Ontologia se refere a um conjunto de conceitos fundamentais e relações, capaz de identificar como as pessoas interpretam a situação. No domínio de gerenciamento de risco, a ontologia propicia no desenvolvimento de modelos de inferência que auxiliam na percepção e construção de melhor tomada de decisão em situações críticas, principalmente quando se relacionam em áreas que envolvem vidas humanas, meio ambiente e patrimônio. Entretanto, formas de avaliar as características das classes, propriedades, axiomas, eficiência e objetividade das ontologias são necessárias para garantir uma melhor representatividade da informação, e também, se está cumprindo com o compromisso ontológico e transparecendo de forma clara as informações relacionadas ao domínio a que pertence.  Este artigo tem como objetivo apresentar o processo de avaliação da ontologia human-driven brazilian crime ontology, com intuito de averiguar o cumprimento de seus objetivos relacionados ao domínio criminal, especificamente na construção semântica de situações de crimes, no caso, roubo e furto.

The mining activity has left mine tailings with high quantities of heavy metals and metalloids. Due their extreme toxicity, they represent a hostile environment for microbial colonization; however, there are metalotolerant bacteria in these mining wastes, and this is attributed to mechanisms of bioaccumulation and biotransformation of metals. The native bacteria from El Fraile mine tailings have developed adaptation mechanisms that allow them to persist in a toxic environment, thus, the objective of this study was to isolate and identify bacteria with the ability to tolerate, bioaccumulate or biotransform heavy metals. Our study was based on descriptive observations, we isolated 141 strains from water, leachate, soil, and rhizosphere and stems of plants from El Fraile mine tailings, Guerrero, Mexico. Bacterial tolerance was determined by the minimum inhibitory concentration in different metallic salts, the capacity of bioaccumulation of Ag, Pb, Cr, and Cd, and by the biotransformation of As (III) and Cr6+; in addition, representative bacteria were identified using 16S rRNA gene sequences. The results of the 141 strains analyzed showed ascending tolerance to Cd2+ 2 mM, Cu2+ 5 mM, Pb2+ 9 mM, Zn2+ 9 mM, Ag2+ 10 mM, As3+ 30 mM, and As5+ 45 mM. Only 9.24 and 39% of the strains bioaccumulated Zn2+, Pb2+ and Ag2+. In regard to biotransformation, 9% oxidized As3+ to As5+, and 7 and 24% reduced As5+ to As3+ and Cr6+ to Cr3+, respectively. The genera that prevailed were Chryseobacterium sp., Staphyloccoccus sp., Stenotrophomonas sp., Acinetobacter sp., Bacillus sp., Serratia sp., and Enterobacter sp. These results showed that in El Fraile mine tailings, there are bacterial strains capable of bioaccumulating and biotransforming heavy metals and metalloids; therefore, further studies must be conducted to know their potential in the processes of bioremediation of areas polluted with metals.

Changes in the land use of a basin area affects the infiltration and surface water runoff directly, altering the balance of the hydrological cycle. Therefore, estimating parameters of water infiltration and runoff for each type of land use and vegetation (USV) is fundamental to differentiate the impact caused by a change of land use over the hydrical balance of a given area. The objective of this study was to estimate cumulative inf iltration (F), basic inf iltration rate (Ti), constant inf iltration rate (fc) and inf iltration decay coeff icient (k); as well as inf iltration and runoff coefficients in mountainous cloud forest (BMM), (SMSPC), pine-oak forest (BPQ), oak forest (BQ), induced grassland (PI), pine forest (BP), agricultural land in use (TC) and fallowed agricultural land (TCD). Thirty-eight simulated rain experiments were carried out at an average intensity of 100 mm h-1 with a hand-portable single nozzle rainfall simulator. The exponential model was employed to estimate fc and k and the Horton semi-empirical model to estimate Ti and F. The analysis of variance was performed by the generalized linear model (GML) to evaluate the effects of USV and texture type, and the analysis of covariance was employed to determine the effects of slope, mulch depth, organic matter % of total variability content, sand, mud and clay content, and bulk density. The exponential model fitted more than 80% of total variability (R2) at all USV. Agricultural land in use and TCD showed the lowest F and Ti and the highest k (P < 0.001), BMM exhibited the highest infiltration capacity (F) and lowest decay rate (k). The bulk density of the soil, and content of mud and organic matter were the variables positively associated to infiltration (P < 0.01).

