Earthquake science 2015年第1期28卷 87-95页

作者： s.m.talha qadri Bushra Nawaz s.H.sajjad Riaz Ahmad sheikh Department of Earth sciences University of Sargodha College of Earth and Environmental sciences University of the Punjab

Local geology or local site effect is a crucial component while conducting seismic risk assessment studies. Investigations made by utilization of ambient noise are an effective tool for local site estimation. The present study is conducted to perform site response analysis at 13 different sites within urban settlements of Fateh jang area （Pakistan）. The aim of this study was achieved by utilizing Nakamura method or H/V spectral ratio method. some important local site parameters, e.g., the fundamental fre- quencies f0 of soft sediments, amplitudes A0 of corre- sponding H/V spectral ratios, and alluvium thicknesses over 13 sites within the study area, were measured and analyzed. The results show that the study area reflects low fundamental frequency fo. The fundamental frequencies of the sediments are highly variable and lie in a range of 0.6-13.0 Hz. similarly, amplification factors at these sites are in the range of 2.0-4.0.

sex-Dependent Glial signaling in Pathological Pain:Distinct Roles of spinal microglia and Astrocytes

Neuroscience Bulletin 2018年第1期34卷 98-108页

Increasing evidence suggests that spinal micro- glia regulate pathological pain in males. In this study, we investigated the effects of several microglial and astroglial modulators on inflammatory and neuropathic pain follow- ing intrathecal injection in male and female mice. These modulators were the microglial inhibitors minocycline and ZVEID （a caspase-6 inhibitor） and the astroglial inhibitors L-α-aminoadipate （L-AA, an astroglial toxin） and car- benoxolone （a connexin 43 inhibitor）, as well as U0126 （an ERK kinase inhibitor） and D-JNKI-1 （a c-Jun N-terminal kinase inhibitor）. We found that spinal administration of minocycline or ZVEID, or Caspase6 deletion, reduced formalin-induced inflammatory and nerve injury-induced neuropathic pain primarily in male mice. In contrast, intrathecal L-AA reduced neuropathic pain but not inflam- matory pain in both sexes. Intrathecal U0126 and D-JNKI- 1 reduced neuropathic pain in both sexes. Nerve injury caused spinal upregulation of the astroglial markers GFAP and Connexin 43 in both sexes. Collectively, our data confirmed male-dominant microglial signaling but also revealed sex-independent astroglial signaling in the spinal cord in inflammatory and neuropathic pain.

AIm To study the association between vitamin D level and hospitalization rate in Crohn's disease(CD) *** We designed a retrospective cohort study using adult patients(> 19 years) with CD followed for at least one year at our inflammatory bowel disease center. Vitamin D levels were divided into: low mean vitamin D level(m L) vs appropriate mean vitamin D level(30-100 ng/m L). Generalized Poisson Regression models(GPR) for Rate Data were used to estimate partially adjusted and fully adjusted incidence rate ratios(IRR) of hospitalization among CD patients. We also examined IRRs for vitamin D level as a continuous *** Of the 880 CD patients, 196 patients with vitamin D level during the observation period were included. Partially adjusted model demonstrated that CD patients with a low mean vitamin D level were almost twice more likely to be admitted(IRR = 1.76, 95%CI: 1.38-2.24) compared to those with an appropriate vitamin D level. The fully adjusted model confirmed this association(IRR = 1.44, 95%CI: 1.11-1.87). Partially adjusted model with vitamin D level as a continuous variable demonstrated,higher mean vitamin D level was associated with a 3% lower likelihood of admission with every unit(ng/m L) rise in mean vitamin D level(IRR = 0.97, 95%CI: 0.96-0.98). The fully adjusted model confirmed this association(IRR = 0.98, 95%CI: 0.97-0.99). CONCLUsION Normal or adequate vitamin D stores may be protective in the clinical course of CD. However, this role needs to be further characterized and understood.

Run-Up Flow of a maxwell Fluid through a Parallel Plate Channel

引用

American Journal of Computational mathematics 2013年第4期3卷 297-303页

作者： syed Yedulla qadri m. Veera Krishna Department of mathematics Rayalaseema University Kurnool India Department of mathematics St. Josephs PG College Kurnool India

We consider the flow of an incompressible viscous maxwell fluid between two parallel plates, initially induced by a constant pressure gradient. The pressure gradient is withdrawn and the upper plate moves with a uniform velocity while the lower plate continues to be at rest. The arising flow is referred to as run-up flow. The unsteady governing equations are solved as initial value problem using Laplace transform technique. The expression for velocity, shear stresses on both plates and discharge are obtained. The behavior of the velocity, shear stresses and mass flux has been discussed in detail with respect to variations in different governing flow parameters and is presented through graphs.
