Galvanic corrosion of carbon steel under concentration cell formation in MgCl2 solution as an inorganic pollutant and the effect of flow velocity

Abstract The wastewater of petroleum refineries consists of various corrosive pollutants that are harmful not only for human and living organisms but also for the equipment and materials exposed to it. The galvanic corrosion of carbon steel in MgCl2 solution as a pollutant in petroleum refinery wastewater was studied under concentration cell formation. The influence of different operating parameters on the galvanic corrosion established by concentration cell was studied, and the concept of concentration cell corrosion was examined and discussed versus experimental results. The effects of some operating conditions on the galvanic behavior, such as the concentration of MgCl2 (0–2500 ppm) and solution flow velocity (150–1000 rpm), on corrosion rate, corrosion potentials, and corrosion current were investigated. New findings regarding the effect of corrosive substance concentration and the hydrodynamics on the corrosion rate of each electrode and the galvanic current were reported. It was found that the corrosion rate of carbon steel in both cell poles increases with increasing MgCl2 concentration in both free and galvanic corrosion. Increasing MgCl2 concentration also led to an increase in the galvanic currents and the corrosion rate of the two electrodes. The flow velocity in either cell terminal considerably influences the potentials, corrosion rates of both electrodes, and the galvanic current passing in the cell. A high flow velocity in the compartment with the more negative potential caused polarity reversal on some occasions.
High Incidence of Epithelial Dysplasia in Oral Leukplakia: A Retrospective Study

“Oral leukoplakia” alludes to white keratotic plaques having excluded other known lesions and etiologic factors except smoking. Due to the potential of malignant transformation of this epithelial lesion, the purpose of the present case-series was to determine the clinical and histologic precancerous features of this lesion. The study was conducted at the oral medicine department at the dental faculty, Kerman. Demographic, clinical and histopathologic characteristics of biopsy proven oral leukoplakia cases were collected from the documented records from 1999 to 2017 and registered in pre-designed charts. Finally, out of the 47 patients, the consistency rate between the clinical and histologic diagnosis of this lesion was 85.1%. The incidence of epithelial dysplasia was 48.9% (38.3% mild, 8.5% moderate and 2.1% severe) whereas 53.2% of the lesions were non-homogenous and 66% of the patients were smokers. Inasmuch as dysplasia was reported in the approximately half of the cases, right diagnosis of leukoplakia should be done by the dentist to prevent malignant transformation. Proper understanding, recognising, identification and differentiating this lesion are necessary for proper treatment.
FMS Squat Assessment and 2D Video Motion Analysis as Screening Indicators of Low Back Pain: A Cross Sectional Case- Study

Aim: Low back pain (LBP) is a disabling condition to individuals in the United States and physical therapy (PT) has been proven to be a beneficial treatment by analyzing their movement patterns. The main objective of this study was to analyze the deep squat component of the Functional Movement Screen (FMS) as an indicator of LBP while simultaneously using 2-D analysis. Method: This cross-sectional case study included 36 participants that completed a total of six deep squats. Three raters scored the FMS score of each participant. Results: The association between FMS score and the presence of LBP showed to be insignificant (p=0.119). Knee joint angles with 2-D analysis demonstrated a moderate correlation (⍴=0.520) to those with LBP, as well as knee joint angles on the ground (⍴=0.461). Conclusion: This study concluded that the FMS deep squat assessment was not a objective indicator of patients with LBP whereas 2-D motion capture was an objective measure.

Efficient Hyper-Parameter Selection in Total Variation-Penalised XCT Reconstruction Using Freund and Shapire’s Hedge Approach

This paper studies the problem of efficiently tuning the hyper-parameters in penalised least-squares reconstruction for XCT. Discovered through the lens of the Compressed Sensing paradigm, penalisation functionals such as Total Variation types of norms, form an essential tool for enforcing structure in inverse problems, a key feature in the case where the number of projections is small as compared to the size of the object to recover. In this paper, we propose a novel hyper-parameter selection approach for total variation (TV)-based reconstruction algorithms, based on a boosting type machine learning procedure initially proposed by Freund and Shapire and called Hedge. The proposed approach is able to select a set of hyper-parameters producing better reconstruction than the traditional Cross-Validation approach, with reduced computational effort. Traditional reconstruction methods based on penalisation can be made more efficient using boosting type methods from machine learning.

