Background

To better understand the relation between sleep problems and CKD, we examined temporal trends in the prevalence of self-reported sleep problems in adults in the United States and their associations with CKD and all-cause mortality.

Methods

Using data from 27,365 adult participants in five biannual National Health and Examination Surveys (2005–2006 through 2013–2014), we studied five self-reported sleep problems—trouble sleeping, sleep disorder, nocturia (urinating ≥2 times/night), inadequate sleep (<7 hours/night), and excessive sleep (>9 hours/night)—plus a composite index. We conducted three types of analysis: temporal trends in the prevalence of each sleep measure by CKD status, using model-based standardization; cross-sectional analysis of associations between four CKD measures and each sleep measure, using logistic regression; and survival analysis of the association between each sleep measure and mortality, using Cox regression.

Results

The prevalence of trouble sleeping and sleep disorder increased over the five surveys by 4% and 3%, respectively, whereas the other sleep problems remained relatively stable. All sleep problems, except inadequate sleep, were more common during the study period among adults with CKD than without CKD (40% versus 21% for nocturia; 5% versus 2% for excessive sleep; 30% versus 25% for trouble sleeping; 12% versus 8% for sleep disorder). Both eGFR <30 ml/min per 1.73 m2 and albuminuria were positively associated with nocturia and excessive sleep. Excessive sleep and nocturia were also associated with higher mortality (adjusted hazard ratio for >9 versus 7–9 hours/night=1.7; 95% CI, 1.3 to 2.1; and for nocturia=1.2; 95% CI, 1.1 to 1.4).

Conclusions

The high prevalence of sleep problems among persons with CKD and their associations with mortality suggest their potential importance to clinical practice. Future work could examine the health effects of identifying and treating sleep problems in patients with CKD.
Shallow groundwater quality in Latvia and Denmark
Authors: Gosk Edmund , Levins Igors , Flindt Jørgensen Lisbeth
Published: May 2020

Experience and results from the Danish groundwater monitoring programme that has been carried out systematically since 1990, have been used in a co-operative project between Latvia and Denmark. The main objective of the project was to obtain more detailed knowledge of the shallow Latvian groundwater, to optimise the Latvian groundwater monitoring programme and to support the implementation of European legislation such as the Water Framework Directive, the Nitrate Directive and the Groundwater Directive in Latvia. Comprehensive summaries describing the methodology of groundwater quality monitoring as well as the major results from the Danish groundwater monitoring network can be found in GEUS (2005) and Stockmarr (2005). Until recently only few data on Latvian groundwater quality were available, but in a project running from 2003 to 2006, 800 samples from groundwater, springs and drains have been analysed for a large number of components resulting in a comprehensive overview of the status of Latvian groundwater (Fig. 1; Gosk et al. 2006). The project Agricultural influence on groundwater in Latvia was carried out by the State Geological Survey of Latvia and the Geological Survey of Denmark and Greenland (GEUS) and was supported by the Danish Environmental Protection Agency within the framework of the DANCEE programme (Danish Co-operation for Environment in Eastern Europe). As a spin-off of the project this paper compares groundwater quality in the two countries.

Published: May 2020

Following the proposal of the offshore Anholt wind-farm project with an energy capacity of 400 megawatt in the Kattegat, southern Scandinavia, an evaluation of the geotechnical properties of the subsurface of the area is required. As a first step to map the seabed geology the Geological Survey of Denmark and Greenland (GEUS) conducted a geophysical survey (Leth et al. 2009) which, together with cone penetration tests and data from boreholes, lead to a greater understanding of the geological architecture and development of the 144 km2 survey area (Figs 1, 2).
Recent changes in the nutrient status of a soft-water Lobelia lake, Hampen Sø, Denmark

Published: May 2020

Nutrient-poor, low-productive (oligotrophic) soft-water lakes in the Atlantic areas of West and North-West Europe – the so-called Lobelia lakes – are of high conservation value as their low nutrient status favours a particular submerged macrophyte flora with isoetids, which are becoming increasingly rare or threatened due to nutrient enrichment (eutrophication) associated with landuse changes and urbanisation. European Union member states have a duty of care, under the Habitats Directive, to protect the biodiversity of oligotrophic to mesotrophic (moderately productive) standing waters.
Characterisation of host rocks and hydrothermal alteration of the Qussuk gold occurrence, southern West Greenland
Authors: Schlatter Denis Martin , Christensen Rasmus
Published: May 2020

