We study the pulse morphologies and pulse amplitudes of thermally emitting neutron stars with ultrastrong magnetic fields. The beaming of the radiation emerging from a magnetar was recently shown to be predominantly non-radial, with a small pencil and a broad fan component. We show that the combination of this radiation pattern with the effects of strong lensing in the gravitational field of th...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

A recent paper described a randomised comparative study of intravenous (IV) pulse methylprednisolone versus infliximab treatment in patients for whom methotrexate treatment had failed. The conclusions that infliximab treatment offered substantial benefits over IV methylprednisolone may be correct, but the design of the trial has resulted in a biased assessment in favour of IV infliximab treatme...

Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...

Background: This randomized, double-blinded clinical study was designed to compare the efficacy and safety of three regimens of intravenous (IV) patient-controlled analgesia (PCA) with remifentanil for postoperative analgesia after laparoscopic-assisted vaginal hysterectomy during the first 24 postoperative hours. Methods: Thirty-four patients were randomly allocated into three groups. The firs...

BACKGROUND Idiopathic membranous nephropathy (IMN) is one of the most common causes of nephrotic syndrome in adults. A proportion of patients will experience spontaneous remission and the decision to offer immunosuppression is guided by the presence of adverse prognostic features. Data relating to the efficacy of different immunosuppressive protocols is lacking, in particular there are little d...

BACKGROUND Parecoxib sodium is the first parenteral COX-2 inhibitor used for pain management licensed for postoperative pain. However, no study has assessed the usage of parecoxib for acute traumatic pain in the emergency department (ED). The objective of this study was to investigate a potential alternative analgesic agent in the ED by determining the mean reduction of pain score between acute...

The performance tests were done for a 1.6 cell s-band BNL-type photocathode RF electron gun, GUN-IV, under a condition of 1.5MW RF power input and 266nm Nd:YAG laser pulse irradiation. As a result, the maximum energy and the maximum charge/ bunch were obtained as 1.6 MeV and 120 pC/bunch, respectively. In addition, a sinusoidal behavior of current with the polarization angle of laser light were...
