Sensory analysis of Ontario Riesling wines from various water status zones
Authors: Willwerth James , Reynolds Andrew , Lesschaeve Isabelle
Published: August 2018

Aims: Determinants of the terroir effect in Riesling were sought by choosing vine water status as a major factor. It was hypothesized that consistent water status zones could be identified within vineyards, and, differences in wine sensory attributes could be related to vine water status.Methods and results: To test our hypothesis, 10 Riesling vineyards representative of each Ontario Vintners Quality Alliance sub-appellation were selected. Vineyards were delineated using global positioning systems and 75 to 80 sentinel vines were geo-referenced within a sampling grid for data collection. During 2005 to 2007, vine water status measurements [leaf water potential (ψ)] were collected bi-weekly from a subset of these sentinel vines. Vines were categorized into “low” and “high” leaf ψ zones within each vineyard through use of geospatial maps and replicate wines were made from each zone. Wines from similar leaf ψ zones had comparable sensory properties ascertained through sorting tasks and multidimensional scaling (2005, 2006). Descriptive analysis further indicated that water status affected wine sensory profiles, and attributes differed for wines from discrete leaf ψ zones. Multivariate analyses associated specific sensory attributes with wines of different leaf ψ zones. Several attributes differed between leaf ψ zones within multiple vineyard sites despite different growing seasons. Wines produced from vines with leaf ψ >-1.0 MPa had highest vegetal aromas whereas those with leaf ψ <-1.3 MPa were highest in honey, petrol and tropical fruit flavors. Vines under mild water deficit had highest honey, mineral, and petrol and lowest vegetal aromas.Conclusion: Results indicate that water status has a profound impact on sensory characteristics of Riesling wines and that there may be a quality threshold for optimum water status.Significance and impact of the study: These data suggest that vine water status has a substantial impact on the sensory properties of Riesling wines. Variability of leaf ψ within vineyards can lead to wines that differ in their sensory profiles. These findings were consistent among vineyards across the Niagara Peninsula. These strong relationships between leaf ψ and sensory attributes of Riesling suggest that vine water status is a major basis for the terroir effect.

Jembatan merupakan suatu prasarana transportasi yang berfungsi untuk menghubungkan dua bagian jalan yang terpisahkan oleh adanya rintangan-rintangan seperti lembah yang dalam, sungai, saluran irigasi, jalan kereta api, waduk, dan lain sebagainya. Seiring dengan bertambahnya populasi manusia, maka semakin meningkat pula kebutuhan akan sarana dan prasarana transportasi. Di Patikraja Kabupaten Banyumas, terdapat jembatan kecil yang melintang di atas Sungai Serayu. Jembatan ini sebelumnya merupakan jembatan kereta api yang dibangun pada era pemerintahan Belanda. Seiring dengan bertambahnya jenis dan jumlah kendaraan bermotor, serta mundurnya perkebunan tebu untuk industri gula, jembatan ini beralih fungsi dari jembatan. Berdasarkan analisis yang telah dilakukan yang mengacu pada Peraturan Perencanaan Teknik Jembatan, Bridge Management System (BMS) oleh Dirjen Bina Marga, SNI-T02-2005 mengenai Pembebanan untuk Jembatan, SNI T03-2005 mengenai Perencanaan Struktur Baja untuk Jembatan, dan SNI 03-2833-2008 mengenai Standar Perencanaan Ketahanan Gempa untuk Jembatan, jembatan Sungai Serayu mempunyai stress ratio maksimum sebesar 1.575 pada penampang memanjang jembatan, dan angka kelangsingan yang cukup tinggi pada ikatan angin rangka jembatan.

