H.W.M. Olbers measurements of air temperature in Bremen from 1803 to 1822

We rediscovered a temperature time series from Heinrich W. M. Olbers. Heinrich W. M. Olbers measured in Bremen, Sandstrasse 15, in Germany from 1803 to 1821 three times a day (7 am, 1-2 pm and 10 pm) the temperature at his window of his study, which is up to 16 m above the zero marking at the Weserbrücke. The temperature values from 1814 are missing. We got the temperature values from different sources in the Olbers estate. We calculated the daily mean and digitized it in various plots. A very small trend towards cooling is apparent in the data which might be insignificant. But a clear seasonal trend was identifiable: the late winter and the early spring were becoming warmer, while the summer and early autumn became cooler. The average temperature in Bremen was 8.3606 deg C at that time. Additionally we combined the newly discovered Heinrich W. M. Olbers temperature data and the Heinemann and Bätjer data to see whether there are great differences between these two time series. Although the temperatures of Heinrich W. M. Olbers are in general cooler than the Heinemann and Bätjer data they fit together.

Communication Project for development: 25 years of experience in andean rural communities in Ecuador

IThis paper analyses communication for development from a new perspective: the project in its broader and most genuine sense, as an instrument for changing current reality. This is examined from both its theoretical and practical implementation side. Knowledge/action binomial as a two-way relationship is one of the basis of the project cycle. It allows for better knowing the reality that the project itself (what constitutes the action) is intended to improve. Besides that, this knowledge/action binomial also offers new knowledge that nourishes future actions (projects). From a project based communication perspective, the project nourishes the knowledge, which leads to a transformative action. Reflecting about the action is a new knowledge source whose adoption by the community is eased by the communication process. Radio Mensaje project among the indigenous Andean communities in Cayambe (Ecuador) was born and also developed within this approach, supporting the collaborative participation in project management. This leads to the development process which is described in this case study.

Short-term response of the Ca cycle of a montane forest in Ecuador to low experimental CaCl2 additions

The tropical montane forests of the E Andean cordillera in Ecuador receive episodic Sahara- dust inputs particularly increasing Ca deposition. We added CaCl2 to isolate the effect of Ca deposition by Sahara dust to tropical montane forest from the simultaneously occurring pH effect. We examined components of the Ca cycle at four control plots and four plots with added Ca (2 × 5 kg ha?1 Ca annually as CaCl2) in a random arrangement. Between August 2007 and December 2009 (four applications of Ca), we determined Ca concentrations and fluxes in litter leachate, mineral soil solution (0.15 and 0.30 m depths), throughfall, and fine litterfall and Al con- centrations and speciation in soil solutions. After 1 y of Ca addition, we assessed fine-root bio- mass, leaf area, and tree growth. Only < 3% of the applied Ca leached below the acid organic layer (pH 3.5?4.8). The added CaCl2 did not change electrical conductivity in the root zone after 2 y. In the second year of fertilization, Ca retention in the canopy of the Ca treatment tended to decrease relative to the control. After 2 y, 21% of the applied Ca was recycled to soil with throughfall and litterfall. One year after the first Ca addition, fine-root biomass had decreased significantly. Decreasing fine-root biomass might be attributed to a direct or an indirect beneficial effect of Ca on the soil decomposer community. Because of almost complete association of Al with dissolved organic matter and high free Ca2+ : Al3+ activity ratios in solution of all plots, Al toxicity was unlikely. We conclude that the added Ca was retained in the system and had benefi- cial effects on some plants.

Youth participation in development planning: case study of Sayausí (Rural Parish) Cuenca-Ecuador

Young people now represent the highest percentage of the world population. Soon, they will be seniors and they will take decisions for a more orderly and equitable world. For this reason, the participation of young people in development planning is very important and many countries are trying to promote it through various measures. This article analyzes the trajectory of youth participation in the Latin American region and specifically the profile of youth participation in Ecuador, country in which the Constitution recognizes the strategic role of youth in development. The case study of Sayausí rural parish in canton Cuenca is analyzed, through surveys, interviews and an Empowerment Evaluation workshop to young people and decentralized government. The results obtained allow to propose strategies to help improve the participation of youth in the community.

Guidelines of natural zeolites characterization for acid mine drainage treatment. Case study Guayaquil, Ecuador

Zeolites constitute one of the less common groups of tectosilicates. Zeoli1es with pores between -2 to 10 A in their structures have strong sorption capacity and are widely used in industrial and municipal operations to eliminate toxic substances. One of the major environmental problems in the mining activity is the treating of acid mine drainage. In this context, it is very important to search alternatives to manage this challenge. One feasible alternative is using zeolitic tuffs. The results of the physical-chemical characterization of zeolitic tuffs are the c1ue lo continue or not with deeper analysis and tests 01 acid mine drainage treatments. The guidelines to reach this purpose are the main goal of this work. Zeolite 1uff samples (named as XB_01 and XB_02) studied in this work were laken rn the Late Cretaceous Coastal Cayo Arch Ecuador, specifically in the Guaraguao River, showing the most important characteristics of heulandite zeolitic tuffs. X-ray powder diffraction (XRD) tests were developed in order to confirm that the samples belong to the heulandite-type zeoli1ic tuffs. Additionally, Thermogravimetric analysis (TG), Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and X-ray fluorescence (XRF) of the samples was necessary in order to define the Si/Al ratio and the main mineralogical phases. The XB_01 sample shows a higher ratio Si/Al than XB_02 sample. The cation exchange capacity est was the fundamental step to define the potentiality of the zeolite to use in acid mine drainage treatment Three methodologies were employed to determine the cation exchange capacity. The Cuban standard 626 and the ammonium exchange methodologies reflect results more consistent with each other. This is the starting point to continue with deeper studies such as breakthrough curves for heavy metal ions found in acid mine waters.

Journal concerning the bequest and division of James Winthrop's personal library, 1822-1826

As described in the above biographical note, Winthrop bequeathed most of his library – including his father John Winthrop's books – to the newly established Allegheny College in Pennsylvania. All the books in his library did not go to Allegheny, though, and Winthrop bequeathed over 500 books to two individuals, Thaddeus Mason Harris and Harriet H. Peck. This paper-bound journal contains three lists: one list of all the books which were part of this bequest, with notations indicating their financial value; another list of "Mrs. Peck's part in the division of the legacy" (i.e. the books she selected); and another list of "TM Harris's part of Judge Winthrop's Legacy" (the books he selected). The lists indicate that Peck and Harris chose books from the library on February 3, 1822, and that the few books which remained afterwards were sold by Deacon Hilliard and the profits returned to Peck and Harris.
