Color and Ascorbic Acid Degradation Kinetics of Red Pepper (Capsicum annuum L.) Slices during Vacuum Drying
Authors: DEMİRAY Engin , TÜLEK Yahya
Published: April 2020

Red pepper slices were dried in a vacuum dryer at three different temperatures (45, 55 and 65°C) and two absolute pressures (21.5 kPa and 48.0 kPa). Drying temperature and absolute pressure significantly influenced drying time. Degradation kinetics of ascorbic acid in red pepper slices during vacuum drying followed a first-order kinetic model. The highest ascorbic acid retention occurred in the samples dried the combination of 45°C and 21.5 kPa. In addition to the temperature effect, the drying absolute pressure was effective on the loss of ascorbic acid. The activation energy values for ascorbic acid under both absolute pressure of 48.0 kPa and 21.5 kPa were calculated as 70.85 kJ/mol and 81.43 kJ/mol, respectively. The sample surface color degradation after drying was also determined. The color values (Hunter L, a and b) decreased, while ΔE (The color difference) increased during drying. Mathematical modeling of color degradation kinetics indicated that both the zero-order and first-order kinetic model were found to describe the Hunter L, a and b values. However, ΔE followed zero-order kinetic model.

Sarımsak (Allium sativum L.) insan sağlığına yararlı olduğu bilinen ve dünya mutfağında çok eski zamanlardan bu yana yer alan bir sebzedir. Sarımsağın karakteristik kokusu ve tadı nedeniyle çiğ olarak tüketimi sınırlıdır. Bu nedenle son yıllarda sağlığa yararlı etkileri korunarak, istenmeyen kokularından izole edilmiş yeni sarımsak ürünlerinin eldesi için birçok metot denenmektedir. Bu amaçla üretilmiş olan siyah sarımsak birçok ülke ve hatta ülkemizde çok fazla bilinmemekte ve tüketilmemektedir. Yapılan bu çalışma ile siyah sarımsağın yapısında bulunan bazı fenolik bileşikler Yüksek Performanslı Sıvı Kromatografisi (HPLC) ile araştırılmıştır. Ayrıca metanol ile hazırlanan ekstraktının Pseudomonas aeruginosa PA01’in sentezlediği ve patogenezinde önemli rolü olan piyosiyanin ve elastaz üretimi ile biyofilm oluşumu üzerine inhibisyon etkisine bakılmıştır. HPLC analiz sonuçlarına göre fenolik bileşiklerden kuersetin, klorojenik asit, vanillin, p-kumarik asit, p-hidroksi benzoik asit farklı oranlarda tespit edilmiştir. Mikrobiyal aktivite sonuçlarına göre ise siyah sarımsak metanol ekstraktının piyosiyanin ve elastaz üretimi ile biyofilm oluşumu üzerine (sırasıyla %38, %28 ve %84 inhibisyon oranlarıyla) inhibisyon etkisinin anlamlı olduğu görülmüştür.

Authors: Gündeş Fatma Aslı , Sönmez İlker
Published: April 2020

The effect of different nitrogen (N) treatments on the nutrient contents of tomato (Lycopersicon esculentum Mill., cv. ‘Tayfun F1’) under different boron (B) concentrations were investigated in greenhouse conditions with four replications. Four different levels of B (0, 5, 10 and 20 mg kg–1) and three levels of N (100, 200, 300 mg kg–1) were used in this research. The results showed that tomato plant growth was negatively affected with increasing B concentrations and symptoms of boron toxicity were observed. The tomato leaf nutrient concentrations were increased in all plants with B and N treatments and 20 mg kg–1 B and 300 mg kg–1 N treatments were determined to be more effective compared to the others. 20 mg kg–1 B and 100 mg kg–1 N treatment caused the highest micro element concentrations of tomato leaf. This could be interpreted as N application having a dilution effect to be able to maintain development under conditions of toxicity of B. The plants growth under boron toxicity conditions showed increased vegetation with increasing N applications which was attributed to the dilution effect.

