Published: June 2021

Abstract
Resource Planning Optimization (RPO) is a common task that many companies need to face to obtain several benefits, like budget improvements and run-time analyses. It is often addressed by using several software products and tools, based on sophisticated mathematical artifacts. However, these tools are not able to provide a practical solution because they are often expensive and time-consuming. On the other hand, Artificial Intelligence-based approaches have been increasingly used in many industrial and scientific fields in last decades, and have demonstrated to be a valid alternative to the classical mathematical-based methods. For this purpose, the following paper aims to investigate the use of multiple Artificial Neural Networks (ANNs) for solving a RPO problem related to the scheduling of different Combined Heat & Power (CHP) generators. The experimental results, carried out by using data extracted by considering a real Microgrid system, have confirmed the effectiveness of the proposed approach. Additionally, we show that multiple neural networks achieve up to a 6% improvement in average accuracy over Naive Bayes classifier, up to a 12% over Multi-Layer Perceptron classifier and up to a 13% over state-of-the-art ANNs in the presence of unbalanced training dataset.

Abstract
Usage of wastewater to irrigate crops increases in Egypt and the whole world as a result of water shortage. This study is conducted to explore the potential of Abelmoschus esculentus Moench. (Okra plant) to accumulate and translocate eight trace metals: lead: Pb, cadmium: Cd, chromium: Cr, copper: Cu, iron: Fe, manganese: Mn, nickel: Ni and zinc: Zn in its different tissues due to irrigation with untreated industrial wastewater. It extended to assess the effect of the irrigation with wastewater on the growth parameters, nutrients, pigments and organic contents of the cultivated okra plants.Two studied sites at South of Cairo was conducted, the first site (29°42'31.17" N and 31°15'11.56" E); represented by five cultivated fields irrigated with Nile water (control) and the second site (29°42'37.87" N and 31°17'14.53" E); fields irrigated with effluent receive untreated industrial wastewater. Three composite soil and irrigated water samples were collected from each site. A significant decrease in nutrients: nitrogen (N), Potassium (K) and Phosphorous (P) in soil and Plants were resulted due to irrigation with wastewater. Also, there was a significant increase in trace metals concentration in both soil and plants irrigated with wastewater. A significant decrement in okra growth parameters and leaves photosynthetic pigments (chlorophyll a and b and carotenoids) due to irrigation with wastewater. Iron was the highest accumulated metal in the plant's fruits (edible part) irrigated with wastewater. Also, the concentration of Cd, Cu, Fe, Mn, Ni and Zn (42.57, 140,67, 2756.67, 1293.33, 1326.67 and 877.83 mg kg− 1, respectively) was in the phytotoxic range. Wastewater irrigated okras accumulate all of the studied trace metals in their roots (Bioaccumulation factor: BF > 1). In contrast, okra plants had no accumulated trace metals strategy in their shoot, as translocation factor values were less than one. Authors recommended avoiding consuming okra plants cultivated in fields irrigated with wastewater due to high trace metals concentration in their edible part.

Abstract
Objective Cancer stem cells (CSCs) play an important role in tumor development. Some studies have demonstrated that P-element–induced wimpy testis (Piwi)–interacting ribonucleic acids (piRNAs) participate in the progression of various cancers. However, the detailed function of piRNAs in CSCs requires further investigation. The aim of the present study was to investigate the effect of the uknown upregulated piRNA MW557525 and its predicted target gene nucleolar protein 56 (NOP56) inPiwi-like protein 2 (Piwil2)–induced CSCs (Piwil2-iCSCs).Methods We screened differential piRNAs of Piwil2-iCSCs using high-throughput sequencing (HTS). Target genes were predicted by the miRanda algorithm and subjected to Gene Ontology (GO) analysis. One of the differential piRNAs, MW557525, and its target gene NOP56 were transfected and silenced in Piwil2-iCSCs, respectively. Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to detect expression levels of piRNA MW557525 and NOP56 in Piwil2-iCSCs after transfection. We measured protein levels of NOP56 in different groups via Western blot (WB), verified interactions using a dual luciferase reporter assay (LRA) and investigated the effect of piRNA MW557525 and NOP56 on Piwil2-iCSC proliferation using a Cell Counting Kit-8 (CCK-8). In addition, we evaluated cell migratory and invasive abilities via transwell assay and detected cell apoptotic ability via flow cytometry (FCM) assay. Protein levels of Cluster of Differentiation 24 (CD24), CD133, Krüppel-like factor 4 (KLF4) and sex-determining region Y–related high-mobility group (HMG) box 12 (SOX2) were measured to evaluate the change in Piwil2-iCSC pluripotency after transfection.Results Via HTS, we screened out 204 differential piRNAs, and miRanda predicted 77 target genes. GO analysis showed that the biological processes (BPs) of these target genes were mainly involved in regulating the calcium concentration of cells and their molecular functions (MFs) were mainly involved in ATPase activity.The expression of piRNA MW557525 and NOP56 were significantly upregulated,and piRNA MW557525 was negatively associated with NOP56 in Piwil2-iCSCs. PiRNA MW557525 promoted proliferation, migration, invasion and pluripotency and inhibited apoptosis, while NOP56 suppressed proliferation, migration, invasion and pluripotency and induced apoptosis, in Piwil2-iCSCs.Conclusion Taken together, these findings suggested that piRNA MW557525 promoted and maintained the vitality and pluripotency of Piwil2-iCSCs, while NOP56 inhibited these characteristics. Therefore, piRNA MW557525 might be a novel therapeutic target in Piwil2-iCSCs.
Design and Simulation of High-performance Planar npp+ Heterojunction CH3NH3PbI3 Based Perovskite Solar Cells Using BaSnO3 ETM and Cu2O HTM
Authors: Rahman Atowar 
Published: June 2021

