Published: October 2018

AbstractThis paper introduces the application of a fully dynamic air distribution model integrated with a biokinetic process model and a detailed process control model. By using a fully dynamic air distribution model, it is possible to understand the relationships between aeration equipment, control algorithms, process performance, and energy consumption, thus leading to a significantly more realistic prediction of water resource recovery facility (WRRF) performance. Consequently, this leads to an improved design of aeration control strategies and equipment. A model-based audit has been performed for the Girona WRRF with the goal of providing a more objective evaluation of energy reduction strategies. Currently, the Girona plant uses dissolved oxygen control and has been manually optimised for energy consumption. Results from a detailed integrated model show that the implementation of an ammonia-based aeration controller, a redistribution of the diffusers, and the installation of a smaller blower lead to energy savings between 12 and 21%, depending on wastewater temperature. The model supported the development of control strategies that counter the effects of current equipment limitations, such as tapered diffuser distribution, or over-sized blowers. The latter causes an intermittent aeration pattern with blowers switching on and off, increasing wear of the equipment.

Abstract
A facile approach has been developed to construct a composite of magnetic Fe3O4 (MNPs) and regular hexagon Mg-Al layered double hydroxide (MNPs/MgAl-LDH) via a two-step hydrothermal method combined with the urea hydrolysis reaction for the removal of Orange II. The scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy results showed MNPs and MgAl-LDH have been combined successfully, providing the combination of the superior properties of fast separation and high adsorption capacity. The pH values, contact time, initial dye concentration and temperature were investigated in detail. The kinetics and isotherm study showed the adsorption of Orange II on MNPs/MgAl-LDH obeyed the pseudo-second-order and Langmuir model respectively and the adsorption processes were spontaneous and endothermic in nature. Also, some coexisting anions such as Cl−, NO3−, CO3− and SO42− had no significant effect on the removal of Orange II. The mechanism study revealed that the adsorption of Orange II on MNPs/MgAl-LDH mainly involves surface adsorption through electrostatic force and the layer anion exchange. Moreover, Orange II could be desorbed from MNPs/MgAl-LDH using 100 mg L−1 NaOH and used for four cycles without any adsorption performance loss, demonstrating MNPs/MgAl-LDH prepared in this work could be used as a cost-effective and efficient material for the removal of Orange II.
Effects of sulfamethoxazole on the denitrifying process in anoxic activated sludge and the responses of denitrifying microorganisms
Authors: An Yonglei , Qin Xueming 
Published: October 2018

Abstract
The presence of antibiotics in municipal wastewater is bound to affect the anoxic denitrifying process in anoxic activated sludge (AAS). This study investigated the effects of sulfamethoxazole (SMZ) on the denitrifying process in AAS and the responses of denitrifying microorganisms. The results showed that SMZ could decrease the speed of nitrate removal significantly when the concentration of SMZ was lower than 10 mg/L, and the removal of nitrate would be completely inhibited when SMZ concentration was higher than 100 mg/L. Weak alkaline condition would enhance the inhibition effect of SMZ on removal of nitrate in the anoxic bioreactor. The results of high-throughput sequencing and qPCR (quantitative polymerase chain reaction) showed that 100 mg/L of SMZ did not decrease the total abundance of denitrifying microorganisms. However, the relative expression levels of key denitrifying genes NirS and NosZ in AAS treated by 100 mg/L of SMZ versus the raw AAS without SMZ was only 0.030 and 0.036. Therefore, the inhibitory mechanism of SMZ on the denitrifying process in AAS was denoted by an effective inhibition to the expressions of denitrifying genes, rather than a decrease in the total abundance of denitrifying microorganisms.

