In part two we develop and end to end driving model based on CNNs to learn from the drivers driving data and can drive the car with only the camera data from on-board cameras. Performance of the proposed system is observed by the implementation of the autonomous car that can be able to detect and classify the stop signs and other vehicles.
Artificial Intelligence-Based Network Selection and Optimized Routing in Internet of Vehicles
Authors: Hussain Shaik Mazhar , Yusof Kamaludin Mohamad , Hussain Shaik Ashfaq
Published: November 2021

Internet of Vehicles (IoV) is a network of vehicles communicating with each other by exchanging road traffic information via radio access technologies. Two potential technologies of V2X that have gained attention over the past years are DSRC and cellular networks such as 4G LTE and 5G. DSRC is suitable for low latency communications, however provides a shorter coverage range whereas, 4G LTE offers a wide coverage range but has high transmission time intervals. In contrast, 5G offers higher data rates, low latencies but prone to blockages. Single technology might not fully accommodate the requirements of vehicular communications. Hence, it is required to interwork with more than one radio access network to satisfy the requirements of safety vehicular applications. One issue identified when working with multiple radio access networks is the selection of the most appropriate network for vertical handover. Usually, in the previous works, the network is selected directly or will be connected to the available network due to which the handover had to take place frequently resulting in unnecessary handovers. Hence, in the existing state-of-the-art, the need for handover is not validated. In this paper, we have proposed a dynamic Q-learning algorithm to validate the need for handover, and then, appropriate selection of network would take place by using a fuzzy convolutional neural network. Besides, a modified jellyfish optimization algorithm is proposed to select the shortest paths by forming V2V pairs that take into account channel metrics, vehicle metrics, and vehicle performance metrics. The proposed algorithms are then evaluated using OMNET++ and compared with the existing state-of-the-art concerning mean handover, HO failure, throughput, delay, and packet loss as the performance metrics.
Method of Assessing the Efficiency of Electrical Power Circuit Separation with the Power Line Communication for Railway Signs Monitoring
Authors: Kiedrowski Piotr , Saganowski Łukasz
Published: November 2021

The article describes a project to use PLC technology in railway light signs. The proposal presents a solution for the separation of supplying circuits with the use of filters. The necessity of separation is a result of long distance data transmission between sign controllers and LED railway signs using PLC modems which work on the same frequency. Problems in the selection of filter parameters are presented due to the fact that there is no specification for the characteristic of the separation filter, there are only requirements for the reliability communication system. To meet these requirements, the circuits separation efficiency must be assessed. The paper presents a quick method to evaluate separation efficiency. Structure of the network, as well as the set of devices which realize this specific kind of wired sensor network for supervising railway LED sign network and maintenance parameters are also presented in this article.

Published: November 2021

Unlike literature and studies coming from high-income or Western countries, the existing conducted on the Middle East and North Africa fail to draw a nearly complete image of the characteristics of passenger travel behaviors in the urban areas of the region. This gap necessitates a holistic review of the previous studies and comparing their results of those of the international findings. This paper summarizes the status of urban travel behavior studies on the MENA region under eight categories of socioeconomics, land use, perceptions and attitudes, urban sprawl, neighborhood design, public transportation use, active mobility, and new technologies and concepts. Descriptive literature review and desk research depicts both lack of research results or data and differences between the behaviors in the MENA region and the Western countries. Moreover, based on the background review, this paper provides a list of recommendations for having more sustainable mobility in the MENA region.

Published: November 2021

The technical conditions and service life of steering elements of vehicles are an important factor directly affecting road safety. Therefore, high reliability of such kind’s components is required. In the paper, on the basis of the stand test, the fatigue durability of a ball joint of a steering tie rod is determined. It is elaborated together with a prediction for the further number of cycles, enabling to determine the technical state of the tested component containing its service life. The aim of the article is to select an appropriate mathematical model with respect to describing the relationship between the moment of force and the fatigue cycles performed for the ball joint of a steering rod of a vehicle with a GVW above 3.5 tonnes, and identifying the model’s parameters. As a result, the limit number of loading cycles after which the examined joint does not meet safety requirements is estimated.
Design of Low Voltage Quasi-floating Self Cascode Current Mirror
Authors: Anil P. , Tamil S. , Raj N.
Published: November 2021

