Estudios en restos óseos humanos en Patagonia Austral: de la morfología clásica a la morfometría geométrica
Authors: D'Angelo del Campo Manuel Domingo , Guichón Ricardo Anibal , González Martín Armando
Published: August 2023

A finales del s. XVIII, pero fundamentalmente durante los ss. XIX y XX, se realizan los primeros  trabajos craneométricos acerca de las poblaciones que habitaron Patagonia Austral (PA). En esta  región, los primeros abordajes de corte tipologista dejaron paso a otra corriente centrada en la  estadística multivariante y la síntesis evolutiva a partir de la década de 1980. A fin de abordar cómo  ha cambiado la bioantropología de PA a lo  largo del tiempo se realizó un diagnóstico acerca  de la información que contienen 75 publicaciones  morfométricas, desde el año 1937 hasta el año  2020. Los resultados muestran que, en las últimas  décadas, se ha producido un incremento  exponencial de las publicaciones sobre las  poblaciones nativas de PA, centrándose  fundamentalmente en el estudio craneano,  observándose una preponderancia del abordaje geométrico en la última década. Sin embargo, el  trato de los metadatos primarios y secundarios es  deficiente; muestra de ello, son los términos  utilizados para definir la procedencia de las  muestras, los cuales son vagos y poco precisos. El  conocimiento acerca de la disposición de los  restos esqueléticos y la información aportada  acerca de la datación suele ser insuficiente o  difusa. Las deficiencias en la comunicación de datos y metadatos conducen a dificultades en la  replicabilidad y verificabilidad, promoviendo redundancias, baja eficiencia, e incidiendo en una  mala gestión de fondos públicos para investigación. Esperamos que el uso de bases de datos bibliográficas y morfométricas, así como  diagnósticos periódicos como este ayuden a que la comunidad bioantropológica comience a  reportar en sus publicaciones información  relevante asociada a los individuos analizados.

Published: August 2023

El objetivo fue realizar un análisis histórico-bibliométrico de Educación Física y Ciencia durante el periodo 1995-2019, centrado en los aspectos de productividad, materias y colaboración. Para ello, se consultaron todos los documentos publicados en la revista, recogiendo su información bibliográfica en el programa Endnote X9, junto con su campo de conocimiento, número de autores, afiliación y país de los autores. Los datos fueron exportados al programa Excel 2019 para su análisis estadístico. También se calcularon los artículos individuales, en coautoría, el promedio de autores/artículo y el porcentaje de colaboración. Se encontraron 281 documentos, publicados principalmentedurante el periodo 2015-2019. La Sociología fue el campo de conocimiento más representado (28,5%). El periodo 2015-2019 presentó un aumento significado en la cantidad de autores, instituciones, países colaboradores y porcentaje de colaboración. En conclusión, Educación Física y Ciencia ha pasado por dos etapas. La primera (1995-2014) estuvo caracterizada por una publicación irregular, producida fundamentalmente en la UNLP y reflejando los cambios sociales y políticos de la UNLP y la Educación Superior en Argentina. En la segunda etapa (2015-2019) se produjo una apertura editorial que conllevó el crecimiento de la revista, así como la mejora de su visibilidad y el aumento de colaboraciones.
Derecho a la recreación: explorando discursos y prácticas a nivel local
Authors: Pérez Alejandra , Devita Daniel
Published: August 2023

Las reivindicaciones en materia de derechos humanos se vuelven cada vez más complejas incorporando distintas dimensiones de la vida social. El disfrute del tiempo libre y la recreación en tanto derecho humano no solo ha sido objeto de internacionalización sino también de constitucionalización. El derecho a la recreación comprendido en los discursos de los derechos económicos, sociales y culturales (DESC), nos plantea una relación bidimensionalmente conflictiva entre su reconocimiento simbólico formal y su operatividad o garantía de ejercicio. En este contexto nos hemos planteado el proyecto de investigación titulado “Derecho a la Recreación: ¿sólo una cuestión declarativa? Discusiones entre normas y prácticas”. En este artículo exponemos dos líneas temáticas desarrolladas en el marco de dicho proyecto: (a) el reconocimiento de la recreación como derecho a partir de los discursos1, y (b) las prácticas recreativas en clave de derecho. El método utilizado se corresponde con el abordaje cualitativo y la implementación de distintos dispositivos conversacionales grupales e individuales aplicados a actores del quehacer recreativo local.

