Configurable low-cost plotter device for fabrication of multi-color sub-cellular scale microarrays.
2014
We report on the construction and operation of a low-cost plotter for fabrication of microarrays for multiplexed single-cell analyses. The printing head consists of polymeric pyramidal pens mounted on a rotation stage installed on an aluminium frame. This construction enables printing of microarrays onto glass substrates mounted on a tilt stage, controlled by a Lab-View operated user interface. The plotter can be assembled by typical academic workshops from components of less than 15 000 Euro. The functionality of the instrument is demonstrated by printing DNA microarrays on the area of 0.5 squared centimeters using up to three different oligonucleotides. Typical feature sizes are 5 μm diam…
Sižeta struktūra Dž. K. Roulingas romānā “Harijs Poters un Jauktasiņu princis”
2016
Bakalaura darbā veikta Dž. K. Roulingas romāna “Harijs Poters un Jauktasiņu Princis” sižeta struktūras analīze. Tā mērķis ir analizēt romāna “Harijs Poters un Jauktasiņu Princis” struktūras atbilstību Freitāga piramīdai. Pētījumā apskatīts katrs Freitāga piramīdas posms un analizēts Roulingas romāns, pielietojot Freitāga piramīdu. Darbā arī aprakstīti sarežģījumi, peripetijas, atpazīšanas skati un ciešanas, kā arī analizēta tēlu izvēļu nozīme sižeta attīstībai. Lai sasniegtu pētījuma mērķi, veikta literārā darba analīze, interpretācija un strukturālā analīze. Pētījums pierāda, ka romāna “Harijs Poters un Jauktasiņu Princis” struktūra atbilst Freitāga piramīdai, kas papildināta ar sarežģījum…
An innovative multi-analytical approach based on spectroscopic and electrochemical techniques to study a complex Roman amphorae collection
2020
Abstract An innovative multi-analytical approach for the classification of ancient pottery sherds was tested. Twenty Roman amphorae fragments belonging to different known typologies and twenty-seven unclassified ones from a complex Sagunto Archaeological Museum (Spain) collection were studied by multielement analysis (X-ray fluorescence spectroscopy and inductively coupled plasma mass spectrometry), Fourier-transform near infrared spectroscopy and voltammetry of immobilized microparticles employing a minimal amount of sample. Chemometric analysis based on principal component analysis allowed the identification of most of the unclassified samples, proving the importance and reliability of th…
Intrasite Artefact Survey at Terravecchia di Cuti (Sicily)
2016
In this paper, we discuss the results of an artefact survey and a sampling collection in the indigenous settlement of Terravecchia di Cuti, in the chora of the Greek colony of Himera (Sicily). The whole area of the town was gridded with squares of 10x10 m to isolate functional areas and identify the most interesting zones for new archaeological samples. The survey was carried out in two fields (9400 m2), counting and recording all findings. Only diagnostic pottery and figured pottery, antefixes, loom weights, millstones and so on were collected. We can observe, analysing in detail our results for both fields, that functional areas could not be isolated, perhaps because the urban and social …
When does Regression discontinuity design work? Evidence from random election outcomes
2018
We use elections data in which a large number of ties in vote counts between candidates are resolved via a lottery to study the personal incumbency advantage. We benchmark non‐experimental regression discontinuity design (RDD) estimates against the estimate produced by this experiment that takes place exactly at the cutoff. The experimental estimate suggests that there is no personal incumbency advantage. In contrast, conventional local polynomial RDD estimates suggest a moderate and statistically significant effect. Bias‐corrected RDD estimates that apply robust inference are, however, in line with the experimental estimate. Therefore, state‐of‐the‐art implementation of RDD can meet the re…
SEM–EDS ANALYSIS AS A RAPID TOOL FOR DISTINGUISHING CAMPANIAN A WARE AND SICILIAN IMITATIONS
2013
The aim of this work is to examine whether it is possible to find chemical markers that allow a distinction to be made between the imported black glossed ‘Campanian A’ and the Sicilian imitation (end of fourth to first century BC) of these productions by carrying out quantitative chemical microanalysis of the slip using the SEM–EDS technique. The efficiency of the proposed analytical method has been tested on a set of ceramic samples corresponding to Sicilian black gloss imitations whose ceramic body has already been characterized petrographically by thin-section microscopy and chemically by XRF. The analytical data point to Na2O as a suitable chemical marker to distinguish between original…
Budgeting soil erosion from floodplain sediments of the central Rhenish Slate Mountains (Westerwald), Germany
2011
The distribution, thickness and composition of the floodplain sediments in the valleys of the Gelbach (Lower Westerwald) and Große Nister (Upper Westerwald) depend on the occurrence of loessic periglacial cover beds in their catchments as well as on historical land use. The budget of floodplain sedimentation was derived from a study of the floodloams underlying the monastery garden of Marienstatt, a village in the Große Nister valley. From the study of two occupation levels, pottery shards and radiocarbon dating, 55% of the floodloam can be attributed to the Modern period (younger than c. AD 1450). From the radiocarbon age of a charcoal fragment extracted from the base of the floodloam at …
Integrated prototyping and rendering system for the display of ceramic finds
2017
The project, carried out in collaboration between the Department of Architecture of Palermo and the Archaeological Museum Antonino Salinas of Palermo, proposes a system of integration and reconstruction of ceramic artefacts, using modeling, 3D printing and rendering processes for an integrated museum exhibition system, which the viewers can observe the fragment nearing the re-reconstructed fragment that reconstructs the original morphology and an interactive digital model in which the viewers can also observe the metric aspect and, where present, the decorative apparatus.
Loeb Classical Library, Hippocrates, volume X, Edited and Translated by P. Potter.
2015
Il X volume di Hippocrates della Loeb Classical Library contiene l'edizione con traduzione inglese a fronte di alcuni importanti scritti ippocratici a cura d Paul Potter, uno dei più autorevoli esperti internazionali in materia di edizione e interpretazione di scritti medici. Oltre all'edizione del de genitura/de natura pueri e del IV libro del de morbis ippocratico, viene proposto per la prima volta dai tempi di E. Littré il testo del de sterilibus, il volume si completa con una nuova edizione del de natura muliebri. La recensione passa in rassegna le scelte dell'editore, il metodo di selezione dei testimoni, la questione delle relazioni tra gli scritti, nonché questioni di lessicografia e…
