KUR’AN-I KERİM VE KATOLİK MERYEM TEOLOJİSİ (MARIOLOGY VE KUR’AN-I KERİM)
Authors: ALICI Mustafa
Published: April 2018

Hz. Meryem hakkında Katolik teolojisindeki öğretiler, bir ilah kültüne dönüşmeizlenimi vermektedir. Kur’an, aslında Hz. Meryem’i teslis içinde göstermez. Bununyerine Kur’an, Hz. Meryem gibi bir kadının tanrılaştırılmasını öne çıkarmaktadır. Hz.Meryem’in teslise dâhil edilmesi, başka bir şeydir onun ilahlaştırılmasına vurgu başka birşeydir. Dolayısıyla Katolik inancının Meryem’e verdiği tüm bu unvanlar, ona yapılanadamalar, bayramlar, kiliselerdeki resmi ritüeller, yönelimler, onun heykelinin önündehuşu ile eğilerek dua etmek, onun ruh ve bedeniyle diri, dünyada hazır ve icraat içindeolduğuna inanmak, Kur’an’ın öne çıkardığı tevhid öğretisine göre onun ilahlaştırılmasıiçin yeter sebeplerdendir.

Authors: Ponnapalli V.A.Sankar , Jayasree P.V.Y.
Published: April 2018

Fractal array antennas are multiband and broadband array antennas having space filling capability. But large Side lobe levels and the huge number of elements are the prominent challenges in the designing of these arrays. In this paper, analysis of linear and heptagonal fractal array antennas are investigated with a three valued Morse-Thue tapering technique. Due to this fractal tapering , a notable improvement has observed in array factor properties and thinning of the elements can be achieved at the various iterations of linear and heptagonal fractal array antennas. These array antennas are analyzed and simulated by MATLAB programming.

Published: April 2018

3D reconstruction from photographies is an active research trend. The resolution of the sensors is increasing and the data processing is more accurate (not only restricted to calibrated stereo vision). In archaeological research it becomes a common way to safeguard some views of an ancient site, coupled with a manner to describe in 3D the artifacts with the same set of photographies. Archaeological scientist are now facing a complex problem to handle these digital data. An important usage is to describe semantically the artifacts. It is generally made ”by hand”, supplied by the knowledge of the scientists. We propose a solution that can perform a part of this work automatically, to generate descriptions of the obtained geometry. It combines image processing, geometry processing, 3D reconstruction. This paper aims at presenting an algorithm for 2D/3D point matching. The 3D reconstruction process of model from multiple views based on SIFT algorithm. The matching process uses a 2D mask pattern to lookup the 3D corresponding point. Experimental results show that our matching algorithm is precise, highly flexible, and can be successfully applied to a variety of 3D shapes.

Published: April 2018

A cognitive underlay two-way relay network taking into account interference links from primary transmitter to secondary receivers over Nakagami-m fading channels is analyzed in this article. In this model, a secondary system including two terminal nodes exchanges data through a decode-and-forward (DF) relay node. Under the underlay approach, all secondary transmitter must adjust transmit power to protect the primary communications. We derive the exact and asymptotic closed-form expression for the secondary system outage probability over Nakagami-m fading channels showing the system diversity. Monte-Carlo simulation are performed to verify the analysis results as well as to show the system characteristics
Biomedical Monitoring Technologies and Future Healthcare Systems

Published: April 2018

Healthcare Systems (HCSs) throughout the world undergo important changes driven by aging populations and advances in biomedical technologies. At the same time, in the current economic climate, many Western countries are struggling to reduce public spending on all kinds of services, including healthcare. With this tension between tightening budgets and skyrocketing costs, many countries are seeking to identify ways of using Information Technology (IT) and Monitoring Technologies (MTs) to improve the efficiencies of HCSs while not reducing, or possibly even improving, the quality of healthcare and their delivery. Many experiments have been in progress since the 1990s. This paper has conducted a review evaluating such HCSs in terms of advantages and drawbacks. The objective of this review is to provide some illustrative publications and works and examples of Health Information Technology (HIT) systems to finally determine the place of biomedical MTs in the future HCS. We present the healthcare delivery system (HCDS) organization with roles of the different stakeholders, state initiatives in healthcare information delivery systems and the new relation between the hospital and the home though a new equilibrium. We mentioned the increasing role of telemedicine (TM), telecare (TLC) and telemonitoring (TLM) and expectations for monitoring the elderly. These expectations lead to preventive approaches based on monitoring technologies and pervasive healthcare (PH) which made healthcare improvements and cost reductions possible. Finally, we show the challenges and opportunities of the hospital versus home healthcare delivery.

