Evaluation of Universities’ Distance Education by Students and Academicians in the Covid-19 (Coronavirus) Period: A Qualitative Research

The aim of the study is to evaluate the perspectives of students and academicians about distance education implemented by universities in the epidemic period and to determine the advantages and disadvantages of distance education to get an overall perspective. In the study, the data were obtained as a result of in-depth interviews with 12 students and 13 academicians. MAXQDA analysis program was used to analyze the data. The coded data were themed and analyzed. As a result of the analysis, concept maps were created and the analysis process was completed with interpretation. Conclusion of this study, the advantages and disadvantages of distance education applied by universities during the coronavirus period were evaluated. Recording the classes within the scope of distance education has given students the opportunity to review the classes. In this process, it is seen that education/training activities continue without any limitations on time and place. With distance education, it became possible to teach more than one class simultaneously. In this way, it became possible to reach more students in a shorter time. However, it has been found that the level of interaction between the academician and the student decreases in the distance education classes. As such, a decrease in motivation has been detected. Due to the COVID-19 pandemic, a rapid transition to distance education was made, and this rapid transition caused infrastructure and system problems. On the other hand, it is understood that a sound measurement and evaluation cannot be made in the exams applied in the distance education process.
Role of a Dual Glucose-Dependent Insulinotropic Peptide (GIP)/Glucagon-like Peptide-1 Receptor Agonist (Twincretin) in Glycemic Control: From Pathophysiology to Treatment

Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are two gut hormones, defined incretins, responsible for the amplification of insulin secretion after oral glucose intake. Unlike GLP-1, GIP has little acute effect on insulin secretion and no effect on food intake; instead it seems that the GIP may be an obesity-promoting hormone. In patients with type2 diabetes mellitus (T2DM) some studies found a downregulation of GIP receptors on pancreatic β cells caused by hyperglycemic state, but the glucagonotropic effect persisted. Agonists of the receptor for the GLP-1 have proven successful for the treatment of diabetes, since they reduce the risk for cardiovascular and renal events, but the possible application of GIP as therapy for T2DM is discussed. Moreover, the latest evidence showed a synergetic effect when GIP was combined with GLP-1 in monomolecular co-agonists. In fact, compared with the separate infusion of each hormone, the combination increased both insulin response and glucagonostatic response. In accordance with theseconsiderations, a dual GIP/GLP-1receptor agonist, i.e., Tirzepatide, known as a “twincretin” had been developed. In the pre-clinical trials, as well as Phase 1–3 clinical trials, Tirzepatideshowedpotent glucose lowering and weight loss effects within an acceptable safety.
Circularly polarised dielectric resonator antenna

A circularly polarised dielectric resonator antenna is reported. The circular polarisation is obtained by exciting the two orthogonal HE/sub 11 delta / modes of a cylindrical ring dielectric resonator in phase-quadrature. Measured results show that the antenna has an axial ratio of less than 3 dB over a beam width of 100 degrees with a minimum value of approximately 0.5 dB in this range. >
Intravenous Dexmedetomidine as an Adjunct to Neuraxial Anesthesia in Cesarean Delivery: A Retrospective Chart Review

Background Dexmedetomidine is a selective α-2 agonist commonly used for sedation that has been used in obstetric anesthesia for multimodal labor analgesia, postcesarean delivery analgesia, and perioperative shivering. This study evaluated the role of intravenous dexmedetomidine to provide rescue analgesia and/or sedation during cesarean delivery under neuraxial anesthesia. Methods We conducted a single-center, retrospective cohort study of all parturients undergoing cesarean delivery under neuraxial anesthesia between December 1, 2018, and November 30, 2019, who required supplemental analgesia during the procedure. Patients were divided into two groups: patients who received intravenous dexmedetomidine (Dexmed group) and patients who received adjunct medications such as fentanyl, midazolam, ketamine, and nitrous oxide (Standard group). Primary outcome was incidence of conversion to general anesthesia. Results During the study period, 107 patients received adjunct medications. There was no difference in conversion to general anesthesia between the Dexmed group and the Standard group (6% (4/62) vs. 9% (4/45); p=0.718). In the Dexmed group, the mean dexmedetomidine dose received was 37 μg (range 10 to 140 μg). While the use of inotropic/vasopressor medications was common and similar in both groups, there was an increase in the incidence of bradycardia (Dexmed 15% vs. Standard 2%; p=0.042) but not hypotension (Dexmed 24% vs. Standard 24%; p=1.00) in the Dexmed group. Conclusion In patients who required supplemental analgesia for cesarean delivery, those who received dexmedetomidine versus other medications had a similar rate of conversion to general anesthesia, a statistically significant increase in bradycardia, but no difference in the incidence of hypotension.
A Novel Method For The Fibre-Based Conductive Ring Spun Yarn Production

