The Identification of Fouling in Reverse Osmosis in the Treatment of Water with Petroleum Substances
Authors: Piekutin Janina
Published: April 2021

Water containing petroleum substances is very difficult to clean, and the treatment process usually consists of several stages. Despite the increasing use of integrated membrane processes to purify natural waters, including the removal of organic substances, work is underway on the search for new processes and their optimization. This paper deals with the study of the removal of petroleum hydrocarbons from the benzene, toluene, ethylbenzene, and xylene (BTEX) group by reverse osmosis and optimization. The research was conducted on surface water enriched with a fuel mixture. Then, the reverse osmosis efficiency was modeled using the constant pressure filtration model (Hermia model), which determined the most likely membrane blocking mechanism. When the membrane was operated on surface water enriched with BTEX, the blocking of the membrane was based on the n = 0 cake mechanism. In surface water alone, the highest correlation coefficient was 0.9994 and corresponded to a temporary blocking mechanism (n = 1).

In this study palladium-nickel (Pd-Ni) nanoparticles supported on carbon and cerium oxide (Pd-Ni/AC-CeO2) were synthesized by a transfer phase method and characterized by scanning electronic microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX). The XRD and SEM data concluded the presence of alloy formation between Pd and Ni. The synthesized particles were used as an adsorbent for removal of azo dye acid orange-8 (AO-8) from water and were found to be effective in removal (over 90% removal efficiency) of the selected dye. Different kinetics and equilibrium models were applied to calculate the adsorption parameters. The most suitable model that best fitted the equilibrium data was the Langmuir model and maximum adsorption capacities were 666.6, 714 and 769 mg/g at 293, 313 and 333 K, respectively, with R2 values closed to 1 while in the case of the kinetics data the best fit was obtained with a pseudo-second order kinetics model with a high R2 value. Furthermore, the adsorption thermodynamics parameters such as free energy, enthalpy, and entropy were calculated and the adsorption process was to found be exothermic with a value of ΔH° (−7.593 kJ mol−1), spontaneous as ΔG° values were negative (−18.7327, −19.4870, and −20.584 kJ/mol at 293, 313 and 333 K, respectively). A positive entropy change ΔS° with a value of 0.0384 kJ /mol K indicates increased disorder at the solid–solution interface during the adsorption process. An attempt was made to recycle the Pd-Ni/AC-CeO2 with suitable solvents and the recycled adsorbent was reused for 6 cycles with AO-8 removal efficiency up to 80%. Based on findings of the study, the synthesized adsorbent could effectively be used for the removal of other pollutants from wastewater, however, further studies are needed to prove the mechanisms.

A fast and accurate similarity-constrained subspace clustering algorithm for land cover segmentation
Authors: Hinojosa Carlos , Vera Esteban , Arguello Henry
Published: April 2021

Accurate land cover segmentation of spectral images is challenging and has drawn widespread attention in remote sensing due to its inherent complexity. Although significant efforts have been made for developing a variety of methods, most of them rely on supervised strategies. Subspace clustering methods, such as Sparse Subspace Clustering (SSC), have become a popular tool for unsupervised learning due to their high performance. However, the computational complexity of SSC methods prevents their use on large spectral remotely sensed datasets. Furthermore, since SSC ignores the spatial information in the spectral images, its discrimination capability is limited, hampering the clustering results' spatial homogeneity. To address these two relevant issues, in this paper, we propose a fast algorithm that obtains a sparse representation coefficient matrix by first selecting a small set of pixels that best represent their neighborhood. Then, it performs spatial filtering to enforce the connectivity of neighboring pixels and uses fast spectral clustering to get the final segmentation. Extensive simulations with our method demonstrate its effectiveness in land cover segmentation, obtaining remarkable high clustering performance compared with state-of-the-art SSC-based algorithms and even novel unsupervised-deep-learning-based methods. Besides, the proposed method is up to three orders of magnitude faster than SSC when clustering more than 2x104 spectral pixels.

