The Concept of "Humanity" in the Perspective of Maqāṣid Al-Sharī’ah
Authors: Moh. Husnul Affan  , Asep Awaludin
Published: November 2023

The application of sharia in Islam is a matter that must be done, in the form of worship, mua'amalah and law. However, in legal practice, often the application of the Shari'ah encounters many obstacles in the form of protests or rejections from many parties. This is triggered by the conception of Human Rights (HAM) which has been raised by the West in the 19th century. Thus, it is widely stated that shari'ah in Islam, especially in the application of law (hudūd) is widely seen as treatment that is not in accordance with human rights. However, it turns out that the conception of human rights and humanity implied in it still has various epistemological and theological problems. Human rights that have been discoursed by the West are completely loaded with the paradigm of Humanism-Secular which is very contradictory in Islam. For this reason, Muslims design a separate conception of human rights that is in accordance with the Islamic worldview. So, in this article, the author will discuss the suitability of the purpose of implementing sharia or maqāṣid al-sharī'ah with humanity based on an Islamic view. The writing of this article uses qualitative research methods with a library research model. The writing of this article uses qualitative research methods with a library research model.
The Implementation of Qanun Jinayat in Aceh
Authors: Fauzah Nur Aksa  , Saifullah T , Farabi Al
Published: November 2023

Aceh is the only region in Indonesia granted special rights to implement Islamic law within its territory, as stipulated in Law No. 44 of 1999 regarding the administration of special autonomy in the Aceh Special Region. This uniqueness can be seen as a political solution to the long-standing conflict in Aceh. Several institutions serving as enforcers of Islamic law were established to support the implementation of local regulations on Islamic law, including the Sharia Court, the Sharia Office, and the Wilayatul Hisbah (WH). Additionally, the Aceh regional government collaborates with the police and the prosecutor's office, where they act as investigators, interrogators, and public prosecutors in the implementation of Islamic law. This research examines the implementation of the Qanun Jinayat in Aceh. The research findings indicate that the implementation of Islamic law in Aceh faces several challenges. Firstly, the Wilayatul Hizbah (WH) faces issues related to their authority, as according to Sharia rules, their role is limited to supervision, while investigation falls under the jurisdiction of the police. In practice, the police often disregard Islamic law in Aceh, mainly due to several provisions conflicting with national laws. Consequently, many cases of Sharia violations end with reconciliation processes within the police and do not proceed to court prosecutions. Secondly, the execution process is often lengthy, and in many cases, execution is neglected. The principles of equality before the law and legal certainty have not yet become primary principles in the application of Islamic law in Aceh.
The Position of the Indonesian Council of Ulama in The Indonesian State Governmental Legal System
Authors: Mahendra Sandya , Junaidi Muhammad
Published: November 2023

This study aims to 1) Know the position of the Indonesian Council of Ulama (MUI) in the Indonesian constitutional law system; 2) Knowing the MUI's position in Abu Hasan Al-Mawardi's (Al-Mawardi) thought. The method in this study uses normative legal research or doctrinal law with a philosophical, historical and conceptual approach. If viewed from a state institutional perspective, the MUI is in the realm of the political infrastructure area. Political Infrastructure itself is a group of institutions that exist in society. The MUI fatwa is not a type of statutory regulation that has binding legal force Based on Article 1 point 2, Article 7 paragraph (1) and Article 8 paragraph (1) of Law 12/2011, the MUI fatwa is not statutory regulation, because it is not made by an authorized body/or institution and does not have general binding power. However, the MUI fatwas are a source of material law. To become a positive law, the MUI fatwa must be positivized by the state through statutory regulations. The theory of state objectives developed by Al-Mawardi has two basic concepts, namely (1) formalization of Shari'a activities, (2) regulation of social, economic, political, legal and military activities.

Authors: García Castro Giovanni , Ruiz Ortega Francisco Javier
Published: November 2023

