Authors: KAHRAMAN Zeyneb , YÜRÜTEN ÖZDEMİR Keriman
Published: December 2023

İklimin ortalama durumunda ya da onun değişkenliğinde onlarca ya da daha uzun yıllar boyunca süren istatistiksel anlamlı değişimler olarak tanımlanan iklim değişikliği; sanayileşme, fosil yakıt tüketimi, arazi kullanımı değişiklikleri ve ormansızlaşma gibi çeşitli insan etkinlikleri sonucunda hız kazanmış olup, küresel çapta iklim dengesizliği yaşanmasına neden olmaktadır. Günümüzde, sera gazlarının atmosferdeki birikimi kendini net olarak göstermekle birlikte, iklim değişikliğinin sonucu olarak, dünyanın doğal dengesi alt üst olmakta; biyoçeşitlilik zarar görürken, bazı canlı türleri yok olma tehlikesiyle karşı karşıya kalmaktadır. Diğer taraftan, aşırı sıcaklıklar ve şiddetli hava olaylarının yanı sıra meydana gelen çevresel olumsuzluklar, insan sağlığını doğrudan veya dolaylı olarak tehdit etmektedir. Bu bağlamda, iklim değişikliğine bağlı sıcaklık artışı, çalışan sağlığı açısından da riski artırmaktadır. Belirgin sıcaklık artışı göz önünde bulundurulduğunda, özellikle açık havada çalışan kişiler artan sıcaklardan dolayı yüksek risk altındadır. İklim değişikliği dünya genelinde önemli bir sorun iken, aynı zamanda yeterince önemsenmeyen ve göz ardı edilen bir durumdur. Bu durum alternatif çözüm arayışlarını zorunlu hale getirmektedir. Bu doğrultuda çalışmamızda, tarım sektöründe yaşanan iş kazalarının istatiksel olarak analiz edilerek, iklim değişikliğine bağlı sıcaklık artışının, iş kazaları üzerindeki etkisi incelenecektir. Çalışmada, Sosyal Güvenlik Kurumu’nun (SGK) yayınlamış olduğu 2014-2020 yılları arasında meydana gelmiş iş kazası verileri ile Meteoroloji Genel Müdürlüğü’nün 2012-2020 yılları arasındaki sıcaklık verileri kullanılarak istatistiksel analizlerle değerlendirilmiş ve gelecek yıllardaki durum tahmin edilmeye çalışılmıştır.

Sunulan çalışmada, sodyum katkılı Bi-2212 süperiletken sisteminde stronsiyum sitelere nano boyutta kalay katkısının etkisi araştırılmıştır. Katı hal tepkime yöntemi kullanılarak üretilen süperiletken örnekler X-ışını kırınım analizi (XRD) ve özdirenç sıcaklık ölçümleri (ρ-T) ile karakterize edildi. Bunun yanında, özdirenç sıcaklık grafiğinden elde edilen veriler kullanılarak, nano boyutta kalay katkılama oranı ve süperiletkenlik geçiş sıcaklığı arasında teoriksel ilişki elde edildi. XRD ölçümü ile yapılan faz analizlerinde bazı safsızlık fazlarının oluşmasına rağmen tüm örneklerde temel faz yapısının Bi-2212 yüksek sıcaklık fazının olduğu tespit edildi. Özdirenç sıcaklık grafiğinden elde edilen bulgularda tüm örneklerin süperiletken davranış sergilediği gözlemlendi. Deneysel çalışma sonucunda, 0.05 oranında nano boyutta kalay katkısı içeren örnek diğer örnekler ile karşılaştırıldığında daha iyi süperiletkenlik özelliklere sahip olduğu belirlendi. Diğer taraftan, Matematiksel formülasyonların elde edilmesi işlemi Matlab ortamında eğri uydurma aracı kullanılarak gerçekleştirildi. Elde edilen matematiksel formülasyonlardan yararlanarak 0.682 oranında nano boyutta kalay katkısının optimum süperiletkenlik özelliklerini sağlayabileceği teoriksel olarak belirlendi.

