ON THE BRUHAT G-ORDER BETWEEN LOCAL SYSTEMS ON THE B-ORBITS IN A HERMITIAN SYMMETRIC VARIETY
No full textFollowing Lusztig and Vogan, we study the Bruhat G-order on the set (Formula presented.) of rank 1 local systems on B-orbits in an Hermitian symmetric variety G/L. Supposing Φ irreducible, we obtain a complete combinatorial characterization of the order for Φ of type A, B, D, E and a partial characterization for Φ of type C
Is Sexual Dysfunction in Young Adult Survivors to the L‘Aquila Earthquake Related to Post-traumatic Stress Disorder? A Gender Perspective
No full textBackground: Mental disorders are frequently related to sexual dysfunction (SD) but scant data are still available on trauma-related disorders, particularly post-traumatic stress disorder (PTSD). Aim: To evaluate the relationships between SD and PTSD in 2009 L'Aquila (Italy) earthquake young adult survivors, with particular attention to gender differences. Methods: Five hundred twelve high-school senior students were assessed 21 months after exposure by the following: Trauma and Loss Spectrum–Self-Report (TALS-SR), for post-traumatic spectrum symptoms; Mood Spectrum–Self-Report (MOODS-SR) lifetime version, for mood spectrum symptoms (including SD-related symptoms). Descriptive and inferential statistics were adopted. Outcomes: TALS-SR and MOODS-SR scores were analyzed to evaluate PTSD- and SD-related symptoms. Results: Around 6.5% of subjects reported SD-related symptoms with males showing higher rates than females in each symptom, with a statistically significant difference in item n = 154 (...less sexually active). Survivors with symptomatological PTSD reported rates up to 10%, with higher ratio of endorsing at least one SD-related symptom than with NO-PTSD. Significantly higher total MOODS-SR SD-related symptom scores emerged in survivors with symptomatological PTSD than in those with NO-PTSD, and a 2-way ANOVA showed a significant main effect of symptomatological PTSD and gender and gender × PTSD interaction. Clinical Implications: SD-related symptoms are reported among young adult survivors to earthquake exposure and the number of symptoms is related to PTSD, particularly in males, suggesting the need for accurate evaluation. Strengths & Limitations: Strengths are the large sample of young adult survivors to a massive natural disaster; the long-time frame from exposure corroborating the role of PTSD; the assessment of symptoms specifically occurring after exposure. Limitations are as follows: the lack of a specific scale for SD; the self-report instruments other than clinical interviews, that may be less accurate; the lack of information on the presence of somatic illness and other mental disorders; the lack of a control group; the young age of the sample because of the lifetime sexual experiences of the subjects, in addition to the lack of a comparison measure of sexual functioning before the earthquake. Conclusions: Our results highlight relevant rates of SD-related symptoms in young adults exposed to the L'Aquila earthquake, particularly males and subjects with PTSD, suggesting SD may represent a specific male gender–related somatic complaint. Our results highlight the need for accurate investigation of SD in such population to improve clinical management and appropriate treatment. Carmassi C, Dell'Oste V, Pedrinelli V, et al.

Hydro-retention polyacrylamide gels amendment to potting media increase water availability
No full textThe aim of the paper is to clarify the advantages for the hard ornamental nursery stocks and for the environment derived from the addition of two commercial hydrophilic polyacrylamide gels to a peat/pumice (1:1 V/V) substrate. Also tomato crop was investigated. In both cases, the water absorption capacity of the two hydrophilic polyacrylamide gels was proportionally reduced with the presence of dissolved salts in the water. It was found that in the tested substrate an addition of 2 g L-1 of super-water-retention gel can increase the amount of retained water by about 130 g for each liter of substrate. However, only 40-50% of the higher amount of water retained by super-water retention was available for the crop. Under the operating conditions (drip irrigation with relatively saline water) the increase of water available for the crop (in the range 0-10 kPa) is only about 30 g for each gram of polymer added to the substrate. This higher substrate available water amount could increase the resistance of the plants to the absence of irrigation for 1-2 days. In conclusion, the addition of hydrophilic polyacrylamide gels to the substrate seems to have positive effects on plants, especially after the end of cultivation (selection and preparation of plants, packaging, storage, transport) and, probably, also during the early stages after transplanting in the customer's garden, where optimal irrigation could be not always guaranteed
Short Lecture "Phytochemical, nutritional, and mineral content of four edible flowers"
No full textThe consumption of flowers as food dates to ancient Greek and Rome and survives to the present day as part of the traditional cuisine of different countries [1]. The consumption of edible flowers (EFs) is significantly increased in the last few years, due to both their numerous healthy compounds and the heightened awareness of people to the food quality [1]. In this context four EFs were investigated to evaluate their aromatic profile and their nutritional value. The studied species were Dianthus chinesis L., Viola cornuta L., Fucsia regia (Vand. Ex Vell.) Munz and Cucurbita moschata Duchesne. p-Dimethoxybenzene (77.5%), cis-hexenyl acetate (31.2%) and decanal, non-terpene compounds, were the main constituents in volatile profile (by HS-SPME analysis) of C. moschata and D. chinensis, and F. regia, respectively. On the contrary V. cornuta was rich in terpenes mainly represented by myrcene (36.7%) and α-farnesene (34.5%). The extraction of the essential oil (EO) was carried out on C. moschata, D. chinensis, and V. cornuta. The EOs of the first two species maintained the prevalence of non-terpenes even though heneicosane (34.9%) and behenic alcohol (39.6%) becomes the principal ones, respectively, while Viola EO was rich in (E)-palmitoleic acid (31.3%). From the nutritional point of view, F. regia have the most interesting flowers, with the highest content of polyphenols, anthocyanins, calcium, iron, and zinc. D. chinensis contains the higher soluble sugars, and common C. moschata flowers contain high quantities of crude proteins, phosphorous, potassium and magnesium and low content of secondary metabolite
Could the addition of hydro-retention polyacrylamide gels into a substrate really increase its available water amount?
No full textThe aim of the paper is to clarify the advantages for the hard ornamental nursery stocks and to environment derived by the addition of two commercial hydrophilic polyacrylamide gels in a peat/pumice (1:1 V/V) substrate. In both cases, the water absorption capacity of the two hydrophilic polyacrylamide gels was proportional reduced with the presence of dissolved salts in the water. It was found that in the tested substrate an addition of 2 g/L of super-water-retention can increase the amount of retained water of about 130 g for each litre of substrate. However, only 40-50% of the greater amount of water retained by super–water retention was available for the crop. Under operating conditions (drip irrigation with relatively saline water) the increase of water available for the crop in the range (0- -10 KPa) is only about 30 g for each gram of polymer added to the substrate. This higher substrate available water could increase the resistance of the plants to the absence of irrigation for 1-2 days. In conclusion, the addition of hydrophilic polyacrylamide gels to the substrate seems to have positive effects on plants, especially after the end of cultivation (selection and preparation of plants, packaging, storage, transport) and, probably, also during the early stages after transplanting in the customer’s garden, where optimal irrigation could be not always guaranteed
