The European conger eel Conger conger represents an important economic resource. Previous studies have provided some information about the biometry of C. conger. This paper presents the first research on biometrical parameters and biological indices of this species in Tunisia. Our sample includes 353 specimens, among them 66.57% females, 32.29% of undetermined sex and only 1.13% males. The length and weight of specimens ranged from 25.5 to 135 cm and from 17.26 to 5087 g, respectively. For the meristic characteristics, the number of pre-pectoral pores was 6, the total number of pre-anal pores ranged between 44 and 47 and the total number of vertebrae varied between 148 and 154. Five allometric relationships were examined. The comparisons of slope and intercept show differences between individuals of determined sex (males and females grouped) and those of undetermined sex. Analysis of the weight-length relationship showed a positive allometric growth. Our data provided the first investigation on the seasonal variation of three bio-physiological indices ; the condition factor does not show variations among seasons, the gonadosomatic index variation reinforces the hypothesis that sexual maturation of C. conger females occurs during the migration from coastal waters towards spawning areas in the deep sea and the hepatosomatic index was highest in spring for females. Since C. conger is widely distributed in the Mediterranean Sea and the Atlantic Ocean, our contribution allows useful comparisons and clarifies the morphological and bio-physiological aspects of this species.

Published: February 2021

Iran lies within three major phytogeographical regions including the Euro-Siberian, Irano-Turanian and Saharo-Sindian regions. There are many microclimates and ecological niches in different parts of the country especially along the transitional and ecotone zones. The Mediterranean xeric oceanic (Mxo) microbioclimate is a noteworthy climatic condition which covers the lowland areas of the Mediterranean basin and surprisingly occurs also in three small patches in Iran, including the Sefid-Rud valley, southern foothills of Khabr Mountain and several valleys of western Jebal-e Barez Mountain range. The latter region is the subject of the present study. Unexpected occurrences of several Mediterranean species such as Cercis siliquastrum, Myrtus communis, Linaria iranica and Melissa officinalis are confirmed from this region and their distributions are briefly discussed in relation to climatic conditions.

Aim.To study the incidence and possible risk factors for atrial fibrillation (AF) in the early postoperative period after transapical implantation of the first domestic aortic valve (TAVI) “MedLab-CT”.

Material and methods.The study included 118 patients after successful TAVI. The study did not include patients with open aortic valve replacement due to dislocation of the prosthesis, with severe intraoperative complications leading to the death of the patient, and patients with permanent AF. The mean age of the patients was 71.1 ± 4.9 years, body mass index was 31.1 ± 5.9 kg/m2, men were 39.8%, hypertension was in 93.2%, diabetes mellitus (DM) was in 27.9%, paroxysmal AF was in 12.7%, coronary heart disease (CHD) was in 56.7%, smoking was noted in 8.4% cases. The median follow-up time corresponded to the hospital stay - 9.5 days. To identify cardiac arrhythmias, daily regular ECG recordings in 12 leads were assessed from the first day after TAVI. In the presence of palpitations, 24-hour ECG monitoring was performed. Indicators such as age, male gender, DM, history of AF, interatrial block before surgery, CHD, and echocardiographic parameters were studied as possible predictors of AF development in the early postoperative period after TAVI. There were no significant differences in the studied parameters in patients with AF paroxysms and sinus rhythm.

Results.In the early postoperative period, AF episodess occurred in 46 (39%) patients. New-onset AF occurred in 38 (32.2%) patients. The only statistically significant risk factor for AF in the postoperative period in our series of observations was CHD (OR 5.756; 95% CI 1.009-8.132; p = 0.048).

Conclusion.Patients with paroxysmal AF in the early postoperative period were not detected cerebrovascular events. In the early postoperative period, the only significant predictor of AF was the presence of proven CHD in patients.

