description:  Molybdenum Disulfide, MoS2, layers among two dimensional atomic family structures shows potential use for application in photovoltaic devices. However, their absorption intensity and wavelength range need improvement. In this paper, to increase the absorption intensity with flat top absorption profile, the MoS2 monolayer is inserted in S4 Fibonacci quasi photonic crystal together with other dielectric layers, e.g. Si and SiO2. We found that the S4 thickness will differ for designing of the structure based on either of resonance peaks of MoS2 monolayer. Based on three resonance peaks of MoS2, three structures designed for S4 and their absorption for normal incidence based on transfer matrix method are calculated. Finally, S4 Fibonacci structure with 609 nm of designed wavelength and 12 times periodicity demonstrates giant absorption above 90% with flat top profile between 605 and 665 nm as the best achievement.

description: The quantum search algorithm is a technique for searching N possibilities in only sqrt(N) steps. Although the algorithm itself is widely known, not so well known is the series of steps that first led to it, these are quite different from any of the generally known forms of the algorithm. This paper describes these steps, which start by discretizing Schrödinger's equation. This paper also provides a self-contained introduction to the quantum search algorithm from a new perspective.

description: In the present work, a simple and sensitive cyclic voltammetry, differential pulse voltammetry, and chronoamperometry (CA) glucose sensor was developed at multiwalled carbon nanotubes and tetracinnamide cobalt (II) phthalocyanine (MWCNT-CoTCIDPc) modified GCE. The novel synthesized catalyst confirmed with various spectroscopic techniques. The modified CoTCIDPc/GCE using MWCNTs showed a high electrocatalytic activity and lower potential towards the oxidation of glucose (GOx). The response of GOx was linear over the concentration ranging from (CV 2 - 20; DPV 2 - 12; CA 5 - 50 mM/L), sensitivity for (CV 1.905; DPV 3.483; CA 1.035 mA mM-1 cm-2) and detection limit for (CV 0.9; DPV 5.33; CA 6 mM) (S/N=3). The CVs and DPV techniques display shows the same peak potential (+250 mV). The amperometry response time of the sensor was found as 2 s, the fabricated sensor also exhibited its good selectivity in the presence of common interfering biological species for AA, DA, and UA; besides, the fabricated sensor exhibited its special advantages such as low working potential, sensitivity along with good repeatability and reproducibility for the determination of GOx.

description: Two-dimensionam transition-metal dichalcogenides (TMDC) layers with direct bandgaps have made a new horizon for pplication in photonics and electroptics. The presence of bandgap causes a significant absorption useful in photovoltaic devices. When these layers are located on a substrate that leads to a frequent optical reflection thus affect the absorption.Typically, SiO2 or Si or their combination as a substrate is used for these monolayers. In this paper, we used a transfer matrix method to study the absorption spectra of TMDC monolayers including MoSe2, WSe2, MoS2 and WS2 with the presence of SiO2/ Si substrate with different thicknesses of SiO2 layer. We found that using the SiO2 layer with a thickness of 90 nm in SiO2/ Si substrate does not change the general behavior of absorption and increases the absorption in some regions of the wavelength range.

description: Aluminium alloys are difficult to be manufactured by directed energy deposition (DED) with the widely used infrared laser because of the low absorptivity. A blue laser with a 450 nm wavelength has a significantly higher laser absorptivity in processing aluminium. Here, we developed a 2000 W blue laser directed energy deposition (BL-DED) system for additive manufacturing. In this system, a coaxial camera, a paraxial high-speed camera, and a paraxial infrared camera were simultaneously adopted to analyze the formation and evolution of molten pool characteristics. The relationships among the molten pool characteristics, depositing states, and appearance defects were built. We successfully printed the curved thin wall with good appearance quality by the manual in-situ control of appearance defects. This work demonstrated the advantages of the blue laser in DED of aluminium alloy, which could melt the powders under lower energy input conditions and result in a more stable deposition process.
Non-linearly stable reduced-order models for incompressible flow with energy-conserving finite volume methods

description: A novel reduced-order model (ROM) formulation for incompressible flows is presented with the key property that it exhibits non-linearly stability, independent of the mesh (of the full order model), the time step, the viscosity, and the number of modes. The two essential elements to non-linear stability are: (1) first discretise the full order model, and then project the discretised equations, and (2) use spatial and temporal discretisation schemes for the full order model that are globally energy-conserving (in the limit of vanishing viscosity). For this purpose, as full order model a staggered-grid finite volume method in conjunction with an implicit Runge-Kutta method is employed. In addition, a constrained singular value decomposition is employed which enforces global momentum conservation. The resulting `velocity-only' ROM is thus globally conserving mass, momentum and kinetic energy. For non-homogeneous boundary conditions, a (one-time) Poisson equation is solved that accounts for the boundary contribution. The stability of the proposed ROM is demonstrated in several test cases. Furthermore, it is shown that explicit Runge-Kutta methods can be used as a practical alternative to implicit time integration at a slight loss in energy conservation.

