An Anti-Imperialist Feminist's Tale
Authors: Baxandall Rosalyn Fraad
Published: September 2015

Roberta Salper, Domestic Subversive: A Feminist Take on the Left, 1960–1976 (Tucson: Anaphora Literary Press, 2014), 236 pages, $20, paperback.
Since second wave feminism is the largest social movement in the history of the United States, it is surprising that there are fewer than a dozen autobiographies written by the activists of the late 1960s and early '70s. Roberta Salper's Domestic Subversive is a welcome addition, especially because it is well-written, often with humor, and promises an anti-imperialist feminist analysis.… Domestic Subversive is a feminist's take on a range of organizations of the left from 1960 to 1976: the student movement in Spain, New Left movement in the United States, Marxist-Leninist Puerto Rican Socialist Party in the United States and Puerto Rico, and a prestigious liberal think tank in Washington, D.C., the Latin American Unit of the Institute of Policy Studies (IPS), where she worked as a Resident Fellow.

Hypoxia-Induced Programmed Cell Death in Root-Tip Meristematic Cells of Triticum aestivum L.
Authors: Pang Nan , Zhang Feixiong
Published: September 2015

In this study, wheat (Triticum aestivum L.) roots were treated with hypoxic water. The staining of cell preparations with DAPI revealed morphological changes of the cells such as nuclear condensation, deformation and fragmentation. Under TEM, cellular membrane shrinkage and breakage, chromatin condensation and apoptotic-like bodies were displayed. The number of mitochondria increased dramatically; their cristae were damaged; the interior became a cavitation and only some flocculent materials were distributed. Indirect immunofluorescence staining indicated that cytochrome C diffused from mitochondria to nucleoplasm and cytoplasm. TUNEL positive nuclei indicated double strand breaks of DNA. DAB staining was used for the identification of hydrogen peroxide and examination showed that the longer the treating time, the darker the staining of the meristematic zones of the roots which suggested the increased accumulation of these Reactive Oxygen Species (ROS). The elevation of hydrogen peroxide production was paralleled with the increase of SOD and POD activities. A negative correlation between the exposure time under hypoxia and the contents of soluble proteins was found. No obvious effect of hypoxia on MDA was established. The obtained results demonstrate that hypoxia causes programmed cell death in the root-tip meristematic cells of Triticum aestivum L. which is most probably attributed to the accumulation of large amounts of ROS.
The Alleviation of the Adverse Effects of Salt Stress in the Tomato Plant by Salicylic Acid Shows A Time- and Organ-Specific Antioxidant Response
Authors: Tari Irma , Csiszár Jolán , Horváth Edit , Poór Péter , Takács Zoltán , Szepesi Ágnes
Published: September 2015

In the last decade contradictory results have been published as to whether exogenous salicylic acid (SA) can increase salt stress tolerance in cultivated plants by inducing an antioxidant response. Salt stress injury in tomato was mitigated only in cases when the plant was hardened with a high concentration of SA (~10−4 M), low concentrations were ineffective. An efficient accumulation of Na+ in older leaves is a well-known response to salt stress in tomato plants (Solanum lycopersicum cv. Rio fuego) but it remains largely unexplored whether young and old leaves or root tissues have a distinct antioxidant status during salt stress after hardening with 10−7 M or 10−4 M SA. The determination of superoxide dismutase (SOD) and catalase (CAT) activity revealed that the SA-induced transient increases in these enzyme activities in young leaf and/or root tissues did not correlate with the salt tolerance of plants. Salt stress resulted in a tenfold increase in ascorbate peroxidase (APX) activities of young leaves and significant increases in APX and glutathione reductase (GR) activities of the roots hardened with 10−4 M SA. Both total ascorbate (AsA) and glutathione pools reached their highest levels in leaves after 10−7 M SA pre-treatment. However, in contrast to the leaves, the total pool of AsA decreased in the roots under salt stress and thus, due to low APX activity, active oxygen species were scavenged by ascorbate non-enzymatically in these tissues. The increased GR activities in the roots after treatment with 10−4 M SA enabled plants to enhance the reduced glutathione (GSH) pool and maintain the redox status of AsA under high salinity, which led to increased salt tolerance.
Surface Waxes as a Plant Defense Barrier Towards Grain Aphid
Authors: Wójcicka Agnieszka
Published: September 2015

