Modelling of the Dissolution of Silicate Glasses by a Monte-Carlo Code (ETCH)
Authors: Dran J-C. , Langevin Y. , Doorhyee E. , Petit J-C.
Published: June 2019

A Monte-Carlo code has been developed to infer dissolution rates of silicate glasses from their chemical composition. The glasses are considered as solid solutions of oxides and silicates, being divided into elementary cells of network formers, in which network modifiers can be incorporated. The different types of cells are randomly distributed and a resistance capacity to dissolution is assigned to each cell. We have tested the case where each cell is removed in a constant time as soon as it is in contact with the solution and a second one where each cell is dissolved in a time depending on the number of already dissolved neighbor cells. The first hypothesis leads to a percolation threshold when the proportion of fast etching cells reaches 25 %. Above, the dissolution front progresses via contiguous channels of fast etching cells. In the second hypothesis the variations of the etch rate with the proportions of each component are much closer to a linear combination of individual etch rates. These predictions have been successfully compared to experimental data on different series of silicate glasses of increasing complexity. Such a treatment could be straightforwardly extended to nuclear glasses.
Long-Term Corrosion Behavior of Copper-Base Materials in a Gamma-Irradiated Environment
Authors: Yunker Wlyne H. , Glass Robert S.
Published: June 2019

The U. S. Department of Energy is currently evaluating the feasibility of using copper-base materials for the manufacture of nuclear waste con- tainers. One site under consideration for geologic disposal of nuclear waste is at Yucca Mountain, Nevada. One feature of this waste repository will be the initial presence of ionizing gamma radiation at high dose rates, which may alter the corrosive medium. To evaluate such effects, three copper-base materials (pure copper, 7% aluminum-copper and 30% nickel-copper) have been exposed (presgntly up to 14 months) to a gamma radiation field of approxi- mately 1 × 104 roentgens/hr. The exposure environments have been: 1) both groundwater (regional to the repository site, although taken from a lower elevation) at 95°C; 2) the water-vapor saturated air phase above it; and 3) air/water vapor at 150°C. In addition to uniform corrosion, both pitting and crevice corrosion have been observed. Characterization of the corrosion layers by X-ray diffraction has shown the presence of mixed copper(I) and copper(II) oxides. Studies by Auger Electron Spectroscopy (AES) have also been conducted in order to further characterize the compositions and structures of these corrosion products.

X-ray absorption spectroscopy has been used to investigate the Ta LIII and LI absorption edges of metamict and annealed pyrochlore minerals A1-2B2O6Y0-1. The LIII edge absorption spectra exhibit a pronounced doublet in primary absorption resonance for the annealed samples which have the pyrochlore structure. The doublet in the LIII edge resonance becomes less pronounced and for some samples even merges Into a singlet for the samples in the unannealed, fully damaged (metamict) state. The LIII edge resonance of the damaged samples closely resembles Ta205 or disordered manganotantalite (MnTaNbO6 ), while the LIII edge resonance for the annealed samples most closely resembles the synthetic pyrochlore KTaWO6·H20. These results are supported by the Ta LIIIedge x-ray absorption data. Fourier transforms of the Ta LIII edge x-ray absorption fine structure (EXAFS) show first neighbor Ta-0 bond lengths of 1.96 ± 0.05 A for the samples in the annealed and metamict state.

The complex structure of Ta205 is used as a model for the Ta-containing oxygen polyhedra in metamict pyrochlores, as it embodies some of the topologic features consistent with the reduction of long-range periodicity with increasing alpha-decay dose: 1) greater distortion of the primary coordination shell around Ta, 2) slightly increased mean second nearest-neighbor  distances, and 3) a wider distribution of second nearest-neighbor distances. These modifications are incorporated in a large unit cell with a b translation of 40 A.