El libro “Argumentación clínica y multimodalidad: un aporte a la didáctica de las ciencias de la salud” aborda diferentes perspectivas teóricas y metodológicas que buscan comprender las dinámicas propias de la formación de talento humano en salud. Se incorporan avances de investigación en ciencias de la educación, la sociología y la lingüística a la investigación en didáctica especifica de la medicina. Se explora la argumentación clínica como una habilidad cognitivo-lingüística de orden epistémico, que aporta a la construcción de ciencia en “el aula”, considerando “el aula” de medicina en un sentido amplio, es decir, las rotaciones clínicas, la resolución de casos y las practicas con pacientes reales y en sitios reales. Adicionalmente, la multimodalidad, introducida al estudio de la argumentación provee nuevas perspectivas de análisis, que complementa el estudio de los discursos académicos en salud en medio de una comunidad que aprende mientras construye su propio lenguaje. Finalmente se incorpora la Teoría de legitimación de códigos (Legitimation Code Theory- LCT) de Karl Maton, que, desde su dimensión de autonomía, aporta al análisis comprensivo de la intencionalidad de los docentes de medicina en promover espacios de argumentación multimodal, momentos de debate y dialogo interactivo, como estrategia de consolidación de lenguajes especializados en salud.
Endoscopic management of sinus neoplasia: case series of image-guided surgery of inverted papillomata and recommended best practice for managing cases.
Authors: Klyvyte Gabi , Wong Jeremy , Gokani Shyam , Luke Louis , Jegatheswaran Lavandan , Philpott Carl
Published: November 2023

Key Points Inverted papillomata are benign sinonasal tumours
with high recurrence rates. Inverted papillomata recurrence is increased
if operated on by a non-fellowship trained rhinologist. Inverted
papillomata recurrence can be detected earlier in cases managed by
specialist rhinology services. Inverted papillomata should be managed
through a clear treatment pathway for sinonasal tumours. Other risk
factors associated with increased recurrence include Krouse stage 3 and
involvement of the frontal or maxillary sinuses.

Published: November 2023

Popcorn is a special kind of maize that can easily become popcorn flake
when heated under a given condition. However, its popping mechanism
remains unclear at present. Opaque2 (O2) was a central transcriptional
factor that play important roles during maize endosperm development. In
this study, an o2 introgression into N04 inbred line was constructed,
and the mutation of o2 reduced the popping rate of N04. In order to
reveal the underlying mechanism of O2 involved in popping
characteristics, the o2 introgression and popcorn inbred line N04 were
performed proteomic analysis at three development stage of their kernels
using the 8-plex iTRAQ reagents with three repetitions followed by
2D-LC-MS/MS spectra. A total of 5184 proteins were found, and 1073
proteins of which showed dynamics change. KEGG enrichment analysis found
that these dynamic changed proteins were significantly enriched in
carbon metabolism, pyruvate metabolism, citrate cycle, fructose and
mannose metabolism, starch and sucrose metabolism, and pentose phosphate
pathway. A total of 16 differentially expressed protein regulated by O2
were identified. These results preliminary uncover the molecular
mechanism of popping characteristics in popcorn.

Combined distalization and lingual cortex remodeling during mandibular growth for facial profile improvement: a case report
Authors: Giap Hai-Van , Jeon Ji Yoon , Chun Joo-Hee , Lee Kee-Joon
Published: November 2023

Borderline crowding poses a challenge in deciding whether or not to prescribe premolar extraction. This case report describes the two-phase nonextraction orthodontic treatment of an 11-year-old girl with a hyperdivergent skeletal Class I pattern exhibiting anterior crowding and moderate lip protrusion. The initial phase of treatment included maxillary and mandibular expansion to correct the transverse discrepancy as an early intervention. Subsequently, comprehensive treatment was initiated at the age of 13 years, with fully erupted permanent second molars and growth potential remaining. Phase II treatment involved a second round of maxillary expansion, followed by simultaneous bimaxillary total arch intrusive distalization, using interradicular, temporary skeletal anchorage devices to correct dental crowding and improve the facial profile. Although the limited retromolar space posed a challenge to mandibular tooth distalization, gradual bone remodeling was observed in the lingual cortex of the mandibular body, enabling sufficient orthodontic tooth movement without noticeable side effects. After 4 years 3 months of treatment, her dental crowding was relieved, with significant improvement in the facial profile and proper occlusion. The treatment outcomes remained stable 2 years 4 months after retention.

Construction of a Solar Still Prototype to Reduce Extreme Water Hardness in the Mayan Community Ejido 20 de Noviembre
Authors: Marines Castillo Edrai Elburit , Heredia Carrillo Erick Iroel , Garduño GarcÍa Claudia
Published: November 2023

Available water in natural sources at the Mayan community Ejido 20 de Noviembre presents extreme hardness; it exceeds the maximum limit established by Mexican regulations. Consequentially, the water found in these sources is not suitable for human consumption, a critical use for the villagers in drought seasons when water scarcity is more severe. Therefore, affordable alternatives are required to treat water resources that can be used locally. In this sense, the objective of the research was to develop a solar still prototype in order to test the technology’s performance in water treatment available in the community. The prototype development consisted of 6 stages: still model selection, dimension definition, 3D modeling, material selection, assembly, and prototype testing. The device testing at the community was carried out over a period of 3 days, during which well water with an initial hardness of 3500 mg/l CaCO3 was used. A significant hardness reduction was recorded after the solar distillation process, obtaining values of 119.3 mg/l CaCO3, which indicates that the solar distillation technology serves to reduce the water hardness of the community.
Neutronic Chain Reactions for Polonium-210 Production
Authors: Lim Solomon
Published: November 2023

