The meanings of the mysterious number 137
Authors: Bacchieri Alfredo
Published: June 2022

The fine-structure constant inverse is 1/α ≅ 137.036. Both the Nobel Prize winners, Pauli and Feynman, became fascinated by the number 137; anyhow, physicists have not yet found any relation between such number and any other physical law. Here the integer 137 has several clear meanings, on the bases of the following two premises: 1) Form of light: longitudinal massive particles (photons) having length λ=c/v with v their frequency, namely the number of photons, of the same ray (continuous succession of photons), crossing a given observer in a time unit. 2) Electron structure: its charge is not uniformly distributed, but it can be considered as a point particle fixed on the electron spherical surface and facing the atom nucleus during the electron orbits; the electron charge also corresponds to the photons-electron impact point, where photons are absorbed and released. On the above bases, on H atom we found the following main results: n = 1, 2, ..137 electron different circular orbits with n2 the number of admitted photons along two equal circular orbits; v=αc electron charge ground-state (g-s) orbital speed; r= α/4πRH electron charge g-s orbit, with RH the Rydberg constant; v = c/137 exact, electron g-s orbital speed. As for the claimed fall of circling electrons into their nucleus due to their supposed photons emission, we found that the electrons are emitting the previously absorbed photons only during their spiral path toward lower orbits.

Authors: Wang Meng , Gao Feng , Gu Jinguang
Published: June 2022

Task-oriented dialogue systems aim to engage in interactive dialogue with people to ultimately complete specific tasks. Typical application domains include ticket booking, online shopping, and healthcare providing. Medical dialogue systems can interact with patients, provide initial clinical advice, and improve the efficiency and quality of healthcare services. However, current medical dialogue systems lack the ability to utilize domain knowledge. This paper extracts regular domain knowledge as well as medical process knowledge from clinical guidelines to improve the performance of dialogue systems. Regular knowledge is used to generate accurate responses for a given input, and process knowledge is used to steer the conversation. The authors divide the task of multi-turn conversation generation into four sub-tasks and propose a 4-layer knowledge-based process-aware dialogue model that incorporates the domain knowledge to generate responses. Results indicate that the approach can lead medical conversations actively while providing accurate responses.

Authors: Cao Xiaojing , Jin Longxing , Huang Fuquan , Liu Zijun , Xiu Rongkun
Published: June 2022

The early Poisson distribution and Markov autoregressive models can no longer reflect the characteristics of smart grid business flow. The long correlation characteristics of burst flow are simulated by the heavy tail ON/OFF model with multi-source convergence, while the Poisson model with short correlation and no memory is used for random flow. The simulation results show that the synthesized flow is still has a certain statistical self-similarity, and the coefficient H decreases after synthesis.That the long correlation and burst of self-similar business flows will not be smoothed by the convergence and synthesis of the self-similar business flows with short correlation services. In the actual operation process, the station-level power grid will result in load aggravation and significantly affect the network performance when it acts in response to faults. Therefore, it is necessary to consider the changes of network performance under different burst degrees.

Authors: Kaplan Müslüm , Krause Beate , Pötschke Petra
Published: June 2022

Textile products are of great importance in the dissemination of newly developed communication devices and flexible electronics in conjunction with the advantages of covering the entire human body and being used all day long by all individuals in society. Various approaches have been developed to ensure the required electrical conductivity of textiles. Our research deals with melt spinning of carbon nanomaterial-based composites (CNCs) into electrically conductive filaments. By combining the various composite structures and property profiles with a conductive filler at high concentration, specific morphological structures can be achieved that offer a much higher potential for the development of new functional fibers for different smart textile applications.This study aims to produce nanocomposites from polyamide 6 (PA6) and polyethylene (PE) matrices with single-walled CNTs (SWCNTs) and multi-walled CNTs (MWCNTs) by using a small-scale mixing device that provides short mixing time, and material savings in the first stage of the research.

