Amyloid fibril formation is involved in various human diseases, such as amyotrophic lateral sclerosis and Parkinson’s disease. Many amyloidogenic proteins undergo liquid–liquid phase separation (LLPS), forming liquid-like droplets of condensed proteins. Although these droplets represent potential amyloid nucleation sites, the kinetics of amyloid nucleation in droplets is poorly understood owing to the lack of quantitative analytical methods. This study aimed to develop a measurement method for the determination of amyloid droplet nucleation rate based on image analysis. Here, the prion determinant domain of the yeast prion protein Sup35 (Sup35NM), which is known as a model protein of prion diseases, was used for demonstration. Droplets (1–20 µm in size) of Sup35NM were fixed in agarose gels, and amyloid nucleation in each droplet was counted via confocal microscopy. From the comparison of the amyloid nucleation rates in the droplets and aqueous solutions, we found a critical concentration (C*) of Sup35NM: amyloid nucleation is suppressed by LLPS above C*, whereas it is enhanced below C*. These results highlight that droplet formation can suppress amyloid nucleation, contrary to current hypotheses in which the amyloid nucleation is enhanced by droplet formation. The proposed quantitative measurement method can provide accurate assessment of the role of LLPS for amyloidosis-related proteins from pathological perspectives.

The hemiterpene isoprene is a volatile C5 hydrocarbon with industrial applications. It is generated today from fossil resources, but can also be made in biological processes. We have utilized engineered photosynthetic cyanobacteria for direct, light-driven production of bio-isoprene from carbon dioxide, and show that isoprene in a subsequent photochemical step, using either near-UV or simulated or natural solar light, can be dimerized into limonene, paradiprene, and isomeric C10H16 hydrocarbons (monoterpenes) in high yields under photosensitized conditions (above 90% after 44 hours with near-UV and 61% with simulated solar light). The optimal sensitizer in our experiments is di(naphth-1-yl)methanone which we use with a loading of 0.1 mol%. It can also easily be recycled for subsequent photodimerization cycles. The isoprene dimers generated are a mixture of [2+2], [4+2] and [4+4] cycloadducts, and after hydrogenation this mixture is nearly ideal as a drop-in jet fuel. Importantly the photodimerization can be carried out at ambient conditions. However, the high content of hydrogenated [2+2] dimers in our isoprene dimer mix lowers the flash point below the threshold (38 °C), yet, these dimers can be converted thermally into [4+2] and [4+4] dimers. When hydrogenated these monoterpenoids fully satisfy the criteria for drop-in jet fuels with regard to energy density, flashpoint, kinematic viscosity, density, and freezing point. Life-cycle assessment results show a potential to produce the fuel in an environmentally sustainable way.
Perancangan Alat Monitoring Arus Bocor pada Kabel 20 kV Menggunakan Filter Kalman Berbasis Internet of Things
Authors: Sitanggang Adi Franata H , Prabowo Yuliyanto Agung
Published: November 2022

One of the problems that often occurs in the use of ground cables is insulation failure. This condition can cause leakage current in the 20 kV cable on the secondary side of the transformer. The greater the value of the leakage current, the more heat will cause the insulation to worsen. If this condition is not handled immediately, it can lead to the opportunity for a short-circuit current between the phase and ground. Therefore, an Internet of Thing-based monitoring tool is needed that can determine the amount of leakage current contained in the 20 kV cable on the secondary side of the transformer by applying the Kalman filter method and sending it to the substation operator using Wifi. Based on the test, it was found that the implementation of this monitoring tool obtained more constant measurement results than the actual measurement value using a measuring instrument with an average error per phase, 1.5594% phase R, 1.5535% phase S, 1.5548% phase T.

The maximum output voltage of the audio amplifier is limited to the magnitude of the power supply voltage of the power transistor or the operational amplifier on the final amplifier. This limits the maximum power of the audio amplifier output. The way to enlarge the output power of the audio amplifier without increasing the voltage is the bridge method or bridged modes. With this method a bridge amplifier will be generated. This Bridge Amplifier is also known as Bridge-Tied Load (BTL) or Bridged Transformerless. The principle of Bridge Amplifiers is to use a pair of final amplifiers whose outputs have opposite phase each other. There are 3 ways to make a pair of power amplifiers have opposing phases: with internal modification, with an audio transformer (phase splitting audio input transformer) and with a simple active phase reversal splitter circuit). This paper will discuss Bridge Amplifiers with simple phase inverting circuits. A pair of audio power amplifiers using two TDA2050 chips which are operated at ± 19 Volt supply voltage. The phase inverting circuit using IC TL072. Sinusoidal signal with an amplitude of 200 mVp and a frequency of 1 KHz is used as an input signal. The results to be observed and measured are gain, input, output and bandwidth of the bridged amplifier compared to the usual amplifier
"Kei A Koe, Chair!" – The Norms of Tikanga and the Role of Hui as a Māori Constitutional Tradition
Authors: Stephens Māmari
Published: November 2022

