A hybrid linear–nonlinear approach to predict the monthly rainfall over the Urmia Lake watershed using wavelet-SARIMAX-LSSVM conjugated model
Authors: Farajzadeh Jamileh , Alizadeh Farhad 
Published: August 2017

Abstract
The present study aimed to develop a hybrid model to predict the rainfall time series of Urmia Lake watershed. For this purpose, a model based on discrete wavelet transform, ARIMAX and least squares support vector machine (LSSVM) (W-S-LSSVM) was developed. The proposed model was designed to handle linear, nonlinear and seasonality of rainfall time series. In the proposed model, time series were decomposed into sub-series (approximation (a) and details (d)). Next, the sub-series were predicted separately. In the proposed model, sub-series were fed into SARIMAX to be predicted. The residual of predicted sub-series (error) of the rainfall time series was then fed into LSSVM to predict the residual components. Then, all predicted values were aggregated to rebuild the predicted time series. In order to compare results, first a classic modeling was performed by LSSVM. Later, wavelet-based LSSVM was used to capture the peak values of rainfall. Results revealed that Daubechies 4 and decomposition level 4 (db(4,4)) led to the best outcome. Due to the performance of db(4,4), it was selected to be applied in the proposed model. Based on results, it was observed that the W-S-LSSVM's performance was improved in comparison with other models.
Compressed sensing based optimal sensor placement for leak localization in water distribution networks
Authors: Xie Xiang , Zhou Quan , Hou Dibo , Zhang Hongjian 
Published: August 2017

Abstract
The performance of model-based leak detection and localization techniques heavily depends on the configuration of a limited number of sensors. This paper presents a sensor placement optimization strategy that guarantees sufficient diagnosability while satisfying the budget constraint. Based on the theory of compressed sensing, the leak localization problem could be transformed into acquiring the sparse leak-induced demands from the available measurements, and the average mutual coherence is devised as a diagnosability criterion for evaluating whether the measurements contain enough information for identifying the potential leaks. The optimal sensor placement problem is then reformulated as a {0, 1} quadratic knapsack problem, seeking an optimal sensor placement scheme by minimizing the average mutual coherence to maximize the degree of diagnosability. To effectively handle the complicated real-life water distribution networks, a validated binary version of artificial bee colony algorithm enhanced by genetic operators, including crossover and swap, is introduced to solve the binary knapsack problem. The proposed strategy is illustrated and validated through a real-life water distribution network with synthetically generated field data.

Published: August 2017

Abstract
Dividing a water distribution network (WDN) into district metered areas (DMAs) is the first vital step towards pressure management and real losses reduction. However, other factors of water quality such as the water age must be taken into account while forming DMAs. The current study uses genetic algorithm (GA) optimization methods to achieve the desired WDN segmentation conditions in terms of: (a) reducing the operating pressure, thus reducing the system's real losses; and (b) reducing the water age, thus improving the feeling of water freshness and preventing growth of disinfection byproducts. Techniques based on GA are a proven way to provide a very good solution to optimization problems. The solution is obtained using an objective function and setting boundary constraints. The formation of the objective functions is tested through Matlab's optimization toolbox. The logic of the objective functions' formulation for both the operating pressure and the water age optimization is recorded and analyzed. The method's application utilized a sample network model assisted by EPANET and Bentley's WaterGEMS software tools. The morphology of the DMAs is presented for each scenario, as well as the results of the network's segmentation according to the operating pressure and the water age.

Abstract
Dividing a water distribution network (WDN) in the optimal district metered areas (DMAs) formation is one task that usually troubles water utility managers. The present paper utilizes optimization methods to achieve desired segmentation conditions in terms of (a) operating pressure reduction, thus reducing the system's real water losses and (b) residual chlorine concentration reduction thus preventing disinfection byproducts' growth. Exploiting the numerous possibilities offered by the inter-connection of Matlab and EPANET software tools, an algorithm is developed in C++ language. The algorithm reads all significant data of a WDN as an output of EPANET. The first algorithm calculates the optimal allocation of a given number of closed isolation valves in terms of water losses' reduction, considering restrictions for network's proper operation. The second algorithm calculates the optimal formation of DMAs in terms of water quality improvement. Both algorithms can be applied in any WDN. The outcome is the optimal set of closed pipes that leads to the optimal formation of DMAs in a given network. The closing of pipes (by installing isolation valves) determines the optimal formation of DMAs. The basic concept of both algorithms and their application in a case study network's hydraulic model are presented.

