The increase of process stability in removing ammonia nitrogen from wastewater
Authors: Benáková Andrea , Johanidesová Iva , Kelbich Petr , Pospíšil Vojtěch , Wanner Jiří 
Published: March 2018

Abstract
This work focuses on the removal of ammonia nitrogen pollution from wastewaters in a two-stage laboratory model based on a combination of the nitritation and anammox processes with the biomass immobilized in a polyvinyl alcohol (PVA) matrix. Owing to the immobilization approach inside the PVA pellets, the bacterial activity remained nearly unchanged on an abrupt change in the environmental conditions. The nitritation kinetics were significantly dependent on the dissolved oxygen concentration. The critical dissolved oxygen concentration at which the nitritation process using the immobilized bacterial culture stops is 0.6 mg/L. The volumetric rate of nitrogen removal by the anammox bacteria was 158 mg/(L·d). The technology presented is well-suited for removing high ammonia nitrogen concentrations (≥300 mg/L).
Thermal-aware Output Polarity Selection Based on And-Inverter Graph Manipulation
Authors: Das Apangshu , Pradhan Sambhu Nath 
Published: March 2018

Background:
Output polarity of the sub-function is generally considered to reduce the area
and power of a circuit at the two-level realization. Along with area and power, the power-density is also
one of the significant parameter which needs to be consider, because power-density directly converges
to circuit temperature. More than 50% of the modern day integrated circuits are damaged due to
excessive overheating.

Methods:
This work demonstrates the impact of efficient power density based logic synthesis (in the
form of suitable polarity selection of sub-function of Programmable Logic Arrays (PLAs) for its multilevel
realization) for the reduction of temperature. Two-level PLA optimization using output polarity
selection is considered first and compared with other existing techniques and then And-Invert Graphs
(AIG) based multi-level realization has been considered to overcome the redundant solution generated
in two-level synthesis. AIG nodes and associated power dissipation can be reduced by rewriting,
refactoring and balancing technique. Reduction of nodes leads to the reduction of the area but on the
contrary increases power and power density of the circuit. A meta-heuristic search approach i.e., Nondominated
Sorting Genetic Algorithm-II (NSGA-II) is proposed to select the suitable output polarity of
PLA sub-functions for its optimal realization.

Results:
Best power density based solution saves up to 8.29% power density compared to ‘espresso –
dopo’ based solutions. Around 9.57% saving in area and 9.67% saving in power (switching activity) are
obtained with respect to ‘espresso’ based solution using NSGA-II.

Conclusion:
Suitable output polarity realized circuit is converted into multi-level AIG structure and
synthesized to overcome the redundant solution at the two-level circuit. It is observed that with the
increase in power density, the temperature of a particular circuit is also increases.

Published: March 2018

Background and objectives
Individuals receiving in-center hemodialysis experience a high symptom burden that detrimentally affects their quality of life. There are few evidence-based interventions for symptom relief in this population. To stimulate innovation in symptom management, data on patient symptom prioritization and treatment preferences are needed. We undertook this study to (1) identify patient-prioritized symptoms for the development of symptom relief therapies and (2) elicit preferences for treatments among individuals receiving hemodialysis.

Design, setting, participants, & measurements
We conducted a mixed methods study that included focus groups in Carrboro, North Carolina; Tucson, Arizona; and Seattle, Washington and a nationally distributed online survey. Focus group transcripts were analyzed for patterns, and the highest priority symptoms were determined on the basis of frequency and report severity. We used focus group findings to inform survey items. Focus group and survey results were crossvalidated and synthesized for final symptom prioritization.

Results
There were 32 participants across three focus groups and 87 survey respondents from 27 states in the United States. The physical symptoms of insomnia, fatigue, muscle cramping, and nausea/vomiting and the mood symptoms of anxiety and depressed mood were reported by participants in all focus groups. Among survey respondents, fatigue (94%), cramping (79%), and body aches (76%) were the most common physical symptoms, and feeling depressed (66%), worried (64%), and frustrated (63%) were the most common mood symptoms. The top-prioritized symptoms were consistent across focus group and survey participants and included the physical symptoms insomnia, fatigue, and cramping and the mood symptoms anxiety, depression, and frustration. Participants indicated that symptom frequency, duration, unpredictability, and social and financial effects factored most heavily into symptom prioritization.

Conclusions
Patients prioritized the physical symptoms of insomnia, fatigue, and cramping and the mood symptoms of anxiety, depression, and frustration as the top symptoms for which to find new therapies.

