Authors: Rege Musa Ganya , Zezi A. U. , Maiha B. B. , Ahmed A. , Kolawole T. O.
Published: February 2025

Nymphaea lotus (Linn), an herbaceous aquatic plant from the Nymphaeaceae family, is widely utilized for its therapeutic properties. This study evaluates the phytochemical composition and acute toxicity of the methanol leaf extract and its aqueous residual and n-Butanol fractions in rats and mice. Phytochemical screening revealed the presence of various bioactive compounds; the quantitative determination of the bioactive constituents was carried out using Spectrophotometric analysis which revealed the aqueous residual fraction rich in tannins and the n-Butanol fraction rich in flavonoids. Acute toxicity tests, following OECD 425 guidelines, indicated that the LD50 is above 5000 mg/kg, confirming the non-toxic nature of the extract and fractions. Hematological analysis and histopathological examinations of major organs (stomach, intestine, kidney, and liver) showed no significant differences between treated and control groups. The findings support the plant’s safe use in traditional medicine and highlight its potential for further pharmacological research.

Kettős közigazgatás a hódoltságban : Mezőtúr helyzetének vizsgálata oszmán-török források alapján
Authors: Öner Erika
Published: February 2025

A tanulmány a 16–17. századi Mezőtúrt vizsgálja a török hódoltság
korában. Ebben az időszakban az oszmán hatalom a Magyar Királyság
középső területeit irányította. A megszállt területen belül, a kettős adóztatás ellenére, Mezőtúr megőrizte stabil mezővárosi mivoltát, és jelentős
kereskedelmi központként működött. A város egy fontos kereskedelmi
útvonal mentén feküdt, ami hozzájárult gazdasági fellendüléséhez és piaci szerepének megerősödéséhez. A szerző bevezetésként elméleti keretet
nyújt, amelyben összefoglalja a mezőváros (oppidum) sajátosságait, valamint bemutatja az oszmán közigazgatási egység, a náhije működését. A
kutatás alapját oszmán-török nyelven íródott levéltári források képezik.
Az elsődleges cél a mezővárosi és a náhije-rendszer közötti hasonlóságok és különbségek feltárása, valamint az Alföld más mezővárosaival való összevetés. A források betekintést nyújtanak abba is, hogy miként zajlott a mindennapi élet Mezőtúron a reformáció terjedése idején, amikor
a város és környéke oszmán uralom alatt állt. A tanulmány továbbá bemutatja, hogy az oszmán közigazgatás milyen módon gyakorolta ellenőrzését a térség felett. Az oszmán hatóságok szigorúan felügyelték az adóbeszedést, bérbe adták a legelőket és halastavakat, kijelölték a határokat,
biztosították a nagyvásárok zavartalan lebonyolítását, valamint a helyi
lakosok számára pallosjogot biztosítottak városaik és állataik védelmére.

Authors: Selamzade Fuad , Ersoy Yusuf , Tehci Ali
Published: February 2025

Purpose: This study aims to measure the carbon emission activities of Turkey, Azerbaijan, Kazakhstan, Kyrgyzstan and Uzbekistan and evaluate them from a green logistics perspective.
Method: Within the scope of the research, efficiency analyses were conducted using the output-oriented Data Envelopment Analysis (DEA) constant returns to scale (CRS) model and the super efficiency CRS DEA model. The input and output variables used in the research were obtained from the World Bank website.
Findings: In the research, the efficiency scores of the relevant countries were determined. It was determined that the efficiency scores of the countries were generally above 50%. The ranking of the efficient decision-making units among themselves was carried out with the super efficiency CRS DEA model. Some potential improvement suggestions were presented for the decision-making units that were not efficient.
Originality: In order to leave a livable world to future generations, green energy production should be supported and Carbon Dioxide (CO2) emissions should be kept under control. Therefore, the efficiency assessment of countries' CO2 emissions is of vital importance. This study has an original feature because the CO2 emission activities of the Turkish Republics were carried out using the super efficiency CRS DEA model. This study can provide guidance to those who will conduct research on this subject and to country leaders.
A Model for Vehicle Routing Problem under Returns and Emission Consideration in B2C E-Commerce Logistics
Authors: Belbağ Sedat
Published: February 2025

