Authors: Kalaga Dinesh V. , Bhusare Vishal , Pant H.J. , Joshi Jyeshtharaj B. , Roy Shantanu
Published: September 2018

Industrial gas-liquid processes such as oxidation, hydrogenation, Fischer-Trospch synthesis, liquid-phase methanol synthesis, and nuclear fission are exothermic in nature; the reactor of choice for such processes is, therefore, a bubble column equipped with heat exchanging internals. In addition to maintaining the desired process temperature, the heat exchanging vertical tube internals are used to control flow structures and liquid back mixing. The present work reports the experimentally measured gas hold-up, mean liquid velocity and liquid phase turbulent kinetic energy, using the Radioactive Particle Tracking (RPT) technique, in a 120 mm diameter bubble column equipped with dense vertical tube internals covering 23 % of the total cross-sectional area of the column. The effect of superficial gas velocity (44–265 mm/s) on gas hold-up, mean liquid velocity and turbulent kinetic energy is presented and discussed. It has been inferred from the experimental results that the vertical tube internal located at the center of the column plays a vital role in affecting the hydrodynamics when compared to the conventional internal configurations reported in the literature. For the chosen dense internal configuration, the cross-sectional distribution of the gas holdup, mean liquid velocity and turbulent kinetic energy show asymmetry for all the superficial gas velocities investigated. The overall gas holdup and the liquid turbulence increases with an increase in the superficial gas velocity. The strong liquid circulation velocities have been seen upon the insertion of the dense internals.
Pilot-Scale Study on Improving SNCR Denitrification Efficiency by Using Gas Additives
Authors: Weiqing Zhou , Meng Liu , Baohua Huang , Xiaozhi Qiu
Published: September 2018

The experiment of improving Selective Non-Catalytic Reduction (SNCR) denitrification efficiency with gas additives (CH4 and C3H8) was carried out in the 50 kW circulating fluidized bed (CFB) pilot-scale equipment. The results show that the denitrification efficiency can reach 20 % when the reaction temperature is 650 °C, and the optimum mole ratio of C3H8/NH3 is 0.5. The denitrification efficiency can exceed 50 % when the mole ratio of C3H8/NH3 is 0.4 and the reaction temperature is 720 °C. However, the CH4 additive does not promote denitrification at this temperature. When the reaction temperature is 760 °C, the optimum denitrification efficiency of CH4 is 60 %, and the required CH4/NH3 is 0.8. Once the amount of CH4 exceeds the optimal value, the denitrification efficiency is suppressed. In addition, the concentrations of N2O and CO in the gas increase significantly with an increase of gas additives. Due to the incomplete oxidation of C3H8, a large amount of C2H4 is produced in the low-temperature region (< 750 °C) of SNCR.
Optical slot antennas and their applications to photonic devices

Published: September 2018

We present optical slot antennas and their applications to photonic devices. We show that metallic nanoslots have the properties of a slot antenna by measuring the transmission spectra and far-field radiation patterns and then prove that they can be physically regarded as magnetic dipoles in the optical region. Additionally, we can generate directional radiations from optical slot antennas by adopting the geometry of radiofrequency Yagi-Uda antenna and properly adding auxiliary elements called reflectors and directors to a single slot antenna. We present two cases as the applications of optical slot antennas. One is the integration of slot antennas to plasmonic waveguides. This combination can be used as a basic unit for optical interconnection to free space and plasmonic via in multilayered plasmonic structures. The other is the integration of slot antennas to the electrode of light-emitting diodes (LEDs). Using slot antennas, we can control the polarization and direction of emissions from LEDs. Besides the above-mentioned two cases, we expect that optical slot antennas have possible applications to various photonic devices and can be essential elements in future integrated photonic circuits with nanometer scales.

