Compost Amendment Impact on Soil Physical Quality Estimated from Hysteretic Water Retention Curve
2022
Capacity-based indicators of soil physical quality (SPQ) and pore distribution parameters were proposed to assess the effects of compost amendment but their determination was limited to desorption water retention experiments. This study also considered the pore size distribution obtained from adsorption experiments to establish the effectiveness of compost amendment in modifying the physical and hydrological attributes of a sandy loam soil. Repacked soil samples with different compost to soil ratios, r, were subjected to a wetting–drying cycle, and the water retention data were fit to the van Genuchten model to obtain the pore volume distribution functions. The soil bulk density was m…

Entry and processing of Borrelia burgdorferi pleomorphic forms
2015
Lymen borrelioosi on Suomessakin yleinen puutiaisten levittämä tauti. Borrelioosin ensimmäisiä oireita ovat muun muassa puutiaisen pureman ympärille muodostuva ihottuma, päänsärky, väsymys ja kuume. Myöhemmin tauti voi aiheuttaa nivel- tai sydäntulehduksen sekä neurologisia oireita. Borrelioosi on monessa suhteessa kiistanalainen tauti, sillä esimerkiksi sen hoidosta ja mahdollisesta kroonistumisesta on kaksi eriävää näkemystä. Taudin aiheuttaja on Borrelia burgdorferi -bakteeri (Bb). Bb pystyy välttelemään isännän immuunipuolustusta useilla eri mekanismeilla. Bakteeri on korkkiruuvinmuotoinen spirokeetta, mutta voi esiintyä myös epätyypillisinä muotoina, joihin kuuluu esimerkiksi pyöreä mu…
Aislamiento y función de células progenitoras endoteliales de sangre periférica durante la evolución clínica de pacientes con infarto agudo de miocar…
2015
Las células endoteliales (CE) recubren el interior de los vasos sanguíneos constituyendo el endotelio, actualmente considerado un órgano muy activo e implicado en la regulación del tono vascular, el tráfico de células sanguíneas, el equilibrio hemostático, la permeabilidad, la proliferación, la supervivencia, y la respuesta inmunitaria tanto adaptativa como innata. Los factores de riesgo cardiovascular como la hipercolesterolemia, la diabetes y el tabaquismo pueden causar lesiones endoteliales, uno de los principales desencadenantes de la patogénesis en la aterosclerosis, predisponiendo al desarrollo y progresión de enfermedades cardiovasculares. Hoy en día, las enfermedades cardiovasculare…
miMic
2016
miMic, a sonic analogue of paper and pencil is proposed: An augmented microphone for vocal and gestural sonic sketching. Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control. The physical device is based on a modified microphone, with embedded inertial sensors and buttons. Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control. With miMic, the sound designer can explore a vast sonic space and quickly produce expressive sonic sketches, which may be turned into sound prototypes by further adjustment of model…
The Influence of Sewage Sludge and Fly Ash Fertilization on the Total Number of Bacteria (TNB) and Bradyrhizobium Species in Soybean Agroecosystem
2023
The aim of this study was to determine the impact of different chemical properties in soil, including changes in magnetic susceptibility and the impact of humic substances from sewage sludge and fly ash on the microbial community in the soybean agroecosystem. A field experiment was carried out using the random plot method on Cambisol with a texture of silt loam. The experiment consisted of 24 plots (six treatments and four replications) using different dozes of sewage sludge and fly ash. The following physicochemical and chemical analyses were performed in the soil samples: pH in KCl, conductivity (λ), total content of heavy metal, magnetic measurements and fractional composition of …
Optical Monitoring of Microplastics Filtrated from Wastewater Sludge and Suspended in Ethanol.
2021
The abundance of microplastics (MPs) in the atmosphere, on land, and especially in water bodies is well acknowledged. In this study, we establish an optical method based on three different techniques, namely, specular reflection to probe the medium, transmission spectroscopy measurements for the detection and identification, and a speckle pattern for monitoring the sedimentation of MPs filtrated from wastewater sludge and suspended in ethanol. We used first Raman measurements to estimate the presence and types of different MPs in wastewater sludge samples. We also used microscopy to identify the shapes of the main MPs. This allowed us to create a teaching set of samples to be characterized …
Acaricidal Activity of Bufadienolides Isolated from Drimia pancration against Tetranychus urticae, and Structural Elucidation of Arenobufagin-3-O-α-L…
2022
Chemical characterization of the bulbs of Drimia pancration was conducted to isolate four steroidal saponins (1–4). Earlier, we focused on the structural elucidation of compounds 1–3. Herein, by means of 1H-NMR, 13C-NMR, Nuclear Overhauser Effects (NOE), and 2D-NMR spectra, the full stereochemical structure of 4 is reported, and all the 1H and 13C signals are assigned. Compounds 1–4 were tested for their acaricidal properties against the two-spotted spider mite Tetranychus urticae. Our results showed excellent activity of compound 1, with an LD50 (µg/cm2) of 0.29 and a LD90 (µg/cm2) of 0.96, whereas compounds 2, 3, and 4 showed moderate activity. Furthermore, t…
Sicilia, 1 : l'acropoli di Gela : stipi, depositi o scarichi
2005
The subject of the book is the study of the votive stipes or deposits found on the acropolis of Gela during the excavations conducted in the 1960s. The materials are examined and an interpretative hypothesis is advanced on the chronology and on the divinity to whom the offering is addressed.