Abstract
This paper contains the results of the electric properties measurement of lentil set. Electric measurements with use of these materials are of fundamental importance in relation to the analysis of quantity of absorbed water and dielectric heating characteristics. The aim of this paper was to perform the measurements of conductivity, dielectric constant and loss tangent on samples of lentil, the electrical properties of which had not been sufficiently measured. Measurements were performed under various moisture contents, and the frequency of electric field ranged from 1 MHz to 16 MHz, using a Q meter with coaxial probe. It was concluded that conductivity, relative permittivity and loss tangent increased with an increase in moisture content, and dielectric constant and loss tangent decreased as the frequency of electric field increased.
Challenges (Obstacles) in Reaching Leadership Positions – Experiences of Women Professors at Novi Sad University Serbia
Authors: Andrić Marijana Mišić , Markov Slobodanka 
Published: March 2018

Abstract
Underrepresentation of women in leadership positions in universities is a phenomenon present in most countries of the world, with some significant differences. In our work we focused on obstacles that women professors in Novi Sad University (Serbia) faced in reaching leadership positions. Analysis is based on qualitative research using a semi structured interview, statistical data and selected secondary sources. Obstacles, mentorship and networking have been researched from an idiographic perspective (reflection and the personal experience of the women at Novi Sad University). Results indicate a significant underrepresentation of women in leadership positions at Novi Sad University. Findings point to a general pattern: the more power and authority the leadership position holds, the scarcer the number of women participating in it. According to interviewees’ statements the patriarchal value system makes the leadership positions difficult to attain for women. Interview analysis also suggests additional limiting factors, such as lack of mentorship and inadequate networking, acting as inhibitors in reaching leadership positions.

Abstract

BACKGROUND. Bacteriocins are peptides with antimicrobial efficacy produced by certain bacterial species. Probiotics indeed seem a promising method in the prevention of upper respiratory infections and our study would like to contribute to the results available in the literature, in order to underlie their true therapeutic potential role.

MATERIAL AND METHODS. Our multicenter pilot prospective study investigates 366 patients from September 2015 to February 2016. All the patients were treated with a topical device made up of a suspension of two specific bacterial strains: Streptococcus salivarius 24SMB and Streptococcus oralis 89a to be administered as nasal spray. The nasal spray was administered twice daily for 7 days per month for three consecutive months. A questionnaire about the subjective efficacy of the therapy correlated to an improvement of symptoms was also collected from patients.

RESULTS. After one year from the enrolment, a 70.07% reduction in the number of events compared with the number of expected episodes was observed.

CONCLUSION. The aim of our data is to propose a new therapeutic approach to treat the recurrence of upper airway infection and to support an adequate therapy in all cases where the traditional antibiotic therapeutic protocol did not obtain completely efficient results in terms of recurrence.

Published: March 2018

Abstract
The current study aims to investigate the effect of smartphone usage on the upper extremity performance among Saudi youth. A goniometer to measure the Range of Motion (ROM), the Smartphone Addiction Scale (SAS), McGill Pain scale and Chattanooga stabilizer were used to perform the current study on a sample of 300 university students from Al-Imam Mohammed Bin Saud University. The results have shown that smartphone addiction is negatively correlated to the elbow flexion, shoulder flexion, shoulder extension, shoulder abduction, shoulder adduction, and both shoulder internal and external rotation. Furthermore, the results have shown that McGill pain scores were positively correlated to elbow flexion, shoulder flexion, shoulder extension, shoulder abduction, shoulder adduction, and both shoulder internal and external rotation. The study has concluded that smartphone usage among Saudi youth negatively affects the upper extremity and causes a significant increase in the pain intensity. The study has recommended that there is an urgent need for a significant awareness campaign to warn the community regarding the impact of using smartphones for long periods of time.

El taller de cerámica como vehículo de intercambio en un territorio complejo.
Authors: Crespo Consuelo 
Published: March 2018

Memorias Tangibles de Tulipe (METATU) es una investigación, que usa los mecanismos de las prácticas participativas del arte, como vehículo de intercambio en un complejo campo de interacción al noroccidente de Pichincha, en un territorio demarcado por las huellas materiales dejadas por los Yumbos -pobladores antiguos- y por los afloramientos de arcilla en el borde de sus caminos y quebradas. El interés por el capital simbólico y por la construcción del “sentido”, en el territorio, se genera entre pugnas de los diferentes actores sociales: el Estado Desarrollista, el Estado Patrimonialista, la Iglesia y los actuales pobladores con sus diversos significantes. En esta investigación se prioriza la mirada del colono en relación con el espacio en su día a día, en la construcción de sus subjetividades y en su relación con el entorno. La investigación pretende mostrar el “campo” de la cultura específico de noroccidente, su multiplicidad y su antagonismo, atravesado por la “mirada” de las diferentes instancias de poder que franquean las visualidades en un “paisaje” que arrastra siglos de interacción entre lo humano y una naturaleza vulnerable.

Apolinére enameled (from) Álvaro Barrios, 1979-1980: la apropiación como hibridación cultural
Authors: Arias Albeiro 
Published: March 2018

Con base en los razonamientos de Néstor García Canclini en Culturas híbridas (1990) y “Noticias recientes sobre hibridación” (2000), y Juan Martín Prada en su texto La apropiación posmoderna (2001), este articulo aborda la obra Apolinére enameled (from) Álvaro Barrios (1979-1980), del artista colombiano Álvaro Barrios Vásquez (Cartagena de Indias, 27 de octubre de 1945), versión del ready-made asistido Apolinére enameled que fue realizado por Marcel Duchamp entre 1917 y 1918. Se trata de distensionar ciertos binarios como lo popular/culto y local/global, a partir de procesos de asimilación mutua, interrelación y de contaminación e hibridación cultural, para romper y relativizar conceptos como la linealidad histórica, lo autóctono, lo puro, lo auténtico, lo identitario, y por supuesto, lo original.
