Diagnostic performance of the calcium/phosphate ratio for primary hyperparathyroidism in southwest China
Authors: Yin Mengting , Liu Qianhui , Wang Qingzhong , He Yong , Song Haolan , Nie Xin , Li Guixing
Published: September 2021

Background

The diagnosis of primary hyperparathyroidism (PHPT) remains a challenge because of increased asymptomatic PHPT or patients with normocalcaemic PHPT (NPHPT). In addition, some primary hospitals in China have no equipment to measure parathyroid hormone (PTH) levels. Therefore, an additional, simple, and inexpensive laboratory biochemical marker is urgently needed. The calcium/phosphate (Ca/P) ratio and chloride/phosphate (Cl/P) ratio have been proposed as suitable tools to diagnose PHPT in Europe; however, the Ca/P ratio has never been tested in China. We aimed to conduct a confirmatory study to explore the diagnostic performance of the Ca/P ratio for PHPT in China.

Methods

From January 2015 to December 2020, a total of 155 patients who underwent parathyroidectomy (143 PHPT patients and 12 NPHPT patients) and 153 controls were enrolled in this single-center , retrospective study. Serum calcium, phosphate, parathyroid hormone, 25-hydroxyvitamin vitamin D (25(OH) vitamin D), chloride, alanine transaminase (ALT), aspartate aminotransaminase (AST), estimated glomerular filtration rate (eGFR), and creatinine levels were recorded for all the study participants. Pairwise comparisons were made between groups, and the diagnostic performance of the Ca/P ratio was determined using receiver-operating characteristic (ROC) analysis.

Results

Patients with PHPT had a higher Ca/P ratio than controls (P < 0.001). A Ca/P ratio above 2.94 with a sensitivity of 95.5% and specificity of 98.7% can distinguish PHPT patients from healthy individuals. This index was positively correlated with the PTH level (r = 0.875, P < 0.001).

Conclusion

The Ca/P ratio is an ideal and inexpensive indicator for diagnosing PHPT in China when using a cut-off value of 2.94.

Marcos 1.21-29a: estudio literario y Socio-religioso
Authors: Mena Oreamuno Francisco
Published: September 2021

El artículo estudia el primer relato de exorcismo en el Evangelio según Marcos 1.21-29a. La comparación de ese breve relato con otros textos pertinentes de esa época muestra que Jesús no fue un exorcista y por esta razón nos preguntamos cuál es la mejor forma de entender el tipo social de Jesús. Este tipo de trabajo nos ayuda a ver la Biblia con ojos nuevos y, en consecuencia, modificar muchas premisas que tenemos y que cultivan el fundamentalismo.
La educación religiosa en Costa Rica: Aportes desde la interculturalidad
Authors: Méndez Méndez Jose Mario
Published: September 2021

En Costa Rica se carece de una reflexión sólida sobre el estatuto curricular de la educación religiosa. Si somos un país constitucionalmente multicultural y pluriétnico, resulta necesario asumir la tarea de clarificar el aporte específico de la educación religiosa en el conjunto de la propuesta educativa nacional. Esta tarea implica diálogos y búsquedas en torno a los objetivos, el “objeto de estudio”, los criterios metodológicos, las áreas temáticas a privilegiar, el perfil de la persona docente, los criterios para la evaluación de los aprendizajes y el diálogo con otros componentes curriculares del sistema educativo nacional. Ese trabajo busca ofrecer algunas pistas que, junto a otros aportes, pueden contribuir al replanteamiento curricular de la educación religiosa costarricense desde una perspectiva intercultural.
A Comprehensive Solution Approach for CNC Machine Tool Selection Problem
Authors: Sahin Yusuf , Aydemir Erdal
Published: September 2021

