مخاطرات طبیعی به عنوان یکی از عوامل مهم پیش روی برنامه ریزان محیطی می باشد. این مخاطرات درمواردی تحت تاثیر عملکرد نادرست انسانی تشدید می شوند، که البته وقوع سیلاب نیز از این پدیدهمستثنی نمی باشد. در این مقاله با توجه به عوامل مختلف موثر اقدام به تعیین مناطق پرمخاطره شده است.البته یکی از عواملی که منجر به بروز خطر سیلاب گردید توسعه مناطق روستایی در حاشیه رودخانه ها وبستر و حواشی دشتهای سیلابی می...

Insulators are defined as a class of regulatory elements that delimit independent transcriptional domains within eukaryotic genomes. The first insulators to be identified were scs and scs', which flank the domain including two heat shock 70 genes. Zw5 and BEAF bind to scs and scs', respectively, and are responsible for the interaction between these insulators. Using the regulatory regions of ye...

حوضه ی آبخیز رازآور در شمال استان کرمانشاه یکی از حوضه­های سیل خیز است که در سال های پرآبی دچار سیل گرفتگی می شود. به منظور بررسی سیل­خیزی حوضه از روش های آنالیز آماری داده های واقعی منطقه، مدل scs و مقطع برداری از رودخانه استفاده شده است. با تقسیم بندی حوضه به واحدهای همگن، عوامل مؤثر بر سیل­­­خیزی مانند پوشش گیاهی، کاربری اراضی، زمان تمرکز، زمان تأخیر، شیب، زمین شناسی، خاک شناسی و شدت بارش مط...

We introduce the nonlinear spin-coherent state (SCS) via its ladder operator formalism and propose a type of nonlinear SCS by the nonlinear time evolution of the SCS. By a new version of spectroscopic squeezing criteria we study the spin squeezing in both the SCS and the nonlinear SCS. The results show that the SCS is not squeezed in the x, y and z directions, and the nonlinear SCS may be squee...

Schwann cells (SCs) express distinct sensory and motor phenotypes, which are associated with modality-specific promotion of axon growth. Here we compared cell proliferation and migration of primary cultured sensory and motor SCs and determined the mRNA expression of several genes, nap1l1, dok4, lpp, mmp-9 and l1cam, in two phenotypes of SCs. The results showed that the rate of cell proliferatio...

A divergent selection experiment in sheep was implemented to study the consequences of log-transformed somatic cell score (SCS)-based selection on resistance to natural intramammary infections. Using dams and progeny-tested rams selected for extreme breeding values for SCS, we created 2 groups of ewes with a strong divergence in SCS of approximately 3 genetic standard deviations. A survey of 84...

Spinal cord stimulation (SCS) applications and technologies are fast advancing. New SCS technologies are being used increasingly in the clinical environment, but often there is a lag period between the clinical application and the publishing of high-quality evidence on safety and efficacy. Recent developments will undoubtedly expand the applicability of SCS, allowing more effective and individu...

OBJECTIVES Spinal cord stimulation (SCS) is an effective method of relieving chronic intractable pain, and one of its key indications is failed back surgery syndrome (FBSS). The objective of the current study was to evaluate the cost effectiveness of 10 kHz high-frequency SCS (HF10 SCS) compared to conventional medical management (CMM), reoperation, and traditional nonrechargeable (TNR-SCS) and...

Purpose To determine the effect of injection volume and formulation of a microneedle injection into the suprachoroidal space (SCS) on SCS thickness and closure kinetics. Methods Microneedle injections containing 25 to 150 μL Hanks' balanced salt solution (HBSS) were performed in the rabbit SCS ex vivo. Distribution of SCS thickness was measured by ultrasonography and three-dimensional (3D) cr...

Spinal cord stimulation (SCS) is a clinical therapy for chronic, neuropathic pain, but an incomplete understanding of the mechanisms underlying SCS contributes to the lack of improvement in SCS efficacy over time. To study the mechanisms underlying SCS, we constructed a biophysically based network model of the dorsal horn circuit consisting of interconnected dorsal horn interneurons and a wide-...
