Abstract Humans are exposed daily to low concentrations of many different chemical substances, natural and some man-made. Although many of these substances can be toxic at high levels, typical exposures are far below the effect levels. The responses produced by man-made aromatic hydrocarbon receptor agonists, such as dioxins, polychlorinated dibenzofurans, coplanar polychlorinated biphenyls, and polycyclic aromatic hydrocarbons, are also produced, often to greater extents [corrected], by naturally occurring constituents of fried meat, cabbage, broccoli, cauliflower, cocoa, and curry. Our society seems to be concerned about the health risks associated only with the synthetic chemicals, regardless of their proportional contribution to the total agonist activity, and regulates on the basis of such concerns. It would be more protective of the public health to determine acceptable concentrations for each type of response, regardless of the origin of the inducing agent, and issue advisories or regulations accordingly.

Abstract Chemical pollution of anthropogenic origin such as heavy metals, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls are some of serious threats to the environment. Their main sources are industry, transport, and agriculture. Chemical substances pollute the air, water and soil, where ultimately most of them reach and accumulate. Soil constituent involved in the adsorption of impurities is organic matter (OM), the structure of which can be divided into three fractions: humic acids (HA), fulvic acids (FA) and humin (H). The impact of pollution with OM allows the presence of active functional groups, among others, -OH, -COOH, -NH3, -OCH3. Strongly adsorbed contaminants are not available for soil microorganisms.

<abstract> <p>Naturally Occurring Radioactive Materials (NORMs) and Technologically Enhanced NORMs (TENORMs) are among the principal sources of radiation exposure for humans and for the environment. Therefore, the assessment of the impact of NORMs and TENORMs waste on human health is a key issue for their management and for acceptance of disposal sites. The radiological doses to workers and public due to TENORMs disposal depend on the waste inventory, on the usage of the site during operational activities and post closure phase and on the presence of dwelling areas in the vicinity of the disposal site. In the present study it is presented a methodology to preliminary assess the feasibility of a disposal of TENORMs, mainly constituted by phosphate sludges, originated from phosphoric acid industry activities. The hypothetical case study here presented is inspired by a real case study. Different possible scenarios have been considered. The potential doses to workers and to the public on-site have been estimated by the use of the TSD Dose and the RESRAD on-site codes both during the production life cycle of the site and once it ended. Sensitivity analyses were conducted to evaluate the impact of some key parameters, such the coverage thickness and wind velocity, on potential risk for workers and public.</p> </abstract>

Recently the condition of agriculture in Indonesia needs to be addressed. Soil fertility getting damaged due to chemical fertilizer that is not impartial. In addition, the impact of excessive use of synthetic pesticides can cause damage to the ecosystem. Control of plant diseases using biological agents began getting attention because of public concerns due to the use of synthetic chemical pesticides. Biological agents are microorganisms,  both  naturally  occurring  such  as  bacteria,  fungi,  viruses  and protozoa, as well as the results of genetic engineering that are used to control plantpests. Madrasah Diniyah Jumapolo, Karanganyar, has pioneered the manufacture of biological agents to support organic farming although on a small scale. Community service activities undertaken to provide assistance in the improvement of the production process  and  management  improvements.  The  technology  developed  is  the  use  ofbiological pesticides agent isolated from Beauveria bassiana and Trichoderma sp. As a natural insecticide and fungicide. The activities received support from the madrasa and expressed successfully produce biological agents in the proper packaging. In addition to the consumption of madrasa and nearby farmers, pesticide product ofbiological agents is also sold to the public. The selling of products will increase the development of organic farming to produce healthy food also will gain additional income for the madrasa.

