The explosive global change in the emissions of Sulphur dioxide (SO2) over the decades have brought about tremendous effects in the regional as well as global scale in the composition and quality of air that we breathe. The global SO2 emission peaked in the 1970s, decreased until 2000 and has risen to peak again mainly as the result of increased globalization in developing countries. The global estimation is surprisingly low but the regional output of SO2 is high. The main hotspots being in East Asia Countries. The Sulphur aerosols not only impacts the animals’ health, but those of the ecosystems at large. SO2 contributes to global warming, ozone depletion, acid rain, smog etc. that has brought disastrous environmental conditions. WHO recommends a maximum exposure of not more than 0.5 ppm for around 24 hours’ span. SO2 reacts with other gases to form sulphate particles, constituent of particulate matters i.e. PM 2.5 concentrations, the exposure to which causes skin, respiratory, reproductive failures and cardiovascular ailments. This study, as such, is meant to bring into light the sources of SO2 and its harmful effects on health and environment at large. Air pollution is a major issue with adverse effects prevailing over the globe at present.

Abstract Starting in 1988, with the installation of the first broadband (BB) instrument in Italy, the Mediterranean Very Broadband Seismographic Network (MedNet) program established a backbone network of BB stations of the highest quality in the Mediterranean Sea countries. The Mediterranean region is characterized by relevant and frequent seismicity related to its complex tectonics, due to the convergence of two major plates, Africa and Eurasia, and the involvement of other minor plates, as the Adriatic plate. Therefore, the MedNet project became a scientific research infrastructure of excellence, able to fill the gap of regional coverage when the availability of seismic BB instruments was still scarce. The main characteristics of the MedNet network are the highest quality of the seismographic instrumentation at remote sites and very low level of anthropogenic noise with stable conditions of pressure and temperature. After 30 yr of recordings, the MedNet program has proven that the early adoption of very BB instruments in selected sites have been the best choice. A large number of studies benefited from MedNet data, as seismic source computation and Earth structure reconstruction, at local and global scale. We present a concise overview of the contribution given by MedNet data in the last three decades to motivate and financially support the existence of this valuable infrastructure, and to further maintain this project.

Agency theory explanations for corporate political activity assume that managers distort resource allocation to invest in political connections to pursue personal benefits. While distorted resource allocations yield poor earning quality, we expect that companies with efficient governance may curb this opportunistic behavior. We used matching procedures to identify the effects of financing political campaigns on the earning quality of the firm. We assembled an original panel of listed firms in Brazil from 1998 to 2013. We found that firms that donated to electoral campaigns had a lower earning quality than nondonor firms. Firms with superior corporate governance instruments were able to reduce the harmful effects on earning quality. These results support the tenets of agency theory in explaining why firms engage in politics.

Tinnitus is a pervasive public health issue that affects approximately 15% of the United States population. Similar estimates have also been shown on a global scale, with similar prevalence found in Europe, Asia, and Africa. The severity of tinnitus is heterogeneous, ranging from mildly bothersome to extremely disruptive. In the United States, approximately 10-20% of individuals who experience tinnitus report symptoms that severely reduce their quality of life. Due to the huge personal and societal burden, in the last twenty years a concerted effort on basic and clinical research has significantly advanced our understanding and treatment of this disorder. Yet, neither full understanding, nor cure exists. We know that tinnitus is the persistent involuntary phantom percept of internally-generated non-verbal noises and tones, which in most cases is initiated, by acquired hearing loss and maintained only when this loss is coupled with distinct neuronal changes in auditory and extra-auditory brain networks. Yet, the exact mechanisms and patterns of neural activity that are necessary and sufficient for the perceptual generation and maintenance of tinnitus remain incompletely understood. Combinations of animal model and human research will be essential in filling these gaps. Nevertheless, the existing progress in investigating the neurophysiological mechanisms has improved current treatment and highlighted novel targets for drug development and clinical trials. The aim of this review is to thoroughly discuss the current state of human and animal tinnitus research, outline current challenges, and highlight new and exciting research opportunities.

The aim of this paper is to present the results of measurements, on the quality of internal and external environment, carried out during the cruise of the tall ship STS Fryderyk Chopin. The cruise took place between 16th and 30th September 2017 as part of the scientific seminar of the Warsaw University of Technology (WUT) on the Wave, addressed to students of the WTU. After leaving the port of Edinburgh, crossing the North Sea, the Danish straits, stops in Copenhagen and Kołobrzeg, the tall ship reached Szczecin after two weeks. The measurements carried out on the deck included the temperature and relative humidity of the indoor air in three cabins and the men’s bathroom. In two cabins, the CO2 concentration was measured additionally. The outdoor temperature, relative humidity and concentration of PM 1.0, PM 2.5 and PM 10 were also measured. The obtained results allowed to assess the quality of the internal environment in accordance with the standards and to analyze the effectiveness of the mechanical ventilation system. Measurements of particulate matter have shown significant differences between outdoor air quality in the open sea and in ports or near major shipping routes. It turned out that the impact of emissions from passing ships using diesel engines is clearly visible.