Background: The economic impact associated with the treatment strategies of coronavirus disease-2019 (COVID-19) patients by hospitals and health-care systems in Brazil is unknown and difficult to estimate. This research describes the investments made to absorb the demand for treatment and the changes in occupation rates and billing in Brazilian hospitals. Methods: This research covers the initial findings of “COVID-19 hospital costs and the proposition of a bundled reimbursement strategy for the health-care system,” which includes 10 hospitals. The chief financial officer, the chief medical officer, and hospital executives of each participating hospital provided information regarding investments attributed to COVID-19 patient treatment. The analysis included variations in occupation rates and billing from 2019 to 2020 observed in each institution, and the investments for medical equipment, individual protection materials and building construction per patient treated. Results: The majority of hospitals registered a decrease in hospitalization rates and revenue from 2019 to 2020. For intensive care units (ICUs), the mean occupancy rate ranged from 88% to 83%, and for wards, it ranged from 85% to 73%. Monthly average revenue decreased by 10%. The mean hospital investment per COVID-19 inpatient was I$6800 (standard deviation 7664), with the purchase of ventilators as the most common investment. For this item, the mean, highest and lowest acquisition cost per ventilator were, respectively, I$31 468, I$48 881 and I$17 777. Conclusion: There was significant variability in acquisition costs and investments by institution for responding to the COVID-19 pandemic. These findings highlight the importance of continuing microeconomic studies for a comprehensive assessment of hospital costs. Only with more detailed analyses, will it be possible to define and drive sustainable strategies to manage and reimburse COVID-19 treatment in health-care systems.

Issues related to the disabled right in the country continue to attract criticism and debate, as implementation is very slow and weak. The disabled have the right to live like other normal people, which includes protection in times of danger and emergency. One of the important mechanism for the care of the disabled is through legal means. The government has signed the United Nations Convention on the Rights of Persons with Disabilities (CRPD) as part of its efforts to empower and protect this minority group. As such, the government has taken the initiative to enact the Persons with Disabilities Act 2008 and ratified the Convention on the Rights of Persons with Disabilities (CRPD) in 2010 as one of the government’s commitments in complying with international human rights conventions as long these do not against the Federal Constitution. This article aims to uncover and analyse the legal provisions in Malaysia relating to the disabled and their right to live, as stated in the Federal Constitution and relevant legal provisions. In essence, this shows that Malaysia, as a member of the UN, is bound to adopt international laws and treaties on human rights if these do not violate local norms and values. At the end of the discussion, some ideas are presented as solutions for the government to improve the issue of disabled persons so that in the eyes of the world, Malaysia will be recognized as one of the countries that cares for and defends its disabled, in line with the Convention on the Rights of Persons with Disabilities 2008.

This nonrandomized, multicenter cohort, open-label clinical trial evaluated the efficacy and safety of combined chemotherapy with arsenic trioxide (ATO) in children with stage 4/M neuroblastoma (NB). We enrolled patients who were newly diagnosed with NB and assessed as stage 4/M and received either traditional chemotherapy or ATO combined with chemotherapy according to their own wishes. Twenty-two patients were enrolled in the trial group (ATO combined with chemotherapy), and 13 patients were enrolled in the control group (traditional chemotherapy). Objective response rate (ORR) at 4 weeks after completing induction chemotherapy was defined as the main outcome, and adverse events were monitored and graded in the meantime. Data cutoff date was December 31, 2019. Finally, we found that patients who received ATO combined with chemotherapy had a significantly higher response rate than those who were treated with traditional chemotherapy (ORR: 86.36% vs. 46.16%,p=0.020). Reversible cardiotoxicity was just observed in three patients who were treated with ATO, and no other differential adverse events were observed between the two groups. ATO combined with chemotherapy can significantly improve end-induction response in high-risk NB, and our novel regimen is well tolerated in pediatric patients. These results highlight the superiority of chemotherapy with ATO, which creates new opportunity for prolonging survival. In addition, this treatment protocol minimizes therapeutic costs compared with anti-GD2 therapy, MIBG, and proton therapy and can decrease the burden to families and society. However, we also need to evaluate more cases to consolidate our conclusion.

Microorganisms, particularly bacteria, are considered to play a role in the etiology of certain corneal infectionsobserved during soft contact lens wear. This study explored the possibility of microbial colonization of softcontact lenses as a risk factor leading to corneal infection. In a clinical trial conducted and 86 lenses wererecovered aseptically and analyzed for microbial colonization. The incidence of bacteria and fungi wasfewer during corneal infection than during asymptomatic lens wear. During asymptomatic lens wear, cornealinfection bacteria were isolated most frequently and were usually normal external ocular microbiota. Of theGram-positive bacteria, the incidence of Staphylococcus aureus was fewer during asymptomatic wear. WhileGram-negative bacteria were seen in high cases during asymptomatic wear, this includes Escherichia coliand Pseudomonas aeruginosa. Fungal screening and identification revealed 2 cases of contamination withthe yeast Candida albicans that able to form a biofilm. Colonization of soft contact lenses with pathogenicbacteria, especially gram-negative and gram-positive bacteria, appears to be a significant risk factor leadingto corneal infection.

