Extraction of “hidden” relaxation times from AC susceptibility data

On the Automatic Extraction of Data from the Hidden Web

An increasing amount of Web data is accessible only by filling out HTML forms to query an underlying data source. While this is most welcome from a user perspective (queries are easy and precise) and from a data management perspective (static pages need not be maintained; databases can be accessed directly), automated agents have greater difficulty accessing data behind forms. In this paper we ...

A Novel Technique for Data Extraction from Hidden Web Databases

Structure based Data Extraction from Hidden Web Sources: A Review

In order to extract data from the web pages of Hidden web sources, many semi-automatic and automatic techniques are proposed based on structure and tags of HTML documents. These

Relaxation times calculated from angular deflections

In this paper we measure the two-body relaxation time from the angular deflection of test particles launched in a rigid configuration of field particles. We find that centrally concentrated configurations have relaxation times that can be shorter than those of the corresponding homogeneous distributions by an order of magnitude or more. For homogeneous distributions we confirm that the relaxati...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