Medical waste management is of crucial importance in health care facilities (HCF). In the present study, we assessed the knowledge, attitude and practices of medical waste management in an HCF of Sulaimani city, Kurdistan Region of Iraq. Using a self-administered questionnaire, we collected information on waste management practices from health care professionals (HCP) in 14 public and private hospitals and 10 primary health care centers of the city. Based on answers, total knowledge score on a 10-point scale was established. A total of 406 HCPs (of those, 261 women), average age 37.3 (SD ± 9.4) years participated. Just 20.3% have been trained on medical waste management. The total knowledge score ranged from 0 to 9 with a mean of 4.7 (SD ± 1.8). Factors which were significantly associated with the better knowledge score was male gender, having a high educational degree, being trained in waste management and has been in service for more than 5 years. 68% of HCPs followed the color coding system, 91% always/frequently disposed used sharps/needles to safety boxes, 79% always or frequently recapped needles, 49% reported experiencing at least one needle prick injury during their work but only 37% of them had reported the injury to a supervisor and only 4% of those injured had filled an injury form. There is a low average level of knowledge and the unsafe risky practices are quite prevalent in HCFs. Provision of appropriate training on dealing with medical waste is essential to promote safe practices among HCFs.
La aplicación de la ecología del paisaje al espacio público de las ciudades colombianas
Authors: Artunduaga Tadeo Sanabria 
Published: August 2017

El espacio libre juega un papel básico como soporte de los procesos ecológicos y en la integración armónica del suelo rural y el urbano. El reconocimiento de las funciones ambientales y territoriales del espacio público y de las áreas no urbanizadas obliga a implementar nuevas formas de ordenar y diseñar la ciudad, y en esa dirección, la adopción de planteamientos teóricos y metodológicos vinculados a la Ecología del paisaje, pueden facilitar la práctica hacia ciudades más sostenibles. El presente documento da cuenta de una experiencia reciente de apoyo al paisajismo y al ordenamiento en el contexto colombiano: el diseño de la articulación formal y funcional de los elementos constitutivos de la estructura ecológica principal urbana en el municipio de La Calera (Cundinamarca). Este proyecto es complementado con la vinculación de la gestión pública en torno a los árboles, bajo una propuesta que armoniza el Plan Distrital de Silvicultura con los planes maestros de Bogotá

Published: August 2017

Este artículo de reflexión presenta los resultados finales de la primera fase del proyecto macro Cultura y estética popular en Boyacá, desarrollado por el grupo de investigación Xisqua. En dicha etapa se estudió el municipio de Tibasosa, por lo tanto, se presenta un análisis interpretativo de esta población desde la perspectiva de la construcción de la imagen del lugar.Para tratar el tema se realizó un estudio de corte cualitativo y enfoque fenomenológico, pues en general se indagó sobre las percepciones de los habitantes de Tibasosa. En el texto se aprecian tres categorías de análisis: la primera, los imaginarios colectivos percibidos históricamente; la segunda, la realidad recibida por los habitantes, y la tercera, las expresiones físicas que manifiestan de alguna manera ideales estéticos. A partir de ellas se llega a una serie de conclusiones que permiten identificar una imagen del municipio. éste se caracteriza, por ejemplo, por el fuerte arraigo de sus habitantes con la historia y los elementos físicos y simbólicos relacionados con tradiciones que han surgido y evolucionado hasta prevalecer en el imaginario. Tales aspectos son coherentes con las percepciones que definen a Tibasosa como de género femenino y color verde. En la población los espacios más significativos son los públicos y religiosos, y la producción de la feijoa trasciende el ámbito económico para configurarse como un elemento distintivo, real y percibido de la imagen del lugar.

Authors: Bakhsh Ebtisam A , Alkhathami Reem A , Mukaddam Shazia , Alarfaj Ohoud 
Published: August 2017

Background:
Antiphospholipid syndrome is a prothrombotic state characterized by the existence of persistent antiphospholipid antibodies. The key sequence of events is focal microthrombosis and post-infarction hemorrhage in the adrenal glands. Use of anticoagulant therapy is often used as a prevention and treatment among patients.

Case presentation:
We describe a case of 40 year old female who visited Emergency Room with complain of severe right upper quadrant pain for two days associated with nausea and vomiting. Initial laboratory investigations of blood, liver, and renal functions were normal. CT scan of abdomen revealed diffused enlargement of the right adrenal gland and showed relatively less enhancement indicating hemorrhage at the right side which later developed bilateral during admission. A day after admission, platelet count was 60,000 accompanied with worsened abdominal pain lead to diagnosis of catastrophic Anti-phospholipid syndrome (APLS).

