Oscillation of Thermal Insulation Three-Layer Cylindrical Pipes under Operating Loads
Authors: Lugovoi P. , Shugailo O. , Orlenko V. , Diemienkov V.
Published: September 2020

Equipment and pipes are the main components of a nuclear power plant (NPP) that ensure transfer of heat energy into electric one. The pipes with nominal diameter from DN10 to DN1200 are the main types of pipes that also include different fragments such as bends, cones, tees, branches, etc. Common length of all NPP pipes is hundreds of kilometers. All these components can be combined by one common feature: they are shell structures that found wide application in daily activities. The use of such components in the design and manufacture of equipment and pipelines of NPP power units requires appropriate practical and theoretical studies. The use of filler made of light materials allows for a small increase in the weight of the structure to significantly increase its bending stiffness and improve its thermal insulation properties. The oscillations of three-layer cylindrical pipes are considered in this paper. The equations of motion of a three-layer cylindrical shell with lightweight filler reinforced by stiffening ribs with non-stationary loading have been provided through these efforts. The model of Timoshenko’s theory of shells and rods have been used in this study under analysis of components with flexible structures. Numerical results of oscillations of the three-layer elastic structure were obtained using the finite element method. The impact of the physical and mechanical parameters of the shell layers is investigated on its stress strain state under an axisymmetric internal impulse loading.

Drukarz i pastorówna. Panegiryki okolicznościowe z okazji zaślubin Fryderyka Ludwika Rhete z Anną Reimar 22 września 1686 r.
Authors: Ochmański Mikołaj
Published: September 2020

Na wstępie artykułu Autor przedstawia pokrótce relacje druk-drukarstwo-Kościół stwierdzając, że szczególnym odbiorcą czarnej sztuki stał się właśnie Kościół, katolicki i oczywiście reformowany. W tym kontekście Autor skupił się na roli druków ulotnych i okolicznościowych, analizując następnie na przykładzie Gdańska, Królewca i Szczecina ich znaczenie w krajobrazie informacyjnym siedemnastowiecznych miast. Jednym z drukarzy szczecińskich, który często tłoczył druki tego typu, był Fryderyk Ludwik Rhete. To właśnie on wydał kilka epitalamiów z okazji własnego ślubu z Anną Reimar we wrześniu 1686 r. Treść i funkcje tych publikacji są przedmiotem szczegółowej analizy Autora. Wynika z niej, że zaślubiny drukarza stały się dla autorów panegiryków pretekstem do wychwalania zasług drukarstwa, jako narzędzia propagandy religijnej. Działanie drukarstwa na rzecz wiary, rozpowszechnianie przez drukarzy Słowa Bożego stanowiło zatem wedle panegirystów właściwe wykorzystanie czarnej sztuki, bo prowadziło do szczęścia wiecznego.

Authors: Rabczun Oksana
Published: September 2020

W zbiorach Biblioteki Narodowej Ukrainy im. W.I. Wernadskiego w Kijowie przechowywana jest znaczna liczba księgozbiorów, których historia związana jest z dziejami i kulturą Polski. Autorka zajmuje się w artykule jednym z nich – księgozbiorem rodowym Urbanowskich i Starzyńskich, znanych polskich rodzin szlacheckich z Podola (obecnie region Ukrainy). Dotąd niezbadany zbiór, którego historia sięga końca XVIII w., nosi nazwę Biblioteki Zahinieckiej od miejsca pierwotnego jego gromadzenia i przechowywania – wsi Zahińce w powiecie latyczowskim (obecnie ukraiński obwód chmielnicki). Według różnych źródeł w momencie przewiezienia Biblioteki Zahinieckiej do Kijowa (w 1917 r.) liczyła ona od 16 000 do 20 00 tomów. W Kijowie część tych zbiorów trafiła do różnych działów Centralnej Biblioteki Naukowej Ukrainy (obecna Biblioteka Narodowa Ukrainy im. W.I. Wernadskiego). Artykuł składa się z dwóch części. W pierwszej Autorka rekonstruuje dzieje i zawartość biblioteki Urbanowskich-Starzyńskich – typowej dla polskich bibliotek ziemiańskich z Wołynia, Podola i Kijowszczyzny (obecnie Ukraina). W drugiej części podaje wykaz przykładowych druków z XVI-XIX w. pochodzących z tego księgozbioru. Artykuł kończą informacje na temat opraw i ekslibrisu heraldycznego Biblioteki Zahinieckiej.
„Kłosy” o książce i prasie w Galicji (1865-1890)
Authors: Fortuna Dorota
Published: September 2020

