Background: To assess the clinical and functional outcome of surgically treated distal radius fractures specially involving volar rim fixed with Volar Rim Variable Angle Locking Plates. Objectives: To evaluate the radiological union in fractures of distal radius fixed with Volar Rim Variable Angle Locking Plates .To evaluate clinical and functional outcome associated with this treatment modality. To study the complications associated with this treatment. Materials and Methods: 20 cases of distal end radius fractures surgically treated with Volar Rim Variable Angle Locking Plate according to inclusion and exclusion criteria, all patients followed up for a period of 1 year and results assessed with using the Demerit point system of Gartland and Werley. Results: In our study mean duration of complete union was 11 weeks which is comparable with other similar studies. We have achieved excellent results in 65% of cases, good in 20% of cases, fair in 10% and poor results in 5% of cases. Complications like stitch abscess, reduced range of motion, complex regional pain syndrome seen in 4 (20%) of cases.

INTRODUCTION AND AIM: This study aims to evaluate the functional and radiological outcomes in unstable distal end radius fractures treated with variable angle locking plates. MATERIAL AND METHODS: We reviewed 20 unstable distal end radius fractures that were operated and xed with variable-angle locking plate. RESULTS: According to Green and O'Brien Score (Cooney's modication) , excellent results were reported in 70 %,while good results were present in 20% cases, fair results were seen in 10% cases. CONCLUSION: The use of variable angle locking plates (VALP) in treating unstable distal end radius fractures is associated with excellent to good functional outcomes with minimal complications. VALP allows subchondral purchase in the articular fragments due to the exibility in the implant as far as plate positioning (that can be placed even beyond watershed line for very distal radius fractures) and as far as screw positioning in different directions (that can hold various distal fracture fragments as well as styloid process fracture). By this way, VALP helps in maintaining the reduction and predictably yields better functional outcome especially in unstable distal end radius fractures with early return to pre-injury occupation.

Remote sensing target tracking in satellite videos plays a key role in various fields. However, due to the complex backgrounds of satellite video sequences and many rotation changes of highly dynamic targets, typical target tracking methods for natural scenes cannot be used directly for such tasks, and their robustness and accuracy are difficult to guarantee. To address these problems, an algorithm is proposed for remote sensing target tracking in satellite videos based on a variable‐angle‐adaptive Siamese network (VAASN). Specifically, the method is based on the fully convolutional Siamese network (Siamese‐FC). First, for the feature extraction stage, to reduce the impact of complex backgrounds, we present a new multifrequency feature representation method and introduce the octave convolution (OctConv) into the AlexNet architecture to adapt to the new feature representation. Then, for the tracking stage, to adapt to changes in target rotation, a variable‐angle‐adaptive module that uses a fast text detector with a single deep neural network (TextBoxes++) is introduced to extract angle information from the template frame and detection frames and performs angle consistency update operations on the detection frames. Finally, qualitative and quantitative experiments using satellite datasets show that the proposed method can improve tracking accuracy while achieving high efficiency.

Background: The DePuy Synthes variable angle LCP® Volar RIM Plate has been designed with its contour to overhang volar rim fragments of the distal radius to prevent secondary displacement after fracture fixation. Therefore, RIM potentially contributes to a risk of flexor tendon rupture due to its plate prominence over the watershed line. This is a retrospective cross-sectional study that aims at describing the occurrence of complications by utilizing RIM as well as three standards VLPs to evaluate the impact of plate design on flexor tendons. Methods: A total of 84 patients with a volar locking plate fixation were analyzed retrospectively (Far-distal; RIM: 14 cases, Juxta-articular; AcuLoc2 (ACUMED): 20 cases, Dual-Loc V7 (MEIRA): 25 cases, Extra-articular; VA-TCP (DePuy Synthes): 25 cases). Tendinous problems were evaluated with a reported adverse event and flexor tendon appearance examined by utilizing ultrasonography and direct observation during hardware removal. Plate prominence was graded according to Soong’s classification and the distance to flexor tendons was measured to describe the risk that each plate damage the flexor tendons. Results: The mean follow-up period was 13.0 months. All RIM plates were placed in grade 2 (85.7%) and grade 1 (14.3%). Symptomatic and asymptomatic tendinous problems were barely reported in RIM. The examination of ultrasonography and direct observation during hardware removal showed that tendons smoothly slid without attrition on the curved plate surface of RIM despite their adjacent appositions came from its high and distal plate prominence. Conclusions: Smooth profile of RIM showed an ability to decrease the potential risk of flexor tendon damage regardless of its prominence over the watershed line. RIM can be applied more to challenging far distal fractures when used judiciously and surgeons need to be even more vigilant for symptoms of tendon irritation as usually recommended without being coward more than necessary.

