Chapter II introduced online cocitation counts retrieval using Dialog Classic and citation index files. Certainly Dialog Classic is an attractive alternative in that the user is using the readily available bibliographic databases and retrieval software. The majority of ACA research has used ISI databases and Dialog Classic to retrieve cocitation counts. However, this approach has well-known technical limitations as discussed earlier. They include the issue of Multiple Authorship, Name-Homographs, and Synonyms. This chapter introduces an alternative approach to retrieving a cocitation count from the custom databases through the system we have designed and implemented. Custom database and retrieval systems need time and investment to develop, but they can manage most of the technical limitations discussed. The book presents two other alternative approaches that can be used to retrieve cocitation counts in lieu of using ISI citation index files and Dialog Classic. This chapter introduces the fox-base approach in developing custom databases and the cocitation matrix generation system. The first part is concerned with the design of databases. The second part describes the cocitation retrieval system. We also discuss how our system can eliminate or minimize the technical limitations of the Thomson ISI database and Dialog Classic Software system.

Keyword search is typically associated with information retrieval systems. However, recently, keyword search has been expanded to relational databases and RDF datasets, as an attractive alternative to traditional database access. With this motivation, this paper first introduces a platform for data and knowledge retrieval, called DANKE, concentrating on the keyword search component. It then describes an application that uses DANKE to implement keyword search over two COVID-19 data scenarios.

It is important that the modern-day researcher and engineer stay abreast of technology in his field, but this task is made very difficult by the recent flood of scientific and technical information. Coping with the information explosion requires the use of computerized information systems. This paper reviews computer-based information retrieval systems in engineering and focuses specifically on databases of literature and information relevant to tribologists and lubrication engineers. These databases are listed and their characteristics are discussed. Results of a sample computer-based literature search are included. It is shown that no single database has complete coverage of all aspects of tribology and that several databases should be searched to get all available information on a subject.

Gemcitabine And Cisplatin

6027 Background: The current standard of treatment in locally advanced nasopharyngeal cancer is concurrent chemoradiation, however recent addition of induction chemotherapy in the already established regimen has presented an attractive alternative approach. We report on survival with induction Gemcitabine and Cisplatin (GC) followed by chemoradiation (CRT) in the treatment of advanced nasopharyngeal carcinoma. Methods: Between 2005 and 2015, 300 patients (M 70%: F 30%) with histologically confirmed nasopharyngeal carcinoma. Histological subtypes WHO I 4% (13) and WHO III 96% (287). AJCC (7th edition) stage was Stage III 28% (85) and Stage IV 72% (215) patients. IC included a 2 drug combination; intravenous gemcitabine 1000 mg/m2 on day 1 and 8 and cisplatin 75 mg/m2 on day 1 only. Radiotherapy was given as a phase treatment to a total dose of 70 Gy in 35 fractions. Concurrent three weekly cisplatin (75 mg/m2) was administered to all patients. Results: Median follow up time was 30 months. The 5-year overall survival (OS), loco regional control (LRC) and relapse free survival (RFS) rates were 70% (95% CI 6.43 – 7.52), 69% (95% CI 6.52 – 7.64) and 52% (95% CI 5.25 – 6.34) respectively. One hundred and seven patients failed treatment; local or loco-regional 39% (42), regional 16% (17) and distant 45% (48). Conclusions: We conclude that induction gemcitabine and cisplatin followed by chemo-radiation is an effective regimen in management of nasopharyngeal carcinoma, meriting further investigation in randomized clinical trials.

Cooling Methods

The reduction of electronic components towards the nano-scale drives the development of novel cooling methods to keep up with the increasing thermal demands of the electronics industry. Since transistor dimensions are shrinking to the order of 1–10 nm, pinpointed cooling may be required for maximum efficiency. Many nano-scale cooling methods are difficult to observe in direct experimentation, so simulation techniques present an attractive alternative approach. In this respect, molecular dynamics (MD) simulations of nano-droplet impingement on a solid surface is being investigated as a potential means for pinpointed cooling. Various observations of thermophysical phenomena associated with the impingement are discussed, including the temperature rise at the collision point, the acceleration of the droplet prior to impact, and and the ordering of molecules in the liquid due to the influence of the solid.

AbstractThe widely used anticoagulant pharmaceutical, heparin, is a polydisperse, heterogeneous polysaccharide. Heparin is one of the essential medicines defined by the World Health Organisation but, during 2007-2008, was the subject of adulteration. The intrinsic heterogeneity and variability of heparin makes it a challenge to monitor its purity by conventional means. This has led to the adoption of alternative approaches for its analysis and quality control, some of which are based on multivariate analysis of 1H NMR spectra, or exploit correlation techniques. Such NMR spectroscopy-based analyses, however, require costly and technically demanding NMR instrumentation. Here, an alternative approach based on the use of attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR) combined with multivariate analysis is proposed. FTIR-ATR employs more affordable and easy-to-use technology and, when combined with multivariate analysis of the resultant spectra, readily differentiates between glycosaminoglycans of different types, between heparin samples of distinct animal origins and enables the detection of both known heparin contaminants, such as over-sulphated chondroitin sulfate (OSCS), as well as other alien sulphated polysaccharides in heparin samples to a degree of sensitivity comparable to that achievable by NMR. The approach will permit the rapid and cost-effective monitoring of pharmaceutical heparin at any stage of the production process and indeed, in principle, the quality control of any heterogeneous or variable material.

