Modernization of Nigeria’s Mining Industry: The Case for Participation and Sustainable Development of Local Communities
Authors: Ezeudu Martin-Joe 
Published: October 2024

Abstract
To retract from its overdependence on crude oil fortunes and be a participant in the green energy economy, Nigeria has recently begun to revive and modernize its mining industry. The modernization is driven by the Nigerian Minerals and Mining Act, 2007 (NMMA) and Regulations promulgated thereunder. This paper examines whether and to what extent the NMMA and the Regulations provide sufficient legal architecture for local communities to meaningfully participate in mineral development decisions and processes in ways that advance the course of their sustainable development. It acknowledges that participation or meaningful consultation with local communities in regard to decisions or activities pertaining to resource development is a modern strategy for ensuring that local communities obtain the benefits of sustainable development and measures the compliance of the NMMA and its Regulations against the standard tools developed under international law. It attributes the human and environmental sustainability crisis in the Niger Delta region to the failure of the Nigerian government to involve the oil host communities early on in the oil development and governance scheme and warns that Nigeria should not repeat the same error as it embarks on modernizing the solid mineral industry.

The role of auto-HSCT in extranodal natural killer/T cell lymphoma
Authors: Peng Yin-yin , Wang Xin , Liu Lin 
Published: October 2024

Abstract

Objectives
Autologous hematopoietic stem cell transplantation (auto-HSCT) is considered optional consolidation therapy especially for relapsed/refractory extranodal NK/T-cell lymphoma (ENKL), but its applications to newly diagnosed advanced-stage ENKL is currently limited.

Methods
We collected 51 cases of newly diagnosed advanced-stage ENKL patients, including 26 with auto-HSCT and 25 with chemotherapy rather than HSCT, from our hospital between 2014/01 and 2023/12. We summarized the patients’ characteristics, conducted survival analysis of the 51 cases, and analyzed the potential benefits of auto-HSCT to ENKL patients.

Results
It shows that after a median follow-up time of 39 months, the estimated 5-year overall survival (OS) of the 51 newly diagnosed advanced-stage ENKL patients is 73.4%, and their estimated 5-year progression-free survival (PFS) is 73.4%. For patients receiving auto-HSCT, the 5-year OS (91.7%) and PFS (91.0%) are significantly different from those of patients receiving chemotherapy without HSCT (OS 53.3%, PFS 54.5%) (p < 0.05). Univariate and multivariate analysis results suggest that only the l-asparaginase usage in chemotherapy showed significant impact on the OS, and none of concerned factors showed significant impact on the PFS.

Conclusions
Auto-HSCT is indeed an option to newly diagnosed advanced-stage ENKL, but further studies are still required for more strict disease management.
Characterization of Historical and Modern Leathers Using FTIR, XRD, SEM-EDX, and Thermal Techniques
Authors: Singh Sarvesh , Singh Manager Rajdeo 
Published: October 2024

Abstract
A comprehensive study was conducted on four aged leather pieces of British origin that were utilized in book binding, dating back to the period between 1832 and 1860. The objective of this study was to characterize the thermal, structural, and deterioration properties of these historical leather fragments. Additionally, this study included two newly acquired leather samples of Indian provenance, proposed as potential replacements for this historical leather. The investigative process employed Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDX). Through the FTIR analysis, distinct spectral shifts were identified in the amide A band, indicating a disruption of hydrogen bonding within the aged leather. XRD diffractograms revealed the presence of amorphous phases in the aged leather specimens, signifying the deterioration of their triple helical structure. Notably, DSC analysis provided insight into the denaturation of the collagen-tannin matrix inherent to the historical leather, underlining the transformative effects of time on this intricate material composition. Under SEM analysis, cracks, fibre deterioration, and a general weakening in structural integrity were observed in the aged leather fragments. The EDX data identified one of the new leather samples as chrome-tanned, while the remaining samples exhibited characteristics consistent with vegetable-tanned leather.
Job Insecurity, Employability and Financial Threat during COVID-19
Authors: Greenglass Esther , Fiksenbaum Lisa 
Published: October 2024

