Published: July 2021

The major threat to the environment is the disposal of waste plastic and on the other side; the road traffic intensity is increasing. The load bearing capacity of roads are increasing. This study discusses the suitability of plastic waste for construction of roads. A material that contain more organic polymer of large molecular weight, solid in its finished state, can be shaped by its flow is called as “plastic”. Generally plastic is used in various domestic and industrial applications. In the Current Period Use of plastic bags and bottles is very common. Use of plastics in road construction can reduce the cost of road construction and pollution index of environment to an appreciable extent. Use of this mix for road construction it helps to reduce or use plastic waste effectively. Use of waste plastic in construction material is becoming more and more acceptable due to the improved properties. Due to use of waste plastic the Cost of construction materials also decreases. When we use the waste plastic in flexible pavement it improves the abrasion & slip resistance of asphalt pavement. It is economical and eco-friendly.

Authors: Katarpawar Raghvendra
Published: July 2021

Sustainability is a widely acknowledged concept in modern day construction scenario. Although the construction industry is transforming in a substantial way in terms of the material used and the equipment used, the construction cost has risen steeply along with the worse impact on the environment due to this it has resulted in the acceptance of method like the use of natural fiber for example Coconut fibre for improving the strength of concrete. Coconut fiber is easily and widely available in abundance, which makes it fairly sustainable as form of reinforcement material in concrete. The use of coconut fibre as in form of reinforcement has also emerged as new source of income for the coconut producer. In addition, it can also be seen as a new effective way for the discarding of coir mattress wastage. The major problem of coconut fibre i.e. high water absorption rate of the fibre can be reduced to certain extent by coating the fibres with appropriate oil. In addition to this, the fibres which are naturally occurring is also ecologically sustainable and can lower the global carbon track effectively. This study aims to analyse the difference in strength of coconut fibre (processed fibres coated with oil and oil raw fibres coated with oil) reinforced concrete at various fibre contents and to collate it with the traditional concrete. The different strength aspects which are analysed in this study are the tensile, compressive and flexural strength of the concrete reinforced with coconut fibre at different percentages like 4%, 5% & 6% by the weight of cement of fibre. The optimum percentage of the raw fibre meshes and processed fibre were found and the optimum percentage of super-plasticizer required for the desired workability was also examined.

Assessing the Damage Mechanism in Reinforced Concrete Beams under Repetitive Low Velocity Impact Loading
Authors: K Sajina
Published: July 2021

Reinforced concrete beams are widely used in various civil structures such as residential, industrial, and commercial buildings. The use of RC beams reduces the cost of the construction and the time of execution. Rockfalls, accidental events, explosions, projectile, missile or aircraft impacts, terrorist attacks and ice impacts are the typical examples of sudden loads. Experimental studies can be impractical and require expensive devices to observe crack pattern and failure due to impact loading. Similar results can be obtained through non-linear finite elements analysis. In this study, RC beam is modelled and analyzed for changing impact velocity. Beam properties like clear cover is varied to access the damage in beams.

Published: July 2021

Introduction. The relevance of the topic, addressed in the article, is backed by the fact that modern heating systems, such as the underfloor heating, remain potential sources of fire, despite the improvement in their designs. The purpose of the study is to identify the causes of fires that occur in the process of operation of modern heating systems “Underfloor Heating”; to analyze and generalize the conclusions made by the fire safety experts in respect of the heating systems analyzed in the article.Materials and methods. To assess the flammability of the infrared film underfloor heating, an experiment was conducted by the experts: the process of underfloor heating was simulated under normal environmental conditions at room temperature.Results and discussion. The experiment has shown that the floor covering, made of the material capable of accumulating heat, is the most dangerous one, although its small area prevents its disconnection from the thermal sensor. When dismantling the construction, the co-authors found out that the foil insulator had been melting in the area of maximal temperatures. Over the course of seven hours of operation, the temperature exceeded 120 ºC, and after that the odor of products of thermal decomposition of a synthetic product appeared.Conclusions. Despite all the features of advanced underfloor heating systems, their automated operation and transformation, they remain potentially flammable. Modern underfloor heating systems can take fire both as a result of violation of the fire precautions in case of non-compliance with the requirements for the operation of heating devices, and as a result of overheated film heaters located under the floor covering.
A new approach to calculating the time to the blocking of the escape routes due to the loss of visibility in the smoke of an indoor fire
Authors: Puzach S. V. , Mustafin V. M. , Akperov R. G.
Published: July 2021

