Authors: Malleus Elina , Kikas Eve
Published: April 2019

This study describes the role of interest in eighth-grade students’ (N=183) knowledge formation. Student knowledge was measured through open-ended questions at three time points: once before and twice after specific topics had been taught in a regular 45 min geography lesson. Student interest level was assessed using teacher ratings. Student answers to seven open-ended questions were coded and placed into one of three categories: everyday, synthetic, or scientific knowledge. Results showed that higher interest was related to providing fewer everyday and more synthetic answers. However, student answers changed similarly in all interest groups as measured before and after learning. The content of student answers tended to change as a result of the lesson, but these changes reflected the formation of new synthetic knowledge.

Authors: Cho Young Sung , Jeong Seon-phil
Published: April 2019

Lately, the Critical Pathway(CP) of Electronic Medical Record(EMR) is used to the guideline for a treatment in the public hospital. We propose a healthcare promotion service using disease pattern with lifestyle risk factors. We classify a medical historical patient data with disease codes with lifestyle risk factors (hypertension, diabetes, smoking, overweight, excessive alcohol intake, and low physical activity) to make the lifestyle risk factors through the classification. We finally make the clusters of disease code with lifestyle risk factors using the medical historical data based on EMR's electronic discharge summary data. As the result of that, we do a healthcare recommending service based on the disease pattern with lifestyle risk. We can build a medical help desk of a public hospital to support people as we check into the public hospital; how to get the procedure of curing, the desired curing clinical method for the healthcare promotion service by each disease code, and how to be better our healthcare. We evaluate the performance of the proposed system by experimenting with the datasets collected at the medical center to measure performance and report some experimental results.
The Dehydrogenation Mechanism and Reversibility of LiBH4 Doped by Active Al* Derived from AlH3
Authors: He Qing , Zhu Dongdong , Wu Xiaocheng , Dong Duo , Jiang Xiaoying , Xu Meng
Published: April 2019

A detailed analysis of the dehydrogenation mechanism and reversibility of LiBH4 doped by active Al* derived from AlH3 was performed by thermogravimetry (TG), differential scanning calorimetry (DSC), mass spectral analysis (MS), powder X-ray diffraction (XRD), scanning electronic microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The results show that the dehydrogenation of LiBH4/Al* is a five-step reaction: (1) LiBH4 + Al → LiH + AlB2 + “Li-Al-B-H” + B2H6 + H2; (2) the decomposition of "Li-Al-B-H" compounds liberating H2; (3) 2LiBH4 + Al → 2LiH + AlB2 + 3H2; (4) LiBH4 → LiH + B + 3/2H2; (5) LiH + Al → LiAl + 1/2H2. And the reversibility of LiBH4/Al* composite is based on equation as follows: LiH + LiAl + AlB2 + 7/2H2 ↔ 2LiBH4 + 2Al. The extent of dehydrogenation reaction between LiBH4 and Al* greatly depends on the precipitation and growth of reaction products (LiH, AlB2 and LiAl, etc.) on the surface of Al*. A passivation shell of Al* formed by these products is the kinetic barrier to the dehydrogenation of LiBH4/Al* composite.

Published: April 2019

Intelligent mobile robots need self-localization, map generation, and the ability to explore unknown environments autonomously. Probabilistic processing can be applied to overcome the problems of movement uncertainties and measurement errors. Probabilistic robotics and simultaneous localization and mapping (SLAM) technologies are therefore strongly related, and they have been the focus of many studies. As more and more practical applications are found for intelligent mobile robots, such as for autonomous driving and cleaning, the applicability of these techniques has been increasing.

In this special issue, we provide a wide variety of very interesting papers ranging from studies and developments in applied SLAM technologies to fundamental theories for SLAM. There are five academic papers, one each on the following topics: first visit navigation, controls for following rescue clues, indoor localization using magnetic field maps, a new solution for self-localization using downhill simplex method, and object detection for long-term map management through image-based learning. In addition, in the next number, there will be a review paper by Tsukuba University’s Prof. Tsubouchi, who is famous for the Tsukuba Challenge and research related to mobile robotics.

