An Overview of the Perception of Sayyid Abū ’l-A‘lā Mawdūdī in Turkey
Authors: Ahmetoğlu Gülşen Yağır
Published: February 2023

Sayyid Abū ’l-A‘lā Mawdūdī (d. 1979) is one of the leading Islamic thinkers of the Indo-Pakistan subcontinent. He gained an influential place in the twentieth century because of his religious and political thought. His revisionist interpretations of various theological and epistemological aspects of Islamic thought brought about a revolution among Muslims across the world. This article reviews the reception of Mawdūdī’s thought in Turkey and its social and political impact. It begins with exploring the fundamentals of Islamism in Turkey and the theological and political variables that influence it. Then the article discusses the process that started with the translation of Mawdūdī’s works into Turkish, his recognition in Turkey, and the impact of his thought on the Turkish youth. It also provides a panoramic view of the process in which these translation activities were carried out from the 1960s to the 1990s. It also assesses the arguments of those who consider his thought a deviation from the traditional understanding of religion. The article concludes that Mawdūdī significantly influenced the idea of Islamism, especially among the youth, and that his religious and political views still maintain their importance. On the other hand, some groups, particularly those with traditionalist and conservative views, see Mawdūdī’s perspective of religion and politics to be different from Islamic tradition.
Some recent advances in electromagnetic, acoustic, and flexural wave scattering: CPAL and shape recognition
Authors: Farhat Mohamed
Published: February 2023

In the first part of this webinar, I will present our recent contributions in the coherent perfect-absorber and laser (CPAL) for electromagnetic, elastodynamic, and acoustic waves. This intriguing effect is enabled by parity-time (PT)-symmetry breaking condition and leads to extremely precise rf sensors. In addition, the lasing operation of CPAL device is first observed theoretically and validated numerically (3D COMSOL full elasticity simulations) in elastic thin-plates. We further propose to accomplish ultra-sensitivity and robustness to noise by demonstrating a CPAL-locked sensor to detect extremely small-scale pressure perturbations. The results show that the sensitivity and resolvability of the CPAL-locked sensor may go well beyond the traditional acoustic sensors.

In the second part, we propose a new approach for acoustic airborne waveguiding that relies on imposing spinning on a column of air, leading to high modified acoustic refractive indices for specific azimuthal modes, reminiscent of acoustic spinning fiber (ASF). The obtained effect is nonreciprocal and tunable via the spinning frequency. It may be seen as the counterpart of the “Zeeman effect”. The concept is shown in the realm of airborne acoustics, yet it can be extended to other wave types, e.g., optics or elastodynamics.

Last but not least, I will shortly discuss a generative deep learning approach for shape recognition of an arbitrary object from its acoustic scattering amplitudes. The model exploits adversarial learning and variational inference to predict the unique shape of the object. The nonunique solution space is overcome by the multiangle and multifrequency phaseless far-field patterns.
Representation of Gender Violence in Jaishree Misra’s Afterwards
Authors: Ritika Kumari
Published: February 2023

Gender violence is one of the major social issues which needs proper attention. It is one of the worst crimes of human society. ‘Gender Violence’ is an umbrella term that includes a large number of crimes directly or indirectly posed against a person’s sexuality. Several crimes like domestic violence, marital rape, human trafficking, honor killing, and other such abuses are heinous realities of the contemporary Indian society. To a large extent, the trauma of gender violence is not only physical but also psychological. Sadly, it has remained neglected for a very long period. However, by the twentieth century, voices fighting against such issues have gained wide recognition. The literary representation of sexual violence in Indian English literature is a way of giving voice to silent unheard victims and is worth critical attention. Jaishree Misra is a contemporary Indian English novelist delineating various socio-cultural issues of the contemporary Indian society through her large gamut of literary works. Her novel Afterwards (2004) deals with the life of a woman named Maya, trapped in a loveless and suffocating marriage. This research paper attempts to study the textual representation of sexual violence in the contemporary Indian English fictions with special attention to the selected literary work.
Oxidation response of ZrB2–SiC–ZrC composites prepared by spark plasma sintering
Authors: Ghasilzadeh Jarvand Mohsen , Balak Zohre
Published: February 2023

