Abstract
The level of access of women to production resources can be enhanced through their active membership and participation in farmers’ associations. However, most farmer-groups in Nigeria are male-dominated. The study therefore analysed women farmers’ participation in farmer-group activities in Kwara State. Specifically, the study identified the expectations of women from group membership; determined their level of participation; identified constraints to participation; and investigated the determinants of participation. A two-stage random sampling technique was used to select 142 women farmers on which a structured interview schedule was administered. Descriptive statistics, Likert scale, and Ordinary Least Square (OLS) Regression Analysis were used to analyse and present the data collected. The results revealed that the mean age, years of experience and farm size of the respondents were 46.9 years, 22 years and 3.2 acres, respectively. Access to farm credit (57 %), self-help (49.4 %), and farm input (31.1 %) were the most important expectations from membership. The level of women participation was low (mean = 2.87) and determined by age, years of experience and farm size at P < 0.05. Financial constraints, poor sense of belonging, inappropriate timing of activities and socio-cultural discrimination were the most severe challenges to participation. The study concluded that women participation in farmer-group activities was low, influenced by their socio-economic characteristics. Therefore, we strongly recommend a multi-dimensional approach to enhance women’s participation in group activities.

Abstract
In this study we analysed the effect of the reward of internal migration on the poverty status of rural households in South-West Nigeria. The types and channels of internal remittances received by rural households as well as the poverty profile and effect of internal remittances on the poverty status of rural households in South-West, Nigeria were assessed. Structured questionnaire was used to obtain primary data from respondents. Data were analysed using descriptive statistics, Multidimensional Poverty Index and Binary Logit regression. Findings revealed that 56.2% of the household heads were male, 67.4% were married, 42.3% had primary education and 58.3% received internal remittances through personal delivery (69%) with a mean age and household size of 55 years and 5 persons, respectively. However, based on Multidimensional Poverty Index benchmark of 0.333, 80.0% of the rural households were poor with a poverty intensity of 0.863. Binary Logit showed that age squared, remittance receipt, rearing of small livestock and farm size increased households’ likelihood of escaping poverty. In conclusion, internal remittances reduced poverty of rural households in the study area and as such continuous flow of remittances into rural households should be enhanced in order to facilitate improved standard of living.
A stop over Jain operators and their generalizations
Authors: Agratini Octavian 
Published: June 2020

Abstract
On the last five decades the interest of the study of positive approximation processes have emerged with growing evidence. A special place is occupied by the in-depth study of classical operators. The most eloquent example is Bernstein operator which represents a permanent challenge for the researches in the mentioned field.
However, in this synthesis we focused on presenting a class of operators introduced by G.C. Jain in the 1970s that have long been in a shadowy cone. In recent years many papers have appeared about their properties and many generalizations have been analyzed. In our approach, there is no question of an exhaustive treatment, but only of collecting some published results that prove the importance of this class through the generous possibilities o ered by the approximation of signals from different function spaces.
Effect of Zn Content on Structure, Roughness and Corrosion Behavior of Zn-Ni Alloys
Authors: Faid Hayette 
Published: June 2020

Abstract
In this work, Zn-Ni alloys have been deposited on steel from sulfate bath, by electrodeposition method. The effect of Zn content on deposits properties was studied by cyclic voltammetry (CV), chronoaperometry (CA), linear stripping voltammetry (ALSV) and diffraction (XRD) and scanning electronic microscopy (SEM). The corrosion behavior in 3.5 wt. NaCl solution was examined using anodic polarization test and electrochemical impedance spectroscopy. X-ray diffraction of show that Zn-Ni alloys structure is composed of δ phase and γ phase, which increase with the decrease of Zn content in deposits. Results show that deposits obtained from bath less Zn2+ concentration exhibited better corrosion resistance.

Critica Literară Românească Din Perspectiva Metodelor De Analiză Autocolonială (1840-1939)
Authors: Morariu David 
Published: June 2020

