the present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. the behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. boundedness and dissipativeness of the system are e...

Aim To compare new remineralizing agents calcium sodium phosphosilicate paste and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste with that of fluoridated toothpaste in remineralization of early carious lesions using scanning electron microscopy and energy-dispersive X-ray (SEM-EDX) analysis. Materials and methods Sixty sound extracted premolars were collected and placed in ...

We investigate the equational theory of several fragments of CCS modulo (strong) bisimilarity with special attention to restriction and relabelling. The largest fragment we consider includes action prefixing, choice, parallel composition without communication, restriction and relabelling. We present a finite equational base (i.e., a finite groundcomplete and omega-complete axiomatisation) for i...

BACKGROUND Acyl carrier protein (ACP) is a fundamental component of fatty acid biosynthesis in which the fatty acid chain is elongated by the fatty acid synthetase system while attached to the 4'-phosphopantetheine prosthetic group (4'-PP) of ACP. Activation of ACP is mediated by holo-acyl carrier protein synthase (ACPS) when ACPS transfers the 4'-PP moiety from coenzyme A (CoA) to Ser36 of apo...

OBJECTIVE The effect of acupuncture (ACP) on regional cerebral blood flow (rCBF) is unclear. Single-photon emission computed tomography studies on three patients with dystonia were performed before and after ACP treatment to test the contention that ACP affects rCBF. METHODS Pre-ACP and post-ACP CBF study were performed on the same day; 99mTc ethyl cysteinate dimer was injected for each study...

BACKGROUND To date, research and promotion regarding advance care planning (ACP) has targeted those with serious illness or the elderly, thereby ignoring healthy young adults. The purpose of this study was to explore young adults' knowledge, attitudes, and preferences regarding advance care planning (ACP) and medical decision-making. Further, we aimed to understand the potential role of public ...

Acyl carrier protein (ACP) contains an essential sulfhydryl group in its phosphopantetheine prosthetic group. We have investigated the state of this sulfhydryl in developing and mature spinach seed (Spinacia oleracea). Seed extracts were separated on sodium dodecyl sulfate or native polyacrylamide gels, blotted to nitrocellulose, and probed with antibodies raised against spinach ACP-I. In extra...

Computation Procedures • Abstract Computation Procedures (ACPs), (Feferman 1992); should have been called Abstract Recursion Procedures. • Here structures are specified by (possibly) manysorted domains, individual constants, partial functions, and partial monotonic functionals of type level 2. ACP Computable Functions and Functionals • The ACP schemata are given by Explicit Definition in type l...

We have characterized the occurrence and expression of multiple acyl carrier protein (ACP) isoforms in Arabidopsis thaliana (L.) Heynh ecotype Columbia. Immunoblot analysis of ACPs from Arabidopsis tissues separated by native polyacrylamide gel electrophoresis and 1 molar urea polyacrylamide gel electrophoresis revealed a complex pattern of multiple ACP isoforms. All tissues examined (leaves, r...

In domains such as factory assembly, it is necessary to assemble many identical instances of a particular product. While modern planners can generate assembly plans for single instances of a complex product, generating plans to manufacture many instances of a product is beyond the capabilities of standard planners. We propose ACP, a system which, given a model of a single instance of a product,...
