Annually, confectionary sunflower varieties occupy from 300 to 500 thousand hectares in the Russian Federation. The varieties developed last years (Karavan, Konditer, SPK Plus) are able to form high yields of seeds in the heavy agroclimatic conditions. At the same time, spreading of the new more virulent races of broomrape causes the significant decrease in yield of confectionary varieties. One of the effective methods of broomrape control is chemical one. The experiment was conducted on isolated plot in field after introducing the seeds of the virulent broomrape races in soil. Treatment with herbicides in recommended doses was conducted using backpack sprayer. The level of broomrape control with imidazolinons is significant and equitable to action of a gen of broomrape resistance Or7 by both percentage and a level of infection. Tribenuron-methyl repressed a level of infection under high infestation with broomrape in the studied confectionary sunflower varieties.

Objetivo: Avaliar os benefícios de proteção renal e cardiovascular pelo uso de Inibidores de SGLT-2. Revisão bibliográfica: A Dapaglifozina e outros medicamentos dessa classe são responsáveis por inibir o cotransportador sódio-glicose 2 e isso faz com que ocorra redução da glicemia sanguínea, aumento da função secretora das células β – pancreáticas e aumento da natriurese. Nesse contexto, um conjunto de estudos apontou para diminuição do risco de desenvolvimento de insuficiência renal (IR), insuficiência cardíaca (IC), bem como o aumento da sobrevida desses pacientes e portadores de DM2 que podem apresentar ou não complicações relacionadas a esses sistemas. Considerações finais: Os inibidores de SGLT-2 apresentaram evidências de mecanismos relacionados a renoproteção como a indução da glicosúria, aumento da transição linear entre reabsorção e excreção renal de glicose e cardioprotetores como diminuição da pré e pós-carga, melhoria na função diastólica e, portanto, cabe analisar seus possíveis efeitos colaterais para que os riscos e benefícios amparem sua utilização em pacientes renais e/ou cardíacos.
Dissolution-limited reactions in solid-state synthesis
Authors: Yamamoto Tetsuya , Kubota Koji , Ito Hajime
Published: May 2023

A mechanochemical approach using ball milling enables us to carry out organic reactions between solid-state reactants as well as those between liquid reactants. Under such mechanochemical conditions, a considerable reactivity difference between liquid and solid reactants is often observed, which may result from the poor-diffusivity of reactants in solids. The chemical reaction between reacting solids happens at their interface and forms a region rich in products. We here integrate the Landau theory of the solid-liquid phase transition into the Onsager’s theory of irreversible processes to theoretically predict the reaction kinetics limited by the diffusion of reactants through the heterogeneous interfacial region. Our theory predicts that in the limit of low temperature, the reaction kinetics is mostly limited by the dissolution of reactant molecules into the product-rich phase, rather than the poor diffusivity in solids, and provides a quantitative relationship between the reaction rate and the equilibrium miscibility phase diagram.
Isolation of Hydroxyapatite from Atlantic Salmon Processing Waste Using an Enzyme Cocktail

Published: May 2023

There is a need to solve ongoing waste management issues in food processing industries. The demand for fish, including salmon, is higher than ever because of the growing global population and protein needs, however this results in large quantities of wasted by-products. This waste is problematic because it is potentially harmful to the environment and results in significant disposal costs for industries. The salmon frame (bones) is disposed of during processing but is a potential feedstock for hydroxyapatite, a mineral for value-added applications. While previous research has accessed hydroxyapatite from animal wastes, these processes either use very high temperatures or chemicals that are more costly and hazardous than the method described herein. In this study, we developed an enzymatic treatment using proteases and lipases simultaneously to clean the residual meat from salmon frames to isolate collagen-containing hydroxyapatite (sHAP) using Design of Experiment (DoE) under benign conditions. The variables were optimized using 2x3 and 2x4 factorial designs and it was determined by characterization techniques, weight loss calculations, and thermogravimetric analysis that the meat from the salmon frame was successfully hydrolyzed with 15 μL/g Neutrase and 7.5 μL/g Lipozyme CALB L in 40 °C tap water for 6 h. We have performed a life cycle analysis to compare the current method with previously reported processes used to treat other types of fishery waste. The method reported herein is less impactful (environment, hazard, cost, carbon footprint) than others in the literature, as there are no solvents required, enzymes are easily disposed, and temperatures do not exceed 100 °C during the entire process. Furthermore, the optimized conditions were then used on a larger scale and up 15 salmon frames were easily processed at one time.

