The New Infinite Sequence complexion Solutions of a Kind of Nonlinear Evolutionary Equations

Journal of Applied Mathematics and Physics 2015年第12期3卷 1624-1632页

作者： Lina Yi Jundong Bao Taogetusang College of Mathematical Science Inner Mongolia Normal University Inner Mongolia China

The method combining the function transformation with the auxiliary equation is presented and the new infinite sequence complexion solutions of a class of nonlinear evolutionary equations are constructed. Step one, according to two function transformations, a class of nonlinear evolutionary equations is changed into two kinds of ordinary differential equations. Step two, using the first integral of the ordinary differential equations, two first order nonlinear ordinary differential equations are obtained. Step three, using function transformation, two first order nonlinear ordinary differential equations are changed to the ordinary differential equation that could be integrated. Step four, the new solutions, B?cklund transformation and the nonlinear superposition formula of solutions of the ordinary differential equation that could be integrated are applied to construct the new infinite sequence complexion solutions of a class of nonlinear evolutionary equations. These solutions are consisting of two-soliton solutions, two-period solutions and solutions composed of soliton solutions and period solutions.

This paper presents the development of a new remediation technology for contaminated sandy soil using humic acid (HA). Distribution of amount of Cr (VI) in the aqueous or solid system containing humic acid and sandy soil, was studied using batch experiments, es-pecially for effects of reaction time, pH, concentrations, temperature and irradiation on the reduction of Cr (VI), and the optimum reaction conditions. The results indicated a significant increase of the adsorption of Cr (VI) because of the complexion reaction between HA and Cr (VI) that occurred under acidic condition. The reaction mechanisms of HA with chromium on sand surfaces were certified. Thus it came to a conclusion that HA could be used effectively on remediation of Cr (VI)–contaminated soil and groundwater in a wide range of pH, with or without sunlight. These results suggest that the organic-inorganic complex—such as sandy soils coated with humic substances—is important as a metal reservoir in the environment.

Effects of Mild Hyperthermia Treatment Using Nano-Mist Sauna on Blood Gas Parameters and Skin Appearance

Physicians often observe patients’ complexion (their natural skin color) as an indicator of health. The complexion may depend on the internal environment, however, very few researchers studied its evidence. We previously reported various benefits of a mild hyperthermia treatment on human health using the nano-mist sauna (NMS), including acceleration of gas exchange (O2 and CO2) in the venous blood, enhancement of immunity, and the modulation of autonomic nervous system. However, the effects of NMS on skin appearance are unknown. There is a historical and widespread belief that mild hyperthermic treatments such as hot springs are good for improving skin appearance. However, the effect of NMS on the skin appearance has not been examined. In the present study, we examined the color of venous blood using the CIELAB (a color space specified by the French Commission internationale de l’éclairage) method, and then compared the color changes before and after NMS stimulation. Next, we examined correlations of blood gas parameters with color elements of the venous blood, which are highly dependent on oxygen. Our results suggest that the colors and appearance of the face depend on the internal environment, because there are numerous vessels under the skin. Thus, the color of the venous blood may provide medical evidence of changes in complexion. This new method may be useful for assessment of medical complexion by physicians, for use in determining internal health based on skin color information.

Treatment of Active Acne Vulgaris by Chemical Peeling Using TCA 35%

Background: The pathogenesis of acne vulgaris is multifactorial, and therapy can be directed at many of these factors, singly or in combination. There are different modalities of treatment of active acne vulgaris but they are often long lasting which could not be accepted by many patients. Objective: To evaluate the effectiveness, long term efficacy and safety of chemical peeling using 35% TCA solution in the treatment of active acne vulgaris. Patients and Methods:This clinical, interventional, therapeutic study was done at the Department of Dermatology—Baghdad Teaching Hospital during the period from January 2012 to March 2013. Eighteen patients with active acne vulgaris were included in this study, 10 (55.6%) females and 8 (44.4%) males. Their ages ranged from 15 to 35 (21.56 ± 5.501) years. Twelve patients were associated with acne scars. History and dermatological examination were performed for all patients regarding all demographic points related to the disease. Chemical peeling with 35% TCA used one session regarding active acne vulgaris and three sessions in patients with associated scarring. Scoring for active acne vulgaris and acne scar was done for each case before and after peeling to evaluate the severity of acne lesions and scarring. All patients were with Fitzpatrick’s skin types III and IV. Patients were followed up every two weeks for 12 weeks after starting therapy and every 4 weeks for 12 weeks after stopping the treatment to watch improvement, side effects and relapse. Results: Scoring for active acne vulgaris including papules and pustules showed highly statistically significant reduction after 2 weeks of therapy (p Conclusions: Chemical peeling by TCA 35% is a cost-effective mode of therapy for active acne vulgaris and acne scar with low down time in patients with dark complexion.
