Malaysia has witnessed a substantial increase in online purchasing in recent years. The COVID-19 pandemic and the Malaysian government's mobility control order (MCO) have contributed to the rise in online sales. This circumstance has resulted in a substantial increase in the number of packages that Malaysian delivery firms must manage, producing issues for both homeowners and delivery services. Unattended parcel delivery, parcel loss, and unsuccessful delivery efforts have become widespread. This paper proposes an IoT-based Parcel Delivery Alert System to address the challenges associated with unattended parcel delivery, parcel loss, and failed delivery attempts. The system comprises a parcel safe box that integrates with IoT sensors, such as weight and load sensors, image sensors, and light sensors. The IoT sensors provide real-time information about the delivery status and alert the recipient once the delivery has been made. The system's efficiency and effectiveness were evaluated using the MARS simulator, demonstrating a significant improvement in parcel delivery performance. This paper presents the design, development, and simulation of an IoT-based Parcel Delivery Alert System that can enhance the delivery experience while minimizing delivery-related problems. The paper describes the design and development of the parcel safe box and the eventual evolution of the system. One can acquire access to the safe box by scanning the tracking number on the package's delivery label using a QR code.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130498168","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}

Findings revealed the soils are predominantly of sandy silt to clayey silt, silty sand to sandy silt, and sandy clay, with %fines of 48.25, and 51.75 % sand. The depth to basement rock was 22.2 m (avg.), and evidenced of fractured rock at depth range of 9.9 – 26 m. The average static water levels 2.5 m (in well) – 26 m (in borehole). The average values of plasticity index, soaked CBR, group index, unconfined compressive strength, and permeability are 23.9%, 7%, 6, 186.8 KN/m2, and 1.68E-05 cm/s respectively. The recommended minimum thickness of 79 – 140 mm (avg. 109 mm) obtained from design curves will be sufficient for flexible pavement. The average allowable bearing capacity of the soil for square and round foundations varied from 234 – 297 KN/m2 (avg. 268 KN/m2) and 232 – 298 KN/m2 (avg. 268 KN/m2) with estimated total settlement of 17.69 – 18.88 mm (avg. 18.28 mm) for structural pressure of 100 KN/m2. For embankment, the suitability index of the soil suggests a fair/expanding not collapsible construction material. Rocks of igneous and metamorphic rock of high compressive/shear strength, modulus of elasticity, high crushing strength, low deformability, and presumable bearing capacity of 8, 000 – 10, 000 KPa when fresh, and between 5000 – 7000 KPa when slightly weathered. Therefore are valuable as foundation constructions, aggregate in pavement, building stone, and armourstones. The correlation coefficients give between MDD/PI vs. CBR (0.1113), LL vs. coefficient of consolidation (0.0018), PI vs. undrained shear strength/effective overburden (0.0332), PI vs. angle of shearing (0.013), dry density vs. angle of shearing (0.2131), suitability index vs. CBRs (0.3494), clay contents vs. PI (0.422).","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116451026","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}

Its purple pigmented violacein is hypothesised for a broad spectrum of intriguing biological properties, specifically as an antibacterial agent against Gram-negative bacteria. Hence, the current study aimed to isolate, characterise, and review the antimicrobial property of violacein from the Dyh27s2016 strain against P. aeruginosa. The bacterial strain was cultured in nutrient broth with L-tryptophan (0.1 mg/ml); after 24 h, the bacteria were lysed with methanol (3:1 ratio) and mixed with ethyl acetate (4:1 ratio). The top layer was then separated to obtain a concentrated purple pigment. The pH was changed at varying ranges and measured with UV/Vis to characterize this pigment. Then the antimicrobial test was performed against P. aeruginosa using the microdilution method and gauged its minimal inhibitory concentration (MIC). Violacein pigment derived from Chromobacterium violacein was used as a control in all experiments. For the result, crude violacein from Chromobacterium sp. strain Dyh27s2016 was obtained, and the purple pigment in different pH was observed in varying colours; the compound was particularly decolourised at a highly alkaline solution. The pigment was also able to significantly inhibit the growth of P. aeruginosa from 200 µg/mL - 800 µg/mL. Tests show that this pigment has a maximum absorption of light wavelength at approximately 600 nm and antibiotic test results show that the pigment can be considered a potential antimicrobial drug against P. aeruginosa.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122848793","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}

Abuse of antimicrobial leads to the emergence of antimicrobial resistance pathogen. Aim of this research is to screen homologous npcRNAs from known bacteria in C. rodentium, to study the expression of homologous npcRNAs in C. rodentium and to predict the regulatory roles of identified homologous npcRNA in C. rodentium. Firstly, screening for presence of homologous npcRNA in Citrobacter rodentium was conducted by collecting known npcRNAs from S. typhi, E. coli and Y. pestis falling under the same genus of Enterobacteriaceae. Secondly, screening the homolog npcRNA identified from previous step (BLASTn) through Rfam (RNA family) to identify unannotated homologs. Then, target mRNA prediction for homologous npcRNA was done using TargetRNA2 webtool to find the compliment mRNA binding of the homologous sequence and the regulatory activities of this transcript. The npcRNA homologs which predicted to regulate virulence target mRNA were assessed for its expression profile at different growth stages via reverse transcription PCR and the band intensity was quantitatively analysed using Image J tool. The known npcRNA Styr-296 from S. typhi showed expression in C. rodentium during three growth stages (lag, log and stationary). The expression was observed to be high during lag phase followed by no expression during log and stationary phase. This Styr-296 homolog was predicted to regulate mRNA translating modulator drug activity B which is associated with the bacterial virulence. Hence, this is a preliminary study promising for further elucidation of more virulence associated npcRNAs that are yet to be discovered from C. rodentium developing strategy to unveil alternate therapeutic options for diseases caused by this bacterium.","PeriodicalId":407405,"journal":{"name":"Malaysian Journal of Science and Advanced Technology","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124114328","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}
