Safety of building constructed on hillside slope
Authors: Yushchube S. V. , Podshivalov I. I. , Larionov A. S.
Published: February 2021

The paper focuses on the pile foundation and footing of the building constructed on a hillside slope and consisting of four three-dimensional blocks. The building is arranged such that to protect the first block constructed on the footslope from the negative technogenic influence of the latter via the embedment of three supporting blocks into the hillside slope. The first three-dimensional block is a three-storey brick building, while the other three are the spatial supporting structures made of insitu reinforced concrete. All the blocks locate at different position levels. The resulting embedded part of the structure matches the class KS-3 construction site safety. It is thus necessary to assess the structural safety of the building constructed in difficult engineering and geological conditions. The MicroFe software is used for finite element dimensional calculations of the pile foundation and footing strength, stability and oscillation after studying the engineering-geological surveys, the analysis of the soil formation, composition and physicalmechanical properties, the piling field. Also, the theoretical model is proposed for the footingfoundation–building system. The obtained results allow assessing the stress-strain state of the pile foundation and footing with the lateral support to the hillside slope of soil.
Standardized design in Western Siberia late in the 1950–60s
Authors: Dukhanov S. S.
Published: February 2021

The paper deals with the problems of standardized design in civil construction in the cities of Western Siberia during the architectural reform late in the 1950–60s and is based on archival sources.

First, the development continuity of design and civil engineering industry was broken that time, thereby reducing to nothing the accumulated positive experience in standardized design and sharply limited the adaptation of design projects to regional conditions. Second, the methods of standardizing generated by the architectural reform were based on the universal factors and numerical criteria. That approach was aimed at centralizing the management of the design and construction industry, but did not take into account the leading regional factors and sharpened their adverse impact. It was impossible to develop projects on this basis that would meet local climatic and socio-economic conditions. Large local design organizations created during the architectural reform were forced to develop standardized projects for the conditions of Western Siberia, contrary to the main trends of the architectural reform. As a result, research and development played catch-up the civil construction and prolonged until the early 1970s.

В работе Катерины Кудрявцевой перспектива рассмотрения загадочного образа из Апокалипсиса иная — не богословская, а, скорее, религиоведческая. Но религиоведческая точка зрения не может не включать в себя богословскую, иначе она рискует исказить свой предмет — религию, обойдя вниманием её вероучительную сторону. К. Г. Кудрявцевой удалось прийти к богословскому рассмотрению образа религиоведческим путём, а именно путём расшифровки его семантики. В этом смысле её исследование подобно работе с красками, восстанавливающими цвета фрески до первоначальной яркости (пусть виртуально, чтобы не вмешаться с новой кистью в исторически сохранившиеся слои), в то время как схема рисунка и его сюжет остаются теми же самыми. К. Г. Кудрявцева берёт за основу нарратив видения св. апостола Иоанна, который она разделяет на четыре аспекта и даёт им довольно поэтические названия: «Застигнутая жизнью и смертью»; «Свечение»; «Противостояние как погоня»; «Город». По этим четырём ключевым темам распределена на параграфы каждая из пяти глав работы, которые охватывают мировой фольклор, корпус канонических книг Ветхого Завета, письменность эпохи Второго Храма, литературный контекст Откровения св. Иоанна Богослова (то есть тоже произведения периода Второго Храма, но наиболее близкие по развитию своей образности к Апокалипсису) и, наконец, сам текст Откровения.

In Katerina Kudryavtseva's work, the perspective of the enigmatic image from the Apocalypse is different - not theological but, rather, religious studies. But a theological perspective could not avoid incorporating a theological perspective, otherwise it would risk distorting its subject, religion, by neglecting its doctrinal side. K.G. Kudryavtseva was able to reach a theological consideration of the image in a theological way, namely by deciphering its semantics. In this sense, her research is like working with paints, restoring the colours of a fresco to their original brightness (albeit virtually, so as not to intervene with a new brush in the historically preserved layers), while the scheme of the drawing and its subject remain the same. K.G. Kudryavtseva takes as a basis the narrative of St. John's vision, which she divides into four aspects and gives them rather poetic titles: "Caught in Life and Death"; "Illumination"; "Confrontation as Chase"; "City". Each of the five chapters is divided into paragraphs according to these four key themes, covering world folklore, the corpus of canonical books of the Old Testament, the writing of the Second Temple period, the literary context of the Revelation of Saint John the Evangelist (that is, also works from the Second Temple period, but closest in their development of imagery to the Apocalypse) and, finally, the text of Revelation itself.

