AbstractIn the Mediterranean Sea, where biological invasions constitute a serious threat, the combination of citizen science and social networks amplified the power of proper field studies, recording species that would have otherwise presumably passed unnoticed. Based on data collected on several Facebook groups, we hereby first report the presence of five fish taxa (Kyphosus sp., Heniochus intermedius, Pomacanthus imperator, Pomacanthus maculosus and Abudefduf sp.) new for the Mediterranean Egypt, revise their distribution in the Mediterranean Sea and discuss their possible introduction pathways. Finally, we provide some considerations on the potentiality of social media for citizen science projects.

Published: March 2021

AbstractSalmonella enterica is an important foodborne pathogen. Its rapid and reliable detection in food is critical for the effective prevention of the outbreak of foodborne diseases. Here, we report a novel method for the rapid, specific, label‐free, and real‐time detection of S. enterica with biolayer interferometry (BLI) using an antibody as the receptor. The limit of detection for S. enterica in buffer was 1.6 × 105 CFU/ml at a binding time of 300 s. This method enabled the successful identification of S. enterica in complex food matrices (whole egg powder and beef samples) with satisfactory recovery rates. This BLI‐based method holds great promise in serving as a novel diagnostic tool in the field of food safety and other related fields for the rapid, label‐free, specific, and real‐time detection of S. enterica.

Published: March 2021

AbstractPurposeThis article reviews the missions of the U.S. Department of Veterans Affairs (VA) and the evolution of its electronic health record (EHR), the Veterans Health Information Systems and Technology Architecture (VistA). This system, along with its clinical graphical user interface the Computerized Patient Record System, form a key link in VA health care. A Veteran who receives healthcare through the VA can have their EHR accessed by clinicians at any VA healthcare facility across the United States and its territories. Data aggregated daily at a corporate data warehouse supports VA quality improvement and research.Organizing ConstructServing over 9 million Veterans, the VA is one of the largest integrated healthcare systems in the United States. It has been a leader in the development and use of healthcare informatics, EHR, and big data analytics for over 30 years. Nurses engaged in major roles in the evolution of these developments.ConclusionsWith over 500 nurses as members, the Office of Nursing Informatics’ Field Alliance demonstrates the VA’s continuing commitment to fostering nursing informatics. The commitment includes investment by the VA to develop nursing informaticists from among its own staff.Clinical RelevanceExemplars of the impact of nursing informatics are shared. Future directions include an EHR that begins during military service and follows the Veteran into VA health care.

AbstractPurposeTo explore nurses’ perceptions of the organizational climate in general hospitals in Myanmar.Design and MethodsUsing a qualitative descriptive design, data were purposively collected from all levels of registered nurses in eight general hospitals across Myanmar during August to October 2019. Seventeen individual in‐depth interviews and eight focus group discussions with 65 nurses were undertaken and analyzed using Graneheim and Lundman’s qualitative content analysis.FindingsFour categories of organizational climate from a Myanmar nursing context emerged: organizational uniqueness, organizational alignment, sense of empowerment, and the reinforcing organization. Organizational uniqueness included the subcategories of perception of features and orientation of the organization, whilst organizational alignment comprised the three subcategories of the values inherent in the management process, the criteria of success, and strategic emphasis. The sense of empowerment category embraced the subcategories of the perceptions of the decision making and roles of leaders or managers; the last category, the reinforcing organization, incorporated the subcategories of bonding and recognition of the organization.ConclusionsThis was the first qualitative nursing study on nurses’ perceptions of organizational climate in Myanmar hospitals. Participants revealed a rich source of information that needs to be considered by hospital administrators and other policymakers to enhance quality clinical care by nurses, and their overall well‐being and working conditions. The emphasis on the holistic nature of this concept points to further investigations of working conditions, the lives of nurses, and management of nurses within the hospital environments in Myanmar hospitals, and can inform other countries.Clinical RelevanceNurses revealed a rich understanding of what an organizational climate represents or should represent, and they need to work with hospital administrators and managers to contribute to the development of positive organizational climate, which in turn should increase nurse retention and the efficacy of health care provided in hospitals.

