Fungicide application technology for controlling the sugarcane orange rust

With the epidemic onset of the sugarcane orange rust, fungicide applications of the Strobilurins and Triazoles groups have become necessary in susceptible varieties. This study aimed at evaluating the operational conditions of fungicide application in sugarcane (SP81-3250 variety), in relation to the spray deposition on the upper canopy and the effectiveness of the orange rust control. Treatments consisted of two application volumes (30 L ha-1 or 40 L ha-1) and three nozzle deflection angles (0 º, 90 º or 135 º), plus a ground application at the rate of 200 L ha-1, sprayed with a uniform flat spray nozzle of air induction. The ground application resulted in the smallest and the greatest spray deposition on sugarcane leaves and on the soil, respectively. The aerial application at the rate of 30 L ha-1, sprayed by hollow cone nozzles, at a deflection angle of 135 º, provided the best sugarcane orange rust control. Tecnologia de aplicação de fungicidas no controle da ferrugem alaranjada da cana-de-açúcar -- Com o surgimento epidêmico da ferrugem alaranjada da cana-de-açúcar, aplicações de fungicidas dos grupos químicos Estrobilurinas e Triazóis tornaram-se necessárias para as variedades suscetíveis. Objetivou-se avaliar as condições operacionais de aplicação de fungicidas em cana-de-açúcar (variedade SP81-3250), no que se refere à deposição de calda no dossel superior e à efetividade do controle da ferrugem alaranjada. Os tratamentos consistiram de dois volumes de aplicação (30 L ha-1 ou 40 L ha-1) e três ângulos de deflexão das pontas (0 º, 90 º ou 135 º), além de uma aplicação terrestre à taxa de 200 L ha-1, pulverizada por meio de pontas de jato plano uniforme de indução de ar. A aplicação terrestre resultou na menor e maior deposição nas folhas de cana-de-açúcar e no solo, respectivamente. A aplicação aérea com taxa de 30 L ha-1, pulverizada por pontas de jato cônico vazio, com ângulo de deflexão de 135 º, proporcionou o melhor controle da ferrugem alaranjada da cana-de-açúcar

Probing Metastability at the LHC

Current attempts to understand supersymmetry (susy) breaking are focused on the idea that we are not in the ground state of the universe but, instead, in a metastable state that will ultimately decay to an exactly susy ground state. It is interesting to ask how experiments at the Large Hadron Collider (LHC) will shed light on the properties of this future supersymmetric universe. In particular we ask how we can determine whether this final state has the possibility of supporting atoms and molecules in a susy background.Comment: 4 pages, 1 figure, Summary of Conference talk at Susy09, Northeastern University, June 200

Guest Editorial: Social and human aspects of cyber-physical systems

open6siIn the vision of Industry 4.0, the new industrial revolution is a revolution of cyber-physical systems, of which the Internet of Things forms a key foundation that has a great impact on the way people live, and the way businesses are organised. Cyber-physical systems are often considered feedback systems that integrate computation, networking, and physical processes, and more recently with ‘human-in-the-loop’ as one of the key research topics. The advances in social computing have connected human-inthe-loop in cyber-social systems such as Facebook and Twitter, while their social-physical activities are supported by the cyberphysical systems on or near their bodies and in their interconnected environments. Cyber-physical systems become an integral part of social-cyber-physical systems (SCPS) that weave into the sociotechnical fabric of human society. These hybrid systems, exhibiting both continuous (in physical and social spaces) and discrete (in cyberspaces) dynamic behaviour, give rise to not only new opportunities but also new challenges in designing products and services where human and technical aspects are massively intertwined. This Special Issue aims to present state-of-the-art research attempts and results on the topic of SCPS.openopenHu J.; Liang R.-H.; Shih C.-S.; Catala A.; Marcenaro L.; Osawa H.Hu, J.; Liang, R. -H.; Shih, C. -S.; CATALA MALLOFRE, Andreu; Marcenaro, L.; Osawa, H

Teaming up: from motors to people.

When I reflect on how I became a cell biologist and why I love being one today, one thing that comes to mind is the many terrific collaborations I have had. The science I am most proud of from my graduate and postdoctoral training would not have been possible without working in teams with other scientists. Now, in my own group, much of our best work is being done collaboratively, both within the lab and with other labs. In this essay, I will highlight my experiences working in teams as a trainee, the role teamwork has played in my own research group, and how important I think collaborative science is for the future of biological research

GSU Computer Science Programs to Meet Increased Demand

“We live in a supply and demand society. It is essential for the educational institutions that serve society to be proactive; to be prepared to meet the demands of the future,” explained Dr. Yun-Yau (Steve) Shih, Professor of Computer Science at Governors State University in University Park. Shih and his colleagues at GSU are reviewing and redirecting the computer science degree program offered at the university to reflect the increased demand for degreed computer scientists
