Coronal mass ejection and solar activity for cycle 23 and 24; a comparative analysis of observational parameters
Authors: AO Umuogbana , CC Onuchukwu
Published: March 2023

We analyzed sunspot tracers [sunspot number (SSN) and sunspot area (SSA)] and Coronal Mass Ejection (CME) observed parameters for cycle 23 and 24, comparing sunspot tracers time series with time series for CME parameters [Initial speed and Acceleration] for All and segregated CMEs for possible similarities in their variation pattern. A comparison of CME time series with solar activity (especially SSAT and SSN which seem to reflect the true general activity cycle) shows that fast CMEs follow the solar activity cycle but slow CMEs don’t. Also, CMEs with positive and negative acceleration follow the solar cycle but lags behind b 3monhs for cycle 24. However, the CME acceleration does not follow the solar cycle. CME distribution show that Slow CMEs increases in initial speed from one cycle to the other with a corresponding decrease in acceleration for CMEs with fast speeds. There is an almost insignificant increase in acceleration for CMEs with positive and negative acceleration. These charges are perhaps due to effect of solar wind.
On the temperature of the solar corona
Authors: Akasofu Syun-Ichi
Published: March 2023

It has long been considered that the high temperature of the solar corona, inferred from the presence of highly ionized atoms such as FeXIV, is caused by various heat transfer processes from the photosphere. In this paper, it is suggested that the neutral hydrogen layer, containing Fe atoms, of the corona, are ionized by the impact of energetic current carrying electrons along loops of magnetic field lines. It is suggested that current-carrying electrons are accelerated by the double layer; the corona consists of a large number of magnetic loops. It is shown that the current of intensity of about 1μA/cm2, consisting of 10 Kev electrons accelerated by the double layer, could provide the ionization rate of 1.8 x 104/cm3 in the corona along the loops. Thus, the corona could not be in a thermal equilibrium, so that the temperature of the corona may not be inferred from what the ionization potential of highly ionized atoms suggests. It is shown also that a dynamo process of the photosphere can generate the needed field-aligned currents. Further, the above estimated ionization rate can supply the solar wind.

Underweight and Normal Weight Central Obesity Among Filipinos and its Association with Cardiovascular Risks and Diseases
Authors: Toledano Bryan Rene F , Vilela Gerald C
Published: March 2023

In most epidemiological studies underweight and normal weight central obesity groups are either underrepresented, excluded, or merged to the normal weight category. This study aims to compare underweight and normal weight central obesity groups and possible age and gender differences in association with cardiovascular risk and diseases using a previous local study. Methods: Participants were Filipinos aged 20 years or older who had participated in and completed the desired data in the National Nutrition and Health Survey 2008. Participants were categorised into two groups: underweight and normal weight central obesity. The profiles of the groups were compared and their association with cardiovascular risks and diseases determined, using adjustment models for age and sex. Results: A total of 3,009 participants were included in this study: 684 (22.7%) underweight and 2,325 (77.3%) normal weight central obesity. The mean age for underweight participants was 47.8 years versus 43.2 years for normal weight central obesity; 56.6% of the participants were female and 43.4% were male. In comparison to normal weight central obesity using adjustment models for age and sex, ORs were as follows: hypertension OR 1.49, diabetes OR 1.71, and dyslipidaemia OR 1.8. Using a sex stratified model there were significant differences in diastolic blood pressure (mean, male 78 versus female 75), triglycerides (mean, male 117 versus female 106), HDL level (mean, male 40.3 versus female 41.6) and LDL level (mean, male 99 versus female 115). Using an age stratified model, coronary artery disease ORs were 25th percentile (OR 2), 50th percentile (OR 2.4) and 75th percentile (OR 1.9); cerebrovascular accident 75th percentile (OR 2.5) and peripheral artery disease 50th percentile (OR 3.4). Hypertension 25th percentile (OR 2.0), 50th percentile (OR 2.4) and 75th percentile (OR 1.9); diabetes 25th percentile (OR 6.7), 75th percentile (OR 1.7) and dyslipidaemia 25th percentile (OR 1.2) were significantly higher in the underweight group. Conclusion: Greater association in hypertension and coronary artery disease in all age groups, stroke among the older age group, and diabetes among the younger and older age groups were seen among underweight participants compared to normal weight central obesity among Filipinos.

