Um im Wettbewerb zu bestehen, müssen Unternehmen ihre durch Anwendungssysteme (semi-) automatisierten Geschäftsprozesse flexibel ändern können. Hier sind u.a. Workflow-Management-Systeme (WfMSe) in Kombination mit Service-orientierten Architekturen (SOAn) einsetzbar. Das WfMS dient der Steuerung von Service-Aufrufen innerhalb von Geschäftsprozessen. Mittels Geschäftsprozess-Controlling werden P...

Autotransporter biogenesis is dependent upon BamA, a central component of the β-barrel assembly machinery (BAM) complex. In this report, we detail the role of the other BAM components (BamB-E). We identify the importance of BamD in autotransporter biogenesis and show that BamB, BamC, and BamE are not required.

In this paper, a five-neuron bidirectional associative memory (BAM) neural network with two time delays is studied. Since the study of Hopf bifurcation is very important for the design and application of BAM neural networks, we investigate that Hopf bifurcation occurs and a family of periodic solutions appear when the sum of two delays passes through a critical value.

In this paper, a generalized model of bi-directional associative memory (BAM) neural networks delays and impulses is investigated. By constructing suitable Lyapunov functional, Halanaly differential inequality and M -matrix theory, some sufficient conditions for global exponential stability of generalized BAM neural networks with delays and impulses are obtained. An examples are given to show t...

Gene rearrangement studies were performed on blood lymphocytes from eight patients with acute Epstein-Barr virus-induced infectious mononucleosis. The diagnosis in each case was based on characteristic clinical, hematologic, and serologic findings. The blood lymphocytes in each patient consisted predominantly of CD8+ T cells. EBV DNA was detected in seven patients by Southern blot analysis (EBV...

In regenerative tissues, one of the strategies to protect stem cells from genetic aberrations, potentially caused by frequent cell division, is to transiently expand the stem cell daughters before further differentiation. However, failure to exit the transit amplification may lead to overgrowth, and the molecular mechanism governing this regulation remains vague. In a Drosophila mutagenesis scr...

Cancer is a multifactorial disease and hence can be effectively overcome by a multi-constituently therapeutic strategy. Medicinal plant extracts represent a perfect example of such stratagem. However, minimal studies have been done till date that portray the effect of extraction techniques on the phyto-constituent profile of plant extracts and its impact on anticancer activity. In the present s...

BaFe12O19 (BaM) hexaferrite was synthesised through the coprecipitation method. BaFe12O19-activated charcoal-chitosan (BaM-AC-CS) composite ultra-sonication assisted water in oil microemulsion Morphology of BaM hexaferrite, activated charcoal, and BaM-AC-CS powder evaluated using FESEM. The average particle size 60 µm. exhibited a surface area 41.5 m2 g ?1 pore volume 0.041 cm3 g?1. magnetic be...

The adult gonads in both male and female Drosophila melanogaster produce gametes that originate from a regenerative pool of germline stem cells (GSCs). The differentiation programme that produces gametes must be co-ordinated with GSC maintenance and proliferation in order to regulate tissue regeneration. The HOW RNA-binding protein has been shown to maintain mitotic progression of male GSCs and...

In gram-negative bacteria, integral outer membrane β-barrel proteins (OMPs) are assembled by the beta-barrel assembly machine (Bam) complex. The essential components of this complex are the OMP BamA [which contains a carboxyl-terminal β-barrel and an amino-terminal periplasmic module composed of five polypeptide transport associated (POTRA) domains] and the lipoprotein BamD. In Escherichia coli...
