A remote field eddy current probe for outside inspection of pipe defects
Authors: Xu Zhiyuan , Lin Zhangpeng , Xiao Qi
Published: November 2018

A remote field eddy current (RFEC) probe for in-service inspection of pipe defects is presented. Firstly, based on finite element analysis, the probe is designed with an external and circumferentially aligned structure. Afterwards, the simulation model of RFEC testing for defect detection is established, and the quantitative relations of the inner diameter (ID) and outer diameter (OD) defect depth to the signal features are analysed. Finally, experimental verification is performed. The results show that: (i) the probe signal phase decreases almost linearly with the increase of ID or OD defect depth, which can be used to quantify defect depth; (ii) the ID or OD defect depth can be quantified respectively, but, due to the different sensitivity to ID and OD defects, it is still hard to quantify the depth when two types of defect exist simultaneously; and (iii) the defect orientation has little effect on the signal phase.

Published: November 2018

This paper proposes a novel hybrid-excited wound-rotor synchronous machine (HE-WRSM) with asymmetrically positioned permanent magnets (PMs) to make full use of reaction torque and reluctance torque, thus to improve the machine performance, including torque, efficiency, and power factor. To highlight the advantage of the proposed HE-WRSM, the conventional WRSM and HE-WRSM are adopted for performance comparison under the same operating conditions. All machine characteristics are predicted by the finite element method (FEM) using the commercial software, JMAG-Designer. The analysis results finally demonstrate that the proposed HE-WRSM exhibits highly improved torque, power factor, and efficiency, when compared to the conventional machines. Furthermore, the proposed HE-WRSM is verified to have superior endurance against the magnet irreversible demagnetization within two times of the rated current excitation.

Published: November 2018

In this paper, an improved configuration of the rotor for an Electric Controlled Permanent Magnet Synchronous machine (ECPMS-machine) is proposed by introducing axial bridges made by lamination or Soft Magnetic Composite (SMC) material in order to minimize mass and iron losses in the rotor. In addition, the influence of the small air-gap in the bridge lamination on a field-weakening range (FWR) of the machine is evaluated by three-dimensional finite-element analysis (3-D FEA). Moreover, the phase back-electromotive force (back-EMF) waveforms achieved by simulation for three novel rotor concepts at different DC coil currents are reported and compared with experimental results obtained on a machine prototype.

Published: November 2018

A proposed permanent magnetic suspension using flux path control has quasi-zero power characteristic since its unique structure realizes transmitting the suspended object’s gravity the system frame, and the motor just drives the permanent magnet to rotate and suffers a small regular torque caused of the system magnetic potential. The small regular torque will deteriorate the system’s response characteristics and suspension stability. This paper optimizes the system structure for improving the quasi-zero power characteristic. Firstly, the structure and the suspension principle of the former system is introduced, and the rotational torque on the motor’s shaft was measured using an experimental prototype. Secondly, a symmetric offset optimal structure was proposed through analyzing the experimental results of rotational torque, and the torque on the motor’s shaft was calculated by using a FEM model. The simulation results indicate that the rotational torque was reduced to about 15% of the former structure using the optimized structure with a magnetic separation iron plate. Finally, the experimental prototype with the optimized structure was manufactured, and the measurement experiment for the torque was carried out. The experiment results verified the validity of the simulation results and the optimizations.
Fast computation of the response of any 3D Eddy Current probe scanning a 3D stratified conductor characterized by a set of arbitrary interfaces of complex shape
Authors: Prémel Denis , Granet Gérard
Published: November 2018

This paper concerns the development of a semi-analytical model dedicated to the fast computation of the response of a 3D Eddy Current (EC) probe scanning a planar conductor of complex shape. The workpiece is characterized by a finite number of complex interfaces k, 1 ≤ k ≤ N, each one being defined by any 2D arbitrary surface a k( x, y). A previous semi-analytical model based on the Curvilinear Coordinate Method (CCM) has been presented for the computation of quasi-static fields induced by any 3D EC probe scanning a half-space of complex shape. This paper gives a natural extension of this preliminary work. CCM consists in introducing a change of coordinates in order to be able to write analytically and easily boundary conditions separating two media. No mesh is needed, nevertheless, the covariant form of Maxwell’s equations is required due to a novel generalized metric space. Boundary conditions at multiple interfaces are efficiently implemented thanks to the S-matrix algorithm. Finally, some numerical experiments show the validity of the numerical model by some comparison between simulated data obtained by a FE commercial code and those provided by the proposed numerical model.