A greenhouse experiment was conducted to estimate the impacts of various deficit irrigation regimes (DIR) as 100 (control), 75 (medium DIR, MDIR) and 50% (severe DIR, SDIR) of field capacity (FC) on the growth and photosynthetic traits of five rootstocks (two vigorous seedling including Pyrus betulifolia and Dargazi seedling (P. communis L.) as well as three clonal semi-dwarfing rootstocks including OH×F69, OH×F87 and Pyrodwarf in 2016. Although in all studied rootstocks the growth and photosynthetic parameters negatively affected under MDIR and SDIR conditions, but P. betulifolia and Pyrodwarf rootstocks had the better growth rate, chlorophylls, total carbohydrates, relative water content, sub-stomatal CO2 (Ci), photosynthesis rate (PN) and instantaneous water use efficiency compared to others. Therefore, the use of P. betulifolia and Pyrodwarf (as drought tolerance rootstocks) could be more appropriate under various DIR conditions.

Published: April 2020

Field inoculation experiments were performed during 2015–2017, in south-eastern part of Poland. The pathogenicity of F. crookwellense was estimated based on the kernels yield reduction of 10 selected oat genotypes. Panicles of oat were inoculated with conidial suspension of F. crookwellense strain No. 72 which caused a reduction in kernels yield by 28.54% and kernels number per panicle by 28.07%, compared to the control. The lowest yield reduction, as a result of the panicle inoculation with F. crookwellense, was found in the case of the cultivar ‘Pablo’ (18.73%), while the highest in the case of breeding line POB 961-1344/13 (36.4%) and cv. ‘Kozak’ (34.3%). Statistically the highest average yield reduction was observed in year 2016, when a higher amount of rainfall, especially in July (just after inoculation) and higher temperature, compared to the long-term standard, were observed. During the period between inoculation and harvest, F. crookwellense was able to produce nivalenol, fusarenone X and zearalenone in oat kernels at the average level of 0.065 mg∙kg-1, 0.026 mg∙kg-1 and 0.015 mg∙kg-1 respectively.

Published: April 2020

Bulked segregant analysis combined with specific length amplified fragment sequencing techniques have been applied to determine the fine genetic mapping of fruit flesh thickness-related genes in cucumber. Herein, the Csa2M058670.1 gene was subjected to real time fluorescence quantitative PCR (qRT-PCR) and sequence analysis, indicating a strong correlation with cucumber fruit flesh thickness. Expression and characterisation of the Csa2M058670.1 gene were performed based on previous studies. The results of the fluorescence-based quantitative PCR showed that Csa2M058670.1 was expressed in all organs, but levels were highest in fruit peel, fruit flesh, and female flowers. Furthermore, Csa2M058670.1 expression was induced by abiotic stresses including drought, low temperature, and high salt. Domain analysis revealed that the protein encoded by Csa2M058670.1 possesses an SET (Su(var), Enhancern of zeste CE(z), and Trithorax) domain that may control cell division and differentiation. Therefore, we speculated that Csa2M058670.1 might affect fruit flesh thickness in cucumbers by influencing cell division.

Published: April 2020

The experimental studies were conducted from 2015–2017 years in two cycles. The aim of the research was to determine a better grafting time and a choice of an appropriate rootstock for the propagation of two cultivars of mountain pine (Pinus mugo Turra). The influence of the grafted cultivar and rootstock used on the level of chloroplast pigments in the needles was also checked. The studies concerned two cultivars of mountain pine (Pinus mugo) ‘Grześ’ and ‘Zundert’, which were grafted on four different rootstocks: Pinus contorta (Dougl. ex Loud.), Pinus nigra (Arn.), Pinus sylvestris (L.) and Pinus mugo subsp. uncinata (Ramond Domin) in two dates: 20 January and 15 March. The highest percentage of graft success was obtained for the two cultivars on Pinus uncinata and Pinus contorta rootstocks. A later term of grafting procedure affected bigger effectiveness of grafting of the two studied cultivars, except for the graft success on Pinus sylvestris rootstock. The highest increments of side shoots and lengths of main stems for ‘Grześ’ cultivar were obtained on Pinus nigra, and for ‘Zundert’ the influence of the rootstock on the above mentioned parameters was not evident. No significant differences in the number of increments in the first and second year of studies were observed. The highest level of chlorophyll A and B was found in the needles of ‘Grześ’ cultivar, independently from the rootstock used. Among tested rootstocks, only Pinus nigra had a significant impact on a higher content of chlorophyll B in the needles of the studied cultivars of mountain pine trees.

