Removal of americium from effluent generated during the purification of plutonium by anion exchange
Authors: Noronha Donald M. , Pius Illipparambil C. , Chaudhury Satyajeet
Published: April 2015

Studies have been carried out on removal of americium from the effluent generated during anion exchange purification of
plutonium. Americium 241, generated by the beta decay of Plutonium-241, is the major source of α activity in this highly acidic
effluent and its removal would render the waste easily disposable. A simple and effective co-precipitation method, using thorium
oxalate has been investigated for the treatment of this alpha active aqueous waste. Experiments have been carried out to identify
optimum conditions to obtain high percentage co-precipitation with minimum amount of co-precipitant. Efforts were carried out to
correlate the optimum conditions of co-precipitation of americium obtained in these experiments with solubility of thorium oxalate and
americium oxalate calculated from solubility products of these compounds, stability constants of thorium and americium oxalate
complexes taken from literature. The saturation capacity of thorium oxalate for Am(III) was also calculated by analyzing the
K
d value data using Langmuir adsorption equation. The strong tendency of americium to get co-precipitated and the high
capacity exhibited by thorium oxalate for the uptake of americium indicate feasibility of using this method for the treatment of anion
exchange effluent.

Uranyl tris-(carbohydrazide) nitrate [UO2((N2H3)2CO)3](NO3)2 was prepared by the
reaction of water solution of dioxouranium(VI) nitrate UO2(NO3)2(H2O)6 with ethanol solution of carbohydrazide
(N2H3)2CO in a molar ratio of 1 to 3 in an neutral medium. The substance was characterized by elemental, thermal
analysis and IR and 15N MAS CP NMR spectroscopy. Ab initio crystal structure determination was carried out using X-ray
powder diffraction techniques. The compound crystallizes in monoclinic lattice with unit cell parameters:
a = 15.193(1) Å, b = 12.005(1) Å, c = 10.842(1) Å, β = 109.15(1)○,
V = 1868.11 Å3, Z = 4, SG = Cc. The type of carbohydrazide coordination was additionally confirmed by
15N MAS CP NMR and IR spectroscopy. In the complex ion [UO2((N2H3)2CO)3]2+ three carbohydrazide ligands
coordinate to UO2
2+ through oxygen and nitrogen forming three five-membered chelate rings. The carbohydrazide rings are
tuned to the equatorial plane of complex. The crystal structure consists of zig-zag chains of [UO2((N2H3)2CO)3]2+
cations stretched along c-axis. The cations in the chain are linked by the hydrogen bonds between the cations themselves. The anions
are located in the pores between chains and participate in hydrogen bonding between adjacent chains and additionally link the chain
sections. The length of the chain section is 5.768 Å and the angle between sections is 140○. The
substance [UO2((N2H3)2CO)3](NO3)2 is thermally stable up to 215 ℃ and then decomposes with an
explosion.

Nuclear forensic analysis was conducted on two uranium samples confiscated during a police investigation in Victoria, Australia. The
first sample, designated NSR-F-270409-1, was a depleted uranium powder of moderate purity (∼ 1000 μg/g total
elemental impurities). The chemical form of the uranium was a compound similar to K2(UO2)3O4 · 4H2O. While
aliquoting NSR-F-270409-1 for analysis, the body and head of a Tineid moth was discovered in the sample. The second sample, designated
NSR-F-270409-2, was also a depleted uranium powder. It was of reasonably high purity (∼ 380 μg/g total elemental
impurities). The chemical form of the uranium was primarily UO3 · 2H2O, with minor phases of U3O8 and
UO2. While aliquoting NSR-F-270409-2 for analysis, a metal staple of unknown origin was discovered in the sample. The
presence of 236U and 232U in both samples indicates that the uranium feed stocks for these samples experienced
a neutron flux at some point in their history. The reactor burn-up calculated from the isotopic composition of the uranium is
consistent with that of spent fuel from natural uranium (NU) fueled Pu production. These nuclear forensic conclusions allow us to
categorically exclude Australia as the origin of the material and greatly reduce the number of candidate sources.
Autophagy in Alzheimer’s disease
Authors: Zare-shahabadi Ameneh , Masliah Eliezer , Johnson Gail V.W. , Rezaei Nima
Published: April 2015