In the spring-summer agricultural cycle of 2016, the hybrids P4082W, H565, and DK357 were evaluated with chemical and chemical + biological fertilization by means of a factorial experiment arranged in a split-plot design. In the treatments with biofertilizer the seed was inoculated with Glomus intraradices + Azospirillum brasilense; in chemical fertilization 120N-80P-80K was applied. The response variables measured were: height, diameter of the neck and number of leaves of the plant, number and weight of ears with and without bracts, weight of bracts, length and diameter of the ear, number of rows ear-1, grain weight of 5 ears of cobs, length, diameter and weight of the cobs, grain yield, fodder and dried grinding. To determine the profitability of the systems, the total cost (TC), total income (IT), and net income (IN) were calculated, and finally the gain by invested MXN peso (GIP). The statistical analysis included analysis of variance and test of comparisons of means by the Tukey method. It was found that the hybrid DK357 recorded the highest height, number of leaves, grain weight, length of ear and cob, yield of grain and forage, both “zacateado” and dried milled. The P4082W genotype obtained the highest weight of ear with and without bracts. The chemical fertilization favored the yield of forage zacateado, and in combination with the biological treatment, increased the yield of grain. The DK357 and P4082W hybrids grown with chemical and biological fertilization turned out to be profitable in the systems for the production of grain alone, forage grass and grain, and ground dried fodder.

The effect of homeopathic medicines on germination and initial growth of Salicornia bigelovii (Torr.) was evaluated under controlled conditions. A completely randomized experimental design was applied with three homeopathic treatments, Natrum muriaticum 7CH (NaM-7CH); Phosphoricum acidum 13CH (PhA-13CH); Natrum muriaticum 31CH (NaM-31CH); distilled water as control (AD) and six replicates per treatment. The response variables were the percentage and germination rate, stem and radicle length, and fresh and dry biomass of aerial and radicle parts. An analysis of variance and subsequent tests were performed to compare means (Tukey HSD, P ≤ 0.05) when a significant difference between treatments was found. A significant increase was observed in all the response variables evaluated in all the homeopathic treatments with respect to control (AD). The variables with the highest response were germination percentage, with values up to 44% and stem and radicle length with 35% above the control treatment in plants treated with NaM-7CH. These results confirmed the positive effect of homeopathic medicines on germination and initial growth of S. bigelovii, revealing that agricultural homeopathy, particularly NaM-7CH, PhA-13CH and NaM-31CH treatments, is a viable alternative to optimize the cultivation of species since it increases germination percentage and stimulates initial growth.

The response of Phaseolus vulgaris L. variety Quivican to the application of homeopathic medicines as growth promoters was assessed during its initial plant development. A completely randomized experimental design was applied with three homeopathic treatments: TH1 [MgM-31CH (Magnesium metallicum 31 CH)], TH2 [MaMnP-3CH (Magnesium-Manganum phosphoricum)], TH3 [TH1 + TH2), and distilled water as Control group. The analyses showed the best results in the plants that received TH3 with a significant increase (P ≤ 0.05) with respect to the control group in the following response variables: length of stem (47.14%) and root  (30.27%); biomass of fresh root (13.57%), leaves (68.36%) and stem (11.88%); dry biomass of leaves (84.72%) and stem (36.11%); leaf area (21.74%), stem diameter (39.54%) and number of leaves (16.66%). These results confirm that agricultural homeopathy is an eco-friendly and technologically viable alternative for bean cultivation because it stimulates growth, which allows obtaining more vigorous plants with greater productive potential and less dependent on agrochemicals. Because homeopathic medicines are harmless, the balance of the agroecosystem is also improved, achieving a positive impact in the short, medium and long term besides their application in conventional and organic agricultural production.

The application of bioactive substances in a minimum dose is an alternative to reduce the application of harmful agrochemicals in agriculture, particularly vegetables. The objective of this research was to evaluate the effect of four homeopathic medicines during germination, emergence, and vegetative development of cucumber plants (Cucumis sativus L.). The experimental design included two centesimal homeopathic dynamizations (7CH and 13CH) of Silicea terra (SiT), Natrum muriaticum (NaM), Magnesia phosphorica (MaP), and Arsenicum album (ArA) and a control (water) treatment. A completely randomized 2 × 4 + 1 block design was used in three repetitions. The variables evaluated were rate and percentages of germination and emergence, stem and radicle length, and fresh and dry weight of the aerial part and radicle. Additionally, during the vegetative development the diameter of the stem and the number of leaves and flowers were evaluated. With ArA-13CH, significant differences in germination were observed (53.33%) and with NaM-13CH longer stem length (107.07 cm) during vegetative development, compared to the control group (78.63 cm). Radicle length showed significant differences with the application of SiT-7CH (49.59 cm) compared to the control group (28.6 cm). During germination the best result in the radicle fresh and dry weight was recorded when applying ArA-13CH. In emergence, the greatest fresh radicle weight was obtained with MaP-13CH, and the largest stem diameter, number of leaves and number of flowers were obtained with NaM. The results obtained confirmed that the evaluated homeopathic medicines positively affected the initial stage and vegetative development of cucumber (Cucumis sativus L.) under controlled conditions. This research represents an advance in agricultural homeopathy for the sustainable management of vegetable cultivation.

