Pelagic N2 fixation dominated by sediment diazotrophic communities in a shallow temperate estuary

Estuaries receive substantial anthropogenic nitrogen loading and are mainly considered net nitrogen sinks. While several studies have identified diverse diazotrophic communities in estuarine sediments, the role of pelagic diazotrophs in these systems is not well understood. We investigated the links between diazotrophic community composition, nitrogenase (nifH) gene expression, N2 fixation, and environmental conditions in Narragansett Bay (USA). Pelagic N2 fixation rates ranged between 0.02 and 9.41 nmol N L−1 d−1 and correlated significantly with fluctuations in diazotroph community composition. These fluctuations were also correlated with temperature, salinity, and mean sea level. The dominant sequences in our pelagic samples were related to sequences previously detected in the bay's sediments and were dominated by nifH gene Clusters I and III. We interpret this as a coupling between sediment and pelagic diazotroph communities and speculate that resuspension plays an important role for pelagic N2 fixation in shallow estuarine environments such as Narragansett Bay. For instance, the finding of active sulfate reducers in the oxygenated water illustrates that the sediment‐pelagic coupling can impact nutrient cycling in shallow environments. The pelagic N2 fixation measured during our study period showed only a minor contribution (< 1%) to the total estimated nitrogen load to Narragansett Bay. However, with intensifying nitrogen management in estuaries, the need to constrain the rates of pelagic N2 fixation in these systems will be essential for estimating nitrogen fluxes within the bay and to the adjacent coastal ecosystems.
Intervención psicoeducativa dirigida a la comunicación para cuidadores de personas con demencia: una revisión sistemática

Introducción: La demencia es un cuadro de deterioro cognitivo múltiple en el cual las actividades de la vida diaria del paciente se ven comprometidas (Garzón, Méndez y Benito 2011). Debido a estos cambios neurodegenerativos que aparecen con la demencia, estas personas a menudo presentan dificultades para encontrar palabras, producir sonidos, tener una adecuada fluidez o para la comprensión del lenguaje (Allan y Killick, 2014). Por lo tanto, la comunicación entre las personas con demencia y sus cuidadores puede verse afectada, lo que tiene consecuencias sustanciales para su calidad de vida y la de sus cuidados (Alnes, Kirkevold y Skovdahl, 2011). Objetivo: El objetivo de este estudio pretende establecer una actualización de las intervenciones psicoeducativas enfocadas a la comunicación entre cuidadores y personas con demencia. Metodología: Realizamos una revisión sistemática de los últimos 10 años con el fin de detectar los componentes comunicativos presentes en las intervenciones. Resultados: Entre otros resultados, encontramos que la literatura científica enfocada en la psicoeducación de familiares y cuidadores de personas con demencia es amplia pero el abordaje de estrategias comunicativas, si bien se contempla en algunos programas, se aborda tangencialmente. Conclusiones: Concluimos destacando la necesidad de profundizar en este ámbito en posteriores estudios.
Classification of multi-site damage using support vector machines

Pattern recognition is now well-known to be a powerful approach to addressing the higher levels of damage identification e.g. location and severity assessment of damage. However, a major problem in implementation for real structures is the need for training data associated with all possible damage states. Even if appropriate data were available for individual damage states, the combinatorial explosion in states which occurs when multiple simultaneous damages are present would usually prohibit a pattern recognition approach. One approach to the solution of this problem is to construct classifiers on the basis of single damage data which will generalise to multiple damage states; the current paper is a very preliminary step in this direction. In the first part, a comprehensive multiple damage feature database is established as the result of an experimental campaign on a full-sized aircraft wing structure; in the second part, a classifier based on the support vector machine paradigm is investigated. The paper also considers how data visualisation can shed light on which features are likely to generalise best from the single damage problem to the multiple damage case.
BoxCar and shotgun proteomic analyses reveal molecular networks regulated by UBR5 in prostate cancer

