Gentrification and functional change in Budapest – ‘ruin bars’ and the commodification of housing in a post-socialist context
Authors: Olt Gergely , Csizmady Adrienne 
Published: May 2020

AbstractThe growth of the tourism and hospitality industry played an important role in the gentrification of the post-socialist city of Budapest. Although disinvestment was present, reinvestment was moderate for decades after 1989. Privatisation of individual tenancies and the consequent fragmented ownership structure of heritage buildings made refurbishment and reinvestment less profitable. Because of local contextual factors and global changes in consumption habits, the function of the dilapidated 19th century housing stock transformed in the 2000s, and the residential neighbourhood which was the subject of the research turned into the so called ‘party district’. The process was followed in our ongoing field research. The functional change made possible speculative investment in inner city housing and played a major role in the commodification of the disinvested housing stock.
Transferring Urban Mobility Studies in Tehran, Istanbul, and Cairo to Other Large MENA Cities: Steps toward Sustainable Transport
Authors: Masoumi Houshmand , Fruth Erik 
Published: May 2020

AbstractThe number of urban mobility studies and projects in the three large metropoles of the Middle East and North Africa (MENA) region, Tehran, Istanbul, and Cairo, is growing while other large cities do not enjoy a large share. It would be efficient for those other large cities to adapt the experiences, projects, and studies of Tehran, Istanbul, and Cairo to their own contexts. This paper can help facilitate that adaptation. It investigates the transferability and generalisability of the findings of a recent publication by the lead author on mobility choices in Tehran, Istanbul, and Cairo to some other large cities of more than one million inhabitants in the MENA region. The discussion provided here can provide decision-makers in the MENA region with guidance on how to utilise the findings from a recent study on Tehran/Istanbul/Cairo in their own contexts. T-tests were conducted to test the comparability of the three base cities with a sample 57 others with populations of over one million people. The results show that it would be possible to adapt the urban mobility studies of the three base megacities to 3 to 27 cities based on different criteria. Key suggestions identified by this study include providing local accessibility, neighbourhood facilities, and cycling facilities as well as removing social and legal constraints to cycling, advertising cycling, informing people about the harm arising from the overuse of cars, and increasing street connectivity by adding intersections. According to the findings, these evidence-based recommendations can enhance sustainable mobility for the inhabitants of up to 27 large cities.
Addressing Socio-technical Issues in Built Environment Research: A Philosophical Premise
Authors: Daniel Maren Mallo , Molwus Jurbe Joseph , Nkup Joseph Tanko , Wuyokwe Nenrot Gombwer 
Published: May 2020

AbstractResearchers within the built environment disciplines have increasingly drawn on a plurality of social methods in order to enrich their research. Three decades down the line the place of philosophy in the choice of appropriate research methods is yet to be appreciated by some built environment researchers. Consequently, a lack of adventure in interpretive research, wrong choice of methods and underrepresentation of the qualitative approach are reported, which suggests the existence of a knowledge gap. This study is aimed at illustrating the philosophical premise for employing social research methods to address socio-technical issues in built environment research. In achieving this, reference was made to a fire incident in a student dormitory in Nigeria as a problem upon which contrasting–subjectivist and objectivist–philosophical positions were examined. The consideration of these philosophical positions and the choices that resulted from both spectrums were seen to have their strengths and weaknesses. To offset the weaknesses in each approach while also leveraging on the strengths that each approach offers, the paper illustrated how a compromise–pragmatist–position can be reached to allow for the choice of, and mixing of multi-methods to solve research problems that could not be adequately solved using any single method.
The conjoin sequence diagram: a method of describing conjoin sets
Authors: Hiscock Peter 
Published: May 2020

