Effect of Celery (Apium graveolens L.) Extract Administration on Kidney Function of White Rats (Rattus norvegicus) Wistar Strains Exposed to Lead
Authors: Selviana Barus Shella , Napiah Nasution Ali , Wienaldi Wienaldi
Published: June 2024

Lead significantly affects health because of its sensitivity to the central nervous system and rapid absorption rate. The phytochemicals included in celery, such as flavonoids, may mitigate lead-induced kidney damage. This research aimed to determine how administering celery extract affected the expression of the Caspase-3 gene and the kidney TNF-α gene in Rattus Norvegicus Wistar white rats exposed to lead. The research method true experiment examined the effects of 80 mg/day celery extract on Caspase-3 gene expression and renal TNF-α gene expression in rats exposed to lead. Each of the three groups will include six rats; there will be eighteen male Wistar rats in the study. The study used SPSS 26.0 and the Saphiro Wills test to analyze data on TNF-α and Caspase 3 expression in rats exposed to lead acetate (Pb). The results showed a normal distribution for the negative control group (K-) and the positive control group (K+) and a normal distribution for the treatment group (P). However, the paired t-test showed significant differences in all treatment groups (p <0.05), indicating a normal distribution in the data. The study concludes the impact of celery extract on kidney function in lead-exposed Wistar rats, revealing various active compounds like flavonoids. Despite insignificant caspase 3 reduction, flavonoids showed potential in mitigating lead-induced kidney damage.

Authors: Jarquín-Ramírez Mauro Rafael , Díez-Gutiérrez Enrique Javier , Palomo-Cermeño Eva
Published: June 2024

Este trabajo analiza el papel de los think tanks actuales en las políticas educativas a partir del estudio de caso del proyecto educativo de Diálogo Interamericano, el más representativo a nivel educativo en América Latina, así como los vínculos que esta organización ha generado con otros sectores para poder impulsar en las políticas de los gobiernos su programa de reforma educativa y en qué dirección se orienta la misma. La metodología de investigación utilizada ha sido el Análisis Crítico del Discurso (ACD) analizando los textos y documentos producidos por este think tank de 1995 a 2020. Los hallazgos reflejan que el Diálogo impulsa en América Latina políticas educativas globales que apuntalan el modelo neoliberal de crecimiento de la economía capitalista, incrementan la presencia de actores privados en la política educativa mediante la denominada gobernanza híbrida y abren nuevos nichos de mercado a las empresas en el “negocio educativo”.

Abstract. The runoff of surface melt is the primary driver of mass loss over the Greenland Ice Sheet. An accurate representation of surface melt is crucial for understanding the surface mass balance and, ultimately, the ice sheet's total contribution to sea level rise. Regional climate models (RCMs) model ice-sheet-wide melt volume but exhibit large variability in estimates among models, requiring validation with observed melt. Here, we explore novel processing of data from the Advanced SCATterometer (ASCAT) instrument onboard the EUMETSAT Metop satellites, which provides estimates of the spatiotemporal variability of melt extent over the Greenland Ice Sheet. We apply these new maps to pinpoint differences in the melt products from three distinct RCMs, where one is forced at the boundary with two different reanalyses. Using automatic weather station (AWS) air temperature observations, we assess how well RCM-modeled melt volume aligns with in situ temperatures. With this assessment, we establish a threshold for the RCMs to identify how much meltwater is in the models before it is observed at the AWS and ultimately infer the melt extent in the RCMs. We show that applying thresholds, informed by in situ measurements, reduces the differences between ASCAT and RCMs and minimizes the discrepancies between different RCMs. Differences between modeled melt extent and melt extent observed by ASCAT are used to pinpoint (i) biases in the RCMs, which include variability in their albedo schemes, snowfall, turbulent heat fluxes, and temperature as well as differences in radiation schemes, and (ii) limitations of the melt detection by ASCAT, including misclassification in the ablation zone as well as a temporal melt onset bias. Overall we find the RCMs tend to have a later melt onset than ASCAT and an earlier end of melt season with a similar but slightly smaller melt area than identified in ASCAT. Biases, however, vary spatially between models and with compensating errors in different regions, suggesting that a dedicated RCM might represent the surface across the entire ice sheet more effectively than the ensemble mean.

