Pediatric acute paradoxical cerebral embolism with pulmonary embolism caused by extremely small patent foramen ovale
Authors: Yamaguchi Junko , Noda Akihiro , Utagawa Akira , Sakurai Atsushi , Kinoshita Kosaku
Published: January 2019

Herein, we report a pediatric case of acute paradoxical cerebral embolism complicated by serious acute pulmonary embolism that was caused by an extremely small patent foramen ovale (PFO). The patient had no medical history suggestive of any other reason.

Paradoxical cerebral embolism may occur even with an extremely small PFO because of the increased right-side pressure of the heart and a resulting right-to-left shunt from the acute pulmonary embolism. Although pediatric cases of pulmonary embolism are rare, when diagnosed, clinicians should consider the risk of a concurrent paradoxical cerebral embolism resulting from a latent PFO. The possibility of PFO should be assessed extremely carefully in pediatric critical care by checking for a thrombogenesis tendency and the existence of deep vein thrombosis in the patient.
Associations between ambient temperature and acute myocardial infarction
Authors: Zhao Hong-Ying , Cheng Jing-Min
Published: January 2019

Background

The associations between incidence of acute myocardial infarction (AMI) and the ambient temperature were mixed in prior studies.

Methods

Data of 2033 consecutive admissions of AMI in a central tertiary hospital in North China from 1st Jan 2003 to 31st Dec 2011 were collected. The weather data in this period were from the local meteorological department. Based on the ambient temperature information, we defined several ambient temperature indices, including daily average temperature, extremely low temperature, and daily temperature range, then characterized the independent associations between them and the incidence of AMI.

Results

The daily average temperature one day before was independently associated with AMI incidence rate: a rise of 5°C of the daily average temperature led to a 5% decrease in AMI admissions. Daily average temperature and temperature range two days before were independently associated with AMI incidence rate: a rise of 5°C of the daily average temperature led to a fall of 6% in AMI admissions, and a rise of 2°C of the daily temperature range led to a rise of 4% in AMI admission.

Conclusion

Low ambient temperature has substantial association with AMI, and can play an important role in warning and forecasting the incidence.
Penetrative convection in a fluid saturated Darcy-Brinkman porous media with LTNE via internal heat source
Authors: Mahajan Amit , Nandal Reena
Published: January 2019

The present work involves the study of penetrative convection in an incompressible fluid-saturated porous media with local thermal non-equilibrium. The onset of convection evaluated linearly and nonlinearly for the system influenced by heat extraction and heat generation. Darcy-Brinkman law is employed to model the momentum equation and four type of internal heat generating function are considered which leads to thermo-convective instability within the fluid layer. Linear analysis carried out by using normal mode technique and nonlinear stability analysis has been done by energy method. Due to heat generation within the fluid layer and heat extraction through boundary, the subcritical instability may exist with higher possibility. Effects of various parameters as: inter-phase heat transfer parameter, Darcy-Brinkman number, porosity-modified conductivity ratio, and heat parameter are explored on Darcy-Rayleigh number by Chebyshev pseudospectral method as numerical form and graphical form.

Model of Implementation of Juvenile Criminal System to the Criminal Offender (Educative Perspective on Institute for Special Development Children LPKA Kutoarjo, Central Java, Indonesia)
Authors: Arifin Mokhammad Dony
Published: January 2019

The Kutoarjo Class I Special Guidance Institute Purworejo Regency, Central Java, the author chose as a research locus, because he wanted to see the extent of Article 1 paragraph 2 of Law Number 12 of 1995 implemented. The formulation of the problem in this study as follow: (1) how is the implementation of juvenile crime on criminal offenders in an educative perspective at the Kutoarjo Class I Special Guidance Institute Purworejo District, Central Java? (2) What is the model of the implementation of child crime on criminal offenders in an educative perspective at the Kutoarjo Class I Special Guidance Institute Purworejo District, Central Java? This study aims to: (1) Describe the implementation of juvenile crime on criminal offenders in an educative perspective at the Kutoarjo Class I Special Training Institute Purworejo District, Central Java. (2) Finding a model of the implementation of juvenile crime on criminal offenders in an educative perspective at the Kutoarjo Class I Special Guidance Institution in Purworejo District, Central Java. The results of research on the implementation of juvenile crime on criminal offenders in an educative perspective at the Kutoarjo First Class Special Guidance Institution in Purworejo Regency, Central Java have not been fully and consistently implemented. This is evidenced by the inconsistencies in the schedule for the existing children facing the law (Anak Berhadapan dengan Hukum, ABH). It is also proven by the lack of competent educators in their respective fields. With the formation that is still theoretical, it can be guaranteed that the ABH will not be able to become a new person who is confident later, because it will be continuously shadowed about jugde as a prisoner. This mindset that must be changed from now on, with various kinds of learning using the Islamic boarding school model that is taught and instilled since in prison, will bring positive impact on ABH along with its good future.
Corporate Responsibility in Money Laundering Crime (Perspective Criminal Law Policy in Crime of Corruption in Indonesia)
Authors: Wibowo Muhtar Hadi
Published: January 2019

