A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...
در مدل سازی مخازن نفتی از دو دسته اطلاعات یکی نمودارهای چاه ودیگری مقاطع لرزه ای استفاده می شود یکی از راه های ایجاد ارتباط و انطباق نمودارها بر مقاطع لرزه ای تبدیل لاگ های پتروفیزیکی به ردلرزه های ژئوفیزیکی است.این کار از راه ساخت لرزه نگاشت های مصنوعی به کمک نمودارهای چگالی و صوتی امکان پذیر است. دراین بررسی با استفاده از اطلاعات چاه های مخزن بنگستان در میدان اهواز واقع در مناطق نفت خیز جنوب...
This Focus Review describes the emerging class of near-infrared (NIR) organic compounds containing the conjugated polyene, polymethine, and donor-acceptor chromophores and exploration of their NIR-absorbing, NIR-fluorescence, and NIR-photosensitizing properties for potential applications in heat absorbers, solar cells, and NIR light-emitting diodes. Examples of NIR organic compounds are reviewe...
Using consensus regions in gene sequences encoding the two forms of nitrite reductase (Nir), a key enzyme in the denitrification pathway, we designed two sets of PCR primers to amplify cd1- and Cu-nir. The primers were evaluated by screening defined denitrifying strains, denitrifying isolates from wastewater treatment plants, and extracts from activated sludge. Sequence relationships of nir gen...
Endoscopic near-infrared (NIR) optical tomography is a novel approach that allows the blood-based high intrinsic optical contrast to be imaged for the detection of cancer in internal organs. In endoscopic NIR tomography, the imaging array is arranged within the interior of the medium as opposed to the exterior as seen in conventional NIR tomography approaches. The source illuminates outward fro...
یک موضعی سازی نخستین از یک کاتگوری همولوژیکی(نیم آبلی)یک زیر کاتگوری بازتابنده کامل منظ است که بازتابش، دنباله های دقیق کوتاه را حفظ می کند. در این پایان نامه عملگر بستار و نظریه تابی در ارتباط با چنین وضعیتی را مطالعه می کنیم. توجه ویژه خود رابه تار و برو بازتابنده منظم معطوف می داریم.
Near-infrared photoimmunotherapy (NIR-PIT) is a highly cell-selective cancer therapy based on an armed antibody conjugated with a phthalocyanine-based photo-absorber, IRDye700DX (IR700). NIR-PIT can quickly kill target cells that express specific proteins on the cellular membrane but only when the antibody-IR700 conjugate binds to the cell membrane and is then exposed to NIR light. NIR-PIT is h...
Near-infrared photoimmunotherapy (NIR-PIT), a promising cancer therapy utilizing an antibody-photoabsorber conjugate (APC) and NIR light, which induces rapid necrotic cell death only in APC-bound cells. Effective NIR-PIT in mouse models has been achieved using superficial light illumination (SLI) with light emitting diodes (LEDs) or lasers, but in the clinical setting, fiber optic diffusers hav...
AIM Triple-negative breast cancer (TNBC) is considered one of the most aggressive subtypes of breast cancer. Near infrared photoimmunotherapy (NIR-PIT) is a cancer treatment that employs an antibody-photosensitizer conjugate (APC) followed by exposure of NIR light for activating selective cytotoxicity on targeted cancer cells and may have application to TNBC. In order to minimize the dose of AP...
Near-infrared (NIR) fluorescent sensors have emerged as promising molecular tools for cancer imaging and detection in living systems. However, cancer NIR fluorescent sensors are very challenging to develop because they are required to exhibit good specificity and low toxicity as an eligible contrast agent. Here, we describe the synthesis of a new heptamethine indocyanine dye (NIR-27) modified w...
