Geology and Gold Exploration in the Nansatsu District, Southern Kyushu, Japan
Authors: Hayashi Toshihiko
Published: August 2024

There are three main gold deposits, Kasuga, Iwato, and Akeshi, in the Nansatsu district of southern Kyushu, Japan (Fig. 1). These three deposits have similar geologic characteristics and are the type deposits for the so-called Nansatsu- style of mineralization (Urashima, 1975), more commonly referred to these days as high-sulfidation epithermal Au mineralization (Hedenquist, 1987). This style of mineralization is believed to be a product of high-temperature acid fluids genetically related to magmatic activity at shallow depths (Matsuhisa et al., 1991; Hedenquist et al., 1994). More than 27 tons (t) of gold have been produced from these three deposits. The ore from these deposits, which is hosted by highly silicified rock, is sold to copper smelters in Japan as flux.

From this point you can see the Hatchobaru geothermal power plant to the southeast (fig. 1 of Taguchi, 2001) and also steam from Kuju-iwo yama. The reinjection site is situated to the north of the power plant, whereas the production wells are distributed to the south. To the east, steaming ground known as the Komatsu-jigoku occurs along the Komasuike fault, which extends to Sujiyu town, making a V-shaped valley. A high-temperature zone (>270°C) trending northwest-southeast beneath the power plant (1,000 m below the surface) corresponds to the position of the Komasuike fault. Otake is located to the north, where you can recognize steam only from the power plant.
Metamorphism, Polydeformation, and Extensive Remobilization of the Balmat Zinc Orebodies, Northwest Adirondacks, New York
Authors: DeLorraine William F.
Published: August 2024

Zinc orebodies of the Balmat-Edwards-Pierrepont Zinc mining district in the northwest Adirondacks of New York State rank as near world-class deposits having nearly 40.8 million metric tonnes (Mt) of past production plus reserves grading 9.4% Zn. Orebodies occur in Mesoproterozoic siliceous dolomitic marble that was metamorphosed and polydeformed during the Grenvillian orogeny about 1.1 Ga. Remobilization of inferred syngenetic massive ore during high-grade metamorphism has been locally extensive depending on the stratigraphic unit from which a particular orebody originated. Two remobilized orebodies, the Loomis and Lower Gleason at No. 3 Mine, show clear linkage to the Upper Gleason, a massive, high-grade parent lens of ore. The extent to which ore was remobilized from the Upper Gleason has only recently been discovered.

External remobilization is over 500 m laterally discordant to stratigraphy and over 2000 m in the down-plunge dimension. Daughter orebodies or remobilized daughter ore zones within orebodies are well documented elsewhere at Balmat. There also exist clearly discordant, externally remobilized, daughter ore-bodies for which the source or parent bed can be inferred but which have not yet been located. The Upper Fowler and Mud Pond orebodies are two such “orphans” whose existence depends upon a third, parent orebody hitherto unsuspected but now predicted to reside in unit 6. The extent to which ore is dissipated to tectonic slides is limited by the presence of thick, bedded anhydrite layers in the section. Tectonic slides die out in anhydrite so that sulfide migration is constrained by the impingement of faults into those strata. In the Fowler orebody, distances of remobilization less than several hundred meters are observed because the structure was encased by flowage of anhydrite very early on in its evolution, effectively sealing off any further sulfide migration. Plastic flow, and to some extent fluid-aided plastic flow, along ductile-brittle synmetamorphic faults or tectonic slides is thought to have been the dominant transport mechanism. There is a clear association between rock type and ore thickness. Ore is thicker where it follows the trends formed by the intersection of competent, silicated units with mineralized fault or tectonic slide surfaces, and thinner where following intersection trends of ductile rocks with fault surfaces. Substantial revisions are made here to the number of ore-forming cycles in the Balmat section from six or more, down to three. Evaporite deposition in the form of anhydrite is tied closely to sulfide deposition so that three “evaporite-ore” events are recognized in the Balmat section corresponding to source horizons in units 6, 11, and 14. Any ore in contact with other units in the Balmat section is “in transit” and may have been remobilized significant distances from its source bed.
Geochemical Constraints on the Origin of the Sterling Hill and Franklin Zinc Deposits, and the Furnace Magnetite Bed, Northwestern New Jersey
Authors: Johnson Craig A.
Published: August 2024

