The Association Between Passing Return-to-Sport Criteria and Second Anterior Cruciate Ligament Injury Risk: A Systematic Review With Meta-analysis
Authors: Losciale Justin M. , Zdeb Rachael M. , Ledbetter Leila , Reiman Michael P. , Sell Timothy C.
Published: December 2018

Background

There is no consensus on the components of return-to-sport (RTS) testing following anterior cruciate ligament (ACL) reconstruction or whether passing RTS criteria can reduce a patient's risk of reinjury.

Objectives

To determine whether impartial, criteria-based RTS decisions are associated with less risk of a second ACL injury (either graft failure or contralateral ACL injury).

Methods

In this systematic review with meta-analysis, the authors conducted an electronic literature search in PubMed/MEDLINE, Embase, CINAHL, SPORTDiscus, and ProQuest Dissertations and Theses Global using database-specific vocabulary related to ACL reconstruction and return to sport. Individual study quality was assessed using the modified Downs and Black checklist, and overall quality of evidence was determined with the Grading of Recommendations Assessment, Development and Evaluation scale. Pooled risk difference (passed versus failed RTS criteria), injury incidence proportion, and the diagnostic accuracy of each RTS criterion were calculated.

Results

Four studies met the selection criteria. Overall, 42.7% (95% confidence interval [CI]: 18%, 69%) of patients passed RTS criteria, and 14.4% (95% CI: 8%, 21%) of those who passed experienced a second ACL injury (graft rupture or contralateral ACL injury). There was a nonsignificant 3% reduced risk of a second ACL injury after passing RTS criteria (risk difference, −3%; 95% CI: −16%, 10%; I2 = 74%, P = .610). The evidence rating of the Grading of Recommendations Assessment, Development and Evaluation scale was “very low quality,” due to imprecision and heterogeneity of the pooled risk difference estimate.

Conclusion

Passing RTS criteria did not show a statistically significant association with risk of a second ACL injury. The quality-of-evidence rating prevents a definitive conclusion on this question and indicates an opportunity for future research.

The Effects of Needling Therapies on Muscle Force Production: A Systematic Review and Meta-analysis
Authors: Mansfield Cody J. , Vanetten Lucas , Willy Richard , di Stasi Stephanie , Magnussen Robert , Briggs Matthew
Published: December 2018

Background

Needling has been shown to decrease pain in the short term; however, its effects on muscle force production are unclear.

Objective

To evaluate the evidence regarding the comparative effects of needling on muscle force production.

Methods

In this systematic review, an electronic search was performed using key words related to needling. Methodological quality of articles was appraised and effect sizes were calculated. The strength of evidence was determined, and meta-analysis was performed when similar methods were used in studies for similar conditions.

Results

Twenty-one studies were included in this review, of which 9 were deemed to be of high quality (greater than 6/10 on the Physiotherapy Evidence Database [PEDro] scale), 11 of fair quality (5 to 6/10), and 1 of poor quality (less than 5/10). Three meta-analyses were performed. There was moderate strength of evidence and medium effect sizes for needling therapy to enhance force production in those with neck pain, and very low strength of evidence of no effect for individuals with nonspecific and postoperative shoulder pain and those with lateral epicondylalgia. Other studies not included in the 3 meta-analyses demonstrated no significant effect of needling on force production. These studies included individuals with carpal tunnel syndrome, knee osteoarthritis, ankle sprains, knee arthroscopy, or delayed-onset muscle soreness.

Conclusion

The majority of studies suggest no effect of dry needling on force production. High-quality studies with adequate power that control for the placebo effect and follow accepted reporting standards could make valuable contributions to the literature. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO, CRD42017080318).

Influence of Aging on Lower Extremity Sagittal Plane Variability During 5 Essential Subphases of Stance in Male Recreational Runners
Authors: Morgan Jacqueline , Kwon Yong Ung , Williams D.S. Blaise
Published: December 2018

Background

Interjoint coordination variability is a measure of the ability of the human system to regulate multiple movement strategies. Normal aging may reduce variability, resulting in a less adaptive system. Additionally, when older runners are asked to run at speeds greater than preferred, this added constraint may place older runners at greater risk for injury.

Objectives

To examine the influence of normal aging on coordination variability across 5 distinct subphases of stance in runners during preferred and fixed speeds.

