Towards Alternative Energy Sources: Is it Time to Switch to Nyamplung?
Authors: Siagian Abdhy Walid , Daffa Alghazali Muhammad Syammakh
Published: February 2023

Nyamplung is one of the six priority non-timber forest products in Indonesia. This type of mangrove has a high yield of oil as a raw material biofuel with a 40-70% higher percentage than other plants, such as oil palm, whose percentage is only 46-54%. This article examines Indonesia's commitment to accelerate the transition to new and renewable energy through biofuels to meet the national electricity supply. In addition, it conducts an economic calculation of nyamplung as alternative energy for biofuels. The writing of this article reflects an economic analysis of law that combines legal analysis based on norms, guidelines, and plans as stipulated in Indonesian laws and regulations and international instruments and economic analysis referring to relevant data and sources. This article concludes that nyamplung may serve as an alternative energy source to fulfill future national energy needs, which aligns with efforts to achieve a sustainable environment. Despite laws and policies on national energy supporting any efforts to complement and substitute current energy sources, the utilization of nyamplung has yet to be optimized as a biofuel.

In this article, the eigenvalues and inverse of circulant matrices with entries in the first row having the form of a geometric sequence are formulated explicitly in a simple form in one theorem. The method for deriving the formulation of the determinant and inverse is simply using elementary row or column operations. For the eigenvalues, the known formulation of the previous results is simplified by considering the specialty of the sequence and using cyclic group properties of unit circles in the complex plane. Then, the algorithm of eigenvalues formulation is constructed, and it shows as a better computation method.

EFL Teacher’s Strategies in Preparing Classroom Activity for Vocational High School Students
Authors: Ardiansyah Fauzi
Published: February 2023

The research reported on teachers’ strategies in preparing classroom activities for vocational high school students. It was obvious that vocational school prepares students to work in particular industries. Thus, the teacher can provide classroom activities that were able to increase the student’s skills. A case study methodology was employed in this research and the data were obtained from classroom observation and non-structured interviews. The topic of this research is an English teacher at a vocational high school. The result found that the teacher prepared the learning materials based on the major that the student had taken and provided the classroom activity that adjusted to the student’s skill program. However, the study also showed that many students still seemed unmotivated and less focused. The teacher explained that it could be the students' less vocabulary mastery that made them hard to pay attention to the learning activity. The findings concluded that (1) the teacher can provide effective classroom activities even though it is still hard to manage the students, and (2) the teacher has provided the classroom activities based on the student’s needs, backgrounds, and skills.

Published: February 2023

Iron oxide nanoflowers can be synthesized through a polyol route firstly introduced almost 2 decades ago by Caruntu et al, presenting multi-core morphology, several grains (around 10 nm) being attached together (and obviously sintered). These IONFs present outstanding properties for magnetic field hyperthermia, which is considered as promising therapy against cancer. Although they have a significantly smaller diameter, the specific adsorption rate (SAR) of IONFs can reach values of the order of 1 kWg-1, as large as for magnetosomes that are natural magnetic nanoparticles typically ~40 nm found in certain bacteria, which can be grown artificially but with lower yield compared to chemical synthesis. This work aims at better understanding the structure-property relationships between the internal nanostructure of IONFs as observed by HR-TEM and their properties, in particular magnetic ones. A library of mono and multicore IONFs is presented, with diameters ranging from 11 to 30 nm and narrow size dispersity. By relating their structural features (diameter, morphology, defects) to their magnetic properties investigated in particular by AC magnetometry over a wide range of alternating magnetic field (AMF) conditions, the SAR values of all synthesized batches vary with overall diameter and number of constituting cores in qualitative agreement with theoretical predictions by the Linear Response Theory (LRT) at low fields or with the Stoner-Wohlfarth (SW) model for larger amplitudes, and with numerical simulations reported previously, in particular by showing a pronounced maximum at an IONF diameter of 22 nm.