A proper CNC machine selection problem is an important issue for manufacturing companies under competitive market conditions. The selection of an improper machine tool can cause many problems such as production capabilities and productivity indicators considering time and money industrially and practically. In this paper, a comprehensive solution approach is presented for the CNC machine tool selection problem according to the determined criteria. Seven main and thirteen sub-criteria were determined for the evaluation of the seven alternatives. To purify the selection process from subjectivity, instead of a single decision-maker, the opinions of six different experts on the importance of the criteria were taken and evaluated using the Best-Worst method. According to the evaluations, the order of importance of the main criteria has been determined as cost, productivity, flexibility, and dimensions. After the weighting of the criteria, three different ranking methods (GRA, COPRAS, and MULTIMOORA) were preferred due to the high investment costs of the selected alternatives. The findings obtained by solving the problem of selection of the CNC machine are close to those obtained by past researchers. As a result, using the suggested methodology, effective alternative decision-making solutions are obtained.

There are four distinct runs of Chinook Salmon (Oncorhynchus tshawytscha) in the Central Valley, named after their primary adult return times: fall, late-fall, winter, and spring run. Estimating the run-specific composition of juveniles entering and leaving the Sacramento–San Joaquin Delta is crucial for assessing population status and processes that affect juvenile survival through the Delta. Historically, the run of juvenile Chinook Salmon captured in the field has been determined using a length-at-date criteria (LDC); however, LDC run assignments may be inaccurate if there is high overlap in the run-specific timing and size of juveniles entering and leaving the Delta. In this study, we use genetic run assignments to assess the accuracy of LDC at two trawl locations in the Sacramento River (Delta entry) and at Chipps Island (Delta exit). Fin tissues were collected from approximately 7,500 juvenile Chinook Salmon captured in trawl samples between 2007 and 2011. Tissues were analyzed using 21 microsatellites to determine genetic run assignments for individuals, which we compared with LDC run assignments. Across years, there was extensive overlap among the distributions of run-specific fork lengths of genetically identified juveniles, indicating that run compositions based on LDC assignments would tend to underestimate fall-run and especially late-fall-run compositions at both trawl locations, and greatly overestimate spring-run compositions (both locations) and winter-run compositions (Chipps Island). We therefore strongly support ongoing efforts to include tissue sampling and genetic run identification of juvenile Chinook Salmon at key monitoring locations in the Sacramento–San Joaquin River system.
Experimental and numerical study of upstream slope stability in an earth dam reservoir under rapid drawdown conditions

Published: September 2021

The rapid ‎drawdown of the dam reservoir is one of the most common situations occurring in the lifetime of a dam. For this reason, one of the main factors in the design of the upstream slope is the rapid drainage of the reservoir. In this case, the upstream slope is in a critical condition and the slope may be unstable. When the water surface in the reservoir is drawdown suddenly, the water level in the dam body does not decrease at the same time as the reservoir water level. The analysis of seepage from the earth dam body and calculation of the water loss play an important role in calculating the amount of pore water pressure, and, consequently, the stability analysis of the dam body. In addition, any seepage analysis is dependent on the hydraulic properties of the dam materials. In order to investigate the effect of hydraulic conductivity on the rapid drawdown of water level and the seepage, an experimental model was constructed of an earth dam. By accurate measurement of hydraulic parameters of the materials in saturated and unsaturated media, the flow through this model was modeled using a disk penetrometer by seep/w software. The results were then compared with the observed data.
Use of morphological and anatomical characters to delimit varieties of Paliurus spina-christi Mill. (Rhamnaceae)
Authors: Shahbaz Saleem E. , Shareef Nazar M.
Published: September 2021

