Published: July 2020

En Argentina, la producción agropecuaria familiar tiene una importante relevancia, tanto por el número deexplotaciones que existen, así como por la generación de empleo, arraigo y alimentos para consumo interno. En el Área Metropolitana de Buenos Aires (AMBA) existe una gran cantidad de “tambos pequeños” -definidos como establecimientos cuya actividad principal es la producción lechera, tienen un rodeo de hasta 100 vacas totales (VT), la mano de obra es predominantemente familiar y pueden contar con alguna instalación para el ordeñe-. El siguiente estudio forma parte del trabajo realizado en el marco de un Proyecto Especial de ProHuerta (N° 989/2017), adjudicado a siete productores tamberos familiares de La Matanza, Marcos Paz y Virrey del Pino. El objetivo del proyecto era garantizar el acceso al agua segura para consumo humano y animal, pero también se utilizó como insumo para profundizar en el estudio de las lógicas productivas que llevan adelante tamberos familiares que producen en un territorio complejo como el AMBA. Se utilizó el método basado en casos, la información fue recolectada mediante entrevistas semiestructuradas e información secundaria. De la información recabada se observó que los tambos tienen entre 7 y 45 VT, la tenencia de la tierra es un factor conflictivo, sus recursos forrajeros se encuentran deteriorados y la inseguridad e incertidumbre condiciona la continuidad de la actividad. Se resalta la pluriactividad –entendida en términos de actividades dentro de la explotación, así como a la combinación de la producción agropecuaria con ingresos extraprediales- como una de las estrategias utilizadas para garantizar la sustentabilidad de estos sistemas productivos.

Para la implementación de biofertilizantes se pretende que su formulación sea económica, de fácil aplicación yque garantice la eficacia del inóculo. Nuestro objetivo fue seleccionar un sustrato para vehiculizar Trichodermaharzianum Rifai y evaluar su efecto sobre plantas de pimiento (Capsicum annum L.). El desarrollo de biomasafúngica y esporulación se evaluó sobre 4 soportes orgánicos: arroz, salvado de trigo, turba, salvado detrigo+turba (1:1 v/v), que fueron inoculados separadamente con T. harzianum (1mL 1 x 108 conidios/1.250 cm3;incubados a 25°C). La mezcla de salvado de trigo+turba evidenció la mayor colonización fúngica y esporulacióna los 5 días posteriores a la inoculación (DPI). La mejor conservación de la viabilidad de conidios delbioformulado se mantuvo entre 4 y 25ºC durante 15 días, mientras que a 35 y 40ºC la viabilidad se redujosignificativamente (80%). La mayor formación de clamidosporas se observó a 4°C (76% a 35 DPI), con unareducción del 40-50% a 25 y 35°C. Cuatro cepas fueron bioformuladas en el soporte salvado de trigo+turba ytodas incrementaron el crecimiento vegetal en plántulas de pimiento a 45 DPI. La cepa FCC T 16 incrementó, enmás del 100% el desarrollo aéreo y la capacidad fotosintética. Las cepas FCCT 199-2 y FCCT 363-2favorecieron preferentemente el desarrollo radical.

Introduction

Hemoglobin/red cell distribution width (RDW) ratio (HRR) and lymphocyte-to-monocyte ratio (LMR) are two novel bio-markers associated with overall survival (OS) and prognosis in several types of cancers. The aim of this study is to investigate the value of HRR and LMR in newly diagnosed multiple myeloma (MM) patients.

Methods

A total of 180 patients were included in this study. Patients diagnosed with MM between May 2013 and May 2019 at a single center were evaluated. HRR was calculated by dividing hemoglobin to RDW, both measured from the same sample. LMR was calculated by dividing absolute lymphocyte count (ALC) to absolute monocyte count (AMC).

Results

The cutoff value for HRR was taken as 0.61, and the cutoff value for LMR was taken as 3.28. Patients were divided into low HRR, high HRR, low LMR, and high LMR groups. OS of the patients with low HRR was found lower compared with high HRR (36.7 months for low HRR and 53.2 months for high HRR, p < 0.001). Also, OS was found lower in the low LMR group (39.4 months for low LMR and 51.7 months for high LMR, p = 0.016). On multivariate analysis, low HRR and low LMR were predictive factors of OS (hazard ratio (HR) 2.08, 95% confidence intervals (CI) 1.31–3.03, and p = 0.002 for low HRR; HR 1.47, 95% CI 0.92–2.29, and p = 0.010 for low LMR).