Abstract
In recent years, organic-inorganic hybrid perovskite solar cells (PSCs) have received more and more attention due to their high photovoltaic (PV) performance, potentially high efficiency, simple cost-effective, scalable, and vacuum-free fabrication techniques. Concerned, but there are still stability issues in PSCs. The use of inorganic materials as photogenerated carrier transport layers can enhance the stability of PSC. In this report, we designed a PSC model with a novel npp+ heterojunction cell structure of Al/ITO/BaSnO3 /CH3NH3 PbI3 /Cu2O/(Cu or Mo) and analyzed the structure by varying the thickness and carrier concentration of each constituent layer, working temperature, and back-contact metal work function using SCAPS-1D solar cell simulator. The simulation addresses, in particular, the role of the BaSnO3 as electron transport materials (ETM) and Cu2O as hole transport materials (HTM) for the device performance. Using BaSnO3 and Cu2O as ETM and HTM, respectively, this article presents the optimization of cell parameters to improve device performance with a predicted power conversion efficiency (PCE) of 32% for the modeled PSC. The proposed novel structure for PSC showed very good PV performance stability on elevated temperature with the temperature coefficient of PCE of only - 0.112 %K-1.

Abstract
Background

Several studies have highlighted the difficulties faced by caregivers of patients with brain tumors. We created the educational workshops called AGAPE. Their aim is to explain precisely the medical aspects of brain tumors, describe resources available, and allow a moment of exchange between caregivers.
Purpose
To evaluate outcomes of AGAPE.
Methods

This was an observational uncontrolled pilot study. Feasibility was evaluated by the caregivers’ attendance of the 2 theoretical scheduled sessions and their satisfaction. Additional outcomes were the percentage of caregivers in favour of AGAPE sustainability and the impact on their quality of life according to CarGOQoL questionnaires (Caregiver Oncology Quality of Life) between baseline before the first workshop and after the last one.
Results

From February 2015 to March 2019, 12 three-month sessions were organized allowing 87 caregivers to participate. 84% of caregivers attended at least 2 theoretical sessions, the level of satisfaction was very high, and all caregivers were in favor of AGAPE sustainability. 36 caregivers submitted completed questionnaires at baseline and after the last workshop attended, separated by more than 2 months. The first workshop took place mostly during or after the adjuvant treatment of their loved ones. Two-thirds of their loved ones had a progressive disease after the first workshop and 21 died. Caregivers’ quality of life was stable between the first and last attended workshop.
Conclusion

Our study showed that AGAPE helped to maintain caregiver’s quality of life despite patient’s disease progression and its feasibility. Moreover, AGAPE may easily be run in other hospitals.

Published: June 2021

Abstract
In this study, a self-made wire-cylinder dielectric barrier discharge (DBD) reactor was used to remove NOx. The influence of electrical and gas parameters (e.g. structure, voltage, and frequency) and temperature on the NOx removal rate was studied systematically while operating the DBD reactor with a high-voltage positive–negative double pulse power supply. The experimental results showed that following conditions led to the optimal NO conversion rate and NOx removal rate: voltage of ±12 kV, pulse frequency up to 60 Hz, oxygen concentration at 6%, reaction temperature at 300°C, and C2H2:NOx ratio at 1.5. Under these conditions, the NO conversion rate and NOx removal rate reached the highest levels of 76.4% and 31.2%, respectively. Additionally, when the process was run in conjunction with a La0.7 Sr0.3 Ni0.5 Mn0.2 Fe0.3 O3 catalyst, the reactor efficiency increased markedly, and the NO conversion and NOx removal rates increased to 94.93% and 74.97%, respectively. The findings of this study demonstrate that DBD reactor technology shows promise for the removal of NOx from automotive waste streams.