Published: June 2024

Abstract. Three-axis magnetic flux gate sensors are widely used in Chinese geomagnetic observatories, but due to their directional errors, it is necessary to study error correction methods to improve measurement accuracy. Firstly, the mechanism of directional errors produced by three-axis magnetic flux gate sensors is analyzed, followed by the development of measurement tools for conducting directional error measurement experiments on the high-precision three-axis magnetic flux gate sensors of the Chinese FGM-01 series. Experimental results show that correcting the Z-axis and D-axis directional errors is essential. The observation data after error correction, whether in terms of the standard deviation of its all-day baseline values or the relative difference magnitude with the reference instrument, significantly decrease, demonstrating the clear correction effect and proving the effectiveness of this correction method.

Purpose: The aim of the study is to investigate cognitive impairment (CI) in patients with different clinical forms of Multiple Sclerosis (MS) and to propose a suitable cognitive evaluation based on available tools for diagnosis and monitoring purposes. Materials and Methods: The following tests were used: Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Brief Visuospatial Memory Test-Revised (BVMT-R), Expanded Disability Status Scale (EDSS) and Magnetic Resonance Tomography 1.5Т (МRТ) in 60 consecutive patients; 22 were with first demyelination episode and 38 with MS. The control group of 40 healthy persons matched for sex, age and years of education. The follow-up period is three years. Results: The average screening values of PASAT, SDMT, BVSMT-R are considerably lower (р<0.05) in MS patients compared to the controls and CIS patients. Point's number in the progressive forms in comparison with RRMS is reliably smaller. There was no significant difference in results between SPMS and PPMS patients at screening (р>0.05). In the 3rd year, there is a significant cognitive progression in all studied groups and for all tests (р<0.05). Conclusion: The use of a neuropsychological screening test is a valuable method for registering CI in patients with relapsing-remitting course, as well as in patients with a progressive course of the disease. We recommend the SDMT for screening annual follow-up because it is easy to apply, validate and reliably report the progression of CI. In patients with visual disturbances and with arm weakness, it is better to use PASAT, taking into account the level of education and depression.

تداول الأسهم من خلال أسواق الأسهم هو وسيلة شعبية للمستثمرين للحصول على مكاسب رأس المال والأرباح. ومع ذلك، فقد وجدت أيضا بورصة أقل شهرة في الأسواق التقليدية المعروفة باسم البورصة الاجتماعية. وكانت مبادرات البورصة الاجتماعية التقليدية ناجحة بين عدد قليل من الاقتصادات التقليدية مثل البرازيل وكندا وسنغافورة/موريشيوس والهند مؤخرا. تمكن البورصة الاجتماعية المؤسسات الاجتماعية التي لها أسباب اجتماعية وبيئية تجارية من سرد مشاريعها أو أدواتها للمستثمرين للاستثمار فيها. على عكس البورصات الهادفة للربح، فإن هدف البورصة الاجتماعية ليس مكسبا نقديا للمستثمرين ولكنه عائد من حيث مواجهة الاضطرابات الاجتماعية والحفاظ على البيئة. وبعبارة أخرى، فإن تأثير الاستثمار هو هدف المستثمرين. وبالتالي، يؤثر المستثمرون على العالم من خلال استثماراتهم في المؤسسات الاجتماعية في البورصة. يبحث هذا البحث في آفاق تطوير بورصة اجتماعية إسلامية رقمية ويقترح أن الاقتصادات الإسلامية يمكن أن تقود بورصة اجتماعية إسلامية لنشر الرؤية الشرعية للعمل الخيري والاستثمار والاستدامة. وعند شرح هذا الاقتراح، استعرض البحث البورصة الاجتماعية للبرازيل وكندا وسنغافورة / موريشيوس والهند وأجرى ثلاث مقابلات متعمقة مع علماء بارزين في هذا المجال. وفي الوقت الذي يمهد فيه البحث الطريق لتمكين المؤسسات الاجتماعية التي تهدف إلى أسباب اجتماعية وبيئية من الحصول على التمويل والتعرض المناسب والروابط، فإن البحث يضع البورصة الاجتماعية بدقة ضمن مبادئ الشريعة الإسلامية ويتأكد من الحاجة إلى إنشاء بورصة اجتماعية إسلامية. وبناء على ذلك، صاغ البحث اقتراحات حول العناصر القانونية والتنظيمية والشرعية اللازمة لإنشاء بورصة اجتماعية إسلامية رقمية وهياكلها التشغيلية.