Authors: Frajová Jaroslava , Opálková Šišková Alena
Published: June 2022

In modern society, it is impossible to imagine life without plastics. However, managing the waste composed of plastics is one of the most significant environmental issues confronting us today. Recycling plastic waste or recovering the secondary raw materials sources is the most crucial action available to reduce ecological impacts worldwide. With the need to recycle plastic waste, questions also arise about applying new products from recycled plastics and advanced processing technologies. Advanced technologies overlap actively with the applied design, and their implementation enables them to move from extraordinary design ideas to the final object. Therefore, this contribution shows the possibility to prepare the unique textile pattern, interior accessories, and jewelry from the post-consumer use bottle poly (ethylene terephthalate) (PET) by electrospinning.

Authors: Solanki Utkarshsinh , Viková Martina , Vik Michal
Published: June 2022

The main objective of this work is to study the fatigue behavior of photochromic textiles under different UV irradiance times and develop a rapid testing method. When considering their possible applications, the fatigue resistance of photochromic materials has been considered. The photochromic woven fabric was prepared using the screen-printing method. Previous studies have demonstrated the sensitivity of photochromic pigments to UV radiation's intensity during the experiment. This work provides different thoughts in testing the fatigue resistance of spiro-indolines-based pigment applied on textile fabric. We found that color intensity performance and photodegradation of the photochromic pigment can be evaluated using a relatively small amount of necessary irradiation cycles and an advanced setup of time/intensity UV radiation exposure. Keywords: Color intensity, Fatigue resistance, Photochromic phenomena, UV irradiance time
Antibacterial Nonwoven with Propolis for Use in Surgical Masks
Authors: Aral Nebahat , Yigit Idil
Published: June 2022

Microorganisms that accumulate on the surfaces of protective mask surfaces increase the risk of the spread of infection. In the study, it is aimed to form antibacterial polypropylene (PP) nonwovens treated by propolis extracts for surgical masks. Propolis, which is biocompatible and known to be effective against many bacteria and other microorganisms, was preferred instead of metal compounds with toxic potential. In the study, two types of propolis extracts were used which were prepared in different solvent environment (50% ethyl alcohol - 50% pure water; 47% propylene glycol - 53% pure water). The amounts of phenolic compounds in the solutions obtained differently depending on the solvent and HPLC-DAD analysis of the extracts was performed. After the application of propolis extracts to PP nonwovens by immersion method, the change in their antibacterial activities were measured. According to the results, PP nonwovens with propolis show antibacterial activity against Enterococcus hirae, Escherichia coli, and Staphylococcus aureus. On the other hand, it was observed that the samples that were washed after drying (at 120 °C) lost their antibacterial effect. It is thought that the reason for this situation is that the phenolic compounds in propolis extracts, which are not fully adhered to PP fibers and soluble in water, are removed from the surface by washing.

Published: June 2022

Nowadays, building insulation must be more and more effective to avoid energy loss. This can result in the lack of ventilation which can cause an increase in the concentration of pollutants in the indoor air, such as Volatile Organic Compounds (VOCs) which are harmful to human health. Different approaches have been proposed to reduce this problem such as ventilation, filtration, depolluting plants, etc. The aim of this study consists of developing functionalized textile substrate allowing the VOCs degradation, ideally into H2O and CO2, by the photocatalytic effect under visible light. It is necessary to have photocatalytic activity under visible light for indoor applications as the UV light is filtered by window glasses. To achieve this objective, firstly the samples of woven cotton fabrics are functionalized with the dispersion of silver doped/non-doped TiO2 in Carboxymethyl Cellulose (CMC) and water by padding process. After that, the treatment sustainability of the functionalized fabric is determined.
Dynamic Qualities of Smart Textiles: Study of Stimuli Magnitude with Chromic Pigments
Authors: Cabral Isabel , Souto António Pedro
Published: June 2022

