Latin American Press Review, Program 1974-18, 1974 April 18
No full textPart I: The Latin American Press Review offers a comprehensive overview of significant developments across the region. It highlights the ongoing struggle for press freedom in Brazil, exemplified by O Estado de São Paulo's steadfast defiance against censorship, underscoring the paper's role as a beacon of journalistic integrity amid Brazil's prolonged military rule. Additionally, the coverage delves into the escalating student protests on Brazilian campuses, signaling a growing discontent with the government and a demand for political reform under the new presidency of General Geisel. However, doubts arise regarding Geisel's proclaimed liberalism as evidenced by the prosecution of Congressman Francisco Pinto for criticizing Chile's General Pinochet, suggesting continued restrictions on free speech. Furthermore, attention is drawn to the plight of Haitian political refugees seeking asylum in the United States, highlighting broader issues of political instability and persecution in Haiti. These reports collectively illuminate the complex socio-political dynamics shaping Latin America, characterized by challenges to civil liberties and human rights amidst authoritarian governance and censorship. In Latin America, the plight of Haitian refugees like Mrs. Marie Sanon highlights their struggle for asylum in the United States due to political repression and violence back home. Despite claims by US authorities that Haiti's regime has liberalized, many refugees argue otherwise, citing ongoing repression and terror. Meanwhile, La Opinión reports on the Central American banana trade, where Standard Fruit's suspension of banana imports from Honduras in response to export taxes threatens the region's economy. Standard Fruit's actions, deemed colonialist by Costa Rican President José Figueres, stem from fears of market competition and the banana producers' growing interest in trade with socialist nations. These stories underscore broader issues of political oppression and economic exploitation in Latin America.

Latin American Press Review, Program 1973-36, 1973 November 20
No full textPart I: The Latin American Press Review examines the aftermath of Chile's coup, noting its impact on regional dynamics, especially regarding Cuba's reintegration efforts. The report also covers Puerto Rico's university strike, highlighting student demands for reform. Shifting focus to Venezuela's upcoming elections, it discusses the leading candidates and the crucial issue of managing oil revenues. Socialist contender José Vicente Rangel's platform is highlighted, emphasizing nationalization and self-reliance. Additionally, Bolivia's call for Latin American autonomy at the Continental Conference of American Foreign Ministers is noted. Finally, the newsletter from London analyzes Chile's socio-economic challenges post-coup. Part II: A historical perspective on Venezuela's oil industry, drawing from Peter Odell's study "Oil and World Power" and other sources. Venezuela, a significant oil exporter, saw a surge in production following the expropriation of oil companies from Mexico in 1938. Both the government and oil companies faced pressures, with the US State Department urging cooperation for regional stability. Despite challenges like competition from the Middle East, Venezuela experienced post-1958 growth, albeit slower than before. The government, aided by technical expertise, negotiated for higher oil profits through taxation. The shift away from concessions toward state control led to concerns about oil reserve depletion beyond 1983. However, the effectiveness of this strategy in bolstering Venezuela's global oil influence remains uncertain.

Designing Soft and Tough Multiple-Network Elastomers: Impact of RDRPs on Filler Network Architecture and Fracture Toughness
No full textPolymer networks are crucial for engineering and biomedical applications; however, their excessive brittleness in the absence of viscoelastic dissipation limits their use in applications requiring high temperatures and water concentrations. Multiple-networks, consisting of a stiff and pre-stretched ‘‘filler’’ network phase embedded within a soft and extensible ‘‘matrix’’ network, offer a promising route to overcome this limitation; yet, the relationship between ‘‘filler’’ network architecture and fracture toughness remains unknown. Here, we synthesized three poly(ethyl acrylate) ‘‘filler’’ networks via free radical polymerization (FRP), RAFT, and ATRP, and assessed the interplay between ‘‘filler’’ network architecture, irreversible chain breakage, and fracture toughness by labelling their crosslinks with fluorogenic mechanophores. These networks had similar elastic chain densities but distinct chain length distributions and mesoscopic structures. They were used to prepare multiple-networks, whose structure and mechanical properties were evaluated using mechanical tests, confocal microscopy, reactive Monte Carlo, and coarse-grained molecular dynamics simulations. Our results reveal that ‘‘filler’’ networks synthesized by RAFT and ATRP yield more brittle multiple-networks than those made by FRP, primarily due to the reduced average extensibility of their ‘‘filler’’ network chains. Their narrower chain length distributions in the load-bearing phase promote strain hardening but compromise energy dissipation through molecular friction and chain breakage, as well as fracture toughness. Overall, these findings underscore the need for advanced gelation methods that provide control over elastic chain distributions within networks, as, without such improvements, the use of RAFT and ATRP may result in long curing times, opacity, and a greater tendency to fracture

Summary Report on Reimers Ranch Trinity Aquifer Observation Wells, Western Travis County, Texas
No full textThis report details an amendment to the Hamilton Pool Source Water Protection Study in western Travis County, Texas, undertaken to address critical data gaps in the Middle and Lower Trinity Aquifers, the primary groundwater resources sustaining Hamilton Pool Preserve and Reimers Ranch Park. The study involved drilling and installing additional monitor wells, resulting in a network of four dedicated monitor wells. Baseline geologic samples (cuttings and core), geophysical logs, geochemical analyses, thin-section descriptions, and hydrogeologic data are presented for these wells with data provided in appendices