Published: April 2021

The present study focused on screening of biosurfactants produced by Leu-conostoc strains isolated from dromedary milk with antimicrobial and antiad-hesive properties against various pathogenic microorganisms and its poten-tial application in medical fields as an antibiofilm agent. After identification of the selected strains by mass spectrometry, screening methods for biosur-factants production were used, including drop collapse, oil displacement, surface tension and emulsification index. Antiadhesive assays were carried out against six pathogenic microorganisms in polystyrene surface, and ap-plied on rubber silicone tubes. Four lactic acid bacteria were isolated and identified as Leuconostoc sp according to MALDITOF MS spectrometry. Bio-surfactants isolated from Leuconostoc strains reduced tension surface from 72.0 to 45.7 by strain BY14, with an emulsification efficiency (E24) after 24h of 63%. The crude biosurfactants were effective against most pathogenic microorganisms with inhibition percentage from 92.3% to 44.3% after adhe-sion to polystyrene. Otherwise, the antiadhesive activity displayed values from 75.67% to 13.2%. The result of application test demonstrated that the selected crude biosurfactants reduced significantly all the deposited microbi-al biofilm from rubber silicone tubes. This study suggest that biosurfactants could have a promising role as an effective antibiofilm to prevent microbial colonization on medical devices.

The symbiotic association of alfalfa (Medigaco sativa) with Sinorhizobium melilloti contributes to the production of inoculum to improve plant growth and increase yield. The competitiveness of the introduced strains is a very important factor in the performance of an inoculum which is based on the use of rhizobial strains. This competitiveness is due to the production of anti-microbial substances, among them, bacteriocines. In this study, the totals of 30 rhizobial strains were isolated from M. sativa nodules sampled from sa-line soils of Algeria. Twenty strains were nodulated the host plant M. sativa. The antimicrobial activity producing strains SW16 and SW15 were identified as Sinorhizobium melliloti based on 16S rRNA sequance analysis. Partial puri-fication of this inhibitorys substances by ammonium sulfate were precipitat-ed with 75% saturation. These antimicrobial activitys showed the maximum activity against the strain SW10 estimated at 1800 with the strain SW16 and 2500 AU/ml for the strain SW15. The physicochemical properties of these antimicrobial activitys reveals thier thermoresistant nature and sensitive to protease, but theire were resistant to a wide range of pH and also at differ-ent concentrations of Nacl. This inhibitory agent display primary metabolite kinetics as its maximal production was detected in the growth phase. Antimi-crobial substances produced by sinorhizobium mielilloti SW15 and SW16 exhibited inhibitory activity against the phytopathogen (Aspergillus sp., Fusarium sp., Cladosporium sp. and Alternaria altterna).

Antimicrobial resistance, especially in Escherichia coli, represents one of the most important human and animal health-threatening issues worldwide. The aim of this study was the characterization and the comparison of Antimicro-bial drug resistance of Escherichia coli strains isolated from urinary tract in-fection (UTI) and food (raw beef meat) in Oum El Bouaghi city-Algeria. The determination of antibiotics susceptibility pattern was realized by using the agar disk diffusion method, according to the recommendations of the French Society for Microbiology (FSM, 2019). A total, 159 E. coli were obtained from both clinical and food samples, with a frequency of isolation of 100% from raw beef meat and 59% from UTI. ESBL phenotype was detected only in 17% of clinical isolates. Also, the results of this work reveal that there is a highly significant difference in antibiotic resistance between clinical and foodborne isolates except for gentamicin. This high prevalence is a warning sign to adopt new control policies to prevent the further spread of this antimicrobial resistance.

The aphid Chaitophorus leucomelas (Koch, 1854) is one of the most im-portant pests of poplar (Populus spp.) in Algeria. In the present study, water content in leaves and phytochemical analysis of two poplar species (P. nigra and P. deltoids) were carried out to assess their trophic impact on life-history traits of C. leucomelas. The study was conducted in two areas located north of Algeria during the period printano-summer. The results showed that each metabolite fluctuated at the expense of physiological variations in the plant depending on its reaction to the study area. Soluble carbohydrates gradually decreased over the two study seasons. The concentration of proline was higher for P. deltoids in Zeralda comparing to Soumâa. However, the flavo-noids showed close values. Interestingly, Relative water content and soluble carbohydrates had a positive effect on both aphid weight and lipidic ener-getic reserves on P. nigra, but on P. deltoids only carbohydrate content was marginally related to soluble carbohydrates.
Study for salt tolerance using CAPS markers in key DNA regulation se-quences in durum wheat (Triticum turgidum L. var. durum) as new alternative
Authors: Mohammed Saadallah
Published: April 2021