Germanium (Ge) has played a key role in silicon photonics as an enabling material for datacom applications. Indeed, the unique properties of Ge have been leveraged to develop high performance integrated photodectors, which are now mature devices. Ge is also very useful for the achievement of compact modulators and monolithically integrated laser sources on silicon. Interestingly, research efforts in these domains also put forward the current revolution of mid-IR photonics. Ge and Ge-based alloys also present strong advantages for mid-infrared photonic platform such as the extension of the transparency window for these materials, which can operate at wavelengths beyond 8 μm. Different platforms have been proposed to take benefit from the broad transparency of Ge up to 15 μm, and the main passive building blocks are now being developed. In this review, we will present the most relevant Ge-based platforms reported so far that have led to the demonstration of several passive and active building blocks for mid-IR photonics. Seminal works on mid-IR optical sensing using integrated platforms will also be reviewed.

Published: September 2018

A systematic search was carried out in the databases of Pubmed, Indmed and Mausam for articles on the effect of ambient temperature on health. Relevant data were extracted using a standard data abstraction form by two authors independently. The overall effects of ambient air temperature are reported as odds ratio (OR) and 95% confidence intervals (CIs) on mortality. Of 812 records identified, only seven were included in the final review as per pre-defined criteria. An increase in the all-cause mortality rate of 41% are reported during a heat wave in India. Risk ratios for all-cause mortality was in the range of 1.7–2.1. The dose-response relationship of ambient temperature and all-cause mortality and cardiovascular diseases are been reported. Current evidence on the effect of ambient temperature and health is sufficient to initiate an integrated response from policy makers, climate scientists and public health practitioners in India. Continued advocacy and generation of more robust evidence is needed.
From resistance to reconciliation and back again: A semiotic analysis of the Charlie Hebdo cover following the January 2015 events
Authors: Keren Ran
Published: September 2018

TheCharlie Hebdomagazine’s 1178 edition was published following the deadly attack against the magazine’s cartoonists on 7 January 2015. The cover portrays the prophet Muhammad holding a sign with the phraseJe Suis Charlie(“I am Charlie”), titled with the phrasetout est pardonne(“all is forgiven”). This paper utilizes two levels of semiotic analyses. The first applies a direct, first level, semiotic reading while the second applies Roland Barthes’ idea of “Myth.” The analyses identify the tension between resistance and reconciliation as a key dialectical axis that drives the interpretive process. Tensions between East-West, religious-secular, natives-immigrants, and Islam-Christianity are all invoked by this cover, generating an extraordinary example of the complexity that cartoons are able to carry out as a form of intertwining semiotic systems. The first level of analysis finds an appropriation of Muhammad’s image in order to deliver messages of reconciliation and solidarity. The second level of analysis – a reading of the cover through Barth’s “Myth” – finds instead a Christian martyr, a Jesus image, replacing Muhammad and functioning as a divisive force that feeds the discourse of cultural clash.
A cross-linguistic rarity in synchrony and diachrony
Authors: Grossman Eitan , Antonov Anton , Jacques Guillaume
Published: September 2018

This article shows that a hitherto unattested construction type – namely, adverbial subordinator prefixes – is in fact attested in several languages. While Dryer’s 659-language convenience sample does not turn up any clear example of such a construction, we argue that this is in part due to arbitrary coding choices that a priori exclude potential constructions of this type. In order to document the existence of adverbial subordinator prefixes, we present a number of languages with different genealogical and areal affiliations, each of which shows solid synchronic evidence for what appears to be a universally dispreferred feature. Furthermore, we identify some diachronic pathways through which adverbial subordinator prefixes grammaticalize.
The wziąć gram in Polish. A serial verb construction, or not?
Authors: Andrason Alexander
Published: September 2018

This article analyzes the categorial status of thewziąćgram – a construction that is composed of two consecutive inflected verbs: the minor verbwziąć‘lit. take’ (V1) and a major verb (V2) – within the radial network of serial verb constructions (SVC). After comparing thewziąćgram with properties associated with the prototype of a SVC and its cross-linguistic instantiations, the author concludes that the construction can be regarded as a relatively canonical member of the SVC category. The gram complies with all the primary characteristics of the prototype of a SVC, and exhibits various secondary properties and phenomena that are associated with or accompany SVCs across languages. The position of thewziąćgram is canonical even though the Polish language utilizes verbal serialization only minimally and belongs to a geographic area that is scarce for systems with productive serialization. In this manner, Polish proves that verbal serialization is a grammatical device that is not unknown to Indo-European languages of Europe.
Alienability splits in action nominal constructions
Authors: van Lier Eva , van Rijn Marlou
Published: September 2018

