Abstract

Background
Few reports have addressed the clinical and laboratory features of patients with coronavirus disease-2019 (COVID-19) in mountainous areas, especially in Iran.

Objectives
To report the clinical and laboratory data and manifestations predicting mortality of patients with COVID-19 in the west of Iran.

Methods
We conducted a retrospective cohort study of 286 patients hospitalized with COVID-19 between 25 February 2020 and 12 May 2020 to describe their clinical symptoms and laboratory test findings when they were admitted at the Hajar Hospital affiliated with the Shahrekord University of Medical Sciences, and a multivariable analysis of factors that predict their disease severity and mortality.

Results
After hospital admission, 18 patients died and 268 were discharged. Older age [odds ratio (OR) = 1.02, 95% confidence interval (CI) = 1.01–1.04, P = 0.001], presence of underlying diseases (OR = 1.86, 95% CI = 1.01–3.45, P = 0.04), elevated hematocrit (OR = 1.08, 95% CI = 1.03–1.13, P = 0.002), and increase in red blood cell distribution width (RDW) coefficient of variation (OR = 1.18, 95% CI = 1.02–1.36, P = 0.02) were significantly associated with disease severity. Older age (OR = 1.00, 95% CI = 1.00–1.07, P = 0.03), hypocalcemia (OR = 0.20, 95% CI = 0.09–0.58, P = 0.002), hypophosphatemia (OR = 0.50, 95% CI = 0.26–1.02, P = 0.04), and increase in platelet-larger cell ratio (P-LCR; OR = 1.10, 95% CI = 1.00–1.15, P = 0.04) were significantly associated with mortality. The areas under the receiver operating characteristic curves were as follows: calcium 0.759; lactate dehydrogenase (LDH) 0.731; phosphorus 0.725; bilirubin 0.689; C-reactive protein 0.679; and RDW – standard deviation (RDW-SD) 0.624.

Conclusions
Those who did not survive tended to be elderly and had a greater incidence of comorbidities. Elevated LDH, decreased levels of calcium and phosphorus, and anemia at diagnosis were associated with greater risk of death for these Iranian patients hospitalized with COVID-19. Regular assessment of these markers would help to manage patients with COVID-19.
Sustainable agricultural practices adoption

Published: March 2022

Abstract
As it has been practiced for many decades, agriculture has had a significant negative impact on the environment. More land, fertiliser, and pesticides had been used to increase the yield to meet the demands of an expanding population. Consequences included deforestation and soil degradation as well as the extinction of biodiversity, irrigation issues, and pollution, among other things. This has resulted in developing a new type of agriculture known as sustainable agriculture to remedy the situation. Specifically, the goal is to “meet the food and textile needs of society in the present without risking the ability of future generations to meet their own needs.” Using appropriate agricultural practices to implement sustainable agriculture is the most effective method of accomplishing this goal. According to research, farmers’ decisions to effectively adopt sustainable agricultural practices are influenced by a variety of factors. In this paper, we firstly give an overview of sustainable agriculture practices. Then, we review the various factors affecting the adoption of these practices, and finally, we highlight the gap found in the literature.

Published: March 2022

Abstract

EQ-algebras were introduced by Novák in [14] as an algebraic structure of truth values for fuzzy type theory (FFT). In [1], Borzooei et. al. introduced the notion of preideal in bounded EQ-algebras. In this paper, we introduce various kinds of preideals on bounded EQ-algebras such as Λ-prime, ⊗-prime, ∩-prime, ∩-irreducible, maximal and then we investigate some properties and the relations among them. Specially, we prove that in a prelinear and involutive bounded EQ-algebra, any proper preideal is included in a Λ-prime preideal. In the following, we show that the set of all Λ-prime preideals in a bounded EQ-algebra is a T
0 space and under some conditions, it is compact, connected, and Hausdor. Moreover, we show that the set of all maximal preideals of a prelinear involutive bounded EQ-algebra is an Uryshon (Hausdor) space and for a finite EQ-algebra, it is T
3 and T
4 space. Finally, we introduce a contravariant functor from the categories of bounded EQ-algebras to the category of topological spaces.

Published: March 2022

Abstract
A one to one correspondence between the elements of a finite local Frobenius non-chain ring of length 5 and nilpotency index 4, and k-tuples of DNA codewords is established. Using this map the structure of DNA codes over these rings is determined, the length of the code is relatively prime to the characteristic of the residue field of the ring.

Generating punctured surface triangulations with degree at least 4
Authors: Chávez María-José , Negami Seiya , Quintero Antonio , Villar-Liñán María Trinidad 
Published: March 2022

Abstract
As a sequel of a previous paper by the authors, we present here a generating theorem for the family of triangulations of an arbitrary punctured surface with vertex degree ≥ 4. The method is based on a series of reversible operations termed reductions which lead to a minimal set of triangulations in such a way that all intermediate triangulations throughout the reduction process remain within the family. Besides contractible edges and octahedra, the reduction operations act on two new configurations near the surface boundary named quasi-octahedra and N-components. It is also observed that another configuration called M-component remains unaltered under any sequence of reduction operations. We show that one gets rid of M-components by flipping appropriate edges.

