New Cationic Gemini Surfactants and Their Use as Dispersants in Oil-in-Water (O/W) Emulsions
Authors: S. O. Kraidi Al.Maliki  , M. J. Kadhim Al.Asadi  
Published: June 2024

In the current research, two types of new cationic gemini surfactants with different spacers (aromatic and heterocyclic) derived from epichlorohydrine were prepared.
The prepared compounds were characterized using FTIR and 1H-NMR spectroscopy. Then the value of critical micelle concentration CMC was calculated using the electrical conductivity and preparing a series of molar concentration of the new surfactants, as well as calculating the balance value between the hydrophilic and hydrophobic (lipophilic) HLB groups.
Cationic gemini surfactants were tasted at different concentration 20-40 ppm by preparing dishes for oil-in-water emulsions determine their dispersion efficiency. It was observed that the dispersant containing the heterogeneous ring (MS1) was more efficiently dispersed than the surfactant containing the aromatic ring (MS2) in the presence of the same hydrocarbon chain and at a concentration of 40 ppm.

The metabolic condition type 2 diabetes mellitus (T2DM) causes organ malfunction and damage due to insulin secretion or resistance abnormalities. The clinical assessment of monitoring short-term blood glucose variability could benefit from the addition of a less interference-prone biomarker for nutritional status and blood cell health. In type 2 diabetic individuals with cardiovascular disease (CVD), this study looks at the significance of serum B-type natriuretic peptide (BNP) and lactate dehydrogenase (LDH) and how it relates to other variables. This study included 100 T2DM patients with cardiovascular disease (57 males and 43 females) with 70 healthy controls (39 males and 31 females ) aged 45 to >74 years with a diabetes duration of 12 to 26 years. the present study shows that in T2DM patients with CVD, there was an increase in Brain Naturiertic Peptide and a high increase in LDH levels. The statistical significance of these differences is very significant (P>0.001). Comparing the patient group to the control group, there is a highly significant increase in BNP and LDH. BNP and LDH were greater in people with type 2 diabetes who also had cardiovascular disease (CVD) and elevated LDH level was associated with elevated BNP. BNP and LDH are useful biomarkers that support diagnosis, and risk assessment, as well as the diagnosis and management of cardiovascular disease in diabetic individuals by facilitating the assessment of heart function and risk factors for cardiovascular disease.

Published: June 2024

Специфической особенностью главного судового дизеля является наличие ограничительной характеристики, защищающей дизель от перегрузки по моменту. При экстремальных режимах крутизна винтовой характеристики возрастает, и автоматика, защищающая дизель от перегрузки, ограничивает диапазон режимов и величину движущей (или тормозящей) силы, создаваемой пропульсивным комплексом. В статье рассматриваются результаты имитационного моделирования экстремальных режимов движения судна – движение в ледяном поле и режим экстренного торможения. В качестве инструмента исследования использована компьютерная модель пропульсивного комплекса танкера ледового класса, оборудованного реверсивным малооборотным дизелем и винтом регулируемого шага. Показана возможность обеспечения оборотов дизеля и упора гребного винта, достаточных для преодоления сопротивления ледового поля путём последовательного уменьшения шага винта. В режиме экстренного торможения судна показана предпочтительность способа торможения путем перекладки лопастей ВРШ по сравнению с применением реверса двигателя и установлена возможность получения минимальных значений времени торможения и выбега судна за счет выбора оптимальной команды на перекладку лопастей ВРШ.
A specific feature of the main marine diesel engine is the presence of a limiting characteristic that protects the diesel engine from torque overload. Under extreme conditions, the steepness of the propeller characteristic increases, and the automation that protects the diesel engine from overload limits the range of modes and the magnitude of the driving (or braking) force created by the propulsion complex. The article discusses the results of simulation modeling of extreme modes of vessel movement - movement in an ice field and emergency braking mode. As a research tool, a computer model of the propulsion complex of an ice-class tanker equipped with a reversible low-speed diesel engine and an adjustable pitch propeller was used. The possibility of ensuring diesel engine speed and propeller thrust sufficient to overcome the resistance of the ice field by successively reducing the propeller pitch is shown. In the mode of emergency braking of a vessel, the preference of the method of braking by repositioning the rotating propeller propeller blades is shown in comparison with the use of engine reverse, and the possibility of obtaining minimum values of the braking time and the vessel's run-out is established by choosing the optimal command to reposition the rotating propulsion propeller blades.

