Authors: Gayda S.V.
Published: October 2023

It is substantiated that post-consumer wood (PCW) is an additional timber resource for the woodworking industry. It is established that the physical and mechanical parameters of all furniture boards, regardless of their design, satisfy the requirements of regulatory documents. It has been found that the ratio of thickness to the width of the strips is most influenced by the physical and mechanical properties of the furniture boards. The highest physical and mechanical parameters are characterized by a solid furniture boards with a strips cross section of 22×20 mm. The average static bending strength across the strips of such a solid furniture boards is 27.03MPa. The lowest physical and mechanical indicators are characterized by a solid furniture boards with a strips section of 22×80 mm. The average static flexural strength across the strips of such a solid furniture boards is 16.10MPa. The physical-mechanical parameters of a traditional solid furniture boards made of primary wood are slightly higher than the physical-mechanical parameters of a similar solid furniture boards design made of PCW. Thus, the static flexural strength across the strips of a traditional solid furniture boards is 22.05MPa, and the strength of a solid furniture boards made of PCW is 19.88MPa. According to the results of experimental researches it is established that in order to achieve the shape resistance and sufficient strength of the solid furniture boards on a static bend across the strips, it is recommended that the width of the rail for gluing the furniture board should be no more than triple its thickness.

It is recommended to use radial cross-section wooden strips when making solid furniture boards to ensure high resistance. Remodeling the iron on the furniture boards will bring financial and environmental benefits. The financial advantage of the manufacturer is to reduce the material costs of making solid furniture boards made of PCW of iron from the traditional furniture boards. Yes, our calculations show that the cost of solid furniture boards made of PCW is 43.57% depending on the design of the furniture boards. The social and ecological and economic benefit is that by using used wood we reduce by 3 4% the landfill area, reduce deforestation by 0.29 hectares each year, thereby improving the environment.

Development of mathematical models for predicting dimensional stability of furniture boards using the finite element method
Authors: Podibka T.I.
Published: October 2023

An approach for predicting the properties of furniture boards made of common beech wood (Fagus sylvatica L.) based on the finite element method is proposed. It has been found that in the constructions of furniture panels made of beech wood, an orthogonal, cylindrical or transversal calculation scheme of anisotropy can be attributed depending on the dimensions of the furniture panels and the orientation of the fibers in the rails. A model of the physical and mechanical properties of monolithic or jointed slats made of beech wood during the finite element analysis of furniture boards based on the cylindrical coordinate system of the anisotropy of constant elasticity is proposed. It has been established that the practical use of the cylindrical anisotropy scheme when solving the problems of the mechanics of a rigid deformed body for the calculation of furniture boards made of beech wood is expedient when it is not possible to ignore the curvature of the annual layers, that is, when analyzing the dimensional stability of furniture boards and monolithic or jointed reibukaak made of beech wood with swelling and shrinkage. An applied methodology for calculating furniture boards made of beech wood has been developed, which makes it possible to take into account the peculiarities of the anisotropy of the physical and mechanical characteristics of the rails, taking into account their shrinkage and swelling when the temperature and humidity conditions of the environment change. The substantiation of new designs of furniture boards made of beech wood, which is based on the use of finite element analysis systems, allows identifying the shortcomings of these products at the conceptual stage of the project and correcting them before the start of production, taking into account the specified technical conditions. An optimal arrangement scheme of annual layers in adjacent slats of furniture panels made of beech wood is proposed, which ensures improvement of dimensional stability (reduction of gouging) of the structure while simultaneously reducing the stresses that arise when the humidity of the product increases during operation. Mathematical models are proposed that predict (describe) the strength and dimensional stability of furniture boards made of common beech wood. The developed model can be used for research and optimization of furniture boards of new designs according to the conditions of strength and deformability.