Published: May 2023

We recently synthesized prospective new materials composed of alternating quasi-atomic sheets of brucite-type hydroxide (Mg,Fe)(OH)2 and CuFe1-xS2 sulfide (valleriites). Herein, their thermal behavior important for many potential applications has been studied in inert (Ar) and oxidative (20% O2) atmosphere using TG and DSC analysis and characterization with XRD, XPS, SEM and EDX. In Ar media, the processes are determined by dehydroxylation of the hydroxide layers forming MgO, with the temperature of the major endothermic maximum of the mass loss at 413 °C. Sulfide sheets start to degrade below 500 °C and melt nearby 800 °C, with bornite, chalcopyrite and troilite specified as the final products. In oxidative atmosphere, the exothermic reactions with the mass increase peaked at 345 and 495 °C correspond to a partial and major oxidation of Cu-Fe sulfide layers, respectively. Sulfur oxides captured in magnesium hydroxide layers to form MgSO4 compromised the layer integrity and promoted oxidation of the sulfide entities. The final products contained also minor MgO, Cu2MgO3, Fe3O4 and MgFe2O4 phases. Samples doped with Al, which decreases the content of Fe in hydroxide layers, show notably impeded decay of valleriite in argon but facilitated oxidation of Cu-Fe sulfides, while the impact of Li (it slightly increases the number of the Fe-OH sites) was less expressed. The mutual stabilization of the 2D hydroxide and sulfide layers upon heating in inert atmosphere but not in oxygen as compared with bulk brucite and chalcopyrite was suggested to explain by high thermal resistance across the stacked incommensurate sheets, which slows down the endothermic reactions and accelerates the exothermic oxidation; the high number of Fe atoms in the hydroxide sheets are expected to promote the phonon exchange and heat transfer between the layers.

Published: May 2023

Cu-O$_2$ structures play important roles in bioinorganic chemistry and enzyme catalysis, where the bonding between Cu and O$_2$ parts serves as a fundamental research concern. Here we performed a multiconfigurational study on the copper L$_{2,3}$-edge X-ray absorption spectra (XAS) of two copper enzyme model complexes to gain a better understanding of the antibonding nature from clearly interpreted structure-spectroscopy relation. We obtained spectra in good agreement with the experiments by using the restricted active-space second-order perturbation theory (RASPT2) method, which facilitated reliable chemical analysis. Spectral feature interpretations were supported by computing the spin-orbit natural transition orbitals. All major features were assigned to be mainly from Cu $2p$ to antibonding orbitals between Cu $3d$ and O$_2$ $\pi^{*}$, Cu$3d-\pi^*_\text{O-O}$ (Type A), and a few also to mixed antibonding/bonding orbitals between Cu $3d$ and O$_2$ $\pi$, Cu$3d\pm\pi_\text{O-O}$ (Type M). Our calculations provided a clear illustration of the interactions between Cu $3d$ and O$_2$ $\pi^{*}$/$\pi$ orbitals that are carried in the metal L-edge XAS.

Published: May 2023

Nickel-catalyzed efficient asymmetric synthesis of chiral chromans with quaternary allylic siloxanes and their antitumor activity is reported for the first time. A P-chiral monophosphine ligand (R)-AntPhos was found to be the ideal ligand to form a series of tertiary allylic siloxanes bearing chroman structures with excellent yields, enantioselectivities and E/Z selectivity using triethylsilane as the reductant. This reaction has a broad substrate scope and provides a practical way to synthesize useful chroman derivatives with chiral tertiary allylic alcohols. Up to 69 examples were successfully established with this method. A series of 3-hydroxychroman derivatives were obtained and tested for anti-tumor activity. Number of compounds showed good anti-tumor activity, less toxicity to reference cell, and specificity to different cancer cells, which could be new anticancer leading compounds. The configuration and substituent of the 3-hydroxychromans has big effects for their anti-tumor activity. Further study on structure-activity relationships of these 3-hydroxychromans is under investigation to discover new anti-cancer drugs.
Estimating Free Energy Barriers for Heterogeneous Catalytic Reactions with Machine Learning Potentials and Umbrella Integration

