Osprey and white-tailed eagle in Northern Belarus: ecological niche comparison
Authors: Ивановский Владимир Валентинович
Published: November 2020

В последние десятилетия во многих европейских странах увеличилась численность орлана-белохвоста (Haliaeetus albicilla), естественно возник вопрос, как поведёт себя в этих условиях скопа (Pandion haliaetus), главный трофический конкурент орлана. С целью выявления наиболее напряженных параметров их экологических ниш было проведено сравнение «гнездовых выделов», гнездовых деревьев, архитектоники гнёзд, а также спектров питания скопы и орлана-белохвоста в Витебской области Белоруссии. Исследования показали, что с экологических и статистических позиций конкуренция между скопой и орланом возможна при добыче рыбы. Сравнительное изучение трофических ниш этих видов показывает, что ослабление пищевой конкуренции между этими видами достигается путем

In the light of the white-tailed eagle (Haliaeetus albicilla) population growth in many European countries we tried to find out how the osprey (Pandion haliaetus), which inhabits mainly the upland bogs of Northern Belarus and have similar to white-tailed eagle ecological niche, behave. Nesting biotopes, nesting trees, the architectonics of nests, as well as food spectra of the osprey and the white-tailed eagle in the Vitebsk region of Belarus were compared in order to identify the principal parameters of their ecological niches. Breeding territories were searched by using the circular plot census method modified by Dombrovski. Descriptions of nest site positions were done using the forest stand maps of local forest management divisions. Forest blocks and particular stands where the nests were situated or suspected to be situated were identified from the maps, and available state survey stand features were used. Diet was studied by standard methods. In the result of Morishita-Horn index calculation, it was shown that the competition between ospreys and White-tailed Eagles might occur during feeding on fish. The other parameters are not overlapped. Species solve this problem by preying on different fish size classes.
Phototropism of freshwater invertebrates in relation to their locomotion, habitats, respiration type, and diet
Authors: Николаева Наталья Евгеньевна
Published: November 2020

Установлено, что интенсивность и знак фототропизма у пресноводных беспозвоночных зависят от особенностей их передвижения, местообитания, питания и дыхания. У видов, активно плавающих в толще воды, наблюдались более высокие показатели положительного фототропизма, чем у бентосных. У животных, дышащих атмосферным кислородом, положительный фототропизм был выражен в большей степени, чем у животных с жаберным дыханием. При этом, чем больше потребность в кислороде или чем менее совершенны органы дыхания, тем ярче проявлялась положительная фотореакция. У хищников интенсивность положительного фототропизма выше, чем у растительноядных видов, и значительно выше, чем у детритофагов. У хищников обнаружена зависимость фотореакции от местообитания их пищевых объектов.

We found that the intensity and polarity of phototropism in freshwater invertebrates depend on the characteristics of their locomotion, habitat, diet, and the type of respiration. Actively swimming species showed higher rates of positive phototropism than benthic ones. In animals breathing atmospheric oxygen, positive phototropism was more pronounced than in animals with gill respiration. At the same time, the higher the need for oxygen or the less perfect the respiratory system, the wider the positive photoreaction. In predators, the intensity of positive phototropism is higher than in herbivorous species and significantly higher than in detritophages. The photoreaction of predators is also dependant on the habitat of their food objects.

Vitamin D Status in Cow’s Milk Protein Allergy
Authors: Pandiaraja Sumitha Grace , Maris Ioana
Published: November 2020

