This paper presents that in the Russian Revolution 1) socialist and alternative democratic conceptions between Marx and Lenin are very different, 2) the process and cause of failure of realizing Lenin's democratic alternative conception, 3) the interactive expansion process of the party and the state, 4) the failing process of socialist original accumulation, collectivization, and constructing planned economy. This shows that Russia could not help fail to transit to socialist society due to the combination of wrong conceptions and that new revolution and construction should combine right socialist and democratic conceptions.

In order to determine possible relationships between the renin-angiotensin system and nephron heterogeneity, we compared the response of renin release and the angiotensin-converting enzyme (ACE) activity from different areas of the rat kidney. We used the renal cortical slices from the capsular surface to the juxtamedullary junction. Slices from outer one-third of the cortex were designated as outer cortical slices (OC), middle one-third as midcortical slices (MC), and inner one-third as inner cortical slices (IC). The renal renin content markedly decreased from OC and MC to IC. The basal lenin release was higher in OC than in MC or IC. On the contrary the percent change of renin release in response to L-isoproterenol was significantly higher in MC than in OC or IC. By TMB-8, the renin release in MC by $231{\pm}21%$ was higher than OC by $171{\pm}19%$ or IC by $$162{\pm}19. Angiotensin II suppressed renin release in OC and MC by $68{\pm}2,\;71{\pm}4%$ respectively, but only $40{\pm}7%$ in IC. The ACE activity was higher in IC than in OC, MC, medulla and papilla. The present data indicate that renin content and basal lenin release gradulally decreased from outer (OC) to inner (IC) cortex. The renin release in response to beta-adrenergic agonist, L-isoproterenol and intracellular calcium antagonist, TMB-8 were higher in MC than in OC and IC, but angiotensin II suppressed renin release less in IC than in OC and MC. It is suggested that juxtaglomerular cells of outer, mid-and inner cortices show a difference in renin release response to the stimuli.

This paper aims to research the historical development of the archival systems in the Soviet Union from 1917 to the 1920's. The Russian revolution was the turning point not only for the political and social changes but for the archival administration in Russia, as it provided the new Soviet regime with the chances to reorganize the archival institutions under Bolshevik rule. However, we must not forget the fact that the Russian Archival Workers' Union had taken part in the organization of the archival systems together with the Bolshevik revolutionaries. The Soviet government intended to transform the decentralized and poorly organized archival systems in the prerevolutionary years into the centralized and bureaucratized ones. In this meaning, the decree signed be V. I. Lenin on 1 June 1918 was estimated as the real basis for the Soviet archival centralization. Lenin's archival decree of 1918 encompassed the entire national documentary legacy, which was gradually extended to all types and categories of manuscripts and archival records by successive legislation. The concept of state proprietorship of all documentary records was designated "Single State Archival Fond"(Edinyi Gosudarstvennyi arkhivnyi fond), which was renamed as "Archival Fond of the Russian Federation" after the collapse of the USSR. The independent state administrative agency, that is, "Main Administration of Archival Affairs"(Glavnoe upravlenie arkhivnym delom) was charged with the management of the entire "Single State Archival Fond". While the Soviet Union reorganized its archival systems in the twenties, the archival institutions became under the severe control of the government. For example, M. N. Pokrovskii, the well-known Marxist historian and the political leader, headed the organizational work of archives in the Soviet Union, which resulted in the exclusion of the prerevolutionary specialists from the archival field in the Soviet Union. However, the discussions over the concept of "the Archival Fond" by B. I. Anfilov helped to develop the archival theories in the USSR in the twenties. In conclusion, the Soviet Union, having emphasized the centralization of the archives, developed its archival systems from the early period, which were the basis of the systematic archival institutions in Russia.

The world's nuclear powered ships have been reviewed mainly based on development of the marine nuclear reactor and the present trends of nuclear warships and merchant ships in the world. In particular, emphasis was on the four nonmilitary nuclear ships, Russian Ice breaker Lenin, American Cargo-passenger ship Savannah, German Ore carrier Otto Hahn, and Japanese Cargo ship Mutsu. They are the only civilian nuclear ships which have entered service at the present time in the world. The nuclear fleets in United States, United Kingdom, Soviet, and France were described in view of historical development and the present stock of the nuclear ships. The present projects and the future trends for the nuclear merchant ships in the main shipbuilding countries have been also discussed. The nuclear fission and reactor were briefly discussed in the beginning of this article.

This manuscript work presents a comprehensive continuum model capable to investigate the effect of porosity on vibro-acoustic behaviour of functionally graded (FG) beams resting on an elastic foundation subjected to thermal and mechanical loadings. Effects of uniform temperature rise and edge compressive load on the sound radiation characteristics are studied in a comparative manner. The numerical analysis is carried out by combining finite element method with Rayleigh's integral. Detailed parametric studies are accomplished, and influences of power law index, porosity volume, porosity distribution and boundary conditions on the vibro-acoustic response characteristics are analyzed. It is found that the vibro-acoustic response under mechanical edge compression is entirely different compared to from that under the thermal load. Furthermore, nature of grading of porosity affects the sound radiation behaviour for both the loads. The proposed model can be used to obtain the suppression performance of vibration and noise FG porous beams under thermal and mechanical loads.