Published: May 2023

Predicting the rate constants of elementary reaction steps is key for the computational modelling of catalytic processes. Within transition state theory (TST), this requires an accurate estimation of the corresponding free energy barriers. While sophisticated methods for estimating free energy differences exist, these typically require extensive (biased) molecular dynamics simulations that are computationally prohibitive with the first-principles electronic structure methods that are typically used in catalysis research. In this contribution, we show that machine-learning (ML) interatomic potentials can be trained in an automated iterative workflow to perform such free energy calculations at a much reduced computational cost as compared to a direct density-functional theory (DFT) based evaluation. For the decomposition of CHO on Rh(111), we find that thermal effects are substantial and lead to a decrease in the free energy barrier, which can be vanishingly small depending on the DFT functional used. This is in stark contrast to previously reported estimates based on a harmonic TST approximation, which predicted an increase of the barrier at elevated temperatures. Since CHO is the educt of the putative rate limiting reaction step in syngas conversion on Rh(111) and essential for the selectivity towards $\mathrm{C}_\mathrm{2+}$ oxygenates, our results call into question the reported mechanism established by microkinetic models.
New measurements reveal a large contribution of nitrogenous molecules to ambient organic aerosol

Published: May 2023

Nitrogen is a significant element that constitutes ambient organic aerosol. Individual N-containing organic molecules are known to have both natural and anthropogenic sources and implicated in a wide-ranging health and environmental effects. Yet, unlike carbon (C), the total quantity of aerosol organic nitrogen (ON) remains largely unquantified, hindering a quantitative understanding of their major sources and impacts. Here, for the first time, aerosol ON is quantified in hundreds of aerosol filter samples collected from sites of varying urban influence in China using our recently developed method that permits simple, and yet sensitive, simultaneous detection of inorganic and organic nitrogen. Annual average ON concentration was in the range of 0.4-1.4 μg N m-3, representing 17-31% of aerosol total nitrogen. Monte Carlo simulations constrained by paired ON and organic carbon (OC) measurements suggest N-containing organic molecules contributed typically 37-50%, with a 95% confidence interval of [12%, 94%], to ambient organic aerosols. Source apportionment analysis reveals that biomass burning and secondary formation are dominant ON sources, accounting for 21-24% and ~30% of ON, respectively. Primary biological aerosol is also a significant source of ON (7-18%), with its contribution more prominent in non-urban atmospheres. The revelation of the large presence of nitrogenous molecules in atmospheric aerosols implies their role in carbon chemistry has likely been under-appreciated in the past. This new compositional insight, we anticipate, would bring forth a breakthrough in our ability to describe and model organic aerosols and to rethink the focus of studying and modeling OA.

Published: May 2023

Herein we report the antimicrobial activity of the self-assembled structures formed by protected single amino acids (SAAs) and also their application as a tool for overcoming antibiotic resistance. Interestingly, SAAs modified with simple protecting groups like -Fmoc, -Boc, -Cbz exhibit antibacterial activity and is useful in overcoming the antibiotic resistance in wide spectrum of bacterial strains namely Escherichia coli, Staphylococcus aureus, Bacillus subtilis, P. aeruginosa, Vibrio cholera and Enterococcus faecalis as in there presence the concentration of antibiotic required to inhibit bacterial strain was decreased manifold . The SAAs themselves exhibited antimicrobial activity albeit higher doses of the SAAs as compared to chloramphenicol alone was required for inhibition. However, in presence of antibiotics the concentration required for SAAs as well as antibiotic was lowered manifold particularly in case of S. Aureus, P. aeruginosa and E. Faecalis the IC50 value of peptides alone was even less than chloramphenicol. When peptides were used in combination with chloramphenicol antibiotic resistance was overcome in wide spectrum of bacterial strains and the concentration of chloramphenicol required was drastically reduced.
Más allá de las Naciones. Revoluciones, contrarrevoluciones e independencias (1795-1830)
Authors: Martínez-Flener Milagros
Published: May 2023

Juan Marchena señaló en su momento, que “hay que dejar de seguir mirándonos el ombligo”. Esta frase, pensada para el contexto de las independencias americanas, refleja su profunda preocupación a favor de una historia que rompiera los esquemas locales, las fronteras nacionales y se interconectara con una más amplia que permitiese analizar los devenires de América, enlazando acontecimientos tanto americanos como europeos. Más allá de las Naciones pretende romper con la aceptación general de que todos los movimientos políticos y sociales que tuvieron lugar durante el primer cuarto del siglo XIX fueron nacionales y tuvieron como fin último la independencia. Si bien los trabajos aquí presentados se inscriben en el contexto de las revoluciones liberales que dominaron en Europa y se expandieron a Ultramar, y en el de las guerras de independencia americanas, ellos investigan y analizan movimientos, revueltas, procesos y actores que, ante todo, lucharon para lograr sus propios fines, su propia libertad, así como el reconocimiento, la igualdad, y la aceptación de la sociedad en la que vivían.
Improving inflation forecasts using robust measures
Authors: Verbrugge Randal J. , Zaman Saeed
Published: May 2023