To take the advantages of spun yarns such as porosity, softness, bending as well as usability as yarn/fabric forms, in this study, it was worked on an alternative conductive yarn production method. Different from other methods such as coating, core-spun, blending, a conductive nanosuspension was applied to viscose, cotton and polyester open fibre bundles with different feeding amounts during the ring spinning with a specially developed apparatus. Reduced graphene oxide (rGO) was used to impart conductivity. Different from literature, rGO was synthesized with a single step process instead of two-step processes to ensure simple, easy-to-apply process and industrial applicability. Following to yarn production, winding, knitting and washing processes were realized to evaluate the changes in yarn conductivity and the usability of the yarns in the post-spinning processes. In addition to tensile properties of the yarns and air permeability of the fabrics, electrical resistance and environmental impact of the method was compared with immersion&drying process. The results indicated that alternative method allows the production of conductive (lower resistance than 100 kΩ) but also stronger, flexible, washable and breathable electronic textile products with an environmentally friendly process. There has been no effort, as yet, to get conductivity in this manner. Therefore, the developed method can be considered to be a new application in the functional yarn production field. The produced conductive yarns can be converted into fabric form by weaving, knitting and embroidery. Therefore, they can also be seen as an ideal as the platforms for future wearable electronics.
Dynamic Vehicle Dispatching at a Transfer Station in Public Transportation System

Dynamic vehicle dispatching at the transfer station can improve the transit service quality by optimizing the transfer coordination of routes. In this paper, a dynamic vehicle dispatching model is proposed that aims to minimize the total waiting time of passengers at the transfer station and the downstream stops. A prediction model based on support vector machines (SVM) is also developed to forecast the arrival time of the next vehicles at the transfer station. To reduce the disconnected cases between the transfer routes, an SVM-based model is introduced to forecast the elastic time for the estimated arrival time at the transfer station. According to the estimated arrival time and elastic time, vehicles are dispatched in a dynamic way to reduce the total waiting time of passengers. The dynamic vehicle dispatching approach at the transfer station is examined with the data of three transfer routes in the city of Dalian, China. Results show that the approach proposed in this paper can reduce the total waiting time of passengers at the transfer station and the downstream stops.
Did temporary protection induce technology adoption? A study of the US motorcycle industry

While under the umbrella of temporary protection from 1983 to 1987, Harley-Davidson (Harley), the sole US motorcycle manufacturer, bridged the technology gap with foreign rivals by successfully introducing a new engine, called the Evolution. With the diffusion of this engine across its model range, Harley steadily increased its sales from a low level at the beginning of the policy intervention. This paper assesses the causal relationship between temporary protection policy and technology adoption in the US motorcycle industry. Based on a structural econometric models of multiproduct oligopoly, this paper first shows that technology adoption well explains Harley’s sales increase during the protection; in the absence of technology adoption, Harley’s sales would not have turned around but continued to decrease. I then model Harley’s adoption of Evolution engine taking the effect of learningby-doing into account. Simulation results reveal a strong learning effect and the acceleration of the timing of adoption induced by the protection. However, the results also show that Harley would have successfully implemented the adoption of the new engine across its model range in the absence of the protection and thereby achieved the sales increase.
Effects of Organic Mulches on the Soil Temperature, Humidity and CO2 Emissions

A large portion of the world wine production is located in regions suffering - or expected to suffer - from desertification. These agricultural soils, in addition to being highly unstructured, have very low levels of organic matter (<1%). This is aggravated by an abusive tillage of the plots, which implies that the maintenance of these soils depends entirely on the addition of chemical products such as fertilizers and herbicides. This situation, in turn, leads to physiological imbalances in the vine that result in deficiencies in the quality of the grape. well as their this practice. The effectiveness of different organic mulching materials applied within the row of a vineyard was evaluated in a Tempranillo vineyard located in La Rioja (Spain). Organic mulches (straw mulch, SM; grapevine pruning debris, GPD and spent mushroom compost, SMC) were compared with two traditional bare soil management techniques (one based on the use of herbicides to avoid weed incidence and one based on the use of the tillage inter-row).
VERTICAL EARTHQUAKE GROUND MOTION RECORDS: AN OVERVIEW

