Authors: Md. Ashikur Rahman  , M. H. Sazzad  , R. S. Rupom
Published: June 2021

Water is an important resource of the earth’s surface and it is integral for all on this planet. The availability or the scarcity of water depends on the watershed characterizes that consider the basic, linear, and shape parameters of any waterbody. The objective of the study was to delineate 14 morphometric parameters in the Barind region (Dinajpur district, Bangladesh) for sustainable hydrological modeling. An ASTER-DEM of 30-meter resolution data, geographical information system (GIS), and Remote sensing technique were used for extracting drainage components of interest region. The whole study region was covered by the flow of the Purnovoba river, Jamuna river, Atrai river (part-1 and part-2). Research results found that the Purnovoba river had a high bifurcation ratio (0.9982) that defined hydrologically more disturbed than the other three watershed areas and it had a high stream frequency (0.8332) that denoted rocky having low infiltration capacity. Jamuna river had a low drainage density (0.7322) that defined more vegetation having higher permeability. Besides, the Jamuna river had the lowest no. of stream order that was insignificant in the steady runoff process and less prone to cause a flash flood. The research predicted that the availability of groundwater might decrease to Jamuna river in the future as it had the lowest basin area (217.42 sqr. km ) and perimeter (114.90 km) and the basin surface slope would become gentle to Atrai river part-1 for the lowest length of overland flow (0.6072). Purnovoba river experienced the lowest form factor  (0.2351) which indicated the most possibility for erosion. The elongated ratio of all basins was greater than 0.5 which considered all the shapes were more elongated. These findings will help for further modeling of an integrated watershed for sustainable hydrological models in the Barind region.

Published: June 2021

Sundarbans, the largest mangrove forest located over the GBM basin, has impacted lives of millions over the years. Standing against various natural disasters, rivers of Sundarbans have undergone major issues such as erosion-accretion of both the banks. The paper deals with a combination of remote sensing and Digital Shoreline Analysis System (DSAS), studying temporal behaviour of bank-lines along the main rivers of Sundarbans for the last three decades. The course of main rivers spanning from southwest Baleswar to west Bengal Bidyadhari within coverage of 10,000 sq. km. has been analyzed in this study. DSAS, the extension tool of ArcGIS, was used for monitoring the rate-of-change from multiple historic bank-line positions extracted from satellite images. Comparison of historic bank-lines between different rivers of Sundarbans was done based on Net Bank-line Movement (NBM) with an interval of five years. Finally, the results were presented graphically to get a better understanding of the bank-line behaviour. The study revealed that the western region of mangrove prevails eroding behaviour than the eastern region. Increased rates of riverward movement due to accretion was found from 2008-2013. These results are important for future monitoring and proper management within the coastal communities surrounding the mangrove forest.

Published: June 2021

This study developed an ozone generator of a double co-axial cylindrical dielectric barrier discharge system with air, argon, and oxygen as the working gases. The discharge was produced by using a high voltage power supply of 0 - 18 kV and a line frequency of 50 Hz. The flow rate of air, argon, and oxygen was varied from 1 to 6 L/min. A comparison of O3 generation in air, argon, and oxygen using brass as a central electrode was conducted and it was found that O3 concentration was higher in the case of oxygen than in the air and in argon gases environment for given fixed discharge time, applied voltage, and diameter of the brass electrode. This study revealed that the concentration of ozone increased along with the increase in the applied voltage for constant discharge time and gas flow rate. The O3 concentration also increased with the increase in the discharge time at fixed applied voltage and gas flow rate; however, the concentration decreased with the increase in the gas flow rate at fixed discharge time, applied voltage, and diameter of the electrode. A small reactor with a large inner electrode generated a high concentration of O3. Yet, a reactor with a small diameter, there seemed to have an optimum inner electrode diameter. The glass tube reactor of the internal diameter of 18 mm and the brass electrode of diameter 8 mm were utilized in this study. The ozone concentration was higher for oxygen as feed gas than both in the air and in argon and the O3 concentration was also higher in the air than in argon at fixed discharge time, applied voltage, and diameter of ozone generator.
HIGHLIGHTS