Introduction: Paliurus spina-christi Mill is a species with two varieties namely Paliurus spina-christi L. var. spina-christi and Paliurus spina-christivar. macrocarpa Beck native to mountains of Kurdistan, rarely growing in the upper plains of northern Iraq. Materials and Methods: A total of 15 plants from different parts of Kurdistan region were sampled. 30measurements for each characters of Leaf, Inflorescence, Flowers, Fruit, seeds, and leaf anatomical characters were measured for comparison between the two varieties. Results and Discussion: Fruit diameter of var. macrocarpa is significantly larger than fruit diameter of var. spina-christi. Most mean flower parts especially the ovary, in addition to seed size is larger in var. macrocarpa. Upper epidermal layer is always thicker than the lower epidermal layer for the same blade. The isobilateral mesophyll includes 2 layers of long palisade cells adaxially and 2-3 layers of short cells abaxially. Many vascular bundles are seen equally spaced in the mesophyll tissue.With the exception of the presence of simple hairs on the petiole adaxial side of the var. spina-cristi and the absence of these hairs from the same site of var. macrocarpa, all other anatomical features are considered to be of no taxonomic application. Stomatal density of the adaxial leaf side is up to 19 stomata per mm² in var. spina-christi while it is up to 38 stomata per mm² in var. macrocarpa. Conclusions: Both fruit diameter and the stomatal density of the adaxial leaf side constitute diagnostic characters for separating between the two varieties of Paliurus spina-christi Mill

Authors: Shakeri Mousa , Arjmand Atefeh
Published: September 2021

Introduction: One of the approaches to improve life quality in a residential complex is by modifying them properly to an educationalpublic space. An educational public space is consisted of three factors: individual, community and physical space, the importantfactor in these environments are, the proper individual and general education and respecting the natural or artificial surroundings. Basedon the probabilistic approach, an environment can have a direct impact on an individual. An environment can teach us cultural,moral and social values. The purpose of this study is to identify the criteria for designing educating public spaces in a residentialcomplex to improve the environmental quality. Therefore, the qualitative data was collected with the help of library documentsin two categories: Residential Satisfaction Factors and Educational Public Spaces Criteria. Then, both groups were adapted based oncontent validity and a questionnaire was used to collect quantitative data. The questionnaires were distributed among the architectureprofessors, according to the Delphi method. SPSS 18 software was used to analyze the quantitative data to prioritize and correlate thecriteria and micro criteria for designing educational public spaces in the residential complex. The results indicate that among all of thecriteria for an educational public space, safety is more important than other criteria, in a residential complex, the top five criteria areas follows: health and safety, aesthetics, social -cultural interactions, and national-local identity. Therefore, it can be concluded that byapplying the micro criteria of the aforementioned criteria in the communal spaces of residential complexes, the quality of residentialenvironment can be improved.

Published: September 2021

The separation of color points is one of the important issues in computational geometry, which is used in various parts of science; it can be used in facility locating, image processing and clustering. Among these, one of the most widely used computational geometry in the real-world is the problem of covering and separating points with rectangles. In this paper, we intend to consider the problemof separating the two-color points sets, using three rectangles. In fact, our goal is to separate desired blue points from undesired red points by three rectangles, in such a way that these three rectangles contain the most desire points. For this purpose, we provide a metaheuristic algorithm based on the simulated annealing method that could separates blue points from input points, , in time order O (n) with the help of three rectangles. The algorithm is executed with C# and also it has been compared and evaluated with the optimum algorithm results. The results show that our recommended algorithm responses is so close to optimal responses, and also in some cases we obtains the exact optimal response.

Published: September 2021

In the near future, preventing collisions with fixed or moving, alive, and inanimate obstacles will appear to be a severe challenge due to the increased use of Unmanned Ground Vehicles (UGVs). Light Detection and Ranging (LIDAR) sensors and cameras are usually used in UGV to detect obstacles. The definite tracing and classification of moving obstacles is a significant dimension in developed driver assistance systems. It is believed that the perceived model of the situation can be improved by incorporating the obstacle classification. The present study indicated a multi-hypotheses monitoring and classifying approach, which allows solving ambiguities rising with the last methods of associating and classifying targets and tracks in a highly volatile vehicular situation. This method was tested through real data from various driving scenarios and focusing on two obstacles of interest vehicle, pedestrian.