(x = 0, 0.4, 0.6 and 0.8) absorbing powders were prepared using a non-consumable vacuum melting furnace and a high energy ball milling method. The effects of Co content on the microstructure and the absorbing properties of DyNi2 powders were investigated by X-ray diffraction, scanning electron microscopy and vector network analysis. The absorbing properties of DyNi2 powders were optimized, but did not affect the composition of DyNi2 alloy with increasing Co content. With the addition of Co, the ∊″ formant frequency, μ″ formant frequency and reflection loss peak frequency of the powders shifted to higher values. The minimum reflection loss peak of DyNi1.4Co0.6 powder is about −30.65 dB with a coating thickness of 1.8 mm, and a bandwidth where R < −10 dB is 1.9 GHz.
Modelling, simulation and optimisation of pulse-reverse regime of copper, silver and gold electrodeposition
Authors: Stević Zoran , Vlahović Milica , Martinović Sanja , Dimitrijević Stevan , Ponomaryova Elena , Volkov-Husović Tatjana
Published: April 2018

Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, compared with the coatings produced by constant current modes. Pulse-reverse modes also allow the use of a higher current density, and thus the production speed of electroplating cells increases. Systems for standard electroplating of copper, silver and gold are optimised by the suitable choice of duration and intensity of the pulses. It is shown that coatings with satisfactory quality can be deposited using higher current density, different modes of pulsed current in a very short period of time, without expensive and often dangerous additives in the electrolyte. Parameters of the model for certain electrochemical systems were determined by modelling and computer simulation, so the system behaviour under different circumstances becomes predictive.
Challenge of handling a Charcot spinal arthropathy with a novel hybrid fibular autograft and expandable cage
Authors: Ohana Nissim , Benharroch Daniel , Sheinis Dimitri
Published: April 2018

A 26-year-old man, who was paraplegic for 6 years due to a motor vehicle accident, presented to the authors’ clinic following his incapacity to withstand a sitting posture, the frequent sensation of “clicks” in his back, and a complaint of back pain while in his wheelchair. On imaging, his dorsal spine showed a complete arthrodesis of the primarily fused vertebrae. However, distal to this segment, a Charcot spinal arthropathy with subluxation of T12–L1 was evident. Repair of this complex, uncommon, late complication of his paraplegia by the frequently used fusion techniques was shown to be inappropriate. A novel and elaborate surgical procedure is presented by which a complete fusion of the affected spine was secured. A left retrodiaphragmatic approach was used. Complete corpectomy of both the T-12 and L-1 vertebrae to the preserved endplates was performed. Most of the patient’s fibula was resected and shaped for engrafting. The segment of the fibula was introduced into a mesh cage, before its intramedullary implantation into the T-12 and L-1 vertebrae. This 2-step procedure combined the hybrid use of a fibular autograft and an expandable mesh cage, incorporated one into the other, in an innovative intramedullary position. This intervention allowed the patient to resume his former condition as an extremely physically active patient with paraplegia. Nine years later, an asymptomatic early-stage Charcot spine was found at L5–S1, but no treatment is planned at this point.
Validity of PROMIS in minimally invasive transforaminal lumbar interbody fusion: a preliminary evaluation
Authors: Haws Brittany E. , Khechen Benjamin , Guntin Jordan A. , Cardinal Kaitlyn L. , Bohl Daniel D. , Singh Kern
Published: April 2018

OBJECTIVE

Patient-reported outcomes are commonly used to evaluate treatment efficacy. Inefficiencies in standard measurement tools often prove to be a barrier to data collection. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to overcome these limitations. This tool implements computer-adaptive testing, which enables the assessment of physical function in fewer questions than those required for “static” metrics. In spine surgery patients, moderate to strong correlations with Oswestry Disability Index (ODI) and the 36-Item Short Form Survey (SF-36) scores have been reported for PROMIS. However, to date, data regarding the efficacy of this tool for patients undergoing minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) have been limited.

