Authors: Munira Ibrahim Ireen , Liong Choong-Yeun , Abu Bakar Sakhinah , Farid Najmudd Ahmad 
Published: March 2021

Overcrowding is a major concern for the Emergency Department (ED) management at the public hospital under study. Although the number of patients in the Yellow Zone (YZ) of the department represents only 30% of the total visiting patient per day, the Key Performance Indicator (KPI) of the zoneâ€™s patientsâ€™ LOS (LOS) as well as waiting time are not achievable due to the resources constraints. Therefore, this paper discusses the application of Discrete Event Simulation (DES) approach on modeling the YZâ€™s daily operations. The model was developed using Arena software to assist the ED management to better understand their system behavior and causes for the high patientsâ€™ LOS and waiting time. The simulation outputs show that the bottleneck of the system is waiting for an available resource. A few scenarios were designed based on the discussion made with the ED management for possible improvement. The results show a significant reduction of 25% and 35% in the total average of patientsâ€™ LOS for the patients of the observation unit and the intensive unit respectively. Meanwhile, for the total average patientsâ€™ waiting time, the results show a reduction of 34% for the observation unit and 29% reduction for the intensive unit.Â Â Â

This research evaluates the level of environmental literacy of vocational students. The research method used is evaluative descriptive research method. The instrument used is the Environmental Literacy Test. The component of environmental literacy consists of environmental knowledge, attitudes, and "actions" or responsible behavior for the environment. Mastery of the environmental concept of vocational students is based on the achievement of environmental literacy in terms of knowledge and environmental understanding which consists of 8 indicators, i.e.: energy, pollution and contamination, forests, atmosphere / climate, water, waste, and sustainable development. The average mastery of environmental concepts is 51, which included to the low category. The highest knowledge and understanding are population indicators that is an average value of 68 and the lowest value is an atmospheric / climate indicator with an average value of 32. Attitudes and participation in overcoming environmental problems are included in the good category. They have tried to use alternative transportation such as by using bicycle or walking, reducing the use of electricity for lighting and cooling the space, using water as needed, and disposing the garbage in the proper place. Vocational students are still lacking in action as an effort to overcome environmental problems.Â Â

Turmeric is one of the most widely used spices in nature. It contains many health benefits that are countless. Chinese medicine has been used in the preparation of various medicines because it contains curcumin. The inhibitory activity of the turmeric extract for the fungus of Candida bicans, which causes oral salivary disease, was compared with the inhibitory effect of some antibiotics against this fungus In this study, isolating and diagnosing this type of fungal disease was obtained by obtaining an oral smear from children with oral diarrhea. Two methods were used to detect the process of inhibition by the alcohol extract of turmeric I was by the method of propagation and the second was using the ts immersed in the extract of the turmeric plant turmeric for 48 hours. The results and the physiological and biochemical tests of the survey used in the study showed that the isolation is due to the yeast of Candida albicans. It was also found that the extract of alcohol for turmeric plant showed an inhibitory effect of the growth of this type of fungus by increasing concentration in both ways. The concentration of 16 mg / ml was found to inhibit the growth of Candida and then 8 mg / ml and finally 4 mg / m compared to the fungal antagonists Nystatin, fluoconazole and ketoconazole It has been shown that turmeric is very useful in the treatment of bacterial and fungal infections and can be counted as an antibiotic because it contains curcumin.Â Â

Published: March 2021

In this study, a hybrid Ant Colony Optimization-Particle Swarm Optimization (ACO-PSO) algorithm was proposed to optimally determine the maximum power point tracking (MPPT) parameters. The main goal of current study is to improve the overall performance of the MPPT system.The efforts of oscillation filtering and noise suppression were taken in this design, as well as the time response and the settling time. The proposed method is employed to track the global MPP under different shadow conditions, based on three different irradiation levels to test the ability and accuracy of the proposed method. The results of tracking MPP by the proposed MPPT technique showed that the improved method tracked the MPP for all the tested cases with a reasonable accuracy and in a very short convergence time as compared to the P&O method.Â Â

