Infection with hepatitis viruses, especially HBV and HCV is a global health problem. Inadequacy and inefficiency of immune responses contribute to the chronicity of the diseases and play an important role in the progress of liver injury. This paper aimed to evaluate the frequency of immune cells in the liver of patients infected with HBV and HVC and analysed the correlation between pathological findings and clinical course of the diseases. The currently on going study recruited participants who were 18 years old or older and presented to a tertiary hospital in Surakarta, Indonesia since August 2017. Clinical and laboratory data were extracted from the patients’ medical records. The biopsy procedure was performed on patients’ liver as referred by the doctors who treat them. Samples were sent to the Pathology Anatomy Laboratory for assessment of the disease progression and the evaluation of immune cells in the area of portal triad. An immunohistochemistry staining was conducted to enumerate the frequency of immune cells expressing CD4+, CD8+, CD25+ and Foxp3+ which were associated with the presence of T lymphocytes within the subgroups of T helper, T cytotoxic, and T regulatory cells, respectively. From six liver biopsy samples, we detected one unknown hepatitis case, one case of acute viral hepatitis B, three cases of chronic viral hepatitis B without fibrosis, and one case of chronic viral hepatitis C METAVIR score 1. The frequency of cells expressing CD4+ and CD8+ were predominant (>50%), followed by Foxp3+ expression (26-50%); whereas cells expressing CD25+ were being rarely detected (0-5%). These findings suggest that when the liver injury is minimal, the T helper and cytotoxic lymphocytes are proliferated and activated, which may promote the differentiation of regulatory T cells expressing CD25+ and Foxp3+ to minimize immune-mediated liver damage.

Published: July 2019

Friction stir welding (FSW) is a solid-state joining process that has many advantages including the ability to join high strength alloy as well as dissimilar metals which are hard to be joined by conventional fusion techniques. This welding process involves the penetration of rotating tool which consist of shoulder and prolonged by a pin into a metal plate. The process is followed by advancing speed to weld the metal plate. However, it requires a specialized machine to perform the joining process. A new FSW system including its tools may be costly and thus becomes the main barrier to the development of this FSW process in industry. One of the possible solutions is by adapting the current conventional milling machine with additional rotating and feeding principles to suit the FSW process requirement. In this work, suitable tools, jigs and fixtures for FSW process using conventional milling machine were designed. The design of the tool, jigs and fixtures were fabricated and tested by joining two similar plates of A6061 aluminium alloys. The investigation shows promising results with defect-free welds, good strength and smooth surface finish without gap creation between the welded plates.

Failure detection and diagnosis (FDD) is one of the condition-based maintenance methods. Implementing chiller FDD one could identify the failure and locate where the failure occurs. With the ability to detect and locate the failure, proper maintenance action could be taken to remedy the situation. In most cases, it could restore the performance and extend the useful life of an asset. One of the well-known FDD methods is a Simple Thermodynamic Model (STM). In this paper, a chiller in a commercial building in Jakarta is subjected to the implementation of STM model. The chiller was monitored before and after maintenance. The necessary operating parameters were recorded and processed then they were used to identify two parameters of the STM model by regressing the STM equation. Based on the result, the faults could be detected and located during four different measurements time; on the second month, the eight-month, the eleventh month, and twelfth month. The results show that the STM model is able to detect the faults and locate where the faults have occurred.
