Published: January 2020

The low nutrient availability rainfall patterns regimes are the main constraints to agricultural production in Niger. This was a study of the decomposition and mineralization of nutrients of four types of composts (M1P, M2P, M1H and M2H) in a sandy soil. It was carried out at the experimental N'Dounga station (CERRA Kollo) located about 15 km from Niamey. A randomized blocks design with five repetitions was used. For the evaluation of yield, two doses (1 t ha-1 and 1.5 t ha-1) were applied per millet. Decomposition and mineralization were assessed after burial at 10 cm depth between of a small bag containing 100 g (five small bags / compost). The characterization of the physico-chemical elements of composts samples after incubation has shown that composts are rich in nutrients. Nitrogen ranged from 0.8% to 1.1%, phosphorus from 9.99 mg.kg-1 to 12.76 mg.kg-1 and potassium from 19.94 cmolc dm-3 to 26.26 cmolc dm-3. All four composts are basic (pH> 7). Compost M2H lost more than 80% of its weight during the 10 weeks of the experiment compared to 48% for the M1P. the mineralization of N, P and K is greater at compost M1P (83.6% N, 72.72% P and 89.5% K). This compost also gave the highest yield (1272.5 kg ha-1). The decomposition and mineralization of the main elements (N, P and K) allow the synchronization between the release of nutrients from these composts and the nutrient requirements of millet in a sandy soil.

Conclusion: This study showed that a larger percentage of clinicians, claimed awareness of Art therapy being used as an adjunctive tool in patient care, and believes in its therapeutic benefits. Lack of facilities was identified as an obstacle to the use of art therapy in patient care.
Associations between the Wellbeing Process and Academic Outcomes
Authors: P. Smith Andrew , L. Firman Kirsty 
Published: January 2020

Background: The Student Wellbeing Process Questionnaire (Student WPQ) has been used to identify predictors of both positive and negative wellbeing. These variables can now be used to investigate whether different aspects of the wellbeing process are associated with academic outcomes.
Aims: The wellbeing process involves established predictors such as exposure to stressors, negative coping, social support, positive personality, and conscientiousness. The wellbeing outcomes are positive (e.g. happiness, positive affect, and life satisfaction), and negative (e.g. stress, anxiety and depression). The aim was to examine associations between these variables and academic outcomes (Grade Point Average [GPA]; perceived efficiency; perceived course stress, and perceived workload).
Methodology: The research described in this paper was carried out with the approval of the ethics committee, School of Psychology, Cardiff University, and the informed consent of the participants (1296 psychology undergraduates; 89.4% female; 49.7% year 1; mean age 19.5 years). An online survey was carried out and this included the Student WPQ and academic outcomes. A MANOVA was conducted to examine associations between the wellbeing process variables and the academic outcomes.
Results: The main factor associated with the academic outcomes was conscientiousness. Those in the high conscientiousness category had higher GPA sores, reported greater efficiency and higher course stress and workload. GPA scores were also associated with student stressors, with those in the high stress category having lower GPA scores. Greater efficiency was associated with higher scores for positive wellbeing and social support, and lower negative coping. Higher course stress was associated with higher scores for exposure to stressors, negative coping and negative wellbeing. Higher negative wellbeing was also associated with higher perceived workload.
Conclusion: Conscientiousness is the best predictor of academic outcomes. Other components of the wellbeing process have selective effects on academic outcomes.

Authors: Kazemian Gholamhossein , Manafi Rasi Alireza , Baroutkoub Mojtaba , Mahdi Sarzaeem Mohammad 
Published: January 2020

Background: Thromboembolic disease is a common complication among patients undergoing total hip and knee arthroplasty. There are a large number of clinical trials demonstrating the efficacy of aspirin and enoxaparin in preventing pulmonary emboli and deep venous thrombosis. This study aimed to investigate the preventive role of aspirin and enoxaparin after knee arthroplasty (TKA).
Methods: In this retrospective study, 160 patients undergoing knee arthroplasty at Imam Hossein Hospital, Tehran, Iran between January 2010 and February 2012 were studied. Patients were divided into treatment groups receiving enoxaparin and aspirin and were evaluated within 28 days after surgery. After examining demographic factors including age and sex, variables such as DVT, pulmonary embolus, infection, transfusion RBCs and mortality were evaluated.
Results: A total thrombosis rate of 0.0125% (one deep venous thrombosis) was observed. The two groups were not significantly different in the number of patients with complications such as DVT, pulmonary embolism, infection, average number of packed RBCs, and mortality.
Conclusion: We believe that course aspirin is as effective and safe as enoxaparin for thromboprophylaxis.

