I Suoli su substrati acidi in Sardegna: nota 1.: indagine preliminare sui suoli del Massiccio del Monte Limbara

In this first note the Author describes geology, morphology, climate and vegetation of the Limbara massif and reports the first results of the pedological study. The soils differ according to the differentiated altimetric position and vegetative cover; above 1000 meters they are acid and present a strong accumulation of organic matter. These soils have been dassified as Umbrepts. Below 1000 meters the soils become less acid and the organic matter content decreases, they have been classified as Ochrepts and Orthents

I Suoli su substrati acidi in Sardegna: nota 3: alcune osservazioni sui suoli del versante sud-est del Massiccio del Limbara

The Authors describes principal soils of the SE-facing slopes of Limbara relief. Lithic Haplumbrepts are the principal soils above 1100 m, Lithic and Tipic Xerochrepts are widely distributed between 1100 and 700 m and Lithic Xerorthents are the principal soil from 700 to 450 m. In this work differences with the soil of NW-facing slopes are described. In the SE-facing slopes the transition to Xerochrepts isn't gradual, cambie horizon is uncommon and the soils between 800 and 500 m have an higher content of clay and higher saturation

Le Bentoniti della Sardegna settentrionale: nota: 1.

In this note the authors relate about some deposits of bentonite in the Northern Sardinia. This island is very interesting in order to bentonites that are among the most important in Europe. This work characterises each deposit describing it in geografical situation. Chemical, technological and X-ray analysis have been executed. Each deposit is described in its geology and valued in order to industrial use of bentonite. All bentonite deposits, that have been studied in this notet are very wide and very interesting in order to quality of bentonite

I Suoli su substrati acidi in Sardegna: nota 4.: i suoli del Massiccio dei Sette Fratelli

The Authors present the results of a pedological study on Sette Fratelli relief (Sud-East Sardlnia). Lithic Xerothents are the principal soils in upslope positons and steepness of the slope control their development. Lithic and Typic Xerochrepts are the typic soils of remaining area and vegetation help their development. High base content is one of the most interesting characteristic in these soils

Raffronto fra i Suoli rossi Calcarei e la «Terra Rossa» della Sardegna nord-occidentale: prime considerazioni

Tale studio ha lo scopo di investigare un'area campione di circa 10.000 Ha; tutto ciò per determinare in dettagli le caratteristiche territoriali, procedere alla loro valutazione, per poi concludere con un giudizio sulla potenzialità del territorio medesimo. Il fine riguarda la possibilità di differenziare, in prima approssimazione, due unità pedologiche molto diffuse nella Sardegna nord-occidentale ed in particolar modo nell'area in istudio: i suoli rossi calcarei e la «Terra Rossa »

I Suoli su substrati acidi in Sardegna: nota 2.: i suoli del versante nord-ovest del Massiccio del Limbara

Factors of soils formation of the NW-facing slopes of Limbara relief are described. The climatic factor is considered to be the most important factor in determining the properties of soils in upslope positions (1300-1100 m). The principal soils are Lithie Haplumbrepts. The morphology and vegetation help the development of the soils between 1100 and 800 m. They are Typic Xerumbrepts. Between 800 and 500 m the principal soils are Lithic Xerorthents. Steepness of the slope controls their development

Studio geo-idrologico della Sardegna settentrionale: memoria 6.: il bacino idrografico del Fiume Temo