We editors hope this special issue will help readers to develop mobile robots and use SLAM technologies and probabilistic approaches to produce successful applications.

This study proposes an indoor self-localization for the estimation of the position and posture of an instrument using multiple magnetic sensors. First, a magnetic map for the localization is efficiently created using multiple sensors and a local positioning device made from an optical sensor and a gyroscope. For the localization estimating trajectories, the measurement error of the local positioning is corrected by matching it with the magnetic map. Our instrument is composed of six magnetic sensors, and the description of the self-localization details is based on the framework of a particle filter. The experimental results show better indoor path trajectories compared with a raw trajectory without map matching. The accuracy of the instrument using various numbers of magnetic sensors for the estimation is also investigated.

Published: April 2019

Image change detection is a fundamental problem for robotic map maintenance and long-term map learning. Local feature-based image comparison is one of the most basic schemes for addressing this problem. However, the local-feature approach encounters difficulties when the query and reference images involve different domains (e.g., time of the day, weather, season). In this paper, we address the local-feature approach from the novel perspective of object-level region features. This study is inspired by the recent success of object-level region features in cross-domain visual place recognition (CD-VPR). Unlike the previous contributions of the CD-VPR task, in the cross-domain change detection (CD-CD) tasks, we consider matching a small part (i.e., the change) of the scene and not the entire image, which is considerably more demanding. To address this issue, we explore the use of two independent object proposal techniques: supervised object proposal (e.g., YOLO) and unsupervised object proposal (e.g., BING). We combine these techniques and compute appearance features of their arbitrarily shaped objects by aggregating local features from a deep convolutional neural network (DCN). Experiments using a publicly available cross-season NCLT dataset validate the efficacy of the proposed approach.
Co-Production to Overcome Water Influx in Alaskan Reservoir

Published: April 2019

The Sterling B4 sands is a reservoir underlain by an aquifer located on the Kenai Peninsula of Alaska. This dry gas-on-water reservoir, holding approximately 13.9 billion cubic feet (Bcf), has experienced challenges since its first development in the 1960s. The gas-water contact is very mobile and easily influenced upward by gas production. All four wells, largely producing in succession of one another, have experienced excessive water production which killed gas production. Faulty drilling and completion work exacerbated the challenges associated with bringing the gas to market.

This paper summarizes an effort to model the Sterling B4 development and determine feasible alternatives for revival of the reservoir and commercialization of the produced gas. Those alternatives include infill drilling, variable production, and co-production. Co-production is a method by which gas is produced from the gas zone and water is produced from the water zone; each stream is produced independently by either mechanical means or different wells.

The only feasible alternative found in this study is co-production. Of the two co-production methods analyzed, the highest ultimate recovery includes the utilization of an existing vertical well perforating the upper portion of the reservoir for gas production and a new lower horizontal well perforating the water zone to control the gas-water contact. Modeled production schemes proved the gas-water contact may be controlled from upward mobility by maintaining a threshold pressure difference between the bottom-hole pressures of the two producing wells. Utilizing co-production in this manner yielded incremental benefit of over 2 Bcf until shut-in limits were triggered, achieving an ultimate recovery of up to 43%.

Economic analysis of the project has proved bringing the gas to market presents a significant prize able to support production and full facility operational expense despite no other revenue streams. Should other nearby formations demonstrate sufficient targets, the economic case would be enhanced and present an even greater prize.
How Big Data Analytics Can Help Future Regulatory Issues in Carbon Capture and Sequestration CCS Projects
Authors: Balaji Karthik , Zhou Zifu , Rabiei Minou
Published: April 2019

In this age of data, there is a significant need for tracking and prediction of non-compliance of rules & regulations in various industries including the oil & gas sector. In this paper, we will be reviewing some of the anticipated regulatory issues in commercial implementations of carbon capture & sequestration (CCS) and discuss how machine learning and big data analytics can diminish future non-compliance incidents.

With the rising awareness of advanced data-driven technologies such as "Big Data Analytics" and "Machine Learning", a contemporary approach to regulation and compliance is developing. This emerging approach, called "Algorithmic Regulation", defines an alternative framework for systematic collection of data (real-time or near real-time) and continuous generation of knowledge through intelligent computational algorithms in order to regulate a domain of activities.

