M-BANKING E O PÚBLICO DO MICROCRÉDITO:
Authors: De Oliveira e Souza Allanison Jose
Published: February 2024

Objetivo: Pequenos empreendedores têm dificuldade de acesso ao crédito, mas podem ser atendidos com linhas de microcrédito através de canais digitais, como o mobile banking (mb). O presente estudo teve como objetivo medir o impacto de fatores antecedentes (expectativa de desempenho, expectativa de esforço, influência social, condições facilitadoras, motivação hedônica, relevância do preço e hábito) na intenção e no comportamento de uso do mb pelo público do microcrédito urbano, e identificar se a relação entre intenção e uso é moderada por fatores como idade, gênero e experiência. Design / metodologia / abordagem: Uma survey foi aplicada e contou com 470 respondentes, pequenos empreendedores com renda até R$200 mil. Para a análise dos dados foi utilizada a técnica de modelagem de equações estruturais para o teste de hipótese e AFC para avaliar a validade convergente e precisão do modelo de mensuração. Resultados: Os resultados encontrados foram que o hábito, as condições facilitadoras e a influência social influenciam positivamente a intenção de uso do mb. Além disso, a intenção de uso é um forte preditor do comportamento de uso do mb e essa relação pode ser moderada pela experiência do usuário, ou seja, quanto mais experiências o pequeno empreendedor tiver, mais propenso ele será a incorporar o comportamento de uso do mb.Originalidade / valor: entender os fatores que influenciam a intenção e o comportamento de uso do mb pelo público do microcrédito urbano é essencial para atuar na resolução de entraves e geração de estímulos por parte das instituições financeiras e de fomento ao desenvolvimento.

ANALYSIS OF THE INSTITUTIONAL MISSION AND CONSTITUENT STRATEGY OF THE FEDERAL INSTITUTES OF EDUCATION, SCIENCE AND TECHNOLOGY IN BRAZIL
Authors: Alves Lindomar Júnior Fonseca , Diehl Carlos Alberto , Vargas Sandra Belloli de
Published: February 2024

Objective. Examine the institutional mission statement and constituent strategy of the Federal Institutes of Education, Science and Technology in Brazil.
Design/method/perspective. The study is descriptive with a qualitative approach. We used the model presented by Pearce and David (1987) regarding the effectiveness of the mission model. We separated the research approach into two groups. First, we linked to hermeneutic analysis. The second group deals with the mission statement's effectiveness by identifying the elements.
Results. We evidenced the low presence of the elements recommended by Pearce and David (1987), not even reaching half of the elements defined in the model. The normative aspects are, in percentage, the most addressed.
Practical implications. There is a significant gap between what someone advocated in the Federal Institutes' mission statements and the strategy that gave rise to their creation.
Originality/value. The originality of this article lies in the selection of educational institutions analysed since there is a significant volume of studies focused on higher education institutions but not on the complete set of Federal Institutes. Another distinctive aspect of this research concerns the analysis of the alignment of the mission statements with the strategy that gave rise to the creation of the Federal Institutes, the expansion, the internalisation and the increment of professional and technological education.

Három MEFESZ a 20. századi magyar történelemben
Authors: Jancsák Csaba
Published: February 2024

