Influence factors in government enterprise architecture establishment process: a preliminary findings

As part of the public sector modernisation plan, governments seek to offer their citizens a seamless service delivery. Due to the poor performance of Electronic Government (e-Gov) approach, Government Enterprise Architecture (GEA) initiative is introduced to fulfil the initial e-Gov purpose. GEA serve as an umbrella for explaining the relationships among the projects and managing change in government. Yet the focus of most GEA initiative is mainly towards the technical aspects such as framework, data modelling and technology architecture. Inadequate attention is given to the GEA activities during the establishment process. Therefore the paper aims to determine what are the factors influences the GEA establishment process. The preliminary study identifies six main themes with 23 factors gathered from existing literature and interviews with respondents from Malaysian Public Sector agencies that have implemented GEA.
Ultraviolet irradiation doses for coronavirus inactivation -review and analysis of coronavirus photo inactivation studies

Background: To slow the increasing global spread of the SARS-CoV-2 virus, appropriate disinfection techniques are required. Ultraviolet radianon (UV) has a well-known antiviral effect. But measurements on the radiation dose necessary to inactivate SARS-CoV-2 have not been pub- lished so far. Methods: Coronavirus inactivation experiments with ultraviolet light performed in the past were evaluated to determine the UV radiation dose required for a 90% virus reduction. This analysis is based on the fact that all coronaviruses have a similar structure and similar RNA strand length. Results: The available data reveals large variations, which are apparently not caused by the coronaviruses but by the experimental conditions selected. If these are excluded as far as possible, it appears that coronaviruses are very UV sensitive. The upper limit determined for the log-reduction dose (90% reduction) is approximately 10.6 mJ/cm2 (median), while the true value is probably only 3.7 mJ/cm2 (median). Conclusion: Since coronaviruses do not differ structurally to any great exent, the SARS-CoV-2 virus – as well as possible future mutations – will very likely be highly UV sensitive, so that common UV disinfection procedures will inactivate the new SARS-CoV-2 virus without any further modification.
The Role of PDGFRA in Predicting Oncological and Immune Characteristics in Pancreatic Ductal Adenocarcinoma

Objective Pancreatic ductal adenocarcinoma (PDAC) is a lethal solid gastrointestinal malignancy with poor immune infiltration and a limited response to immunotherapy. The aim of our study was to explore the predictive value of platelet-derived growth factors (PDGFs) and their receptors (PDGFRs), which are widely expressed in various tumor cells. Methods Transcriptomic data with follow-up information were obtained from the GEO, TCGA and ArrayExpress. The Kaplan–Meier (KM) method and univariate Cox (UniCox) proportional hazard regression were used to show the survival outcomes of the groups. Immune infiltration was analyzed using the online databases TISCH, TISIDB, TIMER2.0, and TIDE as well as the R packages “estimate” and “GSVA. ” Mutation and functional enrichment analyses were conducted using the R packages “maftools,” “clusterProfiler,” and online repository HOME for Researchers. Finally, the results were validated in 79 samples from our cancer center. Results Survival analysis using public databases and the FUSCC cohort indicated PDGFRA to be associated with prolonged overall survival (OS) (both p < 0.05). PDGFRA expression was highest in cancer-associated fibroblasts (CAFs) of PDAC, as validated in public databases and cell lines from our cancer center. The high expression of PDGFRA was associated with increased immune infiltration and potent T cell cytotoxicity in PDAC. Conclusion In summary, high PDGFRA expression is associated with increased immune infiltration and prolonged OS. This finding might provide a new strategy for regulating immune cell infiltration in PDAC and improving the efficacy of immunotherapy.