In this study, we will look at some of the major data management challenges in the pilot CCS operations with regards to rules and regulations. We will then discuss how an algorithmic regulatory framework can help in conducting CCS operations in a manner that are compliant with environmental, safety and health policies and regulations.

Field operators collect a lot of data which needs to be formatted and modelled in a fashion acceptable to understand the operator's compliance with regulation. Generally, such compliance qualification criteria are verified using human intellect and basic querying software. In other industries, the idea of converting rules & regulations in a format understandable by machines is gaining momentum and great strides have been taken. The technological progresses made possible by data-driven analytical techniques can create a paradigm shift in the way rules and regulations are designed and implemented. Large-scale deployment of CCS projects is bound to bring with it a number of regulatory issues, making it a necessity to proactively explore and address the anticipated issues. These technologies can equip regulated entities as well as regulators with advanced tools for managing complexity in CCS projects. These improved solutions will help companies to better meet the regulatory data collection, reporting and governance requirements in large scale CCS operations.

This paper looks into advanced data management and modeling techniques like "algorithmic regulations" to increase compliance in carbon capture and sequestration projects. The concept of handling rules and regulations in the form of big data will change the outlook and compliance management will become increasingly more agile and responsive.
Defining and Deriving the Proper Order of Movements from Prospective Resources, to Contingent Resources, to Reserves and Back
Authors: Moridis Nefeli , Quist Morgan , Lee W. John , Sim Wayne , Blasingame Thomas
Published: April 2019

This paper presents a methodology that provides the upstream oil and gas industry with a robust approach to petroleum inventory management. More specifically, we describe the proper order of movements of resources from Prospective Resources to Contingent Resources, to Reserves (and back). Our methodology describes the "causes of change in classification" and what these changes mean when classifying Reserves as well as "resources other than reserves" (ROTR).

We begin with the updated PRMS and COGEH documents (2018). We then define the three steps that are necessary to move through Prospective Resources before we can begin moving into the sub-classes of Contingent Resources. We define the movement for Prospective Resources to become discovered, making these Prospective Resources become Contingent Resources. We define the progression, following discovery, in chance of development and commerciality in the project maturity sub-classes within the Contingent Resources classification. We define the criteria for a technology to become "established" and explain that these technologies must be technically reliable and economic before they can be used for development decisions. Lastly, we define the contingencies and the movement through each contingency for the volumes to become Reserves.

The main results we provide in this work are that the movement from Prospective Resources to Contingent Resources to Reserves cannot be defined by straight movements from one class to another. This means that there is no direct path that can be used to define the movement from Prospective to Contingent Resources, though there are certain criteria that must be met regardless of the project. We also show that certain contingencies, such as price of oil and available technologies, dominate the movement of resource volumes.
Improved Methods of Measuring Proppant Conductivity
Authors: Richard Sterling , Schrader Susan , Schrader Richard , Ereaux Blake
Published: April 2019

The recent development of unconventional oil and gas reservoirs has been accompanied by a rapid expansion in hydraulic fracturing technology. A successful stimulation treatment relies heavily on the performance of the proppant used. Proppant performance has been quantified thoroughly in a laboratory setting for over 30 years through the procedures outlined in API RP61 and later API RP19D, referred to as the short-term test and long-term test, respectively. These procedures produce variable results from test to test, person to person, and lab to lab. As a result, a gross variance of ±20% about a mean is considered within laboratory accuracy for the long-term test, although variances of more than 80% have been recorded.