On the Properties of Two-Dimensional Normalized Boubaker Polynomials
Authors: Sarhan Mohammed Abdelhadi , Shihab Suha , Rasheed Mohammed
Published: February 2021

The aim of the present work deals with newly defined two-variable polynomials for normalized Boubaker . The operational matrices of derivatives with respect to the two variables are presented at first with explicit expression. Then, a normalized Boubaker polynomial approximation for the numerical solution of a class of partial differential equations is proposed, depending on a truncated, normalized Boubaker function series in the equation together with the operational matrices in the proposed partial differential equation. The original partial differential equation is reduced under consideration of a system of simply solvable algebraic equations. Due to the interesting derived properties of normalized Boubaker polynomials in two variables, the suggested method can achieve good results with few complexities. Using operational matrices of derivatives, one can save computation and more memory. Two-dimensional examples are listed to show the satisfactory level of the suggested method.

Published: February 2021

This paper aims to establish a research model of knowledge sharing in the public sector and attempts to explain why some public organizations can benefit from knowledge sharing while others cannot. The antecedents of knowledge sharing in the model consist of attitude, public service motivation, organizational social capital, workplace friendship, and team culture. Based on a survey of 343 managers of public organizations in Southern Vietnam, the results illustrate that attitude toward knowledge sharing, organizational social capital, and workplace friendship significantly influence knowledge sharing. By contrast, there is no evidence supporting direct impacts of public service motivation and team culture on knowledge sharing. The study also highlights some theoretical contributions and makes specific recommendations for motivating public servants to participate in knowledge sharing activities.

Published: February 2021

In this paper, we propose an efficient approximate indirect method for solving problems in calculus of variational. First, we introduce orthonormal Boubaker polynomials along with their important properties. These properties are employed to derive a general expansion of their operational matrices of derivation and integration along with a product operational matrix. The operational matrices are then used to approximate the solution. Finally, such approximations are substituted in the functional and necessary optimal condition, which then transform the variational problem under consideration into an algebraic system. Examples illustrate the validity and accuracy of the presented method.
Citizen Participation Policy Making for Environmental Issues: A Literature Review
Authors: Ghaffari Rahman , Tonkaboni Mahdi Ahmadi
Published: February 2021

Developing countries, like Iran, have challenging environmental problems – the need to improve the state of the environment, for human beings and other living creatures, is among the most serious challenges for comprehensive development in such countries. Governments and local organizations could not single-handedly tackle the destruction, and its associated problems in the environment. Consequently, the value and role of public participation in administrating nations and developing democratic societies has drawn attention to the idea of citizen participation in management. Involvement of citizens in environmental issues is considered as one of the key realms of governmental strategic planning. Lack of systematic knowledge and sufficient awareness among officials and major decision makers has become a main source of challenges and problems in this area. This has resulted in a poor assessment of current situations and the consequent inability to provide the best conditions for employing the resources of civic engagement in environmental issues. This research aims to review related studies covering the topic of citizen participation in policy making, with regards to the environment.

Published: February 2021

Parties in the supply chain system that carry out the construction of roads and bridges in Eastern Indonesia from procurement to implementation mainly consist of the owners who represent the community in the upstream and the supervisory consultants, contractors, subcontractors, and suppliers in the downstream. The project proposed in this paper will be successful if the parties carry out the process in an integrated manner according to government regulations. There has been no research on the integration of the parties from the procurement to execution stages. The existing research generally still regards the execution stage. The research objective of this project is to analyze the integration of parties in the supply chain system for the successful execution of road and bridge projects in Eastern Indonesia. To determine whether the integrated practice between parties in the supply chain system can be attributed exclusively to the successful implementation of the project, a questionnaire format was developed. Data collection took place from September 2019 to March 2020. Thirty respondents represented Owners (X1), Contractors and Subcontractors (X2), Supervisory Consultants (X3), and Suppliers (X4), whereas the success of the project’s implementation was represented with (Y). Data were analyzed using multiple linear regression. The analysis result of R-squared = 0.96 means that the parties are significantly integrated. F = 147.92 means that the variant of the regression model is good. P-value or significance F < 0.05 means that the parties’ integration is very significant for the project’s success.
Lifting Wavelet Transform in Compressive Sensing for MRI Reconstruction