Authors: Yamaguchi Toshihiko , Mihalache Ovidiu , Ueda Masashi
Published: November 2018

The paper presents the progress in the developments of an electro-magnetic acoustic transducer (EMAT) based on a Halbach magnet system optimized for detection of defects in thick plates with application to the inspection of fast breeder reactors (FBR) vessel. The defects are located either far or near weld lines in austenitic stainless steel plates (50 mm thick), on the opposite plate side where are located the EMAT sensors. Performance of single or double units EMATs are investigated for working in industrial conditions with very long cables (up to 45 m). Experimental measurements are focused on an increased signal/noise ratio for detection of signal from defects located near weld lines of FBR vessel. A fast and novel way of EMAT measurements and signal processing (named dynamic scanning) is introduced and its performance is confirmed for austenitic stainless steel plate defects with depths ranging from 5% to 50% from the plate thickness.

Authors: Maruo Akito , Igarashi Hajime
Published: November 2018

The chaotic vibration energy harvester (CVEH) converts vibration of constructions to electric energy in wide frequency. It needs large computational cost for evaluation of the magnetic force between the moving magnets and magnetic material embedded in the stator coils of CVEH when using finite element method (FEM). This paper presents magnetic circuit modeling of CVEH to reduce computational burden. It is shown that the frequency responses of CVEH computed by the present method is in good agreement with those obtained by FEM. This result is validated through the experiment.

Authors: Wondrak Thomas , Galindo Vladimir , Stefani Frank , Jacobs Ralf T.
Published: November 2018

The Contactless Inductive Flow Tomography is a procedure that enables the reconstruction of the global flow structure of an electrically conducting fluid by measuring the flow induced magnetic field outside the melt and subsequently solving the associated linear inverse problem. The accuracy of the reconstruction depends on the number and the distribution of the sensors around the vessel. The aim of this investigation is to find a sensor configuration for the reconstruction of a temperature driven flow of a liquid metal in a cylindrical vessel that employs as few sensors as possible without any significant loss of accuracy.

Authors: Zhao Yongxia , Xu Yize , Bao Yunfeng , Geng Xue , Zhang Tianle , Li Dongxue
Published: November 2018

OBJECTIVE:

To assess the difference in absorbed organ dose and image quality for head-neck CT angiography using organ dose modulation compared with 3D smart mA modulation in different body mass indices (BMIs) using an adaptive statistical iterative reconstruction (ASiR-V) algorithm.

METHODS:

Three hundred patients underwent head-neck CTA were equally divided into three groups: A (18.5 kg/m2≦BMI < 24.9 kg/m2), B (24.9 kg/m2≦BMI < 29.9 kg/m2) and C (29.9 kg/m2≦BMI≦34.9 kg/m2). The groups were randomly subdivided into two subgroups ( n = 50): A1-A2, B1-B2 and C1-C2. The patients in subgroups A1, B1 and C1 underwent organ dose modulation with the ASiR-V algorithm, while other patients underwent 3D smart mA modulation. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of all head-neck CT angiography images were calculated. Images were then subjectively evaluated. Mean values of several indices including dose-length product (DLP) were computed. The DLP was converted to the effective dose (ED). SNR, CNR and ED in groups A, B, and C were compared in statistical data analysis.

RESULTS:

SNR, CNR, and subjective image scores show no statistical differences in three groups ( P  >  0.05). However, there is significant difference of ED values ( P  <  0.05) . For example, in subgroup A1 mean ED values are 15.30% and 23.66% lower than those in subgroup A2 at thyroid gland and eye lens, respectively. Similar patterns also exist in groups B (B1 vs. B2) and C (C1 vs. C2).

CONCLUSIONS:

Using organ dose modulation and applying the ASiR-V algorithm can more effectively reduce the radiation dose in head-neck CT angiography than using 3D smart mA modulation, while maintaining image quality. Thus, using organ-based dose modulation has the additional benefit of reducing dose to the thyroid gland and eye lens.

Exclusive breastfeeding for 6 months is a global strategies to promote the growth, development, health and survival of infants. Despite the many benefits of exclusive breastfeeding for infants, mothers, families and communities, the coverage is still low in many countries including Indonesia. Mother's milk is produced from the collaboration between mechanical stimulation of hormonal and nerve factors. One of the hormones that affects is the estrogen. The hormone estrogen is a sex hormone produced by the uterus to stimulate the growth of sex organs such as breasts and pubic hair and regulate the menstrual cycle. The hormone estrogen also plays a role to maintain the texture and function of the breast. Pregnancy in a woman, making the breast gland will be more developed by the influence of estrogen, somatomamotropin and prolactin hormones. The process is affected by the hormones estrogen and progesterone. Estrogen significantly stimulates the synthesis and release of pituitary hormone, this effect depends on the duration and dose of administration. In Indonesia, moringa plant is a local food that has the potential to be developed in culinary breastfeeding mothers because it contains phytosterol compounds that function to improve and facilitate the production of breast milk (laktogogum effect). This paper will discuss some of the facts about the effect of Moringaoleifera extract on prolactin levels in increasing the quantity and quality of breast milk in the breastfeeding process. The amount of nutrients in the Moringa leaf (Moringaoleifera) one such as phytosterol compounds (laktogogum effect) in increasing levels of pituitary hormone and iron hormones can have a positive impact on the health of the baby because breast milk is the most important and best natural baby food.

