Abstract
Seismic waves which are formed during an earthquake carries enormous force that transfers to the base of the structures in different directions. Due to this, the building structure undergoes drastic changes in existing stresses and strains. Mechanisms that are responsible for the damages in structures during an earthquake are acceleration of floors and inter story drift. The traditional ways of resisting the foresaid force are shear walls, moment resisting frames and braced frames etc. It is documented frequently that; the traditional methods are not completely effective to absorb the earthquake force. Therefore, Seismic isolation concept is an effective rehabilitation strategy that is in practice now and gives favorable results. In this work, 6 x 3 Bay with 14 Stories (G +13) RCC building structure incorporated with Lead Rubber Bearing (flexible base isolation) and fixed base have been modeled and analyzed for earthquake force along with other active forces using FEM program. The structural quantities, time history investigations and response spectrum examinations have been compared for both base isolation and fixed base models. It is found that the technique adopted decreases the seismic response considerably compared to conventional (fixed base) structures which intern controls the damages in building. Bases shear and floor accelerations have been reduced but displacements increased in isolated base when compared with fixed base.

Abstract
The Cadmium sulfide (CdS) is the most advantageous material for the manufacture of the elaborate solar cells in thin layers, the study that we present, will relate to the elaborated and the characterization of CdS thin film deposited on glass substrates by chemical bath deposition (CBD) method. This study will help us to know if the annealing atmosphere nature affects the deposition of thin films of CdS. The X-ray diffraction (XRD) analysis reveals that the structures of pure thin films are Hexagonal and polycrystalline with preferential orientation (002). The scanning electron microscopy (SEM) measurements showed that the surface morphology homogeneous and uniform. The energy dispersive X-ray analysis (EDAX) studies confirmed that the films are nearly stoichiometric. The transmittance in the visible region (200-800 nm) is high of 60%, and band gap values oscillated between 2.36 and 2.47 eV for al thin films.

Published: July 2021

Abstract
Combination therapy including anticancer drugs usually induces synergistic effects, especially in combination with natural compounds as a chemical sensitizer. Nano-based drug delivery technology is also effective in solving the toxicity of single drugs at high doses. In this study, we established a co-delivery strategy for abemaciclib (ABE) combined with vitamin E succinate (VES) based on HA-modified calcium phosphate (CaP) nanomaterials to enhance anti-cancer effect. The nano-sized HA/CaP particles (90 nm) have a hollow structure. Surprisingly, after modification with HA, HA/CaP has more pH sensitivity. CaP released 30% ABE and 91% VES at pH 7.4, whereas HA/CaP vsreleased 14% ABE and 32% VES at the same pH. Cell experiments showed that HA/CaP/ABE-VES had stronger cell inhibitory effect on MCF-7 compared with CaP/ABE-VES. This inorganic/organic composite for the co-delivery of ABE and VES has obvious tumor inhibition effect, and is ideal for anti-tumor drug delivery.
A Frequency-based Parent Selection for Reducing the Effect of Evaluation Time Bias in Asynchronous Parallel Multi-objective Evolutionary Algorithms
Authors: Harada Tomohiro 
Published: July 2021

Abstract
This paper proposes a new parent selection method for reducing the effect of evaluation time bias in asynchronous parallel evolutionary algorithms (APEAs). APEAs have the advantage of increasing the computational efficiency even when the evaluation times of solutions differ. However, APEAs have a problem that their search direction is biased toward the search region with a short evaluation time. The proposed parent selection method considers the search frequency of solutions to reduce such an adverse influence of APEAs while maintaining their computational efficiency. We conduct experiments on toy problems that reproduce the evaluation time bias on multi-objective optimization problems to investigate the effectiveness of the proposed method. The experiments use NSGA-III, a well-known multi-objective evolutionary algorithm. In the experiments, we compare the proposed method with the synchronous and the asynchronous methods. The experimental results reveal that the proposed method can reduce the effect of the evaluation time bias while reducing the computing time of the parallel NSGA-III.

This paper provides a review of the applications of some graphene oxide-based hydrogels in bone tissue engineering. Hydrogels used in bone tissue engineering usually require suitable biocompatibility, porosity, and mechanical strength. Under the original hydrogel condition, by adding GO, the various indexes of the composite hydrogel can reach more suitable conditions for inducing bone defect healing. This article also introduces some high-performance graphene oxide-based hydrogels, which are likely to play an important role in bone tissue engineering in the future.

Organocatalysis: An Overview of its Application in Oxidation and Reduction
Reactions
Authors: Mukhopadhyay Chhanda , Pal Rammyani 
Published: July 2021

:
Organocatalysis was established to be a wide-applicable approach from its inception and
rediscovery in the year 2000, where proline was used as a catalyst in aldol condensation and soon
after the successful emergence of iminium catalysed reactions in organic synthesis. Development
of new potential catalytic systems is always an important as well as an uphill task for scientists and
researchers. The fundamental organic synthesis majorly deals with metal based catalysts, whereas
there is a constant surge of developing metal free reaction condition to make the reactions environmental
friendly. For the synthesis of complex organic molecules, reduction and oxidation reactions
are always needed and there are plenty of catalysts available for these reactions. Organocatalysts
are also developed and applied for these two elementary reactions. This review focuses on some of
the latest developments and applications of organocatalysts in oxidation and reduction reactions in
fundamental organic synthesis.

