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 The collections are largely unpublished and currently kept in the Herbarium Centrale Italicum at the Natural History Museum of Florence University (FI, H.C.I.).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

ANALISIS KAPASITAS SUMBER DAYA MANUSIA DEWAN PERWAKILAN RAKYAT DAERAH KABUPATEN GARUT DALAM PENYELENGGARAAN FUNGSI LEGISLASI PERIODE 2014-2019
Get PDFPenelitian ini dilatarbelakangi dari akumulasi permasalahan yang berakar dari lemahnya kapasitas Dewan Perwakilan Rakyat (DPRD) Kabupaten Garut Periode 2014-2019. Lemahnya kapasitas lembaga legislatif tersebut terlihat dari tidak terakomodirnya aspirasi, keinginan, dan tuntutan masyarakat Kabupaten Garut yang terlihat dari minimnya usulan Ranerda setiap tahunnya yang hanya satu produk usulan. Dampak yang ditimbulkan kemudian yaitu banyaknya pekerjaan rumah berupa proyek yang tidak kunjung terselesaikan seperti proyek Pasar Leles, Art Center, dan Sarana Olahraga Ciateul yang mangkrak dan otomatis menimbulkan kerugian negara. Ihwal tersebut diperparah dengan kedisiplinan anggota DPRD dalam menyelenggarakan kewajibannya. Tujuan penulisan ini adalah menganalisis kapasitas sumber daya manusia DPRD Kabupaten Garut dalam Penyelenggaraan Fungsi Legislasi Periode 2014-2019, penelitian ini menggunakan basis analisis capacity building dari Grindle (1997:1-28) yang berfokus terhadap aspek pengembangan sumber daya manusia (SDM). Hasil penelitian menunjukan bahwa penyelenggaraan pemerintahan daerah berdasarkan tugas pokok dan fungsi oleh DPRD Kabupaten Garut dalam penyelenggaraan fungsi legislasi periode 2014-2019 berdasarkan aspek sumber daya manusia dikatakan masih lemah. Hal tersebut terbukti dari minimnya usulan Ranerda oleh DPRD Kabupaten Garut yang cenderung tidak sebanding dengan usulan Ranerda eksekutif, lemahnya penyelenggaraan dalam mengkomodir tuntutan dan keinginan masyarakat terlihat dari penolakan audiensi masyarakat oleh DPRD, di samping banyaknya perilaku tidak disiplin seperti ketidakhadiran dalam Rapat Paripurna dan bermain games saat rapat berlangsun
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
Get PDFk, 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)
GOVERNMENT PUBLIC RELATIONS STRATEGY IN ENHANCING THE INSTITUTIONAL IMAGE OF THE HOUSE OF REPRESENTATIVES OF THE REPUBLIC OF INDONESIA
Get PDFThe institutional image of the House of Representatives of the Republic of Indonesia (DPR RI) is a crucial element of government administration, as it directly influences political legitimacy, the effectiveness of representative functions, and the quality of state–society relations. This study aims to examine the government public relations strategy of the DPR RI as an integral component of public communication governance in strengthening the image of the legislative institution. Using a descriptive qualitative approach, the research draws on field observations, in-depth interviews, document analysis, and literature review to explore how DPR RI Public Relations performs its strategic role in accordance with principles of public administration and government public relations standards. The findings indicate that the DPR RI’s communication strategy operates through four main instruments: digital communication, public information disclosure services through the Information and Documentation Management Officer (PPID), public education programs, and media relations. These instruments are implemented using the RACE (Research, Action, Communication, Evaluation) model as an operational framework for planning, executing, and evaluating public communication. Furthermore, the strategy reflects the Dynamic Government paradigm, particularly in terms of thinking ahead, thinking across, thinking again, and digital adaptation, emphasizing institutional adaptability, cross-unit coordination, and organizational learning. However, the study also identifies persistent challenges, including limited human resources, underdeveloped communication standard operating procedures, and high exposure to negative media coverage. Therefore, strengthening governance-based public relations strategies, enhancing communication capacity, and modernizing the digital ecosystem are essential to building a more credible, accountable, and sustainable institutional image of the DPR RI
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.

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