Maize roots will show varying growth responses to the type of fertilizer given. The objective of this study was to determine the effect of N, P, and K fertilizers on the growth of maize roots and the function of the relationship between root dry weight and shoot dry weight of maize under rizhotron. The research was conducted in April - June 2019 at the screen house and Plant Laboratory, Politeknik Lamandau in Lamandau Regency. The research was conducted in rizhotron's growth medium which was arranged in a completely randomized design (CRD) with a fertilizer treatment consisting of urea (N = 200 kg ha-1), SP36 (P = 100 kg ha-1), KCl (K = 100 kg ha-1), and control (without fertilizer) with three replications. The results showed that N fertilizer was able to provide better root dry weight growth compared to P and K fertilizer, namely 2.59 g. Root dry weight has a significant effect on plant dry weight gain based on the function of y = 4.10x + 0.06 (R2 = 0.96 **).

Published: February 2021

This study aimed to examine the effect of applying organic pellet fertilizers from vermicompost and Azolla using coal fly ash as an adhesive on paddy crop response in swampland. The research was performed in a pot experiment using a completely randomized factorial design with two treatment factors. The organic pellet fertilizer doses were: 0 ton ha-1 (a control); 10 ton ha-1; 20 ton ha-1; and 30 ton ha-1 as the first factor. In the second factor, the different NPK fertilizer dose was applied: the absence of NPK fertilizer as a control; 0.5 and 1 time of the recommended dose. The results showed that the application of organic pellet fertilizer significantly improved soil pH but not significant on soil organic C and N levels. There was tendency of increased on soil pH, C-organic, and N-total with the increased doses of organic pellet fertilizers applied. The NPK fertilizer application significantly improved plant height, tiller number and plant biomass as the dose were rised up. The organic pellet fertilizer application significantly improved plant height, number of tillers, and plant biomass. Applying organic pellet fertilizer at a dose of 10 tons ha-1 should be sufficient as no further improvement with the increasing doses.

Published: February 2021

Liquid waste from processing cassava into tapioca starch is carbohydrate-rich waste and can be used as a growth medium for the Acetobacter xylinum, which is useful in producing one of the fermentation products, i.e. nata. Several factors influence the production of nata, one of them is the addition of nutrients in the form of nitrogen in the fermentation medium. The nitrogen source used is usually from inorganic fertilizers, such as urea and ammonium sulfate. In this study, fermentation of tapioca starch wastewater was developed, using a natural sources of nitrogen derived from soybean and green bean sprouts extract. Nata was made by treating various concentrations of soybean and green bean sprouts extract (3%, 4%, 5%) and fermentation time (6 days, 7 days, 8 days, 9 days and 10 days). The characteristics of the nata product were seen from the thickness and yield of the nata. The nata de cassava product's optimum results were tested for thickness, yield, and moisture content. The results showed that the best type of natural nitrogen source was soybean sprouts extract 5%, fermentation time of 10 days with a thickness of 0.55 cm, the water content of 97.58%, and yield of 63.09%

BACKGROUND: Bioimpedance spectroscopy has been suggested as a useful tool for early diagnosis of breast cancer–related lymphedema (BCRL). We aimed to describe the outcomes of published studies that evaluated bioimpedance analysis as a method for prospective surveillance and early diagnosis of BCRL. METHODS: We queried the PubMed, Ovid Medline, and EMBASE databases to identify studies that evaluated use of bioimpedance spectroscopy as a diagnostic tool. We used the keywords “bioimpedance” AND (“lymphedema” OR “lymphoedema”) in the search. Only English-language studies that reported quantitative outcomes for patients with BCRL were included. RESULTS: Of 152, 235 and 116 identified articles in PubMed, Ovid Medline and EMBASE databases, only 22 were included. Use of bioimpedance analysis for prospective surveillance has been shown to prevent chronic BCRL. All the cross-sectional and retrospective studies that evaluated bioimpedance for diagnosis of BCRL reported significantly different L-Dex scores between lymphedema patients and healthy participants; in addition, bioimpedance scores were positively correlated with volume of lymphedema. CONCLUSION: Bioimpedance analysis is a potential tool with demonstrated benefits for prevention of chronic BCRL and may be an economic and great alternative for early diagnosis of BCRL.

