Иван Бунин – медиатор непримиримых сторон
Authors: Смирнов Иван
Published: February 2022

В статье автор рассматривает творческую деятельность классика русской литературы И. Бунина с точки зрения медиации. Вопреки устоявшемуся мнению о том, что писатель в творчестве сосредоточился только на двух главных темах – любви и смерти, автор подвергает сомнению категоричные суждения и приводит доводы, согласно которым литературные принципы художника по противостоянию революционным кровопролитиям, следует рассматривать как предтечи медиации. Помыслы писателя, отраженные в его дневниках, поэзии и прозе, пронизаны желанием предотвратить разрушение государства, найти компромисс, сохранить русскую культуру, чистоту языка, а значит, и саму Россию.

Artykuł jest zapisem refleksji wywołanych lekturą książki Grzegorza Ojcewicza Wstęp do filologii śledczej. Wybór tekstów a lat 2008–2020. Szczególną uwagę zwracam w nim na zaproponowaną i zrealizowaną w kolejnych fragmentach monografii pionierską metodę badań Ojcewicza, polegającą na połączeniu w refleksji naukowej kompetencji filologa, historyka literatury i tekstologa z profesjonalizmem i aparatem śledczego. Mistrzowskie wykorzystanie nowej metody badawczej pozwoliło Autorowi wyjaśnić (lub zbliżyć się do wyjaśnienia) owiane tajemnicą historie życia, śmierci „wyklętych” pisarzy rosyjskich, ale także postaci historycznych. Wyjątkowe znaczenie w historii literatury zyskuje z pewnością rozdział poświęcony losom Mariny Cwietajewej, szczególnie ostatnim tygodniom jej życia.

Authors:   Dário Vianna Birolini,   Eduardo Rissi,   Gustavo Souto Rachid Hatun
Published: February 2022

Background: There is a positive association between various types of cancer and diabetes. Duodenopancreatectomy is the treatment of choice for diabetic patients with duodenal tumors. Pancreatic resections may trigger endocrine insufficiency. There is an association between poor glycemic control and lower survival rates. Low carb diets appears to be an effective approach in the treatment of diabetic patients that require pancreatic resections. Case Presentation: We report the case of a type II diabetic diagnosed with resectable duodenum cancer. At the time of diagnosis he was jaundiced and with decompensated diabetes. The patient was submitted to a low carb diet for three weeks and, having improved its physiological and metabolic parameters, we performed a duodenopancreatectomy. The patient evolved without complications, with easy management of postoperative glycemia. Conclusions: Low carb diets can prove to be a powerful, inexpensive, and safe tool to add to our therapeutic arsenal before pancreatic resections.
Análisis y estimación del contenido de carbono en pastizales halófilos de la zona central semi-árida de México

Published: February 2022

Las estimaciones del almacenamiento y liberación de carbono dependen principalmente del tipo de vegetación, del cambio en el uso del suelo, edad de la vegetación y tipo de ecosistema (cerrado o abierto). El carbono captado y almacenado tiene un valor ambiental positivo, mientras que su liberación a la atmósfera por el cambio de uso de suelo acarrea daños ambientales al propiciar el calentamiento atmosférico global. Los pastizales naturales en México ocupan alrededor del 10% del territorio nacional, de los cuales el halófilo ha sido escasamente estudiado en cuanto a su contribución con el ciclo del carbono. Por lo tanto, el objetivo del presente estudio fue estimar el contenido de biomasa aérea y subterránea; así como el carbono contenido en este tipo de vegetación. Se definió un área efectiva a muestrear de 70 ha en pastizales halófilos del estado de Puebla y se propuso el método de cuadrante bajo un diseño de muestreo con parcelas fijas anidadas. El carbono contenido se determinó al tomar muestras en campo y se llevaron al laboratorio para ser secadas a temperatura constante. El contenido de carbono total calculado para pastizales halófilos fue de 1.33 Mg ha‑1, oscilando de 0.55 a 2.6 Mg ha‑1. En cuanto a biomasa, la parte aérea se estimó en 0.49 Mg ha-1, mientras que la parte subterránea fue de 2.34 Mg ha‑1. La biomasa subterránea medida en campo tuvo una alta correlación con el carbono total (r = 0.87), por lo que podría considerarse como una opción viable para la estimación de carbono a partir del modelo de regresión propuesto.

