The pentatomid bug Bagrada hilaris is a key pest of brassicaceous crops in several areas of the world. Previous studies suggest that mate location of this species is mediated by volatile chemicals produced by males, among which the main compound is (E)-2-octenyl acetate. However, the possible attraction of males, females, and nymphs to this compound has not yet been specifically tested. In this study, we tested the response of B. hilaris females, males, and nymphs to (E)-2-octenyl acetate using an electroantennogram (EAG) and olfactometer in the presence or absence of a host plant. Moreover, (E)-2-octenyl acetate as an attractant lure in field trap bioassays was evaluated. EAG recordings showed that this compound evokes antennal responses in B. hilaris females. Olfactometer behavioral responses showed that females and nymphs were attracted to (E)-2-octenyl acetate, while males showed no attraction. In the field trap bioassays, captures were obtained in traps baited with 5 and 10 mg of (E)-2-octenyl acetate, while in traps loaded with 2 mg and control traps, there were no recorded catches. These results suggest the involvement of (E)-2-octenyl acetate in intraspecific interactions of this species.

The outbreak of Covid-19 disease since late 2019 has led to fundamental changes in the process of globalization and liberalization of the world economy. In order to prevent the spread of this disease and control its negative consequences, many countries have implemented policies such as urban quarantine, cutting off passenger communication with neighboring countries and the world, closing tourist and tourist places, and implementing policies to protect domestic industries. In general, it led to the phenomenon of reverse globalization. According to the development of new economic convergence, which is based on the role of the market in economic relations between countries can play an important role in improving the productive capacity of countries in a region and create economic integration in different parts of the world. Such a state of integration in different parts of the world could be the solution to the process of globalization and in the post-Corona era, the concept of “one for all, all for one” was created at the regional and global level. As policy implications, the paper recommended some points to make a greater integration between Iran and Russia in the region

Abstract Tilletia controversa Kühn (TCK) is the causal agent of dwarf bunt of wheat, a destructive disease in wheat-growing regions of the world. The role of Meja, SA and Meja + SA were characterized for their control of TCK into roots, coleoptiles and anthers. The response of the defence genes PR-10a, Catalase, COI1-1, COII-2 and HRin1 was upregulated by Meja, SA and Meja + SA treatments, but Meja induced high level of expression compared to SA and Meja + SA at 1, 2, and 3 weeks in roots and coleoptiles, respectively. The severity of TCK effects in roots was greater at 1 week, but it decreased at 2 weeks in all treatments. We also investigated TCK hyphae proliferation into coleoptiles at 3 weeks and into anthers to determine whether hyphae move from the roots to the upper parts of the plants. The results showed that no hyphae were present in the coleoptiles and anthers of Meja-, SA- and Meja + SA-treated plants, while the hyphae were located on epidermal and sub-epidermal cells of anthers. In addition, the severity of hyphae increased with the passage of time as anthers matured. Bunted seeds were observed in the non-treated inoculated plants, while no disease symptoms were observed in the resistance of inducer treatments and control plants. Plant height was reduced after TCK infection compared to that of the treated inoculated and non-inoculated treatments. Together, these results suggested that Meja and SA display a distinct role in activation of defence genes in the roots and coleoptiles and that they eliminate the fungal pathogen movement to upper parts of the plants with the passage of time as the anthers mature.

Resumo A Geografia Humana, que só recentemente desenvolveu maior interesse pelo território, associa-o, conforme as circunstâncias, às idéias de poder e controle, à natureza do laço social ou ao papel das representações simbólicas. O interesse das ciências sociais pelos problemas de identidade cresceu paralelamente ao interesse dos geógrafos pelo território: a identidade está vinculada à cons-trução do “self” ou às relações com o outro, e permanece como uma noção elusiva. O território serve como uma base para sentimentos de identidade de diversos modos. A transição para a pós-mo-dernidade desafia as forças por trás de identidades tradicionais, que induzem a uma busca de identifi-cação para objetos ou paisagens. Isso provoca o fim das filosofias da História sobre as quais foram construídas as identidades e os territórios de outrora.

Abstract Human geography, which developed only recently an interest for territory, links it, according to the circunstances, to the idea of power and control, the nature of social link, or the role of symbolic representations. The interest of social sciences for the problems of identity grew at the same time than that of geographers for territory: identity is linked to the construction of self or the relations with others, and remains an elusive notion. Territory serves as a basis for identity feelings according to variable modes. The transition to postmodernity challenges the forces behind traditional identities, which induces a frienzed quest of identification to things or landscapes. It provokes the end of the philosophies of history, upon which were built the identities and territories of yesterday. The ensuing proliferation of identitary discourses expresses the deficit of sense of the world of to-day, and may be dangerous through its political consequences.