The production of the industrially significant radionuclide polonium-210 from the neutron irradiation of bismuth metal and the subsequent beta decay of bismuth-210 is highly inefficient due to the small neutron capture cross section of bismuth-209. In this paper, we report a previously undescribed self-sustaining nuclear chain reaction involving self-propagating neutron multiplication in bismuth salts that allow for rapid and cost-effective production of polonium-210. The reaction proceeds in a cycle of three alternating elementary steps – the capture of neutrons by bismuth-209 and the subsequent formation of polonium-210, the emission of high-energy alpha particles by polonium-210, and the production of more neutrons from (α, n) and (n,2n) reactions on light element and bismuth-209 nuclei respectively. Furthermore, the high hydrogen density of the compound also confers it intrinsic neutron moderation properties, increasing the neutron capture cross section of bismuth-209 at thermal neutron energies. The chain reaction was proven to have successfully occurred by irradiating a sample of the bismuth salt with a 80 μCi neutron source and monitoring the activity levels of the reaction. It was found that the activity of the reaction increased exponentially after an initial stable period following a derived formula for polonium production trends for the reaction, thus validating the occurrence of the reaction. Furthermore, alpha spectroscopy confirmed that polonium-210 had been produced by characterising the 5.30 MeV alpha emission peak of the reaction in addition to using beta spectroscopy to identify the parent nuclide bismuth-210, further proving that the reaction was successful. Hence, this paper reports the successful initiation and characterisation of a novel nuclear chain reaction, and its potential applications offered by a method of rapidly producing large quantities of polonium-210.
FUTURES PRICES LINKAGES IN THE US SOYBEAN COMPLEX
Authors: Fousekis Panos
Published: November 2023

This work investigates the linkages among the futures prices of soybeans, soybean meal, and soybean oil in the US. This has been pursued using a flexible methodology that allows modelling price relationships at different parts of their joint distribution. According to the empirical results, the markets are strongly connected in the vertical direction regardless of the sign and the size of shocks. The meal and oil prices maintain a negative relationship at the median and the upper quantiles but they are not connected under large negative shocks. The soybean market is a net transmitter of price risk to the other two markets while price shocks around the median tend to be transmitted with higher intensity relative to those at the extremes.
Entre reciclajes y reconfiguraciones: una aproximación textual, transmedial y sociocultural al fenómeno de la fanfiction
Authors:   , Gil Cruz Brenda Melina
Published: November 2023

Este trabajo propone una serie de aproximaciones al fenómeno de la fanfiction, a fin de problematizar su carácter heterogéneo y sus posibilidades y limitaciones en los lindes de un circuito pragmático y un circuito semántico. Consciente de los límites de la disciplina literaria y sus herramientas operativas, esta investigación se articula desde una impronta interdisciplinaria, que reúne esfuerzos del ámbito de las comunicaciones y los estudios de la cultura. De ese modo, entre los tratamientos que se desglosan de forma significativa, mas no exhaustiva, se discuten no solo las textualidades de los aficionados, sino las relaciones que ellas mismas suponen en los procesos de construcción de identidades individuales y colectivas. Asimismo, dichas textualidades se discuten en relación con las expansiones narrativas y, en menor grado, con las extensiones mediales de sus principales marcos de referencia: Harry Potter y BTS. Desde luego, en este trabajo, que recupera un objeto de estudio poco privilegiado por las academias literarias, no se pretende emular una dinámica de abordaje desde una veta exclusivamente comparativa entre hipotextos e hipertextos. Más bien, se busca, con base en una problematización de las lógicas, valores y dinámicas de producción, distribución y recepción del fenómeno en el medio digital, colocar la atención en las contingencias que derivan de un intercambio incesante entre capas textuales. Mismas que permanecen imbricadas a una práctica cultural cada vez más visible e importante entre adolescentes y jóvenes de todas latitudes.
El monstruo ancestral en el relato mexicano contemporáneo 1952-2014
Authors:   , Juárez Becerril Oscar
Published: November 2023

