Abstract

The purpose of this study is to determine the feasibility of a hyaluronic acid fabrication project by extraction and isolation of the fish eyeball, and we evaluated the results from an engineering and economic perspective. Engineering analysis was analyzed based on tools and raw materials that are available on e-commerce. The economic analysis was done using several economic parameters, such as gross profit margin, the length of time required for an investment to return the total initial expenditure, the condition of a production project in the form of a production function in years, project benefits, and so on. The production of Hyaluronic Acid nanoparticles has good prospects. Technical analysis of producing 50.4 g/L of Hyaluronic Acid nanoparticles per day shows the total cost of the equipment purchased to be 20,726 USD. The investment will be profitable after more than four years and compete with the capital market standard. To ensure the feasibility of a manufacturing project, the project is estimated from ideal conditions to the worst conditions in production activities, including raw materials, utilities, sales, labor, and external conditions. The project is prospective and profitable in the small-scale industry, confirmed by positive values in all economic parameters).

Abstract

Nano MOFs (nMOFs) have now evolved as a new class of MOF with exciting applications. The purpose of this research is to perform bibliometric analysis on nMOFs for medical science by combining mapping analysis using VOSviewer software. Application reference manager used to obtain research data. The data obtained is the result of a search based on the keyword "nano metal-organic framework and madical science". From the search results, 1000 relevant published articles were found in the range of 2017-2021. The results showed that research on nano metal-organic frameworks and medical science has increased in 2017-2020, but it decreases since 2021. The main reason for the increase is the need for human health which continues to increase along with the emergence of new diseases. Although the increase should continue to occur every year, the decline in 2021 is due to social restrictions due to the COVID-19 pandemic, thus limiting the work space in the field of research. This study shows the importance of bibliometric analysis in providing analytical data about what phenomena occur. This research is expected to help and become a reference for researchers in conducting and determining the research theme to be taken.

Abstract

The rapid growth of the human population, industrialization, and urbanization has threatened the global demand for safe drinking water. Water treatment plant plays a vital role in purifying the raw water for consumer use. The typical water treatment process are coagulation-flocculation, sedimentation, and filtration. Among them, the coagulation-flocculation process is the primary stage in the treatment process. This paper reviews and discusses the optimization strategies of a coagulation-flocculation process to enhance overall treatment efficiency. The working principle of the coagulation-flocculation process is first discussed to understand the treatment process better. Next, the importance of aluminum-based coagulants is addressed as chemical coagulants are one of the key factors that can improve the process. The removals of natural organic matter (NOM) by the coagulation-flocculation process were reviewed as NOM normally contributes to the discoloration of water. The optimization of coagulant dosage was also discussed to depict the consequence of uncontrolled dosage. Finally, dosing control strategies in real-time were discussed, namely direct and indirect dosing control.

Abstract

Air pollution is an important issue globally because it is linked to health risks or death as the case may be. No nation has placed a carefree attitude on the menace. Constant monitoring to reduce or bring it to an end is on the increase. Internet of Things (IoT) is one of the tools used in monitoring air quality. The main functionality of IoT includes sensing out the surrounding environment collecting the data from the surrounding and transmitting those data to the remote data centers or the cloud. In this study, Satellite model information provided by Plume Labs, Paris, France was used for the determination of the air quality in four towns (Owerri, Awka, Aba, and Nsukka) in the Southeastern part of Nigeria. The data were obtained from the Plume Labs website between the hours of 6-9 am and 7-9 pm every day for a period of sixty (60 days). The air qualities of the towns were obtained by comparing the satellite results with Plume Air Quality Index Indicator (PAQI). PAQI has seven levels (Low, Moderate, High, Very High, Excessive, Extreme, and Airpocalypse) of pollution which are linked to the World Health Organization (WHO) limits. The results depicted that the air quality of the cities has reached elevated levels of pollution above the 24-hour daily limit set by the WHO, which is an indication that everyone may start to experience serious health effects. A long-term exposure constitutes a real health risk.

