The present study was conducted to determine ileal digestible energy (IDE), metabolizable energy (ME), and nitrogen-corrected ME (MEn) contents of expeller- (EECM) and solvent-extracted canola meal (SECM) for broiler chickens using the regression method. Dietary treatments consisted of a corn-soybean meal reference diet and four assay diets prepared by supplementing the reference diet with each...

Multidimensional shearforce-based constant-distance mode scanning electrochemical microscopy (4D SF/CD-SECM) was utilized for the investigation of the activity distribution of oxygen reduction catalysts. Carbon-supported Pt model catalyst powders have been immobilized in recessed microelectrodes and compared to a spot preparation technique. Microcavities serve as platform for the binder-free ca...

Scanning electrochemical microscopy (SECM) is useful in probing and characterizing interfaces at high resolution. In this paper, the general principles of this technique are described and several applications of SECM to biological systems, particularly to living cells, is discussed, along with several example systems. Thiodione was detected and monitored electrochemically during the treatment o...

The morphology of a live cell reflects the organization of the cytoskeleton and the healthy status of the cell. We established a label-free platform for monitoring the changing morphology of live cells in real time based on scanning electrochemical microscopy (SECM). The dynamic morphology of a live human bladder cancer cell (T24) was revealed by time-lapse SECM with dissolved oxygen in the med...

When the export of E. coli SecM is blocked, a 17 amino acid motif near the C terminus of the protein induces a translation arrest from within the ribosome tunnel. Here we used a recently described application of fluorescence resonance energy transfer (FRET) to gain insight into the mechanism of translation arrest. We found that the SecM C terminus adopted a compact conformation upon synthesis o...

SecM in Escherichia coli has two functionally crucial regions. The arrest motif near the C-terminus interacts with the ribosomal exit tunnel to arrest its own translational elongation. The signal sequence at the N-terminus directs the SecM nascent polypeptide to the Sec-mediated export pathway to release the arrested state of translation. Here, we addressed the importance of the central region ...

در مقاله حاضر­ تاثیر رشد بهره وری کل عوامل تولید بخش کشاورزی ایران بر رشد ارزش افزوده و صادرات این بخش در دوره زمانی 1355- 1393 با استفاده از تکنیک هم انباشتگی جوهانسون و الگوی تصحیح خطای برداری (vecm) بررسی شده است. به منظور برآورد بهره­وری مذکور روش حداقل مربعات معمولی و برای بررسی روابط بلند مدت، با توجه به یکسان بودن درجه هم انباشتگی متغیر ها، روش جوهانسون مورد استفاده قرار گرفته است. در ای...