Diagrid structures are popular among engineers and architects. The reason for this is its structural efficiency due to carrying both lateral loads and gravity loads and aesthetic attributes. Recent research has shown that using variable angle diagrids for a structure can be more efficient than using diagrid structures with constant angle of inclination. This paper provides an analysis of different configurations of the variable angle diagrid structures. For this purpose, the parameters of variable angle diagrid structures such as angle of inclination of diagrids and the ratio of heights for which angle of inclination of diagrids are varied to study its effect on the structure. Different patterns of variable angle diagrid structures are generated for a 60 storied building which are modelled and analysed in ETABS under gravity and wind loads. The optimum configuration is selected from these diagrid configurations based on the structural weights of diagrids and performances of the building.

Background: The new low-profile plates and locking systems have popularized surgical options. Treatment modalities exist for surgical management of distal radius fractures, including open reduction and internal fixation (ORIF) with volar or dorsal plates and screws. Objectives: This study aimed to find a possible correlation between various parameters, either patient-related (age, bone quality) or fracture-related (type, reduction), and to analyze the impact of these factors on the radiological and clinical outcome of distal radius fractures treated by a variable-angle volar locking plate. Patients and Methods: The study included 18 patients suffering from fractures of the distal radius admitted to the Orthopedic Department in Zagazig University Hospital. All patients were operated from January 2019 to June 2019. A total of 18 patients complete at least 6 months follow up period. Results: The results were assessed according to the disabilities of arm, shoulder, and hand scoring system (DASH score), eight patients had excellent results with average 3.54 ±1.23, eight patients had good results with average 9.71 ±1.97. Conclusions: There was a negative correlation between patients’ age, sex, type of fracture, or presence of an associated ulnar styloid fracture and the final score. This correlation was statistically insignificant. A correlation was found between the affected dominant hand or number of rows of distal screws and the final functional score. this was found to be statistically significant.

Variable Angle Tow placement is a way to steer individual curvilinear fibers. This work presents the assessment of tensile behavior of open-hole composite laminates with Variable Angle Tow reinforcement. A new multi-scale finite element method, consisting of a microscale unit cell model and a macroscale gradient property model, is developed to simulate Variable Angle Tow structures with various fiber trajectories. The tensile strength and the failure process of open-hole reinforced laminates with Variable Angle Tow reinforcement under tensile loading are predicted and analyzed. Experiments are also conducted to investigate reinforcing efficiency and failure modes of the open-hole laminates. The comparison of predicted and experimental results for the tensile strength and failure modes of T700/Epoxy laminates demonstrates clearly that the mechanical behavior of Variable Angle Tow structure can be simulated very well by the proposed multi-scale model. Moreover, it is found that the tensile strength of Variable Angle Tow laminates is closely related to the eccentricity and it reaches the maximum value only when the trajectories of curvilinear fibers keeps consistent with maximum principal stress trajectories of the open-hole plate.

in the presented part of work the case with the angle of laying variable longwise of the reinforcing threads of a packer element in median and edge zones is investigated. Calculation of power characteristics of a cover of a packer element with various slopes is carried out. Tests of natural prototypes of covers the packer elements are carried out. The calculation results compared with data of an experiment are presented in the form of schedules with good degree of convergence. The developed technique allows to choose an optimum design of covers of a packer element with higher value of rigidity on face sites that ensures reliable functioning of a packer element at pressure differences in annular space.

