This work presented in the thesis pertains to the design of a pilot plant based on new blasting explosives developed from decanted Trinitrotoluene (TNT). Disposal of life-expired and unwanted munitions is a great challenge across the globe. In the past, these unserviceable explosives were disposed of through conventional disposal techniques such as Open Burning/ Open Detonation (OB/OD), sea dumping, underground demolition, incineration and biological degradation. Production of poisonous and toxic gases such as NOx, COx, etc. during these disposal techniques have always been a great concern for Environmental Protection Agency (EPA). Besides, labour cost for the preparation of disposal pits, fuel requirement for shifting of explosives to munition disposal sites and use of large quantities of serviceable explosives during disposal of these unwanted munitions makes these techniques most uneconomical, unsafe and unfriendly for the environment. In order to curtail all these practices, decanting of explosives through decanting plant were carried out for different munitions. All decanted explosives, particularly decanted TNT, were disposed of further through open air burning. In the present research work, efforts have been made to reutilize the decanted TNT. For this purpose, various ingredients such as oxidizers, stabilizers and additional fuels have been added to the decanted TNT to convert it into viable blasting explosive compositions. Laboratory scale experiments using decanted TNT and other ingredients such as calcium ammonium nitrate (CaAN), commercial grade wax and calcium carbonate (CaCO3) have been carried out to make different blasting compositions. All the newly formulated compositions were characterized through different analytical techniques such as Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Thermogravimetry/ Differential Thermal Analysis (TG/DTA) and Fourier Transform Infrared (FTIR) to study their morphological and thermal cum kinetic properties. Simultaneously, Horowitz and Metzger method is used for calculation of activation energy (Ea) and enthalpy of different samples. Once all compositions were certified for their future use, velocities of detonation (VOD) measurements were conducted. Besides, stability tests, the density of all these compositions were also measured. In order to translate the laboratory scale compositions into useable blasting explosives, a pilot scale plant has been designed using PTC-Creo Parametric 3D modeling software. Similarly, simulation of the design was carried out through Aspen Plus® V8.4 simulation software. Based on the successful simulation and design results, a state-of-the-art, safe, feasible and environment friendly semi-automatic pilot scale plant has been fabricated and installed for the conversion of decanted explosive into blasting explosives for civil and military applications. Main components of the plant include double jacketed mixing drums, brass-made mashing roller, 5 Horse Power (HP) motor, vertical gear box and fume discharging unit having explosives production capacity of about 10kg/ hour per batch. All the safety parameters required during manufacture, filling and formulation of explosives have been ensured to avoid any untoward situation. Functional test of this plant was performed using dummy explosive materials having almost similar compositions. Subsequently, blasting explosive samples were produced utilizing decanted TNT and other suitable ingredients. To ascertain their performance, VOD tests of all newly formulated blasting explosives have been performed. It is worth mentioning that the resultant VOD of all the samples fall between 2600-4400 m/s which makes it the most suitable product for use in blasting applications such as mining, quarrying, underwater blasting, etc. In a nutshell, the present research work not only provides an opportunity for riskfree reutilization of decanted TNT where new products are easily manufactured, cheap in cost and safe in handling; but EPA concerns regarding emissions of toxic gases into the atmosphere are also amicably addressed through reutilization of unwanted TNT that will ultimately enhance Carbon Credit Ratings of Pakistan around the globe.

