Published: September 2022

Abstract
Based on the accident causation theory, the mechanism and inducement of construction safety risk in mining enterprises are clarified. The safety risk system of mining enterprises is divided into five subsystems : personnel, material equipment, technology, environment and management by rough set theory. The comprehensive weight of each risk factor is calculated by network analytic hierarchy process and fuzzy comprehensive evaluation method. Taking a mine in Shanxi Province as the research object, the causal traceability diagram and flow stock diagram of the risk system of mining enterprises are constructed by means of system dynamics model. The influence of various risk factors of the mine on the overall safety risk management level of the enterprise is simulated, and the numerical value of key technology influence factors is adjusted. The sensitivity changes of safety productivity and safety risk management level of mining enterprises in different situations are analyzed. The results show that: (1) The management and personnel subsystem has the greatest impact on the safety risk management of mining enterprises, followed by the technology, material equipment and environment subsystem. (2) Increasing safety input can improve the safety level and reduce the expected safety value time, otherwise it will reduce the safety level and delay the expected safety value time. (3) Further simulation of the technical subsystem, it is found that the factors affecting the safety level of mining enterprises are construction survey and monitoring, support structure, construction design, mining scheme and engineering technology application. (4) The conversion rate of safety technology input to engineering technology application and construction exploration and monitoring shows a “W” type development trend of decline-rise-slow decline-slow rise, mainly because the benefits of safety input have certain time delay and lag.

Published: September 2022

Abstract
This paper focuses on a photovoltaic system for pumping water since the use of photovoltaic energy has grown quickly due to its direct obtainability without pollution or noise. This paper proposes a new MPPT controller based on Takagi-Sugeno type fuzzy supervisors and a sliding mode controller. The first generate the maximum power point current under varying climatic condition whereas, the second allows tracking the reference signal produced by the fuzzy supervisor. The system includes a photovoltaic (PV) generator followed by a DC-DC Converter, DC bus, an AC/DC inverter which is connected to the induction motor. This later is coupled to a centrifuge pump. The induction motor is driven based on field oriented control strategy. The Takagi-Sugeno (T-S) type fuzzy supervisors predicts, depending on the variations of climatic variables such as irradiation and temperature, the optimum operating point for the photovoltaic source. The simulation results show the effectiveness of the proposed approach in transient and stationary regimes for different values ​​of climatic variables.
Three cycles of recurrent selection in four Spanish landraces of maize
Authors: Ordás Amando , Ordás Bernardo 
Published: September 2022

Abstract
Landraces of maize have a variability not found in the elite hybrids due to the bottleneck during selection. There is a renewed interest for using that variability, incorporating alleles for specific traits or widen the general variability of elite germplasm. In Europe, there is also an interest in the direct use of local landraces by farmer’s associations seeking for an agriculture that preserves crops diversity. Prebreeding programs are aimed to reduce the yield gap among landraces and improved materials. This paper shows the initial results of a prebreeding program consisting of three cycles of S₁ recurrent selection for grain yield in four local landraces from Northwestern Spain. All the populations had consistent yield gain in the first cycle of selection. However, the response in later cycles was different among the populations: one population had a continuous increase of 21% per cycle while two had reduced yield in the last cycles. Our results highlight the need to include secondary traits to avoid unintentional indirect effects. We conclude that, in prebreeding programs, it could be worthy to use large effective numbers to prevent inbreeding depression, particularly when the objective is the direct use of improved landraces. Another conclusion is that recurrent selection does not seem to be as efficient on European germplasm as it is on Corn Belt varieties. Finally, to obtain valuable new germplasm requires a sustained, long-term effort.

Published: September 2022

Abstract
Introduction and Objectives: There is substantial literature demonstrating minimal to no increased risk of 3-piece penile prosthesis (PP) complications for patients undergoing PP placement with concomitant reconstructive urologic procedures. However, there is a paucity of research investigating outcomes for patients suffering from erectile dysfuncton(ED) who undergo concomitant non-reconstructive urologic procedures at the time of PP placement.

Methods: A retrospective IRB-approved (IRB00205900) review of patients undergoing PP placement at Johns Hopkins from January 2007-July 2021 was conducted. We identified 330 patients who underwent PP placement and a second urologic procedure during this time. Of the 330 identified, 48 had a non-reconstructive urologic procedure done concurrently. A control group involving 127 patients (with etiology of ED from previous prostatectomy) who underwent PP placement after 2015 with no concomitant procedure was utilized.