Recent research clearly shows the importance of including the vertical component of earthquake ground motion in seismic analysis and design. In addition, pioneering studies [e.g., Elnashai and Papazoglou (1997)] have explored and documented the characteristics of available near-field vertical ground motion records. As a follow-up, this paper complements earlier studies, and investigates additional far-field records and available downhole array vertical motion records. A total of 111 free-field strong motion records (from California) and available downhole array records are employed. Compared to near-field records, far-field records generally contain more energy at longer periods. Based on the available data, response spectra are presented for near-field and far-field records respectively. The currently scarce downhole-array vertical motion records show that significant amplification may occur within the top 10-20 m soil layers. A simple one-dimensional (ID) vertical wave propagation model did not appear adequate for modelling the observed downhole array response. In using such a simplified model, very high viscous damping in the range of 15-25% was needed to match the recorded downhole vertical response, even for small tremors. Additional data and research are required [Beresnev et al., 2002] towards the development of a rational vertical motion site response analysis procedure.
High breakdown characteristic /spl delta/-doped InGaP/InGaAs/AlGaAs tunneling real-space transfer HEMT

A novel /spl delta/-doped InGaP/InGaAs/AlGaAs tunneling real-space transfer high-electron mobility transistor (TRST-HEMT) has been successfully fabricated by low-pressure metal organic chemical vapor deposition (LP-MOCVD). Three-terminal N-shaped negative differential resistance (NDR) phenomenon due to the hot electrons real-space transfer (RST) at high electric field is observed. Two-terminal gate-to-drain breakdown voltage is more than 40 V with a leakage current as low as 0.27 mA/mm. High three-terminal on-state breakdown voltage as high as 19.2 V and broad plateau of current valley as high as 15 V are achieved. These characteristics are attributed to the use of high Schottky barrier height, high bandgap of InGaP Schottky layer, /spl delta/-doping, and GaAs subspacer layers. The measured maximum peak-to-valley ratio (PVR) value is 2.7.
CUBESAT CLOUD: A FRAMEWORK FOR DISTRIBUTED STORAGE, PROCESSING AND COMMUNICATION OF REMOTE SENSING DATA ON CUBESAT CLUSTERS

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CUBESAT CLOUD: A FRAMEWORK FOR DISTRIBUTED STORAGE, PROCESSING AND COMMUNICATION OF REMOTE SENSING DATA ON CUBESAT CLUSTERS By Obulapathi Nayudu Challa December 2013 Chair: Janise Y. McNair Major: Electrical and Computer Engineering CubeSat Cloud is a novel vision for a space based remote sensing network that includes a collection of small satellites (including CubeSats), ground stations, and a server, where a CubeSat is a miniaturized satellite with a volume of a 10x10x10 cm cube and has a weight of approximately 1 kg. The small form factor of CubeSats limits the processing and communication capabilities. Implemented and deployed CubeSats have demonstrated about 1 GHz processing speed and 9.6 kbps communication speed. A CubeSat in its current state can take hours to process a 100 MB image and more than a day to downlink the same, which prohibits remote sensing, considering the limitations in ground station access time for a CubeSat. This dissertation designs an architecture and supporting networking protocols to create CubeSat Cloud, a distributed processing, storage and communication framework that will enable faster execution of remote sensing missions on CubeSat clusters. The core components of CubeSat Cloud are CubeSat Distributed File System, CubeSat MapMerge, and CubeSat Torrent. The CubeSat Distributed File System has been created for distributing of large amounts of data among the satellites in the cluster. Once the data is distributed, CubeSat MapReduce has been created to process the data in parallel, thereby reducing the processing load for each CubeSat. Finally, CubeSat Torrent has been created to downlink the data at each CubeSat to a distributed set of ground stations, enabling faster asynchronous downloads. Ground stations send the
New technological ventures: is success preordained?

The authors present a longitudinal study of 15 ventures, to identify important differences in the management characteristics and processes between successful and unsuccessful companies. The 15 are a stratified sample from a database of 68 on which the authors have detailed data from the original business plans. Management turnover, ability to resolve conflicts, meeting development goals, and other indicators of management behavior did not vary between the successful and unsuccessful firms, nor did adaptability. Once the product was introduced, companies encountering difficult markets adapted quickly by developing new products-but without success. Thus the initial product choice is crucial, and seems to be better if the team which makes it is relatively complete, representing diverse functions. <<ETX>>
Deacetylasperulosidic Acid Ameliorates Pruritus, Immune Imbalance, and Skin Barrier Dysfunction in 2,4-Dinitrochlorobenzene-Induced Atopic Dermatitis NC/Nga Mice

