A numerical study of a plane wall jet with heat transfer

Abstract A direct numerical simulation (DNS) of a wall jet is performed at R e = 7500 . To the authors’ knowledge, this is the highest Reynolds number DNS study of a wall jet. The heat transfer process is studied with an iso-thermal boundary condition at the wall. The molecular Prandtl number is P r = 0.71 . Mean flow and heat transfer parameters are contrasted with available measurements and Nusselt number coefficient correlations. The scaling parameters for heat transfer variables are investigated. The mean temperature ⟨T⟩, temperature root mean square Trms, streamwise ⟨u′T′⟩ and wall normal 〈v′T′〉 heat flux profiles show collapse in the streamwise direction, with the inner scaling, the outer scaling and the thermal scaling parameters. The complete budgets for temperature variance ⟨T′T′⟩ and turbulent heat fluxes are also presented.
RoughDroid: Operative Scheme for Functional Android Malware Detection

There are thousands of malicious applications that invade Google Play Store every day and seem to be legal applications. These malicious applications have the ability to link the malware referred to as Dresscode created for network hacking as well as scrolling information. Since Android smartphones are indispensable, there should be an efficient and also unusual protection. Therefore, Android smartphones usually continue to be safeguarded from novel malware. In this paper, we propose RoughDroid, a floppy analysis technique that can discover Android malware applications directly on the smartphone. RoughDroid is based on seven feature sets (FS1,FS2,…,FS7) from the XML manifest file of an Android application, plus three feature sets (FS8,FS9, and FS10) from the Dex file. Those feature sets pass through the Rough Set algorithm to elastically classify the Android application as either benign or malicious. The experimental results mainly consider 20 most common malware families, plus three new malware families (Grabos, TrojanDropper.Agent.BKY, and AsiaHitGroup) that invade Google Play Store at 2017. According to the experimental results, RoughDroid has 95.6% detection performance for the malware families at 1% false-positive rate. Finally, RoughDroid is a lightweight approach for straightly examining downloaded applications on the smartphone.
Effects of transcutaneous electrical nerve stimulation alone or as additional therapy on chronic post-stroke spasticity: systematic review and meta-analysis of randomized controlled trials

Abstract Purpose: To evaluate the effects and to compare transcutaneous electrical nerve stimulation protocols, alone or as additional therapy in chronic post-stroke spasticity through a systematic review and meta-analysis of randomized clinical trials. Methods: Search was conducted in MEDLINE, Cochrane Library, EMBASE and Physiotherapy Evidence Database through November 2017 (CRD42015020146). Two independent reviewers performed articles selection, data extraction and methodological quality assessment using the Cochrane Collaboration’s risk of bias tool. The main outcome was spasticity assessed with Modified Ashworth Scale or other valid scale. Meta-analysis was conducted using random effects method, and pooled-effect results are mean difference with 95% confidence interval. Results: Of 6506 articles identified, 10 studies with 360 subjects were included in the review. Transcutaneous electrical nerve stimulation alone or as additional therapy is superior to placebo TENS to reduce post-stroke spasticity assessed with Modified Ashworth Scale (−0.52 [−0.74 to −0.30] p < 0.0001, 6 studies), especially in lower limbs (−0.58 [−0.82 to −0.34] p < 0.0001, 5 studies), which is in accordance with the studies that used other scales. Low frequency TENS showed a slightly larger improvement than high-frequency, but without significant difference between subgroups. Most studies present low or unclear risk of bias. Conclusion: Transcutaneous electrical nerve stimulation can provide additional reduction in chronic post-stroke spasticity, mainly as additional therapy to physical interventions. Studies with better methodological quality and larger sample are needed to increase evidence power. Implications for Rehabilitation Transcutaneous electrical nerve stimulation as additional treatment to physical interventions can lead to additional reduction in chronic post-stroke spasticity. High and low frequency transcutaneous electrical nerve stimulation showed similar results, with a smaller numerical superiority of low frequency TENS. More studies are needed to substantiate the best protocol of transcutaneous electrical nerve stimulation to the treatment of spasticity.
Analyses of variants of the Ser/Thr dehydratase IlvA provide insight into 2-aminoacrylate metabolism in Salmonella enterica

