At the core of this article and publication are archived documents, namely, letters of A. Smirnov to T. Shchepkina-Kupernik, their collection kept at the Russian State Archive of Literature and Art (RGALI). Collaboration between the Shakespeare scholar and the translator lasted for over 30 years (1916–1947). This epistolary legacy is rich in different philological subjects, including Smirnov’s and Shchepkina-Kupernik’s joint preparation of Shakespeare’s works to be printed for adult as well as younger audiences (for example, the collected works for children in four volumes, which features the first publication of Shchepkina-Kupernik’s translation of Romeo and Juliet, produced on Smirnov’s request). It is Shchepkina-Kupernik’s work on the tragedy that the author attempts to piece together in the article. The correspondence also prompts a broader question about the translatororiented editions of Shakespeare prepared for print by Smirnov in the late 1930s. The commentary supplied to the correspondence offers a reconstruction of A. Smirnov’s wide network of contacts in the cultural and publishing setting in the grim period of 1930s political repression.

ABSTRACT U.S. Coast Guard (USCG), U.S. Environmental Protection Agency (USEPA), and California Department of Fish and Wildlife (CDFW), Office of Spill Prevention and Response (OSPR) agreed to the joint preparation of oil spill contingency plans following the enactment of California and federal laws in 1990. With little guidance initially, six Area Committees embarked on a new process to create the first coastal Area Contingency Plans (ACPs) in 1992. In 2015, when emergency regulations to expand OSPR's jurisdiction statewide became effective, developing inland Geographic Response Plans (GRPs) became a top priority. Over the last 30 years, the ACPs have evolved into robust, nationally recognized planning documents, and response plans have expanded into inland environments. This paper will describe in detail the contributions and advancements in California oil spill contingency planning over 30 years. It will highlight OSPR's approaches for statewide consistency and coverage, interoperability between various state and federal plans, tools (including Geographic Information System (GIS) and various databases), improved sensitive site contacts and management, and lessons learned. It will also cover goals for future improvements in both marine and inland contingency plans.

We present a technical surgical description of a 36-year-old female diagnosed with Progressive Collapsing Foot Deformity (PCFD) treated with a medial displacement calcaneus osteotomy, a lateral column lengthening, and a modified Lapidus fusion. In order to increase the plantar flexion power of this arthrodesis and minimize the loss in ray length with joint preparation, a bone block structured graft was used. Fixation was performed using a post implant in the medial cuneiform with crossing screws though the surfaces and the graft. Forefoot varus was properly corrected intraoperatively by using the described surgical technique. Satisfactory functional short-term results and an excellent alignment was accomplished. Level of Evidence V; Therapeutic Studies; Expert Opinion.

Currently, joint sealant is designed without consideration of the bond strength between the concrete and the sealant and the effect of shape on stress concentration. This often leads to adhesive failures within 1.5 years, earlier than the expected service life of the joint sealant, which is 20 years. In adhesive failure, the strength of the bond and the stress of the interface between the sealant and the face of the joint reservoir play a very important role. To examine the nature of the bond along the sealant/joint well interface, experimental bond tests were conducted. In addition, the stress distribution on the interface was also investigated according to geometry (Shape Factor [SF] and degree of curvature [DoC]). Re-evaluation of the SF was conducted, and a new design factor, DoC, was introduced and investigated through the finite element method of analysis. With these factors, the reduction of bond strength and increase in the stress at the interface can be limited reducing the potential for early adhesive failure. Based on this study, the effect of joint preparation (dirt and moisture) on joint strength and shape (SF and DoC) of joint sealant should be considered when designing and installing sealants.

Category: Bunion; Midfoot/Forefoot; Other Introduction/Purpose: Potential shortening of the first ray is an important consideration when performing a first tarsometatarsal (TMTJ) fusion. However, no previous study has sought to directly quantify the resultant shortening after TMTJ fusion. The purpose of the present anatomic study was to directly assess and compare shortening of the first ray using two joint preparation techniques (curettage, planal resection) for first TMTJ fusion. Methods: Ten pairs of matched lower extremity cadaver specimens were divided into two groups. Preoperative length assessments were performed at the first TMTJ dorsally and plantarly using a digital caliper. In Group 1, joint preparation for first TMTJ fusion was performed with curettage, whereas specimens in Group 2 underwent planal resection. Post-operative length assessments were repeated. All data was analyzed using two-tailed Students t-tests. Results: Mean shortening of the first ray following curettage was 1.1 (range, 0.3 to 2.0) mm dorsally and 1.6 (range, 0.6 to 3.7) mm plantarly; while mean shortening following planal resection was 4.5 (range, 2.7 to 7.9) mm dorsally and 4.6 (range, 2.4 to 8.9) mm plantarly. The measured differences were statistically significant (p <0.001, p=0.001). Conclusion: Both curettage and planal resection resulted in shortening of the first ray after first TMTJ fusion. Planal resection resulted in significantly more shortening, which was also more variable. Surgeons performing first TMTJ fusions may consider curettage over planal resection to mitigate the risk of painful postoperative transfer metatarsalgia.