The Purpose of this chapter is to review two aspects of the geochemistry of the Sterling Hill and Franklin zinc-ironmanganese deposits and the Furnace magnetite bed that underlies the Franklin deposit. These are (1) oxidation and sulfidation states determined from heterogeneous phase equilibria, and (2) stable isotopic compositions determined from analyses of carbonate, silicate, oxide, and sulfide minerals. The data place constraints on the genesis of the ores, which is the topic of the final section of the chapter. This review draws heavily from the results of my own dissertation research on Sterling Hill (Johnson, 1990; Johnson et al., 1990a) and from recent and continuing projects (Johnson et al., 1990b, Johnson, 1994, 1996, 1997; Volkert et al., 2000); it also includes the sulfur isotope results obtained by Ault (1957). For a complete review of the geology of the deposits, the reader is referred to the chapter by Metsger (2001), and to Metsger et al. (1958) and Frondel and Baum (1974). A complete catalog of the extensive literature on the deposits is given by Dunn (1995).

The Sterling Hill and Franklin deposits are located in northwestern New Jersey within the Reading Prong-Hudson Highlands terrane, which is a belt of Mesoproterozoic sedimentary and igneous rocks that was regionally metamorphosed during the Grenvillian orogeny at about 1.0 Ga. Although the question has arisen as to whether the zinc and associated metals in these deposits were emplaced before or after the metamorphic event, it is now clear from structural, geochronologic, and phase equilibrium studies
Field Trip Days 1 and 2

The First day of the field trip covers the regional geology of the Vermont copper belt and a visit to the Elizabeth mine, near South Strafford, Vermont (Fig. 1, Stops 13). The second day of the trip is a half-day visit to the Ely mine near West Fairlee, Vermont (Fig. 1, Stops 4 and 5). Several of our stops were included in the 1993 Society of Economic Geologists Guidebook Volume 17 trip titled “Besshi-type Massive Sulfide Deposits of the Vermont Copper Belt” (Slack et al., 1993). The purpose of that trip was to acquire an understanding of the regional stratigraphy, structure, and genesis of the mineral deposits. The purpose of our trip is quite different. This trip will examine the environmental geochemistry and mining history of massive sulfide deposits in the Vermont copper belt.

Massive sulfide deposits are among the most likely types of mineral deposits to develop acid mine drainage because (1) ores are enriched in iron-sulfide minerals which are likely to produce acid upon weathering; (2) iron-sulfide minerals (pyrrhotite and pyrite) are ubiquitous as gangue minerals that end up in flotation tailings and mine waste; (3) copper, lead, zinc and other sulfide minerals are present in ore assemblages, so weathering can release a variety of heavy metals; and (4) host rocks typically are carbonatepoor metasedimentary or metavolcanic rocks that have little or no capacity to neutralize acid.

Streams draining both the Elizabeth mine (Copperas Brook) and the Ely mine (Ely Brook) are impacted by acid mine drainage. In
Airborne Imaging Spectrometer and Field Spectroscopic Studies of Mine Wastes at the Elizabeth Mine, Vermont
Authors: Crowley James K. , Mars John C. , Hammarstrom Jane M.
Published: August 2024

Visible to short-wave infrared (0.4–2.5 mm) spectral reflectance data were effective for mapping mineral assemblages on the surfaces of mine waste piles at the Elizabeth mine, Vermont. Three major assemblages displayed characteristic spectral features associated with jarosite, iron oxides, and muscovite, respectively, and were readily distinguishable in both ground-based and remote sensing spectral measurements.

Jarosite distributions on the Elizabeth mine tailings are largely controlled by hydrologic and topographic factors that do not necessarily reflect the underlying sulfide mineral distributions. Flat-lying areas on the tailings piles are surfaced by an oxidized layer of mainly goethitic wastes. Iron oxides also occurred in distinct zones fringing areas of jarositic waste. Relatively wet conditions at the time of our study precluded any extensive development of efflorescent iron sulfate minerals on the mine waste piles.

Novel Treatment for the Prevention of Secondary Adhesions
Authors: Obayan Adebola
Published: August 2024

Adhesion formation following surgical procedures poses a major clinical challenge, often leading to chronic pain, increased hospital readmissions, and substantial healthcare costs exceeding a billion dollars annually. Despite advancements in surgical techniques, minimally invasive approaches, and barrier methods, there is a lack of targeted research on preventing secondary adhesions after adhesiolysis. This study aims to bridge this gap in the literature by exploring novel treatment options. In our earlier research, alanyl-glutamine was shown to effectively prevent primary adhesions in a rat model involving polypropylene-type meshes, which are typically associated with severe adhesions despite their suitability for hernia repair. Building on these findings, we extended our investigation to determine if this treatment could also prevent secondary adhesions post-adhesiolysis. In this study, adhesions were induced in Wistar rats, followed by adhesiolysis and subsequent treatment with alanyl-glutamine. Six weeks posttreatment, the extent of adhesion formation was evaluated, revealing no adhesion formation. Our results demonstrate that alanyl-glutamine effectively prevents both primary and secondary adhesions in a rat model, highlighting its potential as a promising intervention to mitigate the adverse effects and complications associated with surgical adhesions.
Backstepping control of DFIG wind turbine system based rotor flux observer
Authors: Boureguig Kada , Ouagueni Fayssal , Chouya Ahmed , Sadouki Bouamama Réda
Published: August 2024