RidA is a conserved and broadly distributed protein that has enamine deaminase activity. In a variety of organisms tested thus far, lack of RidA results in the accumulation of the reactive metabolite 2-aminoacrylate (2AA), an obligate intermediate in the catalytic mechanism of several pyridoxal 5′-phosphate (PLP)-dependent enzymes. This study reports the characterization of variants of the biosynthetic serine/threonine dehydratase (EC 4.3.1.19; IlvA), which is a significant generator of 2AA in the bacteria Salmonella enterica, Escherichia coli, and Pseudomonas aeruginosa and the yeast Saccharomyces cerevisiae. Two previously identified mutations, ilvA3210 and ilvA3211, suppressed the phenotypic growth consequences of 2AA accumulation in S. enterica. Characterization of the respective protein variants suggested that they affect 2AA metabolism in vivo by two different catalytic mechanisms, both leading to an overall reduction in serine dehydratase activity. To emphasize the physiological relevance of the in vitro enzyme characterization, we sought to explain in vivo phenotypes using these data. A simple mathematical model describing the impact these catalytic deficiencies had on 2AA production was generally supported by our data. However, caveats arose when kinetic parameters, determined in vitro, were used to predict formation of the isoleucine precursor 2-ketobutyrate and model in vivo (growth) behaviors. Altogether, our data support the need for a holistic approach, including in vivo and in vitro analyses, to generate data used in understanding and modeling metabolism.
Application of continuous-time wavelet entropy for detection of cardiac repolarisation alternans

Prognostic utility of microvolt T-wave alternans (TWAs) has been established since its clinical acceptance as markers for malignant ventricular arrhythmias, leading to sudden cardiac death. Accurate detection of TWA from surface electrocardiography is a challenge because of invisible nature of the phenomenon. A novel TWA detection scheme based upon analysis of continuous-time wavelet entropy (CTWE) trend of consecutive ventricular repolarisation complexes is presented. The CTWE is computed using relative wavelet energy coefficients of continuous wavelet transform. Variety of simulated alternan waveforms, wavelet functions, frequency bands and noise levels are used to test the algorithm. The algorithm achieves a sensitivity of 100% at signal-to-noise ratio (SNR) >35 dB for all the selected wavelet functions and sensitivities of 99.5, 97 and 92% for Symlet4, Mexican Hat and truncated Morlet functions, respectively, at 30 dB SNR. A performance improvement of 5 dB is achieved by only computing the wavelet coefficients at the optimal frequency band. This study concludes that CTWE can successfully characterise the heterogeneity of cardiac repolarisation and detect TWA phenomenon.
Feasibility of Sub-Axial Cervical Laminar Screws, Including C7, in the Indian Population: A Study on 50 Patients Using Computed Tomography-Based Morphometry Measurements

