Based on the research of the chemical erosion intensity in the upper course of Tamnava, the appearance of its negative value has been found. Further researches, that enclose the lower course, confirmed this fact. This research opened the important question about the causes of this phenomena. Analytical method eliminated all expected causes and led to conclusion that the reason for this should be found by using the more precise research of the mineralisation of the precipitations. It was necessary to continue the measurings of the precipitation mineralisation in the greater number of locations and in the wider time period, as well as in the different meteorological conditions, and after that to establish the subordination between the amount of precipitations and the entered TDS. Only after these additive researches we could be able to find out the relation between ''entry'' and ''exit'' and to find out the intensity of the chemical erosion in this, and in the other river basins. For now, we are able only to find out the carrying of TDS, as well as the reduction of the chemical evacuation for the non - carbonated part of the basin (corrected value).

Erosion Intensity

Land use change in all river basins leads to changes in hydrologic response, soil erosion, and sediment dynamics characteristics. Those changes are often viewed as the main cause of accelerated erosion rates. We studied the impact of land use changes on soil erosion processes in one of the watersheds in Montenegro: the Miocki Potok, using this watershed as a pilot river basin for this area. We simulated responses of soil erosion processes by using a process-oriented soil erosion Intensity of Erosion and Outflow (IntErO) model, with different settings of land use for the years 1970, 1980, 1990, 2000, 2010, and 2020. The model provides fast, effective, and affordable insight into the effects of land use change on soil erosion processes. Testing of the applied procedures was important for the further establishment of watershed management methodologies at the national level, for the other 300 river basins of Montenegro. For the current state of land use, calculated peak discharge for the Miocki Potok was 364 m3 s−1 (2020)–372 m3 s−1 (1970) for the incidence of 100 years, and there is a possibility for large flood waves to appear in the studied basin. Real soil losses, Gyear, were calculated at 13680 m3 year−1 (2020) and specific 333 m3 km−2 year−1 (2020). A Z coefficient value of 0.439 (2020) indicated that the river basin belongs to destruction category III. The strength of the erosion process was medium, and according to the erosion type, it was mixed erosion. According to our analysis, the land use changes in the last 50 years influenced a decrease in the soil erosion intensity for 14% in the Miocki Potok River Basin. Further studies should be focused on the detailed analysis of the land use changes trends with the other river basins at the national level, closely following responses of soil erosion to the changed land use structure, and effects of plant-and-soil interaction on soil erosion and sediment dynamics.

We consider revolutions and civil war involving an incumbent, a challenger, and the population. Revolutions are classified into eight outcomes. In four outcomes incumbent repression occurs (viewed as providing sub-threshold benefits such as public goods to the population). Accommodation occurs in the other four outcomes (benefits provision above a threshold). The incumbent and challenger fight each other. The incumbent may win and retain power or else lose, thereby causing standoff or coalition. In a standoff, which is costly, no one backs down and uncertainty exists about who is in power. In a coalition, which is less costly, the incumbent and challenger cooperate, compromise, and negotiate their differences. If the population successfully revolts against the incumbent, the challenger replaces the incumbent. Eighty-seven revolutions during 1961–2011, including the recent Arab spring revolutions, are classified into the eight outcomes. When repressive, the incumbent loses 46 revolutions, remains in power through 21 revolutions, and builds a coalition after 12 revolutions. When accommodative, the incumbent loses seven revolutions and builds a coalition after one revolution. The 87 revolutions are classified across geographic regions and by time-period.

ABSTRACTShare of Indonesia's export value of natural rubber in the international market is almost always below Thailand, which is one of the competiting countries. The others countries began to become a threat to Indonesia because their exports share of natural rubber showed an increasing. This indicates that there is intense competition in the international market. As a country with the largest plantation area in the world, Indonesia should be superior. But this can be an opportunity to be able to compete in the world market so it is important to be managed more deeply so that it can create competitive advantages that can increase competitiveness. This study aims to determine the position of the competitiveness of natural rubber exports for the three countries of ITRC in the international market. The analytical method used is dynamic RCA. The results showed that all products of natural rubber coded HS 400110, 400121, 400122, 400129 and 400130 were experiencing a decline in growth in the export share of the three countries of ITRC : Indonesia, Thailand and Malaysia, but the market demand conditions for these products were declining in that time period.