BACKGROUND
At present, liver transplantation (LT) is one of the best treatments for hepatocellular carcinoma (HCC). Accurately predicting the survival status after LT can significantly improve the survival rate after LT, and ensure the best way to make rational use of liver organs.
AIM
To develop a model for predicting prognosis after LT in patients with HCC.
METHODS
Clinical data and follow-up information of 160 patients with HCC who underwent LT were collected and evaluated. The expression levels of alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin, Golgi protein 73, cytokeratin-18 epitopes M30 and M65 were measured using a fully automated chemiluminescence analyzer. The best cutoff value of biomarkers was determined using the Youden index. Cox regression analysis was used to identify the independent risk factors. A forest model was constructed using the random forest method. We evaluated the accuracy of the nomogram using the area under the curve, using the calibration curve to assess consistency. A decision curve analysis (DCA) was used to evaluate the clinical utility of the nomograms.
RESULTS
The total tumor diameter (TTD), vascular invasion (VI), AFP, and cytokeratin-18 epitopes M30 (CK18-M30) were identified as important risk factors for outcome after LT. The nomogram had a higher predictive accuracy than the Milan, University of California, San Francisco, and Hangzhou criteria. The calibration curve analyses indicated a good fit. The survival and recurrence-free survival (RFS) of high-risk groups were significantly lower than those of low- and middle-risk groups (P < 0.001). The DCA shows that the model has better clinical practicability.
CONCLUSION
The study developed a predictive nomogram based on TTD, VI, AFP, and CK18-M30 that could accurately predict overall survival and RFS after LT. It can screen for patients with better postoperative prognosis, and improve long-term survival for LT patients.

Published: June 2024

Abstract: People cannot be separated from their characteristics, including age and education, as they are embedded in the person. These characteristics impact their personalities includinh their psychological empowerment, and attitudes toward change of the people in the organization. This research aims to identify the impact of age and educational level on affective commitment and psychological empowerment. The data were collected from 4 (four) local NGOs in Jakarta, with 113 respondents. The findings of the study revealed that age and educational level positively correlate with affective commitment to change, means that the older the people the higher their score on affective commitment. Further, the higher the level of education of people, the higher score of their affective commitment to change. Meanwhile, there is no significant relationship found between age and education with psychological empowerment. Results can be used for change management, especially in terms of choosing a change leader, which showed that the higher level of education and the older/senior people are more suitable to become the change leader, as they have higher score on affective commitment to change. However, this result cannot be generalized to all types of organizations as the results in various types of organizations were not consistent, and this result based on NGO organizations.

This study aims to determine the impact of the SPW (School for Producing Entrepreneurs) Program and Creative product on the behavioral business and student independence of eleventh-grade students at Binakarya Mandiri, Bekasi, during the 2021–2022 academic year. This study was conducted at Binakarya Mandiri Vocational High School, Bekasi with a population comprising a portion of class XI, to determine the number of samples for each class utilizing cluster sampling data collection techniques to gather 59 students using the Taro Yamane formula. Entrepreneurial interest is the desire to generate business prospects without fear of the associated risks and a desire for entrepreneurial success. Using a pre- and posttest questionnaire, the researchers obtained research data. Prior to receiving support in the SPW program, Creative students' interest in entrepreneurship was assessed using a pretest questionnaire. In the meantime, the posttest questionnaire was used to determine the extent to which students were interested in entrepreneurship after obtaining aid from the entrepreneurial printing school program and the creative and entrepreneurship products field of study. This study employs quantitative descriptive data with a specific percentage utilizing the Azwar scale formula so that the percentage can be determined and results can be stated in words or phrases. According to the data analysis, the findings of the pretest questionnaire, with an average score of 61.90, fall into the moderate group, and the results of the posttest questionnaire, with a score of 79.55, go into the very high category. The results of hypothesis testing indicate that tcount 8.271 > ttable 2.081 at a significance level of 5% with n = 55 and that there is an influence of the entrepreneurial school program and the field of study of creative and entrepreneurial products on the business behavior and independence (interest in entrepreneurship) of students, with the magnitude of the effect being 56%, with the remainder influenced by internal and external factors.

