Authors: Jasim Israa Nsaif , Khalil Amal Hamza 
Published: January 2025

Current study aims to estimate the impact of physical pretreatment of wheat stalks and corn stalks on biogas production, where two types of pretreatment were used (ultrasonic pretreatment and hydrothermal pretreatment) and three types of animal manure were used as a source of bacteria (cow, sheep and ostrich manure). The results showed a high increment in the amount of biogas generated after pretreatment, as the increase when using ultrasonic pretreatment for wheat stalks inoculated with cow, sheep, and ostrich manure were 31.92%, 20.63%, 155.24%, respectively as compared with untreated samples of wheat stalks. As for the corn stalks, the increase in the biogas when ultrasonic pretreatment for corn stalks inoculated with cow, sheep, and ostrich manure was 57.12%, 43.38%, and 173.05%, respectively, as compared with untreated samples of corn stalks. In hydrothermal pretreatment, the increase in biogas generated by pretreatment for wheat stalks inoculated with cow and sheep manure was 30.57% and 6.10 %, respectively, compared with an untreated sample of wheat stalks. In the hydrothermal pretreatment for corn stalks, the increase was 29.69% and 3.67 %, respectively as compared with untreated sample of corn stalks with the same manure above. An increase was also observed in the amount of methane generated after each of the pre-treated, as the increase in the ultrasonic pretreatment for wheat stalks inoculated cow, sheep, and ostrich manure were 25.25%, 21.96% and 160.78 %, respectively. Whereas, when ultrasonic pretreatment for corn stalks the increase was 88.06%, 54.13%, and 210.91 %, respectively. In hydrothermal pretreatment, the increase in the amount of methane for wheat stalks inoculated with cow and sheep manure was 13.59% and 13.67 %, while, in the corn stalks inoculated with cow and sheep manure was 42.90% and 27.23 %, respectively. Finally, the highest biogas and methane production was obtained when ostrich dung was used as inoculum with wheat and corn stalks pre-treated using ultrasound compared to cow and sheep manure. A substantial accord was seen between the values that were measured and the values that were expected by the modified Gompertz model, as indicated by correlation coefficients that were ≥ 0.96.

Enhanced oil recovery (EOR) is the recovery of oil remaining in a reservoir after primary and secondary recovery methods because it has been exhausted or is no longer economical, using thermal, chemical or mixed gas processes. Most conventional methods are not suitable for extracting oil from high temperature and high pressure (HTHP) reservoirs due to chemical degradation in the environment. Alternatively, electromagnetic (EM) energy is used as a thermal method to reduce oil viscosity in reservoirs, thereby increasing oil production. The application of nanotechnology in EOR is also investigated. In this study, we investigate a non-invasive method by injecting dielectric nanofluids into an oil reservoir simultaneously with electromagnetic irradiation, with the aim of increasing oil production by causing disruption at the oil-water interface. During core displacement tests, ZnO and Al2O3 nanofluids were shown to obtain higher amounts of residual oil than commercial sodium dodecyl sulfate (SDS) surfactant without EM irradiation. With EM irradiation, more residual oil is obtained compared to without irradiation. It has also been shown that changing the viscosity of dielectric nanofluids during electromagnetic irradiation increases sweep efficiency, resulting in higher oil recovery.

The low welfare of teachers is a big task for Islamic Education Institutions, especially Islamic boarding schools, to find solutions to improve their welfare. This research aims to measure the effectiveness of the health insurance and social security programs at the Mambaul Ulum Bata-Bata Pamekasan Islamic boarding school. The program's effectiveness is seen using program evaluation carried out using the CIPP (context, input, process, and product) model developed by Staflebeam. The sources of research data are the person in charge of the program (Madamrosiyah Board of the Mambaul Ulum Bata-Bata Islamic boarding school), school principals, and teachers. The total population is 536 teachers. The sample was taken as 20% of the population, namely 107 people. Primary data was taken using questionnaires and interviews. The questionnaire instrument was tested with construct validity using correlation and Alpha Cronbach. Interviews were conducted with 3 school principals and 6 teachers divided into 3 male and 3 female teachers. Secondary data is obtained by documentation. The research results show that the program has been running effectively and on target. The aside (teachers) have felt the benefits of the program and are satisfied with the existence of this health insurance program because indirectly they worry that if they get sick and have to pay a lot of money can be covered by Islamic boarding school health insurance. The settlement amount is up to 70%. Therefore, this program is recommended for Islamic educational institutions such as Islamic boarding schools to improve their welfare in terms of health insurance. Findings also show that teachers who have received assistance tend to respond positively to the program compared to teachers who have never received assistance.