Published: August 2018

Pemenuhan kebutuhan terhadap listrik sangat tinggi dan memerlukan jaringan yang mampu menjangkau ke seluruh pelanggan. Jaringan untuk mendistribusikan  listrik ke masyarakat sangat kompleks terdiri dari jaringan bawah tanah dan tiang-tiang serta tower. Bangunan tiang-tiang dan tower-tower tersebut sering menimbulkan masalah dalam pengunaan lahan karena memerlukan tempat yang cukup luas. Masalah penggunaaan lahan ini banyak timbul di daerah perkotaan karena semakin sulitnya lahan yang tidak terpakai dan harga lahan yang mahal. Salah satu lokasi yang mengalami permasalahan adalah di daerah Jalan Gatot Subroto Barat, Denpasar. Permasalahan yang terjadi di daerah ini adalah tower milik PLN yaitu tower SUTT 150 kV no.71 menghalangi jalan masuk ke lahan milik warga, sehingga harus melakukan rekayasa dinding penahan tanah dan pondasi dengan memotong sebagian tanah timbunan serta dinding penahan tanah tanpa mengurangi keamanan konstruksi tower SUTT. Untuk mengatasi masalah tersebut direncanakan suatu dinding penahan tanah dari tiang bor (bored pile) untuk mengganti dinding penahan tanah tipe gravitasi yang telah digunakan sebelumya. Sebelum dilakukan perhitungan perlu dilakukan penyelidikan kondisi tanah dasar di lokasi proyek sehingga dapat direncanakan dinding penahan tanah yang sesuai dan memadai. Setelah melakukan penyelidikan tanah di laboratorium dihasilkan nilai sudut geser tanah (ϕ) = 30º dan berat volume (γ) = 1,6 gr/cm3 dan setelah melakukan analisis pada dinding penahan tanah diperoleh nilai momen maksimum (M maks) = 2384,248 kg.m dan gaya geser maksimum (D maks) =  1098,952 kg.  Hasil perhitungan bahan dinding penahan tanah digunakan beton bertulang dinding susunan bored piled diameter 40 cm dengan kedalaman pancang 4,5 m dari tanah eksisting dan tinggi dinding penahan tanah 3,5 m diatas tanah, sehingga dibutuhkan struktur beton bertulang tiang bor (bored piled) panjang 8 m sebanyak 35 buah. Struktur beton bertulang bored piled diameter 40 cm menggunakan tulangan utama longitudinal 6D16 (6 buah besi ulir  dengan diameter 16 mm) dan tulangan geser menggunakan Ø10-250 (besi polos diameter 10 mm dengan jarak 250 mm).  Luas lahan baru yang didapatkan akibat pengurangan eksisting 10,20 x 13,10 m2 menjadi 5,2 x 6,3 m2, di bagian utara (depan) diperoleh  lahan sebesar 5,0 x 11,7 m2 dan jalan akses di bagian timur dari 2,5 m menjadi 3,9 m.

Cost estimation is the art of estimating the amount of cost required for an activity based on available information. The conceptual cost estimate is an early stage in planning a construction project. This estimate provides the cost that must be budgeted for a construction project. Cost conceptual estimates have low accuracy because the time of calculation and available information is limited. This study aims to obtain a conceptual model of the conceptual cost of short-spaced bridges. The method used is the cost index. The cost index is a figure indicating the cost per m2 of bridges at a given time. The required data are contract documents and drawings design that are built in 2012 - 2015 in Banyumas residency area. Span of bridge 4 - 38.8 meters and width of bridge 2 - 7 meters with caisson  foundation. The data were obtained from Dinas Bina Marga and Public Works Agency. The results showed that the conceptual cost model of reinforced concrete bridge with caisson foundation was BJiL = (100.540.56t2-404.528.636,58t + 406.914.286.088,58) x P x W, with t = year, P = span bridge, and W = bridge width. The error value of validation of this model is 2.31%.

One of the most common mental illnesses, occurring in more than 5 % of the adult population, is depression. In the management of patients with this concomitant pathology in the perioperative period, the anesthesiologist must take into account a number of characteristics. These may be possible difficulties in communication due to patient closure, the risk of developing a “withdrawal syndrome” of antidepressants, side effects, as well as undesirable interactions of these drugs with anesthetics. The article reviews the publications of Russian and foreign articles and manuals on the perioperative management of patients with depression. The characteristics of the main groups of modern drugs for the treatment of depression, the tactics of their withdrawal or continuation of admission before the operation, the features of anesthesia against the background of long-term intake of various groups of antidepressants are presented. The problem of such complication of therapy with these drugs, such as serotonin syndrome, its differential diagnosis is considered. The review also includes non-pharmacological treatments for depression, their complications and anesthesia in electroconvulsive therapy.

Citizen participation and electricity sector governance in Lithuania: current state and future perspectives
Authors: Stasiukynas Andrius , Bileišis Mantas , Smalskys Vainius
Published: August 2018

The paper presents a study, which describes the current governance model of the electricity sector in Lithuania. Electricity and energy production and distribution is highly regulated worldwide. This is also true in Lithuania, where the electricity sector is highly politically prominent, and policy is highly centralized. There are geopolitical concerns towards Russia, which is an important supplier of electricity, and Lithuania’s grid is highly integrated with that of Russia. In addition, Lithuania is a small country dominated by a small number of large state-owned producers and has no regional administrations. Lithuania rhetorically has adopted increased citizen participation as a strategic policy goal. The study investigates how far the rhetorics are followed up by policy planning, implementation, and development of new governance modes. The authors base the study on interviews with 19 experts and regulation analysis. The study found that regulation process is transparent, but this causes lower public interest and consequently lower citizen participation. Existing stakeholder involvement at the policy level is highly arbitrary and favorable to large electricity producers. As production is set to decentralize, this has the potential to overburden the regulatory system and cause conflict between different producers.

