Authors: Montlevic V.M.
Published: October 2020

In this paper the possibility of using the method of successive calculations to solve the transportation problem on the maximum proﬁt is investigated. The feature of this problem is that a set of consumers isn’t deﬁned and gets out from wider set of possible consumers by the criterion of a maximum of proﬁt. Proﬁt is calculated on the basis of consumer demand and prices, which are determined by the contract between the consumer and the company carrying out transportation. It is shown that this problem is reduced to maximization of the proﬁt function deﬁned on the set of all subsets of consumers. The submodularity of proﬁt function is proved, that justiﬁed application of method of successive calculations to solve this problem.

ENTANGLEMENT OF ATOMS SUCCESIVELY PASSING A CAVITY TAKING INTO ACCOUNT THE STARK SHIFT
Authors: Bashkirov E.K.
Published: October 2020

In the article we consider the influence of dynamical Stark shift on entanglement degree of two atoms with degenerate two-photon transitions successively passing an ideal one-mode cavity. We suppose that the field be prepared in vacuum state and the atoms be prepared in coherent superposition of excited and ground states. Thus it was also supposed that atoms fly by the cavity for identical time. On the basis of exact expression of evolution operator we carried out atom-atom entanglement for different values of two-atom coherence parameters and different values of cavity flight time. It is shown that Stark shift of energy levels can be used for effective control on a degree of atomic entanglement.

Published: October 2020

The paper is devoted to analytical determination of coefficients of the Williams asymptotic expansion of the stress field in the neighborhood of two collinear crack tips in an infinite plate under mixed mode loading. On the basis of the Kolosof-Muskhelishvili approach the complete asymptotic expansion of the stress field in the vicinity of the crack tips of two collinear cracks of equal lengths under mixed mode loading is derived. The analysis of the higher order terms in the asymptotic expansion series is performed. It is clear that it is necessary to take into account the higher order terms.
Asymptotics of the stress ﬁeld near acrack tip under mixed - mode loading: small parameter method
Authors: Stepanova L.V. , Yakovleva E.M.
Published: October 2020

In the present paper approximate analytical and numeric solutions to nonlinear eigenvalue problems arising in nonlinear fracture mechanics in analysis of stress — strain fields near a crack tip under mixed mode loading are presented. Asymptotic solutions are obtained via perturbation method technique (small parameter method). The artificial small parameter is the difference between the eigenvalue corresponding to the nonlinear eigenvalue problem and the eigenvalue related to the linear ”undisturbed” problem. It is shown that the perturbation technique gives an effective method of solving nonlinear eigenvalue problems in nonlinear fracture mechanics. Comparison results of numeric and asymptotic results for different value of the mixity parameter and hardening exponent shows good agreement. Thus the perturbation theory technique for study of nonlinear eigenvalue problems is offered and applied for eigenvalue problems arising from fracture mechanics analysis in the case of mixed mode loading.

On the nonlinear eigenvalue problems arising in fracturemechanics
Authors: Yakovleva E.M.
Published: October 2020

In the article the stress-strain state near a Mode II crack tip under plane stress conditions in power-law materials is considered. It is noted that nowadays the whole eigenspectrum and orders of stress singularity at the crack tip for a power-law medium are of prevailing interest. Additional eigenvalues for the stress ﬁeld at a static mode II crack under plane stress condition are numerically obtained for diﬀerent values of the exponent n via the Runge-Kutta method in conjunction with the shooting method. However, in this case the shooting method is multi-parameter since it is necessary to select two parameters and, consequently, the results obtained require further veriﬁcation and justiﬁcation. For this purpose the technique developed in perturbation theory for study of nonlinear eigenvalue problems is oﬀered and applied for eigenvalue problems arising from fracture mechanics analysis.

On almost nilpotent varieties in theclass of commutative metabelian algebras
Authors: Mishchenko S.P. , Shulezhko O.V.
Published: October 2020

A well founded way of researching the linear algebra is the study of it using the identities, consequences of which is the identity of nilpotent. We know the Nagata-Higman’s theorem that says that associative algebra with nil condition of limited index over a ﬁeld of zero characteristic is nilpotent. It is well known the result of E.I.Zel’manov about nilpotent algebra with Engel identity. A set of linear algebras where a ﬁxed set of identities takes place, following A.I. Maltsev, is called a variety. The variety is called almost nilpotent if it is not nilpotent, but each its own subvariety is nilpotent. Here in the case of the main ﬁeld with zero characteristic, we proved that for any positive integer m there exist commutative metabelian almost nilpotent variety of exponent is equal to m.

