This article examines the distribution of nitrogen-transforming bacteria in an artificial reservoir (pond) populated with aquatic higher plants of common reed (Phragmites australis) and cattail (Typha) for treating swine wastewater. In the pond occupied by Phragmites australis, 7 strains of ammonium oxidising and 14 denitrifying bacteria were identified, while, in the pond occupied by Typha, 6 strains of ammonium oxidising and 19 denitrifying bacteria were distinguished. A comparative analysis of bacterial count at various sampling points revealed their decrease along the artificial pond. Most of the bacteria strains oxidising ammonium were identified in the samples collected from the surface layer of the pond, while denitrifying bacteria dominated the bottom layer. The isolated microorganisms identified by 16S rRNA sequencing belonged to the genus Pantoea, Enterobacter and Bacillus. An artificial pond having aquatic higher plants is characterised by a diverse microbiota, whose composition strongly depends on the wastewater source rather than on the cultivated plant species. The ammonia transformation and denitrification capacity of isolated bacterial strains was determined. The highest conversion efficiency of ammonia (up to 56%) was observed for Enterobacter cloacae bacteria isolated from the surface layer of the pond. Denitrifying bacteria sampled from the bottom layer allowed for the reduction in nitrate content from 20 to 10 mg/L in 72 h. The obtained results confirm the role of bacteria in the treatment of wastewater against nitrogen-containing pollutants, with the average efficiency of removal of inorganic nitrogen compounds being 50%.

Published: January 2023

The ever-increasing volumes of gold mining in the Republic of Uzbekistan requires an increase in the cost of water resources. However, the subdivisions of the Navoi MMC are located in the arid, lowwater areas with high (40–80 %) and extreme (more than 80 %) water shortages. Therefore, the problem of water supply, water disposal and improvement of the closed water circulation system with the use of innovative biotechnological solutions is acute for the enterprise. The purpose of this work is to summarize current data on the use of wastewater bioremediation technologies at mining enterprises and to assess the prospects for using this technology by Navoi Mining and Metallurgical Company. The article summarizes the data on the use of bioremediation at mining enterprises in Russia and other countries and data obtained from our own experimental studies of the cleansing functions of plants in Uzbekistan. These studies were carried out under the laboratory modeling conditions using wastewater from tailing ponds GMZ-2 and GMZ-3 NMMC. The cleansing functions of the plants of the Zarafshan river valley were studied: eichornia, pistia, azoles and duckweed. It was found that eichornia has the highest cleansing potential: due to the high activity of the cyanidutilizing enzyme beta-cyanoalanine synthase, it accumulates metals and metabolizes cyanides. Pistia and azola have proven to be tolerant to high salinity levels and need to be adapted by adding organic matter, including sheep manure. The next stage is semi-industrial testing in a tailing dump and development of technical regulations.
Risks of emergencies in the Far North of Krasnoyarsk region
Authors: Sokolova K. A.
Published: January 2023

The issue of security insurance in the Far North of the Russian Federation is being annually solved. The paper presents the calculation of emergency risks for the Far North of Krasnoyarsk region. The initial data for the calculation are the geographical characteristics and climatic features of the Far North of Krasnoyarsk region, which may entail the risk of emergencies and incidents; hazard categories of natural and man-made emergencies that may occur in the territory; the number of deaths caused by emergencies and incidents over the past five years. The most common cause of emergency in the northern territories of the region and in the circumpolar zone was identified. It is man-made fires. The number of fires in the industrial sector of the polar regions is much higher than in other regions. The paper suggests ways to reduce the unacceptable level of emergency risks. It seems that these measures will make the northern territories safer and more accessible to the population.
Chemoradiation therapy for localized colorectal cancer: a view from the outside
Authors: Akhmetzyanov F. Sh. , Egorov V. I. , Abdulganieva G. R.
Published: January 2023

Background. Colorectal cancer is among the most lethal and prevalent malignances in the world. The management of localized colorectal cancer is highly debated. Surgical resection of the rectum, such as total mesenteric excision (TME) is usually associated with significant morbidity and mortality. The integration of various chemotherapy options into the standard treatment of localized rectal cancer could potentially enhance the tumor control with a subsequent reduction in the frequency of recurrence, thus improving overall and disease-free survival. Moreover, there are categories of patients for whom surgical treatment is contraindicated and chemotherapy will be more useful for them. Although rectal cancer is predominantly a disease of older patients, current guidelines do not incorporate optimal treatment recommendations for elderly patients with comorbidities; therefore this issue remains a matter of debate.