Published: August 2023

A research study was conducted to determine the effect of different P levels and seeding rates on the growth, phenology, and yield of wheat. The experiment used a randomized complete block design with split plot arrangement and four replications. The main plots consisted of six seeding rates, ranging from 50 to 175 kg/ha, while the sub-plots received six different P levels, ranging from 50 to 200 kg/ha. In consecutive years, the study revealed significant effects of phosphorus levels, seeding rates, and their interaction on various growth characteristics and yield parameters of wheat. These included days to 50% heading and 50% maturity, leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), net assimilation rate (NAR), and grain yield (GY). Phosphorus (P) level of 140 kg/ha resulted in the highest CGR, NAR, and GY in both years of the study. At a seeding density of 125 kg/ha, similar findings were observed, with the maximum CGR, NAR, and GY recorded. The highest interaction values for CGR, NAR, and GY were achieved with the combination of 140 kg P/ha and a seeding rate of 125 kg/ha. By utilizing a seed rate of 175 kg/ha and a P level of 200 kg/ha, the study revealed the highest values for LAI and LAD. Additionally, the maximum protein content was observed in treatments where seeds and P were applied at 50 and 200 kg/ha, respectively. In summary, the study provided conclusive evidence that the application of suitable seeding rates and P levels can yield significant improvements in the growth, phenology, and yield of wheat. The findings could be beneficial for farmers and researchers in improving wheat production.

Aims

Hypoalbuminemia was extensively used to diagnose malnutrition in older adults. Malnutrition was associated with mortality in elderly patients with cardiovascular diseases. The relationship between hypoalbuminemia and clinical outcomes in elderly patients with nonischemic dilated cardiomyopathy (NIDCM) remains unknown.

Methods

A total of 1058 consecutive patients with NIDCM (age ≥60 years) were retrospectively enrolled from January 2010 to December 2019. Univariate and multivariate analyses were performed to assess the association of hypoalbuminemia with clinical outcomes.

Results

Patients with hypoalbuminemia were older (69.29 ± 6.67 vs. 67.61 ± 5.90 years, P < 0.001) and had higher prevalence of in-hospital and long-term death than those without (6.9 vs. 1.7%, 50.7 vs. 35.2%, P < 0.001). Logistic regression analysis showed that hypoalbuminemia was significantly related to in-hospital death [odds ratio (OR): 4.334, 95% confidence interval (CI): 2.185–8.597, P < 0.001]. Kaplan–Meier survival analysis showed that patients with hypoalbuminemia had worse prognosis than those with nonhypoalbuminemia (log-rank χ
2 28.96, P < 0.001). After adjusting for age, serum creatinine, HDL-C, AST/ALT hypoalbuminemia, LVEF and diabetes, hypoalbuminemia remained an independent predictor for long-term death (hazard ratio 1.322, 95% CI 0.046–1.670, P = 0.019).

Conclusion

Hypoalbuminemia was associated with increased risk of in-hospital and long-term mortality in elderly patients with NIDCM.
Comparative evaluation of mechanical properties of short aramid fiber on thermoplastic polymers
Authors: Arı Ali , Bayram Ali , Karahan Mehmet , Arslan Orhun
Published: August 2023

This study investigated the mechanical performance of short aramid fiber on polypropylene, polyethylene, polyamide 6, and polyamide 12. Extrusion, press molding, and CNC cutting methods were used in the production of composite samples. Tensile, three-point bending, drop weight and hardness tests of the composites were carried out. As the fiber volume fractions increased, the mechanical properties of the composites improved, but the most efficient fiber fractions for each matrix changed. To analyze the performance of the fibers in the matrix on the composites, scanning electron microscope (SEM) images of the fractured surfaces as a result of tensile and drop weight tests were examined. As the fiber volume fractions increased, the fiber deformation increased, and as a result, the mechanical performance of the composites was adversely affected. Analysis of variance (ANOVA) and F test were performed using signal/noise values to analyze in detail the effect of experimental parameters on output values. Finally, the results of a regression equation model were compared with the experimental readings. It was found to be in good agreement with the model and the results of the experiment.