Conclusion

Combining both HRR and LMR could be a prognostic biomarker and it reflects the status of the immune system in newly diagnosed MM patients.
Variations in the bathymetry and bottom morphology of the Izu-Bonin Trench modelled by GMT
Authors: Lemenkova Polina
Published: July 2020

Cartographic visualisation is a central concept in geoinformatics, and Generic Mapping Tools (GMT) functionality provides a variety of modules for effective mapping. However, due to its specific scripting approach, there is not enough reported experience of GMT mapping, comparing to traditional GIS. This contribution introduces steps that can be taken to perform cartographic mapping and modelling using GMT. Geographically, this paper investigates the Izu-Bonin Trench in the Pacific Ocean. The aim was to compare its geomorphology in two segments, and each was modelled by a series of profiles. The comparative analysis shows that the southern segment is deeper and is a more precisely V-shaped form with a steeper gradient slope. The northern part has an asymmetric slope with submarine terraces to the west and a straight shape to the east. The northern profile is based on 407 samples (13.5%) at depths of −5,600 to −5,800 m, followed by 304 samples at −5,800 to −6,000 m (10%). The southern histogram has a bimodal distribution with two peaks: 523 samples (20%) with depths of −5,800 to −6,000 m. The second peak (10%) is on the Bonin Ridge. The GMT proved to be an effective instrument for marine geological mapping, 3D and 2D modelling, statistical analysis and graphical plotting.

What determines foreign direct investment in Russia?
Authors: Gurshev Oleg
Published: July 2020

This article focuses on the determinants of inward foreign direct investment (FDI) in Russia. The article briefly describes the historical context of foreign investment policymaking in Russia since the beginning of the economic transition to an open market economy after the dissolution of the Soviet Union. When compared to other developing countries, Russia's FDI stocks continue to lag despite a set of proactive measures undertaken by the national government. Following the literature review, the most commonly cited determinants explaining inward FDI in Russia include market size, labour productivity, trade and investment barriers, domestic exchange rate, rule of law and institutional framework.

This article aims to contribute empirically to the study of determinants of inward FDI in Russia.

This article uses the Pseudo-Poisson Maximum Likelihood (PPML) estimation technique, the robustness of the PPML estimation is then verified using a standard autoregressive integrated moving average (ARIMA) model with the Durbin–Watson autocorrelation test.

Our benchmark results suggest the efficiency-seeking motive of FDI over a market seeking and horizontal motive as a main reason for inward FDI in Russia. The ARIMA regression indicates the absence of statistical significance of economic openness and variables of labour productivity. Overall, the market size and tax rate variables have the most positive effects on the inward FDI, while barriers to trade and sanctions have the most negative effects. The results confirm that for transitional economies, integration into the world economy, proactive local development and tax cuts for outside investors remain to be critical when it comes to attracting FDI.

Published: July 2020

Apis mellifera L. is an essential pollinator that is currently being affected by several stressors that disturb their ecological function and produce colony losses. Colonies are being seriously affected by the ectoparasitic mite Varroa destructor. The relationship between stressors and bee symbionts is being studied in order to enhance bee health. The goal of this study was to evaluate the effect of cell-free supernatants (CFSs) produced by Lactobacillus johnsonii AJ5, Enterococcus faecium SM21 and Bacillus subtilis subsp. subtilis Mori2 on A. mellifera nutritional parameters and their toxicity against V. destructor. Toxicity and survival bioassays were conducted on adult bees with different concentrations of CFSs. Nutritional parameters such as soluble proteins and fat bodies in abdomens were measured. Varroa destructor toxicity was analyzed by a contact exposure method and via bee hemolymph. At low concentrations, two of CFSs tends to enhance bee survival. Remarkably fat bodies maintained their levels with all CFS concentrations in the abdomens, and soluble protein increased at a high concentration of two CFSs. Toxicity against V. destructor was observed only via hemolymph, and results were in agreement with the treatment that produced an increase in bee proteins. Finally, CFS produced by L. johnsonii AJ5 could be a promising natural alternative for strengthening bee health.