In this paper, a modified structure of self-cascode structure is proposed. In the proposed structure, the MOSFET working in saturation mode is replaced by a Quasi-floating gate MOSFET by which the threshold voltage can be scaled, resulting in an increase in the drain-to-source voltage of other MOSFET operating in the linear region. The increased drain-to-source voltage results in a change in the operating region, which here is from linear to saturation regime. To exploit the performance of the proposed structure, the design of the current mirror circuit is shown in this paper. The proposed architecture when compared with its conventional design showed improvement in performance without affecting the other parameters. The complete design is done using MOSFET models of 180nm technology using Spice at supply dual supply of 0.5V.
Planning in Times of Uncertainty
Authors: Gonçalves Carla
Published: November 2021

Coastal city-regions are dealing with new wicked problems due to climate change. Therefore, there is a demand for alternative paradigms and methodologies beyond the neoconservative perspective, demanding a transformative planning practice based on a territory-landscape plan as a catalyst for change. Landscape approaches are not ‘new,’ but they have become a driving paradigm in the international realm during the last decades. This paper explores the differences in taking a landscape approach on the Global North and South and discusses how a landscape approach can add value to coastal planning theory, especially when looking for the territories of the 21st metropolis. Conclusions have shown that landscape approaches from both Global North and South can strongly lead to a transformative and adaptive response.

Recent advances demonstrate phytochemicals to be a potent anticancer therapeutic agent as various anti-cancer targets. This study depicts the anti-cancer potential against certain crucial common cancer targets leading to cancer cell proliferation and survival. The main objective of this study is to study the anti-cancer potential of phloretin against certain cancer targets. Ligand analysis was performed and Phloretin was chosen as the experimental ligand and Bcl-2, NF Kappa B, Carbonic anhydrase I (CA-1), Inducible Nitric Oxide Synthase (iNOS), Endothelial Nitric oxide synthase (eNOS), Caspase 3, and Caspase 9 proteins were chosen as targets. Induced fit molecular docking was performed by the use of Glide 6.5 software (Schrodinger - 2015). The docked poses were further evaluated based on binding energy, Conformational changes, and the amino acid residues involved in the protein-ligand interaction. The docking results depicted that phloretin showed notable binding affinity especially with carbonic anhydrase I, ENOS, and INOS. It also showcased significant potential against Caspase 3 and NF Kappa, thereby showing its potential as an effective anti-cancer therapeutics. During this study, the Inhibitory potential of Phloretin was studied as a result of this molecular docking study. This Insilico study revealed the binding efficiency of phloretin against the aforementioned targets. In vitro analysis is required for further validation of this data.

Published: November 2021

Surface preparation of engineering materials is necessary for preventing corrosion and subsequent failure of materials in service. There are different methods of surface preparations that can affect engineering materials in different ways. This study investigated the effect of surface preparation on the corrosion behavior of zinc sprayed and unsprayed mild steel. Quantitative analysis and potentiodynamic polarization techniques were used to evaluate the immersed samples of different surface preparations. The results indicated that the least corrosion rate was observed for the uncoated sample prepared with CC1200 grit paper at 0.041 mpy and successive samples in the order of CC220 grit paper at 0.047 mpy < P60 grit paper at 0.052 mpy < filing at 0.064 mpy and grinding at 0.074 mpy after 42-days of immersion. The prepared samples that were further coated with zinc spray demonstrated a similar trend. The sample prepared with CC1200 grit paper and further coated with zinc spray exhibited the lowest corrosion rate of 1.35 x 10-9 mpy. Potentiodynamic polarization results further suggested that the same behavior was observed in the quantitative analysis.
Bilinguismo eletivo e ensino de língua inglesa no Brasil
Authors: Cunha Adan Phelipe
Published: November 2021

