Published: March 2018

Background: Ureteral stones are common problems in daily emergency department practice. Ureteric stone is responsible for 20%. Ureter obstruction caused by a ureteral stone triggers inflammatory changes in the proximal submucosal layer and prevents passage of the stone. C reactive protein (CRP) was found to be an indicator of ureteral stone outcome. The objective of this study was to measure serum CRP for patients with 4-8 mm distal ureteric stone and use its level as predictive factor for spontaneous stone passage.Methods: A prospective study was designed on a total of 73 patients (M=34; F=39) who were in the age group (18-50) years, who presented with ureteral colic secondary to a solitary unilateral, 4 to 8 mm distal ureteral stone. Patients were grouped according to spontaneous stone passage. The patients were selected at the urology unit, in Ghazi AL Hariri Hospital for Specialized Surgery, Medical City Complex in Baghdad from October 2014 till October 2016. The follow up continued until the stone spontaneously passed, as reported by the patient, or for a maximum period of 4 weeks.Results: Age, BMI, and gender did not show significant difference between the two groups ;30 have spontaneous stone passage (SSP), and 43 no spontaneous stone passage (no SSP). Stone size is significantly higher in the group without SSP their median is 6 mm compared to 4 mm for SSP group. CRP is significantly elevated in no SSP group compared to SSP. CRP, stone size and previous history of stone passage was the only significant and independent predictors of SSP (low CRP, low stone size, and positive history predict SSP). Conclusions: Stone size, CRP, previous Hx of stone passage are independent predictors for SSP. Measuring serum CRP levels is useful for predicting whether spontaneous ureteral stone passage will be successful. More aggressive treatment methods such as URS should be considered when serum CRP levels is high.
Curry’s Study on the Quality of Public Library Reference Service to LGBTQ Youth
Authors: Stevens Gregg A 
Published: March 2018

A Review of: Curry, A. (2005). If I ask, will they answer? Evaluating public library reference service to gay and lesbian youth. Reference & User Services Quarterly, 45(1), 65-75. Retrieved from https://www.jstor.org/journal/refuseserq
Abstract
Objective - To assess the quality of service provided by reference staff in public libraries when presented with a request for LGBTQ information by a young person.
Design - Unobtrusive observation without informed consent. Setting - Public library branches in the greater Vancouver area, British Columbia, Canada.
Subjects - Reference librarians.
Methods - A 19-year-old posing as a high school student approached reference desk staff at 20 public library branches. The student proxy, “Angela”, was instructed to ask for books on forming a gay-straight alliance at her school and, if there was a full reference interview, to also ask for recommendations of novels that the group might read. She recorded the reactions, both verbal and nonverbal, using Reference and User Services Association guidelines as a template. Library administrators were aware of the potential visits and permitted the research, but the reference desk staff were not aware of a potential visit by the student proxy. The researcher claimed that her method, while deceptive, was necessary to obtain authentic reactions from the library staff.
Main Results - Most reference librarians approached by Angela made adequate attempts to assist her, although a few library staff reacted negatively to her query. Half of the librarians reacted positively to the patron’s request, with most of the others providing neutral responses. Very few of the librarians actually taught the patron how to use the library’s catalog to search for materials, and most of the librarians were unable to find appropriate materials due to not knowing the appropriate search terms. Only three library staff showed overt disapproval of the search topic, such as frowning or rushing to finish the reference interview quickly, with most remaining objective or supportive. Because of the service she received, Angela stated that eight of the 20 libraries were welcoming enough that she thought she would return.
Conclusion - The wide range of responses received by Angela indicated that there was room for improvement in educating public library staff on gay and lesbian issues and materials, especially for gay and lesbian youth.

Published: March 2018

Mobile ad hoc networks are a dynamic and unpredictable community topology. There are numerous routing protocols that have been proposed for MANETs. Maximum pervious research centered on improving the present routing protocols or designing new routing algorithms. In our work, we investigated and compared the effect of mobility models on routing protocols for various site visitors instructions in MANETs. There have been many factors that affected the overall performance of routing protocols which include mobility and visitors styles. We designed several simulation models that added these factors together and measured the software performance in terms of end -to-end throughput (bit rate), latency, and jitter. three instructions of MANET routing algorithms (Proactive, Reactive, and Hybrid), mobility models (Random Waypoint and group), and three instructions of visitors styles (constant bit rate, variable bit rate, and random) have been used.
Narrativas de la legalidad en el hiperpresidencialismo constitucionalizado ecuatoriano = Narratives of legality in the Ecuadorian constitutionalized hyper-presidentialism
Authors: Guerrero Salgado Efrén Ernesto 
Published: March 2018

