The Reaction of the Greek Stock Market to IFRS 16
Authors: ROMPOTIS Gerasımos
Published: June 2023

In this paper, we examine if the implementation of the IFRS 16 about leases had an impact on the stocks traded on Athens Exchange. We use a sample of 79 listed companies to examine whether the prices and the risk of their stocks were affected by the new accounting standard. In doing so, we conduct an event study to estimate abnormal return and volatility of stocks around the publication dates of the sample’s financial statements for year 2019. Similar estimates are prepared for year 2018, which is used as the control year. Afterwards, we compute three representative financial ratios concerning the companies’ profitability, leverage and liquidity. Finally, we check the validity of three assumptions about the impact of IFRS 16 on stock performance and volatility; 1) higher profitability results in higher stock returns and lower volatility, 2) higher leverage ratios, leads to lower stock returns and increased risk, and 3) decreased liquidity results in lower stock returns and increased risk. The empirical findings do not verify these assumptions.

This study investigated the microorganisms associated with the spoilage of tomato (Lycopersicum esculentum) obtained from two markets in Jahun town, Jahun Local Government in Jigawa State, Nigeria. A total of five species of bacteria were isolated and identified viz: Bacillus subtilis, B. aureus, Escherichia coli, Klebsiella aerogenes and Staphylococcus aureus. The most prevalent bacterial isolate was Bacillus subtilis with 24% and was found in all samples from the two markets. Klebsiella aerogenes was the least prevalent isolate with 0.8% and was found in samples from Jahun Central Market only. The fungal isolates were Penicilium notatum, Mucor mucido and Aspergillus niger. Whereas, Mucor mucido was the most prevalent with 26.4% and was found in fruit samples from all the markets, Penicillium notatum had the least prevalence of 7.3% and occurred both in Jahun Central and Kabala Markets. The mean microbial count ranges were 10 to 40 × 104 CFU/g for Jahun Central Market and 5 to 30 × 104 CFU/g Kabala Market. The presence of toxin producing fungi Aspergillus niger, which are capable of causing food poisoning as well as some bacterial isolates raises concern over public health risks that may be associated with the consumption of spoiled tomato fruits.

Dyes plays an important role in our everyday life. From manufacturing plastics, paints, textile and even pills contain traces of dye used. With the ever-increasing demand for dye with growing world populations, the use of synthetic dyes has grown linearly. Bioremediation of dyes using microorganisms is on the rise. The ability to accurately predict the rate of bioremediation relies upon the gathering of the accurate rate of decolourisation, which is often inaccurately obtained by natural logarithm transformation of the decolourisation process over time. In this instance, a nonlinear regression of the curve needs to be carried out utilising available rate models. Hence, various primary models such as modified Logistic, modified Gompertz, modified logistics, modified Richards, modified Schnute, Baranyi-Roberts, Buchanan-3-phase, von Bertalanffy and the Huang models were utilized to fit the specific decolourisation rate. Several models failed to converge and was omitted and only Huang, Baranyi-Roberts, modified Gompertz, modified Richards and modified Logistics were able to model the data while other models failed to converge and were omitted. The best model based on statistical analysis was Baranyi Roberts with the highest value for Adjusted Coefficient of Determination and the lowest values for RMSE, AICc, HQC and BIC and the closest value to 1.0 for accuracy and bias factors. The Baranyi-Roberts fitted curve was found to conform to normality tests and is adequate to be used to fit the experimental data. The parameters obtained from this exercise can be utilized for further secondary modelling exercise to gleam information on how substrate (dye) affect the rate of decolourisation of the substrate.

