When a pipe roof is used as pre-support for the surrounding rock in shallowly buried tunnel, accurate prediction of support effectiveness important order to ensure rationality structure design. Based on analysis effects, considering construction time structures and interaction mechanisms between steel pipes rock, we establish calculation model pressure acting each semi-circular boundary. Throug...

The present work presents the results of experimental investigation using crushed concrete as recycled coarse aggregates (RCA) and new models hybrid deep beams. Six specimens beams have been tested under static loads: two controls three with different types hybridization for sections (horizontal, curved, arched). This study aims to search optimum distribution such that lowest cost is obtained R...

Methods Nineteen participants with normaland flat-arched feet were recruited for this study (10 with normal and 9 with flat-arched feet). A foot screening protocol comprising measurements from weightbearing antero-posterior and lateral foot radiographs were used to classify foot posture. Tri-planar motion of the tibia, rearfoot and forefoot during barefoot walking were recorded from 10 cameras ...

Laboratory experiments demonstrate high-speed plasma flows from both footpoints of arched magnetic flux tubes, resulting in bulk plasma transport into the flux tube and persistent axial collimation even as the flux tube lengthens and kinks. The measured flows are in agreement with the predictions of hoop force and collimation models involving fundamental MHD forces. These forces are expected to...

In this paper, we discuss issues arising in the construction of cast-in-situ reinforced concrete arched roofs and ways to simplify their design. Despite versatility existing mold systems construction, shell-type roofing structures are entirely different from other structural elements widely used practice terms outline overall dimensions. Therefore, erect them, it is necessary build an individua...

A comparison of 4 × 4 multiple-input multiple-output wireless local area network wireless communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor...

Ciliopathies are a broad class of human disorders with craniofacial dysmorphology as a common feature. Among these is high arched palate, a condition that affects speech and quality of life. Using the ciliopathic Fuz mutant mouse, we find that high arched palate does not, as commonly suggested, arise from midface hypoplasia. Rather, increased neural crest expands the maxillary primordia. In Fuz...

Here we document sexual dimorphism in both external measurements of the head and discrete features of the skull in Apteronotus bonapartii. To quantify morphological variation in A. bonapartii, ten external morphometric measurements were taken from the head and body of 58 individuals. By using Discriminant Function Analysis, we found that the best predictors for distinguishing sexes are the body...

The propositus (Fig. 1) was the result of a 3rd pregnancy of the mother; she had had 2 phenotypically normal children from a previous marriage. The pregnancy was noted for small fetal size, lack of intrauterine movements, and recurrent small antipartum haemorrhages. Urinary oestriol excretion was low throughout the pregnancy. The child was delivered by emergency caesarean section when the mothe...