This variability is thought to be a consequence of the inconsistent packing structure generated by the cell loading process, which creates a loose, incompact arrangement of proppant grains. The focus of this research was the development of a new cell loading process that creates a more repeatable grain packing structure. Applying vibration to the proppant pack prior to testing was evaluated as a means of rearranging the grains into a denser, more compact structure and in turn decreasing the level of variability. A modification of the procedure defined by API RP19D was used to compare the different cell loading techniques in a timely manner. Five methods of applying vibrational energy were investigated, with successively more refined technologies used as research progressed. Preliminary results were encouraging and led to the development of two vibrational methods that substantially decreased gross variance of conductivity measurements. The cell loading technique outlined in API RP19D produced a variance ranging from 13% to 51%, with an average variance of 31% for the entirety of the stress ramp. Both vibrational methods produced variances below the threshold of 20% throughout the stress ramp, with an average variance of 6% for one vibrational method and 11% for the other. These results demonstrate the potential for a vibration modification to the cell loading process to improve the science of conductivity testing.
Spectral Acoustic Logging for Well and Reservoir Performance Evaluation for Chemical EOR Project - During Water Injection Stage

Published: April 2019

The pilot Chemical EOR project in Sabriyah Field, Kuwait is implemented applying a five-spot pattern: four injectors and one producer. The results of base-line logging campaign performed in EOR area with the purpose of appraising the current state of the reservoir before EOR implementation have been addressed earlier in [1]. The objective of this paper is to demonstrate the results and value of reservoir-oriented noise and temperature logging campaign carried out during the water injection stage, before chemical injection.

To investigate the reservoir and well parameters in EOR area, an integrated logging suite consisting of High Precision Temperature (HPT) and Spectral Noise Logging (SNL) tools was run. High-definition broadband SNL tool with a large scanning radius successfully located the active flow units including low-rate ones and differentiated between reservoir flows, behind-casing channelling and leaks in well completion components, even behind multiple barriers. HPT data were analysed to quantify flow/injection profiles by matching the simulated reservoir temperature logs with field measurements under flowing/injection and static conditions, riglessly.

The main objectives of the extensive logging campaign during water injection phase before chemical EOR were to determine the water injection profile in pilot injectors and estimate the effective thickness of the target reservoir zones being developed. It was found out that injection/flow profiles in injectors and producers drilled in a heterogeneous formation were non-uniform: the flow from injector to producer propagated mostly through highly-permeable layers. This resulted in a rapid injection water breakthrough: in the producer, water breakthrough occurred in a highly permeable zone only several feet thick. The least effective thickness (34-38% of the entire perforation zone) was found in the injectors situated to the west of the producer, while in the eastern part of the EOR area the effective thickness of the reservoir was 56-59%. It was also discovered that the underlying formation cooled off considerably after the pilot injection had started, which might be caused by water migration to the lower reservoir zones in offset injector, because no substantial water loss to the underlying formation was detected in the logged injectors.

The information obtained during the surveys will be used for updating the Chemical EOR Project to ensure injection water flow control by injecting chemicals and chart the de-risking and mitigation plan for implementing and testing during EOR pilot.

The results confirmed the possibility of using polymers during development of such kind of a heterogeneous reservoir, and requirements of more due diligence prior to the implementation of EOR pilot.

Authors: Chen Jiajun , Sun Yajuan , Liu Xiaoyang , Li Jia
Published: April 2019

Background: Hereditary ataxia is a group of neurodegenerative diseases with progressive cerebellar ataxia of the gait and limbs as the main symptoms. The genetic patterns of the disease are diverse but it is mainly divided into autosomal dominant cerebellar ataxia (ADCA) and autosomal recessive cerebellar ataxia (ARCA), and about 45 pathogenic loci have been found in ADCA. The purpose of this study was to explore the genetic defect in a Chinese family with ADCA. Methods: A three-generation Chinese family with ADCA was enrolled in this study, Exome sequencing was conducted in four family members, including the proband, and verified by Sanger sequencing. Results: The rs779393130 mutation of the CACNA1C gene co-segregated with the ataxia phenotype in this family. The mutation was not detected in 50 unaffected controls. Conclusions: The rs779393130 mutation of CACNA1C may be associated with the phenotype of the disease. The CACNA1C gene encodes the Cav1.2 (alpha-1) subunit of an L-type calcium channel and this subunit may be related to the ADCA phenotype. These findings may have implications for family clinical monitoring and genetic counseling and may also help in understanding pathogenesis of this disease.

