Iodine(I) and Silver(I) Complexes Incorporating 3-Substituted Pyridines

2023

Building upon the first report of a 3-acetaminopyridine-based iodine(I) complex (1b) and its unexpected reactivity toward tBuOMe, several new 3-substituted iodine(I) complexes (2b–5b) have been synthesized. The iodine(I) complexes were synthesized from their analogous silver(I) complexes (2a–5a) via a silver(I) to iodine(I) cation exchange reaction, incorporating functionally related substituents as 3-acetaminopyridine in 1b; 3-acetylpyridine (3-Acpy; 2), 3-aminopyridine (3-NH2py; 3), and 3-dimethylaminopyridine (3-NMe2py; 4), as well as the strongly electron-withdrawing 3-cyanopyridine (3-CNpy; 5), to probe the possible limitations of iodine(I) complex formation. The individual properties …

Zastosowanie metody TDABC do szacowania kosztów działań informacyjnych pośredników w obrocie nieruchomościami

2016

W niniejszej pracy do szacowania kosztów działań informacyjnych pośredników w obrocie nieruchomościami wykorzystano metodę TDABC. W celu przedstawienia i analizy działań informacyjnych posłużono się algorytmem w postaci schematu blokowego. W algorytmie tym zawarto charakterystykę zmiennych (tzw. nośników działań) oraz opisy działań informacyjnych realizowanych przez pośredników. Poszczególne opisy wzbogacono o zmienne mające bezpośredni wpływ na czas ich realizacji, a także średnie czasy ich wykonania. Czasy realizacji oszacowano na podstawie badań eksperymentalnych i ankietowych. Opracowane ogólne równanie czasowe dla dowolnego przebiegu procesu wynikającego z realizowanych czynności pośre…

This study examines parents’ experiences of the assessment and its outcomes in child welfare. The research question is as follows: What factors concerning the assessment process and context contribute to the outcomes of the assessment from the perspective of the parents? The realistic evaluation and program theory research give an evaluation research framework to the study. In the study 177 parents from seven municipalities who are clients of child welfare participated. Their families had experienced the assessment in child welfare. Various analysis methods were used: cross table, t-test, correlation, fac- tor analysis, hierarchical regression analysis, two-way variance analysis and the boo…

Una poetica per frammenti

2015

L’articolo offre una recensione del libro di Sergio Polano, Carlo Scarpa: Palazzo Abatellis, (Electa, Milano 1996). Il volume, corredato di illustrazioni e documenti inediti, racconta della strategia delle sequenze edificate da Scarpa (Venezia 1906 - Sendai 1978) nel 1953, quando viene incaricato da Giorgio Vigni del recupero di palazzo Abatellis a Palermo, un prestigioso edificio dell’ultimo decennio del Quattrocento.All’interno del volume altri saggi ricostruiscono tutti gli aspetti dell’opera scarpiana in palazzo Abatellis e offrono anche la possibilità di consultare facilmente quanto conservato negli archivi. I risultati di questa ricerca, curata da Polano per Electa, confermano l’impor…

Land-use changes in an agro-pastoral area (Djougou, Benin) from Landsat archive images (1984 and 2012): a regressive approach combining remote sensin…

2018

Extended abstract:The vegetation of the district of Djougou is affected by large changes due to tree logging, crop field clearing and grazing by increasing numbers of livestock. The dynamics of the landscape is analyzed with a time series of Landsat satellite images (1984-2012). A regressive approach, exploiting the field observations and semi-structured interviews conducted in 2012-2013 in the Bakou-Wewe territory, documents the evolution of land use and facilitates the analysis of Landsat images. An original procedure targets the building of Region of interest (ROIs) for the historic images for which no available field observations exists. The study area is located in central Benin (Plate…

Rotational effects on the oscillation frequencies of newly born proto-neutron stars

2003

In this paper we study the effects of rotation on the frequencies of the quasi-normal modes of a proto-neutron star (PNS) born in a gravitational collapse during the first minute of life. Our analysis starts a few tenths of seconds after the PNS formation, when the stellar evolution can be described by a sequence of equilibrium configurations. We use the evolutionary models developed by Pons et al. (1999; 2001) that describe how a non rotating star cools down and contracts while neutrino diffusion and thermalization processes dominate the stellar dynamics. For assigned values of the evolution time, we set the star into slow rotation and integrate the equations of stellar perturbations in th…

Gap Filling of Biophysical Parameter Time Series with Multi-Output Gaussian Processes

2018

In this work we evaluate multi-output (MO) Gaussian Process (GP) models based on the linear model of coregionalization (LMC) for estimation of biophysical parameter variables under a gap filling setup. In particular, we focus on LAI and fAPAR over rice areas. We show how this problem cannot be solved with standard single-output (SO) GP models, and how the proposed MO-GP models are able to successfully predict these variables even in high missing data regimes, by implicitly performing an across-domain information transfer.

The impact of in-canopy wind profile formulations on heat flux estimation using the remote sensing-based two-source model for an open orchard canopy …

2010

Abstract. For open orchard and vineyard canopies containing significant fractions of exposed soil (>50%), typical of Mediterranean agricultural regions, the energy balance of the vegetation elements is strongly influenced by heat exchange with the bare soil/substrate. For these agricultural systems a "two-source" approach, where radiation and turbulent exchange between the soil and canopy elements are explicitly modelled, appears to be the only suitable methodology for reliably assessing energy fluxes. In strongly clumped canopies, the effective wind speed profile inside and below the canopy layer can highly influence the partitioning of energy fluxes between the soil and vegetation comp…

Fault diagnosis of induction motors broken rotor bars by pattern recognition based on noise cancelation

2014

Current signal monitoring (CSM) can be used as an effective tool for diagnosing broken rotor bars fault in induction motors. In this paper, fault diagnosis and classification based on artificial neural networks (ANNs) is done in two stages. In the first stage, a filter is designed to remove irrelevant fault components (such as noise) of current signals. The coefficients of the filter are obtained by least square (LS) algorithm. Then by extracting suitable time domain features from filter's output, a neural network is trained for fault classification. The output vector of this network is represented in one of four categories that includes healthy mode, a 5 mm crack on a bar, one broken bar, …
