Authors: Manikandan S. , Raj A. I. , Ponvel Keerthana , Ramanathan Manikandhan , Tangutur Srinisava Prasad
Published: February 2025

Objectives:

One of the main reasons for patients to postpone most of the dental procedures is the fear of dental injections. Conventional injection technique has no control over the rate of flow of the anesthetic solution and the fluid pressure varies depending on manual force used by the practitioner. Recent advancements have led to various other painless injection systems, one of such is the “Local Anesthetic Gun” (Sunshine USA). Hence, we conducted a study to statistically prove if pain perceived is lesser during injection with a local anesthetic (LA) gun compared to that with conventional injection using cartridge while administering various infiltrations and nerve blocks.

Materials and Methods:

Patients undergoing bilateral therapeutic extraction of premolar teeth were taken up for the study. The teeth to be extracted from the left side (second and third quadrants) were anesthetized by conventional injection technique using cartridges and the teeth to be extracted from the right side (first and fourth quadrants) were anesthetized using LA gun. The procedure is conducted in two separate appointments, with a minimum gap of seven days between each. Patients are asked to rate the pain during injection using a Visual Analog Scale and Verbal Response Scale.

Results:

This study shows that the pain perceived during injection with the anesthetic gun was considerably lesser than perceived with the use of cartridge.

Conclusion:

In our study, it was concluded that the pain perceived during the administration of local anesthesia was significantly lesser with the use of anesthetic gun compared to the conventional cartridge, in patients undergoing therapeutic extraction of premolar teeth, for orthodontic treatment.
Finding lower bounds on the growth and entropy of subshifts over countable groups
Authors: Rosenfeld Matthieu
Published: February 2025

We provide a lower bound on the growth of a subshift based on a simple condition on the set of forbidden patterns defining that subshift. Aubrun, Barbieri, and Thomassé showed a similar result based on the Lovász local lemma for subshifts over any countable group, and Bernshteyn extended their approach to deduce some lower bound on the exponential growth of the subshift. Our result has a simpler proof, is easier to use for applications, and provides better bounds on the applications from their articles (although it is not clear that our result is strictly stronger in general). In the particular case of subshifts over

\mathbb{Z}

, Miller gave a similar but weaker condition that implied the non-emptiness of the associated shift. Pavlov used the same approach to provide a condition that implied exponential growth. We provide a version of our result for this particular setting, and it is provably strictly stronger than the result of Pavlov and the result of Miller. In practice, it leads to considerable improvement in the applications. We also apply our two results to a few different problems including strongly aperiodic subshifts, nonrepetitive subshifts, and Kolmogorov complexity of subshifts.

E-Government Development and its Role in Enhancing Government Effectiveness and Public Sector Governance
Authors: Bhatti Muhammad Azhar , Hussain Altaf , Ahmad Tusawar Iftikhar , Nawaz Muhammad Atif
Published: February 2025

The digital transformation within public administration is fundamental to improving government effectiveness levels. The study employs CS-ARDL analysis to evaluate the relationship between e-government development and governance indicators (control of corruption, e-government, rule of law, regulatory quality, and voice and accountability) concerning Government Effectiveness in the short and long term. According to the study findings, control of corruption, regulatory quality, and citizen participation demonstrate short-run effects on Government Effectiveness. The combination of quick expansions in the rule of law regulations and previous government efficiency creates obstacles to present-day administrative success, indicating potential administrative flexibility problems. Sustainable improvements in government effectiveness emerge from robust control of corruption combined with high regulatory quality, active voice, and accountability during the long-run analysis. Combining e-government platforms with strict regulations shows inverse relationships to sustainable effectiveness because proper institutional backing and supplementary reform measures are essential for digital tools to produce intended benefits. The findings demonstrate the need for government officials to unite digital initiatives with extensive institutional capacity development because this combination enables e-government programs to create better public service provision and governance outcomes.
A Simplified Design and Modeling of Boost Converter for Photovoltaic System
Authors: Nikunj Patel  , Dr. Rakeshkumar A. Patel
Published: February 2025

The photovoltaic standalone system is becoming increasingly important, particularly for rural applications such as PV water pumping, solar lighting, and battery charging. Due to environmental concerns and the depletion of fossil fuels, there is a growing shift toward renewable energy sources. This paper presents the design of a basic boost converter circuit in MATLAB/Simulink with a constant DC source voltage. Additionally, a comparative analysis is conducted between a converter directly connected to a PV system and one integrated with an MPPT tracking technique. The Perturb and Observe (P&O) algorithm is implemented to generate the required duty pulse, ensuring the system operates at the maximum power point. When the boost converter is connected to the PV system without MPPT, it operates at a point other than the maximum power point, leading to reduced output voltage. However, with MPPT, the proposed system demonstrates improved performance.