Published: April 2019

Objective：To determine the practicability and attitudes among the elderly with Parkinson's disease (PD) in China unto the use of smartphone applications (APPs) for self-management of chronic condition.
Methods：Patients with PD who participated in the study ranged in age from 52 to 87 years. Questionnaires were collected for attitudes towards using APPs for chronic condition from 204 PD patients, and the results were statistically analyzed.
Results：The surveyed population had a smartphone ownership rate of about 65.19%; Among all patients, 82.84% were willing to use an APP for PD managing; among these patients, those who were inclined to use APPs were at younger ages, web users and with higher education, better medication adherence, longer PD courses, and worse conditions of PD（P＜0.001, P＝0.001, P＜0.001, P＝0.041, P<0.001, P＝0.013）. Additionally, the willingness of patients to use APPs for PD self-management is positively related to education level(P<0.001) while the age and PD course are negatively related to it (P=0.017, P<0.001).
Conclusion：Patients with PD have relatively low smartphone coverage. They are positive about using APP to manage PD and thus using APPs to help manage PD is a practicable method. Consequently, it is still necessary to improve the smartphones’ coverage and develop practical and handy APPs for PD self-management.

Published: April 2019

Background: Compared to the conventional oral or intravenous drug administration, epidural administration of drugs has significantly higher efficacy and safety. Experimental research on animals should be performed before applying to humans. Unlike the existing canine model, we describe a new and alternative technique of epidural and intrathecal catheterization to investigate the efficacy and safety of epidural drug administration in dogs.
Methods: Twelve adult dogs were used in this study. The procedures were performed with dogs in sternal recumbency under deep sedation. Epidural catheterization was performed at the T1–T2 intervertebral space with C-arm fluoroscopy guidance. After confirming loss of resistance, a flexible epidural catheter was passed cranially to the C2–C3 level. Intrathecal catheterization was performed through the cisterna magna with the neck slightly flexed. An 18-gauge Tuohy needle was inserted into the subarachnoid space through the atlanto-occipital space. After confirming cerebrospinal fluid leakage without bleeding, a flexible intrathecal catheter was passed caudally to the C2–C3 level.
Results: All epidural and intrathecal catheterizations were successfully performed under deep sedation without any complications.
Conclusion: The new technique of epidural and intrathecal catheterization in canines is a safe and alternative procedure for investigating the toxicity and pharmacology of epidurally administered drugs.

Complicated injury of the cervical spine is accompanied by a violation of blood circulation. This condition requires maintaining adequate perfusion pressure in order to prevent secondary damage to the spinal cord and multiple organ failure. The authors did not evaluate the effect of the urgency of spinal decompression on the severity and duration of systemic hypotension in this category of patients previously, as well as the presence of a connection between systemic hypotension and the outcome of the injury.
Objective. To determine the effect of early decompression of the spinal cord on the duration and characteristics of adrenomimetics use in the bundle of intensive care measures in the acute period of complicated injury to the cervical spine.
Material and Methods. A retrospective analysis of the treatment outcomes in 27 patients with complicated ASIA A cervical spine injury was conducted. Two groups were identified: Group I included 13 patients operated on within the first eight hours from the moment of injury; and Group II — 14 patients operated on within the period from eight to 72 hours. The analyzed parameters were: age, hemodynamic parameters, severity of organ dysfunction, duration of hemodynamic support, neurological status, time spent in intensive care unit, and length of hospital stay. Central hemodynamic parameters were registered using the impedance cardiography technique. To assess organ dysfunction, the SOFA score was used.
Results. Complicated injury of the cervical spine is accompanied by a decrease in systemic vascular resistance and cardiac index. Hemodynamic parameters and duration of hemodynamic support in groups were not statistically different. Statistically significant differences in the SOFA score between groups were obtained on the third and 10th day of the follow-up. Neurogenic shock was recorded in 70.4 % of cases. Positive dynamics of neurological deficit was observed only in two (15.4 %) patients of Group I.
Conclusion. The urgency of spinal decompression does not affect the duration of hemodynamic support, but reduces the severity of organ dysfunction and increases the risk of neurological disorder regression.

