Synchrotron radiation X-ray imaging technique was applied for in situ observation of Cu6Sn5 intermetallic compounds (IMC) growth Sn/Cu and Sn-3.5Ag/Cu joints under isothermal temperature conditions 250/300/350 °C time duration 1.5 h. The IMC Sn-Ag solder characterized by the formation grooves during interfacial reaction, this can be attributed to Ag content. Kinetically, rate constants height w...

  Data envelopment analysis (DEA) is a nonparametric approach to evaluate theefficiency of decision making units (DMU) using mathematical programmingtechniques. Almost, all of the previous researches in stochastic DEA have been usedthe stochastic data when the inputs and outputs are normally distributed. But, thisassumption may not be true in practice. Therefore, using a normal distribution wi...

Parkinson's disease (PD) is characterized by loss of dopaminergic neurons in the substantia nigra (SN), the cause of which is unknown. Characterization of early SN pathology could prove beneficial in the treatment and diagnosis of PD. The present study shows that with the use of short-echo (5 ms) Stimulated-Echo Acquisition Mode (STEAM) spectroscopy and LCModel, a neurochemical profile consisti...

the ratio of cd4+/cd8+ has been used as a clinically index to evaluate patients' immunity. numerous researchers have studied cd4+/cd8+ ratio in pulmonary tuberculosis (ptb) patients. however, the change of cd4+/cd8+ ratio remains controversial. we present a meta-analysis of 15 case-control studies to identify the change of cd4+/cd8+ ratio in ptb patients.we assessed heterogeneity of effect esti...

The anticancer prodrug, irinotecan, is converted to its active form 7-ethyl-10-hydroxycamptothecin (SN-38) by carboxylesterases, and SN-38 is inactivated by UDP-glucuronosyltransferase (UGT)1A1-mediated glucuronidation. UGT1A9 also mediates this reaction. In a recent study, it was reported that the UGT1A9 IVS1+399 (I399)C>T polymorphism is associated with increased SN-38 glucuronidation both in...

Subcellular fractionation of human brain cortex obtained at autopsy yielded microsomal and synaptosome-rich fractions from the gray matter and microsomal and purified myelin fractions from the white matter. The phospholipids of myelin were high in plasmalogens, and the molar ratio of alkenyl acyl sn-glycero-3-phosphorylethanolamine to diacyl sn-glycero-3-phosphorylethanolamine was 4. The acyl g...

Individual subjects' performance was examined for cross-modality matching (CMM) of loudness to visual area, as well as for magnitude estimation (ME) of the component continua. Average exponents of power functions relating response magnitude to stimulus intensity were .73 for area, .20 for loudness, and 2.44 for CMM. Predictions of the CMM exponent based on ME were higher than the empirical valu...

Tin-doped indium oxide (ITO) films with Sn/In atomic ratios in the range 0-0.1 were synthesized by electrochemically assisted deposition (EAD). The process involves a fast one-step cathodic deposition of a highly crystalline In-Sn hydroxide (InSnOH) film followed by thermal conversion into ITO at 300 C. The cathodic precipitation of InSnOH is preceded by formation of an In-Sn complex in solutio...