METHODS

A prospectively maintained registry of patients who have undergone primary 1- or 2-level MIS TLIF was reviewed retrospectively. Patients with incomplete PROMIS data were excluded. Changes in PROMIS physical function scores 6 weeks, 12 weeks, and 6 months after surgery were analyzed using paired t-tests. PROMIS scores were compared with traditional outcome measures, including SF-12 physical function, ODI, and visual analog scale (VAS) back and leg scores. Correlations were tested using the Pearson correlation coefficient, and the strength of association was interpreted as follows: small, 0.1 ≤ |r| < 0.3; moderate, 0.3 ≤ |r| < 0.5; and large, |r| ≥ 0.5. Statistical significance was set at p < 0.05.

RESULTS

Seventy-four patients were included in this analysis after the exclusion of those without PROMIS scores. The mean preoperative PROMIS score was 35.92 ± 6.98. Significant improvements were demonstrated in PROMIS scores 12 weeks (41.33, p < 0.001) and 6 months (43.58, p < 0.001) after surgery. PROMIS scores demonstrated a significant correlation with SF-12, ODI, and VAS leg scores (p < 0.05). Strong associations with PROMIS scores were observed for SF-12 (r = 0.650 to 0.854), ODI (r = −0.525 to −0.831), and 6-month VAS back (r = −0.693) scores.

CONCLUSIONS

Physical function as measured by PROMIS improves significantly 12 weeks and 6 months after MIS TLIF. In addition, PROMIS scores have strong correlations with SF-12 and ODI scores. These results suggest that PROMIS scores can be used as a valid assessment of physical function in MIS TLIF patients. Further work is required to determine the full benefits of this measure in other spine populations.

Published: April 2018

Harvey Cushing is widely regarded as one of the forefathers of neurosurgery, and is primarily associated with his work on intracranial pathology. However, he had a clinical and academic interest in peripheral nerve surgery. Through the courtesy of the Alan Mason Chesney Medical Archives, the surgical records of the Johns Hopkins Hospital from 1896 to 1912 were reviewed. The records of a single patient undergoing brachial plexus exploration and cervical rib resection were selected for detailed review. The operative report and accompanying illustrations demonstrate Cushing’s interest in adding approaches to the pathology of the brachial plexus to his operative armamentarium.
Medical Comorbidity in Alzheimer’s Disease: A Nested Case-Control Study
Authors: Wang Jen-Hung , Wu Ya-Ju , Tee Boon Lead , Lo Raymond Y.
Published: April 2018

Background:

Little is known about the distribution of medical comorbidities in Alzheimer’s disease (AD).

Objective:

We aimed to describe the comorbidity pattern of AD in a nested case-control study.

Methods:

Incident AD cases were identified by International Classification of Diseases codes in a random sample of 2 million individuals in Taiwan National Health Insurance program during 2001–2011. We further restricted cases to those treated with AD drugs of approved reimbursement. We sampled a set of age- and sex-matched control subjects (2:1 ratio) and employed conditional logistic regression to estimate the associations between pre-specified 14 comorbidities and AD. The clusters of multiple chronic diseases were then identified by exploratory factor analysis.

Results:

A total of 2,618 AD cases were identified during 2001–2011 with a mean age of 76.1 years and female preponderance (59%). The most common 5 comorbidities in AD were hypertension (55.1%), osteoarthritis (38.2%), depression (32.3%), diabetes mellitus (DM) (25.7%), and cerebrovascular disease (CVD) (22.7%). After adjusting for age and sex, DM, osteoporosis, depression, and CVD were significantly associated with AD. The number of comorbidity was 3-fold greater in the AD group. The cluster of hypertension, DM, and hyperlipidemia was the most common combination in old age, whereas the cluster osteoarthritis and osteoporosis was the only multimorbidity pattern significantly associated with AD.

