Amaç
Bu çalışmada çocukluk çağı hastalıkları içinde sık görülen viral üst solunum yolu infeksiyonlarında C-reaktif protein düzeyi ve nötrofil/lenfosit oranının tanıda anlamlı olup olamayacağını araştırmayı hedefledik.
Gereç ve Yöntemler
Çalışma viral üst solunum yolu infeksiyonu tanısı almış 1-18 yaş aralığındaki çocuk hastaların kayıtları retrospektif olarak incelenerek yapıldı. Tam kan sayımı sonuçlarından nötrofil ve lenfosit değerleri tespit edildi. CRP referans değeri 5 mg/dL; Nötrofil/lenfosit oranı referans aralıkları 0–1, 1–2, 2–3, 3–4, 4–5 ve >5 olarak alındı. C-reaktif protein ve nötrofil/lenfosit oranı düzeyleri korelasyon analizi yöntemi ile karşılaştırıldı.
Bulgular
Yaşları bir ay ile 18 yaş arasında değişmekte olan 100 hasta, 52 kız (%52) 48 erkek (%48) kayıt edildi. Kız çocuklarının ortalama yaşı 6,42±0,69, erkek çocuklarının ise 5,52±0,66 olarak saptandı. Ortalama CRP kız çocuklarında 29,1±6,83, erkek çocuklarında 13,52±2,29; NLO değerleri ise kız çocuklarında 3,46±0,63, erkek çocuklarının ise 3,07±0,44 olarak tespit edildi. Kız ve erkek çocuklarda CRP değerinin 5 mg/dL’ den yüksek olduğu değer en fazla 5-9 yaş aralığında görüldü. CRP değerlerine göre erkek ve kızlar arasında anlamlı bir ilişki vardı. NLO değerleri ise 1-2, 2-4 ve 10-18 yaş kız ve erkekler arasında anlamlı bir farka sahipti (p< 0,001). CRP ve NLO değerleri korelasyon analizi ile değerlendirildiğinde, zayıf düzeyde anlamlı ilişkili oldukları saptandı (r= 0,263).
Sonuç
Pediatrik yaş grubunda akut üst solunum yolu infeksiyonlarında C-reaktif protein düzeyi ve nötrofil/lenfosit oranı anlamlı derecede artmıştı. Mevcut çalışmada, erken tanı ve tedaviye yardımcı olması adına pratik, ucuz ve kolay bir metod olan C-reaktif protein düzeyi ile nötrofil/lenfosit oranı vurgulandı.

Authors: Guseinova A. R. 
Published: November 2020

Objective. To study the significance of the presence and absence of carbohydrate metabolism disorders as a factor affecting the development of vitamin B12 deficiency.
Materials and methods. The data of 206 subjects, forming two main groups were analyzed: the group of carbohydrate metabolism disorders (CMDs), which included 76 women and 71 men (n = 147); the control group, which included 33 women and 26 men (n = 59). The inclusion criteria were the following: age over 35, availability of anamnestic data on pharmacotherapy, availability of data to clarify the state of carbohydrate metabolism, availability of data on vitamin B12 and some other biochemical indices. Vitamin B12 levels 221 pmol / l were considered normal, vitamin B12 levels from 148 pmol / l to 221 pmol/l were considered borderline (or mild deficiency), and levels of 148 pmol / l or less were considered severe vitamin B12 deficiency.
Results. The group of absent carbohydrate metabolism disorders included 59 persons and the group of carbohydrate metabolism disorders (CMDs) included T2DM patients (n = 123) and individuals with prediabetes (n = 24), i.e. the total number of the examined persons in CMD group was equal to 147. The average level of vitamin B12 in the control group (n = 59) was 401.6 and 138.06 pmol / l, and in CMD group (n = 147) it was equal to 342.1 133.10 pmol/l. The differences between the groups were statistically significant (p 0.01), that suggested the significance of CMDs as a risk factor for vitamin B12 deficiency. Vitamin B12 deficiency was combined with the presence of CMDs in 32 (21.8 %) cases. In 115 cases (78.2 %), the presence of CMDs was combined with the absence of vitamin B12 deficiency. In 8 cases (13.5 %), there were no CMDs, but there was vitamin B12 deficiency. In 51 cases (86.4 %), no CMDs and vitamin B12 deficiency was noted.
Conclusions. Despite the presence of a statistically significant decrease in vitamin B12 levels in CMD group (342.1 133.10 pmol / l vs 401.6 and 138.06 pmol/ l; p 0.01) and a high incidence rate of vitamin B12 deficiency in CMD group (21.8 % and 13.5 %, respectively), the study results do not allow us to consider the presence of CMDs to be the risk factor for vitamin B12 deficiency.

