Pesticides, despite their side effects, are still being used in almost every agriculture, horticulture, maintaining municipal greenery in urban areas and even in home gardens. They influence human life and health and the functioning of entire ecosystems, including inanimate elements such as water and soil. The aim of the study was the evaluation of the suitability of sewage sludge in improving the quality of soil treated with a non-selective herbicide-glyphosate, applied as Roundup 360 SL. A pot experiment was conducted with the use of two arable soils (MS and OS), which were amended with sewage sludge (SS), glyphosate (GL) and sewage sludge with glyphosate (SS+GL). Soil samples were taken after 24 h, 144 h and 240 h and total phosphorus (TP) content (TP), total number of bacteria/fungi, activity of dehydrogenases (Dha), acidic phosphatase (Acp), alkaline phosphatase (Alp), genetic biodiversity of bacteria/fungi using the terminal restriction fragment length polymorphism method were determined. The application of SS and GL to OS caused an increase in Acp (approximately 35%) and a decrease in Alp activity (approximately 20%). Additionally, GL may influence on an increase in the number of fungi and the decrease in the number of bacteria. In soil with SS+GL increase in the fungal diversity in MS and OS was also observed. Moreover, a positive between TP and the number of bacteria and the activity of phosphatases correlation was reported. The obtained results indicate that analyzed sewage sludge could be potentially applied into soil in in situ scale and could constitute a valuable reclamation material.

Subject. The article considers functioning and development of process flows of transportation and logistics system of a smart city. Objectives. The study identifies factors and dependencies of the quality of human life on the organization and management of stream processes. Methods. I perform a comparative analysis of previous studies, taking into account the uniquely designed results, and the econometric analysis. Results. The study builds multiple regression models that are associated with stream processes, highlights interdependent indicators of temporary traffic and pollution that affect the indicator of life quality. However, the identified congestion indicator enables to predict the time spent in traffic jams per year for all participants of stream processes. Conclusions. The introduction of modern intelligent transportation systems as a component of the transportation and logistics system of a smart city does not fully solve the problems of congestion in cities at the current rate of urbanization and motorization. A viable solution is to develop cooperative and autonomous intelligent transportation systems based on the logistics approach. This will ensure control over congestion, the reduction of which will contribute to improving the life quality of people in urban areas.

To improve the water quality of Lake Yuehu, a water diversion from the Han River was conducted in July 2008. However, an unexpected Microcystis bloom occurred in the lake after water introduction. Water and sediment samples were collected from Lake Yuehu and the variation of chemical and biochemical parameters, as well as the phytoplankton community, were analyzed during the water diversion to assess its effect and to clarify the mechanism leading to the Microcystis bloom. The nitrogen (N) concentration was increased and phosphorus (P) concentration decreased in Lake Yuehu after receiving water from the Han River, which had a high loading of N and a low loading of P. These conditions may benefit the growth and dominance of non-N2 fixing Microcystis, as it may not have suffered from P limitation during our study because it did not produce extracellular phosphatase, which worked as an indicator of P deficiency, as evidenced by the in situ enzyme-labelled fluorescence. Notably, the sediment Fe (OOH)~P content significantly decreased in Lake Yuehu; this pulsed release of P from the sediment might have sustained the Microcystis bloom. Based on our results, algal blooms may occur as a consequence of conducting water diversion projects to improve water quality.

A intensificação da urbanização na ultima etapa da modernidade gerou inúmeros problemas relacionados à qualidade e condições de vida humana nas cidades. No âmbito dos países não desenvolvidos estes problemas tomam maior magnitude que nos desenvolvidos, gerando consideráveis desafios à gestão socioambiental das áreas urbanas. O problema da qualidade da água e da gestão dos recursos hídricos aparece como um dos mais graves da sociedade contemporânea, notadamente em países como o Brasil, cujos rios urbanos encontram- se altamente degradados em sua grande maioria. A associação entre os perigos, os riscos e a vulnerabilidade socioambiental, quando enfocados na perspectiva da interação entre os recursos hídricos e a sociedade urbana, torna-se muito importante, constituindo-se no enfoque central do presente texto. Nesse contexto, a questão da escassez de água no ambiente urbano brasileiro é abordada e a problemática é explorada. Abstract URBAN SOCIOENVIRONMENTAL RISKS AND VULNERABILITY: A PERSPECTIVE FROM THE WATER The intensification of the urbanization on the Modernity generated innumerable problems related to the quality and conditions of human life in the cities. Concerning the undeveloped countries these problems take greater magnitude that in the developed ones, generating considerable challenges to the socioenvironmental management of the urban areas. The problem of the quality of the water and the management of the hydrical resources appears as one of the most serious of the contemporary society, notably in countries as Brazil, whose urban rivers are highly degradeted. The association between the dangers, risks and socioenvironmental vulnerability, focused in the perspective of the interaction between the hydrical resources and the urban society, becomes very important, consisting the central approach of the present text. In this context, the question of the water scarcity in the Brazilian urban environment is analised and the problematic one is explored.