Authors: Kusuma Citra Aditya , Abid Abid
Published: March 2023

Purpose: The study reported in this article sought to examine the current state of Botutonuo Beach in the Province of Gorontalo, Indonesia, and develop a digital-based marketing strategy that allows attractions of the beach to be open to potential worldwide tourists. The beach is a popular tourist destination in the province, yet limited information about the beach is available online.

Design/Method/Approach: A design-based research method was employed in the study. To collect data, observations and semi-structured interviews with four locals who were also organizing the beach were used; while for the analysis, a thematic analysis approach was utilized.

Findings: Findings revealed three main themes that best describe aspects of Botutonuo Beach tourism sites that need improvement, namely accessibility, facilities, and convenience, as well as showed what important information that needs to be included on the beach website.

Practical Implications: It is expected that the website can be used by the beach management and local government to foster the promotion of Botutonuo Beach. It is also hoped that the findings, in general, may encourage active participation by the beach visitors and local government to ensure effective management of the beach so that national and international recognition can be obtained.

Originality/Value: The study proposed development of a website that helps in promoting Botutonuo Beach as one of the popular tourist destinations in Gorontalo.

Research Limitations/Future Research: Future research examining the efficacy of this website development is a potential research topic to undertake.

Paper Type: Empirical

JEL Classification: L29, M31, Z33

Botutonuo Beach is a popular tourist destination in the Province of Gorontalo, Indonesia. The locals have primarily been managing the beach for years; however, very little information can be elicited about it online by target visitors from other regions. Therefore, the study reported in this article sought to examine the beach’s current state and develop a digital-based marketing strategy that allows attractions of the beach to be open to potential worldwide tourists. Using a design-based research method, data were collected using observations and semi-structured interviews with four locals who were also organizing the beach. To analyze data, a thematic analysis was used. Findings revealed that several things related to accessibility, facilities, and convenience were crucial aspects to be considered by the beach management. Furthermore, developing a website that helps the management promote the beach’s uniqueness is necessary. The study suggests that the locals, visitors, and government share the responsibility to ensure more effective beach management.
The Effect of Public and Private Sector Fixed Capital Investments on Gross Domestic Product and Employment in Turkey
Authors: Giray Filiz , Ömür Özgür Mustafa
Published: March 2023

Purpose: The aim of this study is to analyze the effects of public and private sector investments on gross domestic product (GDP) and employment econometrically with the panel data method in order to determine the efficiency of investments in Turkey.
Design/Method/Approach: In the study, the possible effects of public and private sector investments on GDP and employment in Turkey are examined by dividing them into sectors. Sectors are included in the analysis as agriculture and other non-agricultural sectors. Since the data of various sectors within a certain time period are used, time series and horizontal cross-sectional data are analyzed using the panel data method, which allows them to be used together. Four different models are created in the research. Among them, the effects of public investment expenditures on GDP in the period of 2004-2020 in Model 1, private investment expenditures on GDP in the same period in Model 2, public investment expenditures on employment in the period of 2014-2021 in Model 3 and private investment expenditures on employment data in Model 4 are investigated.
Findings: The results obtained from the analyses show that public and private sector investments have a significant and positive impact on GDP and employment in Turkey.
Practical Implications: It is generally accepted in the public finance literature that investments will positively affect economic growth, production level, employment and regional development if they are used in productive areas.
Originality/Value: What makes this study different from others is that the relationship of public and private sector investments with both GDP and employment is analyzed separately. In this way, a comparison can be made from the point of public and private sector investments in Turkey in terms of the contribution of investments to both GDP and employment, and an answer can be sought to the question of how correct the policy of increasing the share of the private sector in investments, especially in recent years, is in Turkey.
Research Limitations/Future Research: This study will make a significant contribution to the literature on the economic effects of public and private sector investments. It will be determined how accurate the idea of increasing the share of private investments in Turkey in recent years is. According to the results obtained from the study, new studies will be conducted on what can be done to increase the efficiency of public or private sector investments.

