Antegrade intramedullary (IM) nailing is the gold standard treatment for femoral shaft fractures; however, the non-union rate of infra-isthmal femoral shaft fractures is still high after antegrade IM nailing. This retrospective case–control study aimed to determine the association between perioperative radiographic factors and the non-union of infra-isthmal femoral shaft fractures after an…
Metal and metal oxide nanoparticles have attracted increased attention due to their unusual physical and chemical properties. The nature, dispersion, and size of the nanoparticles are key factors in determining the activity and selectivity of the supported catalyst
"This book is a collection of essays on Bob Dylan and religion. The eight scientific essays present new perspectives on the subject, aiming to elucidate the role played by religion in Bob Dylan's artistic output and in the reception history of some of his songs. Few would dispute the fact that religion or religious traditions and the use of religious imagery have always played an important r…
"This new and expanded edition is intended to help candidates prepare for entrance examinations in mathematics and scientific subjects, including STEP (Sixth Term Examination Paper). STEP is an examination used by Cambridge Colleges for conditional offers in mathematics. They are also used by some other UK universities and many mathematics departments recommend that their applicants practice on…

Kepulauan Inggris dan Irlandia menguji kemampuan adaptasi dan fleksibilitas yang diklaim sendiri dari Serikat Yesus yang baru. Misi ke Irlandia menyoroti kompleksitas dan berakhir dengan kegagalan pada awal tahun 1580-an, tidak dihidupkan kembali hingga tahun 1598. Misi Jesuit yang legendaris ke Inggris pada tahun 1580, yang digagas dengan optimisme yang merindukan, dibaptis dengan darah dengan…
This paper systematically reviews the research progress in the field of the influence of air pollutants in the engine inlet on the accelerated wear of the elements of the association: piston, piston rings, cylinder liner (P-PR-CL), and plain bearing (journal–panel). It was shown at the outset that the primary component of air pollution is road dust
Internal combustion engines remain as the main propulsion system used for ground trans‐ portation, and the number of successful developments achieved in recent years is as varied as the new design concepts introduced
Background and Objectives: Aspirin (ASA) is a commonly used antithrombotic drug that has been demonstrated to reduce venous thromboembolism. The aim was to analyze if geriatric COVID-19 patients undergoing a 100 mg/day Aspirin (ASA) treatment prior to hospitalization differ in hospital outcome compared to patients without previous ASA therapy. Materials and Methods: An observational retrosp…
The motion of nonholonomic mobile manipulators (NMMs) is inherently constrained by joint limits, joint velocity limits, self-collisions and singularities. Most motion planning algorithms consider some of the aforementioned constraints, however, a unified framework to deal with all of them is lacking
