Authors: C B Brindashree
Published: July 2021

At present in our education system, students tend to study in different cities or states according to their choices or situations. Thus a lot of students tend to have meals at college canteens due to one or the other reason. The breaks for such meals are very short and the students rush for the canteens of their colleges. Due to sudden increase of footfall in the canteen only a few of the students get their orders served in time while the rest are busy waiting throughout their break. Being unaware of the food (menu) orders, canteen staff are helpless at that time of footfall. To overcome this issue due to manual ways of handling orders, canteen automation system is the key solution. Payment gateway is one added feature to make the process cashless and easy.

Published: July 2021

Dental caries is an infectious disease of teeth which end up in the destruction of dental hard tissue. Poor oral hygiene is one of the major factor for accumulation of microorganisms and their harmful effects. The current study was done on antimicrobial efficacy of different brands of toothpastes against organisms isolated from patients having dental caries and comparative analysis has been made between chemical and herbal based toothpastes. Primary screening of organisms had been carried out on sterile Nutrient Agar medium and five isolates (A1, A2, A3, A4 and A5) were obtained. Antimicrobial activity of toothpastes was checked using Agar well diffusion assay. In chemical based toothpastes, Close-up showed the maximum zone of inhibition of 30mm against A1 isolate and minimum efficacy was observed with Pepsodent with zone of 7mm against A4 isolate. In herbal based toothpastes, Babool showed highest effectiveness with zone of 28mm against A3 isolate and minimum with zone of 10 mm with Dabur red and Himalaya against A1 and A3 isolate. The comparative analysis showed that chemical based toothpastes are more effective than herbal based toothpastes. Further studies on probiotic approach should be done which has been a popular method used to affect oral microbial community.
Single Board Computer Applications as Multi-Server VoIP
Authors: Atmadja Martono Dwi
Published: July 2021

Telecommunication technology is developing along with information technology and several innovations in several audio and data transmission and reception techniques. Innovation and communication technology are hoped to be able to create efficiencies in regards to time, equipment, and cost. The Public Switched Telephone Network (PSTN) telephone technology has experienced integration towards communication using Internet Protocol (IP) networks, better known as Voice over Internet Protocol (VoIP). VoIP Technology transmits conversations digitally through IP-based networks, such as internet networks, Wide Area Networks (WAN), and Local Area Networks (LAN). However, the VoIP cannot fully replace PSTN due to several weaknesses, such as delay, jitter, packet loss, as well as security and echo. Telephones calls using VoIP technology are executed using terminals in the form of computer devices or existing analogue telephones. The benefit of VoIP is that it can be set in all ethernet and IP addresses. Prefixes can be applied for inter-server placements as inter-building telephone networks without the addition of inefficient new cables on single board computers with Elastix installed. Prefix and non-prefix analysis on servers from single board computers can be tested using QoS for bandwidth, jitter, and packet loss codec. The installation of 6 clients, or 3 simultaneous calls resulted in a packet loss value in the prefix Speex codex of 2.34%. The bandwidth in the prefix PCMU codec has an average value of 82.3Kbps, and a non-prefix value of 79.3Kbps, in accordance to the codec standards in the VoIP. The lowest jitter was found in the non-prefix PCMU codec with an average of 51.05ms, with the highest jitter for the prefix Speex codec being 314.65ms.

Published: July 2021

In today’s globalized world, highway is the means to join countries, cities, towns etc. In recent years all the old technologies changed into new technology. All the things are changed but highways are not changed. The "Smart Highway with glowing lines" is the concept to make highway roads smarter, safer, and more energy efficient for generating energy using solar energy. In the part of Smart Highways with Glowing Lines the road glow in the dark lines is installed, called Glowing Lines. These lines collect energy during the day and give light in the evening. Here the landscape becomes an experience of light and information. As a result, this increases visibility and safety. Smart highways and smart roads are terms for a number of different proposals to incorporate technologies into roads like Smart Road with Glowing Lines, for lighting road at Night Time. This innovative concept creates an entirely new mobility experience for drivers, cyclists and pedestrians. Ideas from this testing ground are increasingly becoming part of our everyday landscape. Intelligent transportation systems usually refer to the use of information and communication technologies in the fields of road transport, including infrastructure, vehicles, users, traffic management and mobility management as well as interfaces with other modes of transport. This clearly shows that mobility can be smarter, more interactive and more sustainable without having to widen roads or lay more rail connections. It is simply a case of putting demand first.