Published: September 2021

We characterize disjoint hypercyclic and supercyclic tuples of unilateral Rolewicz-type operators on $c_0(\N)$ and $\ell^p(\N)$, $p \in [1, \infty)$, which are a generalization of the unilateral backward shift operator. We show that disjoint hypercyclicity and disjoint supercyclicity are equivalent among a subfamily of these operators and disjoint hypercyclic unilateral Rolewicz-type operators always satisfy the Disjoint Hypercyclicity Criterion. We also characterize simultaneous hypercyclic unilateral Rolewicz-type operators on $c_0(\N)$ and $\ell^p(\N)$, $p \in [1, \infty)$.

ABSTRACT Objective: To compare indicators of tobacco use, secondhand smoke, cessation and exposure to pro- and anti-tobacco media in 2013 and 2019, and to describe these indicators according to sociodemographic variables in 2019. Methods: Cross-sectional study with data from the National Health Survey. The indicators of use, secondhand smoke, cessation and exposure to tobacco-related media were evaluated. Prevalence and confidence intervals (95%CI) were estimated for the total population in 2013 and 2019 and according to sociodemographic variables for 2019. Poisson regression with robust variance was used to assess differences in prevalence. Results: There was an improvement in most of the indicators studied: an increase in ex-smokers, a reduction in secondhand smoke and attempts to quit smoking. All pro- and anti-tobacco media exposure indicators declined. When considering the prevalence according to sociodemographic characteristics in 2019, 43.8% (95%CI 41.6–46.0) of men tried to quit smoking, and 50.8% (95%CI 48.5–53.2) of women. Secondhand smoke at home was higher among women (10.2%; 95%CI 9.7–10.8). Among those who thought about quitting smoking because of warnings, the proportion was higher among women (48.0%; 95%CI 45.3–50.6). Tobacco use was higher among men (43.8%; 95%CI 41.6–46.0), in the population aged 40 to 59 years (14.9%; 95%CI 14.2–15.6), with a lower level of education (17.6%; 95%CI 16.8–18.4). Conclusion: The study showed improvement in tobacco-related indicators between the years studied. It is noteworthy that this advance was smaller in relation to the other periods previously analyzed, and therefore, greater investments in public policies to combat and control smoking in Brazil are necessary.

ABSTRACT: Objective: to estimate the prevalence and factors associated with angina pectoris in the Brazilian adult population and per federated units. Methods: Cross-sectional descriptive study that analyzed data from the National Survey of Health 2019 and assessed the prevalence of angina in the Brazilian population. Angina was defined as chest pain or discomfort when climbing hills or stairs, or when walking fast on flat terrain (angina I) or when walking at normal speed on flat terrain (angina II). Prevalence, crude and adjusted prevalence ratios were calculated, with a 95% confidence interval, according to sociodemographic characteristics (sex, age group, self-reported race/skin color and region of residence) and federative units. Results: The prevalence of mild angina (grade I) was 8.1% and of moderate/severe angina (grade II) was 4.5%, being both more prevalent in women (9.8 and 5.5%, respectively). The prevalence increased progressively with age and was inversely proportional to years of formal study. Grade I angina was higher in individuals self-reportedly black and residents of Sergipe (10,4%). Angina II was more prevalent in people self-reportedly brown and living in Amazonas (6.3%). Conclusion: Angina affects more than 10% of the Brazilian population aged 18 years old and more, with higher prevalence in states in the North and Northeast. This is a problem that affects the most vulnerable populations unequally, which places coronary heart disease as a public health problem and points to the need to think about public policies aimed at these strata of the population.
Study of the structure and properties of a high-entropy ceramic composite material
Authors: Rusinov Peter O , M. Blednova Zhesfina
Published: September 2021