Considering the importance and application of ultrahigh temperature ceramics in oxidizing environments, in this research, the effect of ZrC content and spark plasma sintering parameters (temperature, time and pressure) on the oxidation response of ZrB2–SiC composites has been investigated. After fabricating the ternary composite samples in different SPS conditions and with different amounts of ZrC, the post-sintering oxidation process was carried out in a box furnace at the temperature of 1400 °C. Increasing the time and temperature of the SPS process caused the decrease in the oxidation resistance of the samples. The reason for such observations was attributed to the extreme growth of grains with increasing the temperature and time of the sintering process despite the better densification of the samples. This research did not reach a clear result about the effect of SPS pressure on composites oxidation behavior. Increasing the amount of ZrC also did not have a positive effect on the oxidation resistance of the samples because this phase itself undergoes oxidation at low temperatures.
Le tante crisi e le PMI italiane. Dinamiche, trasformazioni e politiche pubbliche
Authors: Brancati Raffaele
Published: February 2023

Over the past decade, the Italian industrial system gained appreciable progress featuring an increasing spread of innovative activities. Using updated microeconomic data, we highlight a number of critical factors affecting this process. The possibility of implementing effective policies and overcoming imbalances is conditioned by external constraints, typically concerning the ‘two capitals’: financial and human capital. For the financial structure and liquidity constraints, economic policy interventions have produced appreciable results. Concerning the strengthening of human capital, on the other hand, measures were mostly ineffective in contrasting a constraint that has become increasingly significant over time. Active policies are required, but directly addressing the specific needs and difficulties of operators.
Productivity and wage effects of the Iso9001 certification for leader and laggard companies in Italy
Authors: Pompei Fabrizio
Published: February 2023

In this paper I study whether the adoption of the Iso9001 certification in Italy, between 2011 and 2019, has helped small firms to reduce the gap in productivity, profitability and wages paid to the workers, with the leading group of firms operating on the frontier. After a pooled OLS estimation, a difference-in-difference model with fixed effects has been applied. I find that Iso9001 certification does support firms below the frontier to partially recover the gap in terms of multifactor productivity incorporating the mark-up and profits, while no robust effect has been detected for the mark-up corrected productivity and wages.
Determinants and wage effects of overeducation in Italy
Authors: Mandrone Emiliano , Pastore Francesco , Quintano Claudio , Radicchia Debora , Rocca Antonella
Published: February 2023

This paper aims to study dimentions of educational mismatch and quantify its effects on wages. Using the Inapp-PLUS survey, we measure both overeducation/skilling and undereducation/skilling in Italy, providing five different measures of the educational mismatch: three of subjective type and two of objective type. They are also synthesized in a single indicator, able to give a measure of the degree of severity of overeducation. These measures are provided both for university graduates and for upper secondary school graduates. Results highlight that the condition of overeducation is typical of males, younger workers, people coming from lower-income families, informal channels of recruitment and with a humanistic educational background
Holograms, (Dis-) Embodied Intimacy, and Posthumanism in an Age of Ubiquitous Computing
Authors: Lindop Samantha Jane
Published: February 2023