the method of calculation of influence of design and technological parameters of material of a cover of a packer element is developed: the initial angle of laying of threads of the reinforcing framework, the packing density of threads in the field of unions, number of layers of a framework, rubber elastic modulus on power characteristics of a cover, for the purpose of creation of edge protection of a packer element. In the first part of work the cover of a packer element with laying of threads with a constant corner on all length of a cover is investigated. The received results of calculation, allowed to evaluate and prove quantitatively the constructive and technological directions of reliability augmentation of edge protection of a packer element. The developed calculation procedure is a basis of development of more general method of calculation of power characteristics of a cover of a packer element with variable longwise covers the initial angle of laying of threads.

Purpose The purpose of this paper is to study the adaptability of the tracked robot in complex working environment. It proposes an angle-changeable tracked robot with human–robot interaction in unstructured environment. The study aims to present the mechanical structure and human–robot interaction control system of the tracked robot and analyze the static stability of the robot working in three terrains, i.e. rugged terrain, sloped terrain and stairs. Design/methodology/approach The paper presents the mechanical structure and human–robot interaction control system of the tracked robot. To prevent the detachment of the tracks during obstacle navigation, a new type of passively adaptive device based on the relationship between the track’s variable angle and the forces is presented. Then three types of rough terrain are chosen to analyze the static stability of the tracked robot, i.e. rugged terrain, sloped terrain and stairs. Findings This paper provides the design method of the tracked robot. Owing to its appropriate dimensions, good mass distribution and limited velocity, the tracked robot remains stable on the complex terrains. The experimental results verify the effectiveness of the design method. Originality/value The theoretical analysis of this paper provides basic reference for the structural design of tracked robots.

The Generalized Softened Variable Angle Truss Model (GSVATM) allows one to compute the global behavior of reinforced concrete (RC) beams under torsion, including the pre- and post-cracking stage. In a previous study, such a model was successfully extended to cover prestressed concrete beams under torsion with longitudinal and uniform prestress. In order to continue to extend the theoretical model for other loading cases, in this article, the GSVATM is extended to cover RC beams under torsion combined with external and centered axial forces. The changes in GSVATM are presented, as well as the modified calculation solution procedure. Some theoretical predictions from the extended GSVATM are compared with numerical results from the non-linear finite element method (FEM), where good agreement is observed for the studied trends.

The axial constraint is an important constraint for the inversion of gravity data with which the dip information of the target geological bodies can be incorporated effectively. However, poor selection of the dip angles would inevitably lead to unreasonable inversion results. To reduce the errors caused by inappropriate angle estimation, this study proposes a new variable angle axial constraint for the inversion of gravity data. Moreover, to extend the utility of this new constraint, a method for employing multi-axial constraint is also introduced. The presented novel multi-axial constraint with a variable angle can be used to solve the inverse problems for complex geological bodies. We present a detailed iterative algorithm to solve the inverse problems with the presented constraints, in which the randomized singular value decomposition (RSVD) is used to solve the total objective function, and the generalized cross-validation (GCV) is utilized to estimate the regularization parameter. Numerous tests on synthetic gravity data with noise demonstrate that the inversion errors induced by inappropriate angle estimation can be greatly reduced by using the new constraints. Moreover, the presented methodology is successfully applied to a field data from the Morro do Engenho complex in the center of Brazil. This application also demonstrates the effectiveness of the proposed constraint.

Prestressed concrete (PC) is increasingly used nowadays for the construction of structures subjected to higher loads. Shear design of PC members is complicated and ambiguous as there is no rational and universally accepted shear design procedure. A comprehensive shear database of PC members helps researchers to understand the complicated and ambiguous shear design procedure. In the present study code provisions on shear design based on 45-degree truss analogy (IS 1343:2012 and ACI 318-14), Modified Compression Field Theory (AASHTO LRFD Design Specifications), Variable angle theory (EC-2) have been investigated along with newly proposed shear strength equations. A shear database covering the traditional shear failures of PC beams with stirrups has been developed to assess the shear strength and behaviour of PC beams. Out of 683 shear tests available from the literature on PC beams a total of 274 PC beams with stirrups has been investigated to assess the degree of conservativeness and accuracy of shear design code provisions and shear strength equations. Investigations on the shear code provisions with various variables that govern the shear strength show that serious attention should be given to the prediction of the accurate failure modes for the web-shear and flexure-shear critical specimens. The oversimplifications in the new shear strength equations have also been highlighted in the present study.