Authors: Vanarelli Mark J. 
Published: June 2021

Abstract
The construction of underground excavations and tunnels can only be done safely and economically when the subsurface conditions are adequately understood. Excessive groundwater inflows into rock tunnels under construction can injury personnel and terminate the construction of the tunnel project. Therefore, it is important to accurately estimate groundwater inflows into rock tunnels. A semi-empirical procedure/method for estimating steady-state, groundwater inflows in shallow rock tunnels is presented and discussed in this paper. In addition, this paper presents two case study analyses which include the Elizabethtown tunnel in New Jersey and the Toledo tunnel in Ohio. Packer test (i.e., pressure test) data was analyzed for both case studies utilizing this semi-empirical procedure. This paper reviews the theory behind the procedure, summarizes validates the procedure through case study analyses. It also describes previous proposed modifications and clarifies the need for any such modifications. In general, good groundwater inflow estimates were derived for shallow rock tunnels utilizing this semi-empirical procedure/method.

Abstract
Green supply chain management (GSCM) is an important part of most production organisations in developed countries. Meanwhile, developing countries are yet to fully embrace the concept. This study, therefore, investigated the drivers of GSCM using a close-up approach in a leading manufacturing organisation in Nigeria with sustainability initiatives. One hundred and fifty-four questionnaires retrieved from the supply chain management team of the organisation were subjected to descriptive and inferential statistics such as mean score, standard deviation, and factor analysis. Based on the results of the analyses, that the drivers of GSCM in the organisation could be grouped as government-related, organisational-related, and societal-related drivers. The study concluded that synergy of the government, organisations, non-government organisations, and individual is important for achieving green supply chain practices in developing countries. It was recommended that training at all levels is essential to improve the awareness and importance of sustainable production to the environment.

Published: June 2021

Abstract
Heavy metal resistant siderophore-producing bacteria (SPB) with plant growth promoting traits can assist in phytoremediation of heavy metal contaminated soil. We isolated siderophore producing bacteria from lead and zinc mine soil in Shangyu, Zhejiang, China. The isolate with highest siderophore production, strain SX9, was identified as Burkholderia sp. The strain SX9 produced catecholate type siderophore, with highest production at a pH range 6.0 to 8.0, a temperature range 20 to 30 °C and NaCl concentration below 2%. Siderophore production was highest without Fe3+ and became gradually lower with increasing Fe3+ concentration. Minimal inhibitory concentrations (MIC) of Pb2+, Zn2+, Cu2+ and Cd2+ were 4000, 22000, 5000 and 2000 μmol·L-1, respectively. The strain SX9 was sensitive to doxycycline hyclate and rifampicin. The strain had a strong metal solubilization ability: the contents of Cu2+, Zn2+ and Cd2+ in the supernatant were 47.4%, 133.0% and 35.4% higher, respectively, in the strain SX9 inoculated cultures than in the not inoculated controls. The siderophore produced by strain SX9 could combine with Fe3+, Zn2+ and Cd2+ with good effectiveness. The plant growth promoting traits of the strain included indole acetic acid (IAA) production, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity and phosphate solubilization capability. Compared to uninoculated growth medium and SX9 culture supernatant, the germination rate of Lolium perenne seeds was higher when inoculated with the strain SX9 culture. In the experiment of seed germination, adding bacterial culture or supernatant could alleviate the toxicity of heavy metals to Lolium perenne seed germination. Under Cu2+ and Zn2+ stress, the strain SX9 promoted the germination rate. Taken together, the strain SX9 had properties beneficial in the microbial enhancement of phytoremediation of soil contaminated with heavy metals.

Abstract
PurposeIn our previous study,we found a rare type of medication-related osteonecrosis of the jaw (MRONJ), which shows periosteal reaction (PR) at a site distant from the osteolytic lesions or extraction site (periosteal reaction dominant type: PRd type), even though the osteolytic lesions in the bone marrow are localized. Given that the causes and treatment of MRONJ remain unclear, this study aimed to describe the imaging and clinical features of the PRd type.MethodsPatients with MRONJ who visited Nagasaki University Hospital during 2009-2020 and received conservative therapy as the initial treatment were included in this study. Site of PR, imaging findings, initial symptoms, outcome, and time to progression were examined.ResultsOf the 59 MRONJ patients treated with conservative therapy, 38 did not show PR (PR- type), 15 showed PR near the osteolytic region (PR+ type), and six had the PRd type. All patients with the PRd type had submental abscesses, and computed tomography (CT) images demonstrated PR on the lingual side of the anterior mandible. Osteolytic lesions progressed in 6/6 PRd type (100%), 5/15 PR+ type (33.3%), and 2/38 PR- type (5.3%) patients. Time to progression for the osteolytic region on CT was short for the PRd type, at 56-148 days (median, 79 days).ConclusionAmong the MRONJ types, the PRd type has a poor prognosis. Therefore, it is necessary to accumulate and analyze more PRd cases in the future. This is the first report to report the presence of this specific subtype of MRONJ,
Insights into Bioindicator Redundancy for Monitoring Water Quality based on Functional Units of Periphytic Protozoan Communities in Marine Ecosystems

