GENETIC DIVERSITY, HERITABILITY AND CORRELATION BETWEEN LOCAL CULTIVARS OF UPLAND RICE
No full textPaddy is one of the important cereal crops as food a main food for a third of the world\u27s population, including Asia. Production of paddy rice plants can be improved through plant genetic improvement. The ebjective of this study was examine the genetic diversity, heritability, and correlation between the characteristics of several local upland rice cultivars. This study was carried out in Tamarenja Village, Sindue District, Donggala Regency, Central Sulawesi Province. It was began in May to October 2018. A Randomized Block Design with eight cultivars as a genotypic treatment and reapeted three times was used in this study. There were 24 trial plots in total. Variables observed included plant height, number of leaves, length of leaves, number of tillers, number of productive tillers, age of panicle exit, panicle length, harvest age, number of seeds per panicle, seed length, seed diameter, weight of 100 seeds, and total yield. The results showed that the genetic influences were more dominant than the environment on all observed variables except the weight of 100 seeds and seed diameter. The number of seeds per panicle, the number of tillers and the number of productive tillers were traits that have a high value on heritability and genetic progress. Panicle length, seed diameter and weight of 100 seeds were characteristics that have a high genetic correlation coefficient on upland rice yields. The weight of 100 seeds has a direct influence and high genetic correlation to the results so that it can be used as a direct selection criterion to increase upland rice yields

Curve Tilting With Nonlinear Model Predictive Control for Enhancing Motion Comfort
No full textThe benefits of automated driving can only be fully realized if the occupants are protected from motion sickness. Active suspensions hold the potential to raise the comfort level in automated passenger vehicles by enabling new functionalities in chassis control. One example is to actively lean the vehicle body toward the center of the corner to counteract the inertial lateral acceleration. Commonly known as curve tilting, the concept is deemed effective in reducing postural disturbance on the occupants and the visual-vestibular conflict when the occupants do not have an external view. We present in this article a nonlinear model predictive control (NMPC) method for the curve tilting functionality. The controller incorporates the nonlinear suspension forces in the prediction model to help achieve high tracking accuracy near the physical limit of the suspension system. The optimization process is accelerated with an explicit initialization method that is based on piecewise-affine (PWA) modeling and offline solution to an alternative optimal control problem (OCP). The controller is able to operate at 20 Hz in a hardware-in-the-loop (HIL) setup. Given sufficient computational resources, we observe a significant reduction in the lateral acceleration sensed by the passenger over a vehicle with passive suspensions, namely, by 46.5%, 25.4%, and 25.4% in the highway, rural, and urban driving scenarios, respectively. The NMPC also outperforms the baseline proportional-integral-derivative (PID) controller by achieving lower tracking error, namely, by 12.9%, 16.4%, and 38.0% in the aforementioned scenarios.Intelligent VehiclesTeam Tamas Keviczk
Observation of currentless redox reactions on surface of water jet immersed in low-pressure plasma
No full textWe investigated oxidation-reduction reactions on the surface of water jet immersed in a low-pressure inductively coupled helium plasma. The electrical potential of the water jet was floating, and no electrical current was supplied from the plasma to the water jet. We observed the productions of molecular hydrogen and molecular oxygen. We also observed negligible consumption of water vapor in the gas phase, suggesting that the productions of hydrogen and oxygen were not owing to the conversion from water vapor. When we employed silver nitrate solution instead of pure water, we observed the decrease in the production rate of hydrogen, whereas the production rate of oxygen was the same in pure water and silver nitrate solution. In addition, we found the synthesis of silver particulates in the silver nitrate solution, indicating the competition between the reductions of H+ and Ag+. Thus, the experimental results reveal the simultaneous oxidation and reduction at the same plasma-liquid interface
