Chemical analysis of the biomass of a native strain of Spirulina subsalsa Oersted ex Gomont 1892 (Spirulinaceae) cultivated in low-cost saline medium

Spirulina subsalsa, a filamentous cyanobacterium, was first described by Gomont in 1892. This microorganism has been subject to biotechnological evaluations, due to their high content of proteins and pigments. The objective of this study was to analyze the biochemical composition of the biomass of a native strain of S. subsalsa cultivated in low-cost saline medium and harvested in the exponential and stationary phases...

A dry gas material balance with an infinite aquifer influence: A comparative study between the unsteady state model of van Everdingen-Hurst and analytical model

Aquifer water influx is an important natural mechanism for primary recovery. It affects the performance of all types of reservoirs, also natural gas reservoirs. Water influx provides pressure support during reservoir depletion, resulting in slower pressure decline. Consequently, gas reservoirs associated with large aquifers show a flattening, cubic behavior of the p/z vs. Gp curve, which allowed the development of the...

Gravitational waves as a test of general relativity

General relativity has been very successful as a model for space and gravity. It is supported from a range of experimental results. With the advent of the detection of gravitational waves, another platform exists to trumpet its triumph. The merger of black holes has provided evidence in support of the theory of Einstein. Furthermore, the one neutron star merger so far detected provides much more information because of...