Artykuł stanowi próbę spojrzenia na problemy polskiego ruchu wydawniczego w zaborze austriackim w drugiej połowie XIX w. z perspektywy informacji zawartych w tygodniku ilustrowanym „Kłosy”, który ukazywał się w Warszawie w latach 1856-1890. Choć czasopismo wydawano w stolicy Królestwa Polskiego, to jednak informowało ono o sprawach książki i prasy także w innych zaborach, zwłaszcza w zaborze austriackim – Galicji. Autorka skupiła się na przedstawianym w „Kłosach” obrazie ruchu wydawniczego właśnie w Galicji. Po krótkim zarysie sytuacji społeczno-politycznej w zaborze austriackim, następne fragmenty artykułu poświęciła: roli Lwowa w życiu literackim, naukowym i wydawniczym oraz czytelnictwu książki i prasy w Galicji; działalności bibliotek i czytelń Towarzystwa Oświaty Ludowej założonego w 1881 r. we Lwowie; znaczeniu tzw. literatury ludowej dla szerzenia oświaty w ubogich warstwach społecznych; działalności Komitetu Wydawnictw Dziełek Ludowych i Macierzy Polskiej; galicyjskim wydawnictwom szkolnym, naukowym, fachowym i prasowym omawianym na łamach „Kłosów”. Z analizy Autorki wynika, że zainteresowanie warszawskich „Kłosów” skupiało się zwłaszcza na problemie oświaty ludu, upowszechniania czytelnictwa w Galicji.

Authors: Pajač Živković Ivana , Lemić Darija , Duralija Boris , Mešić Aleksandar , Čirjak Dana
Published: September 2020

Spotted wing drosophila (Drosophila suzukii (Matsumura, 1931)) a polyphagous alien invasive species causes economic damages in cultivation of soft fruits all over the word. It is widespread in Croatia and considering that the economic damage occurred in greenhouse cultivation of soft fruit several years ago, new damage in this production can be expected. The pest development was monitored on 50 overripe fruits of cultivars 'Amira' and 'Sugana' cultivated in greenhouses in Zagreb in 2018 to investigate pest preference for these cultivars and to make a risk assessment in raspberry cultivation. Pest presence was recorded on both cultivars at the same time, and D. suzukii was dominant drosophilid species in development. Significantly more drosophilids as well as individuals of D. suzukii were developed on cultivar 'Amira'. On 'Amira' 373 female and 211 male of D. suzukii developed, while on 'Sugana' 253 female and 142 males developed. Average number of pests per fruit on 'Amira' counted 11.68 and on 'Sugana' 7.9. Drosophila suzukii develops in high populations in the greenhouse production of raspberry cultivars, which poses a serious risk for their cultivation in the study site.

Voštana prevlaka površine kožice ploda šljive ključna je prepreka gubitku vode prilikom postupka sušenja te ju je nužno ukloniti. Cilj ovog rada bio je istražiti utjecaj primjene različitih predtretmana, kemijskog (primjenom lužine), fizikalnog (primjenom abrazije) i toplinskog (ugrijanom destiliranom vodom) na vrijeme sušenja plodova šljive sorte 'President'. Također, varirani su i ključni parametri svakog pojedinog predtretmana poput temperature otopine prilikom toplinskog (22 i 60 °C), koncentracije (0,5, 1 i 1,5% v/v) i temperature (22 i 60 °C) lužine (KOH) kod kemijskog i vremenskog perioda abrazije (5, 10 i 15 min) kod fizikalnog. Prema dobivenim rezultatima, kemijski predtretman lužinom koncentracije 1 i 1,5% temperature 60 °C bio je najučinkovitiji, vrijeme sušenja iznosilo je svega 27 sati, adok je samo 2 sata dulje (29 h) trajalo sušenje plodova predtretiranih abrazijom u vremenu od 15 min. Temeljem svega, može se zaključiti kako je fizikalni predtretman abrazijom izrazito učinkovit u uklanjanju voštane prevlake, time i u skraćivanju vremena sušenja plodova šljive, a isto tako treba naglasiti kako primjenom abrazivnog predtretmana značajno utječemo na smanjenje onečišćenja okoliša, ali i na zdravlje ljudi, s obzirom da nema ostataka kemijskih sredstava koja nakon primjene treba adekvatno zbrinuti, jer potencijalno mogu negativno utjecati na čovjeka i okoliš.