Ozone concentration increases with increasing applied voltage and discharge  time but concentration decreases with increasing gas flow rates
Low cost ozone can be produced in DBD reactor at atmospheric pressure
Oxygen can be used as feed gas to generate high concentration of ozone than other gases inside DBD generator
Optimization of central electrode diameter and gap space inside DBD reactor can help to increase ozone concentration, yield, and efficiency
Proper choice of central high voltage electrode also can play the important role for the generation of ozone in DBD chamber

Authors: Karaca Bilal Bahadır
Published: June 2021

Orta Avrupa, jeopolitik önemi nedeni ile yıllar boyunca büyük güçler arasında süren güç mücadelesinin bir nesnesi konumunda yer almıştır. İkinci Dünya Savaşı sonrasında Sovyetler Birliği'nin kırk beş yıl etkisi altında kalan Orta Avrupa Devletleri, Demir Perde'nin çökmesi ve Sovyetler Birliği'nin dağılması ile siyasal özgürlüklerine kavuşmuştur. Bu Orta Avrupa Devletleri'nden üç tanesi, daha doğrusu 1993 yılında Çekoslovakya'nın, Çek Cumhuriyeti ve Slovakya olarak ayrılması ile dört tanesi, Vişegrad Grubu'nu oluşturarak hem çeşitli alanlarda birbirleri arasındaki iş birliğini kuvvetlendirmiş hem de yeni rotaları olan Avrupa entegrasyonunu hızlı bir şekilde hayata geçirmişlerdir. Keza Avrupa Birliği ve NATO üyesi olarak Vişegrad Grubu ülkeleri, bu süreci başarıyla geçmiş ve Avrupa-Atlantik yörüngesinin bir parçası haline gelmişlerdi. Sovyetler Birliği'nin dağılmasından sonra çeşitli siyasal, sosyal ve ekonomik krizlerle uğraşan Rusya Federasyonu ise Putin'in liderliğinde eski gücüne ve özgüvenine kavuşmuş ve geniş bir dış politika vizyonu ile tekrar önemli bir güç haline gelmiştir. Uluslararası sistemde yeniden pozisyon alan bu ülkeler arasındaki ilişki incelenmeye değer bir hal almıştır. Bu bağlamda, çalışmamızda Vişegrad Grubu ülkeleri ile Rusya Federasyonu arasındaki ilişkiler analiz edilmiştir. Temel araştırma problemi olarak Vişegrad Grubu ülkelerinin Rusya Federasyonu ile olan ilişkilerinde ortak bir politik pozisyon alıp almadıkları ele alınmış ve bu ülkelerin politik pozisyonları yansıtılmaya çalışılmıştır. Çalışmamızda neoklasik realizmin teorik çerçevesinde bir yaklaşım sergilenerek sadece uluslararası sistem düzeyinde bir analiz yapılmamıştır. Ayrıca ülkelerin iç dinamiklerinin uluslararası sistem ile etkileşimi karşılaştırmalı araştırma metodu kullanılarak incelenmiştir.