Heterogeneous identity trust management method based on risk assessment
Authors: Zhu Wenye , Tan Chengxiang , Xu Qian , Xiao Ya
Published: February 2021

The cross-trust domain environment in which heterogeneous identity alliances are located often does not have a completely trusted centralized trust root, and different trust domains and entities also have specific security requirements. In view of the above problems, we believe that trust measurement of cross-domain identities based on risk assessment is an effective method to achieve decentralized proof of user identities in heterogeneous cyberspace. There are various risk assessment models. We choose the more mature attack graph theory in the existing research to apply to the new field of cross-trust domain management of heterogeneous identities. We propose an attribute attack graph evaluation model to evaluate cross-domain identities through risk measurement of attributes. In addition, heterogeneous identity alliances also have architectural risks, especially the risk of decentralized underlying structures. In response to this problem, we identify the risk of the identity alliance infrastructure, and combine the risk assessment and presentation system design to verify the principle.

Published: February 2021

Background:

Ryanodine receptor 1-related myopathy (RYR1-RM) can present with a selective pattern and gradient of intramuscular fatty infiltration (IMFI) on magnetic resonance imaging (MRI).

Objective:

To demonstrate an automated protocol for quantification of IMFI in the lower extremity muscles of individuals with RYR1-RM using T1-weighted MRI and to examine the relationships of IMFI with motor function and clinical severity.

Methods:

Axial images of the lower extremity muscles were acquired by T1-weighted fast spin-echo and short tau inversion recovery (STIR) sequences. A modified ImageJ-based program was used for quantification. IMFI data was analyzed by mode of inheritance, motor function, and clinical severity.

Results:

Upper and lower leg IMFI from 36 genetically confirmed and ambulatory RYR1-RM affected individuals (26 dominant and 10 recessive) were analyzed using Grey-scale quantification. There was no statistically significant difference in IMFI between dominant and recessive cases in upper or lower legs. IMFI in both upper and lower legs was inversely correlated with participant performance on the motor function measure (MFM-32) total score (upper leg: p < 0.001; lower leg: p = 0.003) and the six-minute walk test (6MWT) distance (upper leg: p < 0.001; lower leg: p = 0.010). There was no significant difference in mean IMFI between participants with mild versus severe clinical phenotypes ( p = 0.257).

Conclusion:

A modified ImageJ-based algorithm was able to select and quantify fatty infiltration in a cohort of heterogeneously affected individuals with RYR1-RM. IMFI was not predictive of mode of inheritance but showed strong correlation with motor function and capacity tests including MFM-32 and 6MWT, respectively.
The Role of Nutrition and Physical Activity as Trigger Factors of Paralytic Attacks in Primary Periodic Paralysis
Authors: Welland Natasha Lervaag , Hæstad Helge , Fossmo Hanne Ludt , Giltvedt Kaja , Ørstavik Kristin , Nordstrøm Marianne
Published: February 2021

Background:

Primary periodic paralysis (PPP) are rare inherited neuromuscular disorders including Hypokalemic periodic paralysis (HypoPP), Hyperkalemic periodic paralysis (HyperPP) and Andersen-Tawil syndrome (ATS) characterised by attacks of weakness or paralysis of skeletal muscles. Limited effective pharmacological treatments are available, and avoidance of lifestyle related triggers seems important.

Objective:

Our aim was to search and assess the scientific literature for information on trigger factors related to nutrition and physical activity in PPP.

