Design of an interface of an automatic equalization system

The idea of this project is to create an interface for an automatic equalizer. But first, a general idea of what an equalizer is. The sole purpose of an equalizer is to bring the different frequencies there are on a range, to the desired value. So, the process is done by sending pink noise to a microphone and then seeing, depending on the place’s infrastructure, how the frequencies are affected. An automatic equalizer uses filters to give more or take some dB’s, depending on the desired spectrum. This program already exists, but it is still missing the interface for the user to be able to operate with it. So that is what this project is about, giving the user the easiest interface to interact with to use the program most efficient way. Therefore, one of the main objectives of this project is to simplify the graphic user interface as much as possible. The execution of this project started with the configuration of a Raspberry Pi, which is where the app is being implemented. The second thing that had to be done was the coding of the app, it was done by using Python as the programming language and Tkinter as the graphical library. The results were as desired, the app is very simple and easy to interact with.La idea principal de este proyecto es crear una interfaz para un ecualizador automático. Pero primero, una idea generalizada de lo que un ecualizador es. El objetivo de un ecualizador es llevar ciertas frecuencias a un rango deseado. Este proceso se logra mediante la emisión de un ruido rosa, que dependiendo del lugar donde haya sido reproducido, se verá afectado y así mismo los distintos rangos de frecuencia que lo conforman. Entonces, el ecualizador se encargaría de hacer esta emisión y captura, para luego modificar, de manera automática los valores iniciales a los deseados, estos estarán determinados por uno de los filtros que conforman el ecualizador. Este programa ya existe, fue creado en un proyecto previo a este, pero le falta la interfaz para que pueda ser implementado por un usuario. Y de eso se trata este proyecto. El objetivo es crear una aplicación sencilla y eficaz que permita la rápida interacción con el usuario para poder hacer el proceso de ecualización más rápido. El desarrollo de este proyecto empezó por la configuración de una Raspberry Pi, que es donde se implementará la aplicación. Luego se siguió con la programación del código. Este se programó en Python y con Tkinter como librería gráfica. Los resultados fueron exitosos y la aplicación salió como se esperaba. Sencilla, minimalista y efica

Activity patterns and abundance of a population of Liolaemus espinozai Abdala, 2005 (Iguania: Liolaemidae) in Campo el Arenal, Catamarca, Argentina

Se investigaron los patrones de actividad y abundancias relativas de Liolaemus espinozai, especie endémica de Campo El Arenal (Catamarca, Argentina), entre el año 2007 y 2010. Se contabilizó un total de 1694 avistajes (865 adultos, 620 juveniles y 209 infantiles). Los machos adultos presentan actividad entre octubre y mayo, las hembras entre noviembre y mayo; los juveniles están activos durante todo el año y los infantiles se incorporan a la población a fines de enero o principios de febrero por lo que ésta es la época con mayor abundancia total. Los adultos fueron más abundantes en primavera y verano, en tanto que los juveniles en otoño. Los machos adultos son más abundantes que las hembras durante la primavera (época reproductiva), mientras que éstas lo son en el verano (post-reproductiva). Durante los meses de mayores temperaturas (noviembre a enero) se observa un patrón de actividad bimodal y en los meses restantes la actividad es unimodal. Los patrones de actividad encontrados en adultos machos y hembras, juveniles e infantiles se relacionan de manera diferente con la temperatura, el fotoperíodo y la precipitación.Activity patterns and relative abundances were investigated of Liolaemus espinozai, an endemic species from Campo El Arenal (Catamarca, Argentina), between 2007 and 2010. There were a total of 1694 sightings (865 adults, 620 juveniles and 209 hatchlings). Male adults are active from October, followed by females one month later until May; juveniles are active throughout the year, and hatchlings are added to the population in late January or early February, so this is the time with the greatest total abundance. Adults were more abundant in spring and summer, and juveniles in autumn. Adult males are more abundant than females in spring (breeding season), while these are in the summer (post-reproductive season). The species exhibits a bimodal pattern of activity in the months of higher temperatures, and unimodal in the rest of the months. The different activity patterns found in adult males and females, juveniles and hatchlings are related in a different way with temperature, photoperiod and rainfall.Fil: Cabrera, Maria Paula.

