Simple Seed-vacuum Protocol for Agrobacterium-mediated Virus Induced Gene Silencing (VIGS) in Sunflower Helianthus annuus L. v1
Authors: Mardini Majd
Published: September 2023

Virus-Induced Gene Silencing (VIGS) stands out as one of the most powerful tools for functional genomic research. The underlying principle of the VIGS system is based on harnessing the innate defense mechanism of the studied species to induce post-transcriptional gene silencing. In brief, the process involves introducing a modified viral constructs carrying a fragment of the host targeted gene (300-500 bp). The introduced virus will prompt a group of enzymes within the plant's defense system, setting off the degradation of viral RNA products together with any similar sequences in the cell, including the host’s own mRNA. As a result, the expression level of the targeted gene is altered or, in optimal scenarios, completely silenced. The introduction of the viral constructs is typically achieved through agrobacterium-mediated transformation. Numerous agrobacterium-VIGS systems have been firmly established for a number of crops and model plant species (Zhang Y. et al., 2019; Ramegowda V. et al., 2014). However, it is important to note that the infiltration procedure and viral construct often exhibit strong species-specificity. And as research advances, customizing new protocols becomes imperative for successful implementation across diverse plant species. Here, we represent a simple and reproducible agrobacterium-mediated VIGS protocol for sunflower (Helianthus annuus L.). Our methodology is seed vacuum-based without the necessity for pre-germination, MS medium recovery, or even seeds sterilization. Within this protocol, we provide comprehensive instructions that ensure the consistent replication of results. For demonstration we used PHYTOENE DESATURASE gene (PDS) of Helianthus annuus as a target for VIGS. The viral constructs are derived from Tobacco Rattle Virus (TRV) (Liu Y. et al., 2002). Information on vectors assembly and post-experimental validation are also provided. The protocol's reproducibility has been rigorously tested on a breeding line and various commercial sunflower cultivars.

The aim of this study is to investigate the characteristics of Textile ETP and Tannery sludges and strength characteristics of cement-sludge mortar. The textile Effluent Treatment Plant (ETP) and tannery sludges have the potential to become a serious environmental burden for Bangladesh in the future because of their high rate of generation, with a very limited safe disposal option. On the other hand, day by day the demand and price of cement are increasing. This study was devoted to evaluate the technical feasibility of utilizing textile ETP and tannery sludges in cement mortar both as separate and mixed modes. An attempt was taken to replace 5%, 10%, 15% and 20% by weight of cement in mortar with textile ETP and tannery sludges both as a separate and mixed modes. To evaluate the characteristics of the textile ETP and tannery sludges, the pH, moisture content, organic matter content, chemical composition (XRF), TCLP (Heavy Metal) tests were studied. The initial and final setting time, compressive strength, tensile strength, and water absorption of mortar by partial replacement of cement by textile ETP and tannery sludges both as separate and mixed modes were studied to evaluate the properties of cement-sludge mortar. It was found that the textile ETP and tannery sludges both as separate and mixed modes can be a replacement of cement up to 10% in cement mortar and can be used for the purposes of S-type of mortar. The textile ETP sludge as a separate and mixed modes of the sludges can be a replacement of cement up to 20% and can be used for the purposes of N-type of mortar.

Published: September 2023

Waste rubber tires are materials that have a negative impact on the environment. Therefore, it is essential to use waste rubber recycled from damaged tires (CRWA) in geopolymer concrete (GPC) by different partial volumetric replacements to natural coarse aggregate (0, 10, 20, 25%) after preparation to a gradation similar to that for natural coarse aggregate. Calcium oxide and silica fume were substituted in metakaolin (MK) at 5 wt%. The GPC mix consisted of MK after modification, coarse aggregate, fine aggregate sodium hydroxide solution, sodium silicate solution, superplasticizer, and extra water, with quantities of 372, 911, 83, 192, 4, and 52 kg/m3, respectively. It is clear from the experimental results that the mechanical properties of geopolymer concrete decreased with the increase in the content of the crumbed rubber waste aggregate. The compressive, splitting tensile, and flexural strengths decreased by approximately 38.6, 44.6, and 52.6%; 10.6, 15.2 and 21.2%; and 6.25, 12.75, and 16.5% when the crumbed rubber aggregate was 10, 20 and 25%, respectively. In addition to recycling the rubber waste from damaged tires, desirable properties can be obtained, starting from not using water in curing GPC and rapid strength development at early ages. There is a clear improvement in the thermal properties and weight of GPC containing CRWA by reducing the thermal conductivity and dry density by including 10, 20, and 25% CRWA compared with the reference GPC without this waste material.