El aprovechamiento de los residuos en los sistemas de producción agrícola, exige el utilizar diferentes abonos orgánicos para encontrar los niveles de aplicación y sus posibles combinaciones que produzcan cultivos de calidad. El objetivo de este estudio fue evaluar los efectos del estiércol bovino (EB) y vermicompost (V) en el suelo, así como el resultado positivo en la producción de sandía. Se aplicó EB y V en el mismo sitio experimental dos ciclos continuos (2013-2014), para EB en los niveles de 0, 40, 60 y 80 Mg ha-1, considerando fertilización química (FQ) para la Comarca Lagunera 120-60-00 y para V 0, 3.0, 6.0 y 9.0 Mg ha-1. Se tomaron muestras de suelo al inicio y al término de cada año a tres profundidades tomando en consideración el área radicular de la planta y el bulbo de humedad 0-15, 15-30 y 30-45 cm, evaluando materia orgánica (MO), pH, conductividad eléctrica (CE) y nitratos (NO3-). En el fruto se evaluaron los sólidos solubles totales (°Bx) y el rendimiento. Los contenidos mayores de MO (3.23% en el 2013) y NO3- (41.4 kg ha-1 en el 2014) se encontraron de 0-15 cm con la interacción de 80 Mg ha-1 de EB y 9.0 Mg ha-1 de V. La CE se incrementó hasta 6.6 dS m-1 de 0-15 cm lo que implicó, después de dos ciclos de aplicación la disminución en el rendimiento hasta 66.1% en los niveles de 80 Mg ha-1 de EB y 3.0 Mg ha-1 de V. En el 2014 se encontró diferencias para el rendimiento y los °Bx. En el 2014, se obtuvo el mayor rendimiento (29.2 Mg ha-1) concluyendo que la fertilización química (FQ) fue superada por la interacción de EB (80 Mg ha-1) con V (6.0 Mg ha-1), para °Bx igual a 8.4 en la interacción de 60 Mg ha-1 de EB con 9.0 Mg ha-1 de vermicompost.
Simulación numérica de la interacción fluido-estructura para predecir la respuesta de aerogeneradores sin palas a vibraciones inducidas por el viento en ciudades compactas
Authors: Andrade-Terán Cristian
Published: February 2022

En este artículo se presenta un análisis de la respuesta fluido-estructura de los aerogeneradores sin palas que funcionan por resonancia aeroelástica inducida, los cuales pueden ser utilizados en ciudades o pueblos pequeños para formar parte de un urbanismo sostenible. En este análisis se llevan a cabo simulaciones numéricas del comportamiento del viento y del efecto denominado vórtices de von Karman que produce al rodear la estructura del aerogenerador utilizando como datos de entrada las velocidades del viento medidas por la Estación Meteorológica Mariscal Sucre en Quito. Las simulaciones CFD determinan la señal de excitación causada por los diferentes flujos de viento existentes. Asimismo, los efectos que estas oscilaciones causan en la estructura se simulan a través de un estudio modal y respuesta armónica a resonancia. Los resultados obtenidos muestran un aumento proporcional en la frecuencia y amplitud del desprendimiento de vórtices al aumento de la velocidad del viento, lo que provoca diferentes señales de excitación que hacen que el aerogenerador oscile con amplitudes entre 6 a 11 cm. Finalmente, las simulaciones transitorias muestran que la presencia de casas y edificios en las cercanías en donde se instala el aerogenerador hacen que la dirección de la calle de vórtices varíe, así como las alteraciones en la frecuencia y amplitud de la excitación.

