Absztrakt:

Bevezetés: A krónikus fájdalom prevalenciája nemzetközi adatok
alapján 25% a tizenévesek körében, és a rossz életminőség mellett gyakran társul
az egészségügy kiterjedt használatával és túlzott gyógyszerfogyasztással. Kevés
magyarországi adat áll rendelkezésre a gyógyszerszedés gyakoriságáról és a
krónikus fájdalommal való összefüggéseiről. Célkitűzés: A
krónikus fájdalom prevelanciájának és lehetséges szociodemográfiai
rizikófaktorainak, valamint a gyógyszerszedést befolyásoló tényezőknek a
vizsgálata magyar tizenévesek körében. Módszer: Keresztmetszeti
epidemiológiai, kérdőíves vizsgálatot végeztünk budapesti 4, 6 osztályos
gimnáziumokban és általános iskolákban 354 diák bevonásával. A demográfiai
mutatók mellett vizsgáltuk a krónikus fájdalom jellemzőit, az egészségügyi
rendszer használatát, valamint a gyógyszerszedési szokásokat.
Eredmények: A vizsgált személyek 31,1%-a (n = 110)
szenvedett krónikus fájdalomban. A leggyakoribb fájdalom a végtagi fájdalom
volt, amelyet gyakoriságban a fejfájás követett. A tizenévesek 4,6%-ának (n = 5)
folyamatos fájdalma volt. A fiúk (χ2 = 9,4; p = 0,002) és a fiatalabb
életkorú (Mann–Whitney U = 10906,5; p = 0,004) alanyok körében szignifikánsan
alacsonyabb volt a krónikus fájdalom gyakorisága. Krónikus fájdalom esetén az
alvászavar szignifikánsan gyakoribb volt (χ2 = 8,9; p = 0,03). A
fájdalom fennállási ideje, erőssége, gyakorisága és időtartama egyenes arányú
szignifikáns kapcsolatot mutatott az orvoshoz fordulás prevalenciájával. A
megkérdezettek 78%-a (n = 276) szedett gyógyszert a megelőző hat hónapban,
ugyanakkor a rendszeresen gyógyszert szedők aránya is 48,3% volt (n = 171). A
gyógyszerhasználat valószínűségét a magasabb életkor, a női nem, valamint a
krónikus fájdalom megléte növelte. A krónikus fájdalommal élők körében
szignifikánsan magasabb, fájdalom miatt történt gyógyszerfogyasztást igazoltunk
(n = 83,0, 75,5%). Következtetés: A nemzetközi eredményekhez
hasonlóan a krónikus fájdalom, a gyógyszerszedés és az orvoshoz fordulás
prevalenciája a magyarországi tizenévesek körében is számottevő, ami jelentős
egészségügyi problémát jelent felnőttkorig terjedő hatásokkal. Orv Hetil. 2020;

Published: March 2020

Absztrakt:

Bevezetés: Számos tanulmány vizsgálta az emlőrákkal
diagnosztizált nők kötődési stílusát, és az eddigi eredmények rámutatnak arra,
hogy a betegek életminőségének és a gyógyulás optimális feltételeinek
biztosítása érdekében fontos figyelembe venni a kötődési mintázat és a
kapcsolati jellemzők közötti összefüggéseket is. Célkitűzés és
módszer: A jelen tanulmányban emlőrákkal diagnosztizált nők
kötődési stílusát (n = 135) kívánjuk felmérni, és összehasonlítani emlőrákkal
nem diagnosztizált nők csoportjával (n = 137) a felnőttkori kötődés, szorongás
és elkerülés dimenziói mentén. Vizsgáljuk továbbá a felnőttkori kötődés
jellemzőinek összefüggéseit a szubjektív egészségi állapottal, valamint a
párkapcsolattal és a szexuális kapcsolattal való elégedettség között.
Eredmények: A diagnosztizált csoportra a kötődési mintázat
szempontjából magasabb elkerülés, továbbá rosszabb szubjektív egészségi állapot,
alacsonyabb kapcsolati és szexuális elégedettség volt jellemző. A magasabb
elkerülés és a magasabb szorongás is alacsonyabb kapcsolati elégedettséget
jelzett előre, míg a szexuális elégedettség az emlőrák diagnózisával mutatott
negatív, a szubjektív egészségi állapottal pedig pozitív összefüggést.
Következtetés: Eredményeink arra utalnak, hogy az
emlőrákkal diagnosztizált nők kötődési mintázata, emellett pedig szubjektív
egészségi állapota is szerepet játszhat párkapcsolati és szexuális
elégedettségükben. A páciensek testi, lelki és kapcsolati jellemzőinek
figyelemmel kísérése és támogatása hozzájárulhat a jobb életminőség eléréséhez.

