Utilizing variable selection methods in modelling potable water quality
Authors: Tomperi Jani , Leiviskä Kauko 
Published: October 2018

Abstract
Predictive models are potential tools for assessing changes in a water treatment process and water quality, and to be used as assistance in process control to ensure the production and distribution of high quality drinking water to consumers with lower operation costs. In this work, mathematical variable selection methods were utilized to find the optimal subsets of variables to develop predictive models for the two quality parameters of drinking water. The found variable subsets were evaluated using three modelling methods and comparisons with the expert knowledge-based models were carried out. The study pointed out the importance of expert knowledge and showed that predicting the quality of treated water is possible but finding an optimal subset of input parameters for a model that predicts the precise value of a quality parameter is challenging.
Photocatalytic removal of fluoroquinolones and their antimicrobial activity from water matrices at trace levels: a comparison of commercial TiO2 catalysts
Authors: Venancio Wilson Augusto Lima , Rodrigues-Silva Caio , Maniero Milena Guedes , Guimarães José Roberto 
Published: October 2018

Abstract
In this study, a solution containing the fluoroquinolones (FQs) ciprofloxacin, lomefloxacin, and ofloxacin (antimicrobial agents) was subjected to photocatalytic oxidation under UVA irradiation, employing the commercial titanium dioxide as catalyst. On-line solid phase extraction coupled to ultra-high-performance liquid chromatography–mass spectroscopy was used to pre-concentrate and quantify the analytes. The process provided an almost 95% degradation efficiency for all the FQs. The TiO2 PC500 (100% anatase) was more efficient than TiO2 P25 (80% anatase) for FQs degradation. The matrix effect on the efficiency of the process was evaluated by ultrapure water – UW, simulated water – SW, bottled water –BW, and public drinking tap water – TW. Simulated water showed lower interference, compared to drinking water and bottled mineral water, due to the lower concentrations of hydroxyl radical scavengers. The assessment of the residual antimicrobial activity in the solution, when using 50 mg L−1 PC500 or 100 mg L−1 P25, showed reductions of biological activity (after 120 min of reaction) of 92.4% and 95.4% for Escherichia coli, and 78.1% and 84.2% for Bacillus subtilis, respectively. It shows that the photocatalytic oxidation process was able to not only degrade the FQs but also deactivate its biological activity in the resultant solution.

Authors: Ramos Susie Medeiros	Oliveira , Glavam Adriana Pereira , de Brito Adriana Soares	Xavier , Kubo Tadeu Takao Almodovar , Tukamoto Gustavo , Sampaio Debora da Cunha Pereira , de Sá Lidia Vasconcellos 
Published: October 2018

Background:
Soft tissue attenuation artifacts are the most common cause of misinterpretation
in myocardial perfusion Imaging (MPI). Few studies assessing the value of prone imaging
in women have been published. Breast attenuation artifacts can be present in up to 40% of the MPI
studies in women.

Objectives:
This study aimed at evaluating the potential impact of prone MPI on breast attenuation,
with a critical analysis of activity optimization and breast size influence.

Methods:
MPI of an Anthropomorphic Torso Phantom with silicone breast prostheses and
equivalent adipose tissue was compared to a standard MPI database.

Results:
A medical qualitative and semiquantitative analysis demonstrated higher uptake in the LV
anterior segments in the prone position for all injected activities. An artificial myocardium lesion
was diagnosable in the right segment in all images, which shows that prone positioning would not
mask a true lesion and it assists the cardiologist with a more accurate analysis. These results
showed that it is possible to optimize the activity to be injected by up to 55.6% when using combined
supine-prone images.

Conclusion:
Prone position has a high impact on the interpretation of MPI in female patients since
it reduces the breast attenuation artifacts, and optimizes the radiation protection of the patient and
all staff involved in the procedure, making it more cost-effective.
Knee Meniscus Segmentation and Tear Detection from MRI: A Review
Authors: Saygili Ahmet , Albayrak Songül 
Published: October 2018

Background:
Automatic diagnostic systems in medical imaging provide useful information
to support radiologists and other relevant experts. The systems that help radiologists in their
analysis and diagnosis appear to be increasing.

Discussion:
Knee joints are intensively studied structures, as well. In this review, studies that
automatically segment meniscal structures from the knee joint MR images and detect tears have
been investigated. Some of the studies in the literature merely perform meniscus segmentation,
while others include classification procedures that detect both meniscus segmentation and anomalies
on menisci. The studies performed on the meniscus were categorized according to the methods
they used. The methods used and the results obtained from such studies were analyzed along with
their drawbacks, and the aspects to be developed were also emphasized.