Abstract
This study aims to analyze the Romanian critical discourses of the second half of the 19th century and especially of the first half of the 20th century, starting from the central concept of “self-colonization”, coined by Alexander Kiossev. The article opens with the conceptual delimiting of the phenomenon imposed by the Bulgarian theoretician and with the hypothesis that Romanian culture can be attributed to self-colonizing cultures. The demonstration of this hypothesis consists of three arguments. The critical discourses belonging to G. Ibrăileanu, E. Lovinescu and C. Dobrogeanu-Gherea highlight, firstly, some of the characteristics of this self-subordination relation. The way the first two emphasize the role of imitation, the necessity of adopting the foreign models and the way Gherea treats the dependence upon the West under an economic report, represent, briefly, the center of the first part of the demonstration. The second one brings to the fore Mihail Kogălniceanu and Titu Maiorescu’s profiles, their discourses being characterized by clumsiness and flaws so typical for a culture found in an early stage of its development. The last argument broadens the scope of the demonstration in the sense that the analysis focuses on social and economic delimiting. The purpose of this delimiting is to establish which are the areas that are more responsive to the manifestation of the self-colonizing phenomenon.
Configurarea Paradigmei Terţului Inclus – Blaga, Bachelard, Lupaşcu1
Authors: Dincă Irina 
Published: June 2020

Abstract
This paper aims to present the connection and continuity between the implicit principles that configure the transgressive visions of Lucian Blaga, Gaston Bachelard and Ștefan Lupașcu, which inaugurate a paradigmatic change in consensus with the revolutionary ideas circulating in science, philosophy, poetry and art across the 20th century. The subtle paradigmatic axis which crosses implicitly or explicitly the work of Lucian Blaga proves to be the transgressive attempt of integration and overcoming of the antinomies under the sign of
the included middle
which underlies the transfiguring core of the
dogmatic paradox
. Thus, the nucleus of Blaga’s epistemological vision, the
dogmatic paradox
– a synthesis of the antinomies solved not in concrete level, but in transcendent one, creating a paradoxical logics – proves to be close to Gaston Bachelard’s transgressive theoretical constructions –
the surrationalism
and
the philosophy of no
–, as well as to Ştefan Lupaşcu’s integrative perspective of
the dynamic logics of the contradictory
. The subtly related nexus of theoretical ideas developed by Blaga, Bachelard and Lupașcu appear to be essential milestones in the avant-garde of the paradigmatic chain of the included middle, opening it towards the present European episteme.
Inocentul Alienat Și DepăȘirea Limitelor (Auto)Impuse
Authors: Merce Gabriela-Emilia 
Published: June 2020

Abstract
The starting point of my work is represented by three of Lucian Blaga’s plays: Daria, Ivanca and Înviere. We tried to show that the characters of these plays represent pieces of individuality and also these characters will be free from their existential drama only if they will become a mirror for the each other, only if they will be interconnected and if these characters will be able to transfer a part of their identity to another individual.
Ipostaze Thanatice În Poetica Lui Lucian Blaga Și Dylan Thomas
Authors: Săran Raul 
Published: June 2020

Abstract
The following paper revolves around the concept of thanatos, whose name comes from the personification of death in the Greek mythology. In other words, the objective of this paper is to analyze the main forms and symbols regarding the theme of death in several poems of Lucian Blaga and Dylan Thomas and try to explain how, despite the fact that they come from different cultural environments and have different sources of inspiration and literary purposes regarding the aim of their works, their poetical works present several resemblances in terms of meaning in relation to the theme of death, as approached in the 20th century modern poetry.
Influenţe Secession În Lirica Blagiană
Authors: Frătean Denisa-Maria 
Published: June 2020

Abstract
Secession Influences in Blaga’s Poetry (Influențe Secession în lirica blagiană) – This essay analyses the impact of the years spent in Vienna on the formation of Lucian Blaga, taking into consideration the fact that, at the end of the 19th century and the beginning of the 20th century, the capital of the Empire was the centre of an impressive art movement called the "Vienna Secession". The aim of this paper is to identify the similarities that can be established between the art of the painter Gustav Klimt, a representative figure for that period and the president of Secession, and the poetry of Blaga. The comparison includes the symbols to be found in the works of the two artists, such as the spring flowers and the serpents, the dominant colours, the type of lines used in the creation of their images and the reaction of people to their modern art.
Criza Corporalităţii În Poetica Lui Ilarie Voronca
Authors: Foitoș Alexandru 
Published: June 2020

Abstract
The aim of this paper is to highlight the vanguardist poetical universe of Ilarie Voronca, focusing on the construction of corporeal representations. The poetics of corporeality is associated with the concept of “crisis”, the latter being reverberated in the vanguard lyrical works as an effect of the historical and social context of the 20th century, which is the First World War. As a result, the consequences of this context bring to the vanguard writers poetical substance, which encapsulates the body and the disease, these two being transposed into several eerie, radical and shocking images in Ilarie Voronca’s poetics. This paper is going to demonstrate the existence of several corporeal representations in Ilarie Voronca’s poems, which are mainly represented by the
vulnerable body
, viewed as a
limit
and as
the diseased/the suffering
, proving that the crisis of corporeality is the effect of the historical conflagration at the beginning of the 20th century.
Apologia Tăcerii Și A Căutării În Poemul Autoportret
Authors: Batori Andreea-Corina 
Published: June 2020