Soconusco, una zona de producción afluente en el Sistema Mundo Mesoamericano
Authors: Navarro Castillo Marx
Published: March 2023

La región del Soconusco en el estado de Chiapas, México, desde el siglo XIX, ha sido objeto de estudio por parte de los especialistas arqueólogos. Diversas han sido las investigaciones realizadas en la región; la presentada aquí se enfoca en el período Clásico, sobre todo en lo que respecta al papel desempeñado en lo que algunos autores han denominado el Sistema Mundo Mesoamericano. Es a partir del estudio realizado por el tipo cerámico conocido como plomizo, identificado en lugares tan lejanos como Nayarit (oeste de México) hasta Costa Rica y desde Monte Albán hasta Tula, que nos permite apuntar que existieron redes de interacción bien establecidas las cuales permitieron la movilización de dicho bien. El área estudiada por el Proyecto Arqueológico Costa del Soconusco (PACS) ha identificado los lugares de producción de la cerámica plomiza y con ello se han propuesto relaciones jerárquicas y de comercio no solo a nivel local o regional, sino panmesoamericano. Esta clase de interacciones pueden ser entendidas en términos del Sistema Mundo que, si bien fue acuñado para entender los procesos económicos actuales, sin duda puede ser utilizado para entender las sociedades antiguas. Este acercamiento pone de manifiesto la esencia misma de la arqueología, la cual, debido a lo reciente de la disciplina, tiende a utilizar términos creados en otras áreas de investigación; esto representa su carácter multidisciplinario. Por ello, la propuesta de este artículo sobre el Soconusco como zona de producción afluente desde el período Clásico, tomando como fuente principal la distribución de la cerámica plomiza a lo largo de Mesoamérica.
‘Yes, we’re done’ – ‘except Ricardo’

Oral argumentations among peers always involve negotiation of group identity. By means of multimodal analysis, this case study shows how children mobilize interactional space, physical surroundings, as well as verbal and paraverbal resources for the embodied enactment of in- and exclusion, of affiliation and disaffiliation, and the negotiation of group identity. We argue that the processing of interpersonal relationships constitutes a crucial aspect of oral argumentation skills and that in particular multiparty interaction provides an indispensable source for the study of oral argumentation and its acquisition. The example analysed is a conversation among four elementary schoolchildren (8 years) working on a cooperative decision task. The conversation is characterized by the consolidation of a 3 versus 1 constellation, ultimately preventing the group from reaching a consensual decision.
Romanian migrant families in Castelló de la Plana (Spain)
Authors: Amorós-Negre Carla
Published: March 2023

This article adopts the critical and ethnographic language policy approach (McCarty, 2011; Johnson and Ricento, 2013) to unveil the family language policy adopted by first-and second-generation Romanian parents in a diasporic context, Castelló de la Plana, the capital city of the Castelló province (Spain). The study focuses particularly on parents’ language ideologies and practices regarding the acquisition and use of Spanish, Catalan, and Romanian. The analysis of parental policies is pursued through 15 semi-directed interviews about life experiences produced in ethnographic research. By drawing on biographical narratives, I examine in detail how parents ground their position regarding language choices, transmission, or interruption of the home language and how multilingualism is perceived and valued by different generations. I conclude that first- and second-generation migrant parents mobilise different language ideologies in relation to the use of the heritage language and the translingual practices they deploy. I also report on the tensions migrant families experiment regarding languages in this neoliberal economic governmentality (Martín Rojo, 2019) and how language policy at the family level sometimes supports and reproduces the institutional discourses and hegemonic nation states’ policies and at other times challenges them.
AN IMPACT OF PUBLIC POLICY ON THE FINANCIAL PERFORMANCE OF PUBLIC INSTITUTIONS
Authors:   University of Tuzla, Bosnia and Herzegovina, Cergic Fuad
Published: March 2023