Conclusion:

Multimorbidity is common in AD. Depression, CVD, osteoporosis, and DM are associated with incident AD, supporting that their co-existence is a typical feature of AD at old age. Comorbidity care should be integrated into current management for patients with AD.

Authors: Kim Mi-Young , Noh Yoojin , Son Sang Joon , Shin Sooyoung , Paik Hee-Young , Lee Sukhyang , Jung Yi-Sook
Published: April 2018

Background:

Ischemic heart disease (IHD) is associated with cognitive decline and may contribute to an increased risk of dementia.

Objective:

The goal of the present study was to investigate whether cilostazol use is associated with a lower risk of incident dementia in Asian patients with IHD, and whether these effects differed based on sex.

Methods:

This retrospective cohort study was performed using the Korean National Insurance Claim Data of the Health Insurance Review and Assessment Service; the duration of the study was from January 1, 2007 to December 31, 2015. The study group comprised 66,225 patients with IHD, aged >65 years, who had received cilostazol. Age- and sex-matched IHD patients without cilostazol exposure were selected as the control group. The risk of dementia was compared between the cilostazol and control groups.

Results:

Compared to the control group, total cilostazol users had a marginally significant lower risk of incident dementia. After stratification by sex, the reducing effect of cilostazol on incident dementia was significant in female participants, but not in male participants. Female patients who had cilostazol for over 2 years showed a clinically meaningful preventive effect (HR, 0.85; 95% CI, 0.82–0.88).

Conclusions:

This study suggested that cilostazol treatment may reduce the risk of incident dementia in Korean patients with IHD. Its beneficial effect was remarkably significant in female patients who received cilostazol for over a 2-year period.

Published: April 2018

Alzheimer’s disease (AD) is characterized by accumulations of amyloid-β (Aβ42) and hyperphosphorylated tau proteins, associated with neuroinflammation, synaptic loss, and neuronal death. Several studies indicate that c-Jun N-terminal kinase (JNK) is implicated in the pathological features of AD. We have investigated in 5XFAD mice, the therapeutic effects of Brimapitide, a JNK-specific inhibitory peptide previously tested with higher concentrations in another AD model (TgCRND8). Three-month-old 5XFAD and wild-type littermate mice were treated by intravenous injections of low doses (10 mg/kg) of Brimapitide every 3 weeks, for 3 or 6 months ( n = 6–9 per group). Cognitive deficits and brain lesions were assessed using Y-maze, fear-conditioning test, and histological and biochemical methods. Chronic treatment of Brimapitide for 3 months resulted in a reduction of Aβ plaque burden in the cortex of 5XFAD treated mice. After 6 months of treatment, cognitive deficits were reduced but also a significant reduction of cell death markers and the pro-inflammatory IL-1β cytokine in treated mice were detected. The Aβ plaque burden was not anymore modified by the 6 months of treatment. In addition to modulating cognition and amyloid plaque accumulation, depending on the treatment duration, Brimapitide seems experimentally to reduce neuronal stress in 5XFAD mice.
The Role of the Gut Microbiota in the Metabolism of Polyphenols as Characterized by Gnotobiotic Mice
Authors: Pasinetti Giulio Maria , Singh Risham , Westfall Susan , Herman Francis , Faith Jeremiah , Ho Lap
Published: April 2018

A growing body of experimental data suggests that microbes in the gut influence behavior and can alter brain physiology and neurochemistry. Although promising, researchers are only starting to understand the potential of the gut microbiota for use in neurological disease. Recent evidence demonstrated that gastrointestinal activities are linked to mood disorders such as anxiety, depression, and most recently, cognitive functions in age-related neurodegenerative disorders. Studies from our group and others are uncovering new evidence suggesting that the gut microbiota plays a crucial role in the metabolism and bioavailability of certain dietary compounds and synthetic drugs. Based on this evidence, this review article will discuss the implications of the gut microbiota in mechanisms of bioavailability and biotransformation with an emphasis on dietary polyphenol compounds. This will be followed by a survey of ongoing innovative research identifying the ability of individual gut bacteria to enhance the bioavailability of gut-derived, brain-penetrating, bioactive polyphenol metabolites that ultimately influence mechanisms associated with the promotion of resilience against psychological and cognitive impairment in response to stress. Lastly, current research initiatives aimed at promoting the generation of brain bioactive polyphenol metabolites by specialized gut microbes will be discussed, specifically the use of gnotobiotic mice to develop bioengineered second generation probiotics. We propose that leveraging the gut microbial ecosystem to generate brain targeted bioactive metabolites from dietary polyphenols can attenuate lifestyle risk factors and promote resilience against age-related cognitive decline.

