In the current study, oligo(poly(ethylene glycol) fumarate) (OPF)-based hydrogels were tested for the first time as injectable bone substitute materials. The primary feature of the material design was the incorporation of calcium phosphate (CaP) nanoparticles within the polymeric matrix in order to compare the soft tissue response and bone-forming capacity of plain OPF hydrogels with CaP-enrich...

This paper describes an open-flower mutant, designated opf, that we discovered in a genetic screen of fast neutron bombardment mutants in an attempt at floral-dip transformation of Melilotus alba (Fabaceae; white sweetclover), an alternative papilionoid legume host for Sinorhizobium meliloti. The opf mutant developed flowers with reflexed sepals and petals, thereby exposing the stamens and carp...

This paper presents the practical implementation of Phase-Shifting Transformer (PST) model into an Optimal Power Flow (OPF) problem by using the Matlab optimization toolbox. The complexity degree related to the proposed implementation is equivalent to that required by commercial optimization packages for solving optimization models, but with the advantage that Matlab is commonly the available s...

This paper presents the integration of the Voltage Source Converted-High Voltage Direct Current model| (VSCHVDC) into a conventional Optimal Power Flow (OPF) formulation. The assembled VSC-HVDC-OPF model is computationally implemented and solved by using the Matlab ® optimization toolbox. In this sense, the development complexity degree of the proposed implementation is equivalent to that requi...

This paper presents a method in expansion planning of transmission systems using the AC optimal power flow (AC-OPF). The AC-OPF provides a more accurate picture of power flow in the network compared to the DC optimal power flow (DC-OPF) that is usually considered in the literature for transmission expansion planning (TEP). While the AC-OPF-based TEP is a mixed-integer nonlinear programming prob...

This paper introduces the severity of load (SOL) index technique for finding the optimal location of facts devices to achieve the optimal power flow. Objective function in the OPF, that is to be minimised, are overall cost functions which includes the total active power generation cost function. Among various controllers TCPST is considered and optimal location facts device is determined for im...

As part of an extensive research programme to combine the benefits of method engineering and existing object-oriented frameworks (notably the OPF) to create a highly supportive methodological environment for the construction of agent-oriented information systems, we have analysed-hess; contributions to the OPF repository of process components from the Prornertrcus ··agent-mienred methodology. W...

FOREWORD Optimal power flow (OPF) calculations are increasingly critical to modern power systems operationcontrol, markets and planning. However, it is still not easy to obtain reliable OPF solutions that are fully usable in practical power systems engineering. Better methods and software are continually being pursued. This paper discusses some of the calculation and solution requirements from ...

In this study, lignocellulosic biomass from oil palm trunk (OPT) and oil palm frond (OPF) of oil palm tree, Elaeis guineensis, were treated using the microwave-alkali (Mw-A) method, and their chemical constituents, namely cellulose, hemicellulose, and lignin, were analyzed. A number of instruments, i.e. FESEM, FT-IR, and XRD, were employed to analyze the morphology and structural changes of bio...

The ultimate goal of this work was to develop a biocompatible and biomimetic in situ crosslinkable hydrogel scaffold with an instructive capacity for bone regenerative treatment. To this end, synthetic hydrogels were functionalized with two key components of the extracellular matrix of native bone tissue, i.e. the three-amino acid peptide sequence RGD (which is the principal integrin-binding do...