The article describes the technology development of layered surface compositions, including a high-entropy layer of a material with high-temperature memory effect of TiNiZrHfCoCu and a high-temperature ceramic layer based on zirconium dioxide ZrO2 stabilized by Y2O3. The authors also studied the structure, functional and mechanical properties of the abovementioned compositions. The proposed technology was implemented on a patented multifunctional technological complex for the formation of composite layered materials on the surface of steel products in a single technological cycle. On the basis of complex X-ray diffraction and electron microscopic studies, the structural parameters of the constituent layers of the surface composition were determined with subsequent thermal and thermomechanical treatment. The tests for ‘friction-wear’ and mechanical multi-cycle fatigue of the constituent layers of the surface composition showed a decrease in wear intensity and an increase in cyclic durability compared to the steel base. The comparison of wear intensity and cyclic durability of the surface-modified layers of the layered composition TiNiZrHfCoCu-ZrO2(Y2O3) with the composite materials obtained and studied by the authors earlier allowed the recommendation of the surface composition ‘high-entropy alloy TiNiZrHfCoCu-high-temperature ceramics’ for products of various purposes.
Liquidity Provision and Co-insurance in Bank Syndicates
Authors: Kiernan Kevin F. , Yankov Vladimir , Zikes Filip
Published: September 2021

We study the capacity of the banking system to provide liquidity to the corporate sector in times of stress and how changes in this capacity affect corporate liquidity management. We show that the contractual arrangements among banks in loan syndicates co-insure liquidity risks of credit line drawdowns and generate a network of interbank exposures. We develop a simple model and simulate the liquidity and insurance capacity of the banking network. We find that the liquidity capacity of large banks has significantly increased following the introduction of liquidity regulation, and that the liquidity co-insurance function in loan syndicates is economically important. We also find that borrowers with higher reliance on credit lines in their liquidity management have become more likely to obtain credit lines from syndicates with higher liquidity. The assortative matching on liquidity characteristics has strengthened the role of banks as liquidity providers to the corporate sector.
Пастиш
Authors: Дайер Ричард
Published: September 2021

В книге представлено первое полное исследование широко используемого, но малоизученного термина «пастиш» и его употребления. Ричард Дайер утверждает, что, хотя этот термин применим к работам, содержащим коллаж, он также может использоваться для описания произведений, сознательно имитирующих предшествующие произведения. На примерах классических литературных пастишей Пруста и текстов в тексте (пьеса в пьесе в «Гамлете», шоу внутри шоу в мюзикле «Безумства») автор рассматривает использование термина «пастиш» для описания имитаций, рассчитанных на то, чтобы их понимали и распознавали именно как имитации. Далее автор анализирует отношения пастиша с жанром, критикой и эмоциями и подробно разбирает широкий спектр примеров — «Мадам Бовари», «Щелкунчик», «Афроамериканская симфония», спагетти-вестерны («Однажды на Диком Западе»), неонуары и фильм «Вдали от рая». Дайер ратует за то, чтобы признать ценность пастиша как практики, которая идет вразрез с некоторыми общими местами критической дискуссии, показывая, что произведение может критически относиться к чему-то, не превращаясь в пародию, и способно признавать историю своего эмоционального воздействия, продолжая при этом затрагивать наши чувства. Книга адресована искусствоведам, культурологам, киноведам, философам и всем интересующимся различными видами искусства.

This protocol details how to create humanized mouse models from NSG mice. Four different variants of humanized mice can be generated based on whether or not the native thymus is retained or if a human thymus piece is transplanted. Which type of humanized mouse is desired depends on the goals for the experiment. See our protocols on NSG mouse thymectomy, human CD34+ cell isolation, and human fetal thymus preparation for more details on some of the steps in this protocol (“Thymectomy procedure to remove native thymus of NSG mice”, “Human CD34+ cell isolation from fetal liver, and fetal thymus preparation”, “CD34+ isolation from human bone marrow”).

Published: September 2021

This protocol details our approach to removing the native thymus from an NSG mouse. The NSG mouse thymus is atrophied, but through experiments in our lab, we have found that these thymi are still functional and capable of producing CD3+ cells. Removal of these native thymi prevents the production of CD3+ cells in NSG mice if a replacement thymus is not implanted. Due to their atrophic state, the native thymi are difficult to visualize during surgery and much practice is required to reduce mortality during the operation.

