Viruses specifically infecting bacteria, or bacteriophages, are the most common biological entity in the biosphere. As such, they greatly influence bacteria, both in terms of enhancing their virulence and in terms of killing them. Since the first identification of bacteriophages in the beginning of the 20th century, researchers have been fascinated by these microorganisms and their ability to eradicate bacteria. In this review, we will cover the history of thePropionibacterium acnesbacteriophage research and point out how bacteriophage research has been an important part of the research onP. acnesitself. We will further discuss recent findings from phage genome sequencing and the identification of phage sequence signatures in clustered regularly interspaced short palindromic repeats (CRISPRs). Finally, the potential to useP. acnesbacteriophages as a therapeutic strategy to combatP. acnes-associated diseases will be discussed.

Bandung experienced a rapid urban development after 1918, when the city was prepared to be the new Dutch East Indies’ capital city, replacing Batavia. In the era of economic liberalization, Bandung also became one of the tourist destinations that has promoted by the businessmen. This paper is a study on how mass tourism as the new urban culture in the beginning of 20th century had a contribution to urban planning in Bandung. The timeline was after the establishment of train as a modern transportation in Bandung (1884) until the end of the Dutch Colonialism in Dutch East Indies (1942). Through the Georg Simmel's theory of sociology and the city, I tried to analyze the the tourism activity and its relations to the 20th century urban architecture in Bandung, West Java. I use the method that was introduced by Iain Borden and friends in The Unknown City to understand tourism and urban history of Bandung through the spatial practice, city representation and experiences.

The objective of the paper is to present Russian anniversaries that commemorate important historical events as phenomena with a dual, rhetorical and ironic character. Rhetoric and irony are used with reference to individuals as well as imagined communities, such as nations. The memory of some historical events, or the lack of such memory, as well as the manners of referring to these events or ignoring them, result in the transformation of what community members think about themselves and their entanglement in common existence and fate. Therefore, changes of remembrance and oblivion, recollection or forgetting can integrate or disintegrate, intensifying the pride or shame of one’s national identity, which eventually results in satisfaction or frustration, and sometimes in a sense of superiority or inferiority. Pride and satisfaction are produced by rhetoric, while shame and frustration – by irony. Sometimes rhetorical-ironic playing with the past assumes particular significance, becoming an exceptionally important factor in social and political life. This phenomenon strongly intensified in Russia in the beginning of the 20th century, becoming a veritable ‘anniver- sary-mania’, and in 2012, which President of the Russian Federation, Dmitry Medvedev, de- clared the Year of Russian History. The periods analyzed in the paper are around one hundred years apart. Russian society has totally changed over this period, mainly as a result of the revolution, two world wars and several decades of communist rule. In 1990, the Russian Federation was established, a state with an authoritarian-democratic hybrid of a political system. Despite these transformations, modern Russians repeat numerous set behavioral patterns from the beginning of the 20th century. These patterns are used by the advocates of affirmative as well as critical approaches to the history of Russia and the current social and political situation in the country.

To successfully interact with the environment, goal-oriented movements made by human limbs must be guided by instructions from the brain. Loss of the ability to program purposeful skilled movements, in the absence of any motor, sensory, or cognitive deficit that could fully account for this disability, is called apraxia. Several types of apraxia were described by Hugo Liepmann in the beginning of the 20th century: ideomotor apraxia, where patients make spatial movement and postural errors as well as temporal errors, limb-kinetic apraxia, where patients are unable to perform precise independend and coordinated finger movements and ideational apraxia, where patients fail to correctly sequence a series of action. More recently, three other types of apraxia have been described: conceptual apraxia, where patients have a loss of mechanical knowledge; dissociation apraxia, where patients are impaired at performing a skilled act in response to stimuli in one modality but can perform normally when the stimulus is given in another modality; and conduction apraxia, where patients are impaired at action imitation. This chapter, using an historical approach, reviews the signs associated with each of these forms of apraxia, as well as their pathophysiology.

