Thí nghiệm được tiến hành nhằm khảo sát đặc điểm sinh trưởng và giải phẫu của cỏ Lông tây (Brachiaria mutica). Thí nghiệm được bố trí hoàn toàn ngẫu nhiên với 7 nghiệm thức: T1 (10 ngày), T2 (15 ngày), T3 (20 ngày), T4 (30 ngày), T5 (40 ngày), T6 (50 ngày) và T7 (60 ngày). Sinh trưởng và phát triển của cỏ Lông tây chia làm ba giai đoạn: (1) Giai đoạn sinh chồi từ T1 đến T3, trong giai đoạn này cây tập trung cho tái sinh chồi; (2) Giai đoạn kéo dài lóng và tăng diện tích lá từ T4 đến T6, là giai đoạn cây phát triển mạnh cả về chiều cao, đường kính thân và dài rộng lá; và (3) Giai đoạn sinh trưởng chậm từ T7 (60 ngày) trở về sau, tại giai đoạn này diện tích lá ngưng tăng trưởng. Kết quả khảo sát vi phẫu cho thấy ở nghiệm thức T7 số lượng tế bào có vách tẩm thêm lignin (chất tạo chất gỗ) nhiều nhất. Cấu trúc các loại mô tạo chất xơ như mô dầy, mô cứng của thân cỏ Lông tây ở nghiệm thức T2 và T4 tương đương nhau và thấp hơn so với nghiệm thức T7. Hình ảnh giải phẫu của lá ở nghiệm thức T7 cũng cho thấy số lượng mô cứng cao hơn so với nghiệm thức T2 và T4 làm cho diện tích mô có khả năng đồng hóa/quang hợp giảm. Sự kết hợp hài hoà giữa năng suất và chất lượng của cỏ Lông tây cần được xem xét trong giai đoạn từ 30 đến 60 ngày sau khi cắt.

El proyecto arquitectónico de la filosofía crítica de Kant como reforma a la filosofía
Authors: Caballero López Daniel
Published: December 2021

El presente artículo ofrece una interpretación de la totalidad de la filosofía kantiana como reforma al concepto de filosofía de acuerdo con la naturaleza metafísica y moral de la razón. Para ello se articulan los elementos que sirven a la reforma, a saber, la comprensión de la filosofía bajo el concepto escolástico y bajo el cósmico, este último desprendido de la teleología racional expresada en la consideración histórica de la filosofía. Después, se construye la interpretación de la metodología arquitectónica que utiliza la reforma, primero demostrando que la pregunta crítica sobre los juicios sintéticos a priori sirve para determinar los conocimientos posibles; posteriormente, argumentando que la pregunta se subsume a los intereses racionales de los seres humanos para vincular los conocimientos con el fin de la razón, lo cual corresponde a la estructuración de la filosofía según la Sabiduría a la que tiende. Por último, se propone cuál es la labor que cada Crítica tiene dentro de todo el proyecto de reforma. La interpretación, por tanto, recupera las intenciones eminentemente metafísicas y morales de la empresa kantiana, permitiendo abordarla en su conjunto.
ANÁLISIS CUANTITATIVO DE LOS INCENDIOS OCURRIDOS ENTRE 2006 Y 2017 EN LA SUB-CUENCA DEL RÍO ITACAIUNAS, MARABA, PARA, BRASIL

Published: December 2021

La inflamabilidad de los bosques de la Amazonia brasileña, especialmente en las regiones sur y sudeste del estado de Pará, es una amenaza para el ecosistema y para las poblaciones y comunidades tradicionales. Por lo tanto, el objetivo de este estudio fue el estudio de los datos sobre los incendios ocurridos en la subcuenca del río Itacaiunas entre 2006 y 2017. El método utilizado fue deductivo, con cobertura cuantitativa y cualitativa, y se aplicó la naturaleza. Los datos analizados se obtuvieron de sitios de libre acceso relacionados con el foco de estos estudios, como el Ministerio de Medio Ambiente, el Instituto Nacional de Investigaciones Espaciales, el Programa de Monitoreo de la Selva Amazónica Brasileña y la Base de Datos de Quemados. El análisis de los datos obtenidos para el período analizado indicó que en la subcuenca del río Itacaiunas, el municipio de Marabá, presentaba altos índices (n = 4.122; 41.4%), Eldorado dos carajás presentaba un índice más bajo (n = 1.583; 15.9%). En el caso de Marabá, la creciente extracción de madera es una de las razones de esta cantidad de quema. El índice más bajo de todos se registró en Sapucaia (n = 128; 1.3%), que tiene como economía la extracción de vegetales, la caza y la pesca. Por lo tanto, los incendios en estas regiones están asociados a los aspectos económicos desarrollados por ellas, por lo que necesitan con mayor frecuencia nueva información de nuevos estudios académicos, siempre basados en el contenido comparativo de investigaciones anteriores para verificar su aligeramiento o reducción.
EVALUACIÓN SISTEMÁTICA DE LA TECNOLOGÍA DE TRATAMIENTO FISICOQUÍMICO A BASE DE ZEOLITAS DE LAS AGUAS RESIDUALES GENERADAS POR EL RASTRO TIF DE VILLAHERMOSA TABASCO
Authors: Cárdenas Garza Zonia , Rocha Rios Jose
Published: December 2021