Purpose: With the widespread use of the Internet, electronic commerce allows customers to purchase products from the virtual stores of businesses instead of physical stores. This study addressed a mixed-integer linear programming model for a vehicle routing problem under returns and emission considerations in B2C e-commerce logistics.
Methodology: This study proposes a mathematical model to solve a variant of the vehicle routing problem. The objective is to minimize the fuel consumption cost, penalty cost for unmet demand of returned items, and fixed cost for operating a vehicle. A clustering-based solution algorithm has been introduced to solve large-sized instances within reasonable solution times.
Findings: The numerical analysis for the base case shows that the suggested model can assist decision-makers in coordinating forward distribution and reverse collection decisions within the context of sustainable e-commerce logistics. The result of the adjusted model for minimizing emission shows that a reduction of nearly 17% in total emission amount can be achieved, however, the adjusted model postpones all demand for the collection of returned items. Furthermore, the cluster-based solution approach causes a considerable decrease in solution time while providing promising solutions.
Originality: This study represents a contribution to the existing literature on the subject by considering: i) emission to determine effects on the vehicle routing problem, ii) the postponement of the collection of returned items due to the limited delivery time, iii) proposing the clustering-based solution approach to tackle with larger-sized problems.

Published: February 2025

This study develops a mathematical model to evaluate the impact of fuel subsidy policies on rice production in Niger State, Nigeria. Agriculture is crucial to Nigeria’s economy, and rice is a staple food and source of livelihood for farmers. However, fluctuating fuel costs and evolving subsidy programs affect agricultural productivity. Using linear regression techniques, this study analyzes the relationship between fuel subsidy policies and rice production levels. Key variables include fuel price, rice price, and transportation costs. Data from the National Bureau of Statistics (NBS) enables a robust simulation of policy effects. The model’s performance is assessed using R-square, Mean Square Error (MSE), and Root Mean Square Error (RMSE). Results indicate that approximately 59.8% of the variance in rice production can be explained by the independent variables. The findings highlight the critical role of fuel subsidies in shaping agricultural outcomes, particularly in resource constrained farming communities. This study underscores the need for evidence-based policy decisions to balance subsidy allocation with sustainable agricultural growth.

Published: February 2025

The three main types of parasites found throughout the world are helminths, ectoparasites, and protozoa. Nowadays, chemotherapeutic medications and agents are used to treat these parasites; however, abuse of these medications and pesticides has led to the development of drug and pesticide resistance over time. In this case, silver nanoparticles are shown to be a significant advance in the control and treatment of parasitic illnesses. The science of Nano medicine for parasite control has advanced tremendously in the past ten years and promising outcomes have been observed while treating several kinds of parasite diseases with silver nanoparticles. They function in several ways, including as breaking down the parasite membrane, interfering with the creation of proteins, disrupting DNA (deoxyribonucleic acid), and generating free radicals. These substances also work well against intracellular parasites. One hopes that this field of study will shape the direction of contemporary medication development. The function of silver nanoparticles as possible medications for the treatment of parasitic illnesses is outlined in this review.

Teknik pengumpulan data yang digunakan adalah dokumentasi, wawancara, studi kepustakaan. Sumber data yang digunakan data primer yaitu diperoleh melalui wawancara dengan karyawan perusahaan. Data sekunder berupa data biaya aset biologis dari tahun 2006 s.d, 2010 yaitu sejak dibangunnya kebun sampai dengan tanaman menghasilkan. Hasil penelitian menunjukkan bahwa perusahaan belum menerapkan PSAK 16 dan PSAK 69 dalam menghitung aset biologisnya dengan memasukkan unsur pengadaan lahan, pembangunan infrastruktur, alasannya bahwa keberadaan kebun diakui karena adanya lahan dan infrastruktur, namun berdasarkan PSAK 16 dan PSAK 69 penanaman kelapa sawit meliputi tanaman belum menghasilkan (TBM) yaitu sejak pembibitan sampai dengan tanaman tersebut menghasilkan (TM). Dalam Menilai aset biologis perusahaan masih menggunakan biaya historis (historical cost) dan belum menerapkan nilai wajar (fair value), tanpa memperhitungkan kemungkinan kenaikan fluktuasi harga yang sering terjadi. Akibat ketidaksesuaian perhitungan nilai aset biologis terjadi selisih sebesar Rp. 190.957.447.467. Hal ini berarti perusahaan menghitung nilai aset biologis lebih besar dari nilai berdasarkan ketentuan dalam PSAK 16 dan PSAK 69. Selisih perhitungan ini mengakibatkan salah saji dalam laporan keuangan karena nilai aset biologis belum menggambarkan nilai semestinya terjadi.
DINAMIKA WORKING CAPITAL EFFICIENCY DAN FIRM PERFORMANCE PADA PERUSAHAAN MANUFAKTUR DI INDONESIA
Authors: Utami Dinarossi
Published: February 2025

