The Effect of Local Tranexamic Acid Administration on Blood Loss and Transfusion in Total Knee Arthroplasty: A Retrospective Study

Objectives The standard surgical method for primary gonarthrosis in advanced stages is total knee arthroplasty (TKA), despite the risk of bleeding that requires transfusion. Blood transfusions are potentially dangerous. The aim of this study was to determine whether there is a statistical difference in the amount of bleeding and the need for transfusion between patients who received and did not receive perioperative local tranexamic acid in TKA. Methods The hospital data system was used to access the data of patients who underwent TKA in our clinic between January 2015 and January 2022 with a diagnosis of gonarthrosis. Patients who underwent TKA and had gonarthrosis as the primary diagnosis were included in the study. They were separated into two groups: A control group (Group C) and a group that received perioperative local tranexamic acid (Group LTXA). The amount of bleeding was compared by taking into account patients’ hemogram follow-ups, the amount of blood from their drains, and their transfusion needs during the postoperative period. Results The findings demonstrated that TKA patients who received local tranexamic acid administration experienced a significant decrease in perioperative blood loss and needed lesser transfusions. Conclusion The findings of our investigation are consistent with other studies and are in favor of the usage of TXA in TKA. To validate our findings and establish the ideal TXA dosage and administration method in TKA, additional research is required.

Flight Performance Evaluation of the Flying-V

This study evaluates the flight performance of a Flying-V aircraft designed for transonic passenger transport. The Flying-V is a disruptive aircraft configuration that has shown to possess promising aerodynamic performance during preliminary design. It is compared to a competitor aircraft reminiscent of the Airbus A350-1000, for the same thrust-to-weight ratio and a similar number of passengers. The most common performance metrics for the take-off, landing, climbing and cruise phases have been assessed using a modular flight mechanics model. Take-off and landing performance are evaluated through flight simulation using a simple Euler method, while climb and cruise performance are evaluated in trimmed, steady-state conditions. Only instantaneous performance is available for the latter two phases. The Flying-V outperforms its competitor for basically all investigated metrics. Take-off length is shorter, mainly due to a larger tail strike attitude that reduces the minimum unstick speed. Service and absolute ceiling are higher, and its superior lift-over-drag ratio results in a 21% increase in the cruise range parameter. Landing field lengths are similar for both aircraft, but the Flying-V has a significantly larger pitch angle during approach. This causes longer de-rotation length, and a large obscured segment of the pilot’s vision which could be problematic during operations.
Finite-deformation second-order micromorphic theory and its relations to strain and stress gradient models

Germain’s general micromorphic theory of order n is extended to fully non-symmetric higher-order tensor degrees of freedom. An interpretation of the microdeformation kinematic variables as relaxed higher-order gradients of the displacement field is proposed. Dynamical balance laws and hyperelastic constitutive equations are derived within the finite deformation framework. Internal constraints are enforced to recover strain gradient theories of grade n . An extension to finite deformations of a recently developed stress gradient continuum theory is then presented, together with its relation to the second-order micromorphic model. The linearization of the combination of stress and strain gradient models is then shown to deliver formulations related to Eringen’s and Aifantis’s well-known gradient models involving the Laplacians of stress and strain tensors. Finally, the structures of the dynamical equations are given for strain and stress gradient media, showing fundamental differences in the dynamical behaviour of these two classes of generalized continua.
Egg weight estimation and the effect of age and plumage colors on some egg quality traits in Japanese quails (Coturnix coturnix japonica)

The aim of this study was to investigate the effect of different age and plumage color on the egg quality traits and cholesterol levels, in addition to which traits can be used for egg weight prediction in Japanese quails. The eggs obtained from 23-week-old original plumage colored Japanese and Jumbo quails, and 39-week-old Jumbo quails; 40, 40, and 20 eggs were used respectively as the research material. The eggs obtained from 23-week-old original plumage colored Japanese and Jumbo quails, and 39-week-old Jumbo quails; 40, 40, and 20 eggs were used respectively as the research material. In terms of plumage color difference, when Japanese quails were compared to Jumbo quails; yolk weight, yolk height, yolk diameter were higher, and likewise the cholesterol level was lower (P<0.01). The lowest cholesterol content was found in eggs from 23-week-old Japanese quail (P<0.01). Egg width, shape index, yolk height, and shell weight in group 1; albumen weight, yolk diameter, and egg volume in group 2; egg volume and egg length data in group 3 have determined the best fit for estimation of the egg weight. As a result, the plumage color is a factor that affected the egg quality traits and cholesterol level in quails. Furthermore, some egg quality traits may be used to establish the equations for estimation of the egg weight. Keywords: Age; Egg quality traits; Egg weight estimation; Plumage color; Quail
Does Debt Policy for Capital Structure Matter to Saudi Listed Firms?