Towards a unified theory of Chiari Malformations
Creators: name: Bartoli, Andréa
Publisher: name: Université de Genève
Year: 2025
Subjects: info:eu-repo/classification/ddc/616.8

description:
More than a century has elapsed since the first case of ectopia of the cerebellar tonsils through the foramen magnum was described by Hans Chiari (1891) and became known as Chiari Malformation. In the following decades a considerable bulk of clinical research was published on similar conditions along with its variants, giving rise to an entire spectrum of Chiari Malformations with changing definitions over time.

Further research in the last decades has then focused on more pre-clinical data, such as the embryology of the posterior fossa and its genetics determinants, or the mathematical modelling of cerebrospinal fluid (CSF) dynamic across the foramen magnum as well as the best radiological assessment for such a condition. Even more recent works mainly from western countries have used large population-based data as well as pooled analysis on multiple epidemiological studies to look at sociodemographic determinants of Chiari malformations.

It is now clear that the simple ectopia of the cerebellar tonsils and its variants reflect different conditions with different explanations and mechanisms so that some authors have provocatively suggested that Chiari Malformation does not exist as such, and that when facing an ectopia of the cerebellar tonsils we should look at any possible explanation leading to such a condition, and only then look for the right treatment.

Following a “reductionist approach”, that is to say looking at small simple elements of a complex problem, current concepts about the ectopia of cerebellar tonsils can be reduced to three main explanations: posterior fossa disproportion (from mesodermal origin), CSF impairment between cranial and spinal compartments and craniovertebral junction instability.

This framework can account for the heterogenous clinical scenarios observed (from completely asymptomatic to multiple neurological and spinal complaints) as well as for various radiological findings encountered not only in the posterior fossa but also in the cranial compartment (e.g. ventricular abnormalities, dural venous changes, cranial vault malformations, etc.) and in the spinal compartment (e.g. craniovertebral junction abnormalities, thoracolumbar deformities, syringomyelia, tethered cord and dysraphisms, etc.). Finally, this heterogeneous model can account for different surgical options and why sometimes they fail and sometimes succeed.

If we do accept the challenge that Chiari Malformation as such does not exist, we can state that such a framework can constitute a unified practical theory to explain the ectopia of cerebellar tonsils: the choice of the nomenclature then becomes a pure semantic matter.

Bronchiolitis
Family-centered care

Integrative medicine

description: Introduction: Bronchiolitis is the leading cause of lower respiratory infections in infants, particularly those under one year old. Despite decades of extensive research on this condition, current management strategies primarily emphasize supportive care. While these measures are essential, they are inherently limited as they focus solely on the immediate needs of the child without addressing the broader implications of the disease. This creates a significant gap in managing the wider impacts and consequences of Bronchiolitis. Aim: this narrative review aims to provide a comprehensive exploration of the psychological, emotional, social, and economic impacts of Bronchiolitis hospitalization on infants, parents, and families, as well as the short- and long-term health consequences for the infant. The ultimate objective is to contribute to the development of family-centered care models that account for the holistic needs of patients and their families. Such an approach allows healthcare providers to go beyond physical treatment, supporting the emotional and psychological well-being of the entire family. The review also seeks to summarize current knowledge, identify emerging trends, and highlight gaps in the existing literature. Methods: A literature search was conducted using PubMed, Embase, and PsycINFO from their inception to the end of August 2024. Studies were selected based on predefined criteria, and data were analyzed using a narrative synthesis approach. Results: The findings indicate that Bronchiolitis significantly impairs the quality of life in infants, particularly in premature infants and those requiring ventilatory support, with persistent effects on feeding, sleep, and behavior lasting long after hospitalization. Parents often experience substantial emotional distress, including anxiety, guilt, depression, and symptoms of post-traumatic stress disorder, which can persist beyond their child's discharge. Family dynamics are also profoundly affected, with daily routines disrupted and financial strain emerging as a significant concern. Conclusions: Bronchiolitis hospitalization has profound and lasting effects on both infants, parents, and their families, reaching beyond immediate health issues to encompass significant psychological, emotional, and economic challenges. Addressing these impacts requires a comprehensive, family-centered approach that includes enhanced support services and strengthened communication strategies.
Narrow Spectral Feature In Resonance Fluorescence With A Single Monochromatic Laser Field

