Extent of Implementation of and Level of Participation in the Project Carbon Neutral: The Case of De La Salle Lipa

In response to the call for stewardship, De La Salle Philippines launched the Project Carbon Neutral in 2009. The implementation of this program is being spearheaded by the Lasallian Institute for the Environment (LIFE) and is participated in by all Lasallian schools in the Philippines. The main objective of Project Carbon Neutral or PCN is to benchmark and assess the status of the carbon footprint of De La Salle Philippines (DLSP), the network of Lasallian educational institutions, with the goal of achieving a “green” educational network that is carbon-neutral or better. Since its implementation in 2009, there has been no baseline study conducted along these areas. The extent of implementation and the level of participation of the Lasallian family were looked into in this study. The study surveyed a total of three hundred three (300) purposively sampled members of the De La Salle Lipa community. The mitigating measures of the PCN are perceived to be often implemented and priority is often shown by the Lasallian community. The Lasallian community is perceived to have moderate levels of participation as they often show priority and have fairly supported the activities of the PCN. Geared towards combating the identified problems, this action plan and monitoring and evaluation plan were drafted and put forward

Implementer’s Evaluation of the Community Involvement Programs of De La Salle Lipa

De La Salle Lipa, like other higher educational institutions as mandated by the Commission on Higher Education (CHED), has community extension services in the areas of education, livelihood generation, health and nutrition, good governance, technology transfer, environmental awareness and socio-civic and religious matters. The study was aimed at assessing the Community Involvement Programs of De La Salle Lipa- College Division. Looking at the participation of the faculty members from each college during the school year 2010- 2011, it was found out that majority of them are rendering more than the required number of hours of either internal or external community involvement. It was noted that all the full-time faculty members of the College of Business, Economics, Accountancy and Management (CBEAM) got the rating 5. As to the evaluation done by the implementers on the general aspect of the community involvement in terms of program description, accountability, understanding and refining, progress towards objectives and program long-term outcomes, the respondents regarded the community involvement programs as highly satisfactory with composite means ranging from 3.33 - 3.69. Assessment of the implementation of the community involvement program using goals-based, process-based and outcomes- based evaluations were also done yielding the following composite mean values, 3. 52, 3.19, and 3.16, respectively. Based on the values, the implementer respondents considered the implementation of existing community involvement programs as highly satisfactory despite the relatively lower ratings

Horizons and opportunities in lunar sample science

The lunar sample research program was especially productive, but by no means have all the important answers been determined; continued study of lunar samples will further illuminate the shadows of our knowledge about the solar system.by Lunar and Planetary Sample Team (LAPST).Lunar Sample Science -- Lunar Materials Applications -- Relationship to Missions -- Outlook for Curatorial Operation

Estudio geoquímico de los materiales encajantes de las mineralizaciones de plata del sector oriental del Sistema Central

En este trabajo se han estudiado las características geoquímicas de los materiales que constituyen el medio encajante de las mineralizaciones de La Bodera, Congostrina y Hiendelaenclna. En las tres zonas se ha realizado un estudio lito-geoquímico, en relación con los filones, a partir del cual se ha podido determinar la distribución de los principales elementos metalogénicos y el "contenido metal" de los materiales encajantes. Por otro lado, en la zona de La Bodera. se ha realizado una prospección geoquímica de suelos, para conocer las posibles prolongaciones filonianas y el efecto de las fracturas que afectan al filón principal de la zona

Biolixiviación en columnas de sulfuros polimetálicos del yacimiento de Aznalcóllar (Faja Pirítica Ibérica).

