Multiobjective optimisation and cluster analysis in placement of best management practices in an urban flooding scenario
Authors: Dwivedula Rohit , Madhuri R. , Srinivasa Raju K. , Vasan A. 
Published: July 2021

Abstract
This research is being carried out to study how best management practices (BMPs) can mitigate the negative effects of urban floods during extreme rainfall events. Strategically placing BMPs throughout open areas and rooftops in urban areas serves multiple purposes of storage of rainwater, removal of pollutants from surface runoff and sustainable utilisation of land. This situation is framed as a multiobjective optimisation problem to analyse the trade-offs between multiple goals of runoff reduction, construction cost and pollutant load reduction. Output includes a wide range of choices to choose from for decision makers. Proposed methodology is demonstrated with a case study of Greater Hyderabad Municipal Corporation (GHMC), India. A historical extreme rainfall event of 237.5 mm which occurred in 2016 and extreme rainfall event of 1,740.62 mm corresponding to representative concentration pathway (RCP) 2.6 were considered for analysis. Two multiobjective optimisation algorithms, namely non-dominated sorting genetic algorithm-III (NSGA-III) and constrained two-archive evolutionary algorithm (C-TAEA) are used to solve the BMP placement problem, following which the resulting Pareto-fronts are ensembled. K-Medoids-based cluster analysis is performed on the resulting ensembled Pareto-front. The proposed ensembled approach identified ten possible BMP configurations, with costs ranging from Rs. to surface runoff reduction ranging from to and pollutant load removal ranging from tonnes. Use of BMPs in future events has the potential to reduce surface runoff from , while simultaneously removing tonnes of pollutants for cost ranging from The proposed framework forms an effective and novel way to characterise and solve BMP optimisation problems in context of climate change, presenting a view of the urban flooding scenario today, and the likely course of events in the future.

Authors: Xu Ke , Wang Bingge 
Published: July 2021

:
Atomic force microscope (AFM) has become the main tool for observation and manipulation
in nanotechnology research due to its nano-meter high resolution, but the slow imaging speed is
one of the important reasons hindering the further development of AFM. This article first introduces
the applications of AFM in cell biology in recent years, expresses the importance of rapid imaging in
cell biology, and then summarizes the reasons affecting the imaging speed of AFM from three aspects:
the limited bandwidth of system mechanical components, obvious inherent characteristics of
piezoelectric scanners, and complex image processing algorithms. The improvement and optimization
methods of mechanical parts or structure, control algorithm and image processing are reviewed
for different influence reasons. Then, the advantages and of different improvement methods, as well
as the improved imaging speed and imaging quality improvement effects, are compared. Imaging
speed and resolution are both several to dozens of times higher than before, while ensuring image
quality and without damaging the samples. The aim of this review is to enable students, the public
and even experts of different knowledge backgrounds to learn directly, and select realizable improvement
methods according to realistic conditions. Finally, the future development trend and further
prospects of high-speed AFM are discussed.
Type 2 Diabetes Mellitus Related to Decreased Peripheral and Respiratory Muscle Strength in Sarcopenic Thai Elderly
Authors: Yuenyongchaiwat Kornanong , Boonsinsukh Rumpa 
Published: July 2021

Background:
Age is related to a decline in muscle mass and physical function in both respiratory
and peripheral muscle strength, which could lead to mobility and mortality. In addition,
older people have suffered from one or multiple chronic conditions in particular in type 2 Diabetes
Mellitus (type 2 DM). However, a few studies have reported the relationship between sarcopenic
elderly and respiratory and peripheral muscle strengths in type 2DM.

Objective:
To explore the prevalence of sarcopenia in type 2 DM elderly people among community-
dwelling patients and the relationships with peripheral and respiratory muscle loss in sarcopenic
type 2 DM older patients.