Abstract
In this study, we use complementary and sensitive experimental techniques XPS (X-rays Photoelectron Spectroscopy), AES (Auger Electron Spectroscopy, REELS (Reflection Electron Energy-Loss Spectroscopy) and PL (photoluminescence) to investigate and compare the chemical, structure, electronic and optical properties of Un-doped ZnO (UZO) and Indium-doped ZnO (IZO) (4% In; 6% In) thin films. Spray method is used for the growth of these thin films on Si substrate. A treatment process UHV (Ultra-High -Vacuum: Ar+ sputtering followed by checked successive heating until 650°C) is performed. XPS and AES results allow to confirm the clean state of samples and the incorporation of indium into the ZnO matrix to form chemical species of (In-O-Zn) type. The recorded REELS spectra at different primary energies and the PL measurements justify that the UHV treatment plays an important role to improve the physical structure of IZO (6% In).

Authors: Pruteanu Marian , Entuc Ioana-Sorina , Isopescu Dorina Nicolina , Oprisan Gabriel , Bagdasar Laurentiu Cristinel 
Published: March 2022

Abstract
Concrete is a building material with a continuous demand in the construction industry due to the convenient price-performance ratio. On the other hand, concrete is not an environmentally friendly material. Thus, in order to obtain a sustainable material, wood waste can be recycled and used as light aggregates in the manufacture of precast ecological building blocks. Block walls must satisfy not only structural criteria but also functional requirements. In addition, thermal contribution is important in reducing energy consumption over the life of the building. The presence of moisture on the exterior walls due to the appearance of condensation will decrease the thermal performance of building materials. This paper analyses the occurring of condensation risk and its location in the outer wall made of wood-concrete blocks by the Glaser method, for different situations of arrangement and composition of the layers.
Passive Strategies of Vernacular Architecture for Energy Efficiency
Authors: Cojocaru Alexandra , Isopescu Dorina Nicolina 
Published: March 2022

Abstract
Due to the need of sustainable development of the building sector, it is important to increase the energy efficiency in buildings and reduce the energy consumption for heating and cooling. In a changing world, full of innovative solutions and technologies, passive strategies of vernacular architecture are more used to achieve life quality and eliminate the negative impact on the environment and human health.
The vernacular architecture is based on the local construction materials and influenced by the traditions, culture and climate of the place. The “architecture without architect”, used mainly in housing, evolves over time and reflects the level of technology and historical context of the building. The core of this type of buildings was to use architecture to collect free energy from natural environment.
Demonstrated over time, the inherent and timeless knowledge of vernacular architecture offers the basic level of comfortable living without the active strategies that include technologies. Passive architecture strategies are defined by minimizing or avoiding the energy consumption, using architecture and the natural environment to produce heating, cooling, ventilation and light. The elements of the natural environment are the sources of the energy: the sun, the earth, the air – the wind, the water. By adding active technologies, the quality of living must increase, but without influencing the main resources gained through passive strategies.
The present paper will provide the information needed to understand the importance of the vernacular architecture’s passive strategies, as well as describe a few examples of those strategies in different parts of the world, examples that demonstrate the efficiency and the impact of these systems. The authors state that the use of those strategies in the first stage of architecture design helps to achieve easier the energy efficiency required nowadays and represents the fundamental base for passive houses and nearly zero energy buildings.
Adaptive Architecture – A Beneficial Interaction with Technology
Authors: Dohotariu Ionuț 
Published: March 2022

Abstract
The implementation of the cutting-edge technologies - related to communication and information transfer, as well as those related to intelligent materials, sensors, components and modules represent the only plausible way towards the emergence of complex, autonomous and decentralized systems of adaptation. The adaptive architecture deals with buildings designed to adjust dynamically to the environment, inhabitants and contained objects, its behaviour being influenced by the response of the users and the environment. The author highlights the innovations and adaptive capacities currently available by critically examining the specialized literature, by showing the philosophy behind the design of adaptive architecture - the direct involvement of the user in the act of designing and personalizing the adaptive architectural space, a continuous optimization process, in real time, by using it. The research results indicate that the emergence of adaptive architecture is based on the continuous cultural and technological remodelling of the contemporary ethos; the built environment influences the cognitive level, the emotions, the mental and physical well-being. The processual dimension, conferred by technology, allows for the possibility of manifesting an autonomous behaviour, capable of alternating the organization of the space, thus outlining a framework well suited to user’s searches.
Autonomous Processes in Concrete Matrix on Bio Products
Authors: Sbîrlea Cătălin , Isopescu Dorina Nicolina 
Published: March 2022