Methods

Twelve older (60 years of age or older) and 12 younger (30 years of age or younger) male recreational runners volunteered for this cross-sectional study. Three-dimensional gait analyses were collected at preferred and fixed speeds. Stance phase was divided into 5 subphases: (SP1) loading response, (SP2) peak braking, (SP3) peak compression, (SP4) midstance, and (SP5) peak propulsion. Continuous relative phase variability for sagittal plane joint pairs—hip-knee, knee-ankle, and hip-ankle—was calculated. Repeated-measures linear mixed models were employed to compare variability for each joint pair.

Results

An age-by-stance subphase interaction was found for knee-ankle (P<.01) and hip-ankle (P<.01) pairs, while main effects for age and stance subphase were found for the hip-knee pair (P<.05). Specifically, loading response and peak braking variability were lower in older runners and greater across stance for knee-ankle and hip-ankle pairs, while midstance was lowest in the hip-knee pair for older and younger runners. No effects for running pace were found.

Conclusion

Less adaptive movement strategies seen in older runners may partially contribute to the increased eccentric stresses during periods of high load. J Orthop Sports Phys Ther 2019;49(3):171–179. Epub 30 Nov 2018. doi:10.2519/jospt.2019.8419
Accuracy of Clinical and Imaging Tests for the Diagnosis of Hip Dysplasia and Instability: A Systematic Review
Authors: Reiman Michael P. , Décary Simon , Mathew Benoy , Reiman Carly K.
Published: December 2018

Background

Evidence concerning the accurate clinical or imaging methods to diagnose hip instability or hip dysplasia is currently scarce.

Objective

To summarize the diagnostic accuracy of clinical and imaging tests for the diagnosis of hip dysplasia and instability.

Methods

A computer-assisted literature search of the MEDLINE, CINAHL, and Embase databases, using key words related to diagnostic accuracy of the hip joint, was conducted on March 6, 2018. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for the searching and reporting phases of the study. Quality assessment of bias and applicability was conducted using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. Diagnostic accuracy, including sensitivity, specificity, likelihood ratio, and 95% confidence interval, was summarized.

Results

Out of 3109 citations, 7 articles were included. Two studies reported on 5 clinical tests for hip instability and 5 studies reported on 5 radiographic measures for hip dysplasia. Only 1 study was not of low methodological quality. The prone instability test moderately improved positive posttest probability by 38% to diagnose hip instability. The Shenton line moderately to highly improved posttest probability by 41% to 60% to diagnose hip dysplasia.

Conclusion

This systematic review summarizes the diagnostic accuracy of various clinical tests and radiographic measures for hip instability and hip dysplasia. Further high-quality studies are necessary to examine the diagnostic accuracy of the clinical examination and radiography to assist in ruling in or ruling out the diagnoses of hip dysplasia and instability. Consensus is required to standardize the definitions of these diagnoses and their reference standards. The study was registered with the International Prospective Register of Systematic Reviews (CRD42018089019).

Authors: Hanafi Hanafi , Suryana Nanna , Basari Abdul Samad Hasan
Published: December 2018

Several efforts have been conducted to handle sparse product rating in e-commerce recommender system. One of them is the inclusion of texts such as product review, abstract, product description, and synopsis. Later, it converted to become rating value. Previous researches have tried to extract these texts based on bag of word and word order. However, this approach was given misunderstanding of text description of products. This research proposes a novel Dynamic Convolutional Neural Network (DCNN) to improve meaning accuracy of product review on a collaborative filtering recommender system. DCNN was used to eliminate item sparse data on text product review while the accuracy level was measured by Root Mean Squared Error (RMSE). The result shows that DCNN has outperformed the other previous methods.

Biofilm formation by Staphylococcus aureus Isolation from atopic Dermatitis Patients on Defined Lewis Types saliva
Authors: Abdul Fatima Rammadan
Published: December 2018

Bacteria adherence and biofilm formation vary depending on the strain of microorganism as well as the substrate.Here, we evaluated the ability of different isolates of Staphylococcus aureus (S. aureus), isolated. from atopic dermatitis patients skin and stool to form a biofilm on different Lewis types saliva, including Le (a) , (b) ,(c) and Le a+b+ saliva. S. aureus isolates were cultured on tryptose soy broth.The bacteria were used to form a biofilm on 96- well flat bottom Microtitration plate that was coated with the respective, optimally diluted, processed saliva of Lewis blood groups (a),(b),(c) and Le a+b+.The intensity of biofilm formation was assessed by measuring the biofilm-associated optical density reading of bacterial bound dye. The results indicated a superior ability of biofilm formation on Lewis(a) saliva type.The highest binding gave a mean of 1.25 ± 0.39 compared to biofilm formation on non – coated wells that showed a mean of 0.23 ± 0.016(P=0.01, CL= 0.390 – 1.635). On the other hand, however, a variable degree of binding to Le(b) saliva was demonstrated for the isolates. The isolates didn’t demonstrate binding on Lea-b-(Lec) and Le a+b+ -(Led) saliva.

