“…This is consistent with the results of previous research [31][32][33]. In order to understand the deformation of the side wall of many foundation pits, the deformation of side walls of main tunnel and auxiliary tunnel during the construction were calculated [34]. The deformation of the side wall of the main tunnel is shown in Figure 6.…”

Both developing and developed countries are facing a series of difficulties and challenges in the process of urbanization. In recent years, in order to alleviate the problem of urban congestion, underground space has developed rapidly, and the excavation of foundation pit is the most important step in the development of underground space. This paper takes the foundation pit of the tunnel under construction in Suzhou as a research object. The design width of the foundation pit reaches 61.5 m and the depth reaches 18 m, so it belongs to the super wide and deep foundation pit. Numerical analysis is performed by finite element software to calculate the deformation of the foundation pit. The research shows that the main problem to be solved is the deformation of the foundation pit, and the deformation of side wall of foundation pit tunnel is the most obvious. The maximum deformation of the side wall of the main tunnel and the auxiliary tunnel reached the maximum at 15 m. The maximum deformation of the main tunnel is about 1.3 cm, and that of the auxiliary tunnel is about 0.9 cm. Through targeted design and construction, the mechanical performance of the foundation pit retaining structure is optimized, and the stability of the foundation pit is strengthened. The reasonable retaining structure can ensure the good construction quality. The design and construction of the project can provide reference for related engineering construction.

Inflammation is the natural defense mechanism against any external stimuli in the human body and it saves us from foreign entities that may alter our bodies' normal functioning. Any anomaly in this natural defense system leads to the development of different pathological conditions associated with chronic inflammation like rheumatoid arthritis, osteoarthritis, atopy, asthma, allergic rhino-conjunctivitis, coronary artery disease, cardiac arrhythmias, obesity, insulin resistance and type-2 diabetes, depression, and aging. These disorders impair the quality of life of affected people in different ways. Among these, rheumatoid arthritis and osteoarthritis are the most common chronic inflammation-associated disorders. Different therapeutic strategies are already available for the treatment of rheumatoid arthritis and osteoarthritis, but all with pros and cons. Here, we discuss the emergence of several antiarthritic analogs developed by different researchers which could provide the basis for the evolution of newer therapeutic strategies with better activity and safety profiles.

“Pit-in-pit” foundations, where the overall pit is divided into inner and outer pits, present a wide range of engineering problems and yet have received little detailed study. Among the many factors that affect the stability of a deep foundation pit, loading and rainfall are the two most important. Therefore, in this study, physical model experiments are carried out in the laboratory based on a pit-in-pit foundation that is typical of engineering applications in China, simulating the deformation of the system under different loading and rainfall flow conditions. Optical fibers along with constant resistance and large deformation (CRLD) bolts are adopted to collectively monitor the stress and strain inside the pit-in-pit foundation, assisted by fiber Bragg grating (FBG) displacement meters. The results of the monitoring show that the position of the inner pit relative to the outer pit has a strong influence on the stability of the outer pit. The side on which the inner pit is closest to the outer pit wall is the most prone to instability and should thus be reinforced. Comparison and analysis of monitoring results obtained with optical fibers and CRLD bolts allow a potentially dangerous slip surface to be identified, indicating the value of using this type of collective monitoring in deep foundation pits.
