Published: March 2022

The objective of this study was to investigate the chemical composition and in vitro antifungal activity of Mentha × Piperita L. (peppermint) essential oil (EO) against some plant pathogenic fungi (Alternaria alternata, Penicillium expansum, Rhizoctonia solani, and Rhizopus stolonifer). Antifungal activity of EO against the selected fungi was conducted using the agar diffusion method by adding peppermint EO concentrations (0, 250, 500, 750, 1000, and 2000 ppm). The gas chromatography-mass spectrometry (GC-MS) analysis of peppermint EO showed that the main constituent was menthol (36.4%), followed by menthone (27.7%) and menthyl acetate (11.2%). The mycelium growth of the selected fungi was significantly inhibited by peppermint EO. Light and electron microscopy studies showed that mycelium morphology was seriously changed after treatment with peppermint essential oil. The level of malondialdehyde illustrated that peppermint EO led to lipid peroxidation in the fungal pathogens. Therefore, due to its antifungal properties, peppermint EO can be used as an additive in the food industry and as an active substance in pharmaceuticals.

Authors: Borowy Andrzej , Kapłan Magdalena 
Published: March 2022

The usefulness of 3 herbicides and flame weeding in lemon balm sown directly into the field was assessed in a two-year experiment. Glufosinate-ammonium (600 g∙ha–1) and flame weeding (90 kg propane∙ha–1) were applied 12–13 days after lemon balm sowing, i.e. shortly after weed emergence and 4 days before crop emergence. Bentazon (960 g∙ha–1) and fluazifop-P-butyl (150 g∙ha–1) were sprayed approximately 3 weeks after sowing, during the emergence of lemon balm, and when the weeds were in the cotyledon – 2–4 true leaves stage. All of the studied weed control methods significantly reduced the number and fresh weight of weeds growing 4 weeks after lemon balm sowing. The most effective method was spraying with glufosinate-ammonium, which controlled 69–76% of weeds. The efficiency of flame weeding was slightly lower. Bentazon caused slight, temporary chlorosis of some lemon balm cotyledons. Content of essential oil (1.9–2.1%), its composition and content of rosmarinic acid (2.08–2.44%) in lemon balm leaves, as well as content of total nitrogen (2.18–2.55%), phosphorus (0.30–0.32%), potassium (2.94–3.22%), calcium (1.02–1.60%), and magnesium (0.30–0.32%) in lemon balm raw material were independent of the weeding method. Content of essential oil, phosphorus, potassium and calcium were significantly higher in the dryer year. Studied weed control methods proved useful in the cultivation of lemon balm from direct sowing into the field. Methods with total action (flaming and glufosinate-ammonium) were more effective than those with selective herbicides (bentazon and fluazifop-P-butyl).

Published: March 2022

The present study was carried out during both 2018 and 2019 growing seasons on ‘Crimson Seedless’ grape vine grown on sandy soil. Vines received water, salicylic acid 200 mg/L, chitosan 10 g/L, putrescine 5 mM, phenylalanine 400 mg/L, ascorbic acid 500 mg/L, citric acid 700 mg/L, gibberellic acid 20 mg/L, active dry yeast 15 g/L at véraison (change of color) stages and at 10 days before harvesting time. Fruit clusters were harvested when total soluble solids (TSS) reached 16%, stored at 0°C and 85–90 relative humidity for 35 days then kept 2 days at shelf life (25 ±2°C and air humidity 70 ±2). Results at harvest time showed that, salicylic acid, putrescine, gibberellic acid and yeast increased average berry weight and juice volume. Salicylic acid, chitosan, putrescine, citric acid and gibberellic acid maintained the berry adherence strength and firmness. Salicylic acid, chitosan, putrescine and phenylalanine increased berry red color, as well as berry anthocyanin, TSS and sugars content. Highest acidity content was obtained by salicylic acid, chitosan, citric acid and gibberellic acid spraying. Results after cold storage and shelf life showed that, berry weight loss decreased significantly by all chemical sprays, except phenylalanine. High maintenance of berry adherence strength and firmness occurred by gibberellic acid followed by putrescine. All chemicals reduced the unmarketable grapes except the phenylalanine.

Published: March 2022

Morels are well known due to their nutritional and food value since ancient human history. In this study, biochemical and proteomic analyses were carried out on the ascocarp of Morchella tridentina Bres. For this, several ascocarp of M. tridentina were collected from different sites of Neelum Valley Azad Jammu and Kashmir, Pakistan. Identification was confirmed by phylogenetic sequencing using nuclear ribosomal DNA bar-coding technique along with morph-anatomical analysis. During the biochemical analysis, different bioactive compounds used in drugs to treat cancer, heart diseases, edema (veprisinium, visnagin, and bumetanide), and breast cancer (petunidin) were identified. Cerulinin, daidzein, guanthidin and okanin (imperative compounds) were also detected. Furthermore, protein analysis by FTICR/MS/Orbitrap revealed the presence of 921 proteins belonging to 171 protein groups having 165 unique peptide sequences. The study shows that this morel could be used as a source of bioactive substances to develop anticancer, antifungal, and antiviral drugs in the future. This fruitful addition of M. tridentina in Mycota of Pakistan increases the number of morels to three.

