Coagulation/Fibrinolysis and Thrombosis in Coronavirus Disease 2019: A Review Based on Up-To-Date Knowledge

Introduction: Coronavirus disease (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that developed into an ongoing pandemic. The main pathology of COVID-19 is viral pneumonia, but thrombotic complications are frequently observed and are associated with its severity. Methods: We selected qualitatively and quantitatively reliable reports, which were related to thrombosis and were associated with COVID-19, using the Google Scholar and PubMed search engines. The features of abnormal coagulation/fibrinolysis and thrombosis were reviewed based on these reports. Results: Thrombosis accompanying COVID-19 can occur in veins, arteries, and capillaries. Macrothrombosis and microthrombosis can also occur. Furthermore, the patterns of disseminated intravascular coagulation that accompany COVID-19 can vary from the fibrinolysis-suppressing to the fibrinolysis-enhancing type. Discussion: Coagulation/fibrinolysis abnormalities in patients with COVID-19 should be investigated over time using many markers, including D-dimer levels. Based on the obtained results, prospective randomized clinical trials on antithrombotic drugs should be conducted to establish an effective treatment. Conclusion: Further elucidation of the characteristic pathology of coagulation/fibrinolysis and thrombosis in patients with COVID-19 is expected, which would lead to the development of appropriate treatments.

Temperature Effect on the Structural Design of a Mach 8 Vehicle

Hypersonic aircraft design is a pressing area of research. The motivation to create aircraft that can cross the globe in only a few hours is driving this forward but there are a number of challenges that need to be overcome. One of the principle challenges is the effect that temperature has on the structure. Temperature changes cause heating of the structure as well as changing the material properties of the affected structure. This has a compound effect in that the structures gets geometrically deformed, stiffness is reduced, and this will have an impact on the aerodynamic and structural performance of the vehicle. This article investigates the effect of two different structural concepts: a conventional rib-spar configuration and a pillow tank. A number of different structural options in terms of number of ribs / spars will be investigated. The structure will be optimised based on critical loading conditions. Results for various temperature distributions will be investigated, while looking at change on structural strength, in-flight static deformation and dynamic response. Keywords: Aeroelasticity, Hypersonics, Design.
Project Management Office Transformations: Direct and Moderating Effects that Enhance Performance and Maturity

This article aims at understanding organizational change through the study of project management office (PMO) transformations. This article suggests that performance resulting from a PMO transformation is moderated by the organizational context, change management, and by changes in coordination mechanisms—control or service orientation. This exploratory study adopted a quantitative methodology involving a sample of 184 PMO changes. It confirms the multifaceted nature of the context involved in a PMO transformation. External events play a key role in triggering change and improving performance. Key findings suggest that increasing the PMO's supportive role improves project performance, business performance, and project management maturity. Conversely, increasing the PMO's control role does not improve performance. This study's major contribution is to provide some empirical evidence concerning organizational change management.
General expressions for IM/DD dispersive analog optical links with external modulation or optical up-conversion in a Mach-Zehnder electrooptical modulator

A general derivation of the optical modulation process in a dual-drive Mach-Zehnder modulator (DD-MZM) is introduced. The expressions include all harmonics and are entirely general in terms of bias point. Chromatic dispersion is also included allowing the prediction of a number of important phenomena in photonic signal transmission. Examples of special cases of these general equations are then presented. Similar expressions are introduced for harmonic optical up-conversion through a photonic mixer based on a DD-MZM covering any bias point or phase shift between DD-MZM drives.
Statistical Process Control: A Guide for Implementation

Focuses on the Statistical Process Control (SPC) implementation phase in an effort to underline that SPC is not just control charts, and that many steps have to be accomplished before these charts are used. In addition, highlights the role of training and presents it as an ongoing process which involves everyone in the organization. These SPC implementation steps are not meant to be a checklist; they provide guidelines that can be modified in accordance with organizational‐specific requirements.
Retrospective Analysis of Adverse Events of Continuous Interscalene Block Administered Using the Catheter-Over-Needle Method.

