Georeferenced vascular plant collections in south Tuscany (Italy)
No full textThe dataset refers to 4535 selected floristic collections mainly done by the first author in southern Tuscany (Maremma, Italy) during the last 35 years (1989-2024, Herbarium F. Selvi). The collections are largely unpublished and currently kept in the Herbarium Centrale Italicum at the Natural History Museum of Florence University (FI, H.C.I.). The collections belong to 1766 specific and subspecific taxa with updated names according to the Portal to the Flora of Italy, in 122 families of vascular plants. Each record is associated with textual information on the collection locality, date, collector(s), number and geographical coordinates in the WGS84 system. Many collections were made in floristically poorly known parts of the region and mostly in the province of Grosseto, documenting new sites of several uncommon or phytogeographically relevant taxa. The information dataset allows to deepen the botanical knowedge of Tuscany and central Italy
Garrigue plant communities of ultramafic outcrops of Tuscany (central Italy)
No full textGarrigue plant communities of the ultramafic outcrops in Tuscany are here analyzed from a phytosociological point of view on the basis of original and published data. All the investigated vegetation types belong to the association Armerio-Alyssetum bertolonii, already described from Monte Ferrato. Two subassociations, typicum and Euphorbietosum spinosae subass. nova, are recognized, their distribution evidenced and their structural and chorological differences pointed out. The syntaxonomical problems of the Tuscan ultramafic communities are discussed. -Author
Thirty-five years of floristic collections in southern Tuscany (Italy)
No full textFloristic knowledge and georeferenced information about vascular plant species distribution in southern Tuscany (Italy) are still poor for supporting effective biodiversity conservation efforts.A dataset of georeferenced floristic collections from Southern Tuscany, which was developed by the first author between 1989 and 2024, is provided and briefly commented on. The dataset includes data for 4535 herbarium specimens, mostly unpublished, currently preserved in the Herbarium Centrale Italicum at the Natural History Museum of Florence (FI). The specimens belong to 1766 species and subspecies in 122 families of vascular plants. Each record is associated with a Unique Identifier (UID) and information on the collection locality, date, collector(s), and geographical coordinates (WGS84 geodetic datum). Many specimens were collected in areas that were poorly investigated, documenting new sites for several uncommon or phytogeographically relevant taxa. The dataset includes two specimens of Euphorbia meuselii Geltman, a forest herb endemic to Southern Italy and new to the flora of Tuscany. Overall, this dataset allows a relevant advancement in the floristic knowledge of central Italy

Determination of aluminum in dialysis concentrates by atomic absorption spectrometry after coprecipitation with lanthanum phosphate
Full text linkk, selvi/0000-0002-9912-8586This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosphate. the analytical parameters that influenced the quantitative coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. the % recoveries of the analyte ion were in the range of 95-105 % with limit of detection (3s) of 0.5 mu g I-1. Preconcentration factor was found as 1000 and Relative Standard Deviation (RSD) % value obtained from model solutions was 2.5% for 0.02 mg L-1. the accuracy of the method was evaluated with standard reference material (CWW-TMD Waste Water). the method was also applied to most concentrated acidic and basic dialysis concentrates with satisfactory results.Unit of the Scientific Research Project of Erciyes Univercity [EUBAP FBY-10- 3077]The author is grateful for the financial support of the Unit of the Scientific Research Project of Erciyes Univercity (Project no: EUBAP FBY-10- 3077)
Conceptual Process Design and Techno-Economical Assessment of H2/CO2 Separation Using FricDiff Technology
No full textThe technology of FricDiff, an abbreviation of Frictional Diffusion, can be used to separate gases by adding a third gas, a so-called sweep gas, to the system. It is based on the diffusion difference of the feed molecules in the sweep gas. FricDiff is a proven principle and works at lab scale. The aim of the research is to study the technical and economical feasibility of separating H2 and CO2 with a FricDiff separation process at large scale. It includes the design of H2/CO2 separation unit for a medium size power plant using IGCC technology and a feasibility study. The results are compared with other separation methods that are used to capture and separation CO2 from H2IRSProcess and EnergyMechanical, Maritime and Materials Engineerin