Methods:

We searched Ovid Medline and Embase database for scientific papers published between January 1, 1990, to January 31, 2020.

Results:

We did not identify published observation or intervention studies evaluating effect of lifestyle changes on attacks. Current knowledge is based on case-reports, expert opinions, and retrospective case studies with inadequate methods for description of nutrition and physical activity. In HypoPP, high carbohydrate and salt intake, over-eating, alcohol, dehydration, hard physical activity, and rest after exercise are frequently reported triggers. Regarding HyperPP, fasting, intake of potassium, alcohol, cold foods or beverages, physical activity, and rest after exercise are frequently reported triggers. No nutrition related triggers are reported regarding ATS, exercise can however induce ventricular arrhythmias.

Conclusions:

Our results support that dietary intake and physical activity may play a role in causing paralytic attacks in PPP, although the current scientific evidence is weak. To provide good evidence-based patient care, several lifestyle aspects need to be further assessed and described.

While Spinal Muscular Atrophy (SMA) has historically been managed with supportive measures, the emergence of innovative medicines has given those living with SMA hope for improved quality of life and has revolutionized care. Despite these advances, the use of therapies and changes in disease management strategies have focused on pediatric populations, leaving adults living with SMA, and those transitioning into adulthood, relatively neglected. Through a multi-faceted approach that gathered unbiased perspectives from clinical experts, validated insights from individuals with lived experiences, and substantiated findings with evidence from the literature, we have exposed unmet needs that are hindering the field and, ultimately, impacting care and quality of life for adults living with SMA. Here, we set new aspirations and calls to action to inspire continued research in this field, stimulate dialogue across the SMA community and inform policies that deliver effective management and care throughout an adult’s journey living with SMA.
A SURVEY ON ONCOPLASTIC BREAST SURGERY AWARENESS AND PRACTICE PATTERNS AMONG INDIAN SURGEONS: A CROSS-SECTIONAL STUDY
Authors: Mishra Vinayak , Kelkar Rajashri , Agrawal Aditi , Matcheswalla Sakina
Published: February 2021

Purpose: To assess the perspective and practice patterns of Indian surgeons concerning OBS and compare urban and rural areas.

Patients and methods: A thirteen-question survey was distributed through the social media platform WhatsApp (WhatsApp Inc, California, US) to various Indian surgical society groups across India from 5th May 2020 to 19th May 2020. The questions focused on the surgeons' experience, surgical management technique of choice in breast cancer patients, acceptance and practice of OBS, knowledge of type 1 and type 2 OBS, and axilla management.

Results: Two hundred ninety surgeons responded to the survey out of about 1000, with a response rate of 29%. 17.99% of the surgeons (n=52) practiced in a rural region, while 82.01% (n=237) practiced in an urban region. 94.12% (n=272) of the surgeons reported awareness about oncoplastic breast surgery (OBS), whereas only 5.88% (n= 17) were unaware of the existence of this procedure.  62.97% (n=182) surgeons offered OBS to their breast cancer patients, while 37.02% (n=107) did not offer OBS. 49.37% of surgeons in the urban areas do not perform OBS, whereas 78.85% do not perform it in the rural regions. It also highlights that the percentage of surgeons performing OBS with a plastic surgeon (29.41%) is higher than those who carry out the procedure by themselves (15.92%).

Conclusion: Most of the Indian surgeons are aware of OBS. In the rural areas, OBS's rate is minimal due to various reasons such as poverty, illiteracy, inaccessible radiotherapy centers, and the absence of training of surgeons in OBS. Few urban surgeons perform OBS themselves while most of them do it with the help of plastic surgeons. Mastectomy is the most commonly performed surgical intervention for breast cancer in rural regions. The practice of OBS should increase in India to improve the postoperative quality of life of breast cancer patients.