En México, los proyectos de tratamiento de aguas residuales provenientes de rastros municipales son de gran interés, ya que permiten reutilizar el agua contaminada en sus propias instalaciones y garantizar su correcta reincorporación al drenaje y/o alcantarillado público, también contribuyen a reducir la huella hídrica en el país. Para que estos proyectos sean exitosos es necesario evaluar, desde un enfoque sustentable, todas las opciones disponibles, y así seleccionar la tecnología más adecuada. Este trabajo presenta una evaluación sistemática para identificar si una tecnología fisicoquímica a base de zeolitas, seleccionada por el constructor, es la mejor opción para el tratamiento de aguas residuales del nuevo rastro Tipo Inspección Federal (TIF) de la ciudad de Villahermosa Tabasco, o por el contrario, si una tecnología biológica propuesta por nosotros sería más adecuada. Para el desarrollo del estudio se consideraron las características del agua residual del rastro y la normatividad aplicable, que en este caso es la Norma Oficial Mexicana (NOM) de la Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), la NOM-002-SEMARNAT-1996, que establece los límites máximos permisibles para contaminantes de las descargas de aguas residuales a los sistemas de alcantarillado urbano o municipal. La comparación entre ambas tecnologías se desarrolló mediante la aplicación de la metodología descrita en el libro “Selección de tecnologías para el tratamiento de aguas residuales municipales”, de los autores Noyola et al. (2013). Nuestros resultados indican que la propuesta biológica sería más sustentable que la opción fisicoquímica basada en zeolitas.

Published: December 2021

The article discusses issues associated with removing explosive from artillery shells, with particular focus on hydrofluidic washing out technology. A multi-well hydraulic test site and highpressure work equipment, as well as testing methodology used in field tests, which allow washing out of explosive materials from such ordnance using a high-pressure water jet, are presented. The studies on the hydro-jet process of washing out trinitrotoluene (TNT) were carried out on high-explosive (HE) shells with calibres of 85, 100, 122 and 125 mm. As a result of the tests, the variability of the TNT washing out mechanism, dependent on hydro- and thermodynamic conditions of this process, which in turn are dependent mainly on the pressure of the water jet, was proven. Comparison of the results of these experiments with the results of previous studies on the washing out of a substitute material which duplicated the mechanical properties, resulted in the determination of an appropriate factor correcting the potential effectiveness of such a process, which allows conducting safe simulation tests under laboratory conditions. In turn, evaluation of the morphology and geometrical structure of washed out TNT, as well as its thermal stability and detonation velocity made it possible to suggest possible applications of the washed out explosive material, especially as a component of mining explosive materials.

Abstract: Now a days we are living in this world where everything is automated and linked online. Internet are the things discover and it is used all over a world very beneficially.in human body face is the crucial factor for identifying each person. It can be identified by using different method like biometric for taking attendance. But in this method many more time are required to take attendance and also people are in contact with each other while marking their attendance in this pandemic situation we are introducing new technology student attendance system using face reorganization. Generally in a classroom the attendance was taken manually at ending or beginning of the class. The problem is that they required a lot of time to be taken and some manual and paper work will make a chance of mistake. To overcome from this problem we are introducing face recognition base attendance system. It is used in many application for identification of human face in a digital image or live video stream video. The proposed system make used of Haar classifier, KNN, CNN, SVM and global filters. After this recognition attendance report will be generated in excel format. The overall accuracy and complexity are calculated after testing this system it is cost efficient and need less installation time. Keywords: Face recognitions, Face detection, Haar classifier, CNN, KNN, SVM, LBPH, Automatic Attendances and image processing.
Effective Extension Sustainability in the face of COVID-19 Pandemic in Smallholder Agricultural Markets
Authors: Siankwilimba Enock
Published: December 2021

