Late Valanginian (Early Cretaceous) lamellaptychi of the genus Mortilletilamellaptychus were collected from seven ammonite-controlled sections in south-eastern France demonstrate distinct changes in ribbing during growth. Simpler juvenile ribbing, which is essentially uniform for all of the specimens studied, differs distinctly from the complicated arrangement of the adult ribs. Changes in ribbing morphology were observed in the five species studied, two of which were identified as new (i.e. Mortilletilamellaptychus heterocostatus sp. nov. and M. bicostatus sp. nov.).

Late Berriasian–earliest Valanginian lamellaptychi (Cephalopoda) are described in detail for the first time. With one exception, all species belong to early representatives of Mortilletilamellaptychus. The majority of the well dated aptychi come from the cephalopod-rich sediments of the Vocontian Basin in south-eastern France; others are from south-eastern Spain. Thorolamellaptychus anglesensis sp. nov. is introduced.

Content available remote Synthesis of Reo Connectors for Strategies and Controllers
EN
In controller synthesis, i.e., the question whether there is a controller or strategy to achieve some objective in a given system, the controller is often realized as some kind of automaton. In the context of the exogenous coordination language Reo, where the coordination glue code between the components is realized as a network of channels, it is desirable for such synthesized controllers to also take the form of a Reo connector built from a repertoire of basic channels. In this paper, we address the automatic construction of such Reo connectors directly from a constraint automaton representation.

Omówiono wyniki badań mikrobiologicznych powietrza na terenie sąsiadującym z miejską oczyszczalnią ścieków. Pomiary wykonano w latach 2011-2012, uwzględniając wszystkie pory roku. Podstawą do klasyfikacji stopnia mikrobiologicznego zanieczyszczenia powietrza była liczba bakterii mezofilnych, promieniowców, Pseudomonas fluorescens, gronkowców [alfa]- i [beta]-hemolizujących oraz zarodników grzybów. Wykazano, że liczba mikroorganizmów w powietrzu w otoczeniu oczyszczalni ścieków zależała od pory roku i była bardzo zróżnicowana na poszczególnych stanowiskach badawczych, w wielu przypadkach przekraczając wartości charakterystyczne w powietrzu niezanieczyszczonym. Najwięcej drobnoustrojów w powietrzu stwierdzono latem i jesienią, natomiast najmniejsze wartości oznaczono zimą, z uwagi na niską temperaturę ograniczającą przeżywalność mikroorganizmów. Jednocześnie zaobserwowano wyraźny wzrost liczby mikroorganizmów po stronie zawietrznej. Uzyskane wyniki oraz dane literaturowe potwierdzają potrzebę hermetyzowania obiektów oczyszczalni ścieków, a także objęcia ich systematycznym monitoringiem stanu sanitarnego powietrza atmosferycznego.

Air in the vicinity of a municipal sewage treatment plant was assessed for microbial quality. Measurements were carried out in the time span of 2011 and 2012, taking into account seasonal patterns of change. Classification of the extent of microbial contamination was based on the number of mesophilic bacteria, actinomycetes, Pseudomonas fluorescens, [alpha]- and [beta]-hemolyzing staphylococci, and fungal spores. It was demonstrated that the number of airborne microorganisms in the vicinity of the sewage treatment plant followed a seasonal pattern and differed from one measuring point to another, in many instances exceeding the characteristic values measured in unpolluted air. The highest number of microorganisms were determined in summer and fall, and the lowest in winter, when low air temperature limited microbial viability. Simultaneously, a noticeable increase in microbial numbers was observed on the lee side. The results obtained in this study, as well as the available literature data, substantiate the need for hermetizing the objects of the sewage treatment plant and subjecting them to periodical air quality monitoring.

Content available remote Chemical composition and biological properties of weathered drilling wastes
EN
Chemical and biological properties of 8 samples of drilling wastes from the long-term storage sites in the areas of oil various chemical composition (content of petroleum contaminants 0.6-27.6 wt. %, content of toxic heavy metals 117-730 mg/kg d.m.), and a low susceptibility to biodegradation (within the range of 11-58% during the 60-days experiment) were determined. I was found that samples having higher aliphatic/aromatic hydrocarbons ratio were more susceptible to biodegradation. Considering the high contents of the petroleum contaminants, in which the polar component i.e. resins and asphaltenes, are present, all the tested wastes a treat hazard to the environment. The components of potential mutagenic and carcinogenic properties have been found only in the single samples from a wastes series before and after biodegradation.