Responder al desprecio. Nietzsche y la genealogía de la literatura de temática homosexual en Colombia
Authors: Hincapié-García Alexánder
Published: September 2021

La literatura de temática homosexual en Colombia puede entenderse como un esfuerzo por responder al desprecio habitual con el que son representados los homosexuales. El desprecio es un lenguaje mímico de afectos, con capacidad de vincular distintas fuerzas sociales dirigidas contra determinadas formas de vida. La perspectiva teórico-metodológica adoptada se aproxima a la genealogía propuesta por Nietzsche. Por ello, no se entiende la búsqueda de origen alguno, sino el trabajo de producir interpretaciones que interrumpan la cadena de signos y significados socialmente aceptados.
Renewable energy in sustainable supply chain: A review
Authors: Marques Eduardo do Carmo , Guimarães Vanessa , De Azevedo-Ferreira Maxwel , Mancebo Boloy Ronney
Published: September 2021

In the search of sustainable process and products, ecofriendly policies have been developed over the years, aiming at reducing the environmental impacts as a step toward sustainability. Among the environmental impacts, alternatives to mitigate the greenhouse gas emissions - GHG stand out due to the concerns with climate change. Then, the development and use of renewable resources become relevant. Considering that supply chains are intense in energy consumption and GHG emissions (since involves processes related to supply, production, transport, consumption), it becomes relevant to investigate if the management of sustainable supply chain are considering the renewable energies in their processes. Therefore, this paper aims at mapping the role of renewable energies in the context of sustainable supply chain, analyzing the literature published at Web of Science database - WoS about the subject. The main researchers, organizations, collaboration networks were presented, and the 21 most cited studies were mapped in this paper. The research was carried out with the papers published at WoS until 2019, using VantagePoint software to handle information. The findings show that the research about renewable energy in the context of sustainable supply chain has been growing, especially since 2010. Moreover, biomass, biofuels and photovoltaic energy were the most recurrent sources of renewable energy studied by most cited papers. However, the theme presented itself as new and that there are still potential to be explored.
Assessment of noise and ozone levels in a small industrial urban area
Authors: Campestrini Furst Leonardo , Feliciano Manuel , Gonçalves Artur , Romero Felipe
Published: September 2021

Monitoring environmental parameters in urban centers has become a critical step for health risk assessment. In this study, conducted in the industrial park of Mirandela (Portugal), an environmental monitoring system consisting of a meteorological station, a class 1 smart sound sensor and three reference optical gas analyzers were deployed to measure noise levels, tropospheric ozone concentrations, carbon monoxide, and nitrogen oxides, during winter and spring of 2019. The interdependence among all variables was evaluated, and legal compliance was assessed according to the European Union (EU) target values for ozone. Higher concentrations of nitrogen oxides and carbon monoxide were observed during rush hours, while ozone concentrations increased as a consequence of the emissions of primary pollutants after sunrise reaching their maximum values at about 13:00 to 14:00h. Regarding the Accumulated Ozone Exposure (AOT), both target values set by the EU for AOT40 vegetation and forest have been exceeded. For AOT60, the observed values were below target; however, the threshold for NET60 was exceeded even before the end of 2019. Noise levels were higher during rush hours, because of higher traffic intensity; however, noise level indicators (Lden, Ln) remained within the legal limits. It was possible to realize that urban traffic is the most relevant source of noise and local air pollution. These results can be used to define strategies that may improve the environmental performance of the studied industrial park.

Basra böceğinin (Marchalina hellenica Genn.) konuk olduğu ve olmadığı kızılçamların (Pinus brutia Ten.) gövde kabuğu, dal kabuğu, dal odunu ve ibrelerinin fenolik bileşenleri HPLC-DAD sistemi ile belirlenmiştir. Gövde ve dal kabukları ile dal odununda ana bileşenin catechin hidrat, ibrede ise 3,4-dihydroxybenzoic acid olduğu tespit edilmiştir. Mann Whitney U Testi sonuçlarına göre basra böceğinin konuk olduğu ve olmadığı kızılçamlarda istatistiksel olarak anlamlı bir fark bulunmamıştır. Basra böceğinin yayılış alanı, ekolojik ve sosyoekonomik etkileri göz önünde bulundurularak, böceğin konukçunun ekstraktif içeriği ile ilişkisine yönelik daha detaylı çalışmalar yapılmalıdır.