Gold exploration in the Godthåbsfjord region has been carried out since the early 1990s, and the region is now recognised as a gold province. Several prospects have been drilled and Storø is the most advanced project in the Færingehavn terrane. The gold occurrence at Storø is 2635 Ma old according to 207Pb/206Pb age determinations of metamorphic zircons associated with auriferous arsenopyrite (Nutman et al. 2007). Qussuk is located in the Akia terrane (Fig. 1), separated from the Færingehavn terrane in the south by the SW–NE-trending Ivinnguit fault. The Ivinnguit and Ataneq faults are spatially associated with several hydrothermal gold occurrences. From north to south these are: Isua, Storø, Bjørneøen, Sadelø, Store Malene and Qilanngaarsuit (Fig. 1; Appel et al. 2005; Kolb et al. 2009). The Qussuk prospect 20–25 km north of the Ataneq fault is 20 km long, 2–3 km wide, and divided from north to south into the ‘Swan N’, ‘Swan’ and ‘Plateau’ areas (Fig. 1).

A number of sedimentary basins of various ages are located onand offshore Vietnam (Fig. 1). Some of them have significant petroleum resources and have thus attracted interest from industry and academia (Rangin et al. 1995; Matthews et al. 1997; Lee & Watkins 1998; Lee et al. 2001). Moreover, Vietnam is located in a position central to the understanding of the geological development of South-East Asia (Hall & Morley 2004). The structural style and the stratigraphy of the Vietnamese basins thus provide a valuable record about the development of South-East Asia throughout the Phanerozoic and the subsequent Eocene as well as younger deformation associated with the collision and indentation of India into Eurasia and the opening of the South China Sea (Fyhn et al. 2009a, 2010a).
On Certain Problems of Identification of Thermal Density of the Temperature State of the Hollow Cylinder Shell
Authors: Aralova Albina
Published: May 2020

Introduction. In conditions of the active use of composite materials, as when accomplishing the tasks of extending the service life of existing structures, problems on recovering unknown parameters of their components under the known data on their surface arise. In [1-4], to solve the problems of identification ofparameters of a wide range, it is proposed to construct explicit expressions of the gradients of residual functionals by means of the corresponding conjugate problems obtained from the theory of optimal control of the states of multicomponent distributed systems, which is the development of the corresponding researches of Zh. Lyons. In [5-7], this technology is extended to the problem of thermoelastic deformation of multicomponent bodies.

In this article some problems of optimal control of the temperature state of a cylindrical body with a cavity are considered.

The purpose of the paper is to show the algorithm for identifying the parameters of a cylindrical hollow shell, based on the theory of optimal control and using the gradient methods of Alifanov.

Results. Based on the theory of optimal control, the temperature control of a cylindrical shell is studied. To solve the problem of identifying the parameters of a hollow cylindrical shell, namely, finding the heat flux powers on its surfaces, based on [1,2,5-7], a direct and conjugate problem and gradients of non-viscous functionals are constructed. Discretization by the finite element method using piecewise quadratic functions is carried out and accuracy estimates for it are presented. The initial problem in the model examples presented is solved using gradient methods, where at each step of determining the (n + 1) the approximation of the solution, the direct and adjoint problems are solved using finite element method with the help piecewise quadratic functions by minimizing the corresponding energy functional.

