O leitor vai sendo conduzido de um olhar panorâmico sobre o carnaval, para uma focalização na divisão social dentro do evento carnavalesco do século XIX para o XX: O trunfo da pesquisa é o caráter documental e investigativo, avançando para além da contribuição dos pesquisadores anteriores e jornalistas que se debruçaram sobre a história desse rancho.
Entrance of Transverse Colon Volvulus into the Diaphragm Defect: A Case Report
Authors: Rahimi Zarei Navid , Hossein Golezar Mohammad
Published: July 2023

Background: Colonic volvulus is an uncommon yet clinically important condition. It can occur in different locations; however, transverse colon and splenic flexure are rarely involved. We hereby present a 62-year-old man with a rare condition of herniation of transverse colon and splenic flexure within the chest cavity. Case presentation: A 62-year-old man was admitted to our center, a teaching hospital in Iran, complaining about three-day abdominal pain, anorexia, constipation, and abdominal distention. He was intellectually disabled and had a previous history of chronic constipation. The imaging studies showed the bowel loops herniated into the thoracic cavity. A laparotomy procedure was performed. The twisted transverse colon and splenic flexure were present in the left hemithorax. Total colectomy and ileostomy were performed and the diaphragmatic defect was repaired. Conclusion: This work aimed to raise attention to the rare condition of concurrent diaphragmatic hernia and colonic volvulus. The diaphragmatic hernia can be a life-threatening condition per se. If it is accompanied by intestinal volvulus in rare cases, it creates a pressing condition. More studies are required to explain the etiology of this potentially fatal condition.
The Magseed Marker in Impalpable Breast Cancer: A Single Centre Review of Efficacy and Safety
Authors: Armstrong L , Scally Norah , Lockhart J , Mathers H
Published: July 2023

Aim: A cohort observational study was conducted, aiming to review the overall efficacy and safety of the Magseed localisation technique in non-palpable breast cancer, in comparison to wire guided excisions (WGE). Methods: Data was collected in a single centre, on all patients undergoing image guided breast conserving surgery between April 2018 and August 2019, with a planned accumulation of 100 patients undergoing Magseed localisation. During the same period, data was also collected for 100 consecutive patients undergoing WGE. Primary end points observed included excision volumes and re-excision rates. Results: Re-excision rates due to positive margins were significantly higher in the WGE group (WGE 26% vs. Magseed 8%, p<0.05). Specimen sizes by weight were also larger for WGE group (WGE 50.4g vs. Magseed 31.2g p=<0.05). 41% of WGE cases were delayed (average 62mins) when compared to 0% of Magseed cases. Conclusions: The previously recognised gold standard method of WGE has documented limitations. Our study illustrates the Magseed marker as an effective alternative method of lesion localisation, which reduces re-excision rates, improves theatre scheduling, and reduces volume of excision tissue, improving overall cosmetic outcome.

Authors: Arrotegui Inaki
Published: July 2023

Summary: Due to its pharmacodynamic capabilities and its properties at the cell membrane level, vancomycin is considered one of the glycopeptides for clinical use as first-line treatment against most Gram-positive germs. Objective: To analyze the efficacy of topical vancomycin in the prevention of infections at the surgical wound level in spinal surgery. Material and methods: A non-randomized, observational and comparative cohort study of 60 patients with instrumented lumbar spine surgery was carried out in the period between June 2021 and june 2022. In 30 cases with placement of 1 g of topical vancomycin group 1, and 30 did not Group 2, in a nonrandomized manner. Patients were followed up during the first 90 postoperative days. Results: The relationship between vancomycin-infection was not statistically significant, 3 cases of wound infection were identified in the group without vancomycin, it was found that the factor of age over 50 years and Diabetic or immunosuppressed and obesity were predisposing causes respectively, although without p ≤ 0.05, another finding was the RR 2.0208 in an instrumented lumbar level but without significant difference; the main characteristics in the 3 patients with wound infection were only present in the group without vancomycin, identifying. Conclusions: There is no statistical significance in our study that topical vancomycin plays a fundamental role in the prevention of infections at the surgical wound level in spinal surgery. However, it is important to note that all the infected patients in this study belonged to group 2 (without the use of vancomycin).