Aim. We aimed to consider alternative approaches to the treatment of localized rectal cancer and the management of selected patients with this diagnosis.

Material and Methods. We searched for publications in the Pubmed, eLibrary databases and up-to-date information on the basis of world cancer associations.

Conclusions. Comparison of surgery with concurrent chemoradiotherapy for localized rectal cancer showed that in some cases neoadjuvant therapy can be useful and successful, acting as an ideal alternative. However, this approach may be suitable for selected patients who meet certain criteria. In addition, a follow-up care after treatment should include a specific range of diagnostic imaging tests.

Background. During the COVID-19 pandemic, annual adult check-ups have been postponed, resulting in cancer screening disruption.

The aim of the study was to evaluate changes in the incidence and stage distribution of malignancies included in the screening program during the COVID-19 pandemic using the Arkhangelsk Regional Cancer Registry (ARRC).

Material and Methods. We assessed the changes of the incidence rates and stage distribution for the colon, rectum, lung, breast, cervix, uterine body, ovary, prostate and kidney cancers over the periods 2018–19 and 2020–21. Results. A total of 12354 cases with 9 cancers were selected: 6680 for the period 2018–19 and 5674 (-15.1 %) for the period 2020-21. The most significant decrease in crude and age-standardized incidence rates was registered in patients with lung (-18.0–18.1 %), rectum (-25.1–25.9 %) and cervix (-33.6–36.9 %) cancers, p<0.001. The decrease was not signifcant in patients with breast, uterine body, and kidney cancers. The proportion of patients with stage I decreased in lung cancer (-20.0 %, from 14.8 % to 11.8 %), rectum (-20.2 %, from 20.9 % to 16.7 %), and uterine cervix (-37.1 %, from 53.2 % to 33.5 %). In prostate and kidney cancers, the proportion of patients with stage I increased by 30 % (from 19.5 % to 25.4 %) and 17.6 % (from 45.9 % to 54.0 %), respectively. A signifcant reduction in the proportion of early stages during the COVID-19 pandemic was observed in lung and cervical cancer. Conclusion Postponed health checkups due to COVID-19 pandemic disruptions have led to substantial reductions in new cancers being diagnosed, mainly for cervical, lung, colon and rectal cancers. No signifcant changes were observed for other cancers. Further analysis of mortality and survival of cancer patients is required. Key words: health checkup, cancer screening, COVID-19 pandemic, cancer incidence, stage distribution>˂0.001. The decrease was not significant in patients with breast, uterine body, and kidney cancers. The proportion of patients with stage I decreased in lung cancer (-20.0 %, from 14.8 % to 11.8 %), rectum (-20.2 %, from 20.9 % to 16.7 %), and uterine cervix (-37.1 %, from 53.2 % to 33.5 %). In prostate and kidney cancers, the proportion of patients with stage I increased by 30 % (from 19.5 % to 25.4 %) and 17.6 % (from 45.9 % to 54.0 %), respectively. A significant reduction in the proportion of early stages during the COVID-19 pandemic was observed in lung and cervical cancer.

Conclusion. Postponed health checkups due to COVID-19 pandemic disruptions have led to substantial reductions in new cancers being diagnosed, mainly for cervical, lung, colon and rectal cancers. No significant changes were observed for other cancers. Further analysis of mortality and survival of cancer patients is required.

