The new mineral, the iron analogue of monticellite, occurs in melilite-nephelinite Iava from Mt. Shaheru, Belgian Congo, associated with melilite, nepheline, clinopyroxene, kalsilite, gdtzenite, combeite, sodalite, magnetite, perovskite, apatite, hornblende, biotite, and an unident i f ied mineral . Analysis gave SiO2 32.77,TiO20.23, AIzOa0.26, Fe2Oa 0.66, FeO 29 34, MnO 1.65, MgO 4.95, CaO 29....
Regional exploration and identification of anomalies can be done by geochemical data resulted from stream sediments. In this paper, fractal methods of concentration-number and concentration-area were used for regional studies, and abnormalities of elements including gold, arsenic, bismuth and mercury were studied. Statistical processing of these elements took place with the help of 1063 samples...
In general, provenance analysis has developed over the past 70 years into an enormously important tool in sediment investigations, both enabling solving earth science questions basic research and practically applying it to mineral exploration [...]
An investigation was carried out based on the survey of the problems and prospects of fish fry trade in Jessore district in Bangladesh. The survey was conducted on 82 nursery operators and 50 fry traders from different parts of the country. The objective of the study was to know the present status of the trade, identify the problems associated with the business, assessment of aids needed for th...
Edema and cardiovascular dysfunction occur in vertebrates exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) during early development. This study examined cytochrome P4501A (CYP1A) induction in endothelium and its possible association with mortality due to the edema and vascular effects of TCDD in lake trout early life stages. Lake trout (Salvelinus namaycush) eggs were injected at 24-50 hr ...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
The aim of this study was to identify various sulfidic mineralized zones in the Ghare-Tappeh Cu deposit (NW Iran) based on geo-electrical data including induced polarization (IP) and resistivity (RS) using the concentration-volume (C-V) and number-size (N-S) fractal models. The fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. B...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