Abstract
Bacterium Acinetobacter baumannii is an emergent pathogen associated with nosocomial infections, which can be also found in natural waters. The impact of ecological factors on A. baumannii is insufficiently investigated. The aim was to examine the influence of temperatures (−20 to 80 °C) and pH values (2 to 12) on the survival of environmental and clinical isolates of A. baumannii in nutrient-deprived spring water (SW) and nutrient-rich diluted nutrient broth during 5 months. A. baumannii successfully survived at −20 to 44 °C and neutral pH for 5 months, which is consistent with the persistence of this pathogen in the hospital environment. At temperatures 50 to 80 °C the survival of A. baumannii ranged from 5 days to 5 min. The pH 2 was the most lethal with survival time up to 3 hours, suggesting that acidic conditions are promising for disinfection of water contaminated with A. baumannii. Although the type of media was not statistically significant for long-time survival, the extensively resistant or pandrug-resistant isolates survived better in SW than susceptible or multidrug-resistant isolates. Two distinct colony phenotypes were recorded at extreme temperatures and pH values. The results of this study provide insight into the behaviour of this emerging pathogen in the environment.
Electroflotation of oily wastewater using stainless steel sponge electrodes
Authors: Genc A. , Goc S. 
Published: October 2018

Abstract
In this study, emulsified oil removals have been studied electrochemically by using stainless steel sponge electrode beds. A first-order electroflotation model was developed and the model estimation were consistent with the experimental results. It was found out that the mean electroflotation rate constant was mainly a function of the voltage applied to the electrode beds. In addition, the properties of intermediate materials (electrical conductivity) placed between the anode and cathode electrode beds strongly affected removal yields. For the initial concentration of 57,150 mg/L, the chemical oxygen demand (COD) removal was obtained as 85% under the conditions of voltage gradient 15 V. The experiments were also performed by varying the electrode bed lengths. Even though higher oil yields were obtained at 27 cm bed length, similar oil yields were also obtained at 18 cm bed length, especially after 60 min, with less energy consumption. Therefore, the optimum electrode bed length was concluded to be 18 cm.

Актуальність. Близько 6–8 % всіх інсультів становить субарахноїдальний крововилив (САК) внаслідок розриву артеріальної аневризми. 10–15 % із них є фатальними, тобто пацієнт помирає ще до того, як надійшов до стаціонару. За даними деяких авторів, судоми в гострий період САК (перші 7 діб) асоціюються із збільшенням ризику смерті й інвалідності, тоді як інші автори заперечують вплив судом на перебіг САК. З огляду на суперечливість цих даних судоми не входять у класичні шкали з оцінки прогнозу перебігу САК. Мета: провести аналіз поширеності гострого симптоматичного епінападу при САК і дослідити його вплив на перебіг цього захворювання. Розробити прогностичну шкалу оцінки САК з урахуванням судомних нападів. Матеріали та методи. Проведено аналіз серії 127 клінічних випадків САК. Усіх пацієнтів оцінено за стандартними шкалами: Hunt — Hess Scale, the World Federation of Neurological Surgeons Scale, Glasgow Coma Scale. Досліджено поширеність гострого симптоматичного епінападу. Всіх пацієнтів оцінено за створеною шкалою комбінованої оцінки прогнозування наслідку у пацієнта після субарахноїдального крововиливу (ШКОП). Результати лікування оцінено за Glasgow Outcome Scale (шкала наслідку Глазго). Результати. У 13 пацієнтів із 127 спостерігалися судоми в гострий період захворювання. У кожного 10­го пацієнта епілептичний напад був першим клінічним симптомом хвороби. Поширеність епілептичних нападів становила 10,2 %, до того ж у 5 з 13 пацієнтів із судомами САК закінчився летально, що станоить 35,7 % всіх летальних випадків, зафіксованих у нашій групі пацієнтів. Запропоновано враховувати судоми в дебюті САК як ізольований предиктор поганого наслідку у пацієнтів. Розроблено ШКОП, до якої включено критерій наявності/відсутності судом у дебюті. Летальність серед пацієнтів, які набрали 5–6 балів за ШКОП, становила 77 %, серед пацієнтів, які набрали 7–8 балів, — 100 %. Висновки. Судомний напад у дебюті САК асоціюється з вірогідним підвищенням ризику смерті (p = 0,001). ШКОП із субарахноїдальним крововиливом дозволяє прогнозувати перебіг захворювання, що сприяє вчасним корекції лікування, призначенню швидкодіючих парентеральних антиконвульсантів і, відповідно, визначає кращий наслідок у пацієнтів.

