Published: June 2022

Pendahuluan: Hubungan kadar magnesium (Mg) serum dengan luaran jangka pendek stroke iskemik (SI) masih belum banyak dipelajari sehingga menarik untuk diteliti. Metode: Dilakukan suatu penelitian kohort prospektif terhadap subjek dengan SI akut di RSUP Prof. Dr. R.D Kandou Manado, Indonesia antara bulan Oktober 2019 hingga April 2020. Subjek yang memenuhi kriteria penelitian diperiksa kadar Mg serum dan skor National Institute of Health Stroke Scale (NIHSS) secara berkala selama tiga minggu. Hubungan kadar Mg serum dan semua pengukuran NIHSS diperiksa dengan analisis bivariat lalu dengan regresi linear. Hasil: Didapatkan 65 subjek (33 laki-laki) dengan rerata usia 57,9 tahun. Median awitan SI adalah 24 jam sebelum masuk rumah sakit. Median tekanan darah sistolik adalah 150mmHg. Rerata kadar Mg serum subjek adalah 1,96mg/dl. Terdapat delapan subjek dengan kadar Mg serum di bawah normal. Kenaikan Mg serum meningkatkan skor NIHSS awal tetapi tidak bermakna secara statistik (p=0,06), namun berhubungan dengan besarnya perubahan skor NIHSS awal dan minggu III (p=0,04). Kesimpulan: Pasien stroke iskemik umumnya memiliki kadar Mg serum dalam batas normal. Semakin tinggi kadar Mg serum makin besar pula perubahan antara skor NIHSS awal dan minggu III sehingga nampaknya memperburuk luaran.

Dermatophytes are a group of fungi that cause an infection called dermatophytosis. They are mainly classified into three anamorphic genera: Trichphyton, Microsporum and Epidermophyton. Sixty-five samples were collected during the period from the middle of January to the end of September of the year 2019. The clinical specimens (hair, nail and skin) were collected from 58 patients who were clinically diagnosed with dermatophytosis. Molecular identification was done by using the fungus-specific universal primers (ITS1 and ITS4) for the amplification of the ITS region in the rRNA gene. For species identification, BstN1 restriction enzyme was used for the digestion of the amplified ITS products to produce distinct band patterns. The distribution of dermatophytosis among the patients was 52.3.%, 41.5%, 3.1%, 1.5% and 1.5% for Tinea nail, Tinea capitis, Tinea corporis, Tinea pedis and Tinea imbricate, respectively. Nighnteen clinical isolates of dermatophytes showed positive culture. Trichophyton was the most common genus with 15 sample (78.9%), followed by Microsporum with 4 samples (21.1%) and no Epidermophyton were found. The most common species was T. rubrum (n=5, 26.3%), followed by T. verrucosum (n=3, 15.8%), then T. mentagrophytes, M. Canis, M. audouinii and T. schoenleinii with tow isolates for each (10.5%). The amplification of ITS regions was successful in certain samples by using the fungus-specific universal primers (ITS1 and ITS4) and PCR-RFLP technique

Published: June 2022

The impact of the fuel injection of fuel atoms on engine performance has been investigated to improve fuel efficiency and waste disposal features. The fuel swirl method for injection atomization was evaluated both by the analysis of the fuel flow and the sample test. The goal of the paper is to establish good fuel atomization over the range of engine performance. As a result of our studies, it has been concluded that the desired atomization can be achieved when gasoline is thrown into a circular motion. Fuel spray and atomization features play an important role in the performance of internal combustion engines. An atomization study to evaluate the numerical fuel injection used in the IGC (Inner Guide-vane Combustor) under various combination and performance conditions has been performed to determine the suspension of the proposed fuel injection to be used in the IGC. Additional results have shown that a single-hole fuel injection, forward injection direction, and a splash of ‘
Experimental and Computational Investigation of Divergent Thrust Losses In Rocket Nozzles
Authors: Arya Vaibhav , Kapse Anushka Sunil
Published: June 2022

