To achieve the efficient, rapid construction of prestressed anchor cables, in this study, through an indoor pull-out test and field basic test, we investigated mechanical behavior, expansion, drawing performance bond properties a new type high-strength, fast anchorage agent. We analyzed influence water material ratio curing time on its determined corresponding construction. It was found that an...

Article shows shear tests results for anchorage using bent foundation bolts 16, 24 and 36 mm in diameter torque-controlled undercut anchors 12, 16 20 diameter. Load-displacement diagrams were acquired loads static dynamic cyclic uncracked cracked concrete. Cyclic loading pattern simulated seismic on anchors. Shear allowed to estimate influence of cracks strength ductility anchorage.


 The stability of gravity anchorages is critical to the safe operation suspension bridges. purpose this paper study a anchorage under tension main cables. Large-scale load tests and direct shear nature state saturated were carried out in adit at bottom anchorage, because surface below design water level reservoir be built. Representative rock samples area selected for indoor tests. basic ...

Roots reinforce soil by acting as pins, dissipating shear stresses and anchoring the in place. By protruding into binding to particles, root hairs increase root-soil contact aid anchorage. However, it is not yet known whether this ability anchor roots affects system’s soil. Using a laboratory box shearing rig, study explores affect resistance. The force required columns permeated with lacking (...

To address the safety problems caused by clips being squeezed jacks and wire slipping in tensioning process of flat anchorages, we designed a limit plate to be used with anchorage, studied mechanical properties anchorage system after adding through numerical simulation. Lastly, was created applied practical engineering scenario test its performance. The results showed that newly changed butt po...

Cell anchorage is required for cell proliferation of untransformed cells, whereas anchorage-independent growth can be induced by oncogenes and is a hallmark of transformation. Whereas anchorage-dependent control of the progression of the G(1) phase of the cell cycle has been extensively studied, it is less clear whether and how anchorage may control other cell cycle phases and whether oncogenes...

INTRODUCTION The purpose of this study was to compare and measure the amount of anchorage loss with titanium microimplants and conventional molar anchorage during canine retraction. METHODS Subjects for this study comprised 10 orthodontic patients (7 women, 3 men) with a mean age of 19.6 years (range, 18 to 25 years), who had therapeutic extraction of all first premolars. After leveling and a...

Oncogenic K-Ras mutation occurs frequently in several types of cancers, including pancreatic and lung cancers. Tumors with K-Ras mutation are resistant to chemotherapeutic drugs as well as molecular targeting agents. Although numerous approaches are ongoing to find effective ways to treat these tumors, there are still no effective therapies for K-Ras mutant cancer patients. Here we report that ...

Eighty-four mature Norway spruce (Picea abies L. Karst), silver fir (Abies alba Mill) and Scots pine (Pinus sylvestris L.) trees were winched over to determine the maximum resistive turning moment (M(a)) of the root-soil system, the root-soil plate geometry, the azimuthal orientation of root growth, and the occurrence of root rot. The calculation of M(a), based on digital image tracking of stem...