Money laundering is a stand-alone crime, although money laundering is born from its original crime, such as corruption, but the anti-money laundering regime in almost all countries places money laundering as a crime independent of its original crime in the case of a money laundering probe. The purpose of this study is to describe and analyze criminal law policies in regulating corporate accountability for current money laundering, analyze the implementation in law enforcement against corporations engaging in money laundering, and establish a model of criminal law policy on corporate liability that commits a crime money laundering in the future. This research emphasized that criminal law policy in ordering corporate responsibility to money laundering crime has been regulated in Money Laundering Criminal Act. The Money Laundering Act in Indonesia has indeed accepted corporations as a subject of criminal law, there are several cases that indicate the involvement of corporations engaging in money laundering practices in Indonesia but at the stage of settlement within the justice system there is not a single corporation that has been charged and sanctioned criminal. In line with the development of specific laws, corporations are categorized as subjects of criminal law.

Genetic Effects on Dispersion in Urinary Albumin and Creatinine in Three House Mouse (Mus musculus) Cohorts
Authors: Perry Guy M L
Published: January 2019

Conventionally, quantitative genetics concerns the heredity of trait means, but there is growing evidence for the existence of architectures in which certain alleles cause random variance in phenotype, termed ‘phenotypic dispersion’ (PD) or ‘variance QTL’ (vQTL), including in physiological traits like disease signs. However, the structure of this phenomenon is still poorly known. PD for urinary albumin (PDUAlb) and creatinine (PDUCrea) was mapped using curated data from two nearly genetically identical F2 mouse (Mus musculus) cohorts (383 male F2 C57BL/6J×A/J (97 SNP) and 207 male F2 C57BL/6J×A/J ApoE knockout mice (144 SNP)) and a related mapping cohort (340 male F2 DBA/2J×C57BL/6J (83 SNP, 8 microsatellites)). PDUAlb was associated with markers in regions of Chr 1 (5-64 megabases (MB); 141-158 MB), 3 (∼113 MB), 8 (37-68 MB), 14 (92-117 MB) and 17 (14-24 MB) with several positions and quantitative architectures in common between the two C57BL/6J×A/J cohorts, most of which had a negative dominant construction. One locus for PDUCrea was detected on Chr 19 (57 MB) in the C57BL/6J×A/J ApoE−/− cohort. The large number of negative dominant loci for albuminuria dispersion relative to conventional quantitative trait loci suggests that the development of albuminuria may be largely genetically dynamic and that randomization in this development is detrimental.
Ethical Implications for Providers Regarding Cannabis Use in Children With Autism Spectrum Disorders
Authors: Duvall Susanne W. , Lindly Olivia , Zuckerman Katharine , Msall Michael E. , Weddle Melissa
Published: January 2019

Children with autism spectrum disorder (ASD) are at risk for self-injurious behaviors that can be difficult to treat in the context of co-occurring low IQ and adaptive skills. Increased prevalence and decriminalization of cannabis in some states have led to more frequent questions for pediatricians about the use of cannabis for difficult-to-treat developmental and behavioral conditions. What do we know about the possible benefits and risks of cannabis use in children with ASD? How should the clinician respond to a parent who expresses interest in cannabis to manage behavior in a child with ASD? Ethical analysis that includes harm reduction, health concerns, and information sharing will be discussed. We present commentary on the ethical implications of cannabis use in children with ASD and severe self-harm behaviors.
Obesity and Weight Loss
Authors: Conti C Richard ,   Professor Emeritus of Medicine, Division of Cardiovascular Medicine, University of Florida, Gainesville, Florida, USA
Published: January 2019

The entire world is becoming overweight. Most people are motivated to try to lose weight for cosmetic reasons. Weight loss can decrease health risk factors and possibly improve prognosis. Weight loss can be difficult in people who are trying to stop smoking, as they tend to gain weight. Many weight loss systems are available and are not inexpensive. Athletes who are obese and fit must lose weight after retirement or suffer the consequences related to risk factors. Bariatric surgery seems to be the best way for morbidly obese patients to lose weight, assuming that they adhere to principles of risk factor modulation. Weight-loss medications work in most patients who also comply with lifestyle changes, but these drugs have a number of side-effects.