Araştırma kapsamında Türkiye’ye Haziran 2021-Eylül 2021 tarihleri arasında yurtdışından seyahat eden turistler evreni oluşturmaktadır. Evrenin tamamına zaman, maliyet ve ziyaretçilerin tamamına ulaşılması bakımından mümkün olmadığı için örneklem alma yoluna gidilmiştir. Araştırmada toplamda 234 turiste kolayda örneklem metodu kullanılarak anket formu doldurtulmuştur. Araştırmada çekici seyahat motivasyon ölçeği kullanılmış olup, ölçek; kültürel miras, etkinlik & festivaller ve doğal miras olmak üzere üç alt faktör olarak incelenmiştir. Veri analizi sürecinde veriler normal dağılım gösterdiği için bağımsız örneklemler için t testi ve tek yönlü varyans (Anova) analizi kullanılmıştır. Araştırma sonuçlarına göre turistlerin cinsiyetleri ile çekici seyahat motivasyonu faktörleri arasında anlamlı bir farklılık bulunamazken, medeni durumları ile arasında anlamlı bir farklılık tespit edilmiştir. Evlilerin çekici seyahat motivasyonları bekarlardan daha yüksek çıkmıştır. Ayrıca turistlerden 65 yaş ve üzerinde olanların diğer yaş gruplarından motivasyonları daha düşük çıkmıştır. Turistlerden gelir algısı çok düşük olanların gelir algısı orta ve çok yüksek olanlardan çekici seyahat motivasyonları daha düşük çıkmıştır. Ancak turistlerin eğitim düzeyleri ile çekici seyahat motivasyon faktörleri arasında istatistiksel olarak anlamlı bir farklılığa rastlanılmamıştır.

Hem ekonomiye hem de istihdama katkısından dolayı ülkemizde ve dünyada oldukça önemli bir konumda yer yiyecek içecek işletmeleri gıda atıklarının oluştuğu yerler arasında öne çıkmaktadır. Gıda atıklarının meydana gelmesi noktasında etkili olan faktörler arasında insanların yiyeceklere karşı sergiledikleri neofobi, neofili ve çeşitlilik arayışı davranışları etkili olabilmektedir. Neofobi, neofili ve çeşitlilik arayışı ile gıda atık davranışları arasındaki ilişkilerin araştırılması çalışmanın amacını oluşturmaktadır. Bu doğrultuda 495 kişiden anket formu ile veri toplanmıştır. Elde edilen genel bulguların yanı sıra gıda atık davranışlarının cinsiyete ve medeni duruma göre farklılaştığı tespit edilmiştir. Ayrıca neofili ve çeşitlilik arayışı ile gıda atık davranışları arasında olumlu ilişkiler ortaya çıkmış; neofili eğiliminin gıda atık davranışları üzerinde olumlu etkisi görülmüştür. Buna göre neofili ve çeşitlilik arayışı yüksek olan katılımcıların daha az gıda atığı bırakma eğiliminde olduğu sonucuna ulaşılmıştır. Sonuçlar ışığında; bu konuda yapılması planlanan ileriki çalışmalarda daha büyük veya sosyal ve ekonomik açıdan mevcut çalışmadan farklı bir örneklem grubu tercih edilebileceği, kültürlerarası çalışma yürütülerek karşılaştırma yapılabileceği önerilmektedir.

Authors: ARAS Sercan
Published: January 2023

Turizm ve açık alan rekreasyon faaliyetleri, çok sayıda insanın rahatlamak, eğlenmek, keşfetmek, gezmek gibi birçok nedenle tercih ettiği ve bunun sonucunda faaliyetlerin yapıldığı ülkeye ekonomik gelir sağladığı hizmetlerdir. İklim değişikliği, tüm dünyayı etkileyen ve ilgilendiren son yılların en önemli konularından biridir. İklim değişikliğinin yaratmış olduğu etkiler birçok sektör üzerinde olduğu gibi turizm sektörü üzerinde de hissedilmektedir. Turizm ve açık alan rekreasyon faaliyetlerinin çevre ve doğa kaynaklı olması, bu etkinin daha fazla hissedilmesine neden olmaktadır. Buna rağmen, iklim değişikliği, turizm ve açık alan rekreasyonu ilişkisi ile ilgili çalışmaların literatürde sınırlı olduğu görülmektedir. Buradan hareketle, araştırmada, iklim değişikliğinin turizm ve açık alan rekreasyonu üzerindeki etkisinin incelenmesi ve tartışılması amaçlanmıştır. Çalışmada literatür incelemesi yapılmış olup ayrıca ikincil verilerden yararlanılmıştır. Çalışmanın sonucunda, iklim değişikliğinin turizm ve açık alan rekreasyonunu farklı açılardan etkilediği görülmüştür. Bu etkilerin ilerleyen yıllarda turist akışını farklı coğrafyalara doğru yönlendirebileceği belirlenmiştir. Küresel ısınmayla birlikte özellikle Kuzey Avrupa, Kanada ve Rusya gibi ülkelerde aktivite gün sayısının artışıyla beraber turizmin ve açık alan rekreasyonunun daha önemli hale geleceği düşünülmektedir. Diğer yandan iklim değişikliğinin etkisiyle sıcak hava dalgası ve kasırga gibi aşırı hava olaylarının artışı, turizm altyapısının zarar görmesine ve turistlerin can güvenliğinin tehdidine neden olabilmektedir. Kaliteli turizm ve açık alan rekreasyonu için iklim değişikliğinin potansiyel etkilerinin hafifletilmesi ve bu etkilere uyum sağlanabilmesi amacıyla tüm paydaşların katılımıyla stratejilerin oluşturulması gerekmektedir.
Olumsuz Deneyimler Unutulmaz Gastronomik Deneyimler Ölçeğinin (UGD) Bir Boyutu Olmalı Mı Farklı Kültürler Üzerinde Bir Doğrulama Çalışması
Authors: YÖNEL Duygu , ÇAKIR Onur
Published: January 2023

