Viviparus viviparus L. is the most numerous alien species of the Novosibirsk reservoir. In some parts of the reservoir V. viviparus creates settlements with a very high density. After the death of mollusks in the bottom sediments and on the banks of the reservoir, large areas of accumulation of empty shells are formed. Due to their strong structure, the shells are poorly decomposed and can serve as a generalized indicator of the state of the mollusk population over a long time. We analyzed the size and age characteristics of the V. viviparus shells in thanatocenoses of the Novosibirsk reservoir coast. Empty shells of river snails were collected on the shores of the middle (near the village of Chingis, Ordynskoye and in the Karakansky Bay) and the lower (near the village of Borovoye, Bystrovka, Leninsky and in the Berdsky Bay) parts of the Novosibirsk Reservoir in May, 24–26, 2018. Shells height and width were measured with an electronic caliper with an accuracy of 0.1 mm. Age of mollusks was determined by the marks of a winter growth stop on the shell. It is shown that in the thanatocenoses of the middle part and in the bays of the reservoir, shells of young mollusks (the second and third years of life) prevailed. In the lower part of the reservoir, the coastal thanatocoenosis contained larger shells of adult mollusks (fourth and fifth years of life). In general, the most of V. viviparus individuals in the Novosibirsk reservoir die before they reach the age limit. It is suggested that the premature death of most river snails can be caused by significant seasonal fluctuations in the water level of the reservoir, during which the littoral is drained.

Overall the evolution process of the Red River Delta based on the maps and historical data resulted in a fact that before the 20th century all the Nam Dinh coastline was attributed to accumulation. Then started the erosion process at Xuan Thuydistrict and from the period of 1935 - 1965 the most severe erosion was contributed in the stretch from Ha Lan to Hai Trieu, 1965 - 1990 in Hai Chinh - Hai Hoa, 1990 - 2005 in the middle part of Hai Chinh - Hai Thinh (Hai Hau district). The adjoining stretches were suffered from not severe erosion. At the same time, the Ba Lat mouth is advanced to the sea and to the North and South direction by the time with a very high rate.The first task of the mathematical modeling of coastal line evolution of Hai Hau is to evaluate this important historical marked periods e. g. to model the coastal line at the periods before 1900, 1935 - 1965; 1965 - 1990; 1990 - 2005. The tasks is very complicated and time and working labors consuming.In the paper, the primarily results of the above mentioned simulations (as waves, currents, sediments transports and bottom - coastal lines evolution) has been shown. Based on the obtained results, there is a strong correlation between the protrusion magnitude and the southward moving of the erosion areas.

In the 1930s, the primary schooling rate in Turkey was significantly low compared to the European states. Ninety percent of the population lived in villages without any schools and teachers. Therefore, promoting primary education was addressed as an issue concerning villages in Turkey. The seeds of the intellectual infrastructure in the emergence of institutes were sown at the beginning of the 20th century, during the Ottoman rule. To train teachers for villages, Village Teacher Training School [Köy Muallim Mektebi] was founded in 1927 and Village Instructor Training Course [Köy Eğitmen Kursu] in 1936. However, these initiatives were not sufficient in terms of quality and quantity. Village teacher training experiences, new education, and work school trends of Europe were analyzed by Turkish educators, opinions of foreign and Turkish experts were received, and the Village Institutes [Köy Enstitüleri] project was carried into effect based on the realities of Turkey. The first Village Institutes opened in 1937. They were established in a restricted area, with a limited budget, and a non-common curriculum until the Village Institute Law was promulgated in 1940. On April 17, 1940, the law prescribing their establishment was approved by the parliament. The number of the Village Institutes, which spread over the Turkish geography evenly, reached 21 by 1949. The period between 1940 and 1947 was when the Village Institutes were most productive. Learning by doing and principles of productive work were embraced at the Village Institutes. The curriculum consisted of three components: general culture, agriculture, and technical courses. In addition to their teaching duties, the primary school teachers that graduated from the Village Institutes undertook the mission of guiding villagers in agricultural and technical issues and having them adopt the nation-state ideology in villages. World balances changing after the Second World War also affected the Village Institutes. In 1946, the founding committee of the Village Institutes were accused of leftism and had to leave their offices for political reasons. After the founding committee stepped aside, the Village Institutes started to be criticized by being subjected to the conflict between left-wing and right-wing. Following the government changeover in 1950, radical changes regarding the curricula, students, and teachers of the institutes were made. Making the Village Institutes unique, the production- and work-oriented aspects were eliminated, and the institutes were closed down in 1954 and converted into Primary School Teacher Training Schools. Although the Village Institutes existed only between 1937 and 1954, their social, economic, and political effects were felt for a long time through the teachers, health officers, and inspectors they trained.