ABSTRACT
The manufacturing sector plays a critical role in Indonesia’s economic development, requiring financial efficiency to navigate challenges such as globalization, competition, and technological advancements. Despite its importance, inefficiencies in working capital management (WCM) persist, leaving gaps in understanding its impact on firm performance, particularly in emerging markets like Indonesia. This study examines the influence of working capital efficiency (WCE), measured through Net Trade Cycle (NTC) and its components, on Tobin's Q (market-based) and Return on Equity (ROE, accounting-based) among 226 Indonesian manufacturing firms over the period 2010–2023 using panel data regression. The results reveal that NTC has no significant impact on Tobin’s Q, while inventory days (INVD) show a significant negative effect, suggesting that inefficient inventory management diminishes market value. For ROE, NTC, INVD, and receivable days (RECD) have significant negative effects, highlighting the adverse impact of prolonged cash conversion cycles on profitability. These findings align with theoretical expectations that shorter working capital cycles enhance profitability by reducing financial costs and improving cash flow. The implications underscore the need for targeted WCM strategies to optimize liquidity and profitability, contributing to a more competitive manufacturing sector in Indonesia. Future research should explore external moderating factors such as macroeconomic conditions and industry dynamics to provide a comprehensive understanding of WCE’s influence on firm performance.
Keywords: Working capital efficiency, Firm performance.

REVISÃO SISTEMÁTICA: AS TERAPIAS BIOLÓGICAS SÃO MAIS EFICAZES DO QUE TERAPIAS NÃO BIOLÓGICAS NO TRATAMENTO DE PACIENTES COM ARTRITE REUMATOIDE REFRATÁRIA?
Authors: Barral Débora Sarmento Oliveira , Vieira Hannah Mendes , Nogueira Paloma Barros , Loiola Sofia Lopes Magalhães
Published: February 2025

RESUMO: O estudo teve como objetivo revisar sistematicamente a eficácia e segurança das terapias biológicas em comparação com as não biológicas no manejo da artrite reumatoide (AR) refratária ao metotrexato (MTX). Foi conduzida uma análise abrangente de artigos publicados entre 2010 e 2023 em bases como PubMed e Cochrane Library, abrangendo revisões sistemáticas, meta-análises e ensaios clínicos randomizados que abordassem a eficácia de tratamentos biológicos e não biológicos em pacientes com AR refratária. Os resultados mostraram que as terapias biológicas, como os inibidores de TNF-α e anticorpos monoclonais, foram superiores às não biológicas em taxas de resposta clínica (ACR20, ACR50, ACR70), controle da inflamação e qualidade de vida. Contudo, desafios incluem eventos adversos, como infecções respiratórias e sua limitação de eficácia em casos graves. Concluiu-se que as terapias biológicas devem ser priorizadas para pacientes refratários ao MTX, com monitoramento rigoroso para minimizar riscos. Futuros estudos devem explorar combinações terapêuticas e estratégias personalizadas baseadas nos perfis imunológicos e farmacogenéticos dos pacientes, otimizando os desfechos clínicos para subgrupos multirresistentes.