Abstract

Oxygen diffusion into the soil ecosystem is imperative for the sustainability of life in the soil. This study evaluated selected microbial exudates as indices of soil respiration in a crude oil polluted soil ecosystem ex-situ using biochemical and physicochemical tools to determine the following parameters; total petroleum hydrocarbon (TPH), dehydrogenases, catalase, ATP, and pH. The result of the study at 1.5 – 3.5% contamination across days-zero to -28 following crude oil impact presented an augmented increase in TPH from 0.02 ± 0.00 to 0.10 ± 0.00 with an increase in the activity of soil dehydrogenases from 4.90 ± 0.01 to 8.80 ± 0.04 katal which was significant (p0.05). Conversely, the activity of soil catalase suffered inhibition from 0.20 ± 0.00 to 0.11 ± 0.00 katal. ATP synthesis decreased from control to 0.24 ± 0.00mg/100g on week one and increased to 0.60 ± 0.10mg/100mg significantly (p0.05) on week four with contamination as the pH was reduced from 5.8 ± 0.00 to 4.1 ± 0.00 significantly, thus creating hypoxia and a reducing environment, a demonstration of soil respiration.

Abstract

This paper presents the bio-generator method for smart farming. Energy harvesting (EH) from the natural environment is becoming widely introduced as a sustainable energy source. Nowadays, smart devices for IoT are critically needed to have an EH type of power supply for continuity of sensing changes. The EH presented in this paper consists of two parts: 1) EH as a supply for sensor nodes for WSNs 2) EH as a sensing module for monitoring soil conditions. The principle of EH is based on the PMFC principle. To evaluate the proposed idea, experiments with avocado trees under different conditions were performed. The harvestable voltage ranges from 0.37 to 0.65 Volts, and the voltage can be converted up to 3.12 Volts using a BQ25504 boost converter. The output voltage of the boost converter is sufficient to supply a sensor node in WSN applications.

Abstract

Polystyrene is one of the many novel materials being developed today. The goal of our research is to demonstrate that polystyrene is a good construction material in the El Oued region of Southeast Algeria. It can also be a strong rival for other building materials like brick. The results of our research, particularly in thermal testing, are very promising. Polystyrene is a better insulator than brick; the temperature of the polystyrene chamber varies between 26 and 27°C, whereas the temperature of the brick chamber varies between 36 and 37 °C. Polystyrene has a 5 times mechanical impact compared to brick. Despite its lack of availability in the region's markets, polystyrene is a strong rival to other materials such as brick.

Abstract

This study aims to demonstrate the electrolyte solution from the fruits to be used as electrical source energy. We combined and varied the composition of the pineapple, squeezed orange, and tomato. The novelties of this research are (1) investigation of the composition of three electrolyte solutions, such as pineapple, squeezed orange, and tomato; (2) the use of these electrolytes. Experiments were done by designing the experimental apparatus and mixing fruits with different compositions. The fruits were mashed using a saw-milling apparatus. We made a series of electrical circuits to test the electrolyte solution. Data were collected every hour for 5 h. We tested the voltage, current strength, and pH. In the circuit, we used a small LED light (2 volts) for ensuring the electrical ability. The results of this study showed the presence of a voltage and current generated, turning on the LED. The more volume of the squeezed orange increased the citric acid, resulting the electrolyte solution to be more acidic (less pH). The utilization of fruits such as pineapple, squeezed orange, and tomato is effective as an electrolyte solution.

Abstract

A data stream is used for handling dynamic databases, in which data can arrive continuously without limit. Association rule mining is a data mining technique, used to find the association between the data items in the databases. To generate association rules, frequent items are to be identified from the transactional database. Normally, in data mining, frequent-item-generation algorithms scan the database multiple times. But this is impossible in data streams because it handles dynamic databases. Hence, there is a need to develop a new algorithm, which reduces the number of database scans. In this work, two new algorithms named Scan-Reduced Indexing and Matrix algorithm are proposed for generating frequent itemsets in data streams. Performances of both algorithms are compared based on the execution time and the number of frequent items generated. Experimental results show that the performance of the Scan-Reduced Indexing algorithm is more efficient than that of the Matrix algorithm.

Abstract

A wind turbine is a machine that converts the kinetic energy of wind into mechanical energy like wind turbines. This mechanical wind power has been used through the ages to pump water or grind grain. Current machines are used to produce wind-type electricity which is consumed locally (isolated sites), or injected into the electricity network (wind turbines connected to the network). In this work, we are only interested in the modelling of a three-bladed horizontal axis wind turbine. All the models were developed by the Matlab/Simulink software, which makes it possible to set up fairly quickly models as well as the associated. The results revealed that the wind profile ranges between 6-7 (m/s), the power coefficient Cp for a pitch angle of =2 has an average value of 0.54 with a relative speed λ value of 6.40, and when the origin of electrical losses is ignored, the electrical power equals the electromagnetic power, and the mechanical speed is stable between (70-80 rd/s).
