1. The reversible equilibrium between the mitochondrial ATPase (f₁) and its naturally occurring inhibitor in Mg-ATP submitochondrial particles has been studied under different conditions. 2. High ionic strength favours dissociation of the ATPase inhibitor as tested by ATPase and ATP-driven transhydrogenase activities. 3. Dissociation of the ATPase inhibitor results in an increased maximal velocity of the ATPase activity measured in the presence of uncoupler and an increased affinity for adenine nucleotides, in particular for ATP. 4. Association of the ATPase inhibitor with inhibitor-depleted Mg-ATP particles causes a slowing of the initial rate of succinate oxidation. 5. The antibiotic aurovertin stimulates the ATPase activity of Mg-ATP particles preinculbated in the presence of a supply of oxidative energy. Bound aurovertin impedes the association of inhibitor-deficient particles with ATPase inhibitor. 6. The fluorescence of aurovertin bound to inhibitor-containing particles is much less than that of aurovertin bound to inhibitor-depleted particles. 7. The oligomycin-sensitivity-conferring protein, added either alone or in the presence or absence of membranous components of the ATPase complex, has little or no effect on the fluorescence of the f₁-aurovertin complex. 8. It is suggested that the ATPase inhibitor brings f₁ in a conformation denoted *f₁ that binds aurovertin with a low quantum yield, a decreased affinity and an increased binding capacity. © 1974.

Development of history of education as a school and study course in Slovenia through the reception of J. f. Herbart

引用

PAEDAGOGICA HISTORICA 2022年第6期58卷 821-834页

作者： Protner, Edvard Univ Maribor Maribor Slovenia

This article reconstructs the phases of development of the history of education as a school subject and subject within the framework of the education of teachers at teacher training schools from 1869 onwards, and the presence of these contents at teacher training academies after 1960 and faculties of education after 1986. At the same time, it examines the position and the presence of this subject in the course of educational studies at the faculty of Arts in Ljubljana during the interwar period and during the period following the Second World War until Slovenia's gaining of independence. Also presented is the situation in this field in three study programmes of educational science in Slovenia. On this subject, the article will look at changes in content focus. Based on the analysis of records on J. f. Herbart in textbooks on the history of education and educational articles, an attempt is made to recognise the development of interpretational patterns and to focus on his educational ideas relating to current trends. Although J. f. Herbart may be regarded as one of the key educational classics, authors in Slovenia have seldom read Herbart in the original. for more than a century, the records relating to him have been repeating controversial stereotypes, and only in the recent period has there been a positive shift in this field.

1. 1. f₁ and OSCP, soluble coupling factors isolated from beef-heart mitochondria, form a complex. 2. 2. The binding between f₁ and OSCP is weakened by (NH₄)₂SO₄, but not enough to allow complete separation of f₁ and OSCP in a linear sucrose gradient. Complete separation is achieved when both (NH₄)₂SO₄ and deoxycholate are present. 3. 3. f₁·X, a coupling factor also isolated from beef-heart mitochondria, can be separated in f₁ and OSCP activities in the presence of (NH₄)₂SO₄ and deoxycholate by centrifugation in a linear sucrose gradient or by gel filtration on a Sephadex G-100 column. 4. 4. f₁·X preparations of low specific activity contain a contaminating protein. This protein can be dissociated from the complex by (NH₄)₂SO₄. f₁·X preparations with a high specific activity are virtually free of this contaminating protein. 5. 5. f₁·X preparations contain approximately 30% free f₁. 6. 6. Analytical gel electrophoresis of f₁·X, f₁ and OSCP in the presence of sodium dodecyl sulphate indicates that apart from f₁ and OSCP no other components are present in pure f₁·X. © 1972.

TRACING THE JAMESIAN INfLUENCE ON SELECTED NOVELS Of MANNERS BY JOHN GALSWORTHY, NATSUME SOSEKI, AND f. SCOTT fITZGERALD

TRACING THE JAMESIAN INFLUENCE ON SELECTED NOVELS OF MANNERS...

引用

作者： MURAT CAGLIYAN Middle East Technical University

学位级别：博士

This dissertation attempts to trace the Jamesian influence on selected novels of manners by John Galsworthy, Natsume Soseki, and f. Scott fitzgerald, who are three leading early-twentieth-century novelists of manners from England, Japan, and America respectively. In view of the recent inclination to accentuate the coexistence of social and psychological dimensions in the novel of manners, this study maintains that the influential version of this form implemented by Henry James in the literary scene anticipates the later- published individuation theory of Carl Gustav Jung who is known to have been influenced by Henry's equally eminent psychologist and philosopher brother, William James. By analysing the selected novels with regard to both the Jamesian novel of manners and Jungian individuation, this dissertation aims to lay bare Henry James's extensive and transformative influence within the novel of manners tradition not only in terms of foregrounding the psychological dimension already inherent in this form, but also with respect to turning its interest towards the unconscious. Within this framework, Henry James's The American, John Galsworthy's Jocelyn, Natsume Soseki's Kokoro, and f. Scott fitzgerald's Tender is the Night are examined.