Abstract: The effects of COVID-19 have tested and crushed the earlier achievement in sustaining the agricultural and extension delivery system globally. COVID-19 has pressed a reset panel on the extension services more especially among the smallholder farmers who are already underprivileged. Specifically, this review paper aims to analyse studies on the sustainability of agricultural extension delivery systems in face of the COVID-19 crisis. The various theories and factors advanced in discussing sustainable agricultural extension delivery systems, and how they contribute to improved production and productivity to end poverty have been addressed. The COVID-19 mitigation strategies and their effect on agricultural extension sustainability have been laid bare. No single sustainability theory can explain how COVID-19 has disrupted the extension delivery systems. The service providers and farmers have had their effects differently, and all players have followed mitigation to the best of their knowledge. Extension delivery has undergone numerous modifications over the years to better meet the demands of farmers and the changing nature of the markets in which they operate. In order to provide effective service delivery and outcomes to farmers, collective involvement of various stakeholders is necessary since no single player can achieve effective extension sustainability alone due to the diverse nature of the challenges, which are mainly influenced by factors such as geographical location, poverty, and social status among others. Therefore, appropriate approaches should be selected based on the needs of farmers and the market dynamics of a specific economic orientation in a given area. We conclude that effective and sustainable extension delivery systems require many combined theories, support functions, formal and informal rules, and regulations involving all extension-based stakeholders. Keywords: Sustainability, COVID-19, smallholder farmers, agricultural market systems, extension services

Published: December 2021

Un total de 27 variables de manejo (antes, durante y después del sacrificio) en 394 bovinos fueron analizadas y utilizadas para determinar su asociación y valor explicativo con la presencia de carne DFD (Dark, Firm, Dry, por sus siglas en inglés), mediante las razones de probabilidad en un modelo de regresión logística múltiple. El estudio se realizó de noviembre de 2016 a agosto de 2017 en un rastro Tipo Inspección Federal localizado en el noreste de México. La presencia de carne DFD fue del 13.45 %. Se realizó un contraste entre clases para los factores evaluados mediante t Student y Ji cuadrada en función de la naturaleza de la variable como criterio de inclusión en la modelación logística. Diez de las variables mostraron significación estadística (P<0.05) en estas pruebas, pero solo cuatro de ellas presentaron valor explicativo en el modelo logístico múltiple final (P<0.01), las cuales fueron: el tiempo de espera previo a la muerte, un mal insensibilizado, el espesor de la grasa subcutánea y diferencial de pH de la canal establecido con 24 h de diferencia. Las dos primeras aumentaron la posibilidad en la presencia de carne DFD, por el contrario, el espesor de grasa y el diferencial de pH fueron inversamente proporcionales. Las cuatro variables incluidas en el modelo final estuvieron presentes en diferentes etapas y son de naturaleza distinta. Por esta razón, para prevenir de manera efectiva este problema se necesita una evaluación multicausal en todo el proceso de matanza.

Published: December 2021

Históricamente, la región Frailesca ha sido una de las principales zonas ganaderas del estado de Chiapas, por lo que se puede intuir que la estructura actual de su sistema lechero es una buena aproximación de la del estado. Este trabajo tuvo como objetivo la caracterización y análisis de las unidades de producción que forman parte del sistema lechero de la región Frailesca con la intención de describir su estructura en cuanto a tamaño y tipo de unidades de producción. Para tal fin se utilizaron parámetros de producción, de costos de producción e indicadores de rentabilidad. Se determinaron las características principales de las unidades de producción en cuanto a su tamaño y condiciones de operación por localidad de pertenencia, a fin de construir una tipología de productores y de realizar un contraste por localidad. Se encontró que la estructura productiva de la región tiene como base unidades de pequeña escala que constituyen alrededor del 76.7 % del total de las unidades de la muestra, mientras que los medianos productores representan un 14.6 % del total y los grandes únicamente el 8.7 %. Entre estos tipos de productores existe una diferencia significativa en cuanto al tamaño del hato productivo, rendimiento, costos y rentabilidad. En síntesis, la estructura del sistema productivo de la región Frailesca, como otros sistemas de lechería tropical en el país, está constituida por unidades de producción de baja escala con características de unidades familiares con uso intensivo de mano de obra, bajo nivel tecnológico y altos costos de suplementación.