A number of model examples solved.
Constructing the Approximate Solution of Axisymmetric Problem on the Dynamics of Anisothermal Moisture Transfer
Authors: Marchenko Olga , Samoilenko Tetiana
Published: May 2020

Introduction. Calculation of dynamics of the anisothermal moisture transfer processes in axisymmetric formulation is essential in the study of wet soils condition around, for example, vertical drains, wells, piles, etc. In this paper, we formulate the initial boundary value problem for the system of moisture and heat transfer nonstationary equations. The problem is considered for isotropic medium in cylindrical coordinate system under the inhomogeneous mixed boundary conditions. The obtained results are important for future research in cylindrical coordinates of problems that model the migration of moisture during the seasonal freezing of the soil, taking into account phase transitions from unfrozen water to ice in the entire volume of the soil mass without highlighting the crystallization front. In this case moisture exchange and heat transfer characteristics appear as functions of the total humidity. Consequently, the equation of moisture transfer is written relative to the "fictitious" moisture content. Because of the main direction of moisture migration relative to the freezing/melting front, the convective heat transfer along the vertical coordinate axis is considered to be essential that leads to sufficient coincidence with the experimental data. The purpose of the paper is to formulate the appropriate generalized problem in the Galorkin form for the axisymmetric initial-boundary value problem. The important goal is to investigate the accuracy of the continuous in time and completely discrete approximate generalized solutions based on the finite elements method. Results. The algorithm for constructing of approximate generalized solution of the axisymmetric initial-boundary value problem for the system of filtration and heat transfer equations is proposed. The estimates of the convergence rate for the continuous in time and discrete approximate solutions based on the finite elements method are obtained.
Metrological Support for Wireless Sensor Systems
Authors: Kondratov V.
Published: May 2020

The paper identifies twelve problems of metrological reliability of wireless sensor systems that require their solution.

The most urgent is the problem of determining the main parameters of the metrological reliability of wireless sensor systems. It is closely related to solving the problem of self-calibration of optical smart sensors that are part of the smart nodes of the system.

The task of self-calibration of smart sensors is solved when three basic conditions are met: 1) when creating and using structurally redundant optical sensors designed to implement methods of redundant measurements; 2) when developing LEDs or other highly stable sources of optical radiation, including those with controlled parameters, for any given spectral range of wavelengths; 3) when creating in micro-performance filters on a priori given range of the spectrum of optical sines.

The article describes two methods of metrological support for BSS smart sensors, based on the introduction of information redundancy by conducting three clock cycles of measuring physical quantity with a smart sensor, followed by processing the data using an a priori derived algorithm. The disadvantages and advantages of the methods are shown.

It is stated that the use of the theory of excess measurements is the only correct way to solve the problem of self-calibration of sensors and measuring instruments.

Given the harsh operating conditions of optical smart sensors, it is preferable to manufacture them using high technology.

Today, in Ukraine, no one is engaged in a practical solution to the problems of metrological reliability of wireless sensor systems and the solution of the problems of self-calibration of smart sensors.

SUPEROKSIDA DISMUTASE (SOD) DAN RADIKAL BEBAS
Authors: Simanjuntak Evirosa Juliartha , Zulham Zulham
Published: May 2020

Superoxide dismutase (SOD) is an endogenous antioxidant that works by regulating ROS levels. This group of enzymes functions to catalyze the efficient disposal of superoxide anions. Superoxide anions are produced enzymatically and non-enzymatically. In mammals there are 3 types of SOD, namely SOD1 (CuZnSOD), SOD2 (MnSOD), SOD3 (ECSOD). Oxidative stress caused by free radicals has been reported to be involved in several diseases. Various stressors trigger ROS production, also triggering the production of enzymatic antioxidants such as catalase (CAT), hydroperoxidase (HPx) and superoxide dismutase (SOD). Free radicals cause oxidative stress when the amount in the body is excessive, this situation will cause oxidative damage at the cellular, tissue to organ levels that will accelerate the aging process and the onset of disease. Free radicals are molecules that have one or more unpaired electrons and are therefore relatively unstable. Free radicals try to stabilize themselves by taking electrons from other molecules and will produce reactive oxygen species (ROS). If there is a disturbance in the balance of ROS products with antioxidants, oxidative stress will occur which results in damage to cell components. The higher levels of oxidative stress will increase the lipid peroxidation marker which is presented as malondialdehyde (MDA) and decrease the SOD enzyme activity. Thus the role of molecules that have antioxidant activity is very necessary to ward off oxidative stress.

