Rhizobium-legume symbiosis and nitrogen fixation under severe conditions and in an arid climate

Article Abstract:

Nitrogen fixation and Rhizobium-legume symbiosis where conditions are severe and in arid climates are discussed. For improvement of soil fertility and rehabilitation of arid lands, this symbiosis is an ideal solution. Several strains in various rhizobia species are tolerant to such stress effects as acid stresses, salt, and heat, sometimes under influence of heavy metals.

Black gunners at Bastogne

Article Abstract:

Bastogne, the 101st Airborne Division, received a huge share of recognition in the battle of Bulge for its defiant defense at the crossroads in December 1944. The black gunners at Bastogne won the coveted Distinguished Unit Citation by fighting with paratroopers, glider infantrymen, white cannoneers and tankers in that grim struggle.

A minority no more

Article Abstract:

Hispanic students at FIU are in danger of losing scholarships now that they make up almost 50% of the student body. New Dept of Education rules will allow universities to award scholarships based on ethnicity only if that group is underrepresented. Maidique's plans to protect federal funds are discussed.