In situ upgrade of quantum simulators to universal computers
Authors: Dive Benjamin , Pitchford Alexander , Mintert Florian , Burgarth Daniel
Published: August 2018

Quantum simulators, machines that can replicate the dynamics of quantum systems, are being built as useful devices and are seen as a stepping stone to universal quantum computers. A key difference between the two is that computers have the ability to perform the logic gates that make up algorithms. We propose a method for learning how to construct these gates efficiently by using the simulator to perform optimal control on itself. This bypasses two major problems of purely classical approaches to the control problem: the need to have an accurate model of the system, and a classical computer more powerful than the quantum one to carry out the required simulations. Strong evidence that the scheme scales polynomially in the number of qubits, for systems of up to 9 qubits with Ising interactions, is presented from numerical simulations carried out in different topologies. This suggests that this in situ approach is a practical way of upgrading quantum simulators to computers.

Algorithms for Solving Boundary Value Problems of Deformable Solid Mechanics in View of Creep Strain
Authors: Stankevich I. V. , Volkov S. S.
Published: August 2018

Further development of power and, primarily, engine engineering is associated with significantly increasing specific indicators. For example, the main trend in development of gas turbine engines is to increase gas parameters before the turbine. At the same time, there is an intensive growth of thermal and mechanical tension, and first of all this applies to the parts and components of the flow range. The destruction of these structural elements may have grave consequences. Increasing reliability and durability of responsible components of engines under operating conditions of complex cyclic thermo-mechanical loading is one of the priority tasks of modern engine engineering.

One of the factors to determine a design performance is high-temperature creep. When solving the problems of deformable solid mechanics (DSM) in terms of creep, various options of the theory of hereditary creep and three main technical theories of aging, flow and hardening are widely used. There are also theories known that use an apparatus of the structural models and mechanical analogues to describe the creep. Most theories satisfactorily describe the creep strain under constant or slowly changing loads. Analysis of stress-strain states under variable loads is better described by the theories of flow and hardening, and the theory of hardening has some advantages over the theories of flow, as it gives more exact approximation for experiment results. From the point of view of the computing cycle arrangement, the technical theories have well-known advantages over the hereditary ones.

When using the finite element method (FEM) to solve the boundary value problems of DSM considering the creep strain, an explicit or implicit Euler scheme is very often used. Depending on the features of the problem under consideration, a solution algorithm is constructed either in accordance with the method of initial stress, or by the method of initial strains. The method of initial strains when solving the problems in terms of creep is used more often, because the application of an initial stress method for this class of problems is technically much more complicated. The paper examines the explicit and implicit Euler schemes in combination with FEM. Both schemes are formulated in accordance with the method of initial strains. A constitutive relation was chosen in the form of the theory of flows.
Evolutionary Operators for Global Optimization Population-Based Algorithms. Experience of Systematization
Authors: Karpenko A. P.
Published: August 2018

There are a large number of examples of using the population-based algorithms (P-algorithms) to have a successful solution for complex practical tasks of global optimization, for instance, problems of computer-aided design, synthesis of complex chemical compounds, optimal control of dynamic systems, etc. P-algorithms are also successfully used in multi-criteria optimization, when a preliminary construction of some Pareto set (front) approximation is required. P-algorithms are numerous and very diverse – over 100 such algorithms are known, and new algorithms continue to appear. In this connection, the problem of systematizing expressive means of P-algorithms is of relevance. We consider one of the components of this problem that is the problem of classification of the search operators of P-algorithms.

The paper formulates a global optimization problem and a general scheme of the P-algorithms to solve it. This multilevel classification of the main search operators of P-algorithms at the highest level of the hierarchy identifies the following operators: initialization of the population and the end of the search; coding of individuals; randomization; selection; crossing; population management; local search.

These operators at the next hierarchical level are divided into deterministic and stochastic ones. Further, we distinguish static, dynamic program and dynamic adaptive operators. The following classification levels are "operator dependent", that is, generally speaking, different for each operator. We reveal the essence of these operators and give the use cases in various P-algorithms.