Constructing and Evaluating a Validation Argument for a Next-Generation Alternate Assessment
Authors: Clark Amy K. , Karvonen Meagan
Published: May 2020

Alternate assessments based on alternate achievement standards (AA-AAS) have historically lacked broad validity evidence and an overall evaluation of the extent to which evidence supports intended uses of results. An expanding body of validation literature, the funding of two AA-AAS consortia, and advances in computer-based assessment have supported improvements in AA-AAS validation. This paper describes the validation approach used with the Dynamic Learning Maps® alternate assessment system, including development of the theory of action, claims, and interpretive argument; examples of evidence collected; and evaluation of the evidence in light of the maturity of the assessment system. We focus especially on claims and sources of evidence unique to AA-AAS and especially the Dynamic Learning Maps system design. We synthesize the evidence to evaluate the degree to which it supports the intended uses of assessment results for the targeted population. Considerations are presented for subsequent data collection efforts.

Published: May 2020

This work designed a 2BDE-2 type millet fine and small-amount electric seeder to solve certain problems, such as difficult cultivation and large workload of millet in hilly and mountainous areas. This seeder can finish the sowing operations, such as ditching, fine and small-amount of seed discharging, covering soil and suppressing at one time. The central composite design method was used to test the seeding performance of the seeder along with the factors of the seed metering plate amplitude and operating speed. This task was undertaken to determine the optimal working parameters of the seeder. The mathematical model of the average number of seeds in each 100 mm section and the variation coefficient of seeding uniformity were established. The influence of single factor effects and interaction on the seeding performance was also analysed. The optimum combination after parameter optimisation was determined as follows: seed metering plate amplitude of 109 μm and seeder operating speed of 0.76 m/s. The field sowing experiment was conducted according to the parameter combination. Results showed that the average number of seeds in each 100 mm section was 7.8, and the variation coefficient of seeding uniformity was 19.64%. The relative errors with the predicted values were 1.28% and 4.98%. The research can be used for sowing a small amount of millet in the hilly mountain area.

Published: May 2020

The objective of this paper is to present the efficiency of the separation process on a sieve with a conical separation surface, with a vertical shaft and having vibrational motion. Separation intensity curves of rape seeds through circular sieve apertures were drawn by regression analysis of the quantities of material separated at different distances from the central axis of the sieve, using the Gaussian distribution law. The coefficients of the regression equation and the correlation coefficient of the distribution function with experimental data show a high degree of correlation between them. The movement of the material on the sieve and the separation process, in general, was assessed by the position of the distribution curve maximum, depending on the material flow rate.

Now the engine mini-tiller has become indispensable agricultural machinery in vast hilly and mountainous areas of Southwest China. Many researches have been made to improve its operating comfort, but little effects have been obtained. As an alternative, a new type of electric mini-tiller was developed. For further improvement of its operating comfort, simulation analysis and field test were integrated to decrease the vertical force and vibration RMS values at the handle. The results showed that when the position of centre of gravity moved 19.78 cm, the vertical force was reduced from 154.24 N to 0 N, and vibration RMS values decreased by 20.16% under working condition.
Transnational Corporations as a Source of Career and Biographical Stabilisation: The Case of Polish Corporate Employees
Authors: Gońda Marcin
Published: May 2020

This paper discusses contemporary transformations in the way work is organised and the consequences for the stability of careers and biographies. It debates the widely held belief that organised and predictable life-course paths (including professional careers) have ceased to exist and that work itself has lost its stabilising quality. Biographical data collected among Polish employees of transnational corporations within the project “Poles in the World of Late Capitalism” proves that even though transnational corporations are widely criticised for propelling neoliberal tendencies in the global economy, they provide a means of protecting their employees against today’s uncertainty and occupational risk. Three empirical cases are presented to show how work in a transnational corporation may contribute to achieving and maintaining stability for persons who have had troublesome experiences of working in other sectors of the labour market.
Mathematical models and meanings by school and university students in a modelling task
Authors: Carreira Susana , Baioa Ana Margarida , Werle de Almeida Lourdes Maria
Published: May 2020