Published: June 2024

Abstract
Quiescent galaxies generally possess denser cores than star-forming galaxies with similar mass. As a measurement of the core density, the central stellar mass surface density within a radius of 1 kpc (Σ1) was thus suggested to be closely related to galaxy quenching. Massive star-forming galaxies with high Σ1 do not fit into this picture. To understand the origin of such galaxies, we compare the spatially resolved stellar population and star formation properties of massive (>1010.5
M
⊙) blue spiral galaxies with high and low Σ1, divided by Σ1 = 109.4
M
⊙ kpc−2, based on the final release of MaNGA integral field unit data. We find that both high-Σ1 and low-Σ1 blue spirals show large diversities in stellar population and star formation properties. Despite the diversities, high-Σ1 blue spirals are statistically different from the low-Σ1 ones. Specifically, the radial profiles of the luminosity-weighted age and Mgb/〈Fe〉 show that high-Σ1 blue spirals consist of a larger fraction of galaxies with younger and less α-element-enhanced centers than their low-Σ1 counterparts, ∼55% versus ∼30%. The galaxies with younger centers mostly have higher central specific star formation rates, which still follow the spaxel-based star formation main-sequence relation. Examinations of the Hα velocity field and the optical structures suggest that galactic bars or galaxy interactions should be responsible for the rejuvenation of these galaxies. The remaining ∼45% of high-Σ1 blue spirals are consistent with the inside-out growth scenario.
Les musiciens d’Église en Bretagne en 1790
Authors: Carbonnier Youri 
Published: June 2024

La base prosopographique Muséfrem, consacrée aux musiciens d’Église actifs en France à la fin de l’Ancien Régime, présente la biographie de 323 individus en Bretagne en 1790. Parmi eux, 224 sont réellement des musiciens, ne se cantonnant pas au plain-chant. La plupart sont originaires de Bretagne, mais un gros quart vient d’autres régions. Certains parcourent de longues distances, inscrivant la Bretagne dans un parcours professionnel complexe, au sein duquel l’attrait salarial joue sans doute un rôle non négligeable. Les femmes musiciennes (toutes organistes) sont, comme ailleurs, très minoritaires et sont nées en Bretagne. Organistes et enfants de chœur constituent les deux fonctions les plus nombreuses, suivies par les musiciens ou chanteurs, puis les instrumentistes. L’un des caractères particulièrement marquants de la Bretagne est l’importance de la place des organistes, qui ne se retrouve guère ailleurs.
Les paroisses rurales bretonnes : quelles réalités musicales ?
Authors: Provost Georges 
Published: June 2024

Dans la continuité des travaux d’inventaire et de recherche sur les orgues menés depuis les années 1980, la présente communication vise à préciser ce qu’il est possible de connaître des pratiques musicales dans les églises des campagnes bretonnes aux Temps modernes. La rareté comme la dispersion des informations dans les archives ont conduit à privilégier deux territoires d’enquête : les actuels départements du Finistère et d’Ille-et-Vilaine, retenus respectivement pour la richesse de ses paroisses et la qualité du classement de ses archives. Les données réunies, croisées avec les témoignages matériels (orgues, lutrins, stalles, livres de chœur) permettent de tenter une approche globale de l’orgue et de ses usages en Bretagne rurale (commanditaires, facteurs, organistes). Archives et objets permettent également d’aborder la question, largement méconnue en Bretagne, du plain-chant paroissial et de ses conditions d’exercice en milieu rural (lieux, acteurs). À titre d’hypothèse, il semble possible d’avancer que la forte densité du clergé en Bretagne et la faible alphabétisation ont retardé l’émergence de la figure du chantre laïc, qui n’apparaît guère avant la Révolution.
Le manuscrit musical Rés. 1474 de la BNF : un répertoire pour la cathédrale Saint-Pierre de Vannes ou pour les couvents d’alentour ?
Authors: Duron Jean 
Published: June 2024