Çok boyutlu bir yapıya sahip olan unutulmaz gastronomik deneyimlerin (UGD) nasıl ölçülmesi gerektiğine dair alanyazında farklı görüşler bulunmaktadır. En büyük görüş ayrılığı olumsuz deneyimlerin UGD ölçeğinin bir parçası olup olmaması gerektiğine yöneliktir. Bu çalışmada UGD’yi ölçmek için Adongo, Anuga & Dayour (2015) tarafından geliştirilen ve olumsuz deneyimleri de kapsayan güncel bir ölçek olan unutulmaz gastronomik deneyimler ölçeğinin geçerli ve güvenilir bir ölçek olup olmadığı doğrulanması ve olumsuz deneyimler boyutunun UGD’nin bir parçası olup olmadığının tespit edilmesi amaçlanmıştır. Bu amaçla dört farklı milletten İzmir ilini ziyaret eden 517 turist üzerinde gerçekleştirilen anket çalışması ile veriler toplanmış olup görünüş ve kapsam geçerliliği, yapı geçerliliği, ayırt edici geçerlilik, tahmin geçerliliği ve güvenilirliği test edilmiştir. Tahmin geçerliliği alanyazında en sık kullanılan değişkenler olan destinasyon memnuniyeti ve davranışsal niyetler ile ilişkilendirilerek test edilmiştir. Araştırma sonucunda olumsuz deneyimlerin UGD ölçeğinin bir alt boyutu olarak ele alınmaması ve olumsuz gastronomik deneyimlerin genel destinasyon memnuniyetini olumsuz etkileyen bağımsız bir değişken olarak ele alınması gerektiği tespit edilmiştir.

Published: January 2023

La pandemia del COVID-19 trajo repercusiones en distintos niveles y generó nuevos aprendizajes que no formaban parte del currículo escolar, pero se reconocen como necesarios para ayudar a los estudiantes a comprender la situación que viven y gestionar su agencia. Precisamente, debido a la necesidad de informar y educar sobre la prevención y el cuidado, se incorpora en el currículo escolar la pandemia del COVID-19 como un contenido emergente, vinculado con una problemática que sobreviene sin más, gracias a la cual es necesario revisar y cuestionar de forma crítica (Anguita et al., 2010; Dego y Ferraz, 2008). Este estudio cualitativo busca explorar las percepciones docentes sobre la incorporación de la pandemia del COVID-19, como contenido emergente en la implementación del currículo y los aportes de dicho contenido en los estudiantes y sus familias, durante la educación remota (abril 2020 y julio 2021). Se entrevistaron a dieciocho docentes de dos escuelas del Cercado de Lima. La  pandemia representó un contenido emergente y estructurador, alrededor del cual se vincularon diversos contenidos conceptuales, prácticas, hábitos y actitudes, incorporados a través de la programación de experiencias significativas, la integración de áreas curriculares, en actividades permanentes y de tutoría. Los docentes perciben un currículo flexible que les permitió adaptar la propuesta oficial a la realidad y necesidades de sus estudiantes. La pandemia aportó aprendizajes centrados en la práctica de nuevos hábitos de cuidado personal y de salud, así como la importancia de valores como la solidaridad y resiliencia, entre otros.