A Fast Acting DC-link Voltage Controller for 3-Phase DSTATCOM to Compensate AC & DC Loads
Authors: - A.K.KULKARNI , - M. SEKHAR
Published: October 2023

The transient reaction of the conveyance static compensator (DSTATCOM) is vital while repaying quickly fluctuating uneven and nonlinear burdens. Any adjustment of the heap influences the dc-connect voltage straightforwardly. The unexpected evacuation of burden would bring about an expansion in the dc-connect voltage over the reference esteem, while an abrupt expansion in burden would diminish the dc-interface voltage underneath its reference esteem. The appropriate activity of DSTATCOM requires variety of the dc-connect voltage inside as far as possible. Ordinarily, a relative indispensable (PI) regulator is utilized to keep up with the dc-interface voltage to the reference esteem. It utilizes deviation of the capacitor voltage from its reference esteem as its feedback. Nonetheless, the transient reaction of the ordinary PI dc-connect voltage regulator is slow. In this paper, an effective dc-connect voltage regulator in light of the energy of a dc-interface capacitor is proposed. Numerical conditions are given to process the increases of the traditional regulator in light of effective dc-connect voltage regulators to accomplish comparable quick transient reaction. The nitty gritty reproduction and exploratory investigations are completed to approve the proposed regulator.

Mrs. Thangjam Vs. AFSPA - A Cry in The Dark
Authors: - Romita Roy
Published: October 2023

The Armed Forces (Special Powers) Act (“AFSPA”) has been the subject of several studies which have tried to make sense of its validity, usefulness and moral foundations. Over the course of its existence in several states in the North-East, the powers it has given to Military counterinsurgency operations has not led to the desired outcome it envisioned. Its usefulness in tackling counterinsurgency operations is questionable at best. But the widespread human rights violations it has led to is undeniable.
This paper will attempt to add to the existing scholarship on the possibility of scrapping the Act and removing its operation in North-East India. It will carry out an account of the widespread human rights abuses that have been carried out by the Indian military in the region and will argue that the Act ought to be scrapped altogether because of its failure to adhere to certain normative principles reflecting human dignity and freedom that the state has an obligation to uphold towards its citizens. It will not only analyse the provisions of the Act but will move towards assessing AFSPA in the international legal paradigm in which counterinsurgency is carried out. The paper shall finally conclude by imagining a possibility of allowing the scrapping of the Act which would be beneficial towards State security, the rights of citizens and setting norms for obligations of the State in upholding human rights.

Introduction
Authors: Habibi Negar
Published: October 2023

Iranian kings, or those who reigned in lands under Persian linguistic and cultural domination, followed the idea of a Just Ruler: a pious king who looked after his subjects’ divinity and spirituality in parallel to their earthly lives and needs. The Just Ruler extended righteousness and peace among his people while patronizing the construction of palaces, gardens, and new towns. The idea of a Just Ruler may be found in Sassanid monumental rock reliefs and written texts and then enriched and elaborated upon in the Islamic era by philosophers, poets, authors, and artists. 

This issue of Manazir Journal focuses on how art and architecture served the representation of the Just Ruler in Persianate societies from Central Asia to Eastern Anatolia from the 14th to the 19th centuries. Illustrated books, architecture, and photography show how different kings and rulers referred to the Persian ideas of the Just Ruler by patronizing new constructions, richly illuminated books, and in the modern era, employing mediums such as photography and lithography for nationalizing the king’s image.
Reinvention of Padishah-i Islam in the Visual Representations of Ghazan Khan
Authors: Latifkar Azadeh
Published: October 2023

This article discusses how the visualization of Mahmud Ghazan, the sixth Ilkhanid ruler, was employed to construct and propagate his image as the Padishah-i Islam (King of Islam), thus justifying him both as king of Iranshahr (land of Iran) and the legitimate successor of the Prophet Muhammad. In a quest for visual translations of the Ilkhanid concept of Padishah-i Islam—an inseparable combination of the Persian notion of ideal kingship and prophethood—several illustrations from the Diez albums representing Ghazan or events of his reign have been identified, two of which have become subject to detailed iconographic analyses.
Two approaches to the visualization of Ghazan as Padishah-i Islam can be considered here. The first is Ghazan’s birth scene where the visual narrative is covered in various formal and semantic layers; transformed into a symbolic narrative of a holy birth associated with those of the prophets. The second appears in the scene of Ghazan’s enthronement, probably once illustrated as an unknown manuscript’s frontispiece, the images’ composition and components appear as a visual panegyric poem which applies an elaborate visual language that elevates Ghazan to the level of a divine king.
Samarqand’s Congregational Mosque of Bibi Khanum as a Representation of Timurid Legitimacy and Rulership
Authors: Paskaleva Elena
Published: October 2023