How Agile Methods Inspire Project Management - The Half Double Initiative

Increased complexity in projects has forced new project management initiatives. In software development several agile methods have emerged and are today highly implemented in practice. Observations of general project management practice show how it has been inspired by agile software development, but very little research addresses the issue of agile project management. In order to understand and to provide suggestions for future practice on how agility can be incorporated in general project management, this paper provides an analysis which compares ten characteristics of agile software development (identified in theory) and the Half Double Methodology developed by the Danish Project Half Double initiative; a Methodology developed with practitioners and tested in seven Danish case companies. The analysis shows how the general project management to a great extent has been inspired by agile methods, but also that general project management may be able to find more inspiration from agile methods.
Comparative Analysis of Power Quality Instruments in Measuring Power under Distorted Conditions

Abstract This paper aims to evaluate the performance of commercial power quality (PQ) instruments. By using a high precision programmable voltage and current source, five meters from different manufacturers are analyzed and compared. At first, three-phase voltage signals are applied to those PQ instruments, considering harmonic distortion, voltage dip, voltage swell, as well as unbalanced voltages. These events are measured, compared and evaluated considering the different instruments. In addition, voltage and current signals are applied under different conditions, with and without harmonic and unbalances, in order to obtain the measurements of electrical power. After analyzing the data generated in all these tests, efforts are focused on establishing a relationship between the accuracy of the measurements. Considering the percentages of errors, a score is assigned to each instrument. The tests have shown “excellent” and “good” results regarding measuring active and apparent power, as well as power factor. However, for non-active power, almost all instruments had lower performance. This work is relevant considering that Brazil is deploying standardization in terms of power quality measurements aiming towards regulatory procedures and index limits.
Low SAR Microstrip Patch Antenna for Mobile Phone

Abstract The aim of this article is to design a new microstrip-fed patch antenna for cell phone applications. The antenna design is composed of slots and FR-4 dielectric substrate fed by a partial ground plane and a microstrip line. The user’s effects on antenna performances are also analyzed using standard SAM phantom. The specific absorption rate (SAR) values of proposed antenna are evaluated for different frequency bands considering cheek position of talk mode. The proposed antenna has an impedance bandwidth (–10 dB reflection coefficients) 100 MHz (0.87–0.97 GHz, lower band), 50 MHz (1.47–1.52 GHz, middle band), and 150 MHz (1.78–1.93 GHz, upper band), which can cover GSM 900 MHz, GPS 1,500 MHz, DCS 1,800 MHz, PCS 1,900 MHz, and GSM 1,900 MHz bands. Moreover, the proposed antenna produces lower SAR values in the human head than that of a dipole and helical antenna.
Effects of temperature and precipitation on litterfall phenology in four evergreen broad‐leaved forests of southern China

Vegetative and reproductive growth of subtropical and tropical forests plays an important role in regulating carbon cycle and maintaining food web dynamic balance. Here, we used litterfall and climatic data during 1998–2017 at four evergreen forest sites in southern China to analyze temporal variations of community phenology and their climate drivers. Results show that two southwest forests have unimodal patterns with leaf litterfall peaks during dry season, while two southeast forests have bimodal patterns with the first peaks during rainy season and the second peaks during rainy and dry seasons respectively. Peaks of flower litterfall for the four forests occurred during the transitional period between dry and rainy seasons, while peaks of fruit litterfall appeared either at the end of the rainy season at the two southern sites or in the dry season at the two northern sites. Leaf litterfall correlates significantly positively with preseason maximum temperature at the four sites, but significantly negatively with preseason precipitation at two southwest sites. By contrast, flower and fruit litterfall correlates significantly positively with preseason temperature and precipitation at only three and two sites. Moreover, leaf, flower, and fruit litterfall exhibits a 12‐month cycle, which is consistent with the 12‐month cycle of monthly temperature and precipitation. Flower and fruit litterfall displays also multiyear cycles between 18 and 48 months, however, it is inconsistent with the multiyear cycles of monthly temperature and precipitation. Our study highlights that temperature and precipitation are key factors affecting litterfall variations in different time scales in southern China.
Effects of Coanda jet direction on the aerodynamics and flow physics of the swept circulation control wing