The nozzle is a critical component of any rocket engine because it transforms high pressure and high temperature (with sluggish net velocity) within the combustion chamber into high velocity but low pressure. Individually, the molecules in the mixed propellants have rapid velocity in the combustion chamber, but directions are randomly pointing in all directions. A convergent-divergent nozzle, also known as a CD nozzle, is fashioned like a tube with two bulging ends and a thin part in the center. This structure/design provides the nozzle with a balanced shape. By turning the flow's heat energy into kinetic energy, the nozzle accelerates hot, pressured gas traveling past it in the axial (push) direction. Whereas the nozzle provides the acquired incremental thrust to the rocket engine, it also results in unwanted thrust losses. Out of which divergent losses in the divergent section are the primary foci of our research. Moreover, in this research paper, we produced verified results to reduce the thrust losses at the divergent sections of the nozzle by optimizing the nozzle with different half divergent angles.
موجات الاحتجاجات في العراق بعد 2003: أسبابها وأثرها على العملية السياسية في البلد

لا يمكن فصل ما جرى في العام 2011 من مظاهرات وما بعده فالأسباب التي خرج لأجلها المتظاهرين، كان من اسبابها فشل الحكومات المتعاقبة بعد الاحتلال من توفير الأمن والخدمات، لانتشار الفساد المالي والاداري، وهي تهمة تكاد تكون سمة وصفه تسندها الأدلة والوثائق من ذات الاطراف المشاركة بالعملية السياسية، واذا كان هذا السبب أحد الاسباب التي أدت لانتفاضة 25 فبراير/ شباط 2011 وما تلاها وصولا لمظاهرات العام 2013، وأسبابه تمثل اهمية كبرى لطيف واسع من العراقيين، كتقييد الحريات وكثرة عمليات الاعتقالات والاخفاء القسري للمواطنين، لتكتمل هذه الصورة المشوشة مع صورة اخرى حصلت بعد العام 2014، فزادت المعاناة والتحديات، فزادت من اعداد المغيبين، فيما اصبح طيف واسع يسكنون اما في مخيمات لللاجئين او في مناطق تنعدم فيها الخدمات لا تصلح للسكن على وفق ابسط المعايير الانسانية.

وإذا كانت هذه الصورة تمثل جزء من العراق، فان الجزء الاخر منه لا يعيش بحال أفضل منه بفقدانهم للخدمات، ويعيش الشباب في حالة من الضياع نتيجة قلة فرص العمل وانتشار المخدرات، فبرزت مظاهرات مناطقية سنوية يوحدها الاسباب التي خرجوا لأجلها، فضلا عن مظاهرات متعددة من العاطلين عن العمل، وكذلك ساعدت تلك الاسباب في انتشار عصابات الجريمة المنظمة، نتيجة انفلات وانتشار السلاح، والذي يتسبب بالكثير من الصدامات بين العشائر العراقية، والنتيجة مظاهرات أكتوبر/ تشرين الأول 2019. ومع ما حققته تلك الاحتجاجات من نتائج بتغير الحكومة واجراء انتخابات مبكرة على وفق قانون جديد قسم المحافظات الى مناطق انتخابية بدل عن المحافظة منطقة انتخابية واحدة، مع هذا خرجت هنا وهناك العشرات وربما المئات من المظاهرات والاحتجاجات الفئوية.

هذه الاسباب وغيرها كانت وما تزال تشكل تحديات أمام أي حكومة، لاسيما حكومة مبنية على التوافق والاصطفاف الطائفي، وقد فشلت كالعادة على تشكيل حكومة جديدة رغم مرور ما يزيد عن تسعة أشهر من اجراء الانتخابات المبكرة في أكتوبر/ تشرين الأول 2021، وهو ما تنطلق منه فرضية البحث.
Green supplier selection with integrated multi-criteria decision making techniques
Authors: MERCAN Yasin , ÇETİN Onur
Published: June 2022

