Ultra-light disposable radio probes for atmospheric monitoring

Representation of clouds remains a latent ambiguity for weather forecasting and climate models since their characteristics depends on multidisciplinary processes in a wide range of natural scales, from the collision of micron-sized droplets and particles to the thousand-of-meters scale of airflow dynamics. Within the Horizon 2020 Innovative Training Network Cloud-MicroPhysics-Turbulence-Telemetry (ITN-COMPLETE), the development of ultra-small light disposable radio probes for fluctuation-inside-cloudsmonitoring is promoted and financed. Being light-weighted (less than 20 grams), the probes will have a fluid-dynamic behavior to allow them to “float” inside warm clouds after been released by an aircraft or an Unmanned Aerial Vehicle (UAV). Each disposable probe is equipped with compact size microprocessors (presently the first prototype uses Arduino© Nano), controllers and a set of sensors for the measurement of atmospheric parameters such as velocity, acceleration, pressure, temperature and humidity variations. All probes are part of the Internet-of-Things (IoT) world. In fact, while floating, they collect, store and then send the coded information to a base station located at the ground through a dedicated radio transmission link. It is to be noted that long-range communication link (10 km) should be assured with low power consumption technology: a network based on the Long Range Wide Area Network (LoRaWAN© protocol) to connect and exchange data within the end-modules and the base station is the potential adopted solution. As far as possible biocompatible elements within the mini ultra-light radio probes will be used to avoid any environmental pollution

ON THE REALIZATION OF A COMMUNICATION SYSTEM FOR ATMOSPHERIC PROBES BASED ON LORA TECHNOLOGIES: PRELIMINARY MEASUREMENTS AND RESULTS

Characterization of atmospheric properties remains a latent ambiguity for weather forecasting and climate models since their characteristics depends on multidisciplinary processes in a wide range of natural scales. The development of ultra-small light disposable radio probes is important to understand this properties Being light-weighted, the probes will have a fluiddifferent atmospheric layers after been released, thus simulating the behaviour of small particles (e.g. drops). Each disposable probe is equipped with compact size microprocessors (presently the first prototype uses velocity, acceleration, pressure, temperature). The probes collect, store and then send the coded information to a base station located at the ground through a dedicated radio transmission link. It is to be noted that longrange communication link (10 km) should be assured with low power consumption technology: a network -modules and the base station is the potential adopted solution. In order to realize the communication system for the atmospheric probes, some prototypal links and networks have bene realized using the Adafruit Feather 32u4 LoRa Radio RFM95 modules. It is an embedded module, which contains a LoRa transceiver RFM95 and an ATmega32u4 microcontroller. The radio module can be powered using 3.3 volts either by using a micro USB or an external battery and it can transmit from +5 dBm to +20 dBm, which are theoretically enough for the purpose of this study. The present work presents the preliminary measurements made both in indoor and outdoor environment considering differ find the best set of parameters to work in the harsh environment to acquire information about warm clouds and send them to the ground receiver. Particularly detailed measurements have been made in harsh environmental found inside a warm cloud. The measurements techniques and results are presented together with the realization of a first operational prototype of both probes and ground receiver

Feasibility Analysis of a LoRa-Based WSN Using Public Transport

LoRa (Long Range) is a proprietary radio communication technology exploiting license-free frequency bands, allowing low-rate information exchange over long distances with very low power consumption. Conventional environmental monitoring sensors have the disadvantage of being in fixed positions and distributed over wide areas, thus providing measurements with a spatially insufficient level of detail. Since public transport vehicles travel continuously within cities, they are ideal to house portable monitoring systems for environmental pollution and meteorological parameters. The paper presents a feasibility analysis of aWireless Sensor Network (WSN) to collect this information from the vehicles conveying it to a central node for processing. The communication system is realized by deploying a layer-structured, fault-resistant, multi-hop Low Power Wide Area Network (LPWAN) based on the LoRa technology. Both a theoretical study about electromagnetic propagation and network architecture are addressed with consideration of potential practical network realization

After a brief description of the whole project, the realization of the first prototypal transmission system using Adafruit® Feather 32u4 LoRa Radio RFM95 embedded modules is described. First propagation measurements and results are presented

Covid-19 and its repercussion on the nutritional Status and gestational Anemia from sociodemographic-obstetric factors

Introduction: Currently, the impact of COVID-19 on sociodemographic and obstetric factors, linked to nutritional status and anemia in pregnant women, represents a significant change in management and healthcare paradigms. Objectives: To consider a multiple logistic regression model and multiple comparisons (Mann-Whitney U test) based on sociodemographic-obstetric factors, nutritional status and anemia in pregnant women before and during Covid-19. Methods: In this study, 113 medical records of pregnant women attended between November 2019 and April 2020 at a Hospital II-1 in Trujillo, Peru were analyzed. Multiple logistic regression model showed a good fit and allowed to correctly classify most of pregnant women. Results: The covariates; employment situation, obstetric history, nutritional condition and anemia were significant. Differences were observed between sociodemographic factors such as employment status, obstetric factors such as obstetric history, and factors related to nutritional status and clinical symptoms of anemia. Conclusions: The impact of COVID-19 reflected in the relationships between sociodemographic and obstetric factors with nutritional status and the anemia diagnosed in pregnant women treated in a Hospital II-1 in Trujillo, Peru, was evidenced

El paradigma de la investigación científica en el Perú y el canon minero

La presente investigación analiza el paradigma de la investigación científica en el Perú y la Ley del Canon Minero promulgada en julio de 2001, que ha sido modificada cuatro veces. En la investigación, de tipo documental-longitudinal, se ha tomado como referencia la Ley 29289 referida a la Ley de Presupuesto del Sector Público para el Año Fiscal 2009, la misma que establece que los recursos del canon, sobrecanon y regalías mineras no podrán utilizarse, en ningún caso, para el pago de remuneraciones o retribuciones de cualquier índole.El paradigma de toda universidad es hacer investigación, misión que se contempla en el artículo 1º de la Ley Universitaria 23733. Los resultados de la investigación muestran que las investigaciones en las universidades son insuficientes. A ello debemos sumar los problemas de índole político-motivacional que originan la escasa presentación de proyectos de investigación por parte de las universidades públicas con financiamiento del canon; y con la última modificatoria, introducida por la Ley 29626, se retrocede aún más en el apoyo económico asignado anualmente a la universidad.Es tarea del gobierno, de los políticos, de los docentes, de los estudiantes universitarios y de la sociedad- empresa concertar para superar nuestras limitaciones y deficiencias en el tema de investigación.Palabras clave: Ley del Canon Minero, Ley 29289, remuneraciones, investigación, universidades públicas.DOI: http://dx.doi.org/10.21503/CienciayDesarrollo.2012.v15i1.0
