We present a generalized multivariate seismic event identification method, Regularized Discrimination Analysis (RDA) [Friedman 1989], that can be applied to a large number of regional discriminants. RDA is readily adaptable to an outlier or classical identification approach to regional seismic identification. RDA is designed to address the problems associated with linear (LDA) and quadratic (QD...
Using the recommended daily allowance (RDA) to assess dietary adequacy implies making a direct comparison between RDA and some measure of dietary intake. The value and usefulness of doing so must clearly depend on the limitations of each. By definition the RDA are intended to cover ‘the average amount of the nutrient, which should be provided per head in a group of people if the needs of practi...
The adult RDA is defined as the average daily level of intake sufficient to meet the nutrient requirements of nearly all healthy people. The RDA for protein for adults ≥18 y of age (0.8 g/kg) has been essentially unchanged for >70 y. In practice, the RDA for protein was derived to estimate the minimum amount of protein that must be eaten to avoid a loss of body nitrogen. The Acceptable Macronut...
پوشش گیاهی مهم ترین عامل تأثیرگذار بر پایداری و تعادل اکوسیستم های طبیعی است. روابط بین پوشش گیاهی و عامل های محیطی به شناخت عوامل مؤثر بر رشد و استقرار گونه های گیاهی و هم چنین شناسایی رویشگاه ها کمک می کند. هدف از این بررسی، شناخت این روابط در مراتع منطقه فریدونشهر (حوزه آبخیز سرداب - سیبک) استان اصفهان است. برای این منظور بعد از تیپ بندی پوشش گیاهی به روش فیزیونومیک- فلوریستیک، نمونه برداری ...
OBJECTIVES To compare the dietary intakes of Dutch nutrition and dietetics students with the Dutch RDA and the Dutch National Food Consumption Survey (DNFCS), and to assess whether dietary intake changes during education. DESIGN Cross-sectional and longitudinal research (2004-2010). SETTING Data collection by 7 d dietary record and questionnaire. SUBJECTS Dutch nutrition and dietetics stu...
A new formalism of Resource Driven Automata Nets (RDA-nets) is presented. A RDA-net has two levels: a system level is represented by a net of active resources, describing distribution of agents/resources and their interactions; agents in an object level are finite automata, communicating via ports and shared resources of a system level. RDA-nets are assigned for modeling mobility in multi-agent...
Destructive communication is a problem within the NHS; however previous research has focused on bullying. Rude, dismissive and aggressive (RDA) communication between doctors is a more widespread problem and underinvestigated. We conducted a mixed method study combining a survey and focus groups to describe the extent of RDA communication between doctors, its context and subsequent impact. In to...
Forty patients with "rate dependent aberrancy" (RDA) were studied. This large group of patients permitted a clear definition of the syndromne and recognition of a number of features not previously described. These proved to have a significant bearing on the recognition and differential diagnosis of RDA and non-rate dependent aberrancy. It was found that a small change in cycle length, perhaps t...
این پژوهش به منظور بررسی عامل های محیطی موثر بر پراکنش پوشش گیاهی مراتع زیرکوه شهرستان قاین انجام شد. در این بررسی در آغاز تیپ های گیاهی منطقه شناسایی شد و در منطقه معرف هر تیپ به روش تصادفی- سیستماتیک نمونه برداری انجام گرفت. در درون هر قطعه نمونه پوشش هر گونه با بهره گیری از مقیاس فراوانی - پوشش براون بلانکه ثبت شد. در درون هرقطعه نمونه پروفیل حفر شد و از دو عمق 20-0 سانتی متر و 100-20 سانتی ...