Abstract In this work, the anaerobic digestion of three microalgae (Chlorella sp., Nannochloropsis sp., and Scenedesmus sp.) and their residues, resulting from the oil extraction process and the in situ transesterification reaction for biodiesel production, using two inoculums (sewage sludge and poultry manure) for biogas production was investigated. It was found that the biogas production from digestion of oil-extracted microalgae residue with sewage sludge reached values ​​similar to those obtained with raw microalgae (around 500 NL kg−1 VS). Both the volume of biogas generated from the microalgae residue from the extraction process of its oil and the quality of the biogas produced reflect the value of this residue to be valorized by anaerobic digestion. This approach based on a biorefinery concept and focusing on the anaerobic digestion process could be a key technology for energy production from biomass.

Introduction. Amazons is a group of women who are extremely brave and valiant in their social organization, who support each other against the heavy adversary that has put their lives in their way- breast cancer. The activities of associations facilitate adaptation to the new health situation of these women. An indispensable aspect of women after a mastectomy is their quality of life. The concept of quality of life is a multidimensional term covering every sphere of human life at every stage. Aim. The aim of the work was to assess the quality of life of women after mas-tectomies associated with the Amazon group. Material and methods. The study examined 103 women aged ≥ 20. More than three quarters of respondents lived in urban areas and one in three women lived in rural areas. The WHOQOL-BREF questionnaire is used to assess the quality of life and is a standardised tool for assessing the quality of life of both healthy and sick people. Results. Women after mastectomy affiliated with the Amazon club accept their appearance and health, which translates into an overall quality of life. Conclusions. Patients after the sparing procedure assess their quality of life at the highest level, while women after bilateral mastectomy at the lowest level. The extent of the support provided by loved ones has a significant impact on self-assessment in terms of quality of life satisfaction. Awareness of cancer negatively affects the mental sphere. Active professional persons after mastec-tomy were given the opportunity to return to work, which positively affected the quality of life.

Human life is full of risk. In general one or few family members are earning to run the existence, and most of the family members are depending on the earning members. In the present world, a human may lose his life by many ways such as, by age, by accident, by diseases and so on no one compensate by anybody else. One can succeed an insurance company only when it retain their existing customers and attract new customers by providing good insurance services. For this purpose understanding of purchase behaviour of customers in the insurance sector is very important to improve the quality of existing schemes and to introduce new schemes in insurance products to attract new customers and it will lead to enhancing their market. Tamilnadu is one of the biggest states in India. There are 32 districts in the state of Tamilnadu, among them Cuddalore district is one of the important districts, since the number of villages is more in the region and most of them depend on agriculture for their livelihood. Awareness about insurance policies among rural people is lower than people in urban areas. The researcher will specifically consider life insurance products in the insurance sector. Hence the researcher has intended to assess the awareness level of rural people in the study area on various aspects of life insurance products. The researcher will analyse the purchase behaviour of rural people in the study area towards life insurance products.

The environment and the economy are basic and inseparable elements. The environment is the locus and support for the activities of human life. These activities are related to the creation and supply of resources necessary for the economy. They generate large amounts of waste, while the load capacity of the environment is limited. When economic operations go beyond certain limits, then the environment cannot sustain them. This could lead to economic crisis on a global scale. The problem is how to protect the environment, maintain economic operations and improve the lives of human beings, or in other words, find the ways to harmonise environmental factors with the needs of the economy. Vietnam and other developing nations are facing serious problems of environmental degradation, especially in urban areas. Many solutions have been tried, of which the use of economic instruments has received much attention on the part of the government and leaders of Vietnam. This article focuses on the use of economic instruments in urban environment management in Vietnam. The objectives of this article are to explore how economic instruments are being used for urban environment management and to point out the issues and difficulties emerging in the process of using this tool to control environmental pollution and to improve the quality of the environment.