The research investigates mainly the relevance of capital structure to Saudi listed firms by assuming the endogeneity of debt, ownership structure, and firm value. The empirical results show strong evidence of no relationship between leverage and firm value, hence the irrelevance of capital structure for Saudi listed firms operating in the no tax and no tax benefit regime. Additionally, the results show the moderation effect of equity finance and family control in the relationship between debt and firm value. Moreover, it is indicative that debt is endogenous and that there is a nonlinear (cubic) relationship between debt and firm value. Finally, we find that there is nonlinear relationship (cubic) relationship between executive ownership and firm value.
Measurements of baryon form factors at BESIII

The momentum transfer dependence of the electromagnetic form factors is an important probe of the structure of hadrons at different scales. Using data samples collected with the BESIII detector at the BEPCII collider, we study the process of e+e- → pp̄ at 12 c.m. energies from 2232.4 to 3671.0 MeV. The Born cross section at these energy points are measured as well as the corresponding effective electromagnetic form factors. Furthermore, the ratio of electric to magnetic form factors, |GE/GM| and |GM| are measured at the c.m. energies where the data samples are the largest. We also report preliminary results of e+e- → ˄˄̅, which is analysed with the same method. Moreover, future prospects of the measurement of baryon electromagnetic form factors from a unique high luminosity data scan by BESIII, are given.
Uplifted marine terraces by active coastal tectonic deformation along the east of Algiers: implications for African and European plate convergence and sea-level curves

Marine terraces are geological features composed of elevated, flat surfaces and steep slopes. The evolution of these terraces is largely influenced by active coastal tectonic deformation. This study investigates the uplift of marine terraces along the east coast of Algiers and its implications for the African and European plate convergence and sea-level curves. The objective of studying marine terraces in the Zemmouri area is to gain a deeper understanding of the evolution of the Earth's coastlines and how they have been shaped over time by natural processes such as sea level changes, tectonic activity, geomorphic parameters, and erosion. Marine terraces provide valuable information about the history of sea level changes and the rate of tectonic uplift or subsidence of the coastal areas. Secondary data sources, including qualitative information and high-resolution satellite imagery (SRTM 30 m and ALOS 12.5 m), were used to analyze the impact of sea level on marine terraces. Fieldwork using GPS and altimeter measurements at the site of the Mw=6.8 Zemmouri earthquake that occurred on May 21, 2003, revealed the presence of two well-preserved marine terraces, which serve as important markers for measuring the long-term fault slip rate. The analysis highlights the significance of active coastal tectonic deformation in shaping the coastlines. This research offers new insights into the ongoing processes of plate convergence and sea level change along the east coast of Algiers, contributing to our overall comprehension of coastal evolution and the potential for seismic hazards in the region.
Relationship between crystal defects and leakage current in β-Ga2O3 Schottky barrier diodes

We fabricated Schottky barrier diodes (SBDs) on the entire surface of a β-Ga2O3 single crystal, and investigated the leakage current in both forward and reverse directions. Subsequently, we investigated the distribution of dislocation and void etch pits on the entire surface. The dislocation etch pit density on the surface ranged from <1 × 103 to 6 × 104, and its average was 1.1 × 104 cm−2. The void etch pit density on the surface ranged from <5 × 102 to 7 × 103, and its average was 6 × 103 cm−2. From a comparison between the SBD leakage current and the dislocation and void etch pit densities, we found that dislocations are closely related to the SBD reverse leakage current, and that not all voids produce the leakage current.
Maths lecturers in denial about their own maths practice? A case of teaching matrix operations to undergraduate students

This case study provides evidence of an apparent disparity in the way that certain mathematics topics are taught compared to the way that they are used in professional practice. In particular, we focus on the topic of matrices by comparing sources from published research articles against typical undergraduate textbooks and lecture notes. Our results show that the most important operation when using matrices in research is that of matrix multiplication, with 33 of the 40 publications which we surveyed utilising this as the most prominent operation and the remainder of the publications instead opting not to use matrix multiplication at all rather than offering weighting to alternative operations. This is in contrast to the way in which matrices are taught, with very few of these teaching sources highlighting that matrix multiplication is the most important operation for mathematicians. We discuss the implications of this discrepancy and offer an insight as to why it can be beneficial to consider the professional uses of such topics when teaching mathematics to undergraduate students.
DESCRIPTION OF THE 3D MORPHOLOGY OF GRAIN BOUNDARIES IN ALUMINUM ALLOYS USING TESSELLATION MODELS GENERATED BY ELLIPSOIDS

Parametric tessellation models are often used to approximate complex grain morphologies of polycrystalline microstructures. A big advantage of such models is the substantial reduction in disk space required to store large, three-dimensional data sets, especially when compared with voxel-based alternatives. By selection of an appropriate tessellation model, a reasonably small loss of information on the real grain shapes can usually be achieved. Special attention has recently been devoted to models based on ellipsoidal approximations fitted to each grain. Faces of these tessellations are portions of quadric surfaces whose parameters can be derived easily. In this paper, we deal with geometric features of the structure, notably curvatures and dihedral angles, which are closely related to the kinetics of grain growth. These characteristics are computed for ellipsoidbased tessellations fitted to two different aluminum alloys with nominal composition Al-3 wt% Mg-0.2 wt% Sc and Al-1 wt% Mg. The results are then compared with estimations based on meshed empirical data. We observe that the model offers more consistent estimations of grain shape characteristics than do the meshed empirical data. Precise description of grain boundaries by the model is also promising with respect to possible applications of these tessellations in stochastic space-time modeling of grain growth.
Verification of 24-h Quantitative Precipitation Forecasts over the Pacific Northwest from a High-Resolution Ensemble Kalman Filter System

