The Kremenets Mountains are the unique region of the Volhyn-Podillia Upland, which is situated at the northeastern part of Gologory-Kremenets low mountainous edge of Podillia to the east from Ikva River valley. There are intensively dissected relief, wide growth of deep gullies and ravines, phenomena of slope recession are widespread as well as karst and karst-suffosion processes, etc. here. Ancient people settled the territory of Kremenets Mountains a long time ago. This is evidenced, in particular, by the Paleolithic site Kulychivka in Kremenets, where people lived from 40,000 years ago. Kremenets Mountains descend towards the plain of Small Polissya by a steep slope up to 100 m and more. There are picturesque landscapes and a significant number of attractive residual mountains (Bozha, Stizhok, Chercha, Bona, Unias, etc.) here. It is not surprising that this stunning area is often called the Ukrainian Switzerland. On the territory of the Kremenets Mountains over the basis of erosion, the deposits of chalk of the Upper Cretaceous age are widely developed. In the chalk, there are numerical nodules of mainly grey and black flint (flint in Ukrainian is kremin, hence the name Kremenets) in sizes up to 0.3–0.4 m, which often lie in separate layers. High-quality flint served as a raw material for the production of tools by ancient people. The peaks of the Kremenets Mountains are armoured with layers of Sarmatian oolithic limestones and sandstones lying horizontally with a capacity of 10 m or more. Oolithic limestones and sandstones determine the wide development of the structural relief in the Kremenets Mountains, and rocky outcrops of oolithic limestones often determine the formation of exotic cliffs – unique natural monuments. Kremenets Mountains are incredibly rich in objects of historical and cultural heritage, which is especially true of the picturesque Kremenets. The combination of natural (geological and geomorphological) and historical and cultural objects makes the Kremenets Mountains promising for the development of tourism. The article presents original maps of geotouristic, historical and cultural objects of the Kremenets Mountains and the environs of Kremenets town. Maps are built on geological and hypsometric bases. The geotouristic potential of the research area is analysed. Key words: Kremenets Mountains, Podolian Upland, geotourism, geotouristic objects, historical and cultural objects, residual mountains, flint, the Palaeolithic.

Abstract The constant growth of the population increases the demands on raw material resources, which is reflected in increasing pressure on the environment. The impact of mankind on the environment is nowadays an increasingly acute problem, which is being addressed by the governments of individual countries, not only the EU, through legislative interventions. The most addressed areas are the issue of production and subsequent waste management. Waste production in the world has been growing for a long time, which causes considerable problems for individual countries. Each country is currently looking for the optimal way of waste management to reuse it as secondary raw material. In this paper, we analysed twenty-eight EU countries in terms of production and waste management and found significant differences between countries. We looked for factors that lead to different results between countries in the production and management of waste, based on the population, the size of the country to the indicators of living standards, and legislation applicable to those countries.

UKM (small and medium enterprises) in the Tembesi Tower, Tembesi sub-district, are not developing well. This is indicated by the low turnover obtained by each UKM (small and medium enterprise) in 1 month. customer expectations. New products must be made so that these small and medium businesses can survive and continue to exist. The new product must have a distinctive and good quality so that the product positioning is clearer and able to compete with other products on the market. This service activity aims to provide a solution to this by creating a new product in the form of a dab soap that is safe for health and environmentally friendly. Some soaps circulating in the market only prioritize cleaning power, but the chemical content in the soap is harmful to health and the environment. The impact of conventional soap on health is irritation of the skin which, if left for a long time, the irritation will turn into eczema. In addition, conventional soap also harms the environment because the raw material for soap comes from petroleum which is difficult to be broken down by bacteria. Community service activities are carried out in the form of coaching. The service team expects to increase the income and advantages of UKM (small and medium businesses) in the Tembesi Tower and to be able to create jobs or open a business with a revolutionary cream soap product design.

The research focuses on the problem of military-political instability in the Democratic Republic of the Congo experiencing continued armed conflict for a long time. Dozens of illegal armed groups both Congolese and foreign origin continue to destabilize situation in the eastern part of the country causing humanitarian disasters. Due to governmental weakness, economic backwardness, chronical lack of finance resources, interethnic conflicts, all-round and widely spread corruption of the authorities, the Congolese government at the moment is not able to overcome scores of problems including the problem of security. Assistanceprovided to the DRC by itspartnerssuch as, first of all, the former metropolitan country Belgium, as well as the USA, Great Britain, the Europe Union and China works only in favourof these country-donors. They are attracted by rich Congolese natural resources which the DRC remaining one of the poorest countries in the world cannot turn to advantage to the full extent because of its economic backwardness. In exchange for so-calleddevelopment programmes, expensive strategic raw material (such as coltan, wolfram, casseterit, cooper, gold, niobium, and other) is being extracted and exported from the country, in addition, often on the inequivalent basis. This is taking place for the reason that numerous mines and open-cast mines are being controlled by different illegal armed groups and not by the central government. Therefore, it turns out that in the context of a military-political crisis, for so-called partners it is more beneficial to pursue their own interests. Furthermore, western ideologists arouse "separatism-oriented" theories similar to "balkanization", in other words, a breakdown of this giant country into several independent states. The Congolese are tremulous to this issue, they try to counter such approachs and defend the territorial integrity of the DRC. However, it is not an easy task. The impediment is unsettled relations with neighbouring countries - Rwanda, Uganda and Burundi which for tens of years exploit illegally natural resources of the DRC and try to lay hold of frontier Congolese territories.