The Association of Hungarian University and College Students (AHUCS, MEFESZ) was founded on 16 October 1956 at the University of Szeged. In the Hungarian history of the second half of the 20th century, the acronym ‘MEFESZ’ appeared three times (1945: Alliance of Hungarian University and College Associations AHUCA, MEFESZ; 1948: Unified Organization of Hungarian University and College Students, AOHUCS, MEFESZ and 1956: AHUCS, MEFESZ). In all three cases, the organisations were actors in the field of youth and education. The short history and existence of the three MEFESZ has many lessons to teach us. Although the three organisations’ names were identically abbreviated, the full form of their names differed, and so did their aims and roles. In this paper, we show that the 1956 MEFESZ is not a successor of the two earlier organisations, MEFESZ in the period of ‘tentative democracy’ (1945–1948) and in the first period of communist dictatorship (1948–1950). The 1956 MEFESZ – the focus of our study – was a new grassroot initiative and became the precursor of the revolution in the same year. In its aims, organisational structure and political programme, it was grounded in democratic principles. The political demands of the programme of the MEFESZ that had been adopted on 20th October 1956 became the demands of the revolution on 23rd October. An analysis of the basic and operational principles of the 1956 MEFESZ and the elements of its political programme show that its ‘organisational personality’ and its world of values represented the trans-historical social democratic values of universities: freedom of opinion, thought and expression, autonomy, solidarity, subsidiarity, self-government and the participation of young people in decision-making.
Ültetvényesek és kisgazdák a Texasi Köztársaságban
Authors: Kökény Andrea
Published: February 2024

On April 21, 1836 the Texas Army defeated the Mexican troops at the battle of San Jacinto and captured its commander-in-chief, Antonio López de Santa Anna. The Mexican president was forced to acknowledge the independence of the Texas Republic. During and after the war of independence thousands of Americans moved to Texas in search of economic opportunities. The number of European immigrants also started to grow. Among them the German settlers made up the largest ethnic group by the middle of the 19th century. This essay aims to examine the characteristics of the German colonies in Texas and analyze the role of Carl Solms-Braunfels and John O. Meusebach in the foundation of New Braunfels, Fredericksburg and other German settlements. To honor the memory of József Sipos and his research activity and teaching career, the emphasis is on the economic development of the state and the expansion of the plantation system and smallholder agriculture.
A földközösség újjáéledése az Alföldön a 18. században
Authors: Marjanucz László
Published: February 2024

The major issue of the territories liberated from the Turks was the resettlement of the destroyed villages and the establishment of a new hierarchy of the settlements. For the individual and family settlers a whole new range of possibilities opened not bound neither by territorial nor by residential issues. Since there were few settlers and plenty of land, a borderland use based on the idea of free land occupation was developed, which did not allow the formation of a real community. However, the arrival of more settlers resulted in the increase of the number of claimants for land. It was not long before the system of free land occupation had led to confusion and disputes. The solution was to limit the rights of the individual and to cultivate a habit of settling disputes together. First, the freedom of ownership (occupation of land at will) was restricted. The system of common land was born out of this era of sporadic settlement, with its new form of land use regulation. At this level, the village collectively decided how the borderland should be divided and used. In other words, they swapped to a three-field system. By the time the landlord appeared in the villages in the 18th century, an arrangement had already been established and finalized in its new form by the peasantry. The initial balance of mutual dependence (the acceptable weight of the landlord’s burden and the sure collection of the landlord’s due) was tipped by the landlord’s increasing financial interest, which instead of the annual reallocation of the land placed the emphasis on the formation of the plot of land, a kind of permanent individual ownership. Thus, the very essence of the common land, the regulation of ownership ceased, and only the three-field system remained from the era of communal land use
A dombrádi „telepesekről”
Authors: Révész Béla
Published: February 2024

From 1949 to 1953, Mátyás Rákosi, the Hungarian communist dictator was nearly all-powerful. His Stalinist political leadership in 1951 started a campaign of internment of people who were considered enemies of the state. The internment camps were established in various locations across Hungary, including the village of Dombrád (the birthplace of József Sipos). The internment campaign was part of a larger effort by the Hungarian government to suppress dissent and opposition of its policies. The government targeted people who were suspected or just claimed to be involved in anti-communist activities or who were deemed to be a threat to the state. In 1951, thousands of middle- and upper-middle class citizens in the capital, even who were only considered to be so, were forcibly transferred to settlements in the countryside. Members of the bourgeoisie, the aristocracy or the old political elite were also considered untrustworthy. Many of them were evicted from their homes, their property was confiscated and they were forced into run-down accommodations, even sent to labour camps. Their apartments and houses were occupied by Communist Party cadres, who immediately got their hands on valuable furniture and works of art. Forced labour camps were also built based on the Soviet model. In the camps around the village of Hortobágy – just as in Dombrád –, displaced persons had to work hard in appalling conditions. They were all called as “class enemies” of the communist system. In July 1953, Rákosi, who had presided over the government as well as the Party since 1952, was deposed from his former office in favour of Imre Nagy. The new prime minister promised a new course: more tolerance in political life, especially towards the intelligentsia and the churches, release of political prisoners and closure of the internment camps. Many of these reforms were really introduced and were welcomed by the people. The study aims to briefly describe these years, focusing on the case of the village of Dombrád.
Egy tábornok Szegedről
Authors: Szakály Sándor
Published: February 2024