Purpose Continuous interscalene block is widely used for pain management in shoulder surgery. However, continuous interscalene block using the catheter-through-needle method reportedly causes adverse events, such as pericatheter leakage of the local anesthetic, phrenic nerve paralysis, and hoarseness. Because we expected the catheter-over-needle method to reduce those adverse events, we analyzed cases in which continuous interscalene block was administered using the catheter-over-needle method to determine when and what adverse events occurred.Methods We retrospectively reviewed anesthesia and medical records of adult patients who inserted the catheter with a continuous interscalene block administered with the catheter-over-needle method at our hospital from July 2015 to July 2017.Results During the surveillance period, 122 adult patients inserted the catheter with a continuous interscalene block administered using the catheter-over-needle method. We found no case of pericatheter local anesthetic leakage. Other adverse events—dyspnea, hoarseness, insufficient anesthetic effect, dizziness, cough reflex during drinking, or ptosis—were observed in 42 cases (34.4%). Most of the adverse events occurred on postoperative day 2. The median time between surgery and onset of the adverse event was 28.5 hours.Conclusions The catheter-over-needle method may prevent the pericatheter leakage of the local anesthetic. However, the number of other adverse events that occurred with continuous interscalene block was remarkable. During continuous interscalene block, patients must be observed carefully for adverse events, especially on postoperative day 2.
Resistive Susceptor Design for Uniform Heating during Induction Bonding of Composites

A novel susceptor concept for metal mesh susceptors, designed to achieve uniform in-plane temperatures during induction heating, is documented. The process involves redirecting eddy current flow patterns in the resistive mesh susceptor by specifically designed cut patterns in the mesh. A theoretical model was developed to predict heat generation in metal mesh susceptors with any prescribed network pattern. Initial results for meshes with cut patterns show significant changes in heating compared to an uncut mesh. Cut patterns can be optimized to reduce temperature gradients in the susceptor to within the processing window of the composite. Experimental results are presented for qualitative comparisons.
Direct comparison of electrical performance of 0.1-/spl mu/m pMOSFETs doped by plasma doping or low energy ion implantation

The fabrication of ultra-shallow junctions (USJ) is becoming one of the most challenging tasks for advanced CMOS technology. We experimentally show the limits of the standard ion implantation technique. Then, we demonstrate the benefit induced by the use of the low biased PLAsma Doping (PLAD) processes to fabricate USJ. Next, we have fabricated deep sub-micrometer pMOSFETs. The measured electrical results show that the basic device performance is improved when the source/drain extensions are plasma doped instead of the standard BF/sub 2//sup +/ implantation. We attribute this improvement to a better control of the lateral spread of the extensions under the gate. This characteristic is directly correlated to the strong reduction of the junction depth when the PLAD technique is used.

Kertas kerja ini menerangkan aplikasi kaedah permodelan (ARIMA) bagi mewakili perilaku penggunaan air di kampus Universiti Teknologi Malaysia. Menggunakan fungsi–fungsi ACF, PACF dan AIC, siri masa penggunaan air bulanan di kampus UTM boleh dinyatakan dalam model ARIMA (2,0,0). Anggaran parameter model o1 dan o2 ialah 0.2747 dan 0.4194. Keadaan tersebut menggambarkan bahawa penggunaan air pada bulan semasa tidak semestinya dipengaruhi dengan tepat oleh kadar penggunaan air pada bulan sebelumnya. Analisis juga menunjukkan model ARIMA (2,0,0) boleh diguna sebagai model ramalan guna air di kampus universiti. Kata kunci: Guna air, kampus universiti, siri masa, model ARIMA The paper describes the application of autoregressive integrated moving average (ARIMA) model to represent water use behaviour at Universiti Teknologi Malaysia (UTM) campus. Using autocorrelation function (ACF), partial autocorrelation function (PACF), and Akaike’s Information Criterion (AIC), monthly campus water use series can be best presented using ARIMA (2,0,0) model. The estimated parameter of the model o1 and o2 are 0.2747 and 0.4194 respectively. This implies that water consumption in UTM campus at the present month is not necessarily influenced by water consumption of immediate previous month. Analysis shows that ARIMA (2,0,0) model provides a reasonable forecasting tool for campus water use. Key words: Water use, university campus, time series, ARIMA model
Optimal Weapon Target Assignment Based on an Geometric Approach