The production of the turnip (Brassica napus L.) in Ecuador, depends largely on the use of agrochemicals, whose indiscriminate use causes negative effects on the environment. Agricultural homeopathy has emerged as an ecological alternative to improve the health status of plants. In order to help improve the sustainable production of vegetables, the effect of two centesimal dynamics (7CH and 31CH) of three homeopathic medicines for human use was evaluated: Silicea terra (SiT), Natrum muriaticum (NaM) and Phosphoricum acidum (PhA ), on the germination, emergence and vegetative development of B. napus plants, applying a completely randomized 2×3+1 block design with three repetitions for the three stages of the crop. The variables evaluated during germination and emergence were: percentage of germination and emergence, length of stem and radicle, fresh weight of the aerial part and radicle, dry weight of the aerial part and radicle. The variables evaluated during vegetative development were: plant height, stem diameter, number of leaves, weight, leaf area and productive yield. Signif icant differences were recorded in all the variables and stages of development studied. The highest germination values corresponded to SiT-7CH and PhA-7CH (100%), surpassing the control group (83.5%). The PhA-7CH and NaM-31CH treatments stimulated stem growth in the germination stage (3.40 cm) and NaM-7CH root growth (4.07 cm) in the emergence stage. During the vegetative development, the plants with the highest production were those treated with NaM-7CH. The highest prof itability of the crop (71.33%), with a benef it / cost ratio of 1.7% was obtained with SiT-7CH. The results obtained suggest that agricultural homeopathy has potential in horticulture, since all treatments favorably influenced the response variables during germination, emergence and vegetative development of (Brassica napus L.).

Soil salinity is a global problem that increases year by year in arid and semi-arid regions, including Mexico where the distribution and extension of salinized soils reduces productivity and causes severe damage to different cultivated species. Homeopathic medicine is compatible with traditional, ecologic, and organic agriculture, and it can increase tolerance to salinity stress conditions and improve soil-plant ratio. Chiltepin chili (Capsicum annuum L. var. glabriusculum) is a species of high commercial value in northern Mexico affected by soil salinity. Thus, the objective of this study was to assess the eff iciency of Natrum muriaticum (NaM) homeopathic medicine for human use, to mitigate NaCl stress in chiltepin chili established in a hydroponic system and subjected to different NaCl concentrations. A completely randomized design (2A × 3B) with factorial arrangement was used with four replicates of nine plants each. The plants were subjected to two NaCl (0 and 200 mM) concentrations, two centesimal NaM (7CH and 13CH) of NaM (NaM-7CH and NaM-13CH) dynamizations and a control treatment without NaM. The variables evaluated were length, aerial and root part fresh and dry weight, leaf area, chlorophyll A, B, total relative water content, and water potential. In general, the plants treated with NaM-13CH showed the highest values for the majority of the morphometric and physiological variables, including the plants subjected to high salinity stress by adding NaCl (200 mM). These results conf irmed that NaM attenuated NaCl stress in chiltepin chili (C. annuum L. var. glabriusculum) plants and that agricultural homeopathy has the potential to increase productivity and yield in  hydroponic cultivation of the species.

