Abstract
Background: Although plant molluscicides are biodegradable and less toxic to higher animals, unregulated applications could affect other non target aquatic species. Eco toxicological studies are required to evaluate whether they are safe to those economically and ecologically important fish species. According to previous studies, Achyranthes aspera is a molluscicidal plant with LC90 of 96.5 mg/L and the current study is to investigate its toxic effect to Nile tilapia fish fingerlings, Oreochromis niloticus. Methods: Seven fish fingerlings were exposed to serial dilutions of A. aspera leaf aqueous extract for 96 hours in duplicate setup. Phytoconstituents were identified by GC-MS and lethal concentrations were determined by probit model. The NOAEC was determined by hypothesis testing on the survival data. Results: The respective piscicidal LC1, LC10 and LC50 values were 897.4, 1063.9 and 1310.74 mg/L. The NOAEC was 1100 mg/L (p>0.05). GC-MS analysis revealed 12 phytoconstituents including a monoterpene. Conclusion: The result shows that A. aspera is non toxic and hence is safe to Nile tilapia fish especially at its molluscicidal dose limit (96.5 mg/L LC90) corroborating to the plant’s target specific molluscicidal potential.

Published: April 2021

Abstract
In this study we have demonstrated an integrated approach for utilization of microalga Scenedesmus sp, generated during CO2 sequestration, in fabrication of catalytic and antimicrobial silver nanoparticles composite. The algal biomass was grown in open raceway pond of 30,000 L scale for CO2 sequestration, after which it was harvested and dried. The dried biomass served as a reducing and immobilizing agent for silver nanoparticles. The biomass-silver nanoparticles composite was used for the first time, as a heterogenous catalyst for reduction of a prominent industrial pollutant, p-Nitrophenol, in aqueous medium under ambient condition. Series of experiments were conducted to evaluate the effect of calcination temperature, load and reuse of the material on its catalytic efficiency. The calcined composite material was found to be an excellent catalyst for reduction of p-Nitrophenol. As low as 5 mg mL− 1 calcined material could catalyse the reduction of more than 95% p-Nitrophenol at the rate of 0.60 mg L− 1 min − 1 in aqueous solution at 10 ppm concentration. The efficiency of catalysis was evaluated for ten cycles of reuse. The material was found to be a potential candidate as a reusable heterogenous catalyst for designing continuous flow system for remediation of industrial effluents rich in p-Nitrophenol. Furthermore the material served as a good antimicrobial agent against pathogenic bacteria and fungi. Two strains each of gram + ve and gram –ve bacteria and three strains of fungi were used in the antimicrobial studies using well diffusion method.

A qualitative exploration of pharmacovigilance policy implementation in Jordan, Oman, and Kuwait using Matland's ambiguity-conflict model
Authors: Garashi Hamza Y. , Steinke Douglas T. , Schafheutle Ellen I. 
Published: April 2021

Abstract
Background

As Arab countries seek to implement the 'Guideline on Good Pharmacovigilance Practice (GVP) for Arab countries', understanding policy implementation mechanisms and the factors impacting it can inform best implementation practice. This study aimed to explore the mechanisms of and factors influencing pharmacovigilance policy implementation in Arab countries with more established pharmacovigilance systems (Jordan, Oman), to inform policy implementation in a country with a nascent pharmacovigilance system (Kuwait).
Results

Matland's ambiguity-conflict model served to frame data analysis from 55 face-to-face interviews which showed that policy ambiguity and conflict were low in Jordan and Oman suggesting an "administrative implementation" pathway. In Kuwait, policy ambiguity was high while sentiments about policy conflict were varied suggesting a mixture between "experimental implementation" and “political implementation”. Factors reducing policy ambiguity in Jordan and Oman included: decision-makers' guidance to implementors, stakeholder involvement in the policy's development and implementation, training of policy implementors throughout the implementation process, clearly outlined policy goals and means, and presence of a strategic implementation plan with appropriate timelines as well as a monitoring mechanism. In contrast, policy ambiguity in Kuwait stemmed from the absence or lack of attention to these factors. Factors reducing policy conflict included: the policy's compliance with internationally recognised standards and the policy's fit with local capabilities (all three countries), decision-makers' cooperation with and support of the national centre as well as stakeholders' agreement on policy goals and means (Jordan and Oman), and adopting a stepwise approach to implementation (Jordan).
Conclusion

Using Matland’s model, both the mechanism of and factors impacting successful pharmacovigilance policy implementation were identified. This informed recommendations for best implementation practice in Arab as well as other countries with nascent pharmacovigilance systems including increased managerial engagement and support, greater stakeholder involvement in policy development and implementation, and undertaking more detailed implementation planning.

Published: April 2021

Abstract
In this paper, the design and development of dual-band and triple-band fractal microstrip patch antennas with enhanced gain are presented. The structure is based on the Sierpinski carpet fractal, where the multiband functionality is achieved by applying the fractal iteration technique. The fractal antenna characteristics along with analysis of the reflection coefficient and the radiation patterns for each iteration are presented. The dual-band fractal microstrip patch antenna (DBFMPA) is operating at 4.9 and 5.3 GHz and the triple-band fractal microstrip patch antenna (TBFMPA) is operating at 2.4, 5.3, and 5.9 GHz. The defected ground structure (DGS) and a reflector plane is utilized for enhancing the gain of the antenna. Design and optimization of the DBFMPA and TBFMPA are done using the Computer Simulation Technology (CST) Microwave Studio Suite. The presented DBFMPA and TBFMPA are suitable for industrial, scientific, and medical (ISM) wireless applications.
Force-Sensitive Mat for Vertical Jump Measurement to Assess Lower Limb Strength: Validity and Reliability Study
Authors: Vanegas Erik , Salazar Yolocuauhtli , Igual Raúl , Plaza Inmaculada 
Published: April 2021

Background
Vertical jump height is widely used in health care and sports fields to assess muscle strength and power from lower limb muscle groups. Different approaches have been proposed for vertical jump height measurement. Some commonly used approaches need no sensor at all; however, these methods tend to overestimate the height reached by the subjects. There are also novel systems using different kind of sensors like force-sensitive resistors, capacitive sensors, and inertial measurement units, among others, to achieve more accurate measurements.