Published: June 2023

A bacterium capable of degrading sodium dodecyl sulphate (SDS) isolated from a paddy field water is characterized. In this report, we showed that almost complete degradation of SDS was observed in 6 to 10 days when the bacterium was grown on medium supplemented with SDS ranging from 0.75 to 1.75 g/L while higher concentrations showed partial degradation with no degradation was observed at concentrations higher than 2.0 g/L. The SDS-degrading bacterium was partially identified and provisionally named Pseudomonas sp. strain Maninjau1. We also showed that the presence of metal ions such as silver, copper, cadmium, chromium, lead and mercury inhibit the ability of the bacterium to degrade SDS by 50%. Growth kinetic studies show a correlation coefficient value of 0.99 for the Haldane model indicates it fits the curve while a low correlation coefficient value of 0.67 for the Monod model indicates poor fitting. The specific growth rate μ was discovered to rise as the substrate concentration was increased but it reached a peak value followed by a slow decrease indicating substrate inhibition. The calculated qmax or maximum degradation rate was 0.917 h-1 (95% confidence interval or C.I. from 0.664 to 1.171) while the saturation constant Ks or half velocity constant was 0.178 g/L SDS (95% C.I. from 0.089 to 0.266). The inhibition constant Ki was 0.605 g/L SDS (95% C.I. from 0.358 to 0.941). The very high maximum degradation rate obtained in this study indicates that this bacterium can be an efficient agent for bioremediation of SDS especially in soils.

Synthetic dyes are abundantly used in recent years and mainly consumed in the textile, pharmaceutical, plastic and cosmetic industries. The release of toxic constituents from dyes give adverse effect on human health and marine life. In textile industries, large amount of dye discharged into the wastewater and eventually to the aquatic system are mainly came from the critical step of dyeing and finishing processes in textile. The be able to precisely forecast the rate of bioremediation, depends on the gathering of precise rate of decolourisation, and this can be inaccurately acquired by natural logarithm transformation of the decolourisation process over time. In cases like this, a nonlinear regression of the curve must be performed making use of accessible rate models. Consequently, numerous primary models for example modified Logistic, modified Gompertz, modified logistics, modified Richards, modified Schnute, Baranyi-Roberts, Buchanan-3-phase, von Bertalanffy and the Huang models were utilized to fit the specific decolourisation rate. Several models did not converge and was disregarded and only Huang, Baranyi-Roberts, modified Gompertz, modified Richards and modified Logistics could actually model the data. The very best model according to statistical analysis was Baranyi Roberts with the highest value for Adjusted Coefficient of Determination and the lowest values for RMSE, AICc, HQC and BIC and the closest value to 1.0 for accuracy and bias factors. The Baranyi-Roberts fitted curve was discovered to conform to normality tests and is satisfactory to be used to fit the experimental data. The parameters extracted from this exercise may be used for additional secondary modelling training to gleam information about how substrate (dye) impact the rate of decolourisation of the substrate

Authors: Yılmaz Savaş Tuba , Savaş Abdulhaluk
Published: June 2023

Statement of the problem: The challenge of enhancing the bond between zirconia and resin remains, and the efforts continue to determine a simple method for achieving a durable bond.

Objective: This study aimed to evaluate the effect of different surface conditioning strategies on the bond strength between zirconia and resin ce-ment.

Materials & Methods: Forty zirconia specimens (Lava Plus) were fabricated and divided into four groups: control (no surface treatment), pri-mer application (Z-Prime Plus), experimental acid (H2O:HF:H2O2) applica-tion, and the combination of the acid and primer application (n=10). A dual-cure resin cement (RelyX Ultimate) was applied over the zirconia specimens. Shear bond strength tests were conducted using a universal testing machine with a cross-head speed of 1 mm/min. The results were analyzed using one-way ANOVA followed by Tukey's post hoc test within the 95% confidence interval.

Results: The results of the one-way ANOVA showed that acid appli-cation alone (22.99 ± 2.49 MPa) and acid and primer application (25.24 ± 3.19 MPa) had significantly higher bond strength than the primer (18.87 ± 3.13 MPa) and control (14.91 ± 3.72 MPa) groups (P<0.05). However, there was no significant difference between the acid group and acid and primer combination group (P=0.396). The control group had the lowest bond strength in all test groups (P<0.05).

Conclusions: Experimental acid treatment alone or in combination with primer application could be effective in improving the bond strength.

Published: June 2023

Statement of the problem: The bonding between the resin cement and zirconia still needs to be improved and the effect of the experimental acid application duration on the resin bond strength with zirconia is unk-nown.

Objective: This study aimed to investigate the effect of different acid application times on the shear bond strength between zirconia and dual-cure resin cement.

