Cotton quality, a major factor determining both cotton profitability and marketability, is affected by not only the overall quantity of but also the type of the foreign matter. Although current commercial instruments can measure the overall amount of the foreign matter, no instrument can differentiate various types of foreign matter. The goal of this study was to develop a hyperspectral imaging...

Arthropod pests are among the major problems in soybean production and regular field sampling is required as a basis for decision-making control. However, traditional methods laborious time-consuming. Therefore, our goal to evaluate hyperspectral remote sensing tool establish reflectance patterns from plants infested by various densities of two species stinkbugs (Euschistus heros Diceraeus mela...

The performance of the gutter brooms sweeping system was studied by conducting an experimental test. test is carried out operating a sweeper to sweep plastic, paper, and leaf waste. results show that at broom rotation speed 150,6 rpm, plastic obtained 100% success rate with three settings for height broom, while waste position ± 0 mm touching road surface paper 15 pressing surface. comprehensiv...

ABSTRACT The witches'-broom disease, caused by the basidiomycete Crinipellis perniciosa, is the most limiting factor for cacao cultivation in Brazil. Trichoderma stromaticum is a mycoparasite of the witches'-broom pathogen of cacao that is currently being applied in the field to manage the disease in Bahia State, Brazil. In this work, molecular and traditional methods were used to study the gen...

The unmanned aerial vehicle (UAV)-borne hyperspectral imaging system has the advantages of high spatial resolution, flexible operation, under-cloud flying, and easy cooperation with ground synchronous tests. Because this platform often flies under clouds, variations in solar illumination lead to irradiance inconsistency between different rows images (HSIs). This causes errors radiation correcti...

Montane regions worldwide have experienced relatively low plant invasion rates, a trend attributed to increased climatic severity, low rates of disturbance, and reduced propagule pressure relative to lowlands. Manipulative experiments at elevations above the invasive range of non-native species can clarify the relative contributions of these mechanisms to montane invasion resistance, yet such e...

In the present study 14 bacterial strains were isolated from root nodule of Crotolaria junceae L. from 4 different sites of Assam. The isolates were investigated for their morphological characteristics. Three different confirmatory tests were performed with the isolates. The isolates were also investigated for their biochemical characteristics and compared with biochemical characteristics of re...

The quantum density of states of the Henon-Heiles potential displays a pronounced beating pattern. This has been explained by the interference of three isolated classical periodic orbits with nearby actions and periods. A singular magnetic flux line, passing through the origin, drastically alters the beats even though the classical Lagrangian equations of motion remain unchanged. Some of the ch...
