Published: January 2023

IntroductionTotal anomalous pulmonary venous connection (TAPVC) is a rare but critical cardiac anomaly, in which pulmonary veins are connected to an abnormal location rather than the left atrium. The prognosis can be extremely poor without intervention, with a mortality of 80% during infancy. The purpose of this research is to summarize the outcomes and relevant risk factors of 80 total anomalous pulmonary venous connection (TAPVC) patients who underwent primary TAPVC sutureless repair and discuss the indications and benefits of primary sutureless repair.MethodsThis retrospective review included 80 patients with TAPVC who underwent primary sutureless repair at a single institution between January 2015 and December 2020. Patients were subdivided into 4 groups according to Darling's classification. Risk factors that increase the postoperative pulmonary vein flow velocity were explored by Multiple Linear regression.ResultsAnatomic TAPVC subtypes included supracardiac 35 (43.8%), cardiac 24 (30%), infracardiac 17 (21.2%), and mixed 4 (5%). Median age at repair was 16.5 days and median weight was 3.5 kg. Preoperative pulmonary venous obstruction (PVO)was presented in 20 (25%) patients. There were 2 early deaths and 1 late death. 2 patients developed postoperative PVO and none required reintervention. Prolonged cardiopulmonary bypass time (CPB) (p = 0.009), preoperative pneumonia (p = 0.022) and gender (p = 0.041) were found to be associated with the increase of postoperative pulmonary vein flow velocity.DiscussionUnder the primary sutureless technique, no statistical difference was observed among the 4 subgroups in terms of postoperative pulmonary vein flow velocity (p = 0.589). The primary sutureless technique may eliminate the differences between subtypes while decrease the postoperative PVO rate, which makes it applicable in any subtypes of TAPVC. Following the favorable outcomes in preventing postoperative PVO in all subtypes in this study, we advocate the indications for primary sutureless repair may expand further to all the TAPVC patients.

Bridging the gap between laboratory-scale experiments and actual oilfield operations is a complex task that requires a compromise between real (authentic) fluids and model systems. Commercial products (i.e., asphaltene inhibitors and dispersants) are often designed to target a wide range of operating conditions and compositions of crude oils, which means that the performance becomes almost case-specific. Through Atomic Force Microscopy (AFM) imaging and Transmission/Backscattering signals (T/BS), the morphology of asphaltene deposits and the mechanisms that eventually lead to precipitated material were evaluated. Two different models (starting solutions) with four different n-alkanes were used to induce variability in asphaltene agglomeration and subsequent precipitation paths. It was found that increasing the carbon number shifted the observed precipitation detection time (T/BS data suggested a shift in the order of ~1000 s when comparing low and high carbon numbers) and influences the density of the precipitated material under static and a sufficiently high concentration of solvent conditions. Further analysis on the morphology of the resulting material after the addition of commonly used chemicals showed that asphaltene stability through inhibition (i.e., blockage or crowding of potential active sites) led to smaller complexes. One of the additives (PIBSA) reduced the average height in ~33% and the mean square roughness in ~72%. On the other hand, stability through dispersion (i.e., hindering agglomeration) leads to a polymer-like network bigger in size, noting that in both cases the system remains soluble. The use of APR resulted in an increase of ~41% and ~54% for the same parameters. This insight sheds light on how to devise efficient chemical strategies to prevent flow assurance issues.

Carnivorous plants adsorb prey-derived nutrients partly by endocytosis. This study quantifies endocytosis in Drosophyllum lusitanicum, Drosera capensis, Drosera roseana, Dionaea muscipula and Nepenthes × ventrata. Traps were exposed to 1% fluorescent-labeled albumin (FITC-BSA), and uptake was quantified repeatedly for 64 h. Formation of vesicles started after ≤1 h in adhesive traps, but only after 16 h in species with temporary stomach (D. muscipula and N. × ventrata). In general, there are similarities in the observed species, especially in the beginning stages of endocytosis. Nonetheless, further intracellular processing of endocytotic vesicles seems to be widely different between species. Endocytotic vesicle size increased significantly over time in all species except in D. capensis. Fluorescence intensity of the endocytotic vesicles increased in all species except D. muscipula. After 64 h, estimates for FITC-BSA absorption per gland ranged from 5.9 ± 6.3 ng in D. roseana to 47.8 ± 44.3 ng in N. × ventrata, demonstrating that endocytosis substantially contributes to the adsorption of prey-derived nutrients.

