Analysis of flow through cylindrical packed beds with small cylinder diameter to particle diameter ratios

The wall effect is known to present difficulties when attempting to predict the pressure drop over randomly packed beds. The Nuclear Safety Standard Commission, “Kerntechnischer Ausschuss” (KTA), made considerable efforts to develop an equation which predicts the pressure drop over cylindrical randomly packed beds consisting of mono-sized spheres. The KTA was able to estimate a limiting line, which defines the region for which the wall effect is negligible, however the theoretical basis for this line is unclear. The goal of this investigation was to determine the validity of the KTA limiting line, using an explicit approach. Packed beds were generated using Discrete Element Modelling (DEM), and the flow through the beds simulated using Computational Fluid Dynamics (CFD). STAR-CCM+ R © was used for both DEM and CFD operations, and the methods developed for this explicit approach were validated with empirical data. The KTA correlation predictions for friction factors were compared with the CFD results, as well as the predictions from a few other correlations. The KTA correlation predictions for friction factors did not correspond well with the CFD results at low aspect ratios and low modified Reynolds numbers, due to the influence of the wall effect. The KTA limiting line was found to be valid, but not exact. A new limiting line for the KTA correlation was suggested, however the new limiting line improved little on the existing line and was the result of some major assumptions. In order to improve the determination of the position of the KTA limiting line further, criteria need to be established which determine how small the error in predicted friction factor must be before the KTA correlation can be accepted as accurate.
Single Row Rotator Cuff Repair: A Retrospective Study of 40 Cases

Purpose: Purpose of the study is to report functional outcomes of arthroscopic single row rotator cuff repair in patients with rotator cuff tear. Type of study: Retrospective study. Materials and methods: This retrospective study was conducted at Vaishvi orthopaedic hospital on 40 patients aged between 40 years to 73 years with rotator cuff tear, treated with arthroscopic single row rotator cuff repair between July 2013 to January 2017. Diagnosis was based on true AP radiograph and magnetic resonance imaging of affected shoulder. Patients were followed up for minimum of 6 months with mean follow up of 15.84 months. Pre and post operative rehabilitation protocols were given equal importance with compulsory minimum 4 months post operative rehabilitation and physiotherapy. The results and outcomes were assessed with the use of constant shoulder score and WORC (Western Ontario Rotator Cuff) index. Factors affecting the functional outcomes were also evaluated. Results: During the period between July 2017 to January 2017 No patient was lost to follow up. In our series of 40 patients with mean age of 56.275, 65% (n=26) patients had traumatic injury and 35% (n=14) patients had degenerative cuff tear. The AFF according to constant score improved from average 71.80 degree preoperatively to 168.70 degree post operatively at minimum 6 months follow up. Average WORC index at the end of follow up was around 89%. Results are evaluated with constant shoulder score and WORC index showing statistically significant improvement in postoperative functional outcome. Conclusion: Arthroscopic single row rotator cuff repair is effective in improving the functional status of shoulder in patients with rotator cuff tear.
The structure of the Coenagrion mercuriale populations in the New Forest, southern England

The damselfly Coenagrion mercuriale (Charpentier) is a poor disperser and susceptible to habitat fragmentation/loss. It is protected by European legislation. An analysis of Capture-Mark-Recapture (CMR) data indicated that the population network on Beaulieu Heath in the New Forest comprised some 40 000 individuals. A nationwide genetic study indicates that the New Forest is a principal reservoir of genetic diversity for UK C. mercuriale. The New Forest is, however, presently best characterised as five genetic units. We found that several small, isolated populations of C. mercuriale in the New Forest showed substantial genetic differentiation from the principal populations on Beaulieu Heath, Setley Plain and Mill Lawn Brook. Isolation is bought about by preventing dispersal across intervening areas of unsuitable habitat such as forest, farmland or road. Although habitat loss is a principal concern for the persistence of this species, the pattern of limited movement to proximate sites highlights the need for a network of suitable habitat patches. This will also help to slow the rate of genetic erosion at peripheral sites.
Programmed cell death in Entamoeba histolytica induced by the aminoglycoside G 418

