Effect of the Growth Regulator Paclobutrazol and Fertilization on Defensive Chemistry and Herbivore Resistance of Austrian Pine (Pinus nigra) and Paper Birch (Betula papyrifera)
Authors: Chorbadjian Rodrigo , Bonello Pierluigi , Herms Daniel
Published: November 2021

The Growth/Differentiation Balance Hypothesis predicts that environmental factors that limit growth of plants more than their rate of photosynthesis should increase secondary metabolism and resistance to insects. Soil drench application of the plant growth regulator paclobutrazol slowed the growth of paper birch (Betula papyrifera) and Austrian pine (Pinus nigra) with no effect on photosynthesis. In response, foliar concentrations of condensed tannins (but not total phenolics) in birch increased as predicted, which increased birch resistance to gypsy moth (Lymantria dispar) and whitemarked tussock moth (Orgyia leucostigma), but only during the second season after treatment. In both years, there was a negative correlation between foliar concentrations of total phenolic and condensed tannins and growth of paper birch, which is consistent with the predicted trade-off between growth and defense. Conversely, in Austrian pine, paclobutrazol and fertilization did not have an effect on foliar concentration of tannins, phenolics, and terpenes, nor did the treatments have any effect on resistance to European pine sawfly (Neodiprion sertifer). Hence, the effects of paclobutrazol on tree growth, defensive chemistry, and insect resistance were species-specific and time sensitive.

Solar Powered Self-Charging Circuit for Mobile Applications
Authors: Kulkarni Padmashree V , Jahnavi A , L Madhurya
Published: November 2021

Electric vehicles were invented as an alternative to save fuel and to make more environment-friendly vehicles. With the increase in pricing for fuels, all are looking at effective alternatives for fuelled vehicles. Although electric vehicles [EV] are alternatives for our daily means of travel, they have not been very effective with the distance we can travel by fully charging them. The problem with EV is that once fully charged they may run for about 60 km. But considering our society, most of us travel more than 60 km every day. An alternate EV will make a better future. In this project we have aimed at making EVs more efficient and effective for normal usage. We have implemented a prototype of a new circuit with two batteries where each battery works alternatively. Apart from this, we have used solar panels to charge these batteries with solar energy.
Association between senescence of T cells and disease activity in patients with systemic lupus erythematosus

Published: November 2021

Introduction

Systemic lupus erythematosus (SLE) patients are predisposed to chronic immune activation, leading to accelerated immunosenescence. The aging of the immune system causes the T cells to express several senescence markers such as CD57 and KLRG1, which produce pro-inflammatory cytokine interferon  (IFN-). Immunosenescence was associated with high morbidity and mortality in other diseases. This research was conducted to prove the association between senescent T cells and SLE disease activity.

Material and methods

This research was an observational cross-sectional study on 53 women aged 16–45 years diagnosed with SLE based on SLICC 2012 criteria. All subjects were recorded for demographic and clinical data, and their SLE disease activity index (SLEDAI) score was measured to evaluate disease activity. Active disease was defined as SLEDAI score ≥ 3. The CD57 antigen and KLRG1 expression on CD4+ and CD8+ T cells were calculated from peripheral blood mononuclear cells (PBMC) by flow cytometry. Interferon  was measured from serum using ELISA. The comparison was done using the Mann-Whitney test, and correlation was tested using the Spearman test. Associations between variables were calculated using linear regression models.

Results

Systemic lupus erythematosus patients with active disease had markedly higher CD4+KLRG1+ (3.1 [1.3–5.5]% vs. (0.3 [0.1–0.5]%), CD8+CD57+ (11.6 ±7.1% vs. 2.4 ±2.0%, p = 0.000), and CD8+KLRG1+ T cell percentages (13.7 ±7.5% vs. 0.3 ±0.1%, p = 0.000), and IFN- levels (208.9 [148.3–233.8] vs. 146.7 [130.2–210.8] pg/ml, p = 0.048), compared to the inactive patients. Positive correlation and association was found between the CD8+CD57+ and CD8+KLRG1+ percentages with the SLEDAI score (p = 0.007 and p = 0.007, for the linear regression analysis, respectively).