Introduction. The accuracy of the visibility analysis in the event of an indoor fire strongly depends on the smoke-generating ability of substances and materials obtained experimentally in small-scale units. Therefore, the task is to develop a method of analysis that takes account of the scale factor and does not use the specific coefficient of smoke generation to identify the range of visibility in a full-scale room.Goals and objectives. The goal of the research project is a new approach to the calculation of the time to the blocking of the escape routes due to the loss of visibility with due regard for the scale factor and without regard for the specific coefficient of smoke generation. To achieve this goal, the analysis of fire development patterns in small-scale and full-scale rooms was carried out; theoretical dependences between the volumetric average optical smoke density and other volumetric average parameters of the indoor gas environment were obtained for these patterns, and calculation results, based on the obtained dependences, were compared with the experimental data.Methods. Methods, employed by the co-authors, included solving non-stationary equations based on the principle of conservation of indoor gas energy, optical density of smoke and oxygen mass for the cases of closed and open-type indoor heat and mass transfer. Fire tests were conducted in a small-scale facility. Theoretical and experimental data were compared.Results. Analytical dependences between the volumetric average optical density of smoke, a change in the volumetric average temperature, and the volumetric average partial oxygen density for closed and open indoor fire patterns were obtained. The series of fire tests involving the PVC insulated and sheathed bare (coverless) cable, exposed to the effect of the varying density incident heat flux, were carried out. Experimental dependences between the time, the optical density of smoke, and the specific coefficient of smoke generation were obtained. The obtained volumetric average optical density of smoke was compared with the experimental data using the proposed analytical expressions.Conclusions. The co-authors suggest using experimental dependences between the volumetric average optical density of smoke, changes in the volumetric average temperature or the volumetric average partial oxygen density obtained in a small-scale facility without solving the differential equation based on the principle of conservation of optical density of smoke.

Published: July 2021

Introduction.The problem of timely activation of fire sprinkler systems is highly relevant for effective fire suppression before the critical moment, when calculated values applied to extinguish the fire, become ineffective. A number of works address the problem of effective application of the fire sprinkler system to Class A fires. The application of such methods to Class B fires has not yet been considered.The model simulating a fire in a room with an automatic fire extinguishing system.The response time assessment model, developed by the co-authors for an automatic water-consuming fire sprinkler system, allows to identify the velocity of flame spreading over the surface of an HFL/CL spillage and the temperature rise rate in the ceiling area in the case of a B class fire.A sprinkler is triggered by the bulb bursting caused by the thermal effect produced by the ascending convection flow.A model has been developed to determine the response time of a fire sprinkler system exposed to the effect of a heat flow, caused by the Class B fire, on a heat-sensitive sprinkler bulb.Activation of a fire sprinkler system by the rate-of-rise heat detector.A model, designated for determining the activation time of a rate-of-rise heat detector, was developed.Examples.A number of examples, illustrating the response time of traditional, deluge, and forced launch fire sprinkler systems, are provided in the article.Conclusions.The obtained formula allows to quickly check the applicability of different types of fire sprinkler systems to ensure the effective protection of premises in which class B fires may break out.

Teaching grammar needs to be developed by the lecturer or the teacher. The lecturer must find out an alternative way to build good atmosphere in teaching grammar. Hence, one of the alternative ways is through visual illustration. This study examined the visual illustration towards the students’ grammar ability enhancement and the problems of the students in learning grammar and the solution. This study combined quantitative and qualitative method in answering the research questions. The instruments are grammar test and interview guideline. The result showed that visual illustration technique is effective in teaching grammar for students. It can be proved by the result of simple statistic calculation, where the score of significant is lower than 0.05 (0.00 < 0.05). Besides, students faced several problems in learning grammar, such as are misuse tenses, misuse modal auxiliary, misuse nominal and verbal sentence, and pronoun. The reason students faced those problems can be caused by the student itself, lecturer and inadequate knowledge.