Authors: Uthappa Vidhu
Published: July 2021

The increase in the number of vehicles increases the number of accidents. India ranks first in the world by 11% where a greater number of accidents occur followed by China and the USA. Most road accidents occur due to human errors. The Advanced Driver Assistant System is developed to Automate, Adapt and increase the safety of the vehicle and driver and also to ensure better driving. The safety features in this system are designed and developed to avoid collision by using technologies that give an indication or alert to the driver regarding problems, implementing safe grounds, and controlling the vehicle if necessary. In recent years Ultrasonic sensor-based systems and the rear-view camera-based system is been used by different car manufacturers which are available only on higher-end vehicles. In the proposed system we calculate the frontal road width by capturing an image using a Vehicle Frontal Camera(VFC) and processing it for proper judgment of space available for the vehicle to pass, with that surround space detection is achieved by using LIDAR and detection of unattended pets/child inside the vehicle by using IR proximity sensors and identification of pets/objects under the vehicle using Chassis level camera when parked in a remote location or cities to avoid loss of life of animals and to avoid the damage caused to the vehicle.

Authors: K Deepthi
Published: July 2021

Animals watching is a common hobby but to identify their species requires the assistance of Animal books. To provide Animal watchers a handy tool to admire the beauty of Animals, we developed a deep learning platform to assist users in recognizing species of Animals endemic to using app named the Imagenet of Animals (IoA). Animal images were learned by a convolutional neural network (CNN) to localize prominent features in the images. First, we established and generated a bounded region of interest to the shapes and colors of the object granularities and subsequently balanced the distribution of Animals species. Then, a skip connection method was used to linearly combine the outputs of the previous and current layers to improve feature extraction. Finally, we applied the SoftMax function to obtain a probability distribution of Animals features. The learned parameters of Animals features were used to identify pictures uploaded by mobile users. The proposed CNN model with skip connections achieved higher accuracy of 99.00 % compared with the 93.98% from a CNN and 89.00% from the SVM for the training images. As for the test dataset, the average sensitivity, specificity, and accuracy were 93.79%, 96.11%, and 95.37%, respectively.
Augmented Reality for Implementation of Virtual Watch
Authors: M D Abhay Kumar
Published: July 2021

Augmented reality is an interactive experience of a real-world environment where the objects or images that reside within the world are enhanced or supplemented by computer-generated perceptual information. Augmented Reality adds a thing to the existing world. It is an enhancement to the real world where we mix the real world with the virtual objects. In this paper, we are proposing a methodology that builds a preview of the virtual watch object alongside the real environment. Using this methodology users can place the virtual watch on their wrist and visualize it in their personal space. This eventually reduces the challenging task of walking into a showroom and trying different watches, as the user gets a clear preview before purchasing the actual item. This methodology is best suited for this technology-driven environment.

Published: July 2021

The paper analyzes content and spatial distribution peculiarities of macro- and microelements in the bottom sediments of Sevastopol bays, Feodosiya Gulf and Kerch Strait. Bottom sediment sampling was performed from 2005 to 2008 as well as in 2015, 2016, and 2018. Concentrations of macro- (Ti, Fe, Mn) and microelements (As, Pb, Zn, Cu, Ni, Co, Cr, V, Sr) were studied by X-ray fluorescence analysis using Spectroscan MAKS-G spectrometer. The maximal content of Cr, Co, Ni, Zn, Pb, Sr exceeding the geochemical background was found in the water areas with difficult water exchange, which include bays of the Sevastopol region under intense anthropogenic influence: the Yuzhnaya Bay, Gollandiya Bay and Kilen-Bay. In the Kazachya Bay, the least polluted in the Sevastopol bay system, the content of Cr, Co, Ni, Zn, Pb, As, Sr also exceeded their geochemical background. As illustrated by the Balaklava Bay, the paper shows the influence of local pollution sources (the Balaklavka River runoff and municipal waste water) on the microelement distribution. Sevastopol bays are characterized by high concentrations of the studied elements in the bottom sediments. In the water areas with active water exchange, i. e. Feodosiya Gulf and Kerch Strait, concentration of the studied elements, except for Ni, Zn and Cr, did not exceed on the average the geochemical background of the open Black Sea shelf areas.

