Variations in flowering time and plant architecture have a crucial impact on crop biomass and yield, as well as the aesthetic value of ornamental plants. Aechmea fasciata, a member of the Bromeliaceae family, is a bromeliad variety that is commonly cultivated worldwide. Here, we report the characterization of AfSPL14, a squamosa promoter binding protein-like gene in A. fasciata. AfSPL14 was predominantly expressed in the young vegetative organs of adult plants. The expression of AfSPL14 could be upregulated within 1 h by exogenous ethephon treatment. The constitutive expression of AfSPL14 in Arabidopsis thaliana caused early flowering and variations in plant architecture, including smaller rosette leaves and thicker and increased numbers of main inflorescences. Our findings suggest that AfSPL14 may help facilitate the molecular breeding of A. fasciata, other ornamental and edible bromeliads (e.g., pineapple), and even cereal crops.

Abstract Manipulation of plant growth via pruning and training methods has been carried out for as long as crops have been cultivated by man. These methods serve to not only improve the aesthetic value of ornamental plants, but also to increase yields, optimise fruit quality and prolong the productive life of horticultural crops. Pruning involves the selective removal of a diverse range of plant tissue. Branches, stems, roots, buds, flowers, leaves and young fruitlets may all be pruned depending on the purpose, species and growth form of the crop this is applied to. Training methods for horticultural applications are primarily used to support the plant and the weight of produce as it develops. Training structurally alters plant form, to alter the shape, size and direction of plant growth, it also allows optimal light interception and air flow and for ease of access for harvesting and other operations.

Wood finishes are used extensively to improve the aesthetic value and protect wood products from moisture. These organic coatings generally contain volatile organic compounds (VOC) as solvents that evaporate when the coatings cure over the surface. Due to strict legislations against these hazardous VOCs, the buyers across the globe are shifting towards products finished with water borne coats. Two of the most commonly used wood coatings in India are polyurethane and nitrocellulose (NC) lacquer. This paper aims at comparing these two wood coatings with their water borne counterparts. The study was conducted on the wood substrate of Melia dubia. Chemical characterization of the cured coats was attempted through FTIR spectroscopy. Physical appearances in terms of gloss and film thickness were also studied. Bands of urethane, urea and nitric groups were identified, which helped in understanding the changes in chemical structure of the finishes after curing. The thickness of the organic coatings was significantly higher than that of their water-borne counterparts. Gloss of water based coatings was observed to be lesser than that of their organic solvent based counterparts in either coating material. In case of lacquer, the reduction was up-to 33 %. whereas in case of PU, gloss dropped down by about 54 %.

Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.

This paper considers the fundamental problem of artificial lighting in various types and scales of industrial facilities, focusing on exterior lighting design solutions. There is a lack of interest from investors, customers and society in high­quality lighting design for industrial facilities in Russia, which in many cities are very imaginative structures, practically unused in the evening. Architectural lighting of various types of installations is illustrated with photographs. The purpose of the article is to draw attention to the aesthetic value of industrial structures, provided not only by the architectural, but also by a welldesigned lighting solution.

Considers the aspects of architecture as a language able to express the current state and to prophetically indicate the upcoming changes. The aesthetic value of a construction cannot be perceived just as a separate entity, but it can be cognized in the context and not only a visual one, in space. It is necessary to see the entire complex of the accompanying phenomena, all the flow of the unfolding metaphors and values. In the model in view the figure of the author-creator must be reconsidered as no longer conforming to today's reality. The development of the Stalinist Empire style, as well as its transformations, is considered as one of the specific phenomena in the history of well-known constructions

<em>The process of folding clothes is one of the activities carried out in the laundry business or household. The activity is fairly easy but many people are still lazy to do it. As a result, clothes that have been washed will fall apart in certain rooms, thereby reducing the aesthetic value of a home. Semi Automatic T-Shirt Folding Machine is the right solution to make folding clothes easier and more time efficient. This tool is equipped with a servo motor that moves the folding board that has been designed in such a way that the user only needs to manghandle the shirt just once and simply push one button then the shirt will fold itself and will be neatly arranged through the clothes stacker board. The PID method is applied to DC motors that move under the clothes folder so that the buildup of clothes underneath will not be pressured upward when the clothes are piled up when they are folded. Ultrasonic sensor will measure the right height between the clothes with the door opening the stacking clothes with kp = 1, ki = 0.1, kd = 0.5 for thin clothes and kp = 5, ki = 1, kd = 2.5 for thick clothes so that the movement of the motor can adjust its speed . This tool can fold one shirt in 16.83 seconds 11 seconds faster than folding clothes manually</em>

This study aims to examine the decorative types of Gorontalo karawo fabrics in aesthetic and symbolic elements. Researchers want to know as made in the research design, aspects that are present in the decoration of fabrics in aesthetic and symbolic elements. This study uses a number of related theories to get results, and as a determinant, the authors use aesthetic theory, as well as historical approaches. With this theoretical basis, the author seeks to describe the aesthetic aspects and symbolic meanings that exist in Gorontalo karawo fabric. Through the data collection of the chosen motif and provide a classification of motives, the part is used as a reference for research material. The results showed that Gorontalo filigree had an aesthetic value consisting of unity formed from the overall decorative motifs displayed, complexity formed by complexity in the manufacturing process, and intensity of seriousness in the manufacturing process or the impression displayed on the filigree motif. The aesthetic form also reflects the diversity of meanings for communication, such as the symbol of a leader with his noble instincts, a symbol of cultural cooperation, which is worth maintaining, and ideas about nature conservation. This research proves that the decoration in Gorontalo filigree cloth (karawo) does not only act as a visual value, but also as a communication of cultural meanings and social status. Of all these distinctive motifs show a relationship between humans and humans and humans with nature. The influence of culture from the Philippines is also known to have a strong influence on the emergence of the Gorontalo filigree namely manila filigree.

A theory of aesthetic value should help us to make sense of how our aesthetic commitments matter to us as members of collectives. Aesthetic policies endogenous to aesthetic practices are directly justified by the network theory. The chapter looks at what aesthetic reasons we have to adopt exogenous aesthetic policies. Many argue that aesthetic practices deserve public support because aesthetic goods are public goods. A case is made for an aesthetic opportunity principle: larger social groups have reason to foster the aesthetic opportunities available to their members. The principle is applied to arts education and to communication technologies subserving aesthetic exchanges. The chapter ends with a discussion of how aesthetic opportunity interacts with—and can potentially counteract—oppressive social structures.