Published: April 2020

Diazinon poisoning is an important issue in occupational, clinical, and forensic toxicology. While sensitive and specific enough to analyse diazinon in biological samples, current methods are time-consuming and too expensive for routine analysis. The aim of this study was therefore to design and validate a simple dispersive liquid-liquid microextraction (DLLME) for the preparation of urine samples to be analysed for diazinon with high performance liquid chromatography with diode-array detector (HPLC-DAD) to establish diazinon exposure and poisoning. To do that, we first identified critical parameters (type and volume of extraction and disperser solvents, pH, surfactant, and salt concentrations) in preliminary experiments and then used central composite design to determine the best experimental conditions for DLLME-HPLC-DAD. For DLLME they were 800 µL of methanol (disperser solvent) and 310 µL of toluene (extraction solvent) injected to the urine sample rapidly via a syringe. The sample was injected into a HPLC-DAD (C18 column, 250×4.6 mm, 5 μm), and the mobile phase was a mixture of acetonitrile and buffer (63:37 v/v, pH 3.2; flow rate: 1 mL/ min). Standard calibration curves for diazinon were linear with the concentration range of 0.5–4 µg/mL, yielding a regression equation Y=0.254X+0.006 with a correlation coefficient of 0.993. The limit of detection and limit of quantification for diazinon were 0.15 µg/mL and 0.45 µg/mL, respectively. The proposed method was accurate, precise, sensitive, and linear over a wide range of diazinon concentrations in urine samples. This method can be employed for diazinon analysis in routine clinical and forensic toxicology settings.
Chiral separation of beta-blockers by high-performance liquid chromatography and determination of bisoprolol enantiomers in surface waters

Published: April 2020

Beta-blockers are chiral compounds with enantiomers that have different bioactivity, which means that while one is active, the other can be inactive or even harmful. Due to their high consumption and incomplete degradation in waste water, they may reach surface waters and affect aquatic organisms. To address this issue we developed a chromatographic method suitable for determining beta-blocker enantiomers in surface waters. It was tested on five beta-blockers (acebutolol, atenolol, bisoprolol, labetalol and metoprolol) and validated on bisoprolol enantiomers. Good enantioseparation of all analysed beta-blockers was achieved on the Chirobiotic V column with the mobile phase composed of methanol/acetic acid/triethylamine (100/0.20/0.15 v/v/v) at a flow rate of 0.5 mL/min and column temperature of 45 °C. Method proved to be linear in the concentration range from 0.075 µg/mL to 5 µg/mL, and showed good recovery. The limits of bisoprolol enantiomer detection were 0.025 µg/mL and 0.026 µg/mL and of quantification 0.075 µg/mL and 0.075 µg/mL. Despite its limitations, it seems to be a promising method for bisoprolol enantiomer analysis in surface water samples. Further research could focus on waste water analysis, where enantiomer concentrations may be high. Furthermore, transferring the method to a more sensitive one such as liquid chromatography coupled with tandem mass spectrometry and using ammonium acetate as the mobile phase additive instead of acetic acid and triethylamine would perhaps yield much lower limits of detection and quantification.