Authors: Abidin Achmad Anwar 
Published: January 2023

This research fills the gap in studies of communication models towards children because, from the existing studies, there is still a space that requires a more profound discussion regarding communication patterns that emphasize the values and spirit of Islamic education from the perspective of the Qur'an. The novelty of the researcher's writing. This research is qualitative. Qualitative research is research that produces descriptive data. The type of qualitative research used in this research is library research. Islamic education for children carried out by parents and teachers in formal, non-formal, and informal education must be equipped with good communication skills. Of course, communication under the Qur'an demanded reliability and promoting dialogue. Parents and teachers must be able to communicate teaching material so that it can be implemented by the child, which in the end, has a positive impact on the child. In everyday life, parents and teachers must be able to communicate well with children because communication is essential. Moreover, in communicating with children according to the guidance of the Qur'an, parents, and teachers should be able to communicate with children with qâulan balighâ, qâulan layyina, qâulan ma'rufa, qâulan maysura, qulan karima and be able to give willingness, advice, preaching and taushiyah so that children become a more polite and moral person like the way of communicating the prophet Ibrahim to the prophet Ismail AS.

Abstrak: Upaya penyelamatan cagar budaya merupakan hal yang wajib dilakukan karena merupakan identitas sebuah bangsa. Melalui penelitian ini akan dijelaskan bagaimana lapangan merdeka Lubuklinggau ini dapat menjadi dasar untuk dijadikan situs budaya lahan bersejarah. Adapun tujuan penelitian yaitu menjelaskan Lapangan Merdeka Lubuklinggau sebagai situs budaya lahan bersejarah (1934-1988). Metode penelitian yang digunakan ialah metode sejarah, dengan tahapan: heuristik, kritik sumber, interpretasi, dan historiografi. Hasil penelitian menunjukan bahwa bangunan atau situs umumnya kurang mendapat perhatian. Bangunan-bangunan bersejarah yang penting umumnya berada di pusat-pusat kota. Kini pusat kota dikembangkan menjadi daerah komersial sehingga cagar budaya yang ada di wilayah ini sangat rentan untuk dibongkar dan digantikan dengan bangunan-bangunan pusat belanja atau wisata, seperti misalnya Lapangan Merdeka yang berada di Kota Lubuklinggau, Provinsi Sumatera Selatan. Oleh karenanya, tempat ini merupakan lokasi peristiwa lintas zaman dimulai dari masa kolonial, masa revolusi fisik dan masa orde baru.Kata Kunci: Lapangan, Merdeka, Situs, Budaya, Lahan, Bersejarah.Lubuklinggau Merdeka Field As A Cultural Site Historical Land 1934 - 1988 Abstract: Efforts to save cultural heritage is something that must be done because it is the identity of a nation. Through this research, it will be explained how the Lubuklinggau independent field can be the basis for becoming a historical land cultural site. The purpose of the research is to explain the Lubuklinggau Merdeka Square as a historical land cultural site (1934-1988). The research method used is the historical method, with stages: heuristics, source criticism, interpretation, and historiography. The results showed that buildings or sites generally received less attention. Important historical buildings are generally located in city centers. Now the city center has been developed into a commercial area so that the cultural heritage in this area is very vulnerable to be demolished and replaced with shopping or tourist center buildings, such as Merdeka Square in Lubuklinggau City, South Sumatra Province. Therefore, this place is the location of events across the ages starting from the colonial period, the physical revolution period and the new order era.

Published: January 2023

TOEFL is one method of measuring English competence and serving as a standard for anyone studying or speaking English as a foreign language. Because the TOEFL is a globally renowned language test that certifies one's English ability, there is a minimum score to achieve in order to complete a certain requirement, such as a support document to apply for a job, institution, or study abroad. It is challenging for almost all Indonesians to attain a minimum TOEFL score. The purpose of this article was to figure out the effectiveness of the TOEFL preparation training program in enhancing students' TOEFL score. This paper gathered information using action research, which consists of four steps: planning, implementation, observation, and reflection. The TOEFL training program was carried out four times a week for a month, including eight meetings for listening comprehension, ten meetings for structure and written expression, and ten meetings for reading comprehension. The class divided into three classes for each class consisting of 32 students. From the result, it can be seen that there is a significant improvement after the students participated in the TOEFL training program. It showed the students who reach score ≤400 in post-test more than in pre-test and the score increased as expected. On the pre-test, the students who got scores 400-500 was only 3% and after the training was given it increased became 13%. It can be concluded that TOEFL training program not only helps the students to improve their scores but also their comprehension of the TOEFL test

ABSTRACT
Broccoli is known to be very rich in secondary metabolites, such as alkaloids, flavonoids, tannins, polyphenols, essential oils, and polypeptides. Alkaloids are one of the secondary metabolites that are commonly found in nature and have physiological activities. The extraction time factor is the thing that can affect the quality of the extraction results which in this study is the alkaloid content. This study aims to determine the optimal maceration time so that it can produce optimum total alkaloid content. The stages in this study include sample preparation and then sample extraction by maceration using 96% ethanol with differences in maceration time of 1 day, 2 days and 3 days. Furthermore, identification using TLC and analysis of total alkaloid content using UV-Vis spectrophotometer. Kruskal Wallis test was used to determine whether there was an effect of maceration time on total alkaloid content. The results showed that the highest average total alkaloid content in the second sample was maceration for 2 days with a concentration of 17.5%. The Kruskal Wallis test showed that there was no effect between maceration time on total alkaloid content.