COVID-19 has resulted not only in widespread illness and death, it has also upended most spheres of social life including the economic/financial one in that it has had large impacts on local economies, resulting in widespread job loss, job insecurity and loss of income. Employability, a psychological construct, refers to the belief that one can get a (another) job in the event of job loss, and financial threat refers to feelings of threat and anxiety associated with one’s finances. During the pandemic, many people experienced job loss due mainly to business closures. The present study examined the relationship between employability, job insecurity due to COVID-19, and financial threat in a Canadian (n= 487) and U.S. (n=481) sample of adults recruited on MTurk early on in the pandemic (April 2020). Participants in the Canadian sample, compared to their American counterparts, were less likely to be employed full-time, 37% vs. 67%, respectively, were more likely to be unemployed, 40% vs. 13%, respectively, and had lower self-reported socio-economic status. A theoretical model was put forward in which employability was associated with less job insecurity and this was related to less financial threat. Results revealed that financial self-efficacy was associated with greater employability, less job insecurity and less financial threat in both samples. Further, feelings that one had enough income to “get by” since the advent of COVID-19, were positively related to employability in both samples, but in the Canadian sample only, these feelings were also related to less job insecurity and less financial threat. Implications of the study’s results are discussed within the economic climate resulting from the pandemic.
Impact of Lactobacillus rhamnosus GG fermentation on shelf life of Volvariella volvacea paste
Authors: Alam H. , Kaur J. , Sharma S. 
Published: October 2024

AbstractPaste formulations of Volvariella volvacea (VV) were developed for its shelf-life enhancement. Egg stage fruiting bodies of mushrooms were used for preparation of salted, spiced, and their fermented pastes. Fermented paste formulations were developed using inoculation with Lactobacillus rhamnosus GG at 0.5% (w/w) and incubation for 2 days at 35 ± 2 °C. The unfermented VV paste was preserved with sodium benzoate of 0.065%, while fermented formulations were kept devoid of any chemical preservative. All formulations were packed in glass jars and retort bags, and thereafter treated in boiling water bath for one hour. The spiced, fermented VV paste scored highest in sensory evaluation and maximum crude protein and moisture contents, while lowest in contents of ash, fat, crude fibre, and carbohydrates. The fermented (salted and spiced) VV pastes showed variation in pH at 4 °C. Shelf life of 56 days was observed for fermented VV paste stored in glass jars under refrigerated conditions. The antioxidant analysis revealed that DPPH radical scavenging activity of fermented paste formulations increased significantly up to 21 days followed by gradual decrease until the 56th day, while total phenolic content of all paste formulations decreased with storage time. Hence, fermented spiced paste showed enhanced nutritive and antioxidative potential and shelf life up to 56 days.

Repairing Dehiscence Defects at Implant Sites using β-Tricalcium Phosphate/Calcium Sulfate versus Xenograft Combined With Membrane: A Randomized Clinical Trial
Authors: Pongsettakul Aksornsan , Leepong Narit , Suttapreyasri Srisurang 
Published: October 2024