Published: March 2020

In the marble industry, a lot of marble is wasted in the form of odd blocks of various sizes and slurry consisting of water and micro-fine particles. The slurry on drying converts into powder. Both slurry and powder have adverse effects on the environment. This research is focused on the gainful utilization of waste marble powder (WMP) by converting it into a valuable binding material. For this purpose, WMP and clay were collected, and their physical and chemical properties were determined. A mix of WMP and clay was prepared and burnt at a temperature around 1300 oC. The burnt mix was ground to powder form to get marble cement (MC). The MC was then used in mortar. The compressive and flexural strengths of mortar cubes and prisms were determined. Apart from this, X-ray diffraction (XRD) analysis, thermo-gravimetric analysis (TGA) and scanning electron microscopic (SEM) analysis were also carried out. The chemical composition showed that the MC has 52.5% di-calcium silicate (C2S) and 3.5% tri-calcium silicate (C3S).The  compressive strength of MC mortar after 28 days curing is 6.03 MPa, which is higher than M1 mortar of building code of Pakistan (5 MPa). The compressive strength of MC mortar after one year is 20.67 MPa, which is only 17% less than OPC mortar.

Published: March 2020

Durability of cement mortar and concrete materials under sea water condition is always an important research topic. The objective of this work is to understand the mechanical properties of corroded cement mortar after high temperature, the cement mortar specimens after high temperature were placed in water and sodium sulfate solution, and then the uniaxial compression tests were carried out on the cement mortar specimens after corroded. Test results show that both the differences of compressive strength and strain at the peak stress after high temperature caused by high temperature, are relatively small when the specimens are eroded in water, and the differences are relatively high when the specimens are eroded in sodium sulfate solution. The compressive strength of the cement mortar specimens under normal temperature eroded in sodium sulfate solution is highest, and that eroded in water is lowest. The compressive strength of specimen after high temperature eroded in water is highest and that eroded in sodium sulfate solution is lowest. The strain at the peak stress of specimen, whether after high temperature or not, is highest when eroded in sodium sulfate solution, and that eroded in water is lowest. At present, there are few research results about the mechanical properties of concrete first after high temperature and then after sea water corrosion. The work in this paper can enrich the results in this area.
R-function Theory for Bending Problem of Shallow Spherical Shells with Polygonal Boundary
Authors: Li Shanqing , Yuan Hong , Yang Xiongfei , Zhang Huanliang , Peng Qifeng
Published: March 2020

The governing differential equations of the bending problem of simply supported shallow spherical shells on Winkler foundation are simplified to an independent equation of radial deflection. The independent equation of radial deflection is decomposed to two Laplace operators by intermediate variable. The R-function theory is applied to describe a shallow spherical shell on Winkler foundation with concave boundary, and then a quasi-Green’s function is established by using the fundamental solution and the normalized boundary equation. The quasi-Green’s function satisfies the homogeneous boundary condition of the problem. The Laplace operators of the problem are reduced to two simultaneous Fredholm integral equations of the second kind by the Green’s formula. The singularity of the kernel of the integral equation is eliminated by choosing a suitable form of the normalized boundary equation. The integral equations are discretized into the homogeneous linear algebraic equations to proceed numerical computing. The singular term in the discrete equation is eliminated by the integral method. Some numerical examples are given to verify the validity of the proposed method in calculating simple boundary conditions and polygonal boundary conditions. A comparison with the ANSYS finite element (FEM) solution shows a good agreement, and it demonstrates the feasibility and efficiency of the present method.

The study investigated the effects of used motor oil on soil physical and chemical variables and their particle size distribution. Two (2) replicate soil samples were collected from  three radial coordinates 50 31.114N 70 02.703E, 50 31.165 N 70 2.670E and 5023.35N 6059.176E  respectively from the auto-mechanic village and agricultural land which serves as control; at depths of 0-15cm and 15-30cm. Standard methods were adopted both for field and laboratory analysis, utilizing  such instruments as Atomic Absorption Spectrometer (model FS 240 Varian), Jewniary, digital pH meter, Refractometer (model E- Line R.ATC- ), lovibond instrument model Cm-21 and mercury-in-built thermometer. Twenty three (23) different soils parameters were analyzed comprising total organic carbon, heavy metals, soil texture and particle size (clay, sand and silt) organic carbon, exchangeable cations (Na, Ca and Mg), conductivity, salinity,  nutrients (N, P, K), bulk density and organic matter. The result indicated a variation at the mechanic site and control point. The pH of the auto-mechanic soils were acidic with the range of 4.3- 5.0 in comparison with the control point which had a mean value of 5.6. Heavy metals had higher values in auto mechanic soils than in the control and their concentration decreased in this trend, Cu 0.940> Hg 0.211> Ni 0.093>  Zn 0.051> Pb 0.021> Cd 0.015 > Ar 0.003; Hg 1.385> Cu 0.853> Ni 0.079> Zn 0.041> Cd 0.04> Pb 0.034> Ar 0.004. This showed that disposal of used motor oil on the soil affected the soil quality negatively. It is therefore; recommended that there should be a legislation to stop the indiscriminate dumping of spent oil and lubricants on the surface of the soil at Orji Mechanic village without treatment prior to disposal.