Measurement of mean platelet volume in the diagnosis of acute ischemic stroke and transient ischemic attack
Authors: Boğa Erkan
Published: February 2025

Abstract
Aims: The primary aim of this study is to investigate the potential role of mean platelet volume (MPV) in the diagnostic and prognostic evaluation of acute ischemic stroke (AIS) and transient ischemic attack (TIA), focusing on its clinical significance and role in diagnostic processes. This study aims to evaluate the clinical significance of MPV in patients with AIS and TIA and its role in diagnostic processes.
Methods: This retrospective study was conducted between June 15 and December 15, 2014, at the Emergency Medicine Department of Haydarpaşa Numune Training and Research Hospital. The study included 300 patients diagnosed with AIS or TIA and 100 healthy individuals matched for demographic characteristics as the control group. Participants were evaluated based on vascular risk factors such as hypertension, diabetes, and hyperlipidemia, and AIS subgroups were analyzed according to the TOAST classification. MPV and platelet counts, along with biochemical parameters, were measured, and statistical analyses were performed utilizing SPSS software.
Results: MPV values in the case group were significantly higher compared to the control group (p<0.001). No significant differences were observed in platelet counts between the two groups (p>0.05). MPV demonstrated no significant associations with hypertension, hyperlipidemia, or other vascular risk factors; however, patients with a history of TIA exhibited higher MPV levels compared to those without, although the difference was not statistically significant. A weak but statistically significant negative correlation was identified between MPV and platelet counts (r=-0.20, p<0.05).
Conclusion: MPV demonstrates potential as a significant biomarker in the diagnostic and prognostic processes of AIS and TIA. Nevertheless, the inconsistencies observed in the literature regarding the relationship between MPV and risk factors necessitate more extensive, prospective, and standardized studies to elucidate its clinical utility. The evidence suggests that MPV may contribute to enhancing diagnostic accuracy in clinical practice.

Published: February 2025

Aims: This study aims to evaluate the clinical outcomes of topical epidermal growth factor (EGF) in the treatment of diabetic foot ulcers (DFUs) in outpatient settings. It also seeks to provide guidance on the use of topical EGF, which is eligible for reimbursement for treating DFUs in our country.
Methods: A retrospective analysis involved 55 patients with DFUs who received topical EGF treatment. Patients received training on EGF application and were monitored for healing outcomes. Data were collected from medical records, including demographic information, wound characteristics, and laboratory results. Statistical analysis was performed using IBM SPSS version 25, employing chi-square, Pearson's correlation, and ANOVA tests to evaluate healing rates and associated factors.
Results: The study found that 70.9% of patients achieved complete wound closure within an average of 15.44 weeks. Healing rates were significantly higher for non-plantar wounds (83.8%) compared to plantar wounds (44.4%). Factors such as age, body weight, and body-mass index (BMI) were identified as influencing healing outcomes, with higher weights and BMI correlating with lower healing rates. Mild skin irritation was the only adverse effect reported.
Conclusion: Topical EGF demonstrates promising potential for enhancing the healing of DFUs in outpatient settings, achieving a healing rate comparable to specialized diabetic foot centers. The findings underscore the importance of considering patient specific factors, such as obesity and adherence to treatment recommendations, to optimize healing outcomes. Further research with larger, multi-center studies is necessary to validate these results and improve access to effective treatments for patients with DFUs.

Authors: Mangi Pato , Troon Benedict , Ombok Maurice , Kemboi Gladys
Published: February 2025