Tüm saf hatlarda artan yaşla birlikte FPD skorlarında artış görülmüştür. Canlı ağırlıkların daha yüksek olduğu baba hatlarında (B1 ve B2) 14 haftalık yaşta daha düşük FPD skorları görülürken, 42 haftalık yaşta ana hatlarından (A1, A2 ve A3) daha yüksek olmuştur. Ana hatlarında 30 ve 42 haftalık yaşlarda baba hatlarına göre daha yüksek yumurta verimi ve kuluçkalık yumurta verimi elde edilmiş ve hatlar arasındaki farklılıklar önemli bulunmuştur (P<0,01). Yumurtlama döneminde A1, A2, A3, B1 ve B2 saf hatlarında gerçekleşen kuluçkalık yumurta oranları sırasıyla %98,55, %96,68, %97,75, %96,39 ve %97,23 olarak belirlenmiştir. Saf hatlarda yumurta ağırlıkları bakımından farklılıklar önemli bulunmuştur (P<0,01). Döllülük oranları bakımından genotipler arasında önemli farklılıklar belirlenmiştir (P<0,01). Ebeveynlerin 14, 20, 30 ve 42 haftalık yaşlarındaki canlı ağırlıkları ile FPD skorları arasında belirlenen korelasyon katsayıları sırasıyla 0,70, 0,64, 0,72 ve 0,67 bulunmuştur (P<0,01). 42. hafta yumurta verimi ve kuluçkalık yumurta verimi ile FPD değerleri arasında -0,56 ve -0,54’lük korelasyon katsayıları belirlenmiştir (P<0,01). Döllülük oranları ile canlı ağırlıklar arasındaki korelasyon katsayıları önemli bulunmamıştır. Canlı ağırlıklar ile yumurta verimi ve kuluçkalık yumurta verimi arasındaki önemli düzeyde negatif yönlü korelasyonlar bulunmuştur (P<0,01). Sonuç olarak, CA ve FPD düzeyleri baba hatlarında daha yüksek bulunurken, KYV bakımından ana hatları üstünlük sağlamıştır. Artan CA ile FPD düzeyindeki artış üreme performansındaki düşüşe katkı sağlamış olsa da döllülük oranı üzerinde olumsuz bir etki ortaya çıkmamıştır.

The AMNOG is known to be a ‚learning system‘. But in some cases the system is being taught a lesson. For example, by the Federal Social Court (BSG) in February 2023 in the so-called Regadenoson ruling: the G-BA‘s decision on this active substance was declared invalid. This (in brief) because of the insufficient consideration of the soloist status and because of the consideration of medicinal products in off-label use as appropriate comparative therapy (ZVT).

Estudos demonstram a eficácia de bioinseticidas no controle do mosquito Aedes aegypti.  Neste sentido, este estudo teve como objetivo avaliar o efeito larvicida de extratos de Allamanda cathartica (L.) Apocynaceae (alamanda), Chrysanthemum morifolium (L.) Asteraceae (crisântemo) e de Cinnamomum verum (L.) Laureaceae (canela doce) sobre larvas do mosquito A. aegypti. Para a produção dos extratos os materiais vegetais desidratados (50 g) foram extraídos com água (1000 ml) por decocção e maceração por cinco dias com etanol (90%). Os extratos aquosos e hidroalcóolicos liofilizados foram diluídos em água deionizada nas concentrações de 100, 500 e 1000 μg/ml e introduzidos em recipientes (n =3) contendo 20 larvas de A. aegypti no terceiro/quarto estágio larval. A atividade larvicida foi avaliada 72 h após os tratamentos. Os extratos aquosos de C. verum nas concentrações de 100, 500 e 1000 μg/ml apresentaram média de 83,86% de eficiência. Contudo, os extratos aquosos e hidroalcoólicos de C. morifolium apresentaram forte atividade larvicida com 100% de eficiência em todas as concentrações testadas. Os achados deste estudo revelam que os extratos de C. morifolium e C. verum são promissores larvicidas naturais e podem auxiliar no controle do mosquito vetor de arboviroses como, a dengue, febre amarela, Zika e chikungunya.