Smart textile behaviour encompasses changes over time, which are triggered upon a sensed stimulus. With a focus on dynamic qualities, this research sought to study how gradual and reversible transitions of smart textiles can be influenced by the activation variable – stimuli magnitude. Taking into account an analysis of different external stimuli for the same property change, the experimental work was conducted with Colour Change Materials, namely textiles screen printed with thermo, photo and hydrochromic pigments. The results attained demonstrate how stimuli magnitude can affect textile temporal expressions, in this case: hue, saturation and lightness, as well as pace change. In addition, different considerations also arose in respect to each stimulus’ energy type and interdependencies between stimuli types. Contributing to the understanding of dynamic qualities of smart textiles and chromic materials’ properties, this research also discusses further alternatives to explore textile behaviour towards new design possibilities for smart textiles as dynamic interfaces.
Textile Heat Flux Sensor Used in Stress Detection of Children with CP
Authors: Tlemsani Fatima Zohra , Gidik Hayriye , Mohsenzadeh Elham , Dupont Daniel
Published: June 2022

This work is part of the European project MOTION (Interreg 2 Seas Mers Zeeën), which aims to develop an exoskeleton for children with cerebral palsy (CP). The developed exoskeleton is equipped with a smart garment in order to detect the stress (e.g. physical, physiological) during the rehabilitation. Five different sensors, i.e. electrocardiogram (ECG), respiratory rate (RR), pressure, galvanic skin response (GSR) and textile heat fluxmeter (THF), are integrated into this smart garment for stress detection. This paper focuses on the development of the textile heat fluxmeter. Several researchers used heat fluxmeters in physiological studies to measure the body heat exchanges with the environment. However, the non-permeability of such fluxmeter gives inaccurate measurements in wet condition. Innovative flexible textile heat fluxmeter may detect, analyze, and monitor the heat and mass transfers with minimum disturbance due to its porosity. Moreover, it is desirable to have flexible sensors when they need to be in contact with the human body, in which the flexibility and non-irritability requirements are of utmost importance.
Dispenser Printing with Electrically Conductive Microparticles
Authors: Lempa Evelyn , Rabe Maike , Van Langenhove Lieva
Published: June 2022

Electrically conductive textiles for wearable smart devices are in increasing demand [1]. The advantages of flexible fabric structures are combined with electronic functions, such as sensing or actuating, energy harvesting or illuminating, for the design of a multitude of smart textiles. Those functions are often created by applying conductive layers or patterns onto the textile surface with two-phase systems based on conductive filler particles in polymeric binders. However, those systems alter the textile-typical properties regarding haptic, drape, flexibility or weight, depending on the type of conductive particle used, i.e., metal-or carbon-based ones. Generally, electrical conductivity increases with the increase of conductive filler concentration. The relation between the various factors determining the electrical behavior as well as the percolation threshold for some dispersions and in particular the size and shape of the filler particles were previously assessed for planar coatings [2]. In this research work electrically, conductive patterns were printed with dispenser printing technology using such two-phase dispersions based on polyurethane and polyacrylate binders and various metal microparticle flakes. With this application method linear resistance of approx. 25 to 100 Ohm per 100 cm depending on the textile structure could be realized, which was not even significantly reduced by household washing at 40°C or abrasion by Martindale.
Flutamide-induced hepatotoxicity: A case report
Authors: Kassid Omer M. , Odhaib Samih A. , Altemimi Mahmood Thamer
Published: June 2022