Published: December 2021

In this study, it was aimed to determine of P. multocida, M. haemolytica, H. somni and M. bovis in macroscopically healthy cattle lungs by PCR. The study was carried out on 82 macroscopically healthy cattle lung. DNA extraction was performed to the lung samples. PCR was then performed using all specific primers. By molecular evaluation, positive results  were achieved for  P. multocida,  M. haemolytica,  H. somni and  M. bovis in 4 (4.8 %), 4 (4.8 %), 6 (7.3 %) and 3 (3.6 %) of the samples, respectively. Mix infections were detected in five samples. Of the samples, two were positive for both P. multocida and M. haemolytica, two were positive for both M. haemolytica and H. somni and one was positive for both P. multocida and H. somni. However, a positive sample, which carried all of pathogens, was not detected. In conclusion, P. multocida, M. haemolytica, H. somni and M. bovis are the important opportunistic pathogens of respiratory tract in cattle and these pathogens have a major role during infections. But multifactorial nature of bovine respiratory disease and immune system affected the formation of the disease. Hence, firstly cattle’s immunity should be strengthened and other conditions should be kept under control.

Con el objetivo de definir el panel de polimorfismos de nucleótido simple (SNP) para pruebas de paternidad en bovinos, se analizaron los genotipos en tres razas (número de SNP evaluados e individuos muestreados): Hereford (HER; 202; 1317), Brangus (BRA; 217; 3431) y Limousin (LIM; 151; 8205). Dentro de raza, se descartó los SNP con porcentaje de individuos genotipados (PIG) menor a 90 %, con desequilibrio Hardy Weinberg (HW; P<0.05), con frecuencia de alelo menor de 0.10 o menos y con desequilibrio de ligamiento, donde la correlación entre frecuencias genotípicas fue superior a 0.25. Se estimó los niveles de heterocigosis esperada (He) y observada (Ho), contenido de información polimórfica (CIP); así como, el índice de Shannon, el índice de fijación y tamaño efectivo de población (Ne). Se calculó la probabilidad de exclusión (PEC) y de identidad combinada (PIC). El panel final fue de 121, 188 y 113 SNP en HER, BRA y LIM, respectivamente; la principal fuente de descarte fue HW seguido de PIG. Los niveles de Ho y He fueron superior a 0.40; el PIC fue mayor a 0.32 y Ne presentó estimaciones por arriba de 181.3. Los resultados para la PEC fueron superiores a 0.999999; para la PIC, estuvieron por debajo de 1 x 10-20.

Published: December 2021

The aim of this study was to evaluate the effect of dietary supplementation with Agave fourcroydes powder on growth performance, carcass traits, organ weights, gut morphometry, and blood biochemistry in broiler rabbits. A total of 40 male rabbits (New Zealand × Californian) weaned at 35 d were randomly selected for a control diet (CD) and CD + 1.5% of A. fourcroydes powder, with 10 replicates and two rabbits per replicate. After 60 d, A. fourcroydes powder increased body weight, feed intake, and weight gain (P<0.05), without affecting feed conversion ratio and viability (P>0.05). Furthermore, this natural product did not affect the edible portions and the indicators determined in the Longissimus dorsi, nor the organ relative weights and the intestinal morphometry (P>0.05); however, a decrease in cecal pH was observed and consequently an increase in cecal beneficial bacteria (P<0.05) were found. Also, A. fourcroydes powder reduced (P<0.05) the serum concentration of glucose, harmful lipids, HDL and atherogenic index although without change for the ureic nitrogen, creatinine and VLDL (P>0.05). Agave fourcroydes powder as a zootechnical additive promoted better growth, in addition, it showed lipid-lowering and hypoglycemic effects, without modifying the edible portions and organs digestive.
Diversidad de aves acuáticas de laguna Barrosa, Tierra del Fuego, Chile
Authors: Jaime Cárcamo , Humberto Cortés
Published: December 2021