Published: July 2023

Background: Non-puerperal uterine inversion (NPUI) is a rare gynecological affection whose scarcity makes its diagnosis challenging. Uterine inversion may be -acute- most seen in obstetrics as a complication of the third stage of labor or- chronic- due to uterine benign or malign tumors. Case report: We proffer two cases of non-puerperal uterine inversion presenting to our emergency department complaining of a protruded mass through the vagina outside the introitus. The first one outlays the second reported case - to our knowledge- in a patient without sexual experience of a uterine inversion due to a leiomyosarcoma, presenting in an acute state, leading to hemorrhagic shock. The second case occurs after recurring uterine inversions due to a known submucosal myoma. Both diagnoses relied on physical examination where not being able to palpate the uterus was the cornerstone of clinical suspicion. Using ultrasound as imaging investigation was pivotal to confirming the diagnosis and an etiology, uterine tumors. For different reasons, both patients underwent transvaginal hysterectomy. Conclusion: NPUI is a complicated clinical condition where the diagnosis is often exacting. If accurately and timely managed, it has an excellent prognosis. It’s very important to define the tumor’s histopathological profile before choosing one of the underlining known surgical and non-surgical procedures. However, taking into consideration fertility and the patient’s desire should be mandatory before deciding on any course of action.

The Evolution of Vocational Education Titles in China: A Historical Investigation
Authors:   Yixin Publisher, Gong Zili , Yang Yongbing
Published: July 2023

Vocational education, as an exact academic term, originated from “Tianpin Putong Jiaoxiwen” written by Yao Wendong, the general manager of Shanxi Agriculture and Forestry School in 1904. However, the practice of vocational education as a type of education runs through the development of Chinese society, and its emergence and development have experienced a relatively long evolution process. In China, vocational education has experienced the development of traditional apprenticeship, industrial education, vocational education, technical education, and vocational and technical education. With the promulgation and implementation of the Chinese Vocational Education Law in 1996, and vocational education practice and theoretical exploration for more than 40 years since the reform and opening up, it was not until the 2014 national policy document that vocational education was finally adopted as a parallel education type of Chinese general education. Only when there is a clearer understanding of the characteristics and essential attributes of vocational education as a type of education and a consensus is reached, the dispute over the title of vocational education will gradually subside in the academic circle.

Features and state of development of freight and passenger transportation by rail in the countries of the Visegrad Group
Authors:   Akademia Nauk Stosowanych Gospodarki Krajowej, Białobłocka Magdalena
Published: July 2023

The article analyzes the features and state of development of freight and passenger transportation by rail in the countries of the Visegrad Group. It is based on the confirmation of the fact that the countries of the region traditionally have a modal split in freight and passenger traffic between rail and road transport. The author recorded that the share of rail transport in the transportation of goods and passengers in the countries of the Visegrad Group is declining or remains stable, and the share of road transport is growing. Thus, the peculiarity of railway transport in the region is that it is gradually losing its popularity and share at the background of road transport, and this tendency has been observed for several decades, i.e. from the collapse of the regimes of “real socialism” up to today. In this context, it was argued that even despite variable attempts, the railway sector of the Visegrad Group countries is characterized by a severe recession primarily as a result of the collapse of the planned economy, resulting in a sharp decline in rail traffic.
Crystalline lens: redox changes in response to the action of non-ionizing electromagnetic radiation
Authors: Gadzhiev A.M. , Ibrahimova J.M.
Published: July 2023

Electromagnetic radiation (EMR) in the microwave range, even at non-thermal intensity, causes significant biochemical and physiological changes in living organisms, which are supposed to be associated with its possible oxidative effect. This work is devoted to the study of the mechanism of realization of the EMR effect in the eye lens at the level of redox state elements, based on the fact that this organ is the most suitable model: it functions semi-autonomously and has a well-organized system of antioxidant protection. The transparency of the lens is maintained by preserving the redox balance, in which the homeostasis of thiol compounds of protein and non-protein nature plays an important role. Our experiments were performed on rats using 460 MHz EMR for exposure at non-thermal intensities (power flux density between 10 and 30 µW/cm2). It has been shown that chronic exposure to EMR for up to two weeks caused changes in the redox state of the lens, which manifested in changes in the level of lipid peroxidation processes and the content of thiols of various natures. The substructures of the lens (cortical and nuclear regions) reacted to EMR exposure in different ways. Depending on the EMR intensity, pro- and antioxidant characters were revealed in their reactions. The dynamics of the oxidative reaction of lens substructures were also different under high- and low-intensity exposure. The character of the kinetics of changes in the products of oxidative reactions (malondialdehyde and lipid hydroperoxides) and reducing agents (non-protein and protein SH groups) in the lens of the irradiated organism suggested the role of the enzymatic thiolation-dethiolation system to preserve the redox balance in the substructures of the lens. In addition, the results on changes (kinetics) in the content of various protein SH-groups, i.e., hidden inside the protein molecule and exposed on its surface, during EMR exposure, as well as the data available in the literature, allow us to put forward suggestions about the supramolecular mechanism of homeostasis regulation, in particular, thiol homeostasis regulation in such high-protein structures as the lens, which can be realized by aggregation-disaggregation of protein molecules (crystallins in the case of the lens). Our results can serve as a basis for developing a new non-invasive approach to cataract prevention using low-intensity microwave radiation.