The electrical penetration graph (EPG) method was used to quantify the effect of surface waxes on probing behaviour of the grain aphidSitobion avenaeF. (Hemiptera: Aphididae). The experiments showed that wax removal significantly affected probing behaviour ofS. avenae. Generally, the aphids feeding on the plants without wax had a shortened non-probing (EPG-pattern np) and prolonged penetration of peripheral tissues – epidermis and mesophyll (EPG-pattern C). The EPG tests also showed that the three tested extracts of surface waxes from waxy plants RAH 122 were active as aphicides against the grain aphid.
Do Environmental Regulations Increase Bilateral Trade Flows?
Authors: Tsurumi Tetsuya , Managi Shunsuke , Hibiki Akira
Published: September 2015

The argument that stringent environmental regulations are generally thought to harm export flows is crucial when determining policy recommendations related to environmental preservation and international competitiveness. By using bilateral trade data, we examine the relationships between trade flows and various environmental stringency indices. Previous studies have used energy intensity, abatement cost intensity, and survey indices for regulations as proxies for the strictness of environmental policy. However, they have overlooked the indirect effect of environmental regulations on trade flows. If the strong version of the Porter hypothesis is confirmed, we need to consider the effect of environmental regulation on gross domestic product (GDP), because GDP induced by environmental regulation affects trade flows. The present study clarifies the effects of regulation on trade flows by distinguishing between the indirect and direct effects. Our results indicate an observed non-negligible indirect effect of regulation, implying that the overall effect of appropriate regulation benefits trade flows.
Estimation of aerobic fitness among young men without exercise test
Authors: Tanskanen Minna M. , Kyröläinen Heikki , Santtila Matti , Tammelin Tuija
Published: September 2015

Study aim: to develop and estimate the validity of non-exercise methods to predict VO2max among young male conscripts entering military service in order to divide them into the different physical training groups.

Material and methods: fifty males (age 19.7 ± 0.3 years) reported their physical activity before military service by IPAQ and SIVAQ questionnaires. Furthermore, Jackson’s non-exercise method was used to estimate VO2max. Body mass and height were measured, body mass index calculated and VO2max measured directly in a maximal treadmill test. Subjects were randomly divided into two groups. The results of the Group 1 (N = 25) were used to develop a regression equation to estimate VO2max. The results of the Group 2 (N = 25) were used to evaluate the validity of the developed non-exercise methods and Jackson’s non-exercise methods to estimate VO2max by Bland and Altman plot. The validity was further evaluated by comparing the results to 12-minute running test performed by 877 male conscripts (age 19.6 ± 0.2 years).

Results: the developed models explained 68–74% of the variation in VO2max. Mean difference between directly measured and estimated VO2max was not significant, while Jackson’s method overestimated VO2max (p < 0.001). Both developed models were equally valid to divide conscripts into tertile group of fitness. However, 5% of the conscripts were classified into the highest fitness group based on both methods, but they were actually in the lowest fitness group based on a running test.

Conclusion: in practice, these findings suggest that developed methods can be used as a tool to divide conscripts into different fitness groups in the very beginning of their military service.
Review of the PE Metrics cognitive assessment tool for fifth grade students
Authors: Hodges Michael , Lee Chong , Lorenz Kent A. , Cipriani Daniel
Published: September 2015

Study aim: this study examined the item difficulty and item discrimination scores for the HRFK PE Metrics cognitive assessment tool for 5th-grade students.

Materials and methods: ten elementary physical education teachers volunteered to participate. Based on convenience, participating teachers selected two 5th grade physical education classes. Teachers then gave students (N = 633) a 28-question paper and pencil HRFK exam using PE Metrics Standards 3 and 4. Item difficulty and discrimination analysis and Rasch Modeling were used data to determine underperforming items.

Results: analysis suggests that at least three items are problematic. The Rasch Model confirmed this result and identified similar items with high outfit mean square values and low Point Biserial correlation values.

