Malignant hyperthermia (MH) is a skeletal muscle pharmacogenetic disorder that manifests as a hypermetabolic response to powerful volatile anaesthetic gases like halothane, sevoflurane, desflurane, isoflurane, and the depolarizing muscle relaxant succinylcholine, as well as stressors like vigorous exercise and heat in human body. Anesthetics with an MH reaction rate vary from 1:10,000 to 1:250,000. On the other hand, the incidence of genetic anomalies might be as high as one in 400 people. Humans, specific pig breeds, dogs, and horses are all affected by MH. Hyperthermia, tachycardia, tachypnea, increased carbon dioxide generation, increased oxygen demand, acidosis, hyperkalaemia, muscular stiffness, and rhabdomyolysis are all typical indications of MH, all of which are associated with a hypermetabolic response. The condition is likely to be fatal if untreated. An early diagnostic indication is a rise in end-tidal carbon dioxide despite enhanced minute ventilation. Humans inherit the condition in an autosomal dominant form, whereas pigs inherit it in an autosomal recessive form. The pathophysiologic alterations are caused by an uncontrolled surge in myoplasmic calcium, which triggers biochemical pathways associated to muscle activation. A deficiency in the ryanodine receptor is the most common cause of the condition. The RYR1 gene, which is found on chromosome 19q13.1, has over 400 variations, at least 34 of which are linked to MH. In CACNA1S, less than 1% of variations have been discovered, although not all of them are causative. The in vitro contracture response of biopsied muscle to halothane, caffeine, and in certain centres, ryanodine and 4-chloro-m-cresol is used in diagnostic testing. The discovery of the genetic alterations has led to the development of DNA testing for MH susceptibility. Dantrolene sodium is a particular antagonist that should be provided in every setting where general anaesthesia is used. Because of a better knowledge of the clinical manifestations and pathophysiology of the disease, mortality has decreased from 80% thirty years ago to less than 5% in 2006.

The 2019 coronavirus pandemic disease has spread globally. SARS-CoV-2 species in the first and second time waves and new species of Omicron show symptoms in the third wave of COVID-19 worldwide. The first patients were found in Wuhan, China. Due to COVID-19, the main highly infected countries are the U.S. China, European countries, and also India. The SARS-CoV-2 species are betacoronavirus infections that spread from person to person and another object. The COVID-19 SARS species (RNA virus) is majorly infected in the lungs. Some vaccines and some drugs are provided worldwide, but these vaccines are not proper treatment for COVID-19. These vaccines boost immunity and provide relief from the symptoms of COVID-19, but they are not a proper treatment. Antimalarial drugs, antiviral drugs, monoclonal antibodies, and antibiotics are used in the current treatment to stop mechanisms like fusion entry and replication. Identification of COVID-19 through symptoms and properly identified by RT-PCR Prevention and treatment of COVID-19 disease is a promising new research area for pharma companies to develop novel therapeutic agents' inhibition for COVID-19 pathological targets.

Published: January 2023

Field trials were conducted in two agro-climatic zones of the country (Lungi and Kabala) to evaluate the effect of planting methods and inter-row spacing on the growth parameters of three Bambara groundnut cultivars. The experiment consisted of a factorial 18 treatment combinations of two planting methods (mound and flat), three inter-row spacing (50 cm x 10 cm, 50 cm x 15 cm, and 50 cm x 20 cm), and three Bambara groundnut cultivars (Lubam1, Lubam 2, and Kabam 1). The study shows that planting Bambara groundnut using mounds produced higher values of the assessed growth parameters compared to planting Bambara groundnut on flat land. The result further shows that the wider inter-row spacing (50 cm x 20 cm) on average recorded the highest value for all the assessed growth parameters. Furthermore, Kabam1 was observed to have recorded the highest value for all the growth parameters in both locations. Thus, for optimum growth parameters to be achieved, it is recommended that Kabam1 should be planted on mound using the inter-row spacing of 50 cm x 20cm.