Until recently, Body Mass Index (BMI) has been used as a method for measuring the nutrient state of an individual. Two people having the same weight and height may have different nutrient states. Whenever this occurs, the use of BMI for measuring the nutrient state shall be deemed irrelevant. The anthropometry will be vital in measuring the nutrient state. On the contrary, as the development of IT progresses, so does the improvement of numerical computation. One of the computational algorithms that have been improving is probabilistic reasoning with Naive Bayesian Classification (NBC) as its method. This algorithm is intended to data classification. In this research, the NBC algorithm will be applied for measuring the human nutrient status by using anthropometry data as input system. The result of this research shows that NBC can solve this problem adequately. Research results shows total performance of this system as 93.2%.Keywords: classification, Naive Bayesian Classification (NBC), nutrition

In the development of inflammatory diseases of the pharynx, etiological factors may include viral agents, bacterial infection, mainly streptococcal nature, fungal infection, diseases of the gastrointestinal tract (GERD, gastritis). Inflammatory changes in the oral mucosa and pharynx can be manifested by the main symptoms such as a feeling of dryness in the mouth and throat, difficulty or pain when swallowing. Xerostomy is a condition that develops when saliva secretion decreases or stops and is characterized by dryness in the oral cavity. With long-term course is accompanied by psycho-emotional disorders and contributes to the development of dental diseases (stomatitis, gingivitis). Septolete total including substances such as cetylpyridinium chloride and benzidamine, has antimicrobial and anti-inflammatory and can be used as an effective etiotropic and pathogenetic therapy of inflammatory diseases of the pharynx. It is also possible to use after otorhinolaryngological interventions(tonsilectomy).

New opportunities for mucioactive therapy in patients with pathology of the respiratory tract
Authors: Svistushkin V. M. , Nikiforova G. N. , Merkushinа A. V.
Published: April 2019

The most common cause of patients referring to primary care physicians are respiratory diseases. Anatomical and physiological features of the human respiratory system and the type of etiotropic agent determine the characteristic features of the pathogenesis of respiratory pathology. The possibility of self-purification of the respiratory tract is of significant clinical importance - mucociliary clearance, but during the course of respiratory inflammatory diseases, the effectiveness of such purification suffers significantly due to the formation of edema and the increased production of a secretion more dense than the physiological norm provides. Almost all diseases of the upper and lower respiratory tract are accompanied by violations of the composition and rheological properties of the secretion and difficulties in its evacuation. The use of mucoactive drugs in the treatment of patients with inflammatory pathology of the respiratory tract has a tangible economic and clinical effect, reducing the duration of the disease, the need for systemic antibiotic therapy, the frequency and severity of relapses, a positive effect on the number of complications and quality of life. The drug Elmultsin® (erdosteinе), produced by the Russian pharmaceutical company «Obolenskoye», is a representative of a group of secretolytics and respiratory motor function stimulants, is promising for use in the treatment of patients with respiratory diseases accompanied by the formation of viscous sputum, including in conditions of adverse environmental conditions.

Published: April 2019

Acute sensorineural hearing loss is a common pathology in the human population due to impaired sound perception. Along with the widespread systemic use of glucocorticosteroids in recent years, there has been a keen interest in their local delivery via intratympanic injections or through a previously installed shunt in the eardrum. The experience of treating 40 patients with ASNHL is presented. Patients of the 1st group received a systemic course of dexamethasone, and patients of the 2nd group received dexamethasone through the superimposed perforation in the eardrum using a current frequency of 4 MHz. Audiological examination was performed before treatment, 1, 2 weeks, 1 and 6 months after treatment. Local treatment of ASNHL is as effective as their systemic use and can be used as the main one. The method of radiofrequency myringotomy is safe and convenient in treatment by intra-implantation of glucocorticosteroids into the tympanic cavity.
Application of MEEMD-ARIMA combining model for annual runoff prediction in the Lower Yellow River