Published: July 2023

The effects of amitriptyline (10 mg/kg), melipramine (10 mg/kg), and fluoxetine (5 mg/kg) on the acquisition of conditioned active avoidance responses and their spatial alteration in rats were studied. During the acquisition of avoidance, a passage in the partition was open, adjacent to the rear wall of the shuttle chamber. On the 5th experimental day after the end of the training, this distal opening was closed and the proximal one was opened, after which avoidance performance under changed conditions was tested for 20 trials. Melipramine and amitriptyline accelerated the acquisition of avoidance responses. Changing the location of the opening disrupted the learned skill, especially in the control animals. Melipramine and fluoxetine statistically significantly (in contrast to amitriptyline) accelerated the recovery of the level of avoidance. The positive effect of melipramine and fluoxetine is explained by a psychostimulating component in their spectrum. The inability of amitriptyline to produce a significant effect in this model is due to its psychosedative properties. The data obtained allow us to conclude that the acquisition of the active conditioned avoidance responses and their spatial modification can be used to analyze the antidepressant activity of pharmacological agents.
Mobile EEG systems for alpha neurofeedback and anxiety control
Authors: Sultanov M.B. , Ismayilova Kh.Y.
Published: July 2023

The present research is devoted to the study of the relationship between the oscillations of the electroencephalography (EEG) bands and the level of anxiety among sixteen youth athletes aged 17–21 using a mobile EEG system. The study explores the oscillations of brain waves in eyes-open and eyes-closed conditions at rest. The EEG was recorded using a wireless EEG Headset System with dry non-contact EEG sensor electrodes designed by NeuroSky, a ThinkGear module, and a MindCap XL headband. The results of the study demonstrated statistically significant differences between eyes-open vs. eyes-closed conditions in the alpha band in the prefrontal cortex (p≤0.006). While the correlation between the alpha band and the state of anxiety in the prefrontal cortex demonstrated a statistically significant linear relationship with the negative slope in the eyes-closed condition (p≤0.029). The data derived from single-channel wireless system equipment demonstrated results that are close to those recorded by conventional lab-based equipment. The different nature of the interrelation between the EEG alpha band oscillations in the prefrontal cortex, depending on the position of the eyes and the level of anxiety of youth athletes, can reflect its relationship to the "inner" world of the individual and is a plausible neurobiological index of anxiety. These findings encourage the application of the portable EEG system for the research of brain functions. Even more, that device may be used for alpha neurofeedback for anxiety in closed-eye conditions.

Se realizó un estudio cuyo objetivo fue realizar una descripción histórica de la educación policial para la policía en Colombia, para lo cual como método se realizó una revisión de textos históricos sobre la Policía Nacional y normatividad colombiana sobre la educación policial en el siglo xx y xxi. Como resultado, se pudo apreciar que pasó de una concepción de un oficio enteramente pragmático que no requería ningún tipo de estudio formal a la idea paulatina de la profesión policial en donde los policías tenían que pasar por una escuela de formación y posteriormente capacitarse y especializarse para asumir sus labores diarias en las distintas direcciones del servicio. El nivel formativo de los policías y el paso a la educación formal estuvo de la mano de la evolución histórica de la educación en Colombia y de exigencias en respeto de los Derechos Humanos. En conclusión, se ha recorrido un largo proceso en donde los policías nacionales han pasado del pragmatismo en temas educativos a la profesionalización en cuanto a procesos de educación formal, formación continua, entrenamiento y reentrenamiento para el servicio.