Published: June 2021

Zeka, yaratıcılık, liderlik, sanat, motivasyon ve akademik alanlarda yaşıtlarına göre yüksek düzeyde performans gösteren öğrencilere özel yetenekli öğrenci denilir. Öz düzenleme, kişinin davranışlarını gözleyip, ölçütleriyle karşılaştırarak belli bir yargıda bulunması, gerekli ise kendi davranışlarını ölçütlerine uyumlu hale getirmesidir. Birçok organize olmuş davranışımızın arkasında içsel süreçler önemli ölçüde rol oynamaktadır. Pandemi sürecinde birçok insan yaşadıkları aşırı kaygı nedeniyle kendi performanslarını ve motivasyonlarını kontrol etmede zorluk yaşadı ve bu da onların bilişsel sürecini zorladı. Çalışmadaki amaç pandemi nedeniyle ilk defa eğitim-öğretim sürecinde geçtiğimiz uzaktan eğitim sürecinde akademik alanda, yaratıcılıkta yaşıtlarına göre başarılı ve öğrenme için yüksek motivasyona sahip olan tanılanmış özel yetenekli lise öğrencilerinin kendi öğrenme sorumluluğunu alıp bu süreci kontrol edebilme becerilerini incelemektir. Araştırmada “Uzaktan eğitim sürecinde özel yetenekli olan lise öğrencileri kendi öğrenme sorumluluğunu alarak kendi öğrenmelerini nasıl düzenlediler?” problem cümlesine çözüm arandı. Araştırmada Kayseri’de farklı lise türlerinde okuyan 35 özel yetenekli BİLSEM öğrencisine yarı yapılandırılmış görüşme formu uygulandı. Araştırmada nitel yöntem kullanıldı. Katılımcılardan elde edilen görüşme verileri betimsel analiz yoluyla analiz edildi. Elde edilen veriler doğrultusunda uzaktan eğitim sürecinde özel yetenekli öğrencilerin büyük çoğunluğu kaygı düzeyini kontrol ederek ve motivasyon sağlayarak kendi öğrenme sorumluluğunu aldılar. Bu süreçte ben nasıl öğrenirim sorununu kendileri çözdüler, zamanı etkili kullanmada başarılı oldular, kendi öğrenmelerini düzenlediler. Araştırma şuana kadar akademik başarılarda öne çıkan özel yetenekli öğrencilerin böyle bir zor durumunda kontrolü sağlayarak öz düzenleme kapasitelerinin ortaya çıkarılması için önem taşımaktadır.
Rusya’da hükümet ve medyanın 15 Temmuz darbe girişimine yaklaşımları
Authors: Taşcı Tekin Aycan
Published: June 2021

Başlangıcı 15. yüzyılın ikinci yarısına tarihlendirilen Türk-Rus ilişkileri yüzyıllar boyunca bölgesel rekabet ve buna bağlı olarak düşmanlık çerçevesinde gelişme göstermiştir. İki taraf arasında kısa süreli de olsa ilk kapsamlı dostluk ve işbirliğine dayalı ilişkiler Sovyetler Birliği ve Türkiye Cumhuriyeti arasında yaşanmıştır. Soğuk Savaş sonrası dönemde, bilhassa 2000’li yıllardan itibaren ilişkilerde rekabetten işbirliğine geçiş yönünde ciddi adımlar atılmaya başlanmıştır. Fakat 24 Kasım 2015’te Türkiye’nin Rusya’ya ait bir savaş uçağını düşürmesi ilişkilerin seyrini değiştirmiş ve iki ülke arasında kuvvetlenmeye başlayan güven ortamını yıkmıştır. Kriz döneminde Rusya tarafının eylem ve söylemlerinde gösterdiği Türkiye aleyhtarlığı ise basın yayın organlarında yürütülen kara propaganda sayesinde Rus kamuoyunda derin izler bırakmıştır. 27 Haziran 2016’da Ankara’dan gelen taziye mektubu sonrası Türk ve Rus hükümetleri tarafından ilişkilerin hızla düzeltilmesi yönünde irade sergilenmesine rağmen Rus basınındaki Türkiye algısı temkinli ve şüpheci olarak kalmıştır. 15 Temmuz 2016 tarihinde yaşanan darbe girişimi karşısında Rus Hükümeti açıkça Türkiye’deki meşru iktidarın yanında tavır sergilerken, Rus yayın organları ve Rus uzmanların yaklaşımları farklılıklar göstermiştir.