Comparison of the Effect of Nano Cellulosic Additives on Rheological Parameters for 3D Printable Concretes
Authors: KAROĞLU Ayşe , TÜRK Furkan , KESKİN Ülkü Sultan
Published: December 2023

In 3D printable concretes, fresh requirements such as pumpability, workability, constructability are affected by the rheological properties of the mixture. High yield stress and high viscosity cause blockages in the transmission line, while low yield stress and low viscosity cause the mixture to not provide the required shape stability. Even if the mixture to be printed has suitable rheological parameters, it is very important in terms of workability that it can be preserved over time. Here, cellulose nanocrystals and cellulose nanofibers were used in cement paste mixtures in order to ensure sufficient workability time in 3D printable concrete mixtures, and also to ensure that the originally designed rheological properties can be maintained over time. The Bingham model, which was created as a result of the measurements made with the viscometer device, was used to evaluate the rheological parameters of the mixes containing cellulose nanocrystal and cellulose nanofiber additions in varied amounts. As a result of the study, it was determined that the yield stress of the reference sample increased by 290% 45 minutes after the preparation of the mixture, while this rate decreased to 135% in the use of cellulose nanocrystals and to 79% in the use of cellulose nanofibers. While it increased by 205% at the end, this rate decreased to 37% with cellulose nanofibers and to 68% with cellulose nanocrystals. When the different additives are compared, it was concluded that cellulose nanofiber may be more effective than cellulose nanocrystal in controlling the increase in viscosity and yield stress over time.

On a potential relationship between climate change and seismic activity of Earth, explained by a general model
Authors: Nutu Catalin Silviu
Published: December 2023

The scope of this paper is to investigate a potential relationship between the melting of icecap caused by the global warming and the seismic activity of Earth. The first step is the analysis of seismic activity data of the last decades, in order to establish if there is an ascending trend in the frequency or magnitude of the earthquakes, or to see whether this data exhibits certain features which could indicate a certain change in the pattern of the seismic activity of Earth. If there is an ascending trend in the seismic activity, the correlation with the amount of the melted icecap (expressed in both: square kilometers and tons) is to be further analyzed. If however, there is no such ascending trend but still, the data shows certain changes in its pattern, these changes will be analyzed and explained using the model proposed and presented in this paper. This general basic model describes and explains how reduction of pressure exerted by the melted icecap leads to a redistribution of gravity pressing forces on the earth’s crust and releases additional movement forces of the tectonic plates, thus causing an increased seismic activity.

Published: December 2023

This study evaluated the potential of sweet potato peels from different varieties as substitute dietary energy in the early laying performance of Japanese quails. A total of 240 heads of ready-to-lay quails were laid out in a Randomized Complete Block Design (RCBD) and were assigned to the following treatments; ACommercial feeds, B-Home-mixed ration with 10% NISC Sp-35, C- Home-mixed ration with 10% NISC Sp-36, and D- Home-mixed ration with 10% Sp Japonita. The data were analyzed using one-way ANOVA for RCBD, and differences were determined using Tukey's Honestly Significant Difference Test (HSD) at p<0.05. The commercial diet improved hen-day egg production, FCR per dozen eggs, FCR per kilogram egg mass, and eggshell thickness. On the other hand, there were no significant differences (p>0.05) observed in egg weight, egg shape index, dry shell weight, yolk-albumen ratio and yolk total antioxidant activity. The yolk color score of HMR diets was significantly higher (p>0.05) and the yolk cholesterol deposition was lesser than those in the commercial diet. The financial analysis showed that the gross return was highest in the commercial ration. However, HMR diets performed better in terms of net income, return over feed cost, egg-to-feed price ratio, benefit-cost ratio, and return over investment.

Authors: Gomes Alexandro , Oliveira Maria Francisca do Nascimento , Musci Marcelo
Published: December 2023

RESUMO
A energia solar é uma das fontes de energia renovável promissoras que tem o potencial de atender à demanda energética futura em todo o mundo. Este artigo analisa os diferentes parâmetros que intervêm na determinação do ângulo de inclinação ótimo para a coleta máxima de energia solar. Ele propõe uma nova equação para calcular o ângulo de inclinação ótimo com base nos valores da latitude e longitude da instalação dos painéis solares. Um programa de computador, InclinaSol, foi implementado levando em consideração efeitos indesejados, como pó, poeira e outros fatores atmosféricos, que podem afetar a eficácia de funcionamento dos painéis solares. Foram realizados estudos de casos para os bairros de Guaratiba, Deodoro e Copacabana, por serem situados em diferentes regiões da Cidade do Rio de Janeiro. A escolha dessas localidades deveu-se ao fato das suas coordenadas geográficas e o distanciamento territorial. A investigação é realizada levando-se em consideração os ângulos de instalação de 0°, 17°, 30° e 45°. A partir daí, foram estimadas as incidências solares na superfície dos painéis solares a partir dos calculados pelo aplicativo RadiaSol, criado pelo Laboratório de Energia Solar da Universidade Federal do Rio Grande do Sul. Os resultados obtidos pelo aplicativo desenvolvido mostraram que, para a cidade do Rio de Janeiro, instalar um painel solar com a mesma inclinação média do telhado das residências (17º) é viável do ponto de vista técnico para instalação dos painéis. Porém, quando se avalia os efeitos indesejados, a inclinação calculada pelo aplicativo (30º) é mais vantajosa e resulta em valores de irradiação solar com uma diferença de no máximo 3,9%, em relação à inclinação de 17º.

