Finding a relationship between physicochemical characteristics and ionic composition of River Nworie, Imo State, Nigeria
Authors: Verla Evelyn Ngozi , Verla Andrew Wirnkor , Enyoh Christian Ebere 
Published: February 2020

Water has been described as a universal solvent, and this is perhaps the strength behind its many uses. Despite this unique property, anthropogenic activities along its course and natural factors often determine the composition of water. In the current research, the portion of River Nworie having past Owerri town was sampled in the dry season 2017 to determine its ionic composition at predestinated points and to relate such properties to its physicochemical characteristics. Studies relating physicochemical properties and dissolved toxic ions in water could develop a body of knowledge that could enable detection and quantification of potential risk of ions such as heavy metals from natural water to aquatic ecosystem, animal and human health without actually involving aquatic organism, animal and human. Clean sterile plastic bottles were used for collecting surface water. A total of 30 sub-samples from five points at 300 m apart were sampled in the morning. Physicochemical properties were determined using standard methods and ionic composition of water was determined according methods of APHA. Results revealed that Ca2+ had a mean 23.60 ± 0.67 mg/l and was the highest while K+ with a mean 0.72 ± 0.30 was the least amongst major cations. Amongst the major anions Cl− had mean of 31.58 ± 4.47 mg/l while mean of PO43− was 1.42 ± 0.13 mg/l. The ionic balance calculate as % balance error showed high values for all sampling sites ranging from 30 to 39.42% indicating that there is massive input from anthropogenic activities. The computed relationships for selected heavy metals, cations and anions revealed that R2 values were ranging between ± 0.012 to 1 indicating some form of relationship existing. The water pH weakly correlated with dissolved cations and anions while moderate with pH only, due to the pH level (5.2–6.2). The cations and anions were more influenced by the water temperature than the heavy metals. Therefore, high temperature ranges of 31–32.4 °C will favour more dissolution of cations and anions in natural water. Cations showed stronger relationship with EC while only heavy metals showed no relationship with DO (Dissolved oxygen). Dissolved oxygen relationship with cations and anions was in the order; K+ > Mg2+ > Ca2+ > Na+ while anions was SO42− > NO3− > Cl− > PO43−, respectively. Information here could be used to predict the effects of using this water for various purposes including water for agricultural purposes, in the management of ion polluted waters, and also to inform on the mitigation process to be taken.

Published: February 2020

AbstractAs an important member of group VA–VIA semiconductors, 2D Sb2Se3 has drawn widespread attention thanks to its outstanding optoelectronic properties as compared to the bulk material. However, due to the intrinsic chain‐like crystal structure, the controllable synthesis of ultrathin 2D planar Sb2Se3 nanostructures still remains a huge challenge. Herein, for the first time, the crystal structure limitation is overcome and the successful structural evolution of 2D ultrathin Sb2Se3 flakes (as thin as 1.3 nm), by introducing a sodium‐mediated chemical vapor deposition (CVD) growth method, is realized. The formation of 2D planar geometry is mainly attributed to the preferential growth of (010) plane with the lowest formation energy. The thickness‐dependent band structure of 2D Sb2Se3 flakes shows a wide absorption band from UV to NIR region (300–1000 nm), suggesting its potential application in broadband photodetection. Strikingly, the Sb2Se3 flakes–based photodetector demonstrates excellent performance such as broadband response varying from UV to NIR region, high responsivity of 4320 mA W−1, fast response time (τrise ≈ 13.16 ms and τdecay ≈ 9.61 ms), and strong anisotropic ratio of 2.5@ 532 nm, implying promising potential application in optoelectronics.

Published: February 2020

AbstractA palladium‐catalyzed intramolecular α‐arylation and defluorinative aromatization strategy for the synthesis of polysubstituted 2‐naphthols is reported. With ortho‐bromobenzyl‐substituted α‐fluoroketones as the substrates and palladium acetate/triphenylphosphine as the catalyst, this method features good functional group tolerance, readily available catalyst and starting materials, and high yields. The applications of the strategy are demonstrated by the synthesis of useful building blocks, such as naphtha[2,3‐b]furan, naphthol AS‐D, and ligands/catalysts.magnified image
Precision double cropping synergistically improves wheat and maize yields as well as resource efficiency

