In shield tunnel boring machine constructions, backfill pressure affects surface settlement and the stability of other underground structures nearby.Therefore, it is essential to pre-calculate backfill pressure in the design stage.This study examines and compares the seven internationally known backfill pressure calculation theories and calculates

The eight-year period of the Holy Defense (Iran-Iraq War) is full of successes and failures, bitterness and sweetness.Countless martyrs, warriors and commanders played a role in this field.The history of the imposed war and the holy defense has recorded many of these epic creations.In the meantime, some roles are more prominent and unforgettable.Ac

In this paper, we consider a downlink non-orthogonal multiple access (NOMA) system over Nakagami-m channels.The single-antenna base station serves two single-antenna NOMA users based on statistical channel state information (CSI).We derive the closed-form expression of the exact outage probability under a given decoding order, and we also deduce th

The new fatigue data sheet, No.132, COLOR VITALITY CONDITIONER discloses gigacycle fatigue properties of the A6061-T6 aluminium alloys at high stress ratios.The fatigue tests were conducted mainly by the ultrasonic fatigue testing at 20 kHz, while conventional fatigue tests at 100 Hz were also conducted for comparison.The fatigue test results indic

We present a genome assembly from an individual male Platypus cylindrus (the oak pinhole borer; Arthropoda; Insecta; Coleoptera; Curculionidae).The genome sequence is 147.5 megabases in span.Most of the assembly is scaffolded Perfume, Cologne and Beauty Products into Baby copyright 8 chromosomal pseudomolecules, including the X and Y sex chromosome