Authors: Ghali Zohra 
Published: January 2020

Aims: The present paper aims to study a set of motives favoring the consumer willingness to buy organic food in the context of developing market (Tunisia). This study also endeavors to examine the moderating role of awareness in the relationships between willingness to buy and its motives.
Place and Duration of Study: This research work was developed from May to December 2019. The hypotheses were tested in a developing country (Tunisia).
Methodology: To test the research hypotheses as well as the overall model fit, the Structural Equation Modeling (SEM) method has been used. A survey was conducted from 16 June to 31 August of 2019 in several supermarkets and organic grocery shops in Tunisia.
Results: The findings of a quantitative study involving 480 Tunisian consumers of organic food products indicate that health consciousness and knowledge of organic food are significant drivers of willingness to buy. The intensity of these relationships is positively moderated by awareness. However, concern for the environment did not prove to exert any significant influence on willingness to buy.
Conclusion: This study provides interesting managerial guidelines for policymakers to switch to organic farming that is beneficial for health and environment. It also allows significant insights for marketers to formulate an effective marketing strategy through exploring some crucial drivers of willingness to buy organic food while enhancing the consumers’ awareness.
Environmental Management Practices of an Apparel Manufacturer in Sri Lanka: A Critique
Authors: Thevanes N. 
Published: January 2020

Environmental degradation considered as one of the critical issues in the current world. To respond to this issue, organizations and businesses around the world seriously focus on environmental protection and management nowadays than before. Organizations strongly committed to adapt several sustainable environmental management practices and initiatives to prove their environmental concern. Meanwhile, it should be noticed that some organizations started pacing towards green washing declaration processes. In this sense, there is a need to explore and identify the sustainable environmental management practices which are actually practiced by the organizations.
Hence, this paper aims to report existing sustainable environmental management practices of the organization and to find out the evidence to support the existing sustainable environmental management practices into practice. In order to achieve the study objectives, secondary data were collected mainly from the published sustainability reports of the selected apparel company for the last two years (2013/2014 and 2014/2015). Further, researchers employed the observation method to confirm whether this company is really carrying out the environmental practices which were reported in their sustainability reports or not. The researchers have identified and highlighted several sustainable environmental management practices under the three main categories such as energy conservation-related practices, water conservation-related practices and earth conservation-related practices through the sustainability reports of the company. Moreover, through the observation, researchers have confirmed that this company is really carrying out the energy conservation-related practices, water conservation-related practices and earth conservation-related practices which were reported in their sustainability reports. This study should be useful to the academics and practitioners to understand actual sustainable environmental management practices of the organizations.

Published: January 2020

AbstractIn acidic soils with high phosphorus (P) fixing capacity, P application at levels higher than crop requirements is common in crops with high P demands such as potato (Solanum tuberosum L.), which could lead to eutrophication. Recycled sources of P fertilizer, such as struvite, can be efficient in meeting crop P demands while minimizing P losses. The objective of this study—conducted in four provinces over 3 yr (2016–2018, with 12 sites in total) in Eastern Canada—was to assess potato response to P fertilizer as triple superphosphate (TSP) or a mixture of TSP with struvite. Eight P treatments were applied with five increasing P rates as TSP (0, 26, 52, 79, and 105 kg P ha−1) and three treatments as a mixture of TSP and struvite (25, 50, and 75% (w/w) struvite) at a rate of 79 kg P ha−1. Phosphorus availability indices measured multiple times over the growing season were composed of Mehlich‐3 extracted P (PM3), soil P adsorbed on anion exchange membranes (PAEMs), and petiole P‐PO4 (Ppetiole) concentrations. There was a potato yield response to P inputs at all sites, with the control treatment showing lower potato yield at all sites. Potato yield, Ppetiole, PM3, and PAEMs were comparable between 100% TSP and TSP+struvite at the same rate, except at one site where struvite at a higher proportion depressed yield and was associated with lower P uptake. Overall, the use of struvite could be a sustainable mean to address long‐term globally P scarcity.
Assessing the economy‐wide impact of food fraud: A SAM‐based counterfactual approach
Authors: Rocchi Benedetto , Romano Donato , Sadiddin Ahmad , Stefani Gianluca 
Published: January 2020