Published: January 2023

Application of seismic isolation system is important in bridges design, primarily in seismically active countries. Bridges are prone to damage from seismic forces. Elastomeric isolation bearings have been applied in short-span bridges for some time in most countries. These bearings are preferred because of the low maintenance cost. However, these bearings are not reliable when subjected to large displacement and low temperatures. In the other hand, friction sliding bearings shows better performance under the former circumstances despite its use is still limited to long-span bridges and has not been explored further. This paper describes a performance evaluation of seismically-isolated short-span reinforced concrete bridge using friction pendulum system (FPS). Seismic performances of non-isolated and isolated models from the reference bridge functioning as light rapid transit (LRT) bridge in Jakarta are investigated using nonlinear time history analysis. The results demonstrate that isolated bridges with FPS performed better than non-isolated bridges under 1000-year earthquake as shown by reductions of base shear force, absolute deck acceleration, and acceleration amplification ratio. Comparisons of isolated bridges with different FPS friction types and arrangement have demonstrated that the reference bridge with all Type A friction (�0 = 0.050) applied, performed the best among all other configurations.

Being one of the largest developing countries, Indonesia has high intensity of infrastructure development. Because of its exact location between the Pacific plate and Eurasian plate, it is necessary to consider the earthquake load in planning a building or other structure. The fundamental period is a function of the lateral stiffness of a building, which will play an important role in carrying lateral loads, such as earthquakes. Earthquake loads experienced by the structure will result in deformation of the building. For building planning in Indonesia, national standards (SNI,) which are continuously adapted to the conditions of the earth and technological developments in construction, are used. This study aims to determine the impact of changes to the standards applied in terms of changes in cross-sectional dimensions, fundamental periods, and building deformation, using modeling in the auxiliary program. Compared with modeling the existing structure in the initial state (model 1), the existing structure with the latest loading (model 2), and the planning results using the latest standard (model 3).Based on the results of the analysis, it was found that the beam dimension changes in the form of an 88% increase in cross-sectional area on the 2nd and 3rd floors of the B9 beam, the largest change in the column cross-sectional dimensions on the K3 column on the 4-7th floor and the K8 column on the 3-7th floor with a large increase of 104%, the change in the fundamental period model 3 increased by 22% from model 1 and increased by 19% from the period model 2, and obtained a change in the form of displacement. X direction in model 3 experienced a maximum increase of 210% against model 1 on the roof floor and in model 3 against model 3 2 increased by 37% on the roof floor for displacement Y direction in model 3 experienced a maximum increase of 192% against model 1 on the roof floor and an increase of 29% against model 2 on the roof.

Authors: Almubarok Falakush Shobah , Mudiyono Rachmat , S Soedarsono
Published: January 2023

The pavement Condition Index (PCI) method serves to measure the severity of pavement damage based on 3 main categories: (1) type of damage, (2) severity of damage, and (3) amount or density of damage. PCI is a numerical index whose values range from 0 to 100. A value of 0 indicates the pavement was in very damaged condition, while a value of 100 indicates that the pavement was still excellent. A survey was conducted on Jalan Tregguli - Welahan along � 1 km divided into several segments to identify road damage. Each segment was 100 m apart. PCI for Trengguli - Welahan road segment which belonged to 0 � 10 (failed) of 0%, 11 � 25 (very bad) of 11%, 26 � 40 (bad) of 28%, 41 � 55 (moderate) of 8%, 56 � 70 (good) of 12%, 71 � 85 (very good) of 19%, and 86 � 100 (Perfect) of 22%, The average PCI for Trengguli Welahan road segment is of 54.36. The findings classified road damages into road patches, longitudinal/transverse cracks, holes, and joint cracks. The PCI value is 54.36 (medium). Based on data on the PCI value and the percentage of damage on the road of Trengguli - Welahan, there is a high correlation between the two variables.

Published: January 2023

This paper presents the results of an assessment of the existing 5-storey building built in 1980, which aims to determine the level of safety against the most recent standards. The method used is non-destructive testing, collecting planning data in the form of as built drawings and implementation data. The assessment of the existing structure consists of an evaluation of the condition of the material, structural system, and analysis of the structure using the latest load standards. The test results of the existing structural material show that the compressive strength of the concrete still meets the requirements based on SNI-2847-2019. The results of the evaluation of the structure against earthquake loads show that the performance of the structure has a mass participation of 100% and the dynamic base shear force (V) reaches 100% of Vstatic therefore it meets the requirements in SNI 1726-2019. The results of the evaluation of the performance of the structure show that the lateral drift and P-delta effects still meet the requirements of the most recent standards. Horizontal and vertical structural irregularities are found in the existing structural system. The structure's overall performance level (X and Y direction earthquakes) is Damage Control. These results are still permitted for structures with a priority factor (Ie) 1.50, with an earthquake return period of 2500 years.

