2025ArkhipovSV. Human Children

The monograph Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. An essay with references to interactive materials. 2nd revised and expanded edition. Joensuu: Author's Edition, 2025. [In Russian]. The monograph dates the writing of the Book of Genesis and the events depicted in it, as well as refutes the authorship of Moses. I offer mutually beneficial cooperation (50/50) in literary translation into English or native language. Proofreading of machine translation and cooperation in editing are expected. Requirements for co-author: 1. Native speaker 2. Experience as a writer. E-mail: archipovsv(&)gmail.com Annotation The first version of the Book of Genesis appeared in Ancient Egypt approximately 3,600 years ago, during the Hyksos period. The work was conceived as a fairy tale epic. An unknown physician-encyclopedist, who is also presumed to have authored the Edwin Smith Papyrus, played a role in its composition...

F. Pauwels vis-à-vis S. Arkhipov ☺

F. Pauwels vis-à-vis S. Arkhipov ☺ F. Pauwels (1965), when developing the theory of biomechanics of the hip joint, did not take into account the ligaments. More than 20 years after I first tried to fill this aspect in experiments: https://kruglayasvyazka.blogspot.com/2024/06/blog-post_8.html https://kruglayasvyazka.blogspot.com/2024/06/blog-post_31.html #ligamentum_teres #ligamentum_capitis_femoris #hip #biomechanics Publication in the facebook group 03/28/2025.

BIOMECHANICS OF THE HIP JOINT WITHOUT LCF

Biomechanics of the hip joint without LCF Do you remember the comparison of the ligamentum teres with the spring element of a cart? ( 1874SavoryWS ). An analogy could arise after reading the book Bell J. The Principles of Surgery (1801) . Most orthopedists still think so. For more details see: https://roundligament.blogspot.com/2024/04/1836-1840partridger.html & 1836-1840PartridgeR (remembering the history of orthopedics) #ligamentum_teres #ligamentum_capitis_femoris #hip #biomechanics Publication in the facebook group 03/28/2025. ...

HIP JOINT MODEL WITH LCF ANALOGUE

hip joint model with an analogue of the ligamentum capitis femoris One of the first mechanical models of the hip joint with a ligamentum capitis femoris analogue: experimental study of motion (approximately twenty years ago), see: https://kruglayasvyazka.blogspot.com/2024/06/1.html , https://kruglayasvyazka.blogspot.com/2024/06/blog-post.html #ligamentum_teres #ligamentum_capitis_femoris #hip #biomechanics Publication in the facebook group 03/26/2025.

FIRST EXPERIMENTS ON A MECHANICAL MODEL

First Experiments on a Mechanical Model Twenty-five years ago, the first mechanical model of the hip joint was made for experimental research. At first, it contained analogues of the acetabular labrum and external ligaments: https://kruglayasvyazka.blogspot.com/2024/05/blog-post_66.html https://kruglayasvyazka.blogspot.com/2024/05/blog-post_31.html https://kruglayasvyazka.blogspot.com/2024/05/blog-post_48.html #ligamentum_teres #ligamentum_capitis_femoris #hip #biomechanics Publication in the facebook group 03/25/2025. ...

A FORCE THAT HELPS ROTATE THE PELVIS

VISUALIZATION OF THE LCF BY THE MEDIAL APPROACH

Visualization of the ligamentum capitis femoris by the medial approach in experiment … and in reconstruction? Movement of the ligamentum capitis femoris when walking and in various poses. Experiments by J. Struthers (1858) in our modification; see description and illustrations: Pt 1 https://kruglayasvyazka.blogspot.com/2024/05/blog-post_28.html Pt 2 https://kruglayasvyazka.blogspot.com/2024/05/blog-post_17.html #ligamentum_teres #ligamentum_capitis_femoris #hip #biomechanics Publication in the facebook group 03/23/2025.

THE LOADING ACTING ON THE FEMORAL HEAD

The loading acting on the femoral head during standing on one leg Simple experiments demonstrating the role of ligamentum capitis femoris were inspired by Frederick Pauwels; see description and illustrations: https://kruglayasvyazka.blogspot.com/2024/05/blog-post_27.html Publication in the facebook group 03/22/2025. #ligamentum_teres #hip #ligamentum_capitis_femoris BLOG CONTENT NEWS AND ANNOUNCEMENTS FACEBOOK

Planar models of the hip joint

Planar models of the hip joint: The history of creation and experiments. For a description of experiments on a planar model of the hip joint with ligamentum capitis femoris (+ 25 illustrations), see: https://kruglayasvyazka.blogspot.com/2024/05/blog-post_26.html NB! In experiments on planar models, F. Pauwels did not take into account ligaments. Therefore, his theory is not correct as applied to the norm.