Lunar Standstills or Lunistices, Reality or Myth?
Authors: González-García A. César , Belmonte Juan A.
Published: March 2020

There is an intense debate in cultural astronomy on the importance of lunar standstills in prehistory or antiquity, and even on whether this elusive and difficult-to-understand phenomenon actually was then recognised. In the present paper, we seek to address those who advocate no longer using the terms "lunar standstill" or the related "lunistice". We begin by clarifying what the concept actually involves, before highlighting some case studies where proposed orientations to lunar standstills have explanatory value and a strong likelihood, connected to the lunar nature of the deities worshipped at particular sites. Finally, we present some relevant ancient texts that indicate awareness of lunar extremes.
Lunar alignments at Ur
Authors: Romain William F.
Published: March 2020

In ancient Sumer the Moon god, Nanna, was the patron deity for the city of Ur. In this article data are presented showing how the city of Ur was astronomically aligned to the Moon. Assessments are made using satellite imagery in combination with early maps and aerial photographs. Also shown is how the geographic location of Ur relative to Nippur may be related to the Moon’s 18.6-year nodal cycle. It is also shown how lunar calendric data are likely embedded in an ancient legend that tells of the Moon god’s journey from Ur to Nippur. Together these and other lines of evidence demonstrate how one of the world’s oldest cities was shaped through its entanglement with the gods – and in particular, the Moon god Nanna.   Open Access Attribution-NonCommercial-NoDerivatives: CC BY-NC-ND
Stone Pillar of a Condor Marked the Equinox at the Site of Buena Vista, Peru at 2200 BC
Authors: Benfer Jr. R.A. , Laura Lucio
Published: March 2020

The thesis of this study is that a well-attested mythological trope concerning the Fox and the Condor is apparent in archaeological features at Buena Vista in Chillón Valley, a site in Peru dating to 2200 BC. The myth identifies the Fox as an observer of human ritual activities who reports them to the Condor, who in turn flies up to the animate mountain peaks (apus) to inform them of these activities. With that information, the apus mete out punishments or rewards based on whether the rituals were adequate. At Buena Vista, this is expressed by an equinoctial alignment between a temple with an incised fox and a stone pillar carved into the shape of a condor.
Neolithic World View Lost in Translation
Authors: Stroud Katya
Published: March 2020

This paper considers the history of interpretations of the Maltese Neolithic Temples, using the site known as the Tarxien Temples as a case study. It examines the persistence of terminology adopted by archaeologists to explain the Tarxien complex during the early and midtwentieth century, and discusses how broader social trends and perspectives on religion have determined academic and popular understandings of such sites and their cosmological aspects. The paper shows how outdated misconceptions about the Neolithic sites remain commonplace, despite the rise of more dynamic interpretations in recent years that consider the structures in more relational contexts.