Conjoin analysis involves physically fitting back together objects broken in antiquity.Â Objects which are refitted are said to be 'conjoined', and a number conjoined together are called a 'conjoin set'. Conjoin analyses of stone artefacts began over a century ago with the work of Spurrell (1980; 1984). Subsequently, this approach has been used for a number of purposes. Cahen and colleagues used the vertical separation of conjoined artefacts to measure the extent of post-depositional displacement at Old World sites (Cahen 1978; Cahen and Moyersons 1977; Cahen et al 1979; Van Noten et al 1980). A number of researchers have used conjoin data to discuss the horizontal movement of humans and their debris across living floors (eg. Leroi-Gourhan and Brezillon 1966, 1972; Frison 1968, 1974; Van Noten, et al 1980; Singer 1984). Discussions of artefact breakage have often been accompanied by drawings of refitted fragments (eg. Lenoir 1975; Mallouf 1982). By providing information about sequential blows applied to a core, conjoin analysis has also aided in the reconstruction of the knapping process (eg. Kobayashi 1970; Frison 1974; Van Noten 1975; Fasham and Ross 1978; Leach 1984). In Australia, conjoin analysis has been used to examine vertical displacement (eg. Stern 1980) and to assist reconstruction of prehistoric stoneworking technology (eg. Noetling 1908; Luebbers 1978; Witter 1977).
Platypus Rockshelter (KBA:70), S.E. Queensland: chronological changes in site use
Authors: Hall J. , Hiscock Peter 
Published: May 2020

Platypus Rockshelter is a multicomponent archaeological site set into a conglomerate cliff on the Brisbane River near Fernvale, S.E. Queensland.Â Excavation revealed seven stratigraphic units in the smaller of two weathered cavities and these date from some 300 BP to younger than 540 BP. An abundance of bone, freshwater mussel shell, charcoal and a lesser amount of other organic material (e.g. feathers, hair, plants) was found associated with numerous stone artefacts. This good organic preservation, when linked with an internally consistent C14 dating series, a model of site formation and an initial understanding of site disturbance processes, makes it feasible to investigate variability in prehistoric human use of Platypus Rockshelter. Details concerning the site's complex stratigraphy, dating and site formation are the focus of a separate paper in this issue of QAR (Hall et al 1988). In accordance with the aims of the Moreton Region Archaeological Project - Stage II (Hall and Hiscock 1988), this companion paper presents data on the assemblage content and discard patterns in order to discuss changing site use during the Holocene. In particular we raise the issue of how the changing morphology of the shelter may have influenced the temporal pattern of cultural discard and follow with a discussion of how the nature of assemblages may be employed to tease out some factors relating to temporal changes in site use. We also offer the caveat that changes in the discard rate of cultural material through time do not necessarily reflect shifts in "occupational intensity".
Production and characterization of Green Iron Oxide nanoparticles with antifungal properties against fungal pathogens
Authors: Momanyi Kerubo Rachael  , Rajiv P  
Published: May 2020

In this study, iron oxide nanoparticles were synthesized throughthe green chemistry method. It involved the use of plant extract for synthesis of metal oxide nanomaterials. Aqueous extract of Tridaxprocumbenswas employed for the production of iron oxide nanoparticles. T. procumbens is a weed and it has good medicinal properties.The green chemistry approach provides a simple, cost-effective and eco-innovative method to the synthesis of nanomaterials as compared to the other alternative methods. Phase, crystal, surface chemistry, size, shape and element composition of nanoparticles were assessed and determined by various techniques like Fourier transform infrared spectroscopy (FTIR),X-Ray diffraction (XRD),Scanning Electron Microscopy (SEM) and Energy dispersion X-Ray (EDX). In addition, the antifungal properties of the biosynthesized nanoparticles were investigated against plant fungal pathogens. Spherical-shaped nanoparticles with a size of 26 ± 5 nm were obtained using the extract of T. procumbens. Bio-molecules from T. procumbens served as reducing, cappingand stabilizing agents for the fabrication of nanoparticles. The highest zone of inhibition was obtained in S. rolfsii(16.5 ± 0.5)at 50 µg/ml of concentration of TFeONPs. Biosynthesized TFeONPs were capable of inhibiting the growth of fungal pathogens such as S. rolfsii and F. oxysporumand they might beemployed as antifungal agents in agriculture to control fungal infections.