Published: February 2021

Pest attack on the forest can have an impact on the productivity and quality of existing stands (such as reducing average plant growth, decreasing seed germination power, and appearance of forest aesthetics). This study aims to identify the types of pest management and analyze the relationship between perception and community actions in the community forest in Karyasari Village, Leuwiliang District, Bogor Regency. Data collection is done by semi-structured interview, observation and recording of secondary data. The type of pest management carried out by the community uses three pest management techniques, including chemical, mechanical and a mixture of chemical and mechanical. Farmers do not use biological techniques. Mechanical pest management is less used in society compared to chemical management. Many farmers use chemical management techniques with pesticides because they kill pests quickly. In addition, some small farmers use a mixture of chemical and mechanical management. There is a relationship of perception with the characteristics of respondents, such as land area, education and role in society. There is a relationship of action with the characteristics of respondents, such as the role in society, land area, education and employment.

A agricultura representa um dos principais pilares da economia brasileira, sendo sua importância relacionada à segurança alimentar e à geração de oportunidades de trabalho. Entretanto, é necessário que haja uma reflexão crítica sobre a sustentabilidade do plantio. Entre os diversos tipos de culturas, o tomate destacou-se como um dos frutos mais plantados e consumidos do mundo. O presente artigo traz uma avaliação comparativa entre três tipos de plantio do tomate: convencional, orgânico e sustentável (TOMATEC®), desde o preparo do solo à comercialização no mercado. O trabalho foi realizado no norte fluminense do estado do Rio de Janeiro, junto a grupos que produzem o fruto nesses três tipos de plantio. A metodologia foi alicerçada em um questionário não estruturado, com respostas livres, aplicado aos agricultores da região. Acreditamos que este estudo contribuirá para a orientação da sociedade através de dados obtidos a partir de sérios critérios de processamento de informações. Os principais resultados mostraram, através do sistema sustentável de plantio da EMBRAPA (inovação), que é possível utilizar agrotóxicos com consciência ambiental e produzir frutos livres de resíduos. As doenças, no sistema convencional, são controladas pela aplicação de fungicidas e bactericidas. No plantio sustentável, utiliza-se uma mistura de detergente caseiro com óleo de soja, calda bordalesa, leite de vaca, fungicidas de contato e fungicidas sistêmico, e, no sistema de produção orgânica, é comum não deixar a doença se instalar na planta, através do controle preventivo do preparo e da proteção do solo. No controle de pragas, o sistema convencional realiza a aplicação inseticidas compostos por variados princípios ativos. No sistema orgânico, privilegia-se o controle de insetos através do equilíbrio do solo, com isso, as plantas adquirem maior resistência às doenças e pragas. No sistema sustentável, não há tratamento preventivo, e sim curativo. Os preços do fruto no mercado para o plantio convencional sofrem flutuações e dependem da oferta, enquanto os tomates dos sistemas orgânico e sustentável não apresentam flutuações. A produção orgânica não tem capacidade instalada para atender às demandas de mercado. Com isso, o sistema sustentável vem ganhando espaço no mercado e se expandindo pelos Sudeste e Sul do país.
Consenso de la OCDE sobre Créditos a la Exportación con Apoyo Oficial. Marco actual, evolución y desafíos
Authors: Arranz Jaime Alcaide
Published: February 2021

El Consenso OCDE es el marco de gobernanza internacional para la financiación oficial a la exportación, surgido del "pacto entre caballeros" alcanzado en 1976 en el seno del G6, en un contexto de competencia agresiva, con el propósito de dotarse de reglas objetivas a favor de una competencia basada en la calidad de los bienes y servicios en lugar de en los términos de la financiación ofrecida, para preservar un terreno de juego equilibrado, level playing field, y reducir las distorsiones sobre el comercio internacional. Desde los años ochenta ha existido un continuo proceso de desarrollo y adaptación del acuerdo. No obstante, el Consenso hace frente en la actualidad a una creciente pérdida de influencia y representatividad, con un peso relevante de la actividad de países no participantes o de prácticas desarrolladas al margen de este. El contexto de polarización y fragmentación actual dificulta la coordinación y la creciente agresividad de la competencia podría implicar de nuevo una carrera a la baja con efectos negativos sobre el comercio internacional. Frente a un nuevo periodo de incertidumbre, el reciente lanzamiento de trabajos para un proceso de modernización del Consenso es un paso positivo, pero será necesario un elevado grado de compromiso político y el impulso de nuevas iniciativas de coordinación a favor de un marco de gobernanza verdaderamente global.