Towards quantitative reconstruction of past monsoon precipitation based on tetraether membrane lipids in Chinese loess
Authors: Guo Jingjing , Ziegler Martin , Fuchs Louise , Sun Youbin , Peterse Francien
Published: February 2025

Abstract. Variations in the oxygen isotope composition (δ18O) of cave speleothems and numerous proxy records from loess–paleosol sequences have revealed past variations in East Asian monsoon (EAM) intensity. However, challenges persist in reconstructing precipitation changes quantitatively. Here, we use the positive relationship between the degree of cyclization (DC) of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in modern surface soils from the Chinese Loess Plateau (CLP) and mean annual precipitation (MAP) to quantify past monsoon precipitation changes on the CLP. We present a new ∼ 130 000-year-long DC-based MAP record for the Yuanbao section on the western edge of the CLP, which closely tracks the orbital- and millennial-scale variations in available records of both speleothem δ18O and the hydrogen isotope composition of plant waxes (δ2Hwax) from the same section. Combing our new data with existing brGDGT records from other CLP sites reveals a spatial gradient in MAP that is most pronounced during glacials, when the western CLP experiences more arid conditions and receives up to ∼ 250 mm less precipitation than in the southeast, whereas MAP is ∼ 850 mm across the CLP during the Holocene optimum. Furthermore, the DC records show that precipitation amount on the CLP varies at both the precession scale and the obliquity scale, as opposed to the primarily precession-scale variations in speleothem δ18O and δ2Hwax at Yuanbao and the 100 kyr cycle in other loess proxies, such as magnetic susceptibility, which rather indicates the relative intensity of the EAM. At the precession scale, the DC record is in phase with δ2Hwax from the same section and the speleothem δ18O record, which supports the hypothesis that monsoon precipitation is driven by Northern Hemisphere summer insolation.
The importance of stratocumulus clouds for projected warming patterns and circulation changes
Authors: Breul Philipp , Ceppi Paulo , Nowack Peer
Published: February 2025

Abstract. Stratocumulus clouds are thought to exert a strong positive radiative feedback on climate change, but recent analyses suggest this feedback is widely under-represented in global climate models. To assess the broader implications of this model error for the modeled climate change responses, we investigate the impact of Pacific stratocumulus cloud feedback on projected warming patterns, equilibrium climate sensitivity and the tropical atmospheric circulation under increased CO2 concentrations. Using the Community Earth System Model with modifications to enhance low cloud cover sensitivity to sea surface temperature (SST) anomalies in Pacific stratocumulus regions, we find increased tropical SST variability and persistence, a higher equilibrium climate sensitivity, an enhanced east–west warming contrast across the tropical Pacific, and a stronger slow-down of the Walker circulation under 4×CO2 conditions. Our findings are supported by inter-model relationships across CMIP6 4×CO2 simulations. These results underscore the importance of accurately representing cloud feedback in climate models to predict future climate change impacts not only globally, but also on a regional scale, such as warming patterns or circulation change.
Amending the algorithm of aerosol–radiation interactions in WRF-Chem (v4.4)
Authors: Feng Jiawang , Zhao Chun , Du Qiuyan , Yang Zining , Jin Chen
Published: February 2025

Abstract. WRF-Chem (Weather Research and Forecasting model coupled with Chemistry) is widely used to assess regional aerosol radiative feedback. However, in the current version, aerosol optical properties are only calculated in four shortwave bands, while only two of them are used to interpolate optical properties towards the 14 shortwave bands used in the Rapid Radiative Transfer Model for Global Climate Models (RRTMG) scheme. In this study, we use a “Resolved” algorithm to estimate aerosol radiative feedback in WRF-Chem, in which aerosol optical properties are calculated in all 14 shortwave bands. The impacts of changing this calculation algorithm are then evaluated. The simulation results of aerosol optical properties are quite different using the new Resolved algorithm, especially for dust aerosols. The alteration of aerosol optical properties results in considerably different aerosol radiative effects: the dust radiative forcing in the atmosphere simulated by the Resolved algorithm is about 2 times larger than the original “Interpolated” algorithm. The dust radiative forcing at the top of the atmosphere (TOA) simulated by the Interpolated algorithm is negative in the Sahara region, while the Resolved algorithm simulates positive forcing at TOA and can exceed 10 W m−2 in the Sahara, which is more consistent with previous studies. The modification also leads to changes in meteorological fields due to alterations in radiative feedback effects of aerosols. The near-surface temperature is changed due to the difference in the radiation budget at the bottom of the atmosphere (BOT) and the heating effects of aerosols at the surface. Furthermore, the amendment of the algorithm partially corrects the wind field and temperature simulation bias compared to the reanalysis data. The difference in planet boundary layer height can reach up to ∼100 m in China and ∼200 m in the Sahara, which also results in a greater surface haze. The results show that correcting the estimation algorithm of aerosol radiative effects is necessary in WRF-Chem.