Results: Concomitant procedure type was divided into: endoscopic n=24 (53.3%), penile n=9 (20.0%), scrotal n=10 (22.2%), neuromodulation n=1 (2.2%), and oncologic n=1 (2.2%). Median age and body mass index (BMI); while, overall infection and erosion rates were low between both cohorts (Table 1). Patients in the concomitant group were generally unhealthier with 49.7% having more than 2 co-morbidities vs only 37.2% in the control p=0.03.
Device infections were similar between the two groups: control n=2 (1.6%) vs concomitant n=1 (2.2%); though, not statistically significant p=0.78. Device erosions were also similar: control n=4(3.2%) vs concomitant n=2(4.4%); again, not statistically significant p=0.68. Patients who underwent future revision similar were also similar: control n=13(10.2%) vs. concomitant n=6 (13.3%) p=0.50.

Conclusions: To date, this retrospective analysis demonstrates the largest cohort of patients undergoing non-reconstructive urologic procedures at the time of PP placement. Our results demonstrate that concomitant (non-reconstructive) procedures do not increase the likelihood of prosthetic adverse events, regardless of concomitant procedure type.

Abstract
Purpose: To study vessel density (VD) on Optical Coherence Tomography Angiography (OCTA) at choroid, chorio-capillaries (CC) & various retinal levels in normal population & various stages of dry AMD & how these changes progress with increase in severity of the disease.
Methods: Prospective, observational , cross-sectional study done on 252 eyes of 132 patients presenting to tertiary care centre in Central India between February 2021 to January 2022. For study purpose, eyes were divided into 5 groups according to the size and number of the drusen, viz, Group 1: No AMD (<50 years) , Group 2: No AMD ( > 50 years) , Group 3 : Early AMD and Group 4 : Intermediate AMD & Group 5 : Advanced AMD. In all eyes , VD was measured at choroid , CC, Deep capillary plexus (DCP) of retina & superficial capillary plexus (SCP) of retina.
Results: There were total 61 males & 71 females in the study . The mean age in case cohort is 61.90 ± 7.97 years with 52 (51.48%) males and 49 (48.51%) females. At choroidal level, the mean vascular density differed significantly across diagnosis types in all the quadrants (p < 0.05). Similar was the observation at CC & DCP level. At SCP level, except in central quadrant, the differences for remaining quadrants were significant across the groups. At SCP & DCP increase in VD is seen in early AMD cohort compared to No AMD (> 50 years) cohort, which showed continuous reduction later in intermediate & advanced AMD cohort.
Conclusion: With increase in the severity of disease, significant reduction in VD is also seen in retinal plexuses, along with the changes in choroid & CC. These VD maps may play a role as non-invasive biomarkers for healthy & diseased aging.

Abstract
Neoplasms are common across the animal kingdom and seem to be a feature plesiomorphic for metazoans, related with an increase in somatic complexity. The fossil record of cancer complements our knowledge of the origin of neoplasms and vulnerability of various vertebrate taxa. Here, we document the first undoubted record of primary malignant bone tumour in a Mesozoic non-amniote. The diagnosed osteosarcoma developed in the vertebral intercentrum of a temnospondyl amphibian, Metoposaurus krasiejowensis from the Krasiejów locality, southern Poland. A wide array of data collected from gross anatomy and microstructure of the affected intercentrum reveals the tumour growth dynamics and pathophysiological aspects of the neoplasm formation on the histological level. The neoplastic bone mimics on the structural level the fast growing fibrolamellar bone, but on the histological level develops through a novel ossification type. The physiological process of bone remodelling inside the endochondral domain continued uninterrupted across the pathology of the periosteal part. Based on the results, we discuss our case study’s consistence with the Tissue Organization Field Theory of tumorigenesis, which locates the causes of neoplastic transformations in disorders of tissue architecture.

Published: September 2022

Abstract
Purpose
To assess the maxillary and mandibular donor sites on cone-beam computed tomography (CBCT) images using Mimics software.
Methods
This cross-sectional study was conducted on 80 CBCT scans. Data in DICOM format were transferred to Mimics software version 21, and a maxillary and a mandibular mask according to cortical and cancellous bones were virtually created for each patient based on Hounsfield units (HUs). Three-dimensional models were reconstructed, boundaries were defined for donor sites including mandibular symphysis, ramus, and coronoid process, zygomatic buttress, and maxillary tuberosity, and virtual osteotomy was conducted on the 3D models to harvest bone. The volume, thickness, width, and length of harvestable bone from each site were quantified by the software. Data were analyzed by independent t-test, one-way ANOVA, and Tukey’s test (alpha = 0.05).
Results
The greatest difference in harvestable bone volume and length was observed between ramus and tuberosity (P < 0.001). The maximum and minimum harvestable bone volumes were found in symphysis (1753.54 mm3) and tuberosity (84.99 mm3). The greatest difference in width and thickness was noted between the coronoid process and tuberosity (P < 0.001), and symphysis and buttress (P < 0.001), respectively. Harvestable bone volume from tuberosity, length, width and volume from symphysis, and volume and thickness from the coronoid process were significantly greater in males (P < 0.05).
Conclusion
The harvestable bone volume was the highest in symphysis followed by ramus, coronoid, buttress, and tuberosity. The harvestable bone length and width was the highest in symphysis and coronoid process, respectively. Maximum harvestable bone thickness was found in symphysis.
Carbon footprint (kg CO2e) expended in the aquaculture: Assessment of concrete pond rainbow trout farming from Türkiye
Authors: Diken Gürkan 
Published: September 2022