description: We describe the resonance fluorescence spectrum of an atomic three-level system where two of the states are coupled by a single monochromatic laser field. The influence of the third energy level, which interacts with the two laser-coupled states only via radiative decays, is studied in detail. For a suitable choice of parameters, this system gives rise to a very narrow structure at the laser frequency in the fluorescence spectrum which is not present in the spectrum of a two-level atom. We find those parameter ranges by a numerical analysis and use the results to derive analytical expressions for the additional narrow peak. We also derive an exact expression for the peak intensity under the assumption that a random telegraph model is applicable to the system. This model and a simple spring model are then used to describe the physical origins of the additional peak. Using these results, we explain the connection between our system, a three-level system in V-configuration where both transitions are laser driven, and a related experiment which was recently reported.

description: The reported nightly mean value of the circular polarization of optical emission observed from the close binary system AE Aqr is 0.06% (+-) 0.01%. We discuss a possibility that the observed polarized radiation is emitted mainly by the white dwarf or its vicinity. We demonstrate that this hypothesis is rather unlikely since the contribution of the white dwarf to the optical radiation of the system is too small. This indicates that the polarimetric data on AE Aqr cannot be used for the evaluation of the surface magnetic field strength of the white dwarf in this system.

Lyman Radiation Hydrodynamics of Turbulent H II Regions in Molecular Clouds: A Physical Origin of LyC Leakage and the Associated Ly$α$ Spectra

subject: FOS: Physical sciences

description: We examine Lyman continuum (LyC) leakage through H II regions regulated by turbulence and radiative feedback in a giant molecular cloud in the context of fully-coupled radiation hydrodynamics (RHD). The physical relations of the LyC escape with H I covering fraction, kinematics, spectral hardness, and the emergent Lyman-$α$ (Ly$α$) line profiles are studied using a series of RHD turbulence simulations performed with RAMSES-RT. The turbulence-regulated mechanism allows ionizing photons to leak out at early times before the onset of supernova feedback. The LyC photons escape through turbulence-generated low column density channels which are evacuated efficiently by radiative feedback via photoheating-induced shocks across the D-type ionization fronts. Ly$α$ photons funnel through the photoionized channels along the paths of LyC escape, resulting in a diverse Ly$α$ spectral morphology including narrow double-peaked profiles. The Ly$α$ peak separation is controlled by the residual H I column density of the channels and the line asymmetry correlates with the porosity and multiphase structure of the H II region. This mechanism through the turbulent H II regions can naturally reproduce the observed Ly$α$ spectral characteristics of some of LyC-leaking galaxies. This RHD turbulence-origin provides an appealing hypothesis to explain high LyC leakage from very young ($\sim3$ Myr) star-forming galaxies found in the local Universe without need of extreme galactic outflows nor supernova feedback. We discuss the implications of the turbulent H II regions on other nebular emission lines and a possible observational test with the Magellanic System and local blue compact dwarf galaxies as analogs of reionization-era systems.

description: It was suggested earlier that the gravitational redshift formula can be invalid when the effect of the backscattering is strong. It is demonstrated here numerically, for an exemplary electromagnetic pulse that is: i) initially located very close to the horizon of a Schwarzschild black hole and ii) strongly backscattered, that a mean frequency does not obey the standard redshift formula. Redshifts appear to depend on the frequency and there manifests a backscatter-induced blueshift in the outgoing radiation.

description: A simple, highly sensitive, precise and accurate liquid chromatographic mass spectroscopic (LC-MS/MS) method has been developed and validated for simultaneous quantification of Leucovorin and its metabolite 5-Methyl tetrahydrofolic acid in human plasma using Leucovorin-d4 and 5-Methyl-d3 tetrahydrofolic acid as internal standard (IS), respectively. The analytes were extracted from human plasma by solid phase extraction (SPE) technique using ion exchange cartridges. Chromatographic separation was achieved with reversed phase column chromatography. API 5500 LC-MS/MS in multiple reactions monitoring (MRM) was used for detection. Obtained results revealed that the method had a short sample preparation time as well as a chromatographic run time of just 3.0 min. In summary our results suggest that the validated method fulfilled all preset criteria for sensitivity, specificity, linearity (5.0-700.0 ng/mL), inter-and intra-accuracy and precision for both molecules.