Published: February 2025

Dalam penelitian ini, digunakan data pergerakan pesawat udara dari Bandar Udara Internasional Husein Sastranegara Bandung. Sehingga dapat di rencanakan tebal perkerasan lentur untuk overlay turn pad. Perencanaan tebal perkerasan menggunakan metode perhitungan dari software FAARFIELD dan dianalisan ACN-PCN menggunakan software COMFAA. Kesimpulannya kondisi turn pad saat ini memiliki elevasi yang berbeda dengan badan runway, karena pada saat pekerjaan overlay runway yang pada tahun 2017 tidak termasuk dengan overlay turn pad sehingga memiliki ketinggian yang berbeda, maka harus dilakukannya overlay pada turn pad. Hasil dari perhitungan tebal perkerasan overlay turn pad pada runway 29 dengan tebal surface course (P-401/P-403 HMA Overlay) 5,8 cm, dan pada turn pad runway 11 dengan tebal surface course (P-401/P-403 HMA Overlay) 5,1cm. Didapatkan nilai PCN (Pavement Classification Number) = 57 F/C/X/T pada turn pad runway 29 dan 103 F/C/X/T pada turn pad runway 11. Didapat nilai ACN (Aircraft Classification Number) pada pesawat B 737-800 dalam metode FAARFIELD yaitu 50. Sehingga dapat diketahui bahwa perencanaan overlay turn pad dari hasil perhitungan dengan metode FAARFIELD mampu bertahan untuk jangka waktu yang lama serta mampu untuk melayani operasi B 737-800 dengan beban maksimal secara optimal karena PCN lebih besar dari ACN.

Penelitian ini mengkaji perlindungan hukum bagi penumpang yang mengalami gangguan kesehatan mendadak selama penerbangan, baik dari perspektif hukum nasional maupun internasional. Meskipun terdapat regulasi yang memadai seperti Undang-Undang Nomor 1 Tahun 2009 tentang Penerbangan dan berbagai Peraturan Menteri Perhubungan, serta konvensi internasional seperti Konvensi Warsawa 1929 dan Konvensi Montreal 1999, implementasi dari regulasi tersebut masih memiliki celah yang dapat menghambat efektivitas perlindungan hukum. Penelitian ini mengidentifikasi beberapa masalah utama seperti kurangnya pengawasan dan penegakan hukum, ketidakjelasan standar layanan medis, dan kurangnya pelatihan awak pesawat dalam menangani situasi medis darurat. Dengan menganalisis celah-celah ini, penelitian ini memberikan rekomendasi untuk memperbaiki implementasi regulasi, meningkatkan kejelasan standar layanan medis, dan memperluas pelatihan untuk awak pesawat. Dengan demikian, penelitian ini bertujuan untuk meningkatkan tanggung jawab maskapai penerbangan dalam situasi darurat medis di udara, serta menciptakan pengalaman perjalanan udara yang lebih aman dan nyaman bagi semua penumpang.

Published: February 2025

A história do Brasil é relativamente recente, mas recheada de diversas peculiaridades acerca da distribuição de terras. Por sermos um país colonizado, não tivemos a oportunidade de experimentar avanços e rupturas sensíveis cujo modelo europeu importado atravessou ao longo do tempo. Não obstante, o incentivo, na época do Primeiro Império, ao latifúndio determina, até a presente data, na questão agrária, notadamente no que tange à concentração fundiária, ainda que estes latifúndios, posteriormente, tenham sido desincentivados pelas legislações supervenientes. A Lei de Terras de 1850, de maneira muito emblemática, autorizou a financeirização da terra, de maneira que, anos mais tarde, a reprodução do capital trouxe impactos sensíveis à cultura jurídica nacional. Como exemplo, foram as diversas ideias impostas pelas legislações brasileiras quanto à reforma agrária e regularização fundiária. Note-se que, ao longo da exposição, as diretrizes estabelecidas no início do Brasil Colônia impactaram sensivelmente na atual necessidade de reprimarização da economia, ensejando em forte aparato jurídico-burocrático na regulação do setor, de maneira que a rica evolução legislativa do Direito Agrário está imbricada em aspectos econômicos fundamentais na realidade atual.
