Smoking remains a worldwide health hazard. Smokers don't only put themselves at risk of serious health problems, but people around them arealso exposed to such potential danger. This passive exposition iscalled: Second Hand Smoke (SHS).To limit the SHS contamination in an Environmental Tobacco Smoke a new “Healthy Second Hand Smoke (HSHS)” device was developed. In this paper,we will explainthe functioningbasics of the HSHS device. It ismainly based on an insulatedsmoke compartment with transparent view, placed in the area where smokers and non-smokers exist together. Smoker inhalesand exhalessmoke through an“HSHS”accessory called “hand”which is related to the compartment by two hoses.In this compartment, an aspiration system is used to evacuate the smoke. Theefficiencyof the “HSHS”deviceis thenevaluated. For four hookah smokers, the Carbonemonoxide gas concentration was measured during 30 min in a5.3m3unventilatedexperimentalroom. A comparison was made between the smoke concentration in the unventilated room, with and without the use of the HSHS device.Statistical tests were performed in order to insure the validity of the results thatwere taken for four smokers only.The results showthat the use of HSHS device reduces second hand hookahinhalationsmoke, in a 5.3 m3unventilated room, by95.9% ± 28.2%, 91.8% ± 37.5%, 97.8% ± 15.7% and 98.5% ± 66.2% during 10, 15, 20 and 25 minutesrespectively.As aconclusion, this new smoking concept opens the way forless invasive smoking habitsin crowded environments.

The paper provides an empirical analysis of Lebanon’s merchandise trade deficit and thecurrent accountfor the 1969-2016 period. Using the Auto-Regressive Distributed Lag approach, it estimatesstandard demand functions for merchandise exports and imports and the trade deficit.The results show that real exchange rates do not have a long-run impact on exports, imports, the trade deficit, and the current account; domestic production has a notableeffect on reducing trade deficits while absorption expenditures, primarily public expenditures, have a strong effect on increasing trade deficits. The main three conclusions and policy implications that emerge from the analysis are: first, the Central Bank of Lebanon’s policy of fixing the exchange rate in the post-war period has not harmed competitiveness and has proved to be a strong basis for monetary stability; second, a more active industrial and investment policy is needed to enhance competitiveness and export promotion and to increase and diversify domestic production; and third, public expenditures ought to be urgently rationalized and conducted within a framework of sound fiscal and governance reforms.
Application of the model of cylindrical reactor for self-purification by indigenous microorganisms
Authors: Radonjic Drazana
Published: March 2021

Pharmaceutically active compounds (PhACs), in particular, nonsteroidal antiinflammatory drugs (NSAIDs) are in increasingly wider usage, and as such are more and more frequently part of the organic matter of recipient rivers, especially in their lower courses. To indicate their significance as pollutants, as well as the significant role that the presence of autochthonous microflora plays in solving this issue, we undertook to perform this experiment. The experiment, titled ?Application of the model of cylindrical reactor in self-purification by indigenous microorganisms?, was conducted during a one-year period at the location of Vukovci, in the lower course of the Moraca river. Assuming that the concentration of NSAIDs and PhACs in water can be reduced through selfpurification, it has been proven that such processes result in a modification of phenotype in the indigenous microbiological population. Having the abovementioned premise in mind, we constructed the experiment model, which entails kineticism of water, whereas the defined volume flow rate per unit time was 0.005 m/s, through the known distance of 432 m. Over one year of application of the model of the cylindrical reactor for enhancing self-purification capacity by indigenous microorganisms, auto-purification increased by 28.05%, the phenotype of the indigenous microorganisms changed by 24.62%, whereas the total concentration of particular PhACs, micropollutants, and NSAIDs decreased by 4.19%.

Published: March 2021

Cooling water of Heavy Ion Research Facility in Lanzhou is the media of
choice for absorbing heat generated by a multitude of accelerator
components. During the operation, tritium is produced by the secondary
neutrons in the accelerator loop of accelerator cooling water, which is
uniformly distributed in the water system in the form of hydrogen tritium
oxide. The purpose of this study is to establish a rigorous method to
measure the low levels of tritium in the accelerator cooling water system.
The cooling water samples of Sector Focusing Cyclotron and Separated
Sector Cyclotron of Heavy Ion Research Facility in Lanzhou, as well as the
natural levels of tritium, were measured successfully, using Quantulus1220
ultra-low-level background liquid scintillation spectrometer. The
electrolytic enrichment method was employed to measure the tritium activity
concentrations of the cooling water samples. Moreover, the minimum
detectable activity concentration and the counting rate efficiency curve of
the liquid scintillation spectrometer were obtained to ensure reliability.
In this work, we provide a reference to establish the related standards
and specifications for monitoring the tritium levels in heavy-ion
accelerator cooling water system.