Conclusions: teachers are in need of valid and reliable HRFK assessment tools. Without the removal of three items in the PE Metrics HRFK exam for 5th-grade students, complete use of the exam could offer incorrect conclusions.
A Deluxe FETI-DP Preconditioner for a Composite Finite Element and DG Method

In this paper, we present and analyze a FETI-DP
solver with deluxe scaling for a Nitsche-type discretization
[Comput. Methods Appl. Math. 3 (2003), 76–85],
[SIAM J. Numer. Anal. 49 (2011), 1761–1787] based on a
discontinuous Galerkin (DG) method for elliptic two-dimensional problems
with discontinuous coefficients and non-matching meshes only across
subdomains. We establish a condition number estimate for
the preconditioned linear system which is scalable with respect to the number of subdomains, is quasi-optimal polylogarithmic with respect to subdomain
mesh size, and is independent of coefficient discontinuities
and ratio of mesh sizes across subdomain
interfaces. Numerical experiments support the theory and show that the deluxe
scaling improves significantly the performance over classical scaling.
Poeta fui. Dante und Vergil
Authors: Full Bettina , Westerwelle Karin
Published: September 2015

Riassunto

È Virgilio ad aprire la serie di incontri con autori, soprattutto latini ed italiani, che ha luogo nella Commedia - Virgilio, che come »poeta« e »maestro« salva Dante, personaggio ed autore, dal suo smarrimento nella selva. Contro lo svanire della fama terrena si afferma, nell’agire e nel parlare dei due protagonisti, una genealogia letteraria che diviene tangibile tanto nella figura dell’antico poeta - lo evidenziano anche le miniature dei manoscritti - quanto nel valore intrinseco di un linguaggio figurativo che si trova in concorrenza con l’allegoria teologica. Sulle tracce del sottile rimando al (peccaminoso) piacere visivo che può derivare dal pelo maculato della lonza, della trasformazione stilnovistica di Virgilio, ma anche del confronto tra arte divina ed arte umana questo saggio ripercorre la riflessione di Dante su metafora e immagine come si manifesta nel rapporto con Virgilio.
Novel 2D CRLH TL and Its ZOR and FOR Applied on Dual-Band Omnidirectional Radiation Antenna
Authors: Li Tian-Peng , Wang Guang-Ming , Duan Feifei , Zhou Cheng , Tan Rui-Lian
Published: September 2015

A new type of two-dimensional (2D) composite right/left-handed transmission lines (CRLH TL) which is composed of four one-dimensional (1D) CRLH TL is proposed in this letter. Each 1D CRLH TL consists of three metallic vias added for shunt inductance and an etched patch slot for series capacitance. Based on this structure, an antenna operating on zeroth-order resonance (ZOR) and first-order resonance (FOR) is designed and fabricated. By taking advantage of coaxially center feed and symmetric structure, a well omnidirectional radiation in XoY plane both in ZOR and FOR and a homogeneously suppressed cross-polarization is obtained. Also, the antenna has a gain value of 2.06 dB in ZOR
Neurogenic speech sequelae following suicide attempt by hanging: a case report
Authors: Wazeer Manal Muhammed , John Sunila , Rajashekhar Bellur
Published: September 2015

Background:

Attempting suicide by hanging has become one of the most preferred means among adolescents. Individuals who survive a suicide attempt by hanging have a range of deficits, including neuropsychological, neuropsychiatric, pulmonary and even speech and language deficits. Literature regarding speech and language deficits in cases of near hanging is especially limited.

Objective:

This study aimed to demonstrate the sequelae of neurogenic speech deficits following a suicide attempt by hanging, the treatment strategies, and prognostic issues in one such case.

Methods:

We report of Patient X who attempted suicide by hanging. The patient was admitted and a detailed speech and language evaluation was completed.

Results:

Patient X was diagnosed with hypoxic-ischemic encephalopathy with organic amnesic syndrome. Consequent to the neurogenic insult, the patient demonstrated speech deficits that were characterized by moderate flaccid dysarthria and neurogenic stuttering. Patient X underwent a week of treatment, subsequent to which there was an improvement in certain speech subsystems. However, the neurogenic stuttering symptoms did not resolve completely even post therapy.