On a subclass of the generalized Janowski type functions of complex order
Authors: ÖZKAN KILIÇ Öznur , EROĞLU Nuray
Published: March 2020

In this paper, we introduce the class $\mathcal {JR}^{\lambda}_{b}\left(\alpha,\beta, \delta, A,B\right)$ of generalized Janowski type functions of complex order defined by using the Ruscheweyh derivative operator in the open unit disc $ \mathbb D=\left \{z\in \mathbb C: \left \vert z\right \vert <1\right \}$. The bound for the n-th coefficient and subordination relation are obtained for the functions belonging to this class. Some consequences of our main theorems are same as the results obtained in the earlier studies.
Forensic study of skin postmortem changes as a supplementary test to determine postmortem interval (first 78 hours)
Authors: Calderón Garcidueñas Ana Laura , Melo Santiesteban Guadalupe , Denis Rodríguez Edmundo , Cerda Flores Ricardo Martin , Denis Rodríguez Patricia Beatriz
Published: March 2020

Introduction. Determining the postmortem interval is usually based on macroscopic-morphological criteria (cadaveric phenomena); some other objective methods are often difficult to access in daily practice; therefore we analyze the usefulness of the histopathological examination of the skin as a supplementary method for determining the postmortem interval. Materials and methods.  23 patients and 92 skin biopsies were analyzed. All samples were taken in a maximum time of 6 h postmortem. Biopsies were classified into 4 groups according to the postmortem interval, with 23 biopsies in each group: 1 (1 to 6 h.); 2 (25 to 30 h.); 3 (49 to 54 h.); 4 (73 to 78 h); 21 histological criteria were analyzed with Fisher test and principal component analysis. Results.  Skin biopsies of 23 corpses (mean age 51.6 years, 15 males and 8 females) were studied. 21 histological criteria were analyzed by Fisher test; statistical significance (p <0.001) with a reliability of 94.61% was achieved in 15 parameters. With the 15 selected parameters, a principal component analysis established that there were differences among the 4 analyzed groups. Conclusions. The skin histological changes may be used as a supplementary parameter in the forensic evaluation of the early postmortem interval.

Estimating soil organic carbon stocks under commercial forestry using topo-climate variables in KwaZulu-Natal, South Africa
Authors: Odebiri Omosalewa , Mutanga Onisimo , Odindi John , Peerbhay Kabir , Dovey Steven , Ismail Riyad
Published: March 2020

Commercial forests are expanding globally, with great potential to absorb carbon and mitigate climate change. However, whereas the role of natural forests in carbon sequestration has been widely investigated, there is a paucity in the literature on the role of commercial forests in carbon assimilation. Hence, understanding the role of commercial forests in carbon storage is essential for quantifying local, regional or global carbon balances, which is valuable for climate change mitigation. Soil carbon is known to be the largest pool within any forest landscape, and is controlled by a wide range of physical and climatic factors. However, the relationship between soil organic carbon (SOC) and topo-climatic variables controlling its distribution within commercial forests is still poorly understood. Due to the limitations encountered in traditional systems of SOC determination, particularly at large spatial extents, geospatial techniques have recently emerged as a viable alternative for mapping soil properties. Therefore, this study sought to map SOC stocks variability within the commercial forest landscape, using landscape topo-climatic variables. A total of 81 soil samples was analysed for SOC concentrations and 31 topographic and climatic variables were used as predictors to SOC variability. To reduce multicollinearity, these variables were reduced to 11 using stepwise backward elimination and the maximum entropy (Maxent) algorithm was used for regression analysis to determine the relationship between SOC and the selected topo-climatic variables. Good accuracies were obtained for both training (area under the curve = 0.906) and test (area under the curve = 0.885) data sets, and demonstrate the effectiveness of selected topo-climatic variables and the Maxent algorithm in predicting SOC stocks. This study provides a framework for monitoring the status of soil carbon in commercial forest compartments and provides a viable approach for local, national or regional carbon accounting – valuable for climate change mitigation.

Significance:

Rainfall and temperature, as well as topographic variables (such as slope, elevation and topographic wetness index) are effective in mapping SOC distribution.

The model developed is useful in predicting SOC occurrence and yielded an effective framework for continuous monitoring and assessment of SOC.

The method developed in this study is cost-effective and suggests the use of other readily available climatic and topographic information for the prediction of SOC under commercial forestry in South Africa and indeed globally.

