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 The collections are largely unpublished and currently kept in the Herbarium Centrale Italicum at the Natural History Museum of Florence University (FI, H.C.I.).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 The dataset includes data for 4535 herbarium specimens, mostly unpublished, currently preserved in the Herbarium Centrale Italicum at the Natural History Museum of Florence (FI).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
Assessment of Faunal Diversity in the College Campus of S. T. Hindu College, Nagercoil, Tamil Nadu, India
No full textIntroduction: Biodiversity assessment in semi-urban educational campuses is essential for understanding local ecological health, species richness, and the conservation value of managed green spaces.
Objectives: The present study aimed to document the faunal diversity of a College Campus in Tamil Nadu using the Visual Encounter Survey (VES) method from September 2024 to December 2024.
Results: A total of 62 species belonging to three phyla—Arthropoda, Mollusca, and Chordata—across six classes and multiple orders were recorded, with Arthropoda being the most dominant phylum (58 species). Insecta exhibited the highest species richness (54 species), followed by Arachnida (3 species), Gastropoda (1 species), Aves (2 species), and Reptilia (2 species). These findings underscore the ecological significance of semi-urban green spaces and highlight the need for conservation strategies such as habitat enrichment, pollution control, and biodiversity awareness initiatives.
Conclusion: The study provides baseline data that can support long-term ecological monitoring and conservation planning

Determination of aluminum in dialysis concentrates by atomic absorption spectrometry after coprecipitation with lanthanum phosphate
No full textk, 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