In arid and semi-arid regions, particularly around the Mediterranean basin, soil salinization is one of the abiotic factors that reduces the agricultural yield of several crops and especially the cereal species. Molecular genetics, as an alternative method, makes it possible to select eligible plants for desi-rable traits at an earlier age. Selection based on markers such as CAPS (cleaved amplified polymorphic sequence) can lead to increased accuracy and selection responses in plants. A simple method for detecting polymor-phism of the WRKY candidate gene was performed on nine varieties of du-rum wheat (Triticum turgidum L. var. durum) for the identification of tolerant varieties. The DNA was amplified with a pair of primers, and digested with a restriction endonuclease that recognizes the SNP sequence. The electropho-retic analysis revealed the amplification of 7 bands of different sizes per pro-file in all individuals tested. The analysis of profiles after digestion shows that out of a total of seven bands, five bands do not change size. While, the two fast bands of 130 and 144 bp disappear and two other bands of 122 and 118 bp appear only after digestion, in all individuals studied. In our work, we were unable to demonstrate restriction variation in the DNA binding domain sequences of the transcription factor WRKY1, On the other hand, we show that the CAPS technique can be an easily used alternative, for the detection of variation in key DNA sequences, such as those of the transcription factor binding domains or their cis-acting elements sequences.

The fibers of the date palm (FP) offer a real alternative for the development of a bio composite constituting the horticultural substrate (HS). It is, environ-mentally friendly and preferable in terms of cost, availability and water ab-sorption capacity compared to commercial peat. In this work, using the soil-less crop, we studied the main physicochemical characteristics of 3 HS and the witness (WT) composed by peat. These HS were composed by 3 different rates of PF and topsoil (TS) in proportions (PF% -TV %): T(80-20), T(70-30) and T(60-40). The growth parameters of Vitro plant (VT) of potatoes (Solanum tuberosum) grown in these HS were also studied. The T(80-20) gave the most appropriate physicochemical parameters and the most suita-ble parameters for normal growth plant compared to the other substrates. The T(80-20) irrigated by the nutrient solution (NS) composed by (g / L): 0.38, 0.48 and 0.48 for N, P, K respectively gave the best evolution of the EC-pH couple during the whole plant cycle compared to the others NS studied. This couple did not exceed the stressful values of 3 mS for EC and 7 for pH. This same HS gave, also, the best yields and fruit number (FN).
AIRLINE PILOT SITUATION AWARENESS: PRESENTING A CONCEPTUAL MODEL FOR META-COGNITION, REFLECTION AND EDUCATION
Authors: Irwin William , Kelly Terrence
Published: April 2021

The dissertation research summarized here, utilized the Grounded Theory Method to develop a conceptual model of pilot situation awareness from 223 Aviation Safety Reporting System (ASRS) narratives. The application of Latent Semantic Analysis aided the theoretical sampling of ASRS reports. A multistage model was developed involving attention, perception, interpretation, decision making, and action in support of goal-driven behavior. Narrative report coding identified several categories of situation awareness elements that pilots direct their attention to in building and maintaining situation awareness. Internal to the aircraft, flight crews directed their attention to the aircraft’s flight state and automation state. They also directed their attention to the condition of the aircraft, the functioning of the crew, and the status of the cabin. External to the aircraft, flight crews directed their attention to airport conditions, air traffic control, terrain, traffic, and weather. Pilots were also aware of the passage of time. Twelve characteristics of situation awareness were identified from narrative report coding which were subsequently compared with existing theoretical perspectives of situation awareness.

Published: April 2021

Project management in the construction sector is a complex and uncertain process and companies tend to look for the lowest value in the procurement of services and materials. However, contractors do not share the necessary information with the contracted parties and thus give rise to the asymmetric information (AI) phenomenon. The aim of this study is to perform an analysis of the determining factors in the adoption of relational contracting (RC) in combination with Building Information Modelling (BIM) to reduce AI. The results of a questionnaire survey, which was e-mailed to 14 specialists with solid experience (over twenty years) and knowledge in construction projects, revealed that the probability of the AI phenomenon occurring in Portugal is very high, and its impact on construction projects is equally high. The results also show that RC in combination with the BIM methodology contributes very positively to the mitigation of AI problems in construction projects in Portugal. Approximately 85% of respondents consider that the government should seek to reduce AI in the public works sector through the use of RC and its combination with the BIM methodology in the Portuguese Public Contracts Code.

Authors: Haza Marion , Moutte Jean-Philippe
Published: April 2021

Les auteurs envisagent l’engagement de certains adolescents dans la lutte contre les mutations écosystémiques et leur nécessaire reconnaissance par les adultes comme l’expression d’un travail psychique de démocratisation. La situation de Jonathan, adolescent tourmenté élevant des fourmis, illustre une modalité de rencontre possible avec l’environnement non humain, source de gratification tant pour le narcissisme que pour les idéaux, mais révélant une angoisse d’extinction prononcée.