One of the well-known Hungarian military leaders of the Interwar Era, Lieutenant General Vitéz Dr. Kálmán Shvoy (1881–1971) spent most of his life in Szeged and eventually became one of the recognized residents of the city. His “secret diary and memoir” – which partly evokes his military career – made a huge splash in the 1980s and is still heavily referenced today. But who was Kálmán Shvoy actually? How did his military career evolve? What did he accomplish as a soldier that justified his inclusion among the top military leadership of the era? To what extent did his 1919 “Szeged endeavors” and departure – as an officer in the National Army and later as chief of the general staff of higher commands – propel or hinder his advancement? What was his life like after retirement? How did his military – and in part political – career come to an end? Why was he accused of writing anonymous, libellous and defamatory letters, against which he had to defend himself in court? Why was he acquitted of the charges after 1945, at a time when the men of the “criminal justice system” believed that anyone who had “clashed” with the prominent members of the earlier system had ultimately behaved righteously and thus deserved to be praised?
Dr. Kószó István belügyi államtitkár életpályája
Authors: Tóth István
Published: February 2024

István Kószó was party president, lawyer, secretary of the interior ministry, notary, also famous citizen of Szeged, however, his life story is still unknown after hundred years. In his time, at the turn of the 19th and 20th centuries, he was a wellknown person in the city of Szeged, and also in the region. This article focuses mainly on his political career, because prof. Dr. József Sipos was more interested in this aspect of Kószó’s life. His nationwide political career started in 1917, during the Great War, when he became a member of parliament. After the war and during the chaotic period, he came back to Szeged to work again as a lawyer. It proved to be a good choice, as the base of the counterrevolution moved to Szeged during this time and he was able to make contact with the leading political figures (like Miklós Horthy, Pál Teleki, István Bethlen). In the 1920’s, he made a national political career with the help of these contacts. The article also focuses on the titles he received or wanted to obtain, how he won the MP elections in Szeged, on his alleged antisemitism, and whether he should have retired from the parliament, from the ministry. I will also examine his associations in Szeged, where he was president, vice-president and honorary president. The article is dedicated to prof. Dr. József Sipos, to our teacher, who passed in 2021.
Johan Béla és a modern magyar közegészségügy kiépítése
Authors: Cora Zoltán
Published: February 2024

The relationship between the Horthy era (1920–1944) and the communist era shows continuities if it is examined from a social historical perspective. The paper contributes to the reinterpretation of these relations by looking at Hungarian health care in the 1930s and 1940s with a focus on the relationship between international transfers and path dependency in forging health care reforms. I argue that the achievements communists regarded as inventions of socialism in health care and the welfare state had already been developed thoroughly in the 1930s and 1940s. It was only because of the strict wartime budget of the early 1940s that these welfare reforms had not been realised. With the help of internal affairs documents, essays on health care, and official statistics records in the National Archives of Hungary and the Semmelweis Library and Archives of Medical History in Budapest as well as press material, I demonstrate that, even if communists depicted the interwar period as “fascist and imperialist”, the health care system of the so-called “productive social policy” showed continuities. Moreover, social policy makers of the 1930s and early 1940s, such as Béla Johan, Ferenc Keresztes-Fischer and Béla Kovrig, also designed welfare and health care reforms for the post-war period by both developing already existing Hungarian programmes and selectively adapting foreign welfare models (American management principles, the Alsace scheme, and the Beveridge Plan). The study investigates Hungarian health care in view of the theory of path dependency and the macrohistorical convergence thesis developed by Béla Tomka (on the question of East-West convergence). It is within this framework that the paper addresses the issue of health care transfers to better understand the development of 20th -century European health care systems by identifying similarities and differences in their development as well as to speculate on the trajectory of various political solutions to social challenges, including health care.

