The nitrobenzene hydrogenation process is a highly exothermic reaction which causes the product temperature will increase and then needs to be cooled down with a heat exchanger. The modification process is needed to improve the heat efficiency of the nitrobenzene hydrogenation process by utilizing the heat from reactor product. Heat transfer fluid is used as a medium of heat transfer for both heating and cooling, so that will create a looping heat transfer process. The looping system of heat transfer fluid receives heat from reactor product and then reuses the heat to reheat the recycled hydrogen and for other utilities, so additional energy for these processes is not required. The process modification was simulated using Aspen HYSYS and the comparison of heat efficiency between the basic and the modified process is calculated using the net-energy formula. The results obtained that the net-energy (NE) value for both basic and modified process is 96,714,359.832 kJ/h and 9.869 kJ/h. This shows that the modified process has better energy efficiency compared to the basic process as the net-energy value is closer to zero. Therefore, this modification increases the heat efficiency of the aniline production through nitrobenzene hydrogenation process.

Today, with the development of technology, the concept of the virtual world is gaining more and more importance. "Metaverse", which has become popular in recent years, aims to provide an environment where people can interact, do business, have fun and even live in the digital world. Metaverse, which has become increasingly popular in recent years, offers many different uses in the field of mental health. However, we do not yet have enough information about the effects of this technology on mental health. The effect of Metaverse on mental health has been the subject of many researches that it can be used in areas such as the treatment of psychological disorders, stress reduction, self-confidence, and development of social interaction skills. The biggest advantage of using Metaverse for psychiatric treatment is that the virtual world is separated from the real world. Therefore, the stress, anxiety and other emotional reactions experienced during treatment have no real-life consequences. In addition, the therapist is easier to access in the virtual world and can help patients adapt to treatment more easily. However, the use of Metaverse for psychiatric treatment also has some disadvantages. For example, this method of treatment may be an unrealistic experience for some patients and not effective enough for others. Also, this treatment modality has limited accessibility as it requires high cost equipment and technology. In particular, there has not been enough research on the relationship between the use of Metaverse in the diagnosis and treatment of psychiatric diseases. More research is needed on the effect of Metaverse on mental health. In particular, more studies are needed on its long-term effects and effects on different people. In this review, studies investigating the potential relationship between Metaverse technology and psychiatry and how this technology can be used in the psychiatric field are reviewed.

Violence against women is widely acknowledged as a severe violation of human rights and a significant public health issue with profound physical, mental, sexual, and reproductive health consequences. The purpose of current research is to assess the impact of domestic violence on the emotional states of non-working women. This study, using a cross-sectional quantitative approach, surveyed 350 non-working females in both rural and urban Sialkot through purposive sampling. The sample size was determined using g-power analysis. Findings revealed a strong positive correlation between domestic violence and emotional states (r=.827, p<.001; r=.771, p<.001), suggesting that increased domestic violence severity leads to greater emotional disturbance. The abusive behavior scale (r=.777, p<.001) indicated that marital abuse exacerbates domestic violence, further disturbing emotional states. In conclusion, abusive behavior moderates the relationship between domestic violence and emotional disturbance. Addressing abusive behavior is recommended to mitigate its impact on non-working women's emotional well-being.