The concept of Green Supply Chain Management (GSCM), whose importance has increased in recent years, is considered as a supply chain that prioritizes environmental impacts in all its activities. Nowadays, businesses are considered not only in terms of their economic performance, but also in terms of their environmental performance which makes GSCM important. However, GSCM cannot be conducted without the participation of the suppliers. Due to this fact, correct determination of their suppliers has vital importance in developing a better GSCM performance. While there is a plenty of research in many sectors in GSCM literature, the research in the paint subfield of the chemical sector, which has a great environmental impact, is limited. It is seen that Multi-Criteria Decision Making (MCDM) techniques are frequently used in supplier selection studies, however, there are few studies where the results of different approaches are compared and integrated. In this research, green supplier selection is conducted using different MCDM technics, and the results are compared and combined. In the study, green supplier selection was carried out in the paint sub-branch of the chemical industry with the MOORA-Ratio Method, MOORA-Reference Point Approach, GRA and COPRAS methods, each of which is integrated with the ANP Then, the COPELAND method was used to obtain a general ranking. This research contributes to the literature by proposing a unique model in terms of the applied sector and integrating MCDM method results. The model proposed in this study can help the decision makers in order to build a green supplier selection model.

Authors: Bakirova Samal , Kussanova Anipa
Published: June 2022

Objective requirements for the production process, the interaction of classical ballet and national traditions require new approaches for creating dance projects in the small forms genre. The goal is to explore the most significant creative projects of domestic choreographers in the context of the relationship between traditions and innovation in order to determine the most correct solutions to issues of national and supranational choreography in domestic directing. The objectives are to consider the peculiarities of the small choreographic forms development in the national style, to identify the main trends in their development in the productions of Kazakh choreographers and on this basis to reveal the relationship and interaction between national content and supranational stage embodiment. The methodological basis for the study of issues related to the creation of dance works in the small forms genre is a systematic approach to the issue of the modern Kazakh choreography stylistics peculiarities. The main methods, used during the study, were the synthesis methods of choreographic art, the national dance interpretation and the principles of directorial techniques in creating small forms.
At the current stage of the national choreography development, the most landmark and significant productions are the innovative ones of Mukaram Avakhri (Astana Ballet Theater), Gulzhan Tutkibayeva (Abay Kazakh National Theatre Opera and Ballet). Analysis of their interpretation of traditional forms of dance led to the conclusion that Kazakhstan created its own national directing style in the creation of choreographic works of small forms. During the discussion block, the main result of the comparative analysis of creative projects for leading domestic choreographers was the identification of the most significant methods and techniques of their work on the creation of highly artistic projects in the field of choreography as a multi-level, multi-component and developing art.
In the context of increasing competition among Kazakh theaters and creative groups working in the style of national choreography, the introduction of modern methods and principles into the directing process is becoming particularly significant. A thorough study of all components of this process will contribute to the further successful development of the entire domestic choreographer's art.
Искусство в поисках стратегии национального самоопределения (на примере турецкой архитектуры)
Authors: Кононенко Евгений
Published: June 2022

Сознательные апелляции к приоритету «национального» могут иметь различноеидеологическое наполнение, от которого зависит выбор стратегии самоопределения конкретной культуры в определенный отрезок времени. Каждую из рассматриваемых в исследовании стратегий можно обозначить как «национальную», и каждая из них, с одной стороны, отвечала современным ей интернациональным трендам, а с другой – была во многом инспирирована реакцией на «вестернизацию» и «космополитизм» и осознанной необходимостью противопоставить угрозе экспансии интернациональной культуры (трактуемой как «чужеродная» и «безликая») самобытность, традиционность, почвенничество.Показательным примером для демонстрации изменения представления о «национальныхценностях» и смены подобных стратегий оказывается зодчество поздней Османской империии Турецкой республики. В XIX–XX вв. османская/турецкая архитектура неоднократно программноакцентировала приоритет национальных традиций по отношению к заимствованныминтернациональным стилям, однако критерии культурной самоидентификации в рамках«национальной идеи» оказывались различными. Выделены три подобных стратегии: «имперская», которой соответствовал неоосманский стиль конца XIX в.; «националистическая», выражавшая тюркистские идеалы младотурок; «регионалистская», отвечавшая расширенному пониманию национального наследия в Турецкой республике. В рамках этих последовательных стратегий менялись риторические цели официальной культуры, по-разному выражалась национальная идея, формулировались задачи искусства, осуществлялся выбор художественных образцов. Понятие «национальное» может быть использовано для идентификациии самоидентификации той или иной культуры в интересах официальных доктрин или вопреки им, в пределах широкой или узкой этнической категории, государственных границ и/или региона, не совпадающего с административно-политическим делением.
Between conservatism and modernism in dacwahon radio: A study of Madrasatud Dalīlish Shariciy and Manhajuahlus Sunnah programmes in Ilorin, Nigeria
Authors: Shittu Abdulwahab Danladi , Olalekan Ibrahim Mubarak
Published: June 2022

