Chemical Oxygen Demand Reduction Using The Algae Dunaliella Primolecta And Chlorella Vulgaris, Angeles L. Mora, Alejandro Hernandez, Alejandro Calderón-Urrea Aug 2015

Chemical Oxygen Demand Reduction Using The Algae Dunaliella Primolecta And Chlorella Vulgaris, Angeles L. Mora, Alejandro Hernandez, Alejandro Calderón-Urrea

STAR (STEM Teacher and Researcher) Presentations

Farm industry wastewater is characterized by high organic materials and by high chemical oxygen demand (COD). Farms with large livestock and poultry operations can be a major source of wastewater thus a major concern for effective environmental and industrial management. Effective environmental and industrial management are high in cost therefor biofuels produced from plants have a potential of replacing a portion of fossil fuel consumption with a renewable efficient alternative. Due to California’s water crisis in the recent years, it is questioned if a biological treatment system that uses algal growth to create renewable energy in the form of ...

Microbes such as algae and bacteria are promising candidates for supporting extended human space travel, as they are robust sources of food, fuel, waste cycling, and oxygen production. Growing microbes on membranes reduces the mass and water demands of a bioreactor system, both of which are important considerations in space travel. The European Modular Cultivation System (EMCS) on the International Space Station (ISS) provides an ideal opportunity to test the effects of microgravity and other aspects of the space environment on algal growth on membranes. This project aims to find optimal growing conditions and measurement technologies that conform to the ...

Graduate Internship Report - Ann Sobrato High School, Adeline Grace Amador

Graduate Internship Reports in Agricultural Education

This internship report includes validation documents required in meeting the quality criteria for secondary-level programs of instruction in agriculture. The documents are concurrently used for the Agriculture Incentive Grant review process at Ann Sobrato High School conducted by representatives of the California Department of Education. The internship included the restructuring and designing of the curriculum for an Agriculture Leadership class. It also includes development of a set of directions and a scoring rubric for the FFA iRecordbook. Finally, it includes the redevelopment of curriculum for Agriculture Biology and Agriculture Geology classes related to the Next Generation Science Standards. This includes ...


Father Convict Cichlids Bite Intruders More Often In Hot Temperatures, Jesse L. Heckendorf Jan 2015

Father Convict Cichlids Bite Intruders More Often In Hot Temperatures, Jesse L. Heckendorf

STAR (STEM Teacher and Researcher) Presentations

Convict cichlids (Archocentrus nigrofasciatus) have evolved to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a male convict cichlid’s aggression toward caring for his offspring when an intruder is introduced. Male convict cichlids attack more in warmer water.