Although the paper uses the names of operators such as selection, crossing, our orientation is not only to evolutionary algorithms. A description scheme of operators presented in this paper can be used to determine any population-based algorithms.

The work development expects extending a set of operators presented, and, above all, using this set and a set of basic essences of population algorithms, the formalization of which was earlier proposed by the author, systematizing the most known algorithms of this class.
Anisotropic Half-Space Temperature Field with its Moving Boundary Being under Local Pulse-periodic Heat Action in Heat Exchange Conditions with External Environment
Authors: Attetkov A. V. , Volkov I. K.
Published: August 2018

A noticeably raising interest in analytical research methods in the mathematical theory of the thermal conductivity of solids [1-3] was initiated by various causes, among which, as the most significant, special mention should go to the widespread practical engineering application of computer technology, mathematical modelling techniques and anisotropic materials of various origin. At present, the "anisotropic section" [3, 4] holds a most unique position in the mathematical theory of the thermal conductivity of solids, due both to the specificity of the mathematical models used in it, and to the fair-minded development need in fundamentally new high-performance and absolutely stable computational methods [4-6] to solve real, practically important engineering tasks.

The spectrum of practical use of solutions to problems of the mathematical theory of the thermal conductivity, presented in an analytically closed form, is quite wide. In particular, such solutions are used to test new computational algorithms, and the problems generating these solutions are called test problems. And if in the traditional sections of the mathematical theory of the thermal conductivity a set of test problems is very extensive [1-3, 7], then test problems of the "anisotropic thermal conductivity" in regions with fixed and moving boundaries are inconsiderable in number [4, 8-14].

The main objective of the research is to solve the problem of determining the temperature field of an anisotropic half-space, the boundary of which moves linearly and is subject to local pulse-periodic thermal action under conditions of heat exchange with the external environment.
Research of New Criteria for Detecting First-order Residuals Autocorrelation in Regression Models
Authors: Bazilevsky M. P.
Published: August 2018

When estimating regression models using the least squares method, one of its prerequisites is the lack of autocorrelation in the regression residuals. The presence of autocorrelation in the residuals makes the least-squares regression estimates to be ineffective, and the standard errors of these estimates to be untenable. Quantitatively, autocorrelation in the residuals of the regression model has traditionally been estimated using the Durbin-Watson statistic, which is the ratio of the sum of the squares of differences of consecutive residual values to the sum of squares of the residuals. Unfortunately, such an analytical form of the Durbin-Watson statistic does not allow it to be integrated, as linear constraints, into the problem of selecting informative regressors, which is, in fact, a mathematical programming problem in the regression model. The task of selecting informative regressors is to extract from the given number of possible regressors a given number of variables based on a certain quality criterion.

The aim of the paper is to develop and study new criteria for detecting first-order autocorrelation in the residuals in regression models that can later be integrated into the problem of selecting informative regressors in the form of linear constraints. To do this, the paper proposes modular autocorrelation statistic for which, using the Gretl package, the ranges of their possible values and limit values were first determined experimentally, depending on the value of the selective coefficient of auto-regression. Then the results obtained were proved by model experiments using the Monte Carlo method. The disadvantage of the proposed modular statistic of adequacy is that their dependencies on the selective coefficient of auto-regression are not even functions. For this, double modular autocorrelation criteria are proposed, which, using special methods, can be used as linear constraints in mathematical programming problems to select informative regressors in regression models.
Mathematical Modeling of the Contact Interaction of Two Elastic Bodies Using the Mortar Method
Authors: Stankevich I. V. , Aronov P. S.
Published: August 2018

The article discusses the development of an algorithm for solving contact problems of elasticity theory. Solving such problems is often associated with necessity of using mismatched grids. Their joining can be carried out both with the help of iterative procedures that form the so-called Schwarz alternating methods, and with the help of the Lagrange multipliers method or the penalty method. The algorithm constructed in the article uses the mortar method for matching the finite elements on the contact line. All these methods of joining the grids make it possible to ensure continuity of displacements and stresses near the contact line. However, one of the main advantages of the mortar method is the possibility of independent choice of different types of finite elements and form functions both on both boundaries of two bodies on the contact line, and when integrating along it. The application of this method in conjunction with the classical formulation of the finite element method based on the minimization of the Lagrange functional leads to a system of linear algebraic equations with a saddle point. The article discusses in detail its numerical solution based on the modified symmetric successive upper relaxation method.