This paper has aimed to try and establish a successful weld joint between AISI 304L stainless steel as a stud and AISI 316L stainless steel as a plate by using an arc stud welding process. The effect of different current and time welding on the torque results was experimentally studied, by using three-level of each process parameters. The post-weld heat treatment (PWHT) was carried out on the optimum sample of torque, to study the effect of PWHT on mechanical properties (torque and hardness) and microstructure of the welding zone. In the present work, a3-D finite element model was developed by using ANSYS software version 18 to analyze the influence of time and current welding on the temperature distribution and residual stresses of the resultant welded joints. A transient thermal model was built to predict the temperature distribution whereas the residual stresses were determined by using a static structural model. The PWHT has been used to reduce the amount of residual stresses and enhance the mechanical properties of the welded joint. The micro-hardness based on the Vickers test and the microstructure of welded specimens of with and withoutPWHT have been investigated. The simulation results reveal that the generated temperature and the residual stress is strongly affected by the time and current welding. The mechanical test results indicated that the PWHT prompted an improvement in the hardness values.

The increase of clean energy requirement is still enhanced in order to reduce the effect of the global warming therefore, the augmentation of solar energy applications like the solar collectors is attended. The presentstudy of the Flat Plate Solar Collector (FPSC) is performed during the three days’ time (2,3 and 4 of June). Where, the testing time is specified from 09:00Am up to 03:00Pm in order to give more obvious data. Moreover, the energy and exergy analysis equations are utilized to study the 1st and 2nd law of thermodynamics and to provide more appropriate results about the performance of the FPSC. The conducted results show an enhancement in the FPSC efficiency with respect to the increase of the solar irradiance where the last one was explained through one-day time. Furthermore, the FBSC exergy and energy efficiencies conduct the same behaviors during the daytime due to the effect of the solar radiation. In addition, the useful exergy and the exergy efficiency are raised with the progression of time until it reaches approximately midday and then dropped down because of the solar radiation reduction.

The wide application of pneumatic actuator in electricalandelectronics sectors are undeniable hence ask for a good control environment.PID controller is always known with easy implementation and good control performance. Butthe limitation of the PID static gains to effectively control the complex nonlinear system is unavoidable. This suggests the enhancement of the PI controller with a nonlinear adaptive interaction algorithm (AIA) thus develop the nonlinear adaptive AIA PI. The modification is introduced by integrating a nonlinear gain function that adaptively tunes the AIA parameter, hence resulting the best tuning of the PI control gains. The nonlinearities inherent in the system parameters are believed to be handled by the integration, therefore improving the controller performances while maintaining the pneumaticactuator at the desired position. It was proved that improved error performance criteria’s, settling time and overshoot were resulted by the nonlinear adaptive AIA PI compared to fix adaptive AIA PI, and significantlygood compared to conventional PID and PI controllers. Besides, about 19.72%, 11.72%, and 0.22% overshoot were successfully reduced by the nonlinear adaptive AIA PI compared to optimal PSO PI, PSO PID, and PSO AIA, respectively. To conclude, the developmentof the proposed controller is demonstrated to function well and offers an alternative tuning strategy in other electrical and electronic engineeringapplications.

Majority of projects failed due to mismanagement factors such as funds, planning, time, and resources. With the adoption of Project Management Office (PMO) in an organization, it able to manage the projects practises through a distinctive office dedicated to project management with specific roles and functions that should be followed by the project officer for all the projects. The positioning of PMO in the organisational structure and its job responsibilities, are critical factors in project success. This paper presents a study to uncover the topology of PMO in the project-based organizations in United Arab Emirates (UAE). This qualitative study was conducted through interviews with twenty professionals working in PMO from four companies in the UAE. Based on the findings from the interview sessions, PMOs can be divided into three types: supportive, controlling, and directive. The result indicates that the type of PMO chosen have a significant impact on the efficiency of the project delivery. While controlling PMO approach, it is desired to "clear-house" the activities, processes, procedures, documentation, and more, the organisation requires that the help be used in addition to providing it, supportive PMO is the best choice if the goal is to establish a "rein in" of project management data that all project managers within the firm may freely access. Furthermore, Directive PMO goes beyond simple control and "takes over" projects by providing the necessary resources and project management expertise. According to the findings of the interviews, the PMO performs a variety of functions, including project support, training, lesson-learned maintenance, project management tool and software support, project control, inter-project communication, managing shared resources, and encouraging good project management and decision-making. PMO forecasts future resource requirements, plans for strategic, non-billable, and billable usage, and assigns appropriate resources to appropriate projects at appropriate times. This improves resource utilisation efficiency, and significantly lowers project resource costs.

