The emergence of many problems in the global supply chain has accelerated the digital transformation in the food industry, but studies show that the rate of innovation and the use of new technologies in Iran's food and beverage industry is slow, and few studies have been conducted. The current research was conducted with the aim of reducing the gap between studies. For this purpose, the conceptual model of Herandi et al. (2022) was chosen as the basic model to identify and prioritize the maturity criteria of digital transformation capability. Also, for the first time, the fuzzy DANP technique was used to extract, determine the weights, and prioritize the criteria and sub-criteria of digital transformation maturity in this industry. The results showed that among the selected industries in Tehran province, infrastructure criteria, digital senior management criteria, and digital delivery leadership criteria were ranked first to third, respectively. Also, the criteria of digital leadership and senior management are effective criteria for infrastructure, especially digital culture. Sub-criteria of human, managerial, and technical infrastructures are also among the sub-criteria of influence and cause. Also, among the criteria of digital senior management, the sub-criteria of digital planning and guidance, environmental monitoring, and digital networking have the effect aspect, and digital coordination and actions have the cause aspect. Among the digital transformation leadership criteria, only the sub-criteria of digital resources are of the effect type, and the rest of the sub-criteria are of the cause type.

Throughout its history, modern Iranian art saw the rise of several movements that, influenced as much by modernist ideas as values of the past, aspired to develop a “national art.” At the core of these movements was a neo-traditionalist approach that presented a contemporary take on the hallmarks of Iranian traditional arts while emphasising a native character, an approach that paved the way for the Saqqakhaneh movement of the 1960s.Aiming to understand Saqqakhaneh artworks better, this paper explores what neo-traditionalism meant in that movement. The article’s main question is: “What visual elements connect Saqqakhaneh paintings to neo-traditionalism and how?” Conducted as qualitative and descriptive-analytical research, the study looked at paintings by Sadegh Tabrizi, Hossein Zenderoudi, Faramarz Pilaram, Mansoor Ghandriz, Nasser Ovissi, and Massoud Arabshahi, selected through stratified random sampling.The analysis found that the artists crafted a novel artistic language upon their contemporary interpretations of traditional culture, forging a structural interaction between modern art and Iranian decorative art: Hossein Zenderoudi embodied neo-traditionalism in his works by showcasing the visual potentials of Persian calligraphy, as well as by taking familiar Saqqakhaneh motifs and arranging them regardless of their naturalistic qualities and their meanings. Similarly, neo-traditionalism manifests itself in the works of Faramarz Pilaram through the artist’s novel approach to calligraphy. Pilaram treated the Shekasteh-Nastaliq script as raw artistic material, harmonising calligraphic strokes into figurative art. Another neo-traditionalist feature of his works is the use of the colour gold, which hallmarks his style. Mansoor Ghandriz developed a style of abstract iconography that drew on folk symbolism, creating a medium for neo-traditionalism. Inspired by modernist ideas, he also experimented with an intuitive approach to art. His work reflects an effort to reconcile the aesthetics of abstract painting with Persian artistic traditions. Nasser Ovissi expressed his neo-traditionalist approach by bringing mythical symbolism and lyrical themes into a modernist setting and also by incorporating the aesthetics of different Persian miniature painting styles into a cohesive whole. Sadegh Tabrizi built his style upon a personal interpretation of the aesthetics of Persian miniature. Lastly, Massoud Arabshahi represented neo-traditionalism in a modernist form that he developed by revisiting the ancient world through Eastern eyes.Neo-traditionalism was thus realised in the art of Saqqakhaneh painters, who revealed in their unique works the visual potentials found throughout the history of Persian art. To answer the research question, which concerns how neo-traditionalism is represented in Saqqakhaneh paintings, the paper analyses twelve paintings from the movement and shows that certain elements from Iranian visual culture—including Siyah mashq (calligraphic practice sheets), imagery from Iranian folk literature, Islamic imagery, and aesthetic characteristics of Persian miniature traditions—are rendered in a modern artistic language. Relying on their distinct interpretations of cultural imagery, Saqqakhaneh artists pioneered a particular form of Iranian modernism using a traditional visual vocabulary.Conceptually overlapping with postmodernism, neo-traditionalism reveals a tendency towards postmodern art and, in general, qualifies stylistically and content-wise as a pluralist approach. On a deeper level, however, attention to a native and national identity is the defining feature of neo-traditionalism, which aims to tailor tradition to the tastes of the contemporary viewer by blending familiar traditional imagery with modern styles of representation.

