En este artículo se utilizaron las fotos georreferenciadas, compartidas por usuarios de la red “Panoramio” entre 2007 y 2014, como un proxy para analizar la distribución espacial y temporal de los visitantes, en la ciudad de Lisboa. El conjunto total de datos (> 75.000 fotografías) fue segmentado en turistas y locales, con base en las marcas temporales, resultando una muestra de 17.604 fotos tomadas por > 5.000 usuarios. La evidencia empírica sugiere que la distribución espacial de los visitantes no es homogénea. Además, exploramos la relación espacial entre el patrón observado (la aglomeración geográfica de visitantes) y un conjunto de 24 variables asociadas a la oferta turística de la ciudad. A través del análisis de regresión lineal múltiple, se verificó que son los “monumentos de interés público”, los elementos que presentan mayor atractivo, considerando los factores explicativos seleccionados, y que existen áreas del centro histórico cuyo potencial turístico está subestimado.
Reproducibilidad científica: ¿Qué es y por qué debemos interesarnos en geo-ciencias?
Authors: Ballari Daniela
Published: August 2019

A pesar de que en los últimos tiempos se ha resaltado la importancia de la reproducibilidad como pilar del proceso científico, en las geo-ciencias ésta no ha sido reconocida como una preocupación inminente. Esto no es por ausencia del problema, sino por falta de evidencias que así lo demuestren. Es por ello que la comunidad científica internacional, entre ellas la relacionada con las geo-ciencias, está promoviendo el posicionamiento de la problemática y generando evidencias y propuestas que permitan superar la llamada “crisis de reproducibilidad”. Así, el objetivo de este documento es aportar al avance de la discusión de la reproducibilidad científica en la comunidad científica y académica Latinoamericana de las geo-ciencias, como forma de abrir el debate crítico y propositivo sobre estrategias para mejorar la reproducibilidad de nuestras investigaciones.

The bacteria of the Cutibacterium (formerly Propionibacterium) acnes species are representatives of normal microbiota of human skin on the one hand and they contribute to the development of inflammatory processes, such as acne, infectious complications in the post-traumatic and postoperative period of the eye (endophthalmitis), the cardiovascular system (endocarditis), central nervous system and musculoskeletal system (osteomyelitis), implant-associated infections on the other hand. To identify epidemically significant genotypes with high pathogenetic potential and genotypes of low pathogenic commensals the different molecular genetic approaches are used. The whole genome sequencing of C. acnes A1-14 strain isolated from the large intestine of a healthy person was carried out for the first time. As a result of alignment and collection, the nucleotide sequence of the genome was 2,484,560 pairs of nucleotides.The strain belongs to a phylotype II, a ribotype 6 and sequence-type 7 (McDowell A. et al. scheme) or 73 (Lomholt H. B., Kilian M. scheme) according to the results of genotyping. We showed that there are no mobile elements, determinants of pathogenicity and antibiotic resistance, mutations in the 16S rRNA, 23S rRNA, gyrA, gyrB, parC, parE genes and established the presence of CRISPR-Cas structure in the genome of C. acnes A1-14. An extrachromosomal sequence belonging to the genome of the Syphoviridae family bacteriophage was found. The morphological characteristic of the bacteriophage virion, the presence of that as extrachromosomal structure is typical to many C. acnes strains, is given using the electronic microscopic method of research. Thus, the obtained in our study results complement the understanding of the molecular genetic features of C. acnes strains isolated from various human biotopes and which are symbiotic microbiota representatives.