Published: December 2023

Sunscreen is a chemical compound that helps shield the skin from ultraviolet light. Sunburn is caused by UVB radiation, but UVA radiation may cause more skin damage. A sunscreen that blocks both wavebands is ideal. The aim of this study was to use medicinal herbs and specific fixed oils to create a topical herbal sunscreen composition. The goal of this project is to create and evaluate a cosmetic (herbal sunscreen) that shields skin from the sun. Natural ingredients with a range of uses, such as emollient, moisturiser, base, anti-acne, and anti-sweating, include hibiscus and aloevera .Rose water, almond oil, vitamin E capsules, hibiscus flowers, etc. Actinic keratosis, squamous cell carcinoma, and melanoma can all be avoided with regular sunscreen use. Chemicals, either organic or inorganic, may be present in sunscreen. Sunscreen cream is another term for sunscreen. The object either absorbs or reflects solar radiation. UV radiation and provides skin defence. The use of screening materials that have been successful in lowering the indication has increased as a result of the rising incidence of skin cancers and the effects of UV radiation-induced photo damage
Tracking and Detecting Depression Level using Facial Recognition and PEN&IQ Test
Authors: Ms. Dhanashree V. Udgirkar
Published: December 2023

These Human facial expressions convey a lot of information visually rather than articulately. Facial expression recognition plays a crucial role in the area of human-machine interaction. Automatic facial expression recognition system has many applications including, but not limited to, human behaviour understanding, detection of mental disorders, and synthetic human expressions. Recognition of facial expression by computer with high recognition rate is still a challenging task.
Two popular methods utilized mostly in the literature for the automatic FER systems are based on geometry and appearance. Facial Expression Recognition usually performed in four-stages consisting of pre-processing, face detection, feature extraction, and expression classification. The human face is an important part of an individual’s body and plays an important role in knowing the individual’s mood. The face is where a human expresses all his basic emotions. In the existing system, they examine the mental state manually by assessing them but have many disadvantages like we cannot predict any accurate solutions based on the assessment score because we might be not sure what kind of emotions the human user would be all time. To overcome this problem, a novel system is proposed to suggest an effective solution for predicting the mental state dynamically, we propose a hybrid architecture invoking facial based emotion sequence, PEN test and IQ test. By consistent monitoring of a human’s emotion and subjecting to PEN and IQ tests, the human’s mental state is routed. Combination of the above three techniques provides promising results for mental state and self-control

Published: December 2023

Solitary plasmacytoma is a type of plasma cell tumour that can either be present in the bone marrow as a Solitary Bone Plasmacytoma (SBP) or the soft tissue as an ExtraMedullary Plasmacytoma (EMP). In the case of both the distinction from other plasma cell dyscrasias such as multiple myeloma is based upon clinical, serological, histological and radiological studies. Solitary plasmacytoma is rare and accounts for 3-5% of all plasma cell malignancies [1]. They occur more in men than women (65% to 35%) with a median age of 55 years [2]. The axial skeleton is the most common site of SBP. However, if the plasmacytoma is an EMP approximately 85% of these lesions occur in the head and neck mucosa. We present a case of solitary extramedullary plasmacytoma confined to the cervix resulting in significant therapeutic and management implications owing to this unusual site of disease.