Autophagy is a vesicle and lysosome-mediated degradative pathway that is essential for protein homeostasis and cell health. In particular, compared to nonneuronal cells, neurons are dependent on high basal autophagy for survival. There is emerging agreement that defects in autophagy are likely to contribute to the neurodegenerative processes in numerous diseases, including Alzheimer’s disease (AD). Autophagy-lysosome defects occur early in the pathogenesis of AD and have been proposed to be a significant contributor to the disease process. Given the fact that autophagy deficits are likely major contributors to the etiology of AD, the focus of this review will be on recent studies that support a role for autophagy deficits in AD.

Published: April 2015

Laser cladding of the TiAl/Fe+Co-coated WC+TiB2 pre-placed mixed powders on a Ti-6Al-4V alloy substrate can be used to form TiB2/α-W2C-reinforced composite coating, which improved the wear resistance of the substrate. To further improve the TiB2/α-W2C-reinforced composite coating, yttria partially stabilized zirconia (YPSZ) was added into the pre-placed powders. A metallurgical bonding was formed between the YPSZ-infused composite coating and the substrate. Many amorphous alloys were produced in this composite coating due to the action of YPSZ, and such coating showed fine microstructure. Thus, it is feasible to further improve the wear resistance of the laser clad TiB2/α-W2C-reinforced composite coating through the addition of YPSZ.

Published: April 2015

This paper presents a method based on embedding Green’s function into a well-known fixed-point iteration scheme for the numerical solution of a class of boundary value problems arising in mathematical physics and geometry, in particular the Yamabe equation on a sphere. Convergence of the numerical method is exhibited and is proved via application of the contraction principle. A selected number of cases for the parameters that appear in the equation are discussed to demonstrate and confirm the applicability, efficiency, and high accuracy of the proposed strategy. The numerical outcomes show the superiority of our scheme when compared with existing numerical solutions.

The linear and nonlinear stability analysis of the motionless state (conduction solution) and of a vertical throughflow in an anisotropic porous medium are tested. In particular, the effect of a nonhomogeneous porosity and a constant anisotropic thermal diffusivity have been taken into account. Then, the accuracy of the linear instability thresholds are tested using a three dimensional simulation. It is shown that the strong stabilising effect of gravity field. Moreover, the results support the assertion that the linear theory, in general, is accurate in predicting the onset of convective motion, and thus, regions of stability.

Published: April 2015

Prostate cancer (PCa) is the most common malignancy affecting men in the western world. Although radical prostatectomy and radiation therapy can successfully treat PCa in the majority of patients, up to ∼30% will experience local recurrence or metastatic disease. Prostate carcinogenesis and progression is typically an androgen-dependent process. For this reason, therapies for recurrent PCa target androgen biosynthesis and androgen receptor function. Such androgen deprivation therapies (ADT) are effective initially, but the duration of response is typically ≤24 months. Although ADT and taxane-based chemotherapy have delivered survival benefits, metastatic PCa remains incurable. Therefore, it is essential to establish the cellular and molecular mechanisms that enable localized PCas to invade and disseminate. It has long been accepted that metastases require angiogenesis. In the present review, we examine the essential role for angiogenesis in PCa metastases, and we focus in particular on the current understanding of the regulation of vascular endothelial growth factor (VEGF) in localized and metastatic PCa. We highlight recent advances in understanding the role of VEGF in regulating the interaction of cancer cells with tumor-associated immune cells during the metastatic process of PCa. We summarize the established mechanisms of transcriptional and post-transcriptional regulation of VEGF in PCa cells and outline the molecular insights obtained from preclinical animal models of PCa. Finally, we summarize the current state of anti-angiogenesis therapies for PCa and consider how existing therapies impact VEGF signaling.