As computational technology becomes unobtrusive and ubiquitous, interconnections between humans and software are increasingly seamless, challenging clear demarcations between organic and synthetic, material and immaterial. Central to these innovations are theories of posthumanism and scrutiny of the self in relation to technology. Posthumanism signifies a continuum of human existence that involves shaping and being shaped by the environment and innovations. This article examines the use of high-fidelity holographic technologies to facilitate human–software interrelationships. Drawing on fictional representation of human–hologram intimacy in Blade Runner 2049 and real-life creations Azuma Hikari and Hatsune Miku (who sometimes appears in holographic form), it argues that hybridized spaces created by ubiquitous computing coupled with holography promote and naturalize intimate posthuman fantasies. Partial disembodiment of humans in technologically mediated spheres, coupled with partial embodiment of software using holographic interfaces, generates liminal counter sites existing between the real and imaginary-other spaces that align with Michel Foucault’s concept of heterotopias; holograms, as visceral interfaces, produce simultaneously mythic and tangible contestations of the space in which we live. High-fidelity holography has the potential to radically transform human–machine interconnections now and in the future.
Lowell Martin: The Shaping of a Public Library Leader
Authors: Varlejs Jana
Published: February 2023

When Dr. Lowell Martin (1912–2003) was interviewed by the author and Dr. Caroline Coughlin in 1997, our initial questions arose from our connections with the Rutgers Graduate School of Library Service, of which he was the founding dean (1953–1959). Taking a fresh look at the interview record now reveals the importance of Martin’s early experiences working in the Chicago Public Library and studying at the University of Chicago’s Graduate Library School. This article examines the influence that Chicago institutions and individuals had on his long career as educator, writer, consultant, and leader. In the interview, Martin gave credit to specific influencers, but the overall nature and impact of his Chicago years are clearly visible in his work across decades.

Authors: Chen Carolyn L. , Lapsley Janis , Yaxley Page , Brown Megan , Wavreille Vincent A. , Tremolada Giovanni , Selmic Laura E.
Published: February 2023

Septic peritonitis is a life-threatening disease that can be caused by neoplasia, among other disease processes. There is no veterinary literature directly evaluating the outcome of patients with septic peritonitis caused by neoplasia. The objective of this study was to evaluate for differences in survival to discharge and complication rates between septic peritonitis caused by neoplastic and nonneoplastic disease in canine patients. A single-institution retrospective cross-sectional cohort study was performed, identifying dogs that were treated surgically for septic peritonitis between January 1, 2010, and November 1, 2020. A total of 86 patients were included, 12 with a neoplastic cause for septic peritonitis and 74 with another cause. The most common neoplastic lesions associated with septic peritonitis were gastrointestinal lymphoma and hepatocellular adenoma. Presence of neoplasia was not a significant factor for development of intraoperative or immediate postoperative complications, nor did it decrease chances of survival to discharge (P < .09). The diagnosis of a primary, localized, neoplastic lesion alone should not deter clinicians and owners from pursuing treatment for septic peritonitis.
Successful Resuscitation of Neonatal Kittens Delivered by a Perimortem Cesarean Section Following Maternal Cardiopulmonary Arrest
Authors: Racette Molly
Published: February 2023

A 9 yr old, unknown weight, intact female domestic shorthair presented for evaluation of dystocia with dyspnea. En route to the hospital for treatment, the owners noted the queen stopped breathing. On presentation, cardiopulmonary arrest was confirmed. The exact cause was unknown but suspected to be secondary to acute fulminant congestive heart failure or acute respiratory distress syndrome due to a large volume of serosanguineous fluid within the mouth and nose. Cardiopulmonary resuscitation (CPR) was immediately started. After 2 min of CPR without return of spontaneous circulation, the owners consented to perimortem Cesarean section. Two kittens were removed via emergency hysterotomy within 3–4 min. Both kittens were successfully resuscitated. CPR efforts were continued on the queen for 2 min after delivery of the kittens, at which time the owners elected to stop further resuscitative efforts. Both kittens were discharged from the hospital and were alive at last follow-up, 2 yr and 4 mo after birth. There are no previous reports regarding the use of a perimortem Cesarean section to deliver neonates in small animal medicine. Therefore, this report represents a novel treatment approach that can be considered in the case of maternal arrest during dystocia.
Kajian Filsafat Ontologi Martin Heidegger atas Peran Musik dan Nyanyian Liturgi bagi Perkembangan Hidup Umat Beriman
Authors: Dwiputra Malla Crysan , Pius Manik Robert
Published: February 2023

