Research Surveys of Electrochemical Sensors for in-situ Determining Hydrogen in Steels

The principle, construction and application of two types of electrochemical sensors-amperometric and potentiometric are surveyed. Both types of sensors are very sensitive to changes in temperature. The accuracy of hydrogen measurement depends on both the precision of sensors developed and the reliable technique of installation and security of sensors. The two types of sensors have been used for in-situ determining hydrogen permeated in steels owing to a corrosive reaction, a hydrogen gas circumstance at elevated temperatures and high pressure or also a pretreatment process such as pickling and plating process, etc.

A PATH ANALYTICAL ANALYSIS OF ORGANIZATIONAL INTEGRATION PRACTICES'EFFECTS ON MANUFACTURING FLEXIBILITY AND COMPETITIVE ADVANTAGF

To cope with an increasingly turbulent environment, manufacturing firms increasingly implement integration practices to enhance flexibility in the production process. This research develops a framework to explore the relationships among organizational integration practices, manufacturing flexibility, and competitive advantage. The study develops valid and reliable instruments to measure these constructs, and it applies structural equation modeling to test relationships among these variables using a large sample. The results indicate strong, positive, and direct relationships between organizational integration practices and manufacturing flexibility, and between manufacturing flexibility and competitive advantage. The results also indicate that organizational integration practices enhance competitive advantage directly as well as indirectly by facilitating manufacturing flexibility.

Clinicians’prescription preferences for treating patients with Alzheimer’s disease in Shanghai

Background:China has more cases of Alzheimer’s disease(AD)than any other country in the world.As training to recognize and manage dementia is in its early stage,it is important to study clinicians’current prescription preferences for treating patients with AD.Methods:This study surveyed neurologists,psychiatrists,and general physicians(GPs)in Shanghai who had outpatients with AD,using a questionnaire asking about their prescription preferences for these patients.Results:Among the 148 clinicians in the study,26.4%were psychiatrists,44.6%were neurologists,and 29.1%were GPs.The groups did not differ significantly in age,gender,or their monthly cases of new patients with mild or moderate AD(P>0.05).Most clinicians prescribed Cholinesterase inhibitors(ChEIs),including Huperzine A,but there were significant group-differences in prescribing specific ChEIs(P<0.05).The daily dosages of ChEI and Memantine prescribed by all three groups were small(P>0.05),and all three groups prescribed piracetam,ergot,and ginkgo biloba drugs.All three groups also tended to treat AD patients with a combination of antidepressants and anxiolytics,although psychiatrists were significantly more likely than neurologists to combine antipsychotics with other drugs(P<0.05).Conclusion:Clinicians in Shanghai prescribed low doses of ChEIs and Memantine for patients with AD.A relatively high proportion also prescribed cognitive enhancers,which lack evidence-based support of their use,and antipsychotics.There is a need for more training about treating patients with AD and for clinicians to standardize their clinical practice.