 We conclude that biofilm formation on Lewis types saliva of the atopic dermatitis bacterial isolates requires Le(a) in a ligand – receptor-based system for biofilm establishment.

Energy Threshold-based Cluster Head Rotation for Routing Protocol in Wireless Sensor Networks
Authors: Ali Hadi Raheem , Lafta Hussein Attia
Published: December 2018

Energy efficiency represents a fundamental issue in WSNs, since the network lifetime period entirely depends on the energy of sensor nodes, which are usually battery-operated. In this article, an unequal clustering-based routing protocol has been suggested, where parameters of energy, distance, and density are involved in the cluster head election. Besides, the sizes of clusters are unequal according to distance, energy, and density. Furthermore, the cluster heads are not changed every round unless the residual energy reaches a specific threshold of energy. The outcomes of the conducted simulation confirmed that the performance of the suggested protocol achieves improvement in energy efficiency.

Because the big grown of the digital market and the growing demand for protection to data and information which transmitted through the Internet. Steganography is the art of embedding, hiding information into different digital media, it was the main reason to increase its importance in the exponential development of the secret communication of computer and digital cloud users over the internet. There are a lot of techniques and different ways to achieve hiding data. Usually, the data embedding is obtained in communication such as image, text, voice or any multimedia content for copyright and also in military communication for authentication and many other different purposes. In this paper, we protected the information in two ways: Encryption and Steganography. The basic idea is to present a method that encrypted the message firstly by using The AES (Advanced Encryption Standard) it is a symmetric-key encryption each of these ciphers it has 128-bit the size to block, and size keys of 128, 192 and 256 bits.  Secondly, hide that encrypted message in color cover image in the Least Significant Bit (LSB) to image’s frame with (.bmp, .jpg) extensions. Our scheme is to enhance the ability of LSB algorithm to include the storage of information and images encoded and intangible sense of human vision. That two methods to increased together the security attend any attack.

La diversidad de los maíces nativos representada por presencia de razas primarias per se, mezclas genéticas entre ellas, la pluralidad de agroecosistemas donde se cultivan y las interrelaciones entre ellos; propician la presencia de patrones etnogenéticos o varietales. La presencia de maíces nativos en el Estado de Nayarit en la actualidad puede ser considerada amplia, en virtud de que se encuentran en la totalidad de los municipios. El objetivo del presente trabajo fue conocer y destacar la importancia de las Razas Tabloncillo y Tuxpeño como patrones raciales etnogenéticos determinantes en la conservación genética de los maíces nativos de Nayarit. De 2008 a 2012 se realizaron 166 colectas, las cuales fueron caracterizadas agronómicamente y determinada su clasificación racial. Variables de planta (mazorca y grano) y ambiente en función de su georreferenciación fueron consideradas. Las características de longitud de mazorca, granos por hilera, ancho y longitud de grano permitieron identificar fenotípicamente al patrón etnogenético de Tabloncillo, y las características de diámetro de mazorca, número de hileras, grosor de grano y volumen de grano al Tuxpeño. Las variables ambientales permitieron corroborar la distribución de ambos corredores etnogenéticos y la ubicación de sus respectivos nichos ecológicos.

Debido que México se encuentra inmerso en una economía mundial que cambia constantemente, es de vital importancia medir los efectos de la política agrícola mediante el uso de los recursos con los que cuenta el erario público. Dentro de este contexto, parte de los recursos que el productor recibe como subsidios son a través de PROCAMPO. El objetivo general, consistió en determinar sí la producción y el consumo (entre otras variables), tienen una relación de interdependencia de PROCAMPO en el momento en que el productor decide participar o no en el programa; es decir, ¿Estás variables condicionan las decisiones del productor respecto de PROCAMPO? y ¿En qué medida? En este sentido, la metodología a seguir fue por medio de la utilización del modelo logit, donde los resultados obtenidos; a través, de esta prueba de variable dependiente cualitativa, mostró que la probabilidad de que un productor del municipio de Villaflores, Chiapas, se incorpore a PROCAMPO, aumenta 55%; sin embargo, la probabilidad de que un productor se incorpore al mismo programa, incrementa 91% cuando este cultive maíz. Se concluye que las variables independientes de producción y consumo condicionan las decisiones del productor agrícola respecto de PROCAMPO, en el área de estudio.

