Un giorno alla volta, un'ora alla volta
No full textIl volume, nato un’idea di Daniele Di Benedetto e Marianna Bruno, e realizzato a cura dell’Associazione Sanfilippo Fighters Odv, racconta le storie meravigliose dei bambini e dei ragazzi affetti dalla Mucopolisaccaridosi di tipo III, meglio nota come Sinfrome di Sanfilippo, una malattia rara ereditaria con insorgenza pediatrica che causa una progressiva e inesorabile degenerazione neurologica con perdita delle capacità motorie e rapido deterioramento cognitivo (capacità di apprendimento e di comunicazione). Come si legge in quarta di copertina del volume, il libro racconta «Storie di parole acquisite e poi dimenticate. Storie di corse al parco che diventano passi lenti e incerti. Storie di bambini e adolescenti capaci di sorridere, anche solo con gli occhi. Storie di un futuro preso con forza e portato via. Storie di una vita vissuta un giorno alla volta, un’ora alla volta.»
Prefazione di Alessandro Fraldi. Con un testo di Gabriele Cirilli. L'immagine di copertina è di Federica Di Stefano. L’acquisto del libro sostiene le attività dell’Associazione Sanfilippo Fighters Odv
Diagnostic study of the Volta Basin fisheries: Part 1 overview of the fisheries resources
No full textThe Basin Focal Project for the Volta (BFP-Volta) is a research project funded by the Challenge Programme on Water and Food (CPWF). Its aim is to provide an in-depth analysis of the basin through three main thematic issues: water-poverty, water availability/use and water productivity. The overall objective of the BFP-Volta is to contribute to the main goal of the CPWF, that is, to alleviate poverty through better management of water in order to enhance agricultural productivity and environment conservation. In this context, the WorldFish Center has been commissioned to produce a series of two complementary reports focusing more specifically on the fisheries resources and the link that may exist between poverty and fisheries in the Volta basin. The present report is the first of these two documents. It should be seen as a preliminary analysis presenting a background of the fisheries resources in the Volta Basin essentially from a biological perspective. Its specific objective is to conduct a diagnostic analysis of the status of the Volta basinÆs inland fisheries, with a particular focus on the biological productivity of the various water bodies existing in the basin. Whenever possible, the diagnostic will be proposed in relation to the current exploitation rate of the fisheries resources. The analysis will include the Volta Lake, but also the other hydropower reservoirs, rivers, floodplains, and the numerous small-scale seasonal or permanent ponds that are scattered throughout the basin. Particular attention will be paid, however, to Lake Volta, reflecting the large number of fishery-dependent communities that live on its shores. The report will also concentrate on two countries within the basin: Ghana and Burkina Faso as together they cover more than 83% of the total basin surface.Fishery resources, Inland fisheries, Dams, Ghana, Voltaian Basin, Ghana, Volta L., Africa,
A study of the transmission of Schistosoma haematobium in Volta Lake, Ghana
No full textA field study on the ecology
and epidemiology
of
S. haematobium
was carried out in 8 different parts of the
Volta Lake from
November
1978 to June 1980. Snail sampling
for
B.
rohlfsi was
conducted
monthly in 39 lakeside villages and
data
on
human
prevalence
rates
and egg counts were obtained
in
30
of
the
villages.
A
detailed,
integrated study of S. haematobium was
conducted
at the large lake-
side village of Agbenoxoe.
The snail sampling technique was an efficient version of the
man-
time method. For screening urine
samples
for
S.
haematobium
eggs, the
"Nuclepore" filtration method
was
used
-
its first large-scale, field
application. At Agbenoxoe, a
new method of recording
water
contact
data was initiated.
From snail sampling,
it
was
learned that
S.
haematobium trans-
mission was distinctly seasonal, and
intensity
varied according to the
type and amount of vegetation
in
water contact
points
(WCPs), the
shape of the WCPs, and their geographical
location.
S.
haematobium
infection rates in B. rohlfsi around the lake
were
among the
highest
in the world. The snail had a
high intrinsic
rate of
natural
increase,
but could not maintain an equilibrium
population
in the
unstable
habi-
tat of the lake. An original mathematical model was
developed to
describe the dynamics of S.
haematobium transmission to
B.
rohlfsi.
S. haematobium prevalence rates and egg counts
were
exceptionally
high in 2 lake sections -
the
Afram
and
Obosum branches
-
mainly
because of past and present growth
of
Ceratophyllum
which
led to
high
transmission during most months of the
year.
However transmission
became interrupted when Ceratophyllum density
became too
great and
decayed in WCPs. Levels of
infection
were
lower in
the
other
lake
sections surveyed, mainly
because
of
less
Ceratophyllum
growth which
confined high transmission to
December to
March
each
year.
Analysis
of all the human data revealed that the
5-
19
year-old
age
span
was
responsible for 93% of the potential
contamination
of
S. haematobium
eggs in the Volta Lake.
At Agbenoxoe, snail sampling,
prevalence,
egg
count,
incidence,
and
water contact data fit together to
paint
a
uniform
picture
of very
focal
and seasonal transmission

Il canzoniere di Ludovico Ariosto nel ms. Rossiano 639. Edizione e commento
No full textLa tesi offre un'edizione commentata delle rime di Ludovico Ariosto contenute nel manoscritto Rossiano 639 della Biblioteca Apostolica Vaticana. Il codice, rinvenuto nel 1985, è l'unico testimone di un possibile canzoniere ordinato dall'autore. A una contestualizzazione della raccolta nel panorama della rimeria di primo Cinquecento, segue una presentazione del manoscritto e dei suoi rapporti con la tradizione testuale delle rime ariostesche. Si offre quindi l'edizione dei testi, per la prima volta corredati da un commento scientifico che mette in luce le fonti, i modelli, i legami con il resto della produzione ariostesca e gli aspetti metrico-stilistici di rilievo
On two Möbius functions for a finite non-solvable group
No full textLet G be a finite group, μ be the Möbius function on the subgroup lattice of G, and λ be the Möbius function on the poset of conjugacy classes of subgroups of G. It was proved by Pahlings that, whenever G is solvable, the property (Formula presented.) holds for any subgroup H of G. It is known that this property does not hold in general, the Mathieu group M 12 being a counterexample. In this paper we investigate the relation between μ and λ for some classes of non-solvable groups, among them, the minimal non-solvable groups. We also provide several examples of groups not satisfying the property