Flutamide is a non-steroidal anti-androgen drug effective in the management of prostatic carcinoma. The drug appears to be well tolerated with mild gastrointestinal adverse events and gynecomastia. Flutamide-induced hepatotoxicity may range from minor elevation in liver enzymes to hepatic failure. Here, we tried to discuss the possibility of hepatotoxicity induced by flutamide as antiandrogen therapy in a patient with prostatic adenocarcinoma. Here we present a 75-year-old man who commenced flutamide as a postoperative anti-androgen for prostatic adenocarcinoma for two months. He had markedly elevated levels of liver enzymes due to acute liver failure and subsequent multi-organ failure. The patient died after the failure of the resuscitation measures. The temporal relationship between the flutamide initiation and the emergence of hepatotoxicity is not clear, with a possible latency of 12-16 weeks. Careful monitoring of liver function test during flutamide therapy is essential to prevent serious hepatotoxicity.
A retrospective analysis of 47 procedures using a bioresorbable polycaprolactone based injectable for the treatment of mild to moderate stress urinary incontinence in adult females
Authors: Mojsović Anđelo , Koldewijn Evert
Published: June 2022

Over the recent years, potential longterm complications of permanent implants for urinary incontinence has become a topic of debate. As a result there is an increasing interest in less invasive and bioresorbable procedures from both healthcare professional as well as patients that ideally can be performed in an out-patient setting. This brief report describes our initial results using a novel bioresorbable injectable product for the treatment of female mild to moderate stress urinary incontinence. The results show that the majority of patients respond well to treatment and remain continent for the initial 12 months following injection. Complication rate is low and consisted of mild and transient events. These initial results are promising and merit further investigation into using this procedure as first-choice after unsuccessful conservative treatments such as pelvic floor muscle therapy.
Comparison of Dyspnea, Acidosis, Consolidation, Acidaemia, and Atrial Fibrillation Score and BAP-65 Score as Tools for Prediction of Mortality and Morbidity in Acute Exacerbations of Chronic Obstructive Pulmonary Disease at a Tertiary Care Hospital
Authors: Nagaraja B. S. , Menon Anindita , Chandrashekar Arjun P.
Published: June 2022

Background:

According to the Global Burden of Disease 2018, chronic obstructive pulmonary disease (COPD) is the third-leading cause of death worldwide and in India COPD is the second leading cause of death among noncommunicable diseases. Tools to predict mortality in stable COPD are widely in use but there has been lack of research into exacerbations and finding an appropriate clinical tool could help to reduce morbidity and mortality in these cases.

Aims

1. To assess dyspnea, acidosis, consolidation, acidaemia, and atrial fibrillation (DECAF) score and Blood Urea Nitrogen, altered mental status, pulse > 109 beats/min, age > 65 years (BAP- 65) score in acute exacerbations of COPD. 2. To compare the DECAF score and BAP-65 score as predictors of in-hospital morbidity and mortality.

Subjects and Methods

The study was a prospective observational study carried out on 80 patients with acute exacerbation of COPD admitted to Bangalore Medical College and Research Institute from November 2018 to May 2020. Detailed history, physical examination, and standard laboratory tests were done on admission. Patients were assessed by the DECAF and BAP-65 (blood urea nitrogen, altered mental status, pulse, age ≥65 years) scores. The outcomes in terms of mortality and need for mechanical ventilation were studied and comparisons were drawn between the two scores.

Results

From 80 AECOPD patients, 8 patients died and 72 survived. Significant difference was found in dyspnea grade eMRCD 5b (P = 0.038), eosinopenia (P = 0.036), pH <7.3 (P < 0.001), and consolidation (P = 0.027) between survivors and patients who died. With the rise in total DECAF score mortality rose (P < 0.001). When the individual components of the BAP-65 score were compared there was no statistically significant difference. With rise in the total BAP-65 score, there was no significant difference in mortality (P = 0.09). Sensitivity for prediction of mortality for DECAF score and BAP-65 score was 88.9% and 81.7%, respectively, and specificity was 55.4% and 63.4% respectively. Sensitivity for prediction of need for mechanical ventilation for DECAF score and BAP-65 score was 83.3% and 83.8%, respectively, and specificity was 66.7% and 66.2%, respectively.