Published: April 2019

The prediction of annual runoff in the Lower Yellow River can provide an important theoretical basis for effective reservoir management, flood control and disaster reduction, river and beach management, rational utilization of regional water and sediment resources. To solve this problem and improve the prediction accuracy, permutation entropy (PE) was used to extract the pseudo-components of modified ensemble empirical mode decomposition (MEEMD) to decompose time series to reduce the non-stationarity of time series. However, the pseudo-component was disordered and difficult to predict, therefore, the pseudo-component was decomposed by ensemble empirical mode decomposition (EEMD). Then, intrinsic mode functions (IMFs) and trend were predicted by autoregressive integrated moving average (ARIMA) which has strong ability of approximation to stationary series. A new coupling model based on MEEMD-ARIMA was constructed and applied to runoff prediction in the Lower Yellow River. The results showed that the model had higher accuracy and was superior to the CEEMD-ARIMA model or EEMD-ARIMA model. Therefore, it can provide a new idea and method for annual runoff prediction.

Bio-apatite based materials were prepared from bovine bone wastes (BBW) by thermal treatments using a direct flame (BBS) and annealing at 500–1,100 °C (BB500–BB1100). These low-crystalline materials were characterized by means of SEM, XRD, FTIR, TG, and pHPZC and were used for the adsorption of Hg(II) ions. A CCD-RSM design was used to optimize and analyze independent variables consisting of initial mercury concentration (10–100 mg L−1), pH (2–9), adsorbent mass (0.1–0.5 g), temperature (20–60 °C), and contact time (15–120 min). The results indicated that the order of the mercury uptakes for bio-apatite based adsorbents was BB500 > BB600 > BB800 > BB1100 > BBS > BBW. The dissolution–precipitation and ion-exchange reaction are the two dominant mechanisms for the removal of Hg(II) ions at low and high pH values, respectively. The CCD-RSM predicted maximum mercury adsorption of 99.99% under the optimal conditions of 51.31 mg L−1, 0.44 g, 6.5, 67.5 min, and 50 °C for initial mercury concentration, adsorbent mass, pH, contact time, and temperature, respectively. The findings of the present study revealed that the bio-apatite based materials, particularly BB500, are suitable and versatile adsorbents for the treatment of mercury-containing wastewater.

Published: April 2019

Management of arterial hypertension in patients with chronic kidney disease (CKD) remains a major challenge due to its high prevalence and associations with cardiovascular disease (CVD) and CKD progression. Several clinical trials and meta-analyses have demonstrated that aggressive treatment of hypertension in patients with and without CKD lowers the risk of CVD and all-cause mortality, nevertheless the effects of blood pressure (BP) lowering in terms of renal protection or harm remain controversial. Both home and ambulatory BP estimation have shown that patients with CKD display abnormal BP patterns outside of the office and further investigation is required, so as to compare the association of ambulatory versus office BP measurements with hard outcomes and adjust treatment strategies accordingly. Although renin-angiotensin system blockade appears to be beneficial in patients with advanced CKD, especially in the setting of proteinuria, discontinuation of renin-angiotensin system inhibition should be considered in the setting of frequent episodes of acute kidney injury or hypotension while awaiting the results of ongoing trials. In light of the new evidence in favor of renal denervation in arterial hypertension, the indications and benefits of its application in individuals with CKD need to be clarified by future studies. Moreover, the clinical utility of the novel players in the pathophysiology of arterial hypertension and CKD, such as microRNAs and the gut microbiota, either as markers of disease or as therapeutic targets, remains a subject of intensive research.
Evaluating Seat Belt Use in Lebanon (1997-2017)

Introduction:

The use of seat belts has made a significant contribution to the reduction of road traffic casualties, and the risk inherent with not wearing seat belts in all seats of a vehicle is now well-known worldwide. The use of seat belts has a major role in reducing fatal and nonfatal injuries in all types of motor-vehicles crashes.

Aim:

The aim of this study is to understand the reasons behind the variation in seat belt use over the past two decades in Lebanon. It analyzes the situation and suggests recommendations to improve seat belt use in Lebanon.

Design:

Nine observational studies had been conducted in Lebanon during the last two decades between 1997 and 2017, and one qualitative study was performed in 2017.

Results:

The results show a significant variation in the use of the seat belt. When enforcement efforts are in progress, seat belt use increases. While when there are no checkpoints and the enforcement of seat belt use is almost absent, a significant fall was noticed.