Results from this study are important to achieve the national carbon accounting objective and are also valuable to forest managers, ecologists and relevant stakeholders in understanding the spatial distribution of SOC.
Observation and quantification of aerosol outflow from southern Africa using spaceborne lidar
Authors: McGill Matthew J. , Swap Robert J. , Yorks John E. , Selmer Patrick A. , Piketh Stuart J.
Published: March 2020

Biomass burning in Africa provides a prolific source of aerosols that are transported from the source region to distant areas, as far away as South America and Australia. Models have long predicted the primary outflow and transport routes. Over time, field studies have validated the basic production and dynamics that underlie these transport patterns. In more recent years, the advancement of spaceborne active remote-sensing techniques has allowed for more detailed verification of the models and, importantly, verification of the vertical distribution of the aerosols in the transport regions, particularly with respect to westerly transport over the Atlantic Ocean. The Cloud-Aerosol Transport System (CATS) lidar on the International Space Station has detection sensitivity that provides observations that support long-held theories of aerosol transport from the African subcontinent over the remote Indian Ocean and as far downstream as Australia.

Significance:

Biomass burning in Africa can have impacts as far away as Australia.

Flow of aerosols from Africa towards Australia has long been postulated by transport models, but has been poorly characterised due to a lack of measurements.

The CATS instrument on the International Space Station has detection sensitivity that captures aerosol transport from Africa over the Indian Ocean to Australia.

Pleistocene large reptile tracks and probable swim traces on South Africa’s Cape south coast
Authors: Helm Charles W. , Cawthra Hayley C. , Combrink Xander , Helm Carina J.Z. , Rust Renée , Stear Willo , Van den Heever Alex
Published: March 2020

The Cape south coast of South Africa contains a wealth of Pleistocene vertebrate trace fossil sites in aeolianites and cemented foreshore deposits. Published studies have described mammal and avian tracksites identified along this coastline. We report here on a number of Pleistocene palaeosurfaces within the Garden Route National Park that exhibit tracks of large reptiles, including probable swim traces. The tracks were probably made by more than one species, and may include a crocodylian. There are no extant reptiles in this coastal region capable of making such tracks and traces, which probably represent an indication of a previously more extensive range for the Nile crocodile and a monitor lizard. These findings demonstrate the potential for ichnology to complement the traditional body fossil record. Two Middle Stone Age stone artifacts were found embedded in one palaeosurface containing multiple reptile trackways. These discoveries have implications for the understanding of Pleistocene palaeoenvironment and palaeoclimate – in an area which is important in the study of modern human origins.

Significance:

Large reptile Pleistocene fossil tracksites have recently been discovered on the Cape south coast of South Africa where there are no previous such records, and no reptiles of this size are currently found in the region.

These sites include the first reported probable reptile swim traces in Africa and one tracksite also contained two Middle Stone Age artifacts.

These discoveries have implications for Pleistocene environments and climate on the Cape south coast.
Gender pay transparency mechanisms: Future directions for South Africa
Authors: Bosch Anita , Barit Shimon
Published: March 2020

The gender pay gap – that is, the difference in wages between men and women for the same or substantially the same work, or work of equal value – still features prominently as a stumbling block in achieving South African gender equality. If South Africa is to dislodge its stagnant gender pay gap, especially for women in the middle and upper levels of the wage distribution, pay transparency – making gender differences in wages known to employees, government and the public – can compel employers to remunerate fairly and equally. We undertook a comparison between the global and national mechanisms of gender pay transparency to propose a way forward to increase transparency in gender pay for South Africa. In addition to a discussion of existing mechanisms, a summary of the gender pay transparency mechanisms of 16 countries is provided as supplementary material to the article. We found that South Africa could strengthen legislated transparency mechanisms, especially with regard to pay reporting and pay audits, provided that sanctions are attached to non-delivery of these duties. Reigniting the debate on strengthening and improving South African legislation and interpretation of existing governance codes in relation to the implementation, monitoring and enforcement of gender pay transparency mechanisms could strengthen the existing collective bargaining framework and provide the impetus to demonstrate that South Africa sees gender equality as an achievable reality, not an improbable ideology.