Shear design procedures should consistently provide accurate predictions across the range of practical applications, thus ensuring adequate safety and economically optimal designs. The best-estimate predictions of the operational Eurocode 2 Variable Strut Inclination Method (VSIM) of shear design are shown to be sensitive to the amount of shear reinforcement (Cladera & Mari, 2007). Compared to experimental results the unbiased predictions of VSIM tend to significantly underestimate capacity predictions for lightly shear reinforced concrete beams. The uneconomical trend of performance of EC2 VSIM at low levels of shear reinforcement can be ascribed to the neglect of concrete contribution to shear resistance by the shear procedure which is more significant in lightly shear reinforced beams. Towards developing a more accurate and adequate shear design procedure, this contribution presents a modification of the EC2 VSIM for beams with shear reinforcement. The modified VSIM procedure is a truss model with variable angle of inclination of the struts plus a concrete contribution. The concrete contribution term introduced is based on the proposed Compression Chord Capacity model developed by Cladera et al. (2016) and the concrete strut angle is based on the established Modified Compression Field Theory (Bentz et al, 2006). Database of experimental beams with shear reinforcement published by other authors are used to assess the performance of the modified EC2 VSIM procedure. The capacity predictions from the proposed procedure was found to be characterised by low bias and uncertainty as well as statistical independence with respect to the main parameters affecting shear capacity of reinforced concrete beams. Hence, predicting a more accurate and consistent capacity across the range of main shear parameters.

This work deals with the optimum design of variable angle-tow (VAT) composites in the theoretical framework of B-Spline surfaces. The design problem is formulated as a constrained optimisation problem in the context of the multi-scale two-level (MS2L) optimisation methodology. The proposed approach aims at optimising all parameters characterising the VAT laminate at each pertinent scale (mesoscopic and macroscopic ones). In particular, this study focuses on the first level of the MS2L optimisation strategy that aims at determining, at the VAT laminate macroscopic scale, the optimum distribution of the laminate mechanical properties over the structure. At this stage, the behaviour of the VAT composite is described by means of the polar formalism and the spatial distribution of the polar parameters is represented through a set of suitable B-Spline surfaces. The expression of the gradient of objective and constraint functions is determined in a closed form by exploiting the properties of the B-Spline surfaces. Moreover, the effect of the discrete variables tuning the shape of the B-Spline surfaces (mainly the number of control points) on the quality of the optimum solution is investigated. The effectiveness of the proposed approach is tested through some meaningful benchmarks taken from literature.

With the continuous development of the global economy and industry, and gradually expand the size of offshore oil exploration and transportation, the possibility of oil field leakage, damage of offshore tanker, oil leakage of the offshore ship and the oil spill is increasing continuously, and the harmfulness is increasing continuously. It has seriously polluted the Marine environment and destroyed the ecological balance, and seriously wasted the oil resources. Therefore, this paper developed a kind of offshore oil spill removal ship which can quickly, accurately, and effectively recover oil spill. This paper designs an offshore oil removal device with a variable Angle of attack. Through the use of Rhino and SolidWorks modeling software for the three-dimensional overall design. The variable Angle of attack offshore oil spill removal ship can be divided into seven major systems, which are the main hull of the variable angle of attack, the side hull, the oil suction, and deoiling rollers, the oil collecting groove and oil collecting chamber, the oil baffle, the steering platform, the communication equipment, the propulsion equipment, the main hull, and the external ship docking equipment. At the same time, the new type of offshore oil absorption material is installed on the double roller oil absorption mechanism, and each component system of the offshore oil removal ship is assembled. In this paper, the design of a variable Angle of attack offshore oil spill removal ship can provide a reference for the research and design of a new offshore oil spill treatment device.

