The quinones duroquinone (DQ) and coenzyme Q(1) (CoQ(1)) and quinone reductase inhibitors have been used to identify reductases involved in quinone reduction on passage through the pulmonary circulation. In perfused rat lung, NAD(P)H:quinone oxidoreductase 1 (NQO1) was identified as the predominant DQ reductase and NQO1 and mitochondrial complex I as the CoQ(1) reductases. Since inhibitors have...

Previous study has identified that the genetic variants in the human leukocyte antigen (HLA)-DP/DQ region were strongly associated with hepatitis B virus (HBV) infection. But their roles in liver function recovery after hepatic transplantation were still obscure. This study aimed to investigate whether HLA-DP/DQ polymorphisms were associated with post-transplant etiologies and prognosis in Chin...

The coordinate transformation method of asymmetric dual three phase synchronous motor (ADTP-SM) is a Double dq transform using two dq-axes and vector space decomposition (VSD) model the orthogonality ADTP-SM. There are several studies comparing methods in healthy state, but few single-phase open fault state. In healthy, when VSD applied, different harmonic orders current projected onto xy-axes ...

It is intensively discussed in both science and practice how data quality (DQ) can be assured and improved. The growing relevance of DQ has revealed the need for adequate metrics because quantifying DQ is essential for planning quality measures in an economic manner. This paper analyses how DQ can be quantified with respect to the DQ dimension timeliness. Based on an existing approach, we desig...

Nowadays, data plays a key role in organizations, and management of its quality is becoming an essential activity. As part of such required management, organizations need to draw up processes for measuring the data quality (DQ) levels of their organizational units, taking into account the particularities of different scenarios, available resources, and characteristics of the data used in them. ...

BACKGROUND This study compares the longitudinal change of developmental patterns in preschool children with spastic diplegic (SD) and spastic quadriplegic (SQ) cerebral palsy (CP). METHODS Sixty children with spastic CP, aged 1-5 years (3.2 +/- 1.2 years), were classified into 2 groups: SD (n = 29) and SQ (n = 31). Gross Motor Function Classification System (GMFCS) levels were classified duri...

Making sound asset management decisions, such as whether to replace or maintain an ageing underground water pipe, are critical to ensure that organisations maximise the performance of their assets. These decisions are only as good as the data that supports them, and hence many asset management organisations are in desperate need to improve the quality of their data. This paper reviews the key a...

در این پایان نامه، از ترکیب روش های عددی المان محدود و مربعات دیفرانسیلی (dq) به عنوان راه حلی سودمند جهت تحلیل سه بعدی ورق های ضخیم بهره گرفته شده است. تئوری الاستیسیته سه بعدی با فرض کوچک و خطی بودن کرنش ها مبنای این تحلیل قرار گرفته است. در تئوری سه بعدی، بر خلاف تئوری های دو بعدی، هیچ فرض ساده کننده ای درباره تنش و تغییر شکل در ورق در نظر گرفته نمی شود. لازم به ذکر است، معادلات حاکمه به کمک...
