Spectroscopic study of photon, ion and electron stimulated molecular synthesis in astrophysical ices
… of stars, gas and dust. Energetic processing of ices and subsequent molecular synthesis in astrophysical environments, including icy Solar System bodies and grain mantles in the interstellar medium, are responsible for the observation of some of the molecular species found in space. Gas phase …

Fish landings, discards and benthic material from demersal trawling in the western English Channel (ICES VIIe)
This study examined the impact of inshore single boat otter trawling from Newlyn, Looe, Plymouth and Salcombe and pair boat demersal trawling from Looe and Plymouth on the benthic environment off the SW peninsula of the UK between 1998 and 2000. Fish and shellfish species (54 and 11 species …

Photometric and spectral analysis of the distribution of crystalline and amorphous ices on Enceladus as seen by Cassini
… a distribution of amorphous and crystalline ices on the southern pole of Enceladus, indicating intense ion bombardment in those latitudes and recent geological activity at the "tiger stripe" cracks. Using a composite mosaic of the satellite, we map this distribution of ices according to a …

Examining the Use of Immersive Clinical Experiences in Athletic Training Education
… to engage in immersive clinical experiences (ICEs), implement behaviors associated with core competencies, and identify strategies that account for patients’ social determinants of health. Educators believe ICEs will help give students a more realistic sense of athletic training practice and …

Consequences of a mobile genetic element integrated at secondary locations
Integrative and conjugative elements (ICEs) are widespread mobile genetic elements that are integrated in bacterial chromosomes, but can excise and transfer to a recipient through conjugation. ICEs are important agents of evolution, contributing to the acquisition of new traits, including …

Interactions between an integrative and conjugative element and its bacterial host
… system. Integrative and conjugative elements (ICEs) are an abundant class of conjugative element. ICEs are typically integrated into the bacterial host chromosome, but under certain conditions, or stochastically, they can excise from the chromosome and transfer to a recipient. ICEs likely …

Autonomous replication of integrative and conjugative elements
… bacteria. Integrative and conjugative elements (ICEs), also known as conjugative transposons, are a large family of mobile genetic elements that can transfer between neighboring cells. ICEs are found integrated in the chromosome of their host bacterium, where they are transmitted to daughter …

Stakeholder perception of client satisfaction after downsizing the Illinois Cooperative Extension Service
… the Illinois Cooperative Extension Service (ICES) organization have on client satisfaction with Extension programming as perceived by: professional county staff, volunteer unit program council members, and members of the county governing boards? And what implications might the perceived …

The merits of the regional seas: programme for Southern Africa
… Council for the Exploration of the Sea (ICES) established in 1902. It was active in the North Atlantic and Baltic Sea areas carrying out scientific studies with investigations concerning exploitation of living and non-living marine resources. ICES later became involved with marine …

Specificity and benefits of an exclusion mechanism for a mobile genetic element in Bacillus subtilis
… including Integrative and Conjugative Elements (ICEs), plays an essential role in bacterial evolution by helping to promote the spread of genes involved in antibiotic and heavy metal resistance, metabolism, symbiosis, and pathogenicity. Like conjugative plasmids, ICEs spread to new hosts by …

Computer Design of Reinforced Concrete Structures.
I. INTRODUCTIONA. ICES is an acronym for Integrated Civil Engineering System, a major computer system dedicated to the advancement of the teaching and practice of civil engineering (7). The system was developed at the Massachusetts Institute of Technology during the mid 1960s. It is a large scale …

Infrared spectroscopy of interstellar grains
Spectra are presented of interstellar 1120 and CO ices in three molecular douds. The high signal—to—noise in many of these enabled high quality comparisons to be made with laboratory data, constraining mantle constituents and thermal history. CGS 4 spectra of H 2 0 ices in the p Oph cloud were best …

Interactions between mobile genetic elements and their bacterial hosts
Integrative and conjugative elements (ICEs) are widespread mobile genetic elements that facilitate the spread of many important genes, including those involved in antibiotic resistance, metabolism, pathogenesis, or symbiosis. These elements are also powerful tools for genetic analyses and …

Interplay between an integrative and conjugative element and its bacterial host
… systems. Integrative and conjugative elements (ICEs) are considered the most abundant conjugative elements. ICEs are MGEs that reside integrated into their host chromosome, excise, and transfer their DNA via conjugation (involving a type IV secretion system) into a recipient. During acquisition, …

Characterization of a bifunctional cell wall hydrolase in the mobile genetic element ICEBsJ
Integrative and conjugative elements (ICEs) are mobile genetic elements that are normally found stably integrated into bacterial chromosomes, but under certain situations can excise and transfer to a recipient cell through conjugation. ICEs contain a set of genes that encode the molecular machinery …

The Water Cycle at the Phoenix Landing Site, Mars
… the site during fall. The onset date of seasonal ices varies annually, perhaps due to variable levels of atmospheric dust. During fall and winter, the CO2 ice layer thickens and sinters into a slab of ice, ~30 cm thick. After the spring equinox, the CO2 slab breaks into smaller grains as it …