Conclusions

Systemic lupus erythematosus patients showed significantly higher senescence T cell markers compared to controls, and the increase of T cell senescence, especially in the CD8 compartment, has some association with increased disease activity in patients with SLE.

Published: November 2021

Introdução: Nos últimos anos, melhores biomateriais ortopédicos estão sendo necessários. Tendo em vista que, implantes nessa área se tornaram um produto básico da indústria médica e, o envelhecimento da população somado à cultura atual de estilos de vida ativos contribui para o crescimento desse cenário. Objetivo: Entender o uso da biotecnologia na ortopedia, em especial no desenvolvimento de próteses. Material e Métodos: Esse estudo trata-se de uma revisão de literatura utilizando a base de dados PUBMED. Dessa forma, foram usados os descritores: “Biotechnology” e “Orthopedic prostheses” combinados com o operador booleano “AND”. Os critérios de inclusão foram: artigos completos; publicados em português ou inglês, entre os anos de 2016 a 2021. Já o critério de exclusão foi apenas a não pertinência com o tema escolhido. Por fim, após leitura e avaliação das publicações, foram selecionados ao final um total de 3 artigos. Resultados: Alguns estudos indicam que há eficácia no uso materiais de nanotecnologia para ossoimplantes. Uma vez que, além da osteoindução, pistas osteoindutivas nano e microtopográficas também podem reduzir a inflamação e possuir uma atividade antibacteriana para promover ainda mais a regeneração óssea. Conclusão: Materiais de andaime, contendo pistas micro topológicas ou nanotopológicas em sua topografia, são cruciais para apoiar a cura endógena após acidentes, infecções ou ressecção de tumor e, assim, contribui para a regeneração óssea. Embora o futuro dos nano-biomateriais seja promissor, os efeitos de longo prazo das micro e nanoestruturas no corpo devem ser estabelecidos antes que as nanotexturas possam ser usadas em superfícies de implantes ortopédicos como forma de inibir a adesão bacteriana.

Entre el 12 y el 15 de diciembre de 1998, el IUDOP realizó un sondeo de opinión pública con una muestra de 1,239 adultos en todo el país, con un margen de error de más o menos el cuatro por ciento. La encuesta, diseñada para recoger la opinión de los salvadoreños a finales de 1998, revela que la población piensa que la delincuencia ha aumentado en el año que termina y que el problema económico sigue estando igual que antes, aunque hacen mayor énfasis en la pobreza y el desempleo. La pesquisa reveló también que los salvadoreños no están muy entusiasmados por la campaña electoral, y que el partido de gobierno mantiene una ventaja notable en las preferencias ciudadanas de cara a las elecciones presidenciales de 1999.

High-resolution modeling of glacier mass balance and surface runoff in western Norway driven by bias-corrected climate forcing
Authors: Gong Yongmei , Rogozhina Irina
Published: November 2021