Published: July 2020

Beekeepers need to establish migratory apiaries to benefit from pollen and nectar source plants as in order to increase honey yield. Thus, following the flowering seasons of honey source plants has vital importance when deciding the route of migration. In this study, MODIS imagery was used to generate weekly NDVI data between 1st April to 31st August 2018, when beekeeping activities start and end in the study area. Although MODIS images have high temporal resolution, low spatial resolution (250 meters) makes them insufficient when deciding the crop types and plants. While detecting plants in natural plant areas requires high spatial resolution NDVI, Crop Coverage Registration System (CCRS) parcel-based crop coverage records can enrich the NDVI data without increasing spatial resolution in agricultural lands. Thus, the CCRS data were integrated with NDVI images for migratory beekeeping in agricultural areas as an innovation. To generate both high temporal and spatial resolution, NDVI and CCRS data were integrated together with a beekeeping suitability map to generate the apiary schedule. The results were verified with 176 existing apiary locations and production dates retrieved from field studies which revealed the existence of three seasons in the study area as early and late apiaries (in natural plant areas) and apiaries in agricultural lands. Accuracy analysis showed that 82% of the apiaries intersected with suitable locations and that apiaries in agricultural areas were detected five days earlier than in field studies and obtained more accurately than natural plant apiaries.

Published: July 2020

Dilated cardiomyopathy (DCM) is the most common type of cardiomyopathy in children. Heart transplantation is considered standard therapy in dilated cardiomyopathy with end-stage heart failure. We present a case of a 15-year-old patient diagnosed with DCM in the neonatal period, who underwent heart transplantation for end-stage heart failure. Despite the use of induction therapy, the endomyocardial biopsy performed at two weeks post-transplant revealed mixed moderate cellular (2R) and humoral (pAMR2) allograft rejection. Aggressive rejection treatment was initiated with good outcome. Besides endomyocardial biopsy, advanced echocardiography can also be a valuable noninvasive tool for rejection assessment.

How to Improve Communication within an Organization? The Relationship between Cultural Intelligence and Language Competence
Authors: Jurásek Miroslav , Potocký Tomislav
Published: July 2020

Objective: This article deals with the effective functioning of an organization in the international context. It focuses on the two key aspects of the communication in this respects: cultural intelligence (CQ), the capacity to operate successfully in the multicultural setting, and the quality of internal communication; it is investigated whether CQ (and its components: metacognitive, cognitive, motivational and behavioural) are rather related to the number of foreign languages or the language proficiency a person (or an employee) knows (has).

Methodology: The sample of 132 undergraduate students of the English and Czech study programs at one private business university in the Czech Republic was used. The Spearman correlation coefficient, Chi–Square test for independence and the one–way ANOVA test (all of them conducted in the statistical program IBM SPSS Statistics 21) are calculated in the paper.

Findings: CQ depends on the quality (the level of proficiency) rather than the quantity (the number) of foreign language skills. This conclusion applies regardless of gender: our data did not confirm that language skills were gender-dependent.

Value Added: Recently a very fashionable cultural intelligence (CQ) construct has been explored in relation to a variety of variables and outputs. Nevertheless, insufficient attention has been given to the relationship between cultural intelligence and language competence so far; moreover, the research has brought contradictory results up to now. This study fills the actual knowledge gap.

Recommendations: It is shown that in terms of the effective functioning in a culturally unknown environment and with a restricted time to learn foreign languages, it is preferable to develop continuously one´s skills in lingua franca than parallel and more superficial studies of several languages.
Quality of Family Life and Workplace Deviant Behaviour with Perceived Competence as a Mediator among University Staff
Authors: Fagbenro Dare A. , Olasupo Mathew O.
Published: July 2020

Several studies have found a variety of factors as antecedents of deviant behaviour but the role of family life on workplace deviant behaviour, as well as the mediating role of perceived competence in the quality of family life-deviant behaviour relationship, have received little study. This study examines the mediating effect of perceived competence on the relationship between the quality of family life and work-deviant behaviour. The study adopted the wellness model and self-determination theory as theoretical standpoints. Three hundred and eight-four (384) university staff in Nigeria participated in the study. Results revealed that there was a significant negative relationship between the quality of family life and workplace deviant behaviour. The result of the hierarchical multiple regression also revealed that perceived competence mediates the link between the quality of family life and workplace deviant behaviour. These findings suggest that psychologists should design training programmes aimed at improving the sense of competence and quality of family life, which invariably will reduce workplace deviant behaviour.