Insecticidal effect of diatomaceous earth and pirimiphos-methyl against phosphine-susceptible and phosphine-resistant populations of two stored product beetle species
No full textIn the present study, we evaluated the insecticidal efficacy of diatomaceous earth (DE) and pirimiphos-methyl for the control of phosphine-susceptible and phosphine-resistant populations of Tribolium castaneum (Herbst) and Sitophilus oryzae (L.). Insecticides were applied on wheat or rice at two doses: DE was applied at 1000 and 2000 ppm and pirimiphos-methyl at 1 and 5 ppm. Adult mortality was measured after 7, 14, and 21 days of exposure, and progeny production capacity on the treated substrates was evaluated 65 days later. For T. castaneum, we found that DE, at 2000 ppm, was able to provide 100% control of two of the three populations tested, while for the third population mortality reached only 84%. Similarly, there were differences in mortality levels after exposure to DE-treated grains between the two S. oryzae populations tested. At 1 ppm, pirimiphos-methyl was not effective for any of the T. castaneum populations tested, but complete mortality was recorded for all populations at 5 ppm. In general, populations of S. oryzae were more susceptible than those of T. castaneum, for both commodities. Our data indicate that both insecticides can be used with success in phosphine resistance management programs, but there are populations of a given species that may be less susceptible, which constitutes a preliminary screening essential. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature
Population growth of stored product insects on wheat containing wheat bugs
No full textIn the present study we examined the effect of the presence of wheat bugs (Eurygaster spp. and Aelia spp.) on wheat on the mortality, progeny production and infestation patterns of three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) and Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 ± 5% relative humidity (r.h.) and continuous darkness), and 20 adults of each stored product insect species were placed in plastic vials (3 cm in diameter, 8 cm in height) with wheat that contained different numbers of wheat bugs (1, 2, 3 or 5 adults). In general, stored product insect mortality was not affected by the presence of wheat bugs, in most of the combinations examined. In most of the cases, mortality of T. granarium was higher on wheat which contained Eurygaster that wheat containing Aelia, while progeny production of S. oryzae was also affected by the presence of wheat bugs. Frass production for all combinations was similar, but greater frass production occurred by all combinations of R. dominica with Aelia. Overall, the presence of wheat bugs could affect the survival and the progeny production of both S. oryzae and R. dominica. In general, our results showed that beetle longevity and fecundity can be affected by the presence of wheat bugs that are likely to be present in stored grains after harvest.

Population-Mediated Responses of Lasioderma serricorne (Coleoptera: Anobiidae) to Different Diagnostic Protocols for Phosphine Efficacy
No full textWe evaluated different monitoring protocols for phosphine resistance in adults of three populations of the cigarette beetle, Lasioderma serricorne (F.), termed LB, 2KT, and E1. The protocols evaluated were as follows: 1) the Food and Agriculture Organization (FAO) bioassay, i.e., the exposure at 30 ppm of phosphine for 20 h, 2) the dose response, based on the exposure at 50-1,000 ppm of phosphine for 3 d, 3) the Cooperation Center for Scientific Research Relative to Tobacco (CORESTA) bioassay, which is based on exposures of 4 d at 200 ppm, and, if there are surviving individuals, of 10 d at 700 ppm, and 4) Detia Degesch Phosphine Tolerance Test Kit (DDPTTK), based on the evaluation of the exposed insects for short intervals of exposure (in our case 90 min) at 3,000 ppm. From the populations tested, E1 indicated the highest survival in the FAO bioassay. Moreover, adults of this population were able to survive at 200 ppm, in the dose response, in contrast with the other populations. However, both 2KT and E1 gave similar results in DDPTTK, but only E1 had survivors after 7 d postexposure. Finally, only adults of E1 survived the CORESTA bioassay for 200 ppm and 4 d, but not for 700 ppm and 10 d. Our results show that, at least in the range of the populations tested here, there are some trends that are comparable among the different diagnostics for L. serricorne, which can be utilized further in designing a widely adopted standardized protocol. © 2021 The Author(s)
