No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Get PDFBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Alfonso Muzzarelli e l’autunno dell’Illuminismo a Ferrara
No full textSi presenta l'ampia produzione del gesuita farrarese Alfonso Muzzarelli, che fu uno dei più tenaci e coerenti avversari delle idee illuministiche. In particolare vengono proposte le sue critiche all'enciclopedismo di d'Alembert e all'"Emilio" di Rousseau. Muzzarelli seguì Pio VII in Francia nel suo esilio

Spray-drying of solutions containing chitosan together with polyuronans, and characterization of the microspheres.
No full textDibutyryl chitin obtained by esterification with butyric anhydride and regenerated chitin obtained from dibutyryl chitin by saponification,
both in the form of wet-spun fibres and non-wovens, were examined by infrared spectrometry and X-ray diffraction spectrometry. Chitin
fibres and chitosan fibres were also studied for comparison, and found to maintain the XRD spectral features of the parent chitin and chitosan.
On the opposite, DBC fibres and non-woven exhibited depressed crystallinity, the peak at 0.46–0.47 nm, typical of chitin, being hardly
detectable, while the one usually at ca. 1.00 nm was present at ca. 1.20 nm. Both DBC fibres and non-woven were highly oriented. When
exposed to porcine pancreatic lipase or wheat germ lipase, the DBC fibres gained improved crystallinity with peaks at 1.14–1.18 and
0.41 nm, due to partial regain of chitin structure as a consequence of partial enzymatic removal of butyryl groups, as confirmed by ATRFTIR.
The RC fibres exhibited broad XRD peaks at 0.96 and 0.36 nm; sharper peaks at 0.34, 0.46–0.49 and 0.96 were observed after
exposure to lipases, due to removal of a disordered polymer fraction susceptible to the unspecific enzymatic depolymerization. In fact the RC
fibres were found to have 8% lower degree of acetylation compared to parent chitin, as a consequence of the alkaline regeneration treatment.
In conclusion, these modified chitins are scarcely susceptible to degradation by lipases (besides to lysozyme, as already reported in the
literature); therefore their biochemical significance in wound management seems limited. They, however, appear to be the ideal textile
materials for providing mechanical support to freeze-dried chitosan sponges having amply documented activity in wound healing, and for the
preparation of specialty textiles
Alkaline chitosan solutions
No full textRigid and transparent hydrogels were obtained upon pouring chitosan salt solutions into saturated ammonium hydrogen carbonate. Incubation at 20°C for 5 days yielded chitosan carbamate ammonium salt, Chit-NHCO2 -NH4 + a chemical species that either by hydrolysis or by thermal treatment decomposed to restore chitosan in free amine form. Chitosans of different degrees of acetylation, molecular sizes and origins (squid and crustaceans) were used as hydrochloride, acetate, glycolate, citrate and lactate salts. Their hydrogels obtained in ammonium hydrogen carbonate yielded chitosan solutions at pH values as high as 9.6, from which microspheres of regenerated chitosans were obtained upon spray-drying. These materials had a modest degree of crystallinity depending on the partial acylation that took place at the sprayer temperature (168°C). Citrate could cross-link chitosan and impart insolubility to the microspheres. Chloride on the contrary permitted to prepare microspheres of chitosan in free amine form. By the NH4HCO3 treatment, the cationicity of chitosan could be reversibly masked in view of mixing chitosan with alginate in equimolar ratio without coacervation. The clear and poorly viscous solutions of mixed chitosan carbamate and alginate were spray-dried at 115°C to manufacture chitosan-alginate microspheres having prevailing diameter approx 2 micron
Le donne e la fotografia
No full textIl rapporto tra le donne e la fotografia poggia le sue basi su una storia affascinante. In primo luogo perché questa storia muove i primi passi a cavallo del XIX e del XX secolo, in un periodo estremamente ricco di trasformazioni sociali, culturali ed economiche. Un periodo in cui avvengono e vengono elaborate gran parte delle rivoluzioni tipiche delle società moderne che oggi, in età postmoderna appunto, ancora viviamo. In secondo luogo perché, nella storia dell’incontro tra donne e fotografia, un nuovo strumento tecnologico diventa per la prima volta l’alleato naturale di una “minoranza” fino a quel momento negata e dimenticata dalla Storia, e che ora coltiva invece esplicitamente ambizioni artistiche e rivendicazioni di autonomia professionale che, in quello strumento, trovano sfogo. Infine, nella storia delle donne e la fotografia, è come se due universi assetati di novità e mossi dal desiderio di progresso si fondessero insieme, intrecciando i propri destini in una pratica simbiotica d’inedita forza. Questa forza inedita è data proprio dalle comuni difficoltà in cui si trovano a muovere entrambi gli universi. La fine dell’Ottocento e l’inizio del Novecento rappresentano, infatti, per la storia delle donne, la prima ondata di Femminismo storico e la battaglia dei diritti, la richiesta di emancipazione sociale e l’emersione politica. Per la storia della fotografia quel periodo è invece la fase aurorale dei grandi pionieri e dell’impegno volto a migliorare e sviluppare una tecnica ancora imperfetta
