Chemical pesticides increasing use caused increased resistance in insects and increases the residue of pesticides in agricultural products and the environment.

The aims of this study was to achieve a safe method and using natural essential oils of Cupressus against adult insects of the wheat flour (Tribolium castaneum Herbst).

A factorial experiment was conducted in a completely randomized design in four replications in 2018. The Cupressus essential oils (EO) Clevenger by water distillation method and measured by GC-MS. Relative growth rate (RGR), repellency and nutritional indicators, and fumigant toxicity of EO on mature Tribolium castaneum Herbst were investigated in 27 ± 1 °C and 65 ± 5 % relative humidity.

Alpha-pinene was the major component of the EO in the studied species. The results of the fumigant toxicity test of essential oils showed that increasing concentration and duration of exposure to essential oil caused an increase in the mortality of T. castaneum. Among the studied species, C. sempervirens (France) with LC50 = 256.93 µL / L air had the highest fumigant toxicity (87.5%) on T. castaneum.

Based on the insecticides, repellents and nutritional indices effect of Cupressus essential oils on T. castaneum they can be used as a biological management method for controlling storeroom pests.

Metaverse can be defined as a shared virtual space resulting from the combination of physical reality, online games, augmented reality, virtual reality and digital currencies, which enables users to interact with each other virtually. According to Asr Iran, smartphone, cloud computing, artificial intelligence, machine learning and blockchain are some of the revolutionary examples that have attracted the attention of the technology world in the past. "Met averse" is one of the newest keywords in the world of technology and has attracted so much attention that it has become a major target for many of the world's technology giants. The newest concept that has become very popular among people today is Met averse. Currently, if we want to access the virtual world using the Internet, we are limited to the screen of a mobile phone or a computer or laptop screen, but Metaverse has removed these limitations and will introduce you to a world beyond space. Ever since Facebook rebranded its company as Meta, discussions and debates have been going on about what the Metaverse is. The concept has been around for nearly three decades, but today the Met averse has suddenly become a hot topic.

The vast divine mercy is always flowing from the essence of God Almighty to the creatures. Due to the incompatibility of creatures with the essence of God, there is a need for a mediator to receive His mercy and deliver it to the creatures. This mediator in the present age is the Master of the Age (A.T.F.S). Although we are deprived of the blessings of his legislative guardianship during his absence, the study of his worldly position as a mediator of divine grace is a subject that we have addressed using a descriptive-analytical method and by examining three attributes of his. The most important achievements of this article are as follows: The full manifestation of the master of the age for all divine names and also the proportion to all worlds of existence by appearing in all names as the manifestation of the comprehensive name "Allah" has determined the status of divine caliphate for him. Through the treasuries of the divine names, which are as his powers, the Imam manages the affairs of the universe and bestows the grace on all creatures. He is in every moment and instant with a manifestation of the divine manifestations and devises a world of the worlds of existence; and this association with manifestations at all times is based on his divine name "Al-Adl".

A significant amount of crop production is destroyed annually by pests in the storage and significant damage is caused to crops. Recently, the use of essential oils as an alternative to pesticides in pest control has been considered. Due to the presence of α-pinene, Cupressus genus is a significant source of plant insecticides that can act as fumigant, repellency and inhibitory insecticides.

The aim of this study was to investigate the insecticidal properties, repellency and nutritional parameters of essential oils of Cupressus species on Sitophilus oryzae in 2018.

The experiment was conducted in a factorial arrangement based on completely randomized design with 4 replications. The essential oils of the different species and populations of Cupressus were prepared by the Clevenger apparatus using a water distillation method. The major constituents in the essential oils were analyzed by GC-MS and the biological effects of the essential oils against adult S. oryzae were investigated.

In the analysis of chemical compounds, α-pinene was identified as the main essential oils of the above species. The result showed that among the species, C. arizonica showed the highest Fumigant toxicity to S. oryzae with LC50 = 172.30 μl/L air. In investigating the effect of repellency on S. oryzae, essential oils of C. sempervirens L. var. horizontalis (France) with 80.61 % showed the highest distance.

