In this paper, we apply the Adomian decomposition method for solving Fractional SIR Epidemic Model with Atangana--Baleanu derivative. The existence and uniqueness of the solution are proved. The convergence of the series solution and the error analysis are discussed. Some numerical results are given from solving this model and compering the solution with the fourth order Runge-Kutta method.
The applied research began with the question: What variables will be most beneficial for an empirical database to monitor the professional outcomes and employability of engineers ed-ucated at the Tecnológico Nacional de México, Tijuana Campus (TecNM). After 50 years of edu-cating more than 35,000 graduates, TecNM is uniquely positioned to identify key factors that have impacted engineer graduates’ careers and employment opportunities in Baja California, Mexico. The Fifth Helice Systematic Methodology (also known in Spanish as Quinta Helice Sistemica - QHS Methodology) was used to analyze industry needs, and representatives from government, edu-cation, business, and professional associations, including chambers of commerce, as well as spe-cialized consultants were engaged as sector experts. The preliminary results indicated key vari-ables to include in an electronic survey, which will be circulated among students and graduates of TecNM, and the data gathered will support the development of an online empirical database that will inform strategic decision making at local, regional, and national levels. The conclusions of this research suggested that the information in the database should include factors affecting student drop-out rates, such as connection and a sense of belonging, as well as those impacting employ-ability and professional advancement, such as continuing education and career preparedness.
The high rate of economic growth, the provision of basic facilities, and job creation are products of any nation’s level of industrialisation. Globally, no nation is considered to have attained a concerted level of a high standard of living in the absence of economic development. However, Nigerian industrialisation has continued on a downward journey in the 21st century, despite several industrial development policies. The paper is an attempt to find out how industries have fared and challenges facing their development in Nigeria in the 21st century. It is also an effort to unearth whether UNIDO has influenced Nigeria industrial development. The study adopted a descriptive research design and documentary data analysis method to elucidate the fact that the UNIDO supports have not significantly impacted industrialisation in Nigeria. The adoption of Top-Down as a theoretical model of analyses has validated the fundamental issues raised, informed the findings and subsequent recommendations of this paper.
The pandemic of COVID-19 has spread in almost every country of the world and Pakistan also suffers from this outbreak. Here we design this study to analyze the COVID-19 data of Pakistan to know the epidemic trends of this outbreak in Pakistan. Data for this study is taken from the website of COVID-19 by the Government of Pakistan and the Worldmeter. We analyze the data on the basis of age, gender, provinces/territories and monthly basis. Total COVID-19 cases in Pakistan 281,863, death rate 2.1%, recovery rate 90.8%, mostly people that are dead belonged to the age group 60 to 69 years (29.86%), mostly dead patients were males (74.17%) and COVID-19 has spread in all the provinces/territories. The peak month was June but from July to August 6, 2020 the situation in Pakistan has significantly improved. For more improvement and maintenance, Pakistan must take more sustainable measures.
Response surface methodology (RSM) was used to study the effect of three factors, temperature, yeast addition quantity and time, on the ethanol yield and reducing sugar level in millet rice yellow wine. Seventeen Box–Behnken design (BBD) trials were designed for ethanol yield and reducing sugar level using realistic concentrations of the factors (variables) in millet rice yellow wine. Polynomial regression equations were fitted to experimental data points. The fermentation process was carried out with varied input variables, and all the models showed significant p-values for interaction of variance (<0.05). Millet rice yellow with ethanol yield of 15.68%, v/v was produced at an optimized temperature of 32 °C, yeast addition quantity of 9%, and time of 41 days. The volatile compounds formed in millet rice yellow wine were analyzed by gas chromatography coupled with mass spectrometry (GC-MS). Ten, twelve and sixteen volatile compounds were detected in wines in fermentation time of 41 days, 55 days and 70 days, respectively. The difference in volatile components composition greatly contribute to the flavor of the wine.
COVID-19 is the most serious health concern of the current time which emerged from china and has spread to several other countries across the globe. Besides, millions of deaths, this pandemic has posed the world to multiple problems. Out of which, we seek to investigate the implications and solutions for managing the municipal solid waste and the surges in household waste due to the increased online shopping in response to the current outbreak. In addition, we have discussed two important research questions which will be effectual for the government and waste management officials to effectively manage the municipal solid waste and household waste during the epidemic situation as well as in the normal times.
Insomnia is defined as a complaint of dissatisfaction with the amount or quality of sleep despite adequate opportunity for sleep. In the case of chronic insomnia that the sleep difficulty is present for at least 3 months, it may occurs with the external factors such as stressful or unusual events but persists by internal characteristic factors. Hyperarousal model demonstrates that instability of Sleep-Wake regulation lead to insomnia symptoms and various neurophysiological hyperarousal states. The previous studies have shown that hyperarousal state appearing in chronic insomnia patients are not limited to sleep at nighttime but a stable characteristics that extend into the daytime, in other words ‘24-hour hyperarousal’. However, this phenomenon is mainly measured at bedtime, so it hard to determine whether is maintained throughout 24-hour or just appear at bedtime. The aim of this study is to find the stable pathological characteristics of chronic insomnia by measuring wake state resting EEG (Electroencephalogram) during daytime along with ECG (Electrocardiogram) with chronic insomnia patients (n=24) compared to good sleepers (n=22). Subjects with chronic insomnia showed clearly high frequency band for eyes closed condition in all brain area. And low frequency band at frontal brain area, high frequency band at central and parietal area were found in eyes open condition. Significant higher heart rate also found in chronic insomnia group. These finding showed that individuals with chronic insomnia were in a state of neurophysiological hyperarousal during the most active time in the middle of the day due to abnormal sleep-arousal regulation.
Morphological characteristics of C. cassia Presl (CK) and C. cassia Presl var. macrophyllum Chu (Var) are extremely similar. To achieve a precise distinction, the method to distinguish these two kinds of cinnamon was developed by analyzing the morphological characteristics and microstructures of barks, branches and leaves. Experimental results showed that the distinction of morphological characteristics between CK and Var are mainly on the sprouts color, as well as the section and surface characteristics of barks after they were peeled off. The results of microstructures indicated that the major difference on the anatomical structure of bark is stone cells: CK is arrayed interruptedly, while Var is linked consecutively into intact waveform ring. There are great differences of leaf anatomical structure indexes between Var and CK. Combination of macroscopic and microscopic identification could achieve the goal to distinguish CK and Var accurately, which provides evidence for clear cinnamon distinction.