Hui and hui rūnanga, Māori decision-making gatherings, are vital in Māori constitutionalism. Hui demonstrate the practical exercise of tikanga Māori. There is a set of relatively stable Māori legal norms, derived from tikanga Māori, that can be seen at work in such hui-based decision-making. These norms (mana, tapu, whakapapa, whanaungatanga and rangatiratanga) serve to strengthen and demonstrate group processes. They arguably do not establish merely optional guidelines for group behaviour; they can serve to constrain decision-making. A case study set in a hui in a modern Māori urban context serves to demonstrate the exercise of such Māori legal norms in civic decision-making.

Authors: Saromines Chrisley Jade , Canoy, Jr. Sergio
Published: November 2022

Let G be an undirected graph with vertex and edge sets V (G) and E(G), respectively. A hop dominating set S ⊆ V (G) is called an outer-connected hop dominating set if S = V (G) or the subgraph ⟨V (G) \ S⟩ induced by V (G) \ S is connected. The minimum size of an outer-connected hop dominating set is the outer-connected hop domination number γfch(G). A dominating setof size γfch(G) of G is called a γfch-set. In this paper, we investigate the concept and study it for graphs resulting from some binary operations. Specifically, we characterize the outer-connected hop dominating sets in the join, corona and lexicographic products of graphs, and determine bounds of the outer-connected hop domination number of each of these graphs.

ECCLESIASTICAL ARCHITECTURE IN NIGERIA: EXPLORING UNIFYING ELEMENTS IN THE DESIGN OF WORSHIP CENTERS
Authors: Jamila Bala Anita Alaere , Brisibe Warebi Gabriel
Published: November 2022

The primary factor in ecumenism has been the church's unity. The World Council's Central Committee produced an agreed-upon definition of ecumenical in 1951. The word derives from the Greek word for inhabited earth, and it refers to the church and its efforts to spread the Gospel over the world. As a result, ecumenism is linked to the Christian faith's unique unity and mission in the context of the entire globe. In Nigeria, some State Governments have attempted to unify the key denominations of the Christian faith in an attempt to pursue this common mission by literarily bringing them under one roof. In other to achieve that, markers, and features of scared spaces for each of these denominations have to be identified and combined where possible. This paper explores how elements have been unified in the design of these Government initiated archetype.
LEVEL OF STRESS, SELF-ADJUSTMENT, AND QUALITY OF LIFE FOR SINGLE FATHER
Authors: Saputra Moh. Fahmi , Krisnatuti Diah
Published: November 2022

Single parents are associated with unique adjustment needs because of the multiple roles they accept, so heavy burdens, especially for single fathers, can trigger stress and affect their quality of life. This study aims to analyze the effect of stress levels and adjustment on the quality of life of single fathers. This study involved 60 single fathers living in villages and cities distributed throughout Indonesia using a purposive sampling technique with data collected through an online questionnaire google form. Processing data using Microsoft Excel and SPSS version 25 with descriptive analysis, different independent sample t-tests, Kendalls tau-b and Pearson correlation test, and multiple linear regression test. The results showed that the variables of stress level and quality of life were in the medium category, while the adjustment variable was in the low category. The relationship test results showed a significant relationship between stress levels (negative), adjustment (positive), and quality of life. The regression test results showed a significant negative effect of stress levels and a significant positive self-adjustment on the quality of life of single fathers, meaning that the lower the stress level and the better the adjustment, the higher the quality of life of single fathers. The single father feels that with his current conditions, his quality of life can still be controlled, although sometimes he has some obstacles. In the future, it is hoped that this can be done regarding other variables that affect the quality of life, as well as exploring the comparison of single fathers and single mothers.

Published: November 2022

The marriage that occurs at a child's age has a negative impact on the development of children and their families. Child marriage is not only caused by external factors but also by internal factors, such as the desire of teenagers can encourage child marriage. This study aimed to determine the effect of economic pressure and parent-adolescent interactions on adolescent motivation to marry early. This study uses a cross-sectional study design with analysis using Microsoft Excel and SPSS 25 for Windows. The number of research samples, as many as 165 adolescents in Jabodetabek obtained by voluntary sampling by distributing online questionnaires. The research instrument consisted of an objective economic pressure instrument, a subjective economic pressure instrument, a parent acceptance-rejection questionnaire instrument, and an early marriage instrument. The correlation analysis showed that subjective economic pressure positively correlates with early marriage motivation. A mother's education has a significant negative correlation with early marriage motivation. The regression analysis showed that subjective economic and parent-adolescent interaction on the dimensions of violence and psychological control significantly positively affects early marriage motivation. Parents are expected to increase positive interactions by reducing violence and psychological control on children to reduce the motivation for early marriage.

