The New Developed Health Index for Power Transformer Condition Assessment

The accurate assessment of power transformer is vital for ensuring reliable and stable operation. Health index (HI) is developed to estimate the health condition. According to the characteristics of transformer, core dynamic parameters that can represent the transformer state are selected to calculate the health index: load, oil chromatography, partial discharge, infrared detection, grounding current of core and vibration. The transformer state is comprehensively evaluated from the perspectives of transformer thermal, electrical, mechanical and load. Then the transformer data is divided into different levels and parts, so multi-parameter statistical analysis is carried on. With the tool of statistical product and service solutions (SPSS), the relationship between the parameters is studied and weight is assigned. Based on contribution analysis, a health evaluation model is put forward. Public factor analysis is an approach to determine the relevance of each variable as well as the influence of diagnostic results on HI. Results obtained by multivariate analysis are also provided to demonstrate the validity and feasibility of assessment model.
A Wind Farm Frequency Control Method Based on the Frequency Regulation Ability of Wind Turbine Generators

The frequency control ability and strategy of wind turbine generators in wind farms are different. Decentralized control is difficult to meet the demand of a flexible control of a wind farm, which improves the requirement of coordinated control of wind farms to participate in system frequency regulation. In this paper, a wind farm frequency control method based on the frequency regulation ability of wind turbine generators is proposed, and a hierarchical control system structure is designed to coordinate the wind turbine generators to improve the system frequency according to the system frequency response characteristics. Simulation results show that the proposed method can improve the frequency control effect and effectively reduce the number of wind turbines participating in frequency regulation.
Resolution of Streptococcus suis Serotypes 1/2 versus 2 and 1 versus 14 by PCR-Restriction Fragment Length Polymorphism Method

Streptococcus suis is an important pathogen of pigs but is also transmissible to humans, with potentially fatal consequences. Among 29 serotypes currently recognized, some are clinically and epidemiologically more important than others. This is particularly true for serotypes 2 and 14, which have a large impact on pig production and also on human health. Conventional PCR-based serotyping cannot distinguish between serotype 1/2 and serotype 2 or between serotype 1 and serotype 14. ABSTRACT Streptococcus suis is an important pathogen of pigs but is also transmissible to humans, with potentially fatal consequences. Among 29 serotypes currently recognized, some are clinically and epidemiologically more important than others. This is particularly true for serotypes 2 and 14, which have a large impact on pig production and also on human health. Conventional PCR-based serotyping cannot distinguish between serotype 1/2 and serotype 2 or between serotype 1 and serotype 14. Although serotype 1/2 and serotype 2 have a very similar cps locus, they differ in a single-nucleotide substitution at nucleotide position 483 of the cpsK gene. Similarly, serotypes 1 and 14 have a very similar cps locus but also differ in the same nucleotide substitution of the cpsK gene. Fortunately, this cpsK 483G→C/T substitution can be detected by BstNI restriction endonuclease. A PCR-restriction fragment length polymorphism (RFLP) detection method amplifying a fragment of the cpsK gene digested by BstNI restriction endonuclease was developed and tested in reference strains of these serotypes and also in field isolates.
Optimal Scheduling in Smart Grids with Prediction Error Probability Limitation

We consider demand response, supply management and power scheduling in a smart grid in the presence of renewable energy sources. We maximize the total social welfare while constraining the probability of renewable forecast error, and solve the ensuing optimization problem to derive the best conventional power production and user consumption schedules. The resulting optimal policies demonstrate their superiority over a competing policy in terms of social welfare, particularly when the constraint is tight.
Drivers of Mobile Health Acceptance and Use From the Patient Perspective: Survey Study and Quantitative Model Development

Background Mobile health (mHealth) has potential to play a significant role in realizing a reversal of the current paradigm in health care toward a more patient-centric and more collaborative system to improve the outcomes obtained along with the quality and sustainability of health care systems. Objective The aim of this study was to explore and understand individual mHealth acceptance drivers between two groups of users: those with chronic health conditions and those without. Methods The extended unified theory of acceptance and usage of technology (UTAUT2) was enhanced with a new health-related framework: behavior intention to recommend and new mediation effects. We applied partial least squares (PLS) causal modeling to test the research model. Results We obtained 322 valid responses through an online questionnaire. The drivers of behavior intention with statistical significance were performance expectancy (β=.29, P<.001), habit (β=.39, P<.001), and personal empowerment (β=.18, P=.01). The precursors of use behavior were habit (β= .47, P<.001) and personal empowerment (β=.17, P=.01). Behavior intention to recommend was significantly influenced by behavior intention (β=.58, P<.001) and personal empowerment (β=.26, P<.001). The model explained 66% of the total variance in behavior intention, 54% of the variance in use behavior, and 70% of the variance in behavior intention to recommend. Conclusions Our study demonstrates a significant role of personal empowerment, as a second-order construct, in the mHealth acceptance context. The presence of a chronic health condition predicates an impact on acceptance of this technology.
Isolation, in vivo characterization, and safety validation of nitrate reductase active Lactobacillus fermentum NCIMB 702342 and its implications in addressing metabolic disease