Az esszé a transz gyerekkor megengedő értelmezési kereteit vizsgálja. Értelmezésemben a gyerekkor markerei az életkor, a társadalmi közeg, és a tranzíció. A gyerekkor tehát olyan tág fogalomként definiálódik, mely a poszt-adoleszcenciát, azaz a középiskolát követő éveket is magában foglalja. Ugyanakkor szituatív is, hiszen a családban, a generációk közti kapcsolatban akár felnőttkorban sem oldható fel a gyerekszerep. Továbbá a felnőttkorban megélt tranzíciók többek közt a hormonkezelések hatására megismételt kamaszkorral járnak. A transzneműség és a gyereklét összefüggéseit elsősorban magyar popkulturális jelenségek révén tárom fel. Bödőcs Tibor két szkeccsében megjelenik a társadalmi nem ambivalenciája, ahogy az ún. nemváltó óvodásokat övező, propagandisztikusan gerjesztett félelmek is. A kvír vagy transz gyerekkor érintőlegesen ugyan, de felmerül a Vekerdy Tamás, Popper Péter, Ranschburg Jenő hármasához köthető gyerekpszichológiai diszkurzusban is. Bakony Alexa dokumentumfilmje, a Tobi színei (2021) egyedülálló módon mutatja be a vidéki transz kamaszlétet – egyben lehetővé teszi a transz gyerekkor és az arról való beszéd radikális egyidejűségét.
Vizuális napló, autofotográfia: emlékezet és szellemjárás Patti Smith polaroidjain és a közösségi médiában
Authors: Taskovics Viktória
Published: February 2024

Patti Smith (1946- ) amerikai író, költő, zenész, képzőművész munkásságában a fotográfia mint médium, látásmód és narratív toposz kiemelt jelentőséggel bír. A Horses (1975) című debütáló lemezével világszerte ismertté vált alkotó a rock’n’roll ábrázolási hagyományait felforgatva radikálisan új, kritikai nézőpontból gondolta újra a hetvenes évek női ideáljának képzetét. Smith különcségére számos fotográfus felfigyelt: Frank Stefanko, Lynn Goldsmith és Annie Leibovitz is számos portrét készítettek róla. Férje, Fred ‘Sonic’ Smith halála után idővel Patti Smith maga is polaroid kamerát ragadott, és fotóalanyból fotográfussá lépett elő. Fotográfiai munkássága elsősorban gyászfeldolgozási kísérletként, az őt ábrázoló narratíváktól eltérő, autonóm gesztusként értékelhető. A fotografikus látásmód, a fotó, mint a narratíva szerves kelléke megjelenik minden memoárjában, melyek utazásait, számára meghatározó alkotók, személyek ereklyéit rögzítik, dokumentálják. Kísérteties fotóin az élők és halottak, testek és tárgyak, hiány és látomás határai mosódnak egybe. Tanulmányomban arra teszek kísérletet, hogy feltérképezzem azt, hogy a Smith-féle fotografikus látásmód, a nemi viszonyokról való gondolkodás és az önéletírói gyakorlat milyen szerepet töltenek be a traumatapasztalat elbeszélhetővé tétele és az emlékezés folyamatában. Megvizsgálom azt, hogyan ülteti át Patti Smith ezt a praxist a közösségi médiába, és hogy ez a felület miképp alakítja át radikálisan az emlékezéshez és az emlékezet tárgyaihoz való viszonyulást.