DYNAMICS OF TWO-LEVEL ATOMS INTERACTING WITH THERMAL FIELD FOR ENTANGLED INITIAL ATOMIC STATES
Authors: Bashkirov E.K. , Solovieva A.S. , Mastyugin M.S.
Published: October 2020

In this paper the entanglement dynamics for system of two two-level atoms interacting with a mode of thermal electromagnetic ﬁeld in lossless cavity has been investigated. Initial atomic states are the entangled Bell type states. Using the full set of eigenvectors of the Hamiltonian of the considered model we have derived the exact solution for the density matrix for the whole system. On its basis the reduced atomic density matrix and Peres - Horodetcki parameter have been calculated. Calculating of entanglement parameter shows the possibility of high degree of entanglement even for large intensity of thermal ﬁeld. Thus there is a possibility of maintenance and control over the degree of entanglement.

We consider an initial-boundary problem with dynamic boundary condition for a hyperbolic equation in a rectangle. Dynamic boundary condition represents a relation between values of derivatives with respect of spacial variables of a required solution and first-order derivatives with respect to time variable. The main result lies in substantiation of solvability of this problem. We prove the existence and uniqueness of a generalized solution. The proof is based on the a priori estimates obtained in this paper, Galyorkins procedure and theproperties of Sobolev spaces.
Older Women’s Experiences in the Icelandic Workforce – Positive or Negative?
Authors: Sigurðardóttir Sigurveig H. , Snorradóttir Ásta
Published: October 2020

The purpose of the study is to gain a deeper understanding of older women’s experiences in the labour market, how they value their job opportunities and perceived attitudes towards them. Qualitative interviews were conducted with seven women aged 57–74 years who all have at least 10 years working experience after they turned 40. Experiencing discrimination in the workforce was often mentioned by the women. Their experience is that men are less discriminated against on grounds of age than women. Older women pride themselves for participating in the workforce for being reliable, unselfish and undemanding rather than being experienced, skillful and good at their jobs. The results indicate that it is important to research further the well-being of older women in the labour market and try to change the negative attitudes and discrimination that appear prevalent. Ageism against older women can affect their well-being and health and must be prevented.
Unions’ Conceptualizations of Members’ Professional Interests and Influence in the Workplace
Authors: Bie-Drivdal Arnhild
Published: October 2020

The role of unions as agents of professional knowledge is seldom addressed in studies on working life relations.This article investigates how unions with different degrees of professionalization con- ceptualize members’ interests and influence in the workplace. Two unions of professionals and one general union in the Norwegian public sector are compared. The data consist of union documents, speeches, and interviews with 12 workplace representatives. A ‘union logic’ and ‘professional association logic’ are developed and applied as analytical ideal types, and the unions’ conceptualizations and combinations of these institutional logics are analyzed. The article finds similarities and differences between the unions and interesting differences between the unions’ micro and macro levels. Further, a distinct hybrid logic is identified as a ‘union of professionals logic’, with professional influence and the agency of elected representatives as key aspects. Introducing perspectives from the study of professions, the article contributes to a reconceptualization of the study of unions within the Nordic model – and beyond.
Women in the Steel Industry: Closed in Corners or Provided with Possibilities
Authors: Salminen-Karlsson Minna
Published: October 2020

The steel industry has been one of the basic industries in both Sweden and Finland. It is in a process of change, where research and development play an increasingly prominent role. In Sweden in particular, there is also an ambition to increase the number of women in the industry. This study is based on interviews and workshops with 12 women working in researcher or managerial positions in the Swedish steel industry. Their experiences show that employing more women in the industry is not enough to make effective use of the female talent pool, nor to increase gender equality. Besides belonging to a gender minority, women often had different backgrounds and career paths from their male colleagues, and their organizations need to be able to recognize the value of untraditional characteristics. The organizational environment determined whether these women became just an improvement in gender statistics or real gains in the quest for competence.

Modeling the Impact of the COVID-19 Pandemic on First Nations, Metis, and Inuit Communities: Some Considerations
Authors: Lavoie Josée , Romanescu Razvan G. , Katz Alan , Nickel Nathan
Published: October 2020

Objectives: This article articulates the complexity of modeling in First Nations, Metis, and Inuit contexts by providing the results of a modeling exercise completed at the request of the First Nations Health and Social Secretariat of Manitoba. 

Methods: We developed a model using the impact of a previous pandemic (the 2009 H1N1) to generate estimates.

Results: The lack of readily available data has resulted in a model that assumes homogeneity of communities in terms of health status, behaviour, and infrastructure limitations. While homogeneity may be a reasonable assumption for province-wide planning, First Nation communities and Tribal Councils require more precise information in order to plan effectively. Metis and urban Inuit communities, in contrast, have access to much less information, making the role of Indigenous organizations mandated to serve the needs of these populations that much more difficult.

