A putative capsular polysaccharide containing D-rhamnose was isolated from the phytopathogenic bacterium Burkholderia gladioli pv. agaricicola by phenol/water extraction followed by ultracentrifugation of the separated water phase and gel-permeation chromatography of the thus obtained supernatant. By means of chemical analyses and NMR spectroscopy, the repeating unit of the polymer was shown to...

The retail price a household pays for the last unit of grid-supplied electricity consumed is an important driver of the decision to install a rooftop solar photovoltaic (PV) system. This price is the cost a household avoids by consuming a kilowatt-hour (KWh) from their rooftop solar system. Consequently, if the levelized cost of a KWh from a rooftop solar system is less than this retail price, ...

Maximum power point tracking (MPPT) of a photo voltaic system with different temperature and insolation conditions used for Micro grids can be explained in this paper. The micro grid conception permits small distributed energy resources (DERs) to act during a coordinated manner to produce a necessary quantity of active power and supportive service once needed. This paper proposes an approach of...

Nowadays, computer modeling provides a fantastic tool to decrease cost, optimize design, and reduce turnaround times of any product. Analysis of microelectronic and photonic structure – 1D (AMPS-1D) presents one of many attempts to unite numerical modeling and the physics of photovoltaic (PV) cell into one software package where the PV device model appears as a planar, layer-by-layer cell. This...

The growing penetration of solar photovoltaic (PV) systems requires a fundamental understanding of its impact at a system-level. Furthermore, distributed energy storage (DES) technologies, such as batteries, are attracting great interest owing to their ability to provide support to systems with large-scale renewable generation, such as PV. In this light, the system-level impacts of PV and DES a...

OBJECTIVE We sought to determine whether novel approaches to volumetric assessment of the early placenta can yield significant predictors of adverse outcome. METHODS We measured placental volume (PV) at 11 to 14 weeks using virtual organ computer-aided analysis and normalized the PV to the crown-rump length (CRL) to yield the placental quotient (PQ = PV/CRL). We also calculated the mean place...

The increasing number of electricity consumers results in power quality problems the distribution system. Solar photovoltaic integrated unified conditioner (UPQC-PV) is a widely adopted device that can improve system's voltage and current quality. This paper presents an optimal design performance analysis with double-stage solar system (UPQC-PV). A technique based on sequence component detectio...

Wound measurement is an objective and direct way to trace the course of wound healing and to evaluate therapeutic efficacy. Nevertheless, the accuracy and efficiency of the current measurement methods need to be improved. Taking the advantages of reliability of transparency tracing and the accuracy of computer-aided digital imaging, a transparency-based digital imaging approach is established, ...

The increase in penetration of large-scale renewable generation significantly affects power system characteristics. Thus, it is necessary to assess the steady state and dynamic performance a for different installing scenarios plants such as photovoltaic (PV) ones. paper specifically investigates impacts very (VLS-PV) on including rotor-angle frequency stabilities. For this purpose, detailed equ...