Conclusions

In our study, we found the DECAF score to be a better predictor of mortality and need for mechanical ventilation than the BAP-65 score as it is a composite score taking into account various parameters such as acidosis, consolidation on imaging, and eosinopenia each of which are individually strong predictors of mortality.
A Case of Isolated Primary Muscular Tuberculosis of the Gluteal Region
Authors: Pandiaraja Jayapal , Shalini Arumugam
Published: June 2022

Muscular tuberculosis is one of the rare types of tuberculosis, with an incidence of around 0.01%–1%. Muscular tuberculosis can be primary or secondary. Primary muscular tuberculosis can be due to direct trauma or direct inoculation of tuberculous bacilli. Secondary muscular tuberculosis is a part of disseminated tuberculosis. Our patient was initially diagnosed with pyogenic abscess and treated, but the patient failed to respond and later presented with multiple abscess cavity. Biopsy from the cavity wall proved as muscular tuberculosis and the patient responded well to anti-tuberculous treatment. Muscular tuberculosis must be considered one of the differential diagnoses for the patient with multiple gluteal discharging sinuses. The best investigation to confirm muscular tuberculosis is histopathological confirmation of granuloma.
Dermatological adverse events of cancer chemotherapy
Authors: Awal Guneet , Singh Guramrit
Published: June 2022

Introduction:

Although newer chemotherapeutic drugs prolong patients’ survival, they cause a myriad of dermatological adverse effects leading to decreased quality of life.

Aims and Objectives:

The study was undertaken to assess the various cutaneous adverse effects associated with chemotherapeutic drugs.

Materials and Methods:

A total of 736 diagnosed cancer patients on chemotherapy attending the dermatology department of a tertiary care center were studied in this observational study between June 2019 and May 2021. Detailed dermatological examination to include skin, hair, nail, and mucosal changes was undertaken after informed consent.

Results:

The most common malignancy observed was breast carcinoma, which was seen in 21.33% of the cases. It was followed by carcinoma cervix in 12.09% of the cases. Most commonly implicated drugs were platinum therapy (cisplatin, carboplatin) and anthracyclines (doxorubicin and epirubicin). Alopecia was the most common adverse effect seen in 55.84% of the patients. It was followed by hand-foot syndrome in 11% of the patients. Nail changes were seen in 4.21% of the patients, and the most common nail finding was longitudinal melanonychia seen in 1.49% of the patients.

Conclusion:

Knowledge regarding occurrence and severity of dermatological side effects of chemotherapy aids in early recognition and treatment. It also benefits in educating patients regarding potential adverse effects, taking appropriate prophylactic measures, and therefore better compliance by the patient.
Screening for postpartum depression by health-care workers in Kaduna, North-Western Nigeria
Authors: Mohammed-Durosinlorun Amina , Mamoon Nafisatu , Yakasai Bashir A.
Published: June 2022

Background:

Postpartum depression (PPD) can be associated with adverse maternal/neonatal outcomes and screening leads to increased recognition and earlier initiation of management before more complications set in.

Objectives:

The objective of the study was to determine practices and attitudes towards screening for PPD among health care workers in Kaduna.

Methods:

The study was a cross-sectional descriptive study. Participants were health-care workers providing care for pregnant women. A pretested semi-structured questionnaire was used for data collection. Information collected included biodemographic data, professional and hospital characteristics, knowledge, views, and practices related to PPD screening. Data were summarized using cross table and frequency tables. Chi-square or Likelihood Ratio test was used as appropriate. A P < 0.05 was considered statistically significant.

Results:

There were 202 respondents. The mean age of participants was 34.49 ± 9.95 years. Majority of the participants had experience of 1–5 years (53, 26.2%), worked in secondary (80, 39.6%), and public (168, 83.2%) facilities. Most participants “Sometimes” or “Never” screened women for PPD (184, 91.1%), while 18 participants (8.9%) “Always” or “Often” screened for PPD. Facility level and cadre were significantly associated with routine screening for PPD (P < 0.05). Only about 10% were aware of the use of validated questionnaires as screening tools. Overall, one hundred and seventy-six participants (87.1%) had a good attitude toward screening for PPD. Religion and ethnic group were significantly associated with attitudes toward PPD screening.