Dehydration occurs when the body loses too much water and essential fluids in the body. Diarrhea is the main cause of dehydration in toddlers. Toddlers often get diarrhea because their immune system is still vulnerable. If the problem of dehydration is not addressed immediately, it can lead to other health problems such as shock risk. This study aims to determine the effect of video education and demonstration on the ability of first aid dehydration due to diarrhea in mothers with children 0-5 years in Siding Tuban Village. The research design used was Pre Experimental with a one group pretest-postest approach, a sample of 16 respondents taken from 66 populations through Purposive Sampling. Research instrument Ability was measured by observation sheet and analyzed using Wilcoxon Signed Rank test (α=0.05). Before the intervention, 93.8% of respondents had poor skills and after the intervention, 100% of respondents had good skills, which showed an increase in the value of dehydration first aid skills. The results of the analysis obtained p-value=0.000 (<α), meaning that there is an effect of education on the ability of first aid for dehydration due to diarrhea in children. The combination of video and demonstration methods improves the mother's ability to dehydrate children due to diarrhea through visualization and hands-on practice, facilitating understanding and effective application. It is expected that mothers can carry out first aid for dehydration due to diarrhea in children without guidance, reducing the risk of child mortality.

En quête d’image(s)
Authors: SCHWARTZINGER Charlotte 
Published: January 2025

En s’appuyant sur le travail de deux réalisateurs palestiniens – un documentaire de found footage et un essai expérimental – cet article questionne l’importance des archives dans l’élaboration d’une mémoire visuelle palestinienne. De par son histoire cinématographique complexe et son « image manquante/invisibilisée », les créateurs palestiniens emploient aujourd’hui le medium du cinéma pour attester de leur présence. L’auteure entend réfléchir à l’utilisation de l’archive dans la lutte contre l’invisibilité et pour la reconnaissance d’une histoire, d’une culture et d’une mémoire qui sont sans cesse menacées d’effacement. A la lisière entre preuve historique et source d’inspiration esthétique, l’archive fait le lien entre l’image et la mémoire afin d’interroger le présent à l’aide des traces du passé.
De l’historien au citoyen : une nouvelle génération d’artistes libanais à la conquête de la réconciliation d’après-guerre
Authors: PARENTHOU Josephine 
Published: January 2025

Vingt-huit ans après sa fin, la guerre civile libanaise demeure un thème prégnant des œuvres et discours d’artistes beyrouthins là où la société et les institutions en ont fait un tabou. L’art constitue dès lors une entrée privilégiée d’appréhension du contexte social et de ses évolutions dans l’après-guerre. L’effectivité du processus de réconciliation, voire sa monopolisation par les acteurs du monde de l’art, peut être mesurée par des voies non-institutionnelles. Plus encore, la mutation des représentations de guerre dans l’art, entre une génération de guerre et une génération d’après-guerre, reflète une redéfinition de la figure et du rôle de l’artiste dans son rapport au politique : autrefois artiste-historien, l’artiste-citoyen d’aujourd’hui révèle un changement notable dans la conception sociale du Liban, qui repose sur la décommunautarisation urbaine et la désassignation identitaire.

Published: January 2025

Polarisasi politik menjadi salah satu tantangan yang sering hadir dalam penyelenggaraan Pemilu di Indonesia. Polarisasi tidak jarang memicu perselisihan hingga konflik horizontal. Kajian ini akan fokus mengkaji fenomena polarisasi politik di masyarakat Indonesia dalam Pemilu dalam kajian sosiologi hukum. Penelitian ini merupakan penelitian doktrinal dengan menggunakan pendekatan konseptual dan kasus. Bahan-bahan hukum dihimpun melalui studi kepustakaan dan kemudian dianalisis menggunakan teknik deskriptif-analitis. Hasil kajian menyimpulkan bahwa polarisasi politik yang terus berlanjut kan berimplikasi buruk bagi integrasi bangsa, apalagi Indonesia akan menyelenggarakan Pemilu dan Pilkada Serentak 2024. Pada dasarnya dilihat dari penyebabnya, masifnya polarisasi politik sangat relevan dengar teori Arnold Rose dimana faktor seperti teknologi, budaya hingga gerakan sosial sangat mendorong terjadinya polarisasi. Alternatif yang cukup ideal untuk mengurangi polarisasi politik adalah melalui penguatan komunikasi publik yang berlandaskan etika dan dijiwai nilai-nilai kebangsaan Indonesia.

Duck eggs are a source of animal protein which generally have lower foam properties and stability compared to purebred chicken eggs, so that the use of duck eggs is still very less compared to purebred chicken eggs in various processed food products. One form of processed food product from duck eggs is salted duck eggs which are obtained by preserving them using salt (salting). In the preservation process, duck eggs are very susceptible to contamination, so alternatives are needed that can inhibit bacterial growth. Fragrant pandan leaves (Pandanus Ammaryllifolius) are believed to be able to suppress the growth of Escherichia Coli and Staphylococcus aureus bacteria, which are 2 types of bacteria that are an indication of food safety. The aim of this research is to determine the effectiveness of adding fragrant pandan leaf extract (Pandanus Amoryllifolius) on the quality of salted duck eggs produced. The method used in this research was a Completely Randomized Design (CRD) model analysis with the concentration factor of adding fragrant pandan leaf extract (Pandanus amaryllifolius). The method used in this research was a Completely Randomized Design (CRD) model analysis with the concentration factor of adding fragrant pandan leaf extract (Pandanus Amaryllifolius) consisting of 5 treatments, namely A = 0%, B = 3% C = 6%, D = 9 %, E = 12%. Each treatment was carried out 4 times to obtain 20 experimental units. Each treatment was carried out 4 times to obtain 20 experimental units. The results of the research showed that the addition of fragrant pandan leaf juice (Pandanus Amoryllifolius) had a significant effect on the organoleptic test of salted eggs, marked by a decrease in weight loss, ranging from 0,14-13,26 with an average value of 3.09. The total microbacterial test ranged between 0.63x10-7 CFU/mL- 16.16 x 10-7 CFU/mL with an average value of 6.15 x 10-7 CFU/mL, and organoleptic test that the panelists still like.
On the question of the origin of the subethnic group of Russian Arctic old-timers of Yakutia
Authors: Antonov Egor Petrovich 
Published: January 2025