Published: April 2015

This paper aims at describing teaching and learning activities in chemistry lesson through environmental-based (contextual-based)  experiments that are viewed from the perspective of Islam. Islam teaches its followers to study their environment in order to find solution for many problems. One of the problems posed by chemistry teachers with regards to conducting chemistry experiments is the lack of laboratory equipments. In fact, if environment has been studied well, Islam has provided anything we need including the need to conduct chemistry experiment. Verses in Quran, especially al-Baqarah: 185, an-Nisa: 28, al-Hajj: 78, and Hud: 61 implied that our environment provides more than enough for us to do experiments. The problem of not doing the experiments was that because teachers are not studying their environment well enough. This paper describes some ideas in which environment helps chemistry teachers to be able to conduct chemistry experiments without losing the chemistry concept. DOI: 10.15408/tjems.v1i2.1267

Islamic values should be built in educational institution as early as possible, at least from elementary school. It might be rather difficult to think of Islamic values being taught in the elementary school, especially in social studies subject. One idea was by focusing students learning process on the development of certain values, such as, wealthiness, fairness, honesty, responsibility, and prohibition of practicing usury. Educating the students with those values were believed to contribute to the development of Islamic values in later age. This paper provides some ideas within which the mentioned values were taught in elementary school. DOI: 10.15408/tjems.v1i2.1268

Authors: Kessler David , Pusic Martin , Chang Todd P. , Fein Daniel M. , Grossman Devin , Mehta Renuka , White Marjorie , Jang Jaewon , Whitfill Travis , Auerbach Marc ,   for the INSPIRE LP investigators
Published: April 2015

BACKGROUND AND OBJECTIVE:

Simulation-based skill trainings are common; however, optimal instructional designs that improve outcomes are not well specified. We explored the impact of just-in-time and just-in-place training (JIPT) on interns’ infant lumbar puncture (LP) success.

METHODS:

This prospective study enrolled pediatric and emergency medicine interns from 2009 to 2012 at 34 centers. Two distinct instructional design strategies were compared. Cohort A (2009–2010) completed simulation-based training at commencement of internship, receiving individually coached practice on the LP simulator until achieving a predefined mastery performance standard. Cohort B (2010–2012) had the same training plus JIPT sessions immediately before their first clinical LP. Main outcome was LP success, defined as obtaining fluid with first needle insertion and <1000 red blood cells per high-power field. Process measures included use of analgesia, early stylet removal, and overall attempts.

RESULTS:

A total of 436 first infant LPs were analyzed. The LP success rate in cohort A was 35% (13/37), compared with 38% (152/399) in cohort B (95% confidence interval for difference [CI diff], −15% to +18%). Cohort B exhibited greater analgesia use (68% vs 19%; 95% CI diff, 33% to 59%), early stylet removal (69% vs 54%; 95% CI diff, 0% to 32%), and lower mean number of attempts (1.4 ± 0.6 vs 2.1 ± 1.6, P < .01) compared with cohort A.

CONCLUSIONS:

Across multiple institutions, intern success rates with infant LP are poor. Despite improving process measures, adding JIPT to training bundles did not improve success rate. More research is needed on optimal instructional design strategies for infant LP.

Authors: Pratap Jayant “Nick” , Varughese Anna M. , Mercurio Patti , Lynch Terri , Lonnemann Teresa , Ellis Andrea , Rugg John , Stone W. Ray , Bedinghaus Cindi
Published: April 2015

BACKGROUND AND OBJECTIVES:

Cancelation on the day of surgery (DoSC) represents a costly wastage of operating room (OR) time and causes inconvenience, emotional distress, and financial cost to families. A quality improvement project sought to reduce lost OR time due to cancelation.

METHODS:

Key drivers of the process included effective 2-way communication with families, compliance with fasting rules, and decision-making on patient illness before the day of surgery. A multidisciplinary team conducted serial tests of change addressing the various key drivers. Interventions were simplified, colorful, personalized preoperative instruction sheets and text-message reminders to caregivers’ cellphones, as well as a defined institutional decision-making pathway to permit rescheduling before the day of surgery in case of patient illness concerns. After initial smaller-scale testing, the interventions were implemented across all patients and sites. Data were collected from the hospital information technology system and analyzed by using control charts and statistical process control methods.

