The response of Trissolcus basalis to footprint contact kairomones from Nezara viridula females is mediated by leaf epicuticular waxes.
2009
Chemical footprints left behind by true bugs are perceived as contact kairomones by scelionid egg parasitoids. Female wasps encountering a contaminated artificial substrate display a characteristic arrestment posture, holding the body motionless and antennating the surface. In the system Nezara viridula (L.) and its egg parasitoid Trissolcus basalis (Wollaston), previous studies have shown that the kairomone mediating such behavior is part of N. viridula's cuticular hydrocarbons (CHC) and furthermore that the wasp's ability to discriminate host male and female footprints is mainly based on the presence/absence of nonadecane (nC(19)). In this study, the effect of epicuticular waxes of leaves…
Visual dynamic environment for distributed systems
2002
Algorithms, based on information fusion, are often embodied in visual perception systems. Distributed architectures have been recently proposed to perform integrated computation. The complexity of distributed systems regards both their design, and the software environment to develop applications. Visual and iconic programming style intends to provide expressive tools to implement, to debug, and to execute programs in distributed environment. Multi-layers graphs languages seem suitable to handle such complexity. This paper describes the design of a visual dynamic environment (VDE), which is based on a graph-grammar. A new class of dynamic visual interfaces is also introduced, and its propert…
From abugida to alphabet in Konso, Ethiopia
2019
Abstract This study examines the interplay between phonological awareness and orthography in Konso, a Cushitic language in Southwest Ethiopia. Thirty-two adults reading the Konso abugida but with minimal exposure to alphabetic literacy completed an orally administered phoneme deletion task. The responses were then examined using the minimal edit distance hypothesis (Wali, Sproat, Padakannaya & Bhuvaneshwari, 2009) as a framework for the analysis. The results suggest that the difficulty of a deletion was related to the way the phoneme was represented in the Konso abugida. Content-based error analysis of the incorrect responses gave indications of how Konso abugida readers’ processing of …
Nabrzeżkowate (Heteroptera: Saldidae) Polski – przegląd faunistyczny / Shore bugs (Heteroptera: Saldidae) of Poland – a faunistic review
2022
This paper is a faunistic review of 23 species of the family Saldidae occurring in Poland. The study was based on the original papers relating to the territory of Poland and on materials deposited in several institutions, i.e. University of Opole (UO), Museum and Institute of Zoology, Polish Academy of Sciences, Warsaw (ZMPA), and in Nature Collections of the Faculty of Biology of Adam Mickiewicz University in Poznań (ZPUAM). Over 4000 specimens preserved at the institutions mentioned above have been examined, identified, or their previous identifications were verified. All the localities (with their UTM coordinates) for each of the 23 species occurring in Poland are listed in alphabetical …
Damsel bugs (Hemiptera:Heteroptera: Nabidae) of Poland: identification key, distribution and bionomy
2020
Rodzina Nabidae (zażartkowate) w Polsce reprezentowana jest 15 gatunków należących do dwóch podrodzin: Prostemmatinae i Nabinae. Pierwsza z nich obejmuje dwa gatunki należące do rodzaju Prostemma, Nabinae są reprezentowane przez 13 gatunków sklasyfikowanych w dwóch rodzajach: Himacerus i Nabis. Niniejsza praca podsumowuje rozmieszczenie zażartkowatych w Polsce na podstawie danych literaturowych oraz niepublikowanych. Zaprezentowano mapy rozmieszczenia każdego gatunku w Polsce i w Palearktyce. Ponadto przedstawiono dwujęzyczny klucz do identyfikacji zilustrowany wysokiej jakości fotografiami. Omówiono bionomię każdego gatunku. Analiza rozmieszczenia Nabidae w Polsce wskazuje na stosunkowo do…
MansOS
2010
Often software for wireless sensor networks (WSNs) is developed using a specific event based operating system (OS) such as TinyOS. However, this requires steep learning curve for the new developers. Other operating systems for embedded devices have limited support for new hardware platforms. Our goal is to provide an operating system for resource constrained devices that is easy to use for the wide range of researchers and developers familiar with C programming language and Unix operating system concepts. In addition, we provide a framework for agile portability to new hardware platforms, due to the nature of WSN systems that require specific hardware or features for the sensing tasks at ha…
Badania nad potencjalnym wykorzystaniem pluskwiaków różnoskrzydłych (Hemiptera: Heteroptera) w bioindykacji i monitoringu przyrodniczym
2023
This paper presented the results of the studies on true bugs (Hemiptera: Heteroptera) alongside evaluating their potential usefulness in biomonitoring and bioindication. The studies were carried out in May and August of 2017. Three research sites situated at various distances from the full-scale plants (Grupa Azoty Zakłady Azotowe Kędzierzyn SA, Zakłady Chemiczne Petrochemia-Blachownia SA, Zakłady Koksownicze ArcelorMittal Poland Zdzieszowice) and the control area out of reach of the emission of chemical pollutants, i.e. the meadows in the Chrząstowice area of Natura 2000, have been selected for studies. All studied meadows were classified within the Molinio-Arrhenatheretea class. As a resu…
Cytokines gene expression in the tunica albuginea in patients with Peyronie’s disease. Pilot study with a control group
2011
INTRODUCTION: We decided to conduct a study to investigate the presence of cytokines in the albuginea of subjects with Peyronie's disease (PD). Cytokines, as responsible for intercellular communication, maybe involved in the pathogenesis of the disease. The identification of one or more involved cytokines may, in fact, be useful in the pharmacological treatment with biologic drugs that are able to interfere with specific cytokines. MATERIALS AND METHODS: Between January 2009 and Decembre 2010 at the Clinic of Urological outpatients clinic of the Policlinico of Palermo were recruited 20 subjects with PD, mean age 62.3 years (range 51-70) and 8 subjects with congenital recurvatum penis (mean …
MR-Tomographie bei Hodenprozessen
1992
The value of T1-weighted sequences after intravenous administration of Gd-DTPA and of T2-weighted sequences was compared in 43 patients suspected of having scrotal abnormalities. T2-weighted sequences gave better demonstration of the tunica albuginea and better contrast between tumor and parenchyma. The two techniques were equally sensitive for demonstrating testicular tumors but orchitis was better demonstrated on the contrast enhanced sequences. Motion artifacts were less marked in the T1-weighted sequences with contrast enhancement. In selected cases, contrast enhancement may be a valuable addition to native protocols. Our experience has indicated that MRI provides specific findings in c…
The Comparison of Software Reliability Assessment Models
2015
Abstract The reliability of the software represents one of the most important attributes of software quality, and the estimation of the reliability of the software is a problem hard to solve with accuracy. Nevertheless, in order to manage the quality of the software and of the standard practices in an organization, it is important to achieve an estimation of the reliability as accurate as possible. In the present work there are described the principles and techniques which underlie the estimation of the reliability of the software, starting from the definition of the concepts which express the attributes of software quality. It is taken into account the issue of the estimation of a software…