Published: February 2021

Compressed sampling in the application of magnetic resonance imaging compression requires high accuracy when reconstructing from a small number of samples. Sparsity in magnetic resonance images is a fundamental requirement in compressed sampling. In this paper, we proposed the lifting wavelet transform sparsity technique by taking wavelet coefficients on the low pass sub-band that contains meaningful information. The application of novel methods useful for compressing data with the highest compression ratio at the sender but still maintaining high accuracy at the receiver. These wavelet coefficient values are arranged to form a sparse vector. We explore the performance of the proposed method by testing at several levels of lifting wavelet transform decomposition, include Levels 2, 3, 4, 5, and 6. The second requirement for compressed sampling is the acquisition technique. The data sampled sparse vectors using a normal distributed random measurement matrix. This matrix is normalized to the average energy of the image pixel block. The last compressed sampling requirement is a reconstruction algorithm. In this study, we analyze three reconstruction algorithms, namely Level 1 magic, iteratively reweighted least squares, and orthogonal matching pursuit, based on structural similarity index measured and peak signal to noise ratio metrics. Experimental results show that magnetic resonance imaging can be reconstructed with higher structural similarity index measured and peak signal to noise ratio using the lifting wavelet transform sparsity technique at a minimum decomposition level of 4. The proposed lifting wavelet transforms and Level 1 magic reconstruction algorithm has the best performance compared to the others at the measurement rate range between 10 to 70. This method also outperforms the techniques in previous studies.

Published: February 2021

The gas production and processing unit's construction plan in the Jambaran-Tiung Biru Gas Plant project is within the Upstream Glonggong River catchment area. Planning arrangement of the Jambaran-Tiung Biru Gas Plant right above the Upstream Glonggong River will impact the disruption of the river's flow and function. Therefore, some of the Upstream Glonggong River segments need to be relocated so that the river's existence and function will not be disturbed. This research aims to find the best alternative in relocating the Upstream Glonggong River. The research method is carried out through hydrological and hydraulic calculations. The selection of relocation alternative of the Upstream Glonggong River was carried out using nine criteria weighting method. The selection criteria for river relocation alternatives used are: 1) upstream channel bottom elevation, 2) channel bottom width, 3) water level, 4) freeboard, 5) channel height, 6) gas plan facility elevation, 7) supporting buildings, and 8) mitigation and risk. The analysis result shows that the alternative selection analysis based on nine criteria assessment indicate that Alternative II (gas plan facility elevation +60.00 m, upstream channel bottom elevation +58.40 m, channel bottom width 6 m, drop structure, retention pond, and overflow) is the best relocation alternative of the Upstream Glonggong River for the construction plan of the gas plan facility in Jambaran Tiung Biru.
Esperienza tragica come iniziazione secondo Lev Sestov (1866-1938)
Authors: Posacki Aleksander
Published: February 2021

Lev Isakovic Sestov e annoverato fra gli eccezionali filosofi del XX secolo. Questo pensatore di origine giudea, e un continuatore della corrente esistenziale del pensiero religioso di Pascal e Kierkegaard
(filosofia della religione). Viene, pero annoverato pure - del resto insieme ai filosofi menzionati - alla corrente del pensiero tragico (antropologia filosofica). Questo non e contradditorio perche ambedue le trame
sono presenti alla riflessione di Sestov, anzi esse sono Ii, cosi inseparabilmente intrecciate, che fino ad oggi la riflessione del pensatore russo essenzialmente sfugge da ogni interpretazione univoca. Nel frammento seguente del teste sto dimostrando che per Sestov l'esperienza tragica non e soltanto un inizio deU'esperienza religiosa, ma anche la sua condizione indispensabile, come un'IIniziazione. Sestov cerca l'esemplificazione di questa coincidenza particolare - l'esperienza tragica come un'iniziazione religiosa - sugli esempi dei vari pensatori di cui ha scrutato non soltanto le opere ma anche le biografie, partendo dalla premessa che esse sono delle realta collegate inseparabilmente. Sestov cerca l'affermazione di questa verita studiando la vita e le opere dei pensatori non soltanto tragici come Shakespeare, Ibsen, Nietzsche o Dostoevskij, ma sopratutto dei pensatori religiosi come Pascal o Lutero e Kierkegaard. In questi ultimi quel collegamento del tragico e della reiigiosita si e fatto evidente, mentre negli altri esso era soltanto parziale e embrionale.