Revisiting Balassa-Samuelson Hypothesis for Asia – A Critical Appraisal of Literature
Authors:   The University of Lahore, Ishaq Maryam , Puime-Guillén Félix ,   University of A Coruña, Fernández-González Raquel ,   University of Vigo, Duda Joanna ,   AGH University of Krakow
Published: July 2023

Purpose: The present study is aimed at presenting a critical appraisal of the empirical literature on the Balassa-Samuelson hypothesis for emerging and developing Asian countries. Design/methodology/approach: A critical appraisal of the relevant studies is carried out across various important dimensions of the empirical estimation of the Balassa-Samuelson hypothesis including the scheme of sectoral division followed, definitions and proxy variables used for constructing real exchange rate and price series, choice of output and employment series and their subsequent transformation, empirical methodology followed and (theoretically) different variants of the hypothesis chosen for empirical estimation. Findings: Only a handful of studies have investigated the Balassa-Samuelson hypothesis for Asia. Nevertheless, these studies are characterized by a variety of irregularities in dealing with different important features of the theory, which may be of critical importance for yielding consistent empirical estimates. In multi-country studies for Asia, serious inconsistencies are observed whilst handling these critical aspects of the hypothesis. Such irregularities may hold serious implications for model estimates since the empirical evidence from Asia is very mixed, and in many cases, not even robust. Practical implications: The inconsistencies highlighted in this review paper hold strong implications for future research in this area. The selection of price indicators for the construction of real exchange rate series, choice of econometric methodology and the theoretical framework followed are aspects of the empirical verification of the Balassa-Samuelson hypothesis that need to be handled with great caution since they turn out to be most sensitive in relation to yielding intuitively correct and robust model estimates. Originality: To our knowledge, so far, no study on Asia has presented such an extensive appraisal of literature on the productivity-real exchange rate nexus. The present study is therefore novel in the sense that it critically evaluates studies on Asia against all those features of the Balssa-Samuelson theory which may stand responsible for yielding mixed and even contrasting empirical estimates for Asia.

From actin waves to mechanism and back: How theory aids biological understanding
Authors: Beta Carsten , Edelstein-Keshet Leah , Gov Nir , Yochelis Arik
Published: July 2023

Actin dynamics in cell motility, division, and phagocytosis is regulated by complex factors with multiple feedback loops, often leading to emergent dynamic patterns in the form of propagating waves of actin polymerization activity that are poorly understood. Many in the actin wave community have attempted to discern the underlying mechanisms using experiments and/or mathematical models and theory. Here, we survey methods and hypotheses for actin waves based on signaling networks, mechano-chemical effects, and transport characteristics, with examples drawn from Dictyostelium discoideum, human neutrophils, Caenorhabditis elegans, and Xenopus laevis oocytes. While experimentalists focus on the details of molecular components, theorists pose a central question of universality: Are there generic, model-independent, underlying principles, or just boundless cell-specific details? We argue that mathematical methods are equally important for understanding the emergence, evolution, and persistence of actin waves and conclude with a few challenges for future studies.
An effective digital image watermarking scheme incorporating DCT, DFT and SVD transformations
Authors: Varghese Justin , Bin Hussain Omer , Subash Saudia , T. Abdul Razak
Published: July 2023

Image watermarking prevents copyright infringements by attaching visible/invisible watermark images as authentication identities in the owner’s documents. The article made analysis on the advantages of different transformations for choosing better combinations to make the watermark embedding process and observed that watermarking techniques incorporating discrete cosine transform (DCT) provide better resistance towards JPEG based potential attacks, discrete Fourier transform (DFT) has strong energy compaction with geometrical invariance properties to resist geometric attacks while singular value decomposition (SVD) provides stability, proportion invariance and rotation invariance properties and it provides strong resistance against noise based attacks. Considering these advantages of different transformations, the article presents a new non-blind watermarking algorithm by utilizing advantages of DFT, DCT and SVD transforms while attaching secret contents in cover images. The algorithm starts by applying DFT followed by onion peel decomposition (OPD) for decomposing Fourier domain carrier image to four frequency sub images. The scheme then applies DCT on the frequency bands and orders them in zigzag fashion to form four individual frequency arrays. In the final step of embedding process, it embeds four copies of watermark singular value contents in DFT domain with the carrier image singular value contents to produce the watermarked image. The experimental results based on subjective and objective metrics on various test images from standard image databases with different test conditions demarcate the stability of new algorithm in producing high quality watermarked images with fewer distortions even when the watermarked images are extremely distorted by potential attacks.
Role of microRNA miR171 in plant development
Authors: Pei Ling Ling , Zhang Ling Ling , Liu Xin , Jiang Jing
Published: July 2023

MicroRNAs (miRNAs) are endogenous non-coding small RNA with 19–24 nucleotides (nts) in length, which play an essential role in regulating gene expression at the post-transcriptional level. As one of the first miRNAs found in plants, miR171 is a typical class of conserved miRNAs. The miR171 sequences among different species are highly similar, and the vast majority of them have both “GAGCCG” and “CAAUAU” fragments. In addition to being involved in plant growth and development, hormone signaling and stress response, miR171 also plays multiple and important roles in plants through interactions with microbe and other small-RNAs. The miRNA functions by regulating the expression of target genes. Most of miR171’s target genes are in the GRAS gene family, but also include some NSP, miRNAs, lncRNAs, and other genes. This review is intended to summarize recent updates on miR171 regarding its function in plant life and hopefully provide new ideas for understanding miR171 function and regulatory mechanisms.