Fractional Interaction of Financial Agents in a Stock Market Network
Authors: Balcı Mehmet Ali
Published: April 2020

In this study, we present a model which represents the interaction of financial companies in their network. Since the long time series have a global memory effect, we present our model in the terms of fractional integro-differential equations. This model characterize the behavior of the complex network where vertices are the financial companies operating in XU100 and edges are formed by distance based on Pearson correlation coefficient. This behavior can be seen as the financial interactions of the agents. Hence, we first cluster the complex network in the terms of high modularity of the edges. Then, we give a system of fractional integro-differential equation model with two parameters. First parameter defines the strength of the connection of agents to their cluster. Hence, to estimate this parameter we use vibrational potential of each agent in their cluster. The second parameter in our model defines how much agents in a cluster affect each other. Therefore, we use the disparity measure of PMFGs of each cluster to estimate second parameter. To solve model numerically we use an efficient algorithmic decomposition method and concluded that those solutions are consistent with real world data. The model and the solutions we present with fractional derivative show that the real data of Borsa Istanbul Stock Exchange Market always seek for an equilibrium state.
Discrete Normal Vector Field Approximation via Time Scale Calculus
Authors: Akgandüller Ömer , Atmaca Sibel Paşalı
Published: April 2020

The theory of time scales calculus have long been a subject to many researchers from different disciplines. Beside the unification and the extension aspects of the theory, it emerge as a powerful tool for mimetic discretization process. In this study, we present a framework to find normal vector fields of discrete point sets in ℝ3 by using symmetric differential on time scales. A surface parameterized by the tensor product of two time scales can be analogously expressed as the vertex set of non-regular rectangular grids. If the time scales are dense, then the discrete grid structure vanishes. If the time scales are isolated, then the further geometric analysis can be executed by using symmetric dynamic differential. Moreover, we present an algorithmic procedure to determine the symmetric dynamic differential structure on the neighborhood of points in surfaces. Our results indicate that the method we present has good approximation to unit normal vector fields of parameterized surfaces rather than the Delaunay triangulation for some points.

Authors: Borodina Olena , Rykovska Oksana
Published: April 2020

Subject and purpose of work: Human capital is one of the key drivers of rural economic development. The purpose of this paper was to study the main assets of human capital in rural areas and to evaluate this human capital; to identify development trends and devise the recommendations for increasing the impact of human capital in Ukraine’s rural areas on individual incomes and economic growth.

Materials and methods: The research focuses on evaluating the key assets of human capital in the rural areas of Ukraine – educations, health, qualifications, age and the integral evaluation of rural human capital. The data was gathered by random surveys of household living conditions conducted by the State Statistics Committee of Ukraine. Annual surveys cover 10,500 households.

Results: Results demonstrate that there were positive dynamics under the education component, while the health component was constantly in decline. The quantitative scoring of assets allowed preparing an integrated evaluation of human capital in rural areas of Ukraine and observing the dynamics of change in years. This indicator had declined before 2008. A decrease in the level of rural human capital in Ukraine started with the activation of large-scale agri-business in the late 1990s. Since 2009, human capital in rural areas has been increasing. The dynamics of human capital development in the rural areas of post- Euromaidan Ukraine demonstrate the specific nature of its capitalisation. Profit per human capital in rural areas depends not on its rate but on the human capital (holder) employment profile.

Conclusions: Received evaluations could be used for separation of priority state policy actions for balanced development, quantitative renovation and accumulation of human capital in rural areas.

Faktor kedua adalah jenis mulsa yang terdiri dari 3 taraf yaitu tanpa mulsa, mulsa plastik hitam perak, dan mulsa jerami. Interaksi antara volume irigasi dan jenis mulsa meningkatkan pertumbuhan tinggi tanaman, jumlah daun, jumlah anakan, volume akar, jumlah akar, bobot kering, diameter umbi, dan bobot basah umbi per rumpun. Kombinasi volume irigasi 1.50 Eo dengan mulsa plastik menghasilkan bobot basah umbi tertinggi dan tidak berbeda nyata dengan volume irigasi 0.50 Eo dan 0.75 Eo pada mulsa plastik serta volume irigasi 1.00 Eo dan 1.50 Eo tanpa pemberian mulsa. Kombinasi volume irigasi 0.50 Eo dengan pemakaian mulsa plastik direkomendasikan untuk alasan efisiensi pemakaian air dan penggunaan air yang lebih sedikit.