This comment consists essentially of three well defined partes: the is first physical geography, the second hydrogeology and the last is hydrogeochemistry. The AA., after a preliminary and organic geological investigation which permitted the preparation of the map (Fig. 3) in which the various geolithologic units are corelated, then made a particular study of the principal geomorphologic structures present in the entire basin. The multiple presence of such structure is justified in the geological difference of the formations present. Among the typical structures of the basic vulcanites was the evidence of cushion lava, block lava and tabularcolumn lava; among the typical acid vulcanites are the stratoid lava and the cave like structures. Also the evidence were the pointed tabular structures, the concave tabular structures and the dip-shop, tabular structures present in the series of lava flows, and of porous stone deposits and sea deposits in alternate stratus. The part relative to the hydrogeology was preceded by an examination of the climatology and the hydrometry of the basinc. Five meteorological rain measuring stations and two thermometeorological rain measuring stations were used for this study and the following information were gathered: - the maximum precipitations were concentrated in the late autumn period, in winter and in the early spring; the maximum aridity was during the summer months; there is a great irregularity in the intensity of the precipitations; within the area of the basin proportional differences of values of precipitation due to altitudes do not exist. The hydrometric characteristics of the basin have been brought to light using the information of hydrometric data given by the station at Reinamare. From an hydrological point of view, by suddividing the general area into thre larges complexes based on their permeability, the most important hydrogeological series and water structures of the basin have been located. As well as this, 60 perpetual water springs have been registered, and for the most part they have been actually identified and their waters have been analized and studied. These analysis have proved the waters as belonging to three families: magnesium-chloride water, sodium-bicarbonate water and sodium-sulphate water. This latter water family which includes the majority of the springs, whose sources are diffused almost all over the enti re area of the basin, presents a fairly similar chemical characteristic as we have found by using linear co-relations with pairs of geochemical «parameters»

clinical evolution of cerebral coenurosis from invasive to chronic infection in sheep and a goat

This survey describes the evolution in vivo of Coenurus cerebralis in small ruminants. At presentation, neurological signs and cerebrospinal fluid (CSF) features were suggestive of multifocal or diffuse inflammatory reaction. Magnetic resonance imaging (MRI) captured the transition between the invasive and quiescent phase of the infection, revealing the concurrent presence of meningitis and small cysts. During the quiescent phase, in all animals, neurological symptoms disappeared, and cerebrospinal fluid was unremarkable while cysts grew progressively. Subsequently, the onset of neurological symptoms coincided with MRI signs of diffuse or localized increase of intracranial pressure, as confirmed by direct intracranial pressure measuring. All the animals had an excellent post-surgical recovery. This is the first report describing the evolution of coenurosis in vivo. Sequential imaging allowed describing interesting such as the death of some coenuri and different parasite growth rate in the same host

Differences in family caregiver experiences and expectations of end-of-life heart failure care across providers and settings: a systematic literature review

Abstract Heart failure impacts patients’ quality of life and life expectancy and significantly affects the daily behaviours and feelings of family caregivers. At the end-of-life, the burden for family caregivers depends on their emotional and sentimental involvement, as well as social costs. Objectives: The aim of this work is to determine whether and how family caregivers’ experiences and expectations vary in relation to the places of care and teams involved in heart failure management. Methods: A systematic literature review was conducted, by screening manuscripts dealing with the experience of Family Care Givers’ (FCGs) of patients with Advanced Heart failure. Methods and results were reported following the PRISMA rules. Papers were searched through three databases (PubMed, Scopus and Web of Science). Seven topics were used to synthetize results by reporting qualitative information and quantitative evidence about the experience of FCGs in places of care and with care teams. Results: Thirty-one papers, dealing with the experience of 814 FCGs, were selected for this systematic review. Most manuscripts came from the USA (N = 14) and European countries (N = 13) and were based on qualitative methods. The most common care setting and provider profile combination at the end of life was home care (N = 22) and multiprofessional teams (N = 27). Family caregivers experienced “psychological issues” (48.4%), impact of patients’ condition on their life (38,7%) and “worries for the future” (22.6%). Usually, when family caregivers were unprepared for the future, the care setting was the home, and there was a lack of palliative physicians on the team. Discussion: At the end-of-life, the major needs of chronic patients and their relatives are not health related. And, as we observed, non-health needs can be satisfied by improving some key components of the care management process that could be related to care team and setting of care. Our findings can support the design of new policies and strategies