Published: May 2020

Sabe-se que muitas escolas são ainda enraizadas no século XIX, trabalhando de forma tradicional, com carteiras enfileiradas e tendo como foco o professor, o conteúdo e o vestibular. Com o objetivo de confrontar esse modelo, este projeto foi realizado em uma escola particular bilíngue de Bauru, SP, nas aulas de Ciências de 8º e 9º anos do Ensino Fundamental no segundo e terceiro trimestre de 2018. Por estarmos no ano de comemoração dos 10 anos da escola, relacionamos esse fato ao estudo de alguns conceitos da Física, considerando, então, a construção, o desenvolvimento da escola e o dia a dia dela. Entendemos que esse projeto, “Os 10 anos da FourC e a Física”, possibilitou oportunidades de aplicação do conhecimento concomitantemente ao desenvolvimento de habilidades do século XXI, como trabalho em equipe e flexibilidade, sendo excelente estratégia do Ensino para a Compreensão. Isso foi possível ao colocar o foco nos alunos, tornando-os protagonistas de seu aprendizado.

Published: May 2020

TThe study was carried out during the yearr 2017 to determine the fresh and post-thaw quality of four Holstein Friesian bulls. Semen samples were examined for ejaculate volume, pH, mass activity, sperm concentration and sperm motility and sperm membrane integrity (HOST). The ejaculated semen volume of Holstein Friesian bulls was in the range of 6-8ml and differences in ejaculates were significant (P<0.01). The volume was significantly (P<0.05) higher (7.75ml) when collected on 5th July, slightly decrease in volume (7.25ml) when collected on 12th May and 26th July. Semen pH was higher (6.65) for 26th July ejaculation and lowest (6.55ml) for 24th May ejaculation. The results indicated that the semen of Holstein Friesian bulls did not have considerable variation in pH during May – July. Most of the semen samples were creamy white and yellow in colour, while few samples were milky white and watery. Mass activity score of semen samples indicated vigorous movement with moderate rapid waves and eddies. The sperm motility of fresh vs post-thaw semen was obtained 72.80 vs 48.75 percent (12th May), 75.00 vs 48.75 percent (24th May), 76.25 vs 55.00 percent (2nd June), 73.75 vs 52.50 percent (21st June), 75.00 vs 56.25 (5th July) and 75.00 vs 50.00 percent (26th July). In case of post-thaw semen, highest sperm motility of 56.25 percent was recorded in semen ejaculated on 5th July, while lowest post-thaw sperm motility of 48.75 percent was observed in semen ejaculated on 12th May and 24th May. Highest sperm concentration of 1549.75x106 was determined in semen ejaculated on 21.06.2017 and lowest concentration (1259.50x106) in 26.07.2017 collected samples. It was concluded that sperm motility was significantly (P<0.01) affected by semen types (fresh and post-thaw), while sperm concentration was also significantly (P<0.01) affected by ejaculation date and bulls. The membrane integrity (HOST) of the pooled data on fresh semen samples over a period of three months was 58.37 percent against post-thaw membrane integrity of 44.79 percent.

Abstract

A metabolic marker in the blood of individuals exposed to air pollution is plausible as some environmental pollutants have been observed to enter the blood stream directly from lungs. The main objective of the current review is to find out changes in biochemical parameters of human blood as a result of environmental pollution. Spatio temporal models involving measurement of Air Quality Index were accommodating to find out the results of development of an aggregate air quality index. Results depicted that mean values of RBC and hemoglobin concentration in blood of exposed children were significantly different from those of non-exposed group. Air pollution may adversely affect children's erythrocytes, particularly PM10 have a significant negative relationship with hemoglobin and RBC numbers while a positive significant relationship with WBC and platelet count. Higher concentrations of air pollutants exposed to pregnant women significantly higher the incidence of pregnancy anemia’s. A strong dose-response relationship was confirmed for both contaminants. It is difficult to establish a causal relationship between specific environmental exposures and complicated multifactorial health outcomes, the application of non-targeted metabolite profiling to assess the effect of air pollution on blood metabolite. Therefore in the present study the main emphasis has been made on the effects of various polluted environment contaminants, their biochemical effects on the composition of blood and various associated disease.

