    En el centro histórico de la ciudad de Concordia y con la iniciativa del Municipio se supervisa el desarrollo de las obras de mantenimiento y conservación del patrimonio construido. El presente trabajo comprende la descripción de las estructuras ejecutadas y las diferentes metodologías de construcción de dos edificios nuevos que conservan las fachadas de los edificios históricos originales, en el primer caso el Hotel Imperial de 1890 y el segundo el local de la Ferretería Pierrestegui de finales del siglo diecinueve. Se contemplaron los diferentes plazos de ejecución de las obras y las metodologías adoptadas para poder mantener inalterables las fachadas existentes, de ladrillos comunes en algunos sectores asentados en barro y sus cerramientos originales. Se analizaron previamente en gabinete las secuencias y el proceso de demolición de tal manera de ejecutarlo de forma selectiva y con todas las precauciones inherentes para asegurar los impactos mínimos sobre la obra a preservar. Se ajustó en el desarrollo de las obras la metodología al tener que encarar situaciones particulares, simultáneamente se concientizó al equipo de trabajo sobre la particularidad de las obras

    Kinetic study of Mongolian coals by thermal analysis

    Thermal analysis was used for the thermal characterization of the coal samples. The experiments were performed to study the pyrolysis and gasification kinetics of typical Mongolian brown coals. Low rank coals from Shivee ovoo, Ulaan ovoo, Aduun chuluun and Baganuur deposits have been investigated. Coal samples were heated in the thermogravimetric apparatus under argon at a temperature ranges of 25-1020ºC with heating rates of 10, 20, 30 and 40ºC/min. Thermogravimetry (TG) and derivative thermogravimetry (DTG) were performed to measure weight changes and rates of weight losses used for calculating the kinetic parameters. The activation energy (Ea) was calculated from the experimental results by using an Arrhenius type kinetic model

    Investigation on pyrolysis of some organic raw materials

    We have been working on pyrolysis of some organic raw materials including different rank coals, oil shale, wood waste, animal bone, cedar shell, polypropylene waste, milk casein and characterization of obtained hard residue, tar and pyrolytic water and gas after pyrolysis. The technical characteristics of these organic raw materials have been determined and the thermal stability characteristics such as thermal stability indices (T5% and T25%) determined by using thermogravimetric analysis. The pyrolysis experiments were performed at different heating temperatures and the yields of hard residue, tar, pyrolysis water and gaseous products were determined and discussed. The main technical characteristics of hard residue of organic raw materials after pyrolysis have been determined and the adsorption ability of pyrolysis hard residue and its activated carbon of organic raw materials also determined. The pyrolysis tars of organic raw materials were distilled in air condition and determined the yields of obtained light, middle and heavy fractions and bitumen like residue with different boiling temperature. This is the first time to investigate the curing ability of pyrolysis tars of organic raw materials for epoxy resin and the results of these experiments showed that only tar of milk casein has the highest (95.0%), tar of animal bone has certain (18.70%) and tars of all other organic raw materials have no curing ability for epoxy resin

    Pacific Grove, Cal.,Mch. 7, \u2708.Dear brother John:Yours of late date gladly rec\u27d. Very sorry the Grippe has got you again. Glad to know by late reports from the Valley that you are much better. Thanks for Frank Abbott\u27s letter. I\u27ve written to him, I have also rec\u27d letter from Brad Brown saying he would be here in March. I anticipate a grand visit with him.We are all thankful that Helen is doing so nicely, and sincerely hope she may entirely recover. We are all well here. Sarah is herself again, as smart as ever. She was very sick with bowel trouble --would not take medicine nor have a doctor, and ate nothing. We were very much alarmed, but after weeks she began to mend.The coast has been very stormy all winter. We\u27ve had a good deal of nice weather, and lots of damp and chilly days, I\u27m getting so well that I want to do something and can\u27t find a thing to do -- not much business here, I sincerely hope that this will find you well. Lang may your lum reek. Yours as ever,D. G. Muir04089https://scholarlycommons.pacific.edu/jmcl/30397/thumbnail.jp

    [in margin: [Fig Trees V?]][words on opposite side bleed through paper?]01281Kilmarnock 16th Dec. 1887.Dear Mr. MuirWhen I had the pleasure of visiting you my attention was directed by you to a most magnificent fig tree, & you at the same time mentioned that as a shade tree the fig is superior to all the trees that grow in California. Would it be too much to ask if you would be so kind as supply me with the measurements of the tree _ [girth?]https://scholarlycommons.pacific.edu/jmcl/34561/thumbnail.jp