Prostate cancer (PC) is a major health and economic problem in industrialized countries, yet our understanding of the molecular mechanisms of PC progression and drug response remains limited. Accumulating evidence showed that certain E3 ubiquitin ligases such as SIAH2, RNF7, and SPOP play important roles in PC development and progression. However, the roles and mechanisms of other E3s in PC progression remain largely unexplored. Through an integration analysis of clinical genomic and transcriptomic profiles of PC tumors, this study identified UBR5 as a top PC‐relevant E3 ubiquitin ligase whose expression levels are strongly associated with PC progression and aggressiveness. BoxCar and shotgun proteomic analyses of control and UBR5‐knockdown PC3 cells complementarily identified 75 UBR5‐regulated proteins. Bioinformatic analysis suggested that the 75 proteins form four molecular networks centered around FANCD2, PAF1, YY1, and LAMB3 via direct protein–protein interactions. Experimental analyses demonstrated that UBR5 associates with and downregulates two key DNA damage repair proteins (XRCC3 and FANCD2) and confers PC cell sensitivity to olaparib, a PARP inhibitor in clinical use for cancer therapy. This study represents the first application of BoxCar in PC research, provides new insights into the molecular functions of UBR5 in PC, and suggests that PC patients with UBR5‐high tumors may potentially benefit from PARP inhibitor treatment.
Non-destructive measurement toolkit for corrosion monitoring and fracture detection of bridge tendons

One of the most considerable challenges of building management is to ensure the integrity and the functionality of prestressed members during service life. But particularly corrosive and mechanical influences on the prestressing steel reinforcement strongly impair the long-term performance and durability of interior as well as of exterior tendons in concrete bridges and of other prestressed structures. The durability state and degradation of tendons can be assessed primarily on the basis of the tendon's force, the corrosion state and the existence of steel fractures. For the determination of these parameters, this paper will briefly report on the application and practical verification of a measurement toolkit, which is used for monitoring, inspecting and testing of prestressed concrete elements, with main consideration of prestressed tendons in bridges. This toolbox comprises conventional inspection and several innovative measurement and monitoring techniques, which have been developed, tested and optimised by the authors in the last decade.
Analysis of River Regime Data Based on the Improved Apriori Algorithm

With the informatization development of water conservancy, the data of water conservancy increased gradually. The data of river regime comes up with the features of real-time and historicity. Therefore, the data has the character of diversity, large and abundant contents. Because of the restrict of the classic Apriori algorithm, many researchers cant meet the requirements of those large data analysis. So, this thesis explained the improvements of the classic Apriori algorithm, designed and elaborated the effectiveness of association rules in river regime resource.
A novel waveguide design for traveling-wave electroabsorption modulators

The overall goal of the current thesis addresses the configuration of the waveguide used in Traveling-wave Optical Modulators. In general, our concerns affiliate mostly with achievement of high confinement factor, improved coupling efficiencies and finally single-mode propagation. In principle, waveguides for optical modulators are quite difficult to design entirely, and the usual, and perhaps the most fruitful, approach is to incorporate or slightly modify one of the existing designs. In this sense, we base our structure on the available waveguide, which was already realized in the department, and introduce two etched channels in either side of the mesa structure. From technological point of view, the mentioned fact guarantees the robustness of the novel waveguide for implementation purposes. Meanwhile, we restrict our modifications in a way not to violate the plausible properties of the available guides rather to enhance them more to meet our further expectations. We show that both confinement factor and coupling efficiency can enhance considerably by virtue of these etched channels. Also, it is shown that the novel design renders single-mode propagation structure.
An Energy‐Efficient, BiFeO3‐Coated Capacitive Switch with Integrated Memory and Demodulation Functions

A capacitive switching behavior is observed in a Si3N4/p‐Si‐based metal–insulator–semiconductor (MIS) structure due to the electron tunneling at the Si3N4/p‐Si interface. A BiFeO3 (BFO) layer is deposited on Si3N4/p‐Si by pulsed laser deposition technique to obtain the memcapacitive effect as the distribution of positive charges in the Si3N4 layer can be stabilized by the polarization charge of the ferroelectric BFO coating layer. The capacitive switching behavior of the Al/BFO/Si3N4/p‐Si/Au MIS structure is also sensitive to both intensity and wavelength of the illumination, which offers the possibility to create a photodetector for both intensity and color detection. Thus, the presented device has the potential application for future information storage and visible light communications. As an example, a photocapacitive demodulator with capability of decoding both wavelength and intensity information of the incident light is demonstrated.
The Costs of Medical Care for Covid-19 Patients: A case study in Turkey

