Purpose: to reveal the effect of different doses of mineral fertilizers (MF) on the growth, development and productivity of soybeans on meadow-chernozem soils of Rostov region. Materials and methods. The studies were carried out on meadow-chernozem soils of Oktyabrsky district Rostov region in 2019–2020. Observations of the effect of different doses of MF on the growth, development of plants, yield records, statistical processing of the results were carried out according to generally accepted methods of conducting field experiments. Results. It was found that, on average for 2 years, the greatest plant growth was observed in the variant with the calculated MF dose for the planned yield of 5.0 t/ha. The height of plants in this variant in the branching phase averaged 24.8 cm for 2 years, in the flowering phase – 54.7 cm, and in the phase of bean filling – 117.6 cm. This is, respectively, 23, 21 and 13 % higher than the control. The largest increases in leaf surface area in this variant were revealed: on average for 2 years, they amounted to 13% in the phases of branching and filling of beans and 18 % in the flowering phase. At the same time, in the variant with the MF dose for the yield of 4.0 t/ha, the increments to the control were respectively equal to 9, 16, 13 %, and in the variant with the MF for the yield of 3.5 t/ha – 6, 12, 8 %, respectively. Similar changes were revealed in the accumulation of dry aboveground biomass. Conclusions. The greatest impact on the height of soybean plants was exerted by the application of MF with a dose calculated for the planned yield of 5.0 t/ha. On average, for 2 years, the height of plants in this variant was 117.6 cm in the phase of filling the beans, which is 13 % higher than in the variant without fertilizers. The same tendency can be traced when determining the leaf surface area and accumulation of dry biomass according to the options in the observation phases. Thus, the best conditions for the yield formation were formed in the variant with the calculated dose for the planned yield of 5.0 t/ha. As a result, on average for 2 years, the soybean yield in this variant is 109 % higher than the control.

C помощью оптической микроскопии исследовано влияние воздуха, гелия, аргона, ксенона и гексафторида серы на целостность структуры льда, формирующегося при замораживании воды и ряда криозащитных растворов в температурном диапазоне от 0 до -50°С. Показано, что кристаллизация капли воды объемом ≈ 200 мкл в атмосфере воздуха происходит с нарушением целостности структуры льда. В замороженных образцах наблюдается образование газовых микропузырьков диаметром до 250 мкм. Продувка над поверхностью капли воды аргона, ксенона или гексафторида серы перед замораживанием позволяет снизить максимальный размер микропузырьков до 100 мкм. Продувка гелия над поверхностью воды, растворов DMEM и «ЕвроКоллинз» позволяет полностью устранить или значительно уменьшить образование газовых микропузырьков в процессе кристаллизации. Для формируемого при этом массива льда характерна тенденция к снижению вероятности растрескивания при охлаждении до -50°С, что может способствовать выживаемости биологического материала при консервации. Добавление криопротектора этиленгликоля в концентрации 1-10 об.% в раствор позволяет снизить или полностью предотвратить выделение микропузырьков газа при замораживании. Механизм, с помощью которого реализуется данный феномен, остается неясным. Добавление этиленгликоля в концентрации 10 об.% и более также предотвращает растрескивание льда при охлаждении до -50°С.

Методом циклической вольтамперометрии изучено электрохимическое поведение фенотиазинового красителя толуидинового синего в желатиновом гидрогеле в присутствии трипсина, пероксидазы и их комбинации. Показано, что содержащаяся в гидрогеле пероксидаза оказывает существенное влияние на электрохимические превращения толуидинового синего в течение первых 30 с измерений. Добавление трипсина усиливает эффект пероксидазного катализа. Экспериментально обоснована возможность одновременной оценки протеолиза и окислительно-восстановительного равновесия в модельной гидрогелевой системе при анализе вольтамперных кривых циклической вольтамперометрии. Полученные результаты обосновывают схему и принципы биоэлектрохимического моделирования диффузии электроактивных молекул в межклеточном матриксе.