Authors: Irfannudin Irfannudin
Published: November 2018

Methods of biomolecular analysis on protein through bioinformatics media has been growing rapidly. This report is intended to describe the results of biomolecular amyloid precursor protein (APP) analysis and the characteristic change of APP mutations causing cognitive degeneration disorder through bioinformatics media and search to reliable biomolecular sites.  APP is a transmembrane protein that is widely present in neuronal tissue. APP plays an important role for the formation of neuronal cells. The APP gene is located on the 21st chromosome that has 290,586 base pairs (bp) of 20 exons and 19 introns. In the form of a protein, APP consists of 770 amino acids with major expressions located on the cell surface. Mutation of APP genes is believed to play a role in the incidence of Alzheimer's disease. One of the mutations studied in this paper is the mutation of Alanin to Glysin at the position of the 692 amino acid (APP mutant A692G). This mutation affects the impairment of cerebral amyloid angiopathy belonging to the Alzheimer Disease Familial-1 group.These mutations do not cause changes in predictions of secondary structures and only cause slight changes in molecular weight, amino acid composition, atomic composition, aliphatic index, hydroplasticity and stability index. APP A692G mutation does not alter topology, hydrophobicity, cutting prediction and protein location prediction. Mutation also removes only the side chains at the position of the mutated amino acids.

Low Birth Weight (LBW) is an infant born with a birth weight of less than 2500 grams regardless of gestation. Birth weight is the weight of the baby weighed in 1 hour after birth. (Depkes RI, 2009). Based on WHO and UNICEF data, in 2013 about 222 million babies were born in the world, of which 16% were born with low birth weight. The percentage of LBW in developing countries is 16.5% twice that of developed countries (7%) (Scholar Unand, 2014). The purpose of this study was to determine whether there is a relationship between anemia and Smoking Habit in Pregnant Women with LBW occurrence in General Hospital Dr. Mohammad Hoesin Palembang Year 2016. This research use analytical survey method with cross sectional approach. The population in this study were all mothers who gave birth monthly in Midwifery Installation of Dr. General Hospital Mohammad Hoesin Palembang in 2016 as many as 315 respondents. The sample of this research is some of mothers who give birth enough month in Midwifery Installation of Dr. General Hospital Mohammad Hoesin Palembang Year 2016 as many as 315 respondents. ". From the results of bivariate analysis of anemic respondents with the occurrence of LBW obtained statistical test X2 count = 23.22 which means there is a significant relationship between anemia with the incidence of BBLR. Respondents smoking with the occurrence of LBWR obtained statistical test X2 count = 41.20 which means there is a relationship Meaningful between smoking and LBW incidence. From the results of this study is expected that this research can be a reference material and is a complete information and useful for the development of knowledge about LBW.

TO IDENTIFY THE COMPONENT PRESENT IN ASS URINE FOR TREATMENT OF EPILEPSY
Authors: Mishra Anuj
Published: November 2018

Approximately 150 L of plasma are purified each day by glomerular filtration, tubular secretion, and tubular reabsorption to produce 0.6 to 2.5 L of urine. The amount of urine produced is influenced by environmental temperature, fluid intake, time of day, emotional state, and many other factors.1

The composition of urine reveals much about body function. Metabolic waste products such as carbon dioxide, urea, uric acid, creatinine, sodium chloride, and ammonia are normally present and have no particular pathological significance. The presence of albumin (a protein), glucose, ketones, and various other substances, however, may indicate malfunction of the kidneys or some other organ of the body.1

Biological importance of Ass urine: (Sanskrit :khara; Latin : Asinusequidae) The urine of Ass has been mentioned useful as destroyer of epilepsy (apasmara), intensity (unmada) and in seizures. The mode of its use has been mentioned as internal as drink. Apart from the above mentioned diseases, the urine of Ass has also been prescribed to cure diabetes and various diseases caused by worms.2,3
FORMULATION AND CHARACTERIZATION OF TRANSDERMAL PATCHES OF TOLBUTAMIDE
Authors: Chetna Ms
Published: November 2018

The Skin is one of the most extensive organs of the human body. This multilayered organ receives approximately one-third of all blood circulating through body. With a thickness of about a millimeter, the skin separates the underlying blood circulation network from the outside environment1.

Transdermal delivery of drugs through the skin to the systemic circulation provides a convenient route of administration for a variety of clinical indications. Transdermal delivery systems are currently available containing scopolamine (hyoscine) for motion sickness, clonidine and nitroglycerin for cardiovascular disease, fentanyl for chronic pain, nicotine to aid smoking cessation2.