description: The Casimir force is calculated analytically for configurations of two parallel plates and a spherical lens (sphere) above a plate with account of nonzero temperature, finite conductivity of the boundary metal and surface roughness. The permittivity of the metal is described by the plasma model. It is proved that in case of the plasma model the scattering formalism of quantum field theory in Matsubara formulation underlying Lifshitz formula is well defined and no modifications are needed concerning the zero-frequency contribution. The temperature correction to the Casimir force is found completely with respect to temperature and perturbatively (up to the second order in the relative penetration depth of electromagnetic zero-point oscillations into the metal) with respect to finite conductivity. The asymptotics of low and high temperatures are presented and contributions of longitudinal and perpendicular modes are determined separately. Serving as an example, aluminium test bodies are considered showing good agreement between the obtained analytical results and previously performed numerical computations. The roughness correction is formally included and formulas are given permitting to calculate the Casimir force under the influence of all relevant factors.

Subjects: subject: Copyright, intellectual property, cultural heritage law, open access, public domain, Open GLAM.

description: This dissertation examines the history and practice of making and commercializing reproductions of artworks and the legal considerations that arise. For centuries, business models have been based on reproducing copyright-free works using the technologies available, often claiming new rights and commercializing the results, especially by those responsible for their care. In the past two decades, new technologies have made this practice both easier and more visible by the Internet. Meanwhile, the role of copyright during the digitization of public domain works has become the focus of significant legal and social controversy. Questions arise under copyright law concerning the originality, authorship, ownership and legal status of surrogates. Yet how the law might protect reproductions remains unsettled. For decades, courts and legislature have failed to meaningfully resolve the issue at, what seems to be, its most basic level: whether copyright might arise in two-dimensional photographic reproductions of two-dimensional public domain works. In the absence of binding guidance, owners continue to assert intellectual property rights in surrogates, restricting the use of material which may rightfully reside in the public domain. As technologies move toward 3D, virtual, and AI-generated reproduction, the normative functions of copyright, authorship, surrogates, and the public domain are being influenced more by industry leaders than by lawmakers due to the lack of legal clarity. This research examines the impact of these historical and contemporary practices on access to and reuse of our common cultural heritage in the public domain. In doing so, it puts forward not only a framework for discussing the function of surrogate works in society, but also terminology useful for discussing the exercise of surrogate IP rights in the cultural sector. The analysis suggests that in the absence of clear legal guidance directing otherwise, further privatization of the public domain will proceed at the cost of future innovation, cultural growth, and the generation of knowledge in an information society. For this reason, this dissertation argues a fundamental shift is necessary in how surrogates are viewed, regulated, and commercialized, exploring not only how, but why.

Completely Positive Quantum Trajectories with Applications to Quantum State Smoothing

Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)

description: Here, we are concerned with comparing estimation schemes for the quantum state under continuous measurement (quantum trajectories), namely quantum state filtering and, as introduced by us [Phys. Rev. Lett. 115, 180407 (2015)], quantum state smoothing. Unfortunately, the cumulative errors in the most typical simulations of quantum trajectories with a total time of simulation $T$ can reach orders of $T Δt$. Moreover, these errors may correspond to deviations from valid quantum evolution as described by a completely positive map. Here we introduce a higher-order method that reduces the cumulative errors in the complete positivity of the evolution to of order $TΔt^2$, whether for linear (unnormalised) or nonlinear (normalised) quantum trajectories. Our method also guarantees that the discrepancy in the average evolution between different detection methods (different `unravellings', such as quantum jumps or quantum diffusion) is similarly small. This equivalence is essential for comparing quantum state filtering to quantum state smoothing, as the latter assumes that all irreversible evolution is unravelled, although the estimator only has direct knowledge of some records. In particular, here we compare, for the first time, the average difference between filtering and smoothing conditioned on an event of which the estimator lacks direct knowledge: a photon detection within a certain time window. We find that the smoothed state is actually {\em less pure}, both before and after the time of the jump. Similarly, the fidelity of the smoothed state with the `true' (maximal knowledge) state is also lower than that of the filtered state before the jump. However, after the jump, the fidelity of the smoothed state is higher.