Five Maturity Levels of Managing AI: From Isolated Ignorance to Integrated Intelligence
Authors: Lichtenthaler Ulrich
Published: April 2020

To guide future discussions about managing artificial intelligence (AI), this article suggests an AI management framework with five maturity levels, which are comparable to the five levels of the autonomous driving framework from no automation to complete automation. If companies move beyond Isolated Ignorance (Level 0), they are characterized by an Initial Intent (Level 1), which typically evolves towards an Independent Initiative (Level 2). A more advanced management leads to Interactive Implementation (Level 3) and Interdependent Innovation (Level 4). On this basis, a close combination of AI and human knowledge enables a sustainable competitive advantage with Integrated Intelligence (Level 5). This framework draws on the intelligence-based approach to company performance, and it provides the basis for an AI maturity assessment in organizations. It further helps to identify many firms’ managerial challenges as well as major organizational limitations even in those firms that are often considered as AI leaders.

Alcohol_Focused Drowning Prevention Campaigns: What Do We Know and What Should We Do Now?
Authors: Calverley Hannah , Petrass Lauren , Blitvich Jennifer
Published: April 2020

Alcohol and drugs have been identified as key risk factors for youth (aged 15-24 years) and adult drownings in high-income countries (HIC). Whilst alcohol specific drowning prevention education programs have been developed and implemented, youth continue to be over-represented in drowning statistics, including those linked with alcohol. Therefore, this project aimed to: (i) review and assess all alcohol themed drowning prevention campaigns within HICs; (ii) determine whether the campaign had undergone evaluation for effectiveness; and (iii) provide recommendations to improve the effectiveness of future interventions. For each of the eighty-one HICs identified for the 2019 fiscal year, searches of peer-reviewed literature (through academic databases) and grey literature (through webpages and emails to organisations) were conducted. Twelve alcohol focused campaigns were identified, with only two providing limited information about program evaluation. For most campaigns identified, there was a dearth of information available and therefore assessment of campaign quality was unfeasible. This brief report highlights a lack of alcohol themed drowning prevention campaigns in HIC, and an absence of evaluations on their effectiveness. Implications associated with a lack of program evaluation are discussed and adoption of the recommendations from this brief report should enhance the quality of future research in this area.

Authors: de Oliveira Silva Danilo , Pazzinatto Marcella Ferraz , Rathleff Michael Skovdal , Holden Sinéad , Bell Emily , Azevedo Fábio , Barton Christian
Published: April 2020

Objective

To evaluate the effect of education interventions compared with any type of comparator on managing patellofemoral pain (PFP).

Design

Intervention systematic review. PROSPERO identifier: CRD42018088671.

Literature Search

MEDLINE, Embase, CINAHL, and Web of Science were searched for studies evaluating the effect of education on clinical and functional outcomes in people with PFP.

Study Selection Criteria

Two reviewers independently assessed studies for inclusion and quality. We included randomized controlled trials on PFP where at least 1 group received an education intervention (in isolation or in combination with other interventions).

Data Synthesis

Available data were synthesized via meta-analysis where possible; data that were not appropriate for pooling were synthesized qualitatively. Interpretation was guided by the Grading of Recommendations Assessment, Development and Evaluation approach.

Results

Nine trials were identified. Low-credibility evidence indicated that health education material alone was inferior to exercise therapy for pain and function outcomes. Low- and very low–credibility evidence indicated that health professional–delivered education alone produced outcomes similar to those of exercise therapy combined with health professional–delivered education for pain and function, respectively.

Conclusion

Health professional–delivered education may produce similar outcomes in pain and function compared to exercise therapy plus health professional–delivered education in people with PFP. J Orthop Sports Phys Ther 2020;50(7):388–396. Epub 29 Apr 2020. doi:10.2519/jospt.2020.9400
