Characterization and Control of Pestalotiopsis spp. the Causal Fungus of Guava Scabby Canker in El-Beheira Governorate, Egypt
Authors: El-argawy Eman
Published: May 2020

During 2013-2014 growing seasons, forty three isolates of Pestalotiopsis spp. were recovered from guava leaves and fruits showed scab symptoms from different regions in EL-Beheira governorate. Five Pestalotiopsis species were recognized according to the morphological characteristics of fungal colony (Colony color, Size and number of acervulii) and conidia (length, width, and color of median cells, length and the number of apical and basal appendages); they were P. psidii, P. microspora, P. clavispora, P. neglecta and Pestalotiosis spp. All the isolates recovered were pathogenic to the cv. Balady of guava fruits. However, P.psidii isolates were the most highly pathogenic followed by P. neglecta, P. clavispora, P. microspora and Pestalotiopsis spp, respectively. RAPD-PCR analysis using five random oligonucleotide primers revealed DNA fingerprints and considerable variations were revealed with primers tested.  Bar primer showed a common band for all Pestalotiopsis isolates and species at 500bp, while BAQ, 18 and A9B4 exhibited banding pattern similar for all isolates of the same species which were different from that of the other species. Scab disease control of infected fruits by chitosan as a natural product was tested. The in vitro 2.5% chitosan application significantly inhibited the growth of Pestalotiopsis spp. tested by 86.53% on agar plates. The in vivo tests on fruits, the chitosan treatment to artificially infected fruits reduced the development of symptoms at the different chitosan concentrations, i.e., 1.5%, 2% and 2.5%. The 2.5% chitosan was the most effective concentration for scab disease control in guava fruits. It is the first report of identification five different Pestalotiopsis  species affecting guava fruits and leaves in EL-Beheira Governorate, Egypt. Also, the study supported the view that chitosan offers a safe alternative to synthetic fungicides in postharvest scabby control and could be considered as a potential agrochemical of low environment impact.

Published: May 2020

The effect of osmotic and matric potentials on mycelial growth, sclerotia production, germination, and virulence of two isolates of Sclerotinia sclerotiorum, and one isolate of S. minor were studied on potato dextrose agar (PDA) media adjusted with KCl, glycerol, or agar. Osmotic potentials created by KCl and glycerol significantly reduced vegetative growth of the three isolates. On matrically adjusted PDA, vegetative growth of the three isolates was not negatively affected by matric stress up to -3.5 MPa. When KCl was the osmoticum, sclerotia number did not follow a consistent pattern. However, sclerotia number decreased when osmotic stress created by glycerol was increased. Matric stress was not a consistent factor affecting sclerotia production by both species.  However, the highest levels of matric stress -3.0 and -3.5 MPa significantly reduced sclerotia production by both species. In general, there was a trend toward lower sclerotial germination with increasing osmotic and matric stress. Pathogenicity of S. minor and S. sclerotiorum on the peanut cultivar (Okrun) was reduced by high concentrations of KCl. Mycelia of both species produced at high matric potential -3.5 MPa did not differ in pathogenicity on Okrun compared with mycelia grown on non-amended PDA. In water-stressed-Okrun, induced by polyethylene glycol 8000, the Area under Disease Progress Curve (AUDPC) was significantly decreased. The relevance of these results to the behavior of S. minor and S. sclerotiorum, and their pathogenicity on peanut is discussed.

Published: May 2020

Alternaria core rot and Alternaria black heart rot of apple and pomegranate fruit, respectively, are major pre- and postharvest diseases worldwide. However, it is very difficult to differentiate the rot related Alternaria species in the Alternaria complex as they are not always correlate to species-groups based upon morphological characteristics and due to the limited genetic variation these species exhibit among each other. Therefore, it is crucial to exploit novel assays towards the accurate identification and differentiation of these Alternaria species. We have developed, a real-time PCR assay [using species specific primers targeting the endopolygalacturonase (EndoPG) gene] combined with a high-resolution melting (HRM) curve analysis for discrimination of the 14 single nucleotide polymorphisms (SNPs)-based Alternaria haplotypes, which were assigned based on the aligned sequence profiles of 138 Alternaria spp. strains previously isolated from apple and pomegranate rotted fruit. This analysis specifically generated 14 unique HRM curve haplotype profiles among the Alternaria complex species tested. The results showed that HRM curve analysis allows the rapid and adequate identification and genotyping of the three Alternaria species (A. alternata, A. tenuissima and A. arborescens) responsible mostly for the apple and pomegranate fruit rot diseases.

