    Tires are a component of two-wheeled and four-wheeled vehicles, such as cars, motorcycles, and bicycles. Tires have a role that is so that the vehicle can move. Tires can also be used to reduce vibration caused by road irregularities, protecting the wheels in a vehicle from damaged or uneven roads. Some vehicle tires can be damaged or punctured if they hit a sharp object such as a nail or thorn. In addition to being exposed to sharp objects, vehicle tires can also thin out if the tires are used for very long time, so it can no longer be used on any vehicle. Therefore, vehicle tires that are not suitable for use can be reused by recycling, one example is being used as plant pots. Therefore, vehicle tires that are not suitable for use can be reused by recycling, one example is being used as plant pots. So with that, researchers will create a software that can explain a way to recycle vehicle tires into plant pots with software, namely Augmented Reality. To design and implement a video of vehicle tire recycling using Augmented Reality with the Multimedia Development Life Cycle method. The method of the Multimedia Development Life Cycle consists of 6 stages, namely Concept, Design, Material Collection, Presentation, Experiment, and Distribution. The result of the end of this research is a video in the form of Augmented Reality to learn how to recycle vehicle tires into plant pots in the form of Augmented Realit

    Acanthamoeba keratitis is a blinding infection that is becoming increasingly important in human health. Early diagnosis is a prerequisite for successful treatment and requires identification of Acanthamoeba at the genotypic level. The genus Acanthamoeba consists of both pathogenic and non-pathogenic species and has been recently classified into 13 different genotypes, T1-T12 and T14. More importantly, 95% of Acanthamoeba isolates that produce keratitis belong to T4 genotypes. In this study, we attempted to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence. We isolated 18 Acanthamoeba isolates from environmental samples in Ankara, Turkey and determined their pathogenic potential by means osmotolerance, temperature tolerance and in vitro cytotoxicity assays using corneal epithelial cells. Ribosomal DNA sequencing revealed that 10 isolates belong to T2, 5 belong to T3, 2 belong to T4 and one belongs to T7 genotype. As expected, T3 and T4 isolates exhibited the most pathogenic traits and were osmotolerant, temperature tolerant and exhibited severe corneal epithelial cell cytotoxicity indicating their pathogenic potential. Overall these data indicate that high frequency of T4 isolates in keratitis cases may well be due to their greater virulence. This is the first report presenting environmental distribution of Acanthamoeba in Ankara, Turkey

    Equipment developed for the study of gas exchange in germfree plants is described. The equipment includes a gas exchange chamber to house the plant under study, a gas feed assembly to introduce and remove gas from the chamber, and a clinostat to rotate the apparatus. Fluorescent and incandescent lights are used to illuminate the chamber and a sealed plastic barrier is used to isolate the potting soil from the chamber atmosphere. The gas outflow from the chamber can be diverted to an infrared CO2 analyzer. The performance of the system was evaluated

    Dispersal of Calluna vulgaris(L.) Hull. seeds on a severly burnt upland moorland

    Get PDF
    From natural and manipulated experiments at 460 m a.s.l., traps were used to record the dispersal range of Calluna vulgaris seeds on an unvegetated post-wildfire site. Seeds were trapped to 50 m from source, although most (73%) were deposited within one metre of the parent plant. C. vulgaris seeds were not dispersed as far in these experiments as recorded in previous workers’ experiments on lowland grassland

    The effects of different NPK nutrient doses on red pepper's yield and vegetative parts in pots

    Red pepper (variety 'Hírős') was cultivated in plant pot, in the research garden of Kecskemét College Faculty of Horticulture. Plant pots were in semi-subsurface position full with sandy soil typical for the Danube-Tisza sand ridges. Our aim was to investigate changes in productivity, yield and NPK content of leaves in correlation with increased NPK doses on sandy soil with low humus content and average nutrient supply. We used Hydrofert NPK 15-30-15 fertilizer. The amount of nitrogen and potassium per hectare were 150 300, 450, 600 kg, and the amount of phosphorus was the double of these. Fertilizer was spread with irrigation into the soil of plant pots. Total doses were applied in three equal portions, between May and July in all treatments for better nutrient utilization. Harvest was during the biological ripeness of red pepper, between August and September Compared to the control samples, yield increased spectacularly in every treatment. At the same time, utilising the highest amount of fertilizer did not decrease the yield compared to smaller amounts. It means we can reach balanced increase of yield with high amount of NPK fertilizer on sandy soil. High salt concentration in the root zone did not hinder the development of the plants

