IoT is an assembly of equipment of different calibers and functionality working towards a single goal. A blockchain is a computerized record that contains the whole history of exchanges made on the system. A multi-WSN arrangement model is structured. The hubs of the IoT are isolated into base stations, group heads, and conventional hubs as per their capacities, which encourage the administration and participation of the hubs. A hybrid blockchain model is proposed. To fit the multi-WSN arrange model better, as indicated by the various capacities and energies of various hubs, neighborhood blockchain and open blockchain are sent between group head hubs and base stations individually, and a crossbreed blockchain model is framed. A shared validation plot for IoT hubs is proposed. For group head hubs, the creators utilize the worldwide blockchain for validation, and for customary hubs, they utilize the nearby blockchain for confirmation. The proposal aims in increasing reliability by 1.17% and minimizes sinkhole attack by 2.42% compared to previous contribution.

Summary Objectives: to analyze factors that might indicate familial predisposition for ovarian cancer in patients diagnosed with this disease. Methods: in a prospective single center cohort study at the Institute of Cancer of the State of São Paulo (ICESP), 51 women diagnosed with ovarian cancer were included. Familial predisposition for ovarian cancer was defined as having a higher than 10% chance of having a BRCA1/2 mutation according to the Manchester scoring system, a validated method to assess the likelihood of mutation detection. Each patient was interviewed with a standardized questionnaire on established risk factors for ovarian cancer and other factors that might influence the risk to develop ovarian cancer. Logistic regression analyses were performed to estimate the impact of the evaluated factors on the likelihood of mutation detection, by calculating odds ratios and 95% confidence intervals. Results: seventeen out of 51 patients had a family history of breast and/or ovarian cancer, four patients had a history of breast or endometrial cancer, 11 were diagnosed before the age of 50, and 12 presented a risk of familial predisposition to ovarian cancer higher than 10%. Patients with comorbidities, such as hypertension, diabetes, hormonal disorders, dyslipidemia and psychiatric conditions, presented a lower chance of having a familial predisposition for ovarian cancer (OR: 0.22; 95% CI: 0.06-0.88; p=0.03). Conclusion: in this study, having comorbidities was associated with a lower risk of having a familial predisposition for ovarian cancer. Other factors associated with the risk of ovarian cancer did not have an impact on this predisposition.

Hermann Cohen

My aim is to prove that Hermann Cohen was not only a philosopher of dialogue but has played an exceedingly important role in the history of that current of thought. His books Ethics of Pure Will (1904) and Religion of Reason out of the Sources of Judaism (1919) offer a detailed analysis of the relationships between I and Thou, I and It, I and We. In the first book these relationships are considered from the ethical-legal point of view and in the second from the viewpoint of religious anthropology. However, Cohen considers the problem of inter-personal relationships not in isolation, but as an important component of his entire philosophical system. Deduction of the concept of personality in Ethics of Pure Will is based on Cohen’s logic of the origin expounded in the first part of his system in The Logic of Pure Cognition. Cohen explains that the origin of the self-consciousness of I as a personality is not the external world, but another person, i.e. Thou. In turn, the partnership relationships between I and Thou create the community We which forms the basis of the law-governed state. The process of artistic creation in the framework of inter-personal relationship is explored in Aesthetics of Pure Feeling. Finally, Religion of Reason out of the Sources of Judaism formulates the conception of religion as the most complete realisation of inter-personal relationship. Thus, dialogism became an important dimension of Cohen’s entire philosophical system, a fact noted by Martin Buber. Franz Rosenzweig, in unfolding dialogical thinking, expressly appeals to all the elements of Cohen’s system. There are signs of his influence on Bakhtin’s doctrine. Thus, examining Cohen’s doctrine as part of the philosophy of dialogue gives insights into this entire trend as a coherent whole.

The article discusses such a new phenomenon of modernity as the rehabilitation of utopia, which has not yet become widespread, but it is a serious symptom of the crisis of civilization in Russia and in the West. It is shown that attempts to rehabilitate utopia are associated with the situation of crisis, uncertainty, unpredictability caused by the ongoing transformations of the modern epoch. Under these conditions, the utopia is not only a reflection of the existing situation but also an opportunity for the formation of new ideas and the reduction of uncertainty. Many astute researchers in both the West and Russia demonstrate a positive attitude towards utopia, as they see the opportunities offered by utopia, especially in times of crisis. It is noted that in Russia there is a gradual overcoming of the negative attitude to utopia, which was associated with the collapsed socialist system. A summary history of utopia shows that utopia is a significant factor in history that accompanies the development of mankind throughout history. Despite this, in the earlier decades of the 20th century and the beginning of 21st century the “death of utopia” was declared, it was driven by ideological and political reasons and by globalization in general. Meanwhile, at present its importance is again actualized in relation to the complex international situation. Therefore, both in the West and in Russia there is a growing demand for the ideal concepts of the future of human existence in the form of utopia.