AbstractThis paper proposes a social accounting matrix (SAM)‐based, counterfactual approach to assess the economy‐wide impact of food fraud in a given country and applies it to the Italian economy. The empirical application uses primary data collected by the authority in charge of the monitoring and repression of fraud in food value chains between the years 2007 and 2015. This is a unique dataset to analyze the issue, although it includes only data on food fraud within the country. The results of the SAM simulations show that the share of economy directly and indirectly linked to the supply of irregular food products accounts for 0.5% of the total value of output and is able to activate up to 156 thousand labor units. The net impact of food fraud on output and employment in the whole economy is negative, with losses averaging up to 1.8 billion euros of output and of 20,000 jobs per year, with a relative impact significantly larger in agriculture than in the food industry. These figures reveal an intrinsic fragility of the agri‐food system, especially in those subsectors featuring relatively large price elasticities such as quality products (e.g., wine, olive oil, cheese). The overall conclusion is that food fraud is not only a source of unfair competition to regular production activities but also has an overall contractionary impact on the whole economy due to its directly unproductive rent‐seeking nature.

Collaborative Biosynthesis of a Class of Bioactive Azaphilones by Two Separate Gene Clusters Containing Four PKS/NRPSs with Transcriptional Crosstalk in Fungi
Authors: Huang Xuenian , Zhang Wei , Tang Shen , Wei Suhui , Lu Xuefeng 
Published: January 2020

AbstractAzaphilones are a family of fungal polyketide metabolites with diverse chemical structures and biological activities with a highly oxygenated pyranoquinone bicyclic core. Here, a class of azaphilones possessing a 6/6/6/6 tetracyclic ring system was identified in Aspergillus terreus, and exhibited potential anticancer activities. The gene deletions and biochemical investigations demonstrated that these azaphilones were collaboratively synthesized by two separate clusters containing four core‐enzymes, two nonreducing PKSs, one highly reducing PKS, and one NRPS‐like. More interestingly, we found that the biosynthesis is coordinately regulated by a crosstalk mechanism between these two gene clusters based on three transcriptional factors. This is a meaningful mechanism of fungal secondary metabolism, which allows fungi to synthesize more complex compounds and gain new physiological functions. The results provide a new insight into fungal natural product biosynthesis.
Decarboxylative Conjunctive Cross‐coupling of Vinyl Boronic Esters using Metallaphotoredox Catalysis
Authors: Mega Riccardo S. , Duong Vincent K. , Noble Adam , Aggarwal Varinder K. 
Published: January 2020

AbstractThe synthesis of complex alkyl boronic esters through conjunctive cross‐coupling of vinyl boronic esters with carboxylic acids and aryl iodides is described. The reaction proceeds under mild metallaphotoredox conditions and involves an unprecedented decarboxylative radical addition/cross‐coupling cascade of vinyl boronic esters. Excellent functional‐group tolerance is displayed, and application of a range of carboxylic acids, including secondary α‐amino acids, and aryl iodides provides efficient access to highly functionalized alkyl boronic esters. The decarboxylative conjunctive cross‐coupling was also applied to the synthesis of sedum alkaloids.

Published: January 2020

ABSTRACTUsing silica sol and potassium silicate as the raw materials and styrene butadiene emulsion as modifier, a stable high‐modulus potassium silicate composite material was prepared with zinc powder at a ratio of 3:7 in the preparation of high modulus potassium silicate waterborne inorganic zinc‐rich primer. Coatings were applied to steel panels with a composition of 8, 10, 12, and 15 wt % styrene butadiene latex. Scanning electron microscopy, energy‐dispersive spectrometry, X‐ray photoelectron spectroscopy, and electrochemical tests were utilized to analyze the anticorrosion properties of the samples. According to the results of electrochemical tests, the addition of styrene butadiene latex improves the corrosion resistance of coatings. The best corrosion performance can be obtained for the sample with 10 wt % styrene butadiene latex. © 2020 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2020,137, 48918.
Alternating Current Electrolysis for the Electrocatalytic Synthesis of Mixed Disulfide via Sulfur–Sulfur Bond Metathesis towards Dynamic Disulfide Libraries
Authors: Sattler Lars Erik , Otten Chris Josef , Hilt Gerhard 
Published: January 2020

