Case Presentations: This retrospective case series describes a cohort of adult patients with terminal stage cancer who were seen between July 1, 2023, and September 25, 2023 and underwent various chemotherapy protocols, which, to our knowledge, represents comprehensive analysis of this patient population. We performed a retrospective search of patients identifying 50 cases of the chemotherapies of patients with cancer and extracted the clinical data via individual chart reviews. At the time of diagnosis, 24 patients were prehydrated with NaCl with KCl prior to the chemotherapy against the tumor, and 26 patients were taking normal saline only before undergoing cancer-specific treatment. Hydration and, prior chemotherapeutic agents use were the most common predepositse. Carcinomatosis peritoneii were the most common signs of the terminal stage of cancer within patients. Twenty-four patients were admitted to the hospital and two received NaCl with KCl hydaration prior to the platinum based chemotherapeutic agent treatment. Twenty-six patients received only normal saline hydration. Conclusion: Our data suggest that NaCl with KCl prehydaration results in better prognosis, including reduced tumor burden or decreased lymph node invasion, when compared to other vulnerable patients populations that receive only normal saline hydration. The graphene exfoliation effect of NaCl with KCl may have contributed to these results.展开更多

People have shown strong interest in travel and other economic activities as they can move freely with the lifting of COVID-19 restrictions. China’s economy is on course for a robust recovery, which was indicated during the Spring Festival holiday on 21-27 January.展开更多

Abstract：
Based on the technique of Dual Mixer Time Difference (DMTD), an 8-channel frequency stabilitymeasurement system has been developed. It realized the measurement of 8-channel 5 MHz and 10 MHz frequencystandards. For 10 MHz frequency, the noise floor is better than 2.0 ×10^(-13)/1 s, 2.5× 10^(-16)/1000 s. It can not only satisfy the internal comparison of time scale ensemble, but also can realize the calibration of normal frequency standards.展开更多

The simple heat treatment greatly improves the hardness, tensile strength and abrasion resistance of medium carbon and high C - low Cr steels. The results indicate that the material removal during abrasion is controlled by a number of factors, such as hardness, chemical composition, microstructure and heat treatment conditions. The conclusion is that the heat treated high C - low Cr steel and mild steel carburized by using coaltar pitch provide the best hardness and abrasion resistance and thus appear to be the most suitable materials for making agricultural tools.展开更多