Theory and extant empirical evidence suggest that the cross-sectional asymmetry across disaggregated price indexes might be useful in forecasting aggregate inflation. Trimmed-mean inflation estimators have been shown to be useful devices for forecasting headline PCE inflation. But is this because they signal the underlying trend or because they implicitly signal asymmetry in the underlying distribution? We address this question by augmenting a "hard" to beat benchmark headline PCE inflation forecasting model with robust trimmed-mean inflation measures and robust measures of the cross-sectional skewness, both computed using the 180+ components of the PCE price index. Our results indicate significant gains in the point and density accuracy of PCE inflation forecasts over medium- and longer-term horizons, up through and including the COVID-19 pandemic. Improvements in accuracy stem mainly from the trend information implicit in trimmed-mean estimators, but skewness information is also useful. An examination of goods and services PCE inflation provides similar inference.

Objective: To investigate the effect of combined detection of serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), cancer antigen 125 (CA125), and neuron-specific enolase (NSE) in patients with lung cancer by fluorescence flow cytometry. Methods: From August 2019 to July 2022, 200 patients with lung cancer diagnosed by pathology in our hospital were retrospectively analyzed. 2 mL venous blood was collected in a fasting state and centrifuged to separate the serum (containing human chorionic gonadotropin antibody [anti-hCG antibody], hepatitis B surface antibody [anti-HBs antibody], and CEA). Results: The sensitivities of CEA and CYFRA21-1 detected via enzyme-linked immunosorbent assay (ELISA) were 100%, and the detection limits were 0.5 ng/mL and 0.1 ng/mL, respectively; the sensitivities of CA125 and NSE detected via flow cytometry were 100%, and the detection limits were 10 U/mL and 2 ng/mL, respectively. Compared with ELISA, the sensitivities of CA125 and NSE detected via flow cytometry were higher. When the concentration of CEA was 10–40 ng/mL, the sensitivities of the three markers CYFRA21-1, CA125, and NSE showed no significant changes (P > 0.05); when the concentration of CEA was 40–80 ng/mL, the sensitivity of CEA significantly decreased (P < 0.01), but the sensitivities of the three markers CYFRA21-1, CA125, and NSE showed no significant changes (P > 0.05); when the concentration of CEA was 80–200 ng/mL, the sensitivities of all four markers showed no significant changes (P > 0.05). Conclusion: Compared with the double-antibody sandwich ELISA, fluorescence flow cytometry has certain advantages, including high sensitivity, good precision, short detection time, low sample usage, and low medical cost; thus, it is worthy of clinical promotion.

Background: The transition to telehealth services for mothers of preterm babies is a challenge in promoting the health of preterm infants, although telehealth allows real-time interaction and support for mothers. Aim: To compare the experiences of mothers of hospitalized and discharged preterm infants with telehealth services in the Islamic Republic of Iran. Methods: This qualitative study was conducted from June to October 2021 using a conventional content analysis approach. The study participants included 35 hospitalized and 35 discharged mothers of preterm infants, who received healthcare consultations through WhatsApp and Telegram applications. They were selected using purposive sampling. Data collection was done using in-depth semi-structured interviews and data analysis was performed using Graneheim and Lundman analysis. Results: Our findings showed request for continuing healthcare support by the mothers as the main category, with 3 subcategories: willingness to connect to telehealth services, more comprehensive education about telehealth services, and opportunities to share experiences. Mothers of hospitalized and discharged preterm infants had conflicting views about the ambiguous role of nurses in telehealth and the use of telehealth as a support system. Conclusion: Telehealth plays an important role as a supportive method in promoting infant health and boosting the confidence of mothers of preterm infants as they continuously interact with nurses.

