تعتبر عملية تبييض الأقمشة القطنية من العمليات الحساسة و المهمة في المعالجات الكيميائية الرطبة للأقمشة القطنية, و لا تقل المرسزة أهمية عنها و ذلك في الحالات التي يعتبر إجرؤها ضروري, و لكن من مشاكل هذه المعالجات الزمن الطويل و استهلاك الطاقة, إلا أن طاقة الأمواج فوق الصوتية تساهم في الحد من مشاكل هذه المعالجات أو تقليلها.
Bleaching process of cotton fabrics consider an important and sensitive operations in wet chemical treatments of cotton fabrics, mercerization is not less important than them and that in cases in which is made necessary, but from the problems of these processes are long time and consumption of energy, but the ultrasound energy contribute to reduce these problems.

In this study we used ultrasonic technology as a means of
enhancing dyeing process efficiency of polyester fibers with
disperse dyes, which had frequency 42kHz and, we studied the
behavior of dye when the polyester dyed with (US) and with
traditional dyeing methods (without US).
In this research, we did the optical spectral study for using
ultrasound energy in dyeing wool fibers using acid dyes. That we
dyed wool fibers using both traditional dyeing and ultrasound
techniques by using three acid dyes from different firms.
The results of exhaustion percentage of the dye had been compared "the total moving dyes from a solution to fibers after dyeing".
The exhaustion rate of some dyes increased by a large proportion
but the effect on the fastness of the light, rubbing and washing was not great.
Alterations of the enamel after topical application of bleaching
agents, presenting as major consequences are: ions release,
increased superficial roughness, stronger bacterial attachment
and hardness alteration.The aims of the study were to evalu
ate
the effect of the bleaching agent (35%hydrogen peroxide) for
vital teeth by using light source on the release of ions from the
enamel surface. our sample consisted of 30 sound enamel
surface for control group,30 sound enamel surface
for(35%hydrogen peroxide), and then application of light
radiation to activate the bleaching agent. Ion Chromatography
were used to measure the ions release .
This research is based on the use of different types of mineral
mordants, mineral salts, in the dyeing process using the aqueous
extract of eucalyptus leaves. The used mordants are aluminum
potassium sulphate, copper sulphate, iron sulphate and mi
xtures of
these mordants. Study the effect of these mordants on the dyeing
process.
This study was conducted at AL Assad University Hospital in Latakia in 2012. It was a prospective study of pregnant patients admitted Department of Obstetrics and Gynecology during the period between 1\9\2012 and 1\9\2013. These patients had regular
menstrual information and were in 37th week or more of gestation and did not have any disease in the mother or fetus affecting the growth of the fetus.
The study included 122 patients regardless of the mode of delivery. Each patient's information was documented: estimated gestational age by LMP (last menstrual period) and estimated gestational age by ECHO using (BPD : biparietal diameter, FL: femur length) during the 24-hour from delivery, presentation and amount of liquid by ECHO. Gestational age ranged between 37 and 41.5 weeks "with an average of 38.6 weeks" and a standard deviation of 1.1 weeks" by LMP.
Results showed almost convergent values based on all BPD and FL. There was also a stronger correlation between the ages of pregnancy estimated FL, LMP than BPD, LMP. Moreover, there was presence of a strong correlation between the ages of pregnancy estimated using BPD, FL and LMP when the presentation was breech. It was also observed that the presence of a good amount of liquid is necessary to estimate the age pregnancy ultrasound.