Urban afforestation consists of arboreal plant elements present in the city and is of fundamental importance for the quality of life of citizens. The study of the urban green area aims to support a better planning of a city seeking an environmental balance so that in the future it will minimize the effects caused by urbanization. Understanding the allometric patterns that govern the growth of trees in public areas is part of modern urban planning. The aim of the study was to determine the allometric patterns of trees located in public green areas in the city of Boa Vista, Roraima. The study was based on adult individuals with a diameter at breast height (DBH) greater than or equal to 10 cm, dispersed in three public squares and central flower beds of two avenues. In the floristic survey, there was a higher relative frequency of the species Licania tomentosa with 45.10%, Handroanthus impetiginosus  with 26.65% and Pachira aquatica with 7.51% of the individuals. The best allometric relationships based on the sampling sites were between stem diameter and crown area (R² = 0.63 ) and total height and stem height (R² = 0.50). Our results reflect different allometric patterns between the sampled public areas because each of the sites is provided by cultivation of trees of different species, planting ages and management methods, generating different growth models. Our study is unprecedented and configures itself as one of the bases for discussions on the importance of afforestation within the concepts of environmental services provided by urban green areas.

An organization or sector now needs to own a three-phase induction generator. The condition in which the factory was in operation forced the 3-phase scraper conveyor induction motor at PT Citra Sawit Lestari to continue to move the palm oil that is transported from the truck to the thresher. This process continues as long as the factory operates Under these conditions the load obtained by the 3-phase scraper conveyor induction motor affects the condition and performance of the induction motor This research was conducted on a 3-phase scraper conveyor induction motor using a quantitative approach that allowed the company to find out the causes of the reduced performance of 3-phase induction motors and find out the actions that must be taken so that the performance of 3-phase induction motors remains optimal Based on this research, it was concluded that changes in load could affect the performance of a 3-phase induction motor and the MAPE value of motor torque was 0.038%, motor power is 0.0008%, and rotational speed is 0.025%. With an average MAPE percentage value of less than 10%, this indicated that the performance of the 3-phase induction motor was still very good.

Disturbance caused by the touch of trees and animals is the cause of disruption of electricity distribution services that are most widely reported in all PLN service units as a result of the large number of animals playing around the SUTM network. The purpose of this research is to design a tool/component of climbing barrier on the Treck Schoor Feeder 5B3, ULP Painan-UP3 Padang in an effort to prevent the number of external disturbances. The research was conducted using a case study type by counting the number of animal disturbances that occurred in the medium voltage airways (SUTM). The research location is in the 20 kV medium voltage distribution channel (SUTM) at Feeder 5B3, ULP Painan-UP3 Padang. The impact of the work of installing animal climbing barriers on the Treck Schoor in the F5B3 feeder has decreased by 100% (very significant), i.e. ZERO disturbances in March-May 2022.
Calculation of Joule-Thomson and isentropic expansion coefficients for two-phase mixtures
Authors: Oumarou Ali Ababakari , Broseta Daniel , Nichita Dan Vladimir
Published: August 2023

Joule–Thomson (JT) and isentropic expansion coefficients describe the temperature change induced by a pressure variation under isenthalpic and isentropic conditions, respectively. They are commonly used to model a variety of processes in which either fluid compression or expansion is involved. While a lot of work has been devoted to inferring the JT coefficient from an equation of state when the fluid is a single phase, little attention has been paid to multiphase fluids, where phase equilibrium has to be taken into account; previous work has only addressed the construction on the JT inversion curve. In the present paper, we describe and implement an approach to calculate these two coefficients for multi-component fluid systems, including when they form two different phases, liquid, and vapor, in thermodynamic equilibrium. The only ingredients are an equation of state and expressions for the ideal part of the specific heats of the fluid components. We make use of cubic equations of state, but any thermodynamic model can be used in the proposed framework. Calculations conducted with typical geofluids, some of them containing CO2, show that these coefficients are discontinuous at phase boundaries (where enthalpy and entropy variations exhibit angular points), as expected with any thermodynamic quantity built from first-order derivatives of state functions, and cannot be simply inferred from the coefficients of the liquid and vapor phases.

