tissue Magnesium Content and histopathological changes in non survivors of aluminium phosphide poisoning
Journal of Association of Physicians of India, 1995Co-Authors: S B Siwach, D Sharma, A Dua, R Sharma, R K MehlaAbstract:The study was conducted in 30 non-survivors of Aluminium Phosphide poisoning and similar number of age and sex matched controls (fatalities as a result of road side accidents, head injury, etc). Magnesium Content was estimated in brain, heart, stomach, kidney, liver and lung using atomic absorption spectrophotometer. It was found that tissue Magnesium levels were not significantly different (p = NS) when comparison was carried out between controls (Group II) and Patients who were not given Magnesium as part of treatment (group IB). However Magnesium levels in different organs of patients who received Magnesium as part of treatment were found to be significantly higher (group IA)(P < 0.01) in comparison to controls as well as patient group not treated with Magnesium sulphate. Significant histopathological changes were observed in almost all the organs. The changes seem to be the result of direct tissue damage by phosphine rather than shock and anoxia which occurred in all these cases.

serum tissue Magnesium Content in patients of aluminium phosphide poisoning and critical evaluation of high dose Magnesium sulphate therapy in reducing mortality
Journal of Association of Physicians of India, 1994Co-Authors: S B Siwach, P Singh, S Ahlawat, D SharmaAbstract:: Role of high dose Magnesium sulphate therapy was evaluated in 50 patients of Aluminium Phosphide (AIP) poisoning. Simultaneously serum and RBC Magnesium levels were studied in these patients at six different points within first 24 hours. In non-survivors Magnesium Content of various tissues (brain, stomach, kidneys, liver, lungs and heart) was also estimated. Magnesium estimation (tissue as well as serum) was done using atomic absorption spectrophotometer. No significant difference was found in dose related mortality rates in patients treated with and without Magnesium sulphate. The immediate causes of death in these patients included intractable shock, shock coupled with arrhythmias and adult respiratory distress syndrome (ARDS). Serum as well as RBC Magnesium Content was within normal range at all the six points (0, 1, 3, 6, 12 and 24 hours after arrival in hospital). Tissue Magnesium Content of various organs (in non-survivors) was more (p < 0.01) compared to that of corresponding organs in controls (accidental deaths). No significant alterations were seen in other serum electrolytes (Na, K, Ca, PO4). The data confirmed that neither there was any evidence of hypomagnesemia in these patients nor Magnesium sulphate therapy improved survival. Survival can be improved (to some extent) with continuous cardiac monitoring and use of appropriate anti-arrhythmic agents. However, imposition of stringent restrictions on the free supply of AIP and caging of tablets in plastic packs with holes and spikes may yield better results in preventing AIP poisoning rather than treating these patients.

Influence of Magnesium Content on the corrosion resistance of the cut-edges of Zn–Mg-coated steel
Corrosion Science, 2015Co-Authors: F. Thebault, B. Vuillemin, Roland Oltra, Christian Allely, K. Ogle, Olivier HeintzAbstract:Abstract The ability of Zn–Mg coatings (with Magnesium Content between 5.8 and 15.5 wt.%) to protect steel sheets has been evaluated with local electrochemical techniques (scanning vibrating electrode technique, microcapillary electrochemical cell) and rotating disk electrode, and compared with the corrosion protection afforded by a pure zinc coating. From immersion tests of coated steel cut-edges, it is observed that alloying zinc with Magnesium leads to a decrease of the galvanic current between the coating and the steel surface, and to an improvement of the steel corrosion resistance after a drying period, due to the presence of Magnesium in the corrosion products.

COW DUNG MANAGEMENT ON THE CALCIUM AND Magnesium Content AND TOTAL MICROBIAL POPULATION IN THE NORTHERN GUINEA SAVANNA OF NIGERIA
2013Co-Authors: J. Tanimu, Y. TanimuAbstract:The effect of time and duration of storage of cow dung on the calcium and Magnesium Content and total microbial population was investigated for two years in Samaru, Northern Guinea Savanna, Nigeria. The treatments were composed of 0, 4, 8 and 12 weeks of cow dung storage in the field after one month of composting and a control treatment. The results showed that, the use of cow dung immediately after composting in May (4 weeks) significantly (P < 0.05) released more of Ca and Mg, however after field storage the June (0 week) treatment appeared to be better. The total microbial population, immediately after composting showed bacterial and fungal populations to be more in the June (0 week) treatment, but if stored in the field before use the April (8 weeks) treatment gave a significantly (P < 0.05) higher population of the microbes.

Assessment of Some Handling Practices on Cow Dung: Calcium and Magnesium Content and Total Microbial Population in the Northern Guinea Savanna of Nigeria
2012Co-Authors: J. Tanimu, Y. TanimuAbstract:The handling practices of cow dung were examined in two (2003 and 2004) seasons to determine their effects on the Calcium and Magnesium Content and the microbial population in Northern Nigeria. The experiment consisted of four treatments (surface heaped uncovered, surface heaped covered and pit covered) and a control (untreated). The results revealed that, subjecting the cow dung to different handling practices significantly (P < 0.05) increased values of Calcium and Magnesium and the total bacterial and fungal populations, compared to the control. At termination of composting of the cow dung, the heaped uncovered method gave significantly (P < 0.05) higher values of Calcium and Magnesium in the two years, while after field storage, it was the heaped covered method that gave significantly (P < 0.05) higher values of the Calcium and Magnesium for the two years. In each case where the nutrient Content (Ca and Mg) was high, the microbial population of bacteria and fungi was also high. It is therefore concluded that, the high Calcium and Magnesium Content of cow dung was directly related to the high population of bacteria and fungi. It is therefore recommended based on this work, that cow dung should be used immediately after composting using the heaped uncovered method, while the heaped covered method is recommended if it is to be used after field storage.

Effect of Magnesium Content on thermal and structural parameters of Al–Mg alloys directionally solidified
Journal of Materials Science, 2010Co-Authors: Jean Robert Pereira Rodrigues, Mirian Lourdes Noronha Motta Melo, Rezende Gomes SantosAbstract:In this study, the influence of Magnesium Content on thermal and structural parameters during the unsteady-state unidirectional solidification of Al–Mg alloys is analyzed. Using a special device, Al–Mg alloys containing 5, 10, and 15 wt% Mg were submitted to unidirectional solidification. Using a data acquisition system, the temperature variations along the casting during solidification were measured. From these results, the variations of solidification parameters as growth rate of dendrite tips, thermal gradient, cooling rate, and local solidification time were determined. The variation of global heat transfer coefficient at metal/mould interface was estimated through the adjustment of experimental temperature variation close to the interface and numerical predictions. Primary and secondary dendrite arms spacing variations during solidification were measured by optical microscopy. From these results, comparative analysis were developed to determine the influence of Magnesium Content.