Published: May 2023

Background: Low breastfeeding rates are a global concern, and few studies have examined breastfeeding in Oman. Aims: We examined the associations of mothers’ sociodemographic characteristics, breastfeeding knowledge, attitudes, subjective norms, perceived control, previous breastfeeding experience, and early breastfeeding support with infant feeding intention at birth and breastfeeding intensity at 8 weeks postpartum. Methods: We used a descriptive, prospective cohort design. Data collection was in 2016. We administered a structured questionnaire to mothers at postpartum discharge from 2 hospitals in Oman and followed up once via a 24-hour dietary recall at 8 weeks. We used a path analysis model (n = 427) using SPSS, version 24.0, and Amos, version 22. Results: During the postpartum hospitalization, 33.3% of mothers reported that their babies received formula milk. At the 8-week follow-up, 27.3% of mothers were exclusively breastfeeding. Subjective norms (measured by social and professional support) were the strongest predictors. Infant feeding intention significantly predicted breastfeeding intensity. Returning to work/school was the only sociodemographic variable to significantly correlate with breastfeeding intensity (r = –0.17; P < 0.001); mothers who planned to return to work/school had significantly lower intensity. Knowledge significantly predicted positive and negative attitudes, subjective norms and perceived control. Early breastfeeding support negatively correlated with breastfeeding intensity (r= –0.15; P < 0.001). Conclusion: Infant feeding intention positively predicted breastfeeding intensity with subjective norms or social and professional support and had the strongest correlation with mothers’ intentions.

Published: May 2023

Introduction: Several studies have investigated COVID-19 vaccine acceptability and hesitancy, especially among healthcare workers (HCWs). However, acceptability of the vaccine by HCWs in Sudan remains unclear. Aims: We investigated acceptability of the COVID-19 vaccine and its determinants among HCWs in Sudan. Methods: Using a semi-structured questionnaire, we conducted a web-based cross-sectional study of COVID-19 vaccine hesitancy and its associated determinants among healthcare workers in Sudan during March–April 2021. Results: A total of 576 HCWs responded to the survey. Mean age was 35 years. Females (53.3%), medical doctors (55.4%) and being located in Khartoum State (76.0%) each accounted for more than half of the participants. Absolute refusal of the COVID-19 vaccine was expressed by 16.0% of the respondents. Males were more than twice as likely to accept the vaccine as females. Lower acceptability was statistically significantly associated with the nurses (OR = 0.35, 95% CI: 0.15–0.82, P < 0.001), increased perceived harm from the vaccine (OR = 0.11, 95% CI: 0.05–0.23, P < 0.001), lack of confidence in the source of the vaccine (OR = 0.16, 95% CI: 0.08–0.31, P < 0.001) and lack of confidence in organizations or government sectors supervising the vaccination process (OR = 0.31, 95% CI: 0.17–0.58, P < 0.001). Conclusion: This study highlights a moderate level of COVID-19 vaccine acceptability among HCWs in Sudan. Special consideration should be given to addressing vaccine hesitancy among female HCWs and nurses.

El estado contemporáneo de la imagen digital y global conduce desde el interrogante inaugural de los estudios visuales por la naturaleza de las imágenes hacia la pregunta por las condiciones materiales de su omnipresencia actual. En este trabajo señalamos dos procesos centrales de la imagen contemporánea que permiten pensar su devenir total: la digitalización y la ubicuidad. Contra un sentido común que nos llevaría a ver en lo digital nada más que inmaterialidad, subrayamos tres claves materiales en la digitalización: lo fantasmal como modo de circulación; las pantallas como soporte tecnológico; el substrato mineral de los dispositivos. En la segunda parte, contra la idea de que la ubicuidad es nada más que multiplicación de imágenes, proponemos: volver a pensar la profusión en términos políticos como ocularcentrismo; en términos económicos como superabundancia (central para el desarrollo del neoliberalismo); y en términos psicosociales como cibervigilancia.

Published: May 2023

Graduate students commonly experience apprehension towards statistics courses, leading to lower achievement and negative perceptions of the subject. This mixed-methods research study aimed to explore the effects of blended learning on graduate students' achievement and perception of statistics in the Master of Arts in Education program. Blended learning combines online and face-to-face learning modalities. The study included 67 participants who completed tests for parametric and non-parametric statistics and 12 who underwent interviews. Results showed that students showed mastery of specific statistical topics, particularly correlation and regression tests and tests of difference with paired and independent samples. The students attributed their success to blended learning, which promotes flexibility, ease of learning statistics, independent learning, and motivation. Regardless of the field of specialization, students' scores in statistics were similar. However, challenges such as internet connection, software use, and technicalities of concepts and software like SPSS were reported. This study suggests that blended learning is beneficial for improving graduate students' achievement and perception of statistics and that proper support and guidance are needed to address the challenges of this learning modality.

