The paper presents data on distribution and abundance of the steppe marmot in the territory of two northern raions (districts) of Donetsk Oblast — Sloviansk and Lyman. Research was carried out in 2011 to 2020. In total, 284 burrows were recorded belonging to 25 home ranges. The largest marmot settlements in the studied territory comprise up to 29 burrows. The number of burrows on a home range varies from 1 to 29, in average 11.4. The total abundance of the steppe marmot is over 100 animals in Lyman Raion and over 20 individuals in Sloviansk Raion. The marmot population in Sloviansk Raion is re-introduced—370 individuals were released in 1991—, while the population in Lyman Raion is of rather natural origin. The optimal habitats for the steppe marmot are chalk slopes of southern exposure, where its home ranges consist of the highest number of burrows. Permanent inhabited burrows are located in the middle part of the slopes, whereas the vast majority of protective burrows are below the slope and at the bottom of the beams. All settlements are located on the right bank of rivers. The largest marmot settlements are confined to poor Cretaceous and, less frequently, sandy soils with sparse vegetation. The natural marmot population in Lymansky Raion shows a tendency to slow dispersal and population growth, while the abundance of the re-introduced population is much smaller than the number of released animals. The density of the natural population remains low despite the many uninhabited areas suitable for the marmots. Settlements are formed as separate disconnected groups. New marmot settlements are often formed in places of old settlements. Natural populations are more stable compared to re-introduced ones and the density of natural steppe marmot population is also higher. Poaching, especially in Sloviansk Raion, is a major threat to the marmot, as well as the overgrowth of the steppe by shrubs due to decrease in grazing. Marmot settlements on the Cretaceous steppes are almost insensitive to reduced grazing. In Lyman Raion, fires and ploughing of balka slopes, too, negatively affect the species. Development of epizootics is unlikely given the low density of the marmot. The marmot populations can be preserved and can even expand their range in the region if sufficient protection measures are provided.

To a free people, the very word “censorship” always has been distasteful. In its theory, it runs counter to all democratic principles; in practice, it can never be made popular, can never please anyone.Everything the censor does is contrary to all that we have been taught to believe is right and proper. The Post Office Department, for example, has two proud mottoes: “The mail must go through,” and “The privacy of the mail must be protected at all hazards.” But censorship stops the mail, it invades the privacy of the mail, it disposes of the mail as may seem best. The same thing holds true in the publishing business. Censorship limits the lively competition and free enterprise of reporters. It relegates many a scoop to the waste basket. It wields a blue pencil—both theoretical and actual—on news stories, magazine articles, advertisements, and photographs. Censorship also enters the radio industry, where it may edit scripts and in some cases stop entire programs.Yet even the most vociferous critics of the principle of censorship agree that in war-time some form and amount of censorship is a necessity. It then becomes not merely a curtailment of individual liberty, but a matter of national security. It is one of the many restrictions that must be imposed on people fighting for the right to throw off those restrictions when peace returns.

The “go/no-go” decision for a candidate property, i.e., whether or not to actually acquire the site, choose the brand (flag), build and operate the hotel, requires the explicit consideration of the interconnectedness of the many myriad elements affecting the property's potential profits. The many facility design decisions (number and mix of rooms, capacity for F&B operations etc.) as well as other strategic choices (e.g., size of marketing program, level of service aimed for) must recognize the site's competitive features and interactions with the above. Also, the particular design and operational features for a given property will affect its different revenue streams, fixed and variable costs, efficiency and profits. The authors consider developers contemplating acquiring a given site, choosing a brand, building and operating a new hotel. They offer a normative approach for this type of decision which arrives endogenously at possibly attractive options for the brand, design and strategic choices for the site. The final decision as to which option to actually use, if any, should be based on subjecting the above identified scenarios, as well as others, to traditional feasibility analyses where judgment and expert opinion are applied. The authors' implementable approach integrates a “best practices” benchmarking methodology with regression analysis to yield a mathematical programming optimization model. A key advantage of this approach lies in its contrast to conventional approaches for site selection which often ignore the more detailed design and strategic choices. The approach deals explicitly with the complex interfaces between marketing and operations management as the endogenous site and competitive environmental factors interact with the endogenous brand and facility design choices. By identifying attractive options to be further explored (that might otherwise be overlooked), several types of errors are avoided: i) an incorrect “go/no go” decision could be recommended for the site in question; ii) even if the right decision to proceed is made, the forecasted level of annualized profits could be in error, leading to an incorrect priority for the activity; iii) the incorrect brand and facility design choices could be made for the site. Other key advantages of the suggested approach are that 1) various substitution possibilities (between more or less capital, labor, materials etc.) are considered; 2) not only is the best brand and configuration identified, but also a ranking of other brands is available if the “best” brand is not available; 3) the “best practices” at other specific sites (which serve as the basis for the recommendations) are identified, thereby enabling management (possibly through site visits) to isolate the actual cultures, processes and procedures to be transported and emulated at the candidate site. This paper illustrates the approach for two different sites.

