Developing a Model for Controlling Internal Corrosion in Water Supply System  [PDF]
Byung-Gi Hwang
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.92013
Abstract: A model was developed to generate charts that fit the conditions as diverse temperatures and ionic strengths, and that estimate the diversified state of water. The chart can be used as a tool for controlling corrosive waters resulted in internal corrosion and the model producing charts composed of a number of sub modules, and each module incorporated parameters including acidity, alkalinity, pH, and calcium ion. Utilizing the chart water quality of the raw water in G water purification works was estimated to be unsaturated and Langelier index becomes -1.4 which means that the water is highly corrosive and calcium carbonate would not be precipitated. Thus, the water requires treatment as the injection of water stabilizing chemicals to promote an oversaturated (protective) condition. As a result of adding 5 mg/L of lime, it is possible to be precipitated with 5 mg/L, and the water becomes noncorrosive. In addition, when 5 mg/L of caustic soda is added as a conditioning chemical, it signifies to be precipitated with 9 mg/L, and the water also turns out to be largely noncorrosive. Both chemicals are possible to use for the water to be favorable for the formation of a protective film. Optimum injection rate for controlling corrosion can be found by repeating the procedures until the well-conditioned water criteria are satisfied.
Radiation dose in paediatric computed tomography: risks and benefits
GI Ogbole
Annals of Ibadan Postgraduate Medicine , 2010,
Abstract: Computed tomography (CT) is a powerful tool for the accurate and effective diagnosis and treatment of a variety of conditions because it allows high-resolution three-dimensional images to be acquired very quickly. However as the number of CT procedures performed globally have continued to increase; with growing concerns about patient protection. Currently, no system is in place to track patient doses and the lifetime cumulative dose from medical sources. The widespread use of CT even in developing countries has raised questions regarding the possible threat to public health especially in children. The best available risk estimates suggest that paediatric CT will result in significantly increased lifetime radiation risk over adult CT. Studies have shown that lower milliampere-second (mAs) settings can be used for children without significant loss of information. Although the risk–benefit balance is still strongly tilted toward benefit, there is still need for caution. Furthermore since the frequency of paediatric CT examinations is rapidly increasing, and estimates suggest that quantitative lifetime radiation risks for children are not negligible, efforts should be made toward more active reduction of CT exposure settings in paediatric patients. This article hopes to address this concerns and draw attention to the fact that children are not ‘small adults ’ and should therefore be treated differently.
Case Report: Posterior Urethral Valves with Severe Unilateral Vesicoureteral Reflux in a 3-year–old Boy
GI Ogbole
Annals of Ibadan Postgraduate Medicine , 2007,
Abstract: In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function. Others are urinary ascites or urinoma in newborns and large congenital bladder diverticula. These conditions most likely provide a pop-off mechanism preventing the development of high intravesical pressure. Only 5% of patients with PUV and an associated popoff mechanism will develop renal failure as opposed to40 % of patients with PUV without a protective factor. We present a 3-year-old boy with posterior urethral valves and a severe right unilateral vesicoureteral reflux. He had PUV ablation with Mohan’s valvotome and made satisfactory post operative recovery with indication on follow-up of preservation of renal function.
Oji: A Societal Bond from Cradle to Grave.

Abstract: Before the advent of the white-man, the Igbo people had held kolanuts in high esteem. The respect, honour and dignity accorded the kolanut had never been extended to any other nut or fruit. There was nothing one was doing without the kolanut. “Whether one was receiving a stranger, making a sacrifice, holding a ceremony or providing entertainment, kolanut must be vitally needed”. (Orji 1999). In the present Igbo Society, the presence of kolanut is nolonger well felt as people always replace it with other things like wine, garden eggs etc. If this should continue, the tradition accorded to kolanuts in Igbo land will fade away. This paper therefore, intended to give the concept of “Qj[,” its symbolism and its significance, in the Igbo world view. It went further to see “Qj[” as a thing or an instrument that holds the society together. This will help to widen the knowledge of the Igbo people on kolanut traditions and to boost the honour given to kolanut in Igbo land. It will also help the younger ones to understand the reason why Igbo people accord kolanut such honour. Related literally words were reviewed to widen the horizon of the research found in the analysis of the data collected, it was found out that: Igbo people especially youths no-longer accord respect and honour to kolanut. It was also discovered that western religion has taken over the real tradition of kolanut in Igbo land. Suggestions were made on the ways to restore the respect and honour given to kolanut in the past. In the end, summary and conclusion were drawn.
Metasedimentos siliciclásticos proterozoicos en la Sierra de Pie de Palo, San Juan: Procedencia y ambiente tectónico Proterozoic Siliciclastic metasediments in Sierra de Pie de Palo, San Juan: Provenance and tectonic setting