Die ideologischen Scheidewege des modernen Polen
Authors: Ślipko Tadeusz
Published: February 2021

Wenn man das Bild eines modernen Polen aufzeichnen will, dann scheint es sinnvoll zu sein, aufzuzeigen, welche Einstellung ein modemer Durchschnittspole zu drei gesellschaftlich-moralischen Werten hat: zu der persönlichen Würde, zu der Wahrheit, zum Eigentum und zur Arbeit. 

Es ist allgemein bekannt, daß in der Nachkriegsgeschichte unseres Volkes das Jahr 1989 eine deutliche Zäsur darstellt: das 45 Jahre lang unbeschränkt herrschende kommunistische Regime wurde gestürzt, und an seiner Stelle wurde die liberal-demokratische Gesellschaftsordnung eingeführt. Das war kein ausschließlich ökonomisch-politisches Ereignis, Auch das weltanschaulich-ideologische Klima der polnischen Kultur und
Wissenschaft hat eine radikale Veränderung erfahren. Unbestreitbar ist für dieses Klima ein allgemeines Merkmal charakteristisch: uneingeschränkte Gedanken- und Redefreiheit. In dieser Hinsicht stehen die
zwei Epochen i n diametralem Gegensatz zueinander. So ist es nicht verwunderlich, wenn das Bild des modernen Polen Züge sowohl „des Polen der kommunistischer Zeit" als auch „des Polen der  postkommunistischen Zeit" aufweist.
Ruch przestrzenny jako stan
Authors: Ziemiański Stanisław
Published: February 2021

The problem of change has been solved in the philosophical systems threefold: in the radical statism, in the radical variabilism and in the moderate systems. Statism follows the rationalistic theory of knowing,
variabilism - the empiricistic one. The systems combining both, rationalism and empiricism try to reconcile statism and variabilism in diferent ways. E.g. Aristotle solved the problem within his theory of
potency and act. In his opinion the arts and species are stable, the individuals are variable. Stagirite has construed a complete theory of change. Unfortunately, his theory laboured under a misconception
because of including the local movement among the changes. That was a reason why i n the system of Aristotle there appeared many antinomies. Specifically: While all the changes tend to a limit, the local movement has no limit. This fact is peculiarly evident i n the „most perfect" form of movement, the circular. While the limit of change is more perfect than its beginning, no place is more perfect than the other place occupied by a moving thing. Changes occur between the contraries, the places are not contrary.

Stanisław Kowalczyk. Wolność naturą i prawem człowieka, Indywidualny i społeczny wymiar wolności [Freedom - A Human's Nature and One's Right. The Individual and Social Aspects of Freedom]
Authors: Wargacki Stanisław A.
Published: February 2021

The book by professor Stanisław Kowalczyk, renowned scholar in the field of social philosophy, is, without doubt, one of the most important studies on the idea of freedom. The concept of freedom is as old as mankind. It has many meanings and has been interpreted in many different ways. For instance, we also have the word „liberty," which means „freedom or right" and is synonymous with the word freedom, which means „the condition of being free." The author indicates that in our times the notion of freedom is most frequently used; however, it is often misused or deceptive. Mass media and people of all walks of life talk of liberty; everyone talks of freedom and, for many, it is the highest value. Longing for freedom is rooted in the heart of every human being, for freedom is an existential correlate and the fulfilment of the rational human being. The semantic confusion about the notion of freedom leads to many misuses of the concept. Personalism, as a philosophical concept in which a person stands in the centre of all discussion, serves as a framework for the author's delineation on the concept of freedom. He further states that the appropriate understanding of this value is possible in the context of the personalistic interpretation of a human being. This is the focus of this informative and insightful book.

