The study was conducted in a peri-urban village named, Panchpy under Gafargaon upazila of Mymensingh district with stinging catfish (Heteropneustes fossilis ) and carps ponds to produce aquaponics vegetable kolmi (water spinach, Ipomoea aquatica ) towards using waste substances of intensive stinging catfish ponds. Aquaponic plant (water spinach, Ipomoea aquatica ) was grown in floating trays in the selected ponds. The water quality parameters including, temperature, pH, dissolved oxygen, nitrite and ammonia were measured during study period.The level of ammonia was higher in catfish pond compared to carps pond water. Inversely, the dissolved oxygen content of catfish pond water was lower than that of carps pond. In the stinging catfish pond, the mean value (± SE) of plant length, weight, number of branches and leaves were recorded at 27.67 ± 1.76, 62.67 ± 2.03, 13.00 ± 1.15 and 55.33 ± 3.18, respectively. The corresponding values 19.33 ± 1.45, 46.67 ± 1.86, 9.33 ± 1.45 and 43.00 ± 2.88, respectively in carps pond, were significantly lower than that of catfish pond. Overall the percent weight gain of kolmi was higher in catfish pond. A positive correlation was found between the length and weight of kolmi produced in both catfish and carp ponds, however R2 value of that relationship was higher for catfish pond due to higher level of available waste nutrients in water. This indicates that the potential of aquaponics research and development in intensively feed catfish aquaculture ponds at the farmer level that can feed the growing population in both rural and urban areas of Bangladesh.Res.

Tigris River in Baghdad city that penetrate the rural and urban areas is polluted by many organic substances from different user activities including industrial, agricultural, and domestic purposes. Therefore to monitor and protect the river water from pollution, a remote monitoring system for Tigris river water in Baghdad is suggested. Different water quality parameters; Dissolved oxygen (DO), Electrical conductivity (EC), Total Dissolved Solids (TDS), and PH are measured from two areas near the Tigris River; oil refinery and power station. It show that wastes from these stations are polluted the river with their industrial wastes.

AbstractAcute haemorrhagic conjunctivitis (AHC) outbreaks are reported frequently in China. However, the transmissibility of AHC remains unclear. This study aimed to calculate the transmissibility of the disease with and without interventions. An AHC outbreak dataset from January 2007 to December 2016 in different schools was built in Hunan Province. A Susceptible-Infectious-Recovered (SIR) model was adopted to calculate the effective reproduction number (Reff) of AHC. Reff was divided into two parts (Runc and Rcon) where Runc and Rcon represent the uncontrolled and controlled Reff , respectively. Based on Runc and Rcon, an index of effectiveness of countermeasures (Ieff) was developed to assess the effectiveness of countermeasures in each outbreak. During the study period, 34 AHC outbreaks were reported in 20 counties of 9 cities in Hunan Province, with a mean total attack rate of 7.04% (95% CI: 4.97–9.11%). The mean Runc of AHC outbreaks was 8.28 (95% CI: 6.46–10.11). No significance of Runc was observed between rural and urban areas (t = −1.296, P = 0.205), among college, secondary, and primary schools (F = 0.890, P = 0.459), different levels of school population (F = 0.738, P = 0.538), and different number of index cases (F = 1.749, P = 0.180). The most commonly implemented countermeasures were case isolation, treatment, and health education, followed by environment disinfection, symptom surveillance, and school closure. Social distance, prophylaxis, and stopping eye exercises temporary were implemented occasionally. The mean value of Rcon was 0.16 (range: 0.00–1.50). The mean value of Ieff was 97.16% (range: 71.44–100.00%). The transmissibility of AHC is high in small-scale outbreaks in China. Case isolation, treatment, and health education are the common countermeasures for controlling the disease.