In the entry on ‘Fascism’ published in 1932 in the Enciclopedia Italiana, Benito Mussolini made a prediction. There were, he claimed, good reasons to think that the twentieth century would be a century of ‘authority’, the ‘right’: a fascist century (un secolo fascista). However, after 1945 the many attempts by fascists to perpetuate the dreams of the 1930s have come to naught. Whatever impact they have had at a local level, and however profound the delusion that fascists form a world-wide community of like-minded ultranationalists and racists revolutionaries on the brink of ‘breaking through’, as a factor in the shaping of the modern world, their fascism is clearly a spent force. But history is a kaleidoscope of perspectives that dynamically shift as major new developments force us to rewrite the narrative we impose on it. What if we take Mussolini’s secolo to mean not the twentieth century, but the ‘hundred years since the foundation of Fascism’? Then the story we are telling ourselves changes radically.

Ovarian polytene chromosomes from eight populations of Anopheles quadrimaculatus in the southeastern United States were observed for chromosomal polymorphisms. Two sibling species, species A and B, each with intraspecific inversions, were distinguished. Species A correlates with the previously published standard maps for salivary gland and ovarian nurse-cell polytene chromosomes. Species A was found at all eight collection sites, and five of these populations also contained species B. Three inversions on the right arm of chromosome 3 were observed in species A. Species B contained a fixed inversion on the X chromosome, one fixed and one floating inversion on the left arm of chromosome 2, and one fixed and one floating inversion on the right arm of chromosome 3. The fixed inversion on the X chromosome makes this the best diagnostic chromosome for distinguishing species A and B. An unusual dimorphism in the left arm of chromosome 3, found in both species A and B, contained two inversions. The heterokaryotypes, as well as two distinct homokaryotypes, were seen in all of the field populations. Intraspecific clinal variations in the frequencies of the species A inversions were noted. The Florida populations were practically devoid of inversions, the Georgia and Alabama populations contained some inversions, and the Arkansas population was mostly homozygous for two of the inversions. The phylogenetic relationships of species A and B to the Maculipennis complex (Nearctic) are discussed.Key words: Anopheles, inversion, populations, chromosome polymorphism, phylogenetics.

Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed ∼ 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operative management of ruptured bilateral PA aneurysms is feasible and effective.

This paper examines features of the demographic structure of natural populations of a rare representative of the steppe flora Astragalus cornutus Pall. (Fabaceae). The rarity of the species makes it necessary to include it in the Red Books of the Russian Federation and some steppe regions. In the Samara Region, species populations require additional protection in connection with the peculiarities of biology and ecology, a significant anthropogenic load on communities, and a reduction in the number of habitats. We studied the features of the structure of populations in the Samara Trans-Volga Region. A total of 84 cenopopulations were surveyed, tendencies of population change, features of demographic and spatial structure were revealed. The structure of populations is affected by the ecological and phytocenotic conditions of the environment and anthropogenic factors. The replacement and recovery of individuals in A. cornutus populations is slow. The ontogenetic structure of populations has a fluctuation dynamics. Assessment of the studied geographical populations by L.A. Zhivotovsky efficiency criterion (2001) showed that they are all mature. Specific cenopopulations of A. cornutus are aging (5%) and old (8%). The average density of individuals is about 3 individuals/m. The average effective density is 2,4 individuals/m, the largest - 4,1, the smallest - 1,3. The condition of all studied populations (even in a satisfactory state) on the territory of the Samara Region causes alarm. Populations of the species in the region need additional protection measures.

