The effects of different types of noise on human heart rate

In an industrial environment, chronic noise exposure is assumed to affect human heart rate. If this is true, people who are more sensitive to noise will run a higher risk of incurring cardiovascular diseases. Sixteen healthy experimental subjects, all with normal hearing, eight males and eight females, were exposed to five different types of pink and white noise at 60, 70, 80, and 85 dBA in order to determine if any relationship exists between the heart rate and sex. Each individual was exposed for a maximum of thirty seconds for each type and level of noise. Audiometric tests were given to subjects in order to measure their hearing sensitivity (threshold) before and after the experiment. This study provides valuable information towards understanding if autonomic responses are higher in people who consider themselves sensitive to noise, and in determining if sex plays a role on any effects noise may exert on heart rate

Arriba durante la Transición española: el abandono de su función propagandística con respecto al Gobierno

During the Spanish transition, there were political, social and ideological, but also journalistic updates in the country, which caused the newspaper Arriba, founded by ‘Falange Española’ and assimilated as a propaganda organ by Franco’s regime during the dictatorship, evolved during the Spanish transition. Due to the incoming ideologies in its newsroom, the newspaper went from supporting the government after Caudillo’s death (November, 1975), to criticize it at the end of the period, during the referendum of the Constitution (December, 1978).Durante la transición española, se produjeron cambios políticos, sociales, ideológicos y periodísticos en el país que contribuyeron a que el diario Arriba, fundado por Falange Española y asimilado como órgano de propaganda por el régimen franquista durante la dictadura, evolucionara considerablemente. Pasó, así, gracias a la presencia de diferentes ideologías en su redacción, del apoyo al Gobierno, aún muy presente tras la muerte de Franco (noviembre de 1975), a la crítica hacia el mismo al fin de este período, el referéndum de la Constitución (diciembre de 1978)

Animal Identification and Records Monitoring Tool using RFID (AIRMTR)

This study was conducted to design, develop and initially implement the Animal Identification and Records Monitoring Tool using RFID. Specifically, it identified the problems encountered in conducting Manual Tagging for Animal Clinic; the appropriate features of the tool that can be developed to address the problems encountered, and the respondents’ level of acceptance of the user toward the developed tool in termsof functionality, reliability, usability, and performance. The research used the qualitative-quantitative research method that utilized a researcher-made questionnaire and interview questions. The respondents of the studywere one (1) Animal Care Specialist representative, one (1) Pretty Paws representative, five (5) veterinarian representatives and eighty (80) pet owners from different places. The problems encountered in conducting tagging for animal clinic were traditional animal tag may cause death to some animals; animal diseases and injuries by animal tagging; duplication and confusion in using animal tagging; and difficulty in maintainingrecords of vaccination, medication health check-ups using animal tagging. The appropriate features of the tool that can be developed to address the problems encountered were: RFID can make the process of animal tagging faster and easier; and online scheduling and identification of pets in pet clinics are more convenient to use for both pet owners and veterinarians rather than the manual process. The respondents’ ratings for Animal Identification and Record Monitoring Tool using RFID were highly acceptable in terms of functionality (4.62); reliability (4.52); usability (4.68); and performance (4.59). The government agencies may suggest that animals should be tagged using the developed system for monitoring purposes. Further research on Internet controlleddevices may be conducted other than stand-alone offline software programs. This study may also be developed considering the following features: UHF as a tracking device for animals; individual registered users to make page where the client can edit, rate and price; displaying hex value using LCD; access to the shop’s system to bevalidated; contraction number of the project with logo and clinic’s validation.

