Sunflower nutrition irrigated with domestic sewage treated

This study aimed to evaluate the nutritional status of the sunflower (Helianthus annus L.) irrigated with domestic effluents. The study was performed in a pilot sewage treatment plant, where the treatments were composed by the combination of two factors: types of water (A1 - effluent treated by UASB reactor; A2 – effluent treated with digester decant and anaerobic filtering; A3 – effluent treated with anaerobic filtering; and A4 – water supply) and irrigation depths (L1 - equal to the crop evapotranspiration (ETc) and L2 – 1.2 ETc. The experimental design was in randomized blocks, in a 4 x 2 factorial scheme, with four replications. At 96 days after sowing, the leaves, capitulum, and achenes were collected for the concentration evaluation of N, P, K, Ca, Mg and S. The analyses of variance were performed based on the concentration of the nutrients in the respective organs; when significant, they were analyzed by orthogonal contrasts. The sunflower nutritional status was influenced by the types of treatment for the domestic sewage, especially regarding N, Ca and S, and by the irrigation depths; the sunflower crop presented a better nutritional balance when irrigated with treated domestic effluents; with the application of the water supply only, the nutritional supply of the P and S, is necessary.This study aimed to evaluate the nutritional status of the sunflower (Helianthus annus L.) irrigated with domestic effluents.

Development of a Seismic Risk Model for Northern Algeria

A collaborative effort was made within the scope of the EU project ITERATE to develop a web-based tool for large-scale probabilistic assessment intended to enable Algerian stakeholders to understand and calculate seismic risk though the convolution of hazard, exposure and vulnerability. A great amount of information was collected, organized and processed to determine the characteristics of the Northern Algerian built inventory (buildings and bridges) in terms of quantity, location, typology and structural behavior, using the city of Blida as pilot case-study. Furthermore, the vulnerability of the inventory was evaluated through the development of fragility curves, based on the observed behavior of a great number of nonlinear structural models under the effect of multiple earthquake records, accounting for epistemic and aleatory uncertainties. The developed exposure and vulnerability models, along with an updated seismic hazard model were loaded to a specifically developed web application which allows the probabilistic evaluation of seismic event scenarios, as well as automated predictions in terms of human and economic losses.This research has been carried out under the project ECHO/SUB/2016/740181/PREV23 – ITERATE – Improved Tools for Disaster Risk Mitigation in Algeria.

The automatic detection subsystem

Marques, M. M., Lobo, V., Aguiar, A. P., Silva, J. E., de Sousa, J. B., Nunes, M. D. F., Ribeiro, R. A., Bernardino, A., Cruz, G., & Marques, J. S. (2021). An unmanned aircraft system for maritime operations: The automatic detection subsystem. Marine Technology Society Journal, 55(1), 38-49. https://doi.org/10.4031/MTSJ.55.1.4 --- This work was funded by POFC (Programa Operacional Factores de Competitividade) within the National Strategic Reference Framework (QREN) under grant agreement 2013/034063 (SEAGULL, Project Number 34063).This paper addresses the development of an integrated system to support maritime situation awareness based on unmanned aerial vehicles (UAVs), empha-sizing the role of the automatic detection subsystem. One of the main topics of research in the SEAGULL project was the automatic detection of sea vessels from sensors onboard the UAV, to help human operators in the generation of situational awareness of maritime events such as (a) detection and geo-referencing of oil spills or hazardous and noxious substances, (b) tracking systems (e.g., vessels, ship-wrecks, lifeboats, debris), (c) recognizing behavioral patterns (e.g., vessels rendez-vous, high-speed vessels, atypical patterns of navigation), and (d) monitoring environmental parameters and indicators. We describe a system composed of optical sensors, an embedded computer, communication systems, and a vessel detection algorithm that can run in real time in the embedded UAV hardware and provide to human operators vessel detections with low latency, high precision rates (about 99%), and suitable recalls (>50%), which is comparable to other more computationally intensive state-of-the-art approaches. Field test results, including the detection of lifesavers and multiple vessels in red-green-and-blue (RGB) and thermal images, are presented and discussed.publishersversionpublishe

