Design of a knowledge and management system for starch bioconversion
2011
Abstract In this paper a knowledge acquisition and management system (KAMS) which allows the collection, analysis, ordering and storage of informations generated at starch liquefaction was developed. KAMS was structured on three levels: PostgreSQL as a backend, D2RQ as middle tier and Seaside as frontend. The system was used to store knowledge about the liquefaction process with the goal to be used as a decision support system in chosing the condition for this operation. The tests had shown that the implemented KAMS provides support for: Distributed acquisition of the scientific data generated by the researchers; Structured data storage; Support for the generation and storage of knowledge o…
Business Constraints Integration in a Search Engine Optimization Fuzzy Decision Support System
2017
The Internet has dramatically changed the way companies can reach their clients. Henceforth, to develop their business online, companies have to drive qualified traffic to their website. For this, their website must be visible in the first pages of search engine results. Search Engine Optimization (SEO) permits the improvement of the position of a website on the search engines results pages. However, the practice of SEO is complex, and results are uncertain, because search engines do not communicate much about their ranking methods. Moreover, this activity takes time, and requires the implementation of modifications that can alter the visual appearance of the webpages. This paper proposes a…
LC3: A spatio-temporal and semantic model for knowledge discovery from geospatial datasets
2015
International audience; There is a need for decision-makers to be provided with both an overview of existing knowledge, and information which is as complete and up-to-date as possible on changes in certain features of the biosphere. Another objective is to bring together all the many attempts which have been made over the years at various levels (international, Community, national and regional) to obtain more information on the environment and the way it is changing. As a result, remote sensing tools monitor large amount of land cover informations enabling study of dynamic processes. However the size of the dataset require new tools to identify pattern and extract knowledge. We propose a mo…
The funding sources of implantology research in the period 2008-2017: A bibliometric analysis
2019
BACKGROUND Implant dentistry is subject to major economic pressures as a result of the growth in the manufacturing and commercialization of dental implants. PURPOSE To examine research funding in implant dentistry by means of a bibliometric analysis of articles indexed in Web of Science (WoS) published during the period 2008-2017. MATERIALS AND METHODS The search was conducted applying the truncated term "implant*" in the WoS dentistry area. Only items labeled as "article" or "review" were selected. Records were manually refined and normalized to unify terms and to remove typographical, transcription, and/or indexing errors. RESULTS A total of 14 255 records were identified for analysis. Ab…
Dental emergency care in Spain during the state of alarm due to COVID-19 pandemic.
2020
Background: The first state of alarm due to COVID-19 in Spain led to limit dental treatment exclusively to emergencies. The objective of the survey was to evaluate the amount and type of emergencies attended during this period, as well as to know how they were solved, and what measures were adopted to carry out dental care in these exceptional circumstances. Material and Methods: This cross-sectional study included 312 Spanish dentists, who fulfilled an online questionnaire with 22 closed questions, divided into five sections regarding to various aspects of professional dental profile and emergency care. Descriptive statistic and Chi-square tests were performed (p<0.05). Results: 75.64% of …
The fate of organic matter sources in coastal environments: a comparison of three Mediterranean lagoons
2008
Trophic processes in coastal lagoons are strongly influenced by freshwater inputs and water exchanges with the sea. In recent years, stable isotope analysis has become a widespread and reliable method for the examination of trophic structure over time and space, also in complex ecosystems such as coastal lagoons. Stable isotopes of carbon and nitrogen were studied in primary producers and consumers to identify organic matter source pools from terrestrial, benthic and pelagic environments and to characterise the trophic structure in three Mediterranean coastal lagoons (Lake Fusaro, the Lake of Sabaudia and Stagnone di Marsala). The results highlighted the negligible importance of terrestrial…
Experimental Study on the Diet of Mosquitofish (Gambusia holbrooki) under Different Ecological Conditions in a Shallow Lake
2004
We studied the diet of the eastern mosquitofish Gambusia holbrooki with in situ experimental mesocosms located in a shallow lake. Different nutrient concentrations (phosphorus and nitrogen) and fish population densities were tested. Our results confirm that it is a planktivorous species, with also a great ingestion of algae and detritus. Nutrient fertilization caused almost no changes in this species feeding behavior, but larger mosquitofish stocks induced a shift to zooplanktivory and a decline in detritivory. When macrophytes were present, the predation effect focused on zooplankton and plant-associated animals, otherwise predation on bottom macroinvertebrates increased. Females preyed up…
Relationship of developmental psychology with Health in the scientific journals of the WoS and Scopus
2018
[ES]: El objetivo del presente trabajo es dar respuesta, a partir del estudio de las revistas recogidas en la categoría de Developmental Psychology de la WoS y de Scopus, a la relación existente entre la Psicología del desarrollo y la Salud. Se analizaron un total de 291 revistas de la categoría Developmental Psychology del JCR (SSCI) y del SJCR. El 21.7% de las revistas de la categoría Developmental Psychology de la WoS y el 16.1% de Scopus son clasificadas también en áreas relacionadas con la salud, como Clinical Psychology, Psychiatry, Psychoanalysis Psychology, Pediatrics y Rehabilitation. La categoría mayormente representada es Clinical Psychology, con un 20.3% de revistas en el JCR (S…
Recent advances on nanomaterial based electrochemical and optical aptasensors for detection of cancer biomarkers
2018
Abstract Cancer is a real menace to all societies globally since it is the leading cause of premature mortality in men and women. The incidence of malignancies is enhancing as a result of plenty factors. Physically and economically concerns that occur in cancers patients cannot be neglected. However, current diagnostic methods and cure duration do not fulfill patients requirements. Therefore, it is essential to detect and diagnose cancer biomarkers as soon as possible and overcome the current burdens. Novel aptasensors is emerging as one of the most promising strategies for early recognition of cancer. Aptamers an artificial DNA or RNA sequences, possess plenty of merits such as easy produc…
Dienas kārtības plānošanas lietotne
2018
Kvalifikācijas darba ietvaros tika izstrādāta lietotne ar dienas plānošanas kārtības tematiku. Darba autors ir Latvijas Universitātes students Antons Jelčins. Kvalifikācijas darba sistēma ir plānošanas kārtības lietotne, kurā lietotāji var ērti plānot pasākumus. Lietotne ļauj lietotājiem efektīvāk organizēt savu laiku, saglābāt nepieciešamo informāciju, atzīmēt svarīgus plānotus datumus un pievienot tos arī dienas gaitā. Kvalifikācijas darba automatizētajā sistēmā galvenais uzsvars tiek likts uz lietotāja dienas kārtošanas informācijas veidošanu, tāpēc sistēmas prioritāte ir reģistrēts lietotājs, kuram ir ievērojams iespēju pārākums pār nereģistrēto lietotāju, tādejādi motivējot lietotāju r…