Revista de la Asociación Geológica Argentina , 2003,
Abstract: Los metasedimentos del Grupo Caucete aflorantes en la sierra de Pie de Palo constituyen una pieza importante para entender la evolución del margen gondwánico durante el Proterozoico tardío a Paleozoico temprano. Esta secuencia metamórfica está en contacto tectónico, a través del Corrimiento Las Pirquitas, con el Complejo Pie de Palo (Mesoproterozoico). El Grupo Caucete está integrado por dos unidades mayores, una siliciclástica y otra carbonática, y basado en estudios de campo entre las quebradas Las Pirquitas y La Petaca y posterior laboratorio, ha sido dividido en cuatro formaciones. La parte siliciclástica incluye a la Cuarcita El Quemado, la que está intercalada con la Formación La Paz, unidad de carácter volcaniclástico. Los carbonatos están representados por la Formación El Desecho (areniscas y limolitas carbonáticas con mármoles dolomíticos) y la Caliza Angacos. Los primeros resultados geoquímicos fueron utilizados para comparar la Cuarcita El Quemado y la Formación La Paz con las metagrauvacas del Complejo Pie de Palo. Su composición mineralógica ha determinado el comportamiento geoquímico de los elementos mayoritarios, mientras que las tierras raras y elementos traza, al estar concentrados principalmente en los minerales pesados, muestran que los procesos sedimentarios han jugado un rol importante en su distribución. Los sedimentos siliciclásticos se habrían originado por la destrucción de rocas corticales procedentes de áreas orogénicas, con un importante componente félsico asociado con rocas ígneas originadas en arcos magmáticos más o menos evolucionados. Los mismos se habrían depositado en una plataforma continental durante el Proterozoico superior (670 Ma, U/Pb en circones detríticos). Metasedimentary rocks of the Caucete Group outcropping at the western slope of Sierra de Pie de Palo are an important key to understand the geological evolution of the western margin of Gondwana during late Proterozoic - early Paleozoic times. This metamorphic sequence is in tectonic contact with the mesoproterozoic-age Pie de Palo Complex through Las Pirquitas Fault. The Caucete Group is composed by two major units, one of siliciclastic nature and the other of carbonates. Between Las Pirquitas y La Petaca valleys this group has been divided in four different units based on detailed field work laboratoy studies. The siliciclastic part of the sequence included the El Quemado Quartzite which is interlayered with La Paz Formation, a volcaniclastic unit. The carbonate sequence is composed by El Desecho Formation (carbonate sandstones and siltstones with dolomite
Estimation of mineral and trace element intake in vegans living in Japan by chemical analysis of duplicate diets  [PDF]
Munehiro Yoshida, Noriko ?gi, Yuki Iwashita
Health (Health) , 2011, DOI: 10.4236/health.2011.311113
Abstract: Thirty-six daily duplicate diet samples were collected from 12 healthy female Japanese vegans and sodium, potassium, calcium, magnesium, phosphorus, iron, zinc, copper, manganese, iodine, selenium, chromium and molybdenum in the diets were measured to estimate mineral and trace element intake by Japanese vegans. Significantly higher intake of potassium, magnesium, phosphorus, iron, copper, manganese and molybdenum was observed in vegans than in general Japanese women, but no difference was observed in sodium, iodine, selenium and chromium intake. Vegan calcium intake tended to be low compared to that of general women but the difference was not significant. Since high potassium, magnesium and iron intakes cannot be achieved by general Japanese diets and high intake of potassium and magnesium may prevent hyperextension and cardiovascular disease in vegans, there are few problems with Japanese vegan diets regarding mineral and trace element intake, except for calcium intake, which is low as it is in the general Japanese people.
O estatuto temporal e social do signo
Bortolotti, Ricardo Gi?o;
Trans/Form/A??o , 1999, DOI: 10.1590/S0101-31731999000100013
Abstract: this paper has as its objective to show how the knowledge process occurs in a triadic structure whose characteristics cannot prescind either of temporality or its social aspect. would it not be so in accordance with the subjacent dualism in the traditionals of theories, the scope of knowledge would be itself limited by the inevitability the appeal to a thing-in-itself.
Childhood Risk Estimation of Lead Metal Poisoining from Edible Land Snail at Abandoned Battery Factory Environment
IE Ebenso, GI Ebenso
Ethiopian Journal of Environmental Studies and Management , 2011,
Abstract: The childhood lead (Pb) poisoning risk from consumption and risk model data of snail meat from Pb metal contaminated sites of entrance (control), storage dump, dried effluent and waste dump at an abandoned battery factory, in Niger Delta, Nigeria were estimated. Results implicated snail meat from waste dump site with hazard quotient of 2.40 and childhood exposure of 0.12mg/kg/day Pb associated with non carcinogenic adverse effects on health. Control site was risk free. Childhood exposure and snail meat Pb accumulation was dependent on Pb concentration being significantly higher at non-control sites. This study should fast track industrial environmental audits of existing (including abandoned) industrial projects and epidemiological studies in communities around contaminated/polluted sites.

SI Efanga, GI Usen
African Research Review , 2010,
Abstract: The purpose of this study was to explore the leadership frames of supervisor of public schools in Nigeria required for effective implementation of Universal Basic Education (UBE) in Nigeria. This study draws on work of Bolman and Deals (1990) four-Frame Leadership Model. Using Three research questions and three null hypotheses, the samples of the study consisted of 600 supervisors of public schools in Nigeria. Data collection was done through a five-point Likert scale questionnaire, its internal coefficient of internal consistency was 0.85 using Cronbach alpha. The data obtained were statistically analysed using mean scores and independent t-test analysis. Result indicated that distributed leadership is essential ingredient for promoting educational excellence. It was concluded that distributed forms of leadership among the wider staff is likely to have a significant influence on the academic achievement of students/pupil outcomes than that which is likely top down. It was recommended among others that the type of leaders demanded for effective implementation of UBE are not leaders involved in money running at billion of naira in foreign bank account to the detriment of welfare of their people. That it should be an engagement of many people in leadership activity of directing and following the contour of expertise in an organization.