Published: February 2020

AbstractClimate variability has resulted in mismatches between recommended and optimum seeding rates, sowing and harvest dates, fertilizer application, and irrigation levels in North China Plain double cropped systems. The objective of this study was to compare traditional local double‐crop practices (LP) with high‐yield double‐cropped treatments (HY) and precision double‐cropped managements (PM). The LP treatment follows local practices, whereas HY optimizes yield regardless of cost, and PM optimizes economic returns by adjusting the planting and harvest dates, and the seeding and fertilizing rates. The average production cost for LP, HY, and PM was 3775, 4824, and 4218 USD ha−1, respectively, and the average income was 5882, 6892, and 6622 USD ha−1. The annual yield for the PM was 3.9% lower, and the annual profit was 16.2% higher than those for HY. The annual yield for the PM was 11.8% higher, and the annual profit was 11.0% higher than those for the LP. Unlike LP, HY and PM transferred 1.19–2.52% of the redundant effective accumulated temperature and the cumulative solar radiation received during the wheat (Triticum aestivum L.) season to the maize (Zea mays L.) season. This increased the production efficiency attributed to temperature and light energy by 12.86–17.48%. In addition, PM obtained the greatest N use efficiency among all treatments. These results show that PM is the appropriate approach to simultaneously increase yields, resource efficiency, and profit. The findings can be used to provide a scientific basis for double‐crop wheat and maize systems featuring high yield and high efficiency.
Distributed production: Scale‐up vs experience
Authors: Patience Gregory S. , Boffito Daria C. 
Published: February 2020

AbstractConcepts such as process intensification, distributed manufacturing, and modularity are becoming mainstream as the chemical industry has to meet the demand for growth while concurrently facing sustainable development challenges. To meet economies of scales, modularity appeals to the concept of numbering up (scaling down and then scaling out). As numbering up becomes more common and a necessity, investors look at solid financial predictors to reduce the uncertainty around the fate of their assets. Traditional economic models that either scale up or scale down the investment for a plant size with a power law (exponent α) of a reference unit at a given capacity (Q) and its investment (I) are valid for the several identical plants and their components. When it comes to scaling down and then numbering up, the investment, or rather price of a modular plant the exponent relating price and capacity is β = 1/n − 1. We report a case study to scale down a 1000 barrel/day (bbl/day) micro‐refinery gas‐to‐liquid unit to convert wasted natural gas to Fischer‐Tropsch fuels. The investment for 100 units 100 times smaller approaches the cost of the same production capacity given by a single 1000 bbl/day unit costing $1 million.
Historical DNA as a tool to genetically characterize the Mediterranean sand tiger shark (Carcharias taurus, Lamniformes: Odontaspididae): A species probably disappeared from this basin

Abstract

The sand tiger shark (Carcharias taurus) is a coastal species distributed in temperate and sub‐tropical waters, classified as ‘Vulnerable’ at global level and ‘Critically endangered’ in eastern Australia, south‐western Atlantic Ocean, and Mediterranean Sea. Six populations (north‐western Atlantic, Brazil, South Africa, Japan, eastern Australia, and western Australia) with low genetic diversity and limited gene flow were identified worldwide, but genetic information for many other geographic areas are still missing. Specifically, this species is listed in several reports as part of the Mediterranean fauna, even if there has been a lack of catches and sightings in recent years in this basin. To clarify the origin of C. taurus individuals caught in the past in the Mediterranean Sea, historical samples were genetically analysed.
Nine samples with certain Mediterranean origin were collected from different European museums. DNA was extracted and ~600 bp of the mitochondrial DNA control region were amplified using eight overlapping species‐specific primer pairs. Sequences obtained were aligned with all the haplotypes globally known so far.
Genetic analysis revealed the misidentification of one museum specimen. Among the remaining Mediterranean historical samples, three different haplotypes were recovered. Two of them previously observed only in South Africa and one described in both South African and Brazilian populations.
Results suggest a genetic relationship between Mediterranean sand tiger sharks and those from the western Indian Ocean. According to previous studies, we hypothesized that, during the Pleistocene, the cold Benguela upwelling barrier was temporarily reduced allowing the passage of C. taurus individuals from the Indian to Atlantic Ocean. After the restoration of this phylogeographic barrier some individuals were trapped in the Atlantic Ocean and probably migrated northward colonizing the western African coasts and the Mediterranean Sea.
A study of [O III]/[O II] lines ratio in type 1 active galactic nucleus: Influence of radio jets and Eddington ratio to narrow line region emission

Published: February 2020

AbstractWe analyze emission line properties and their correlations for 18,043 type 1 active galactic nucleus (AGN) in the range of 0.02 ≤ z ≤ 0.8, based on Sloan Digital Sky Survey Data Release 14 data. We complement the data with photometric measurements from ROSAT, GALEX, 2MASS, and FIRST. We find the following: (a) The average correlation between luminosity of [O III] and AGN luminosity is stronger than those for [O II] line. This is consistent with the stratified model of narrow line region (NLR). Furthermore, we also find a weak dependence of ionization degree with AGN luminosity. (b) The narrow lines luminosity and radio luminosity correlation is stronger for radio quiet AGN and weaker for radio loud (RL) AGN, most likely due to radio jets. A possible explanation is as the jets penetrate the NLR, the shock will ionize its gas, increase the narrow lines emission, and cause a bigger dispersion in the correlation for RL AGN. (c) The investigated narrow lines, [O II], [O III], Hβ, Hα, [N II], and [S II], show a significant trend of decreasing luminosity ratio relative to the broad Hβ luminosity where the slopes in the range of −0.26 to −0.50. We did not find any correlation of the trend slopes with ionization potential or critical density of the lines. We suggest that this correlation is due to decrease in covering factor of NLR as AGN luminosity increases. (d) The EV1 correlation is found in our data and represents change in Eddington ratio. By using L[O III]/L[O II] ratio, we found that the ionization degree decreases as Eddington ratio increases. We also confirm that objects with higher Eddington ratio tend to have narrower Hβ, stronger Fe II emission, and weaker [O III] strength. In contrast to that, objects with lower Eddington ratio tend to have broader Hβ, weaker Fe II emission, and higher [O III] strength.