The results of the constructed algorithm are demonstrated on three test contact problems. They analyze the stress-strain state of differently loaded contacting two-dimensional plates. The examples considered show that continuity of the displacements of displacements and stresses is preserved near the contact line. The versatility of the developed algorithm leaves the possibility of further analysis of the effectiveness of the mortar method using different types of finite elements and form functions.
Polynomial Solutions of the Dirichlet Problem for the Tricomi Equation in a Strip
Authors: Algazin O. D.
Published: August 2018

In the paper we consider the Tricomi equation of mixed type. This equation is elliptic in the upper half-plane, hyperbolic in the lower half-plane and parabolically degenerate on the boundary of half-planes. Equations of a mixed type are used in transonic gas dynamics. The Dirichlet problem for an equation of mixed type in a mixed domain is, in general, ill- posed. Many papers has been devoted to the search for conditions for the well-posednes of the Dirichlet problem for a mixed-type equation in a mixed domain.

This paper is devoted to finding exact polynomial solutions of the inhomogeneous Tricomi equation in a strip with a polynomial right-hand side. The Fourier transform method shows that the Dirichlet boundary value problem with polynomial boundary conditions has a polynomial solution. An algorithm for constructing this polynomial solution is given and examples are considered. If the strip lies in the ellipticity region of the equation, then this solution is unique in the class of functions of polynomial growth. If the strip lies in a mixed domain, then the solution of the Dirichlet problem is not unique in the class of functions of polynomial growth, but it is unique in the class of polynomials.

Background

Treatment of patients with ULMCA (unprotected left main coronary artery disease) with percutaneous coronary intervention (PCI) has been compared with coronary artery bypass graft (CABG), without conclusive results.

Methods

All randomized controlled trials (RCTs) and observational studies with multivariate analysis comparing PCI and CABG for ULMCA were included. Major cardiovascular events (MACEs, composite of all-cause death, MI, definite or probable ST, target vessel revascularization and stroke) were the primary end points, whereas its single components were the secondary ones, along with stent thrombosis, graft occlusion and in-hospital death and stroke. Subgroup analyses were performed according to Syntax score.

Results

Six RCTs (4717 patients) and 20 observational studies with multivariate adjustment (14 597 patients) were included. After 5 (3–5.5) years, MACE rate was higher for PCI [odds ratio (OR) 1.10, 95% confidence interval (CI) 1.07–1.14], without difference in death, whereas more relevant risk of MI was because of observational studies. Coronary stenting increased risk of revascularization (OR 1.52; 95% CI 1.34–1.72). At meta-regression, performance of PCI was improved by use of intra-coronary imaging and worsened by first generation stents, whereas two arterial grafts increased benefit of CABG. For patients with Syntax score less than 22, MACE rates did not differ, whereas for higher values, CABG reduced MACE because of lower risk of revascularization. Incidence of graft occlusion was 3.24% (2.25–4.23), whereas 2.13% (1.28–2.98: all CI 95%) of patients experienced stent thrombosis.

Conclusion

Surgical revascularization reduces risk of revascularization for ULMCA patients, especially for those with Syntax score greater than 22, with a higher risk of in-hospital death. Intra-coronary imaging and use of arterial grafts improved performance of revascularization strategies.

Aims: The aim of this study was to asses the platelet activation in the acute phase of ischemic stroke and transient ischemic attack (TIA) by defining p-selectin (CD62) expression by flow cytometry in vivo – without stimulation with agonists. We also studied whether antiplatelet therapy supresses the levels of baseline p-selectin expression and verified if there is a correlation between platelet CD62 expression and the type of ischemic stroke.

Methods: We determined the expression of platelet surface p-selectin using whole-blood flow cytometry within the first 48-hours after onset of cerebral symptoms in patients with atherothrombotic and lacunar ischemic stroke and in healthy volunteers. We studied the realationship between antiplatelet medication and the type of ischemic stroke to baseline p-selectin expression.

Results: Patients with acute cerebral ischemia have an excess of circulating platelets that express p-selectin, compared to healthy volunteers. The difference between average p-selectin expression in the group of healthy volunteers and the group of patients with stroke was statistically significant (p-value < 0,000001). Patients with stroke without antiplatelet medication showed a higher p-selectin expression than patients with antiplatelet medication (ASA, CLP, or ASA and CLP), hovewer, the difference was not statistically significant. There is no relationship between CD62 expression and the type of stroke.

Conclusions: We can conclude that p-selectin is a highly sensitive blood biomarker of increased platelet activation. Antiplatelet therapy suppresses baseline p-selectin expression only minimally, insignificantly according to our results.