Abstract
In this paper are presented different approaches of microbiological type, on the concrete matrix, that has the ability to self-healing the micro-cracks in their early phase. Although the prevention of cracks in the concrete structure is not possible, there are many types of techniques that will lead to self-sealing. Thereby we can say the cracks represent the biggest enemy of the elements in the constructions, and if they are not observed and treated in the early phase, they can create real dangers, both for the constructions and for the people. The micro-cracks appeared in the concrete matrix are determined by a number of internal and / or external factors. The determination of the cause of the appearance of the micro-cracks is done by visual inspections and by direct measurements, using special equipment. The identification of the various biological compounds and their use in autonomous processes can represent a sustainable but also efficient alternative on the costs of concrete production. From the researchers’ reports, the application of chemicals and polymers represents a source of risks for human health, plus the fact that these methods are viable in the short term.
The bio products exemplified in this paper are found in nature, are human friendly, and through the information provided by the researchers we can say that they increase the life of the construction. An important feature of the use of organic products in the concrete matrix is the fact that the concrete can self-healing, only needing water and oxygen. The two approaches of autonomous type presented in this paper are similar in terms of the result obtained but different from the point of view of the healing agents used. This paper will provide an overview of the bio approach through the production of calcium carbonate, will present the new challenges for sealing the micro-cracks and recommendations for future research.

Published: March 2022

Abstract
This paper focuses on modelling of the flexible loads of a residential area, based on a classification of eligible appliances. Thus, in order to use the photovoltaic energy with a higher efficiency, the methods of traditional load management are involved in residential sector in order to ensure an optimal balance between demanded load and photovoltaic generated power. The concept of Home Energy Management System is an action taken by the consumer and it is part of the concept for Demand Load Management. The most important thing in implementation of this algorithm is to perform a classification of the electrical appliances. Using the Matlab simulation, in this paper has been generated a consumption load profile based on a list of appliances specific to residential area. Based on generated load profile, in the paper has been extracted in several graphs, the power of the equipment that supports and does not support changes in the operating program. Previously, a classification of these appliances has been conducted, the most important aspect taken into account in their classification being the minimum impact on the user’s comfort.
The Role of Dielectrophoresis in the Detection and Separation of Circulating Tumor Cells
Authors: Schreiner Thomas Gabriel , Adam Maricel 
Published: March 2022

Abstract
Dielectrophoresis (DEP) is a method of manipulating, including separating, of target object (nano and/or microparticles, living cells) in the presence of a non-uniform electric field. In recent years, the method has found numerous applications in the bio-medical fields, especially in oncology, more precisely in the study of circulating tumor cells (CTCs). CTCs are cells released by a tumor during its early stages of metastasis, when secondary tumors cannot yet be detected by classical imaging methods. Thus, DEP may be a useful adjuvant method in the earlier detection of cancer. In this context, this article offers a new perspective on a topic of great interest nowadays. Presenting in the first two parts in detail the technique of DEP and the most important physical-biological characteristics of the CTCs, the article lists in the final part the most relevant and recent applications of this technique in the field of tumor cells, opening possible future research directions.
Prerequisites to Design a Collision Free Trajectory in a 3D Dynamic Environment for an UAV
Authors: Huştiu Sofia 
Published: March 2022

AbstractThis research presents the main steps needed for designing a piece-wise linear trajectory which grants an unmanned aerial vehicle (UAV) to reach a destination pose in a workspace with dynamic obstacles. The first objective is characterized by the examination of kinematics and dynamics of a quadcopter. For this purpose, a nonlinear mathematical model was developed. The validation of the mathematical model was confirmed by MATLAB and real time experiments. The second step aims to properly map the 3D environment. For this objective, an algorithm for a cuboid rectangular decomposition was developed and implemented, by extending a 2D decomposition technique. The evaluation of the proposed path planning algorithm occurred for different scenarios and the validation of the results was established through numerical simulations. In the end, a comparison for two path planning scenarios is shown: for a 3D static environment and for a 3D dynamic environment, where the movement of a dynamic obstacle is known.
Leaving Homeland: The Evolving Conceptualization of Migration in the Iranian Cinema of the 2010s
Authors: Tabarraee Babak 
Published: March 2022

Many of the Iranian films released inside Iran during the 2010s address the latest wave of Iranians’ emigrations since 2009. Examining the dominant tropes of migration in their narrative subsets, this article argues that the Iranian cinema of the last decade offers a paradigm shift in its conceptualization of migration which may reflect a gradual change in Iranian society. This study proposes that while some recent Iranian films have maintained the pre-established traditions of depicting the hosting countries of immigrants on utopic and/or dystopic terms, a high number of movies have instead presented temporary or permanent migration as a natural, self-evident, and righteous choice. Analyzing the representational strategies of these films obfuscates the imagined borders of a global community of Iranians and problematizes the classic definition of farangistan (foreign lands) by lessening its otherness from Iranshahr (the land of Iranians).