This study involves two classes from different educational levels, namely 9th grade and university. Students in both contexts were given a modelling task that required the development of a hand biometrics recognition system, during which they performed experimentation and simulation. As aims of the study, we look for distinctions and commonalities between the models developed in the two classes and seek to know how simulation and experimentation influence students’ production of meaning. The theoretical framework comprises the relationship between the modelling process and the prototyping process and adopts Peirce’s pragmatic perspective on meaning. The research is of a qualitative nature, assuming the characteristics of a case study. The results reveal many commonalities between the modelling in the two contexts. Moreover, experimentation and simulation were relevant elements for the production of meaning by the students, which is endorsed by a pragmatic perspective on meaning
Probleme deschise de fenomenologia lui Husserl prin prisma integrării sale în modelul ontologic informaţional propus de Mihai Drăgănescu
Authors: Manolescu Gorun
Published: May 2020

Abstract: May another reality exist so as to generate our physical world? Both Mihai Drăgănescu and Edmund Husserl said yes. But there is a main difference between those two approaches. So, Romanian scholar Mihai Drăgănescu proposed an ontological model with strong phenomenological character in which information and material principles are at the same level. Instead Husserl proposed an idealist (transcendental) solution. In this respect Drăgănescu’s model seems to be more general and consistent. Also Mihai Drăgănescu says that Husserl’s Phenomenology can be integrated in his model. But for this some problems appeared. Our present work is dedicated to identifying such problems. In subsequent material we will analyze how these problems can be solved.
Cătălina Iliescu-Gheorghiu: a polysystemic model for the comparative analysis of drama from the perspective of descriptive translation studies
Authors: Arhire Mona
Published: May 2020

This review presents a recently published book authored by Cătălina Iliescu Gheorghiu, an academic actively involved in Romanian studies and a translator of Romanian literature. As the title suggests, it is a study that falls under the scope of Descriptive Translation Studies implying the polysystemic model posited by Lambert and Van Gorp for the comparative analysis of drama. The corpus under scrutiny is made up utterances extracted from the play A treia țeapă (The Third Stake) by Marin Sorescu and the corresponding utterances from two of its translations into English. The analytical part is backed up by a solid theoretical framework with its latter section lending the overall structure of the analysis. The categories subject to investigation are (i) preliminary data, (ii) the macro-level structures, (iii) the micro-level structures and (iv) the systemic context. The methodology experimented with drama translation and the findings deriving from it have proved their validity and are valuable input for other similar and possibly more comprising research that can use these findings as hypotheses to be tested further.

”The Summer when my Mother had Green Eyes” is Moldovan writer Tatiana Țîbuleac’s first novel and it was praised by both readers and critics. We examine the Spanish version of this novel, which was published in 2019 by Madrid-based publishing house Impedimenta and has reached its fifth edition in less than a year. The design of this novel alternates short chapters and micro chapters consisting of a sole phrase, as well as sarcastic and poetic tonalities, and reconstructs the narrator's relationship with his dying mother during the last summer they spend together in a French village close to the ocean.
A community of spoken words. Forms and practices of the conversation at Viața românească cenacle
Authors: Munteanu Maricica
Published: May 2020

The present article analyses the conversation of the cenacle Viața românească by exploring three directions of research. In the first place, the study concentrates on the conversation as a phenomenon of loss, focussing on the voice of the writers and oral speech as signs of extreme fragility. On the one hand, the reflection on the absence of the spoken word articulates an imaginary of evanescence that functions as a collective representation of the community. On the other hand, it reconsiders the relation between the oral and the written word by favouring the conversation against the literary work. In the second place, the article investigates the forms of the conversation specific to the cenacle as they appear in the memoirs of some members. Representing the cenacle as a democratic society where each member has equal rights, the memoirs of the cenacle depict, at the same time, some regulations that limit the speech such as the anti-rhetoric, the delicacy, and the admiration. Finally, the last issue to be approached is the content of the conversation. On the one hand, the cenacle represents itself as an elevated group that discusses the issues of literature, investing in the “profitable” conversation (Glinoer, Laisney) at the expense of the agreeable interaction. On the other hand, the cenacle values the forms of entertainment as a way of detachment from writing, the study focussing, in the last part, on the functions of laughter inside the literary community.
Francis Bacon, Jan Baptist Van Helmont and Demetrius Cantemir. Family resemblances of auctoritas in Early Modern Europe
Authors: Ciutacu Sorin