Energy from coal-fed thermal power plants is provided at the cost of the generation of coal ash. Coal bottom ash (CBA) is an ash generated in coal-fed power plants which is landfilled. Existing literature reports the potential of CBA as a replacement for Portland cement (PC) and natural fine aggregates (NFA) in concrete. Carbonation is an important durability parameter of concrete having fatal consequences at later ages if not estimated and controlled as it leads to corrosion in reinforcement. In the present study, experimental, microstructural, and statistical analysis along with life cycle assessment was performed to investigate the combined effect of two-hour grinded CBA (GCBA) as PC (10-30%) and raw CBA as NFA replacement (0-50%) on compressive strength and carbonation resistance. Accelerated carbonation tests were performed at an exposure of four weeks after 28 and 90 days of curing. Among CBA-based concrete mixes, concrete with 20% GCBA and 25% CBA (G20C25) reported higher compressive strength and carbonation depth owing to pozzolanic reactivity and filler effect of fine CBA particles. However, G20C25 resulted in comparable performance in comparison with the control mix in terms of strength and carbonation resistance. The findings of X-ray diffraction spectroscopy, scanning electron microscopy and Fourier transform infrared spectroscopy also validate the trends. The mathematical models derived for the carbonation resistance and strength were well-fitted. Multi-objective optimization recommended 21.5% GCBA and 29.8% CBA as the optimum amount that resulted in 20.08% and 19.40% lower carbon footprints and eco-costs compared to control mix.

Shares are one of the most common objects for investment. Individual investors both invest directly in the securities of a certain company and invest in various funds created from the shares of public companies according to different structures. For a significant share of the population of highly developed countries with a developed financial infrastructure, income from investments is an important source of passive income that increases the financial security of households in case of temporary loss of work, illness, or other adverse circumstances. Therefore, the analysis of securities quotes to select assets for further investment is an extremely important task. When studying the dynamics of stock quotes, due to the significant role of risk, volatility is an essential component. To correctly respond to possible spikes in volatility caused by certain events, and forecasting their duration, it is important to use analysis. Econometric analysis with the help of time series research models is selected as the optimal option for the study of the dynamics of stock quotations. Due to the high quality, the most common is the simulation of securities quotations using a combination of ARIMA-GARCH models. Various modifications of this method were implemented in this work using the R programming language. Data on the daily returns of Microsoft and Pfizer shares were used for the analysis. At the first stage of the modeling process, a transition to log- returns was made, graphs of the initial time series, autocorrelation functions were constructed, time series were checked for stationarity according to the Dickey-Fuller test, and the optimal specification of the ARIMA model was obtained for both indices. At the same time, when checking the residuals of the models for autocorrelation and the ARCH effect, positive results were obtained, which indicates the inadequacy of using only the ARIMA model and the need for GARCH. As a result of sorting through various GARCH specifications, optimal ones were chosen for two stocks, both of which take into account the asymmetric impact of disturbances depending on their signs. The resulting models were tested by the Leung-Box test, the ARCH LM test, and the Pearson test for specification optimality. Based on the obtained models, a forecast was built using the sliding window method and compared with the actual time series data. The quality of the forecasts of the optimal models and other specifications was also correlated to check that the minimum forecast error was obtained using the selected models. All results confirmed the correctness of the built models, which allows them to be used for analysis and forecasting already for further periods.