Methods:
A total of 330 older individuals were recruited from community-dwelling centers. Respiratory
muscle and quadriceps muscle were assessed. According to the defined criteria for sarcopenia
(defined by Asian Working Group for Sarcopenia), muscle mass, gait speed (six-meter walk
test), and handgrip strength were examined.

Results:
Of 330 elderly people, 82 volunteers had a history of type 2 DM. Participants with type
2DM had a risk for sarcopenia (odds ratio= 2.324, 95% CI=1.251-4.317). The prevalence of sarcopenia
was 25.61% among older participants with type 2 DM. In addition, decreased respiratory
muscle strength and quadriceps muscle strength were observed in type 2 DM with sarcopenia compared
to type 2 DM with non-sarcopenia. These relationships also remained after controlling for
age and sex.

Conclusion:
Sarcopenia in type 2 DM leads to a decrease in respiratory muscle and peripheral muscle
strength.

Published: July 2021

Background:
Cadmium sulfide (CdS) based semiconductors are of great interest for different
high-end applications because they pose a direct bandgap (2.42 eV). CdS are used as the main
constituent material in many applications, namely solar cells, electroluminescent, and quantum dot
light-emitting diodes. Transition metal-doped CdS revealed considerable influence in the bandgap,
photoluminescence properties and peak energy upon increasing the metal content.

Objective:
In this work, we study the single-phase cubic structure of CdS. Photoluminescence spectra
revealed a strong blue emission peak located at about 445 nm.

Methods:
We investigate the Co-doping CdS semiconductor nanoparticles prepared via the chemical
co-precipitation method using thiophenol as template, 300 °C/2h in vacuum optimum temperature and
period of annealing to yield nanosized particles. Morphology and structural studies of the particles
were using XRD, and TEM, respectively.

Results:
XRD and TEM studies for the calcined samples revealed a cubic structure. The crystalline
size was in the range of 10-17 nm. Thermogravimetric analysis (TGA) was employed to stabilize the
temperature of annealing for the samples. The blue shift in the spectra and the band gap value of Codoped
CdS nanoparticles were estimated using UV-vis absorption spectra. Photoluminescence spectra
revealed a strong blue emission peak around 445 nm indicating the presence of surface states within
the bandgap region, which is a characteristic feature of nanoparticles.

Conclusion:
XRD analysis indicated zinc blend structure and the intensity decreased with increasing
Co content. TEM images show that the particles are spherical in shape with average sizes around 13
nm. Luminescence of the synthesized nanoparticles exhibited blue emission between 400 – 500 nm
with the peak located at about 445 nm. The emission intensity increased with the increase in Co concentration.
CO2 mineralization of demolished concrete wastes into a supplementary cementitious material – a new CCU approach for the cement industry
Authors: Zajac Maciej , Skocek Jan , Skibsted Jørgen , Ben Haha Mohsen 
Published: July 2021

This contribution discusses the carbon capture and utilization (CCU) approach based on CO2 mineralization of cement paste from recycled concrete as new approach to capture CO2 and significantly contribute to the reduction in CO2 emissions associated with cement production. The current literature suggests that all CO2 released from the decomposition of limestone during clinker production can be sequestered by carbonation of the end-of-life cement paste. This carbonation can be achieved in a few hours at ambient temperature and pressure and with a relatively low CO2 concentration (< 10 %) in the gas. The carbonation of cement paste produces calcite and an amorphous alumina-silica gel, the latter being a pozzolanic material that can be utilized as a supplementary cementitious material. The pozzolanic reaction of the alumina-silica gel is very rapid as a result of its high specific surface and amorphous structure. Thus, composite cements containing carbonated cement paste are characterized by a rapid strength gain. The successful implementation of this CCU approach relies also on improved concrete recycling techniques and methods currently under development to separate out the cement paste fines and such. Full concrete recycling will further improve the circular utilization of cement and concrete by using recycled aggregates instead of natural deposits of aggregates. Although the feasibility of the process has already been demonstrated at the industrial scale, there are still several open questions related to optimum carbonation conditions and the performance of carbonated material in novel composite cements.