Risk control and management are becoming increasingly important in many organisational operations. It goes beyond the business sector to include security organisations like police departments. The fact that police officers engage in a widerange of daily activities that expose them to a variety of potentially hazardous situations Police risk management includes both physical and financial aspects. Risk identification is the first step in the risk management process, followed by risk analysis, risk evaluation, and risk treatment. According to the literature, the Dubai Police Department has no framework in place to fully manage risks and evaluate the effectiveness of police operations. Early warning systems are critical for detecting potential severe RM because police departments must rely on them to manage risks and keep track of any potential new risks. As a result, the UAE police department's risk management strategy was investigated in this paper. It classified the data collection process using exploratory factor analysis, which wasa quantitative approach. A self-administered survey yielded 381 valid questionnaires from Dubai Police Department officers. The study's findings revealed that risk identification, risk analysis, risk evaluation, and risk response are the four fundamental steps of effective risk management. The Crobach Alpha test was used to assess the consistency and reliability of the data, and the result was 0.814, indicating that the data is suitable for use. Only one of the twenty indicators, which were divided into four groups for risk management, was weak according to outliers and communalities tests. The risk management process was accurately described by another 20 factors. Total variance extraction yielded a rate of 57.130 percent, which was higher than the required 50%. As a result, the risk management procedure investigated in this study may be useful for effectively managing risks in the UAE police force.

Recycling is an excellent method to manage institutional solid waste and reduce the environmental carbon footprint. However, the outbreak of the COVID-19 pandemic has caused unprecedented chaos and affected recycling activities in UTHM. Therefore, the trend of carbon reduction through recycling activities in UTHM was determined to investigate the impact of the COVID-19 pandemic on the trend of carbon reduction. The data was collected from the recycling center in UTHM and the carbon reduction was further calculated to compare the difference before and after the pandemic outbreak. The weight of paper products collected was the highest, accounting for more than 75%, while the weight of aluminium collected was the lowest, accounting for less than 1%. Furthermore, it was found that the trend of carbon reduction increased steadily in 2019. However, the outbreak of the COVID-19 pandemic has caused the trend to plunge and approach zero in March 2020. Nevertheless, once the COVID-19 pandemic was under control, the carbon reduction trend improved and peaked again in 2021. In addition, paper products achieved the highest of the total carbon reduction at 5143.072 tCO2e while aluminium was the lowest at 0.357 tCO2e. The highest total carbon reduction was achieved in 2019 with 1980.168 tCO2e while the lowest was recorded in 2020 with 1220.932 tCO2e. As a result, the Covid-19 Pandemic had a significant impact on the recycling rate in UTHM, which resulted in a reduction in the total amount of carbon reduction.

Unmanned Aerial Vehicle (UAV) is an advanced technology that can be control remotely. It hovers up in the air and travel with different height and distance depending on the capability of the UAV. Originally, this technology was invented for military practice. Now, the innovation of UAV is growing and have contribute to various field including terrain mapping in surveying work. Carrying out mapping task in terrain such as mountain, valley, plateau, or rainforest can be a difficult task in-terms of time, practicality and cost. Another challenge is when the survey area is permanently clouded over and the limited availability of aircraft platforms and the orbit features of satellites causing difficulties to obtain high quality photos. Therefore, there are much research that used UAV technology to do mapping work and obtain Digital Terrain Model (DTM), Digital Surface Model (DSM) and Digital Elevation Model for various purposes. In this study, systematic literature review using thematic analysis methodology was used to review, evaluate and combine relevant literature review. The aim of this study is to categorise the application for terrain mapping using UAV and also to identify the system and result improvement of UAV during the usage in terrain mapping.
