted the gating reviews for the Waterfall model often used in large government contracts. At the start of the project, students are provided a governing document (similar to a contract). Gate reviews are held at preliminary and critical design stages, test readiness and post-test review and final delivery. Every deliverable requires team reflection, similar to bidder self-evaluations on government contracts. The project concludes with an open house, similar to a product release, for students to present their projects and processes to stakeholders and the general public. This paper presents the results of the first two years of the newly revised capstone, using the Hero’s Journey metaphor and the waterfall model.

Agenda-Setting in Cross-National Coverage of COVID-19: An Analysis of Elite Newspapers in US and China with Topic Modeling

Received: 9 Jan 2021 Accepted: 16 Jun 2021 This study examines agenda-setting in US-China elite newspapers coverage of COVID-19 through topic modeling. It attempts to contribute to studies of media agenda first by demonstrating the relevance of text-mining in agenda-setting research and second by comparing how elite newspapers from different countries choose topics as part of agenda-setting when they report a single event. Topic-modeling the news corpora collected between 15 January 2020 and 15 June 2020 from the four US-China elite newspapers, the study finds that “domestic economy” and “international relations” are the two dominant topics that help shape the agenda in the Chinese newspapers, whereas “family & friends” and “daily life” are the topics playing the same role in the US newspapers. The study argues that such differences may associate with ideological gaps between the two countries in terms of “concepts of development”, “media bias” and “views of individualism”.
DETERMINANTS OF CONVENTION & CONFERENCE SITE SELECTION: THE POLISH EVENT PLANNERS' PERSPECTIVE

The paper presents results of research on Polish event planners. The overall purpose of the study is to investigate main destination selection variables Polish event planners consider important in destination selection process. The current research focused on the destination selection variables that event planners used for events they held in 2013. The research was based on structured interviews carried on in February 2013. The research group consisted of members of four leading MICE associations. Questions created for the survey were based on an extensive literature review and previous studies which concerned main destination attribute requirements. The findings of the study suggest that overall cost is important or extremely important for 81,8%, accessibility by air and by roads is important or extremely important for 87.4% respondents whereas 98,3% event planners find support services for events very important. The results of the study will help the destination marketing organizations as well as marketing professionals in hotel meeting facilities and convention centres better position their services and better understand event planners’ needs and requirements.
Skeletal Blood Flow: Implicationsfor Bone-Scan Interpretation

skeletal blood flow in tracer localization is an enigma: although a decrease in uptake is readily identified (as in the â€œphoton-deficientâ€•bone infarct) (1 ), what can be said of the importance of skeletal blood flow with respect to photon excess such as metastases, fracture, or Paget's disease, where new bone formation can also account for tracer uptake? Are there clinical situations in which increases in blood flow are a dominant factor in scan interpretation? In the past few years these and related topics have been addressed by several research groups, with some surprising results. This report will attempt to summarize these findings and to put them in clinical perspective.
NOTES Transfer of the Genes for the StyLTI Restriction-Modification System of Salmonella typhimurium to Strains Lacking Modification Ability Results in Death of the Recipient Cells and Degradation of Their DNA

The genes encoding the restriction-modification system StyLTI of Salmonella typhimurium were inserted in vivo into the conijugative. plasmid pULB21. , This allowed us to transfer the StyLTI genes at a very high frequency and to monitor the fate of recipient cells after mating. Transfer of the StyLTI restriction and modification genes into a modificationless recipient was lethal and resulted in degradation of the cell's DNA. This indicates that, in contrast to any other known restriction-modification systems, StyLTI cannot be established after horizontal transfer into a naive host.