Accrualls and systematic risk in Brazilian companies
Authors: Oliveira Junior José Luciano de , Nossa Valcemiro , Nossa Silvania Neris , Oliveira Edvan Soares
Published: January 2023

Purpose: The objective of this study was to investigate whether the systematic risk of companies listed on the Brazilian Stock Exchange (B3) is affected by the quality of accounting information. Additionally, it was verified if the systematic risk was affected differently after the mandatory adoption of IFRS in Brazil.

Methodology: The sample comprised all companies with observations listed on the Brazilian stock exchange (B3) from 2005 to 2021. Empirical research was carried out with descriptive analysis and a quantitative approach. Data were estimated in a panel with fixed effects. The total value of the accruals of Dechow and Dichev (2002) and Jones (1991) were used as measures of the quality of accounting information. The systematic risk measures were estimated using market models and three factors by Fama and French (1993).

Results: In general, companies that have higher quality accounting information are able to reduce information asymmetry problems, which increase systematic risk, thus, having higher quality in this information reduces the risk to the investor.

Contributions of the Study: The results of this paper bring practical contributions to the market and investors, who can feel more secure due to clarity and confidence in the information. Even with the adoption of IFRS in Brazil, the main conclusion of our research is that it actually contributes to the quality of information being converted into lower risks.

Authors: Liu Zhihan , He Yan , Ma Xia
Published: January 2023

γ-Polyglutamic acid is a kind of biomaterial and environmentally friendly polymer material
with the characteristics of water solubility and good biocompatibility. It has a wide range of applications
in medicine, food, cosmetics and other fields. This article reviews the preparation, characterization
and medical applications of γ-polyglutamic acid nanoparticles. Nanoparticles prepared by using γ-
polyglutamic acid not only had the traditional advantages of enhancing drug stability and slow-release
effect, but also were simple to prepare without any biological toxicity. The current methods of nanoparticle
preparation mainly include the ion gel method and solvent exchange method, which use the total
electrostatic force, van der Waals force, hydrophobic interaction force and hydrogen bond force between
molecules to embed materials with different characteristics. At present, there are more and more
studies on the use of γ-polyglutamic acid to encapsulate drugs, and the research on the mechanism of its
encapsulation and sustained release has gradually matured. The development and application of polyglutamic
acid nanoparticles have broad prospects.

Mixed matrix membranes are thought to have the ability to separate gases. The current research investigates the isolation of CO2 from methane (CH4) and nitrogen (N2) using a mixed matrix membrane. Bio-MOF-11 was combined with polyether sulfone to establish a membrane (PES). Experiments were carried out to determine the efficiency of the established membrane. Results showed that the Lewis basic sites present in Bio-MOF-11, which have a higher affinity for CO2, increase the permeability and selectivity of pristine polyether sulfone.

The production of coconut and durian means that it will produce a lot of waste from its shell. Indonesia is a country that produces a lot of them. The coconut shell (CS) and durian fruit peel (DFP) can be converted to briquette as new fuel from biomass.  The objective of this research is to obtain the calorific briquette properties of CS and DFP using Differential Scanning Calorimetry (DSC).  The material composition consist of 10 % and 15 % of starch for each CS and DFP. Thermal treatment was carried out in the temperature range of 28 °C to 600 °C at 5.4 °C/min. The addition of starch causes the heating temperature since it has thermoplastic properties. Additionally, it is difficult to burn and carries a lot of water so that the heat generated is used to evaporate the water first of all in the briquettes. The recommended material is CS with 10 % mass of starch. The optimum temperature reached was 578.97 °C with an enthalpy value of 0.42 J/g.