Objective
The objective of this study is twofold. The first objective is to validate the functioning of a developed low-cost system able to measure vertical jump height. The second objective is to assess the effects on obtained measurements when the sampling frequency of the system is modified.

Methods
The system developed in this study consists of a matrix of force-sensitive resistor sensors embedded in a mat with electronics that allow a full scan of the mat. This mat detects pressure exerted on it. The system calculates the jump height by using the flight-time formula, and the result is sent through Bluetooth to any mobile device or PC. Two different experiments were performed. In the first experiment, a total of 38 volunteers participated with the objective of validating the performance of the system against a high-speed camera used as reference (120 fps). In the second experiment, a total of 15 volunteers participated. Raw data were obtained in order to assess the effects of different sampling frequencies on the performance of the system with the same reference device. Different sampling frequencies were obtained by performing offline downsampling of the raw data. In both experiments, countermovement jump and countermovement jump with arm swing techniques were performed.

Results
In the first experiment an overall mean relative error (MRE) of 1.98% and a mean absolute error of 0.38 cm were obtained. Bland-Altman and correlation analyses were performed, obtaining a coefficient of determination equal to R2=.996. In the second experiment, sampling frequencies of 200 Hz, 100 Hz, and 66.6 Hz show similar performance with MRE below 3%. Slower sampling frequencies show an exponential increase in MRE. On both experiments, when dividing jump trials in different heights reached, a decrease in MRE with higher height trials suggests that the precision of the proposed system increases as height reached increases.

Conclusions
In the first experiment, we concluded that results between the proposed system and the reference are systematically the same. In the second experiment, the relevance of a sufficiently high sampling frequency is emphasized, especially for jump trials whose height is below 10 cm. For trials with heights above 30 cm, MRE decreases in general for all sampling frequencies, suggesting that at higher heights reached, the impact of high sampling frequencies is lesser.
The games of imitation: AI and a philosophy towards future equilibrium
Authors: Barry Todd J. 
Published: April 2021

This brief conceptual article starts with an argument for Artificial Intelligence (AI)’s ability to “think.” This outgrowth relates to human’s and AI’s power over nature, and to AI’s increasing power in its humanness, measured by the results of competing with humans and other AI machines in the Turing Test, and economic “game theory.” Both, and especially the latter challenge, can be quintessentially human by measuring how one values the self as opposed to society, under varying conditions. Given AI’s advancements enabling it to presumably “win” in the most humanness of games, beyond even reaching a universally beneficial “social optimal” outcome, and thus possibly even having more power than humankind, the article argues for an equilibrium of balanced powers in innovation between AI and humans. Therefore, managers, broadly construed, can function as key brokers between government policy makers and innovators as AI and humans continue to develop further into the future.

Published: April 2021

Location and routing are the main critical problems investigated in a logistic. Location-Routing Problem (LRP) involves determining the location of facilities and vehicle routes to supply customer's demands. Determination of depots as distribution centers is one of the problems in LRP. In LRP, carbon emissions need to be considered because these problems cause global warming and climate change. In this paper, a new mathematical model for LRP considering CO2 emissions minimization is proposed. This study developed a new Mixed Integer Linear Programming (MILP) model for LRP with time windows and considered the environmental impacts. Finally, a case study was conducted in the province of Central Java, Indonesia. In this case study, there are three depot candidates. The study results indicated that using this method in existing conditions and constraints provides a more optimal solution than the company's actual route. A sensitivity analysis was also carried out in this case study.

Published: April 2021

Every code in the latest study of group ring codes is a submodule thathas a generator. Study reveals that each of these binary group ring codes can havemultiple generators that have diverse algebraic properties. However, idempotentgenerators get the most attention as codes with an idempotent generator are easierto determine its minimal distance. We have fully identify all idempotents in everybinary cyclic group ring algebraically using basis idempotents. However, the conceptof basis idempotent constrained the exibilities of extending our work into the studyof identication of idempotents in non-cyclic groups. In this paper, we extend theconcept of basis idempotent into idempotent that has a generator, called a generatedidempotent. We show that every idempotent in an abelian group ring is either agenerated idempotent or a nite sum of generated idempotents. Lastly, we show away to identify all idempotents in every binary abelian group ring algebraically by fully obtain the support of each generated idempotent.

Abstract
Human cumulus cells (CCs) play a key role in the regulation of ovarian follicle maturation and oocyte fertilization. They influence the oocyte development by transferring the various molecules via the specific gap junction proteins, also known as the connexins, which provide a direct transmembrane connection between the oocyte and CCs. The human CCs were obtained in the patients diagnosed with infertility, who underwent the procedure of the controlled ovarian stimulation, and the following in vitro fertilization to elucidate the possible involvement of the CCs in the regulation of the fertilization and oocyte aging. Collected samples were long-term cultured and harvested after 7, 15, and 30 days of cultivation. Afterward, we assessed the relative expression of the following apoptosis regulatory genes - BAX, CASP9, and TP53 - using the RT-qPCR method. We noted a decrease in the expression of all above-mentioned genes in the samples harvested after 15 and 30 days, in reference to 7 days in vitro cultured CCs. In summary, our results provide precious insight into the dynamics of changes and confirm the continuous expression of the proapoptotic genes – BAX, CASP9, and TP53 in the long-term cultured CCs.