Изучены физико-химические свойства липидов важнейших органов мышей (печени и головного мозга) после длительного приема в течение трех месяцев нанолипосомальных комплексов, состоящих из различных вариаций следующих веществ: фосфатидилхолина сои, эфирного масла гвоздики, рыбьего жира и казеината натрия. Из суммарных липидов органов готовили липосомы и определяли их способность к инициированному окислению, структуру липидного бислоя в областях локализации спиновых зондов 5-доксил и 16-доксил-стеариновых кислот, размеры и заряд липосом. Установлено, что все изученные параметры значительно изменялись с возрастом животных: способность к окислению уменьшалась в липидах из обоих органов; микровязкость уменьшалась, а структурированность возрастала; размеры липосом из липидов печени увеличивались, а из липидов головного мозга - уменьшались; применение диет приводило к приближению исследуемых величин к уровню, характерному для молодых животных. Установлена корреляция окисляемости липидов и их микровязкости с изменением состава жирных кислот, а размеров липосом - с параметром упорядоченности поверхностных слоев липидов.

С помощью спектроскопии комбинационного рассеяния исследовали изменения конформация гема и глобина гемоглобина при варьировании рО2 в среде инкубации эритроцитов и гемоглобина. При изменении pO2, в спектрах комбинационного рассеяния гемоглобина в эритроците и в растворе наблюдаются изменения ряда характерных полос как в области 1000-1700 см-1 (валентные колебания гема), так и в высокочастотной области спектра (2800-3000 см-1, валентные колебания аминокислот глобина). Установлено, что зависимость степени оксигенации гемоглобина (sO2), рассчитанной из параметров спектра комбинационного рассеяния, характеризуется S-образной кривой только для гемоглобина в эритроците. Установлено, что различия в конформация гема при изменении рО2 меняют его способность образовывать и комплексы с NO. При увеличении рО2 изменения конформация гема гемоглобина в клетке сопровождаются увеличением вклада боковых -СН3-групп колебаний полуколец пиррола и групповых колебания связей полуколец пиррола, а конформации глобина гемоглобина обусловлено увеличением вклада колебаний Н-метиновых групп и симметричных концевых метиленовых групп аминокислот.

Предложена новая математическая модель из тематики задач «хищник-жертва». Строго аналитически дан вывод системы нелинейных дифференциальных уравнений, качественно правильно описывающих динамику поверхностной концентрации населения Земли с учетом основных факторов «обрезания», влияющих на ее пространственно-временную эволюцию. С помощью предложенной модели показано, что вначале численность населения Земли имеет тенденцию к возрастанию, а затем, в силу открытости системы, после достижения максимума, начинает убывать. Этот факт подтвержден строгим математическим и численным расчетом.

Проблемы, связанные с природой жизни и способностью живого эволюционировать, в настоящее время привлекают внимание широкого круга ученых. Общее происхождение всех живых организмов делает затруднительным для биологов дать существенное определение жизни. Возможно, использование понятийного аппарата других наук способно разорвать этот логический круг. Тем не менее, биология может многое сказать о таких необычных и парадоксальных особенностях живого, как его специфическая устойчивость (способность к воспроизводству) и изменчивость. Чтобы описать, как такие явления могут быть возможны, может потребоваться разработка новых физических идей и моделей.
Geographic Isolation and Learning in Rural Schools
Authors: Bonilla-Mejía Leonardo , Londoño-Ortega Erika

Rural schools are usually behind in terms of learning, and part of this could be related to geographical isolation. We explore this hypothesis, assessing the effect of distance between rural schools and local governments on learning in Colombia. We use spatial discontinuous regression models based on detailed administrative records from the education system and granular geographic information. Results indicate that distance to towns and Secretary of Education has significant negative effects on students’ standardized test scores. We evaluated alternative mechanisms, finding that the effect of distance is partly explained by differences in critical educational inputs, such as teachers’ education attainment and contract stability. Finally, we assess the mediating role of a program providing monetary incentives to teachers and principals in remote areas.

