La supervisión de obra puede ser un factor determinante tanto para el éxito, como para el fracaso de un proyecto. Un número grande de problemas estructurales y de servicio en las construcciones no son atribuibles a deficiencias del diseño o de los materiales, sino principalmente, al mal desempeño de la supervisión. El profesional que desempeña el trabajo de supervisor de obra se enfrenta no sólo a problemas de carácter técnico, sino también a conflictos generados por la interacción humana. Además de las competencias necesarias para afrontar los problemas de carácter técnico y humano, el supervisor debe contar con un conjunto de valores y actitudes positivas para un adecuado desempeño de su labor. Para el cumplimiento de sus objetivos, la supervisión debe hacer un uso correcto de los medio de comunicación a su alcance, principalmente de la bitácora de obra.

Entre parques y edificios de altura, sobre un terreno con pendiente natural, se sitúa la Biblioteca Nacional de la República Argentina. La misma se encuentra en el barrio porteño de Recoleta, entre las calles Austria, Agüero, Av. Las Heras y Av. Del Libertador.

En el espacio abierto, en condiciones ideales, el sonido emitido por una fuente se propagará alejándose de la misma en forma radial (esférica) y su intensidad decaerá cuadráticamente, donde el nivel sonoro se reducirá en 6dB cada vez que se duplique la distancia (Figura 1).

La Acústica Arquitectónica estudia los fenómenos vinculados con una propagación adecuada, fiel y funcional del sonido en un recinto, ya sea una sala de concierto o un estudio de grabación. Esto involucra también el problema de la aislación acústica.

The present paper will try to deal with the processing and interpretation of the transformed domain of frequency. An acoustic signal in time can be seen as a signal in the frequency domain just to make your Fourier transform. This change will be more complex the more complex the signal. Once you have the frequency spectrum of the signal, you can evaluate and process everything you want. An example would be, in an acoustic measurement, the interpretation of the insulation level of a material at different frequencies, i. e. which frequencies of the signal spectrum are better absorbed, and on the contrary which frequencies are worse isolated. These frequencies are usually seen as frequency groupings, in the so-called frequency bands, since it is not usual to analyze each frequency individually. Ultimately, an example of digital filtering and processing of an audio file in the MATLAB® program will be made.

La acústica es la ciencia que estudia los diversos aspectos relativos al sonido, particularmente los fenómenos de generación, propagación y recepción de las ondas sonoras en diversos medios, así como su transducción, su percepción y sus variadas aplicaciones tecnológicas. La acústica tiene un carácter fuertemente multidisciplinario, abarcando cuestiones que van desde la física pura hasta la biología y las ciencias sociales.

Bibliographic studies are a useful tool as they provide knowledge of the existing research, which helps guide future studies; they can be used to document patterns of published studies on biodiversity, which in diverse countries can provide valuable information to knowledge about global biodiversity. Oaxaca is the richest Mexican state in bird species. Despite the environmental, sociological and economic importance they have, several authors indicate that further study is needed on them. However it is unclear what is known collectively as the information published so far is scattered. This paper presents the collection of 934 documents dealing with birds in Oaxaca, published in the period 1829-2016 and which were obtained by searching in multiple databases and through the collaboration of many researchers. These documents are classified according to eleven thematic categories: “ecology”, “biogeography and distribution”, “locality”, “biology”, “conservation”, “management”, “reproduction”, “systematics and taxonomy”, “genetics”, “etnoornithology”, and “others”. The publications are also classified according to whether the study is conducted exclusively in Oaxaca or not. The bibliometric analysis shows that there is an increase of studies per year. The least studied topics are “etnoornithology” and” locality”; the most studied, “biogeography and distribution” and “systematics and taxonomy”. The latter two issues are also the most linked in studies that include more than one subject category. Current research topics vary more than those written previously. Only 30% of the published studies deal exclusively in the state. The most common format for publishing are magazines, however, lots are not indexed. The remaining formats for publications are gray literature, so definitely, many publications have little visibility. The paper concludes by proposing certain lines of research in the future. The database created can be accessed in the appendix and electronically via any spreadsheet software. This work was developed within the "Program of travel grants for cooperation development Thesis, (1-4 months) during 2015" attached to the scholarship program of the Polytechnic University of Madrid (UPM). Moreover, it is a part of the project that is under the direction of José Cruz Bojorges Baños, BIRDS OF OAXACA: BIBLIOGRAPHY FOR THE DIAGNOSIS OF THE CURRENT KNOWLEDGE, CUP 2IR1106, held at the Universidad del Mar.