Published: September 2023

The paper aimed to examine the e-governance of the agricultural sector of Ukraine based on the State Agrarian Register. The digital transformation process of Ukrainian agriculture and the digital state register are considered. It was found that the main purpose of the platform is to provide financial and humanitarian assistance to farmers, both state and international. The background to its creation was excessive bureaucracy, lack of transparency, and corruption. From the very beginning, state support programs were offered on the basis of the state agency. More than 30,000 users registered in the first month. More than 30,000 users registered in the first month. In the next five months registered additional 70,000 users. Support from international donors was considered. The World Bank and the Food and Agriculture Organization of the United Nations have joined in supporting Ukrainian farmers. The expected results of the system implementation are simplified registration of farmers for financial support, automatic verification of their status through access to other state registers and cadastres, rapid application for financial support from the comfort of their homes or offices, rapid verification of eligibility for support, the ability to assess the effectiveness of support measures and publicity for the distribution of state support funds. A SWOT analysis of the State Agrarian Register was carried out. Threats include data leakage, cyber-attacks, and possible technical problems. Simplified access to information, optimization of farms and increased efficiency, increased transparency in the agricultural sector, improved access to finance, and improved traceability of the supply chain are the main benefits that Ukraine's agricultural sector could gain from the implementation of e-governance. The main opportunities are increasing the level of digital literacy of citizens and the growth of the agricultural sector through government/international support and the use of modern technologies.

The article is focused on researching and developing strategies for the diversification of international activities for enterprises in the Ukrainian metallurgical industry. It is emphasized that the metallurgical industry is of strategic importance to the economy of Ukraine, as it is a net exporter, generates numerous job opportunities, contributes significantly to the country's GDP, and attracts foreign capital investments. Various international diversification strategies are proposed, including diversification of sales geography, diversification of production, and diversification of the product portfolio. A comparative analysis is conducted to determine the advantages and disadvantages of each strategy, to identify the most relevant approach for specific enterprises. The comparative analysis revealed that diversification of international activity is the most effective strategy for minimizing risks and maintaining the profitability of companies. Three diversification strategies for the international activities of Ukrainian metallurgical enterprises are proposed, which include diversification of sales geography, diversification of production, and diversification of the product portfolio. Recommendations and measures for implementing each of the proposed international diversification strategies are presented. It is determined that, given the current war conditions, the priorities for metallurgical enterprises in developing strategies for international activities are the optimization of supply chains, including the creation of joint ventures with neighboring countries, providing conditions for the creation of high-value-added products, improving production capacities, and taking into account the factor of decarbonization to reduce the impact of the Carbon border adjustment payment.

More than two decades after the legalisation of gambling and almost three decades after the beginning of the organisation of lotteries in Lithuania (the Gaming Law of the Republic of Lithuania came into force in 2001 and the Law on Lotteries in 2004), it is already possible to discern the trends in the development of this business and the impact of this business on the individual and on society. Gambling and lotteries are seen ambiguously both in the work of researchers and in society: some see the activity as a fun pastime or a form of leisure, while others argue that it is an addiction with negative psychological, social and economic consequences for the individual, the family and society. In Lithuania, there has been very little research on the impact of gambling and lotteries on individuals and society, compared to other countries such as Italy, the United States, Australia, New Zealand and Canada. In these countries, gambling and lotteries have a very long and deep tradition, are a very important area of the economy (business) and a popular way of spending leisure time. This article examines the development trends of the gambling and lotteries market in Lithuania. The study made use of quarterly time series data including from 2004Q1 to 2021Q4. During the research we established, that every year, the income from land-based gambling decreases and the gross income from online gambling increases. In 2021, 53 percent of the gross gambling and lottery revenue structure was from online gambling. Additionally, according to the of Autoregressive Distributed Lag (ARDL) model, the paper estimated the relationship between the gross domestic product of Lithuania and the tax receipts of gambling and lotteries to the Lithuanian state budget. According to the study, GDP growth influences gambling and lottery tax revenues directly, without postponed effect, but at the same time, there is a fairly strong inertia in budget revenues from gambling and lottery.
Scientific personality of Ilya Kucherenko in Ukrainian grammarology
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Riznyk Serhii
Published: September 2023

The article is devoted to the analysis of the scientific contribution of Taras Shevchenko Kyiv University professor Ilya Kucherenko to the development of the grammatical theory of word combinations and sentences, the innovative principles of classification of parts of speech, the theory of cases, the syntactic status of homogeneous clauses, the function of the preposition in a syntactic combination, the syntactic nature of phraseological units, the principles of logical consistency in definition of key concepts and mechanisms of language structure. His innovative grammatical concept lies in the application of the monocriterial principle for dividing words into parts of speech. The real meaning of the word was chosen as the sole criterion. According to their real meaning, the scientist divides all the words of the language into seven classes (noun, adjective, numeral, verb, adverb, participle, conjunction) and in each of these classes he distinguishes three levels of semantics: the level of specific semantics, the level of generalized semantics and the level of generalized indicative semantics. The article analyzes the syntactic function of the preposition in the phrase. I. Kucherenko believes that the preposition does not help the noun to implement the noun semantics, but on the contrary, it requires the noun to specify the generalized-indicative level of its semantics and is combined with the noun dependent on it by the grammatical control link. The grammarian considers stable (phraseological) compounds to be not lexical, but syntactic units, since the words in them are combined in the same way as in free word combinations. The article also examines a number of other syntactic phenomena (monosyllabic sentences, homogeneous clauses, vocative), which I. Kucherenko explains using strictly logical methods of analysis. The grammatical concept of Ilya Kucherenko is analyzed in comparison with the views of other scientists of the 60s–90s of the 20th century.