Published: February 2022

The service sector is often associated with a countries economic's progress, where the more advanced a country, the greater its role in the service sector. Construction service is one of Indonesia's service sectors which has more than one forward and backward linkage value and shows that construction services are a key sector. However, the average growth of Indonesia's construction services exports during 2015-2020 was only 5.47 percent and still has the potential to be increased. Therefore, it is necessary to know the performance, comparative advantage, and competitive advantage of the construction services sector, which in turn needs to be formulated to increase the competitiveness of the sector. By using primary and secondary data, this study was analyzed using descriptive analysis, Export Product Dynamic (EPD), and Structural Equation Model (SEM). The results of the analysis show that the Indonesian construction services sector still has the opportunity to be developed as seen from the occurrence of excess demand, which indicates that the Indonesian construction market has not been fully exploited. The potential for developing exports of construction services with partner countries can be carried out by Indonesia with Australia, New Zealand, Japan, China, Korea, and several countries in Southeast Asia. The competitiveness of Indonesia's construction services sector is strongly affected by aspects of opportunity, regulation, and demand from partner countries. Therefore, several strategies that need to be carried out by Indonesia to increase the competitiveness of the construction services sector are determining priority partner countries, creating conducive conditions for political, security, economic, and business climate, strengthening and collaboration with Indonesian certification agency with the world of education, as well as strengthening business actors engaged in the service sector to be able to compete with competitors.

The presence of fungi in nature is very abundant, but at this time it is still necessary to know and explore the various types that are able to live in various places. Fungi can live in plant tissue, known as endophytic fungi, and can also live on the leaf surface of a plant. Avicennia marina lives on the coast and is used to reduce abrasion, besides being able to live in tidal habitats and high salinity levels. This is supported by the plant's physiology and the help of its microbial symbionts, therefore it is necessary to explore fungi, especially fungi that are able to symbionting with these plants because they are thought to be resistant to high levels of salinity. The purpose of this study was to determine the types of molds that have been isolated and are able to live in the tissue and leaf surface of A. marina. Characterization method was reviewed through macroscopic and microscopic morphology using a microscope and compared with literature from various sources. The characterization results of the 12 isolates obtained several genera, including Trichoderma, Aspergillus, Penicillium, Curvularia, Paecilomyces, Talaromyces, Syncephalastrum, and 1 unidentified isolate. These isolates need to be continued with further research to see their ability to produce metabolites and so on.

Published: February 2022

Gyrinops versteegii (Gilg) Domke is an agarwood-producing plant originating from Eastern Indonesia. Leaves have antioxidant and anticancer activity due to their secondary metabolites. However, secondary metabolites are strongly influenced by the environment. This study aims to compare the terpenoid, phenolic, and flavonoid profiles of agarwood leaves grown in three locations, namely Bogor, Mataram, and Sambas using Thin Layer Chromatography (TLC), in order to obtain the most potential agarwood G. versteegii for further development as herbal medicine. Agarwood leaf powder was extracted using Soxhlet with 80% methanol as solvent, followed by liquid-liquid fractionation using chloroform and aquadest. The crude extract and the obtained fraction were subjected to metabolite profiling using TLC. Racing data factors from TLC were analyzed using hierarchical cluster analysis (HCA). The results showed that the Mataram sample produced higher yields for both extracts and fractions. TLC detected that the chloroform fraction contained more terpenoids, followed by phenolics and flavonoids, while the aqueous fraction contained the same number of positive bands for terpenoids and phenolics. In terms of origin, the Bogor sample showed six terpenoid positive bands higher than the other samples. A similar pattern was observed in the phenolics, while the flavonoids were the same for all samples. HCA resulted in Mataram being clustered separately from the Bogor and Sambas samples. Agarwood leaves from Mataram cannot be used to replace agarwood leaves from Bogor and Sambas as herbal ingredients.