An investigation was carried out to test for the pathogenicity of fungi associated with the deterioration of two varieties of cocoyam corms and cormels. Fifty (50) infected corms and cormels with symptoms of post-harvest rots were purchased from six markets within Plateau Central zone and analyzed. Eleven (11) fungal isolates were implicated in the deterioration of the two varieties of the cocoyam (C. esculenta var. antiquorum and C. esculenta var. esculenta) corms and cormels and were identified as; Alternaria alternata, Fusarium oxysporum, Verticilium lateritium, Botryodiplodia theobramae, Colletotrichum coccoides, Phythium myriotylum, Fusarium verticillioides, Rhizopus stolonifer and Geotricum candidum. The result showed that all these fungi were highly virulent on the two varieties, except C. coccoides, F. verticillioides and A. alternata which did not caused rot on C. esculenta var. esculenta. Meanwhile, the fungus Rhizopus stolonifer induced the highest percentage mean area of rot (39.96%) followed by Alternaria alternata (39.36%), Phythium myriotylum (38.60%), Botryodiplodia theobromae (36.89%) while the least was Fusarium oxysporium (27.66%) in C. esculenta var. antiquorum. The study further revealed the highest rot induced on C. esculenta var. esculenta by the isolated fungi, V. lateritium (42.45%) followed by G. candidum (34.29%), F. oxysporum (27.96%) while the least was Rhizopus stolonifer (20.33%). The result also showed that C. esculenta var. esculenta was comparatively more susceptible or significant (P<0.05) to the fungus V. lateritium since it showed a greater (extensive) mean percentage area of rots of 42.45% on the corms and cormels than on C. esculenta var. antiquorum with 36.01%.

Published: May 2020

The ability of trees forming arbuscular mycorrhizal (AM) associations to get established in ectomycorrhizal forests is still unknown (Weber et al., 2005). The success of both establishment and adaptation depends on the type of interactions between the plants introduced and the type of indigenous soil microbiota (Fahey et al., 2012). Thuja plicata is an AM forest tree successfully established (since 1962) in an artificial trial plantation in the region of Chalkidiki (northern Greece). The successful adaptation of an AM tree in an ectomycorrhizal forest raises questions about the feasibility, if any of the mycorrhizal association under these conditions, as well as on the kind of this association and the species of mycorrhizal fungi putatively involved. During a survey, roots fragments were excised from three Thuja plicata trees and were co-cultured with leek roots (Allium porrum, var. bleu de solaise) in the greenhouse. The successful colonization of the leeks by AM fungi was confirmed by the presence of arbuscular and vesicular structures in the roots after microscopic examination. Colonized Allium porrum roots have then been harvested, surface disinfected (90% ethanol for 10 seconds, 6% sodium hypochlorite for 5 min) and plated on agar solidified medium in Petri dishes. Molecular identification of the mycorrhizal fungal species involved in this symbiosis, was performed after total nucleic acids were extracted using the DNeasy Plant Mini Kit (Qiagen, Crawley, UK). A portion of the 18S ribosomal RNA region was amplified using the primers AML1 (5’ AACTTTCGATGGTAGGATAGA 3’), AML2 (5’ CCAAACACTTTGGTTTCC 3’). The PCR amplicon was cloned using TOPO TA Cloning Kit (Invitrogen, Paisley, U.K.) and sequenced (GenBank accession Nos. KU365383 - KU365385). All partial sequences revealed 99% nucleotide homology with the 18S rRNA sequence of a Funneliformis mosseae fungus isolate (KP144312). To our knowledge, this is the first record of Thuja plicata associated with Glomeromycetes AM fungal communities in an ectomycorrhizal forest in Greece
Combination of Different Antagonistic Bacteria to Control of Potato Blackleg Disease Caused by Pectobacterium atrosepticum under Greenhouse and Field Conditions
Authors: El-Hendawy Hoda H. , Abo-Elyousr Kamal A. M.
Published: May 2020

