A low-cost interactive computer program was designed to assist in teaching landscape plant material classes or any other class that could benefit from the use of computer graphics. The program was written in HyperCard to be used on any Macintosh computer. To illustrate the morphology and to assist in learning the terminology required to identify plants, a dichotomous keying system incorporating computer graphics was developed to lead the student through an interactive lesson. In the process of keying out plants, the student encounters the terminology associated with the groups of plants during the lesson. The student is introduced to plant groups, the terminology, and the concept of the classification process in one interactive lesson.

Produce Plant

PlantCrystals are obtained by milling plant material to sizes < 10 µm. Due to the disruption of the plant cells, active compounds are easily released, rendering the PlantCrystal technology an effective and low-cost process for the production of environmentally friendly plant extracts. The extracts can be used to produce phytomedicines, nutritional supplements or cosmetic products. Previous studies could already demonstrate the use of PlantCrystals to improve the antimicrobial or antifungal activity of different plants. This study investigated whether PlantCrystal technology is suitable to produce plant derived formulations with high antioxidant capacity. The study also aimed to identify the most suitable production methods for this. Methods: Various plant materials and parts of plants, i.e., seeds, leaves and flowers, and different methods were employed for the production. PlantCrystals were characterized regarding size, physical stability and antioxidant capacity (AOC). Results: PlantCrystals with particles < 1 µm were produced from the different plant materials. Both production methods, i.e., high-pressure homogenization, bead milling or the combination of both were suitable to obtain PlantCrystals. Nano milling of the plant material greatly affected their AOC and resulted in formulations with distinctly higher AOC when compared to classical extracts. Conclusions: Rendering plant material into small sized particles is highly effective to obtain plant extracts with high biological efficacy.

Information Database

The landscape plants that exist on the Alabama A&M University, Normal, campus are readily accessible for a plant identification and use course. Managing location, health, and cultivar information is critical to optimizing this resource. As a classroom assignment, campus plants were inventoried; entered into FileMaker Pro 2.1, a relational database manager; characterized; and assigned locations on campus. The campus map was scanned using a Microtek Scanmaker IIxe and the image was imported into MacDraw II. A symbol library, which included symbols for trees, shrubs, and groundcovers, was developed by scanning hand-drawn images and then importing them into MacPaint. These bit-mapped images were duplicated as often as necessary and placed in appropriate locations on the campus map in MacDraw II. Students were exposed to landscape plant materials, database managers, and computer graphics capabilities. This approach has other advantages: database information can be easily coordinated with physical location, plants can be sorted based on their characteristics, and information can be routinely and easily revised and updated. The database is used in the landscape plant materials class as a teaching tool and for self-guided tours.

In teaching a course in landscape plant materials, the landscape plants which exist on campus are an important and accessible resource. Management of location, health. and cultivar information is critical to optimizing this resource. As a classroom assignment, campus plant materials were inventoried, entered into FileMaker Pro 2.1, a database manager, characterized and assigned locations. The campus map was scanned using a Microtek ScanMaker IIXE and the image imported into MacDraw II. A symbol library, which included symbols for trees, shrubs, and groundcovers, was developed by scanning hand drawn images and then importing them into MacPain. These bit-mapped images could then be duplicated as often as necessary and placed in appropriate locations on the campus map in MacDraw II. In this way, students are exposed not only to landscape plant materials but also to database managers and computer graphics capabilities. This approach also has the advantage that database information can be easily coordinated with physical location. plant materials can be sorted based on their characteristics, and information can be routinely and easily revised and updated.

The Bio-efficacy of eleven plant extracts namely viz.Neem Kernel; Rhizome of Ginger; Leaves of Datura, Gajarghas, Harsingar, Oak and Latjeera; Bulb of Garlic and Onion; Flowers of Chrysenthemum and Fruits of Chilli in the concentration of 5 percent and imidacloprid @ 40 g ai/ha was tested against mustard aphid, Lipaphiserysimi and their effect on D. rapae and Coccinellid beetle were tested in the Department of Entomology, College of Agriculture, Gwalior (M.P.). All the tested plant materials and imidacloprid @ 40 g ai/ha were effective significanty in reducing the aphid population over control.The aphid population in treated plots ranged from 7.2 to 40.0 as against 85.4 aphid/twig in untreated control. Among the plant material, three sprays of Neem Kernel were found most effective followed by three sprays of chilli fruits.All the plant extracts were found significantly safer to D. rapae and coccinellid bettle in comparision to insecticide (imidacloprid).

Recently, dye-sensitized solar cells (DSSC) have concerned significant attention attributable to their material preparation process, architectural and environmental compatibility, also low cost and effective photoelectric conversion efficiency. Therefore, this study aimed to use potential plant materials for DSSC. This research presents the extraction of natural pigments from yellow cotton flowers (Cochlospermum regium). In addition, the natural pigments were revealed that outstanding advantages, including a wide absorption range (visible light), easy extraction method, safe, innocuous pigments, inexpensive, complete biodegradation and ecofriendly. Methanol was used as a solvent extraction for the yellow cotton flower. The chlorophylls and carotenoid pigments extractions were estimated by a UV-visible spectrometer. The chlorophyll-a, chlorophyll-b, and carotenoid yield were 0.719±0.061 µg/ml, 1.484±0.107 µg/ml and 7.743±0.141 µg/ml, respectively. Thus, this study results suggested that yellow cotton flowers containing reasonable amounts appealable in the DSSC production.

The division of an estuary into homogeneous areas from both hydrodynamic and ecological standpoints is essential to any estuarine basin management model. This paper presents an approach based on a heuristic algorithm to achieve such a division. The methodology implemented through an interactive computer program named Tejo 1 applies morphological, water quality and management criteria in order to achieve the disaggregation. The approach is equally applicable to river or lake basins, with only minor adaptations. An application of Tejo 1 to the Tejo estuary is included for illustrative purposes, which resulted in the final division of the estuary into 11 homogeneous areas.