Authors: Quiroz Marchant Iván , Gutiérrez Caro Braulio
Published: June 2024

Se evalúa dos experiencias de plantación de hualo (Nothofagus glauca), una donde se contrasta plantas establecida con y sin cobertura de dosel remanente, y otra en que se evalúa el efecto de subsolado. Ambas experiencias se analizan con el objeto de confirmar la utilidad de las mediciones de fluorescencia de clorofila (expresada en el parámetro Fv/Fm) como indicador de estrés, que contribuye a explicar resultados de crecimiento, vigor y supervivencia de las plantas.
Los resultados mostraron que las plantas sin cobertura presentaron menores niveles de estrés y mayor vigor en comparación con las que estaban bajo cobertura. En cuanto al subsolado, las plantas en suelo subsolado mostraron mejor desempeño en términos de supervivencia, crecimiento en altura y diámetro de cuello, y menores niveles de estrés.
La fluorescencia de clorofila, utilizada como indicador de estrés, demostró ser consistente con las observaciones de vigor en terreno y con el desempeño general de las plantas.

La Araucaria araucana, una especie emblemática de los bosques de Chile y Argentina, enfrenta una fuerte presión debido al cambio climático, lo que la ha predispuesto al daño foliar de la araucaria (DFA). Esta enfermedad afecta al 85% de las poblaciones chilenas y ha llevado a cambiar su estado de conservación a "en peligro de extinción" en la Cordillera de la Costa. Para conservar esta especie, se inició un programa de migración asistida, recolectando semillas de 458 individuos representativos de sus poblaciones en las Cordilleras de la Costa y Los Andes. Las semillas fueron cultivadas manteniendo la identificación familiar y se estableció una colección de plantas en 54 hectáreas distribuidas en seis unidades de conservación. Estas unidades, estructuradas como ensayos de progenie y procedencia, se instalaron en áreas de acogida tanto dentro como fuera de la distribución natural de la araucaria. Las áreas de acogida fueron seleccionadas mediante proyecciones climáticas para los próximos 50 y 70 años, garantizando condiciones idóneas para el desarrollo de la araucaria y minimizando el estrés bioclimático, que incluye estrés térmico por temperaturas extremas y estrés hídrico estival. El objetivo del programa de migración es salvaguardar el potencial evolutivo de la araucaria y establecer poblaciones base para futuras iniciativas de restauración utilizando el material genético rescatado.

Epistemic Lexical Bundles in Applied Linguistics Literature Reviews: A Corpus-Based Study of Expert and Student Writing
Authors: Tarmizi Muna Liyana Mohamad , Aziz Hussin Anealka
Published: June 2024

Lexical bundles, recurring multiword sequences, are often regarded as the foundational elements of discourse, serving crucial functions in language. Acknowledged as integral to fluent linguistic expression, these bundles play a pivotal role in conveying evaluations, opinions, and attitudes in both spoken and written communication. Despite their significance in articulating personal and professional assessments, the utilization of lexical bundles in the review genre remains a relatively unexplored area of study. This paper aims to explore the use of epistemic lexical bundles within the context of applied linguistics literature reviews, comparing two distinct groups of writers: experts and student writers. Through a corpus-based contrastive analysis conducted on the Expert Literature Review Corpus (ELRC) and the Malaysian Literature Review Corpus (MLRC), four-word lexical bundles were automatically generated using Wordsmith Tools 6.0 (Scott, 2012). The identification of Epistemic Personal and Impersonal lexical bundles followed the categorizations of Epistemic Stance Bundles proposed by Biber et al. (2004). The findings reveal noticeable differences in the preferences of experts and student writers regarding the use of Epistemic bundles, particularly the absence of subcategory Personal bundles in the learner corpus. However, some shared bundles suggest a certain degree of alignment in writing style, vocabulary, and expression of epistemic stance between the two groups when reviewing existing literature. These insights carry implications for academic writing, emphasizing the necessity for further exploration in this domain.

The oceans are one of the final destinations for the vast majority of plastic waste; in this sense, particles smaller than 5 mm, classified as microplastics (MPs), represent an environmental challenge with global impact on several ecosystems. The work evaluated the presence of MPs in marine waters off the northern coast of Santa Catarina (Brazil), addressing sampling procedures, opening, characterization, and polymer identification. A low-cost equipment developed with easily accessible materials was tested in the sampling, showing excellent results in terms of buoyancy, stability, and mechanical strength. The concentration of MPs obtained in the study was 0.01 MPs per m3. The particles found were analyzed by stereomicroscopy and classified according to morphological aspects in relation to shape into fragments 58,00%, films 25,00%, and lines 17,00%, and regarding the aspect related to color, blue was predominant. The characterization and polymeric identification was performed by Fourier transform infrared spectroscopy coupled to the total attenuated reflectance module (FTIR-ATR). The types of polymers identified were: polyethylene 33,33%; polypropylene 25,00%; butadiene-styrene copolymer 25,00%, and cellulose 16,66%. The work contributed to the evaluation of an area not yet studied in relation to the presence of MPs in marine waters, while at the same time described in detail the methodologies for analyzing microplastics proposed in the specialized literature.
Media and Conservation of Art: With Special Reference to the Dying Legacy of Indore Gharana
Authors: Pandey Pragati
Published: June 2024