Published: June 2019

Results are presented of physical measurements on candidate buffer materials for use in nuclear fuel waste disposal. The materials being considered as constituent elements of engineered barriers are essentially calcium smectite clays, in other terms swelling clays, coming from fourteen french deposits. The criteria for good candidates are mainly: smectite content in the clay materials, carbonate and organic material content and bulk density of the material, compacted under a pressure of 100 MPa.
Elastic Constants and Graphitic Grain Boundaries of Nanocrystalline CVD-Diamond Thin Films: Resonant Ultrasound Spectroscopy and Micromechanics Calculation
Authors: Ogi Hirotsugu , Nakamura Nobutomo , Tanei Hiroshi , Ikeda Ryuji , Hirao Masahiko , Takemoto Mikio
Published: June 2019

Using resonant-ultrasound spectroscopy coupled with laser-Doppler interferometry, we determine the independent elastic constants of nanocrystalline CVD-diamond thin films with thickness between 2-12 μm. They are deposited on oriented monocrystal silicon substrates by the hot-filament methane/nitrogen CVD method. The diagonal components of the elastic constants are smaller than those of microcrystalline CVD diamond films and bulk diamond. However, the off-diagonal component is larger. We attribute these observations to the presence of sp2-bonded graphitic phase at grain boundaries. A micromechanics model assuming inclusions of thin graphitic plates consistently explains the observations.

Authors: Vellinga W.P. , Timmerman R. , Tijum R. van , De Hosson J.Th.M.
Published: June 2019

The propagation of crack fronts along a PET-glass interface is illustrated. The experimental set-up consists of an Asymmetric Double Cantilever Beam in an optical microscope. Image processing techniques used to isolate the crack fronts are discussed in some detail. The fronts are found to propagate inhomogeneously in space and time, in forward bursts that spread laterally along the front for some distance. In some cases the forward movement of a crack can be almost entirely due to the lateral movement of forward steps (analogous to “kinks”) along the crack front.
Strain and Grain Size Effects on Epitaxial PZT Thin Films
Authors: Blanco Oscar , Heiras Jesus
Published: June 2019

Epitaxial ferroelectric thin films of lead zirconium-titanium oxide, Pb(Zr0.53Ti0.47)O3 (PZT), were successfully grown on SrTiO3, LaAlO3, and Sr(Nb)TiO3 single crystal substrates by a modified RF sputtering technique at high oxygen pressures. The structural properties of the films were evaluated by θ/2θ, ω and ø scans. From these data the crystalline orientation relationships may be extracted. For films grown on SrTiO3 and Sr(Nb)TiO3 substrates, the following orientation relationships were determined: PZT [001] parallel to [001] of the substrate, and PZT [100] parallel to [100] of the substrate. Films grown on LaAlO3 substrates showed a bi-domain crystalline structure with orientation relationships as follows: PZT [100] parallel to [001] of the substrate and PZT [001] parallel to [001] of the substrate. This work was focused to the determination the strain and grain size coefficients, and the analysis of their contribution on the peak broadening in the XRD patterns, and in considering their effects over the ferroelectric behavior. From Williamson-Hall plots, it was possible to conclude that the enhancement of the crystalline film properties (epitaxy and single crystalline domains) reduce the short range strains contribution to peak broadening. On other hand, the grain size contribution to peak broadening was increased with the enhancement of the film cristallinity.
Micro/Nano Indentation and Micro-FTIR Spectroscopy Study of Weathering of Coated Engineering Thermoplastics
Authors: Gupta Samik , Lohmeijer Jan , Sebastian Savio , Preschilla Nisha , Biswas Amit
Published: June 2019

A novel combination of depth-sensing nano-indentation, micro-indentation and micro-FTIR techniques is employed towards understanding the durability of coating layers used on engineering thermoplastics upon exposure to harsh weathering environments. This combination of techniques enables study of changes in surface-to-bulk properties in the clearcoat-substrate system upon weathering; typically observed as a degradation starting from the surface and then proceeding inwards to the bulk of the material. Nano-indentation measurements carried out to understand the mechanical properties of the coating layer provide insights into the changes in hardness and modulus upon prolonged weathering exposure. Depth-sensing micro-indentation and micro-FTIR spectroscopy studies performed to evaluate mechanical performance and chemical changes, respectively, explain the influence of the substrate on the coating layer, especially at the interface upon weathering. This unique combination of depth-sensing indentation and micro-FTIR spectroscopy has led to an understanding of the properties of the coating layer and the substrate individually as well as an integral system as a function of weathering exposure time. Finally, the physico-chemical properties of the coating and substrate are linked to performance prediction, enabling optimization of coating-substrate combinations.
Experiments on the Elastic Size Dependence of LPCVD Silicon Nitride
Authors: Ren Yuxing , Lam David C. C.
Published: June 2019

