No full textIntroduction of General Distributions on Sphere and Torus in View of Time Series Spectra
No full textThere are various fields where observations are taken on directions in three dimensions, e.g., sphere and torus. Herewe will introduce a very general family of distributions on sphere and torus by use of time series spectra, which includes a lot of proposed classical one as special cases. Because time series spectra can be described by a lot of famous parametric models, e.g., AR, ARMA etc., we can develop the systematic model selection in this field by use of AIC, BIC, etc. Applications are very wide
Superfici intrinseche regolari nei gruppi di Carnot
No full textA Carnot group is a simply connected, nilpotent Lie group with stratified Lie algebra. Intrinsic regular surfaces in Carnot groups play the same role as C1 surfaces in Euclidean spaces. As in Euclidean spaces, intrinsic regular surfaces can be locally defined in different ways: e.g. as non critical level sets or as continuously intrinsic differentiable graphs. The equivalence of these natural definitions is the problem that we are studying. This is a note based on the paper [8].Un gruppo di Carnot è un gruppo di Lie nilpotente e semplicemente connesso che ammette una Lie algebra stratificata. Nei gruppi di Carnot, le superfici intrinseche regolari giocano lo stesso ruolo delle superfici C1 negli spazi euclidei. Come negli spazi euclidei, esse posso essere viste in diversi modi: per esempio, come insiemi di livello non critici oppure come grafici di mappe intrinsecamente differenziabili. L'equivalenza tra queste definizioni è il problema che viene preso in esame. Questo lavoro è basato sull'articolo [8]
Antropocene, storia e politica. Sfide e itinerari critici
No full textThe essay addresses some questions that the concept of the Anthropocene poses not only to political theory but also to the humanities and social sciences. Along a critical itinerary among different theories and authors (from Chakrabarty to Latour, from Moore and Malm to ecofeminism), the essay discusses the concept of the Anthropocene with a ‘political ecology’ approach. The aim is to hold together the common dimension - human and non-human - of belonging to terrestrial eco-systems, with the ability to critically and genealogically read the power asymmetries, inequalities and conflicts that have made possible and still structure the Anthropocene, from the political perspective of inter-human and multi-species climate justice.Il saggio affronta alcune questioni che il concetto di Antropocene pone non solo alla teoria politica ma anche alle scienze umane e sociali. Lungo un percorso critico fra teorie e autori diversi (da Chakrabarty a Latour, da Moore e Malm fino all'ecofemminismo), il saggio discute il concetto di Antropocene con un approccio di “ecologia politica”. L'obiettivo è di tenere insieme la dimensione comune - umana e non umana - dell’appartenenza agli eco-sistemi terrestri, con la capacità di leggere criticamente e genealogicamente le asimmetrie di potere, le disuguaglianze e i conflitti che hanno reso possibile e che tuttora strutturano l’Antropocene, nell’ottica politica di una giustizia climatica interumana e multi-specie
The biodegradation of low-density polyethylene by Bacillus species
No full textPolyethylene (PE) products have short-term applications, resulting in the daily release of enormous quantities of plastic wastes into the environment with their attendant public and environmental health threats of global concern. Developing an eco-friendly management method to abate the menace prompted this research work. Four Bacillus species were isolated from different dumpsites in Owerri Metropolis, and identified using 16S rDNA sequencing, as B.pumilus, B.siamensis, B.coagulans and B. subtilis. The ability of the microbial isolates to degrade polyethylene (table water sachets) was determined using microbial growth measurement in liquid medium (Optical Density (OD600)), disappearance and introduction of functional groups (Fourier Transform Infrared spectroscopy (FTIR) and weight loss analysis measured after sixty (60) days of incubation in mineral salt vitamin media. Microbial density showed a gradual and progressive increase from 0 day to 60 days : B. siamensis (0.12 - 0.84), B.pumilus (0.11-.67), B.coagulans (0.12 - 0.61) and B.subtilis (0.11 – 0.60), as against the control medium which remained unchanged (0.11). Similarly, FTIR spectra showed additional functional groups (carboxylic acids, ethers, esters, amines, methylene, alcohols, and alkenes in the polyethylene materials exposed to the test isolates: B.siamensis (17 peaks), B.pumilus (12 peaks), B.coagulans and B.subtilis (13 peaks each), but control (8 peaks). There were subatantial reduction in the residual weights of the PE materials: B.siamensis (52%), B.pumilus (26%), B.coagulans and B.subtilis (18% each). The observations showed that these Bacillus spp. indigenous to Owerri Metropolis have the ability to degrade PE and utilize it as a carbon source, and it was concluded that biodegradation was achieved, and that PE which was regarded to be inert can be biodegraded when exposed to the right microorganisms

Spatial analysis of subsurface water quality: A case study from an arid region of India
No full textThis study assesses the physicochemical and heavy metal contamination of subsurface water in Bikaner City, Rajasthan. Samples were collected from various tube wells and analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), major cations (Na⁺, K⁺, Ca²⁺, Mg²⁺), anions (HCO₃⁻, Cl⁻, SO₄²⁻, F⁻, NO₃⁻), and heavy metals (Mn, Cu, Zn, Pb, Cr, U, As). The spatial distribution of these parameters was visualized using Inverse Distance Weighting (IDW) in QGIS. The results revealed that several regions exhibit high TDS and nitrate levels. Fluoride concentrations in some areas surpassed the permissible limit (1.5 mg/L), raising concerns about potential health risks associated with dental and skeletal fluorosis. Heavy metals such as uranium and manganese were detected at varying concentrations, with localized hotspots exceeding permissible limits. The findings emphasize the importance of addressing both natural and anthropogenic sources of contamination to safeguard public health and promote sustainable water use in the arid region
