Francis I. Proctor, MD and his wife Elizabeth C. Proctor: Their lives and legacy
No full text The Francis I. Proctor Foundation for Research in Ophthalmology is internationally recognized for its research in the fields of ocular inflammatory and infectious diseases. Although the name of one of its founders, Francis I. Proctor, MD (1864–1936) is memorialized, the legacy of his wife, Elizabeth C. Proctor (1882–1975) is not as well known. They were both full partners in this endeavor. Francis, a successful and wealthy ophthalmologist, retired to Santa Fe, New Mexico. After their marriage, they became interested in the problem of blinding trachoma, then an endemic problem on the Native American Indian reservations. The couple selected Phillips Thygeson, MD (1903–2002), a young ophthalmologist with an interest in infectious diseases, as their lead investigator. Using their own funds, the Proctors paid for Thygeson and themselves to study trachoma in Egypt, and then establish a trachoma research laboratory in Arizona where the causative agent of trachoma was identified. Not only did the Proctors fund these studies, they also studied bacteriology so they could help in the laboratory themselves. After Francis’ death, Elizabeth endowed the Foundation in 1947 and continued to support it. She also established the Proctor Medal for The Association for Research in Vision and Ophthalmology. </jats:p
Mary Proctor: An astronomical popularizer in the shadows
No full textThe popularizer of astronomy Mary Proctor was well known in her days but has been little remembered since. A prominent lecturer and author, Proctor was trained in the craft of science writing by her father, Richard Proctor. She ‘held the very first place in the profession as a woman’ and promoted the role of women in science throughout her career. Her life illuminates many themes. Mary Proctor spanned the period between entrepreneurial science popularizers and professional science communicators. I suggest that one of her most important legacies is as an early pioneer of the practices of science journalism in the early twentieth century when the relations between science and society were in flux. Yet her legacy has been largely overlooked. A study of Proctor's life reveals multiple interests, diverse opportunities and the way that people are differently remembered
The synthesis of monodisperse alkanes with long chains
No full textThis thesis discusses reasons for the interest in monodisperse long chain alkanes and describes attempts, past and present, to synthesise such molecules. Chapter 1 discusses why the synthesis of such molecules are important and the objectives of this project. Chapter 2 reviews the methods previous groups have devised to prepare pure samples of long chain alkanes. In particular, work carried out by Whiting et al. at Bristol, whose scheme formed the basis of the early work in Durham. Chapter 3 describes the work in Durham and improvements which were made to Whiting's method, allowing the synthesis of longer chain lengths and greater quantities of materials to be achieved. Chapter 4 provides a summary of the practical work carried out by the author. Chapter 5 gives experimental details of the work described in Chapter 4

Prodorsal shield: entire, covering most of prodorsum, length and greatest width subequal, posterior angles roughly rectangular or rounded, not extending to lateral margins of propodosoma, lateral margins without incision around scapular setae. Complement of idiosomal setae complete for Analgoidea except for vertical setae <i>vi</i>. Humeral shields well developed, fused with epimerites III and incorporating bases of setae <i>cp</i> and <i>c3</i>. Complement of leg setae complete for Proctophyllodidae. Epimerites I fused into a Y. Genua and femora of all legs strongly thickened, over twice as thick as corresponding tarsi. Articulation between genu and femur in all legs immovable. Setae <i>wa</i> of tarsi I, II anterior to corresponding setae <i>ra</i> and <i>la</i>. Solenidion σ <i>1</i> of genu I longer than solenidion ω <i>3</i> on tarsus I.