Legal Support of Private Interest
Authors: Imekova M. P.
Published: September 2023

There is no single point of view in legal science regarding the criteria for distinguishing public and private law. Moreover, there is no theory that would be recognized by most researchers. The reason lies in the fact that scientists in their works analyze public and private law in various aspects, in this regard, they identify such criteria of differentiation that cannot be universal.

The paper considers public and private law from the standpoint of instrumental theory and define it as a system of legal means designed to satisfy public or private interests, respectively. The undoubted advantage of this theory is that it is not focused on the search for universal criteria for distinguishing public law from private law, but suggests focusing on legal means aimed at creating the conditions necessary to meet the diverse legal interests of legal subjects. It is proved that public and private law are an integral part of legal support. Legal support, depending on the purpose (the type of interest being satisfied — public or private), is proposed to be divided into two types: public law and private law. It is established that support of interests in private law differs from that one in public law in the following. It allows for the possibility of choosing or changing behaviors provided for by regulatory legal means through the manifestation of legal initiative on the part of legal entities, and the form of implementation of such an initiative is self-regulation. Legal relations on the implementation of legal means arising within the framework of private law enforcement of interests arise between legally equal subjects. Private law support of interests is designed to mediate such a type of activity as legal (legal realization) activity. Private law support of interests is characterized by such a type of legal regulation as permissive.
El rechazo al sistema constitucional en la Intendencia de Nuevas Poblaciones durante el Trienio Liberal
Authors: Hamer Flores Adolfo
Published: September 2023

Las Nuevas Poblaciones de Sierra Morena y Andalucía disfrutaron a partir de 1767 de un régimen foral que les garantizaba una serie de privilegios y exenciones. Las Cortes de Cádiz, no obstante, consideraron incompatible con la Constitución su permanencia, por lo que fue suprimido en 1813 y, nuevamente, en 1820. El objetivo de este trabajo consistirá en analizar la resistencia que sus vecinos mostraron al liberalismo, las estrategias de los antiguos gobernantes absolutistas para seguir ocupando puestos de poder en ellas y, sobre todo, la decidida colaboración que estos prestaron para la captura de Rafael del Riego en 1823.

La influencia de Maurice Hauriou en Carl Schmitt: del giro institucionalista al pensamiento del orden concreto
Authors: Wieczorek Tomás
Published: September 2023

El artículo se centra en la influencia de Maurice Hauriou en el giro institucionalista que condujo a Carl Schmitt desde el decisionismo al pensamiento del orden concreto. Para ello, y luego de un encuadramiento histórico y crítico, se aborda la cuestión de la “obediencia previa”, se cotejan sus respectivas visiones de los derechos individuales y de las garantías institucionales en la constitución moderna, se analiza la recepción schmittiana de la doctrina de la superlegalidad de Hauriou, y se comparan la teoría de la institución del francés con el pensamiento del orden concreto del alemán; a cada uno de estos aspectos se dedica una sección. Como resultado, se concluye que la importante influencia de Hauriou en el giro institucionalista de Schmitt palidece con la definitiva adopción por parte de este último de su pensamiento del orden concreto.