Conceituando o bilinguismo eletivo como a situação em que indivíduos escolhem aprender outra língua (BAKER, 2001), este ensaio defende ser fundamental que o professor brasileiro de inglês se perceba como sujeito bilíngue, para que seja possível reorientar as práticas de ensino desta língua, especialmente nas atuais propostas de educação bilíngue, cada vez mais frequentes no cenário brasileiro. Consideramos que esse professor não costuma se perceber como um sujeito bilíngue, pois se compara ao falante nativo de língua inglesa (cf. GROSJEAN, 1989). A partir do conceito de superdiversidade (VERTOVEC, 2007), convidamos o leitor a repensar o Brasil por uma ótica plurilíngue. Por fim, avaliamos também ser necessário romper com a noção de ensino de “línguas estrangeiras”, substituindo-a pelo conceito de bilinguismo eletivo.

Published: November 2021

The results of the use in the experiment of composite hydrogel coatings of prolonged action based on polyvinyl alcohol are investigated.

Objective. The aim of the study is a comparative clinical assessment of the effectiveness of the developed composite hydrogel coatings of prolonged action in an experiment in laboratory rats.

Materials and research methods. After modeling alloxan diabetes mellitus and neuroischemic form of diabetic foot in laboratory white Wistar rats, the developed wound dressings were applied. A clinical analysis of their effectiveness was carried out and the optimal composition was determined. The animals were divided into three groups, 10 animals in each group, as follows: the first — control with self-healing of the wound, the second — with samples No. 1 (polyvinyl alcohol + chitosan + pectin + L-aspartic acid + gentamicin), the third — with samples No. 2 (polyvinyl alcohol + chitosan + pectin + L-aspartic acid + gentamicin + methyluracil). The first dressing change was carried out on the third day with the taking of histological material, then - every other day. When changing the dressing, such parameters as the nature and amount of wound discharge, the size of the ulcer, the presence of granulations and epithelialization were assessed. Dynamic assessment was performed on the 3rd, 7th, 14th and 21st days. The measurement of the area of the ulcer was carried out by transferring the contour of the ulcer to graph paper with manual counting.

Research results. The healing rate of ulcers in the experimental groups was higher than in the control group. When comparing second and third groups, a significant increase in speed was noted by the seventh day in third group (p < 0.05), which reduced the overall healing time of ulcers by 7 days.

Conclusion. The study showed that the healing time of ulcers in laboratory animals with the use of the developed wound dressings is significantly reduced in comparison with the control group. The proposed method of local treatment can be considered effective in the treatment of vascular etiology trophic ulcers against the background of diabetes mellitus.
The possibility of using autologous adipose tissue for the stage shin wound closing
Authors: Markov S. N. , Spiridonov A. A. , Slepov A. V.
Published: November 2021

Extensive soft tissue defects can be complicated by systemic diseases (trophic ulcers in diabetes mellitus, chronic arterial insufficiency) or the result of trauma (domestic, military, operating, etc.). The current increase in the incidence of this pathology is due to the spread of cardiovascular diseases and diabetes mellitus. Closing an infected long-term non-healing wound, such as a tendon or bone, is one of the most difficult tasks of reconstructive surgery. For example, the use of classical methods of closing wound conditions is difficult to a degree due to the patient's polymorbid background. The clinical case presented in the article shows the possibility of closing deep shin wound with a complex relief by the transplantation of autologous adipose tissue, a patient with severe concomitant pathology.

Published: November 2021

The aim of this study is to compare the somatotype of male running Ultra-trail race at different distances and to evaluate the race performance relationship. A total of 44 runners, average of age 45.64 ± 9.16 years; average of height 175.84 ± 6.18 cm; average of body weight 75.36 ± 7.46 kg, who ran distances of 13 km (n= 6), 30 km (n= 19), 66 km (n= 14) and 100 km (n= 5), participated voluntarily in the study. Heath & Carter method was used to determine the somatotypes of the runners. The running performance times were taken from the race results section on the organization's website. One-way ANOVA test was used to compare the running groups, and the Pearson correlation test was used for correlation analysis (p < 0.05). As a result, there was a significant difference in endomorph (p = 0.000) and mesomorph (p = 0.035) of the groups. Significant differences were observed between the endomorph of 13 km runners compared with 30 km (p = 0.003), 66 km (p = 0.002) and 100 km (p = 0.005) runners. It was found that those who run 13 km had more mass than those who run 30, 60 and 100 km, and as the distance increased, the endomorph and mesomorph values decreased, and the long-distance running athletes had a more linear physical structure. In Ultra Trail runs the somatotype differs according to the distance, and it can be said that the somatotype mesomorphic-ectomorph as the performance time and distance increases.

