Atorvastatin calcium is a potent active pharmaceutical ingredient that reduces blood cholesterol levels. However, oral bioavailability is low because it is difficult to dissolve in water. Therefore, further research to increase the solubility of the drug is needed to improve its bioavailability properties. This research aimed to increase the solubility of atorvastatin calcium through the formation of a multi-component solid. Furthermore, the drug was formed into a multi-component solid with dipicolinic acid as a coformer using the solvent evaporation-quenching method. A powder X-ray diffractometer (PXRD), Fourier transform infrared (FTIR) spectrometer, differential scanning calorimeter (DSC), and scanning electron microscope (SEM) was used to characterize the solid. Also, the shake-flask method was used to analyze the solubility of the solid in distilled water. The results showed that atorvastatin calcium and dipicolinic acid formed a new multi-component solid of cocrystal type. The solubility of the atorvastatin calcium from the multi-component solid was 344.31 ± 37.09 mg/L, which was a significant increase of about 2.7-fold compared to the pure form.","PeriodicalId":50285,"journal":{"name":"International Journal of Technology Management","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88552055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts to utilize and improve the value of pulp waste have been done by using primary sludge (still containing cellulose) and fly ash as a filler to produce composite foam polystyrene (PS)- based as sound absorbent. In this study, the composite foam was produced by mixing primary sludge and fly ash with several compositions such as PS, PS/PS-g-MA/primary sludge/fly ash (80/10/10/0), (80/10/7/3), (80/10/5/5), (75/10/10/5), and (75/10/12/3). The composite was characterized based on ISO 11654:1997, mechanical properties, thermal analysis using TGA and DSC, morphology using SEM, crystallinity using XRD, and chemical analysis using FTIR. The results showed that the band at 1600.63 cm -1 was sharper due to a chemical reaction being formed between PS, primary sludge, and fly ash. The XRD analysis showed a new diffraction peak in the 2  = 21-24 o . The morphology analysis showed that primary sludge and fly ash were uniformly dispersed into PS, increasing the mechanical properties and decreasing the melting point of the PS foam composite. The sound-absorbing composite produced had qualified ISO 11654:1997 on the rating level of the sound absorption coefficient on materials for rooms with sound absorption classes D and C with the value of  w 0.328-0.793.","PeriodicalId":50285,"journal":{"name":"International Journal of Technology Management","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76550949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anomaly detection (AD) is a solution for cellular operators to overcome the difficulty of quality control over the proliferation of cellular phone usage. The telecommunications network monitoring system with anomaly detection enables immediate discovery of problems before they become more complex. Monitoring activities produce logs, which are then analyzed according to the interest, often with the help of statistics and visualizations. Relying on humans for analysis is increasingly difficult due to the immense amount of logs in modern telecommunication networks. This work extends the monitoring to automated anomaly detection by using various ELK modules to form an intelligent monitoring system. A testbed based on OpenAirInterface (OAI) and USRP B210 radiohead is used, which includes the functionalities of HSS, MME, SGW, PGW, eNB, and UE. The proposed system has an average accuracy of 91.5%. This is supported by an average value of the proportion of normal conditions that are correctly predicted at 99.31%. On the other hand, the system can still maintain the functionality of the cellular telecommunications network with an excellent predicate on service quality.","PeriodicalId":50285,"journal":{"name":"International Journal of Technology Management","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87760510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