This paper introduces a novel approach to controlling a wind energy system based on a doubly fed induction generator (DFIG) using backstepping control. The proposed control method allows for independent control of the active and reactive power of the stator. Unlike traditional methods that rely on vector control of the stator fluxes and neglect the stator resistance, this approach takes into account the nonlinearities and coupled nature of the system. By using a nonlinear model in the Park frame, the control is more accurate and closer to the behavior of a real machine. This method has yet to consider any estimation of the rotor flux model. Using a high-gain observer can resolve the issue of measuring rotor flux. The stability of the nonlinear observer is demonstrated through the application of Lyapunov theory. The simulation results indicate that the suggested control scheme has enhanced the dynamic performance of the system.

Published: August 2024

Classifying tumors by type, grade, and stage is crucial for treatment decisions and predicting outcomes. Deep learning, especially Convolutional Neural Networks (CNNs), has significantly advanced tumor classification by effectively analyzing complex patterns in magnetic resonance (MR) images. This work presents a hybrid image classification method using the EfficientNetB0 model and Support Vector Machine (SVM) to categorize brain MR images into pituitary tumor, glioma tumor, meningioma tumor, and normal brain. EfficientNetB0 model extracts deep features from the images, which are then classified by a linear SVM. To significantly enhance classification accuracy for brain images, we use the Pareto algorithm to determine the penalty parameter C for the linear SVM. The testing results showed that the proposed system achieved a classification accuracy of 99.30%, recall of 99.30%, precision of 99.30%, and F1-score of 99.30%, with a high specificity of 99.77%. These results demonstrate that the combination of the Pareto algorithm and SVM significantly contributes to improved classification accuracy for brain images.

Published: August 2024

In this investigation, the estimation of global solar radiation was meticulously carried out within Ghardaïa city, a region situated in Southern Algeria, utilizing a sophisticated multilayer perceptron (MLP) neural network architecture. This research primarily concentrated on developing a predictive model based on a singular input parameter, specifically, the sunspot numbers, to forecast global solar radiation levels. The model's formulation was rooted in empirical data collected over an extensive period from 1984 to 2000, which was used for training the neural network. To assess the model's predictive accuracy and robustness, data from the years 2001 to 2004 were employed for validation purposes. The outcomes of this study were highly satisfactory, indicating that the MLP-based model possesses a significant predictive capability for Diffuse Global Solar Radiation (DGSR). This is substantiated by robust statistical metrics, including a normalized Root Mean Square Error (nRMSE) of 0.076, reflecting the model's accuracy in prediction, and a correlation coefficient (R) of 93.16%, denoting a strong correlation between the predicted and observed values. These results underscore the model's efficacy and potential application in accurately estimating global solar radiation in the specified region.

città e le leggi. Gride manoscritte e a stampa nella Milano del Cinquecento
Authors: Francalanci Marco
Published: August 2024

Durante l’età moderna le gride furono tra i documenti maggiormente utilizzati dalle istituzioni per comunicare al popolo regole e norme da seguire. La loro circolazione era affidata ai preconi, che con la loro voce dovevano rendere i documenti pubblici, affiggendone inoltre copia nei luoghi più rappresentativi e frequentati delle città. In tutta Europa se ne producevano quindi in numero amplissimo (sia in forma manoscritta che a stampa) nel tentativo di far conoscere e osservare le più recenti disposizioni.

Background: The high maternal mortality rate (MMR) indicates that maternal and child health (KIA) services must be improved. Applying a positive attitude to all patients is a way that health workers can increase patient satisfaction so that patients are interested in undergoing antenatal care to reduce MMR.
Objective: This study aims to determine the relationship between the attitude of health workers and patient satisfaction at the Maternal and Child Health Polytechnic (KIA) UPTD Puskesmas I East Denpasar
Method: This research uses a correlation analytical design with a cross-sectional study approach. Sampling used a non-probability sampling technique, namely consecutive sampling. The sample used was 172 respondents and the instrument used was a questionnaire.
Results: The results of the study showed that of the 172 respondents, the majority of respondents, namely 94 (54.7%) stated that the attitude of health workers was in the positive category and the majority of respondents, namely 90 (52.3%) stated that they were satisfied with the services provided by health workers. The results of the Spearman Rho test show that there is a significant relationship between the attitude of health workers and patient satisfaction, with a p-value <0.001
Conclusion: The more positive the health worker's attitude, the more satisfied the patient. So it is hoped that health workers can apply a friendly attitude, be polite and have empathy for all patients in order to increase patient satisfaction and reduce MMR

