Development of a full-cycle water remediation process
Authors: Yerushalmi L. , Seyhi B. 
Published: December 2019

Abstract
A full-cycle water remediation process has been developed by expanding the capacity of an existing water treatment technology that uses combined ozonation and ultrafiltration membrane processes. The developed water reclamation process treated the effluent of a full-scale wastewater treatment plant in Canada that uses biological treatment processes to treat municipal wastewater, and reduced the colour, turbidity, suspended solids, iron and pathogen content of the effluent. The removal of hardness from the wastewater effluent was accomplished by the precipitation process. The use of lime (0.2 g/L) in the presence of NaOH operating at pH 11 showed the best results, reducing the water hardness by 89.1%. The advanced treatment capability of ozonation (8–10% w/w) and polyvinylidene fluoride (PVDF) hollow fiber ultrafiltration (UF) membrane produced a reliable source of water for municipal, industrial and agricultural use. The developed process offers important environmental benefits by reducing the diversion of water from sensitive ecosystems, decreasing wastewater discharge and preventing pollution.

Published: December 2019

Abstract
In this work, titanium dioxide (TiO2) was modified with reduced graphene oxide (rGO), and then coated on filter paper to prepare the rGT/FP photoelectrode for the photoelectrocatalytic (PEC) decolorization of methylene blue (MB). The physicochemical properties of the rGT/FP photoelectrode were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis and UV-Vis diffuse reflectance spectroscopy (DRS). The decolorization results demonstrated that the photocatalytic (PC) and electrocatalytic (EC) efficiency of the photoelectrode could be significantly improved by the modification of rGO. The improvement of PC and EC efficiency might attribute to the existence of rGO, which could extend the light-harvesting efficiency, promote the photocurrent response value and suppress the charge recombination. Furthermore, the PEC decolorization of MB using the rGT/FP photoelectrode presented higher efficiency than the sum of PC and EC decolorization, indicating the synergistic effect between the photo and electrical energy.

Published: December 2019

Background:G protein-coupled receptors (GPCRs) represent the largest family of surface proteins and are involved in the regulation of key physiological processes. GPCRs are characterized by seven transmembrane domains, an extracellular N-terminus and an intracellular C-terminus. Cellular response of these receptors to their ligands is largely determined by their surface expression and postactivation behavior including expression, desensitization and resensitization.Objective:To develop a quantitative fluorescence Microscopy assay to study β2- Adrenergic receptor expression and desensitization.Method:β2-Adrenergic receptor cDNA was engineered to put an HA tag at the extracellular N-terminus and GFP Tag at the intracellular C-terminus. GFP fluorescence serves as a measure of total cellular expression; whereas staining with CY3 conjugated anti-HA antibodies without permeabilizing the cells represents the surface expression of β2-AR. The images are quantified and amount of CY3 (surface) and GFP (total) fluorescence for each cell determined using image processing software.Results:The method is sensitive and allows for the simultaneous measurement of surface and total expression of β2-AR.Conclusion:A highly accurate method is described for measuring β2-AR surface and total expression based on single-cell quantitative immunofluorescence. The method can be used to determine agonist-induced desensitization and resensitization process as well as receptor kinetics like endocytosis and exocytosis of β2-Adrenergic receptor and can be applied to essentially any other GPCR.

Published: December 2019

Aim and Objective:
An efficient and facile DBU catalysed synthesis of highly significant motif
5,7-disubstituted-1,2,4-triazolo[1,5-a]pyrimidines under solvent-free condition has been reported.

Materials and Methods:
To a round bottom flask, 1.0 mmol of chalcone (1), 1.5 mmol of 3-amino-1,2,4-
triazole (2) and 30 mol% of DBU were added at 70 °C and stirred in solvent-free condition. After the
completion of the reaction (monitored by TLC), water (10 ml) was added. The aqueous layer was extracted
with ethyl acetate (3 ×10 ml). The combined organic layers were dried over anhydrous Na2SO4. The combined
organic layers were evaporated under reduced pressure and the resulting crude product was purified by column
chromatography by using ethyl acetate and hexane as eluent.