SUMMARY Female aging is a process that involves hypoestrogenism time, the individual impact on each woman, and what we can do as experts to reduce morbidity and provide quality of life. This natural process in the female life cycle has been of concern to women after menopause. Changes in different biophysical and psychosocial aspects, and their individual experiences, have repercussions on the lives of patients seeking specialized and multidisciplinary support to reduce the harmful effects of prolonged hypoestrogenism. Overweight and obesity, inadequate living habits and the presence of multi-morbidities cause damage to the quality of life and impact the functional capacity. Behavioral prescription and hormone therapy are among the treatments given to ease symptoms and reduce morbidity. A better understanding of these factors can help identify groups that require more care after menopause.

Abstract. The prevalence of coccidiosis diseases of various animal species has a global scale, so this problem has attracted the attention of veterinary specialists around the world. The purpose of this study was to study the specific features of the species composition and laboratory diagnostics of eimeriosis in young ruminants and to evaluate the effectiveness of treatment and prevention when using drugs from different groups. The material for the study was goats and calves. The research was carried out on the basis of two farms of the same agricultural holding in the Sverdlovsk region. Diagnostics was performed based on clinical and laboratory studies. Results of the study. The main pathogens in the goat breeding complex in goats of different ages were identified: the main causative agent of coccidiosis in 120-day-old goats was Eimeria arloingi, which accounted for 54 % of all detected oocysts in the samples. Eimeriosis occurred as a mixed invasion of Eimeria arloingi with Eimeria ninaekohlyakimovae (33 %) and Eimeria intracata (13 %). Eimeria arloingi (68 %), in 21-days-old goats – Eimeria ninaekohlyakimovae (32 %). Eimeriosis caused by Eimeria bovis was detected in 30-days-old calves (100 %). The article describes the results of using various anticoccidial drugs in the treatment and prevention of eimeriosis. A comparative evaluation of the therapeutic effectiveness of known coccidiostatics is given. The economic efficiency of different groups of drugs was evaluated. The scientific novelty lies in the fact that the morphological and quantitative assessment of parasitocenoses in eimeriosis in young ruminants was carried out. A comparative evaluation of the effectiveness of various traditional remedies and a new drug for the treatment of eimeriosis in calves and goats was carried out. Conclusion. Not all of the drugs used have the same therapeutic effectiveness both in terms of treatment time and the quality of elimination of the etiological factor.

Abstract. A global seabed sediment map has been developed since 1995 to provide a necessary tool for different needs. This project is not completely original since it had already been done in 1912 when the French hydrographic Office and the University of Nancy produced sedimentary maps of the European and North American coasts. Seabed sediments is one of the last geographical domains which can’t benefit of satellite data. Without this contribution, sediment maps need to use very old data mixed with the new ones to be able to reach the goal of a global map. In general, sediment maps are made with the latest available techniques and are replaced after a few decades, thus generating new cartographic works as if all the previous efforts had become useless. Such approach underestimates the quality of past works and prevents to have maps covering large areas. The present work suggests to standardize all kind of sedimentary data from different periods and from very different acquisition systems and integrate them into a single product. This process has already been done for bathymetric data of marine charts, we discuss in this article of the application of this method at a global scale for sediment data.

AbstractLichens epiphytic on olive trees were used as biomonitors of sulphur dioxide pollution in La Spezia (Northern Italy). The method adopted was designed to avoid subjectivity at all stages, from the sampling strategy to data analysis. Thus, lichen data are expressed by an index that does not depend on any sensitivity scale; data analysis relies on multivariate methods of classification and ordination, and the pollution maps have been produced by automatic mapping programmes. The index, based on the frequency of species within a sampling grid, showed a very high statistical correlation with pollution data measured by recording gauges. The results of classification and ordination indicate that Parmelia caperata is the species with a distribution best related to the lichen index. The quality of air pollution data obtained from biomonitors is discussed.

The efficiency and quality of the vision is one of the key challenges of a modern life. The goal of the paper is to reveal a need of vision therapy and preventive vision improvement in a general education school. The aim of vision therapy is to improve vision and efficiency of the vision and to find ways to further improve quality of vision. Vision therapy is usually individually tailored to each and every person in order to clarify the issues. Worldwide, doctors caring for patients’ vision, lots of attention devote for improvement of eye prophylaxis treatment during special training. Vision therapy is used to address these issues: insufficiency of accommodation, problems of presbyopia and amblyopia, convergence or divergence, dyslexia, after Strabismus surgery and others. Permanent eye exercise not only improves vision, but also prevents the eyes from harmful effects of environment. Key words: science education, vision, vision therapy.