Derivations and loops of some evolution algebras

In this work we study the space of derivations of non-degenerate evolution algebras. We improve some results obtained recently in the literature and, as a consequence, we advance in the description of the derivations for n-dimensional Volterra evolution algebras. In addition, we introduce the notion of loop of an evolution algebra and we analyze under which conditions the set of loops is invariant under change of basisFunding for open access publishing: Universidad Málaga/CBU

The Phycotoxin Domoic Acid as a Potential Factor for Oxidative Alterations Enhanced by Climate Change

Harmful algal blooms (HAB) threaten aquatic and marine ecosystems and wildlife through the creation of hypoxic conditions, and through the toxins they produce. Climate change is creating conditions that increase the impact of HAB on the aquatic ecosystems, rising the frequency of these events. Domoic acid (DA) is a marine phycotoxin produced during HAB of the diatoms Pseudonitzchia sp. It was described that DA causes production of reactive oxygen species (ROS), neurological dysfunction, DNA damage, lipid peroxidation, energy depletion, mitochondrial damage and cell death in animals and humans. However, the information about the effect of this phycotoxin on the non-toxin producing phytoplankton community is scarce or null in relation to oxidative stress measurements. The hypothesis of this opinion article is that DA produced by HAB, might favor the generation of reactive species, that through diffusion to the extracellular environment modifies the oxidative metabolism of non-toxin-producing marine phytoplankton. This feature opens the possibility that not only the phytoplankton community, but also the rest of the food web might be deeply affected if, due to global warming, HAB magnitude and frequency continue increasing.Fil: Cabrera, Joaquin.

Oxidative effects of the harmful algal blooms on primary organisms of the food web

Degraded water quality from nutrient pollution, physical, biological, and other chemical factors contributes to the development and persistence of many harmful algal blooms (HABs). The complex dynamics of the HABs is a challenge to marine ecosystems for the toxic effects reported. The consequences include fish, bird, and mammal mortality, respiratory or digestive tract problems, memory loss, seizures, lesions and skin irritation in many organisms. This review is intended to briefly summarize the recent reported information on harmful marine toxin deleterious effects over the primary organisms of the food web, namely algae, zooplankton and invertebrates. Special focus is made on oxidative stress status of cells and tissues. Even though in situ field research is less controlled than laboratory studies, in which the organisms are directly exposed to the toxins under consideration, both types of approaches are required to fully understand such a complex scenario. On top of that, the contribution of the increasing water temperatures in thesea, as a consequence of the global climate change, will be addressed as a topic for further studies, to evaluate the effect on regulating algal growth, species composition, trophic structure, metabolic stress and function of aquatic ecosystems.Fil: Cabrera, Joaquin.

Identification of Leukotoxin and other vaccine candidate proteins in a Mannheimia haemolytica commercial antigen

AbstractBovine Respiratory Disease is the most costly disease that affects beef and dairy cattle industry. Its etiology is multifactorial, arising from predisposing environmental stress conditions as well as the action of several different respiratory pathogens. This situation has hindered the development of effective control strategies. Although different type of vaccines are available, many currently marketed vaccines are based on inactivated cultures of the main viral and bacterial agents involved in this pathology. The molecular composition of commercial veterinary vaccines is a critical issue. The present work aims to define at the proteomic level the most relevant valence of a line of commercial respiratory vaccines widely used in Central and South America. Since Mannheimia haemolytica is responsible for most of the disease associated morbid-mortality, we focused on the main proteins secreted by this pathogen, in particular Leukotoxin A, its main virulence factor. By Western blot analysis and mass spectrometry, Leukotoxin A was identified as a major component of M. haemolytica culture supernatants. We also identified other ten M. haemolytica proteins, including outer membrane proteins, periplasmic transmembrane solute transporters and iron binding proteins, which are relevant to achieve protective immunity against the pathogen. This work allowed a detailed molecular characterization of this vaccine component, providing evidence of its quality and efficacy. Furthermore, our results contributed to the identification of several proteins of interest as subunit vaccine candidates
