Soil-borne microbial communities were examined via a functional gene microarray approach across a southern polar latitudinal gradient to gain insight into the environmental factors steering soil Nand C-cycling in terrestrial Antarctic ecosystems. The abundance and diversity of functional gene families were studied for soil-borne microbial communities inhabiting a range of environments from 51 degrees S ( cool temperate – Falkland Islands) to 72 degrees S ( cold rock desert – Coal Nunatak). The recently designed functional gene array used contains 24 243 oligonucleotide probes and covers 410 000 genes in > 150 functional groups involved in nitrogen, carbon, sulfur and phosphorus cycling, metal reduction and resistance and organic contaminant degradation ( He et al. 2007). The detected N- and C-cycle genes were significantly different across different sampling locations and vegetation types. A number of significant trends were observed regarding the distribution of key gene families across the environments examined. For example, the relative detection of cellulose degradation genes was correlated with temperature, and microbial C-fixation genes were more present in plots principally lacking vegetation. With respect to the N- cycle, denitrification genes were linked to higher soil temperatures, and N-2-fixation genes were linked to plots mainly vegetated by lichens. These microarray-based results were confirmed for a number of gene families using specific real-time PCR, enzymatic assays and process rate measurements. The results presented demonstrate the utility of an integrated functional gene microarray approach in detecting shifts in functional community properties in environmental samples and provide insight into the forces driving important processes of terrestrial Antarctic nutrient cycling.
FacebookTwitterLinkedInEmailSALT LAKE CITY-As confirmed Thursday, Utah athletics cumulatively had a strong academic campaign in 2018-19 as the Utes collectively achieved a 3.25 GPA across the landscape of 20 sports.In the fall, the Utes’ athletic teams in that season netted a collective 3.30 GPA and the spring squads posted a collective 3.18 GPA.This is the 26th straight semester that University of Utah student-athletes have achieved a cumulative GPA of 3.0 or higher.Sixty athletes netted a 4.0 GPA as well for the Utes.Four Utah athletics teams achieved a collective GPA of 3.5 or higher, including gymnastics, women’s skiing, track and field and cross country.

The company has become increasingly efficient during the production of this vessel series.In mid-August, the third vessel in this class, Stratton, underwent sea trials and passed with flying colors.“This successful sea trial is a positive reflection of the efficiencies established during the construction and testing of this ship,” said Mike Duthu, Ingalls’ Program Manager.The shipbuilder reduced the construction schedule compared to the previous vessel in the series and improved labor costs by reducing man-hours.ShipConstructor’s Autodesk-based CAD/CAM software helped enable these efficiencies due to its innovative change management technology.As the shipbuilder gained experience during production of multi-series vessels, they discovered more efficient ways to do things and those improvements had to be reflected in the 3D model and all the associated production drawings. Fortunately, ShipConstructor allows this process to happen seamlessly.ShipConstructor Software Inc. is continually improving its flagship software’s change management engine which uses what it calls “Associative DWG” technology to link all the drawings together via a Microsoft SQL Server Relational Database. The result of the technology is that a change made in one area of the model is reflected in other views and associated production drawings can be updated semi-automatically.[mappress]Source: shipconstructor, November 07, 2011 View post tag: Efficiency Industry news November 7, 2011 Back to overview,Home naval-today Canada: ShipConstructor Software Helps Improves Ingalls’ Efficiency View post tag: helps Share this article