Authors: Kumar R. , Singh S. N.
Published: September 2020

Electronic states of a single electron in doubly eccentric cylindrical quantum wire are theoretically investigated in this paper. The motion of electron in quantum wire is free along axial direction in a cylindrical quantum wire and restricted in annular regions by three different parallel finite cylindrical barriers as soft wall confinement. The effective mass Schrödinger equation with effective mass boundary conditions is used to find energy eigenvalues and   corresponding wavefunctions. Addition theorem for cylindrical Bessel functions is used to shift the origin for applying boundary conditions at different circular boundaries. Fourier expansion is applied after addition theorem to get wavefunctions in analytical form. A determinant equation is obtained as a result of applications of effective mass boundary conditions which roots gives energy of various electronic states. The lowest root gives ground state energy. The variation in ground state energy with eccentricity is obtained numerically and presented graphically. Electronic states in massive wall confinement and hard wall confinement is further obtained as limiting behavior of the states obtained in soft wall confinement. The knowledge of electronic states in such cylindrical hetrostructures semiconductor material can lead to improve the efficiency of many quantum devices.
Mathematical Model and Solution for an Unsteady MHD Fourth Grade Fluid Flow over a Vertical Plate in a Porous Medium with Magnetic Field and Suction/Injection Effects
Authors: Fenuga O. J. , Aroloye S. J. , Salawu S. O.
Published: September 2020

This work investigates the mathematical model and solution for an unsteady MHD fourth grade fluid flow over a vertical plate in a porous medium with the effects of the magnetic field and suction/injection parameters using Homotopy Perturbation Method. The flow is considered to satisfy the constitutive equations of fourth grade fluid flow model and because of the Homotopy Perturbation Method used, only the momentum equation with initial and boundary conditions are solved as governing equations. After initializing stability test, the convergence of the governing equations are observed graphically using the results of Homotopy Perturbation Method with the new analytical method used by Yurusoy in literature and there is a perfect agreement in results. The impact of dimensionless second, third and fourth grade parameters with the effects of magnetic field and suction/injection parameters on the velocity field are displayed graphically and discussed. Increase in suction parameter decreases the momentum boundary layer thickness while injection parameter enhances velocity distribution in the boundary layer. Magnetic field reduces velocity throughout the boundary layer because the Lorentz force which acts as retarding force reduces the boundary layer thickness.
Effect of Al2O3 Nanoparticles and Cylindrical Pins on Natural Convection Heat Transfer in a C-Shaped Enclosure
Authors: Arafat M. Y. , Faisal F.
Published: September 2020

A numerical study has been conducted to investigate the transport mechanism of natural convection in a C-shaped enclosure filled with water-Al2O3 nanofluid for various pertinent parameters. The effects of the volume fraction of the Al2O3 nanoparticles, Rayleigh number, and radius of inserted cylindrical pins on the temperature, velocity, heat flux profiles and average Nusselt number have been investigated. General correlations for the effective thermal conductivity and viscosity of nanofluids are used for this analysis. The governing mass, momentum and energy equations are solved numerically with the finite volume method using the SIMPLER algorithm. The results show that addition of nanoparticle improves the heat transfer performance. Insertion of cylindrical pins of lower radius increases the average Nusselt number irrespective of Rayleigh number. But anomaly has been observed while pins of higher radius are inserted due to enormous disturbance in the fluid.
On the Total Vertex Irregular Labeling of Proper Interval Graphs
Authors: Rana A.
Published: September 2020

A labeling of a graph is a mapping that maps some set of graph elements to a set of numbers (usually positive integers).  For a simple graph G = (V, E) with vertex set V and edge set E, a labeling  Φ: V ∪ E → {1, 2, ..., k} is called total k-labeling. The associated vertex weight of a vertex x∈ V under a total k-labeling  Φ is defined as wt(x) = Φ(x) + ∑y∈N(x) Φ(xy) where N(x) is the set of neighbors of the vertex x. A total k-labeling is deﬁned to be a vertex irregular total labeling of a graph, if for every two different vertices x and y of G, wt(x)≠wt(y). The minimum k for which  a graph G has a vertex irregular total k-labeling is called the total vertex irregularity strength of G, tvs(G). In this paper, total vertex irregularity strength of interval graphs is studied. In particular, an efficient algorithm is designed to compute tvs of proper interval graphs and bounds of tvs is presented for interval graphs.