Conclusion:

Individuals who survive a suicide attempt by hanging have a range of deficits, including speech deficits that need to be addressed by a speech language pathologist. This case report is an eye opener for speech language pathologists regarding their role in such cases.
Super-mesenteric-vein-expia-thrombosis, the clinical sequelae can be quite atrocious
Authors: Lole Harris Benjamin Howell , Walsh Jason Leo , Nazir Sarfraz A.
Published: September 2015

Superior mesenteric vein (SMV) thrombosis is a rare, potentially life-threatening complication of intra-abdominal infection. Here we present a case of massive SMV thrombosis secondary to appendicitis in a 13-year-old boy. He presented with vague abdominal pain and associated symptoms, persistently elevated serum inflammatory markers and a pyrexia of unknown origin. Sonography proved inconclusive, and a definitive diagnosis was made by abdominal contrast-enhanced computed tomography. He was treated with antibiotics and anticoagulation before interval elective laparoscopic appendectomy. The non-specific nature of the presenting symptoms makes SMV thrombosis an important differential to consider when dealing with such patients.

Authors: Kumar Sandeep , Kumar Amit , Badiyani Bhumika , Kumar Arunoday , Basak Debashish , Ismail Mohammed B.
Published: September 2015

Background:

Dental caries affects quality of life and has a negative impact on daily performance.

Objective:

The study was conducted to assess the impact of oral health and its associated factors in schoolchildren in the age group 12–15 years in Indore, Madhya Pradesh.

Methods:

A cross-sectional survey was conducted in schoolchildren in the age group 12–15 years. Sociodemographic and oral health related behaviors of schoolchildren were collected using a self-administered questionnaire. Child oral impact on daily performance (OIDP) questionnaire was used to assess the oral impacts. Oral examination was performed to check the presence of caries using decayed, missing and filled teeth (DMFT) index.

Results:

A total of 690 schoolchildren participated in the survey. The mean age of the children was 13.58 years. The overall prevalence of dental caries was found to be 47.2%. The prevalence of one or more impact in the study population was 36.5%. The most prevalent impact was difficulty in eating and cleaning of teeth and the least prevalent impact were emotion and studying. Results of logistic regression analysis showed that the type of school that a child goes to, socioeconomic status, material used, dental visit, and dental caries were significantly associated with the Child-OIDP affected score.

Conclusion:

Oral health had a significant effect on the quality of life of schoolchildren. The prevalence of dental caries was found to be high. Effective policies need to be drafted for oral health promotion in this age group.
Postnatal testosterone may be an important mediator of the association between prematurity and male neurodevelopmental disorders: a hypothesis
Authors: Rice Timothy R.
Published: September 2015

Children born premature are at risk for neurodevelopmental disorders, including autism and schizophrenia. This piece advances the hypothesis that altered androgen exposure observed in premature infants is an important mediator of the neurodevelopmental risk in males associated with prematurity. Specifically, the alterations of normative physiologic postnatal activations of the hypothalamic-pituitary-gonadal axis that occur in preterm males are hypothesized to contribute to the risk of neuropsychiatric pathology of prematurity through altered androgen-mediated organizational effects on the developing brain. The physiology of testosterone and male central nervous system development in full-term births is reviewed and compared to the developmental processes of prematurity. The effects of the altered testosterone physiology observed within prematurity outside of the central nervous system are reviewed as a segue into a discussion of the effects within the nervous system, with a special focus on autism spectrum disorders and attention deficit hyperactivity disorder. The explanatory power of this model is reviewed as a supplement to the preexisting models of prematurity and neurodevelopmental risk, including infection and other perinatal central nervous system insults. The emphasis is placed on altered androgen exposure as serving as just one among many mediators of neurodevelopmental risk that may be of interest for further research and evidence-based investigation. Implications for diagnosis, management and preventative treatments conclude the piece.

Published: September 2015

This study is designed to evaluate predictive value of first-trimester cystatin C levels for long-term pregnancy complications.

The cross-sectional study population consisted of patients who admitted to outpatient clinic of a Maternity Hospital between September 2013 and December 2014. Among the 203 participants who accepted to participate in the study, 174 subjects who continued antenatal follow-up in the same clinic were included in the final analyses. Cystatin C, blood urea nitrogen, Creatinine levels and estimated glomerular filtration rates were evaluated in the first-trimester routine antenatal visit. Mode of delivery and gestational complications were noted.

First-trimester cystatin C levels were significantly higher in cases complicated with preterm delivery and premature rupture of membrane (PROM) compared to uncomplicated ones (0.58±0.07 vs. 0.55±0.07, P=0.041, and 0.58±0.07 vs. 0.55±0.07, P=0.036). With a cutoff value of 0.505 mg/L, sensitivity of cystatin C for preterm delivery and PROM was 91.9% and specificity was 27.7% with a negative predictive value of 92.3% and a positive predictive value of 26.6%.