Recent experimental observations showed significant elastic size effects in small scales. While surface stress theories are used to describe nanometer scale size effects, strain gradient theories describe size effect observed in micron sized epoxy. Size effects in single crystalline silicon and epoxy make it unclear whether there is size dependence of the elastic behaviors of widely used LPCVD silicon nitride thin films in submicron scale. In this paper, submicron thick LPCVD silicon nitride beams were fabricated and bending tests were conducted on the beams. Results showed fluctuating normalized bending rigidities in the beams with different thickness. XPS and XRD analyses were used to analyze the material consistency of the beams. The fluctuations maybe related to varying crystalline phase fractions in the thin films. The beams were annealed and bending tests were conducted to investigate possible correlation between the fluctuations and crystalline phase fractions. Results showed similar level of fluctuations in normalized bending rigidities before and after annealing while XRD results of the annealed films showed increase in crystalline phase fractions for all thicknesses. While LPCVD silicon nitride may have size dependence in the nanometer scale, size dependence of normalized bending rigidity of LPCVD silicon nitride appears to be insignificant in submicron scale.

Published: June 2019

Intrinsic stresses due to lattice mismatch and high densities of threading dislocations and extrinsic stresses resulting from the mismatch in the coefficients of thermal expansion are present in almost all III-Nitride heterostructures. Stress relaxation in the GaN layers occurs in conventional and in pendeo-epitaxial films via the formation of additional misfit dislocations, domain boundaries, elastic strain and wing tilt. Polychromatic X-ray microdiffraction, high resolution monochromatic X-ray diffraction and finite element simulations have been used to determine the distribution of strain, dislocations, sub-boundaries and crystallographic wing tilt in uncoalesced and coalesced GaN layers grown by maskless pendeo-epitaxy. An important parameter was the width-to-height ratio of the etched columns of GaN from which the lateral growth of the wings occurred. The strain and tilt across the stripes increased with the width-to-height ratio. Tilt boundaries formed in the uncoalesced GaN layers at the column/wing interfaces for samples with a large ratio. Sharper tilt boundaries were observed at the interfaces formed by the coalescence of two laterally growing wings. The wings tilted upward during cooling to room temperature for both the uncoalesced and the coalesced GaN layers. It was determined that finite element simulations that account for extrinsic stress relaxation can explain the experimental results for uncoalesced GaN layers. Relaxation of both extrinsic and intrinsic stress components in the coalesced GaN layers contribute to the observed wing tilt and the formation of sub-boundaries.
Balancing railway network availability and engineering access
Authors: Armstrong John , Preston John
Published: June 2019

As traffic on Britain's railways has grown, the system is approaching capacity and moving towards 24/7 operation. This increases wear and tear, and reduces access for maintenance, renewal and enhancement. Increasing costs of renewals and enhancements are also questioned, amid funding scarcity. Alongside predictive and preventive maintenance, improved planning and implementation of renewals and enhancements are needed, balancing network availability for train operations with cost-effective construction activities. Typically, extended track possessions maximise construction efficiency but also reduce network availability for operations, whereas short possessions maintain network availability but are least efficient for construction purposes. The effects of infrastructure activities on network availability have typically been monitored and assessed retrospectively, rather than being planned proactively to maximise network availability or to optimise the trade-offs between network availability and engineering efficiency. This paper reviews the current situation and identifies opportunities to enhance planning processes and the balance between network availability and engineering efficiency.
LNG as an energy efficient eco-friendly cryogenic fuel
Authors: Sarkar S C
Published: June 2019

The use of an old fuel in a new form has progressed at a rapid space for the last couple of years, due to its several advantages. The fuel in question is natural gas and, its new form, is liquefied natural gas designated as LNG. LNG transported in cryogenic vessels offers several advantages over pipe line transport of natural gas when the gas consuming areas are far away from the gas producing areas. Moreover, LNG as an automobile fuel has also a definite edge over other fuel. However, the LNG age in India is of very recent origin and, only in January, 2004, the first LNG cargo had reached an Indian port in the state of Gujarat. In this juncture, this paper presents an effective study on the characteristics of LNG, advantages and disadvantages of various natural gas liquefaction cycles, the present state of affairs of LNG in India, its import and CNG versus LNG as an automobile fuel, eco-friendliness of natural gas fuel etc. It also discusses the potential of natural gas generation from different sources, and the need for indigenous development of LNG technology for import substitution in the Indian context.