Authors: Bastos Maria Flávia , Souza Neto Bezamat de , Diniz Daniela Martins
Published: June 2021

Resumo: No contexto da educação empreendedora, o objetivo deste artigo teórico é propor uma reflexão sobre temas centrais relacionados ao empreendedorismo, particularmente, sobre capacidades empreendedoras, autoconhecimento para o empreendedor e economia criativa por meio do Design Thinking, a partir de um processo de aprendizagem que articula teoria e experimentação prática. As discussões baseadas nos principais autores da área são acompanhadas pela proposição de atividades reflexivas para que os empreendedores iniciantes (ou os não empreendedores) pratiquem temas relevantes dentro do campo do empreendedorismo com a finalidade de provocar um processo de reflexão, de autoconhecimento e de aprendizagem prática. Nessa direção, este artigo resgata experimentos na contramão da formação empreendedora “tradicional” com a premissa básica de que a educação empreendedora deve apoiar-se na descoberta ou redescoberta do empreendedor em um processo de aprendizagem que estimule não somente a transferência de conhecimentos do “mestre” para o “ouvinte”, mas o uso de metodologias reflexivas de educação em que o “aluno” assume um papel protagonista. Em relação à sua contribuição, este estudo busca despertar o interesse dos não-empreendedores acerca do empreendedorismo como uma possiblidade de trajetória profissional e chamar atenção para o fato de que a educação empreendedora requer atividades de experimentação, reflexão e autoconhecimento. Palavras-chave: Educação Empreendedora. Capacidades Empreendedoras. Autoconhecimento. Design Thinking.

Moroccan High School EFL Teachers’ Attitudes and Anxiety on Using Microsoft Teams Platform
Authors: Sayeh Adil Youssef , Razkane Hassane
Published: June 2021

The world has witnessed major changes in delivery modes in education due to the COVID-19 pandemic. Being no exception, Morocco declared a full lockdown in March 2020, and this resulted in the use of online platforms to cope with the new situation. The platform that was adopted by the Moroccan Ministry of Education was Microsoft Teams (MT). Hence, the current paper investigated Moroccan high school EFL teachers’ use of the platform accounting for their age, gender, anxiety, and attitudes towards the platform. For this aim, a questionnaire adapted from Computer Anxiety Rating Scale (CARS) by Heinssen et al. (1987) was distributed to 171 EFL teachers working in different public high schools belonging to the academy of Casablanca/Settat. Results revealed that the participants’ attitudes towards the usability of the platform were negatively associated with their years of experience, and their general anxiety and power and control of the platform negatively affected the time they spent on the platform. The findings imply that anxiety should be taken into consideration as an integral component in further implementation of technology in education.
Patrimonio Escrito, Historia Pública e Itinerarios turísticos: una experiencia docente transversal
Authors: Adámez Castro G. , Martínez Martín L.
Published: June 2021

Las nuevas líneas y usos que propulsa la Historia Pública son un excelente acicate para que los historiadores/as, así como los docentes de esta disciplina, apuesten no solo por renovar sus investigaciones sino también por realizar cambios en las aulas que saquen la Historia a la calle y llegar así a un público no especializado, pero cada vez más demandante de conocimientos históricos. En esta línea, el binomio Historia-Turismo tiene mucho que aportar, como demuestra la presencia cada vez mayor del Turismo Histórico y que aumenten los visitantes que eligen rutas culturales e históricas. Todavía es mucho lo que se puede avanzar, máxime cuando se trata de revalorizar un patrimonio que suele pasar desapercibido, incluso para los gestores culturales: el Patrimonio Escrito. Nuestras ciudades están llenas de escritura: grafitis, carteles publicitarios, bandos informativos, avisos, anuncios por palabras, estelas, placas, etc. Nuestro propósito en este artículo es acercarnos a los itinerarios turísticos como medio para divulgar la Historia a través del Patrimonio Escrito y analizar sus múltiples posibilidades. Para ello, reflexionaremos en torno a un estudio de caso a partir de nuestra experiencia docente en la asignatura transversal Patrimonio histórico y cultura escrita: nuevos itinerarios turísticos que impartimos en la Universidad de Alcalá, que supone un ejercicio práctico que pretende aunar la Historia Pública, los itinerarios turísticos y el Patrimonio Escrito.