Authors: Cardoni Andrea , Kiseleva Evgeniia , Lombardi Rosa 
Published: February 2020

AbstractOur paper investigates the integration of anticorruption practices, corporate strategy and business processes of contemporary organisations to provide a new and emerging sustainable governance model. Using the single case study approach to answer our research question, we provide novel evidence from the analysis of the Italian manufacturing company Acciai Speciali Terni Spa. Our case study interprets a consolidated entrepreneurial experience, constructing an integrated meta‐management framework of anticorruption practices. Enriching existing literature, we have adopted the frameworks by Asif et al., (2010) and Asif et al., (2011) to test results and obtain general perspectives and practical implications for organisations, regulators and governments, proposing a sustainable governance model to prevent corruption and bribery.

AbstractBackgroundEpidermal growth factor receptor (EGFR) is overexpressed in head and neck squamous cell carcinomas (HNSCCs). Midkine expression is restricted in adult tissues but is increased in several malignant tumors, including HNSCCs.AimHere, we evaluated the antitumor effect of Midkine promoter–based conditionally replicative adenovirus expressing siRNA against EGFR for targeting HNSCCs expressing Midkine.Methods and resultsA conditionally replicative adenovirus vector controlled by the Midkine promoter, Ad‐MK‐siEGFR, was generated by integrating gene‐expressing siRNA against EGFR. Antitumor effect of Ad‐MK‐siEGFR was tested in vitro using established HNSCC cell line, T891 with strong Midkine expression. Expression of EGFR in T891 infected with Ad‐MK‐siEGFR was significantly lower than that of T891 infected with control. Cytotoxicity assays showed significant growth suppression of Ad‐MK‐siEGFR in T891 cells.ConclusionsThis study demonstrated the possibility of oncolytic therapy using the Midkine promoter–based conditional replication‐selective adenovirus containing siRNA against EGFR in HNSCC cell line T891. Further validation of the findings in more cell lines and in vivo should be performed to clarify the potential clinical application.
Synthesis of 2′‐Deoxyuridine Modified with a 3,5‐Difluoro‐4‐Methoxybenzylidene Imidazolinone Derivative for Incorporation into Oligonucleotide Probes for Detection of HER2 Breast Cancer Marker

Published: February 2020

AbstractNucleoside intercalator conjugates (NICs) describe an innovative methodology developed in our research group for preparation of fluorescence turn‐on DNA hybridization probes targeting specific mRNA sequences (e.g., breast cancer markers). In this methodology, we conjugate a non‐fluorescent intercalator to the base of a nucleic acid (e.g., uracil) via a flexible spacer. This modified monomer can be incorporated into oligonucleotides by solid‐phase synthesis and a large fluorescence enhancement is observed when the modified oligonucleotide is hybridized with its complementary strand due to intercalation of the fluorophore between the two strands. 5‐(6‐p‐Methoxybenzylidene imidazolinone‐1‐hexene)‐2′‐deoxyuridine (dUMBI) is a synthetic monomer to which 4‐methoxybenzylidene imidazolinone (MBI), the fluorescent chromophore of green fluorescent protein (GFP), has been conjugated via a flexible spacer. The detection of human epidermal growth factor receptor 2 (HER2) mRNA by this probe has already been established by our group. The fluorescent intensity of the single‐strand DNA can be considered as negligible due to the free rotation of the fluorophore. Upon hybridization, however, the flexible spacer allows for the intercalation of the fluorophore between the hybridized strands, giving rise to enhanced fluorescence and indicating the presence of target mRNA. 3,5‐Difluoro‐4‐methoxybenzylidene (DFMBI) has enhanced photophysical properties compared to MBI fluorophore. This protocol describes a simple, reliable, efficient, and general method for the synthesis of improved derivative dUDFMBI as a monomer of fluorescent turn‐on DNA hybridization probe with application for detection of HER2 mRNA. © 2020 by John Wiley & Sons, Inc.Basic Protocol: Synthesis of 5‐[(6)‐3,5‐difluoro‐4‐methoxybenzylidene imidazolinone‐1‐hexene]‐2′‐deoxyuridine