Materials & Methods: A total of 50 zirconia disks were prepared in 2 mm thickness and randomly divided into five treatment groups: control (no treatment was applied), 30 seconds HF:H2O:H2O2 acid application group, 60 seconds HF:H2O:H2O2 acid application group, 90 seconds HF:H2O:H2O2 acid application group, and 120 seconds HF:H2O:H2O2 acid application group. Then a dual-cure resin cement was applied over the 3 mm diameter and 3 mm thickness of the zirconia specimens. The speci-mens were immersed in distilled water and maintained at a temperature of 37°C for a duration of 24 hours. The shear bond strength tests were perfor-med using a universal testing machine with a force of 1 mm/min until the fracture occurs, and the data were analyzed using one-way ANOVA and Tukey's post-hoc test.

Results: The highest mean shear bond strength was found in the 90 seconds acid application group, which was significantly higher than the control and 30 seconds acid application groups (P<0.05). However, the 60- and 120 seconds acid application groups showed similar shear bond strength values with the control, 30- and 90 seconds acid application groups (P>0.05).

Conclusions: The use of a 60-, 90- and 120 seconds acid application can improve the bond strength between zirconia and resin cement. However, caution should be taken when using this acid due to its potential toxicity and hazards.

Published: June 2023

Statement of the problem: For successful endodontic treatment, mechanical cleaning and chemical irrigation can be used together. Since the-re is not yet a single solution sufficient for both root canal cleaning alone, combined use of irrigants is recommended for the synergistic effect. Poly-hexanide (PHMB), boric acid, phytic acid, peracetic acid, and hypochlorous acid are relatively new alternative endodontic irrigation solutions and there are no studies in the literature on the combined use of alternative solutions.

Objective: This study aimed to evaluate the interactions that would result from applying PHMB as a substitute for CHX following alternative in-termediate irrigation solutions that might be utili-zed with NaOCl.

Materials & Methods: Eight microtubes were used for this study. 0.5ml of 5%NaOCl was placed in each microtube first, the microtubes were divided into two groups as the final product CHX and Polyhexanide, and the two groups were divided into four groups with different irrigants in themselves. The study was conducted at room temperature and the images of the mixtures were photographed at 1 min, 10 min, 20 min, 30 min, and 1 hour. Groups; G1: NaOCl+ 1%Phytic acid +0.1%Polyhexanide, G2: NaOCl+ 0.02%Hypochlorous acid +0.1%Polyhexanide, G3: NaOCl+ 2% Peracetic acid +0.1%Polyhexanide, G4: NaOCl+ 5% Boric acid +0.1%Polyhexanide, G5: NaOCl+ Phytic acid+ 2%CHX, G6: NaOCl+ 0.02%Hypochlorous acid +2%CHX, G7: NaOCl+ 2% Peracetic acid+2%CHX, G8: NaOCl+ 5% Boric acid + 2%CHX.

Results: White or brown precipitates occurred as soon as the soluti-ons were applied to all of the CHX groups; milky-white precipitate was only seen in the Polyhexanide group's Phytic acid-added group. After 5 minutes, air bubbles were seen in the Polyhexanide group that had Peracetic acid ad-ded, whereas the CHX group had an increase in brown precipitates.

Conclusions: Considering the current research conditions, In clinical practice, the administration of Polyhexanite as the last irrigant and the com-bination of NaOCl with boric acid or hypochlorous acid can be advised.

In many communication systems, turbo coding Techniques for Encoding and Decoding are employed to repair errors. As compared to other error correction codes, turbo codes provide great error correcting capabilities. For the implementation of the Turbo decoder, a Very Large Scale Integration (VLSI) architecture is suggested in this study. The Maximum-a-Posteriori (MAP) algorithm is employed at the decoder side, where soft-in-soft-out decoders, interleaves, and deinterleavers are all used. The usage of the MAP algorithm reduces the quantity of iterations necessary to decode the information bits being transferred. This research employs a system for the encoder component that consists of two recursive convolutional encoders and a pseudorandom interleaver on the encoder side. Tools from Octave and Xilinx Vivado are used for the Turbo encoding and decoding. The system is synthesised and implemented using a specialised integrated circuit.

