In this paper, we are interested in collective behaviors of many interacting Lorenz strange attractors. With an intermediate chion coupling between the attractors,a new remarkable synchronization of well orgtried structuxes merges as a result of two competing mechanisms: temporal chaos and spatial chsive stabilization. A window of the coupling parazneter for coherent structures is found numerically. Different from all exist ing scenarios of routes to chaos (period doubling, intermittency and strange attractors), an algorithmetic increase of wavenumbers before an abrupt change to chaos (compared to the periodic doubling geometrical) is unexpectedly discovered. Metastable states are also ob served in simulations.

Objectives: Diabetes is one of the most life-threatening chronic metabolic disorders and is considered a global health problem due to its prevalence and incidence. In Morocco, several herbal preparations are utilized to treat this disease. For this reason, the current study aimed to identify and to collect data about the medicinal plants utilized in folk medicine for the treatment of diabetes in the Beni Mellal region of ***: An ethnobotanical survey was carried out among 400 herbalists, competent villagers and traditional healers from the Beni Mellal region through direct interviews using a semistructured ***: Forty-five medicinal plants belonging to 25 families were identified for their use in diabetes treatment. Interview results showed that the most frequently used plants were Olea europaea, Salvia officinalis, Allium sativum and Trigonella foenum-graecum, with a relative frequency of citation values of24.3%, 23.0%, 22.5% and 20.5%, respectively. Moreover, in this study, the Fabaceae family was the most commonly reported plant family, and the leaves and roots were the most commonly used parts, for the treatment of ***: The Beni Mellal region of Morocco has an important floristic biodiversity of plants used to treat diabetes in traditional medicinal practice. This result provides a good database for pharmacological screenings in the search for plant-based antidiabetic medications.

For the past ten years there has been much progress in computational fluid dy- namics (CFD), among which the formation and development of the lattice Boltz- mann method (LBM) are an important new direction. We give a review on the main aspect and the latest development of this method in this article, and at the same time we also discuss the related development of scientific software and its impact on the real-world applications in industry.
