Additionally, we identified three potential probiotic bacteria - Bacillus subtilis, Lactobacillus spp., and Enterobacter aerogenes. These probiotics can enhance immunity, support survival, and have minimal environmental impact. Shrimp and prawn farms in Bangladesh may be susceptible to harmful microorganisms due to contaminated water sources and subpar sanitation during post-harvest handling and processing.

ChrDD refers to the method that is widely used to attain the in vivo drug availability to match up with the circadian cycle of the human being to overcome the side effects of the drugs and enhance or optimize the therapeutic effect of the drugs. The circadian rhythms of the human body fluctuate from time to time during the day, as is well-known. So, for the treatment of such diseases, this method is widely used. Nowadays this method is widely accepted by pharmaceutical companies to minimize the dosing frequencies, toxicity, and drug delivery to treat particular diseases that perfectly match the circadian cycle when the symptoms get maximum to worse condition. These drugs are frequently used to treat conditions like cardiovascular disease, asthma, arthritis, ulcers, diabetes, and more that affect circadian rhythms. They offer the patient who is afflicted with these conditions the greatest advantages and facilitate compliance with the dosage form. In any disease, if there is any variation in circadian rhythms, the drug release also varies to overcome the symptoms of the disease.","PeriodicalId":509211,"journal":{"name":"Suranaree Journal of Science and Technology","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140684537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve the best results when making decisions, optimization procedures like particle swarm optimization (PSO), ant colony optimization (ACO), and mean variance optimization (MVO) have been widely used. However, these optimization algorithms have a number of drawbacks. For example, the ACO-based solution does not support application complexity, while PSO exhibits a low rate of convergence throughout the course of the process cycles. In this work, a hybrid approach for the design of microstrip antennas has been suggested by integrating PSO and MVO techniques, which greatly improves the outcomes, taking into account the limits of existing optimization processes. The proposed hybrid approach is capable of combining the PSO-MVO with multiple parameters like iteration, upper bond, lower bond, and objective function. Finally, research work evaluates the time consumption and error rate with respect to conventional techniques. Results show an improvement of 61% and 50% in the time consumed by the hybrid PSO-MVO approach as compared to the PSO and MVO approach respectively. The hybrid PSO-MVO achieves an accuracy of 87.15 which is 3% better than individual optimization techniques. Simulation work has been made in a Matlab environment in order to get the best solution using a hybrid optimization technique.","PeriodicalId":509211,"journal":{"name":"Suranaree Journal of Science and Technology","volume":" 53","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140683839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to an extraordinary rise in nonlinear loads, such as power electronic-based loads, the issues with power quality in distribution systems have become severe. Non-sinusoidal current is drawn from the electric grid by the nonlinear loads. These non-sinusoidal currents contain harmonics and reactive power that lower the system’s overall PQ. Unified Power Quality Conditioner (UPQC) was emerged as a promising compensator to provide a solution for all PQ issues. UPQC generally had two Voltage Source Converters (VSC), one was Shunt, and the second was a Series that act as a current controller and voltage controller, respectively. Yet the controlling strategy of this compensator was still complex to design. Here, an optimization based Fractional Order Proportional Integral Derivative (FOPID) was developed to manage UPQC for improving PQ in a hybrid Renewable Energy System (RES). The optimal problem of the FOPID controller was solved through the use of a novel optimization approach. The pulse signal of UPQC was done using the optimal controller, which analyzes the error value of reference voltage and actual load voltage to generate pulses. The proposed optimal controller based UPQC performance was validated under various conditions such as interruption, swell, harmonics, and sag. The optimal controller offered THD value in sag, swell, and interruption period at current have 10.19%, 9.77%, and 10.09%, at voltage have 0.09%, 0.07%, and 0.30%. Moreover, the issues mitigation performance was compared to another present approaches. The validated outcome demonstrates the proposed model provides a well mitigation performance in all PQ issues conditions, so it was well fit for real-time implementation.","PeriodicalId":509211,"journal":{"name":"Suranaree Journal of Science and Technology","volume":" 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140684859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Inverted-T Junctionless (ITJL) FET features a multi-fin architecture that utilizes the unused space within the fins and combines it with the junctionless topology, maintaining the same doping concentration from source to drain. In order to mitigate the short channel effects and overcome the fabrication challenges, an inverted-T FET has been designed. The crucial performance parameters of device are explored by varying the geometric dimensions and process parameters. The performance of ITJLFET is measured by varying different parameters namely temperature (T), doping concentration (Nd), work function 𝒎 ), and dielectric constant (K) at 30-nm technology node and effect of geometric variations are measured by altering the gate length (Lg) and oxide thickness (Tox). Inverted-T junctionless field effect transistor (ITJLFET) is designed with different gate lengths in the range of 14 nm to 30 nm and shows the improvement in ION by 64% as compared to the conventional JLFET. The parametric analysis like transfer characteristics (Id-Vgs), Ion/IOFF ratio, subthreshold swing (SS), drain induced barrier lowering (DIBL) and gate capacitance (Cgg) are investigated for 250 K to 350 K. From the results, it is perceived that temperature has less effect on the Inverted-T junctionless transistor performance. The cut-off frequency for the designed device is calculated and observed to be in the range of 0.3 to 1.5 THz. Hence, device can be used for high-frequency applications at the submicron regime.","PeriodicalId":509211,"journal":{"name":"Suranaree Journal of Science and Technology","volume":"15 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140442980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