Published: July 2020

The continuous monitoring of 222Rn activity concentration, CO2 concentration, and microclimatologic parameters (internal air temperature and relative humidity) in the Važecká Cave (Northern Slovakia) is being carried out at three monitoring stations, namely, Gallery, Lake Hall, and Entrance Hall. Radon activity concentration and CO2 concentration exhibited a clear annual variation. The daily average of radon concentration ranged 1300–27 700 Bq/m3 at the Lake Hall station and 3600–42 200 Bq/m3 at the Gallery station. Radon reached its maximum in the summer months, from June to September. The annual maximum of CO2 concentration is registered approximately one month later than radon maximum. The annual variation of radon and CO2 is controlled by the seasonal change of ventilation regime associated with the seasonal variation of the difference between the temperature measured inside the cave and the atmospheric temperature.

Published: July 2020

Antimicrobial peptides are natural substances that have played a role in the development of the adaptive immune system, and are currently involved in the prevention of infections, through their direct antimicrobial and immunomodulatory properties. While the amino acid composition and spatial structure vary, most antibacterial peptides have a positive surface charge, which allows them to bind to the negative bacterial membranes. Buforin II is a widely studied antimicrobial peptide first obtained through the structural modification of buforin I, a peptide isolated from Bufo gargarizans. The peptide showed significant antibacterial activity against Gram-positive and Gram-negative bacterial strains. The mechanism of action of buforin II differs from that of other antimicrobial peptides, as it binds directly to bacterial DNA and RNA. The aim of our study was to obtain recombinant buforin II with a ubiquitin fusion partner, through heterologous expression in Escherichia coli Rosetta™ (DE3)pLysS cells, using a laboratory scale bioreactor. The incubation of expression host cells in a bioreactor allowed the constant monitoring and control of the process parameters, leading to high biomass levels and an increased production rate of the peptide. The parameters used during incubation were: 37°C, pH=6.9 and dissolved oxygen level above 40%. Purification of the recombinant protein was accomplished by affinity chromatography using a Ni-chelate solid phase to which the 10xHistag of our construct showed affinity. Method optimisation consisted in the use of gradient and linear elution, of which the latter was found to be more effective. Digestion of the fusion partner from the target peptide was performed with ubiquitin carboxyl-terminal hydrolase enzyme. The expression and purification protocols developed in our experiment allow the production of a significant amount of buforin II, allowing its use for further research. Furthermore, the presented methods could be suitable for industrial production of the recombinant peptide..

Authors: Malá L. , Laloučková K. , Hovorková P. , Skřivanová E.
Published: July 2020

Medium-chain fatty acids (MCFAs) and their monoesters were tested for their antibacterial activity against the Gram-negative pathogen Aeromonas hydrophila. The antimicrobial effect was evaluated at two temperatures (4 °C and 37 °C) using a standardized microdilution method in a 96-well microtitration plate. The minimum inhibitory concentrations of selected MCFAs were determined as the lowest concentration limiting the growth of A. hydrophila in wells compared to a positive control of ≥ 80%. The results indicated that the most effective compound against A. hydrophila was sucrose monocaprate after incubation at 37 °C (0.625 mg ml−1), whereas monocaprylin was the most effective compound after incubation at 4 °C (1.25 mg ml−1). Free MCFAs showed no antibacterial effects towards this bacterium. Low solubility and sensory properties could limit the use of fatty acids in aquatic environment, which should be the subject of further studies.

Hypertension is a major health problem and it accounts for more than 9.4 million people to die every year globally due to its high complications. It is a major risk factor for cardiovascular diseases and high research importance has been given due to its high prevalence. The objective of the present study was to determine the prevalence of hypertension and to assess its risk factors among monks populations in Thimphu. A cross-sectional study with purposive sampling method was conducted among the five different monasteries in Thimphu. A self administered questionnaire was structured for 307 monks from age 18 and above. The prevalence rate of hypertension in the present study was 32.6% among Bhutanese monks. Hypertension is significantly higher in elder age groups which conclude that hypertension increase with the increase of age and have a strong association. Alcohol use, betel consumption, and physical inactivity were found to be significant risk factors for developing hypertension. With the 32.6% prevalence rate, only 26% of them are receiving medications. There is an impending need for effective intervention strategies.

Abstract: (Photo)electrochemical processes are involved in many fields of science and technology. The use of spectroscopic techniques coupled to (photo)electrochemistry, are mandatory to get information about interfacial processes on scale ranges from millimeters to the nanoscale. The development of spectroelectrochemical cells (SEC) contribute to the progress of the field of (photo)electrochemistry and its impact in science and technology. Therefore, in this work, we describe in detail the development of a versatile SEC that can be used for several in situ techniques. We performed electrochemical and computational experiments to analyze the response of our SEC as a function of the working electrode size, position and distance to the window. We found that our SEC behaves as the conventional cell when the electrode is far from the window. However, important differences arise in the thin layer configuration. The computational experiments suggest that to mitigate these problems, it is important to perform in situ experiments in the thin layer configuration using electrodes as small as possible.

