Ton) 100 Algal Oil Current Algal Oil Future Biomass Current Biomass Future 3000 2500 Figure 11. Literature scan demonstrating variability in cultivation yields and estimated cost of algal biomass and biooil, differentiating between "current performance" versus "future projections. Lipid extraction pathways are seen as having a more favorable net energy ratio when anaerobic digestion is incorporated (Quinn et al. The lipid extraction-modeled pathways include wet solvent extraction (Frank et al. The term "cradle-to-grave" refers to accounting for all activities related to the production and use of a product, including activities like recovering natural resources (ores, petroleum, natural gas, coal), converting them to required chemicals and energy utilities, direct energy use during manufacturing the products under study, transportation of materials to the manufacturing plants, transportation of goods to consumers, and use of the goods. This analysis can also consider the effects associated with construction of the manufacturing infrastructure. However, it has also been shown that there is an overestimation of methane yields in the sub-process model validation, relative to anaerobic digestion yields typically discussed in the literature (Quinn and Davis 2015). It is important for pathways employing anaerobic digestion to fully consider the fate of nitrogen that is not recovered from the process residuals and to evaluate fugitive methane emissions from the anaerobic digestion process and from the methane combustion technology (common methane-fired internal combustion engines have higher fugitive emissions than do turbines) (Frank et al. Conduct further analysis of emissions from production facilities construction, which have generally been excluded in analyses. Consider large soil disturbance, including soil removal and grading, during pond construction (Davis 2016). Liners and soil compaction form a barrier to water penetration, including rainfall. The consequences of possible changes in water flows within the local ecosystem requires further consideration. Capital and operating cost estimates are established to analyze annual cash flows for a production facility and estimate economic viability metrics, such as minimum fuel/product selling price, rate of return, or net present value. The overall goal is to capitalize on the flexibility and insight available through application of well-developed computer modeling and engineering analysis tools combined with disparate database information that exists · 172 11. The characteristics of the biological system at the algal cellular level affect the performance of the engineered cultivation system and processes at a higher integrated level. The integrated systems must then in turn function within climate and weather conditions that vary with geographical location, so these approaches need to be both multi-level and multi-scale. System and process simulation and optimization under a systems engineering framework can prove very beneficial for system design and operation. An algal biofuels and co-products supply chain is a complex interdependent system with numerous alternative pathways and functional elements and feedbacks at various spatial and temporal scales and resolutions. Sensitivity analyses on these alternatives and comparative tradeoff assessments across a range of approaches and conditions are among the critical modeling and analysis needs. Efforts have been made to harmonize the different variables used in the analyses (see Sun et al. An analysis of twelve studies that examined cost estimates for the production of 1 gallon of algal oil (specifically, triglyceride), originally ranging from $10. Further details on this harmonization effort will be discussed later in this chapter. Sensitivity analyses for both cultivation systems show that the greatest contributors to production cost are growth rate and composition. While liners provide advantages to algal biomass cultivation (namely reducing leakage, contamination, silt suspension during circulation, and the costs of potential regulatory permitting for these issues) they are a tremendous capital cost that may prove to be prohibitively expensive in the context of low-cost commodity fuels. However, it may be possible to avoid this high capital cost if ponds are located in areas with high soil clay content or if local regulation does not require liners (Davis et al. In the future, alternative solutions may be identified to mitigate pond leakage/percolation.
In spray drying of Dunaliella salina symptoms mononucleosis order 25mg meclizine with visa, lower outlet temperature resulted in higher beta-carotene recovery (Leach et al medications for high blood pressure trusted meclizine 25mg. Freeze drying is used for pharmaceuticals and hormones that cannot tolerate even moderate temperatures medicine - purchase meclizine toronto. Freeze-dried microalgae maintain their chemical symptoms of breast cancer order 25mg meclizine with amex, physical, and biological characteristics for a long time (Vairappan et al. Total lipid content in freeze-dried microalgae was significantly higher than fresh microalgae after a period of storage. Freeze drying is very expensive because providing vacuum conditions requires too much energy (Liapis and Bruttini 2007). Flocculation is used to increase the size of the algae aggregates, and then, air is bubbled through the suspension causing the algal clusters to float to the surface. In addition to flocculant efficiency, recovery is largely dependent on bubble size and distribution through the suspension. Dissolved air flotation facilities require optimized integration with any engineered design for further downstream processing. Centrifugation Centrifugation is widely used in industrial suspension separations and has been investigated in algal harvesting (Molina et al. The efficiency is dependent on the selected species as related to cell size and density excess with the media. Energy requirements are dependent on the bowl diameter, rotational speed, and density of the algal water. Centrifugation technologies must consider large, initial-capital equipment investments; operating energy and costs; and high throughput processing of large quantities of water and algae. Centrifugation is cost and energy prohibitive for first-stage harvesting in large-scale algae biorefineries; it is considered more appropriate as a final dewatering technology (Davis et al. Other Harvesting