Fixation of distal femoral fractures is often challenging due to the fracture configuration and often associated poor bone quality. Dual plating (lateral and medial) has become an acceptable option to provide improved stability, versus single plate fixation. Though there are several commercially available anatomically designed plates for the lateral femoral condyle, there is no anatomic plate available in UK specifically for medial fixation of distal femur fractures. Our aim is to determine the best suited pre-contoured plate for stabilising the Medical femoral condyle (MFC). Right femur sawbones was used to determine how well 18 different pre-contoured anatomical plates (Depuy Synthes, Leeds, UK) fit the medial femoral condyle. Some of these had variable angle (VA) option. Lift off, fit and notch penetration were assessed and recorded independently by 4 orthopaedic trauma surgeons. The number and distribution of screws in the MFC that each plate allowed was also determined. To do this the MFC was divided into quadrants: Proximal anterior (PA), distal anterior (DA), proximal posterior (PP) and distal posterior (DP). The ipsilateral anterolateral proximal tibial (VA and 4.5mm non-VA), PHILOS, posteromedial proximal tibial and ipsilateral lateral extra-articular distal humeral plate offered good sagittal fit, less than 2mm lift off at the condyles and no diaphyseal lift off. Plate positioning in the PA quadrant offered the best fit. The ipsilateral anterolateral proximal tibial plates (VA) and PHILOS allowed at least 4 screws to be placed in the PA and 2 in the PP quadrant with no notch penetration. The Tomofix provided good fit, but all 4 screws were in PA quadrant, with distal screws causing notch penetration. The non-VA and PHILOS plates did not offer the VA advantage. The ipsilateral anterolateral proximal tibial VA plates provided the best anatomical fit for the MFC with the greatest number of screws in the condylar quadrants with the option of variable angle screw placement.

Introduction This study examines the clinical, functional and radiological outcomes of distal radius fracture fixation with the Aptus® (Medartis, Pennsylvania) locking plate in order to determine its efficacy and to identify notable findings related to treatment variations. Method This is a retrospective bi-centre study collecting patient details from a District General Hospital and a Regional Hand Unit. We assessed 61 consecutive patients with distal radius fractures (AO grade A = 19, B = 9, C = 33) fixed using Aptus® plate with a minimum of six months follow-up. Outcome measures included the DASH score, wrist range of movement and grip strength, and complications. Radiographs were reviewed to assess restoration of anatomy and union. Results All but two fractures united within six weeks. Mean ranges of movement were only mildly restricted compared to the normal wrist (flexion/extension = 102°; radial/ulna deviation = 53°; pronation/supination = 169°). Mean postoperative grip strength was 23.8kg which was comparable to the contralateral side at 31.5kg. The mean DASH score was 18.2. Seven patients had screws misplaced outside the distal radius although three of these remained asymptomatic. Conclusions Variable-angle locking systems benefit from flexibility of implant positioning and may allow enhanced inter-fragmentary reduction for accurate fixation of intra-articular fractures.

Circumstellar discs may become warped or broken into distinct planes if there is a stellar or planetary companion with an orbit that is misaligned with respect to the disc. There is mounting observational evidence for protoplanetary discs with misaligned inner discs and warps that may be caused by such interactions with a previously undetected companion, giving us a tantalising indication of possible planets forming there. Hydrodynamical and radiative transfer models indicate that the temperature varies azimuthally in warped discs due to the variable angle at which the disc surface faces the star and this impacts the disc chemistry. We perform chemical modelling based on a hydrodynamical model of a protoplanetary disc with an embedded planet orbiting at a 12$^{\circ}$ inclination to the disc. Even for this small misalignment, abundances of species including CO and HCO$^+$ vary azimuthally and this results in detectable azimuthal variations in submillimetre line emission. Azimuthal variations in line emission may therefore indicate the presence of an unseen embedded companion. Nonaxisymmetric chemical abundances should be considered when interpreting molecular line maps of warped or shadowed protoplanetary discs., Accepted to MNRAS. 18 pages, 14 figures