Published: June 2019

This paper aims at analyzing the energy management activities for commercial buildings of a financial service company in South Africa by energy efficiency in terms of performance, operation, equipment and technology (POET). The sustainability of a general energy management program is discussed within this POET framework. As an application of this discussion to the commercial building scenario, the award winning energy management program of this financial service group company is featured from the POET perspective of energy efficiency. The case study shows that the POET based framework can not only cover all major energy management activities, but also identify further energy efficiency improvement opportunities.

Published: June 2019

This paper analyses wind speed characteristics and wind power potential of Port Elizabeth using statistical Weibull parameters. A measured 5–minute time series average wind speed over a period of 5 years (2005 - 2009) was obtained from the South African Weather Service (SAWS). The results show that the shape parameter (k) ranges from 1.319 in April 2006 to 2.107 in November 2009, while the scale parameter (c) varies from 3.983m/s in May 2008 to 7.390 in November 2009.The average wind power density is highest during Spring (September–October), 256.505W/m2 and lowest during Autumn (April-May), 152.381W/m2. This paper is relevant to a decision-making process on significant investment in a wind power project.

Authors: Chetty Leon , Ijumba Nelson
Published: June 2019

One of mankind’s greatest modern challenges is poverty alleviation. The provision of electricity can greatly assist in this regard. The tapping of small amounts of power from an HVDC transmission line represents a solution to this problem especially in rural areas. This paper analyses the dynamic characteristics of a parallel-cascaded tapping station. The results obtained clearly indicate that the parallel-cascaded tapping station proves to be a viable solution to tapping small amounts of power from an HVDC transmission line.
A qualitative study of the optimal control model for an electric power generating system
Authors: Aderinto Yidiat O. , Bamigbola Mathias O.
Published: June 2019

The economic independence of any nation depends largely on the supply of abundant and reliable electric power and the extension of electricity services to all towns and villages in the country. In this work, the mathematical study of an electric power generating system model was presented via optimal control theory, in an attempt to maximize the power generating output and minimize the cost of generation. The factors affecting power generation at minimum cost are operating efficiencies of generators, fuel cost and transmission losses, but the most efficient generator in the system may not guarantee minimum cost as it may be located in an area where fuel cost is high. We choose the generator capacity as our control ui(t), since we cannot neglect the operation limitation on the equipment because of its lifespan, the upper bound for ui(t) is choosing to be 1 to represent the total capability of the machine and 0 to be the lower bound. The model is analyzed, generation loss free equilibrium and stability is established, and finally applications using real life data is presented using one generator and three generator systems respectively.

Published: June 2019

Background. It is important to minimize time and cost of physician surveys while still achieving a reasonable response rate. Mixed-mode survey administration appears to improve response rates and decrease bias. A literature review revealed physician response rates to mixed-mode surveys averaged about 68%. However, no identified studies used the combination of e-mail, fax, and telephone. The purpose of this study was to evaluate physician response rates based on surveys first administered by e-mail, then fax, then telephone. Methods. Surveys initially were administered by e-mail to 149 physicians utilizing SurveyMonkey©. Two follow-up reminder e-mails were sent to non-respondents at two-week intervals. Surveys then were faxed to physicians who had not responded. A follow-up fax was sent to non-respondents one week later. Finally, phone interviews were attempted with physicians who had not responded by e-mail or fax; each physician was called at least twice. Results. Of the 149 eligible physicians, 102 completed the survey for a response rate of 68.5%. Of those who responded, 49 (48%) responded by e-mail, 25 (24.5%) by fax, and 28 (27.5%) by phone. Mode of response did not differ by gender, specialization, or years in practice. In addition, mode of response was not related to the primary study question, physician willingness to use text messaging for immunization reminders. Conclusions. This mix of survey methodologies appeared to be a feasible combination for achieving physician responses and may be more cost effective than other mixed methods.