Techniques A number of other techniques at various stages of R&D have been proposed to harvest and dewater microalgae. These include, but are not limited to , the use of organisms growing on immobilized substrates where the amount of initial water is controlled and the growth substrate can be easily removed; manipulation of electric fields; and bioharvesting, where fuel precursors are harvested from higher organisms. Conveyor belt dryers dry the material on a moving belt while the thin layer of material passes through a series of drying tunnels. The application of heat can be through a convective flow of gas over or through the product. The belt is in contact with circulating hot water (refractance drying-as sold through G3 Enterprises Inc. Algae drying kinetics are measured in thin-layer drying experiments in which the wet sample is placed on a balance in a controlled chamber. The temperature, moisture content, and air velocity as drying media are controlled. Based on this data, moisture content of the sample as a function of time is plotted. Various conditions like air temperature, air velocity, and sample load affect the kinetics of microalgae drying (Molnar 2007). Research has been conducted to observe the effect of different drying conditions on drying characteristics of microalagae. Drying was performed in a convective oven with a constant parallel airflow velocity of 0. The drying-rate curve showed that, at all temperatures, drying occurred at a falling rate with no constrant drying rate, meaning that drying was limited by the diffusion mechanism, and due to resistance of individual cell walls against diffusion of moisture to the top surface. Extracellular polysaccharides in the cell wall may also form a thin membrane on the drying surface, which inhibits moisture diffusion to the surface. Current processing technologies (see chapter 7) utilize feedstock slurries with approximately 20% algae by mass in water. Continued refinement and expanded demonstration of processing strategies at scale and at consistent, high performance over long durations of operation are needed. Importantly, the variety of algal feedstocks utilized by the current industry will need to be tested under processing technologies in order to examine the applicability of approaches over a broad spectrum of species. The quality of feedstock in the performance of these logistics technologies needs to be determined, as well as the potential impact to downstream conversion processes. Even when combining promising harvesting and extraction technologies, significant improvements are still needed for economic and financial success of the industry (Richardson et al. The least amount of energy that is needed for the most innovative harvesting and dewatering technologies is largely unknown and represents a critical gap.

Longer treatment may be necessary for patients who remain severely ill after 5 days of treatment [2]. Unless an alternative diagnosis is made, a full treatment course should be completed by patients with suspected influenza regardless of negative initial test results [2]. Contraindications/Precautions Anaphylaxis and serious skin reactions, including toxic epidermal necrolysis, StevensJohnson syndrome, and erythema multiforme, have been reported [3]. Pharmacology Oseltamivir phosphate, through its active form oseltamivir carboxylate, inhibits influenza virus neuraminidase which affects viral particle release. There are very limited pharmacokinetic data in neonates or preterm infants, but it appears preterm infants would require a lower dose than term infants [6] [7]. Mild rash and gastrointestinal signs, and transient rise in transaminases have been reported in neonates receiving oseltamivir; no abnormal neurologic manifestations were reported. Special Considerations/Preparation Available as 30-mg, 45-mg, and 75-mg capsules and oral suspension (6 mg/mL when reconstituted) [3]. There were no quality issues with the 12 mg/mL product; therefore, the 12 mg/mL suspension may remain in the marketplace and in state or national stockpiles until such supplies expire. To reconstitute oral suspension, add 55 mL of water to bottle and shake well for 15 seconds. Oseltamivir oral suspension contains 2 g of sorbitol per 75 mg dose, which exceeds the 617 Micormedex NeoFax Essentials 2014 maximum daily sorbitol limit in patients with hereditary fructose intolerance, and may cause dyspepsia and diarrhea in these patients [3]. The compounded suspension yields a 6 mg/mL concentration (same as commercially available 6 mg/mL suspension) and total volume adequate for 1 patient for a 5-day course of treatment or a 10-day course of prophylaxis.

Title Oseltamivir Dose Influenza, Treatment: Postmenstrual age less than 38 weeks: 1 mg/kg/dose orally twice daily for 5 days [1]. Postmenstrual age greater than 40 weeks: 3 mg/kg/dose orally twice daily for 5 days [1]. Uses Treatment of confirmed or suspected influenza virus for patients who have severe, complicated, or progressive illness, or who are hospitalized [1] [2]. Treatment should not wait for laboratory confirmation of influenza, but instead be initiated as soon as possible after the onset of symptoms [1] [2], including patients seeking medical attention more than 48 hours after onset of symptoms. The duration of therapy is 5 days [1] [2], but a longer treatment duration may be considered in patients who remain severely ill after 5 days of treatment. Contraindications/Precautions 619 Micormedex NeoFax Essentials 2014 Anaphylaxis and serious skin reactions, including toxic epidermal necrolysis, StevensJohnson syndrome, and erythema multiforme, have been reported [3]. Adverse Effects Most common adverse events reported in pediatric patients are nausea and vomiting [3]. Monitoring Closely monitor patients with influenza for neurologic symptoms or abnormal behavior [3]. Oral Suspension In July 2011, the manufacturer changed the commercially available suspension concentration from 12 mg/mL to 6 mg/mL. The 12 mg/mL concentration will no longer be marketed after current supplies run out [8]. Oseltamivir oral suspension contains 2 g of sorbitol per 75 mg dose, which exceeds the maximum daily sorbitol limit in patients with hereditary fructose intolerance, and may cause dyspepsia and diarrhea in these patients [3]. Emergency Compounding During shortage of commercially manufactured oseltamivir (Tamiflu) oral suspension, the suspension can be compounded using oseltamivir 75 mg capsules.