Polymerases were revealed first in 1970s. Most important to the modest perception the enzyme responsible for nuclear DNA replication that was pol , for DNA repair pol and for mitochondrial DNA replication pol DNA construction and renovation done by DNA polymerases, so directing both the constancy and discrepancy of genetic information. Replication of genome initiate with DNA template-dependent fusion of small primers of RNA. This preliminary phase in replication of DNA demarcated as de novo primer synthesis which is catalyzed by specified polymerases known as primases. Sixteen diverse DNA-synthesizing enzymes about human perspective are devoted to replication, reparation, mutilation lenience, and inconsistency of nuclear DNA. But in dissimilarity, merely one DNA polymerase has been called in mitochondria. It has been suggest that PrimPol is extremely acting the roles by re-priming DNA replication in mitochondria to permit an effective and appropriate way replication to be accomplished. Investigations from a numeral of test site have significantly amplified our appreciative of the role, recruitment and regulation of the enzyme during DNA replication. Though, we are simply just start to increase in value the versatile roles that play PrimPol in eukaryote.

Sumber tegangan arus searah memiliki peranan penting dalam pengoperasian peralatan elektronik yang berfungsi sebagai catu daya. Catu daya tersebut berupa sumber bolak-balik atau yang dikenal dengan AC (Alternating Current). Kemudian dalam hal ini sumber AC tersebut disearahkan dengan komponen rectifier. Komponen rectifier dibagi menjadi dua jenis di antaranya penyearah tidak terkontrol dan penyearah terkontrol, untuk mendapatkan tegangan output yang berubah-ubah dari penyearah tidak terkontrol dengan merubah tegangan sumber AC masukan menggunakan AC Voltage Regulator, sedangkan menggunakan penyearah terkontrol untuk mendapatkan tegangan DC yang dapat dirubah-rubah cukup dengan mengontrol sudut penyalaan α dalam keadaan tegangan masukan konstan. Dengan menggunakan motor DC magnet permanen yang mana flux magnet dalam keadaan konstan, untuk mengatur kecepatan dari motor DC magnet permanen yaitu dengan mengatur tegangan terminal, untuk mengatur tegangan terminal dari motor DC tersebut menggunakan rangkaian semikonverter dengan merubah sudut α untuk mendapatkan putaran yang diinginkan. Hasil yang diperoleh dari sudut α 105o dengan Vs konstan, Vdc bernilai 71,2367 Volt, Vrms 121,57 Volt dan memiliki arus sebesar 0,03 Amp, semakin besar sudut penyalaan semakin kecil arus output yang diperoleh. Ketika motor DC dibebani, arus naik menjadi 0,047 Amp, sehingga kecepatan motor menjadi 3436,13 rpm.

La cuestión agroalimentaria en las economías petroleras:
Authors: Morales Espinoza Agustín 
Published: May 2020

Venezuela es un país que ilustra a la perfección la problemática de las economías que disponen del “oro negro” y que suelen caer en la tentación de apostar para su desarrollo de forma exclusiva en los beneficios petroleros, descuidando la promoción de la producción agraria nacional al amparo de la aparente “seguridad” que les proporcionan sus abundantes divisas para adquirir alimentos en el mercado mundial. Independientemente de otras consideraciones, esa clase de políticas frena el desarrollo agrario y rural, compromete la propia seguridad alimentaria de los países que las adoptan y se manifiestan sumamente frágiles cuando a las épocas de “vacas gordas” suceden (erráticamente) etapas de bajadas considerables de los precios del petróleo. Por tratarse de una colaboración relativamente especializada, los lectores no familiarizados con la economía agraria quizás puedan pasar directamente del apartado 2 del artículo al 4.