Study Design Observational study of computed tomography (CT) data. Purpose We performed a CT-based radiographic analysis of sub-axial cervical lamina in the Indian population to assess the feasibility of laminar screws. Overview of Literature Morphometric studies have been performed for populations of various ethnic groups, but none exist for Indian populations. Methods Cervical spine CT scans of 50 adults with a minimum slice thickness of <2 mm (0.5–2 mm) were obtained from the database of a single center in northern India. Measurements (e.g., length, thickness, and height) were taken in millimeters along the axial, coronal, and sagittal planes. Three measurements were made to assess laminar anatomy, namely, the translaminar/screw length, laminar thickness, and sagittal laminar height. Results The final sample comprised 500 laminae in 50 patients, resulting in 1,500 measurements. The mean translaminar lengths of the C3, C4, C5, C6, and C7 laminae were 19.48 mm, 19.60 mm, 19.61 mm, 20.49 mm, and 22.85 mm, respectively. The mean thick- , 19.60 , 19.60 mm, 19.61 mm, 20.49 mm, and 22.85 mm, respectively. The mean thick- mm, 19.61 mm, 20.49 mm, and 22.85 mm, respectively. The mean thick- , 19.61 , 19.61 mm, 20.49 mm, and 22.85 mm, respectively. The mean thick- mm, 20.49 mm, and 22.85 mm, respectively. The mean thick- , 20.49 , 20.49 mm, and 22.85 mm, respectively. The mean thick- mm, and 22.85 mm, respectively. The mean thick- , and 22.85 mm, respectively. The mean thick , and 22.85 mm, respectively. The mean thicknesses of these cervical laminae were 3.12 mm, 2.62 mm, 2.56 mm, 3.47 mm, and 5.20 mm, respectively. The mean sagittal heights of these laminae were 9.38 mm, 9.80 mm, 10.12 mm, 11.31 mm, and 13.84 mm, respectively. Except for the C7 vertebrae, all other levels had a success rate of <10% in the Indian population using the criteria of a laminar height of at least 9 mm and thickness of 4.5 mm. Limited success was achieved at the C5, C6, and C3 levels. Conclusions To the best of our knowledge, the present study is the only series on the feasibility of laminar screws in the sub-axial cervical spine in the Indian population. We found that Indian patients have smaller anatomical dimensions and thus, are not suitable for laminar screws in the sub-axial cervical spine, barring C7, which is contrary to findings for populations in western and south Asian countries.
Searching for Yield Abroad: Risk-Taking Through Foreign Investment in U.S. Bonds

The risk-taking effects of low interest rates, now prevailing in many advanced countries, "search-for-yield," can be hard to analyze due to both a paucity of data and challenges in identification. Unique, security-level data on portfolio investment into the United States allow us to overcome both problems. Analyzing holdings of investors from 36 countries in close to 15,000 unique U.S. corporate bonds between 2003 and 2016, we show that declining home-country interest rates lead investors to shift their portfolios toward riskier U.S. corporate bonds, consistent with "search-for-yield". We estimate even stronger effects when home interest rates reach a low level, suggesting that risk-taking further accelerates.
Deciphering the transcription factor-microRNA-target gene regulatory network associated with graphene oxide cytotoxicity

Abstract Graphene oxide (GO) has recently emanated as a promising material in cancer treatment. To unveil the underlying mechanisms of microRNAs (miRNAs) and potential target genes involved in GO cytotoxicity, we firstly compiled GO-related miRNAs and genes in human cancer cell lines treated with GO from public databases and published works. Besides miRNAs as post-transcriptional regulators of gene expression, transcription factors (TFs) are also the main regulators at the transcriptional level. In the following, we explored the regulatory relationships between miRNAs, target genes, and TFs. Thereafter, a gene regulatory network consisting of GO-responsive miRNAs, GO-responsive genes, and known human TFs was constructed. Then, 3-node regulatory motif types were detected in the resulting network. Among them, miRNA-FFL (feed-forward loop) was identified as a significant motif type. A total of 184 miRNA-FFLs were found and merged to generate a regulatory sub-network. Pathway analysis of the resulting sub-network highlighted adherens junction, focal adhesion, and TGFβ signaling pathways as the major pathways that previous studies demonstrate them to be the affected pathways in GO-treated cells. Functional investigations displayed that miRNAs might be involved in the control of apoptosis through disruption of cell adhesion in response to cytotoxicity. Moreover, GO-cell interactions can lead to miRNA targeting of genes (i.e. Rac1 and RhoA) involved in the cytoskeleton assembly process. These specific toxic properties support biomedical applications of GO, especially for cancer therapy.
Cytotoxic Effects of Diclofenac on Cervical Cancer Cells in Cell Culture