Published: June 2019

Background. Obesity is a chronic disease of epidemic proportions. Primary care providers are on the front line of diagnosing and treating obesity and need better tools to deliver top-notch obesity care. Methods. A pilot randomized trial was conducted to test a chronic care model (CCM) program for obesity compared to usual care. Primary care patients, 18 years and older, with a body mass index (BMI) between 27 and 45 were enrolled. Sixteen weekly 90-minute group office visits were structured with the first 30 minutes encompassing individualized clinical assessments and the final 60 minutes containing the group-based standardized intensive lifestyle training. The primary outcome was weight change at 16 weeks. Secondary outcomes were weight change at 24 weeks, change in diet and physical activity behaviors, self-efficacy for weight control behaviors, and physiologic markers of cardiovascular risk at 16 and 24 weeks. Results. The participants (19 in the active arm and 10 in the control arm) were 49.8 ± 11.5 years old (mean ± SD), 97% women, 55% white, and 41% black. Weight change in the control arm at week 16 was 0.25+ 2.21 kg (mean + SD) and that for the active arm was -5.74 + 4.50 kg (n=16). The difference between the two arms was significant (p = 0.0002). Both the intent-to-treat analysis using the last observation carried forward approach and the analysis including completers only provided similar siginificant results. Conclusions. This study demonstrated that a CCM program incorporating group office visits was feasible and effective for obesity treatment in primary care settings.
Observations of Pre-operative Teamwork and Communication During the Implementation of a City-Wide Surgical Safety Checklist
Authors: Hansen Terry Leonid , Goerl Kyle , Fears Reginald , Nguyen Tim , Hart Traci , Uhlig Paul
Published: June 2019

BACKGROUND: Use of the World Health Organization's (WHO) perioperative safety checklist has been shown in prior studies to reduce morbidity and mortality. In 2009, the Medical Society of Sedgwick County, Kansas, developed a modified version of the WHO checklist for city-wide implementation. This study evaluated how the checklist was used at a Wichita hospital. METHODS: An observational tool was developed to evaluate time-outs at the beginning of surgical procedures. A convenience sample of cases was evaluated across surgical specialties and procedures. Observations included: 1) when the time-out was done, 2) who led the time-out, 3) which items on the checklist were addressed, 4) how much time was spent, and 5) whether problems were identified or adverse events prevented. RESULTS: Data were collected from 121 observations. Only one of the surgical teams was observed to refer directly to the checklist posted in the OR to conduct their time out. The time-out was done before induction (3%), drape (19%), incision (77%), and after incision (1%). The process was led by the circulating nurse (92%), surgeon (7%), and circulating nurse and surgeon together (1%). The percent of completed checklist items was: patient identity (96%), procedure (96%), antibiotics (87%), site (80%), allergies (75%), position (70%), equipment (60%), DVT prevention (50%), images (40%), surgeon concerns (36%), and anesthesia provider concerns (34%). On average, seven (SD = 2.5) of 11 items on the checklist were addressed. Time spent ranged from less than one minute to five minutes; 78% took one minute or less. Problems were identified in 7% of cases. In one case, a wrong site surgery was prevented. CONCLUSIONS: Despite the intention to implement a city-wide surgical safety checklist, the checklist rarely was used in its entirety to conduct the observed time-outs in the subject hospital. Although the checklist was under-utilized, safety benefits were observed from the time-out process. These would likely be enhanced and extended by consistent use of a checklist.