Interest in the biosynthesis of silver nanoparticles (AgNPs) has been steadily increasing primarily due to their numerous applications in various fields, low-cost, use of non-toxic environmentally-friendly materials and easy implementation. This study focused on the biosynthesis of AgNPs using orange peel extract (OPE), optimization of process conditions, and application in catalytic degradation of methylene blue (MB) dye used in the textile industry. A central composite design in response surface methodology resulted in optimum conditions of 0.0075 g dry peel/mL for OPE concentration, pH of 11 and 1.5 mM silver nitrate concentration. The optimum conditions for the response variables corresponded to the peak absorbance of 0.79 and SPR wavelength of 403.8 nm in UV-vis spectra, and minimum particle size of 12.9 nm. In addition, peak absorbance and SPR wavelength appeared to be related to the size of the AgNPs. A full-factorial design for the catalytic degradation of MB dye by the biosynthesized AgNPs for 1 h indicated the maximum influence of AgNPs compared to the concentrations of MB dye and NaBH4 in decreasing order. The MB dye was reduced rapidly with NaBH4 in the presence of AgNPs due to their catalytic action. The findings of the study show the potential of OPE for the biosynthesis of AgNPs with excellent catalytic activity for the treatment of MB dye in industrial effluent.

Floods are one of the most devastating natural hazards, causing deaths, economic losses, and destruction of property. Flood susceptibility maps are an essential tool for flood mitigation and preparedness planning. This study mapped flood susceptibility using statistical index (SI) and weighting factor (WF) models in San Pa Tong District, Chiang Mai Province, Thailand. The conditioning factors used to perform flood susceptibility mapping were elevation, slope, aspect, curvature, topographic wetness index, stream power index, rainfall, distance from rivers, stream density, soil drainage, land use, and road density. The flood data were randomly classified as training data for mapping (70% of data) and testing data for model validation (30% of data). The results revealed that the SI and WF models classified 49.49% and 51.74% of the study area, respectively, as very highly susceptible to flooding. In the WF model, the factors with the greatest influence were land use, soil drainage, and elevation. The validation of the models using the area under the curve revealed that the success rates of the SI and WF models were 91.80% and 93.06%, while the prediction rates were 92.05% and 93.52%, respectively. The results from this study can be useful for local authorities in San Pa Tong District for flood preparedness and mitigation.

Background: Spontaneous pneumomediastinum or mediastinal emphysema is relatively a rare disease that occurs in viral and bacterial infections with the benign entity. Case: The patient was a 57-year-old man who, after a week of self-isolation at home, coming to the COVID-19 triage center of the hospital with severe shortness of breath. He was admitted to the Intensive Care Unit (ICU) due to acute respiratory failure. The patient was treated as the protocol designed and respiratory support with high flow nasal oxygen and Non-Invasive Positive Pressure Ventilation (NIPPV). Spontaneous pneumomediastinum was developed during viral pneumonia infection. The known risk factors included age, male sex, and abnormal laboratory finding. All the biochemical and hematological findings such as lymphopenia, thrombocytopenia, raised CRP, LDH, and ferritin were detected in our cases. They indicate a possible prognosis for the development of acute respiratory failure and adverse clinical outcomes. Conclusion: Spontaneous pneumomediastinum has usually a benign outcome in COVID-19 Pneumonia and its prognosis is related to background conditions in patients.

Background: Spermatogenesis associated 19 (Spata19) was introduced as a testis-specific gene that was probably involved in spermatogenesis cell apoptosis. Therefore, this study aimed to investigate the effect of Spata19 inactivation on sperm count. Materials and Methods: We generated global Spata19 knockout mice by CRISPR/Cas9 nickase technology. Disability was validated in three levels of DNA, RNA, and protein using PCR, RT-PCR, and immunohistochemistry. Histological studies were performed for testis. Sperm characteristics were also assessed with CASA software. Results: Spata19 knockout mice had a 43 nucleotides deletion in exon 4 of this gene. The presence and absence of Spata19 were confirmed in normal and knockout mice, respectively. The presence of Spata19 in normal NMRI mice was detected in the brain, heart, and thymus by semi-nested RT-PCR and in Leydig cells by immunohistochemistry. Histological studies revealed a decrease in sperm count in knockout mice. Also, CASA parameters were significantly reduced (P<0.05). Conclusion: These data indicate that Spata19 inactivation is a cause of oligospermia, and its role could be beyond an adhesive molecule.