Introduction:Cow’s milk protein allergy (CMPA) affects 1.9 -4.9% of children worldwide and can be IgE-mediated or non-IgE mediated. Studies have highlighted the increased risk of inadequate vitamin D intake in children with CMPA on elimination diets, with potential effects on bone health, respiratory health and immune function. This study aims to investigate whether children with CMPA are at a higher risk of vitamin D insufficiency than their healthy counterparts.
Methods: This was an observational, cross-sectional study carried out at the specialist Paediatric Allergy Clinic, Bon Secours Hospital Cork and the Department of Paediatrics, Bon Secours Hospital Cork. 52 children with CMPA and 26 healthy controls, aged 6 to 24 months, were included. Exclusion criteria included known bone metabolism disorders, chronic renal and gastrointestinal disorders, and chronic infectious diseases. A retrospective chart review of children with CMPA was conducted to collect data on patient demographics, clinical presentation, and management. Serum 25(OH)D levels of children with CMPA (n=18) and healthy controls (n=26) were quantified and compared. Caregivers of children with CMPA were administered an online questionnaire to assess compliance to vitamin D supplementation.
Results: The serum 25(OH)D levels of children with CMPA were significantly lower than that of healthy controls (47.5 vs 62.5 nmol/L, p = 0.030). Among children with CMPA, children with IgE-mediated CMPA (p=0.041) and children with multiple concomitant IgE-mediated food allergies (p=0.011) had significantly lower serum 25(OH)D levels than their healthy counterparts. Among children with CMPA, breastfeeding status, reported vitamin D supplement use, age and gender were not significantly associated with serum 25(OH)D levels. The questionnaire revealed only 44.4% of caregivers to be fully adherent to vitamin D supplementation guidelines.
Conclusion:Children with CMPA are at higher risk of serum 25(OH)D insufficiency than healthy controls. Closer monitoring is required to ensure that vitamin D supplements are administered from birth to 12 months, at the recommended frequency.

Authors: Muhammad Hussain Qureshi  , Talat Hussain
Published: November 2020

Purpose: The issuance of green banking guidelines in 2017 has opened the door of a new banking horizon for Islamic banks because the objective of Islamic banks, objective of Shariah, objective of Islamic economic system and objective of green banking are linked. Banking, especially Islamic banking based on products and one of the main components of green banking guidelines is the development of green banking products. Since green banking is in the infancy stage, therefore, the objective of the study is to explore the issues and challenges in green banking products in Islamic and traditional banks of Pakistan. Methodology: Semi-Structured interview technique is utilized for data collection. The green operation managers and Shariah scholars of sample banks selected as interviewees. Interviews are conducted through telephonic recorded calls and email-interviewing. Total of 26 interviews are conducted. Findings: The results indicate that lack of skills, knowledge, identification of the target market with the appropriate mode of financing and convincing the people are some main obstacles in green banking product formulation and implementation. Implications: At one-point, green banking is an opportunity for Islamic banks to achieve Maqasid-e-Shariah on the other side, it may become an obstacle because it further limits the financing areas for Islamic banks. The situation needs serious attention from policymakers to act at earliest.

Features and Prospects of Building a Two-Contour Monetary and Financial System at the National and Regional Level
Authors: Zvonova E. A. , Kuznetsov A. V. , Pishchik V. Ya. , Silvestrov S. N.
Published: November 2020

Topic. The aggravation of geopolitical, environmental and social risks creates new uncertainty in international economic relations. The challenges of the fourth industrial revolution reinforced the monetary, financial and commercial-industrial confrontation between the old and new leaders of the global economy in an effort to maximize individual access to global financial, informational, natural, intellectual and technological resources. In the course of toughening global competition, the USA, as the issuer of the key reserve currency, continues to use the “exorbitant privilege” — extracting investment and financial rent from the global turnover of goods and services. The need to ensure economic security and maintain financial sovereignty in the context of ongoing economic sanctions encourages Russia to actively participate in the creation of a payment and settlement infrastructure independent of the US dollar.

Purpose. The article aims to summarise the experience of managing the economy based on the two-contour monetary system; secondly, to justify its use in creating an independent system of mutual settlements in the EAEU countries in the context of de-globalization and sanctions.

Methodology. In the study, we applied a dialectical approach. In conducting the study, we used general scientific methods of analysis, synthesis, generalization, as well as methods of systemic, historical-logical and comparative analysis.

Results. The functioning of a two-contour monetary system as a whole yielded positive and in some cases outstanding results of socio-economic construction and the creation of a new type of economy, such as, for example, the European model of the social market economy, the CMEA industrialization model, the Soviet economic model. A non-standard approach to the organization of financing of new industrialization in the Eurasian economic space was proposed based on the use of a two-contour monetary system.