Three different antagonistic bacterial isolates, Pseudomonas fluoresces (Pf2), Bacillus subtilis(Bs3) and Rahnella acquatilis (Ra39) restricted the growth of Pectobacterium atrosepticum, the causal agent of black leg disease of potato, in vitro.   Under greenhouse and field conditions, potato plants pre-treated with the three antagonistic bacterial isolates, individually or in combination, showed reduced disease severity relative to non-treated control plants. All isolates produced siderophores in different degrees but did not produce indole acetic acid (IAA) or hydrogen cyanide (HCN).The obtained results indicated that combination of Pseudomonas fluoresces (Pf2), Bacillus subtilis (Bs3) and Rahnella acquatilis (Ra39) is beneficial in controlling black leg disease of potato caused by pectobacterium atrosepticum.

Published: May 2020

Soft rot of Zantedeschia, caused by Pectobacterium carotovorum subsp. carotovorum (Pcc), has caused a significant worldwide threat to calla lily production. Hence, in order to effectively manage the disease, an intensive management programme aimed at adequte suppression of the pathogen is paramount. In order to investigate the antibacterial effect of a Coptis chinensis extract product against the soft rot- causing bacterium, an in vitro study was set up. Bacterial isolate were obtained from rotting calla lily tubers and maintained in Nutrient Broth under refrigeration. Sterile petri plates containing 15 ml of Nutrient agar were prepared and aseptically inoculated with 0.1 ml an overnight grown culture of a standardized Pectobacterium carotovorum subsp. carotovorum inoculum containing about 1x 108 cfu/ml. The inoculum was spread evenly over the whole surface of the plates. After solidification, 1 ml of the different concentrations of C. chinensis (1, 10, 25, 50 and 100%) were placed individually at the centre of the inoculated petri plates. Positive check was maintained using Streptomycin sulphate (100ppm) and a negative check using sterile distilled water. Eight replicates were maintained for each treatment and the experiment was repeated twice. Results indicated that the lower concentrations of C. chinensis did not cause any inhibition against Pcc. On the other hand, 100% C. chinensis made an inhibition zone comparable to that streptomycin sulphate. Our results demonstrated that C. chinensis has antibacterial activity and therefore feasible for use in crop protection against soft rots caused by Pectobacterium carotovorum subsp. carotovorum.

Authors: Olabiyi Timothy I. , Ojo Oladiran J.
Published: May 2020

Efficacy of neem leaf based compost andTrichoderma harzianum solution were assessed on root knot nematode pest of two cowpea varieties at the screen house of the International Institute of Tropical Agriculture (IITA), Ibadan during 2012 planting season. The two cowpea varieties which have been confirmed to be susceptible to root knot nematode, IT96D-610 and IT84S-2246-4 were the test crops. The experimental pots (10kg soil) were inoculated with 5,000 root knot nematode eggs. The treatments were neem compost and T. harzianum solution with application rates of 2 ton/ha and 1x10-7 spores respectively. The pots that were not treated served as the control. Each treatment was replicated 4 times while the statistical design was complete randomized design. Data were collected on the growth and yield of cowpea, and also on the nematode populations in the soil and cowpea root. The results indicated that neem compost and T. harzianum solution significantly increased the growth and yield of IT96D-610 and IT84S-2246-4 cowpea varieties grown in the root knot nematode inoculated soil. The populations of root knot nematode in the soil and cowpea root were significantly reduced. The level of root damage (root gall) was significantly reduced in the neem compost and T. harzianum treated cowpea when compared with the untreated control.
Effect of Crop Rotation on Tomato Bacterial Wilt (Ralstonia solanacearum) and Survival of the Pathogen in the Rhizospheres and Roots of Different Crops in Ethiopia
Authors: Ayana Getachew , Fininsa Chemeda
Published: May 2020