Drug molecules in contact with the skin surface can penetrate by three potential pathways: through the sweat ducts, via the hair follicles and sebaceous glands (collectively called the shunt or appendageal route), or directly across the stratum corneum3.

 

All transdermal drug delivery systems consist mainly of:

Polymer matrix

Drug

Enhancers and other excipients

Other excipient
SHORT REVIEW ON DNA-FINGERPRINTING AND STANDARDIZATION OF HERBAL DRUGS
Authors: Minocha Sakshi
Published: November 2018

Medicinal plants play a key role in world health. In spite of new advances developed in modern medicines, herbal formulations are extensively used as therapeutic agents for treatment of several diseases. Herbal drug technology is used for converting botanicals materials into medicines. Standardization is a process of evaluating the quality & purity of crude drug by various parameters like morphological, microscopical, physical, chemical &biological observation. Fingerprint analysis approach is the most important in quality control of herbal medicines because of its accuracy and reliability. DNA fingerprinting is defined as the application of genetic/ molecular marker techniques which is used to identify cultivars. Fingerprinting is a process as it determines the concentrations of chemical substances in an herb by several methods like RFLP, AFLP, RAPD, SSR sequencing of rDNA-ITS region and DNA bar-coding. Development of fingerprints based on DNA markers is necessary for proper identification and standardization of plant species.
MUCOADHESIVE AND MICROSPHERE: A SHORT REVIEW
Authors: Singh Preeti , Tibrewal Richa
Published: November 2018

Microsphere constitutes an important part of novel drug delivery system by virtue of their small size and efficient carrier capacity. Due to their short residence time, bioadhesive characteristics can be coupled to microsphere to develop mucoadhesive microsphere. Bioadhesion defined as state in which two materials, at least one of which is biological in nature, are held together for a prolonged time by the way of interfacial forces. Microsphere are the carrier around drug delivery system in which particle size in ranges from 1-1000 μm range in diameter having a core of drug and entirely outer layers of polymers as coating material. Mucoadhesive microsphere have advantages like efficient absorption and enhanced bioavailability of drugs due to high surface of volume ratio, a much more intimate contact with mucus layer, controlled and sustained release of drug from dosage form and specific targeting of drug to absorption site. This study aim to provide an overview of various aspects of mucoadhesive microsphere based on various polymers, method of preparation of mucoadhesive microsphere, method of evaluation and their applications in drug delivery system.Keywords: Mucoadhesive, microsphere, bioavailability.
A case of cirrhosis with severe hyponatremia

Published: November 2018

Cirrhosis of the liver commonly leads to a state of chronic hypervolemic hyponatremia. Profound exacerbation of the hyponatremic state may occur in patients with decompensated cirrhosis in conjunction with acute stressors such as infection. Hyponatremia in cirrhosis is associated with increased morbidity and mortality. we report a case of52 year old man with a history of alcoholic cirrhosis presented to the hospital with symptomatic profound hyponatremia (serum sodium concentration of 102 meq/L). The patient was treated with antibiotics, diuretics and hypertonic saline and was placed on a fluid restricted diet. The serum sodium level corrected slowly over four days with symptomatic improvement occurring after five days. In patients with cirrhosis, it is important to recognize the symptoms of hyponatremia, identify and treat any exacerbating conditions early in their course, and correct the serum sodium concentration slowly with frequent monitoring. Key words: hyponatremia, cirrhosis, liver
Recent trends in Component Based software development and Efficiency analysis of Semantic search based component retrieval Technique
Authors: Sharma Vishnu , Rathore Vijay Singh
Published: November 2018

In these days most of the software development uses preexisting software components. This approach provides plenty of benefits over the traditional development. Most of the software industries uses their own domain based software libraries where components resides in the form of modules, codes, executable file, documentations, test plans which may be used as it is or with minor changes. Due to shrinking time and high demand of software development it is necessary to use pre tested software components to ensure high functionality in software developed. Software components can be used very easily and without having the worries of errors and bugs because these are developed under expert supervision and well tested. What we have to do is just embed these components in our project. In this paper a survey got conducted over 112 software developer,testers and freelancers. In survey several issues in CBSD were identified. An efficient repository along with a component search engine is developed. All the component retrieval techniques were evaluated and compared with precise and recall method.
Rebuttal to : ‘The formulation of dynamic Newtonian advanced gravity, DNAg’
Authors: Sfarti Adrian
Published: November 2018

In this short note we rebut the claims made by Andrew Worsley. The author claims that “the equations for gravity can be adapted by defining the equations for the curvature of space–time in terms of geodesics. Using these equations, we translate this curvature back into equations for an advanced Newtonian force of gravity.” when, in reality he simply generates an ansatz that is falsified by existent experiments, experiments that the author is unaware of.