Objective: This study aims to calculate the medical costs of Covid-19 patients for hospitals based on the severity of clinical care. Design: The study was conducted in a hospital in Istanbul/Turkey. A micro-costing approach was performed using historical cost data for one year. All direct and indirect medical inputs were determined in quantities and monetary values for four types of Covid-19 patients in the hospital. Results: The analysis calculated the unit cost of an outpatient to be 459,99 ₺, while the cost per day for inpatient to be 1.184,63 ₺, for non-intubated in intensive care unit to be 1.938,11, for intubated in the intensive unit to be 2.393,99₺. The study also indicates that the total cost of a non-intubated patient in intensive care units is 1,54 times higher than the total cost per inpatient. An intubated patient’s cost is 2,08 times higher than an inpatient’s cost. Conclusion: This study indicates that Covid-19 patients incur significantly high costs for hospitals. The findings of the study provide empirical data for different types of patients which can be used in clinical management and can help all related governing bodies to plan their actions and make the decisions
Low-voltage analog filters

This paper reviews the design of analog filters at low supply voltage. In particular, the main focus is on switched capacitor and g/sub m/-C type filters because, at the present time, they have the greatest commercial importance. SC implementations are discussed in the context of low frequency high precision applications while g/sub m/-C implementations are discussed in the context of high frequency medium/low precision applications. Both fundamental and practical limitations to the achievable dynamic range at low supply voltage are explained. The paper reviews well established circuit and architectural techniques as well as some promising new ones that might result in performance improvements in the future.
Mixtures Created for Artificial Meadow-Pasture Areas According to the Animal Type to Graze and the Effect of Organic Fertilization on Botanical Composition

Meadow and pasture areas are one of the most important natural resources of a country and have a large share in the supply roughage, which is the most important input in animal production (Tutar and Kökten 2019). It also provides benefits in preventing erosion, protecting water resources and biodiversity, maintaining the presence of medicinal plants and wild vegetables (Gökkuş and Koç 2001; Bilgili and Koç 2020). In Turkey, pastures have decreased steadily every year, from 44 million hectares to 14.6 million hectares for nearly six decades (Anonymous 2020). Also, vegetation-covered ratio and botanical composition have decreased in pastures due to the irregular and overgrazing at the same period. This pressure on the pastures and adverse competition conditions lead to the exixting of plants with high forage value and preferred by animals and an increase in invasive species, and also causes erosion risk in sloping areas (Gökkuş and Koç 2001; Palta and Lermi 2019). All these negativities limits the use of our pastureland puts our animal husbandry in an impasse (Gökkuş 2018). For this reason, artificial meadows and pastures are gaining importance in order to meet the feed needs of animals and these
Curcumin Supplementation and Endometrial Lining: Examining the Role and Pathophysiology of Use During Frozen-Thawed Embryo Transfer

Curcumin is a commonly used herbal supplement purported for its antioxidant, anti-inflammatory, and antineoplastic properties. The effects of curcumin supplementation on endometrial lining have been proposed; however, endometrial preparation in the case of frozen-thawed embryo transfer (FET) has not been established. This case series references two scenarios where turmeric was ingested by the patient, and endometrial thickness was subsequently reduced disrupting the FET cycle. Throughout this case series, curcumin's possible interactions with the uterine lining are summarized. Additionally, these cases highlight the importance of physicians’ awareness of taking a full history of any herbal remedies or supplements in addition to prescription or over-the-counter medications taken when undergoing treatment for controlled FET cycles or in-vitro fertilization (IVF). To our knowledge, no studies to date have investigated this relationship.
An Empirical Study of the Relationship between Business Performance Measures and Environmental and Competitive Strategy Variables

This paper aims to investigate the relationship among business strategies and business performance in global and local manufacturing companies. The research is based an International Manufacturing Strategy Survey (IMSS2005) of about 700 companies from more than 20 countries. We first proposed a new method to construct a generic measure of business performance from the available performance measures in IMSS. Based on this new measure we developed a simple discriminant analysis to allocate each entry (company in the IMSS) into a particular category of business performance. Of course we performed some statistical tests to confirm the validity of this classification. We then analysed the contribution (importance) of various environmental and competitive variables to each category of the generic business performance in order to identify the most influential variables and notice of their difference among different business performances. This was done intuitively using graphical analysis, but we also carried out statistical tests to confirm that companies at different performance levels do operate at different environments and pay different attentions to competitive strategies. The models we developed are simple but novel and very practical. The results showed significant differences among business performances in terms of influential variables, and we conclude that this method can also be used to analyse other part of the data from the IMSS.
Review of national financial education policies aimed at the young