RESULTS:

Mean OR time lost due to DoSC was decreased from a baseline of 5.7 to 3.6 hours/day in testing with a subset of surgical services at the hospital’s base campus, and then from 6.6 hours to 5.5 hours/day when implemented across all services at both surgical sites.

CONCLUSIONS:

By applying quality improvement methods, significant reductions were made in time lost due to DoSC. The impact can be significant by improving institutional resource utilization.
Case Report of Successful Treatment of Pallid Breath-Holding Spells With Glycopyrrolate
Authors: Williams Jason , Cain Nicole
Published: April 2015

Breath-holding spells are a common childhood disorder that typically present before 12 months of age. Whereas most cases are benign, some patients have very severe cases associated with bradycardia that can progress from asystole to syncope and seizures. Treatment studies have implicated the use of several therapies, such as oral iron, fluoxetine, and pacemaker implantation. This is a retrospective study of patients treated with glycopyrrolate for pallid breath-holding spells. Clinical data from 4 patients referred to pediatric cardiology who saw therapeutic benefit from treatment using glycopyrrolate were reviewed to evaluate for clinical response to the drug. Two twin patients, whose symptoms began at 5 months of age, experienced a decrease in breath-holding frequency after 1 month. A patient diagnosed at 7 months of age experienced a decrease in frequency of spells. A patient diagnosed at 10 months of age reported cessation of syncope shortly after initiation of glycopyrrolate and complete resolution of breath-holding spells during prolonged treatment. This case study of 4 patients with pallid breath-holding offers evidence that glycopyrrolate may be beneficial in treating breath-holding spells and has a safer side-effect profile than pacemaker implantation.
Alcohol Use in Films and Adolescent Alcohol Use
Authors: Waylen Andrea , Leary Sam , Ness Andrew , Sargent James
Published: April 2015

OBJECTIVES:

To investigate whether exposure to alcohol use in films (AUFs) is associated with early alcohol use, binge drinking, and alcohol-related problems in British adolescents.

METHODS:

Cross-sectional study with 5163 15-year-olds from the Avon Longitudinal Study of Parents and Children in the United Kingdom. We measured adolescent exposure to AUFs, age at onset of alcohol use, and binge-drinking behavior. We adjusted for early childhood social, family and behavioral factors, adolescent tobacco use, and peer drinking.

RESULTS:

After adjustment, adolescents with the highest exposure to AUFs were 1.2 (95% confidence interval [CI]: 1.1–1.3) times more likely to have tried alcohol compared with those least exposed and 1.7 (95% CI: 1.5–2.0) times more likely to binge drink. They were 2.4 (95% CI: 1.9–3.1) times more likely to drink weekly and 2.0 (95% CI: 1.7–2.4) times more likely to have alcohol-related problems than those least exposed.

CONCLUSIONS:

Exposure to AUFs is associated with higher risk of alcohol use and alcohol-related problems in UK adolescents. Our findings provide evidence to support the argument that a review of film-rating categories and alcohol ratings for all films may help reduce problem-related alcohol consumption in young people.

Introduction: Laboratory diagnosis of pheochromocytoma-paraganglioma syndrome has been markedly improved during the past two decades. Aim: Retrospective assessment of diagnostic utility of urinary catecholamines and their metabolites as well as serum chromogranin A in 155 patients diagnosed at the 2nd Department of Medicine, Semmelweis University. Method: Urinary catecholamines and metabolites were measured using high-performance liquid chromatography with electrochemical detection in 155 patients with pheochromocytoma-paraganglioma (of whom 28.4% had hereditary background) and in 170 non-pheochromocytoma patients used as controls. Serum chromogranin A was measured by immunoradiometry. Results: Sensitivity (93.2%) and specificity (87.0%) of urinary fractionated metanephrines were higher than those of urinary catecholamines (90.9% vs. 85.7%, respectively) and serum chromogranin A (88.7% and 77.5%, respectively). Urinary normetanephrine and serum chromogranin A correlated positively with tumor size (r = 0.552, p<0.0001 and r = 0.618, p<0.0001, respectively). Conclusions: These data confirm the diagnostic utility of urinary catecholamines and their metabolites. Urinary normetanephrine and serum chromogranin A may help to estimate tumour mass and probably tumour progression. Orv. Hetil., 2015, 156(16), 626–635.