Co-inoculation of plant growth promoting bacteria and biological control agents, is a strategy to improve health, yield and quality of crop production. The objective of the present study was to evaluate interactions of two bacterial strains, Bacillus amyloliquefaciens UTB96 and Azospirillum oryzae NBT506, on growth promotion of wheat and control of the causal agent of Fusarium head blight, Fusarium graminearum. The results showed that single and co-culture of these strains inhibit mycelium growth of F. graminearum by direct inhibition and volatile organic compounds. In germinator assays, different wheat growth features were increased and disease index was decreased. Results showed that co-inoculation or single application of the bacteria in the soil significantly enhanced root length (14-80%), root fresh weight (18-167%), root dry weight (4-110%,), shoot length (17-61%), shoot fresh weight (47-169%) and shoot dry weight (up to 90%). In addition, a significant decrease in disease index (62-100%) was observed in different single and co-culture treatments. In conclusion, the studied two bacterial strains showed synergistic effects on wheat growth promotion and fungal growth inhibition.

Aspergillus flavus grows on a wide range of agricultural and food products and causes contamination with aflatoxin. One of the suitable methods for controlling aflatoxin is the use of biological agents, which is possible by the application of effective bacterial antagonists. The objectives of the present study were to isolate and characterize a superior biocontrol agent against the above-mentioned fungus on pistachio, to develop an industrial culture medium and to optimize its growth conditions for enhancing maximum biomass production for Bacillus amyloliquefaciens UTB96. According to the results, this strain was capable of significant growth inhibition of A. flavus and reducing aflatoxin concentration in the pistachio up to 98.38%. Moreover, its VOCs showed growth inhibition as well. The most effective environmental factors were screened using the Bremenplacket design, in terms of their effects on the biomass production of the antagonistic bacterium and optimizing the production of bacterial biomass in culture medium designed using the screened factors. The results showed that sugarcane molasses and corn steep could be used as the industrial sources of carbon (C) and nitrogen (N) in production at 10 and 2 g/l respectively. Optimum conditions for maximum production of biomass in this culture medium included pH=7, 30°C and C/N ratio 1:23. Using the optimized culture medium and conditions in a semi-industrial method, the amount of biomass was reached up to 0.17 g/l, and the antagonistic effects increased by 8%. Bacillus species used in this work shows some similarities with B. velezensis that needs to be validated by further molecular analysis.

In order to remain dynamic and to make oneself distinguished, an artist may take different approaches; approaches which may, in turn, create new styles in art. If such an approach can be named going beyond oneself, then many artists may be nominated to have practiced it making novel styles. Going beyond oneself often follows two distinct ways: being inspired by other artists or adopting an anti-style action by the artist. Interestingly enough, it sometimes happens that certain artists, irrespective of their nationality or of their way of thinking, have become very close to each other in terms of artistic outlook and taste. Accordingly, a considerable amount of similarity can be seen among their works. Being inspired by one another has led to creation of novel artistic styles. Two of such artists are Kamalodin Behzad and David Hockney. Both went beyond themselves and beyond the common painting styles; the former by challenging his own style and the latter by being inspired by the oriental painting style. This research aimed to study certain works of Kamalodin Behzad and David Hockney comparatively in order to analyze and evaluate the similarities among their works and, hence, to examine the process of going beyond oneself by the artist. The data were mainly collected from library sources.  The result of the study indicated that in the course of going beyond oneself, the styles are incorporated. It is, in fact, the very incorporation, in terms of form and content, that gives birth to new movements in art as well as to novel artistic styles.

Finding new strains of plant probiotic bacteria is an important step in commercialization process. In this study, the biological and biochemical features of Pseudomonas fluorescens UTPF5 is evaluated as an important bacterial in Iran. This strain produces metabolite such as auxin, hydrogen cyanide, siderophore and DAPG, but not phenazin. Biofilm formation, regulator systems examined. Also inhabitation of fungi growth such Rhizoctonia solani is determined. Addition of Fe2 reduces the production of siderophore but increases hydrogen cyanide. The strain UTPF5 produces Gac/Rsm signal and increases hcnA and RsmZ expression. It produces no AHL signal. Biocontrol potential and plant growth promotion in sunflower, millet, canola and bean is described by application of the bacterium in greenhouse trials.