The Bibi Khanum Congregational Mosque is the largest Timurid monument in Samarqand. Commissioned by Timur himself after his military campaign in India in 1399, the architecture of the mosque can be interpreted as a visual representation of Timur’s ambitions to surpass the architectural achievements of the preceding Islamic dynasties. Striving for political legitimacy beyond the legacy of Chinggis Khan, Timur imitated and even exceeded the monumental scale of the architectural ensembles in the Ilkhanid capitals of Tabriz and Sultaniyya. In an attempt to ensure the continuity of the Timurid dynasty, Timur’s successors adopted Yuan iconography and visual vocabulary so as to forge an ancestral and artistic genealogy that directly related the Timurids with the Mongols via the aesthetic legacy of the Ilkhanids and the Yuan. Their cultural production thus secured the continuity of the Timurid royal patrons as just successors of Chinggis Khan.
Sacred King in the Shah Tahmasp Shahnama

Published: October 2023

This paper aims to trace the pre-Islamic Zoroastrian concept of “royal divine glory” (farr) through its visual translations within the Iranian manuscript cultures in the Safavid period, specifically in the illustrations of the Shahnama-yi Shahi in the 16th century. Reviewing the longue durée idea of Iranian kingship perceived within the Safavid royal ideology in the reigns of the first two monarchs, we delve into the Shahnama paintings to see the artists’ assets for showing the divinity and dignity of Iranian kings and how they managed to mark a difference between the profane and Shiite iconographies. We took as case studies nine illustrations of Zahhak’s story, the most tyrannical legendary King in Shah Tahmasp’s Shahnama. Indeed, to analyse the artistic manifestations of the Royal farr, we examined the scenes where the “true” king is literally absent.

Published: October 2023

A protocol for encapsulation of metal nanoparticles with organic shells of porphyrin molecules via silane coupling is described. A strategy with silicon tetrachloride was used to produce a skewered arrangement of porphyrins that are linked through a central silicon atom by siloxane, Si-O-Si bridges. The planar macrocycles align cofacially to surround the periphery of metal nanoparticles (e.g. gold, iron oxide).  Skewered ‘shish kebob’ assemblies of porphyrins form an encapsulating shell by attachment to metal cores with silicon-oxygen-metal bridges. Free-base porphyrins were skewered through siloxane coupling using SiCl4, with the silicon atom inserted to the center of the macrocycles. The Si atom binds to the four nitrogens at the center of the macrocycles, and also links to adjacent macrocycles through siloxane bridges. Iron and gold nanoparticles were used as core materials, while the organic shells were prepared with tetraphenyl porphyrin or octaethyl porphyrin. The thickness of the shells can be tuned by synthetic parameters such as concentration and immersion intervals. Structural changes were tracked using UV/Vis spectroscopy to evaluate spectral shifts. Nanoparticle samples were examined with tapping-mode atomic force microscopy to directly view changes in the size and shapes of nanoparticles before and after encapsulation with porphyrins. Phase images enabled sensitive mapping of the nanoparticle composition, revealing a soft organic shell surrounding the hard metal core. The synthetic approach with skewering porphyrins to metal nanoparticles should be generic for preparing metal core-shell nanoparticles encapsulated with shells of macrocyclic porphyrinoid molecules.

This research investigates the intricacies of impact investing in the hospitality industry and its potential implications for fostering corporate responsibility. The study highlights the pivotal role of impact investing policies in promoting regional economic development and environmental betterment. In the face of pressing global environmental challenges, such as climate change and energy resource scarcity, the study underscores the need for effective measures that positively shape state policy formation. The primary goal of such policy initiatives is to bolster human capital development and ensure the long-term realization of strategic objectives. This holds particular significance for nations with substantial potential in the tourism industry, where the hospitality sector acts as a linchpin for tourism recovery and presents compelling opportunities for impactful investments. As energy shortages and dependence took center stage in 2022, the research calls for the exploration of alternative renewable energy sources and the development of new commodity markets to invigorate energy sector growth. Against the backdrop of the hospitality industry’s post-pandemic resurgence, the integration of impact investing emerges as vital for both developing and developed nations. Given the prevailing global environmental crisis, the study underscores the imperative of effective international cooperation mechanisms to tackle environmental challenges, positioning impact investing as a catalyst for achieving sustainable economic development goals, advancing eco-friendly practices, and addressing global environmental imperatives.