Published: November 2020

Los morteros de pega tienen como función integrar mampuestos en sistemas de mampostería, sin embargo, estos elementos constantemente son afectados por lesiones derivadas de la humedad como lo son las eflorescencias que ocasionan perdida de propiedades físicas como el color, la densidad y la masa debido a la afloración superfial de sales, acumulación interna de las mismas y desprendimientos superficiales; por lo anterior en esta investigación se estudió el uso de emulsión asfáltica como reductor de esta afectación. De acuerdo con los análisis realizados, se determinó que con adiciones de 10% y 20% de emulsión asfaltica se adquiere cierto grado de repelencia al agua y con adiciones de 30% y 40% se alcanzó hidrofobicidad completa. Además, se determinó que la emulsión asfáltica reduce la afloración de eflorescencias en un 27% con 10% de emulsión, del 47% con 20% y de 100% para muestras con 30% y 40% respectivamente. Aunque el uso de los aditivos bituminosos trae ciertas ventajas frente a las propiedades físicas de los morteros, inversamente reduce propiedades mecánicas como la resistencia a la compresión.
Gastrointestinal Myiasis Due to Sarcophaga argyrostoma (Diptera: Sarcophagidae) in Mashhad, Iran: a Case Report
Authors: Najjari Mohsen , Dik Bilal , Pekbey Gamze 
Published: November 2020

Myiasis is infection with a fly larva, usually occurring in tropical and subtropical areas. A 32-years-old immunocom­pro­mised woman with fever, gastrointestinal pain, cramps, vomiting; and fatigue was referred to Ghaem Hospital in Mash­had in July 2018. Entomological characterisation of cephaloskeletons, posterior spiracles of the excreted larvae and gen­ital dissection of male fly were diagnosed as Sarcophaga (Liopygia) argyrostoma. Accidental intestinal myiasis caused by unplanned intake of dipterous larvae by contaminated food staff or water. Patients with immune deficiency may be more at risk for the threat of maggot’s infestation, so in such cases, hospital standard should be more in atten­tion. To best of our knowledge, S. argyrostoma has not been reported before in the indexed literature from Iran.
Contralateral Upper Limb Weakness Following Botulinum Toxin A Injection for Poststroke Spasticity
Authors: Camões- Barbosa Alexandre , Ribeiro Inês Mendes , Medeiros Luisa 
Published: November 2020

Botulinum toxin type A has been approved for spasticity management in poststroke patients. The adverse effects are generally of two types: those related to local injection; and those related to the systemic effects from spread of the toxin. Contralateral weakness after botulinum toxin A treatment is a rarely reported adverse effect. We report the case of a 33-year-old female who had been receiving regular injections of incobotulinum toxin A due to spasticity of the right limbs after a hemorrhagic stroke. A switch was made to abobotulinum toxin A with an overall conversion ratio of 1:3.83. The patient presented contralateral upper limb paresis, especially of the deltoid muscle, in the second week post-injection. The electroneuromyography showed neuromuscular block due to botulinum toxin A. She recovered completely after eight months. A switch between different formulations of botulinum toxin type A should prompt caution when carrying out unit conversions. Distant side effects may appear, including paresis in the contralateral limbs.

A facile method to fabricate AC/CuO for efficient removal of organic pollutants by adsorption and persulfate-based advanced oxidation processes
Authors: Li Youlin , Hu Yu , You Wenqiao , Zhou Guangming , Peng Guilong 
Published: November 2020

Abstract
Activated carbon/CuO (AC/CuO) composites were prepared through a facile one-step hydrothermal method and used as a bifunctional material for adsorption and catalysis degradation of bisphenol A (BPA). The composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD). The obtained AC/CuO exhibited excellent adsorption and catalytic performance. The maximum adsorption capacity of BPA on the AC/CuO was 319.03 mg/g according to the Langmuir fitting. At an initial BPA concentration of 20 mg/L, the BPA degradation efficiencies were maintained above 96% for 15 min by using 20 mg/L AC/CuO and 2 mM peroxymonosulfate (PMS). Moreover, the relationship between adsorption and catalytic degradation was also investigated. The results indicated that the pre-adsorption disfavored the degradation reaction. This work not only provides a novel preparation method for AC/CuO catalyst, but also gives a deeper insight into the mechanisms between adsorption and catalytic degradation.

Published: November 2020

AbstractThis study sought to detect the global characteristics and developments of Fenton-based advanced oxidation processes (AOPs) focused on wastewater treatment. Using bibliometric and visualization analysis via VOSviwer, CiteSpace, and HistCite software, it investigated and analyzed different aspects, including growth trends, country, journal, category, and keyword analysis, as well as citation-burst detection of references to 5,940 records ranging from 1990 to 2019 in the Web of Science Core Collection. It was concluded that wastewaters in the textile industries, pharmaceutical industries, phenol compounds, and landfill leachates were currently and would continue to be the most focused industrial effluents that can be treated efficiently by applying Fenton-based AOPs. The study also conducted an in-depth analysis based on four clusters through the 100 most-occurring keywords, containing textile wastewater, catalyst, photo-Fenton, and electro-Fenton, identifying the four most studied research topics of Fenton-based AOPs. Studies about innovative (nano) catalysts, electrocatalytic, and photocatalytic materials can provide new degradation possibilities and overcome the Fenton process's drawbacks. The results of this bibliometric analysis can be helpful information for researchers and industry practitioners.