La théorie du « choc des civilisations » popularisées dans les années 1990 suite à la publication de l’ouvrage de S. Huntington, connait un large succès politique et médiatique qui ne se dément pas malgré de nombreuses critiques. Dans cet article, nous choisissons de considérer comme possible la représentation du monde en aires de civilisations en conflits entre elles et de tester empiriquement son existence dans un corpus de représentations mentales de l’échelle mondiale produites par des étudiants en s’intéressant particulièrement aux individus appartenant aux civilisations définies comme « islamiques » et « occidentales » par S.

Changement pétrographique majeur dans les hautes terrasses de la Meuse entre Namur et Huy (Belgique) à la suite de la capture de la Semois
Authors: JUVIGNÉ Étienne , HOUBRECHTS Geoffrey , CAMPENHOUT Jean VAN
Published: November 2021

Une étude sédimentologique de lambeaux de très hautes terrasses mosanes entre Namur et Huy a permis d’améliorer les connaissances relatives à l’évolution de la Meuse de Dinant qui a façonné des terrasses sur 35 m de dénivelée sous le niveau de la transgression oligocène du plateau en y abandonnant systématiquement un cailloutis épais de quelques décimètres et caractérisé par une large majorité de galets de quartz ainsi qu’une granularité essentiellement inférieure à 32 mm. À l’altitude actuelle de 180 m à Andenne/Huy, un cailloutis grossier et riche en cailloux roulés de quartzite a brutalement envahi le bassin ; il est attribué à la capture de la Semois survenue à Revin (France). Cette capture est placée dans le Pléistocène inférieur sur la base de sa position stratigraphique dans les modèles de terrasse existants, plutôt que dans le Mio-Pliocène comme évoqué dans la littérature.
Remise en question de l’âge de la capture de la Meuse lorraine à la lumière de la répartition des amphiboles des Vosges dans les terrasses mosanes
Authors: JUVIGNÉ Étienne , HOUBRECHTS Geoffrey
Published: November 2021

Les associations de minéraux denses transparents de 25 lambeaux de divers niveaux de terrasses mosanes ont été établies et les résultats antérieurs en cette matière ont été rassemblés. Les amphiboles présentes dans la classe granulométrique de 75 à 425 µm des terrasses de cailloutis mosans proviennent des Vosges, qu’elles soient brunes ou vertes assorties de pléochroïsme. De la sorte, il apparait qu’au cours de l’incision de la Meuse, les amphiboles des Vosges sont entrées en scène dans une terrasse située à 128 m à Givet (+28 m vs plaine d’inondation) et à 134-140 m à Lixhe/Visé (+80 m vs plaine d’inondation). Cette terrasse, par ailleurs en contre-pente, débouche dans le profil de référence de Maastricht au niveau de la Terrasse de Valkenburg-1 pour laquelle il existe une estimation d’âge de 1,57 Ma. La capture de la Meuse lorraine aurait donc eu lieu dans la seconde moitié du Pléistocène inférieur et non pendant la transition mio-pliocène comme avancé dans la littérature la plus récente.
Comprendre les comportements des populations en situation de risque naturel dans les pays en développement : exemple de Douala (Cameroun)
Authors: TCHOUNGA Gille Baustert
Published: November 2021