O contexto pandêmico tem despertado reflexões acerca das lacunas na proteção de crianças e adolescentes em nosso país. Os problemas já existiam, mas foram potencializados e escancarados com a crise humanitária que vive o Brasil. As consequências dos problemas relacionados ao sofrimento emocional, aos riscos aos quais são submetidos crianças e adolescentes diante de violações de direitos, cyberagressões e situações de violência doméstica tornam as instituições que atendem esse público, em especial, a escola, os únicos locais que representam proteção e segurança para falar de sentimentos, problemas e medos vivenciados por eles. Assim, a formação dos profissionais que ali atuam torna-se fundamental. Além do que, um alerta deve ser feito: a escola precisará estar atenta a tais demandas no retorno das atividades presenciais ou se tornará, em breve, palco de novas tragédias por representar a convivência não cuidada e a proteção não garantida a crianças e adolescentes vulneráveis.

Improving the efficiency of using tractor-transport units (tractor trains) in the central agricultural zone of the Amur Region is an economically important issue, especially relevant for small peasant farms. This is due to the fact that in such farms the area of fields occupied for the cultivation of agricultural crops is relatively small, while most of them belong to the category of slope lands. It was also found that during the periods of sowing and harvesting operations, traffic on agricultural roads is hampered by safety conditions due to regional climatic features, which include a large amount of precipitation. In this connection, the use of vehicles for the transportation of seed, fertilizers, plant protection products and other goods, and the export of crops in these conditions seems to be a rather complicated operation. It should be borne in mind that in many, the main energy means are wheeled tractors of class 1.4, and not cars of various cross-country ability, therefore, in order to increase the efficiency of the use of available mechanization means, it is necessary to use them for the transport of goods, and as part of multi-link tractor trains in particular. At the same time, when driving on on-farm field roads with a limited width, the turn of multi-link trains is difficult due to the failure of the second and subsequent aggregated trailers to comply with the safe transport corridor, since the second trailer, when turning, shifts to the center of the road and creates an emergency situation for oncoming traffic. In order to eliminate the identified shortcomings and create safe conditions for traffic, an automatic device was developed that allows you to shift the second trailer when turning from the center to the side of the passing traffic, thereby regulating the transport corridor and not creating emergency situations for oncoming traffic. The paper presents the results of experimental studies on the use of a transport unit consisting of a class 1.4 tractor and two 2PTS-4 trailers in the production modes of multi-link tractor trains.

Objective:to evaluate the correlation between the values of the magnetic resonance imaging (MRI) apparent diffusion coefﬁcient (ADC) and the count of cellularity in histological material and to establish a relationship between the cellular structure and the prognostic properties of MRI with diffusion-weighted imaging (MRIDWI) in various morphological types of lymphomas.

Materials and methods.101 patients with morphologically veriﬁed lymphoma (Hodgkin lymphoma (HL) — 52 patients, non-Hodgkin lymphomas (NHL) — 49) underwent whole body MRI-DWI before treatment and ADC measurement in the target lesion. An excisional biopsy of the lesion was performed from the same anatomical area and the count of cellularity in the histological material was determined.

Results.In HL, aggressive NHL and diffuse large B-cell lymphoma (DLBCL), ADC is statistically signiﬁcantly higher, and cellularity is lower than in indolent NHL and cells of the mantle zone of NHL. We have found an inverse correlation between the values of ADC and cellularity in aggressive NHL (ρ = -0.47, p = 0.005) and DLBCL (ρ = -0.48, p = 0.006).

