The paper studies accessory Cr-spinels from deep drill holes crossing the Nude-Poaz massif, which is a part of the Monchegorsk mafic-ultramafic layered complex (2.5 Ga, Kola Peninsula, Russia). Cr-spinels occur as two morphological types that differ in their chemical composition, i.e., Cr-spinels of the first type are more aluminous, while Cr-spinels of the second type are more ferruginous and titaniferous. Cr-spinels of the Nude-Poaz massif are characterized by a Fe-Ti trend known for layered intrusions in the world. Cr-spinels of the Nude-Poaz massif quite clearly differ in composition from chromites of the Sopcheozero deposit: they are more ferruginous and less chromous. The specific composition of Cr-spinels in rocks of the Nude-Poaz massif can be correlated with the sequence of the magmatic phases intrusion.

‘What have volcanoes done for us?’ outlines how humans have benefited from volcanoes. Volcanism has helped make the planet as it is today, by contributing to the chemical composition of the atmosphere and oceans. Volcanoes provide rich, fertile environments for wildlife and agriculture. Ultimately, volcanoes have been essential for the evolution of the biosphere, the emergence of humanity and human civilization, and for the flowering of culture. However, volcanoes across the world are increasingly being exploited for tourism, quarrying, deforestation, and urbanization. They also pose a hazard, one that increases as burgeoning human populations encroach ever closer. The chapter then looks at methods of monitoring and mitigating volcanic hazards.

Available Information

India occupies 2nd position in the world with a total fruit production of 42 million tonnes. Papaya (Carica papaya) fruit production in India is 1.3 million tonnes. After extraction of juice from fruit, around 25-30% of the processed fruit is left as waste containing skins and seeds, called as papaya pomace. Generally this goes as a waste causing environmental pollution and if utilized properly will contribute to national economy and reduce pollution effect. Available information on chemical composition and utilization of papaya skins in feeding growing pullets (Fouzder et al., 1999) indicate the potential value of papaya pomace for animal feeding. In view of paucity of information on papaya pomace utilization in animal feeding, an attempt was made to study the effect of inclusion of varying levels of papaya pomace in concentrate mixtures on the nutrient utilization in native male buffaloes.

Alkaline Massif

The Lovozero Alkaline Massif intruded through the Archean granite-gneiss and Devonian volcaniclastic rocks ca. 360 Ma ago and formed a large laccolith-type body. The lower part of the massif (the Layered complex) is composed of regularly repeating rhythms: melanocratic nepheline syenite (lujavrite, at the top), leucocratic nepheline syenite (foyaite), foidolite (urtite). The upper part of the massif (the Eudialyte complex) is indistinctly layered, and lujavrite enriched with eudialyte-group minerals (EGM) prevails there. In this article, we present the results of a study of the chemical composition and petrography of more than 400 samples of the EGM from the main types of rock of the Lovozero massif. In all types of rock, the EGM form at the late magmatic stage later than alkaline clinopyroxenes and amphiboles or simultaneously with it. When the crystallization of pyroxenes and EGM is simultaneous, the content of ferrous iron in the EGM composition increases. The Mn/Fe ratio in the EGM increases during fractional crystallization from lujavrite to foyaite and urtite. The same process leads to an increase in the modal content of EGM in the foyaite of the Layered complex and to the appearance of primary minerals of the lovozerite group in the foyaite of the Eudialyte complex.

Pistachio (pistachio vera) is from Anacardiaceae family. According to the FAO (2003) report, Iran is the largest pistachio producer in the world (more than 310,000 tons). The most three important exported pistachio nuts of Iran are Ohadi, Akbari and Kaleghuchi (Mohammadi, 2005). About 150,000 tons in DM of pistachio by-product (PB) is produced from dehulling process in Iran, annually. This by-product is mainly consisted of pistachio hulls (PH), and then peduncles, leaves and a little amount of mesocarp and kernels. In this experiment the chemical composition, Total Phenolic Content (TPC) and tannin amount of PB and PH of Ohadi, Kaleghuchi and white varieties were determined; also, In Vitro Dry Matter and Organic Matter Digestibility (IVDMD and IVOMD) were measured.

Since Spring 1983, the Pic du Midi and Toulouse Observatory has put the Gentilly 60-cm telescope at the disposal of amateurs. There was an initial experimental trial in 1982, and an amateur Programme Committee was set up in 1983. The “T.60 Association” took over the whole of the operation in 1984. So far, five hundred different amateur astronomers have used the equipment. The prime advantage of the T.60 is its site at the Pic du Midi, 2877 m altitude, one of the best observing sites in the world. By giving new facilities to amateurs, the T.60 offers considerable scientific and educational rewards. Work that has already been carried out includes: determination of H-R diagrams of faint clusters, spectra of planetary nebulae, polarimetric and interferometric studies of nebulae, photoelectric and visual studies of variable stars, research into the chemical composition of faint stars, and observations of mutual phenomena of Jupiter’s satellites.

Harmful sewage sludge generated from wastewater treatment plant being disposed to landfill has long caused major anxiety in local municipalities around the world. In line with the concept of sustainable development practice being adopted around the world, more efforts has looked deeper into ways to reuse this waste material and one of it was the ash generated from this material. This paper review the use of sewage sludge and sewage sludge ash (SSA) in construction and agriculture industry through a multi-faceted review of previous researches done in various industries. Besides reducing the amount of waste in landfill, this solution can also contribute to the reduction of natural resources consumption. It examines in detail how the various burning temperature can affect the sewage sludge ash as well as the potential usage of this ash in asphalt, concrete and cement mixture, soil stabilization and agriculture either as a substitute material, or as a raw and enhancement material. The various chemical composition in this ash enable the SSA to be used in application in multiple industry as each of the respective chemical composition bring enhancement to the end product respectively.

Biodegradation Efficiency

ABSTRACT Results of studies performed all around the world on bioremediation techniques are not often comparable because they have been performed through different methodologies. To address this problem, several organizations have combined their efforts to define a common methodology to assess bioremediation techniques’ efficiency through field experiments. To confirm the validity of this protocol, a 9 month experiment was performed on oiled plots on a sheltered estuarine beach in France. In this experiment, biodegradation efficiency was assessed though multiple analyses (chemical and microbiogical) including changes in chemical composition of the residual oil.