Dans les pays en développement, la gestion des risques naturels par les ménages met en exergue des réactions sociales dont la compréhension reste complexe. Comment le risque est-il pensé dans un contexte de précarité ? Qu’est ce qui détermine les actions des ménages en situation de risque naturel ? À partir des enquêtes de terrain et des modèles théoriques en sciences sociales (capabilités et motivation à la protection), cet article relève les déterminants de l’adoption des comportements préventifs en situation de catastrophe naturelle dans la ville de Douala. Plusieurs éléments contextuels motivent les actions des ménages dans les zones à risque, l’analyse conduit à deux attitudes adoptées à la suite du processus perception-représentation-comportement : les initiatives protectrices liés à la minimisation du risque et celles non protectrices liées au déni et au sentiment de sécurité. Le renforcement de la communication sur les risques naturels constitue une dimension indispensable à considérer dans la gestion durable des territoires exposés aux risques naturels.
La pêche thonière au Gabon : entre exploitation et nécessité d’industrialisation locale

Published: November 2021

L’exploitation du thon au Gabon fait l’objet d’une pêche sous accords privés ou de partenariats depuis plusieurs décennies. Aujourd’hui, avec la prise en compte du domaine maritime dans le Programme Stratégique Gabon Emergent (PSGE), cadre de référence des politiques publiques depuis 2009, la pêche thonière suscite un intérêt soutenu de la part de l’État. Ce dernier ambitionne de renforcer les contrôles en mer, dans la perspective de développer une filière industrielle locale et de trouver un équilibre durable pour les stocks thoniers. Cet article met exergue la problématique de « l’or bleu » dont la maîtrise constitue une source réelle de protéines animales, de dividendes et de diversification économique. De fait, il est particulièrement question de s’appesantir sur les thons tropicaux dont la production est l’apanage des seuls armateurs étrangers. À partir des documents de référence et des données de terrain, la présente contribution se donne l’ambition d’analyser l’organisation de la filière thonière dans son ensemble, d’identifier les dérives qui s’en suivent, mais aussi, de penser les mécanismes favorables à la mise en place d’une industrie du thon au Gabon.
Le patrimoine comme levier de développement territorial. Cas des ressources patrimoniales du parc national de Tlemcen (Algérie)

Published: November 2021

En Algérie, la protection et la mise en valeur du patrimoine est l’une des orientations stratégiques du Schéma National d’Aménagement du Territoire à l’horizon 2030. À cette fin, les Pôles d’Économie du Patrimoine et les Parcs Culturels sont introduits comme une nouvelle alternative de développement territorial articulé autour d’un concept nouveau : « le projet de territoire ». Or, la mise en œuvre de ce projet dépend non seulement de facteurs physiques spécifiques au patrimoine en question mais surtout de l’implication effective de toutes les parties prenantes. Les acteurs locaux qui sont confrontés au quotidien, aux besoins de leurs territoires sont souvent exclus d’un processus de décision caractérisé par une forte centralisation. Par conséquent, l’objectif du présent article consiste à élaborer et tester un outil d’évaluation de la capacité de contribution des ressources patrimoniales au développement durable territorial. Le résultat attendu est de proposer une démarche de mise en valeur des projets patrimoniaux basée sur un diagnostic des différentes potentialités et contraintes et sur l’ouverture du processus de prise de décision aux acteurs locaux et aux habitants. Le parc national de Tlemcen dans la région Ouest de l’Algérie a été sélectionné comme cas d’étude au vu de la richesse de son patrimoine paysager et culturel et de par l’échelle intercommunale qu’il couvre.
A Study of Hegemony and Class Conflict in Gaskel’s North And South
Authors: Al-Khafaf Ziead
Published: November 2021

The paper discusses the relation between the north and south as two different geographical locations in the novel. By focusing on them, the article focuses on the hegemonic role of the classes and the emerging conflict. The conflict seems to be fought on industrial grounds but it relates to an intellectual and political awareness that plays a vital role in the sustenance of the ideological changes that take birth. The grave relationship of both classes is not controlled by sheer force but by a well thought out plan that plays a vital role delaying the emergence of a revolution in the working class. The void between the classes is sustained by a powerful mechanism which is indirectly ruling the entire arena of factories their workers and unions. Ironically the unions that are supposed to secure the lives and rights of the working class fall prey to the power of the industrialist.