Abstract. Western Norway hosts many glacierized drainage basins with complex terrain and local climate. These drainage basins face challenges related to long-term planning of hydropower production and flood risk mitigation under global warming. To enable forward vision of such efforts, bias-corrected outputs from state-of-the-art regional climate models and reanalysis provide climatic forcing for impact simulations. We utilize a distributed, process-based snow evolution model with a daily temporal and 100 m × 100 m spatial resolution to investigate the applicability of different bias-corrected climate forcing data for multidecadal reconstructions of glacier surface mass balance and surface runoff regimes in western Norway. These simulations are driven by climatic forcing from the bias-corrected NORA10 hindcast in 2000–2014, which has been produced specifically for western Norway and treated as a benchmark dataset, as well as ten bias-corrected and uncorrected CORDEX outputs under different Representative Concentration Pathway scenarios in 2000–2020. Downscaled drainage basin-wide air temperature, precipitation and glacier-wide surface mass balance are then validated against observations. The variables mentioned above produced by the benchmark simulation match available observations well. The mean annual surface mass balance of glaciers in most glacierized basins is negative in 2001–2014, and its evolution is mainly correlated with trends in annual snowfall. There is a general negative west to east gradient in seasonal and annual unit area runoff, which peaks between 2005 and 2008 in most drainage basins. Snow meltwater is the largest contributor to both seasonal and annual runoff in all drainage basins except for two of the westernmost ones. Drainage basins with denser glacier coverage turn out to have a later peak runoff discharge date. The correction applied to the CORDEX forcing reversed the cold bias in the original datasets, while the agreement between bias-corrected and observed precipitation rates varies strongly from basin to basin. As a result, simulations driven by bias-corrected CORDEX datasets produce lower annual surface mass balance in the most and least glacierized drainage basins, i.e., Basin 1 and 17, respectively. They all produce more unit area runoff in Basin 1 and less in Basin 17 both seasonally and annually, with only a few exceptions. We conclude that the identified errors will likely be inherited by the results of the future projections, casting doubts on the applicability of bias-corrected CORDEX forcing to directly drive local scale projections and the modeled outputs in developing climate change adaptation strategies.
The Sensitivity of the Fitch Wind Farm Parameterization to a Three-Dimensional Planetary Boundary Layer Scheme

Published: November 2021

Abstract. Wind plant wake impacts can be estimated with a number of simulation methodologies, each with its own fidelity and sensitivity to model inputs. In turbine-free mesoscale simulations, hub-height wind speeds can significantly vary with the choice of a planetary boundary layer (PBL) scheme. However, the sensitivity of wind plant wakes to a PBL scheme has not been explored because, until now, wake parameterizations were only compatible with one PBL scheme. We couple the Fitch wind farm parameterization with the new NCAR 3DPBL scheme and compare the resulting wakes to those simulated with a widely used PBL scheme. First, we simulate a wind plant in a pseudo-steady state under idealized stable, neutral, and unstable conditions with two PBL schemes: MYNN and the NCAR 3DPBL. For these idealized scenarios, MYNN consistently predicts internal wakes that are 0.25–1.5 m s−1 stronger than internal 3DPBL wakes. However, because MYNN predicts stronger inflow winds than the 3DPBL, MYNN predicts average capacity factors that are as large as 13 percentage points higher than with the 3DPBL, depending on the stability. To extend this sensitivity study, we conduct a month-long case study with both PBL schemes centered on the Vineyard Wind 1 lease area in the mid-Atlantic United States. Under stable and unstable conditions averaged across the month, MYNN again predicts stronger internal waking—by about 0.25 m s−1. However, again due to stronger plant inflow wind speeds in MYNN, the 3DPBL generates 4.7 %–7.8 % less power than MYNN in August 2020, depending on the turbine build-out scenario. Differences between PBL schemes can be even larger for individual instances in time. These simulations suggest that PBL schemes represent a meaningful source of modeled wind resource uncertainty; therefore, we recommend incorporating PBL variability into future wind plant planning sensitivity studies as well as wind forecasting studies.

Robust stability of switched positive linear systems
Authors: Le Van Ngoc
Published: November 2021

The aim of the present paper is to give robust stability based on exponentially stable switched positive linear systems. Our theoretical analysis shows that if there exists a positive stable system of all positive subsystems, then a lower bound and upper bound for stability radius of the switched system under positive affine perturbations are established. In the particular case of two dimensional switched system, including two switching signals, we obtain a formula of stability radius. Several examples are provided to illustrate our approach.

This study was conducted to provide data on the weed species composition of the Cyperaceae and Poaceae in the rice fields in An Giang province. The study results show that the weed species composition of Cyperaceae and Poaceae families is very diverse with 38 species belonging to 25 genera, of which 27 are usable. The largest number of species is in crop 1 and in the fields inside the ring dike. Although the species composition is diverse, only a few species are very high frequencies, and most of the remaining species have very low frequencies. Chau Phu district has the highest weed density, averaging 28.42 trees/m2. Weed density in crop 1 is highest in the 3 crops (15.79 trees/m2). Fields outside the ring dike have a higher weed density than paddy fields inside the ring dike (15.37 trees/m2). Although crop 1 has more species abundance than crop 3, the species diversity and the species equality in the weed community in crop 1 are lower than crop 3. Rice fields inside the ring dike have higher species abundance than those outside the ring dike, but the indicators H 'and 1 – λ are lower.

