Nowadays there is a tendency towards increasing of anthropogenic pollution in the atmospheric air in the large cities. Therefore, important measures have to be taken for the improvement of the atmospheric environment. In order to optimize the quality of air in the city and reduce emissions from stationary and mobile sources, it is important to predict of the state of the atmospheric air of the city, which is based on the analysis of the characteristics of adverse weather conditions conducive to the accumulation of harmful impurity in a lower (ground) layer of air. The paper identifies and analyzes the conditions in the Cherkassy city (Ukraine) for the period of 2011–2015, provides correlation and regression analysis of air pollution index with adverse weather conditions (the multiple correlation coefficient R = 0.55–0.87). The current research shows that the maximum number of days with adverse weather conditions is in autumn (77.20±4,96) and the lowest number is in spring (58.60±4.40), the greatest number of days matching several adverse weather conditions were found in January and October (4.80±0.20 and 4.60±0.24, respectively). Recommendations to reduce the content of harmful impurities in the atmospheric air of the city are suggested.

Detailed Picture

This article examines the travel behavior of middle-class women in Dhaka, the capital city of Bangladesh and one of the world's largest and most densely populated cities. In particular, we focus on women's use of non-motorized rickshaws to understand the constraints on mobility for women in Dhaka. Primary research, in the form of an empirical study that surveyed women in six neighborhoods of Dhaka, underpins our findings. Our quantitative and qualitative data presents a detailed picture of women's mobility through the city. We argue that although over 75 percent of women surveyed chose the rickshaw as their main vehicle for travel, they did so within a complex framework of limited transport options. Women's mobility patterns have been further complicated by government action to decrease congestion by banning rickshaws from major roads in the city. Our article highlights the constraints on mobility that middle-class women in Dhaka face including inadequate services, poorly maintained roads, adverse weather conditions, safety and security issues, and the difficulty of confronting traditional views of women in public arenas.

Introduction. Climate change around the world determines the relevance of the study of its effects on the human health. Nowadays, due to the development of modern medical science, the methods of evidence-based analysis of negative impact of the environmental factors on the public health are being widely implemented into preventive medicine. Their use should make it possible to quantify the various risks with high confidence and to manage them effectively. Material and methods. The weather conditions of the territory of Vladikavkaz for a 15-years period (2001-2015) have been studied. On the basis of the data from the primary medical documentation of emergency medical care (EMC) for the same period, the health status of the adult population in the city has been studied. The impact of the meteorological elements under the study on the frequency of seeking EMC was estimated using the relative (RR) and population risks (Rpop) values. Results. For the city of Vladikavkaz (according to the medical classification of weather conditions), high air humidity is typical for 65% of the days in a year, low air velocity (less than 3 m/s) - 77% of the days in a year. Inter-day fluctuations in temperature and atmospheric air pressure, exceeding the optimal levels for the human body, are recorded more than in 30% of the days in a year. Discussion. The city of Vladikavkaz is characterized by windless, wet weather, with frequent inter-day fluctuations in temperature and atmospheric air pressure, which corresponds to the clinically irritating and acute types of weather. Conclusion. The calculations of the relative and the population risks of impact of meteorological changes on the developing of urgent cardiovascular conditions in the population of Vladikavkaz showed RR of combining two unfavourable weather factors to be of 1.081 (p <0.0001), and the Rpop increases by more than 3600 additional EMC calls due to cardiovascular pathology.

The problem of air pollution in Almaty city in stagnant weather conditions is considered. Such conditions are so frequent, because the city is located at the foothills of the mountain range of Ile Alatau. The WRF-Chem complex model is used for the analysis and allows a high-detail simulation both of the atmospheric circulation and the transport of various pollutants, taking into account their chemical transformations. The results of modeling meteorological processes are compared with observational data. The main attention is paid to the calculation of the sulfur dioxide plume emitted by the pipes of the coal-fired CHP-2. The simulations showed that regional latitudinal wind, whose direction regularly changes to the opposite one, dominates in the northern part of the city atmosphere. During such periods and under unstable atmosphere stratification conditions, the plume dissipates and pollutants penetrate into the surface layer. In some areas, the concentration of SO2 significantly exceeds sanitary standards.

And Performance

It is a well-known fact that the 1989 Exxon Valdez disaster caused the escort towing of laden tankers in many coastal areas of the world to become compulsory. In order to implement a new type of escort towing, specially designed to be employed in very adverse weather conditions, considerable changes in the hull form of escort tugs had to be made to improve their stability and performance. Since traditional winch and ropes technologies were only effective in calm waters, tugs had to be fitted with new devices. These improvements allowed the remodeled tugs to counterbalance the strong forces generated by the maneuvers in open waters. The aim of this paper is to perform a comprehensive literature review of the new high-performance automatic dynamic winches. Furthermore, a thorough analysis of the best available technologies regarding towline, essential to properly exploit the new winches, will be carried out. Through this review, the way in which the escort towing industry has faced this technological challenge is shown.
