Comparison between a detailed and a simplified integrated model for the assessment of urban drainage environmental impact on an ephemeral river
2008
The benefit of integrated analysis has been demonstrated in technical literature and it is also required by the EU Water Framework Directive 60/2000, which proposes a water-quality-orientated view of the whole urban drainage system and oversees new ways of assessing its performance. Integrated models, such as any complex modelling approach, often have prohibitive data availability requirements that reduce their applicability. Moreover, widely different approaches can be applied, ranging from simple conceptual models to complex physically based ones. In the present paper, two approaches have been compared using data from an experimental catchment in Bologna ( Italy), which consists of a part…
MEASURING REGIONAL CONVERGENCE - AN APPLICATION TO THE EUROPEAN UNION AND ROMANIA
2012
Attention of regional economic convergence has a great place in economics literature. The application of spatially explicit methods of data analysis to the convergence question has yielded important insights on regional economic growth. The literature on regional income inequality, although somewhat older than the convergence literature, has been slower to adopt new spatially explicit methods of data analysis. Application of recently developed methods of spatial econometrics to the question of regional convergence has yielded a more comprehensive and multidimensional view of regional economic growth. This article aims to identify the techniques and methods use for regional convergence and i…
Paikannus piha-alueella kahta tai useampaa kameraa käyttäen
2018
Tässä tutkielmassa tarkastellaan web-kameroiden avulla toteutettavaa kohteen tunnistamista ja paikantamista. Työssä esitetään laskentakaavat ja menetel- mä, joita tarvitaan sijainnin määrittämiseen kahta tai useampaa kameraa käyttäen toteutettavassa paikantamisessa. Tuloksena havaitaan, että on mahdollista toteuttaa riittävään, noin 10 cm tarkkuuteen kykenevä, rajatulla piha-alueella itsenäisesti toi- mivien pienlaitteiden, kuten ruohonleikurin tai lumilingon, paikannusjärjestelmä HD- tai UHD-tasoisten web- tai usb-kameroiden avulla. The aim of this study is to find out possibility to use two or more webcams to positioning and identifying the target. In this study is presented math formu- l…
The effect of the genetic background on phage infectivity in an encapsulated host
2023
Los bacteriófagos desempeñan un papel clave en la ecología y evolución bacterianas y son potenciales antimicrobianos. Sin embargo, los factores determinantes de la especificidad fago-hospedador siguen siendo poco conocidos. Debido a la prevalencia de bacterias encapsuladas, la cápsula es la primera barrera que encuentran muchos fagos. Esta capa, normalmente de polisacáridos, puede bloquear el acceso de los fagos a los receptores de su pared celular. Para superarla, algunos fagos codifican dominios depolimerasa (Dpos) específicos en sus proteínas de unión a receptores. En este trabajo, hemos cuantificado la predictibilidad de las interacciones fago-bacteria basándonos en el tipo de locus cap…
Rapid Quantification of Microalgae Growth with Hyperspectral Camera and Vegetation Indices
2021
Spectral cameras are traditionally used in remote sensing of microalgae, but increasingly also in laboratory-scale applications, to study and monitor algae biomass in cultures. Practical and cost-efficient protocols for collecting and analyzing hyperspectral data are currently needed. The purpose of this study was to test a commercial, easy-to-use hyperspectral camera to monitor the growth of different algae strains in liquid samples. Indices calculated from wavebands from transmission imaging were compared against algae abundance and wet biomass obtained from an electronic cell counter, chlorophyll a concentration, and chlorophyll fluorescence. A ratio of selected wavebands containing near…

Clinical significance of the polymerase chain reaction (PCR) assay in chronic HBV carriers
1992
PCR was evaluated as a clinical tool for use in accurate identification of the specific etiologic agent in chronic HBV carriers. The method was found to be valuable in diagnosis and for monitoring therapy, as well as for elucidation of genotypic variants of HBV in chronic HBV cases. By this means an HBV defective variant with alterations in the preSl/preS2 sequence was detected and is consequently described here.
BIFOCAL PAIRS OF IMAGES FOR LOW-COST SURVEY IN CLOSE RANGE PHOTOGRAMMETRY
2019
Abstract. This paper present a method for close range photogrammetry based on an camera positioning scheme in which two cameras capture an equal portion of an object at the same scale, but have different focal lengths and camera-to-object distances. This scheme is alternative to the stereoscopic scheme and is associated with a system of equations which permits one to calculate first the relief displacement of points on a photograph and then their relief relative to a reference plane. The obtained relief and relief displacement values can be used to produce low-cost orthophotographs by using software for image processing, which doesn’t need to be dedicated, but has to provide measurement and…
SMART SfM: SALINAS ARCHAEOLOGICAL MUSEUM
2017
Abstract. In these last years, there has been an increasing use of the Structure from Motion (SfM) techniques applied to Cultural Heritage. The accessibility of SfM software can be especially advantageous to users in non-technical fields or to those with limited resources. Thanks to SfM using, everyone can make with a digital camera a 3D model applied to an object of both Cultural Heritage, and physically Environment, and work arts, etc. One very interesting and useful application can be envisioned into museum collection digitalization. In the last years, a social experiment has been conducted involving young generation to live a social museum using their own camera to take pictures and vid…