Tahmin edilen kritik güç (KG) düzeyi, tercih edilen matematiksel model ve farklı tükenme zaman aralıklarına bağlı olarak %5-20 oranında farklılaşır. Bu oranlarda farklılaşan tahminler, KG ile ilişkili bir takım çelişkili sonuçlar yaratır. Bu çalışmanın amacı üç farklı tükenme aralığı (kısa: 2-10 dakika; orta: 2-15 dakika; uzun: 2-20 dakika) kullanılarak, her bir aralık için beş farklı matematiksel model (doğrusal toplam iş (KG1), doğrusal 1/zaman (KG2), doğrusal olmayan 2-parametreli (KG3), doğrusal olmayan 3-parametreli (KG4), ve üstel (KG5)), yoluyla elde edilen KG tahminlerinden hangisi ya da hangilerinin maksimal laktat dengesi (MLD), ventilasyon eşiği (VE), solunumsal kompanzasyon noktası (SKN) ve/veya kritik eşikle (KE) ilişkili olduğunu değerlendirmektir. Çalışmaya 10 iyi antrene erkek bisiklet sporcusu gönüllü olarak katılmıştır. Sporcuların VE ve SKN düzeyleri kademeli rampa testleriyle belirlenmiştir. Maksimal oksijen kullanımı, zirve güç çıktısı, MLD, KE ve KG’yi hesaplamak için farklı günlerde sabit iş oranlarında testler uygulanmıştır. Elde edilen veriler geçerlilik analizleri ile sınanmıştır. Kullanılan matematiksel model ve tükenme aralıkları değiştikçe elde edilen KG düzeyleri %20’ye kadar farklılaşmıştır. KG4 dışındaki diğer KG düzeyleri MLD ve VE’ye karşılık gelen iş oranlarından daha yüksektir (p<0,05). Kısa tükenme aralıklarıyla bulunan KG5 değeri, KE ve SKN iş oranlarına karşılık gelmiştir (p>0,05; tahmini standart hata ~%4 ve r>0,95). Tercih edilen tükenme aralığı fark etmeksizin diğer matematiksel modellerden elde edilen KG’ler herhangi bir anaerobik eşik indeksini tahmin etmede yetersizdir (p<0,05). Sonuç olarak, yalnızca kısa tükenme aralığıyla belirlenen KG5 düzeyinin, KE ve SKN iş oranlarını tahmin etmede kullanılabileceği gösterilmiştir. Diğer eşik indekslerinin KG yoluyla tahmin edilmesi uygun değildir.

Authors: KAYA Doğan
Published: September 2021

The development of effective multi-functional Pt-based nanoparticles (NPs) with enhanced activity, stability, and reduced cost for advanced applications still remains a challenge. In this study, Pt(acac)2 and Cu(OAc)2 metal precursors were reduced to form Pt-Cu NPs at 140 °C in ethylene glycol and sodium borohydride that is a secondary reducing agent in the modified polyol method. The x-ray diffraction (XRD) and Rietveld refinement analyses confirmed the face-centered cubic PtCu3 structure with the space groups of Fm3 ̅m and a lattice constant of a=b=c=3.6829 Å. The average crystal size was found to be 2.76 nm by Scherrer's formula. Scanning electron microscopy (SEM) images confirm the formation of monodisperse PtCu3 NPs with an average size of 8.04 nm within a narrow range of 5-13 nm. While energy-dispersive x-ray spectroscopy (EDS) analysis confirmed that the composition is formed of 26% Pt and 74% Cu atoms and XRD and EDS analyses were confirmed impurity, by-products, and oxidation free NPs formation.