It specially analyses trends, concerning regional differences in the volume, dynamics and structure of production and trade of apples, plums, cherries and sour cherries, strawberries, raspberries and grapes. Regions, i.e. countries, the largest producers and largest exporters and importers of these products have been defined. Subsequently, it was found that there are very significant regional differences which is the consequence of numerous natural, economic and social factors. In the analysis of character of relations and the degree of influence of aformentioned factors on changes and development directions of the observed phenomenon, quantitative and qualitative market research methods were used.

description: Up to now, only a very small number of dwarf novae have been studied during their outburst state (~30 per cent in the Northern hemisphere). In this paper we present the first comprehensive atlas of outburst spectra of dwarf novae. We study possible correlations between the emission and absorption lines seen in the spectra and some fundamental parameters of the binaries. We find that out of the 48 spectra presented, 12 systems apart from IP Peg show strong HeII in emission: SS Aur, HL CMa, TU Crt, EM Cyg, SS Cyg, EX Dra, U Gem, HX Peg, GK Per, KT Per, V893 Sco, IY UMa, and 7 others less prominently: FO And, V542 Cyg, BI Ori, TY Psc, VZ Pyx, ER UMa, and SS UMi. We conclude that these systems are good targets for finding spiral structure in their accretion discs during outburst if models of Smak (2001) and Ogilvie (2001) are correct. This is confirmed by the fact that hints of spiral asymmetries have already been found in the discs of SS Cyg, EX Dra and U Gem.

Subjects: subject: FOS: Medical engineering

description: The objectives of this study were to analyze effects of day-long exposure to LBP risk factors on lumbo-pelvic coordination (LPC) in nursing occupations and to verify if physical activity level affects diurnal work-related changes in LPC. Thirty-three nurses were recruited into three groups based on workplace physical demands and each completed two data collection sessions, one before and one after their 8-12 hour work shift. Participants completed several stationary trunk forward-bending/backward-return exercises at self-selected “fast” and “slow” rotational speeds, and while holding a 15 lbs. load. Kinematic data collected during these exercises were then used to characterize the timing and magnitude aspects of LPC during each exercise. We did not find any work-related changes in our measures of LPC, however, significant differences among groups were seen in thoracic rotation for all exercises (F> 13.39, p< .03) and pelvic rotation during the slow exercise (F= 3.678, p= .037). Considering earlier reports of changes in LPC following a short period of exposure to a single LBP risk factor, our results suggest that such changes when exposed to multiple risk factors and over the course of work day do not accumulate and likely recover by the end of work day.

description: The evolution of rural entrepreneurship is intrinsic to multifunctional rural development. Entrepreneurship is not just a part of economic development - it is the basis of long-term economic development. Accession to the EU brought new opportunities for rural entrepreneurship and financial sources: start-up and investment capital. The study is aimed at outlining the framework of analysis for policy aspects of entrepreneurship development in Poland after accession to the European Union. Analyse shows positive influence of EU co-financed measures on entrepreneurship development in Poland however it is still the state main role to promote development of non-agricultural activities on rural areas is not only support through EU-programmes but also by implementing favourable tax policy as well as improvement of the legislation quality.

description: We propose a theoretical method for enantio-discrimination based on the light deflection effect in four-level models of chiral molecules. This four-level model consists of a cyclic three-level subsystem coupled by three strong driving fields and an auxiliary level connected to the cyclic three-level subsystem by a weak probe field. It is shown that the induced refractive index for the weak probe field is chirality-dependent. Thus it will lead to chirality-dependent light deflection when the intensities of two of the three strong driving fields are spatially inhomogeneous. As a result, the deflection angle of the weak probe light can be utilized to detect the chirality of pure enantiomers and enantiomeric excess of chiral mixture. Therefore, our method may act as a tool for enantio-discrimination.

description: We propose the first association of an optical counterpart with a luminous supersoft X-ray source in M31, RX J0044.0+4118, observed with ROSAT in July 1991. The PSPC position is at 1.6" angular distance from a candidate nova in outburst in September of 1990. This is interesting because the incidence of classical novae among supersoft X-ray sources is an open question. The proposed optical counterpart was measured at R~17.7 in September of 1990, and it had faded to R>19.2 when it was observed again after 70 days. The light curve was too sparsely monitored for definite conclusions on the speed class of the nova. No other variable objects with V<23.5 were found in the ROSAT spatial error box. We evaluate that the probability that a classical or recurrent nova was in outburst in the ROSAT error box in the few years preceding the observation is very small, so the proposed identification is meaningful. We also show evidence that the associated supersoft X-ray source turned off in the third year after the outburst.

