Formation and characterization of inorganic membranes from zeolite-silica microcomposites

Small crystals of zeolites (500-1000 nm) with two- and three-dimensional channel systems (faujasite and ZSM-5 structures) were embedded in amorphous thin films derived from TEOS hydrolyzed in alcoholic solution. Scanning electron microscopy studies show that the zeolites can be quite evenly dispersed in the membrane, resulting in single layers of zeolite crystals protruding out of the amorphous matrix. In situ FT-IR studies with a series of probe molecules revealed that in most membranes the zeolites were 100% accessible from the gas phase. The membranes excluded molecules which are larger than the pore openings of the zeolite embedded in the composite

An entrancing tale of cross-disciplinary bridge building and burning in ethnopsychophysiomusicology

Having a paper accepted for publication is challenging, even under the best of circumstances, as when reporting an incremental finding in a field that is one’s home discipline. The process becomes considerably more difficult when venturing into foreign disciplines in which methodological conventions and assumptions may differ from those one is familiar with. Provocative topics may further exacerbate the reticence of reviewers and editors to welcome cross-disciplinary research to a journal’s pages. Here, a pair of papers, one of which describes a study of possible physiological correlates of music- induced trance states, and the other which describes the challenging journey to get the research performed and published, provide a case study for examining whether epistemological divides can be bridged in the face of editorial obstinacy

Commentary on "The Processing of Pitch and Scale: An ERP Study of Musicians Trained Outside of the Western Musical System" by Bischoff Renninger, Wilson, and Donchin

Electrophysiological measures of expectancy violation processing by the brain, such as the P300 component of the event-related potential, have provided insight into the way in which humans with varying amounts of musical experience maintain representations of musical information, in particular tonal representations. Bischoff Renninger and colleagues (2006) seek to extend this work by examining the P300 in the context of the very interesting topic of cross-cultural music perception, using Western listeners who either have or have not undergone training in Javanese music. Their study highlights the myriad issues and complexities of experimental design and analysis that must be addressed if one is to conduct an ethologically compelling and interpretable study of musical context representations using brain responses as dependent measures

Status quo and development trends of remote sensing usage for forensic ekotechnique: forest and trees

This paper refers to possibility of Unmanned Aerial Vehicle (UAV) usage for FEFT experts’ needs. Different Remote Sensing Stations (Czech Geological Survey, Forest Management Institute and others) obtain Czech territory actual pictorial data from satellites together with aerial images, LiDaR data from Ministry of Agriculture, Ministry of Defense and Czech Office for Surveying Mapping and Cadastre (COSMC) joint project that deals with regular two years scanning of the Czech Republic. Remote Sensing Stations also have resources for obtaining actual aerial photographs of investigated objects and localities through commercial subjects operating own airplanes. State organizations initiating expertise do not have resources for actual scanning of the investigated localities with airplanes. Forensic experts depend on COSMC products. COSMC is the only one of the organizations dealing with Czech territory scanning which has authority to sell actual aerial images if are available. Remote-controlled UAVs can aboard equipment for remote sensing. UAVs service expenses are many-times lower than aircraft service expenses. Department of Geoinformation Technologies at Mendel University Brno has a multirotor UAV available that is equipped to gain optical and infrared band data.Tématem tohoto příspěvku je poukázat na možnosti využití bezpilotních letounů (UAV - Unmanned Aerial Vehicle) pro potřeby soudních znalců pracujících v oboru FEld. Různá pracoviště DPZ (Česká geologická služba, ÚHÚL a jiná) získávají aktuální obrazová data našeho území z družic a současně mohou pracovat i s leteckými snímky a lidarovými daty získanými ze společného projektu Ministerstva zemědělství, Ministerstva obrany a Českého zeměměřičského ústavu (ČÚZK) v rámci kterého se provádí pravidelné snímkování (skenování) České republiky nyní v dvouletých cyklech. Případně mají tato pracoviště DPZ k dispozici dostatek finančních prostředků na zaplacení subjektu s letovým parkem, který nafotografuje vyžádané objekty a dodá aktuální obrazová data. Prostředí iniciující zadávání znaleckých posudků nedisponuje dostatečnými finančními prostředky k zajištění zhotovení leteckých snímků zkoumaných lokalit či objektů klasickými metodami za použití letounů. Soudní znalci jsou tudíž odkázáni na ČÚZK, který jediný ze zapojených subjektů do projektu snímkování ČR je oprávněn poskytovat aktuální data, jsou-li tato k dispozici. Dálkově ovládané bezpilotní letouny mohou mimo jiné sloužit jako nosiče přístrojů snímající zemský povrch. Provozní a finanční nároky jsou však mnohonásobně nižší v porovnání s klasickými letouny. Ústav geoinformačních technologií Mendelovy univerzity v Brně disponuje multirotorovým bezpilotním letounem, který je přizpůsoben k získávání dat DPZ ve viditelném a blízkém infračerveném elektromagnetickém spektru