Os primeiros anos de atuação na docência são permeados por tensões e aprendizagens e tornam-se mais desafiadores quando a inserção ocorre na alfabetização, devido à complexidade e especificidade desse processo. Este artigo, de caráter qualitativo, teve como objetivo desvelar o processo de inserção à docência na alfabetização de professoras egressas de um Curso de Pedagogia. A análise dos dados indica que os desafios encontrados estão relacionados às condições decorrentes do contexto de atuação: escola privada ou pública. Na escola privada, dizem respeito ao engessamento da ação pedagógica e a autoconfiança e confiança das famílias; na escola pública, à quantidade de crianças, heterogeneidade do grupo e, à falta de apoio. Independentemente do contexto, este tem sido um processo solitário que necessita de acompanhamento intencional.

Neste trabalho, apresentamos algumas discussões quanto à percepção docente sobre o Projeto Político Pedagógico, o qual é pensado para organizar o trabalho docente e coordenar as atividades pedagógicas de um estabelecimento de ensino. Porém, sua concepção normativa não é aquela captada pelos professores em exercício, mostrando seu aspecto dinâmico, não estacionário. Verificamos, em uma pesquisa exploratória através de questionário impresso, aplicado a professoras de uma escola confessional, da rede privada, por meio de uma análise temática, que as docentes adaptam sua percepção do documento a sua formação inicial, adaptando-se para a prática pedagógica mesmo que o documento explicite pontos que poderiam contradizer esta formação, sobretudo no campo teórico, o que nos permite inserir a ação do documento no plano empírico da prática escolar.

Cholesteric liquid crystals (CLCs) are becoming increasingly popular due to their unique chiral structural color. Unlike ordinary CLCs materials, CLCs particles exhibit angle‐independence, making them particularly noteworthy. However, currently, there are limited effective methods for controlling the structural color of CLCs particles, other than adjusting the concentration of chiral dopants or introducing stimuli‐responsive groups. Here, a scalable and cost‐effective process for preparing monodisperse CLCs particles via dispersion polymerization is reported. By making CLCs into micrometer‐sized monodisperse spheres, the helical pitch of CLCs can be varied according to its particle size, and the resulting structural color hue due to Bragg reflection can also be changed. Covering the CLCs particles with polydimethylsiloxane results in the formation of a polymer dispersed liquid crystals–like structure, which enhances the structural color appearance and thermal stability of the CLCs particles. Additionally, a simple strategy to produce chiral anti‐counterfeiting QR codes is developed. By combining CLCs particles with commercially available pigments, an anti‐counterfeiting QR code that can only be displayed under a specific circular polarizer is created. This approach and resulting CLCs particles expand the modulation of CLCs structural color and enrich the application of structural color in the field of chiral optical anti‐counterfeiting.

Stretchable electronic devices, with their excellent properties such as stretchability and conformal contact with complex surfaces, are widely used in health monitoring and human‐computer interactions. For stable operation of these devices, stretchable circuits are crucial, enabling integration of sensors, data collection, and transmission while under strain. To achieve stretchable system integration, addressing key issues such as elastic substrates, sensor devices, rigid components, stretchable electrodes, and packaging layers is necessary. The stretchable electrodes, which connect various functional devices, are crucial for achieving stretchability and are the main focus of this review. Firstly, this work explores the enhancement of electrode design to maintain good electrical conductivity even under stretching conditions, through studying stretchable conductive materials and the structural design of conventional materials. This work then presents studies on substrate interfaces and the design of elastic substrates, such as rigid islands, to enhance the stability of stretchable circuits during use. Finally, the article discusses the applications of stretchable circuits, the challenges they face, and provides new research directions and ways to develop stretchable circuits.