AbstractEnvironment and Climate Change Canada (ECCC) has recently developed an experimental high-resolution EnKF (HREnKF) regional ensemble prediction system, which it tested over the Pacific Northwest of North America for the first half of February 2011. The HREnKF has 2.5-km horizontal grid spacing and assimilates surface and upper-air observations every hour. To determine the benefits of the HREnKF over less expensive alternatives, its 24-h quantitative precipitation forecasts are compared with those from a lower-resolution (15 km) regional ensemble Kalman filter (REnKF) system and to ensembles directly downscaled from the REnKF using the same grid as the HREnKF but with no additional data assimilation (DS). The forecasts are verified against rain gauge observations and gridded precipitation analyses, the latter of which are characterized by uncertainties of comparable magnitude to the model forecast errors. Nonetheless, both deterministic and probabilistic verification indicates robust improvements in.

The Cuckoo Optimization Algorithm Enhanced Visualization of Morphological Features of Diabetic Retinopathy

This research compares strategies for identifying diabetic retinopathy (DR) using fundus image and discusses the efficiency of various image pre-processing techniques to enhance the quality of fundus images. Fundus images in medical image processing often suffer from non-uniform lighting, low contrast, and noise issues, which necessitate image pre-processing to enhance their quality. The study evaluates the effectiveness of several optimization techniques in selecting the best technique for identifying DR. One of the image pre-processing techniques compared in the study involves comparing negative images, dark contrast stretch, light contrast stretch, and partial contrast stretch, which are then evaluated using standard performance metrics such as NIQE, PNSR, MSE, and entropy. The results are further optimized using the Cuckoo Search Algorithm. The proposed technique produces better image quality improvements in several performance metrics, such as MSE, NIQE, PSNR, and entropy. Bright Contrast Stretch outperforms other techniques in NIQE Mean 5.2850, Entropy 5.0193, NIQE Standard deviation 0.2261, and Entropy 0.2612.
Effect of Clay Brick Waste Powder on the Fresh and Hardened Properties of Self-Compacting Concrete: State-of-the-Art and Life Cycle Assessment

Sustainability and reducing environmental damage caused by CO2 emissions have become issues of interest to researchers in the construction sector around the world. Reducing the cement content in concrete by partially substituting it with by-products or waste falls within this field as the cement industry is responsible for 7% of global CO2 emissions. On the other hand, self-compacting concrete (SCC) is one of the special types of concrete that contains a large amount of powder (most of which is cement) to ensure its flow under the influence of its weight without separating its components. Therefore, to produce eco-friendly SCC, many researchers have replaced part of the cement with clay brick waste powder (CBWP) since brick units are among the most widely used building materials after concrete. Accordingly, this study aims to review previous research that included using CBWP in SCC. The effect of these wastes on the fresh, mechanical, durability and microstructural properties of cement was reviewed. Additionally, a comparison between the environmental impacts of SCCs with different CBWP contents has been conducted using the life cycle assessment (LCA) approach. It was found that the highest value of CBWP that can be used without negatively affecting the different properties of concrete is 10% by weight of cement. Moreover, regarding environmental impact, using CBWP as a substitute for cement reduces environmental damage, and the lowest environmental impact that can be achieved per strength unit (MPa) is 37.5%.
Retrieval process in free recall creates errors in short term memory but not in long term memory

An analysis of free recall errors shows that the free recall retrieval process in short term memory is accompanied by a linear rise in errors, without discontinuities, invalidating short term memory models in which stores or states are sequentially emptied. The frequency of errors increases at roughly 1% per second and exponentially if the items to be recalled are strongly related. This leads to a “Heisenberg uncertainty principle” situation: the more items recalled, the less accurate is the recall of those items. The error probability does not reach a plateau, is independent of time passing without a retrieval process being engaged, suggesting that the retrieval process itself introduces errors in short term memory. In contrast, in long term memory the error probability remains constant, indicative of a single store without retrieval induced errors. Error terminated short term memory free recall distributions are the same as distributions terminated by correct items.
Impact of The Covid 19 Pandemic: Is There Overreaction in LQ 45 Stock?

The Covid-19 pandemic has had an impact on various aspects of life, including the capital market which has caused a negative response on most stock exchanges around the world, including the Indonesia Stock Exchange. The Effecieny Market Hypothesis (EMH) explains that the price of a stock will always be reflected from the information available in the market or investors tend to be rational. However, dramatic events such as COVID-19 allow investors to overreact. The results showed that there was an overreaction in both winner and loser stocks in the LQ 45 group on the IDX in 3 months of observation since covid was announced as a pandemic. This overreaction is then followed by a price reversal even though it has not given a significant return after t+13 for both winner and losser stocks. The speed of price recovery (magnitude effect) after the price reversal on the loser stock is higher (faster) than the winner stock. The speed of this price recovery is significantly affected by the company's capital structure and share ownership of individual investors (local and foreign).