Fifteen water samples from Well and Boreholes were collected from different schools located in some communities along Air Port road, Abuja and were analyzed for heavy metals concentration, Physicochemical and biological properties using standard methods. The result of the heavy metal concentrations shows; Cd in mg/l (0.0883-0.1113), Fe in mg/l (0.0300-0.2298), Zn(0.0000-0.8888), Mn in mg/l (0.0497-0.4598), Cu in mg/l (0.000-1.6427) and Pb in mg/l (0.0000 -1.5453). The physicochemical properties showed; Colour-Colourless, Odour- objectionable, Temperature oC (21-31), Alkalinity in mg/ml(1.5-7.3), Acidity in mg/ml(0.8-2.2), Hardness in mg/ml ( 1.2-3.6), Appearance ( Some are clear and some are not clear), pH (5.91-7.56), TDS in mg/l (80-2080), Turbidity in NTU (0.2-3.1) Conductivity in mg/l(123-9385) NH3 in mg/l(0.014-0.077), SO42- in mg/l(25.87-186.2) and F– in mg/l (0-0.38). The microbiological results shows that TBC ranges between 30-TNTC, TCC ranges between Nil-30 and E coli is Nil in all the samples. Total Dissolved Solid was found to be above the SON limits. Concentration of Fe, Cd and Pb were also above SON limits. Total Coliform Counts and Total Bacteria counts were also above the recommended limits by SON. Considering the high level of some of the physicochemical and microbiological parameters and the high concentration of Pb and Cd, the water is presumed unfit for drinking, cooking and pharmaceutical uses.

Circumstantial evidence and explanatory models for synapses in large-scale spike recordings
Authors: Stevenson Ian H.
Published: December 2023

Whether, when, and how causal interactions between neurons can be meaningfully studied from observations of neural activity alone are vital questions in neural data analysis. Here we aim to better outline the concept of functional connectivity for the specific situation where systems neuroscientists aim to study synapses using spike train recordings. In some cases, cross-correlations between the spikes of two neurons are such that, although we may not be able to say that a relationship is causal without experimental manipulations, models based on synaptic connections provide precise explanations of the data. Additionally, there is often strong circumstantial evidence that pairs of neurons are monosynaptically connected. Here we illustrate how circumstantial evidence for or against synapses can be systematically assessed and show how models of synaptic effects can provide testable predictions for pair-wise spike statistics. We use case studies from large-scale multi-electrode spike recordings to illustrate key points and to demonstrate how modeling synaptic effects using large-scale spike recordings opens a wide range of data analytic questions.
La opresión del pueblo kurdo y su lucha por la educación: un futuro de cambios sociales
Authors: Fernández Peña Catalina , Sánchez Jiménez José
Published: December 2023

A lo largo de la historia han existido numerosos pueblos que han estado sometidos a los dictámenes del más fuerte. Uno de ellos es el pueblo kurdo, que ha sido anulado como tal por distintas civilizaciones. El abuso de poder que han ejercido sobre los kurdos se ha visto reflejado en la prohibición del uso de su lengua, sus costumbres, su cultura y el robo sistemático de todas sus riquezas y recursos naturales, que han sido saqueados por el más fuerte. Nos preguntamos cómo es posible diseñar un sistema educativo en un pueblo que vive en campos de refugiados, donde están la mayor parte del tiempo bajo el ruido de las bombas y la muerte. Es increíble impartir clases en escuelas con recursos materiales y humanos tan precarios, teniendo en cuenta que los Estados opresores les obligan a seguir la educación en la lengua del Estado en el que viven, se ven obligados y obligadas a continuar con una labor educativa en la clandestinidad, luchando para que su cultura, lengua y tradiciones no se pierdan. Iniciativas sociales como la que se realizó en Rojava, impulsadas por las mujeres kurdas en el norte de Siria, es una buena manera de acabar con su aislamiento y anulación como pueblo, sirviendo como modelo de convivencia multicultural y multilingüe, del cual podemos aprender y trasladar a nuestros sistemas educativos occidentales capitalistas.

Abstract. Using the reanalysis and multiple observations, the possible impact of the Madden–Julian Oscillation (MJO) on early summer (June–July) rainfall in eastern China and its modulation by the Quasi-Biennial Oscillation (QBO) are examined. The composite results show that the suppressed (enhanced) convection anomalies for MJO phases 8–1 (4–5) are more concentrated over the maritime continent and the western Pacific during easterly QBO (EQBO). As a consequence, more significant wet (dry) anomalies develop in South (eastern) China during MJO phases 8–1 (4–5) configured with easterly (westerly) QBO. The enhancement and expansion of the anomalous tropical convection band do not necessarily correspond to enhancement of the extratropical circulation response to MJO phases 8–1 (4–5) configured with westerly (easterly) QBO. The anomalous high (low) over the maritime continent and western Pacific associated with MJO phases 8–1 (4–5) is intensified (deepened) during easterly (westerly) QBO, leading to large southwesterly (northeasterly) anomalies in South China and the coasts, carrying abundant (sparse) moisture. Two anomalous meridional circulation cells are observed for MJO phases 8–1 in the East Asia sector, with downwelling anomalies around 5–20∘ N, upwelling anomalies around 20–30∘ N, and another downwelling branch northward of 30∘ N, which are enhanced during easterly QBO. The anomalous meridional circulation cells are reversed for MJO phases 4–5, which are stronger during westerly QBO with the anomalous downwelling and dry anomalies covering eastern China. The combined impact of MJO phases 8–1 and easterly QBO on the early summer rainfall is noticeable in 1996, 2016, and 2020. The enormous rainfall amount appeared along the Yangtze River in 1996, 2016, and 2020 due to the extended period of MJO phases 8–1 under the background of the easterly QBO.