The present paper stakes out the destiny of certain ideas on scientific methods and epistemic and ontological representations that spread in 17th century Europe like a cultural epidemiology of representations against a deist, theosophical, empiricist and occult maze-like background. Our intellectual history study evaluates the family resemblances of auctoritas of three polymaths: Francis Bacon, Jan Baptist Van Helmont and Demetrius Cantemir along the cultural corridors of knowledge. If Francis Bacon was a theoretical founder of doctrines and Jan Baptist Van Helmont was a complex experimenting spirit, Demetrius Cantemir was an able disseminator of philosophy in South Eastern Europe and a creative synthetic spirit bridging the Divan ideas of Western and Eastern minds caught up in the busy exchange of ideas of the Republic of Letters.

The technology should meet the lifestyle need of people and livelihood in a sustainable manner. In the regime of LPG financial system, knowledge has come out as main dynamic strength: advantage in competition of market, household manufacture structure, growth in living standards of living of people, cross border trade opportunity (ADB, 1995). This expertise associated growth has augmented the requirement for power and release of gases. For developing countries, situation is very serious as they are adopting various process of economic development to come up to the level of developed country. As there is impact on environment, there is also a need for other technologies that helps in solving the problem (IPCC, 2000). Sustainability issue and technology diffusion both are divided. The expertise dispersion method requires being a uniform in words of increase, longevity, as well as replication. Also diffused technology should promote sustainable development in meeting the needs of all and causes minimum damage to the environment. This research paper talks about the technology acceptance model which is sustainable. The sustainable energy technology is viewed as portfolio of technologies which uses renewable power possessions for manufacturing up to date power mover; use these power mover properly; elevated value & consistent; cost effectively; to fulfil the requirements of unreachable persons.

The key step of drug discovery is the identification of interaction between drug and target proteins. This isn't just valuable to understand the disease, but also assist to distinguishing antagonistic symptoms of drugs. So, in drug repurposing [3] field the drug-target interaction (DTI) prediction is an essential tool. There are various methods to decipher unknown drug-target interaction [2], this is helped in the area of identifying the lead compound in the drug for a specific disease. In this paper proposes drug-target interaction extraction using Bayesian Personalized Ranking (BPR) method [5]. Here it is also solving the ranking problem by the implementation of matrix factorization method [5]. The proposed procedure can manage the occasion of new drugs and takes compound and hereditary resemblances of meds and targets and target tendency into account. [4].

The current use of social media has created incomparable amounts of social data, as it is a cheap and popular information sharing communication platform. Nowadays, a huge percentage of people depend on the accessible material on social networking in their choices (e.g. comments and suggestions about a subject or product). This feature on exchanging knowledge with a wide number of users has quickly prompted social spammers to exploit the network of confidence to distribute spam messages and support personal forums, advertising, phishing, scams and so on. Identifying these spammers and spam material is a hot subject of study, and while large amounts of experiments have recently been conducted to this end, so far the methodologies are only barely able to identify spam feedback, and none of them demonstrates the value of each derived function type. In this study, we have suggested a machine learning-based spam detection system that determines whether or not a specific message in the dataset is spam using a set of machine learning algorithms. Four main features have been used; including user-behavioral, user-linguistic, review-behavioral and review-linguistic, to improve the spam detection process and to gather reliable data.

Quadratic boost converters in Switched reluctance motor will enhance the output of the motor in the ratio 1:2 thereby making it more efficient. SRM is generally used in heavy ships and aviation which will help to reduce the emission of CO2 through combustion engines. The proposed model will have reduced switching losses with increased output power. In this paper the authors have proposed the idea of simulation of the existing circuit diagram of the SRM drive open loop system, QBC with SRM drive open loop system. Apart from this, the simulation of QBC with SRM drive closed loop PI controller and QBC with SRM drive closed loop FLC controller will be simulated and their voltage output, speed, torque and power will be compared. The proposed system will help us to compare the output of the existing model and the proposed model in terms of rise time, peak time, settling time etc.