Published: February 2022

Findings of blood at the crime scene (TKP) can provide important information in criminal cases such as homicide. Blood findings at crime scenes are usually blood spots or traces of blood that can be found on various substrates. This study aims to determine the type of wall substrate and environmental conditions that have the ability to preserve blood better, prove by success rate in identifying blood type in ABO system until 336 hour of exposure. In this study, blood samples were exposed to three variations of wall substrates, namely plastered walls, plastered and painted walls, plastered and oil-painted walls; and in two different environmental conditions (indoor and outdoor). The method used to identify blood type in this study was absorption elution. First, blood samples from substrate was transferred to a gauze by NaCl 0,98%. Then a confirmation test was carried out to ensure that the gauze sample contains a blood sample. Positive results of the confirmation test were indicated by a change in the color of the sample to bluish green when it is dripped with H2O2 and Leuco Malachite Green (LMG). The positive sample was then dripped with antiserum to determine the blood type. The success of identification of blood groups was indicated by the agglutination in the samples that were dripped with antisera A, because the blood samples used in this study are group A. The results showed that the success rate of blood group identification on the three types of substrates in the indoor environment for 336 hours was 100%. Meanwhile, in the outdoor environment, only blood samples exposed to plastered wall substrate and wall paint for 264 hours could be identified for their blood type. It can be concluded that the three types of wall substrates have the same ability to preserve blood samples for up to 336 hours of exposure, but the environmental conditions that give the best percentage of successful blood group identification were in indoor conditions. For further research is recommended to focus on external environmental factors that have the most influence on the success of blood group identification in dried blood samples.

Published: February 2022

The marine environment has a significant role in maintaining the balance of gas exchange in the air, especially between oxygen and carbon dioxide. The potential of the marine environment for gas exchange is supported by the existence of marine ecosystems such as seagrass ecosystems. This is in accordance with the blue carbon concept which plays a role in environmental mitigation in reducing carbon through the coastal environment. Therefore, the purpose of this study was to assess the potential carbon content of the diversity of seagrass species at three locations of seagrass beds in the coastal waters of Central Lombok. The research method uses the line transect method and the ashing method. Seagrass vegetation data were analyzed using community structure analysis (diversity, uniformity and dominance). In addition, analysis of seagrass biomass and carbon content of seagrass was carried out. Furthermore, the regression analysis between seagrass density as the independent variable (X) and the carbon content of seagrass species as the dependent variable (Y). The results of the study found 8 species of seagrass found in the waters of Central Lombok with moderate diversity ranging from 1.59-1.77. The value of seagrass biomass in the waters of Central Lombok is dominated by the bottom substrate with a value of 3.38ÃÂ±1.58 gbk.m-2 while the upper substrate with a value of 1.69ÃÂ±0.98 gbk.m-2. The carbon value of seagrass in Central Lombok waters is dominated by the bottom of the substrate with a value of 1.39ÃÂ±0.22 tonC/Ha while the upper substrate is 0.72ÃÂ±0.13 tonC/Ha. Meanwhile, the results of the calculation of the Pearson's correlation (r) between the density of each type of seagrass as an independent variable (X) and the carbon content of each type of seagrass as the dependent variable (Y) shows the equation y = 10,608x + 70,155 with a correlation coefficient of 0.64 which belongs to the category medium and the coefficient of determination (r2) is 0.41. The conclusion of this study is that there is no significant relationship between the density of each type of seagrass and the carbon of each type of seagrass as indicated by the value of Fcount (4.17) < Ftable (6.60) with a value of =0.05 so that H0 is accepted and Ha is rejected.

Published: February 2022

Genome editing technique is one of the methods for studying the expression of gene, eliminating unfavorable traits or phenotypes and generating the new characters of species. The pRGEB32 plasmid is one of the vectors that used in genome editing with carrying the Cas9 gene, restriction site of sgRNA (single guide RNA) and specific promoters that can be expressed in plants. The first step in the genome editing process is inserting pRGEB32 into Escherichia coli for propagation. The large size of the plasmid molecule becomes a challenge to determine the right method in the transformation process. This study aims to determine the temperature and time of heat shock transformation of plasmid pRGEB32 into E. coli. The transformation of pRGEB32 into plasmids was carried out with variations in temperature and time, 42Ã¢âÆ (30 seconds and 60 seconds) and 55Ã¢âÆ (30 seconds and 60 seconds). The results showed that a heat shock temperature of 55Ã¢âÆ with a time of 60 seconds was the best temperature for the transformation of pRGEB32 into E. coli. This optimization of heat shock condition will increase the transformation efficiency, which is in the range of 3322-10.989 cfu/ÃÂµg.ÃÂ