In order to manage the speed of brushless DC (BLDC) motors, this research presents a novel hybrid control method that simultaneously regulates the DC bus voltage of the inverter and the BLDC motor reference current. A fractional-order PID (FOPID) controller manages the BLDC motor reference current, and a fuzzy logic controller manages the inverter DC bus voltage. A modified harmony search (HS) metaheuristic technique is developed for adjusting the FOPID controller parameters. Three separate working scenarios—no load, varying load, and varying speed—are used to test the motor's capabilities. Run the proposed controller at a high speed to verify its efficacy. The suggested hybrid control method has also been put to the test. weighed against FOPID and fuzzy-based speed control techniques The outcomes demonstrate the effectiveness of the suggested control. approach enables more accurate speed control over a wide region.

Minor architectures, micro empires: women and the production of domestic space on the nineteenth-century Pacific 'Frontier'
Authors: Vujosevic Tijana
Published: June 2023

This essay looks at three portraits of women as homemakers on the Pacific Northeast following British Columbia's 1873 accession to the Dominion of Canada, when colonial relationships were buttressed by legal and administrative means, and ideas and practices of the home were central to the spread of Victorian moral norms on the Canadian ‘frontier’. Colonial spatial notions of interiority and exteriority, relationships to the site, and object-regimes were negotiated in this intimate microcosm.
The work of space-making that ‘frontier’ women presented in minor pictorial and literary genres was in itself a ‘minor architecture’ about finished form, or objecthood, and the perpetual negotiation of contradictory and unstable imperial spatial relationships which required reworking, reproducing, and redefining. These minor architectures' histories on the ‘frontier’ reveal architecture's power to weave hegemonic values into the very fabric of existence, as well as the fundamental interconnectedness of the identity of settler women and their labour.

There are different methods for hydrogen production, among which thermo-chemical cycles are particularly important. One of the most common thermochemical cycles is the copper-chlorine cycle. In this cycle, the water electrolysis process takes place during a thermo-chemical reaction, and copper chlorine is used as a thermochemical reaction intermediate. This cycle requires two factors to produce hydrogen: A heat source with a temperature of about 520 oC and electricity. For this reason, it is possible to use the hot waste gases of industries or parabolic through collector and heliostat field to provide its heat. To supply electricity for this cycle, various alternatives from the power grid and wind turbine to heat recovery in cycles that use low-temperature energy sources are considered. In this article, the integration of the copper-chlorine cycle with power generation systems has been discussed and investigated from the perspective of energy, exergy, and economics. This review is divided into two general parts using renewable and non-renewable resources. At the beginning of this article, various methods of hydrogen production focusing on the copper-chlorine cycle have been briefly discussed. In the following, the way this cycle works is explained along with energy, exergy, and economic equations, and the research done in this direction is explained. Finally, a strategy for how to integrate the copper-chlorine cycle with other systems is described. Studying this article, in addition to giving a better attitude in the field of integrating this cycle with other plants, is similar to a guideline for using the cycle along with other systems for better productivity. The conducted investigations showed that the recovery of hot industrial exhaust gas as a source of heat for the Cu-Cl cycle has a high potential for saving energy consumption and reducing environmental pollutants. To produce the required electricity, it is recommended to use cycles that work with a low-temperature energy source, such as the organic Rankine cycle and Kalina cycles. Also, if renewable energy sources are used, it is recommended to use parabolic through collectors and heliostats to produce the required heat. As in the case of non-renewable energy sources, cycles with low-temperature energy sources can be used.

Küreselleşmenin artması ve değişen dünya ekonomisiyle beraber girişimciler yönlerini dış ticarete çevirmektedirler. Bu bağlamda ihracat yapan uluslararası girişimcilerin uluslararasılaşma süreçlerinden geçerken hangi yolları izledikleri araştırmanın konusunu oluşturmaktadır. Türkiye’de uluslararası girişimcilik alanında gerçekleştirilen çalışmalar az sayıdadır. Alan yazına katkı sağlamak amacıyla, ele alınan araştırma kapsamında ihracat yapan işletmelerin uluslararası girişimcilikte uluslararasılaşma süreçleri incelenecektir. Uluslararası işletmelerin faaliyet alanları ve uluslararası girişimciliğin gelişim olanaklarını belirlemek için çeşitli modeller ortaya koyulmaktadır. Bu modeller aşama yaklaşımları, küresel doğanlar yaklaşımları ve ağ yaklaşımlarıdır.