The aim of the study was to evaluate the potential risks of radiation near
abandoned uranium mines, tailing dumps, or uranium deposits on Mountain
Stara Planina, Serbia. For risk assessment several parameters were
determined: radium equivalent activity, Raeq, external hazard index, Hex, gamma radiation absorbed dose rate, D, annual effective dose on background outdoor gamma exposure,
AEDoutdoor, and excess lifetime cancer risk, ELCR.
Obtained results showed that all the samples, except one, have the
Raeq value up to two times higher than the reference limit. The Raeq of
the sample from the Mezdreja mine tailings was increased by almost eight
times. The value of Hex followed the same pattern as Raeq. All the investigated
localities have increased D values, while all the samples have shown
the moderately low AEDoutdoor, except Mezdreja mine tailings that have
5.5-2.8 times higher dose relative to the world's average. ELCR at the
Mezdreja mine tailings is 4.58 times higher than the world's average of
1.45?10?3. In the context of human activity in the area of Stara Planina
such as different kinds of tourism, livestock breeding, dairy products, and
herbal manufacturing, etc. there is a need for detailed analysis in order to
evaluate potential human exposure and health impacts.

should include information related to radiation exposure. The aim of this
work is to present the patient radiation dose assessment system designed for
routine clinical use, that uses in-house designed worksheets for dose
calculation based on relevant parameters introduced by the ICRP
publications. Dose reports provide information about the absorbed dose
delivered to the target and non-target organs of interest and the effective
dose for each diagnostic procedure. The data from the dose reports was used
to investigate average patient exposure levels during a one-year period and
the results are presented. The implemented system has improved the quality
of services provided and understanding of radiation risks. Moreover, the
presented results have stimulated further optimization of nuclear medicine
processes.

Published: March 2021

For optical fibre sensors applications, nanomaterials have been widely used to enhance sensor performance. Here, the fibre optic uses the transmission of light by total internal reflection along with the fibre and depending on the diameter of the fibre and the wavelength of the light used. Among others, graphene oxides nanostructures (GO) would offer exceptional advantages on the sensing mechanism due to 2D properties of the monocellular layer originally from graphite. The main objectives of this research are to successfully synthesis of GO using a chemical reduction method known as modifies Hummer’s method and later, deposited the GO onto the modified fibre optic layer to create a sensing platform. Prior than that, the standard plastic of fibre optic (POF) was modified by removing the cladding layer (1 cm) using a mechanical etching technique, thus the sensing platform can be created. The morphology and optical properties of the system were characterised using scanning electron microscopy (SEM) and ultraviolet-visible (UV-Vis) spectroscopy. Result of the preparation and characterisation of GO-optical fibre coatings was presented, considering its potential use for sensing applications. The stable GO was prepared by 3 hours of stirring time during the synthesis and longer dipping time was preferred to fully coat the core of the exposed POF. Aiming to explore this scheme for sensing applications, GO-coated tilted fibre will be later measuring via refractive index variations. An improvement on the sensitivity should be obtained and thus become a promising sensing platform for the development of a new line of sensors.

I study the effectiveness of fault-tolerant quantum computation against correlated Hamiltonian noise, and derive a sufficient condition for scalability. Arbitrarily long quantum computations can be executed reliably provided that noise terms acting collectively on $k$ system qubits are sufficiently weak, and decay sufficiently rapidly with increasing $k$ and with increasing spatial separation of the qubits.
Gaming the quantum
Authors: Khan Faisal Shah , Phoenix Simon J.D.
Published: March 2021

