Measurements were made of the femoral shaft/neck angle (CCD angle) in 106 human foetuses, aged from 16 to 38 hbd, using a "FEM-GEO_03" computer program. The values of the CCD angle in the group under examination were: mean = 140.48 degrees, SD = 6.95 degrees, max = 157.90 degrees, min = 113.93 degrees. No significant differences were found in CCD angle size between male and female foetuses or b...
Based on the principle of CCD vertical target measurement system, this article researched the factors of the CCD camera that affects the target detection performance , including CCD sensitivity and exposure, background illumination and target illumination, CCD distinguish ability, contrast between background and objectives and gave the relevant calculation methods. Through theoretical analysis,...
فرض کنیم g گروهی متناهی,irr(g)مجموعه تمام سرشتهای تحویل ناپذیر (مختلط)g و cd(g)مجموعه درجات آنها باشد.موضوع اصلی این پایان نامه مطالعه گروههایی مانند g است که برای آنها cd(g)یا cd(g-1) مجموعهای از اعداد صحیح مثبت متوالی باشند.جنین گروههایی ,ccd-گروه نام دارد.بخصوص نشان می دهیم که اگر cd(g)={1,2,..k}آنگاه k<4 و g حلپذیر است یا k=6 و g زیرگروهی جون h داردکه(2,5)h?sl و g=hz(g.)
در این پژوهش ابتدا،سنتز نانو ذراتca(oh)2 به روش رسوب دهی انجام و سپس ماده ی سنتز شده در ساخت پایه کاشتنی دندانی از جنس نانوکامپوزیت تیتانیم/هیدروکسی آپاتیت استفاده شد. مواد مورد استفاده در این تحقیق شامل نیترات کلسیم آبدار، هیدروکسید سدیم، آب و نیز الکل بود. برای انجام فرایند، پارامترهای دما، نسبت وزنی نیترات کلسیم به سود و درصد الکل در پنج سطح مختلف در نظر گرفته شدند. با استفاده از روش طراحی آ...
the effect of the operating conditions (temperature, time, ph, enzyme level and pulp consistency) used in the enzymatic step of a xp (cartazyme-hydrogen peroxide) sequence for bleaching kraft pulp from bagasse on various properties of the resulting pulp and paper sheet products was studied. the quality of bagasse used, was examined by its yield, brightness,viscosity and the kappa number. finall...
For wider include of CCD camera to industrial production as measurement device at present time defend mainly resolution of used CCD elements and for highresolution elements their price. At our department we developed the methods which allow to mathematically increasing the resolution of these CCD cameras.
A CCD imaging system has been developed for precision laser beam pointing. The systcm contains a high frame rate CCD camera operated in windowing mode under command of an ernbeddcd processor. A ltiser pointing and tracking update rate of 2 KIIz has been achieved. Subject terms: CCD cameras, laser pointing, laser communications.
Abstract Controlled molecular transport and separation is of significant importance in various applications. In this work, we presented a novel concept nanofluidic charge-coupled device (CCD) for controlled DNA separation. By leveraging the unique field-effect coupling systems, CCD aims to store charged biomolecules such as DNAs discrete regions nanochannels transfer separate these charge packe...
Objective The purpose of this study is to investigate predictors of crossed cerebellar diaschisis (CCD), and the effects of CCD on functional outcomes including motor function, activities of daily living, cognitive function, and ambulation 6 months after onset in patients with intracerebral hemorrhage (ICH). Methods A total of 74 patients experiencing their first ICH were recruited. If the as...
A chronic compression of the dorsal root ganglion (CCD) produces ipsilateral cutaneous hyperalgesia that is associated with an increased excitability of neuronal somata in the compressed ganglion, as evidenced by spontaneous activity and a lower rheobase. We searched for differences in the properties of voltage-gated Na+ and K+ currents between somata of CCD- and control (unoperated) rats. CCD ...