Purpose: Aggregate private investment is key in stimulating economic growth and development of a country such as Kenya. However, the sector seems to be influenced by changes in macroeconomic variables. Therefore, the study aimed at determining the effect of change in macroeconomic variables on aggregate private investment growth in Kenya. It focused on the effect of changes in interest, inflation and exchange rates on aggregate private investment growth in Kenya as the key objectives of the study.
Methodology: The study adopted the quantitative causal research design.  Secondary data obtained from the World Bank was used, with a time scope of between 1972 and 2023. Data was analyzed through exploratory and inferential analyses via R software. Cointegration analysis was carried out through the Johansen test and both the Maximum Eigenvalue and Trace tests indicated the absence of cointegration relationships since the test statistic values were less than the critical values at ∝ = 0.05. Thus, ARDL estimation technique was adopted.
Findings: The study’s findings indicated that change in interest rate had a statistically significant negative effect on aggregate private investment growth in Kenya (P-value < 0.05). Furthermore, the study revealed that such effect wasn’t instant but was translated after three years. The study further found that change in inflation rate had a statistically significant positive effect on Kenya’s aggregate private investment growth (P-value < 0.05). Likewise, such effect was felt on aggregate private investment after eight years. Finally, the study showed that change in exchange rate did not have any significant effect on aggregate private investment growth in Kenya (P-value > 0.05).
Unique Contribution to Theory, Practice and Policy: The study recommends the need to manage the changes in macroeconomic variables including inflation and interest rates within their target range as prescribed by the “monetary policy” so as to ensure macroeconomic stability and boost aggregate private investment growth in Kenya.

Plant Growth Regulators Application to Enhance Flowering and Fruit Production in Gac (Momordica cochinchinensis)
Authors: Hamidon Azimah , Mohd Shah Ramisah , Mohd Razali Razifah , Lob Suhaizan , Abdul Aziz Fatma Azwani
Published: February 2025

Gac fruit (Momordica cochinchinensis) has garnered substantial interest due to its potential as a rich source of lycopene and β-carotene, prompting higher demand for large-scale production. However, the development of its female flowers is hindered by the dioecious nature of the gac plant, demanding manual pollination to enhance fruit yield. In addition, the female flower of the gac plant starts late, depending on environmental variables such as temperature, moisture, and photoperiod. Accelerating flowering onset and augmenting pollination could substantially amplify gac fruit production, provided a comprehensive comprehension of exogenous plant growth regulators is attained. Accordingly, the current study investigates the role of plant growth regulators at various concentrations in developing female flowers and fruit production in gac plants. A field planting experiment was conducted using a five-replication factorial randomized complete block design (RCBD). The combination treatments comprised two factors of interest, which were four different types of plant growth regulators (indole-3-acetic acid [IAA], gibberellic acid [GA], benzyl adenine [BA], and maleic hydrazide [MH]) at four different concentration rates (0, 40, 80, and 120 ppm). Notably, Gac plants treated with MH at concentrations of 40 and 80 ppm exhibited significant performance in node and pistillate count, ovary diameter, early onset of first flower anthesis, and fruit yield. These findings underscore the potential of MH as a potent growth regulator for enhancing gac fruit production. Nonetheless, more research on agronomic practices, control environment modifications, and postharvest handling is required for the profitable production of the gac fruit.

Soil infertility is a significant challenge in achieving sustainable agricultural practices. In this regard, the chemical fertilizer usage is not an environmentally friendly solution. Organic amendment and bacterial inoculation can positively restore soil quality, enhancing biogeochemical nutrient cycles. In this study, we assessed the effect of adding plant growth-promoting bacteria (PGPB) alongside organic amendments on the physicochemical parameters of sandy-loam soils. Over a 90-day pot experiment, we measured organic matter accumulation, physicochemical, chemical variation trends and changes in microbial community assemblages. Working on the joint application could have a synergistic effect; different agro wastes spent such as mushroom substrate (SMS), empty fruit bunch (EFB) of palm oil and pineapple leaf (PL) residue was amended with Paenibacillus polymyxa ATCC 825 and effective microorganism. Significant changes in soil properties (physicochemical and microbial community) due to the application of P. polymyxa and SMS-amended material were observed after incubation. On average, an increase in water holding capacity, soil pH and mineral content availability was significantly higher than other amended materials. Compared to others, the organic amendment significantly increased sandy-soil aggregation content by 44%. In addition, increased taxonomic diversity in phyla composition was observed with an abundance of Proteobacteria (33%), Firmicutes (18%), Actinobacteria (14%), Bacteriodata (12%), and Verrucomicrobia (6%). The findings indicate that the addition of SMS amendment with bacterial inoculation is beneficial for problematic soil recovery. The incorporation of bacterial inoculation, specifically P. polymyxa ATCC 825, following organic amendment, seems to have a greater positive effect on the soil characteristics.