Fricdiff: Parameter estimation and feasibility assessment of combination of Fricdiff and reaction
No full textFricdiff, which either stands for frictional diffusion or frictional difference is a separation technology for the separation of gas and vapour mixtures. It is based on the difference of diffusional velocities of the components to be separated in an additional component, called sweep gas, through a porous barrier. This work has two objectives. The first objective is to estimate the average pore diameter and porosity-tortuosity factor, two parameters important for the transport through the porous barrier. The second objective of this thesis is a feasibility assessment of the combination of Fricdiff with an equilibrium limited chemical reaction. The reaction used to assess this feasibility is the water-gas shift reactionIRSProcess and EnergyMechanical, Maritime and Materials Engineerin
Effect of leaf extract of Pongamia glabra (Vent.) (Fabaceae) on histological changes of fat body of Periplaneta americana (Linn.) adult male
No full textThe fat body of Periplaneta americana usually contains trophocytes, urocytes and mycetocytes. The fat body showed some marked changes in insects injected with a sublethal concentration of Pongamia glabra [P. pinnata] leaf extract (0.05 ml of 5% concentration) through the intra-peritoneal membrane. In treated insects, the lipid vacuoles of the trophocytes disintegrated, and swollen and irregular shaped nuclei were conspicuous. The mycetocytes decreased in size, and the urocytes mostly disintegrated..RE: 16 ref.; SC: ZA; HE; VE; CA; TR; PA; 0JSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0378-9519&isbn=&volume=21&issue=4&spage=355&pages=355-359&date=1997&title=Journal%20of%20Entomological%20Research&atitle=Effect%20of%20leaf%20extract%20of%20Pongamia%20glabra%20%28Vent.%29%20%28Fabaceae%29%20on%20histological%20changes%20of%20fat%20body%20of%20Periplaneta%20americana%20%28Linn.%29%20adult%20male.&aulast=Ramanathan&pid=%3Cauthor%3ERamanathan%2c%20B%3bRajasekarapandian%2c%20M%3bSelvi%20Sabhanayakam%3C%2Fauthor%3E%3CAN%3E19980505846%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3
An Indigenous epistemological approach to promote health through effective knowledge translation
Full text linkThrough indigenous epistemologies a holistic health framework is promoted and indigenous
concepts like two-eyed seeing offer critical decolonizing conduits for knowledge translation and
enhanced health outcomes. Yet, in health care settings dominance of scientific research-based
evidence downplays tacit knowledge. For enhanced health outcomes in indigenous community
settings, effective knowledge translation is essential through synthesis of research-based explicit
knowledge and tacit know-how adapted to local needs. This paper discusses essential
characteristics of effective knowledge translation practices, and presents two examples of best
practices of knowledge translation in indigenous contexts
Manajemen Pelayanan Pajak Di KPP Pratama Jakarta Matraman
Full text linkThe purpose of this study is to analyze the management of tax services at KPP Pratama Jakarta Matraman, the obstacles that arise in the management of tax services at the Primary Tax Office of Matra-man, Jakarta, and the efforts made by the Primary Tax Office of Matraman, Jakarta in overcoming these obstacles. In this study, the author analyzed the data using a qualitative descriptive method based on a case study, where the author conducted in-depth inter-views with informants and collected as much data as possible for re-view. The results of this study indicate that the management of tax services carried out by the Primary Tax Office of Matraman, Jakarta is good in terms of organization but not optimal in terms of planning due to new policy constraints that require taxpayers to reduce inter-actions with tax office employees due to the Covid-19 pandemic. The author suggests that the Primary Tax Office of Matraman, Jakarta pay attention to the performance of its employees, especially in tax services to the community, one of which is by controlling every achievement of the performance of its employees who work in the office or from home in order to realize optimal service to the commu-nity