Authors: Mozumder M. S. I. , Hossain M. D.
Published: September 2020

Nitrogen, mostly in the form of ammonia or nitrate containing wastewater deteriorated the water quality which simultaneously affects environment, plants, animals and human life. A number of researchers nowadays are conducting research to find out efficient and cost effective nitrogen removal technique along with optimum operating parameters. It is very important to uncover the optimum range of each parameter. In this study, it was winnowed to elicit the optimum operating ranges of dissolved oxygen concentration, temperature, pH, free ammonia concentration, nitrate concentration and culture medium. The nitrogen removal techniques were compared, evaluated considering advantages and disadvantages of them. Partial nitrification combined with anaerobic ammonium oxidation was found most prospective nitrogen removal technique for wastewater treatment compare to other techniques (conventional nitrification-denitrification over nitrate/nitrite, anammox, SND etc.) due to less oxygen consumption (62.5 % less), less sludge production, no carbon requirement, single reactor used and energy efficiency. SND process was more economical due to faster consumption of ammonia, nitrite and nitrate. There was various culture mediums which had a favorable or detrimental effect on specific nitrogen removal processes. However for desired bacteria culture for specific application, suitable culture medium needs to be selected considering the optimal operating parameters for microbial growth.

Authors: Manju V. V. , Divakara S. , Somashekar R.
Published: September 2020

The comprehensive elastic properties of Suvin cotton fibre have been estimated. The Linked Atom Least Square method (LALS) technique has been employed to compute the structural properties using the X-ray diffraction data. Using Treloar’s assumptions the elastic stiffness matrix |Cij| has been calculated, then by utilizing the Voigt theory the elastic constants like Young’s modulus (E), Bulk modulus (K), Shear modulus (G), Poisson’s ratio (ν) and linear compressibility (β) have been estimated. Further, the experimental results of elastic constants are obtained and compared with the computed results and a broad correlation between them has been observed. ELATE web application tool is used to obtain the 3-dimensional images of variation of elastic constants along their spatial axes. From these figures an attempt has been made to explain the anisotropic mechanical property with respect to directional dependent Young’s modulus (E) and Shear modulus properties (G).

Published: September 2020

The National Neisseria Network (NNN), Australia, comprises reference laboratories in each state and territory that report data on susceptibility profiles for clinical Neisseria gonorrhoeae isolates from each jurisdiction for an agreed group of antimicrobial agents, for the Australian Gonococcal Surveillance Programme (AGSP). The antibiotics are ceftriaxone, azithromycin, ciprofloxacin and penicillin; they represent current or potential agents used for the treatment of gonorrhoea. Ceftriaxone combined with azithromycin is the recommended treatment regimen for gonorrhoea in the majority of Australia. However, there are substantial geographic differences in susceptibility patterns in Australia, with certain remote regions of the Northern Territory and Western Australia having low gonococcal antimicrobial resistance rates. In these regions, an oral treatment regimen comprising amoxycillin, probenecid and azithromycin is recommended for the treatment of gonorrhoea. Additional data on other antibiotics are reported in the AGSP Annual Report. The AGSP has a programme-specific quality assurance process.

Authors: Atalah J , Fletcher LM , Davidson IC , South PM , Forrest BM
Published: September 2020

The global proliferation of marine artificial habitats is rapidly altering the physical structure of coastlines, with knock-on effects on physical, chemical, and ecological processes at seascape scales. Ecological consequences of maritime sprawl associated with aquaculture are poorly understood, despite the fact that these suspended structures are particularly prone to biofouling, which can affect the industry and seascape around it. We characterised seascape-scale spatial and temporal distribution patterns of 10 biofouling taxa in relation to the presence and distance to Perna canaliculus mussel farms in New Zealand’s largest aquaculture region. Seven of 10 taxa had significantly higher cover on farms than in natural habitats throughout the region. The cover of 4 of those 7 taxa, including the high-profile pests Mytilus galloprovincialis and Undaria pinnatifida, exponentially decreased with distance from the nearest farm, while some taxa were absent from natural habitats (e.g. the ascidian Ciona robusta). In contrast, several opportunistic macroalgal species, such as Cladophora ruchingeri and Pylaiella littoralis, had colonised extensive areas of natural habitat. Our results suggest that biofouling is a persistent issue on mussel farms and that farm structures may act as reservoirs or ‘stepping stones’ for the dispersal of potential marine pests. These distributional and dispersal patterns can inform integrated pest management efforts focusing on spatial management strategies, such as ‘firebreaks’ in farm connectivity, avoidance of pest hotspots, and farm fallowing.