Published: April 2018

Allelopathic potentiality of crop residues may be helpful to minimize the serious problems in the present agricultural production such as environmental pollution, unsafe products, human health concerns, depletion of crop diversity, soil sickness and reduction of crop productivity. In this phenomenon an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to November, 2015 to evaluate the effect of crop residues of wheat on weed management and crop performance of T. Aman rice. The experiment consisted of three varieties (cv. BRRI dhan32, BRRI dhan33 and BRRI dhan49) and five different treatments (viz. no crop residues, wheat crop residues @ 0.5, 1.0, 1.5 and 2.0 t ha-1). The experiment was laid out in a randomized complete block design with three replications. Five weed species belonging to three families infested the experimental plots. Weed population, weed dry weight and percent inhibition of weed were significantly influenced by wheat crop residues and cultivar. The maximum weed growth was noticed where no crop residues was incorporated and the minimum was found where @ 2.0 tha-1 wheat crop residues was incorporated. The grain yield as well as the other yield contributing characters produced in BRRI dhan49 was the highest among the studied varieties. The highest percent inhibition of 75.32, 58.24, 72.60, 57.45 and 82.24 was in Shama, Panishapla, Pani chaise, Panikachu and Susnishak, respectively which was caused by the application of wheat crop residues @ 2 t ha-1. The highest loss of grain yield was obtained where no crop residues were incorporated. The highest numbers of tillers hill-1, numbers of grains panicle-1, 1000-grain weight, grain yield, straw yield were observed where wheat crop residues were incorporated @ 2.0 t ha-1. The results of this study indicate that different amount of wheat crop residues showed potential activity to suppress weed growth.Progressive Agriculture 28 (4): 253-261, 2017

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during January to May 2015 to study the response of soybean to Bradyrhizobium biofertilizer under different levels of phosphorus on growth, yield, nutrient content and uptake by soybean. The experiment was laid out in a randomize complete block design with three replication of each treatment. The treatments were: To = Control, T1=(100% Nitrogen), T2=(Bradyrhizobium), T3=(Bradyrhizobium inoculation+75% P), T4=(Bradyrhizobium inoculation+10 P), T5=Bradyrhizobium+125% P), T6=(100% RFD+Bradyrhizobium). Potassium and Sulphur at recommended dose were applied as basal to all the treatments. Urea was applied in three spits. Phosphorus in the form of TSP was applied as per treatment during final land preparation. Soybean seeds were inoculated with Bradyrhizobium as per treatments. Intercultural operations were done as and when necessary. Data were collected on pods weight, grain and stover yields. The N and P contents in grain stover and total N and P uptake by soybean were determined. Inoculation of seeds with Bradyrhizobium and application of N and P fertilizer at recommended dose recorded the highest grain and straw yields of soybean. The results suggest that soybean cultivation can effectively be done in the Old Brahmaputra Floodplain soils by Inoculating with Bradyrhizobium biofertilizer in combination with recommended dose of N, P, K and fertilizer.Progressive Agriculture 28 (4): 302-315, 2017