Detection of cystatin C levels in the first trimester of pregnancy for the prediction of preterm/PROM seems as a promising preliminary data. The relatively higher first-trimester cystatin C levels in complicated pregnancies are conspicuous. The results imply that in pregnancy cystatin C might be more than a marker for renal function.
Access and Investment in the ICT Sector for Developing Countries
Authors: Kathuria Vikas
Published: September 2015

The Information and Communication Technology (ICT) sector is characterized by rapid changes in technology. The innovation in the ICT has shown its benefits in not only facilitating better communications, but also in fostering development. Therefore, ensuring proper incentives to the private sector for innovation or diffusion of technology is crucial. However, incentivizing the private players may be challenging in developing countries, where majority of the population requires cheap access. Thus, this paper analyses the extent to which developing countries can ensure incentivizing the providers of technology, without failing on their commitment to provide cheap access to the poor. The paper analyses Local Loop Unbundling (LLU) and Universal Service Obligation (USO) and suggests ways to ensure adequate investment without jeopardizing access. The framework chosen in this paper is to see the changing treatment of LLU and USO in mature jurisdictions, and then analyze the viability of these policies in the socio-economic settings of developing countries. The framework also takes note of changes in the ICT technology.

The photoconductive, photorefractive and nonlinear optical properties of composites from polyvinylcarbazole or aromatic polyimide containing supramolecular ensembles of (tetra-15-crown-5) - phthalocyaninato gallium, indium, - phthalocyaninateacetato yttrium, - phthalocyaninato ruthenium with axially coordinated pyrazine molecules were investigated at 633, 1030 and 1064nmusing continuous and pulsed lasers. Supramolecular ensembles (SE) were prepared through dissolution of molecular metallophthalocyanines in tetrachloroethane (TCE) and subsequent treatment via three cycles of heating to 90∘C and slow cooling to room temperature. The zscan method in femtosecond and nanosecond regimeswas used for measuring nonlinear optical properties phthalocyaninato indium and yttrium in TCE solutions and polymer films. It was established that effect of heavy metallic atom is basic factor which determines the quantum yield, photorefractive amplification of laser object beam, dielectric susceptibility of third order and nonlinear optical properties of metallophthalocyanines.
Research in the Field of Organic Photovoltaics at the Institute for Problems of Chemical Physics of Russian Academy of Sciences
Authors: Troshin Pavel A.
Published: September 2015

In the present review we highlight the main research activities in the field of organic photonics and photovoltaics at the Institute for Problems of Chemical Physics of Russian Academy of Sciences (IPCP RAS). Extensive investigation of optical and electrical properties of π-conjugated organic compounds performed at IPCP RAS since 1960’s resulted in design of many exciting materials representing organic semiconductors, metals and superconductors. Organic Schottky barrier and p/n junction photovoltaic devices constructed at IPCP RAS in 1960’s and 1970’s were among the first examples of reasonably efficient organic solar cells at that time. These early discoveries inspired younger generations of the researchers to continue the work of their mentors and explore the world of organic materials and photonic devices such as molecular photonic switches, organic light emitting diodes, solar cells, photodetectors, photoswitchable organic field-effect transistors and memory elements.
Other-initiated repair in Cha’palaa
Authors: Floyd Simeon
Published: September 2015

This article describes the interactional patterns and linguistic structures associated with otherinitiated repair, as observed in a corpus of video-recorded conversation in the Cha’palaa (a Barbacoan language spoken in north-western Ecuador). Special attention is given to the relation of repair formats to the morphosyntactic and intonational systems of the language. It examines the distinctive falling intonation observed with interjections and content question formats and the pattern of a held mid-high tone observed in polarity questions, as well as the function of Cha’palaa grammatical features such as the case marking system, the nominal classifiers and the verb classification system as formats for repair initiation. It considers a selection of examples from a video corpus to illustrate a broad range of sequence types of opened and restricted other-initiated repair, noting that Cha’palaa had the highest relative rate of open repair in the cross-linguistic sample. It also considers the extension of OIR to other practices such as news uptake and disagreement in the Cha’palaa corpus.
Optimization of the Verbal Inflectional Paradigm by the Cyclic Application of Morphophonological Processes: Evidence from Potential Forms in Japanese
Authors: Sano Shin-ichiro
Published: September 2015