The cost of electromechanical equipment in a small hydro power storage plant
Authors: ALZOHBİ Gaydaa
Published: December 2018

Pumped
hydroelectric storage (PHS) is the most established technology for
utility-scale electricity storage. To take investment decision for the
development of small hydropower projects, technical feasibility and financial
viability are considered to be the foremost requirements. The
cost of electro-mechanical equipment means a high percentage of a small
hydro-power plant budget (around 30 % and 40 % of the total sum). It seems from
this importance of the determination of that cost, which could directly
influence the project feasibility. An overview of existing methods to estimate
the cost of hydro turbines is presented in this paper. Empirical formulas to
estimate the cost of centrifugal pump for a power ≤ 2 MW and PAT (pump as
turbine) for a power ≤ 550 kW. In addition, new correlations have been
developed to estimate the cost of hydraulic turbines (Pelton, Kaplan, Francis
and Francis reversible) for a power > 2 MW were developed through
statistical analysis of cost data obtained from pumps and hydraulic turbines
manufactures. The
cost of EM equipment increases for high power levels but it decreases for high
head.

This comparison study focuses on the impacts of using nano-silica (nS) on chemical attack resistance of self-consolidating concrete (SCC) and its effectiveness in comparison to similar replacement levels of the more widely employed micro-silica (mS). Two types of cement were used to produce concrete mixes and three different percentages (3, 4.5, and 6 %) of nanosilica and microsilica were added as a replacement of cement by weight. Concrete specimens were cast and exposed to four harmful conditions including: sulfate solution, chloride solution and both of them for a period of up to 400 days. Based on the obtained results, replacement with colloidal nS proved to be significantly more effective in the chemical resistance than equivalent replacement of dry powder mS. The noticed improvements in chloride resistance and chloride penetration performance for concretes contained nS was correlated with the compressive strength results, which indicates for better pore structure characteristics. As expected, the improvement in the chemical resistance was more pronounced in concretes with cement type V.

Finding a vacant parking space nowadays is time and fuel consuming. This problem may cause drivers to get frustrated and eventually improper parking will appear. The universities, in particular, are one of these places, which needs more attention for providing parking services. Therefore, this study has focused on finding the parking required for such facilities and the benefit of applying smart parking services there. The main campus of the University of Kufa has been evaluated by collecting parking data for both on-street and off-street parking. The results of field data show a clear lack of parking space for most of the faculties in the main campus. The required additional parking spaces are 260.This study has suggested using the smart parks. The model of smart park system has been introduced by this study as a solution to the parking problem, especially in the university and generally in other places. Arduino and ultrasonic sensors were used to detect the empty places in a park and display this status to the screen. The model has been applied at the park of College of Engineering with encouraging results.

Published: December 2018

This paper discussed the effect of welding variables on the heat-affected zone (HAZ) by using a tensile test of welded 10 mm thick low carbon steel AISI1010 commercial plate, which is welded using the Shielded Metal Arc Welding (SMAW) method. Different welding electrodes E6013 and E7018 were considered as welding parameters investigated. After that, the welded specimens were cut and machined to standard configurations for tensile test. The results showed that selecting different welding electrodes had a remarkable effect on the mechanical properties such as the ultimate tensile strength, elongation percentage, and yield strength of the welded specimens. The increment in the electrical current for each electrode in the welding processes led to decrease in yield strength and tensile strength. The initial decrease in tensile strength and yield strengths were observed. This behavior was attributed to the fact that different welding electrodes and increased the required electrical current to melting for the welding electrode, increased the electrical current led to increased heat input on heat affected zone (HAZ), then the observed change mechanical properties [which could create area for defect. The welding processes and tensile test at a room temperature was performed

Published: December 2018

Geopolymer concrete is still a new construction material in Iraq and needs tremendous research to get more information about the production technique. In this study, the foreign fly ash and local fly ash produced from Baghdad south gas power plant were used with good specifications to obtain geopolymer concrete. Also, the local attapulgite clay as a pozzolan material is used to investigate the possibility for production the geopolymer concrete. The experimental results showed that the method of curing of geopolymer concrete has a significant effect on the development of compressive strength. Water immersion curing is not recommended. The heat treatment method is the best due to accelerating the reactions and formation of geopolymer concrete. The attapulgite is the best suited locally for geopolymerization in terms of compressive strength and tensile strength.