We examined the hypothesis that the short term clinical and angiographic outcome of skeletonized Left Internal Mammary Artery (LIMA) is better than that of pedicled LIMA used for revascularization of left anterior descending artery at CABG surgery at the Department of Cardiac Surgery, National Heart Foundation Hospital and Research Institute from May 2011 to April 2012. Accordingly we studied 60 consecutive patients who underwent coronary artery bypass grafting, in which the LIMA was anastomosed to the left anterior descending artery (LAD). In 30 consecutive LIMAs were harvested as a pedicle (Control Group) and another 30 consecutive LIMAs were harvested as skeletonized graft (Experimental Group). Three diameters of the LIMA graft were measured quantitatively in postoperative angiograms performed 6 ± 1 month after the coronary artery bypass grafting; D1, at the origin from the subclavian artery; D2, at the level of the second intercostal space; and D3, just proximal to the anastomosis. Our study shows that, complete skeletonization results in increased graft length 19.71 ± 1.77 cm in skeletonized group vs. 17.08 ± 0.71cm in pedicle group (p <0.001). Although there was similar incidence of superûcial wound complications between the groups, the post CABG pain (PCP) was significantly higher in pedicled group at the 6 month follow-up. Check coronary angiography showed the LIMA grafts to the LAD were all patent. There was increased diameter achievement in skeletonized group at the anastomotic site (D3: 1.78 ± 0.21 mm vs. 1.66 ± 0.18 mm; p = 0.03). We conclude that skeletonized LIMA showed a better functional behavior, giving longer conduit length and superior postoperative clinical and angiographic profile.University Heart Journal Vol. 12, No. 2, July 2016; 82-87

To develop high capacity electrode materials for lithium-ion battery (LIB), dissimilar materials are mixed and, as a result, carbon nanofibers containing silicon (Si) nanoparticles and its components are successfully created by electrospinning method and some heat treatments. Tetraethoxysilane (TEOS) and Si nanoparticles are adopted as additives of carbon nanofibers because of their huge potential for obtaining high capacity. In this research, therefore, we develop TEOS/Si hybrid carbon nanofibers. Consequently, some samples obtain much higher charging/discharging capacity than the theoretical capacity for graphite (372 mAh/g, LiC6) even after second cycle.

It is still a challenge to synthesize non-precious-metal catalysts with high activity and stability for the oxygen reduction reaction (ORR) to replace the state-of-the art Pt/C catalyst. Herein, a Fe, N, S co-doped porous carbon (Fe-NS/PC) is developed by using g-C3N4 and 2,4,6-tri(2-pyridyl)-1,3,5-triazine (TPTZ) as binary nitrogen precursors. The interaction of binary nitrogen precursors not only leads to the formation of more micropores, but also increases the doping amount of both iron and nitrogen dispersed in the carbon matrix. After a second heat-treatment, the best Fe/NS/C-g-C3N4/TPTZ-1000 catalyst exhibits excellent ORR performance with an onset potential of 1.0 V vs. reversible hydrogen electrode (RHE) and a half-wave potential of 0.868 V (RHE) in alkaline medium. The long-term durability is even superior to the commercial Pt/C catalyst. In the meantime, an assembled Zn-air battery with Fe/NS/C-g-C3N4/TPTZ-1000 as the cathode shows a maximal power density of 225 mW·cm−2 and excellent durability, demonstrating the great potential of practical applications in energy conversion devices.
A Symmetric Plaintext-Related Color Image Encryption System Based on Bit Permutation

Published: April 2018

Recently, a variety of chaos-based image encryption algorithms adopting the traditional permutation-diffusion structure have been suggested. Most of these algorithms cannot resist the powerful chosen-plaintext attack and chosen-ciphertext attack efficiently for less sensitivity to plain-image. This paper presents a symmetric color image encryption system based on plaintext-related random access bit-permutation mechanism (PRRABPM). In the proposed scheme, a new random access bit-permutation mechanism is used to shuffle 3D bit matrix transformed from an original color image, making the RGB components of the color image interact with each other. Furthermore, the key streams used in random access bit-permutation mechanism operation are extremely dependent on plain image in an ingenious way. Therefore, the encryption system is sensitive to tiny differences in key and original images, which means that it can efficiently resist chosen-plaintext attack and chosen-ciphertext attack. In the diffusion stage, the previous encrypted pixel is used to encrypt the current pixel. The simulation results show that even though the permutation-diffusion operation in our encryption scheme is performed only one time, the proposed algorithm has favorable security performance. Considering real-time applications, the encryption speed can be further improved.
Influence of Fracture Heterogeneity Using Linear Congruential Generator (LCG) on the Thermal Front Propagation in a Single Geothermal Fracture-Rock Matrix System