This paper provides an overview on the history of the earliest applications of psychological practices in the two main mental institutions linked to the Assistance for Psychopaths in Rio de Janeiro, Brazil, in the beginning of the 20th Century. This encompassed a range of clinical practices that employed psychological techniques and tools thought as having a curative effect on the causes or symptoms of mental illness. Mental hygiene doctors used those techniques as well, with the biopolitical goal of averting illness and any consequent risk and social danger. The techniques are analyzed in their relation to the modernization project of Brazilian nation and to the problem of what was then understood as its “degenerated population”. The main objective of the paper is to investigate the role of Psychology in Brazil in the early 20th Century. The results appoint an effective interrelation between the raise of scientific legitimacy of Psychological knowledge and technology and the integration of Psychiatry within different nation's modernization projects.

Stereotactic neurosurgery has a rich history, beginning with the first stereotactic frame described by Horsley and Clarke in 1908. It is now widely used for delivery of radiation, surgical targeting of electrodes, and resection to treat tumors, epilepsy, vascular malformations, and pain syndromes. These treatments are now available due to the pioneering efforts of neurosurgeons and scientists in the beginning of the 20th century. Their efforts focused on the development of stereotactic instruments for accurate lesion targeting. In this paper, the authors review the history of the stereotactic apparatus in the early 20th century, with a focus on the fascinating people key to its development.

The study analyses István Szilágyi’s widely known novel Kő hull apadó kútba («A Stone Drops in a Dwindling Well») from the viewpont of fatefulness and falling into sin. The novel is an outstanding work in the 20th century hungarian literature, written by István Szilágyi who lives in the present Romania, Transylvania. The main character, Ilka Szendy faces with ethical dilemmas which can be examined from newer trends of cultural studies such as xenology. This study focuses on the following questions: how does the social system and compunction distort the personality? How does Ilka Szendy become a foreigner in the milieu in which she grown up? What kind of poetical pecularities, motifs, time and place usage represents the girl’s fate in the 20th century by the author? In the beginning of the study I explain the process how the literary historians realised the significance of this novel. This is an important issue because the history of hungarian literature and the history of hungarian literature across Hungary’s border developed differently in the 20th century – different experiences and poetical pecularities can be found in a novel. There are three different reading and canonizing strategies which outlined from the criticisms and studies: in the case of the first one, the emphasize was on the novel’s social aspects. The second one focused on the poetical aspect and structure. In the 2000s occurred the newest strategy which analyses the novel from the viewpoint of cultural studies. In this study I apply this third strategy. With the help of close reading I try to attempt connecting the own body’s alienation and the multiplication of the main character’s (Ilka Szendy) personality with the traumas that she experienced at her young age. Several experiences preceded the fall into sin (murdering), but the narrator tells them only later in the novel. As a reader we can explore the most effectively the fall into sin and the fulfillment of destiny through the context of Ilka Szendy’s experiences, deeds, thoughts, motifs, metaphors and the secrets that lead us into the family’s past. In the end of the study I connect Ilka Szendy’s destiny with her family’s past. The girl died beceause she rode for the fall. She knew that she could never be relesead from her guilt, she could receive absolution only by death.

Abstract As the main religion of Finland, but also of entire Scandinavia, Lutheranism has a centuries-long history. Until 1809 Finland formed the eastern part of the Swedish Kingdom, from 1809 to 1917 it was a Grand Duchy within the Russian Empire, and in 1917 Finland gained independence. In the 1520s the Lutheran Reformation reached the Swedish realm and gradually Lutheranism was made the state religion in Sweden. In the 19th century the Emperor in Russia recognized the official Lutheran confession and the status of the Lutheran Church as a state church in Finland. In the 20th century Lutheran church leaders preferred to use the concept people’s church. The Lutheran Church is still the majority church. In the beginning of 2015, some 74 percent of all Finns were members of the Evangelical Lutheran Church of Finland. In this issue of Perichoresis, Finnish historians interested in the role of church and Christian faith in society look at the religious history of Finland and Scandinavia. The articles are mainly organized in chronological order, starting from the early modern period and covering several centuries until the late 20th century and the building of the welfare state in Finland. This introductory article gives a brief overview of state-church relations in Finland and presents the overall theme of this issue focusing on Finnish Lutheranism. Our studies suggest that 16th and early 17th century Finland may not have been quite so devoutly Lutheran as is commonly claimed, and that late 20th century Finland may have been more Lutheran than is commonly realized.