Adnominal alienability splits typically involve a coding asymmetry: inalienable possessive constructions are shorter (or zero-coded) and/or more bound than alienable possessive constructions. This has been explained using one of two functional principles: iconicity (possessive constructions reflect differential conceptual distance) or economy (possessive constructions are the result of differential usage frequency). Alienability splits may also affect the coding of arguments in action nominal constructions. For this phenomenon only the iconicity explanation has been invoked, using the semantic notion of control. In the present paper, we investigate the merits of the alternative economy explanation for the cross-linguistic distribution of (in)alienable possessive coding of arguments in such nominalizations. Based on typological and corpus data, we conclude that the economy explanation covers the widest variety of typological generalizations concerning split possessive coding, in both underived NPs and derived action nominals.
Caring Rehabilitation Climate, the Tripartite Efficacy Framework, and Adherence to Rehabilitation Programs Among Individuals With Parkinson's Disease: A Multiple Mediation Analysis
Authors: Greviskes Lindsey E. , Podlog Leslie , Burns Ryan D. , Jackson Ben , Dimmock James , Newton Maria , Dibble Leland E. , Pillow Wanda
Published: September 2018

Background and Purpose:

Adherence to physical therapy (PT) and secondary prevention programs (SPPs) is particularly low for individuals with Parkinson's disease. Preliminary research has linked perceptions of caring climates as well as enhanced tripartite efficacy perceptions to adherence during rehabilitation programs. In light of such preliminary research, the purpose of this study was threefold: (1) to examine relationships between perceptions of a caring climate and the 3 efficacy constructs within the tripartite model, (2) to examine the relationship between the tripartite efficacy constructs and adherence to PT/SPP exercises, and (3) to determine whether tripartite efficacy beliefs mediated the relationship between caring climate perceptions and adherence.

Method:

A total of 77 individuals with Parkinson's disease who were currently or recently enrolled in PT or an SPP were recruited and surveyed about their perceptions of the caring climate of their rehabilitation clinic, their tripartite efficacy perceptions, and their adherence to rehabilitation. Correlations and a multiple mediation analysis were conducted to address the purposes of this study.

Results and Discussion:

Results showed significant positive associations between all variables; however, all paths within the proposed mediation model were not significant. Specifically, the c paths linking the tripartite efficacy constructs with adherence were not significant. A follow-up analysis was undertaken to address potential suppression effects within the mediating variables, and this analysis revealed a statistically significant model with relation-inferred self-efficacy (RISE) as a sole mediator of the relationship between caring perceptions and adherence to rehabilitation.

Conclusions:

Several practical implications can be gleaned from the current study. First, practitioners should strive to enhance the caring climate of their clinic by employing techniques reported in previous literature, such as creating a supportive atmosphere, displaying benevolence, and paying attention. In addition, the results suggest that individuals' RISE perceptions, in particular, could be a viable target for enhancing adherence.
Life-Cycle Cost Analysis of Pay Adjustment for Initial Smoothness of Asphalt Pavement Overlay
Authors: Wang Hao , Wang Zilong , Zhao Jingnan , Qian Junyu
Published: September 2018

This study aims at developing pay adjustments for initial smoothness of asphalt pavement overlay using life-cycle cost analysis (LCCA). The relationship between the initial International Roughness Index (IRI) and pavement life based on the threshold of surface distress index (SDI) was developed to calculate the pay adjustment using LCCA. It was found that the terminal IRI values when pavement overlay life was reached based on the SDI threshold of poor condition had an average value of 128 in./mile (2.02 m/km) with standard deviation of 15 in./mile (0.24 m/km). The pay adjustments were significantly affected by the assumption of analysis period in LCCA considering single or successive overlay applications. The Bayesian approach with Markov Chain Monte Carlo (MCMC) methods was used to develop the probabilistic model between the expected pavement life and the initial IRI. The probabilistic distribution of pay adjustments was presented when the uncertainty was considered with respect to the effect of initial IRI on pavement life and the assumption of overlay sequence. Compared with the pay adjustment obtained from the deterministic approach, the probabilistic analysis resulted in a similar pay adjustment for the case of single overlay but a greater pay adjustment for the case of successive overlays. The proposed analysis approach can be implemented by agencies in decision making of quality assurance based on actual practice of maintenance strategy.