Resumen: La llegada al poder de Rafael Correa en el 2007 supuso diversos cambios en Ecuador, no sólo ideológicos sino también políticos, canalizados a través de una Asamblea Constituyente con el fin de ajustarse a los preceptos de la llamada “Revolución Ciudadana”. La nueva Carta Magna estableció un mayor número de controles sobre el Ejecutivo y creó nuevas funciones, como el Poder Electoral y de Transparencia y Control Social, que también girarían en torno a las decisiones del presidente de turno. Esto, combinado con la personalidad de Correa, generó un escenario de hiperpresidencialismo, amparado por elecciones populares que legitiman los cambios realizados por el Gobierno. En el caso ecuatoriano, lo que sucedió fue una disolución de la legalidad mediante la acción mediática, en el que la palabra del presidente no sólo fue regla de conducta, sino también una percepción de que la actividad pública no puede ser discutida, rebasando sus competencias constitucionalmente establecidas. El presente texto, busca explorar los mecanismos de existencia de un discurso decisionista en el periodo de gobierno 2013-2017 y sus consecuencias en la gobernabilidad democrática, para demostrar que la existencia de una autoridad que escape del poder del Estado sólo puede ser contenida por la norma y la fortaleza de las instituciones democráticas, capaces de mejorar la intensidad de la ciudadanía.Palabras clave: Hiperpresidencialismo, Rafael Correa, Ecuador, legalidad.Abstract: The arrival to power of Rafael Correa in 2007 involved various changes not only ideological but also political, channeled through a Constituent Assembly to conform to the precepts of the so-called "Citizen Revolution". The new Magna Carta established a greater number of executive controls and created new functions, such as the Electoral Power and Transparency and Social Control, which would also revolve around the decisions of the incumbent president. This, combined with the personality of Correa, generated a scenario of hyper-presidentialism, supported by popular elections that legitimize the changes made by the government. In the Ecuadorian case, what happened was a dissolution of legality through media action, in which the president's word was not only a rule of conduct, but also a perception that public activity cannot be discussed, exceeding its Constitutionally established competences. The present text, seeks to explore the mechanisms of existence of a decisionist discourse in the period of government 2013-2017 and its consequences in democratic governance, to demonstrate that the existence of an authority that escapes the power of the State can only be contained by the norm and the strength of democratic institutions, capable of improving the intensity of citizenship.Keywords: Hyperpresidencialism, Rafael Correa, Ecuador, Constitution, legality.

Published: March 2018

Abstract
Suspended solids (SS) in the storm-water makes up a significant source of total suspended solids in wet weather flow. With appropriate modification and maintenance, the standard sumps in the drainage system can remove SS from storm-water runoff as a best management practice device. To increase the removal efficiency, especially in the condition of high flow rate, inclined plates, based on the shallow pool sedimentation theory, have been designed and refitted to the sump. Its performance under the different surface load and flow rate were evaluated through scale models. The results show that the preliminary design, Model A, had limited removal efficiency, and even played a negative role sometimes due to the concentrated flow in the axis. The optimizations through installing a non-uniform porous baffle (Model B) and adopting inverted V-shaped plates (Model C) were improved, and results show that removal efficiency rate can be increased by around 15–20%, even at high flow rates. Moreover, too many plates cannot improve the removal rate further, because they make the cross-section decline and lead to higher velocity between plates.
The rate of denitrification using hydrodynamically disintegrated excess sludge as an organic carbon source
Authors: Walczak J. , Zubrowska-Sudol M. 
Published: March 2018

Abstract
This study investigates the potential of hydrodynamically disintegrated excess activated sludge when used as a supplementary carbon source for denitrification. Two objectives constituted this study: (i) to analyse the denitrification rate by using excess sludge subjected to hydrodynamic disintegration (HD), performed at different energy densities, as an organic carbon source, and (ii) to analyse the impact of hydrolysis of disintegrated sludge on the denitrification rate. Nitrate reduction tests were conducted to assess the denitrification rate for the following sources of organic carbon: thickened excess sludge disintegrated at three levels of energy density (70, 140 and 210 kJ/L), acetic acid solution and municipal wastewater after mechanical treatment. It was found that the HD of excess sludge conducted at different levels of energy density led to dissolved organic compounds characterised by various properties as donors of H+ in the denitrification process. The susceptibility of disintegrated sludge to anaerobic hydrolysis decreased along with the increasing energy density. The obtained organic carbon contributed to a lower increase in the denitrification rate in comparison to that when disintegrated sludge not subjected to hydrolysis was applied.

AbstractMicrobial desalination cell (MDC) is a propitious technology towards water desalination by utilizing wastewater as an energy source. In this study, a multi-chambered MDC was used to bioremediate steel plant wastewater using the same wastewater as a fuel for anodic bacteria. A pure culture of Pseudomonas putida MTCC 1194 was isolated and inoculated to remove toxic phenol. Three different inoculum conditions, namely P. putida (INC-A), a mixture of P. putida and activated sludge (INC-B), and activated sludge alone (INC-C) were employed in an anodic chamber to mainly compare the electricity generation and phenol degradation in MDCs. The study revealed the maximum phenol removal of 82 ± 2.4%, total dissolved solids (TDS) removal of 68 ± 1.5%, and power generation of 10.2 mW/m2 using INC-B. The synergistic interactions between microorganisms, can enhance the toxic phenol degradation and also electricity generation in MDC for onsite wastewater application.
