The number of species to be lost in the world drylands is less ; but many crop ( wheat , barley , sorghums , millets , etc. ) and fodder ( medicagos , trifoliums , etc. ) species that form the backbone of world agriculture and pasture husbandry have their origin in arid and semi-arid territories ( Vavilov , 1949 ; Barigozzi , 1986 ) . And what is worse ( incredibile , attamen verum ) , three bold and energetic women of the highest rank and lowest character , Theodora the elder ( the wife or widow of a Roman senator ) , and her two daughters , Marozia and Theodora , filled the chair of St. Peter with their paramours and bastards .

The high resolution picture shown here ( B , above right ) was the first image received by MOC scientists that began to hint at a larger story of layered sedimentary rock on Mars . By applying this algorithm over four photometric bands ( B , V , R and I ) we reduce the possibility of detecting galaxy projection effects and spurious detections instead of real galaxy clusters . The other three panels ( b , c , and d ) represent bow echoes which appear bow shaped on the radar screen and are typically larger in scale than isolated supercells . Methotrexate has been reported to cause blood and bone marrow problems ( fever , chills , sore throat , unusual bruising or bleeding , black , bloody or tarry stools , ) ; lung problems ( unexplained shortness of breath , coughing , or wheezing ) ; stomach problems ( diarrhea , abdominal pain , sores in or around the mouth ) ; liver problems ( yellow skin or eyes , unusual fatigue ) ; kidney problems ( blood in the urine ; darkened urine , swelling of the feet or legs ) ; and others . Virtually every smut or bunt disease once important on cereal grains ( wheat , barley , rice , corn , sorghum , oats ) is or can be effectively managed today by 1 ) seed-treatment chemicals , 2 ) resistant varieties , and / or 3 ) the use of cultural practices such as change in planting date or lengthening the crop rotation .