Results:
Reaction using chalcone and 3-amino-1,2,4-triazole as model substrates were carried out under
different reaction conditions and it was observed that 30 mol% of DBU under the solvent-free condition at
70 °C was the optimum temperature for the proposed synthesis.

Conclusion:
Use of DBU (an organocatalyst) as a base, operational simplicity, high yield of products and short
reaction time are some of the significant advantages associated with the proposed strategy.

Published: December 2019

Background and Objective:
Prostate cancer is the second cause of death in men worldwide. In this
study, the cytotoxic effects of PLGA polymer-coated gold Magnetic Nanoparticles (MGNPs), as a novel treatment
to enhance radiation and thermal sensitivity in the presence of hyperthermia (43°C) and electron beam, on
DU145 prostate cancer cells were investigated.

Methods:
Nanoparticles were characterized using TEM, DLS, XRD and SAED methods. MGNPs entrance into
the cells was determined using Prussian blue staining and TEM. Furthermore, the cytotoxic effects of combinatorial
treatment modalities were assessed by applying colony and sphere formation assay.

Results:
Our results revealed that the decrease of colony and sphere numbers after combinatorial treatment of
hyperthermia and radiation in the presence of nanoparticles was significantly higher than the other treatment
groups (P<0.05). This treatment method proved that it has the capability of eliminating most of the DU145 cells
(80-100%), and increased the value of the linear parameter (α) to 4.86 times.

Conclusion:
According to the study, magnetic gold nanoparticles, in addition to having a high atomic number,
can effectively transmit heat produced inside them to the adjacent regions under hyperthermia, which increases
the effects of radio-thermosensitivity, respectively.

Authors: Iqbal Zahid , Ishaq Muhammad 
Published: December 2019

Abstract
Let k be a positive integer. We compute depth and Stanley depth of the quotient ring of the edge ideal associated to the kth
power of a path on n vertices. We show that both depth and Stanley depth have the same values and can be given in terms of k and n. If n≣0, k + 1, k + 2, . . . , 2k(mod(2k + 1)), then we give values of depth and Stanley depth of the quotient ring of the edge ideal associated to the kth
power of a cycle on n vertices and tight bounds otherwise, in terms of n and k. We also compute lower bounds for the Stanley depth of the edge ideals associated to the kth
power of a path and a cycle and prove a conjecture of Herzog for these ideals.

Monitoring of selected fertilizer nutrients in surface waters and soils of agricultural land in the river valley in Central Poland
Authors: Burzyńska Irena 
Published: December 2019

AbstractThe aim of the study was to assess the content of soluble forms of fertilizer nutrients (N, P, K) in the cultivated soil layer up to 20 cm deep from agricultural land in the river valley, and the concentration of these nutrients in the surface waters of the Raszynka River.In the years 2016–2017, the surface water samples from the Raszynka Rriver (17 points) and soil (19 points) were collected from agricultural areas near the Raszynka River.The surface water samples were collected once a month during the March–October 2016–2017. The contents of nitrogen (Ntot, NO3-N and NH4-N), phosphorus (Ptot, PO4-P), total organic carbon (TOC and K and Ca) in soils and in waters were determined in the sample solutions.It was shown that river water was of low quality due to the high concentration of nitrogen and phosphorus and electrical conductivity (EC). The most polluted were the waters of the lower section of the river located in the vicinity of arable land and agricultural built-up areas. The soluble forms of nutrients content in the cultivated soil layer was varied depending on the kind of nutrient, way of agricultural land use, and the term of soil sampling. The content of dissolved P forms in the soil was the highest in autumn on arable lands after harvesting of vegetables (GO-W: 10.24 mg Ptot·kg−1 in D.M.) and this component may migrate with surface runoff and increase the risk of surface water eutrophication.
Hydrological modeling using the SWAT model based on two types of data from the watershed of Beni Haroun dam, Algeria
Authors: Kateb Zakaria , Bouchelkia Hamid , Benmansour Abdelhalim , Belarbi Fadila 
Published: December 2019

