The binding domains within a mixed matrix membrane (MMM) that is selective for CO2 comprising MFM-300(Al) and the polymer 6FDA-Durene-DABA have been established via in situ synchrotron IR microspectroscopy. The MOF crystals are fully accessible and play a critical role in the binding of CO2, creating a selective pathway to promote permeation of CO2 within and through the MMM. This study reveals...

The current state of the art Matrix-Matrix-Multiplication (MMM) kernel is known as ATLAS, which generates the best performing MMM code by search. However, today’s computer architecture changes rapidly and it is hard to generate a high performance code without knowing how to use the new instruction sets. Since ATLAS does not make use of blocking for L2 cache, or SSE/SSE2 instruction, we are enco...

فرضیه: جداسازی کربن‌ دی‌اکسید (CO2) از گازهای خروجی دودکش‌ها به‌‌عنوان گاز گلخانه‌ای حاصل از سوختن سوخت‌های فسیلی از دغدغه‌های اصلی در کنترل انتشار گازهای گلخانه‌ای است. از میان فناوری‌های مختلف جداسازی گاز، فناوری غشایی به دلیل مزایای فراوان، توجه بسیاری از پژوهشگران را به خود جلب کرده است.روش‌ها: در این پژوهش، غشاهای آمیخته‌ای جدیدی از پلی(‌اتر-b-‌آمید) (Pebax) به‌عنوان ساختار اسکلتی غشا و گل...

A LTHOUGH myelofibrosis with myeloid metaplasia ( MMM ) was first described nearly one hundred years ago, the etiology of this disturbance remains uncertain.1 Two interpretations have been offered: first, that there is a primary insult to bone marrow resulting in necrosis and necrobiosis followed by a reparative stage of fibrosis of marrow and compensatory cxtramedullary hematopoiesis in the li...

This study compares the clearing and metabolism of three different lipid emulsions. They had the same phospholipid emulsifier and similar particle sizes. In one (LLL) the core component was long-chain triglycerides (TG), the second (MMM/LLL) contained equal molar amounts of medium- and long-chain TG, the third (MLM) contained synthetic TG with medium-chain (M) fatty acids in the 1,3-positions a...

INTRODUCTION Cannabis is the illicit drug mostly widely consumed by adolescents in Spain. The understanding of consumption motives is an important factor for intervention. In Spain, there are no available instruments for their evaluation, hence, the goal of this paper is to study the psychometric properties of the Marihuana Motives Measure (MMM) in a sample of adolescent consumers. MATERIAL A...

غشا در یک فرآیند جداسازی غشایی، قلب فرآیند را تشکیل می دهد. بی شک میزان موفقیت آمیز بودن فرآیند را فاکتورهای توانایی غشا در گذر دادن هر چه بیشتر سازنده ها و نیز گذر دادن گزینشی آن ها، تعیین می کنند. غشاهای ماتریس آمیخته یک نسل نو از غشاها هستند که با امید به کارگیری ویژگی های دلخواه هر دو دسته از غشاهای پلیمری و غیرآلی (همانند زئولیت ها، غربال گرهای مولکولی، نانوذره ها) ساخته شده اند و چشم آن م...

Observing neuronal structures and monitoring changes in synaptic connectivity with respect to time have a significant impact on understanding the basis of structural brain abnormalities and the development of therapeutics for their correction. Today, multiphoton excitation fluorescence microscopy is the method of choice for in vivo neuronal imaging with its inherent 3D resolution, minimal photo...

Multifocal multiphoton microscopy (MMM) enhances imaging speed by parallelization. It is not well understood why the imaging depth of MMM is significantly shorter than conventional single-focus multiphoton microscopy (SMM). In this report, we show that the need for spatially resolved detectors in MMM results in a system that is more sensitive to the scattering of emission photons with reduced i...

A marked metric measure space (mmm-space) is a triple (X , r,μ), where (X , r) is a complete and separable metric space and μ is a probability measure on X × I for some Polish space I of possible marks. We study the space of all (equivalence classes of) marked metric measure spaces for some fixed I . It arises as a state space in the construction of Markov processes which take values in random ...
