We have built and tested a mixed signal Multi-Chip Module (MCM) to be used in the Pre-Processor of the ATLAS Level-1 Calorimeter Trigger. The MCM performs high speed digital signal processing on four analogue trigger input signals. Results are transmitted serially at a serial data rate of 800 MBd. Nine chips of different technologies are mounted on a four layer copper substrate. Analogue-to-dig...
UNLABELLED Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest forms of cancer and is very difficult to treat with conventional chemotherapeutic regimens. Gemcitabine and 5-fluorouracil are used in the management of PDAC and act by indirectly blocking replicative forks. However, these drugs are not highly effective at suppressing disease progression, indicating a need for the develo...
DNA replication origins strikingly differ between eukaryotic species and cell types. Origins are localized and can be highly efficient in budding yeast, are randomly located in early fly and frog embryos, which do not transcribe their genomes, and are clustered in broad (10-100 kb) non-transcribed zones, frequently abutting transcribed genes, in mammalian cells. Nonetheless, in all cases, origi...
(الف) در این پژوهش ابتدا کمپلکس های مس (ii) با لیگاند های 2،َ2- بی پیریدین bpy)) و هیستیدین ((his سنتز شدند سپس به همراه cucl2 در نانو راکتور al-mcm-41 و زئولیت- y تثبیت شدند. کمپلکس های تثبیت شده با استفاده از تکنیک پراش اشعه x (xrd) ، جذب و واجذب نیتروژن، جذب اتمی، طیف سنجی ft-irو طیف uv-visشناسایی شدند. فعالیت کاتالیزگری کمپلکس های تثبیت شده در نانوراکتور al-mcm-41 و زئولیت-y در واکنش اکسایش ...
در این پژوهش به منظور حذف کروم از محلول های آبی ماده نانو حفره mcm-41 آمین دار شده با استفاده از روش پیوندزنی پس سنتزی به وسیله گروه 3-آمینوپروپیل تری متوکسی سیلان تولید شد. آنالیزهای پراش پرتو ایکس، جذب- واجذب گاز نیتروژن، وزن سنجی حرارتی و طیف سنجی عبوری مادون قرمز فوریر (ft-ir)، تشکیل ماده میان حفره با ساختار منظم و عامل دار شدن با گروه آمین را تصدیق کرد. nh2-mcm-41 به عنوان جاذب برای حذف یو...
To help us investigate the role of mucin in the protection of the colonic epithelium in the mouse, we aimed to identify the murine colonic mucin (MCM) and its encoding gene. We isolated MCM, raised an anti-MCM antiserum, and studied the biosynthesis of MCM in the gastrointestinal tract. Isolated MCM resembled other mucins in physicochemical properties. Anti-MCM recognized MCM as well as rat and...
Mini-chromosome maintenance (MCM) proteins form complexes that are required for DNA replication and are highly conserved throughout evolution. The replicative helicase of eukaryotic organisms is composed of the six paralogs MCM2-7, which form a heterohexameric ring structure. In contrast, the structure of the archaean replicative MCM helicase is a single Mcm protein that forms a homohexameric c...
Highly dispersed Co particles in MCM-41 were prepared by direct addition of CoCIz to the synthesis gel. The small clusters of Co did not sinter during reduction and sulfidation. Incorporation of Co into the MCM-41 lattice was not observed. The addition of Co to the synthesis gel did not alter the structural characteristics of the MCM-41 samples.
Mesoporous templated MCM-48 silica was prepared using a C16 surfactant as template. The MCM-48 powders and thin films were characterized by different techniques. Two types of porous supports were used, namely macroporous α-alumina and silicon microsieves. The supported MCM-48 layers were applied as liquid permeable membranes in pressure-driven nanofiltration and electric field-mediated ion tran...
Mass customization manufacturing (MCM) has been gaining recognition as an industrial revolution in the 21st century. This paper presents innovative approaches in realizing and exercising MCM in theoretical and practical applications. Strategies of generalized production line platform and modularization are explored to support dynamic reconfigurations of MCM. NIST’s XML-based Shop Data informati...