Conclusion:

Most respondents do not routinely screen women for PPD and are not very familiar with screening tools but had good attitudes toward PPD screening.
Pus cell as an indicator for Mycobacterium tuberculosis diagnostic yield by GeneXpert MTB/RIF in South-South Nigeria
Authors: Edem Ekom Ndifreke , Umo Anthony Nathaniel , Akinjogunla Olajide Joseph , Akereuke Unwana Ezekiel
Published: June 2022

Background:

The common problem in tuberculosis (TB) management is mis-diagnosis or under diagnosis of cases leading to high morbidity and mortality. In order to reverse this, new diagnostic tools for detection of Mycobacterium tuberculosis (MTB) have been developed. However, in the evaluation process of these tools many studies have not considered attributes of sputum quality in their testing algorithm. The performance of laboratory tests to diagnose pulmonary tuberculosis is dependent on the quality of the sputum sample tested and quality is measured by the number of pus and epithelial cells present in sputum. Aims and Objectives: this study aimed at investigating the association between pus cell and MTB positivity.

Methods:

Sputum samples from 140 suspected TB participants were screened for sputum quality and MTB using macroscopy, Ziehl-Neelson staining and GeneXpert techniques.

Results:

Of the 140 sputum samples subjected to AFB microscopy and GeneXpert MTB/RIF assay, GeneXpert assay had 32 (22.9%) MTB positives while AFB smear had 27 (19.3%) MTB positives and there was no significant relationship between sputum type and MTB yield by AFB compared to Xpert that showed significant relationship between sputum type and MTB yield with P<0.005. Out of the 37 sputum samples with pus cells ≥25, 29 (90.6%) were MTB positive by Xpert and 25 (92.6%) were MTB positive by AFB smear.

Conclusion:

In conclusion, our study shows a high significant association between pus cells presence and the methods and therefore suggests that presence of pus cells in sputum is predictive for possible positivity to MTB by Xpert MTB/RIF.
The DRACO Stream Cipher
Authors: Hamann Matthias , Moch Alexander , Krause Matthias , Mikhalev Vasily
Published: June 2022

Stream ciphers are vulnerable to generic time-memory-data tradeoff attacks. These attacks reduce the security level to half of the cipher’s internal state size. The conventional way to handle this vulnerability is to design the cipher with an internal state twice as large as the desired security level. In lightweight cryptography and heavily resource constrained devices, a large internal state size is a big drawback for the cipher. This design principle can be found in the eSTREAM portfolio members Grain and Trivium.Recently proposals have been made that reduce the internal state size. These ciphers distinguish between a volatile internal state and a non-volatile internal state. The volatile part would typically be updated during a state update while the non-volatile part remained constant. Cipher proposals like Sprout, Plantlet, Fruit and Atom reuse the secret key as non-volatile part of the cipher. However, when considering indistinguishability none of the ciphers mentioned above provides security beyond the birthday bound with regard to the volatile internal state. Partially this is due to the lack of a proper proof of security.We present a new stream cipher proposal called Draco which implements a construction scheme called CIVK. In contrast to the ciphers mentioned above, CIVK uses the initial value and a key prefix as its non-volatile state. Draco builds upon CIVK and uses a 128-bit key and a 96-bit initial value and requires 23 % less area and 31 % less power than Grain-128a at 10 MHz. Further, we present a proof that CIVK provides full security with regard to the volatile internal state length against distinguishing attacks. This makes Draco a suitable cipher choice for ultra-lightweight devices like RFID tags.
Automatic Search of Rectangle Attacks on Feistel Ciphers: Application to WARP
Authors: Lallemand Virginie , Minier Marine , Rouquette Loïc
Published: June 2022