Međuovisnost SAD-a i EU-a na ekonomskoj, političkoj i sigurnosnoj razini povijesno je bila izvor suradnje, ali i tenzija između dvaju globalno važnih gospodarstava. Snažne ekonomske, političke i sigurnosne spone SAD-a i EU-a omogućile su tim gospodarstvima stjecanje globalne nadmoći jer se radilo o sponama među najmoćnijima prema ekonomskim i obrazovnim kriterijima. Sa svrhom zadržavanja globalne premoći, SAD i EU se nastoje uskladiti što se tiče suvremenoga bilateralnog trgovinskog sporazuma visokih standarda, takozvanog TTIP-a. Cilj Transatlantskog sporazuma o trgovinskom i investicijskom partnerstvu je postići dogovor o daljnjoj liberalizaciji i povećanju tržišnog pristupa putem eliminacije prepreka u trgovini dobrima, uslugama i poljoprivrednim proizvodima te investicijama kao i o procedurama vezanim uz javnu nabavu. Važni ciljevi sporazuma su i povećanje regulatorne usklađenosti i kooperacije na području: vanjskotrgovinske i sigurnosne politike, investicija i razvoja novih pravila vezanih uz izravne strane investicije, prava koja proizlaze iz intelektualnog vlasništva, radničkih prava i ekoloških standarda. U ovom članku istaknut će se najvažnije nesuglasice između SAD-a i EU-a vezane uz tzv. TTIP s primarnom svrhom definiranja potencijalnih rizika za održivi rast gospodarstva EU-a u budućnosti.

A New-Proposal Physical Examination Test for Unilateral Lower Extremity Edema
Authors: Ada Fatih , Emren Volkan
Published: September 2018

Objective: Patients with iliac vein compression syndrome (IVCS) usually present to the hospital with left-sided leg edema. We looked for an answer to the question: ‘’Can iliac vein compression syndrome (IVCS) be predicted with a reliable physical examination test in the differential diagnosis?’’

Methods: We tested a new physical examination on patients with only left-sided lower extremity edema. In this physical examination the widest area of the calf point (just below tuberosity of the tibia) and medial malleolus was measured in both legs on the Trendelenburg position at 30°and repeated in standing position. Then the iliac venography was performed.

Results: The test was performed on 32 (N = 32) patients with left extremity edema. IVCS was observed on 18 (n = 18) (56%) patients. The test was found to have 88% sensitivity and 92% specificity in IVCS.

Conclusion: This new physical examination finding, which may be valuable in diagnosing IVCS, is proposed for use in patients with unilateral left-sided edema to preclude unnecessary use of expensive diagnostic imaging methods.

Published: September 2018

Thousands of maize landraces are stored in seed banks worldwide. Doubled-haploid libraries (DHL) produced from landraces harness their rich genetic diversity for future breeding. We investigated the prospects of genomic prediction (GP) for line per se performance in DHL from six European landraces and 53 elite flint (EF) lines by comparing four scenarios: GP within a single library (sL); GP between pairs of libraries (LwL); and GP among combined libraries, either including (cLi) or excluding (cLe) lines from the training set (TS) that belong to the same DHL as the prediction set. For scenario sL, with N = 50 lines in the TS, the prediction accuracy (ρ) among seven agronomic traits varied from −0.53 to 0.57 for the DHL and reached up to 0.74 for the EF lines. For LwL, ρ was close to zero for all DHL and traits. Whereas scenario cLi showed improved ρ values compared to sL, ρ for cLe remained at the low level observed for LwL. Forecasting ρ with deterministic equations yielded inflated values compared to empirical estimates of ρ for the DHL, but conserved the ranking. In conclusion, GP is promising within DHL, but large TS sizes (N > 100) are needed to achieve decent prediction accuracy because LD between QTL and markers is the primary source of information that can be exploited by GP. Since production of DHL from landraces is expensive, we recommend GP only for very large DHL produced from a few highly preselected landraces.