Survival of Ralstonia solanacearum in a environment or ecosystem depends on many factors, such as the race or strain of the pathogen, physical, chemical, biological soil factors and presence or absence of a host and non-hosts plants. The objectives of this study were to assess the effect of one and two season rotation sequences on the development of tomato bacterial wilt; and the survival ability of R. solanacearum in the rhizosphere and roots of presumable hosts and non-host crops in Ethiopia. A one season crop rotation involving tomato- maize-tomato, tomato- common beans -tomato and two season rotations consisting of tomato - maize- common bean-tomato, tomato –common beans – maize-tomato and tomato – tomato- tomato were established at Melkassa in Ethiopia. The effect of the system was evaluated on bacterial wilt of tomato under field conditions using a susceptible tomato cultivar (Marglobe). In one season rotation treatment involving common bean and maize after tomato resulted in a reduction of an average 6% and 16% final wilt incidence, respectively. Similarly, in the two seasons rotation sequence growing tomato after bean-maize and maize-bean resulted in about 29% average final wilt incidence reduction. The onset of wilt incidence was also delayed by one week in the two season rotations with common bean and maize compared to continues tomato growing and one season rotation with non-host crops. Survival of ability of R. solanacearum, strain designated as TomNa3 biovar 1 race 1 was studied under soil rhizosphere and roots of presumably non-host and hosts of different crops under glasshouse conditions. The pathogen was detected in rhizosphere soils and roots of presumable non-host and hosts for the pathogen after 120 days after inoculation. The population of bacterial pathogens was recorded in a declining trend but detectable in the rhizosphere soils and roots of presumable non-host crops at 30, 45, 60, 90 and 120 days after inoculation.
The Role of Salicylic Acid and Pseudomonas fluorescens in Systemic Resistance Against Rhizoctonia solani kühn in Guar (Cyamopsis tetragonoloba (l.) Taub.)
Authors: Abdel-Monaim Montaser F.
Published: May 2020

Rhizoctonia solani was found to be associated with root rot symptoms of guar plants collected from different fields in New Valley governorate, Egypt. All the obtained isolates were able to attack guar plants (cv. Local) causing damping-off and root rot diseases. R. solani isolates No. 8 (RG8) was the more virulent ones in the pathogenicity tests. Salicylic acid (SA) and Pseudomonas fluorescens (PF) individually or in combination were examined for their potential in suppression damping-off and root rot and growth promotion of guar plants in vitro and in vivo. Both SA and P. fluorescens either individually or in combination inhibited the growth of the tested pathogenic fungi.SA combined with P. fluorescens recorded the highest inhibited growth followed by P. fluorescens alone. Under greenhouse and field conditions, all treatments significantly reduced damping-off and root rot severity. The combination of SA and P. fluorescens was more effective than using them individually.  Under field conditions, all these treatments significantly increased growth parameters (plant height and No. of branches plant-1) and yield components (No. of pods plant-1, weight of 100 seeds and total yield fed.-1 and Guaran content (gm plant-1) in both locations (El-Kharga and Mallawy Agric. Res. Stations) during growing season 2014.The combination of SA and P. fluorescens were recorded the highest growth parameters and yield components. Generally, the combination of SA and P. fluorescens recorded the best results for controlling damping-off and root rot diseases in greenhouse and field with addition improved plant growth and increased yield components in the field. In physiological studies, activity of defense-related enzymes, including peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL), pathogenesis related (PR) protein (chitinase and β 1,3 gluconase), were increased in inoculated and non-inoculated plants treated with the SA and P. fluorescens either individually or in combination, during the experimental period. The combination of SA and P. fluorescens recorded the highest increase in activity of all enzymes.  In general, the activity of these enzymes begins to accumulate after two days of treatment and reached maximum levels at 6 to 10 days, then the activities of these enzymes were decreased progressively. On the other hand, total phenols and lignin increased in guar plants inoculated with R. solani and treated with SA and P. fluorescens individually or in combination. The highest accumulation of phenols was recorded 8th days from application, while lignin recorded the highest level at 10th days from application. In the end, these results suggested that SA and P. fluorescens either individually or in combination may play an important role in controlling the guar damping-off and root rot diseases, though they have induction of systemic resistance in guar plants.

