| ABSTRACT Kale is a vegetable that has high nutrition content, and balanced fertilization is essential to ensure high yield and quality of agricultural products. Curly kale, less known than regular leaf kale, is a new possibility for consumption. However, little is known about the influence of the type of fertilization on nutritional characteristics. This study aims to evaluate the influence of using organic fertilizers on the productivity, microbiological, and physico-chemical characteristics of Darkibor hybrid curly kale. The treatments consisted of three sources of organic fertilizers, one of organomineral fertilizer, and the control (without fertilization). The highest productivity was observed for kale that was treated with fertilizer in the... |

| Maintaining plants in the field for two consecutive crop cycles is one of the latest techniques used by strawberry growers to reduce production costs. The goal of this research was to evaluate the postharvest fruit quality of six strawberry cultivars produced for two consecutive seasons with the same plants. They were planted from May to July 2010 under low-tunnel and fruits were evaluated in two growing seasons (season 1= January, February, and March 2011 and season 2= August, September, and October 2011), totaling three harvests of each cultivar in each year season. Fruits were picked up randomly among 500 plants of each cultivar, organized into five replications of five fruits and kept for three days before analysis under refrigeration (average... |

| Shortly after strong rains or tropical storms, chlorophyll-a concentration (Chla), turbidity, and colored dissolved organic matter (CDOM) in the lagoon of New Caledonia may be tripled. This effect is visible as far as 50 km offshore. The Eastern Coast of New Caledonia is more impacted than the Western Coast because of its geomorphological structure. Higher frequency and intensity of the rains, and the dominance of highly erosive lateritic formations resulted from deep weathering of ultramafic rocks. At the deeper parts of the lagoon (> 20 m), increases of Chla, turbidity, and CDOM absorption can be detected by satellite imagery with their plumes extending off shore as a result of wind-driven circulation in the lagoon. Such -increases agree with the... |

| With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyze species’ potential resistance to future mining and perform meta-analyses on population density and diversity recovery after disturbances most similar to mining: volcanic eruptions at vents, fisheries on seamounts, and experiments that mimic nodule mining on abyssal plains. We report wide variation in recovery rates among taxa, size, and mobility of fauna. While... |

| 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... |

| Salt can be considered as the most widespread mineral in Eastern Africa and its recovery from the sea is a comparatively simple process given certain environmental conditions. The location of solar saltworks is controlled by the rainfall regime and the occurrence of suitable impermeable soils. These conditions occur from Ngomeni northwards to the Lamu area. Extensive saltworks have been established at the Gongoni-Fundi Is area and Kurawa. The total area dedicated to salt production is over 5,000 hectares that yield an average of over 170,000 tonnes of salt annually. The method of salt production utilised by the five established companies is very much the same throughout the area. Seawater is introduced into the ponds which are run in series. Slight... |

| Como parte del proyecto de implementación de la dieta macrobiótica en Cuba se valoró la situación de una arcilla italiana, empleada para enriquecer al agua potable con sales minerales, por una cubana similar (bentonita natural de Managua tipo 1). La caracterización minerológica, química y granulométrica de ambas arcillas fue similar. Se estudió el efecto de tres concentraciones de arcilla cubana en agua potable (0,1; 0,5 y 1 %) después de 24 h. Este tratamiento incrementó significativamente las concentraciones de sodio, magnesio y hierro y disminuyó las de calcio, cinc y cobre en el agua; todos los elementos cumplieron con las normas vigentes de agua potable. |

| The Republic of Equatorial Guinea consisted of a number of islands and islets, which include the volcanic island of Bioko in the Gulf of Guinea; the islands of Corisco, Elobey Chico, Elobey Grande, and Mbañe in Corisco Bay; the volcanic island of Annobón in the South Atlantic Ocean; and the Rio Muni enclave on the African mainland. In 1999 (the last year for which financial data were available), the gross domestic product of Equatorial Guinea was estimated to be about $696 million, and the population was estimated to be 442,700 (World Bank, July 2000, World development indicators database, accessed September 24, 2000, via URL http://www.worldbank.org/data/ countrydata/countrydata.html). The petroleum sector has dominated the country’s economy since 1996. |

| Flame absorption spectrophotometry was used to investigate the concentration and distribution of cadmium and lead in water, sediments and selected fish species in Makupa and Tudor creeks in Mombasa, Kenya between May 1997 and March 1998. The results were compared with those obtained in relatively less anthropogenically influenced areas along the Kenyan coast. The mean concentrations for Pb ranged from not detectable (nd) to 0.012 mg/l, 0.2 to 58.0 mg/kg and nd to 59.3 mg/kg in water, sediment and fish samples respectively. Cadmium concentrations in water were generally below detection limits, while in sediment and fish samples, they ranged from nd to 1.0 mg/kg and nd to 3.7 mg/kg respectively. Overall, Pb and Cd concentrations were low in the water column... |

| Because trace minerals are important not only for human nutrition, but for plant nutrition as well, plant breeding holds great promise for making a significant low-cost and sustainable contribution to reducing micronutrient deficiencies in humans, and may have important spinoff effects for increasing farm productivity in developing countries in an environmentally beneficial way. This paper describes ongoing plant breeding research that could increase the intake of bioavailable zinc from food staple crops among vulnerable populations in developing countries. The three most promising plant breeding strategies to achieve this goal are (1) increasing the concentration of zinc in the plant, (2) reducing the amount of phytic acid (a strong inhibitor of zinc... |

| Resource rents represent a return to the community for the exclusive use of resources and therefore are quite distinct from the recovery of governmental regulatory or operating costs. While the current framework for resource rents in Australian primary industries is providing financial benefit for Australian governments, it is uncertain whether the current policy settings are providing an appropriate community return. This paper discusses the theory underpinning resource rents and conducts a multijurisdictional comparison focusing on the minerals and fisheries industries to aid analysis of the role resource rent taxation plays in the existing management of Australian primary industries. |

| This study aimed at evaluating the effect of dietary calcium levels and the replacement of calcium sources with different particle size compositions on the performance and egg quality of brown layers in their second egg production cycle. A randomized block experimental design was applied with 12 treatments in a 3x4 factorial arrangement: three calcium levels (2.6, 3.2, 3.8 %) and four combinations of calcium sources (1- 100% fine limestone (FL), 2- 50% FL + 50% coarse limestone (CL), 3- 50% FL and 50% oyster shell (OS), 4- 50% FL and 25% CL+ 25 %OS), with six replicates of eight birds each. Calcium sources were analyzed for geometric mean diameter (GMD) and in-vitro solubility. The following performance and egg quality parameters were evaluated: egg weight... |
