The phase behavior of dioleoylphosphatidylethanolamine in aqueous solutions of urea, N,N'-dimethylurea (DMU), and N,N,N',N'-tetramethylurea (TMU) has been characterized by synchrotron X-ray diffraction and differential scanning calorimetry. All three solutes stabilize the lamellar liquid-crystalline phase at the expense of lamellar-gel phase and inverted hexagonal phase of the phospholipid when...

The development of B lymphocytes from progenitor cells is dependent on the expression of a pre-B cell-specific receptor made up by a mu heavy chain associated with the surrogate light chains, immunoglobulin (Ig)alpha, and Igbeta. A variant pre-B cell receptor can be formed in which the mu heavy chain is exchanged for a truncated mu chain denoted Dmu. To investigate the role of this receptor in ...

In this work, an extended evaluation approach for decision making units (DMUs) with a single output is proposed. Firstly, the input and output data for each DMU are changed in the same proportion until all the outputs are equal, and then the coordinate system is established with input i as the ith coordinate axis. Secondly, in the coordinate system, the production possibility set, which is span...

The importance of measuring the efficiency State Madrasah Aliyah in Province Bangka Belitung is at least based on low achievement output or National Examination scores. This shows that implementation terms input and still not efficient. study aims to measure Islands 2017/2018 2018/2020 academic years. research uses a Data Development Analysis (DEA) approach type qualitative with non-parametric ...

this research identifies returns to scale (rts) of efficient decision making units (dmus) with desirable (good) and undesirable (bad) inputs and outputs by presenting a new dea (data envelopment analysis) approach. in this study, we first introduce a new input-output oriented model to determine efficient dmus in the presence of undesirable factors and then, returns to scale of these dmus are es...

<span lang="EN-US">Planning production is an essential component of the decision-making process, which has a direct bearing on effectiveness systems. This study’s objective to investigate efficiency performance units (DMU) in relation planning issues. However, system manufacturing environment frequently subject uncertain situations, such as demand and labor, this can have effect not only ...

The traditional data envelopment analysis (DEA) models treat a decision making unit (DMU) as a “black box”, which is often criticized for not considering the inner production mechanism of a production system. The network DEA models developed to overcome this deficiency by considering the internal structure of a DMU have recently gained popularity. The inner data, however, are not generally avai...

It has been reported that theophylline is primarily metabolized via hepatic CYP1A1/2, 2B1/2, and 3A1/2, and 1,3-dimethyluric acid (1,3-DMU) is primarily formed via CYP1A1/2 in rats. Compared with control rats, the expression of CYP1A subfamily, 2B1/2, and 3A subfamily significantly decreased 24 h (24-h KPLPS rats) after intravenous administration of lipopolysaccharide derived from Klebsiella pn...