Vitamin D deficiency and total shoulder arthroplasty complications

Introduction The primary objective of this study was to examine the relationship between vitamin D deficiency and implant-related and medical complications following total shoulder arthroplasty. Methods Using the PearlDiver database, patients who underwent total shoulder arthroplasty from 2005 to 2016 with vitamin D deficiency were identified. These were compared to a 3:1 control group matched by age, sex, and presence of a concomitant osteoporosis diagnosis. Primary outcome measures were implant-related complications (loosening, periprosthetic fracture, periprosthetic joint infection, and revision total shoulder arthroplasty) in addition to medical complications within 90 days of surgery. A multivariable logistic regression analysis was utilized to control for patient demographics and comorbidities. Results One thousand and six hundred and seventy-four patients with vitamin D deficiency were identified and compared to 5022 controls. There was a significantly higher rate of revision total shoulder arthroplasty in the vitamin D deficient patients compared to controls (2.3% versus 0.8%, odds ratio 3.3, p < 0.0001). After controlling for confounding variables, there were no significant differences in any of the remaining implant-related or medical complications with the exception of higher rates of urinary tract infections in patients with vitamin D deficiency. Conclusions Vitamin D deficiency is associated with a higher rate of all-cause revision total shoulder arthroplasty but not medical complications compared to controls. Level of evidence: Level III case control study
Flux Balancing Control of Ungapped Nanocrystalline Core-Based Transformer in Dual Active Bridge Converters

Transformer flux dc bias is a critical issue, impacting the reliable operation of dual active bridge (DAB) converters especially when ungapped high permeability nanocrystalline core is used. Steady state current dc bias can easily saturate ungapped nanocrystalline transformers, and it is even more dangerous in transient conditions. A dc bias model is proposed to analyze steady state dc bias in different load conditions. The magnetizing current detection is necessary for closed-loop control of dc bias; conductors’ position is shown to impact sensor noise, and it is analyzed in detail. To deal with both steady state and transient dc bias, a unified flux balancing control (UFBC) is proposed introducing a predictive bias suppression (PBS) method with closed-loop flux balancing control (CFBC). With the proposed PBS, both primary/secondary current balance and flux balance can be achieved within one switching cycle using UFBC. Power characteristics and interaction between power control and flux balancing control of DAB converters are analyzed, and the CFBC needs to work in a low bandwidth due to sensor bandwidth limitation and interaction between power control and flux balancing control. The UFBC is verified on a 300-kW cascaded DAB converter prototype.
Efecto de la infección con virus de la rabia sobre la estructura dendrítica de las células de Purkinje en el cerebelo de ratones

La rabia humana continua siendo un importante problema de salud publica en paises subdesarrollados por falta de control de la transmision canina y la presencia de reservorios silvestres (algunos murcielagos y carnivoros). En el presente trabajo se analizaron los efectos del virus de la rabia en la morfologia dendritica y en la expresion de la proteina MAP-2 en las neuronas de Purkinje del cerebelo, utilizando respectivamente la tecnica de Golgi y la inmunohistoquimica. Para esto, se inocularon ratones ICR con el virus de la rabia, por via intramuscular o intracerebral, y se sacrificaron posteriormente en la fase terminal de la enfermedad. Los cerebelos fueron removidos y cortados sagitalmente en un vibratomo, para posteriormente aplicar la bateria metodologica correspondiente para cada tecnica. Los cambios encontrados en la proteina MAP-2 mediante inmunohistoquimica no fueron estadisticamente significativos. Otros marcadores evaluados previamente por el grupo de investigacion en el cerebelo (calbindina y aldolasa) generaron resultados similares, lo que sugiere una posible respuesta diferencial de neuroproteccion en estas neuronas ante la infeccion con el virus de la rabia. Por el contrario, los resultados encontrados mediante la tecnica de Golgi arrojaron cambios significativos en la estructura del patron dendritico de las neuronas de Purkinje por causa de la infeccion, lo cual evidencia patologia dendritica de estas neuronas en los animales infectados con el virus. En conjunto, los resultados del presente trabajo aportan al conocimiento de la dinamica de la infeccion celular en la patogenesis de la rabia. La evidencia de dano neuronal estructural podria explicar en parte la fisiopatologia de esta enfermedad.
The complete chloroplast genome sequence of Rubus cochinchinensis