Indian classical music has its roots deeply embedded in the Gharana Culture. One such prominent gharana that stamped its authority through the stalwarts like Ustad Amir Khan Sahab was Indore Gharana. The gharana once reached the zenith of popularity with the singing style and the beautiful compositions amongst the listeners of all age. The unique aspect of this singing style was that it was aesthetically beautiful and easily adaptable and that made it a popular style amongst everyone. The gharana is however currently going through a dark phase and is at the brink of getting extinct. The gharana is today nothing more than a dying legacy. It is unfortunate to note that a tradition worth centuries is at the brink of death. The study therefore revolves around the factors that led to the downfall of this rich legacy. This study is relevant for mapping the causes that can probably lead to the downfall of other prominent gharana as well. The primary data is collected through interviews of the current Indore Gharana artists. The findings suggest that the lack of interest of academia and popular musicians and industry has been one of the cause of the downfall of this tradition. Lack of a popular figure within the gharana of the stature of Ustad Amir Khan Sahab also contributed to the fall of the gharana.

Solar e-rickshaw is a new means of transport and advanced technology that blends solar energy with mechanics. In simple words, a solar e-rickshaw is a three-wheeler powered by solar energy, suitable for short distances (Mulhall et al., 2010). Solar-powered e-rickshaws can support the daily operations of the drivers, helping them overcome range restrictions and make more money as they can avoid charge-wait periods during work hours. These solar e-rickshaws are also clean, environment friendly, sustainable energy. This study aimed to identify the lack of knowledge due to communication gaps in spreading awareness regarding advantages of solar e-rickshaw, which has led to less usage of e-solar rickshaws that has the potential to enhance the performance and energy efficiency for achieving environmentally sustainable transportation. This study is with special reference to Gurugram city in India. The methodology used for this study is in-depth interviews using semi-structured questionnaire and purposive sampling. The outcome of the study indicates that measures are needed to communicate and educate the e-rickshaw drivers and owners on its solar version and its benefits, for the solar e-rickshaw to come to mass use and acceptance.

Entrepreneurship is entering into business opportunity and creating employment in economy. It boosts the nation’s economy and financial aspect of individual. With growing population, unemployment, Entrepreneurship can tackle this biggest challenge for India via creating more and more employment in their firms. Entrepreneurs are growing tremendously with record of 14.4% Entrepreneurial Activity rate in 2021 as compare to 5.3% in 2020 (Global Entrepreneurship Monitor (GEM), n.d.)but the participation of women in entrepreneurship is not going at that par. Women’s share in Entrepreneurship in India is 13.76%.Entrepreneurship is affected by External and Internal Environment of Individual. Externally Government policies, Economical status of Nation, Bank finance availability, Market trend etc which are not in control of Individual. Internally entrepreneur’s behaviours, stress taking capacity, Intelligence etc which are in the control of Individual. Behaviour pattern of entrepreneurs, is affected by their cognitive and emotional intelligence.(Checa & Fernández-Berrocal, 2019) Both intelligences are interconnected, but EI could influence emotional task performances independently of IQ( Alkozei et. al., 2018).This needs a thorough understanding of the Emotional aspect for controlling Entrepreneur’s actions. we have focussed our review on Emotional aspect of Entrepreneur. We have reviewed- “peer reviewed” research papers, articles, books published in last 20 years. Our source of research papers is Google Scholar, EBSCO, Research gate, J-Gate. We found the Positive relationship between Emotional Intelligence and Entrepreneurial Orientation (Khatoon,2013) but it has not been studied on women entrepreneurs (Pradhan & Nath, 2012). Most of the researchers have study the concept on students, Managers, and small-micro firm entrepreneurs from other countries. No empirical research on relationship between Emotional Intelligence and Entrepreneurial Orientation in India we have found, which is required to study, to prove whether the correlation between them is applicable to India and how this correlation affects the Women Entrepreneurs.