Groundwater is an important part of water storage and one of the important sources of agricultural irrigation, urban living, and industrial water use. The recent launch of Gravity Recovery and Climate Experiment (GRACE) Satellite has provided a new way for studying large-scale water storage. The application of GRACE in local water resources has been greatly limited because of the coarse spatial resolution, and low temporal resolution. Therefore, it is of great significance to improve the spatial resolution of groundwater storage for regional water management. Based on the method of random forest (RF), this study combined six hydrological variables, including precipitation, evapotranspiration, runoff, soil moisture, snow water equivalent, and canopy water to conduct downscaling study, aiming at downscaling the resolution of the total water storage and groundwater storage from 1° (110 km) and to 0.25° (approximately 25 km). The results showed that, from the perspective of long time series, the prediction results of the RF model are ideal in the whole research area and the observations wells area. From the perspective of space, the detailed changes of water storage could be captured in greater detail after downscaling. The verification results show that, on the monthly scale and annual scale, the correlation between the downscaling results and the observation wells is 0.78 and 0.94, respectively, and they both reach the confidence level of 0.01. Therefore, the RF downscaling model has great potential for predicting groundwater storage.

ABSTRACT        The production of pig manure waste potentially pollutes the soil, water and air. One of the most effective processing a waste treatments is through composting. The composting process takes a long time if not assisted by the activator as decomposers of organic materials in order to accelerate the composting process. Activators such as local microorganism (MOL) contain macro nutrients, micro and active microorganism that potentially decomposed organic materials, growth stimulants and pest/disease control agents such as to help speed up the composting process. This study aims to determine the C/N ratio of optimal raw materials for composting of pig manure and vegetable waste, determining the effect of adding local microorganism (MOL) to the length of time of composting and determining the effectiveness of business from composting of pig manure and vegetable waste based on the calculation of B/C ratio.        This research uses quantitative approach with experiment method. The first stage is the preparation of the raw material which is divided into three groups : composition 1 with 75% (pig manure) and 25% (vegetable waste), composition 2 with 50% (pig manure) and 50% (vegetable waste) and then composition 3 with 25% (pig manure) and 75% (vegetable waste). Furthermore, the best raw material composition was treated with variations of MOL addition of A (100 ml), B (300 ml), C (500 ml) and D (without MOL).        The results showed that the composition of the best raw material mixture was a mixture composition of 25% (pig manure) and 75% (vegetable waste) with a C/N ratio of 38.95. The effect of MOL addition indicates that the greater MOL volume the faster to composting process. The quality compost with addition of MOL has C/N ratio levels is (16,30), N-total (1,65%), P tersedia (8043,02 ppm), K tersedia (8857,40 ppm), Fe (1,87%), Mn (0,09%) Zn (480 ppm) in which that value meets the SNI 19-7030-2004. Based on analysis of B/C ratio obtained result of 1.04 where the value is approaching criteria B/C ratio more than 1.00 which means compost business feasible to be developed.   Keywords : Pig manure, MOL, time of composting, composter, B/C ratio

The spontaneous periurban, peripheral, non-communal or anarchic spontaneous habitat in Tunisia is a recent phenomenon that began as early as independence and has continued to increase to the present day. This type of habitat is a new configuration of urban space in the sense that it expresses a set of signs and symbols that refers to a specific culture and a certain relationship that is established between social actors and their space. In this context, the question could be asked: why is this type of habitat perceived as peripheral, illegal and marginalized? Couldn't it be the focus of a sensual daily life?  The space of these outlying neighbourhoods is the place of interaction through which each inhabitant writes his scenario through his actions, values and daily practices to forge an urban identity both individual and collective. This is what we have seen from fieldwork in two suburbs of the city of Sfax: Ben Saida and Erryadh district where poverty and marginality were experienced as a creative experience. The interactionism and sociology of everyday life thus constitute our theoretical framework through which we will use observation and audiovisual recording as investigative techniques to take a close look at the spontaneous behaviours of social actors and to deeply analyze their daily conversations of the populations of the outlying districts of Sfax.  The interactionism and sociology of everyday life thus constitute our theoretical framework through which we will use observation and audiovisual recording as investigative techniques to take a close look at the spontaneous behaviours of social actors and to deeply analyze their daily conversations of the populations of the outlying districts of Sfax.

The daily experience is therefore rich in meaning and symbols and it deserves a long time to make it the raw material of our sociological analysis.

This review discusses the challenges within the research area of modern biomass fractionation and valorization. The current pulping industry focuses on pulp production and the resulting cellulose fiber. Hemicellulose and lignin are handled as low value streams for process heat and the regeneration of process chemicals. The paper and pulp industry have therefore developed analytical techniques to evaluate the cellulose fiber, while the other fractions are given a low priority. In a strive to also use the hemicellulose and lignin fractions of lignocellulosic biomass, moving towards a biorefining concept, there are severe shortcomings with the current pulping techniques and also in the analysis of the biomass. Lately, new fractionation techniques have emerged which valorize a larger extent of the lignocellulosic biomass. This progress has disclosed the shortcomings in the analysis of mainly the hemicellulose and lignin structure and properties. To move the research field forward, analytical tools for both the raw material, targeting all the wood components, and the generated fractions, as well as standardized methods for evaluating and reporting yields are desired. At the end of this review, a discourse on how such standardizations can be implemented is given.