Zengin veri elde etme imkânı açısından nitel araştırma perspektifi benimsenmiştir. Yeni araştırma alanlarında amaç keşifsel bulgular aracılığıyla mevcut bilgi birikimine katkı sağlayarak alanda gelecekte gerçekleştirilecek araştırmalara teorik bakış açıları geliştirmektir. Veri toplama yöntemi olarak yapılandırılmamış ve yarı yapılandırılmış sorulardan oluşan derinlemesine mülakat tekniğinden yararlanılmıştır. Araştırma yapılırken il bazlı popülasyon tercih edilmektedir. Bursa ve Karabük illerinin seçilmesi zıt ekolojiler olmasıdır. Karabük’te tam sayım örnekleme kullanılırken Bursa’da maksimum çeşitlilik örneklemesi kullanılmıştır.

Nitel yöntemler, kolektif faaliyeti ve durumsal ayrıntıları ortaya çıkarmaya ve teorik kavramları nüanslı veriler aracılığıyla doğrulamaya izin verir. Sonuç olarak, uluslararası girişimcilik teorisinde uluslararasılaşma süreçlerinin yeni, sistematik bir kavramsallaştırmasını geliştirilmektedir. Veri analizinde anlamlı ve fikir grupları ile temaların tanımlanmasına, analiz edilmesine ve raporlanmasına olanak tanıyan veri analiz biçimi olan tematik veri analizi kullanılmaktadır.

Korumacılık ve serbest ticaret politikalarının Dünya ticaretinin boyutu ve kapsamı üzerinde önemli etkileri vardır. Ülkelerin kendi ekonomilerini ve kırılgan sektörlerini korumak için dış ticareti kısıtlamak adına aldıkları önlemler ile bunun tam karşısında ticaret engellerini kaldırarak, diğer ülkelerle aralarındaki ticareti kolaylaştırmayı amaçlayan politikalar uygulamalarının küresel ticaret hacmini ve ülkelerin milli gelir düzeylerini nasıl etkilediği konusu önemli bir tartışma alanıdır. Bu çalışmada bu tartışmalı alandaki konular kavramsal olarak ele alınmış ve konu kapsamlı bir literatür incelemesi ile desteklenmiştir. Çalışmanın uygulama bölümünde ise ABD örneği üzerinden panel çekim modeli test edilmiştir. 2000-2019 dönemi için ABD’nin ticaret hacmi olarak en çok dış ticaret yaptığı ve/veya serbest ticaret anlaşması akdettiği 43 ülke üzerinden panel çekim modeli kurulmuştur. Rastsal etkiler modeli yaklaşımının uygulandığı panel regresyon analizleri EGLS (yatay kesit ağırlıklı) yöntemiyle Eviews 12 ekonometri programı üzerinden gerçekleştirilmiş olup, söz konusu dönem için panel çekim modeli doğrulanmıştır.

Shopping Lifestyle merupakan ekspresi tentang lifestyle dalam berbelanja yang mencerminkan perbedaan status sosial. Cara berbelanja yang cenderung mencerminkan status, martabat, dan kebiasaan. Shopping lifestyle menunjukkan cara yang dipilih oleh seseorang untuk mengalokasikan pendapatan, baik dari segi alokasi dana untuk berbagai produk dan layanan, serta alternatif-alternatif tertentu dalam pembedaan kategori yang sama. Mahasiswa yang berada dalam rentang usia remaja akhir merupakan individu yang dinamis serta memiliki banyak sekali peluang. Terlebih lagi di rentang usia ini, tak jarang mahasiswa yang sudah terjun ke dalam dunia kerja, sehingga sudah memiliki penghasilan yang memungkinkan mahasiswa tersebut dapat memenuhi kebutuhan hidup dan mewujudkan keinginan. Usia yang masih muda belum membuat mahasiswa dihadapkan pada permasalahan kebutuhan hidup seperti orang dewasa, sehingga preverensi pemenuhan keinginannya lebih banyak dibandingkan pemenuhan kebutuhan. Perilaku inilah yang kemudian memungkinkan mahasiswa menjadi salah satu pemeran dalam Shopping Lifestyle di masyarakat. Financial Literacy/ pemahaman keuangan harus dipahami mahasiswa dengan baik, sehingga mahasiswa mampu mengalokasikan dan mengatur dengan bijaksana  pendapatannya sehingga tidak hanya habis hanya untuk memenuhi keinginan semata.