Robust Controlled Positive Delayed Systems with Interval Parameter Uncertainties: A Delay Uniform Decomposition Approach
Authors: Elloumi Wafa , Mehdi Driss , Chaabane Mohamed 
Published: October 2018

Abstract
This paper is concerned with robust stabilization of continuous linear positive time-delay systems with parametric uncertainties. The delay considered in this work is a bounded time-varying function. Previously, we have demonstrated that the equidistant delay-decomposition technique is less conservative when it is applied to linear positive time-delay systems. Thus, we use simply a delay bi-decomposition in an appropriate Lyapunov-Krasovskii functional. By using classical and partitioned control gains, the state-feedback controllers developed in our work are formulated in terms of linear matrix inequalities. The efficiency of the proposed robust control laws is illustrated with via an example.
Applications of A Hyper–Graph Grammar System in Adaptive Finite–Element Computations

Published: October 2018

Abstract
This paper describes application of a hyper-graph grammar system for modeling a three-dimensional adaptive finite element method. The hyper-graph grammar approach allows obtaining a linear computational cost of adaptive mesh transformations and computations performed over refined meshes. The computations are done by a hyper-graph grammar driven algorithm applicable to three-dimensional problems. For the case of typical refinements performed towards a point or an edge, the algorithm yields linear computational cost with respect to the mesh nodes for its sequential execution and logarithmic cost for its parallel execution. Such hyper-graph grammar productions are the mathematical formalism used to describe the computational algorithm implementing the finite element method. Each production indicates the smallest atomic task that can be executed concurrently. The mesh transformations and computations by using the hyper-graph grammar-based approach have been tested in the GALOIS environment. We conclude the paper with some numerical results performed on a shared-memory Linux cluster node, for the case of three-dimensional computational meshes refined towards a point, an edge and a face.

Published: October 2018

Abstract
Introduction: Atrial fibrillation (AF) is the most frequent cardiac rhythm disorder, considered until recently benign. Due to its major complications (cardio-embolic episodes) patients need to be anticoagulated. Aim: To assess the quality of life (QOL) in patients with new oral anticoagulants (NOAC) versus those using classical anticoagulants (VKA). Methods: A total of 483 patients admitted consecutively in our clinic were evaluated during hospitalization and after discharge. Follow-up visits were conducted: at baseline, 6, 12, 18 and 24 months; the quality of life (QoL) was measured by a specific questionnaire (EQ-5D-3L), and the results were assessed. Patients were divided in two groups considering their anticoagulant use: NOAC or VKA. Baseline characteristics, clinical outcomes as well as QoL indices were compared between the two groups The current research has been conducted in accordance with the ethical prin ciples set out in the Helsinki Declaration and Good Clinical Practice Recommendations and was approved by our hospital Ethics Committee. Results: The mean age of our studied group (374 eligible patients) was 64.7 ± 8.2 years (p=0.220); 116 patients (31.01%) used NOAC. Patients with NOAC obtained better results in all domains: physical (57.0±8.9 vs. 51.1±12.5 vs. 42.0±6.2; p<0.001), social (62.6±19.8 vs. 52.5±20.0 vs. 45.7±16.0; p=0.019) and environmental (62.9±12.7 vs. 52.7±7.6 vs. 60.7±3.6; p =0.018). Compared to VKAs, NOACs were more commonly prescribed in patients with a history of stroke or with a higher thromboembolic risk (p<0.001). EQ-5D-3L total score: 75.6 ± 20.9; visual analogue scale: 63.1 ± 20.6. Conclusion(s): Satisfaction and QoL with oral anticoagulants were high, although they were both better with NOACs. A worse QoL was associated with comorbidities, polypragmasy, and previous treatment with VKA. Patients strongly expressed their desire to improve their QoL.
Use of functional cluster analysis of CPTU data for assessment of a subsoil rigidity
Authors: Młynarek Zb. , Wierzbicki J. , Wołyński W. 
Published: October 2018

Abstract
This paper shows an example of the grouping of piezocone penetration test (CPTU) characteristics using functional data analysis, together with the results of clustering, in the form of a subsoil rigidity model. The subsoil rigidity model was constructed based on layer separation using the proposed method, as well as the k-means method. In the construction of the subsoil rigidity model, the constrained modulus M was applied. These moduli were determined from empirical relationships for overconsolidated and normally consolidated soils from Poland based on cone tip resistance.
Black Feminism’s Minor Empiricism: Hurston, Combahee, and the Experience of Evidence
Authors: Andrews Lindsey 
Published: October 2018