Dermatitis herpetiformis (DH) is an inflammatory skin disorder often considered as an extra intestinal manifestation of celiac disease (CeD). Hallmarks of CeD and DH are auto‐antibodies to transglutaminase 2 (TG2) and transglutaminase 3 (TG3), respectively. DH patients have auto‐antibodies reactive with both transglutaminase enzymes. Here it is reported that in DH both gut plasma cells and serum auto‐antibodies are specific for either TG2 or TG3 with no TG2–TG3 cross reactivity. By generating monoclonal antibodies from TG3‐specific duodenal plasma cells of DH patients, three conformational epitope groups are defined. Both TG2‐specific and TG3‐specific gut plasma cells have few immunoglobulin (Ig) mutations, and the two transglutaminase‐reactive populations show distinct selection of certain heavy and light chain V‐genes. Mass spectrometry analysis of TG3‐specific serum IgA corroborates preferential usage of IGHV2‐5 in combination with IGKV4‐1. Collectively, these results demonstrate parallel induction of anti‐TG2 and anti‐TG3 auto‐antibody responses involving separate B‐cell populations in DH patients.

Published: July 2023

Bei Bestrahlung können Racemate in Gegenwart eines geeigneten chiralen Katalysators in enantiomerenreine Verbindungen mit gleicher Struktur umgewandelt werden. Dieser Prozess wird photochemische Deracemisierung genannt und beinhaltet die Bildung kurzlebiger Intermediate. Das Eröffnen unterschiedlicher Reaktionswege für die Vorwärtsreaktion zum Intermediat sowie für die Rückbildung des chiralen Moleküls ermöglicht diesen entropisch ungünstigen Prozess. Seit der Entdeckung der ersten photochemischen Deracemisierung im Jahr 2018 hat sich das Forschungsgebiet rapide entwickelt. Die vorliegende Übersicht beinhaltet die in diesem Bereich durchgeführte Forschung und diskutiert aktuelle Entwicklungen. Sie wurde unterteilt gemäß der Art der Differenzierung und den jeweiligen Substratklassen. Der Schwerpunkt dieser Übersicht liegt auf der Substratpalette einzelner Reaktionen und auf einer Diskussion der mechanistischen Details, die der vorgestellten Reaktion zugrunde liegen.
Tracheobronchopathia osteochondroplastica: a rare cause of tracheal tube cuff leak
Authors: Morax L. S. , Breitenmoser I. , Konrad C. J.
Published: July 2023

We present the case of a patient with the rare disorder tracheobronchopathia osteochondroplastica who underwent laparoscopic cholecystectomy. After induction of general anaesthesia, we faced difficulties passing the tracheal tube beyond the vocal cords despite bronchoscopic assistance. With a smaller tube, and by using rotating movements, we managed to successfully intubate the trachea. Because of the irregular tracheal surface, however, ventilation was challenging due to a massive cuff leak. Repeated repositioning did not improve this leak. Only cuff overinflation led to adequate ventilation, though we were cognisant of the increased risk of tracheal wall injury with this approach. After completion of the surgery, the patient's trachea was extubated without complication. This case showed that even with good preparation, intra‐operative problems can occur with abnormal subglottic airway anatomy. In some circumstances, these problems can only be solved by compromise. There are no professional consensus or guidelines that can be followed as guiding references for such a case, which can lead to indecisiveness.
Revisiting to N‐alkylation of multi‐dentate amines ligand for ATRP

The ligands role in normal atom transfer radical polymerization (ATRP) is not only for controlling the system but also regulate the rate of polymerization depending the solubility in the reaction media. Solubility of the catalyst/ligand complexes in organic media is of particular importance to attain homogeneous polymerization conditions. The linear multi‐dentate amine ligands with a long aliphatic chain on the nitrogen atoms provide solubility of its metal complexes in organic solvents. However, the increasing length of the alkyl substituents induces steric effects and can alter the redox potential of the metal center. Herein, to understand the effect of alkyl length, we report the synthesis of tri‐, tetra‐dentate linear amine ligands, diethylenetriamine, triethylenetetramine having n‐alkyl halides containing odd carbon chain lengths (C3H7‐, C5H9‐), respectively. Well‐defined polymers were obtained in ATRP of S and MMA using synthesized ligands. Apparently, increasing the alkyl chain length was sufficient to provide homogeneous ATRP medium, which was not achieved with methyl‐substituted ligands (e.g., pentamethyldiethylenetriamine, PMDETA and hexamethyltriethylenetetramine, HMTETA). In combining ATRP results for odd (synthesized) and even carbon number alkylated ligands (literature), linear decreasing trend was observed on apparent rate constant (kpapp) by the increasing the alkyl chain length.