Published: August 2019

Hepatitis A is a common cause of viral hepatitis. The pronounced autonomy of the epidemic process of infection, the polymorphism of its clinical symptoms and other factors make it difficult to apply universal approaches to predict the morbidity of hepatitis A. The aim of the study was to develop a complex approach for epidemiological risk assessment of hepatitis A. Short-term prediction of hepatitis occurrence rate was carried out with maximum stability and regression equation methods in Nizhny Novgorod during the 1994–2017 period. Concentration of the pathogen in waste water samples was made by adsorption method using non-woven bags with macroporous glass. Viral RNA was detected by real-time PCR method. Anti-HAV IgG prevalence rate was studied by ELISA (enzyme-linked immunosorbent assay) method among the relatively healthy population in the age from 1 to 60 years in Nizhny Novgorod. Accuracy of mathematic prediction of hepatitis A morbidity rate has been ineffective in the current conditions. It is necessary to supplement the analysis of recorded morbidity data by monitoring the activity of activation signs of the pathogen circulation and parameters of specific population immunity for an adequate assessment of the epidemiological risk of hepatitis A in current conditions. Such precursors are an increase in the detection rate of anti-HAV above a threshold value in the indicator age groups of children 1–4 years old and 5–9 years old, as well as the detection of pathogen RNA in wastewater before treatment.
Mineral Resources Potential of Vietnam and Current State of Mining Activity
Authors: Khoi Nguyen Ngoc
Published: August 2019

Vietnam, with an area of 331,210 km2, occupies the eastern side of the Indochina peninsula. It forms a narrow (locally only 40-70 km)band of land, extending over 1,500 km along the East Sea (South China Sea). Vietnam is constituted mainly by the folded belts surrounding two shields, cratonised in the Upper Proterozoic: the Yangtze craton and the Indochina shield, located in the Mekongbasin and occupying most of Cambodia and the contiguous parts of Laos and Vietnam. The folding occurred during the lateHercynian (early Triassic) orogenic movements, active mainly in the central and southern Vietnam and the Indosinian(late Triassic, anteNorian) orogeny. Various geological surveys have indicated that Vietnam is well endowed with a wide rangeof mineral resources. The country has some of the world's biggest resources of phosphate (apatite),bauxites, rare earths, and large, commercially viable deposits of oil, coal, gold, gemstones, copper, zinc,tin, chromite, manganese, titanium (mineral sands), graphite and other minerals. At present, Vietnam produces approximately 3.5 million tons of crude oil/year and its mineralproduction includes: coal (about 10.7 million tonsa-1), cement (1.6 million tons), phosphate (300,000 tons), chromite (3.5 million tons), iron ores, gold (around 1,000 kg, including production by the local population), cassiterite (3,000 tons), graphite,kaolin and many other minerals produced to serve domestic demand. Several foreign companies are involved in oil exploration (BP, Total, BHP) as well as in prospecting (seldom in exploitation) for minerals (mainly Australian companies). In spite of the current mineral production, the country’s mining sector is still under-developed and many available mineral resources remain unexploited. Nevertheless, this situation is changing. The recent but increasing level of involvement of foreign companies in the Vietnamese mineral sector will accelerate the development of high value and/or export-orientated minerals, especially as some of the neighboring countries (China, Japan, South Korea ...) lack many mineral resources. And the developing Vietnamese economy will surely entail mining of various minerals for the domestic use.

Overall, mining projects make a significant contribution to gross of domestic product (GDP) in Lao People’s Democratic Republic (Lao PDR). Benefits include increased export revenues, provision of royalty and tax income to the government, technology transfer, worker training and the creation of a skilled workforce. This can also lead to improved social, physical, legal and financial infrastructure due to development around the mining areas such as roads, electricity and water distribution. Managed properly, economic benefits from mining projects can benefit future generations,even after operations have ceased. For Lao PDR, rapid expansion of the mining sector is seen as vital to economic development. In the National Socio-Economic Development Plan, mining was prioritized as a key sector to help Lao PDR achieve its goal to graduate from its status as least developed country by 2020. Government revenues from mining projects are a major contributor to the country’s National Growth and Poverty Eradication Strategy. Environmental management and monitoring of the operations of mining projects are essential in order to identify and mitigate potential negative environmental impacts. Such impacts may be minimized through the use of mining industry best practice as well as compliance with Government of Laos (GoL) and international environmental standards and regulations. The environmental management and monitoring process first identifies and quantifies potential impacts of a mine’s operation on land, water, atmospheric and biological resources, as well as on human settlements. Secondly,measures are proposed to avoid or mitigate identified adverse impacts, including a specific requirement for a mine closure and rehabilitation plan.