Abstract. The carbon isotopic signature inherited from soil and epikarst processes may be modified by degassing and prior calcite precipitation (PCP) before its imprint on speleothem calcite. Despite laboratory demonstration of PCP effects on carbon isotopes and increasingly sophisticated models of the governing processes, to date, there has been limited effort to deconvolve the dual PCP and soil–epikarst components in measured speleothem isotopic time series. In this contribution, we explore the feasibility, advantages, and disadvantages of using trace element ratios and δ44Ca to remove the overprinting effect of PCP on measured δ13C to infer the temporal variations in the initial δ13C of drip water prior to degassing and PCP. In nine examined stalagmites, the most widely utilized PCP indicators Mg/Ca and δ44Ca covary as expected. However, Sr / Ca does not show consistent relationships with δ44Ca so PCP is not the dominant control on Sr / Ca. From δ44Ca and Mg/Ca, our calculation of PCP as fCa, the fraction of initial Ca remaining in solution at the time the stalagmite layer is deposited, yields multiple viable solutions depending on the assumed δ44Ca fractionation factor and inferred variation in DMg. Uncertainty in the effective fractionation of δ13C during degassing and precipitation contributes to uncertainty in the absolute value of estimated initial δ13C. Nonetheless, the trends in initial δ13C are less sensitive to these uncertainties. In coeval stalagmites from the same cave spanning the 94 to 82 ka interval, trends in calculated initial δ13C are more similar than those in measured δ13C and reveal a common positive-anomaly initial δ13C during a stadial cooling event. During deglaciations, calculated initial δ13C implies a trend of greater respiration rates and higher soil CO2, although the higher interglacial drip water saturation favors more extensive PCP. Initial δ13C can be estimated for active and fossil speleothems from a range of settings, wherever there is confidence that Mg/Ca and/or δ44Ca provides a quantitative indication of past changes in PCP. Further study of Mg partitioning in speleothems will improve the robustness of Mg/Ca as a PCP proxy.

Abstract. The quaternary climate is characterised by glacial-interglacial cycles, with the most recent transition from the last glacial maximum to the present interglacial (the last deglaciation) occurring between ~ 21 and 9 ka. While the deglacial warming at southern high latitudes is mostly in phase with atmospheric CO2 concentrations, some proxy records have suggested that the onset of the warming occurred before the CO2 increase. In addition, southern high latitudes exhibit a cooling event in the middle of the deglaciation (15–13 ka) known as the Antarctic Cold Reversal (ACR). In this study, we analyse transient simulations of the last deglaciation performed by six different climate models as part of the 4th phase of the Paleoclimate Modelling Intercomparison Project (PMIP4) to understand the processes driving southern high latitude surface temperature changes. While proxy records from West Antarctica and the Pacific sector of the Southern Ocean suggest the presence of an early warming before 18 ka, only half the models show a significant warming (~1 °C or ~10 % of the total deglacial warming). All models simulate a major warming during Heinrich stadial 1 (HS1, 18–15 ka), greater than the early warming, in response to the CO2 increase. Moreover, simulations in which the AMOC weakens show a more significant warming during HS1 as a result. During the ACR, simulations with an abrupt increase in the AMOC exhibit a cooling in southern high latitudes, while those with a reduction in the AMOC in response to rapid meltwater exhibit warming. We find that all climate models simulate a southern high latitude cooling in response to an AMOC increase with a response timescale of several hundred years, suggesting the model’s sensitivity of AMOC to meltwater, and the meltwater forcing in the North Atlantic and Southern Ocean affect southern high latitudes temperature changes. Thus, further work needs to be carried out to understand the deglacial AMOC evolution with the uncertainties in meltwater history. Finally, we do not find substantial changes in simulated Southern Hemisphere westerlies nor in the Southern Ocean meridional circulation during deglaciation, suggesting the need to better understand the processes leading to changes in southern high latitude atmospheric and oceanic circulation as well as the processes leading to the deglacial atmospheric CO2 increase.