This article deals with the ontological philosophy of Martin Heidegger in the context of discovering the meaning of liturgical symbols, specifically one of liturgical music and chant in the Catholic Church. The aim of this study is to explain the symbolic meaning of liturgical music and chant and to reflect on its relevance in enriching the liturgical capacity of the faithful. The paper is intended as a literature review. The author reviews Louis-Marie Chauvet's book, Symbol and Sacrament, as well as other works about Heidegger's philosophy, such as the writings of Armada Riyanto. This study finds that liturgical symbols, such as music and chants performed in the liturgy, are not merely entertainment to please the eyes and ears of the people. These are symbols that transmit the content and the message of faith. The performance of liturgical symbols can help people understand and experience the strength and beauty of liturgical celebrations.
Ketidaksetujuan terhadap Interpretasi Pendamaian Stoa dan Kekristenan dalam Pemikiran Justus Lipsius
Authors: Theo Yohanes
Published: February 2023

Justus Lipsius drew up an intellectual project to reconcile stoic thought with Christianity. In this project, Lipsius started with two assumptions. First, Stoicism's “divine fire” as the highest principle is to be explained by making reference to Scripture where God manifests himself through fire. Second, destiny is a manifestation and an expression of Divine Providence that plays an important part in concrete situations. Has Justus Lipsius been successful at reconciling the Stoics and Christianity? This paper is intended to address this question using a literature review approach. The author goes through the philosophical thoughts of neo-stoicism, Justus Lipsius. Basically, Stoicism showed differences to Christianity. Stoicians believe that the Divine is material. Destiny and divine providence become one. Both are a series of causes that bring matters to mechanical work. Consequently, the space for freedom is almost nonexistent because stoic humans wish to align themselves with Nature fully. Christianity tells the opposite. God is nonmaterial, and the nuances of human freedom are held in high regard. As a result, Lipsius could not reconcile the Stoics with Christianity.

SIMULATION STUDY OF FINNED DOUBLE PIPE HEAT EXCHANGER
Authors: Anbu Clemensis Johnson  , Sadoon Mohammed Aws
Published: February 2023

Double pipe heat exchangers are extensively used in process industries. Increasing the surface area of heat exchanger results in enhanced heat transfer. In the current study double pipe heat exchanger was simulated using ANSYS Fluent simulator program. The fins were added to the outer surface of the inner pipe and the geometries studied were, rectangular, triangular and leaf shaped. Water outlet temperature of the heat exchanger was studied with mass flow rates of 0.20 kg/s, 0.24 kg/s and 0.28 kg/s. It was determined that with increase in mass flow rate the outlet temperature of cold water decreased. Higher outlet temperature of cold water was obtained with leaf fins as compared to rectangular, triangular and without-fin cases at mass flow rates of 0.20 kg/s and 0.24 kg/s. The percentage differences in temperature gradient seem to vary with change in mass flow rate. It is shown from the study that the length of heat exchanger with fins could be reduced to half to achieve about 90% of the temperature gradient.

3-D SHAPE MEASUREMENT BASED ON DITHERING TECHNIQUE
Authors: Xincheng Zhao , Yi Zhang , Xin Yan
Published: February 2023

Projector defocusing technique can eliminate projector nonlinearity in real-time three-dimensional shape measurement. However, the high-frequency harmonics brought by defocusing technique weakens the sinusoidal feature of the defocused fringe patterns, which will bring obvious measurement errors. The dithering algorithm is proposed to generate binary fringe, the projector is defocused properly to achieve approximate sinusoidal fringes. This method improves the sinusoidal property of the defocused fringe patterns. Absolute phase is retrieved by applying this method and phase-shifting algorithm. Simulations and experiments are carried out to verify the proposed method, and results show that phase quality has been improved greatly. Compared with existing methods, the proposed method achieves higher precision and can generate fringe patterns more sinusoidal, which is more proper for projector defocusing technique.

