Treated Wastewater Irrigation

The first part of the paper provides a short and non-exhaustive overview of human waste use practices in agriculture and aquaculture mainly in the southern hemisphere. In the second part, institutional settings as well as regulations, strategies and practices of health protection in selected reuse schemes are presented and discussed. The promulgation of new guidelines for health protection in human waste use in the late eighties has led authorities in a number of countries to formulate new or amended national guidelines and to devise the monitoring and control of wastewater treatment and reuse schemes. The third part deals with these aspects and the author presents monitoring schedules for treated wastewater irrigation schemes.

Resumo. O milho é o cereal com maior índice de consumo, tanto industrializado como in natura, atualmente. É o grão com maior volume de produção, sendo o Brasil o terceiro maior produtor, dessa maneira, faz-se necessário uma atenção especial voltada ao monitoramento e controle de certos invasores que comprometem sua produtividade. Dentre as pragas que podem afetar essa produtividade destacamos os percevejos (Hemiptera: Heteroptera), mais especificamente o percevejo-do-milho (Leptoglossus zonatus Dallas), que tem se mostrado uma importante praga para a cultura do milho. O presente trabalho teve por objetivo avaliar a eficiência de armadilhas caseiras do tipo “R. Bianco” na captura desse percevejo. Os experimentos foram conduzidos no Sitio Nossa Senhora Aparecida, localizado no município de Sinop, MT. As armadilhas foram divididas em 10 abertas e 10 fechadas e avaliadas com e sem isca por 20 dias. O delineamento utilizado foi o inteiramente casualizado (DIC) em esquema fatorial 2x2x2 com oito tratamentos e cinco repetições. As armadilhas sem iscas demonstraram maior eficiência, apresentando média superior na captura do percevejo em relação às armadilhas com isca. As armadilhas fechadas, em comparação com as abertas, demonstraram maior eficácia na retenção do inseto. O efeito da borda foi pouco representativo nesse experimento. Portanto, a presença da isca não influenciou na atração do inseto e os tratamentos submetidos ao teste sem isca apresentaram maiores quantidades e maior eficiência na captura de insetos. Levando a crer o efeito de atração do sal pelo percevejo e a localização de cada armadilha pouco influenciou na captura dos insetos.Trap Efficiency “R. Bianco” for Capture the insect Leptoglossus zonatus Dallas (Hemiptera: Coreidae) in Maize CropAbstract. Maize is the cereal with the highest consumption in both industrialized as fresh nowadays. It is the grain with higher volume production, Brazil is the third largest producer, need special attention focused on the monitoring and control of invaders who risk their productivity. Among the pests that can affect the productivity highlight the insects (Hemiptera: Heteroptera), more specifically the bedbugs corn (Leptoglossus zonatus Dallas), which has been an important pest for corn crops. Thus, this study aimed to evaluate the effectiveness of homemade traps R. Bianco in control of this insect. The experiments were conducted in Sitio Nossa Senhora Aparecida, in the municipality of Sinop, MT. Traps were divided into 10 open and 10 closed which were evaluated with and without baits by 20 days. The design was completely randomized (DIC) in a 2x2x2 factorial with eight treatments and five repetitions. Traps without baits showed greater efficiency, with an average higher in catching the bugs regarding the traps with bait. The trap closed as compared with the open, demonstrated greater efficacy in retaining the insect. The effect of edge was little representative in this experiment. Therefore, the presence of bait did not influence the insect attraction and treatments submitted to the bait without test showed higher quantities and more efficient insect capture. Leading us to believe the attraction effect of salt by bedbug and the location of each trap had little influence in the capture of insects.

Transmission Velocity

Quantitative knowledge about which natural and anthropogenic factors influence the global spread of plague remains sparse. We estimated the worldwide spreading velocity of plague during the Third Pandemic, using more than 200 years of extensive human plague case records and genomic data, and analyzed the association of spatiotemporal environmental factors with spreading velocity. Here, we show that two lineages, 2.MED and 1.ORI3, spread significantly faster than others, possibly reflecting differences among strains in transmission mechanisms and virulence. Plague spread fastest in regions with low population density and high proportion of pasture- or forestland, findings that should be taken into account for effective plague monitoring and control. Temperature exhibited a nonlinear, U-shaped association with spread speed, with a minimum around 20 °C, while precipitation showed a positive association. Our results suggest that global warming may accelerate plague spread in warm, tropical regions and that the projected increased precipitation in the Northern Hemisphere may increase plague spread in relevant regions.

The legislative norms for treated wastewater diffuse in terms of nitrogen (N) and phosphorus (P) concentrations are becoming increasingly stringent in the EU region. Compliance with the consent values compelled the water authorities to implement moving bed biofilters (MBFs) for tertiary stage effluent polishing. However, on-site and field surveys reveal that numerous MBF units suffer from non-optimal operational conditions, logistical challenges and irregular monitoring. This makes meeting the N-P criterion quite a challenging and expensive affair. It is therefore important to optimize their day-to-day operations, facilitate access to reliable and real-time status updates, and troubleshoot the failures. In this direction, an "internet-of-things", radio frequency ID (RFID) and cloud based monitoring and control tool, Sand-Cycle, was successfully developed, tested and implemented to monitor MBFs. The current study presents full- scale application of the developed remote control and mote technology at two wastewater treatment works. Sand-Cycle illustrated real-time dashboards indicating performance grading factors viz. in-situ average sand circulation rate, active bed volume and filter homogeneity. This presented clear instructions for detected malfunctions and enabled the operators to optimize the MBF output with limited effort. Further technical and technological advancements of such IoT based setups can actively assist in tackling long-term sustainability and wastewater management issues.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.

A modern dairy farm is a complex biotechnical “man-machine-animal” system, where purposeful human activity concentrates mainly on the control of the “machine” and “animal” subsystems, thus making the whole system ergatic. Increasing the interaction effi ciency of machine subsystems with biological objects (animals) requires an in-depth study of the properties and characteristics of the latter, their behavior, adaptive and refl ex mechanisms that ensure the mutual adaptation of machine and biological subsystems. The paper considers general functionality of the “animal” subsystem, which includes lists of monitored parameters (functions) in pre-weaning, pre-lactation and lactation periods. In a similar way, functionals of the subsystems of the general musculoskeletal development of the animal’s body, respiratory and digestive organs, comfort of the habitat, development and control of the reproductive organs of lactating cows were obtained accompanied with a list of controlled functions and parameters. To carry out a set of research activities in this fi eld, FSAC VIM is planning to carry out a complex project that will increase the levels of automation, digitalization and intellectualization of animal husbandry, provide for comfortable environment, optimal rediced-impact service modes for animals and their extended productive longevity, increased quality of milk and autonomous functioning of individual local biotechnical subsystems.
