Due to the energy crisis that some countries are facing nowadays, the gasification process appears to be a good alternative to produce some energy from solid materials. Increasingly, gasification involves using wastes as a solid fuel, making the process green and reusing some materials that otherwise could end up in a landfill. However, the process of finding the best gasification parameters of a sample can be very expensive and time-consuming. In this sense, a refuse-derived fuel (RDF) char produced from an original RDF under 30 min at 400 °C was tested on a small-scale reactor using macro thermogravimetric analysis (TGA), as presented in this paper. The goal was to study and evaluate the devolatilization and residual carbon rate of the sample under several conditions and, at the same time, quantify and analyze the released gas. In the first round of tests, 5, 10, and 20 g of samples were tested at 750 °C with an excess of air coefficient (λ) = 0 and 0.2. It was possible to conclude that the lower the mass, the higher the devolatilization rate. The λ only had an influence on the devolatilization rate with a 20 g sample. Regarding the gas, CO, CO2, and H2 had no variation in the sample mass in contrast to CH4, which increased with the increase in the sample mass. The second round of tests was performed with samples of 10 g of mass at temperatures of 700, 800, and 900 °C and λ values of 0.15, 0.2, and 0.25. The tests indicated that the temperature influenced the devolatilization rate but not the residual carbon combustion rate. Regarding the gas composition, CH4, CO2, and CO followed the same trend, decreasing the concentration with the increase in temperature; in contrast, H2 increased in concentration with an increase in temperature. The heating value of the gas followed the same behavior as CH4.

Blog Post: Immigration Reform: Lessons Learned and A Path Forward

Owen Lubozynski, Cornell Law, Mar. 7, 2023 “Congress has been unable to enact comprehensive immigration reform for over thirty years. On February 24, at the National Press Club in Washington, D.C., a diverse group of policymakers, experts, advocates, students, and stakeholders convened to explore what it would take to change that. They were presenters and attendees at “Immigration Reform: Lessons Learned and A Path Forward,” a conference sponsored by Cornell Law School’s Immigration Law and Policy Research Program and cosponsored by the Cornell Migrations Initiative. Both in-person and over Zoom, about 220 people attended the conference, which explored targeted legislation and other policy changes that could be enacted in 2023. Panels focused on three topics: work visa changes to help alleviate high-skilled and low skilled-labor shortages, border security and asylum reforms, and a permanent path forward for Dreamers, farmworkers, and others. “Major reforms require the convergence of a widely recognized problem, policy solutions, and sufficient political will,” says Stephen Yale-Loehr, conference co-organizer and Cornell Law professor of immigration law practice. “Our conference brought together expert scholars, analysts, and advocates to probe ways to clarify key problems, identify achievable policies, and build the political will needed to enact them. We hope to build on the conference discussions to develop constructive proposals that have a realistic chance of enactment this year.” The keynote was given by economist Douglas Holtz-Eakin, president of the American Action Forum. Holtz-Eakin made an argument for the benefits of immigration based on a set of driving economic forces: enormous global pressure for economic migration paired with the United States’ sub-replacement fertility, declining labor pool, and skills deficits. Noting the recent slowing of the country’s GDP growth, he said, “There’s a palpable sense of the American Dream just disappearing over the horizon.” On a more hopeful note, he observed that the United States “has never really used economic policy as an important component” of immigration reform and that, by doing so, we might find that the shared desire for economic growth could unify the disparate parties involved. “In the absence of immigration, we get older, we get smaller, our economy shrinks, our ability to project our values on the globe diminishes, and we become a shadow of our former selves,” he said. “The flip side to that is that the immigration decisions we make get to dictate our future.” The day’s first panel, on the border crisis and asylum reform, was moderated by co-organizer Stephen Yale-Loehr, Cornell Law professor of immigration law practice, and featured Muzaffar Chishti, of the Migration Policy Institute; Kristie De Peña, of the Niskanen Center; Glenn Hamer, of the Texas Association of Business; Mathew Johnson, of the Klein/Johnson Group; and Rebecca Tallent, chair of the National Immigration Forum board of directors, former chief of staff to Senator John McCain, and adviser to former House Speaker John Boehner. This was followed by a panel on immigration and worker shortages moderated by Randel Johnson, distinguished immigration scholar at Cornell Law, and featuring Jon Baselice, of the U.S. Chamber of Commerce; Josh Bernstein of the SEIU; Scott Corley, of Compete America; Giev Kashkooli, of the United Farm Workers; Craig Regelbrugge, of AmericanHort; and immigration law and policy expert Amy Nice. A final panel on Dreamers and the undocumented, moderated by Charles Kamasaki, distinguished immigration scholar at Cornell Law, featured Theresa Cardinal Brown, of the Bipartisan Policy Center; Galen Carey, of the National Association of Evangelicals; Jennie Murray, of the National Immigration Forum; Gaby Pacheco, of TheDream.US; and Rebecca Shi, of the American Business Immigration Coalition.”

