In this work we address the integration of Engineering Process Control (EPC) and Statistical Process Control (SPC) in complex multivariate scenarios with dynamics (autocorrelation). There are essentially two different integrative approaches: one in which an SPC supervision mechanism is used, without interfering, with an EPC controller active continuously all the time, and another in which the S...
کیفیت، مقوله ای است که امروزه کمتر جمع صنعتی را می یابیم که بدان توجه ننموده و بهای لازم را به آن نداده باشد. در مبحث کنترل کیفیت نمی توان کیفیت را تنها انجام فعالیتهای بازرسی و آزمون در محصول دانست. بلکه محصول باید از ابتدا درست تولید شود. این بدان معنا است که فرآیند تولید باید از ثبات مناسبی برخوردار باشد و کلیه افرادی که به گونه ای با فرآیند سر و کار دارند باید به طور مستمر سعی بر بهبود عملک...
4 Yeast Division of the Centraalbureau voor Schimmelcultures, Julianalaan 67, 2628 BC Delft, The Netherlands The septal pore cap (SPC) of Trichosporon sporotrichoides CBS 8245 is vesiculartubular, connected with flat-tubular endoplasmic reticulum (ER), and stains densely with zinc/iodine/osmium tetroxide, as does the ER. The SPC of Schizophy//um commune CBS 340.81 is more complex, about 600 nm ...
a simple and efficient procedure has been developed for the synthesis of 2,3-dihydroquinazolin-4(1h)-ones derivatives under solvent-free conditions. this method uses the condensation of isatoic anhydride, aldehydes, and amines in the presence of a catalytic amount sulfonated porous carbon (spc). one of the important advantages of the new method is that the spc could be recycled and reused.
The subtilisin-like proprotein convertases (SPCs) are a family of serine proteinases that process secreted proteins at single or paired basic residues. Each SPC has been localized in the rat anterior pituitary, implying their importance in precursor processing in this tissue. The cellular distribution of each SPC has not been established in each hormone-producing cell type. We used double label...
In automatic, retargetable compilation low-cost, analytic cost estimation techniques are crucial in order to e ciently steer the optimization process. Programming models aimed at optimum expressiveness of parallelism, however, are not amenable to static cost estimation. We present a new coordination model, called SPC, that imposes speci c restrictions in the synchronization structures that can ...
The organization of ribosomal protein genes and the gene (fus) for a protein chain elongation factor, EF G, in Escherichia coli were studied with a merodiploid strain that has an episome with genetic markers, ery(r), spc(r), str(r), and fus(r), and a chromosome with markers ery(s), spc(s), str(s), and fus(s). The ery locus determines a 50S ribosomal protein and the spc and str loci determine 30...
Three experiments were conducted to determine standardized ileal digestibility (SID) of CP and AA, DE and ME, and apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in a new source of soy protein concentrate (SPC) and in soybean meal (SBM). In Exp. 1, 9 barrows (initial BW: 13.08 ± 1.98 kg) were prepared with a T-cannula in the distal ileum and allo...
INTRODUCTION SPC-raf and SPC-myc transgenic mice develop disseminated and circumscribed lung adenocarcinoma respectively, allowing for assessment of carcinogenesis and treatment strategies. The purpose of this study was to investigate the technical feasibility, the correlation of initial findings to histology and the administered radiation dose of combined micro-PET/micro-CT in these animal mod...
BACKGROUND AND PURPOSE Myocardial infarction leads to heart failure. Autophagy is excessively activated in myocardial ischemia/reperfusion (I/R) in rats. The aim of this study is to investigate whether the protection of sevoflurane postconditioning (SPC) in myocardial I/R is through restored impaired autophagic flux. METHODS Except for the sham control (SHAM) group, each rat underwent 30 min ...