Abstract Rubus Linnaeus has long been deemed as one of the most diverse genera in family Rosaceae as well as an extremely challenging group with complicated intra-and-inter relationships at species level. These species are characterized by abundant diversity due to the tendency for hybridization, polyploidization, and agamospermy. There is a great deal of disagreement as to the identification, division of sections/subsections and phylogenetic history among a part of researchers. Hence, we assembled the complete chloroplast genome of Rubus cochinchinensis (MN913339) with 156,235 bp in total, composed of one large single copy-region (LSC, 85,845 bp), a small single-copy region (SSC, 18,848 bp) and a pair of inverted repeats (IRs, 51,542 bp). This genome contained 129 genes, including 8 rRNAs, 36 tRNAs, and 85 protein-coding genes and corporate CG content was 37.18%. Phylogenetic analysis provided a reliable basis for the divisions of tribes in the Rosaceae.
Cloning and Expression of ,-Carotene 15,15'-Dioxygenase

beta,beta-Carotene 15,15'-dioxygenase cleaves beta-carotene into two molecules of retinal and is therefore the key enzyme in beta-carotene metabolism to vitamin A. In the present study, it was possible to enrich the chicken beta,beta-carotene 15,15'-dioxygenase to such an extent that partial amino acid sequence information could be obtained to design degenerate oligonucleotides. With RT-PCR a cDNA fragment could be obtained and used subsequently in a radioactive screening of a chicken duodenal expression library. We cloned the first eukaryotic beta,beta-carotene 15,15'-dioxygenase which symmetrically cleaves beta-carotene at the 15,15'-double bond.
Milk consumption monitoring as a farmer friendly indicator for advanced treatment in limited fed calves with neonatal diarrhoea syndrome

The purpose of this study was to investigate whether milk consumption (MC) could be used as a simple farmer-friendly indicator for providing advanced treatment to limited fed diarrhoeic neonatal calves. Complementarily, it was evaluated whether the standard indications for veterinary care (severe dehydration and/or acidosis-septicaemia) are associated with different patterns in MC. The MC and health records of 103 calves with diarrhoeathat were fed a milk replacer at the volume of 10% of their body weight were used in the study. The MC reduction rate (MCRR) was calculated after each feeding (MCt) during the diarrhoea course, based on the MC prior to the diarrhoea onset for each calf (MC0) using the formula MCRR = 100 × (MC0 − MCt)/MC0. The calves were assigned into the ST group (n = 58) if they only received the standard treatment (oral rehydration solutions between milk feedings) until recovery, and into the advanced treatment (VT) group (n = 45) if they needed advanced treatment (i.v. fluids ± antibiotics) directly or after the standard treatment. The calves in the VT group that only had dehydration, were further assigned into the DH subgroup (n = 22) and those with signs of acidosis-septicaemia with or without dehydration were assigned into the ASD subgroup (n = 23). The MC was practically stable in the ST group throughout the diarrhoea course. In the VT group, the MC was significantly reduced during the last 36 hours prior to the advanced treatment administration. This reduction was significantly higher in the ASD subgroup than the DH subgroup. The MCRR on the last meal prior to treatment administration was proven to be a very reliable indicator for the detection of diarrhoeic calves needing advanced treatment (cut-off: ≥ 24.5%; sensitivity: 95.6%; specificity: 98.7%) and of those with acidosis-septicaemia (cut-off: ≥ 29.6%; sensitivity: 91.7%; specificity: 99.1%). The results of the study show thatfarmers employing this feeding regimen should seek veterinary assistance when the milk consumption of calves is reduced by ≥ 24.5%.
Better Edges not Bigger Graphs: An Interaction-Driven Friending Algorithm for the Next-Generation Social Networks

—Online social networks, such as Facebook, have been massively growing over the past decade. Recommender algorithms are a key factor that contributes to the success of social networks. These algorithms, such as friendship recommendation algorithms, are used to suggest connections within social networks. Current friending algorithms are built to generate new friendship recommendations that are most likely to be accepted. Yet, most of them are weak connections as they do not lead to any interactions. Facebook is well known for its Friends-of-Friends approach which recommends familiar people. This approach has a higher acceptance rate but the strength of the connections, measured by interactions, is reportedly low. The accuracy of friending recommendations is, most of the time, measured by the acceptance rate . This metric, however, does not necessarily correlate with the level of interaction , i.e., how much friends do actually interact with each other. As a consequence, new metrics and friending algorithms are needed to grow the next generation of social networks in a meaningful way, i.e., in a way that actually leads to a higher levels of social interactions instead of merely growing the number of edges in the graph of the given social network. This paper is a step towards this vision. We ﬁrst introduce a new metric to measure the accuracy of friending recommendations by the probability that they lead to interactions. We then brieﬂy investigate existing recommender systems and their limitations. We also highlight the side effects of generating easily accepted, but weak connections between people. To overcome the limitations of current friending algorithms, we present and evaluate a novel approach that generates friendship recommendations that have a higher probability of leading to interactions between users than existing friending algorithms.
Psychotherapeutische Maßnahmen und soziale Unterstützung in der Notfallambulanz