The exploration of electronic media, among other things, as a veritable tool through which the pristine messages of Islam are conveyed has not gone unrecognisedby contemporary scholars in Nigeria. However, the manner and style adopted by advocates on propagating slam differ and with this difference, the result of the act also differs This work comparatively studied two radio dacwah programmes in Ilorin; Madrasatud-dalīlish-shariciy and Manhajahlus Sunnahwaljamaca, with a view to identifying the impact of each of the two programmes on the masses. Giving the structural survey of selected episodes, the study is descriptive, and comparative in focus; therefore, the researchers adopted a combination of descriptive the comparative research methods. Findings of the work revealed that Manhajahlus Sunnahwaljamaca is largely satirical while Manhajdalilish-Sharica is academic. It is,however, recommended that the focus and locus of any dacwah activity should principally be both mild and academic. This, as a matter of fact, could be actualized by creating an institution that regulates dacwah conducts in every society.
nexus between tithing and prosperity in United Missionary Church of Africa, Nigeria
Authors: Fawenu Bamidele Olusegun
Published: June 2022

Tithing, which refers to the practice of giving one-tenth of one‟s income or produce for religious purposes, is a prominent Judaeo-Christian pactice. Extant studies have focused more on the controversy surrounding the applicability of the Old Testament tithing law to Christians than its connection to the lived experience of tithers. Therefore, this study juxtaposes the practice of tithing with lived experiences of tithers in United Missionary Church of Africa (UMCA), Northcentral Nigeria with a view to ascertaining the extent to which compliance to the tithing injunction elicits God‟s blessing. This enquiry becomes germane due to the emphasis of pro-tithing churches on the inevitable nexus between prosperity and tithing. In-depth interviews were conducted on 32 purposively selected pastors and deacons: eight from each of the four language-groups districts — English-speaking district (ESD), Nupe-speaking district (NSD), Yoruba-speaking district (YSD) and Hausa-speaking district (HSD) — of UMCA. Copies of a questionnaire were administered on 757 randomly selected church members across the four language-group districts. Qualitative data were subjected to content analysis, while quantitative data were subjected to percentages. UMCA mmbers think of blessing attached to tithing largely as economic emancipation, health and security. However, the survey shows that occasional tithers experienced sickness: ESD (44.4%), NSD (54.3%), YSD (32.2%) and HSD (42.0%); financial difficulty: ESD (45.1%), NSD (78.3%), YSD (49.3%) and HSD (58.6%); and robbery: ESD (23.8%), NSD (16.0%), YSD (16.4%) and HSD (14.0%). Also, regular tithers avowed experiencing sickness: ESD (42.4%), NSD (77.9%), YSD (41.7%) and HSD (53.2%); financial difficulty: ESD (53.8%), NSD (95.4%), YSD (66.3%) and HSD (61.6%); and robbery: ESD (32.0%), NSD (27.7%), YSD (30.2%) and HSD (18.9%). Conversely, a good percentage of non-tithers claimed that they do not have such experiences in connection to defaulting in tithing; ESD (55.6%), NSD (66.7%), YSD (70.0%) and HSD (78.6%). The paper argues that a balanced teaching on material prosperity that does not give false hope and expectations to people should be re-emphasised among Christians generally and in UMCA specifically.
Knowledge, Belief and Justification of the African Conception of Reincarnation
Authors: Ajayi Toluwalase
Published: June 2022

