No full textIn a letter to Horace Kephart on April 30, 1919, J. D. Carpenter, secretary of the Lancaster Rifle Club, discusses a small collection of pistols he acquired from Mr. Sawyer. Since he received the Springfield rifle, Mr. Carpenter explains he will review the rifle’s description for Mr. Sawyer’s manuscript. He discusses his gun collection, including pistols, rifles, muskets, and carbines. He mentions the prospect of viewing an 1824 J. H. Halls Harpers Ferry Flintlock rifle, but had a misunderstanding with the owner

Mr. Harace Kephart,
Bryson City, I. fl>.
Dear Sir:-
Having read your articles on the 8ackwoods
rifle in Outing, I have been wondering if you could
tell me whether there are any book or books #$
describing firearms from 1800 on.
I have, nhas. w. Sawyers book treating on
the subjact from 1609 to iboo 'Firearms in American
History,
I have played the rifle game for more that
Si years, and I am also bugs on antique firearms, I
have collected some and ara stili collecting more, and
should like to get hold of some work or works desc/ribing
firearms from 1800 on, if you know of any and how^i
can secure them, I'should like to know,
I can assure you thft any information along
these lines that you can or will give rae, would be
very much appreciated, thanking you kindly in advance
I am.
Yours; truxy,,

Mutations in multidomain protein MEGF8 identify a Carpenter syndrome subtype associated with defective lateralization
No full textCarpenter syndrome is an autosomal-recessive multiple-congenital-malformation disorder characterized by multisuture craniosynostosis and polysyndactyly of the hands and feet; many other clinical features occur, and the most frequent include obesity, umbilical hernia, cryptorchidism, and congenital heart disease. Mutations of RAB23, encoding a small GTPase that regulates vesicular transport, are present in the majority of cases. Here, we describe a disorder caused by mutations in multiple epidermal-growth-factor-like-domains 8 (MEGF8), which exhibits substantial clinical overlap with Carpenter syndrome but is frequently associated with abnormal left-right patterning. We describe five affected individuals with similar dysmorphic facies, and three of them had either complete situs inversus, dextrocardia, or transposition of the great arteries; similar cardiac abnormalities were previously identified in a mouse mutant for the orthologous Megf8. The mutant alleles comprise one nonsense, three missense, and two splice-site mutations; we demonstrate in zebrafish that, in contrast to the wild-type protein, the proteins containing all three missense alterations provide only weak rescue of an early gastrulation phenotype induced by Megf8 knockdown. We conclude that mutations in MEGF8 cause a Carpenter syndrome subtype frequently associated with defective left-right patterning, probably through perturbation of signaling by hedgehog and nodal family members. We did not observe any subject with biallelic loss-of function mutations, suggesting that some residual MEGF8 function might be necessary for survival and might influence the phenotypes observed
Interview with Joseph Carpenter
No full textLieutenant Colonel Joseph Carpenter, a native of Washington, D. C., joined the Corps in 1943 after finishing high school. He served stateside as a clerk until 1946, when he was discharged. After receiving a college degree, he re-entered the Corps in 1956, obtained a commission, and, working primarily with data processing, rose to the rank of Lieutenant Colonel. He lives in retirement in Washington, D. C

Developments in the hydrogenation of challenging substrates utilising transition metal complexes
No full textThis thesis describes the developments of new protocols for the hydrogenation of challenging substrates. Three specific substrates were highlighted for study after an initial review of the literature; benzofurans, esters and bulky ketones.
Chapter 1 details a review of the hydrogenation of challenging unsaturated substrates, highlighting areas where development is still required.
Chapter 2 describes studies on the hydrogenation of 2,3-benzofuran. While a benzofuran hydrogenation catalysts was optimised, severe conditions were required to facilitate the reaction, and not found to be applicable for more elaborate substrates. We therefore considered an alternative process of enantioselective hydrogenation of benzofuranyl ketones followed by heterogeneous hydrogenation. A good process for transfer hydrogenation of a range of these hitherto unstudied substrates was developed along with greater understanding.
The hydrogenation of esters is another challenge in the catalytic reduction field, so was also selected for study, with the results described in Chapter 3. After screening a range of catalysts of types [RuCl₂ (diphosphine)(diamine)] and [RuCl₂ (PNX)(DMSO)], good catalysts were identified. Successful hydrogenation of a range of esters, under mild conditions was achieved using [RuCl₂ (1,3-bisdiphenylphosphinepropane)(2-aminomethylpyridine)] using high concentrations of base co-catalyst. [RuCl₂ ((2-(diphenylphosphanylbenzyl)ethane-1,2-diamine)(DMSO)] combined with 15-25 mol% of a basic co-catalyst have been shown to be active at near ambient conditions in the hydrogenation of aromatic esters.
Chapter 4 related to studies where the activity of Ru, Ir and Rh complexes of the same tridentate ligand were tested in the hydrogenation of ketones that would be regarded as sluggish substrates. Highly active and selective catalysts for the hydrogenation of bulky acetophenone derivatives were found using iridium complexes of PNX ligands (formed in situ). The highest selectivity was obtained with acetophenone substrates containing iso-propyl and cyclohexyl substituents, or medicinally important piperdinyl groups. In the best cases over 90% e.e. was observed with high conversions and with only 0.1 mol% of catalyst
William Morris and Edward Carpenter: back to the land and the simple life, 1880-1910
No full textThis thesis focuses on the influence of William Morris and Edward Carpenter on
aspects of the back-to-the-land and simple-life movements between the years 1880-
1910. Specifically, it seeks to define and explore the convergence and divergence of
both writers' return-to-nature ideology, and considers their influence on the
development of particular groups, who represented some of the multiplicity of backto-
the-land ideas and experiments current during this period. The thesis is divided
into three main parts; the intellectual framework for the study is broad, and takes into
account the historical context, the cultural significance and the character of the
material in each section.
The first part of the thesis undertakes an expository evaluation of key texts
from Morris's and Carpenter's political journalism, lectures and imaginative writing,
examining how both writers developed an appropriate language to convey their
social and political ideals. The critical method employed uses detailed textual
analysis, identifying and discussing the individual qualities of Morris's and
Carpenter's back-to-the-land writing, and reflecting on the differing emphases of
their utopian rhetoric. The second part of the research explores the take-up of
Morris's and Carpenter's ethos in four diverse and little known late-nineteenthcentury
journals, concerned with simple-life issues and a return to the land, namely
Seed-time, The New Order, Land and Labor and Land and People. It employs the
thinking of Pierre Bourdieu and Mikhail Bakhtin to establish an appropriate balance
between critical theory and empirical study. Lastly using a historical and descriptive
method the thesis uses archival material to examine the nature and extent of both
writers' influence on two Cotswold back-to-the-land experiments - the Whiteway
Colony and the Chipping Campden Guild of Handicraft. These provide a particular
opportunity to consider and compare the practical outcomes of return-to-the-land and
simple-life ideologies.
The study extends scholarship in this area by significantly re-appraising the
relationship between Morris's and Carpenter's back-to-the-land writing, and reinstating
Carpenter as a germinal influence. It also increases our understanding of the
values and function of the journals in the study, and establishes an insight into the
wider cultural assimilation of both writers' ideals
