Phase-Sensitive Detection for Optical Sensing With Porous Silicon

2012

We report on a photonic sensor with an ultralow limit of detection (LoD) based on a phase interrogation readout scheme together with an anisotropic porous silicon (PSi) membrane. First, the fabrication of porous free-standing membranes from medium doped (100) surface oriented silicon, with pore diameters suitable for the infiltration of biomolecules, around 50 nm, is reported. Then, the phase interrogation scheme for characterizing the PSi membranes is presented whose results show that while volumetric sensitivity increases with the membrane thickness, the resolution in the birefringence measurements decrease dramatically due to depolarization effects. The best LoD was found to be equal to …

SNPs detection by eBWT positional clustering

2019

Sequencing technologies keep on turning cheaper and faster, thus putting a growing pressure for data structures designed to efficiently store raw data, and possibly perform analysis therein. In this view, there is a growing interest in alignment-free and reference-free variants calling methods that only make use of (suitably indexed) raw reads data. We develop the positional clustering theory that (i) describes how the extended Burrows–Wheeler Transform (eBWT) of a collection of reads tends to cluster together bases that cover the same genome position (ii) predicts the size of such clusters, and (iii) exhibits an elegant and precise LCP array based procedure to locate such clusters in the e…

Whistleblowing in the Context of Zimbabwe’s Economic Crisis

2007

Whistle blowing is a topic that has taken center stage in philosophical discussions on business ethics in recent years. It continues to provoke debate among academics because of its continued relevance to the present prevailing situations the world over. The recent upsurge in cases of corporate wrongdoings in Zimbabwe has seriously reactivated a concerted debate on the moral justification of whistle blowing. The whistle blower is, however, faced with competing and conflicting moral values and imperatives that make his decision to blow the whistle a morally excruciating endeavour. It is the contention of this article that, despite employees’ obligations of loyalty and obedience to their empl…

Precise Determination of the Unperturbed 8B Neutrino Spectrum

2012

The measurement was performed at the Kernfysisch Versneller Instituut (KVI) at the University of Groningen, The Netherlands.; A measurement of the final state distribution of the 8B $\beta$ decay, obtained by implanting a 8B beam in a double-sided silicon strip detector, is reported here. The present spectrum is consistent with a recent independent precise measurement performed by our collaboration at the IGISOL facility, Jyvâskylä [O. S. Kirsebom et al., Phys. Rev. C 83, 065802 (2011)]. It shows discrepancies with previously measured spectra, leading to differences in the derived neutrino spectrum. Thanks to a low detection threshold, the neutrino spectrum is for the first time directly ex…

Koleraepidemia Zimbabwessa : diskurssianalyysi The Heraldin ja Helsingin Sanomien uutisoinnista

2012

Tässä pro gradu -tutkimuksessa tarkastellaan zimbabwelaisen valtio-omisteisen sanomalehden The Heraldin ja Helsingin Sanomien uutisointia Zimbabwen koleraepidemiasta vuosina 2008-2009. Tutkimuksen tavoitteena on selvittää millaisin diskurssein eli äänenpainoin lehdet kertovat Zimbabwen tapahtumista. Kehitysmaajournalismia on tutkittu viime vuosina monesta näkökulmasta, mutta tutkimusta, jossa olisi vertailtu kehitysmaan ja länsimedian uutisointia, ei juurikaan ole tehty. Koska valtiolliset lehdet ovat tiukasti maiden hallitusten kontrollissa, on syytä kysyä millaisen kuvan ne antavat maansa tapahtumista. Saivatko zimbabwelaiset maassaan riehuvasta koleraepidemiasta erilaisen kuvan valtiolli…

Rapid detection and discrimination of fabaviruses by flow-through hybridisation with genus- and species-specific riboprobes

2015

Viruses cause significant damage in agricultural crops worldwide. Disease management requires sensitive and specific tools for virus detection and identification. Also, detection techniques need to be rapid to keep pace with the continuous emergence of new viral diseases. The genus Fabavirus is composed of five viruses infecting many economically important crops worldwide. This research describes the development of a procedure based on flow-through hybridisation (FTH), which is faster than and as sensitive as conventional hybridisation for virus detection in tissue-prints from infected plants. Six digoxigenin-labelled RNA probes were synthesised with two levels of specificity: (a) five spec…