For the first time, the article identifies three stages in historiography on the topic of Russian settlement of the Arctic part of Yakutia: pre-revolutionary, Soviet and post-Soviet. The first of them was dominated by the idea of the resettlement of Russians by the Northern Sea Route from Pomerania to Indigirka. The second stage is characterized by the finds of the remains of a trade and fishing expedition of the XVII century on Taimyr, which proved the existence of ancient traditions of northern navigation. In the third period, evidence of the liquidation of the Russo-Georgian archive appeared, and works on the migration of Russians by the Northern Sea Route began to be evaluated as "local patriotic discourse". For the first time, documents from the United States prove the complex nature of the genesis of Russians in the Arctic occurred by sea and land, as well as assimilation with indigenous peoples. The methodological basis of the study was the civilizational approach, since the genesis of the Russian old-timers of the Arctic was associated with the formation of their ethnocultural characteristics. In the pre-revolutionary period, based on folklore data and the Russo-Georgian archive, the question of Russian migration by sea from Pomerania to Yakutia was first raised. During the Soviet period, the discovery of the remains of a 17th-century commercial and fishing expedition on the Taimyr testified to the existence of ancient shipping traditions in Eastern Siberia. The genesis of historical legends began to be considered as the result of litigation over fishing areas between indigirschiki and Yakuts. The absence of archival documents on the voyages of the Pomors along the Northern Sea Route was noted and it was said about the flight of the ancestors of the indigirschiks from the epidemic from the south to the north. Russian Russian migration route in the post-Soviet period began to be regarded as not an academic, but a local patriotic discourse, the desire to increase their social status, turning them from "not quite Russian" into "the most Russian". The formation of Russian subethnoses occurred due to migration waves by the Northern Sea Route and the Cossack explorers of the XVII century. Indigenous peoples played a decisive role in the emergence of the Russian Arctic old-timers of Yakutia. Also, for the first time, archival documents introduced here in the United States support the conclusions about the centuries-old experience of Pomeranian sailors. The combination of oral traditions, archaeological data and archival materials confirm the guess about the multi-component nature of the origin of the Russian Arctic old-timers of Yakutia.
Single-cell transcriptome analysis reveals cellular reprogramming and changes of immune cell subsets following tetramethylpyrazine treatment in LPS-induced acute lung injury
Authors: Wu Mingyan , Wang Shanmei , Chen Xiaolan , Shen Li , Ding Jurong , Jiang Hongbin 
Published: January 2025

Background
Acute lung injury (ALI) is a disordered pulmonary disease characterized by acute respiratory insufficiency with tachypnea, cyanosis refractory to oxygen and diffuse alveolar infiltrates. Despite increased research into ALI, current clinical treatments lack effectiveness. Tetramethylpyrazine (TMP) has shown potential in ALI treatment, and understanding its effects on the pulmonary microenvironment and its underlying mechanisms is imperative.

Methods
We established a mouse model of lipopolysaccharide (LPS)-induced ALI and performed single cell RNA sequencing (scRNA-seq). Bioinformatic analyses of the immune, epithelial and endothelial cells were then performed to explore the dynamic changes of the lung tissue microenvironment. We also analyzed the effects of TMP on the cell subtypes, differential gene expression and potential regulation of transcriptional factors involved. Immunohistochemistry and enzyme-linked immunosorbent assay were performed to identify the effects of TMP on immune inflammatory response.

Results
We found that TMP efficiently protected against LPS-induced acute lung injury. Results of scRNA-seq showed that the cells were divided into seven major cell clusters, including immune cells, fibroblasts, endothelial cells and epithelial cells. Neither dexamethasone (Dex) nor TMP treatment showed any significant protective effects in these clusters. However, TMP treatment in the LPS-induced ALI model significantly increased follicular helper T cells and reduced CD8+ naive T cells, Vcan-positive monocytes and Siva-positive NK cells. In addition, TMP treatment increased the number of basal epithelial cells and lymphatic endothelial cells (LECs), indicating its protective effects on these cell types. Scenic analysis suggested that TMP likely mitigates LPS-induced injury in epithelial and endothelial cells by promoting FOSL1 in basal epithelial cells and JunB in LECs.

Conclusions
Our findings suggest that TMP appears to alleviate LPS-induced lung injury by regulating the immune response, promoting epithelial cell survival and boosting the antioxidant potential of endothelial cells. This study highlights the potential therapeutic use of TMP in the management of ALI.
