This study aims to evaluate the effectiveness of NTI-TSS splint (Tension suppression system- Inhibition trigeminal nociceptive) in the treatment of TMD (temporomandibular Disorder ) by using the EMG Electromyography. Fifteen patients have TMD were selected for this study. They were examined according to special examination form. EMG examinations for the masseter musclses before and after treatment by NTI splint for eight weeks every night were collected and anylysed.The results showed that : Turns increased from 375.3 to 423.18 left side and 358.7 to 408.87 right side, also amptiludes increased from 136.88 to 176.66 the right side, and 136.24 to 164.9 on the left side. It can be concluded that splint was effective in relieving symptoms and signs of TMD, and it found that NTI is comfortable splint , and easy to use by a Doctor and patient.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v illages (Happit, Al-Harah, Marg Moairban). This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride. In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used. The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer. The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the rural areas of Latakia city during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three villages (Happit, Al-Harah, Marg Moairban). This study has included the measurement of temperature T, pH, and determination of sodium, potassium, calcium concentrations, and sodium adsorbed rate (SAR). This study was based on the potentiometrictechnic using Ion Selective Electrodes (ISEs). SAR measurements have shown that there are clear differences between autumn and other seasons, and between treatment plants. The highest values was in the Happit treatment plant in all seasons and the highest value was (88.25 mg/L) in the autumn which is much larger than the allowable limit. The highest concentrations of sodium ion were in the autumn in all treatment plants (1002.67-7130.33) mg/L, which is off limits. As for the potassium ion concentration was highest (72.46 mg/L) in Happit treatment plant in the autumn. While calcium ion concentrations in Al-Harah treatment plant was exceeded (670.33-800.00) mg/L the allowable limit in all seasons except the summer. The statistical study has demonstrated and showed strongand sometimes weak correlation coefficient R2 so that gives clear indications about the sources of pollution.
