Evaluation of Phytochemicals and Antioxidant Properties of Leaves, Fruits and Stems of Ficus deltoidea Plant Extract

Annals of biological research (2017)

Usha Kumari R Ayyappadhas Dhanalekshmi UM

The fundamental mechanism underlying a number of human neurodegenerative disorders, diabetes, inflammation, viral infections, autoimmune pathologies and digestive system disorders due to free radicals or reactive oxygen species (ROS). World is blessed with mammoth biodiversity resources, but overwhelmed with several diseases, including those with ROS as the etiological factor. In the present study, the antioxidant activity, total phenolic and flavonoids content of different parts of the plant F. deltoidea, collected from three different areas in Malaysia has been evaluated. Plant extract exhibited strong antioxidant activity. Methanolic extract of F. deltoidea possess more antioxidant principles than aqueous extracts. Among the three sources, F. deltoidea 1 (FD1) possess higher antioxidant activity than the others [FD2 and FD3]. In the present study, we discovered that fruits of F. deltoidea contain more antioxidant principles and free radical scavenging activity and the effects are significantly comparable with standard antioxidants

Cyst nematode, Heterodera oryzicola, on rice in Kerala I. Estimation of loss in rice due to H. oryzicola infestation, in field conditions

Indian Journal Of Nematology (1981)

Usha Kumari K. John Kuriyan

The extent of crop loss caused by cyst nematode, H. oryzicola at different levels of inoculm in rice variety, Triveni, was estimated in a field experiment. It was found that the extent of damage caused to the crop increased with the increase of inoculm levels of 6000, 9000, 12000 and 18000 larvae per sq.m. There was a reduction of 4.39 to 7.65% in the height of the plant, 19.38 to 28.51% in the number of tillers, 10.07 to 28.13% in the number of leaves, 7.36 to 17.10% in the length of ear head, 11.62 to 35.36% in the weight of shoot, 13.76 to 43.37% in the root weight, 7.32 to 28.62% in yield per plot of 1 sq.m. and 7.75 to 36.28% in grain weight per plot of 1 sq.m. over the control. The yield loss per plant was 16.83 to 35.76% and 20.65 to 41.91% in grain weight per plant. There was a correspoilding increase of cyst nematode population and cysts in soil and plant also. The reduction in growth and yield characters of the rice plant was maximum at the highest level of inoculum, showing that the more the nematode population, the more the damage to the plant.

Response of zinc and boron sprays on growth and yield of Aonla (Emblica officinalis Gaertn) cv. Chakiya

Journal of Pharmacognosy and Phytochemistry (2019)

Goutam Jangid Goutam Mandal Usha Kumari

An experiment was conducted during 2016-17 at Department of Horticulture and Post Harvest technology, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal on eight years old aonla trees, to study the effect of foliar application of Zn and B singly and in combinations on the growth and yield of aonla cv. Chakiya, revealed that fruit retention, fruit size (length and breadth), fruit weight, pulp weight, stone weight, pulp thickness and yield were maximized when foliar spray was done with Borax 0.50% + ZnSO4 0.60%.

3-D Triangulation From One Landmark

Larry E. Banta Usha Kumari

Reliable navigation of mobile robots demands that the machine be able to extract location information from its environment, Numerous researchers have used machine vision to follow road edges, to read specialty designed signposts or to triangulate position from the sighting of multiple landmarks. This paper describes a method for position estimation based on monocular vision and triangulation from self-motion. The method is computationally simple due to a manipulation of the transforriation mathematics, and does not require the placement of specialty designed signs or landmarks in the environment. "'Natural" landmarks such as comers, light fixtures, or stationary equipment can be used for triangulation. If the position of the landmark is known in some global coordinate frame, the method can be used for fixing the robot's absolute position. The technique can also be used for circumnavigation of obstacles or for other types of "relative" navigation such as docking or close quarters maneuvering. Travel on non-flat surfaces is accounted for by compensation for vehicle pitch and roll. The method requires input from pitch and roll clinometers, pan/tilt position sensors, odometric sensors and the calculation of one position parameter from independent sensors such as ultrasonic range sensors, optical range sensors, a fluxgate compass or another reliable source independent of the vision system. Keywords: mobile robot, navigation, landmark, vision, triangulation.