Hong Kong: The Crack-up
Authors: Hong Frank
Published: September 2020

Hong Kong is typically celebrated as the Oriental Pearl owing its prosperity to a free economy and the British rule of law, and lately the front line of a pro-democracy movement that courageously confronts the authoritarian sovereign to its north. In reality, Hong Kong, as ominously foretold by its geographic features, has been cracking up like a plate. This metaphor is more of a methodological insight than a mere rhetoric device in that it takes nothing short of a rigorous analysis at the micro level to overcome the deeply entrenched bending of the nearly two-century long arc of Hong Kong’s life for geopolitical and propaganda purposes at various junctures. This Essay is an exercise of critical phenomenology that seeks to challenge the grand myth of Hong Kong’s autonomy and expose the lines of flight that have caused unrest in Hong Kong and fissures in America alike.

Background: Coronary artery dissection (CAD) sometimes accompanies unstable hemodynamics and requires mechanical cardiac support. Meanwhile, mechanical cardiac support may influence coronary hemodynamics in CAD. No study has examined the impact of Impella left ventricular (LV) support on CAD.

Materials and Methods: CAD was induced in eight Yorkshire pigs by injuring the left anterior descending artery (LAD) using a 0.018-in. stiff guidewire and/or deep engagement of a blunt-cut coronary guiding catheter. After the creation of CAD, hemodynamic parameters, coronary pressure, and flow as well as coronary angiograms were acquired before and after maximum LV support using the Impella CP.

Result: CADs with a large flap were successfully created by deep engagement of a blunt-tip guiding catheter with forceful contrast injection. One animal (#8) exhibited thrombolysis in myocardial infarction (TIMI)-1 flow, while the others (animals #1–#7) showed TIMI-2/3 flow. In TIMI-2/3 animals, maximal Impella support increased mean coronary pressure (108.4 ± 22.5 to 124.7 ± 28.0 mmHg, P < 0.001) with unchanged mean coronary flow velocity (63.50 ± 28.66 to 48.32 ± 13.30 cm/s, P = 0.17) of the LAD distal to the dissection. The LV end-diastolic pressure (20.6 ± 6.6 vs. 12.0 ± 3.4 mmHg, P = 0.032), LV end-diastolic volume (127 ± 32 vs. 97 ± 26 ml, P = 0.015), stroke volume (68 ± 16 vs. 48 ± 14 ml, P = 0.003), stroke work (5,744 ± 1,866 vs. 4,424 ± 1,650 mmHg·ml, P = 0.003), and heart rate (71.4 ± 6.6 vs. 64.9 ± 9.3/min, P = 0.014) were all significantly reduced by Impella support, indicating effective unloading of the LV. In the TIMI-1 animal (animal #8), maximal Impella support resulted in further delay in angiographic coronary flow and reduced distal coronary pressure (22.9–17.1 mmHg), together with increased false-lumen pressure.

Conclusion: Impella support effectively unloaded the LV and maintained the hemodynamics in a novel porcine model of CAD. Coronary pressure distal to the dissection was increased in TIMI-2/3 animals after Impella support but decreased in the animal with initial TIMI-1 flow.

Organic materials from various sources have been commonly adopted as soil amendments to improve crop productivity. Phosphorus deficiency and fixation in alkaline calcareous soils drives a reduction in crop production. A two-year field experiment was conducted to evaluate the impact of rock phosphate enriched composts and chemical fertilizers both individually and in combination with plant growth promoting rhizobacteria (PGPR) on wheat productivity and soil chemical and biological and biochemical properties. The present study demonstrates significant increments in crop agronomic and physiological parameters with Pseudomonas sp. inoculated RPEC1 (rock phosphate + poultry litter + Pseudomonas sp.) over the un-inoculated untreated control. However, among all other treatments i.e., RPEC2 (rock phosphate + poultry litter solubilized with Proteus sp.), RPC (rock phosphate + poultry litter), HDP (half dose inorganic P from Single Super Phosphate-SSP 18% P2O5) and SPLC (poultry litter only); RPEC1 remained the best by showing increases in soil chemical properties (available phosphorus, nitrate nitrogen, extractable potassium), biochemical properties (alkaline phosphatase activity) and biological properties (microbial biomass carbon and microbial biomass phosphorus). Economic analysis in terms of Value Cost Ratio (VCR) showed that the seed inoculation with Pseudomonas sp. in combination with RPEC1 gave maximum VCR (3.23:1) followed by RPEC2 (2.61:1), FDP (2.37:1), HDP (2.05:1) and SPLC (2.03:1). It is concluded that inoculated rock phosphate (RP) enriched compost (RPEC1) can be a substitute to costly chemical fertilizers and seed inoculation with Pseudomonas sp. may further increase the efficiency of composts.