Authors: Szűcs Viktória , Szabó Erzsébet , Bánáti Diána
Published: April 2015

Introduction: Nowadays the number of people suffering from different non-communicable diseases is continuously rising. However, the risk of the incidence of these diseases can be reduced with the help of conscious and healthy lifestyle. Aim: The main aim of the study was to explore Hungarian consumers’ attitude related to healthy diet. Method: A questionnaire survey was conducted with 473 respondents. Results: According to the participants it is difficult to make head or tail of information about healthy nutrition, and the “Internet” is the most frequently used source of information. With cluster analysis 3 significantly different consumer groups were identified: participants of the “ambitious” group show positive attitude towards healthy diet; the “health conscious” cluster cares about and actively supports health and diet; and members of the “indifferent” cluster are less interested and do not make a remarkable effort for their healthy diet. Conclusions: Results of the questionnaire survey pointed out the importance of targeted information to relevant consumer groups, as well as the importance of popularization of accurate and reliable information sources. Furthermore, presentation and popularization of cost-effective healthy nutrition are of outstanding importance, especially for consumers in need (e.g. elderly, low-income people). Orv.

The role of β-blockers in patients with metabolic syndrome and hypertension
Authors: Dézsi Csaba András
Published: April 2015

The choice of treatment of patients with hypertension should not be based solely on the blood pressure value, because the risk of cardiovascular diseases are influenced by the presence and magnitude of other risk factors, too. The presence of a metabolic disease (diabetes mellitus, metabolic syndrome) itself categorizes the patient as a high risk individual. In such cases the use of combined treatment is usually considered. For example, in case of hypertension aggraviated by left ventricular dysfunction, ischaemic heart disease or cardiac insufficiency, β-blocker treatment is usually included in the combination of the first setting.

Potential value of energy storage in the UK electricity system
Authors: Teng Fei , Pudjianto Danny , Strbac Goran , Brandon Nigel , Thomson Alan , Miles John
Published: April 2015

This paper assesses the value of distributed energy storage and informs the business case for its multiple applications in the UK electricity system. In contrast to earlier studies that focus on the benefits of energy storage for system operation and development, this work analyses the value that it may deliver to the owner. For this purpose, three models are proposed and applied to analyse the benefit of energy storage with applications in energy and ancillary service markets, revenue maximisation in the context of feed-in tariffs and reduction of carbon dioxide emissions. A large set of studies is carried out to quantify the commercial and emissions benefits of energy storage for those applications. Sensitivity analysis across various scenarios is performed to understand the key drivers for the value of energy storage and how it is affected by energy storage parameters and other factors such as network constraints, prices of energy and ancillary services, and inherent energy system characteristics. A review of current and near-term storage technology costs and functionality is also presented.
Seismic structure–soil–structure interaction between pairs of adjacent building structures
Authors: Knappett J.A. , Madden P. , Caucis K.
Published: April 2015

Structure–soil–structure interaction between adjacent structures, which may occur in densely populated urban areas, has received little attention compared to the soil–structure interaction of single isolated structures. Additionally, recent earthquakes in/near such areas (e.g. the Christchurch series, 2010–2011) have shown that large motions can be followed by strong aftershocks. In this paper, the seismic behaviour of isolated structures and pairs of adjacent structures under a sequence of strong ground motions has been investigated using a combination of centrifuge and finite-element modelling. The latter utilised an advanced constitutive model that can be parameterised from routine test data, making it suitable for use in routine design. The finite-element models were shown to accurately simulate the centrifuge-measured response (in terms of surface ground motion and structural sway, settlement and rotation) even after multiple strong aftershocks, so long as the buildings' initial conditions were reproduced accurately. For the case of a building structure with a close neighbour, structural drift and co-seismic settlement could be reduced or increased as a result of structure–soil–structure interaction, depending chiefly on the properties of the adjacent structure. This suggests that careful arrangement of adjacent structures and specification of their properties could be used to control the effects of structure–soil–structure interaction. In all cases where adjacent structures were present, permanent rotation (structural tilt) was observed to increase significantly, demonstrating the importance of considering structure–soil–structure interaction in assessing the seismic performance of structures.