Interoperability in a Heterogeneous Team of Search and Rescue Robots

Search and rescue missions are complex operations. A disaster scenario is generally unstructured, time‐varying and unpredictable. This poses several challenges for the successful deployment of unmanned technology. The variety of operational scenarios and tasks lead to the need for multiple robots of different types, domains and sizes. A priori planning of the optimal set of assets to be deployed and the definition of their mission objectives are generally not feasible as information only becomes available during mission. The ICARUS project responds to this challenge by developing a heterogeneous team composed by different and complementary robots, dynamically cooperating as an interoperable team. This chapter describes our approach to multi‐robot interoperability, understood as the ability of multiple robots to operate together, in synergy, enabling multiple teams to share data, intelligence and resources, which is the ultimate objective of ICARUS project. It also includes the analysis of the relevant standardization initiatives in multi‐robot multi‐domain systems, our implementation of an interoperability framework and several examples of multi‐robot cooperation of the ICARUS robots in realistic search and rescue missions

Atributos químicos de um Neossolo Regolítico distrófico em função das doses e tempos de aplicação de vinhaça.

A vinhaça é um resíduo proveniente do processo de destilação do álcool, rico em matéria orgânica e nutrientes e, por isso, é muito utilizado para fertirrigação nos próprios canaviais. Entretanto, se aplicado em doses excessivamente altas pode desequilibrar o complexo sortivo do solo e, se descartado indiscriminadamente no solo, pode trazer sérios riscos ao ambiente. Objetivou-se avaliar o efeito de doses crescentes de vinhaça (0; 59; 119; 237 e 474 m3 ha-1) e diferentes tempos de incubação (30 e 60 dias) nos atributos químicos de um Neossolo Regolítico distrófico. Durante o estudo, foram avaliadas as seguintes variáveis: condutividade elétrica do extrato de saturação do solo (CEes), pH e teores de K+ e Na+ trocáveis do solo. Ao final do estudo, foi possível concluir que os tempos de incubação de vinhaça no solo só afetaram significativamente as variáveis estudadas quando foi utilizada a maior dose de tal resíduo. Os teores de K+ e Na+ presentes no solo foram influenciados significativamente em decorrência da aplicação das doses crescentes de vinhaça, entretanto o pH e a CEes foram pouco afetados independente das doses utilizadas deste resíduo. A aplicação das lâminas de lixiviação provocou maior lixiviação de K+ do que Na+ do solo, fato que pode ocasionar a sodicidade do solo em função da aplicação de altas doses de vinhaça

On this and other worlds: Voices from Amazonia

This edited volume offers a collection of twelve interlinear texts reflecting the vast linguistic diversity of Amazonia as well as the rich verbal arts and oral literature traditions of Amazonian peoples. Contributions to the volume come from a variety of geographic regions and represent the Carib, Jê, Tupi, East Tukano, Nadahup, and Pano language families, as well as three linguistic isolates. The selected texts exemplify a variety of narrative styles recounting the origins of constellations, crops, and sacred cemeteries, and of travel to worlds beyond death. We hear tales of tricksters and of encounters between humans and other beings, learn of battles between enemies, and gain insight into history and the indigenous perspective of creation, cordiality and confrontation. The contributions to this volume are the result of research efforts conducted since 2000, and as such, exemplify rapidly expanding investment and interest in documenting native Amazonian voices. They moreover demonstrate the collaborative efforts of linguists, anthropologists, and indigenous leaders, storytellers, and researchers to study and preserve Amazonian languages and cultures. Each chapter offers complete interlinear analysis as well as ample commentary on both linguistic and cultural aspects, appealing to a wide audience, including linguists, historians, anthropologists, and other social scientists. This collection is the first of its type, constituting a significant contribution to focused study of Amazonian linguistic diversity and a relevant addition to our broader knowledge of Amerindian languages and cosmologies