The paper considers a three-stage technology for angular rolling of the pipe workpiece. This technology facilitates the expansion of the range of flange parts available by eliminating a number of drawbacks of the known methods of metal forming. In the presented paper, we analyze the results of numerical calculations and experiments, as well as the effective deformation values in blank material, using computer simulation in the DEFORM-3D software package. The results of the computer simulation were reached taking into account experimental studies of the rheological properties of copper alloy L68 in the form of a strain hardening curve using the Instron-8850 complex. The results of the ratio of basic geometric dimensions expanded the range of flange parts under investigation and allowed us to consider angular rolling technology with a variable angle of inclination of the rolling roll from a three-stage perspective, especially in small-scale production.

Extensor tendon ruptures caused by bicortical screws impingement following distal radius fracture fixation with volar plates are extensively reported in the literature. Thus, a biomechanical study comparing unicortical and bicortical fixations in intra-articular distal radius fracture models is critical in decision-making regarding distal radius fracture management. Forty-two synthetic radius models were fixed using a variable angle volar distal locking plate with seven screws. They were divided into 6 groups (n = 7): G1/G3/G4 unicortical fixation (75% of anteroposterior distal radius lenght); G2/G4/G6 bicortical fixation. Each group underwent a different mechanical test: axial compression (G1/G2), dorsal flexion (G3/G4), and volar flexion (G5/G6). The load application rate was 5 mm/min and 1000 cycles of 50 to 250 N at 1 Hz were performed between both static tests. Comparative results in the first static test, in the second static test, and in failure generally showed a very similar behavior. Models depicted similar behavior in the second static test when cyclic load was performed. Therefore, one can realize that stiffness differed during dorsal flexion only in the first static test. Maximum force to break the model in axial compression was greater in bicortical than in unicortical construct. Since biomechanical properties are similar, we recommend using unicortical distal locking screws in distal radius fracture fixation with volar plates to prevent extensor tendon ruptures.

Without extra dc-dc converters, variable angle phase shift control (VAPSC) strategy is commonly used in a wireless power transfer system (WPTS) to achieve the required output and ZVS operation of converters simultaneously. However, the power losses of the WPTS with VAPSC have not been analyzed when the WPTS operates in the optimal power angle range (OPAR). In this paper, the power losses of the SS-type WPTS have been analyzed in detail. Moreover, based on VAPSC, a double-loop control strategy (DLCS) with a dynamic efficiency optimization method is proposed. Finally, a 500-W WPTS prototype is built to verify the rationality of the proposed control strategy. It can achieve a very high overall transfer efficiency in the whole charging process and the maximum transfer efficiency can reach 95.2% with k = 0.2 under the rated transfer power.

Background Reduction loss is commonly seen even in the newly designed locking plate fixation for distal radius fractures. Our study purpose is to investigate the efficacy of the variable angle volar locking plate (VAVLP) in maintenance of fracture fixation. Methods A total of 37 patients of unilateral distal radius fractures receiving VAVLP fixation were included. Forearm radiographs immediately after surgery and those at 3 months were retrospectively reviewed for analysis of radiographic parameters including radial height (RH), ulnar variance (UV), radial inclination (RI), volar tilt (VT), tear drop angle (TDA), distal dorsal cortical distance (DDD) and Soong classification (SC). Results By comparing the 3-month measurement and normal data, the difference of RH/UV/TDA was significant (p-value < 0.001) while the difference of RI/VT was insignificant. However, there was no significant difference regarding those five parameters between postoperative and 3-month measurement. Linear regression on DDD exhibited positive dependence with p-value of 0.002 between postoperative and 3-month changes. Postoperative SC was grade 0 in 13 patients, grade 1 in 21, and grade 2 in 3. There were 7 of Gr 0 and 2 of Gr 1 making one grade up.Conclusion VAVLP fixation in distal radius fracture can maintain radiographic alignment without significant reduction loss for at least 3 months. Realignment within normal range was in RI and VT, but not in RH/UV/TDA.