Published: August 2023

Across the globe, there has been increasing interest in the study of medicinal plants and its use in ailing various oral diseases including periodontal disease. Various antibiotics such as tetracycline, amoxicillin, penicillin, and metronidazole and antiseptics such as chlorhexidine are commonly used in periodontal diseases, but they have many side effects. While indigenous medicine has not only less side effects but can also be effective in regulating the systemic conditions that have been associated with periodontal diseases such as diabetes and cardiovascular diseases. These natural extracts contain phytochemical compounds which have anti-inflammatory property, prevent bleeding, and antimicrobial properties. Several plant extracts such as curcumin, green tea, and neem have shown promising results in the field of periodontics. However, in the current scenario, the biggest challenge is the significant gap in research and lack of information regarding its interaction with the oral tissue, mechanism of action, and side effects. This study gives an insight into the current use of available herbal medicines that have been readily used in dental treatment particularly periodontal disease. It also gives information regarding the availability of these drugs through various platforms. It can be concluded that indigenous remedies have potential benefits in controlling plaque and inflammation as adjuncts to daily oral hygiene in patients with periodontitis gingivitis.
Role of fibroblast growth factor 8 in different cancers
Authors: Ranjan Swati , Saini Abhinav , Yadav Savita
Published: August 2023

Fibroblast growth factor 8 (FGF8), a secretory protein of the FGF family, is highly expressed during early developmental stages. The early-stage expression of FGF8 and its isoforms is crucial for the normal development of organisms, while their expressions in adulthood are limited to the steroid hormone-targeting tissues. Interestingly, differential expression of FGF8 has been associated with the progression of various cancer types including breast, prostate, and ovarian cancers. Specifically, in gynecological cancers, the expression of FGF8 is regulated by steroid hormones. FGF8 isoforms, that is, FGF8a, FGF8b, FGF8e, and FGF8f act through different fibroblast growth factor receptors in different cancers through three main signaling pathways – MAP/RAS kinase, AKT/PI3, and PCLγ. This short review article discusses the structure and functions of FGF-8, along with its role in different cancers.
Doubly Tuned Exchange-Correlation Functionals for Mixed-Reference Spin-Flip Time-Dependent Density Functional Theory

Published: August 2023

It is demonstrated that significant accuracy improvements of MRSF-TDDFT can be achieved by introducing two different XC functionals for the reference Kohn-Sham DFT and the response part of calculations, respectively. Accordingly, two new exchange-correlation (XC) functionals of DTCAM-VEE and DTCAM-AEE were developed on the basis of the "adaptive exact exchange (AEE)" concept in the framework of the Coulomb-attenuating XC functionals. The values by DTCAM-VEE are in excellent agreement with those of Thiel's set (mean absolute error (MAE) and interquartile range (IQR) of 0.218 and 0.327 eV, respectively). On the other hand, DTCAM-AEE faithfully reproduced the qualitative aspects of conical intersections of trans-butadiene and thymine, and the NAMD simulations on thymine. The latter functional also remarkably exhibited the exact 1/R asymptotic behavior of the charge-transfer state of an ethylene-tetrafluoroethylene dimer, and the accurate potential energy surfaces along the two torsional angles of retinal protonated Schiff base model with six double bonds (rPSB6). The current idea can be also applied to other XC functionals as well as other variants of linear response theories, opening a new way of developing XC functionals.
Learning the Language of NMR: Structure Elucidation from NMR spectra using Transformer Models
Authors: Alberts Marvin , Zipoli Federico , Vaucher Alain C.
Published: August 2023

The application of machine learning models in chemistry has made remarkable strides in recent years. Even though there is considerable interest in automating common proce- dure in analytical chemistry using machine learning, very few models have been adopted into everyday use. Among the analytical instruments available to chemists, Nuclear Mag- netic Resonance (NMR) spectroscopy is one of the most important, offering insights into molecular structure unobtainable with other methods. However, most processing and analysis of NMR spectra is still performed manually, making the task tedious and time consuming especially for larger quantities of spectra. We present a transformer-based machine learning model capable of predicting the molecular structure directly from the NMR spectrum. Our model is pretrained on synthetic NMR spectra, achieving a top–1 accuracy of 67.0% when predicting the structure from both the 1H and 13C spectrum. Additionally, we train a model which, given a spectrum and a set of likely compounds, selects the one corresponding to the spectrum. This model achieves a top–1 accuracy of 96.0% when trained on 1H spectra.
Fine-Tuning Dual Single-Atom Metal Sites on Graphene Toward Enhanced ORR Activity
Authors: Xie Evan , Wang Xijun
Published: August 2023