The article describes the activities of the Pokrovsky monastery-hospital in Kiev, created by the efforts of the Grand Duchess Alexandra Petrovna (1838-1900), who took the monastic vows in 1889 under the name Anastasia. The monastery became widely known in the late XIX - early XX century for the highly skilled medical aid provided to the population since its inception up to the events of 1917. It was a unique complex of medical settings located in the same area and equipped with modern medical equipment comparable with the many World’s clinics of that time. In this monastery-hospital, pilgrims with different diseases who came at Pokrovsky monastery in Kiev were provided the required qualified, affordable medical care. Thanks to the Grand Duchess Alexandra Petrovna, her attentive attitude to all the latest innovations, novel treatment methods were developed and introduced to the work of monastery medical settings. In addition, she was able to create a special atmosphere and goodwill towards the sick. But, being engaged in devising new methods of providing medical care to patients, she was able to create a special and inviting atmosphere with respect to the patient. With the ever-increasing circle of her organizational and economic activities, being in charge of the monastery-hospital problems of great importance, Grand Duchess reserved the right to nurse her patients. She worked by vocation, at the behest of the soul. Her example of selfless labor in the monastery medical settings where monastic sisters held the medical staff responsibilities for the patients care was important for all of the staff. Her assistants - Sisters of Charity - she fostered by her own example of selfless aid to a sick person. This favorable work atmosphere was very effective helping cure the sick.

It is possible that running training for many years in athletics affects athletes' running patterns and sole structure. The main aim of this study is to examine the effect of maximal force applied to the floor area and contact area of the athletes with related to mid-distance training for athletics. 18 male athletes who represent Turkey on the International area and another 25 male volunteers who form the control group from the participants of the study. The sole pressure measurement of the participants was performed through the use of EMED-SF (Novel H, Munich, Germany) plantar pressure analysis system (pedobarographic analysis).  In the study, significant differences were found in heel medial, heel lateral, foot middle, 2nd, 3rd and 4th metatars heads and left foot 3rd, 4th, 5th finger in the contact area values of the right and left foot averages. Besides, significant differences were found in heel medial, middle part of feet, 2nd and 3rd metatars heads and 2nd, 3rd, 4th and 5th fingers in maximal force values. Athletes have pressed on sole of the feet more as a result of long-term training and as a consequence this pressure caused a change of the soles contact area and maximal strength. Also it can be said that they have used forefront part of soles more actively during running and walking.   Keywords: runner foot sole, contact area, middle distance, pedobarographic.

To the student of comparative political theory, few things are more fascinating than the contrast not only between different ages but also between different countries in one and the same age. The greatest advances in the collective thinking of Western humanity have been made coöperatively by men of every nation; and in every age all unite to give to that age its own distinctive character; yet each people contributes something of its own national genius to the spirit of the age. He, then, who would understand a country and the pattern of its people's thinking does well to inquire in what way it has deviated from the thinking of other nations in particular epochs.Whoever looks at early nineteenth-century America must be struck by its aloofness from many of the main currents of Western thinking. In the great Revolution of the eighteenth century, it had not been thus. The Lockean and Blackstonean tradition of the right of Englishmen to protect their property through representative organs; Rousseau's concept of equal natural rights of every individual and the right of the sovereign people in convention to reconstitute society according to its general will; Montesquieu's advocacy of checks and balances as safeguards of liberty; Quesnay's physiocratic cult of land as the natural source of wealth and power; Adam Smith's analysis of the relationship between national policy and private commerce; deism in religion; and associationism in psychology—these were among the many trends in the Age of Reason that came to a focus in the revolt of the thirteen colonies and the establishment of the United States.

AbstractPoor quantity of zooplankton was recorded in a Danube arm situated on the right side of the Danube River in Slovakia (river km 1857) in 2002 and 2003. All over the year the arm is significantly influenced by groundwater by reason of seepage. Because of low mean water temperature (12°C) and poorly developed macrovegetation in particular, the arm reminds gravel pit-like. The annual average of zooplankton biomass was low and ranged from 0.35 g m−3 (2002) to 1.28 g m−3 (2003), because of low crustacean abundance. Total cladoceran abundance was excessively low in both years and ranged from 3.5 N L−1 (2002) to 16.6 N L−1 (2003). Small species, Bosmina longirostris and Chydorus sphaericus were dominant. Only four adult Copepoda — Cyclops vicinus, Thermocyclops crassus, Eurytemora velox and Eudiaptomus gracilis — were recorded in quantitative samples of both years. In the zooplankton assemblage dominated rotifers (Synchaeta pectinata, Synchaeta oblonga, Polyarthra dolichoptera and Keratella cochlearis) which represented 78% and 67% of total abundance respectively. The total of 19 species of rotifers, 34 Cladocera species and 16 taxa of Copepoda were found.