Published: February 2023

Liposomes containing high-spin Fe(III) coordination complexes were prepared towards the production of MRI probes with improved relaxivity and rapid pharmacokinetic clearance in mice. The amphiphilic Fe(III) complexes were anchored into the liposome with two alkyl chains to give a coordination sphere containing mixed amide hydroxypropyl pendant groups. Three types of MRI probes were prepared including those with intraliposomal Fe(III) complex (LipoA) alone, amphiphilic Fe(III) complex (LipoB) or both intraliposomal and amphiphilic complex (LipoC). Water proton relaxivities r1 and r2 were measured and compared to a small molecule macrocyclic Fe(III) complex containing similar donor groups. Liposomes with amphiphilic Fe(III) complex (LipoB) have a per particle relaxivity of 37,000 and a per iron relaxivity of 2.6 mM-1s-1 in solutions with pH 7.2, 34 C at 1.4 T. Liposomes containing both amphiphilic and intraliposomal Fe(III) complexes (lipoC) have reduced per iron relaxivity of 0.8 mM-1s-1 in solution consistent with quenching of the interior Fe(III) complex relaxivity and per particle relaxivity of 42 ,000 mM-1s-1. Liposomes containing only encapsulated Fe(III) complex have a lower relaxivity of 0.46 mM-1s-1 per iron complex. Studies show that lipoB and lipoC produce enhanced signal in the CT26 tumors of BALB/c mice. However, the biodistribution and clearance of the liposomal nanoparticles differs greatly. LipoB is a blood pool agent with a long circulation time whereas lipoC is cleared more rapidly through both renal and hepatobiliary pathways.

Pain management is one of the oldest challenges for medicine. Although opioids have been used in the treatment of moderate-to-severe acute and chronic pain for centuries, they cause various adverse effects and addiction. The intertwined societal, economic and public health issues of pain management and the risks of opioid abuse continue to receive attention and drive the development of safer analgesics. Recently, a kratom metabolite, mitragynine pseudoindoxyl has attracted increasing attention as a promising analgesic alternative for pain management with considerably fewer side effects. Here, we describe the first enantioselective and scalable total synthesis of this natural product in addition to its C-20 epimeric congener, speciogynine pseudoindoxyl. The characteristic spiro-5-5-6 tricyclic system of these alkaloids is formed via a protecting group-free cascade relay process in which oxidized tryptamine and secologanin analogs are used. Furthermore, we uncovered that mitragynine pseudoindoxyl exists and acts not as a single molecular entity but as a dynamic ensemble of stereoisomers in protic environments, thus, it exhibits structural plasticity in biological systems. Accordingly, these synthetic, structural, and biological studies provide a basis for the planned design of mitragynine pseudoindoxyl analogs, which can guide the development of next-generation analgesics.
Ab Initio Molecular Cavity Quantum Electrodynamics Simulations Using Machine Learning Models
Authors: Hu Deping , Huo Pengfei
Published: February 2023

We present a mixed quantum-classical simulation of po- lariton dynamics for molecule-cavity hybrid systems. In particular, we treat the coupled electronic-photonic de- grees of freedom (DOFs) as the quantum subsystem and the nuclear DOFs as the classical subsystem and use the trajectory surface hopping approach to simulate non- adiabatic dynamics among the polariton states due to the coupled motion of nuclei. We use the accurate nu- clear gradient expression derived from the Pauli-Fierz Quantum Electrodynamics Hamiltonian without mak- ing further approximations. The energies, gradients, and derivative couplings of the molecular systems are obtained from the on-the-fly simulations at the level of complete active space self-consistent field (CASSCF), which are used to compute the polariton energies and nuclear gradients. The derivatives of dipoles are also necessary ingredients in the polariton nuclear gradient expression but are often not readily available in elec- tronic structure methods. To address this challenge, we use a machine learning model with the Kernel ridge re- gression method to construct the dipoles and further ob- tain their derivatives, at the same level as the CASSCF theory. The cavity loss process is modeled with the Lindblad jump superoperator on the reduced density of the electronic-photonic quantum subsystem. We inves- tigate the azomethane molecule and its photoinduced isomerization dynamics inside the cavity. Our results show the accuracy of the machine-learned dipoles and their usage in simulating polariton dynamics. Our po- lariton dynamics results also demonstrate the isomer- ization reaction of azomethane can be effectively tuned by coupling to an optical cavity and by changing the light-matter coupling strength and the cavity loss rate.
Thermofluorimetric Analysis (TFA) using Probes with Flexible Spacers: Application to Direct Antibody Sensing and to Antibody-Oligonucleotide (AbO) Conjugate Valency Monitoring
Authors: Kurian Amanda , Gurukandure Asanka , Dovgan Igor , Kolodych Sergii , Easley Christopher
Published: February 2023

