1) According to political leaders (“Constant Crisis”), what are the principal aims and values of education in the United States? What are we trying to accomplish through 13+ years of formal schooling? How does this rhetoric stack up against what you believe our aims and values ought to be?
2) Consider the following passages. How ought schools and educators respond to the circumstances described? What can we do? In your experience, what is currently being done, educationally speaking?
Writing in the summer, 2017 Proceedings of the National Academy of Sciences, Gerardo Ceballos, Paul Ehrlich & Rodolfo Dirzo report that:
Earth is experiencing a huge episode of population declines and extirpations, which will have negative cascading consequences on ecosystem functioning and services vital to sustaining civilization. We describe this as a “biological annihilation” to highlight the current magnitude of Earth’s ongoing sixth major extinction event…and the window for effective action is very short, probably two or three decades at most. All signs point to ever more powerful assaults on biodiversity in the next two decades, painting a dismal picture of the future of life, including human life.
Appearing in the August 1, 2018 edition of the New York Times Magazine, Nathaniel Rich writes:
The world has warmed more than one degree Celsius since the Industrial Revolution. The Paris climate agreement—the nonbinding, unenforceable and already unheeded treaty signed on Earth Day in 2016—hoped to restrict warming to two degrees. The odds of succeeding, according to a recent study based on current emissions trends, are one in twenty. If by some miracle we are able to limit warming to two degrees, we will only have to negotiate the extinction of the world’s tropical reefs, sea-level rise of several meters and the abandonment of the Persian Gulf. The climate scientist James Hansen has called two-degree warming “a prescription for long-term disaster.” Long-term disaster is now the best-case scenario. Three-degree warming is a prescription for short-term disaster: forests in the Arctic and loss of most coastal cities. Robert Watson, a former director of the United Nations Intergovernmental Panel on Climate Change, has argued that three-degree warming is the realistic minimum. Four degrees: Europe in permanent drought; vast areas of China, India, and Bangladesh claimed by desert; Polynesia swallowed by the sea; the Colorado River thinned to a trickle; the American Southwest largely uninhabitable. The prospect of a five-degree warming has prompted some of the world’s leading climate scientists to warn of the end of human civilization.
3) Plato’s Cave Allegory is a prominent story of one of the central books of the Western philosophical cannon. It will reappear more than once in the course. As best as you can judge, what does this allegory communicate about the nature and purpose of education or enlightenment?
4) How do these essays compare/contrast with your own experiences and sentiments relating to school? What central thing are these authors getting at?
Sugarcane Bagasse Characterization Distributed: second August, 2018 Last Edited: second August, 2018 Disclaimer: This article has been put together by an understudy. This isn't a case of the work composed by our expert paper essayists. You can see tests of our expert work here.

The real creation of a lignocellulosic biomass is lignin, cellulose and hemicellulose, which is in charge of the structure and inflexibility of plant. These parts has been accounted for to have high potential vitality and are been generally utilized as fuel in car and enterprises. The segments of the bagasse were synthetically portrayed by estimating their dry weight. Table # speaks to the structure of dry sugarcane bagasse dissected in the present examination contrasted and information gathered from other research articles. The dissimilarities in structure of lignin and cellulose may be because of hereditary qualities varieties, developing area, techniques for collecting, developing conditions and explanatory strategies. Table 1. Real segment of sugarcane bagasse Cellulose (%) Lignin (%) References 46 19.6 Display Study 40.57 25.93 (Zeng, Tong, Wang, Zhu, and Ingram, 2014) 25 16.2 (Dhabhai, Jain, and Chaurasia, 2012) 40 23 (Irfan, Gulsher, Abbas, Syed, and Nadeem, 2011) 45.4 23.4 (Pereira, Jacobus, Cioffi, Mulinari, and Luz, 2011) According to the produced information, cellulose content in the bagasse was 46%, which was additionally changed into available shape for the saccharification protein. While the lignin constituted 19.6%, along these lines expulsion of lignin was done by the pre-treatment of bagasse for a productive enzymatic hydrolysis. Cellulose Unit Activity The AumEnzymes, India liberally gave two business cellulases, Acid Cellulase and Neutral cellulase. The cellulase action of Aspergillus terreus, corrosive cellulase, and nonpartisan cellulase were contrasted all together with continue for the streamlining of saccharification stage. The International Unit for compound exercises (IU) of all the three cellulases depended on the aggregate cellulase action and endoglucanase movement, dictated by the CMCase measure and FPU examine individually. Table# speaks to the FPU and CMCase action introduced by all the three proteins. The information in the table# unmistakably reasoned that all the three cellulase have irrelevant aggregate cellulase movement, while they have a high measure of endoglucanase action. Table 2. Correlation of Cellulase Activity Cellulase CMCase Activity (IU) FPU Activity (IU) Aspergillus terreus 0.273 0.045 Corrosive 0.966 0.028 Unbiased 0.223 0.000 Which may demonstrate that all the cellulases has endoglucanase action in any case, the insignificant exoglucanases movement brought about significant decrease altogether cellulase action. Since the Acid cellulase had generally higher catalyst movement, it was additionally utilized as the saccharifying compound. The protein content in the Acid cellulose was discovered utilizing the protein examine and it was observed to be 67.67 μg/mg of Acid cellulase powder. The particular movement was 14.11 IU/mg of Acid cellulase, demonstrating that 14.11 μmol of sugar is discharged by 1 mg of Acid cellulase (protein) in one unit. Enhancement of soluble The measurable outline utilized for the microwave helped soluble pre-treatment is a four components (weight of bagasse, intensity of microwave in wattage, NaOH focus and the presentation era) framework, the reaction of the pre-treatment depended on the cellulose arrangement and lessened lignin after the pre-treatment. The plan synopsis is appeared in the Table #. Table 3.

The quadratic polynomial conditions portrays the relationship between's the huge coefficients i.e. p-esteem (Prob>F) under 0.05 and is utilized to acquire the relapse estimations of coefficients where just huge coefficients are considered. Yet, since this model backings pecking order, the irrelevant coefficients were not overlooked. This condition was utilized to infer the anticipated reactions for cellulose (condition 1) and lignin expulsion (condition 2) Equation1 Condition 2 The ampleness of the quadratic model for the trial reactions (cellulose Y1 and lignin evacuation Y2) was checked utilizing the Analysis of Variance (ANOVA), which was confirmed utilizing the Fisher's measurable model (F-esteem). The table# demonstrates the ANOVA for Y2 reaction. Table 5.

Since the "p-esteem" 0.0014, lesser than 0.005, it shows that the lignin expulsion is touchy to the coefficients/factors in the model. As it were weight of bagasse (A), microwave presentation (B), NaOH (C), BD, A2 and B2 have solid impact on the lignin evacuation. The p-esteem 0.0011 for BD (B-coded for microwave, D-coded for time), demonstrates the solid common communication amongst B and D in expulsion of lignin. The "Absence of Fit F-esteem" of 6.62 legitimizes that there are 5.39% possibilities that such extensive estimations of "Absence of Fit F-esteem" may happen because of commotion, where absence of fit is a blunder that would happen when one of the factor is precluded from the procedure display. Another factual estimation that is a flag to commotion is the ''Adequate accuracy''. The alluring proportion is more noteworthy than 4, accordingly the Adeq Precision esteem is 20.22, this model can be utilized to explore configuration space and further advancement. "Various relationship corfficient or R2" esteem means the connection amongst's watched and anticipated qualities, i.e. in the event that the esteem is more like 1, it implies better relationship. For this situation the R2 esteem is 0.9735, demonstrating better assention between test esteems and anticipated qualities.