Received 11 April 2007 Revised 21 June 2007 Accepted 7 August 2007 This study presents morphological and biochemical evidence of programmed cell death (PCD) in Entamoeba histolytica induced by exposure of trophozoites to the aminoglycoside antibiotic G418. Morphological characteristics of PCD, including cell shrinkage, reduced cellular volume, nuclear condensation, DNA fragmentation and vacuolization were observed, with preservation of trophozoite membrane integrity. PCD is orchestrated biochemically by alterations in intracellular ion fluxes. In G418-treated trophozoites, overproduction of reactive oxygen species (ROS), decreased intracellular K, increased cytosolic calcium, and decreased intracellular pH levels were observed. However, externalization of phosphatidylserine was not detected. These results suggest that amoebae can undergo PCD under stress conditions, and that this PCD shares several properties with PCD reported in mammals and in a variety of unicellular organisms.
Inhibition of Osteopontin Synthesis in THP-1 Cells Stimulated with Phorbol 12-Myristate 13-Acetate by Brefelamide Derivatives

Plasma osteopontin (OPN) levels are elevated in mycobacterium tuberculosis patients and may involve granuloma formation. New inhibitors using brefelamide, an aromatic amide isolated from Dictyostelium cellular slim molds which may inhibit OPN transcription at concentration of 1M, were synthesized as compounds C, D and E. Their inhibitory activity against OPN synthesis in phorbol 12-myristate 13-acetate (PMA)-stimulated THP-1 cells was confirmed using enzyme-linked immunosorbent assay (ELISA), a multicolor immune-fluorescent microscope and western blot analysis. For the ELISA performed using the full-length OPN, each compound showed significant inhibition. Detailed analysis were done using C and D. They also showed inhibitory activity when used on another ELISA system to detect the immune-related form of OPN and their IC50 were 0.6 and 1.2 M for compounds C and D, respectively. Fluorescent particle count of stained cell numbers by O-17 showed the inhibition. Antibodies for O-17 and 34E3, which recognize OPN N-terminus and thrombin-cleaved site, respectively, detected distinct bands on the western blots following PMA stimulation. The decrease in full-length OPN detected by O-17 in the compound-treated cells was identified via western blot analysis. These newly-developed compounds may therefore be used in clinical trials for cancer and infectious diseases.

The results in this paper establish that information contained in patents in a technological domain is strongly correlated with the rate of technological progress in that domain. The importance of patents in a domain, the recency of patents in a domain and the immediacy of patents in a domain are all strongly correlated with increases in the rate of performance improvement in the domain of interest. A patent metric that combines both importance and immediacy is not only highly correlated (r = 0.76, p = 2.6*10) with the performance improvement rate but the correlation is also very robust to domain selection and appears to have good predictive power for more than ten years into the future. Linear regressions with all three causal concepts indicate realistic value in practical use to estimate the important performance improvement rate of a technological domain.
Age Differences In Emotional Response To Future Events

Much prior research has been conducted on how emotions change across the life span. The current study aimed to determine age differences in emotional responses to future events by utilizing Linguistic Inquiry Word Count (LIWC) software to determine the quantitative usage of anxiety related words by both younger and older adults when speaking about common future events. All participants (n= 107) were asked to share three neutral past events and three neutral possible future events. These narratives were analyzed via LIWC. Prior research shows that younger adults tend to experience more worry about the future than older adults. According to the socioemotional selectivity theory, positive and negative processing biases are a product of time perspective. Furthermore, the discrete emotions theory of aging predicts that older adults experience an increase in sadness due to uncontrollable losses. Individual correlations of anxiety related words use for past and future events were not statistically significant. However, follow-up t-tests on anxiety related word usage in young, middle-aged, and older adults, found that younger adults used more anxiety related words when speaking about the future as compared to older adults. Older adults, however, used more anxiety related words when speaking about the past than middle-aged adults.
Korea's Trade, Growth of Trade and the World Economy in Post-Crisis ASEAN+3 Free Trade Agreement: An Econometric and Policy Analysis