Activities of anthropological organisms lead to the production of massive lignocellulosic waste every year and these lignocellulolytic enzymes plays crucial role in developing eco-friendly, sustainable and economical methods for decomposing and pre-treating the biomass to produce biofuels, organic acids, feeds and enzymes. Lignocellulolytic enzymes sustainably hydrolyse the biomass and can be utilized in wide range of applications such as personal care, pharmaceutical, biofuel release, sewage treatment, food and beverage industries. Every year a significant ton of biomass waste is released and insight on these crucial enzymes could establish in all the industries. However, due to the increased demand for compost materials, biomass degradation has resulted in composting processes. Several methods for improving compost amount and quality have been explored, including increasing decomposer inoculums, stimulating microbial activity, and establishing a decomposable environment. All of these prerequisites are met by biotechnological applications. Biotechnological procedures are used to improve the activity of enzymes on biomass. It leads to an adequate supply of compost and base materials for enterprises. In terms of effectiveness and stability during the breakdown process, lignocellulolytic enzymes derived from genetically modified species outperformed naturally derived lignocellulolytic enzymes. It has the potential to increase the quality and output of by-products. This review discussed the development of lignocellulolytic enzyme families and their widespread applications in a variety of industries such as olive oil extraction, carotenoid extraction, waste management, pollution control, second-generation bio-ethanol production, textile and dyeing, pharmaceuticals, pulp and paper, animal feed, food processing industries, detergent, and agricultural industries.

Relationship between Budget Deficit and Economic Growth: Evidence from Ethiopia
Authors: Emana Desalegn
Published: November 2021

This study examined the relationship between budget deficit and economic growth in Ethiopia using time series data for the period 1991 to 2019 by applying the ARDL bounds testing approach. The empirical results indicate that budget deficit and economic growth in Ethiopia have a negative relationship in the long run, and have a weak positive association in the short run. In line with this, in the long run, a one percent increase in the budget deficit causes a 1.43 percent decline in the economic growth of the country. This result is consistent with the neoclassical view which says budget deficits are bad for economic growth during stimulating periods. Moreover, in the long run, the variables trade openness and inflation have a positive impact on Ethiopian economic growth, and on the other hand, the economic growth of Ethiopia is negatively affected by the nominal exchange rate in the long run. Apart from this, in the long run, gross capital formation and lending interest rates have no significant impact on the economic growth of the country. Therefore, the study recommends the government should manage its expenditure and mobilize the resources to generate more revenue to address the negative impact of the budget deficit on economic growth.

Published: November 2021

Existen múltiples lesiones quísticas que se pueden encontrar en el encéfalo y en la fosa posterior. Entre estas, una nueva entidad denominada MV PLUS (por su sigla en inglés de multinodular and vacuolating posterior fossa lesions of unknown significance) tiene características imagenológicas similares al tumor multinodular vacuolante, pero como lo indican su sigla en inglés, está localizado en la fosa posterior. Estos tumores se definen como un conjunto de lesiones subcorticales nodulares pequeñas, de alta señal en secuencias con informaciónT2-FLAIR, con o sin realce al administrar medio de contraste. Pueden diferenciarse de otras entidades quísticas porque son lesiones agrupadas, sin cambios inflamatorios reactivos, presentes en una corteza de apariencia normal y sin evolución en el seguimiento. Esto último hace que se consideren lesiones benignas, no agresivas. Se presenta el caso de un paciente de 21 años de edad, a quien de manera incidental se le encontró en la región central del vermis una lesión de aspecto multiquístico, sin cambios durante el seguimiento en los últimos 3 años, con diagnóstico probable de MV PLUS.