The application of modified agricultural wastes for removing polycyclic aromatic hydrocarbons (PAHs) from water is gaining a growing interest. However, most modified methods using synthetic chemicals may cause secondary pollution. To overcome this limitation, in this study, a rhamnolipid modified corn stalk (RL-CS) for the removal of phenanthrene (PHE) from aqueous solution was prepared using a rhamnolipid-enhanced acid modification method. RL-CS with higher surface area and lower polarity exhibited higher PHE removal efficiency than that of raw corn stalk (RCS). The adsorption kinetics of RL-CS fitted well with pseudo-second-order kinetics (R2 &gt; 0.999). Sorption coefficients and carbon-normalized sorption coefficient of RL-CS were 4.68 and 2.86 times higher than that of RCS. Sorption process of RL-CS was nonlinear. Meanwhile, the sorption was an exothermic process and could occur spontaneously. The present study demonstrated that biosurfactant-modified biosorbent RL-CS may be of great potential for the removal of low concentrations of PAHs from the contaminated waters.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.

The Swiss Armed Forces (SAF), as part of a democratic system, depends on legitimacy. Democracy, legitimacy and the public are closely connected. In the public sphere the SAF need to be visible; it is where they are controlled and legitimated by the citizens, as part of a deliberative discussion in which political decisions are communicatively negotiated. Considering this, the meaning of political communication, including the SAF’s communication, becomes obvious as it forms the most important basis for political legitimation processes. Social media provide a new way for the SAF to communicate and interact directly with the population. The SAF’s social media communication potentially brings it closer to the people and engages them in a dialogue. The SAF can become more transparent and social media communication may increase its reputation and legitimacy. To measure the effects of social media communication, a survey of the Swiss internet population was conducted. Based on this data, a structural equation model was defined, the effects of which substantiate the assumption that the SAF benefits from being on social media in terms of broadening its reach and increasing legitimacy values.

The paper analyses specific features of sociological data circulation in a public space during an election campaign. The basic components of this kind of space with regard to sociological research are political actors (who put themselves up for the election), voters and agents. The latter refer to professional groups whose corporate interests are directly related to the impact on the election process. Sociologists can also be seen as agents of the electoral process when experts in the field of electoral sociology are becoming intermingled with manipulators without a proper professional background and publications in this field. In a public space where an electoral race is unfolding, empirical sociological research becomes the main form of obtaining sociological knowledge, and it is primarily conducted to measure approval ratings. Electoral research serves as an example of combining the theoretical and empirical components of sociological knowledge, as well as its professional and public dimensions. Provided that sociologists meet all the professional requirements, electoral research can be used as a good tool for evaluating the trustworthiness of results reflecting the people’s expression of will. Being producers of sociological knowledge, sociologists act in two different capacities during an election campaign: as analysts and as pollsters. Therefore, it is essential that the duties and areas of responsibility for professional sociologists should be separated from those of pollsters. Another thing that needs to be noted is the negative influence that political strategists exert on the trustworthiness of survey findings which are going to be released to the public. Using the case of approval ratings as an illustration, the author analyses the most common techniques aimed at misrepresenting and distorting sociological data in the public space. Particular attention is given to the markers that can detect bogus polling companies, systemic violations during the research process and data falsification.

Subject. This article discusses the methodological features of Russian Accounting Standard (PBU) 18/02 Income Tax Accounting when using the balance method to account for deferred taxes. It considers whether the clarification of permanent tax differences is justified, and it analyzes in detail the features of accounting for temporary differences and offers a visual and descriptive method for determining and correlating them in accounts. Objectives. The article aims to justify the reason for linking permanent tax differences to such accounting categories as Income and Expenses. It also aims to develop a methodological toolkit that simplifies the perception of the balance method and demonstrates the procedure for determining temporary differences. Methods. For the study, we used the methods of analysis, synthesis, observation, comparison, and other general scientific methods. Results. The article justifies the clarification of permanent differences from the position of accounting categories. It offers an original approach that helps visually classify temporary differences. The formalization of the balance method helped identify the logic of its reflection in accounting statements. Conclusions and Relevance. To ensure that accounting is not distorted due to the impact of taxation, it is necessary to develop a unified conceptual framework, as well as develop existing methods and introduce new ones that do not contradict the public concept of interaction between accounting and tax accounting. The research results are intended for training, scientific and practical activities of specialists in the field of accounting and audit, as well as students studying under this program, in order to study the features of applying the balance method for accounting for deferred taxes.