Antibodies have long been recognized as clinically relevant biomarkers of disease. The onset of a disease often stimulates antibody production at low quantities, making it crucial to develop sensitive, specific, and easy-to-use antibody assay platforms. Antibodies are also extensively used as probes in bioassays, and there is a need for simpler methods to evaluate specialized probes such as antibody-oligonucleotide (AbO) conjugates. Previously, we have demonstrated that thermofluorimetric analysis (TFA) of analyte-driven DNA assembly can be leveraged to detect protein biomarkers using AbO probes. A key advantage of this technique is its ability to circumvent autofluorescence arising from biological samples, which otherwise hampers homogenous assays. The analysis of differential DNA melt curves (dF/dT) successfully distinguishes the signal from background and interferences. Expanding the applicability of TFA further, here-in we demonstrate a unique proximity based TFA assay for antibody quantification which is functional in 90% human plasma. We show that conformational flexibility of the DNA-based proximity probes is critically important for optimal performance in these assays. To promote stable, proximity-induced hybridization of the short DNA strands, substitution of polyethylene glycol (PEG) spacers in place of ssDNA segments led to improved conformational flexibility and sensor performance. Finally, by applying these flexible spacers to study AbO conjugates directly, we validate this modified TFA approach as a novel tool to elucidate the probes valency, clearly distinguishing between monovalent and multivalent AbOs and reducing the reagent amounts by 12-fold

Efficient utilization of triplet excitons is vital in organic optoelectronics. One important strategy for harvesting triplets is thermally activated delayed fluorescence (TADF). In most TADF materials, the first singlet (S1) and triplet (T1) excited states both show strong charge-transfer (CT) character to reduce their energetic gap (EST); however, the negative consequence is small spin-orbit coupling and broad fluorescence emission width. To overcome this trade-off, our present work developed a novel strategy, i.e., intermolecular pi-pi-packing-induced (pi3) TADF, named pi3TADF. Distinct from the previously reported TADF systems, the excited states of our intermolecular pi3TADF systems show weak CT-excitation character. Our designed coplanar molecules based on a 1,5,9-trioxo-13-azatriangulene core show low photoluminescent quantum yields (PLQYs) in dilute solutions while their PLQYs in solid films reach ~ 100%. Their face-to-face pipi packings lead to the hybridization of intermolecular CT and localized pi-pi* excitations as well as electronic delocalization in the S1 states, while their T1 states show little changes. Consequently, with a dense manifold of the triplet states, the EST is significantly reduced while the large spin-orbit couplings are induced, thus leading to efficient TADF and significantly enhanced PLQYs in films. Organic light-emitting diodes exploiting the intermolecular pi3TADF systems as emitters show simultaneously high maximum external quantum efficiencies (e.g., over 30%) and narrow emission spectral widths (e.g., 44 nm). Our present work not only develops a new strategy, i.e., pi3TADF, for efficient TADF but also provides an in-depth understanding of its photophysical mechanism, thus opening a new approach for designing novel and efficient TADF materials.

Abstract

 

Indonesia is a country that has a very high level of vulnerability to earthquakes. However, it is very rare for bridges in rural areas or in sub-districts to be evaluated or screened. As a result, many bridges are prone to damage when seismic earthquakes occur, even though bridges are an important infrastructure for the village for the village's economic progress. This research was conducted with the aim of conducting a quick seismic inspection of the bridge and obtaining a priority order for bridge repair using the Seismic Vulnerability Index (SVI) method. The analysis was carried out on the sample, which consisted of 4 bridges located in Pati Regency. The results of the SVI analysis show that of the 4 observed bridges, the Tanjang Bridge has the highest Seismic Vulnerability Index, so it is recommended that this bridge get the first repair priority.

