The effects of particulate matter (represented by humic acid, kaolin and algae) on ultrafiltration membranes in micro-polluted water sources were investigated, and the mechanism of ultrafiltration membranes was further understood with the change of membrane flux and transmembrane pressure difference. The results showed that the removal rate of kaolin and algae by UF membrane was over 99%, while the removal rate of humic acid was only about 72%. Moreover, the extent of UF membrane fouling caused by humic acid was larger than that caused by kaolin and algae. The higher the concentration of humic acid, the more serious the membrane fouling was. Ultrafiltration membranes contaminated by humic acid were washed by 0.05mol/L NaOH alkali and 0.05mol/L HCL acid. The permeability of the membranes was restored to 91.24% of the cleaned surface, which was better than that of pure water, sodium hypochlorite and sodium hydroxide. It can provide better guidance for choosing appropriate cleaning agents for ultrafiltration membrane fouling.

In order to solve the problem of excessive Mn(II) content in water in some areas of China, TiO2 nanotubes and TiO2 powder are used to remove Mn(II). The experimental results show that both TiO2 nanotubes and TiO2 powder have certain manganese removal effect, and the effect of powder is better. When the pH was 5.6 and the 20W UV lamp was irradiated for 40 min, the removal rate of the powder was 64.3 %, and the removal rate of the nanotubes anodized for 1h was 35.3 %, and the removal rate of the nanotubes anodized for 30 min was 23.9 %. When the pH is adjusted to 7-8, the removal rate of the nanotubes is significantly improved. When the pH was 8, 20W UV lamp was irradiated for 40 min, the removal rate of nanotubes anodized for 1h was 60.4%.

Introduction: Non-Transmissible chronic diseases (NCDs) have been presented as a relevant health problem, due to the high number of premature deaths, quality of life deficits, with a high degree of limitation and disability, as well as being responsible for economic impacts on families, communities and public health services in general. Objective: To evaluate the impact of chronic noncommunicable diseases on the use of public health services. Method: Integrative review, data collected in electronic bases Lilacs, Medline / Pubmed, Sciello, where 830 articles were identified, and from the inclusion and exclusion criteria, 10 studies remained as final sample. The analyzed publications date from the period 2013 to 2017. For the research were used descriptors (Mesh / Decs) and free terms (Mesh Terms), crossed through the Boolean operator “AND”. Results: mortality studies indicate an increase in the proportion of deaths due to non-transmitted chronic diseases and also an increase in the proportion of hospitalizations, since the presence of chronic disease was associated with an increase of hospitalization in the last 12 months, 1.7 times. The use of health services in the last 12 months were, respectively, 3.4 times higher in the presence of four or more diseases. Hypertension had the highest prevalence among NCDs, with 21.4%, followed by depression (7.6%), arthritis (6.4%) and diabetes (6.2%). The degree of intense / very intense limitation presented higher prevalences for other mental illness (37.6%) and stroke (25.5%). A National Health Survey conducted in 2013 has revealed a rich and troubling panel of the country, with a high burden of NTCDs and disabilities, which should expand as a result of the aging population. There is strong evidence that correlates social determinants, such as education, occupation, income, gender and ethnicity, with the prevalence of CNCD. Conclusion: Indicators of health service utilization are important for assessing the quality…

Congenital variations of the aortic arch and great vessels are often encountered in clinical practice. This is a case report of a 60 year old lady diagnosed with carcinoma thyroid and during the procedure, incidentally diagnosed to have right common carotid artery crossing the trachea anteriorly. Post operative computed tomographic angiographic study confirmed the common carotid artery in the pretracheal position and aberrant right subclavian artery (ARSA) was discovered. This is a rare anamoly of the common carotid artery and to be kept in mind during the procedures done in the pretracheal position and other associated anomalies are to be evaluated.

Introduction: The psychologist in the professional trajectory builds different competences according to the national curricular guidelines. Psychology undergraduate courses when building their curricular matrices focus on knowledge and experience challenges in developing skills and attitudes for psychological performance. Art can be an ally in this learning scenario as a mediator to provoke the reflection about the other, about themselves, about social relations and the fields of professional practice. Objective: The present work reports one of the activities called Artepsi in a clinical hospital psychology stage, which is organized by the trainees themselves of the course of Psychology of college in Recife, Pernambuco, specialized in health. Methodology: Experience report. Results and discussion: Each meeting is planned by the trainees, decide themes, group dynamics, debates and make contact with speakers. The activities developed in the meetings seek to provoke reflections on the formation of the psychologist, challenges and professional dilemmas, refresher themes, integrating art and psychology. The Art element was expressed through discussions of films, origami, literature, music, reports of experiences, lectures trying to sensitize and affect the trainee to think about their own formation, caring for themselves and the other. Artepsi is an activity that allowed us to reflect on different themes, such as: depression, suicide, caring for oneself, mental health, psychoanalysis, art therapy, violence, among others. Conclusion: This proposal allowed us to reflect on a curricular internship activity that integrates art and psychology, allowing trainees to take on the role of protagonist in their training, developing decision-making skills, group work, exchange of experiences, strategic planning, mediation conflict and creativity. As well, it made possible to think about the future of its profession and a responsible and citizen action.