In this study, commercial titanium rod was treated by equal-channel angular pressing (ECAP) with Bc route and two passes. This treatment was then evaluated by means of x-ray diffraction (XRD) analytical method. The evaluation was concentrated in crystal structure and residual lattice strain investigations. There were no significant crystal structure change before and after ECAPed. However, there were significant change in residual lattice strain after ECAPed. Before ECAPed, this titanium rod consisted of two lattice strains i.e. 0.0052 and 0.0009. After ECAPed, longitudinal lattice strain reduced from 0.0052 to 0.0036 after first pass and reduced again to 0.0025 after two passes. Meanwhile, shear lattice strain changed from 0.0009 to 0.0032 after first pass and was then annihilated after two passes. These results show that ECAP treatment can reduce and eliminate lattice strains on titanium rod. This study also shows that the reduction of lattice strains implicates to the increasing of its hardness value.

Mechanical vibration is a potential source of micro-electrical energy harvesting mechanisms for micro electrical power supply for IoT system networks, wireless and sensors where the power requirements are relatively lower and available independently. In this study, the characteristics of the cylinder vibration response as a trigger for energy harvesting from flow-induced vibrations at various air velocities were investigated experimentally in a wind tunnel test section. Harvesting of micro power from cylinder’s motion by using galfenol (Fe-Ga) material was also investigated simultaneously. The maximum cylinder’s vibration response was obtained by using the plain cylinder model. Cylinder taper variation reduce the maximum vibration response. The position of the major (D) and minor (d) (or inverse position) diameters also affects the vibration response. However, tapering the cylinder reduces the onset vibration with respect to the flow velocity. The frequency of the vortex (Strouhal, St) ranges from 0.25 to 0.12. The minor diameter of the tapered cylinder has the effect on decreasing the vibration response and tends to be stationary. Minor diameter reduction reduces the potential for vibration to the structure. The maximum power generated by the test model is about 8.5 mW with the power RMS value of 2.3 mW and power coefficient about 4%.

Orange-fleshed sweet potato (Ipomoea batatas) carotenoids were encapsulated in maltodextrin and whey protein concentrates by spray-drying to promote dispersibility in water and looked for the best encapsulant concentration in both encapsulants. The moisture content, wettability, hygroscopicity, color characterization, cold water solubility, and encapsulation efficiency were analyzed for encapsulant concentration of 10%, 20%, and 30% (w/v). The encapsulant concentration of 20% showed the best result with 6.09% moisture content, 11.07 hygroscopicity, 51 s wetting time, 94.50% cold water solubility, and 81.52% encapsulation efficiency for maltodextrin encapsulant. While whey protein concentrates encapsulant gave the result of 6.35% moisture content, 12.44% hygroscopicity, 148.8 s wetting time, 93.13% cold water solubility, and 82.02% encapsulation efficiency. The diffractogram from XRD showed that microcapsule had the amorphous phase dominant and indicated high solubility in water matrix. The microcapsule using maltodextrin encapsulant has smoother and more spherical morphology than microcapsule using whey protein concentrate encapsulant. The color characterization of 30% was lighter, less red, and less yellow than the others based on L*, a*, and b* value respectively. The carotenoid with 20% encapsulant concentration was well encapsulated enough and the addition of more than that did not produce significantly better results.

Cold infused technique is one of the brewing methods that potentially able to preserve coffee leaf tea functional properties. It is mainly attributed to the absence of heat treatment during its processes. However, without involving heat, the sensory quality of cold brewing tea is generally weak. To overcome this issue, it was hypothesized that water quality used for the brewing is important to govern optimum functional properties of Robusta coffee leaf tea and at the same time to maintain its sensory quality. In this current study, Response Surface Methodology (RSM) was applied by implementing Box-Behnken Design (BBD) to optimize both total phenolic content (TPC) and antioxidant activity by modifying length and temperature of cold brewing as well as its water and coffee leaf powder ratio. There were 3 different commercial drinking water used for brewing to represent 3 different hardness level of water. All optimum brewed coffee leaf tea was then sensorially evaluated by Rate All That Apply (RATA) method. It was found that level of water hardness is positively correlated to TPC but negatively correlated to brewing temperature as well as water and coffee leaf powder ratio. It was also found that the higher level of water hardness, both fruity and marine aroma tended to be more intense (p-value<0.05). Meanwhile the lower level of water hardness tended to enhance sweet aroma and astringent mouth-feel (p-value<0.05) of cold infused coffee leaf tea.