Significance:

Despite the presence of constitutional rights and enabling legislation to prevent workplace gender discrimination, South Africa continues to see a stagnant median gender pay gap of between 23% and 35%.

This study provides a global analysis to reinvigorate the debate on how South Africa can strengthen transparency mechanisms to close the gender pay gap.

Legislators, activists, board members, trade unions, academics, and organisational leaders are provided with suggestions on transparency mechanisms to improve efforts towards economic gender equality for South Africa.
Avaliação de planos de saneamento básico em municípios do sudeste Brasileiro
Authors: Ventura Katia Sakihama , Albuquerque Leilane Renovato
Published: March 2020

O Plano Municipal de Saneamento Básico (PMSB) é obrigatório por lei e deve conter minimamente os itens do artigo 19 da Lei Federal 11.445/2007. A avaliação é essencial para obter planos factíveis e personalizados. O objetivo deste artigo foi avaliar PMSBs em quatro municípios do sudeste brasileiro. As principais falhas, identificadas em levantamento bibliográfico, foram a concepção de planos com descrição superficial de pontos estratégicos do serviço de saneamento, falta de clareza quanto à participação da sociedade e da administração pública e, a ausência de mecanismos para avaliação do planejamento. O uso de indicadores de qualidade apontou que os planos selecionados atenderam medianamente o conteúdo mínimo, comprometendo a qualidade do planejamento a longo prazo. O desenvolvimento institucional para a gestão e controle do serviço de saneamento foi o indicador menos detalhado nos planos.

Fatores Que Influenciam Na Ocorrência De Ultrapassagens Perigosas Para Ciclistas
Authors: Louro Thiago Vinícius , Fontenele Heliana Barbosa , Silva Júnior Carlos Alberto Prado da
Published: March 2020

Em muitas cidades, devido à falta de infraestrutura adequada, os ciclistas têm de compartilhar as vias com veículos motorizados, o que gera diversos conflitos e afasta possíveis novos usuários. O objetivo deste estudo foi analisar os locais em que um ciclista foi ultrapassado por um veículo que trafegava acima de 90km/h ou acima da velocidade média dos demais veículos da via e com distância lateral menor do que 1,5 metros. Foram realizadas 13 viagens de bicicleta em um circuito fechado. Os dados de velocidade foram coletados com um radar e um monitor da Garmin®. A distância lateral foi medida com um sensor ultrassônico instalado no rack traseiro. Cerca de 47% das 1160 ultrapassagens registradas foram realizadas com distância lateral abaixo de 1,5m. Os trechos que apresentaram maior risco em relação à velocidade de ultrapassagem estão localizados na pista marginal de uma rodovia estadual e em vias urbanas com semáforos antes e depois de um vale formado por curvas verticais côncavas. Vias com inclinação negativa maior do que 5% favorecem a ocorrência de ultrapassagens com menos de 1,5 metros de distância lateral. Os resultados indicam a necessidade de maior fiscalização e conscientização, além da implementação de infraestrutura cicloviária, principalmente em trechos com rampas.

Abstract Using functional magnetic resonance imaging, we monitored the brain activity of 12 blind subjects and 12 control subjects, studied blindfolded, matched for age, gender, and musical experience. They were involved in the detection of rhythmic sequences ("beat") versus irregular ("no beat") composed of sounds or vibrotactile stimulations. Differences in cerebral activity between the two groups, in both sensory modalities, were observed in the occipital brain areas as well as in the heteromodal cerebral regions, including the parietal and frontal brain areas, which were recruited only in the early blind group. These results highlighted that early blindness induced brain differences in the brain network dedicated to perception of rhythm, with a participation of visual occipital brain areas. We concluded that, in the early blind, the visually deprived cortex switches its input modality from vision to audition and vibrotactile sense to perform a temporal processing task, regardless of the input modality, supporting the concept of metamodal organization of the brain.
Tratado Prático Sobre Funções de Singularidade: Modelamento de Cargas em Vigas de Concreto Armado
Authors: Serpa Nilo
Published: March 2020