Each country pays great attention to the public sector both in terms of the budget and its impact on social life, macroeconomic stability, employment and in general on the national economy. An analysis of the impact of public policies is very important for decision - makers to understand what kind of wanted and / or unwanted effects these policies bring, and it is particularly important to understand what effects will be on the performance of public institutions. Public policies are basis of each community whether it is a unit of local self-government or the entire state. Without well-established public policies, we cannot expect the effective functioning of any community. The general aim of the research is to determine an impact of different types of public policy on the financial performance of public institutions

Asia has been the region with the world’s fastest growing economies in decades, and it continues to lead global growth in the future. The rapid economic growth has led to a huge demand for energy. However, this problem faces enormous environmental problems, climate change and global warming, in particular. Therefore, the transition energy from traditional energy to clean energy sources, renewable energy is imperative and to be inevitable trend in the future. With cleaner properties than oil and coal, natural gas can be seen as an important bridge in the transition energy process towards a low-carbon economy in Asia. Despite the fact that there are a lot of controversies and uncertainties about the development of natural gas in Asia, there are many reasons for us to believe that natural gas will play an important role in the energy mix in Asia in the future, such as the development of unconventional gas, the development of natural gas and LNG markets, environmental and climate policies, or the decline in energy prices. This paper will show the favorable condition to explain why natural gas can play an important role in the energy transition in Asia.

PORE-SCALE SIMULATION OF MULTI-COMPONENT GAS DIFFUSION IN THE CARBON XEROGEL NANOPOROUS STRUCTURE USING LATTICE BOLTZMANN METHOD
Authors: Dai Jia-Peng , Li Dong , Cao Zhan-Wei , Xu Xiao-Liang , He Ya-Ling
Published: March 2023

The gas diffusion in the carbon xerogel nanoporous structure is studied at the pore-scale using the lattice Boltzmann method in this paper. The carbon xerogel has been reconstructed by an improved diffusion-limited, cluster-cluster aggregation method, and the physical properties of the reconstructed nanoporous structure, including the porosity, the effective pore volume, and the pore size distribution, agree well with the experimental data. The diffusion of multi-component gas in the carbon xerogel nanoporous structure has been simulated. The results show that the diffusivity for argon in the carbon xerogel nanoporous structure is much slower than that for nitrogen and air. Therefore, argon is a better option to be pre-filled into the carbon xerogel to prevent its structure from ablation. Besides, a correlation to predict the required time for the gas concentration in the carbon xerogel reaching a certain value has been developed, and the correlation could offer reliable guidance to help the design of thermal insulation systems which are based on carbon xerogels.

Published: March 2023

Le traumatisme thoracique pénétrant par arme à feu est une pathologie rare en France et sa mortalité préhospitalière est élevée. Nous rapportons ici le cas d’un jeune homme présentant une plaie cardiaque causée par un plomb de carabine. Le patient s’était spontanément présenté aux urgences d’un Hôpital d’instruction des armées qui ne possède pas le plateau technique adapté. La prise en charge initiale a été réalisée par le médecin militaire de garde à l’aide de l’algorithme « MARCHE », utilisé dans les forces armées pour les blessés au combat. Le diagnostic a été rapidement posé grâce à une radio thoracique de face et à l’eFAST échographie. La collaboration avec le centre hospitalier universitaire voisin a permis de réaliser dans les plus brefs délais la confirmation par angioscanner thoracique ainsi qu’une évacuation pour réaliser la prise en charge chirurgicale adaptée. Ce dossier nous rappelle qu’il ne faut pas sous-estimer la gravité d’une plaie pénétrante provoquée par une carabine à plomb, qui est une arme à feu en vente libre. Il illustre également la nécessaire coopération interhospitalière sur les territoires afin d’orienter rapidement les patients complexes dans les filières techniques adaptées.
Diagnostics trompeurs de tableaux cliniques abdominaux fréquents en médecine des forces
Authors: DE MARTENE Hugues , COLLEONY Thomas , AIGLE Luc , MARSAA H.
Published: March 2023

