Evaluation of integral exposure energy load on aural analyzer of miners

The individual exposure integral noise load on workers before the beginning of hearing impairment was determined for a group of 20 male miners who had worked with drilling equipment and harvesters for 8 to 20 years before the onset of the disability. Results show that the total exposure energy load of about 4 kw x h sq m, obtained by miners in the examined group, resulted in occupational injury to the auditory organ (cochlear neuritis) in 75% of the cases. The equivalent energy level of noise computed according to the date of total energy load is roughly 99 db A, which significantly exceeds the permissible amount of 85 db A. There is a correlation (r = 0.77) between the integral exposure energy noise on the aural analyzer in the degree of increase in the total threshold for the mean speech range

Macrofauna of hydrobionts in the Gubkinsko-Starooskolsky mining area: the case of the Oskolets River

The areas of iron ore mining and processing are characterized by a high level of anthropogenic load. Among them is the Starooskolsko-Gubkinsky mining area of the Belgorod region. A certain indicator of the influence caused by mining enterprises on the adjacent territories is the state of hydrobiocenoses in surface watercourses located in the zone of their direct influence. The Oskolets River was adopted as a model; its middle reach is located in close proximity to the Lebedinsky mining and processing plant (LMPP), from where the drainage waters of the quarry are discharged. The aim of the work was to differentiate the contribution of this enterprise to the general pollution of the river using bioindication method

Impact monitoring of mining enterprises of Kursk magnetic anomaly on hydro ecological river situation of the Belgorod region

The results of contrastive analysis of hydrochemical state of surface water bodies exposed to the impact of mining enterprises, by way of example of small rivers of the Belgorod region, according to the results of exploration carried out in the years 2009-201

2013 Political Discussions in Foreign Affairs Committee of British Parliament on Iranian Nuclear Issue

The debate on Iran’s nuclear program in the Foreign Affairs Committee of the British Parliament, held in February 2013, in anticipation of the resumption of negotiations between Iran and the “six” of international mediators, is considered. Particular attention is paid to the position of experts invited to the meeting: representatives of academia, public organizations, military analysts. The high expert and analytical level of the meeting, which made it possible to develop effective political initiatives is noted. The most pressing issues raised during the parliamentary debates are considered. It was proved that both the deputies and the invited experts considered the further development of Tehran’s nuclear program dangerous. The authors dwell in detail on theways to resolve the Iranian nuclear problem, recommended by experts at a committee meeting: from increasing sanctions pressure to finding ways of a diplomatic settlement. The relevance of the study is due to the fact that the Iranian nuclear problem continues to be a toxic factor in the Middle East region. The novelty of the study lies in the fact that the attempt is made to reveal the position of the British Parliament members and leading experts on Iranian foreign policy. It is concluded that the political position expressed by the deputies and experts in the parliament testified to the readiness of the parties to negotiate and develop a consensus on the Iranian nuclear program

Combined MASS-DIMM instrument for atmospheric turbulence studies

Several site-testing programs and observatories currently use combined MASS-DIMM instruments for monitoring parameters of optical turbulence. The instrument is described here. After a short recall of the measured quantities and operational principles, the optics and electronics of MASS-DIMM, interfacing to telescopes and detectors, and operation are covered in some detail. Particular attention is given to the correct measurement and control of instrumental parameters to ensure valid and well-calibrated data, to the data quality and filtering. Examples of MASS-DIMM data are given, followed by the list of present and future applications.Comment: Accepted by MNRAS, 11 pages, 8 figure

The results of introduction of East Asian origin flowering plants in the southwest of Central Russian upland

The article is devoted to the study of the results of introduction of East Asian origin flowering plants, growing in the dendrological collection of Belgorod Botanical Garden. The most important ecological and biological characteristics of the plants were studied. The estimation of the growth and development nature of introduced species, according to their resistance to the complex of unfavorable factors, was carried ou