Published: July 2021

The principles ruling foreigners' expulsion in the light of the jurisprudence of the ECHR, of the ICJ and of the practice of the UN control bodies. Expulsion as a measure for the removal of foreigners from a State is governed by number of principles, which must be respected by the State having resorted to expulsion. First, we note that a State has the power to expel a foreigner from its territory, because of its sovereign power on grounds of public order, national security, or the illegal stay of the foreigner. But this expulsion is regulated by international law through a number of principles. However, the power of State in this matter is not unlimited. Thus, any decision to expel must be in accordance with the law, the State is not allowed to resort to collective expulsion, moreover, a State should only expel the foreigner to another State which is safe of origin which is safe, to prevent the foreigner from being subjected to torture.

Authors: Li Ligang , Pei Zhiyuan , Jin Jiucai , Dai Yongshou 
Published: July 2021

Abstract
In order to improve the accuracy and robustness of path following control for an Unmanned Surface Vehicle (USV) suffering from unknown and complex disturbances, a variable speed curve path following a control method based on an extended state observer was proposed. Firstly, the effect of the environmental disturbances on the USV is equivalent to an unknown and time-varying sideslip angle, and the sideslip angle is estimated by using the extended state observer (ESO) and compensated in the Line of Sight (LOS) guidance law. Secondly, based on the traditional LOS guidance law, the design of the surge velocity guidance law is added to enable the USV to self-adjust the surge velocity according to the curvature of the curve path, thus further improving the tracking accuracy. Finally, the heading and speed controller of the USV is designed by using a sliding mode control to track the desired heading and speed accurately, and then the path following control of the USV’s curve path is realised. Simulation results verify the effectiveness of the proposed method.

Authors: Kozak Janusz 
Published: July 2021

Abstract
Steel sandwich structures are perceived as alternatives to single-skin welded structures in the shipbuilding industry due its advantages like significant reduction of mass in relation to typical single skin structure. However, beside problems with their strength properties itself, applications in real structures requires of solving the problem of joining, both for connection sandwich to sandwich as well as sandwiches to single-shell structures. Proper design of joints is connected with some factors like lack of attempt to interior of panel, introduction of additional parts and welds with completely different stiffness. In the paper the results of laboratory fatigue tests of selected joints as well as numerical calculation of stressed for different kind of joints of sandwich structures are presented. As result of calculations optimisation of geometry for selected joints is performed.

Published: July 2021

Abstract
The circular economy is an approach to help reduce global sustainability pressures. In circular economy it is important to involve design from the beginning of the product lifecycle, including product ideation and material selection. Involvement of consumers and users into circular economy is very important and enables change in purchase patterns and product utilization. The paper methodology consists of a profound literature review and analysis in area of circular economy, circular design and consumer or user influence on circularity. The goal of the paper is to provide insights into the consumer involvement into a circular economy and changes in users’ behavior. The research results in discussion of design strategies to slow down “resource loops”, to close “resource loops”, and to “narrow material flow” to enhance circular economy and business models, as well as consumer involvement in circular economy. We outline desired consumer and user behavior leading to circular economy.

The Examination of Food Waste Behaviour in Hungarian Households
Authors: Borbély Csaba , Gőbel Rebeka 
Published: July 2021

Abstract
Our current existence on the Earth raises a number of contradictions such as our relation to food. According to the FAO, a third of the food produced does not reach consumers; according to calculations by the World Resources Institute, even if we reduced losses by a quarter, 795 million people would have enough food to feed. This controversial situation gives topicality to the topic, which will only grow as the Earth’s population grows by about 80 million people a year and our resources for nourishment are finite. In our research we focused on households within the topic area of food waste generated in the supply chain. This focus of research is considered a difficult one because results could be found only with data logging and this method has several limitations which could distort the results. In our research, 20 households in Kaposvár were asked to log the amount of their food waste for 14 days. We set up five hypotheses before our research.