Published: January 2019

Despite high mortality, cardiovascular disease (CVD) is underestimated in autoimmune rheumatic diseases (ARDs), due to its atypical presentation. The multi-faceted nature of CVD in ARDs created the need of a dedicated outpatient cardio-rheumatic clinic. Clinical examination, rest/exercise ECG, echocardiography, nuclear techniques and cardiac catheterisation were used as first-line diagnostic tools. Although the currently used non-invasive modalities perform well in cardiology, they are unable to diagnose the complex CVD pathophysiology of ARDs. The application of cardiovascular magnetic resonance (CMR) offers some significant advantages. CMR is versatile and can be used to perform functional, stress-rest perfusion, fibrosis and evaluation of great, peripheral and coronary vessels patency, without the use of ionising radiation, allowing early diagnosis of CVD and prompting modifications of anti-rheumatic and cardiac treatment.

Authors: Pavani Harsha Praneeth , Tadepalli Tezeswi , Agrawal Ashish Kumar
Published: January 2019

Portland pozzolana cement (PPC) and ordinary Portland cement (OPC) OPC-53 grades of cement are commonly used in India. The thermal responses of these types of Portland cement (PC) differed upon analysing the compressive strengths of their hydrated cement block specimens at elevated temperatures. At 800°C, PPC was able to maintain the integrity of the cube, while OPC-53 failed to do so at 500°C. Thermal analyses were performed to interpret the performance of these two types of PC, and four critical regions of interest, – namely, 100°C, 400°C, 500°C and 800°C – were selected. X-ray diffraction and carbon hydrogen nitrogen sulfur-oxygen elemental analysis were conducted on both cements, and variations in the elemental and phase percentages were observed. The number of pores in OPC-53 was 4·51 times greater than that in PPC at 800°C. Additionally, relatively small pore radii ranging from 2·54 μm to 34·80 μm were observed for OPC-53 at 400°C; however, PPC contained pores with radii ranging from 2·54 μm to 67·23 μm. Ultimately, the development of micropores constitutes one of the primary reasons for structural collapse.
Ratio of long-term settlement to immediate settlement for piled raft on soft clay
Authors: Liu Chenhui , Yang Min , Bezuijen Adam
Published: January 2019

A simplified analytical approach based on the non-linear pile–soil interaction model under vertical load is employed to analyse settlement of piled raft foundations. The accuracy of the simplified method is verified through comparisons with the results from previous research. Furthermore, according to the calculation results of various pile configurations, a simple empirical equation for estimating long-term settlement of a piled raft foundation is proposed. The prediction equation is validated through comparison with published cases. The comparison results show that the ratio of long-term settlement to immediate settlement increases linearly with the square root of the number of piles (at the same pile spacing), whereas the influence of the length/diameter ratio of the pile is small. The settlement ratio is approximately 2 for a piled raft foundation, and 1·5 for a raft or box foundation, and this may be useful for preliminary assessment of the long-term settlement behaviour of piled raft foundations.

Bagasse is biomass residue generated on extraction of juice from sugarcane. It is commonly used as fuel for electricity generators, and its calcination produces sugarcane bagasse ash (SCBA). Finely ground SCBA can be used as partial replacement for cement. In this study, the effects of SCBA incorporating different quartz contents on properties of cement pastes and mortars were investigated. SCBA with a high carbon content retrieved from Brazilian industrial boilers was washed with water. Two ashes, namely top wash SCBA with a low quartz content and bottom wash SCBA with a high quartz content, were obtained. Both ashes were compared with the as-received control ash. The SCBA samples were recalcinated by conjugate burning and then finely ground. Results show that bottom SCBA had more crystalline phases, while top SCBA was more active, achieving a higher pozzolanic activity. Isothermal calorimetry showed that SCBA cement released increased heat of hydration due to heterogeneous nucleation and exothermic hydration reactions. Mercury intrusion porosimetry showed that SCBA contributed to refining the pore structure. Mechanical strength results indicated that SCBA can be used for partial replacement of cement, enhancing the sustainability and engineering properties of cement-based materials.