Carl Schmitt en la Constitución española de 1978. Los apuntes de García-Pelayo
Authors: Vila Conde Francisco
Published: September 2023

La unión entre Carl Schmitt y una Constitución liberal y democrática parece cosa imposible a buena parte de la academia. Quién podría vincular, dirán, al «Kronjurist del nazismo» con una Constitución liberal y democrática; quien ose hacerlo, continuarán, no sabe lo que dice, es un ignaro completo en temas de derecho e historia constitucionales. Sin embargo, nada más y nada menos que Manuel García-Pelayo, el que fuera primer presidente del Tribunal Constitucional y maestro indiscutido e indiscutible de la ciencia constitucional en nuestro país, será quien lleve las teorías schmittianas a la Constitución española de 1978. En su Inédito sobre la Constitución española de 1978, que vio la luz el pasado 2021, García-Pelayo ofrece una lectura schmittiana de la Constitución que, en lo que nos es dable, tratamos de comentar y desarrollar en el presente texto para, así, hacer ver la compatibilidad entre Carl Schmitt y una Constitución liberal y democrática.

Organismos internacionales promueven el desarrollo de la alfabetización mediática con la finalidad de favorecer la igualdad de oportunidades y la construcción de una sociedad más justa, equitativa y sostenible en línea con la Agenda 2030. Pese a ello, la alfabetización mediática del profesorado de educación de adultos ha quedado rezagada, aumentando la brecha en el ecosistema digital. Este trabajo presenta una investigación paralela a un proyecto de intervención sobre la alfabetización mediática y los ODS, dirigido a docentes de jóvenes y adultos de República Dominicana. Contempla dos objetivos: evaluar la efectividad de una propuesta formativa sobre esta temática y determinar la transferencia de los aprendizajes al aula. Para ello, se aplica un diseño mixto mediante cuestionario y grupos de discusión. Los resultados manifiestan la evolución en los aprendizajes vinculados al marco conceptual de la alfabetización mediática, el funcionamiento de los medios y su puesta en práctica vinculada con el desarrollo sostenible. Si bien, el profesorado considera necesario una mayor adaptación de la intervención al contexto dominicano para optimizar la transferencia al aula. Esta investigación aporta la evidencia de una propuesta formativa con capacidad de réplica e institucionalización en la formación continua del profesorado de educación de adultos.

BACKGROUND: Sufficient endometrial blood supply in the mid-secretory phase of the menstrual cycle is a key to a successful pregnancy achievement, and a decreased spiral artery blood flow resistance determined by the Doppler is known to be positively associated with successful in vitrofertilization outcome. Particular aspects of endometrial blood flow in women with uterine fibroids might affect the efficiency ofin vitrofertilization and intra cytoplasmic sperm injection cycles.
AIM:The aim of this study was Doppler-based determination of the uterine and spiral artery blood flow resistance in women with uterine fibroids throughout controlled ovarian stimulation inin vitrofertilization cycles, depending on the clinical pregnancy rate.
MATERIALS AND METHODS:Doppler ultrasound spiral artery blood flow evaluation was performed in 83 women throughout thein vitrofertilization cycle. Intramural uterine fibroids were detected in 44 women, and 39 women with no uterine fibroids comprised the comparison group. All women underwent a Doppler study of spiral artery blood flow on the second or third day of the menstrual cycle (at the start of thein vitrofertilization protocol) and on the day of embryo transfer. Thein vitrofertilization efficiency was determined by the onset of clinical pregnancy after visualizing the gestational sac in the uterine cavity during ultrasound examination on the 2025th day after embryo transfer.
RESULTS:The values of the uterine and spiral artery blood flow resistance in the uterine fibroids group were determined to be significantly lower than those in the comparison group. Considering the identified influence of decreased spiral artery blood flow resistance on the results ofin vitrofertilization cycles in the comparison group, we have analyzed the dependence of the efficiency of the cycles based on the rate of the spiral artery blood flow resistance decline. Thus, a significantly more reliable decline in the pulsatility index was revealed in pregnant women from the comparison group throughout thein vitrofertilization cycle compared to women with negative results. In women with uterine fibroids, the pulsatility index decline did not differ depending on the onset of pregnancy, and the decline rate differed significantly from that in the comparison group.
CONCLUSIONS:Uterine fibroids are associated with a stable decline in the uterine and spiral artery blood flow resistance. This leads in turn to increased endometrial vascularization throughout the stimulation cycle inin vitrofertilization programs and negatively affects the blastocyst implantation ability.