The Korean economy had achieved economic 'miracles' in the past, but it currently faces many challenges, economically and politically (Tran Van Hoa, 2002), compounded by a global economic slowdown with hesitant recovery (IMF, 2004), terrorist attacks, regional wars, the SARS and avian flu outbreaks in Asia, and domestic and global uncertainty ahead. The paper introduces the extended gravity theory to construct a simple flexible simultaneous-equation econometric model of Korea trade and growth with its major trading partners, and provides efficient empirical results on its trade-growth causality and trade determination over the past two decades. Based on these findings, economic policy challenges are then targeted for study and solution development.
Understanding the nature of oil fluctuations using 1 neutral network moving average: A study on the returns of crude oil futures

This paper describes the profitability of technical trading rules which are enhanced by the use of neural networks on crude oil futures contracts traded on Chicago Merchantile Exchange and on Bursa Derivative Malaysia. The profitable returns on the futures contract on crude light oil futures traded from 2/1/2008 to 31/12/2014 offer a piece of evidence on the ability of technical trading rules using neural networks to outperform the threshold benchmark, buy and hold. The results here suggest that it is worthwhile to design, build and develop more robust, machine learning algorithms like neural networks enhanced moving average technical indicator to enhance portfolio returns. The conclusion drawn is that neural network can be used in technical analysis as a predictor for futures market prices.
Evaluation of Effect of Education on parental anxiety before and after of voiding cystourethrogram

Voiding cystourethrogram is the golden test for diagnosis of bladder reflax to ureter. Increase of anxiety has interference with ability of parents for helping to children. Our study was done with goal of taking an appropriate intervention for decrease of anxiety on parents of children that have VCUG. Our study is one-side blind clinical trial. Standard questionnaire of Spielberger before and after of VCUG in the both groups was completed with this different that in the case group necessary explanation about VCUG given to parents significant level of study was 0.05 and data was analyzed with spss18. Frequency of state anxiety after VCUG with separation of groups was: in the case group 3.5% of parents have mild anxiety, 45.9% moderate and 1.2% severe anxiety.in the control group 9.4% have mild anxiety, 37.6 moderate and 2.4% severe anxiety. No significant different watch between groups. (P Value = 0.194). The result of this study shoe that explanation about VCUG can not decrease anxiety of parents.
J un 2 01 2 Gamma-ray Burst Host Galaxies as Probes of Galaxy Formation and Evolution

Host galaxies are an excellent means of probing the natal env ironments that generate gammaray bursts (GRBs). Surveys of long-duration GRB (LGRB) host environments and their ISM properties have produced intriguing new results with impor tant implications for LGRB progenitor models. These host studies are also critical in evaluating t he u ility of LGRBs as potential tracers of star formation and metallicity at high redshifts, partic ularly when considering the implications for properties of host galaxies above z ∼ 6. I will summarize our group’s latest research on LGRB host galaxies, and discuss the resulting impact on our under standing of these events’ progenitors, energetics, afterglow properties, and cosmological appli cations.
The Comparative Effect of Collaborative Strategic Reading and Content-Based Instruction on EFL Learners' Reading Comprehension

The present study was an attempt to compare the effect of teaching Collaborative Strategic Reading (CSR) and Content-Based Instruction (CBI) on the reading comprehension of English as a Foreign Language (EFL) learners. To fullfill this objective, a group of 90 intermediate female EFL learners, within the age range of 17 to 19, took a piloted sample of the PET as a pre-treatment proficiency test. Sixty of them were selected as homogeneous learners and were randomly divided into two experimental groups of CSR and CBI. The CSR group receieved CSR strategy training based on Klingner, Vaughan, and Schumm's model (2001), while the CBI group receieved CBI-based strategy training, using Tsai and Shang's (2010) model. At the end of the training, another piloted PET reading test was administered as the posttest. The pre-treatment reading scores were analyzed using the Mann-Whitney U test whose results confirmed the pre-treatment homogeneity of the participants. The post-treatment scores were also analyzed using the Mann-Whitney U test whose results indicated no significant difference in the reading posttest levels of CBI and CSR groups, U = 423.5, z = -. 401, p = . 688, r = -. 0517. The article concludes with a discussion on the results and presenting some implications.
Intrinsic and emergent anomalies at deconfined critical points

