The results of calculation and theoretical investigation for the creation of a powerful (≈600 MW) pulsed MHD generator on the combustion products from solid (powder) plasma-forming fuel “Start-2” of a new generation are presented. The scheme, methods, results of calculations, and optimization of characteristics of the pulsed MHD generator with the self-excited resistive “iron-free” magnetic system are described. The local, integral, and specific energy and mass-dimensional characteristics are determined. The obtained characteristics are 1.5-2 times higher than those of the first generation MHD generator.

The creation of The American Phytopathological Society (APS) in 1908 was a response to the developing professionalism in the biological and agricultural sciences in the United States between 1880 and 1920. During this period, a new generation of plant pathologists emerged in the United States Department of Agriculture, agricultural colleges, and state agricultural experiment stations with a methodological and theoretical framework to determine the cause and nature of disease and make control recommendations based on experimental evidence. These plant pathologists, in turn, became eager to establish a professional identity, for some an identity separate from traditional botany and mycology. For these scientists, the goal would be facilitated by establishing a new society for plant pathologists. The story of the creation of APS is best understood within the nature of the ensuing debates over identity and the merits of forming a new society among its first generation of scientists.

Alif means the first, saying the Supreme Life and is Sturdy and has the element of fire and Alif is formed from Ulfah (closeness) ta'lif (formation). With this letter Allah mementa'lif (unite) His creation with the foundation of monotheism and ma'rifah belief in appreciation of faith and monotheism. Therefore, Alif opens certain meanings and definitions of shapes and colors that are in other letters. Then be Alif as "Kiswah" (clothes) for different messages. That is a will. "IQRO" is a revelation that was first passed down to the Prophet Muhammad. Saw. Read it, which starts with the letter Alif and ends with the letter Alif. The creation of a poem is influenced by the environment and the self-reflection of a poet where according to the poet's origin, in comparing in particular Alif's poetry from the two poets. The object of this research is the poetry of Zikir by D. Zawawi Imron and Sajak Alif by Ahmadun Yosi Herfanda. This study uses a comparative method and sociology of literature. Through a comparative study of literature between the poetry of Zikir D. Zawawi Imron and Sajak Alif Ahmadun Yosi Herfanda, it is hoped that the public can know the meaning of Alif according to the poet's view. With this research, the Indonesian people can accept different views on the meaning of Alif in accordance with their respective understanding without having to look for what is right and wrong. The purpose in Alif is like a life, in the form of letters like a body, a tree that is cut to the root, from the heart is split to the seeds, then from the seeds are split so that nothing is the essence of life. So, it is clear that Alif is the most important and Supreme letter. Talking about the meaning of Alif as the first letter revealed on earth. After the letter Alif was revealed, 28 other Hijaiyah letters were born. The letter Alif is made the beginning of His book and the opening letter. Other letters are from Alif and appear on him.

The purpose of this review is to evaluate progress inmolecular epidemiology over the past 24 years in canceretiology and prevention to draw lessons for futureresearch incorporating the new generation of biomarkers.Molecular epidemiology was introduced inthe study of cancer in the early 1980s, with theexpectation that it would help overcome some majorlimitations of epidemiology and facilitate cancerprevention. The expectation was that biomarkerswould improve exposure assessment, document earlychanges preceding disease, and identify subgroupsin the population with greater susceptibility to cancer,thereby increasing the ability of epidemiologic studiesto identify causes and elucidate mechanisms incarcinogenesis. The first generation of biomarkers hasindeed contributed to our understanding of riskandsusceptibility related largely to genotoxic carcinogens.Consequently, interventions and policy changes havebeen mounted to reduce riskfrom several importantenvironmental carcinogens. Several new and promisingbiomarkers are now becoming available for epidemiologicstudies, thanks to the development of highthroughputtechnologies and theoretical advances inbiology. These include toxicogenomics, alterations ingene methylation and gene expression, proteomics, andmetabonomics, which allow large-scale studies, includingdiscovery-oriented as well as hypothesis-testinginvestigations. However, most of these newer biomarkershave not been adequately validated, and theirrole in the causal paradigm is not clear. There is a needfor their systematic validation using principles andcriteria established over the past several decades inmolecular cancer epidemiology.