AbstractWe herein report the case of a 28‐year‐old pregnant woman with an acute presentation of remarkable petechiae on her lower extremities and severe thrombocytopenia (16 000/mm3) at the 35th week of gestation. Although idiopathic thrombocytopenic purpura was initially suspected, subsequent examinations revealed that her ADAMTS13 (a Disintegrin And Metalloprotease, with ThromboSpondin type 1 repeats, member 13) titer was extremely decreased, while she was negative for antibodies against ADAMTS13. Infusion of fresh frozen plasma was immediately performed, and the platelet count was observed to increase. However, severe pregnancy‐induced hypertension and proteinuria emerged at 36 weeks and 2 days of gestation, and a male infant was delivered by emergency cesarean section on the 37th week of gestation. The postnatal development was uncomplicated. After delivery, although the mother's platelet count and ADAMTS13 activity decreased temporarily, both values increased following fresh frozen plasma transfusion. This case showed interesting aspects of congenital thrombocytopenic purpura (Upshaw–Schulman syndrome) in pregnancy. Moreover, the rapid measurement of the patient's ADAMTS13 activity and the subsequent accurate diagnosis of congenital thrombocytopenic purpura made it possible to treat the patient with fresh frozen plasma infusion and avoid contraindicated platelet infusion. Close cooperation between obstetricians, hematologists and pediatricians is necessary to achieve successful outcomes in cases of thrombocytopenic purpura during pregnancy.
Growth maximizing government size, social capital, and corruption
Authors: Carmeci Gaetano , Mauro Luciano , Privileggi Fabio 
Published: March 2021

AbstractOur paper intersects two topics in growth theory: the growth maximizing government size and the role of Social Capital in development. We modify a simple overlapping generations framework by introducing two key features: a production function à la Barro together with the possibility that public officials steal a fraction of public resources under their own control. As underlined by the literature on corruption, Social Capital affects public officials' accountability through many channels which also affect the probability of being caught for embezzlement and misappropriation of public resources. Therefore, in our endogenous growth model such probability is taken as a proxy of Social Capital. We find that maximum growth rates are compatible with Big Government size, measured both in terms of expenditures and public officials, when associated with high levels of Social Capital.

AbstractObjectiveTo explore the changes of peptidome profiles of saliva, serum, and gingival crevicular fluid (GCF) before and after non‐surgical periodontal treatment in patients with generalized periodontitis (stage I/II).Subjects and methodsSaliva, serum, and GCF samples were collected from 17 patients at baseline (T0), one week after ultrasonic supragingival scaling (T1) and eight weeks after subgingival scaling and root planning (T2). Matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS) was carried out to detect changes in peptidomic profiles. Then, nano‐liquid chromatography‐electrospray ionization‐tandem mass spectrometry (nano‐LC/ESI‐MS/MS) was performed to identify potential peptide biomarkers.ResultsMost of the peptides from the patients exhibited a decreasing trend from the time point of pretreatment to that of post‐treatment. Cluster analysis and scatter plots using these peptides indicated that salivary peptidome has an acceptable capability of reflecting the status of stage I/II generalized periodontitis. Seven of these peptides were successfully identified as α‐1‐antitrypsin, immunoglobulin κ variable 4‐1, haptoglobin, and immunoglobulin heavy constant γ2.ConclusionsCertain peptides in saliva, serum, and GCF were down‐regulated after non‐surgical periodontal treatment, demonstrating the application prospects of saliva in monitoring and surveillance of periodontal diseases in both clinical settings and communities.
Chemical and biochemical control of skin pigmentation with special emphasis on mixed melanogenesis
Authors: Wakamatsu Kazumasa , Zippin Jonathan H. , Ito Shosuke 
Published: March 2021