AbstractA novel approach of electrolysis using alternating current was applied in the sulfur–sulfur bond metathesis of symmetrical disulfides towards unsymmetrical disulfides. As initially expected, a statistical distribution in disulfides was obtained. Furthermore, the influence of electrode polarisation by alternating current was investigated on a two‐disulfide matrix. The highly dynamic nature of this chemistry resulted in the creation of dynamic disulfide libraries by expansion of the matrices, consisting of up to six symmetrical disulfides. In addition, mixing of matrices and stepwise expanding of a matrix by using alternating current electrolysis were realised.
Crystalline Nitridophosphates by Ammonothermal Synthesis
Authors: Mallmann Mathias , Wendl Sebastian , Schnick Wolfgang 
Published: January 2020

AbstractNitridophosphates are a well‐studied class of compounds with high structural diversity. However, their synthesis is quite challenging, particularly due to the limited thermal stability of starting materials like P3N5. Typically, it requires even high‐pressure techniques (e.g. multianvil) in most cases. Herein, we establish the ammonothermal method as a versatile synthetic tool to access nitridophosphates with different degrees of condensation. α‐Li10P4N10, β‐Li10P4N10, Li18P6N16, Ca2PN3, SrP8N14, and LiPN2 were synthesized in supercritical NH3 at temperatures and pressures up to 1070 K and 200 MPa employing ammonobasic conditions. The products were analyzed by powder X‐ray diffraction, energy dispersive X‐ray spectroscopy, and FTIR spectroscopy. Moreover, we established red phosphorus as a starting material for nitridophosphate synthesis instead of commonly used and not readily available precursors, such as P3N5. This opens a promising preparative access to the emerging compound class of nitridophosphates.

Published: January 2020

SummaryNetwork‐on‐chip (NoC) is a new design method of system‐on‐chip used in very large scale integrated circuit (VLSI) systems. It is an important issue for choosing the appropriate topology for NoC. Wirelength and layout area are significant parameters affecting NoC due to the restriction of chip area. In this paper, we propose a new interconnection network called the incomplete ternary n‐cube for parallel computing systems. Then, a linear algorithm is proposed to layout incomplete ternary n‐cube network onto torus NoC. Furthermore, the failure of interconnection network is also taken into account, and a fault‐tolerant layout of incomplete ternary n‐cube with faulty edges into torus NoC is verified. Theoretical analysis demonstrates that the proposed algorithm can reduce the network cost and wirelength, which be conducive to estimate the wire length and chip area.
Synthesis of 4‐Cyanoindole Nucleosides, 4‐Cyanoindole‐2ʹ‐Deoxyribonucleoside‐5ʹ‐Triphosphate (4CIN‐TP), and Enzymatic Incorporation of 4CIN‐TP into DNA
Authors: Passow Kellan T. , Antczak Nicole M. , Sturla Shana J. , Harki Daniel A. 
Published: January 2020

Abstract4‐Cyanoindole‐2ʹ‐deoxyribonucleoside (4CIN) is a fluorescent isomorphic nucleoside analogue with superior spectroscopic properties in terms of Stokes shift and quantum yield in comparison to the widely utilized isomorphic nucleoside analogue, 2‐aminopurine‐2ʹ‐deoxyribonucleoside (2APN). Notably, when inserted into single‐ or double‐stranded DNA, 4CIN experiences substantially less in‐strand fluorescence quenching compared to 2APN. Given the utility of these properties for a spectrum of research applications involving oligonucleotides and oligonucleotide‐protein interactions (e.g., enzymatic processes, DNA hybridization, DNA damage), we envision that additional reagents based on 4‐cyanoindole nucleosides may be widely utilized. This protocol expands on the previously published synthesis of 4CIN to include synthetic routes to both 4‐cyanoindole‐ribonucleoside (4CINr) and 4‐cyanoindole‐2ʹ‐deoxyribonucleoside‐5ʹ‐triphosphate (4CIN‐TP), as well as a method for the enzymatic incorporation of 4CIN‐TP into DNA by a polymerase. These methods are anticipated to further enable the utilization of 4CIN in diverse applications involving DNA and RNA oligonucleotides. © 2020 by John Wiley & Sons, Inc.Basic Protocol 1: Synthesis of 4‐cyanoindole‐2ʹ‐deoxyribonucleoside (4CIN) and 4CIN phosphoramidite 4Basic Protocol 2: Synthesis of 4‐cyanoindole‐ribonucleoside (4CINr)Basic Protocol 3: Synthesis of 4‐cyanoindole‐2ʹ‐deoxyribonucleoside‐5ʹ‐triphosphate (4CIN‐TP)Basic Protocol 4: Steady state incorporation kinetics of 2AP‐TP and 4CIN‐TP by a DNA polymerase