In India, the ‘Digital India’ drive and ‘Demonetisation’ have catalysed the digital revolution in the country. India became the second fastest growing digital economy across the world due to growing internet penetration, robust IT sector, rising smartphone, and demographic dividend. Although, demonetisation has given a big thrust to digital adoption in the country. The present study attempts to explore and examine the demand-side effects of demonetisation on digital adoption in the long run by using paired sample t-test. The findings reveal that demonetisation have significantly affected the digital adoption, usage of plastic money and m-wallet in the country.
POLİTİKA TRANSFERİ ÇERÇEVESİNDE TANZİMAT DÖNEMİ MÜLKİ İDARE SİSTEMİ LİTERATÜRÜ ÜZERİNE BİR DEĞERLENDİRME
Authors: Özdemiray Sema Müge
Published: June 2024

Osmanlı Devleti 19. yüzyılda, mülki idare sisteminde yapı ve işleyiş anlamında belirgin bir değişime sahne olmuştur. Ancak ilgili literatürde, yaşanan değişimin neden ve nasıl gerçekleştiği konusunda bir uzlaşı söz konusu değildir. Süreci Osmanlı’nın iç dinamikleri ve devlet içi faktörler üzerinden okuyarak, değişimin gönüllülük esasıyla gerçekleştirildiğini savunan çalışmalar olduğu kadar; Avrupalı devletlerin baskılarına vurgu yaparak değişimin zorunluluktan kaynaklandığını ve Tanzimat sonrası oluşan sistemde Fransa’nın model ülke olduğunu savunan çalışmalar da bulunmaktadır. Bu çalışma; ilgili dönemi değerlendiren temel eserlerden yola çıkarak, teorideki durumun politika transferi bakış açısıyla ifade ettiği anlamı ortaya koyma noktasında literatüre mütevazi bir katkı sağlamayı amaçlamıştır. Bu amaçla çalışmaya dahil edilen eserler ışığında; ilgili yazında, Tanzimat Dönemi’nde mülki idareye yönelik kamu otoritelerini politika transferine iten nedenlerin ne olduğu ve buna bağlı olarak transferin türünün nasıl değerlendirilebileceği, neyin transfer edildiği ve transferin derecesinin ne olduğu sorularına net bir cevap bulmanın güçlüğü ortaya konmuştur. Buna karşılık, ilgili dönemde politika transferinin var olup olmadığı ve aktörlerinin kimler olduğu sorularına ise daha tutarlı bir cevap verilebileceği sonucuna ulaşılmıştır.
MİKROPLASTİKLER VE CANLILAR ÜZERİNE ZARARLI ETKİLERİ
Authors: Temel Hamdi
Published: June 2024

"In recent years, our soils, rivers, seas, oceans and even the air we breathe have begun to be polluted with microplastics. Every day, it is increasingly evident that microplastics, ranging in size from 1 micrometer to 5 millimeters, are adversely affecting our environment and organisms. New research and findings regarding microplastics emerge daily. Microplastics have been found everywhere, from human blood to the air we breathe, and are particularly prevalent in almost all fish species living in oceans. A study emphasized the prevalence of microplastics, suggesting the possibility of consuming microplastics equivalent to the size of a credit card weekly. Recent studies indicate that microplastics can breach the blood-brain barrier in animals, reaching brain tissue and potentially affecting the human brain as well. This finding suggests that organisms may face even greater challenges in the future. This study examines research on the harmful effects of microplastics on living organisms. As a result, serious research should continue on the damages caused by microplastics, solutions should be proposed, mandatory implementations should be put into practice, the cost of glass containers and materials that can be used instead of plastic should be reduced, and efforts to develop alternatives should be increased."

"There are many gaseous and particulate matter pollutants in the air we breathe. The main gaseous pollutants with defined limit values for human and environmental health are SO2, NOx, CO and O3, and the main particulate pollutants are PM10 and PM2.5. PM10, SO2 and NOx concentrations show a continuous decreasing trend worldwide due to improved technologies and international and national emission reduction measures. On the other hand, fine particles (PM2.5) concentrations do not show a common trend worldwide, but ultrafine particles either remain constant or show an increasing trend despite the emission reduction measures taken in general. Secondary aerosols consisting of organic and inorganic compounds constitute a significant portion of fine particles all over the world. In the monitoring of secondary aerosols, the most prominent trace parameters will be the numerical values of ultrafine particles and ions. The fact that air pollution differs in terms of content and concentration in each region requires the evaluation of different air pollution abatement plans."