Published: November 2020

Abstract
The performance of a continuously operated laboratory-scale rotating biological contactor (RBC) was assessed for the removal of heavy metals viz. Cu(II), Cd(II) and Pb(II) from synthetic wastewater using artificial neural networks (ANNs). The RBC was inoculated with Sulfate Reducing Bacteria consortium (predominantly Desulfovibrio species), and the performance was evaluated at different hydraulic retention times (HRTs) and inlet heavy metal concentrations. A feed-forward back-propagation neural network model was developed using 90 data sets obtained over a period of three months, to predict the removal of heavy metal (HMRE) and COD (CODRE). The predictive capability of the model was evaluated in terms of the coefficient of determination (R) and mean absolute percentage error between the model fitted and actual experimental data, whereas sensitivity analysis was performed on the input parameters by determining the absolute average sensitivity (AAS) values. The higher AAS value of the HRT compared with that of inlet heavy metal concentration suggested that the change of HRT has a significant influence on HMRE and CODRE. Overall, the results obtained from this study demonstrated that ANNs can efficiently predict RBC behaviour with regard to heavy metal and COD removal characteristics under the prevailing operational conditions.
An ecological stability-oriented model for the conjunctive allocation of surface water and groundwater in oases in arid inland river basins

Published: November 2020

Abstract
With the continuous development of the population and social economy, the spatial and temporal distribution of water resources in arid inland river basins is severely uneven, and there is a sharp contradiction between agricultural water use and ecological water use. Irrational development and utilization of water resources has led to many problems, such as shrinking oases and drying lakes. To solve this problem, this study proposes a multiobjective, multiwater-source, ecological stability-oriented double-layer model for optimal allocation of water resources based on the large-scale system decomposition–coordination principle, the water balance principle, and a water supply and demand forecasting model. This model can resolve the contradiction between agricultural water use and ecological water use by optimizing and adjusting the crop planting structure, industrial structure, and the amount of water allocated to and groundwater level in each region and thereby achieve ecological stability and restoration of oases. The developed model was applied to the Heihe River Basin in an inland region of Northwest China. The long-term time series data of 2000–2016 were used to construct and calibrate the model. Finally, the practical ecological stability-oriented plan for conjunctive allocation of surface water and groundwater in different plan years was proposed. This model enriches the research results related to the conjunctive allocation of surface water and groundwater and provides a reference for the ecological restoration of oases in arid inland river basins.
Experimental study on the performance of modified flocculant (PEI-T) for removal of turbidity and heavy metals from aqueous solution
Authors: Jin-xi Wang , Singh Rajendra Prasad 
Published: November 2020

Abstract
The current study was focused on the evaluation of the performance of a modified flocculant (PEI-T) for the removal of turbidity and heavy metals from wastewater. Thioglycolic acid was introduced into the molecular chain of cationic flocculant polyethyleneimine (PEI) through an amidation reaction to form a new flocculant PEI-T. Results revealed that: (a) PEI-T and PEI had similar turbidity removal effect, but PEI-T had a good function of catching heavy metal copper and mercury; (b) when Cu2+ and turbidity-causing substances coexist in a water sample, Cu2+ and turbidity-causing substances promote the removal of each other and the residual concentration of Cu2+ and turbidity decrease further; and (c) the presence of Ca2+ and Mg2+ can promote the removal of copper ions by PEI-T.
Predicting failures in electronic water taps in rural sub-Saharan African communities: an LSTM-based approach
Authors: Offiong N. M. , Wu Y. , Memon F. A. 
Published: November 2020

Abstract
There is a growing need to sustain solar-powered water taps in most parts of the sub-Saharan Africa. The frequent failure of the water taps gives rise to intermittent water supply and poor service delivery by the water service providers. The challenge is to foresee and predict the failure of these water systems before they occur. This study develops a scalable machine-learning model for failure prediction in electronic water taps to ensure timely maintenance of the taps. Specifically, we develop a model based on long short-term memory (LSTM) to efficiently make failure predictions with noisy heterogeneous time-series data from rural water taps. Results from the experiment prove that the proposed model can effectively classify activities and patterns in various time-series datasets. With the proposed model, the failures of the solar-powered taps due to abnormal events can be successfully predicted well in advance, with an accuracy of 78.54%. Based on the data analyses, common causes of failures are presented.