In the field of port and shipping, the mutual interest relationship between the port and the shipping company has always been a hot topic.On the one hand, the port needs the shipping company to park its port operations to obtain economic benefits and social benefits.On the other hand, shipping companies have their own considerations when facing different types of ports, and must consider them from the perspectives of maximizing their own interests and optimizing service levels.In this paper, the Stackelberg model and the Nash equilibrium model in game theory are used to analyze the basis of the choice of the interests of the port and shipping enterprises to establish a multi-influence factor and multi-targeted model of the profit distribution of the port and shipping enterprises.According to the research in this paper, the appropriate cooperation between the two parties can further enhance the efforts of the port and shipping companies, and realize the rational distribution of interests between the port and the shipping company, so as to achieve a win-win situation in the entire port supply chain.

Marginal fit of fixed dental prostheses is determined by the size of the gap between the margin of the restoration and finish line of the prepared tooth. The most important factors influencing marginal and internal fit of fixed dental prostheses are the material used, the type of finish line as well as peculiarities of various technique of restoration fabrication. The objective of the article is to review the literature about the marginal and internal fit of various fixed prosthetic constructions. A review of literature using Pubmed, Google Scholar, and Research Gate database was carried out and 73 articles mostly in English were selected. The keywords were “Computer-aided design, marginal gap, internal fit, marginal fit, and crown adaptation”. Clinically accepted boundary value of marginal gap is considered to be ≤100 μm. However, a number of factors such as milling machine, parameters of bur (diameter, sharpness), software, design preparation, smooth preparation margins and incorporation of rounded line angles on the tooth preparation, the type of finish line, material and fabrication method of the construction and type of impression method should be taken into consideration in order to achieve these results. The perfect marginal and internal fit are the guarantee of construction success and longevity. As a sizeable marginal opening concedes more plaque accumulation, gingival sulcular fluid flow and bone loss, following in microleakage, recurrent caries, periodontal disease and a decrease in the longevity of the prosthetics restorations. Currently used techniques of restoration manufacturing, including constructions manufactured by computer aided design/computer aided manufacturing system can provide clinically allowable marginal fit.

With the increasing energy crisis, the development and utilization of wind energy, which is a substitute for traditional energy sources and has renewable and cleanliness, has gradually attracted the attention of people all over the world. While the wind power industry is growing rapidly and the unit capacity of the unit is gradually increasing, the operational safety of wind power equipment is receiving more and more attention. If the wind turbine component fails, the small one will result in downtime maintenance, and the other will cause the machine to be destroyed. Because the wind farm is built in remote areas or offshore areas far away from the city, the traffic is inconvenient, and the wind turbines are at high altitude, so it is very difficult to maintain the unit. Once a fault or fire occurs, it is difficult to rescue in time. Let it develop its accident. In view of the high cost of detection, the failure of detecting faults, and the high proportion of missed faults, the on-line monitoring of the operating status of wind power equipment, the real-time diagnosis of early warning faults, and the maintenance of equipment are also important. The online monitoring system is applied to the health monitoring of wind power equipment, which not only can alert the equipment to potential failures, avoid the occurrence of major accidents, but also can determine the fault type and severity of the equipment based on the integration of existing analytical methods. Save on operational maintenance and repair costs. At a deeper level, mining and analyzing the monitoring data can also complete the estimation of the equipment’s continuous running time before the major accident, promptly remind the staff and provide reasonable rescue plans and solutions.

The treatment consisted of different doses of Paclobutrazol (PP333) namely 1.0g and 0.5g/canopy diameter along with control. Paclobutrazol was applied once in a year 15 October 1997 and 15 September 1998 in soil around the tree canopy spread. Paclobutrazol did not affect on Sugar, pH, Colour, K or glucose-fructose ratio, reduced sugar concentration and did not effect TSS and Firmness of Apple, increased TSS, Ascorbic Acid, Chlorophyll, ß-carotene, amylase, peroxides activity for 12 days in Dashehari Mango in storage at ambient temperature (30-33°C), chemical used Paclobutrazol [(2RS, 3RS)-1-1(4-Chlorophenyl)-4, 4-dimethyl-2-(1,2,4-trizol)-1-yl)] Pentan-3-ethanol.

The compound Paclobutrazol [(2RS, 3RS)-1-(4-chlorophenyl)-4, 4-dimethyle-2- (1, 2, 4 Triazol-1-y)] pentan-3-ethanol was the action of this retardants can be antagonized by Gibberellins (GA3) and ent-Kaurenoic acid. The growth regulating properties of paclobutrazol are mediated by changes in the levels of important plant hormones including the gibberellins (GAs), abscisic acid (ABA) and cytokinins (CK). Paclobutrazol (PBZ) affects the isoprenoid pathway, and alters the levels of plant hormones by inhibiting gibberellin synthesis and increasing cytokinins level. When gibberellins synthesis is inhibited, more precursors in the terpenoid pathway accumulate and that resulted to the production of abscisic acid. PBZ has been used to provide plant protection against numerous abiotic stresses such as chilling, water deficit stress, flooding and salinity. Paclobutrazol acts as stress protectant by maintaining relative water content, membrane stability index, photosynthetic activity, and photosynthetic pigments and protects the photosynthetic machinery by enhancing the level of osmolytes, antioxidant activities and level of endogenous hormones and thereby enhances the yield. It is suggested that its main biochemical action is to block the reactions that lead from ent-Kaurene to ent-Kaurenoic acid in the course of Gibberellins biosynthesis courses, reduced vegetative growth more intensively than root growth by this compound.
