The properties of tungsten make it ideal for use as a plasma facing surface in the divertor of large plasma machines such as JET and ITER. However, the intense heat and particle fluxes …
Autonomy and Relatedness in Adolescence and Emerging Adulthood: Relationships with Parental Support and Psychological Distress
2014
Autonomy and relatedness are fundamental needs both in adolescence and in emerging adulthood which are affected by parental support and are linked to children’s psychological distress. The study investigated autonomy and relatedness in late adolescents and emerging adults living in Italy, analyzing the relationships with perceived parental support and psychological distress. Self-report data were collected from a sample of 325 Caucasian adolescents and emerging adults (males = 41 %) ranging in age from 17 to 26 years and living in Sicily (southern Italy). Results showed that: (a) both autonomy and relatedness were positively predicted by parental support to these needs, (b) perceived suppor…
Bio-agronomic behaviour and an initial study of the energy properties of Carthamus tinctorius L. and Brassica carinata A. Braun crop residues
2009
In recent years, the agro-energy sector has become of considerable importance, both as a vehicle towards realising the objectives established by the Kyoto protocol and as a means of meeting the ever increasing demand for energy. Biofuels represent one of the most promising forms of renewable energy due to their wide range of applications, although limited by the fact that they do not compete on a cost level with fossil fuels. This study takes a look at the bio-agronomic response and the physical and energetic properties of crop residues of a selection of Carthamus tinctorius L. and Brassica carinata A. Braun accessions in order to evaluate integrating oilseed production with lignocellulosic…
Regulation of Phenotypic Switching and Heterogeneity in Photorhabdus luminescens Cell Populations.
2019
Phenotypic heterogeneity in bacterial cell populations allows genetically identical organisms to different behavior under similar environmental conditions. The Gram-negative bacterium Photorhabdus luminescens is an excellent organism to study phenotypic heterogeneity since their life cycle involves a symbiotic interaction with soil nematodes as well as a pathogenic association with insect larvae. Phenotypic heterogeneity is highly distinct in P. luminescens. The bacteria exist in two phenotypic forms that differ in various morphologic and phenotypic traits and are therefore distinguished as primary (1°) and secondary (2°) cells. The 1 cells are bioluminescent, pigmented, produce several sec…
Cadmium effects on development and reproduction of Oncopeltus fasciatus (Heteroptera: Lygaeidae)
2004
Newly hatched nymphs of the insect Oncopeltus fasciatus were exposed to various concentrations of CdCl2 administered in drinking water until the end of adult life. Significant nymphal mortalities were observed at concentrations above 30 mg Cd/l (corresponding to the LC50). The duration of the nymphal stages increased in proportion to the Cd concentration; at the lowest Cd concentration of 10 mg Cd/l, the median duration was significantly prolonged by one day, while at the highest concentration of 100 mg Cd/l it was increased by 10 days over the control group. The weight of newly emerged adults lineally decreased with Cd concentration, being reduced to half the weight of controls at 100 mg C…
Influence of Culture Conditions on In Vitro Asymbiotic Germination of Anacamptis longicornu and Ophrys panormitana (Orchidaceae)
2021
This study is the first approach to in vitro asymbiotic germination of two species of Sicilian threatened terrestrial orchids, Anacamptis longicornu and Ophrys panormitana. Seeds were collected in the wild and cultured in two different media—Orchimax medium (OM) and Murashige and Skoog (MS)—and exposed to different photoperiods and temperatures to evaluate the best conditions for the specific stages of development. The germination of A. longicornu was very high on OM (95.5%) and lower on MS medium (21.4%), whereas O. panormitana germinated only on OM medium, with significantly lower percentages (12.0%), compared with A. longicornu. This difference is caused by variation in quality and quant…
Proteomics of foodborne trematodes
2011
Abstract Food-borne trematodiases are among the most neglected tropical diseases, not only in terms of research funding, but also in the public media. The Trematoda class contains several species identified as the causal agents of these diseases whose biological cycle, geographical distribution and epidemiology have been well characterised. The diagnosis of these diseases is based on parasitological techniques and only a limited number of drugs are currently available for treatments, most of which are unspecific. Therefore, in-depth studies to identify new and specific targets for both effective diagnosis and treatments are urgently needed. Currently, little molecular information is availab…
Fourth Graders' Social Standing with Peers: A Prospective Study on the Role of First Grade Physical Activity, Weight Status, and Motor Proficiency
2010
We prospectively examined the role of physical activity involvement, weight status, and motor functioning capability in 1st grade for social status among other pupils in class in the 4th grade. Our sample included 80 Norwegian 1st grade pupils (Girls N = 44; Boys N = 36). 1st grade motor proficiency and objectively measured physical activity, but not weight status was predictive of 4th grade social standing among pupils in class as measured by socio‐metric status. Interaction findings also revealed that 1st grade healthy weight children being proficient in the motor domain benefit more in terms of their social standing among peers in 4th grade than do 1st grade overweight but equally motor …
Metabolic syndrome, insulin resistance and sleepiness in real-life obstructive sleep apnoea.
2011
The metabolic syndrome shows a variable prevalence in obstructive sleep apnoea (OSA), and its association with insulin resistance or excessive daytime sleepiness in OSA is unclear. This study assessed the following in consecutive patients with newly diagnosed OSA: 1) the prevalence of metabolic syndrome; and 2) its association with insulin resistance and daytime sleepiness. Metabolic syndrome (National Cholesterol Education Program Adult Treatment Panel (NCEP- ATP) III criteria), insulin resistance (Homeostatic Model Assessment (HOMA) index, n5288) and daytime sleepiness (Epworth Sleepiness Scale) were assessed in 529 OSA patients. The prevalence of metabolic syndrome was 51.2%, which incre…
Obstructive sleep apnea and chronic kidney disease: open questions on a potential public health problem
2018
To determine the relationship between obstructive sleep apnea (OSA) and chronic kidney disease (CKD). Previous population studies of the association are sparse, conflicting and confined largely to studies of administrative data.Cross-sectional analysis in unselected participants of the Men Androgens Inflammation Lifestyle Environment and Stress (MAILES) study, aged40 years. Renal data were available for 812 men without a prior OSA diagnosis who underwent full in-home polysomnography (Embletta X100) in 2010-2011. CKD was defined as an estimated glomerular filtration rate (eGFR)60 mL/min/1.73m2 or eGFR≥60 and albuminuria (albumin-creatinine ratio ≥3.0 mg/mmol).CKD (10.5%, n = 85 [Stage 1-3, 9…
