In two families with severe sex-linked muscular dystrophy, high levels of alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LD), aspartate transaminase (AspT), aldolase, and creatine phosphokinase (CPK) were found in the sera of three young affected males. In both families the mother had a raised level of HBD activity. Four sisters of the three affected boys had raised serum enz...

Freshwater ecosystems in the Indo-Burma biodiversity hotspot face immediate threats through habitat loss and species extinction. Systems to monitor ecological status trends are therefore crucially needed. Myanmar is part of but with no past experience biomonitoring freshwaters. In this study, we aimed assess a lowland river network south-central by identifying quantifying pressures using macroi...

Let G be an n-node and m-edge positively real-weighted undirected graph. For any given integer f ≥ 1, we study the problem of designing a sparse f-edge-fault-tolerant (f -EFT) σ-approximate single-source shortest-path tree (σ-ASPT), namely a subgraph of G having as few edges as possible and which, following the failure of a set F of at most f edges in G, contains paths from a fixed source that ...

• A global overview of river assessment methods using macroinvertebrates. Correspondence between pressures and applied. Riverine macroinvertebrates successfully detect human impacts worldwide. Pitfalls to applications are identified. common macroinvertebrate metric for proposed. The aim this study is generate a first used assess the environmental quality rivers streams In total, 314 peer-review...

Let G be an n-node and m-edge positively real-weighted undirected graph. For any given integer $$f \ge 1$$ , we study the problem of designing a sparse f-edge-fault-tolerant (f-EFT) $$\sigma $$ -approximate single-source shortest-path tree ( -ASPT), namely subgraph having as few edges possible which, following failure set F at most f in G, contains paths from fixed source that are stretched by ...

biological monitoring using benthic organisms is one of the best and the most inexpensive methods for anthropogenic activities evaluation in aquatic ecosystems. the purpose of present investigation was biological monitoring of shahrud river that was performed in the qazvin province using by macro benthic invertebrates population. in the present investigation macro benthic invertebrate samples w...