Published: February 2024

The metallurgical industry, crucial for the global economy, faces considerable challenges in the casting process, with workers exposed to physical, chemical, and ergonomic risks. This study emphasizes the importance of risk management, utilizing tools such as the Ishikawa Diagram, Pareto Diagram, and GUT Matrix. Regulatory Standards (NRs), like NR 4 and NR 9, play a crucial role in safety by establishing guidelines for specialized services and environmental risk prevention. Risk assessment, essential for the safe operation of the metallurgical industry, involves identifying and controlling potential threats such as high temperatures, hazardous chemicals, and ergonomic risks. Moreover, effective risk management, addressing challenges like dehydration, burns, and intoxication, contributes not only to workplace safety but also to compliance with government regulations and the industry's sustainability. Quality tools like the GUT Matrix, Ishikawa Diagram, and Pareto Analysis are fundamental for optimizing processes and identifying root causes of issues. The Effort X Impact matrix, derived from the GUT Matrix, allows prioritizing actions, focusing efforts where they are most needed. In conclusion, risk analysis and the implementation of preventive measures are essential to ensure safe working environments, comply with regulations, and promote operational efficiency in the metallurgical industry.
The Politics of Modernity: the Discourse of the Westphalian System toward the Native in Indonesia
Authors: Maliki Musa , Prihatiningsih Witanti
Published: February 2024

Modernity is a large concept that can be found in many disciplines, such as philosophy, history, sociology, anthropology, political economy, and International Relations (IR). One of many significant infrastructures of modernity is the concept of nation-states, the definition of which can also be found in the aforesaid disciplines. This article will elaborate on the concept of modernity concerning relations between nation-states and non-nation-states such as native local communities in which rooted in those multi-disciplined courses. This article argues that imagined nation-states of the Westphalian system impose, imprison, and marginalize native communities from within. The birth of nation-states in the European Western discourse has created marginalization of native communities around the world. Using some examples of Indonesian natives, this article shows that modernity is political. The politics of modernity either instrumentalized or marginalized and forced the Indonesian natives to obey the standardization of the Indonesian Westphalian system. As a result, since the Dutch colonialization up to now, the Indonesian natives have not yet embraced full citizenship rights because they are marginalized, subjugated, and discriminated against politically, economically, and socially.

We present a case of a preterm neonate with a type IV laryngo-tracheo-oesophageal cleft, an uncommon congenital malformation, resulting from the failure of separation of the trachea and the oesophagus during fetal development, often associated with other deformities as well. Data in the literature shows that the long-term morbidity from the entity has declined over the last decades, even though prognosis remains unfavourable for types III and IV. This report emphasizes the complex issues neonatologists are faced with, when treating neonates with this rare disorder in the first days of life, what will raise suspicion of this rare medical entity, and that direct laryngoscopy/bronchoscopy finally depicts the exact extension of the medical condition. At the same time extensive evaluation for coexisting congenital anomalies should be performed. For all the above reasons, these neonates should be treated in specialized tertiary pediatric centers for multidisciplinary prompt management, which may improve, the outcome.
A Giant Scrotal Neurofibroma in a Child Masquerading as Filariasis: Uncommon Presentation of a Common Disease
Authors: Singh Anurag , Singh Gyanendra , Verma Anuragani , Verma Yogendra Narayan
Published: February 2024

Neurofibroma of the scrotum is a very uncommon benign neoplasm, specifically when it affects teenagers and is not associated with neurofibromatosis type I. To the best of our knowledge, only a couple of cases of neurofibroma in children have been documented. Here, we report a case study of a 17-year-old boy who had a giant scrotal lump for ten years masquerading clinically as filariasis. A provisional diagnosis of benign nerve sheath neoplasm was made based on cytology findings. The lump was surgically removed from the patient, and a histopathological and immunohistochemistry examination established the diagnosis of neurofibroma. The combined clinical, preoperative cytological, histological, and immunohistochemistry findings were not presented in the literature in any of the formerly documented cases of scrotal neurofibroma. The current case expands the spectrum of differential diagnoses for scrotal tumours that clinicians have previously observed.