AbstractThe dam of Beni Haroun is the largest in Algeria, and its transfer structures feed seven provinces (wilayas) in the eastern part of Algeria. Due to its importance in the region, it has now become urgent to study its watershed as well as all the parameters that can influence the water and solid intakes that come into the dam. The Soil and Water Assessment Tool (SWAT) model is used to quantify the water yields and identify the vulnerable spots using two scenarios. The first one uses worldwide data (GlobCover and HWSD), and the second one employs remote sensing and digital soil mapping in order to determine the most suitable data to obtain the best results. The SWAT model can be used to reproduce the hydrological cycle within the watershed. Concerning the first scenario, during the calibration period, R2 was found between 0.45 and 0.69, and the Nash–Sutcliffe efficiency (NSE) coefficient was within the interval from 0.63 to 0.80; in the validation period, R2 lied between 0.47 and 0.59, and the NSE coefficient ranged from 0.58 to 0.64. As for the second scenario, during the calibration period, R2 was between 0.60 and 0.66, and the NSE coefficient was between 0.55 and 0.75; however, during the validation period, R2 was in the interval from 0.56 to 0.70, and the NSE coefficient within the range 0.64–0.70. These findings indicate that the data obtained using remote sensing and digital soil mapping provide a better representation of the watershed and give a better hydrological modelling.
Impact study of Beni-Haroun dam on the environmental and socio-economic elements in Kébir-Rhumel basin, Algeria
Authors: Marouf Nadir , Remini Boualem 
Published: December 2019

AbstractSurface water of Kébir Rhumel basin is indispensable for domestic and industrial needs of this region. Industrial development, with water excessive use and chemical products, in production and industrial treatment, and not sustainable fertilizers in agriculture, constitutes a serious threat to maintain our resources of good water quality. The majority of domestic and industrial wastewaters of the region, discharged to the stream water of Kébir Rhumel basin, promote the water enrichment in nutritious elements, phosphorus and nitrogen and particularly, the resulting increase in the aquatic primary production, mainly the planktonic or benthic algae. As a result, the physical and chemical properties of water deteriorate.This basin allows construction of the largest dam in Algeria “Beni-Haroun dam”. The infrastructure that was one of the greatest challenges of Algeria is now a reality. Hydraulic complex of Beni-Haroun remains a strategic and major achievement in the development program of water resources sector. This enormous building was constructed in the territory of the Wilaya (province) of Mila, used to meet water needs, with four million inhabitants, of eastern Algeria and other neighbouring regions that have suffered from lack of water consumption, especially in summer. In addition, it will irrigate over 42 000 ha, going thus to the several plains.Integration of sociological and environmental concerns into dams design is a recent phenomenon. It is considered at the impact study level, during which the dam study project is accompanied by a survey to assess project impact on natural environment and socioeconomic development.
Decision-making models using the Analytical Hierarchy Process in the urgency of land consolidation works
Authors: Oleniacz Grzegorz , Skrzypczak Izabela , Leń Przemysław 
Published: December 2019

AbstractPoland is characterized by a number of factors which adversely affect the agricultural economy, so this paper will aim to present the possibilities of using multi-criteria decision-making methods of Analytical Hierarchy Process (AHP) in the analysis of the spatial structure of rural areas. AHP is a widely used tool for making complex decisions based on a large number of criteria, such as, for example, land consolidation works on fragmented agricultural land. The first step is to formulate the decision-making process, then the assessment criteria and the solution variants guided by expert knowledge are determined.A ranking, according to which the order of land consolidation and land exchange works in the studied area should be determined, will be defined by using decision-making models of the AHP method. The basis for calculations will be the weights received for the factors/parameters defined for the five thematic groups. Calculations for individual villages will be made, and then the obtained results will allow creating a ranking for the studied commune, allowing for the effective (in terms of economic and socio-economic) spending of funds for this purpose. The presented method can be successfully used to conduct analogous analyses for any area.