In the time since the merger of quantum mechanics and game theory was proposed formally in 1999, the two distinct perspectives apparent in this merger of applying quantum mechanics to game theory, referred to henceforth as the theory of ``quantized games'', and of applying game theory to quantum mechanics, referred to henceforth as ``gaming the quantum'', have become synonymous under the single ill-defined term ``quantum game''. Here, these two perspectives are delineated and a game-theoretically proper description of what makes a multiplayer, non-cooperative game quantum mechanical, is given. Within the context of this description, finding Nash equilibrium in a zero-sum quantum game is exhibited to be equivalent to finding a solution to a simultaneous distance minimization problem in the state space of quantum objects, thus setting up a framework for a game theory inspired study of ``equilibrium'' behavior of quantum physical systems such as those utilized in quantum information processing and computation.
Non-monogamy of quantum discord and upper bounds for quantum correlation
Authors: Ren Xi-Jun , Fan Heng
Published: March 2021

We consider a monogamy inequality of quantum discord in a pure tripartite state and show that it is equivalent to an inequality between quantum mutual information and entanglement of formation of two parties. Since this inequality does not hold for arbitrary bipartite states, quantum discord can generally be both monogamous and polygamous. We also carry out numerical calculations for some special states. The upper bounds of quantum discord and classical correlation are also discussed and we give physical analysis on the invalidness of a previous conjectured upper bound of quantum correlation. Our results provide new insights for further understanding of distributions of quantum correlations.

Orientation Averaging of Optical Chirality Near Nanoparticles and Aggregates
Authors: Fazel-Najafabadi A , Schuster S , Auguié Baptiste
Published: March 2021

Artificial nanostructures enable fine control of electromagnetic fields at the nanoscale, a possibility that has recently been extended to the interaction between polarised light and chiral matter. The theoretical description of such interactions, and its application to the design of optimised structures for chiroptical spectroscopies, brings new challenges to the common set of tools used in nano-optics. In particular, chiroptical effects often depend crucially on the relative orientation of the scatterer and the incident light, but many experiments are performed with randomly-oriented scatterers, dispersed in a solution. We derive new expressions for the orientation-averaged local degree of optical chirality of the electromagnetic field in the presence of a nanoparticle aggregate. This is achieved using the superposition T -matrix framework, ideally suited for the derivation of efficient orientation-averaging formulas in light scattering problems. Our results are applied to a few model examples, and illustrate several non-intuitive aspects in the distribution of orientation-averaged degree of chirality around nanostructures. The results will be of significant interest for the study of nanoparticle assemblies designed to enhance chiroptical spectroscopies, and where the numerically-efficient computation of the averaged degree of optical chirality enables a more comprehensive exploration of the many possible nanostructures.
Designing with Mycelium: Utilising spatial printing to create scaffolds for mycelium growth
Authors:   , Koetsier Elize
Published: March 2021

With increased awareness of the environmental impact of synthetic materials, there has been an increase in research investigating more sustainable manufacturing methods and materials. Making appropriate sustainable material choices for designs is becoming essential, whether it is using more durable or adaptable materials that will last an extended period or integrating sustainable bio-materials into short-term products. In addition, there are a number of research projects that use natural growing systems to produce materials with placement being defined by 3D printing or digitally fabricated moulds. These have been referred to as Hybrid Construction Systems, as both natural and manmade techniques are combined as a fabrication system. This research portfolio investigates the opportunities and constraints of using mycelium-based composites in combination with spatially printed structures to dictate the form, materiality and potential use.

Mycelium offers many unique material qualities, it is a naturally occurring resource that can perform as a structurally sound material when used correctly. One benefit of it beyond removing the use of synthetic materials is that it can be composted, when it is no longer needed, which could offer sustainable design alternative for short-term products or for large temporary structures.

There are a number of recent projects that have focused around the use of mycelium in an architectural context, one being Mycotree which created a load-bearing structure from mycelium composite blocks that were generated through 3D graphic software (Heisel et al., 2017). A common trait of these projects and others, is that the method of making used a process of growing the composite in engi- neered moulds and later assembled.

This research explored the creation of spatially printed 3D scaffolds and the synergies of materials, methods of growth and manipulation of mycelium based composites. Form, pattern, and structure of 3D printed objects were analysed along with application techniques to identify suitability for mycelium growth. Processes identified as successful were then applied to the design of large scale structures that highlighted the opportunities of the developed method.
The findings in this report provide evidence that spatial printing could offer a scaffold for mycelium composites to grow, defining form and strength, creating an alternative method and unique design opportunities to the traditional use of casting moulds. This research portfolio presents the possibility for innovative manufacturing methods that adopt a collaboration between digitally defined forms and bio-materials, exploiting the freedom and accuracy of digital design while using highly sustainable materials.