Present treatise deals with applications of singularity functions from a broad perspective in civil engineering, extending its use to hyperstatics, and deepening mathematical questions little explored before. The content is presented through examples discussed in detail, giving to the reader a clear and objective reading. Original mathematical formulations are developed, such as the Macaulay-Serpa series. The treatise is extended to the calculation of hyperstatic porticoes and to the modeling of triangular loads. In this context, the theory appears as an important instrument for the analysis of ruptures in reinforced concrete beams. For the accomplishment of this treatise, an exhaustive search of bibliographical references was made, showing that the existent literature on the subject, mostly of foreign origin, is quite limited.

Key words: Singularity functions, reinforced concrete, hyperstatics, discontinuous loading, elastic curve.

==================================================================================== 

O presente tratado versa sobre aplicações das funções de singularidade numa ampla perspectiva da engenharia civil, estendendo seu uso à hiperestática e aprofundando questões matemáticas pouco exploradas anteriormente. O conteúdo é apresentado através de exemplos discutidos em detalhes, proporcionando ao leitor uma leitura clara e objetiva. Formulações matemáticas originais são desenvolvidas, como a série Macaulay-Serpa. O tratado é estendido ao cálculo de pórticos hiperestáticos e à modelagem de cargas triangulares.

KAYSERİ'DE YAŞAYAN GÖÇMEN MÜZİSYENLER (SELANİK GÖÇMENLERİ)
Authors: Değirmencioğlu Levent
Published: March 2020

Kurtuluş
savaşı sonrasında 24 Temmuz 1923'te İsviçre'nin Lozan şehrinde imzalanan Lozan
Barış Antlaşması sürecinde, Yunanistan ile Türkiye ülkeler arası nüfus değişimi
yapılması konusunda anlaşmıştır. Bu anlaşma kapsamında, Yunanistan'da yaşayan
Müslüman Türkler Türkiye'ye, Türkiye'de yaşayan Ermeni ve Rumlar da
Yunanistan'a gönderilmiştir. Değişim sürecinde Türkiye'ye gelen Müslüman
Türkler, 'muhacir' ya da 'göçmen' olarak isimlendirilmiştir. Yunanistan'ın
farklı şehirlerinden Türkiye'ye gelen göçmenler, Türkiye'de Ermeni ve Rum'ların
gönderilmesiyle boşalan bölgelere yerleştirilmişlerdir. İşte bu bölgelerden
birisi de Kayseri olmuştur. Diğer bölgelerdeki göçmenler gibi Kayseri'ye
yerleşen göçmenler de, yaşama yönelik yeniden bir düzen kurma sürecinde, maddi
ve manevi açıdan çeşitli zorluklarla karşılaşmışlardır. Bazıları kendi kültür
ve yaşantılarını burada devam ettirmişler, bazıları ise bulundukları
coğrafyanın yaşantısına adapte olmuşlardır. Kendi kültür ve yaşantısını devam
ettirebilen göçmenler, kendi yaşam tarzlarını ve kültürlerinde olan bazı
uygulamaları, yerleştikleri yerlerdeki insanlarla paylaşmış, bu yolla şehrin
sosyal yaşantısını doğrudan etkilemiş, bazı noktalarda da değişmesine vesile
olmuşlardır. Yukarıda bahsedilen etkileşimlerden birisi de müzik alanında
yaşanmıştır. Yunanistan'ın Selanik şehrinden gelen ve Kayseri'ye yerleşen
göçmenler, kültürlerinde var olan ve bazılarının geldikleri yerlerde meslek olarak
yürüttükleri müzik icracılığını burada da devam ettirmişlerdir. Kayseri'de
yaşayan Selanik'li müzisyenler, nesilden nesle aktardıkları bu yaşam kültürü
ile yaklaşık 90 yıldan beri Kayseri'nin sanat alanındaki temsilcileri olmuş, sosyal
yaşantı içerisindeki müzik eğitimi, konser, düğün, bayram, asker uğurlama vb.
faaliyetlerde görev almışlardır. Bu araştırmada, Kayseri'de yaşayan Selanik'li
müzisyenlerin tespit edilerek, demografik açıdan ele alınması ve müzisyenlerin Kayseri'nin
sosyal yaşantısına katkılarının ortaya konması amaçlanmaktadır. Bu amaç doğrultusunda, araştırmanın ilk aşamasında Kayseri'de
yaşayan Selanik göçmeni müzisyenler tespit edilmiştir. Araştırmanın ikinci
aşamasında, tespit edilen müzisyenler ile görüşmeler yapılmış, sorulan
yapılandırılmış sorularla müzisyenlere ait demografik bilgilere ulaşılmıştır.
Araştırmanın üçüncü ve son aşamasında ulaşılan bilgiler ile Kayseri'nin
günümüzdeki sosyal yaşantısı ilişkilendirilerek, göçmen müzisyenlerin
Kayseri'nin sosyal yaşantısına katkıları değerlendirilmiştir.
Structure of condensed gas in the uniform medium
Authors: Kılıç Abidin
Published: March 2020