Conclusion.ADC values depend on the cellular structure of the lymphomas. The correlation of ADC and cellularity values of various morphological types of lymphomas allows explaining the prognostic properties of ADC.

Objective: to identify the molecular genetic criteria of the risk of tension-type headache and migraine chronization development.

Materials and methods. The detection of the results for the determination of allelic variants was carried out by means of horizontal electrophoresis using a molecular weight marker. The determination of the genotypes of the polymorphic variants of genes was carried out using high resolution melting PCR analysis.

Results. Based on the performed molecular genetic studies, it has been established that the statistically signiﬁcant (p < 0.05) risk factors of tension-type headache chronization are: the identiﬁcation of the A-allele and AA-genotype of the DBH3 polymorphism of the dopamine-beta-hydroxylase gene DBH, as well as the identiﬁcation of the G-allele and the GG-genotype of the Intron3SNP polymorphism of the preprotachykinin gene TAC1. It has been found that the statistically signiﬁcant (p < 0.05) risk factors of migraine chronization are: the identiﬁcation of the A-allele, GA- and AA-genotypes of the G29A polymorphism of the serotonin transporter gene SLC6A4, as well as the identiﬁcation of the G-allele and the GG-genotype of the rs7793277 polymorphism of the preprotachykinin gene TAC1.

Conclusion. The detection of these polymorphisms of the dopamine and preprotachykinin genes in the blood serum increases the risk of tension headache chronization by 1.395–1.991 times; the risk of migraine chronization by 1.235–1.395 times.

Published: June 2021

Objective: to analyze literature data on the effectiveness of preoperative mechanical bowel preparation (MBP), and on the basis of our own data to perform a comparative analysis of immediate MBP results in patients operated on right-sided colon cancer.

Materials and methods. We reviewed literature data relevant to the use of MBP and performed a retrospective analysis of the immediate results of surgical interventions on right-sided colon cancer in 349 patients having undergone MBP with polyethylene glycol (PEG) compounds (n = 186) and without the use of PEG (n = 163).

Results. The incidence rates of complications in the patients of groups I and II were 6.7 % and 9.8 % (P>0.05), anastomotic leak rates were 0.6 % and 1.6 % (P>0.05), postoperative death rates — 1.2 % and 1.6 % (P>0.05), the average durations of the postoperative period were 14.9 and 12.1 days, respectively (P>0.05).

Conclusion. The use of preoperative MBP with PEG compounds does not result in enhancing the immediate results of the surgical treatment of patients with right-sided cancer.
Detection of liver diseases in patients over 60 years in therapy wards
Authors: Paltsev I. V.
Published: June 2021

Objective: comparative assessment of the detection of diseases of the hepatobiliary system in patients of different age groups undergoing treatment in therapy wards.

Materials and methods. The epicrises of patients undergoing treatment in therapy wards were analyzed. The parameters of biochemical blood test, coverage of ultrasound examination, diagnoses based on the results of examinations were assessed. Statistical data processing was performed.

Results and discussion. Cholelithiasis was more common (13.4 % and 2.6 %, p = 0.0001) in patients over 60 than in those who were under the age. The prevalence rate of non-alcoholic fatty liver disease was higher among patients under 60 years old (9.6 % and 0.3 %, p = 0.002). An increase in ALT was detected in 12.1 % of the cases, ultrasound examination was performed in about half of patients with high ALT. The high prevalence rate of heart failure may have inﬂuenced the detection of liver disease.

Conclusion. Insufﬁcient detection of liver pathology in patients over 60 is due to a rare increase in ALT activity, incomplete coverage of patients by ultrasound examination, and the presence of concomitant pathology.