Authors: Canadell Casanova Eudald , Cambón Murcia María Isabel
Published: February 2021

El desarrollo y análisis de la política macroprudencial más allá de la banca ha avanzado de forma significativa durante los últimos años si bien dicho desarrollo en Europa no ha sido homogéneo ni sencillo. En el ámbito de los fondos de inversión existen multitud de herramientas destinadas a mitigar tanto los riesgos de desajuste entre la liquidez y el vencimiento (reembolsos) de estas instituciones como el riesgo de apalancamiento. De todas ellas, la posibilidad de suspender los reembolsos es, por el momento, la única herramienta común a todos los Estados miembros de la UE, mientras que el resto muestran una disponibilidad y uso muy diferente entre Estados. En este sentido, España pertenece al grupo de países con el número más elevado de herramientas a su disposición, algunas de las cuales han sido adoptadas recientemente.

Authors: Velázquez Arellano María Elena , Benavente Valdés Juan Roberto , Morlett Chávez Jesús Antonio , Aguilar González Cristóbal Noé
Published: February 2021

En esta revisión se describen los principales factores que afectan la producción de pigmentos por Monascus en medio sólido, así como los diferentes residuos utilizados y aquellos potenciales remanentes regionales en México que pueden ser aprovechados en la producción de pigmentos. Los colorantes producidos por el hongo Monascus han mostrado potencial aplicación en las industrias alimentaria, cosmética, farmacéutica y textil. La producción de pigmentos por Monascus se ha llevado a cabo principalmente en cultivos en estado sólido, para lo cual el uso de residuos agroindustriales como fuente de sustrato es una alternativa real que incrementa la factibilidad económica del proceso, aunado a ser una alternativa de bajo impacto ambiental. Los factores de temperatura, pH, humedad relativa y tamaño de partícula se identificaron como los factores de mayor influencia en la producción de pigmentos. Los residuos regionales de maíz, arroz y Aloe vera son los sustratos con mayor rendimiento.
Análisis de un sistema de información geográfica para la interpretación de cartas de campo magnético y geológico del semidesierto de Zacatecas
Authors: Casas Flores Héctor Miguel
Published: February 2021

El semidesierto de Zacatecas ha sido un gran impulsor del desarrollo económico que se ha sostenido a nivel industrial debido a la cantidad, calidad y cotización de minerales que se encuentran dentro de las 13 imponentes formaciones litológicas del estado. La región de estudio abarca aproximadamente 3,744 km2 y se caracteriza por tener rocas de composición basáltica, riolítica, rocas intrusivas como granodioritas, monzonitas de la Era Cenozoica (Terciaria) y también rocas metamórficas caracterizadas por el tipo de metamorfismo de contacto de grado medio a bajo. El análisis de multivariables fue utilizado para construir diagramas jerárquicos (dendrogramas) y mapas de similitudes. Los principales puntos magnéticos de alta susceptibilidad magnética lo obtienen las formaciones de la Era Cuaternaria, Terciaria, Cretácica Temprana y Jurásica Tardía, lo que implica que sobre estas capas de roca y en algunas estructuras minerales profundas se obtenga el mayor contenido de minerales ferromagnéticos.

A muestra de 60 sujetos divididos aleatoriamente; Grupo b: recibieron bupivacaína a 0.5% en una dosis de 0.2mg/kg vía intratecal con 0.5 ml de solución fisiológica y Grupo d: recibieron bupivacaína a 0.5% en una dosis de 0.2 mg/kg vía intratecal con 5 μg de dexmedetomidina en 0.5 ml de solución fisiológica.
Vegetación de Sierra Rica: el papel de la biogeografía en la formación de las comunidades vegetales en Manuel Benavides, Chihuahua, México
Authors: Juárez Pérez Alicia , Melgoza Alicia , Fernández Jesús A.
Published: February 2021