AbstractThe carbon footprint (CF) of animal production systems can estimate their standings against global protein demand. Turkey is the top rainbow trout producer in Europe, but surprisingly little is known about the CF of the production. This study aimed to evaluate the CF expended of concrete pond rainbow trout (CPRT) farming. The data were obtained from a farm with an annual project production capacity of 350 tonnes (APC) over a three-year production (TPY) with different harvest amounts. Total CF expended was the summation of CF expended on compound diets, general management, transportation and machinery, equipment, and construction. The total CF expended was calculated at 1.78 and 1.67 kg CO2e(equivalent) on average for TYP and APC, respectively. The TYP average values of CF expended per kg of protein deposited in harvested fish and CF expended per Mcal of cultural energy expended during production were 10.66 and 0.36 kg CO2e, respectively. The CF expended per 100 kcal food energy in harvested fish was calculated at 0.1263 and 0.1173 kg CO2eon average for TYP and APC, respectively. Aquafeed production and transportation are the important CF expended sources in CPRT. Future studies on CF expended of aquaculture farms must be species-specific and culture-specific.
Waste Activated Sludge Oxidation and Azo Dye Reduction in Microbial Fuel Cell: Optimization of process conditions for high electricity generation and waste treatability
Authors: PİŞKİN Elif DURNA , NevimGENÇ Nevim 
Published: September 2022

AbstractIn microbial fuel cells (MFC), oxidation and reduction processes occur simultaneously. In this study, the operating conditions affecting oxidation-reduction and electricity generation of MFC were optimized using the Taguchi Experimental Design model. Optimization was carried out for maximum power density, coulombic efficiency, azo dye removal and COD removal. With the determined optimum conditions (cathode pH of 3.0, cathode oxygen status of anaerobic, anode substrate of pre-treated, external resistance of 100 Ω, cathode electrode type of plain carbon, cathode electrode surface of 22 cm2, cathode conductivity of 20 µs/cm), 177.031 mW/m2power density, 7.50% coulombic efficiency, 91.266% azo dye removal efficiency and 21.612% COD removal efficiency were obtained. From the Pareto analysis, it was determined that the power density, coulombic efficiency and COD removal efficiency were most affected by the substrate type at the anode, and the azo dye removal was most affected by the catholyte pH. With the polarization curve, it has been determined that the maximum power density is 145.11 mW/m2and the internal resistance of the optimum MFC system is 243.3 Ω. The cyclic voltammogram performed with the optimum experiment was associated with oxidation and reduction reactions.
A dispersion equation of Rayleigh-type waves in transversely isotropic nonlocalmagneto-electro-elastic solids half-space
Authors: Xuan Tung Do 
Published: September 2022

Abstract
The purpose of this research is to present the dispersion equation of Rayleigh-type waves in transversely isotropic nonlocal magneto-electro-elastic (MEE) half-space. First, the characteristic equation in nonlocal MEE halfs-pace are derived from the constitutive equations and the form solution. Then, the dispersion equation which surface wave speed satisfies is derived from the free traction condition on the surface of half-space with consideration of electrically and magnetically short/open circuit conditions. Finally, based on the obtained dispersion equation, the influence of boundary conditions are investigated in this paper. Moreover, the dependence of velocities of plane waves on the direction of propagation as well as nonlocality parameter has been also illustrated.

Abstract
Major histocompatibility complex class I (MHC-I) proteins are expressed in neurons, where they regulate synaptic plasticity. However, the mechanisms by which MHC-I functions in the CNS remains unknown. Here we describe the first structural analysis of MHC-I, to resolve underlying mechanisms that explains its function. We demonstrate that Y321F mutation of the conserved cytoplasmic tyrosine-based endocytosis motif YXXΦ in MHC-I affects spine density and synaptic structure without affecting neuronal complexity. Furthermore, the impact of the Y321F substitution phenocopies the MHC-I null animals, demonstrating that reverse, outside-in signalling events sensing the external environment is the major mechanism that conveys this information to the neuron and this has an essential role in the regulation of synaptic plasticity.