La pratique de la médecine en situation isolée, en opération extérieure comme dans les centres médicaux des forces pré-positionnées, peut s’avérer être un exercice délicat. Un tableau clinique typique ne doit pas faire poser un diagnostic présomptif de façon irrévocable. Le respect des recommandations de bonnes pratiques doit rester la règle, permettant de redresser certains diagnostiques rares. Nous rapportons deux tableaux cliniques abdominaux rencontrés fréquemment en soins primaires. L’un est une douleur aiguë de la fosse lombaire avec hématurie microscopique et l’autre est une douleur de la fosse iliaque gauche. Les diagnostiques n’ont pas été ceux escomptés par la présentation clinique et l’argument de fréquence. Ce qui apparaissait comme une crise de colique néphrétique s’est révélée être un hématome spontané de la surrénale, tandis que la suspicion de diverticulite colique était en fait une appendagite épiploïque. Malgré les difficultés d’accès aux examens complémentaires, le suivi des recommandations en termes d’imagerie permet de redresser le diagnostic, sans nécessairement modifier la prise en charge, du moins initialement.

In this study, we aimed to compare survival outcomes after receiving radiofrequency ablation (RFA) and hepatic resection (HR) for solitary hepatocellular carcinoma (HCC) with stratification by tumor size and age. A retrospective cohort was obtained from the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015. Patients were grouped by tumor size (0-2, 2-5, and > 5 cm) and age (>65 and ≤65). Overall survival (OS) and disease-specific survival (DSS) were assessed. For patients >65 with tumors measuring 0-2 and 2-5 cm, the HR group had better OS and DSS compared with the RFA group. For patients >65 with tumors > 5 cm, OS and DSS did not differ significantly between the RFA and HR groups (p = 0.262 and p = 0.129, respectively). For patients ≤65, the HR group had better OS and DSS compared with the RFA group regardless of tumor size. For patients with resectable solitary HCC, regardless of age, HR is the better choice not only for tumors ≤ 2 cm, but also for tumors 2-5 cm. For resectable solitary HCC with tumors ＞5 cm, HR is the better choice for patients ≤65 but for patients >65, the issue of treatment choice needs to be further studied.
PRICE TRANSMISSION OF MELONS (CUCUMIS MELO AND CITRULLUS LANATUS) IN MYANMAR – CHINA BORDER TRADE
Authors: Lwin Wuit Yi , Brorsen Wade , Henneberry Shida Rastegari
Published: March 2023

Border trade is the main export channel for agricultural products from Myanmar (formerly Burma). With an increasing quantity and value of exports during the last few decades, melons have become one of the major crops in the national export strategy of Myanmar. In this paper, the word “melons” is used to represent both watermelon (Citrullus lanatus) and muskmelon (Cucumis melo) cultivars. No previous research exists on price transmission between these countries, especially for the horticultural produce market. This study aims to measure the magnitude and speed of spatial price adjustment in melons exported from Myanmar to China. Price transmission in the melon export market in Myanmar is analyzed by studying the lead-lag relationship among prices in the border market in Myanmar and the selected wholesale markets in Beijing, China, using a vector autoregressive model (VAR). Prices are transmitted quickly from Myanmar to the selected wholesale markets in Beijing, China. The wholesale market price in Beijing, China lags only one day behind the Myanmar price. In the Myanmar border market, the melon price is affected only by its own lagged price. The adjustment of melon prices in one day suggests that market information is getting passed up the market channel, and there does not appear to be a need for a policy to improve market efficiency.

Published: March 2023

Wetland is particularly important in developing countries for economic purposes. This study examines livelihood activities, wetland dependence and its determinants among wetland households. Primary data were collected from households in a two stage random sampling procedure. Both descriptive and quantitative methods were employed for data analysis. Results show that support for dry season production, all year round water supply, and fishing were the first, second and third most important benefits of wetland to households. Socio-economic factors have influences on wetland dependence. This study concludes that wetland support dry season farming and is heavily depended upon for income by households in wetland communities. It is therefore recommended that skills acquisition centres should be established in wetland communities to engage youths particularly male in other employment apart from wetland related ones so as to reduce dependence on wetlands and thus take pressure off them.