casa de las fincas cafeteras como patrimonio agroindustrial colombiano en riesgo
Authors: Santa Quintero Ángela María
Published: November 2021

El presente artículo se origina a partir de uno de los trabajos de campo realizados durante mis estudios académicos para la Maestría en Restauración de monumentos arquitectónicos de la Pontificia Universidad Javeriana de Bogotá. En este texto se exponen algunos de los hallazgos alcanzados para entonces, remozados con información actualizada y pertinente sobre las casas de dos fincas cafeteras y un sector poblado, situados en el Departamento de Caldas, Colombia. Los tres objetos de estudio se incluyen con el fin de analizar y valorar el patrimonio agroindustrial de la zona cafetera; la vivienda como unidad productiva y la cultura asociada a ella como herencia viva. Aunque el propósito inicial fue identificar en los diferentes niveles de caficultura la tradición, el conocimiento, las técnicas y la memoria de trabajo, la arquitectura y el paisaje industrial, como elementos del patrimonio cultural en el territorio; en este artículo sólo se presenta el análisis de las viviendas campesinas de la zona de estudio, de los peligros que se cierne sobre ellas y por ende, del riesgo que existe para el paisaje cultural cafetero como patrimonio. Para ello se habla, en primera medida, sobre las nociones de patrimonio industrial, y la metodología empleada, para luego abordar las características físicas de las casas cafeteras, sus valores patrimoniales y las posibles amenazas que enfrenta actualmente el patrimonio agroindustrial en la zona cafetera del país.

El presente documento busca conocer los principales cambios entre los periodos previos y posteriores a la apertura económica de Colombia, con respecto a la demanda y la oferta juvenil, a través de un análisis exploratorio descriptivo con un corte longitudinal de tres periodos. La fuente de los datos comienza con los hallazgos del trabajo de Ocampo (1986) basados en la Encuesta Nacional de Hogares y una nueva elaboración de análisis de datos de la misma encuesta, en un periodo posterior a la apertura económica. Este documento también hace una breve descripción bibliográfica donde se muestran estudios que nacen de la preocupación de analizar las mismas variables macroeconómica que estudia Ocampo y el presente documento, y gracias a esta se elaboran una serie de hipótesis que se contrastan con los resultados de la encuesta. Entre los principales hallazgos encontramos que después de la apertura hay una mayor proporción de los jóvenes en la población ocupada, el sector financiero e industrial emplean a la mayoría de jóvenes hay actualmente más técnicos y tecnólogos que universitarios en los puestos de trabajos y existe una precarización de los ingresos de forma considerable.
Educación en Colombia: el enfoque por competencias y la ʻ'glocalizaciónʼ
Authors: Milazzo R. Maurizio
Published: November 2021

En la dicotomía entre universalismos y localismos, la cultura occidental hegemónica eurocentrista ahora llega a sus límites. En este contexto, y dado que no se puede pensar en un solo patrón cultural global en el que quepan todas las formas plurales de cultura, emerge la necesidad de educar tanto sobre postulados universales foráneos, como sobre saberes locales. El enfoque particular de competencias acogido y promocionado por el Ministerio de Educación Nacional de Colombia logra retraídamente armonizar estos extremos de globalidad y localidad.

En medio de la pandemia, y frente a las incertidumbres del futuro, el Marco Fiscal de Mediano Plazo, elaborado por el Ministerio de Hacienda para el período 2021-2031, muestra que la crisis no ha llevado al gobierno a replantear el tipo de Estado. Colombia seguiría con una intervención pública muy débil. Además de mostrar la inconveniencia de continuar con un Estado raquítico, el artículo pone en tela de juicio el modelo de proyección basado en el equilibrio estacionario. A partir de esta lógica estrecha se termina concluyendo, de manera equivocada, que el crecimiento inmediato de la economía colombiana será en forma V.