ABSTRACT
Guided bone regeneration (GBR) typically involves bone grafts and a membrane to enhance bone formation. Beta-tricalcium phosphate calcium sulfate (β-TCP/CS) is a novel material with self-hardening and tissue growth inhibition properties and can potentially replace the need for a membrane. This study compares β-TricalciumPhosphate/CalciumSulfate with deproteinized bovine bone mineral and a collagen membrane (DBBM/CM) to repair bone defects at implant sites over six months. Sixteen implant defects were divided into β-TCP/CS (n = 8) and DBBM/CM (n = 8). The results showed no significant differences in vertical and horizontal defect fill in millimeters between β-TCP/CS (2.87±1.25 and 2.37±1.06 mm., respectively) and DBBM/CM (3.5±0.92 and 2.87±1.12 mm. , respectively). Buccal bone thickness (BT) alterations at the implant platform levels (BT0) were similar for both materials. However, β-TCP/CS exhibited greater bone alteration at the 2-mm level (BT2: −1.85 mm vs. −0.47 mm) and 4-mm level (BT4: −1.79 mm vs. 0.12 mm) apical to the implant platform compared to DBBM/CM. When assessing volume alteration, β-TCP/CS showed a significantly greater reduction at the platform to the 2 mm level (−61.98% vs. −23.76%) than DBBM/CM. In conclusion, β-TCP/CS demonstrated promise for treating buccal bone defects around implants but exhibited higher graft reduction. This suggests that while β-TricalciumPhosphate/CalciumSulfate may offer clinical benefits, its potential for greater graft reduction should be considered. Further research and evaluation are warranted to fully understand the long-term implications of using β-TCP/CS in guided bone regeneration procedures.

Енергетичні установки, що реалізують органічний цикл Ренкіна (ORC), дають змогу впроваджувати в промисловість перспективні технології, що орієнтовані на підвищення ефективності використання низькопотенційних джерел енергії та теплових відходів. Як робочі для таких енергетичних об'єктів найчастіше використовують речовини, які мають порівняно високу температуру кипіння, високі екологічні властивості. Нині як найбільш перспективне робоче тіло для установок, що реалізують цикл Ренкіна, широко використовують холодоагент R245fa. Теплофізичні властивості цього робочого тіла добре вивчені. У статті наведено інформацію про дослідження локальних коефіцієнтів тепловіддачі для рідкої, парової фаз і середніх за перерізом труби коефіцієнтів тепловіддачі під час кипінні R245fa в генераторі пари, яка в літературі практично відсутня. Дослідження коефіцієнтів тепловіддачі виконано нестаціонарним методом за змінної масової витрати робочого тіла. Робочу ділянку виготовлено зі сталевої трубки з внутрішнім діаметром 5 мм, товщиною стінки 0,1 мм. Ефективна довжина робочої ділянки становила 1800 мм. Експериментальна ділянка була поділена на десять секцій, на кожній з яких проводилося вимірювання середньої температури стінки. На секціях котрі знаходяться на вході та виході експериментального також розташовані диференційні термопари які вимірювали різницю температури між робочим тілом та стінкою труби Масові потоки робочого тіла, ступінь сухості парів і теплові потоки перебували в діапазонах 1…12 кг/(м2⋅с), 0,01…0,9 і 0,4…0,6 кВт/м2, відповідно. Витрата визначалася ваговим методом і невизначеність отриманих значень не перевищувала 0,5 г. Локальні для рідини і пари коефіцієнти тепловіддачі та середній на секції робочої ділянки коефіцієнт тепловіддачі визначено для розшарованого режиму кипіння. Досліджено вплив ступеня сухості пари R245fa на значення коефіцієнтів тепловіддачі. Запропоновано методику визначення середньої температури стінки труби робочої ділянки. Показано, що значення середнього коефіцієнта тепловіддачі при збільшенні ступеня сухості пари зменшується. Середній коефіцієнт тепловіддачі змінює своє значення від величини локального коефіцієнта тепловіддачі для рідкої фази до величини локального коефіцієнта тепловіддачі для парової фази

