(Dartmouth College) Dartmouth's Dickey Center for International Understanding, through its Institute for Arctic Studies, has been awarded nearly $3 million by the National Science Foundation through its Integrative Graduate Education and Research Traineeship program. The five-year grant supports the development of an interdisciplinary doctoral program in the polar sciences and engineering with a focus on rapid environmental change.

| • | Management of Cracking Puddled Soils and its Impact on Infiltration |
| A study of cracking soils management was conducted in the wet soil bin with nine soil management practice treatments to investigate their impact on infiltration rate. The treatments were arranged in a randomized complete block design (RCB) with three replications. It is observed that the management of cracking soils, even at an early stage of crack initiation, has a great influence on infiltration rate. Among the management practices, the hand hoe operation was found to be better than trampling to reduce the cracks when the crack width was 10 mm. It is also observed that there is no influence of crack number on infiltration if a soil management practice is included with irrigation. The study reveals that with a soil management practice, the cracks reduced or were removed in a short period of time even though the cracks were 10 mm wide. In contrast, without soil management, cracks remained open for a long period even after ponding. By practicing soil management during irrigation, a large volume of water can be saved which my help to bring more area under irrigation particularly where there are limited water resources. | |

| • | Correlation between nucleotide composition and folding energy of coding sequences with special attention to wobble bases. |
| Background: The secondary structure and complexity of mRNA influences its accessibility to regulatory molecules (proteins, micro-RNAs), its stability and its level of expression. The mobile elements of the RNA sequence, the wobble bases, are expected to regulate the formation of structures encompassing coding sequences. Results: The sequence/folding energy (FE) relationship was studied by statistical, bioinformatic methods in 90 CDS containing 26,370 codons. I found that the FE (dG) associated with coding sequences is significant and negative (407 kcal/1000 bases, mean +/- S.E.M.) indicating that these sequences are able to form structures. However, the FE has only a small free component, less than 10% of the total. The contribution of the 1st and 3rd codon bases to the FE is larger than the contribution of the 2nd (central) bases. It is possible to achieve a ~ 4-fold change in FE by altering the wobble bases in synonymous codons. The sequence/FE relationship can be described with a simple algorithm, and the total FE can be predicted solely from the sequence composition of the nucleic acid. The contributions of different synonymous codons to the FE are additive and one codon cannot replace another. The accumulated contributions of synonymous codons of an amino acid to the total folding energy of an mRNA is strongly correlated to the relative amount of that amino acid in the translated protein. Conclusion: Synonymous codons are not interchangable with regard to their role in determining the mRNA FE and the relative amounts of amino acids in the translated protein, even if they are indistinguishable in respect of amino acid coding. | |