Published: March 2023

The paper is dedicated to issues on analysis of providing of personal data protection by Public Authorities under conditions of the war. It was noticed, that under conditions of wide-scale military aggression, an appropriate attention has to be paid to issues on military personnel personal data protection, as an unauthorized access to these personal data may be dangerous for the life of military personnel. There is outlined, a significant condition for providing of personal data protection has to be a control of information environment. It must stop uncontrolled posting on social networks of numerous pages with photos and videos of Ukrainian military prisoners with their personal data. These measures have features of anti-Ukrainian propaganda; also, they violate rights of military prisoners, including rights for personal data protection. Receiving the access to personal data of military prisoners, the enemy can use these data to intimidate relatives or State Authorities of Ukraine, to expand panic, or for others hybrid means of informational elements of the war. To provide military personnel personal data protection, it is necessary to work-out particular information registers of categories of persons, mentioned above and to provide different levels of access to its. However, it is necessary to regulate possibilities of receiving information about subjects that are included into the data base, or vice versa, receive an information about absence of data about specific persons. It allows to prevent to violations of rights of military personnel. The issue on determination of competencies of State Authorities in the field of providing of personal data protection of citizens in conditions of the war requires to be resolved. The establishing of Interdepartmental Coordination Center for Registration, Exchange and Return of Prisoners, Missing and Dead is suggested.

Prognostic modeling of urbanized territory should be an integral component of military and geographical analysis of operational-strategic direction. In the absence of sufficient information from various means of intelligence, forecasts, including long-term ones, can significantly increase the reliability of information in the decision-making support system. Based on this, the methods of mathematical-cartographic modeling have the right to exist in such system as an additional source of prognostic information. From all variety of methods of mathematical-cartographic modeling, the method of cellular automata was chosen for study, as a discrete in time, dynamic in space and multifactorial process. Thorough analysis of literary sources, which determine the state and modern trends in development of cartographic modeling of territorial development of cities in the world, was carried out. The place of the method of cellular automata in the system of mathematical- cartographic modeling as tool for creating prognostic models of dynamics of spatial distribution of phenomena is determined. The structure of spatial database of mathematical-cartographic modeling of the territorial development of Ukrainian city Dnipro has been developed. Local transition functions are constructed that determine the relationships between single cellular automata in the raster surface of simulation. A software application was developed in high-level Python general-purpose programming language, integrated into the environment of ArcGIS geoinformation system, and modeling of territorial development of city Dnipro was carried out. As a result of modeling, scenarios of the city's development for the next five and ten years were obtained. The growth of the area of territorial development of city Dnipro in the next five years may amount to seventy-two square kilometers, and in the next ten years – one hundred and twelve square kilometers. In total, the expansion of the city territory by one hundred and eighty-four square kilometers is predicted, which will ensure its total increase by forty-four percent.

The tree species Genipa americana ('Jenipapo') is found in the Brazilian Cerrado. It is economically important for its wood and fruits, used in traditional medicine and in the recovery of degraded areas. Based on the multiple uses of this species, we aimed to analyse the effect of different fertilisers (including a control [without fertilisation]) and chemicals (NPK = nitrogen, phosphorus and potassium chloride), both organic (vermicompost) and mixed (NPK + vermicompost), on early field growth and secondary metabolite production in young and mature G. americana leaves for 12 months, with monthly collections. The growth analysis indicated that the species develops better in fertilised soils in terms of the height and diameter of the collar, in relation to the control, with the different types of fertilisation presenting equivalent results. Therefore, it is suggested that in the reforestation of degraded areas, such as the Brazilian Cerrado, fertilisation is necessary for ‘Jenipapo’ planting as an alternative to reduce the degradation levels in this region. The same pattern was found in the analysis of the metabolic classes and the frequency of the treatment compounds, with a predominance of phenolic and flavonoid compounds in young and mature leaves. Only a different pattern was found for NPK + vermicompost, with a greater intensity of tannins and cardiotonic heterosides. The use of leaves for medicinal purposes is advised because, depending on the fertilisation, there may be higher production of cardiotonic heterosides, which are considered toxic.