Over the last decade, many flight tests of the conventional/canard/flying-wing layout UAVs (unmanned aerial vehicle) have proven that the trailing-edge circulation control (CC) is an effective method to generate a significant rolling moment for the rolling control. However, the Coanda jet’s three-dimensional effects, especially the Coanda jet direction, on the design of UCAVs (unmanned combat air vehicle) have not been revealed and discussed clearly yet. In order to solve this problem, the effects of the Coanda jet direction on the swept wing’s aerodynamics and flow physics are investigated in detail in this paper. An in-house CFD(computational fluid dynamics) solver HyperFLOW with the Spalart–Allmaras for Rotation and Curvature turbulence model and the velocity inlet boundary has been validated by 2-D and 3-D CC cases and is used in this work. The research reveals that compared with the Coanda jet in the freestream direction (FJ jet), the Coanda jet perpendicular to the trailing edge (PJ jet) has a more significant impact on the aerodynamic loads and flow structures for swept wings, including increasing lift, drag, and nose-down moment, enhancing the wingtip vortex and weakening the thickness vortex. In contrast, the FJ jet performs better in improving the lift-to-drag ratio of swept wings. On a typical UCAV, the generalizability of the conclusion about the Coanda jet direction effects on the aerodynamic characteristics is verified. The current research gets an insight into the three-dimensional effects of the trailing-edge CC and provides solid support for implementing the CC technology into practical aircraft concepts.
Voice-Enabled Intelligent Virtual Agents for People With Amnesia: Systematic Review

Background Older adults often have increasing memory problems (amnesia), and approximately 50 million people worldwide have dementia. This syndrome gradually affects a patient over a period of 10-20 years. Intelligent virtual agents may support people with amnesia. Objective This study aims to identify state-of-the-art experimental studies with virtual agents on a screen capable of verbal dialogues with a target group of older adults with amnesia. Methods We conducted a systematic search of PubMed, SCOPUS, Microsoft Academic, Google Scholar, Web of Science, and CrossRef on virtual agent and amnesia on papers that describe such experiments. Search criteria were (Virtual Agent OR Virtual Assistant OR Virtual Human OR Conversational Agent OR Virtual Coach OR Chatbot) AND (Amnesia OR Dementia OR Alzheimer OR Mild Cognitive Impairment). Risk of bias was evaluated using the QualSyst tool (University of Alberta), which scores 14 study quality items. Eligible studies are reported in a table including country, study design type, target sample size, controls, study aims, experiment population, intervention details, results, and an image of the agent. Results A total of 8 studies was included in this meta-analysis. The average number of participants in the studies was 20 (SD 12). The verbal interactions were generally short. The usability was generally reported to be positive. The human utterance was seen in 7 (88%) out of 8 studies based on short words or phrases that were predefined in the agent’s speech recognition algorithm. The average study quality score was 0.69 (SD 0.08) on a scale of 0 to 1. Conclusions The number of experimental studies on talking about virtual agents that support people with memory problems is still small. The details on the verbal interaction are limited, which makes it difficult to assess the quality of the interaction and the possible effects of confounding parameters. In addition, the derivation of the aggregated data was difficult. Further research with extended and prolonged dialogues is required.
Formulation Design and Ex Vivo Evaluation of Carbopol -Incorporated Mucoadhesive Thermoreversible gels of Sucralfate for Rectal Drug Delivery