    THE INFLUENCE OF ‘GANG BARU’ TRADITIONAL MARKET ACTIVITIES IN THE USE OF PUBLIC SPACE IN SEMARANG CHINATOWN

    Get PDF
    Chinatown is one of the commercial district in Semarang city, which continues to grow in the city center. It’s a 'generator' that drives a wide variety of economic activities, also self-actualization and disclosure of aspiration, expression of the people. One landmark Semarang's Chinatown is the traditional markets Gang Baru. Activities in Gang Baru includes selling/trading, the parking, loading and unloading on public space. The purpose of this study to analyze the traditional market activity in the public space by taking the characteristics of the cultural space. There is a relationship and influence between the market activity with the condition of public spaces in Gang Baru traditional markets and surroundings. Market activity effects change the social society condition in the field of the economic activities, using the dwelling house to shophouse, social interaction takes place between merchants and owner shophouse. The majority of Chinese societies ethnic are receiving the traditional market activity Gang Baru because it is a cultural heritage activities that has historical value, they continue the family business in this market. The trade time for the activities of buying and selling traditional market in the Gang Baru street give a strong influence on public space. Market activity give effects the disruption of the circulation, use of the road and pedestrian areas to the activities of hawkers, parking and unloading of goods

    How do parking practices structure urban territorial communities?

    Get PDF
    In this article we analyse the socio-spatial contexts and consequences of the practice of car parking in housing estates. Fredrik Barth’s idea of socially constructed boundaries and the theory of social practice form the theoretical basis of our analysis. The empirical material comes from research conducted in 2016 and 2017 in three Polish cities. We analyse the practice of parking in terms of the specific aspect of mobility that is ‘mooring’. The research shows that parking practices influence the structuring of territorial communities in housing estates on two levels: everyday activities, norms and rules, as well as social differences and boundaries in the space occupied by the housing estate

    Sand to Root Transfer of PAHs and PCBs by Carrots Grown on Sand with Pure Substances and Biosolids Amended Sand

    Get PDF
    A study on behaviour of trace organic compounds (Polycyclic Aromatic Hydrocarbons, PAH, and Polychlorinated Biphenyls, PCB) in a sand-plant system has been carried out, with the reclamation of wastewater treatment plant biosolids for agriculture in mind. Carrot plants (Daucus carota) were grown on soilless culture (sand), to provide optimal transfer conditions, in plant containers inside a temperature regulated greenhouse. There were two types of experiment. The trace organic compounds have initially been introduced as pure substances. A second experiment has been carried out under the same conditions, but using biosolids. Plant development has been unaffected by the presence of the pure substances and the biosolids. The transfer of the trace organic compounds has been followed in the peel, the core and the leaves of the carrot plants. Results obtained are expressed as fluxes of the trace organic compounds into the plant. The results clearly show that trace organic compounds accumulate in the carrot peel

    Testing and improving the effectiveness of trap crops for management of the diamondback moth Plutella xylostella (L.): a laboratory-based study

    Get PDF
    BACKGROUND: The aim of this study was to assess white mustard (Sinapis alba L.) as a trap crop for diamondback moth [Plutella xylostella (L.)] on cauliflower [Brassica oleracea (L.) var. Lateman]. Moth behaviour on these plants and the importance of plant age and size in maintaining pest preference for trap crop plants were also investigated. RESULTS: Three times as many eggs were laid on cauliflower plants that were unprotected than on plants protected by a trap crop of white mustard. Moths remained longer on the mustard plants as a result of a doubling in the mean duration of information-providing behaviours. Plant age had little effect on P. xylostella host preference. When plant age was constant, percentage oviposition on mustard was higher when these were larger (93%) than copresented cauliflower plants, compared with when they were smaller (68%). CONCLUSION: Trap cropping with white mustard may reduce the incidence of P. xylostella in cauliflower crops. The pest management benefits of trap crops may be maximised by using trap crop plants that are larger than the main crop plants, although relatively smaller trap crop plants may still be preferred as hosts for P. xylostella per se.