Abstract In this paper, dynamic weapon target assignment is proposed for area air defence. The focus of this study is to optimally protect a convoy of friendly assets from oncoming targets whose manoeuvres are hard to be predicted. The earliest geometry provides a boundary of the intercept region without prediction of target manoeuvre. If any of friendly asset is located in this region, this asset might be destroyed by the targets. Therefore, the safety margin can be defined as the minimum distance between the earliest geometry and friendly asset. This safety margin naturally copes with the unpredictability of the target manoeuvre. In many-on-many engagement scenarios, the safety margin changes in accordance with allocation policies and it is closely related to the performance of the area air defence system. Thus, we formulate an optimal assignment problem using the safety margin and introduce an optimisation approach. The proposed optimisation method integrates the evolutionary game and particle swarm optimisation in order to improve the optimality as well as to reduce computational load. The performance of the proposed scheme for weapon target assignment is evaluated by non-linear simulations.
Effects of information access cost, confidence judgment and overconfidence bias on information retrieval strategy and task performance

Information access cost has been reported to be one determinant of one’s information retrieval strategy. However, the “expected gain” of an information retrieval strategy has not received much attention. The present study aimed to examine the effects of confidence judgment and overconfidence bias, besides the information access cost, on the choice of information retrieval strategy and task performance. The results showed that both information access cost and confidence judgment of memory accuracy affected information access attempts, and overconfidence bias harmed information retrieval performance.
Constructability improvement during field operations

Constructability issues still exist during field operations and once in the field, constructors can still reap constructability benefits from their actions alone. The objective of this paper is to explore the ways in which construction knowledge and experience can enhance constructability during field operations. While previous constructability research efforts have been primarily directed toward owners and designers, this research is primarily directed toward constructor organizations. The employed research method was an iterative process of issue identification, literature search, site interviews, and analysis. Ultimately, a single prime concept for field operations constructability was concluded: Constructability is enhanced when innovative construction methods are utilized. Innovative construction methods may involve innovations related to sequencing of field tasks, temporary construction materials/systems, hand tools, construction equipment, constructor‐optional preassembly, temporary facilities dire.
Manufacturing: A Strategic Opportunity for Engineering Education

This paper examines the importance of the manufacturing enterprise and the need for manufacturing education. The objective is to present a case for the expansion of manufacturing‐related education as a strategic opportunity for engineering education. A brief history of engineering education is presented, as well as an exploration of the current ABET criteria for various engineering disciplines. Approaches for achieving manufacturing‐related education are presented noting that Mechanical Engineering and Industrial Engineering are often most closely associated with manufacturing. Surveys of industry reveal the need for manufacturing education and identify preferred approaches. If manufacturing is to be included as part of a mechanical engineering program, there are a number of possible approaches. Of all the new technologies that will impact engineering education, none is larger than the Internet. The number of manufacturing educational programs in the United States is growing substantially. New manufacturing programs are encouraged along with review of educational content in traditional engineering disciplines‐especially the related discipline of mechanical engineering. Analysis leads us to believe that manufacturing represents a strategic direction and opportunity for engineering education to pursue.
Economic quality control of manufactured product

That we cannot make all pieces of a given kind of product identically alike is accepted as a general truth. It follows that the qualities of pieces of the same kind of product differ among themselves, or, in other words, the quality of product must be expected to vary. The causes of this variability are, in general, unknown. The present paper presents a scientific basis for determining when we have gone as far as it is economically feasible to go in eliminating these unknown or chance causes of variability in the quality of a product. When this state has been reached, the product is said to be controlled because it is then possible to set up limits within which the quality may be expected to remain in the future. By securing control, we attain the five economic advantages discussed in Part III.

BIO-AGRICULTURE AND ITS EFFECT ON THE PRODUCTIVITY AND QUALITY OF PEANUTS (ARACHIS HYPOGAEA) UNDER NORTH SINAI CONDITION - EGYPT.