Codes for channels with segmented edits

We consider insertion and deletion channels with the additional assumption that the channel input sequence is implicitly divided into segments such that at most one edit can occur within a segment. We further assume that there are no segment markers in the received sequence. We propose code constructions for the segmented deletion, segmented insertion, and segmented insertion-deletion channels based on subsets of VT codes chosen with pre-determined prefixes and/or suffixes. The proposed codes are zero-error, can be decoded segment-by-segment, and their rate scaling as the segment length increases is the same as that of the maximal code.This work has been funded in part by the European Research Council under ERC grant agreement 259663 and by the Spanish Ministry of Economy and Competitiveness under grant TEC2016-78434-C3-1-R

Evaluación de la protección conseguida en la cuenca de un torrente de montaña ante los daños causados por eventos torrenciales mediante su restauración hidrológico-forestal. Cuenca del torrente de Arratiecho en el Pirineo Aragonés, España.

La demanda continua e insistente de innovación en el ámbito cotidiano, nos hace perder la perspectiva de análisis cuando los procesos requieren un periodo prolongado para resolverse. Esto ocurre con los bosques ubicados en cuencas vertientes a torrentes de montaña, que tienen su origen en la restauración hidrológico-forestal llevada a cabo en las mismas, como complemento de los trabajos de corrección hidráulica efectuados en los torrentes, para controlar los procesos de erosión, inundaciones y aterramientos, desencadenados en diferentes zonas de la cuenca, cuando se dinamizan en ella los ciclos del agua y de los sedimentos a causa de los aguaceros o de la repentina fusión del manto de nieve. La cuenca vertiente al torrente de Arratiecho, situada en el municipio de Biescas, Pirineo Aragonés, fue restaurada y el barranco corregido entre 1903-05; para evitar su desertificación ante la erosión generalizada que sufría la misma, frenar el deslizamiento de una ladera morrénica y reducir los efectos de las inundaciones y aterramientos en su cono de sedimentación, donde se ubican los terrenos más fértiles y le atraviesa la carretera nacional N-260. Se comentan los trabajos realizados y los resultados obtenidos un siglo después, atendiendo especialmente a la evolución de las reforestaciones, siguiendo los criterios utilizados en el análisis de los bosques protectores

Marine microalgae as a potential source of single cell protein (SCP)

[Abstract] The marine microalgae Tetraselmis suecica, Isochrysis galbana, Dunaliella tertiolecta and Chlorella stigmatophora are good biological sources of single cell protein (SCP). Protein content accounts for 39.12%–54.20% of the dry matter, D. tertiolecta having the highest. Lysine values are between 3.67 and 4.52 g/100 g of protein, and thus are higher than those for freshwater species. The total nucleic acid content is less than 7% of the dry matter; this value is definitely lower than that for yeasts or bacteria, commonly used as SCP sources. Amino acid profiles of the four species are very similar and comparable to the FAO reference protein, buth with a low content of methionine and cystine and a high content of lysine. The MEAA indices are between 81 and 84.98, without significant differences among the four species. Marine microalgae can be used as a potential SCP source

Volcanic constraints on the unzipping of Africa from South America: Insights from new geochronological controls along the Angola margin

The breakup of Africa from South America is associated with the emplacement of the Paraná-Etendeka flood basalt province from around 134 Ma and the Tristan da Cunha plume. Yet many additional volcanic events occur that are younger than the main pulse of the Paraná-Etendeka and straddle the rift to drift phases of the main breakup. This contribution reports on new geochronological constraints from the Angolan part of the African Margin. Three coastal and one inland section have been sampled stretching across some 400 Km, with 39Ar/40Ar, U-Pb and Palaeontology used to provide age constraints. Ages from the new data range from ~100 to 81 Ma, with three main events (cr. 100, 91 and 82-81 Ma). Volcanic events are occurring within the Early to Late Cretaceous, along this part of the margin with a general younging towards Namibia. With the constraints of additional age information both onshore and offshore Angola, a clear younging trend at the early stages of rift to drift is recorded in the volcanic events that unzip from North to South. Similar age volcanic events are reported from the Brazilian side of the conjugate margin, and highlight the need to fully incorporate these relatively low volume volcanic pulses into the plate tectonic breakup models of the South Atlantic Margin