This study analyses the determinants of building energy efficiency in different climate zones and user types. The energy consumption of buildings in different climate zones can be affected by well-known determinants in different ways. So do the buildings with different user types. The primary aim of this study is to investigate how building energy efficiency is determined in five major climate zones and four main property types. This study uses the global building data (Points Achieved dataset) from the Leadership in Energy and Environmental Design (LEED) rating system 2010 to conduct three cross-sectional tests with logit regression models. The results confirm that the determinants of building energy efficiency are the location of the building, adoption of Building Energy Codes (BECs), climate zones, building types, regional economic development level (namely Gross National Income—GNI, Purchasing Power Parity—PPP) and population density. However, the impact of the determinants varies considerably in different climate zones or for different building types. This is the first empirical study exploring building energy efficiency and how it is determined in different climate conditions and user types. The findings are helpful for the stakeholders, such as policymakers, developers, and local authorities, when they hope to implement measures to improve building energy efficiency and the policy/regulation to boost it. Each building requires specific measures that suit its different climate zones or building types to enhance energy efficiency.

Published: August 2024

Digitization, a key aspect of Industry 4.0, presents a dual-faced scenario for traditional business models: it poses significant challenges but also offers opportunities for complete transformation. This dichotomy is particularly evident as numerous businesses acknowledge the imperative to digitize yet grapple with the question of where to initiate this process. Addressing this gap, the current study introduces a comprehensive methodology aimed at facilitating the onset of digital transformation in businesses. This methodology not only confronts the various challenges and complexities associated with digitization but also emphasizes a cycle of continuous development. Central to this approach is the integration of triggers for both creative and technological thinking within organizational structures. This aspect is crucial as it fosters an environment conducive to innovation and technological advancement, key drivers in the digital era. The practical applicability and effectiveness of this model have been demonstrated through its successful implementation in the German service industry. This validation not only underscores the model's relevance but also its potential as a blueprint for digital transformation in various business sectors, aligning with the evolving demands of Industry 4.0.
A Study on the Performance of Mergers and Acquisitions in the Context of State-Owned Enterprise Reform: The Case of Ansteel and Benxi Steel
Authors: Cai Yushan
Published: August 2024

The State-owned Assets Supervision and Administration Commission emphasizes that promoting the reorganization of state-owned enterprises (SOEs) can focus their advantageous resources, which plays a positive role in addressing issues such as the uneven distribution of state-owned capital, inefficient resource allocation, and homogenized development. This paper, set against the backdrop of SOE reform and central enterprise reorganization, uses the merger and reorganization event of Ansteel Group and Benxi Steel Group as a case study to investigate how central enterprise reorganization can improve the performance of central enterprises, based on the theory of synergistic effects. The study finds that under the theory of synergistic effects, after the reorganization of Ansteel Group and Benxi Steel Group, the operational, financial, and managerial synergistic effects of Ansteel Group continue to be realized, thereby enhancing the performance level of Ansteel Group. This paper aims to demonstrate the improvement of enterprise performance through central enterprise reorganization and calls on other central enterprises to actively respond to the national requirements for mergers and reorganizations, offering suggestions for subsequent reorganizations of central enterprises.

As the downward pressure on the world economy increases, the financial industry continues to suffer, especially private equity funds. In recent years, the frequent occurrence of major special events and hot news around the world cannot help but make people doubt whether these special events will have an impact on the valuation of private funds. This paper takes COVID-19, the most typical and influential special event in recent years, as an example, combined with various data during COVID-19, to discuss the impact of the epidemic on private equity valuation models and the private equity market. This paper finds that the COVID-19 pandemic has severely affected the valuation accuracy of discounted cash flow method and made the valuation of the market method lower than the true value of the company. While sectors such as real estate, tourism and hospitality and logistics have been severely negatively impacted by COVID-19, the pandemic has boosted sectors such as fintech, healthcare, pharmaceuticals and biotechnology. After the test of this epidemic, investors and management teams need to make timely adjustments to valuation models, while taking into account long-term market trends and industry changes, more prudently evaluate investment opportunities, and make sound investment decisions.