Due to the toxicity and high repellency effect of Cupressus essential oils on S. oryzae, this genus has high potential for use in storage pest control.

Despite the growing role of celebrities in shaping tourists' favorable reactions to destination brands, there is little information about the structure or function of the structure in destination settings or arched tourism areas. In response, this study hypothesizes four elements for influencing celebrities and examines how they affect the relationship between self-branding and brand partnerships, which precede brand interaction and loyalty to the destination. The subjects of this study were potential tourists who were familiar with Chinese literary figures (Jin Yong) and related destinations (Shaolin Temple). SPSS 25 and AMOS 22 software were used to analyze 405 valid data obtained through an online survey from October 7 to 21, 2020. The results of structural equation model analysis showed that all measurement scales are valid and reliable. In addition, all four elements of celebrity influences (ie trust, expertise, brand consistency, and familiarity) predicted the success of the brand relationship itself and brand engagement. Also, the self-branding relationship and brand participation significantly contributed to brand interaction and explained the significant variance in destination loyalty. The findings show the background nature of the effects of celebrities and how tourists react to destination brands.

Pimpinella anisum L. belongs to Apiaceae family. The samples of vegetative and reproductive organs at different stages of development were gathered and investigated by cell-histology methods. The investigation of the anatomical structure of vegetative organs showed that the secretory ducts are arranged between the parenchymal tissues of the leaf. Section of flower buds revealed that anthers had 4 pollen sacs, the division of pollen mother cell was of the simultaneous type, microspore tetrads were of tetragonal type and the tapetum layer was secretory. The study of the ultrastructure of pollen grains with SEM showed that they had 3 pores. The ovary was found to be two-chambered and two-carpeled the ovule to be anatropous and to have one membrane. In embryogenic investigation it was found that the embryos were globular, cotyledonary and torpedo-shaped and the transition between globular embryos to cordate embryos was found. The vegetative organs were observed to have the general structure of dicotyledons. The development patterns of ovule and embryo sac follow the Polygonum type. Tetrahedral microspore tetrads were observed. The ultrastructure of pollens was found to be similar to those of Smyrnium, a genus of Apiaceae family. All stages of embryogenesis were covered in this study.

The red flour beetles Tribolium castaneum is one of the most important pests of stored products, to control this pests plant extracts are suitable components as alternate for chemical pesticides. On the other hand herbs as natural resources that are antioxidant properties, The attention of researchers for use in the food and biological systems are located. In this research theefficiency of Pimpinella anisum extract on biological activity of anise Tribolium castaneum and its antioxidant functional is evaluated. In this study, the effect of seed extract of anisum on nutritional indices of adults T.castaneum, in 3 concentrations 50, 75 and 100 µl and respiratory toxicity effects of extracts ( 50, 89, 158, 281, 500 µl of extract per liter of air) was in vitro (29 ± 1°C and 65 ± 5% R.H.). Also the antioxidant effects of P.anisum was investigated by two methods, radical scavenging, DPPH (2, 2-diphenyl-1-picrylhydrazyl) method and reducing power of iron method. Nutrition a lindices showed that the highest and lowest concentration, respectively, has 86/94% and 68/82% inhibition of feeding. The highest mortality concentration was 500 µl/L of air at 24 hours. The required concentration to 50% mortality of population (LC50) at 24 hours after treatment was 215/19 µl/L of air. In DPPH test, the 50% inhibitory concentration of leaf extract was higher than seed extract, the same result was obtained from the power reducing of iron test.

Collective identity is a joint way of thinking, feelings and sentiment of a group. From the modernity viewpoint, on the base of symbolic interactionism, it excites a strange sense of attachment, affinity, and obligation among the group members, and facilitates the process of self exploration of the social actors and reflection of people’s attitude towards them. Iranian identity is a collective identity that has a macro level than the other micro-identities that live in Iran, and enjoys a special greatness and dignity and its elements have formed during a long period of history.This article has considered Iranian identity in Kurdish poetry using documentary method and content analysis, and on the base of historical backgrounds, has considered several dimensions of Iranian Identity, such as “Persian Language, socio- cultural structure, territory, political and religion, and it has designed analysis units for each category.