In this paper we present a boomerang analysis of WARP, a recently proposed Generalized Feistel Network with extremely compact hardware implementations. We start by looking for boomerang characteristics that directly take into account the boomerang switch effects by showing how to adapt Delaune et al. automated tool to the case of Feistel ciphers, and discuss several improvements to keep the execution time reasonable. This technique returns a 23-round distinguisher of probability 2−124, which becomes the best distinguisher presented on WARP so far. We then look for an attack by adding the key recovery phase to our model and we obtain a 26-round rectangle attack with time and data complexities of 2115.9 and 2120.6 respectively, again resulting in the best result presented so far. Incidentally, our analysis discloses how an attacker can take advantage of the position of the key addition (put after the S-box application to avoid complementation properties), which in our case offers an improvement of a factor of 275 of the time complexity in comparison to a variant with the key addition positioned before. Note that our findings do not threaten the security of the cipher which iterates 41 rounds.
New Key-Recovery Attack on Reduced-Round AES
Authors: Ghaedi Bardeh Navid , Rijmen Vincent
Published: June 2022

A new fundamental 4-round property of AES, called the zero-difference property, was introduced by Rønjom, Bardeh and Helleseth at Asiacrypt 2017. Our work characterizes it in a simple way by exploiting the notion of related differences which was introduced and well analyzed by the AES designers. We extend the 4-round property by considering some further properties of related differences over the AES linear layer, generalizing the zero-difference property. This results in a new key-recovery attack on 7-round AES which is the first attack on 7-round AES by exploiting the zero-difference property.
Integral Cryptanalysis of WARP based on Monomial Prediction
Authors: Hadipour Hosein , Eichlseder Maria
Published: June 2022

WARP is a 128-bit block cipher published by Banik et al. at SAC 2020 as a lightweight alternative to AES. It is based on a generalized Feistel network and achieves the smallest area footprint among 128-bit block ciphers in many settings. Previous analysis results include integral key-recovery attacks on 21 out of 41 rounds. In this paper, we propose integral key-recovery attacks on up to 32 rounds by improving both the integral distinguisher and the key-recovery approach substantially. For the distinguisher, we show how to model the monomial prediction technique proposed by Hu et al. at ASIACRYPT 2020 as a SAT problem and thus create a bit-oriented model of WARP taking the key schedule into account. Together with two additional observations on the properties of WARP’s construction, we extend the best previous distinguisher by 2 rounds (as a classical integral distinguisher) or 4 rounds (for a generalized integral distinguisher). For the key recovery, we create a graph-based model of the round function and demonstrate how to manipulate the graph to obtain a cipher representation amenable to FFT-based key recovery.

“TÁ VENDO O QUE EU TÔ FALANDO?” Reflexões sobre a escuta ativa e as performances da voz no contexto educacional durante a pandemia da Covid-19
Authors: Contreiras Melissa
Published: June 2022

A transformação experienciada no ambiente educacional em decorrência da pandemia do coronavírus em 2020 foi marcada pela impossibilidade da interação entre os corpos. O imediato estranhamento ocorrido em decorrência dessa situação e a apreensão da sala de aula como um lócus privilegiado para o entendimento da relação entre os sentidos, possibilitaram-me refletir sobre a relação entre a visão e a audição a partir de sua construção histórica e cultural. As aulas, acontecendo de modo remoto e algumas das estratégias didáticas — como o uso de podcasts —, desenvolvidas pelas professoras as quais tive a oportunidade de acompanhar no exercício de sua profissão, ensejaram uma análise a respeito do que optei por chamar de performances da voz no contexto educacional e do próprio processo de ensino-aprendizagem.