The antenatal mothers with gestational age 28 and above, with anxiety score above 21 according to the Prenatal Anxiety Screening Scale (PASS) were included in the study, and mothers with a history of substance dependence, psychotic disorders, or any other major psychiatric disorders, and epilepsy were excluded from the study. Probability sampling was used. Data were collected after ethical clearance and informed consent. Following to the pre-test, which includes a collection of demographic data, the antenatal mothers in the experimental group received the Benson relaxation therapy. And post-test was conducted among both groups on the fifteenth day.
Results: The mean age group of the antenatal mothers were in age group of 26-33 years. 46.7% of samples have a secondary level of education. The majority (53.3%) are self-employed. Sixty percent of the mothers are primigravida. Fifty-seven percent are residing in a rural area and belong to joint family. There is a significant difference between the post-test score of the experimental and control group at the p=0.001 level. The Benson relaxation therapy is effective in reducing prenatal anxiety among antenatal mothers.
Conclusions: Benson relaxation therapy is a simple, effective and mind-body relaxation technique to relieve anxiety among pregnant women.
Intimate partner violence; breaking the silence on male victims in Nigeria

Globally, men have always been seen as perpetrators of aggression in romantic relationship which constitute intimate partner violence (IPV). In Nigeria, they are mostly considered as the villains due to the patriarchal nature of the society. However, there have many cases of violence by intimate partners where men were the victims. Very few of such cases were reported either to the hospital or to the police due to many reasons ranging from sociocultural, ethnic, economic and religious values among others. In a patriarchal society like Nigeria, men experience various form of violence which could be physical, psychological, sexual and socioeconomic from intimate partners. Therefore, this article attempts to review the reported incidence of male victims of IPV in Nigeria and the peculiarities involved while providing recommendations. Some of the factors identified for the low incidence report includes; lack of routine screening for domestic violence in health facilities, the fact that psychological violence is not considered as violence in some Nigerian society, shame about disclosing family violence, poor socioeconomic status and many more. Additionally, a major predictor of female-perpetrated IPV was childhood exposure to violence. This paper recommends that several actions which would improve the report of IPV against men while ameliorating IPV in Nigeria may involve: raising public awareness, legal protection, increasing health care worker sensitivity, provision of support services, research and proper data collection among others.

Schwannomas are benign, encapsulated, slow-growing, tumours deriving from the peri neural cells located in the nerve sheath. They can arise from any cranial, peripheral or autonomic nerves, and show a predilection for the head and neck region. They may produce secondary symptoms like nasal obstruction, dysphagia, and hoarseness of voice depending upon the location of the tumour. Preoperative diagnosis is difficult, relying on clinical suspicion, and confirmed by surgical pathology. Preoperative imaging or fine needle aspiration cytology may help to reveal diagnosis. The definitive diagnosis is made by histopathological examinations. A 28 years old female patient presented to the OPD with painless swelling on the left lateral side of the neck since 1 year. The swelling was mobile, non-tender, non-pulsatile firm in consistency measuring 4×3 cm with no bruit. MRI neck with contrast was done which revealed a moderately enhancing lesion of size 7×4×3 cm in the left carotid sheath. The tumour was approached by an anterior approach along the medial border of the sternocleidomastoid. Platysma and fascia were dissected followed by carotid sheath to reach the tumour. As the mass was seen arising from a branch of the ansa cervicalis, it had to be sacrificed.

Mulheres escritoras em bibliografias brasilianas
Authors: Marques Pereira Araújo Diná , José Nascimento da Silveira Fabricio
Published: September 2023

O presente artigo sintetiza parte das discussões desenvolvidas em uma pesquisa de doutoramento que se inscreve no campo dos estudos histórico-bibliográficos, cujos objetos de análise são bibliografias de temática brasiliana. O propósito é investigar a presença de mulheres escritoras nessas bibliografias visando identificar silenciamentos que a escrita bibliográfica possibilita. Em face disso, defende-se que pesquisar a memória escrita a partir das brasilianas oportuniza trazer à cena mulheres que têm sido apagadas da historiografia e da memória bibliográfica, resgatando suas histórias e produções sobre o Brasil. Em sua dimensão teórica, o trabalho dialoga com perspectivas multidisciplinares, as quais abrangem estudos sobre a Bibliografia e a História Cultural das Mulheres. Em termos metodológicos, trata-se de uma análise bibliográfico-documental centrada em identificar mulheres escritoras. Por se tratar de uma pesquisa em curso, os resultados consistem na apresentação das bibliografias selecionadas, do levantamento dos dados referentes ao quantitativo de mulheres escritoras e em reflexões iniciais acerca destes marcadores qualiquantitativos.
