Abstract:

Background and Aim: During post-amputation recovery or rapid body mass change, residual limb volume can change quickly, requiring frequent adjustments or replacement of the socket to maintain fit. The aim of this pilot test was to evaluate the feasibility of using a three-dimensional-printed insert to extend the service life of a prosthetic socket after substantial residual limb volume loss. Technique: One research subject with a well-fitting transtibial prosthetic socket had an oversized socket fabricated to simulate substantial limb volume loss. The digital shapes of the oversized and well-f

Abstract:

Inserts supporting run-flat tire is a key technology in the field of vehicle active safety. When the vehicle is under zero driving condition, the deformation of the inserts supporting run-flat tire due to compression can cause the tire to be crushed, and loss of adhesion between the tire and rim can lead to separation. These situations can reduce the cruising ability of the vehicle. Under zero driving condition, the insert, which is the main support body for the tire, could rub against the inner part of the tire sharply, thereby generating heat in the tire. Heat in the tire is difficult to dis

Abstract:

HIV-1 strains that possess a one or two amino acid insert between codons 102 and 103 of the reverse transcriptase (RT) gene were identified in three HIV-1-infected individuals. Each strain also had one or more known mutations associated with nucleoside RT inhibitors (NRTIs) and non-nucleoside RT inhibitors (NNRTIs). Recombinant viruses from these strains had reduced susceptibility to efavirenz and nevirapine, and homology modelling predicted a loss of binding contacts with efavirenz. Mutagenesis studies indicated that replication of insert-containing strains was dependent on RT gene mutations

A method for predicting cooling air flow rates using tests on cylindrical models of typical turbine blade leading edges has been extended to include blades with inserts and blades with reversed-angled holes.

Calculated and experimentally determined flow rates are compared with good agreement. The second experiment was performed to determine internal loss coefficients for reverse-angled holes oriented so the flow makes a revers

It is known that during the cutting process the tool wears out. This is due to the high temperatures, the relative velocities and shocks between the contact surfaces of the tool-part and the mechanical and thermal stresses which appear on the active surfaces of the tool. The result is loss of cutting and reduced processing quality. This involves taking measures to increase the values of the cutting tools and/or the durability of their cutting inserts.

— Unicompartmental knee arthroplasty (UKA) is a surgical method used to treat osteoarthritis in one portion of the knee, most often the medial compartment. UKA supporters argued that the procedure more closely replicates natural knee kinematics, results in reduced perioperative morbidity and intraoperative blood loss, and allows for quicker mobility and rehabilitation than traditional bicondylar knee arthroplasty. The goal of this study is to look at the impact of implant design on the mechanics of unicompartmental knee arthroplasty (UKA). 3D models of the UKA implant were modified from three

The excess noise contributed by the inter-core crosstalk between cores can be effectively suppressed by quantum channel wavelength management, leading to the performance improvement of the MCF-based CVQKD system.

This complex structure is consistent with putative local genomic instability.

At the present stage of development of the railway transport infrastructure, the construction of double-track inserts can be considered as the first stage of strengthening the throughput and carrying capacity before the construction of the second continuous main tracks. In this study, the regulatory documentation that establishes the procedure for calculating and analyzing the capacity of double-track crossings is analyzed, dependent, conditionally independent and unaccounted factors affecting the capacity are classified.

AbstractWe hypothesized that a total knee arthroplasty (TKA) with an intraoperative tibial force greater than the tibial force of the native knee has signs of stiffness as measured by loss of extension and flexion, and anterior translation of the tibia. Intraoperative forces in the medial and lateral tibial compartments were measured during passive motion in 71 patients treated with calipered kinematically aligned TKA. Maximum extension, flexion, and the anterior–posterior position of the tibia with respect to the distal femur at 90 degrees of flexion were measured. Measurements were repeated

Purpose: Epitheses (facial prostheses) for large facial tissue defects manufacturedfrom silicones exhibit unsatisfactory rigidity and its stiffening is required, which createstechnological problems. Moreover, facial epitheses have to be replaced in a relatively shortperiod of use which creates a significant costs, often impossible to realize. The hypothesisof the study was that with use of additive manufacturing is possible to obtain the reusableform for thermoforming of the stiffening insert of auricular prosthesis and the mould whichallows multiple casting of silicone prosthesis with the ins

Abstract:

The influence of the mechanical characteristics of certain insole materials in the generation and transmission of heel strike impacts while walking was studied. Three insole materials were selected according to their mechanical characteristics under heel strike impacts. The selection of materials has made it possible to distinguish the effect of rigidity and loss tangent in the transmission of heel strike impacts. A lower rigidity and a high loss tangent have been shown to reduce the transmission of impacts to the tibia. A low rigidity was seen to significantly increase the transmission of imp

Abstract:

Opaque face masks harm communication by preventing speech-reading (lip-reading) and attenuating high-frequency sound. Although transparent masks and shields (visors) with clear plastic inserts allow speech-reading, they usually create more sound attenuation than opaque masks. Consequently, an iterative process was undertaken to create a better design, and the instructions to make it are published. The experiments showed that lowering the mass of the plastic inserts decreases the high-frequency sound attenuation. A shield with a clear thermoplastic polyurethane (TPU) panel had an insertion loss

In this paper, a complicated resistance muffler was designed for a construction machinery. Computational Fluid Dynamics (CFD) method with three dimension models was used to explore the aerodynamic performance of the muffler. With this method the pressure distribution in the muffler is simulated and the pressure loss is predicted for the structure modification. The experiment results verify that the assembly performance of the muffler modified is better than the original muffler.

Abstract:

In order to enhance heat transfer processes in elements of power equipment with minimal energy consumption, the concept of partial structure formation of the heat transfer surface was developed. To determine the energy efficiency of partial structure formation of the heat transfer surface with transitional Reynolds numbers, the surface in the form of spiral corrugation is considered. Partial spiral corrugation due to a change in the flow structure makes it possible to increase the convective component of heat transfer with a moderate increase in friction loss in a transient flow regime.

Then, five copies of back-to-back connected transitions are fabricated on RT/Duroid 5880 substrate.