Published: February 2025

Pigeon pea (Cajanus cajan) seeds are widely consumed as a staple food in numerous countries, with leaves recognized for various medicinal values, particularly in flavonoid production. Therefore, this study aimed to investigate leaf flavonoid production in pigeon peas through recurrent harvesting at different heights and the application of cow manure rate. The experiment was carried out in a Split Plot Design, with the main plot consisting of three levels of cow manure at 0, 15, and 30 tons/ha, while the subplots comprised no pruning, 100 and 125 cm above the ground. The findings indicated no observed interaction between cow manure and pruning concerning the variables studied. Recurrent harvesting with 30 tons of cow manure/ha produced a total leaf flavonoid of 2228.3 mg quercetin equivalent (QUE)/100 g leaf dry weight. It showed that 30 tons of cow manure/ha needed to be reapplied for three consecutive harvests since the value declined from the second to the third harvesting. Pruning at different heights above ground produced no significant differences in total leaf flavonoid per plant, with a range of 841.10–1,539.00 mg QUE/100 g leaf dry weight.

Dalam Kardiologi modern, inhibitor sodium-glucose cotransporter 2 (SGLT2) merupakan komponen penting dari algoritma penanganan gagal jantung (HF) dengan efek utama mencegah reabsorpsi glukosa dan memperlancar ekskresi urin. Tujuan penelitian ini adalah mengkaji secara sistematis randomized controlled trials (RCT) yang mengkaji efektivitas terapi inhibitor SGLT2, khususnya Dapagliflozin dan Empagliflozin pada pasien reduced fraction ejection heart failure (HFrEF). Pencarian data menggunakan kata kunci heart failure , SGLT2 inhibitors, dan reduced ejection fraction pada 3 (tiga) database jurnal antara lain Pubmed/MEDLINE, JSTOR, dan Cochrane/Wiley online library dengan batasan penelitian 2 (dua) tahun terakhir. Dari total 500 artikel, setelah dilakukan ekstraksi dan analisis data, diperoleh 13 artikel yang sesuai dengan kriteria inklusi (full text, original text, pasien HFrEF dengan inhibitor SGLT2, dan Placebo, RCT). Inhibitor SGLT2 (Dapagliflozin dan Empagliflozin) memiliki efek mengurangi kematian kardiovaskular atau memperburuk gagal jantung sehingga secara signifikan meningkatkan kualitas hidup pada pasien gagal jantung (HFrEF). Dapagliflozin mengurangi risiko kematian kardiovaskular dan memburuknya gagal jantung secara serupa pada pasien kulit hitam atau putih, seperti pada pasien dengan fibrilasi atrium (AF), meningkatkan parameter ekokardiografi, kapasitas fungsional maksimal paru-paru dan hemoglobin, dan menurunkan Asam Urat (UA), sementara Empagliflozin mampu mengurangi kematian kardiovaskular, mengurangi rawat inap gagal jantung dan mengurangi volume darah stres (SBV), menurunkan berat badan dan menurunkan laju Filtrasi Glomerulus (GFR), menurunkan Volume Sistolik Akhir Ventrikular Kiri (LVESV), Volume Diastolik Akhir Ventrikular Kiri (LVEDV) dibandingkan dengan peningkatan faktor diferensiasi pertumbuhan -15 (GDF-15) tanpa perubahan pada biomarker inflamasi hsCRP atau plasma hsTNT (penanda cedera miokard), meningkatkan eritropoesis dan menambah penggunaan zat besi dini.

Okul müdürlerinin benimsediği yönetim tarzları ile öğretmenlerin örgütsel adalet algıları arasındaki ilişkinin araştırıldığı bu çalışma ilişkisel tarama modelinde tasarlanmıştır. Araştırmanın evrenini Konya ili Selçuklu, Meram ve Karatay merkez ilçelerinde yer alan resmi ilkokul, ortaokul ve liselerde görev yapan öğretmenler oluşturmaktadır. Araştırmada uygun örnekleme yöntemi ile 458 öğretmenden veri toplanmıştır. Araştırmada veri toplamak için “Algılanan Müdür Yönetim Tarzı Ölçeği”, “Örgütsel Adalet Ölçeği” ve “Kişisel Bilgi Formu” kullanılmıştır. Veriler, betimsel istatistik, t testi, tek yönlü ANOVA ve korelasyon analizi teknikleri kullanılarak analiz edilmiştir. Öğretmenler tarafından algılanan örgütsel adalete ilişkin bulgular incelendiğinde öğretmenler, okul müdürlerinin adil olduğunu düşünmektedir. Öğretmenlerin örgütsel adalet algılamalarında cinsiyet, eğitim düzeyi, yaş, kıdem, branş ve okul türü değişkenlerine göre anlamlı şekilde farklılaştığı tespit edilmiştir. Elde edilen bulgulara göre okul müdürlerinin en çok işbirlikli yönetim tarzını ardından sırasıyla otoriter yönetim tarzı, karşı koyucu yönetim tarzı ve ilgisiz yönetim tarzlarını benimsedikleri tespit edilmiştir. Öğretmenlerin okul müdürü yönetim tarzı algılarının cinsiyet, eğitim düzeyi, kıdem, branş ve okul türü değişkenlerine göre anlamlı bir şekilde farklılaştığı görülmektedir. Algılanan okul müdürü yönetim tarzları ile öğretmenler tarafından algılanan örgütsel adalet arasındaki ilişkiyi belirlemek için yapılan korelasyon analizi sonucunda okul müdürlerinin benimsediği işbirlikli yönetim tarzı ve otoriter yönetim tarzı ile örgütsel adaletin alt boyutları olan dağıtımsal adalet, işlemsel adalet ve etkileşimsel adalet arasında pozitif yönlü ve yüksek düzeyde ilişki olduğu; ilgisiz yönetim tarzı ve karşı koyucu yönetim tarzı ile örgütsel adaletin tüm alt boyutları arasında negatif yönlü ve düşük düzeyde ilişki olduğu saptanmıştır. Bu araştırmadan elde edilen bulgular arasında en dikkat çekici olan otoriter okul müdürlerinin de öğretmenler tarafından yüksek düzeyde adil algılanmasıdır.