La literatura fantástica indaga en la transgresión de los límites de la cabalidad, en la irrupción fulminante de un elemento insólito dentro del paradigma de realidad. Al enfrentarnos con una aparente sinrazón, el panorama del entorno conocido, se amplía. En este sentido, el monstruo aparece como un personaje transgresor en sí mismo, una figura que, con base en los miedos que encarna y que manifiesta, rompe con el modelo de realidad. Este trabajo tiene como propósito revisar la presencia del monstruo ancestral en el relato mexicano contemporáneo, mediante diez relatos publicados entre 1952 y 2014. Contemplo principios teóricos del monstruo, de la literatura fantástica, del mito, de la leyenda. Analizo los rasgos corporales de cada uno de los personajes monstruosos, los recursos de los narradores para ambientarlos, así como las diferentes referencias y contextos en los que se presentan. Con base en lo anterior, cada texto aporta características propias a su cualidad fantástica. El monstruo aparece como la proyección de lo humano: de su actuar, de sus creencias, pero sobre todo de los errores que no solemos atribuirnos; relegándole, de esta forma, nuestras culpas. Igualmente, las obras analizadas afincan el pasado del mexicano, lo revelan, lo proyectan hacia la contemporaneidad. Este ejercicio de recolección de quimeras, se convierte en una especie de bestiario contemporáneo que refleja las preocupaciones de la sociedad mexicana enfocadas en su origen, en su historia, en el presente que se pierde a cada minuto y que decanta en un futuro nebuloso.

Mackerel is a small pelagic fish that has potential value and can be found throughout Indonesian waters. It is feared that high exploration activities will have an impact on the population. Sampling was carried out at the fish landing port and fish auction place (Bacan, Morotai and Ternate). The sample was photographed and the 3 cm swimming fin was taken. The sample is then stored in a tube that has been filled with 96% ethanol solution. The next stage is the process of extraction, amplification, electrophoresis and DNA sequencing. Phylogenetic reconstruction of comparison of primary data (Bacan, Morotai and Ternate) and secondary data (Indian) clarified to form two different populations (clades). Amova population pairwaise (Fst) showed the genetic flow of R. kanagurta population in the waters of the north Maluku Sea (Bacan, Morotai and Ternate). On the other hand, genetic distance shows that populations (Bacan, Morotai and Ternate) were closely related and have strong genetic connectivity.
Reduced Sensitivity to Fluopyram in Meloidogyne graminis following Long-Term Exposure in Golf Turf
Authors: Kammerer Christian L. , Harmon Philip F. , Crow William T.
Published: November 2023

In recent years, some golf course superintendents in Florida have reported that the turf health is no longer as great, and nematode responses to fluopyram have decreased. The objective of this research was to determine if the mechanism of the reported reduced efficacy was attributable to either: i) enhanced degradation accelerating its breakdown in the soil, or ii) reduced sensitivity to the nematicide in the nematode populations. In a field experiment, soil and nematodes were collected from small plots that had been treated multiple times over four years, for only one year, or never treated. Soil and nematodes were additionally collected from commercial turf sites where either multiple applications of fluopyram had been made for numerous years, or it had never been used. Bioassay experiments found no evidence of enhanced degradation. However, M. graminis collected from small field plots and commercial sites with long-term use of fluopyram were less sensitive to fluopyram in-vitro than those from small plots and commercial sites where fluopyram had not been used. These results indicate that nematicide resistance is a likely cause of reduced fluopyram efficacy on golf-course turf in Florida.

El biochar alcalino es una alternativa por su estabilidad y capacidad de obtener un balance positivo de carbono, mejorar los suelos agrícolas y generar menores emisiones de GEI. La emisión de CO2 y las propiedades físicas y químicas de un suelo ácido al ser enmendado con biochar, cal, dolomita agrícola versus un testigo (sin enmienda) se evaluaron en invernadero. Sin cultivo, la cal agrícola y biochar tuvieron una rápida reacción elevando el pH cerca de 7; el biochar aumentó el contenido de materia orgánica (+23%), nitrógeno (+20%), fósforo disponible (+116%), CIC (+46%) y cationes intercambiables. La emisión de CO2 temporal dentro de las 24 horas, aumentó con el biochar (+131%) y dolomita (+41%), aunque después disminuyó significativamente. Con el cultivo de maíz, el biochar mantuvo el valor deseado de pH, fueron mayores el fósforo (+109%) y potasio disponible (+224%), CIC (+6%) y cationes intercambiables; la emisión temporal dentro de las 24 horas fue mayor para el biochar (+314%), cal (+115%) y dolomita (+112%); y para el CO2 acumulado, el biochar presentó el mayor valor (+53%). Al día 56, las emisiones de CO2 no fueron significativamente diferentes al testigo para las tres enmiendas, y menores a partir del día 75, lo cual significaría una reducción en las emisiones a largo plazo.