Abstract
Background
Islets prepared for transplantation into type 1 diabetes patients are exposed to compromising factors that contribute to early graft failure necessitating repeated islet infusions for clinical insulin independence. Lack of reliable pre-transplant measures to determine islet viability severely limits the success of islet transplantation. We imaged cell autofluorophores using hyperspectral microscopy to characterise loss of viability in islets and define a non-invasive methodology for predicting transplant outcomes in mice.
Methods
Islet viability was compromised by exposure to oxidative stress (menadione), hypoxia (dimethyloxalylglycine), cytokine injury (TNF-α, IFNγ, and IL-1β), or warm ischemia (30- and 60-minute delayed pancreas collection). The impact of islet encapsulation in a conformal coating of hydrogen-bonded poly(N-vinylpyrrolidone)/ tannic acid (PVPON/TA) multilayer film was investigated. LED illumination produced excitation at 358 to 476 ± 5 nm in 18 steps, emission was detected using filters at 414, 451, 575, 594, and 675 ± 20 nm. Syngeneic (C57BL/6Ausb) mice with diabetes (alloxan tetrahydrate) were used to test viability on transplantation. Discriminative analysis and unsupervised principal component analysis were used to differentiate groups. Unmixing of spectral signals to identify component fluorophores was carried out using the unsupervised algorithm Robust Dependent Component Analysis (RoDECA).
Findings:
The autofluorophores NAD(P)H, flavins, collagen-I and cytochrome-C were successfully unmixed. Redox ratio (NAD(P)H/flavins) was significantly increased in islets exposed to ROS, hypoxia, cytokine injury and warm ischemia, typically driven by elevated NAD(P)H. Receiver operating characteristic assessment showed that our models were able to detect; oxidative stress (ROS) (AUC = 1.00) hypoxia (AUC = 0.69), cytokine exposure (AUC = 0.94), or warm ischemia (AUC = 0.94) compared to islets harvested from pristine anesthetised heart beating mouse donors. Significantly, we defined an unsupervised autofluorescent score for ischemic islets that accurately predicted restoration of glucose control in diabetic recipients. Similar results were obtained for islet single cell suspensions, suggesting translational utility in the context of emerging beta cell replacement strategies.
Conclusions
Hyperspectral microscopy of autofluorescence has the potential to give a non-invasive indication of islet viability, prior to transplantation. This would inform clinical decision making and enable patients to be spared transplantation attempts with no potential to reduce their dependence on exogenous insulin.

Published: September 2022

AbstractOccupational exposure to quartz dust is associated with fatal diseases. Quartz dusts generated by mechanical fracturing are characterized by a broad range of micrometric to nanometric particles. The contribution of this nanometric fraction to the overall toxicity of quartz is still largely unexplored, primarily because of the strong electrostatic adhesion forces that prevent isolation of the nano-fraction. Furthermore, fractured silica dust exhibits special surface features, namely Nearly Free Silanols (NFS), which impart membranolytic activity to quartz. Nanoquartz can be synthetized via bottom-up methods, but the surface chemistry of those crystals strongly differs from nanoparticles resulting from fracturing. We report here a top-down milling procedure to obtain a nanometric quartz that shares with fractured quartz the key surface properties relevant to toxicity. Ball milling was optimized by coupling dry and wet milling steps, using water as a dispersing agent, and varying milling times and rotational speeds. Nanoquartz with a strong tendency to form submicrometric agglomerates was obtained. Deagglomeration with surfactants or simulated body fluids was negligible. Partial lattice amorphization and bimodal crystallite domain size were observed. A moderate membranolytic activity, which correlated with the amount of NFS, signaled coherence with previous toxicological data. Membranolytic nanoquartz for toxicological investigations was obtained.

Published: September 2022

Abstract
In genetic studies and in practical improvement programs for soluble solids in tomatoes, large plant populations and several readings on individual plants or lines are often desired. Although comminuting whole fruit or representative fruit portions in a blender prior to straining through cheesecloth is a satisfactory and widely used method for sampling, a simple, rapid procedure that could be used in the field would hasten the rapid screening of genetic material.

Abstract
Ethylene hastens the ripening of fruits and is sometimes considered to be a ripening hormone (1). It also can regulate the flowering of bromeliads (2) as well as hasten deterioration of certain cut flowers (3). We are reporting accelerated flowering of bulbous iris after treating the bulbs with ethylene.