One aspect of cultural diversity is traditional food. Traditional food serves as a means of expressing thanks, performing cultural rituals, building kinship as well as being a source of nutrition. West Kalimantan is one of the multi-ethnic provinces in Indonesia, hence it offers a wide range of traditional foods. The existence of traditional food is threatened to be shifted or replaced by the presence of ready-to-eat food, which is intensively promoted in various media, with the main target being the young age group. This study aimed to determine student’s preferences in Pontianak towards traditional food in West Kalimantan and compare its nutritional composition with ready-to-eat food. This research was conducted using a survey to 150 respondents using online questionnaire. Data were analyzed by the Chi-Square program. The three types of traditional foods that respondents liked the most were tested for their nutritional composition and compared with the nutritional composition of ready-to-eat foods like chicken nugget, hamburger, and fried chicken. The results showed that students in Pontianak had a high preference (90.7%) for traditional West Kalimantan food. West Kalimantan's most preferred traditional foods were kerupuk basah (n=51), bubur pedas (n=49), and ikan asam pedas (n=25). The results showed a relationship between student preferences for food knowledge, nutritional information, taste, and appearance of traditional West Kalimantan foods. The nutritional composition test showed that, in general, traditional foods have higher water content and lower fat content than ready-to-eat food.

Wheat flour is the main ingredient in bread processing. Wheat flour manufacturers produce quality wheat flour suitable for bread in term of its chemical composition and rheological properties. This study compared four types of wheat flours (premium high protein, high protein, economic high protein, and medium protein) produced by PT XYZ (namely GC, GE, KR and BS) with wheat flours produced by other manufacturers (TTK1 to TTK8) in the making of sweet bread. Chemical composition (moisture, ash, protein and gluten), Farinograph profile and sensory quality of the resulting sweet bread were compared. The quality of GC flour had a high moisture and lower protein content than wheat flours in the same class (TTK1, TTK2). This affected the rheological characteristics, i.e a low development time and stability, as well as a high mixing tolerance index (MTI). The KR flour had a higher ash content than other flours in the same class (TTK5, TTK6), while BS flour had a higher moisture content than TTK7 and TTK8. The moisture content of wheat flour had negative correlations on sweet bread taste, while the ash had negative correlations on aroma, crumb, and taste. The protein and gluten of wheat flour affected its rheological characteristics, hence contributed to volume, crumb and softness of sweet bread.

A Mini-Review of the BAPM Framework for Practice – Perinatal Management of Extreme Preterm Birth before 27 Weeks of Gestation
Authors: R. O'Sullivan Joanna , Crowley Nicola
Published: November 2022

The recent publication of a new framework for practice from the British Association of Perinatal Medicine has altered the management of babies born in the UK at the threshold of viability. A risk stratification is used to determine which infants will receive active management, and which receive palliative management. This is achieved through a combination of assessment of risk factors and discussion with parents. The most notable feature of the new framework is the recommendation to consider babies of 22 weeks gestation for active care. This has been the subject of much discussion amongst neonatal and obstetric teams. The framework also emphasises the importance of early transfer to a maternity unit with a co-located neonatal intensive care unit if active management is pursued. This new guidance has led to a change in the way the management of extreme prematurity is approached, and will continue to impact on neonatal, obstetric, and anaesthetic care.
A Review of the Effectiveness and Safety of Topical Anesthetics in Corneal Abrasions
Authors: B. Shipman Stacia , A. Painter Kelly
Published: November 2022

Corneal abrasions are known to be extremely painful and are a commonly seen eye condition. Topical anesthetic drops used for diagnosis of corneal abrasions provide immediate pain relief for most patients, but their use for outpatient use has been controversial. There is lack of consensus regarding ideal management of pain associated with corneal abrasions, with some physicians prescribing nonsteroidal anti-inflammatory drugs or opioids which both can have serious side-effects and/or abuse potential. In recent years, several studies have been conducted to assess the efficacy and safety of short term topical anesthetic use for the treatment of acute corneal abrasions. For this review, four published randomized controlled trials were identified that focused on the effectiveness and safety of various topical analgesics used in treating corneal abrasions. These showed varying degrees of efficacy depending on the outcomes measured without any significant difference in complication rates. Additionally, we reviewed an observational study that investigated whether routinely sending corneal abrasion patients home with a 24-hour supply of topical tetracaine is safe. They found no increased risk of ED revisits, fluorescein uptake at follow up, or ophthalmology clinic referrals. Larger prospective studies are still required to establish definitive safety, but the current available evidence suggests use of topical anesthetics for simple corneal abrasions is efficacious and safe.
Estructura y composición del bosque de Pinus hartwegii Lindl. en su distribución altitudinal en el Nevado de Toluca