Lactobacillus is a diverse genus of lactic acid bacteria with many strains that have been used for food fermentation. Given their historic use in foods and the ability of some strains to reduce nitrate, these bacteria are perfect candidates as a promising probiotic for treating metabolic disease. Herein, a nitrate reductase active lactobacillus was isolated from a library of candidate bacteria and an assay was developed to quantify its enzymatic activity. Moreover, a study was conducted to assess the strain’s nitrate reductase activity in vivo following induced hypertension using N-nitro-L-arginine methyl ester (LNAME) in an animal study. The results indicated that the probiotics did not result in attenuation of hypertension; however, the isolated strain, L. fermentum NCIMB 72023, may potentially reduce systemic nitrate to nitrite. Furthermore, safety validation was performed on Lactobacillus fermentum NCIMB 702342. Species-level identity was achieved through metabolic and genetic techniques and confirmed that the strain was a Lactobacillus fermentum. Although L. fermentum NCIMB 702342 was found to be resistant to clindamycin, the strain was susceptible to 7 other antibiotics. Furthermore, formation of metabolic by-products and antimicrobial agents were not observed. In summary, L. fermentum NCIMB 702342 was isolated from a library of candidate strains for its nitrate reductase activity, an assay was developed to quantify it enzymatic rate, an in vivo strain efficacy trial was conducted, and preliminary in vitro safety were assessed.
Allozyme diversity and morphometrics of the endangered Melocactus glaucescens (Cactaceae), and investigation of the putative hybrid origin of Melocactus × albicephalus (Melocactus ernestii × M. glaucescens) in north-eastern Brazil

Melocactus glaucescens (Cactaceae) is a critically endangered species endemic to northeastern Brazil. It grows in sympatry with other congeneric species and there is evidence for hybridization among them. We evaluated the levels of genetic and morphological variability and their substructuring between populations of M. glaucescens and sympatric species, and we tested for the occurrence of natural hybridization. Genetic variability was investigated using 12 allozyme loci, and morphological variability was investigated using multivariate morphometric analyses of 18 vegetative characters in nine natural populations of M. glaucescens , Melocactus ernestii , Melocactus concinnus and two distinct morphs of putative hybrids ( Melocactus ¥ albicephalus ). Genetic variability was low in all populations ( P = 7.7–41.7, A = 0.3–1.7, H e = 0.009–0.096), and all taxa displayed a deficit in heterozygotes. Low genetic structuring and moderate morphological structuring were found for M. glaucescens ( F ST = 0.045, A MRPP = 0.16) and M. concinnus ( F ST = 0.022, A MRPP = 0.11). The results obtained are inconclusive with respect to confirming the hypothesis of occurrence of hybridization because of an absence of diagnostic loci in the presumed parental species. The presence of several private alleles and the absence of linkage disequilibrium in the putative hybrids indicate that M. albicephalus should be treated as a distinct species, and not given hybrid status as recently stated by a number of authors. The large number of exclusive alleles and the levels of morphological structuring in the populations of M. glaucescens are important factors that need to be considered in the definition of strategies for the conservation of this species.

Micropropagation of some Malaysian banana and plantain ( Musa sp. ) cultivars using male flowers

Male inflorescences have potential to be used as explants for rapid micropropagation of Musa sp. The male flowers of four banana cultivars, namely ‘Berangan’, ‘Rastali’, ‘Nangka’ and ‘Abu’ belonging to three genome types in Musa (AAA, AAB, and ABB), were cultured onto Murashige and Skoog (MS) medium which was supplemented with 1 mg/L of TDZ, BAP, Kin, 2-ip and Zea. The number of shoots was found to significantly increase in both TDZ and BAP treatments, as compared to other cytokinins. TDZ at 0.4, 0.6 and 0.8 mg/L, in particular, appeared to be optimum for shoot induction in ‘BeranganAAA’, ‘Rastali-AAB’ and ‘Nangka-AAB’ and ‘Abu-ABB’, respectively. However, all the cultivars showed their highest response to regeneration at 8 mg/L of BAP. After the initiation of the explants onto the MS media for all the cultivars, the highest number of cauliflower-like bodies’ (CLBs) clusters was observed at two months of culture. The number of induced ‘CLBs’ cluster is dependent on the size of male buds. Male inflorescences with the size of 20 mm were found to induce more ‘CLBs’ clusters. Meanwhile, the number of shoots produced is dependent on both the cytokinins and cultivars used.
The associations of interstitial lung abnormalities with cancer diagnoses and mortality

