Genetic analysis of two species of Mnomen in the Kalamazoo Watershed reveal panmixia in Z. Aquatica, structure among Z. Palustris, and hybridization in areas of sympatry
Mnomen or wild rice of the genus Zizania is an important part of Native American culture, especially in Michigan for the Ojibwe nation. An oil spill in 2010 along the Kalamazoo River and the subsequent clean-up lead to renewed interest in management of Mnomen within the Kalamazoo watershed. The affected water bodies were surveyed for Zizania species to map existing populations, determine the existing genetic diversity and species present, and to identify potential hybridization. Using Traditional Ecological Knowledge of rice beds and opportunistic sampling of encountered plants, 28 rice beds were sampled. Two species of Zizania were identified Z. palustris and Z. aquatica. Genetic diversity was measured using 11 microsatellite loci and was moderately high for both species (Z. aquatica HE = 0.669, H0 = 0.672, n = 26 and Z. palustris HE = 0.697, H0 = 0.636, n = 57). No evidence of population bottle-necking was found. Z. palustris was found to have k = 3 populations on the landscape, while Z. aquatica was found to be a single panmictic population. Several individual hybrids were confirmed using genotyping and they were all found in areas where the two species co-occurred. Additionally, Z. aquatica was found to have expanded into areas historically with only Z. palustris downstream of the oil spill, potentially due to dredging and sediment relocation as part of the clean-up effort

Anaerobic Resistance to High Levels of Cadmium and Other Toxic Metals in a Facultative Anaerobe Isolated From Pristine Salt Marsh Sediments
The authors have isolated many Cd (II) resistant bacterial strains from relatively pristine sediments collected from salt marshes in Shelter Island, New York. Detailed studies are being performed on one isolate, strain Cd-1. Strain Cd-1 is metabolically diverse, halotolerant, Gram-negative, facultative anaerobe. It can resist high amounts of Cd (II), Cr (VI), As (V), Se (IV), Co (II), Pb (II), or Zn (II) under defined anaerobic conditions. With pyruvate as the energy source, Cd-1 can grow well at examined Cd (II) concentrations ranging up to 15 mM. It can resist Cd (II) with or without marine level NaCl concentration, under acidic or neutral conditions. It can resist Cd (II) under aerobic conditions as well. These features are novel for a heavy metal resistant bacterium

Automatic control system „master ” for power industry logic
System Automatyzacji MASTER, jest w pełni polskim
systemem opracowanym w Instytucie. Jest na bieżąco optymalizowany i unowocześniany w zakresie sprzętu i oprogramowania. Oprócz nieograniczonej możliwości rozszerzania puli standardowych linków komunikacyjnych umożliwia aplikację dowolnych firmowych protokołów. Zapewnia wystarczające zasoby i mechanizmy do kompleksowych automatyzacji obiektów jak również tworzenia heterogenicznych instalacji poprzez łatwą integrację z systemami innych producentów.MASTER Automation System is an entirely Polish system elaborated in the Institute. It is being currently updated and
optimized in the range of hardware and software. Apart from an unlimited ability to extend the amount of standard communication
links it will enable application of any Institute’s procotols. It ensures sufficient resources and mechanisms for an objects
complex automation as well as for creation of heterogenous through easy integration with other producents systems
Exemplary industrial system and network modeling in Poland
The paper presents the exemplary industrial
system models from the event-driven simulator up to
Approximate network analytical performance evaluation
system tool (Anapest). The basic approximations assumed
in Anapest are roughly discussed together with the basic
network configuration for which the tool was developed.
The two basic ways of Anapest validation, i.e. the internal
network measuring tool Sitwa and event-driven simulation
are depicted. In addition, the major network performance
evaluation projects run till now described, together
with the basic outcome from Anapest