Acute and chronic effects of ethanol (EOH) administration on the cardiovascular and hormonal responses to repeated hemorrhage were investigated in conscious normotensive Wistar rats and spontaneously hypertensive rats (SHR). The chronic EOH treated group received 5% EOH (vol/vol) ad libitum in the drinking water far the first week,10% for the last 2 weeks, and 20% for the last 5 weeks from the age of 6 weeks. The EOH free group received tap water. Chronic EOH and EOH free groups were randomly subdivided into acute EOH infusion and control groups. Under ether anesthesia, catheters were inserted into the femoral vein and both femoral arteries. After rats regained consciousness and their blood pressure was stabilized, responses to quick hemorrhage (5 ml/kg BW) were tested. In the acute EOH infusion group, hemorrhage was induced 20 min after EOH infusion (1.0 g/kg BW), Baroreceptor reflex sensitivity was assessed by the ratio of changes in hen.1 rate and mean arterial pressure (${\Delta}HR/{\Delta}MAP$) immediately after the hemorrhage. Chronic EOH administration elevated MAP in Wistar rats. During acute EOH infusion, MAP do- creased and HR increased in all groups. In comparison to EOH free control rats, acute or chronic EOH treated rats showed a greater reduction in MAP and a smaller elevation in heart rate in response to a hemorrhage. The degree of MAP reduction was significantly greater in SHR than in Wistar rats. Both the acute and chronic EOH administration attenuated the baroreceptor reflex and retarded MAP recovery, again the trend being much more prominent in SHR. The increase in plasma vasopressin and lenin concentrations after hemorrhage were intensified by the chronic EOH administration. SHR showed a greater vasopressin response but a smaller lenin response than Wistar rats. These results indicate that the EOH treated rats, particularly SHB, are prone to shock by a hemorrhage, which may be partly attributed to an impaired baroreceptor reflex function.

The Russian revolution and the successive "art into production" atmosphere provided a unique model of a strict inter-relation between social process and innovative process in the taste. Influenced by CUBISM, RAYONISM and SUPREMATISM emerged in Russia around the time of Russian revolution and gave way to CONSTRUCTIVISM, based on Tatlin's theory, which played a vital role to combine art with social committment. One of the first question to be established after the revolution was the function of art within the new society. First, it should be propagandistic and empahsise the benefit of the new state. Secondly, art could take on an affirmatory role putting foward ideal views of the society as example to be disscussed and followed. Thirdly, the Constructivists' view, "Death to Art" was their slogan. Their view was that the artists' work in the new society was to be based on the material value and beauty in fuction as this alone could be consistent with the aesthetics of Marx and Lenin. It sould be pointed out that among the various applied arts, textiles and clothing design were considered one of the most important role in propaganda and in support of the new socialst ideas. Traditionl handicrafts provided a repository of popular images and folk art continued to assert an influence on the textiles and clothing design after the revolution. Constructivists, such as Stepanova and Popova, went to the factory as direct answer to the invitation for the art-industry rapport. Thematic or propagandistic designs were directly connected to the daily life and national transformation.

The change of plasma renin activity is one of the most important parameters explaining the pathological physiology of the hypertension. The relation between renal renin activity and plasma renin activity has not well been documented since last decades. In an attempt to clarify the relationship a series of experiments have been done in rats. The following results were observed. 1) Renal renin activity of clamped kidney increased after silver clipping and the increments were maintained until four to five weeks of operation. 2) Renal renin activity of the untouched contralateral kidney was vulnerable to be suppressed just after clamping, and the activity disappered almost below the limitation of the radioimmunoassay sensitivity up to four weeks. 3) Plasma lenin activity was changed by the renal renin activity, but the regression coefficient from the two kidney one clip Goldblatt hypertensive rats was different from the sham-operated, or age-matched control rats. 4) Plasma renin activity of all the groups tested has the exponential curve in terms of renal renin activity. These data suggest that the renal renin activity is important to control the plasma renin activity in certain experimental condition, especially in chronic status.

Alzheimer's disease severely compromises cognitive function. One of the mechanisms to explain the pathology of Alzheimer's disease has been the hypotheses of amyloid-pore/channel formation by complex $A{\beta}$-aggregates. Clinical studies suggested the moderate alcohol consumption can reduces probability developing neurodegenerative pathologies. A recent report explored the ability of ethanol to disrupt the generation of complex $A{\beta}$ in vitro and reduce the toxicity in two cell lines. Molecular dynamics simulations were applied to understand how ethanol blocks the aggregation of amyloid. On the other hand, the in silico modeling showed ethanol effect over the dynamics assembling for complex $A{\beta}$-aggregates mediated by break the hydrosaline bridges between Asp 23 and Lys 28, was are key element for amyloid dimerization. The amyloid pore/ channel hypothesis has been explored only in neuronal models, however recently experiments suggested the frog oocytes such an excellent model to explore the mechanism of the amyloid pore/channel hypothesis. So, the used of frog oocytes to explored the mechanism of amyloid aggregates is new, mainly for amyloid/pore hypothesis. Therefore, this experimental model is a powerful tool to explore the mechanism implicates in the Alzheimer's disease pathology and also suggests a model to prevent the Alzheimer's disease pathology.

To evaluate the acute and chronic effects of potassium on aldosterone response to different amounts of sodium intake, two series of experiments were conducted. In the first series of experiments, when the plasma K level was increased acutely by KCI infusion $(20\;{\mu}g/kg/min\;for\;20 min)$, plasma aldosterone concentration increased in both low Na and high Na groups. However, the aldosterone response to K infusion was significantly greater in the low Na than in the high Na groups. In the second series of experiments, rats fed a high K diet chronically showed a significantly higher plasma K level than those fed a low K diet. However, plasma Na level was maintained relatively constant independent of the Na intake. Both the plasma renin activity (PRA) and aldosterone levels were inversely related to the Na intake. There was a highly positive correlation between aldosterone level and PRA over a wide range of sodium intakes. However, the slope of the correlation line was distinctly steeper in the K-repleted than in the K-depleted rats. The above results indicate that the adrenotropic action of acute K load was augmented in the presence of high plasma renin levels. However, when plasna K level was elevated chronically by a high-K diet, aldosterone secretion was markedly stimulated, although the plasma lenin levels were suppressed.