Passenger exposure to volatile organic compounds (VOCs) emitted from vehicle interiors hasincreasingly drawn public concern over their potential health risks. This study aimed to investigate ambient levels of in-cabin VOCs in a new car over the period of one year after first delivery. The relationship between VOC concentrations and in-cabin temperature was also studied. Seventeen active air samplings inside a parked new car were conducted from February 2012 to February 2013 using sorbent tubes. Six VOCs were measured with first-month average concentrations of 215 μgm-3for benzene, 65.6 μgm-3for toluene, 151 μgm-3for 1,2,3-trimethylbenzene, 806 μgm-3for ethyl acetate, 183 μgm-3for formaldehyde, and 28.2 μgm-3for acetone. The concentration profiles of all VOCs except formaldehyde declined, falling below the detection limits towards theend of the 1-year monitoring period. Formaldehyde concentrations were found to be directly proportional to in-cabin temperature at a significance level of p=0.05 during the first five months.

The effects of ethylenediaminetetraacetic acid (EDTA) and diethylene triaminepentaacetic acid (DTPA) on cadmium (Cd) uptake by water hyacinth (Eichhornia crassipes) in Cd-contaminated soilwas studied. Experimental samples were separated into 4 treatment groups: 1) Untreated control, 2) EDTA addition, 3) DTPA addition, and 4) mixture of EDTA and DTPA (1:1) addition. The plants were harvested at 20, 40, 60, 80 and 100 days. Cd levels were measured in soil samples, water samples and two parts of the plant: shoot (stem and leaves) and root. The results showed that Cd accumulation in plants with added EDTA and DTPA were higher than the control set, indicating that EDTA and DTPA addition increased Cd uptake by water hyacinth. Cd accumulations in the root in all groups were significantly (p<0.05) higher than that in the shoot. In EDTA added sets, Cd accumulation in the root was higher than in shoots and were measured at 160.91 and 13.37 mg kg-1at 100 d, respectively. This research indicates that DTPA was most suitable for increasing the cadmium removal capacity of water hyacinth and offers a suitable phytoremediation technique to help clean contaminated sites.

The effects of organic fertilizer on Cd phytoavailability and distribution in rice plants(Oryza sativaL.) were examined in pot and field experiments. The results of the pot experiment show that the addition of organic fertilizer increased the oxidizable Cd fraction(F3) and decreased the soluble and exchangeable Cd fraction (F1). There was also an increase in the dry matter yield when more organic fertilizer was applied. The Cd concentrations in the rice plant parts were observed in the following order: root > stem > grain. The accumulation index from the field experiment indicates that organic fertilizer application is likely to reducethe uptake of both Cd and Zn by rice.

Authors: Diayi Anslem , Gbadebo Michael
Published: August 2019

From depths of 0-5 cm, 5-10 cm and 10-15 cm, sediment samples were collected from three locations in the lower region of the Ogun River Basin, namely Mokoloki, Oke-Oko and Kara. The samples were obtained using Van Veen sediment grab after which they were stored in well labeled polythene bags for onward transportation to the laboratory. For pH and conductivity, samples were determined in-situ using standard methods by the American Public Health Association of 1992 while Organic Carbon was determined by the Wakley Method. The sediments were then air dried before analysis for particle size and metal concentration. Induced Couple Plasma Mass Spectrometry (ICP/MS) was used to determine metal concentrations. Data obtained were used to determine the geochemical pollution intensities for the various sediment samples. The results of physicochemical analyses revealed all sediment samples to be alkaline, while particle size analysis showed that the sediments were sandy. All metal concentrations for Cu, Pb, As, Zn, Hg, Cd, and Cr were lower than the Environment Canada Sediment Quality Guideline standards of 35.70 ppm, 35.00 ppm, 0.60 ppm, 123.00 ppm, 5.90 ppm, 0.17 ppm and 37.50 ppm, respectively. The low metal concen-trationsobtained from the trace metal analyses were confirmed with an ‘unpolluted status’ obtained for all sediment samples analyzed using the geochemical accumulation index formula. Results showed that metal concentrations in these areas are low and do not pose a threat to the survival of living organisms living in sediments or the surrounding environment.