Laguna Barrosa es una de las cuatro grandes lagunas que se ubican en el noroeste de Tierra del Fuego, a 20 kilómetros de la ciudad de Porvenir. Esta laguna no se ha mencionado en la literatura y no se conoce como un sitio importante para la conservación de la avifauna en la región de Magallanes. En este trabajo se describe la estacionalidad de las aves acuáticas a través de 10 visitas realizadas desde abril de 2015 a enero de 2016. Se registró un total de 24 especies de aves acuáticas, de las cuales 9 se encuentran en alguna categoría de conservación, dentro de las que destacan el canquén colorado (Chloephaga rubidiceps) y chorlo de Magallanes (Pluvianellus socialis), ambas categorizadas En Peligro (EN). Las especies caiquén (Chloephaga picta), pato juarjual (Lophonetta specularioides) y cisne coscoroba (Coscoroba coscoroba) dominaron el ensamble en todas las estaciones del año, tanto en términos de abundancia como en frecuencia de ocurrencia. Se destaca la abundancia del cisne coscoroba, la cual representa entre un 4 y 10% de la población mundial y la importancia de la laguna como sitio de invernada del flamenco chileno (Phoenicopterus chilensis), ave que se encuentra casi amenazada. El análisis de similitud demostró que la estructura del ensamble de aves del humedal presenta una tendencia temporal de tipo estacional. En general, destacamos a laguna Barrosa como un importante sitio de descanso y alimentación para las aves acuáticas de Tierra del Fuego y la región de Magallanes.

Violent Memory: Haruki Murakami’s Hard-Boiled Wonderland and the End of the World
Authors: Mattar Netty
Published: December 2021

Modern information technologies have radically transfigured human experience. The extensive use of mnemonic devices, for instance, has redefined the subject by externalizing aspects of inner consciousness. These transformations involve the incorporeal but deeply felt, violent dislocations of human experience, traumas that are grounded in reality but which challenge symbolic resources because they are difficult to articulate. I am interested in how the unseen wounding of mnemonic intervention is registered in the “impossible” language of speculative fiction (SF). SF is both rooted in the “real” and “estranged” from reality, and thus able to give form to impossible injuries. This paper argues that Haruki Murakami uses the mode of SF in his novel, Hard-Boiled Wonderland and the End of the World, to explore how mnemonic substitutes interfere with the complex process of remembering World War II in Japan. I will demonstrate how, through SF, Murakami is able to give form to an unseen crisis of memory in postwar Japan, a crisis marked by the unspeakable shock of war and by the trauma that results from the intrusion of artificial memories upon one’s consciousness of history.
Politically Marginalized Female Figures: Female Grassland and Celestial Bath
Authors: Li Katherina
Published: December 2021

Yan Geling’s early work Female Grassland雌性的草地 (Yan, 1989) is a novel published in 1989, while Celestial Bath 天浴 (Yan, 2008) is a short story published in 1996. Both of Yan Geling’s works focus on female sent-down youth, with stories set in the grasslands of the Tibetan pastoral countryside during the mid-1970s, in the waning years of the Cultural Revolution 文化大革命 (1966-1976). This paper discusses women’s fragmentation to analyze the obstacles to women’s liberation during the sent-down youth movement, illustrating how female sent-down youth’ tragic experiences resulted because of political power.

Published: December 2021

This study investigated X-raying the million-point agenda of Nigerian government by library and information professionals in the country. Six objectives were formulated to guide the study. A descriptive survey research design was adopted using the online Google Form to collect data/responses from the library and information science (LIS) professionals in Nigeria. The population of the study comprised LIS professionals in all the states in Nigeria. The sampling technique used for the study was the total enumeration sampling technique (120) as the whole responses were used for the analysis using tables, frequencies percentages, mean and standard deviation for easy appreciation and comprehension. Statistical Package for the Social Sciences (SPSS) version 23 was also deployed and it was found out that there appears to be some high level of corrupt practices in the country, Nigeria, insecurity as of today remains on the high side which is not only worrisome but disturbingly a threat to too many households. Respondents have rated the economy to be at its lowest ebb as the majority of the citizens now wallow in poverty and agony, education standard is quite low in the country, there are deliberate steps to take in order to save Nigerian country from war and disintegration. To this very end, the well-informed class including library and information professionals should deliberately rise up to their duty by not just studying the current situation but also proffer recommendations and solutions to disturbing problems; hence recommendations are all Nigerians, irrespective of position or social, status must resolve to live a corrupt-free life; Government and all security agencies must be on the alert and, if possible, request international assistance; economic policies must be reviewed as a matter of urgency in Nigeria; education must be made easily accessible and funds made adequately available for educational institutions at all levels as prescribed by UNESCO; library and information professionals should continue to put government officials on their toes by regularly exposing their inadequacies to the citizens amongst others.
Exilio interno y campo psi en Córdoba durante la última dictadura militar. Primeras aproximaciones e interrogantes
Authors: Vissani Laura , Scherman Patricia , Fantini Nilda
Published: December 2021