In this article, I argue that the Zora Neale Hurston’s early twentieth-century anthropological work and the Combahee River Collective’s 1977 Black Feminist Statement can be read as part of a genealogy of Black feminist empiricism: a minor empiricism that rejects positivist empiricism, strategically mobilizing dominant scientific practices while also developing an onto-espistemology specific to Black English and what Combahee terms “black women’s style.” Their works make tactical use of positivist empirics to critique and counter legal and medico-scientific circumscription of Black women’s lives, while simultaneously participating in this counter-practice of Black feminist empiricism. As both Combahee’s statement and Hurston’s first ethnography, Mules and Men (1935), reveal, Black feminist empiricism is grounded not in traditional scientific virtues such as transparency and objectivity, but instead in opacity and subjectivity, which make it unavailable for use for purposes of legal subjection, while simultaneously revealing the raced and gendered implications of a legal system dependent on positivist values.
Simulated War: Remediating Trauma Narratives in Military Psychotherapy
Authors: Brandt Marisa Renee 
Published: October 2018

How have the politics of therapy been reconfigured during the so-called Global War on Terror? What role have the new virtual reality therapies that so resemble other forms of military simulation played in this reconfiguration? In this article, I draw upon feminist science and technology’s (STS) theorization of human-machine interaction into order to interrogate how contemporary therapies for treating post-traumatic stress disorder (PTSD) reconfigure agency in the practice of healing. Analyzing trauma therapy as a site of reconfiguration, I show how new exposure-based therapies for PTSD—both with and without virtual reality—configure aspects of human subjectivity, such as memory, affect, and behavior, as objects for technological intervention. Through comparative analysis of different modalities of PTSD treatment, I show that the politics of therapy is especially enacted through the therapeutic remediation of trauma narratives: the mediational practices through which a traumatic memory is made available for therapeutic reworking. Therapeutic remediation practices configure therapists, patients, and nonhuman actants as subjects and objects with different forms of agency.

Актуальність дослідження зумовлена суперечністю між потребою в компетентних спеціалістах у сфері фізичної культури, туризму та рекреації й недостатніми моделями їх підготовки, зокрема з дисципліни «Рекреаційний туризм». Мета дослідження – розробити модель оптимального освітнього процесу навчання рекреаційному туризму студентів факультетів фізичної культури з напряму рекреаційного туризму. Методи дослідження – анкетування, теоретичне моделювання, аналіз й узагальнення літературних джерел, педагогічне спостереження, метод математичної статистики. Результати роботи. Установлено, що професійна підготовка майбутніх фахівців рекреаційного туризму визначається як процес, що відображає науково та методично обґрунтовані освітньо-виховні заходи вищого закладу освіти, які мають теоретичний і практичний характер. Дані дослідження засвідчили, що під час вивчення навчального предмету «Рекреаційний туризм» студенти надають перевагу практичним заняттям, інформаційним лекціям (26,9 %), лекціям-візуалізаціям (26,9 %), лекціям-дискусіям (22,6 %), зустрічам із практиками в галузі рекреаційного туризму, відвідуванню екскурсій, туристичних об’єктів, турагентств тощо. Науковці також рекомендують доповнювати систему освіти підготовки таких фахівців такими методами навчання, як проблемні ситуації, ділові ігри, Інтернет-тренінги, конференції, та створювати міжпредметні зв’язки з іноземними мовами, економікою й менеджментом. Щодо розділів дисципліни, які б студенти хотіли опанувати передусім на практичному рівні, то найбільшу зацікавленість відзначено в активних видах туризму, таких як спортивний, зокрема пішохідний, туристичних послугах, краєзнавстві та туристичній анімації. Висновки. Отже, формування ефективної моделі профільної підготовки студентів факультетів фізичної культури й здоров’я, саме комплексність в організації навчального процесу з рекреаційного туризму, урахування думки студентів, колег і напрацювання теоретиків та практиків щодо підбору змісту, методів і форм занять, способів оцінки знань, дасть змогу підвищити рівень знань та мотивацію до вивчення цієї дисципліни.