Le recueil manuscrit Rés. 1474 de la Bibliothèque nationale de France (département de la Musique) est l’un des très rares et précieux témoignages de la musique religieuse en France sous l’Ancien Régime. Ses 430 pages de musique ont été copiées par Claude-Alexis Le Maignan de Kerangat, sous-chantre de la cathédrale de Vannes entre 1708 et 1711. Le recueil rassemble 73 motets dont 50 (les 2/3) sont attribués à Daniel Danielis, maître de musique de la cathédrale de 1684 à 1696 et l’une des figures les plus importantes de la musique religieuse en France sous le règne de Louis XIV. Ce recueil qui semble très homogène, n’est pas sans poser un certain nombre de questions. Certaines touchent les autres compositeurs de ce recueil, pour quelques-uns attachés un temps à la cathédrale. D’autres comme Campra et Brossard, célèbres à Paris dès les années 1695-1700, sont représentés parfois avec des motets inédits qui ont donc pu être chantés à Vannes. Mais la question la plus ardue est certainement celle de la destination de ce répertoire, réservé exclusivement à de petites formations musicales sans rapport avec les effectifs musicaux de la cathédrale.
Regarder Penone
Authors: Cerclet Denis 
Published: June 2024

Nous interrogeons la notion de paysage à partir d’une enquête sur les modes d’observation d’une œuvre de Giuseppe Penone. En nous penchant sur la perception des œuvres d’art au cours de la visite des salles d’un musée, nous nous situons dans l’étude de la perception en action. Alors que la notion de paysage a servi de point de repère pour dire la relation à la nature élaborée en Europe autour de la perspective géométrique, nous avons souhaité la réinterroger en rompant avec le tournant linguistique : nous abordons le paysage sur le plan des mouvements, de l’action et de la sensorialité et dans les pas du tournant corporel. Cela conduit à appréhender le paysage à la façon d’« arrangements hétéroclites » constamment renouvelés par l’expérience. Comme nous avons pu l’observer au cours de l’enquête, faire émerger un paysage est une activité qui mobilise certains savoir-faire.
Sentir le corps de l’intérieur : ethnographie d’une pratique de Zhineng Qigong avec projection d’images

Published: June 2024

Notre ethnographie des méditations avec projection anatomique ou planches de méridiens guidées par l’instructeur interroge la méthodologie d’enquête anthropologique. Nous avons pris le parti d’une ethnographie de participation observante et de faire de ce texte le lieu de l’exercice de notre réflexivité, tout en contextualisant notre propos grâce aux retranscriptions des pratiques que nous avons vécues sur le terrain, les interventions de l’instructeur, Marc Gutekunst, et de certains des participants au stage. L’objectif de cet article est de partager l’essence de notre travail de ces huit dernières années, le temps qu’il nous a fallu pour écrire une thèse de doctorat. En effet, les données exploitées dans cet écrit viennent de nos observations de terrain lors du doctorat, mais sont de première main, car jamais utilisées dans le contenu de la thèse. Nous insistons ici sur la difficulté de témoigner de pratiques « internes », ou de conscience (Midol et Chenault, 2017).

Published: May 2024

Hukum Tata Negara di Indonesia Hukum Tata Negara (HTN) merupakan disiplin ilmu yang mengatur struktur kenegaraan, hubungan antarstruktur organ negara, dan interaksi antara negara dengan warga negara. Jika dilihat ke belakang, HTN di Indonesia memiliki sejarah yang cukup panjang, dari mulai awal kemerdekaan hingga saat ini. Dari waktu ke waktu, HTN tidak selamanya tetap sama dan itu-itu saja tanpa adanya perubahan sama sekali. Tujuan utama dalam penelitian ini adalah memahami bagaimana sejarah HTN atau Ketatanegaraan di Indonesia serta bagaimana interaksi ini mempengaruhi penataan negara. Penelitian ini menggunakan metode kualitatif dengan pendekatan yuridis normatif, mengandalkan studi kepustakaan untuk mengumpulkan data dari buku, jurnal, peraturan perundang-undangan, dan sumber relevan lainnya. Analisis dilakukan dengan mengkaji konsep, teori, dan doktrin hukum yang berkaitan dengan HTN dan sejarahnya di Indonesia. Hasil penelitian menunjukkan bahwa Sejarah HTN/Ketatanegaraan di Indonesia tidak lepas dari konstitusi atau Undang-Undang dasar yang digunakan pada setiap periode. Selain itu, gaya pemerintahan di setiap periode Undang-Undang Dasar yang digunakan pada setiap periode juga tidak sepenuhnya sama satu dengan yang lainnya. Penelitian ini menggarisbawahi pentingnya pendekatan interdisipliner dalam memahami dan mengembangkan HTN untuk menjawab tantangan ketatanegaraan modern.