The research purposed to increase the durability of Medang wood (Chinnamomum javanicum) with the preservation methods using fumigation and evaluated againstÃÂ Schizophyllum communeÃÂ Fries fungi. Medang wood from gubal area was achieved from Kubu Raya Regency and made into a sample for preservation treatment measuring 5 cm x 2 cm x 2 cm. The wood preservation methods used fumigation. The fumigation process used an oven and time of fumigation consisting of 12 hours, 24 hours, and 36 hours. The temperature process was 80oC. After preservation, the wood was tested against Schizophyllum communeÃÂ Fries based on SNI 7207-2014. The result of preservation showed that the fumigation process changed the color of Medang wood. The color changed from white pale into brown (12 hours fumigation), dark brown (24 hours fumigation), and very dark brown (36 hours fumigation). The weight loss of Medang wood after 12 weeks attacked byÃÂ Schizophyllum communeÃÂ Fries fungi was range between 2.45% - 3.44%. The weight loss of Medang wood on treatment 12 hours fumigation was 3.44%, on treatment 24 hours was 3.34% and on the treatment of 36 hours was 2.45%. After the fumigation methods, the durability of Medang wood increased into II class. The compound from smoke during the fumigation process, which functions as antifungi, was phenol. The optimum treatment to increase the durability of Medang wood was fumigation for 36 hours with a temperature of 80oC.

Mosquitoes often being the vector of some diseases, such as dengue hemorrhagic fever. To prevent these diseases vectored by mosquitoes, we could use mosquito repellent. But based on some research, these mosquito repellents on the market contain some dangerous chemicals, for example, Dichlorvos, Porpoxure, and synthetic pyrethroid. These kinds of chemicals can cause some side effects that are not good for health, ranging from headaches, nausea, to cancer and organ dysfunction. Therefore, it is necessary to have a mosquito repellent that is safer for health with minimal side effects. This research is an experimental type of research that aimed to determine the effectiveness of anti-mosquito in the form of an aromatherapy candle made of the beehive with the consistency of pala pulp extract and langsat seed extract. Pala pulp extract and langsat seed extract were obtained from the maceration method and then processed by Rotary Evaporator.ÃÂ  The concentrations used are Pala pulp extract: langsat seed extract. I: 0,5gr:0,25gr, II: 5gr:2,5gr. Both of the concentrations will be blend into 200gr of solid candle that will be melt. A test was made on some adult mosquitoes. Mosquitoes are being bred. The mosquitoes were placed on a cage that had been build by the researchers first. The measurement scale on this research is the mortality rate of the mosquitoes counted from the second we light up the anti-mosquito aromatherapy candle. There are two types of data analysis on this research, includes the anti-mosquito test and organoleptic test. The first concentration test's result shows that there is a very minimal effect on the mosquitoes. when the test was run, there were five adult mosquitoes inside the cage, an observation was done for 10 minutes counted from the time the candle was lit up. At the first 2 minutes 10 seconds, there is 1 mosquito that died, and the rest of the time for 10 minutes there was no other ÃÂ mosquito died. The second concentration test's result shows a really big impact on the mortality rate of the mosquito. There were seven adult mosquitoes inside the cage when the test was run. And for 10 minutes, 6 mosquitos died. This means that the second concentration was the most effective amount of the concentration to apply on the candle. Hopefully, the result of this research could be useful for society in terms of environment-friendly anti- mosquito usage.