Thus, the abstract should be intelligible and complete in it-self (no numerical references); it should not cite figures, tables, or sections of the paper. The abstract should be written using third person instead of first perso The fast microwave assisted pyrolysis (FMWAP) of water hyacinth (WH) for biochar production is investigated. Taguchiâ€™s method was used to optimize FMWAP parameters. The effects of microwave power, temperature, microwave absorber (activated carbon) ratio, and biomass particle size on biochar yield as the response for the process, were studied. The maximum yield was achieved using the optimized conditions of microwave power-994 W; temperature-300Â°C; microwave absorber ratio-0.25; and biomass particle size-0.0315 mm. The reaction time was kept constant at 2 min. The analysis of Signal to Noise ratio (S/N) and variance (ANOVA) were used to identify the effect and the significance of the process parameters on biochar yield. The final results show the significance of all process parameters on biochar yield. The order of significance of these parameters are: microwave power > temperature > microwave absorber > biomass particle size. The produced biochar was analyzed by scanning electron microscopy (SEM) and Energy Dispersive X-Ray Analyzer (EDX). The WH biochar has macroporous and microporous structure and amorphous in nature with some mineral oxides attached to the surface.Â Â

The polymers derived from heterocyclic rings like imidazole was prepared and supported to produce catalytic active supported catalyst. This catalyst was characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), H NMR and UV-visible spectroscopy. The catalyst showed high catalytic activity in the oxidation of cyclohexene and cyclopentene under optimized conditions. In this work cyclohexene and cyclopentene were selected as model alkene for determination the capacity of the prepared imidazole polymer catalyst under optimized conditions of temperature and time of reaction. The catalyst could be readily separated from the catalytic system using uploading 3-5 milligrams of Copper(II), Nickel(II) and Cobalte(II) ions with the surface of polymer the conversion them to nano-particle which are identified by x-ray diffraction. For this research, a statistical method called Response Surface Methodology (RSM) has been used to economize the number of experiments and their meaningful interpretation. The effect of metallated polymer with Copper(II), Nickel(II) and Cobalte(II) were taken to increase the efficiency of oxidation. Optimization results for 0.33 mmole cyclohexene and cyclopentene showed that maximum oxidation efficiency 90. % was achieved at the optimum conditions: catalyst amount 350 mg, temperature 70.0, time 3.30 h and oxidant= 5.25 m mole.Â Â Â
Structural Timber In Compartment Fires – The Timber Charring and Heat Storage Model
Authors: Schmid Joachim , Frangi Andrea 
Published: March 2021

Abstract
The influence of exposed timber surfaces on compartment fires has been well documented in various studies in recent decades. Yet available design concepts still typically neglect the influence of an additional fire load from linear structural timber elements such as beams and columns. As rules for large shares of exposed timber surfaces, e.g. by panels, are rare, authorities and fire safety engineers demand often mock-up compartment fire experiments to estimate the fire safety of a particular design. Such experiments, however, are costly, time consuming, and give limited insights into the potential fire scenarios and may fail to represent properly the fundamental effects arising from exposed structural timber elements in a fire. An approach to overcome these existing limitations is presented, which is able to estimate the contributions from structural timber to a fire from its fully developed- and decay phase until burnout. The model input is developed from an experimental campaign where the relevant effects of fire exposed structural timber could be isolated and measured. It was found that the energy stored in the char layer is a key characteristic for describing the fire dynamics of compartment fires with exposed structural timber. Consequently, the proposed approach describes a framework for the Timber Charring and Heat storage, the TiCHS-model. The validation of the model is shown in this paper by means of existing compartment experiments. A current limitation is the bond line integrity of the fire exposed components as the combustion characteristics of failed char pieces on the floor are currently unknown.
Laboratory studies of the influence of the working position of the passenger vehicle air suspension on the vibration comfort of children transported in the child restraint system