The Bose-Einstein condensate, which has very low particle density and a highly complex quantum structure, has been proven experimentally for rubidium, sodium, lithium, hydrogen, metastable helium, cesium and chromium atoms to date. Because of the differences between the properties of these atoms and their binary interactions, many impressive results have been found in experimental work on condensation. The structure of a vortex in the uniform environment and the influencing factors are examined in this study.
Preparation and Characterization of the Sol-Gel Silica Containing Ionic Liquids as a Potential Adsorbent for the Removal of Cr(VI) Ions from Aqueous Solutions
Authors: ARABACI Merve , GİZLİ Nilay
Published: March 2020

In
this study ionic liquid mediated sol-gel silica adsorbents were prepared and characterized
to investigate the sorption of Cr (VI) ions from aqueous solutions. For this
purpose silica based adsorbents containing ionic liquids (ILs) were synthesized
by following the sol-gel method in ionic liquid media. Thus the high extracting
ability of ILs were combined with the surface properties of silica substances.
Commercial (Aliquat 336® and EMIMTf2N) and synthesized
([A336][NO3]) ionic liquids were incorporated directly by sol-gel process.
Silica based adsorbents were being initiated with silica precursor (TEOS),
water, alcohol and ionic liquid hydrolysis in the presence of an acid catalyst
then completed with a condensation reaction. Chemical and morphological
characterization of prepared adsorbents have been investigated by FTIR, SEM and
BET analysis. The materials exhibited average pore diameter of 2 nm, pore
volume of 0.3 cm3/g and BET surface area of 300–600 m2/g.
The sorption behaviors of adsorbents have been investigated by using a series
of batch sorption studies. Cr(VI) sorption percentages of the adsorbents were
enhanced by containing ILs up to 99% with the adsorption capacity of 31.74
mg/g. It can be concluded that sorption of Cr(VI) ions from aqueous solution by
sol-gel silica based adsorbents containing Aliquat 336 takes place favorably
and these type of adsorbents are promising agents in the adsorption processes.

Published: March 2020

In this paper, we study main headlines of brain development which is a major problem in neurobiology in present. Our aim here is to find the analytical solution of the equation that belongs to the brain development system. For this solution, the exchange of cerebellum granule cells in EGL (External granule layer of the cerebellum) is discussed. For this reason, Lie symmetry analysis is used. Obtaining solutions of this system means determining the behavior of the granular cell numbers at different stages. Knowing the behavior of these cells provides important information about the progression and development of diseases. Examples of these diseases are abnormal cerebellum development, cerebellum cancer. In this study, time dependent probability function related to division of two granule cells is examined. Then, analytical solutions are obtained for three different states of this function. Some tables and density graphics of these solutions are given.