Antibiotic-Resistant Bacteria (ARB) bacteria were triggered by inappropriate antibiotic therapy. Bacterial resistance can be monitored through surveillance of bacterial growth pattern and their susceptibility to antibiotics. This study presents a sensitivity profile of pathogenic bacteria, isolated from clinical specimens, against various antibiotics. The present description was based on a secondary data that was obtained from a series of sensitivity test that was conducted between January 2019 and December 2021 in UPTD Balai Laboratorium Kesehatan Provinsi Bali. All data was processed using WHONET 2021 software and further calculated using Ms. Excel 2007. From a total of 419 samples taken from an average age of 40.7±17.9 years, 332 showed positive cultures, with females being the majority (55.7%). The positive cultures consist of 125 urine specimens (37.7%), 79 feces(23.8%),49 eyes (14.5%), 29 throat swabs (8.7%), and 21 sputum specimens (6.3% ). The Gram positive group was dominated by Staphylococcus sp. 73 (54.5%) and Streptococcus sp. 40 (29.9%), while the Gram negative group was dominated by E. coli 71 (35.9%) and EPEC 33 (16.7%). The Gram negative bacteria showed highest sensitivity to amikacin (83.8%), the lowest to erythromycin (1.5%). The Gram positive bacteria were most sensitive to doxycycline (68.6%) and the least sensitive to cefixime (9%). Six pathogen that commonly cause nosocomial infections, demonstrated increased resistance to antibiotics: E. coli to chloramphenicol, ofloxacin, and levofloxacin; EPEC to cefazoline, ceftriaxone, cefixime, and levofloxacin; Klebsiella sp. to amikacin; P. aeruginosa to ceftazidime, amikacin, ciprofloxacin, gentamicin, ceftriaxone, and piperacillin; S. aureus to tetracycline, amoxicillin, and azithromycin; Streptococci to ceftazidime, erythromycin, doxycycline, and levofloxacin. This analysis provides referrals for medical personnel in healthcare facilities to use appropriate antibiotics.

Microchirita caerulea (R. Br) Yin Z.Wang is a Gesneriaceae plant endemic to Java and the Lesser Sunda Islands. The genus is a section of Henckelia with very little information in anatomical studies. The research aims to contribute to the anatomical study of the Microchirita, particularly M. caerulea from Madura. The observation made paradermal slides and transversal incisions of the leaf blade, petiole, and stem. The results showed diacytic and copericytic stomatal characteristics, with only mesophyll palisade found. The large leaf primary veins' abaxial epidermis, collenchyma, and petiole parenchyma. The vascular bundles consist of xylem and phloem in the stem's leaf stalk and petiole and phloem fibers. No sclerenchyma and secretory ducts were found on the petiole. The arrangement of the vascular bundles in the leaf bones is thought to be a new variation of the arrangement in Gesneriaceae. The arrangement of the vascular bundles on the petiole and stem resembles several species of the Henckelia genus.

Utilizing the potential of local rice is a promising venture in the development of superior drought -resistant rice. One of the local rice that comes from Lampung is the Lumbung Sewu Cantik variety. The purpose of this study was to evaluate the physiological resistance response of Lampung local rice shoots varieties Lumbung Sewu Cantik to the drought stress caused by PEG 6000 through relative water content and peroxidase enzyme activity. This study was conducted using factorial randomized design with 2 factors. Factor 1 is rice varieties (INPAGO 8 (K +), IR 64 (K-), and Lumbung Sewu Cantik). Factor 2 was the concentration of PEG 6000 (0% and 20%). Each treatment combination was repeated 3 times. Data were analyzed for variance and further analysis used DMRT test. The results showed that the drought stress did not have a significant effect on the relative water content of the rice shoots, but had a significant effect on the increase of peroxidase enzyme activity from the rice shoots. The results showed an increase in relative water content (2%) in rice shoots of Lumbung Sewu Cantik variety after being stressed by drought, while both controls experienced a decrease in relative water content. Shoots rice of Lumbung Sewu Cantik variety also experienced the highest increase in peroxidase enzyme activity (0.215 (U / mg)/min) when compared to the two controls. Furthermore, the results of DMRT test at 5% level showed that the activity of peroxidase enzyme activity from rice shoots of Lumbung Sewu Cantik variety was not much different from K- but significantly different from K+. Based on the test results of relative water content and peroxidase enzyme activity, it can be concluded that Lampung local rice, Lumbung Sewu Cantik variety, shows drought tolerance in germination phase and potential to develop into superior drought resistant rice varieties.