Feasibility analysis of replacing lithium-ion battery with aqueous zinc-ion battery
Authors: Tong Yi
Published: February 2023

lithium-ion battery is a battery with intercalated lithium compound as negative electrode material and non-aqueous solution as electrolyte. It is often used as energy supply system for mobile phones, electric vehicles and other equipment. However, due to the instability of lithium and the flammable organic electrolyte, lithium-ion batteries are prone to fire in high temperature or after damage. The paper introduced the technology of aqueous zinc-ion battery and analyzes the merits and drawbacks of it. Aqueous zinc-ion battery is a battery with metallic zinc as negative electrode material. The ingredient of electrolyte is a solution with water as the main component. Compared with lithium-ion battery, it has many excellent characteristics, such as non-toxic, non-flammable, etc. When electronic devices such as smart wearable devices are in close contact with human skin, aqueous zinc-ion batteries can prevent the risk of human skin being burned when the battery damaged or toxic substances penetrating when the battery accidentally leaks. In addition, the high density, high specific energy, much fewer expend and other characteristics of aqueous zinc-ion batteries also increase the possibility that they will replace lithium-ion batteries as energy supply systems for electronic equipment in the future. This paper cites examples to show that the aqueous zinc-ion battery has a good prospect in the field of intelligent wearable devices and has a certain guiding significance for the choice of the energy supply system of intelligent wearable devices in the future.
Batteries on Aircrafts: Challenges & Expectations
Authors: Sun Haolin
Published: February 2023

Growing inconsistency of fossil fuels have generated increased push for new energy researches. Electrifications of transportations are undergoing for ground vehicles and aircrafts. Current developments of electric aircrafts are facing significant challenges that prevents it from becoming a replacement to traditional aircrafts. This paper examines the challenges faced by electric aircrafts and the current progresses made to counter those challenges. Current small electric passenger jets are catching up with fuel jets of similar sizes in terms of their payloads, but still lacking the range and passenger capacity compared to similar fuel jets. Existing batteries are having significantly lower energy density compared to fossil fuels, which limits other performances on an electric aircraft. Developments of new genres of lithium-type batteries with higher energy density is underway. Thermal management of batteries is critical as the high altitude of aircrafts brings low operating temperatures that can be devastating especially for lithium-type batteries. Progresses are being made to seek materials and protections for low temperature applications. With electric motors being the source of propulsions, there is limited improvement on the thrust necessary to power aircrafts. Researches are focusing on improving the aerodynamics of the plane and using turbo-electric propulsion to increase the thrust on the aircrafts. This paper addresses the critical challenges faced by electric aircrafts and offers potential directions, based on existing progresses, for researches on these matters.

In order to promote the development of new energy vehicles, it is very necessary to develop battery packs with high capacity and high safety performance. For achieving this goal, developing new negative electrode materials has proved to be an effective strategy. Among the many candidate materials, lithium titanate has received extensive attention due to its zero strain property. However, the size control of lithium titanate has become a very important factor to improve battery performance. By reducing the particle size, the growth of lithium dendrite can be suppressed and the ion utilization efficiency can be improved. Nanotechnology has been proved to be an effective way to create nano-scale Li4Ti5O12. By optimizing the preparation process parameters, the size of lithium titanate can be controlled within the desired range In recent years, there are many reports about nano LTO technology. In order to have a comprehensive understanding of this field. This paper summarizes and analyzes the development status and future development direction of nanotechnology and lithium titanate battery, the application of nanotechnology in LTO such as sol-gel, molten salt, microwave, hydrothermal and solvothermal synthesis, including the latest synthesis method in recent years, and illustrated the structure-property relationship between Li4Ti5O12 and LTO performance, which provides theoretical guidance for the development of the battery field.
