| Melatonin is an environmentally friendly-molecule with a potent free radical scavenger and antioxidant capacity. Two pot experiments were conducted during two successive winter seasons (2011/2012 and 2012/2013) at the wire-house of the National Research Centre, Dokki, Cairo, Egypt to study the potentiality of melatonin (100 mM and 500 mM) in alleviating the harmful effect of diluted seawater at a relatively low and high concentrations (3.85 dS/m and 7.69 dS/m, respectively) on the performance of faba bean plants. The results revealed that irrigation of faba bean plants with diluted seawater reduced growth parameters (plant height, leaves number/plant, fresh and dry weights of plant), relative water content (RWC), photosynthetic pigments (chlorophylls a, b... |

| This experiment was conducted to determine the requirement of available phosphorus (aP) for pigs kept in hot environment. Seventy-two pigs (36 castrated males and 36 females) with initial weight of 15.10±0.31 kg were allotted in a completely randomized block design with six treatments (0.107, 0.214, 0.321, 0.428, 0.535, and 0.642% of aP), six replicates and two pigs (1 castrated male and 1 female) per experimental unit. Pigs were kept in a hot environment with temperature of 34.1±0.8 ºC. The levels of aP influenced the daily weight gain, which increased quadratically up to the estimated level of 0.477%, and feed conversion, which improved quadratically up to the estimated level of 0.457%. The levels of aP also influenced the content of phosphorus in the... |

| Copao (Eulychnia acida Phil.) is an endemic arborescent cactus restricted mainly to the semi-arid Coquimbo Region (29°54'28" S, 71°15'15" W), Chile. The area of distribution is from sea level to 1200 m.a.s.l. The edible fruit called rumpa is generally round, with green or pink peel and small scales on its surface, showing wide variability in size and weight. The aim of this work was to characterize the rumpa harvested in January 2009 and 2010 in three sectors of Coquimbo Region to determine chemical and nutritional composition in three fractions: pulp with seeds, juice, and peel. The research showed that this fruit is a good natural source of mainly soluble dietary fiber, which has a jellied texture and is present in the three fractions analyzed: 2% for... |

| The Mineralogical Museum of the St.-Petersburg State University is housed in the building of the ‘Twelve Colleges’. It accomodates some of the most ancient mineralogical collections of Russia. The university mineral collection took its origin from a Mineralogical Cabinet of a Teacher’s Seminary, which was established in 1783. J.G. Georgi (1729-1802) was commissioned to collect minerals for the institute and he can be considered the founder of the museum. The history of enlarging and enriching the mineral collection is inextricably related with 19th century celebrities and their private collections. At the beginning of the 19th century, when the Seminary was transformed into a Pedagogical Institute, the collection of the Mineralogical Cabinet included in... |