Conclusions. The implementation of the project of cross-border settlements between the EAEU countries using the experience of a two-contour monetary system is a promising direction for the development of cooperation between Eurasian countries on a new economic basis.
Development of Human Capital in Russian “Smart” Cities: Networks and ‘Living labs’
Authors: Mukhametov D. R.
Published: November 2020

The article deals with the problems and opportunities of development of human capital in Russian “smart” cities. The formation of the digital economy involves new skills, knowledge and competencies associated with the use of new technologies. The high level of human capital is becoming particularly important in “smart” cities, where the introduction of digital technologies into the management system creates various exchange, control and regulation networks that ensure the self-organisation of urban management systems and the optimisation of the environment. The development of human capital becomes possible by choosing the most effective organisational solutions that would ensure access of residents to new technologies and infrastructure and create opportunities for cooperation between city authorities, residents, scientific and technical institutions and business. One of the most effective solutions is the creation of living labs — open innovation systems that provide cooperation of stakeholders, access of residents to new technologies, exchange of skills and experience, implementation of interdisciplinary projects, creation of grassroots innovations, and integration of educational and research activities. In Russia, centres of innovative youth creativity, technoparks, innovation clusters can be used to create living laboratories in “smart” cities. Сenters of innovative youth creativity is the most successful and perspective way to realise the living labs format. In this centres it is possible to build stable connections between the residents and various stakeholders, and provide development of intelligent systems focused on solving problems of urban governance. However, their development requires overcoming such issues as the coordination of the activities of various stakeholders, uneven territorial distribution of organisational opportunities, promotion of interdisciplinary research and development.

Social networks have firmly entered the lives of billions of global Internet users worldwide. They communicate in social networks, play online games, make purchases, organise online events — exchange content from all walks of life [1, 2]. The most popular and well-known services in Russia are Vkontakte (vk.com), Youtube.com, Facebook.com, Odnoklassniki (Ok.ru), etc. The interfaces of such platforms allo — fake accounts. In this paper, we propose an approach to detect bots using the LiveJournal social network as an example. For this, we investigated the characteristics of the user’s egograph and performed a comparative analysis of the results of the classification algorithms.
Political Economy and Forecasting Tools
Authors: Malov V. Yu. , Melentyev B. V.
Published: November 2020

Modern regional development strategies are implemented only for the part that meets the interests of corporations. The national economic approach is ignored. Western models within the framework of economics do not correspond to the state of the Russian economy. The theories of the peripheral economy of the 19th century were not only accepted but also realised during the reform of the economy of the Russian Empire. Loss of value with a “non-market” approach to exchange with other countries was considered as a necessary condition for “industrial education of the nation”. Examples of projects implemented in Siberia demonstrate this clearly. It is no secret that many infrastructure projects, in particular transport projects, are obviously unprofitable. Pipeline transport is created in the interests of mainly large resource-exploiting companies that prefer export destinations. The economic block of our government is focused on maximising cash income, and preferably as soon as possible. It should be recognised that the theories (scientific basis, if any) used to reform the Soviet economy of the 90s did not correspond to the object. Our economy was in a different environment of economic regulation, in which other laws apply. We propose to use the forecasting experience based on spatial models of the national economic level, which are based on the laws of political economy: maximisation of the degree of satisfaction of the needs of the country’s population, the law of planned (propor tional) development and the law of value.
National Innovation System of Israel at the Beginning of the 21st Century
Authors: Korotkov I. G.
Published: November 2020

Difficult geopolitical circumstances and natural resources scarcity laid down the vector of science and technology development of Israel. The only “natural resource” that was and still is in plenty — high-qualified human resource. As for today, Israel takes the first place in the world having its state support of public R&D as a per cent of GDP (4.5 per cent), the number of startup companies concerning population and quantity of researchers. Russia is interested in Israeli experience in the formation of a national innovation system (NIS) because of the same high state influence on the economics in this country. Powers of the state in Israel through the agency of the Office of the Chief Scientist (OCS) stimulate a wide variety of applied R&D and upon that do not prescribe the market how to develop but use targeted funding and state programs to reward the development of priority branches. In Russia, as opposed to Israel, the powers of state aim to play a vital role in chosen market segments, therefore suppressing the development of small enterprises. If in Israeli innovation economics the central place is occupied by the startup companies, in Russia, in the opposite, at the innovation market dominate the massive state-owned enterprises, restraining innovation processes that shift into low gear without business initiative. Israeli experience can be used in such innovation economics’ sectors as state support of innovations; technology transfer organization; commercialization of technologies, elaborated in Research and Development Establishment and universities; formation of international scientific and technological cooperation system; using of dual technologies; training of innovation managers.
Actual Problems of Sustainable Development and their Solution in Russia
Authors: Kochemasova E. Yu.
Published: November 2020