Background: Vitamin D plays a key role in the modulation of numerous immune functions against infectious agents. We aimed to explore the association between serum 25‑hydroxyvitamin D (25[OH] D) levels and cytokine responses, along with hematological changes, in patients with urinary tract infection (UTI). Materials and Methods: Vitamin D level, cytokines (interferon [IFN]−γ, interleukin [IL]−4, IL−6, IL–10, IL−17A, tumor necrosis factor [TNF]−α, and transforming growth factor [TGF]−β), hematological indices (neutrophil-to-lymphocyte ratio [NLR], monocyte-to-lymphocyte ratio [MLR], neutrophil-to-monocyte ratio [NMR], platelet-to-lymphocyte ratio [PLR], and mean platelet volume [MPV]), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were evaluated in a case-control human study included 65 patients and 45 controls. Results: Among the enhanced cytokine levels in patients, the cytokines IFN-γ, IL-17A, and IL-10 had a significant association with 25(OH)D, but not IL-6, TNF-α, and TGF-β. The IL-4 levels remained unchanged. By comparing hematological indices, we found the association of increased NLR and MLR with 25(OH)D and the cytokines IFN-γ and IL-17A, along with a decrease in the PLR without showing such an association. The NMR did not show any significant difference. The platelet count showed an association with IL-6, IL-17A, and TGF-β, but the association of MPV with 25(OH)D was significant. The ESR results exhibited statistically non-significant differences. CRP elevation was directly associated with IL-6 and IL-17A, but not with 25(OH)D. Conclusion: 25(OH)D-mediated inflammatory cytokine milieu might alter the proportion and function of peripheral blood cells in a regulated manner to support bacterial clearance which needs further studies to be validated.

Objetivo: Esclarecer as principais indicações de uso terapêutico do ECMO (Oxigenação por Membrana Extracorpórea) em pacientes portadores do vírus Sars-CoV-2. Métodos: Esta pesquisa configura revisão bibliográfica do tipo integrativa baseada na análise de 11 artigos disponíveis no Portal da Biblioteca Virtual em Saúde (BVS) e em seus sites aliados, mediante aplicação de fórmula de busca pautada no vocabulário disponível no DeCS (Descritores em Ciências da Saúde). Resultados: Dentre os 11 estudos selecionados, 36,36% (n=4) evidenciaram que a principal indicação para o uso de oxigenação por membrana extracorpórea (ECMO) em pacientes com COVID-19 é a presença de hipoxemia refratária aos suportes respiratórios padronizados, tais como ventilação mecânica protetora pulmonar, recrutamento pulmonar, posicionamento prono, bloqueio neuromuscular e sedação. No que se refere ao uso da ECMO em pacientes portadores de Sars-CoV-2, 18,18% (n=2) dos artigos abordaram o uso da técnica citada em pacientes pediátricos e atestaram, em relação às indicações, que a grande maioria das diretrizes hospitalares utiliza as mesmas indicações para ECMO em pacientes com COVID-19 e para outras doenças virais, quais sejam: hipoxemia refratária e agravamento da hipercapnia, SDRA (Síndrome do Desconforto Respiratório Agudo) ou necessidade contínua de drogas vasoativas secundárias ao agravamento do quadro viral. Conclusão: Estudos em ambiente de terapia intensiva demonstraram taxas de mortalidade discretamente menores em pacientes com SDRA por infecção pelo COVID-19 que fizeram uso de ECMO, em comparação à terapia respiratória convencional.

