Numerical and experimental study on the docking of a dynamically positioned barge in float-over installation

ABSTRACT The float-over installation method has become the best solution to offshore heavy topsides installations due to its flexibility and low cost. Dynamically positioned vessels can accurately keep position and track the predefined path with the help of thrusters, which eliminate the rigid requirements on auxiliary tugboats andmooring system. A precise control strategy is of critical importance to ensure the barge entering the slot successfully while keeping the impact with fenders within an acceptable limit. This paper establishes a time domain method to simulate the nonlinear motions during the docking stage. The barge is exposed to wind, wave and current forces to model the practical installation environment, and interactions between the barge and sway fenders are carefully taken into consideration. A model test is further conducted to validate the simulation results. Comparisons show that the proposed simulation programme can correctly simulate the docking stage of barge and predict the impact force of sway fenders.
Adaptation to Early-Season Soil Waterlogging Using Different Nitrogen Fertilizer Practices and Corn Hybrids

Excessive rainfall occurring in the early spring season in the Midwestern United States result in waterlogged soils contributing to corn production losses. The objective of our study is to evaluate the impact of soil waterlogging [non-waterlogged or waterlogged for 7 days when corn was at V3 growth stage (corn plant having three fully developed leaves with collar visible)], different pre-plant nitrogen (N) fertilizer sources and post-waterlogging rescue N fertilizer on grain and silage yield of two commercially available corn hybrids with different flood tolerance. Pre-plant N fertilizer was applied at 168 kg N ha−1. Nitrogen sources were a non-treated control (CO), polymer coated urea (PCU), urea (NCU), and urea plus Instinct (NCU + NI). A post-waterlogging rescue N fertilizer was applied at V7 as 0 or 83 kg N ha−1 of urea plus N-(n-butyl) thiophosphoric triamide (NBPT) (NCU + UI). Waterlogging decreased grain and silage yields in different years; however, significant interactions were observed among treatments. Rescue N applications increased grain yields by 6–46% in non-waterlogged treatments, but not in waterlogged treatments. The PCU and NCU + NI increased grain yields compared to the CO. Pre-plant N sources showed no significant differences in grain yield, probably due to existing environmental conditions or incorporation of fertilizer. The N source, application method, and timing for post-waterlogging rescue N application and flood-tolerant corn hybrids needs further investigation in poorly-drained claypan soils prone to waterlogging under a changing climate.
Biogeographical analyses to facilitate targeted conservation of orchid diversity hotspots in Costa Rica

We conduct a biogeographical assessment of orchids in a global biodiversity hotspot to explore their distribution and occurrences of local hotspots while identifying geographic attributes underpinning diversity patterns. We evaluate habitat characteristics associated with orchid diversity hotspots and make comparisons to other centres of orchid diversity to test for global trends. The ultimate goal was to identify an overall set of parameters that effectively characterize critical habitats to target in local and global orchid conservation efforts.
Bond strength of universal adhesive applied to dry and wet dentin

Aim: This study evaluated the influence of dentin wettability on the immediate and extended microtensile bond strength (mTBS) of a universal adhesive system used in the etch-and-rinse strategy. Methods: Twenty human third molars were selected and divided into four groups according to the adhesive system and dentin wettability. The mTBS values of each group were registered 24 h and one year after adhesive system application and resin composite block build-up (n=30). Data were analyzed by the t-test (p 0.05). However, the dry bonding reduced μTBS values of the Adper Single Bond 2 adhesive (p 0.05). Conclusions: Therefore, the Scotchbond Universal Adhesive can be applied to dry or wet dentin without compromising the etch-and-rinse bonding quality and the durability of the restorations.
Occurrence and Implications of the N-Acylethanolamine Metabolic Pathway in Physcomitrella patens