Published: April 2018

An implicit finite difference numerical model has been developed to investigate the influence of fracture heterogeneity on the propagation of thermal front in a single horizontal fracture-matrix system. Instead of depending on a complex and data-demanding geostatistical method for a precise representation of fracture aperture, a statistical linear congruential generator (LCG) method was applied in the present study to replicate the unpredictable nature of fracture aperture morphology. The results have been compared with the parallel plate model and simple sinusoidal model. Finally, sensitivity analysis of fracture aperture size and fluid flow rate has been carried out to identify the conditions at which fracture heterogeneity is critical. The results indicate that LCG-aperture enhances the heat transfer between fracture and hot rock matrix compared to the parallel and sinusoidal fractures. Further, the temperature profiles in hot rock indicate that there was a greater loss of heat for the case of LCG-aperture (25% loss) compared to sinusoidal (16%) and parallel plate (8%) apertures. It was found that heterogeneity does not play a major role at small fracture aperture size (≤50 μm) and at low flow rates. However, as fracture aperture size increases, the heterogeneity plays a vital part even at low flow rates.

Published: April 2018

It has been shown that using nanofluids as heat carrier fluids enhances the conductive and convective heat transfer of geothermal heat exchangers. In this paper, we study the stability of nanofluids in a geothermal exchanger by numerically simulating nanoparticle sedimentation during a shut-down process. The nanofluid suspension is modeled as a non-linear complex fluid; the nanoparticle migration is modeled by a particle flux model, which includes the effects of Brownian motion, gravity, turbulent eddy diffusivity, etc. The numerical results indicate that when the fluid is static, the nanoparticle accumulation appears to be near the bottom borehole after many hours of sedimentation. The accumulated particles can be removed by the fluid flow at a relatively high velocity. These observations indicate good suspension stability of the nanofluids, ensuring the operational reliability of the heat exchanger. The numerical results also indicate that a pulsed flow and optimized geometry of the bottom borehole can potentially improve the suspension stability of the nanofluids further.

Published: April 2018

To investigate turbulent reacting flows, a low-Mach number large-eddy simulation (LES) code called ‘LESsCoal’ has been developed in our group. This code employs the Germano dynamic sub-grid scale (SGS) model and the steady flamelet/progress variable approach (SFPVA) on a stagger-structured grid, in both time and space. The method of manufactured solutions (MMS) is used to investigate the convergence and the order of accuracy of the code when no model is used. Finally, a Sandia non-reacting propane jet and Sandia Flame D are simulated to inspect the performance of the code under experimental setups. The results show that MMS is a promising tool for code verification and that the low-Mach-number LES code can accurately predict the non-reacting and reacting turbulent flows. The validated LES code can be used in numerical investigations on the turbulent combustion characteristics of new fuel gases in the future.
A DAB Converter with Common-Point-Connected Winding Transformers Suitable for a Single-Phase 5-Level SST System

Published: April 2018

One of the main disadvantages of the multi-level solid-state transformer (SST) system is the voltage imbalance on the output of the rectifier modules. This voltage imbalance can be caused by parameter mismatch of the active and passive components, different loads, and the floating structure of the high voltage DC-links. Some studies have been done to solve this voltage imbalance problem. A common way to avoid this imbalance is to balance the voltage of DC-links at the AC/DC conversion stage and balance the power between the modules at the DC/DC conversion stage. Most of these methods require a complex balancing controller or additional circuits. This paper proposes a novel dual active bridge (DAB) converter specialized in power balancing in a single-phase 5-level SST system. The proposed DAB converter does not require any additional balancing controllers or techniques for power balancing. The performance of the proposed DAB converter was verified by simulation and experiments using a 3 kW 5-level SST prototype system.

Published: April 2018

This paper introduces a distributed secondary control algorithm for automatic generation control (AGC) and automatic voltage control (AVC), which aims at matching area generation to area load and minimizing the total generation cost in an alternating current (AC) microgrids. Firstly, the control algorithm utilizes a continuous-time distributed algorithm to generate additional control variables to achieve frequency-voltage recovery for all distributed generators (DGs). Secondary, it solves the economic dispatch problem (EDP) by a distributed economic incremental algorithm in the secondary control level, which avoids the problem caused by communication speed inconsistency between secondary and tertiary control levels. This study also utilizes a fully distributed strategy based on secondary communication network to estimate the total load demand. In addition, the proposed algorithm can be used to realize a seamless handover from the islanded mode to the grid-connected mode, run under the condition of short time communication system out of action, and help to realize the plug and play function. Lastly, the stability of the proposed control algorithm is analyzed and proved, and the effectiveness of the method is verified in some case studies.