This paper describes a study conducted to evaluate the use of concrete containing up to 100% recycled concrete aggregate (RCA) for the construction of a commercial building known as the Samwoh Eco-Green Building in Singapore. The study is a continuation of research which established that concrete produced with RCA can achieve strength comparable to that of normal concrete produced with natural aggregate for structural applications by using a rational mix design approach. The present study was carried out to evaluate the effects of RCA on other engineering and durability properties of concrete, including compressive strength, flexural strength, tensile splitting strength, creep strain, water permeability, initial surface absorption, chloride ingress and sulfate resistance. With normal concrete serving as the basis for comparison, the experimental data showed that comparable compressive strength, flexural strength and tensile splitting strength were attainable for concrete containing up to 100% RCA. Although concrete with 100% RCA exhibited higher creep strain and initial surface absorption rate as well as lower resistance to water permeability, chloride ingress and external sulfate attack, the effects on the concrete performance are insignificant. On the whole, the research study suggests that RCA concrete can be designed to meet the specifications for structural applications, which led to the successful completion of the Samwoh Eco-Green Building.

Published: April 2015

Buscou-se mostrar, através deste estudo, pela utilização da psicanálise, como se organiza o espaço em Godbout e como a aporia constituída por este espaço é pretensamente resolvida por uma espécie de auto-anulação representada pela imobilidade e pelo desejo de retorno ao útero.On a essayé, dans cette étude, par l'utilization de la psychanalyse, de montrer comment s'organise l'espace chez Godbout et comment l'aporie constituée par cet espace est faussement résolue par une sorte d'auto-anéantissement représenté par l'immobilité et par le désir de retour à l'utérus.

O diário do outro
Authors: Gotlib Nádia Battella
Published: April 2015

A produção literária de Simone de Beauvoir marca-se pelo seu caráter acentuadamente autobiográfico. E também por manter aí um constante diálogo com o seu companheiro Sartre. Sob esta perspectiva, A Cerimônia do Adeus (1981), que relata os dez últimos anos de vida de Sartre, apresenta uma estrutura narrativa curiosa: propõe-se como um diário, mas do outro, pois a narradora tenta anular-se em favor da reconstrução de um retrato de Sartre. No entanto, por injunção desta proposta, inviável, o texto acaba transformando-se num ponto de convergência de vários gêneros narrativos, tendo em vista o caráter múltiplo de personalidade do biografado. E este personalizado trabalho narrativo, à revelia da própria autora, acarreta o processo inverso: o texto transforma-se num retrato de Simone. Consuma-se, desta forma, no próprio corpo do texto, o movimento de sedução, em que ambos, homem e mulher, realizam-se como sujeitos necessários Um ao Outro.L'oeuvre de Simone de Beauvoir est marquée par son caractère fortemente autobiographique, aussi bien que par le dialogue constante avec son partenaire Sartre. Sous une telle optique, La Cérémonie des Adieux (1981), qui raconte les dix dernières années de la vie de Sartre, présente une structure narrative curieuse: le livre se présente comme un journal, mais le journal de l'autre, puisque la narratrice essaie de s'effacer face à la reconstruction d'un portrait de Sartre. Pourtant, à cause de cet objectif inacessible, le texte finit par devenir un point de convergence de plusieurs genres de récit, étant donné le caractère multiple de la personnalité du sujet de la biographie. Ce travail narratif personnalisé va entraîner le processus inverse, malgré son auteur même: le récit devient un portrait de Simone. Ainsi, c'est dans le corps même du texte qu'a lieu le mouvement de séduction où homme et femme se réalisent comme sujets indispensables l'Un à l'Autre.