Published: June 2021

Abstract
Although periphytic protozoan communities have long been used for the bioassessment of water quality, their utility is hampered by functional redundancy leading to high “signal to noise” ratios. In this study, a 1-year baseline survey of periphytic protozoan communities was carried out in coastal waters of Yellow sea, northern China, in order to determine redundancy levels in conditions of differing water quality. Samples were collected at four sampling sites along a pollution gradient. Environmental variables such as salinity, chemical oxygen demand (COD), and concentrations of dissolved oxygen (DO), soluble reactive phosphates (SRP), ammonium nitrogen (NH4-N) and nitrate nitrogen (NO3-N) were measured to compare with biotic factors. A total of 53 functional units (FUs) were identified from 144 observed protozoan species based on four biological traits, i.e., feeding type, body size, movement type and source of food supply. For reducing the “signal to noise” ratios of species-abundance/biomass data, the peeling procedure was used to identify the bioindicator redundancy levels based on these FUs. Three consecutive subsets of response units (RU1–RU3) with correlation coefficients >0.75 of the full FU dataset were identified, comprising 12, 21 and 9 FUs, respectively. Algivores and bacterivores were dominant in RU1 and RU2 among the polluted sites, whereas raptors were dominant in RU3 at the unpolluted site. In terms of relative abundance, RU1 was the primary contributor to the protozoan communities during the 1-year cycle and its relative abundance increased with increasing pollution, whereas RU2 and RU3, with complementary temporal distributions, generally decreased with increasing pollution. Ordinations based on boot-strapped average analyses revealed a significant variation in functional pattern of all three RUs among the four sampling sites. Biological-environmental match analysis demonstrated that the variability was driven by the increasing concentrations of nutrients (e.g., NH4-N, NO3-N and PO4-P) and decreasing concentrations of DO (P<0.05). Based on these findings, it is suggested that there were high levels of functional redundancy among periphytic protozoan communities used as bioindicators of marine water quality.
Fuzzy Rule Based Video Watermarking in DWT-SVD Domain
Authors: S Ponni alias sathya , S Ramakrishnan 
Published: June 2021

Abstract
This paper addresses the issues in video copyright using DWT and SVD. The prevailing algorithms countermeasure various attacks and they do not contemplate on the redundancy of frames in the video. Proposed methodology focuses on the identification of non-redundant frames by introducing a fuzzy model for reducing the processing time. The frequently changed scenes are identified by scene change detection algorithm. The key frames are effectively identified from each scene by fuzzy rules using entropy, absolute mean difference and absolute difference of frame variance of the video frames. DWT is applied to the key frames. The watermark image is divided into number of blocks based on the number of key frames selected in the scene. The order of embedding the watermark block in each scene is different. The SVD is applied to the key frames and watermark. In the embedding process, the singular values of key frame are added to the Principal Component (PC) of the watermark bock. The experimental results show that the proposed methodology is resilient to image processing, frame based attacks and also resolves the false positive problem as well as improves the robustness and imperceptibility of video and watermark.

Abstract
The study of loading rate of microorganisms in the space of hospital inside and outside to evaluate their impacts on physical health of patients and staff, as well as to find out the source of possible infections and allergies stemming from the presence of bioaerosols is of great importance. In total, 262 bacterial and fungal samples were collected from the air of the wards of Tohid Hospital, Sanandaj, Iran. Also, suspended particles were measured by Particle Mass Counter (model: TES-5200). Parameter such as relative humidity and temperature were recorded by using TES-5200 device. To identify bacteria, some biochemical and molecular tests were conducted. And, for the identification of fungi, microscopic and macroscopic characteristics were used. The highest and lowest densities of the bioaerosols were observed in lung and operating wards (336.67 and 15.25 CFU/m3). Moreover, the highest and least concentrations of particles were seen in the emergency and operating wards, respectively. The most common fungi isolated from the hospital air were Penicillium (24.7%), Cladosporium (23. 4%), Aspergillus niger (13.3%) and Aspergillus Flavus (11.4%). Furthermore, the highest concentration of the isolated bacterium was Staphylococcus hemolyticus (31.84%). And, the bacteria had the most resistance to antibiotic gentamicin.The general average of air pollution of the hospital to bioaerosols in quantitative terms was higher than that suggested by international organizations. Considering the high concentration of bioaerosols and particles in the hospital studied, provision of optimal conditions (like temperature, humidity, suitable ventilation and intelligent air conditioning system) and imposing a restriction in the entrance of the wards can be utilized to reduce the amount of pollution.