The purpose of this study was to analyze the effectiveness of soaking eggs using a solution of Moringa leaves for 24 hours on the internal quality of broiler eggs. Soaking aims to provide a layer on the pores of the egg shell so that it can keep the eggs from microbes and inhibit the release of gas from the egg. This type of research is experimental with Completely Randomized Design (CRD). The number of eggs used is 1000 eggs. The egg samples used are 420 eggs. The eggs used are in good condition, namely brown eggs, clean, intact, not cracked, texture smooth and oval in shape. The randomization method used random sampling in the form of a lottery system. Each of the 420 eggs is labeled. The eggs that were taken at random were divided into 4 treatment groups. Each treatment group consisted of 5 replications. Therefore, 20 treatment replications were obtained. Measurement of storage time and internal quality of eggs will be tested for 21 days. This is done to determine the level of egg resistance accurately, because the embryonic development period of the egg occurs for 21 days. Egg parameter measurements were carried out every day, at 08.00 WITA. Egg quality parameters were taken every 7 days. Egg quality parameters analyzed were egg white index, egg yolk index, and egg weight loss. All measurement data were analyzed by analysis of variance (ANOVA). If the results of the analysis have an effect, the Tukey test is continued with 95% confidence (ÃÂ±> 0.05). The data that has been analyzed explains that chicken eggs that get soaked in a solution of Moringa leaves have a higher index of egg yolk and egg white than eggs that are not soaked in a solution of Moringa leaves. The most optimal concentrations in maintaining the egg yolk and egg white index are 30% and 45% Therefore, soaking eggs with Moringa leaves serves to maintain the internal quality of eggs seen from the yolk index and egg white index.

The purpose of this study is to see how adding the amino acid lysine to commercial feed affects the amount of EPA and DHA in catfish (Pangasius sp.) flesh. This study is an experimental study with a totally randomized design that includes four treatments and five replications. P0 (100% commercial feed + 1.2 percent amino acid lysine), P2 (100% commercial feed + 2.2 percent amino acid lysine), and P3 (100% commercial feed + 3.2 percent amino acid lysine) were the treatments. The parameters observed were EPA and DHA in catfish meat. Data analysis used ANOVA and continued with the DUNCAN test (p 0.05). The results showed that the addition of the amino acid lysine to commercial feed for 30 days of maintenance was able to increase the EPA and DHA content in catfish meat. The highest EPA content was obtained by treatment P1 (1.2% amino acid lysine), which was 0.597%, while the highest DHA content was obtained by treatment P2 (2.2% amino acid lysine), which was 0.747%. Our findings demonstrate that adding the amino acid lysine to the diet can result in nutrient-rich catfish flesh. However, studies on the influence of lysine amino acid on the growth rate, survival rate, and cholesterol ratio in catfish flesh are predicted to enhance the productivity of this very nutritious fish.

Musa paradisiaca cv Haji is a local banana of Lombok that has a longer shelf life. The determination of the haji banana genome still uses a scoring method based on morphological character. Clarification of ploidy levels and genome types can be done using chromosome analysis. The initial information needed to perform the karyotype analysis is identifying the cleavage time of M. paradisiaca cv Haji. Banana Haji on the island of Lombok has a different local name, so morphological identification of the haji banana accession is required. Morphological observations were conducted on three accessions of Haji bananas from different cultivation sites. Identification of the time of mitosis cleavage is made by the Squash method. The results showed a uniform synapomorphic character in the haji banana accession. The characters include the aspects of pseudostem (normal), shiny pseudostem, imbricate young bractea (young bractea slightly stacked), red inner bractea, straight ovary, and no pigmentation on the stylus. The autapomorphic character of Haji banana accession in this study included inside the pseudostem of the red-green, the position of horizontal fruit bunches, a fair amount of wax on the surface of the lower leaf, and the petiole of the lower leaf in pink. There are morphological character differences in Haji cultivar accession on pseudostem color and tepal color pigmentation. The time of mitosis division in Haji bananas, especially the prophase stage - metaphase from 06.38 - 07.38 Wita. The results obtained in this study can be used as a foundation to conduct karyotype analysis of Musa paradisisaca cv Haji.ÃÂ