The prevalence of atopic dermatitis (AD), a disease characterized by severe pruritus, immune imbalance, and skin barrier dysfunction, is rapidly increasing worldwide. Deacetylasperulosidic acid (DAA) has anti-atopic activity in the three main cell types associated with AD: keratinocytes, mast cells, and eosinophils. Our study investigated the anti-atopic activity of DAA in 2,4-dinitrochlorobenzene-induced NC/Nga mice. DAA alleviated the symptoms of AD, including infiltration of inflammatory cells (mast cells and eosinophils), epidermal thickness, ear thickness, and scratching behavior. Furthermore, DAA reduced serum IgE, histamine, and IgG1/IgG2a ratio and modulated the levels of AD-related cytokines and chemokines, namely interleukin (IL)-1β, IL-4, IL-6, IL-9, IL-10, IL-12, tumor necrosis factor-α, interferon-γ, thymic stromal lymphopoietin, thymus and activation-regulated chemokine, macrophage-derived chemokine, and regulated on activation the normal T cell expressed and secreted in the serum. DAA restored immune balance by regulating gene expression and secretion of Th1-, Th2-, Th9-, Th17-, and Th22-mediated inflammatory factors in the dorsal skin and splenocytes and restored skin barrier function by increasing the expression of the pro-filaggrin gene and barrier-related proteins filaggrin, involucrin, and loricrin. These results suggest DAA as a potential therapeutic agent that can alleviate the symptoms of AD by reducing pruritus, modulating immune imbalance, and restoring skin barrier function.

In order to uncover the reality of the trap present in the MQW consisting of GaN‐InGaN pair, extraction of the location and the energy level of the trap using RTN experiment were applied for the first time. Through simplification of the complex MQW into an approximate structure, we found the trap of each sample is located very close to p‐GaN interface.
Fuzzy-controlled active state-of-charge controller for fasting the charging behavior of Li-ion battery

A fuzzy-controlled active state-of-charge controller (FC-ASCC) is presented to adaptively program the charging behavior of the Li-ion battery. The proposed FC-ASCC can provide two charging modes (SM and CM) instead of the usual CV mode for improving the charging trajectory of the Li-ion battery. A fuzzy-controlled strategy is built with a set of membership functions to prescribe the charging process in a safe charging region. A design example is conducted with simulation and experiment for accessing the predicted charging performance of the Li-ion battery. The FC-ASCC can actually increase the charging speed over 23% comparing with the traditional charging system.
Precesion Agriculture for Drip Irrigation Using Microcontroller and GSM Technology

Drip irrigation is now a common phenomenon gaining popularity especially in the states like Rajasthan where water scarcity is a day to day affair. For drip irrigation a small over head water tank in used which supply water to the drip system. Usually the geographic systems as well as the cost do not permit a bigger tank. This tank generally gets vacated and a farmer needs to be always attentive to refill the over head tank from his well or cannel by an electric pump, mostly this need arises in the night as the availability of power is not whole day. This involved a lot of risk and cost on the part of farmer. The simple and low cost gadget that has been work upon, not only control the starting and stopping of motor by sending a simple SMS through a GSM mobile but also gets the return SMS showing level of water in overhead tank. The application of the gadget is not only limited to the use for a farmer & but can be beneficial for any process industry in which level of a chemical or any liquid need to be crucially controlled and monitored from far end, may be even from the home of a supervisor with no constraints of time or place for controlling the operations.
An approach to enhance the harmonic sources identification process

Harmonics can create unwanted impacts on power systems and to end-users. Electrical utilities, manufacturers and customers have been bothered by harmonic distortion problems in power systems. IEEE-519 has set up a recommended practice on this issue that has been adopted by many utility companies. In order to ensure power quality within their service territory, the utility industry has established a scheme to identify harmonic sources that exceed the limits. This harmonic source identification scheme works in most cases. However, it may affect normal operation of the system under certain conditions. In addition, it may miss important system phenomena such as resonance. This paper presents an approach to locate the harmonic sources in a radial distribution feeder that can minimize the interference of normal operation. It enhances the ability to identify the current harmonic source. A sample system is used to illustrate this approach and simulation results are presented.
Complexity in Managing Refurbishment Design Process: Malaysian Experience

In Malaysia, building refurbishment is expected to become more important in the next five years. This is due to largest government allocations for refurbishment works in ninth and tenth Malaysian Plan and high demand for refurbishment works. The investigation also introduced the functions of integrative mechanisms, which consist of coordination devices and the degree of involvement of key participants in decision- making, as a means to integrate management into the design process. This is paramount in order to increase information-processing capacity during the design process. Seven (7) dominant factors were identified concerning with the design process of refurbishment projects. The variables are: availability of design information, statutory requirements, clients' attributes, clients' needs, design fees, material availability and ease of access. The greater part of design process suffers from uncertainty nature of the projects. Almost half of refurbishment projects prepare design with less than 70 percent information available. The design performance recorded more than three-quarters of refurbishment projects exceed the targeted design time and cost. It was also found that integrative mechanisms contribute toward the improvement of the design performance. In addition, a high degree of involvement during the construction stage could improve refurbishment design performance. From the findings, it could be concluded that the major part of the design process of refurbishment projects suffered from the uncertain nature of the projects. The implementation of integrative mechanisms indicated the possibility of improving some of the design performance.