Summary
Investigation of the detailed pyrolysis characteristics of tobacco raw materials is important for the understanding of product design and consumption. In this work, pyrolysis characteristics and kinetic models of cigar filler tobacco (CFT), cigar wrapper tobacco (CWT), and flue-cured tobacco (FCT) were investigated by using a thermogravimetric analyzer coupled with Fourier-transform infrared spectroscopy (TG-FTIR). The pyrolysis of different tobacco samples could be divided into four stages based on the derivative thermogravimetric analysis (DTG) curves. Flue-cured tobacco underwent a marked decomposition process at lower temperatures (about 200 °C), while the thermal decomposition of cigar tobacco occurs at higher temperatures. During the pyrolysis process, evolved gases including H2O, CO2, CH4, CO, carbonyls, alcohols, phenols and aromatic compounds were detected by FTIR. CWT released more CO2 than CFT, while the amount of CO2, CH4, CO and aromatic compounds released by flue-cured tobacco was lower than that of cigar tobacco. The pyrolysis kinetics of tobacco leaves were further analyzed and compared through the isoconversional FWO (Flynn-Wall-Ozawa) and KAS (Kissinger-Akahira-Sunose) methods. The activation energy of FCT (from 100.1 kJ mol−1 to 192.1 kJ mol−1) was lower than that of CFT (from 207.36 kJ mol−1 to 319.28 kJ mol−1) and CWT (from 160.40 kJ mol−1 to 260.45 kJ mol−1). The thermal decomposition kinetics of different tobaccos were analyzed by Málek and Coats-Redfern methods.
Effects of lagging projectification in the public sector on realizing infrastructure projects
Authors: Wagner Reinhard F. , Radujkovic Mladen 
Published: March 2022

Abstract
The public sector in Germany lags behind the economy in terms of projectification, i.e., the prevalence of projects and experience in applying project management. This has significant implications for realizing complex infrastructure projects in which the public sector is involved as one of the main actors. Nowadays, projectification represents a particular way of thinking about how to embrace a series of dynamic and challenging changes, design them, and implement them effectively for the benefit of society. A quantitative study of projectification in society in Germany was the starting point for our research, the results of which we compared with data from earlier studies of projectification in the economy. Using an interpretative case study drawing on insights from the Berlin Airport, we analyzed the impact of lagging projectification in the public sector in Germany on realizing infrastructure projects to propose suitable approaches. The results of this case study reveal significant effects of lagging projectification in the public sector of Germany on realizing infrastructure projects. In the case of the Berlin BER Airport, an inadequate governance system led to a 9-year delay in the completion date and a 250% overrun of costs directly attributable to the project. This could have been avoided by involving the private construction industry more collaboratively, by building on previous experiences gained, and by a more cooperative way of project planning and implementation. To guide future research, hypotheses are derived that can be used to analyze the underlying problem in greater depth and to derive recommendations for action.
Choosing Between Innovative and Traditional Payment Systems: An Empirical Analysis of European Trends
Authors: Camilleri Silvio John , Agius Christabelle 
Published: March 2022

The current variety of payment methods offers faster settlements and reasonable security, however payment innovations may be met with inertia or resistance. This study addresses the characteristics which may be associated with the adoption of novel payment systems and salient user trends in this respect. We investigate whether the reliance on traditional payment methods across European countries is related to socio-economic aspects, and also delve into the payment habits at the individual level. Results from an econometric model suggest that financial market development and education-related factors are negatively related to the use of traditional payment instruments. When considering consumer payment habits and awareness about novel facilities, particular differences across generations emerged. Cash and debit cards are most widely used and it seems that such choices are related to perceived convenience rather than due to aversion towards novel systems.
The Impact of Emotional Experiences of Innovation Champions on Innovation Outcomes
Authors: Swart-Opperman Christina , Dharani Babar , April Kurt 
Published: March 2022

This article aims to explore the impact of emotions and behaviours of innovation champions on organisation innovation outcomes. Our research suggests that champions do not necessarily contribute to successful outcomes. This could be ascribed to the fact that the role of the innovation champion is often oversimplified, while the context and specific emotional experiences of the champion impact champion behaviour. Therefore, for the purposes of this article, we considered the innovation champion as an internal role player, soliciting support for innovation and thereby influencing outcomes. The study reanalyses the interview data of twenty innovation champions from six African countries within the financial services industry. The article provides additional insights into the complexities associated with ‘championing’, linked to the champion’s own emotional experiences, discretionary and citizenship behaviours. The study reveals that, although there is an increased awareness of the factors triggering champion behaviours, the description of the fluid role of the champion remains a challenge. The role of the innovation champion and the question whether such roles are over- or underrated will thus continue to receive attention in literature.

Keywords: innovation champion, champion identity, harmful champion behaviour, champion emotional experience, champion role, champion behaviour
Pseudo ST segment elevation myocardial infarction in a case of apical hypertrophic cardiomyopathy
Authors: Okonkwo Ekene Kenneth , Han Jennie , Attar Nadeem 
Published: March 2022

Background:
Apical hypertrophic cardiomyopathy (AHCM) is a relatively rare variant of hypertrophic cardiomyopathy. The condition is associated with numerous clinical and electrocardiogram (ECG) features, some of which are well documented in the literature.

Case Presentation:
We present a case of a 77-year-old female who presented with a syncopal episode. Her ECG showed lateral ST segment elevation and her cardiac biomarkers were not in keeping with a myocardial infarction. She was diagnosed with AHCM based on characteristic findings on echocardiography. The association between AHCM and lateral ST segment elevation is one that has only been described in a handful of cases in literature.

Conclusion:
The authors hope that in presenting this case we can add to the body of literature and remind readers to be aware of the possibility that lateral ST segment elevation may be an indicator of AHCM, especially when this electrocardiographic feature occurs in the absence of the other well-known causes of ST segment elevation.