Conclusion:
The work that has been done in this area can effectively support the decisions that will
be made by radiology and orthopedics specialists. Furthermore, these operations, which were performed
manually on MR images, can be performed in a shorter time with the help of computeraided
systems, which enables early diagnosis and treatment.

Authors: Pei Lizhai , Qiu Fanglv , Ma Yue , Lin Feifei , Fan Chuangang , Ling Xianzhang 
Published: October 2018

Context:
Benzoic acid is a kind of extensively used preservative. It is of great significance to
detect benzoic acid by a rapid method for quality assurance and protection in the fields of pharmaceutical,
food and chemistry industry.

Objective:
The present research is aimed to prepare polyaniline/Al bismuthate composite nanorods by
an in-situ polymerizing process for effective detection of benzoic acid.

Methods:
The polyaniline/Al bismuthate composite nanorods are prepared by an in-situ polymerizing
process. The structure, morphology and electrochemical performance of the obtained polyaniline/Al
bismuthate composite nanorods are analyzed by X-ray diffraction (XRD), transmission electron microscopy
and electrochemical measurement.

Results:
XRD and transmission electron microscopy observations show that the amorphous nanoscale
polyaniline particles attach to the surface of the crystalline nanorods. The electrochemical measurement
of 2 mM benzoic acid using the composite nanorods modified glassy carbon electrode (GCE) shows
that a pair of semi-reversible CV peaks is located at -0.11 V (cvp1) and -0.48 V (cvp1′), respectively.
The electrochemical responses of 2 mM benzoic acid at the composite nanorods modified GCE are
enhanced with increasing the scan rate and benzoic acid concentration. The polyaniline/Al bismuthate
composite nanorods modified GCE shows a linear range of 0.001-2 mM with the limit of detection
(LOD) of 0.18 µM.

Conclusion:
The composite nanorods may be used as the electrode materials with good reproducibility
and stability for the detection of benzoic acid.

Published: October 2018

Background:In bio-reactor landfills, both moisture and temperature have a significant impact on the bio-degradation processes. In order to speed up the leachate recirculation, a new drainage system is proposed to build a space network of bonded whole waste tyres in landfills.Objective:In this study, a coupled dual-permeability flow and the heat transfer model was constructed to study the interaction between leachate migration and temperature evolution.Results and Conclusion:The established model was applied to a simplified bio-reactor landfill and the simulation results demonstrated that the presence of waste tyres could significantly speed up the heat transfer. And the intermittent injection and the varying injection pressure might affect the distribution of temperature as well. Additionally, cooling the leachate injected could be another measure in avoiding the occurrence of hot spots in landfills.

Published: October 2018

Introduction:
Sickle cell disease is a haemoglobinopathy characterized by the occurrence of vaso-occlusive crises and osteoarticular complications.

Case-Report:
We report the case of an infant with sickle cell disease revealed by a bilateral abscess of the feet. Our patient is an 18-month-old infant who has had bilateral swelling of the feet for a week with fever of 40 °C, a CRP of 129 mg/l and a leukocytosis of 32,000 elements/mm3 together with normochromic normocytic anemia at 7.9 g/dl.
The diagnosis of abscess was taken and a puncture was made finding a purulent fluid with isolation of Salmonella. In front of the bilateral character, Salmonella isolation and normochromic normocytic anemia, electrophoresis of hemoglobin was requested confirming the diagnosis of sickle cell disease. The progress was positive with hydration and antibiotic therapy.

Conclusion:
Soft-tissue Salmonella infections must lead to thinking of sickle cell disease as a diagnosis especially with normochromic normocytic anemia combined.
Susceptibility Status of Aedes aegypti L. Against Different Classes of Insecticides in New Delhi, India to Formulate Mosquito Control Strategy in Fields
Authors: Samal Roopa Rani , Kumar Sarita 
Published: October 2018

Background:
Mosquito control is a major concern throughout the world because of rising cases of mosquito-borne diseases. The outbreak of Zika, Dengue and Chikungunya has caused grave situations raising urgent need to control Aedes aegypti. Moreover, extensive use of synthetic insecticides in mosquito control programs has resulted in high levels of insecticide resistance leading to the use of magnified concentrations, impacting human health and environment adversely. The knowledge about current status of the insecticide susceptibility against Ae. aegypti could help to devise mosquito control strategy.

Objective:
Present study evaluates the larvicidal potential of thirteen insecticides belonging to seven different classes; organochlorines, organophosphates, carbamates, pyrethroids, neonicotinoids, avermectins and secondary metabolites; against early fourth instars of Ae. aegypti.