Attempts have been made to eradicate the tsetse flies G. morsitans and G. swynnertoni from two blocks of savannah woodland situated in the Central Province of Tanganyika.The insecticides were applied from aircraft. Coarse aerosols were used, with mass median diameters of approximately 90 microns; droplet diameters varied from 4 microns to 250 microns approximately.Eight applications of insecticides were made at intervals of two weeks. Each application was carried out at a nominal dosage of 0·25 gallons per acre, which was equivalent to 0·20 1b. per acre of the p, p'isomer of DDT or 0·03 lb. per acre of the γ isomer of BHC.In the area treated with DDT it is possible that both species of flies were eradicated for a short period, but small populations were re-established there by immigrant flies. In the other block the reduction was not so great, but it is not considered that this was due to a lesser effectiveness of the BHC, but to a combination of circumstances that led to less effective applications.Some general observations are made upon the use of aircraft for this sort of work, particularly in connection with the effect of meteorological conditions.

Gambus Paser music is one among traditional perfoming arts belongs to Paser tribe. Contextually, gambus Paser performing art cannot be detacted from its socio-culural since it geographically affects the characteristic of that cultural music. Generally, the culture of Gambus Paser music has its various values according to its various geographical dispositions. Geographically varied characteristic of Gambus Paser music is reflected on the interpretation of the music especially on the style of pentengan (picking technique) and the lyric of Gambus song. Gambus Paser music is also characteristically identified by the use of that pentengan style. On the other hand, coastal area also affects Gambus Paser characateristic which tends to be expressive and dynamic. Conceptually speaking, this research is qualitative research with descriptive analytical method. This research focuses on Gambus Paser performing art as the cultural (music) literacy enhancement. The purpose is to analyze the form of Gambus Paser performance as Paser cultural literacy. The result shows that literature related to Paser art is still hardly found, while on the other hand, we have also found how potential this performance as sustainable literacy and identity enhancement for Paser community to welcome the Indonesian capital relocation to East Borneo. A concrete step which is taken is to documenting and disseminating the Gambus Paser performance to create a cultural literacy and a sustainable traditional art.

Hourly Distribution

Several interesting observations have recently been made regarding the existence of maximum hours of mortality and the allied subject of recurrent variations in the activity of physiological function. During the present year an important contribution to the literature of the subject has been made by Dr. James Finlayson, of Glasgow, who in a couple of papers published, the one in the Transactions of the Philosophical Society of Glasgow for 1873-4, and the other in the Glasgow Medical Journal for April 1874, has supplemented and summarized Schneider's searching examination into the statistics bearing on the subject, tabulated the results of Mr. West Watson, a Glasgow predecessor in the study of vital problems, and collected the scattered statistics contained in the important contributions to the literature of this interesting enquiry. In an independent summary, showing the hours at which the greatest number of deaths occur in several Glasgow institutions, Dr. Finlayson determines the comparative cumulative mortality during successive hours of the same day, and during groups of hours collocated on account of some marked contrasts in meteorological conditions and physiological activity. As far as regards deaths from chronic diseases, the results obtained by Dr. Finlayson are confirmatory of those of Caspar and the summarized statistics of Schneider. They show a notably increased mortality during ante-meridian hours, as compared with those of the afternoon and evening, and especially a determinate maximum between 4 A.M. and noon. With regard to acute diseases, the figures of Dr. Finlayson show that in them the morning rise is nearly if not altogether equalled by a second rise in the extent of hourly mortality occurring in the afternoon. He accounts for this divergence from the general results, by referring to the influences exerted by the post-meridian rise in temperature which characterizes that group of diseases, as a means of determining in them the modification of their hours of maximum mortality.

The research object. The hydrological characteristics of the Gunt and Vanch rivers belonging to the Southwestern and Central climatic zones of the Pamirs and are tributaries of the transboundary Pyanj River are considered. Long-term average values of temperature and precipitation as the main factors affecting the formation of river flows are determined for the period 1944–2016. The state of glaciation in the basins of the respective rivers is estimated. Goal. A comparative assessment of the influence of climatic features and mountain orography on the formation of river flows. Determination of the trend of changes in the climatic conditions of the Gunt and Vanch river basins at different periods of more than 70 years (1944–2016). Research methods. Generalization, systematization of meteorological and hydrological characteristics and determination of their change compared with the base period 1960–1990. Statistical processing of meteorological and hydrological data and establishing a trend of changes in climatic and hydrological characteristics using a differentiated method. Research results. It is shown that the nature of changes in hydrological characteristics, namely the flow of rivers in different climatic zones of the Pamir can differ significantly. On the example of two rivers (Gunt and Vanch) - tributaries of the transboundary Pyanj river, it is shown that the trend of change in the flow of the Gunt river differs from the Vanch river due to the state of glaciation of the river basin. To explain the results the meteorological conditions of the respective river basins and their possible impact on river hydrology were studied. Conclusion. The hydrological characteristics of the Gunt and Vanch rivers in the Pamirs taking into account the meteorological conditions of the respective river basins show that a key factor in improving the state of glaciation and reducing degradation processes, as well as achieving positive trends in the mass balance of glaciers is the presence of sufficient air mass in the glaciation zone. Naturally, this is the key to ensuring a sufficient amount of runoff.