In the post-industrial period, which began in developed countries in the 1970s–1980s, the processes of globalization and competition in world markets came to the fore. As a result of the intensive development of industry and the growth of domestic consumption, many countries have largely exhausted the economic capacity of their territories. They are experiencing a shortage of raw materials. Over the past sixty years, the world’s leading countries have been implementing a socio-ecological and economic model of social development, which allows them to use financial, labour and natural resources rationally. Russia’s transition to sustainable development can give an additional impetus to the country’s socio-economic development. It also ensures breakthrough scientific and technological progress, increases the competitiveness of the national economy, creates other opportunities for more effective implementation of strategic planning documents and national projects.

A 2-((4-(hydroxymethyl)phenyl)(pyrrolidin-1-yl)methyl)phenol molecule is a biologically important alkylaminophenol compound. In the study, this new alkylaminophenol compound is synthesized by the Petasis reaction. The structural analysis of the molecule is performed by FTIR, 1H, 13C NMR, and UV-Vis spectrometry and supported by the computational spectral studies. The structural properties and quantum chemical calculations are carried out using the density functional theory (DFT) at the B3LYP and B3PW91 level with a 6-311++G(d,p) basis set. The NMR data are calculated by means of the GIAO method; the TD—DFT method is used for UV-Vis spectroscopy. In addition, the electronic and structural properties (bond lengths, dihedral and bond angles), HOMO and LUMO energies, NLO analysis, thermodynamic parameters (rotation constants, entropy, thermal energy, thermal capacity), vibrational frequencies, electrostatic potential (MEP), excitation energies, Mulliken atomic charges, and oscillator strengths are investigated. The results show that the molecular properties of alkylaminophenol compounds are theoretically and experimentally compatible.

Zn(II) Bis(N-ethyl-N-ethanol dithiocarbamate) (1) and its heteroleptic complexes derived from 2,2'-bipyridine (2) and 1,10-phenanthroline (3) are synthesized. Their spectroscopic and structural characterization is carried out using FTIR, 1H, 13C NMR, and the single crystals X-ray analysis. The interatomic data obtained from the structural studies show that the parent complex possesses a distorted trigonal bipyramidal geometry about the Zn metal, which changes to a distorted octahedral geometry upon increased coordination about the metal centre due to the addition of N-donor ligands. This addition also causes a change in Zn—S, C—S, and C—N bond lengths within the adduct complexes.

Контролируемое термическое разложение оксалатных солей — перспективный метод получения высокодисперсных материалов. В работе изучался процесс совместного разложения солей Mn и Ce при варьировании соотношения катионов, газовой атмосферы процесса (воздух и инертный газ). Для этого синтезирована серия оксалатов Mn и Ce методом соосаждения из водного раствора нитратов при соотношении Mn:Ce от 0:1 до 1:0. Методами рентгенофазового анализа и сканирующей электронной микроскопии показано, что происходит формирование оксалатов церия Ce(C2O4)3×10H2O и марганца MnC2O4×2H2O, увеличение содержания марганца ведет к росту количества соответствующих солей и изменению морфологии частиц. Результаты совместного использования комплекса физико-химических методов, таких как: термический анализ, in situ рентгеновская дифракция и масс-спектрометрия — показали, что разложение оксалатов осуществляется в две стадии и зависит от соотношения катионов, а также от атмосферы разложения. На первой стадии происходит потеря веса, сопровождающаяся уходом структурной воды, данный процесс ускоряется в токе инертного газа. Вторая стадия заключается в формировании оксидов из безводной соли и сопровождается выделением CO2 или CO/CO2. На воздухе за счет экзотермической реакции окисления разложение происходит при более низких температурах, чем в инертном газе. Введение марганца не сказывается значительным образом на температурных интервалах первой и второй стадии разложения соли. Однако добавление второго катиона оказывает влияние на продукт разложения: с увеличением содержания марганца происходит уменьшение размера частиц CeO2 и формирование простых оксидов марганца Mn3O4 на воздухе и MnO в инертной среде. Исследованы каталитические свойства в реакции окисления CO Mn, Ce-оксидов, полученных при разложении оксалатов в инертном газе и на воздухе. Показано, что катализаторы, сформировавшиеся в окислительной среде, более активные.