Published: July 2021

Based on point classifications, methods for geoecological zoning of water areas during dredging have been developed. Fourteen factors and quantitative indicators of their assessment are proposed characterizing the degree of negative influence of dredging on the ecological state of water areas. An expert assessment of the influencing factors significance was carried out. The weighting coefficients of the factors were calculated by the ranking method. Geoecological zoning of the seaport of Arkhangelsk water area in the Northern Dvina mouth area was carried out during dredging operations by means of a point-rating assessment of the water area. The areas most susceptible to the negative effect of dredging are those with the largest observed volumes of annual sediment accumulation (sea canals in the estuarine seashore zone (Mudyug canal)) and those with the highest level of pollution of waters and bottom soils (water areas with active harbour and other technogenic activities (Bakaritsa)). Delta areas, in particular the Maimaksan channel, have the most favorable conditions for dredging with the least possible negative impact on the ecological situation. With regard to the mentioned objects, a verbal-numerical scale of geoecological assessment has been compiled. The method can be recommended for use in all tidal estuaries of rivers in the Arctic seas.

The aim of this work is to study the dynamics of bottom sediments granulometric fractions in the Kalamitsky Gulf coastal zone near the Lake Sakskoe bay-bar under influence of storm surge based on the XBeach numerical morphodynamic model. A series of numerical experiments has been carried out, in which the parameters of waves at the seaward boundary of the computational domain changed in time, simulating the passage of a cyclonic atmospheric anomaly over the investigated region. The initial distribution of the sediment volume concentrations in different parts of the underwater coastal slope profile was set based on the results of field observations. The duration of model calculations was 24 h. The quantitative characteristics of the spatial distribution of various bottom sediments fractions, sediments median diameter and values of bottom deformations were obtained. It has been established that the main morphodynamic changes occurs in the area 0–120 m from the shoreline and are limited by the 3.5 m isobath. It was noted that the maximum changes in the relief of the coastal zone and the upper section of the underwater coastal slope occur during the development and attenuation phases of a storm. In the same time intervals an intensive redistribution of sandy material is observed. It has been established that, with a change in the parameters of wind waves in time at the seaward boundary, the scales of sand material redistribution and deformations of the coastal zone are higher than in the experiment when the direction of the waves does not change with time at the seaward boundary of the computational domain.

The article studies the influence of wind forcing associated with the Arctic Oscillation on the water circulation regimes in the sector of the World Ocean (65–81.5 N, 0–70 E), which consolidates the North, Norwegian and Barents Seas. The study aims at establishing quantitative patterns of variability of the ocean level and surface geostrophic current velocities depending on the value of the Arctic Oscillation index. In general, the response of the sea level averaged over the ocean sector under consideration is in an antiphase with this index. However, there are periods of mismatch between antiphase fluctuations of the sea level and the Arctic Oscillation index. After 2009, an increase in the amplitude and a decrease in the duration of the phases of the Arctic Oscillation index are noted. The difference between the areas of positive and negative values of sea level anomalies creates a pressure gradient that causes surface geostrophic currents carrying Atlantic waters along the shelf edge eastward in a cyclonic regime (the Arctic Oscillation index is greater than 0) and westward in an anticyclonic regime (the index is less than 0). The article provides estimates of the linear regression coefficients: for the sea level they are ~ 2 cm in the shelf zone and about minus 1 cm in the deep-water part of the sector. Thus, the level difference between the shelf and the deeper part of the considered water area is ~ 3 cm per 1 unit of the Arctic Oscillation index. Estimates of the linear regression coefficients for anomalies of the geostrophic currents velocity were ~ 0.5 cm/s per 1 unit of the index. Analysis of the longterm variability of the steric component of the ocean level showed a better relationship with the interannual variability of the Arctic Oscillation index as compared to the ocean level.

Anthropogenic impact on lithodynamics of the coastal zone changes the natural dynamics of bottom sediments, which leads to increased abrasion and swelling of beaches, activation of landslide processes creating a threat of destruction of the coastal infrastructure. The article aims at providing an overview of the scientific literature on the anthropogenic impact on lithodynamics of the coastal zone of the southern and western coasts of the Black Sea (shores of Romania, Bulgaria and Turkey). The work shows that with all the differences in the natural conditions of the coastal zones of these countries the types of anthropogenic effects they undergo are almost the same. These include: hydrotechnical construction without regard to the impact on the neighbouring coast sections; reduction of solid river flow due to river regulation by reservoirs; construction of capital facilities directly on the beaches; illegal extraction of sand from beaches and river beds; dredging with sale of the extracted material to construction companies; covering of cliffs by various structures; destruction of coastal dunes, etc. The main negative consequences of these actions are reflected in disruption of natural dynamics and shortages of bottom sediments, changes in the coastline, reduced aesthetic attractiveness and accessibility of shores, destruction of coastal ecosystems. The article also provides information on the legislation of these countries regarding environmental management in the coastal zone

