Setting a social reform agenda : the peacebuilding dimension of the Rights Movement of the Ethiopian muslims diaspora
2011
Introduction: This working paper examines the impact of the Ethiopian Muslims in the diaspora on socio-political processes in the homeland, with a special focus on their activities that have a bearing on peace-building. Within the DIASPEACE the research project falls within Working Package 3 (WP3) that focuses on the economic, social and political remittances of the diaspora from the Horn of Africa in Europe to their respective homelands. Ethiopia has one of the largest diaspora populations in the world. The exact number of the Ethiopian diaspora is not yet known, but it is widely believed that over half a million Ethiopians live in North America and Europe (Lyons 2006). The Ethiopian diasp…
Immuno-MALDI-MS in Human Plasma and on-Chip Biomarker Characterizations at the Femtomole Level
2012
Immuno-SPR-MS is the combination of immuno-sensors in biochip format with mass spectrometry. This association of instrumentation allows the detection and the quantification of proteins of interest by SPR and their molecular characterization by additional MS analysis. However, two major bottlenecks must be overcome for a wide diffusion of the SPR-MS analytical platform: (i) To warrant all the potentialities of MS, an enzymatic digestion step must be developed taking into account the spot formats on the biochip and (ii) the biological relevancy of such an analytical solution requires that biosensing must be performed in complex media. In this study, we developed a procedure for the detection …
Oblio e memoria del reato nel sistema penale
2022
La prescrizione del reato è istituto penalistico straordinariamente complesso e di indubbio rilievo strategico per l’equilibrio del sistema penale. Il nesso indissolubile con le funzioni della pena ed il regime giuridico di tipo oggettivo, improntato a sostanziale automatismo ne rivelano il reale significato di elemento strutturale della repressione penale, indispensabile per assicurare la conformità delle dinamiche punitive al naturale decorso delle cose e della vita. Più che una fattispecie di mera non-punibilità sopravvenuta, la prescrizione del reato costituisce dunque una condizione essenziale in negativo per l’applicazione delle norme incriminatrici di parte speciale, per ognuna delle…

The arsenic content of human semen.
2009
Arsenic concentration was measured by atomic absorption spectrometer in ejaculates of 13 subfertile men, 6 control individuals and pool-ejaculate of 24 further andrological patients. While the detection limit was 1 microgram/l, arsenic concentration amounted to 2 micrograms AS/l in ejaculates. In the cellular fractions of seminal fluid, concentration of arsenic was under the detection limit. Arsenic concentration of smokers and non-smokers did not differ.
Determination of selenium, zinc and cadmium in antidandruff shampoos by atomic spectrometry after microwave assisted sample digestion
2000
Microwave assisted pre-treatments for atomic spectrometric determination (inductive coupled plasma-optical emission spectrometry, ICP-OES or flame atomic absorption spectrometry, FAAS) of metallic elements, usually present in antidandruff shampoos, are proposed. They are based on the digestion of the sample with HNO(3) into a closed reactor, which is irradiated at 800 W for a few minutes. Selenium was determined by ICP-OES. The limit of detection was 0.11 mg l(-1); the relative standard deviation (R.S.D.) for the selenium content in the samples was in the 0.6-3.6% range. The results obtained were in agreement with the label contents and the recovery of the proposed method was in the 100-106…
Electrothermal Atomic Absorption Determination of Chromium in Sediments
1999
Abstract An electrothermal atomic absorption spectrometric method has been developed to determine total chromium concentration in natural sediment samples. Samples were mineralized by dry ashing at 550°C and fused at 1100°C for 30 min with lithium metaborate. Dissolved samples were injected in graphite tubes, mineralized at 1100°C, and atomized at 2600°C. Standard addition calibration made unnecessary the use of chemical modifiers. The method provided a limit of detection from 23 to 45 ng liter −1 . The relative standard deviation for chromium determination was between 3 and 14%. Results obtained for a standard reference material agree well with the certified value. A series of natural samp…
A new simple chromo-fluorogenic probe for NO2 detection in air.
2015
[EN] A new chromo-fluorogenic probe, consisting of a biphenyl derivative containing both a silylbenzyl ether and a N,N-dimethylamino group, for NO2 detection in the gas phase has been developed. A clear colour change from colourless to yellow together with an emission quenching was observed when the probe reacted with NO2. A limit of detection to the naked eye of about 0.1 ppm was determined and the system was successfully applied to the detection of NO2 in realistic atmospheric conditions.
Granice wiedzy o literaturze. Słowo o kilku nowych ujęciach interdyscyplinarności (z dodatkiem jednego przykładu)
2015
The paper consists of the review of a number of academic approaches to interdisciplinary research as represented by the Polish theorists of literature (Andrzej Hejmej, Michał P. Markowski, Ryszard Nycz). On the example taken from Tadeusz Nowak’s novel A jak królem, a jak katem będziesz, the author attempts to identify the nature of the close relations between anthropological and literary discourses, where the border line between them lies, and, consequently, what benefits for literary studies stem from anthropological readings.