Analysing powers for the reaction n⃗p→ppπ−\vec{\rm n} {\rm p} \to {\rm p} {\rm p} \pi^{-} and for np elastic scattering from 270 to 570 MeV

The analysing power of the reaction ${\rm n}{\rm p} \to {\rm p}{\rm p} \pi^{-}$ for neutron energies between threshold and 570 MeV has been determined using a transversely polarised neutron beam at PSI. The reaction has been studied in a kinematically complete measurement using a time-of-flight spectrometer with large acceptance. Analysing powers have been determined as a function of the c.m. pion angle in different regions of the proton-proton invariant mass. They are compared to other data from the reactions ${\rm n}{\rm p} \to {\rm p}{\rm p} \pi^{-}$ and ${{\rm p}{\rm p} \to {\rm p}{\rm p} \pi^{0}}$. The np elastic scattering analysing power was determined as a by-product of the measurements.Comment: 12 pages, 6 figures, subitted to EPJ-

The reaction np→ppπ−{n} {p} \to {p} {p} \pi^{-} from threshold up to 570 MeV

The reaction ${n} {p} \to {p} {p} \pi^{-}$ has been studied in a kinematically complete measurement with a large acceptance time-of-flight spectrometer for incident neutron energies between threshold and 570 MeV. The proton-proton invariant mass distributions show a strong enhancement due to the pp($^{1}{S}_{0}$) final state interaction. A large anisotropy was found in the pion angular distributions in contrast to the reaction ${p}{p} \to {p}{p} \pi^{0}$. At small energies, a large forward/backward asymmetry has been observed. From the measured integrated cross section $\sigma({n}{p} \to {\rm p}{p} \pi^{-})$, the isoscalar cross section $\sigma_{01}$ has been extracted. Its energy dependence indicates that mainly partial waves with Sp final states contribute. Note: Due to a coding error, the differential cross sections ${d \sigma}/{d M_{pp}}$ as shown in Fig. 9 are too small by a factor of two, and inn Table 3 the differential cross sections ${d \sigma}/{d \Omega_{\pi}^{*}}$ are too large by a factor of $10/2\pi$. The integrated cross sections and all conclusions remain unchanged. A corresponding erratum has been submitted and accepted by European Physics Journal.Comment: 18 pages, 16 figure

Inkjet printed LED based pH chemical sensor for gas sensing

Predictable behaviour is a critical factor when developing a sensor for potential deployment within a wireless sensor network (WSN). The work presented here details the fabrication and performance of an optical chemical sensor for gaseous acetic acid analysis, which was constructed using inkjet printed deposition of a colorimetric chemical sensor. The chemical sensor comprised a pH indicator dye (bromophenol blue), phase transfer salt tetrahexylammonium bromide and polymer ethyl cellulose dissolved in 1-butanol. A paired emitter-detector diode (PEDD) optical detector was employed to monitor responses of the colorimetric chemical sensor as it exhibits good sensitivity, low power consumption, is low cost, accurate and has excellent signal to noise ratios. The chemical sensor formulation was printed directly onto the surface the emitter LED, and the resulting chemical sensors characterised with respect to their layer thickness, response time and recovery time. The fabrication reproducibility of inkjet printed chemical sensors in comparison to drop casted chemical sensors was investigated. Colorimetric chemical sensors produced by inkjet printing, exhibited an improved reproducibility for the detection of gaseous acetic acid with a relative standard deviation of 5.5 % in comparison to 68.0 % calculated for drop casted sensors (n = 10). The stability of the chemical sensor was also investigated through both intra and inter-day studies