No Semiárido Alagoano os estudos sobre os parâmetros de qualidade de água ainda são pouco documentados e, em alguns casos, escassos, quando comparado à região costeira do estado, desta forma, análises esporádicas nesses corpos d’água tornam-se imprescindíveis. Objetivou-se no presente artigo analisar os parâmetros físico-químicos de qualidade de água em sete nascentes localizadas nas áreas rural e urbana do município de Olho D’Água do Casado, Semiárido Alagoano. Foram coletados dados in situ de pH, temperatura, sólidos totais e condutividade elétrica com auxílio de um sensor óptico. À exceção do parâmetro temperatura, constatou-se que a maioria das nascentes analisadas, nas duas áreas, apresentaram padrões de qualidade de água que extrapolam as diretrizes da Resolução CONAMA/2005. Comparativamente, as nascentes da área urbana apresentaram maior dinâmica e maiores níveis discrepantes nos parâmetros analisados. Faz-se necessário a elaboração de um quadro com medidas mitigadoras que abranjam tanto a esfera socioeconômica quanto a ambiental, visando dar a estes mananciais uma melhor proficiência para a população residente em seu entorno, tanto para fins de abastecimento quanto para criação e agricultura, e concomitantemente buscando o equilíbrio entre sua utilização e a reparação e preservação da dinâmica natural. É pertinente afirmar que o banco de dados obtido tem elevada relevância social, científica e ambiental no que concerne à qualidade de água no Semiárido Alagoano, servindo de base para o uso e manutenção consciente das nascentes estudadas e como subsídios para futuros trabalhos. Water Quality Parameters in Springs in the Municipality of Olho D'Água do Casado, Alagoas Semiarid A B S T R A C TIn the Alagoas Semiarid, studies about the parameters of water quality are still poorly documented and, in some cases, scarce when compared to the coastal region of the state, so sporadic analyzes in these bodies of water become essential. The aim of this study was to analyze the physical and chemical parameters of water quality in seven nascent located in the rural and urban areas of the municipality of Olho D'Água do Casado, Alagoas Semiarid. In situ data of pH, temperature, total solids and electrical conductivity were collected with the aid of an optical sensor. With the exception of the temperature parameter, it was verified that most of the nascents analyzed in both areas presented water quality standards that exceed the CONAMA/2005 Resolution guidelines. Comparatively, the nascents of the urban area presented greater dynamics and higher levels of discrepancy in the analyzed parameters. It is necessary to create a cadre with mitigating measures that cover both the socioeconomic and environmental spheres, aiming to give these sources a better proficiency for the population residing in their surroundings, both for sourcing purposes and for breeding and agriculture, and concomitantly seeking the balance between its use and the repair and preservation of the natural dynamics. It is pertinent to affirm that the database obtained has high social, scientific and environmental relevance regarding water quality in the Alagoas Semiarid, serving as a basis for the conscious use and maintenance of the nascents studied and as subsidies for future works.Keywords: Spring, Semiarid, chemical-physical analysis.

Intellectual Level

This paper aims to reflect an effort to identify the problems associated with the educational learning process, as well as its function to express some inherent considerations to the most effective forms of the classroom management. Mentioned in this discussion are ways of management for various categories of students, not only from an intellectual level, but also by their behavior. Also, in the elaboration of this theme I was considering that in addition to other development directions of the country, an important place is occupied by the education of the younger generation in our school environments and especially in adopting the methods of teaching and learning management with a view to enable this generation to be competitive in the European labor market. This, of course, can be achieved by giving this generation the best values of behavior, cultural level, professional level and ethics one of an European family which we belong to, not just geographically. On such foundations, we have tried to develop this study, always improving the reality of the prolonged transition in the field of children’s education. Likewise, we have considered the factors that have left their mark on the structure, cultural level and general education level of children, such as high demographic turnover associated with migration from rural and urban areas, in the capacity of our educational institutions to cope with new situations etc. In the conclusions of this study is shown that there is required a substantial reform even in the pro-university educational system to ensure a significant improvement in the behavior of children, relations between them and the sound quality of their preparation. Used literature for this purpose has not been lacking, due to the fact that such problems are usually treated by different scholars. Likewise, we found it appropriate to use the ideas and issues discussed by the foreign literature that deals directly with classroom management problems. All the following treatise is intended to reflect the way of an effective classroom management.

This review of the Literacy and Education Bklletin1 of the 1961 Census is fourth in the series of review articles published in this journal2. The Bulletin under review forms a part of the interim report on the characteristics of the population of Pakistan. It gives information on the number of illiterate and literate persons by age and sex for rural and urban areas on division and district basis; illiterate and literate.population in selected cities and towns; and the educational levels attained by the literate population by age and sex for divisions and districts. Relevant statistical notes and statements precede the tables in the Bulletin. The objective of this review is to describe the meaningfulness and significance of literacy statistics. To this end, a distinction is made between formal and functional levels of literacy. Comparisons of the 1951 and 1961 census figures are undertaken to indicate the progress of literacy and education during the past decade with reference to the effect of intercensal rate of population growth on such progress. Certain questions regarding the reliability of data are raised, which emphasize the need for caution in the interpretation of literacy statistics.