AbstractMelanins are widely distributed in animals and plants; in vertebrates, most melanins are present on the body surface. The diversity of pigmentation in vertebrates is mainly attributed to the quantity and ratio of eumelanin and pheomelanin synthesis. Most natural melanin pigments in animals consist of both eumelanin and pheomelanin in varying ratios, and thus, their combined synthesis is called “mixed melanogenesis.” Gene expression is an established mechanism for controlling melanin synthesis; however, there are multiple factors that affect melanin synthesis besides gene expression. Due to the differential sensitivity of the eumelanin and pheomelanin synthetic pathways to pH, melanosomal pH likely plays a major role in mixed melanogenesis. Here, we focused on various factors affecting mixed melanogenesis including (1) chemical regulation of melanin synthesis, (2) melanosomal pH regulation during normal melanogenesis and effect on mixed melanogenesis, and (3) mechanisms of melanosomal pH control (proton pumps, channels, transporters, and signaling pathways).
Why Those Biscuits Are Relevant and on the Sideboard
Authors: van Rooij Robert , Schulz Katrin 
Published: March 2021

AbstractIn this paper, we explain why the antecedent of a biscuit conditional is relevant to its consequent by extending Douvenʼs evidential support theory of conditionals making use of utilities. By this extension, we can also explain why a biscuit conditional gives rise to the inference that the consequence is (most likely) true. Finally, we account for the intuition that (indicative) biscuit sentences are false when the antecedent is false and allow for counterfactual biscuits.
Price and quality competitiveness across OECD countries: An approach to quality by R&D expenditure
Authors: Ben Hassine Haithem , Mathieu Claude 
Published: March 2021

AbstractThe aim of this paper is to analyse the effects of quality competitiveness based on technological innovation on the bilateral trade of goods. Our approach is based on the estimation of an import demand model that uses the data for 19 manufacturing sectors across 28 OECD countries over the period of 1998–2012. In the first step, to identify quality from prices, the logarithm of unit value (a proxy of price) is regressed on the logarithm of private R&D expenditure (a proxy for quality). The quality‐adjusted prices are derived from the difference between the unit value and its predicted value. In the second step, an import demand function is used to distinguish the effects of quality (private R&D expenditure) from the effects of other factors, such as production costs, which are approximated by the quality‐adjusted prices. The results of the first step indicate a significant positive effect of quality on the prices of imported goods in 7 out of 19 sectors. The results of the second step emphasise significant nonlinear effects of prices and quality on the import demand of goods: when the quality of imported goods is higher, the marginal effect of an increase in quality on the import demand is greater.

AbstractCanine oral malignant melanoma is locally invasive and highly metastatic. At present, the best option for local control is en bloc excision followed by radiation if excision margins are incomplete. Adjuvantly, the role of chemotherapy is dubious while immunotherapy appears encouraging. This retrospective study evaluated 155 dogs with oral malignant melanomas (24 stage I, 54 stage II, 66 stage III and 11 stage IV) managed in a single institution. The aim was to evaluate the differences in median survival time (MST) and disease‐free interval (DFI) between dogs which, at presentation, were treated surgically with a curative intent (group 1) vs those marginally excised only (group 2). MST in group 1 was longer than in group 2 (594 vs 458 days), but no significant difference was found (P = .57); a statistical difference was, however, found for DFI (232 vs 183 days, P = .008). In the subpopulation of vaccinated dogs, the impact of adjuvant anti‐CSPG4 DNA electrovaccination was then evaluated (curative intent, group 3, vs marginal, group 4); a significant difference for both MST (1333 vs 470 days, respectively, P = .03) and DFI (324 vs 184 days, respectively, P = .008) was found. Progressive disease was significantly more common in dogs undergoing marginal excision than curative intent excision for both the overall population (P = .03) and the vaccinated dogs (P = .02). This study pointed out that, after staging, wide excision together with adjuvant immunotherapy was an effective approach for canine oral malignant melanoma.
Compressible Flows Obtainable From Two-Dimensional Flows Through the Addition of a Constant Normal Velocity
Authors: Poritsky H. 
Published: March 2021

