The establishment of an organic farmers’ market as a training case study for Students of the Faculty of Agriculture in the University of Palermo

2010

The role of organic agriculture in the island of Sicily is well recognised by farmers, though the consumption of organic products still fails to largely develop in the local markets, due to several reasons, among which the small scale agricultural system and its structural poor organization plays a major role. The University of Palermo holds two major undergraduate and graduate courses on “Organic Agriculture” with a very good participation of Students. A student’s association was established with the aim of: a) encourage the consumption of organic products coming from local small scale farmers, and b) endorse the capacity of creating new job skillnes and opportunities for graduate students…

Podział wierzycieli na kategorie interesów w układzie częściowym

2018

Niniejsze opracowanie odnosi się do istotnego pod względem praktycznym i teoretycznym problemu dopuszczalności podziału wierzycieli na kategorie interesów w tzw. układzie częściowym. Układ częściowy nie jest osobnym rodzajem postępowania restrukturyzacyjnego: jest konstrukcją prawną możliwą do stosowania wyłącznie w postępowaniu o zatwierdzenie układu i w przyspieszonym postępowaniu układowym (art. 182 ust. 1 ustawy z 15.05.2015 r. - Prawo restrukturyzacyjne). Układ częściowy pozwala na restrukturyzację tylko części wierzytelności układowych, a także pozwala na „przymusowe” objęcie nim wierzytelności zabezpieczonych rzeczowo, z tym zastrzeżeniem że nie może w wyniku tego dojść do uszczerbku…

$MC$-hypercentral groups

2007

This paper is devoted to the imposition of some chain conditions on groups having a generalized central series. It is also given a characterization of MC-groups with finite abelian section rank: such class of groups is a suitable enlargement of the class of FC-groups. Mathematics Subject Classification: 20F24; 20F14

Investigations on the geographical variability of the human transferrins.

1971

On the basis of own and from the widely scattered literature compiled materials the geographical distribution of the transferrin alleles is discussed. They reveal a characteristic distribution pattern, as the slow Tf variants produced by TfD alleles are obviously more frequent in tropical than in non-tropical populations. Considering similar results in cattle and its interpretation by Ashton (1958, 1965), it is hypothesized, that the relatively high TfΓ frequencies in tropical biotops might be a selective adaptation to their special climatic conditions. In this connection an association between slowly moving transferrin proteins in man and tolerance to hotter climates — as could be found in…

MODIFICATION OF HUMIC SUBSTANCES FOR DEVELOPMENT OF MATERIALS FOR ENVIRONMENTAL TECHNOLOGIES

2019

Humic substances are high molecular weight refractory polycationites formed during decay of living organic matter and through biosynthesis of low molecular weight organic substances (metabolites or decay products of living organisms). Presence of many functional groups in the structure of humic substances determines their ability to interact with metal ions forming stable complexes and influencing metal ion speciation in the environment and mobility, behaviour and speciation forms in the environment. Presently humic substances are a product of industrial scale and quantities in amounts of hundreds of tons are produced. The aim of this study is to analyse derivatization possibilities of humi…

AbstractTriggering receptor expressed on myeloid cells (TREM)-1 plays an important role in innate immune responses and is upregulated under infectious as well as non-infectious conditions. In addition, a soluble TREM-1 variant (sTREM-1) is detectable in sera or bronchoalveolar-lavage fluids from patients. Currently, various studies are difficult to compare, since the methods of detection by enzyme-linked immunosorbent assays (ELISA) vary among different research groups. In this study, we compared three different s-TREM-1 specific ELISAs and identified individual assay characteristics finding notable differences in sTREM-1 concentrations in part depending on the employed buffers. Investigati…

Fundamentals and Applications of Cyclodextrins

2018

Cyclodextrins are natural oligosaccharides obtained from starch. They were discovered in 1891 by Villiers, and attracted major scientific and industrial interests from the late 1970s. Actually, cyclodextrins are among the most remarkable macrocyclic molecules with major theoretical and practical interest for chemistry and biology. Cyclodextrins belong to the family of cage molecules due to their structure, which is composed of a hydrophobic cavity that can encapsulate other molecules. Indeed, the most characteristic feature of cyclodextrins is their ability to form inclusion complexes with various molecules through host-guest interactions. Cyclodextrins and their derivatives have a wide var…

Time–carbonyl groups equivalence in photo-oxidative aging of virgin/recycled polymer blends

2004

AbstractThe photo-oxidation behaviour of polymers is strongly dependent on the initial amount of carbonyl groups along the chains. The growing use of recycled post-consumer polymers coming from products used outdoors and then photo-oxidised, both pure and blended with the same virgin polymer, gives rise to an unpredictable behaviour of weathering resistance of products made with these materials. The present work shows that the carbonyl group–exposure time curves can be shifted along the time axis to give a single generalised master plot. It is then possible to predict the formation of the new carbonyl groups by knowing only the initial amount of the same carbonyl groups. The same shift fact…