The Continental intercalary groundwater is highly sought for its water as resources hugely mobilized in Northern Sahara. A very high flow rate and output pressure characterizes this underground water. It amounts from 50 to 400 l.s-1 for the flow, and from 5 to 40 bar for pressure. A survey of the Northern Sahara Aquifer System was essential to prove the existence of this potential. This energy appears into the artesian form, which remains very considerable for a very long time in most drilling. We have realised that this energy is immense, as well as the expanded volume of the groundwater, and the importance of its use in agriculture. Unfortunately, this potential remains untapped to this day and the energy of this water is completely neglected. Several turbo generator and/or inverted pump (PATs) integration tests were undergone. The new concept of reflection with respect to the environment and sustainable development has led us to structure our work towards the extension of this potential in order to extract the exploitable energy.

IntroductionDuring 2008 Russian Federation realized major aggression against its direct neighbor, the sovereign republic of Georgia. It was Russia's attempt to crown its long time aggressive politics by force, using military forces. EMS physicians from Tbilisi went to the Gori district on August 8 at first light, 14 brigades were sent. At noontime of August 8, their number was increased up to 40. 6 brigades of disaster medicine experts joined them as well.ResultsDestination site for the beginning was the village Tkviavi, where a military field hospital was assembled and a Military Hospital in Gori. Later 6 brigades were withdrawn towards the village Avnevi. During fighting, wounded victims were evacuated from the battlefield, where initial triage was done. Evacuated victims were brought to the military hospital where the medical triage, emergency medical care and transportation to Gori military hospital or to Tbilisi hospitals was done. A portion of the wounded was directly taken to Gori military hospital and later to different civil hospitals in Tbilisi. Corpses were transported to Gori morgue as well. On August 9, the emergency care brigades and field hospital left Tkviavi and moved to the village Karaleti, then to Gori. On August 12, the occupied territory was totally evacuated by civil and military medical personnel. Although withdrawal of wounded was done on following days. Up to 2232 military and civil persons were assisted by EMS brigades during war period (8–12 August), from them 721 patients were transported among which 120 were severely injured.ConclusionClose collaboration between military and civil EMS gave the system opportunity to work in an organized manner. On the battlefield prepared military rescuers were active taking out wounded victims to the field or front-line hospitals from which civil emergency care brigades transported them to Tbilisi hospitals. Only 3 fatalities occurred during transportation.

The article analyzes the local version of veneration of St. Stephen of Perm among the Nivshera’s Komi. The microlocal folklore tradition of the village Nischera (Komi Republic) is geographically far from the place of residence of the first bishop of Perm and the main area (Lower Vychegda and Vym) of the spread of traditions about a religious saint, who was called the “Zyryansky Apostle”. Meanwhile, the chapel (now lost) in honor of the saint and the saved life icon in the small village Rusanovskaya helped preserve the memory of a religious figure in popular culture. The post-temple life of the icon is amazing: relatives of the shrines who saved from death made a vow to hold home services. According to the established model in the Nivshera tradition off-temple services began to be held also before the reproduction of the icon Stefan Perm. The work attempted to compare scenarios and strategies for conducting home worship in two places. To some extent, the future of such practices will depend not only on the capabilities of the guardians of the icon and the presence of successors of this matter, but also on the socio-cultural situation of the village and interaction with the Orthodox Church. To some extent, the future of such practices will depend not only on the capabilities of the guardians of the icon and the presence of successors of this matter, but also on the socio-cultural situation of the village and interaction with the Orthodox Church. The cult veneration of Stefan Perm in the Nivshera folklore tradition is evidenced by recorded oral stories about a saint who visited the Vishera District, climbing a boat along the river, expelled rats for a long time, saved the village from fire, and provides general patronage to the village Rusanovskaya.