It is well known that theorems of Lieb-Schultz-Mattis type prohibit the existence of a trivial symmetric gapped ground state in certain systems possessing a combination of internal and lattice symmetries. In the continuum description of such systems the Lieb-Schultz-Mattis theorem is manifested in the form of a quantum anomaly afflicting the symmetry. We demonstrate this phenomenon in the context of the deconfined critical point between a Neel state and a valence bond solid in an $S =1/2$ square lattice antiferromagnet, and compare it to the case of $S=1/2$ honeycomb lattice where no anomaly is present. We also point out that new anomalies, unrelated to the microscopic Lieb-Schultz-Mattis theorem, can emerge prohibiting the existence of a trivial gapped state in the immediate vicinity of critical points or phases. For instance, no translationally invariant weak perturbation of the $S = 1/2$ gapless spin chain can open up a trivial gap even if the spin-rotation symmetry is explicitly broken. The same result holds for the $S =1/2$ deconfined critical point on a square lattice.
Traditional Needling Techniques as Practical Constructions from Reading Historical Descriptions

In 2009 I published in two parts the first of a series of papers on acupuncture ‘Filling the whole in acupuncture’ [6]. I am still working on the other papers in that series. The 2009 paper described a traditional supplementation needling technique from the Toyohari system of acupuncture and then explored historical and modern ideas about how to model what might be happening with the needling technique.
A General Hermitian Nonnegative-Definite Solution to the Matrix Equation AXB = C

We derive necessary and sufficient conditions for the existence of a Hermitian nonnegative-definite solution to the matrix equation AXB = C. Moreover, we derive a representation of a general Hermitian nonnegative-definite solution. We then apply our solution to two examples, including a comparison of our solution to a proposed solution by Zhang in [1] using an example problem given from [1]. Our solution demonstrates that the proposed general solution from Zhang in [1] is incorrect. We also give a second example in which we derive the general covariance structure so that two matrix quadratic forms are independent.
Effect of d-fenfluramine on the indole contents of the rat brain after treatment with different inducers of cytochrome P 450 isoenzymes

The effects of pretreatment with inducers of hepatic cytochrome P450 isoenzymes (phenobarbital, dexamethasone and /~-naphthoflavone) on the metabolism of d-fenfluramine (d-F) and its acute and long-lasting indole-depleting effects were studied in rats, in an effort to obtain further information on the importance of hepatic drug metabolism in relation to its neurochemical actions. Twenty-four hours after the last dose of each inducer, rats were injected with d--F hydrochloride (5 mg/kg, IP) and killed at various thnes thereafter for parallel determination of indoles and drug concentrations in plasma and brain. Additional rats were treated as above and killed 1 week after d-F hydrochloride (5 and 10 mg/kg) to study the recovery of indole in the cortex, a particularly sensitive brain area. Phenobarbital and /~-naphthoflavone and, to a lesser degree, dexamethasone, stimulated the metabolism of d-F, as evidenced by a decrease in plasma and brain areas under the curve (AUC) compared to vehicle-treated rats. This indicated that multiple isoenzymes are capable of mediating the drug's metabolism, primarily by N-dealkylation to d-norfenfluramine (d-NF). None of the inducers raised plasma and brain AUC of the nor-derivative, and in fact phenobarbital and particularly /~-naphthoflavone reduced it. These different effects were even apparent in rats given d-NF (2.5 mg/kg), indicating that both phenobarbital and ]~-naphthoflavone also stimulate the sequential metabolism of the nor-metabolite (by N-deamintaion) which, however, is apparently enhanced most actively by/~-naphthoflavone-inducible forms of P-450. Total "active" brain concentrations (d-F + d-NF) after the different pretreatments were in the order of/~-naphthoflavone < phenobarbital < dexamethasone <_ vehicle. Interestingly, /~-naphthoflavone rapidly reversed the depletion of brain indoles caused by d F (and d-NF); M. Anelli C. Fracasso A. Bergami • A. Ferrarese • S. Garatt ini S. Caccia ( ~ ) Istituto di Ricerche Farmacologiche "Mario Negri", Via Eritrea 62, 1-20157 Milan, Italy phenobarbital provided partial protection and dexamethasone did not appreciably modify either the acute or long-term neurochemical effects of the drug. The fact that phenobarbital affected d N F kinetics tess than/3-naphthoftavone, and provided only partial protection against the acute and long-lasting neurochemical effects of high doses of d-F, further stresses the critical role of d -NF in the neurochemical outcome of its parent drug. These findings support the view that the degree and duration of the indole-depleting effects are related to critical brain concentrations of the parent compound and its nor-derivative, and provide indirect evidence that hepatic metabolites other than d-NF are unlikely to play any role in the neurochemical effects of high doses of d-F in rats.
Interface Characterization of Current-Perpendicular-to-Plane Spin Valves Based on Spin Gapless Semiconductor Mn2CoAl