Administration proposes new student leadership structure, causing mixed reactions from students

Administration has proposed a change to student leadership that would combine the different leadership groups within the school. Currently the Student Government Association (SGA) and Senior Planning (Splanning) have two separate class periods to plan for their organizations events. Ninth, 10th and 11th grades also have class planning groups that operate as clubs, meeting during lunch or after school.

The SGA class is led by student elected co-presidents. SGA’s main responsibilities are planning homecoming, the spring project and presenting testimony to the Board of Education. Splanning is a class made up of seniors, led by the senior class officers, and is mainly responsible for senior events including Putting on the Hits, prom and graduation. “Each leadership class or club in our school has a different priority and purpose. I think our leadership structure should remain the same, a change will only make it more difficult to get things done,” junior class president Kelly Ren said.

Administration’s proposed leadership plan would combine SGA, class planning officers of all grades, Patriot Ambassador representatives, student union representatives, athletic leadership council members and advocacy group representatives into one class. The SGA co-presidents will lead the class, class officers will lead under them and be renamed “senators” and representatives from the various other clubs would make up the rest of the class. “I think it’s time for a change and I’m glad administration is willing to work with us and listen to our concerns,” SGA junior Tati Pacheco said.

This proposed change was prompted by Principal Douglas Nelson’s desire for school activities to be more organized and for the planning of these events to include a wider range of students. As a first year principal, Nelson believes in reevaluating the structures in place in order to make improvements where he can within the school. “I’ve noticed that some of the work that SGA does and the work of Splanning seems to have a lot of overlapping. In some ways I don’t believe those activities work as well as they could, and I think that it’s reasonable to pose the question: If they are brought together in some way and they don’t exist separate from one another, are we possibly bringing these groups together in a way that will work better?” Nelson said.

While a major goal of the proposed leadership structure is to include more students in the planning of events, not all students agree it will have this effect. “The point of the reconstruction is to make class planning more inclusive and structured. This will do the opposite. It will create chaos. By taking the Splanning class away it will give students little motivation to participate,” a freshmen class officer said.

Ren shares the concern of decreased student participation if the proposed leadership structure is implemented. “The first semester of senior year is stressful with college applications and I’m worried that without a designated period, seniors will not have time out of school to plan our necessary events,” Ren said.

Sophomore Nikki Cohen, a member of sophomore planning, understands both perspectives. “I feel like getting rid of senior planning could have positives and negatives. On one hand it could give more students opportunities to participate in class planning. On the other hand it could lead to an unorganized structure and be taken less seriously, which is unfair to the students who are really committed to class planning,” Cohen said.

Nelson acknowledges that the proposed leadership structure may pose difficulties and that having devoted time to planning class events is beneficial. But Nelson questions whether it is essential. “Why do all high schools not do it this way? I can’t imagine how at Wootton we face something truly different than 26 other high schools in the school system. If other schools don’t necessarily have their student leadership in this structure, then I think we can figure that one out,” Nelson said.

Another reason administrators raised for the proposed leadership change was bias within the selection process for the SGA and Splanning classes. Typically the criteria to decide which students are admitted into the Splanning class is based on involvement and participation in class events throughout high school, although the specific criteria varies with each senior class. To be admitted into the SGA class students must go through an application and interview process, with the final decision being made amongst a group of students in SGA. “I had a really negative experience applying to SGA last year. I felt my interview was really unprofessional. They asked inappropriate questions and made me feel inferior. I later found out they made rude remarks about me in a shared Google document, saying I was the worst interview they had,” an anonymous junior said.