Discussion:

The results of this study proved the failure of the Lebanese government in saving hundreds of lives just by a simple measure of enforcing seat belt law. Although experiences from various countries prove that such laws usually have a long-lasting effect on seat belt use, Lebanon failed to pursue the successful implementation of this law due to security and political problems.

Conclusion:

During the past two decades, Lebanon witnessed continuous fluctuations in seat belt use. Outside few short enforcement campaigns, our observations showed lack in seat belt use. Our observations of seat belt use among drivers and front seat passengers showed a significant correlation between seat belt use and the enforcement of seat belt law.

The greatest national benefits from seat belt use are obtained when wearing rates are very high. This can be achieved only through a sustained enforcement campaign alongside other seat belt wearing interventions such as publicity and education.
Влияние свойств границы раздела линейной и нелинейной оптических сред на потоки энергии нелинейных поверхностных волн

AbstractProcesses of localization of field excitations in the form of nonlinear surface waves that propagate along the interface between linear and nonlinear media are considered. The existence conditions of nonlinear surface waves, which are determined by the ratio between the linear characteristics of the media, the Kerr nonlinearity coefficient, and the intensity of interaction of the wave with the interface, are analyzed. The dependences of the energy flux carried by nonlinear surface waves are calculated and analyzed. Two approaches are proposed to selection of the control parameters for determining the energy flux, which are the position of the maximum field perturbation in the nonlinear halfspace and the field amplitude at the interface. Estimates of the fluxes are found in different limiting cases, which correspond to small-amplitude field perturbations and to weak or strong interaction of a nonlinear surface wave with the interface between the media. It is shown that, in the case of small-amplitude field perturbations and the weak interaction of the wave with the interface, the flux in the linear halfspace is directly proportional to the interaction intensity of the wave with the interface, while that in the nonlinear halfspace is inversely proportional to the interaction intensity.
Tradisi Lisan Yogyakarta: Narasi dan Dokumentasi
Authors: Sulistyowati Sulistyowati
Published: April 2019

Yogyakarta is one of the provinces where people are still aware of their oral tradition. Oral tradition as a culture contains aspects of life of a society. Types of oral tradition are verbal oral traditions, half-oral traditions, and non-verbal (material) oral traditions. Narrating the tradition in written form becomes an eﬀort in documentation, both in Javanese and Indonesian narratives. To translate it from the original language (Javanese) to Indonesian language creates some problems. The narrative script of the oral tradition still requires a lot of improvements in terms of language and the content of story. This research aims to train and assist people of Yogyakarta to write down their oral traditions. The activity specifcally aims to create texts of oral tradition in Yogyakarta which can be published into a semi popular book. The program, then, should be followed up by cultural discussions on oral tradition in Yogyakarta.  =================================================================Salah satu daerah yang masyarakatnya masih sadar akan kehadiran tradisi lisan adalah Yogyakarta. Tradisi lisan sebagaikebudayaan mengandung segala aspek kehidupan yang ada di masyarakat. Jenis kelompok tradisi lisan di antaranya tradisi lisan verbal, tradisi lisan setengah verbal, dan tradisi lisan nonverbal (material). Narasi tulis tradisi lisan menjadi sebuahupaya dalam dokumentasi, baik narasi berbahasa Jawa maupun bahasa Indonesia. Adanya alih bahasa dari bahasa Jawa ke bahasa Indonesia maupun sebaliknya membuat permasalahan baru muncul. Sebagian besar narasi yang terkumpul belum sepenuhnya dapat dianggap sebagai naskah karena masih memerlukan banyak perbaikan dalam segi bahasa ataupun isi cerita. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk melatih dan mendampingi masyarakat Yogyakarta untuk menulis naskah tradisi lisan. Kegiatan pengabdian ini secara khusus bertujuan untuk menciptakan naskah tradisi lisan Yogyakarta yang dapat dipublikasikan menjadi buku semipopuler. Keberlanjutan program yang dapat dilakukan adalah terlaksananya diskusi budaya secara rutin tentang tradisi lisan Yogyakarta.