Toksoplasmosis disebabkan oleh parasite Toksoplasma gondii yang menginfeksi sekitar 30% populasi manusia di seluruh dunia. Oleh karena itu penelitian ini bertujuan untuk mengidentifikasi faktor risiko dan karakteristik penderita toksoplasmosis berdasarkan faktor demografi, keberadaan hewan peliharaan, serta kondisi hygiene dan sanitasi yang bermanfaat untuk deteksi dini dan pencegahan penyakit melalui desain case control dengan menentukan kelompok kasus dan control pada wanita sudah menikah dan pernah berobat dan konsultasi di Klinik Pengobatan Alternatif Yayasan Aquatreat Therapy Indonesia  di Kota Bogor selama tahun 2019. Hasil analisis chi-square menunjukkan bahwa keberadaan hewan peliharaan (kucing p=0.007 OR=3.183, anjing p=0.030 OR=5.571  dan burung p=0.001<0.05 OR=5.690) dan factor hygiene dan sanitasi berupa kebiasaan tidak memakai alas kaki ketika diluar rumah (p=0.008 OR=0.211)  secara signifikan berhubungan dengan toksoplamosis. Sedangkan faktor demografi serta factor hygiene dan sanitasi berupa cuci tangan dan kaki setelah beraktivitas, sumber air minum, kontak tanah, berkebun dan jenis pemukiman  tidak berhubungan  dengan toksoplasmosis. Hasil analisis regresi logistic menunjukkan variable kebiasaan tidak memakai alas kaki ketika diluar rumah (p=0.011 OR=4.684 CI =1.423-15.418 dan kepemilikan burung (p=0.001 OR= 0.177 CI=0.062-0.510) sehingga dapat disimpulkan bahwa kebiasaan tidak memakai alas kaki ketika diluar rumah merupakan factor risiko tertinggi yang dapat meningkatkan risiko terjadinya toksoplasmosis 4-5 kali lebih besar.
Multilingualism in Under-resourced Languages for Sustainable Development in Rural Communities
Authors: Ojong Diba Rachel Ayuk
Published: August 2021

Cameroon, a central African country, is one of the most linguistically diverse countries in Africa with about 280 living languages (Ethnologue 2020), for an estimated population of 26,727,521 people (Worldometer, 2020). Cameroon is second only to Papua New Guinea in terms of its multiplicity of languages for a relatively small population. Contrary to popular opinion, multilingualism exists even in rural communities; in fact, it is even more intense. In Lower Fungom, an incredibly linguistically diverse rural community in the Northwest region of Cameroon, high rates of individual multilingualism are the norm; it is common to find individuals who use more than seven distinct native languages to navigate through their daily lives. However, this multilingualism is usually neglected as a resource by foreign experts in the transmission of knowledge in linguistically diverse communities such as Lower Fungom. In their attempt to transmit knowledge in almost all ramifications including in the global pursuit of sustainable development, experts foreign to the target community typically focus only on the ‘understanding’ of their message, meanwhile ‘understanding’ could be totally inconsequential as far as the acceptance of a people is concerned. Sustainable development with trends away from the (socio-cultural and linguistic) norms of a community would be a complete farce. This paper aims at highlighting two key features indispensable for development to be extended to rural communities in Cameroon and for it to be sustainable. These aspects are the active collaboration with community members to obtain culturally appropriate interpretations and the use of all the languages existing in the community in transmitting knowledge. Data for this paper comprises recorded natural speeches, interviews, and observation notes due to prolonged stays in the area and resultant informal discussions with its indigenes. This study will not only add to the handful of studies on rural multilingualism. It will not also only promote multilingualism that has become an endangered practice, but it will also be a crucial addition to efforts of sustainable development in Cameroon.

The purpose of this study is to examine Lean implementation at an manufacturing company. Three of the main factors that prompted the company to undertake the Lean journey are product quality, employee satisfaction and flow. This is a case study conducted with qualitative research methods and analysis of company data. Semi-structured interviews were conducted with employees that were purposively chosen for the task. Company data was also be studied for numerical results relating to the study. Primary results indicate that a significant change has occurred in two of the three factors measured. Flow and employee satisfaction have both improved. The study does not indicate that product quality has improved in regard to the Lean implementation. The results also show that the main obstacles in the Lean implementation are employee training, company culture and internal flow of information.

Green roofs are increasingly being installed cities in Europe as a part of sustainable stormwater systems. The goal of this research was to assess the hydrological efficiency of different configurations of extensive green roofs in Iceland and present suggestions for successful design of such roofs based on local materials and weather conditions. International literature and best design practices were reviewed. Runoff from five test roofs was monitored for 11 months, in conjunction with snowdepth, rainfall, wind and air temperature. Green roof water retention measured highest 85% in June and July in accordance with other studies in cold climates. Water retention measured, however, somewhat lower during the winter (<20%). Significant delay of runoff's center of mass and lowering of peak runoff was measured in all green roofs except during the largest runoff events. Average event water retention was correlated to air temperature, cumulative rain, rain 14 days before event and wind speed 7 days before event. Roofs with moss and sedum turf demonstrated good hydrological efficiency, good appearance and needed little maintenance. Grass turf roofs retained slighlty more water, but were less drought resistant and looked poorly during early summer. Wild, water resistent plants like moss and sedum performed better overall.