Este proyecto aborda la prevalencia de los trastornos osteo-musculares y los factores asociados en los mineros. El objetivo principal es comprender la relación entre las características personales y laborales de los mineros y los trastornos osteo-musculares, con el fin de desarrollar medidas de prevención y tratamiento adecuados para proteger su salud y bienestar. La metodología consistió en encuesta de perfil socio demográfico y cuestionario Nórdico, realizado a 15 trabajadores de la mina. Se recopilaron datos demográficos, síntomas osteo-musculares y se evaluaron factores de riesgo como el sobrepeso y tareas laborales específicas. Los análisis revelaron que la mayoría de los mineros eran adultos jóvenes, lo que puede influir en la forma como manipulan cargas y se exponen a trastornos osteo-musculares. Además, la mayoría de los trabajadores tenían sobrepeso y baja escolaridad, lo que aumenta el riesgo de DME. Se destaca la importancia de considerar las tareas que realizan los mineros, como manipulación de cargas y la postura para comprender mejor los DME.
En cuanto a resultados, se encontró una alta prevalencia de DME en los mineros encuestados. Las zonas más afectadas fueron las muñecas, cuello, rodillas y espalda. Estos hallazgos respaldan la relación entre el tipo de trabajo realizado y los trastornos osteo-musculares debido a cargas pesadas, movimientos repetitivos y malas posturas. En resumen, este proyecto destaca la importancia de considerar las características personales y laborales de los mineros para desarrollar estrategias de prevención efectivas. La alta prevalencia de DME encontrada subraya la necesidad de tomar medidas para proteger su salud y bienestar.
A Stochastic Model for Induced Seismicity at the Geothermal Systems: A Case of the Geysers
Authors: Shcherbakov Robert 
Published: October 2024

Abstract
Induced seismicity has emerged as a source of a significant earthquake hazard associated with recent development of unconventional energy resources. Therefore, it is imperative to develop stochastic models that can accurately describe the observed seismicity rate and forecast its evolution. In this study, a mechanism suggested by linear response theory is incorporated into a stochastic earthquake model to account for changes in the seismicity rate. It is derived that the induced rate can be modeled as a convolution of the forcing, related to fluid injection operations, and a specific response kernel. The model is incorporated into a Bayesian framework to compute the probabilities for the occurrence of the largest expected events during future time intervals. The applicability of the model is illustrated by analyzing the injection and seismicity data at the Geysers geothermal field in California. The suggested approach provides further insight into the probabilistic assessment of earthquake hazard associated with fluid injection operations. It also can be used for probing the rheological properties of the subsurface by analyzing the inherent characteristic timescales associated with the subsurface response to external forcing.

Authors: Neroev V. V. , Ovechkin N. I. 
Published: October 2024

Purpose. Analysis of modern aspects of cataract surgery from the standpoint of the medical and social model of health.Methods. The analysis of literary data was performed in the RSCI and PubMed databases using the following keywords: “Medical model of health”, “Medical and social model of health”, “Phacoemulsification of cataracts” (PCE), “Quality of life” (QOL), “Calculation of intraocular lenses” (IOL), “Visually intense work”, “Ophthalmo-ergonomics”. The duration of the main retrospective analysis was 8 years (2017–2023) with citation (if necessary) of individual earlier sources.Results. Based on the analysis, the following main modern aspects of cataract surgery were identified from the standpoint of the medical and social model of health: QOL study; assessment of ophthalmo-ergonomic indicators; medical and psychological aspects (correction of postoperative pain syndrome and dry eye syndrome, neuroadaptation after implantation, primarily trifocal IOLs, patient anxiety level).Conclusion. Currently, the PCE procedure is almost completely optimized from a technical point of view. In this regard, consideration of the PCE effectiveness from the standpoint of the medical and social model of health seems relevant, since the main task of this model is the complete integration of an individual into society. The basic indicator reflecting the clinical effectiveness of PCE from the standpoint of the medical and social model of health is QOL. In this direction, the practical application of the «FEC-22» QOL assessment technique will ensure an increase in the level of clinical diagnostic research in cataract surgery when solving a number of urgent problems — comparative evaluation of IOLs, study of the effectiveness of postoperative rehabilitation methods for patients, selection of the optimal formula for calculating IOLs. In addition, from the standpoint of the medical and social model of health, further improvement of the ophthalmo-ergonomic indicators of the visual system and medical and psychological aspects associated with the patient is advisable. Ultimately, the development of a comprehensive system of measures to improve the clinical and diagnostic effectiveness of phacoemulsification based on the medical and social model of health will improve the level of ophthalmological care and prolong the professional longevity of patients (especially those with visual impairment) with cataracts.