Published: March 2021

AbstractThe article presents the results of laboratory tests on the influence of the choice of the vehicle suspension position and the method of mounting child seats on the vibration comfort of children transported in them. Two child seats were used in the work. The B seat was attached to the vehicle with the ISOfix system, while the A seat was attached in the classic way (with seat belts). During the tests, the values of vertical vibrations were recorded on the seats of child seats, the rear seat of the vehicle and on the basis of ISOfix. The analyzed systems, depending on the method of mounting a child seat, may be characterized by two different vibration transmission chains. They depend on the method of fixing the child seat (the classic way of fixing the seat and the ISOFIX system). The article presents the results of empirical tests carried out at the EUSAMA SA.640 stand, which in these tests acted as a vibration generator with a frequency of 0 to 25 Hz. The analysis of the obtained results confirmed the observations published in previous articles about the negative impact of the use of the ISOfix base on the vibrational comfort of children.
The effects of task types on L2 oral production and learner engagement
Authors: Qiu Xuyan , Cheng Hong 
Published: March 2021

AbstractIn task-based language teaching, various types of tasks are developed from different scenarios in daily communication. Different kinds of tasks encourage oral production of different generic features and can impose different degrees of information-processing pressure on second language (L2) learners. Therefore, the functions and nature of task types are worth considering when designing tasks. Although the effects of task types on L2 oral output have been explored in the current literature, L2 learners’ engagement in different types of tasks is relatively under-explored. Since engaging L2 learners in task performance can facilitate L2 learning, it is important for us to attend to learner engagement in task-based research. This study investigated the effects of two types of tasks, opinion-exchange tasks and storytelling tasks, on the oral performance of 20 English as a foreign language learners in terms of complexity, accuracy, and fluency and their engagement in L2 use. They performed two opinion-exchange tasks and two storytelling tasks. The analysis of their oral discourse revealed that the learners spent longer time, had more turn-taking, and more frequently negotiated language-related issues when co-constructing stories than in opinion-exchange tasks. The results reinforce the importance of considering task types in teaching L2 speaking.
Tracking who knows what: epistemic gaps and the prosodic realization of corrective focus
Authors: Ouyang Iris Chuoying , Kaiser Elsi 
Published: March 2021

AbstractCorrective information is produced with higher prosodic prominence than non-corrective information. However, it remains unclear how corrective prosody is realized in different communicative settings. We conducted two production experiments to investigate whether interlocutors’ prosodic realization of corrective focus depends on each other’s knowledge state. Participants carried out a statement-response task in pairs (e.g., Speaker B:Tina had shrimp at a restaurant. Speaker A:No, she had beef at a restaurant.). Our focus is on the prosody of Speaker A’s utterance. We manipulated whether Speaker B’s statement was implausible in the context (e.g., a context where it is known that Tina actually hates seafood). Furthermore, the two experiments differed in whether Speaker B knew that their statement (e.g., about Tina eating shrimp at a restaurant) was (im)plausible. In Experiment 1, both speakers had access to the crucial context concerning the probability of Speaker A’s statement (Tina’s preferences about food). In Experiment 2, only Speaker A had access to this background information. We found that Speaker A’s prosody when responding to Speaker B was influenced by both (i) the contextual probability of Speaker B’s statements and (ii) Speaker B’s knowledge (or lack thereof) about the contextual probability. We present an analysis where the prosodic prominence associated with corrective information reflects the gap between expectation and reality – in this case, what Speaker A had expected Speaker B to say and what Speaker B actually says.
About the INTER and the INTRA in age-related research: Evidence from a longitudinal CLIL study with dense time serial measurements
Authors: Pfenninger Simone E. 
Published: March 2021

AbstractThis is the first longitudinal study to explore the best time and timing for regular versus bilingual language exposure in (pre)primary programs, using multiple measures over time so as to focus on fluctuations, trends and interactions in individual data as well as intra-individual variation over time. We studied children who had received 50/50 bilingual instruction in German and English (so-called ‘partial CLIL’ programs) as well as children in ‘minimal CLIL’ programs with almost uniquely monolingual German instruction (90% German, 10% English). Results show that, like other individual differences (ID) variables, the age factor behaves like a dynamic entity that changes over time and affects L2 literacy development differentially at different times. Furthermore, while an early age of first bilingual language exposure has no effect on the L2 development for the children in the minimal CLIL program, early-AO bilinguals in the partial CLIL program (age of first exposure 5) outperform the older-AO bilingual group (age of first exposure 7 and 9) in terms of accuracy and (syntactic and morphological) complexity but not in terms of lexical richness and fluency.