N -acylethanolamines (NAEs) with C12-C18 acyl chain are ubiquitous in seed plants and play a role in mediating abscisic acid (ABA)-dependent or -independent responses to stress. In moss Physcomitrella patens , using selective lipidomics approach, we recently identified the occurrence of anandamide or N -arachidonylethanolamide (NAE 20:4) and its precursors that were previously not reported in plants. Occurrence of anandamide in moss provides us with a unique opportunity to address if early land plants retained NAE-mediated signaling mechanism that is akin to animals but not to vascular plants. It is hypothesized that a distinctive NAE profile and metabolic pathway occurs in P. patens. To this extent, putative genes that might be responsible for anandamide metabolic pathway were identified and their expression levels were determined for three developmental stages of moss. The NAE metabolite levels and transcript levels for putative genes were higher in protonema stage and anandamide showed higher growth inhibitory effects, chlorophyll reduction, and putative gene induction than NAE 12:0, compared to ABA, when applied exogenously.
Fulfilling the Ethical Obligation to Political Participation: Clinical Social Workers and Professional Socialization

ABSTRACT In this exploratory study, the professional socialization of 23 clinical social workers based in New England is examined. Building on a landmark framework for understanding professional socialization, this article extends the conversation to assess professional identity among the study participants as well. Findings suggest that clinical social workers identify throughout presocialization, formal socialization, and practice after formal socialization as much or more with clinical roles in social work, especially as a psychotherapist or clinician, than as social workers invested in justice-oriented activities. Although all participants in the study associated justice with being a topic introduced in some social work courses or in evidence in some elements of clinical practice, most participants said that policy-related advocacy, organizing, and encouragement are not primary objectives of their clinical work and in many cases raise questions of the ethics of talking to clients about political participation at all. This paradoxical understanding of social work practice suggests a need for further exploration particularly of formal and postformal professional socialization so that clinical social workers will embrace social justice as part of the work that separates their profession from psychiatry, psychology, and counseling.

Measurements of atmospheric electricity in the Széchenyi István Geophysical Observatory, Hungary

Abstract. The Szechenyi Istvan Geophysical Observatory, also known as the Nagycenk Geophysical Observatory (NCK), was established in 1957. It has been the only measurement site in Hungary where observations of various parameters of the atmospheric global electric circuit are made in the framework of organized research under the umbrella of the Hungarian Academy of Sciences (MTA). Measurements of the atmospheric electrical potential gradient (PG) and Schumann resonances (SRs) running quasi-continuously in the observatory for decades provide an invaluable source of information for geophysical research. This paper gives an overview on the history of the observatory and particularly on various atmospheric electricity (AE) measurements on-site to commemorate the efforts and excellence of the people who served atmospheric sciences by dedicating their lives to obtaining high-quality, reliable data and scientific achievements at the highest possible level.
Comparison of the EMG Frequency Spectrum of Lower Limb Muscles during Weight Training with Traditional and Novel Equipment

Many practitioners and trainers advise designing and executing resistance training programs that include free weights and machines for strength training. The aim of the present study was to compare the frequency spectrum of lower limb muscles during weight training with traditional and novel equipment. Fourteen healthy power lifters (age: 26±7 years) were participated in this study. A portable EMG system with six pairs of bipolar surface electrodes was used to record the electrical activity of the selected lower limb muscles at a sampling frequency of 1200 Hz. Participants had enough experience to perform Free Weights Squat, Smith Machine Squat, Smith Machine Squat with one leg and the Dead lift movements. Participants carried out each movement, 5 times at an intensity equal to 50% of one-repetition-maximum level. The results showed higher median frequency of the vastus lateralis muscle during free weight single-leg squat than those that in the free weight squat (p=0.001) and dead lift (p=0.000) movements in lifting phase. Also, the median frequency of vastus lateralis muscle in single-limb squat with smith machine was significantly higher than that in the dead lift movement (p=0.021). The median frequency spectrum of the gastrocnemius muscle in the free weight squat movement showed a significant increase during the downward phase relative to the free weight single-leg squat movement (p=0.039). In order to strengthen vastus lateralis muscle in athletes or individuals with weak vastus lateralis muscle, free weight single-leg squat movement is more effective than those that in the other movements.