Se busca comprender mejor la configuración del campo psi en Córdoba durante la última dictadura militar. Se analizan los espacios de encuentro y formación profesional que se desarrollaron y se discute si estos pueden ser definidos como prácticas de resistencia en condiciones de exilio interno. Se examina la noción de exilio interno en tanto enfatiza no sólo los desplazamientos de lugar geográfico, sino la mudanza de hábitos a la cuales los exilados se vieron sometidos. Se propone analizar la conformación de grupos de estudio -constituidos como estrategias alternativas de formación y lectura-, como prácticas de resistencia entendidas al modo foucaultiano. La figura de pliegue destacada por Deleuze, permite considerar la configuración de un espacio donde se hace posible eludir la violencia ejercida por el poder y continuar desarrollando un modo de hacer con otros, por fuera de los estrechos marcos regulatorios que imponía la dictadura.Palabras Clave: Dictadura argentina - Psicología- Historia reciente- Exilio interno
Contemporizing island biogeography theory with anthropogenic drivers of species richness
Authors: Gleditsch Jason , Behm Jocelyn , Ellers Jacintha , Jesse Wendy , Helmus Matthew
Published: December 2021

Classic ecological theory must explain effects of humans on biodiversity
to be more applicable today. We contemporized island biogeographic
theory providing native, introduced, and total species richness
relationship expectations with natural and anthropogenic metrics of
habitat diversity (geographic and economic area) and isolation from
source pools (geographic and economic isolation). We assessed these
expectations across Caribbean island herpetofauna clades. As expected by
the contemporized theory, natural habitat diversity metrics exhibited
positive relationships with native and introduced richness,
strengthening positive total richness-area relationships. Geographic
isolation exhibited negative relationships with native and positive
relationships with introduced richness, weakening total
richness-isolation relationships. Economic area and isolation exhibited
negative and positive relationships, respectively, with native richness
but positive and negative relationships, respectively, with introduced
richness. Total richness relationships with economic area and isolation
were strongest in clades with many introductions. As more species spread

Eriyik yığma modelleme, 3B yazıcıların gelişimi ve çeşitlenmesi ile sanayi ve evsel kullanımda tercih edilen önemli bir teknoloji haline gelmiştir. Ancak, 3B yazıcılarda yazdırılan parça dayanımını etkileyen parametre sayısı oldukça fazladır. Bu çalışmada, 3B yazıcı kullanılarak üretilen numunelerde yazdırma açısının mekanik özelliklere etkisi deneysel yöntem ve sonlu elemanlar metodu kullanılarak incelenmiştir. Test numunelerinin yazdırılmasında PLA filament ve farklı yazdırma açıları (0°, 45°, 90°) kullanılmıştır. Sonlu elemanlar analizinde numuneler transvers izotropik malzeme olarak kabul edilmiştir. Malzemenin plastik davranışı Hill akma kriteri ile tanımlanmıştır. Çalışmanın ilk aşamasında, 0°, 45° ve 90° yazdırma açıları için sonlu elamanlar analiz sonuçları ve deneysel sonuçlar karşılaştırılmıştır. Karşılaştırma sonuçları, yazdırılan numunelerin dayanımının belirlenmesinde transvers izotropik malzeme kabulü ve Hill akma kriterinin kullanılabileceğini göstermiştir. Çalışmanın son aşamasında, 15°, 30°, 60°, 75° yazdırma açıları için sonlu elemanlar analizleri tekrarlanmıştır. Sonlu elemanlar analizi ve deneysel sonuçlar, numunelerin mekanik özelliklerinin ve maksimum yük değerlerinin yazdırma açısının artması ile belirgin şekilde yükseldiğini göstermiştir.
Management of a Patient With Tracheal Stenosis After Previous Tracheotomy
Authors: Takaishi Kazumi , Kawahito Shinji , Kitahata Hiroshi
Published: December 2021

Tracheal stenosis after tracheotomy can cause difficult airway management and respiratory complications. It is difficult to predict tracheal stenosis after tracheotomy based on a patient's symptoms as the symptoms of tracheal stenosis appear only after they become severe. In patients with a history of previous tracheotomy, it is important to consider the risk factors for tracheal stenosis. Detailed preoperative evaluation of patients with a history of previous tracheotomy is essential and should include 3-dimensional assessment of the airway.