The study examines the epistemic justification of reincarnation in African Philosophy. It is also an attempt to investigate the problem of reincarnation and the belief in the ancestral world. It deploys the critical tool of epistemic justification to determine the conditions that render the African conception of reincarnation defensible. Epistemic justification is a philosophical theory aimed at investigating the extent to which a person’s beliefs are knowledge-based and therefore worth holding. The paper defends the thesis that African idea of reincarnation is justifiable and that belief in reincarnation can coexist with the belief in the ancestral world without contradiction. Humans are reborn and come back into this world several times until they have sufficiently paid for all their past misdeeds and purified themselves, before their souls are released to go to the ancestral world. A person’s destiny is never fulfilled in the first trip; hence a rebirth or reincarnation takes place to give the individual a succeeding chance or chances to fulfill his or her original destiny.
Non-Contact 3D Characterization System of Scratch-Induced Surface Damage on Monolithic Glass Panel
Authors: Pan Zhufeng , Yang Jian , Wang Xing-er , Wang Yige , Li Gang , Jiang Xianfang
Published: June 2022

Glass material has been widely used in modern architecture. Scratch-induced surface damage of aged monolithic glass panel leads to the strength degradation of material and thus threatens the glass safety. Therefore, in order to accurately evaluate the strength of aged glass elements, it is crucial to extract key damage features including the damage location and depth in a precise way. This study aims to develop a non-contact stage-wise scanning method to extract 3D damage characteristics on glass surface, which can further facilitate the investigation into the associated influences on the flexural strength of glass. Coaxial double ring tests on annealed glass specimens under various magnitudes of applied loads were performed, which aimed to explore the influence of the surface damage on the flexural strength. Monocular microscope equipped with an industrial camera was used to detect damage area throughout the glass panel in the first stage rapidly. It was then followed by a chromatic confocal scanner to precisely measure the damage depth within local damage area. The results via confocal microscope scanning were considered as the reference values. It shows that the proposed method can be a potentially alternative solution instead of confocal microscope for damage quantification.
Potentials and Limits of Simplified Models for Linearly Restrained Glass Balustrades under Static Loads and Impact
Authors: Rizzi Emanuele , Bedon Chiara , Bez Alessia , Amadio Claudio
Published: June 2022

Glass balustrades are designed to prevent large deflections and high stress peaks under conventional lateral loads. In practice, linear restraints are generally described in the form of ideal linear clamps for glass, to replace the actual geometrical and mechanical properties of restraint components. This means that strong simplifications are introduced in place of multiple details and components expected to offer local flexibility and prevent premature stress peaks in glass. In this paper, attention is given to linear restraints that are commonly described in terms of “clamp” boundaries for glass panels under lateral loads. The use of simplified mechanical models to characterize the actual stiffness and linear restraints and components is addressed, with the support of refined Finite Element numerical models and literature experimental data for balustrades under twin-tyre impact.
Pilot Experiments for Multi-Criteria Human Comfort-Driven Structural Glass Design Assessment
Authors: Bedon Chiara
Published: June 2022

Civil engineering design and industry are continuously evolving with the support of advancements in technology. Digital tools are able to assist designers in solving several issues with more accuracy and minimized efforts. In parallel, maximization of human comfort is a target for various design procedures, where mathematical models and standardized protocols are conventionally used to optimize well-being of customers. Major challenges and troubles can indeed derive, structurally speaking, from human reactions, which are related to a multitude of aspects, and may further enforced by slender / transparent glass components. The so-called “emotional architecture” and its nervous feelings are intrinsic part of the issue, and hence the mutual interaction of objective and subjective parameters can make complex the building design optimization. This paper presents some recent studies in which human comfort for glass structures occupants is quantitatively measured, both with the support of remote digital technologies based on facial micro-expression analysis and in-field experiments able to capture kinematic and biometric parameters for customers moving in glass environments.
Thermal Rheological Behavior of Composite Interlayer in Laminated Glass
Authors: Xie Dongdong , Yang Jian , Wang Xinger , Zhao Chenjun , Jiang Xianfang , Li Gang
Published: June 2022