We have recently reported that methylene blue (MethyB) was able to inhibit epinephrine-induced arrhythmias and cardiac muscle injury. In this study, we investigated the effect of nitric oxide synthase inhibition by NG-nitro-L-arginine methyl ester (L-NAME) on cardiac arrhythmias, and myocardial damage induced by epinephrine in rats. Whether nitric oxide inhibition would affect the antiarrhythmic and cardiac protective actions of MethyB was also examined. L-NAME (40 mg/kg), L-arginine (200 mg/kg) + L-NAME, or MethyB (100 mg/kg) + L-NAME were given intraperitoneally (i.p.). Cardiac arrhythmia was then induced with intravenous (i.v.) injection of 10 μg/kg epinephrine. Results showed that epinephrine injection caused marked bradycardia (221.0 ± 1.37 vs. 409.4 ± 3.18 beats/min), shortened QTc interval (0.096 ± 0.0093 vs. 0.177 ± 0.0008 s), increased QRS duration (0.040 ± 0.0035 vs. 0.0185 ± 0.0002 s), decreased R wave amplitude (0.176 ± 0.0051 vs. 0.21 ± 0.0009 mv), ST segment height (-0.026 ± 0.007 vs. -0.002 ± 0.0005 mv), and induced ventricular extrasystoles. L-NAME given to untreated control rats resulted in a decrease in heart rate (288.2 ± 0.88 vs. 409.4 ± 3.18 beats/min), and increased R wave amplitude (0.436 ± 0.004 vs. 0.21 ± 0.0009 mv) compared to controls. L-NAME did not cause extrasystoles in untreated control rats but significantly increased the number of extrasystoles and duration of arrhythmia in the epinephrine-treated group. The administration of L-arginine (200 mg/kg, i.p.) to epinephrine plus L-NAME-treated rats resulted in increased heart rate and markedly decreased the number of extrasystoles and duration of arrhythmia. Methylene blue given at 100 mg/kg to rats treated with epinephrine and L-NAME caused a marked increase in heart rate. It also normalized QRS duration, prevented ST segment depression, markedly suppressed ventricular extrasystoles, and decreased the duration of arrhythmia compared with either epinephrine or L-NAME plus epinephrine-treated groups. Epinephrine injection caused disorganization, and necrosis of cardiac cells, interstitial hemorrhage, and cellular infiltrations. These changes were markedly improved by treatment with either L-NAME or L-NAME/MethyB. These results suggest that (i) inhibiting nitric oxide synthase by L-NAME increases epinephrine-induced arrhythmia which is inhibited by L-arginine or MethyB; (ii) either L-NAME alone or in combination with MethyB prevented cardiac muscle injury induced by epinephrine; (iii) L-NAME did not prevent the cardiac protective and antiarrhythmic actions of MethyB.

The aim of this study was to estimate the relationship of the anthropometric parameters of an individual with the strength of the hand and the nature of the load distribution in its various zones when performing a cylindrical grip in practically healthy individuals. Anthropometric parameters and the results of biomechanical examination of both hands were analyzed in 78 practically healthy individuals (39 men, 39 women) of the most able-bodied age (from 19 to 50 years). The height and weight of the volunteers were measured using a manual electronic dynamometer ""Jamar Smart"" – the strength of the right and left hands (in kilograms). The dynamometry of the hand was performed in a sitting position, while the arms of the subject were located on the armrests, the elbow was bent at an angle of 90°, the forearm was in a neutral position, and the hand was in the extension position in the wrist joint at an angle of about 30°. The anthropometric characteristics of the hand were recorded by measuring (in cm) the lengths of the rays of the hand and fingers, and the length and width of the palm. Determination of the degree of load on various parts of the brush (as a percentage) was carried out using the hardware and software complex ""Teksan"" (USA). It is established that the strength of the brush depends on the anthropometric characteristics of the individual and its linear dimensions: the ""longer"" and ""wider"" the brush, the higher its strength indicators. When performing a cylindrical grip, the maximum load falls on the fingers, among which the I-IV are the most involved, to a lesser extent – the V finger and the tenar area. It was revealed that the load distribution indicators for different zones of the right and left hand differ: when performing a cylindrical grip with a weaker brush, the main load falls on the tenar area and the first finger. At the same time, the achievement of maximum grip with a weaker brush is achieved by the maximum involvement of small hand muscles in the process.