Fine aggregate considered as the oldest building materials known by human, it's not inert substance, so that each of its physical and chemical properties need theoretical and laboratory studies, because, of its effect on the compressive strength and durability of concrete, one of the most important properties is the content of sulphate salts, which must be taken into account in all construction works. This research aims to conduct laboratory qualitative assessment of fine aggregate to demonstrate its suitability for construction work and quality assurance. Sampling of fine aggregate (sand) from four quarries in Al-Najaf Alashraf [(Syd Ali (S1), Wilaya Ali (S2), Syd Ahmed (S3) and Muhand Al-Khiat (S4)]. Some of physical tests (sieve analysis, deleterious materials (clay%), bulk density, specific gravity and absorption), chemical analysis for sulphate salts content, X-Ray technology for mineral composition as well as the compressive strength test were conducted on these samples. From the results of this research, its appear that Sample Wilaya Ali (S2) is the best for concrete works where the grading and sulphate salts content (SO3) is accepted by (IQS), and this sample gives accepted compressive strength. While Sample Syd Ali (S1) was the most fine with accepted sulphate salts content as compared with (IQS) which make it suitable for other construction works rather than concrete. Samples, Syd Ahmed (S3) and Muhand Al-Khiat (S4) are of high sulphate salts content (which cannot be treated) as compared with (IQS) which make them not compatible for concrete and other construction works.

Authors: Anssari Othman
Published: December 2018

At the high power switching circuit's applications, when the harmonic distortion is harmful, a multi-level diode clamped inverter is useful, especially when reduced total harmonic distortion and high power are desired. But when the levels get a rise, number of semiconductors are also rising, which leads to many problems such as increasing cost, losses, installation area, and total harmonic distortion. Many researchers have tried to find solutions to these problems. In this sense, this paper focuses on: a) build a new structure of five level diode clamped inverter. b) Increase the efficiency of the inverter by reducing the number of switches. c) Reduce the total harmonic distortion. The theoretical calculation and simulation results are performed for five level diode clamped inverter by MATLAB/ SIMULINK.

Authors: Hassan Ayman
Published: December 2018

Wastewater effluent of plants is frequently disposed via injection wells or drain fields into the geological substrate near surface water streams. In this study, we evaluated and specified the relationships between the plants wastewater disposal flow, concentrations, and the disposal injection wells distances from surface water stream for minimum harmful pollutants transport to the stream. The study area was Basrah fertilizes plant near Shatt-Al-Basrah stream. A completed representation for the study area parameters data were done to simulate the aquifer, surface water, pollutants disposal, and flow-transport system for the current state and the proposed injection wells systems. The simulation and evaluation study showed that the current disposal system is harmful to the stream and the best disposal system for the wastewater plant was the injection wells. The study also revealed that the best distance for the proposed fertilizes plant disposal wells must be located not less than 480 m from the river with an injection rate not more than 3600 m3/day.
APPLICATION OF ARTIFICIAL NEURAL NETWORKS TO PREDICT SOIL RECOMPRESSION INDEX AND RECOMPRESSION RATIO
Authors: Abbas J. Al-Taie Abbas J. Al-Taie , Al-Bayati Ahmed
Published: December 2018

Overconsolidated soils are widely encountered in practice where settlement calculations are crucial. The recompression index (Cr) and the recompression ratio (Cr) are considered as one of the most important parameters used in settlement calculations. To achieve this purpose, expensive and time-consuming laboratory tests are usually conducted using undisturbed specimens to obtain the values of these parameters. Various equations derived from regression analysis were proposed to predict consolidation parameters from the physical properties of a soil. In this paper, however, an artificial neural network model (ANN) is proposed to predict Cr and Cr using natural water content, initial void ratio, total unit weight and effective overburden pressure. The proposed ANN model achieved good agreement with the results of one hundred seventy-nine standard one-dimensional consolidation tests collected from previous geotechnical investigations in Baghdad.

Published: December 2018

Este trabalho tem o propósito de promover uma análise estrutural e semântica do universo sobrenatural presente no romance As horas nuas, de Lygia Fagundes Telles. Nosso estudo almeja estudar o livro à luz de teorias outras que distanciam sobrenatural contemporâneo daquele tradicional pertencente aos séculos XVIII e XIX. Para isso, teremos como norte as palavras do escritor italiano Italo Calvino – em quem nos apoiaremos para promover uma leitura mais atual desse universo metafísico − assim como a teoria do argentino Jayme Alazraki – estudioso responsável pela criação do termo neofantástico, palavra com que define essa forma derivada da antiga narrativa fantástica, aquela tão amplamente teorizada por Tzvetan Todorov.