A Funky-Formal Fashion Collection: Struggling for a Creative Concept in HUGO BOSS
Authors: Tang Vangkilde Kasper 
Published: July 2021

In this case study, we follow a group of five young talented fashion designers in HUGO BOSS charged with creating a new concept for the brand BOSS Orange. The concept is to be neither formal nor funky but, precisely, funky-formal. Based on ethnographic fieldwork among these designers, the case describes in detail how the initial idea of a funky-formal fashion collection gradually grows into a more concrete creative concept for such a collection. In particular, it shows how the designers struggle to get to know the HUGO BOSS brands, to become truly inspired, to generate a compelling concept and, finally, to make a decision between competing concepts. These processes involve not just the talented designers but also, and not least, the Creative Director of BOSS Orange, making it evident how creativity in fashion is by no means an individual idiosyncrasy but rather a social phenomenon.
The Towards Silence Project: Multiple String Quartets Organize to Perform a New Musical Form in Spatially Variable and Distributed Conditions
Authors: O'Donnell Shannon 
Published: July 2021

This case describes an example of a collective making process in the field of performing arts. In 2009, multiple string quartets (many considered world class) organized to perform a new musical composition by Sir John Tavener. The composition challenged four quartets at a time to perform as an integrated ensemble while sitting apart, in various configurations, and at spatial distances up to 70 feet. The process unfolded in three phases: pre-rehearsals of the first group of quartets in the United Kingdom (UK), a series of rehearsals leading to one premiere performance by the second group of quartets in New York, and a series of rehearsals integrated with additional performances in four distinct venues in the UK. Mid-way through the process, the musicians chose to integrate a simple coordinating technology into their process, to address the difficulties produced by distance. This telling of the case story describes what the musicians did to achieve these unprecedented performances, given the unusual circumstances, emphasizing how they made decisions and evaluated their work along the way. The case is based on comprehensive fieldwork, including observation, interviews, spatial measurement and diagramming, questionnaires, and analysis of videotape of the rehearsal process.

Una muestra de la arquitectura moderna en Tunja: la obra del arquitecto Ernesto Muñoz Navarro. Una historia nunca contada
Authors: Pinilla Marcela , Toro Ospina Alexandra , Melo Vera Diana 
Published: July 2021

La vida diaria de la ciudad de Tunja, Boyacá, Colombia es testigo desde hace más de medio siglo de la arquitectura moderna; sin embargo, este estilo arquitectónico ha sido objeto de muy pocos estudios, tal vez debido a la preminente importancia que tiene para el habitante tunjano y para la academia, la imagen e identidad de Tunja como ciudad colonial, que, por tanto, prima sobre la imagen moderna de ciudad y sus manifestaciones arquitectónicas.
Este artículo recopila conclusiones preliminares y el avance de la investigación realizada sobre la vida y obra del Arquitecto e Ingeniero Ernesto Muñoz Navarro, pionero de la aplicación de los conceptos del modernismo en Tunja.
Los datos obtenidos nos acercan a la figura de Ernesto Muñoz Navarro y lo ubican en un momento clave del desarrollo del país en el cual la arquitectura moderna fue protagonista. Adicionalmente, el presente artículo hace una reflexión sobre la falta de reconocimiento del valor patrimonial de la arquitectura moderna, que es justamente lo que ha llevado a que la obra de Ernesto Muñoz Navarro sea totalmente desconocida.
Para iniciar el trabajo, se consideró fundamental realizar la investigación sobre la vida de este personaje, como aspecto fundamental para poder entender y apreciar su obra. Posteriormente, se indagó sobre el momento histórico en el cual el profesional del arte de la construcción Ernesto Muñoz Navarro construyó en Tunja edificaciones que marcaron el desarrollo de la ciudad. Un resumen de estas dos etapas del trabajo de investigación se consigna en este artículo, el cual brinda una reflexión sobre el valor que tiene la arquitectura moderna en la ciudad de Tunja y la necesidad de rescatar dicho valor desde la apropiación ciudadana y la investigación académica.
Comparative Study of the Parallel and Angular Electrical Gripper for Industrial Applications
Authors: Fotuhi Mohammad Javad , Bingul Zafer 
Published: July 2021

