Molecular Characterization of Root-Knot Nematode Meloidogyne enterolobii Infesting Guava in Karnataka, India
The root-knot nematode problem in guava is a newly emerging problem in India. A new report of the presence of new invasive species of root-knot nematode Meloidogyne enterolobii is of major concern now. Representative samples collected from five major guava growing districts namely, Bengaluru, Chikkaballapur, Dharwad, Kolar, and Shivamogga of Karnataka state, India were used for molecular characterization using ITS primer and M. enterolobii specific SCAR primer. All the samples confirmed the presence of new invasive species of root-knot nematode (M. enterolobii) in guava orchards located in different parts of Karnataka. Phylogenetic analysis using the maximum likely hood method grouped the eight isolates into two sub-clusters under a single clade. To the best of our knowledge, the present investigation is the first molecular based confirmation of the presence of M. enterolobii in Karnataka.
Chemical and Biological Control Measures against Cumin Wilt Incited by Fusarium oxysporum f. sp. cumini
Wilt of cumin incited by Fusarium oxysporum f. sp. cumini is one of the important disease and a big constraint in successful cultivation. An investigation was made to minimize this disease by use of systemic and non systemic fungicides. All the fungicides significantly inhibited the mycelial growth of Fusarium oxysporum f. sp. cumini as compared to check at 100, 200, 500 ppm concentration. Carbendazim was found significantly superior at 200 and 500 ppm with maximum inhibition of mycelial growth followed by carbendazim+mancozeb. As the concentration of fungicides increased, the inhibition of mycelial growth was also increased and maximum inhibition was observed at 500 ppm concentration. Hexaconazole was least effective. All the fungicides tested as seed dresser, reduced wilt incidence of cumin in both the years and carbendazim was found significantly superior with minimum disease and maximum yield over control followed by carbendazim+mancozeb. Pooled analysis of two years data revealed that the maximum disease control (72.24%) was recorded in the treatment soil application of FYM + seed treatment with Trichoderma with maximum per cent yield increase (218.34) followed by soil application of Neem cake + seed treatment with Trichoderma with (64.33%) disease control and (202.05%) yield increase. The control resulted maximum incidence of wilt (61.06%) with lowest yield (99.25kg/ha) as compared to all other treatments.
Comparative technical-economical evaluation of gasification-based treatment of municipal solid waste
A technical-economic analysis of municipal solid waste (MSW) gasification was carried out in the commune of Chillán, Chile. The MSW production was quantified and characterized in the 2015-2018 period. The percentage characterization of MSW corresponded to organic matter (61 %), other waste (17 %), plastic (10 %), paper and cardboard (8 %) and glass (4 %). In the analysis, the countercurrent fixed-bed gasification technology was selected, due to the simplicity of operation and less difficulty in controlling the operating parameters. Flow diagrams and gasification mass and energy balances were developed incorporating three preliminary processing options for the wet fraction of MSW: biodigestion, drying and pressing, prior to gasification. Total energy efficiencies were 54.2 %, 54.6 %, and 61.4 % respectively. Finally, a preliminary economic analysis was carried out considering income and costs for the three process alternatives. The approximate annual gross profits were estimated at 6,462,000 US $ ∙ year-1 for press-gasification, 6,139,000 US$ year-1 for drying-gasification and 4,600,000 US$ year-1 for biodigestion-gasification.
Allometric Equations For Predicting Biomass Of Young Canarium Tree (Canarium indicum L.) To Handle Climate Change
Canarium tree as a source of food, energy, health and cultural development has been widely discussed but not in terms of biomass content. In general, studies have not been carried out properly regarding its ability to provide environmental services, especially in dealing with climate change. Therefore, this study aims to determine the value of Biomass Expansion Factors (BEFs) and Root to Shoot ratio (R/S). Beside that, to determine the allometric equation for young Canarium to be used in dealing with climate change. This is done through the Monitoring Reporting and Verification (MRV) System under the United Nations Guidelines for Reducing Emissions from Deforestation and Degradation (UN REDD). There were 32 young canaries at seedling and sapling levels aged 9-21 months in the nursery area, with a diameter of 3.4 - 4.9 cm and a height of 1.32 - 2.48 m. Before determining the allometric equation, the classical assumption test is carried out first. Young canaries have R/S value 0.52 and BEF values 1.50. The allometric equation is Y1 = -700,200 + 209.149X1 + 3.922X2 where Y1 = biomass above ground level, X1 = diameter, X2 = height with R squared 0.386. To calculate the total above and below-ground biomass simultaneously, the following 3 steps were carried out: (1) Calculating above-ground biomass using the allometric equation Y1 = -700,200 + 209.149X1 + 3.922X2, (2) calculating below-ground biomass by utilizing R/S value 0.52 and (3) summing above and below-ground biomass.
SLIDING MODE CONTROL FOR TRAJECTORY TRACKING OF DELTA PARALLEL ROBOTS
Building a dynamic model to meet control requirements is a challenging problem. This paper presents a sliding mode control law and proves its stability for parallel robots containing parameter uncertainties and noise. Next, simple and complex dynamic models were built to establish the sliding mode control law. Finally, trajectory errors of the control using two different dynamic models are compared to conclude which model is more suitable.