Authors: TÜRKOĞLU Şifa
Published: September 2021

In this study, the cytotoxic and genotoxic effects of Reactive Blue 19 and Reactive Black 5 were investigated using the Allium test and comet assay. These chemicals are fabric dyes used in textile industries in various parts of Turkey. Bulbs with roots of Allium cepa L. were treated with different concentrations (25, 50 and 100 ppm) of these textile dyes for 24 h. and 48 h. The root tips were processed for cytological studies by the aseto-orcein squash procedure. Distilled water and methyl methane sulfonate (MMS, 10 ppm) were used as an negative and positive control, respectively. Exposure of Reactive Blue 19 and Reactive Black 5 significantly decreased mitotic index values. Additionally, all treatments changed the frequency of mitotic phases when compared with the control groups. These dyes increased chromosome aberrations in test material. Among these abnormalities were anaphase bridges, c-mitosis, laggards, micronuclei and stickiness. A significant increase in DNA damage was also observed at all concentrations of both Reactive Blue 19 and Reactive Black 5 examined by comet assay.

Authors: ŞAHİN Deniz
Published: September 2021

Heterotrophic marine microalga Schizochytrium sp. is one of the most studied microorganisms for docosahexaenoic acid (DHA) production. Severeal strategies were reported to enhance DHA production, including co-culturing algal cells with different microorganisms. In this study, Schizochytrium sp. and Escherichia coli were co-cultured to examine the effect of bacterial cells on the algal growth and DHA production. The cells were incubated for 168 h and recovered to analyze biomass production, lipid content and DHA yield in the mixed culture medium. Cultivation of algal and bacterial species together decreased the biomass production (g/L), total lipid concentration (ml/L), DHA yield (g/L) and DHA percentage in lipid content about 4.1, 1.7, 3.8 and 2.2 folds, respectively, compared to algal monoculture. The only increasing amount was obtained with DHA yield per biomass (mg/gCDW) which was about 1.1 fold higher in the mixed culture. The results showed that presence of Escherichia coli cells in the medium affected the growth of Schizochytrium sp. cells and DHA production negatively. It was estimated that the interaction between algal and bacterial cells were competition instead of mutualistic interaction in which bacterial cells outcompeted the algal cells and limited the cell density increase of algal cells in the mixed culture.

Published: September 2021

The Zinc Sulfide (ZnS) thin films were produced at 60 ºC on glass slides with the chemical bath deposition (CBD) method. The ZnS films were annealed for 1 hour at different temperatures in the air atmosphere. UV-visible spectrophotometer, X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), four-point probe technique and Hall-effect measurement techniques were used to examine the thermal annealing's effect on the films' optical, structural, and electrical properties. It was observed that with increased annealing temperature, the film thickness increased and thus the energy band gap decreased. It was seen that the particle size of the ZnS films grew depending on the annealing temperature, and the crystal structure turned into an amorphous structure. Finally, it was determined that with the impact of annealing the carrier type did not change, and the conductivity of the ZnS thin films increased.

For the determination of quercetin, an accurate, economical, time-saving and a new environmentally friendly method has been developed with a simple spectrophotometer device available in every laboratory. As a solid-phase sorbent, a new polymer nanocomposite has been synthesized and characterized by Fouirer Transform Infrared Spectroscopy (FT-IR) and Scanned Electron Microscopy (SEM). Experimental solid phase extraction variables have been investigated and optimized step by step, such as pH, adsorption time and desorption conditions, etc. According to optimization results, desorption of quercetin molecules was carried out by 2-propanol solvent and absorbance of eluent solutions were measured as systematic at 255 nm and at 370 nm. However, the best results were obtained at 370 nm wavelength. Therefore, all measurements were made at 370 nm. (LOD) means that the detection limit and (LOQ), the quantitation limit values for quercetin were calculated as 5.97 ng mL-1and 17.91 ng mL-1, respectively. Standard addition and recovery experiments were performed as an indicator of the accuracy of the method. The method developed was effectively conducted to model solutions.