An increased incidence of lung cancer is well known among patients with idiopathic pulmonary fibrosis. It is not known whether interstitial lung abnormalities, i.e. early fibrotic changes of the lung, are a risk factor for lung cancer in the general population. The study's objective was to assess whether interstitial lung abnormalities were associated with diagnoses of, and mortality from, lung cancer and other cancers. Data from the AGES-Reykjavik study, a cohort of 5764 older Icelandic adults, were used. Outcome data were ascertained from electronic medical records. Gray's tests, Cox proportional hazards models and proportional subdistribution hazards models were used to analyse associations of interstitial lung abnormalities with lung cancer diagnoses and lung cancer mortality as well as diagnoses and mortality from all cancers. There was a greater cumulative incidence of lung cancer diagnoses (p<0.001) and lung cancer mortality (p<0.001) in participants with interstitial lung abnormalities than in others. Interstitial lung abnormalities were associated with an increased hazard of lung cancer diagnosis (hazard ratio 2.77) and lung cancer mortality (hazard ratio 2.89) in adjusted Cox models. Associations of interstitial lung abnormalities with all cancers were found in models including lung cancers but not in models excluding lung cancers. People with interstitial lung abnormalities are at increased risk of lung cancer and lung cancer mortality, but not of other cancers. This implies that an association between fibrotic and neoplastic diseases of the lung exists from the early stages of lung fibrosis and suggests that interstitial lung abnormalities could be considered as a risk factor in lung cancer screening efforts. Interstitial lung abnormalities are associated with an increased hazard of lung cancer diagnosis and lung cancer mortality in a general population cohort. Cancers other than lung cancer were not associated with interstitial lung abnormalities. https://bit.ly/3hWdc6m
Feature Point Registration Model of Farmland Surface and Its Application Based on a Monocular Camera

In this study, an image registration algorithm was applied to calculate the rotation angle of objects when matching images. Some commonly used image feature detection algorithms such as features from accelerated segment test (FAST), speeded up robust features (SURF) and maximally stable extremal regions (MSER) algorithms were chosen as feature extraction components. Comparing the running time and accuracy, the image registration algorithm based on SURF has better performance than the other algorithms. Accurately obtaining the roll angle is one of the key technologies to improve the positioning accuracy and operation quality of agricultural equipment. To acquire the roll angle of agriculture machinery, a roll angle acquisition model based on the image registration algorithm was built. Then, the performance of the model with a monocular camera was tested in the field. The field test showed that the average error of the rolling angle was 0.61°, while the minimum error was 0.08°. The field test indicated that the model could accurately obtain the attitude change trend of agricultural machinery when it was working in irregular farmlands. The model described in this paper could provide a foundation for agricultural equipment navigation and autonomous driving.
Comparative studies on vertical-channel charge-trap memory thin-film transistors using In-Ga-Zn-O active channels deposited by sputtering and atomic layer depositions

Vertical-channel charge-trap memory thin film-transistors (V-CTM TFTs) using oxide semiconductors were fabricated and characterized, in which In-Ga-Zn-O (IGZO) channels were prepared by sputtering and atomic-layer deposition (ALD) methods to elucidate the effects of deposition process. The vertical-channel gate stack of the fabricated device was verified to be well implemented on the vertical sidewall of the spacer patterns due to excellent step-coverage and self-limiting mechanisms of ALD process. The V-CTM TFTs using ALD-IGZO channel exhibited a wide memory window (MW) of 15.0 V at a VGS sweep of ±20 V and a large memory margin of 1.6 × 102 at a program pulse duration as short as 5 ms. The programmed memory margin higher than 105 did not experience any degradation with time evolution for 104 s. The mechanical durability was also evaluated after the delamination process of polyimide (PI) film. There were no marked variations in charge-trap-assisted MW even at a curvature radius of 1 mm and programmed memory margin even after repeated program operations of 104 cycles. The introduction of ALD process for the formation of IGZO active channel was suggested as a main process parameter to ensure the excellent memory device characteristics of the V-CTM TFTs.
Autotomy‐induced life history plasticity in band‐legged ground cricket Dianemobius nigrofasciatus