Purpose: The paper investigates and synthesizes an in-depth overview of national financial education policies and strategies aimed at the young, highlights the best practices, gives recommendations for the most efficient financial education efforts at the national level and the implementation of an efficient financial education policy in Croatia. Methodology: The analysis is conducted as a case study of financial education policies and strategies aimed at the young of the countries that achieved the best results on the OECD PISA test, Australia, the United States of America and the United Kingdom. Results: The examined countries have national financial education policies with similar aims, fields of financial education and strategies of evaluation but, although they are part of the curriculum, the programs are mostly not standardized and financial education efforts towards teachers and parents are not emphasized. Conclusion: To be efficient, a financial education program aimed at the young has to be relevant, customized according to participants’ characteristics, has to relate knowledge to a specific action, has to be longterm, successfully evaluated, standardized on the national level, implemented at a younger age and have a specified aim. Financial education should be considered as an independent subject in formal education.
The dynamics of a current collection system for an electric locomotive

The motion of an overhead trolley wire, suspended at equal intervals by stiff springs, in response to a pantograph moving with constant speed is analysed. The pantograph is modelled by two discrete masses connected by springs and dampers. Away from the supports the inertia and elasticity of the pantograph can be neglected and a simple solution for the wire and pantograph displacement is obtained. Near a support this solution is not valid as it predicts discontinuities in the vertical pantograph velocity. A different first approximation is then required in which the support elasticity and the pantograph inertia and elasticity must be included. This problem is reduced to that of solving a system of four linear differential equations containing one term with a stretched argument. The numerical and asymptotic solution of such a system is discussed and results are obtained for the contact force and pantograph displacement near a support in typical operating conditions. This disturbance at the support is propagated with the wire wave speed and reflected at the subsequent support, thus interacting with the pantograph again. This interaction is analysed and a uniformly valid solution obtained for the contact force over a complete span. Some conclusions are made about possible operating conditions in which loss of contact between the pantograph and the wire may occur.
A Practical Approach for Security Measure Selection Problem and Its Availability

Recently, information security management in many organizations is carried out based on a Information Security Policy. However, no effective method of selecting the optimum security measures has established yet. Hence, a security measures selection is now greatly dependent on the knowledge/experience of a system designer, and any objective evaluation of appropriateness of the selected security measures is impossible. To cope with the inconvenience, this paper proposes an approach to formulate the problem for selecting security measures. Then, the availability of our method is evaluated by comparing the security measures that our method has selected with the ones that a system designer has chosen.
Is change worth it? The effects of adopting modern agricultural inputs on household welfare in Rwanda

This study investigates the driving factors that influence farmers’ decisions to adopt modern agricultural inputs (MAI) and how this affects farm household welfare in rural Rwanda. To account for heterogeneity in the MAI adoption decision and unobservable farm and household attributes, we estimate an endogenous switching regression (ESR) model. The findings reveal that size of land endowment, access to farm credit and awareness of farm advisory services are the main driving forces behind MAI adoption. The analysis further shows that MAI adoption increases household farm income, farm yield and equivalised consumption per capita. This implies that adopting MAI is the most consistent and potentially best pathway to reduce poverty among rural farmers. The study hence suggests that policymakers should align the effective dissemination of MAI information and farm advisory services, strengthen farm credit systems and improve market access – most crucially at affordable prices – among small-farmers throughout Rwanda.
Comparison of Green, Blue and Infrared Light in Wrist and Forehead Photoplethysmography

In this study we compared LED light sources of three different wavelengths: blue, green and infrared for the use in wrist and forehead photoplethysmography ( PPG ). Criteria for comparison were root mean square ( RMS ), pulsating to stationary tissue component ratio ( AC/DC ) and artifact to signal ratio ( ASR ). Our study showed that the green light is the most suitable for the wrist PPG and an infrared light source is better for the forehead PPG .
An Analysis of Pure-revenue Licensing

This paper analyzes pure-revenue technology licensing, where licensors solely seek the obtaining royalties. Since strategic concerns are left aside, the licensing decision is mainly driven by the features of the innovations. Our aim is to identify such characteristics. We use the NBER Patent Citations Database to explore different dimensions of the patented technologies present in yet2.com, a marketplace likely to capture pure-revenue transactions. Our findings point out that these technologies differ from the mean technology in the licensor's portfolio with respect to importance, innovativeness, scope, complementarity and fit into the firm's core. Results increase our awareness on the drivers of technology licensing decisions.