The electrocatalytic oxygen reduction reaction (ORR) plays a crucial role in numerous energy and sustainability systems, such as fuel cells, metal-air batteries, and water electrolysers. It holds significant potential for renewable energy generation, transportation, and storage, heralding a cleaner and more sustainable future. Recent trends have shown increased use of single-atom catalysts (SACs), particularly metal-N4 moieties grown on graphene-based 2D materials, for enhancing ORR efficiency. However, the rational design of SAC for high-performance ORR faces challenges due to unclear structure-property relationships and the limits of conventional experimental trial-and-error approaches. In this study, we harnessed the power of the density functional theory (DFT) calculations, combined with cutting-edge machine learning (ML) techniques, to explore 144 SACs featuring dual interacting M1-N4 and M2-N4 moieties (M1, M2 = Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag Ir, Pt, Au), denoted as M1-M2, grown on graphene. Of all the catalysts we examined, Fe-Pd emerged as the top performer, achieving an impressive overpotential of 0.980 V in alkaline conditions — outperforming most previously reported SACs. Even more striking, 25 of the evaluated SACs surpassed the renowned Fe-N4 SAC in catalytic efficiency, including more economically viable alternatives like Fe-Ag. Venturing further, we developed three ML models that accurately predict the overpotentials of various M1-M2 SACs, showing their strong ability to capture the relationship between single-atom metal site properties and overpotential. These models provide useful navigation toolkits for the rational design of effective electrocatalysts. Our study sheds light on the path toward achieving efficient SAC-catalyzed ORR, contributing to a more sustainable and energy-efficient future.

Photocatalytic hydrogen production from water is a promising way to fulfill energy demands and attain carbon emission reduction goals effectively. In this study, a loop photoreactor with a total volume of around 500 mL is presented for the photocatalytic hydrogen evolution using a Pt-loaded polymeric carbon nitride photocatalyst under 365 nm irradiation in the presence of sacrificial reducing agents. The fluid flow pattern of the developed photoreactor was characterized experimentally and the photon flux incident to the loop photoreactor was measured by chemical actinometry. The system displayed exceptional stability, with operation sustained over 70 hours. A Design of Experiment (DOE) analysis was used to systematically investigate the influence of key parameters - photon flux, photocatalyst loading, stirring speed, and inert gas flow rate - on the hydrogen generation rate. Linear relationships were found between hydrogen evolution rate and photon flux and inert gas flow rate. Photocatalyst loading and stirring speed also showed linear correlations. Notably, the loop photoreactor demonstrated an external photon efficiency up to 17 times higher than reported in literature studies, while scaling the reactor size by a factor of 10.

The development and optimization of reliable polymerization methods are needed for the synthesis of degradable imine-based conjugated polymers, which are attractive materials for transient electronics. Direct arylation polymerization (DArP) has emerged as a sustainable and atom-economical synthetic method for the preparation of well-defined conjugated polymers. Compared to polymerization methods such as imine polycondensation or Stille cross-coupling polymerization which require monomer functionalization, direct arylation proceeds via C-H activation and thereby reduces synthetic complexities and toxic by-products. Here we report the first use of DArP for the synthesis of an imine-based indacenodithiophene (IDT) copolymer, p(IDT-TIT). Polymers prepared via DArP can result in branched or cross-linked polymer chains due to the reactivity of C-H bonds in the monomers. In this report, we demonstrate a systematic study focusing on the reaction conditions needed to prepare p(IDT-TIT) via DArP with tetramethylethylenediamine as a co-ligand. The degradable polymer is characterized via nuclear magnetic resonance spectroscopy, high-temperature gel permeation chromatography, and ultraviolet- visible-near-infrared spectroscopy. With the simplicity of monomer preparation and reaction conditions, we anticipate this efficient synthetic protocol will lead to higher synthetic adoption in the research community to aid the exploration of high-performance imine-based degradable materials.

Peraturan yang ditetapkan SMK Negeri 1 Muara Enim untuk mendapatkan beasiswa kurang mampu, maka diperlukan kriteria-kriteria untuk menentukan siswa yang akan terpilih untuk menerima beasiswa. Namun seringkali pendistribusian beasiswa tersebut tidak tepat sasaran, sehingga siswa yang lebih membutuhkan justru tidak memperoleh beasiswa. Hal ini disebabkan karena belum menggunakan alat bantu atau metode yang digunakan untuk menentukan penerima beasiswa. Oleh karena itu, diperlukan media atau sistem yang dapat membantu dalam pengambilan keputusan. Untuk membantu menentukan siswa yang layak menerima beasiswa dibutuhkan sebuah sistem pendukung keputusan menggunakan metode Simple Additive Weighting (SAW) berbasis Paas Cloud Computing. Sistem ini dibangun dengan menggunakan bahasa pemrograman PHP dan menggunakan PostgreSQL sebagai database dengan memanfaatkan layanan cloud yaitu Heroku untuk menyebarluaskan aplikasinya.