Turkey as a Transport Hub: a Vision Strategy for Integrating Regional Infrastructures and Services
Authors: Gabrielyan Hayk
Published: June 2022

Surrounded by seas on three sides, Turkey wants to connect different seas and coastal regions by land transport corridors. Moreover, Turkey pretends to connect the Pacific, Atlantic, Indian and also Arctic Oceans by various transport corridors, which may referred to China, the EU, India and Russia accordingly. Thus, Turkey's transport strategy has 3 levels: national, regional and international.
The research objective is to reveal Turkey's prospects of becoming a transport hub, to analyze Turkey's geographical location, the favorable circumstances and obstacles, the positions of the Turkish leadership and regional and extra-regional actors. We conclude that Turkey has glimmering chances to become a transport hub both in the West-East and North-South directions, and even in their various branches.
Becoming a transport hub is very important from Turkey's point of view to be included in the top ten economically leading countries․ Likewise, it full compliances with Turkey's current ambitions։ Turkey is already a regional superpower with global ambitions, and in the long-term perspective it aspires to become a global player.
The topic is actual for Armenia, as it directly refers on it․ The aspiration of Turkey to become a transport hub can also put Armenia on the world transport map, turning it into a transport hub as well, at least in the East-West (China-Europe) direction.

While the majority of Armenian scholars are convinced the status of Nagorno-Karabakh should be based on the implementation of the right of self-determination, very little attention has been paid to the issue of the legitimacy of the pre-war borders of the Republic of Artsakh. Roughly, it is possible to divide the positions of the Armenian expert community into those who believed some or most of the seven districts will be ceded to Azerbaijan as a result of negotiations and those who deemed any attempt to change the pre-war status-quo as either dangerous, strategically flawed, unnecessary, groundless or downright betrayal of national interests and the century-long struggle for the integrity of Artsakh and Armenia. However, the evolution of the state of the de-facto Republic of Artsakh in the context of the legitimacy of its pre-war borders has received scant, if any, academic attention. It is this side of the matter that we attempt to address in this article through the lens of territoriality and the critical review of the so-called Madrid Principles.

Authors: Sargsyan Arnak
Published: June 2022

In the study of the perceptions of post-Soviet political participation, the article substantiated the study of the issue of political participation, the theoretical bases of the analysis of political participation in the stage of democratic consolidation. We concluded that due to the transformation of the society, non-traditional participatory actions are becoming more widespread, which largely testifies to the high level of civic consciousness of the society. Political participation is an institutional mechanism for establishing a democratic state and implementing policy, studying the activities of policy actors in different manifestations of behavior. It is very important that everyone involved in social and political life has some knowledge of the culture of participation, social and psychological training. In the conditions of globalization, it is impossible to imagine the establishment of a democratic political system without the realization of citizens’ rights.

Despite it, ideal geographic location, salubrious climate and Samhita based approach are the other key factors. Other potential and developing fields in Ayurveda for Health Tourism are Swasthvritta (lifestyle modification), Pathya-apathya (dietary habits/Nutrigenomics), Garbha Sanskara (having a healthy and desired progeny), infertility management, Rasayana (rejuvenation), Vajikarana (aphrodisiac) etc. Ayurvedic medicines are herbal or herbo-mineral. Lack of identification, availability, proper collection and processing of herbs are the major hurdles that lead to contamination and affect the potency of preparation. Mineral compounds must be processed strictly following the guidelines mentioned in Ayurvedic texts. Otherwise, heavy metal contaminants left in the preparation might cause metal toxicity in consumers. Strict adherence to “Drug Standardization Protocols” is the need of hour by drug manufacturing units to remove the taboo of metallic toxicity and placebo for Ayurvedic preparations globally.

These stones are formed when the urine becomes excessively supersaturated with respect to a mineral, leading to crystal formation, growth, aggregation and retention within the kidneys that develop in the urinary tract and are known as Nephrolithiasis or Urolithiasis. Though multiple and advanced treatments are available to treat the renal stones, complete relief and non recurrence is still not possible. In Ayurvedic science, renal stones or the urolithiasis can be correlated to Mutrashmari, which is said to be a disease of Mutravaha srotas. Though various types of treatments are available in the classics, the unique oral medication known as Paneeya kshara or the oral medication prepared out of alkaline substances is described by Acharya Susrutha in Sushrutha samhitha for the successful management of Mutrashmari.