Una alternativa al tratamiento clásico de los sulfuros polimetálicos a través del circuito flotación diferencial - fundición es el desarrollo de procesos hidrometalúrgicos eficientes que permitan la extracción selectiva de cobre, plomo y zinc. Entre las técnicas hidrometalúrgicas, la biolixiviación de menas sulfuradas complejas podría constituir un tipo de proceso limpio, de bajo costo y eficiente para extraer estos metales a partir de los materiales de mina (por lixiviación "in situ", en pila o de escombreras) o para subir selectivamente la ley (en cobre, plomo o zinc) en los concentrados de planta. Esta investigación muestra los resultados de pruebas de lixiviación en columnas, de minerales de la mina de Aznalcóllar, mediante la utilización de soluciones ácidas conteniendo una cepa (ATCC 19859) de Thiobacillus ferrooxidans. Los minerales (8,57 Kg.; pirita-calcopirita-esfalerita-galena; 0,38 por 100 Cu, 4,42 por 100 Zn, 2,11 por 100 Pb) fueron lixiviados continuamente durante 31 semanas. El tamaño de partícula elegido estuvo entre +2,0 mm. (Series DIN 1171; parte inferior de la columna) y - 2,0 + 1,2 mm. (parte superior de la columna). Pruebas de lixiviación continua adicionales fueron realizadas en embudos de decantación (3.000 mi.; 0,9 Kg. de mena; -2,0 +1,2 mm.) durante 28 semanas. Se alcanzaron altas extracciones de zinc (59,9 por 100 - 63,0 por 100) cuando el pH fue nivelado en 2,0. Cuando se pararon las pruebas el proceso de lixiviación continuaba a una tasa sostenida, por lo que puede presumirse que extracciones mayores pueden conseguirse si se emplea más tiempo en el proceso. La precipitación generalizada de minerales refractarios al proceso (e. g. sulfatos férricos) sobre las superficies de los granos de sulfuros fue impedida mediante la no utilización del medio nutriente 9 K durante la lixiviación. La precipitación de sulfatos hidratados de zinc y de hierro ferroso (gunningita, ZnS04 - 6 H20, rozenita y melanterita) tomó lugar bajo condiciones extremas de sobresaturación, y puede ser considerada como un fenómeno restringido que no impidió la extracción de metales

Geochemical Constraints on the Origin of the Ni–Cu Sulfide Ores in the Tejadillas Prospect (Cortegana Igneous Complex, SW Spain)

After the discovery of theAguablanca ore deposit (the unique Ni–Cu mine operating in SW Europe), a number of mafic-ultramafic intrusions bearing Ni–Cu magmatic sulfides have been found in the Ossa–Morena Zone of the Iberian Massif (SW Iberian Peninsula). The Tejadillas prospect is one of these intrusions, situated close to the border between the Ossa–Morena Zone and the South Portuguese Zone of the Iberian Massif. This prospect contains an average grade of 0.16 wt%Ni and 0.08 wt%Cu with peaks of 1.2 wt%Ni and 0.2 wt%Cu. It forms part of the Cortegana Igneous Complex, a group of small mafic-ultramafic igneous bodies located 65 km west of the Aguablanca deposit. In spite of good initial results, exploration work has revealed that sulfide mineralization is much less abundant than in Aguablanca. A comparative study using whole-rock geochemical data between Aguablanca aand Tejadillas shows that the Tejadillas igneous rocks present a lower degree of crustal contamination than those of Aguablanca. The low crustal contamination of the Tejadillas magmas inhibited the assimilation of significant amounts of crustal sulfur to the silicate magmas, resulting in the sparse formation of sulfides. In addition, Tejadillas sulfides are strongly depleted in PGE, with total PGE contents ranging from 14 to 81 ppb, the sum of Pd and Pt, since Os, Ir, Ru and Rh are usually below or close to the detection limit (2 ppb). High Cu/Pd ratios (9700–146,000) and depleted mantle-normalized PGE patterns suggest that the Tejadillas sulfides formed from PGE-depleted silicate magmas. Modeling has led us to establish that these sulfides segregated under R-factors between 1000 and 10,000 from a silicate melt that previously experienced 0.015% of sulfide extraction. All these results highlight the importance of contamination processes with S-rich crustal rocks and multiple episodes of sulfide segregations in the genesis of high-tenor Ni–Cu–PGE ore deposits in mafic-ultramafic intrusions of the region