Transcriptomic Analysis Reveals Hormonal Control of Shoot Branching in Salix matsudana

Shoot branching is regulated by axillary bud activities, which subsequently grow into branches. Phytohormones play a central role in shoot branching control, particularly with regard to auxin, cytokinins (CKs), strigolactones (SLs), and gibberellins (GAs). To further study the molecular basis for the shoot branching in Salix matsudana, how shoot branching responds to hormones and regulatory pathways was investigated, and potential genes involved in the regulation of shoot branching were identified. However, how these positive and inhibitory processes work on the molecular level remains unknown. RNA-Seq transcriptome expression analysis was used to elucidate the mechanisms underlying shoot branching. In total, 102 genes related to auxin, CKs, SLs, and GAs were differentially expressed in willow development. A majority of the potential genes associated with branching were differentially expressed at the time of shoot branching in S. matsudana, which have more number of branching. These findings are consistent with the growth and physiological results. A regulatory network model was proposed to explain the interaction between the four hormones that control shoot branching. Collectively, the results presented here contribute to a more comprehensive understanding of the hormonal effects on shoot branching in S. matsudana. In the future, these findings will help uncover the interactions among auxin, SLs, CKs, and GAs that control shoot branching in willow, which could help improve plant structures through the implementation of molecular techniques in targeted breeding.
Evaluating translation of HIV-related legal protections into practice: a qualitative assessment among HIV-positive gay, bisexual, and other men who have sex with men in Manila, Philippines

ABSTRACT Legal protections for people living with HIV (PLHIV) are important for protecting human rights, yet little research has examined how laws translate into awareness and understanding for key populations. The Philippines has recently revised their legal protections for PLHIV in response to its growing HIV epidemic, where HIV-positive gay, bisexual and other men who have sex with men bear the majority of cases. We present findings from interviews with 21 HIV-positive gay, bisexual and other men who have sex with men in Manila, Philippines regarding awareness, understanding, and needs regarding HIV-specific legal protections at the time just before new revisions to the omnibus HIV law were passed. Overall, there was no standardized way participants became aware of legal protections; few became aware through healthcare providers, while most learned through online resources, social media, and advocacy organizations. However, even after learning about HIV-specific legal protections, many found the law too complex to understand or did not understand how to use such protections. This led participants to preemptively take action to avoid HIV-related discrimination, even if they were protected by law. Participants demonstrated a strong desire for interventions and policies to improve legal awareness and understanding for PLHIV, government officials, and private businesses. This research demonstrates the value of increasing awareness and understanding in policy-specific interventions designed to improve quality of life for PLHIV. Interventions centered around legal protections are currently underdeveloped, providing a strong opportunity to integrate such interventions in existing practice or as stand-alone tools to decrease perceived stigmatization.
A Neural Network-Based Spike Sorting Feature Map That Resolves Spike Overlap in the Feature Space

When inserting an electrode array in the brain, its electrodes will record so-called ’spikes’ which are generated by the neurons in the neighbourhood of the array. Spike sorting is the process of detecting and assigning these recorded spikes to their putative neurons. Many spike sorting pipelines rely on a clustering algorithm that groups the spikes coming from the same neuron in a pre-defined feature space. However, classical spike sorting algorithms fail when spike overlap, i.e., the near-simultaneous occurrence of two or more spikes from different neurons, is present in the recording. In such cases, the overlapping spikes segment ends up in a seemingly random position in the feature space and is not assigned to the correct cluster. This problem has been addressed before by extending the sorting algorithm with a template matching post-processor. In this work, a novel approach is presented to resolve spike overlap directly in the feature space. To this end, a neural network feature map is presented, that generates spike embeddings (feature vectors) that behave as a linear superposition in the feature space in the case of spike overlap. Its performance is quantified on semi-synthetic data obtained through a data augmentation procedure applied to real neural recordings.
Energy Security of Poland and Coal Supply: Price Analysis

Energy security is one of the most intensely debated topics. Majority of papers treat the issue from the hydrocarbon market perspective, but this research focuses on the coal market broken into two specific market segments: heating and electricity production. Using the case of Poland as an example, we conduct a cointegration analysis between the coal and natural gas markets. The study uses monthly data from 2011 until the beginning of 2019. Our results show that the Polish electricity sector is more connected to the international coal market than it is to the natural gas market, while the heating sector, despite using insignificant quantities of imported coal, is more connected to the natural gas market. Hence, energy security—in its price dimension—in those two market segments differs. This situation has important policy implications. First, energy policy should take this difference into account, and second, such variation implies that different market tools should be used in those market segments.
Thiazole-Bearing 4-Thiazolidinones as New Anticonvulsant Agents