Sierra Rica pertenece al Área de Protección de flora y fauna Cañón de Santa Elena, en el municipio de Manuel Benavides, Chihuahua, México y se considera una isla del cielo biogeográfico. Aquí se presenta una caracterización biogeográfica del área que se pretende ayude a entender la magnitud de su diversidad vegetal y sus patrones de distribución. Se realizó una revisión bibliográfíca complementada con visitas al área de estudio. El origen geológico fue durante la actividad volcánica presente en la era Cenozoica que dio lugar a factores físicos importantes para la distribución de la vegetación. Entre estos factores se identifican microclimas, aspectos fisiográficos y edafológicos, y entre los aspectos bióticos, fuerzas evolutivas como la selección, microorganismos del suelo, mecanismos de dispersión e interacciones bióticas.

El estado de Coahuila, México, se caracteriza por la producción de queso artesanal elaborado a partir de leche de cabra. Este estudio se enfocó en el aislamiento, identificación y caracterización de bacterias ácido lácticas (BAL) presentes en este tipo de queso para usarlas como cultivo iniciador. Durante la investigación, se llevó a cabo el aislamiento e identificación de las BAL, caracterizándolas bajo pruebas bioquímicas tales como actividad acidificante, capacidad de inhibición, producción de CO2 y producción de aromas, y se seleccionaron aquellas que presentaron mejores características en las pruebas mencionadas anteriormente. Las BAL seleccionadas fueron preparadas para ser inoculadas en leche pasteurizada de cabra y, posteriormente, en la elaboración del queso. Los quesos se evaluaron mediante una prueba sensorial empleando la prueba diferencia de control, los resultados mostraron que los quesos enriquecidos con BAL presentaron características sensoriales globales diferentes al queso de cabra sin adición de BAL.

Published: February 2021

Los cambios socioeconómicos y las intervenciones sanitarias han mejorado la salud de la población mundial en las últimas décadas. Sin embargo, han empezado a presentarse modificaciones en la distribución de ciertas enfermedades debidas, principalmente, a lo que se conoce como cambio climático y que es una consecuencia más del deterioro del medio ambiente. Una de las preocupaciones derivadas de lo anterior es la redistribución o nueva geolocalización de las enfermedades transmitidas por vectores (ETV), ya que los vectores que las transmiten están encontrando nuevos nichos ecológicos en los cuales establecerse y multiplicarse. El objetivo de la presente revisión fue conjuntar la evidencia científica en torno al cambio climático y sus efectos en las ETV.

Published: February 2021

La invasión de especies biológicas es uno de los disturbios con mayores efectos negativos en los ecosistemas. En el Área Natural Protegida Sierra Fría, durante el 2013 se observó un insecto chupador afectando una población de Pinus greggii var. greggii. Para localizar más sitios infestados se realizaron recorridos por cuatro localidades donde se usó esta especie para reforestaciones. El insecto fue identificado usando claves específicas para el orden Membracidae y corroborado con especialistas en taxonomía. Para analizar la posible dispersión del insecto se realizó un monitoreo durante dos años en sitios con reforestaciones donde se usó P. greggii var. greggii. El insecto se identificó como Aconophora compressa Walker, una especie usada para el control biológico de plantas arvenses en cultivos tropicales. Durante los últimos dos años no se han observado nuevas infestaciones.

El objetivo fue conocer la contaminación por metales en sedimentos de la Laguna de Bustillos y comparar dos métodos de digestión (agua regia y peróxido). Se obtuvieron muestras en 15 puntos aleatorios de la superficie (0-10 cm) y de la parte inferior (10-20 cm). El análisis se realizó en un ICP-OES cuantificando cromo (Cr), fierro (Fe), litio (Li), magnesio (Mg), manganeso (Mn), níquel (Ni), zinc (Zn), cobalto (Co), cobre (Cu), plomo (Pb) y estroncio (Sr). Se efectuó un ANOVA bajo un arreglo factorial 2x2. Los resultados mostraron diferencias por el método de digestión (P<0.05), pero no por profundidad (P>0.05) o la interacción (P>0.05). La concentración de Cr, Fe, Mn, Ni, Zn, Cu y Pb no superó las normas nacionales o internacionales y para Li, Mg, Co y Sr no existen estándares.