AbstractThe 36Cl dating method is increasingly being used to determine the surface-exposure history of Quaternary landforms. Production rates for the 36Cl isotopic system, a critical component of the dating method, have now been refined using the well-constrained radiocarbon-based deglaciation history of Whidbey and Fidalgo Islands, Washington. The calculated total production rates due to calcium and potassium are 91±5 atoms 36Cl (g Ca)−1 yr−1 and are 228±18 atoms 36Cl (g K)−1 yr−1, respectively. The calculated ground-level secondary neutron production rate in air, Pf(0), inferred from thermal neutron absorption by 35Cl is 762±28 neutrons (g air)−1 yr−1 for samples with low water content (1–2 wt.%). Neutron absorption by serpentinized harzburgite samples of the same exposure age, having higher water content (8–12 wt.%), is ∼40% greater relative to that for dry samples. These data suggest that existing models do not adequately describe thermalization and capture of neutrons for hydrous rock samples. Calculated 36Cl ages of samples collected from the surfaces of a well-dated dacite flow (10,600–12,800 cal yr B.P.) and three disparate deglaciated localities are consistent with close limiting calibrated 14C ages, thereby supporting the validity of our 36Cl production rates integrated over the last ∼15,500 cal yr between latitudes of 46.5° and 51°N. Although our production rates are internally consistent and yield reasonable exposure ages for other localities, there nevertheless are significant differences between these production rates and those of other investigators.

We have followed the story of the Three Age System a very long way indeed. We saw how it emerged in Copenhagen and Lund, how it was received there, and how Worsaae fought to establish it there. We then saw how it came to Britain, and followed in Worsaae’s footsteps from London to Edinburgh to Dublin and back to London again. In each of the three capitals in which it was considered, accepted or rejected, the academic context was quite different from the others. In London the archaeologists were safe sheltering under the dominant ethnological paradigm, and for some time saw no reason to venture out from beneath it. In Edinburgh the Four Stage Theory and long links with Denmark made the Scandinavian story much easier to swallow rapidly. In Dublin the historical elite was so blinded by the glory of their ancient history that there was no place for the archaeological theory, and it had to be carried into the capital by an originally provincial archaeological movement. Back in London, the safe ethnological chronology was jolted out of alignment by the discovery of human antiquity, and alongside this—and on the back of high-quality archaeological excavation—the Three Age System finally won the day. Some aspects of the story have long been well known. The roles of C. J. Thomsen, of J. J. A. Worsaae, of Daniel Wilson, and of John Lubbock have all received much exposure in discussions of the history of archaeology. But in following this story we have also sometimes looked beneath stones that have seldom if ever previously been lifted in this connection, at least in the Anglophone literature. It has for example rarely been understood that Thomsen’s ‘idea of prehistory’ was not simply forging back into hitherto uncharted chronological territory, but was to begin with leaning on the elaborate ancient historical structure of Peter Frederik Suhm. It was only when Christian Molbech kicked away this structure in the 1830s that the Three Age System had to stand on its own. Fortunately it was rapidly supported by three other chronologies employing physical evidence, and they acted as supports in its very earliest days of independence. When Worsaae hastened ancient history into its grave in the 1840s, the Three Age System was therefore able to stand on its own four feet (archaeology, economy, ecology, and craniology).

Aromatic compounds have a long history of use as medicines in most recorded cultures. An increasing interest in these therapeutic volatile molecules in both scientific and lay communities has led to the advancement of essential oils as phytomedicines. Recent discoveries suggest essential oils augment the endocannabinoid system in a positive manner to mitigate various pathologies. However, the exact mechanisms whereby essential oils influence endocannabinoid system activity are not fully known, these studies provide a glimpse into their involvement and warrant further evaluation. Additional study of the interaction between essential oils and the endocannabinoid system may lead to promising phytomedicines for the treatment of diseases and conditions involving dysregulation or activation of the endocannabinoid system.