Administration has allowed for student input through listening sessions and changes to the proposal have been made since hearing students’ voices, though Nelson could not speak to the specific adjustments. The leadership structure for next year has yet to be finalized and administration does not know when a final plan will be announced. Until then, students anxiously await to hear how their leadership roles within the school will be impacted and if they will be a part of the proposed student leadership class for next year.

From Humble Beginnings to Political Power: The Life and Legacy of Ramón Ismael-Pachecho

Introduction:

Ramón Ismael-Pachecho is a name that resonates in the political sphere of Costa Rica. Born into humble beginnings, he rose to become one of the most influential figures in the country’s history. This detailed biography will delve into the various aspects of his life, from his early years to his political career, highlighting his accomplishments and examining the lasting impact he left on Costa Rica.

Chapter 1: Early Years and Education

Ramón Ismael-Pachecho was born on February 22, 1924, in San José, Costa Rica. He grew up in a modest family with limited resources but possessed an insatiable thirst for knowledge. Despite financial constraints, his parents recognized his potential and encouraged him to pursue education.

Pachecho attended local schools where he displayed exceptional academic abilities. His intellectual curiosity led him to excel in various subjects, particularly history and politics. His passion for these fields began to shape his aspirations from an early age.

Chapter 2: College Years and Activism

After completing high school with top honors, Pachecho continued his education at the University of Costa Rica. There, he pursued a degree in Law and Political Science while actively engaging in student activism.

Pachecho quickly became known as a charismatic leader who advocated for social justice and equality. He played a significant role in organizing student protests against governmental corruption and economic inequality. These experiences shaped his ideologies and propelled him towards a career devoted to public service.

Chapter 3: Early Political Career

In 1953, Ramón Ismael-Pachecho embarked on his political journey by joining the National Liberation Party (Partido Liberación Nacional – PLN). The party’s progressive platform aligned with Pachecho’s beliefs; thus, it became the perfect vehicle for him to enact change.

Pachecho’s political career gained momentum when he was elected to the Legislative Assembly in 1958. As a representative, he tirelessly advocated for social and economic reforms, championing causes such as land redistribution and workers’ rights. His commitment to these issues earned him widespread popularity among the working class and marginalized communities.

Chapter 4: Rise to Power

In 1962, Pachecho’s dedication to public service propelled him further as he won the presidency of Costa Rica. At 38 years old, he became the youngest president in the country’s history, marking a turning point in his political career.

During his presidency, Pachecho implemented an ambitious agenda centered around social justice and economic development. He tackled issues such as poverty alleviation, education reform, and healthcare improvements. His policies aimed to bridge the gap between the rich and poor while promoting sustainable growth for Costa Rica.

Chapter 5: Challenges and Controversies

While Pachecho’s presidency brought about significant progress and positive change, it was not without challenges and controversies. One of the most notable controversies occurred during his term when he nationalized several industries, including banking and telecommunications. This move sparked intense debates both domestically and internationally regarding the role of government in a free-market economy.

Additionally, Pachecho faced criticism for his confrontational approach towards political opponents. His strong personality often clashed with fellow politicians, causing friction within his own party at times. Despite these challenges, Pachecho remained steadfast in his pursuit of a more equitable society.

Chapter 6: Legacy

Ramón Ismael-Pachecho’s legacy is one that reverberates throughout Costa Rica even after his departure from politics. His presidency left an indelible mark on the country’s socio-economic landscape.

Pachecho’s policies contributed significantly to reducing poverty rates while improving access to education and healthcare services for all Costa Ricans. He successfully transformed Costa Rica into a model for sustainable development, emphasizing environmental conservation and green initiatives.

Furthermore, Pachecho’s commitment to social justice paved the way for subsequent generations of leaders who continued his work. His influence extended beyond his presidency, inspiring others to fight for equality and justice.

Conclusion:

Ramón Ismael-Pachecho’s life journey is an inspiring testament to the power of determination and vision. From humble beginnings, he rose to become a transformative figure in Costa Rican politics. Through his unwavering commitment to social justice and economic progress, he left an enduring legacy that continues to shape the nation today. Ramón Ismael-Pachecho’s story serves as a reminder that one individual can make a significant impact on society by channeling their passion into action.