Laminated glass is growing its application in structural entities. The thermoplastic polymeric interlayer plays an important role in transferring force and achieving the composite action in laminated glass, which reveals evident temperature-dependent behavior. In this study, a novel composite interlayer (SGE®) was devised to improve the resistance of laminated glass against environmental actions and to enhance the post-fracture performance. It is comprised of modified ethylene-vinyl-acetate (PVE®) and polycarbonate (PC). Through dynamic mechanical thermal analysis, the temperature-dependent characteristics of SGE, PVE, and PC materials were investigated in detail. The results show that the thermal rheological behavior of SGE is similar to that of PVE. The temperature ranges of glass transition and crystal melting of SGE material are -35°C ~ -25°C and 45°C ~ 75°C, respectively. The corresponding ranges are -35°C ~ -15°C and 35°C ~ 65°C for PVE material. And temperature ranges of the main transition are influenced by imposed frequency. Besides, the relationship between time and temperature for PVE, PC, and SGE material is extensively complicated and the complexity depends on the investigated mechanical property, temperature range, and time range. And the simple thermal rheological behavior emerges in the storage modulus of polymers, but loss modulus and loss factor conform to the complex thermal rheological behavior at the temperature range of -50°C ~ 120°C under the frequency range of 0.1 Hz ~ 10 Hz.
Color Depth
Authors: Newell Catie , Craney Ryan
Published: June 2022

Color Depth is a material-based research project investigating the optical and structural properties of thick glass. The research is driven by an interest in optical gradients of transparency and color, which are designed through a manipulation of geometric form and composition. These qualities can be attributed to the interrelated optical effects created through reflection, refraction, and volume color, in direct correlation to the geometry of individual glass pieces and overall glass assemblies. An example of this can be seen in viewing a monolithic volume of glass that would appear to change color by varying the depths of its form. This concept was originally discussed in Josef Albers’ Interaction of Colour, and applied more specifically to glass in recent essays by Heike Brachlow.  Color Depth utilizes this phenomenon of perceived color variation to construct and analyze architectural glass forms in both physical prototypes and design speculation. To evaluate architectural design opportunities, a multi-objective optimization workflow simulates and evaluates varying glass colors, forms, and compositions to achieve a desired visual effect. Additionally, the digital optimization process reveals patterns and visual effects that further the understanding of optical gradients when applied in an architectural context with various seasonal and diurnal environments. Keying into the geometry of glass– to deploy changes in color, darkness, or translucency—Color Depth ties together the physical attributes of a material system with its surrounding light.
Influence of Elevated Temperature on the Mechanical Properties of Transparent Adhesive Glass-Glass Joints
Authors: Zikmundová Markéta , Eliášová Martina
Published: June 2022

Glass is an attractive, transparent but brittle material which is increasingly popular in civil engineering. Not only small and secondary glass structures such as canopies or railings, but also load-bearing structures or structural elements such as stairways, beams, facades, etc. are commonly designed today. The wider use of glass places demands on the connections of glass-to-glass or glass-to-other materials. Mechanical connections are commonly used owing to their known mechanical properties but there is pressure to use adhesives for their considerable advantages. Unfortunately, there is not enough information about the mechanical properties of adhesives exposed to environmental effects and elevated temperature. The paper is focused on experimental testing of glass-to-glass connection using transparent adhesives. The specimens were prepared as double-lap shear joints with 1 mm adhesive joint thickness. In the study, three two-component epoxy adhesives were selected, one rigid adhesive and two semi-rigid adhesives. Specimens were tested at room temperature (reference set) and at elevated temperature (80 °C), six sets of specimens were prepared in total. The test was controlled by displacement with continuous loading until the specimen’s collapse. The cross-head speed was 0.05 mm/min. Shear strength at failure rapidly decreased for specimens exposed to elevated temperature and each specimen failed due to loss of adhesion between adhesive and glass.
High-Temperature Behavior of Silicone Sealants
Authors: Hayez Valérie , Scheutz Georg
Published: June 2022