Silver ions, the most toxic form of silver, can be present in drinking water due to their release from silver nanoparticles which are widely used in consumer products. Due to their adverse health effects, a quick portable approach for detection in drinking water is needed. Herein we report on the development of an electrochemical sensor for silver ions detection in tap water using linear sweep voltammetry with in situ pH control; enabled by closely space interdigitated electrode arrays. The in situ pH control approach, allows the pH of a test solution to be tailored to pH 3 thereby eliminating the current need for acid addition. A calibration curve between 0.2 - 10 µM was established for silver detection in sodium acetate when 1.25 V and 1.65 V was applied at the protonator electrode during deposition and stripping, respectively, as a proof of concept study. For the final application in tap water, 1.65 V was applied at the protonator electrode during deposition and stripping. The chlorine ions, present in tap water as a consequence of the disinfection process, facilitated the silver detection and no additional electrolyte had to be added. Combination of complexation of silver ions with chlorine coupled with in situ pH control resulted in linear calibration range between 0.25 and 2 µM in tap water without the need for acidification.
Maps of light pollution in odd places

Advances in remote sensing have proved to be highly valuable for the light pollution research and awareness raising. Maps based on night time satellite data can be used in communication campaigns aimed to improve the public and policy awareness about the extent and effects of light pollution and to justify appropriate management actions. However, visually appealing maps are also used in other communication settings. This article reviews different uses of light pollution maps and discusses the societal implications such uses. Based on examples of light pollution maps in different communication settings not directly related to light pollution debate the review proposes that the relatively wide popularity of light pollution maps may strengthen the impressions of artificially illuminated night environment as the normal baseline for human experience. This contributes to the loss of experience of the natural darkness possibly leading to generational amnesia complicating the management of light pollution. Multiple uses of light pollution maps and other visualizations should be taken into account when campaigns and policies aimed to support sustainable lighting are planned and implemented.

The objective of this study was to assess the udder health in lame dairy cows. The study was performed on 35 dairy cows which were admitted to the Clinic of Ruminants. The most frequent claw diseases were white line abscess (28.6%) and toe necrosis (28.6%), followed by digital dermatitis (17.1%), toe ulcers (14.3%), and sole ulcers (11.4%). The prevalence of mastitis in lame cows was 74.3% (26); clinical mastitis was detected in 5 (19.2%) and subclinical mastitis in 21 (80.8%) dairy cows. Distribution of mastitis was similar in terms of front (52.54%) and rear quarters (47.46%). For statistical analyses of mastitis grade in lame dairy cows, a six-point Mastitis Score was created based on physical examination of the mammary gland and results of California Mastitis Test. The Mastitis Score tended to be higher in cows with corium inflammation than in those with digital dermatitis (10.0 and 6.5, respectively). Microbiological culture of 24 positive milk samples was performed and intra-mammary pathogens were isolated in 18 (75%) samples. The most prevalent bacteria were coagulase negative staphylococci (50%), followed by Enterococcus spp. (16.7%), Proteus spp. (11.1%), and Aerococcus viridians (11.1%). Of the total bacteria, contagious pathogens were determined in two milk samples (11.1%). In conclusion, high prevalence of mastitis was detected in lame cows suffering from claw diseases without a significant effect of the type of claw diseases on the mastitis grade. Moreover, the dominating isolation of environmental pathogens may be a result of longer lying period of animals affected with lameness.

Published: July 2020

The current behaviour of Small and Medium Enterprises has to face many problems and the survey are predicted, 47 per cent of Small and Medium Enterprises stop trying. One of the causes is that there are still many small and medium businesses, from the beginning of opening their business up to now, they have never carried out an analysis of profit and loss calculations and a comprehensive calculation of how many product units should be made so that the business returns on capital by looking at production factors or resources used. Break-even analysis is a financial tool that helps decide at what stage a company, or new service or product, will be profitable, which is a financial calculation to decide the number of products or services that a company must sell to cover its costs (especially fixed costs). This research paper is the application of the theoretical concepts of CVP Analysis, Break-Even Point a powerful tool for planning and decision making. highlight costs, quantities sold and prices, which are the company's financial information.
