Comparison between clinical results of two diffractive multifocal lenses with the same platform but different additions

PURPOSE: To evaluate visual results with two multifocal diffractive lenses designed with the same platform but with different additions. SETTING: Grupo Innova Ocular clinics. METHODS: A total of 50 eyes from 50 patients were included. Group 1 (n = 25) was implanted with the TECNIS® 1 ZLB +3.25 and group 2 (n = 25) with the TECNIS® 1 ZKB +2.75. Patients were assessed at 24 hours, 1 week and 1 month postoperatively. At surgical discharge, corrected (CDVA) and uncorrected distance visual acuity (UCDVA), near visual acuity (VA) at 25, 40 and 80 cm, visual quality and the defocus curve were measured. RESULTS: Changes in sphere and spherical equivalent were statistically significant (p<0.01) in both groups at 1 week and 1 month compared to preoperative values. In group 1, UCDVA logMAR at 1 month was 0.06 ± 0.02. In group 2, UCDVA at 1 month was 0.03 ± 0.03. In near vision, the TECNIS® 1 ZLB group obtained a VA logMAR of 0.35 ± 0.02 at 25 cm, 0.13 ± 0.02 at 40 cm and 0.27 ± 0.02 at 80 cm, while in the TECNIS® 1 ZKB group, the values were 0.38  ± 0.03, 0.14 ± 0.03 and 0.23 ± 0.06, respectively. No statistically significant differences were found either when results for visual quality were compared. CONCLUSION: Both the TECNIS® 1 ZLB and TECNIS® 1 ZKB are excellent options for obtaining good distance and near vision, in addition to providing good intermediate vision, especially at distances such as those required for working with computers.

Remembering Liberal Feminism In Radical Ways: Locating Conservative Strategies In The Narratives Of Dr. Christina Hoff Sommers, Tammy Bruce, And Dr. Laura Schlessinger

This dissertation identifies and challenges post-feminist narratives that remember the second wave or 1960s and 1970s liberal feminism as a radical form of activism. The narratives of three prominent post-feminist authors: Dr. Christina Hoff Sommers, Tammy Bruce and Dr. Laura Schlessinger are used as examples of how identification works as a rhetorical device that motivates individual actors to join in a struggle against liberal and radical feminist ideologies. I argue that each author draws on classically liberal and politically conservative virtues to define a "true" feminism that is at odds with alternative feminist commitments. I demonstrate how these authors create a subject position of a "true feminist" that is reminiscent of the classically liberal suffragist. In Burkean terms, each author constitutes the suffragist as a friend and juxtaposes her with the enemy--modern liberal and radical feminists. I articulate the consequences of such dialectical portrayals of feminist activism and further suggest that these authors' visions of feminism reinforce patriarchal practices, urging women to assimilate into a classically liberal society at the cost of social justice. In opposition to their memories of feminism, I offer a radical democratic approach of remembering feminism that is less concerned with the definition of feminism or feminist than it is with holistically addressing oppression and what oppression means to subjugated populations.

"Another Way": The Pneumatology of Deleuzean Minoritarian Communal Interpretation in Scripture, the 16th Century Radical Reformation, and Alternative 21st Century Anabaptist Community

This dissertation proposes a constructive theology of the Holy Spirit called the "pneumatology of minoritarian communal interpretation," the alternative creation of meaning within an oppressive majority context. It illustrates the convergence of Deleuzean philosophy with Anabaptist pneumatology and media communal interpretation theory in three particular locations: 1) selected mentions of the Holy Spirit in the Hebrew Bible and Christian New Testament; 2) the 16th century Radical Reformation; and 3) "Another Way," a 21st century alternative Anabaptist group focused around the spiritual discussion of art and popular media. Chapter One outlines the three theories. Chapter Two examines the Holy Spirit in the Hebrew Bible, particularly 1 Samuel 8, the book of Ezekiel, and the Gospel narratives. Chapter Three examines the pneumatological writings of the Radical Reformers, concentrating particularly on their theologies of the intersection between church and the surrounding majoritarian culture. Chapter Four outlines my original field research with Another Way, and examines the tension between minoritarian communal interpretation and the 21st century semiotic regime. Chapter Five then summarizes the conversations between theory and illustration to propose the pneumatology of minoritarian communal interpretation for Christian theology.

Bifunctional primary amine 2-aminobenzimidazole organocatalyst anchored to trans-cyclohexane-1,2-diamine in enantioselective conjugate additions of aldehydes

Bifunctional chiral primary amine 8 containing an (S,S)-trans-cyclohexane-1,2-diamine scaffold and a 2-benzimidazole unit is used as a general organocatalyst for the Michael addition of α,α-branched aldehydes to nitroalkenes and maleimides. The reactions take place, with 20 mol % of catalyst in dichloromethane at rt for nitroalkenes and with 15 mol % catalyst loading in toluene at 10 °C for maleimides, in good yields and enantioselectivities. DFT calculations demonstrate the bifunctional character of this organocatalyst activating the aldehyde by enamine formation and the Michael acceptor by double hydrogen bonding.

Overcoming performance and convergence issues of discrete transform based modeling of crosslinking classical and reversible deactivated radical polymerizations

Population balances of polymer species in terms 'of discrete transforms with respect to counts of groups lead to tractable first order partial differential equations when ali rate constants are independent of chain length and loop formation is negligible [l]. Average molecular weights in the absence ofgelation are long known to be readily found through integration of an initial value problem. The extension to size distribution prediction is also feasible, but its performance is often lower to the one provided by methods based upon real chain length domain [2]. Moreover, the absence ofagood starting procedure and a higher numerical sensitivity hás decisively impaired its application to non-linear reversibly deactivated polymerizations, namely NMRP [3].