Published: November 2022

Conocer la estructura y composición de un bosque permite entender los atributos dasométricos de los árboles y los procesos ecosistémicos a lo largo de gradientes de vegetación derivados de la altitud. Se analizó la estructura del bosque de Pinus hartwegii en un gradiente de 600 m, en el Nevado de Toluca. Se establecieron conglomerados de 1 ha en cada altitud; se registraron variables dasométricas. La estructura vertical y horizontal se evaluó con la densidad arbórea (DA), área basal (AB) y parámetros e índices estructurales. Estos últimos mostraron que P. hartwegii mantienen su abundancia y dominancia a lo largo del gradiente altitudinal estudiado, principalmente de los 3 700 a 4 000 m, donde forma bosques monoespecíficos. La contribución en la estructura arbórea disminuyó de 100 % a 3 900 y 4 000 m, a 45 % en los 3 500 m. Los parámetros dasométricos indicaron mayor DA en individuos de clases diamétricas de 5-15 cm, fue superior por debajo de los 3 800 m; ello evidenció que la regeneración puede ser más limitada a grandes altitudes, posiblemente debido a una extracción irregular del arbolado. Se concluye, que la composición estructural del bosque de P. hartwegii presenta un cambio importante en su estructura de acuerdo con la altitud, lo que resultaría de la interacción ambiente-sociedad mediante la gestión del uso del suelo asociada a la altitud, que compromete la estructura y función del ecosistema. Se recomienda incorporar la altitud como una variable determinante en planes de manejo para bosques de alta montaña.

Published: November 2022

Las características de copa de un árbol o del dosel en un rodal están influenciadas por la exposición a la luz, la competencia por nutrimentos, la densidad de árboles, la estructura de la vegetación y por la especie. El dosel es un indicador fotosintético determinante en la productividad forestal y pauta en la silvicultura. El objetivo de esta revisión fue documentar de manera general, en una primera versión, el efecto de los procesos fisiológicos en la arquitectura de copa y su importancia para el manejo silvícola de los bosques templados. La dinámica de crecimiento y desarrollo de la copa están en función de la interacción entre los individuos en el rodal, la edad del arbolado, la etapa fenológica, las condiciones climáticas, la humedad y la temperatura; además de las características topográficas y de suelo. Los valores del Índice de Área Foliar, la productividad primaria neta aérea, las tasas de crecimiento e incremento y la respuesta en el rendimiento expresado en volumen, biomasa o carbono son parámetros indirectos que miden la eficiencia de los procesos fisiológicos en las especies. Conocer y comprenderlos en la arquitectura y dinámica de copa contribuyen a planear y ejecutar actividades silvícolas acordes a las necesidades particulares de cada especie o rodal. La aplicación de estos conocimientos se enfoca en el mejoramiento de las tasas de crecimiento e incremento de los bosques.

Published: November 2022

En este estudio, se modelan y analizan los eventos de incendios forestales registrados en los últimos 19 años por el satélite de observación MODIS en el estado de Oaxaca; para ello, se utilizó un modelo Poisson jerárquico bayesiano, el cual modela el número de incendios forestales espacial y temporalmente, así como la interacción de ambos. De acuerdo con los resultados, algunas variables ambientales como la temperatura del trimestre más seco, la velocidad media del viento, el índice de vegetación mejorado y la ocurrencia del fenómeno El Niño-Oscilación del Sur, explican parte de la variabilidad espacio-temporal observada. Derivado del análisis, se identificaron dos grupos espaciales: el primero cubre desde la Sierra Juárez hasta el Istmo de Tehuantepec, y el segundo abarca la Sierra Sur. Adicionalmente, el término temporal sugiere que el número de eventos se ha incrementado en aproximadamente 42.2 % en las últimas dos décadas. Los resultados indican que los incendios forestales se han incrementado tanto espacial como temporalmente. Estos hallazgos son señales de alarma, dado que si la tendencia continua, en las siguientes décadas cientos de nuevas hectáreas de bosque y su biodiversidad serán amenazadas a causa de los regímenes de fuego alterados, que también afectará las actividades económicas y la salud de los habitantes de las áreas rurales y urbanas del estado. La información generada puede ser un punto de partida en el diseño de programas más eficientes para mitigar el impacto de los incendios forestales en Oaxaca
