Natural compounds have long been civilization’s companion, and yet they still evoke an aura of mystery that transcends their applications. This may have to do with their origins; take for instance the ever-dependable aspirin, hailing from the bark of the willow tree and steeped into a bitter brew since antiquity. Other molecules such as ascorbic acid, quinine, or penicillin have equally compell...
scheduling has become an attractive area for artificial intelligence researchers. on other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. a maintenance program may be considered as the heath care of manufacturing machines and equip...
Climate change alters the abiotic constraints faced by plants, including increasing temperature and water stress. These changes may affect flower development and production of flower rewards, thus altering plant-pollinator interactions. Here, we investigated the consequences of increased temperature and water stress on plant growth, floral biology, flower-reward production, and insect visitatio...
Action thresholds are traditionally based on the density of pests and the economic damage they cause to crops. Pest damage assessments are usually made in a "sterile" environment, devoid of extenuating factors such as predators, parasitoids, and alternative food sources. Recently, the effects of a predator or parasitoid species have been considered. However, interactions between natural enemy s...
Flower induction in apple (Malus domestica Borkh.) trees plays an important life cycle role, but young trees produce fewer and inferior quality flower buds. Therefore, shoot bending has become an important cultural practice, significantly promoting the capacity to develop more flower buds during the growing seasons. Additionally, microRNAs (miRNAs) play essential roles in plant growth, flower i...
Aims Floral traits are frequently used in traditional plant systematics because of their assumed constancy. One potential reason for the apparent constancy of flower size is that effective pollen transfer between flowers depends on the accuracy of the physical fit between the flower and pollinator. Therefore, flowers are likely to be under stronger stabilizing selection for uniform size than ve...
Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...
Flowers of Nelumbo nucifera Gaertn, Hibiscus rosa-sinensis L., Calendula officinalis L., Datura metel L., Jasminum sambac L Aiton., Mimusops elengi L., Nyctanthes arbor-tristis L., Saraca asoca (Roxb.) Wilde., Tabernaemontana divaricata (L.) R. Br. ex Roemer and Schultes., and Ixora coccinea L. are very popular for their aesthetic and spiritual appeal. Indigenous treatment systems found these f...
Flower pollination algorithm is a new nature-inspired algorithm, based on the characteristics of flowering plants. In this paper, we extend this flower algorithm to solve multi-objective optimization problems in engineering. By using the weighted sum method with random weights, we show that the proposed multi-objective flower algorithm can accurately find the Pareto fronts for a set of test fun...