Since the early 2000s, an increasing number of globally reported fires in tall buildings, which have spread quickly, have been attributed to the façade. These dramatic events have raised concerns regarding the fire risk posed by materials used in façades and inside the building. Improved performance in both reaction to fire and fire resistance is a necessary requirement  for construction materials. Silicone is used in many locations of the façade and buildings, such as sealing of linear joints or firestopping of penetrants in fire-rated walls and floors. Standardized testing enables the evaluation of the fire resistance of such linear and penetration seals in terms of integrity (avoiding the passage of hot smoke and flames) and insulation (limiting the rise of temperature on the non-exposed side). Silicone can also be used to assemble glass-to-metal frames in bonding applications such as smoke barriers. In these applications, retention of bonding and the mechanical properties of the silicone are a cause for concern when exposed to smoke and high temperature. This paper reviews the high-temperature behavior of a selected range of silicones used for sealing and bonding in construction.

Glass surfaces are characteristic elements of façades and make a significant contribution to the authenticity of architectural monuments. Glass as a material is considered an important testimony of its time. Depending on the manufacturing process, it differs both in surface and material composition. The period of high modernism (ca. 1880-1970) overlapped with the technical developments of the industrial revolution, which led from manual production to industrial production. The further development of manufacturing processes as well as the dimensions and qualities of the glass thus shaped the development of glass constructions, which had to be made increasingly slimmer over time in order to guarantee a high degree of transparency. Today, historical windows are often replaced by new glazing made of float glass, which can cause the authentic character of buildings to be lost. A team working on the research project at the Technical University of Dresden and the University of Bamberg has therefore set itself the goal of examining in detail the glass and its construction in the period from around 1880 to around 1970. The aim is to define the living character of industrially manufactured glass from the time before the introduction of float glass as an authentic and style-defining feature of the period. The present work focuses on the chronological presentation of the development of glass designs. Furthermore, the development and use of refined flat glass is analysed and presented. This includes wired glass, laminated glass, thermally toughened glass, insulating glass and curved glass. The significance of historical glass constructions for engineers and planners can be derived from the results and the evaluation.

When glass is laminated for safety reasons, it usually blocks UV radiation partially or even completely when UV blocking materials are used. In the last decade, there has been an increasing interest in interlayers with high UV transmission, especially in relation to greenhouse applications. In this paper, we present an overview of the effects of UV transmittance on plant growth and development, in order to advice on the use of the high transmission interlayers versus the standard interlayers. Using UV transmitting films instead of UV blocking films has opportunities to alter plant growth and morphology. In general, plants grow more compact with increased UV transmittance, growth and biomass are reduced, flowering is stimulated (although the effects are species dependent), concentrations of secondary metabolites which are positive from nutritional perspective are stimulated and flower appearance (color) can be positively influenced. Pollination by bees is improved when UV is present and plant resilience to pests and diseases is improved. These results show that UV transmitting materials can have potential to be used in for example botanical gardens, office centers and garden markets, where producing biomass might even be unfavorable. On the contrary, the increased ornamental value by improved shape and flower color will be appreciated. Therefore, these aspects of transmitting UV to plants can have potential for markets where plant production is not the main goal.