Published: February 2021

В условиях интенсивного развития новых отечественных и зарубежных технологий, материалов и оборудования, применяемых для защиты окружающей природной среды от загрязнений техногенного происхождения, особую актуальность приобретают разработки новых систем отвода и очистки поверхностных сточных вод. Эти системы позволяют использовать последние достижения отраслевой науки и оптимизировать алгоритм выполнения операций и практических приемов их гидравлического расчета. Примером является инновационная система отвода поверхностных сточных вод АСО Qmax, которая относится к открытой системе каналов (лотков) для сбора и отведения поверхностных сточных вод, формирующихся при выпадении атмосферных осадков. Однако широкому применению данного вида конструкций в России препятствует отсутствие методики их гидравлического расчета, в том числе таблиц для подбора сечений (диаметров) каналов, которая бы удовлетворяла требованиям российской нормативно-методической базы проектирования систем отведения поверхностных сточных вод. В этой связи предметом данной статьи явилась оценка гидравлических характеристик трубопроводов, каналов (лотков) системы водоотвода АСО Qmax. Приведены результаты теоретических и экспериментальных исследований гидравлических характеристик системы АСО Qmaxс учетом адаптации для российских условий и нормативных требований, а также обоснование рекомендуемых параметров для их использования.

In the context of the intensive development of new domestic and foreign technologies, materials and equipment used to protect the environment from anthropogenic pollution, the development of advanced systems for surface runoff removal and treatment is of special actuality. These systems provide for using the latest achievements of the sectoral science and optimizing the algorithm for performing operations and practical methods for the hydraulic calculations. An example of the innovative surface runoff disposal system is ASO Qmax, that refers to an open system of channels for the collection and disposal of surface runoff formed during precipitation. However, the widespread use of these facilities in Russia is hampered by the lack of a method for the hydraulic calculations, including tables for the selection of cross-sections (diameters) of channels that meet the requirements of the Russian guidelines and regulations for the design of surface runoff disposal systems. In this regard, the subject of this paper is the estimation of the hydraulic characteristics of pipelines, channels of ASO Qmax drainage system. The results of theoretical and experimental studies of the hydraulic characteristics of ASO Qmax system with account of the adaptation for the Russian conditions and regulatory requirements, as well as the justification of the recommended parameters for their use are presented.
From Emergency Shelter towards Disaster-relief Housing — Tōhoku’s Reconstruction Case Study
Authors: Cosson Camille
Published: February 2021

This paper presents the post-disaster reconstruction of the Tōhoku region. Although Japan has always been one of the most prepared countries because of its long history with natural disasters, the 2011 Great East Japanese Earthquake and tsunami might be one of the most significant disasters recorded in the country’s modern history. This unprecedented disaster that has shaken Japan is a decisive turning point for the entire society as well as for architects and urban planners. Almost ten years later, reconstruction work is still ongoing. This paper introduces specifically Japanese architects’ involvement during the three phases of recovery: emergency shelter, temporary accommodation and permanent housing. After the first stage of perplexity and doubt, architects gradually stepped up and started initiatives to resolve the disaster victims’ precarious situation. This article outlines some of the architects’ actions through the three phases of recovery since the 3.11 disaster. Each of these temporalities has its issues and challenges which the urban planners, architects and designers tried to solve using their know-how to help rebuild devastated communities.
Society of Workers’ Housing Estates and its attempt to overcome the residential crisis in interwar Poland
Authors: Frejtag Jakub
Published: February 2021

After the Great War, one of the most challenging obstacles of the newly recreated Polish state was to ensure residential space for the group of citizens most vulnerable to exclusion. Labourers indeed required an inexpensive and modest habitations maintaining modern sanitary standards. Such facilities were underrepresented in Poland at that time. Mostly overpriced and unsanitary flats were offered in 19th-century housing. Also new housing, although with all modern amenities, did not provide flats with parameters that could meet the expectations of the least wealthy of labourers. In such circumstances, at the end of 1934, a new state-owned company was created – the Society of Workers’ Housing Estate (Towarzystwo Osiedli Robotniczych). Its aim was to build and grant loans for the construction of residential areas with flats meeting the needs of the lower-class labourers. Despite the difficulties, up to 1939, thousands of new flats were built under the Society’s initiative. All these investments exemplify a successful and far-reaching social policy of Second Polish Republic that made residential crisis manageable.