The experiment was designed according to the Completely Randomized Design (CRD) with three replications and two treatment factors arranged factorially, namely mungbean varieties (varieties of No.129, Merak, Vima-3, Vima-1, and Kenari) and planting patterns (in monocrop and growing together with rice). Data were analyzed with analysis of variance (ANOVA) and Honestly Significant Difference test (Tukey’s HSD) at 5% level of significance using the statistical software CoStat for Windows ver. 6.303. The results showed that there were different responses between several mungbean varieties to growing it together with red rice in relation to growth and yield components of mungbean. The mungbean variety No.129 showed higher seed yields when grown together with red rice (11.78 g/pot), whereas seed yield of the Vima-1 variety was lower (i.e. only 6.5 g/pot) and lowest when grown together with red rice plants compared with growing on the monocrop system (9.32 g/pot), while the Vima-3 variety showed non-significant differences in seed yields between growing together with red rice (11.66 g/pot) and growing in monocrop systems (10.09 g/pot). Therefore field testing experiments are required to find more tolerant mungbean varieties for planting together with rice plants in an intercropping system.

ABSTRAKKegiatan pengabdian masyarakat ini dilakukan karena masih ditemukan beberapa kelemahan dari pengelolaan pondok pesantren. Umumnya masalah tersebut bermula dari aktivitas keuangan pesantren baik yang berkaitan dengan anggaran, akuntansi, penataan administrasi, alokasi serta kebutuhan pengembangan pesantren maupun dalam proses aktivitas keseharian pesantren. Tidak sedikit pesantren yang memiliki sumber daya baik manusia maupun alamnya tidak tertata dengan rapi, dan tidak sedikit pula proses pendidikan pesantren berjalan lambat karena kesalahan dalam penataan manajemen keuangannya. Pelaksanaan Pengabdian Masyarakat ini dilakukan di di pondok pesantren Qotrun Nada Depok Jawa Barat. Peserta diberikan pelatihan pemahaman dan pengetahuan pengelolaan keuangan secara komputerisasi dan pembuatan laporan keuangan yang baik serta kiat-kiat dalam mengelola pengendalian biaya yang rutin dikeluarkan baik yang terjadi pada saat usaha maupun pengeluaran rumah tangga pesantren sehingga mampu mengatasi pengeluaran yang besar. Kesimpulan yang diperoleh terdapat peningkatan pemahaman dan pengetahuan pengelolaan keuangan serta teknik dalam membuat bentuk laporan keuangan yang baik dan benar baik secara manual maupun terkomputerisasi.Kata Kunci: pengetahuan keuangan; laporan keuangan; komputer akuntansiABSTRACT This community development activity was carried out because there were still some weaknesses in the management of pesantren. Generally, the problem starts from the pesantren's financial activities both related to the budget, accounting, administration managements, allocation and development needs of the pesantren and even in the process of pesantren's daily activities. Many pesantren with its resources both human and natural are not neatly arranged, and also the process of pesantren education runs slowly due to errors in financial management arrangements. The implementation of community develompent is done at the Pesantren Qotrun Nada in Depok, West Java. Participants are given training in understanding and knowledge of financial management manually and also accounting computerized application. Participants are also given a training materials of good financial report preparation and tips on managing routine cost control. The conclusions obtained are an increase in understanding and knowledge of financial management for all participants and also understand the techniques in making good financial statements both manually and computerized.Keywords: financial literacy; financial statements; accounting computerized
Gender perspective as a dimension of democracy in schools
Authors: Feu Gelis Jordi , Abril Paco
Published: March 2020

Otherness, the recognition of the non-hegemonic other, is one of the dimensions to work on in the construction of democracy in schools. In this article, we analyse the relationship between sex and gender, and democracy, based on case analysis of five preschool and primary education centres in Catalonia. In each centre, democracy occupies a prominent place in the educational project. The main finding emphasizes that these centres, where democracy is a cornerstone, seldom consider the dimension of gender perspective. Therefore, gender equality policies, increasingly present in the guidelines and legislation of educational administrations, have little impact. However, in one of the centres analyzed, the democratic project is linked to social transformation, which does include gender relations. This is an example of implementation, from the bottom up, based on the reflection and participation of the entire educational community.