Published: June 2019

Background. The purpose of this study was to quantify the prevalence of cancer patients utilizing social support services while undergoing treatment and to identify patient and clinical factors associated with utilization of such services. Methods. This was a cross-sectional study. Surveys were distributed to three cancer clinics at 11 locations in the greater Kansas City metropolitan area in 2010. Study inclusion criteria included being at least 18 years old and undergoing treatment for cancer at the time of survey completion. Results. A total of 465 oncology patients completed surveys. Two-thirds (67.5%, n = 314) were undergoing treatment for cancer and were included in the final analysis. More than half (63.7%, n = 198) were female, and the average age was 58.9 ± 13.3 years. More than one-third (37.4%, n = 117) reported using cancer-related social support services. Additionally, 22% (n = 69) reported not using support services but were interested in learning more about those services. Patients had increased odds of having used support services if they were female (OR = 2.67; 95% CI = 1.47, 4.82), were younger adults, or had stage I-III (OR = 2.67; 95% CI 1.32, 5.26) or stage IV cancer (OR = 2.3; 95% CI 1.14, 4.75) compared to those who did not know their cancer stage. Conclusions. More than one-third of patients reported using social support services. A substantial portion of participants reported not using support services but were interested in learning more about those services. Increasing social support service utilization might be especially important to explore for men, those who do not know their cancer stage, and older adults.
Comparative Effectiveness and Safety of Empiric Ampicillin plus Gentamicin or Empiric Piperacillin-Tazobactam in the Neonatal Intensive Care Unit
Authors: Smith Irina , Ahlers-Schmidt Cari , Bloom Barry T
Published: June 2019

BACKGROUND: This study was designed to assess piperacillin tazobactam (PT) as an alternative to ampicillin and gentamicin (AG) in neonates with suspected systemic infection. METHODS: A retrospective, unmatched population of AG (2007-2009) and PT (2009-2012) exposed infants were evaluated for initial effectiveness, adverse events, and subsequent morbidities or mortality. Data included gestational age, birth weight, sex, Apgar score, length of hospital stay, glomerular filtration rate for days 1 and 2, duration on mechanical ventilation, duration on oxygen therapy, incidence of sepsis (blood or cerebrospinal fluid culture positive), incidence of ventilator associated pneumonia, and incidence of necrotizing enterocolitis. All positive blood cultures during the study period were reviewed. Data about specific microorganisms and sensitivity to antibiotics were RESULTS: No significant differences in demographics or initial Apgar scores were noted. There were no significant differences in systemic rash or diaper rash. PT was associated with higher glomerular filtration rate on day two. Four infants had early onset sepsis with ampicillin resistant E. coli. One of these, in the PT group, had intermediate sensitivity to gentamicin as well. CONCLUSION: Use of PT as the initial empiric antibiotic was not associated with increased adverse outcomes. The challenge of ampicillin resistant Escherichia coli should encourage others to consider this change.

Published: June 2019

Background. Human papillomavirus (HPV) vaccination is recommendedfor all adolescents aged 11 to 12 years, but coveragein Kansas is exceptionally poor. To understand local coverage, receiptof the 3-dose HPV vaccine series among pediatric patients atthe University of Kansas Medical Center (KUMC) was evaluated.

Methods. All patients aged 11 to 12 years who were seen by aKUMC primary care provider (family medicine and pediatrics)in 2013 were included in the retrospective chart review. Recordswere reviewed through December 31, 2014 to capture the numberof HPV doses received, and receipt of other recommendedvaccines (tetanus-diphtheria-pertussis and meningococcal conjugate).Pearson’s chi-squared tests were used to evaluate relationshipsbetween HPV vaccination and patient characteristics.

Results. Of the 261 eligible females and 243 eligible males, 71.2%received ≥ 1 HPV vaccine dose, 55.2% received ≥ 2 doses, and39.3% completed the HPV vaccine series (3 doses). Although vaccineinitiation was slightly lower in males compared to females(67.1% vs. 75.1%, p = 0.047), no difference in vaccine completionwas seen between males and females (37.0% vs. 41.7%, p = 0.319).Over 80% of patients received other concurrently recommendedvaccines (Tdap: 81.7%, meningococcal: 81.3%). HPV series completionoccurred more often among Spanish-speaking femalescompared to English-speaking females (59.5% vs 37.7%; p < 0.01).Conclusions. The proportion of adolescents who received theHPV vaccination at KUMC is substantially higher than nationaland state estimates, but there is room for improvement forboth initiation and series completion.

Second Generation Patient Specific Total Knees Demonstrate a Higher Manipulation Rate Compared with “Off-the-shelf” Implants
Authors: Haeder Paul R. , Chong Alexander C.M. , Bhargava Tarum
Published: June 2019

Introduction. Patient specific total knee arthroplasty (TKA) theoreticallyprovides a more accurate fit to the native knee but mayhave difficulty achieving full range of motion (ROM) post-operatively.Post-operative ROM data were compared between patientswho underwent cemented patient-specific cruciate-retaining(PSCR) and standard cemented posterior-stabilized (SPS) TKAs.

