Abstract
A critical issue in mine waste management is the management and mitigation of acid rock drainage and metal leaching particularly from waste rock. This requires good understanding and characterization of materials most likely to generate acid pH waters and generate leachable metals and metalloids, as well as the presence of minerals most likely to neutralize acidic pH such as carbonates and certain silicates. For low-sulfidation epithermal deposits in silica-rich volcanic rocks, neutralization minerals are rare. Consequently, determination of acid generation is almost entirely a function of sulfide content of the rocks. By understanding the distribution of sulfide minerals within such a deposit, an initial mine waste management plan can be developed.
The Rochester mine currently exploits a low-sulfidation epithermal gold-silver deposit and is located on the southern flank of the Humboldt Range in west-central Nevada. The Rochester mine is a conventional open-pit mining operation with cyanide heap leaching and Merrill Crowe processing. Silver and lesser gold mineralization occur associated with sulfide minerals hosted in Permian-Triassic Koipato Group rhyolitic units with extensive quartz-sericite-pyrite alteration. Gangue mineralogy of the deposit is dominated by slow or unreactive silicate minerals with little or no carbonate.
Silver-bearing mineralization was controlled by primary hypogene sulfides and secondary supergene oxidation processes, and most of the mineralized material mined to date has been fully or partially oxidized. Oxidation mobilizes and depletes all forms of sulfur from primary sulfide minerals. Due to the low sulfate content and low content of neutralizing gangue phases, the waste rock classification can be based on total sulfur content.
Based on the analysis of pulp samples collected from within the mine area, a sulfur block model was developed and compared to the results of standard acid-base accounting and net acid generation tests. This comparison demonstrates the benefit of the block model in identifying zones of potentially acid-generating material in the mined waste. Application of this information to mine planning has allowed more efficient management of acid-generating mine waste by allowing the operator to develop areas of the waste rock facility to receive the waste in a timely fashion. Such an approach is based on good mine geologic and mineralogical characterization and the use of a representative and comprehensive geologic block model.

Peran Laktat Pada Sepsis Dan Pemeriksaan Laboratoriumnya
Authors: Donaliazarti  
Published: August 2022

Abstract
Sepsis is a clinical syndrome due to infection and manifests as systemic inflammatory response syndrome (SIRS). Sepsis is a major cause of morbidity and mortality in hospitalized patients. In septic conditions, large amounts of lactate can be produced because of increased aerobic or anaerobic lactate production combined with decreased lactate clearance. Measurement of lactate levels is useful for detecting the presence of tissue hypoxia that is still not clearly visible so that therapy can be given earlier and clinician can monitor response to therapy. Increased lactate levels are also associated with decreased patient survival. A number of tools in the laboratory can be used to measure lactate level, including clinical chemistry analyzer, point of care testing (POCT) analyzer and blood gas analyzer. Methods for the examination of lactate are enzymatic, including the use of lactate oxidase and lactate dehydrogenase enzymes. Lactate plays an important role in the diagnosis of severe sepsis, as a prognostic indicator and monitoring response to therapy.

Abstrak
Sepsis merupakan suatu sindrom klinis akibat infeksi dan bermanifestasi sebagai systemic inflammatory response syndrome (SIRS). Sepsis merupakan penyebab utama morbiditas dan mortalitas pada pasien yang dirawat di rumah sakit. Pada kondisi sepsis, laktat dapat dihasilkan dalam jumlah yang besar oleh karena peningkatan produksi laktat secara aerob atau anaerob dan dikombinasi dengan penurunan klirens laktat. Pengukuran kadar laktat berguna untuk mendeteksi adanya hipoksia jaringan yang masih belum terlihat jelas sehingga dapat diberikan terapi lebih awal dan memantau respons terapi. Peningkatan kadar laktat juga berhubungan dengan penurunan kemampuan bertahan hidup pasien. Sejumlah alat di laboratorium dapat digunakan untuk melakukan pemeriksaan laktat di antaranya alat kimia klinik otomatis, alat point of care testing (POCT) dan alat blood gas analyzer. Metode untuk pemeriksaan laktat adalah enzimatik di antaranya menggunakan enzim laktat oksidase dan laktat dehidrogenase. Laktat berperan penting dalam diagnosis sepsis berat, sebagai indikator prognosis dan pemantauan respons terapi.

Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and Siro ozimeci Karaman sp. nov., from Austria and Croatia respectively, are described and illustrated. Both species show a close relation to two other relict sironid species from the southern and eastern parts of the Alps, Siro valleorum and Siro crassus. All four species are treated here as a monophyletic, alpine group of genus Siro, opposed to the remaining two European sironids, S. rubens and S. carpaticus (palaeoeuropean Siro group). The history of the alpine Siro group parallels the history of a part of the dynamic European archipelago in the Mediterranean Tethys area, which became a part of the Alpine orogeny. Diversification of the alpine Siro group is the result of the orogenic evolution of the Alps, linked to the Austroalpine and South Alpine tectonic units.

AbstractKey hurdles for replacing damaged cartilage with an equivalent synthetic construct are the development of a hydrogel with a strength that exceeds that of cartilage and fixation of this hydrogel onto the surface of an articulating joint. This article describes the first hydrogel with a tensile and compressive strength (51 and 98 MPa) that exceeds those of cartilage (40 and 59 MPa), and the first attachment of a hydrogel to a metal backing with a shear strength (2.0 MPa) that exceeds that of cartilage on bone (1.2 MPa). The hydrogel strength is achieved through reinforcement of crystallized polyvinyl alcohol with bacterial cellulose. The high attachment strength is achieved by securing freeze‐dried bacterial cellulose to a metal backing with an adhesive and a shape memory alloy clamp prior to infiltration and crystallization of the polyvinyl alcohol. The bacterial cellulose‐reinforced polyvinyl alcohol is three times more wear resistant than cartilage over one million cycles and exhibits the same coefficient of friction. These advances in hydrogel strength and attachment enable the creation of a hydrogel‐based implant for durable resurfacing of damaged articulating joints.
Strong and Tough Physical Eutectogels Regulated by the Spatiotemporal Expression of Non‐Covalent Interactions

Published: August 2022

AbstractPhysical eutectogels are appealing materials for technological devices due to their superior ionic conductivity, thermal and electrochemical stability, non‐volatility, and low cost. Nevertheless, current physical eutectogels are suffering from weak mechanical strength and toughness. Here, taking advantage of the distribution difference of polyvinyl alcohol (PVA) in water and deep eutectic solvents (DESs), a simple and universal solvent‐replacement approach is proposed to regulate the spatiotemporal expression of intra/interpolymer interactions to prepare strong and tough physical eutectogels. The exchange of DESs with water can restrengthen the weakened interactions between PVA chains in water, enabling PVA to crystallize to construct a uniform and robust polymer network. Consequently, the resultant PVA eutectogel exhibits record‐high strength (20.2 MPa), toughness (62.7 MJ m–3), and tear‐resistance (tearing energy Σ42.4 kJ m–2), while possessing excellent stretchability (Σ550% strain), repairability, and adhesive performance. Furthermore, this strategy is proven to be universally applicable to various species of polymers, and even can be utilized to fabricate continuous and conductive eutectogel fibers, demonstrating potential as engineering materials and wearable sensors.

Published: August 2022

AbstractRecent improvements in the performance of solution‐processed semiconductor materials and optoelectronic devices have shifted research interest to the diversification/advancement of their functionality. Embedding a molecular switch capable of transition between two or more metastable isomers by light stimuli is one of the most straightforward and widely accepted methods to potentially realize the multifunctionality of optoelectronic devices. A molecular switch embedded in a semiconductor can effectively control various parameters such as trap‐level, dielectric constant, electrical resistance, charge mobility, and charge polarity, which can be utilized in photoprogrammable devices including transistors, memory, and diodes. This review classifies the mechanism of each optoelectronic transition driven by molecular switches regardless of the type of semiconductor material or molecular switch or device. In addition, the basic characteristics of molecular switches and the persisting technical/scientific issues corresponding to each mechanism are discussed to help researchers. Finally, interesting yet infrequently reported applications of molecular switches and their mechanisms are also described.