Land susceptibility to degradation is characterized by the loss of topsoil due to erosion which is considered as a threat to agricultural productivity. Information about land sensitivity to erosion is crucial in determining the appropriate soil and water conservation techniques to avoid land degradation. This study, which was located in the Gandul Sub-Watershed, aims to analyze the level of land sensitivity to erosion in highland agricultural areas. Data analysis was carried out spatially using land system and land-cover maps. Soil and water conservation efforts were determined based on the land function and sensitivity. The land sensitivity to erosion in the Gandul Sub-watershed was categorized into 3 levels which were moderate (3.9%), high (95%), and very high (0.8%). There were various directions for Gandul Sub-Watershed management by considering the level of sensitivity of the land and the function of the area. Creating a ridge is one of the soils and water conservation practices that has been implemented for a long time by local communities as a soil erosion prevention.   Keywords: agriculture, erosion, Gandul, sensitivity

The article summarizes the definition of the term “hikikomori”, analyzes the situation of quarantine restriction: its essence and features of the impact on adolescence. Peculiarities of manifestation of hikikomori markers at adolescence are determined. We consider the studied phenomenon in the system of approaches like a way to meet needs, as a set of manifestations of syndromes of a new era, as a psychological defence mechanism, as a psychological state and process. Depending on the intensity of markers, we divide hikikomori into counter-dependent, poorly adaptable and interdependent, super dependent. The parameters that determine the level of manifestations of hikikomori include antisocial solitude at home, antisocially with leaving the house, selective society. The levels of manifestation of hikikomori include physical, emotional, social. Quarantine restrictions, as unusual living conditions that require forced solitude, selfisolation can be a factor that encourages the emergence of markers of hikikomori in adolescents. Such people have a shift in activity in cyberspace and at night, inseparable stay with the gadget (during meals, in the bathroom, in the toilet, etc.). Neglect of the organization of life (do not clean the bed after sleep, do not clean the room for a long time, do not change clothes during the day and wear night pyjamas around the clock, neglect a healthy diet, eat outside the regime, mostly fast food, etc.). In communication with others, they show irritability with the desire to avoid contact and solitude in their room. Also, at such a person, disorganization of educational activity hastily is observed. It is difficult for them to organize the learning process; they show procrastination (postponement of tasks). If the classes are as videoconferencing, they do not include video and microphone. They are away from contact with the group and the teacher, even if they need contact for feedback, they ignore it. An empirical study of the susceptibility to hikikomori markers in adolescents revealed that about 40% of subjects have a high susceptibility to hikikomori markers, and almost 11% of young men – very high.

Rehabilitation works were carried out on boreholes in the Dunkwa Mining town in the Central Region of Ghana. These works were carried out because the boreholes had lost their original yields due to clogging, corrosion and encrustation and had been abandoned for a long time. The cost of drilling a new well and assessing the productivity of the well is $4,500 which is more expensive that carrying out rehabilitation works which is cheaper, about $800. Also, the initial yields of the boreholes were very high according to the feasibility report which is not a common characteristic of the rocks in the area. Camera inspection followed by rehabilitation, pre and post pumping tests were carried out to assess whether there has been an improvement in their yield after the exercise and that the yield obtained will be adequate for a water supply design. Results show that all the boreholes had an improvement in their yields (57.19 - 259.80 %) after the rehabilitation. It can therefore be concluded that rehabilitation is effective in restoring boreholes to their original yields. Organisations drilling boreholes to communities can take advantage of rehabilitation of the existing boreholes located in the communities which are high yielding, thereby reducing project implementation cost.

A small group of richly decorated spurs has been known for a long time for their characteristic non-ferrous metal covering as well as massive bronze or brass thorn points. Most of them have been found in in the states of Hamburg and Schleswig-Holstein. They are so similar that they could have been manufactured, if not in the same workshop, at least in the same region. The embossed metal sheath, reminiscent of the Late Slavic technology of sheath fittings, could indicate a the Slavic craft tradition. The latest find from a deserted village of Kastaven near Sähle, Oberhavel district in northern Brandenburg, sheds new light on this group of objects. The Kastaven spur has been found in the central area of the settlement which existed between the early 13th and the 15th centuries, in the vicinity of ruins of a church or a churchyard. The spur was probably lost at the village foundation phase, in the early 13th century. This context is of importance to the disputed chronology of the entire spur group, dated back to the late 12th and the early 13th centuries. The finds in Hamburg, Holstein, Eastern Mecklenburg and Northern Brandenburg indicate contacts between the élites in the southwest of the Baltic, related to migrations of petty nobility within the German Eastern Settlement or a communication network of the Slavic Leaders in the Abodrite/Mecklenburg cultural area.