A população de plantas pode afetar a produtividade e a composição química dos grãos de soja, por ocorrer competição intraespecífica pelos recursos ambientais disponíveis. Assim, objetiva-se com o estudo identificar o efeito da população de plantas, em duas cultivares de soja, semeadas em dois anos agrícolas, no rendimento de óleo e de proteína em soja cultivada sob cerrado. Os experimentos foram implantados no município de Palmas, Tocantins (latitude: 10º 45 sul; longitude: 47º 14 oeste; e altitude: 220 m), um na safra 2018/19, em semeadura realizada em 08/12/2018, e outro na safra 2019/20, em semeadura efetuada em 17/12/2019. O delineamento experimental utilizado em cada ensaio foi o de blocos casualizados (DBC), com 10 tratamentos e quatro repetições. Os tratamentos foram dispostos em esquema fatorial 2 x 5, representado por dois cultivares de soja (BÔNUS 8579 RSF IPRO e NS 8383 RR) e cinco populações de plantas (200, 250, 300, 350 e 400 mil ha-1). Foram avaliados os rendimentos de óleo e de proteína (Kg ha-1). As populações de plantas promoveram variações nos rendimentos de óleo e proteína. Os anos agrícolas influenciaram nos rendimentos de óleo e proteína. Maiores rendimentos de proteína flutuaram entre as populações de plantas de 273,9 mil plantas ha-1 (Bônus) e 306 mil plantas ha-1 (NS 8383 RR), e rendimento de óleo variou entre as populações de plantas de 266,7 mil plantas ha-1 (Bônus) e 310,8 mil plantas ha-1 (NS 8383 RR). A cultivar NS 8383 RR apresentou os maiores rendimentos de óleo e proteína nas diferentes populações.

A Amazônia brasileira destaca-se pela sua biodiversidade, sendo ampla fonte de recursos biogenéticos. Além da sua expressiva fauna e flora, existe uma grande biodiversidade invisível, encontrada na microbiota do solo, composta principalmente por fungos e bactérias. Esses micro-organismos são essenciais para conservação do meio ambiente, participam em diversos processos na manutenção do ecossistema, como ciclos biogeoquímicos, fertilidade e estrutura dos solos, e na decomposição e mineralização da matéria orgânica. Também são recursos genéticos para diversos bioprocessos: biotecnológicos, biorremediação de solos contaminados, biodegradação de agrotóxicos, biofertilizantes e bioestimulantes do crescimento de plantas. Atualmente, desmatamentos e queimadas são os principais causadores da degradação florestal e perdas na biodiversidade amazônica, afetando também os fatores abióticos, como temperatura e umidade, que influenciam o solo, causando estresse à microbiota. O estudo foi realizado por meio de levantamento bibliográfico, sendo consultados livros, dados publicados pelo Instituto Nacional de Pesquisas Espaciais (INPE) e artigos indexados nas principais bases de pesquisas. Com base no levantamento bibliográfico e a fim de apresentar um melhor entendimento sobre os impactos que a degradação da Amazônia pode causar na microbiota do solo, esse artigo foi subdividido nos tópicos: desmatamento e queimas na Amazônia, biodiversidade invisível, importância da microbiota do solo, impactos do desmatamento e queima na microbiota. Considerando o potencial da microbiota amazônica em enriquecer a biodiversidade, essa revisão objetiva abordar os impactos que o desmatamento e o fogo podem ter na biodiversidade microbiana do solo.

A destinação final do lodo de esgoto é uma problemática ambiental agravada pelo crescimento populacional. Esse resíduo, após um processo de estabilização, é chamado de biossólido e pode ser utilizado na produção de mudas florestais. O objetivo deste trabalho foi avaliar a sobrevivência e o crescimento de mudas de progênies selecionadas de Eremanthus erythropappus cultivadas em diferentes composições de substratos com biossólido. As sementes foram coletadas em uma árvore matriz de cada uma de cinco procedências (Carrancas, Baependi, Morro do Pilar, Delfim Moreira e Itabirito). A formulação dos substratos foi realizada com porcentagens crescentes de biossólido (0%, 30%, 60% e 90%), decrescentes de fibra de coco (90%, 60%, 30% e 0%), com uma porcentagem constante de vermiculita (10%). Aos 60 dias após a semeadura foi avaliada a sobrevivência e aos 120 dias foram mensurados a altura e diâmetro das mudas. Não houve interação entre as progênies e a formulação do substrato. As progênies diferiram em sobrevivência e altura, sendo a de Carrancas com os piores resultados. Existe um potencial de seleção de progênies na fase de muda. O substrato sem biossólido resultou em mudas com altura e diâmetro superiores. O uso de biossólido não é recomendado para mudas de Eremanthus erythropappus.