Published: July 2021

Background: While pregnant women have been identified as a potentially
at-risk group concerning COVID-19 infection, little is known regarding
the susceptibility of the fetus to infection. Co-expression of ACE2 and
TMPRSS2 has been identified as a pre-requisite for infection, and
expression across different tissues is known to vary between children
and adults. However, the expression of these proteins in the fetus is
unknown. Methods: We performed a retrospective analysis of single cell
data repositories. This data was then validated at both gene and protein
level by performing qRT-PCR and two-colour immunohistochemistry on a
library of second-trimester human fetal tissues. Findings: TMPRSS2 is
present at both gene and protein level in the predominantly epithelial
fetal tissues analysed. ACE2 is present at significant levels, only in
the fetal intestine and kidney and is not expressed in the fetal lung.
The placenta is also negative for the two proteins both during
development and at term. Interpretation: This dataset indicates that the
lungs are unlikely to be a viable route of SARS-CoV2 fetal infection.
The fetal kidney, despite presenting both the proteins required for the
infection, is anatomically protected from the exposure to the virus.
However, the GI tract is likely to be susceptible to infection due to
its high co-expression of both proteins, as well as its exposure to
potentially infected amniotic fluid. Funding: This work was made

Catheter Ablation of Ventricular Tachycardia in LMNA Cardiomyopathy: Out of Sight but not Out of Mind
Authors: Halawa Ahmad , Zei Paul , Lakdawala Neal , Sauer William , Tedrow Usha , Kapur Sunil
Published: July 2021

Lamin Cardiomyopathy (LC) is associated with refractory ventricular
arrhythmias. Catheter ablation success rate is low due to presence of
multiple circuits and intramural substrate. We present a LC case
presented with electrical storm. During catheter ablation, arrhythmia
was easily inducible but activation mapping, including full epicardial
and endocardial mapping, failed to demonstrate the full tachycardia
cycle length (70% only) suggesting intramural activation. Critical
isthmus was not identified even with successful concealed entrainment on
both Endo/epicardial surfaces. This case shows that even combined
endocardial and epicardial catheter approach can be ineffective in
identifying the full arrhythmogenic substrate in LC.
Pleistocene expansion, anthropogenic pressure and ocean currents: Disentangling the past and ongoing evolutionary history of Patella aspera Röding, 1798 in the archipelago of Madeira

Rising sea-level following the Last Glacial Maximum lead to
fragmentation of coastal limpet populations between islands of the
Archipelago of Madeira. This fragmentation is reinforced by recent heavy
exploitation reducing effective population size on Madeira Island. We
use the limpet P. aspera to understand how the role of processes at
different time scales (i.e. changes in the sea level and
overexploitation) can influence the genetic composition of an extant
species, relating these processes to reproductive phenology and seasonal
shifts in ocean currents. Twelve microsatellite genetic markers were
used. A power analysis was used to evaluate the power of the
microsatellite markers to detect a signal of population differentiation.
Long-term past migrations were assessed using a Bayesian Markov
Montecarlo approach in the software MIGRATE-n to estimate
mutation-scaled migration rates (M = m/μ; m, probability of a lineage
immigrating per generation; μ, mutation rate). Two scenarios were
evaluated using an Approximate Bayesian Computation (ABC) in the
software DIYABC 2.1 (i) Scenario 1: considered a population scenario
from a reduced Ne at time t3 to a higher Ne at time t2; and (ii)
Scenario 2 considering a reduction of Ne from a time t3 to a time t2.
Colonization of the archipelago by Portuguese settlers six centuries ago
probably led to an important decrease in the genetic diversity of the
species (Ne). Contemporary gene flow strongly support a pattern of high
asymmetric connectivity explained by the reproductive phenology of the
species and spatio-temporal seasonal changes in the ocean currents.
Spatio-temporal reconstructions using Bayesian methods, including
coalescent and Approximate Bayesian Computation (ABC) approaches,
suggest changes in the migration patterns from highly symmetric to
highly asymmetric connectivity with subtle population differentiation as
consequence of post-glacial maximum sea level rise during the Holocene.
Adventitious rooting in response to long-term cold: a possible mechanism of clonal growth in alpine perennials
Authors: Mishra Priyanka , Vayssieres Alice , Roggen Adrian , Ljung Karin , Albani Maria
Published: July 2021

