This work investigates the root causes of the incidence of solder flux residue underneath electronic components in the manufacture of power modules. The existing deionized water-based centrifugal cleaning process was analyzed and hypotheses for root causes of the problem were proposed. The experimentation included cleaning tests using agitation and soak cycles. Parameters such as chemical agent...

High throughput screening technologies such as acoustic droplet ejection (ADE) greatly increase the rate at which X-ray diffraction data can be acquired from crystals. One promising high throughput screening application of ADE is to rapidly combine protein crystals with fragment libraries. In this approach, each fragment soaks into a protein crystal either directly on data collection media or o...

AIMS The aims of this study were to (i) assess the effect of low-cost hygiene and emollient regimens on the skin barrier function (SBF) of people aged >65 year with xerosis (dry skin) on their lower legs; (ii) to assess the utility of portable measures of skin barrier function in terms of stratum corneum hydration (SCH) and transepidermal water loss (TEWL) in community settings; and iii) to pro...

In this study, a series of experiments were conducted on testing facility and real-scale furnace, for analyzing the nitric oxide (NO) emission reduction. The effects temperature, oxygen concentration, amount secondary combustion air investigated in single-burner system. Additionally, NO-reduction rate before after modifications both burner furnace air-staged evaluated reheating furnace. air-to-...

Hypertension is a condition where the systolic blood pressure more than 120 mmHg, diastolic higher 80 mmHg. One of health problems that has frequently appeared throughout pregnancy and can develop complication hypertension in pregnancy. Based on Strait’s research (2012), prime factor causing deaths mothers their fetuses. be treated by pharmacology non-pharmacology therapy. therapies Epsom salt ...

wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. as the...

Soak feet with warm water is a combined therapy method of thermotherapy and hydrotherapy that works to release istamine bradykinin. The bradykinin causes vasodilation blood vessels. purpose the study: identify effect soaking on lowering pressure. Method:This research quantitative systematic review method. design used was Randomized Controlled Trials (RCT) 9 studies.Results:Obtained from studies...

Temporal binding of urea to lysozyme was examined using X-ray diffraction of single crystals of urea/lysozyme complexes prepared by soaking native lysozyme crystals in solutions containing 9 M urea. Four different soak times of 2, 4, 7 and 10 hours were used. The five crystal structures (including the native lysozyme), refined to 1.6 Å resolution, reveal that as the soaking time increased, more...
