    Abstract Microbes are ubiquitous in nature, and plant-microbe interactions are a key strategy for colonizing diverse habitats. The plant microbiome (epiphytic, endophytic and rhizospheric) plays an important role in plant growth and development and soil health. Further, rhizospheric soil is a valuable natural resource, hosting hotspots of microbes, and is vital in the maintenance of global nutrient balance and ecosystem function. The term endophytic microbes refers to those microorganisms that colonize the interior the plants. The phyllosphere is a common niche for synergism between microbes and plants and includes the leaf surface. The diverse group of microbes are key components of soil-plant systems, and where they are engaged in an extensive network of interactions in the rhizosphere/endophytic/phyllospheric they have emerged as an important and promising tool for sustainable agriculture. Plant microbiomes help to directly or indirectly promote plant growth using plant growth promoting attributes, and could potentially be used as biofertilizers/bioinoculants in place of chemical fertilizers. This book allows readers to gain an understanding of microbial diversity associated with plant systems and their role in plant growth, and soil health. Offering an overview of the state of the art in plant microbiomes and their potential biotechnological applications in agriculture and allied sectors, it is a valuable resource for scientists, researchers and students in the field of microbiology, biotechnology, agriculture, molecular biology, environmental biology and related subjects.

    Abstract Our country’s cultural legacy is one of the world’s most diverse, drawing millions of visitors every year to our convents and monuments, and to our museums, libraries, concert halls and festivals. In addition, it is a dynamic trigger of economic activity and jobs. Among the various scientific branches, microbial biotechnology offers an innovative and precise approach to the complexity of problems that restorers face in their daily work. This book discusses a range of topics, including the biodiversity of microbial communities from various cultural heritage monuments, microbial biotechnological cleaning techniques, the role of bacterial fungal communities for the conservation of cultural heritage, and microbial enzymes and their potential applications as biorestoration agents. Written by internationally recognized experts, and providing up-to-date and detailed insights into microbial biotechnology approaches to cultural heritage monuments, the book is a valuable resource for biological scientists, especially microbiologists, microbial biotechnologists, biochemists and microbial biotechnologists.

    Abstract Abstract When analyzing the data sampled at discrete times, one encounters successive discontinuities in the trajectory of the sampled time series, even if the underlying path is continuous. On the other hand, the distinction between discontinuities caused by finite sampling of continuous stochastic process and real discontinuities in the sample path is one of the main problems. Clues like these led us to the question: Is it possible to provide a model that treats any random variation in the data set as a jump event, regardless of whether the given time series is classified as diffusion or jump-diffusion processes? To address this question, we wrote a new stochastic dynamical equation, which includes a drift term and a combination of Poisson jump processes with different distributed sizes. In this article, we first introduce this equation in its simplest form including a drift term and a jump process, and show that such a jump-drift equation is able to describe the discrete time evolution of a diffusion process. Afterwards, we extend the modeling by considering more jump processes in the equation, which can be used to model complex systems with various distributed amplitudes. At each step, we also show that all the unknown functions and parameters required for modeling can be obtained non-parametrically from the measured time series.

    Abstract Background: This study aimed to evaluate the fear of falling, quality of life, and daily functional activity of older women aged 60 years or older with or without a history of falling.
    Materials and methods: Two hundred older adult women were recruited for the cross-sectional study in Iran. This cross-sectional study collected data from July to August 2023 through convenience sampling. The researchers collected data using a five-part questionnaire, that collected information that included demographic characteristics, the Fall Efficacy Scale in the Elderly-International Version (FES-I), 12-item Quality of Life assessment (SF-12), Instrumental Activities of Daily Living (IADL) and Activities of Daily Living (ADL).
    Results: FES-I score in older women with a history of falls was significantly higher than those without a history of falls [median: 38.0, interquartile range (IQR): 31.5-44.0 versus median: 22.0, IQR: 20.0-30.0;
    Conclusion: Overall, this study's findings highlight the adverse impact of a history of falls on three key factors: fear of falling, quality of life, and daily functional activity (including both basic and instrumental activities). The findings delineate that, ultimately, the history of falls can serve as a valuable indicator for better understanding trends in elderly care and addressing the associated challenges.

    Abstract Diversification of cultivation systems plays a critical role in ecosystem functions such as pest control, diversity of beneficial arthropods, and soil fertility. Repellent plants (releasing volatile organic compounds as arthropod repellents and providing alternative prey for natural enemies) may be used in an intercropping system for pest control; however, little is known concerning their relative priority. In this study, the impact of intercropping eggplant (E) (Solanum melongena L.) and garlic (G) (Allium sativum L.) in three designs - with row ratios of 4E:4G, 4E:8G, or 4E:12G - was assessed on the density of the two-spotted spider mite (TSSM) (Tetranychus urticae Koch), the abundance and diversity of predators, and crop yields, compared with the sole crops over two growing seasons of 2019 and 2020. In three intercrops, a significant decrease in the density of TSSM egg and mobile stages was observed compared with the sole eggplant at each growth stage of eggplant. The damage index by TSSM on eggplants was lower in intercrops (8.1-11.5%) compared with sole crop (37.0-40.3%) in the two seasons. The abundance of Stethorus gilvifrons was lower in the three intercrops than in the sole crop on the blooming-initial fruit set and the fruit development stages of eggplant. The density of Orius niger was higher in the three intercrops compared with the sole crop on vegetative growth and flowering to initial fruit set stages of eggplants. The abundance of Chrysoperla carnea was not significant among treatments. Greater values of the Shannon diversity index and the Pielou's evenness index for the construction of TSSM predators were recorded in the three intercrops compared with the sole eggplant over both growing seasons. In addition, a significant improvement in the yield per unit area of eggplant and garlic was obtained in intercrops compared with sole crops. These results indicate intercropping eggplant and garlic was a practical solution for reducing TSSM on eggplant, promoting the abundance of predators, and improving the crop yields of eggplant and garlic compared with the sole crops.

    Abstract This study aimed to determine and prioritize the selection criteria of cloud infrastructure required by AJA electronic ports. In the first step, by systematically reviewing the literature in this field and also comparatively reviewing the two industrial standards of cloud service level agreements, 24 cloud infrastructure selection indicators were identified. In the second step, by conducting a fuzzy Delphi study and utilizing the experiences of experts in this field, the identified indicators were validated, validated and refined, and then based on the consensus of experts, 21 indicators of cloud infrastructure were classified into four categories and finalized. In the third step, the indicators confirmed from the previous step were prioritized by the best-worst method. The results showed that in the selection of cloud infrastructure for AJA electronic ports, security components are effective 38.1%, functional 32%, personal data protection 19.2% and environmental and organizational 10.7%, respectively.