Employing the first-principles calculations within density functional theory (DFT) combined with the nonequilibrium Green’s function, we investigated the interfacial electronic, magnetic, and spin transport properties of Mn2CoAl/Ag/Mn2CoAl current-perpendicular-to-plane spin valves (CPP-SV). Due to the interface rehybridization, the magnetic moment of the interface atom gets enhanced. Further analysis on electronic structures reveals that owing to the interface states, the interface spin polarization is decreased. The largest interface spin polarization (ISP) of 78% belongs to the MnCoT-terminated interface, and the ISP of the MnMnT1-terminated interface is also as high as 45%. The transmission curves of Mn2CoAl/Ag/Mn2CoAl reveal that the transmission coefficient at the Fermi level in the majority spin channel is much higher than that in the minority spin channel. Furthermore, the calculated magnetoresistance (MR) ratio of the MnCoT-terminated interface reaches up to 2886%, while that of the MnMnT1-terminated interface is only 330%. Therefore, Mn2CoAl/Ag/Mn2CoAl CPP-SV with an MnCo-terminated interface structure has a better application in a spintronics device.
Critical Review—Identifying Critical Gaps for Polymer Electrolyte Water Electrolysis Development

Although polymer electrolyte water electrolyzers (PEWEs) have been used in small-scale (kW to tens of kW range) applications for several decades, PEWE technology for hydrogen production in energy applications (power-to-gas, power-to-fuel, etc.) requires signiﬁcant improvements in the technology to address the challenges associated with cost, performance and durability. Systems with power of hundreds of kW or even MWs, corresponding to hydrogen production rates of around 10 to 20 kg/h, have started to appear in the past 5 years. The thin ( ∼ 0.2 mm) polymer electrolyte in the PEWE with low ohmic resistance, compared to the alkaline cell with liquid electrolyte, allows operation at high current densities of 1–3 A/cm 2 and high differential pressure. This article, after an introductory overview of the operating principles of PEWE and state-of-the-art, discusses the state of understanding of key phenomenadeterminingandlimiting performance,durability,andcommercialreadiness, identiﬁes important‘gaps’inunderstanding and essential development needs to bring PEWE science & engineering forward to prosper in the energy market as one of its future backbone technologies. For this to be successful, science, engineering, and process development as well as business and market development need to go hand in hand. ©
Analyzing cyclic patterns in psychological data: A tutorial

A growing number of studies on psychological phenomena employ the Ecological Momentary Assessment (EMA) method for obtaining intensive longitudinal data in daily life. Whereas cyclic processes may underlie different psychological and physiological outcomes, the cyclic model that describes such processes is rarely used for fitting EMA data. The aim of this paper is to introduce the cyclic model to researchers, and to demonstrate its use in an empirical data set. It is shown how the cyclic terms can be incorporated in multilevel models. Based on secondary analyses on an existing EMA data set, it can be concluded that adding cyclic terms in EMA analyses may improve model fit and may help understanding the dynamic processes.