Arctic alpine species experience extended periods of cold and
unpredictable conditions during flowering. Thus, often, alpine plants
use both sexual and asexual means of reproduction to maximise fitness
and ensure reproductive success. We used the arctic alpine perennial
Arabis alpina to explore the role of prolonged cold exposure on
adventitious rooting. We exposed plants to 4°C for different durations
and scored the presence of adventitious roots on the main stem and
axillary branches. Our physiological studies demonstrated that the
presence of adventitious roots positively correlates with increased
duration of exposure to cold treatment, with 21 weeks at 4 °C saturating
the effect of cold on adventitious rooting. On the main stem
adventitious roots developed in specific internodes. Transcriptomic and
histological studies indicated that adventitious roots in A.
alpina stems are initiated during cold exposure and emerge after plants
experience growth promoting conditions. The emergence of the
adventitious root primordia correlates with an increase in auxin
response and free endogenous auxin in the stems. Our results highlight
the role of low temperature during clonal growth in alpine plants and
provide insights on the molecular mechanisms involved at different
stages of adventitious rooting.
Spacetime estimates and scattering theory for quasilinear Schrodinger equations in arbitrary space dimension
Authors: song xianfa
Published: July 2021

In this paper, we consider Cauchy problem of a quasilinear Schrodinger
equation which has general form containing potential term, power type
nonlinearity and Hartree type nonlinearity. The space dimension is
arbitrary, that is, it is larger than or equals to one. First, we
establish the local wellposedness of the solution and discuss the
condition on the global existence of the solution. Next, we establish
some conservation laws such as mass conservation law, energy
conservation law, pseudoconformal conservation law of the solution.
Based on these conservation laws, we give Morawetz type estimates,
spacetime bounds for the global solution. Last, we take two ideas to
establish scattering theory for the global solution in different
functional spaces. The first idea is that we take different admissible
pairs in Strichartz estimates for different terms on the right side of
Duhamel’s formula in order to keep each term independent, another one is
that we factitiously let a continuous function be the sum of two
piecewise functions and choose different admissible pairs in Strichartz
estimates for the terms containing these functions.
Plants as alternative platforms for monoclonal antibodies productions.
Authors: Glumińska Natalia , Krzesłowska Magdalena
Published: July 2021

Monoclonal antibodies (mAbs) are widely used in medical therapy and
diagnostics, veterinary therapy, and research. The demand for mAbs
reaches several dozen tons per year and is constantly growing,
approaching the limits of current production possibilities. Mammalian
expression systems, which currently dominate the bioproduction industry,
have limited production capacity and require high capital investment and
production costs. Plants are becoming promising expression platforms due
to their scalability, speed, low cost of production, low risk of
contamination from animal pathogens and eukaryotic mechanisms of
post-translational protein modification. The transgenic plants used for
the production of mAbs can be obtained by stable transformation of plant
cells as well as transient expression of foreign proteins. In this
review, we extract a broad overview of articles, many of them from
recent years, concerning modern approaches to producing monoclonal
antibodies in plants, methods for modifying the carbohydrate profile of
mAbs, and purifying the resulting product. We also present current data
on the practical use of mAbs in medical therapies and potential methods
of producing antibodies on a very large scale, able to meet the future
market demand.

Long-term optical photometric monitoring of the FUor star V900 Mon

Published: July 2021

We present results from photometric monitoring of V900 Mon, one of the newly
discovered and still under-studied object from the FU Orionis type. The
FUor phenomenon is very rarely observed, but it is essential for stellar
evolution. Since we only know about twenty stars of this type, the study of
each new object is very important for our knowledge. Our data were obtained
in optical spectral region with the BVRI Johnson-Cousins set of filters
during the period from September 2011 to April 2021. In order to follow the
photometric history of the object, we measured its stellar magnitudes on
available plates from the Mikulski Archive for Space Telescopes. The
collected archival data suggest that the rise in brightness of V900 Mon
began after January 1989 and the outburst goes on so far. In November 2009,
when the outburst was registered, the star had already reached the level of
brightness close to the current one. Our observations indicate that during
the period 2011-2017 the stellar magnitude increased gradually in each pass
band. The observed amplitude of the outburst is about 4 magnitudes (R).
During the last three years, the increase in brightness has stopped and
there has even been a slight decline. The comparison of light curves of the
known FUor objects shows that they are very diverse and are rarely repeated.
However, the photometric data we have so far show that V900 Mon's light
curve is somewhat similar to those of V1515 Cyg and V733 Cep.
Epistaxis

Published: July 2021

Epistaxis, also known as nosebleeds, is a commonly treated condition in medicine and especially otolaryngology. 1 in 200 emergency room visits are due to acute epistaxis, with a higher frequency during the winter and among young children and the elderly. A strong understanding of the etiology, anatomy, and available therapeutic options is necessary for optimal management of epistaxis.1,2