Crickets can autotomize their limbs when attacked by predators. This enables them to escape death, but imposes a short‐term cost on their escape speed and a long‐term cost on their future mating ability. Therefore, adaptive response compensated for the cost of autotomy might be advantageous for autotomized individuals. In the present study, we examined whether autotomy induced life history plasticities compensating for the future cost in the band‐legged ground cricket Dianemobius nigrofasciatus. Life history traits of D. nigrofasciatus were compared between autotomized and intact individuals. The developmental time and head width of the individuals that were autotomized as fourth instar nymphs were significantly shorter and smaller, respectively, than those of intact individuals. However, the adult longevity, number of eggs laid and oviposition schedule did not vary between autotomized and intact individuals. In addition, there was no difference between individuals autotomized at the fourth instar and adult stages in these three traits. Early maturation in the autotomized individuals might be advantageous through reducing the risk of predation owing to the shorter period in nymphal stages. The cost of small body size in the autotomized females might not be so great because of no significant difference in fecundity between autotomized and intact individuals. However, the cost of small body size was unclear in the autotomized males because in general larger males were preferred by females. These results indicated autotomy‐induced life history that might reduce the cost of autotomy.
Twelve tips for teaching the International Classification of Functioning, Disability and Health with a view to enhancing a biopsychosocial approach to care

Abstract The World Health Organization International Classification of Functioning, Disability and Health has the power to shape professional behaviour and positively influence all aspects of health and social care practice. The visual depiction of the ICF framework belies the complexity of this multifaceted classification and coding system which students and practitioners can find challenging to grasp. This guide offers twelve integrated practical tips to help health and social care educators embed the ICF throughout the curriculum with a view to supporting student learning and ultimately interprofessional and inclusive practice.
Influence of Dentine Pre-Treatment by Sandblasting with Aluminum Oxide in Adhesive Restorations. An In Vitro Study

Dentine pretreatment through sandblasting procedures has been widely studied but no curve test results are currently available. Thus, the aim herein was to in vitro compare the adhesive strength in sandblasted or not samples using a universal testing machine. Thirty -two bovine teeth were divided into two groups, namely test (n = 16 bars), sandblasting with aluminum oxide particles (50 µm) was performed before the adhesion procedures), and control (n = 16 bars), where no sandblasting procedure was performed. A bi-material curve test was used to evaluate the characteristics of the dentine pretreatment in terms of tensile stress and fracture strength. A scanning electron microscope (SEM) was used to analyze the fracture topography in the composite, bonding, dentin, and at the relative interfaces. The results demonstrated a statistically significant difference between the two groups in terms of tensile stress at maximum load showing values of 84.300 ± 51.342 MPa and 35.071 ± 16.609 MPa, respectively for test and control groups (p = 0.033). Moreover, a fracture strength test showed values of 18.543 ± 8.145 MPa for test and 8.186 ± 2.833 MPa for control group (p = 0.008). In conclusion, the sandblasting treatment of the dentine significantly influenced the mechanical resistance of the adhesion in this in vitro study.
Developmental Changes in Cell Wall of Bundle Sheath Fibers Close to Phloem of Fargesia yunnanensis

The developmental changes of fiber wall in the bundle sheathes close to phloem of Fargesia yunnanensis including wall thickness and number of cell wall layers from 0.5 months of bamboo shoots emerged from the ground to 36 months old were investigated. The study revealed that culms of F. yunnanensis have two types of vascular bundles and the fibers adjacent to the phloem developed earlier than other fibers. There are two obviously developmental stages in fiber wall thickening during the first growth year. Six fiber wall types could be distinguished in the bundle sheath fibers close to phloem of 36 months old culms and lots of fibers with relatively big lumina at the periphery still could be observed. Two main deposition ways could be found in the developmental phase of bundle sheath fibers close to phloem.
Dispersal of Ichthyophthirius multifiliis (Ciliophora)

Ichthyophthirius multifiliis, Fouquet 1876, is a ciliate that parasitizes a wide variety of freshwater fish. Its life cycle includes a tissue-dwelling trophont, which departs upon maturity to become a free-living tomont, the stage that divides repeatedly to produce a new generation of infective individuals (1). Dispersal of the tomont, either at maturation of the trophont or upon death of the host, depends on differentiation of several organelles (2). Typically the tomont swims for 2-6 hr, then encysts (3). Little is known of the temporal pattern of departure by a population inhabiting a host or of reactions of the free-swimming tomonts to light. The objectives of the present study were to describe the temporal pattern of dispersal and determine the effect of light upon the pattern of encystment by the tomonts.