In attempting to characterize Second Temple legends of the Hasmoneans, the concluding chapter identifies several distinct genres: fragments from Aramaic chronicles, priestly temple legends, Pharisaic legends, and theodicean legends explaining the fall of the Hasmonean dynasty. The chapter then examines, by generation, how Josephus on the one hand, and the rabbis on the other, reworked these embedded stories. The Josephan treatment aimed to reduce the hostility of the early traditions toward the Hasmoneans by imposing a contrasting accusatory framework that blames the Pharisees and justifies the Hasmonean ruler. The rabbinic treatment of the last three generations exemplifies the processes of rabbinization and the creation of archetypal figures. With respect to the first generation, the deliberate erasure of Judas Maccabeus’s name from the tradition of Nicanor’s defeat indicates that they chose to celebrate the Hasmonean victory but concealed its protagonists, the Maccabees, simply because no way was found to bring them into the rabbinic camp.

The chapter examines the emergence of literature from coteries and domestic routine. It describes how male poetic circles, held together by friendship and common intellectual interests, produced the interconnected institutions of literature necessary to literature. While early in the century, women writers mostly worked privately, they eventually moved into more public venues such as the salon. An interest in subjectivity, the self, and friendship networks, which were also reading communities, fostered the creation of a performative and reflective self that gave rise to literary heroes to satisfy the new interests and demands of writers and readers.

AbstractThis article explores the practices of private communication of Muslims at the eclipse of the Russian empire. The correspondence of a young Kazan mullah with his family and friends lays the ground for an analysis of subjectivity at the intersection of literary models and personal experience. In personal writings, individuals selected from a repertoire of available tools for self-fashioning, be that the usage of notebooks, the Russian or Muslim calendar, or peculiarities of situational language use. Letters carried the emotions of their writers as well as evoking emotions in their readers. While still having access to the Persianate models of the self, practiced by previous generations of Tatar students in Bukhara, the new generation prioritized another type of scholarly persona, based on the mastery of Arabic, the study of the Qur’an and the hadith, as well as social activism.

Abstract This study explores the depictions of landscapes and emotions in the ninth-century hagiographies associated with Liudger: the three vitae Liudgeri and Liudger’s own vita Gregorii. The Frisian missionary founded the monastery of Werden, situated near the Frankish-Saxon frontier. It will be argued that previous historiography on early medieval frontiers has predominantly focused on the military nature of frontiers. Here, more cultural or symbolic natures of the Frankish-Saxon frontier will be discussed. The hagiographical narratives will be examined in conjunction with the notion of a frontier as a ‘third space’. The vitae Liudgeri shaped a discourse that legitimated Liudger’s translation to Werden. This resulted in the creation of a new place of Christian worship in the competitive landscape of post-conquest Saxony, as part of the Christianization of the region. Monasteries like Werden were the places where new missionaries were educated who would continue this Christianization. Exemplary emotional behaviour of the saints, narrated in hagiographies, could help instruct this new generation. Altfrid and Liudger tried to dissuade emotions of anger, indicated by ira or furor, with their hagiographical narratives. These two perspectives offer a glimpse into the attempts of a local monastery to stand out in the Frankish-Saxon frontier.

Numbers describes the building of an Israelite collective in the wilderness. A fledgling people struggle mightily to form themselves into a unity but are overcome by their own complaints, desires for a past they leave behind in Egypt and doubts of their ability to conquer the promised land. Several stories highlight the dramatic pressures both internal (how they saw themselves) and external (how they imagined others saw them) that influence the successes and failures of a unified Israel. Yet the self-critique embedded in the tale of the journey leads a new generation to replace dissatisfaction and dissent with a shared determination. A tale of struggles overcome gives the children of Israel a chance to reach for a different future, imagined but not yet fulfilled.
