Public safety - mandatory vaccinations on school chilldren (also need outline)- - Research Paper Example doza-Vaca representing their minor children presented an Amended Complaint challenging vaccination practice in New York on both the state and the federal law grounds. The plaintiffs claim that they have sincere religious beliefs, which are contrary to immunization practice. In one of their Amendment cause of Action, the three plaintiffs claimed that their religious rights were being violated when the school excluded their children from the school institution because of their religious beliefs thus running counter to the immunization practice. The three plaintiffs argued that the school arbitrarily and unconstitutionally denied their children the right to exercise their religious freedom that was based on the vaccination practice (Phillips v. City of New York. (2014). In this case, the court consolidated the actions of the three plaintiffs. For various reasons, the courts granted the New York City Departments of education and Defendants City of New York motion and dismissed the three plaintiffs on the Amended Protest in its entirety. In reference to Philips vs. New York, number 14-2156-cv, Lynch, Chin and Korman who were the judges upheld the decision of Judge William Kuntz on finding the law passed on constitutional muster. In reviewing the case to terminate pursuant to rule, the judges were supposed to accept the realistic allegations that were set forth by the plaintiffs as true. The children of the three plaintiffs were therefore granted religious exemptions in reference to the mandatory vaccinations. However, despite their religious exemptions, the three plaintiffs still complained of their children’s exclusion from school on every occasion where their children’s schoolmate reported a vaccine preventable disease case. Vaccination against life-threatening diseases remains one of the greatest achievements in health in the United States history. Generally, millions of premature death cases have been prevented while countless children have been rescued from

Biorefinery - Coursework Example Switch grass is current used for the production of biofuel (Jefferson, McCaughey, May, Woosaree, & McFarlane, 2002). Biomass in Alberta Province of Canada (Jefferson, McCaughey, May, Woosaree, & McFarlane, 2002) Biomass Mean annual yield (Mg/h) Prairie sand reed 9.5 Switch grass 7.0 Big bluestem 5.5 Western wheat grass 8.8 Mammoth wild rye 7.7 Green needle grass 15.8 wheatgrass 7.5 Thick spike 6.7 Question 2 The following bio-products can be obtained from the bio-refinery: bio-diesel, ethanol, modified proteins, adhesives and resins, solvents and lubricants as well as industrial plant-based oil products (such as fertilizers, plastics), and plant-made industrial products (such as composites), Propose conversion technologies that can be applied in the biorefinery to produce the identified products; at least two different paths to ethanol should be included Biomass handling technologies for the production of different bio-products from the biomass listed in the Table above involved harv esting, transportation, storage and pre-processing and fermentation or anaerobic digestion. Pretreatment is carried out by hydrolysis of lignocellulosic material with dilute sulphuric acid (0.7-5% v/v) in two stages to yield fermentable sugars such as D-glucose, D-mannose, D-galactose, L-rhamanose, D-xylose, L-arabinose, and uronic acids. The first stage is carried out at 140 Â °C for 15 min to hydrolyze the hemicelluloses and in the second stage proceeds at 190 Â °C for 10 min to breakdown the cellulose. Any residue cellulose is hydrolyzed enzymatic ally. The bioconversion of D-xylose into ethanol from hemicellulosic materials is limited by the presence of toxic compounds, such as phenol, furfural, 5-hydroxymethylfurfural and acetic acid. These toxic compounds decrease the bioprocess productivity. The toxic compounds are removed by use first adjusting the pH to 9-10 by using Ca(OH)2 to facilitate the removal of the toxic compounds and this is followed by readjusting the pH back t o 5. The hydrolyzed hemicellulosic material will be fermented with S. cerevisiae for ethanol production. Alternatively, ethanol can be obtained from the biomass by carrying the pretreatment process by means of steam explosion at 160-290 Â °C, 0.7-5 MPa. The process depolymerizes the cellulose and the hemicellulosic materials. Detoxification and fermentation processes as describe above is carried out to yield ethanol. For each possible path, estimate how much ethanol can be produced per year. Use theoretical yield if the actual conversion efficiency is unknown. Theoretical yield Percentage of cellulose in Switch grass is 40.2% (Jefferson, McCaughey, May, Woosaree, & McFarlane, 2002) Percentage of hemicelluloses in Switch grass = 32.5% (Jefferson, McCaughey, May, Woosaree, & McFarlane, 2002) Hydrolysis of 1 kg C6 sugar polymers gives 1.11 kg monomer sugars Hydrolysis of 1 kg C5 sugar polymers gives 1.14 kg monomer sugars Fermentation of 1 kg glucose (C6) gives 0.511 kg ethanol Theore tical yield = ([(40.2 *1.11) + (32.5*1.14)] * 0.51) Theoretical yield = 41.65/100 = 0.42 kg/kg feed = 0.55 L/kg feed Comment on the logistic aspect (mainly the transportation of feedstock) of the biorefinery, taking into account the scale of operation, the distribution of feedstock, and
