A significant amount of distributed photovoltaic (PV) generation is "invisible" to distribution system operators since it behind the meter on customer premises and not directly monitored by utility. The essentially adds an unknown varying negative demand system, which causes additional uncertainty in determining total load. This impacts reliability, cold load pickup, behavior modeling, hence cost operation. Thus, essential create low-complexity localized models for estimating power from...

<h3>ABSTRACT</h3> <h3>Background</h3> Fibromyalgia and myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) are poorly understood conditions with overlapping symptoms, fuelling debate as to whether they manifestations of the same spectrum or separate entities. Both associated hypermobility, but this remains significantly undiagnosed, despite impact on quality life. <h3>Objective</h3> We planned understand relevance hypermobility symptoms in fibromyalgia ME/CFS. <h3>Method</h3>...

Pyritized twigs and roots from the Eocene London Clay of SE England were studied to gain a better understanding process pyritization by investigating pyrite textures in relation cell type quality preservation. Highly polished sections fractured surfaces taken 124 specimens examined using optical microscope SEM, latter equipped map carbon. Pyrite include microcrystalline, framboidal, massive polycrystalline, subhedral or euhedral forms. The highest fidelity preservation is always associated...

Abstract A third of patients receiving Interferon-α (IFN-α) treatment for Hepatitis-C develop major depressive disorder (MDD). Conversely, anti-Tumor Necrosis Factor (TNF) therapies improve depression providing key empirical support the “inflammatory theory” depression. Heightened amygdala reactivity (particularly to negatively valanced stimuli) is a consistent finding within MDD; can predict efficacy and reverses following successful treatment. However, whether IFN-α anti-TNF...

In remote areas, extending a power line to the primary electricity grid can be very expensive and losses are high, making connections almost impossible. A well-designed microgrid that integrates renewable energy resources help areas reduce investment costs while providing reliable source. Therefore, investigating design of an independent economically practical system for these is necessary plays important role. This paper introduces procedure isolated using HOMER software (HOMERPro 3.14.5)...

This study sought to explore whether generalised joint hypermobility (GJH, a common marker of variant connective tissue) was risk factor for self-reported non-recovery from COVID-19 infection. Prospective observational study. COVID Symptom Study Biobank (https://cssbiobank.com/) UK. Participants were surveyed in August 2022. 3064 (81.4%) reported at least one infection with COVID-19. These individuals on recovery and completed self-report questionnaire detect GJH (Hakim Grahame 5-part...

The labellar papillae and trichomes of Maxillaria Ruiz & Pav. show great diversity. Although also occur upon other parts the flower (e.g. column anther cap), these have not yet been studied. Labellar are useful in taxonomy, but hitherto taxonomic value floral has assessed. aim this paper is to describe range found determine whether as characters.Light microscopy, histochemistry, low-vacuum scanning transmission electron microscopy.A total 75 taxa were Conical with rounded or pointed tips...

Solid oxide fuel cell (SOFC)/ gas turbine (GT) hybrid systems possess the capability to nearly double efficiency of standard coal-fired power plants which are currently being used for large scale production. For purposes investigating and developing this technology, a SOFC/GT test facility was developed at U.S. DOE National Energy Technology Laboratory (NETL) in Morgantown, WV as part Hybrid Performance (HyPer) project. The HyPer utilizes hardware-in-the-loop technology simulate coupled SOFC...

The labella of Maxillaria acuminata Lindl., M. cerifera Barb. Rodr. and notylioglossa Rchb.f., all members the alliance, produce a viscid wax-like secretion. Histochemical analysis revealed that chemical composition secretion is similar in three species, consisting largely lipid protein. Light microscopy low-vacuum scanning electron were used to investigate secretory process. In fourth taxon, cf. notylioglossa, transmission showed bodies are associated with smooth endoplasmic reticulum or...

Many orchid flowers have glands called elaiophores and these reward pollinating insects with oil. In contrast to other reward-producing structures such as nectaries, the anatomy of elaiophore process oil secretion not been extensively studied. this paper, structure is described for two members Oncidiinae, Oncidium trulliferum Lindl. Ornithophora radicans (Rchb.f.) Garay & Pabst. Elaiophores both species were examined using light microscopy, scanning electron microscopy transmission...

The elaiophores of Trichocentrum cavendishianum (Bateman) M.W. Chase & N.H. Williams, Oncidium loefgrenii Cogn., and Gomesa recurva R. Br. display considerable morphological anatomical diversity. Oil secretion by flowers T. O. can be related to the presence saddle-like, labellar callus, respectively, whereas, in G. recurva, although oil is present, no obvious structure appears involved its secretion. In first two species, secretory tissue consists palisade-like cells, these cells are oval....

Floral elaiophores, although widespread amongst orchids, have not previously been described for Maxillariinae sensu lato. Here, two claims that epithelial, floral elaiophores occur in the genus Rudolfiella Hoehne (Bifrenaria clade) are investigated. Presumed were compared with those of Oncidiinae Benth. and floral, resin-secreting tissues Rhetinantha M.A. Blanco Heterotaxis Lindl., both genera formerly assigned to Maxillaria Ruiz & Pav. (Maxillariinae stricto). Putative, elaiophore tissue...

Flowers of most species formerly included in Maxillaria are rewardless. Some, however, reward pollinators with nectar or pseudopollen, whereas the labella a relatively small number taxa produce lipoidal floral rewards that include resins and waxes. To date, labellar secretory tissues few have been examined detail, some rewardless having glossy thought to mimic rewards. Here, anatomy range resin-secreting, wax-secreting putative resin-mimic is compared using light microscopy, fluorescence...

Labellar food‐hairs in Polystachya Hook. exhibit considerable morphological diversity. The commonest type of trichome is uniseriate, two to four‐celled, with a clavate or subclavate terminal cell. This occurs amongst representatives most sections examined. Other trichomes are bristle‐like tapering fusiform cells, whereas section have moniliform that fragment the formation rounded elliptical component cells. Most contain protein and, while some starch, lipid invariably absent. presence...

As part of a study to explore diversity and disparity in Early Devonian terrestrial vegetation, several hundreds sporangia with situ spores have been isolated from Lochkovian locality Shropshire. These include small number (seven) showing dehiscence into four valves containing permanent sculptured dyads, belonging the Cymbohilates horridus complex C. cymosus, which are recorded coeval dispersed spore assemblages. A further, previously described, mesofossil comprises an incomplete sporangium...

Floral secretions are common in Bulbophyllum Thouars, and the labella of a number Asian species said to produce rich lipids that act as food rewards for insect pollinators. Although some these reports based on simple histochemical tests, much greater anecdotal and, hitherto, neither ultrastructure labellum nor secretory process has been investigated detail. Furthermore, sophisticated approaches have generally not applied. Here, both labellar structure four sect. Racemosae Benth. & Hook. f.,...

Smart meters and the advanced metering infrastructure facilitate distribution system operators (DSOs) to gather information on energy consumption at customer level. With increasing penetration of building-level intermittent distributed resources (DERs) behind meter, DER is not available DSOs. At same time, smart meter enables users participate in grid, with real-time information. Information for needed by user coordinate assets maximum benefits. The concept unbundled (USM) needs agents...

Conventional power grids dominated by synchronous generators gradually shift to variable renewable-energy-integrated grids. With the growth of building-level photovoltaic (PV) panels and other inverter-based resource (IBR) deployments in recent years, market retailers distribution operators have had deal with additional operational management challenges posed unobserved energy flow if its behind-the-meter (BTM) configuration. Also, intermittent stochastic nature IBR-based solar introduces...