Hydrogen is an environmentally friendly alternative to conventional fossil fuels and is considered as a renewable energy carrier for meeting the ever-increasing energy demand. Although hydrogen is abundant on earth in the form of compounds such as water, producing molecular hydrogen demands a large amount of energy. A solid oxide electrolysis cell (SOEC) is an electrochemical device which generates hydrogen from various sources. An SOEC uses high temperature (>800°C) to electrolyse water with high efficiency assisted by thermodynamically favoured water splitting that enables large-scale hydrogen production. This review provides a comprehensive overview of the current status in the developments of high-temperature steam electrolysis using a proton- and oxygen-ion-conducting SOEC system for hydrogen production. The present review summarises the detailed approaches for hydrogen production using SOECs, basic principles, challenges in designing hydrogen and oxygen electrodes and electrolytes, and potential solutions to durability issues.
Moment–rotation behaviour of non-bolted planar joints for segmental tunnels
Authors: Peña Fernando , Galván Arturo , Moreno-Martínez Jatziri Y. , Herrera-Díaz Israel E.
Published: January 2019

Segmental tunnels cannot be considered as continuous rings due to the existence of joints. The mechanical behaviour of the segment joints is defined by the axial load in the joint. However, this load is not constant throughout the analysis, so it is necessary to make a series of iterations. A practical moment–rotation equation to represent the mechanical behaviour of typical planar joints without steel bolts is proposed. The advantage of the constitutive equation proposed in this paper is that the need for iteration is taken away because the eccentricity of the axial load remains constant during the loading process. This equation depends on the geometry of the joint, the elastic properties of the concrete and the eccentricity of the axial load in the joint. The equation was validated by means of (lab-based) experimental research on planar joints and was used in numerical models of single rings based on the finite-element method. It was concluded that this equation represents the mechanical behaviour of this type of joints correctly and, therefore, can be used to analyse single rings for segmental tunnels, reducing the computational effort spent in three-dimensional models.
Modelling of the flexural stiffness of concrete-steel beams under negative moment
Authors: Alkloub Amer , Allouzi Rabab
Published: January 2019

Composite concrete–steel sections are widely used in flooring and decking systems in buildings and bridges. Concrete decks form cracks at negative moment regions and remain uncracked at the positive ones. Finite-element (FE) analyses of beams composed of concrete–steel sections must take the change in the composite section properties into consideration on the basis of the level of cracks in the concrete deck. Commercial FE software packages use linear elastic analysis for calculating the moment and shear force distributions in beams loaded with gravitational loads, with no consideration of the level of cracking in the concrete slab at the negative moment regions. A FE modelling technique for beams with concrete–steel sections was developed by using FE software packages to estimate the internal loadings necessary for the design process. The results from the proposed FE technique were compared with experimental data on continuous and simply supported beams reported by other researchers. It was found that consideration of the concrete deck longitudinal reinforcement in the modelling of a composite section over negative moment regions is necessary for identifying flexural properties, resulting in better accuracy of the structural analysis outcomes. The proposed modelling technique estimated deflection in the tested beams with only 7% error with respect to the experimentally measured deflection.
Mobile device applications usability assessment: The example of an agricultural management application

Published: January 2019

This paper examines the issue of mobile application usability assessment and is primarily intended to evaluate a "proposal" concerning the systematic recording of the technical and economic data of an agricultural holding with the aid of a rural management system (agroFarm). This application is an electronic calendar where farmers and breeders can store all the agricultural activities about crops, farms and agricultural machineries. Simultaneously agroFarm calculates the revenues and expenses of every rural activity.

The use of mobile applications requires solving problems in use so that access to information and services can be done without difficulty. This is achieved by assessing the use with methods that can measure the usability of mobile applications.

The application was evaluated with, the Questionnaire for User Interaction Satisfaction questionnaire. Ten users aged 20 to 45, at least high school graduates, holding different farms and different familiarity with digital applications participated in the evaluation process. In addition, a Heuristic evaluation was performed by experts who were asked to evaluate ten "heuristics criteria" and whether they were observed in the evaluated application.

The results of the evaluation showed that the users consider that most important feature of mobile applications is the ease of use and utility.
Self-Efficacy Levels of Classroom Teachers

Published: January 2019

The purpose of this research is to determine the self-efficacy levels of classroom teachers. This research was made in the survey model. The universe of the research is composed of 2200 classroom teachers who are working in state primary schools in Elazığ in the 2017-2018 academic year. The sample consists of 269 classroom teachers determined by simple random sampling. “Teachers' Sense of Efficacy Scale" developed by Tschannen-Moran and Hoy (2001) and adapted to Turkish by Çapa, Çakıroğlu and Sarıkaya (2005) was used as the data collection tool in the research. Self-efficacy levels of classroom teachers are quite adequate in the sub-dimensions of self-efficacy for classroom management and for student participation, and in the whole scale. In the sub-dimension of self-efficacy for instructional strategies, it is higher, although it is at the same level. There was no significant difference between self-efficacy levels of classroom teachers according to gender, education level and the variables of the teachers' place of residence. Self-efficacy levels of teachers working in schools with a number of teachers between 1-10 are higher than those between 20-29. It can be said that, as the self-efficacy towards classroom management increases, the level of self-efficacy towards student participation and teaching strategies increases.