Abstract
Lucian Blaga is popular among the Romanian writers for his beliefs in the power of the unknown and the unsaid-word, for his attention given to the notion of mystery and knowledge.
The present paper focuses on two of the main elements that coordinate some of the poet’s lyrical writings: silence and the state of being in a continuous search for the initial harmonious relationship with the Universe by returning to the origins of the world, by regeneration and reconstruction. These ideas are emphasized in the poem titled Autoportret in which the soul of the individual find sit self in the these arch for beauty and nothingness, for the pure word which is able to reinforce the bond between the individual and the totality of the unharmed Universe.
Using themes, motifs, symbols, myths, figures of speech and techniques of construction, Lucian Blaga succeeds in creating a representative poem for his last volume entitled Nebănuitele trepte, a poem characterized by expressiveness, depth and a strong wish to find by means of silence what the souls has been looking for since ever – purity, peace and harmony.
Pax Magna Sau Despre Simpatia Demon-Creator

Published: June 2020

Abstract
One of the most representative theme in the works of Lucian Blaga is knowledge and the way it is reflected in the unconscious. He is known for the different meanings given to this knowledge, proposing a new path for the understanding of everything around us, starting from the inner of human soul to the world genesis. This paper will show this specific process of Blaga, in one poem „Pax Magna”.
On Discontinuous Galerkin Methods for Elliptic Problems with Discontinuous Coefficients
Authors: Dryja Maksymilian 
Published: June 2020

AbstractDiscontinuous Galerkin methods for elliptic problems with discontinuous coefficients are discussed. First the error bound of the methods is analyzed. Then
a multilevel additive Schwarz preconditioner for one of the discrete problems is designed and analyzed. Although the preconditioner is not optimal it is very well suited
for parallel computations and its rate of convergence is independent of the jumps of coefficients.
Robust Multigrid Technique for Black Box Software
Authors: Martynenko S.I. 
Published: June 2020

Abstract This paper presents a new robust multigrid technique for solving boundary
value problems in a black box manner. To overcome the problem of robustness,
the technique is based on the incorporation of adaptation of boundary value problems
to numerical methods, control volume discretization and a new multigrid solver into a
united computational algorithm. The special multiple coarse grid correction strategy
makes it possible to obtain problem-independent transfer operators. As a result, most
modes are approximated on coarse grids to make the task of the smoother on the finest
grid the least demanding. A detailed description of the robust multigrid technique and
examples of its application for solving benchmark problems are given in the paper.
Mathematical Modeling of Geofiltration and Geomigration Processes in Multilayer Systems
Authors: Gromyko G. , Chuiko M. , Smychnik A. , Hrechka A. , Zlebava A. 
Published: June 2020

AbstractNumerical methods for simultaneous solution of geofiltration and ge-
omigration problems in multilayer systems in contaminant transport investigation have
been developed. A multilayer system consists of several aquifers separated by weakly
permeable layers. Mathematical models are constructed under the following assump-
tion: longitudinal flows predominate in the aquifer and crossflows — in the separation
layers. The mass transfer is described by the convection and diffusion equations.
The implicit finite volume difference schemes were used. The computational al-
gorithm is based on the concept of splitting the schemes on physical processes of two-
dimensional filtration and contaminant transport along aquifers and vertical transport
through the separation levels.
An iterative method of the block Gauss — Seidel type for the realization of implicit
finite difference schemes for geofiltration and geomigration problems in the presence
of wells and contaminant sources has been constructed. The method is based on the
perturbation transfer from cells with sources (wells and sources of contaminant). The
iterative process for update of unknowns has been constructed taking into account the
position of a cell relative to the calculated cells.
The results of the numerical experiment on modeling groundwater flows redistri-
bution and contaminant migration in system of two aquifers with operating wells are
presented.
Analysis Of Upwind Method For Piecewise Deterministic Markov Processes
Authors: Annunziato M. 
Published: June 2020