Authors: Zhang Juwen
Published: April 2018

This article first outlines the long history of folklore collection in China, and then describes the disciplinary development in the 20th century. In Section 3, it presents the current situation in terms of disciplinary infrastructure, development, contribution, and challenge, with a focus on the recent practice of safeguarding Intangible Cultural Heritage. These accounts are largely based on the views of the Chinese folklorists. In the final section, this article discusses the issues of cultural continuity, integration, and self-healing mechanisms in Chinese culture by putting Chinese folkloristics in a historical and world perspective. This paper suggests that, to understand Chinese folklore and culture, one must be aware of the most basic differences between Chinese fundamental beliefs and values and those of theWest, and that Chinese folklore and folkloristics present new challenges to the current paradigms put forward in the post-colonial, post-modern, and imperial ideologies.

Published: April 2018

Karst areas are typical ecologically fragile areas, and stony desertification has become the most serious ecological and economic problems in these areas worldwide as well as a source of disasters and poverty. A reasonable sampling scale is of great importance for research on soil science in karst areas. In this paper, the spatial distribution of stony desertification characteristics and its influencing factors in karst areas are studied at different sampling scales using a grid sampling method based on geographic information system (GIS) technology and geo-statistics. The rock exposure obtained through sampling over a 150 m × 150 m grid in the Houzhai River Basin was utilized as the original data, and five grid scales (300 m × 300 m, 450 m × 450 m, 600 m × 600 m, 750 m × 750 m, and 900 m × 900 m) were used as the subsample sets. The results show that the rock exposure does not vary substantially from one sampling scale to another, while the average values of the five subsamples all fluctuate around the average value of the entire set. As the sampling scale increases, the maximum value and the average value of the rock exposure gradually decrease, and there is a gradual increase in the coefficient of variability. At the scale of 150 m × 150 m, the areas of minor stony desertification, medium stony desertification, and major stony desertification in the Houzhai River Basin are 7.81 km2, 4.50 km2, and 1.87 km2, respectively. The spatial variability of stony desertification at small scales is influenced by many factors, and the variability at medium scales is jointly influenced by gradient, rock content, and rock exposure. At large scales, the spatial variability of stony desertification is mainly influenced by soil thickness and rock content.
Nature Disaster Risk Evaluation with a Group Decision Making Method Based on Incomplete Hesitant Fuzzy Linguistic Preference Relations
Authors: Tang Ming , Liao Huchang , Li Zongmin , Xu Zeshui
Published: April 2018

Because the natural disaster system is a very comprehensive and large system, the disaster reduction scheme must rely on risk analysis. Experts’ knowledge and experiences play a critical role in disaster risk assessment. The hesitant fuzzy linguistic preference relation is an effective tool to express experts’ preference information when comparing pairwise alternatives. Owing to the lack of knowledge or a heavy workload, information may be missed in the hesitant fuzzy linguistic preference relation. Thus, an incomplete hesitant fuzzy linguistic preference relation is constructed. In this paper, we firstly discuss some properties of the additive consistent hesitant fuzzy linguistic preference relation. Next, the incomplete hesitant fuzzy linguistic preference relation, the normalized hesitant fuzzy linguistic preference relation, and the acceptable hesitant fuzzy linguistic preference relation are defined. Afterwards, three procedures to estimate the missing information are proposed. The first one deals with the situation in which there are only n − 1 known judgments involving all the alternatives; the second one is used to estimate the missing information of the hesitant fuzzy linguistic preference relation with more known judgments; while the third procedure is used to deal with ignorance situations in which there is at least one alternative with totally missing information. Furthermore, an algorithm for group decision making with incomplete hesitant fuzzy linguistic preference relations is given. Finally, we illustrate our model with a case study about flood disaster risk evaluation. A comparative analysis is presented to testify the advantage of our method.