The article studies interrelations of the beam attenuation coefficient in different spectrum regions and spectral relations of beam attenuation coefficient to the Secchi depth in the coastal waters of the South Coast of Crimea. The data were used of in situ optical measurements obtained in 2008–2014 from a stationary oceanographic platform installed in the coastal waters of the South Coast of Crimea near the village of Katsiveli. According to the measurement data the relation was determined of the beam attenuation coefficient in eight parts of the spectrum in the wavelength range of 416–640 nm to the Secchi depth, which varies from 6 m to 17.5 m. Spectral distributions of the beam attenuation coefficient at different Secchi depths in coastal and deep sea waters were compared. As a result, it is concluded that the relationships between the spectral attenuation coefficient and the Secchi depth in coastal waters are not applicable to deep sea waters. It is shown that the feature of such equations in coastal waters is related to the higher concentration of fine suspended matter in them. Intercorrelation parameters were calculated of beam attenuation coefficients in different spectrum regions in coastal waters. High correlation coefficients make it possible to reconstruct distribution of the attenuation coefficient in a wide spectral range based on measurements at one wavelength in any spectrum region. The optimal spectral region to measure the beam attenuation coefficient is 468–527 nm.

The paper investigates the seasonal variability of the vertical turbulent exchange coefficient in the upper stratified layer of the Black Sea. The expedition data used in this work containing information on the microstructure of physical fields were obtained in different hydrological seasons covering the northeastern part of the Black Sea in the Prikerchensky area of the shelf slope. The data were collected during cruises of r/v “Professor Vodyanitsky” in 2016–2019 using “Sigma-1” sounding complex. Based on the semi-empirical methods of assessment of vertical turbulent exchange in the deep-water area of the Black Sea, the dependence of the vertical turbulent diffusion coefficient K on the buoyancy frequency N in the studied layer was established from the flow fluctuation characteristics, with the corresponding graphs and their approximating power-law dependences K  A  N  plotting. In addition, the vertical distribution of the K coefficient with depth was analyzed. Comparative analysis of the obtained dependences with the results of the 1.5D model was carried out. The analysis of the measurement data showed that the results obtained in this work do not contradict the original model. The results can also be used to assess the vertical fluxes of heat, salt and other dissolved chemical and biological substances depending on stratification in the studied part of the Black Sea for different seasons.

A patient with late in COVID-19 pneumonia presented peripheral cystic
features on chest computed tomography, which were spontaneously resolved
with no antibiotic therapy or surgery. Physicians should pay attention
to follow up the late phase of COVID-19 pneumonia for better
understanding its etiologies and clinical course in the convalescing
period.

Multisystem inflammatory syndrome in children (MIS-C) associated with
coronavirus disease 2019 (COVID-19) has been described to partially
overlap with Kawasaki disease (KD) with regard to clinical symptoms, but
they are unlikely to share the same disease entity. We conducted a
systematic review and meta-analysis to characterize the laboratory
parameters of MIS-C compared with those of KD and Kawasaki disease shock
syndrome (KDSS). Databases were searched for studies on laboratory
parameters of MIS-C (hematology, inflammatory markers, cardiac markers
and biochemistry) through May 31, 2021. Twelve studies with 3073
participants yielded 969 MIS-C patients. In terms of hematology, MIS-C
patients had lower levels of leukocytes, absolute lymphocyte count and
platelet count (PLT) than KD patients and had similar absolute
neutrophil count (ANC) and hemoglobin (Hb) levels. In terms of
inflammatory markers, MIS-C patients had higher levels of C-reactive
protein, D-dimer and ferritin than KD patients and had similar levels of
procalcitonin and ESR. In terms of cardiac markers, MIS-C patients had
higher CPK levels than KD patients. The levels of NT-proBNP, troponin
and AST were not significantly different between MIS-C and KD patients.
In terms of biochemistry, MIS-C patients had lower levels of albumin,
sodium and ALT and higher levels of creatinine than KD patients. In
addition, MIS-C patients had lower levels of PLT, Hb and ESR and higher
levels of ANC than KDSS patients. Measurement of laboratory parameters
might assist clinicians with accurate evaluation of MIS-C and further
mechanistic research.

In this paper, we prove that the following planar Schrödinger-Poisson
system with zero mass -Δu+φu=f(u), x∈R^2, Δφ= 2πu^2, x∈R^2,
admits a nontrivial radially symmetric solution under weaker assumptions
on f by using some new analytical approaches.

