Introduction: We have begun detailed photo-geologic analyses of parts of the north polar region on Mars that expose key geologic elements and relationships. Our goal is to better understand the interplay of local stratigraphy, H 2 O ice and CO 2 frost, climate, and insolation and eolian processes in the development and modification of north polar stratigraphy and geomor-phology. At present, ext...

Aldo-keto reductases tighten coenzyme binding by forming a hydrogen bond across the pyrophosphate group of NAD(P)(H). Mutation of the hydrogen bonding anchor Lys24 in Candida tenuis xylose reductase prevents fastening of the "safety belt" around NAD(H). The loosened NAD(H) binding leads to increased turnover numbers (k(cat)) for reductions of bulky-bulky ketones at constant substrate and coenzy...

The shape diversity among populations of Scartelaos tenuis (Day 1876) from five stations (194 specimens) in the Persian Gulf, Strait of Hormuz (Qeshm Island), and the Sea of Oman were investigated. The shape variation was assessed by geometric morphometrics, using 14 morphological landmarks. The two sexes were not distinguishable by the shape. Fish samples were classified into two distinct grou...

Juncus tenuis Willd. is a warm-season, perennial weed of turfgrass. In wet and compacted soils, it well documented, yet little known regarding the interaction effects compaction soil moisture on its rooting foliar growth. A greenhouse experiment examined above- belowground growth J. tenuis. The experimental design was completely randomized with 3 × arrangement four replications two runs. Factor...
