This project constructs a structural model of the United States Economy. This task is tackled in two separate ways: first econometric methods and then using a neural network, both with a structure that mimics the structure of the U.S. economy. The structural model tracks the performance of U.S. GDP rather well in a dynamic simulation, with an average error of just over 1 percent. The neural network performed well, but suffered from some theoretical, as well as some implementation issues.

In the U.S., many electric utility companies are offering demand-side management (DSM) programs to their customers as ways to save money and energy. However, it is challenging to compare these programs between utility companies throughout the U.S. because of the variability of state energy policies. For example, some states in the U.S. have deregulated electricity markets and others do not. In addition, utility companies within a state differ depending on ownership and size. This study examines 12 utilities’ experiences with DSM programs and compares the programs’ annual energy savings results that the selected utilities reported to the Energy Information Administration (EIA). The 2009 EIA data suggests that DSM program effectiveness is not significantly affected by electricity market deregulation or utility ownership. However, DSM programs seem to generally be more effective when administered by utilities located in states with energy savings requirements and DSM program mandates.

A variety of secondary minerals, formed in response to different oxidation and hydration states, are found in vugs and on fracture surfaces of the basalt cores from DSDP Leg 54. The minerals are smectite (blue to grey), high-magnesium calcite, manganoan calcite, aragonite, iron oxides, phillipsite, todorokite, marcasite, and hydrobiotite. The relationship of the mineral assemblages to four depositional modes of the basalts are delineated. A definite sequence and genetic link exists between mineral type and host rock which is dependent upon the origin and subsequent cooling history of the basalt.

The main tasks of this study were (1) identification of minerals of the clay fraction, (2) identification of clay-mineral associations in relation to stratigraphic intervals, and (3) elucidation of genetic relations of clay minerals with types of sediments and factors of sedimentation. Identification of clay minerals was carried out mainly with an X-ray diffractometer (DRON-I). X-ray diffractograms were prepared by means of CuKalpha radiation, at 35 kW and a current of 20 ma. The scanning rate was 2°/min. Oriented specimens were prepared for the <1-µm fraction (and partly for the <10-µm fraction because of insufficient core material) in three states: air-dried, saturated with glycerine, and heated at 550°C.

Se ha localizado en la Rambla de la Gavarnera en Ibi, Alicante una pequeña población de Ulmus laevis Pall., que no había sido citado expresamente en localidades valencianas, ni en las floras locales, regionales, ni nacionales, en unos casos por no haberse localizado, en otros por considerar a este árbol alóctono en España. Desde hace una década un equipo de la ETSIA de Montes de la Universidad Politécnica de Madrid, viene realizando diversos proyectos y tesis doctorales que han dado como resultado la puesta en valor de esta especie, a través de su localización a nivel nacional, estudio ecológico, fisiológico y genético, que arrojan numerosas pruebas a favor de la autoctonía de esta especie en España. Según los autores de este dilatado proyecto, U. laevis habría tenido en España uno de su principales refugios cuaternarios, aunque en la actualidad se encuentre fragmentado en poblaciones dispersas, con pocos individuos y problemas para su conservación y supervivencia. No obstante esta especie ha demostrado mayores tasas de supervivencia a la enfermedad de los olmos, que otros de sus congéneres como Ulmus minor y U. glabra. En cuanto a su presencia en Alicante, son precisamente estos autores los que localizan un primer ejemplar en Ibi, al que ahora añadimos dos ejemplares más repartidos en tres puntos muy próximos y situados a lo largo de la Rambla de la Gavarnera. Este es un cauce irregular pero con nivel freático permanente, como lo atestiguan la existencia de pozos, azudes, albercas que abastecieron a los pequeños regadíos de la zona, muchos de ellos abandonados en la actualidad. Dada la rareza de esta especie a nivel nacional y la excepcionalidad de su presencia en Ibi, consideramos que el ejemplar de mayor porte merece la consideración de árbol singular para la Comunidad Valenciana y por otra parte, los otros ejemplares merecen su protección y multiplicación, para incrementar la población existente. Es necesario desarrollar un mayor esfuerzo de localización en este paraje y zonas próximas de la Comarca, para conocer su potencial distribución en la provincia y determinar un estatus de protección adecuado.