Feminism and communism: specifics of interaction in the western Ukrainian media discourse of the 1920s – 1930s
Authors: Khamedova Olha
Published: November 2020

The Subject of the Study is the models of interaction and intersection of ideologies in media discourse. In contrast to the homogeneous ideological discourse of the Soviet press, the Western Ukrainian of the interwar period was ideologically diverse, in particular, “leftist” ideas were propagated in magazines. There is a noticeable trend in modern media studies: researchers to some extent ignore the “communist segment” of the Western Ukrainian press of the interwar period, this is due to the relevance of our study. Realizing that the communist movement was not widespread in Western Ukraine during the interwar period, let us consider the press of communist organizations both for the sake of objectivity and the need to explore models of the intersection of communist ideology and feminism and this is the novelty of the research. The aim of the article is to investigate the specifics of the interaction of feminism and communism in the Western Ukrainian media discourse of the 1920s and 1930s on the material of communist magazines. The weekly Nasha Zemlya and Sel-Rob, which represented the communist ideological discourse of Western Ukraine, were selected for analysis. The research methodology is a combination of critical discourse analysis with feminist critique. The Results of the Study. Communist magazines were concerned about how to attract Ukrainian women to the party ranks. The key issues covered in Western Ukrainian communist magazines were: women’s unemployment, low-skilled workers, difficult conditions, and low wages. At the same time, only women journalists paid attention to the gender aspect of such problems, for example, the gender disparity in the remuneration of men and women. The political and ideological orientation of Western Ukrainian communist newspapers toward the Soviet Union and Moscow Bolshevism was obvious. Propaganda materials about the Soviet Union’s success in resolving the “women’s issue” regularly appeared in the newspapers of Western Ukrainian communists. Publications on women’s issues were feminist in terms of authorial Intentions, ideological accents, and interpretation of facts. However, discrimination against women was primarily due to an unjust socio-economic system. Despite feminist intentions in the materials of communist magazines, activists of the Ukrainian Women’s Union were criticized as the main ideological competitors in the struggle for the Ukrainian woman.

This study used a 2x2 between-subject experiment to examine the relationship between monetary incentives, task complexity and performance. Monetary incentives in this study were applied in two types, piece-rate and fixed-rate, while task complexity was varied in two categories, low and high. Participants’ performance was measured through the completion of tasks assigned. Results of this study indicates no effect of monetary incentive on performance, yet there is a significant effect of task complexity on performance where participants provided with tasks with low complexity showed a significantly higher performance than participants provided with tasks with high complexity. Furthermore, this study finds no interaction between monetary incentives and task complexity on performance. It is implied from this study that monetary incentives were not the main factors that contribute towards employees’ performance in the companies. Besides, task complexity is an important factor to be considered by firms, as it can influence their employees’ performance.