Leakage current analysis on 50 nm thick ferroelectric Al0.78Sc0.22N films with TiN electrodes has been performed. The electron conduction followed Schottky emission with an initial Schottky barrier height (ϕ
B) of 0.46 eV. During the initial switching, a gradual shift in the leakage current was observed, changing the ϕ
B to 0.36 eV, and stayed constant for further switching cycles. From the extracted Richardson constant, the change in the ϕ
B can be interpreted as the formation of a tunneling barrier due to the formation of nitrogen vacancies at the metal interface.

Extreme ultraviolet lithography in high-volume manufacturing requires a longer pellicle lifetime; however, the thermal deformation of pellicles due to repeated exposure can shorten the pellicle lifetime. Thermal stress is used as an indicator in most studies to predict the pellicle lifetime, but because the material can break under low thermal stress depending on the mechanical properties, evaluation of thermomechanical stability including thermal stress and mechanical durability is required. In this study, the thermal stress and mechanical stability of pellicles were evaluated through a comparative analysis of crack occurrence points resulting from thermal deformation for various pellicle structures and contaminant particles. The results show that the thermal stress was lower and the crack time was relatively longer for the metal silicide-based material compared with other pellicle structures. Moreover, it was found that the presence of contaminant particles could be the main cause of pellicle breakage.

Various socio-demographic factors like husband education, residence and occupation were significantly associated (p<0.05) with number of ANC visits. It was also found that factors like motivation for ANC and type of delivery were also significantly associated (p<0.05) with number of ANC visits. Conclusions: It was concluded from the present study that number of ANC visits is significantly associated with socio-demographic and other factors.
A CLINICAL STUDY TO EVALUATE EFFECT OF KSHEERBALA TAILA NASYA IN THE MANAGEMENT OF AVABAHUK w.s.r. FROZEN SHOULDER
Authors: Ghore Jaya K.
Published: February 2021

Avabahuk is the disease that usually affect Amsa sandhi (shoulder joint).. Even though the term Avabahuk is not mentioned in the nanatmaj Vatavyadhi. Acharya Sushrut and others have considered Avabahuk as a Vatajvikar. Avabahuk is one such disease which hampers the day to day activity of an individual.. In Avabahuk, vitiated vata dosha localizes in amsa pradesh and does the sankoch of siras leading to the manifestation1. Sira sankoch and bahupraspanditharam can be correlated with painful stiffness and loss of motion of the shoulder. Hence it can be correlated with frozen shoulder as described in the modern system of medicine.Frozen shoulder is more common in diabetics.
The general line of treatment mentioned for vatavyadhi in ayurvedic classics include snehan (both internal and external), swedan, mrudusamshodhan, basti, shirobasti, Nasya . Acharya Charak further states that, depending on the location and dushya (tissue element vitiated by vata) each patient should be given specific therapies. Acharya Vagbhata has mentioned Nasya karma in the jatruurdhwavatavikaras.
Present study was conducted to assess the efficacy of Nasya with Ksheerbala taila in Avbahuka 15 patients of avabahuka were taken in an open label single group clinical study for nasya with ksheerbalataila.Results of this study showed that Nasya with Ksheerbala taila was effective in relieving the symptoms of Avabahuka and found statistically significant.

Iliac artery occlusions can produce Chronic limb-threatening ischemia and these patients need early revascularization procedures for their limb salvage which is usually established by Aorto-unifemoral bypass. But in patients with poor general conditions femoro-femoral crossover bypass is an alternate option. Ours is Comparative study of Femoro-femoral crossover bypass and Aorto-unifemoral bypass in patients with Iliac occlusion and Chronic limb-threatening ischemia. Total of 22 patients were included in which femorofemoral bypass performed in 10 patients and Aorto-unifemoral bypass in 12 patients. Indications for femorofemoral bypass were poor cardiac/respiratory functions and old age with poor performance. Stable patients were subjected to Aorto-unifemoral bypass. Patency rates and limb salvage rate were 100% with no perioperative mortality in both of these procedures. This shows femorofemoral bypass is an effective revascularization procedure in patients with Iliac occlusion and Chronic limb-threatening ischemia with associated poor general conditions.