Parasitos do gênero Toxocara, em especial Toxocara canis, destacam-se pela sua elevada prevalência e potencial zoonótico. Em virtude das altas taxas de parasitismo, associada ao desenvolvimento de resistência aos antihelmínticos pelos parasitos intestinais de cães e gatos, torna-se necessária a descoberta de novas opções. Assim, o objetivo desse estudo foi verificar a composição química e a atividade antihelmíntica in vitro de óleo essencial de plantas da família Lamiaceae frente a ovos e larvas de Toxocara spp. Para isso, a análise da composição dos óleos foi realizada utilizando a técnica de cromatografia gasosa e para avaliação da atividade antihelmíntica foram realizados testes ovicidas e larvicidas com seis diferentes concentrações dos óleos essenciais. Nos testes ovicidas, o óleo essencial de Origanum vulgare apresentou eficácia superior a 98,45%, nas concentrações superiores ou igual a 0,37mg/mL, enquanto Origanum majorana nas concentrações de 6 a 0,37mg/mL mostrou eficácia de 100%. Rosmarinus officinalis nas concentrações avaliadas (6 a 0,18mg/mL) não apresentou eficácia (inferior a 71,47%). Na atividade larvicida o óleo essencial de O. vulgare (6 a 0,37mg/mL) e o de O. majorana (6 a 1,5mg/mL) apresentaram eficácia superior a 97,88%, enquanto o de R. officinalis apresentou eficácia superior a 95,13% somente nas concentrações de 6 a 3%. Os resultados demonstraram que os óleos essenciais de O. vulgare, O. majorana e R. officinalis, possuem atividade ovicida e larvicida frente a ovos e larvas de Toxocara spp., sendo assim uma possível alternativa futura para o controle deste parasito zoonótico, a partir de estudos do mecanismo de ação e de toxicidade desses óleos.
Resignificando la educación: una apuesta desde la complejidad
Authors: Rodríguez Becerra Luz Amanda
Published: February 2023

La educación ha experimentado cambios y adaptaciones en diversos contextos y períodos del acontecer humano de manera natural y como consecuencia de sucesos provocados por la injerencia de gobiernos, religiones y grupos económicos, entre otros. Es hora de que, desde las ciencias de la complejidad, como una de las ciencias de punta, se brinde también apoyo y fundamentos, con un diseño no experimental aplicado transversal y comparativamente, con base epistemológica constructivista y enfoque mixto, en este artículo se pretende deducir los posibles aportes de la complejidad a la resignificación de la educación en el contexto en que la humanidad vive de manera más globalizada, reconociendo la complejidad de aprendiente, del mediador y del entorno. Se debe precisar que la educación no es un aspecto que reduce los grados de libertad que cada individuo tiene, sino que aprovecha las posibilidades del contexto globalizante actual. En ese sentido, las ciencias de la complejidad formulan un nuevo problema: ¿qué es la educación? Este nuevo ámbito de las ciencias quiere dar soporte a la gestión de las políticas públicas con un modelado apoyo en cuanto a la tecnología, el arte, las ciencias y la filosofía que pueda mostrar los efectos de su aplicación en la opción de indisciplinar la sociedad para resignificar la educación, lo cual es una necesidad de hoy con proyección a mediano y largo plazo.

Este artículo presenta los principales aspectos ling¨uísticos de las LS y su influencia ling¨uística en la conformación de la poesía, comparándolos con los de la poesía oral. Sobre la poesía general, parece necesario plantearse la cuestión del problema te´órico de la misma. Esta idea se asocia al fonocentrismo, idea de la que Derrida habla en profundidad en sus estudios. Este autor se refiere a la necesidad de deconstruir el concepto de poesía que se ha estudiado hasta ahora, ya que no incluye ni reconoce la poesía signada como parte esencial de la poesía global debido a su nula sonoridad. Este estudio demuestra que el ritmo poético ya no es un concepto exclusivo de las lenguas orales y, asimismo, permite comprender cómo funciona la poesía sin fonía en las LS.
Forgetting (Al-Nisyān) Therapy: An Islamic Insight

Published: February 2023

The capacity of memory in the brain to store, process, and recall information is truly a wondrous blessing. Forgetfulness may be a blessing from Allah to make life easier by allowing humans to forget bad events and shocks from the past. However, increased forgetfulness can lead to issues such as forgetting the Quran and other important information and being unable to concentrate. The questions that arose were how forgetfulness hinders humans in a variety of situations and circumstances, as well as its impact on living a healthy life. Using a descriptive qualitative method, this study investigated how Islam explains forgetting, its causes, and its cures from a scientific and spiritual standpoint. This study also revealed treatments that can be done to overcome this disease and circumvent negative impressions. This article found some tips to strengthen memory, such as reciting dhikr (remembrance), maintaining a well-balanced diet, reading books, memorizing the Quran, and participating in frequent prayer, which are all excellent ways to exercise a Muslim's mind.