El debate sobre los deberes escolares se centra en la mayoría de los casos en la conveniencia de su uso, tanto por parte de las instituciones educativas como por parte del profesorado.  El objetivo es explorar el conjunto de factores que influyen en el profesorado de Educación Primaria a la hora de enviar deberes, con el fin de identificarlos y clasificarlos. Este trabajo se encuadra dentro de un estudio sobre los factores que influyen en la decisión de los docentes de educación primaria para enviar deberes escolares a sus alumnos, a través de un análisis de factorial. Participan 609 docentes de España y Ecuador que imparten docencia en Educación Primaria. Para el desarrollo de esta investigación hemos diseñado el Cuestionario sobre los factores que influyen en el profesorado de Educación Primaria al asignar deberes escolares a su alumnado. La evaluación de la consistencia interna de las preguntas del cuestionario se realizó utilizando el estadístico alfa de Cronbach. Se ha investigado la estructura factorial utilizando un procedimiento de validación cruzada. Los resultados evidencian que posee unas características psicométricas muy aceptables, buena consistencia interna y fiabilidad. Asimismo, los datos muestran la existencia de cuatro factores principales que determinan la decisión del docente como son la presión social, las creencias, el ambiente de trabajo y los sentimientos.

Published: March 2020

El estudio realizado tiene como objetivo averiguar si la aplicación de metodologías didácticas activas en la etapa de educación primaria tiene consecuencias en el rendimiento académico de este alumnado en los inicios de la etapa de la educación secundaria obligatoria. Para ello se ha planteado una investigación de carácter cuantitativo, con un diseño cuasi experimental, donde se comparan en primero de la ESO los resultados del alumnado, que ha cursado educación primaria en dos centros públicos de una misma zona geográfica de la isla de Mallorca, con lo que se controlan las variables extrañas: en el primer centro se aplican desde siempre metodologías activas, mientras que en el otro se siguen metodologías tradicionales. La totalidad del alumnado de ambos centros se escolariza en secundaria en el mismo instituto, único de la zona. Los resultados obtenidos, a partir del estudio de los últimos seis años de cada centro para tener una secuencia y evitar características individuales de cursos concretos, nos muestran que no existen diferencias estadísticamente significativas en los resultados académicos por centro de procedencia. Estos resultados ponen de manifiesto que la utilización de metodologías activas en educación primaria no supone ninguna desventaja en cuanto al rendimiento académico cuando este alumnado cursa primero de la ESO en una metodología tradicional.

Authors: Ibrahim Ahmed Sattar , Al-bidry Mayssaa Ali
Published: March 2020

The aim of this study is to identify the effect of particle size and to increase the concentration of Iraqi bentonite on rheological properties in order to evaluate its performance and to know if it can be used as drilling fluid without additives or not. In this study, Iraqi bentonite was carried out by mineral composition (XRD), chemical composition (XRF) and Particle size distribution (PSD), and its rheological properties were measured at different particle size and concentration. The results showed that when the particle size of Iraqi bentonite decreased, and the rheological properties were increased with increased concentration of Iraqi bentonite. Also, Iraqi bentonite was unable to use as drilling fluid without certain additives.

Stephanosphaera pluvialis Cohn is considered a rare alga, a habitant of rock pools. There are no signs of its findings after the mid 1930s in Russia, and it has never been seen in the Russian White Sea islands or in the Leningrad Region of Russia. In mid July, 2007, however, it dominated in two small pools in the Kandalaksha Bay of the White Sea (66°19′40ʺ N, 33°52′10ʺ E) and in early September, 2013 in two very small puddles on the western coast of Lake Ladoga (60°34′15ʺ N, 30°41′9ʺ E). The cenobia and cells from both Ladoga probes were studied under the light microscope during long-time cultivation in a mixed culture, using liquid mineral medium supplemented by vitamins B6 and B12. In fresh material, the greater part of revealed 8- and 4-celled coenobia and cells were larger than it was described by Cohn, namely the sizes of coenobia in the first puddle were 62–66 μm, those of the cells 22–28 μm; the coenobia in the second one were 70–85.5 μm, the cells 26–30 μm. After 1.5–2 months cultivation, there were observed single coenobia of spherical cells organized in tetrades or giant (100 μm) coenobia with dying cells. In that period and later, single cells with thickened walls (cysts or zygotes) of different sizes were revealed. After 5 months of cultivation, few single cells with short appendix or very small young coenobia with rounded cells were observed.
