The aim of this paper is to present results of testing a full scale reinforced concrete T connection by static loading. The connection is a T connection representing a beam-column connection. The beam and column had a square cross section with a 300 mm dimension. The height of the column was 2.9 m and the clear beam length was 1.4 m. The connection was initially tested to failure. Galvanised st...
The ethyl acetate extract of the roots of Moutabea guianensis gave 1,6-dihydroxy-4,7,8-trimethoxy-9H-xanthen-9-one (1), a new xanthone. The isolation was accomplished by column chromatography on silica gel and the structural elucidation of this compound was established by spectroscopic analyses including 1D and 2D NMR and HRESIMS.
The first molded gas chromatography (GC) microcolumn is described. This microcolumn consists of a single microtextured thermoset polymer composite which acts as both the structural material and the stationary phase. The resultant microcolumn is inexpensive and has been coupled to a disposable colorimetric sensor array, creating a disposable column-detector unit and demonstrating a proof of conc...
Understand the Toll plaza structure for TCB III. In this we have mainly designed two structural members i. e. Column and Purlin. The design of member is conducted both manually using Staad pro software then compared results.
The reaction of ortho-lithiated aryloxiranes with various enaminones straightforwardly affords new functionalized isochromanes as mixtures of two epimeric stereoisomers in reasonable to very good yields (50-90%). The two diastereomers, which show a high structural variability, can be easily separated by column chromatography.
In vitro protein refolding is still a bottleneck in both structural biology and in the development of new biopharmaceuticals, especially for commercially important polypeptides that are overexpressed in Escherichia coli. This review focuses on protein refolding methods based on column procedures because recent advances in chromatographic refolding have shown promising results.
همواره کاهش مصزف انرژی در برج های تقطیر، یکی از مشکلات صنایع شیمیایی بوده است. اگرچه روش های متعددی جهت انتگراسیون انرژی برج های تقطیر پیشنهاد گردیده اند ولی اکثرا به علت مشکلات طراحی و کنترلی استفاده نمی شوند. در این پروژه، دو آرایش برج تقطیر با انتگراسیون انرژی شامل برج تقطیر با تراکم مجدد بخار(vapor recompression column)یا vrcو برج تقطیر با تبخیر ناگهانی در جوش آور(reboiler flashing column)ی...
The aim of this study was to compare structural differences in the nirS-type denitrifying microbial communities along the environmental gradients observed in the water column and coastal sediments of the Baltic Sea. To link community structure and environmental gradients, denitrifier communities were analyzed by terminal restriction fragment length polymorphism (T-RFLP) based on nirS as a funct...
The principal objective for this work was to extend the field of application FEM space frame beam-column connections under static loading and with lateral displacements. A four-storey building modelled load condition. Horizontal vertical structural elements were designed according Eurocode 2. In order understand behavior external node made by column, two beam upper models using correct boundary...
The construction methods currently adopted for multi-story concrete buildings resorts the strategy to cast columns and slabs with high normal compressive strength, respectively. intersection region affects load transfer performance of columns, causing expressive confinement stress in interior columns. However, when is only provided by two sides, as corner it not enough increase lateral stress. ...