Flooding periodicity is crucial for biomass production and ecosystem functions in wetland areas. Local monitoring networks may be enriched by spaceborne derived products with a temporal resolution of a few days. Unsupervised computer vision techniques are preferred, since human interference and the use of training data may be kept to a minimum. Recently, a novel automatic local thresholding unsupervised methodology for separating inundated areas from non-inundated ones led to successful results for the Doñana Biosphere Reserve. This study examines the applicability of this approach to Camarque Biosphere Reserve, and proposes alternatives to the original approach to enhance accuracy and applicability for both Camargue and Doñana wetlands in a scientific quest for methods that may serve accurately biomes at both protected areas. In particular, it examines alternative inputs for automatically estimating thresholds while applying various algorithms for estimating the splitting thresholds. Reference maps for Camargue are provided by local authorities, and generated using Sentinel-2 Band 8A (NIR) and Band 12 (SWIR-2). The alternative approaches examined led to high inundation mapping accuracy. In particular, for the Camargue study area and 39 different dates, the alternative approach with the highest overall Kappa coefficient is 0.84, while, for the Doñana Biosphere Reserve and Doñana marshland (a subset of Doñana Reserve) and 7 different dates, is 0.85 and 0.94, respectively. Moreover, there are alternative approaches with high overall Kappa for all areas, i.e., at 0.79 for Camargue, over 0.91 for Doñana marshland, and over 0.82 for Doñana Reserve. Additionally, this study identifies the alternative approaches that perform better when the study area is extensively covered by temporary flooded and emergent vegetation areas (i.e., Camargue Reserve and Doñana marshland) or when it contains a large percentage of dry areas (i.e., Doñana Reserve). The development of credible automatic thresholding techniques that can be applied to different wetlands could lead to a higher degree of automation for map production, while enhancing service utilization by non-trained personnel.

Getting a journal indexed reflects high-quality scientific integrity, which differentiates it from a non-indexed journal. Quantitative analysis of indexing status of a randomly selected sample of 121 predatory journals listed on https://beallslist.net/standalone-journals/ was carried out to ascertain their presence in various reputed bibliographic databases. The study's findings divulge that the presence of predatory journals in bibliographic databases is not significantly widespread. However, some indexing databases such as Emerging Sources Citation Index (ESCI) and PubMed reflect slightly greater values than anticipated and need to be scrutinized and reviewed regularly. Further, the study found that these journals incorporate many metrics under indexing/ abstracting information which are not in a true sense suitable to be categorized as indexing abstracting databases. Further, Index Copernicus, Scientific Journal Impact factor (SJIF), National Academy of Agricultural Sciences (NAAS), Global Impact Factor (GIF) are the most used Counterfeit indexing services by the journals.

Abstract Background Roma populations experience significantly poorer health than majority populations. Health outcomes are often worse than for others in similar social positions, suggesting differences are not simply the effect of poverty. Roma women are thought to be worst affected. However, data pertaining to the multiple social inequalities affecting Roma populations, their interaction and cumulative effect on health over time, have yet to be synthesised. Methods We searched four bibliographic databases (MEDLINE, Science Citation Index, Social Sciences Citation Index and Scopus), screened reference lists, consulted key informants and searched organisational websites for studies providing empirical evidence on more than one determinant of health for Roma populations in Europe. Two reviewers carried out screening, data extraction, quality appraisal and performed a narrative synthesis. Results From 2,043 bibliographic records, 37 studies met our inclusion criteria. The median number of influencing factors explored through qualitative and quantitative methodologies was 2 (range 1 - 5) and 3 (range 1 - 11), respectively. Quantitative studies focussed on poverty (10 studies) and other indicators of socio-economic status including education (13 studies), housing (9 studies) and employment (9 studies). Very few studies unpicked interactive effects instead testing each factor’s contribution to poor health independently. Qualitative studies tended to explore “Roma culture” (11 studies) and the impact of discrimination/racism on health behaviour (10 studies). There is a lack of gender-disaggregated data and little analysis of the impact of social policy on the health of Roma populations. Conclusions Evidence for associations between determinants and health outcomes among European Roma populations is patchy. Research needs to pay more attention to the health impact of social policies that have the potential to reinforce (as well as mitigate) the exclusion of Roma populations. Key messages This systematic review critically analyses the state and shape of research evidence on the multiple interacting axes of inequality that contribute to poor health among Europe’s Roma populations. There is a divergence between qualitative and quantitative studies, with the former providing some evidence on socio-economic status and the latter exploring aspects of culture and discrimination.

AbstractThe efficiency of thermoelectric technology today is limited by the properties of available thermoelectric materials and a wide variety of new approaches to developing better materials have recently been suggested. The key goal is to find a material with a large ZT, the dimensionless thermoelectric figure of merit. However, if an analogy is drawn between thermoelectric technology and gas-cycle engines then selecting different materials for the thermoelements is analogous to selecting a different working gas for the mechanical engine. And an attempt to improve ZT is analogous to an attempt to improve certain thermodynamic properties of the working-gas. An alternative approach is to focus on the thermoelectric process itself (rather than on ZT), which is analogous to considering alternate cycles such as Stirling vs. Brayton vs. Rankine etc., rather than ‘merely’ considering alternative ‘gases’. Focusing on the process is a radically different approach compared to previous studies focusing on ZT. Aspects of the thermoelectric process and alternative approaches to efficient thermoelectric conversion are discussed.