Objective. To determine the impact of the mitral valve insufficiency in patients, suffering ischemic heart disease with lowered contractility of left ventricle and methods of its treatment. Materials and methods. During 01.01.2015-31.12.2018 yrs period in the Amosov National Institute of Cardiovascular Surgery there were conducted 2267 consecutive operations of coronary shunting, of them 190 (8.4%) - in patients, suffering the ischemic heart disease with lowered contractility of left ventricle. Reduction of the output fraction of left ventricle down to 35% and lower have served as criterion of inclusion of the patients into the Group. There were 170 (89.5%) men and 20 (10.5%) women. The patients’ age have constituted 29 - 83 yrs old, (61.1 ± 8.9) yrs old at average. Results. In 47.9% of the patients the lowering of the left ventricle contractility after myocardial infarction was followed by occurrence of regurgitation on a mitral valve. At the same time it was noted, that the regurgitation value have had correlated with degree of the left ventricle contractility lowered: in reduction of values of the left ventricle output fracture down to 25% and lower a moderate regurgitation on a mitral valve was registered up to 2 times, a significant one - in 2.5 times, and the pronounced one - in 1.5 times more frequently, than in values of the left ventricle output fracture, exceeding 25%. Occurrence of a mitral insufficiency in 18.7% patients was caused by direct damage of valvular apparatus, while in 81.3% patients the consequences of the heart cavities were present in disorder of contractile function of myocardium. Presence of postinfarction mitral insufficiency enhances the risk of an acute cardiac insufficiency in 1.7 times and necessitates intraoperative correction in values of the regurgitation fraction over 30%. Conclusion. The own data obtained witness, that noncorrected mitral insufficiency in the ischemic heart disease worsens significantly the postoperative period course after performance of coronary shunting, enhancing rate of an acute cardiac, respiratory and renal insufficiency. Thus, taking into account a negative impact of concomitant mitral valve insufficiency on efficacy of surgical interventions in the lowered contractility of left ventricle the need emerges to perform complex reconstructive intervention in patients, suffering ischemic heart disease with lowered contractility of left ventricle.
GENERATION OF NEW OPERATIONAL MATRICES FOR DERIVATIVE, INTEGRATION AND PRODUCT BY USING SHIFTED CHEBYSHEV POLYNOMIALS OF TYPE FOUR

Published: March 2021

While solving the fractional order differential equation the requirement of the higher-order derivative is obvious therefore, this paper gives a definite expression for constructing the operational matrices of derivative which is the direct method to find the derivative of higher-order according to the requirement of the total differential equation. The proposed work expands the Chebyshev polynomial of type four up to six degrees that could help get the accuracy for the numerical solution of a given differential equation. Previously Chebyshev polynomial of the third type has been used by cutting the domain from [-1, 1] to [0, 1]. This study also generates the integrational operational matrix for solving the integral equation as well as an integrodifferential equation by using the Chebyshev polynomial of type four and expand it up to six order and generate the matrix by cutting the domain from [-1, 1] to [0, 1]. This is the first attempt to generate an integrational operational matrix that has never been highlight nor generate by any researcher. Another contribution of this paper is the generation of categorical expressions for the product of two Chebyshev vectors that will help in solving the differential equation of several kinds.
Vibration Response of a Monumental Stair: Design & Validation

Published: March 2021

Monumental stairs are a common feature in buildings throughout New York City, as they provide both a practical means of egress and an aesthetic impact. It is often desired to make these stairs appear as light as possible, and as a result they are especially susceptible to excessive human-induced vibrations. While not a strength limit state, stair vibrations must nonetheless be limited to satisfy tolerance criteria for human comfort. The updated second edition of AISC Design Guide 11 includes new guidance for prediction and evaluation of stair vibration, including recommendations for finite element analysis. Thornton Tomasetti has developed a tool for analysis of stair vibration based largely on these recommendations, and numerous monumental stairs have been designed using this approach. One such stair is located in the NewYork- Presbyterian David H. Koch Center. Following its completion, a test program was implemented to measure the dynamic properties and response of the stair and compare with the design predictions. This paper describes the structural design of the stair and overviews the analytical approach used to predict the stair vibration response. The test program employed to measure the actual vibration response of the completed stair is also described, and the predicted and experimental vibration responses are compared.
Engineering as a Prerequisite for Growth: New York and its Infrastructure
Authors: Ennis Marie , Friedman Donald
Published: March 2021

