Abstract
BACKGROUND: Psoriasis is a chronic, inflammatory and multifactorial dermatosis that impairs quality of life (QoL). Health-related QoL has become an important element in medical decision making along with the effectiveness and the harmlessness of the treatments.OBJECTIVE: To assess the impact of psoriasis in the QoL of patients with psoriasis by using the DLQI scales.METHODS: A cross-sectional study, during ten months, was conducted in the Department of Dermatology of the University Hospital Joseph Raseta Befelatanana Antananarivo Madagascar including patients more than 15 years-old with moderate to severe psoriasis. The severity of psoriasis was assessed using the “Psoriasis Area and Severity Index (PASI)”. QoL of patients with psoriasis was evaluated by using the DLQI scales.RESULTS: 80 patients were included, their mean age was 36.52 years and the male to female was 1.5:1. The mean DLQI score was 13.85. Symptoms, feelings and psychic were the most altered dimensions. QoL was impaired in young patients, single, having medium level education. Even though patients with disease duration more than 5 years had higher DLQI score than other patients, the difference was not statistically significant (p=0.36). Furthermore, clinical presentation of psoriasis didn’t influence patient’s QoL (p=0.73). Patients with nail involvement had QoL impaired but the difference with another localization was not statistically significant (p=0.2).The quality of life was influenced by body area involved. The higher the body surface area involved, the more QoL is impaired (p=0.002). Furthermore, the higher the PASI, the more QoL is altered (p=0.002).CONCLUSION: Psoriasis has a negative impact in the quality of life in Malagasy patients with psoriasis, especially in younger and single patients. Worse quality of life is correlated to severity of psoriasis.

Abstract
Background The purpose of the study was to investigate to understand the situation of sleep quality and anxiety among nurses in tertiary hospitals in China, and analyze their influencing factors. Methods A cross-sectional survey was performed for nurses in Beijing tertiary hospitals including Beijing Tongren hospital, Beijing Anzhen Hospital and Beijing Children Hospital. The Pittsburgh Sleep Quality Indes (PSQI) and Zung Self-Rating Anxiety Scale (SAS) were used to measured the sleep quality and anxiety symptoms, respectively. Survey of quality of life in nurses was measured by 36-item Short Form Health Survey (SF-36). Spearman’s correlations analysis and logistic regression analysis was used to understand the influencing factors with sleep disorder, anxiety symptoms and quality of sleep. Quality of life (both PCS and MCS) were affected by influencing factors including marital status, working years, education background, income monthly, working hours, regular diet, physical exercise, sleep disorder, anxiety symptoms, felling of stress, and stress from economic, social, occupational. Results 643 registered nurses in three tertiary hospitals were surveyed, 517 (80.4%) returned questionnaires were valid for analysis. The average PSQI score was 7.71±3.62, including 372 participants that scores were above 5 (72.0%). The average SAS score was 45.18±9.90,including 157 participants with a SAS score > 50 (30.4%) that had different anxiety symptoms. The nurses’ sleep quality were affected by some factors including income monthly, working hours, regular diet, physical exercise, stress from economic, social, occupational. Education background, income monthly, working hours, regular diet and economic stress, social stress, occupational stress have significantly related to anxiety symptoms. Correlation between sleep disorder and anxiety severity was positive for nurses. Conclusions The situation of sleep disorder and anxiety symptoms among nurses in tertiary hospitals in China were very serious. The problem has negative effect on physical and mental health in nurses which remind hospital administrators should take preventive actions. In addition, the results of the study hinted that promotion of health lifestyle, effort-reward balance and providing social support may be significant to decrease the poor sleep quality and anxiety symptoms and increase quality of life in nurses.

Abstract
A cross-sectional study was conducted to determine prevalence and risk factors of ruminal disorders with identification of pathophysiological changes of rumen fluid and blood in sheep from January to June, 2019 in and around Gondar town, Northwest Ethiopia. One hundred seventy two sheep were selected by systematic random sampling technique and 21 apparently healthy sheep were selected by purposive sampling technique. Complete case history and clinical signs were recorded. Samples (rumen fluid and blood) were collected and analysed in the laboratory. The data was analysed using SPSS version 20. The prevalence of ruminal disorders in sheep was 55.2% and identified major types of ruminal disorders were simple indigestion (25.6%), ruminal acidosis (20.35%), ruminal tympany (5%) and ruminal alkalosis (4.1%). The most prominent clinical signs recorded in sheep with ruminal disorders were anorexia and inappetence followed by diarrhoea, dullness, dehydration, bloat and abdominal pain. Ruminal motility and protozoal motility were significantly (p<0.05) reduced where as percentage of PCV was significantly increased (p<0.05) in sheep’s with ruminal disorders. Sedimentation activity time was significantly reduced in sheep with ruminal acidosis however, it was significantly (p<0.05) increased in ruminal alkalosis (p<0.05). Color, consistency and odour were affected during ruminal disorders. In multivariable logistic regression analysis showed that Male sex; (Adjusted Odds Ratio [AOR] = 6.044 ; 95% CI: 1.894-19.281 ), extensive farming system (AOR=6.358; 95% CI: 1.335-30.285), Crop residue and concentrate feed (AOR=23.01; 95% CI: 8.364-08.201), sudden change of feed (AOR=32.911, 95% CI: 7.959-136.092) and moldy feed (AOR=20.807, 95%CI: 6.245-69.325) were significantly (p<0.05) associated with occurrence of ruminal disorders in sheep.