Synthesis of 3-(1-((benzoyloxy)imino)ethyl)-2H-chromen-2-ones (1-5) was accomplished and it was characterized experimentally using various analytical techniques. Computational studies have been carried out for all compounds 1-5 using B3LYP method with 6-311++G(d,p) basis set. The optimized structural features viz. bond lengths, bond angles, and dihedral angles are compared with their single-crystal X-ray diffraction results of compound 1 (Crystal data for C18H13NO4 (M = 307.29 g/mol): Monoclinic, space group P21/c (no. 14), a = 11.399(5) Å, b = 5.876(5) Å, c = 21.859(5) Å, β = 91.060(5)°, V = 1463.9(14) Å3, Z = 4, T = 293(2) K, μ(MoKα) = 0.100 mm-1, Dcalc = 1.394 g/cm3, 13555 reflections measured (3.58° ≤ 2Θ ≤ 56.98°), 3669 unique (Rint = 0.0235) which were used in all calculations. The final R1 was 0.0444 (>2sigma(I)) and wR2 was 0.1506 (all data)), which are in good conformity with each other. Normal modes of vibrational frequencies of compounds 1-5 acquired from density-functional theory (DFT) method coincided with the experimental ones. The 1H and 13C chemical shifts of compounds 1-5 have been calculated by GIAO method and the results have been compared with the experimental ones. The first-order hyperpolarizability and their related properties of the novel molecules 1-5 are calculated computationally. The other parameters like natural bond orbital, zero-point vibrational energy, EHOMO, ELUMO, heat capacity and entropy have also been discussed.

The title compound lies about a crystallographic inversion centre located at the terephthalate moiety. The two peri-benzoylnaphthalene units having atrope chirality are also situated centrosymmetrically. In the two peri-benzoylnaphthalene moieties, two benzoyl groups are substituted at 1 and 8 carbons of the naphthalene ring in anti-orientation. Then two absolute configurations of peri-benzoylnaphthalene moieties are consequently assigned as complementary to each other, i.e., one unit has R,R-configuration and the other S,S-one, respectively. The two benzoyl groups in peri-benzoylnaphthalene moiety and the terephthalate phenylene ring are non-coplanarly located against the naphthalene ring. The dihedral angles of each benzene ring of two benzoyl groups and terephthalate unit with the naphthalene ring are 73.73 and 75.96, and 71.79°. In molecular packing, several kinds of weak interactions are responsible to induce three-dimensional molecular network. Especially, the synergetic effect realized through the bidentate hydrogen acceptor function in bidirectional C-H···π non-classical hydrogen bonds by the terephthalate phenylene ring moiety plausibly plays the determining role.
Reactions under increased pressure: The reactivity of functionally substituted 3-oxo-2-arylhydrazones toward active methylene reagents in Q-tube
Authors: AlMarzouq Douaa Salman
Published: June 2021

A one-pot two-component reaction of 3-oxo-2-arylhydrazones with active methylene nitriles under high pressure in a Q-tube safe reactor was reported. Comparison between conventional and Q-tube safe reactor-assisted synthesis of organic compounds was done by comparing total reaction time and percentage yield. The results show that the compound 5-cyano-6-oxo-1,4-diphenyl-1,6-dihydro-pyridazine-3-carboxylic acid ethyl ester (3) was synthesized within 2 h in a yield of 97%. In addition, the pyrazolo[3,4-c]pyridines 5b and 5c were obtained in yields of 93 and 95% within 1 h reaction time, respectively. The obtained results suggest that Q-tube safe reactor-assisted syntheses were led to higher product yields within very short reaction times.

Published: June 2021

Assembly of small building blocks such as atoms, molecules, nanoparticles, and microparticles into macroscopic structures has opened up new and exciting opportunities in the realm of nanotechnology and microtechnology. Here, we report a simple hydrothermal approach for assembling chromic hydroxide microscopic particles into three-dimensional chromic hydroxide with cylindrical morphology. The morphology and size as prepared samples are controlled by the concentration of Cr(NO3)3. Our approach provides a reliable way to successfully assemble various other types of particles into cylindrical macrostructures, realizing the shape engineering of nanoscale and microscale structures to macroscopic well-defined architectures for further applications.