Abstract
The aim of this paper is to study the position and power performances of an electrical lead screw-driven industrial gripper mechanism (LSDIGM). This work consists of designing and developing an electrical LSDIGM that has the potential to meet various demands in the automation industry and factories. The performances of both angular electrical gripper (AEG) and parallel electrical gripper (PEG) mechanisms were compared based on their position and power efficiency. The position efficiency of these electrical LSDIGM is computed from the position root mean square error (PRMSE) obtained from errors between the two measured positions (input incremental encoder and output linear encoder). In the experimental setup, a current sensor and a spring were employed to measure the current in the input of the system and the stiffness in the output of the system, respectively. The electrical power in the input of the electrical LSDIGM and the mechanical power in the output of the LSDIGMs were calculated using the current and the spring force, respectively. Finally, the power efficiency of these electrical LSDIGMs was examined and compared at different velocity circumstances.
Approximate Formulation of the Rigid Body Motions of an Elastic Rectangle Under Sliding Boundary Conditions
Authors: Şahin Onur , Erbaş Barış , Wilson Brent 
Published: July 2021

Abstract
Low-frequency analysis of in-plane motion of an elastic rectangle subject to end loadings together with sliding boundary conditions is considered. A perturbation scheme is employed to analyze the dynamic response of the elastic rectangle revealing nonhomogeneous boundary-value problems for harmonic and biharmonic equations corresponding to leading and next order expansions, respectively. The solution of the biharmonic equation obtained by the separation of variables, a consequence of sliding boundary conditions, gives an asymptotic correction to the rigid body motion of the rectangle. The derived explicit approximate formulae are tested for different kinds of end loadings together with numerical examples demonstrating the comparison against the exact solutions.
Birds Strike – Impact on the Safety of Civil Aircraft Operations in Poland in 2008–2018
Authors: Balicki Włodzimierz , Glowacki Paweł , Loroch Leszek 
Published: July 2021

Abstract
The authors assessed the real threat to civil aircraft traffic in Poland resulting from bird strikes. It was found that in the period 2013–2018, the probability of such events increased by four times. Data for this work were downloaded from the ECCAIRS database maintained by the Civil Aviation Authority. Air traffic events have been collected for several years in this database. An assessment of the energy of bird collision with the aircraft, resulting from the bird’s mass and relative speed of movement, was also presented. Ways to minimise the risk of collision were described by introducing crew warning systems and means to scare off birds from the airport grounds. The method of testing the resistance of turbine engines to the foreign body’s absorption was also shown, as well as design methods for increasing the engine resistance to bird strikes.
Preliminary hydrochemical characteristics of an urban lake restored using a sequential application of iron and aluminum coagulants
Authors: Płachta Anna 
Published: July 2021

Abstract
A study was carried out on Lake Mielenko in Kartuzy. It is a small and shallow waterbody (7.8 ha, max. depth 1.8 m), whose morphometric conditions qualify it as a polymictic lake (the first lake in a river - lake system). Before the reclamation began, the lake was characterized by a high concentration of chlorophyll-a (16.4 mg m−3 in spring to 33 mg m−3 in summer) and low visibility. The purpose of the study was to determine the impact of the first stage of restoration of Lake Mielenko by phosphorus inactivation using a combination of aluminum and iron coagulants (PIX and PAX). After coagulant dosing into the lake, a significant decrease in chlorophyll-a was observed, which resulted in improving water transparency in the lake and decreasing concentrations of both nutrients (nitrogen and phosphorus). The total concentration of nutrients was dominated by organic forms (constituting 71-95%). Maximum nutrient concentrations were 0.273±0.01 mg P L−1 and 5.52±0.1 mg N L-1 (in the summer period before the restoration activities were performed).
Were there any changes in zooplankton communities due to the limitation of restoration treatments?

Published: July 2021

Abstract
Zooplankton is a good indicator of water quality state. Analysing the species composition and abundance, it is possible to assess the condition of the water body and predict the direction of changes. The aim of the study was to analyse the zooplankton in a shallow urban lake, in which restoration was limited to one method, i.e. wind-aeration. The results were compared with the earlier data obtained during sustainable restoration (three methods: wind-aeration, phosphorus inactivation, biomanipulation) and before the restoration period. The zooplankton was sampled monthly in 2015 and 2016 in the deepest place of the lake from the surface to the bottom. The trophic state was determined based on rotifer trophic state index for lakes (TSIROT). Although the species composition of zooplankton communities varied very little among the restoration periods (Keratella cochlearis f. tecta mainly dominated), significant changes in the abundance of zooplankton were found in the analysed lake. The maximum of total abundance was noted in 2015, almost 5500 ind. L−1, and in the next year its decrease was almost 3-fold, to ca. 1800 ind. L-1. Based on TSIROT, the water was still eutrophic. Leaving only one method of restoration (namely, oxygenation of the bottom waters) proved insufficient to support the development of crucial organisms as cladocerans. The changes in the abundance could have resulted more from seasonal changes than from the effects of aeration. A reduction in species number and maintaining a high proportion of rotifers typical for a high trophic state indicated a return of the ecosystem to its pre-restoration state. High variability in the rotifer abundance indicated a continuous imbalance of the ecosystem. Previous restoration treatments using several methods simultaneously showed better effectiveness. The change of strategy of restoration before obtaining a stable improvement of water quality destroyed previously achieved effects.