A field experiment was conducted at Baloza Experimental Station of the Desert Research Center (DRC) in North Sinai Egypt. The GIS indices of this location are N3101-43.0296E 32035-28.0431) in two successive summer seasons of 2015 and 2016. The most prominent objectives of the current work can be portrayed in recycling olive oil extraction waste, verifying the role played by bio-fertilizers in utilizing the manufactured compost, diminishing the pollution brought about by mineral fertilizers, testing the nutritional function of Biomagic to peanut plants, and figuring out the best combination treatment among all these production tools that give the highest possible peanut seed content at the best possible quality under the conditions of North Sinai of Egypt. The applied treatments involved applying olive compost vs. no application, spraying Biomagic nutrient solution vs. no spraying, inoculating the seeds with Rhizobium (the control treatment) vs. inoculating the seeds with Azotobacter and phosphorous dissolving bacteria both applied separately or together in a mixed inoculation. These treatments were arranged in a factorial experiment in three randomized complete blocks. Mean values were verified from each other using Dunkan least significant range (LSR) and denoted by alphabetical letters. In that, any two mean values sharing an alphabet letter are not significantly different. The superior combination treatment is to be composed of applying compost x canopy spraying x biofertilizers, shows that the best combination treatment was composed from applying compost + spraying plants’ canopy with Biomagic x inoculating the seeds with a mixture of Azotobacter and PDB in both years of study. This treatment could significantly proliferate better growth conditions in the rhizosphere that nourished the most vigorous microbiological growth. It could lead to better peanut plants vegetative growth. It could also lead to the best significant peanut seed content with best quality. Detailed effects of all applied factors can be found in the research. Egypt. J. of Appl. Sci., 36 (3) 2021 132-147
A new alternative for corneal endothelial regeneration using autologous dental pulp stem cells

Background Failure of the corneal endothelium cell (CEC) monolayer is the main cause leading to corneal transplantation. Autologous cell-based therapies are required to reconstruct in vitro the cell monolayer. For this purpose, we propose the use of dental pulp stem cells isolated from the third molars to form CEC monolayer. We hypothesize that by using dental pulp stem cells (DPSC) that share an embryological origin with CEC, as they both arise from the neural crest, may allow a direct differentiation process avoiding the use of reprogramming techniques, such as induced pluripotent stem cells (iPSC). Methods In this work, we report a two-step differentiation protocol, where dental pulp stem cells are derived into neural crest stem cells and, then, into CEC. Results Initially, we compared the efficiency of direct differentiation of DPSC with the differentiation of iPSC to express NCSC related genes in adhesion culture, showing significantly higher levels of early stage marker AP2 for the DPSC compared to iPSC. To provide better environment for NCSC gene expression, suspension method was performed, which induced the formation of neurospheres. The results showed neurosphere formation after few days, obtaining the peak of NCSC marker expression after 4 days, showing overexpression of AP2, p75 and CHD7 markers, confirming the formation of NCSC like cells. Furthermore, pluripotent markers Oct4, Nanog and Sox2 were as well upregulated in suspension culture. Neurospheres were then directly cultured in CEC conditioned medium for the second differentiation, showing the conversion of DPSC into polygonal like cells expressing higher levels of ZO-1, ATP1A1, COL4A2 and COL8A1 markers, providing proof of the successful conversion into CEC. Conclusions Therefore, our findings demonstrate that patient-derived dental pulp stem cells represent an autologous cell source for corneal endothelial regeneration that avoids actual transplantation limitations as well as reprogramming techniques.
Dynamic Behavior of the Palazzo Lombardia Tower: Comparison of Numerical Models and Experimental Results

AbstractThe Palazzo Lombardia Tower, located at the heart of the city of Milan, Italy, recently was completed. At 161.30 m high, the new building is currently the tallest in Italy and one of the most prominent features of the city skyline for many years to come. Given the strategic importance and the strong impact of the new building, it was decided to perform a series of dynamic excitation tests, with special emphasis on the Tower. Thus, it was possible to estimate its basic modal features and then compare them to the numerical simulation predictions provided by the same finite-element (FE) numerical analysis used for design. This offered the chance to start an important and interesting model-updating procedure, taking advantage of both the actual material properties measured during the construction phase and dynamic measurements, the latter having added significant insight to the structural behavior. The mechanical engineering department of the Polytechnic University of Milan was in charge of the design.
The Mechanical Property of Magnetorheological Fluid Under Compression, Elongation, and Shearing

The mechanical properties of a MR fluid in compression, elongation, and shearing have been studied in the magnetic field which is generated by a coil carrying different magnitudes of DC electrical current. Test equipment is designed to perform this operation. The compressing tests showed that the MR fluid is quite stiff at small compressive strains being lower than 0.13. The compressive stress and modulus increase quickly when the compressive strain is higher than 0.2. The tensile yield stress of MR fluids represents the effect of the interaction force between the polarized particles and the direction of the applied magnetic field. The shear yield stress represents the effect of the interaction force with the shear direction (perpendicular to the direction of the magnetic field). The relationship between tensile yield stress and shear yield stress verifies the credibility of the calculation model employing a yield angle shaped between particles. A shear yield angle is found to be between about 13.8° and 1.