Authors: Chen Jingmao , Zhang Dongyang , Hu Ping , Dong Shun , Zhang Xinghong 
Published: April 2020

Abstract
The high-performance and reliable ZrB2-SiC composites were fabricated by centrifugal gel casting and pressureless sintering. A well-dispersed ZrB2-SiC suspensions with up to 48 vol.% solid loading was achieved by adding 0.6 wt.% PAA dispersant and adjusting pH value to 11. The crack-free green ZrB2-SiC ceramic bodies with homogenous microstructure were prepared successfully by centrifugal gel casting with a relatively low monomer content of 3.5wt.% and centrifugal speed of 9000 r/min. After pressureless sintering at 2000 °C for 1 h, ZrB2-SiC composites with a relative density of 94.8%, a flexural strength of 394 ± 14 MPa and fracture toughness of 4.03 ± 0.10 MPa·m1/2 were achieved. This approach provided a promising colloidal processing to fabricate ceramic composites with reliable properties.

Este artigo constitui uma tentativa de fazer uma reflexão sobre o embate entre a supressão e a conservação da natureza na cidade, defendendo o fortalecimento da racionalidade ambiental como caminho ao resgate da beleza da paisagem urbana. No que concerne à metodologia, partiu-se da ontologia da realidade concreta, considerando suas diversas perspectivas de representação. Corroboramos, enfim, a hipótese de que é possível resgatar a beleza da paisagem através da implementação de um processo permanente de educação norteado pela racionalidade ambiental, o que se faz de fundamental relevância para a retomada do processo de desenvolvimento ambiental na cidade. Between the suppression and conservation of the nature in the city: the role of the environmental rationality towards the recovery of the beauty of landscape A B S T R A C T This article is an attempt to do a reflection of the clash between the suppression and conservation processes of the nature in the city, defending the role of environmental rationality as a way towards the recovery of the beauty of urban landscapes. With regard to the methodology, we took in account the ontology of concrete reality as a starting-point, considering at the same time different types of representation’s perspective. Finally, we confirm the hypothesis that it is possible recover the beauty of landscape through an educational process oriented by an environmental rationality, which is essential for the resumption of the environmental development process in the city.

Published: April 2020

Apresenta-se uma avaliação da maturidade do perfil geomorfológico da Bacia do Rio Parcatu, afluente do Rio São Francisco. As relações entre comprimento e queda média dos seguimentos de rios para cada ordem pelo método de Strahler são analizados por leis empíricas para comparação com um perfil teórico de máximo equilíbrio. Os resultados demonstram que a Bacia do Rio Paracatu está próxima de seu estágio máximo de maturidade, embora ainda não o tenha alcançado completamente. A partir do estudo aplicado, são tecidas reflexões sobre as possibilidades de investigação de bacias hidrográficas com base em abordagens de entropia, meta-estabilidade, geovulnerabilidade e evolução geomorfológica. A B S T R A C T An assessment of the maturity of the geomorphological profile of the Paracatu River Basin, a tributary of the São Francisco River, is presented. The relationship between length and average stream fall for each order using the Strahler method is analysed using empirical laws for a comparison to a theoretical profile of maximum equilibrium. The results show that the Paracatu River Basin is close to its maximum stage of maturity, though it has not achieved it completely. Based on this study, reflections are made about the possibilities to study this watershed based on entropy approaches, metastability, geological vulnerability and geomorphological evolution. Keywords: Equilibrium profile, entropy, metastability, geovulnerability, geomorphological evolution, Paracatu.

Authors: Monalisa Yani 
Published: April 2020

Penelitian ini bertujuan untuk menjelaskan mengenai holding period yang dapat memaksimalkan keuntungan skaligus meminimalkan resiko.Holding period yang digunakan bervariasi dari 5 hari kerja, 10 hari kerja dan 20 hari kerja, 100 hari kerja, 200 hari kerja sampai 300 hari kerja. Selain itu, penilian ini diharapkan dapat memberikan gambaran tentang kekeliruan dari time diversification.Dari hasil penelitian, dengan menggunakan historical data berupa harga penutupan saham periode Januari 2012 - Desember 2017, holding period makin panjang akan menghasilkan CV makin rendah. Sedangkan time diversification menurut Bodie, Kane dan Marcus terbukti benar, bahwa dalam jangka panjang, resiko akan bertambah namun tingkat pengembalian (return) akan menjadi tidak pasti. Ini terbukti dengan makin lebarnya perbedaan antara kisaran harga teoritikal dengan kisaran harga aktual, seiring dengan makin lamanya holding period.