Sponsored or Autogestive Materialisation of Space: Urban Informality in Harare, Zimbabwe
Authors: Maunganidze Langtone , Faimau Gabriel
Published: August 2023

Urban spaces have been centres of social struggles and transformation the world over. With reference to selected urban informal settlements in Zimbabwe, the present article draws inspiration from Henry Lefebvre’s (1991) “autogestion” thesis and examines the extent to which urban spaces have been appropriated and materialised in order to cope with the emerging urban poly-crises, particularly a shortage of land for residential purposes in Harare. The study on which this article is based sought to establish the extent to which both the genesis and the persistence of informal settlements exemplified either a sponsored or the agential appropriation and materialisation of urban spaces. The article observes that what seemed to be “anarchistic” tendencies of informality and irregularity were actually the product of a systematic appropriation and materialisation by various actors for both economic and political expedience.

Bu çalışmada, kırmızı deniz makroalglerinden Laurencia obtusa (Hudson) J.V. Lamouroux, 1813’nın besin içeriğindeki mevsimsel değişimler ve ekolojik değişkenler ile olan ilişkisi incelenmiştir. Çalışma materyali Sinop kıyılarındaki üç farklı noktadan mevsimsel olarak toplanmıştır. Bu çalışmada kül ve yağ değerleri açısından en verimli dönemin sonbahar, protein açısından ise en verimli dönemin kış olduğu tespit edilmiştir. Sonbaharda saptanan ortalama kül (%26.26±6.75) ve karbonhidrat (%64.47±6.06) değerleri ile diğer mevsimlere ait değerler karşılaştırıldığında farklar istatistiksel olarak önemli bulunmuştur (p<0.05). Deniz suyunun fizikokimyasal parametreleri ile besin kompozisyonunu arasında yapılan korelasyon analizine göre fizikokimyasal parametrelerden tuzluluk, pH, iletkenlik ve yoğunluk ile sıcaklık arasında pozitif bir korelasyon olduğu tespit edilmiştir. Ayrıca tuzluluk, elektriksel iletkenlik ve çözünmüş madde arasında da pozitif korelasyon gösterdiği saptanmıştır. Biyokimyasal parametrelerin korelasyonu incelediğinde sadece iletkenlik ile kül oranı arasında pozitif ve iletkenlik ile karbonhidrat oranı arasında negatif bir korelasyon tespit edilmiştir. Bu çalışma sonucunda elde edilen verilerin Laurencia obtusa’nın en kullanışlı dönemlerinin tespitinde önemli bir veri kaynağı olacağı düşünülmektedir.

We derived minima times from the transit curves of star-planet systems, Kepler-412, Kepler-422, Kepler-427 ve Kepler-435 observed by Kepler space telescope, using the Kwee - van Woerden method and Gauss function fitting. We examined the O-C diagram of each system separately, modelled them with linear and quadratic functions. We obtained that linear models give best fit for O-C distributions. We presented updated light elements of systems and concluded that O-C diagrams of systems can best be represented by the linear model.

Published: August 2023

In this study, the performance of several classification algorithms that are used to separate the H → ττ signal from background is investigated. The data set came from the publicly available ATLAS data, which was utilized for the Machine Learning (ML) competition. The data was obtained from a full ATLAS simulation and originated from proton-proton collisions. There are 250 thousand events in the data set, and 70% of them were used to train the algorithms. The primary objective of this research is to identify the signal events from the background events by using various ML methods in the context of high-energy physics. In order to discover a solution to the binary classification problem that was discussed earlier, six distinct classification algorithms were utilized. This article also compares the performance of these classification algorithms, including Linear Support Vector Machines (SVM), Radical SVM, Logistic Regression, K-Nearest Neighbours, XGBoost Classifier, and the AdaBoost Classifier. The best results were obtained using the XGBoost Classification method, which had an AUC of 0.84 ± 1.9 x 10-3 followed by the AdaBoost Classifier with an AUC of 0.82 ± 2.5 x 10-3.