La degradación y erosión edáfica por cambios de uso suelo, disminuyen los contenidos de carbono y su calidad. Con el objetivo de identificar y reconocer los mejores indicadores de calidad edáfica y de relacionarla con sus contenidos de carbono orgánico, se realizó esta investigación en bosques de la Reserva de la Biósfera los Volcanes. Se seleccionaron 26 sitios distribuidos entre 2600 y 3800 m de altitud colectando muestras de suelo de 0 a -0.2 m para análisis físicos y químicos y entre 0 a -0.1 m para bioquímicos y biológicos. Los resultados mostraron como excelentes indicadores parciales para evaluar calidad del suelo (IpCS) al pH, porcentaje de arena; contenido gravimétrico de agua, carbono orgánico, Ca+2 y K+ intercambiables; carbono de biomasa microbiana y actividad fosfatasa ácida y presencia/abundancia de bacterias y algas. Con estos IpCS, se determinó aditiva y conmutativamente, calidad total del suelo (CSTsum y CSTmul) cuyas tendencias fueron similares, aunque el modelo aditivo, muestra mejor que bosques afectados y vegetación secundaria (2600 y 2700 m) tienen menor calidad edáfica, mientras que en la franja media (3000-3300 m) con bosques de Abies y mixto Abies-Pino, los suelos tuvieron mayores contenidos de carbono orgánico y altas CSTsum y CSTmul.

El sistema agroecológico tiene repercusión importante en el estado nutricional del suelo, que depende de su preparación y plantas que se cultivan. El presente trabajo tuvo como objetivo evaluar la influencia de diferentes sistemas agroecológicos en los indicadores químicos de un suelo cultivado de frijol (Phaseolus vulgaris L.). Se utilizó un diseño experimental de bloques al azar, ocho tratamientos y cuatro repeticiones. Los tratamientos fueron plantas de cobertura: frijol de puerco (Canavalia ensiformis, Adans.), mucuna (Mucuna pruriens), frijol gandul (Cajanus cajan (L.) Mill sp.), crotalaria (Crotalaria sp. L.) sembradas en dos sistemas de cultivos: monocultivo y asociadas con mijo (Pennisetum glaucum L.) y dos sistemas de sistema de preparación del suelo: convencional y siembra directa. Los indicadores químicos evaluados fueron: pH, materia orgánica, macro y micros nutrientes (P, K, Ca, Mg, Fe, Mn, Zn) y el rendimiento en el cultivo del frijol. El sistema de siembra directa tuvo influencia sobre los indicadores químicos del suelo, disminuyó el pH (5.26), altos contenidos de Ca y K, con valores de 1.64 y 73.21 mg kg-1 respectivamente, con respecto al sistema convencional. Los micronutrientes Cu y Zn tuvieron valores signif icativos de 0.97 y 1.38 mg kg-1 respectivamente, con respecto al sistema convencional. Los contenidos de Mg y K alcanzaron valores muy cercanos a los del suelo natural. En el rendimiento del cultivo del frijol se destacó el cultivo frijol de puerco con el mayor número de vainas por planta (14.25), granos por vainas (5.93) y granos por planta (84) y un rendimiento de 4.4 Mg ha-1.

Los efectos de la Oscilación del Sur El Niño pueden ser medidos como sus impactos sobre los rendimientos de los cultivos. Sin embargo, esos efectos sobre los cultivos principales en México han sido estudiados escasamente. En este trabajo, el objetivo principal fue identificar las correlaciones entre las anomalías de rendimiento medio anual desde 1980 hasta 2015 de los cultivos limón (Citrus limonia L. Osbeck) o naranja (Citrus sinensis L.) en México y la Oscilación del Sur El Niño (OSEN) al involucrar el Índice OSEN Multivariado Ampliado (MEI.ext) o el Índice Niño Oceánico (ONI). Los resultados indican que el OSEN y las anomalías de rendimiento medio anual de limón estuvieron no correlacionados. Por el contrario, los eventos extremos del OSEN en su fase El Niño han tenido efectos positivos sobre las anomalías de rendimiento medio anual de naranja, especialmente de julio a noviembre.