Methods. PSCR and SPS TKAs that were performed from January2014 to September 2015 by the same surgeon using the same postoperativeprotocols at two selected facilities were reviewed. Twoandsix-week post-operative ROM data were obtained and thenumber of patients with knee flexion less than 110° was recorded.

Results. Twenty-one patients in the PSCR group and 57 patientsin the SPS group were included. The percentage of patientswith knee flexion less than 110° was similar in both groups preoperatively(10% vs 14%, p = 0.60) and two-week post-operatively(57% vs 68%, p = 0.35). However, at six-week post-operativelythere was significant difference (29% vs 7%, p = 0.01).

Conclusions. These results provide evidence to alert orthopaedicsurgeons when using these patient specific implants versus conventionalTKA methods. Patients whose TKA was performed usingpatient specific cutting guides struggled to obtain 110° of kneeflexion. Close monitoring, aggressive physical therapy, and earlymanipulation are recommended when using patient specific cuttingguides and custom total knee implants. Further evaluation ina larger group of patients is warranted. KS J Med 2016;9(4):88-92.

Common bean (Phaseolus vulgaris L.) is the most important edible food legume in the world. It represents 50% of grain legumes consumed worldwide. It is a rich source of protein, complex carbohydrates, poly unsaturated fatty acids (linoleic acid and lenolenic acid), fibre, vitamins and minerals. So far as, minerals are concerned, they are not only important for plant growth and development but for animal growth and development spatially humans as well. In present study, we have evaluated 84 genotypes of common bean for various mineral elements and we have observed wide variation in mineral contents and have also identified the genotypes with high mineral contents. The presence of variability in mineral content among the genotypes could be used as an asset by plant molecular breeders for biofortification of common bean which in turn can be used to address the problem of malnutrion in developing and under developed countries, where common bean is a major source of protein.

Authors: Sousa Ana Maria Viola de
Published: June 2019

Dom Bosco, fundador das Congregações Salesianas, desenvolveu um sistema educacional humanitário, no qual a ênfase principal era a pedagogia da vivência e do trabalho, tendências que são observadas nas práticas educativas propostas pela Pedagogia Social. Amorevolezza como afeto e sentimento de amor, pode ser traduzida nas atitudes relacionais entre gerações. Ancorada na ludicidade, a educação de idosos embasada na pedagogia social, além de propiciar a vivência em ambiente mais sociável, estimula também a incorporação de novos saberes necessários à transformação da realidade social do idoso, na busca pela melhor qualidade de vida.AbstractEducational principles of Don Bosco and Social Pedagogy: possible dialogues in the elderly educationDon Bosco, founder of the Salesian Congregation, developed a humanitarian educational system, in which the main emphasis was the pedagogy of experience and labor, trends that are observed in educational practices proposed by the Social Pedagogy.

Conhecimento e a sua socialização na educação escolar para a pedagogia da autonomia de Paulo Freire
Authors: Pena Anderson dos Anjos Pereira , Zientarski Clarice
Published: June 2019

Este artigo visa compreender a visão de Paulo Freire acerca do conhecimento sistematizado e sua socialização na escola, na obra Pedagogia da autonomia: saberes necessários à prática educativa. (FREIRE, 2016a). O fio condutor da análise será a ontologia, pois é a partir da compreensão do nascedouro do homem enquanto ser social e a serviço do processo de humanização por ele idealizado, que Freire explicita sua visão sobre o conhecimento e desenvolve sua teoria pedagógica, sustentando-se em uma base teórica de inspiração existencialista cristã e na filosofia humanista moderna da educação, conforme esclarece Saviani (2008). Neste prisma, tomando por referência a Pedagogia histórico-crítica, sistematizada a partir obras de Saviani (2013) Duarte, (2016) e Martins (2013), entre outros teóricos caberá neste artigo uma comparação entre o sentido do conhecimento para pedagogia da autonomia e para a Pedagogia histórico-crítica. Nossa tentativa aqui é de capturar a essência do pensamento de Freire (2016a) sobre conhecimento, para compreender até que ponto a sua teoria poderá contribuir para criar uma condição irreversível, superior e revolucionária de humanização.