Aim: The present research is focused on preparation of Thermoreversible gels and screening ex vivo anti-inflammatory activity using croton oil induced hemorrhoid model. Study Design: The animals were divided into four groups, n=8. After overnight fasting, hemorrhoids were induced by inserting sterile cotton swabs soaked in croton oil preparation into the anus of all group animals except normal control group. Place and Duration of Study: Depart of Pharmacology, Sree Vidyanikethan College of Pharmacy, Tirupati. between October 2021 to December 2021 Methodology: Experimental runs for optimization of formulation with the help of 23 factorial designs were designed [1]. Design of Expert program 6.0. 6 (Stat-Ease Inc. Minneapolis, MN) was used to create formulations. Formulations were optimized using full factorial de­sign. In situ rectal gel was prepared by the cold meth­od [2]. As shown in Table 1, P188 was dissolved in DDW (de-ionized distilled water) including drug (1% w/v) at room temperature, and it was stored at 4°C for complete solubilization of P188. Carbopol solubilized in DDW, HPMC K4M and other mu­coadhesive polymers were then slowly added to the prepared solution with continuous agitation at 4°C, and were kept for 24 h before their use. The composi­tion of developed gel formulations is summarized in Table 1. Results: Results In the first set of experiment, the application of croton oil to recto anal portion of rats induced significant increase in the Recto anal coefficient and serum level of pro inflammatory cytokines such as IL-6, and TNF \(-a\) it also showed a significant increase in recto anal portion compared to normal control animals. However, the treatment with Sucralfate containing Thermoreversible gels has maintained the RAC and Interleukin -6 levels near to normal control group. These findings were further supported by histopathological examination wherein the animals treated with optimized formulation showed significant reversal in the severity of inflammation, vasodilatation in the recto anal portion, and presence of inflammatory cells. Conclusion: The findings of the present study suggest that the improved experimental model described in the present work has advantages and the model has a provision for quantifying the inflammatory exudates in the induced experimental hemorrhoids. Also, it was found that, the optimized formulation ameliorated the croton oil-induced hemorrhoids in rats.

Model-Based Decision Support for Protected Cultivation of Sweet Pepper

Abstract: A crop growth model for sweet pepper was applied to simulate quantity and timing of fruit set and harvest. Climate input for the model was organised by means of online data platforms, linking directly to climate computer sensors. This information was processed and made available as model-input automatically via an ftp-server. Additionally, regular registration of fruit set and harvest was routinely performed on a weekly basis at the companies and entered manually into online data platforms. The processed model-input for registration was made available via the same ftp-connection. The model was complemented with a user interface, allowing instant simulation of simple climate scenarios. This provided the grower with information on the consequences of changes in greenhouse climate for fruit set and harvest. Initially, model results were solely supplied through a partnership with a cultivation advisory firm, acquainting the grower with the possibilities of the model-application. Later in the project, experienced growers used the application locally, allowing them to use the tool more frequently as support in their decision making.

Wireless power transfer and energy harvesting in distributed sensor networks: Survey, opportunities, and challenges

Distributed sensor networks have emerged as part of the advancements in sensing and wireless technologies and currently support several applications, including continuous environmental monitoring, surveillance, tracking, and so on which are running in wireless sensor network environments, and large-scale wireless sensor network multimedia applications that require large amounts of data transmission to an access point. However, these applications are often hampered because sensor nodes are energy-constrained, low-powered, with limited operational lifetime and low processing and limited power-storage capabilities. Current research shows that sensors deployed for distributed sensor network applications are low-power and low-cost devices characterized with multifunctional abilities. This contributes to their quick battery drainage, if they are to operate for long time durations. Owing to the associated cost implications and mode of deployments of the sensor nodes, battery recharging/replacements have significant disadvantages. Energy harvesting and wireless power transfer have therefore become very critical for applications running for longer time durations. This survey focuses on presenting a comprehensive review of the current literature on several wireless power transfer and energy harvesting technologies and highlights their opportunities and challenges in distributed sensor networks. This review highlights updated studies which are specific to wireless power transfer and energy harvesting technologies, including their opportunities, potential applications, limitations and challenges, classifications and comparisons. The final section presents some practical considerations and real-time implementation of a radio frequency–based energy harvesting wireless power transfer technique using Powercast™ power harvesters, and performance analysis of the two radio frequency–based power harvesters is discussed. Experimental results show both short-range and long-range applications of the two radio frequency–based energy harvesters with high power transfer efficiency.