Komplexe Notsituationen profitieren insbesondere von einem Rahmen, der soziale und psychotherapeutische Optionen einschließt. Dafür ist die Anwendung des „Sozialen“ in seiner Grundbedeutung wichtig und überschneidet sich mit psychotherapeutischem Handeln. Die Kenntnis differenzieller Wirkungsaspekte erhöht die Behandlungsqualität bei Notfallpatienten zu einem frühen Zeitpunkt.
Lumbar Decompression and Interbody Fusion Improves Gait Performance, Pain, and Psychosocial Factors of Patients With Degenerative Lumbar Spondylolisthesis

Study Design: Prospective cohort study. Objective: Evaluate changes in gait, pain, and psychosocial factors among degenerative lumbar spondylolisthesis (DLS) patients before and 3 months after surgical intervention. Methods: Forty-four symptomatic DLS patients performed clinical gait analysis 1 week before surgery and 3 months after surgery. Patients performed a series of over-ground gait trials at a self-selected speed. Twenty-two matched asymptomatic controls underwent the same battery of tests. Three-dimensional motion tracking was used to analyze gait kinematics. Patient-reported outcomes, gait range of motion, and spatiotemporal parameters compared before and after lumbar decompression with fusion. Results: Surgical intervention resulted in significant improvements in walking speed (P = .021), stride time (P = .020), step time (P = .014), and single-support time (P = .038). Significant improvements in joint range-of-motion were found for knee (P = .002) and hip flexion (P = .006). Degenerative lumbar spondylolisthesis patients reported significant reductions in pain, disability, and improved psychological perceptions for fear-avoidance of pain and motion (all P < .001). Conclusions: Surgical treatment of DLS resulted in a faster, more efficient gait in addition to significant reductions in pain, disability, and psychological fear associated with pain and motion. These beneficial changes that we identified early in the postoperative period indicate that patients return to the quality of life they seek early on. Clinical gait analysis provides objective, quantifiable measures of gait parameters that provide new insight into both the preoperative disability associated with DLS and into the early postoperative function of patients during their rehabilitation.
A unique relationship between switching, mating and biofilm formation in the human pathogen Candida albicans

Candida albicans is the most prevalent human fungal pathogen. The research described in this thesis has focused on the identification and characterization of the regulatory pathways controlling white-opaque switching, mating, biofilm formation and the relationship among them in this pathogen. White-opaque switching and mating in C. albicans are under the repression of the a1-α2 complex. Based on this, a chromatin immunoprecipitation-microarray analysis of the a1-α2 target genes was conducted to search for the master switch locus. This analysis identified TOS9 (WOR1) as a master regulator gene, and overexpression of TOS9 resulted in a switch en masse from white to opaque. In 2006, a novel form of communication was demonstrated between white and opaque cells in C. albicans. It was shown that minority opaque cells through the release of pheromone signaled majority white cells of the opposite mating type to become cohesive, adhesive and form enhanced biofilms. These biofilms in turn facilitated opaque cell chemotropism required for opaque cell mating. To identify the pathway regulating the white cell pheromone response, deletion mutants were generated for select genes mediating the opaque cell mating response. It was demonstrated that the pathways regulating the white and opaque cell responses to the same pheromone share the same upstream components, including receptors, heterotrimeric G protein, and a mitogenactivated protein kinase cascade, but they use different downstream transcription factors that regulate the expression of genes specific to the alternative responses. This configuration, although found in higher, multicellular systems, is uncommon in fungi and suggests that it may be an antecedent to multicellularity in higher eukaryotes. In addition, it was found that a C. albicans-specific 55-amino-acid region of the first intracellular loop, IC1, of the α-pheromone receptor, is required for the α-pheromone response of white cells, but not that of opaque cells. Finally, to test the generality of the white cell pheromone response, evidence was presented that the response occurs in all tested media
Non-monotonic Lyapunov-Krasovskii functional approach to stability analysis and stabilization of discrete time-delay systems

In this paper, a novel non-monotonic Lyapunov-Krasovskii functional approach is proposed to deal with the stability analysis and stabilization problem of linear discrete time-delay systems. This technique is utilized to relax the monotonic requirement of the Lyapunov-Krasovskii theorem. In this regard, the Lyapunov-Krasovskii functional is allowed to increase in a few steps, while being forced to be overall decreasing. As a result, it relays on a larger class of Lyapunov-Krasovskii functionals to provide stability of a state-delay system. To this end, using the non-monotonic Lyapunov-Krasovskii theorem, new sufficient conditions are derived regarding linear matrix inequalities ( LMIs ) to study the global asymptotic stability of state-delay systems. Moreover, new stabilization conditions are also proposed for time-delay systems in this article. Both simulation and experimental results on a pH neutralizing process are provided to demonstrate the efficacy of the proposed method.