Some properties of selectively star-ccc spaces

引用

TOPOLOGY AND ITS APPLICATIONS 2025年 367卷

作者： Sun, Yuan Beijing Univ Civil Engn & Architecture Sch Sci Beijing 102616 Peoples R China

In 2013 [2], Aurichi introduced a topological property named selectively ccc that can be viewed as a selective version of the countable chain condition (CCC). Later, Bal and Ko & ccaron;inac in [3] extended Aurichi's work and defined the star version of the selectively ccc property called selectively k-star-ccc. The aim of this paper is twofold. firstly, we establish connections between the selectively k-star-ccc properties, the chain conditions and other star-Lindel & ouml;f properties. Secondly, some examples are presented to solve questions raised by Xuan and Song in [12]. (c) 2025 Elsevier B.V.

The constitutional faith of William f. Buckley, Jr

The constitutional faith of William F. Buckley, Jr

引用

作者： Lang,Joseph B Southern Illinois University

学位级别：Doctor

William f. Buckley is generally regarded as one of the founders of modern conservatism. Despite his recognition as one of the leaders of modern conservative thought,he has received scant attention from academics in any particular discipline. The paucity of literature on Buckley suggests that his contribution to American constitutionalism has not been fully appreciated. To date there has been no comprehensive analysis of Buckley's nonfiction writings for the purpose of revealing the foundations of his constitutionalism. This dissertation analyzes Buckley's nonfiction writings in the context of classical,medieval,and modern philosophy for the purpose of determining the precise nature of his understanding of constitutionalism. There is a tendency,particularly in modern times,to view constitutionalism as a set of judicial glosses on the meaning and substance of the written Constitution. This understanding of constitutionalism has resulted in the aggrandizement of the United States Supreme Court among American institutions. Against this view,Buckley argues that a proper understanding of constitutionalism rests on the foundations of religion,tradition,and moral conventions. This of course suggests that there are fundamental underlying constitutional experiences which may reflect more accurately the reality of the written document. These underlying experiences reveal a normative reality consisting of a political order's values and traditions,which in turn legitimate the substance of the written political instrument. Buckley's writings reveal a conception of constitutionalism which must remain normative,grounded in human experience,and tethered to God. Constitutionalism itself must be understood to be animated by the customs,traditions,and values of the political order,the very real experiences of individual citizens. It is argued in this paper that Buckley's antipathy toward liberalism stems from his perception of the tendency of liberalism to reject tradition and many of

1. The naturally occurring mitochondrial ATPase inhibitor inhibits the mitochondrial ATPase (f₁) non-competitively. 2. The interaction between inhibitor and inhibitor-depleted f₁ or submitochondrial particles is diminished when the ratio of ATP/ADP is low or when energy is generated by substrate oxidation. 3. The dissociation of the inhibitor from coupled Mg-ATP particles is promoted when substrates are being oxidized. This results in the appearance of a large uncoupler-stimulated ATPase activity. Activation of the uncoupler-stimulated ATPase activity is also achieved by incubation of the particles with ADP. 4. The ATPase activity of Mg-ATP particles is determined by the turnover capacity of f₁. When endogenous inhibitor is removed, energy dissipation becomes the rate-limiting step. This energy dissipation can be activated by an uncoupler. 5. Evidence is presented for the existence of a non-inhibited intermediate f₁-inhibitor complex. © 1973.

Modified Checklist for Autism in Toddlers Revised (MCHAT-R/f) in an Urban Metropolitan Sample of Young Children in Turkey

引用

JOURNAL Of AUTISM AND DEVELOPMENTAL DISORDERS 2020年第9期50卷 3312-3319页

作者： Oner, Ozgur Munir, Kerim M. Bahcesehir Univ Dept Child Psychiat Sch Med Istanbul Turkey Harvard Med Sch Boston Childrens Hosp Boston MA 02115 USA

The study assessed the feasibility of using a Turkish-version of the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R/f) as a screening tool for an urban low risk population of young children. M-CHAT-R/f was completed for 6712 children between ages 16 and 36 months living in Istanbul, Turkey. Autism Diagnostic Observation Schedule-2 was served as the main measure for diagnosis. M-CHAT-R/f screen was positive for 9.8% of children. At follow up interview, 39.7% of initial screen-positive children met criteria for ASD. The study identified 57 (1 in 117) children with ASD (0.8%;95% CI 0.063-1.05%). M-CHAT-R/f performed comparably in Turkey as in United States. Implications of the study for future universal screening for autism in Turkey is also discussed.
