Abstract

An experimental study was carried out on a new design of a storage solar collector to verify its suitability for domestic use. The storage collector can be used as storage water tanks to replace the ordinary cubical or cylindrical tank commonly used in Iraqi houses. Experiments were carried out for both summer and winter weather conditions with and without hot water removal. The hourly system performance parameters were investigated systematically for all test conditions. These included the mean storage temperature and total stored energy. The day-long collection efficiency of the triangular collector under no load condition in winter (13-November-2004) was found to be 48.7% for a maximum mean storage temperature of 40.5 oC and a maximum hot water temperature at the tip of the collector of 65 oC. In summer (9-July-2004), the day-long collection efficiency was found to be 62.2% for a maximum mean storage temperature of 57 oC and a maximum hot water temperature of 70 oC. At continuous loading, the collection efficiency was 55.7% in winter, and 65.1% in summer. Also, in winter the maximum difference between the outlet and inlet water temperatures were 12 oC at 2 p.m. and 9 oC at the end of the day

Abstract

Thepresent work aims to enhance the thermal storage efficiency and thermal behavior for solar air heater integrated with cylindrical capsulessystem. The cylindrical capsule has diameter 50 mm and length 600 mm, placed in the crossflow of airstream.In this experimental study, a high specific heat of latent heat storage materials (PCM-paraffin wax) wereinvestedto increase the stored ability for sensible heat storage materials (pure sand). Three cases are testedunderconstant incident irradiation 1000Wm-2, in the first case cylindrical capsules packed with pure sand, second case cylindrical capsules packed with compound (sand+10% PCM) and third case cylindrical capsules packed with compound (sand+20% PCM), for both natural convection and forced convection with different mass flow rates (0.5 , 1.132 kg/min). The experimental results indicated that the compound (sand+20%PCM) gives the best thermal storage duration (380 min),with increase in outlet air temperature by approximately 5.6 % in forced convection with (0.5 kg/min) compared with pure sand (240 min). For forced convection with (1.132 kg/min), compound (sand+20%PCM) gives (355 min) thermal storage duration with increase in outlet air temperature by approximately 9.2 % compared with pure sand (220 min).Increase of mass flow rate leads to decrease the outlet air temperature period time of the discharge process.

Abstract

The stability and releasing profile of 2:1 core: wall ratio ibuprofen microcapsules prepared by aqueous coacervation (gelatin and acacia polymers coat) and an organic coacervation methods (ethyl cellulose and sodium alginate polymers coat) in weight equivalent to 300mg drug, were studied using different storage temperatures 40°C, 50°C ,60°C and refrigerator temperature 4°C in an opened and closed container for three months (releasing profile) and four months (stability study).It was found that, these ibuprofen microcapsules were stable with expiration dates of 4.1 and 3.1 years for aqueous and an organic method respectively.Aqueous prepared ibuprofen microcapsules were found more stable than those microcapsules prepared by organic method with activation energy (Ea) 4804.8 cal/mol and 5033.6 cal/mol of a drug respectively.The releasing percentage of ibuprofen for all microcapsules prepared by both methods was decreased as the storage temperatures increased, except for microcapsules prepared by aqueous method, which were found to be the same at 25-40°C as the standard one which stored at 25°C temperature, on the other hand , as the temperature decreased to 4°C (refrigerator ) of an open and closed container ,the amount of drug detected in microparticles is increased. These differences in the amount of drug released may be referred to the change in physical properties in polymer coats or in the amount of drug detected in a whole microcapsules.

تمت دراسة تأثير درجات الحرارة لكبسولات الايبوبروفين في درجات حرارة مختلفة (٦٠°م ,٥٠ °م، ٤٠ °م) واخرى بوضعها في درجة حرارة ٤°م) في وعائين مفتوح والأخر مغلق)على ثباتية وطريقة تحرر مادة الأيبوبروفين من النسبة( ٢: ١) للكبسولات المجهرية المحضرة بالطريقتين المائية (المغلفة بمادتي الجلاتين والصمغ العربي)والطريقة العضوية (لسليلوز الأثيل والجينيت الصوديوم ) بوزن يعادل ٣٠٠ ملغم من مادة الأيبوبروفين لمدة ثلاثة اشهر لدراسة تحرر الدواء واربعة اشهر لدراسة ثباتية الدواء .كان ثباتية تلك النسبة من الكبسولات المجهريه المحضرة بالطريقتين واضحا مع مدى صلاحية كل منهما١.٤ و ١.٣ سنوات للطريقتين المائية و العضوية على التوالي.ولقد وجد أن الكبسولات المجهرية المغلفة بالطريقة المائية أكثر ثباتية بسبب وجود المادة المصلبة للغلاف (الفورمالديهايد) التي تزيد من كفاءة التغليف وقابلية تحمله للحرارة العالية أو الرطوبة مع درجات حرارة منخفضة كان ذلك واضحا أيضا من خلال قلة طاقة تحفيز جزيئات الدواء.من جانب أخر وجد أن تحرر الدواء من تلك الكبسولات عند زيادة درجات حرارة الخزن تؤدي الى قلة في سرعة التحرر وعلى العكس بانخفاض درجات الحرارة ويعود ذلك الى التغيرات الفزياوية التي تحدث في المادة المغلفة للكبسولات المجهرية للأيبوبروفين والمشابهة لتحرر الأيبوبروفين من الكبسولات المجهرية المخزونة عند ٢٥°م عند خزنها في نفس تلك الدرجة, كما لوحظ تحرر الدواء من الكبسولات المجهرية المحضرة بالطريقة المائية لا تتغير مقارنة للنسبة الأصلية عند الدرجة ٢٥-٤٠°م.

Abstract

Background: It has been recommended that all materials returning from the laboratory be disinfected before placement in the patient’s mouth. Various adverse reactions have been reported when using disinfectant solutions with impression materials. Therefore, disinfection of dental cast may be effective in preventing cross infection. This study was carried out to evaluate the effect of storage time on the antimicrobial activity of chlorhexidine, sodium hypochlorite, and madacide-1 solutions and to test the effect of spray, immersion and incorporation techniques on their activities.Materials and Methods: Stone specimens were prepared in cylindrical blocks, under aseptic conditions, containing the three tested solutions applied by spray, immersion and incorporation methods. These specimens were stored for (1½h, 1 day, 3days, 7days, and 10days) and then tested by using disk-diffusion plate method to estimate the release of disinfectant solutions against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa,and Candida albicans. The zones of inhibition were measured with a ruler (in mm) after incubation, which was for 24h at 37°C aerobically.Results: The results showed that all microorganisms were sensitive to chlorhexidine and sodium hypochlorite while E.coli and P. aeruginosa were resistant to madacide. Also it was shown that chlorhexidine was more effective than madacide and sodium hypochlorite as a long acting disinfectant while sodium hypochlorite was the most effective as a short acting one.Conclusion: Immersion method had more inhibitory effect than the other methods representing (60 %) of all the tested specimens followed by incorporation method (25%) and the least percentage for spray method (15%).