دور المساعدة القانونية في إرساء مبدأ العدالة الاجتماعية - دراسة مقارنة في ضوء الأنظمة القانونية المقارنة
Authors: هلال محمد حسين محمد
Published: May 2023

يستحق مفهوم المساعدة القانونية، أن يكون حاضرًا على أجندة المشرعين في العصر الحالي؛ لما يمثله من تعزيز لتحقيق العدالة الاجتماعية، خاصةً للفئات الهشّة والضعيفة، في ظل ارتفاع أتعاب المحاماة، وبالتالي يتهدد حقهم في الوصول إلى العدالة القضائية. وإذا كانت المساعدة القانونية، تعد أحد أهم الوسائل المثلى للوصول إلى العدالة، فإنها تعد تجسيدًا أساسيًا لمبدأين كبيرين في الحياة الدستورية، وهما؛ سيادة القانون، ومبدأ المساواة وعدم التمييز، وهذان المبدآن بدورهما يشكلان عماد دولة القانون، وهو الهدف الرئيس الذي تصبوا إليه كل الدول، وتتطلع إليه كافة المجتمعات. وقد توصلنا في بحثنا إلى الربط بين المساعدة القانونية، والعدالة الاجتماعية؛ حيث إننا نرى نظريًا، الإجماع القانوني على أهمية إرساء العدالة الاجتماعية، غير أننا واقعيًا نبدو أمام فجوة متمثلة في غياب المفهوم عن الطبقات الفقيرة، والضعيفة.
المساعدة القانونية في إطار القانون المدني: المفهوم والمعايير - دراسة تحليلية مقارنة
Authors: داود إبراهيم عبد العزيز
Published: May 2023

برغم ما يعكسه مسمى مفهوم المساعدة القانونية من معانٍ تتسم بطابع الحماية، إلا أن تجسيده واقعيًا من خلال نصوص القانون المدني يُظهر العديد من القيود التي تؤثر سلبًا على حقوق الفئات الضعيفة، الأمر الذي يستوجب إعادة النظر فيه في ضوء تطورات الواقع. تكمن إشكالية البحث في قصور التنظيم القانوني للمساعدة القانونية لذوي الإعاقة في القانون المدني؛ الأمر الذي أدى إلى غموض المفهوم، وإلى ندرة في الدراسات الفقهية أو التطبيقات القضائية التي يجب أن تسهم في تفعيل الدور الحمائي لهذا المفهوم. يقتضي تناول هذا الموضوع دراسةً تحليلية لمفهوم المساعدة القانونية، وكيفية تجسيده واقعيًا في القانونين المصري والقطري؛ للوقوف على نقاط الضعف والجمود التي تستوجب التفعيل من خلال آليات قانونية محددة، يمكن استلهامها من القانون الفرنسي، بما لا يخل بالثوابت القانونية التي تجد أساسها في الشريعة الإسلامية. ولا شك في أن تلك المعالجة الجديدة لمفهوم المساعدة القانونية تثري مضمونه، وتمد نطاق تطبيقه إلى فئات أخرى من الأشخاص المحرومين من ممارسة حقوقهم المدنية؛ كالمجنون والمعتوه. هذه التطبيقات الجديدة التي تجسد المفهوم واقعيًا تعدّ من الأوجه المستترة لمفهوم المساعدة القانونية التي يكشف البحث عنها النقاب، ويمهد من خلالها لدراسات مستقبلية متعمقة في موضوع لم تسبر أغواره في القانونين المصري والقطري.

This marriage is considered the ideal type of marriage in Minangkabau. The data sources were obtained from the result of interview with married couples, traditional leaders, and religious leaders. The collected data were then reduced, presented, and concluded.

This tradition can build family resilience in the terms of economic and social, and it strengthens cultural resilience as well. From the perspective of maqashid al-sharia, Pulang ka Bako marriage does not only bring benefit to the individual but also to the family. Besides fulfilling the elements of hifzun nasl (preserving offspring), hifzul mal (managing assets), and hifzul 'irdh (maintaining honor), Pulang ka Bako also fulfills the elements of tahqiqul sakn wal mawaddah wa rahmah (realizing the sense of peace, love, and compassion) and tanzimul janibul mali (managing family finances). It can be concluded that Pulang ka Bako type of marriage has fulfilled the objectives of Islamic law and is capable of being one of the solutions to family resilience issues.