AbstractA numerical upscaling approach, NU, for solving multiscale elliptic problems is discussed. The main components of this NU are: i) local solve of aux-iliary problems in grid blocks and formal upscaling of the obtained results to build a coarse scale equation; ii) global solve of the upscaled coarse scale equation; and iii) reconstruction of a fine scale solution by solving local block problems on a dual coarse grid. By its structure NU is similar to other methods for solving multiscale elliptic problems, such as the multiscale finite element method, the multiscale mixed finite element method, the numerical subgrid upscaling method, heterogeneous mul-tiscale method, and the multiscale finite volume method. The difference with those methods is in the way the coarse scale equation is build and solved, and in the way the fine scale solution is reconstructed. Essential components of the presented here NU approach are the formal homogenization in the coarse blocks and the usage of so called multipoint flux approximation method, MPFA. Unlike the usual usage of MPFA as a discretization method for single scale elliptic problems with tensor discontinuous coefficients, we consider its usage as a part of a numerical upscaling approach. An aim of this paper is to compare the performance of NU with the one of MsFEM for ceratin multiscale problems. In particular, it is shown that the resonance effect, which limits the application of the Multiscale FEM, does not appear, or it is significantly relaxed, when the presented here numerical upscaling approach is applied.
Morozov’s Discrepancy Principle For The Tikhonov Regularization Of Exponentially Ill-Posed Problems

Published: June 2020

Abstract The problem of approximate solution of severely ill-posed problems given in the form of linear operator equations
of the first kind with approximately known right-hand sides was considered. We have studied a strategy for solving
this type of problems, which consists in combinating of Morozov’s discrepancy principle and a finite-dimensional
version of the Tikhonov regularization. It is shown that this combination provides an optimal order of accuracy on source sets
Tensor-Train Ranks for Matrices and Their Inverses
Authors: Oseledets Ivan , Tyrtyshnikov Eugene , Zamarashkin Nickolai 
Published: June 2020

Abstract We show that the recent tensor-train (TT) decompositions of matrices come up from its
recursive Kronecker-product representations with a systematic use of common bases. The names
TTM and QTT used in this case stress the relation with multilevel matrices or quantization
that increases artificially the number of levels. Then we investigate how the tensor-train
ranks of a matrix can be related to those of its inverse. In the case of a banded Toeplitz
matrix, we prove that the tensor-train ranks of its inverse are bounded above by 1+(l+u)^2,
where l and u are the bandwidths in the lower and upper parts of the matrix without the main
diagonal.

Published: June 2020

Abstract

Silver fir Abies alba Mill. provenance trials started in Poland a few years after Pavari (1951) proved that the origin of this tree species influences its genetic variability. Further confirmation came from provenance trials, which selected provenances for cultivation in Denmark and showed provenance-dependent genetic variability even within a relatively small area such as the Czech Republic. The Polish trial, started in 1960, compared 6 provenances from the West and Central Carpathian region (4 from Poland, 2 from Slovakia) and 3 from the Hercinic region (Czech Republic). The trial was established in the Experimental Forests of the Warsaw University of Life Sciences in Rogów, at the northern border of the natural silver fir range. Results from the nursery stage experiments proved the existence of latitudinal and altitudinal clines based on data for seed weight, height growth, number of terminal buds as well as bud and needle development. The Polish provenance ‘Stary Sącz’ and two Slovak provenances, ‘Čierný Váh’ and ‘Beňuš’, were early flushing, whereas the Polish provenance ‘Rogów’ behaved differently and was late flushing. Even at the nursery stage, the positive influence of tree selection on height growth and progeny characteristics of the two Czech provenances was evident. The Carpathian provenances were furthermore evaluated according to the index of cultivation and breeding: very good – ‘Rogów’; good ‘ŚPN (Świętokrzyski PN)’, ‘Stary Sącz’ and ‘Skarżysko’; poor – ‘Čierný Váh’ and ‘Beňuš’.
Evaluating the suitability of machinery use during skidding of wood in pine stands
Authors: Szewczyk Katarzyna , Iwanicki Piotr 
Published: June 2020

AbstractSkidding of large-sized logs requires special machinery such as skidders, clambunks, forwarders or farm tractors with a winch or hydraulic tongs. The precise choice of which skidding machine to use depends largely on the desired efficiency and economic factors. The aim of this research was to evaluate the suitability of three different machines (LKT 81 skidder, John Deere 1110D forwarder and Pronar 1221A agricultural tractor with hydraulic tongs) for wood skidding based on technical and economic indicators. The practical work for this research was carried out in the Mirosławiec Forest Division in areas with fresh mixed coniferous forest habitats where the dominant species in the stands was pine and strip-like clear cutting was the preferred management practice.The best machinery performance values were obtained for skidding using the John Deere forwarder.
