public bathes have much importance in islamic cities, after the most significant structures like mosques and schools. there are a number of factors affecting the construction of bathes among which temperature regulation, humidity, access path, location in the urban texture, watercourses, and construction of exit paths are the most important. this study tries to make a comparative analysis of t...

Ethyl esters of omega-3 fatty acids are active pharmaceutical ingredients used for the reduction in triglycerides treatment hyperlipidemia. Herein, an ultrasonic packed-bed bioreactor was developed continuous production docosahexaenoic acid (DHA) and eicosapentaenoic (EPA) ethyl from DHA+EPA concentrate acetate (EA) using immobilized lipase, Novozym® 435, as a biocatalyst. A three-level–two-fac...

Brazil has a great variety of fruits which are rich in bioactive compounds, such as the genipap fruit. Both peel and pulp have beneficial components for health, making study this fruit important proper use its functionalities. The objective work was extraction compounds from by different techniques. Extraction processes were carried out using devices (orbital incubator shaker, ultrasonic bath, ...

The texture coefficients of the (111) and (200) planes of deposited films of copper were strongly affected by ultrasonic agitation. In general, the texture coefficient of the (111) plane grew without ultrasonic agitation, but that of the (ZOO) plane increased greatly with it. Limiting current densities and cathodic current efficiencies both increased, while grain size was reduced. The stoichiom...

An ultrasonic dental descaling instrument has been characterised using sonochemical techniques. Mapping the emission from luminol solution revealed the distribution of cavitation produced in water around the tips. Hydroxyl radical production rates arising from water sonolysis were measured using terephthalate dosimetry and found to be in the range of mol min -1 , comparable with those from a s...

Ankyropetalum extracts were obtained by using two different extractors (Soxhlet and ultrasonic bath). The phenol, flavonoid, DPPH, FRAP, antimicrobial activity properties of the investigated. In addition, fatty acid composition was determined in GC-MS. High values found A. reuteri gypsophiloides for total phenolic flavonoid contents, respectively. DPPH FRAP high arsusianum gypsophiloides, Bette...

The aim of this study is to determine acetic acid, ascorbic citric oxalic acid and tartaric in Sudanese medicinal plants (Adansonia digitata fruit pulp, Hibiscus sabdriffa calyx, Hyphaene thebaica pulp Tamarindus indica pulp) by RP-HPLC-UV method. method used based on using an ultrasonic bath for extracting organic acids. investigation showed that concentrations (1.65 mg/g ±0.099), (56.00 ±0.22...

The presented research addresses the problem of dependency analysis ultrasonic signal measured by a sensor in an engine oil bath. is performed on selected solution containing its own generator and receiver detecting level which it immersed. influence resulting amplitude received mainly due to temperature, as shown regression ANOVA (Analysis Variance) testing performed. analyzed dependence time ...