Published: February 2024

Takayasu arteritis is a large vessel vasculitis, characterized by granulomatous inflammation of arterial vessels, that typically affects the aorta, its main branches and pulmonary arteries. Disease diagnosis is a challenge and requires awareness of the condition, as clinical signs can be not specific. We report a case of an adolescent with recurrent stroke diagnosed with Takayasu arteritis. A diagnosis of Takayasu arteritis was established due to angiographic findings in the magnetic resonance angiography in conjunction with systolic blood pressure discrepancy, arterial hypertension and increased acute phase reactants. Takayasu arteritis is a rare cause of ischemic stroke in children. However, stroke may be the first manifestation of the disease. Clinical experience and multidisciplinary approach, including aggressive treatment, is essential for the favourable outcome of the disease and the reduction of the associated morbidity and mortality.

Published: February 2024

A middle-aged man in his 50s, active smoker, presented to the pulmonary office for lung cancer evaluation. On a low-dose computed tomography for lung cancer screening, he was found to have an 8 mm endobronchial lesion in the right main stem bronchus. A PET-CT revealed no endobronchial lesion, but incidentally, fluorodeoxyglucose (FDG) avidity was present in the right hilar (SUV 13.2) and paratracheal lymph nodes (LNs). He underwent bronchoscopy and EBUS-TBNA of station 7 and 10 R LNs. The fine needle aspiration (FNA) revealed necrotizing epithelioid granuloma. The acid-fast bacilli (AFB) and Grocott methenamine silver (GMS) stains were negative. He had suffered from pneumonic tularemia 13 months ago and immunohistochemical staining for Francisella tularensis on FNA samples at Center for Disease Control and Prevention was negative. The intense positron emission tomography (PET) avidity was attributed to prior tularemic intrathoracic lymphadenitis without active tularemia, a rare occurrence. To the best of our knowledge, PET-positive intrathoracic lymph node beyond one year without evidence of active tularemia has not been previously reported.

Authors: Wattanapisit Apichai , Pankamnerd Natthawan , Wattanapisit Sanhapan
Published: February 2024

Chronic abdominal pain is a challenging problem in clinical practice, with several pathophysiological mechanisms underlying its aetiologies. This case report presents a geriatric patient with multiple comorbidities who had experienced intermittent abdominal pain for over 10 years. Alarming symptoms were ruled out, and a functional gastrointestinal disorder was determined as the most likely cause. The patient’s medical history and previous treatments were thoroughly reviewed, revealing that long-term use of metformin and an oral iron supplement was the iatrogenic symptom triggers. The abdominal pain resolved upon discontinuation of these two medications. This case report highlights the significance of reviewing iatrogenic causes and periodically assessing chronic medical conditions to identify potential contributing factors of chronic abdominal pain.

Published: February 2024

Pepper (Capsicum sp.) is one of the most widely used food worldwide. To assess the magnitude and extent of genetic variability among some chili accessions and varieties, and their contributions to yield, a field experiment was conducted using 30 genotypes during the off-season period from November 2016 to May 2017 under irrigation. The experiment was conducted using an RCBD design with three replicates. Analysis of variance (ANOVA) showed highly significant differences for all traits tested, except for fruit girth, pedicel length, and plant height. Primary branch per plant, dry fruit yield per plot, fruit length, stem width, and number of fruits per plant all had high GCV(genotype coefficient of variation) and PCV(phenotypic coefficient variation) values among the yield components, along with high heritability and genetic advance as a percentage of the mean. For all traits, the phenotypic coefficient of variation was higher than the genotypic coefficient of variation, indicating an environmental influence on these traits. High heritability, along with high genetic advance as a percentage of mean, was observed for primary branch per plant, stem width, fruit length, number of fruits per plant, and dry fruit yield per plot, implying the potential for crop improvement in chilli through selection.