Os reguladores vegetais podem resultar em alterações no desenvolvimento das plantas e nos processos fisiológicos, limitando altura de planta, proporcionando maior número de nós reprodutivos e, por fim, incremento na produtividade. O objetivo da pesquisa foi avaliar o efeito de diferentes reguladores vegetais na cultura da soja, em diferentes concentrações, visando identificar a melhor combinação regulador/concentração. O experimento foi realizado no ano 2018/19, com semeadura no mês de dezembro, conduzido em Gurupi (TO). O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, sendo os tratamentos dispostos em esquema fatorial 5x4+1, sendo o primeiro fator constituído por cinco reguladores vegetais (GA3; ethephon; Cinetina+GA3+AIB; lactofen; e 2,4-D), o segundo fator por quatro concentrações para cada produto (dose recomendada, 50% abaixo, 50% acima e 100% acima), além da testemunha adicional onde não houve aplicação dos produtos. Foram avaliadas as seguintes características agronômicas: altura das plantas, número de vagens por planta, número de grãos por planta, peso de mil grãos e produtividade de grãos. Os dados foram submetidos a análise de variância, sendo as concentrações submetidas à análise de regressão e as médias dos reguladores, em relação à testemunha, ao teste de média de Dunnett. Houve efeito dos reguladores vegetais para as características estudadas. As concentrações dos produtos, acima das recomendadas, podem resultar em inibição do crescimento das plantas, mas também causar efeitos prejudiciais às plantas de soja. O produto Cinetina+GA3+AIB, na concentração 0,0675+0,0375+0,0375 g ha-1, proporcionou inibição no desenvolvimento da altura de plantas e incremento com maior número de vagens por planta e maior número de grãos por planta, refletindo maior produtividade de grãos.

BACKGROUND: Cellular senescence is a stress response, triggered by various stimuli such as chemotherapy treatment and causes G0/G1 cell cycle arrest followed by the production of a senescence associated secretory phenotype. p53 considered to be a modulator of these events although the precise mechanisms of it remains not clear.
AIMS: To determine the non-apoptotic functions of the p53 protein the formation of the senescence associated secretory phenotype phenotype of melanoma cells under the treatment of the cytostatic agent dacarbazine.
MATERIALS AND METHODS: The study was conducted on BRO and SK-MEL-2 skin melanoma cell lines. Melanoma cells were were treated by cytostatic agent dacarbazine. Then immunocytochemical study was performed to determine the proportion of G0-positive cells and the expression of the tumor suppressor protein p53. A bioinformatic analysis was accomplished to identify for p53 regulators with determining of miR-155-5p levels in exosomes released by dacarbazine-treated melanoma cells.
RESULTS: The cytostatic drug dacarbazine increases the proportion of cells residing in the G0 phase of the cell cycle. Onco-microRNA miR-155-5p was expressed in the exosomes of the two studied cell lines BRO and SK-MEL-2 of skin melanoma. Changes in the expression level of p53 correlate with changes in miR-155-5p microRNA expression. The absence of changes in p53 expression in BRO melanoma cells may be due to the absence of changes in miR-155-5p expression levels. In the BRO cell line, no changes in the expression of the oncosuppressor p53 were observed with an increased percentage of G0-positive cells, which may be associated with the activation of other mechanisms of cell cycle arrest in the G0/G1 phase.
CONCLUSIONS: Heterogeneous effect of the cytostatic agent dacarbazine on melanoma cells was revealed. For the SK-MEL-2 cell line, dacarbazine induces the release of senescence associated secretory phenotype by inhibiting exosomal production of miR-155-5p, which activates the p53 oncosuppressor, which was not observed in the BRO line.