This contribution addresses the impact of tempering processes on the emissivity of LowE glass. The current status of a measurement series conducted at various tempering sites on different types of LowE glass is presented. Emissivity measurements using inductive eddy current sensors have been made on glass before and after tempering. The obtained data shows an improvement by factor 2 in emissivity depending on coating type. Effects from tempering recipes and the resulting emissivity homogeneity have been analyzed. Measurements also show significant worsening of the emissivity by the use of wrong tempering settings where too little convection occurs during heating that cause glass bending leading to the well-known white marks in the center of the glass along with significant loss in emissivity. Assessment of the glass emissivity properties as well as the negative effects of poor furnace recipe optimization on coatings were measured by eddy current systems, which rely on inductive methods for contact or non-contact real-time emissivity assessment. Comparison to thermographic images are shown and discussed. Finally, the status of measurement and analysis are summarized and the potentials to use of these phenomena are discussed.
Extreme Cold-Bending: Geometric Considerations and Shape Prediction with Machine Learning
Authors: Rahimzadeh Keyan , Levelle Evan , Douglas John
Published: June 2022

Cold-bent glass is seeing increasing adoption in construction projects with non-planar geometries. This paper presents work undergone for a set of four high-rise towers, featuring 11,136 unique cold-bent panels, hundreds of which are pushed beyond 250mm. The panels are all unique, non-rectangular, and in some cases, slightly curved. The challenging geometry complicates the prediction of the final panel shape, which is an essential step for producing fabrication drawings of a panel’s flat shape prior to bending. While Machine Learning is still a nascent technology in the AEC industry, prediction is a class of problems for which many Machine Learning techniques are ideal, especially when dealing with a large quantity of data, or in this case, panels. The paper discusses the geometric characteristics of highly bent glass, a methodology for the shape prediction of the panels, and the use of Machine Learning in its implementation. The methodology was deployed for over 3,500 pieces of installed architectural glass, and was shown to reduce geometric deviations as much as 75%, down to sub-millimetre tolerances.

“Diabetes mellitus”, is one of the most common non-communicable diseases worldwide. India faces several challenges in diabetes management, including a rising prevalence in urban and rural areas, lack of disease awareness among the public, limited health care facilities, high cost of treatment, suboptimal glycaemic control and rising prevalence of diabetic complications. Insulin therapy for diabetes is most commonly delivered via subcutaneous injections, up to four times a day. Long-term insulin therapy, compounded by the invasive nature of its administration, has caused problems with patient compliance, ultimately influencing patient outcomes. There is an increase in the prevalence of type 1diabetes also, but main cause of diabetic epidemic is type2 diabetes mellitus, which accounts for more than 90 percent of all diabetes cases. Type2 diabetes is a serious and common chronic disease resulting from a complex inheritance- environment interaction along with other risk factors such as obesity and sedentary lifestyle.

Regulatory affair is comparatively new profession which developed from the purpose of governments to protect public health by governing the quality, safety and efficacy of product within regulated industries. Regulatory affairs in the pharmaceutical industry play an important role as the pharmaceutical sector is rising very rapidly and there is want of regulatory affairs professionals to provide the current needs of industries for the global competition. Regulatory affairs professionals serve a critical function throughout a medical device’s product lifecycle-leading pre market strategy, drafting regulatory submissions, and ensuring post market compliance. The medical device industry plays a key role in the health care ecosystem by providing innovative solutions that improve patient outcomes. Every company seeks to innovate, whether through iterative updates to existing technology or by developing new devices that could offer a more effective treatment to a particular disease or condition. Many countries throughout the world have their own medical device regulations, however, and regulatory affairs is required to understand the difference in global regulatory requirements to ensure that new products can be marketed. The global regulatory landscape is always changing, so successful regulatory affairs teams follow global trains and are aware of new regulations or programs.

Using deep learning and computer vision, image caption generation identifies the context of an image and comments on it with the most relevant captions. It entails an image's epithet combined with English keywords, as well as datasets provided during model training. We produce a vectorized representation of an image using a deep Convolutional neural network, which is then fed into a long-short-term memory (LSTM) network, which provides captions. LSTM (Long short-term memory) is also one of the RNN (Recurrent Neural Network) constructs, mainly utilized in the deep learning discipline. The vivid applications of image captioning are natural language processing applications, recommendations in editing applications, helpful for virtual assistants, for indexing the image, for the blind or partially-sighted people, for the internet community, etc.