Published: February 2024

Studying the effects of maternal iron deficiency anemia (IDA) is complex owing to its diverse causes, each independently impacting the placenta and fetus. Simple treatment with iron supplements does not always resolve the anemia. Therefore, delving into how IDA alters placental development at a molecular level is crucial to further optimize treatment. This review addresses the effects of IDA on placental structures and functions, including changes in oxygen levels, blood vessels, and the immune system. Profound understanding of physiological characteristics and regulatory mechanisms of placental development is key to explain the mechanisms of abnormal placental development in pregnancy-associated disorders. In turn, future strategies for the prevention and treatment of pregnancy complications involving the placenta can be devised. These studies are significant for improving human reproductive health, enhancing sociodemographic qualities, and even lifelong wellbeing, a focal point in future placental research.

Interferon induced transmembrane proteins (IFITMs) play a dual role in the restriction of RNA viruses and in cancer progression, yet the mechanism of their action remains unknown. Currently, there is no data about the basic biochemical features or biophysical properties of the IFITM1 protein. In this work, we report on description and biochemical characterization of three conformational variants/oligomeric species of recombinant IFITM1 protein derived from an Escherichia coli expression system. The protein was extracted from the membrane fraction, affinity purified, and separated by size exclusion chromatography where two distinct oligomeric species were observed in addition to the expected monomer. These species remained stable upon re-chromatography and were designated as “dimer” and “oligomer” according to their estimated molecular weight. The dimer was found to be less stable compared to the oligomer using circular dichroism thermal denaturation and incubation with a reducing agent. A two-site ELISA and HDX mass spectrometry suggested the existence of structural motif within the N-terminal part of IFITM1 which might be significant in oligomer formation. Together, these data show the unusual propensity of recombinant IFITM1 to naturally assemble into very stable oligomeric species whose study might shed light on IFITM1 anti-viral and pro-oncogenic functions in cells.

A comprehensive review of oral chitosan drug delivery systems: Applications for oral insulin delivery
Authors: Alfatama Mulham , Choukaife Hazem , Alkhatib Hamzeh , Al Rahal Okba , Zin Nur Zahirah Mohamad
Published: February 2024

Pharmaceutical scientists have long struggled to develop reliable and efficient systems of administering insulin orally due to multiple barriers, including stomach acidity, enzymatic degradation, and mucus barriers. However, various strategies were developed to avoid insulin degradation in the gastrointestinal tract (GIT) and promote membrane permeability and biological activity. Among these strategies, chitosan polymer-based carriers are widely researched due to their ability to protect insulin in the alimentary canal and deliver it effectively through the intestinal mucosa, improving its bioavailability. To improve chitosan properties, chemical and physical modifications have been developed, and recently, nanoparticles, microparticles, and beads of chitosan exhibited potential systems for oral insulin delivery (OID). This review facilitates an outline of the types of diabetes mellitus, insulin biosynthesis, and gastrointestinal barriers against oral insulin. Moreover, the limitations of subcutaneous insulin delivery and alternative routes of administration are also discussed. As an ideal and most convenient oral administration route, the challenges of safe insulin delivery through the GIT and strategies to elevate its bioavailability are highlighted. In addition, this review focuses on recent advancements in chitosan based carriers for OID and their potential future applications.