Motivation is a crucial concept for being successful in learning. Highly motivated students will do their best in learning any subject. This quantitative study aimed to investigate the predominant type of motivation among Gayonese students and their level of motivation to study English at the Department of English Language Education, Universitas Islam Negeri Ar-Raniry Banda Aceh. The research samples were 33 students from batch 2014 to batch 2018 from the Department of English Language Education from Gayo highland Districts (Central Aceh, Gayo Lues, and Bener Meriah Districts). The random sampling technique was used to select participants with close-ended questionnaires as the data collection instrument. The results showed that the overall intrinsic motivation score was greater than the extrinsic one (4.21 ˃ 3.05). As a result, the implication of this study requires teachers to boost students’ extrinsic motivation to increase their academic achievement in studying English at the university.

One of the problems in mixed marriages of different nationalities is joint property. Most mixed-married couples do not make property separation agreements because they are unaware that the Marriage Law governs them. The absence of a marriage agreement results in a mix of assets, which means that foreigners own half of the joint property. The provisions in the land law/ UUPA state that foreigners are prohibited from having land rights except for usufructuary rights and rental rights. This study applied the normative legal research method with a statutory and case-based approach. This study showed that if mixed marriage actors did not have a property separation agreement, Indonesian citizens' land rights ownership status was equal to that of the foreigners. Second, jurisprudence still required a separation of properties in mixed marriages. The agreement could be made before, during, or after the marriage. Third, marriage institutions could conduct legal smuggling to obtain land rights in Indonesia through borrowing names (nominees), usually carried out in an unregistered marriage.

The aim of the study was to evaluate the effectiveness of colostral immunity against aetiological agents of bovine respiratory disease complex (BRDC), to assess the suppressive effect of colostral antibodies againstMannheimia haemolyticaon immunity, and to analyse acute phase proteins in calves. Holstein-Friesian and Simmental cows and calves were immunized withM. haemolyticaleukotoxin (Lkt) and outer membrane proteins (OMPs) at 6 and 4 weeks before parturition. Sera and colostrum were collected from the cows directly after calving. Sera from calves were obtained before colostrum intake and 48 h after birth. Calves from vaccinated and unvaccinated cows were placed in the feedlot and immunized with Lkt or OMP on days 10 and 24. Calves were tested for serum antibodies against respiratory viruses. Trachea and lung samples were collected for bacteriological examination from all calves that had died with BRDC. The results indicated high colostrum values and IgG transfer in calves at 48 h (> 12.5 g/l) and a high concentration of anti-BVD antibodies in calves at 48 h (> 33–45 mg/ml). Similar values were observed for bovine herpes virus BHV-1 and bovine respiratory sycytil virus BRSV. Immunoglobulin concentrations were highest for antibodies specific to parainfluenza PI-3 and adenoviruses. The lowest antibody levels were detected againstM. haemolyticaantigens in all experimental groups of calves (< 50 mg/ml in calves of cows vaccinated withM. haemolyticaantigens and < 25 mg/ml in calves of unvaccinated cows). The findings indicate the need for early immunization of calves, which is often precluded by stress associated with transport and adaptation to the new conditions in the feedlot.

Manual therapies, physiotherapy, and modalities are often used as a treatment and prophylactic method for preventing various injuries, as well as a rehabilitation tool in the post-operative, traumatic period for horses. Significant results have been achieved with these therapies: increased joint range of motion, tissue extensibility, and reduced pain and inflammation. This study evaluated the effect of osteopathic manual therapy (OMT) on the nervous and immune systems, as well as on the hypothalamus-pituitary-adrenal (HPA) axis. To assess changes in these systems, non-invasive biomarkers were chosen: the heart rate (HR), respiratory rate (RR), temperature (T), as well as objective measurements: blood serum cortisol (BSC) concentration and white blood cell (WBC) count. A total of 30 thoroughbred horses were randomly divided into an experimental group (n = 15) and a control group (n = 15). Blood samples and physiological indicator measurements such as HR, RR, T, BSC and WBC were taken before (p0), after (p1) and one hour after (p2) the OMT treatment for the experimental group. Analogical sequence was performed for the control group without OMT. A significant increase of BSC by 0.94 µg/dl after OMT suggest a direct influence on the HPA axis. Also, a substantial decrease of WBC by 0.57 × 109/l indicates the immune system’s response to the treatment. Moreover, an observed significant decrease in HR and RR shows that the autonomic nervous system was affected by activating the parasympathetic nervous system. Based on the results obtained, it is concluded that OMT has an effect on the HPA axis and on the nervous and immune systems.