Democratic policing is now a widely and more increasingly used approach to policing around the world. New challenges produced both by the media and the law as well as the internal command and control issues call for the basic reformulation of the foundations of democratic policing. An establishment of oversight institutions over police actions is one of the items of democratic policing undoubtedly. The important opportunities to promote the oversight may emerge from the broader political changes or reforms such as the election of new political leaders, transitions to democracy, or through implementing system of human rights protection.

The largest companies that are part of the energy sector are defined by Forbes as those associated with the production of energy from nonrenewable sources and they play a very significant role in the world economy and in the generation of the command and control (C & C) function of cities. No comprehensive studies are available at the present time illustrating changes in financial performance in relation to the share of the largest firms in the energy sector in terms of their role in the generation of the C & C function. Thus, the aim of the paper is to show changes in financial performance and the impacts of energy sector companies on the C & C function of cities as well as to show spatial variances in the sector’s geography. The energy sector is developing most rapidly in Chinese cities, although it does not play a major role in the most important cities in the world via its impact on the C & C function—this may be due to rapid growth in other sectors of the economy. It is, however, very important in smaller cities. On the other hand, a large share of the energy sector involved in the development of renewable sources of energy may disturb the position of cities whose C & C function relies on energy sector companies. Thus, forecasts are needed for the sector and its impact on the command and control function of cities for the period of transition from nonrenewable sources to renewable ones. One new area of research is the formulation of methods that would allow the determination of the effects of economic recessions in the future on the financial health and C & C function impacts of the energy sector.

As late as the 1970s, conventional wisdom in epidemiology held that communicable diseases were on their way out as the predominant contributor to the world's morbidity profile, and were being replaced by noncommunicable diseases (NCDs) comprising degenerative diseases such as diabetes, circulatory disorders and cancers, and by accidents. Except for the developing countries, most of the rest of the world was already experiencing this so-called “epidemiological transition” from the terrible epoch of famines and pestilence that lasted from the dawn of mankind to the middle of this millenium, followed by the age of epidemics that culminated with the influenza pandemics of the earlier part of this century, to the prevailing situation since the 70s where diseases largely due to changed lifestyles — lack of exercise, high-fat diet, smoking and other substance abuses — predominate.

(an excerpt from the upcoming book Postdigital Arcadia) Selfie photography serves not only a traditional role of photographic (self)recording, but also for manoeuvring the space behind one’s own back. Unfortunately, as two realities, the unmediated and mediated, human and machine vision, are not matching, there are many accidents of selfie-makers due to the crabwalk. By this, the photographic technology based on the rear-view mirror – in which objects (may) appear closer than they are – finally resolves one of the largest tragedies of human self-perception; the inability to see and control the world behind one’s back. Keywords: background, mobile photography, optical devices, photography, selfie

Numerous scientific studies have been carried out on the predisposition of the Pro47Ser polymorphism of the TR53 gene to breast cancer in women living in most countries of the world. However, no studies have been conducted on the susceptibility of this Pro47Ser gene polymorphism to breast cancer in Uzbek women. In this article, genotyping of the Pro47Ser polymorphism of the TR53 gene was performed for the first time in 207 Uzbek women. According to the results of our study, the functionally dangerous T allele of the Pro47Ser polymorphism of the TR53 gene was statistically significantly higher than that in healthy donors in patients with breast cancer; (ch2 = 8.2; p = 0.004; OR = 11.2; 95% CI: 1.422-88.38; RR = 10.7; 95% CI: 1.382-82.82). The safe C allele, on the other hand, was more common in the control group than in the main group. The natural S / C genotype was found in the control group with a higher frequency than in the control group. However, the limit of the statistical difference reached a significant level: (ch2 = 8.4; p = 0.004; OR = 0.08; 95% CI: 0.01066-0.676; ch2 = 8.2; p = 0.004; RR = 0.1 ; 95% CI: 0.8489- 0.9723). The S / T genotype of this polymorphism significantly differs in the frequency of occurrence in the main and control groups. Relative risk according to statistical analysis: RR = 10.7; (95% CI: 1.395–82.07) and odds ratio: OR = 11.8; (95% CI: 1.479-93.77). It is known that the minor T allele and the S / T genotype of this polymorphism increase the risk of developing breast cancer by 10.7 times. It should be noted that the unique homozygous genotype of Pro47Ser polymorphism was not identified in patients and control groups studied by T / T. Thus, the T allele and the C / T genotype of the Pro47Ser polymorphism of the TR53 gene are important factors that increase the risk of breast cancer (r <0.05). The C allele and S / S genotype of this polymorphism are reliable protective markers against the development of this pathology. Therefore, we believe that the Pro47Ser polymorphism of the TR53 gene can be used as important genetic markers in determining the likelihood of developing breast cancer.
