In order to study the bonding strength of joint surface double-sided laminated shear wall, a wall specimen was designed and fabricated, then bars were planted in precast layer middle post pouring specimen, normal tensile bond tested by drilling core planting bar drawing method. The results show that can be detected method drawing, according cross section sample, it known is indeed weak part mem...

INTRODUCTION Good analgesia is important after a caesarean section but there are no studies to date that compared intrathecal (IT), epidural (EP) and intravenous patient-controlled analgesia (IV PCA) morphine for post-caesarean section analgesia. In this study, we compared the differences in the quality of analgesia and side effects rendered by IT, EP and IV PCA morphine for post-caesarean sect...

We show that for self-adjoint Jacobi matrices and Schrödinger operators, peturbed by dissipative potentials in l(N) and L(0,∞) respectively, the finite section method does not omit any points of the spectrum. In the Schrödinger case two different approaches are presented. Many aspects of the proofs can be expected to carry over to higher dimensions, particularly for a.c. spectrum. This is the a...

BACKGROUND This study aimed to examine whether a mismatch between a woman's preferred and actual mode of delivery increases the risk of post-traumatic stress symptoms after childbirth. METHODS The study sample consisted of 1,700 women scheduled to give birth between 2009 and 2010 at Akershus University Hospital, Norway.