The morphology variations of the so-called scimitar vein are many and
varied. We present a synthesis of 92 published investigations of the
overall scimitar syndrome. We reviewed the clinical presentations,
diagnostic modalities, surgical approaches, and outcomes. Diagnostic
information was provided by clinical presentations, radiographic
findings, transthoracic and transesophageal echocardiography,
computed-tomographic angiography, magnetic resonance imaging,
angiocardiography, and ventilation/perfusion scans. These investigations
served to elucidate the origin, course, and termination of the scimitar
vein, the intracardiac anatomy, the presence of associated defects, and
the patterns of any accompanying pulmonary lesions. In short, they
defined the disease prior to surgical intervention. Of the patients
described, up to four-fifths presented during infancy, with cardiac
failure, increased pulmonary flow, and pulmonary hypertension.
Associated cardiac and extracardiac defects, particularly hypoplasia of
the right lung, are present in up to three-quarters of cases. Overall
operative mortality has been cited between 4.8% and 5.9%. Mortality
was highest in patients with preoperative pulmonary hypertension, and
those undergoing surgery in infancy. Despite timely surgical
intervention, post-repair obstruction of the scimitar vein, intra-atrial
baffle obstruction, or stenosis of the inferior caval vein were reported
in up to two-thirds of cases. The venous obstruction could not be
related to any particular surgical technique. On long term follow-up,
one sixth of patients reported persistent dyspnoea and recurrent
respiratory infections. Any infants presenting with heart failure,
right-sided heart, and hypoplastic right lung should be evaluated to
exclude the syndrome. An increased appreciation of variables will
contribute to improved surgical management.

A Realist Review of the Home care Literature and its Blind Spots
Authors: Contandriopoulos Damien , Stajduhar Kelli , Sanders Tanya , Carrier Annie , Bitschy Ami , Funk Laura
Published: July 2021

Rationale, aims and objectives: There is a large body of literature from
all over the world that describes, analyzes, or evaluates home care
models and interventions. The present article aims to identify the
practical lessons that can be gained from a systematic examination of
that literature. Method: We conducted a three-step sequential search
process from which 113 documents were selected. That corpus was then
narratively analyzed according to a realist review approach. Results: A
first level of observation is that there are multiple blind spots in the
existing literature on home care. The definition and delimitation of
what constitutes home care services is generally under-discussed. In the
same way, the composition of the basket of care provided and its fit
with the need of recipients is under-addressed. Finally, the literature
relies heavily on RCTs whose practical contribution to decisions or
policy is disputable.At a second level, our analysis suggests that three
mechanisms (system integration, case management and relational
continuity) are core characteristics of home care models effectiveness.
Conclusion: We conclude by providing advice for creating effective home
care system change through rational and participatory design and
evaluation alongside public dialogue about the purpose and future of
home care.

Paraparetic Guillian-Barre Syndrome is an uncommon variant of GBS. We
describe a case of a teenage boy, who developed progressive, symmetric
weakness of the lower limbs following an upper respiratory tract
infection. Post-infectious, monophasic, acute, symmetric course were
suggestive of paraparetic GBS which were further confirmed by CSF,
electrophysiologic fndings.

Objective: To review the effect of the COVID-19 pandemic on the
presentation of Cervical cancer. Design/ Setting: Retrospective study
involving the Regional Cancer Centres in the M62 Group. Methods: Data
was collected for two equal time periods. All cervical cancers were
included and FIGO 2018 staging was used for the data collection. P
values were calculated using binomial hypothesis test for the difference
in staging. Time from symptoms to diagnosis was assessed using a normal
distribution test. All other calculations were performed using
chi-squared test. Statistical significance was considered if p values
were <0.05. Main outcome measures: Histology, stage at
diagnosis, date of onset of symptoms, investigation and type of
treatment. Results: A total of 406 cases of cervical cancer were
reviewed; 233 from May – October 2019 (pre-COVID) and 173 between May
– October 2020 (post COVID); representing a significant reduction in
new cervical cancer diagnoses of 25% post COVID (p<0.001)
There was a 42% increase in the delay from start of symptoms to
diagnosis Post COVID. Pre COVID, 27% of patients presented with Stage 3
or 4 disease, whilst during COVID this was 38%; statistically
significant (p <0.001). When we evaluated the treatments
received between the two time periods, this was also statistically
significant (chi-squared, p=0.0005). Conclusions: This study has
demonstrated a statistically significant increase in the stage of
cervical cancer at diagnosis and a change in treatment for cervical
cancer following the onset of COVID-19. The implications of this are
discussed.