Published: September 2018

Introducción. Se sabe que las actitudes que tienen los médicos hacia las personas gais y lesbianas podrían influir en el tipo de calidad de atención de salud brindada. Sin embargo, es poca la información que tenemos en el Perú respecto a las actitudes que tienen los médicos frente a la homosexualidad. Los objetivos del estudio fueron determinar las actitudes hacia la homosexualidad y su relación con algunas variables en un grupo de médicos del Hospital Nacional Guillermo Almenara Irigoyen, Lima, Perú. Estudio de enfoque cuantitativo, aplicado e inductivo, de diseño observacional y transversal. Participaron 142 médicos de 24 a 60 años, 38% mujeres y 62% varones. Métodos. Se utilizó la Escala de Actitud hacia la Homosexualidad (EAH-10) y la Escala de Actitud Religiosa (EAR), además se recolectaron variables sociodemográficas. Resultados. La puntuación media de la EAH-10 fue de 23,32. 46 (32,4%) de los médicos mostraron actitudes intolerantes hacia a la homosexualidad, siendo éstas mayores en varones (p=0,005) y aquellos que mencionaron estar afiliados a una religión (católicos y protestantes/evangélicos) (p=0,007). Se encontró en los varones una correlación lineal positiva entre la actitud religiosa y actitudes homofóbicas (r=0,343, p=0,001), y entre la edad y actitudes homofóbicas (r=0,204, p=0,015). El número de personas cercanas homosexuales conocidas mostró una relación negativa con las actitudes homofóbicas (r= 0,218, p=0,001). El análisis de regresión lineal multivariada mostró que el sexo masculino, el estado civil (divorciado/conviviente) y la EAR resultan asociadas con la EAH-10. Conclusiones. En la población de médicos analizada, se encontró en los varones una relación positiva significativa entre la actitud religiosa y actitudes homofóbicas, y entre la edad y actitudes homofóbicas. Además, se halló una relación negativa significativa entre el número de personas cercanas homosexuales conocidas y actitudes homofóbicas.

A Longitudinal Study of the Association of Clinical Indices of Cardiovascular Autonomic Function with Breast Cancer Treatment and Exercise Training
Authors: Kirkham Amy A. , Lloyd Matthew G. , Claydon Victoria E. , Gelmon Karen A. , McKenzie Donald C. , Campbell Kristin L.
Published: September 2018

Background

Cardiovascular autonomic dysfunction is an early marker for cardiovascular disease. Anthracycline chemotherapy and left-sided radiation for breast cancer are associated with negative autonomic function changes. This study's objectives were to characterize changes in, and the association of exercise training with, clinical indices of cardiovascular autonomic function across the trajectory of breast cancer therapy.

Subjects, Materials, and Methods

Seventy-three patients receiving adjuvant chemotherapy participated to varying degrees in supervised aerobic and resistance exercise during chemotherapy ± radiation and for 20 weeks after. Resting heart rate (HRrest) and blood pressure were measured weekly during chemotherapy. HRrest, exercise heart rate recovery (HRrecovery), and aerobic fitness were measured at enrollment, end of chemotherapy ± radiation, and 10 and 20 weeks after treatment.

Results

During chemotherapy, HRrest increased in a parabolic manner within a single treatment and with increasing treatment dose, whereas systolic and diastolic blood pressure decreased linearly across treatments. Tachycardia and hypotension were present in 32%–51% of participants. Factors associated with weekly changes during chemotherapy included receiving anthracyclines or trastuzumab, days since last treatment, hematocrit, and exercise attendance. Receipt of anthracyclines, trastuzumab, and left-sided radiation individually predicted impairments of HRrest and HRrecovery during chemotherapy ± radiation; however, aerobic fitness change and at least twice-weekly exercise attendance predicted improvement. By 10 weeks after treatment, HRrest and blood pressure were not different from prechemotherapy.