In Japanese, a series of morphophonological changes that reorganizes the verbal inflectional paradigms is currently underway. The changes in potential forms involve two innovative processes: ar-Deletion and re-Insertion. This paper analyzes these morphophonological changes in the Japanese potential forms, and models the mechanism that governs the sequential changes, using the Corpus of Spontaneous Japanese. By positing a chronological order between the changes, I argue that the initial change in consonant-final verbs is motivated by semantic disambiguation, and the subsequent change in vowel-final verbs is triggered by analogical leveling for the optimization of the conjugation paradigm. This analogical leveling reorganizes the paradigm in order to counter the increased discrepancy between potential forms of consonant-final verbs and vowel-final verbs caused by the previous change. I propose that positing this two-step process is crucial to understanding the diachronic changes at issue.
United States Arms Transfer Decision-Making: Determinants of Sales versus Aid

Published: September 2015

This article examines the determinants of United States arms transfers by examining military aid separate from military sales. Separation of the two types of transfers is necessary due to the different benefits the United States receives from the transfers. Sales create direct economic benefits while aid is economically costly. The results show that some political, strategic, and economic factors have differing effects on the type of transfer and its size.

Graphene/poly(vinylidene fluoride) dielectric composites with polydopamine as interface layers
Authors: Li Hairong , Xu Chenglong , Chen Zongyi , Jiang Ming , Xiong Chuanxi
Published: September 2015

A poly(vinylidene fluoride) (PVDF) nanocomposite incorporated with polydopamine-coated reduced graphene oxide (rGO@PDOPA) nanosheets has been developed with high dielectric permittivity and low loss for electricity storage applications. Structural analysis indicates that PDOPA was successfully anchored onto rGOs through non-covalent linkage under mild conditions. The presence of PDOPA layer between rGO and PVDF can not only prevent the agglomeration and direct contact of original rGOs but also enhance the interaction between PVDF and rGO and microcapacitor formation. Compared to rGO/PVDF composites, higher dielectric permittivity and lower loss factor were achieved simultaneously in rGO@PDOPA/PVDF nanocomposites at low and moderate frequencies. The PDOPA interface layers are effective in modifying the dielectric characteristics of the composites to increase the dielectric permittivity without the introduction of loss mechanisms. This study demonstrates that PDOPA is an ideal interface layer for the development of new percolative dielectric composites with high dielectric permittivity and low loss.
Series of Nine Cases of Axial Displacement of Distal Tibial and/or Fibular Shafts from Aircraft Crashes with Proposal of Potential Mechanisms
Authors: Richey Stephen L. , Richeý Katrina
Published: September 2015

Previously, a pair of aircraft crash fatalities was reported by Byard and Tsokos involving extreme trauma to the lower legs with avulsion of the musculature and extrusion of the distal tibial shaft through the inferior aspect of the feet and shoes. This report was important to both the forensics and the injury prevention fields because it demonstrates a finding that may help to indicate not only the severity and nature/direction of an impact but also the position of the extremities at the time of collision with the terrain. Thus, here are reported an additional nine cases out of a larger series of 1182 aircraft fatalities (0.7%) with similar findings and discuss the biomechanical origins of such injuries.

The Rotationally-Resolved Absorption Spectrum of Formaldehyde from 6547 to 7051 cm−1

Published: September 2015

We report new experimental data on the rotationally resolved room
temperature absorption spectrum of CH2O in the near infrared
(NIR) region between 6804 and 7051 cm
–1
(1470–1418 nm). Data have been obtained by cavity
enhanced absorption spectroscopy and complement the spectrum in the
wavelength range 6547–6804 cm
–1, obtained using
virtually the same experimental set-up and already published in an
earlier publication (Staak et al., J. Mol. Spectrosc. 229
(2005) 115–121). Several vibrational combination bands occur in this
region and give rise to a congested spectrum and over 4500 lines
with cross-sections over 5 · 10
–23 cm2 were observed. Recent
experimental studies using NIR absorption spectroscopy for quantifying
CH2O in different chemical systems indicate that the
absorption cross-sections obtained by Staak et al. may have been
overestimated. The results of these experiments are reviewed here and
a recommendation for absolute absorption cross sections of
CH2O in the NIR range will be given. Absolute absorption
cross-sections stated here are corrected by the recommended factor.
Wind profile and shear stress at reed-open water interface – recent research achievements in Lake Fertő
Authors: Kiss Melinda , Józsa János
Published: September 2015