Interactive Studies on Hyperthyroidism, Hypothyroidism and Euthyroidism With Serum Lipid Profile, Creatinine and Alanine Amino Transferase

Diseases of the thyroid are common, affecting some 5% of the population, predominantly females. The thyroid axis is involved in the regulation of cellular differentiation and metabolism in virtually all nucleated cells, so that disorders of thyroid function have diverse manifestation. The pathophysiology of many thyroid diseases relates to TSH, T3 and T4. The TSH level is the most sensitive index of thyroid function. Hyperthyroidism especially as Thyrotoxicosis is the hyper-metabolic condition connected by way of eminent levels of free thyroxine (fT4), free triiodothyronine (fT3), or both of them. Hypothyroidism is an ordinary endocrine disorder ensuing from shortage of thyroid hormone. It is frequently the key progression in which the thyroid glands fabricate inadequate quantity of thyroid hormone. As these disorders may severely affect the patients at almost all levels of physical, mental, metabolic and social conditioning that could be extendable to even death status. Not only this, but these diseases may become long lasting and can bring bad impact on socio-economic status of their concerned families as well. To elucidate some of these major relations, while keeping in view the various selected demographic details (age, gender and locality etc) of included patients, this study aims at understanding the relation between thyroid dysfunction and functioning of certain major organs of human body i.e kidney and liver. It also aims at studying the influence of thyroid mal function on lipid profile including total cholesterol, triacylglycerol, LDL-C, HDL-C, VLDL-C. To execute, the study was ethically permitted by the ethical committee of Post Graduate Medical Institute (PGMI) Hayatabad Medical Complex Peshawar, xiii and was conducted in the Institute of Radioactive Nuclear Medicine (IRNUM) Peshawar, Pakistan. Blood samples of all included patients were analysed in Pakistan Medical Research Centre (PMRC), Khyber Medical College Peshawar, Pakistan. A total of 600 cases were chosen of 214, 195 and 191 each Euthyroid, Hypothyroid and Hyperthyroid patients, respectively from the Institute of Radioactive Nuclear Medicine (IRNUM) Peshawar, Pakistan. A well designed proforma was used to record patients sample No, name, age, sex, address, clinical diagnosis etc: The blood samples of all included patients were collected, followed by their analysis for required parametric evaluation included with complete lipid profile, serum creatinine and alanine transaminase in comparison to T3, T4 and TSH of all respectively assessed patients. During this study, the results obtained regarding the demographical aspects of the patients revealed that female gender has categorically significantly high percentage of occurrence of thyroid abnormality as compared to male (75.8 % vs. 24.2 %). Similarly, it has been observed that in case of euthyroidism, hyperthyroidism and hypothyroidism, the comparative number of cases of occurrence between female vs male gender were 162 vs. 52, 158 vs. 37 and 155 vs. 56, respectively. In consideration to the nature of abnormality of thyroid disorder, it has been observed that patients of euthyroidism i-e., 214 were more than 191 and 195 for hypothyroidism and hyperthyroidism, respectively. Results regarding locality distribution of the patients depicted that majority of those belongs to the local population of Peshawar and Charsadda region. Importantly, the data showed that significant percentage of patients was from Afghanistan. xiv Furthermore, results regarding age distribution of the included subjects showed that these thyroid disorders mostly exist among age group of 31-40 years, which may be the most effective age limit for productivity and where the above mentioned hormonal changes and associated activity become at peak. Results regarding locality distribution of the patients depicted that majority of those belongs to local population of Peshawar and Charsadda region. In consideration to the impact of type of thyroid disorder on the level of respective parameter of lipid profile, the results revealed that there was reduction of blood cholesterol level and HDL in patients suffering from hyperthyroidism as compared to euthyroidism. The Aims and objectives of the study were to evaluate the prevalence of thyroid dysfunction in male and female subjects of different age groups and to establish the relation between locality of the considered patients and thyroid disorder. The specific objective is to study the association between sub clinical hypothyroidism and hyper cholesterolaemia, and to determine the link of different degrees of thyroid dysfsunction with kidney and liver function. The data were finally imported in SPSS version 20.0 for analysis. The student’s “t” test is being used to find out the significance between two values, in various diseased groups. Frequencies, p-value, and other descriptive analysis were computed to calculate the mean and standard deviation of different parameters. Coefficient of correlation (r) was also calculated using SPSS version 16.00 as a soft ware statistical package. The correlation value (r-value) was calculated between two parameters i-e EU, hyper, and hypo with serum Lipid profile, CTN and serum ALT respectively.