Here, we describe the synthesis and anticonvulsant activity of thiazole-bearing hybrids based on 2-imino-4-thiazolidinone and 2,4-dioxothiazolidine-5-carboxylic acid cores. The structure of target compounds was based on the following: (i) A combination of two thiazole cores; (ii) similarity to ralitolin’s structure; (iii) the compliance with structural requirements for the new anticonvulsants. Target compounds were synthesized via known approaches based on Knoenavegel reaction, alkylation reaction, and one-pot three-component reaction. Anticonvulsant properties of compounds were evaluated in two different models—pentylenetetrazole-induced seizures and maximal electroshock seizure tests. Among the tested compounds 5Z-(3-nitrobenzylidene)-2-(thiazol-2-ylimino)-thiazolidin-4-one Ib, 2-[2,4-dioxo-5-(thiazol-2- ylcarbamoylmethyl)-thiazolidin-3-yl]-N-(2-trifluoromethylphenyl)acetamide IId and (2,4-dioxo-5- (thiazol-2-ylcarbamoylmethylene)-thiazolidin-3-yl)acetic acid ethyl ester IIj showed excellent anticonvulsant activity in both models. The directions of compounds modification based on SAR aspects were discussed. The results of the study provide a basis for further study of the anticonvulsant properties of selected thiazole-thiazolidinones.
Phytochemical, Antioxidant and Antibacterial Studies of Ethanolic and Methanolic Extracts of Aloe elegans Leaves gel

The study was aimed at investigating the phytochemicals, antioxidant and antibacterial activities of the ethanolic and methanolic extracts of Aloe elegans leaves gel. The phytochemical screening revealed the presence of phenols, flavonoids, anthraquinones, tannins, sapponins and terpenoids in both extracts. The antioxidant activities of both extracts were assayed using ferric reducing antioxidant power (FRAP), conjugated diene (CD) and peroxide value (PV) methods using sunflower oil (SFO) as the oxidizable substrate. The value for methanol and ethanol extracts of Aloe elegans leaves gel and the standard ascorbic acid in the ferric reducing power assay at 20 μg/mL were found to be 65.32%, 62.89%, 59.4% respectively. The peroxide value after 12 days at room temperature for the Sunflower oil (SFO) was found to be 45 mmol/L while the value for the substrate containing methanol, ethanol extract and vitamin E were found to be 36, 38, 43 mmol/L respectively. The value of the absorption coefficients of conjugated dienes resulted from oxidations of the methanol and ethanol extracts and vitamin E were found to be 3.006, 3.387, 4.306 gcmmL respectively. In all the antioxidant assays used, the methanolic extract was found to inhibit oxidation of sunflower oil to a better extent than its ethanolic counterpart. Relative to vitamin E, both extracts exhibited better antioxidant efficacy. In the antibacterial assay, both the extracts showed potent bactericidal effects against Escherichia coli and Staphyloccus aureus, though to a lesser extent than the standard antibiotic Gentamicin.
Mentoring strategies and their impact on social workers’ attitudes

Summary This study explored different mentoring strategies: simulations and case studies regarding ethical dilemmas involved with employment of intellectual developmental disability workers in supported employment using questionnaires of psychological empowerment, self-efficacy, and attitudes toward employing intellectual developmental disability workers in the free market. Participants were 83 social workers and 60 employers and were divided into simulations, case studies, and control groups. All participants in the simulations and case studies groups attended nine mentoring sessions throughout one year, where they completed questionnaires at the beginning, the end, and six months after mentoring. Findings The level of employers’ psychological empowerment and their positive attitudes toward employment of individuals with intellectual developmental disability in their organizations were higher than among the social workers, but the social workers’ self-efficacy level was higher. In addition, we found that mentoring using simulations had more influence than the case studies. The study findings showed that the more dynamic the mentoring, the greater the changes in psychological empowerment perceptions, self-efficacy, and attitudes toward employing intellectual developmental disability workers, both during the study and subsequently. Applications There is considerable importance in developing in-service training and active mentoring for all those involved in the challenges of supported employment. Simulations with participation of actors among social workers and employers, regarding ethical challenges in supported employment are the recommended mentoring methods, as compared to the case studies tested in the current study. Therefore, the study findings encourage the development of advanced mentoring processes among social workers and employers based on simulations, for coping with ethical challenges in supported employment.