We report the preoperative assessment and perioperative management of an 83-year-old woman at high risk for tracheal stenosis due to a previous emergency tracheotomy who was scheduled to undergo general anesthesia for a right maxillectomy for squamous cell carcinoma. Preoperative anteroposterior chest radiograph revealed findings indicative of tracheal stenosis. Additional detailed examinations of the stenotic area were conducted with computed tomography imaging and bronchofiberscopy. General anesthesia with nasotracheal intubation was performed, and although there were no adverse intraoperative events, stridor after extubation was observed. Nebulized epinephrine was administered via an ultrasound nebulizer and effectively improved the patient's postoperative transient dyspnea.

Some anesthetic agents or adjunct medications administered during general anesthesia can cause an accelerated idioventricular rhythm (AIVR), which is associated with higher vagal tone and lower sympathetic activity. We encountered AIVR induced by vagal response to injection-related pain following local anesthetic infiltration into the oral mucosa during general anesthesia. A 48-year-old woman underwent extraction of a residual tooth root from the left maxillary sinus under general anesthesia. Routine preoperative electrocardiogram (ECG) was otherwise normal. Eight milliliters of 1% lidocaine (80 mg) with 1:100,000 epinephrine (80 μg) was infiltrated around the left maxillary molars over 20 seconds using a 23-gauge needle and firm pressure. Widened QRS complexes consistent with AIVR were observed for ∼60 seconds, followed by an atrioventricular junctional rhythm and the return of normal sinus rhythm. A cardiology consultation and 12-lead ECG in the operating room produced no additional concerns, so the operation continued with no complications. AIVR was presumably caused by activation of the trigeminocardiac reflex triggered by intense pain following rapid local anesthetic infiltration with a large gauge needle and firm pressure. Administration of local anesthetic should be performed cautiously when using a large gauge needle and avoid excessive pressure.

Authors: Prince Jordan , Goertzen Cameron , Zanjir Maryam , Wong Michelle , Azarpazhooh Amir
Published: December 2021

Objective:

Serious airway complications can occur with inadequate airway management during general anesthesia (GA). This meta-analysis investigated randomized controlled trials that compared perioperative technique failures and airway complications, including hypoxia, during GA for dentistry using endotracheal intubation or a laryngeal mask airway (LMA) for airway management.

Methods:

A systematic search of electronic databases and gray literature was completed. Independent reviewers assessed eligibility, performed data extraction, completed risk of bias assessment, and judged the quality of results through Grading of Recommendations, Assessment, Development, and Evaluation. Risk ratios (RRs) for airway complications, with 95% CIs, were calculated. Heterogeneity was quantified using the I2 statistic. Sensitivity and age-subgroup analyses were explored.

Results:

Six trials were deemed eligible from a total of 9076 identified reports. The airway management intervention for these trials was LMA. Technique failures or effect differences in airway complications were not detected except for postoperative hypoxia, where LMA use had a decreased risk (RR, 0.22; 95% CI, 0.06-0.77; I2 = 0%; moderate quality). A similar effect was seen in the pediatric analysis (RR, 0.10; 95% CI, 0.01-0.84; I2 = 0%; moderate quality). Additionally, LMA use reduced pediatric sore throat risk (RR, 0.08; 95% CI, 0.04-0.15; I2 = 0%; moderate quality).

Conclusion:

Use of an LMA in dentistry may have the potential to reduce the risk of postoperative hypoxia, particularly in pediatric patients, although further study is required.
The volatility of natural gas prices - Structural shocks and influencing factors

Published: December 2021

The paper examines the primary drivers and factors influencing the volatility of natural gas prices in the world from January 2007 to July 2020. In addition to the narrow dependence between crude oil and natural gas prices, the influence of renewable energy production and coal production on the price of natural gas has been studied. For that purpose, the method of multiple linear regression was used. The results show that the volatility of natural gas prices significantly depends on the type of the shock in the natural gas market, and that the total production of energy from renewable sources, production of coal and natural gas and the price of crude oil have a significant impact on the price of gas.