Authors: Wormack Leah , Blum Brice , Bailes Benjamin , Nathaniel Thomas
Published: June 2019

Background. Specific clinical risk factors that may be associated with ambulatory outcome following thrombolysis therapy in ischemic stroke patients with pre-stroke depression is not fully understood. This was investigated. Methods. Multivariate analyses were performed to identify predictors of functional ambulatory outcomes. Patient demographics and clinical risk factors served as predictive variables, while improvement or no improvement in ambulatory outcome was considered as the primary outcome. Results. A total of 595 of these patients received rtPA of which 310 patients presented with pre-stroke depression, 217 had no improvement in functional outcome, while 93 patients presented with an improvement in functional outcome. Carotid artery stenosis (OR= 11.577, 95% CI, 1.281 – 104.636, P=0.029) and peripheral vascular disease (OR= 18.040, 95% CI, 2.956-110.086, P=0.002) were more likely to be associated with an improvement in ambulation. Antihypertensive medications (OR= 7.810, 95% CI, 1.401 –43.529, P=0.019),previous TIA (OR= 0.444, 95% CI, 0.517 –0.971, P=0.012), and congestive heart failure (OR= 0.217, 95% CI, 0.318 –0.402, P=0.030) were associated with a no improvement in ambulation. Conclusion. After adjustment for covariates, more clinical risk factors were associated with no improvement when compared with improvement in functional outcome following thrombolysis therapy in an acute ischemic stroke population with pre-stroke depression.

Published: June 2019

A study was made of the possibility of using natural materials (vermiculites, zeolite) and wastes (ash from the Partizansk Coal-Burning Power Plant) as sorbents in geochemical barriers to manage discharges (technogenic waters) from abandoned coal mines and reduce metal concentrations to established, acceptable standards. Vermiculite from the Kovdor deposit was shown to reduce the concentrations of Fe, Co, Ni, Cu, and Zn cations, in both direct and inverse soil column models, by between two and five times.
Cost economics in construction of multi storied buildings
Authors: Radhakrishnan S. , Selvan K.G.
Published: June 2019

India is fast moving forward from agrarian economy to Industrial Economy. Our country is considered to be a safe platform for industrial investment by the world. Global Leaders and very many MNCs (Multi-National Companies) are evincing keen interest in having Joint Venture or opening their manufacturing facility in India.  India is witnessing a boom in industrialisation. This leads to vast employment opportunities to people of all walks of life. People are moving from rural areas to urban areas for occupational needs. This leads to mass arrival of people to city and consequently the rental costs also shoot up substantially. The industrial wage structure being reasonable with assured disposable income, people who prefer to stay in city start comparing rental costs versus paying EMI towards owning an apartment for themselves. The idea gets strong rooted with the easily available institutional finance to people, especially to youngsters with longer duration of EMI. All these result in a sustained demand for apartments. The builders, particularly in the city, are cashing in on the opportunity by embarking upon construction of multi storied buildings in the city and also the outskirts of same.

Authors: Thiagarajan M , Somasundaram E
Published: June 2019

Field experiments were conducted to develop the suitable organic farming package for rice-blackgram crop sequence. Treatments consisting green manure @6.25 t ha-1+split application of vermicompost @ 4t ha-1 in four equal splits (basal, AT,PIand F) + Panchagavya @ 3% as foliar spray twice (AT and PI) recorded significantly high number of tillers and highest plant height, dry matter production, root length, root volume and root dry weight over rest of the treatments. The recommended practice also recorded relatively, more number of tillers,leaves hill-1, higher plant height, dry matter production, root length, root volume and root dry weight which is on par with the aforesaid treatment.Therefore the application of green manure @6.25 t ha-1+split application of vermicompost @ 4t ha-1 in four equal splits (basal, AT, PI and F) + Panchagavya @ 3% as foliar spray twice (AT and PI) can be recommended for adoption in organic cultivation of rice- black gram crop sequence grown organically.