There are studies showing that NSAIDs including diclofenac may have anticancer effects. This study was carried out to assess the effects of diclofenac on viability of cervical cancer cells (Hela cell line) in cell culture. Hela cells were exposed to 0.0001, 0.001, 0.01, 0.1, 1 and 10 mg/ml of diclofenac solution. MTT assay was used to determine cytotoxic effects of the diclofenac on Hela cells in cell culture. Control Hela cells were not exposed to diclofenac. Our results indicated that administration of 0.1, 1 and 10 mg/ml of diclofenac resulted in significant decrease in viability of Hela cells compared to control cells (P<0.05, P<0.001 and P<0.001). Administration of 0.0001, 0.001 and 0.01 mg/ml of diclofenac did not significantly change viability of Hela cells compared to control group. According to our finding, high doses of diclofenac have cytotoxic effects on cervical cancer cells.
Empowerment of Rural Women in Agriculture: A Socio-psychological Analysis

Abstract Empowerment in woman’s development is a way of defining, challenging and overcoming barriers in her life through which she increases her ability to shape her life. The active, multi-dimensional processes enable them to realize full identity and power in all spheres of life. Rural women play a crucial role in agricultural development and allied fields. However without their total intellectual and physical participation in these activities, it is not possible to achieve the goals of rural uplift. In the present study an attempt has been made to analyze the present status of women empowerment in different caste categories in Sultanpur district of Uttar Pradesh by examining pivotal socio-psychological factors of empowerment such as autonomy vs. dependency, self-esteem vs. self-depreciation and reflective vs. repetitive behavior of women. The results showed that majority of the women had medium or low level of empowerment. Further women who were illiterate/less educated were less empowered and generally belong to the scheduled caste category. In overall terms, the researchers would argue that the broad based approach is one of the best approaches to guarantee gender equity and to empower rural women, and that this approach should be considered in the formulation of rural policies and the creation and implementation of agricultural and rural development programmes and projects.
Role of Phytase Supplementation in Improving Growth Parameters and Mineral Digestibility of Catla catla Fingerlings Fed Moringa by-Products Based Test Diet

A 90-days feeding trial was conducted to determine the influence of phytase on growth and mineral availability to Catla catla fingerlings fed mixture of Moringa oleifera leaf meal (MOLM) and M. oleifera seed meal (MOSM) based diets. Due to the presence of anti-nutritional factors in plant by-products based diets, reduced mineral availability to fish results in poor fish growth performance. Phytase enzyme is beneficial to decrease these anti-nutritional effects of plant based diets. MOLM+MOSM mixture was used to prepare six test diets that were supplemented with graded levels (0, 300, 600, 900, 1200 and 1500 FTU kg) of phytase. Fingerlings were fed at the rate of 4% live wet weight twice a day. On the basis of results it was noted that addition of phytase showed significant (P<0.05) enhancement in bioavailability of minerals, resulting in improved growth performance (weight gain 229%, SGR 1.32 and FCR 1.3). Maximum (ADC%) of minerals was noted at 900 FTU kg level of phytase supplemented MOLM+MOSM based diet. On the basis of these results it was suggested that phytase supplementation at 900 FTU kg level is helpful to develop an eco-friendly and cost effective fish feed by using moringa by-products based diet.
Pediatric Orthogenomics: The Latest Trends and Controversies

The advent of molecular biology has paved way for an era of personalized medicine. Though medical disciplines such as oncology and cardiology are advanced in their use of genomics, implementation has been slower in other specialties, such as orthopaedics. Recent advances in genomic technology have shed light on the underlying genetic basis of various pediatric orthopaedic disorders. Prior understanding of the genetic makeup of a patient may help individualize care in patients with conditions including idiopathic scoliosis, congenital talipes equinovarus and congenital limb deformities. The fastpaced growth of information in orthogenomics often makes it challenging for an orthopaedic surgeon to effectively use this information for patient care. Genetic characterization of a patient will help indicate risk of progression of a condition, recurrence and/or response to a treatment modality, and a collaborative approach between an orthopaedic surgeon and a geneticist can help tailor patient care. The following review article summarizes current understanding in molecular genomics of common pediatric orthopaedic disorders.
Climate change and media usage: Effects on problem awareness and behavioural intentions