Developing a catalyst for green hydrogen production through water splitting, is one of the most promising ways to meet current energy demand. Here, we demonstrate spontaneous water splitting using gadolinium telluride (GdTe) with high hydrogen evolution rate. The spent catalyst can be reused after melting, which regains the original activity of the pristine sample. The phase formation and reusability are supported by the thermodynamics calculations. The theoretical calculation reveals ultra-low over-potential for hydrogen evolution reaction of GdTe caused by charge transfer from Te to Gd, hence enhancing the catalytic activity. Production of highly pure and instantaneous hydrogen by GdTe could accelerate fuel cell-based sustainable technologies.

Published: November 2021

Aim. To investigate the effect of allelic polymorphisms of the MMP2 gene on uterine perfusion in patients planning pregnancy.
Materials and methods. 95 women planning pregnancy were examined. The patients underwent clinical and laboratory examination, analysis of single nucleotide polymorphisms rs2285052 and rs243865 of the MMP2 gene, ultrasound examination on days 1825 of the menstrual cycle with an assessment of the pulsatility index of blood flow of the uterine vessels and a qualitative assessment of endometrial and subendometrial perfusion. Depending on the genotype, the patients were divided into 3 groups: first with haplotype rs2285052(A)rs243865(T), second with haplotype rs2285052(A)rs243865(С), and a third control group with rs2285052(С/С)rs243865(С/С) genotype.
Results. Decreased perfusion in the subendometrial zone was found in 40.6, 44.4 and 19.4% of patients in the 1, 2 and 3 groups, respectively; decreased perfusion of endometrium in 68.8, 55.6 and 36.1% of patients in the 1, 2 and 3 groups, respectively. Spiral arteries were not visualized in 28.1, 14.8 and 11.1% of patients in the 1, 2 and 3 groups, respectively. No statistical differences were found in the pulsatility index of uterine blood flow depending on the genotype.
Conclusion. In patients with the A rs2285052 and T rs243865 alleles of the MMP2 gene poor vascular patterns of the endometrium and subendometrial zone of the uterus were statistically significantly more frequent, which can lead to infertility. These associations are more pronounced for the rs2285052 polymorphism. The simultaneous determination of the rs2285052 and rs243865 polymorphisms does not provide additional information compared to the definition of rs2285052 alone.

Published: November 2021

Food is an effective way for rural communities to introduce their culture. Therefore, they
make various mobilization efforts to popularize their traditional foods. It comes as no
surprise that the traditional ceremonies are held as a means of branding to promote these
localities. This study was aimed to describe the local traditional foods presented at the
Kebo-keboan traditional ceremony in Alasmalang, Banyuwangi district, Indonesia as a
reflection of the culture within the Alasmalang community. The analysis focused on the
philosophy of traditional foods to unravel the culture within the Alasmalang community.
The data were collected through in-depth interviews to receive profound information. The
data analysis was done using interactive methods. There were six variations of local foods
found in the Kebo-keboan traditional ceremony, namely Pecel Pitik, Tumpeng Putih,
Tumpeng Kuning, Jenang Abang, Jenang Suro, and boiled produce. All the local foods are
made from local ingredients with local cultural beliefs lying within them. These foods
reflect the religious, social, and environmental-loving culture of the Alasmalang
community as well as a means of promoting local culture. The findings can serve as
initiatives for cultural promotion elsewhere as well as an expansion in cultural studies

The medical data of 155 patients who received a non-penetrating gun-shoot head injuries during the war in the Eastern Ukraine between 2014‒2020 were analyzed. All patients were males between 18 and 60 years (average age ‒ 35.1 years). The peculiarities of clinical manifestations and results of diagnostic evaluation of non-penetrating gun-shoot head injuries during specialized neurosurgical care in medical institutions on the third and fourth levels of medical aid have been studied.Results. Wide diagnostic capabilities of MSCT were revealed for determination of the wounds localization, type of the projectile, the nature of the wound channel, gunshot skull fractures, and associated intracranial injuries. It was found that with non-penetrating bullet and shrapnel tangential cranio-cerebral wounds, incomplete and depressed fractures usually occurred, and with single and multiple shrapnel blind wounds, incomplete ‒ perforated and depressed fractures with the presence of bone fragments. The pathomorphological features of the nature of the wound channels and intracranial injuries were determined. They are always associated by traumatic subarachnoid hemorrhages and brain contusions, in most cases – focal. Intracranial hematomas were observed in 3.1 % of the patients.Conclusions. Clinical manifestations of the non-penetrating craniocerebral gunshot wounds depend not only on the type of cranial soft tissue injury, but also on the nature of the skull fracture and are mainly occurred because of the severity of the traumatic brain injury. MSCT of the head makes it possible to determine the localization of the wound, the type of the wounding projectile, the nature of the cranial soft tissues damage, wound channel, gunshot skull fractures and associated intracranial injuries.