The effect of emergent aquatic canopy on over-lake wind field was investigated through detailed field measurements. The aerodynamic roughness length above reed canopy and above open water was determined from eddy-covariance data. It was found that the aerodynamic roughness length at short fetches could be more sufficiently estimated from wave age relations than from the logarithmical profile formula, indicating that near the canopy wind profile might deviate from the theoretical logarithmical form. The presented calculations lead to an improved understanding of the wind profile realignment and wind shear stress development at the interface of the characteristic lake zones, also enhancing the accuracy of the modeling of various wind-induced processes.

Published: September 2015

Further to Directive 2009/28/EC on the promotion of the use of energy from renewable sources, the share of biofuels in transport should rise to a minimum of 10% in Member States by 2020. In Finland, the goal is set at 20%, and it is estimated that this can be produced entirely in domestic factories, as long as the projects already underway will be successful and additional industrial-scale biofuel plants would be built. The paper reviews the state of projects underway in Finland, and outlines current research activity in promoting waste and by-product — based biofuels.

Authors: Machalická Klára , Eliášová Martina , Netušil Michal
Published: September 2015

Thanks to intensive research in the field of polymer adhesives in the last few years, there is a possibility of using a glued joint with a real load bearing role. The reliability of adhesive in the connection during the lifetime of a structure is affected by many factors, but the initial choice of a proper adhesive material is the most crucial one. The article deals with the experimental analysis focused on the determination of material characteristics of adhesives in planar connections, it describes the effect of various factors on the behavior of an adhesive joint under increasing loads, its ultimate bearing capacity and its failure modes. The main investigated factors are the type of adhesive, the type of connected materials (material of substrate), surface treatment and the thickness of the adhesive layer. A special part of the article describes numerical models of a glued joint with respect to different types of adhesive.
The relationship between mining and segregated areas in Pécs
Authors: Dányi Tibor Zoltán
Published: September 2015

The mining industry located in the Mecsek Hills has played a decisive role in the life of Pécs, which developed into an industrial settlement in the 19th century. Although the extraction of raw materials was discontinued in the last Pécs mine in 2004, the mining industry as a mental and built heritage still remains. Smaller estates, characteristic colonies of the early years of mining, have been significantly re-evaluated. The parts of the city built near the previous workplaces, far from the center, serve as the residence of people with the lowest income. The majority of approximately 4 000 municipal rental-housing units belong to this type of environment. Therefore, the future of the former mining colonies is crucial for the local government.
Development of a land-use and transport interaction model as a part of a policy assessment framework for urban traffic calming
Authors: Juhász Mattias
Published: September 2015

Initiation of traffic calming measures is on the challenging agenda of most cities, which are in pursuit of creating livable urban areas. However, previous studies on this research pointed out that the knowledge of the strategic aspects of application of these restrictions is insufficient, which is blocking further progression. Therefore a comprehensive policy assessment framework has been proposed and developed, which is combining modern modeling tools with reliable, well-tried appraisal methods. This work is another milestone of this broader research and its aim is to elaborate the modeling part of the framework enabling and establishing further works. The objective of this paper is to give an overview on this process and the result of which is a land-use and transport interaction model. In addition, it is also intended to practically test the model on a hypothetical case and to demonstrate its suitability.
Piezo-resistive Pressure Sensor Array with Photo-thermally Reduced Graphene Oxide
Authors: Kazemzadeh Rouzbeh , Kim Woo Soo
Published: September 2015

We report a highly sensitive pressure sensor fabricated by photo-thermally reduced Graphene oxide (GO) with silver nano wires (AgNWs). Pressure sensors are fabricated in form of the inter-digitated capacitors (IDC) composed of two finger electrodes with pattern width of 500 µm. The fabricated IDCs are compared to the previously reported MEMS-based pressure sensors' sensitivity. The fabricated sensor is easily attachable on any surface for monitoring applied forces or pressure and maintains excellent electrical conductivity under high mechanical stress and thus holds promise for durable bio-medical sensors.