Conclusion

In this study, chemotherapy resulted in increased HRrest and tachycardia, as well as decreased blood pressure and hypotension. Anthracyclines, trastuzumab, and left-sided radiation were associated with HRrest elevations and impairments of HRrecovery, but exercise training at least twice a week appeared to mitigate these changes.

Implications for Practice

This study characterized changes in clinically accessible measures with well-established prognostic value for cardiovascular disease, and investigated associations with cardiotoxic treatments and the positive influence of exercise. The chemotherapy-related incremental increase in resting heart rate, with tachycardia occurring in one third of patients, and decrease in blood pressure, with hypotension occurring in one half of the patients, is relevant to oncology practitioners for clinical examination or patient report of related symptoms (i.e., dizziness). The weekly dose of two 60-minute sessions of moderate-intensity aerobic and resistance exercise that was identified as protective of cardiovascular autonomic impairments can easily be prescribed to patients by oncologists.
Cost-Effectiveness of Osimertinib in Treating Newly Diagnosed, Advanced EGFR-Mutation-Positive Non-Small Cell Lung Cancer
Authors: Wu Bin , Gu Xiaohua , Zhang Qiang , Xie Feng
Published: September 2018

Background

The objective of this study was to assess cost and effectiveness of osimertinib in treating newly diagnosed advanced non-small cell lung cancer with an epidermal growth factor receptor (EGFR) mutation from a public payer's perspective in the U.S. and China.

Materials and Methods

Markov models were developed to compare three treatment strategies: first-line use of osimertinib, first-line use of the standard first-generation EGFR-tyrosine kinase inhibitor (EGFR-TKI) followed by the second-line use of osimertinib, and the standard first-generation EGFR-TKI therapy (standard care [SOC]). Clinical data, cost, and utility data were mainly derived from published literatures. Deterministic and probabilistic sensitivity analyses were conducted to assess the robustness of the incremental cost per quality-adjusted life year (QALY) between the treatments.

Results

The resultant incremental cost per QALY gained for the first-line osimertinib versus SOC was $312,903 in the U.S. and $41,512 in China. The incremental cost per QALY for the second-line osimertinib versus SOC was $284,532 in the U.S. and $38,860 in China. The probability of the SOC strategy being cost-effective is 1.0 if the willingness to pay threshold is below $150,000/QALY in the U.S. and below $30,000/QALY in China.

Conclusion

Osimertinib as first-line treatment could gain more health benefits in comparison with standard EGFR-TKIs or second-line use of osimertinib. However, because of the high cost of treatment, the cost-effectiveness analyses were not in favor of the first-line use of osimertinib from a public payer's perspective in the U.S. and China.

Implications for Practice

Osimertinib as first-line treatment yielded the greatest health outcomes but is not a cost-effective strategy for lung cancer in the U.S. and China. The price of osimertinib has a substantial impact on economic outcomes.

Launching is a bridge erection method that provides significant advantages when there is difficult underdeck access for falsework, crane and heavy plant. In such cases, assembling the deck in a more accessible position and launching it over the piers may mean a significant saving of resources. In some cases access is simply not possible due to other constraints, for example over environmentally protected areas. This is the case of the north approach viaduct of the new Queensferry Crossing, a major cable-stayed bridge over the Firth of Forth in Scotland, UK. This paper provides a description of the approach viaduct north and its launch process. This viaduct is a single/twin-girder bridge with composite section and two spans of 101·5 m and 104 m. Owing to its particular characteristics and impressive launch weight of 6200 t, the launching process has not been conventional, and particular solutions have been used and combined to ensure full compliance with the strict design constraints. The assembly process was not conventional either, owing to space constraints and the weight and size of the pieces.