A lot of recommendations has been published regarding the treatment of chronic venous disease. At the same time, none of these documents reflects the complete «path» of the patient from the stage of the initial visit (diagnosis) to the choice of the optimal treatment option. Therefore, the creation of a protocol that would take into account on the one hand the most modern and proven effective approaches to diagnosis and treatment, and on the other hand, the individual characteristics of each clinical case is an urgent task.The main task of the publication is to create a practice-oriented instruction for the diagnosis, comprehensive treatment and prevention of chronic venous insufficiency. The management of a patient with chronic venous insufficiency is presented in the form of «AngioLife Venous Protocol®», a set of clear practical recommendations for vascular surgeon and phlebologist. This protocol is based on our own practical experience, existing protocols and guidelines for the treatment of patients with chronic venous insufficiency. The venous protocol includes four stages of a set of medical measures, the purpose of which is to form a clear program of further examination and treatment of the patient. Adherence to all the recommendations specified in the protocol allows to obtain satisfactory functional and cosmetic results of treatment of patients with chronic venous insufficiency with minimal risk of recurrence.

The observation of endovascular treatment of acute tandem occlusion of internal carotid artery (ICA), anterior cerebral artery (ACA) and middle cerebral artery (MCA) in combination with the thrombosis of the right ICA and the critical stenosis of the left vertebral artery is presented.Man, 61 years old. He was delivered to the Center of endovascular neuroradiology, NAMS of Ukraine on January 15, 2021 with an ischemic stroke clinic in the left internal carotid artery basin. He fell ill acutely ‒ against the background of complete well-being, sensorimotor aphasia and right-sided hemiplegia appeared. Upon admission on the NIHSS (National Institutes of Health Stroke Scale) ‒ 18 points. On the performed initial multispiral computed tomography of the brain according to ASPECTS (Alberta Stroke Program Early CT score) ‒ 8 points. In the endovascular operating room, cerebral angiography was performed, followed by surgery aimed at restoring cerebral blood flow. The time from the onset of the disease to the puncture was 330 minutes, the duration of the operation was 135 minutes, thus the time from the onset of the disease to reperfusion was 465 minutes. Angiography revealed acute thrombosis of the left ICA starting from the orifice, M1-segment of the left MCA and A2-segment of the left ACA. Partial compensation of the basin through the supra-block anastomosis (external carotid artery ‒ ICA), as well as from the vertebro-basilar system through the network of leptomeningeal arteries. Collaterals ‒ ACG 3. Thrombosis of the right ICA and critical stenosis (95 %) of the V1-segment of the left vertebral artery were also revealed. The operation was performed ‒ recanalization of thrombosis of the left ICA orifice followed by balloon angioplasty, thrombectomy from the MCA and ACA pools. The end result is eTICI 2c reperfusion. There were no complications during this operation. The patient was discharged the next day (transferred to the neurological department at the place of residence). Control multispiral computed tomography of the brain showed positive dynamics (ASPECTS ‒ 1 point).
Determining the Optimal Sleep Pattern to Promote Glymphatic Clearance of Amyloid-Beta in Individuals at Risk for Alzheimer's Disease: A Research Protocol
Authors: Bansal Muskan , Musa Shahad , Mulpuru Manitha
Published: November 2021