This article examines the question of how climate change awareness and media usage are related to each other. An integrated model for explaining awareness of environmental problems and behavioural intentions is developed. The model is then tested using data from a Germany-wide representative survey. In contrast to most previous studies, this investigation focuses not on the effects of selective, topic-specific media usage, but on the differential effects of information usage on multiple dependent variables. The results show that media usage does have a certain influence on awareness of climate problems and on related behavioural intentions, but the results cannot be explained by a simple formula. The findings differ both with respect to the various dependent variables and across different media. The fact that media do not always have a mobilizing, awareness-enhancing effect is certainly one of the most interesting results of this study.
Characterization of the Two-Photon Absorption Carrier Generation Region in Bulk Silicon Diodes

Abstract : The pulsed laser has been a popular experimental method for interrogating single event effects (SEEs) in microelectronic devices and circuits for many years [1]. While particle accelerator testing is still considered to be the standard test method, the expense and availability of particle accelerator facilities suitable for SEE testing can often be limiting factors in thoroughly characterizing devices and circuits. Particle accelerator testing can also be destructive since devices can be exposed to a very high fluence of radiation, potentially resulting in device degradation. In addition to being more readily available and cost effective, laser testing offers deep insight into the spatial and temporal characteristics of SEEs that can be difficult or impossible to determine with broadbeam particle accelerator based test methods. Also, assuming the laser pulse energy is not excessively high, device degradation can be completely avoided. Because of these factors, SEE laser testing is an important resource for the the radiation effects community. SEE laser testing is often performed using laser light wavelengths above the bandgap. In this regime, Beer's law absorption dominates, and it can be assumed that for every one energetic photon incident on the semiconductor, one electron-hole pair will be created [1]. However, one limitation of choosing this approach is that the total laser penetration will exponentially attenuate beginning at the surface of the device under test (DUT). This requires that devices be tested from the topside, through any device overlayer materials that may be present. As metallization densities increase in device overlayers, topside laser testing can become difficult or impossible, due to shadowing effects. This was one limitation of topside laser testing that lead to the development of two-photon absorption (TPA) SEE laser testing [2].
Decolourization of Azo dyes in a two-stage process using novel isolate and advanced oxidation with Hydrogen peroxide / HRP system

Azo dyes, which are aromatic compounds with one or more NQN groups, constitute the largest class of synthetic dyes used in commercial applications (Anjali et al., 2007). These dyes are widely used in a number of industries, such as textile dyeing, food, cosmetics, paper printing, with the textile industry as the largest consumer. All dyes do not bind to the fabric; depending on the class of the dye, its loss in wastewaters could vary from 2% for basic dyes to as high as 50% for reactive dyes, leading to severe contamination of surface and ground waters in the vicinity of dyeing industries (Ganesh et al., 1994; O Neill et al., 1999). Many dyes are visible in water at concentrations as low as 1 mg l. Textile processing wastewaters with dye contents in the range of 10 200 mg l are highly colored. Some of the dyes and their degradation products are carcinogenic in ISSN: 2319-7706 Volume 3 Number 1 (2014) pp. 514-522 http://www.ijcmas. com
Doping suppression and mobility enhancement of graphene transistors fabricated using an adhesion promoting dry transfer process

We present the facile dry transfer of graphene synthesized via chemical vapor deposition on copper film to a functional device substrate. High quality uniform dry transfer of graphene to oxidized silicon substrate was achieved by exploiting the beneficial features of a poly(4-vinylphenol) adhesive layer involving a strong adhesion energy to graphene and negligible influence on the electronic and structural properties of graphene. The graphene field effect transistors (FETs) fabricated using the dry transfer process exhibit excellent electrical performance in terms of high FET mobility and low intrinsic doping level, which proves the feasibility of our approach in graphene-based nanoelectronics.
