TECK (thymus-expressed chemokine), a recently described CC chemokine expressed in thymus and small intestine, was found to mediate chemotaxis of human G protein-coupled receptor GPR-9-6/L1.2 transfectants. This activity was blocked by anti-GPR-9-6 monoclonal antibody (mAb) 3C3. GPR-9-6 is expressed on a subset of memory alpha4beta7(high) intestinal trafficking CD4 and CD8 lymphocytes. In additi...
We assess the performance of Ground Penetrating Radar (GPR) method in fractured rock formations very low transmissivity (e.g. T ≈ 10 −9 –10 −10 m 2 /s for sub-mm apertures) and, more specifically, to image fracture widening induced by high-pressure injections. A field-scale experiment was conducted at Äspö Hard Rock Laboratory (Sweden) a tunnel situated 410 depth. The tracer test performed with...
Ground Penetrating Radar (GPR) has been used recently for diagnostics of the railway infrastructure, particularly ballast layer. To overcome fouling, mechanized cleaning process, which increases track occupancy time and cost, is usually used. Hence it crucial significance to identify at stage life cycle, level should be initiated. In present study, a series in situ GPR surveys on selected secti...
DESIGN AND OPTIMIZATION OF UWB ANTENNA FOR AIR COUPLED GPR APPLICATIONS Report Title This thesis presents a novel antenna structure that satisfies the challenging requirements of an air coupled high speed ground penetrating radar (GPR). The desired GPR system is to achieve high spatial resolution and accurate inspection results while scanning at relatively high speed for highway pavement and br...
The Use of GPR and Microwave Tomography for the Assessment of the Internal Structure of Hollow Trees
Internal decays in trees can rapidly escalate into a full decomposition of the inner structural layer, i.e., “heartwood” due to action aggressive diseases and fungal infections. This process leads formation big cavities hollows, which remain surrounded by sapwood layer only. Estimating thickness with high degree accuracy is therefore crucial for correct assessment integrity hollow trees, as wel...
روش رادار نفوذی به زمین (gpr) یک روش ژئوفیزیکی غیر مخرب است که قادر به آشکارسازی انواع ناهمگنی های زیرسطحی و نیز شناسایی انواع اهداف مدفون در اعماق کم است. در پژوهش حاضر مدل سازی پیشرو و وارون داده های gpr با هدف کاربرد در زمینه باستان شناسی، انجام شده است. منطقه مورد مطالعه، منطقه باستانی تپه حصار دامغان است که در این منطقه با هدف بررسی های باستان شناسی زیرسطحی، تعدادی پروفیل gpr با استفاده از...
Cell divisions are sometimes oriented by extrinsic signals, by mechanisms that are poorly understood. Proteins containing TPR and GoLoco-domains (C. elegans GPR-1/2, Drosophila Pins, vertebrate LGN and AGS3) are candidates for mediating mitotic spindle orientation by extrinsic signals, but the mechanisms by which TPR-GoLoco proteins may localize in response to extrinsic cues are not well define...
Cytokinesis and spindle positioning require the cortical force regulator G Protein Regulator 1/2 (GPR-1/2). GPR-1/2 is thought to localize to sites of cortical force generation. Does GPR-1/2 also act as a sensor for mechanical stimulation? I mechanically stimulated the cortex by indenting it with a glass needle and observed the cortical localization of a YFP::GPR-1 transgene. I found that corti...
Dating back to as far as 1940, the US road and bridge infrastructure system has garnered quite the status for strategically connecting together half a continent. As monumental as the infrastructure’s status, is its rate of deterioration, with the average bridge age coming at a disconcerting 50 years. Aside from visual inspection, a battery of non-destructive tests were developed to conduct stru...