Published: September 2015

Tin oxide is of great interest due to their potential technological applications, such as: gas sensors, energy conversion, catalysts and others. Appropriate doping can further enhance the conductivity of the SnO2 material with little loss of transparency. Isolated tin iron oxide fibers (Sn1-xFexO2-δ) with x (molar %) = 0, 2, 4, 6, 8 and 10 were prepared by the electrospinning technique. Anhydrous SnCl4, FeCl3·6H2O, different alcohols, chloroform and a polymer (PEO) were used as precursor materials. Appropriate mixture of these reagents defines the deposition solution. The samples were deposited on glass substrates and annealed at 500o C. The fibers are characterized by scanning electron microscopy (SEM), impedance spectroscopy and temperature dependence current-voltage measurements. The fibers with diameters between 2 to 12 microns were used for sensorial purpose. Thus, water vapor sensor responses were also measured and the experimental results are tested using the Freundlich isotherms model.

Published: September 2015

Fibre Reinforced Polymer (FRP) is becoming a valid alternative to many traditional heavy metal industries because of its high specific stiffness over the more classical construction metals. Recent trend of more complex geometry of composites is causing increasing difficulty in composite manufacturing. A method to optimize the manufacturing process is thus imposed to ensure and improve the quality of manufactured parts. Because of the irregular 3D shapes of the composites, traditional flat sensor system is becoming unfavorable and nonpractical for monitoring purpose. In this work, the current development status of a deformable microsystem for in situ cure degree monitoring of a glass fibre reinforced plastic is presented. To accommodate the non-flat shape of the composites, the proposal is to interconnect non-deformable functional island, which contains the capacitive sensor for cure degree monitoring, with meander-shaped deformable interconnections. The developed sensor system is able to withstand the manufacturing process where change of pressure and internal strain, thus force exerted on the sensor system, is involved.
Retrospectiva Histórica do ensino agrícola no Brasil
Authors: Sobral Francisco José M.
Published: September 2015

Esse artigo tem por objetivo central tratar da questão da formação profissional agrícola. Desde o início do Século XX, o ensino agrícola
no Brasil se apresentou como meio de fixação do homem ao campo, isso ficou evidente nos ideários do “ruralismo pedagógico” ainda
na década de 1920. Mais tarde, inúmeras políticas educacionais voltadas para o meio rural tiveram esse mesmo objetivo. Com o surgi-
mento das agroindústrias no Brasil e posterior implantação de políticas voltadas à modernização do setor (Revolução Verde), inúmeras escolas agrotécnicas foram criadas com o objetivo de atender a essa demanda. O capital agroindustrial passou a requerer um profissional que, através da extensão rural, desse conta de levar a modernização aos seus agricultores, fazendo surgir o profissional Técnico em Agropecuária. No entanto, com a reestruturação do capital ocorrido à partir das décadas de 1980-90, são criadas políticas educacionais que redirecionam a lógica da formação profissional; formar para o mercado de trabalho é o objetivo central dessas políticas. Apontamos ainda os reflexos dessas políticas, principalmente para a agricultura familiar e os desdobramentos que se fizeram surgir após o Decreto 5.154/2004, que direciona a formação integral para a Rede Federal de Educação Tecnológica, objetivando uma formação emancipatória.

Культура в контексте междисциплинарных научных исследований в области образования (пер. с англ. С. Кучковской)
Authors: Cole Michael
Published: September 2015

Чтобы сформулировать условия, необходимые для осуществления общей реформы образования, автор исследует роль культуры в образовании в исторической перспективе. Организованное обучение является неотъемлемой характеристикой человека как вида, но школы возникают только тогда, когда множество людей начинают проживать поблизости друг от друга и пользоваться технологиями, позволяющими создавать избыточный продукт. Школьное образование связано с развитием институциональных иерархий и моделей культурного обмена, которые ассоциируются с письменностью и учетом, оно отражает усиление политико-экономического расслоения в обществе. Анализируя ряд стратегий, нацеленных на изменение основ школьного образования, автор раскрывает причины ограниченности их влияния. Происходящие в современном мире глобальные изменения могут, по его мнению, стать источником фундаментальной реорганизации образования. (Почётная лекция AERA 2010 г.)