As one kind of metal–organic framework material, zinc l-phenylalanine chelate may combine the merits of organic and inorganic components at the molecular level, thus making it a preferred anode active material. However, reports about zinc l-phenylalanine chelate anodes for lithium (Li) ion batteries are still scarce at the moment. Herein, shape-controlled synthesis of zinc l-phenylalanine chelate was carried out through a facile liquid-phase precipitation reaction and subsequent lyophilization. The obtained zinc l-phenylalanine chelate was investigated by field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, galvanostatic charge/discharge and cyclic voltammetry. The results suggest that zinc l-phenylalanine chelate appeared as uniform nanofibers about 140 nm diameter and 2–5 μm long. Furthermore, the zinc l-phenylalanine chelate nanofiber anode exhibited satisfactory electrochemical performances. For example, the initial specific discharge capacity was as high as 255 mAh/g at 100 mA/g and the reversible capacity remained 109 mAh/g even at 1000 mA/g for 200 cycles. Additionally, the possible lithium-storage mechanism was also explored. The synergistic effect of the combination of organic/inorganic components at the molecular level, regular nanofiber-like morphology and structural cavities may facilitate good strain accommodation, short ionic/electronic transport paths and high electrochemical performance.

Oyun, çocuğun
fiziksel gelişiminin yanı sıra arkadaşlık ilişkileri kurarak sosyalleşmesini ve
duygusal gelişimini sağlayan önemli bir faktördür. Nüfusun ve dolayısıyla
yapılaşmanın günümüzdeki kadar yoğun olmadığı dönemlerde çocuklar zamanlarının
çoğunu evlerinin bahçesinde ve sokakta oyun oynayarak geçirirken günümüzde evin
içine hapsolmuş durumda giderek yalnızlaşmaktadırlar. Bu nedenle kentlerde
yaşayan çocukların fiziksel ve ruhsal olarak sağlıklı gelişebilmesi ve doğaya
özlemini giderebilmesi için kentsel açık-yeşil alan sistemleri içerisinde çocuk
oyun alanlarının önemi gün geçtikçe artmaktadır. Çocuk oyun alanları
planlanırken ve tasarlanırken çocukların güvenli bir ortamda gelişim
özellikleri, çocukların ve onlara eşlik eden ebeveynlerinin ihtiyaçları göz
önünde bulundurulmalıdır.

Bu bağlamda yapılan
bu araştırmada Nevşehir kenti çocuk oyun alanları peyzaj planlama ve peyzaj
tasarım ilkeleri doğrultusunda incelenmiştir. Çocuk oyun alanlarının kent yeşil
dokusu içerisinde nasıl konumlandırıldığı, hangi yaş grubuna hitap ettiği,
hangi tür oyun ünitelerine yer verildiği, donatı elemanları, donatılarda ve
zeminlerde kullanılan malzemeler ile bitkisel tasarımları yerinde gözlemlerle değerlendirilmiştir.
Belirlenen eksiklikleri gidermeye ve ileriye yönelik tasarım ve planlama
çalışmalarına katkı sağlamaya yönelik öneriler sunulmuştur.

The energy transition patterns of low-income households in South Africa: An evaluation of energy programme and policy
Authors: Israel-Akinbo Sylvia Olawumi , Snowball Jen , Fraser Gavin
Published: September 2018

The transition to modern energy carriers like electricity is an important way to achieve to eradicate energy poverty. This study investigated energy transition patterns and trends in low-income South African households. The marginal effects of the different determinants on the probability of choosing a specific energy carrier were computed and the influence of some endogenous characteristics in transitioning to modern energy carriers was explored. It was found that energy ladder behaviour exists for cooking while energy stacking was most likely for space heating and the pattern for lighting tended towards energy stacking. Dwelling type, household size and geographical location were among the key determinants of the energy transition pattern. Policies to reduce energy poverty need a multi-pronged approach and not only a focus on electricity access.
O QUE PODEMOS ESPERAR DA ESCOLA?: UMA REFLEXÃO PARA ALÉM DA MODERNIDADE
Authors: Amaral Fº Fausto dos Santos
Published: September 2018