Individuals exposed to both job loss and marital dissolution are likely to be highly disadvantaged, having experienced stresses and losses in the two primary domains of life. Moreover, recent literature finds that exposure to one event tends to increase risk of the other. However, next to nothing is known about the size or composition – or changes therein – of the divorced/separated and unemployed (DSU) subpopulation. Using large, nationally representative, repeated cross-sectional datasets extending back to 1984, we aim to fill this gap for the UK. We give a descriptive account of the prevalence and social distribution of DSU, and of the cross-sectional association between its two component states: among which groups, by education and gender, does being either divorced/separated or unemployed most strongly imply a heightened risk of also being the other, and how has this changed over time? We find stable and strong educational inequality in DSU, while the gender gap has narrowed and recently closed. The association between the two states is stronger among men; has weakened strikingly over the time period we consider, for both men and, especially, women; and is educationally stratified among men but not women. Contrary to expectations, higher-educated men in one of the two states are most likely to also be in the other. Possible explanations and further questions are discussed. In particular, we highlight the possibility that over this time period the divorced/separated have become more like the general population, rather than a negatively selected subgroup among whom unemployment is a particular risk.

Railway route from entity border to Maglaj is on corridor V of railways that connects Adriatic seawith European Union countries. More precisely, it is on the railway Samac – Sarajevo that was builtduring the fifties. From Doboj to Zenica exist two tracks, one built in 1947. and the other thirty yearslater. In time, the railway worn out, since it was not maintained properly during its exploitation, soallowed train speed is 40 km/h. Reconstruction of railway had previously started on sections with aimto achieve the level of train speed to 120 km/h.Terrain research in order to overview quality of material on which the railway is laid, and immediateenvironment that has effect on railway route, were conducted by sections, from which section km103+500 – Maglaj is one of the most important considering characteristics of the terrain on which theroute passes. Research along railway route were conducted by using research trial pits from both sidesand in between tracks, to depth of entry in basic soil. Depth of research works is different for old andnew track, considering the way of construction in time period of 30 years. Beyond narrow corridor ofrailway route research of characteristics of the terrain were not conducted, because of inability toaccess due to mining. Results of terrain and laboratory tests showed geotechnical characteristics ofmaterial, based on which were given quality improvement measures for deposited materials, and basefor reconstruction of railway.

Hybrid moth orchid (genus Phalaenopsis) is one of the most popular ornamentals in Indonesia. It has beautiful and long-lasting flowers, but cultivating this orchid is still become a challenging issues due to the need of specific condition to grow and long time period to re-blooming. Plant growth regulators (PGR) (i.e. Benzyladenine (BA)) has been widely documented as a flower-inducing substance in several orchids. However, the optimal concentration and its mechanism in inducing flower-stalk bud and re-blooming is still unclear. This research aimed to study the effects of BA application in the form of lanolin paste on hybrid Phalaenopsis flower-stalk buds. We conducted this study using completely randomized design with four replications at the greenhouse laboratory Faculty of Agriculture University of Lampung on August to December 2018. We divided the orchid into 5 group of BA concentration (0, 1000, 1500, 3000, or 6000 ppm). The sheath of the fourth or fifth buds of the flowers were carefully opened, then it smeared with BA. The percentage of bud break into flower spike or keiki, length of shoots or spike and number of open flowers were recorded until 10 weeks of observation. The results showed that, neither of the buds under the control treatment (without BA), 1000 ppm nor 1500 ppm BA broke and grew into keiki or spike. On the other hand, application of BA at 3000 ppm or 6000 ppm successfully induced 100% flower spikes on the buds treated. No keiki was formed in all buds treated. In addition, treatment of the buds with 6000 ppm BA produced longer flower spikes as well as more open flowers. We conclude that the application of BA (minimal 3000 ppm) successfully induced flower spike of  hybrid Phalaenopsis.