The study deal with potentiality of some bioagents for controlling the root rot of black cumin under greenhouse conditions, caused by Fusarium spp. Eight fungal isolates were obtained from diseased of back cumin plants collected from Assiut Governorate. These isolates were belonged to the genus Fusarium spp. They were identified as, four isolates of F. comptoceras, three isolates of F. solani and one isolate Fusarium lateritium. Pathogenicity tests indicated that all tested fungal isolates were able to infect black cumin plants causing symptoms of root rot resulted in dwarfism and death before the capsules mature. They varied in their pathogenicity, Fusarium comptoceras No.1 gave the highest percentage of disease severity and percentage of infection on black cumin plants (53 and 50% respectively), while isolates F. comptoceras Nos. 3 and F. solani No. 6 gave the lowest percentage of infection (15 and 17% respectively) the rest of isolates showed moderate of percentage of infection. Antagonistic capability of 15 isolates (PGPR) was tested in vitro against growth of three isolates of Fusarium spp. the causal pathogen of root rot of black cumin. Seeds black cumin plant treated with all bioagents as a suspension significantly increased the root dry weigh and foliar dry weigh compared to infected control. In conclusion, our study confirmed that used of bioagents may be applied as future ecofriendly alternatives to synthetic fungicides for controlling the disease of black cumin.

Authors: Rachman Aditya , Aspin Aspin , Belinda Siti
Published: May 2020

The unbalance on the supply and demand on the energy has an impact on the escalating energy price and potentially impedes the development. One of the power demands comes from the energy utilization in the building sector, in which the cooling system is among them. The application of the air conditioning based on the refrigerator system is obviously consuming much energy in the building. Thus reducing the role of this power consumed cooling system is so imperative. To apply the circulating fan or to employ the natural ventilation are among the alternative approaches to make a building cooler, without much consuming energy. The aim of this study is to investigate the effect the circulating fan and the natural ventilation, on the temperature and the humidity in a building in Southeast Sulawesi, a region with its high daily solar radiation. It conducts an experiment on a building model incorporated with the ventilation and the circulating fan. The result shows that by incorporating these alternative cooling devices, the temperatures in the building can be lower than that of a closed building (no fan and no ventilation). The magnitude in the decreasing on the temperature for the building with circulating fan is higher than that of the ventilation. Another result on the investigation shows that the relative humidity in the building with the circulating fan or the ventilation is relatively higher than that of the closed building.

Esta pesquisa objetivou refletir sobre, históricas e atuais interações socioambientais. Para tanto, utilizou-se de revisões teóricas enfatizando, “o princípio responsabilidade”, promovido pelo teórico Hans Jonas, importante filosofo que viveu durante o período da Segunda Guerra Mundial e do Holocausto Judeu; tais acontecimentos motivaram suas pesquisas e influenciaram decisivamente na construção do “princípio responsabilidade”, o qual estabelece importantes interações com os conceitos de sustentabilidade e desenvolvimento sustentável. No estudo, apresenta-se um panorama dos problemas ambientais, onde se percebeu dicotomia nas históricas e atuais formas de atuação da humanidade para com a natureza, o que motiva novas compreensões acerca do compromisso ético do homem para com o meio ambiente. Para tanto, a revisão sobre “o princípio responsabilidade” do filósofo Hans Jonas, motivou importantes considerações estabelecidas nessa pesquisa. Sendo assim, ressalta-se a relevância do tema, frente às atuais configurações do mundo contemporâneo.  Portanto, a responsabilidade ambiental deve ser refletida nos diferentes setores socioculturais, de forma a ser valorizada e colocada em prática, buscando fomentar técnicas educativas capazes de legitimar novas interações, haja vista o avanço nas pesquisas e a progressão no conhecimento nesse campo, frente às atuais demandas socioambientais.

Os parques são atrações voltadas para entretenimento e lazer da população local e turística. Os parques aquáticos estão vinculados à atividades com predominância de recursos hídricos. Essas atividades proporcionam um bem-estar social ao indivíduo, mas, a crescente implementação desses parques, vêm ocasionando problemas ambientais, como contaminação dos mananciais e ocupação humana em áreas protegidas. Compreender a percepção da população local é importante para identificar os principais problemas enfrentados no dia a dia, e quais impactos positivos e negativos que ocorrem dentro da comunidade. O objetivo desta pesquisa foi analisar a percepção dos impactos negativos e positivos da comunidade do Sítio Farias. Para o levantamento de dados, foram entrevistados 50 moradores que vivem no Sítio Farias. A análise dos impactos foi quantificada a partir de uma escala do grau de impacto. A partir da analise foi observado que os pontos com maior intensidades foram os negativos, onde estão relacionados com os aspectos ambientais, principalmente em relação ao abastecimento de água e doenças vinculadas a insetos. Outro impacto negativo citado pelos entrevistados foi à seca das “levadas” e a geração de mau cheiro próximo ao riacho do Farias. Os impactos positivos que tiveram maior relevância foram os aspectos econômicos (melhoria da economia do distrito) e de desenvolvimento social (coleta de lixo três vezes na semana).O estudo evidenciou a falta de dialogo entre a gestão do Parque e os moradores.