El presente artículo recoge el ejercicio investigativo desde un enfoque cuantitativo-descriptivo acerca del análisis de la percepción del área humanista con énfasis en proyecto de vida de tres instituciones educativas de básica y media del municipio de Soacha (Cundinamarca, Colombia). La recolección de datos se realiza a través del instrumento EFFA (Escala de Expectativas de Futuro en la Adolescencia), con el objetivo de identificar la percepción de los estudiantes de las tres instituciones elegidas acerca de su proyección de vida a mediano plazo. El instrumento EFFA fue diseñado y validado en tres investigaciones previas (Sánchez Sandoval y Verdugo, 2016) y posteriormente adaptado antes de su aplicación en esta investigación. Como resultados de esta investigación, se evidenció que cuanto mayores son las expectativas de futuro de los adolescentes, mayor es también su autoestima, lo que no solo se refleja en su autoconcepto, sino también en la calidad de sus relaciones interpersonales y en su capacidad de vincularse a la sociedad. Lo anterior favorece que los jóvenes con mayores expectativas de futuro aprovechen de mejor manera las oportunidades que les ofrece el entorno para elevar su calidad de vida, aun en los casos en los que no se accede a canales de movilidad social a través del ingreso a instituciones educativas de tercer nivel.

Published: November 2021

O presente estudo toma como objeto de análise sociolinguística e sócio-histórica o emprego da Concordância Nominal (CN) de número entre os elementos do interior do Sintagma Nominal (SN) no Português Afro-brasileiro, registrado em amostras de fala da comunidade quilombola de Rio das Rãs, no município de Bom Jesus da Lapa, no oeste do Estado da Bahia, corpus constituído pelo Grupo de Pesquisa em Linguística Histórica e em Sociofuncionalismo da Universidade Estadual do Sudoeste da Bahia (UESB). Analisamos os grupos de variáveis linguísticas através da perspectiva atomística (marcas precedentes, tonicidade, saliência fônica, posição do constituinte com referência ao núcleo e classe gramatical) e da perspectiva não atomística (função sintática do SN, realização do núcleo, posição do SN em relação ao verbo e saliência fônica) (SCHERRE, 1988) e as variáveis extralinguísticas (sexo, faixa etária, escolaridade e estada fora da comunidade), considerando empiricamente o desempenho dos falantes quanto à aplicação da regra de concordância estabelecida pela gramática normativa. Seguindo as premissas teórico-metodológicas da Teoria da Variação e Mudança Linguística (LABOV, WEINREICH, HERZOG, 2006[1968]; LABOV, 2008 [1972]) e Sócio-histórica (ROMAINNE, 1982), os dados foram analisados quantitativamente, utilizando o programa estatístico Goldvarb-X (SANKOFF, TAGLIAMONTE, SMITH, 2005) estabelecendo uma relação entre as variáveis linguísticas e extralinguísticas, para observar o comportamento linguístico da comunidade através das amostras de fala. Foram utilizados 3.519 dados retirados das entrevistas de 24 informantes, sendo verificada a aplicação de regra da concordância nominal de número em 24% das ocorrências analisadas. Os dados obtidos nesta pesquisa fornecem evidências, sobre o vernáculo do oeste baiano, relacionadas aos caminhos da variação e mudança linguística que remontam a sócio-história do Português Brasileiro (PB).

Indonesia Army troops as the vanguard are always required to be professional in always carrying out high-risk tasks after the command over with high responsibility successfully. War (OMP) is an area that will be attacked or occupied by troops as a base and defended if the task still requires it. Activities carried out in operations such as issuing combat robots to find and track targets both during the day and at night automatically from threatening enemies. Therefore we need a tool that can help in carrying out tasks during the day and night. Tracking is the process of tracking and locking the target, which can be used to track and lock an object. One example of tracking is object tracking, security at night has both advantages and disadvantages, especially in conditions with very low light intensity. So night vision is needed to become a more effective security camera. Based on these problems, a study was made on bringing about automatic target identification and tracking on the N2MR3 a version of the CIA combat robot using the pattern recognition method to maximize security in conditions with very low intensity. The results of the study indicate that this study provides results in reading objects in light and dark conditions.