Introduction: Neurodegenerative disorders such as Alzheimer’s disease (AD) are increasingly prevalent amongst older populations. Sleep irregularities are one of the chief complaints in people diagnosed with sleep disorders. Sleep has been hypothesized to ensure metabolic homeostasis and remove neurotoxic waste. Inadequate sleep leads to an accumulation of Amyloid-Beta (Aβ) levels which is associated with neurodegenerative diseases including AD and other dementias. Sleep is the driver of the glymphatic system, located in the perivascular space. The glymphatic system eliminates soluble proteins, including Aβ, from the central nervous system; transporting cerebrospinal fluid through the brain; and distributing macromolecules across the brain. This research proposal aims to identify optimal sleep patterns that decrease neurodegeneration by increasing glymphatic system functioning.
Methods: This study will be an ad-hoc study conducted over a 6-month period utilizing participants who have reported a family history of AD. Aß accumulation and cortisol levels will be measured to identify signs of neurodegeneration using brain scans, such as Positron Emission Tomography, and blood tests. Other parameters such as memory, energy rating, and sleep latency will be measured.
Results: Reduced slow-wave sleep may lead to a disruption in the glymphatic system. Monophasic sleep is said to have the most slow-wave sleep, and least rapid eye movement sleep which is most similar to wakefulness. Therefore, we hypothesize that monophasic sleep will slow neurodegeneration compared to biphasic and polyphasic sleep, contrary to popular belief that biphasic sleep is more beneficial than monophasic sleep.
Discussion: In this experiment, we expect to see increased glymphatic clearance after monophasic sleep. There are many factors that can impact sleep patterns and glymphatic clearance including work style, environment, culture, race, sex, and genetic markers for AD.
Conclusion: Further research that applies this suggested methodology should account for these variabilities when making conclusions on the optimal sleep pattern for plaque clearance in the brain. This proposal may improve research on AD by identifying the effects different sleep patterns have on the brain and neurodegeneration. Future research may study changes in sleep habits as a preventative measure for individuals who are at risk for or have been diagnosed with AD.
Behavioural Consequences of Consumer Ethnic Identification and Acculturation: An Investigation in the Context of Targeted Online Advertisements
Authors:   , Allan Michael
Published: November 2021

Previous studies indicate that consumers generally prefer advertisements that feature ethnically similar models. However, most of these studies are conducted using Hispanic or Black consumer samples in the context of outdated targeted marketing practices. Basing the theoretical foundation on Self-Identification Theory, the Theory of Planned Behaviour, and Distinctiveness Theory, this paper uses quantitative data collecting and data analysis techniques to explore various aspects of the effects of consumer ethnic identification and acculturation on product purchase intention in the context of Asian identifying consumers in New Zealand. This thesis further explored the impact of attitude toward targeted advertisements in the context of ethnic targeting towards Asian identifying consumers. The findings of this study suggest that the use of Asian models in ads may enhance purchase intention of advertised products among consumers who strongly identify as ethnically Asian, as well as among Asian identifying consumers who have not acculturated strongly to New Zealand culture. This study further found that, where consumers are aware of being personally targeted based on demographic information, consumer purchase intention regarding advertised products may be significantly positively influenced by their attitude towards the practice of targeted advertising itself. These results carry several implications, both practical and theoretical. Specifically, these results may suggest that marketing managers in countries with large (though still in the minority) Asian consumer populations may benefit greatly from engaging in targeted ethnic advertising towards this demographic. Furthermore, the integration of the three theories used into a novel conceptual model represents a potential use in future similar studies.

Landslide is one of the natural disasters which cause not only infrastructure damage but also death. Nurses have a role in disaster management at the phase of mitigation to rehabilitation during landslide disasters.  This study is aimed to analyze nurses' knowledge and attitudes in the face of future landslide disasters. A quantitative method with a descriptive design was used in the study. The respondents in this study were 20 nurses who work at one rural community health center in Malang. Data were collected using a questionnaire. From the current research, most respondents had been involved in disaster emergency response activities (85%), had good knowledge (75%), and all nurses (100%) had a positive attitude towards landslide disaster preparedness. From this current study, nurses' knowledge and attitudes towards preparedness for facing landslides might be essential to build more awareness among nurses in preparing the community in facing landslides; thus, the impact of the disaster could be decreased.