Published: May 2020

The paper briefly presents some essential concepts and features of light fields with strong spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a characterization of optical vortices, speckle fields, polarization singularities. A special attention is paid to the field dynamical characteristics (energy, momentum, angular momentum, and their derivatives), which are considered not only as mechanical attributes of the field but also as its meaningful and application-oriented descriptive parameters. Peculiar features of the light dynamical characteristics in inhomogeneous and dispersive media are discussed. The dynamical properties of paraxial beams and evanescent waves (including surface plasmon–polaritons) are analyzed in more detail; in particular, a general treatment of the extraordinary spin and momentum, orthogonal to the main propagation direction, is outlined. Applications of structured light fields for optical manipulation, metrology, probing, and data processing are described.

Published: May 2020

Diabetes mellitus is a common metabolic disease. Nowadays, sleep complaints are increasing day by day due to the restriction in bed time resulting in chronic partial sleep loss.(1)Type 2 diabetes mellitus accounts for 95% of all of diagnosed diabetes worldwide. Several studies have recognized sleep disorder as a novel risk factor for diabetes.(2)Sleep disorder plays a vital role in the development of diabetes via various metabolic and neuroendocrine pathways.(3) Nocturia and neuropathic pain were explained as two possible causes of decreased sleep quality.(1) People who have sleep disorder either in the quality or quantity experienced reduced insulin sensitivity, which results in elevated blood glucose that can aggravate the progress of diabetes. There are limited studies from India on the association of sleep quality and diabetes control status. In this study, we aimed to find the quality of sleep in patients with type 2 diabetes mellitus and its correlation with glycaemic control.

Considering the nutritional values of Mentha viridis. L and Aloe veraplants, these plants can be utilized for the production of alternative cultivation media. The cost of artificial culture media is very high, and some components may be unavailable. Use of the plant-based culture media would drastically reduce the expense of the synthetic media. Fifteen bacterial isolates were isolated from Aloe vera rhizosphere, nine bacterial and nine actinomycetes isolates were isolated from Mentha viridis rhizosphere both cultivated in Sirs EL- Layan, El-Menoufia governorate, Egypt. In-vitroscreening was done for the production of indole acetic acid (IAA) and phosphorus solubilization. Results revealed that bacterial isolate No. MB4 produced a high amount of IAA(36.51 μg/ml) on the Mentha-based culture medium, No. A6 showed maximum IAA production (16.25μg/ml) on the Aloe vera-based culture medium and isolate No. MA6 was efficient in phosphorus solubilization (867.85μg/ml) that was isolated from the Mentha viridis. L rhizosphere.16s rRNA analysis of these isolates revealed they are (Pseudomonas monteilii strain CIP 104883, Streptomyces rochei strain DW3 and Kosakonia radicincitans strain DSM 16656 respectively.
Екологічне виховання як творчий процес у соціальній роботі
Authors: Anatska Natalia , Svidlo Tatyana
Published: May 2020