Authors: KULE Merve , KİRİŞ Mehmet Eyüp
Published: March 2020

In this study, we derived a new integral identity for differentiable functions. However, we get new inequalities which is well known as Hermite-Hadamard (H-H) type by using the integral identity, which unifies the class of new and known harmonically convex functions. Moreover, in this study, the properties of first and second kind harmonically s-convex and harmonically s-Godunova-Levin functions are studied and some special cases are also dealt. Some important inferences are made at this study for supporting the results that obtained for classes of harmonically convex functions in previous studies.

A defuzzification method on single-valued trapezoidal neutrosophic numbers and multiple attribute decision making
Authors: DELİ İrfan , KIRMIZI ÖZTÜRK Emel
Published: March 2020

In this paper, we give multiple attribute decision-making (MADM) method where both the attribute value and attribute weight of alternatives are single-valued trapezoidal neutrosophic numbers (SVTN-numbers). In spite of existing ranking methods, no one can rank SVTN-numbers with human intuition consistently in all cases. Therefore, we introduce a novel defuzzification method for ranking SVTN-numbers. To do this, some basic definitions and operations on the concepts of fuzzy set, fuzzy number, intuitionistic fuzzy set, intuitionistic fuzzy number, single-valued neutrosophic set, SVTN-number are presented. Then, concepts of I. score function and II. score function to reduce the SVTN-numbers to fuzzy numbers are defined. Finally, multiple criteria decision-making (MCDM) method for multiple criteria decision-making problems by using the concept of I. score function and II. score function of SVTN-numbers and defuzzification of fuzzy numbers are developed. Also, we have used a numerical example to verify the feasibility and the superiority of the proposed method compared to the existing methods.
Deformation and stress analysis of crankshafts for single cylinder and four cylinder ic engine using ansys
Authors: CİHAN Ömer
Published: March 2020

The crankshaft is one of the most important loaded components in the engine, as it is experiencing cyclic loads in the form of a bending and torsion. In the study, crankshaft of the single-cylinder engine and crankshaft of the four-cylinder engine were designed in the SOLID WORKS software. Then these designs were transferred to ANSYS software with finite element method. Both crankshafts were compared in terms of stress and deformation. Critical areas had been identified as a result of stress and deformation. Comparative analysis of both shafts was not found in the literature. As a result, the values of stress and deformation increased as the speed increases in both shafts. Stress and deformation increased as the pressure increases associated with the speed applied on the crankpin journal. The stress in the crankshaft of the single cylinder engine was critically occurring on main journal, and the stress in the crankshaft of the four-cylinder engine was critically occurring on the crankpin journal. This much of the stress in the single cylinder engine crankshaft reduces the working life of the shaft. The shaft material should be selected considering the working conditions in crankshaft, or the material should be improved by coating the main journal and crankpin journal.
Investigation on the relationship between salinity stress and epibrassinolide in spinach (Spinacia oleracea L. cv. Matador) seedlings
Authors: SEVEN Serhat , SAĞLAM Serap
Published: March 2020

Soil salinity is a very important abiotic stress condition that affects plant growth and crop yield. Photosynthetic activity, fresh weight, total protein amount decrease due to salinity condition. Brassinosteroids (BR) are a new group of hormones in the steroidal structure which is involved in the plant hormone group. BRs play an important role in various physiological processes. BR shave a curative effect on the plants exposed to environmental stress. In this study, the effect on seedling development was examined by spraying 24-epibrassinolide (eBL), the active form of brassinosteroids, on the seedlings exposed to salt stress. For this purpose, seedlings are divided into three groups such as Hoagland, Hoagland+NaCl, Hoagland+NaCl+eBL. As a result of preliminary experiments, 150 mM NaCl as the salt concentration reducing seedling growth and 10-9 M eBL which promotes growth by reducing this inhibition were determined as the appropriate concentration. This study; biochemical analysis of spinach seedlings exposed to salt stress and applied to eBL showed the curative effect of eBL on salt toxicity.