Conclusion:
APS may lead to a variety of clinical manifestations due to venous and/or arterial thrombosis, so prescribing novel anticoagulants for patients with the APS is selective, and multiple factors are needed to be considered for a successful treatment.

Optic neuropathy after anterior communicating artery aneurysm clipping: 3 cases and techniques to address a correctable pitfall
Authors: Linzey Joseph R. , Chen Kevin S. , Savastano Luis , Thompson B. Gregory , Pandey Aditya S. 
Published: August 2017

Brain shifts following microsurgical clip ligation of anterior communicating artery (ACoA) aneurysms can lead to mechanical compression of the optic nerve by the clip. Recognition of this condition and early repositioning of clips can lead to reversal of vision loss.The authors identified 3 patients with an afferent pupillary defect following microsurgical clipping of ACoA aneurysms. Different treatment options were used for each patient. All patients underwent reexploration, and the aneurysm clips were repositioned to prevent clip-related compression of the optic nerve. Near-complete restoration of vision was achieved at the last clinic follow-up visit in all 3 patients.Clip ligation of ACoA aneurysms has the potential to cause clip-related compression of the optic nerve. Postoperative visual examination is of utmost importance, and if any changes are discovered, reexploration should be considered as repositioning of the clips may lead to resolution of visual deterioration.

OBJECTIVEThe price of coils used for intracranial aneurysm embolization has continued to rise despite an increase in competition in the marketplace. Coils on the US market range in list price from $500 to $3000. The purpose of this study was to investigate potential cost savings with the use of a price capitation model.METHODSThe authors built a clinical decision analytical tree and compared their institution’s current expenditure on endovascular coils to the costs if a capped-price model were implemented. They retrospectively reviewed coil and cost data for 148 patients who underwent coil embolization from January 2015 through September 2016. Data on the length and number of coils used in all patients were collected and analyzed. The probabilities of a treated aneurysm being ≤/> 10 mm in maximum dimension, the total number of coils used for a case being ≤/> 5, and the total length of coils used for a case being ≤/> 50 cm were calculated, as was the mean cost of the currently used coils for all possible combinations of events with these probabilities. Using the same probabilities, the authors calculated the expected value of the capped-price strategy in comparison with the current one. They also conducted multiple 1-way sensitivity analyses by applying plausible ranges to the probabilities and cost variables. The robustness of the results was confirmed by applying individual distributions to all studied variables and conducting probabilistic sensitivity analysis.RESULTSNinety-five (64%) of 148 patients presented with a rupture, and 53 (36%) were treated on an elective basis. The mean aneurysm size was 6.7 mm. A total of 1061 coils were used from a total of 4 different providers. Companies A (72%) and B (16%) accounted for the major share of coil consumption. The mean number of coils per case was 7.3. The mean cost per case (for all coils) was $10,434. The median total length of coils used, for all coils, was 42 cm. The calculated probability of treating an aneurysm less than 10 mm in maximum dimension was 0.83, for using 5 coils or fewer per case it was 0.42, and for coil length of 50 cm or less it was 0.89. The expected cost per case with the capped policy was calculated to be $4000, a cost savings of $6564 in comparison with using the price of Company A. Multiple 1-way sensitivity analyses revealed that the capped policy was cost saving if its cost was less than $10,500. In probabilistic sensitivity analyses, the lowest cost difference between current and capped policies was $2750.CONCLUSIONSIn comparison with the cost of coils from the authors’ current provider, their decision model and probabilistic sensitivity analysis predicted a minimum $407,000 to a maximum $1,799,976 cost savings in 148 cases by adapting the capped-price policy for coils.

Premise of the study:Microsatellite markers were developed for Arthropodium cirratum (Asparagaceae) to study population genetic structure and translocation of this species. These markers were tested for cross‐amplification in two other Arthropodium species.Methods and Results:Sixteen microsatellite markers were developed from a genomic library and tested in three populations of A. cirratum. The loci exhibited one to five alleles per locus, with private alleles present in each of the populations. Cross‐amplification tests in the two other New Zealand Arthropodium species revealed that many of the loci amplify and demonstrate polymorphism in A. bifurcatum.Conclusions:These markers will be useful for determining genetic structure in A. cirratum and for determining the origins of translocated populations of this species.