Se evaluó la eficiencia en fijación biológica de nitrógeno (FBN) de 27 cepas de Rhizobium spp. recolectadas en frijol silvestre y cultivado del occidente de México, al utilizar como hospedero la variedad de frijol Cuarenteño. El trabajo se realizó bajo malla sombra, se usó un diseño experimental completamente al azar con cinco repeticiones y se evaluaron longitud de vástago (LV) y de raíz (LR), peso seco de vástago (PSV) y de raíz (PSR), número de nódulos (NN) y peso seco de nódulos (PSN), nitrógeno total del vástago (NT) y contenido de clorofila (CL). Se realizaron análisis de varianza y de componentes principales; se obtuvieron índices de eficiencia por variable y por grupos de variables. Se detectaron diferencias altamente significativas (P ≤ 0.01) en seis de las ocho variables registradas. Por el valor per se de las variables, se seleccionaron Rhizojal VC3 colectada en frijol silvestre y Rhizojal ZCB3, Rhizojal ZCB1, Rhizojal TP2 y Rhizojal TP3 obtenidas en frijol cultivado. Por índices de eficiencia simples y por grupos de variables, se escogieron Rhizojal VC3, Rhizojal ZCB3 y Rhizojal TP2. El análisis de componentes principales separó a la mayoría de las cepas en dos grupos: cepas procedentes de la forma silvestre de frijol y cepas colectadas en frijol cultivado. Las cepas Rhizojal ZCB3, Rhizojal TP2 y Rhizojal TP3, mostraron los mayores valores en la escala del CP1; la cepa Rhizojal VC3, se ubicó del lado de los aislados de origen cultivado. Considerando los análisis realizados, las cepas identificadas como mejores en FBN fueron Rhizojal VC3 de frijol silvestre y Rhizojal ZCB3 y Rhizojal TP2 de origen cultivado. Los resultados indican que los índices de eficiencia contribuyen a la evaluación y selección de cepas por FBN y que existe potencial para identificar cepas de Rhizobium eficientes en FBN en la región occidente de México.

Windblown dust in desert areas can have serious impact on human health by inhaling f ine dispersed mineral particles as well as microorganisms as fungi. There is a lack of information above the microscopic fungal diversity in north Mexico; the aim of this study was to determine the arid soil micro-fungal genus in the municipalities of Ascension and Ciudad Juarez, MX bordering with United States. A Surface soil samples were collected at eight sites identif ied as the source of the dust storms. A total of 234 soil samples were analyzed for moisture content, texture and fungal genus. Soil moisture content was lower than 4% at 3 cm depth from surface. Predominant soil textural classes were clay loam and sandy clay loam, but high variability in percentages of clay, silt, and sand was observed. Fourteen fungal genera were found, Aspergillus sp. was the most dominant followed by Rhizopus sp., Phytium sp., Alternaria sp., and Bipolaris sp. Dominance of the Aspergillus sp. fungus in this study is important because is toxic and cause serious health problems including bleeding in the lungs, and the others genus have serious effects on human respiratory system, also are pathogenic to many plants and animals.

En escenarios de escasez de agua, el manejo del riego en cultivos es de gran importancia. El objetivo de este trabajo fue identificar la tensión de humedad (T) óptima en suelo para producir el mayor crecimiento y rendimiento de maíz (Zea mays L.) cultivado en el valle de Mexicali, Baja California, México. El cultivo fue establecido durante el ciclo primavera-verano de 2017. Los tratamientos evaluados fueron cuatro tensiones de humedad [(T); (10, 20, 30 y 40 kPa)] y seis genotipos de maíz (G). Los tratamientos se distribuyeron bajo un diseño de bloques al azar con cuatro repeticiones (arreglo factorial doble). El primer factor fue tensión de humedad del suelo y el segundo factor la variedad de maíz. Se midió el crecimiento del cultivo expresado como altura, número de hojas, días a floración masculina (antesis), y área foliar. Al final del experimento se cosecharon las mazorcas de cada tratamiento y se calculó el peso de grano, rendimiento y eficiencia en el uso del agua de riego. No se encontró una interacción significativa entre las variables de respuesta evaluadas (T × G) (P > 0.05). Durante los primeros 50 días después de la siembra, el factor que más afectó al crecimiento y desarrollo fue T. Con una menor T, menor fue el número de días para alcanzar la etapa de floración masculina (P < 0.05). El rendimiento y la eficiencia en el uso del agua de riego fueron afectados por T y G (P < 0.05). La variedad Asgrow RX 717 presentó la floración masculina en un menor tiempo que el resto de los genotipos, el más alto rendimiento (10.63 Mg ha-1) y la mayor eficiencia en el uso del agua de riego (48.79 kg ha-1 mm-1) que el resto de los genotipos evaluadas (P < 0.05).