description: Removal of Cr(VI) from aquatic environment is crucial due to its bioaccumulation, high mobility and strong toxicity. In this work, a novel nano-adsorbent consisting of carbonate hydroxyapatite (CHAP) and carboxymethyl cellulose (CMC) was designed and successfully synthesized by a simple route for the uptake of Cr(VI). The synthetic CMC bridged CHAP (CMC-CHAP) material exhibited higher surface area (122.90 m2/g) and adsorption capacity for Cr(VI) (13.45 mg/g) than other apatite based adsorbents. The adsorption process of Cr(VI) by CMC-CHAP was in line with the Langmuir isotherm model and pseudo-second-order kinetic model. The calculated thermodynamic parameters showed that the adsorption of Cr(VI) on CMC-CHAP was a spontaneously endothermic process. In addition, CMC-CHAP had good ability to remove Cr(VI) under the interference of coexisting ions, and possessed remarkable reusability. Based on the pH-effect experiment and x-ray photoelectron spectroscopy characterization, the removal of Cr(VI) by CMC-CHAP was considered to be synergistic processes of electrostatic attraction, reduction reaction and chelation. This work provided new insights into performance optimization and application potential of CMC-CHAP on Cr(VI) removal from water.
Modelling Lagrangian velocity and acceleration in turbulent flows as infinitely differentiable stochastic processes

description: We develop a stochastic model for Lagrangian velocity as it is observed in experimental and numerical fully developed turbulent flows. We define it as the unique statistically stationary solution of a causal dynamics, given by a stochastic differential equation. In comparison to previously proposed stochastic models, the obtained process is infinitely differentiable at a given finite Reynolds number, and its second-order statistical properties converge to those of an Ornstein-Uhlenbeck process in the infinite Reynolds number limit. In this limit, it exhibits furthermore intermittent scaling properties, as they can be quantified using higher-order statistics. To achieve this, we begin with generalizing the two-layered embedded stochastic process of Sawford (1991) by considering an infinite number of layers. We then study, both theoretically and numerically, the convergence towards a smooth (i.e. infinitely differentiable) Gaussian process. To include intermittent corrections, we follow similar considerations as for the multifractal random walk of Bacry et al. (2001). We derive in an exact manner the statistical properties of this process, and compare them to those estimated from Lagrangian trajectories extracted from numerically simulated turbulent flows. Key predictions of the multifractal formalism regarding acceleration correlation function and high-order structure functions are also derived. Through these predictions, we understand phenomenologically peculiar behaviours of the fluctuations in the dissipative range, that are not reproduced by our stochastic process. The proposed theoretical method regarding the modelling of infinitely differentiability opens the route to the full stochastic modelling of velocity, including the peculiar action of viscosity on the very fine scales.

description: Spontaneous and stochastic reversal of large scale flow structure is an intriguing and crucial phenomenon in turbulent Rayleigh-Bénard type natural convection. This paper proposes a new control approach to eliminate the reversals through stabilising the corner flows using two small sidewall controllers. Based on a series of direct numerical simulations, it is shown that the control can successfully stop the growth of corner vortices and suppress the reversal of large-scale circulation, if the width of sidewall controllers installed within or near the top of corner vortices is large enough. When the controllers are located around the centre, they can easily break up the large-scale structures or even divide the single roll mode into a double-roll mode for very large widths. Moreover, the influence of sidewall controllers on the heat transport is studied. It is shown that the heat transport efficiency can be slightly enhanced or suppressed when the proper location and width are chosen. The present findings provide a new idea to control the large-scale flow structure and reversals in thermally driven convection through sidewall controlling.

description: Irrigation contributes to increased agricultural yields and production volume and intensified agricultural production. Field crops double their yields in irrigation. Production value of irrigated field crops is increased 2.06 times compared with dry farming. Profit per hectare of irrigated field crops is increased 2.01 times. The economy of field crop production increases from 1.03 in dry farming to 1.18 in irrigation. Profitability of field crop production increases from 3% in dry farming to 18.4% in irrigation. Productivity of production of irrigated field crops increases 1.6 times for wheat, 2.4 times for corn, 1.9 times for sugar beet, 2.4 times for sunflower and 2.7 times for soybean (yield/work hour). High economy of production is achieved in vegetable production, amounting to 2. Profitability is increased by 75%. Profit per hectare of irrigated vegetable crops exceeds that of irrigated field crops. Investments in irrigation result in higher volume and quality of food production, more economic and profitable production, and higher incomes and profits. Irrigation has a decisive impact on yield performance, production and economic results and further development of market-oriented, certified organic production of high quality produce.