Conclusion: For many years, Indigenous organizations have advocated for the need to have access to current and precise data to meet their needs. The COVID-19 pandemic demonstrates the importance of timely and accurate community-based data to support pandemic responses.
A BORI-ÉLETMŰ DIMENZIÓI
Authors: FARAGÓ Kornélia
Published: October 2020

A tanulmány Bori Imre széles keretű világának némely korai szerkezeti jellemzőit igyekszik számba venni, a többes dimenzionalitás összetett viszonyrendszerét kutatva. A modernitás meghatározó kérdésköreinek azonosításával, az avantgárd diskurzus értelmezői horizontba emelésével, a jugoszláv irodalmi viszonylatok látószögbe állításával, vagy például a prózavizsgálat test-tematikai újításaival ható irodalomtörténeti gondolkodás áll előttünk. Nemcsak a műfaji problematika, de az életmű tartalmi összetétele is szokatlanul bonyolult. Az egyik kiinduló kérdésünk az, hogy az irodalomtörténet-írás metaperspektívájából milyen esélyünk van az életmű korpuszának alapozó területeit, a szerepek egyes összetevőit egymás viszonylatában megragadni. Megkerülhetetlen a kérdés, hogy az életmű kezdeteitől előforduló kifejezésmodellek hogyan tesznek lehetővé egy egymással összefüggő rendszerben való látásmódot egy sajátos kisebbségi program bonyolult logikai keretei között, ahol a társadalmi pozíciók és lehetőségek speciális rendszerével is számolnunk kell.
AZ AVANTGÁRD RENDSZERE

Published: October 2020

Nehéz rá pontos szavakat találni, hogy Bori Imre milyen szerepet játszott a magyar avantgárd újrafelfedezésében és kanonizálásában a hatvanas évektől kezdődően. Könyvei és tanulmányai azóta fiatalabb nemzedékek sorát inspirálták, de éppilyen fontos volt az az inspiráció, amelyet magyarországi kortársainak, az avantgárdkutatás megalapozásában szintén kulcsszerepet játszó Szabolcsi Miklósnak, Béládi Miklósnak vagy Pomogáts Bélának nyújtott. Élénk viták jellemezték ezt az eszmecserét, s a felmerült kérdések némelyike máig sem jutott még nyugvópontra. Hűtlenek lennénk Bori Imre szelleméhez, ha mindenben automatikusan neki adnánk igazat. volt, amiben tévedett, de gondolkodásának következetes rendszerszerűsége lehetővé tette, hogy még e tévedések is új belátásokhoz vezessenek el. A felismerésekhez elvezető gondolati struktúrák az évtizedek távlatában olykor fontosabbnak és időtállóbbnak bizonyulnak maguknál a felismeréseknél. írásomban Bori professzornak az avantgárddal kapcsolatos rendszeralkotó munkájáról, felismeréseiről és hipotéziseiről kívánok áttekintést nyújtani az egyszerre hálás és kritikus utókor szemszögéből.

Authors: ERDOGAN Hakika , MUHSİNOGLU Orkun
Published: October 2020

This study aimed to evaluate the efficacy of hyaluronic acid/trehalose drop for corneal epithelial and stromal healing after phacoemulsification surgery at Maltepe University, Department of Ophthalmology, Istanbul, Turkey. It is a retrospective randomized comparative study.The patients had phacoemulsification surgery divided into two groups. These patients received either a mixture of sodium hyaluronate and trehalose (HT, Thealoz Duo®, Thea)(Group 1) or sodium hyaluronate 0.15% (Eye Still®; Teka) (Group 2) postoperatively. Effect on corneal epithelial and stromal healing was evaluated using Oxford staining and the vertical scar length measured by optic coherence tomography (OCT) respectively. Preoperative and postoperative findings for Oxford staining, Schirmer’s test, tear film break-uptime (TBUT) and ocular surface disease index(OSDI) scores were also evaluated. The correlation between scar length and tear film parameters was examined. The effect of trehalose on the epithelial healing and stromal scar formation was evaluated. Group 1 and 2 each had 30 eyes. The two groups were similar according to age and sex distribution. In terms of epithelial healing, it was faster in the trehalose group, although there was no statistical difference between the two groups. The length of the stromal scar was not significantly different between groups, though a smaller scar formation was observed in group 1 compared to those in group 2 at both 1 week and 1 month postoperatively. There was also no significant difference between the groups in tear film parameters. The stromal scar length was correlated with the Schirmer test on the 15th day. Although it was not statistically significant, the hyaluronic acid/trehalose may affect epithelial healing and stromal scar formation in a positive way after phacoemulsification surgery. Larger and longer studies are needed.