Automated vehicles (AVs) are sometimes considered a silver bullet for contemporary transport problems. For particular scenarios, the technology is believed to have many advantages, such as improving the accessibility of underserved populations. However, the technology may also lead to lesser consequences under other scenarios, with some simulations predicting increase in congestion as the modal split shifts towards automation. In any case, the mode choice shift will not be realised without the public acceptence of AVs.

The public opinion towards the technology has not been fully explored, and particularly not in Iceland. This article focuses on the Icelandic results of a cross-national survey. 561 valid responses were recorded, considering attitudinal and stated-mode-choice questions and the responses then analysed as per the sample‘s socio-demographic attributes and compared to a similar survey performed in other european countries.

The Icelandic public is generally more positive towards automated vehicles than other Europeans, however still skeptical. At the same time as AV passengers feel more safe than vulnerable road users in the vicinity of an AV, AV passengers also feel more safe with an AV supervisor inside the vehicle. It is uncertain whether people will use the vehicles for pick-up and drop-off of children. Respondents are generally more positive that their goods be transported in AVs instead of people. In spite of this, 70% of respondents were positive that the technology be tried in their neighborhood and 60% of respondents are positive towards trying the vehicles themselves. Further research is suggested in the outlook of the articles, based on indices and further metrics.

Este artigo fornece uma breve história da segurança de informação, com ênfase nas ameaças à segurança cibernética e como estas são influenciadas pela globalização. É realizada uma análise comparativa de três fontes diferentes para captar alguns padrões sobre esta relação: 1) relatórios da ENISA sobre ameaças cibernéticas, 2) relatório global de riscos, sobre ameaças globais e 3) relatório DHL – Global Connectedness para indicadores de globalização. Para evitar dispersão, a análise é circunscrita aproximadamente à última década. Este relatório aponta para uma intensificação das ameaças cibernéticas nos últimos anos, enquanto os indicadores de globalização sugerem um abrandamento nas interligações globais. São recomendadas para investigação adicional algumas hipóteses para explicar estes padrões
Information and security in cyberspace: The influence of globalization on the intensification of risks and threats in the last decade

Published: August 2021

This article provides a brief history of information security, with emphasis on cybersecurity threats and how these are influenced by globalization. A comparative analysis of three different sources is conducted to capture some patterns about this relationship: 1) ENISA reports on cyberthreats, 2) The Global Risks Report, on global threats and the 3) DHLGlobal Connectedness report for globalization indicators. To avoid dispersion, the analysis is circumscribed roughly to the last decade. This report points to an intensification of cyber threats in the last few years, while the globalization indicators suggest a slowdown in global interconnections. A number of hypotheses to explain these patterns are recommended for further research.
Buscando uma Gestão Eficiente para o Judiciário: Uma Agenda em Construção?
Authors:   Universidade do Sul de Santa Catarina, Brasil, Salazar Clarissa
Published: August 2021

A proposta deste ensaio teórico é fazer uma reflexão sobre a atual discussão acerca da gestão do Poder Judiciário. Vive-se um momento de rutura, num cenário de desproporção entre a oferta de serviços e a quantidade de conflitos a serem sanados. A coprodução tem sido defendida como uma alternativa através da participação dos utilizadores destes serviços na tomada de decisão. Para esta discussão, traz-se a Nova Gestão Pública que propõe reformas a partir da mesma lógica de ação que rege as empresas privadas. E o Novo Serviço Público, que defende a produtividade e a eficiência num contexto maior de democracia e interesse público. Conclui-se que não há um pensamento dicotómico ao se construir um modelo de gestão coerente com as dificuldades e a complexidade da prestação jurisdicional. Há sim rutura com o passado engessado, busca por uma nova identidade, sem perder a sua legitimidade e compromisso com os princípios democráticos.