O presente texto é uma reflexão sobre as esperanças que, no geral, depositamos no mundo escolar. Para tanto, procura compreender o fazer escolar para além dos parâmetros da Modernidade ainda presentes no mundo contemporâneo. Questiona se de fato a Escola é um agente de transformações sociais efetivas ou se o que ela pode é apenas e tão somente reproduzir o mundo existente, tal qual ele é, ou seja, regido pela monossemia da linguagem técnica e científica, que faz do mundo algo cada vez mais homogêneo, na medida em que, para subsistir, precisa reprimir sempre e a todo custo o outro de si.
Interpretation of Explanatory Variables Impacts in Compositional Regression Models
Authors: Morais Joanna , Thomas-Agnan Christine , Simioni Michel
Published: September 2018

We are interested in modeling the impact of media investments on automobile manufacturer's market shares. Regression models have been developed for the case where the dependent variable is a vector of shares. Some of them, from the marketing literature, are easy to interpret but quite simple (Model A). Alternative models, from the compositional data analysis literature, allow a large complexity but their interpretation is not straightforward (Model B).  This paper combines both approaches in order to obtain a performing market share model and develop relevant interpretations for practical use.We prove that Model A is a particular case of Model B, and that an intermediate specification is possible (Model AB). A model selection procedure is proposed. Several impact measures are presented and we show that elasticities are particularly useful: they can be computed from the transformed or from the original model, and they are linked to the simplicial derivatives.
Handling Compositional Time Series with Varying Number of Parts
Authors: Bergman Jakob
Published: September 2018

When different polling organisations conduct political party preference polls at different times, different parties might be reported. If the estimated voter shares of these polls are combined into a time series we obtain a compositional time series, but with varying number of parts, thus prohibiting the use of standard compositional time series analysis tools. We discuss the problem and suggest a solution by imputing the unreported parts. The method is applied to a short compositional time series of party preference polls from Sweden.
The Relation between Color Spaces and Compositional Data Analysis Demonstrated with Magnetic Resonance Image Processing Applications
Authors: Gulban Omer Faruk
Published: September 2018

This paper presents a novel application of compositional data analysis methods in the context of color image processing. A vector decomposition method is proposed to reveal compositional components of any vector with positive components followed by compositional data analysis to demonstrate the relation between color space concepts such as hue and saturation to their compositional counterparts. The proposed methods are applied to a magnetic resonance imaging dataset acquired from a living human brain and a digital color photograph to perform image fusion. Potential future applications in magnetic resonance imaging are mentioned and the benefits/disadvantages of the proposed methods are discussed in terms of color image processing.
Investigation of Antibacterial and Anti-biofilm Activity of Thymbra spicata Essential Oil on Multidrug- Resistant Pseudomonas aeruginosa Strains
Authors: TUTAR Uğur
Published: September 2018

Thymbra spicata has been used traditionally as herbal tea for
the treatment of some diseases such as asthma, bronchitis, respiratory, coughs,
and sore throat infection in Anatolia. In the current study, the essential oil
of T. spicata (EOTS) were
investigated for their antimicrobial, anti-biofilm activity and chemical
composition. The chemical composition of Thymbra
spicata was analyzed by gas chromatography-mass spectrometry (GC-MS).
Antimicrobial and anti-biofilm properties were determined using broth
microdilution methods. According to the results of the present study, the GC-MS
profile highlights that the mains compounds were found grandisol 21.99%,
cadinol 6.45%, lavandulol acetate 4.39%. The antibacterial activity of the EOTS
was evaluated by the micro-dilution method against multidrug resistant Pseudomonas aeruginosa. EOTS produced
inhibitory effects against the tested strains. It inhibited 11 clinical
isolates of against P. aeruginosa
with Minimum Inhibitory Concentration (MIC) values in the range of 1.56-12.5
μl/mL. Minimum Biofilm Inhibitory Concentration (MBIC) value was found to be
range of 3.12-25 (μl/mL) while the Minimum Biofilm Eradication Concentration
(MBEC) value was found to be 6.25-25 (μl/mL). MIC value of the EOTS was applied
onto the bacterial biofilm formations. It was seen that biofilm metabolism was
reduced by 2.0-51.6 %. The findings of this study show that EOTS has
antibacterial and anti-biofilm activity against P. aeruginosa isolates. Thus, essential oil of T. spicata may be useful a potential source for the treatment of
multidrug resistant P. aeruginosa
infections and biofilms.