Materials and Methods:
The insecticide susceptibility was evaluated as per WHO protocol. Fatality counts were made after 24h of exposure; and the LC50, LC90 and other statistical parameters were computed by probit-regression analysis.

Results:
The data reveals the maximum efficacy of pyrethroids and fenitrothion, with lethal values less than 0.001 ppm. Avermectins, organochlorines and carbamates were moderately toxic, while neonicotinoid posed appreciable toxicity. In contrast, berberine, a secondary plant metabolite was found inefficient. The larvicidal efficacy of tested insecticides against Ae. aegypti was found in the decreasing order of pyrethroids > organophosphates > avermectins > organochlorines > carbamates > neonicotinoids > secondary metabolites.

Conclusion:
Present investigations explore various toxicants as Dengue vector control agents in order to devise a suitable control strategy for mosquito control in fields.
Magnetic Resonance Imaging Findings of Term and Preterm Hypoxic-Ischemic Encephalopathy: A Review of Relevant Animal Models and Correlation to Human Imaging
Authors: Jisa Kyle A. , Clarey Dillon D. , Peeples Eric S. 
Published: October 2018

Background:Neonatal hypoxic-ischemic encephalopathy is brain injury caused by decreased perfusion and oxygen delivery that most commonly occurs in the context of delivery complications such as umbilical cord compression or placental abruption. Imaging is a key component for guiding treatment and prediction of prognosis, and the most sensitive clinical imaging modality for the brain injury patterns seen in hypoxic-ischemic encephalopathy is magnetic resonance imaging.Objective:The goal of this review is to compare magnetic resonance imaging findings demonstrated in the available animal models of hypoxic-ischemic encephalopathy to those found in preterm (≤ 36 weeks) and term (>36 weeks) human neonates with hypoxic-ischemic encephalopathy, with special attention to the strengths and weaknesses of each model.Methods:A structured literature search was performed independently by two authors and the results of the searches were compiled. Animal model, human brain age equivalency, mechanism of injury, and area of brain injury were recorded for comparison to imaging findings in preterm and term human neonates with hypoxic-ischemic encephalopathy.Conclusion:Numerous animal models have been developed to better elicit the expected findings that occur after HIE by allowing investigators to control many of the clinical variables that result in injury. Although modeling the same disease process, magnetic resonance imaging findings in the animal models vary with the species and methods used to induce hypoxia and ischemia. The further development of animal models of HIE should include a focus on comparing imaging findings, and not just pathologic findings, to human studies.

Authors: Jatmiko Agus 
Published: October 2018

Migration is a form of migration that can be seen in several regions in Indonesia. Wandering not only occurs in finding work but also in students who will continue their education in college. Migrant students will experience situations that are different from life in their place of origin, for example differences in culture, language and communication. As social beings we cannot be separated from interaction, where in this interaction a special feeling will be formed that is received by humans produced from a place with various elements in it, including those who live in it, this special feeling is called the sense of place . In interacting not all individuals feel safe and comfortable, but there are also those who have feelings of anxiety, fear, or worry about the surrounding environment, ­­­­ anxiety or concern related to social situations is called social anxiety. This study uses quantitative research methods with the subject of 90 students from Tarbiyah and Teaching Faculty of Lampung State Islamic University as chosen by using the sample technique, namely purposive sampling. Data collection uses a questionnaire about the variable sense of place and social anxiety variables . Hypothesis testing in this study uses Product Moment correlation analysis . The conclusion of the study is that there is a relationship between the sense of place and social anxiety on students from the Tarbiyah Faculty of Education and Teacher Training at the State Islamic University Raden Intan Lampung.

Published: October 2018

En este trabajo se evalua un método analítico para calcular la frecuencia natural fundamental y la pseudo-aceleración de losas de vigueta y bovedilla prefabricada. La frecuencia natural por vibración libre y la pseudo-aceleración por vibración forzada debida al caminar de personas. Se realiza un estudio experimental y uno numérico de dos especímenes para obtener sus respuestas dinámicas. Se comparan las pruebas experimentales con soluciones analíticas y numéricas. Uno de los especímenes se probó en laboratorio y el otro en un edificio de mampostería confinada destinado a vivienda. De la evaluación realizada se observa que las soluciones tanto analíticas como numéricas en la obtención de la frecuencia natural fundamental son adecuadas. Sin embargo, la aceleración máxima calculada debida al caminar de personas difiere entre cada aproximación. Por lo que es necesario utilizar una carga dinámica representativa para modelar adecuadamente el caminarde personas.