The aim of this study is to improve soil fertility in cassava, corn, and peanut plants by using biochar technology on degraded land. This research is experimental. This trial used five treatments, No organic amendments, farm yard manure (FYM) 20 Mg ha−1 once, FYM 20 Mg ha−1 yearly, FYM biochar technology 15 Mg ha−1 once, and cassava stem (CS) biochar technology 15 Mg ha−1 once. The design used in this study was a randomized group design (RAK) with three repeats. Before the experiment, the characteristics of treatment material, namely, the manure, biochar, and CS waste biochar were studied. It was observed that cassava, corn, and peanut crops increased nutrient C, water availability, N, P, K, and cation exchange capacity (CEC). From the observations, the treatment of using biochar technology on intercropping cassava and corn can increase C by 25.7 g kg−1, K by 177 cmol, CEC by 17.63 cmol , and water availability by16.87%. Meanwhile, the application treatment of biochar FYM technology on cassava and peanut intercropping can increase C by 24.4 g kg−1, N by 1.3 g kg−1, P by 12.2 g kg−1, K by 1.74 cmol, CEC by 17.93 cmol, and water availability by 17.41%. The use of biochar technology (15 Mg ha)−1 in intercropping cassava with maize or groundnut within 2 years can improve soil fertility and maintain yields. Intercropping cassava with corn or peanuts within 2 years can increase soil fertility and maintain crop yields. Thus, biochar technology has greater potential for the improvement of degraded land in the relatively short term (2 years) and supports sustainable agriculture.
Atom-bond-connectivity (ABC) indices of graphene sheets, zigzag single walled carbon nanotubes and single walled carbon nanotori

Atom-bond-connectivity (ABC) indices are obtained in analytical forms for graphene sheets, zigzag single walled carbon nanotubes (SWCNTs), and single walled carbon nanotori in terms of number of rings (r) that measures the length and the number of hexagons in between two rings (h) that dictates the width of the concerned systems. The procedures followed for ABC index have been used to obtain the expressions of augmented Zagreb and Randić indices for such systems. Logarithm of ABC indices of zigzag SWCNTs are found to correlate linearly well with the bond dissociation energies per C–C bond and the Young’s moduli of said SWCNTs with fixed number of rings (r) but varying number of hexagons (h) in between two successive rings. The plot of logarithm of ABC index versus Young’s modulus of such SWCNTs in varying both r and h simultaneously is not a straight line but fits well with the sigmoidal (Boltzmann) curve. Wiener index, one of the important distance based index, has recently been found to have similar correlations with the concerned properties of such systems. Similar plots would appear for the said properties of the zigzag SWCNTs with other degree-based indices like augmented Zagreb and Randić indices, as have been indicated from their respective expressions obtained.

Evaluation of the Statistical Significance of a Regression and Selection of the Best Regression Using the Coefficient of Determination R2
Authors: Chanvillard G , Jones JP , Aitcin P-C
Published: February 2024

Statistical methods currently used to analyze experimental data and to select the best-fit regression model are analyzed based on the Fisher F-test. Unfortunately, the judgment of the significance of a regression is often performed by use of the coefficient of determination, available on most calculators. It will be shown that this coefficient of determination can be misused. Two simple equations which take advantage of this coefficient of determination are presented which allow one to analyze the data in an objective manner. The first equation allows one to evaluate the level of confidence of a regression model, and the second equation allows one to evaluate the contribution of a subset of the coefficient to the regression model.
International Development of Standards for Cements
Authors: Jackson PJ , Lawton JM
Published: February 2024

Many cements manufactured and marketed in different countries have generally similar properties, but national standards tend to characterize them using different tests and with different numerical values. A review has been made of the nature and the magnitude of these differences in order to establish those most favored in the world as a whole and also in a number of geographical regions. Greater harmonization of standards for many cements should be possible. Because of its growing acceptance in many countries, a move to the International Standards Organization (ISO) 679 test method for strength could provide a very useful starting point.

Authors: Steiger F
Published: February 2024

In order to obtain quantitative measurements of force, penetration, and energy delivered by rod impact, 25.4-mm-diameter steel rods of lengths of 3.66 m (12 ft), 12.19 m (40 ft), and 23.74 m (77.9 ft) were supported horizontally and struck at one end with a reproducible hammer blow. Force, penetration, and energy values were determined from the measured penetration into a standard material (Oasis floral foam). The data obtained indicate that rod length is a significant factor with respect to penetration and energy delivered.