У статті розкрито питання творчого підходу до екологічного виховання як однієї зі змістовних характеристик соціальної роботи. Актуальність теми дослідження зумовлена потребою у соціальній роботі творити нові цінності, які є засобом самовираження людини, та створювати запити соціально-екологічної практики саме через розуміння єдності людини та природи. У цьому контексті екологічне виховання формує життєво-ціннісні орієнтації особистості, що є досить важливим аспектом соціальної роботи. Показано, що соціальна робота в Україні здійснюється в умовах екологічної, економічної, соціальної кризи, а отже, актуальність її постійно зростає, тому що здійснює допомогу і підтримку людей, які потрапили у складні життєві ситуації, та спрямовує їх на самостійне розв’язання цих питань. Таким чином, екологічне виховання передбачає високий рівень знань, який сприяє формуванню екологічної свідомості, тобто усвідомленню екологічної цілісності природи. Це означає, що екологічні знання мають вагу, коли як результат виховання стають екологічними переконаннями, на що і спрямована соціальна робота. Водночас, соціальна робота має головним завданням долучити природний світ до життєво-ціннісних орієнтацій сучасної людини, оскільки він є важливим компонентом структури особистості, котрий визначає ставлення людини до навколишнього світу, її діяльність і поведінку. Потрібно навчити спеціаліста мати бажання знаходити засоби оновлення природи й показувати це в кожній конкретній дисципліні.
Повышение энергоэффективности систем ультрафиолетового обеззараживания воды
Authors: Bogun P. , Kniazeva E.
Published: May 2020

Проанализирована производительность ряда представленных на рынке систем ультрафиолетового обеззараживания воды в сравнении с системами с максимальной производительностью, полученной в результате теоретических исследований, при одинаковом энергопотреблении. Показано, что максимальные значения производительности, заявленные производителями систем, в 1,12 раза меньше, чем можно было бы получить для тех же конструкций при обеспечении однородности облучения обрабатываемого потока. Предложено техническое решение, позволяющее обеспечить однородность облучения за счет формирования распределения скорости потока, убывающего с расстоянием от лампы пропорционально убыванию средней по длине лампы интенсивности облучения. Такое решение позволяет существенно приблизиться к максимальной расчетной производительности при незначительных изменениях в конструкции и минимальных затратах. Исследовано распределение потоков обрабатываемой воды в системе с диафрагмами-рассекателями, формирующими необходимое направление потока. Показано, что для корпуса-реактора длиной до 50 см можно ограничиться одной диафрагмой, а для корпусов большей длины вопрос решается установкой дополнительных рассекателей. Показана возможность применения предложенного решения для любых систем с продольным потоком относительно расположения УФ-ламп.

The performance of a number of ultraviolet water disinfection systems available on the market is analyzed in comparison with systems of the maximum capacity reached as a result of theoretical studies, at the same energy consumption. It is demonstrated that the maximum performance values declared by the system manufacturers are 1.12 times less than could be obtained for the same designs, provided the irradiation uniformity of the treated flow is ensured. A technical solution is proposed that provides for the uniform exposure due to the flow velocity distribution that decreases with the distance from the lamp in proportion to a decrease in the average irradiation intensity along the length of the lamp. This solution allows approaching significantly the maximum design performance with the minimal cost and minor changes in the design. The distribution of treated water flows in a system with diaphragms-spreaders that ensure the required flow direction, is investigated. It is demonstrated that for a reactor vessel up to 50 cm long one diaphragm is enough, whereas for larger vessels installing additional flow spreaders can solve the problem. Possible use of the proposed solution for any systems with a longitudinal flow relative to the location of the UV lamps is shown.

Рассмотрена проблема очистки нефтесодержащих вод энергетических предприятий. Большое внимание уделено очистке технологического конденсата, характеризующегося повышенной температурой (5570 С). Рассмотрена пневматическая флотационная установка, используемая для очистки технологического конденсата на Южной ТЭЦ ОАО Ленэнерго . Приведены основные недостатки установки: изменение свойств резины, из-за чего изменяются размеры пузырьков воздуха и снижается эффективность. Решением проблемы может стать использование эжекционной системы аэрации с диспергатором. На лабораторной установке проведены эксперименты по определению дисперсного состава пузырьков, генерируемых эжекционной системой аэрации при температуре 55 С. Также проведена очистка модельной нефтесодержащей сточной воды в установке с пневматической и эжекционной системами аэрации. Средний размер мелкодисперсных пузырьков, генерируемых эжекционной системой аэрации с диспергатором, составил 60мкм, крупнодисперсных пузырьков 105мкм. Показано, что использование эжекционной системы аэрации с диспергатором позволяет снизить остаточную концентрацию нефтепродуктов с 4 до 1мг/л либо сократить время очистки с 25 до 15минут.

