Infinite lie groups of point transformations leaving invariant the linear equation which describes in the hodograph plane the isentropic one-dimensio…
1991
Abstract The group analysis of the hodograph equation which is equivalent to the non-linear system of one-dimensional isentropic gas dynamics reveals the existence of infinite groups of symmetry in correspondence with particular pressure laws. These turn out to be polytropes with selected indices, as is expected, as well as a new type of pressure. In all these cases the hodograph equation can be transformed, by a suitable change of variables, into the wave equationψ ζ = 0.
ChemInform Abstract: Synthesis and in vitro Studies on a Potential Dopamine Prodrug.
2009
Dopamine delivery to the central nervous system (CNS) undergoes the permeability limitations of blood-brain barrier (BBB) which is a selective interface that excludes most water-soluble molecules from entering the brain. Neutral amino acids permeate the BBB by specific transport systems. Condensation of dopamine with neutral amino acids could afford potential prodrugs able to interact with the BBB endogenous transporters and easily enter the brain. The synthesis and characterization of the dopamine derivative 2-amino-N-[2-(3,4-dihydroxy-phenyl)-ethyl]-3-phenyl-propionamide (7) is described. The chemical and enzymatic stability of 7 was evaluated. The molecular weight (300 Da) and Log Papp (…
Barthowskie spekulacje angelologiczne w "Die kirchliche Dogmatik" w świetle katolickich wypowiedzi dogmatycznych o aniołach
2015
Zasadniczą problematyką artykułu jest analiza wykładni angelologicznej dokonana przez Karla Bartha w jego monumentalnym dziele Dogmatyka kościelna i porównanie jej z katolicką ortodoksją Urzędu Nauczycielskiego Kościoła. Celem jest obrona tezy, że nauka o aniołach – tylko o tych, które nie upadły – zarysowana przez kontrowersyjnego, ale też znaczącego protestanckiego teologa, w żadnym wypadku nie musi stać w sprzeczności z powściągliwymi i mało precyzyjnymi stwierdzeniami odnośnie do istot anielskich, które przez Kościół rzymskokatolicki uznane zostały za wypowiedzi dogmatyczne. W pierwszej części artykułu został przedstawiony historyczny rozwój angelologii w oparciu o retrospektywne interp…

Gene regulatory networks elucidating Huanglongbing disease mechanisms
2013
Next-generation sequencing was exploited to gain deeper insight into the response to infection by Candidatus liberibacter asiaticus (CaLas), especially the immune disregulation and metabolic dysfunction caused by source-sink disruption. Previous fruit transcriptome data were compared with additional RNA-Seq data in three tissues: immature fruit, and young and mature leaves. Four categories of orchard trees were studied: symptomatic, asymptomatic, apparently healthy, and healthy. Principal component analysis found distinct expression patterns between immature and mature fruits and leaf samples for all four categories of trees. A predicted protein - protein interaction network identified HLB-…
Transcriptome profiling of citrus fruit response to huanglongbing disease.
2010
Huanglongbing (HLB) or "citrus greening" is the most destructive citrus disease worldwide. In this work, we studied host responses of citrus to infection with Candidatus Liberibacter asiaticus (CaLas) using next-generation sequencing technologies. A deep mRNA profile was obtained from peel of healthy and HLB- affected fruit. It was followed by pathway and protein-protein network analysis and quantitative real time PCR analysis of highly regulated genes. We identified differentially regulated pathways and constructed networks that provide a deep insight into the metabolism of affected fruit. Data mining revealed that HLB enhanced transcription of genes involved in the light reactions of phot…
BARGAINING WITH COMMITMENT UNDER AN UNCERTAIN DEADLINE
2006
We consider an infinite horizon bargaining game in which a deadline can arise with positive probability and where players possess an endogenous commitment device. We show that for any truncation of the game, the equilibrium agreement can only take place if the deadline arises within this finite horizon. Since the deadline is an uncertain event, the equilibrium exhibits agreements which are delayed with positive probability.
Agility activities for children in a municipality in Norway.
2015
The aim of this study was to investigate whether agility activity with dogs can be used to motivate less active children in physical activity and how such activity is experienced by parents and handlers. Data were collected through qualitative interviews with handlers and parents of the participating children. Agility with dogs appeared to motivate less active children to participate in, and endure, demanding physical activity. Joy and bonding with the dog appeared to be key elements in the motivational process. Motivation, initiation, and sustainment of activity over time are beneficial for children.
Factors Behind Junk DNA in Bacteria
2012
Although bacterial genomes have been traditionally viewed as being very compact, with relatively low amounts of repetitive and non-coding DNA, this view has dramatically changed in recent years. The increase of available complete bacterial genomes has revealed that many species present abundant repetitive DNA (i.e., insertion sequences, prophages or paralogous genes) and that many of these sequences are not functional but can have evolutionary consequences as concerns the adaptation to specialized host-related ecological niches. Comparative genomics analyses with close relatives that live in non-specialized environments reveal the nature and fate of this bacterial junk DNA. In addition, the…
Fault Injection into VHDL Models: Experimental Validation of a Fault-Tolerant Microcomputer System
1999
This work presents a campaign of fault injection to validate the dependability of a fault tolerant microcomputer system. The system is duplex with cold stand-by sparing, parity detection and a watchdog timer. The faults have been injected on a chip-level VHDL model, using an injection tool designed with this purpose. We have carried out a set of injection experiments (with 3000 injections each), injecting transient and permanent faults of types stuck-at, open-line and indetermination on both the signals and variables of the system, running a workload. We have analysed the pathology of the propagated errors, measured their latency, and calculated both detection and recovery coverage. We have…