Abstract
This paper demonstrates that exact solutions of the flow of compressible fluids can be obtained by starting with two-dimensional steady-state flows and superposing upon them a velocity of constant magnitude and direction at right angles to the planes of the two-dimensional flows, while at the same time, the pressure, density, and temperature of the fluid at each point are unchanged. The procedure is demonstrated by several examples, one of which is of interest in connection with the discharge of exhaust gases from a gas engine through the tail cone and tail pipe in cases where the circulation has not been completely removed from the flow. Another example is the flow around a “sweepback” or “arrow” wing. This example is illustrated for supersonic flows on plane oblique shocks and on the Meyer-Prandtl expansion around an edge.
An Elementary Theory of the Bourdon Gage
Authors: Wolf Alfred 
Published: March 2021

Abstract
A theory of the Bourdon gage is presented based upon two elements of strain, namely, the bending of the walls in a transverse section through the gage tubing, and a longitudinal extension parallel to the axis of the tubing. Practical formulas are derived for the calculation of the sensitivity and the torque of the Bourdon gage. An estimate is made of the maximum stress. The sensitivity of a very thin-walled gage is shown to be proportional to the inverse first power of the wall thickness. Results of a few measurements show agreement with the theory.
Cylindrical Buckling of Sandwich Plates
Authors: Goodier J. N. 
Published: March 2021

Abstract
In the buckling of “sandwich plates” with a relatively easily deformed interior, or core, material, the core is not stiff enough to keep plane sections plane when the bending occurs. The core must then be analyzed according to the equations of plane strain, but the fact that the bending takes place in the presence of thrust means that terms representing the destabilizing tendency of the thrust must be included. The resulting problem is solved in the present paper for a sandwich plate in “cylindrical buckling”—that is in a mode analogous to that of the hinged column.
Forced Torsional Vibrations With Damping: An Extension of Holzer’s Method
Authors: Den Hartog J. P. , Li J. P. 
Published: March 2021

Abstract
An extension of Holzer’s method is given for the case of damped systems of discreet as well as of uniformly distributed inertias and flexibilities. For discreet systems the modification in the Holzer table consists of replacing I by I − jc0/ω, and of replacing k by k + jωci, whereby most numbers in the tables become complex. The meaning of the real part of any complex number is that quantity which is in time-phase with the motion at the free end, while the imaginary part is 90 deg out of time-phase with that motion. For distributed systems the results are given by Equations [12] and [12a] for a free forward end; by Equations [13] and [13a] for a damped forward end, while the letters a and b appearing in these results are defined by Equations [8] and [8a].
Heat Transfer Measurements Using Multiple Thermochromic Liquid Crystals in Symmetric Cooling Channels
Authors: Krille Tobias , Retzko Stefan , Poser Rico , von Wolfersdorf Jens 
Published: March 2021

Abstract
The transient thermochromic liquid crystal (TLC) method is applied to determine the distribution of the local heat transfer coefficients using a configuration with parallel cooling channels at an engine-relevant Reynolds number. The rectangular channels with a moderate aspect ratio and a high length-to-diameter ratio are equipped with one-sided oblique ribs with high blockage, which is a promising configuration for turbine near-wall cooling applications. In this arrangement, the three inner channels should experience same flow and thermal conditions. Numerical simulations are performed to substantiate this assumption. The symmetric single channels are sprayed with narrowband TLC with various indication temperatures. Multiple experiments were conducted. All start at ambient conditions before the fluid is heated up to several temperatures between 46 °C and 73 °C. The results show that the determined local heat transfer coefficients and therefore the Nusselt numbers vary significantly for the different experimental conditions especially at locations of high heat transfer coefficient behind the ribs. A simplified procedure with respect to measurement uncertainties is applied to enable an easy and fast valuation of the data quality. This might be used within the data reduction analysis for such experiments directly. The approach is illustrated using the obtained experimental data.
