The research on the dynamic response and influencing factors of shield tunnel lining under earthquake demonstrates significant engineering value in guiding design antiseismic tunnels. In this paper, a nonlinear finite element model soil-tunnel interaction is established based FLAC difference software, then Mohr–Coulomb elastoplastic plastic damage are used to simulate characteristics soil tunne...

Abstract Sustainability in construction of tunnel is very important to reduce environmental impact and also minimal use earth resources. Therefore, numerical modelling proposing at design stage achieved this objective. To evaluate the changes soil settlements during excavation, empirical, analytical, methods have been frequently applied movement research method effective anticipating possible u...

The routinely used procedure for evaluating tunnel positions following anterior cruciate ligament (ACL) reconstructions based on standard X-ray images is known to pose difficulties in terms of obtaining accurate measures, especially in providing three-dimensional tunnel positions. This is largely due to the variability in individual knee joint pose relative to X-ray plates. Accurate results wer...

BACKGROUND The scope was to review the three main clinical indications in periodontal plastic surgical procedures. AIMS To review the fundamental principles in periodontal plastic surgery, the main surgical designs in flap surgery applied to the treatment of recessions, peri-implant soft tissue deficiencies and soft tissue ridge augmentation, as well as the surgical principles of using autolo...

Agricultural activities in Europe cover half of the total area continent and are simultaneously a cause environmental impact victims same impact. Horticultural or fruit crops considered highly intensive often employ many crop inputs such as fertilizers, pesticides, various materials. Strawberry falls into this group, it has grown acreage production more than others globally. The aim study is to...

Tomato is one of the main vegetable crops in Kuwait with a total greenhouse production of 39,218.3 tonnes and with a value of $ 9.58 million in 2004. Because of the country’s harsh climate, scarce water resources and poor-quality land resources, protected agriculture has a significant role in Kuwait’s agricultural development. Tomato is grown in 25% of total area under greenhouse crops and it p...