</p> <p> Male. Opisthosoma wide, parallel-sided. Opisthosomal lobes short and wide, posterior margin of lobes with extensions bearing setae <i>f2, h2, h3</i>. Terminal lamellae absent. Terminal cleft present, small. Setae <i>f2</i> lanceolate, posterior to level of setae <i>ps2</i>. Setae <i>ps1</i> lanceolate. Setae <i>h3</i> large, situated marginally, setiform, comparable in size to setae <i>h2.</i> Genital apparatus at level of trochanters IV or posterior to it. Aedeagus short, not much longer than genital arch. Genital papillae close to genital arch. Genital shield(s) absent. Adanal shields represented by small plates at bases of <i>ps3</i>. Paragenital apodemes absent. Setae <i>g</i> and <i>ps3</i> distant from each other, arranged in narrow trapezium. Adanal suckers large, cylindrical (barrel-like). Corolla indented. Legs III, IV subequal in size, not hypertrophied. Solenidion σ <i>1</i> on genu III approximately at midlevel of segment, longer than segment. Tarsus IV straight, attenuate apically. Setae <i>d, e</i> button-like.</p> <p> Female. Females noticeably larger than males. Lobar region clearly demarcated from remaining part of opisthosoma by lateral concavities, shorter than ¼ of hysterosoma. Opisthosomal lobes well developed, with terminal appendages. Terminal cleft V-shaped with rounded bottom. Hysteronotal shield entire, not separated into anterior and lobar parts. Setae <i>h2</i> macrosetae, setae <i>h3</i> setiform. Setae <i>ps1</i> lanceolate. Epigynum roughly semicircular, with short lateral extensions, tips of epigynum not extending to level of genital papillae.</p> <p> Differential diagnosis. Among 17 previously known genera of Proctophyllodinae (Gaud & Atyeo 1996; Hernandes <i>et al</i>. 2007; Mironov 2009), the genus <i>Atelophyllodes</i> gen. n. most resembles <i>Ptyctophyllodes</i> Atyeo, 1967, associated with Trogonidae (Trogoniformes) (Atyeo 1967), in that males in both genera have short and wide opisthosomal lobes lacking terminal lamellae on their posterior margins. <i>Atelophyllodes</i> differs from <i>Ptyctophyllodes</i> and also from other known proctophyllodine genera by the following combination features: in both sexes, epimerites I are fused into a Y; genu and femur of legs I, II are over 2 times thicker than corresponding tarsi; in males, lamellar structure on the posterior opisthosoma are completely absent, paragenital apodemes are absent, and anal suckers are large and cylindrical; in females, the hysteronotal shield is not separated into anterior and lobar parts by unsclerotized integument. In both sexes of <i>Ptyctophyllodes</i>, epimerites I are fused in a narrow U, tarsi of legs I, II are approximately subequal in thickness to corresponding genu and femur; in males, paragenital apodemes formed by elongated epimerites IVa are present, and anal suckers are disc-like; in females, the hysteronotal shield is clearly separated into anterior and lobar parts. It is necessary to add that in <i>Ptyctophyllodes</i>, lamellar structures on opisthosoma are actually present (at least in the form of male which may be referred to as heteromorph), but these lamellae are situated on the dorsal surface of opisthosoma and are directed anteriorly.</p> <p> Remarks. The fusion of epimerites I into a Y (a rare character state in Proctophyllodinae) is also present in <i>Anorthalloptes</i> Atyeo and Gaud, 1976 and <i>Mimicalges</i> Atyeo and Gaud, 1971, but males of these genera have quite differently shaped opisthosomas (elongate and attenuate to terminus), and strongly hypertrophied legs IV (Atyeo & Gaud 1971b, 1976).</p> <p> Etymology. Contraction of <i>atel</i> ē <i>s</i> (imperfect, G.) and the generic name <i>Proctophyllodes</i> to refer to the absence of terminal lamellae in males; gender masculine.</p>Published as part of <i>Mironov, Sergey V. & Proctor, Heather C., 2009, Atelophyllodes gen. n., a new feather mite genus of the family Proctophyllodidae (Astigmata: Analgoidea) from lyrebirds (Passeriformes: Menuridae), pp. 51-61 in Zootaxa 2326</i> on pages 52-53, DOI: <a href="http://zenodo.org/record/192069">10.5281/zenodo.192069</a>

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