As a world city, New York is famous for many reasons; as a large city located primarily on islands at a complex of rivers, bays, and tidal straits, it has long depended on structural engineering for viability. Prominent structures include underwater vehicular and rail tunnels, bridges of every structural type, and aqueducts. Ten diﬀerent buildings have held the world record for height, two arch bridges have held the world record for span, and four diﬀerent suspension bridges have held the world record for their main span. With a multitude of successful businesses and the physical constraints of the geography, the motivation for technical innovation were present, and engineers were ready for the challenges.

These structures have generally not been built because they would break records, but rather because they served a purpose. For example, the Brooklyn Bridge, with a center span ﬁIy percent longer than the second- longest at the time of its construction, was built because ferries were the only transportation between New York and Brooklyn, then the ﬁrst and third largest cities in the country. There is a close correlation, decade by decade and beginning in the 1880s, between what was feasible in terms of structural engineering and what has been built to enable the city to grow and prosper. This paper will examine that correlation and engineers’ role in the city’s evolution.
Diagnostics and monitoring of the longest span extradosed bridge in Europe
Authors: Miśkiewicz Mikołaj , Wilde Krzysztof
Published: March 2021

The article presents complex diagnostic procedures applied for the purpose of behavior analysis of the extradosed bridge with the longest span in Europe that was built in 2018 in Poland. The system of health monitoring was used to: register internal forces in temporary supports, monitor concrete bonding, perform in situ diagnostics and operation tests. The bridge is a continuous four‐span structure with spans theoretical lengths equaling: 132.5+206.0+206.0+132.5 m. During the construction of the bridge, two technical monitoring systems were used. As a consequence of their application, it was possible to carry out works with the lowest level of risk and therefore the work schedule was accelerated. The first of systems was designed to measure forces transferred to temporary supports during cantilever construction stages. The second system was designed to measure changes of the strength of curing concrete, after it was poured at the site, which allowed to speed up the removal of the scaffoldings and post‐tension of cross section with cables. When the bridge was finished, a Structural Health Monitoring (SHM) system was installed and final acceptance tests were launched. The obtained results were used to validate theoretical assumptions done at the stage of the bridge structural design and provided insight into the complex bridge behavior.
Inducing behavioural change in transportation - mobilizing human ressource
Authors: Ernst Christian
Published: March 2021

According to the UN department of Economy and Social affairs, 68% of the world’s population will be living in urban areas by 2050 [1]. Since urban areas represent the coming together of different transport modes on limited space, it is a transportation environment with an inherent high probability of clashes. These clashes are known to occur between different groups, e.g. pedestrians and cyclists.

In the Scandinavian countries, cycling is taking on an impressive cut of overall transport volume. Copenhagen has experienced a steady rise in bicycle traffic throughout the past decades –as recent data confirms [2].

Copenhagen has been the model case for Scandinavian and other cities to look at how to increase bicycle traffic. However, with the e-bike and other battery driven devices such as speed-pedelecs on the rise, the system as we know it is threatened. It is necessary to raise awareness for this change and induce behavioral change with the so-called “soft” traffic users. What are the recent findings in this field and what challenges are identifiable. What can be done in order not to put a positive development under threat?

Bridge inspection is essential for sustaining safe and well-performing transportation networks. The Ministry of Transportation of Ontario (MTO) bi-yearly inspects over 2800 bridges in Ontario, Canada. Then assigns each bridge a Bridge Condition Index (BCI) representing its performance level and required rehabilitation.As this is a time and resources consuming practice, this study explores the BCI trends which can allow a better control on inspection and maintenance scheduling. First, statistical analysis is conducted to identify the correlation of the bridge parameters with the BCI. The analysis reveals that the main parameters associated with BCI are bridge age, and time since last major and minor maintenances. Then, multivariate regression analysis is performed to establish a BCI prediction equation function of these parameters. The proposed framework can supplement existing practices for smarter inspection and maintenance scheduling.
