Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in g...

Surgical resection in mmspected intralobar sequestration can result in fatal hemorrhagic complications. The roentgen criteria for establishing tbis diagnosis are: 1) chronic and recurrent pulmonary Wtrate; 2) most often located in b a s k segments of the lower lobes; 3) multiple cystic areas; 4) failure of contrast media to enter the cystic area during broncbography. We studied two cases of int...

The soil holds twice as much carbon as does the atmosphere, and most soil carbon is derived from recent photosynthesis that takes carbon into root structures and further into below-ground storage via exudates therefrom. Nonetheless, many natural and most agricultural crops have roots that extend only to about 1 m below ground. What determines the lifetime of below-ground C in various forms is n...

Plantation agriculture is more than 400 years old and contributes to the regional and national economies in many tropical countries. This paper reviews some of the main environmental issues related to plantation agriculture with perennial crops, including soil erosion, soil fertility decline, pollution, carbon sequestration and biodiversity. Soil erosion and soil fertility decline are of concer...

Agriculture in the southeastern USA can be highly productive (i.e., high photosynthetic fixation of atmospheric CO2) due to warm-moist climatic conditions. However, its impacts on greenhouse gas emissions and mitigation potential have not been thoroughly characterized. This paper is a review and synthesis of literature pertaining to soil organic C (SOC) sequestration and greenhouse gas emission...

the radiologic features of intralobar pulmonary sequestration (ilps) have been describe and include the identification of a feeding systemic artery with venous drainage through pulmonary veins. primary sequestration associated with typical hamartoma signs is really rare and has been described only once. we describe a patient with ilps whose radiographic findings were unusual for two reasons. fi...

Abstract The organic-rich upper Lower Jurassic Da'anzhai Member (Ziliujing Formation) of the Sichuan Basin, China is first stratigraphically well-constrained lacustrine succession associated with Toarcian Oceanic Anoxic Event (T-OAE; c. 183 Ma). expansion palaeo-Sichuan mega-lake, probably one most extensive freshwater systems to have existed on planet, marked by large-scale organic productivit...