The problem of processing oily wastewater generated at power plants is discussed. Much attention is paid to the purification of process concentrate that is characterized by higher temperature (5570 С). A pneumatic flotation unit used for the process concentrate treatment at the South CHP plant operated by Lenenergo OJSC is considered. The major drawback of the unit is pointed out: the changes in the rubber properties result in the changes in air bubble dimensions, and the efficiency decreases. A possible solution to the problem can be the use of an ejection aeration system with a disperser. The experiments in a laboratory unit on determining the size distribution of the bubbles generated by the ejection aeration system at 55 С were conducted. In addition, model oily wastewater was subject to purification in a unit with the pneumatic and ejection aeration systems. The average size of the finely dispersed bubbles generated by the ejection aeration system with a disperser was 60 m, and that of the coarse bubbles was 105 m. It is shown that the use of the ejection aeration system with a disperser provides for reducing the residual concentration of oil products from 4 to 1 mg/l or reducing the purification time from 25 to 15 minutes.

Üveghulladék előkészítési technológia a körkörös gazdaság jegyében
Authors: Voith Katalin
Published: May 2020

A háztartásokban keletkezett csomagolási üveghulladék 100 %-ban újrahasznosítható. Ez fontos tény, mivel az Európai Unió 2018/852/EU csomagolási irányelve alapján minden tagországnak törekednie kell arra, hogy megelőzzék a csomagolási hulladék gyártását. Ezen túlmenően a hangsúlyt a csomagolási hulladék újrafelhasználására, újrafeldolgozására kell helyezni. Megakadályozva ezzel a csomagolási hulladék végleges ártalmatlanítását, azaz megtörténik a körkörös gazdaságra való áttérés. A körkörös gazdaság olyan gazdaság, amely minimalizálja az erőforrások, hulladékok, kibocsátások és az energia elszivárgását. Ez tartós tervezés, karbantartás, javítás, újrafelhasználás és újrahasznosítás révén érhető el. Az EU 2018/852/EU irányelvének célkitűzése, hogy 2025. december 31-ig az üveg csomagolási hulladéknak 70 %-át dolgozzák fel újra. Ez a szám 2030-ra 75 %-ra kell megemelkedjen. A témaválasztás fő oka ez az EU-s célkitűzés. A cikk az üveg csomagolási hulladék környezetszempontú előkészítési folyamatának technológiatervezését tekinti át.
Una respuesta a la orfandad del hombre contemporáneo
Authors: Maillard García María Luisa
Published: May 2020

A finales de los años ochenta, María Zambrano, después de haber reflexionado ampliamente sobre la crisis de Occidente, califica la situación del hombre contemporáneo de orfandad. La crisis tiene un elemento positivo, el de propiciar algo nuevo, la orfandad es un callejón sin salida. En este artículo pretendemos demostrar que la acogida en España y fuera de nuestras fronteras del pensamiento de Zambrano puede ser debida a que habla directamente al corazón y al alma del hombre contemporáneo, realidades profundas que han sido desechadas por el pensamiento triunfante en Occidente, por un error en el enfoque de nuestra interioridad. Para ello, recurrirá a un lenguaje simbólico, en la convicción de que el símbolo reconoce a la vida humana su carácter poético y que el pensamiento es mucho más que el uso del concepto, del juicio, del razonar y aún de la intuición.
Notas para una crisis
Authors: Carrillo Espinosa María
Published: May 2020

Este artículo está dedicado un ensayo temprano de la pensadora andaluza María Zambrano titulado La vida en crisis (1942). El objetivo central de este análisis es explorar las pistas que ofrece la autora sobre definición de una crisis y la posible salida de esta. Para esbozar un panorama más completo de su pensamiento se establecerán relaciones con otros textos de la misma época incluidos en su libro Hacia un saber sobre el alma (1950), de la misma forma en que se verá su continuidad en textos de madurez como El hombre y lo divino (1955), La tumba de Antígona (1967) y Los bienaventurados (1990). En conjunto, estos textos abren la hipótesis de si para la escritora andaluza el camino de salida de una crisis es una consecuencia de la recuperación de lo que ella llama «saber sobre el alma»; esto es, si solo después de construir un espacio reflexivo interior, en los términos que precisa la autora, es posible pasar de forma serena por un momento de crisis.
