The serlogical specificity of the lectin from Lens culinaris

Lens culinaris, the common lentil, contains a lectin which has been shown to be specific for a glycoprotein saliva antigen and a glycolipoprotein serum antigen. Both the saliva and serum precipitin reactions with the lectin are directly inhibited with saccharides, especially those related to D-mannose. Electrophoresis of the serum antigen showed that it migrates as three bands, while appearing as a single band in double diffusion precipitin patterns. Quantitative studies of the saliva antigen levels by hemagglutination inhibition titration indicated a polygenic, quantitative mode of inheritance with a minimum heritability of O. 34. Blood group ABH secretor individuals were found to have a significantly lower mean saliva antigen level than nonsecretor individuals. The lectins from Pisum sativum and Canavaliafiensiformis formed precipitin bands of identity with L.culinaris lectin against saliva. C. ensiformis and L. culinaris lectins exhibited precipitin bands of partial identity against serum; and P. sativum and L. culinaris lectins exhibited a pattern of identity against serum. In addition, precipitin patterns of partial identity with the non-H lectin from Lotus tetragonolobus has been demonstrated. Using Ulex europaeus lectin in hemagglutination inhibition experiments with saliva from blood group O secretor individuals, a minimum heritability of approximately 0.40 for H antigen levels was found. A higher frequency of nonsecretor individuals was observed in the Black population compared with the White population

Impacts of river engineering on river channel behaviour : implications for managing downstream flood risk

Although knowledge of sediment transport has improved over the last 25 years, our understanding of bedload transfer and sediment delivery is still based on a limited set of observations or on models that make assumptions on hydraulic and sediment transport processes. This study utilises repeat lidar survey data of the River Caldew above the City of Carlisle in the UK to investigate the balance of erosion and deposition associated with channel switching from an engineered and managed single thread channel to a naturalising incipient wandering system. Over the 11-year survey period (four bankfull flood events) around 271,000 m3 of sediment were delivered to the river and floodplain and 197,000 m3 eroded suggesting that storage rates of around 7000 m3/annum occurred. The balance of erosion and deposition is influenced by channelisation with very restricted overbank sedimentation and only limited local and transient in-channel bar deposition along the engineered reach (8000 m3 eroded). This contrasts with the activity of the naturalising reach downstream where a developing wandering channel system is acting to store coarse sediment in-stream as large bar complexes and the associated upstream aggrading plane bed reaches and overbank as splay deposits (87,000 m3 stored). Such behavior suggests that naturalisation of channelised systems upstream of flood vulnerable urban areas can have a significant impact on sediment induced flooding downstream. This conclusion must, however, be moderated in the light of the relatively small volumes of material needed to instigate local aggradation in over-capacity urban channels

Our Endangered Heritage Exhibition General Guidelines

OklahomaThe inspiration for the traveling exhibit came about after seeing the Illinois traveling exhibit. Oklahoma modified its panels to appeal to a public audience, as one of its goals is to engage the public in supporting collections care.Traveling Exhibit, Our Endangered HeritageInstitute of Museum and Library Service