A influência da filosofia de Aristóteles na teologia de Tomás de Aquino
Authors: Paiva Adriano Santos , Bastos Deise Regina Badotti
Published: February 2025

A influência da filosofia de Aristóteles na teologia de Tomás de Aquino representou um marco fundamental na relação entre filosofia e teologia durante a Idade Média. Ao adotar elementos do pensamento aristotélico, Tomás de Aquino conseguiu desenvolver uma estrutura filosófica que sustentava e complementava sua teologia cristã. Ele fez uso de conceitos centrais de Aristóteles, como substância, ato e potência, além da teoria das quatro causas, para abordar questões cruciais da fé cristã de forma racional e sistemática. Essa incorporação foi fundamental para Tomás, pois permitiu a criação de uma síntese inovadora entre razão e fé, algo inédito para a época. O pensamento tomista conseguiu, assim, articular uma compreensão profunda sobre a existência de Deus, a criação, a moralidade e a natureza humana, utilizando uma base filosófica sólida. Além disso, o artigo explora como Tomás de Aquino, ao adaptar essas ideias aristotélicas ao contexto cristão, promoveu uma nova forma de pensar que valorizava tanto a revelação divina quanto a capacidade humana de raciocínio. Essa fusão de conceitos filosóficos e teológicos estabeleceu Tomás como um dos maiores pensadores da Igreja, e seu trabalho continua a influenciar o pensamento cristão até os dias atuais.
Estudos da deficiência: principais modelos e concepções
Authors: Gomes Gabrielle Muller , Oliveira Liliane Assumpção
Published: February 2025

Este artigo é resultado das investigações realizadas na disciplina Tópicos especiais em diversidade, diferença e desigualdade social na educação I – Estudos de Deficiência (Disability Studies) e pesquisa acadêmica do Programa de Pós-Graduação em Educação - PPGE, da Universidade Federal do Paraná (UFPR), que envolveu a sistematização dos modelos e concepções teóricas sobre a deficiência. Com base nisso, foi feita a seguinte problemática: quais são os principais modelos e concepções teóricas presentes nos estudos sobre a deficiência ao longo dos anos? Definiu-se, então, como objetivo geral: identificar os principais modelos e as teorias presentes nos estudos sobre a deficiência ao longo dos anos. Como objetivos específicos, estabeleceu-se: 1) descrever os principais acontecimentos históricos; e 2) relacionar os modelos teóricos com o contexto histórico. Para responder à problemática e contribuir para o alargamento das discussões sobre esses modelos, foi utilizado como aporte teórico os estudos de Diniz (2007), Piccolo e Mendes (2022), França (2013) e Lopes, Solvalagem e Busse (2020). Como resultado, pode-se chegar aos modelos teóricos que moldaram a compreensão da deficiência ao longo do tempo, reconhecendo que, no modelo social, o fenômeno é compreendido como opressão social e teve importantes pautas sendo discutidas com a primeira e segunda geração. Além disso, verifica-se que o modelo médico, entendendo a deficiência como consequência do corpo com lesão, ainda persiste atualmente. Por fim, conclui-se que a compreensão dos principais modelos e seus pressupostos são relevantes para orientar futuras discussões, políticas e práticas inclusivas.
